    BACKGROUND: No direct cost comparison has been conducted between percutaneous cryoablation (PCA) and robot-assisted partial nephrectomy (RAPN) for clinical T1a renal cell carcinoma (RCC) in Japan. This study aimed to compare their costs. METHODS: We retrospectively analyzed data from 212 PCAs (including 155 with transcatheter arterial embolization) and 119 RAPN cases performed between December 2017 and May 2022. RESULTS: PCA patients were older with higher American Society of Anesthesiologists scores, Charlson Comorbidity Index, and history of previous RCC treatment, cardiovascular disease, and antithrombotic drug use than RAPN patients. PCA was associated with a significantly shorter procedure time and hospitalization duration with fewer major complications than those associated with RAPN. While PCA incurred a slightly lower total cost (1,123,000 vs. 1,155,000 yen), it had a significantly higher procedural cost (739,000 vs. 693,000 yen) and markedly worse total (- 93,000 vs. 249,000 yen) and procedural income-expenditure balance (- 189,000 vs. 231,000 yen) than those of RAPN. After statistical adjustment, PCA demonstrated significantly higher total (difference: 114,000 yen) and procedural costs (difference: 72,000 yen), alongside significantly worse total (difference: - 358,000 yen) and procedural income-expenditure balances (difference: - 439,000 yen). The incremental cost-effectiveness ratio was more favorable for PCA than for RAPN. CONCLUSION: For high- risk patients, PCA demonstrated a safer option with shorter hospitalization duration than those of RAPN. Although PCA was more cost-effective, its higher procedural cost and unfavorable income-expenditure balance require careful evaluation, especially for large tumors that require three or more needles.

    BACKGROUND: Identifying patients on dialysis among those with an estimated glomerular filtration rate (eGFR) < 15 mL/min/1.73 m2 remains challenging. To facilitate clinical research in advanced chronic kidney disease (CKD) using electronic health records, we aimed to develop algorithms to identify dialysis patients using laboratory data obtained in routine practice. METHODS: We collected clinical data of patients with an eGFR < 15 mL/min/1.73 m2 from six clinical research core hospitals across Japan: four hospitals for the derivation cohort and two for the validation cohort. The candidate factors for the classification models were identified using logistic regression with stepwise backward selection. To ensure transplant patients were not included in the non-dialysis population, we excluded individuals with the disease code Z94.0. RESULTS: We collected data from 1142 patients, with 640 (56%) currently undergoing hemodialysis or peritoneal dialysis (PD), including 426 of 763 patients in the derivation cohort and 214 of 379 patients in the validation cohort. The prescription of PD solutions perfectly identified patients undergoing dialysis. After excluding patients prescribed PD solutions, seven laboratory parameters were included in the algorithm. The areas under the receiver operation characteristic curve were 0.95 and 0.98 and the positive and negative predictive values were 90.9% and 91.4% in the derivation cohort and 96.2% and 94.6% in the validation cohort, respectively. The calibrations were almost linear. CONCLUSIONS: We identified patients on dialysis among those with an eGFR < 15 ml/min/1.73 m2. This study paves the way for database research in nephrology, especially for patients with non-dialysis-dependent advanced CKD.

    PURPOSE OF REVIEW: To review the current status of kidney tumor ablation in patients with substantial kidney impairment. RECENT FINDINGS: Few reports of kidney tumor ablation in such patients have recently been published. The reported prevalence of patients with stage 4 or 5 chronic kidney disease (CKD) among patients undergoing ablation is 2.0%-10%. In patients with stage 4 or 5 CKD, local tumor control rates were 88%-100%. The effect of ablation on CKD stage is unclear, and the observed deteriorations in kidney function are consistent with both the effect of cryoablation and the natural course of advanced CKD. According to guidelines, active surveillance may be selected. The goals of treatment are complete tumor removal and maintenance of kidney function, both of which can be met by ablation. Given the limited treatment options, ablation may play a pivotal role in the management of patients with advanced CKD.

    Abstract

    Purpose

    To retrospectively evaluate cryoablation combined with prior transcatheter arterial embolization (TAE) for renal cell carcinoma (RCC) in non-dialysis patients with stage 4 or 5 chronic kidney disease (CKD).

    Materials and methods

    Patients with stage 4 or 5 CKD undergoing TAE and cryoablation for RCC between May 2012 and October 2021 were included. TAE was selectively performed using iodized oil with absolute ethanol or gelatin sponge 1–14 days before cryoablation. Local efficacy, safety, and changes in renal function were evaluated.

