“…Nevertheless, we only identified one related study in a literature search. Perisic et al reported that the use of Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14 could decrease the presence of unsatisfactory and/or borderline satisfactory cytological findings and thus provide a more reliable cytological diagnosis [26]. In our hospital, the annual Pap smear unsatisfactory rate is around 2.5%, however in the present study the rate was as high as 7.44%.…”

Background Probiotics has been shown to be effective in reducing vaginal colonization of pathogenic organisms. The aim of this study was to investigate the influence of probiotic strains Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14 on genital high-risk human papilloma virus (HR-HPV) clearance and quality of cervical smear. Methods This was a randomized, double-blinded, placebo-controlled trial. Women with genital HR-HPV infection were randomized into study and control groups. A probiotic or placebo preparation was administered orally (one capsule daily) until negative HR-HPV testing. A cervical smear and HR-HPV tests were performed at the beginning of the study and every 3 months thereafter until a negative result was obtained. Results A total of 121 women with genital HR-HPV infection were enrolled (62 in the study group and 59 in the control group). There was no significant difference in HR-HPV clearance rate between the two groups (58.1% vs. 54.2%). The only factor predicting HR-HPV clearance was a lower initial viral load (HR 3.214; 95% CI: 1.398, 7.392; p = 0.006). Twenty-two women had a mildly abnormal initial cervical smear and nine had an unsatisfactory smear. At 6 months follow-up, both mildly abnormal cervical smear and unsatisfactory smear rates had decreased significantly in the study group compared to the control group ( p = 0.017 and 0.027). Conclusions The application of probiotic strains Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14 did not influence genital HR-HPV clearance, but may have decreased the rates of mildly abnormal and unsatisfactory cervical smears. Trial registration Clinicaltrials.gov NCT01599416 , May, 2012. Retrospectively registered.

“…The application of probiotic strains Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14 concomitantly with specific anti-infective agents provides more reliable cytological diagnostics, reduces the number of false positive and false negative findings on cervical malignancy and normalizes vaginal microflora in higher percentage of patients with vaginal infections compared with therapy including anti-infective agents only [49].…”

Current knowledge point to persistence of risk factors for the development of cervical intraepithelial neoplasia. The infection with a high-risk oncogenic Human Papillomavirus (HPV) subtypes, most commonly 16 and 18, is a necessary, although not sufficient, condition for development of invasive cervical cancer (ICC) and its precancerous precursor, cervical intra-epithelial neoplasia (CIN). It has been suggested that CIN disease severity and the diversity of vaginal microbiota are associated and this may determine viral persistence and disease behaviour. Our work focuses on the genetic variability associated to the modulation of genotoxicity induced by vaginal microbiota diversity. Relatively little is known about the mechanisms associated with clearance or persistence of HPV infection, therefore we hypothesized that may be under the influence of the genetic background.

“…Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14 are two probiotic strains which have shown desirable effects on gynecological diseases [109,110]. Evidence suggests that using Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14 along with antiinfective agents leads to a reduction in false negative and false positive results of cervical malignancies; thus, cytological diagnoses are more reliable with this method [111]. Compared to when using anti-infective drugs alone, applying these probiotic strains provide a higher percentage of vaginal microflora normalization in patients who have vaginal infection [111].…”

Anti-tumor activities of probiotics in cervical cancer

Cervical cancer is considered as an important malignancy among women worldwide. Currently-used treatments of cervical cancer are reported to be cytotoxic for patients. Moreover, these therapies have shown some side effects which can negatively affect the lives of women suffering from this cancer. Therefore, there is need for anti-tumor agents that are less toxic than common therapeutic drugs. Besides, applying agents for preventing or reducing the side effects of cervical cancer therapies can be effective in improving the life quality of cervical cancer patients. Studies have shown that probiotics have several effects on biological processes. One of the most prominent aspects in which probiotics play a role is in the field of cancer. There are multiple studies which have focused on the functions of probiotics in diagnosis, prevention, or treatment of cancer. Besides their direct anti-tumor activities, probiotics can be used as an additional agent for enhancing or modulating other diagnostic and therapeutic methods. Herein, the effects of probiotics on cervical cancer cells are discussed, which may be useful in the prevention and treatment of this cancer. We review the studies concerned with the roles of probiotics in modulating and reducing the gastrointestinal adverse effects caused by cervical cancer therapies. Furthermore, we cover the investigations focusing on the combination of probiotics with other drugs for diagnosis or treatment of cervical cancer.
