RESUMO
Research suggests that encounters with racism are related to depression in Black youth. However, less is known about how experienced racial discrimination can influence other aspects of well-being among Black youth including their socio-emotional development and behavior. In addition, emerging literature highlights the critical ways anticipated racial discrimination may impact the emotional well-being of Black youth. To address these gaps, the current study assessed whether experienced discrimination was associated with higher levels of internalizing problems (anxiety/depression, suicidal thoughts) and lower levels of socio-emotional development (emotion regulation, prosocial behavior). We then tested whether expected discrimination contributed to similar patterns. Lastly, this study examined how age and gender moderated this relationship. Across eight schools in three communities, 1435 Black youth (56.57% female; 56.40% 10th grade) in 10th and 12th grades responded to the Youth Experience Survey. Using a series of hierarchical linear and hierarchical binary logistic regressions, results found that those who experienced racial discrimination and expected discrimination demonstrated higher internalizing problems and lower socio-emotional development; however, expected discrimination often accounted for more variance than experienced. These findings suggest the multifaceted influence both experienced and expected racial discrimination have on the well-being of Black youth and can provide important insights to community prevention systems.

BACKGROUND: Gonadotropin-releasing hormone agonists are used to treat premenopausal uterine leiomyomas; however, leiomyoma volume reduction is not always achieved. The reduction rate after this treatment varies for each leiomyoma, even in the same patient. Therefore, an effective method for predicting uterine leiomyoma volume reduction is required to reduce the adverse hypoestrogenic effects and drug-related economic burden related to gonadotropin-releasing hormone agonists. OBJECTIVE: This study aimed to determine the predictive use of MED12 mutations for evaluating the effect of gonadotropin-releasing hormone agonist treatment concerning reducing uterine leiomyoma volume and to predict the MED12 mutation status based on the findings of magnetic resonance imaging performed before treatment. STUDY DESIGN: MED12 exon 2 mutation and erythropoietin expression in uterine leiomyomas were evaluated concerning volume reduction, as measured using magnetic resonance imaging. We developed a system for classifying leiomyomas according to T2-weighted magnetic resonance imaging signals to noninvasively predict the presence or absence of MED12 mutations in leiomyomas. Leiomyoma samples (>5 cm) were obtained from 168 patients during surgery (hysterectomy or myomectomy) between 2005 and 2021 at Yokohama City University Hospital. To analyze the rate of leiomyoma volume reduction, 41 patients had been preoperatively administered the gonadotropin-releasing hormone agonist (leuprorelin acetate 3.75 mg, monthly subcutaneous injection) for 3 months; magnetic resonance imaging was performed before and after treatment without contrast material. RESULTS: Patients with MED12 exon 2 mutations had smaller volume reduction after treatment with the gonadotropin-releasing hormone agonist (P<.001, Mann-Whitney U test) and displayed lower signal intensity on T2-weighted images than those with leiomyomas expressing wild-type MED12 exon 2. The newly proposed magnetic resonance imaging-based classification system showed that MED12 exon 2 mutations were more frequent in the low-signal group than in the high-signal group, with nearly equal proportions of mutated and wild-type MED12 exon 2 leiomyomas noted in the intermediate group. The low-signal group had significantly lower erythropoietin expression levels than the high-signal group (P<.001, Kruskal-Wallis test with the Dunn posthoc analysis). CONCLUSION: MED12 mutation status can be a candidate marker for predicting the effect of gonadotropin-releasing hormone agonists on uterine leiomyoma reduction. Magnetic resonance imaging findings can be used to determine MED12 mutation status as a noninvasive strategy to select patients who will most likely benefit from gonadotropin-releasing hormone agonist treatment.

