Category: Thoracic Oncology Introduction: Bronchogenic tumors, predominantly non-small cell type (NSCLC), are a global health concern, with adenocarcinomas, their most common subtype, being most often diagnosed at advanced stages, making it essential to develop effective therapeutic strategies, especially for patients with NSCLC who do not express the PD-L1 (Programmed Death-Ligand 1) protein. Two pivotal studies, Keynote-189() and Keynote-407,() presented their combined results in 2023, after a 5-year follow-up,() concluding that the combination of Pembrolizumab and chemotherapy demonstrated substantial improvements in […]

Category: Thoracic Surgery Introduction: Currently, surgical resection is considered the best treatment available for early-stage lung cancer. In recent decades, minimally invasive procedures have revolutionized thoracic surgery, expanding the benefited patient population by reducing morbidity and mortality rates, incidence of complications, length of hospital stay and postoperative pain.() However, lung resections remain associated with significant morbidity and mortality, with national studies indicating a complication rate of 21.8% and an in-hospital mortality rate of 1.8% for video- assisted surgeries.() Concomitantly, various […]

Highlights PD-L1 expression by immunohistochemistry is positive in more than half on stage III non-small lung cancer. PD-L1 expression by immunohistochemistry had no relationship with clinical characteristics. PD-L1 expression by immunohistochemistry is not related to progression-free or overall survival in patients treated with chemoradiotherapy with or without surgery. ABSTRACT Objective: Currently programmed cell death protein 1 (PD-1) inhibitors in combination with other therapies are being evaluated to determine their efficacy in cancer treatment. However, the effect of PD-ligand (L) 1 […]

ABSTRACT Introduction Pulmonary neuroendocrine tumors account for approximately 20% of all primary lung tumors. Few studies summarize the current body of pulmonary neuroendocrine tumors studies worldwide. Objective A quantitative scientometric analysis was conducted to evaluate the development of applications and innovations and to analyze their contribution to various areas of improvement in treatment and diagnosis of pulmonary neuroendocrine tumors. Methods We searched for studies published in the last 20 years in the databases United States National Library of Medicine (PubMed), […]

ABSTRACT Objective To describe an experience in the preoperative localization of small pulmonary nodules and ground-glass lesions to guide minimally invasive thoracic surgery; in addition, a literature review was conducted, including the main advantages and disadvantages of the different agents used, and site marking in a hybrid operating room. Methods A retrospective search was conducted in a Interventional Radiology Department database, between March 2015 and May 2019, to identify patients undergoing preoperative percutaneous marking of lung injuries measuring up to […]

O presente artigo faz uma abordagem de questões atuais sobre os polimorfismos genéticos, que têm sido objeto de estudo translacional no contexto do carcinoma de pulmão de células não pequenas. Além disso, discute os novos potenciais biomarcadores de risco e prognóstico.
