BACKGROUND AND PURPOSE: To assess feasibility, safety and effectiveness of CT-based 3D conformal external beam radiotherapy (EBRT) plus concurrent cisplatin and MRI-based 3D conformal HDR-brachytherapy (HDR-BT) in the treatment of advanced cervical cancer. PATIENTS AND METHODS: A total of 48 patients with advanced cervical cancer, treated with CT-based EBRT plus simultaneous cisplatin chemotherapy (40mg/m(2) of body surface per week for 5 weeks) and MRI-based HDR-BT, were included for analysis. RESULTS: All patients completed radiotherapy as planned and 90% received at least four cycles chemotherapy. Frequencies of CTC grade 3 anaemia, grade 3-4 leucopenia and grade 3 thrombocytopenia were 4, 23 and 10%, respectively. Two patients developed deep vein thrombosis and one non-fatal pulmonary embolism. Grade 4 genitourinary late side effects (bladder) occurred in 2 patients. No grade 3-4 gastrointestinal side effects were observed. Complete response (CR) was obtained in 45 patients (94%). After a median follow-up of 33 months, 27 patients were disease free. Actuarial overall survival at 3 years was 61%, progression free survival 51% and continuous complete remission for true pelvis 85%. CONCLUSIONS: MRI-based 3D HDR-BT and 3D EBRT plus cisplatin appears to be safe and effective, although acute haematological toxicity is increased. Gastrointestinal morbidity is minimal when prospectively applying 3D dose volume constraints and MRI-based 3D dose volume adaptation.
