Background and Objectives: The relationship between the vaginal microbiota, human papillomavirus infection (HPV), and cervical precancerous lesions is a critical area of research, as it influences both the progression of HPV-related diseases and potential treatment strategies. New evidence suggests that Lactobacillus crispatus dominance in the microbiota may protect against HPV persistence and speed the elimination of HPV. This study aims to explore the relationship between the vaginal microbiota composition and HPV infection, focusing on the impact of these factors on the development of cervical precancerous lesions. Materials and Methods: A comprehensive literature review was conducted using the PubMed database, focusing on studies that analyzed the association between the vaginal microbiota and HPV infection in the context of cervical dysplasia. This study was primarily based on clinical data on HPV integration in women with low-grade squamous intraepithelial lesions (LSILs), high-grade squamous intraepithelial lesions (HSILs), and cervical cancer. Results: Different types of vaginal microbiota communities (CSTs) have different pathogenic or protective potential. Healthy women predominantly exhibited CST I, with Lactobacillus crispatus as the dominant microorganism. CST IV, associated with increased anaerobic bacteria, was most common in HSIL and cervical cancer patients. Statistical analysis revealed that bacterial vaginosis (BV) was significantly associated with HPV persistence, with studies reporting a 1.8–3.4-fold increased risk (p < 0.05) of persistent HR-HPV infection in BV-positive women. Conclusions: Our literature review suggests that the composition of the vaginal microbiota can modulate the local immune response, the expression of viral oncogenes, and the integrity of the epithelial barrier. Furthermore, certain bacterial genes or metabolic pathways can be associated with a favorable or unfavorable outcome of the disease. Analysis of the vaginal microbiota could serve as an additional risk assessment tool, helping to distinguish between regressing and progressive precancerous conditions.

Background and Objectives: Cervical cancer is the fourth most common cancer in women globally. As survival rates gradually increase, it becomes necessary to assess the quality of life (QoL) after treatment. It is known that different treatment modalities have different effects on QoL. Therefore, we aimed to evaluate the QoL of cervical cancer survivors (CCSs) treated with concurrent chemoradiotherapy (CCRT). Materials and Methods: A cross-sectional monocentric study, conducted in Vilnius university hospital Santaros klinikos between November 2018 and November 2022, included 20 women, who were interviewed once using the European Organization for Research and Treatment of Cancer (EORTC)-designed Quality-of-Life questionnaire cervical cancer module (QLQ-CX24). The sociodemographic and clinical data as well as the results of the questionnaire are presented in mean, standard deviation and percentages. The QoL scores were compared between different age and stage groups using the Mann–Whitney U test. Results: Twenty participants, aged from 27 to 55 years, with a mean age of 44 years (SD = 7.6) participated in the study. All the participants were CCSs with an International Federation of Gynecology and Obstetrics (FIGO) stage from IB to IIIB and all of them were treated with CCRT. The symptom experience was relatively low and revealed a good result (21.8, SD = 10.2). Mean scores on body image, sexual/vaginal functioning, menopausal symptoms and sexual worry scales indicated moderate functioning and a moderate level of some of the cervical cancer specific symptoms after CCRT. Sexual activity and sexual enjoyment of the CCSs were low (11.7 (SD = 16.3), 14.3 (SD = 17.8), respectively). Conclusions: Cervical cancer survivors report a relatively good quality of life regarding symptom experience; however, women following concurrent chemoradiotherapy tend not to be sexually active and rarely feel sexual enjoyment. In addition, this treatment modality negatively affects a woman’s body image and self-perception as a woman.

Background. Yolk sac tumour diagnosis should be considered for young age patients admitted to the hospital with non-specific complaints of widespread disease. Correct diagnosis and carefully planned treatment is the key to a successful outcome. Methods and materials. We present a rare case of a widespread yolk sack tumour of a uterine broad ligament. Our team directed a special attention towards the patient’s young age, advanced disease, and fertility sparing strategy of treatment. Results and conclusions. Stage IV yolk sac tumours of extragonadal origin are rarely reported in the literature. Hence, diagnosis and treatment often pose a challenge for emergency care unit doctors, gynaecologists, and oncologists. However, it can be a potentially curable disease. Moreover, patients’ fertility can also be preserved. We believe that further analysis of similar cases is necessary to study outcomes and evaluate patients’ responses to a sequence of medical decisions taken for this specific case.

