    　View Summary

    AIM: The importance of human papillomavirus (HPV) co-testing using physician-, self-, and urine-collected samples to predict cervical intraepithelial neoplasia (CIN) grade 1-2 prognoses has not been previously reported. Therefore, this study aimed to investigate outcomes of patients with CIN 1-2 who simultaneously underwent physician-, self-, and urine-collection sampling tests. METHODS: This study was conducted in Japan between October 2019 and November 2022 and examined the proportion of cases with CIN 1-2 progressions, the percentage of cases with persistent CIN 1-2, and the outcome differences according to the results of physician-, self-, and urine-sampling tests. RESULTS: There were 105 and 59 CIN 1 and 2 cases, respectively, with progression or persistence in 27 (29.3%) and 21 (50.0%) cases, respectively. The median follow-up was 20 and 12 months, respectively. Progression and persistence of CIN 1 were significantly associated with HPV-positive physician- and self-collected samples. No significant difference was observed between cases with CIN 2 who had HPV-positive and HPV-negative results using any sampling method. CONCLUSIONS: Physician- and self-testing for HPV are crucial for predicting disease progression risk in CIN 1 cases. Future research with an extended observation period and consideration of the progression risks is warranted.

  • Successful Outcome of Stage IB3 Cervical Cancer Treated With Neoadjuvant Chemotherapy Followed by Vaginal Radical Trachelectomy: A Case Report.

    　View Summary

    Vaginal trachelectomy, which involves resecting the cervix and its parametrium, is a fertility-sparing option for the treatment of early-stage cervical cancer. Although no consensus has been reached on whether simple or radical trachelectomy is preferable, the vaginal approach is typically avoided for tumors larger than 2 cm due to concerns about recurrence. However, some evidence suggests that fertility preservation may still be viable for select patients with larger tumors. This case report describes a woman with bulky cervical cancer who wished to preserve her fertility. After undergoing neoadjuvant chemotherapy (NAC) and vaginal radical trachelectomy (VRT), she achieved a favorable oncological and perinatal outcome, successfully giving birth to a near-full-term baby. The report outlines the patient's management before, during, and after the procedure, including perinatal care. While careful selection of candidates is crucial, accumulating case reports and future trials are expected to shed more light on this treatment approach.

  • Step-by-step demonstration of "sciatic-nerve-preserved beyond-LEER" in a Thiel-embalmed cadaver: a novel salvage surgery for recurrent gynecologic malignancies.

    　View Summary

    OBJECTIVE: Complete resection is the curative treatment choice for recurrent gynecological malignancies. Laterally extended endopelvic resection (LEER) is an effective surgical salvage therapy for lateral recurrence. However, when a recurrent tumor occupies the ischial spine and sacrum, LEER is not indicated, and surgical salvage therapy is abandoned. Theoretically, complete resection of such a tumor is possible by additional pelvic bone resection along with the standard LEER. Nevertheless, owing to the anatomical complexities of the beyond-LEER procedure, 2 major issues should be solved: sciatic nerve injury and tumor disruption during pelvic bone amputation. To overcome these technical challenges, we applied a multidirectional beyond-LEER approach, a novel salvage surgical procedure, with an aim of demonstrating its technical feasibility. METHODS: We created a simulation model of a laterally recurrent tumor that occupied the right ischial spine and sacrum in a Thiel-embalmed cadaver. RESULTS: Multidirectional approaches, including laparoscopic, perineal, and dorsal phases, were safely applied. We laparoscopically marked the L4-L5-S1 complex and S2 nerve with different colored tapes, and by pulling them out into a dorsal surgical field, the sciatic nerve was safely preserved. The dissection lines of the multidirectional approaches were aligned using tapes as landmarks, and complete tumor clearance without tumor disruption was accomplished. By following the cadaveric training, the first laparoscopic-assisted beyond-LEER procedure was successfully performed in a patient with recurrent ovarian cancer. CONCLUSION: Using a Thiel-embalmed cadaver, we demonstrated the technical feasibility of a sciatic nerve-preserved beyond-LEER procedure, which was successfully performed in a patient with recurrent ovarian cancer.
