Abstract Japan is lagging in cervical cancer prevention. The effectiveness of a self‐sampling human papillomavirus (HPV) test, a possible measure to overcome this situation, has not yet been evaluated. A randomized controlled trial was performed to evaluate the effectiveness of a self‐sampling HPV test on detection of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) and screening uptake. Women between 30 and 58 years old who did not participate in the cervical cancer screening program for ≥3 years were eligible and assigned to the intervention group (cytology or self‐sampling HPV test) or control group (cytology). Participants assigned to the intervention group were sent a self‐sampling kit according to their ordering (opt‐in strategy). A total of 7337 and 7772 women were assigned to the intervention and control groups, respectively. Screening uptake in the intervention group was significantly higher than that in the control group (20.0% vs. 6.4%; risk ratio: 3.10; 95% confidence interval [CI]: 2.82, 3.42). The compliance rate with cytology triage for HPV‐positive women was 46.8% (95% CI: 35.5%, 58.4%). CIN2+ was detected in five and four participants in the intervention and control groups, respectively; there was no difference for intention‐to‐screen analysis (risk ratio: 1.32; 95% CI: 0.36, 4.93). Self‐sampling of HPV test increased screening uptake; however, no difference was observed in the detection of CIN2+, probably due to the low compliance rate for cytology triage in HPV‐positive women. Efforts to increase cytology triage are essential to maximize precancer detections.

OBJECTIVE: Therapy-related myeloid neoplasms (t-MNs) are often fatal and arise as late complications of previous anticancer drug treatment. No single-center case series has examined t-MNs in epithelial ovarian cancer (EOC). METHODS: All patients with EOC treated at Chiba University Hospital between 2000 and 2021 were included. We retrospectively analyzed the characteristics, clinical course, and outcomes of patients who developed t-MNs. RESULTS: Among 895 cases with EOC, 814 cases were treated with anticancer drugs. The median follow-up period was 45 months (interquartile range, 27-81) months. Ten patients (1.2%) developed t-MNs (FIGO IIIA in one case, IIIC in three, IVA in one, and IVB in five). Nine patients were diagnosed with myelodysplastic syndrome and one with acute leukemia. One patient with myelodysplastic syndrome developed acute leukemia. The median time from the first chemotherapy administration to t-MN onset was 42 months (range, 21-94 months), with t-MN diagnoses resulting from pancytopenia in four cases, thrombocytopenia in three, and blast or abnormal cell morphology in four. The median number of previous treatment regimens was four (range, 1-7). Paclitaxel + carboplatin therapy was administered to all patients, gemcitabine and irinotecan combination therapy to nine, bevacizumab to eight, and olaparib to four. Six patients received chemotherapy for t-MN. All patients died (eight cancer-related deaths and two t-MN-related deaths). None of the patients was able to restart cancer treatment. The median survival time from t-MN onset was 4 months. CONCLUSIONS: Patients with EOC who developed t-MN were unable to restart cancer treatment and had a significantly worse prognosis.

Twelve years after the first edition of The Guideline for Gynecological Practice, which was jointly edited by The Japan Society of Obstetrics and Gynecology and The Japan Association of Obstetricians and Gynecologists, the 5th Revised Edition was published in 2023. The 2023 Guidelines includes 5 additional clinical questions (CQs), which brings the total to 103 CQ (12 on infectious disease, 30 on oncology and benign tumors, 29 on endocrinology and infertility and 32 on healthcare for women). Currently, a consensus has been reached on the Guidelines, and therefore, the objective of this report is to present the general policies regarding diagnostic and treatment methods used in standard gynecological outpatient care that are considered appropriate. At the end of each answer, the corresponding Recommendation Level (A, B, C) is indicated.
