RESUMO
BACKGROUND: We conducted this study to clarify the magnetic resonance imaging (MRI) characteristics of lobular endocervical glandular hyperplasia (LEGH) and Nabothian cysts. METHODS: This study included 48 patients who underwent hysterectomy at our institution between 2016 and 2020 for suspected LEGH. Histopathological studies confirmed the presence of 25 Nabothian cysts and 23 cases of LEGH. We retrospectively analyzed five characteristic MRI findings: (1) located at the upper cervical canal, (2) positioned within the cervical stroma, (3) not circumscribing the cervical canal, (4) low- to iso-intensity on T1-weighted images (T1WI), and (5) "cosmos" or "microcystic" pattern. We compared the diagnostic accuracy of these findings for LEGH and Nabothian cysts using sensitivity, specificity, and predictive values. Combinations of findings were also calculated. RESULTS: The characteristics "cosmos" or "microcystic" pattern, lesion not circumscribing the cervical canal, and low/iso-intensity on T1WI had a sensitivity and specificity greater than 50%. The sensitivity was 73.9% and specificity 84.0% when a combination of "cosmos" or "microcystic" pattern and lesion not circumscribing the cervical canal was present. CONCLUSION: The coexistence of a "cosmos" or "microcystic" pattern and not circumscribing the cervical canal was the most characteristic finding that distinguished LEGH from Nabothian cysts. When neither of these findings is present, Nabothian cyst can be suspected.

AIM: Ovarian surveillance in women with hereditary breast and ovarian cancer who do not undergo risk-reducing salpingo-oophorectomy has been controversial. Therefore, this study aimed to demonstrate the clinical features of ovarian surveillance at our institution using a technique that combines serum cancer antigen 125 measurements, transvaginal ultrasonography, and uterine endometrial cytology. METHODS: We retrospectively examined 65 women, who had not undergone risk-reducing salpingo-oophorectomy diagnosed with hereditary breast and ovarian cancer between 2000 and 2021 at our hospital. Clinical information was obtained and analyzed through a chart review. The details of the treatment course were reviewed for patients who had developed ovarian cancer. RESULTS: Overall, 5 of the 65 women were diagnosed with ovarian cancer based on abnormal findings during periodic surveillance. All patients who developed ovarian cancer were asymptomatic, even if the cancer was at an advanced stage. Two of the 65 patients had endometrial cytology abnormalities, both of whom had ovarian cancer. All patients who developed ovarian cancer underwent primary debulking surgery, and complete gross resection was achieved. None of the patients experienced ovarian cancer recurrence. CONCLUSIONS: The ovarian surveillance strategy at our institution for women with hereditary breast and ovarian cancer who do not undergo risk-reducing salpingo-oophorectomy can identify asymptomatic ovarian cancer and contribute to achieving complete gross resection during primary surgery. Ovarian surveillance may contribute to a reduction in ovarian cancer mortality.

