    Abstract: PURPOSE: This phase III study was designed to demonstrate equivalence in survival of oral uracil/tegafur (UFT) and oral leucovorin (LV) to conventional intravenous (IV) fluorouracil (5-FU) and LV in previously untreated metastatic colorectal carcinoma. Safety was also compared. PATIENTS AND METHODS: Eight hundred sixteen patients were randomized to receive either UFT (300 mg/m 2 /d) and LV (75 or 90 mg/d) for 28 days every 35 days or IV bolus 5-FU (425 mg/m 2 /d) and LV (20 mg/m 2 /d) for 5 days every 28 days. RESULTS: UFT/LV produced survival comparable to the IV 5-FU/LV regimen. Median survival was 12.4 months (95% confidence interval [CI], 11.2 to 13.6 months) with UFT/LV and 13.4 months (95% CI, 11.6 to 15.4 months) with 5-FU/LV (P = .630). The hazard ratio for survival was 0.964 (95.6% CI, 0.826 to 1.125), supporting equivalent survival. The overall response rate did not differ between treatment arms (UFT/LV, 11.7%; 5-FU/LV, 14.5%; P = .232). Median time to progression favored 5-FU/LV (UFT/LV, 3.5 months; 5-FU/LV, 3.8 months; P = .011), but tumor assessment schedules differed between arms. UFT/LV significantly improved safety compared with 5-FU/LV. Diarrhea, nausea and vomiting, and stomatitis and mucositis were significantly less frequent with UFT/LV, as was myelosuppression. Patients treated with UFT/LV had fewer episodes of febrile neutropenia (P 〈 .001) and documented infections (P 〈 .05). Increased bilirubin, without other liver function abnormalities, was observed more often with UFT/LV (P 〈 .001). Concomitant medications were more frequent with 5-FU/LV, including use of antibiotics, growth factors, and antiemetics. CONCLUSION: UFT/LV provided a safer, more convenient oral alternative to a standard bolus IV 5-FU/LV regimen for metastatic colorectal cancer while producing equivalent survival.

    Abstract: Vitamin D (VitD) deficiency is common in patients with hematologic malignancies undergoing allogeneic transplantation (alloSCT), but its prognostic relevance is unclear. Patients and Methods The impact of pretransplant VitD status on overall survival, relapse mortality, and nonrelapse mortality was investigated retrospectively in a cohort of 492 patients undergoing alloSCT at our center from 2002 to 2013. VitD deficiency was defined as a serum level of 25-hydroxyvitamin D3 〈 20 ng/mL (equivalent to 〈 50 nM) before alloSCT and was assessed using accredited laboratory methods and a standard chemiluminescent immunoassay. Results were validated in an independent cohort of 398 patients diagnosed with myeloid malignancies. Results A total of 396 (80%) and 348 (87%) patients had VitD deficiency before alloSCT in the training and validation cohort, respectively. In the training cohort, VitD deficiency was significantly associated with inferior overall survival (hazard ratio [HR], 1.78; P = .007) in multivariable analysis. This was due to a higher risk of relapse (HR, 1.96; P = .006) rather than nonrelapse mortality. A significant association of pretransplant VitD deficiency with higher relapse rates was observed only in patients diagnosed with myeloid (HR, 2.55; P = .014) but not with lymphatic diseases (HR, 1.60; P = .147). A similar impact of pretransplant VitD deficiency on relapse risk in myeloid diseases was also observed in an independent patient cohort (HR, 2.60; P = .017). Validation of the effect of VitD deficiency on relapse in patients with myeloid malignancies was successful. Conclusion Pretransplant VitD deficiency was associated with a higher risk of relapse in patients allografted for myeloid malignancies. Prospective studies on VitD status and correction of VitD deficiency in the setting of alloSCT are highly warranted.

    Abstract: 9506 Background: Medulloblastoma is the most common malignant brain tumor and a significant cause of cancer mortality in children. Despite considerable therapeutic advances, prognosis remains poor, with a five-year-survival rate of about 60% emphasizing the urgent need for markers to allow for a more accurate tailoring of treatment intensity. Methods: We performed genome-wide analysis of DNA-copy number in 112 medulloblastomas using array-CGH. All patients had received craniospinal irradiation after surgery. Standard adjuvant chemotherapy with lomustine, cisplatin and vincristine or a regimen with equal potency had been administered to 73 patients. To identify novel prognostic markers, DNA copy number information was correlated with survival data using log rank and chi-square tests. For selected candidate genes identified by array-CGH, mRNA and protein expression were analyzed by real-time quantitative PCR, and immunohistochemically on tissue microarrays consisting of medulloblastomas from 189 patients. Results: Copy-number gains of chromosomes 6 and 17q, high-level amplifications of MYC and MYCN, and loss of 9p21.3 (CDKN2A locus) were identified as significant adverse prognostic markers; monosomy 6 was associated with good prognosis. Monosomy 6 and gain of 17q were mutually exclusive, whereas trisomy 6 almost always occurred in conjunction with 17q gain. Tumors with trisomy 6 and 17q gains exhibit strong up-regulation of MAP3K7 (chr. 6) and NLK (17q) mRNA, two key-enzymes of the non-canonical calcium-dependent Wnt-signaling pathway. Furthermore, this subgroup exclusively shows high mRNA-expression of several cancer-retina antigens (e.g. GNGT1, GNGT2, PDE6, RCV1, RDS and NRL). Tumors with monosomy 6, in contrast, display highly activated canonical Wnt signaling as indicated by nuclear protein expression of beta-catenin. Conclusions: We propose a model for the molecular risk stratification of medulloblastoma comprising five risk groups with significantly different survival using copy-number status of MYC, MYCN, and chromosomes 6 and 17q. Furthermore, we give evidence for a role of noncanonical calcium-dependent Wnt-signalling in medulloblastoma metastasis in a subset of tumors. Cancer-retina antigens could be used to facilitate the diagnosis and follow-up of this molecular subgroup. No significant financial relationships to disclose.