    Results

    Nine patients (seven men and two women; median age, 64 years; range 52–88 years) with nine RCCs (mean diameter, 3.0 ± 1.0 cm; range 1.7–4.7 cm) were included. The mean pre-treatment estimated glomerular filtration rate (eGFR) was 24.2 ± 5.6 ml/min/1.73 m2 (range 10.4–29.2 ml/min/1.73 m2). The mean amount of contrast medium used in TAE was 58 ± 29 ml (range 40–128 ml). Except in one patient (grade 3 pyelonephritis), no grade ≥ 3 complications occurred. During the follow-up period (median, 18 months; range 7–54 months), no local tumor progression occurred. In two patients with pre-treatment eGFR of &lt; 20 ml/min/1.73 m2, hemodialysis was initiated at 3 and 19 months after cryoablation. At their last follow-up, the remaining seven patients showed a decrease of 6.2 ± 5.3 ml/min/1.73 m2 (range 0.7–17.2 ml/min/1.73 m2) in their eGFR.

    Conclusion

    Cryoablation combined with TAE for RCC in non-dialysis patients with stage 4 or 5 CKD was effective and safe, with an acceptable impact on renal function.

    PURPOSE: To explore what extent of ablative margin on CT immediately after radiofrequency ablation (RFA) is required to reduce local tumor progression (LTP) for colorectal cancer (CRC) lung metastases in adult patients MATERIALS AND METHODS: This retrospective study was undertaken as a supplementary analysis of a previous prospective trial. Seventy patients (49 men, 21 women; mean age ± standard deviation, 64.9 ± 10.6 years; range, 37-82 years) underwent RFA for CRC lung metastases, and 95 tumors that were treated in the trial and followed up on CT at least 12 months after RFA were evaluated. The mean tumor size was 1.0 ± 0.5 cm (range, 0.4-2.8 cm). The ablative margin was estimated as the shortest distance between the outer edge of the tumor and the surrounding ground-glass opacity on CT obtained immediately after RFA. The impact of the ablative margin on LTP was evaluated using logistic regression analysis. Multivariable logistic regression analysis was also performed to identify the risk factors for LTP by adding the factors that are considered to be confounding factors to the ablative margin. The result was validated with multivariable logistic regression applying a bootstrap method (1,000 times resampling). RESULTS: The mean ablative margin was 2.7 ± 1.3 mm (range, 0.4-7.3 mm). LTP developed in 6 tumors (6%, 6/95) 6-19 months after RFA. The LTP rate was significantly higher when the margin was less than 2 mm (p=0.023). A margin <2 mm was also found to be a significant factor for LTP (p=0.048) on multivariable analysis and validated by the bootstrap method (p=0.025). CONCLUSION: An ablative margin of at least 2 mm is important to reduce LTP after RFA for CRC lung metastases.

    BACKGROUND: We prospectively evaluated the safety and efficacy of percutaneous cryoablation combined with transcatheter renal arterial embolization for the treatment of tumors ≥ 3 cm in diameter. METHODS: We included patients aged ≥ 20 years with histologically proven renal cell carcinoma with a tumor diameter ≥ 3 cm who were inoperable or refused surgery. Prior to ablation, transcatheter arterial embolization was performed using a mixture of absolute ethanol and iodized oil. All cryoablation procedures were performed percutaneously under computed tomography fluoroscopy guidance. The primary endpoint was safety, which was evaluated for adverse events using CTCAE version 4.0. The secondary endpoint was survival; overall survival, progression-free survival, and cancer-specific survival were calculated. RESULTS: From October 2013 to March 2016, 19 patients (mean age, 75 ± 13 years; 5 women, 14 men) were prospectively enrolled. The mean tumor diameter was 3.9 ± 0.7 (range 3.1-5.3) cm. Four grade 3 hematologic adverse events occurred, while no symptomatic grade ≥ 3 events occurred. The median follow-up period was 68 (range 52-84) months. During the follow-up period, two patients developed local tumor progression at 3 and 42 months after the initial ablative procedure; no patient showed distant metastasis. Two patients died from causes other than RCC. Overall survival, progression-free survival, and cause-specific survival were 100%, 95%, and 100% at 3 years, and 95%, 84%, and 100% at 5 years, respectively. CONCLUSION: Percutaneous cryoablation combined with prior TAE for the treatment of tumors ≥ 3 cm in diameter was safe and achieved favorable survival.

    Abstract

    Purpose

    To retrospectively assess the feasibility, safety, renal function, technique efficacy rate, and survival of patients with clinical T3a renal cell carcinoma (RCC).

