Rare Malignancy

326 Background: Hilar cholangiocarinoma (Klatskin tumor) is a rare malignancy which is best managed with surgical resection. The majority of patients, however, is unresectable at the time of diagnosis and generally has a poor outcome. The purpose of this study was to retrospectively evaluate the role of chemoradiotherapy (CCRT) for patients with unresectable hilar choloangiocarcinoma at a single institution. Methods: Between 2001 and 2008, a total of 33 patients with unresectable, nonmetastatic hilar cholangiocarcinoma treated at Taipei Veterans General Hospital were reviewed. All patients were to receive 3D-CRT with a median dose of 50.4 Gy (range, 39.6- 60) at 1.8-2 Gy per fraction per day. Sixteen patients also received bolus 5-fluorouracil (5-FU) CCRT (500 mg/m2/d for 3 days repeated every 2 weeks during radiotherapy for 6 weeks). Survivals were estimated by the Kaplan-Meier method and compared by log-rank test. Results: There were 21 males and 12 females, with a median age of 71 years (range, 29 - 81). The median follow-up time was 10.4 months (range, 1 – 42.3) for all patients with the 1- and 2-year survival rates of 45% and 12%, respectively. The median overall survival (OS) and progression-free survival (PFS) were 13.5 months and 10.2 months for the CCRT group, and 10.4 months and 6.5 months for the RT alone group (p = 0.36 and p = 0.28, respectively). Adverse events were similar in thetwo groups with 14 patients (42%) developed grade 1-2 gastrointestinal toxicity during RT. Locoregional progression was observed in 26 patients (79%) and distant metastases in 9 patients (27%). All patients experienced disease progression and had died at time of analysis. Conclusions: The outcome remains poor for unresectable hilar cholangiocarcinoma despite aggressive combined modality treatment. Although not statistically significant, our data showed CCRT provides longer OS and PFS in patients with unresectable hilar cholangiocarcinoma compared to RT alone. Locoregional progression is the main problem for this disease and the efficacy of adding chemotherapy or biologic agents needs to be further investigated.

8526 Background: In the phase 3 PACIFIC study of patients with unresectable, Stage III NSCLC without progression after chemoradiotherapy (CRT), durvalumab demonstrated significant improvements versus placebo in the primary endpoints of progression-free survival (HR, 0.52; 95% CI, 0.42–65; P < 0.0001) and overall survival (OS; HR, 0.68; 95% CI, 0.53–0.87; P = 0.00251). Safety was similar and durvalumab had no detrimental effect on patient-reported outcomes. Here, we report 3-year OS rates for all patients randomized in the PACIFIC study. Methods: Patients with WHO PS 0/1 (any tumor PD-L1 status) who received ≥2 cycles of platinum-based CRT were randomized (2:1), 1–42 days following CRT, to receive durvalumab 10 mg/kg intravenously every 2 weeks or placebo, up to 12 months, and stratified by age, sex, and smoking history. OS was analyzed using a stratified log-rank test in the ITT population. Medians and OS rates at 12, 24 and 36 months were estimated by Kaplan-Meier method. Results: In total, 713 patients were randomized of whom 709 received treatment (durvalumab, n = 473; placebo, n = 236). The last patient had completed the protocol-defined 12 months of study treatment in May 2017. As of January 31, 2019 (data cutoff), 48.2% of patients had died (44.1% and 56.5% in the durvalumab and placebo groups, respectively). The median duration of follow-up was 33.3 months (range, 0.2–51.3). Updated OS remained consistent with that previously reported (stratified HR 0.69, 95% CI, 0.55–0.86), with the median not reached (NR; 95% CI, 38.4 months–NR) with durvalumab versus 29.1 months (95% CI, 22.1–35.1) with placebo. The 12-, 24- and 36-month OS rates with durvalumab and placebo were 83.1% versus 74.6%, 66.3% versus 55.3%, and 57.0% versus 43.5%, respectively. After discontinuation, 43.3% and 57.8% in the durvalumab and placebo groups, respectively, received subsequent anticancer therapy (9.7% and 26.6% subsequently received immunotherapy). OS subgroup results will be presented. Conclusions: Updated OS data from PACIFIC, including 3-year survival rates, underscore the long-term clinical benefit with durvalumab following CRT and further establish the PACIFIC regimen as the standard of care in this population.

