Prognostic immune markers in esophageal cancer patients managed with trimodal therapy.

Background: Esophageal cancer (ESC) is an aggressive disease which often presents at an advanced stage. Despite trimodal therapy, 40-50% patients can develop metastatic disease by 18 months. Identification of patients at risk for metastatic spread is challenging with need for improved prognostication.

Demographic Characteristics and Survival in Young-Onset Colorectal Neuroendocrine Neoplasms.

Background/objectives: Recent epidemiological studies have revealed an upward trend in young-onset colorectal cancer (YOCRC) overall, whereas specific data on young-onset colorectal neuroendocrine neoplasms (YONEN) remain limited. This study investigated the demographic characteristics and survival trends in YONEN and compared these with those of young-onset colorectal adenocarcinoma (YOADC), the most common histologic subtype of YOCRC.

Methods: A retrospective analysis was conducted from 2000 to 2019 using the Surveillance, Epidemiology, and End Results (SEER) database.

Role of immunotherapy in gastroesophageal cancer with liver metastasis.

The role of immune checkpoint inhibitors for patients with gastroesophageal cancer with liver metastasis remains unclear. Our objective was to investigate whether immune checkpoint inhibitors are beneficial in patients with gastroesophageal cancer with liver metastasis. We searched PubMed, Embase, European Society for Medical Oncology, and American Society of Clinical Oncology meeting abstracts for phase 3 randomized clinical trials testing immune checkpoint inhibitors in metastatic/advanced gastroesophageal cancer from 2017 to 2023.

TAS-102, Irinotecan, and bevacizumab in pre-treated metastatic colorectal cancer (TABAsCO), a phase II clinical trial.

Background: The efficacy of FOLFIRI plus an antiangiogenesis biologic agent as 2nd line therapy for metastatic colorectal adenocarcinoma is limited. TAS-102 is a novel oral antimetabolite with a distinct mechanism of action from fluoropyrimidines. We evaluated the antitumour efficacy of TAS-102, irinotecan and bevacizumab in patients with pre-treated, advanced colorectal adenocarcinoma in a multicenter, phase II, single-arm study.

Cancer/testis antigen expression and co-expression patterns in gastroesophageal adenocarcinoma.

Gastroesophageal adenocarcinoma (GEAC) poses a significant challenge due to its poor prognosis and limited treatment options. Recently, Cancer/testis antigens (CTAs) have emerged as potential therapy targets due to their high expression in tumor cells and their immunogenic nature. We aimed to explore the expression and co-expression of CTAs in GEAC.

Effects of Immunotherapy on Quality-of-Life Outcomes in Patients with Gastroesophageal Cancers: A Meta-Analysis of Randomized Controlled Trials.

Background: Immune checkpoint inhibitors (ICIs) have revolutionized cancer care, with increasing data demonstrating improved survival outcomes using ICIs among patients with advanced gastroesophageal cancer (GEC). ICIs are also associated with a lower incidence of grade ≥ 3 adverse events (AEs) compared to chemotherapy, suggesting that ICIs may have favorable effects on health-related quality of life (HRQoL). This meta-analysis sought to evaluate the effects of ICIs on the HRQoL of patients with advanced GEC.

Cancer/testis antigen expression and co-expression patterns in Gastroesophageal Adenocarcinoma.

Gastroesophageal adenocarcinoma (GEAC) poses a significant challenge due to its poor prognosis and limited treatment options. Recently, Cancer/testis antigens (CTAs) have emerged as potential therapy targets due to their high expression in tumor cells and their immunogenic nature. We aimed to explore the expression and co-expression of CTAs in GEAC.

Contemporary outcomes for resected type 1-3 gastroesophageal junction adenocarcinoma: a single-center experience.

Background: Surgical resection remains the mainstay of treatment for tumors of the gastroesophageal junction (GEJ). However, contemporary analyses of the Western experience for GEJ adenocarcinoma are sparsely reported.

Methods: Patients with GEJ adenocarcinoma undergoing resection between 2012 and 2022 at a single institution were grouped based on Siewert subtype and analyzed.

Exploring Demographic Differences and Outcomes in Early-Onset Colorectal Cancer.

Purpose: Early-onset colorectal cancer (EOCRC), defined as CRC diagnosed before age 50 years, has increased significantly worldwide. The majority of EOCRCs do not appear to be driven by genetic factors and may be influenced by environmental factors. We hypothesized that sociodemographic disparities exist in EOCRC.

Association between Environmental Temperature and Survival in Gastroesophageal Cancers: A Population Based Study.

Background: Cold stress suppresses antitumor response in animal models, leading to tumor growth. Recent studies have also shown a negative correlation between the average annual temperature (AAT) and cancer incidence. We hypothesized that esophageal cancer (EC) and gastric cancer (GC) patients living in warmer climates have improved survival outcomes than those living in colder climates.

Association between visceral obesity, metformin use, and recurrence risk in early-stage colorectal cancer.

We sought to investigate the association between visceral obesity with disease recurrence and survival in early-stage colorectal cancer (CRC) patients. We also wanted to examine if such an association, if exists, is influenced by metformin use. Stage I/II CRC adenocarcinoma patients treated surgically were identified.

Esophageal and Esophagogastric Junction Cancers, Version 2.2023, NCCN Clinical Practice Guidelines in Oncology.

