Brain metastases represent a major clinical challenge in the management of non-small-cell lung cancer, particularly in patients with epidermal growth factor receptor mutations, constituting a leading cause of morbidity and mortality. In recent years, significant advancements have been made in both local therapies and systemic treatments. Nevertheless, managing central nervous system disease remains complex, encompassing challenges such as optimal therapy sequencing, resistance mechanisms, oligoprogression, the role of the blood–brain barrier, diagnostic strategies, and the influence of the brain tumor microenvironment. Despite advances, brain metastases in non-small-cell lung cancer remain an unmet need. Local treatments like radiotherapy are effective but carry risks of long-term neurological side effects, while the number and burden of brain metastases remain key prognostic factors. Surgical resection may be considered even in patients with multiple brain metastases to improve clinical status, enable further therapy, and enhance survival and quality of life. With the extension of survival afforded by systemic therapies, optimizing the balance between treatment efficacy and quality of life has become critical. Integrating patient perspectives is essential in navigating these complex clinical decisions.

Background: Lung carcinoids—typical and atypical—are rare neuroendocrine tumors (NETs) representing 1–2% of lung cancers. Despite clinicopathological differences, their clinical management often mirrors lung cancer protocols rather than NET-specific recommendations. Objectives: Portray a 12-year real-world experience with lung carcinoids at a Comprehensive Cancer Center, identifying gaps in diagnostic work-up, treatment decision-making, and follow-up. Methods: Retrospective observational cohort study of adult patients with histologically confirmed lung carcinoids diagnosed at IPO Porto between January 2013 and December 2024. Demographic, clinical, imaging, and treatment data were collected from electronic patient records. Analyses were descriptive. Results: Among 179 identified cases, 129 met eligibility criteria. Median age was 62 years (range 18–84); 53.6% were women and 53.5% were non-smokers; 84.5% had ECOG-PS 0–1. The most frequent presentation was respiratory symptoms (34.1%), followed by incidental findings (43.4%, of which ~20% were during staging or surveillance of other cancers). Typical carcinoids accounted for 49.6% and atypical for 43.4%. FDG-PET/CT was requested in 70.9% of cases, including many with typical carcinoid, and SSTR-PET/CT in 64.6% (dual PET in 38.8%). Most patients (65.1%) presented with stage I disease; 17.1% were stage IV. Mean time-to-first treatment was 83 days (range 1–259). Surgery was the first treatment option for 78.3% of patients. Conclusions: This real-world series highlights heterogeneity in diagnostic pathways, excessive FDG-PET use in typical carcinoids, and non-standardized follow-up. Dedicated multidisciplinary lung-NET boards and national reference centers are needed to homogenize and streamline patient management.

Most patients with non-small-cell lung cancer (NSCLC) present with advanced/metastatic disease at diagnosis, and molecular profiling is critical in guiding treatment decisions. This retrospective cohort study aimed to characterize EGFR mutations (EGFRm) in advanced/metastatic NSCLC patients, treatment patterns, and real-world outcomes. Adults diagnosed between 2018 and 2021 and treated at a Comprehensive Care Center were included. Time-to-event outcomes were analyzed using the Kaplan–Meier method. A total of 110 patients were included, with a median age of 69.0 years (range, 37–93), 76.4% female, and 83.2% non-smokers. About 97.3% had adenocarcinomas, with 93.6% at stage IV, 40.9% with ≥ three metastatic sites (brain metastases in 24.5%), 33.6% ECOG 2–4, and 58.2% with an EGFR exon-19 deletion. A minority started supportive care or curative-intent treatment, and 81.8% underwent first-line palliative systemic therapy (TKIs, 91.1%; chemotherapy, 8.9%). Median real-world overall survival (rwOS) was 18.9 months (95% CI, 13.8–28.1). Worse rwOS was observed in patients with ECOG 2–4 versus ECOG 0–1 (10.3 vs. 22.8 months; HR 1.82, 95% CI 1.17–2.85; p = 0.008) and in patients with exon-21 L858R versus exon 19 deletions (15.8 vs. 24.2 months; HR 1.59, 95% CI 1.00–2.54; p = 0.048). In patients treated with palliative systemic treatment, median progression-free survival was 10.9 months (95% CI, 8.8–13.6). This study provides important insights regarding real-world characteristics, treatment patterns, and outcomes from a cohort of EGFRm advanced/metastatic NSCLC patients.

