BACKGROUND: Epidermal growth factor receptor (EGFR) mutations occur in about 50% of Asian patients with non-small cell lung cancer (NSCLC). Patients with advanced NSCLC and EGFR mutations derive clinical benefit from treatment with EGFR-tyrosine kinase inhibitors (TKIs). This study assessed the efficacy and safety of adjuvant icotinib without chemotherapy in EGFR-mutated NSCLC patients undergoing resection of stage IB-IIIA. METHODS: Our retrospective study enrolled 20 patients treated with icotinib as adjuvant therapy...

The World Health Organization (WHO) classification from 2014 differentiates between different subtypes of mucinous adenocarcinoma of the uterine cervix. A gastric subtype was recently described that showed no association with high-risk human papillomavirus (HPV) infections, has a poor prognosis, is mainly diagnosed in women of Asian origin and can occur in patients with Peutz-Jeghers syndrome. Although no clear grading system has been recommended in the WHO classification, it is likely that grading of adenocarcinomas of the uterine cervix will partly be based on the different patterns of invasion...

Important in angiogenesis, vascular endothelial growth factor (VEGF) acts as a biomarker in the growth of and prognosis for breast cancer. Evidence suggests that single nucleotide polymorphisms of VEGF such as +936C/T (rs3025039) effects VEGF levels; however, current studies on the association between +936C/T and breast cancer risk are inconsistent. This meta-analysis was conducted to reach a more precise conclusion about this association. PubMed was searched for case-control studies on the association between +936C/T levels and breast cancer risk...

Thrombosis is a common complication in cancer patients. Although the major inherited risk factors for thrombophilia are different between Asians and Caucasians, the main acquired risk factors that are associated with the development of venous thromboembolism (VTE) in Asians appear to be similar to those for Caucasians. Malignancy is the most important acquired risk factor for VTE in Asians. Recent studies have shown that the incidence of VTE is significant in Asian patients with cancer, particularly those in an advanced stage...

PURPOSE: Questions remain uncertainty regarding the gender differences in the relationship between type 2 diabetes (T2DM) and liver cancer risk. By considering several confounding factors, we aimed to identify this issue according to a meta-analysis of cohort studies. METHODS: We searched EMBASE and MEDLINE for studies on the association between T2DM and risk of liver cancer up to November 30, 2014. A random-effects model was performed to calculate summary relative risks (SRRs) with corresponding 95% confidence intervals (CIs)...

Metastasis of lung cancer to soft tissue is rare and patient outcomes are generally poor. There are no reports describing soft tissue metastasis in lung squamous cell carcinoma (SCC), in which gefitinib treatment was effective not only for the primary tumor but also the metastatic lesion. A 61-year-old Asian woman presented to our facility with pain and a mass in the brachium. An additional tumor was identified in the lung. As we suspected soft tissue metastasis of lung cancer, an incisional biopsy was performed, yielding a diagnosis of SCC...

Hypertension is one of the strongest risk factor for cardiovascular disease. Recently, accumulating evidence also indicates that hypertension has been linked with non-cardiovascular diseases including dementia, cancer, oral health diseases and so on. In general, elderly individuals tend to have multiple diseases as getting older. Preventing of hypertension is also benefit for other diseases.In the Hisayama Study, hypertension increased the risk of vascular dementia, but were not associated with an increased risk of Alzheimer disease, and that subjects with hypertension in midlife and normotension and hypertension in late-life increased risks of incident vascular dementia...

Obesity is a pan-endemic health problem in both developed and developing countries, in both western and eastern countries. It increases risk for many common diseases, including type 2 diabetes, dyslipidemia, hypertension, obstructive sleep apnea, heart disease, stroke, asthma, osteoarthritis, cancers and depression etc.. Although the incidence of obesity in Asia is relatively low, Asian patients tend to have similar incidence of obesity related metabolic syndrome at lower BMI level comparing to Caucasians because of central obesity...