Abstract Objective: We examined the surgical approaches used at a single institution to treat petroclival meningioma and evaluated changes in method utilization over time. Methods: Craniotomies performed to treat petroclival meningioma between September of 1994 and July of 2005 were examined retrospectively. We reviewed 46 patients (mean follow-up, 3.6 yr). Techniques included combined petrosal or transcochlear approaches (15% of patients), retrosigmoid craniotomies with or without some degree of petrosectomy (59% of patients), orbitozygomatic craniotomies (7% of patients), and combined orbitozygomatic-retrosigmoid approaches (19% of patients). In 18 patients, the tumor extended supratentorially. Overall, the rate of gross total resection was 43%. Seven patients demonstrated progression over a mean of 5.9 years. No patients died. At 36 months, the progression-free survival rate for patients treated without petrosal approaches was 96%. Of 14 patients treated with stereotactic radiosurgery, none developed progression. Conclusion: Over the study period, a diminishing proportion of patients with petroclival meningioma were treated using petrosal approaches. Utilization of the orbitozygomatic and retrosigmoid approaches alone or in combination provided a viable alternative to petrosal approaches for treatment of petroclival meningioma. Regardless of approach, progression-free survival rates were excellent over short-term follow-up period.

e21032 Background: Previous studies suggested that MET exon 14 ( METex14) mutation regarding as a distinct subset was sensitive to MET-inhibitors, but poorly response to immunotherapy. Conversly, MET non-exon-14 (non-ex14) mutations including those undetermined functions and affecting the kinase or extracellular domains were found to be associated with the resistance to MET-inhibitors. However, therapeutic strategies for MET-non-ex14 mutant cancer are still largely unknown, and the relationship between MET-non-ex14 mutations and the efficacy of immune checkpoint inhibitors (ICIs) has never been reported. Using two public ICIs-treated cohorts, we aimed to assess the role of MET mutations including both METex14 and MET-non-ex14 mutations in NSCLC patients undergoing ICIs therapy. Methods: A total of 385 ICIs-treated NSCLC patients were enrolled to our study. MET mutations were defined as any nonsynonymous mutations, and we divided them into METex14 and MET-non-ex14 mutation subsets according to the mutated-position on MET. Kruskal-Wallis test was used to analyze the difference of tumor mutational burden (TMB) score, and the Fisher’s exact test was applied to compare the rates of durable clinical benefit (DCB). Log-rank test was used to analyze the differences between Kaplan-Meier survival curves. Results: In the entire cohort, we found that 17 patients (17/385, 4.4%) had MET mutations, most of which were pure METex14 mutations (10/17, 58.8%). The median TMB of patients in the entire NSCLC cohort was 6.89 mut/Mb. MET-non-ex14 mutant patients (7/385, 1.8%) possessed a significantly higher TMB than METex14-mutant (10/385, 2.6%) and MET wild-type (368/385, 95.6%) sub-cohorts, respectively (median TMB, 17.92 mut/Mb versus 4.17 mut/Mb, p = 0.008; 17.92 mut/Mb versus 6.96 mut/Mb, p = 0.01, respectively). DCB was more common in patients harbored MET-non-ex14 mutations than patients with METex14 mutations and MET wild-type (66.7% versus 14.3%, p = 0.103; 66.7% versus 29.9%, p = 0.075, respectively). We found that patients with MET-non-ex14 mutations had a numerically longer progression free survival (PFS) than those with METex14 mutations and MET wild-type (p = 0.169). Moreover, the PFS was significantly longer in MET-non-ex14-mutant subgroup than patients with METex14 mutations (median PFS, 9.1 versus 2.1 months, p = 0.025). Correspondingly, the overall survival (OS) was significantly longer in MET-non-ex14-mutant subgroup than their wild-type counterparts (median OS, not reached versus 11 months, p = 0.039). Additionally, patients with MET-non-ex14 mutations exhibited relatively better OS versus METex14-mutant patients (median OS, not reached versus 18 months, p = 0.175). Conclusions: MET-non-ex14 mutations were associated with higher TMB, improved DCB rate, and could act as a favorable prognostic biomarker in ICIs-treated NSCLC patients.

