ABSTRACT Introduction Cervical cancer is the second most common cancer in women worldwide, and it is the principal cancer of women in most developing countries, where 80% of cases occur. This disease is preventable by screening and treatment of preinvasive condition. All sexually active women are at risk of acquiring a human papillomavirus (HPV) infection that may lead to cervical cancer in the future. Cervical cancer is a preventable disease as the different screening, diagnostic, and therapeutic procedures are effective. The screening procedures are visual inspection of cervix with acetic acid (VIA), Pap smear, colposcopy, and HPV deoxyribonucleic acid test. Among them, colposcopy is effective in screening, taking colposcopy-directed biopsy as well as treatment of cervical intraepithelial neoplasia (CIN), such as cold coagulation, cryotherapy, and loop electro-surgical excision procedure. Hence, there is an obvious need to subject the women with VIA-positive report to colposcopy and directed biopsy. This study is done to evaluate the role of colposcopy in evaluation of VIA-positive cases. Objective Colposcopic evaluation of VIA-positive cases and detection of precancerous lesion of cervix for early management. Materials and methods This was a cross-sectional study done among married female patient aged 22 to 65 years, who had VIA-positive report, and attending the colposcopy clinic in the Department of Obstetrics and Gynecology of Sir Salimullah Medical College and Mitford Hospital from January 2014 to December 2016. Colposcopy-directed punch biopsy was taken from the abnormal colposcopic appearance and specimen sent for histopathological examination. Results Out of 97 cases, all had VIA-positive acetowhite areas. But colposcopy revealed that 76.29% had CIN and invasive lesions, while 23.71% had either normal or inflammatory lesions. Colposcopy-directed punch biopsy revealed that 59.79% cases had positive lesions like CIN or invasive carcinoma and 40.21% had neither CIN nor invasive lesions. Among positive lesions, about 34.02% had CIN I, 3.09% had CIN II, 0% had CIN III, and 22.68% had invasive carcinoma. In this study, sensitivity and specificity of colposcopy examination were found 94.83 and 51.28% respectively. Conclusion Cervical cancer presents as major cause of morbidity and mortality, especially in developing countries like Bangladesh. In developing countries, the various screening programs are implemented for its early detection and treatment. It is evident that colposcopy plays a very important role in early diagnosis and treatment of preinvasive and early invasive carcinoma of cervix. So wide use of colposcopy in screening program of Bangladesh can reduce many young women's morbidity and mortality. How to cite this article Kasem SB, Razzaque SA, Adiba R, Anika S, Begum F.

Background: Cervical cancer induced by infection with human papillomavirus (HPV) remains a leading cause of mortality for women worldwide although preventive vaccines and early diagnosis have reduced morbidity and mortality. Advanced cervical cancer can only be treated with either chemotherapy or radiotherapy but outcomes are poor. The median survival for advanced cervical cancer patients is only 16.8 months. Methods: We undertook a structural search of peer-reviewed published studies based on 1). Characteristics of programmed cell death ligand-1/programmed cell death-1(PD-L1/PD-1) expression in cervical cancer and upstream regulatory signals of PD-L1/PD-1 expression, 2). The role of the PD-L1/PD-1 axis in cervical carcinogenesis induced by HPV infection and 3). Whether the PD-L1/PD-1 axis has emerged as a potential target for cervical cancer therapies. Results: One hundred and twenty-six published papers were included in the review, demonstrating that expression of PD-L1/PD-1 is associated with HPV-caused cancer, especially with HPV 16 and 18 which account for approximately 70% of cervical cancer cases. HPV E5/E6/E7 oncogenes activate multiple signaling pathways including PI3K/AKT, MAPK, hypoxia-inducible factor 1α, STAT3/NF-kB and MicroRNAs, which regulate PD-L1/PD-1 axis to promote HPV-induced cervical carcinogenesis. The PD-L1/PD-1 axis plays a crucial role in immune escape of cervical cancer through inhibition of host immune response. creating an "immune-privileged" site for initial viral infection and subsequent adaptive immune resistance, which provides a rationale for therapeutic blockade of this axis in HPV-positive cancers. Currently, Phase I/II clinical trials evaluating the effects of PD-L1/PD-1 targeted therapies are in progress for cervical carcinoma, which provide an important opportunity for the application of anti-PD-L1/anti-PD-1 antibodies in cervical cancer treatment. Conclusion: Recent research developments have led to an entirely new class of drugs using antibodies against the PD-L1/PD-1 thus promoting the body’s immune system to fight the cancer. The expression and roles of the PD-L1/ PD-1 axis in the progression of cervical cancer provide great potential for using PD-L1/PD-1 antibodies as a targeted cancer therapy.

: Cervical cancer (CC) is the fourth leading cancer in women in the age group 15-44 globally. Experimental as well as epidemiological studies identified that type16 and 18 HPV cause 70% of precancerous cervical lesions as well as cervical cancer worldwide by bringing about genetic as well as epigenetic changes in the host genome. The insertion of the HPV genome triggers various defense mechanisms including the silencing of tumor suppressor genes as well as activation of oncogenes associated with cancer metastatic pathway. E6 and E7 are small oncoproteins consisting of 150 and 100 amino acids respectively. These oncoproteins affect the regulation of the host cell cycle by interfering with p53 and pRb. Further these oncoproteins adversely affect the normal functions of the host cell by binding to their signaling proteins. Recent studies demonstrated that E6 and E7 oncoproteins are potential targets for CC. Therefore, this review discusses the role of E6 and E7 oncoproteins in metastasis and drug resistance as well as their regulation, early oncogene mediated signaling pathways. This review also uncovers the recent updates on molecular mechanisms of E6 and E7 mediated phytotherapy, gene therapy, immune therapy, and vaccine strategies as well as diagnosis through precision testing. Therefore, understanding the potential role of E6/E7 in metastasis and drug resistance along with targeted treatment, vaccine, and precision diagnostic strategies could be useful for the prevention and treatment of cervical cancer.
