OBJECTIVES: To clarify the impact of central nervous system (CNS) metastasis on performance status (PS) at relapse, on subsequent treatment(s), and on survival of patients with lung adenocarcinoma harboring common epidermal growth factor receptor (EGFR) mutation. METHODS: We conducted the multicenter real-world database study for patients with radical resections for lung adenocarcinomas between 2015 and 2018 at 21 centers in Japan. EGFR mutational status was examined at each center. RESULTS: Of 4181 patients enrolled, 1431 underwent complete anatomical resection for lung adenocarcinoma harboring common EGFR mutations. Three-hundred-and-twenty patients experienced disease relapse, and 78 (24%) had CNS metastasis. CNS metastasis was significantly more frequent in patients with conventional adjuvant chemotherapy than those without (30% vs. 20%, P = 0.036). Adjuvant chemotherapy did not significantly improve relapse-free survival at any pathological stage (adjusted hazard ratio for stage IA2-3, IB, and II-III was 1.363, 1.287, and 1.004, respectively). CNS metastasis did not affect PS at relapse. Subsequent treatment, mainly consisting of EGFR-tyrosine kinase inhibitors (TKIs), could be equally given in patients with or without CNS metastasis (96% vs. 94%). Overall survival after relapse was equivalent between patients with and without CNS metastasis. CONCLUSION: The efficacy of conventional adjuvant chemotherapy may be limited in patients with lung adenocarcinoma harboring EGFR mutations. CNS metastasis is likely to be found in practice before deterioration in PS, and may have little negative impact on compliance with subsequent EGFR-TKIs and survival after relapse. In this era of adjuvant TKI therapy, further prospective observational studies are desirable to elucidate the optimal management of CNS metastasis.

We summarized the experience of surgical stabilization of rib fractures (SSRF) at a core hospital in eastern Hiroshima, which is a primary center for tertiary emergency medical care, especially for high-energy trauma cases including chest injuries. The study focuses on patients who underwent SSRF from January 2016 to September 2023, analyzing patient characteristics, injury mechanisms, associated injuries, fracture locations, time from injury to surgery, fixation devices used, and postoperative outcomes. Our hospital primarily treats elderly patients, and falls are the most common cause of injury, followed by traffic accidents. The criteria for SSRF in our hospital were clinical manifestations of flail chest, need for lung repair, persistent pain, or improvement of thoracic deformity. We had a high rate of fixation of fractures of the 4th-10th ribs, which have a significant impact on respiratory mechanics; although KANI plates were primarily used, the introduction of MatrixRIB plates offers advantages in certain scenarios. The study also identified challenges with the KANI plate, including cases of plate dislodgement, particularly in patients with multiple fractures and severe thoracic deformities. The combination of video-assisted thoracoscopic surgery and SSRF allows for more effective rib fixation and reduces surgical wound size and muscle damage.

OBJECTIVES: Histidine-rich glycoprotein has been reported as an anti-inflammatory glycoprotein that inhibits acute lung injury in mice with sepsis and as a prognostic biomarker in patients with sepsis. We investigated the relationship between plasma concentrations of histidine-rich glycoprotein and the risk of occurrence of primary graft dysfunction. METHODS: According to the primary graft dysfunction grade at post-transplant 72 hours, patients who underwent lung transplantation were divided into three groups: non-primary graft dysfunction group (grade 0-1), moderate primary graft dysfunction group (grade 2), and severe primary graft dysfunction group (grade 3). The plasma concentrations of histidine-rich glycoprotein measured daily during the first post-transplant 7 days were compared among the three groups. Appropriate cutoff values of the concentrations were set for survival analyses after lung transplantation. RESULTS: A total of 68 patients were included. The plasma histidine-rich glycoprotein concentration at post-transplant 72 hours was significantly lower in the severe primary graft dysfunction group (n = 7) than in the other two groups (non-primary graft dysfunction group (n = 43), P = 0.042; moderate primary graft dysfunction group (n = 18), P = 0.040). Patients with plasma histidine-rich glycoprotein concentration ≥34.4 µg/mL at post-transplant 72 hours had significantly better chronic lung allograft dysfunction-free survival (P = 0.012) and overall survival (P = 0.037) than those with the concentration <34.4 µg/mL. CONCLUSIONS: Plasma histidine-rich glycoprotein concentrations at post-transplant 72 hours might be associated with the risk of development of primary graft dysfunction.

