BACKGROUND: Data regarding the role of anthracyclines and taxanes as first-line treatments of metastatic angiosarcoma are limited. METHODS: Records of 117 metastatic angiosarcoma patients who were treated with either doxorubicin or weekly paclitaxel were reviewed. RESULTS: Seventy-five patients (64%) were treated with weekly paclitaxel and 42 (36%) with single-agent doxorubicin. Patients in the weekly paclitaxel group were older and more frequently had angiosarcomas arising from the skin. In the doxorubicin group, 34 patients were evaluable for response: 2 (6%) had complete response, 8 (23.5%) had partial response, 10 (29.5%) had stable disease, and 14 (41%) had progressive disease. In the weekly paclitaxel group, 68 patients were evaluable for response: 9 (13%) had complete response, 27 (40%) had partial response, 20 (29.5%) had stable disease, and 12 (17.5%) had progressive disease. Objective responses to weekly paclitaxel were more frequent in cutaneous angiosarcomas, whereas tumor location did not impact response to doxorubicin. Median progression-free survival (PFS) was 4.9 months (95% confidence interval [95% CI], 3.9-6.0 months). Median overall survival (OS) was 8.5 months (95% CI, 6.4-10.7 months). On multivariate analysis, ECOG performance status (PS) was the sole independent factor associated with PFS and OS. CONCLUSIONS: First-line single-agent doxorubicin and weekly paclitaxel seem to have similar efficacy in metastatic angiosarcomas. Cutaneous angiosarcomas respond favorably to weekly paclitaxel. Best supportive care should be considered in patients with poor PS.

BACKGROUND: In the current study, the authors examined the outcomes of patients with desmoid tumors who received systemic therapy at a single institution to provide a basis for the examination of newer agents. METHODS: Records of patients with desmoid tumors who were treated with chemotherapy at the study institution were reviewed. The activity of nonsteroidal anti-inflammatory drugs was not addressed. Patients without measurable disease and those receiving therapy could not be documented, and those receiving prophylactic therapy were excluded. RESULTS: A total of 68 patients received 157 lines of therapy. At the time of last follow-up, 9 patients had died, 7 of progressive disease. The cohort was 62% female, with a median age of 32.5 years. Approximately 32% of the patients had Gardner syndrome. The median follow-up was 63 months, and patients received a median of 2 lines of therapy. An intra-abdominal primary tumor location was the most common (44%). The greatest Response Evaluation Criteria in Solid Tumors (RECIST) response rate was observed with anthracyclines and hormonal therapy and the lowest response was noted with single-agent dacarbazine/temozolomide or tyrosine kinase inhibitors, principally imatinib. On multivariate analysis, macroscopic nodular morphology and the presence of Gardner syndrome were the only tumor factors found to be associated with a greater time to disease progression. CONCLUSIONS: Compared with other agents, antiestrogens and anthracycline-containing regimens appear to be associated with a higher radiological response rate against desmoid tumors. Systemic therapy can be successful in patients with desmoid tumors, and is a viable option in lieu of morbid or disabling surgery.

Extraskeletal myxoid chondrosarcoma (EMC) is a genetically distinct sarcoma with a propensity for local recurrence and metastasis despite an indolent course. To the authors' knowledge, there are limited data examining chemotherapy outcomes as a guide to therapeutic decisions for unresectable disease.The clinical behavior and treatment responses of 87 patients with EMC who were seen at 2 institutions between 1975 and 2008 were examined.The median age of the patients at the time of diagnosis was 49.5 years, with a male-to-female ratio of 2:1. For patients presenting without metastases, 37% developed local recurrence (median time of 3.3 years) and 26% developed distal recurrence (median time of 3.2 years). Approximately 13% of patients presented with metastases. The 5-year, 10-year, and 15-year overall survival rates were 82%, 65%, and 58%, respectively. Twenty-one patients received 32 evaluable courses of chemotherapy. No significant radiologic or clinical responses were noted. The median time to disease progression while receiving chemotherapy was 5.2 months. The best physician-assessed response to chemotherapy was stable disease for at least 6 months in 25% of patients, stable disease for6 months in 41% of patients, and disease progression in 34% of patients. The estimated progression-free survival rates at 3 months, 4 months, 6 months, and 9 months were 69%, 65%, 40%, and 26%, respectively.This retrospective review highlights the poor response rate to chemotherapy and emphasizes aggressive control of localized disease as the primary approach to management. Although there are biases inherent in retrospective analyses, these data provide a benchmark for time to disease progression for the study of new agents for the treatment of patients with this diagnosis.

