There is an increasingly growing interest world-wide for the genomics, transcriptomics and proteomics of saliva and the oral cavity, since they provide a non-invasive source of unprecedently rich genetic information. The complexity of oral systems biology goes much beyond the human genome, transcriptome and proteome revealed by oral mucosal cells, gingival crevicular fluid, and saliva, and incl...
Oral cancer holds the eighth position in the cancer incidence ranking worldwide and is the 11th most common form of cancer in Malaysia (Lim et al., 2008; Moore et al., 2009). Of all head and neck cancers, Oral Squamous Cell Carcinoma (OSCC) is the most common malignant epithelial neoplasm of oral cavity (90%); they represent approximately 5% in men and 2 % in women considering all malignancies ...
Tumoral cavity formation is a characteristic phenomenon reported in anti-angiogenic therapy in lung lesions. A 57-year-old male with multiple pulmonary metastases from colorectal cancer treated with an oral tyrosine kinase inhibitor, regorafenib, exhibited a characteristic cavity formation after the first two cycles. The decrease in the size of tumors was calculated as 38%, and there were assoc...
PURPOSE Squamous cell carcinoma of the oral cavity is one of the most common human neoplasms, and prevention of these carcinomas requires a better understanding of the carcinogenesis process and a model system in which cancer chemoprevention agents can be tested. We have developed a mouse model using the carcinogen 4-nitroquinoline 1-oxide (4-NQO) in the drinking water to induce tumorigenesis i...
In 2020, cancers of the breast, lip and oral cavity cervix were three most common in India.(1) The national programme for prevention control cancer, diabetes, cardiovascular diseases stroke (NPCDCS) recommends a population-based screening identifying pre-cancerous lesions early detection these by front line health workers.(2) Data about cancer has been included latest National Family Health Sur...
Metastatic tumors of the oral cavity are rare in occurrence. Renal cell carcinoma (RCC) metastasizes to organs head and neck 12–16% cases. RCC metastases tongue uncommon. A total 63 cases kidney cancer metastasizing have been reported literature. We report a clinical case metastasis skin lower eyelid (as initial manifestation disease) (11 months after diagnosis) one patient with metastatic canc...
In the present study we examined the release of the soluble form of TRAIL by neutrophils (PMN) derived from patients with oral cavity cancer. Simultaneously, we estimated the ability of PMNs of these patients to release the soluble form of DR5 receptor, a natural regulatory protein of TRAIL. The obtained results were confronted with the serum levels of sTRAIL and sDR5. The cells were isolated f...
The incidence of occult cervical metastasis in oral cavity cancer, even in early stages, is significant, necessitating elective treatment of the neck in a majority of cases. There is no method of imaging or other examination that will detect microscopic foci of metastatic disease in cervical lymph nodes. Immunohistochemical and molecular analysis of neck specimens reveals the incidence of occul...
Head and neck cancers, categories lip, oral cavity, pharynx and larynx are placed amongst the top ten malignancies globally. The cancers have a similar epidemiology, risk factors, morphology, and control measures. The geographical variations in incidence are indicative of the global differences in the prevalence of risk factors. The present study was conducted with the objective of reviewing de...
BACKGROUND Only a few studies have explored the relation between coffee and tea intake and head and neck cancers, with inconsistent results. METHODS We pooled individual-level data from nine case-control studies of head and neck cancers, including 5,139 cases and 9,028 controls. Logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (95% CI), adjusting for pote...
