Thymic large cell neuroendocrine carcinomas (LCNECs) are rare, and the optimal regimen for second and subsequent lines of chemotherapy for the treatment of LCNECs remains unknown. In the present case ...study, a 59-year-old male with post-operative recurrent thymic LCNEC was treated with nab-paclitaxel and carboplatin every 4 weeks as third-line chemotherapy, and a partial response was achieved following 4 cycles of this regimen. The patient developed grade 4 neutropenia and grade 3 leukopenia, but none of the other toxicities, including peripheral neuropathy, were severe. Therefore, the patient was able to tolerate this salvage chemotherapy. To the best of our knowledge, the present study is the first case demonstrating clinically meaningful antitumor activity by combination chemotherapy with carboplatin and nab-paclitaxel, resulting in a positive response in a patient with thymic LCNEC.

Small-molecule tyrosine kinase inhibitors (TKIs) targeting the epidermal growth factor receptor (EGFR) pathways are used clinically for patients with non-small cell lung cancer (NSCLC). It is well ...established that somatic mutations in the kinase domain of the EGFR (Lynch et al. in N Engl J Med 350:2129-2139, 2004; Paez et al. in Science 304:1497-1500, 2004) are strongly associated with the tumor response and clinical outcomes in patients with NSCLC receiving EGFR-TKIs (Mitsudomi and Yatabe in Cancer Sci 98:1817-1824, 2007). Although the most common adverse events are skin rash and diarrhea, the most serious adverse effect reported is drug-related interstitial lung disease (ILD) (Inoue et al. in Lancet 361:137-139, 2003; Ando et al. in J Clin Oncol 24:2549-2556, 2006). The precise mechanism underlying the development of drug-related ILD remains unknown. Here, we describe a case of EGFR-mutant NSCLC who was rechallenged with the small-molecule EGFR antagonist erlotinib after developing gefitinib-related ILD.

Background: Pemetrexed monotherapy has come to be recognized as one of the standard second-line therapies for advanced non-squamous non-small cell lung cancer (NSCLC). However, there have been no ...reports of studies that have evaluated the efficacy of pemetrexed according to type of active EGFR mutation, i.e., an exon 19 deletion or an L858R point mutation. Materials and Methods: The records of non-squamous NSCLC patients harboring an EGFR mutation who received pemetrexed monotherapy as a second or later line of chemotherapy at Kitasato University Hospital between March 2010 and October 2015 were retrospectively reviewed, and the treatment outcomes were evaluated. Results: The overall response rate and progression-free survival time (PFS) of the 53 patients with non-squamous NSCLC were 15.1% and 2.3 months, respectively. There were significant differences between the disease control rate (37.5% vs. 76.2%) and PFS time (1.8 months vs. 3.3 months) of the exon 19 deletion group and the L858R point mutation group, and a multivariate analysis identified type of EGFR mutation as well as performance status (PS) as independent predictors of PFS. Conclusions: The clinical data obtained in this study provided a valuable rationale for considering type of EGFR mutation as well as non-squamous histology as predictors of the efficacy of pemetrexed monotherapy.
The purpose of this study was to evaluate the efficacy of pemetrexed monotherapy in previously treated patients with advanced non-small cell lung cancer (NSCLC) including salvage treatment, and to ...evaluate whether thymidylate synthase (TS) expression is a predictor for pemetrexed efficacy. Hundred and four previously treated patients with advanced NSCLC who received pemetrexed monotherapy were retrospectively evaluated for clinical efficacy and toxicity. If available, tissue specimens of patients were also analyzed immunohistochemically for TS expression. The patients' median age was 65 years (range: 43-82). An overall response rate of 9.6% and a median progression-free survival (PFS) time of 3.4 months were achieved. The response rates for the second-line, third-line, fourth-line or further treatments were 9.1, 9.3 and 10.2% (p = 0.33); the median PFS were 3.3, 3.2 and 3.8 months (p = 0.21). The median follow-up duration was 14.9 months; the median overall survival (OS) was 11.9 months. The median PFS and OS were significantly longer in the TS-negative group than in the TS-positive group (5.8 months vs. 1.6 months; p = 0.03, and 14.7 months vs. 8.6 months; p = 0.04, respectively). Pemetrexed monotherapy could be considered as an option in the fourth or later lines of treatment of previously treated patients with advanced NSCLC as well as a second- or third-line treatment, and TS expression may be a potentially predictive factor for pemetrexed efficacy in NSCLC patients.
