Objective. The University Hospital Medical Information Network (UMIN)-Clinical Trials Registry (CTR) is a unique web-based registry of clinical trials in Japan. Clinical trials must be registered to a public database when submitting to medical journals. We evaluated the current status of the publication of Japanese lung cancer clinical trials using the UMIN-CTR. Methods. We searched for trials that had been registered to the UMIN-CTR before October 2005 to identify publications associated with the trial results in the UMIN-CTR database. Forty-eight trials concerning lung cancer treatment were found. A final search for publications was performed using the PubMed and UMIN-CTR databases on December 2014. Results. Thirty-one (64.6%) trials were published. Among them, 16 showed positive results concerning primary endpoints and 15 had negative ones. There was no significant difference in publication rates according to the number of participants (≥100 and <100). The studies in which a planned final analysis date in the UMIN-CTR was described by an investigator were significantly more frequently published than those without this description (84.2% vs 51.4%, p=0.021). Conclusion. Approximately two-thirds of trials including negative trials have been published. The UMIN-CTR serves a function as the Japanese clinical trial registry.

PURPOSE: Early administration of both epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) monotherapy and cytotoxic chemotherapy is crucial for non-small cell lung cancer (NSCLC) patients harboring EGFR mutations. We investigated the effect of first-line administration of these therapies on subsequent therapy in NSCLC patients. METHODS: This study enrolled 63 consecutive patients with advanced EGFR-mutant NSCLC and good performance status (PS) and who underwent first-line EGFR-TKI therapy or standard cytotoxic chemotherapy and then had progressive disease, from 2007 to 2011. The ability of each patient to receive the other therapy after first-line treatment failure was assessed. RESULTS: In the first-line setting, 23 and 40 patients received EGFR-TKI therapy and cytotoxic chemotherapy, respectively. At relapse, the EGFR-TKI therapy group showed more frequent PS deterioration (p = 0.042) and greater likelihood of symptomatic central nervous system (CNS) relapse (p = 0.093) compared with the cytotoxic chemotherapy group. Nine (39 %) of 23 patients initially receiving EGFR-TKI therapy could not receive standard cytotoxic therapy after progression mainly due to symptomatic CNS relapse. Only one (3 %) of 40 initially treated with cytotoxic chemotherapy failed to receive subsequent EGFR-TKI therapy (p < 0.001). Multivariate analysis revealed a correlation between the first-line therapy and the failure to switch to the other therapy after disease progression (OR 48.605, p = 0.005). CONCLUSION: In this study, patients who could not receive both EGFR-TKI therapy and cytotoxic chemotherapy in the early-line setting were included more in the first-line EGFR-TKI group, suggesting a potential risk associated with missing the timing of administration of subsequent therapy. Further investigation is warranted to detect their pretreatment clinical or molecular characteristics for development of a new treatment strategy specific for such subpopulation.

To study epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) resistance mechanisms, we established a novel gefitinib-resistant lung cancer cell line derived from an EGFR-mutant non-small cell lung cancer cell line (PC-9) pretreated with 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (designated PC9-GR). We found that gefitinib substantially suppressed the EGFR signaling pathway, whereas ERK was reactivated after several hours in PC9-GR but not in PC-9. The combination of gefitinib with ERK inhibition (by U0126) restored gefitinib susceptibility in PC9-GR, but PI3K-Akt inhibition with LY294002 did not. Although the levels of phosphorylated Src were up-regulated simultaneously with ERK reactivation, neither ERK suppression using U0126 nor an ERK-specific siRNA induced Src phosphorylation. Furthermore, dual inhibition of EGFR and Src restored gefitinib sensitivity in PC9-GR in vitro and in vivo. In conclusion, our results indicate that Src-mediated ERK reactivation may play a role in a novel gefitinib resistance mechanism, and that the combined use of gefitinib with a Src inhibitor may be a potent strategy to overcome this resistance.

We herein report the case of a 68-year-old man diagnosed with invasive mucinous adenocarcinoma of the lungs. Chest computed tomography showed subpleural ground-glass opacity and small nodules with cavitation. A culture of the bronchoalveolar lavage fluid resulted in the detection of Mycobacterium fortuitum. The patient's lung consolidation rapidly progressed; however, repeated bronchoscopy showed no atypical cells, thus suggesting a diagnosis of organizing pneumonia associated with M. fortuitum infection. However, the surgical biopsy specimen was diagnostic for adenocarcinoma, with no mycobacterial infection. Invasive mucinous adenocarcinoma should not be excluded in the differential diagnosis of patients with clinical features of organizing pneumonia and nontuberculous mycobacterium infection, even if a transbronchial biopsy confirms the absence of malignancy.

