Comparison of efficacy and safety of second- and third-generation TKIs for non-small-cell lung cancer with uncommon EGFR mutations.

Background: The efficacy of definite for non-small-cell lung cancer (NSCLC) with uncommon epidermal growth factor receptor (EGFR) mutations has been preliminarily demonstrated. However, there is a paucity of data with which to compare the efficacy and safety of second- and third-generation TKIs in patients with NSCLC carrying uncommon EGFR mutations.

Methods: We compared the efficacy and safety of second- and third-generation TKIs in all NSCLC patients in whom next-generation sequencing confirmed uncommon EGFR mutations, including G719X, S768I, and L861Q.

Comparison of the immunotherapy efficacy between invasive mucinous and non-mucinous adenocarcinoma in advanced lung cancer patients with KRAS mutation: a retrospective study.

Invasive mucinous adenocarcinoma (IMA) is a rare variant of adenocarcinoma with unique clinical, radiological, and pathological features, among which KRAS mutation is the most common. However, the differences in the efficacy of immunotherapy between KRAS-positive IMA and invasive non-mucinous adenocarcinoma (INMA) patients remain unclear. Patients with KRAS mutated adenocarcinomas receiving immunotherapy between June 2016 and December 2022 were enrolled.

Immune checkpoint inhibitors beyond first-line progression with prior immunotherapy in patients with advanced non-small cell lung cancer.

Background: Immunotherapy, monotherapy, and immunotherapy plus platinum-based chemotherapy are the standard treatments for advanced non-small cell lung cancer (NSCLC) patients with negative driver genes. However, the impact of similar continuing immunotherapy beyond progression (IBP) of first-line immunotherapy for advanced NSCLC has not yet been shown. This study aimed to estimate the impact of immunotherapy beyond first-line progression (IBF) and evaluate the factors associated with second-line efficacity.

Background: We aimed to determine the clinical. outcomes of various immune checkpoint inhibitor (ICI) combinations for the treatment of non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) mutations. The results predicted the treatment efficacy of these combinations.

Efficacy and safety of immune checkpoint inhibitors (ICIs) combined with antiangiogenic therapy for thymic epithelial tumors (TETs): a retrospective study.

Background: Immune checkpoint inhibitors (ICIs) combined with antiangiogenic therapy have shown promising antitumor activity against a range of advanced cancers. However, evidence is lacking as to whether this combination therapy could benefit thymic epithelial tumors (TETs). We aimed to explore the efficacy and safety of this combination therapy in advanced TETs.

The efficacy of immune checkpoint inhibitors (ICIs) on KRAS-mutant advanced non-small cell lung cancer (NSCLC) remains controversial. This retrospective study compared the effects of ICIs treatment and chemotherapy on the prognosis of patients with KRAS-mutant advanced NSCLC and different mutant subtypes in the real world. The study included 95 patients with KRAS-mutant advanced NSCLC.

Clinical outcomes of immune checkpoint inhibitor therapy for advanced lung adenosquamous carcinoma.

Background: Primary adenosquamous carcinoma (ASC) of the lung is a rare and aggressive disease and limited information is available on the efficacy of immune checkpoint inhibitors (ICIs) for this disease. Here, we evaluated the expression status of programmed death-1 ligand 1 (PD-L1) and efficacy of ICIs in patients with pulmonary ASC.

Methods: The efficacy and toxicity of ICIs were examined in 38 patients with previously treated lung ASC from November 2017 to October 2021 in Zhejiang Cancer Hospital (Hangzhou, China).

The efficacy of small molecule anti-angiogenic drugs in previously treated Thymic carcinoma.

Background: Antiangiogenic drugs have shown initial efficacy in the treatment of advanced thymic carcinomas (TCs); however, data are limited. In this study, we provide real-world data relating to the efficacy of antiangiogenic drugs for the treatment of patients with TCs.

