Para-aortic and Pelvic Radiotherapy, an Effective and Safe Treatment in Advanced-stage Uterine Cancer.

AIM: The present, was a feasibility study of extended-field (EF) external-beam radiotherapy (EBRT) and vaginal brachytherapy (VBT) given sequentially following complete staging and adjuvant chemotherapy for patients with advanced-stage endometrial carcinoma (EC).

PATIENTS AND

METHODS

A cohort study was carried out in 38 patients with stage IIIC and IVB EC treated by surgery, six cycles of paclitaxel-carboplatin chemotherapy followed by EF EBRT and VBT.

RESULTS

A total of 60% of the patients had non-endometrioid histology, 45% had both pelvic and para-aortic lymph node metastases. Two patients experienced recurrence in the previously irradiated field. Five-year overall and progression-free survival were 77% and 72.5%, respectively. Grade 1 diarrhea and grade 1 cystitis were the most common acute and delayed side-effects.

CONCLUSION

EF EBRT and VBT following complete staging and adjuvant chemotherapy is a safe and effective treatment for patients with advanced-stage EC. Compared to historical data, our study suggests an improved progression-free and overall survival with acceptable acute and delayed side-effects.
