Resumen
Introduction. For nearly the past two decades, cytokines (CKs) have been the only systemic treatment option available for advanced renal cell carcinoma (RCC). In recent years, tyrosine kinase inhibitors (TKIs) have demonstrated clinical activty on this tumour. Our purpose is to describe one centre´s experience with the use of CKs and TKIs in the treatment of patients with advanced RCC.
Materials and methods. This study was designed as a retrospective chart review of RCC patients who were treated with CKs and/or TKIs in our depoartment between July 1996 and June 2008. Efficacy and toxicity were assessed using World health Organization (WHO) criteria. The Kaplan-Meier method was used to estimate progression-free (PFS) and overall (OS) survival.
Results. Ninety-four patients were classified into three groups depending on the modality of treatment administered: 46 were treated with CKs alone and/or chemotherapy (27 with immunotherapy, one with chemotherapy and 18 with both), 28 with TKIs alone (25 with sunitinib and 13 with sorafenib) and 20 with TKIs in second-line treatment following failure with CKs (17 with sunitinib, 8 with sorafenib, 4 with bevacizumab and 1 with lapanitib). The median age was 60 years in the CK group and 65 and 62, respectively, in TKI in first and second-line treatment groups. 85% of patients treated with CKs and 75% in the TKI group in first-line treatment and 80% in second-line treatment were men. Overall, 89% of patients had favourable risk, and 11% had intermediate risk. All patients were considered evaluable for toxicity. The main grade 3-4 (%) toxicity was asthenia for both groups, (10 in TKIs and 15 in CKs). Other grade 1-2 toxicities were mucositis (39), bleeding (8), hypertension (19(, skin toxicity (33) and hypothyroidism (12.5) associated with TKIs; and anaemia (33), cough (29), asthemia (39) and emesis (14) associated with CKs. The objective response rate among 80 patients evaluable for activity was 10.6% with CKs and 46.5% and 35%, respectively, with TKIs in first- and second-line treatments. Disease stabilisation with CKs was recorded at 59% of patients and with TKIs 25% and 50% in first- and second-line treatment groups, respectively. The median progression-free survival (PFS) with CKs was 122 days [95% confidence interval (CI) 82-162] and with TKIs 201 days (65-337) in the first- and 346 days (256-436) in second-line treatment groups. The median overall survival (OS) was 229 days (142-316) and 2,074 days (1,152-2,996) for patients treated with CKs and TKIs.
Conclusions. Our results are in line with the activity and survival rates previously reported in the literature regarding the use of TKIs for patients with advanced RCC in first- and second line treatment, which has demonstrated an acceptable toxicity level.
