[Surgical treatment and prognostic analysis of 39 cases invasive vulvar cancer].
OBJECTIVE
To summarize the procedure of operations and evaluate the prognostic factors in the invasive vulvar cancer.


METHODS
Thirty nine cases with invasive vulvar cancer admitted in our hospital from 1979 to 1997 were retrospectively analyzed. Three kinds of operations were used: 5 by local excision, 13 by modified radical vulvectomy and 21 by radical vulvectomy. Statistical package for social sciences (SPSS) was used to compare the different strategy of operation and analyze the prognostic factors.


RESULTS
Thirty three patients (84.6%) had squamous cell carcinoma and 26 of them (78.8%) were well differentiated and 2 poorly differentiated. Seven cases (17.9%) were in FIGO stage I; 17 (43.6%) in stage II; 13 (33.3%) in stage III, and 2(5.1%) in stage IV, 58.3% of tumor in stage I and II were lateral while 73.3% of tumor in stage III and IV were median type. Hospitalization time for local excision, modified radical vulvectomy and radical vulvectomy (separated and en-bloc incision) were 9.1, 20.6, 41.2 and 62.2 days (P < 0.01) and the incision infection rate were 0%, 30.8%, 66.7% and 88.9% (P < 0.01) respectively. Median survival time for stage I, II, II and IV were 132.0, 121.5, 67.5 and 21.5 months (P = 0.01) and the 5-year survival rates of them were 85.7%, 70.6%, 46.2% and 0.0% (P < 0.05) respectively. Median survival time for patients with or without lymph nodes involvement were 66.0 and 121.5 months (P < 0.01) and the 5-year survival rates were 30.0% and 71.5% (P < 0.05) respectively. Median survival time for well or poor differentiation were 97.0 and 64.0 months (P > 0.05) and the 5-year survival rates were 62.0% and 43.0% (P > 0.05) respectively.


CONCLUSIONS
The important prognostic factors for invasive vulvar cancer were sites(lateral/median), stage, differentiation and lymph nodes involvement. Individualized treatment should be considered.
