Background: Currently, the established approach for addressing stage IV non-small cell lung cancer (NSCLC) involves combining chemotherapy with immunotherapy. However, the necessity for molecular analysis prior to commencing immunotherapy often results in a delay in its initiation following the commencement of chemotherapy. Therefore, this study aimed to study the significance of postponing immunotherapy on pertinent patient outcomes.

Research Question: Do the single-nodal and multiple-nodal statuses stratify the prognosis of patients with non-small cell lung cancer (NSCLC)?
Study Design And Methods: Using the National Cancer Database, we analyzed patients with pathologically staged N1 and N2 NSCLC. Nodal descriptors were classified into pathological single N1 (pSingle-N1), pathological multiple N1 (pMulti-N1), pathological single N2 (pSingle-N2), and pathological multiple N2 (pMulti-N2).
Sublobar resection is a standard surgical procedure for small-sized non-small-cell lung cancer (NSCLC). However, the clinical role of adjuvant chemotherapy for small-sized NSCLC with pathological lymph node (LN) metastasis after sublobar resection is unknown. The National Cancer Database was queried for NSCLC patients between 2004 and 2018.

Purpose: Because patients younger than 40 years are rarely enrolled in clinical trials in non-small cell lung cancer (NSCLC), their survival benefit of immune checkpoint inhibitors (ICIs) needs to be clarified.
Methods: The National Cancer Database was queried for patients who were diagnosed with stage IV NSCLC between 2016 and 2018. ICIs were administered in the first-line setting.

Background: The exclusion of patients with autoimmune disease has been a topic of cancer immunotherapy trial. This study aims to find recent trends in exclusion of autoimmune disease.
Methods: Using the website clinicaltrials.
Objectives: Small cell lung cancer (SCLC) is a lethal histologic subtype of lung cancer. Although the Commission on Cancer recommends pathological examination of at least 10 lymph nodes dissected (LNDs) for resected early-stage non-small cell lung cancer, its survival benefit of LNDs in patients with early-stage SCLC is unknown.
Methods: The National Cancer Database was queried for SCLC patients with clinical stage I-II and clinical N0, NX disease per AJCC 7 edition who had undergone lobectomy between 2004 and 2017.
Objectives: Role of adjuvant radiation therapy in stage III (N2) non-small cell lung cancer has been controversial over the decades. Recent large, randomized trials have demonstrated that adjuvant radiation did not improve overall survival or disease-free survival; however, the trials either excluded or enrolled very few cases that have undergone neoadjuvant chemotherapy. Role of adjuvant radiation after neoadjuvant chemotherapy remains unclear.

Background: A randomized trial of lobectomy versus segmentectomy for small-sized (≤ 20 mm) non-small cell lung cancer (NSCLC) showed that patients who had undergone segmentectomy had a significantly longer overall survival (OS) than those who had lobectomy. More attention is needed regarding the required extent of thoracic lymphadenectomy in patients with small-sized NSCLC who undergo sublobar resection.
Methods: The National Cancer Database was queried for patients with clinically node-negative NSCLC ≤ 20 mm who had undergone sublobar resection between 2004 and 2017.
Mucoepidermoid carcinoma (MEC) represents 10-15% of salivary neoplasms. Due to their low incidence, it is challenging to conduct clinical trials and develop treatment guidelines. Although surgery is the most common approach for a resectable tumor, various treatment options such as chemotherapy, radiotherapy, and immunotherapy have been investigated.
View Article and Find Full Text PDFObjective: Although concurrent chemoradiation has been the standard of care for unresectable stage III non-small cell lung cancer (NSCLC) due to increased survival and decreased disease progression, patients with poor performance status cannot tolerate chemotherapy toxicity well. Durvalumab, an immune checkpoint inhibitor targeting the programmed death receptor-1 (PD-1) / programmed death-ligand 1 (PD-L1) axis, demonstrated efficacy as maintenance therapy after definitive chemoradiation. However, the role of immunotherapy in those who cannot tolerate chemoradiation is unclear.

