Hypofractionation With Simultaneous Integrated Boost for Early Breast Cancer

August 19, 2021 updated by: Juergen Dunst, Prof., University Hospital Schleswig-Holstein

Multicenter Phase-II-Trial of Evaluation of Acute Toxicity in Hypofractionation With Simultaneous Integrated Boost for Early Breast Cancer

Hypofractionation with simultaneous integrated boost has been investigated in a few trials and appears to be safe and feasible with less lung toxicity in smaller studies.

Investigators initiated this multicenter phase II prospective trial to analyse acute toxicity of hypofractionation with simultaneous integrated boost in patients with early breast cancer under the hypothesis that the ratio of patients with acute radiogenic toxicity Grad II according NCI-CTCAE amounts maximum 20%.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

  • Pre- and/or postoperative chemotherapy and endocrine therapy were permitted when indicated
  • Written informed consent

Exclusion Criteria:

  • Patients operated by mastectomy
