ABSTRACT
Background: The overall survival and relapse-free survival have
increased with current chemotherapy in patients with non-lymphoma
Hodgkin. A useful tool to evaluate projections is the International Prognostic
Index. Our aim was to evaluate the relation between the prognosis
established with the International Prognostic Index and the survival
obtained in two years by patients with diffuse large
B-cell lymphoma.
Methods: An observational, longitudinal, prospective study was carried
out. Patients included were those with diagnosis and treated along a
year, who, at some point in their evolution, required hospitalization. All
the patients received ciclofosfamide, doxorrubicine, vincristine and prednisone;
additionally, some of them received rituximab. The follow-up average
was 26 months. Survival was estimated with Kaplan-Meier curves.
Results: Forty-nine patients were included and classified according to
the International Prognostic Index risk. The survival was 90 % for patients
with International Prognostic Index low risk, 66.7 % for the patients with
intermediate-low risk, 80 % for patients with intermediate-high risk, and
81 % for patients with high risk. The survival for all risk groups was 77.6 %.
When we compared the survival of patients with the expected prognosis
through the International Prognostic Index, we obtained
p = 0.0000.
Conclusions: Two years after diagnosis, the survival of patients with
diffuse large
B-cell lymphoma in the study was better than the prognosis
estimated through the International Prognostic Index, and similar to that
reported in American studies.
