Gynecologic Oncology

The Gynecologic Oncology service provides comprehensive cancer care for women with gynecologic cancers. A gynecologic oncologist specializes in the diagnosis and treatment of women with cancer of the reproductive organs.  Specifically, gynecologic oncologists treat cancer of the ovary, endometrium (uterus), cervix, vagina, vulva, and trophoblastic disease.

Dr. John Tatman and Dr. Daniel Kato are board-certified gynecologic oncologists with decades of experience who trained at institutions with international reputations for their quality. Woman with cancer of reproductive organs are referred to one of them for further evaluation and consideration of treatment options including surgery.  Their approach to therapy combines the most recent advances with a caring attitude in order to achieve the best results while minimizing the risk of problems.  They have chosen to practice in this setting so they can concentrate on providing high-quality care for cancer patients. Both stay up-to-date with the latest innovations, like laparoscopic and fertility-sparing procedures.  They see patients by referral only and their offices are located in the Women’s Clinic.

Debulking surgery is performed for woman with advanced ovarian cancer to remove as much of the tumor as possible. Patients who have had successful debulking surgery have a better outcome than those left with larger tumors after surgery.  After the surgery, patients are referred to the Department of Medical Oncology for considering chemotherapy including intraperitoneal chemotherapy.

Patients with uterine cancer (endometrial cancer) or cervical cancer may undergo hysterectomy (removal of the uterus) and removal of surrounding lymph nodes.  Some patients may be candidates for laparoscopic or robotic procedures.  Patients with uterine or cervical cancers may also be referred to the Department of Radiation Oncology for consideration of radiation therapy.