Pelvic exenteration (PE) is a highly invasive procedure associated with high morbidity and mortality rates. Laparoscopy is a promising option to reduce this invasiveness, and laparoscopic PE significantly reduces blood loss and shortens hospital stays. In the case of a large tumor with invasion to the surrounding organs, laparoscopic dissection around the pelvic floor is sometimes problematic owing to restrictions on handling instruments. To overcome these limitations, we performed a transperineal endoscopic approach using the GelPOINT V-path in addition to laparoscopic PE. This approach enabled dissection around the pelvic floor without the abovementioned obstacles under magnified visualization. As a result, we could dissect the pelvic floor precisely with a reduction of the dead pelvic space, which might contribute to reduced rates of postoperative complications while ensuring oncologic outcomes.
RESUMO
The therapeutic effects of molecular targeted drugs are, in some cases, more pronounced than those of conventional chemotherapy, and their introduction as a standard treatment is increasing. The present report describes a case of ovarian insufficiency in a young woman caused by tyrosine kinase inhibitor lenvatinib. The 25-year-old woman received lenvatinib (8 mg/day) for 98 days as preoperative chemotherapy for hepatocellular carcinoma. Blood testing the day before starting lenvatinib administration indicated 4.40 mIU/ml luteinizing hormone (LH), 5.2 mIU/ml follicle-stimulating hormone (FSH) and age-equivalent hormone values. Amenorrhea occurred after the start of administration, and 48 days later, the LH level was 41.8 mIU/ml and the FSH level was 44 mIU/ml, indicating a decrease in ovarian function. The patient underwent hepatectomy, and 49 days after the end of lenvatinib administration, the LH level had improved to 4.5 mIU/ml and the FSH level had improved to 2.5 mIU/ml. After the hepatectomy, the patient began to have regular menstrual cycles once again. Ovarian toxicity has not been recognized as a side effect of lenvatinib. However, the present report describes primary ovarian insufficiency considered to be caused by this drug. Potential damage to ovarian function may need to be considered when molecular targeted drugs with the same mechanism of action as lenvatinib are used in young women.
RESUMO
OBJECTIVE: The efficacy of intra-abdominal cytoreductive surgery in patients with endometrial cancer and distant metastasis is equivocal. We investigated the effectiveness of such surgical treatment and whether it should be performed before or after chemotherapy (CT). METHODS: This study included patients with an International Federation of Gynecology and Obstetrics stage IVB endometrial cancer who received initial treatment at our hospital between January 2006 and December 2017. RESULTS: We retrospectively reviewed 67 patients with stage IVB endometrial cancer with distant metastases and classified them into preceding surgery (PS, n=23), chemotherapy followed by a surgery (CS, n=27), and CT (n=17) groups. We examined the achievement of resection with [R (1)] or without [R (0)] intra-abdominal macroscopic residue and survival. The median survival time for R (0) was 44 (95% confidence interval [CI]=9-not available [NA]) months in the PS group and 27 (95% CI=11-NA) months in the CS group. The median survival time for R (1) was 9 (95% CI=0-24) months in the PS group and 12 (95% CI=7-19) months in the CS group. The similar prognosis in both groups was worse with R (1) than with R (0). The survival curve for R (1) in the resection groups was similar to that of the CT group. CONCLUSION: Achieving resection without intra-abdominal macroscopic residue for endometrial cancer with distant metastases, whether before or after CT, could extend patients' survival.

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.

To determine the impact of the coverage of risk-reducing salpingo-oophorectomy (RRSO) and mastectomy (RRM) as well as genetic testing for BRCA pathogenic variants by the national insurance system in Japan. We compared the clinical background of women who underwent RRSO at our institution before and after its coverage by the national insurance system. Those who underwent RRSO between January 2017 and December 2019 and between April 2020 and March 2022 were classified as Period. A and B, respectively. Overall, 134 women underwent RRSO during the study period. In Period A and B, 45 and 89 women underwent RRSO for the study period was 36 and 24 months, respectively. Compared with Period A, the number of women who underwent RRSO per month increased by threefold in Period B (p < 0.01). In addition, the number of women who underwent surgery for breast cancer along with RRSO increased in Period B (p < 0.01). Although the number of women who underwent concurrent RRM with RRSO in Period B increased, the difference was not statistically significant. Compared with Period A, the number of women diagnosed with BRCA pathogenic variant increased by 3.9-fold, and the proportion of women who underwent concurrent hysterectomy at the time of RRSO decreased from 66 to 7.9% in Period B (p < 0.01). Owing to the introduction of the national insurance system, the number of women who underwent RRSO and concurrent surgery for breast cancer at the time of RRSO increased in Japan.