BACKGROUND: The purpose of this study was to develop a cervical cancer education program for students and evaluate the process for female students of an HPE teacher education university who were training to become Japanese Health and Physical Education teachers. METHODS: This study used Action Research (AR) methodology. In developing program, we analyzed the description of the teaching material development process, the lectures, and the students' report contents, which was the main activity in the program development. Thirty five third- and fourth-year students majoring in health promotion at a Health and Physical Education teacher education university, which trains Health and Physical Education teachers in Tokyo, Japan, participated in this study. RESULTS: After a review of the prototype version of the cervical cancer education material, six out of nine reviewers determined that it can be published. In the revised cervical cancer education materials, messages from students, university lecturers, and gynecologists have been added as a column in the section on 'how to prevent cervical cancer. Analysis of the contents of the texts (16,792 characters in total) of 35 student reports resulted in the generation of 51 codes, 3 categories, and 15 subcategories. CONCLUSIONS: This study reflects the intentions of female university students to contribute their knowledge to the development of educational materials on cervical cancer, which, alongside the lectures, have deepened the knowledge and awareness of cervical cancer. Based on this, the teaching material development process, lectures by experts, and students' mindset after learning about cervical cancer is reported in this study. There is a need for more educational programs on cervical cancer that are implemented through the education of female university students.

AIM: To evaluate changes of treatment strength and its impact on prognosis in older patients with ovarian cancer. METHODS: We compared relative dose intensity (RDI) as a representative of treatment strength, prognosis, and other features between older (≥65 years) and younger patients (<65 years) retrospectively. Seventy-seven older patients of 301 who received dose-dense-paclitaxel-carboplatin (dTC) and 93 older patients of 304 who received conventional-paclitaxel-carboplatin (cTC) from the Japanese Gynecologic Oncology Group (JGOG) 3016 clinical trial were analyzed. RESULTS: The RDI of older patients was lower than that of younger patients in cTC (87.4% vs. 90.8%, p = 0.009) but not in dTC (79.0% vs. 81.2%, p = 0.205). In both regimens, older patients had worse overall survival than younger patients: hazard ratio [HR] = 1.80; 95% confidence interval [CI]: 1.25-2.59; p = 0.001 for dTC, and HR = 1.59; 95% CI: 1.15-2.19; p = 0.04 for cTC. However, the RDI was not determined as a prognostic factor statistically. The prognostic factors identified by multivariate analysis for both regimens were clinical stage and residual disease; for dTC were age, performance status, and serum albumin; and for cTC was white blood cell count. There was no difference in neutropenia observed between age groups in either regimen. CONCLUSIONS: The RDI of older patients varies according to the administered schedule and is not always lower than that of younger patients. Older patients with comparable treatment strength to younger patients in the dTC group did not accomplish the same level of prognosis as younger patients. Other biologic factors attributable to aging may affect prognosis.

Formation of primordial follicles is a fundamental, early process in mammalian oogenesis. However, little is known about the underlying mechanisms. We herein report that the RNA-binding proteins ELAVL2 and DDX6 are indispensable for the formation of quiescent primordial follicles in mouse ovaries. We show that Elavl2 knockout females are infertile due to defective primordial follicle formation. ELAVL2 associates with mRNAs encoding components of P-bodies (cytoplasmic RNP granules involved in the decay and storage of RNA) and directs the assembly of P-body-like granules by promoting the translation of DDX6 in oocytes prior to the formation of primordial follicles. Deletion of Ddx6 disturbs the assembly of P-body-like granules and severely impairs the formation of primordial follicles, indicating the potential importance of P-body-like granules in the formation of primordial follicles. Furthermore, Ddx6-deficient oocytes are abnormally enlarged due to misregulated PI3K-AKT signaling. Our data reveal that an ELAVL2-directed post-transcriptional network is essential for the formation of quiescent primordial follicles.

