Brief Summary:
This study aims to compare patients that receive hyperbaric oxygen or Trental and Vitamin E immediately after completion of radiation therapy to evaluate which treatment best reduces radiation fibrosis.

Condition or disease Intervention/treatment Phase
Breast Cancer Procedure: Hyperbaric Oxygen Therapy Drug: Trental Pill Dietary Supplement: Vitamin E Phase 2

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 60 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Prevention
Official Title: A Pilot Study Comparing Acute Post-Radiation Hyperbaric Oxygen (HBO2) Versus Trental and Vitamin E for Breast Cancer Patients Who Have Recently Completed Radiation Therapy as Part of Their Treatment Course
Actual Study Start Date : July 1, 2019
Estimated Primary Completion Date : May 1, 2023
Estimated Study Completion Date : May 1, 2024

Arm Intervention/treatment
Experimental: Hyperbaric Oxygen Therapy
Hyperbaric oxygen (HBO2) - 100% oxygen at 2.4 atmospheres ATA for 90 minutes, Monday-Friday for 30 sessions (six weeks)
Procedure: Hyperbaric Oxygen Therapy
Hyperbaric oxygen therapy at 2.4 atmospheres for 90 minutes for 30 sessions.

Active Comparator: Trental and Vitamin E
Trental (pentoxifylline), 400 milligrams three times a day in combination with Vitamin E, 400 international units orally twice daily for six months
Drug: Trental Pill
Trental 400 mg three times daily, in combination with Vitamin E 400 IU twice daily
Other Name: pentoxifylline

Dietary Supplement: Vitamin E
Vitamin E 400 IU twice daily, in combination with Trental 400 mg three times daily

Primary Outcome Measures :
  1. Change in breast fibrosis using Bakers Grade Assessment [ Time Frame: Administered at week 1, week 7, week 13, week 25, week 53, and week 157. ]
    The Bakers Grade Assessment will be used to evaluate if lower incidence and severity of radiation fibrosis is observed in patients receiving post-operative hyperbaric oxygen treatment as compared to Trental and Vitamin E. The difference-from-baseline (DFB) score will be calculated to determine the incidence and severity of radiation fibrosis. Some patients may develop radiation fibrosis at a later time so the assessment will be done multiple throughout the three years to capture timing of fibrosis onset.

Secondary Outcome Measures :
  1. Objective measurements of tissue pliability using a Tissue Compliance Meter [ Time Frame: Obtained at week 1, week 7, week 13, week 25, week 53, and week 157. ]
  2. Patients' sense of well-being using SF-20 Quality of life survey. [ Time Frame: Administered at week 1, week 7, week 13, week 25, week 53, and week 157. ]
    Short Form 20 is a survey that patients complete to indicate their overall quality of life. The SF-20 is weighted and summed to provide easily interpretable scales for physical and mental health.

  3. Pain in radiated breasts using a Visual Analog Scale [ Time Frame: Administered at week 1, week 7, week 13, week 25, week 53, and week 157. ]
    Visual Analog Scale is a way for patients to assess their pain, on a scale of one to ten with ten being worst pain imaginable.

  4. Presence of delayed wound healing, surgical complications, implant revision or loss [ Time Frame: Evaluated at week 1, week 7, week 13, week 25, week 53, and week 157. ]
