Phase I Study of Hyperthermia Combined With High Dose Rate Salvage Radiotherapy for the Treatment of Radiation Recurrent Prostate Cancer

Condition: Recurrent Prostate Carcinoma

Intervention:

  • Radiation: High-Dose Rate Brachytherapy
  • Procedure: Hyperthermia Treatment

Purpose: This phase I trial studies the side effects and best way to give hyperthermia and high dose rate radiation therapy in treating patients with prostate cancer that has come back after prior radiation treatment. Radiation therapy, such as high dose rate brachytherapy, uses radioactive material placed directly into or near a tumor to kill tumor cells. Hyperthermia therapy may make tumor cells more sensitive to the effects of radiation therapy by heating them to several degrees above normal body temperature. Giving hyperthermia and high dose rate radiation therapy may work better in treating patients with recurrent prostate cancer after radiation.

Study Type: Interventional

Clinical Trials Identifier NCT 8-digits: NCT02899221

Sponsor: Sidney Kimmel Cancer Center at Thomas Jefferson University

Primary Outcome Measures:

  • Measure: Incidence of dose limiting toxicity defined as >= grade 3 per National Cancer Institute Common Toxicity Criteria version 4 occurring within 90 days of treatment and at least possibly attributed to radiation therapy and/or hyperthermia
  • Time Frame: Up to 90 days after last treatment
  • Safety Issue:

Secondary Outcome Measures:

  • Measure: Incidence of long-term toxicity associated with combined salvage high dose rate brachytherapy and interstitial hyperthermia
  • Time Frame: Up to 5 years after last treatment
  • Safety Issue:
  • Measure: Efficacy of combined salvage high dose rate brachytherapy and interstitial hyperthermia as defined by nadir PSA(prostate-specific antigen) =< 0.5 mg/ml and freedom from biochemical failure per the Phoenix definition (nadir + 2)
  • Time Frame: Up to 5 years after last treatment
  • Safety Issue:

Estimated Enrollment: 10

  • Histologically proven persistent or recurrent adenocarcinoma of the prostate following prior external beam radiation therapy or brachytherapy
  • Prior Androgen Deprivation or chemotherapy is allowed if discontinued at least 30 days prior to enrollment
  • Concurrent disease
  • patients under treatment for concurrent medical conditions will be eligible for protocol treatment if, in the opinion of the physician responsible for hyperthermia treatment that the concurrent medical condition will neither interfere with the process of the treatment or patient assessments nor add significantly to the risks or complications of the treatment

Exclusion Criteria:

  • History of urological surgery or procedures predisposing to genitourinary (GU) complications after radiation, i.e., anastomoses, stricture repair, transurethral resection, etc. (will be determined by radiation oncologist)
  • Prior thermal ablative therapy for prostate cancer (e.g. high-intensity focused ultrasound [HIFU] or cryoablation)
  • Documented distant metastatic disease
  • Patient with other co-morbidities that in the opinion of the treating physician would be a contra-indication to protocol participation (e.g. inflammatory bowel disease)
  • Mental incompetence or criminal incarceration
