Clinical Significance of Occult Central Nervous System Disease In Adult Acute Lymphoblastic Leukemia
January 14, 2019 updated by: Maria Ilaria Del Principe, University of Rome Tor Vergata
Clinical Significance of Occult Central Nervous System Disease In Adult Acute Lymphoblastic Leukemia: A Multicenter, Retrospective Study From The Campus All/Gimema Network
Central nervous system involvement at diagnosis remains an obstacle to a long-term cure of patients affected by acute lymphoblastic leukemia.
The investigators have previously reported that flow cytometry (FCM) is better than conventional cytology (CC) in demonstrating the presence of leukemic cells in the patients'(pts) cerebrospinal fluid (CSF), especially in samples with low cell counts.
In the framework of the national Campus ALL program aimed at improving the management of adult ALL patients in the context of the GIMEMA protocols, in the present study the investigators retrospectively evaluated the incidence of occult CNS positivity and its impact on outcome in 241 adult pts with newly diagnosed ALL from 13 centers.

Intervention / Treatment
Detailed Description
Demographic and of laboratory data of 241 adult patients with ALL were retrospectively recorded.
All patients underwent diagnostic lumbar puncture and each cerebrospinal fluid sample was examined by CC and FCM.
The investigators identified patients with the only FCM positivity and the investigators correlated this condition with clinical and of laboratory data and with clinical outcome.

acute lymphoblastic leukemia patients
We observed within adult patients with ALL three groups of patients: patients without central nervous system (CNS) involvement, patients with manifest CNS involvement and patients with occult CNS involvement.

We evaluated cerebrospinal fluids of patients with ALL by conventional cytology and by flow cytometry
