Background: With the complexity of cancer treatment rising, the role of multidisciplinary conferences (MDCs) in making diagnostic and treatment decisions has become critical. This study evaluated the impact of a thoracic MDC (T-MDC) on lung cancer care quality and survival.
Methods: Lung cancer cases over 7 years were identified from the Roswell Park cancer registry system. The survival rates and treatment plans of 300 patients presented at the MDC were compared with 300 matched patients. The National Comprehensive Cancer Network (NCCN) guidelines were used to define the standard of care. The compliance of care plans with NCCN guidelines was summarized using counts and percentages, with comparisons made using the Fisher exact test. Survival outcomes were summarized using Kaplan-Meier methods.
Results: There was improvement in median overall survival (36.9 vs 19.3 months; P < .001) and cancer-specific survival (48 vs 28.1 months; P < .001) for lung cancer patients discussed at the T-MDC compared with controls. These differences were statistically significant in patients with stages III/IV disease but not in patients with stages I/II disease. The NCCN guidelines compliance rate of treatment plans improved from 80% to 94% (P < .001) after MDC discussion. MDC recommendations resulted in treatment plan changes in 123 of 300 patients (41%).
Conclusions: Our results suggest that lung cancer patients have a survival benefit from MDC discussion compared with controls. Patients with advanced disease (stages III and IV) benefited the most. Further research is necessary to understand the precise mechanisms that drive these results.

Background: A lung cancer diagnosis has a huge impact on the psychological well-being of both patients and family caregivers. However, the current psychological stress status among dyads remains unclear. We aimed to determine the prevalence of anxiety and depression and identify the factors that influence patients with lung cancer and their caregivers.

Introduction: The systemic immune-inflammation index (SII) has emerged as a promising prognostic marker in various malignancies. However, its prognostic significance in patients with small-cell lung cancer (SCLC) treated with immune checkpoint inhibitors (ICIs) remains unclear. In this study, we evaluated the prognostic impact of the SII in patients with SCLC after ICI use.

Background And Aims: Primary lung tumors (PLTs) in children are rare, and surgery remains the key to ensure remission. Here we describe the PLTs clinical characteristics, their management, and the pulmonary outcome following surgery.
Methods: We carried out a French national cohort of pediatric PLTs from 2013 to 2023 from the FRACTURE rare pediatric tumors national database.

Immune-checkpoint inhibitors (ICIs) have transformed the treatment paradigm for advanced-stage squamous non-small-cell lung cancer (LUSC), a histological subtype associated with inferior outcomes compared with lung adenocarcinoma. However, only a subset of patients derive durable clinical benefit. In the first-line setting, multiple ICI regimens are available, including anti-PD-(L)1 antibodies as monotherapy, in combination with chemotherapy, or with an anti-CTLA4 antibody with or without chemotherapy.

KRAS-specific inhibitors have shown promising antitumor effects, especially in non-small cell lung cancer, but limited efficacy in colorectal cancer (CRC) patients. Recent studies have shown that EGFR-mediated adaptive feedback mediates primary resistance to KRAS inhibitors, but the other resistance mechanisms have not been identified. In this study, we investigated intrinsic resistance mechanisms to KRAS inhibitors using patient-derived CRC cells (CRC-PDCs).
