Background:
Treatment strategies based on histological subtypes are unestablished.
Aims:
Rethinking the significance of surgery for uterine cervical cancer.
Methods:
Using the database of cervical cancer stages IB-IIB with extensive hysterectomy (Federation of Gynecology and Obstetrics [FIGO] 2008) established by the Japanese Gynecologic Oncology Group network, we conducted a clinicopathological study of cervical cancer cases reclassified according to the FIGO 2018 staging. In stage IB (FIGO 2018) cervical cancer patients, there was no significant difference in treatment outcome according to histological type, but in stages IIA, IIB, and IIIC1 (FIGO 2018), the treatment outcome of nonsquamous cell carcinoma was significantly worse than that of squamous cell carcinoma. Considering post-treatment health care, it is important to consider ovarian preservation in young patients with cervical cancer, up to stage IIA (FIGO 2018) for squamous cell carcinoma and stage IB1 (FIGO 2018) for nonsquamous cell carcinoma, after careful evaluation of clinicopathological factors before surgery.
Discussion:
Locally advanced adenocarcinoma of the cervix is a rare and refractory cancer that has been shown to have low radiosensitivity, and its treatment outcome is still unsatisfactory. A new therapeutic strategy involving multidisciplinary treatment in combination with perioperative chemotherapy at a facility that can provide highly curative surgical treatment is desired.
Conclusion:
Minimally invasive surgery is being introduced for the treatment of early-stage cervical cancer. However, the number of eligible cases should be expanded in a phased manner, based on an objective evaluation of surgical outcomes at the facilities. Omics analysis may be useful to develop a new treatment for human papillomavirus nonrelated cervical cancer, represented by gastric mucinous carcinoma.
