536 Background: The predictive role of metastatic sites in RCC pts treated with tyrosine kinase inhibitors (TKIs) is unclear. Aim of this study was to investigate whether first line SU and SO was associated to metastatic sites in terms of progression-free survival (PFS) and overall survival (OS). Methods: A retrospective cohort of consecutive metastatic RCC (mRCC) pts treated with TKIs at Istituto Nazionale Tumori of Milan was analyzed. All pts received at least one targeted therapy including: SO, SU, bevacizumab plus interferon-alfa, pazopanib or temsirolimus. The product limit method was used to estimate survival functions and Cox regression to estimate hazard ratios (HRs) and to test statistical interaction between sub-groups identified by different metastatic sites. Results: 358 mRCC pts receiving first line TKIs between January 2005 and October 2012 were evaluated. Overall 206 pts (58%) received SO while 103 pts (29%) SU. Median duration of treatment for SU and SO groups was 16 (95%CI 12.0-20.1) and 9 months (mo) respectively (95%CI 7.0-12.0). After a median follow-up of 56.1 mo (range: 1.0-93.2) median OS for SO group was 19.9 mo (95%CI 16.0-25.1) while OS for SU group was not yet defined. Noteworthy 142 pts (69%) treated with SO received SU at disease progression (PD) while 36 pts (35%) received SO at SU failure. A statistically significant interaction between first line treatment and metastatic sites was found for the liver site in terms of PFS and OS (PFS p=0.034; OS p=0.004). SU was associated with a 18% [95%CI (-37%)- 123%] higher risk of PD as compared to SO in pts with liver mets while pts without liver mets showed a 46% [95%CI (-61%)-(-24%)] decreased risk of PD as compared to SO. SU was associated with a 40% [95%CI (-32%)-187%] higher risk of death as compared to SO in pts with liver mets while pts without liver mets showed a 62% [95%CI (-76%)-(-40%)] decreased risk of death as compared to SO. The predictive role of liver mets was confirmed introducing the Motzer score (PFS p=0.084; OS p=0.009). Conclusions: mRCC pts with liver mets treated with first line SO showed a better outcome as compared to SU while pts without liver mets treated with first line SO showed a worse outcome as compared to SU.

e16554 Background: VETC has been described as an epithelial-to-mesenchymal-transition independent process of metastasis in hepatocellular carcinoma (HCC): endothelium covers small clusters of neoplastic cells allowing tumor dissemination. It has also been noted that VETC-positive HCCs benefit more from tyrosine kinase inhibitors (TKI) therapy. Interestingly, this type of angiogenesis was also found in RCC - and other cancers - and associated with poor prognosis. The objectives of the present study are: 1) to investigate the prognostic role of VETC in a cohort of primary consecutive RCC. 2) to model the predictive role VETC to TKI response in a cohort of metastatic RCC patients treated with sunitinib or pazopanib. Methods: The study was observational and retrospective. To evaluate the VETC effect on overall survival (OS) for Cox regression, with power .8, Hazard Ratio 2.35, proportion of subject VETC+ .4, proportion of events .6, correlation among covariates .4 and a type I error rate .5, the estimated sample size was n=89. We included consecutive patients undergoing surgery at our institution for primary RCC from 2005 to 2007, (Surgical Series; n=92 cases). Moreover, to investigate the possible role of VETC in predicting TKIs benefit, we considered all RCC patients treated with first line TKIs at our center (TKI Series; sunitinib, n = 39; pazopanib n = 17), and recorded the progression free survival (PFS). VETC was assessed with CD34 immunohistochemistry and defined as a continuous endothelial lining around tumor clusters. We used Bayesian probabilistic modeling to detect small effects and multilevel hierarchical modeling to reduce overfitting. Models were fit using Stan and R. The study was approved by institutional review board (n. 865/20) and registered on ClinicalTrials.gov. Results: VETC+ RCC had a worse prognosis in the Surgical Series, with a posterior probability density (PPD) of median OS of 88 months (mo) (standard deviation, SD: 16 mo) for VETC positive Vs 136 mo (SD: 26 mo) for VETC-; the expected loss of median OS was 48 mo (SD: 31 mo) for patients having a VETC + RCC. Conversely in the TKI Series, VETC+ RCC showed longer PFS compared to VETC- ones: with sunitinib a PPD of median PFS of 35 mo (SD:11 mo) for VETC+ Vs 19 mo (SD: 5 mo) for VETC-. Under Pazopanib a PPD of median PFS of 20 mo (SD: 8 mo) for VETC+ Vs 11 mo (SD: 7 mo) for VETC-. The expected gain of median PFS for of VETC+ cases, was 17 and 9 mo (SD: 12 and 11 mo), respectively in sunitinib and pazopanib treated cases. Conclusions: Our results confirmed the general adverse prognostic role of VETC in RCC, however this phenotype gave a substantial PFS gain for patients treated with TKI, similarly to what have been observed in HCC. VETC could be a new predictive bio-marker that allows the delivery of a personalized treatment: patients affected by RCC might directly benefit from a better selection of already approved drugs.