BACKGROUND: No proven treatment after the development of primary graft dysfunction (PGD) is currently available. Here we established a novel strategy of in vivo lung perfusion (IVLP) for the treatment of PGD. IVLP involves the application of an in vivo isolated perfusion circuit to an implanted lung. This study aimed to explore the effectiveness of IVLP versus conventional post-lung transplant (LTx) extracorporeal membrane oxygenation (ECMO) treatment using an experimental swine LTx PGD model. METHODS: After 1.5-h warm ischemia of the donor lungs, a left LTx was performed. Following the confirmation of PGD development, pigs were divided into three groups (n = 5 each): control (no intervention), ECMO, and IVLP. After 2 h of treatment, a 4-h functional assessment was conducted and samples obtained. RESULTS: Significantly better oxygenation were achieved in the IVLP group (p ≤ 0.001). Recovery was confirmed immediately and maintained during the following 4-h observation. The IVLP group also demonstrated better lung compliance than the control group (p = 0.045). A histological evaluation showed that the lung injury score and terminal deoxynucleotidyl transferase dUTP nick end labeling assay showed significantly fewer injuries and a better result in the wet-to-dry weight ratio in the IVLP group. CONCLUSIONS: A two-hour IVLP is technically feasible and allows for prompt recovery from PGD after LTx. The posttransplant short-duration IVLP strategy can complement or overcome the limitations of the current practice for donor assessment and PGD management.

BACKGROUND: The use of extracorporeal membrane oxygenation (ECMO) as a bridge to lung transplantation is an uncommon strategy in Japan owing to the severe donor shortage and absence of urgent allocation policy. Moreover, the use of veno-venous (VV) ECMO for immunosuppressed patients is controversial; thus, applying ECMO to patients who await lung re-transplantation is challenging. CASE PRESENTATION: A 16-year-old lung transplant recipient with grade 3 bronchiolitis obliterans syndrome was waitlisted for lung re-transplantation. Eleven months later, he fell into severe respiratory acidosis with hypercapnia, which were not resolved with mechanical ventilation. VV ECMO was introduced to minimize lung stress and strain. Tracheostomy was additionally performed on day 5 after the start of ECMO, and respiratory condition swiftly improved; hence, the weaning process from VV ECMO began on day 9. Rehabilitation became implementable, and bilateral re-lung transplantation was successfully performed 6 months after the ECMO treatment. No critical complication related to the precedent use of ECMO was noted. CONCLUSIONS: VV ECMO can be a feasible treatment option even for lung transplant candidates awaiting re-transplantation for a prolonged period. Introduction of ECMO and tracheostomy in the early deterioration stage may be crucial to successful subsequent patient management.

PURPOSE: Although the performance lung transplantation (LTx) in the elderly (≥ 60 years) has increased globally, the situation in Japan remains quite different, because the age limit at registration for cadaveric transplantation is 60 years. We investigated the long-term outcomes of LTx in the elderly in Japan. METHODS: This was a single-center retrospective study. We divided the patients into two groups according to age: the younger group (< 60 years; Y group; n = 194) and the elderly group (≥ 60 years; E group; n = 10). We performed three-to-one propensity score matching to compare the long-term survival between the E and Y groups. RESULTS: In the E group, the survival rate was significantly worse (p = 0.003), and single-LTx was more frequent (p = 0.036). There was a significant difference in the indications for LTx between the two groups (p < 0.001). The 5-year survival rate after single-LTx in the E group was significantly lower than that in the Y group (p = 0.006). After propensity score matching, the 5-year survival rates of the two groups were comparable (p = 0.55). However, the 5-year survival rate after single-LTx in the E group was significantly lower than that in the Y group (p = 0.007). CONCLUSION: Elderly patients showed acceptable long-term survival after LTx.

