On representing the prognostic value of continuous gene expression biomarkers with the restricted mean survival curve.

OBJECTIVE

To assess the oncologic and cosmetic outcomes for breast cancer patients who underwent breast conservation therapy using Level II oncoplasty techniques.

METHODS

The prospective, non-randomised and descriptive study was conducted at the Department of Surgery, Unit IV of Civil Hospital, Karachi, from December 2009 to November 2011 in which 21 consecutive women with breast carcinoma who underwent wide local excision with remodeling mammoplasty were enrolled. All patients were reviewed by the surgeon and medical oncologist every 3 months for the first year. A grading system of 5-1 (excellent to poor) was employed and those with 3 or more were considered to have acceptable results.

RESULTS

The mean patient age was 45.38 +/- 10.09 years (range: 26-70); 11 (52.3%) were premenopausal and 10 (47.7%) were postmenopausal; and 5 (27.8%) had family history of breast cancer. The mean size of the tumour determined by histology was 59.9 +/- 3.18 mm (range: 25-150). Eight (30%) patients received preoperative chemotherapy to downsize the tumour. Three (14.2%) patients received preoperative radiotherapy. Mean operative time was 1.59 +/- 0.52 hours (range: 1-2.5 hours). Mean volume of breast tissue excised from the breast containing the tumour was 545.27 +/- 412.06 cm3 (range: 43.70-1456). Assessment of excision margins showed no tumour at the margins of 19 (90.4%) patients. Two (9.5%) patients had close but negative margins. The mean hospital stay was 7.10 +/- 3.30 days (range: 4-15). There were early complications in 4 (19%) patients. One (4.76%) patient had late complications. Two (9.5%) patients developed tumour recurrence; both had an ipsilateral tumour recurrence. None of the patients developed metastases and one died of cardiac problem. Twenty (95.2%) patients had an acceptable post-surgical cosmetic result.

CONCLUSION

Level II oncoplasty was a safe option in breast conservation allowing large-sized and difficult-location tumour excision with good cosmetic outcome in the study group. There is a need to increase the awareness and acceptance of this new technique not only amongst patients but also doctors.
