Article Synopsis
  • A systematic review and meta-analysis examined the effects of vitamin C on digestive system cancers (DSCs) through data from 32 studies involving over 1.6 million participants.
  • Results indicated that higher dietary intake of vitamin C significantly reduced the risk of various DSCs, including oral, pharyngeal, esophageal, and gastric cancers, but its effect varied by cancer type.
  • Although plasma vitamin C level was only linked to a reduced risk of gastric cancer, further clinical studies are needed to fully understand its role in the incidence of all DSCs.

Mechanics shape cell and tissue plasticity and maintain their homeostasis. In cancers, mechanical signals regulate cancer hallmarks via mechanotransduction pathways, such as proliferation, metastasis and metabolic reprogramming. However, comprehensive characterization of mechanotransduction pathway genes and their clinical relevance across different cancer types remains untouched.

Article Synopsis
  • Perilipin-2 (PLIN2) helps form lipid droplets (LDs) in fat cells and interacts with another protein called CGI-58.
  • Scientists used special tests to find out how different mutations in PLIN2 affect its ability to connect with CGI-58 and the formation of lipid droplets.
  • The study found that changing certain parts of the PLIN2 protein can either help or hurt its ability to work with CGI-58 and may affect how fat cells produce lipids.

Background: Previous studies have demonstrated that prophylactic cranial irradiation (PCI) could reduce the risk of brain metastases and prolong the overall survival (OS) of patients with small cell lung cancer (SCLC). However, it remains controversial whether the efficacy and safety of PCI would be subjected to the different characteristics of patients with extensive stage of SCLC. This meta-analysis aims to evaluate the efficacy and safety of PCI in patients with extensive stage SCLC.

Objective: With the increasing incidence of stage IA lung cancer ≤1 cm in size, the optimal primary treatment remains to be controversial, and thus, we compared the survival of these patients treated with radiotherapy, wedge resection, segmentectomy, or lobectomy in a large population.

Methods: We identified patients with stage IA lung cancer ≤1 cm in size between 2004 and 2015 in the Surveillance, Epidemiology, and End Results (SEER) database. We compared the overall survival (OS) via Kaplan-Meier analysis and conducted Cox regression analysis via propensity score matching (PSM) method to identify the relative hazard ratio (HR) and difference of OS among these treatments in the subgroup stratified by four variables (age, total number of tumors, pathological grade, and histology).
