Study Details

Study Description

Brief Summary

The standard treatment of localized breast cancers consists of surgical removal of the tumor at the breast or removal of the entire breast and lymph nodes (sentinel lymph node and / or axillary dissection) with or without chemotherapy followed by radiotherapy on the breast or thoracic wall and the lymph node areas from 5 to 6.5 weeks.

Shorter radiotherapy treatments over 3 weeks for breast cancer without lymph node involvement have been equally effective and have no more side effects in several clinical trials involving several thousand patients. This called hypofractionated radiotherapy has become a standard for breast cancers in the absence of lymph node involvement in postmenopausal women.

The objective of the HypoG01 trial is to evaluate hypofractionated radiotherapy in women who require radiotherapy in the breast or chest wall and lymph node areas by comparing standard over 5 to 6.5 weeks and hypofractionated irradiation over 3 weeks analyzing the possible side effects and in particular the risk of lymphedema (swelling of the arm on the side treated) and the effectiveness of these treatments

    50 Gy / 25 fractions, 2.0 Gy per fraction, 5 fractions per week. If the patient is candidate for a boost it will be provided as follows: sequential boost with 50 Gy to CTV breast in 25 fractions and 16 Gy to CTV boost in 8 fractions or simultaneous integrated boost (SIB) with 51.52 Gy on CTV breast and 63 Gy on CTV boost in 28 fractions

  • Standard Arm
  • Outcome Measures

    Primary Outcome Measures

    1. Arm Lymphedema [Before treatment, week 3 or week 7 of treatment according the treatment arm and boost realization, 6 months after the last fraction received, every year during 5 years, 10 years]

      Change from baseline ratio of the circumference (cm) of the treated side and contralateral side at week 3 or week 7 of treatment (according the treatment arm and boost realization), and during follow-up (6 months after the last fraction received, every year during 5 years, 10 years)

    Secondary Outcome Measures

    1. Functional Assessment [Before treatment, week 3 or week 7 of treatment according the treatment arm and boost realization, 6 months after the last fraction received, every year during 5 years, 10 years]

      Flexion/abduction of the upper arm will be assessed.

    2. Aesthetics Assessment-FIBROSIS [Before treatment, week 3 or week 7 of treatment according the treatment arm and boost realization, 6 months after the last fraction received, every year during 5 years, 10 years]

      Fibrosis as tissue induration, telangiectasia, oedema of the breast/chest wall and dyspigmentation will be evaluated according the LENT-SOMA scoring scale.

    3. Aesthetics Assessment-BIS SCORE [Before treatment, week 3 or week 7 of treatment according the treatment arm and boost realization, 6 months after the last fraction received, every year during 5 years, 10 years]

      The patient evaluates satisfaction on The Body Image Score (BIS) where has been added an extra question regarding clothing habits and furthermore based on the study by Lyngholm et al also 2 more questions regarding the satisfaction with the appearance of the treated breast after breast conservation with and without comparison to the opposite breast as done in the DBCG HYPOII trial. In addition, it will ask if the patient treated with breast conservation has had lipo-feeling injection in the breast during follow up.

    4. Aesthetics Assessment-Global Cosmestic [Before treatment, week 3 or week 7 of treatment according the treatment arm and boost realization, 6 months after the last fraction received, every year during 5 years, 10 years]

      The global cosmetic result after breast conservation will be based on Harris´ 4-point scale modified by Rune Gärtner et al

    5. CTCAE Toxicity Assessment [Before treatment, every week of treatment, week 3 or week 7 of treatment according the treatment arm and boost realization, 6 months after the last fraction received, every year during 5 years, 10 years]

      Acute/ late toxicity will be assessed according to the flowchart and performed based on CTCAE V4

    6. RTOG/EORTC Toxicity Assessment [Before treatment, every week of treatment, week 3 or week 7 of treatment according the treatment arm and boost realization, 6 months after the last fraction received, every year during 5 years, 10 years]

      Acute/ late toxicity will be assessed according to the flowchart and performed based on Toxicity Criteria of RTOG/EORTC

    7. Cancer Related events [6 months after the last fraction received, every year during 5 years, 10 years]

      Cancer related endpoints are secondary endpoints in this trial. It's a composite outcome taking into account all relapse events (locoregional, invasive disease, distant disease), breast-cancer specific survival, and causes of death as defined per DATECAN guidelines. All time to cancer related endpoints are defined as starting from the date of randomization until the event.

    8. Cost-Utility [Week 3 or week 7 of treatment according the treatment arm and boost realization]

      A cost-utility analysis comparing radiotherapy regimens will be performed based on QALYs

    9. Quality of Life QLQ-C30 [Before treatment, week 3 or week 7 of treatment according the treatment arm and boost realization, 6 months after the last fraction received, every year during 5 years, 10 years]

      Patients' quality of life will be assessed using self-administered questionnaire EORTC QLQ-C30

    10. Quality of Life EORTC BR23 [Before treatment, week 3 or week 7 of treatment according the treatment arm and boost realization, 6 months after the last fraction received, every year during 5 years, 10 years]

      Patients' quality of life will be assessed using self-administered questionnaire EORTC BR23

    11. Quality of Life Euroqol EQ-5D5D [Before treatment, week 3 or week 7 of treatment according the treatment arm and boost realization, 6 months after the last fraction received, every year during 5 years, 10 years]

      Patients' quality of life will be assessed using self-administered questionnaire Euroqol EQ-5D5D