Gefitinib is an essential drug for the treatment of non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) gene mutations. The approved dosage is 250 mg/body/day without adjustment for physical size such as body surface area (BSA), and the impact of physical size on the efficacy of gefitinib has not been evaluated. Here, we sought to clarify this issue using a retrospective cohort. We reviewed the medical records of patients with consecutive advanced NSCLC harboring EGFR mutations who underwent gefitinib monotherapy at Okayama University Hospital. In total, 101 patients were included in this study, and the median BSA in this cohort was 1.5 m(2). The median progression-free survival (PFS) of the patients with higher BSA (≥1.5 m(2)) was significantly worse than that of those with lower BSA (< 1.5 m(2)) (10.4 vs. 18.0 months; p = 0.019, log-rank test). Multivariate analysis also showed a significant impact of BSA on PFS (hazards ratio, 2.34; 95% confidence interval, 1.78-2.89; p = 0.002). By contrast, no significant association between BSA and PFS was observed in those undergoing cytotoxic chemotherapy (4.0 vs. 5.1 months; p = 0.989, log-rank test), suggesting that BSA is a predictive, rather than a prognostic, marker for gefitinib therapy in EGFR-mutated NSCLC. In conclusion, BSA affected PFS in patients with EGFR-mutated NSCLC who underwent gefitinib monotherapy, suggesting the need for appraisal of BSA-based dose adjustment, even for this molecular target-based therapy.

PARP enzyme plays a key role in the cellular machinery responsible for DNA damage repair. PTEN is a tumorsuppressor gene deactivating PI3K downstreamofEGFR signaling.Wehypothesize that PTEN-deficient lung cancer cells suppressed DNA damage signaling and that the absence of PTEN can sensitize these cells to a concurrent treatment of aDNA-damaging agent (cisplatin) and a PARP inhibitor (olaparib). To investigate the effect of olaparib and cisplatin on PTEN-deficient lung tumors, two EGFR-mutant (deletion in exon19) non-small cell lung cancer (NSCLC) cell lines, PC-9 (PTENwild-type) and H1650 (PTEN loss), were used. We transfected intact PTEN gene into H1650 cells (H1650PTEN+) and knocked down PTEN expression in the PC-9 cells (PC-9PTEN-) using short hairpin RNA (shRNA). Combination of cisplatin with olaparib showed a synergistic effect in vitro according to the combination index in H1650 cells. Restoration of PTEN in the H1650 cells decreased sensitivity to the combination. Ablation of PTEN in PC-9 cells increased sensitivity to olaparib and cisplatin. We also examined the effectiveness of cisplatin and olaparib in a xenograft model using H1650 and PC-9PTEN- cells. The combination of cisplatin with olaparib was more effective than each agent individually. This effect was not observed in a xenograft model using H1650PTEN+ and PC-9 cells. Mechanistic investigations revealed that PTEN deficiency caused reductions in nuclear RAD51 and RPA focus formation and phosphorylated Chk1 and Mre11. Thus, genetic inactivation of PTEN led to the suppression of DNA repair. Mol Cancer Res

BACKGROUND: We examined how crossover therapy might affect the association between progression-free survival (PFS) and overall survival (OS) in non-small cell lung cancer (NSCLC). METHODS: We extracted PFS- and OS-hazard ratios (HRs) in phase III trials of molecular-targeted agents for advanced NSCLC. Their relationship was modeled in a linear function with the coefficient of determination (R-squared) to assess the correlation between PFS and OS. RESULTS: Thirty-four trials with 35 pairs for the investigational and reference arms were identified (24,158 patients). Overall, there was little correlation between PFS- and OS-HRs (R-squared = 0.14), suggesting PFS-HR could account only for 14% of variation in OS-HR. The median proportion of crossover therapy per trial was 20%. If patients seldom crossed over (none or <1%), the association between PFS- and OS-HRs was strong (R-squared = 0.69). When the proportion of crossover was ≥1%, however, R-squared declined considerably (≥1% to <20% crossover, R-squared = 0.27; ≥20% to <40%, R-squared = 0.06; and ≥40%, R-squared = 0.27). CONCLUSIONS: A PFS advantage seldom is associated with an OS advantage any longer. Our analysis suggests this is due to a high level of crossover now that an increasing number of active agents are available for NSCLC.