Renal dysfunction is a long-term complication associated with an increased mortality after lung transplantation (LT). We investigated the association of single-nucleotide polymorphisms (SNPs) with the development of renal dysfunction after LT using a Japanese-specific SNP array. First, eligible samples of 34 LT recipients were genotyped using the SNP array and divided into two groups, according to the presence of homozygous and heterozygous combinations of mutant alleles of the 162 renal-related SNPs. To identify candidate SNPs, the renal function tests were compared between the two groups for each SNP. Next, we investigated the association between the candidate SNPs and the time course of changes of the estimated glomerular filtration rate (eGFR) in the 99 recipients until 10 years after the LT. ΔeGFR was defined as the difference between the postoperative and preoperative eGFR values. Eight SNPs were identified as the candidate SNPs in the 34 recipients. Validation analysis of these 8 candidate SNPs in all the 99 recipients showed that three SNPs, namely, rs10277115, rs4690095, and rs792064, were associated with significant changes of the ΔeGFR. Pre-transplant identification of high-risk patients for the development of renal dysfunction after LT based on the presence of these SNPs might contribute to providing personalized medicine.

BACKGROUND: MicroRNAs (miRNAs) involved in the pathogenesis of pulmonary fibrosis have been shown to be associated with the development of chronic lung allograft dysfunction (CLAD) after lung transplantation (LT). We investigated the role of circulating miRNAs in the diagnosis of CLAD after bilateral LT, including cadaveric LT (CLT) and living-donor lobar LT (LDLLT). METHODS: The subjects of this retrospective study were 37 recipients of bilateral CLT (n = 23) and LDLLT (n = 14), and they were divided into a non-CLAD group (n = 24) and a CLAD group (n = 13). The plasma miRNA levels of the two groups were compared, and correlations between their miRNAs levels and percent baseline forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), and total lung capacity (TLC) values were calculated from one year before to one year after the diagnosis of CLAD. RESULTS: The plasma levels of both miR-21 and miR-155 at the time of the diagnosis of CLAD were significantly higher in the CLAD group than in the non-CLAD group (miR-21, P = 0.0013; miR-155, P = 0.042). The miR-21 levels were significantly correlated with the percent baseline FEV1, FVC, and TLC value of one year before and at the time of diagnosis of CLAD (P < 0.05). A receiver operating characteristic curve analysis of the performance of miR-21 levels in the diagnosis of CLAD yielded an area under the curve of 0.89. CONCLUSION: Circulating miR-21 appears to be of potential value in diagnosing CLAD after bilateral LT.

OBJECTIVE: The prognostic nutrition index (PNI), calculated using serum albumin and total lymphocyte count, is a recent topical index related to inflammation. Preoperative PNI is regarded as a new preoperative prognostic score in lung transplantation (LTx). This study aimed to investigate the impact of PNI at the time of registration as a prognostic parameter of mortality on the waiting list for LTx. METHODS: A retrospective review was conducted on the data of 132 adult patients registered for LTx in our department between January 2013 and June 2020. Patients who finally received LTx were analyzed as censored data. The overall survival was evaluated using the Kaplan-Meier method for pre-registered clinical factors including the PNI at the time of registration. Overall survival was calculated from the date of listing to the Japan Organ Transplant Network to the date of death. RESULTS: The low-PNI group had a significantly worse prognosis. Multivariate analysis demonstrated that age (p = 0.023), idiopathic interstitial pneumonia (p < 0.001), lung allocation score (LAS) (p < 0.001), and PNI (p < 0.001) were independent prognostic factors for waitlist mortality. CONCLUSIONS: PNI at the time of registration can be an independent prognostic parameter in registered candidates for LTx.

