Background: Combining bevacizumab with platinum-based chemotherapy significantly improves survival for patients with advanced non-squamous non-small cell lung cancer. The objective of this study was to assess the proportion of patients who could receive this combined therapy.
Methods: This was a retrospective single centre analysis of patients treated between 2007 and 2008. Exclusion criteria for bevacizumab included: squamous cell carcinoma, contraindication to platinum-based chemotherapy, uncontrolled hypertension, haemoptysis superior to 2.5 mL, recent surgery, and/or tomodensitometric criteria after independent review by two radiologists (contact with a proximal vessel, tracheobronchial involvement, cavitation). Cardiovascular diseases and central tumour location were not systematically considered as contraindications.
Results: Among 194 patients analysed, 21 (10.8%) to 35 (18%) patients were eligible for bevacizumab, whether or not cardiovascular diseases and central tumour location were considered as contraindications. The kappa coefficient was 0.49.
Conclusion: Even though the proportion of patients who can receive chemotherapy plus bevacizumab may vary according to the eligibility criteria chosen and the interpretation of the CT scan, it is unlikely to exceed 25% of patients in daily practice.

Multiple endocrine neoplasia type 1 (MEN1) syndrome is an autosomal dominant disorder caused by a germline pathogenic variant in the MEN1 tumor suppressor gene. Patients with MEN1 have a high risk for primary hyperparathyroidism (PHPT) with a penetrance of nearly 100%, pituitary adenomas (PitAd) in 40% of patients, and neuroendocrine neoplasms (NEN) of the pancreas (40% of patients), duodenum, lung, and thymus. Increased MEN1-related mortality is mainly related to duodenal-pancreatic and thymic NEN.

This study focuses on the design, synthesis, and evaluation of benzimidazole derivatives for their anti-tumor activity against A549 and PC-3 cells. Initial screening using the MTT assay identified compound 5m as the most potent inhibitor of A549 cells with an IC of 7.19 μM, which was superior to the positive agents 5-Fluorouracil and Gefitinib.

Background: Pre-cancer onset of cachexia raises uncertainties regarding the optimal timing for early intervention in lung cancer patients. We aimed to examine changes in physical function, nutritional status, and cachexia incidence in patients with lung cancer from the initial visit to treatment initiation and determine the effect of these changes on lung cancer treatment.
Methods: This single-center retrospective cohort study enrolled patients suspected of having advanced lung cancer who visited Kansai Medical University Hospital between January and February 2023 and were definitely diagnosed with the disease.
Circulating Tumor DNA Detection for Recurrence Monitoring of Stage I Non-Small Cell Lung Cancer Treated With Microwave Ablation.

Purpose: As microwave ablation continues to be used in patients with inoperable stage I non-small cell lung cancer (NSCLC), it is particularly important to monitor efficacy. Whether plasma ctDNA detection can predict its efficacy should be illustrated.
Methods: We recruited 43 patients with inoperative stage I NSCLC, all of whom underwent biopsy-synchronous microwave ablation (MWA).

Long-term use of low-dose aspirin has been demonstrated to reduce cancer risk, but the duration of necessary medication use remains uncertain. This study aimed to investigate the long-term chemoprotective effect of aspirin among the Chinese population. This population-based study included all aspirin users between 2000 and 2019.
