Wide surgical excision is the backbone of therapy for localized soft tissue sarcoma and often produces excellent results. Patients with a marginal resection of disease and high-grade or large tumors are at an increased risk of recurrence. Radiation therapy (external beam or brachytherapy) has been shown to reduce the risk of local recurrence of disease and should be offered to patients with large (>5 cm) or high-grade sarcomas, especially if a wide resection cannot be performed. Use of preoperative versus postoperative radiation therapy should be planned, in consultation with a radiation oncologist and a surgical oncologist, before resection of the sarcoma if possible. Chemotherapy using an anthracycline- and ifosfamide-based regimen may improve disease-free and overall survival rates. Chemotherapy appears to be most beneficial for patients with very large (≥10 cm), high-grade sarcomas of the extremity who are at a high risk of experiencing distant recurrence of disease. The effect of adjuvant chemotherapy on overall survival remains controversial. Research is greatly needed to identify the patients who are most likely to benefit from conventional chemotherapy, improve the treatment of retroperitoneal sarcomas, and identify novel agents that may impact the natural history of high-risk soft tissue sarcoma.

e21503 Background: Neo-adjuvant therapy of soft tissue sarcoma is not standardized. Anthracyclines (A) improve disease free and overall survival in high grade extremity soft tissue sarcomas measuring more than 5 cm. A and ifosfamide (I) therapy require inpatient administration and is associated with significant toxicities when administered in combination with RT. G in combination with D has been shown to prolong progression free and overall survival in patients with advanced or metastatic STS after progression on A and I, and in patients unable to receive the combination. The safety of administration of G with radiation is not known. We evaluated the safety of neo-adjuvant G and D in combination with RT in patients with STS. Methods: Retrospective analysis of subjects with high grade STS treated with RT and neo-adjuvant chemotherapy with G and D was conducted. G 600mg/m2 was administered on days 1 and 8 along with D 75 mg/m2 on day 8 for a total of 3 cycles. 2200 cGY RT was administered in 11 daily fractions between cycles 1 and 2 and between cycles 2 and 3. 72 hour gap was given between RT and chemotherapy. Chemotherapy was administered on outpatient basis. Efficacy was evaluated by the extent of tumor necrosis at the time of surgery. Safety was evaluated by the presence of complications following chemotherapy. Results: GD + R was administered to 12 patients in the neo-adjuvant setting. 11 of them were evaluable for response. 10 of the 11 patients had evidence of tumor necrosis at the time of surgery. 1 patient had poor response. 3 of 11 patients had neutropenia complicating neo-adjuvant chemotherapy. 4 patients required hospital admission post chemotherapy. 3 for neutopenic fever, and 1 for fever, chills and pneumonia without neutropenia. Conclusions: Gemcitabine and taxotere combination with radiation therapy can be administered safely on outpatient basis with minimal toxicity. Further safety and efficacy evaluation of this therapy will need to be confirmed in a prospective phase II study. No significant financial relationships to disclose.

Soft tissue sarcomas are a heterogeneous group of neoplasms that arise throughout the body, but most commonly in the extremity and trunk. A multidisciplinary treatment approach has resulted in local control rates exceeding 90% and 5-year survival rates exceeding 70%. For patients with localized soft tissue sarcoma, limb-sparing surgical resection is the mainstay of therapy, with radiation therapy and chemotherapy used as adjuncts to reduce local and distant recurrences. Amputation is reserved for patients with primary or recurrent tumors that cannot be grossly resected with a limb-sparing procedure and preservation of function, which should occur in less than 5% of patients. Most patients who die of soft tissue sarcoma die of metastatic disease, which becomes evident within 2 to 3 years of initial diagnosis in 80% of cases, highlighting the need for improved systemic therapy options and optimal treatment at the time of diagnosis. This review contains 13 figures, 4 tables and 53 references Key words: amputation, multimodality, radiation therapy, soft tissue sarcoma, staging, surgery, treatment, wide resection

11054 Background: Large, high-grade extremity/trunk (ET) non-rhabdomyosarcoma soft-tissue sarcoma (STS) is at high risk for distant recurrence and death. The integration of chemotherapy (C) to standard of care neoadjuvant radiotherapy (RT) remains controversial, even for these patients. This study examines the impact of adding C to neoadjuvant RT on overall survival (OS) in high risk ET-STS. Methods: The National Cancer Data Base (NCDB) was queried for patients ≥18 years with high risk (≥5 cm + high grade) non-rhabdomyosarcoma ET-STS (WHO histology) who received neoadjuvant RT and limb sparing surgery from 2006-2014. Patients were next stratified based upon receipt of C (RT and CRT cohorts). Overall survival (OS) for RT vs CRT cohorts was analyzed using the Kaplan-Meier (KM) method, log-rank test, and Cox proportional hazards models. Propensity score-matched analysis (PSM) was employed to account for potential treatment selection bias between cohorts. Results: A total of 848 (71.1%) and 344 (28.9%) patients received RT and CRT, respectively. Patient cohorts were well-balanced except for the CRT cohort having higher rates of treatment in the West (22.1% vs 10.6%) & Midwest (28.3% vs 22.7%), Charlson-Deyo [CD] score 0 vs ≥1 (85.5% vs 79.4%), younger age (≤50) (45.9% vs 21.7%), synovial sarcoma histology (18.9% vs 3.2%), earlier year of diagnosis (2006-2010) (39.5% vs 32.3%), and positive lymphovascular invasion (2.0 vs 1.51%), (p < 0.05 each). The KM 5-year OS was significantly higher in the CRT vs RT cohort: 69.2% vs 58.1% on univariate (p < 0.0001) and multivariate analysis (Hazard Ratio [HR]: 0.66; 95% Confidence Interval [CI]: 0.52-0.85; p = 0.001) even after adjusting for age, race, income, CD score, histology, tumor size, tumor grade, and primary site (lower extremity; upper extremity; trunk). PSM identified evenly matched cohorts of 300 patients each with respect to age, income, CD score, histology, grade, tumor size, and primary site. The addition of neoadjuvant C remained prognostic for OS on PSM (HR: 0.74 [0.56-0.99], p = 0.042). Conclusions: The addition of C to neoadjuvant RT was associated with improved OS in patients with high risk non-rhabdomyosarcoma ET-STS in the NCDB. These hypothesis generating results support prospective evaluation.

