RESUMEN
BACKGROUND: After several decades, cisplatin continues to be an essential drug for the treatment of several tumors, however, its potential nephrotoxicity is still a clinically relevant issue. Identification of predisposing factors for renal toxicity could be of value to warrant prophylactic measures. METHODS: We analyzed data from 198 patients with various tumor types, treated with cisplatin containing regimens in our regional cancer center in a two-years period. Assessed variables included age, gender, smoking status, alcohol consumption, tumor type, prior or concomitant anticancer treatment, cisplatin dose, time-interval between cycles, number of cycles, concomitant nephrotoxic drugs or radiotherapy and co-morbidities. We divided cisplatin nephrotoxicity in two categories: transient and permanent. Univariable and multivariable analyses were performed in order to define statistical associations. RESULTS: Cisplatin discontinuation rate was 27,7%, of which, 8.1% was due to renal toxicity. A total of 74 and 21 patients developed transient and permanent nephrotoxicity, respectively. At univariable analysis cirrhosis (p = 0.027), hypertension (p = 0.020), alcohol intake (p = 0.030) and number of cycles < 4 (p = 0.002) were significantly associated with transient renal toxicity, while at the multivariable analysis, a statistical significance was detected for cirrhosis (p = 0.009), hypertension (p = 0.009) and a total number of cycles < 4 (p = 0.003). Regarding permanent renal toxicity, a concomitant administration of NSAIDs was significant at univariable analysis (p = 0.002). CONCLUSIONS: Relevant risk factors for the development of transient nephrotoxicity were defined. Patients presenting these baseline characteristics may require more frequent post-cycle check-up visits and hydration treatment should be guaranteed as soon as a reduction of creatinine clearance is detected.

BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine and prednisone) escalated is the preferred upfront Hodgkin lymphoma (HL) treatment in a number of countries. Upon failure, high-dose chemotherapy with autologous stem cell support (HDT/ASCT) is performed, but its effectiveness has not been verified in this setting. We analyzed all Swiss cases of chemosensitive HL autografted after failure of BEACOPP escalated (n = 22) and compared outcomes with 22 cases of HDT/ASCT following frontline ABVD (doxorubicin, bleomycin, vinblastine and dacarbazine) failure. Five-year progression-free survival (PFS) was 76% for ABVD and 42% for BEACOPP escalated (p = 0.029). Two- and 5-year overall survival (OS) was 90% and 71% for ABVD and 72% and 65% for BEACOPP escalated, respectively (p = not significant). Three patients in the ABVD and four in the BEACOPP escalated groups underwent allotransplant for relapse after HDT/ASCT. Grade 3-4 toxicities were comparable in both groups. Three cases of therapy-related myelodysplastic syndrome/acute myeloid leukemia (t-MDS/t-AML) were recorded in the BEACOPP escalated group. The acceptable PFS and OS of chemosensitive patients with HL autografted after failure of upfront BEACOPP escalated seem to justify this approach.