BACKGROUND. TZT-1027, a novel chemotherapeutic agent, is derived from dolastatin 10, and blocks cells during G2/M-phase by interfering with microtubule assembly and stability. TZT-1027 has exhibited potential cytotoxic activity in several human cancer cell lines (in vitro) and also demonstrated antitumor activity in human xenografts (in vivo). In addition, Phase I clinical investigations suggested activity in STS (soft-tissue sarcoma). METHODS. Eligible patients were those who had histologic evidence of locally advanced or metastatic STS and who had received 1 prior treatment regimen with an anthracycline-based chemotherapy for metastatic disease. Subjects received intravenous infusions of TZT-1027 over 1 hour on Day 1 and Day 8 of each 21-day treatment course. Efficacy was evaluated per Response Evaluation Criteria in Solid Tumors (RECIST) criteria. RESULTS. Twenty-nine patients were enrolled and 28 patients received at least 1 course of study drug and were eligible for efficacy and safety evaluation. The median age of the patients was 48 years (range, 23–73 years) and the median baseline Eastern Cooperative Oncology Group (ECOG) performance status was 1 (range, 0–2). A total of 67 courses (range, 1–9 courses; median, 2 courses) of TZT-1027 were administered. No patient in the study demonstrated an objective response to treatment. Of 6 patients (21.4%) who experienced disease stabilization, 1 continued to have stable disease for 9.3 months. The median time to tumor progression was 44 days (95% confidence interval [95% CI], 43.0–54.0) and the median survival was 178 days (95% CI, 134.0–317.0). The most commonly reported toxicities were neutropenia, fatigue, and constipation. CONCLUSIONS. TZT-1027 was found to be safe and well tolerated, and the hematologic toxicities observed were consistent with preclinical toxicology and Phase I study findings. No confirmed responses were seen in the current study. Cancer 2006. © 2006 American Cancer Society.

BACKGROUND The objective of this study was to assess the efficacy and toxicity of the imidazotetrazine derivative temozolomide for patients with unresectable or metastatic soft tissue sarcoma. METHODS Twenty-five of 26 patients were eligible and assessable for toxicity and response. Temozolomide was administered twice daily on a 12-hour schedule for 5 days as an oral bolus dose of 200 mg/m2 followed by 9 doses of 90 mg/m2 every 4 weeks. RESULTS There were 2 partial responses, 2 mixed responses, and 3 patients with stable disease that lasted > 6 months, for an overall objective response rate of 8%. At a median follow-up of 13.2 months, the median progression-free survival and the median overall survival were 2.0 months (95% confidence interval [95% CI], 1.7–2.3) and 13.2 months (95% CI, 4.7–31.1), respectively. All responding patients had leiomyosarcoma of uterine or nonuterine origin; and, in a subset analysis of these patients, the objective response rate was 18% (2 of 11 patients), with disease stabilization occurring in 3 of 11 patients (27%). For this subgroup, at a median follow-up of 24.4 months, the median progression-free survival and the median overall survival were 3.9 months (95% CI, 1.9–21.9) and 30.8 months (lower-bound 95% CI, 7.8), respectively. There were no treatment-related deaths or National Cancer Institute Grade 4 toxicities. Grade 3 toxicities included nausea, anemia, fatigue, elevated alkaline phosphatase levels and nonneutropenic fever (1 patient each). CONCLUSIONS Temozolomide at the dose schedule employed in the current study was tolerated well and had modest activity against previously treated unresectable or metastatic leiomyosarcoma of both uterine and nonuterine origin.