BACKGROUND: Soft-tissue sarcomas are rare malignancies that consist of many different histologic subtypes and arise in various locations in the body. In patients with lung metastases from retroperitoneal sarcomas, the long-term outcomes and prognostic factors are unknown. This study is a retrospective review of patients undergoing pulmonary metastasectomy for retroperitoneal sarcoma metastases at one institution, with the purpose of determining prognostic factors and clinical outcomes. METHODS: This is a single-center, retrospective cohort study of patients undergoing pulmonary metastasectomy for lung metastases from various sarcomas at Okayama University Hospital from January 2006 to December 2018. The Kaplan-Meier method and log-rank test were used for the analyses, and cut-off values of continuous variables were determined by a receiver operating characteristic curve analysis. RESULTS: Twenty-four patients underwent the first pulmonary metastasectomy for lung metastases from retroperitoneal sarcoma in our hospital. Leiomyosarcoma was the most common histologic subtype of retroperitoneal sarcoma (79.2%, n = 19). Median overall survival was 49.9 months, and the 3-year and 5-year survival rates after the first pulmonary metastasectomy were 62.5% and 26.4% respectively. In univariate analysis, age ≥56 years, disease-free interval < 15 months, and size of metastasis (≥ 27 mm) were associated with poor survival. CONCLUSION: Pulmonary metastasectomy can be considered as an effective management strategy in retroperitoneal sarcoma patients with lung metastases in appropriately selected cases, just as it is for other sarcomas.

Hyperimmunoglobulin E syndrome (HIES) is one of the primary immunodeficiencies characterized by recurrent staphylococcal skin and lung infections that result in lung destruction and critically diminished pulmonary function. Despite the lack of definitive treatment, there have been no reports of successful lung transplantation for HIES patients. We report the case of a 42-year-old woman with HIES with progressive bronchiectasis whose pulmonary infection was controlled before transplantation, and subsequent lung transplantation was uneventful. Lung transplantation may be feasible in HIES if the patient is immunologically stable preoperatively and perioperative infections, especially Aspergillus infections, are well controlled.

PURPOSE: Post-transplant lymphoproliferative disorder (PTLD) is a major complication of lung transplantation (LTx). However, few studies on PTLD in Asian populations have been reported. We explored the characteristics of Japanese PTLD cases after LTx. METHODS: We retrospectively reviewed 195 cases of LTx at our institute. We summarized the clinical experiences of 7 PTLD cases and analyzed the patient characteristics and survival outcomes of patients with (n = 7) and without (n = 188) PTLD. RESULTS: All PTLD patients were taking corticosteroids preoperatively (p = 0.0030), and the duration of preoperative corticosteroid therapy was significantly longer in the PTLD group (p = 0.0064) than in the non-PTLD group. The overall survival after LTx was significantly worse in the PTLD group (p = 0.027) than in the non-PLTD group. Among the three patients who died within 1 year after the PTLD onset, two died of opportunistic infections without residual PTLD lesions. Chronic lung allograft dysfunction (CLAD) or bronchiolitis obliterans at an autopsy were diagnosed after PTLD treatment in four cases. CONCLUSIONS: Long-term preoperative corticosteroid therapy may be a risk factor for PTLD after LTx. Opportunistic infections are lethal complications of PTLD, regardless of the effectiveness of PTLD treatment. CLAD occurs at a high rate after PTLD treatment, and close monitoring is required.

