To evaluate and compare expression of VEGF in patients of premalignant lesions and squamous cell carcinoma of oral cavity. The cross sectional observational study is undertaken at the department of otorhionolaryngology and pathology, PGIMER and Dr RML Hospital, New Delhi,from 1st Nov 2017 to 31st March 2019,with a sample size of 30 cases each of premalignant lesions and oral squamous cell carcinoma immunohistochemistry by polymer method. In the participants with oral SCC, VEGF expression of Score 1 was observed in verrucous and well differentiated tumor, Score 2 in moderately differentiated SCC & Score 3 in poorly differentiated SCC with a value of 0.0001. The observed difference and value of proportion p, is statically significant. In this study we concluded that VEGF expression increases as the lesion progresses from premalignant lesions to oral squamous cell carcinoma and is strongly associated with lymph node status (N-staging). Thus, VEGF can be a target in chemotherapy and its therapeutic implications in the HNSCC needs further research. 1A: Systematic review of randomized control trials.

Risk-based triage strategy by extended HPV genotyping for women with ASC-US cytology.

Objective: We attempted to evaluate the immediate high-grade squamous intraepithelial lesion-cervical intraepithelial neoplasia grade 2/3 or worse (HSIL-CIN2+/3+, hereafter referred to as CIN2+/3+) risk of specific human papillomavirus (HPV) genotype and form the precise risk-based triage strategy for atypical squamous cells of undetermined significance (ASC-US) women.
Methods: The clinical data of ASC-US women who underwent HPV genotyping testing and colposcopy were retrospectively reviewed. The distribution and CIN2+/3+ risks of specific HPV genotype were assessed by three approaches.

Dentistry still faces difficulties in diagnosing oral precancer and cancer, especially when it comes to early phase changes or disease detection, evaluation, and treatment. In essence, oral lumenography is the process of identifying oral lesions using a chemiluminescent light source and a toluidine blue labeling system. Since neoplastic epithelial cells have a changed nuclear-cytoplasmic ratio, acetic acid dehydration brings out this nuclear density and gives the tissue an "acetowhite" look.

Importance: As US health care systems shift to human papillomavirus (HPV)-based cervical cancer screening, more patients are receiving positive high-risk non-16/18 genotype HPV results and negative for intraepithelial lesion or malignancy (NILM) cytological findings. Risk-based management guidelines recommend 2 consecutive negative annual results to return to routine screening.
Objective: To quantify patterns of surveillance testing and associated outcomes for patients after an HPV-positive results and NILM cytologic findings.
Background: Colorectal cancer (CRC) claims 900,000 lives per year. Colonoscopy offers reliable detection, but with low patient adherence rates. To significantly reduce CRC incidence and mortality, a more convenient screening measure for advanced precancerous lesions (APL) and CRC is urgently needed.

Tumor-specific HLA class I expression is required for cytotoxic T-cell elimination of cancer cells expressing tumor-associated or neo-antigens. Cancers downregulate antigen presentation to avoid adaptive immunity. The highly polymorphic nature of the genes encoding these proteins, coupled with quaternary-structure changes after formalin fixation, complicate detection by immunohistochemistry.
