Safety of current treatments for advanced cholangiocarcinoma.

Introduction: Biliary tract cancer (BTC) originates from the biliary epithelium of the small ducts within the liver (intrahepatic cholangiocarcinoma, IHCC), the main ducts of the hilum (extrahepatic cholangiocarcinoma, EHCC), or in the gallbladder (gallbladder cancer, GC). Due to presentation with nonspecific symptoms as well as absence of screening, most patients present with advanced disease and unfavorable prognosis.

Areas Covered: The ABC-02 trial established the current first-line chemotherapy with gemcitabine/platinum for advanced BTC in 2010.

Adjuvant chemotherapy versus preoperative chemotherapy for gastric cancer treated with curative-intent resection: A propensity score-matched analysis.

Background: Multimodal therapy (MMT), comprising surgery alongside perioperative chemotherapy (PCMT) or adjuvant chemotherapy (ACMT), has demonstrated improve in survival compared with surgery alone for advanced gastric cancer (GC). However, the moment of administering chemotherapy for GC is still a matter of debate. This study aimed to compare PCMT and ACMT in patients with locally advanced GC.

Identification of a prognostic disulfidptosis-related gene signature in hepatocellular cancer.

Background: Disulfidptosis regulate various biological processes in cancer. However, there is limited research on the genes related to disulfidptosis in predicting the prognosis of hepatocellular carcinoma (HCC). We aimed to develop a reliable disulfidptosis-related gene signature, which will characterize different HCC subtypes and predict their prognosis.

NOVA2 regulates the properties of liver cancer stem cells and lenvatinib resistance in hepatocellular carcinoma via the Wnt pathway.

Background: The regulation of cancer stem cells (CSCs) is influenced by RNA-binding proteins (RBPs). The present study sought to investigate the role of NOVA2 in the processes of self-renewal, carcinogenesis, and lenvatinib resistance in liver CSCs.

Methods: Neuro-oncological ventral antigen 2 (NOVA2) expression in liver CSCs was examined by real-time polymerase chain reaction (PCR).

Real-World Effectiveness of First Line Lenvatinib Therapy in Advanced Hepatocellular Carcinoma: Current Insights.

Lenvatinib received its initial approval in 2018 for the treatment of advanced hepatocellular carcinoma. It has since emerged as the preferred first line agent, supported by non-inferiority data from the REFLECT trial. Notably, lenvatinib exhibits a more favorable toxicity profile and a higher response rate compared to sorafenib.

Support Through Remote Observation and Nutrition Guidance (STRONG), a digital health intervention to reduce malnutrition among pancreatic cancer patients: A study protocol for a pilot randomized controlled trial.

Background: Malnutrition is a common and distressing condition among pancreatic cancer patients. Fewer than a quarter of pancreatic cancer patients receive medical nutrition therapy (MNT), important for improving nutritional status, weight maintenance, quality of life and survival. System, provider, and patient level barriers limit access to MNT.

Efficacy and safety of Zolbetuximab plus chemotherapy for advanced CLDN18.2-positive gastric or gastro-oesophageal adenocarcinoma: a meta-analysis of randomized clinical trials.

Background: The benefit of adding Zolbetuximab to the treatment in patients with Claudin-18 isoform 2 (CLDN18.2)-positive, human epidermal growth factor receptor 2-negative, locally advanced unresectable or metastatic gastric or gastro-oesophageal junction adenocarcinoma (GC/GEJ) is not yet fully elucidated.

Methods: We searched PubMed, Embase and Cochrane databases for randomized controlled trials (RCTs) that investigated Zolbetuximab plus chemotherapy versus chemotherapy alone for GC or GEJ adenocarcinoma.

Prognostic Impact of Primary Tumor Sidedness in Stage III Colorectal Cancer: Real-World Evidence from a Brazilian Cohort.

Background: Primary tumor sidedness (PTS) is an independent prognostic factor in patients with metastatic colorectal cancer (CRC), with a worse prognosis for right-sided tumors. There are limited data on the prognostic impact of PTS in stage III CRC. The main objective of this study was to analyze the prognostic impact of PTS in stage III CRC.