AIM: Although the procedure of abdominal trachelectomy has been remarkably improved, preventing subsequent cervical stenosis remains challenging. In this study, we analyzed the clinicopathological risk factors for cervical stenosis to explore the appropriate surgical procedures for the prevention of cervical stenosis following trachelectomy. METHODS: Thirty-two patients who underwent abdominal extended and radical trachelectomy were assessed retrospectively (median follow-up period = 33 months). To evaluate the risk factors, the clinicopathological factors were analyzed by univariate and multivariate analyses. The reconstructed uterine length (UtL), that is, the length between the vaginal end of the neo-cervix and the uterine fundus, was measured by transvaginal ultrasound after surgery. The cut-off value for the UtL was assessed by a receiver operating characteristic (ROC) curve analysis. RESULTS: Cervical stenosis of any grade was observed in 12 patients (grade 1 = 9, grade 3b = 3). Among the various clinicopathological factors, the UtL and cervical length (CL) were significantly related to cervical stenosis following trachelectomy. The multivariate analysis revealed that the UtL, but not CL, is an independent risk factor for stenosis. The ROC curve analysis revealed that stenosis was significantly more likely to occur in patients with a UtL shorter than 53 mm (area under the ROC curve = 0.902). UtL in the patients who became pregnant was longer than that in the patients who did not. No evidence of recurrent cancer was observed during the follow-up period. CONCLUSION: Our proposed method may provide a functional reconstructed uterus with preserving fertility by remaining UtL more than 53 mm.

We previously reported that aberrant expression of atypical protein kinase C λ/ι (aPKCλ/ι) in low-grade squamous intraepithelial uterine cervix lesions was associated with an increased risk of progression to higher grade. This study aimed to investigate aPKCλ/ι expression patterns in cervical squamous cell carcinoma (SCC) and its association with disease progression. We immunohistochemically assessed aPKCλ/ι expression in 168 SCC samples and 13 normal uterine cervix samples. In 69.0% of SCC cases, aPKCλ/ι was expressed more abundantly than in normal epithelium, but there was no significant association between aPKCλ/ι intensity and disease progression (P=0.087, Cochran-Mantel-Haenszel test). aPKCλ/ι in normal cervical epithelium was confined to the cytoplasm or intercellular junctions. In contrast, aPKCλ/ι was predominantly localized within the nucleus in 36.9% of SCC samples (P<0.001, χ test), and the prevalence was significantly increased relative to advanced tumor stage (P<0.001, Cochran-Mantel-Haenszel test). Moreover, patients with SCC with aPKCλ/ι nuclear localization had worse prognoses than those with cytoplasmic localization (P<0.001, log-rank test). aPKCλ/ι localization differed between the intraepithelial lesion and adjacent invasive cancer in 40% of cases, while the expression pattern was similar between primary and matched metastatic tumors. In conclusion, aPKCλ/ι nuclear localization in cervical cancer is associated with tumor progression and worse prognosis. This is the first report to show aberrant nuclear aPKCλ/ι localization in a subgroup of cervical cancer patients and its association with worse prognosis.

We developed an HPV16 E7-expressing Lactobacillus-based therapeutic vaccine, IGMKK16E7, to elicit mucosal E7-specific TH1 cellular immune responses. This study aims to examine the safety and clinical efficacy of IGMKK16E7 on HPV16-positive high-grade squamous intraepithelial lesion (HSIL). This is a multicenter, placebo-controlled, double-blind randomized phase I/II trial to test the safety and efficacy of IGMKK16E7 against HPV16-positive HSIL. The groups will include placebo, low-dose (0.5 g/day), middle-dose (1 g/day), and high-dose (1.5 g/day) IGMKK16E7. The target sample size will be 41 patients per group, and our data on our former agent, GLBL101c, were used to calculate sample size for 70% power and an α level = 0.05. The primary endpoint is IGMKK16E7 safety and pathological regression at week 16, and the secondary endpoints are cytological regression and HPV16 E7 immunological response. This study protocol has been approved by the Japanese Pharmaceuticals and Medical Devices Agency. Patient enrollment will begin in May 2019.

