BACKGROUND No treatment options are available for patients with metastatic colorectal cancer that progresses after all approved standard therapies, but many patients maintain a good performance status and could be candidates for further therapy. An international phase 3 trial was done to assess the multikinase inhibitor regorafenib in these patients. (More)
Colorectal cancer is a major cause of death in Japan, where it accounts for the largest number of deaths from malignant neoplasms in women and the third largest number in men. Many new treatment methods have been developed over the last few decades. The Japanese Society for Cancer of the Colon and Rectum (JSCCR) guidelines 2010 for the treatment of(More)

BACKGROUND Angiogenesis is an important therapeutic target in colorectal carcinoma. Ramucirumab is a human IgG-1 monoclonal antibody that targets the extracellular domain of VEGF receptor 2. We assessed the efficacy and safety of ramucirumab versus placebo in combination with second-line FOLFIRI (leucovorin, fluorouracil, and irinotecan) for metastatic(More)
Paclitaxel scheduled every 3 weeks has shown a response rate of ∼20% for gastric cancer, with modest hematological toxicity. Weekly administration of paclitaxel in patients with breast or ovarian cancer has shown equivalent efficacy and milder toxicity compared with an every-3 week schedule. We investigated, retrospectively, the antitumor effects and(More)
BACKGROUND Tumour mutational status is an important determinant of the response of metastatic colorectal cancer to targeted treatments. However, the genotype of the tissue obtained at the time of diagnosis might not accurately represent tumour genotype after multiple lines of treatment. This retrospective exploratory analysis investigated the clinical(More)
BACKGROUND We investigated the tolerability of cetuximab plus radiotherapy in Japanese patients with untreated locally advanced squamous cell carcinoma of the head and neck. METHODS Patients with epidermal growth factor receptor-expressing locally advanced squamous cell carcinoma of the head and neck received cetuximab (400 mg/m(2) initial dose then 250(More)
OBJECTIVE The concordance of KRAS mutation detection between the amplification refractory mutation system-Scorpion assay and direct sequencing was evaluated with clinically available formalin-fixed, paraffin-embedded specimens of metastatic colorectal cancers. METHODS Genomic DNA from 120 macrodissected specimens was examined by the amplification(More)
BACKGROUND AND AIM Colonic perforation is the serious accidental complication. The aim of this study is to analyze the clinical presentation and management of recent iatrogenic perforations during therapeutic colonoscopy. METHODS Consecutive patients referred to four academic cancer centers in Japan were retrospectively reviewed using each center's(More)
BACKGROUND Treatments that confer survival benefit are needed in patients with heavily pretreated metastatic colorectal cancer. The aim of this trial was to investigate the efficacy and safety of TAS-102-a novel oral nucleoside antitumour agent. METHODS Between August 25, 2009, and April 12, 2010, we undertook a multicentre, double-blind, randomised,(More)