Lung carcinoids are rare tumors representing 1–2% of all invasive lung malignancies. They include typical and atypical carcinoids, whose distinction is made based on the mitotic index and presence or absence of necrosis. The 10-year overall survival for stage IV typical carcinoid is 47% and 18% for atypical carcinoid, reflecting the indolent growth of these tumors. There are limited approved treatment options for them and most of the evidence comes from retrospective analyses, single-arm trials, subgroup analysis of phase II/III trials for metastatic neuroendocrine tumors and extrapolation of data from phase III trials for gastroenteropancreatic neuroendocrine tumors. Management of metastatic lung carcinoids requires a multidisciplinary standardized approach in specialized centers. Treatment should have a dual objective, control of tumor growth and control of symptoms related to hypersecretion syndromes, aiming to improve quality of life and survival. In the continuum of treatment disease, locoregional treatment options need to be considered in parallel with systemic treatments. In this paper, we review the present treatment options and their rational and we give an insight into future alternatives.

Background Rearrangements in the anaplastic lymphoma kinase (ALK) gene define a molecular subgroup of non-small-cell lung carcinoma (NSCLC) that should be treated with ALK-targeting tyrosine kinase inhibitors (TKIs). Objective This study aimed to portray the Portuguese reality about the diagnosis and treatment of stage IV ALK-positive NSCLC. Methods Institutions that treat lung cancer in Portugal were invited to participate in an anonymous electronic questionnaire. A total of 22/35 geographically dispersed institutions responded. A descriptive statistical analysis of the results was performed. Results Reflex molecular testing was done in 54.6% of the institutions. Next-generation sequencing (NGS) was the preferred diagnostic method (90.9%). Typically, physicians obtained molecular study results within 14–21 days. Alectinib was the most commonly used first-line treatment. For patients with brain metastases, 86.4% of the physicians preferred alectinib and 13.6% preferred first-line brigatinib. In the case of asymptomatic oligoprogression in the central nervous system, 85.7% of physicians performed local treatment and kept the patient on a TKI; if symptomatic, 66.7% gave local treatment and stayed with the TKI, while 28.6% gave local treatment and altered the TKI. For patients with symptomatic systemic progression, 47.6% and 38.1% of physicians prescribed lorlatinib after initial treatment with alectinib or brigatinib, respectively. After progression on lorlatinib, 42.9% of respondents chose chemotherapy and 57.1% requested detection of resistance mutations. Conclusions NGS is widely used for the molecular characterization of ALK-positive NSCLC in Portugal. The country has access to up-to-date therapy. Overall, national clinical practice follows international recommendations for the diagnosis and treatment of ALK-positive NSCLC.

In the non-small-cell lung cancer (NSCLC) subtype, adenocarcinoma is the most common histology. The choice of first-line treatment depends on the mutational status. We present a case of a 54-year-old non-smoker woman with lung adenocarcinoma and extensive metastatic disease at diagnosis. The genetic analysis demonstrated a sensitizing epidermal growth factor receptor (EGFR) exon 19 mutation and she began treatment with a first-generation EGFR tyrosine kinase inhibitor (TKI), erlotinib. Due to successively acquired resistances and disease progression, six treatment lines were pursued, including third-generation EGFR TKI and chemotherapy. The patient accomplished an overall survival of 47 months. This case emphasized the importance of monitoring tumor mutational alterations, allowing us to implement a multi-line treatment. Targeted therapy in advanced NSCLC largely improved the overall survival of these patients.
