We performed a multi-institutional analysis of 74 children with ependymoma to evaluate to what extent the clinical outcome of prospective trials could be reproduced in routine practice. The evaluation of factors that correlated with outcome was performed with a log rank test and a Cox proportional-hazard model. Survival was estimated with the Kaplan–Meier method. The majority of patients had brain tumours (89%). All had surgery as primary treatment, with adjuvant radiotherapy (RTH) and chemotherapy (CTH) applied in 78% and 57%, respectively. Median follow-up was 80 months and 18 patients died. Five- and 10-year overall survival (OS) was 83% and 73%. Progression was observed in 32 patients, with local recurrence in 28 cases. The presence of metastases was a negative prognostic factor for OS. Five- and 10-year progression-free survival (PFS) was 55% and 40%, respectively. The best outcome in patients with non-disseminated brain tumours was observed when surgery was followed by RTH (+/−CTH afterwards; p = 0.0001). Children under 3 years old who received RTH in primary therapy had better PFS (p = 0.010). The best outcome of children with ependymoma is observed in patients who received radical surgery followed by RTH, and irradiation should not be omitted in younger patients. The role of CTH remains debatable.

The Impact

BackgroundImmune-Oncology (IO) improves Overall Survival (OS) in metastatic Renal Cell Carcinoma (mRCC). The prognostic impact of previous Cytoreductive Nephrectomy (CN) and radical nephrectomy (RN), with curative intent, in patients treated with IO is not well defined. The aim of our paper is to evaluate the impact of previous nephrectomy on outcome of mRCC patients treated with IO.Methods287 eligible patients were retrospectively collected from 16 Italian referral centers adhering to the MeetUro association. Patients treated with IO as second and third line were included, whereas patients treated with IO as first line were excluded. Kaplan–Meier method and log-rank test were performed to compare Progression Free Survival (PFS) and OS between groups. In our analysis, both CN and RN were included. The association between nephrectomy and other variables was analyzed in univariate and multivariate setting using the Cox proportional hazard model.Results246/287 (85.7%) patients had nephrectomy before IO treatment. Median PFS in patients who underwent nephrectomy (246/287) was 4.8 months (95%CI 3.9–5.7) vs 3.7 months (95%CI 1.9–5.5) in patients who did not it (HR log rank 0.78; 95%CI 0.53 to 1.15; p = 0.186). Median OS in patients who had previous nephrectomy (246/287) was 20.9 months (95%CI 17.6–24.1) vs 13 months (95%CI 7.7–18.2) in patients who did not it (HR log rank 0.504; 95%CI 0.337 to 0.755; p = 0.001). In the multivariate model, nephrectomy showed a significant association with OS (HR log rank 0.638; 95%CI 0.416 to 0.980), whereas gland metastases were still associated with better outcome in terms of both OS (HR log rank 0.487; 95%CI 0.279 to 0.852) and PFS (HR log rank 0.646; 95%CI 0.435 to 0.958).ConclusionsIO treatment, in patients who had previously undergone nephrectomy, was associated with a better outcome in terms of OS. Further prospective trials would assess this issue in order to guide clinicians in real word practice.

The optimal tumor marker for predicting the prognosis of advanced thymic carcinoma (ATC) remains unclear. We conducted a multi-institutional retrospective study of patients with ATC. A total of 286 patients were treated with chemotherapy. Clinicopathological information, including serum tumor markers, was evaluated to determine the overall survival (OS) and progression-free survival (PFS). The carcinoembryonic antigen, cytokeratin-19 fragment, squamous cell carcinoma (SCC) antigen, progastrin-releasing peptide, neuron-specific enolase (NSE), and alpha-fetoprotein levels were evaluated. In the Kaplan–Meier analysis, the OS was significantly shorter in the patients with elevated NSE levels than in those with normal NSE levels (median, 20.3 vs. 36.8 months; log-rank test p = 0.029; hazard ratio (HR), 1.55; 95% confidence interval (CI), 1.05–2.31 (Cox proportional hazard model)); a similar tendency regarding the PFS was observed (median, 6.4 vs. 11.0 months; log-rank test p = 0.001; HR, 2.04; 95% CI, 1.31–3.18). No significant differences in the OS and PFS were observed among the other tumor markers. In both univariate and multivariate analyses of the patients with SCC only, the NSE level was associated with the OS and PFS. Thus, the NSE level may be a prognostic tumor marker for thymic carcinoma, regardless of histology.

