Artificial Intelligence Driven Personalisation of Radiotherapy and Concomitant Androgen Deprivation Therapy for Prostate Cancer Patients (the HypoPro Trial)

Официальное название

Prostate-only, Dose-escalated Radiotherapy Plus Concomitant Androgen Deprivation Therapy in Primary Localized, NCCN High Risk and MMAI Classifier Low or Intermediate-risk Prostate Cancer - a Prospective, Single-arm, Phase II Study

Обзор

The aim of this prospective, single-arm phase II study is the individualization of both radiotherapy (RT) and androgen deprivation therapy (ADT) duration for patients with high-risk localized prostate cancer (PCa) according to the National Comprehensive Cancer Network (NCCN) based on multimodal artificial intelligence (MMAI) classification. All patients will receive (i) a dose escalation to the prostate via HDR brachytherapy (boost), (ii) twelve months of ADT and (iii) extremely hypofractionated RT to the prostate (5 fractions). This way, patients in the HypoPro trial will receive a prostate-only dose escalation and benefit from shortening of the ADT compared with current guideline recommendations.

Подробное описание

In Cyprus approximately 800 men are newly diagnosed with PCa every year. Prostate cancer caused 6.1 million disability-adjusted life-years (DALYs) globally in 2016. The socio-economic burden is high since PCa-related life-time costs are approximately 40,000 per patient with early stage disease at initial diagnosis.

This is a prospective, single-center phase II trial. Patient participants will receive treatment for prostate +-seminal vesicles base high-dose-rate brachytherapy (HDR BT) with 15 Gray units (Gy) with minimal dose covering 90% of the prostate (D90) / 1 fraction followed by stereotactic body radiation therapy (SBRT) with 25 Gy in 5 Gy / fraction (daily); of the prostate +- seminal vesicles. Concomittant/adjuvant admission of 12 months ADT.

First: 1 fraction HDR BT including fiducial placement Second: 14 ±2 days gap Third: 5 fractions of SBRT within 5 consecutive weekdays For the HypoPro patients, we expect no significant differences in disease-free survival (DFS) rates compared to the FLAME trial (2) which one arm treated the patients with moderately-hypofractionated RT to the prostate plus dose escalation to the intraprostatic tumor plus 18-24 months of ADT. Secondary endpoints like metastatic free survival, prostate cancer survival and overall survival will depict the oncologic efficacy in this patient cohort. Thus, the results of this study might be used as the basis for a randomized-controlled trial comparing this dose escalated radiotherapy plus shortened ADT duration with the standard of care (no dose escalated RT, ADT for 2-3 years) in this highly selected treatment group: NCCN high-risk, prostate-specific membrane antigen (PSMA) positron emission tomography (PET) cN0/cM0 and MMAI low/intermediate-risk. Considering the epidemiological importance of the PCa, these results could have a significant socio-economic impact. In parallel a translational research program will address the identification of novel biomarkers to predict the treatment outcome.
