e18519 Background: Thymomas are epithelial thymic tumors, generally considered to have an indolent growth pattern but are malignant. 20-40% of patients with thymomas have paraneoplastic syndromes,including myasthenia gravis(MG). The objective of this study is to evaluate outcome of surgical treatment to thymoma and determine whether the different pathological and clinical characteristics of thymomas influences the prognosis in thymoma patients. Methods: We retrospectively studied data from 228 consecutive patients operated on from1992 to 2007. All thymic epithelial tumors were reclassified according to the WHO histologic classification, and the Masaoka clinical staging system. Patients with type A and stage I thymoma had no adjuvant therapy. Most patients with types AB and B1 thymomas had radiotherapy postoperatively. Patients (stageII, III) were treated with adjuvant mediastinal radiation therapy, and both adjuvant radiation therapy and chemotherapy was administered to stage IV and type C one month after operation. For patients with tumor nodules found on the pleural surface, cytoreductive surgery was performed. After that, patients had both adjuvant radiation therapy and chemotherapy. Results: There were no peri-operative deaths. 19 cases were inoperable. 16.2% patients had postoperative complications: The proportions of type A, AB, B1, B2, B3, and C thymoma in this data were 0%, 22.4%, 26.4%, 30.4%, 20.8%, and 0% respectively in patients with MG. Microthymoma was identified in the paraneoplastic thymus of 3 patients. There were 198 patients followed up. There was no recurrence in patients with type A and a few patients with type AB, B1, B2, B3 and C recurred. The actuarial 5- and 10-year survival rates were 89.6% and 80.5% respectively. Within 5 years postoperatively, 6 of 16 deaths died of myasthenia crisis, 6 were attributable to inoperable tumors (stageIV) and type C thymoma. Conclusions: Surgical treatment to thymoma has a sound prognosis. Multimodality treatment of stage III or IV thymomas may be critical to improve the 5-year survival rate. MG seldom occurs in type A and C thymoma. The main cause of death is myasthenia crisis for thymoma patients with MG and stage IV and /or type C for thymoma patients without MG.

Abstract Background: We compared outcomes and toxicities between concurrent retrograde super-selective intra-arterial chemoradiotherapy (IACRT) and concurrent systemic chemoradiotherapy (SCRT) for gingival carcinoma (GC).　Methods: We included 84 consecutive patients who were treated for non-metastatic GC ≥ stage III, from 2006 to 2018, in this retrospective analysis (IACRT group: n=66; SCRT group: n=18).Results: The median follow-up time was 24 (range: 1–124) months. The median prescribed dose was 60 (6–70.2) Gy (IACRT: 60 Gy; SCRT: 69 Gy). There were significant differences between the two groups in terms of 3-year overall survival (OS; IACRT: 78.8%, 95% confidence interval [CI]: 66.0–87.6; SCRT: 50.4%, 95% CI: 27.6–73.0; P = 0.039), progression-free survival (PFS; IACRT: 75.6%, 95% CI: 62.7–85.2; SCRT: 42.0%, 95% CI: 17.7–70.9; P = 0.028) and local control rates (LC; IACRT: 77.2%, 95% CI: 64.2–86.4; SCRT: 42.0%, 95% CI: 17.7–70.9; P = 0.015). In univariate analysis, age ≥ 65 years, decreased performance status (PS) and SCRT were significantly associated with worse outcomes (P < 0.05). In multivariate analysis, age ≥ 65 years, clinical stage IV, and SCRT were significantly correlated with a poor OS rate (P < 0.05). Patients with poorer PS had a significantly worse PFS rate. Regarding acute toxicity, 22 IACRT patients had grade 4 lymphopenia, and osteoradionecrosis was the most common late toxicity in both groups.Conclusions: This is the first report to compare outcomes from IACRT and SCRT among patients with GC. ALL therapy related toxicities were manageable. IACRT is an effective and safe treatment for GC.

