[A clinical study of 214 cases of modified radical mastectomy with preservation of major and minor pectoral muscles].

Objective: To study clinical effects of modified radical mastectomy with preservation of major and minor pectoral muscles.

Methods: A retrospective analysis was carried out in 214 cases of breast cancer patients (including stage I 66 cases, stage II 141 cases and stage III 7 cases). Modified radical mastectomy with preservation of major and minor pectoral muscles was performed on all the patients.

Results: Out of 214 cases, 12 (5.6%) had subcutaneous fluid, 16 (7.4%) had skin flap margin necrosis. Upper limb lymphatic edema was found in 8 (3.7%) patients, and pectoral muscle contracture with dyspraxia of upper arm occurred in 11 (5.1%) cases. Three year survival rate was 82.3% and five year survival rate was 63.4%. For stage I patients, the five year survival rate attained to 79.6%, and stage II 56.3%.

Conclusions: Preservation of lateral branch of pectoral nerve can avoid complication of pectoral muscle contracture with dyspraxia of upper arm. Early chemotherapy of postoperation prevents breast cancer occurrence and metastasis. Comprehensive treat approaches for operative wound avert subcutaneous fluid, and complex therapy improves long-term effect of breast cancer patients.
