BACKGROUND: Primary hepatic neuroendocrine carcinoma (PHNEC), which often lacks distinctive radiological features or specific clinical symptoms, is extremely rare. In this report, we describe a rare case of PHNEC that was successfully treated with hepatic arterial infusion chemotherapy (HAIC) combined with camrelizumab and targeted therapy. CASE DESCRIPTION: This report describes the treatment of a 53-year-old male with PHNEC in China. The patient was admitted for persistent upper right quadrant abdominal pain...

BACKGROUND: Hepatocellular carcinoma (HCC) ranks prominently in cancer-related mortality globally. Surgery remains the main therapeutic option for the treatment of HCC, but high post-operative recurrence rate makes prognostic prediction challenging. The quest for a reliable model to predict HCC recurrence continues to enhance prognosis. We aim to develop a nomogram with multiple factors to accurately estimate the risk of post-operative recurrence in patients with HCC. METHODS: A single-center retrospective study on 262 patients who underwent partial hepatectomy for HCC at the Eastern Hepatobiliary Surgery Hospital from May 2010 to April 2013 was conducted where immunohistochemistry assessed Yes-associated protein (YAP) expression in HCC...

BACKGROUND: Lactate dehydrogenase A ( LDHA ) plays a crucial role in the final step of anaerobic glycolysis, converting L-lactate and NAD+ to pyruvate and nicotinamide adenine dinucleotide (NADH). Its high expression has been linked to tumorigenesis and patient survival in various human cancers. However, the full implications of LDHA 's role and its correlation with clinicopathological features in pancreatic adenocarcinoma (PAAD) remain to be fully understood. This study was thus conducted to elucidate the specific functions of LDHA in PAAD, with the aim of providing more robust evidence for clinical diagnosis and treatment...

BACKGROUND: The incidence of multiple primary malignancies (MPMs) after early esophageal cancer is increasing. This study aimed to explore the clinical features of patients with MPMs and identify independent risk factors for the development of MPMs after endoscopic treatment in early esophageal squamous cell carcinoma (ESCC) patients. METHODS: Patients diagnosed as early ESCC at Beijing Friendship Hospital were retrospectively analyzed. Independent factors affecting MPMs were selected by univariate and multivariate Cox regression analyses...

BACKGROUND: Sleep traits have been linked to diseases; particularly, their impact on cancer has received increasing attention. This study aimed to investigate whether sleep traits have a causal relationship with colorectal cancer (CRC) using two-sample Mendelian randomization (TSMR). METHODS: Genetic instrumental variables (IVs) for seven sleep traits (sleep duration, ease of getting up in the morning, morning chronotype, daytime napping, insomnia symptoms, snoring, and daytime dozing) were selected from pooled data from published genome-wide association studies (GSWSs)...

BACKGROUND: Pancreatic adenocarcinoma (PAAD) is a highly lethal malignancy characterized by aggressive growth and poor prognosis. Understanding the molecular mechanisms underlying PAAD is crucial for developing effective therapies. This study aimed to explore the role of TM4SF1 and other key genes in PAAD progression, their prognostic implications, and therapeutic opportunities. METHODS: Differential gene expression analysis was performed using PAAD and normal tissue samples to identify upregulated genes, with TM4SF1 emerging as significantly elevated in PAAD...

BACKGROUND: CKLF-like MARVEL transmembrane domain-containing 4 (CMTM4) is involved in immune regulation and tumor progression; however, its role in gastric cancer (GC) remains unclear. This study explored the role and mechanism of CMTM4 in GC. METHODS: Immunohistochemistry was used to analyze CMTM4 expression in human gastric biopsied cells from patients with GC (N=23) or chronic superficial gastritis (N=23). To investigate the function of CMTM4 in GC cells, the gene CMTM4 was knocked down and overexpressed in human gastric adenocarcinoma cell line AGS...

BACKGROUND: Intrahepatic cholangiocarcinoma (iCCA) is a rare biliary tract cancer with increasing incidence and poor survival rates. This study aims to evaluate the incidence and survival trends of iCCA patients over 20 years using a national cancer database, and assess the temporal association between survival and landmark clinical trials. METHODS: Data was extracted from the Surveillance, Epidemiology, and End Results (SEER) database. Age-adjusted incidence rates (AAIRs) were calculated from 2000 to 2020...