BACKGROUND: The relationship between endocan expression and outcome in patients with chronic liver disease is not fully understood.OBJECTIVE: To examine whether serum endocan level is predictive of outcome in patients with liver cirrhosis.METHODS: A total of 68 patients with liver cirrhosis were enrolled. Outcome predictors were analyzed using the Cox proportional hazards model. The overall survival rates were calculated using the Kaplan-Meier method, and differences were evaluated using the log-rank test.RESULTS: During the median follow-up period (7.1 years), nine patients had hepatocellular carcinoma (HCC) and 10 patients died. Of the deceased patients, nine died due to hepatic decompensation or associated conditions. No significant factors were found to be predictive of the occurrence of HCC. In contrast, an elevated serum endocan level (≥2.0 ng/mL; HR 2.34 [95% CI 1.05 to 7.03]; P=0.037) and high Child-Pugh grade B/C (HR 2.65 [95% CI 1.30 to 6.89; P=0.006) were predictive of poor survival. Kaplan-Meier analysis revealed that the respective cumulative survival rates at five and 10 years were 97.1% and 87.4% in patients with serum endocan levels <2.0 ng/mL and 85.8% and 64.4% in patients with levels ≥2.0 ng/mL (P=0.009), respectively. Moreover, the cumulative survival rates were significantly different among the patient groups divided according to serum endocan level and Child-Pugh grade (P=0.002).CONCLUSION: These findings suggest that serum endocan level may be a survival predictor for patients with liver cirrhosis.

Abstract Background To explore the survival and side effects of repeated CyberKnife stereotactic body radiation therapy (CK-SBRT) on hepatocellular carcinoma patients. Methods 24 HCC patients were collected at The Fifth Medical Center of PLA General Hospital from November 2011 to July 2016. They received second-course CK-SBRT with a prescribed dose of 50(48–55) Gy/5-8fx, and a single dose of 10 (7–11) Gy/fx. Cumulative overall survival rates (OS), progression-free survival rates (PFS) and local control rates (LC) were calculated by Kaplan-Meier method. Results All patients finished their radiotherapy plans. The 1-,2- and 3-year cumulative OS rate were 95.8,81.1 and 60.8%. The 1-,2- and 3-year LC rate were 95.5,90.7 and 90.7%, respectively. The 1-, 2- and 3-year PFS were 74.8, 49.2 and 39.4%, respectively. 16 patients complained of fatigue during second-course therapy, 2 patients showed Grade 2 gastrointestinal reaction, 1 patient was diagnosed radiation-induced liver disease and none died. PFS was significantly higher in the interval time < 12 months group than in the interval time ≥ 12 months group (p = 0.030). Conclusions It is preliminarily believed that re-CK-SBRT is an effective and safe treatment for HCC patients, but the treatment criteria should be strictly controlled.

Abstract Colorectal cancer (CRC), the second most common cancer globally, resulted in 881,000 deaths in 2018. Toll-like receptors (TLRs) are crucial to detecting pathogen invasion and inducing the host’s immune response. This study aimed to explore the prognostic value of TLR2 and TLR4 tumor expressions in colorectal cancer patients. We studied the immunohistochemical expressions of TLR2 and TLR4 using tissue microarray specimens from 825 patients undergoing surgery in the Department of Surgery, Helsinki University Hospital, between 1982 and 2002. We assessed the relationships between TLR2 and TLR4 expressions and clinicopathological variables and patient survival. We generated survival curves using the Kaplan-Meier method, determining significance with the log-rank test. Among patients with lymph node–positive disease and no distant metastases (Dukes C), a strong TLR2 immunoactivity associated with a better prognosis (p < 0.001). Among patients with local Dukes B disease, a strong TLR4 immunoactivity associated with a worse disease-specific survival (DSS; p = 0.017). In the multivariate survival analysis, moderate TLR4 immunoactivity compared with strong TLR4 immunoactivity (hazard ratio (HR) 0.66, 95% confidence interval (CI) 0.49–0.89, p = 0.007) served as an independent prognostic factor. In the multivariate analysis for the Dukes subgroups, moderate TLR2 immunoactivity (HR 2.63, 95% CI 1.56–4.44, p < 0.001) compared with strong TLR2 immunoactivity served as an independent negative prognostic factor in the Dukes C subgroup. TLR2 and TLR4 might be new prognostic factors to indicate which CRC patients require adjuvant therapy and which could spare from an unnecessary follow-up, but further investigations are needed.

