Résumé

Objectives: The aim of the study is to evaluate clinical features of patients with low-risk stage I endometrium cancer, who received adjuvant therapy or followed with observation only and to analyse the effects of known prognostic factors in this group of patients. Materials and Methods: A total of 246 patients (median age: 53, range: 31-77) with low-risk stage I endometrial cancer, who were just followed postoperatively (156 patients) or received adjuvant radiotherapy (90 patients) between 1996 and 2007 were reviewed retrospectively. Results: Local recurrence was detected in four patients, distant metastasis occurred in seven patients, and two patients had both local recurrence and distant metastasis. The 83.3% of recurrences were on the vaginal stump. Five- and ten-year local control (LC) and overall survival (OS) rates are 97.6%, 97.6% and 96.4%, 93.5% in the observation and adjuvant therapy groups, respectively, whereas distant control rates are 96.7% and 96.3%. In multivariate analysis, only age and lymphovascular invasion (LVI) were found to affect OS and disease-free survival (DFS). Conclusions: LC and OS rates are high in the low-risk group of patients; however, current adjuvant therapies did not improve the outcomes. Age over 60 years and the presence of LVI have negative effects on outcomes in this group of patients.

Résumé

Background : After orchiectomy in stage I seminoma the standard is adjuvant radiation therapy. We analyzed the patients retrospectively to evaluate the contributions of the treatment volume and dosage to treatment outcomes. Materials and Methods : Between January 1999 and December 2005, 91 stage I seminoma patients with a median age 36 (range;22-62) applied to our center, who were treated using anterior-posterior parallel opposed fields with linear accelerator or Co60 after orchiectomy. Twenty-five (27.5%) patients received irradiation to the paraaortic and ipsilateral pelvic nodes, and 66 (62.5%) patients only received to paraaortic nodes. Results : With a follow up time of median 57 months (range; 27-104), paraaortic nodes treated group had 4 relapses (6%) - 3 of them pelvic, one of them both pelvic and paraaortic. Both paraaortic and ipsilateral nodes irradiated patients had only one relapse (4%) (P = 0.726). While the 5 year overall survival (OS) is 98.8%, it is 100% in the dog-leg group and 98.4% in the paraaortic group (P = 0.548). Univariate analyses of OS and Disease Free Survival (DFS) showed that there is no statistically significant difference related to factors as age, histologic subgroup, tumor size, rete testis involvement, radiotherapy (RT) fields, dose ranges and the therapy device. Conclusion : Adjuvant RT approach is the preferred for non-compliant low risk patients as well as intermediate and high risk patient in stage I seminoma. 20 Gy/ 10 fractions/ 2 weeks RT is the adequate treatment.
