BACKGROUND D2 gastrectomy is recommended in US and European guidelines, and is preferred in east Asia, for patients with resectable gastric cancer. Adjuvant chemotherapy improves patient outcomes after surgery, but the benefits after a D2 resection have not been extensively investigated in large-scale trials. We investigated the effect on disease-free(More)
PURPOSE The oral mammalian target of rapamycin inhibitor everolimus demonstrated promising efficacy in a phase II study of pretreated advanced gastric cancer. This international, double-blind, phase III study compared everolimus efficacy and safety with that of best supportive care (BSC) in previously treated advanced gastric cancer. PATIENTS AND METHODS(More)
BACKGROUND Platelets have been reported to act as transporters of tumor-originated vascular endothelial growth factor (VEGF), contributing to tumor angiogenesis and progression. Serum VEGF per platelet count, as an indirect theoretical estimate of VEGF in platelets, may predict the malignant potential of tumors. However, its prognostic significance is still(More)
Genome-wide association studies of lung cancer reported in populations of European background have identified three regions on chromosomes 5p15.33, 6p21.33, and 15q25 that have achieved genome-wide significance with p-values of 10(-7) or lower. These studies have been performed primarily in cigarette smokers, raising the possibility that the observed(More)
To identify common genetic variants that contribute to lung cancer susceptibility, we conducted a multistage genome-wide association study of lung cancer in Asian women who never smoked. We scanned 5,510 never-smoking female lung cancer cases and 4,544 controls drawn from 14 studies from mainland China, South Korea, Japan, Singapore, Taiwan and Hong Kong.(More)
BACKGROUND Gefitinib was compared with pemetrexed as second-line therapy in a clinically selected population previously treated with platinum-based chemotherapy. METHODS A phase 3 trial of gefitinib (250 mg/day) versus pemetrexed (500 mg/m(2) on day 1, every 3 weeks) was conducted in patients who had never smoked and who had advanced pulmonary(More)
The tumor suppressor gene, TP53, is located on chromosome 17p13.1 and is critical for DNA repair, cell-cycle control, and apoptosis. TP53 also plays a crucial function in the tumorigenesis of lung cancer. Inactivation of TP53 via genetic alterations such as missense mutations is often associated with lung cancer. In this study, potential association of TP53(More)
BACKGROUND The balance in the immune system between immune surveillance against non-self-antigens and tolerance of self-antigens is known to be associated with the prognosis of breast cancer patients. However, immunologic signals in tumor microenvironment according to biological characteristics of cancer cells have not been clearly elucidated. CD4(+) T(More)
Lung cancer is one of the deadliest and commonly diagnosed neoplasms. Early diagnosis of this disease is critical for improving clinical outcome and prognosis. Because the early stages of lung cancer often produce no symptoms, it is necessary to identify biomarkers for early detection, prognostic evaluation, and recurrence monitoring of the cancer. To(More)
Genome-wide association studies (GWAS) have mapped risk alleles for at least 10 distinct cancers to a small region of 63 000 bp on chromosome 5p15.33. This region harbors the TERT and CLPTM1L genes; the former encodes the catalytic subunit of telomerase reverse transcriptase and the latter may play a role in apoptosis. To investigate further the genetic(More)
