Many biologic products have improved the outcomes of cancer patients, but the costs can substantially burden healthcare systems. Biosimilar products can potentially reduce drug costs and increase patient access to beneficial treatments. Approval of a biosimilar product relies on the demonstration of "comparability" or "no clinically meaningful differences" as compared to its reference biologic product. Biosimilar products for erythropoietin, granulocyte colony-stimulating factor, trastuzumab, and rituximab are already available, and the regulatory processes in various countries are constantly evolving...

As a standard way for prevention and early detection of colorectal cancer (CRC), colonoscopy has been used for CRC screening in the United States for more than one decade. An article entitled "Assessing Colorectal Cancer Screening Adherence of Medicare Fee-For-Service Beneficiaries Age 76 to 95 Years" recently published at the Journal of Oncology Practice reports the trends in overuse of CRC screening services among average-risk elderly populations at the age of 76-95 years. Several reasons for overusing colonoscopy have been postulated, and some strategies for reducing overuse of CRC screening services have also been proposed...

This year is the 150th anniversary of the birth of Sun Yat-sen (November 12, 1866) and the 91st year following his death (March 12, 1925). It generally has been believed that the cause of his death was "liver cancer." However, as indicated in the official autopsy report, dated March 13, 1925, of the Peking Union Medical College Hospital (PUMCH) in Beijing, the cause of his death in reality was an adenocarcinoma of the gallbladder with direct extension to the liver and diaphragm as well as widespread metastases to the peritoneal cavity...

Gastric cancer ranks the fourth most prevalent malignancy yet it is the second leading cause of cancer-related death. Every year, gastric cancer adds nearly 1 million new cancer cases, and 723,000 or 10% of cancer deaths to the global cancer burden. Approximately, 405,000 or 43% of the new cases and 325,000 or 45% of the deaths are in China, making gastric cancer a particularly challenging malignancy. This thematic series discusses the molecular classifications of gastric cancer by the Cancer Genome Atlas (TCGA) and the Asian Cancer Research Group (ACRG) as well as the implications in personalized therapeutic choices; discusses the evolution of gastric surgery and presents perspectives on surgical techniques in treating gastric cancer; and reviews current and emerging targeted agents as well as immunotherapies in treating gastric cancer...

Gastric (including gastroesophageal junction) cancer is the third leading cause of cancer-related death in the world. In China, an estimated 420,000 patients were diagnosed with gastric cancer in 2011, ranking this malignancy the second most prevalent cancer type and resulting in near 300,000 deaths. The treatment landscape of gastric cancer has evolved in recent years. Although systemic chemotherapy is still the mainstay treatment of metastatic disease, the introduction of agents targeting human epidermal growth factor receptor 2 and vascular endothelial growth factor/vascular endothelia growth factor receptor has brought this disease into the molecular and personalized medicine era...

BACKGROUND: Von Hippel-Lindau (VHL) syndrome is a dominantly inherited multisystem cancer syndrome caused by a heterozygous mutation in the VHL tumor suppressor gene. Previous studies suggested that similar populations of Caucasian and Japanese patients have similar genotype or phenotype characteristics. In this comprehensive study of East Asian patients, we investigated the genetic and clinical characteristics of patients with VHL syndrome. METHODS: To create a registry of clinical characteristics and mutations reported in East Asian patients with VHL syndrome, we conducted a comprehensive review of English language and non-English language articles identified through a literature search...

BACKGROUND: Serum immunoglobulin A antibodies against Epstein-Barr virus (EBV), viral capsid antigen (VCA-IgA) and early antigen (EA-IgA), are used to screen for nasopharyngeal carcinoma (NPC) in endemic areas. However, their routine use has been questioned because of a lack of specificity. This study aimed to determine the distributions of different subtypes of antibody and to illustrate how the natural variation patterns affect the specificity of screening in non-NPC participants. METHODS: The distribution of baseline VCA-IgA was analyzed between sexes and across 10-year age groups in 18,286 non-NPC participants using Chi square tests...

BACKGROUND: Esophageal squamous cell carcinoma (ESCC) is a leading cause of cancer death worldwide and is characterized by numerous genetic mutations. TNM staging is not sufficient for predicting patient outcomes. Additionally, ESCC shows poor responsiveness to chemotherapy and radiation. Thus, there is an urgent need to find efficient therapy targets. Previous ESCC high-throughput genomic studies have lacked intensive survival analysis, particularly for copy number variation (CNV) and the genes involved...

BACKGROUND: MicroRNA (miRNA) polymorphisms may alter miRNA-related processes, and they likely contribute to cancer susceptibility. Various studies have investigated the associations between genetic variants in several key miRNAs and the risk of human cancers; however, few studies have focused on head and neck squamous cell carcinoma (HNSCC) risk. This study aimed to evaluate the associations between several key miRNA polymorphisms and HNSCC risk in a Chinese population. METHODS: In this study, we genotyped five common single-nucleotide polymorphisms (SNPs) in several key miRNAs (miR-149 rs2292832, miR-146a rs2910164, miR-605 rs2043556, miR-608 rs4919510, and miR-196a2 rs11614913) and evaluated the associations between these SNPs and HNSCC risk according to cancer site with a case-control study including 576 cases and 1552 controls, which were matched by age and sex in a Chinese population...

BACKGROUND: Clinical trials continue to be the gold standard for determining the efficacy of novel cancer treatments, but they may also expose participants to the potential risks of unpredictable or severe toxicities. The development of validated tools that better inform patients of the benefits and risks associated with clinical trial participation can facilitate the informed consent process. The design and validation of such instruments are strengthened when we leverage the power of pooled data analysis for cancer outcomes research...
