Risk-based Stratification of Salivary Gland Lesions on Cytology: An Institutional Experience.

Background & Objective: Fine needle aspiration cytology (FNAC) of salivary gland lesions is an accepted and useful diagnostic tool to differentiate between benign and malignant lesions. Majority of the neoplasms are benign, and specific diagnosis on cytology can be made in most of the cases. However, the utility is limited by the overlapping and heterogeneous morphological features of benign and malignant neoplasms.

Triple negative breast cancer in people of North East India: critical insights gained at a regional cancer centre.

Background: Breast cancer is a heterogeneous disease comprising of distinct biological subtypes with many targeted prognostic biomarkers having therapeutic implications. However, no specific targeted therapy for triple negative breast cancer has been discovered to date and hence further research is needed.

Aim: The aim and objectives of the present study were to examine the prevalence of triple negative breast cancer (TNBC) in North-East India and to compare the clinicopathological parameters in two study groups defined by immunohistochemistry (IHC) -"TNBC" and "Others".

Hybrid capture 2 assay based evaluation of high-risk HPV status in healthy women of north-east India.

Background: High risk HPV (HR-HPV) testing has been recommended as an effective tool along with cytology screening in identification of cervical intraepithelial lesions (CINs) and prevention of their progress towards invasive cervical cancer. The aim of this study was to assess the HR-HPV DNA status by Hybrid Capture 2 (HC2) assay in healthy asymptomatic women of North-East India.

Materials And Methods: This study examined cervical cell samples of forty three (n=43) healthy women by HC2 assay.

Nested multiplex PCR based detection of human papillomavirus in cervical carcinoma patients of North- East India.

Background: Persistent infection of one or more of about 15 high-risk human papillomaviruses (HR-HPVs), most commonly HPV types 16/18, has a significant role in cervical cancer initiation and progression. There are limited data available from north-east India about HPV prevalence though this region has high incidence rates of cervical cancer. The aim of this study was to investigate the HPV genotypes prevalent in cervical cancer patients of north-east India.

A novel single-port technique for transanal rectosigmoid resection and colorectal anastomosis on an ex vivo experimental model.

Background: In the context of natural orifice translumenal endoscopic surgery (NOTES), we developed a new set of rigid instruments according to the principles of transanal endoscopic microsurgery (TEM).These instruments are long, curved, and steerable by rotating two wheels near its handle. Our success in transvaginal cholecystectomy in human with these instruments motivated us to explore the feasibility of rectosigmoid resection through the anus.
