RESUMEN
BACKGROUND: Febrile neutropenia is a medical emergency and it requires immediate hospitalization for evaluation and administration of empiric broad-spectrum antibiotics. The present study was undertaken to analyze the infectious agents, choice of empiric antibiotics, and outcome in high-risk febrile neutropenia in the solid organ malignancies. MATERIALS AND METHODS: In this study, 92 high risk febrile neutropenic episodes were analyzed in 72 patients with solid organ malignancies. We used cefoperazone-sulbactum as an initial empiric antibiotic. Piperacillin/tazobactum or carbapenems were added to the patients who did not respond to initial antibiotic. RESULTS: Among the 92 episodes treated, most patients received first-line chemotherapy for locally advanced disease. Microbes were isolated in 25% of febrile neutropenic episodes. Gram-negative organism (61.70%) constituted the most common isolates. The most common microbes identified were E. coli and Staphylococcus aureus in blood, Klebsiella pneumonia in sputum and E. coli in urine culture. Patients who had been treated with cefoperazone-sulbactum improved clinically in 70.6% of febrile neutropenic episodes. Second- line antibiotics (piperacillin-tazobactum with amikacin) were required in 24% episodes, while another 5.4% episodes required third-line antibiotics (carbapenems). In this study, mortality was seen in 12% of febrile neutropenic episodes. Staphylococcus aureus was 100% sensitive to linezolid, teicoplanin, and vancomycin, whereas Gram-negative organisms were 100% sensitive to imepenem and meropenem. CONCLUSION: Cephaperazone-sulbactum is a reasonable initial choice for empirical therapy in high risk febrile neutropenic patients in solid organ malignancies.

BACKGROUND: In patients with small-volume disseminated disease of germ cell tumors, cure can be achieved with four cycles of bleomycin, etoposide, and cisplatin (BEP). However, around 20% of these cases are not curable. Strategies to improve cure rates have shown that none of the currently available modalities were superior to the others. Among the most used ones, BEP and VIP (etoposide, cisplatin, and ifosfamide) have been the most studied. However, there are no reports comparing the two, except for a few in abstract forms from southern India. Therefore, we did a treatment outcome and cost-effectiveness analysis of two chemotherapeutic regimens (BEP vs VIP) that are used in poor-prognosis metastatic germ cell tumors. MATERIALS AND METHODS: All male patients with germ cell tumors, diagnosed as having poor risk by IGCCCG, between January 2002 and December 2004 were included in the study. Clinical, laboratory, and other data were recorded. The patients were stratified into two categories on the basis of the type of chemotherapeutic regimen they received. RESULTS: In all, 46 patients were analyzed, with a median follow up of 26.6 months. The baseline characteristics (age, stage, PS, histology, and serum markers) were not different in the two treatment arms. There is no significant difference in the outcome with either of the chemotherapeutic modalities. VIP is less cost effective and more toxic compared to BEP. CONCLUSION: In view of the greater toxicity and cost of therapy, as well as lack of either overall or disease free survival advantage, VIP is not a preferred option for patients with high-risk germ cell tumors in the Indian setting and it is still advisable to treat patients with BEP.

Objective of the study is the retrospective evaluation of clinico-hematological and cytogenetic profile of patients with erythroleukemia (EL) in a south Indian population. Case records of all patients with acute myeloid leukemia seen in the Department of Medical Oncology at Kidwai Memorial Institute of Oncology, Bangalore, between January 1997 and December 2004 were reviewed. Clinical details were noted and slides were reviewed. A total of 326 AML patient were diagnosed of whom 14 patients had AML M6. Contribution of EL to all forms of AML was 4.3%. The mean age was 37.1+13.9 yrs (range: 16-65); most patients were in their 4th decade, with a male: female ratio of 3.67: 1. Mean duration of symptoms in the present series was 10.9+6.9 weeks. Cytogenetics were normal in 71% of cases, and minor abnormalities were observed in 21% of cases. As a conclusion relative low incidence of secondary EL, more frequent normal karyotype, and relatively younger age observed in our series makes the picture of EL in our subcontinent different from that in other series reported thus far.
