ABSTRACT

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.

ABSTRACT

BACKGROUND: Febrile neutropenia (FN) is a common but serious complication of chemotherapy in patients with solid tumors (ST) and hematological malignancies (HM). The epidemiology of FN keeps changing. OBJECTIVE: The objective was to study the epidemiology of FN in adult patients with ST and HM at Kidwai Memorial Institute of Oncology, Bangalore - A tertiary cancer care center. MATERIALS AND METHODS: Data of all episodes of FN that occurred during the period July 2011 to December 2011 were collected prospectively and analyzed. RESULTS: A total of 75 episodes of FN was observed during study period involving 55 patients. Febrile neutropenic episodes were more frequent in HM than in ST (57% vs. 43%). The rate of bloodstream infection was 14.7%. Gram-negative organisms were the predominant isolates (56.25%). Overall mortality rate was 13.3%. Presence of medical co-morbidity and positive culture predicted high mortality. Mortality rate did not differ significantly between HM and ST (14% vs. 12.5%; P = 1.0). Gram-positive bacteremia was associated with greater mortality than Gram-negative bacteremia (P = 0.02). CONCLUSION: Empiric antibiotic treatment for FN should be tailored to the locally prevalent pathogens and their susceptibility patterns.

ABSTRACT

Head and neck cancers comprise a heterogenous group of cancers that require a multidisciplinary approach. Last few decades have seen an increasing role of chemotherapy with intent of treatment shifting from palliation to cure. We performed a thorough search online and offline for all relevant articles of chemotherapy in head and neck cancer. Cancers of nasopharynx and salivary glands were excluded.

ABSTRACT

BACKGROUND: Systemic anaplastic large cell lymphoma (ALCL) accounts for 2-8% of non-Hodgkin's lymphoma in adults and 10-15% in children. While there is ample data in the world literature about the clinical features and outcome of this disease, prognosis in Indian patients is largely unknown. OBJECTIVE: To study the clinical, pathologic profile and outcome ALCL. MATERIALS AND METHODS: Fifty patients who had pathologically proven diagnosis of systemic ALCL at our institute from June 2003 to May 2011 were included for retrospective analysis. This included 30 cases of anaplastic lymphoma kinase+ (ALK+), ALCL and 20 cases of anaplastic lymphoma kinase- (ALK-), ALCL. The hospital protocol for treatment of these patients included CHOP chemotherapy regimen in >15 years of age and MCP842 protocol with vinblastine for 1 year in <15 years of age. Event free survival was noted. These outcomes were correlated with ALK status, International Prognostic Index (IPI) score, and stage at presentation. RESULTS: At a median follow-up of 36 months (range: 6-72 months) ALK- ALCL had a poor outcome. The 3 year event free survival in pediatric ALCL was 66.7%. In adults, this was 60% ALK+ ALCL was 60% and 20% in ALK- ALCL. CONCLUSIONS: Systemic ALCL is an aggressive disease. CD3 + positivity is commonly seen in ALK- ALCL and ALK+, epithelial membrane antigen + positivity is seen in ALK+ ALCL. ALK- ALCL, advanced stage III, IV and high IPI score were associated with poor prognosis. The demographic profile and outcome in our study was similar to the world literature. With new drugs like crizotinib and brentuximab vedotin the future looks very promising.

ABSTRACT

Chronic myeloid leukemia (CML) is a rare disease in children, accounting for 2-3% of leukemias in this age group. Few studies have reported on efficacy of imatinib in childhood CML. The purpose of this retrospective study was to determine the efficacy of imatinib in children. A total of 43 patients from age 7 years to 20 years with newly diagnosed CML received imatinib daily at 260 mg/m(2). Response rates, survival and toxicity were evaluated. The median follow-up was 43 months. All patients achieved a complete hematological response. Twenty-five (58.1%) patients achieved a complete cytogenetic response and 18 (41.9%) achieved a major molecular response at any time during their follow-up period. Both overall survival and progression-free survival at 43 months' median follow-up were 100%. Event-free survival was 92.8%. Imatinib was well tolerated. We conclude that imatinib is effective in children and adolescents with CML.

ABSTRACT

Soft tissue sarcomas (STS) comprise 1% of all cancers diagnosed worldwide with more than 40 different histological subtypes each with distinct underlying biology, natural history and response to treatment. Due to the differential chemosensitivity it is imperative to have a correct histological diagnosis for optimal treatment of these patients. Even though surgery remains the primary modality of treatment there is increasing specialization of chemotherapy with respect to histological subtype. In general there is no place for "one size fits all strategy". To correctly define the role of chemotherapy, an extensive search was carried out online and offline for all relevant articles concerning chemotherapy in soft tissue sarcoma. This review aims to discuss the evolution of chemotherapy, its present role in neoadjuvant, adjuvant, metastatic settings and exciting trends with the advent of targeted therapies.
