11555 Background: Soft tissue sarcomas (STS) are rare often malignant tumors. The primary treatment of most STS is radical resection with adjuvant radiotherapy. Our previous study showed that the use of preoperative hypofractionated radiotherapy is safe and efficient in the treatment of unselected group of patients with STS. Aim of this study was to assess the use of the treatment scheme in patients with primary STS treated in one institution. Methods: 311 patients (52% female) with primary locally advanced STS participated in this prospective trial conducted from 2010 till 2017. Median age was 55 years (range: 17-91). Median follow up is 57 months (95%CI 55-61). The most common subtypes were pleomorphic sarcoma, liposarcoma and synovial sarcoma. Median tumor size was 11cm. 258 patients (83%) had high grade tumors. The most common tumor localization were lower limbs (72%). 30% of patients received preoperative chemotherapy. For five consecutive days radiotherapy in 5 x 5Gy fraction was applied, with immediate (2-4 days) resection of the tumor. Results: In 260 patients (83.6%) clear surgical margins (R0) were obtained. 107 patients were dead at the time of the analysis.5-year overall survival is 63%. 156 (50%) had a recurrence of the disease. Local recurrence (LR) was found in 13.8% of the patients. Median time from surgery to LR was 14.7 months. In 56% of patients with LR another limb spearing radical surgery could be performed. Factors that had a significant adverse impact on LR were histological subtype (p = 0.017) and surgical margin status (p = 0.013). Factors that had a significant adverse impact on overall survival were tumor size (p < 0.0001), grade (p = 0.0047) and surgical margin status (p = 0.013). 96 patients (30.8%) had any kind of treatment toxicity, factor having negative impact on the toxicity was lower limb location of the tumor (p = 0.0012). 20 patients (6.4%) required surgery for treatment of the complications. 14.6% patients had prolonged healing of the wound ( > 1 month), 8.3% had wound dehiscence, 1.4% required prolonged punctures of the lymph fluid, 2.3% had severe fibrosis leading to contracture of limb, 11% patients prolonged edema of the operated limb. 0.9% of patients had a fracture of the treated limb. Conclusions: In this group, with a big percentage of patients with large, high grade STS use of hypofractionated preoperative radiotherapy was associated with similar local control when compared to published studies. The early toxicity is tolerable, with a small amount of late complications.

The Impact

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: The use of adjuvant radiotherapy (RT) shows a significantly decreased incidence of local recurrence (LR) in soft tissue sarcomas (STS). This study aimed to assess the treatment scheme’s effect in patients with primary STS treated at one institution. Methods: In this phase 2 trial, 311 patients aged ≥18 years with primary, locally advanced STS of the extremity or trunk wall were assigned to multimodal therapy conducted at one institution. The preoperative RT scheme consisted of 5 Gy per fraction for a total dose of 25 Gy. Surgery was performed within 2–4 days from the last day of RT. The primary endpoint was LR-free survival (LRFS). Adverse events of the treatment were assessed. Results: We included 311 patients with primary locally advanced STS. The median tumor size was 11 cm. In total, 258 patients (83%) had high-grade tumors. In 260 patients (83.6%), clear surgical margins (R0) were obtained. Ninety-six patients (30.8%) had at least one type of treatment adverse event. LR was observed in 13.8% patients. The 5-year overall survival was 63%. Conclusion: In this group, with a significant percentage of patients with extensive, high-grade STS, hypofractionated preoperative RT was associated with good local control and tolerance.

PURPOSE There are sparse data on the outcome of patients with locally advanced breast cancer (LABC). This report is on the prognostic factors and long-term outcome from Cancer Institute, Chennai. METHODS This is an analysis of untreated patients with LABC (stages IIIA-C) who were treated from January 2006 to December 2013. RESULTS Of the 4,577 patients with breast cancer who were treated, 2,137 patients (47%) with LABC were included for analysis. The median follow-up was 75 months (range, 1-170 months), and 2.3% (n = 49) were lost to follow-up at 5 years. The initial treatment was neoadjuvant concurrent chemoradiation (NACR) (77%), neoadjuvant chemotherapy (15%), or others (8%). Patients with triple-negative breast cancer had a pathologic complete response (PCR) of 41%. The 10-year overall survival was for stage IIIA (65.1%), stage IIIB (41.2%), and stage IIIC (26.7%). Recurrence of cancer was observed in 27% of patients (local 13% and distant 87%). Multivariate analysis showed that patients with a tumor size > 10 cm (hazard ratio [HR], 2.19; 95% CI, 1.62 to 2.98; P = .001), hormone receptor negativity (HR, 1.45; 95% CI, 1.22 to 1.72; P = .001), treatment modality (neoadjuvant chemotherapy, HR, 0.56; 95% CI, 0.43 to 0.73; P = .001), lack of PCR (HR, 2.36; 95% CI, 1.85 to 3.02; P = .001), and the presence of lymphovascular invasion (HR, 1.97; 95% CI, 1.60 to 2.44; P = .001) had decreased overall survival. CONCLUSION NACR was feasible in inoperable LABC and gave satisfactory long-term survival. PCR was significantly higher in patients with triple-negative breast cancer. The tumor size > 10 cm was significantly associated with inferior survival. However, this report acknowledges the limitations inherent in experience of management of LABC from a single center.

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.

