Current oncological developments are based on improved understanding of genetics, and especially the discovery of genes whose alterations affect cell functions with consequences for the whole body. Our work is focused on the one of these genes, BRCA1-associated RING domain protein 1 (BARD1), and its oncogenic role in breast cancer. Most importantly, the study points to new avenues in the treatment and prevention of the most frequent female cancer based on BARD1 research. The BARD1 and BRCA1 (BReast CAncer type 1) proteins have similar structures and functions, and they combine to form the new molecule BARD1-BRCA1 heterodimer. The BARD1-BRCA1 complex is involved in genetic stabilization at the cellular level. It allows to mark abnormal DNA fragments by attaching ubiquitin to them. In addition, it blocks (by ubiquitination of RNA polymerase II) the transcription of damaged DNA. Ubiquitination, as well as stabilizing chromatin, or regulating the number of centrosomes, confirms the protective cooperation of BARD1 and BRCA1 in the stabilization of the genome. The overexpression of the oncogenic isoforms BARD1β and BARD1δ permit cancer development. The introduction of routine tests, for instance, to identify the presence of the BARD1β isoform, would make it possible to detect patients at high risk of developing cancer. On the other hand, introducing BARD1δ isoform blocking therapy, which would reduce estrogen sensitivity, may be a new line of cancer therapy with potential to modulate responses to existing treatments. It is possible that the BARD 1 gene offers new hope for improving breast cancer therapy.

Background: Each year 604,127 new cases of cervical cancer (CC) are diagnosed, and 341,831 individuals die from the disease. It is the fourth most common cancer among women and the fourth most common cause of death from female cancers worldwide. The pathogenesis of CC is associated with human papillomavirus (HPV) infections and consists of several steps involving cell proliferation outside the human body’s control mechanisms. Strategies to prevent CC are based on screening and vaccination. Scope of the Review: The aim of this paper was to collect and analyze the available literature on the issue of CC prevention and the impact of the COVID-19 pandemic on its implementation. For this purpose, PubMed and Google Scholar databases were searched using keywords, such as “cervical cancer”; “HPV”; “prevention”; “prophylaxis”; “vaccination”; “screening” and “COVID-19” in different variations. Only articles published since 2018 were included in the study. Conclusions: Selected European countries have different CC prevention programs funded by national budgets. This translates into observed differences in the risk of death from CC (age-standardized rate Malta = 1.1, Poland = 5.9). COVID-19 pandemic due to disruption of CC screening may exacerbate these differences in the future. To improve the situation, new screening methods, such as p16/Ki67, HPV self-testing, and the use of artificial intelligence in colposcopic assessment, should be disseminated, as well as free HPV vaccination programs implemented in all countries. The search for new solutions is not without significance and entails ultra-sensitive screening tests for risk groups (mRNA E6/E7, SOX1/SOX14), HPV vaccines with shorter dosing schedules, and new therapeutic pathways using nanotheranostics.

Background and Objectives: Cervical cancer (CC) is the fourth most common cause of cancer-related morbidity and mortality among women worldwide. CC prevention is based on screening and HPV vaccination. The COVID-19 pandemic has caused difficulties in implementing CC-preventative measures. The aim of this study was to collect data on the implementation of CC prophylaxis in Poland provided by public and private health care with a particular focus on the impact of the COVID-19 pandemic and attempt to estimate the level of CC-screening implementation by 2026 under public and private health care. Materials and Methods: Data on the implementation of privately funded (2016–2021) and publicly funded (2014–2021) CC-preventative measures in Poland were examined. The Prophet algorithm, which positions itself as an automatic forecasting procedure and represents a local Bayesian structural time-series model, was used to predict data. The correlation test statistic was based on Pearson’s product moment correlation coefficient and follows a t distribution. An asymptotic confidence interval was given based on Fisher’s Z transform. Results: In 2021, a significantly higher population screening coverage was observed in private health care (71.91%) than in the public system (12.6%). Our estimation assumes that the adverse downward trend of population coverage (pap smear CC screening) in the public system will continue to 5.02% and in the private health system to 67.92% in 2026. Correlation analysis showed that with the increase in the sum of HPV tests and LBC, the percentage of Pap smear coverage in the private healthcare sector decreases r = −0.62, p = 0.260 df = 3, CI = [−0.97, 0.57]. The amount of HPV vaccinations provided in private health care is steadily increasing. Immunization coverage of the population of girls aged 9–18 years under private health care at the end of the observation period was 4.3% (2021). Conclusions: It is necessary to reorganize the public CC-screening system in Poland based on a uniform reporting system for tests performed in both public and private health care using the model of action proposed by us. We recommend the introduction of a national free HPV vaccination program funded by the government and implemented in public and private health care facilities.

