Abstract
With one of the highest mortality rates of all malignancies, the 5-year survival rate for esophageal cancer is under 20%. Depending on the stage and extent of the disease, the current standard of care treatment paradigm includes chemotherapy or chemoradiotherapy followed by surgical esophagogastrectomy, with consideration for adjuvant immunotherapy for residual disease. This regimen has high morbidity, due to anatomic changes inherent in surgery, the acuity of surgical complications, and off-target effects of systemic chemotherapy and immunotherapy. We begin with a review of current treatments, then discuss new and emerging targets for therapies and advanced drug delivery systems. Recent and ongoing preclinical and early clinical studies are evaluating traditional tumor targets (e.g., human epidermal growth factor receptor 2), as well as promising new targets such as Yes-associated protein 1 or mammalian target of rapamycin to develop new treatments for this disease. Due the function and location of the esophagus, opportunities also exist to pair these treatments with a drug delivery strategy to increase tumor targeting, bioavailability, and intratumor concentrations, with the two most common delivery platforms being stents and nanoparticles. Finally, early results with antibody drug conjugates and chimeric antigenic receptor T cells show promise as upcoming therapies. This review discusses these innovations in therapeutics and drug delivery in the context of their successes and failures, with the goal of identifying those solutions that demonstrate the most promise to shift the paradigm in treating this deadly disease.

Efficacy of Neoadjuvant Chemotherapy DOX and XELOX Regimens for Patients with Resectable Gastric or Gastroesophageal Junction Adenocarcinoma. Gastroenterol Res Pract 2021; 2021:5590626. [PMID: 34335737 PMCID: PMC8324337 DOI: 10.1155/2021/5590626] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2021] [Revised: 06/29/2021] [Accepted: 07/01/2021] [Indexed: 11/17/2022] Open
Abstract
Purpose This paper is aimed at comparing the short-term efficacy of the combination of docetaxel, oxaliplatin, and capecitabine (DOX) with the combination of oxaliplatin and capecitabine (XELOX) as neoadjuvant chemotherapy regimens for the treatment of patients with resectable gastric or gastroesophageal junction adenocarcinoma. Methods A total of 300 patients aged 20-60 years with resectable gastric or gastroesophageal junction adenocarcinoma who were evaluated with cT3/4Nany were randomly assigned into 3 groups: DOX group (n = 100, treated with neoadjuvant DOX plus adjuvant XELOX), XELOX group (n = 100, treated with perioperative XELOX), and surgery group (n = 100, treated with adjuvant XELOX). Results A total of 93, 92, and 95 patients were enrolled in the DOX, XELOX, and surgery groups, respectively. The pathological complete response (pCR) rate was 16.1% in the DOX group and 4.3% in the XELOX group (P = 0.008). There were 56 (61.3%) patients in the DOX group who presented with surgical complications, 22 (23.9%) patients in the XELOX group, and 37 (38.9%) patients in the surgery group. The most common grade 3-4 adverse events in these three groups were neutropenia (32.3%, 30.4%, and 21.1%), leucopenia (21.5%, 22.8%, and 15.8%), nausea (15.1%, 16.3%, and 12.6%), and fatigue (10.8%, 7.6%, and 8.4%). Conclusions Neoadjuvant DOX is an effective and feasible regimen and might represent an option for young and middle-aged patients with locally advanced, resectable gastric or gastroesophageal junction adenocarcinoma.

The bromodomain inhibitor IBET-151 attenuates vismodegib-resistant esophageal adenocarcinoma growth through reduction of GLI signaling. Oncotarget 2020; 11:3174-3187.

Abstract
The Hedgehog/GLI (HH/GLI) signaling pathway plays a critical role in human oncogenesis. Unfortunately, the clinical use of HH inhibitor(s) has been associated with serious adverse effects and mutation-related drug resistance. Since the efficacy of SMO (Smoothened) and GLI inhibitors is limited in clinical trials, there remains a critical need for the HH/GLI pathway inhibitors with different mechanisms of action. Here, we show that esophageal adenocarcinoma (EAC) cell lines are insensitive to vismodegib (SMO inhibitor) but respond to GANT61 (GLI1 inhibitor). Furthermore, we examine the role of GLI1 in tumorigenicity of EAC and how a selective bromodomain inhibitor IBET-151 downregulates transcriptional activity of the GLI1 transcription factor in EAC. Our study demonstrates that GLI1 plays an important role in tumorigenicity of EAC and that elevated GLI1 expression in patients’ ultrasound-assisted endoscopic biopsy may predict the response to neoadjuvant chemotherapy (NAC) FOLFOX. Importantly, IBET-151 abrogates the growth of vismodegib-resistant EAC cells and downregulates HH/GLI by reducing the occupancy of BRD4 at the GLI1 locus. IBET-151 also attenuates tumor growth of EAC-PDXs and does so in an on-target manner as it reduces the expression of GLI1. We identify HH/GLI signaling as a novel druggable pathway in EAC as well as validate an ability of clinically relevant GLI inhibitor to attenuate the viability of vismodegib-resistant EAC cells. Therefore, we propose that selective bromodomain inhibitors, such as IBET-151, could be used as novel therapeutic agents for EAC patients harboring GLI-dependent tumors.

