Abstract

Patients with newly diagnosed acute lymphoblastic
leukemia (ALL) at a single institution were analyzed
retrospectively. From 2006 to 2010, 47 patients were treated
using the MRC UKALLXII/ECOG E2993 protocol. Prior to
July 2005, 40 patients had been treated with the JALSG ALL
87 protocol. A complete remission (CR) rate of 91.5% was
achieved with the E2993 protocol, which was not significantly
higher than the 80% achieved using JALSG
(P[0.05). The median duration of CR in months was 19 for
all patients treated with the MRC UKALLXII/ECOG E2993
protocol. Ph? patients showed a median CR duration of
11.5 months, while Ph- patients had a significantly longer
CR duration of 19 months (P = 0.019). Further, Phpatients
at standard risk (stratified on the basis of age and
white blood cell count at diagnosis) had a CR duration of
21 months, which was significantly longer than the
12-month CR duration for the ten Ph- patients at high risk
(P = 0.001). Significant differences were found in the
2-year event-free survival and overall survival rates between
the MRC UKALLXII/ECOG E2993 and JALSG ALL 87
groups in the following three cohorts: all patients (P = 0.009

and 0.022, respectively), Ph- patients (P = 0.009 and
0.018, respectively), and standard-risk patients (P = 0.014
and 0.007, respectively). The overall mortality rate for
induction therapy in the MRC UKALLXII/ECOG E2993
group was 2.1% (1 of 47 patients). One or more instances of
grade IV myelosuppression occurred during induction therapy.
Among the non-hematological toxicities, alopecia and
elevated ALT and AST levels were the most common. The
levels of ALT and AST could be reduced to less than twofold
the normal values within 1–2 weeks. The data indicate that
the MRC UKALLXII/ECOG E2993 regimen is well tolerated
in Chinese adults with ALL and can improve survival
compared with the JALSG ALL 87 protocol. Risk stratification
at diagnosis based on age and WBC count is suitable
for adults with ALL, and it is necessary to adopt different
strategies as determined by diagnostic results. Lastly, Ph?
patients have an extremely poor prognosis.
