Hypofractionated Post-prostatectomy Radiotherapy (HYPORT)for Localized Prostate Cancer

Not Applicable

Recruiting

• Conditions: Localized Prostate Cancer
• Interventions: Radiation: Conventional radiation therapy; Radiation: Hypofractionated radiation therapy

• Registration Number: NCT06325995
• Lead Sponsor: Changhai Hospital

Brief Summary

The aim of this trial is to compare the safety outcomes of Hypofractionated postprostatectomy radiotherapy (HYPORT) and Conventionally fractionated postprostatectomy radiotherapy(COPORT) in treating patients with localized prostate cancer.

Accumulating evidence has proven the safety and feasibility of HYPORT for localized prostate cancer.But for localized prostate cancer,the optimal dose per fraction of HYPORT is still on its way.

It is not yet known whether giving HYPORT(57.5-65 Gy in 23-26 daily fractions of 2.5 Gy ) with or COPORT may work better in treating patients with prostate cancer.

Detailed Description

The present study will be conducted as a prospective, open-label, two arms clinical trial.

Patients with pathologically confirmed prostate cancer and completed radical resection of prostate cancer, will be randomized in a 1:1 ratio between arm A (COPORT) and arm B (HYPORT).

The patients in arm A will receive COPORT(66-74 Gy in 33-37 daily fractions of 2 Gy ). The patients in arm B will receive HYPORT(57.5-65 Gy in 23-26 daily fractions of 2.5 Gy ). After completion of study treatment, patients were followed up once a month for the first 3 months and once every 3 months after 3 months for a total of 5 years.

The primary endpoints of the study are toxicities parameters.The secondary endpoints include ,progression-free survival (PFS),medical economics,quality of life (QoL), overall survival (OS)and prostate cancer-specific survival period. The progression-free survival (PFS) including biochemical progression-free survival (bPFS), and radiological progression-free survival.

Arm && Interventions

Group	Intervention	Description
A (COPORT)	Conventional radiation therapy	COPORT over 7 weeks.
B（HYPORT）	Hypofractionated radiation therapy	HYPORT over 5 weeks.

Primary Outcome Measures

Name	Time	Method
Incidence of radiotherapy-related gastrointestinal and urogenital tract adverse events	Assessment toxicities parameters at 5 years	Common Terminology Criteria for Adverse Events (CTCAE) 5.0

Secondary Outcome Measures

Name	Time	Method
medical expenses	Assessment the medical economics during the treatment,up to 7 weeks	The medical expenses during the time of interventions.The medical expenses include the payments of doctor and hospital visits, co-pays, radiotherapy and so on.
Overall survival (OS)	Assessment overall survival (OS) at 5 years	To assess the overall survival (OS)
Prostate cancer-specific survival	Assessment prostate cancer-specific survival at 5 years	To assess the prostate cancer-specific survival
Physical Activity Rank Scale-3 (ARS-3)	through study completion, an average of 5 years	To assess the physical activity rank.The scale was compiled by Japanese psychologist KIMIO HASHIMOTO and introduced and revised by Liang Deqing from Wuhan Physical Education University. There are only 3 items in this scale, which adopts 5 grades from 1 to 5, and examines the level of physical activity from 3 aspects: intensity, time and frequency of participating in physical activity.
5-year progression-free survival (PFS)	Assessment progression-free survival (PFS) at 5 years	To assess progression-free survival (PFS) including biochemical progression-free survival (bPFS), and radiological progression-free survival.
quality of life (QoL)	through study completion, an average of 5 years	Expanded Prostate Cancer Index (EPIC-26)：The EPIC is a prostate cancer health-related quality of life (HRQOL) self-administered instrument measuring patient-reported urinary, bowel, sexual, and hormonal symptoms related to prostate cancer treatments. Response options for each item form a Likert scale with scores transformed linearly to a 0-100 scale. Domain scores are also on a 0-100 scale with higher scores representing better HRQOL.
