Clinical Scorecard: Oncoplastic Level II Volume Displacement Surgery for Breast Cancer: Aesthetic and Oncological Results
At a Glance
Category
Detail
Condition
Breast cancer treated with breast conserving surgery
Key Mechanisms
Level II oncoplastic breast conserving surgery (OBCS) involving wide local excision and volume displacement reconstruction with immediate contralateral symmetrisation
Target Population
Patients with breast cancer requiring excision of 20–50% of breast volume
Care Setting
Surgical oncology and breast surgery units with multidisciplinary breast disease management teams
Key Highlights
OBCS aims to improve aesthetic outcomes and reduce positive margin rates compared to standard breast conserving surgery.
Intraoperative margin evaluation and placement of clips at tumor bed are standard to ensure oncologic safety.
Five-year overall survival and disease-free survival rates were 97% and 94%, respectively, with a local recurrence rate of 6.4%.
Guideline-Based Recommendations
Diagnosis
Preoperative tumor assessment including location, size to breast volume ratio, and patient anatomy to guide oncoplastic technique choice.
Intraoperative margin evaluation with 'no ink on tumor' rule for invasive cancer and 2 mm margin for DCIS.
Management
Level II OBCS selected for excision of 20–50% breast volume with immediate volume displacement reconstruction and contralateral symmetrisation.
Adjuvant and neoadjuvant treatments according to evidence-based guidelines and multidisciplinary team discussion.
Placement of clips at cardinal points of tumor bed before gland remodeling.
Monitoring & Follow-up
Annual clinical examination, laboratory tests, and imaging for follow-up.
Assessment of local recurrence defined as histologically proven tumor in same breast or skin envelope.
Risks
Postoperative complications occurred in 17% of patients but were managed conservatively.
Margin involvement occurred in 2.7% of cases, with some requiring mastectomy.
Patient & Prescribing Data
109 patients undergoing Level II OBCS with mean age 57.8 years; 24% smokers.
Mean operative time 212 minutes; 72.5% underwent sentinel lymph node biopsy; 33% had nipple-areolar complex grafting; mean resected volume 324 g; mean hospitalization 3.7 days.
Clinical Best Practices
Preoperative planning with detailed drawings to guide oncologic resection and preserve skin/glandular tissue.
Use of validated BREAST-Q questionnaire to assess patient satisfaction at least one year post-surgery.
Multidisciplinary team approach for treatment planning and follow-up.
