Purpose.: To analyze the results of treatment and identify prognostic factors for primary squamous cell carcinoma (SCCA) of the vagina managed with radiotherapy at a single institution. Materials and methods.: Seventy-eight patients were analyzed in this retrospective series. Mean characteristics: follow-up 89 months; age 65 years (range 33-99); tumor size 3.8 cm (0.3-10); treatment hemoglobin 12.4 g/dl (range 8.7-14.4); and tumor dose 72 Gy (range 6-127). In addition, 49% of our cohort had a prior hysterectomy. The FIGO stage distribution: I (42%); II (29%); III (17%); and IVA/B (11%). Sixty-two percent of patients were treated with a combination of external beam radiation (EBRT) and brachytherapy, 22% with EBRT alone and 13% with brachytherapy alone. Results.: Kaplan-Meier (KM) 5-year pelvic control, distant metastasis free survival and disease specific survival probabilities: stage I, 83%, 100%, and 92%; stage II, 76%, 95%, and 68%; stage III, 62%, 65%, and 44%; and stage IV, 30%, 18%, and 13%. On multivariate analysis: stage; treatment hemoglobin; and prior hysterectomy were prognostic for DSS (p < 0.05). The KM 5-year grade 3/4 (G3/4) complication free estimate of our cohort was 84%. G3/4 complications: tumor size and tumor dose were independently predictive (p < 0.05). Conclusions.: Radiotherapy as a single modality for early stage primary vaginal SCCA produces good results. Advanced stage disease necessitates a combined modality approach and/or new methods. Treatment Hg levels appear to be clinically significant and studies on correction of anemia during treatment are warranted.