Background: One of the major risks of preterm birth is a history of conization. However, the risk of infection due to this procedure is still not well known. Using next-generation sequencing, we aimed to reveal the influence of conization on vaginal microbiota in the following pregnancy, and their relationship between spontaneous preterm birth (sPTB). Methods: We conducted a prospective cohort study including 133 pregnant patients, of whom 25 had conization histories and 108 did not. Vaginal microbiome samples were collected using swabs by an obstetrician upon inclusion in the first trimester and during delivery. V1-V2 of the 16S rRNA gene were amplified and analyzed to identify the bacteria. Results: The conization group had a significantly lower delivery week (34 weeks vs. 36 weeks, p = 0.003) and higher sPTB rate (64% vs. 8.3%, p ≤ 0.001) than the control group. In the conization group, alpha (Chao 1, p = 0.02; phylogenetic diversity whole tree, p = 0.04) and beta diversity (permutational multivariate analysis of variance test, p = 0.04) of the vaginal microbiota was significantly higher during delivery in patients who delivered preterm than in those who delivered term. Community-state type IV in the first trimester was significantly associated with sPTB (overall odds ratio 3.80, 95% confidence interval 1.33-10.8, p = 0.01). Conclusions: Conization is a risk factor for sPTB. Increased risk of sPTB in patients after conization may belong to the vulnerable defense mechanism, due to the shortened cervix and decreased cervical mucus.

BACKGROUND/AIM: Pelvic lymph node (LN) metastases are found histopathologically after radical hysterectomy (RH) in some cases of cervical adenocarcinoma with no enlarged LNs on preoperatively. The aim was to clarify whether LN metastasis is a prognostic factor in these patients, and whether any postoperative therapy is advisable. PATIENTS AND METHODS: Sixty-one patients with stage I-II cervical adenocarcinoma [International Federation of Obstetrics and Gynecology (FIGO) 2008] with no enlarged pelvic LNs on preoperative imaging evaluation who underwent RH at our institution were retrospectively examined for clinicopathological, treatment, and prognosis-related factors. RESULTS: The median age was 47 years. FIGO stages were IB1 in 44 patients, IB2 in 10, IIA in 4, and IIB in 3. Seventeen patients (27.9%) had positive pelvic LNs. The multivariate analysis for both overall (OS) and disease-free (DFS) survival showed only pelvic LN metastasis was an independent prognostic factor. In a multivariate analysis of LN-positive cases, multiple LN metastases was an independent prognostic factor for poorer DFS. OS rates were 100%, 83.3%, and 30.0%, and DFS rates were 85.5%, 83.3%, and 12.5% for patients with no LN metastasis, single metastasis, and multiple metastases, respectively, showing a significant difference. Eight recurrences were observed in 10 patients with multiple node-positive disease, and six (75%) had an intrapelvic recurrence. CONCLUSION: Among patients who underwent RH for cervical adenocarcinoma with no preoperative enlarged LN and positive pelvic LNs confirmed postoperatively, multiple positive pelvic LNs are an independent poor prognostic factor. Because pelvic recurrence is common, concurrent chemoradiotherapy, possibly using paclitaxel and cisplatin, should be considered as adjuvant therapy.
RESUMO
Radical hysterectomy is a standard surgery to treat early-stage uterine cervical cancer. The Laparoscopic Approach to Cervical Cancer (LACC) trial has shown that patients receiving minimally invasive radical hysterectomy have a poorer prognosis than those receiving open radical hysterectomy; however, the reason for this remains unclear. The LACC trial had 2 concerns: the learning curve and the procedural effects. Appropriate management of the learning curve effect, including surgeons' skills, is required to correctly interpret the result of surgical randomized controlled trials. Whether the LACC trial managed the learning curve effect remains controversial, based on the surgeons' inclusion criteria and the distribution of institutions with recurrent cases. An appropriate surgical procedure is also needed, and avoiding intraoperative cancer cell spillage plays an important role during cancer surgery. Cancer cell spillage during minimally invasive surgery to treat cervical cancer is caused by several factors, including 1) exposure of tumor, 2) the use of a uterine manipulator, and 3) direct handling of the uterine cervix. Unfortunately, these issues were not addressed by the LACC trial. We evaluated the results of minimally invasive radical hysterectomy while avoiding cancer cell spillage for early-stage cervical cancer. Our findings show that avoiding cancer cell spillage during minimally invasive radical hysterectomy may ensure an equivalent oncologic outcome, comparable to that of open radical hysterectomy. Therefore, evaluating the importance of avoiding cancer cell spillage during minimally invasive surgery with a better control of the learning curve and procedural effects is needed.

