RESUMEN
Currently, there are no comprehensive breast sarcoma guidelines in the UK. There is therefore a need for guidelines to clarify surgical management, which we have based on data from our regional audit, current evidence, and consensus between West of Scotland Breast Cancer and Scottish Sarcoma Managed Clinical Networks. Methods and results: From 2007 to 2019, 46 patients were treated with breast sarcoma in the West of Scotland. Sarcoma Centre versus Peripheral Hospitals: Incomplete excision rate was 0% at sarcoma centre and 50% at peripheral hospitals (pâ¯=â¯0.0002, Odds Ratio 43). For angiosarcoma, 0% positive margin at the sarcoma centre versus 62.5% at the peripheral unit (pâ¯=â¯0.0036, odds ratio 39.3). Tumours treated at the sarcoma centre were larger than those treated at peripheral hospitals (92.5 versus 39.7â¯mm, pâ¯=â¯0.0009). WLE (wide local excision) versus mastectomy: Out of eight WLE patients, seven (87.5%) had positive margins, with 6 of these patients proceeding to mastectomy (i.e. 75% WLE patients ultimately had a mastectomy). The positive margin rate was significantly higher in WLE (87.5%) than in mastectomy (10.3%) (pâ¯=â¯0.0001, odds ratio 60.7). Survival: No difference was noted between the sarcoma centre and peripheral hospitals for overall survival (pâ¯=â¯0.43), stratified for tumours <5â¯cm (pâ¯=â¯0.16), and disease-free survival (pâ¯=â¯0.45). Conclusions: Our data strongly suggest that specific guidelines are needed for breast sarcoma, and that managing these patients according to breast carcinoma protocols in peripheral hospitals is sub-optimal. We recommend centralisation of breast sarcoma patient care to a specialist sarcoma centre, with WLE not recommended as a firstline surgical option given both the high rates of incomplete excision and subsequent need for completion mastectomy.

BACKGROUND: Though meningiomas are often benign and well circumscribed in nature, many are associated with recurrences and poor outcome because of their attachment to neurovascular nearby structures or invasion of adjacent venous sinuses or bone, forcing incomplete excision and deployment of further salvage therapy. Recently, ALA-FIGS has been reported as an aid to increase the chances of complete resection and minimizing collateral damage. METHODS: Critical review and meta-analyses of the literature published to date. All studies reporting ALA-FIGS in meningiomas were critically reviewed. Nineteen studies fulfilled the inclusion criteria with a total of 222 patients, of which 206 were included in the meta-analyses. RESULTS: ALA-FIGS was highly specific, and highly sensitive (95%, range 91.8-97.7%). There was no correlation between WHO grading (WHO grade I versus WHO grades II & III) and fluorescence (odds ratio 1.2, p>0.05). ALA-FIGS altered the surgical plan intraoperatively in 75% of high-grade and 19% of low-grade meningiomas, improving the extent of surgical excision. ALA-FIGS was also highly sensitive and specific in differentiating hypertrophy and tumor invasion of adjacent dura and bone. CONCLUSIONS: ALA-FIGS in meningiomas is very selective, highly sensitive, and improves the extent of surgical resection in meningiomas. Long-term outcome of these tumors in the future should be categorized into those with and without residual fluorescent tissue. A new surgical resection grading system based on ALA-FIGS is proposed.
