Electrolyte disorders assessment in solid tumor patients treated with anti-EGFR monoclonal antibodies : a pooled analysis of 25 randomized clinical trials

The role of anti-epithelial growth factor receptor monoclonal antibodies (anti-EGFR MoAbs) in treatment-related electrolyte disorders is still controversial. Therefore, we conducted a meta-analysis of published randomized controlled trials (RCTs) to evaluate the incidences and overall risks of all-grade and grade 3/4 electrolyte disorder events. We searched relevant clinical trials from PubMed, EM

Heteroplasmy of mutant mitochondrial DNA A10398G and analysis of its prognostic value in non-small cell lung cancer

Mitochondrial dysfunction is associated with pathogenic mitochondrial (mt)DNA mutations. The majority of mtDNA point mutations have a heteroplasmic status, which is defined as the coexistence of wild-type and mutated DNA within a cell or tissue. Previous findings demonstrated that certain mtDNA heteroplasmic mutations contribute to widely spread chronic diseases, including cancer, and alterations

Concomitant underexpression of TGFBR2 and overexpression of hTERT are associated with poor prognosis in cervical cancer

The human telomerase reverse transcriptase (hTERT) is highly expressed in a variety of tumors. The transforming growth factor beta receptor type II (TGFBR2) is a downstream protein of transforming growth factor beta (TGF-β) which suppresses telomerase activity. However, the relevance of survival to the expression of TGFBR2, hTERT or TGFBR2/hTERT has not been previously investigated in cervical can

Smoking Cessation and Risk of Esophageal Cancer by Histological Type : Systematic Review and Meta-analysis

BACKGROUND: Tobacco smoking strongly increases risk of esophageal squamous cell carcinoma and moderately increases risk of esophageal adenocarcinoma. How smoking cessation influences esophageal cancer risk across histological subtypes, time latencies, and geographic regions is not clear.METHODS: Studies were systematically searched on Medline, Embase, Web of Science, Cochrane Library, and Clinical

Global time trends in the incidence of esophageal squamous cell carcinoma

BACKGROUND AND AIMS: Esophageal squamous cell carcinoma (ESCC) is the dominant histological type of esophageal cancer worldwide (90%). We aimed to provide an update of the global temporal trends in the incidence of ESCC.METHODS: Incidence data for ESCC were collected from 30 well-established cancer registries from 20 countries in Europe, Northern America, Australia, or Asia for 1970-2015. Time tre

Prediction of individuals at high absolute risk of esophageal squamous cell carcinoma

BACKGROUND AND AIMS: This study aimed to develop a prediction model for identifying individuals at high absolute risk of esophageal squamous cell carcinoma (ESCC) for endoscopic screening at a curable stage based on readily identifiable risk factors.METHODS: This was a nationwide Swedish population-based, case-control study, including 167 new cases of ESCC and 820 randomly selected control partici

Association Between Metformin Use and Risk of Esophageal Squamous Cell Carcinoma in a Population-Based Cohort Study

OBJECTIVES: Esophageal cancer is a highly fatal malignant neoplasm, with 2 etiologically different histological types. A large prospective study is expected to elucidate the specific risk of the 90% subtype of esophageal cancer, esophageal squamous cell carcinoma (ESCC), with metformin therapy. This study aims to determine the association between metformin use and incident ESCC risk.METHODS: This

Development and external validation of a COVID-19 mortality risk prediction algorithm : a multicentre retrospective cohort study

OBJECTIVE: This study aimed to develop and externally validate a COVID-19 mortality risk prediction algorithm.DESIGN: Retrospective cohort study.SETTING: Five designated tertiary hospitals for COVID-19 in Hubei province, China.PARTICIPANTS: We routinely collected medical data of 1364 confirmed adult patients with COVID-19 between 8 January and 19 March 2020. Among them, 1088 patients from two desi

Development and Validation of a Risk Prediction Model for Esophageal Squamous Cell Carcinoma Using Cohort Studies

INTRODUCTION: Esophageal squamous cell carcinoma (ESCC) carries a poor prognosis, but earlier tumor detection would improve survival. We aimed to develop and externally validate a risk prediction model based on exposure to readily available risk factors to identify high-risk individuals of ESCC.METHODS: Competing risk regression modeling was used to develop a risk prediction model. Individuals' ab

