RESUMO
OBJECTIVE: Therapies involving a radical operation and radiation treatment for cervical carcinoma in stages I and II are not sufficiently effective in patient subgroups with high risk for recurrence. In recent publications, patients with high risk cervical cancer had with adjuvant simultaneous radio-chemotherapy a better disease free and overall survival but a higher toxicity compared with patients received an adjuvant radiotherapy alone. MATERIAL AND METHODS: 34 patients with at least 2 risk factors for recurrence of cervical cancer were treated with adjuvant chemotherapy after radical hysterectomy. The protocol consisted of 3 cycles of ifosfamide 1.6 g/m2 (d 1-3) and carboplatin (AUC 4, d1) every three weeks. For cell protection 21 patients received amifostine 740 mg/m2 d1-3; this was followed by standard radiation therapy (50.4 Gy percutaneous and high-dose-rate-after-loading for 21 patients, 2 x 5 Gy). The dose determination of the substances and their toxicity were investigated. RESULTS: Patient (p) data: Median age 43 years (range: 25-70); pT1b-2a: n = 22; pT2b: n = 12; pN1: n = 28; pN0: n = 6; G3: n = 10; adeno- and adenosquamous carcinoma: n = 9, G3: n = 10, R1-resection: n = 5. 70.6% of these high-risk patients were disease-free after a median observation time of 40 (18-62) months. Median number of cycles of chemotherapy: 2.8. There was no more dose escalation than carboplatin according to AUC 4 possible. Hematologic toxicity (CTC grading, % of 96 documented cycles): anemia-grade 3-4: 30; -grade 1-2: 10.4; leukopenia-grade 3-4: 13, -grade 1-2: 21.7; alopecia-grade 3: all p.; cerebral neurotoxicity-grade 3-4: 8.3, -grade 1-2; 17.7; diarrhea under radiotherapy-grade 3-4: 2 p., -grade 1-2: 6 p. CONCLUSION: This combined sequential adjuvant therapy was effective and had an acceptable level of toxicity. A phase III study comparing adjuvant sequential chemo-radiotherapy with and without Erythropoeitin to counteract the negative effects of anemia started in Germany in 1999 and had randomized now about 270 patients.
