BackgroundGiven 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.
MethodsA 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).
ResultsPrimary 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).
ConclusionsNAC for primary AS was well tolerated. Although there was no statistically significant survival benefit, NAC helped define who would benefit from surgical resection. J. Surg. Oncol. 2015 111:829-833.