    Abstract: This review describes the early clinical development of uracil-ftorafur (UFT), an oral fluoropyrimidine, designed in 1978 by adding uracil to ftorafur. The review focuses on the treatment of colorectal cancer and summarizes the Japanese experience and the phase I and II trials performed in the United States and Europe. RESULTS Clinical trials of UFT published in the Western world have included 581 patients with colorectal cancer. UFT has been administered in these trials as a single agent or biomodulated by leucovorin (LV). UFT was administered daily in split doses for periods that ranged from 14 to 28 days. The activity of oral UFT in large-bowel cancer when administered with oral LV (approximately 50 mg/dose) has resulted in objective response rates of approximately 40%. Response rates of approximately 25% (range, 17% to 39%) were reported when UFT was administered as a single agent or with lower doses of LV. The highest dose-intensities of UFT are achieved with 28-day schedules of administration. The maximum-tolerated dose (MTD) of UFT with this schedule, when administered concomitantly with oral LV 150 mg daily, is 300 mg/m2 daily. The dose-limiting toxicity (DLT) of UFT has generally been diarrhea. Other commonly described toxicities include nausea and vomiting, fatigue, and stomatitis. Myelosuppression occurs infrequently. Typically, hand-foot syndrome and neurologic toxicity are lacking. CONCLUSION UFT is a fluoropyrimidine active in colorectal cancer. The oral route of administration and improved safety profile represent important advantages over both conventional and infusional fluorouracil (5-FU) regimens.

    Abstract: We conducted a phase II study to determine the response and toxicity of docetaxel (Taxotere; Rhône-Poulenc Rorer Pharmaceuticals, Inc, Collegeville, PA) in chemotherapy-naive patients with advanced non-small-cell lung cancer. PATIENTS AND METHODS We treated 41 chemotherapy-naive patients who had stage IIIb or IV non-small-cell lung cancer with 100 mg/m2 of docetaxel intravenously over 1 hour every 3 weeks. Responses were assessed after every one to two treatment courses. Responses of 39 of 41 patients were assessable. The patient's median age was 63 years; 90% of patients had a Zubrod performance status of 0 or 1. The predominant histology was adenocarcinoma (54%), and 90% of patients had stage IV disease. RESULTS Thirteen patients (33%) achieved a partial response to treatment, and the median response duration was 14 weeks. Grade 3 or 4 neutropenia occurred in 97% of patient; this was usually of brief duration and was associated with serious infection in 17% of patients. Other acute toxic effects included easily treated hypersensitivity reactions (36% of patients) and dermatitis (74%). We also observed fluid retention (with peripheral edema or pleural effusion or both) in 54% of patients. This was a cumulative side effect that generally occurred late in treatment. CONCLUSION Docetaxel administered at 100 mg/m2 intravenously every 3 weeks has significant activity against non-small-cell lung cancer, with a 33% major response rate. Primary toxicities were neutropenia, hypersensitivity, and fluid retention.

    Abstract: Medulloblastoma is the most common malignant brain tumor in children. Despite multimodal aggressive treatment, nearly half of the patients die as a result of this tumor. Identification of molecular markers for prognosis and development of novel pathogenesis-based therapies depends crucially on a better understanding of medulloblastoma pathomechanisms. Patients and Methods We performed genome-wide analysis of DNA copy number imbalances in 47 medulloblastomas using comparative genomic hybridization to large insert DNA microarrays (matrix-CGH). The expression of selected candidate genes identified by matrix-CGH was analyzed immunohistochemically on tissue microarrays representing medulloblastomas from 189 clinically well-documented patients. To identify novel prognostic markers, genomic findings and protein expression data were correlated to patient survival. Results Matrix-CGH analysis revealed frequent DNA copy number alterations of several novel candidate regions. Among these, gains at 17q23.2-qter (P 〈 .01) and losses at 17p13.1 to 17p13.3 (P = .04) were significantly correlated to poor prognosis. Within 17q23.2-qter and 7q21.2, two of the most frequently gained chromosomal regions, confined amplicons were identified that contained the PPM1D and CDK6 genes, respectively. Immunohistochemistry revealed strong expression of PPM1D in 148 (88%) of 168 and CDK6 in 50 (30%) of 169 medulloblastomas. Overexpression of CDK6 correlated significantly with poor prognosis (P 〈 .01) and represented an independent prognostic marker of overall survival on multivariate analysis (P = .02). Conclusion We identified CDK6 as a novel molecular marker that can be determined by immunohistochemistry on routinely processed tissue specimens and may facilitate the prognostic assessment of medulloblastoma patients. Furthermore, increased protein-levels of PPM1D and CDK6 may link the TP53 and RB1 tumor suppressor pathways to medulloblastoma pathomechanisms.

