Thymic Tumors

A complete resection of thymic tumors is known to be the most important prognostic factor, but it is often difficult to perform, especially in advanced stages. In this study, 73 patients with advanced thymic tumors of UICC stages III and IV who underwent radical resection were examined retrospectively. The primary endpoint was defined as the postoperative resection status. Secondary endpoints included postoperative morbidity, mortality, recurrence/progression-free, and overall survival. In total, 31.5% of patients were assigned to stage IIIa, 9.6% to stage IIIb, 47.9% to stage IVa, and 11% to stage IVb. In stages III a R0 resection was achieved in 53.3% of patients. In stages IV a R0/R1 resection was documented in 76.7% of patients. Surgical revision was necessary in 17.8% of patients. In-hospital mortality was 2.7%. Median recurrence/progression-free interval was 43 months (p = 0.19) with an overall survival of 79 months. The 5-year survival rate was 61.3%, respectively. Median survival after R2 resection was 25 months, significantly shorter than after R0 or R1 resection (115 months; p = 0.004). Advanced thymic tumors can be resected with an acceptable risk of complications and low mortality. In stage III as well as in stage IV the promising survival rates are dependent on the resection-status.

The overall survival (OS) rate of extrahepatic cholangiocarcinoma (ECC) remains much lower than that for other gastrointestinal malignancies. A variety of factors have been used to predict prognosis after surgical resection for ECC, but no consensus has been reached. Therefore, this study sought to identify useful prognostic factors for patients with ECC. In our institution, within the study period, 76 patients received surgical resection for mid to distal cholangiocarcinoma. Clinicopathological data were retrospectively collected, along with survival and prognosis. In multi-variate analysis for OS, ductal margin status (P = 0.008) and pT category (P < 0.02) presented independent predictors of survival. In the R0 resection group, N stage and adjuvant chemotherapy presented independent predictors of recurrence in the multivariate model. The three- and five-year survival rates were significantly better in patients with negative ductal margins (77.% at three years and 63.6% at five years) than in those with positive ductal margins (33.3% at three years and 25.0% at five years) (P < 0.05). Survival rates were similar between cases of R0 resection without gemcitabine-based chemotherapy and R1 resection with gemcitabine-based chemotherapy (P = 0.6193, Log-rank test). However, survival rates between R0 resection with gemcitabine-based chemotherapy and R1 resection with gemcitabine-based chemotherapy were significantly different (P = 0.0086, Log-rank test). For good prognosis, radical resection to ensure adequate margin may be recommended for middle common bile duct cancer. In addition, regardless of margin negativity, gemcitabine-based chemotherapy is recommended for prolongation of relapse-free time and OS time.

ObjectiveThe revised version of the International Federation of Gynaecology and Obstetrics (FIGO) staging system (2014) for epithelial ovarian cancer includes a number of changes. One of these is the division of stage IV into 2 subgroups. Data on the prognostic and predictive significance of this classification are scarce. The effect of neoadjuvant chemotherapy (NACT) versus primary debulking surgery (PDS) in relation to the subclassification of FIGO stage IV is also unknown.MethodsWe used data of the EORTC 55971 trial, in which 670 patients with previous stage IIIC or IV epithelial ovarian cancer were randomly assigned to PDS or NACT; 160 patients had previous stage IV. Information on previous FIGO staging and presence of pleural effusion with positive cytology were used to classify tumors as either stage IVA or IVB. We tested the association between stage IVA/IVB and survival to evaluate the prognostic value and interactions between stage, treatment, and survival to evaluate the predictive performance.ResultsAmong the 160 participants with previous stage IV disease, 103 (64%) were categorized as stage IVA and 57 (36%) as stage IVB tumors. Median overall survival was 24 months in FIGO stage IVA and 31 months in stage IVB patients (P = 0.044). Stage IVB patients treated with NACT had 9 months longer median overall survival compared with IVB patients undergoing PDS (P = 0.025), whereas in IVA patients, no significant difference was observed (24 vs 26 months, P = 0.48).ConclusionsThe reclassification of FIGO stage IV into stage IVA or IVB was not prognostic as expected. Compared with stage IVA patients, stage IVB patients have a better overall survival and may benefit more from NACT.