The Impact

Adrenocortical carcinoma (ACC) is a rare endocrine malignancy with a dismal prognosis. When diagnosed in advanced stages of the disease, the outcomes of surgical resection are not well understood. The objective of this study is to determine the impact of surgery in patients with advanced ACC. Using the Surveillance, Epidemiology and End Results database, we identified patients diagnosed with Stage III and IVACC between 1988 and 2009. A total of 320 patients with Stage III and IV disease were included in our analysis. In patients treated with surgical resection, the Stage III 1- and 5-year survival rates were 77 and 40 per cent, respectively, whereas the Stage IV 1- and 5-year survival rates were 54 and 27.6 per cent, respectively. Patients treated without surgery had poor survival at 1 year for both Stage III (13%) and Stage IV (16%) ( P < 0.01 compared with the surgical groups). Lymph node dissection was performed in 26 per cent of the patients with advanced ACC and was associated with improved survival in univariate analysis of Stage IV patients. Overall, our results indicate that favorable survival outcomes can be achieved even in patients with Stage III and IV disease and surgery should be considered in patients with advanced ACC.

Objective: Differentiated thyroid cancer (DTC), the most common subtype of thyroid cancer, has a relatively good prognosis. The 8th edition of the American Joint Committee on Cancer (AJCC) pathologic tumor-node-metastasis (T [primary tumor size], N [regional lymph nodes], M [distant metastasis]) staging system did not take the T stage into consideration in stage IV B DTC patients. We evaluated the prognostic value of the T stage for advanced DTC survival. Methods: DTC cases that were considered stage IV B in the AJCC 8th edition were extracted from the Surveillance, Epidemiology, and End Results database. T stage (AJCC 6th standard) was categorized into T0–2, T3 and T4. We analyzed overall survival (OS) and cancer specific survival (CSS) in the overall group as well as in pathologic subgroups. We used the Kaplan-Meier method and log-rank test for univariate analysis and the Cox regression model for multivariate analysis. Results: A total of 519 cases were extracted. Patients with earlier T stages showed significantly better OS and CSS in univariate analysis. T stage was an independent prognostic factor for both OS and CSS in multivariate analysis. Subgroup analysis in papillary and follicular thyroid cancer showed that T4 was an independent prognostic factor for both OS and CSS. Conclusion: AJCC 8 stage IV B DTC patients could be further stratified by T stage. Further studies with larger samples and AJCC 8 T stage information are necessary.

7644 Background: With increasing use of MRI and PET to stage NSCLC, the demographics, performance status and distribution of metastases at diagnosis in this patient (pt) population are changing; it is important to reassess the prognostic roles played by baseline clinical variables in the modern therapeutic era. Methods: We retrospectively evaluated the charts of 189 consecutive, unselected pts with stage IV NSCLC seen and followed at the Fox Chase Cancer Center between Oct 2000 and Aug 2003. Data on a variety of pt variables including demographics, histology, metastases, key laboratory tests and treatment were compiled. We intended to identify those that played statistically significant prognostic roles. Results: Median age at diagnosis was 62 years; 77% of pts had PS 0–1 at first presentation. 58% had single organ metastasis; 35% had metastases to the brain (half of these had brain only and a third had solitary brain metastasis). 51% of all pts received palliative radiation to the brain at some point after dx. Overall median survival was 10.8 months. The 1-yr, 2-yr, 3-yr and 4-yr overall survival rates were 44.2%, 21.9%, 11.6% and 7.8% respectively. On multivariate analysis, statistically significant negative prognostic factors included PS ≥ 2 (HR: 1.9, 95% CI: 1.1–3.3), serum albumin ≤ 3 (HR: 1.7, 95% CI: 1.1–2.8) and metastases to > 1 organ (HR: 1.6, 95% CI: 1.03–2.3). Bone and liver metastases, though associated with worse survival in univariate analysis, were not found to be independent predictors of survival. Gender had no bearing on outcome. Conclusions: Survival rates in this advanced NSCLC cohort equal or exceed contemporaneous ECOG figures. PS, serum albumin and number of organs with metastases are independent prognostic factors in NSCLC. The increasing detection of brain metastases at 1st presentation of metastatic NSCLC suggests that the role of prophylactic cranial irradiation in the management of early NSCLC should be explored. No significant financial relationships to disclose. [Table: see text]