Cervical uterine cancer is the second most frequent female cancer worldwide and a substantial burden for low-income societies and the patients themselves. Understanding the molecular mechanisms of metastasis permits the development of therapies that limit tumor progression, as well as providing health and social benefits. Pathomorphology is still the basis of research and a reference standard for molecular analysis. The aim of our study was to research and critically evaluate clinical trials that use new oncological approaches for node-positive cervical cancer to gain an insight into the molecular mechanisms of tumor metastasis. Inclusion criteria: node-positive disease at baseline; at least a first phase clinical study comprising adult female patients; novel clinical approach (e.g., radiotherapy, immunotherapy, targeted therapy, vaccines, radiosurgery); histologic measurement of treatment efficacy (preferably lymph node ultrastaging); and publications in English language only. Information sources: US Clinical trials registry, EU Clinical trials register, ISRCTN registry, and Ovid, EBSCO and Cochrane Collaboration databases. Access dates: from January 2010 to April 2018. Exclusions: Abstracts that did not meet the inclusion criteria or with unreliable data. We collected complete data (e.g., the entire publication associated with included abstracts, heterogeneity examination of individual studies, and validity measurement of the statistical methods used). Results were analyzed in relation to the most recent understanding of the pathogenesis of cervical cancer metastasis. We proposed a possible direction for drug treatment of epithelial tumors based on the mechanisms of metastasis.

Proper targeted cancer prophylaxis reduces the incidence of cancer in all forms; this includes cancers with significant progression potential and poor prognosis. Based on the assumption that one of the risk factors of cervical cancer is the avoidance of screening tests, we analyzed the current scenario of cervical cancer (CC) screening and recommendations in Poland (country with a well-off socioeconomic status). Based on the comprehensive literature review concerning documents of guidelines and recommendations of various bodies, including national ones, data on the implementation of CC screening in Poland, and different models for medium-to-high-income countries, we proposed how the CC screening strategy could be improved. Finally, the new strategy was further developed for those who are prone to not being screened. The proposal on how to improve the Polish CC screening program is the following: refinement of the public education on CC risk factors, popularization of CC screening incentives amongst the public, and improvement of networking strategies between CC screening facilities (“cervical screening clinical”), allowing screenings to be more efficient and rapid. We believe that, to enhance the future quality of life of those with rapid CC progression by catching the disease preemptively and limiting the sequelae of the disease, we have to improve education and access to medical services.

Background/Objectives: Cervical cancer is the second most common gynecological cancer worldwide, preventable through screening initiatives and vaccinations against its causative agent, anogenital human papillomavirus (HPV). This study aimed at measuring the coverage and uptake of the national HPV vaccination program launched in 2023 and implemented throughout Poland. Methods: This cross-sectional, observational study analyzed population data of adolescents in 11–13-year-old groups vaccinated in individual voivodeships (provinces) of Poland as provided by the National Health Fund and the Central Statistical Office. A p-value of <0.05 was considered statistically significant. Results: The rate of HPV vaccination participation under the population program was 8.67%. In the analyzed age groups, in both sexes, no statistically significant correlation was observed between the population size at a given age and population coverage or participation in HPV vaccination. However, a positive relationship in vaccination coverage was observed in individuals previously vaccinated with one dose in subsequent age groups, indicating a continued willingness to receive vaccination with further doses. No statistically significant difference in population coverage changes across voivodeships was found between the number of doses within the urban population share vs. rural population share. Conclusions: Our results show that, at 1.5 years of implementation of the national HPV vaccination program, the coverage and uptake of the program is considerably insufficient. The intensive corrective actions indicated are required to pave this program forward towards optimum results.
