Intensity Modulated Radiation Therapy (IMRT) Pelvic Nodes Prostate

December 5, 2023 updated by: University Health Network, Toronto

A Phase I/II Study of Dose Escalated Intensity Modulated Radiation Therapy (IMRT) for the Treatment of Pelvic Lymph Nodes and Primary Tumour in Patients With Carcinoma of the Prostate

The purpose of this study is to determine the feasibility and late toxicity of dose escalated radiation therapy to the pelvic lymph nodes and prostate and seminal vesicles in the treatment of high risk prostate cancer. All eligible patients with high risk prostate cancer who are going to have primary radiation therapy to the pelvic lymph nodes and prostate seminal vesicles with or without concurrent hormonal therapy will be approached regarding study entry.

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.

Detailed Description

Prostate cancer is now the most commonly diagnosed cancer in Canadian men and is the third most common cause of cancer death.1 Locally advanced prostate cancer (clinical T3/T4) is uncommon in North America because of earlier diagnosis following widespread PSA testing and patient information campaigns. However, in the past decade the term high-risk prostate cancer has been developed to include the previous locally advanced disease and patient with T1/T2 disease with poor prognostic features (either a high Prostate Specific Antigen or high Gleason score). The risk of involvement of pelvic lymph nodes by prostate cancer for certain subgroups of intermediate risk and most high risk prostate cancer may be substantial. The long term results of conventional dose (66-70 Gy) external beam radiation therapy for intermediate and locally advanced prostate cancer have been disappointing. The combination of hormonal therapy and radiation therapy or radiation therapy dose escalation are the two strategies which have been evaluated and are now used to improve these results.

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.

Ages Eligible for Study

No older than 80 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • A histologic diagnosis of adenocarcinoma of the prostate within six months of entry.
  • Clinical Stage T1-T2 with (PSA >20 or Gleason score >7)
  • Clinical Stage T3, T4
  • Bone scan reported as negative for metastases within 6 months of study entry.
  • All patients must have a CT scan of the abdomen and pelvis reported as negative for nodal metastases within 12 wks of study entry.
  • The patient must not have received greater than 6 months of hormonal therapy.
  • The patient must not have received cytotoxic anticancer therapy prior to study entry.
  • Patients must have an ECOG performance status of 2 or less.
  • Age 80 years old or less
  • Signed informed consent

Exclusion Criteria:

  • Patients with history of inflammatory bowel disease or other contraindication to radical radiation therapy
  • Patients with prior colorectal surgery
  • Patients with prior or active malignancy except non-melanoma skin carcinoma within 5 years of the diagnosis of prostate cancer

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: IMRT in prostate cancer
Radiation: Dose Escalated IMRT
Patients will receive external beam RT 55.1Gy in 29 once daily fractions to pelvic lymph nodes/prostate/seminal vesicles followed by 24.7Gy in 13 once daily fractions to the prostate/seminal vesicles using intensity modulated radiation therapy.

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
Time Frame
Determine the feasibility and late toxicity of dose escalated radiation therapy to the pelvic lymph nodes and prostate and seminal vesicles in the treatment of high risk prostate cancer.
Time Frame: after all patients have completed study intervention
after all patients have completed study intervention

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.
Outcome Measure
Time Frame
acute toxicity of therapy;prostate motion when pelvic radiotherapy is delivered;treatment time required to deliver IMRT to the pelvic lymph nodes, prostate and seminal vesicles
Time Frame: after all patients have completed study intervention
after all patients have completed study intervention
