RANDOMIZED STUDY COMPARING CHEMOTHERAPY PLUS RADIOTHERAPY VERSUS RADIOTHERAPY ALONE IN FIGO STAGE-IIB-III CERVICAL-CARCINOMA

Between January 1989 and December 1991, 64 patients with advanced cervical carcinoma FIGO stage IIb-III wert randomized to receive radiotherapy (RT) alone or the sequential combination of chemotherapy (CT) and RT. RT consisted of external RT (40 Gy fractionated over 4 weeks) + brachytherapy (40 Gy to point A) + an additional boost to the parameters (15-20 Gy) in arm RT; CT consisted of cisplatin 60 mg/m2 i.v. day 1 q 15 days administered for 2 cycles before the start of RT and for 4 cycles after the end of radiation treatment in CT + RT arm. Among the 58 evaluable patients objective response rate was as follows: in RT arm, CR in 40.7% of patients, PR in 40.7%, and SD in 18.6%; in CT + RT arm, CR in 42% of patients, PR in 35.5%, and SD in 22.5%. The median duration of response was 12 months (range: 3-38 + months). At a median follow-up of 36 months survival (S) and progression-free survival (PFS) were 83% and 72.4% in RT arm, 72% and 59.3% in CT + RT arm, respectively. No significant difference was observed between the 2 treatment arms, neither in terms of objective response nor in terms of S and PFS. Both treatments were generally well tolerated. In our experience the addition of chemotherapy to standard radiotherapy does not enhance morbidity and does not interfere with the correct delivery of the planned treatment. However, results of this combined modality regimen remain unsatisfactory, since no improvement in pelvic control and survival of patients with advanced cervical carcinoma was observed.
