Summary
Brief summary (as posted)
Breast cancer is the most common malignancy in women, with stage IV disease at diagnosis in 5-10% of cases. Oligometastatic breast cancer (OMBC), defined as limited metastases (≤3-5 in ≤1-2 organs), may have better outcomes. Systemic therapy is the cornerstone of treatment, while the role of surgery or radiotherapy for the primary tumour remains controversial. Current European Society for Medical Oncology(ESMO )and National Comprehensive Cancer Network(NCCN) guidelines advise systemic therapy as standard, reserving surgery mainly for palliation of local disease. Few Retrospective studies offering primary tumour surgery to oligometastatic breast cancer responding to systemic therapy suggest survival benefit, but several randomised trials to date showed inconsistent results. In Pakistan, data regarding survival pattern after breast surgery in oligometastatic breast cancer are scanty and this study would bridge this knowledge gap.
