Infections in the immunocompromised host: a prospective multicenter survey in patients receiving chemotherapy for acute leukemia.

Patients receiving chemotherapy for acute leukemia were prospectively followed up to determine the frequency, nature and outcome, of episodes of infection during a 6 or 12 month period at each of the participating centres. A total of 605 cycles of chemotherapy were surveyed. Of these, 490 cycles were received by patients with acute lymphoblastic leukemia (ALL) and 115 by patients with acute non-lymphoblastic leukemia (ANLL).

Prognostic variables and survival in pediatric acute lymphoblastic leukemias: cancer institute experience.

This presentation is an analysis of front-end prognostic variables in achieving a complete response, a continuous complete remission, and disease-free survival in pediatric acute lymphoblastic leukemia at the Cancer Institute, Madras, India between 1983 and 1988. The clinical characteristics at presentation showed that virtually 100% of patients belong to the poor risk category, age < 3 years of > 6 years 72.2%, WBC > 10,000/mm3 59.

Immunophenotyping of acute lymphoblastic leukaemia in Madras, India.

At the Cancer Institute, Madras, India, we have performed immunophenotyping in 125 untreated cases of acute lymphoblastic leukaemia using a panel of 16 monoclonal antibodies and the avidin-biotin immunoperoxidase technique in a haematology autoanalyser (Technicon Hi system). Our results demonstrate a marked difference in the phenotypic pattern of ALL compared to Western countries, the predominant finding being a relative excess of T-ALL and a paucity of C-ALL cases. Age distribution of C-ALL reveals a peak at 2-6 years in paediatric ALL cases.

Antibiotics in febrile neutropenia: a randomized prospective comparison of two combinations.

Background: Problems of initial empirical antibiotic therapy in febrile neutropenia are further complicated by other factors such as cost and the pattern of infective organisms in a particular institution. We, therefore, conducted a randomized study comparing the efficacy of two sets of antibiotics which differed in their spectrum of action, availability and price.

Methods: Sixty episodes of febrile neutropenia in 40 patients who were not on any prophylactic antibiotics were randomized into one of two arms--cefotaxime and gentamicin or ciprofloxacin and gentamicin.
