title: Superficially invasive carcinoma of the vagina following treatment for cervical cancer: a report of six cases.
abstract: Six patients with superficially invasive squamous carcinoma of the vagina are described. All patients meet recently proposed criteria for the diagnosis of microinvasive vaginal carcinoma. The depth of invasion measured from the surface was less than 2.5 mm. There was no lymph-vascular space involvement. The invasive foci arose within a field of carcinoma in situ. Five of these six patients had previously been treated for invasive cervical cancer with pelvic radiation from 82 to 246 months before the diagnosis of vaginal carcinoma. All but one patient had the carcinoma confined to the upper one-third of the vagina. All patients were treated with a single vaginal radium application following vaginectomy. One of these six patients expired from recurrent vaginal cancer 35 months following diagnosis. During the same 17-year period, 17 other cases of Stage I epidermoid cancer of the vagina were treated which did not meet the above criteria for microinvasion. There were no statistically significant differences between these two groups with regard to age at diagnosis, history of cervical cancer, hysterectomy, or pelvic radiation or in survival. Additional experience with early vaginal carcinoma is needed before microinvasive carcinoma of the vagina should be accepted as a distinct clinical entity.