Cancers originating in the esophagus or esophagogastric junction constitute a major global health problem. Esophageal cancers are histologically classified as squamous cell carcinoma (SCC) or adenocarcinoma, which differ in their etiology, pathology, tumor location, therapeutics, and prognosis. In contrast to esophageal adenocarcinoma, which usually affects the lower esophagus, esophageal SCC is more likely to localize at or higher than the tracheal bifurcation.

Geographical Disparities in Esophageal Cancer Incidence and Mortality in the United States.

Background: Our previous research on neuroendocrine and gastric cancers has shown that patients living in rural areas have worse outcomes than urban patients. This study aimed to investigate the geographic and sociodemographic disparities in esophageal cancer patients.

Methods: We conducted a retrospective study on esophageal cancer patients between 1975 and 2016 using the Surveillance, Epidemiology, and End Results database.

Aging augments obesity-induced thymic involution and peripheral T cell exhaustion altering the "obesity paradox".

Introduction: The incidence of obesity, a condition characterized by systemic chronic inflammation, has reached pandemic proportions and is a poor prognostic factor in many pathologic states. However, its role on immune parameters has been diverse and at times contradictory. We have previously demonstrated that obesity can result in what has been called the "obesity paradox" which results in increased T cell exhaustion, but also greater efficacy of immune checkpoint blockade in cancer treatment.

The evolving role of radiation in pancreatic cancer.

Pancreatic cancer is the fourth leading cause of cancer mortality in the United States. Chemotherapy in resectable pancreatic cancer has improved survival by 10-20%. It only converted 10-30% of the borderline resectable and locally advanced pancreatic cancers to be surgically resectable.

Immunotherapy and Targeted Therapy for Advanced Gastroesophageal Cancer: ASCO Guideline.

Purpose: To develop recommendations involving targeted therapies for patients with advanced gastroesophageal cancer.

Methods: The American Society of Clinical Oncology convened an Expert Panel to conduct a systematic review of relevant studies and develop recommendations for clinical practice.

Results: Eighteen randomized controlled trials met the inclusion criteria for the systematic review.

Immune checkpoint inhibitors in resectable gastroesophageal cancers - a review.

Gastroesophageal cancers (GEC) have a poor survival rate of 20-30% at 5 years, often due to delayed presentations. Neoadjuvant chemoradiotherapy (CRT) followed by surgery or peri-operative chemotherapy and surgery are widely used as the standard of care for patients with resectable GEC. Immune checkpoint inhibitors (ICIs) have improved survival in metastatic and recurrent GEC which led to their application in resectable GEC.

Optimal First-Line Therapy for Metastatic Adenocarcinoma of the Esophagus.

Treatment strategies for esophageal adenocarcinoma patients continue to advance with the generation of more data from clinical trials that are permitting us to refine the use of immunotherapy in combination with other treatment modalities. While the frontline therapy for metastatic esophageal adenocarcinoma has become more complicated with the approval of combination regimens, it is also yielding better outcomes. These treatment strategies can now be individualized to fit patient circumstances and goals as well as the biomarker profile of their individual tumors leading to an increased likelihood of treatment related remissions and extended median survivals.

Anti PD-1/Anti PDL-1 Inhibitors in Advanced Gastroesophageal Cancers: A Systematic Review and Meta-Analysis of Phase 2/3 Randomized Controlled Trials.

Importance: Immune checkpoint inhibitors (ICI) have revolutionized the treatment for gastroesophageal cancers (GEC). It is important to investigate the factors that influence the response to anti-PD-1/PD-L1 ICIs. Objective: To assess the benefits of PD-1/PD-L1 ICIs in advanced GEC and perform subgroup analysis to identify patient populations who would benefit from ICI.

Adenoviral-based vaccine promotes neoantigen-specific CD8 T cell stemness and tumor rejection.

Upon chronic antigen exposure, CD8 T cells become exhausted, acquiring a dysfunctional state correlated with the inability to control infection or tumor progression. In contrast, stem-like CD8 T progenitors maintain the ability to promote and sustain effective immunity. Adenovirus (Ad)-vectored vaccines encoding tumor neoantigens have been shown to eradicate large tumors when combined with anti-programmed cell death protein 1 (αPD-1) in murine models; however, the mechanisms and translational potential have not yet been elucidated.

The anticancer effect of statins in obese esophageal cancer patients undergoing esophagectomy.

Background: In addition to treating hyperlipidemia and atherosclerosis, statins have demonstrated anti-inflammatory and antitumor activity in various cancers. We evaluate this effect in esophageal cancer patients undergoing esophagectomy.

Methods: Esophageal cancer patients undergoing esophagectomy at Roswell Park Comprehensive Cancer Center between March 2007 and December 2015 were included.

Exploring the Impact of the Obesity Paradox on Lung Cancer and Other Malignancies.

There is a paradoxical relationship between obesity, as measured by BMI, and many types of cancer, including non-small-cell lung cancer. Obese non-small-cell lung cancer patients have been shown to fare better than their non-obese counterparts. To analyze the multifaceted effects of obesity on oncologic outcomes, we reviewed the literature on the obesity paradox, methods to measure adiposity, the obesity-related derangements in immunology and metabolism, and the oncologic impact of confounding variables such as gender, smoking, and concomitant medications such as statins and metformin.
