Surgical Treatment of Vaginal Cancer: Follow-up
Updated: Dec 10, 2007
Outcome and Prognosis
The outcome of exenteration has improved significantly over time in terms of operative mortality and 5-year survival rates. In 1965, Brunschwig reported an operative mortality rate of 16% and a 5-year survival rate of 20%36 ; in 1989, Morley et al reported an operative mortality rate of 2% and a 5-year survival rate of 61%37 . In general, the operative mortality rate is less than 5%, and the 5-year survival rate is about 40%. Improved hemodynamic monitoring, nutritional support, and advances in surgical techniques and instruments contribute to the decrease in intraoperative mortality and morbidity. Anterior exenteration has a better survival rate than total exenteration, 30-60% versus 20-46%.
Clinical factors that affect survival
- Length of time from initial radiation therapy to exenteration: Less than 1 year is a poor prognostic sign.
- Size of the central mass (>3 cm)
- Preoperative sidewall fixation as determined by clinical examination
Pathological factors that affect survival
- Tumor extension: In 1989, Anthopoulos and colleagues reported that the most important risk factor for reduced survival was the extension of the tumor laterally into the surgical margins.38
- Positive nodes: In 1989, Morley et al reported a 5-year survival rate of 70% for negative nodes versus 0% for positive nodes.37
- Spread of tumor to adjacent organs
Age can affect the operative mortality rate but not the 5-year survival rate. In 1992, Matthews et al reported that patients older than 65 years had the same 5-year survival rate of 45% as patients younger than 65 years.22 The operative mortality rate of the older group was 11% versus 8.5% in the younger group.
Anthopoulos et al found that 84% of the patients were rehospitalized for complications that occurred more than 30 days after surgery; complications usually involved the gastrointestinal or urinary tract.38 Surgical intervention was required for 58% of patients with complications occurring 1 year after surgery, while 74% required surgery within the first year.
Organ reconstruction, including low rectal anastomosis, continent vesicostomy, and vaginal reconstruction, has significantly improved quality of life after pelvic exenteration. In 1997, Hawighorst-Knapstein and colleagues reported that patients with no ostomies have a much better quality of life and body image than patients with 2 ostomies.39 They also reported that women with vaginal reconstruction reported fewer problems related to quality of life and significantly fewer sexual problems. As compared to healthy women with sexual dysfunction, in 1983 Andersen et al reported that women with vaginal reconstruction have significant reductions in sexual activity and arousal in addition to greater sexual anxiety.31
Regarding outcome and prognosis, the main concern of the patient and physician is the possibility of recurrence of the primary disease.
Future and Controversies
Although primary vaginal carcinoma is a rare gynecologic malignancy, its impact on women's health should not be underestimated, especially when considering the demographic increase in elderly women. As more women survive past the age of 60 years, physicians need to consider the likelihood that more women will present with vaginal cancer.
Although screening is not indicated based on the low incidence of vaginal carcinoma, screening should be reconsidered in the near future because of evidence that links HPV infection to the pathogenesis of vaginal cancer.
In June 2006, the Advisory Commitee on Immunization Practices (ACIP) voted to recommend the first vaccine developed to prevent cervical cancer and other diseases caused by HPV type 6, 11, 16, and 18. The vaccine is almost 100% effective in preventing precancerous lesions of the cervix, vulva and vagina, and genital warts caused by the HPV 6, 11, 16, and 18. The FDA has approved Gardasil for girls and women ages 9-26.
Because the 5-year survival rate of treated early stage vaginal cancer is significantly higher than advanced stages, early detection is key to improving outcome. To improve outcome of primary vaginal carcinoma, oncology centers should receive more cases per month in order to plan randomized prospective studies. This would be possible if a few oncology centers are selected for referral of all newly diagnosed cases. This would increase the experience of any of these centers in treating primary vaginal carcinoma.
