RESUMEN

BACKGROUND: Most Hodgkin lymphomas (HL) can be cured with current strategies. However, one-third of the cases do not respond or relapse and need salvage regimens. We report the results of a retrospective study using the gemcitabine and oxaliplatinum (GemOx) regimen. METHODS: Patients who relapsed or failed to achieve complete response were eligible and received GemOx salvage therapy. To avoid selection bias and thus to overcome the retrospective nature of the study, all treated patients were included from the pharmacy database. RESULTS: Between 2003-2013, 24 HL patients - relapsing (number [n]=12) or refractory (n=12) - were included, receiving a total of 26 induction treatments with GemOx. Mean previous regimens were 2.38 (42% relapsing after autologous transplantation). Median follow-up was 37 months, and 71% responded (38% of patients achieved complete response). The factors related to better progression-free survival were: B symptoms; response to GemOx; and consolidation with stem cell transplantation. Grades 1 and 2 neurological toxicity was present in 17% of patients. Hematological toxicity was common, with grades 3 and 4 neutropenia (25%) and thrombocytopenia (34%) observed. Progression-free survival was better in patients consolidated with stem cell transplantation. The peripheral blood stem cell collection after GemOx was successful for all candidates. CONCLUSION: 1) The GemOx regimen is effective in relapsed or refractory HL with manageable toxicity. 2) No mobilization failures were observed. 3) Consolidation after response is needed. 4) Its efficacy and favorable toxicity profile might make multiple administrations possible in several recurrences in HL.

RESUMEN

Imatinib mesylate (IM) is the treatment of choice in patients with newly diagnosed chronic myeloid leukemia (CML), irrespectively of their age. Nevertheless, information regarding tolerability and responses in advanced-age patients, a subgroup in which co-morbidities and other factors may influence outcome, is scarce, since they were excluded from most clinical trials. In this observational study (ELDERGLI), information regarding demographics, concomitant medication, physical examination, performance status, hemogram, biochemistry, hematologic, cytogenetic and molecular responses, time to progression, adverse events (AE) and severe adverse events (SAE) were prospectively recorded in a series of 36 elderly patients with CML, with a median age of 76.6 years. Most patients had cardiovascular co-morbidities, especially hypertension. Regarding IM toxicity, around one third of patients required treatment interruptions because of adverse events, especially hematologic toxicity (66% of cases that needed dose interruptions). When analyzing non hematologic adverse events, the most frequent ones were superficial edemas and GI symptoms. Of note, 9 of patients experienced an infection episode during the follow-up, and 4 were diagnosed during the study period of another type of cancer. Finally, cardiovascular events were reported in 7 patients, most of them with prior cardiovascular risk factors. Regarding responses, after 12 months of imatinib therapy, the rate of complete hematologic response (CHR), complete cytogenetic response (CCyR) and major molecular response (MMolR) were 89%, 72% and 55% respectively. In summary, IM display, in advanced-age patients with chronic phase CML, an efficacy and safety profile comparable to younger patients.