OBJECTIVE: The role of Lactobacillus-dominant microbiota in the endometrium in reproductive function is unclear. We therefore aimed to explore the impact of the balance of Lactobacillus and pathological bacteria in the endometrial and vaginal microbiomes on the pregnancy outcomes of women treated with assisted reproductive technology (ART). METHODS: This study included 35 women with infertility submitted to good-quality embryo transfers. The cutoff values for abundance of Lactobacillus species (spp.) and pathological bacteria in the endometrium and vagina were calculated. Women with Lactobacillus spp. and pathological bacteria abundance above the cutoff values were categorized in the high-abundance group, whereas those with abundance below cutoff values were categorized in the low abundance group. We divided the patients into four groups based on the combination of high/low abundance of Lactobacillus spp. and pathological bacteria. RESULTS: The 35 cases of good-quality embryo transfer resulted in 21 pregnancies. Pregnant women were present in significantly higher proportions in the high Lactobacillus spp. abundance and low pathological bacteria abundance group, whereas the opposite combination (i.e., low Lactobacillus spp. abundance and high pathological bacteria abundance) saw a significantly higher proportion of nonpregnant women (p=0.022). CONCLUSIONS: The balance between Lactobacillus and pathological bacterial abundance in the endometrial and vaginal microbiomes is associated with pregnancy from ART.

OBJECTIVES: A high rate of preterm birth has been reported in Okinawa Prefecture, the southernmost island prefecture of Japan. Hence, this study aimed to identify the risk factors for preterm birth in this prefecture. METHODS: This retrospective study included data from January 2013 to December 2019 from three facilities in Okinawa Prefecture. Of 13,468 cases of preterm birth at ≥ 22 weeks of gestation, 11,868 were included in this study. Stillbirth and multiparity cases were excluded. First, we compared the overall preterm and full-term birth groups by categorizing the patient background, obstetric, and fetal risk factors. Further, we categorized preterm births into three groups (22-27, 28-33, and 34-36 weeks of gestation) and examined patient background factors to identify potential risk factors for the occurrence of preterm birth in each group. RESULTS: Preterm births accounted for 21.2% (2,521 cases) of all cases, with the rates of 2.6% (317 cases), 6.7% (800 cases), and 11.8% (1,404 cases) at 22-27, 28-33, and 34-36 weeks of gestation, respectively. To prevent preterm birth in Okinawa Prefecture, the present study specifically focused on patient background characteristics. In the multinomial logistic regression, the risk factors for preterm birth at 22-27 weeks of gestation were previous preterm birth (P < 0.0001) and lower age (P = 0.026); at 28-33 weeks of gestation, the risk factors were previous preterm birth (P < 0.0001) and history of cervical conization (P = 0.009); and at 34-36 weeks of gestation, only previous preterm birth (P < 0.0001) was a risk factor. CONCLUSIONS FOR PRACTICE: Previous preterm birth, younger age, and history of cervical conization were risk factors for Preterm birth in Okinawa. To reduce premature births in Okinawa Prefecture, it is important to pick up women with these risk factors and provide them with appropriate guidance and education on an ongoing basis.

