Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A randomized phase III trial to study the effect of adding lymph node irradiation in patients with poor prostate-specific antigen (PSA) response during salvage radiotherapy for biochemical recurrence (0.15 ≤ PSA \<0.70 ng/ml) after prostatectomy.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Continued salvage radiotherapy + lymph node irradiation (non responders)

Continued salvage radiotherapy as initially planned (to 70.0 Gy/73.5 Gy in 35 fractions to the prostate bed/local recurrence if present) + the addition of lymph node irradiation (46 Gy/23 fractions) given in sequence. Total number of fractions: 35 + 8 = 43 with 15 of the lymph node irradiation fractions delivered concomitant with the prostate bed/local recurrence irradiation. These patients are classified as non responders according to weekly PSA measurements during the first 4 weeks of radiotherapy.

Group Type EXPERIMENTAL

Radiation to the prostate bed with or without addition of radiation of lymph node irradiation.

Intervention Type RADIATION

Radiation to the prostate bed with or without addition of radiation of lymph node irradiation (non responders). Patients with PSA response continues radiotherapy as initially planned, and are not followed according to the study protocol, only according to clinical practice.

Continued salvage radiotherapy (non responders)

Continued salvage radiotherapy as initially planned (to 70.0 Gy/73.5 Gy in 35 fractions to the prostate bed/local recurrence if present). These patients are classified as non responders according to weekly PSA measurements during the first 4 weeks of radiotherapy.

Group Type ACTIVE_COMPARATOR

Radiation to the prostate bed with or without addition of radiation of lymph node irradiation.

Intervention Type RADIATION

Radiation to the prostate bed with or without addition of radiation of lymph node irradiation (non responders). Patients with PSA response continues radiotherapy as initially planned, and are not followed according to the study protocol, only according to clinical practice.

Continued salvage radiotherapy (responders)

Continued salvage radiotherapy as initially planned (to 70.0 Gy/73.5 Gy in 35 fractions to the prostate bed/local recurrence if present). These patients are classified as responders according to weekly PSA measurements during the first 4 weeks of radiotherapy, and are not followed according to the study protocol, follow up according to clinical practice.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Age ≥18 years.
* World Health Organization (WHO) performance status 0-1.
* Estimated life expectancy \>10 years.
* Histological evidence of prostate cancer in the prostatectomy specimen
* Primary tumor, regional nodes, metastasis (TNM): any primary tumor (pT), pathologically node-negative (pN0), M0.
* Biochemical Recurrence (BCR) after prostatectomy, with 0.15 ≤ PSA \<0.70 ng/ml.
* Patients must be able to comply with the protocol.
* Signed informed consent.
* Adequate laboratory findings (Haemoglobin (Hb) \>90g/L, absolute neutrophil count \>1.0x109/L, platelets \>75x109/l, bilirubin \<1.5x upper limit of normal (ULN), alanine aminotransferase (ALAT) \<5x ULN and creatinine \<1.5 ULN).

Exclusion Criteria

* Metastases (regional lymph nodes or distant)\* diagnosed with imaging.
* Prior or ongoing hormonal therapy (antiandrogens or gonadotropin releasing hormone).
* Prior radiotherapy to the pelvis.
* Prior malignancy other than prostate cancer and basalioma in the past five years.
* Clinically significant (i.e. active) cardiovascular disease e.g. myocardial infarction (≤6 months), unstable angina, New York Heart Association (NYHA) class III-IV congestive heart failure.
* Severe pulmonary disease.
* Any other serious or uncontrolled illness which in the opinion of the investigator makes it undesirable for the patient to enter the trial.
