Radiation Therapy With RapidPlan Knowledge-based Planning vs Human-Driven Planning for Treatment of Prostate Cancer

Summary

This phase III trial compares the effects of radiation therapy using RapidPlan, trademark, knowledge-based planning to human-driven planning in treating patients with prostate cancer. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill tumor cells and shrink tumors. Successful delivery of radiation requires planning to develop a treatment plan for how and where the radiation is to be delivered. RapidPlan is a knowledge-based treatment planning tool that automatically creates an optimal treatment plan based on identified targets and organs at risk for radiation exposure. Human-driven treatment planning by a dosimetrist, the current standard of care, requires significant resources and time and may vary within and among radiation centers. Giving radiation therapy with RapidPlan knowledge-based planning may have similar or less side effects compared to human-driven planning in treating patients with prostate cancer.

Eligibility

Inclusion Criteria:

* Patients must be at least 18 years old
* Histologically confirmed prostate cancer
* Clinical or pathologic stages T1c-T3b, Nx or N0-1, M0-1 (American Joint Committee on Cancer \[AJCC\] criteria 8th edition \[Ed\])
* Planned definitive dose radiotherapy to the prostate or prostate bed
* Eastern Cooperative Oncology Group (ECOG) performance status 0-2 assessed within 90 days of enrollment
* Patients must sign Institutional Review Board (IRB) approved study specific informed consent
* Patients must complete all required pre-entry tests within the specified time frames
* Patients must be able to start treatment (radiation) within 180 days of study registration
* In case of confusion about the eligibility or ineligibility of an individual patient, the principal investigator (PI) can be used as the arbiter and a note to file will be added to the subject's regulatory binder to document outcome

Exclusion Criteria:

* Previous pelvic radiation \> 5 Gy
* Planned delivery of radiotherapy to pelvic lymph nodes
* Planned delivery of brachytherapy of the prostate
* Active rectal diverticulitis, Crohn's disease affecting the rectum, or ulcerative colitis (non-active diverticulitis and Crohn's disease not affecting the rectum are allowed)
* Prior hip replacement or penile implant
* Major medical, addictive, or psychiatric illness which in the investigator's opinion, will prevent the consent process, completion of the treatment and/or interfere with follow-up. (consent by legal authorized representative is not permitted for this study)
* Indwelling or intermittent urinary catheter use
