Screening Women at High Risk for Cervical Cancer: Special Groups of Women Who Require More Frequent Screening

Warangalone Induces Apoptosis in HeLa Cells via Mitochondria-Mediated Endogenous Pathway

Cervical cancer as one of the major malignant tumors seriously threatens women's health. More than 270,000 women die of cervical cancer each year. Warangalone is an isoflavone compound isolated from Cudrania tricuspidata with excellent antitumor activity. In this research, we investigated the molecular mechanism of warangalone-induced apoptosis in HeLa cells. The results show that warangalone can selectively and effectively inhibit HeLa cells proliferation. Warangalone can effectively inhibit the invasion and migration of HeLa cells. Furthermore, warangalone was confirmed to activate p53 and mitogen-activated protein kinase (MAPK) family signaling pathways to cause apoptosis. In this case, the expression of the B-cell lymphoma-2 (Bcl-2) family is regulated, and caspase-3 is eventually cleaved, finally triggering the mitochondrial apoptosis. In conclusion, warangalone can induce HeLa cells apoptosis via a mitochondria-mediated endogenous pathway, which represented the potential therapeutic effect of warangalone on cervical cancer.

Squamous Carcinoma of the Cervix in a 15-Year-Old with Congenital HIV: A Case Report

BACKGROUND

Human papillomavirus (HPV) is the most prevalent sexually transmitted infection (STI) worldwide. Immunocompetent hosts have intact defense mechanisms to prevent HPV infection, but immunocompromised patients are at higher risk for complications, including HPV-related cancers. Most of these cancers originate from high-risk HPV strains in sexually active patients.

CASE

Here we present a case of an immunocompromised adolescent who developed cervical cancer despite no prior sexual activity and only ever having had low-risk type HPV on biopsy.

SUMMARY AND CONCLUSIONS

To our knowledge, this is the first case report of a cervical cancer arising from a low-risk HPV strain in an immunocompromised, non-sexually active adolescent. This case highlights the importance of preventive and screening mechanisms in immunocompromised populations, as they are have a higher probability of HPV-related complications, even in the absence of traditional risk factors.

Repurposing Individualized Nutritional Intervention as a Therapeutic Component to Prevent the Adverse Effects of Radiotherapy in Patients With Cervical Cancer

Worldwide, cervical cancer was the fourth leading cause of cancer death among women, while in Mexico was the second cause (5.28%). Cancer patients receiving chemotherapy and radiotherapy have a high risk of malnutrition secondary to the disease and treatment, affects the patient's overall, with adverse effects on gastrointestinal symptoms. These use affects the medical therapy. The aim of the present study was to evaluate the benefits on individualized nutritional therapy on decrease weight loss and gastrointestinal adverse effects and to consider these outcomes in pharmacology research, especially in repurposing drugs. We conducted a longitudinal design with two comparation groups with medical diagnosis of cervical cancer and received radiotherapy weekly, 1) the intervention group (nutritional intervention and counseling -INC-) with 20 participants and 2) control group (retrospective cohort -CG-) with 9 participants. Weekly body composition, dietary intake, adverse effects (gastrointestinal symptoms), glucose, hemoglobin, and blood pressure were analyzed during 4 to 5 weeks. Both groups had weight loss weekly (p = 0.013 and p = 0.043 respectively) but the CG vs INC presented loss fat-free mass ≥500g in 67 and of 37% respectively. By the end of the intervention a 25% of the INC group had <10 g/dL of hemoglobin vs 60% for the CG. To compare the dietary intake of vitamins (A and folic acid), fiber (p = 0.006), iron (p = 0.03) and energy (mainly carbohydrates) (p = 0.04) were according to the recommendations in INC group (p>0.05). The number needed to treat was 4 (95% CI, 2 to 13). The nutritional intervention and counseling weekly during radiotherapy in cervical cancer to maintain/improve muscle mass, hemoglobin, and dietary intake above 70% of the recommendations for INC group compared to the evidence. Adequate nutritional status was maintained and decrease the rate of complications, mainly gastrointestinal symptoms, in INC group. The efficacy of drug repurposing can improve through individualized nutritional therapy for preventing adverse effects of radiotherapy in patients with cervical cancer.

Cervical Cancer Screening in Immunocompromised Women

In the context of changing recommendations for cervical cancer screening, differing recommendations in each province, and a lack of guidance for cervical screening of immunocompromised women, this article provides specific recommendations for cervical cancer screening of immunocompromised women in Canada.

Comparison of the Cepheid Xpert HPV test and the HC2 High-Risk HPV DNA Test for detection of high-risk HPV infection in cervical smear samples in SurePath preservative fluid

Purpose. Cytological and histological cervical screening methods for human papillomavirus may be subjective. Current guidelines recommend the use of direct human papillomavirus screening by molecular methods in conjunction with cytology for the detection of high-risk human papillomavirus types with carcinogenic potential. In this study, we compared the performance of the molecular Cepheid Xpert HPV test to the FDA-approved HC2 High-Risk HPV DNA Test on samples from patients presenting for cervical screening, regardless of the cytology results, in which cervical cell samples were originally collected for Papanicolaou (Pap) smear specimens in Becton Dickinson (BD) SurePath preservative fluid.Methodology. Cervical cells were obtained for Pap smear specimens from 343 women attending Qatif Central Hospital in Saudi Arabia for cervical cancer screening using a Cytobrush Plus GT and immersed in BD SurePath preservative fluid in BD SurePath collection vials. The study was carried out between December 2015 and July 2016.Results. The Xpert HPV test was positive in 27 (7.9 %) of the samples. The HC2 High-Risk HPV DNA Test was positive in 32 (9.3 %) of the samples. The most common HPV types according to the Xpert HPV test were HPV other types, either alone (n=15) or in combination with HPV16 (n=3). The overall concordance rate between the tests was 98.5 %. The positive concordance was 84.4 %.Conclusion. The Xpert HPV test is convenient to use on cervical cell samples collected for Pap smear specimens in BD SurePath preservative fluid within an hour and is a viable alternative to the HC2 High-Risk HPV DNA Test for HPV testing.
