IJERPH, Vol. 18, Pages 12406: Cervical Visual Inspection with Acetic Acid (VIA) and Oncogenic Human Papillomavirus Screening in Rural Indigenous Guatemalan Women: Time to Rethink VIA

This study compared VIA sensitivity and specificity in rural indigenous Guatemalan communities, to that of oncogenic human papillomavirus (HPV) testing for detection of precancerous changes, using cytology as the reference standard. Between 3–8 September 2017, trained nurses examined 222 women aged 23–58 years with VIA. Specimens for liquid-based cytology and HPV testing were obtained prior to VIA with a cytobrush and transported in PreservCyt to a US clinical laboratory. VIA and HPV test sensitivities were assessed as proportions of women with abnormal cytology that had abnormal VIA or HPV results, respectively, and specificities, as proportions with normal cytology with normal VIA or negative HPV tests. Of 222 women, 18 (8.1%) had abnormal cytology (1 carcinoma in a participant who received VIA-based cryotherapy in 2015, 4 high- and 5 low-grade squamous intraepithelial lesions, and 8 atypical squamous cells of undetermined significance (ASCUS)). Excluding ASCUS, sensitivities of VIA and HPV were 20.0% and 100%, respectively. VIA-based screening may not be acceptable for detecting precancerous lesions, and field cryotherapy for preventing malignancy. The World Health Organization recommended in 2021 “…using HPV DNA detection as the primary screening test rather than VIA or cytology.”

Oncol Lett. 2022 Feb;23(2):71. doi: 10.3892/ol.2022.13191. Epub 2022 Jan 5.ABSTRACTThe EGFR is a protein that belongs to the ErbB family of tyrosine kinase receptors. The EGFR is often overexpressed in human carcinomas. Amplification of the EGFR gene and mutations in the EGFR tyrosine kinase domain occur in patients with cancer. In cervical cancer, the expression level of the EGFR protein appears to directly associate with human papillomavirus infection. Our previous research demonstrated that in the cervical cancer cell lines, CALO and INBL, the EGFR is non-phosphorylated. The aim of the current study was to analyze the c...

Has the HPV immunization program been effective? The human papillomavirus (HPV) immunization program was introduced to UK in 2008, focusing on 12-13 year old girls, initially with a catch up program for 14-18 year old girls between 2008 and 2010. Has there been an impact of cervical carcinoma in situ? Falcaro M et al [Lancet 2021; 398(10316):2084-2092. doi.org/10.1016/S0140-6736(21)02178-4] have reported the results of an observational study looking at data from a total of 13·7 million-years of follow-up of women aged 20 years to younger than 30 years. They have examined the grade 3 cervical intraepithelial neoplasi...

Conclusions Clinicians need be aware that women with vHSIL and VSCC comprise one of the highest-risk groups for ASCC. Inquiring suggestive symptoms of ASCC and a digital anorectal examination can help in the early detection of this type of cancer.

CONCLUSION: Minimally invasive surgery is being introduced for the treatment of early-stage cervical cancer. However, the number of eligible cases should be expanded in a phased manner, based on an objective evaluation of surgical outcomes at the facilities. Omics analysis may be useful to develop a new treatment for human papillomavirus nonrelated cervical cancer, represented by gastric mucinous carcinoma.PMID:34908207 | DOI:10.1111/jog.15112

Conclusions: The present study revealed highly oncogenic HPV-18 alone or in combination with multiple infections of high-risk genotypes – 31, 33, and 35 – in the rural women of Lucknow, North India. Since HPV vaccine currently available in India is for HPV-16 and HPV-18 combined, efforts should be made to make region-specific vaccine according to their prevalence in that particular state of the country to provide effective HPV vaccination.

In conclusion, this study showed that PGK1 expression might serve as a prognostic biomarker in cervical cancer. Its upregulation contributes to enhanced aerobic glycolysis, migration, and invasion of CESC cells. HPV16 E6/E7 stabilizes PGK1 protein by reducing its poly-ubiquitination.

In conclusion, this study enhances our understanding of HPV-induced carcinogenesis in PSCC, which may not only rely on the E6/E7 oncogenes, but mat also affect the expression of critical genes and thus activate oncogenic pathways.

We present here a 73-year-old female with a prior human papillomavirus (HPV) + SCC of the cervix that had metastasized to her peri-aortic lymph nodes. Eight years after diagnosis and treatment, she returned with a hypermetabolic supraclavicular lymph node and new left-sided neck mass. Biopsy of the neck mass revealed invasive SCC positive for high-risk HPV genotype. The presence of high-risk HPV genotypes in both the cervix and supraclavicular lymph node, without evidence of second primary tumor, implies that the neck mass is a delayed metastasis of the patient's previous cervical cancer. This marks the second recorded cas...
