| Abstract | BACKGROUND: Comparative effectiveness of filgrastim, pegfilgrastim, and sargramostim in preventing hospitalization for febrile neutropenia (FN) during myelosuppressive chemotherapy has not been well characterized and is an important clinical question in oncology. METHODS: This study used a retrospective cohort design and US healthcare claims data. Source population included patients with solid tumors receiving filgrastim, pegfilgrastim, or sargramostim during their first observed course of chemotherapy between July 2001 and June 2007. For each patient, every unique chemotherapy cycle during the course was identified, along with each cycle in which filgrastim, pegfilgrastim, or sargramostim was administered by the fifth day of the cycle (ie, as prophylaxis). Risks of hospitalization for neutropenic complications (broad definition: admission with a diagnosis of neutropenia, fever, or infection; narrow definition: admission with a diagnosis of neutropenia) and for any reason were examined on a cycle-specific basis during all the cycles in which colony-stimulating factor prophylaxis was administered. Unadjusted and adjusted odds ratios (ORs) for hospitalization were estimated. RESULTS: Risk (unadjusted) of hospitalization for neutropenic complications (narrow definition) was 2.1% for filgrastim prophylaxis (n=8286), 1.1% for pegfilgrastim prophylaxis (n=67,247), and 2.5% for sargramostim prophylaxis (n=1736). Corresponding risks of hospitalization based on the broad definition were 4.0%, 2.6%, and 5.1%. Risks of all-cause hospitalization were 7.9%, 5.3%, and 9.6%, respectively. Adjusted odds of hospitalization were significantly higher for filgrastim [OR (range across the 3 alternative measures of hospitalization): 1.58-1.79; P<0.001] and sargramostim (OR: 1.89-2.68; P<0.001) versus pegfilgrastim. CONCLUSIONS: Risk of hospitalization for neutropenic complications during cancer chemotherapy is lower with pegfilgrastim prophylaxis than with filgrastim or sargramostim prophylaxis. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