    Materials and methods

    Sixteen cryoablation sessions were performed in 14 patients (10 men; mean age, 69.8 ± 10.5 years; range, 49–90 years) with 14 clear cell T3a RCCs (mean, 3.3 ± 0.9 cm; range, 1.9–5.2 cm). One patient was on dialysis. Transcatheter arterial embolization was performed before cryoablation in 15 sessions. The primary endpoint was the technique efficacy rate. The secondary endpoints included feasibility, safety, renal function, and survival.

    Results

    Cryoablation was technically successful in all RCC cases. In two RCCs, cryoablation was performed twice because of local tumor progression. No major adverse events were observed. All patients were alive without metastases, with a median follow-up of 45 months (6−93 months). Complete response was achieved by cryoablation in 11 RCCs (78.6%). The primary and secondary technique efficacy rates were 77.1% and 84.4% at 1 year, 57.9% and 73.9% at 3 years, and 57.9% and 73.9% at 5 years, respectively. One patient underwent dialysis given a total contralateral nephrectomy due to another RCC 1 month after initial cryoablation and a total ipsilateral nephrectomy 46 months after initial cryoablation due to local progression. Except for two dialysis patients, of the 12 patients with a median follow-up of 41 months (6–93 months), none were on dialysis.

    Conclusion

    Cryoablation was safe and effective in T3a RCC, which mainly involved the renal venous branches and may represent an alternative treatment for inoperable patients.

    PURPOSE: The purpose of this study was to retrospectively determine the incidence of early enlarging cavitation after percutaneous radiofrequency ablation (RFA) of lung tumor and identify risk factors associated with their occurrence. PATIENTS AND METHODS: A total of 245 patients (140 men, 105 women; mean age, 62.7 ± 11.8 [SD] years; age range: 31-87 years) with 605 lung tumors who were treated using 401 RFA sessions from April 2010 to March 2020 were included. Of which, 31 patients with 38 early enlarging cavitation and control group (151 patients with 228 tumors) were analyzed. Early enlarging cavitation was defined as cavities with an enlarged size (>3 cm) occurring on ablated lesions within seven days after RFA. Incidence of cavitation, risk and post-procedural factors of occurrence, major adverse events (AEs) that occurred in RFA sessions with cavitation, and course of cavitation were evaluated. AEs were classified using the CIRSE classification system for complications. RESULTS: Thirty-eight cavities (6.3%, 38/605 tumors) in 31 patients occurred in an average of 3.1 ± 1.7 days (range, 1-7 days) after 32 RFA sessions. Distance from pleura ≥ 20 mm, contact with vessel ≥ 3 mm, multitined expandable electrode ≥ 3 cm, and bronchus ≥ 2 mm encompassed in the ablation zone were independent risk factors of occurrence. Fever ≥ 38.5 °C, white blood cell count ≥ 10,000/μl one day after RFA, and steroid therapy were independent post-procedural factors of occurrence. Twenty-four Grade 3 and two Grade 6 AEs occurred. Twenty-nine cavities disappeared within a mean duration of 111.9 ± 64.9 (SD) days (range: 44-274 days) and four remained with a mean follow-up of 279.2 ± 174 (SD) days; five patients were lost to follow-up. CONCLUSIONS: Early enlarging cavitation occurs in 6.3% of lung tumors treated with RFA and are associated with 26 major AEs in 32 sessions. Aforementioned procedural factors and post-procedural inflammation were significant risk factors of occurrence.

    PURPOSE: To retrospectively evaluate and correlate the contrast-enhanced computed tomography (CECT) and non-enhanced magnetic resonance imaging (MRI) during the early period following renal cryoablation. MATERIALS AND METHODS: Both dynamic CECT and non-enhanced MRI were performed within 4 days following cryoablation in 34 renal tumors in 33 patients. The renal volumes of the unenhanced regions on dynamic CECT (nephrogenic phase, 4 mm thickness) and the regions with signal intensity changes on non-enhanced MRI (fat-suppressed T2-weighted image, 4 mm thickness) were evaluated. Fusion images of the axial, coronal, and sagittal sections of CECT and MRI images were created from the maximum cross-section of the renal tumor, and the match score of each image was visually evaluated on a 5-point scale. RESULTS: The mean renal volume of the unenhanced regions on CECT and those with signal intensity changes on non-enhanced MRI following cryoablation were 29.5 ± 19.9 cm3 (range, 4.3-97.4 cm3) and 30.7 ± 19.8 cm3 (range, 6.7-94.0 cm3), respectively; the difference between them was -1.17 cm3 (95% confidence interval [CI] -2.74, 0.40, P = 0.139). The Pearson's product-moment correlation coefficient (r = 0.975; 95% CI, 0.951, 0.988; P < 0.0001) showed a strong correlation between the volumes. The average match score between CECT and non-enhanced MRI was as high as 4.5 ± 0.5 points (radiologist 1, 4.3 ± 0.5; radiologist 2, 4.7 ± 0.5). Local tumor control rate was 94.1% (32/34 tumors) and recurrence-free survival rate was 82.0% (95% CI: 64.2%, 91.5%) at 5 years. CONCLUSIONS: The region with signal intensity changes on non-enhanced MRI was strongly correlated with the unenhanced region on CECT during the early period following renal cryoablation.

