    Kurzfassung: e19296 Background: Precision medicine has led to important changes in the treatment paradigm for patients with lung adenocarcinoma (LA) with mutations in EGFR or rearrangements of ALK or ROS1. The objective of this study is to describe the proportion of patients with LA who had access to molecular testing and targeted molecular therapy at an oncology referral center in Northeast Mexico. Methods: A retrospective study was performed with information gathered from electronic health records of the Hospital Universitario “Dr. José E. González” in Monterrey, Mexico from 2014 to 2019. Patients with LA were identified based on ICD-10 codes (C34) and diagnosis was confirmed with histopathological reports. Results: A total of 316 cases of lung cancer were identified, of which, 194 (64%) were LA, and of those, 117 (60%) had access to molecular testing. Mutations in EGFR were detected in 47%; 38% in men and 59% in women. Rearrangements in ALK were observed in 6.4%, whereas no alterations in ROS1 were seen. Access to molecular testing increased from 2014 to 2019, with a rate of 42% to 67%, respectively. Among patients that were candidates to receive targeted molecular therapy only 37% had access in 2014 versus 66% in 2019. Conclusions: The frequency of mutations in EGFR among our patients with LA showed a high discrepancy with previous studies conducted in countries with a predominantly white population. In Latin America, reports range from 14% to 34% in Argentina and Mexico, respectively. In our study, we identified a higher proportion of mutations in EGFR when compared to what previously reported; however, limited access to molecular testing may bias our results. Despite the advances in treatment for patients with LA, the availability of molecular testing and personalized treatment remains a challenge for developing countries.

    Kurzfassung: e16542 Background: The treatment landscape of advanced Renal Cell Carcinoma (aRCC) has changed over the last years with the incorporation of immune checkpoint blockers (IO) to tyrosine kinase inhibitors (TKI). Today there are available several options based on the combination of IO-IO and IO-TKI in the first line setting for advanced disease (R. J. Motzer et al. (2018); Rini et al. (2019); Choueiri et al. (2021) R. Motzer et al. (2021)). Herein we present an observational retrospective study of patients treated with a combo in the clinical practice in Spain. Purpose: Main Objective: To describe the survival outcomes of patients diagnosed with aRCC treated in the context of routine clinical practice in our center. Secondary Objectives: (1) To explore other efficacy endpoints of IO-IO or IO-TKI in the first line, (2) to compare efficacy endpoints and safety profile of IO-IO versus IO-TKI and (3) to describe the safety profile of combos. Methods: We enrolled 53 patients between February 12, 2019 and January 12, 2023 in the University Clinical Hospital of Santiago de Compostela. All patients signed an informed consent before enrolling in the study. Results: With a median follow-up of 11.93 months, median overall survival was not reached. We observed a median progression free survival (PFS) of 10 months, (95% CI 6.8-NA). Nine patients were treated with Cabozantinib-Nivolumab, 10 patients with Axitinib-Pembrolizumab, 33 patients with Ipilimumab-Nivolumab (IO-IO) and 1 with Lenvatinib-Pembrolizumab. All (12 patients) IMDC good risk patients were treated with IO-TKI combo, meanwhile intermediate and poor risk patients received IO-TKI (8 cases) and IO-IO (33 patients). Patterns of treatment response were as follow (% complete responses / % partial responses): IO-TKI 15/55%, IO-IO 6.5/26%. Eleven (55%) and 15 patients (47%) received a nephrectomy in IO-TKI and IO-IO groups, respectively. Regarding tumor histology, only 2 were non-clear cell carcinomas, both with a papillary histology. In the intermediate-poor risk groups there was a non statistically significant trend towards a better overall survival favoring IO-TKI regimens (HR 1.84, 95% CI 0.65 - 5.20). Reported grade 3-4 adverse events were as follow: in IO-TKI group diarrhea (11%), hepatitis (11%) and bowel perforation (1 case); in IO-IO group were nephritis (11%), pneumonitis (11%), 1 case of tumor lysis syndrome and one of myocarditis. Conclusions: Combos of IO-IO & IO-TKI have increased overall response rate and survival in patients with aRCC. There are no statistically significant OS differences between IO-IO & IO-TKI. Immediate or delayed nephrectomy seem safe in selected patients. Together with clinical aspects, clinical trial availability & drug regulatory status determine the selection of combination therapies.