CT Imaging Assessment of Pancreatic Adenocarcinoma Resectability after Neoadjuvant Therapy: Current Status and Perspective on the Use of Radiomics.

Pancreatic adenocarcinoma (PDAC) is the most common pancreatic cancer and is associated with poor prognosis, a high mortality rate, and a substantial number of healthy life years lost. Surgical resection is the primary treatment option for patients with resectable disease; however, only 10-20% of all patients with PDAC are eligible for resection at the time of diagnosis. In this context, neoadjuvant therapy has the potential to increase the number of patients who are eligible for resection, thereby improving the overall survival rate.

Africa Guidelines for Hepatocellular Carcinoma Buildup Process.

Purpose: Hepatocellular carcinoma (HCC), the fourth most common cancer in Africa, has a dismal overall survival of only 3 months like in sub-Saharan Africa. This is affected by the low gross domestic product and human development index, absence of coherent guidelines, and other factors.

Methods: An open forum for HCC-experienced health care workers from Africa and the rest of the world was held in October 2021.

Determinants of Survival with Combined HER2 and PD-1 Blockade in Metastatic Esophagogastric Cancer.

Purpose: We report updated clinical outcomes from a phase II study of pembrolizumab, trastuzumab, and chemotherapy (PTC) in metastatic esophagogastric cancer in conjunction with outcomes from an independent Memorial Sloan Kettering (MSK) cohort.

Patients And Methods: The significance of pretreatment 89Zr-trastuzumab PET, plasma circulating tumor DNA (ctDNA) dynamics, and tumor HER2 expression and whole exome sequencing was evaluated to identify prognostic biomarkers and mechanisms of resistance in patients treated on-protocol with PTC. Additional prognostic features were evaluated using a multivariable Cox regression model of trastuzumab-treated MSK patients (n = 226).

Immunotherapy and Targeted Therapy for Advanced Biliary Tract Cancer: Adding New Flavors to the Pizza.

Biliary tract cancers (BTCs) are a rare pathology and can be divided into four major subgroups: intrahepatic cholangiocarcinoma, extrahepatic cholangiocarcinoma, hilar cholangiocarcinoma, and gallbladder cancer. In the era of precision oncology, the development of next-generation sequencing (NGS) allowed a better understanding of molecular differences between these subgroups. Thus, the development of drugs that can target these alterations and inhibit the abnormal pathway activation has changed the prognosis of BTC patients.

Tremelimumab and durvalumab in the treatment of unresectable, advanced hepatocellular carcinoma.

Liver cancer is the third most common cause of cancer-related mortality worldwide, with over 780,000 deaths in 2018. About 90% of liver cancer cases are hepatocellular carcinoma (HCC), a prototype of inflammation-driven cancer, leading to a robust rationale for the exploration of immune therapy. Previously approved agents for first-line therapy, such as sorafenib, lenvatinib and bevacizumab combined with atezolizumab, have focused on angiogenesis.

The development and validation of a novel senescence-related long-chain non-coding RNA (lncRNA) signature that predicts prognosis and the tumor microenvironment of patients with hepatocellular carcinoma.

Background: The epigenetic regulators of cellular senescence, especially long non-coding RNAs (lncRNAs), remain unclear. The expression levels of lncRNA were previously known to be prognostic indicators for tumors. We hypothesized that lncRNAs regulating cellular senescence could also predict prognosis in patients with hepatocellular carcinoma (HCC) and developed a novel lncRNA predictive signature.

SURGICAL TREATMENT IN CLINICAL STAGE IV GASTRIC CANCER: A COMPARISON OF DIFFERENT PROCEDURES AND SURVIVAL OUTCOMES.

Aim: Even in clinical stage IV gastric cancer (GC), surgical procedures may be required to palliate symptoms or in an attempt to improve survival. However, the limited survival of these patients raises doubts about who really had benefits from it. This study aimed to analyze the surgical outcomes in stage IV GC treated with surgical procedures without curative intent.
