The study present the results of the dose-setting study of concomitant weekly administration of paclitaxel and tegafur·uracil (UFT) for metastatic breast cancer. Eligible patients who entered the study underwent two or more courses of weekly paclitaxel + UFTtherapy as the protocol therapy. The initial dose (level 1) was paclitaxel, 80 mg/m 2 and UFT, 400 mg/day. At level 2, paclitaxel remained the same, but UFTwas increased to 600 mg/day. At level 3, only paclitaxel was increased to 90 mg/m 2. Twelve patients were enrolled in this study between September 2000 and September 2002. Three patients were assigned to level 1. Grade 3 liver dysfunction (increased aspartate aminotransferase and alanine aminotransferase) was noted in one patient and grade 4 neutropenia was noted in one patient, showing that dose-limiting toxicity was detected in 2/3 patients. In accordance with the protocol, UFT was fixed at 400 mg/day and paclitaxel was decreased to 60 mg/m 2 at level -1, and then increased to 70 mg/m 2 at level 0. The overall effective rate after completion of two courses was 33% (3/9) including one case of complete response and two cases of partial responses. The remaining patients presented with stable diseases and no patient had progressive disease. In this study, weekly paclitaxel with concomitant UFTwas administered. The recommended doses of paclitaxel and UFTwere determined to be 70 mg/m 2 and 400 mg/day, respectively. As the toxicity profile shows, the highest toxicity level of this regimen was neutropenia and liver dysfunction, and dose-limiting toxicity was neutropenia.

Objective: Infusional 5-fluorouracil and leucovorin with oxaliplatin is one of the standard regimens for patients with pretreated metastatic colorectal cancer, as well as for first-line chemotherapy. FOLFOX4 has shown its efficacy in pivotal trials, but patients must make twiceweekly hospital visits. FOLFOX6 is a more convenient regimen, requiring a visit once every two weeks. The objective of this study was to evaluate the efficacy and safety profile of FOLFOX6 in Japanese patients with pretreated colorectal cancer. Method: Fifty-one metastatic colorectal cancer patients who failed to respond to first-line chemotherapy were enrolled in the study from April to July 2005. Oxaliplatin, 5-fluorouracil and l-leucovorin were administered every two weeks. Oxaliplatin (100 mg/m2) and l-leucovorin (200 mg/m2) were given intravenously over 2 h followed by 5-fluorouracil bolus 400 mg/m2 i.v. and 46-h infusion of 2400 mg/m2. The primary endpoint was the response rate. Results: Two patients had no measurable lesions and were excluded from the efficacy analysis. Of the 49 eligible patients, one complete response and 6 partial responses were observed, resulting in a response rate (RR) of 14.3% (95% confidence interval: 5.9-27.2%). Median time to treatment failure and progression-free survival was 4.4 and 5.3 months, respectively. Overall survival was 11.4 months. The incidence of grade 2/3 (Debiopharm neurotoxicity criteria) peripheral neuropathy was 41.2%, whereas the overall incidence of grade 3/4 neutropenia was 43.2%. Conclusion: The results of our study suggest that FOLFOX6 had an acceptable profile in terms of both efficacy and safety in previously treated colorectal cancer patients. © The Author (2010).

