External validation of a risk model of febrile neutropenia occurrence in patients with non-Hodgkin lymphoma


Schwenkglenks, Matthias; Bendall, Kate Louise; Pfeil, Alena M; Szabo, Zsolt; Pettengell, Ruth (2013). External validation of a risk model of febrile neutropenia occurrence in patients with non-Hodgkin lymphoma. Leukemia & Lymphoma, 54(11):2426-2432.

Abstract

Febrile neutropenia (FN) is a common and serious complication of chemotherapy treatment. Clinical risk models may help to identify patients at high risk of FN but must undergo external validation before implementation in medical practice. Therefore, this study externally validated previously published clinical models of FN occurrence during chemotherapy in 240 patients with non-Hodgkin lymphoma by using an independent observational dataset (n = 1829). The models demonstrated predictive ability, and validation criteria for predicting any cycle of FN were partially met but a larger than expected decrease in performance was noted (area under the receiver operating characteristic curve was 0.71 in the validation dataset and 0.83 in the training dataset). Age, weight, baseline white blood cell count and planned chemotherapy parameters were confirmed to predict FN risk. Chemotherapy dose reductions, dose delays and colony-stimulating factor use were confirmed as risk modifiers during treatment. Further work is needed to improve the predictive ability of FN risk models.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
