Patterns of recurrence of carcinoma following radical hysterectomy.
One hundred eighty-six radical abdominal hysterectomies are reviewed. Twenty-two instances of clinically recurrent carcinoma following operation were encountered over a 18-year period. In review of these cases it is apparent that patients with adenocarcinoma or adenocystic carcinoma have an increased likelihood of positive lymph node metastases or lymphatic-vascular invasion at the time of surgery. If this occurs, there is an increased probability of recurrent disease. Poor differentiation of the tumor, bulky disease, deep infiltration of tumor, involvement of capillary-like spaces, and lymph node metastases all appear to represent poor prognostic indices in patients operated upon. Patients with adenocarcinoma generally have a longer disease-free interval before recurrence than patients with squamous carcinoma. Postoperative radiation therapy following radical surgery appears to increase significantly the disease-free interval until recurrence and influences the site of recurrent disease but has no demonstrable effect on ultimate survival.