The role of vaginal dysbiosis in the progression of human papilloma virus (HPV) associated cervical lesions has gained attention in recent years. While many studies use 16S rRNA gene sequencing for microbiota analysis, shotgun metagenomic sequencing offers higher taxonomic resolution and insights into microbial gene functions and pathways. This systematic review evaluates the relationship between compositional and functional changes in the vaginal microbiome during HPV infection and cervical lesion progression. A literature search was performed according to PRISMA guidelines in PubMed, Web of Science, Scopus, and ScienceDirect databases. Seven studies utilizing metagenomic sequencing in patients with HPV infection or HPV-associated cervical lesions were included. Progression from HPV infection to cervical lesions and cancer was associated with a reduction in Lactobacillus species (particularly Lactobacillus crispatus) and an enrichment of anaerobic and pathogenic species, especially Gardnerella vaginalis. Heterogeneous enriched metabolic pathways were also identified, indicating functional shifts during lesion progression. As most studies were conducted in Asia, further research in diverse regions is needed to improve the generalizability of findings. Future studies employing metagenomic sequencing may help identify biomarkers for early pre-cancerous lesions and clarify the role of vaginal microbiota in persistent HPV infection and cervical dysplasia.

Ovarian Leydig cell tumor is a rare type of ovarian steroid cell neoplasms, presenting in only 0.1% of all ovarian tumor cases, and is generally androgen-secreting and unilateral. Although they are often malignant non-spreading tumors, which have excellent prognosis, benign ovarian Leydig cell tumors with low-risk malignancy can be also detected. Ovarian hyperthecosis is a rare non-neoplastic disorder, in most cases bilateral. Ovarian tumors and ovarian hyperthecosis are one of the main causes of hyperandrogenism in postmenopausal women, a condition strongly associated with both hormonal and metabolic changes. Here, we report a 65-year-old patient with complaints of excessive body hairiness and alopecia. The laboratory investigation showed increased levels of serum testosterone and dehydroepiandrosterone sulfate (DHEA-S). Imaging, including transvaginal ultrasound and pelvic MRI revealed the presence of two masses in the ovaries. The patient underwent a laparoscopic bilateral salpingo-oophorectomy due to the ovarian tumors unknown etiology, and histopathological examination revealed a unilateral benign left ovarian Leydig cell tumor with bilateral ovarian stromal hyperplasia and ovarian hyperthecosis. Making differential diagnosis between ovarian tumors and ovarian hyperthecosis is difficult. Bilateral salpingo-oophorectomy is the treatment of choice in postmenopausal women with benign Leydig cell ovarian tumor, as well as ovarian hyperthecosis, as it offers both a cure and diagnostic confirmation.

Germline protein truncating variants (PTVs) in the FANCM gene have been associated with a 2–4-fold increased breast cancer risk in case-control studies conducted in different European populations. However, the distribution and the frequency of FANCM PTVs in Europe have never been investigated. In the present study, we collected the data of 114 European female breast cancer cases with FANCM PTVs ascertained in 20 centers from 13 European countries. We identified 27 different FANCM PTVs. The p.Gln1701* PTV is the most common PTV in Northern Europe with a maximum frequency in Finland and a lower relative frequency in Southern Europe. On the contrary, p.Arg1931* seems to be the most common PTV in Southern Europe. We also showed that p.Arg658*, the third most common PTV, is more frequent in Central Europe, and p.Gln498Thrfs*7 is probably a founder variant from Lithuania. Of the 23 rare or unique FANCM PTVs, 15 have not been previously reported. We provide here the initial spectrum of FANCM PTVs in European breast cancer cases.
