Clinical Trial Summary

HYPO-RT-PC boost is is an open-label, multicentre, phase II trial evaluating safety and efficacy of real-time image-guided tumor-directed ultra-hypofractionated radiation boost and lymph node irradiation for patients with node-negative high risk localized prostate cancer.

Description:

HYPO-RT-PC boost is is an open-label, multicentre, phase II trial evaluating safety and efficacy of real-time image-guided tumor-directed ultra-hypofractionated radiation boost and lymph node irradiation for patients with node-negative high risk localized prostate cancer. 76 participants will be enrolled in the study.

Specific aims of the study are:

• To study the feasibility of ultra-hypofractionation target lesion boost for node-negative very high-risk prostate cancer together with lymph node irradiation (primary outcome).

• To study the effectiveness of ultra-hypofractionated target lesion boost for high-risk prostate cancer.

• To study the feasibility of defining focal boost during concomitant androgen deprivation therapy with advanced functional imaging methods.

Secondary	Overall survival failure-free survival, cancer-specific survival, and overall survival		enrollment date - 5 years
Secondary	Distant metastasis-free survival failure-free survival, cancer-specific survival, and overall survival		enrollment date - 5 years
Secondary	Time to systemic therapy failure-free survival, cancer-specific survival, and overall survival		enrollment date - 5 years
Secondary	Adverse Events according to CTCAE v5.0		start of treatment - 5 years
Secondary	Health-related quality of life assessed by the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C-30 (EORTC QLQ-C-30)	All of the scales and single-item measures range in score from 0 to 100. A high scale score represents a higher response level. Thus a high score for a functional scale represents a high / healthy level of functioning, a high score for the global health status / QoL represents a high QoL, but a high score for a symptom scale / item represents a high level of symptomatology / problems	inclusion date - 5 years
Secondary	Health-related quality of life assessed by the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire PR-25 (EORTC QLQ-PR25)	It includes subscales assessing urinary symptoms, bowel symptom), treatment-related symptom) and sexual functioning with score from 0 to 4 per item. A high scale score represents a higher response level.	inclusion date - 5 years