Because elderly patients with NSCLC are often excluded from clinical trials as a result of lower functional capacity or comorbidities, the prognostic impact of chronological age on the efficacy of ICIs is unclear. The National Cancer Database was queried for stage IV NSCLC patients between 2014 and 2015.

The role of the presence of multiple T3 descriptors in prognosis remains unknown.
Methods: Using the National Cancer Database and the AJCC seventh edition, pathologically staged (R0) N0M0 NSCLC cases diagnosed in 2010 to 2016 were analyzed.
Importance: Administration of pembrolizumab plus concurrent chemoradiation therapy (cCRT) may provide treatment benefit to patients with locally advanced, stage III non-small cell lung cancer (NSCLC).
Objective: To evaluate treatment outcomes and safety of pembrolizumab plus cCRT in stage III NSCLC.
Design, Setting, And Participants: The phase 2, nonrandomized, 2-cohort, open-label KEYNOTE-799 study enrolled patients between November 5, 2018, and July 31, 2020, from 52 academic facilities and community-based institutions across 10 countries.
Prognosis of extensive stage small cell lung cancer (ES-SCLC) remains poor. Previous randomized trials suggested consolidation chest radiation (CXRT) has a modest survival benefit; however, its role in subgroups of ES-SCLC, especially ipsilateral pleural effusion (IPE), is unknown. Using National Cancer Database (NCDB), 283,347 ES-SCLC cases diagnosed between 2004 and 2017 were screened.

Background: Despite approvals of immune checkpoint inhibitors in both small cell and non-small cell lung cancers, the role of immunotherapy in large cell neuroendocrine carcinoma (LCNEC) in lung is undefined.
Methods: Using the National Cancer Database (NCDB), Stage IV lung LCNEC cases diagnosed from 2014 to 2016 were analyzed. Information regarding cancer treatment was limited to first course of therapy, including surgery for primary lesion, radiation, chemotherapy, and immunotherapy.
Immunocheckpoint inhibitors (ICIs) have become a standard pharmacological therapy in non-small cell lung cancer (NSCLC). Because brain metastases (BMs) have historically been listed as exclusion criteria in previous clinical trials involving ICIs in advanced NSCLC, the survival benefit from ICI in NSCLC patients with BMs remains unclear. The National Cancer Database was queried for stage IV NSCLC patients with or without BMs between 2014 and 2015.

Background: Although randomized trials demonstrated survival benefit of adjuvant chemotherapy, previous reports have suggested that its use in elderly populations for early stage non-small cell lung cancer (NSCLC) was infrequent. The current status of adjuvant chemotherapy in this population is unknown.
Methods: Using the Surveillance, Epidemiology, and End Results (SEER) database, we examined the incidence of chemotherapy in resected stage II-III NSCLC between 2004 and 2015.

Background: Most patients with pancreatic cancer have non-resectable disease at the time of diagnosis and usually die within 6-12 months. Despite indications in other solid tumors, the role of immunotherapy (IO) is unknown for late stage, advanced pancreatic cancer.
Methods: Using the National Cancer Database (NCDB), cases of Stage IV pancreatic cancers diagnosed in the period of 2014-2016 with at least 30-day follow up were retrospectively analyzed.
Recent studies have demonstrated that there are differences among races in efficacy, tolerance and other outcomes in oncologic care. Some of these differences may be explained by different pharmacogenetics; however, social and environmental factors that can affect oncology practice are relatively underestimated. In this review we will focus on differences in environment, education and research between Japan and the US when it comes to lung cancer clinical practice.

Background: The American Society of Clinical Oncology and Friends of Cancer Research submitted recommendations to the FDA to reduce barriers in clinical trial participation. They proposed the removal of several specific exclusion criteria, including brain metastasis. Clinical trials involving small cell lung cancer (SCLC) have varying exclusion criteria regarding brain metastasis.
