Pembrolizumab in First-line Gastric Cancer: Win, Lose, or Draw?
2020
IMPORTANCE: Safe and effective therapies for untreated, advanced gastric/gastroesophageal junction (G/GEJ) cancer remain an unmet need. OBJECTIVE: To evaluate the antitumor activity of pembrolizumab, pembrolizumab plus chemotherapy, or chemotherapy alone in patients with untreated, advanced G/GEJ cancer with programmed cell death ligand 1 (PD-L1) combined positive score (CPS) of 1 or greater. DESIGN, SETTING, AND PARTICIPANTS: The phase 3 KEYNOTE-062 randomized, controlled, partially blinded interventional trial enrolled 763 patients with untreated, locally advanced/unresectable or metastatic G/GEJ cancer with PD-L1 CPS of 1 or greater from 200 centers in 29 countries between September 18, …
Pegylated Liposomal Doxorubicin with Vinorelbine in Metastatic Breast Carcinoma
2002
A multicenter phase I-II trial was carried out with the aim of identifying the dose-limiting toxicity and the maximum tolerated dose of vinorelbine (VNR) in combination with pegylated liposomal doxorubicin at a dose of 20 mg/m<sup>2</sup> every 15 days in patients with metastatic breast carcinoma. In the phase I part of the trial, VNR was given at a dose of 20 mg/m<sup>2</sup> every 15 days to a group of 3 patients. In absence of unacceptable toxicity, VNR was escalated to 25, 30, and 35 mg/m<sup>2</sup> for subsequent groups of 3 patients, until the dose-limiting toxicity was reached. No case of palmar-plantar erythrodysesthesia was recorded in these pat…
First-line (1L) nivolumab (NIVO) plus chemotherapy (chemo) versus chemo in advanced gastric cancer/gastroesophageal junction cancer/esophageal adenoc…
2021
4002 Background: CheckMate 649 is the largest randomized, global phase 3 study of 1L programmed death (PD)-1 inhibitor–based therapy in GC/GEJC/EAC. 1L NIVO + chemo demonstrated superior overall survival (OS) vs chemo, with progression-free survival (PFS) benefit and an acceptable safety profile in pts whose tumors expressed PD-ligand (L)1 at combined positive score (CPS) ≥ 5 and ≥ 1, and in all randomized pts (Moehler et al. Ann Oncol 2020). We report additional data for all randomized pts. Methods: Eligible pts had previously untreated, unresectable advanced or metastatic GC/GEJC/EAC. Known HER2-positive pts were excluded. Pts were randomized to receive NIVO (360 mg Q3W or 240 mg Q2W) + …
Phase II Trial of Preoperative Irinotecan–Cisplatin Followed by Concurrent Irinotecan–Cisplatin and Radiotherapy for Resectable Locally Advanced Gast…
2009
Purpose To determine in a Phase II trial whether preoperative irinotecan–cisplatin (IC) followed by concurrent IC therapy and radiotherapy (IC/RT) improved outcome in patients with resectable, locally advanced gastric adenocarcinoma (GC) or esophagogastric junction cancer (EGJC). Patients and Methods Patients with resectable Stage II–IV, M0 GC or EGJC made up the study population. The primary endpoint was pathologic complete response (pCR). Two courses of IC (irinotecan, 65mg/m 2 ; cisplatin, 30mg/m 2 on Days 1 and 8 every 21 days) were given. Patients without progression then received IC/RT, consisting of daily radiotherapy (45Gy) with concurrent IC (irinotecan, 65mg/m 2 ; cisplatin, 30mg/…
Highlights of the EORTC St. Gallen International Expert Consensus on the primary therapy of gastric, gastroesophageal and oesophageal cancer - differ…
2012
The 1st St. Gallen EORTC Gastrointestinal Cancer Conference 2012 Expert Panel clearly differentiated treatment and staging recommendations for the various gastroesophageal cancers. For locally advanced gastric cancer (>= PT3N+), the preferred treatment modality was pre- and postoperative chemotherapy. The majority of panel members would also treat T2N+ or even T2N0 tumours with a similar approach mainly because pretherapeutic staging was considered highly unreliable. It was agreed that adenocarcinoma of the gastroesophageal junction (AEG) is classified best according to Siewert et al. Preoperative radiochemotherapy (RCT) is the preferred treatment for AEG type I and II tumours. For AEG type…
DNA ploidy and S-phase fraction, but not p53 or NM23-H1 expression, predict outcome in colorectal cancer patients. Result of a 5-year prospective stu…
2002
Purpose: The aim of this study was to determine TP53 and NM23-H1 immunoreactivity, DNA ploidy, and S-phase fraction (SPF) in a series of 160 patients undergoing resective surgery for primary operable colorectal cancer (CRC) and to establish whether these alterations have any clinical value in predicting CRC patients' prognosis. Methods: TP53 and NM23-H1 expressions were evaluated on paraffin-embedded tissue by immunohistochemistry and DNA-ploidy and SPF on frozen tissue by flow-cytometric analysis. Results: The median follow-up time in our study group was 71 months (range 34-115 months). P53 protein expression was associated with distal tumors (P < 0.05) and DNA aneuploid tumors (P < …
Prognostic role of immune checkpoint-related genes in resectable lung adenocarcinomas.
2014
11085 Background: Immune checkpoints blockade has demonstrated promising clinical results in NSCLC patients. In this study we have investigated the prognostic role of immune checkpoint markers (CTLA4, PD1 and PDL1) in resectable lung adenocarcinoma (ADC). Methods: RNA was isolated from fresh-frozen lung specimens (tumor and normal lung) from resectable ADC patients (n=92). RT-PCR was performed to analyze the expression of CTLA4, PD1 and PDL1 by the use of hydrolysis probes. Relative gene expression was assessed by Pfaffl formula and normalized by CDKN1B and ACTB as endogenous genes (selected by geNorm algorithm). Statistical analyses were considered significant at p<0.05. Results: Patient’s…
HER2 status in advanced gastric carcinoma: A retrospective multicentric analysis from Sicily.
2013
According to the ToGA trial, HER2 has been shown to be predictive for the success of treatment with trastuzumab in advanced gastric cancer (AGC). A number of studies have analyzed HER-2/neu overexpression in gastric carcinoma and identified the rate of HER2 positivity to be markedly varied. To date, the prevalence of HER2 overexpression in Sicilian people with AGC is unknown. Therefore, in the present study, a retrospective immunohistochemical analysis of HER2 was performed in a cohort of 304 AGC samples that were obtained from the archives of 10 Sicilian anatomopathological diagnostic units in order to verify the positive rate of HER2-positive cases. Furthermore, the characteristics of his…
Abstract CT282: KEYNOTE-975: A randomized, double-blind, placebo-controlled phase 3 trial of pembrolizumab vs placebo in participants with esophageal…
2020
Abstract Background: For patients with unresectable esophageal cancer (EC), definitive chemoradiotherapy (dCRT) is a standard treatment option. Platinum plus fluoropyrimidine-based regimens are comparable in dCRT and are considered standard options; however, overall survival (OS) is still poor, indicating a need for more effective therapies. The programmed cell death 1 inhibitor pembrolizumab showed promising response as third- and second-line monotherapy in patients with advanced, unresectable EC in the KEYNOTE-180 and KEYNOTE-181 studies, respectively. In the phase 3 KEYNOTE-181 trial, pembrolizumab extended OS vs chemotherapy in patients with a PD-L1 combined positive score (CPS) ≥10. KE…