Systematic review and meta-analysis of docetaxel perioperative chemotherapy regimens in gastric and esophagogastric tumors. Sci Rep 2019; 9:15806. [PMID: 31676841 PMCID: PMC6825156 DOI: 10.1038/s41598-019-52334-y] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2018] [Accepted: 10/15/2019] [Indexed: 02/07/2023] Open
Abstract
FLOT regimen became the standard perioperative treatment in several centers around the world for esophagogastric tumors despite concerns about toxicity. In addition, FLOT has never been compared with other docetaxel-based regimens. To address this question, we conducted a systematic review of PubMed, Embase and Web of Science including prospective or retrospective studies of docetaxel based perioperative regimen in gastric and esophagogastric tumors. Data regarding chemotherapy regimens, efficacy and toxicity were extracted. Outcomes were compared using a random effects model. Of 548 abstracts, 16 were considered eligible. Comparing the studies with meta-analysis we can see that the regimens are similar in terms of pathological complete response, resection rate, progression free survival and overall survival in one year, without significant heterogeneity. The meta-regression of docetaxel dose failed to show any association with dose ranging between 120–450 mg/m². Regarding the toxicity of the regimens it is noted that the regimens are quite toxic (up to 50–70% of grade 3–4 neutropenia). The results of this meta-analysis with a combined sample size of more than 1,000 patients suggest that docetaxel perioperative regimens are equivalent in outcomes. Prospective trials addressing modified regimens should be performed to provide less toxic strategies and be applicable to all patients.

Abstract
Oesophageal cancer is a relatively uncommon malignancy, but with poor prognosis. Despite several treatment options that are available, the 5-year survival rates rarely exceed 40%. This review discusses the main challenges of oesophageal cancer, the available treatment options, and the most effective treatment in terms of overall survival. The outcomes of clinical trials show that neo-adjuvant chemo-radiotherapy using cisplatin and 5-fluorouracil followed by oesophagectomy results in the greatest survival. However, the optimal chemotherapy and radiotherapy schedule remains unclear. There is no satisfactory treatment to date, particularly for patients with co-morbidities or advanced tumours.

Abstract
Esophageal adenocarcinoma ranks sixth in cancer mortality in the world and its incidence has risen dramatically in the Western population over the last decades. Data presented herein strongly suggest that Notch signaling is critical for esophageal adenocarcinoma and underlies resistance to chemotherapy. We present evidence that Notch signaling drives a cancer stem cell phenotype by regulating genes that establish stemness. Using patient-derived xenograft models, we demonstrate that inhibition of Notch by gamma-secretase inhibitors (GSI) is efficacious in downsizing tumor growth. Moreover, we demonstrate that Notch activity in a patient's ultrasound-assisted endoscopic-derived biopsy might predict outcome to chemotherapy. Therefore, this study provides a proof of concept that inhibition of Notch activity will have efficacy in treating esophageal adenocarcinoma, offering a rationale to lay the foundation for a clinical trial to evaluate the efficacy of GSI in esophageal adenocarcinoma treatment.

Abstract
Background This phase I/II-trial assessed the dose-limiting toxicities (DLT) and maximum tolerated dose (MTD) of neoadjuvant radiochemotherapy (RCT) with docetaxel and oxaliplatin in patients with locally advanced adenocarcinoma of the oesophagogastric junction. Methods Patients received neoadjuvant radiotherapy (50.4 Gy) together with weekly docetaxel (20 mg/m2 at dose level (DL) 1 and 2, 25 mg/m2 at DL 3) and oxaliplatin (40 mg/m2 at DL 1, 50 mg/m2 at DL 2 and 3) over 5 weeks. The primary endpoint was the DLT and the MTD of the RCT regimen. Secondary endpoints included overall response rate (ORR) and progression-free survival (PFS). Results A total of 24 patients were included. Four patients were treated at DL 1, 13 patients at DL 2 and 7 patients at DL 3. The MTD of the RCT was considered DL 2 with docetaxel 20 mg/m2 and oxaliplatin 50 mg/m2. Objective response (CR/PR) was observed in 32% (7/22) of patients. Eighteen patients (75%) underwent surgery after RCT. The median PFS for all patients (n = 24) was 6.5 months. The median overall survival for all patients (n = 24) was 16.3 months. Patients treated at DL 2 had a median overall survival of 29.5 months. Conclusion Neoadjuvant RCT with docetaxel 20 mg/m2 and oxaliplatin 50 mg/m2 was effective and showed a good toxicity profile. Future studies should consider the addition of targeted therapies to current neoadjuvant therapy regimens to further improve the outcome of patients with advanced cancer of the oesophagogastric junction.
