The correlation between serum contents of TGF- β1 and IL-6 and acute radiation pneumonitis in patients with lung cancer

Conclusions In the process of radiotherapy, the increase of the serum contents of TGF-β1 and IL-6 in patients with lung cancer is closely related to the occurrence of acute RP.

Authors: Liao Y, Wang X, Zhong P, Yin G, Fan X, Huang C Abstract As a malignant tumor with poor prognosis, accurate and effective treatment of non-small cell lung cancer (NSCLC) is crucial. To predict overall survival in patients with stage II and III NSCLC, a nomogram was constructed using data from the Surveillance, Epidemiology and End Results database. Eligible patients with NSCLC with available clinical information diagnosed between January 1, 2010 and November 31, 2015 were selected from the database, and the data were randomly divided into a training set and a validation set. Univariate and multivariate Cox ...

118 patients with stage IIB-IV non-small cell lung cancer were treated with isotoxically-escalated concurrent chemoradiotherapy, to median prescribed doses of 64.5 and 67.6 Gy in 30 fractions over 5 (N=36) or 6 weeks (N=82). Toxicity was acceptable for both schedules. Overall survival was longer in 6-week than 5-week patients (median 41.2 versus 22.1 months; HR=0.56, 95%CI: 0.32-0.98, p=0.04). Progression-free survival was also longer in 6-week patients (median 21.1 versus 8.0 months; HR=0.53, 95%CI: 0.33-0.86, p=0.01).

Objective: Anti-PD-1 antibodies can cause drug-induced pneumonitis. We aimed to identify the clinical and radiologic characteristics, the incidence, risk factors, and appropriate management of pneumonitis related to anti-PD-1 immunotherapy in patients with non-small cell lung cancer (NSCLC).Materials and Methods: Medical records and chest computed tomography scans of patients with NSCLC treated with anti-PD-1 antibodies between January 2016 and June 2018 at the Kanagawa Cancer Center were retrospectively analyzed. Clinical characteristics of patients treated with anti-PD-1 antibodies who developed pneumonitis were compared...

Conclusion: For elderly NSCLC with stage IV disease, radical local treatment might significantly benefit survival in certain subgroups. Further well-designed studies are highly warranted to confirm these findings.

This article summarizes advancements in using FDG-PET for patients with locally advanced NSCLC treated with definitive radiation therapy (RT). This article discusses prognostication of outcome based on pretreatment or midtreatment PET metrics, using textural image features to predict treatment outcomes, and using PET to define RT target volumes and inform RT dose modifications. The role of PET is evolving and is moving toward using quantitative image information, with the overarching goal of individualizing therapy to improve outcomes for patients with NSCLC.

Purpose: To investigate whether a deep learning-assisted contour (DLAC) could provide greater accuracy, inter-observer consistency, and efficiency compared with a manual contour (MC) of the clinical target volume (CTV) for non-small cell lung cancer (NSCLC) receiving postoperative radiotherapy (PORT).Materials and Methods: A deep dilated residual network was used to achieve the effective automatic contour of the CTV. Eleven junior physicians contoured CTVs on 19 patients by using both MC and DLAC methods independently. Compared with the ground truth, the accuracy of the contour was evaluated by using the Dice coefficient a...
