title: Applicability of Oncoplastic Breast Conserving Surgery in Asian Breast Cancer Patients.
abstract: BACKGROUND
  There are limited studies on oncoplastic breast conserving surgery in Asian women. We aimed to determine the applicability and safety of oncoplastic surgery, highlighting the specific circumstances when it will be most useful and compare our preferred technique with the worldwide practice of oncoplastic approaches.
  
  
  METHODS
  Breast cancer patients who underwent oncoplastic breast conserving surgery at a single institution from 1st May 201431st March 2015 were included. Data on patient demographics, tumor characteristics and the type of oncoplastic surgery performed were collected.
  
  
  RESULTS
  Nineteen breast cancer patients were identified. 42.1% of patients had grade I ptosis. The indications for surgery included a large tumor to breast size ratio (52.6%), multifocal/multicentric lesions (36.8%) and asymmetric breasts (10.6%), averting a mastectomy in 89.4%. Round block was the commonest technique in 63% of patients, in contrast to the inverted T pattern most frequently used in renowned institutions in the West. Mean and median tumor size and weight of specimen were 29.4/25mm (11 75mm) and 77g/64g (10 246g) respectively. Reexcision rate was 10.5%. Complete mastectomy was performed for one patient. One patient developed wound dehiscence which was treated conservatively. Cosmetic outcome was rated as excellent/good by 94.7% of patients. The patients remained clinically well after a median 16 months follow up.
  
  
  CONCLUSIONS
  Oncoplastic breast conserving surgery is useful in a specific subgroup of Asian patients with a relatively small breast volume and minimal ptosis. Round block was the commonest technique in our series, in contrast to the worldwide utility of oncoplastic techniques. It is oncologically safe and has good cosmetic outcomes.