    Kurzfassung: The existence of patients with multiple myeloma (MM) and light-chain (AL) amyloidosis who present with a monoclonal gammopathy of undetermined significance (MGUS)–like phenotype has been hypothesized, but methods to identify this subgroup are not standardized and its clinical significance is not properly validated. PATIENTS AND METHODS An algorithm to identify patients having MGUS-like phenotype was developed on the basis of the percentages of total bone marrow (BM) plasma cells (PC) and of clonal PC within the BM PC compartment, determined at diagnosis using flow cytometry in 548 patients with MGUS and 2,011 patients with active MM. The clinical significance of the algorithm was tested and validated in 488 patients with smoldering MM, 3,870 patients with active MM and 211 patients with AL amyloidosis. RESULTS Patients with smoldering MM with MGUS-like phenotype showed significantly lower rates of disease progression (4.5% and 0% at 2 years in two independent series). There were no statistically significant differences in time to progression between treatment versus observation in these patients. In active newly diagnosed MM, MGUS-like phenotype retained independent prognostic value in multivariate analyses of progression-free survival (PFS; hazard ratio [HR], 0.49; P = .001) and overall survival (OS; HR, 0.56; P = .039), together with International Staging System, lactate dehydrogenase, cytogenetic risk, transplant eligibility, and complete remission status. Transplant-eligible patients with active MM with MGUS-like phenotype showed PFS and OS rates at 5 years of 79% and 96%, respectively. In this subgroup, there were no differences in PFS and OS according to complete remission and measurable residual disease status. Application of the algorithm in two independent series of patients with AL predicted for different survival. CONCLUSION We developed an open-access algorithm for the identification of MGUS-like patients with distinct clinical outcomes. This phenotypic classification could become part of the diagnostic workup of MM and AL amyloidosis.

    Kurzfassung: 9503 Background: There is no established standard of care for unresectable locally advanced or metastatic CSCC. UV-induced DNA damage causes hypermutation in most CSCCs. Therefore, these tumors may be responsive to PD-1 checkpoint blockade. In the dose escalation portion of the phase 1 study of REGN2810, a durable (19 + months) radiologic complete response was observed in a patient (pt) with metastatic CSCC (ASCO 2015, #3024). Methods: ECs enrolled pts with distantly metastatic (EC 7) and locally advanced (EC 8) CSCC. All patients received 3 mg/kg REGN2810 by intravenous infusion over 30 minutes every 2 weeks for up to 48 weeks. Research biopsies were performed at baseline and Day 29 (and at progression, if possible). Tumor measurements were performed every 8 weeks according to RECIST 1.1 to determine overall response rate (ORR). Data cutoff date was 31 Jan 2017. Results: 26 pts were enrolled (10 in EC 7 and 16 in EC 8): median age, 72.5 y (range, 56-88y); median PS 1 (range, 0 – 1); 21M:5F; median number of prior systemic therapy regimens, 1 (range, 0 – 2). Median exposure to REGN2810 was 7 doses (range, 1-22). The most common treatment-related adverse event of any grade was fatigue (19.2%). Each of the following ≥ Grade 3 related AEs occurred once: AST elevation, ALT elevation, arthralgia, and rash. ORR (PR + CR, including unconfirmed) and disease control rate (ORR+SD) were 52% (12/23; 4uPR, 5 PR, 2CR, 1 uCR) and 70% (16/23, including 4SD), respectively. Three patients are not yet evaluable. Median PFS and OS have not been reached, and only one patient has experienced PD during REGN2810 treatment after initial response. Correlative studies are in process, including PD-L1 status and whole exome tumor DNA sequencing. Conclusions: REGN2810 is well tolerated and produces antitumor activity in patients with advanced CSCC. A pivotal trial of REGN2810 for patients with advanced CSCC is enrolling patients (NCT02760498). Clinical trial information: NCT02383212.

