Different approach to M descriptor for future staging of oligometastatic disease in SCLC: A cross-sectional survival analysis.

Purpose: This study aimed to investigate the impact of oligometastasis and the M descriptor on survival in small cell lung cancer (SCLC).

Methods: This multicenter, retrospective study included patients with newly diagnosed extensive-stage SCLC(ES-SCLC) from 2010 to 2020. Subgroups: Group 1: single metastasis in a single organ, Group 2: 2-5 metastases in a single organ, Group 3: 6 or more metastases in a single organ, and Group 4: metastases in two or more organs.

The Utility of C-Reactive Protein, Procalcitonin, and Leukocyte Values in Predicting the Prognosis of Patients with Pneumosepsis and Septic Shock.

The predictive value of changes in C-reactive protein (CRP), procalcitonin, and leukocyte levels, which are commonly used in the diagnosis of infection in sepsis and septic shock, remains a topic of debate. The aim of this study was to evaluate the effectiveness of changes in CRP, procalcitonin, and leukocyte counts on the prognosis of 230 patients admitted to the intensive care unit (ICU) with the diagnosis of sepsis and pneumonia-related septic shock between 1 April 2022 and 31 December 2023, and to investigate whether any of these markers have a superior predictive value over the others in forecasting prognosis. This single-center, retrospective, cross-sectional observational study included patients who developed sepsis and septic shock due to community-acquired pneumonia and were admitted to the ICU.

Potential role of pre-treatment bone marrow SUVmean to liver SUVmean ratio (BM/L) and comparison of primary tumour FDG uptake with brain FDG uptake in predicting survival in limited-stage lung cancers.

Introduction: The survival rates of patients with limited-stage small-cell lung cancer are low despite curative treatment. Accordingly, we investigated the disease prognosis by comparing the pre-treatment bone marrow mean standardised uptake values (SUVmean) / liver SUVmean ratio (BM/L) and primary tumour FDG uptake and brain FDG uptake to prognosis.

Materials And Methods: This was an observational, retrospective, single-centre study of patients with limited-stage small-cell lung cancer.

Characteristics of our hypoxemic COVID-19 pneumonia patients receiving corticosteroids and mortality-associated factors.

Background: COVID-19 is a disease associated with diffuse lung injury that has no proven effective treatment yet. It is thought that glucocorticoids may reduce inflammation-mediated lung injury, disease progression, and mortality. We aimed to evaluate our patient's characteristics and treatment outcomes who received corticosteroids for COVID-19 pneumonia.

Clinical management of lung cancer patients with respiratory symptoms during the COVID-19 pandemic.

Objective: There are many clinical conditions, such as lung cancer, that need to be followed up and treated during a pandemic. Providing health care for patients who are immune-suppressive requires extra care.

Method: Among 108 lung cancer patients who had been hospitalized during the COVID-19 pandemic, 18 with respiratory symptoms were evaluated retrospectively.

The success of non-invasive mechanical ventilation in lung cancer patients with respiratory failure.

Introduction And Aim: Despite the improvement in survival among patients with lung cancer as a result of the development of novel treatment options, acute respiratory failure (ARF), which may occur because of the disease itself, comorbidities or complications in treatment may be life threatening. The most commonly utilised treatment option in cancer patients with ARF is invasive mechanical ventilation (IMV). The prognosis of lung cancer patients admitted to the intensive care unit is poor.

Small cell lung cancer stem cells display mesenchymal properties and exploit immune checkpoint pathways in activated cytotoxic T lymphocytes.

Small cell lung cancer (SCLC) is an aggressive tumor type with early dissemination and distant metastasis capacity. Even though optimal chemotherapy responses are observed initially in many patients, therapy resistance is almost inevitable. Accordingly, SCLC has been regarded as an archetype for cancer stem cell (CSC) dynamics.

Effect of Asbestos Exposure on the Frequency of EGFR Mutations and ALK/ROS1 Rearrangements in Patients With Lung Adenocarcinoma: A Multicentric Study.

Objective: The aim of this study is to investigate the effect of asbestos exposure on cancer-driver mutations.

Methods: Between January 2014 and September 2018, epidermal growth factor receptor (EGFR), anaplastic lymphoma receptor tyrosine kinase (ALK), and c-ros oncogene 1 receptor tyrosine kinase gene (ROS1) alterations, demographic characteristics, asbestos exposure, and asbestos-related radiological findings of 1904 patients with lung adenocarcinoma were recorded.

Results: The frequencies of EGFR mutations, ALK, and ROS1 rearrangements were 14.

The Clinical Impact of Re-biopsies in Lung Adenocarcinoma: a Retrospective Multicenter Study.

If a patient's cancer progresses while undergoing targeted therapy, a re-biopsy is not mandatory. But when evaluating the benefits and risks on a case-by-case basis (transformation to small cell, assessing for a clinical trial), physicians should inform patients about the possible need for a re-biopsy (5). This was a retrospective and multicentre study.

Treatment outcomes in oligometastatic non-small-cell lung cancer: A single-centre experience.

Background: Even in oligometastatic stage 4 disease, survival rates are higher when curative approaches focus on both the primary tumour and metastasis. So, we aim to analyse our results of oligometastatic disease retrospectively.

Methods: In total, data on 52 non-small-cell lung cancer (NSCLC) patients with limited metastasis (one to three synchronous/metachronous) were retrospectively analysed.

Prognostic significance of preoperative consolidation to maximum tumour diameter ratio and SUVmax in pathological stage I lung adenocarcinoma.

Objectives: Consolidation/tumour (C/T) ratio means the maximum diameter of the consolidation is divided by the maximum diameter of the tumour and it is predictive for pathologic subtypes and prognosis after resection of the tumour. The purpose of this study is to clarify impact of C/T ratio along with maximum standardized uptake value (SUV) in pathological stage I lung adenocarcinoma.

Methods: Only patients with pathological stage I lung adenocarcinoma diagnosed by resection were included.

Complications of silicone Y stents placed due to malignant airway stenosis.

Introduction: Malignant central airway obstruction around the main carina often requires placement of Y‑shaped stents. In this study, we aimed to determine the safety of silicone Y stents placed around the main carina in the malignant airway obstruction by examining the long term complications, emergence times and treatment approaches of complications.

Materials And Methods: Between May 2012 and July 2015, 47 silicone Y stents were placed in 46 patients with malignant external compression or mixed type stenosis around the main carina.

Comparison of two new techniques for the management of malignant central airway obstruction: argon plasma coagulation with mechanical tumor resection versus cryorecanalization.

Background: The development of central airway obstruction during malignant diseases is an important cause of morbidity and mortality. Endobronchial therapies can decrease the patient's symptoms and improve quality of life. Here, we compare airway recanalization methods: argon plasma coagulation with mechanical tumor resection (APC + MTR) and cryorecanalization (CR efficiency, complications, restenosis rate, and time to restenosis) in patients with malignant exophytic endobronchial airway obstruction.

How many samples would be optimal for endobronchial cryobiopsy?

Background: Cryobiopsy, which provides larger specimens without crush artifact, is a good option for the diagnosis of visible endobronchial tumors. While there are several papers on diagnostic performance, application protocols vary between centers. In this study, we aimed to find the optimal number of cryobiopsies in endobronchial tumors.
