Article Synopsis
  • - The study investigates the relationship between metabolic syndrome (MetS) and the incidence of various cancers, highlighting that MetS may not only be a risk factor for cardiovascular diseases but also potentially triggers certain cancers.
  • - Analyzed data from 2.7 million Japanese subjects (2005-2020) revealed that those with MetS showed a higher incidence of multiple cancers, including lung, stomach, and prostate cancers, with significant hazard ratios.
  • - The findings suggest that even early stages of MetS increase cancer risk, indicating the necessity for further research into preventative strategies targeting MetS to reduce cancer incidence.

Neoadjuvant therapy with nivolumab improves event-free survival (EFS) in patients with resectable non-small cell lung cancer, and a pathological complete response is a predictor of longer EFS. We assessed metabolic responses using 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET) before and after neoadjuvant treatment to explore its surrogacy for pathological complete response (pCR). We describe three patients with squamous cell lung carcinoma who underwent neoadjuvant therapy with nivolumab plus chemotherapy, followed by surgery.

Article Synopsis
  • - A study analyzed the effectiveness of two drugs, enzalutamide and apalutamide, in treating patients with non-metastatic castration-resistant prostate cancer (nmCRPC) to understand their efficacy and adverse event (AE) profiles.
  • - The research involved 191 patients, revealing that both drugs led to similar oncological outcomes, with comparable PSA response rates and no significant differences in progression-free survival (PFS) or overall survival (OS).
  • - However, the side effects varied, with enzalutamide causing more fatigue and apalutamide leading to more skin rashes, indicating their differential usage may depend on AE profiles despite similar efficacy.

The standard treatment for resectable non-small cell lung cancer (NSCLC) located in the superior sulcus is neoadjuvant chemoradiotherapy followed by highly invasive resection. Based on the results of the CheckMate 816 trial, which showed a marked improvement in the efficacy of neoadjuvant chemo-immunotherapy, we report a case of minimally invasive resection after neoadjuvant nivolumab plus chemotherapy for superior sulcus NSCLC, resulting in a pathologic complete response. The patient was a 76-year-old man with a 65-mm right superior sulcus tumour diagnosed as squamous cell carcinoma with 95% PD-L1.
