Dose-effect relationship in external beam radiotherapy combined with brachytherapy for cervical cancer: A systematic review.

Purpose: External beam radiotherapy with concurrent chemotherapy combined with brachytherapy has been described as the first treatment choice for locally advanced cervical cancer. This study aimed to systematically review the dose-effect relationship (DER) of target volumes and organs at risk (OARs) in external beam radiotherapy combined with brachytherapy for cervical cancer.

Material And Methods: Studies reporting DER in radical radiotherapy for cervical cancer were determined by searching PubMed, Web of Science, and Cochrane Library databases till Jan 20, 2023.

Dose-effect relationship of stereotactic body radiotherapy in non-small cell lung cancer patients.

Objective: To establish the dose effect relationship between the dose parameters of stereotactic body radiation therapy (SBRT) for early non-small cell lung cancer (NSCLC) and the local tumor control rate.

Materials And Methods: A comprehensive literature search was conducted using PubMed, the Web of Science and the Cochrane databases to determine the articles treated with SBRT in early-stage NSCLC. Original studies with complete prescription dose information, tumor local control rate and other important parameters were screened and reported.

Four-Dimensional Image-Guided Adaptive Brachytherapy for Cervical Cancer: A Systematic Review and Meta-Regression Analysis.

Purpose: The ICRU/GEC-ESTRO released the ICRU Report No. 89, which introduced the concept of four-dimensional brachytherapy and ushered in a new era of brachytherapy for cervical cancer. The purpose of this study was to evaluate the local control and late toxicity of four-dimensional brachytherapy in cervical cancer through a systematic review and to reveal the dose-response relationship between the volumetric dose paraments and the local control rate a probit model.

Nomogram predicting overall survival of rectal squamous cell carcinomas patients based on the SEER database: A population-based STROBE cohort study.

We aimed to evaluate the prognostic value of clinical and pathologic factors in rectal squamous cell carcinomas (SCC) and to construct a nomogram for their outcome prediction.The study cohort was selected from Surveillance, Epidemiology, and End Results (SEER) program between January 2004 and December 2013. Univariate and multivariate analyses were performed using Cox proportional hazards regression model to evaluate the prognostic value of involved variables.
