[Uterine papillary serous carcinoma--one kind of special type of uterine endometrial carcinoma].

OBJECTIVE

To study the clinico-pathologic features of uterine papillary serous carcinoma and point out the complete difference between the two kinds of endometrial carcinoma.

METHODS

One hundred and ten cases of endometrial carcinoma who received treatment in the our hospital from May 1, 1982 to April 30, 1994 were analyzed retrospectively.

RESULTS

Of them, 10 cases (9.1%) of uterine papillary serous carcinoma (UPSC) were found. The age in average was 67.2 years old, which is nearly 10 years older than those with ordinary endometrial cancer (P < 0.01). The occurrence of UPSC was revealed no relationship with the relative factors of occurrence of endometrial carcinoma. The study shows that tumor has very marked tendency of lymph node metastasis, much worse grade, much deeper myometrial invasion and much earlier extrauterine disease.

CONCLUSIONS

UPSC is a special pathologic type of endometrial carcinoma with completely different clinico-pathologic behavior. The surgical staging is necessary for the patients with UPSC to get comprehensive stage because the clinical stage is usually not correct enough.
