I'm looking for clinical trials or experience in treating CNL which is very rare.
CHRONIC NEUTROPHILIC LEUKEMIA (CNL)
I have reviewed this rare disorder recently, and I believe the references below provide some of the more important and valuable resources on chronic neutrophilic leukemia (CNL), right up to current date [2014].
The core basics of chronic neutrophilic leukemia (CNL) are provided in several papers that elucidate diagnosis, natural history, treatment and management [1-6]. In addition several case reports and reviews provide distillations of the medical literature to date of publication (latest, to 2013) [7-10].
MOLECULAR STUDIES
Another set of papers focuses on the genetics/genomics and underlying pathogenic pathways of CNL [11-18, 21-23], especially JAK2 gene mutation [12,13,15,16,18], several with extensive recent reviews of the literature [13,15]. In addition, given that distinguishing CNL from secondary neutrophilia is often a diagnostic dilemma, it's been suggested that the detection of the V617F JAK 2 mutation can function as a differential diagnostic test to establish the neoplastic nature of the neutrophilia [19], as well as render patients with CNL and JAK2 mutation potential candidates for molecular-targeted therapy [23], a while a just published [2014] study suggests that both JAK2 V617F-positive neutrophilia as well as CSF3R mutations should now be requisite diagnostic criteria for CNL [20]. And another recent study provides for the first time extensive molecular and expression data of multiple genomic alterations in CNL, far beyond just JAK2 and CSF3R mutations [22].
EXTRACTING FURTHER LITERATURE
The references are deliberately selected (those unavailable even in abstract form have been omitted), but should you want to extract a wider comprehensive listing, then enter the following as the search term in PUBMED
"chronic neutrophilic leukemia"[TIAB]
which should return some 174 results (inclusive of my own selective references).