Abstract   Circumferential resection margins (CRM) of an esophagectomy specimen for oesophageal cancer is a key prognostic factor of overall survival (OS). This retrospective study aims to compare OS of post-esophagectomy patients with CRM of &gt;1 mm (R0) and &lt; 1 mm (R1) with further subgroup analysis of locally advanced T3R0 vs T3R1 resection. Methods A total of 110 esophagectomies conducted between 2010 and 2020 were analysed. We recorded R stage based on pathological CRM &gt;1 mm (R0) or &lt; 1 mm (R1). OS was calculated from the day of surgery to day of death or otherwise censored. All patients underwent multimodal therapy including chemotherapy and similar pre-surgical and post-surgical management. 58 of these patients with pT3 stage esophageal cancer (EC) were selected and compared. Statistical analysis was carried out using SPSS. Results Of 110 patients, 78 (71.5%) patients had a R0 resection. Mean OS in R0 resections was 73 months (6 years) compared to 25.2 months (2 years) in R1 resection (p = 0.001). 58 of the 110 patients were pathological stage T3(pT3) despite downstaging with chemotherapy showing the burden of advanced disease. In patients with stage pT3 (n = 58), 32 patients were R0 resections, and 26 patients had R1 resections. Mean OS in T3R0 resections was 51.5 months compared to 28.5 months in T3R1 resection. OS comparison is significant (p = 0.011). Conclusion This study emphasizes the importance of clear CRM in all patients and especially in locally advanced pT3/T4a esophageal cancer in achieving long term survival. Techniques used to ensure a clear CRM such multimodality therapy combined with surgical radical resection concepts such as mesoesophagectomy should be employed.

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.

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]

Purpose We update Radiation Therapy Oncology Group trial 8911 (USA Intergroup 113), a comparison of chemotherapy plus surgery versus surgery alone for patients with localized esophageal cancer. The relationship between resection type and between tumor response and outcome were also analyzed. Patients and Methods The chemotherapy group received preoperative cisplatin plus fluorouracil. Outcome based on the type of resection (R0, R1, R2, or no resection) was evaluated. The main end point was overall survival. Disease-free survival, relapse pattern, the influence of postoperative treatment, and the relationship between response to preoperative chemotherapy and outcome were also evaluated. Results Two hundred sixteen patients received preoperative chemotherapy, 227 underwent immediate surgery. Fifty-nine percent of surgery only and 63% of chemotherapy plus surgery patients underwent R0 resections (P = .5137). Patients undergoing less than an R0 resection had an ominous prognosis; 32% of patients with R0 resections were alive and free of disease at 5 years, only 5% of patients undergoing an R1 resection survived for longer than 5 years. The median survival rates for patients with R1, R2, or no resections were not significantly different. While, as initially reported, there was no difference in overall survival for patients receiving perioperative chemotherapy compared with the surgery only group, patients with objective tumor regression after preoperative chemotherapy had improved survival. Conclusion For patients with localized esophageal cancer, whether or not preoperative chemotherapy is administered, only an R0 resection results in substantial long-term survival. Even microscopically positive margins are an ominous prognostic factor. After a R1 resection, postoperative chemoradiotherapy therapy offers the possibility of long-term disease-free survival to a small percentage of patients.

Background: Ovarian cancer has the highest mortality rate among all the other gynaecologic malignancies. Stage I cancer treated with surgery and adjuvant chemotherapy report a 5-year overall survival of 95% while this value significantly drops to 25% in stage IIIC and IV patients. Unfortunately, effective screening methods to detect the early cancer are yet to be identified.Methods: All the patients diagnosed to have epithelial ovarian carcinoma from January 2012 to December 2014 at our center with pre-treatment CA-125 levels were included in this retrospective study. Disease free survival and overall survival were tabulated either by telephonic conversation or on a regular follow up visit to the hospital.Results: Among the 69 patients enrolled 38% of the patients were in the age group of 50-60 years. 58% of patients had stage 3 disease up front. mean CA-125 levels were lowest in patients with stage I disease and the highest in stage IV disease with a statistically significant rise in CA-125 levels with the stage of disease. Only 52% of the patients completed the treatment as per protocol. There was a significant negative co relation between the CA-125 levels and survival rates in both the sub groups of patients who received complete and incomplete treatment respectively.Conclusions: In the present study we would like to conclude that pre-operative CA-125, which has already been included in the screening algorithms like ROCA, has a greater potential to become a prognostic marker. Present study is limited by the small number of patient’s and thus larger multi centric studies with better randomization could establish the role of CA-125 as a prognostication marker.

