Abstract
The diagnosis of Mantle Cell Lymphoma (MCL) is rarely made in young adults as the disease
is most commonly encountered in middle age and elderly individuals. The currently available
therapeutic modalities including autologous Hematopoietic Stem Cell Transplantation (HSCT)
are not curative. Allogeneic HSCT with Reduced-Intensity Conditioning (RIC) therapy is usually
offered to transplant-eligible patients taking into consideration their old age and comorbid medical
conditions. We report a young patient who failed to achieve Complete Remission (CR) of her MCL
after receiving 8 cycles of intensive cytotoxic chemotherapy, commenced in August 2008, at King
Fahad Specialist Hospital (KFSH) in Dammam, Saudi Arabia. Later on the patient had an allogeneic
HSCT with myeloablative conditioning therapy performed at King Faisal Specialist Hospital
and Research Center (KFSH-RC) in Riyadh in February 2009. During her follow-up at KFSH in
Dammam, she developed hepatic Graft Versus Host Disease (GVHD) that was successfully treated
with steroids and cyclosporine-A. Eighteen months after her allograft, the patient had complete
resolution of her residual disease. Her MCL is still in CR more than 6 years after her HSCT.

Introduction
MCL is a rare but distinct subtype of B-cell Non-Hodgkin's Lymphoma (NHL) [1-4]. It accounts
for 2-10% of all NHLs [1,3-7]. It has male predominance with male: female ratio of 2-4:1 [1-4]. It
mainly affects middle age and elderly individuals with the median age between 60 and 70 years [1-
3,8]. MCL usually presents with stage III or IV disease. Bone Marrow (BM) involvement, extensive
lymphadenopathy and splenomegaly are the usual presenting manifestations [4]. However,
MCL may present with pancytopenia, leukocytosis, and extra-nodal sites such as gastrointestinal
involvement [4].
MCL is characterized by the chromosomal translocation t(11,14)(q13;q32) which results in the
over expression of the cell cycle regulator cyclin-D1 that, in turn, causes a disorder of regulation in
cell proliferation [1-4,7,8]. Although most patients with MCL follow an aggressive clinical course,
a subset of patients may have a more indolent disease course [8]. Despite the recently introduced
aggressive therapeutic interventions, the overall prognosis is usually poor and the median overall
survival is usually 3 to 7 years [4,6,9].
Case Presentation
A 23 year old Saudi female was diagnosed to have MCL; stage IV B bulky disease; at KFSH
in Dammam in early 2006. She presented with constitutional symptoms and generalized
lymphadenopathy. The initial diagnosis was made on the basis of a lymph node biopsy.
Unfortunately, the patient discharged herself against medical advice and she preferred to have
herbal and traditional therapies instead. However, on 26th of August 2008, she was readmitted to
KFSH in Dammam with progression of her lymphoma in the form of extensive lymphadenopathy,
particularly in the cervical area, hepatosplenomegaly and BM involvement causing pancytopenia:
White Blood Cell (WBC) count of 3.4 x 109/liter (L), Hemoglobin (Hb) of 4.9 grams/L and platelet
(PLT) count of 44 x 109/L). Lymph node and BM biopsies showed heavy infiltration by intermediatesized
lymphocytes that were positive for: CD20, cyclin-D1, CD5, CD10, BCL2, BCL6 and CD3.
The proliferation index, Ki67, was 30%. Other investigations showed:
LDH of 355 units/L, normal immunoglobulin levels, normal serum
protein electrophoresis and no evidence of central nervous system
involvement. After re-establishing the diagnosis of MCL, the
patient received 8 cycles of hyper-CVAD regimen of chemotherapy
[cyclophosphamide, vincristine, doxorubicin, dexamethasone]
alternating with high-dose methotrexate and cytarabine following
which a remarkable reduction in the bulk of her disease was achieved,
but she was left with approximately 15% residual disease. Later on, the
patient was referred to KFSH&RC in Riyadh for HSCT. As the patient
was young without comorbid medical conditions and because she had
residual disease at the end of her chemotherapy and as she was found
to have a healthy and an HLA identical sibling donor, it was decided
to go ahead with an allogeneic HSCT rather than an autologous
HSCT. She received a myeloablative allogeneic HSCT in February
2009. The conditioning therapy was composed of 12 Gy Total Body
Irradiation (TBI) and cyclophosphamide. After recovery of her blood
counts, she moved back to the Eastern Province to have follow-up at
KFSH in Dammam. Four months following her successful allograft,
she developed localized herpes zoster infection, which was treated
successfully with intravenous then oral acyclovir for 2 weeks. Six
months post-transplant, the patient developed moderate GVHD of
the liver, manifested by 3 to 4 fold elevation in her serum gammaglutamyl
transpeptidase and alkaline phosphatase levels. This form
of GVHD was treated successfully for 3 months with cyclosporine-A
and oral prednisolone. A chimeric study was done 6 months post-
HSCT and it showed a 100% donor chimerism for lymphoid as well
as myeloid cells. One year post-HSCT, the patient also underwent
restaging evaluation with Computerized Axial Tomography (CAT)
scan which showed further regression in the extent of her residual
disease to about 5%. Six months later, a new CAT scan was performed
and it showed no evidence of disease below or above the diaphragm.