644 Background: The introduction of tyrosine kinase inhibitors (TKI) and recently immunotherapy has brought major survival benefits for metastatic renal cancer (mRCC) patients (pts). In Brazil, there is no approved 2nd line treatment for mRCC in the Public Health System (PHS). Our center is unique, because it provides care for both PHS and Private System (PrS) population, enabling us to make the comparison of overall survival (OS) of these pts. Methods: We retrospectively reviewed medical records of all mRCC pts treated with 1st line TKI at our service from 2007 to 2018. Categorial variables were compared by Fisher’s exact test and continuous by Mann–Whitney. Survival was estimated by Kaplan-Maier method, prognostic factors adjusted by Cox regression model. Results: 171 pts were eligible, 37 (21.6%) PHS and 134 (78.4%) PrS pts. Between the two groups, there was no differences in age, gender, number and sites of metastasis (mets). PHS pts had worst ECOG (≥2, in 35.1 vs 13.5%, p .007), a trend towards more poor IMDC risk (IMDC favorable 16.2 vs 26.6%, intermediate 51.4 vs 57%, poor 32.4 vs 16.4%, p.09), had less nephrectomies (73 vs 92.5%, p.008) and more non clear cell histology (32.4 vs 12.7%, p.01). Median lines of therapy were 1 for PHS vs 2 for PrS pts (p.03). Sunitinib was the 1st line agent for 91.9 vs 67.2%, and pazopanib 8.1 vs 29.9%, of the PHS and PrS pts, respectively. Median time from diagnosis of mets to treatment start was 2.29 vs 1.79 m (p.59). Median OS was 16.5 vs 26.5 m (p.0002) and progression free survival, 8.4 vs 11 m (p.01), for the PHS vs PrS. On multivariate analysis, after adjusting for factors that were present before the beginning of treatment and were statistically significant for OS in the univariate model, PHS pts still had higher risk of death (HR 1.85, IC 95 1.2-2.9, p.01), probably due to having received fewer lines of therapy (≥2 lines of therapy vs 1, HR 0.51, IC95 0.4-0.7, p .001). Conclusions: Brazilian PHS pts had significant worse OS compared to PrS pts, in part due to less access to drugs. Access to cancer drugs is a challenge worldwide, and in Brazil effort has to be done to change this reality.

Exon 11

In previous studies on localized GISTs, KIT exon 11 deletions and mutations involving codons 557/558 showed an adverse prognostic influence on recurrence-free survival. In the metastatic setting, there are limited data on how mutation type and codon location might contribute to progression-free survival (PFS) variability to first-line imatinib treatment. We analyzed the type and gene location of KIT and PDGFRA mutations for 206 patients from a GIST System database prospectively collected at an Italian reference center between January 2005 and September 2020. By describing the mutational landscape, we focused on clinicopathological characteristics according to the critical mutations and investigated the predictive role of type and gene location of the KIT exon 11 mutations in metastatic patients treated with first-line imatinib. Our data showed a predictive impact of KIT exon 11 pathogenic variant on PFS to imatinib treatment: patients with deletion or insertion/deletion (delins) in 557/558 codons had a shorter PFS (median PFS: 24 months) compared to the patients with a deletion in other codons, or duplication/insertion/SNV (median PFS: 43 and 49 months, respectively) (p < 0.001). These results reached an independent value in the multivariate model, which showed that the absence of exon 11 deletions or delins 557/558, the female gender, primitive tumor diameter (≤5 cm) and polymorphonuclear leucocytosis (>7.5 109/L) were significant prognostic factors for longer PFS. Analysis of the predictive role of PDGFRA PVs showed no significant results. Our results also confirm the aggressive biology of 557/558 deletions/delins in the metastatic setting and allow for prediction at the baseline which GIST patients would develop resistance to first-line imatinib treatment earlier.