Bladder pseudoexstrophy is a rare form of bladder exstrophy. Bladder exstrophy occurs in 1 in every 30,000 to 50,000 live births. Because bladder pseudoexstrophy is asymptomatic, it may be undiagnosed even in adulthood. A 31-year-old woman with uterus bicornis unicollis and a low-set umbilicus underwent emergency cesarean delivery during the 37th week of pregnancy for chorioamnionitis. Perioperatively, asymptomatic anatomical abnormalities were identified, which included separated rectus abdominis muscles and diastasis of the symphysis pubis. The urinary tract was normal. The patient was diagnosed with bladder pseudoexstrophy. A low-set umbilicus may be a potential marker for the diagnosis of bladder pseudoextrophy.
RESUMO
BACKGROUND/AIM: To investigate sarcopenia as a predictor of prognosis before concurrent chemoradiotherapy (CCRT) in patients with squamous cell carcinoma (SCC) of the cervix using the new psoas muscle index (PMI) cutoff value for sarcopenia in Japanese women. PATIENTS AND METHODS: We included 134 patients with SCC of the cervix treated with CCRT. CT images were taken within one month before treatment. Measurements of PM and skeletal muscle (SM) area were taken at the L3 level using a CT image analysis system (Synapse Vincent). Whole-pelvic external beam radiotherapy (EBRT) with 50 Gy was performed. High-dose-rate intracavitary brachytherapy and boost EBRT doses were administered. The patients received 40 mg/m2 of cisplatin weekly during CCRT. Kaplan-Meier analysis and the log-rank test were used to compare survival rates. RESULTS: The five-year overall survival (OS) and five-year progression-free survival of all 134 patients were 86.1% and 77.3%, respectively. Univariate analysis revealed that only PMI had a significant association with OS (PMI <3.92 cm2/m2 in the sarcopenia group vs. PMI ≥3.92 cm2/m2 in the non-sarcopenia group, p=0.0112), with no significant differences in age, advanced stage of disease, tumor size, lymph node enlargement, serum SCC, or SMI. Multivariate analysis revealed that PMI is the only independent prognostic factor for OS, but none of the factors were found to have a significant association with PFS. CONCLUSION: PMI as an indicator of sarcopenia was found to be an independent prognostic factor for patients with SCC of the cervix who underwent CCRT.

Objective: It is well known that power morcellation of unexpected uterine sarcoma affects prognosis. There are few reports on the effects of scalpel morcellation or myomectomy of uterine sarcoma on prognosis, which is not well understood. This study investigated the effect on recurrence and prognosis when tumors of uterine sarcoma undergo scalpel morcellation or myomectomy. Methods: We performed a retrospective, observational study by collecting data from the medical records of patients who were histologically diagnosed with uterine sarcoma at our hospital between 2005 and 2017. All patients with unexpected uterine sarcoma were diagnosed after laparoscopic hysterectomy with scalpel morcellation or myomectomy (abdominal and laparoscopic) for presumed myoma. We evaluated recurrence rate, recurrence site, progression-free survival (PFS), and overall survival (OS). Results: A total of 15 patients were examined in this study. Twelve patients underwent myomectomy (7 patients with open surgery, 5 patients with laparoscopic surgery), and 3 patients underwent total laparoscopic hysterectomy with transvaginal scalpel morcellation. There were 11 cases of recurrence, and the recurrence rate was 78 %. The recurrence site was peritoneal dissemination in 10 cases (91 %) and lymph node metastasis in 1 case (9 %). The median PFS was 32 months [95 % confidence interval (CI) = 6.5-NA], and the median OS was 95.5 months [95 % CI = 55.8-NA]. Conclusion: Power morcellation, scalpel morcellation, and myomectomy may affect recurrence and prognosis. Further studies are needed in the future.
RESUMO
Ovarian cysts develop rarely in fetuses during pregnancy and usually disappear after birth. However, during pregnancy, torsion and rupture of the cyst can occur and it is necessary to manage such cases. At present, there is no standardized prenatal or neonatal treatment. However, the preservation of ovarian function is an important consideration. Here, we present a case involving a 35-year-old woman who gave birth to an infant with a complicated ovarian cyst, which was resolved through laparoscopic surgery on the third day after birth. The prenatal diagnosis of the fetal ovarian cyst was performed prenatally using ultrasound and magnetic resonance imaging (MRI). However, torsion of the ovarian pedicle was suspected because of dorsal thickening of the cyst wall and fluid formation indicated by high intensity on T1- and T2-weighted MRI. Surgery was complicated due to involvement in the torqued pedicle of the left fallopian tubal fimbria, which was released. The cyst was drained and partially resected, and then the pedicle torsion was released. By four years and five months of follow-up, there had been no ovarian cyst findings on ultrasound or MRI. Larger cysts are more likely to involve torsion of the ovarian pedicle and potential bleeding. Considering that, in this case, the cyst was large and proved to be ischemic-hemorrhagic, the decision to operate seemed justified.
RESUMO
Although geographical differences in the distribution of human papillomavirus genotypes have been observed worldwide, no studies have reported on national differences in the prevalence of human papillomavirus types in Japan. Here, we report a cross-sectional study to explore regional differences in the prevalence of human papillomavirus types among Japanese women with cervical intraepithelial neoplasia or invasive cervical cancer. Using human papillomavirus genotyping data from the nationwide prospective study on human papillomavirus vaccine effectiveness, we compared the frequency of detection of 15 high-risk and two low-risk human papillomavirus types in each disease category between the women who visited hospitals located in eastern Japan and those who visited hospitals located in western Japan. The risk of cervical intraepithelial neoplasia progression was assessed by calculating a prevalence ratio of each human papillomavirus type for cervical intraepithelial neoplasia grade 2/3 versus grade 1. Among the human papillomavirus types studied, human papillomavirus 52 was detected significantly more frequently in western hospitals than in eastern hospitals in cervical intraepithelial neoplasia grade 1 patients, but was less frequent in cervical intraepithelial neoplasia grade 2/3. The prevalence of particular human papillomavirus types was not significantly different between patients in hospitals in eastern Japan and those in hospitals in western Japan for invasive cervical cancer. In both eastern and western hospitals, a higher risk of cervical intraepithelial neoplasia progression was observed in patients infected with human papillomavirus 16, 31 or 58. In contrast, there was a significantly higher prevalence of human papillomavirus 52 infection in women with cervical intraepithelial neoplasia grade 2/3 than in those with cervical intraepithelial neoplasia grade 1 in eastern hospitals (prevalence ratio, 1.93; 95% confidence interval, 1.48-2.58), but not in western hospitals (prevalence ratio, 1.03; 95% confidence interval, 0.83-1.30). Regional differences of human papillomavirus 52 prevalence in cervical intraepithelial neoplasia lesions may exist and emphasize the importance of continuous monitoring of human papillomavirus type prevalence throughout the country in order to accurately assess the efficacy of human papillomavirus vaccines.

