Clinical studies with adjunctive surgery and irradiation therapy in the treatment of carcinoma of the cervix.
The majority of patients with cancer of the cervix are treated adequately by irradiation alone, and surgery is not necessary. A role for operation developsin certain patients with Stage I-II cancer of the cervix, who are prone to develop central recurrence if treated by irradiation alone. In these patients the primary lesion is massive. The vasculature to the center of these bulky or barrel-shaped cancer is insufficient, and a population of the cancer cells, perhaps related to anoxia, is more resistant to irradiation. The postirradiation conservative hysterectomy was incorporated into the treatment plan for 212 selected patients and the number of local recurrences was reduced. Incomplete cure of the peripheral component of the disease is another mechanism of treatment failure. This may occur, even though the primary lesion is cured. Patients with cervical cancers greater than 5 cm diameter have a high incidence of node metastasis, regardless of clinical stage. In those patients with positive nodes, the standard portals for external irradiation were expanded to include nodes at higher levels. The site of metastases was established by pretreatment laparotomy and the irradiation portals were then extended to include the involved nodes. Survival rates were not improved, because recurrences were not prevented, and death from treatment complications were high.