INTRODUCTION: In the U.S., people of different races/ethnicities have differences in cancer incidence, mortality, survival, stage at diagnosis, and receipt of treatment, resulting in variances in cancer burden. The burden of cancer in 2011 was assessed by race/ethnicity for 24 cancers using disability-adjusted life years (DALYs). METHODS: In 2014-2015, DALYs and their two components were estimated (years of life lost [YLLs] and years lived with disability) by race/ethnicity using population-based cancer registry data collected in 2013, vital statistics, and literature reviews...

Considerable studies have investigated the associations between MDM4 gene polymorphisms and cancer risk recently, but with contradictory results. The aim of this meta-analysis was to evaluate the associations between MDM4 gene polymorphisms and cancer risk. Relevant studies were identified by a systematic search of PubMed, Embase, and CNKI databases. Crude odds ratios (ORs) and 95% confidence intervals (CIs) were used to describe the strength of the associations. Fifty-six studies published in 11 publications involving 18,910 cases and 51,609 controls were included in this meta-analysis...

BACKGROUND: Mucosal melanomas are rare, poorly understood neoplasms without a consensus standard of care. OBJECTIVE: We sought to define mucosal melanoma tumor characteristics and the racial/ethnic attributes of patients with mucosal melanomas. METHODS: We analyzed 130,920 cutaneous melanomas and 1919 mucosal melanomas recorded in the population-based California Cancer Registry from 1988 to 2013. RESULTS: Although only 1% of melanomas occurring in nonHispanic whites were mucosal, other racial/ethnic groups had a higher proportion of mucosal melanomas (15% for Asian/Pacific Islanders, 9% for nonHispanic blacks, and 4% for Hispanics)...

Molecular epidemiological research suggests that mouse double minute 4 (MDM4) polymorphisms may be associated with cancer susceptibility, but results remain controversial. To derive a more precise evaluation, we performed a PRISMA compliant meta-analysis focused on five single nucleotide polymorphisms (rs11801299, rs1380576, rs10900598, rs1563828, and rs4245739) of MDM4. Overall, 23 studies involving 22,218 cases and 55,033 controls were analyzed. The results showed that rs4245739 was significantly associated with a decreased cancer risk in the allelic (C vs...

Importance: Capecitabine is an oral cytotoxic chemotherapeutic commonly used across cancer subtypes. As with other oral medications though, it may suffer from drug interactions that could impair its absorption. Objective: To determine if gastric acid suppressants such as proton pump inhibitors (PPIs) may impair capecitabine efficacy. Design, Setting, and Participants: This secondary analysis of TRIO-013, a phase III randomized trial, compares capecitabine and oxaliplatin (CapeOx) with or without lapatinib in 545 patients with ERBB2/HER2-positive metastatic gastroesophageal cancer (GEC); patients were randomized 1:1 between CapeOx with or without lapatinib...

Esophageal squamous cell carcinoma (ESCC) is endemic in regions of sub-Saharan Africa (SSA), where it is the third most common cancer. Here, we describe whole-exome tumor/normal sequencing and RNA transcriptomic analysis of 59 patients with ESCC in Malawi. We observed similar genetic aberrations as reported in Asian and North American cohorts, including mutations of TP53, CDKN2A, NFE2L2, CHEK2, NOTCH1, FAT1, and FBXW7. Analyses for nonhuman sequences did not reveal evidence for infection with HPV or other occult pathogens...

BACKGROUND: Epidemiologic evidence on dietary carbohydrates and stroke risk remains controversial. Very few prospective cohort studies have been conducted in Asian populations, who usually consume a high-carbohydrate diet and have a high burden of stroke. OBJECTIVE: We examined dietary glycemic index (GI), glycemic load (GL), and intakes of refined and total carbohydrates in relation to risks of total, ischemic, and hemorrhagic stroke and stroke mortality. DESIGN: This study included 64,328 Chinese women, aged 40-70 y, with no history of cardiovascular disease, diabetes, or cancer...
