BACKGROUND: Prognostic factors for patients with soft‐tissue sarcoma who are treated with conservative surgery and radiation are documented poorly.METHODS: The clinicopathologic features and disease outcome for 1225 patients with localized sarcoma who were treated with conservative surgery and radiation were reviewed retrospectively. Actuarial univariate and multivariate statistical methods were used to determine significant prognostic factors for local control, metastatic recurrence, and disease specific survival.RESULTS: The median follow‐up of surviving patients was 9.5 years. The respective local control rates at 5 years, 10 years, and 15 years were 83%, 80%, and 79%. Factors predictive of local recurrence were positive or uncertain resection margins; tumors located in the head and neck and the deep trunk; presentation with local recurrence; patient age > 64 years; malignant fibrous histiocytoma, neurogenic sarcoma. or epithelioid sarcoma histopathology; tumor measuring > 10 cm in greatest dimension; and high pathologic grade. Freedom from metastasis at 5 years, 10 years, and 15 years was 71%, 68%, and 66%, respectively. Factors that were predictive of metastatic recurrence were high tumor grade; large tumor size (> 5 cm); and leiomyosarcoma, rhabdomyosarcoma, synovial sarcoma, or epithelioid sarcoma. The respective disease specific survival rates at 5 years, 10 years, and 15 years were 73%, 68%, and 65%. Adverse factors for disease specific survival were high tumor grade; large tumor size (> 5 cm); tumors located in the head and neck and deep trunk; rhabdomyosarcoma, epithelioid sarcoma, or clear cell sarcoma; patient age > 64 years; and positive or uncertain resection margins.CONCLUSIONS: Soft‐tissue sarcoma comprises a heterogeneous group of diseases. Prognostic factors for local recurrence, metastatic recurrence, lymph node recurrence, disease free survival, and disease specific survival are different, and optimal treatment strategies need to take this complexity into account.

PURPOSE: To evaluate the therapeutic value of resection and the potential benefits of and indications for adjuvant and definitive radiation therapy for desmoid tumors. MATERIALS AND METHODS: We performed a retrospective review of 189 consecutive cases of desmoid tumor treated with surgical resection, resection and radiation therapy, or radiation therapy alone. Treatment was surgery alone in 122 cases, surgery and radiation therapy in 46, and radiation therapy alone in 21. Median follow-up was 9.4 years. RESULTS: Overall, 5- and 10-year actuarial relapse rates were 30% and 33%, respectively. Uncorrected survival rates were 96%, 92%, and 87% at 5, 10, and 15 years, respectively. For the patients treated with surgery, the actuarial relapse rates were 34% and 38% at 5 and 10 years, respectively. Among 78 patients with negative margins, the 10-year recurrence rate was 27%, whereas 40 margin-positive patients had a 10-year relapse rate of 54% (P = .003). Tumors located in an extremity also had a poorer prognosis than did those in the trunk. For patients treated with radiation therapy for gross disease, the 10-year actuarial relapse rate was 24%. For patients treated with combined resection and radiation therapy, the 10-year actuarial relapse rate was 25%. The addition of radiation therapy offset the adverse impact of positive margins seen in the surgical group. CONCLUSION: Wide local excision with negative pathologic margins is the treatment of choice for most desmoid tumors. Function-sparing resection is appropriate because adjuvant radiation therapy can offset the adverse impact of positive margins. Unresectable disease should be treated with definitive radiation therapy.

