 (submitted: December 18, 2018)
Tumor Assessment [ Time Frame: 24 months ]
Tumors will be assessed using the American Joint Committee on Cancer (AJCC) Staging System, 7th Edition. This system consists of the following subscales: the extent of the primary tumor (T category), whether the cancer has spread to nearby lymph nodes (N category), the absence or presence of distant metastasis (M category), the PSA level at the time of diagnosis, and the Gleason score, based on the prostate biopsy (or surgery).

Descriptive Information
Brief Title  ICMJE Stereotactic Boost and Long-Term Androgen Deprivation for Adenocarcinoma of the Prostate
Official Title  ICMJE Whole-Pelvic Radiotherapy With a Stereotactic Body Radiotherapy Boost and Long-Term Androgen Deprivation for Unfavorable-Intermediate and High Risk Localized Adenocarcinoma of the Prostate.
Brief Summary

We hypothesize that Stereotactic Body Radiotherapy Boost (SBRT) as a boost to the prostate following whole pelvic intensity modulated radiotherapy (IMRT) can be delivered effectively and safely in a population of men with unfavorable intermediate and high risk localized prostate cancer.

Our primary objective is to assess the feasibility and safety of a treatment strategy incorporating whole pelvic IMRT followed by an SBRT boost to the prostate with neoadjuvant, concurrent, and adjuvant androgen deprivation for a total of 28 months for men with unfavorable intermediate or high risk localized prostate cancer.

Detailed Description

The primary objective of this study is to assess the feasibility and safety of a treatment strategy incorporating whole pelvic IMRT followed by an SBRT boost to the prostate with neoadjuvant, concurrent, and adjuvant androgen deprivation for a total of 28 months for men with unfavorable intermediate or high risk localized prostate cancer.

The secondary objective is to assess biochemical control at 24 months following the experimental treatment strategy by the "Phoenix definition". Patients not meeting these prostate-specific antigen (PSA) criteria (Phoenix Definition) for failure who undergo salvage therapies (such as androgen deprivation therapy (ADT), radical prostatectomy or brachytherapy, or Cryosurgery) should also be declared as failures at the time a positive biopsy is obtained or salvage therapy is administered, whichever comes first.

Another secondary objective is to assess toxicity of the experimental treatment approach as scored by the Common Terminology Criteria for Adverse Events The third secondary objective is to assess prostate organ motion during hypofractionated radiotherapy. To assess motion of the prostate during the protracted delivery of hypofractionated radiotherapy as assessed by implanted electromagnetic transponder beacons.

Eligibility Criteria  ICMJE

Inclusion Criteria:

  1. Pathologically (histologically or cytologically) proven diagnosis of prostatic adenocarcinoma within 180 days of registration at moderate to high risk for recurrence
  2. History/physical examination (to include at a minimum digital rectal examination of the prostate and examination of the skeletal system and abdomen) within 90 days prior to registration.
  3. Clinically negative lymph nodes as established by imaging (pelvic ± abdominal CT or MRI), (but not by nodal sampling, or dissection) within 90 days prior to registration.
  4. Patients with lymph nodes equivocal or questionable by imaging are eligible if the nodes are ≤ 2.0 cm.
