Clinical analysis of 1629 newly diagnosed malignant lymphomas in current residents of Sichuan province, China.

Previous studies in other provinces of China (Beijing, Xinjiang, Shanxi, Jiangxi, Shanghai, Guangdong, and Taiwan) suggest that the distributions of lymphoma subtypes differ compared with Western populations. In order to evaluate the characteristics of malignant lymphoma in Sichuan, China, we analyzed case series data from incident lymphoma patients diagnosed in 2008 from three hospitals, including a total of 1629 cases and including only current residents of Sichuan. The median age of diagnosis for cases was 54 years, with a higher proportion of male cases compared with female cases.

Chemotherapy with or without gefitinib in patients with advanced non-small-cell lung cancer: a meta-analysis of 6,844 patients.

Background: Gefitinib is widely used in patients with advanced non-small-cell lung cancer (NSCLC), in whom chemotherapy had failed. Previous trials reported inconsistent findings regarding the efficacy of gefitinib on overall survival (OS) and progression free survival (PFS). This study was to evaluate the effects of chemotherapy plus gefitinib versus chemotherapy alone on survival of patients with NSCLC.

Objective: To analyze the clinicopathologic characteristics of gastroenteropancreatic neuroendocrine neoplasm(GEP-NET) and explore the prognostic factors for patients with GEP-NET.

Methods: Retrospectively reviews were conducted for the charts of 68 patients diagnosed pathologically with GEP-NET and treated at Sichuan Cancer Hospital during January 2001 to June 2012. The information of prognostic factors was retrieved and analyzed.

Cancer department nurses' attitudes and practices in response to the sexual issues of pelvic radiation patients: a survey in Sichuan, China.

Our aim was to investigate cancer department nurses' attitudes and practices in response to pelvic radiation patients' sexual issues in Sichuan, China. A self-made questionnaire survey was conducted with 150 registered nurses of six hospitals in China. Nurses were asked about their experiences regarding consultation about sexual issues and attitudes toward the sex-related statements of pelvic radiation patients.

[Effect of quercetin on heat shock protein expression in HepG2 cells determined by SILAC].

Objective: To detect the changes of heat shock protein(HSP) expression in human hepatocellular carcinoma HepG2 cells after treated by quercetin through a proteomics strategy termed SILAC (stable isotope labeling by amino acids in cell culture)-MS (mass spectrometry).
