Objective To explore the expression levels of CD33⁺ myeloid-derived suppressor cell (MDSC)-mediated T lymphocyte function and related inflammatory factors secreted by T lymphocyte subsets in patients with cervical cancer, and to analyze their correlation with the treatment efficacy of ¹²⁵I particle implantation combined with arterial chemoembolization, as well as predictive value for treatment outcomes and interaction effects. Methods From January 1st, 2021 to January 1st, 2024, our hospital admitted 152 patients with advanced cervical cancer, who were confirmed by pathological examination. All patients received uterine artery chemoembolization combined with ¹²⁵I particle implantation. The predictive value of CD33⁺MDSC levels for clinical treatment response in cervical cancer was assessed using receiver operating characteristic (ROC) curve analysis. Multivariate logistic regression analysis was performed to evaluate both multiplicative and additive interactions between CD33⁺MDSC and T lymphocytes in predicting clinical treatment failure of cervical cancer. Kaplan Meier method was used to analyze the survival differences between cervical cancer patients with high and low CD33⁺MDSC expression levels. Results Compared with the effective group, patients in the ineffective group had decreased expression levels of CD3⁺ T lymphocyte, CD4⁺ T lymphocyte, interleukin 2 (IL-2) and interferon γ (IFN-γ), while showing increased expression levels of CD33⁺MDSC, CD8⁺ T lymphocyte, IL-4 and IL-6, along with increased tumor necrosis factor α (TNF-α) levels, larger maximum tumor diameters, and a higher incidence of lymph node metastasis. The expression levels of CD33⁺MDSCs demonstrated good predictive performance for treatment efficacy in cervical cancer patients. The high CD33⁺MDSC expression group had a significantly shorter overall survival (OS) than the low CD33⁺MDSC expression group (6.0±1.0 months vs. 12.0±1.2 months; t=33.280). The interaction analysis revealed that CD33⁺MDSCs and CD8⁺ T lymphocytes were highly expressed, while CD3⁺ and CD4⁺ T lymphocytes were lowly expressed, which was associated with an increased risk of clinical treatment failure in cervical cancer patients. Conclusion CD33⁺MDSCs can inhibit CD3⁺ and CD4⁺ T lymphocytes. It can upregulate the expression of CD8⁺ T lymphocytes, form an immunosuppressive microenvironment, and reduce the treatment response rate of ¹²⁵I particle implantation combined with arterial chemoembolization. CD33⁺MDSCs may serve as an independent biomarker for predicting the therapeutic efficacy and poor prognosis.

BACKGROUND

Cervical cancer, caused by human papillomavirus (HPV), is the second most common cancer among Filipino women. Despite vaccine availability, the Philippines has a low 60% immunization rate, driven by hesitancy and poor public awareness.

AIMS AND OBJECTIVES

This study assessed how 100 women (ages 18–45) in Quezon City understood HPV and their willingness to vaccinate.

MATERIALS AND METHODS

Researchers used a pre–post interventional study and purposive sampling and Cochran’s formula for size calculation. Participants completed a pretest, a Department of Health/World Health Organization/Centers for Disease Control and Prevention-based digital educational intervention, a posttest, and a satisfaction survey. Data were gathered confidentially under informed consent.

RESULTS

Results showed significant improvement in knowledge and willingness to vaccinate (P < 0.001), with almost all respondents expressing willingness. The intervention received high satisfaction ratings, proving the digital tool was effective and well-received.

CONCLUSION AND RECOMMENDATION

In conclusion, this study demonstrated that a structured digital educational tool effectively bridges knowledge gaps and addresses vaccine hesitancy in a community setting. Findings emphasize the importance of targeted, community-level initiatives to reduce cervical cancer risk. Future research should include teens and males and use a larger randomized sample for definitive evidence.

BACKGROUND OF THE STUDY

The treatment for cervical cancer among young women can result in adverse effects that contribute to a negative quality of life (QOL). The literature shows varied studies on the QOL of cervical cancer patients, but evidence on the local context is limited, particularly in young patients.

OBJECTIVES

This study aimed to determine the QOL of young women with cervical cancer treated with concurrent chemoradiation.

MATERIALS AND METHODS

A prospective cross-sectional research design was employed. A total of 72 cervical cancer patients who were 40 years old and younger and treated with chemoradiation were recruited using complete enumeration. The study locale was in a tertiary government hospital, which is a training center for gynecologic oncology in the Philippines. The European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-C30 and EORTC QLQ of women with Cervical Cancer (CX24) served as data collection instruments. Descriptive statistics were utilized to describe and synthesize the data.

