Study on Prostate Salvage Using High-dose-rate Brachytherapy (PROSCATE)
Multicenter Prospective Observational Study on Prostate Salvage Using High-dose-rate Brachytherapy
A prospective, observational, multicenter study analyzing salvage treatment for prostate cancer-diagnosed via next-generation imaging (choline positron emission tomography (PET)/prostate-specific membrane antigen (PSMA) PET and magnetic resonance imaging (MRI)) and positive biopsy-using two fractions of high-dose-rate (HDR) brachytherapy.

The objectives of this prospective, multicenter study are:
-
Primary:
1. Biochemical relapse-free survival, defined as the time to biochemical relapse (nadir plus 2 ng/mL - Phoenix criteria).
-
Secondary:
- Local relapse-free survival, defined as the time from treatment to local relapse confirmed by imaging (choline PET/MRI).
- Analysis of acute and chronic toxicity (Common Terminology Criteria for Adverse Events [CTCAE] version 5).
- Assessment of patient quality of life before and after treatment to analyze the impact of local re-irradiation on daily life using the following questionnaires: International Prostate Symptom Score (IPSS), Functional Assessment of Cancer Therapy-Prostate (FACT-P), and European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire - Prostate Module (EORTC QLQ-PR25).
Primary outcome measure: Biochemical relapse-free survival, and analysis of toxicity and quality of life in patients treated with salvage brachytherapy following radical treatment.
Study population, total number of subjects, and duration: Patients who received radical-intent radiotherapy as their initial treatment (brachytherapy alone, external beam radiotherapy, or external beam radiotherapy plus a brachytherapy boost) and were diagnosed with local recurrence via next-generation imaging techniques (choline PET/PSMA PET) and prior biopsy; these patients are scheduled to undergo salvage brachytherapy as part of routine clinical practice. A calculated sample size of 63 patients will be reached over a 2-year recruitment period. Follow-up will be conducted according to standard clinical practice every 6 months for the 4-year duration of the study.

Biochemical relapse-free survival
Zeitfenster: From the date of salvage brachytherapy to 48 months after treatment
|
Time from salvage brachytherapy to biochemical recurrence of prostate cancer, defined according to the Phoenix definition as a rise in prostate-specific antigen (PSA) of ≥2 ng/mL above the post-treatment PSA nadir. Patients without biochemical recurrence will be censored at the date of their last available PSA assessment or at the end of the study follow-up. PSA measurements will be obtained at 1 month after treatment and subsequently every 6 months through 48 months. |

Incidence of Late and Chronic Treatment-Related Toxicity
Zeitfenster: From 1 month after salvage brachytherapy to 48 months after treatment
|
Incidence and severity of late and chronic treatment-related toxicity following salvage brachytherapy, assessed according to the Common Terminology Criteria for Adverse Events (CTCAE), version 5.0. Toxicities will include genitourinary and gastrointestinal toxicities and other treatment-related adverse events identified during follow-up. |
From 1 month after salvage brachytherapy to 48 months after treatment
|
|
Local Relapse-Free Survival
Zeitfenster: From the date of salvage brachytherapy to 48 months after treatment
|
Time from salvage brachytherapy to radiologically confirmed local recurrence of prostate cancer. Local recurrence will be assessed using imaging techniques, including prostate MRI, choline PET, and/or PSMA PET, according to routine clinical practice. Patients without radiologically confirmed local recurrence will be censored at the date of their last available imaging assessment or at the end of the study follow-up. |
From the date of salvage brachytherapy to 48 months after treatment

|
Incidence of Acute Treatment-Related Toxicity
Zeitfenster: From the date of salvage brachytherapy to 1 month after treatment
|
Incidence and severity of acute treatment-related toxicity following salvage brachytherapy, assessed according to the Common Terminology Criteria for Adverse Events (CTCAE), version 5.0. Acute toxicity will include genitourinary and gastrointestinal toxicities and other treatment-related adverse events occurring during the acute post-treatment period. |
From the date of salvage brachytherapy to 1 month after treatment
|
|
Change in International Prostate Symptom Score (IPSS) From Baseline
Zeitfenster: Baseline and every 6 months after salvage brachytherapy through 48 months
|
Change in urinary symptoms assessed using the International Prostate Symptom Score (IPSS). The IPSS will be assessed before salvage brachytherapy and during follow-up every 6 months. The change from baseline will be evaluated over the study follow-up period. |
Baseline and every 6 months after salvage brachytherapy through 48 months
|
|
Change in Prostate Cancer-Specific Quality of Life (FACT-P) From Baseline
Zeitfenster: Baseline and every 6 months after salvage brachytherapy through 48 months
|
Change in health-related quality of life assessed using the Functional Assessment of Cancer Therapy-Prostate (FACT-P) questionnaire. The FACT-P is a 39-item questionnaire assessing health-related quality of life in patients with prostate cancer. The total score ranges from 0 to 156, with higher scores indicating better health-related quality of life. The questionnaire will be administered before salvage brachytherapy and during follow-up every 6 months. Changes from baseline in the FACT-P total score will be evaluated throughout the study follow-up period. |
Baseline and every 6 months after salvage brachytherapy through 48 months

|
Change in Prostate Cancer-Specific Quality of Life (EORTC QLQ-PR25) From Baseline
Zeitfenster: Baseline and every 6 months after salvage brachytherapy through 48 months
|
Change in prostate cancer-specific health-related quality of life assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire - Prostate Module (EORTC QLQ-PR25). The EORTC QLQ-PR25 consists of 25 items scored on a 0 to 100 scale after linear transformation. Higher scores indicate greater symptom burden for symptom scales and higher levels of functioning or activity for the sexual activity/function scales. The questionnaire will be administered before salvage brachytherapy and during follow-up every 6 months. Changes from baseline in the EORTC QLQ-PR25 scores will be evaluated throughout the study follow-up period.. |
