Oral cancer is one of the highly prevalent cancers worldwide and a leading cause of mortality in certain regions like South-Central Asia. It is a major public health problem. Late diagnosis, high mortality rates and morbidity are characteristics of the disease worldwide. For control of oral cancer an idea of the coverage of the same in the various regions is necessary. The estimated incidence, mortality and 5-year survival due to lip, oral cavity cancer in world is 3, 00, 373(2.1%), 1, 45, 328(1.8%) and 7, 02, 149(2...

Head and neck cancer (HNC) includes a diverse range of malignancies arising commonly from mucosal epithelia of the upper aerodigestive tract. Head and neck squamous cell carcinoma (HNSCC), the most common form of HNC, develops in the oral cavity, pharynx, and larynx and is associated with tobacco exposure, alcohol abuse, and infection with oncogenic viruses. Despite global advances in cancer care, HNSCC often presents with advanced disease and is associated with poor 5-year survival of ~50%. Genotyping tumor tissue to guide clinical decision-making is becoming commonplace in modern oncology, but in the management of HNSCC, tissue biopsies with cytopathology or histopathology remain the mainstay for diagnosis...

PURPOSE OF REVIEW: Prognosis of advanced oral squamous cell carcinoma remains a challenge for clinicians despite progress in its diagnosis and treatment over the past decades. In this review, we assessed clinicopathological factors and potential biomarkers along with their prognostic relevance in an attempt to develop optimal treatment strategies for these patients. RECENT FINDINGS: In addition to several pathologic factors that have been proposed to improve prognostic stratification and treatment planning in the eighth edition of the American Joint Committee staging manual on cancer, we reviewed some other imaging and clinicopathological parameters demonstrated to be closely associated with patient prognosis, along with the biomarkers related to novel target or immune therapy...

OBJECTIVES: Conditional relative survival (CRS) describes the survival chance of patients who have already survived for a certain period of time after diagnosis and treatment of cancer. Thus, CRS can complement the conventional 5-year relative survival, which does not consider the time patients have survived after their diagnosis. This study aimed to assess the 5-year CRS among Korean patients with oral cancer and the related risk factors. MATERIALS AND METHODS: We identified 15,329 oral cavity cancer cases with a diagnosis between 1993 and 2013 in the Korea Central Cancer Registry...

OBJECTIVES: Mucoepidermoid carcinoma (MEC) is an uncommon malignancy that most commonly occurs in the parotid gland followed by the minor salivary glands of the upper aerodigestive tract, most notably in the oral cavity (OC) and oropharynx (OP). Because of its rarity, few studies have been performed that are specific to MEC within the OC and OP. The objective of this study is to describe the tumor characteristics and prognostic features for MEC of the OC and OP. MATERIALS AND METHODS: The National Cancer Database (NCDB) was used for this study...

BACKGROUND: Fusobacterium nucleatum is a gram-negative anaerobic species residing in the oral cavity and implicated in several inflammatory processes in the human body. Although F. nucleatum abundance is increased in inflammatory bowel disease subjects and is prevalent in colorectal cancer patients, the causal role of the bacterium in gastrointestinal disorders and the mechanistic details of host cell functions subversion are not fully understood. RESULTS: We devised a computational strategy to identify putative secreted F...

Human papillomaviruses (HPVs) are double-stranded DNA (dsDNA) tumor viruses that are causally associated with human cancers of the anogenital tract, skin, and oral cavity. Despite the availability of prophylactic vaccines, HPVs remain a major global health issue due to inadequate vaccine availability and vaccination coverage. The HPV life cycle is established and completed in the terminally differentiating stratified epithelia, and decades of research using in vitro organotypic raft cultures and in vivo genetically engineered mouse models have contributed to our understanding of the interactions between HPVs and the epithelium...

Oral cavity squamous cell carcinoma is the most common type of head and neck carcinoma. Its incidence is increasing worldwide, and it is associated with major morbidity and mortality. It is often unclear which patients have aggressive, treatment refractory tumors vs those whose tumors will be more responsive to treatment. Better identification of patients with high- vs low-risk cancers could help provide more tailored treatment approaches and could improve survival rates while decreasing treatment-related morbidity...

Cervix carcinoma is the second commonest condition in women under 50 years of age and third after breast and oral cavity cancers across all age groups. Though a preventable disease, the mortality rate is very high because it is an ignored ailment in Pakistan in terms of screening, prevention and vaccination. More than 70% of cancer patients report with very advanced stage of malignancy and this is the cause of the high rate of mortality in Pakistan. We covered studies cited during the previous 11 years (2005-2015) that reviewed many aspects of cervical cancer in Pakistan, including epidemiology, risk factors, screening test and their barriers, clinical presentation and prevention...

PURPOSE: The purpose of the paper is to assess the influence of marital status on conditional relative survival of cancer according to sex. METHODS: Analyses involved 779,978 males and 1,032,868 females diagnosed with 1 of 13 cancer types between 2000 and 2008, and followed through 2013. Data are from the Surveillance, Epidemiology, and End Results (SEER) Program. Regression models were adjusted for age, sex, race, and tumor stage. RESULTS: Five-year relative survival conditional on years already survived is higher among married patients with less lethal cancers (oral cavity and pharynx, colon and rectum, breast, urinary bladder, kidney and renal pelvis, melanoma of the skin, thyroid, lymphoma)...

The five-year survival rate for patients with oral cancer remains low, in part because diagnosis often occurs at a late stage. Early and accurate identification of oral high-grade dysplasia and cancer can help improve patient outcomes. Multi-modal optical imaging is an adjunctive diagnostic technique in which autofluorescence imaging is used to identify high-risk regions within the oral cavity, followed by high resolution microendoscopy to confirm or rule out the presence of neoplasia. Multi-modal optical images were obtained from 206 sites in 100 patients...

Very little data exist on the incidence and burden of cancer in the individual Caribbean countries. Some data are available for larger areas, reported under a bigger geographical region; Latin America and the Caribbean, but many of the individual countries are not included. One of the main reasons is a lack of official cancer registries. Data are usually collected from hospital records or private physician records, and since it is not in an official registry, these data are not always accessible for inclusion in databases such as SEER and GLOBOCAN...