BACKGROUND: We encountered a woman with vaginal cancer that was associated with complete uterine prolapse and complicated by severe intrauterine adhesions. In this case report, we describe the clinical course and successful treatment of this rare condition. CASE PRESENTATION: A 78-year-old woman (gravida 10, para 2, abortion 8) with a 10-year history of uterine prolapse presented for evaluation of bleeding from an ulceration on the surface of the irreducibly prolapsed uterus. Biopsy of a mass on her vaginal wall led to a diagnosis of keratinizing squamous cell carcinoma. Her history of eight abortion procedures had resulted in severe intrauterine adhesions, preventing tandem insertion and intracavitary brachytherapy. She was also ineligible for surgery under general anesthesia + chemotherapy because of her advanced age and presence of arrhythmia. Therefore, we devised an extensive treatment plan involving high-dose-rate interstitial brachytherapy. This treatment successfully eliminated the squamous cell carcinoma as confirmed by biopsy with no recurrence or severe late complications. CONCLUSIONS: We found that high-dose-rate interstitial brachytherapy may be a very effective therapeutic strategy for this condition with few adverse effects.

BACKGROUND: This was the first large-scale prospective observational Japanese study evaluating the safety and efficacy of bevacizumab combined with paclitaxel and carboplatin for newly diagnosed advanced ovarian cancer. METHODS: Patients were prospectively enrolled in the primary analysis cohort if they had Stage III or IV epithelial ovarian/fallopian tube/primary peritoneal cancer and were scheduled to receive paclitaxel plus carboplatin every 3 weeks in Cycles 1-6 and bevacizumab every 3 weeks in Cycles 2-22. Primary endpoints were bevacizumab-specific adverse events and adverse events ≥ Grade 3. Secondary endpoints were progression-free survival (PFS) and the response rate. RESULTS: Among 346 patients enrolled, 293 patients formed the primary analysis cohort. Regarding bevacizumab-specific adverse events ≥ grade 3, incidence rates of thromboembolic events (1.4%), gastrointestinal perforation (0.3%), fistula (0.7%), wound dehiscence (0%), and bleeding (0%) were very low. While incidence rates of hypertension (23.2%) and proteinuria (12.6%) were high, all such events were tolerable. No patient with prior bowel resection developed perforation or fistula. Median PFS was 16.3 months (95% CI 14.5-18.9). The response rate was 77.5% (95% CI 67.4-85.7). The response rate was 63.6% in patients with clear cell carcinoma, which tended to be better than previously reported. The median platinum-free interval was 11.5 months, and the platinum-resistant recurrence rate was 24.5%. CONCLUSIONS: Combining bevacizumab with chemotherapy was tolerable and efficacy was acceptable in Japanese patients with advanced epithelial ovarian cancer. Bevacizumab seems to reduce platinum-resistant recurrence and is promising for clear cell carcinoma.

OBJECTIVE: To examine the necessity and sufficiency of different types of hysterectomy for the surgical treatment of endometrial cancer. METHODS: This was a multicenter collaborative study conducted by 11 institutions. Among patients with stage I-III endometrial cancer who underwent surgery as the initial treatment (only chemotherapy was provided if adjuvant therapy was needed) from 2001 to 2012, we retrospectively examined the type of hysterectomy, clinicopathological factors, recurrence rate over a maximum period of 5 years, and the site of recurrence. The local recurrence rate was examined by univariate and multivariate analyses. RESULTS: Among 1335 patients, 982 (73.6%) underwent simple hysterectomy (SH) and 353 (26.4%) underwent modified radical hysterectomy (mRH) and were observed for a mean duration of 51.8 months. No significant difference was observed in the rate of local recurrence between the SH and mRH groups (p = 0.928). In multivariate analysis, clinicopathological factors independently associated with localized recurrence included postmenopausal status [hazard ratio (HR) 5.036, 95% confidence interval (CI) 1.506-16.841, p = 0.009], with stages II (HR 3.337, 95% CI 1.701-6.547, p < 0.001) and III (HR 2.445, 95% CI 1.280-4.668, p = 0.007), vs stage I and histological type 2 (HR 1.610, 95% CI 0.938-2.762, p = 0.001). CONCLUSIONS: For endometrial cancer patients requiring surgery, the selection of a more extensive type of hysterectomy did not reduce the rate of local recurrence. Therefore, there is little significance in performing mRH in such cases.

