Long-term outcome of chemoimmunotherapy for extensive-stage small-cell lung cancer according to key clinical trial eligibility: 3-year outcomes from a prospective cohort study.

Background: Chemoimmunotherapy is the standard first-line treatment for extensive-stage small-cell lung cancer (ES-SCLC); however, its real-world long-term outcomes associated with patient backgrounds are still unclear. We explored this association using an updated large real-world prospective cohort with a minimum follow-up of 3 years.

Methods: This prospective cohort study, conducted across 32 hospitals, enrolled patients with ES-SCLC receiving carboplatin, etoposide, and atezolizumab between September 1, 2019 and September 30, 2020.

Invasive mucinous adenocarcinoma harbored exon 14 skipping mutation: case report.

Background: Lung mucinous adenocarcinoma has various genetic alterations, but there are no reported cases with exon 14 skipping mutations. Multiplex genetic testing is commonly assessed in non-small cell lung cancer (NSCLC) and treatment usually comprises molecular targeted drugs. However, the efficacy of molecular targeted drugs in lung mucinous adenocarcinoma is not reported.

Comprehensive serum biomarker analysis reveals IL-8 changes as the only predictor of the effectiveness of immune checkpoint inhibitors for patients with advanced non-small cell lung cancer.

Objectives: Programmed cell death ligand 1 (PD-L1) expression is widely used to predict the effectiveness of PD-(L)1 inhibitors despite its imperfection. Previous studies suggested the utilization of various serum biomarkers; nonetheless, findings are inconclusive because of limited sample sizes or the focus on a single biomarker in many of these studies. This study analyzed multiplex serum biomarkers to explore their predictive ability in a large cohort of patients with advanced non-small-cell lung cancer (NSCLC) treated with a PD-L1 inhibitor in a real-world setting.

Plain language summary: tarlatamab for patients with previously treated small cell lung cancer.

What Is This Summary About?: This is a summary of a phase 2 clinical study called DeLLphi-301. The study looked at how effective and safe a medicine called tarlatamab was in participants with small cell lung cancer (SCLC). Participants previously received at least two other treatments for their SCLC.

Uncovering the role of tumor cGAS expression in predicting response to PD-1/L1 inhibitors in non-small cell lung cancer.

Objectives: The impact of cGAS/STING tumor expression on PD-1/L1 inhibitor efficacy and the tumor microenvironment remain to be elucidated.

Methods: In a post-hoc analysis of a prospective biomarker study with 106 advanced NSCLC patients treated with PD-1/L1 inhibitors from December 2015 to September 2018, tumor tissue before treatment from 68 patients was analyzed. cGAS and STING expression were measured using immunohistochemical staining and H-scores.

Unsuccessful rechallenge with nivolumab in a patient with advanced non-small cell lung cancer who had a 6-year complete response and treatment-free period: Case report.

Several predictive factors of immune checkpoint inhibitor response have been reported, but there has not been sufficient exploration of which patients benefit from immune checkpoint inhibitor rechallenge. We report the case of a patient with non-small cell lung cancer who had 6 years of complete response with initial nivolumab treatment. After relapse, however, rechallenge with nivolumab did not result in tumour shrinkage or long-term response.

Can FDG-PET after neoadjuvant chemotherapy plus nivolumab predict residual disease in non-small cell lung cancer?

Neoadjuvant therapy with nivolumab improves event-free survival (EFS) in patients with resectable non-small cell lung cancer, and a pathological complete response is a predictor of longer EFS. We assessed metabolic responses using 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET) before and after neoadjuvant treatment to explore its surrogacy for pathological complete response (pCR). We describe three patients with squamous cell lung carcinoma who underwent neoadjuvant therapy with nivolumab plus chemotherapy, followed by surgery.

Neoadjuvant nivolumab plus chemotherapy followed by resection for superior sulcus tumour with high PD-L1 expression: A case report.

The standard treatment for resectable non-small cell lung cancer (NSCLC) located in the superior sulcus is neoadjuvant chemoradiotherapy followed by highly invasive resection. Based on the results of the CheckMate 816 trial, which showed a marked improvement in the efficacy of neoadjuvant chemo-immunotherapy, we report a case of minimally invasive resection after neoadjuvant nivolumab plus chemotherapy for superior sulcus NSCLC, resulting in a pathologic complete response. The patient was a 76-year-old man with a 65-mm right superior sulcus tumour diagnosed as squamous cell carcinoma with 95% PD-L1.

