Management of stage IA carcinoma of the cervix.

One hundred fourteen patients with Stage IA carcinoma of the cervix were retrospectively reviewed in regard to depth of invasion, capillary-like space involvement, stromal reaction, status of conization margins, and the incidence of lymph node metastasis. Type of treatment, recurrences, and deaths were also evaluated. Patients with less than 3 mm invasion can be treated conservatively, including conization, if fertility is desired. No lymph node metastasis or recurrence appeared in this group of patients irrespective of type of treatment. Patients with 3 to 5 mm invasion do appear to be at higher risk for recurrence, but conservative therapy may be used in individualized situations. Size of conization and status of surgical margins appear to be important determining factors in regard to conservative therapy. Data in the literature, as well as our experience, although limited, suggest that the status of capillary-like space involvement does not influence lymph node metastasis or recurrence. Invasion of 5 mm or more in depth should be treated as a Stage IB occult lesion.