Background: Radio-frequency ablation (RFA) and Stereotactic Body Radiation Therapy (SBRT) are two emerging therapies for lung metastases. Introduction: We performed a literature review to evaluate outcomes and complications of these procedures in patients with lung metastases from soft tissue sarcoma (STS). Method: After selection, seven studies were included for each treatment encompassing a total of 424 patients: 218 in the SBRT group and 206 in the RFA group. Results: The mean age ranged from 47.9 to 64 years in the SBRT group and from 48 to 62.7 years in the RFA group. The most common histologic subtype was, in both groups, leiomyosarcoma. : In the SBRT group, median overall survival ranged from 25.2 to 69 months and median disease-free interval from 8.4 to 45 months. Two out of seven studies reported G3 and one G3 toxicity, respectively. In RFA patients, overall survival ranged from 15 to 50 months. The most frequent complication was pneumothorax. : Local control showed high percentage for both procedures. Conclusion: SBRT is recommended in patients unsuitable to surgery, in synchronous bilateral pulmonary metastases, in case of deep lesions and in patients receiving high-risk systemic therapies. RFA is indicated in case of a long disease-free interval, in oligometastatic disease, when only the lung is involved, in small size lesions far from large vessels. : Further large randomized studies are necessary to establish whether these treatments may also represent a reliable alternative to surgery.

We have documented functional and psychosocial changes in patients with extremity soft tissue sarcomas who have undergone multimodality limb-sparing treatments. In 88 patients, parameters related to economic status, sexual activity, pain, limb function, and global quality of life (QOL) were recorded prior to surgery and every 6 months postoperatively. Changes from the preoperative assessment for every parameter were analyzed in each patient. Six months after surgery, there was a decrease in employment status, sexual activity, and in limb function in a significant number of patients. At 12 months, these decreases were still evident. Despite these changes, global QOL measured by a standardized test showed at least some improvement in a significant proportion of patients at 12 months. These findings highlight the difficulty in defining QOL. It could not be ascertained if radiation therapy and/or chemotherapy were causative factors in specific changes because of the small numbers of patients in each subgroup. However, among 60 patients with high-grade sarcomas, significant wound problems developed in 10 of 33 who received postoperative radiation therapy in combination with adjuvant doxorubicin and cyclophosphamide chemotherapy compared with one of 27 patients who received adjuvant chemotherapy alone (P = .016). Also, among high-grade sarcoma patients with 12-month follow-up, six of 19 patients who received radiation therapy and chemotherapy developed joint contractures compared with zero of 15 patients who received chemotherapy alone (P less than .04). The combination of postoperative radiation therapy and chemotherapy appeared to be associated with significantly more tissue-related injury in patients with high-grade sarcomas compared with chemotherapy alone.

PURPOSE: To determine whether treatment-induced pathologic necrosis correlates with local recurrence and overall survival in patients who receive neoadjuvant therapy for high-grade extremity soft tissue sarcomas. PATIENTS AND METHODS: Four hundred ninety-six patients with intermediate- to high-grade extremity soft tissue sarcomas received protocol neoadjuvant therapy. All patients underwent surgical resection after neoadjuvant therapy and had pathologic assessment of tumor necrosis in the resected specimens. RESULTS: The 5- and 10-year local recurrence rates for patients with ≥ 95% pathologic necrosis were significantly lower (6% and 11%, respectively) than the local recurrence rates for patients with less than 95% pathologic necrosis (17% and 23%, respectively). The 5- and 10-year survival rates for the patients with ≥ 95% pathologic necrosis were significantly higher (80% and 71%, respectively) than the survival rates for the patients with less than 95% pathologic necrosis (62% and 55%, respectively). Patients with less than 95% pathologic necrosis were 2.51 times more likely to develop a local recurrence and 1.86 times more likely to die of their disease as compared with patients with ≥ 95% pathologic necrosis. The percentage of patients who achieved ≥ 95% pathologic necrosis increased to 48% with the addition of ifosfamide as compared with 13% of the patients in all the other protocols combined. CONCLUSION: Treatment-induced pathologic necrosis is an independent predictor of both local recurrence and overall survival in patients who receive neoadjuvant therapy for high-grade extremity soft tissue sarcomas. A complete pathologic response (≥ 95% pathologic necrosis) correlated with a significantly lower rate of local recurrence and improved overall survival.
