We retrospectively collected 857 patients with Barcelona Clinic Liver Cancer (BCLC) stage 0 or A HCC who underwent primary resection at Kaohsiung Chang Gung Hospital between January 2001 and June 2016. The patients were randomized into derivation (n = 648) and validation groups (n = 209). Logistic regression analysis was used to screen out independent risk factors for MVI and further constructed a predictive model for MVI. Prediction performance was compared by the area under the receiver operating characteristic curve (AUC). The multivariable logistic regression analysis of the training cohort found that alpha-fetoprotein (AFP) ≥ 20 ng/mL (OR = 1.96, 95% CI: 1.41-2.73, P < 0.001), albumin < 3.5 g/dL (OR = 1.48, 95% CI: 1.06-2.05, P = 0.019) and tumor burden score (TBS) ≥ 8.6 (OR = 2.54, 95% CI: 1.49-4.35, P = 0.001) to be independent risk factors for MVI.

Despite the nearly 2,000 publications on chemotherapy-related ototoxicity in the past decade, the understanding of its prevalence, mechanisms, and preventative or therapeutic measures remains ambiguous and subject to debate. To date, only one drug, sodium thiosulfate, has gained FDA approval for treating ototoxicity in chemotherapy. However, its utilization is restricted. This review aims to offer clinicians and researchers a comprehensive perspective by thoroughly and carefully reviewing available data and current evidence. Chemotherapy-induced ototoxicity is characterized by four primary symptoms: hearing loss, tinnitus, vertigo, and dizziness, originating from both auditory and vestibular systems. Hearing loss is the predominant symptom. Amongst over 700 chemotherapeutic agents documented in various databases, only seven are reported to induce hearing loss. While the molecular mechanisms of the hearing loss caused by the two platinum-based drugs are extensively explored, the pathways behind the action of the other five drugs are primarily speculative, rooted in their therapeutic properties and side effects. Cisplatin attracts the majority of attention among these drugs, encompassing around two-thirds of the literature regarding ototoxicity in chemotherapy. Cisplatin ototoxicity chiefly manifests through the loss of outer hair cells, possibly resulting from damages directly by cisplatin uptake or secondary effects on the stria vascularis. Both direct and indirect influences contribute to cisplatin ototoxicity, while it is still debated which path is dominant or where the primary target of cisplatin is located. Candidates for hearing protection against cisplatin ototoxicity are also discussed, with novel strategies and methods showing promise on the horizon.</p>","PeriodicalId":7437,"journal":{"name":"American journal of cancer research","volume":"14 9","pages":"4597-4632"},"PeriodicalIF":3.6,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11477841/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142455807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is an urgent need to further understand its underlying molecular mechanisms and identify new biomarkers for early detection. Zinc, a critical trace element and catalytic cofactor, is tightly regulated within cells. ZIP4, a zinc transporter protein significantly overexpressed in human pancreatic cancer, appears to play a pivotal role in tumor development by modulating intracellular zinc concentration. This review highlights the role of ZIP4 in tumorigenesis, including its impact on pancreatic cancer growth, proliferation, migration, and drug resistance. ZIP4 exerts its effects by regulating zinc dependent transcriptional factors like CREB, STAT3, and ZEB1, resulting in upregulation of Cyclin D1, TP53INP1, ITGA3, CD44, ENT1 proteins, and miR-373. Moreover, ZIP4 mediates the miR373-PHLPP2-AKT signaling axis, which increases TGF-β expression. Coupled with CREB-activated macrophage catabolism-related genes SDC1 and DNM2, ZIP4 promotes cancer cachexia and supports amino acids to tumor cells under metabolic stress. Furthermore, ZIP4 facilitates bone resorption by osteoclasts via the RANKL-activated NF-κB pathway. A deeper understanding of these mechanisms may unveil potential targets for early diagnosis, prognosis assessment, and dietary recommendations for pancreatic cancer.

With the global rise in MASLD prevalence, concurrent MASLD and chronic hepatitis B (CHB)-related hepatocellular carcinoma (HCC) are becoming increasingly common. This study aimed to evaluate the clinical impact of concurrent MASLD on long-term survival outcomes in patients with CHB-related early-stage HCC following curative resection. This retrospective study included patients diagnosed with CHB-related early-stage HCC who underwent curative hepatectomy between January 2010 and December 2019. We examined the association between histologically confirmed MASLD and clinical outcomes, with overall survival (OS) and recurrence-free survival (RFS) calculated using the Kaplan-Meier method and compared using the log-rank test. Of 587 eligible patients, 275 (46.8%) were diagnosed with concurrent MASLD. Patients with concurrent MASLD had a higher prevalence of diabetes, hypertension, body mass index (BMI) > 23 kg/m<sup>2</sup>, a lower proportion of AFP > 200 ng/ml, and microvascular invasion compared to those without MASLD. After a median follow-up of 66 months, patients with concurrent MASLD exhibited a lower risk of death (HR: 0.57, 95% CI: 0.34-0.95, <i>P</i> = 0.030) but no significant difference in HCC recurrence rates. Subgroup analysis revealed significantly higher OS in females, individuals with BMI ≥ 23 kg/m<sup>2</sup>, and non-cirrhotic patients (all <i>P</i> < 0.05). In conclusion, concurrent MASLD is associated with improved survival in patients with CHB-related HCC following curative resection, particularly in females, those with BMI ≥ 23 kg/m<sup>2</sup>, and non-cirrhotic patients.</p>","PeriodicalId":7437,"journal":{"name":"American journal of cancer research","volume":"14 9","pages":"4567-4579"},"PeriodicalIF":3.6,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11477822/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142455810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
