Combined, Intensified and Modulated Adjuvant Therapy in Prostate Carcinoma

Combined, Intensified and Modulated Adjuvant Therapy in Prostate Carcinoma: a Phase II Trial

Patients with high risk prostate cancer may benefit from radiotherapy after radical prostatectomy. The investigators postulated that adjuvant androgen deprivation therapy (ADT), radiation dose escalation, and selective pelvic irradiation may improve outcome. A phase II trial was designed to prove that combined-intensified-modulated-adjuvant (CIMA) treatment may improve 5-year biochemical relapse free survival (bRFS) from 75% to 90% in high risk patients. The delivered dose to tumor bed and pelvic nodes was 64.8-70.2 Gy and 45 Gy (57% of patients), respectively, and 69% received ADT.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Prostate cancer patients at high risk of loco-regional recurrences may benefit from postoperative radiotherapy (RT) following radical prostatectomy (EORTC trial 22911). However, despite an improvement in biochemical relapse-free survival (bRFS), the risk of recurrences remained high for those patients. The investigators postulated that adjuvant androgen deprivation therapy (ADT), radiation dose escalation, and selective pelvic irradiation for patients at risk for regional failures may improve the outcome. The combined-intensified-modulated-adjuvant (CIMA) as described may improve survival through a reduction of loco-regional and systemic failures.

A phase II trial was designed to test the hypothesis that CIMA treatment may improve 5-year bRFS by 15%. Patients less than 80 years old, with a histological diagnosis of prostate adenocarcinoma without distant metastases, stage pT2-4 N0-1, no previous treatments and an ECOG performance status of 0-2 were selected. All patients had at least one of these pathologic features: extracapsular extension, positive surgical margins, or seminal vesicle invasion. Radiation dose to the tumor bed ranged from 64.8 to 70.2 Gy. Pelvic lymph nodes were treated to 45 Gy in selected patients at risk of regional failures (57%). Selected patients at risk for distant metastases (69.1%) received hormonal therapy.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

OTHER: intensified and modulated adjuvant RT
All patients underwent combined, intensified and modulated adjuvant radiotherapy for 5 days a week with the following doses: 1) pelvic node irradiation (45 Gy; 1.8 Gy/fraction) followed by boost on the prostate bed (19.8-25.2 Gy; 1.8 Gy/fraction; total dose: 64.8-70.2 Gy) or 2) exclusive prostate bed irradiation (64.8 -70.2 Gy; 1.8 Gy/fraction).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Biochemical relapse free survival
Time Frame: Five years
Survival free from increase of PSA level exceeding 0.2 ng/mL for those with postsurgical PSA level of 0.2 ng/mL or lower, and as two consecutive PSA increases for patients with a postsurgical PSA level of > 0.2 ng/ml
Five years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