    OBJECTIVES: Renal cell carcinoma (RCC) is often found incidentally in asymptomatic individuals undergoing abdominal computed tomography (CT) examinations. The purpose of our study is to develop a deep learning-based algorithm for fully automated detection of small (≤4 cm) RCCs in contrast-enhanced CT images using a multicenter database and to evaluate its performance. MATERIALS AND METHODS: For the algorithmic detection of RCC, we retrospectively selected contrast-enhanced CT images of patients with histologically confirmed single RCC with a tumor diameter of 4 cm or less between January 2005 and May 2020 from 7 centers in the Japan Medical Image Database. A total of 453 patients from 6 centers were selected as dataset A, and 132 patients from 1 center were selected as dataset B. Dataset A was used for training and internal validation. Dataset B was used only for external validation. Nephrogenic phase images of multiphase CT or single-phase postcontrast CT images were used. Our algorithm consisted of 2-step segmentation models, kidney segmentation and tumor segmentation. For internal validation with dataset A, 10-fold cross-validation was applied. For external validation, the models trained with dataset A were tested on dataset B. The detection performance of the models was evaluated using accuracy, sensitivity, specificity, and the area under the curve (AUC). RESULTS: The mean ± SD diameters of RCCs in dataset A and dataset B were 2.67 ± 0.77 cm and 2.64 ± 0.78 cm, respectively. Our algorithm yielded an accuracy, sensitivity, and specificity of 88.3%, 84.3%, and 92.3%, respectively, with dataset A and 87.5%, 84.8%, and 90.2%, respectively, with dataset B. The AUC of the algorithm with dataset A and dataset B was 0.930 and 0.933, respectively. CONCLUSIONS: The proposed deep learning-based algorithm achieved high accuracy, sensitivity, specificity, and AUC for the detection of small RCCs with both internal and external validations, suggesting that this algorithm could contribute to the early detection of small RCCs.

    Small renal tumors are sometimes challenging to diagnose accurately through imaging alone, and image-guided biopsies are performed when histological diagnoses are needed. Although ultrasound guidance is usually chosen for renal tumor biopsies, computed tomography guidance is preferred for selected cases; e.g., obese patients or when the target is undetectable by ultrasound (as those in the upper pole). In the 14 recently published studies covering ≥50 procedures, computed tomography-guided renal tumor biopsies had a wide range diagnostic yield (67.4%-97.4%). Complications often occurred; however, most were minor and asymptomatic. No biopsy-related deaths and tumor seeding occurred. This study aimed to review the advantages and disadvantages, procedure techniques, diagnostic yields, and complications of core needle biopsies for renal tumors under computed tomography guidance.

    PURPOSE: The purpose of this retrospective study was to determine the incidence of persistent patent artery after percutaneous cryoablation of renal cell carcinoma (RCC) and the relationship between patent arteries one month after cryoablation and early tumor progression. MATERIALS AND METHODS: One hundred and fifty-nine patients (112 men, 47 women; mean age, 63.6±14.6 [SD] years; age range: 21-91 years) who underwent percutaneous cryoablation for 186 RCCs (mean diameter, 1.9±0.6 [SD] cm; range: 0.7-4.0cm) were retrospectively included. After cryoablation, patients underwent contrast-enhanced computed tomography (CT) with ≤2-mm slice thickness within one week from cryoablation, and at one, three, and six months. The time course of patent artery in the ablated renal parenchyma after cryoablation was the primary endpoint. The relationships between patent arteries one month after cryoablation and treatment effectiveness, tumor vascularity, tumor enhancement one month after cryoablation, tumor subtype, and renal function changes were evaluated as secondary endpoints. RESULTS: CT showed patent arteries in the ablated renal parenchyma within one week in 166 RCCs (89.2%), at one month in 54 RCCs (29.0%), at three months in 8 RCCs (4.3%), and at six months in 2 RCCs (1.1%). The presence of patent artery one month after cryoablation was significantly associated with tumor enhancement at the same time point (P=0.015). There was no association between patent arteries one month after cryoablation and treatment effectiveness (P=0.693). CONCLUSION: Patent arteries in the ablated renal parenchyma are commonly observed on CT examination after percutaneous cryoablation of RCC. However, they gradually disappear and do not require specific treatment.

