Safety and quality of life of PSMA-PET- and MRI-based focal dose escalated radiotherapy for intermediate- and high-risk prostate cancer: Primary endpoint analysis of the bi-centric phase II HypoFocal trial (ARO2020-01)
Background and Purpose
To present the primary endpoint results, toxicities and quality of life (QoL) after two-year follow-up (FU) of the HypoFocal Phase II trial.
Material and Methods
Intermediate- and high-risk prostate cancer (PCa) patients were treated with moderately hypofractionated radiotherapy (MHRT) of 60 Gy in 20 fractions and a focal-boost of up to 75 Gy in Arm A, or high-dose-rate-brachytherapy (HDR-BT) of 15 Gy to the whole-gland with a boost of up to 19 Gy, followed by external beam RT (EBRT) of 44 Gy in 20 fractions in Arm B. Boost was based on combined information by multiparametric-magentic-resonance-tomography (mpMRI) and positron-emission-tomography targeting prostate-specific-membrane-antigen (PSMA-PET). Genitourinary (GU) and gastrointestinal (GI) toxicities were assessed according to CTCAEv5.0. QoL was assessed with validated questionnaires (IPSS, QLQ-PR25 and QLQ-PR30).
Results
Twenty-five patients were treated with MHRT and 30 patients with HDR-BT + EBRT. At two-year-FU, the rate of grade 2 + GU and GI toxicity was 24 % and 8 % in Arm A and 10 % and 0 % in Arm B, respectively. Two grade 3 GI toxicities were reported in Arm A, which can be attributed to multifactorial genesis and interventions. QoL was good with significant and minimally-important-differences only in bowel symptoms in Arm A and sexual functioning in Arm B. One patient in each arm relapsed. Limitations are the relatively small sample size.
Conclusion
This is the first trial do demonstrate safety and feasibility of focal dose-escalation based on mpMRI and PSMA-PET in MHRT and HDR-BT + EBRT in intermediate- and high-risk PCa. Particularly, HDR-BT offers good toxicity and QoL profiles. Radiation proctitis demands careful management.
期刊介绍:
Radiotherapy and Oncology publishes papers describing original research as well as review articles. It covers areas of interest relating to radiation oncology. This includes: clinical radiotherapy, combined modality treatment, translational studies, epidemiological outcomes, imaging, dosimetry, and radiation therapy planning, experimental work in radiobiology, chemobiology, hyperthermia and tumour biology, as well as data science in radiation oncology and physics aspects relevant to oncology.Papers on more general aspects of interest to the radiation oncologist including chemotherapy, surgery and immunology are also published.