    Abstract: Bortezomib has become a cornerstone in the treatment of AL amyloidosis. In this study, we addressed the prognostic impact of cytogenetic aberrations for bortezomib-treated patients. Patients and Methods We analyzed a consecutive series of 101 patients with AL amyloidosis treated with bortezomib-dexamethasone as first-line treatment by interphase fluorescence in situ hybridization (iFISH). Patients were ineligible for high-dose chemotherapy, which would put them at risk for cardiac or renal failure, and thus represented a poor-risk group. Results Presence of t(11;14), versus its absence, was associated with inferior hematologic event-free survival (median, 3.4 v 8.8 months, respectively; P = .002), overall survival (median, 8.7 v 40.7 months, respectively; P = .05), and remission rate (≥ very good partial remission; 23% v 47%, respectively; P = .02). In multivariable Cox regression models incorporating established hematologic and clinical risk factors, t(11;14) was an independent adverse prognostic marker for hematologic event-free survival (hazard ratio, 2.94; 95% CI, 1.37 to 6.25; P = .006) and overall survival (hazard ratio, 3.13; 95% CI, 1.16 to 8.33; P = .03), but not for remission (≥ very good partial remission). Markedly, the multiple myeloma high-risk iFISH aberrations t(4;14), t(14;16), del(17p), and gain of 1q21 conferred no adverse prognosis in this bortezomib-dexamethasone–treated group. After backward variable selection, the final multivariable model was validated in a consecutive series of 32 patients treated with bortezomib, dexamethasone, and cyclophosphamide. Conclusion iFISH results are important independent prognostic factors in AL amyloidosis. In contrast to our recently published results with melphalan and dexamethasone standard therapy, bortezomib is less beneficial to patients harboring t(11;14), whereas it effectively alleviates the poor prognosis inherent to high-risk aberrations. Given the discrepant response to different treatment modalities, iFISH may help to guide therapeutic choices in these poor-risk patients requiring rapid hematologic response.

    Abstract: 4123 Background: LAG-3 is an immune checkpoint present on NK cells, activated T cells and myeloid cells that inhibit T cell responses. Recent evidence demonstrating the safety and efficacy of LAG-3 inhibition has increased interest in this pathway for the treatment of multiple malignancies but the role in NEN is unclear. We present results from correlative peripheral blood mass cytometry (CyTOF) performed in a phase 2 trial (NCT03728361) of the combination of NIVO and TMZ in pts with advanced NEN. Methods: Patients (pts) with progressive NEN of any grade or primary location and any line of therapy were eligible. Small cell lung cancer was excluded. Clinical results from NCT03728361 will be presented in a separate abstract. Study treatment consisted of NIVO 480 mg IV every 4 weeks and TMZ 150 mg/m2 for 5 consecutive days out of a 28-day cycle. Peripheral blood mononuclear cells (PBMCs) were available from 16 out of 28 patients at screening (baseline) and cycle 1, day 15 (C1D15) and analyzed via CyTOF. Antibody labelling was performed using a 37 marker Maxpar Direct Immune Profiling Assay (Fluidigm). Immune cell populations were compared using two sample t-tests between pts with partial response (PR) and non-partial response (non-PR). Results: At screening, no differences were observed in PD-1, TIM3, or KLRG1 positive T-cell populations between pts with PR or non-PR. Patients with a PR had a significantly lower % of LAG-3 expressing T cells (p=0.029). There was a trend towards a lower % CD8+LAG-3+ T cells in pts with PR (p=0.086). At C1D15: The % of CD8+ LAG-3+ T cells were significantly higher in PRs vs. non-PR (p = 0.015). In matched samples comparing T cell populations at screening to C1D15, LAG-3+ CD8+ T cells increased significantly in PRs when compared to non-PRs (p=0.021). Conclusions: The % of LAG-3+ T cell population at baseline associates with non-response to TMZ/NIVO in NENs. Among responders, there was a significant increase in CD8+ LAG-3+ T cells by Day 15 compared to baseline indicating a potential mechanism of immune escape and eventual resistance. Clinical trial information: NCT03728361. [Table: see text]