    Percutaneous cryoablation for renal tumors may be associated with rare complications such as injury to the ureter. A 65-year-old woman underwent percutaneous cryoablation after a transcatheter arterial embolization using lipiodol and ethanol for left renal oncocytoma. Two months after the percutaneous cryoablation, computed tomography images showed left hydronephrosis caused by high-density debris, which was assumed to be sloughed tumor with lipiodol accumulation in the left ureter. A stent was placed in the left ureter to enhance the drainage of urine and the necrotic cell debris. Three months later, the ureteral stent was removed, and she remained asymptomatic during the follow-up period of 4 months. We should consider the possibility of urinary tract obstruction by sloughed tumor when hydronephrosis occurs after percutaneous cryoablation of a renal tumor.

    Polycythemia vera (PV) is a chronic myeloproliferative neoplasm that leads to hyperviscosity and the risk of thrombosis. We encountered the case of a young male Filipino patient diagnosed with PV after the rupture of esophageal varices. The complete blood cell count showed a slight increase in white blood cells. An abdominal computed tomography scan disclosed splenomegaly and occlusion of the portal vein and collateral vessels. A blood examination demonstrated an increase in all three blood cell lines within three months. Based on the presence of severe hypercellularity of the bone marrow and positivity for the JAK2V617F mutation, we finally diagnosed the patient with PV.

    We report herein the case of a 76-year-old woman with autosomal dominant polycystic kidney disease (ADPKD) and chronic renal failure resulting in intractable abdominal distension and anorexia. Computed tomography (CT) showed enlarged and cystic kidneys. We performed transcatheter arterial embolization (TAE) for renal arteries with ethanol. Absolute ethanol with iodinated contrast medium or Lipiodol was delivered into both renal arteries. The patient's low-grade fever subsided in 5 days, and no other complication occurred. The sensation of abdominal distension diminished approximately 1 month after embolization. A progressive decrease in kidney size was observed soon after embolization. The percentage of the decrement of kidney size was approximately 50% after 17 months. These results indicate that renal TAE with ethanol is a safe, cost-effective, and minimally invasive technique to reduce kidney size in symptomatic ADPKD patients.

    OBJECTIVE: To evaluate the clinical utility of lung radiofrequency ablation (RFA) in patients with unresectable pulmonary metastasis from renal cell carcinoma (RCC). PATIENTS AND METHODS: We retrospectively examined 39 patients with unresectable metastases from RCC who were treated with lung RFA. Patients with six or fewer lung metastases measuring < or =6 cm that were confined in the lung, had all lung tumours ablated (curative ablation). Patients with extrapulmonary lesions, seven or more lung tumours, or large tumours of >6 cm, had mass reduction (palliative ablation). The primary endpoints was the overall survival, secondary endpoints were safety, local tumour progression rate, and recurrence-free survival in the curative ablation group. RESULTS: There were significant differences in the overall survival rates between the curative and palliative groups at 1 year (100% vs 90%), 3 years (100% vs 52%) and 5 years (100% vs 52%) (P < 0.05). The maximum lung tumour diameter was also a significant prognostic factor. There was local tumour progression in 13 patients (33%) during the mean follow-up of 25 months. The recurrence-free survival rates were 92% at 1 year, 23% at 3 years and 23% at 5 years in the curative ablation group. Pneumothorax requiring chest tube placement (six of 89, 7%) and pneumonia (one of 89, 1%) were major complications. CONCLUSION: Lung RFA is a safe and effective treatment for prolonging survival in patients with unresectable RCC lung metastases.

    The aim of this study is to describe vision loss caused by central retinal artery and posterior ciliary artery occlusion as a consequence of sclerotherapy with a polidocanol injection to a glabellar hemangioma. An 18-year-old man underwent direct injection with a 23-gauge needle of 1 mL of a polidocanol-carbon dioxide emulsion into the glabellar subcutaneous hemangioma under ultrasound visualization of the needle tip by radiologists. He developed lid swelling the next day, and 3 days later at referral, the visual acuity in the left eye was no light perception. Funduscopy revealed central retinal artery occlusion and fluorescein angiography disclosed no perfusion at all in the left fundus, indicating concurrent posterior ciliary artery occlusion. The patient also showed mydriasis, blepharoptosis, and total external ophthalmoplegia on the left side. Magnetic resonance imaging demonstrated the swollen medial rectus muscle. In a month, blepharoptosis and ophthalmoplegia resolved but the visual acuity remained no light perception. Sclerosing therapy for facial hemangioma may develop a severe complication such as permanent visual loss.

