Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a retrospective monoinstitutional study which analyses the results of advanced radiotherapy (IGRT, IMRT, SBRT, and PET-guided) performed for radical, adjuvant, or salvage purposes in patients with low, intermediate, high, and very high-risk prostate cancer, or with biochemical, lymph node, or oligometastatic recurrence treated between 2004 and 2024.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a single-center, retrospective study (PROST-ART) that has as its primary objective the evaluation of the efficacy of radiotherapy treatments performed in patients with early-stage, advanced, metastatic prostate disease, with biochemical relapses after surgery, with local relapses after radiotherapy, or oligometastatic/oligoprogressive disease. The aim of the study is to measure the biochemical relapse-free survival (bRFS), local and regional relapse (LR, regional relapse, RR), distant metastases-free survival (DMS), clinical relapse (DFS), disease-free survival (PCSS), and overall survival (OS) from both disease diagnosis and the end of radiotherapy until the last useful follow-up, or until the patient's death. In addition, the acute and late toxicity of treatments will be assessed from the start of treatment until the last follow-up/death of the patient and the period without other oncological treatments, from the end of treatment until the start of another oncological treatment/last follow-up.

At least 200 patients treated in the last 5 years, some receiving stereotactic radiotherapy to the prostate, or prostate and seminal vesicles, and the others pelvic lymph node and prostate irradiation, who are still alive and contactable, and agree to participate, will be included in a survey on quality of life (QoL). These patients, after signing an informed consent for the collection of new information, will receive an EORTC QLQ-PR25 quality of life questionnaire, in order to quantify the impact of toxicity. In addition, the radiomic characteristics of the computed tomography/ PET-CT performed for treatment planning along with evaluation of the results will be extracted to identify related predictive factors.

The QoL study is configured as retrospective as the questionnaire will only be an expression, from the patient's point of view, of the toxicity of the previous treatment.
