[Molecular pathology of lung adenocarcinomas, EGFR T790M resistance mutation study].

Aim: In our institute, we have been testing EGFR T790M resistance mutations since 2019, which is the most common resistance mutation that develops during first-line, second- line EGFR TKI treatment of EGFR mutant lung adenocarcinomas. The importance of this study is that the identification of this mutation will allow the use of an effective third-generation TKI. In this article, we report on studies from January 2022 to August 2024, compared with our results from the 2019-2021 period.

TG4010 immunotherapy and first-line chemotherapy for advanced non-small-cell lung cancer (TIME): results from the phase 2b part of a randomised, double-blind, placebo-controlled, phase 2b/3 trial.

Background: MUC1 is a tumour-associated antigen expressed by many solid tumours, including non-small-cell lung cancer. TG4010 is a modified vaccinia Ankara expressing MUC1 and interleukin 2. In a previous study, TG4010 combined with chemotherapy showed activity in non-small-cell lung cancer and the baseline value of CD16, CD56, CD69 triple-positive activated lymphocytes (TrPAL) was shown to be potentially predictive of TG4010 efficacy.

Optimal line of hepatotomy for left lateral living donor liver transplantation according to the anatomical variations of left hepatic duct system.

Multiple duct anastomoses during LLS transplantation increase the incidence of biliary complications. The optimal plane of hepatotomy that results in the least number of bile ducts at the surface was investigated according to LHD variations. Ducts of 30 human livers were injected with resin and LHD branching on 3D-CT reconstructions were analyzed.

Sunitinib plus erlotinib versus placebo plus erlotinib in patients with previously treated advanced non-small-cell lung cancer: a phase III trial.

Purpose: Sunitinib plus erlotinib may enhance antitumor activity compared with either agent alone in non-small-cell lung cancer (NSCLC), based on the importance of the signaling pathways involved in tumor growth, angiogenesis, and metastasis. This phase III trial investigated overall survival (OS) for sunitinib plus erlotinib versus placebo plus erlotinib in patients with refractory NSCLC.

Patients And Methods: Patients previously treated with one to two chemotherapy regimens (including one platinum-based regimen) for recurrent NSCLC, and for whom erlotinib was indicated, were randomly assigned (1:1) to sunitinib 37.

Therapeutic vaccination with TG4010 and first-line chemotherapy in advanced non-small-cell lung cancer: a controlled phase 2B trial.

Background: Chemotherapy is the standard of care for advanced stages of non-small-cell lung cancer (NSCLC). TG4010 is a targeted immunotherapy based on a poxvirus (modified vaccinia virus Ankara) that codes for MUC1 tumour-associated antigen and interleukin 2. This study assessed TG4010 in combination with first-line chemotherapy in advanced NSCLC.

Phase III study of oral compared with intravenous topotecan as second-line therapy in small-cell lung cancer.

Purpose: Single-agent intravenous (IV) topotecan is an effective treatment for small-cell lung cancer (SCLC) after failure of first-line chemotherapy. This open-label, randomized, phase III study compared oral and IV topotecan in patients with SCLC sensitive to initial chemotherapy.

Patients And Methods: Patients with limited- or extensive-disease SCLC, documented complete or partial response to first-line therapy, Eastern Cooperative Oncology Group performance status < or = 2, and measurable recurrent disease (WHO criteria) with a treatment-free interval of > or = 90 days were assigned to treatment with either oral topotecan 2.

Open-label, multicenter, randomized, phase III study comparing oral topotecan/cisplatin versus etoposide/cisplatin as treatment for chemotherapy-naive patients with extensive-disease small-cell lung cancer.

Purpose: This open-label, randomized, multicenter phase III study compared oral topotecan/intravenous cisplatin (TC) with intravenous (IV) etoposide/cisplatin (PE) in patients with untreated extensive-disease small-cell lung cancer (ED-SCLC).

Patients And Methods: A total of 784 patients were randomly assigned to either oral topotecan 1.7 mg/m2/d x 5 with IV cisplatin 60 mg/m2 on day 5 (n = 389) or IV etoposide 100 mg/m2/d x 3 with IV cisplatin 80 mg/m2 on day 1 (n = 395) every 21 days.

Lung cancer in smoking patients inversely alters the activity of hOGG1 and hNTH1.

N-Glycosylases excise the damaged adducts from DNA. 7,8-Dihydro-8-oxoguanine in human cells is repaired by OGG1 and hNTH1. The activities of hOGG1 and hNTH1 were measured, using modified and 32P labelled oligonucleotides, in bronchial biopsy samples of smoking patients with non-small cell lung carcinoma.