We aimed to gain more evidence regarding the feasibility, toxicity, and oncological outcome of primary brachytherapy in patients with medically inoperable endometrial cancer. Thirteen patients receiving primary brachytherapy ± external beam radiotherapy (EBRT) for endometrial cancer due to medical inoperability were identified. The Kaplan–Meier method was used to estimate overall survival (OS), progression-free survival (PFS), and local failure-free survival (LFFS). Univariate outcome analyses were performed using the log-rank test. Peri-interventional complications, acute and chronic toxicities were evaluated. Additionally, we performed a Pubmed search and review of the literature of the last 10 years. Mean age at time of diagnosis was 73.9 years (60.4–87.1 years). Eleven patients were staged FIGO IA/B and one patient each with FIGO IIIA and IIIC. Kaplan–Meier-estimated 2-/5-year LFFS were 76.2%/56.4%, respectively. High grading correlated with a worse LFFS (p = 0.069). Kaplan–Meier-estimated 2-/5-year PFS were 76.9%/53.8% and 2-/5-year-OS were 76.9%/69.2%, respectively. No acute toxicities > grade II and only two late toxicities grade II/III occurred. We observed three peri-interventional complications. The available evidence suggests high rates of local control after definitive brachytherapy for inoperable endometrial cancer with a favorable toxicity profile. Definitive brachytherapy +/− EBRT should be considered as the preferred approach for this patient group.

Choice Of Treatment

Abstract BACKGROUND The EANO ESMO guidelines have proposed a classification of leptomeningeal metastases (LM) based on clinical (typical/atypical), cytological (positive/negative/equivocal) and MRI (A linear, B nodular, C linear and nodular, D normal or hydrocephalus only) presentation. Type I LM is defined by the presence of tumor cells in the cerebrospinal fluid (CSF) (confirmed LM) whereas type II LM is defined by typical clinical and MRI signs (probable or possible LM). Here we explored the clinical utility of these EANO ESMO LM subtypes for choice of treatment and outcome. PATIENTS AND METHODS We retrospectively assembled data from 254 patients with newly diagnosed LM from different solid tumors, including as main primary tumors breast cancer (n=98, 45%), lung cancer (n=65, 25.5%) and melanoma (n=51, 13.5%). Survival curves were estimated using the Kaplan-Meier method and compared by Log-rank test. RESULTS Median age at LM diagnosis was 56.5 years (range 20-82 years). Typical clinical LM symptoms or signs were noted in 225 patients (88.5%); only 13 patients (5%) were clinically asymptomatic. The most common MRI subtype was A seen in 117 patients (46%). Types B (n=33, 13%), C (n=54, 21%) and D (n=50, 19.5%) were less common. Tumor cells in the CSF were observed in 186 patients (73%) whereas the CSF was equivocal in 24 (9.5%) and negative in 44 (17.5%) patients. Patients with confirmed LM had inferior outcome than patients with probable or possible LM (p=0.0063). Type I patients had inferior outcome than type II patients (p=0.0019). Nodular disease was a negative prognostic factor in type II LM, but not in type I LM (p=0.0138). CONCLUSION The EANO ESMO LM subtypes are highly prognostic and should be considered for stratification and overall design of clinical trials.

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.

15042 Background: The value of second look surgery (SLS) in advanced epithelial ovarian cancer (EOC) has been has been questioned because performing this procedure has not been associated with a clear survival advantage.However, SLS continues to be the most accurate means of documenting the response to chemotherapy, and therfore still used in investigational protocols. The primary purpose of this study was to assess the levels of CA 125 after treatment, that could predict absence of disease at SLS. Methods: Between 1998 and 2003, 98 stage III EOC patients who underwent optimal cytoreductive surgery, completed 6 cycles of platinum/paclitaxel chemotherapy, and were NED (no evidence of disease: normal CA 125, normal physical and radiological examination) were included in this study. SLS was performed at 6–8 weeks from completion of primary therapy. Patients with disease present at SLS were considered to have persistent disease and received second line chemotherapy. Patient demographics, surgical and chemotherapy treatments, and CA 125 levels prior to start and at completion of primary treatment were collected retrospectively. Survival was estimated by the Kaplan-Meier method. Results: Forty seven out of 98 (48%) of optimally debulked patients who were NED at completion of primary therapy underwent SLS. Twenty-five out of 47 patients (53%) had evidence of disease at SLS and 22 out of 47 patients (47%) were NED at SLS. The median disease free survival was 42 months (95% CI 16, 81) in patients with negative SLS compared with 17 months (95% CI 9, 45) in patients who did not undergo SLS (p = 0.03). Estimated 5-year survival in patients with negative SLS was 90% compared to 50% in patients who did not undergo SLS (p = 0.05). CA 125 levels of ≤ 10 after completion of primary therapy was predictive of negative SLS (p < 0.05). Conclusions: SLS evaluation of disease status appears to be a more accurate than standard clinical evaluation in patients who are NED at completion of their primary therapy. Negative SLS also appears to be a predictor of improved disease free and overall survival. Furthermore, CA 125 ≤ 10 is predictive of negative SLS in patients who are NED after completion of primary therapy. No significant financial relationships to disclose.