    BACKGROUND: The purpose of the study was to retrospectively evaluate the risk factors for local progression after percutaneous radiofrequency (RF) ablation of lung tumors. METHODS: The study included 128 patients (77 men, 51 women; mean age, 61.3 years) with 342 tumors (25 primary and 317 metastatic lung neoplasms; mean long-axis diameter, 1.7 cm) treated with RF ablation. The overall primary and secondary technique effectiveness rates were estimated using Kaplan-Meier analysis. Multiple variables were analyzed using the log-rank test, followed by multivariate multilevel analysis to determine independent risk factors for local progression. The primary and secondary technique effectiveness rates were again estimated when considering only tumors without independent risk factors. RESULTS: The median follow-up period was 12 months (range, 6-47 months). The overall primary and secondary technique effectiveness rates were 72% and 84% at 1 year, 60% and 71% at 2 years, and 58% and 66% at 3 years, respectively. Larger tumor size (hazard ratio [HR], 1.97; 95% confidence interval [95% CI], 1.47-2.65; P < .00001) and the use of an internally cooled electrode (HR, 2.32; 95% CI, 1.10-4.90; P = .027) were assessed as independent risk factors for local progression. The primary and secondary technique effectiveness rates when considering tumors smaller than 2 cm and treated with a multitined expandable electrode were 89% and 89% at 1 year and 66% and 78% at 2 years, respectively. CONCLUSIONS: Larger tumor size and the use of an internally cooled electrode were independent risk factors for local progression after RF ablation of lung tumors.

    We quantitatively evaluated total and individual renal function by technetium-99m mercaptoacetyltriglycine (Tc-99m MAG3) renal scintigraphy before and after radiofrequency ablation (RFA) of renal tumors. Eleven patients who underwent Tc-99m MAG3 renal scintigraphy 1 week before and after RFA were evaluated (7 men and 4 women; age range: 23-83 years; mean age: 60.6 years). Five patients had solitary kidneys, and five had normally or minimally functioning contralateral kidneys. One patient had a renal cell carcinoma in the contralateral kidney. One patient with a solitary kidney underwent RFA a second time for a residual tumor. In patients with a solitary kidney, MAG3 clearance decreased after 5 of 6 RFAs, and in patients with a normally functioning contralateral kidney, MAG3 clearance decreased after 4 of 5 RFAs, but no significant differences were observed between before and after treatments. In addition to the total MAG3 clearance, the split MAG3 clearance was evaluated in patients with a normally functioning contralateral kidney. MAG3 clearance decreased in 4 of 5 treated kidneys, while it adversely increased in the contralateral kidneys after 4 of 5 RFAs. No significant differences, however, were observed between before and after treatments. The results of our study revealed no significant differences in sCr, BUN, CCr, or MAG3 clearance between pre- and post-RFA values. These results support data regarding the functional impact and safety of renal RFA in published reports. We evaluated total and individual renal function quantitatively using Tc-99m MAG3 renal scintigraphy before and after treatment. This scintigraphy was very useful in assessing the effects of RFA on renal function.

    Institutional review board approval and patient informed consent were obtained. Radiofrequency ablation in a total of 10 sessions was performed for each mediastinal lymph node metastasis from esophageal cancer that had a mean largest diameter of 2.2 cm +/- 0.6 (standard deviation) in seven male patients (mean age, 59 years). During ablation, cooling and temperature of the tracheal mucosa were monitored in the proper position in eight of the 10 sessions; in the other two sessions, monitoring was not done because of tracheal stenosis (perforation resulted). Three of the four lymph nodes that were 2.0 cm or smaller in largest diameter showed no evidence of local progression for at least 1 year since ablation; all three of the nodes greater than 2.0 cm in largest diameter progressed within 6 months. The 1-year survival rate was 60%; the median survival time was 13 months. Radiofrequency ablation may be effective for local control of small metastatic mediastinal lymph nodes, and cooling and temperature monitoring of the tracheal mucosa in the proper position may prevent thermal tracheal damage.

    Renovascular hypertension (RVH) is caused from various diseases. Here, we report a case of RVH complicated with ulcerative colitis in a 40-year-old male. The contrast enhanced CT scan and angiography revealed right renal artery occlusion and developed collateral arteries. It also revealed the stenosis of left renal segmental artery and hepatic artery, obstruction of the beginning of both internal iliac arteries, and partial constriction of the abdominal aorta. FDG-PET demonstrated no uptake of FDG in large vessels. Skin and colon biopsies showed no evidence of any vasculitis. Thus, this case was very difficult to diagnose what caused RVH.