RESULTS

Seventy-two young women with cervical cancer treated with concurrent chemoradiation reported a mean global health status score of 4.75, indicating a moderate QOL. However, functional domains were generally low, with the lowest scores in cognitive (1.71), social (1.64), and physical interference with social activities (1.96). The average symptom score was 2.10, reflecting moderate symptomatology. On the EORTC QLQ-CX24, most QOL aspects were rated low, except for body image (2.01), menopausal symptoms (2.31), and sexual worry (2.79). Sexual enjoyment scored the lowest at 1.16, with an overall average of 1.71.

CONCLUSIONS

The study highlights low-to-moderate QoL among young cervical cancer patients post-chemoradiation, underscoring the need for improved supportive care addressing physical, psychological, and social challenges caused by the disease and treatment modality.

Although commonly seen in the ovary, fallopian tube, peritoneum, and endometrium, the serous carcinoma histology is considered a rare subtype when seen in the cervix. The prevalence of cervical adenocarcinoma, including serous carcinoma, varies between 5% and 15% of all cervical malignancies. A thorough literature study revealed only 113 cases of serous carcinoma of the cervix, highlighting its infrequency relative to other cervical cancer variants. As a subtype of adenocarcinoma, serous carcinoma of the cervix has aggressive characteristics and usually unfavorable prognosis, more so its clinicopathological characteristics are relatively unclear because of its rarity and limited number of cases and reviews seen in literature. This is a case of a 44-year-old G3P3 with a primary complaint of heavy vaginal bleeding. The diagnosis of serous carcinoma of the cervix was made by histopathological evaluation, confirmed by immunostaining. With physical examination and diagnostic imaging confirming an early stage disease, the patient successfully underwent primary surgical management.

Embryonal rhabdomyosarcoma of the uterus is a rare condition with only a few cases documented. Exceedingly rare, however, is its concomitant incidence with uterine inversion. The infrequency with which genital tract sarcoma with uterine inversion is encountered makes the diagnosis and management a formidable challenge. The present case reports a 12-year-old nulligravida who complained of a rapidly growing introital mass of 3-month duration. Suspicion of nonpuerperal uterine inversion was confirmed by imaging, and malignancy was proven through adequate tissue sampling. While there is no unified protocol in the management of prolapsed genital tract sarcomas, the complete inversion of the corpus necessitated surgery. In the case presented, exploratory laparotomy and total hysterectomy through a double setup, abdomino-vaginal approach was done. The case illustrates the diagnostic, therapeutic, and ethical dilemmas in handling an aggressive tumor in an adolescent. Early recognition and a multidisciplinary approach are extremely crucial in ensuring improved prognosis and holistic treatment.

OBJECTIVES: To analyze the global disease burden of cervical cancer and the association between screening coverage and the quality of disease management. METHODS: The data of global burden of cervical cancer 2021 and the data of cervical cancer screening 2019 were obtained from IHME Global Burden of Disease (GBD) and the WHO global health observatory, respectively. The age-standardized disease burden index was calculated, the quality of care index (QCI) was determined with principal component analysis, and the correlation between QCI and cervical cancer screening coverage was examined with linear regression analysis by regions and populations. RESULTS: The burden of cervical cancer and the quality of management exhibited significant variability across countries with differing levels of social development. The indicators of cervical cancer burden in China were close to the average level of countries with higher socio-demographic index (SDI). The global QCI was 22.22 (10.50, 35.43), and that of China was 26.30. The global screening coverage rate for cervical cancer was 42% (12%, 86%) and that in China was 31%. After adjusting for the social development level of countries, the coverage level of cervical cancer screening was associated with QCI (β=0.27, P<0.01), with no difference between low and high SDI countries (P>0.05). The association was significantly stronger among 25-30 years old women (β=1.48, P<0.05). CONCLUSIONS There are discrepancies in both the disease burden of cervical cancer and the quality of disease management among countries with different socioeconomic levels, and there is still considerable room for improvement in China. Expanding coverage of cervical cancer screening may be an effective strategy to enhance the management quality of cervical cancer, particularly among younger women where the screening benefits are most pronounced.

