Gedetailleerde beschrijving
This is a phase 2/3 randomized clinical trial evaluating two dose escalation strategies during prostate stereotactic body radiotherapy (SBRT). A total of 186 patients with prostate adenocarcinoma will be enrolled and randomized in a 1:1 ratio to one of two treatment arms.
In both arms, patients will receive 3625 cGy delivered to the planning target volume (PTV) over 5 fractions. In Arm A, patients will receive a boost to the prostate gland. In Arm B, patients will receive a boost to the dominant intra-prostatic lesion (DIL) identified on pre-treatment magnetic resonance imaging (MRI).
The primary objective is to evaluate chronic genitourinary (GU) and gastrointestinal (GI) toxicities grade 2 or higher from 6 months to 2 years post-treatment using the Common Terminology Criteria for Adverse Events (CTCAE). Secondary objectives include evaluation of acute and chronic GU and GI toxicities using CTCAE, Radiation Therapy Oncology Group (RTOG), and Expanded Prostate Cancer Index Composite (EPIC) domains, as well as biochemical progression-free survival at 5 years.
Participants will be followed for up to 5 years after completion of treatment.

Deelnemersgroep / Arm |
Interventie / Behandeling |
|---|---|
|
Actieve vergelijker: Arm A: boost to prostate alone
Participants assigned to Arm A will receive external beam radiation therapy consisting of 3625 cGy to the planning target volume (PTV), plus a boost of 4000 cGy to the clinical target volume (CTV), consisting of the prostate alone without a margin.
Treatment will be delivered over 5 fractions with at least 36 hours between fractions via simultaneous integrated boost (SIB).
|
External beam radiation therapy delivered via linear accelerator-based SBRT using simultaneous integrated boost
|
|
Experimenteel: Arm B: boost to dominant intra-prostatic lesion (DIL)
Participants assigned to Arm B will receive external beam radiation therapy consisting of 3625 cGy to the planning target volume (PTV), plus a boost of 4500 cGy to the dominant intra-prostatic lesion (DIL).
Treatment will be delivered over 5 fractions with at least 36 hours between fractions via simultaneous integrated boost (SIB).
