Hk. Poulsen et al., ADJUVANT RADIATION-THERAPY IS NOT NECESSARY IN THE MANAGEMENT OF ENDOMETRIAL CARCINOMA STAGE-I, LOW-RISK CASES, International journal of gynecological cancer, 6(1), 1996, pp. 38-43
In an attempt to create uniform nationwide guidelines for the manageme
nt of all stages of endometrial carcinoma, and to limit the use of adj
uvant radiation therapy in stage I disease to high-risk patients only,
a protocol was developed by the Danish Endometrial Cancer group (DEMC
A). From September 1986 through August 1988, 1214 women in Dennark wit
h newly diagnosed carcinoma of the endometrium have been treated accor
ding to this protocol. This figure represents all endometrial carcinom
as diagnosed in Denmark during this 2-year period. The primary treatme
nt was total abdominal hysterectomy and bilateral salpingo-oophorectom
y and no preoperative radiation therapy was delivered. Ln 1039 cases n
o macroscopic residual tumor and/or microscopic tumor tissue in the re
section margins was found following surgery. Based on surgery and hist
opathology, these patients were classified as: P-stage I low-risk (gra
de 1 & 2 and less than or equal to 50% myometrial invasion), P-stage I
high-risk (grade 1 & 2 and > 50% myometrial invasion, and grade 3), P
-stage II and P-stage III (Group 1). Distribution was as follows: P-I
low-risk 641 patients, P-I high-risk 235, P-II 105 and P-III (Group 1)
58 patients. No postoperative radiation therapy was given to P-I low-
risk cases. P-I high-risk, P-II, and P-III (Group 1) cases received ex
ternal radiation therapy. Recurrence rate at 68-92 months follow-up wa
s 45/641 (7%) in P-I low-risk, 36/235 (15%) in P-I high-risk, 30/105 (
29%) in P-II, and 27/58 (47%) in P-III (Group a) cases. Fifteen of 17
vaginal recurrences in P-I low-risk cases were salvaged (mean observat
ion time 61 months).