On a global scale, gastric adenocarcinoma (GCa) accounts for a large burden of death from cancer. Despite advances in systemic therapy and surgical technique, the fatality rate for GCa remains unacceptably high in Europe and North America, where diagnosis is typically made at an advanced stage. Biomarkers that can accurately predict response to new therapies and provide novel therapeutic strategies are urgently sought. FAM46C, a putative noncanonical nucleotidyltransferase, has garnered interest for its tumor suppressor function in multiple myeloma...

BACKGROUND AND OBJECTIVE: Radiation therapy is one of the main pillars in the treatment of gastrointestinal (GI) cancers, especially esophageal and anorectal malignancies. The worldwide standard of care is yet an irradiation with photons. Though not commonly used, charged particles offer some physical advantages with a highly conformal dose distribution, which allows an even better sparing of organs at risk. In addition to dosimetric advantages, heavy-ion beams like carbon ions may offer an additional set of biological advantages...

BACKGROUND: Targeted therapy is a crucial treatment modality for advanced gastric cancer, with several targets already identified, and the exploration of new targets is important. In this study, our aim was to identify plasma proteins causally associated with gastric cancer to explore novel genetic targets for the disease. METHODS: Firstly, we utilized protein quantitative trait loci data for 4,907 plasma proteins and genome-wide association study data for gastric cancer to conduct Mendelian randomization (MR) analyses...

BACKGROUND: Anlotinib hydrochloride is a potent oral multitargeted tyrosine kinase inhibitor that targets VEGFR1-3, FGFR1-4, and PDGFR α/β, demonstrating significant antiangiogenic activity. Transcatheter arterial chemoembolization (TACE) is considered the effective treatment for intermediate/advanced hepatocellular carcinoma (HCC), which remains a major global health challenge. This study evaluated the relative efficacy and safety of combining anlotinib with TACE against the standard TACE monotherapy among patients with intermediate or advanced HCC...

BACKGROUND: Hyperthermic intraperitoneal chemotherapy (HIPEC) targets intraperitoneal tumors with heated drug solutions via catheters inserted into the peritoneal space. Although studies have focused on clinical outcomes, the flow dynamics at specific intra-abdominal locations at-risk of harboring malignant cells remain poorly understood but are likely to impact the drug pharmacokinetics. Consequently, optimal protocols remain uncertain, with efficacy critically dependent on drug temperature and flow rate...

BACKGROUND: Colorectal cancer (CRC) is the third most common form of cancer worldwide in terms of incidence and the second in terms of mortality with 1.9 million new cases and 930,000 deaths reported in 2020. Corresponding numbers in the U.S. are 150,000 and 53,000, respectively. Although the majority of CRCs in the U.S. and other high-income countries are in adults aged 50 and older, there has recently been a considerable rise in early-onset CRC, so that 17,930 cases in the U.S. (12% of total cases) are diagnosed in individuals younger than age 50, representing the equivalent of 49 new cases per day...

BACKGROUND: Single-agent immunotherapy is less effective in patients with DNA mismatch repair-proficient/microsatellite stable (pMMR/MSS) metastatic colorectal cancer (mCRC). Whether pMMR/MSS mCRC patients benefit from combination immunotherapy remains unclear. This study aimed to evaluate the efficacy and safety of anti-programmed cell death protein 1 (PD-1) therapy combined with chemotherapy and bevacizumab in pMMR/MSS colorectal liver metastases (CRLM) patients. METHODS: A total of 12 patients with pMMR/MSS CRLM treated at The Sixth Affiliated Hospital of Sun Yat-sen University were enrolled...

BACKGROUND: Randomized trials have shown a survival benefit for fruquintinib over placebo in patients with metastatic colorectal cancer (mCRC) that progressed after standard therapies, but real-world prognostic analyses have been seldom reported. We evaluated survival, safety outcomes, and predictive and prognostic factors in patients treated with fruquintinib in a real-life setting. METHODS: We conducted a multi-center study by collecting relevant data on patients with advanced colorectal cancer (CRC) who received fruquintinib, focusing on progression-free survival (PFS), overall survival (OS), and L3 skeletal muscle index (SMI), including safety follow-up...