OBJECTIVES: We herein review the outcomes of paediatric lung transplantation (LTx) and analyse subgroups divided by age. METHODS: We retrospectively reviewed 43 consecutive paediatric LTx recipients (< 18 years old: cadaveric LTx [n = 9], living-donor lobar LTx [n = 34]). We also analysed subgroups of patients 1-6 years old (n = 10) and 7-17 years old (n = 33). RESULTS: The 1-, 5- and 10-year overall survival (OS) rates in paediatric recipients were 93%, 82% and 67%, respectively. The 1-, 5- and 10-year graft dysfunction (GD)-free survival rates in paediatric recipients were 85%, 59% and 31%, respectively. The 1- and 5-year OS in the 1- to 6-year-old vs. 7- to 17-year-old groups were 70% vs. 100% and 48% vs. 93%, respectively (p < 0.0001). The 1- and 5-year GD-free survival rates in the 1- to 6-year-old vs. 7- to 17-year-old groups were 60% vs. 93% and 24% vs. 69%, respectively (p = 0.024). The 1- to 6-year-old group showed higher rates of non-standard LTx (p = 0.0001), interstitial pneumonia (p = 0.004) and ventilator dependency (p = 0.007) than the 7- to 17-year-old group. CONCLUSION: Paediatric recipients under 7 years old seemed to have a higher risk of mortality and GD than those 7 years old and older.

Lung transplant recipients are often complicated by immunosuppressant-induced nephropathy, which may require renal replacement therapy. We report a case of unilateral lung edema and pulmonary hypertension due to arteriovenous fistula placement in a patient with unilateral chronic lung allograft dysfunction after bilateral living-donor lobar lung transplantation. Lung transplant recipients with limited residual vascular beds, such as lobar graft or severe deviation in lung perfusion, are vulnerable to the acute increase in blood flow due to arteriovenous fistula placement and can easily develop pulmonary edema regardless of the left ventricular function. Hence, careful volume control is required.

OBJECTIVES: Currently, inhaled nitric oxide (NO) therapy for lung transplantation is not covered by public health insurance in Japan. In this study, we evaluated the perioperative use and safety of inhaled NO therapy for lung transplantation. METHODS: Data regarding the duration of treatment and adverse events of inhaled NO therapy were collected for all lung transplantations performed from January 1, 2015, to December 31, 2019, at nine lung transplant facilities in Japan. RESULTS: During the study period, lung transplants were performed in 357 patients, among whom inhaled NO therapy was administered to 349 patients (98%). The median initial and median maximum inhaled NO doses were 10 and 20 ppm, respectively. Inhaled NO therapy was introduced during surgery and continued postoperatively in 313 patients (90%) for a median of 4 days. Significant improvements in oxygenation and decreases in pulmonary arterial pressure were observed in patients receiving inhaled NO therapy. Side effects of inhaled NO therapy, such as methemoglobinemia, were observed in 15 patients (4%), with a significant incidence in patients aged < 18 years. CONCLUSIONS: Inhaled NO therapy was performed in almost all patients who underwent lung transplantation in Japan and showed reasonable efficacy. Therefore, public health insurance coverage for inhaled NO therapy during lung transplantation is recommended.

BACKGROUND: Idiopathic multicentric Castleman disease (iMCD) is a rare polyclonal lymphoproliferative disease caused by the overrepresentation of interleukin-6 (IL-6). Tocilizumab (TCZ) is a humanized monoclonal antibody that binds to the IL-6 receptor and is approved for the treatment of iMCD. The efficacy and tolerability of TCZ in patients with iMCD undergoing lung transplantation (LTx) remain unknown. CASE PRESENTATION: We present the case of a 48-year-old iMCD patient with end-stage lung disease (ESLD) who was successfully treated with cadaveric single-LTx. Intravenous TCZ was used to stabilize the iMCD patient every 2 weeks, except for withdrawal immediately after LTx. At 32 month post-transplant, the patient remained asymptomatic without evidence of rejection, development of de novo donor-specific antibody (DSA), and recurrent iMCD in the native lung. CONCLUSIONS: Single-LTx can be a feasible treatment option for ESLD caused by iMCD. TCZ can be used safely and may be beneficial in recipients with iMCD, and TCZ in combination with usual immunosuppression can be helpful in stabilizing iMCD patients pre- and post-LTx.