PRMT5 is an actionable therapeutic target in CDK4/6 inhibitor-resistant ER+/RB-deficient breast cancer.

CDK4/6 inhibitors (CDK4/6i) have improved survival of patients with estrogen receptor-positive (ER+) breast cancer. However, patients treated with CDK4/6i eventually develop drug resistance and progress. RB1 loss-of-function alterations confer resistance to CDK4/6i, but the optimal therapy for these patients is unclear.

Mannitol versus furosemide in patients with thoracic malignancies who received cisplatin-based chemotherapy using short hydration: A randomized phase II trial.

Background: Mannitol is exclusively recommended in the National Comprehensive Cancer Network guidelines for diuresis in cisplatin (CDDP)-based chemotherapy. The utility of furosemide, a widely used and convenient diuretic, thus requires clarification.

Methods: This is a prospective, single-centered, open-label, noninferiority phase II study.

Machine learning analysis of pathological images to predict 1-year progression-free survival of immunotherapy in patients with small-cell lung cancer.

Background: In small-cell lung cancer (SCLC), the tumor immune microenvironment (TIME) could be a promising biomarker for immunotherapy, but objectively evaluating TIME remains challenging. Hence, we aimed to develop a predictive biomarker of immunotherapy efficacy through a machine learning analysis of the TIME.

Methods: We conducted a biomarker analysis in a prospective study of patients with extensive-stage SCLC who received chemoimmunotherapy as the first-line treatment.

Adjacent angle size correlates with diagnostic sensitivity of endobronchial ultrasonography with a guide sheath.

Background: An association exists among the diagnostic yield of transbronchial biopsy using endobronchial ultrasonography with a guide sheath (EBUS-GS-TBB) and several factors, such as simple within or adjacent endobronchial ultrasonography (EBUS) findings. Here, we aimed to investigate whether more detailed EBUS findings affect the diagnostic yield of lung cancer in EBUS-GS-TBB.

Methods: We conducted this retrospective single-center cohort study, enrolling consecutive patients with lung cancer who underwent EBUS-GS-TBB.

A Phase II Study of High-Flow Nasal Cannula for Relieving Dyspnea in Advanced Cancer Patients.

Context: The efficacy and tolerability of high-flow nasal cannula (HFNC) for relieving dyspnea in advanced cancer patients with limited prognosis requires elucidation.

Objectives: The primary aim of this trial was to assess the efficacy and tolerability of HFNC regarding dyspnea including severe as well as moderate for longer durations in patients under palliative care.

Methods: In this prospective study, hospitalized patients with advanced cancer who had dyspnea at rest (numeric rating scale, NRS≥3) and hypoxemia were enrolled.

Perioperative Durvalumab for Resectable Non-Small-Cell Lung Cancer.

Background: Neoadjuvant or adjuvant immunotherapy can improve outcomes in patients with resectable non-small-cell lung cancer (NSCLC). Perioperative regimens may combine benefits of both to improve long-term outcomes.

Methods: We randomly assigned patients with resectable NSCLC (stage II to IIIB [N2 node stage] according to the eighth edition of the ) to receive platinum-based chemotherapy plus durvalumab or placebo administered intravenously every 3 weeks for 4 cycles before surgery, followed by adjuvant durvalumab or placebo intravenously every 4 weeks for 12 cycles.

Randomized, open-label phase II study of brigatinib and carboplatin plus pemetrexed and brigatinib alone for chemotherapy-naive patients with ALK-rearranged non-squamous non-small cell lung cancer: treatment rationale and protocol design of the B-DASH study (WJOG 14720 L).

Background: The ALTA-1L study compared brigatinib with crizotinib in untreated ALK-rearranged non-small cell lung cancer (NSCLC) patients, demonstrating the efficacy of brigatinib. Although the median progression-free survival (PFS) of brigatinib group was 24.0 months, the one-year PFS rate was 70%.
