Objective: To explore the practical value of surgical-pathological staging for endometrial carcinoma.
Methods: Ninety-six patients with endometrial carcinoma accepted primary surgical treatment from January 1995 to December 1999 were analyzed retrospectively in our hospital. The clinical and surgical pathologic staging of these patients were compared.
Results: The total differences between clinical and surgical-pathologic staging were 44 cases (45.8%), in stage I 24.0%, stage II 76.9%, in stage III 2 of 5 cases. The metastasis rate of pelvic lymph nodes was 10.3%, in stage I 1 of 16 cases, stage II 14.7%. Fourteen patients (14.6%) with extrauterine pelvic metastasis were found, of which 2 of 19 cases in stage I b, 23.1% in stage II. 9.4% with ovarian metastasis, in stage I a 9.7%, stage II 10.3%. 7.9% with positive peritoneal cytology, in stage I 4.0%, stage II 10.3%. 5.2% with omentum metastasis. 2.1% with appendix metastasis. Clinical stages, depth of myometrial invasions, pathological grades and histological types were related to the extent of pelvic and abdominal cavity by univariate analysis (P < 0.01, 0.05). The first three factors were significantly correlated to dissemination by multivariate (P < 0.05).
Conclusions: The surgical-pathological staging is more accurate than the clinical staging, especial in stage II clinical stage depth of myoinvasion, patho-histological grades were closely related to the dissemination in pelvic-abdominal cavity. The surgical-pathological staging is able to assess prognosis objectively and guide therapy for endometrial carcinoma.