Purpose: To determine the incidence of potentially treatment-related mortality in long-term survivors of testicular seminoma treated by orchiectomy and radiation therapy (XRT). Patients and Methods: From all 477 men with stage I or II testicular seminoma treated at The University of Texas M.D. Anderson Cancer Center (Houston, TX) with postorchiectomy megavoltage XRT between 1951 and 1999, 453 never sustained relapse of their disease. Long-term survival for these 453 men was evaluated with the person-years method to determine the standardized mortality ratio (SMR). SMRs were calculated for all causes of death, cardiac deaths, and cancer deaths using standard US data for males. Results: After a median follow-up of 13.3 years, the 10-, 20-, 30-, and 40-year actuarial survival rates were 93%, 79%, 59%, and 26%, respectively. The all-cause SMR over the entire observation interval was 1.59 (99% CI, 1.21 to 2.04). The SMR was not excessive for the first 15 years of follow-up: SMR, 1.30 (95% CI, 0.93 to 1.77); but beyond 15 years the SMR was 1.85 (99% CI, 1.30 to 2.55). The overall cardiac-specific SMR was 1.61 (95% CI, 1.21 to 2.24). The cardiac SMR was significantly elevated only beyond 15 years (P < .01). The overall cancer-specific SMR was 1.91 (99% CI, 1.14 to 2.98). The cancer SMR was also significant only after 15 years of follow-up (P < .01). An increased mortality was evident in patients treated with and without mediastinal XRT. Conclusion: Long-term survivors of seminoma treated with postorchiectomy XRT are at significant excess risk of death as a result of cardiac disease or second cancer. Management strategies that minimize these risks but maintain the excellent hitherto observed cure rates need to be actively pursued.

Purpose: This study compared a large series of desmoid patients treated at a single institution to a previously published series from the same institution to determine if patient population characteristics, treatment approaches, and clinical outcomes had undergone change over the two study periods. Materials and Methods: Data from a prospective soft tissue tumor database was used to analyze clinical courses of 189 desmoid patients treated at The University of Texas M.D. Anderson Cancer Center (UTMDACC) from 1995 to 2005 as compared with 189 UTMDACC desmoid patients treated between 1965 and 1994. Results: A nearly three-fold increase in annualized UTMDACC desmoid referral volume with significantly higher percentages and numbers of primary desmoid tumor referrals to UTMDACC was observed in the most recent study period. Significantly increased systemic therapy use and decreased reliance on surgery alone was observed more recently. While the recent series patients had higher rates of macroscopic residual disease and equivalent rates of positive microscopic margins after definitive surgery, the estimated 5-year local recurrence rate of 20% was improved compared with the 30% rate observed in the earlier series. Conclusion: Increased awareness of the complex multidisciplinary management needed for desmoid tumor control may underlie significantly increased numbers of referrals to UTMDACC, especially primary untreated desmoids. Increased neoadjuvant treatments may be associated with improved desmoid patient outcomes. These trends should be supported, particularly if personalized molecular-based therapies are to be rapidly and effectively deployed for the benefit of those afflicted by this rare and potentially debilitating disease.

BACKGROUND: Angiosarcoma of the breast is a rare entity. The objectives of this study were to evaluate prognostic factors and determine outcomes in a large contemporary series of patients.METHODS: Clinical and pathologic factors were analyzed in all patients with angiosarcoma of the breast treated between 1990 and 2003. Overall survival (OS) and disease‐free survival (DFS) were estimated using the methods of Kaplan and Meier. Multivariate analyses were performed to evaluate prognostic factors.RESULTS: Fifty‐five women with angiosarcoma of the breast were identified. The median age was 49.1 years, and the median follow‐up time was 3.7 years. The median OS and DFS were 2.96 years and 2.26 years, respectively. For the 32 patients with primary angiosarcoma of the breast 5‐year OS was 59%. Twenty‐three (42%) patients had received prior radiation therapy for the treatment of breast cancer. These patients with radiation therapy‐associated angiosarcoma were on average 30 years older and less likely to present with distant metastatic disease than patients presenting with radiation‐naive angiosarcoma of the breast. Although radiation‐naive patients appeared to have had better early DFS and OS, the Kaplan–Meier curves were not statistically different between patients with radiation therapy‐associated disease and radiation therapy‐naive patients. On multivariate analysis, tumor recurrence (P = 0.006) was the only significant adverse prognostic factor noted for OS.CONCLUSIONS: In this series of 55 patients with angiosarcoma of the breast, radiation therapy‐naive angiosarcomas occurred in younger patients, but they behaved similarly to radiation therapy‐associated angiosarcomas.
