Purpose: This study reported clinical results of patients with locally advanced cervical cancer who treated with radiotherapy and image-guided adapted brachytherapy and combinations of cytotoxic drugs.
Material and Methods: This study included 190 patients with cervical cancer IIb, IIIb, IVb (metastases in para-aortic lymph nodes) during 2011-2015 treated with external-beam radiotherapy or chemoradiotherapy, total dose for D95 50Gy for 25 fractions following Image-guided brachytherapy HDR with prescribing dose for CTV-HR D90 7.5 Gy weekly 4 fractions. Total dose CTV-HR D90 40 Gy (EQD2). Total dose for HR-CTV D90 was 95.0 ± 0.67 Gy (EQD2). Presented group A (n = 72) - radiation therapy, B (n = 40) - chemoradiation therapy with cisplatin C (n = 39) - chemoradiation therapy with a combination of irinotecan + cisplatin, 2 courses of adjuvant chemotherapy D (n = 39) - chemoradiation therapy with a combination of paclitaxel + cisplatin, 2 courses of adjuvant chemotherapy. Clinical outcomes including local control (LC), cancer-specific survival (CSS), overall survival (OS), and toxicity were analyzed.
Results: Three-year OS and CSS in groups A were: 88.4% ± 4.5% and 64.4% ± 7.3%; B - 77.7% ± 7.6% and 77.5% ± 7.1%; C - 69.8% ± 9.6% and 66.3% ± 8.9%; D - 81.3% ± 6.4% and 62.1% ± 8.0%, respectively (p> 0.05). The use of chemoradiotherapy in the groups did not increase the 3-year OS in cervical cancer stage IIIb: in group A - 84.0% ± 7.5%, B - 76.2% ± 9.4; C - 77.2% ± 9.1% and D - 84.9% ± 7.0% (p> 0.05). But CSS was higher on the 1st year of observation in group C - 96.3% ± 3.6% compared with group A - 74.2% ± 7.5% (p = 0.049). With a 3-year observation - 75.7% ± 9.6% and 59.0% ± 11.4%, respectively (p = 0.31). Combined chemoradiation therapy in patients with cervical cancer increases the time to progression: from 9.5 months (in groups A and B) up to 19.4 months and 16.4 months (in groups C and D), respectively (p = 0.05). A decrease in the number of local relapses during 3 years was obtained in groups B and D compared with group A (100% versus 90.3%, p = 0.05). Local control within 3 years among 190 patients was 94.7% ± 1.6%. Gastrointestinal early toxicity was noted higher in group C compared to A, B, D (rectites G2-3 - 25.7% versus 5.6%, 5.0% and 2.6%, respectively, p = 0.05). Late cystitis G2-3 is higher in groups B, C, D compared with group A (15.4% versus 4.2%, p = 0.07).
Conclusion: The study showed high efficiency of treatment of patients with cervical cancer due to the introduction of modern technologies in radiotherapy, as well as chemoradiotherapy programs with acceptable toxicity.
