SUCLANODE: Medial vs. Entire Supraclavicular Lymph Node Radiation Therapy for Patients With Invasive Breast Cancer
Study Details
Study Description
Brief Summary
Locally advanced breast cancer has high-risk local regional recurrence after surgery. Radiotherapy could reduce the local regional recurrence and improve disease free survival and overall survival. Regional lymph node irradiation is the important part of breast cancer radiotherapy. However, there are some controversies about regional lymph node delineation, especially the supraclavicular irradiation volume. Many studies had confirmed that posterolateral region of the supraclavicular fossa (also named Posterior neck lymph node) had a high risk involvement based on the mapping of recurrence nodes. This randomized phase III trial compares medial supraclavicular lymph node irradiation with entire supraclavicular lymph node irradiation in patients with pathologically positive axillary lymph node and high risk of recurrence after mastectomy or breast conservative surgery. It is not yet known if radiation works better with entire supraclavicular fossa than medial supraclavicular fossa.

Detailed Description
PRIMARY OBJIECTIVE:
- To evaluate whether entire supraclavicular lymph node irradiation is superior to medial supraclavicular lymph node irradiation in terms of disease free survival for patients with positive lymph nodes and high risk of recurrence after breast cancer surgery
SECONDARY OBJECTIVES:
- To estimate the difference of overall survival II. to estimate the difference of ipsilateral supraclavicular node recurrence III. to estimate the difference of local regional recurrence IV. to estimate the difference of radiation related toxicities and quality of life.
Outline: Beginning 2-12 weeks after the completion of breast cancer surgery and neoadjuvant/adjuvant chemotherapy, patients are randomized to 1 of 2 treatment arms Arm I: Patients undergo breast/chest wall, undissected axillary, internal mammary node and medial supraclavicular node radiation. Conventional fractionated radiotherapy 50Gy/25Fx/5w or hypofractionated 42.5Gy/16Fx/3.5week with IMRT or VAMT technique is recommended. 3DCRT technique is not permitted.
Arm II: Patients undergo breast/chest wall, undissected axillary, internal mammary node and entire supraclavicular node radiation. Conventional fractionated radiotherapy 50Gy/25Fx/5w or hypofractionated 42.5Gy/16Fx/3.5week with IMRT or VAMT technique is recommended. 3DCRT technique is not permitted
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: Breast/chest wall+undisseted axillary+IMN+medial SCL ( medial SCL radiation) Radiation is delivered to the breast/chest wall, undissected axilla, internal mammary nodes and medial supraclavicular node. Treatment will be given by normfractionated or hypofractionated radiotherapy (50Gy/25Fx/5w or 42.5Gy/16Fx/3.5w). IMRT and VMAT technique are recommended. |
Radiation: Medial supraclavicular lymph node radiotherapy
Radiation is delivered to the breast/chest wall, undissected axilla, internal mammary nodes and entire supraclavicular lymph node.
|
| Experimental: Breast/chest wall+undisseted axillary+IMN+entie SCL (entire SCL radiation) Radiation is delivered to the breast/chest wall, undissected axilla, internal mammary nodes and entire supraclavicular node. Treatment will be given by normfractionated or hypofractionated radiotherapy (50Gy/25Fx/5w or 42.5Gy/16Fx/3.5w). IMRT and VMAT technique are recommended. |
Radiation: Entire supraclavicular lymph node radiotherapy
Radiation is delivered to the breast/chest wall, undissected axilla, internal mammary nodes and entire supraclavicular lymph node. Entire supraclavicular lymph node includes medial supraclavicular and posterior neck lymph node.