    Kurzfassung: e15561 Background: Comorbidity as a prognostic marker has been reported in several solid tumors. We examined whether co-morbidity indices predict survival in Veterans with metastatic renal cell carcinoma (RCC) who were treated with signal transduction inhibitors. Methods: In an IRB-approved protocol, we reviewed the records of patients (Pts) diagnosed with RCC at a VA Medical Center from 1/1/2000 to 12/31/2011. Age, ECOG Performance Status (ECOG PS), Hemoglobin (Hgb), Albumin (Alb), Corrected Calcium (CCa), history of Nephrectomy, and histology (clear cell (CC) vs. non clear cell (NCC)) were abstracted. Co-morbidity was assessed with Charlson Comorbidity Index (CCI), and the Kaplan-Feinstein Index (KFI). We developed a survival model with age, ECOG PS, Hgb, Alb, CCa, history of nephrectomy, and histology. Co-morbidity indices were tested by determining if they were independent predictors of survival after inclusion in this model. Cox regression analyses were performed with SAS V9.2. Results: There were 24 Pts;6 (25%) are alive. The Median (M) age when seen at VA was 64 years (54-85). The M Hgb level was 12.1g/dL (6.7-16.5), Alb was 4.1g/dL (2.8-5.0), and CCa was 9.19mg/dL (7.9-12.5). The M CCI was 4.2 (1.4-12.0) and KFI was 2.0 (1-3). The M Survival was 823 days (24-3482). 17(68%) pts had clear cell carcinoma and 18(72%) had nephrectomies Median ECOG PS was one range(0-4). The median number of treatments was 2, range 1-7. Results of univariate analyses with co-morbidity indices were significant for age (p 〈 ,029) and history of nephrectomy p 〈 .068). There were no multivariate predictors of survival. Conclusions: In the univariate analysis, ECOG PS as well as Nephrectomy status were significant predictors for M survival. CCI and KFI did not predict M survival. In distinction to other solid tumor histologies where chemotherapy is used, KFI and CCI in RCC may not be associated with overall survival due to either RCC histology or use of signal transduction inhibitors as treatment. Confirmatory studies should be done in larger populations. This was supported by the New Jersey Commission for Cancer Research.

    Kurzfassung: e19606 Background: Understanding determinants of survival remains a challenge in patients(pts) with advanced cancer. Prognostic factors of interest include pts rating of their own performance status, and patient responses from the EQ-5D. Methods: This prospective study was approved by the VA New Jersey HCS IRB. Pts with metastatic cancer whose cancer had already been treated with standard or experimental chemotherapy with KPS 〈 80%, or who did not wish to receive systemic chemotherapy, were recruited in a specified manner. At entry, Karnofsky performance status (KPS) was estimated, pts rated their own KPS, and answered a modified version of the EQ-5D. Cox regression survival analyses were performed. Results: Of 242 pts enrolled, 237 pts were analyzable. Median (M) age was 67 years (range 44-88), with 56% white, 41% black and 3% other; lung (26%) and prostate (18%) were the 2 most common primary sites and M KPS was 60% (range 30-100%). The majority (97%) of pts have died, with M survival of 95 days, range 4-2032 days. Higher KPS is associated with decreased risk of death (p 〈 .0001). Both patient KPS (p 〈 0.0319) and physician rated KPS were predictive of survival (p 〈 0.004). Discrepancy between physician and pt KPS was noted, with upstaging by pts 48%, same for 27%, and downstaging in 25%, with no effect on survival. Physician KPS was a better predictor than pt KPS at each level. The EQ-5D pain item showed an increased risk of death with increasing pain (p 〈 0.0001). The pain item was associated with KPS: pts with no pain had average KPS 75; moderate pain average KPS 63; extreme pain average KPS 48. The patient’s EQ-5D health rating was positively correlated with survival (p=0.0054), and with KPS (r=0.36). The other items in the EQ-5D did not predict survival. When all the factors (physician KPS, pt KPS, pain, health) were incorporated into a Cox model, only physician KPS was statistically significant (p=0.0033). Conclusions: Pts ratings of health and pain are significantly associated with KPS. Pts have a more positive outlook on their performance status. Physician KPS may be a better predictor because physicians have a wider frame of reference. Physician KPS can contribute to determination of hospice eligibility. Supported by VA HSRD IIR 2-103