AIM: The human papillomavirus (HPV) vaccination rate in Japan fell to nearly 0% following widespread coverage of possible adverse events. Developing a next approach to promote the effective prevention of HPV-related diseases including cervical cancer (CC) in Japan requires comprehensive understanding of knowledge and attitudes regarding CC prevention, HPV infection and HPV vaccination among the population including laypersons and medical professions in Japan. METHODS: A questionnaire survey was administered in a wide variety of settings in Japan. The questionnaire contained items on knowledge about CC, HPV infection and HPV vaccination; awareness of the HPV vaccine's effectiveness and associated adverse events; and attitudes toward the HPV vaccination for their daughters and for men/boys. RESULTS: Of 3033 targeted people, complete survey responses were received from 1182 men and 1602 women (total: 2784). The male laypersons' group had significantly lower knowledge than did the female laypersons' group (adjusted odds ratio, aOR = 3.86, P < 0.001). Compared with the male laypersons' group, the female laypersons' group tended to have less positive attitudes toward HPV vaccination for their daughters (aOR = 0.78, P = 0.006), but the female laypersons' group showed more positive attitudes toward vaccinating men/boys (aOR = 1.93, P < 0.001). CONCLUSION: The survey results indicated that men in Japan generally lacked knowledge and awareness of HPV-related diseases and their prevention. However, women had more negative attitudes toward HPV vaccination for their daughters than did men. Increasing male involvement in HPV prevention and changing women's perceptions of the HPV vaccine are essential steps to increase the HPV vaccination rate.

BACKGROUND: In Japan, the rate of cervical cancer screening is remarkably low, especially among women in their twenties and thirties, when cervical cancer is now increasing dramatically. The aim of this study was to test whether a modified government reminder for 20-year-old women to engage in cervical cancer screening, acting through maternal education and by asking for a maternal recommendation to the daughter to receive the screening, could increase their participation rate. METHODS: In two Japanese cities, 20-year-old girls who had not received their first cervical cancer screening before October of fiscal year 2014 were randomized into two study arms. One group of 1,274 received only a personalized daughter-directed reminder leaflet for cervical cancer screening. In the second group of 1,274, the daughters and their mothers received a combination package containing the same reminder leaflet as did the first group, plus an additional informational leaflet for the mother, which requested that the mother recommend that her daughter undergo cervical cancer screening. The subsequent post-reminder screening rates of these two study arms were compared. RESULTS: The cervical cancer screening rate of 20-year-old women whose mothers received the information leaflet was significantly higher than that for women who received only a leaflet for themselves (11% vs 9%, P = 0.0049). CONCLUSIONS: An intervention with mothers, by sending them a cervical cancer information leaflet with a request that they recommend that their daughter receive cervical cancer screening, significantly improved their daughters' screening rate.

BACKGROUND: Prior research about the sexual and reproductive health of young women has relied mostly on self-reported survey studies. Thus, participant recruitment using Web-based methods can improve sexual and reproductive health research about cervical cancer prevention. In our prior study, we reported that Facebook is a promising way to reach young women for sexual and reproductive health research. However, it remains unknown whether Web-based or other conventional recruitment methods (ie, face-to-face or flyer distribution) yield comparable survey responses from similar participants. OBJECTIVE: We conducted a survey to determine whether there was a difference in the sexual and reproductive health survey responses of young Japanese women based on recruitment methods: social media-based and conventional methods. METHODS: From July 2012 to March 2013 (9 months), we invited women of ages 16-35 years in Kanagawa, Japan, to complete a Web-based questionnaire. They were recruited through either a social media-based (social networking site, SNS, group) or by conventional methods (conventional group). All participants enrolled were required to fill out and submit their responses through a Web-based questionnaire about their sexual and reproductive health for cervical cancer prevention. RESULTS: Of the 243 participants, 52.3% (127/243) were recruited by SNS, whereas 47.7% (116/243) were recruited by conventional methods. We found no differences between recruitment methods in responses to behaviors and attitudes to sexual and reproductive health survey, although more participants from the conventional group (15%, 14/95) chose not to answer the age of first intercourse compared with those from the SNS group (5.2%, 6/116; P=.03). CONCLUSIONS: No differences were found between recruitment methods in the responses of young Japanese women to a Web-based sexual and reproductive health survey.

