  1. Blood transfusion as a risk factor for non-Hodgkin lymphoma.

    Article - En anglais

    In a case control study of 280 out of 426 consecutive patients with a recent diagnosis of non-Hodgkin lymphoma (NHL) and 1827 control subjects, 53 (19%) and 230 (13%) respectively had received blood transfusions 1 year or more before the interview.

    Using an age-and sex-stratified analysis the odds ratio (OR) for transfusion was 1.74 (95% CI 1.24-2.44).

    ORs were also determined for transfusions received in the intervals 1-5,6.15,16-25 and =26 years before diagnosis.

    In the interval 6-15 years, the OR for transfusion was 2.83 (95% CI 1.60 4.99) whereas ORs for transfusions received in other intervals were lower and not significantly elevated.

    Histological diagnoses (Kiel classification) and results of staging procedures were known for 185 patients.

    For low-grade NHL of nodal B-cell chronic lymphocytic leukaemia (B-CLL) or immunocytoma type, the OR for transfusions was 4.15 (95% Cl 1.92-9.01).

    For low-grade nodal lymphomas of follicle centre cell type and high-grade nodal lymphomas, no relation to transfusions could be demonstrated.

    For high-grade extranodal lymphoma as sole manifestation, OR for transfusions was 3.27 (95%, CI 1.30 8.24).

    It is concluded that blood transfusion may be a risk factor for NHLs especially those of B-CLL or immunocytoma type and for high-grade extranodal lymphoma.
