Few studies have examined the relationship of lifestyle factors with mortality among patients with colorectal cancer. ⋯ Healthier lifestyle before cancer diagnosis was associated with improved overall survival after diagnosis with colorectal cancer.

Randomized Controlled Trial
A randomized phase 2 trial of erlotinib versus pemetrexed as second-line therapy in the treatment of patients with advanced EGFR wild-type and EGFR FISH-positive lung adenocarcinoma.
The current study was undertaken to investigate the efficacy and safety of erlotinib versus pemetrexed as second-line therapy for patients with advanced epidermal growth factor receptor (EGFR) wild-type and EGFR fluorescence in situ hybridization (FISH)-positive lung adenocarcinoma. ⋯ There were no significant differences noted with regard to efficacy between erlotinib and pemetrexed in the second-line setting for patients with advanced EGFR wild-type and EGFR FISH-positive lung adenocarcinoma. Both regimens appear to be effective treatment options for these patients.

Well-differentiated thyroid cancer (WDTC) is a prevalent disease, which is increasing in incidence faster than any other cancer. Substantial direct medical care costs are related to the diagnosis and treatment of newly diagnosed patients as well as the ongoing surveillance of patients who have a long life expectancy. Prior analyses of the aggregate health care costs attributable to WDTC in the United States have not been reported. ⋯ Health care costs of WDTC are substantial. Unlike other cancers, the majority of the cost is incurred in the initial and continuing phases of care. With the projected increasing incidence, population, and survival trends, costs will continue to escalate.

The American Cancer Society (ACS), the Centers for Disease Control and Prevention (CDC), the National Cancer Institute (NCI), and the North American Association of Central Cancer Registries (NAACCR) collaborate annually to provide updates on cancer incidence and death rates and trends in these outcomes for the United States. This year's report includes the prevalence of comorbidity at the time of first cancer diagnosis among patients with lung, colorectal, breast, or prostate cancer and survival among cancer patients based on comorbidity level. ⋯ Cancer death rates in the United States continue to decline. Estimates of survival that include the probability of dying of cancer and other causes stratified by comorbidity level, age, and stage can provide important information to facilitate treatment decisions.

The utility of circulating Epstein-Barr Virus (EBV) DNA as a tumor marker for nasopharyngeal carcinoma (NPC) detection suggests that it might improve the diagnostic performance of anti-EBV antibody markers in NPC screening. In this study, the authors evaluated whether circulating EBV DNA load is capable of distinguishing NPC patients from high-risk individuals who have positive anti-EBV antibodies. ⋯ The plasma EBV DNA load may improve the accuracy of diagnosing NPC in high-risk individuals, but it appears to have limited value in screening patients who have early stage NPC and predicting NPC development.
