Type and gene location of kit mutations predict progression-free survival to first-line imatinib in gastrointestinal stromal tumors: A look into the …
2021
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 inve…
Radiomics predicts survival of patients with advanced non-small cell lung cancer undergoing PD-1 blockade using Nivolumab
2019
Immune checkpoint blockade is an emerging anticancer strategy, and Nivolumab is a human mAb to PD-1 that is used in the treatment of a number of different malignancies, including non-small cell lung cancer (NSCLC), kidney cancer, urothelial carcinoma and melanoma. Although the use of Nivolumab prolongs survival in a number of patients, this treatment is hampered by high cost. Therefore, the identification of predictive markers of response to treatment in patients is required. In this context, PD-1/PDL1 blockade antitumor effects occur through the reactivation of a pre-existing immune response, and the efficacy of these effects is strictly associated with the presence of necrosis, hypoxia an…
The McCAVE Trial: Vanucizumab plus mFOLFOX‐6 Versus Bevacizumab plus mFOLFOX‐6 in Patients with Previously Untreated Metastatic Colorectal Carcinoma …
2019
Abstract Background Bevacizumab, a VEGF‐A inhibitor, in combination with chemotherapy, has proven to increase progression‐free survival (PFS) and overall survival in multiple lines of therapy of metastatic colorectal cancer (mCRC). The angiogenic factor angiopoetin‐2 (Ang‐2) is associated with poor prognosis in many cancers, including mCRC. Preclinical models demonstrate improved activity when inhibiting both VEGF‐A and Ang‐2, suggesting that the dual VEGF‐A and Ang‐2 blocker vanucizumab (RO5520985 or RG‐7221) may improve clinical outcomes. This phase II trial evaluated the efficacy of vanucizumab plus modified (m)FOLFOX‐6 (folinic acid (leucovorin), fluorouracil (5‐FU) and oxaliplatin) ver…
FAST: An international, multicenter, randomized, phase II trial of epirubicin, oxaliplatin, and capecitabine (EOX) with or without IMAB362, a first-i…
2016
LBA4001 Background: Claudin18.2 (CLDN18.2) is a tight junction protein expressed by several cancers including gastric and GEJ adenocarcinoma. IMAB362 is a chimeric monoclonal antibody that mediates specific killing of CLDN18.2-positive cancer cells by activation of immune effector mechanisms. IMAB362 has demonstrated single-agent activity and was safe and tolerable in patients (pts) with pretreated gastric cancer. Methods: Pts with advanced/recurrent gastric and GEJ cancer were centrally evaluated for CLDN18.2 expression by IHC (validated CLAUDETECT18.2 Kit). Eligible pts had a CLDN18.2 expression of ≥ 2+ in ≥ 40% tumor cells, an ECOG PS of 0–1 and were not eligible for trastuzumab. Pts we…
NK Cell Infiltrates and HLA Class I Expression in Primary HER2+ Breast Cancer Predict and Uncouple Pathological Response and Disease-free Survival
2019
Abstract Purpose: We investigated the value of tumor-infiltrating NK (TI-NK) cells and HLA class I tumor expression as biomarkers of response to neoadjuvant anti-HER2 antibody–based treatment in breast cancer. Experimental Design: TI-NK cells and HLA-I were determined by IHC in pretreatment tumor biopsies from two cohorts of patients with HER2-positive breast cancer [discovery cohort (n = 42) and validation cohort (n = 71)]. Tumor-infiltrating lymphocytes (TIL) were scored according to international guidelines. Biomarker association with pathologic complete response (pCR) and disease-free survival (DFS) was adjusted for prognostic factors. Gene set variation analysis was used for determinin…
Maintenance therapy with avelumab (MSB0010718C; anti-PD-L1) vs continuation of first-line chemotherapy in patients with unresectable, locally advance…

TPS4134Background: Programmed death-1 receptor ligand (PD-L1) is a key therapeutic target in the reactivation of the immune response against multiple cancers. Avelumab* is a fully human anti-PD-L1 ...
CanStem303C trial: A phase III study of napabucasin (BBI-608) in combination with 5-fluorouracil (5-FU), leucovorin, irinotecan (FOLFIRI) in adult pa…
2017
TPS3619 Background: Cancer stem cells are considered to be fundamentally important for resistance to therapy, recurrence and metastasis. Napabucasin is a first-in-class cancer stemness inhibitor in development identified by its ability to inhibit STAT3-driven gene transcription and spherogenesis of cancer stem cells (Li et al, PNAS 112(6):1839, 2015). Preclinically, napabucasin sensitizes cancer cells to chemotherapeutics, including 5-FU and irinotecan. Encouraging anticancer activity in advanced CRC was observed in a phase Ib/II (Bendell et al, GI ASCO 2017) study of 63 pts with disease control rate (DCR) of 93% (28/30) and overall response rate (ORR) of 33% (10/30) in FOLFIRI-naïve pts w…
Copy number variations inDCC/18q andERBB2/17q are associated with disease-free survival in microsatellite stable colon cancer
2017
We conducted a prospective study to assess the prognostic impact of selected copy number variations (CNVs) in stage II-III microsatellite stable (MSS) colon cancer. A total of 401 patients were included from 01/2004 to 01/2009. The CNVs in 8 selected target genes, DCC/18q, EGFR/7p, TP53/17p, BLK/8p, MYC/8q, APC/5q, ERBB2/17q, and STK6/20q, were detected using a quantitative multiplex polymerase chain reaction of short fluorescent fragment (QMPSF) method. The primary end-point was the impact of the CNVs on the 4-year disease-free survival (DFS). The recurrence rate at 4 years was 20.9%, corresponding to 14% stage II patients vs 31% stage III patients (p<0.0001). The 4-year DFS was significan…
Phase I multicenter, open-label study to establish the maximum tolerated dose (MTD) of trifluridine/tipiracil (TAS-102) and oxaliplatin combination i…
2018
816 Background: Preclinical evidence suggests improved efficacy when combining trifluridine/tipiracil with oxaliplatin compared to each monotherapy (Nukatsuka, 2015). The primary objective was to determine the MTD and the safety profile of the doublet among mCRC pts who have progressed after at least one prior line of treatment. Methods: Using a 3+3 design, eligible pts received escalating trifluridine/tipiracil doses from 25, 30 to 35 mg/m² bid, days 1–5 q14, together with a fixed dose of oxaliplatin 85 mg/m² (day 1). An intermediate cohort with a lower dose of oxaliplatin (65 mg/m²) plus 35 mg/m² of trifluridine/tipiracil was also tested. Results: Fifteen of 17 enrolled pts were evaluabl…