Currently, there are no standard cytotoxic treatments for non-small-cell lung cancer (NSCLC) patients beyond third-line therapy. The purpose of this study was to evaluate the efficacy of amrubicin ...monotherapy as a salvage treatment in heavily pretreated NSCLC patients.
The records of NSCLC patients who received amrubicin monotherapy as a third or later line of chemotherapy at a Kitasato University Hospital between January 2009 and December 2012 were retrospectively reviewed. Amrubicin was administered to patients by intravenous injection at a dose of 35 or 40 mg/m(2) daily on 3 consecutive days, and cycles were repeated at 3-week intervals.
There were 36 patients who met the inclusion criteria. Their median number of prior chemotherapy treatments was 4 (range 2-7), and the median number of chemotherapy cycles per patient was 4 (range 1-9). Grade 3 or 4 hematologic toxicities included neutropenia (61.1%), leukopenia (58.3%), thrombocytopenia (22.2%) and anemia (11.1%). Febrile neutropenia occurred in 8 patients (22.2%). Nonhematologic toxicities were mild. The overall response rate, median progression-free survival time and median survival time were 8.3%, 1.7 months, and 6.3 months, respectively. Progression-free survival time was the same, i.e. 1.7 months in both groups i.e. the 35- and the 40-mg/m(2)-dose groups.
Amrubicin exhibits modest activity and acceptable toxicity when used as a third or later line of chemotherapy for advanced NSCLC.
We conducted a phase I trial of erlotinib, an epidermal growth factor receptor tyrosine kinase inhibitor, combined with amrubicin, a topoisomerase II inhibitor. The aim was to determine the maximum ...tolerated dose, the dose-limiting toxicities (DLTs), and the pharmacokinetics of this combination in patients with non-small cell lung cancer who had received previous chemotherapy.
A total of 9 patients with stage IV disease were treated at 3-week intervals with erlotinib once daily on days 1 through 21 plus a 5-minute intravenous injection of amrubicin on days 1 through 3.
The dose levels evaluated were erlotinib (mg/body)/amrubicin (mg/m): 100/30 (n=3), 100/35 (n=3), and 150/30 (n=3). The maximum tolerated dose of erlotinib and amrubicin was 100 mg/body and 35 mg/m because 2 of the 3 patients experienced DLTs during the first cycle of treatment at the third dose level of 150 mg/body and 30 mg/m. Cessation of erlotinib administration for 8 days because of grade 3 leukopenia and grade 3 skin infection (erysipelas) were the DLTs. No drug-drug interactions between erlotinib and amrubicin were observed in this study. The overall response rate was 33%, including 3 partial responses, in the 9 patients. The median progression-free survival for all patients was quite long, 11.3 months, and the median overall survival has not yet been reached.
Combined erlotinib plus amrubicin therapy seems to be highly effective, with acceptable toxicity, against non-small cell lung cancer. The recommended dose for phase II studies was erlotinib 100 mg once daily on days 1 through 21, and amrubicin 35 mg/m on days 1 through 3 administered every 21 days.
Purpose
We conducted a phase I trial of irinotecan (CPT-11), a topoisomerase I inhibitor, combined with amrubicin, a topoisomerase II inhibitor, with recombinant human granulocyte colony-stimulating ...factor (rhG-CSF) support to overcome the neutropenia associated with this particular combination. The aim was to determine the maximum tolerated dose (MTD) of amrubicin combined with a fixed dose of CPT-11 and the dose-limiting toxicities (DLTs) of this combination in extensive-stage small-cell lung cancer (ED-SCLC) patients.