Purpose To determine whether deleted in colon cancer (DCC) protein expression in colorectal cancer (CRC) metastases could predict outcome to palliative fluorouracil (FU)-based chemotherapy and to assess whether it is similar to that observed in the corresponding primary tumors. Patients and Methods DCC protein expression was assessed immunohistochemically on archival specimens of CRC metastases from 42 patients homogeneously treated by methotrexate-modulated bolus FU alternated to 6-S-leucovorin–modulated infused FU and was retrospectively correlated with patient characteristics and clinical outcome. In a subset analysis, DCC immunoreactivity was compared between metastatic CRC and the corresponding primary tumors and regional lymph node metastases. Results Positive immunoreactivity for DCC was found in 45% of patients. Eighteen (78%) of 23 patients for whom multiple samples were available displayed a similar pattern of expression in distant metastases and primary tumors. The median survival time was 14.3 months in patients without DCC expression and 21.4 months in patients with DCC-positive tumors (log-rank test, P = .04); the 2-year survival rates were 8.5% and 42.5%, respectively. Response rates to chemotherapy were not significantly different between the two groups. By multivariate analysis, DCC protein expression maintained its prognostic value and showed to be the single best predictor of survival, with a relative risk of 2.16. Conclusion Our results indicate that expression of the DCC protein in CRC metastases is similar to that observed in the corresponding primary tumors and represents a dominant predictor of survival in patients with unresectable, advanced CRC who are undergoing palliative FU-based chemotherapy.

185 Background: Obesity is one of the factors commonly associated with pancreatic cancer risk, but its prognostic role for survival is debatable. This study aimed to determine the role of BMI in treatment outcomes of pancreatic cancer patients (pts) undergoing surgical resection followed by adjuvant therapy. Methods: We retrospectively reviewed 165 consecutive pts with pancreatic cancer undergoing pancreaticoduodenectomy at Indiana University Hospital between 2004 and 2008. Fifty-three pts who received adjuvant treatment [gemcitabine alone (C-group): n=19; gemcitabine + radiotherapy (CRT-group): n=34] at our institution were included in the analysis. The Kaplan-Meier method was used to estimate the disease-free survival (DFS) and overall survival (OS); log-rank test was used to compare these outcomes between BMI groups (normal 18.5-24.99 kg/m2 vs. overweight/obese ≥ 25 kg/m2). Results: The sample comprised 53 pts (28 males; median age 62 yrs) with a median follow-up of 18.6 months (mos). Thirty pts (56.6%) had their BMIs recorded before the date of surgery, and 23 pts prior to starting adjuvant therapy. Two (3.8%) pts were underweight, 21 (39.6%) had a normal BMI and 30 (56.6%) were overweight/obese. There was no statistically significant difference in the median DFS of obese/overweight and normal BMI pts irrespective of adjuvant therapy (C or CRT) (14.47 vs. 11.80 mos; p= 0.111). Obese/overweight pts had a better median OS [25.2 vs. 14.6 mos; p=0.045 overall (25.7 vs. 16.9 mos; p= 0.143 for the CRT-group and 17.3 vs. 13.4 mos; p= 0.050 for the C-group)], 1-year survival [96.7% vs. 61.9%; p < 0.0001 overall (95% vs. 64.3%; p= 0.001 for the CRT-group, and 90% vs. 57.1%; p=0.016 with C)], and 2-year survival [52.6% vs. 25.4%; p < 0.0001 overall (60.0% vs. 30.0%; p=0.0001 for the CRT-group and 37.5% vs. 14.3%; p=0.0002 for the C-group)] than patients with normal BMI. Conclusions: In our experience, overweight/obese pts undergoing surgery followed by adjuvant therapy have better survival rates than patients with normal BMI.

