ONCOPLASTIC BREAST SURGERY
Breast cancer basics
-
Demographics
-
The most common cancer in females in the UK
-
Around 55,200 new breast cancer cases in the UK are diagnosed every year
-
Incidence in increasing
-
Male breast cancer represents 1% of all breast cancers
-
-
Histopathologic markers​
-
Oestrogen receptor (ER)​
-
Progesterone receptor (PR)
-
HER2/neu oncoprotein
-
-
Risk factors​
-
Early age of menarche​
-
Late menopause
-
First full-term pregnancy after age of 30 years
-
History of premenopausal breast cancer in 2 or more 1st-degree relatives
-
Personal history of breast cancer
-
BRCA1 and BRCA2 mutations (represent about 5% of breast cancers)
-
Carriers have about 60-80% lifetime risk​
-
-
-
Diagnosis​​
-
Triple assessment​
-
History and examination​
-
Imaging (mammography, ultrasound or MRI)
-
Histopathology (core biopsy or fine needle aspiration cytology)
-
-
History of oncoplastic surgery
-
Breast conserving therapy - Combination of breast conserving surgery and radiotherapy
-
In early-stage breast cancer, it has been shown to have comparable overal or distant disease-free survival survival to mastecomy in prospective trials​
-
-
"Oncoplastic surgery" term introduced​ in 1993 by Audretch et al
-
These technique draw from a number of principles inherent to plastic surgery procedures on the breast such as breast reduction or mastopexy
-
Balancing the resection with breast landmarks and shape to preserve breast aesthetics are the fundamentals
-
The most common cause of an unfavourable result is removal of a large amount of breast parenchyma in a small volume breast or excision in an unfavourable location
Patient selection
-
Partial breast reconstruction indicated in patients in whom a standard lumpectomy would lead to gross asymmetry or breast deformity
-
Concerns regarding oncological margin control during resective surgery may affect type of resective surgery and reconstruction choices
-
Timings can be divided into immediate, delayed-immediate and delayed
-
Immediate has risks of positive margins​
-
Delayed has risks of operating in surgically scarred tissue and wound healing problems secondary to radiotherapy
-
Surgical management
-
Volume displacement techniques
-
Parenchymal remodeling​
-
Advancement, rotation or transposition of a large area of breast to fill a small or moderate-sized defect​
-
-
Volume reduction
-
Therapeutic mammoplasty
-
-
Volume replacement techniques
-
Involves adjacent or distan tissue transfer​
-
Volume preserving
-
Implant augmentation
-
Local or perforator flaps
-
Regional or distant flaps
