Mantle Cell Lymphoma
Cytology
Typical (Classic)
Blastoid (Blastic)
small to medium-sized Ly with scanty cytoplasm, irregular nuclei, condensed chromatin. Rarely round nuclei (mimicking CLL), or abundant pale cytoplasm (mimicking Marginal Zone Lymphoma)
Classic Blastoid Variant: medium-sized Ly with scanty cytoplasm and
round nuclei with finely dispersed chromatin and
high mitotic index
Pleomorphic Blastoid Variant:
heterogeneous large cells with irregular cleaved
nuclei, finely dispersed chromatin, small distinct
nucleoli
Nodular / mantle diffuse

Targeting BTK with Ibrutinib in Relapsed or Refractory Mantle-Cell Lymphoma Wang ML et Al NEJM 2013
UO Ematologia - Pisa
BKT inhibitor is a highly active new agent showing durable singleagent activity in relapsed and refractory mantle cell lymphoma.
The favorable toxicity profile suggests that ibrutinib provides the opportunity for treatment with less intensive and more effective regimens than those currently available

• phase III randomized trial • 280 patients in < 1 year • response rate was 72% with ibrutinib vs 40%
with temsirolimus • median progression-free survival was 14.6 vs 6.2
months. Median duration of response was not yet reached for ibrutinib
• response of ≥ 18 months occurred in 58% of ibrutinib responders vs 20% of temsirolimus responders

Ibrutinib in Relapsed Mantle Cell Lymphoma Mitchell R. Smith 2016
• Ibrutinib is a marvelous addition to mantle cell lymphoma treatment options. There remains room for improvement, however, as mantle cell lymphoma in one of three patients does not respond to ibrutinib, and with median follow-up of 20 months fewer than 50% of patients remain on ibrutinib therapy.