e15098 Background: The lungs may be the sole site of mets in RCC.In this retrospective analysis, we analyzed the efficacy and safety of SU in mRCC pts from a global phase (ph) III study and a Japanese ph II study who had lung mets only at baseline. Methods: In the ph III study, treatment (Tx)-naïve mRCC pts were randomized 1:1 to SU 50 mg/d on a 4-weeks-on-2-weeks-off schedule (n=375) or interferon-a (IFN) 9 MU subcutaneously TIW (n=360). In the single-arm ph II study, Tx-naïve (n=25) and cytokine refractory (n=26) mRCC pts received the same SU Tx. In the ph III study, progression-free survival (PFS) and overall survival (OS) were estimated by Kaplan–Meier method, with median values compared by log-rank test. In both studies, objective response rate (ORR) was calculated with a two-sided 95% CI. PFS, OS, ORR, and safety were analyzed at final data cutoff. Results: In the ph III study, 31 (8%) and 42 (11%) pts in the SU and IFN groups, respectively, had lung mets only, compared with 12 (24%) in the ph II study. Baseline characteristics in lung mets pts were similar to all pts. In lung mets pts from the ph III study, ORR was higher with SU than with IFN (58.1% [95% CI: 39.1–75.5] vs. 19.0% [95% CI: 8.6–34.1]; P<0.001); there was a trend for longer median PFS with SU (14.1 vs. 7.8 months; HR: 0.531 [95% CI: 0.278–1.015]; P=0.0513); and median OS was comparable in both Tx subgroups (HR: 0.739 [95% CI: 0.335–1.628]; P=0.4507), although, at 25% of events, median OS was 22.9 months with SU vs. 15.8 months with IFN. In lung mets pts from the ph II study, ORR was 75.0% (95% CI: 42.8–94.5); at the time of analysis, median PFS and OS had not been reached; 4 pts (33%) had died due to any cause and 8 (67%) were alive without disease progression. The most common grade ≥3 SU-related AEs were fatigue, hand-foot syndrome, and diarrhea (all 19%) in the ph III study, and decreased platelets (100%), white blood cells (92%), and neutrophils (92%) in the ph II study. Conclusions: In the ph III study, Tx-naïve mRCC pts with lung mets only had significantly higher ORR and a trend for improved PFS and OS with SU compared with IFN. In the Japanese ph II study, ORR with SU was 75% in lung mets pts. Thus, 1st-line use of SU in mRCC pts with lung mets should be encouraged.

e13034 Background: This study assesses the impact of 6 cycles of adjuvant TMZ (conventional arm) versus 12 cycles (Extended arm) on Progression free survival (PFS), evaluate the toxicity and correlate the outcome with EGFR, P53 and MIB I labelling Index. Methods: Between December 2010 to October 2012, 36 post operative patients of Glioblastoma between age 18-65 years and Karnofsky Performance Score (KPS) ≥ 70 were included. Patients were randomized to receive Radiation with a dose of 60 Gray in 30 fractions over 6 weeks at 2 gray/fraction with concomitant TMZ (75 mg/m2/day) and Adjuvant therapy with either 6 or 12 cycles of TMZ(150 mg/m2 for 5 days, 28 days cycle). Patients were then assessed monthly clinically and imaged with MRI/CT every 3 monthly or when symptomatic. Toxicity was assessed using CTCAE version 3.0. Statistical Analysis was done using SPSS version 17.0.Kaplan Meier method was used for analysis of survival and log rank test was used for assessing the impact of variables on survival. Results: Of 36 patients, 18 patients were treated in each arm. Median age and KPS in both the arms was 47 years and 80 respectively. 44 % patients in the conventional arm and 50% patients in the Extended arm underwent complete surgical resection. 22% patients in the conventional arm and 28% in the extended arm did not complete their intended treatment. Grade ¾ Thrombocytopenia was seen in 16% in the extended arm and 0% in the conventional arm.EGFR, P 53 and MIB 1 >20% was seen in 26%, 45% and 20% patients respectively, overall. Median follow up was 18 months for both the arms (Range 10-23 months).At last follow up,8 patients in each arm had progression. Median PFS was 10 months vs.18.4 months (p 0.47) in conventional and extended arm respectively. On Univariate analysis, patients with KPS ≤ 80 had poorer survival than those >80 (Median PFS 9.5 Months vs. 16.9 Months; p 0.02).Age, extent of resection, EGFR, P53, MIB 1 did not significantly alter survival in the two treatment groups. Conclusions: Our study showed that schedule of extended Temozolomide is well tolerated by patients and tend to have better progression free survival. Further prospective randomized studies are needed to validate the findings of our study.
