A prospective cohort study comparing efficacy of 1 dose of quadrivalent human papillomavirus vaccine to 2 and 3 doses at an average follow up of 12 years postvaccination.

Background: While recommending a human papillomavirus (HPV) single-dose vaccination schedule in 2022, the World Health Organization highlighted the need for long-term follow-up studies to monitor waning of protection. We report on vaccine efficacy against HPV infections in 1-, 2-, and 3-dose schedules and protection against cervical precancers at a median follow-up of 12 years postvaccination.

Methods: This randomized multicenter study in India was originally designed to vaccinate unmarried girls aged 10-18 years with either 2 or 3 doses of quadrivalent HPV vaccine.

Evaluating different samples & techniques for hr-HPV DNA genotyping to improve the efficiency of risk profiling for oral & cervical cancers in Sikkim, India.

Background & objectives Oral and genital HPV infection in men may be a source of cervical diseases in their women partners as well as disease in themselves. This study aimed to evaluate and compare the performance of Hybrid Capture 2 (HC2) in physician-collected cervical samples and qPCR in self-collected urine and oral gargle samples of women and men, respectively, for hr-HPV infection status and genotyping. Methods One thousand and two hundred biological samples were collected from 200 women (urine, oral gargle, and cervical smear) and 200 men (urine and oral gargle) visiting a referral hospital in the remote Himalayan State of Sikkim.

Questionnaire-Based Study on the Knowledge of Cervical Cancer and Attitude and Perception Toward Self-Sampling Method of Screening, Among Women in Sikkim, India.

Background: Cervical cancer (CC) is the second most common cancer among women in India and in Sikkim. Screening helps in prevention and early detection of the disease; however, pelvic examination for smear collection is not preferred by many. Self-sampling method can be a good alternative for collection of smears, thus increasing screening uptake.

Accuracy of Frozen Section and Clinical/Radiological Diagnosis with Final Histopathology of Pelvic Masses in a Teaching Institute with a Non-oncology Setup, in Northeast India.

Background: Frozen section (FS) is an important decision making intraoperative tool in a non-oncology center especially in a region where women are often "lost to followup".

Objectives: Evaluate the use of FS in non-oncology setup for ovarian and uterine masses.

Methods: A retrospective analysis of women who had undergone surgery with frozen section for large abdominopelvic masses at Central Referral Hospital, Sikkim, India, from July 2017 to July 2021.

Advances in HPV Screening Tests for Cervical Cancer-A Review.

HPV is responsible for almost all cases of cervical cancer which in turn is one of the common causes of death among female genital malignancies. Cervical cancer being a preventable disease, screening plays a vital role in its reduction. In this era of advanced health care system and technologies this cancer is still in the increasing trend, especially in the Low and Middle Income Countries, which reflects the poor coverage of women for screening.

Evaluation of CA-125 as an Indicator of Imaging During Follow-up of Carcinoma Ovary: Original Research.

Background: Women with response to primary treatment for advanced ovarian cancer are said to have progression if CA125 increases more than double the upper normal limit (70 IU/L) on follow-up. It was, however, noted that large section of women with CA125 > 35 IU/L had disease on imaging.

Objective: To compare values of CA125 rise at which radiological recurrence can be detected.

KAP Study on HIV/AIDS Among Antenatal Women Attending Central Referral Hospital of North East India.

Background: This study was conducted to determine whether antenatal mothers in Sikkim have adequate knowledge about awareness, attitude, and preventive practices regarding HIV infection.

Methods: Cross-sectional study using structured questionnaire. 220 Antenatal mothers attending the outpatient department of Central Referral Hospital of Sikkim were taken for the study for a period of 1 year from April 2011 to April 2012.
