Abstract:
Objective To analyze the survival and prognostic factors in the treatment of angiosarcoma. Methods A retrospective study was performed on clinical data of 30 patients pathologically diagnosed with angiosarcoma who were admitted to our hospital from 1988 to 2015 and had complete follow?up data. In those patients, 18 patients received comprehensive treatment, containing 9 patients treated with surgery plus radiotherapy, 4 patients with surgery plus chemoradiotherapy, and 5 with surgery plus chemotherapy;12 patients received non?comprehensive treatment, containing 11 patients treated with surgery alone and 1 patient radiotherapy alone. The survival rates were calculated using the Kaplan?Meier method and analyzed using the log?rank test. The Cox regression model was used for multivariate prognostic analyses. Results The 1?, 2?, and 5?year sample sizes were 29,26, and 18, respectively. The 1?, 2?, and 5?year overall survival ( OS) rates were 70?1%, 49?1%, and 40?9%, respectively;the 1?, 2?, and 5?year local relapse?free survival rates were 52?8%, 44?0%, and 35?2%, respectively;the 1?, 2?, and 5?year distant metastasis?free survival rates were 81?6%, 68?0%, and 56?7%, respectively. The multivariate analysis showed that tumor site, tumor size, staging, and visible tumor residue after initial treatment were prognostic factors for OS ( P= 0?027, 0?027, 0?011, 0?000 );In the patients with stage Ⅰ or Ⅱ disease, the comprehensive treatment achieved a significantly lower local?relapse rate than the individual treatment ( P=0?006);gender, age, staging, and tumor site were prognostic factors for distant metastasis ( P=0?028, 0?011, 0?015, 0?022 ) . Conclusions Early diagnosis and early treatment are recommended for angiosarcoma, which has high local recurrence and distant metastasis rates. Comprehensive treatment ( surgery plus radiotherapy and/or chemotherapy) is recommended for patients with stage Ⅰ or Ⅱ disease. Tumor site, tumor size, staging, and visible tumor residue after initial treatment are prognostic factors.
