Brief Summary

The "Hyperbaric OxygeN therapy on brEast cancer patients with late radiation toxicity" (HONEY) trial aims to evaluate the effectiveness of HBOT on late radiation toxicity in breast cancer patients using the trial within cohorts (TwiCs) design.

Outcome Measures

Primary Outcomes (1)

  • Change in breast/chest wall pain: EORTC QLQ-BR23 questionnaire

    The primary endpoint of this study is the difference in proportion of patient-reported breast/chest wall pain grade 3-4 between control and intervention group. Pain is assessed by means of the EORTC QLQ-BR23 questionnaire on a 4-point Likert scale. At baseline all patients have a pain score of 3 or 4 (see inclusion criteria). The proportion of patients with 3-4 at 6 months will be compared between intervention and control group. A higher score indicates more pain.

    Baseline and 6 months after baseline (i.e. 3 months after HBOT)

Secondary Outcomes (7)

  • Change in patient-reported quality of life: (EORTC QLQ) C30

    Baseline and 6 months after baseline (i.e. 3 months after HBOT)

  • Change in patient-reported late radiation toxicity

    Baseline and 6 months after baseline (i.e. 3 months after HBOT)

  • Physician-reported late radiation toxicity

    Baseline (prior to HBOT), 3 months after baseline (i.e. after HBOT) and 6 months after baseline (i.e. 3 months after the last HBO session)

  • Patient-reported cosmetic outcome

    Baseline and 6 months after baseline (i.e. 3 months after HBOT)

  • Physician-reported cosmetic outcome

    Baseline and 6 months after baseline (i.e. 3 months after HBOT)

  • +2 more secondary outcomes

Study Arms (2)

Hyperbaric oxygen therapy

EXPERIMENTAL

Hyperbaric oxygen therapy consists of 30-40 treatment sessions (1 session per day during 5 days per week). During the hyperbaric oxygen (HBO) sessions the pressure will be raised to 2.4 atmospheres absolute in a hyperbaric chamber and patients breath in 100% oxygen during 4 times 20 minutes.

Drug: Hyperbaric oxygen therapy

Usual care

NO INTERVENTION

Usual care may consist of physiotherapy, analgetics, edema therapy

Interventions

Hyperbaric oxygen therapy in a multiperson hyperbaric oxygen chamber. Standard hyperbaric oxygen therapy provided as reimbursed by insurers.

Eligibility Criteria

Age18 Years+
Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Self reported pain grade 3-4 (on a scale of 1-4) as assessed by the late radiation toxicity questionnaire;
  • Participation \>12 months in the UMBRELLA cohort;
  • Previous treatment with radiotherapy for breast cancer;
  • Completed surgery and (neo)adjuvant systemic therapy except adjuvant endocrine therapy, for breast cancer.

You may not qualify if:

  • Poor responder to questionnaires (i.e. return of ≤ 2 UMBRELLA questionnaires);
  • Previous HBOT;
  • Contra-indications for HBOT (e.g. (severe) chronic obstructive pulmonary disease (COPD) or asthma, pacemaker, morbid obesity, epilepsy in medical history, severe heart failure);
  • Current metastatic disease or recurrent breast cancer.
  • Inability to follow schedule of all consecutive HBO treatments (e.g. due to scheduled holidays \> 2 days);
  • Not meeting criteria for HBOT (e.g. due to complaints similar to late radiation toxicity, not caused by radiotherapy).