PURPOSE: The rarity and heterogeneity of pediatric nonrhabdomyosarcoma soft tissue sarcoma (NRSTS) has precluded meaningful analysis of prognostic factors associated with surgically resected disease. To define a population of patients at high risk of treatment failure who might benefit from adjuvant therapies, we evaluated the relationship between various clinicopathologic factors and clinical outcome of children and adolescents with resected NRSTS over a 27-year period at our institution. PATIENTS AND METHODS: We analyzed the records of 121 consecutive patients with NRSTS who underwent surgical resection between August 1969 and December 1996. Demographic data, tumor characteristics, treatment, and outcomes were recorded. Univariate and multivariate analyses of prognostic factors for survival, event-free survival (EFS), and local and distant recurrence were performed. RESULTS: At a median follow-up of 9.2 years, 5-year survival and EFS rates for the entire cohort were 89% ± 3% and 77% ± 4%, respectively. In univariate models, positive surgical margins (P = .004), tumor size ≥ 5 cm (P < .001), invasiveness (P = .002), high grade (P = .028), and intra-abdominal primary tumor site (P = .055) adversely affected EFS. All of these factors except invasiveness remained prognostic of EFS and survival in multivariate models. Positive surgical margins (P = .003), intra-abdominal primary tumor site (P = .028), and the omission of radiation therapy (P = .043) predicted local recurrence, whereas tumor size ≥ 5 cm (P < .001), invasiveness (P < .001), and high grade (P = .004) predicted distant recurrence. CONCLUSION: In this largest single-institution analysis of pediatric patients with surgically resected NRSTS, we identified clinicopathologic features predictive of poor outcome. These variables should be prospectively evaluated as risk-adapted therapies are developed.

Purpose.To make recommendations for the use of doxorubicin-based chemotherapy in patients with soft-tissue sarcoma.Patients.The recommendations apply to patients with symptomatic unresectable locally advanced or metastatic soft-tissue sarcoma who are candidates for palliative chemotherapy.Methods.A systematic review of the published literature was combined with a consensus process around the interpretation of the evidence in the context of conventional practice to develop an evidence-based practice guideline.Results.Eight randomized trials comparing doxorubicin-based combination versus doxorubicin single-agent chemotherapy were reviewed. Response rates and overall survival were evaluated using pooled statistical analysis.The pooled response data in 2281 patients showed a slight trend favouring the combination therapy, although this did not reach statistical significance (odds ratio (OR), 0.79; 95% confidence interval (CI), 0.60–1.05;p=0.10). Survival data could only be abstracted from six studies involving 2097 patients, and showed no significant advantage for combination therapy (OR, 0.84; 95% CI, 0.67–1.06;p=0.13). Data on adverse effects could not be combined in a meta-analysis; however nausea, vomiting and myelosuppression were consistently more severe with combination chemotherapy than with single-agent chemotherapy.Discussion.Single-agent doxorubicin is an appropriate first-line chemotherapy option for advanced or metastatic soft-tissue sarcoma. Some doxorubicin-based combination chemotherapy regimens, given in conventional doses, produce only marginal increases in response rates, at the expense of increased adverse effects, and with no improvements in overall survival. Future randomized clinical trials should compare new regimens, whose activity has been established in single-arm studies, with single-agent doxorubicin, and include quality of life as an outcome measure.

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.

267 Background: Outcomes following surgical management of intrahepatic cholangiocarcionma (ICC) have largely focused on overall survival. Data on recurrence following surgery for ICC are limited. We sought to investigate rates and patterns of recurrence in patients following curative intent surgery for ICC. Methods: 449 patients who underwent surgery for ICC between 1973 and 2010 were identified from an international multi-institutional database. Clinicopathologic data, recurrence patterns, and recurrence-free survival (RFS) were analyzed. Results: Most patients had a solitary tumor (70%) with a median tumor size of 6.5 cm. The majority of lesions did not have vascular invasion (69%). Surgical treatment was < hemi-hepatectomy (47%), hemi-hepatectomy (26%), or extended hepatectomy (27%). On pathology, 23% patients had lymph node metastasis and 18% had a microscopically positive (R1) margin. A subset of patients received adjuvant chemotherapy (32%) or chemoradiation (39%). While 5-year overall survival was 31%, 351 (78%) patients recurred with a median RFS time of 13.2 months. First recurrence site was intra-hepatic only (54%), extra-hepatic only (24%), intra- and extra-hepatic (22%). There was no difference in RFS based on site of recurrence (intra-hepatic: 11.2 months; extra-hepatic 11.6 months; intra- and extra-hepatic: 9.6 months; P=0.16). An R1 surgical margin (HR: 1.56, p=0.02) and neural invasion (HR: 1.55, p=0.02) were associated with overall recurrence, while male gender (HR: 1.70, p=0.011), >50% liver parenchyma resection HR: 1.97, p=0.03), primary tumor size (1.05, p=.02), and poor differentiation (HR: 1.92, p=0.01, were associated with intrahepatic recurrence. Receipt of adjuvant therapy was not associated with risk of recurrence (P>0.05). Conclusions: Over 75% of patients developed recurrence following curative intent surgery for ICC. The pattern of failure was distributed relatively equally with half of patients recurring with liver only disease while half had an extrahepatic metastatic site of recurrence. Future efforts need to be directed toward identifying more effective adjuvant regimens given the high rate of recurrence.