Pembrolizumab plus chemotherapy with or without bevacizumab demonstrated prolonged progression-free survival (PFS) and overall survival (OS) versus chemotherapy in patients with persistent, recurrent, or metastatic cervical cancer in the phase 3, randomized, double-blind, placebo-controlled KEYNOTE-826 study. We report outcomes in patients enrolled in Japan. Patients received pembrolizumab 200 mg or placebo Q3W for up to 35 cycles plus chemotherapy (paclitaxel 175 mg/m2 + cisplatin 50 mg/m2 or carboplatin AUC 5) with or without bevacizumab 15 mg/kg. Dual primary endpoints were PFS per RECIST v1.1 by investigator assessment and OS in the global population; these were evaluated in patients with tumors with PD-L1 combined positive score (CPS) ≥1, all-comers, and PD-L1 CPS ≥10. Fifty-seven patients from Japan were randomized (pembrolizumab plus chemotherapy, n = 35; placebo plus chemotherapy, n = 22). Pembrolizumab plus chemotherapy improved PFS versus placebo plus chemotherapy in patients with PD-L1 CPS ≥1 (n = 51; hazard ratio [HR; 95% CI], 0.36 [0.16-0.77]), all-comers (n = 57; 0.45 [0.22-0.90]), and patients with PD-L1 CPS ≥10 (n = 25; 0.36 [0.12-1.07]). HRs (95% CI) for OS were 0.38 (0.14-1.01), 0.41 (0.17-1.00), and 0.37 (0.10-1.30), respectively. Incidence of grade 3-5 AEs was 94% in the pembrolizumab group and 100% in the placebo group. Consistent with findings in the global KEYNOTE-826 study, pembrolizumab plus chemotherapy with or without bevacizumab may prolong survival versus placebo plus chemotherapy with or without bevacizumab and had a manageable safety profile in Japanese patients with persistent, recurrent, or metastatic cervical cancer.
