Annual Report 2020

Department of Gynecology

Tomoyasu Kato, Mitsuya Ishikawa, Masaya Uno, Yasuhito Tanase, Mayumi Kato

Introduction

 The Department of Gynecology deals with tumors originating from the female genital and reproductive organs. Surgery is the main treatment modality for most gynecologic cancers, but multidisciplinary treatments consisting of radiotherapy and chemotherapy are routinely considered in close cooperation with therapeutic radiation oncologists and medical oncologists. The incidences of three common gynecologic cancers, that is, cervical, endometrial and ovarian/tubal/peritoneal cancer, are still on the rise in Japan. We are also working on the diagnosis of and surgery for rare cancers in gynecology.

The Team and What We Do

 In June 2019, we began performing full-scale laparoscopic surgery, and we are now in our second year. The number of cases has been steadily increasing and we have ensured patient safety and have been certified as a gynecological endoscopy facility. In addition, the da Vinci procedure, which we started performing in March 2020, has been used for both benign and uterine cancer surgeries and it qualified for insurance coverage by the end of the fiscal year.

 The number of surgeries performed this fiscal year was 276, a decrease of 13 from last year. The number of surgeries decreased in early spring during the COVID-19 pandemic, but has since recovered.

 The primary surgical sites are shown in Table 1. The increase in vulvar cancer and uterine sarcoma can be attributed to the large number of patients referred from the Rare Cancer Center. The breakdown of surgical procedures was 19 cases of wide hysterectomy and 19 cases of paravalvular lymph node dissection, a decrease from last year, but an increase in MIS (minimally invasive surgery) cases (Table 2).

Research activities

 Although many institutions nationwide provide adjuvant treatment for intermediate recurrence risk of cervical cancer, we do not. We reported the results of our treatment and the reduced need for adjuvant treatment for squamous cell carcinoma (Yoneoka Y, et al. Obstet Gynecol Sci. 64:226,2021). We are planning to compare the results with those of institutions that provide the adjuvant treatment.

Clinical trials

JCOG

1) A nonrandomized confirmatory trial of modified radical hysterectomy for patients with FIGO Stage Ib1 (< 2 cm) uterine cervical cancer (JCOG1101) has been completed and is in the follow-up period.

2) A non-randomized verification study regarding selection of fertility-sparing surgery for patients with epithelial ovarian cancer (JCOG1203) is ongoing as planned.

3) A randomized phase II/III trial of conventional paclitaxel and carboplatin versus dose-dense paclitaxel and carboplatin in stage IVB, recurrent, or persistent cervical carcinoma (JCOG 1311) has been completed and is in the follow-up period.

4) A non-randomized confirmatory trial of postoperative concurrent chemotherapy (CCRT) using IMRT for patients with curatively resected high-risk uterine cervical cancer (JCOG1402) is ongoing as planned.

5) A randomized phase III trial to confirm the survival effect of para-aortic lymphadenectomy for patients with endometrial cancer (JCOG1412) is ongoing as planned.

GOTIC

6) GOTIC-VTE trial/GOTIC-015: A multicenter seamless prospective cohort study and single-arm confirmatory clinical trial for the venous thromboembolism in gynecological cancer patients has been completed and is under analysis.

7) GOTIC-019: Retrospective study about the application of neoadjuvant chemotherapy followed by interval debulking surgery for patients with advanced epithelial ovarian cancer has been completed and is submitted.

Education

 Dr. Yoneoka, who completed his chief residency in March, passed the gynecologic oncologist exam. Dr. Natsume and Dr. Kitamura joined us for the first year of the three-year course, with Dr. Fujii being in the second year.

Future Prospects

 We will educate and pass on to future generations the fact that our department's surgical results are better than those of other institutions and that this outcome is due to our surgical skills.
