description | Objectives
To evaluate the utility of perfusion MRI as a potential biomarker for predicting response to chemoradiotherapy (CRT) in locally advanced rectal cancer.
Methods
Thirty-nine patients with primary rectal carcinoma who were scheduled for preoperative CRT were prospectively recruited. Perfusion MRI was performed with a 3.0-T MRI system in all patients before therapy, at the end of the 2nd week of therapy, and before surgery. The
K
trans
(volume transfer constant) and
V
e
(extracellular extravascular space fraction) were calculated.
Results
Before CRT, the mean tumour
K
trans
in the downstaged group was significantly higher than that in the non-downstaged group (
P
= 0.0178), but there was no significant difference between tumour regression grade (TRG) responders and TRG non-responders (
P
= 0.1392). Repeated-measures analysis of variance (ANOVA) showed significant differences for evolution of
K
trans
values both between downstaged and non-downstaged groups (
P
= 0.0215) and between TRG responders and TRG non-responders (
P
= 0.0001). Regarding
V
e
, no significant differences were observed both between downstaged and non-downstaged groups (
P
= 0.689) or between TRG responders and TRG non-responders (
P
= 0.887).
Conclusion
Perfusion MRI of rectal cancer can be useful for assessing tumoural
K
trans
changes by CRT. Tumours with high pre-CRT
K
trans
values tended to respond favourably to CRT, particularly in terms of downstaging criteria.
Key Points
•
Perfusion MRI can now assess therapeutic response of tumours to therapy
.
•
Tumours with high initial
K
trans
values responded favourably to chemoradiotherapy
.
•
Perfusion MRI of rectal cancer may help with decisions about management
