Gynecological malignant tumors can develop in the vulva, vagina, uterus, fallopian tubes, or ovaries in the female reproductive tract. The cervix, uterine body, and ovaries are particularly common sites for malignant tumors. Surgery, radiation, and drug therapy are the main treatment modalities for gynecological cancers, with surgery being the most important of them.
We started laparoscopic surgery for uterine endometrial cancer as an advanced medical treatment in 2011 and contributed to its insurance coverage. We were able to reproduce our laparoscopic surgery more easily using the da Vinci Xi system for robotic surgery. We have now switched from laparoscopic surgery for endometrial cancer to robotic surgery and have been able to perform them safely and reliably.
In the case of cervical cancer, the results of the Laparoscopic Approach to Cervical Cancer (LACC) trial, which compared the prognosis of two groups of radical hysterectomy for early-stage cervical cancer: conventional open surgery and laparoscopic/robotic (minimally invasive) surgery, showed that minimally invasive surgery resulted in more pelvic recurrences and had a worse prognosis compared with open surgery. The trend toward minimally invasive surgery for cervical cancer has stagnated worldwide.
Ovarian cancer has few symptoms in the early stages and is often found at stage III or IV, when the cancer has spread throughout the abdominal cavity. As residual tumor after surgery correlates with prognosis in ovarian cancer, debulking surgery should be performed to achieve complete resection. Therefore, peritoneal or bowel resection is often required to remove disseminated or metastatic tumors. We also performed prophylactic salpingo-oophorectomy to prevent ovarian and fallopian tube cancers in patients with BRCA1/2 gene variants.
The uterus and ovaries are organs necessary for pregnancy and childbirth, and cancer of the uterus or ovaries in women of childbearing age may result in infertility. Surgery and adjuvant treatment may affect marriage, childbirth, and sexual life; therefore, it is important to ensure the cure of cancer and to provide patients with treatment methods that allow them to live their lives as women.