Longitudinal trajectories of lifetime body shape and prostate cancer angiogenesis

Angiogenesis potentially underlies the pathway between excess adiposity and prostate carcinogenesis. This study examined the association between lifetime body shape trajectories and prostate cancer angiogenesis. 521 prostate cancer patients who underwent prostatectomy or transurethral resection between 1986 and 2000 were enrolled from the Health Professionals Follow-up Study. Cancers were immunost

Sugar-sweetened beverage and sugar consumption and colorectal cancer incidence and mortality according to anatomic subsite

BACKGROUND: Recent preclinical research strongly suggests that dietary sugars can enhance colorectal tumorigenesis by direct action, particularly in the proximal colon that unabsorbed fructose reaches.OBJECTIVES: We aimed to examine long-term consumption of sugar-sweetened beverages (SSBs) and total fructose in relation to incidence and mortality of colorectal cancer (CRC) by anatomic subsite.METH

The age-dependent association of risk factors with pancreatic cancer

BACKGROUND: Pancreatic cancer presents as advanced disease in >80% of patients; yet, appropriate ages to consider prevention and early detection strategies are poorly defined. We investigated age-specific associations and attributable risks of pancreatic cancer for established modifiable and non-modifiable risk factors.PATIENTS AND METHODS: We included 167 483 participants from two prospective US

Temporal Association of Total Serum Cholesterol and Pancreatic Cancer Incidence

Previous studies have suggested a “cholesterol-lowering effect” of preclinical pancreatic cancer, suggesting lower total cholesterol as a potential diagnostic marker. Leveraging repeated measurements of total cholesterol, this study aims to examine the temporal association of total cholesterol and pancreatic cancer incidence. We conducted a nested case-control study based on a Korean National Heal

Historical Pathogen-Driven Selection May Contribute to Contemporary Ethnic Difference in Bladder Cancer Susceptibility

BACKGROUND: The rationale for ethnic differences in bladder cancer (BCa) susceptibility is an important open question. In this study, we raised the hypothesis that the APOBEC3-rs1014971 variant associated with BCa risk and APOBEC-mutagenesis probably contribute to ethnic differences. METHODS: We calculated the ethnicity-stratified 5-year age-adjusted incidence rates of BCa using the US SEER databa

Sex-Specific Associations between Adiponectin and Leptin Signaling and Pancreatic Cancer Survival

BACKGROUND: Circulating adiponectin and leptin have been associated with risk of pancreatic cancer. However, the relationship between long-term exposure to these adipokines in the prediagnostic period with patient survival has not been investigated.METHODS: Adipokine levels were measured in prospectively collected samples from 472 patients with pancreatic cancer. Because of sex-specific difference

Diabetes, metformin use, and survival in esophageal cancer : a population-based cohort study

BACKGROUND: It is unclear how diabetes and metformin use is associated with survival of esophageal cancer.METHODS: This population-based cohort study included new cases of esophageal cancer reported in Sweden from 2006 to 2018 with follow-up through 2019. Diabetes status and metformin use were analyzed in relation to all-cause and disease-specific mortality using multivariable Cox regression. The

Risk of estrogen receptor-specific breast cancer by family history of estrogen receptor subtypes and other cancers

BACKGROUND: The extent to which the risk of estrogen receptor (ER)-specific breast cancer is associated with ER status of breast cancer and other cancers among first-degree relatives is unclear.METHODS: This population-based cohort included 464 707 cancer-free women in Stockholm, Sweden, during 1978-2019. For ER-negative and ER-positive breast cancers, we estimated hazard ratios (HRs) associated w

Analysis of Breast Cancer Family History, Estrogen Receptor Status, and Breast Cancer Outcomes in Sweden

IMPORTANCE: Breast cancer (BC), the most prevalent cancer among women globally, is a heterogeneous disease, with prognosis differing by estrogen receptor (ER) status. Having a family history of BC increases the risk of BC; however, it is unclear whether family history is associated with the prognosis of overall and ER-specific BC.OBJECTIVE: To assess whether a family history of BC is associated wi