Background: In a phase II, open-label, multicentre Japanese study, sunitinib demonstrated antitumour activity and acceptable tolerability in metastatic renal cell carcinoma patients. Final survival analyses and updated results are reported. Methods: Fifty-one Japanese patients with a clear-cell component of metastatic renal cell carcinoma (25 treatment-naïve; 26 cytokine-refractory) received sunitinib 50 mg orally, once daily (Schedule 4/2). Overall and progression-free survivals were estimated by the Kaplan-Meier method. Objective response rate (per Response Evaluation Criteria in Solid Tumours) and safety were assessed with an updated follow-up. Results: First-line and pretreated patients received a median 6.0 and 9.5 treatment cycles, respectively. Investigator-assessed, end-of-study objective response rate was 52.0, 53.8 and 52.9% in first-line, pretreated and overall intent-to-treat populations, respectively. The median progression-free survival was 12.2 and 10.6 months in first-line and pretreated patients, respectively. Fourteen patients per group died (56 and 54%), and the median overall survival was 33.1 and 32.5 months, respectively. The most common treatment-related Grade 3 or 4 adverse events and laboratory abnormalities were fatigue (24%), hand-foot syndrome (18%), decreased platelet count (55%), decreased neutrophil count (53%) and increased lipase (49%). No Grade 5 treatment-related adverse events occurred. Forty patients (78%) required dose reduction, and 13 (25%) discontinued, due to treatment-related adverse events. Conclusions: With the median overall survival benefit exceeding 2.5 years, and acceptable tolerability, in first-line and pretreated Japanese metastatic renal cell carcinoma patients with Eastern Cooperative Oncology Group performance status 0/1, sunitinib showed a favourable risk/benefit profile, similar to Western studies. However, there was a trend towards greater efficacy and more haematological adverse events in Japanese patients. © The Author (2010). Published by Oxford University Press. All rights reserved.

Background: We conducted a phase II trial to evaluate the efficacy and safety of preoperative chemotherapy with docetaxel (DTX) plus S-1 for resectable advanced gastric cancer. Patients and Methods: A total of 47 patients from 14 centers were centrally registered. Patients received DTX (35 mg/m2) on days 1 and 15, and daily oral administration of S-1 (80 mg/m2/day) for days 1-14 every 4 weeks for two courses, followed by gastrectomy with D2 lymphadenectomy. The primary endpoint was pathological response rate (pRR). This study was registered in the UMIN clinical trial registry (UMIN000000875). Results: The primary endpoint pRR was 47 % (90 % confidence interval (CI), 34-60 %; p < 0.0001). The response rate to preoperative chemotherapy using Response Evaluation Criteria in Solid Tumors (RECIST) was 34 %. Forty-six patients (98 %) underwent surgery, and curative resection was performed in 44 patients. Thirty-seven patients completed the protocol treatment. The most common toxicities of neoadjuvant chemotherapy were grade 3/4 neutropenia (42 %), febrile neutropenia (4 %), grade 2 anorexia (21 %), and fatigue (15 %). Treatment-related death and operative mortality was not observed in this study. Conclusions: The combination of docetaxel and S-1 was well tolerated. This is promising as a preoperative chemotherapy regimen for patients with potentially resectable advanced gastric cancer. © 2014 Society of Surgical Oncology.

Recently, bone marrow has been considered as playing a critical role in the generation of both metastasis and recurrent disease. The accumulation of a single microRNA in the bone marrow has the potential to regulate the translation of multiple genes in cancer metastasis and may therefore serve as a prognostic marker for cancer recurrence. MicroRNA micro-array analysis was performed to compare microRNA levels in bone marrow from 4 breast cancer patients with recurrent disease and 4 patients without recurrence. Accumulation of two of these microRNAs, miR-21 and miR-181a, in the recurrent breast cancer cases was validated by RT-PCR in bone marrow from 291 additional breast cancer cases. Expression of a common target gene, PDCD4, was also determined in bone marrow from 291 breast cancer cases. Increased miR-21 and miR-181a levels were significantly associated with shortened disease-free survival (DFS; p=0.0003, 0.0007) and overall survival (OS; p=0.0351, 0.0443), respectively. While low PDCD4 expression was also significantly associated with poorer DFS (p=0.036). Multivariate analysis identified bone marrow miR-21 and mR-181a levels as valuable independent prognostic factors, with correlation coefficients that were significantly higher than that of the transcript of their common target gene. Accumulation of miR-21 and miR-181a in bone marrow appears to be associated with prognosis in breast cancer patients. The much higher significant correlation with microRNA levels and prognosis suggests epistatic effects on multiple target genes in the bone marrow of breast cancer patients.