BACKGROUND

Cervical cancer remains to be the second leading cancer and cause of cancer-related deaths among Filipino women despite the use of the Papanicolaou screening. Latest research has shown that the human papillomavirus (HPV) is a necessary cause of cervical cancer. With major morbidity and high mortality rates associated with HPV infection and cervical cancer, several modes of primary and secondary forms of prevention have to be implemented. Among the primary modes of prevention is the administration of the preventive vaccine, which has consistently shown to decrease substantially HPV disease and cervical cancer rates in developed countries. In our country, before a successful vaccination, program is implemented, several sociocultural issues have to be addressed. Knowledge, attitude, and motivational factors are vital in determining acceptance of the vaccine. One relevant setting is exploring the willingness of mothers to get their female children vaccinated even before they become sexually active.

OBJECTIVES

The aim of the study was to determine the association of the knowledge, attitude, and motivational factors of mothers on their willingness for their female children aged 9–13 years to undergo HPV vaccination at a tertiary government hospital.

STUDY DESIGN

This was a cross-sectional study that was carried out at a government institution.

POPULATION

The population consisted of 352 mothers with female children aged 9–13 years consulting the outpatient clinics at the department of obstetrics and gynecology at a tertiary government hospital.

MATERIALS AND METHODS

A pretested and validated survey was given to 352 respondents. They were asked to answer a self-administered questionnaire that included sociodemographic, reproductive, sexual history variables, knowledge, and attitude, and motivational factors toward the disease and the associated vaccine.

RESULTS

Using the survey proportion estimation methods, the prevalence of women who were willing to enroll their daughters for HPV vaccination was 97.18% (n = 42, 95% confidence interval [CI]: 94.91 to 98.46%). It can be noted that only a third of the sample had high knowledge on the vaccine and its use 34.93% (n = 124, 95% CI: 30.25 to 39.92%). More women who reached college level (χ2: 5.67) and also those whose youngest child was between 11 and 13 years old (χ2: 8.82)-had higher knowledge scores than otherwise. Those who have an annual income of greater than or equal to P 60,000 (χ2: 16.55) and are non-Catholic (χ2: 18.77) – also appeared to have higher knowledge ratings on the questionnaire. Women who never to a few times a year attend church-related activities had higher knowledge scores compared to women who were more frequent goers (χ2: 16.33). For the attitude toward the vaccine, more mothers believed that getting the vaccine would not have an effect on a girl’s sexual activity and most agreed that they would not be viewed as bad parents. Most women also did not believe that religion would affect their willingness to vaccinate their children. There was an association in the degree of agreement between negative and positive attitudes from the Chi-square test performed (χ2: 7.44, P: 0.01). There were more agreeing responses from factors determining positive attitude and more disagreeing responses in the factors determining negative attitude. With regard to motivational factors, more women agreed that the cost was prohibitive and that they were more willing if only two doses would be required for their daughters. They were also not concerned about what other parents may think about getting the vaccine. Most answered that they were willing to follow their doctors’ recommendations and they have trust in vaccine manufacturers. Most women were also concerned that their daughters may get cervical cancer in the future. There was no difference in the proportion of agreeing responses between positive and negative motivating factors among the study participants (Z: 0.30, P: 0.79). This suggested that these factors could be important predictors of willingness to use vaccination on their children. Based on the crude odds ratios from the logistic regression, the likelihood of being willing to administer HPV vaccine to their children was almost twice as the knowledge score and scores on the positive attitude items increased, and was found to be statistically significant. At the same time, the odds of willingness increased by more than twice as the score on the negative attitude items decreased, and was also significant. There was no noted association for the other predictors of the association.

CONCLUSION

The role of knowledge and attitudes on the negative perceptions on the vaccine were important predictors of the willingness of mothers to have their female children vaccinated against HPV infection.

In Mayer-Rokitansky-K0ster-Hauser (MRKH) syndrome, the development of the uterus and some parts of the vagina is either completely absent or reduced. It is a rare congenital anomaly, and affects one in 4,000-5,000 female births and commonly presents as primary amenorrhea. Approximately 6% - 10% of these patients with MRKH syndrome report persistent pelvic pain, which may be attributed to the presence of myomas, endometriosis, adenomyosis or hematometra caused by a functioning endometrial tissue in a uterine remnant. This paper presents the case of a 37 year old nulligravid who experienced severe cyclic hypogastric pain, and was subsequently diagnosed with MRKH syndrome with adenomyosis. Clinical evaluation and definitive management of the index case are discussed.

