Optimal follow-up time for evaluatingobjective response to radiotherapy in patients with hepatocellular carcinoma: a retrospective study.

The objective response rates increased over time from 15.4% at 3 months to 71.8% at 6 months and 87.2% at 9 months. Age60 years old or older and post-radiotherapy α-fetoprotein concentrations higher than pre-radiotherapy concentrationspredicted delayed treatment response.The objective response rate continued toincrease over 9 months. Therefore, to fully evaluate the treatment response of HCC, we recommend continuous observationfor at least 9 months after radiotherapy. PMID: 25418189 [PubMed - as supplied by publisher]