    Kurzfassung: e15575 Background: Angiogenesis is essential to tumor growth, invasion, and metastasis in EOC. The aim of this study was to identify angiogenic biomarkers to predict response to P, a potent and selective multi-targeted receptor tyrosine kinase inhibitor of VEGFR-1, VEGFR-2, VEGFR-3, PDGFR-a/β, and c-kit, in a clinical phase II trial. Methods: We analyzed a series of 20 out of 25 women enrolled in a GEICO Phase II trial that studied the Clinical Benefit Rate (CBR) of P in platinum-resistant EOC, PPC and FTC (results will be presented in an additional abstract). Formalin-fixed, paraffin-embedded tumors at diagnosis were evaluated for the microvessel density (MVD) by using CD31 immunostaining and the Image Pro-Plus 7.0 Image Analysis System (Media-Cybernetics). In addition, several angiogenic factors were evaluated by means of immunohistochemistry (IHC) on tissue arrays sections, and quantitative real-time PCR (qRT-PCR) using the Human Angiogenesis Arrays (Applied Biosystems). Serum samples were also collected at different moments of the treatment schedule and a panel of 14 citokines and growth factors were evaluated using the Luminex technology (Millipore). Results: Fifteen (75%) of the tumors were high grade serous EOC. Eight patients (40%) showed a CBR on treatment.MVD analysis, (number of vessels/mm 2 ) was 2025 (835-3242) and 2410 (1449-3543) in patients with and without CBR respectively (p=0.278). IHC showed very low expression of angiogenesis-related factors including VEGF and VEGFRs, PDGF and PDGFRs, HIF and pAKT. Expression analysis by qRT-PCR and serum levels of cytokines and growth factors revealed no statistical differences between patients with and without CBR. Conclusions: No predictive biomarkers of CBR to P in platinum-resistant EOC could be identified in a population of patients with low expression level of angiogenic factors at diagnosis.

    Kurzfassung: e14124 Background: This study is to analyze demographics and patterns of care for veterans with colorectal cancer. Methods: In an IRB approved protocol, we reviewed the records of pts diagnosed with colorectal adenocarcinoma at a VA Medical Center from 1/1/2003 to 12/31/2007. Demographics including age, sex, ECOG PS, stage, grade, site, CEA, hemoglobin (HGB), liver function tests at diagnosis, treatments and cause of death were reviewed. Results: There were 176 pts with colorectal ca with 112 colon (C) and 64 rectal ca (R) pts. One was a woman and the rest were men. The median age at diagnosis was 71 years (range 45-90). Median survival was 1157 days (5-3256). 95 (54%) pts were dead at this analysis. Median ECOG PS is 0. 160 pts had ECOG PS 0-2, 16pts ECOG 3-4. 4 (2.4%). 4 (2.4%) pts has stage 0, 51 (30.7%) stage 1, 42 (25.3%) stage 2, 35 (21.1%) stage 3, and 34 (20.5%) stage 4. 6 (3.7%) has grade 1, 111 (68.1%) grade 2, and 46 (28.2%) grade 3. Median CEA at diagnosis was 2.9 (0-3117), HGB 12.4 g/dl (6.6-16.7), albumin g/dl 3.98(1.7-4.7), AST 23 units/L (4-107), ALT 20 units/L (8-107), ALKP 77 units/L (37-352), Total bilirubin 0.7 mg/dl (0.1-4.5). 29 pts has liver metastasis at diagnosis. 147 pts (85.4%) received surgical resection. Total 43 pts had adjuvant treatment. 17 pts with rectal cancer had neoadjuvant chemoradiation . 7 pts had down staging and 3 pts had no residual disease after neoadjuvant chemoradiatoion. Total 14 pts had recurrence. 23 pts received palliative chemotherapy when metastatic. 54 of 95 pts (57%) died from cancer progression. Conclusions: This study provides a basis for understanding the epidemiology of colorectal cancer patient in a VA medical center.