The Impact

10042 Background: 40-50% of sarcomas become metastatic. Median survival of metastatic patients has improved over time. The probably multifactorial reasons for such improvement are not fully clear. Noteworthy, for patients with a controlled primary and a limited number of lung metastases, complete resection of their metastases yields survival rates of up to 40% at three years. Advances in surgery, radiotherapy and radiofrequency have fostered the use of local treatments for various metastatic sites (lung, liver, spine...). Methods: A multicentric retrospective study of the Groupe Sarcome Francais (GSF-GETO); approved by the nationally-review board and ethical committee, was conducted to assess the impact of local ablative treatment on overall survival. Patients who had had oligometastases (any site, 1-5 synchronous metastases) at diagnostic or during the course of disease between 2000 and 2010 were included. Results: Median age of the 243 oligometastatic sarcoma patients was 53 years-old (11-86). Patients had grade I, II and III in 7.5%, 29.6% and 63.3% of cases, respectively with various histologies. 69% of patients underwent local ablative treatment of metastases. Median follow-up was 59 months (4-212) for living patients. Median overall survival was 51 months (1-348). On univariate analysis, grade, histology, absence of chemotherapy, local ablative treatment (surgery, irradiation, radiofrequency or chemoembolisation) correlated with survival but not age or site of oligometastasis. On multivariate analyses, grade (hazard ratio HR 0.12 [CI95 0.3-0.6]) and local ablative treatment (HR 3.8 [CI95 2.1-7.1]) remained significant. Conclusions: Local ablative treatment of metastases is associated with better survival in sarcoma patients with oligometastatic disease. The role of the locoregional treatment of metastases and its impact on quality of life should be assessed prospectively.

e20019 Background: Historically, melanoma with brain metastases has a poor prognosis and is a major contributor to patient morbidity and mortality. Recently, the use of ipilimumab has improved overall survival in stage IV melanoma; however, the outcome of patients with brain metastases remains unclear. In this retrospective medical record review, we report the outcome of patients with stage IV melanoma with brain metastases treated with ipilimumab and brain stereotactic radiosurgery (SRS). Methods: All patients with metastatic melanoma treated with ipilimumab from April 2010 to March 2012 were identified and stratified by presence (A) or absence (B) of brain metastases. All patients with brain metastases received SRS. Performance status, dates of stage IV diagnosis, brain SRS and cycle 1 of ipilimumab administration were recorded. We used the Disease Specific Graded Prognostic Assessment (DS-GPA) to estimate the predicted survival. Overall survival was defined as time (months) from the date of the stage IV diagnosis and the time of ipilimumab administration to death or last follow-up. Survival curves were estimated using the Kaplan-Meier method, and compared using a two-tailed log-rank test. Results: Twelve of 30 patients treated with ipilimumab had brain metastases. Median age was 66 years. Median DS-GPA score was 3 (estimated mean survival of 8.7 months). Four patients (33%) in group A and 6 patients (33%) in group B died as of last follow-up. Median number of SRS treatment was 1 (1 to 4), and median total treated lesions were 3 (1-14). Median survivals from date of Stage IV for A and B were 29.1 and 32.9 months, respectively (p=0.67). The estimated 2 year survival rates from date of cycle 1 ipilimumab administration for A and B were 58% (95% CI: 32-100%) and 55% (95% CI: 32-93%), respectively. Ten out of 12 patients in group A maintained an ECOG PS of 0-1 as of last follow-up. Conclusions: Survival of patients with melanoma brain metastases treated with ipilimumab combined with SRS may be comparable to patients without brain metastases. Ipilimumab and SRS do not seem to adversely impact quality of life.