Methods
Fifteen patients with ED-SCLC were treated at 3-week intervals with amrubicin on days 1–3 plus 60 mg/m
2
CPT-11 on days 1 and 8. In addition, prophylactic rhG-CSF (50 μg/m
2
) was given from day 4 to day 21, except on the day of CPT-11 administration. Amrubicin was started at 30 mg/m
2
and then escalated in 5 mg/m
2
increments until MTD was reached.
Results
The MTD of amrubicin was 35 mg/m
2
, since 2 of 4 patients experienced DLTs during the first cycle of treatment at the 40 mg/m
2
dose level. Neutropenia, neutropenic fever, ileus, and diarrhea were the DLTs. There were 13 partial responses among the 13 assessable patients, yielding an overall response rate of 100 %. Median progression-free survival and overall survival were 7.4 months and 13.4 months, respectively.
Conclusion
The combination of amrubicin and CPT-11 showed high activity against ED-SCLC with acceptable toxicity. Use of rhG-CSF allowed the dose of amrubicin to be raised 40 % above that in the original regimen (60 mg/m
2
CPT-11 and 25 mg/m
2
amrubicin).

There have been few reports on the efficacy or safety of combination therapy with carboplatin-paclitaxel plus bevacizumab(TC+Bev)in previously treated patients with non-small cell lung ...carcinoma(NSCLC).
The objective of this study was to assess the efficacy and safety of TC+Bev as second-line therapy and beyond for previously treated NSCLC patients.
A total of 17 patients previously treated with NSCLC at the Kitasato University Hospital between April 2010 and February 2012 were enrolled in this retrospective study. On day 1 all patients received a 200mg/m2 dose of paclitaxel by intravenous infusion over a 3-h period, followed by infusion of carboplatin at a dose corresponding to an AUC of 6.0 min mg/mL, and then by Bev at a dose of 15mg/m2. The treatment course was repeated every three or four weeks. Patients continued to receive Bev monotherapy every 3 weeks thereafter until evidence of disease progression or unacceptable toxicity developed.
Median age: 60 years old(range 39-74 years old); gender: male/female, 6/11; PS 0-1/≥2, 17/0; clinical stage:III B/IV postoperative recurrence, 0/16/1; EGFR mutation status: positive/negative/unknown, 7/9/1; histological type: adenocarcinoma in all patients; median number of prior regimens: 3. 4(1-6); median number of cycles(induction phase): 3(1-6). The objective response rate and disease control rate were 17. 6% and 70. 6%, respectively, and the median progression-free survival time was 4. 7 months. There were no treatment-related deaths, and the toxicities of the treatment regimen were acceptable.
TC+Bev therapy exhibits activity in previously treated NSCLC patients and has acceptable toxicity. Further study is warranted to confirm our results.
Background. Bronchial granular cell tumors are rare. Furthermore only 5 cases of bronchial granular cell tumors accompanying lung cancer have been reported in Japan. Case. A 44-year-old man with ...blood-stained sputum and cough was referred to our hospital, because a cavitary lesion was pointed out in the left upper lung field on chest X-ray films in another medical clinic. Chest CT images showed a cavitary lesion 6 cm in diameter in left S^<1+2>. On bronchoscopy, the cavitary lesion in the left upper lobe was diagnosed as non-small cell lung cancer. A polypoid lesion was also unexpectedly discovered at the orifice of the right upper bronchus. Biopsy revealed a granular cell tumor, because HE stain showed oval cells containing eosinophilic granules and anti-S-100 antibody and NSE staining were positive on immunohistochemical studies. We performed left upper lobectomy by video-assisted thoracoscopic surgery for the lung cancer and we followed the granular cell tumor by observation. Conclusion. Bronchial granular cell tumor is still rare. However, numbers of incidentally-found cases with bronchoscopy are increasing recently. We believe that careful observation of whole bronchial lumen by bronchoscopy is important even if preceding diagnostic imaging, including CT scans, do not show any signs of abnormalities.