AIM: The incidence of non-obstetrical complications after cervical conization is low, and women receive minimal postsurgical attention. In this study, we investigated whether women felt any discomfort after undergoing conization by harmonic scalpel, one of the hot-knife devices widely used in Japan. METHODS: Eighty-eight women aged 20-47 years who were still experiencing menstrual cycles and had undergone harmonic conization participated in a questionnaire survey regarding perisurgical complications and postsurgical changes in gynecological issues. Correlations between the occurrence of postoperative complications and clinical characteristics were analyzed. RESULTS: Regarding the complications immediately after the surgery, 37 women (45.1%) complained of postoperative bleeding that was heavier than their usual menstrual bleeding, and 14 (18.2%) reported that the postsurgical bleeding was greater than they had expected. Regarding long-term gynecological changes after conization, 27 women (30.7%) reported that the duration of menstrual bleeding had increased after the surgery, 20 (22.7%) indicated that pain during menstruation had changed, and 40 (45.5%) stated that the amount of menstrual bleeding had changed. Irregular genital bleeding outside of menstruation appeared in 23 women (26.4%). Additionally, 24 (27.6%) of the women reported that the conization procedure negatively impacted their quality of life. Finally, the occurrence of long-term atypical bleeding after the surgery was significantly correlated with the thickness and circumference of the tissue specimen. CONCLUSION: Several women experienced a significant change in quality of life after harmonic conization. Women who undergo conization should receive a comprehensive preoperative overview of the procedure and attentive postsurgical care.

AIM: Endocervical curettage (ECC) at the time of conization has been reported to be effective for diagnosing cervical intraepithelial neoplasia and/or early stage cervical cancer. We aimed to verify the accuracy of ECC with conization. METHODS: We retrospectively analyzed the records of 540 patients with suspected neoplastic cervical lesions who underwent conization at the Yokohama City University Hospital from January 2008 to December 2015. To validate the effectiveness of ECC for evaluating endocervical lesions, histopathologic findings from ECC samples were compared with those from endocervical specimens obtained by conization. In patients who subsequently underwent hysterectomy, specimens of residual endocervical stump lesions were compared with the specimens obtained by ECC. RESULTS: ECC was performed in 58.9% of patients who underwent conization. Positive findings were only observed in 7.9%, while negative findings were found in 67.3% of ECC samples; however, 24.8% of the samples were inadequate for diagnosis. None of the patients had an upgraded diagnosis according to ECC results. The sensitivity of ECC in predicting endocervical stump lesions that were identified by conization specimens was 25.0%, the specificity was 94.2% and the positive predictive value was 55.0% (κ = 0.238; P < 0.001). ECC samples yielded a sensitivity of 42.9%, a specificity of 83.9%, and positive predictive value of 54.5% (κ = 0.284; P = 0.053) in predicting residual endocervical lesions in the uterus. CONCLUSIONS: As it offers low sensitivity and positive predictive value, ECC at the time of conization is of limited benefit for evaluating endocervical lesions.