    腎癌原発の切除不能肺転移病変に、経皮的にradiofrequency ablation(RFA)を行った。対象は39例で、肺転移部位個数が6個以下、かつ最大径6cm未満のCurative群15例(C群)、肺転移部位個数が7個以上、もしくは最大径6cm以上のPalliative群24例(P群)に分けた。Over all survivalは、1年はC群:100%、P群:90.3%、5年はC群:100%、P群:52.4%で、C群において有意に高かった。RFAを行った病変のlocal progression rateは、C群:2例(13%)、P群:11例(46%)で、risk factorは最大腫瘍径:3cm以上であった。C群におけるrecurrence-free rateは、1年:92.3%、5年:23.2%であった。合併症は、majorなものはC群:15%、P群:5%、minorなものはC群:8%、P群:5%で、2群間に有意差はなかった。経皮的RFAは、腎癌肺転移巣に対する局所治療として有益で、肺病変が6個以下、最大径3cm以下、肺転移以外に転移病巣が確認されていない症例には良い適応だと思われた。

    Primary lung cancer is a worldwide problem, but many patients are non-surgical candidates due to comorbidities. Percutaneous radiofrequency (RF) ablation is a newly developed therapeutic option for unresectable lung cancer. Several authors have reported preliminary and midterm results of this therapy, including its usefulness and minimal invasiveness. However, its technique is not well established. RF ablation for lung cancer has been performed at Okayama University since June 2001 after we obtained approval from our institutional review board. A total of 312 patients with 853 tumors have been treated as of the end of April 2007. Primary and secondary technique effectiveness rate at 3 years is 58% and 66%, respectively. Survival after this therapy seems promising, especially for those patients with unresectable stage-I non small cell lung cancer (NSCLC), with intrapulmonary recurrence after resection of primary NSCLC, and with pulmonary metastases from colorectal cancer. In this paper, we describe the indications, ablation planning, techniques, results, complications, and prospects for the future of this therapy, based on our 6-year experience.<br>

    ラジオ波焼灼療法は、時に、隣接構造物に熱損傷を与える。それを防ぐために気管粘膜の温度モニタリングと冷却を行いながら、食道癌術後の縦隔リンパ節転移に対してラジオ波焼灼療法を施行した。食道癌術後の縦隔リンパ節転移7例を対象とした。リンパ節転移の大きさが2cm以下の4例中3例では、1回もしくは2回の治療により、リンパ節は完全焼灼され、局所再発を認めていない。リンパ節が2cmを超える3例は全て6ヵ月以内に再発した。合併症は、経肺的に電極針を刺入した4セッションのうち2セッションで気胸が生じたが、いずれも無治療で改善した。ホルネル症候群が2例にみられた。気管狭窄のため気管内チューブのカフを腫瘍レベルまで挿入することが出来ず、そのため適切な位置での気管冷却、温度モニタリングが出来なかった2例では、いずれも気管膜様部で穿孔が生じた。

    The use of MRI-guidance for biopsy has several advantages such as no radiation exposure and excellent soft tissue contrast. A high field (1.2T) open MRI system has a suitable design for biopsy procedures and high imaging capability. Thus, a clinical study was conducted to evaluate the feasibility of MRI-guided biopsy using this system. In this study, MRI-guided biopsy was feasible and safe for targets of various locations in 10 patients.

    A prospective clinical study was designed to confirm the safety and efficacy of cryotherapy for painful bone and soft tissue tumors and started after approval of the Okayama University Hospital Ethics Committee. Initially 10 patients were scheduled to be enrolled but only 2 were enrolled. The treatment efficacy was excellent in both cases, and marked pain improvement was observed. Pre-treatment Visual Analogue Scale was 2.0 and 9.0, respectively, and 4 weeks after treatment they reduced 0.8 and 1.3, respectively. Four weeks later, one patient had a complete response without tumor enhancement on MR images. In other case, although tumor enhancement remained slightly, most disappeared. With regard to safety, in both cases, anticipated Grade 4 adverse event occurred, but improved with no treatment and no sequelae. This therapy may be effective and safe for painful bone and soft tissue tumors

    For adding a hook to an absorbable suture, a folded suture make it large in diameter, and a partially-cut suture make it brittle. A barbed suture can bring solutions to those problems. In addition, it is stiff enough to be pushed through a guiding needele by itself. To add radio-opaque nature to it, iodine contrast medium or barium sulfate were laid on it. Those radio-opaque sutures were visible on X-ray fluoroscopy image.
    In a phantom examination, the radiopaque absorbable suture was easily placed near a target through a guiding needle. It was clearly visible on CT image. The barbed suture could not easily pull out from the phantom.
    Therefore, we believe that we can make the guiding marker which is made of the barbed absorbable suture.