PURPOSE: The number of elderly patients who undergo surgery is increasing, even though they are at a high risk due to a decreased physical strength. Furthermore, sarcopenia is generally associated with a poor prognosis in patients with non-small cell lung cancer (NSCLC). METHODS: This study included NSCLC patients  ≥ 65 years old who underwent pulmonary resection in our hospital between 2012 and 2015. Sarcopenia was assessed using the psoas muscle mass index based on computed tomography at the level of the third lumbar vertebra. We elucidated the impact of sarcopenia on short- and long-term outcomes after surgery. RESULTS: We enrolled 259 patients, including 179 with sarcopenia. Patients with sarcopenia before surgery tended to have postoperative complications (p = 0.0521), although they did not show a poor prognosis. In patients with sarcopenia, a multivariate analysis revealed that postoperative complications and the progression of sarcopenia 1 year after surgery were significant risk factors for a poor prognosis (p = 0.0169 and 0.00370, respectively). CONCLUSIONS: The progression of sarcopenia after surgery is associated with a poor prognosis in elderly NSCLC patients with sarcopenia. A strategy to prevent postoperative progressive sarcopenia may be necessary for improving the clinical outcome of this population.

Bronchopleural fistula (BPF) is a severe complication following lung resection. We present the case of a patient with a history of advanced lung cancer, who had undergone induction chemoradiotherapy followed by right middle and lower lobectomy, and who developed BPF after completion right pneumonectomy. Although we had covered the bronchial stump with an omental pedicled flap, BPF was found on postoperative day 19. We covered the fistula with n-butyl-2-cyanoacrylate (NBCA) using bronchoscopy. Although we had to repeat the NBCA treatment, we ultimately cured the patient's BPF and no recurrence was observed up to 15.2 months after surgery.

Although chronic kidney disease (CKD) commonly develops after lung transplantation (LT), living-donor kid-ney transplantation (LDKT) for CKD after LT is known to provide favorable outcomes. We describe the long-term follow-up findings of a patient who underwent LDKT after bilateral cadaveric LT. A 37-year-old male underwent LDKT for CKD 18 years after receiving bilateral cadaveric LT. He developed chronic lung allograft dysfunction (CLAD) 20 years after the LT; however, at 26 years after the initial LT, he is still alive with no pro-gression of CLAD or CKD. KT could be a viable option for CKD even after LT in Japan.

Chest wall resection is traditionally performed via open thoracotomy, a procedure that increases surgical morbidity and reduces postoperative quality of life. Conversely, thoracoscopic chest wall resection may minimize invasiveness but the optimal procedure remains uncertain. We previously reported rib resection using a pneumatic high-speed power drill during video-assisted thoracoscopic surgery for selected lung cancer patients. In this report, we present two cases of chest wall tumor resected using the drill via the thoracoscopic approach. We also report thoracoscopic chest wall reconstruction in one patient using a patch sheet.

OBJECTIVE: We retrospectively investigated the possibility that the 6-min walk test (6MWT) could predict surgical outcomes in lung cancer patients with decreased predicted postoperative (ppo) lung function. METHODS: Patients were enrolled based on their preoperative spirometry: <60% of the ppo forced expiratory volume in 1 s (FEV1.0) or < 60% of the ppo lung carbon monoxide diffusion capacity (DLco). Morbidity, oxygen inhalation required > 10 days, home oxygen therapy (HOT) requirement, unexpected readmission within 90 days, and 90-day mortality were included as surgical outcomes. The correlations with walking distance and the minimum SpO2 (SpO2min) and maximum decrease in SpO2 (ΔSpO2) during the 6MWT were analyzed using logistic regression analysis, adjusting for age, sex, and surgical procedure. RESULTS: Altogether, 121 patients were analyzed. Logistic regression analysis revealed that higher ΔSpO2 and lower SpO2min were significantly correlated with a higher risk of prolonged need for oxygen inhalation and HOT, surgical morbidity, and 90-day mortality. Cut-off values of > 4% for ΔSpO2 were significant for prolonged oxygen inhalation and surgical morbidity. Cut-off values of < 89-91% for SpO2min were also significant for the need for prolonged oxygen inhalation, surgical morbidity, and HOT requirement. There were no significant correlations between walking distance and each surgical outcome. CONCLUSIONS: Oxygen desaturation during 6MWT was a good predictor for poor surgical outcomes in lung cancer patients with decreased ppo pulmonary function.

