Background: The role of brain metastases (BM) surgery is of paramount importance for patients’ progression-free and overall survival. “En-bloc” and “piecemeal” resection represent the main surgical techniques. Although en-bloc resection remains the best surgical option, it is not widely adopted or feasible as the first choice. We describe our point of view about the en-bloc surgical technique with an illustrative case and discuss its indications with pros and cons through a comprehensive literature review. Materials and methods: A Medline search up to December 2023 in the Embase and PubMed online electronic databases was made and PRISMA statement was followed. An illustrative case of “en-bloc” resection from our surgical series was also added as a technical note. Results: We describe tips and tricks of our surgical technique and added a surgical video from our series. The literature review disclosed 19 studies. Resulting data suggested that “en-bloc” resection, when feasible, provides lesser risk of leptomeningeal dissemination, local recurrence rates, intraoperative bleeding occurrence and perioperative complications; in addition, it preserves the normal anatomy. Conclusions: En-bloc resection is the gold standard technique for surgical treatment of brain metastases especially for patients with superficial lesions that are small in size and far from eloquent areas.

Abstract

Background: The role of brain metastases (BM) surgery is of paramount importance for patients’ progression-free and overall survival. “En-bloc” and “piecemeal” resection represent the main surgical techniques. Although en-bloc resection remains the best surgical option, it is not widely adopted or feasible as the first choice. We describe our point of view about the en-bloc surgical technique with an illustrative case and discuss its indications with pros and cons through a comprehensive literature review. Materials and methods: A Medline search up to December 2023 in the Embase and PubMed online electronic databases was made and PRISMA statement was followed. An illustrative case of “en-bloc” resection from our surgical series was also added as a technical note. Results: We describe tips and tricks of our surgical technique and added a surgical video from our series. The literature review disclosed 19 studies. Resulting data suggested that “en-bloc” resection, when feasible, provides lesser risk of leptomeningeal dissemination, local recurrence rates, intraoperative bleeding occurrence and perioperative complications; in addition, it preserves the normal anatomy. Conclusions: En-bloc resection is the gold standard technique for surgical treatment of brain metastases especially for patients with superficial lesions that are small in size and far from eloquent areas.