A 32-year-old male with CATCH22 syndrome presented with a high fever and productive cough after taking drugs for acute bronchitis, including (L)-carbocisteine. Chest radiography revealed ground-glass opacities in the bilateral lung fields. He had a history of similar pneumonia. Under the assumption of drug-induced pneumonia, or bacterial or viral pneumonia, all drugs including (L)-carbocisteine were discontinued, and antibiotics were started. A drug-induced lymphocyte stimulation test was positive only for (L)-carbocisteine. The only drug in common between this and the previous episode of pneumonia was (L)-carbocisteine. We thus concluded that this was a definite case of (L)-carbocisteine-induced pneumonia in a patient with CATCH22 syndrome.

BACKGROUND: The survival advantage achieved by existing anti-cancer agents as second-line therapy for relapsed non-small cell lung cancer (NSCLC) is modest and further improvement of treatment outcome is desired. Combination chemotherapy with irinotecan and amrubicin for advanced NSCLC has not been fully evaluated. METHODS: The primary endpoint of this phase II clinical trial was objective response. Patients with NSCLC who had been treated previously with one or two chemotherapy agents were enrolled. Irinotecan and amrubicin were both administered on Days 1 and 8 of a 21-day cycle, at doses of 100 mg/m(2) and 40 mg/m(2), respectively. RESULTS: Between 2004 and 2006, 31 patients received a total of 101 courses; the median number of courses administered was three (range, one to six). Objective response was obtained in nine of the 31 patients (29.0% response rate; 95% confidence interval (CI), 12.1-46.0%). With a median follow-up time of 43.9 months, median survival time and the median progression-free survival time were 14.2 and 4.0 months, respectively. Myelosuppression was the most frequently observed adverse event, with grade 3/4 neutropenia in 51% of patients. Febrile neutropenia developed after nine courses (9%) and resulted in one treatment-related death. Cardiac toxicity and diarrhea, possibly specific for both agents, were infrequent and manageable. CONCLUSION: Combination chemotherapy with irinotecan and amrubicin is effective in patients with NSCLC but showed moderate toxicities in second- or third-line settings.

INTRODUCTION: Treatment-related death (TRD) remains a serious problem in small-cell lung cancer (SCLC), despite recent improvements in supportive care. However, few studies have formally assessed time trends in the proportion of TRD over the past two decades. The aim of this study was to determine the frequency and pattern of TRD over time. METHODS: We examined phase 3 trials conducted between 1990 and 2010 to address the role of systemic treatment for SCLC. The time trend was assessed using linear regression analysis. RESULTS: In total, 97 trials including nearly 25,000 enrolled patients were analyzed. The overall TRD proportion was 2.95%. Regarding the time trend, while it was not statistically significant, it tended to decrease, with a 0.138% decrease per year and 2.76% decrease per two decades. The most common cause of death was febrile neutropenia without any significant time trend in its incidence over the years examined (p = 0.139). However, deaths due to febrile neutropenia as well as all causes in patients treated with non-platinum chemotherapy increased significantly (p = 0.033). CONCLUSIONS: The overall TRD rate has been low, but not negligible, in phase III trials for SCLC over the past two decades.

BACKGROUND: Heavily treated Wilms' tumor responding to the combination of paclitaxel and carboplatin has not yet been reported. CASE REPORT: A 17-year-old man presented with hematuria. He received a diagnosis of Wilms' tumor with multiple lung metastases and was treated with preoperative chemotherapy including vincristine, dactinomycin, and doxorubicin, a right nephrectomy, and adjuvant chemotherapy, followed by pulmonary metastasectomy. During the next 8 years, he suffered from 4 relapses and has been treated with multiple anticancer agents including high-dose chemotherapy with autologous peripheral blood stem cell transplantation. Finally, the disease progressed due to peritoneal and pleural metastases. With opioid administration for left shoulder pain due to pleural metastasis, he received combination chemotherapy with carboplatin (area under the curve = 4) and paclitaxel (175 mg/m(2)) on day 1. After 2 cycles, he achieved a partial response with mild toxicity. He received 7 cycles of the chemotherapy and the time to progression was 200 days. CONCLUSION: In a refractory case after intensive treatments, we succeeded to control the disease for a while.