Methods: We retrospectively collected data on clinical progress after first-line chemotherapy in TCs patients who were treated with small molecule antiangiogenic drugs at our institution between January 2010 and December 2021.

Comparison of Efficacy and Safety of Platinum-Based Chemotherapy as First-Line Therapy between B3 Thymoma and Thymic Carcinoma.

Background: B3 type thymoma is defined as a well-differentiated thymic carcinoma and is similar to a thymic carcinoma. However, the differences between them are not well defined. In addition, the data to compare the efficacy and safety of platinum-based chemotherapy as first-line therapy between B3 thymoma and thymic carcinoma are lacking.

Efficacy of EGFR-Tyrosine Kinase Inhibitors for advanced non-small cell lung cancer patients harboring rare EGFR mutations of exon 18 E709X.

EGFR-tyrosine kinase inhibitors (TKIs) show efficacy against lung cancer, and afatinib has been used as a standard therapy for patients with non-small cell lung cancer (NSCLC) with EGFR rare mutations such as S768I, G719X, and L861Q. However, the efficacy of EGFR-TKIs against NSCLC with EGFR rare mutations of exon 18 E709X has been less studied. The present study aimed to analyze the efficacy and safety of EGFR-TKIs in NSCLC patients with rare mutations.

The effect of EGFR-TKIs on survival in advanced non-small-cell lung cancer with EGFR mutations: A real-world study.

Background: Few large-scale studies have been published using real-world data related to overall survival (OS) improvements in advanced epidermal growth factor receptor (EGFR)-mutant lung cancer patients; therefore, little is known regarding the characteristics of patients who could benefit most from EGFR-tyrosine kinase inhibitors (TKIs). Our study aimed to assess whether EGFR-TKI treatment confers survival benefits among advanced non-small-cell lung cancer (NSCLC) patients harboring EGFR mutations in the Chinese population.

Patients And Methods: A total of 6451 advanced NSCLC patients were diagnosed between January 1, 2013 and June 30, 2019 in Zhejiang Cancer Hospital.

Baseline anemia predicts a poor prognosis in patients with non-small cell lung cancer with epidermal growth factor receptor mutations: a retrospective study.

Background: Anemia is relatively common in cancer patients, and baseline anemia is associated with poor survival in patients with non-small cell lung cancer (NSCLC). However, there is a lack of large-sample studies of patients with NSCLC with epidermal growth factor receptor (EGFR) mutations.

Methods: We retrospectively analyzed anemia‑related data for patients with NSCLC and EGFR mutations who were admitted to Zhejiang Cancer Hospital from January 2013 to June 2019 and treated with targeted therapy.

Clinical outcomes of EGFR-TKIs in advanced squamous cell lung cancer.

We aimed to explore the treatment efficacy of first-generation epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) for lung squamous cell carcinoma (SCC) patients and identify potential beneficial subgroups of EGFR-mutated lung SCC patients in this study. Between February 1st, 2013 and December 1st, 2021, 657 advanced lung SCC patients were enrolled at Zhejiang Cancer Hospital. Amplification refractory mutation system PCR or next-generation sequencing were used to detect gene abnormality.

The incidence of primary and acquired BRAF mutations is low in non-small cell lung cancer (NSCLC), with limited demographic and treatment outcome data available for this patient population. We evaluated lung cancer samples with programmed cell death ligand 1 (PD-L1) information extracted from 12 051 cases (cohort A) of lung cancer from OncoPanscan™-based sequencing of tissue (Genetron Health) and conducted retrospective multicenter data analysis using the database of Zhejiang Cancer Hospital and four other centers (cohort B, including 73 primary BRAF mutation and 14 acquired BRAF mutation cases) to compare treatment outcomes of patient groups with primary and acquired BRAF mutations. In cohort A, after propensity score analysis, 165 samples of NSCLC with BRAF mutations were screened along with 165 paired non-BRAF mutation samples.
