Shaving as an Safe Alternative to Frozen Section Analysis

Breast cancer remains the most common malignancy among women worldwide and represents a major health burden. Breast-conserving surgery (BCS) has become the standard of care for early-stage breast cancer, aiming to achieve complete tumor excision with histologically clear margins combined with adjuvant radiotherapy, offers equivalent survival rates to mastectomy in early-stage cases. . Positive surgical margins are strongly associated with increased rates of local recurrence and frequently necessitate re-excision. Traditionally, intraoperative frozen section analysis (FSA) has been used to assess margin status. However, this technique has several drawbacks, including: * Limited availability in many centers. * Requires high-experienced cytopathologists making it challenging in resource-limited places. * Adds substantial cost. * Time consuming (prolonged operative time). * Recently, the tumor bed cavity shaving (TBCS) has been introduced as a more practical alternative technique that can reduce the incidence of positive margins without relying on intraoperative pathology. tumor bed cavity shaving (TBCS) means additional thin layers of tissue approximately 5:10 mm in thickness are removed circumferentially from the cavity walls . With many advantages: * feasible in centers lacking intraoperative pathological facilities. * Time saving (significantly reduces the overall operative time). * cost-effectiveness. * Technically simple (Easy to perform without the need for specialized equipment or advanced facilities). * it represents a suitable option in low- to medium-socioeconomic settings, where resources and advanced intraoperative support may be limited. * It is expected to demonstrate comparable oncological safety to Intraoperative Frozen Section Analysis (FSA) in achieving margin negativity with Significant reduction anticipated in Positive margin rates\&Re-excision frequency\&Operative duration and Overall procedural cost.
