About this study

The purpose of this study is to evaluate the effectiveness of the two most established primary treatments for patients with clinically localized prostate cancer: radical retropubic prostatectomy, and external-beam radiotherapy. The primary aim is assessing biochemical disease-free survival, overall survival, and prostate cancer-specific survival. As secondary objectives quality of Life impact of treatments' side effects will be also assessed.

Read the detailed description

Eligible patients had clinically localized (clinical TNM classification T1 or T2), biopsy-proven adenocarcinoma of the prostate and were randomly treated with RRP or EBRT. Exclusion criteria included prior treatment for prostate cancer, the presence of metastatic disease on imaging studies, the receipt of neoadjuvant androgen ablation before registration, and an inability to read or understand Italian language. The institutional review boards of every participating centre approved the study design. Every patient enrolled signed an informed-consent form approved by the institutional review boards. Clinical information collected from the medical record included pre-treatment serum prostate-specific antigen (PSA) level, clinical T classification, and biopsy Gleason score. Follow-up assessments were completed before treatment and every 3 months after treatment. Subjects who sought primary treatment elsewhere or did not return follow-up questionnaires beyond the initial assessment were excluded from this analysis.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Radical retropubic prostatectomyProcedure or surgery

    The surgery arm underwent radical retropubic prostatectomy, performed by a technique described by Walsh. The prostatectomy is performed in retrograde way, preserving the neurovascular bundles if feasible. The degree to which the surgeon preserve the nerves is categorized as non-nerve-sparing, unilateral nerve-sparing, or bilateral nerve-sparing. Pelvic lymph node dissection is performed if feasible. The operative time is about 2 to 3 hours and required hospital stay. The patient has a urinary catheter placed for 6 to 9 days to facilitate bladder emptying.

  • External beam radiotherapyRadiation

    External beam radiotherapy is carried out with intensity-modulated radiation technique. The treatment is designed to maximize the radiation dose to the prostate and seminal vesicles and minimize exposure to surrounding structures, including the bladder and rectum. Radiation to the prostate was delivered in fractionated doses divided over multiple treatments (180 to 200 centigray (cGy) daily fractions, 5 days per week) for a total dose to the prostate of 68 to 77 gray (Gy), prescribed at 90% to 100% of the isodose line.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Biochemical disease-free survival

    Number of participants who are free of biochemical relapse after a specified duration of time. Biochemical recurrence is measured by PSA levels. The definition of biochemical recurrence was based on a review of the literature and consideration of clinical practice in the year 1997. Biochemical recurrence among patients who underwent radical prostatectomy (RP) was defined as a measurable serum PSA concentration 0.2 ng/ml or greater. The American Society for Therapeutic Radiology and Oncology (ASTRO) criteria were used to define progression after radiation therapy. The ASTRO consensus definition specifies progression as 3 consecutive increases in serum PSA documented at intervals of 6 or more months.

    Measured: up to 12 months

Secondary outcomes (6)
  1. •Perceived general health measured by the Medical Outcomes Study 36-Item Short Form (SF-36).

    The Medical Outcomes Study 36-Item Short Form (SF-36) version 2 contains 36 items covering eight dimensions: physical functioning, role limitations due to physical health problems, bodily pain, general health, vitality, social functioning, role limitations due to emotional problems and mental health. For each dimension, a score ranges from 0-100 (higher score indicate better health).Physical and mental component summaries are constructed, using recommended scoring algorithms. Summary scores are standardized to have a mean of 50 and standard deviation of 10 in the general population.

    Measured: 1, 3, 6, 12 and 24 months after treatment.

  2. •Cancer specific Quality of Life measured by the Functional Assessment of Cancer Therapy - General and Prostate specific - (FACT-G and FACT-P, respectively).

    The Functional Assessment of Cancer Therapy - General (FACT-G) version 4.0 was designed to measure Quality of Life in cancer patients. It consists of 27 items in 4 dimensions measuring Physical, Social/familial, Emotional, and Functional well-being. The Prostate module (FACT-P) is specific for patients with prostate cancer and contains 12 questions about urinary symptoms, and bowel and sexual function. Scores range from 0 to 108 on the FACT-G, and from 0 to 48 on the FACT-P, with 0 representing perfect health.

    Measured: 1, 3, 6, 12 and 24 months after treatment.

  3. •Urinary symptoms measured by the International Prostate Symptom Score (IPSS).

    The International Prostate Symptom Score (IPSS) was developed to assess the severity of lower urinary tract symptoms associated to Benign Prostatic Hyperplasia and has also been applied to other conditions that cause lower urinary tract symptoms (LUTS). The IPSS consists of a total of seven questions that deal with voiding symptoms (incomplete empty, intermittency, weak stream and straining to void) and storage symptoms (frequency, urgency and nocturia) and an additional question to measure quality of life. The score ranges from 0 to 35, with lower scores denoting a better health state.

    Measured: 1, 3, 6, 12 and 24 months after treatment.

  4. •Sexual symptoms measured by the International Index of Erectile Function (IIES).

    The International Index of Erectile Function (IIES) is a 15-item, self-administered questionnaire scale for the assessment of erectile function. Scores range from 5 to 75, with higher scores denoting a better sexual function.

    Measured: 1, 3, 6, 12 and 24 months after treatment.

  5. Overall survival.

    Number of participants who are alive after a specified duration of time.

    Measured: 5, 7 and 10 years after treatment and every 5 years thereafter.

  6. Prostate cancer-specific survival

    Number of participants who are not dead due to prostate cancer after a specified duration of time

    Measured: 3, 5, and 10 years after treatment and then every 5 years thereafter

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Radical retropubic prostatectomy and External beam radiotherapy in people with Prostate Cancer, run by University of Rome Tor Vergata.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: paused, as of the sponsor's last update on 25 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Biochemical disease-free survival (time frame: up to 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Mar 2020.
