ABSTRACT
BACKGROUND:
The association between the imaging response (structural or metabolic) to neoadjuvant chemotherapy (neoCT) before colorectal liver metastasis (CRLM) and survival is unclear.METHOD:
A total of 201 patients underwent their first CRLM resection. A total of 94 (47%) patients were treated with neoCT. A multivariable, Cox proportional hazard regression analysis was performed to compare overall survival (OS) and progression-free survival (PFS) between response groups.RESULTS:
Multivariable regression analysis of the CT/MRI (n = 94) group showed no difference in survival (OS and PFS) in patients who had stable disease/partial response (SD/PR) or complete response (CR) versus patients who had progressive disease (PD) (OS HR, 0.36 (95% CI 0.11-1.19) p = .094, HR, 0.78 (95% CI 0.13-4.50) p = .780, respectively), (PFS HR, 0.70 (95% CI 0.36-1.35) p = .284, HR, 0.51 (0.18-1.45) p = .203, respectively). In the FDG-PET group (n = 60) there was no difference in the hazard of death for patients with SD/PR or CR versus patients with PD for OS or PFS except for the PFS in the small CR subgroup (OS HR, 0.75 (95% CI 0.11-4.88) p = .759, HR, 1.21 (95% CI 0.15-9.43) p = .857), (PFS HR, 0.34% (95% CI 0.09-1.22), p = .097, HR, 0.17 (95% CI 0.04-0.62) p = .008, respectively).CONCLUSION:
There was no convincing evidence of association between imaging response to neoCT and survival following CRLM resection.