8568 Background: High dose chemotherapy with autologous stem cells transplant (ASCT) is the gold standard in patients with relapsed/refractory HL. Response to induction chemotherapy (chemosensitive patients) plays a major role in prognosis, however the role of CR status after induction therapy has not been established. Methods: One hundred twenty one patients with relapsed/refractory HL received 4 courses of IGEV followed by single (N=59) or tandem (N=19) ASCT (Santoro et al., Haematologica 92, 2007). Response to IGEV was evaluated by Cheson criteria (1999).The aim of this study was to evaluate the role of CR versus no-CR to IGEV induction therapy on the outcome in terms of progression free survival (PSF) and overall survival (OS). Statistical analysis was performed by using the Kaplan-Meier method and Cox proportional hazard model. Results: IGEV induced an overall response rate of 75% with 46% of CR. In the univariate analysis favourable factors for outcome were CR vs no-CR to IGEV (PFS: p <0.001, OS: p 0.002), A vs B symptoms (PFS: p 0.003; OS: p 0.05), limited vs advanced stage (PFS: p 0.03; OS: p 0.03), and 1 vs≥2 previous chemotherapy lines (PFS: p 0.03, OS: p 0.02); response to last therapy (relapsed vs refractory) influenced PFS (p 0.03) but not OS (p 0.70). The multivariate analysis confirmed the favourable prognostic role of CR to IGEV (PFS HR: 2.5, CI 95%:1.3; 4.6 - OS HR 2.3, CI 95%:1.1;4.8) and of the number of previous chemotherapy lines (PFS HR:1.8, CI 95%:1.0;3.2 - OS HR 2.1, CI 95%:1.1;3.9). Conclusions: According to our data, we conclude that: 1. CR to IGEV is the strongest indicator of outcome in relapsed/refractory HL. 2. Achievement of CR to IGEV overcomes the role of initial disease status. 3. Efforts are warranted to increase the CR rate by induction therapy. No significant financial relationships to disclose.

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.

426 Background: In an open-label, phase IV study of sunitinib as 1st-line treatment (Tx) in Chinese pts with mRCC, median progression-free survival (PFS) and overall survival (OS) were 61.7 and 133.4 wk, respectively; objective response rate (ORR) was 31.1% (Ann Oncol 2012;23:851P). We retrospectively investigated correlations between on-Tx hypertension (HTN), neutropenia (N), and thrombocytopenia (T) and efficacy endpoints in pts from this trial. Methods: HTN was defined by either maximum systolic blood pressure ≥140 mm Hg (S-HTN) or maximum diastolic blood pressure ≥90 mm Hg (D-HTN). Using CTCAE assessment, N grade ≥2 and T grade >1 were used as cut-points for the analyses. Median PFS and OS were estimated by Kaplan−Meier method. The log-rank test was used to compare PFS and OS between groups with and without HTN, N grade ≥2, or T grade >1. Fisher’s exact test was used for ORR. Results: 102 pts were included in the HTN analyses, 60% with S-HTN versus 40% without S-HTN. Pts with S-HTN had greater ORR and longer PFS and OS than pts without S-HTN (Table). (Results were similar with D-HTN; see Table.) 103 pts were included in the N and T analyses, 67% with N grade ≥2 versus 33% with N grade <2, and 56% with T grade >1 versus 44% with T grade ≤1. Pts with N grade ≥2 had significantly greater ORR and significantly longer PFS and OS than pts with N grade <2 (Table). Pts with T grade >1 had greater ORR and significantly longer PFS and OS than pts with T grade ≤1 (Table). Conclusions: The developments of N grade ≥2 and T grade >1 during Tx with sunitinib were significantly associated with better outcome. Median PFS was more than twice as long for pts with S-HTN as for those without S-HTN, but the association did not reach statistical significance. [Table: see text]
