title: Chronic lymphocytic leukemia in India--a clinico-hematological profile.
abstract: Chronic lymphocytic leukemia (CLL) is the most common form of leukemia in elderly people. The clinico-hematological profile and treatment outcome of patients with CLL were assessed using retrospective case record analysis over 11 years. There were 95 (75 males: 20 females) patients with a median age of 61 years. Thirty patients were aged 55 years or less (young CLL patients) and 65 were more than 55 years of age (elder CLL patients). Sixty percent patients had non-specific complaints, such as weakness, cough and indigestion. Twenty-six (27%) patients had pallor and 24 (25%) had fever as initial presenting manifestation. Bleeding manifestations were seen in 7 patients. Seven patients were diagnosed incidentally. Lymphadenopathy, splenomegaly and hepatomegaly were seen in 52 (55%), 63 (66%) and 60 (63%) patients, respectively. The median white blood cell count and absolute lymphocyte counts were 70,600 and 51,490/mul, respectively. Three patients had autoimmune hemolytic anemia. Twenty-five patients (26%) had anemia with hemoglobin < 11 g/dl and thrombocytopenia with platelet count 100 x 10(3)/mm(3) was seen in 17 (18%). Interstitial nodular, mixed and diffuse bone marrow (BM) involvement was seen in 10.2, 67.3, 6.1 and 16.3% cases, respectively. Eighteen (60%) young patients and 35 (54%) older patients required treatment with chlorambucil. The mean time from initial diagnosis to treatment was 4.6 +/- 10.7 months. None of our patient attained complete response. Six patients obtained partial response. Median duration of chlorambucil was 7 months (1-86 months). Forty-six patients had stable disease. Three patients died. Median survival of study group was 4 years (8 months-13 years). In older CLL it was 4 years (8 months-11 years) and in young patients, survival duration was 5.5 years (1-13 years).
