BACKGROUND: Pelvic radiation therapy with concomitant chemotherapy (PCRT) is the standard treatment of stage IB2/II cervical carcinoma. The impact of concomitant chemotherapy on positive para-aortic nodes (PA+), however, remains unknown. The aim of this study was twofold: to evaluate the rate of histological PA+ after PCRT and to determine the survival of patients with PA+. METHODS: Patients fulfilling the following inclusion criteria were studied: (1) stage IB2/II cervical carcinoma, (2) histological subtype: squamous cell, adenocarcinoma or an adenosquamous tumor, (3) exclusion of patients with radiological PA+ (CT scan/MRI), (4) pelvic external radiation therapy of 45 Gy with concomitant chemotherapy (cisplatin 40 mg/m2/week) + utero-vaginal brachytherapy, and (5) completion surgery after the end of PCRT including at least a para-aortic lymphadenectomy. RESULTS: Seventy-three patients (16 stage IB2, 57 stage II) treated between 1998 and 2004 fulfilled all the inclusion criteria. PA+ after PCRT were observed in 13 patients (18%) with a median of five (range, 2-22) positive nodes. Overall and disease-free survival at 24 months in patients with PA+ was 40% and 17%. Only two patients with PA+ are currently alive and in remission. CONCLUSIONS: The rate of PA+ remains high after PCRT in patients treated for stage IB2/II cervical carcinoma. Furthermore, the survival rate of patients with PA+ is very low. These important results suggest that detection of PA + at the time of completion surgery (after PCRT) is not beneficial for improving survival.