Aim: A multicenter, retrospective survey was conducted in order to investigate the current clinical status of adenomyosis in Japan. Methods: The questionnaires covered the management of infertile women with adenomyosis and the outcomes of infertility treatment in women with adenomyosis. The questionnaires were sent to 1149 facilities in Japan. Results: The data were obtained on 535 infertile women with adenomyosis from 190 facilities. Regarding management, infertility treatment was performed without pretreatment for adenomyosis in 37 facilities, after medication in eight facilities, and after an operation in four facilities. Management policies were not established in 106 facilities. Regarding outcomes, the pregnancy rate was 41.7% and the abortion rate was 29.8%. Eighty-five patients received medication and 89 patients underwent surgery as a pretreatment before infertility treatment, while 361 patients had no pretreatment. In relation to the type of adenomyosis, 162 patients had the focal type and 336 patients had the diffuse type. The pregnancy rate and abortion rate were not affected by pretreatment or the type of adenomyosis. Conclusion: The management policy for infertile women with adenomyosis has not been established. The pregnancy rate of infertility treatment is about 40%. There were no data to suggest that medication or surgery as a pretreatment for adenomyosis increased the pregnancy rate in infertile women.
RESUMO
Purpose: To investigate the impact of adenomyosis on the complications and outcomes of pregnancy in Japan. Methods: We carried out a multicenter retrospective questionnaire survey. A questionnaire regarding pregnancy complications and the outcomes of pregnancy was sent to 725 facilities. Results: Data were obtained on the cases of 272 pregnant women with adenomyosis from 65 facilities. The complications of pregnancy included miscarriage before 12 weeks of pregnancy (14.8%), miscarriage after 12 weeks of pregnancy (9.9%), preterm delivery (24.4%), fetal growth restriction (11.8%), pregnancy-induced hypertension (9.9%), intrauterine infection (7.3%), and cervical incompetency (5.3%). The rates of pregnancy complications in the three groups classified according to pretreatment for adenomyosis (no pretreatment, medication, surgery) did not differ to a statistically significant extent. The rates of miscarriage (>12 weeks) and cervical incompetency increased according to the size of the adenomyosis. The rates of pregnancy-induced hypertension and uterine infection in patients with diffuse-type adenomyosis were higher than that in patients with focal-type adenomyosis. Conclusions: Our results show that the increased size and diffuse type of adenomyosis are associated with adverse pregnancy outcome. We should be aware of the higher incidence of pregnancy-induced hypertension and uterine infection in patients with diffuse-type adenomyosis.
RESUMO
Atypical protein kinase C λ/ι (aPKCλ/ι) is a regulator of epithelial cellular polarity. It is also overexpressed in several cancers and functions in cell proliferation and invasion. Therefore, we hypothesized that aPKCλ/ι may be involved in development and progression of cervical intraepithelial neoplasia (CIN), the precancerous disease of cervical cancer induced by human papillomavirus. To do this, we investigated the relationship between aPKCλ/ι expression and CIN. aPKCλ/ι expression level and subcellular localization were assessed in 192 CIN biopsy samples and 13 normal epithelial samples using immunohistochemistry. aPKCλ/ι overexpression (normal epithelium, 7.7%; CIN1, 41.7%; CIN2/3, 76.4%) and aPKCλ/ι nuclear localization (normal epithelium, 0.0%; CIN1, 36.9%; CIN2/3, 78.7%) were higher in CIN samples than normal samples (P<0.05), suggesting that CIN grade is related to aPKCλ/ι overexpression and nuclear localization. Then, 140 CIN cases were retrospectively analyzed for 4-yr cumulative disease progression and regression rates using the Cox proportional hazards model. CIN1 cases with aPKCλ/ι overexpression or aPKCλ/ι nuclear localization had a higher progression rate than CIN1 cases with normal aPKCλ/ι expression levels or cytoplasmic localization (62.5% vs. 9.7% and 63.1% vs. 9.4%, respectively; P<0.001). Multivariate analysis indicated that human papillomavirus types 16 and 18, aPKCλ/ι overexpression (hazard ratio=4.26; 95% confidence interval, 1.50-12.1; P=0.007), and aPKCλ/ι nuclear localization (hazard ratio=3.59; 95% confidence interval, 1.24-10.4; P=0.019) were independent risk factors for CIN1 progression. In conclusion, aPKCλ/ι could be useful for the therapeutic management of patients with CIN, particularly those with non-human papillomavirus 16/18 types.