e15745 Background: Current guidelines determine the resectability of PDAC by evaluating the contact of the tumor to peripancreatic vasculature. We wanted to evaluate the influence of this distance of the tumor to peripancreatic arteries on the overall survival of patients with primary resection of pancreatic ductal adenocarcinoma. Methods: Preoperative radiographs of 208 consecutive patients after distal pancreatectomy and/or pancreatoduodenectomy operated between 2007 and 2014 were included in the analysis. In reconstructions of CT and MRI data 90° planes to the centerline of the celiac trunc (CT), hepatic artery(HA) and superior mesenteric artery(SMA) were computed with Aquarius Intuition Viewer (V4.4.11, Terarecon). The closest distance between the tumor and the CT /HA and SMA was determined by an experienced pancreatic surgeon and radiologist independently and upon a deviation greater than 3 mm consent was reached by additional review in 33,2% (69/208) of the cases. Results: 176 CT and 32 MRI scans of 208 patients were evaluated. 2.4 % (5/208) of the radiographs were excluded due to insufficient quality. Average distance of the tumor to the CT/HA and SMA was 16.3 and 6.5 mm for PD and 12.7 and 11.0 mm for DP. Distance between the artery and the tumor did not influence the R0 resection rates (overall R0 > 1mm resection margin 64%) and median overall survival was 24.0 months after R0 resection and 13.5 months after R1 resection (log-rank test P < 0.05). Borderline resectable patients (n = 57) showed a median survival of 13.4 months, patients with their tumor 1-5mm distant to the closest artery (n = 65) and greater than 5 mm distance (n = 81) showed a median survival of 20.3 and 32.9 months respectively. Patients with 0-5 and greater than 5 mm distance between arteries and tumor showed a survival benefit from R0 resection (R0/R1 0-5mm 20.3/13.5 months; > 5mm 37.3/12.8 months) while R0 resected borderline resectable patients showed a similar survival than R1 resected patients (R0 12.7months, R1 15.1 months). Conclusions: The negative resection margins in borderline resectable patients not increase the survival when compared to R1 resected patients. Patients with primary R0 resection and initially large distance of the tumor to peripancreatic vasculature show a prolonged survival.

117 Background: The role of IP CTX in pts with GC and PC is unclear. The PHOENIX-GC phase III study (J Clin Oncol 2018;35:1922) did not show overall survival (OS) benefit for IP CTX plus systemic CTX while a retrospective French study suggested benefit for IP CTX and cytoreductive surgery (J Clin Oncol 36:8 [abstr]). Prolonged survival may be possible in pts with chemosensitive disease (dz). Methods: We reviewed GC pts diagnosed with PC (+ve cytology and/or gross dz) at diagnostic laparoscopy (DL). We identified pts treated with gastrectomy and IP floxuridine 1,000mg/ m2/leucovorin 240 mg/m2 ×3d q14d and pts who had CTX alone. Pts with visible dz on imaging were excluded. Progression-free survival (PFS) and OS were calculated from surgery date and estimated using Kaplan-Methods in surgery + IP CTX pts. Pt characteristics were compared using Fisher’s exact test and Wilcoxon Rank-Sum tests. Results: From 2000-2017, 18 pts had surgery + IP CTX (IP); 45 pts received CTX alone. Median age was 50 in IP pts and 65 in CTX only pts (p = 0.002); 94% of IP pts were ECOG PS 0/1 vs. 78% in CTX only pts (p = 0.16). 56% and 67% of pts had gross dz at DL in IP and CTX only pts respectively; remaining pts had +ve cytology only. IP pts received CTX (72% 5-FU/platinum based) for a median 3.3 months before repeat DL. 14/18 pts cleared dz; four pts with residual dz (1 +ve cytology only) had gross dz at baseline. Fourteen pts had R0 resection; 83% of tumors were ypT3-4N+. 4 pts had R1 resection; three had residual gross PC at DL. Pts received IP CTX for a median of 1 month post surgery. Median PFS and OS were 12.4 and 23 months respectively in surgery + IP CTX pts. While there was no difference in PFS in pts with -ve vs. persistently +ve cytology at repeat DL following CTX (15.5 vs. 4.7 months, p = 0.3), median OS was improved in pts who cleared cytology (29 vs. 8 months, p = 0.01). Median PFS and OS were 7 and 13.5 months respectively in CTX only pts. Conclusions: Surgery and IP CTX may have a role in highly select pts with GC and +ve cytology or small-volume gross dz. While survival was encouraging, no pt had OS > 5 years. Surgery and IP CTX may be considered in pts who have a -ve repeat DL after initial CTX. Survival in CTX only pts is comparable with stage IV pts enrolled on clinical trials.