Thoracoscopic partial pulmonary resection for small peripheral nodules without using a stapler has been introduced to our hospital. After partial resection was performed with electrocautery, two different methods of surface sealing were used: a coagulation method (C method) with Soft Coagulation alone, and a coagulation-suturing method (CS method) with Soft Coagulation combined with continuous suturing. The clinical outcomes of the two methods were retrospectively compared in this study. The C method was used in 19 lesions of 18 cases, and the CS method was used in 20 lesions of 19 cases. Primary lung cancer was the most frequent diagnosis (22 lesions of 21 cases). There were no differences between the two groups in the size and depth of the lesions. Operative time was longer with the CS method than with the C method. Postoperative air leakage was a complication in 4 cases with the C method, and one of them required re-do surgery, whereas only one case with the CS method had temporary air leakage. Postoperative computed tomography showed cavitation in 3 C method cases and 5 CS method cases, all without related symptoms. There were no local recurrences at resected sites. In conclusion, the C method was technically easy to perform, but air leakage may be prolonged after surgery. The CS method may have the advantage of causing less air leakage than the C method, but mastering the technique is important to shorten operative time.

【背景】日本における高齢者レシピエントの長期成績に関しての報告は少ない．今回当院における高齢者レシピエントの長期成績について後方視的に検討した.【対象と方法】1998年1月～2020年1月に施行した18歳以上の肺移植症例161例を対象とした.60歳以上の高齢群(H群：n=10)と18-59歳の非高齢群(L群:n=151)の2群に分けて,全生存期間(OS)およびCLAD発症までの期間(CFS)について解析を行った.【結果】H群ではL群と比較して片肺移植(p=0.03),間質性肺炎(p=0.02),男性(p=0.04)の割合が有意に多かった.BMI,ドナー年齢,総虚血時間,LASスコアには有意差は認めなかった.H群とL群の5年OSはそれぞれ51.9%と75.5%であり,有意差を認めた(p=0.02).H群とL群の5年CFSはそれぞれ53.3%と72.5%であった.サブグループ解析では，H群の片肺移植症例(5年:OS 25%)は両肺移植症例(5年OS:75%)と比較してOSが悪い傾向にあった(p=0.08)が，H群の両肺移植症例はL群の両肺移植症例(5年OS:74.2%)と比較しても同等の成績であった（p=0.5）.【結語】60歳以上のレシピエントの成績は60歳未満と比較し不良だが，両肺移植がより望ましい可能性が示唆された.

【背景】低侵襲に血液や体液を採取し解析を行うLiquid biopsyは、癌領域では既に臨床応用され治療方針の決定に一役買っているが、移植領域ではまだ発展途上である。当科では肺移植におけるLiquid biopsyとして、ドナー由来血中遊離DNA（dd-cf-DNA）とマイクロRNA（miRNA）を標的にした研究を行ってきたため、その成果を報告する。【方法】ドナーとレシピエントの一塩基多型を比較してdd-cf-DNAを測定し、生体肺移植後の急性拒絶反応（AR）における診断的意義を検討した。次にレシピエントのみの検体で評価できるmiRNAを測定し、脳死・生体肺移植後の移植片慢性機能不全（CLAD）における診断的意義を検討した。【結果】dd-cf-DNAは、感染群（p=0.028）や安定群（p=0.001）よりAR群で有意に増加しており、生体肺移植後ARの診断に有用であった（Sci Rep 2018）。また線維化に関与するmiRNAが、非CLAD群よりCLAD群で有意に増加しており（p=0.008）、一秒量の変化率とも相関し（p=0.014）、CLAD診断に有用であった。【結論】肺移植のLiquid biopsy として、dd-cf-DNAは生体肺移植後ARの診断に、またmiRNAはCLADの診断に有用である。今後の臨床応用を目指して症例数の集積と簡便で精度の高い方法の開発が望まれる。
