Long-term results of the treatment of Hodgkin's lymphoma in a resource-constrained setting: Real-world data from a single center.

BACKGROUND: The outcomes of Hodgkin´s lymphoma (HL) in México have not been widely reported. Simplified and affordable treatments have been adopted in middle-income countries. AIM: The aim was to evaluate long-used therapies for HL in México in a long-term basis. METHODS: In a 34-year time period, 88 patients with HL were treated at a single institution in México. Patients were treated with adriamycin bleomycin vinblastine and dacarbazine (ABVD) or mechlorethamine, vincristine, procarbazine, and prednisone (MOPP). Relapsed or refractory patients were given ifosfamide, carboplatin, and etoposide (ICE) followed by autologous or allogeneic stem cell transplants. RESULTS: Thirty-seven women and 51 men were included; the median age was 29 years. Patients were followed for a mean of 128 mo. The 310-mo overall survival (OS) was 83% for patients treated with MOPP and 88% for those treated with ABVD. The OS of patients who received autologous stem cell transplantation was 76% (330 mo) vs 93% (402 mo) in those who did not. CONCLUSION: HL may be less aggressive in Mexican population than in Caucasians. Combined chemotherapy renders acceptable results, regardless of clinical stage.

Up to half of patients diagnosed with chronic lymphocytic leukemia in México may not require treatment.

Introduction: Although therapeutic choices for patients with chronic lymphocytic leukemia (CLL) were once limited, treatment of this disease has vastly improved in the last decades.Patients and methods: Consecutive CLL patients diagnosed in a single institution were analyzed. Treatment was withheld in persons with CLL Rai stage 0 or 1, until progression and in persons with stages 2-4, with a negative expression of ZAP-70 until progression. Between 1983 and 1991, patients were give chlorambucil and prednisone (CP); after 1991 fludarabine and cyclophosphamide (FC) and after 1998, rituximab and FC (FCR).Results: 98 patients with CLL were identified; 49 were followed for >3 months. 21 persons (43%) did not require treatment nor progressed; 14 received CP, 6 FC, 7 FCR and one rituximab. Median overall survival (OS) has not been reached, being above 247 months; median OS for patients given CP was 115 months, for FC above 132 months and for FCR above 136 months (p > 0.5).Conclusion: CLL seems to be less aggressive in Mexican mestizos than in Caucasians; 43% of patients do not need treatment at all.