181 Background: To compare the efficacy of docetaxel plus FOLFOX4 to FOLFOX4 as adjuvant chemotherapy for gastric cancer patients. Methods: 320 patients with stage IB-IV (M0) gastric cancer were enrolled into the retrospective study. All patients received a total or subtotal gastrectomy with at least D1 lymph nodes dissection. 193 patients received FOLFOX4 as adjuvant chemotherapy. 127 patients received biweekly docetaxel plus FOLFOX4 (DOF regimen) as adjuvant chemotherapy. Docetaxel was administered at 40 mg/m2 on day 1, followed by FOLFOX4 regimen. Both of the regimens were repeated every 2 weeks for a maximum of 12 cycles. Results: In comparison with patients in FOLFOX4 group, patients in DOF group were relatively younger (p=.001), with more advanced disease in pN stage (p=.035) and pTNM stage (p=.031), received more cycles of adjuvant chemotherapy (p=.004), and had a higher percentage of adjuvant radiation (p =.002). After adjustment of unbalanced variables as mentioned above, no statistical difference was observed between DOF group and FOLFOX4 group in terms of 3-year disease-free survival (54% vs 69%, p = 0.100, HR 1.362, 95% CI (0.943-1.967)) and 3-year overall survival(70% vs 72%, p = 0.810, HR 1.049, 95% CI (0.711-1.548)). Stratified analysis according to clinicopathologic characters showed that there were almost no statistical differences of 3-year overall survival rates between two groups, except the primary site (middle 1/3) (p =.025) and pTNM stage (IIb stage) (p =.035) in favor of FOLFOX4 group. The incidences of grade 3/4 adverse events were obviously higher in DOF group than in FOLFOX4 group,including decreased appetite (18.1% V 10.4%, P = 0.046), diarrhea (4.7% V 0%, p=0.004 ), hypersensitivity reactions to oxaliplatin (3.1% V 0%, p=0.024) and neutropenia (47.3% V 31.6%, p=0.004). Conclusions: Compared to FOLFOX4 regimen, adjuvant docetaxel plus FOLFOX4 did not show significant survival advantages in gastric cancer patients. However, a more serious toxicity profile was observed in docetaxel plus FOLFOX4 arm. Further studies are needed to decide whether triplet regimen is appropriate as adjuvant chemotherapy of gastric cancer.

e18128 Background: PDAC has a rising incidence and relatively static mortality rates. Current cytotoxic regimens confer median survivals of 8.5- 11 months (Von Hoff, Conroy, et al. NEJM 2013, 2011). National Cancer Institute-designated Comprehensive Cancer Centers potentially allow greater access to multidisciplinary consultation for complex cancer care. Although the widespread benefits of NCICCCs are acknowledged, there is limited data demonstrating superior outcomes for patients treated at these centers. Methods: Patients with stage IV PDAC, diagnosed between 01/01/13 and 12/31/14, were identified and followed until death or 12/31/2016. These patients had care centralized to MSKCC and the analysis was conducted to evaluate key patient (pt) and disease characteristics, systemic therapies and outcomes.Survival times were calculated from the date of diagnosis. Results: N=391 pts identified, 210 males (54%), 181 females (46%). Median age 66 years (range 27-91). Table 1 outlines key points. For entire cohort, median overall survival (mOS): 11.4 + 9 months, 1-year (yr) and 2-yr survival rates (SR) of 48% and 15.1% respectively. N= 165 (42%) received mFOLFIRINOX-based regimen as 1st-line therapy with mOS 13.2 + 8.9 months, 1-yr and 2-yr SR of 59.4.% and 20% respectively. N= 118 (30.1%) received gemcitabine + nab-paclitaxel- based regimen as 1st line therapy had a mOS of 11.6 + 9 months with 1-yr and 2-yr SR of 49.1% and 16.2% respectively. Conclusions: At MSKCC, a major referral center for PDAC, outcomes for stage IV disease compare favorably to contemporary trial outcomes with notable 2-yr survivorship (long-term survival analysis of MPACT trial showed 1-yr and 2-yr SR of 35% and 10% respectively). Contributing factors likely reflect multidisciplinary expertize, patient selection and biases. Centralized care for complex illnesses may improve outcomes. [Table: see text]