    In 2013, a prototype robot was developed and phantom studies were performed. Robot was remotely controlled with controller and a needle was successfully inserted into a target 2 cm in size without radation exposure to a physician. In 2014 and 2015, the prototype robot was improved. In 2014, backlash during motion was improved. More needle insertion strength and faster insertion speed were applied. Usability of interface was also improved, and presentation of force sense to a physician was acheived. In 2015, hand section of the robot was made smaller and lighter. Further, mechanism of needle attachment and removal was simplified.

    進行肝細胞癌に対する標準的治療の確立を目指し、平成27年度は多施設共同前向き臨床試験の実施を行った。ソラフェニブは進行肝細胞癌の生存期間を有意に延長することを示した初めての抗がん剤であり、標準治療として使用されているものの、その予後は生存期間中央値で6.5-10.7ヶ月と十分ではなく、より有用な治療法が求められている。
    肝病変が予後規定因子と考えられる進行度分類(BCLC-stage)C症例に対して、ソラフェニブ療法に肝動脈化学塞栓療法を併用することで、治療成績が向上することを期待し、本臨床試験は、ソラフェニブと肝動脈化学塞栓療法の併用療法の安全性と有効性を目的とした多施設共同第Ⅱ相試験を立案した。適格基準は(1)組織学的あるいは臨床的に診断された肝細胞癌症例、(2)肝切除や局所焼灼療法による治療効果が見込めない症例、(3)進行度分類(BCLC-stage)C(Vp3,4は除く)、肝機能がChild-Pugh score 6点以下、除外基準は(1)治療に反応しない中等度以上の腹水あるいは胸水を有する、(2)肝性脳症を認める、(3)脳転移を認める、(4)重篤な合併症を有する症例とした。本臨床試験のprimary endpointはプロトコール治療完遂割合、Secondary endpointは有害事象発生割合、全生存期間、無増悪生存期間、奏効割合と設定した。24ヶ月の登録期間で32症例の症例登録を予定している。
    現在までに国内13施設が本臨床試験に参加、目標32例のうち2015年6月現在で30例の症例登録があった。症例登録があと数例で登録終了するため。終了次第ソラフェニブと血管塞栓治療による相乗効果の検討の予定であった。予後因子を単変量、多変量解析し適応など検討を予定していました。

    Radiofrequency ablation was performed for pulmonary aspergilloma. The procedure was safely done without any adverse events. Serial follow-up CT scan up to 26 months after the procedure showed that ablation zone continued to shrink. At 16 months, biopsy of the ablation zone was performed and revealed that the specimen was consisted mostly of abundant fibrotic tissue and partly of hypha. Thus, this study showed radiofrequency ablation was safe and effective as a treatment of pulmonary aspergilloma.

    From 2008 to 2010, thirty five tumors in 30 patients that show no local progression for more than 2 years were included in this study. In CT images, the size of ablation zone decreased after 3 or 6 months after radiofrequency ablation (RFA) compared to 1 month after the procedure. On the other hand, the accumulation of FDG in PET scan obtained 3 months after RFA, showed no significant difference compared to the pre-treatment image, but significant decrease after 6 months after the treatment. In conclusion, it is eligible that FDG-PET was performed 6 months than 3 months after RFA.

    Radiofrequency (RF) ablation is a new clinical procedure which has been applied for the treatment of lung malignancies for recent years.
    To improve clinical results, it is very important to enlarge the RF ablation area in the lung. One possible way to enlarge the ablation area is an injection of saline in the lung to improve RF induction. The other way is an artificial obstruction of the pulmonary artery in the ablation area to reduce the blood flow which cools the ablation area. The purpose of our study was to confirm the usefulness of these two interventions by animal experiment.
    Domestic pigs and LeVeen RF electrode with 2cm in diameter and RF 2000 or 3000 Generator system (Radiotherapeutics) were used in this experiment. Living pig's lung was ablated by RF with and without 3m1 of saline injection under the same ablation algorism then the pig was scarified. Macro-and microscopic examinations showed that the volume of the ablated area with saline injection was almost twice as much as that without saline injection and more homogenous ablation was observed with saline injection.
    In the next experiment, pig's lung was ablated with and without pulmonary arterial embolization with degradable starch micro-spheres (DSM) which could temporarily occlude vessels. Macro-and microscopic examinations showed that the volume of the ablated area with embolization was almost twice as much as that without embolization and the lung tissue was not injured by embolization.
    This study revealed the safety and usefulness of saline injection and temporary occlusion of the pulmonary artery when we try to enlarge the ablation area in the lung by RF.