There have been recent, significant changes in strategies and policies for elimination of cervical cancer and advances in research of human papillomavirus (HPV)-related diseases and their prevention and control. Based on the latest national and international research, and building on a consensus published in 2019, we developed an expert consensus on immunoprophylaxis of cervical cancer and other human papillomavirus-related diseases (2025 edition) in order to provide clinicians, disease prevention and control professionals, and vaccination staff a reference for the prevention and control of cervical cancer and other HPV-related diseases and systematic, comprehensive evidence-based support for the scientific use of HPV vaccines to optimize their prevention effectiveness.

BACKGROUND: Cervical squamous cell carcinoma (CESC), the most common subtype of cervical cancer, is primarily caused by the high-risk human papillomavirus (HPV) infection and genetic susceptibility. Single-cell RNA sequencing (scRNA-seq) has been widely used in CESC research to uncover the diversity of cell types and states within tumor tissues, enabling a detailed study of the tumor microenvironment (TME). This technology allows precise mapping of HPV infection in cervical tissues, providing valuable insights into the initiation and progression of HPV-mediated malignant transformation. METHODS: We performed the scRNA-seq to characterize gene expression in tumor tissues and paired adjacent para-cancerous tissues from four patients with early-stage CESC using the 10× Genomics platform. The HPV infection and its subtypes were identified using the scRNA data and viral sequence mapping, and trajectory analyses were performed using HPV+ or HPV- cells. Interactions between different types of keratinized cells and their interactions with other cell types were identified, and pathways and specificity markers were screened for proliferating keratinized cells. The Cancer Genome Atlas (TCGA) dataset was used to verify the prognostic correlation between tumor-specific PI3+S100A7+ keratinocyte infiltration and CESC, and the localization relationship between PI3+S100A7+ keratinocytes and macrophages was verified by immunofluorescence staining. RESULTS: Various types of keratinocytes and fibroblasts were the two cell types with the most significant differences in percentage between the tumor tissue samples and paired adjacent non-cancerous tissue samples in the early stages of CESC. We found that PI3+S100A7+ keratinocytes were associated with early HPV-positive CESC, and PI3+S100A7+ keratinocytes were more abundant in tumors than in adjacent normal tissues in the TCGA-CESC dataset. Analysis of clinical information revealed that the infiltration of PI3+S100A7+ keratinocytes was notably higher in tumors with poor prognosis than in those with good prognosis. Additionally, multiplex immunofluorescence analysis showed a specific increase in PI3+S100A7+ expression within tumor tissues, with PI3+S100A7+ keratinocytes and CD163+ macrophages being spatially very close to each other. In the analysis of cell-cell interactions, macrophages exhibited strong crosstalk with PI3+S100A7+ proliferating keratinocytes in HPV-positive CESC tumors, mediated by tumor necrosis factor (TNF), CCL2, CXCL8, and IL10, highlighting the dynamic and tumor-specific enhancement of macrophage-keratinocyte interactions, which are associated with poor prognosis and immune modulation. Using CIBERSORTx, we discovered that patients with high infiltration of both PI3+S100A7+ proliferating keratinocytes and macrophages had the shortest overall survival. In the analysis of cell-cell interactions, PI3+S100A7+ proliferating keratinocytes and macrophages were found to be involved in highly active pathways that promote differentiation and structure formation, including cytokine receptor interactions, the Nuclear Factor kappa-light-chain-enhancer of activated B cells (NF-κB) signaling pathway, and TNF signaling pathway regulation. Further subtyping of fibroblast populations identified four subtypes. The C1 group, characterized by its predominance in tumor tissues, is a subtype enriched with cancer-associated fibroblasts (CAFs), whereas the C3 group is primarily enriched in adjacent non-cancerous tissues and consists of undifferentiated cells. Moreover, the distinct molecular and cellular differences between HPV16- and HPV66-associated tumors were demonstrated, emphasizing the unique tumor-promoting mechanisms and microenvironmental influences driven by each HPV subtype. CONCLUSIONS We discovered a heterogeneous population of keratinocytes between tumor and adjacent non-cancerous tissues caused by HPV infection and identified macrophages and specific CAFs that play a crucial role during the early stage in promoting the inflammatory response and remodeling the cancer-promoting TME. Our findings provide new insights into the transcriptional landscape of early-stage CESC to understand the mechanism of HPV-mediated malignant transformation in cervical cancer.