Then the patient continued to have regular follow-up at our outpatient
clinic and she remained clinically stable. She was last seen at the HSCT
out patient clinic at KFSH in Dammam on the 9th of June, 2016. She
was totally asymptomatic and her physical examination showed no
new abnormality. Her complete blood count showed: WBC: 5.87 x
109/L, Hb: 13.4 grams/L and PLT: 249 x 109/L. Her renal, hepatic and
bone profiles were all within normal limits. No new medication was
prescribed and a new follow-up appointment was scheduled.
Discussion
There is no standard induction or first-line treatment for MCL
[10]. The first-line therapy in MCL is usually adapted to age and
comorbid medical conditions [11]. The available chemotherapeutic
as well as targeted therapies for MCL include: R-hyper-CVAD;
R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine
and prednisolone); R-DHAP (rituximab, dexamethasone,
high-dose cytarabine and cisplatinum), R-MACLO-IVAM-T
(rituximab, methotrexate, doxorubicin, cyclophosphamide,
vincristine, cytarabine, ifosfamide, cytarabine and etoposide
followed by thalidomide maintenance); lenalidomide; bortezomib;
bendamustine; flavoperidol; temsirolimus; abexinostat; ibrutinib
and the combination of cladrabine plus rituximab or mitoxantrone
[2,12,13]. R-hyper-CVAD has been shown to be tolerable and
effective induction therapy for untreated patients with MCL [10].
In patients with MCL, high-dose chemotherapy and autologous
HSCT have been performed both upfront and at relapse with varying
degrees of success [14]. In patients subjected to autologous HSCT,
CR can be achieved in approximately 80% of cases, but almost all
patients including responders will ultimately relapse [11,13]. Polychemotherapy
plus rituximab followed by autologous HSCT has
become the standard of care in young patients with MCL as this
strategy, compared to chemotherapy alone, has demonstrated higher
response rates in addition to improved progression-free survival as
well as the possibility of improved overall survival [11-13,15-18].
Advanced-stage MCL is a disease for which no proven curative
therapeutic strategy currently exists [14,18]. However, patients
with advanced-stage MCL treated with high-dose chemotherapy
plus rituximab followed by autologous HSCT have been shown
to have more prolonged survival compared to patients treated
with conventional chemotherapy [18]. Unfortunately, relapse/
refractory MCL carries a dismal prognosis [5]. For patients with
relapsed/refractory MCL, the results of autologous HSCT remain
unsatisfactory, while the timely application of non-myeloablative
allogeneic HSCT may be curative [4,9]. In patients with relapsed/
refractory MCL having chemo-sensitive disease, allogeneic HSCT
may be curative given the graft versus-MCL provided by this form of
transplantation [11].
The first evidence of graft versus malignancy in MCL was
demonstrated in the late 1990s and this proved the efficacy of
allogeneic HSCT in patients with MCL [19,20]. Later on, several
studies have shown that in patients with MCL, allogeneic HSCT is
the only therapeutic strategy with curative potential [1,5,11,15,21,22].
However, the main drawbacks of myeloablative allogeneic HSCT
are: (1) the procedure is only feasible for a small number of patients,
(2) the associated toxicities in the form of GVHD and infectious
complications and (3) the relatively high treatment-related mortality
(TRM). Hence, RIC-allogeneic HSCT is adopted in an attempt to
reduce the toxicities and the high TRM associated with myeloablative
allografts [15,20,21,23].
Studies have shown that myeloablative allogeneic HSCT is a
feasible and a promising therapeutic option for younger patients
with MCL who are fit for the procedure and who have no comorbid
medical conditions, while RIC-allogeneic HSCT is a valid choice
for patients who are still fit for the procedure but are old and have
medical comorbidities [5,11,20,21,24]. The indications for RICallogeneic
HSCT in MCL include: (1) relapsed but chemo-sensitive
disease including multiple relapses, (2) refractory disease or disease
poorly responsive to high-dose chemotherapy and (3) MCL relapsing
after autologous HSCT [5,9,11,23,25]. The conditioning therapies
utilized in RIC-allogeneic HSCT include low-dose TBI, fludarabine
and alemtuzumab [5,21]. The outcome of allogeneic HSCT in patients
with MCL can be improved further by: (1) optimal patient selection,
that is, younger patients with less comorbidities and who are more
fit for the procedure, (2) optimal timing of HSCT, (3) the use of less
toxic conditioning therapies, and (4) close monitoring of chimerism
and optimal use of donor lymphocyte infusions [13,23-25].
Our patient had advanced disease at presentation which
failed to respond completely to eight cycles of intensive cytotoxic
chemotherapy. The decision to proceed with a myeloablative
allogeneic HSCT rather than an autologous HSCT was based on
the following: (1) the young age of the patient, (2) the absence of
comorbid medical conditions, (3) the availability of an HLA-identical
sibling for allograft, and (4) having a significant residual disease
which was likely to cause an early post-HSCT relapse of her disease.
The development of GVHD was effective not only in controlling her residual disease but also in preventing later relapse due to the
associated GV lymphoma effect.
In conclusion: in young patients with MCL having no comorbid
medical illnesses and having an HLA-identical donor, allogeneic
HSCT with myeloablative conditioning therapy should be considered
as a potentially curative therapeutic intervention. In patients with
MCL subjected to allografts, graft versus disease effect may counteract
disease relapse and may abolish residual disease.
