Carcinoma in situ of the uterine cervix. A review of some present clinical problems.
The vaginal smear reveals a spectrum of borderline lesions of the uterine cervix. This spectrum is the source of new clinical problems involving both the recognition and treatment of these various entities. A review of the literature of the past decade indicates that vaginal smears should be obtained regularly every year or two in all women beginning at the onset of sexual activity, but the initial smear may be falsely negative in 10 to 30 percent of cases. When patients have abnormal smears, the precise diagnosis can be established more accurately by cold-knife conization than by multiple punch biopsy. While hysterectomy has been considered "definitive treatment," late recurrence in the vagina occurs in 1.24 percent of patients so treated. A compilation of 1,100 patients with carcinoma in situ of the cervix treated by conization and follow-up smear reveals that in over 90 percent the disease was controlled by the cone alone, and the remainder by repeat cone or hysterectomy. Precise definition is required in treatment decisions concerning micro-invasive lesions, but these may be well treated by non-radical measures. In almost 500 patients so treated, no death occurred from therapy or tumor metastasis.When carcinoma in situ is found during pregnancy, a coexisting invasive carcinoma must be excluded by appropriate conization or punch biopsy and definitive therapy completed after vaginal delivery.
