Abstract

BACKGROUND: Given the propensity for hematogenous metastases, neoadjuvant chemotherapy (NAC) could treat occult metastatic disease early, potentially improving survival and better defining which primary angiosarcomas (AS) benefit from surgical resection.

METHODS: A retrospective comparison was performed of 23 patients with resectable, localized cutaneous/soft tissue primary AS treated with surgery alone (S, n = 13) or NAC followed by surgery (NAC-S, n = 12).

RESULTS: Primary sites included breast/chest (n = 9), head/neck (n = 9), extremity (n = 3), and other (n = 2). 23% S versus 40% NAC-S had prior radiation (RT). NAC regimens were paclitaxel (n = 6) or gemcitabine/docetaxel (n = 4). Seventy percent were high grade. Distant metastases were found in 17% after NAC. Non-primary wound closure was required in 54 %S versus 30%NAC-S (P = 0.4). R0 resections were achieved in 85% S versus 80% NAC-S (30% had a complete pathologic response). Two-year local recurrence (LR)-free, disease-free, and overall survivals were 67.1, 38.5, and 61.5% for S versus 68.6, 54.9, and 68.6% for NAC-S (P = 0.52, 0.67, and 0.58). The mean number of surgical resections/patient to maintain local control was 1.8 S versus 1.3 NAC-S (P = 0.06).

CONCLUSIONS: NAC for primary AS was well tolerated. Although there was no statistically significant survival benefit, NAC helped define who would benefit from surgical resection.