The function of protein kinases is to transfer a γ-phosphate group from ATP to serine, threonine, or tyrosine residues. Many of these kinases are linked to the initiation and development of human cancer. The recent development of small molecule kinase inhibitors for the treatment of different types of cancer in clinical therapy has proven successful. Significantly, after the G-protein-coupled receptors, protein kinases are the second most active category of drug targets. Imatinib mesylate was the first tyrosine kinase inhibitor (TKI), approved for chronic myeloid leukemia (CML) treatment. Imatinib induces appropriate responses in ~60% of patients; with ~20% discontinuing therapy due to sensitivity, and ~20% developing drug resistance. The introduction of newer TKIs such as, nilotinib, dasatinib, bosutinib, and ponatinib has provided patients with multiple options. Such agents are more active, have specific profiles of side effects and are more likely to reach the necessary milestones. First-line treatment decisions must be focused on CML risk, patient preferences and comorbidities. Given the excellent result, half of the patients eventually fail to seek first-line treatment (due to discomfort or resistance), with many of them needing a third or even further therapy lines. In the present review, we will address the role of tyrosine kinase inhibitors in therapy for chronic myeloid leukemia.

Previous research involving epithelial ovarian cancer patients showed that, compared to germline BRCA (gBRCA) mutations, somatic BRCA (sBRCA) mutations present a similar positive impact with regard to overall survival (OS) and platinum and PARP (poly (ADP-ribose) polymerase) inhibitor sensitivity. Nevertheless, molecular testing in these studies did not include copy number variation (CNV) analyses of BRCA genes. The aim of this study was to explore the prognostic and predictive role of sBRCA mutations as compared to gBRCA mutations in patients who were also tested for CNVs. Among the 158 patients included in the study, 17.09% of patients carried a pathogenic or likely pathogenic gBRCA variant and 15.19% of patients presented pathogenetic or likely pathogenic sBRCA variants and/or CNVs. Overall, 81.6% of the patients included in this study were diagnosed with a serous histotype, and 77.2% were in advanced stages. Among women diagnosed in advanced stages, gBRCA patients showed better progression-free survival and OS as compared to sBRCA and wild-type patients, whereas sBRCA patients did not show any advantage in outcome as compared to wild-type patients. In this study, the introduction of CNV analyses increased the detection rate of sBRCA mutations, and the resulting classification among gBRCA, sBRCA and wild-type patients was able to properly stratify the prognosis of OC patients. Particularly, sBRCA mutation patients failed to show any outcome advantage as compared to wild-type patients.

Clinical Benefits

Abstract BACKGROUND While maximizing extent of resection (EOR) is associated with longer survival in lower-grade glioma (LGG) patients, the number of cases remains insufficient in determining a EOR threshold to elucidate the clinical benefits, especially in IDH-wild-type LGG patients. OBJECTIVE To identify the effects of EOR on the survival outcomes of IDH-wild-type LGG patients. METHODS IDH-wild-type LGG patients were retrospectively reviewed. The effect of EOR and other predictor variables on overall survival (OS) and progression-free survival (PFS) was analyzed using Cox regression models and the Kaplan-Meier method. RESULTS A total of 94 patients (median OS: 48.9 mo; median follow-up: 30.6 mo) were included in this study. In the multivariable Cox regression analysis, postoperative residual volume was associated with prolonged OS (HR = 2.238; 95% confidence interval [CI], 1.130-4.435; P = .021) and PFS (HR = 2.075; 95% CI, 1.113-3.869; P = .022). Thresholds at a minimum EOR of 97.0% or a maximum residue of 3.0 cm3 were necessary to impact OS positively. For the telomerase reverse transcriptase (TERT)p-wild-type group, such an association was absent. Significant differences in survival existed between the TERTp-wild-type and mutant patients who underwent relatively incomplete resections (residual ≥2.0 cm3 + TERTp wild type: median OS of 62.6 mo [95% CI: 39.7-85.5 mo]; residual ≥2.0 cm3 + TERTp mutant: median OS of 20.0 mo [95% CI:14.6-25.4 mo]). CONCLUSION Our results support the core role of maximal safe resection in the treatment of IDH-wild-type LGGs, especially for IDH-wild-type + TERTp-mutant LGGs. Importantly, the survival benefits of surgery could only be elucidated at a high EOR cut-off point.

Abstract Purpose European and French guidelines for ENSAT stage IV low tumor burden or indolent adrenocortical carcinoma (ACC) recommend combination of mitotane and locoregional treatments (LRT) in first-line. Nevertheless, the benefit of LRT combination with mitotane has never been evaluated in this selected group of patients. Methods A retrospective chart review was performed from 2003-2018 of patients with stage IV ACC with ≤2 tumoral organs who received mitotane in our center. Primary endpoint was the delay between mitotane initiation and first systemic chemotherapy. Secondary endpoints were progression-free survival (PFS) and overall survival (OS) from mitotane initiation. Adjusted analyses were performed on the main prognostic factors. Results Out of 79 included patients, 48 (61%) patients were female and median age at stage IVA diagnosis was 49.8 years (interquartile-range:38.8-60.0). Metastatic sites were mainly lungs (76%) and liver (48%). Fifty-eight (73%) patients received LRT including adrenal bed radiotherapy (14 patients, 18%), surgery (37 patients, 47%) and/or interventional radiology n(35,44%). Median time between mitotane initiation and first chemotherapy administration was 9 months (Interquartile-range:4-18). Median PFS1 (first tumor-progression) was 6.0 months (CI95%:4.5-8.6). Median OS was 46 months (CI95%:41-68). PFS1, PFS2 and OS were statistically longer in the mitotane plus LRT group compared to the mitotane-only group (Hazard ratio (HR)=0.39 (CI95%:0.22-0.68), HR=0.35 (CI95%:0.20-0.63) and HR=0.27 (CI95%:0.14-0.50) respectively). Ten (13%) patients achieved complete response, all from mitotane plus LRT group. Conclusion Our results endorse European and French guidelines for stage IV ACC with ≤2 tumor-organs and favor the combination of mitotane and LRT as first-line treatment. For the first time, a significant number of complete responses were observed. Prospective studies are expected to confirm these findings.

Patients with lung adenocarcinoma harboring common epidermal growth factor receptor (EGFR) mutations usually have a good response rate (RR) and longer progression-free survival (PFS) to EGFR tyrosine kinase inhibitors (TKIs). However, the treatment efficacy to uncommon EGFR mutations remains controversial. We, therefore, performed a retrospective study, screening 2958 patients. A total of 67 patients with lung adenocarcinoma harboring uncommon EGFR mutations were enrolled and 57 patients with stage IV diseases receiving a first-line EGFR TKI were included for further analyses. The patients were classified into 27 (47%) “a single sensitizing uncommon mutation”, 7 (12%) “multiple sensitizing mutations”, 5 (9%) “a sensitizing mutation and a resistant uncommon mutation”, and 18 (32%) “other resistant uncommon mutations”. No significant difference was noted in PFS or overall survival (OS) between groups. Patients receiving different first-line EGFR TKIs had similar PFS and OS. The elder patients had a significantly poorer performance status than the younger patients but a significantly longer PFS than the younger patients (median PFS: 10.5 vs. 5.5 months, p = 0.0320). In conclusion, this is the first study to identify that elderly patients with stage IV lung adenocarcinoma harboring uncommon EGFR mutation might have a longer PFS. Large-scale prospective studies are mandatory to prove our findings.

Neuroendocrine Carcinomas

IntroductionPatients with metastatic or locally advanced, non-resectable, grade 3 poorly differentiated gastroenteropancreatic (GEP) and lung neuroendocrine carcinomas (NECs) are usually treated with in first-line platinum compounds. There is no standard second-line treatment on progression. Accurate biomarkers are needed to facilitate diagnosis and prognostic assessment of patients with NEC.Methods and analysisThe SEcond-line therapy in NEuroendocrine CArcinomas (SENECA) study is a randomised, non-comparative, multicentre phase II trial designed to evaluate the efficacy and safety of folinic acid, 5-fluorouracil and irinotecan (FOLFIRI) or capecitabine plus temozolomide (CAPTEM) regimens after failure of first-line chemotherapy in patients with lung NEC and GEP-NEC. Secondary aims are to correlate the serum miRNA profile and primary mutational status of MEN1, DAXX, ATRX and RB-1 with prognosis and outcome and to investigate the prognostic and predictive role of the Ki-67 score and 18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) or 68Ga-PET/CT. The main eligibility criteria are age ≥18 years; metastatic or locally advanced, non-resectable, grade 3 lung or GEP-NECs; progression to first-line platinum-based chemotherapy. A Bryant and Day design taking into account treatment activity and toxicity was used to estimate the sample size. All analyses will be performed separately for each treatment group in the intention-to-treat population. A total of 112 patients (56/arm) will be randomly assigned (1:1) to receive FOLFIRI every 14 days or CAPTEM every 28 days until disease progression or unacceptable toxicity or for a maximum of 6 months. Patients undergo testing for specific biomarkers in primary tumour tissue and for miRNA in blood samples. MiRNA profiling will be performed in the first 20 patients who agree to participate in the biological substudy.Ethics and disseminationThe SENECA trial, supported by Istituto Scientifico Romagnolo per lo Studio e la Cura dei Tumori (IRST), was authorised by the locals Ethics Committee and the Italian Medicines Agency (AIFA). Results will be widely disseminated via peer-reviewed manuscripts, conference presentations and reports to relevant authorities.The study is currently open in Italy.Trail registration numberNCT03387592; Pre-results.
