Objective To evaluate the quality of the papers on the randomized controlled trial（RCT） of colorectal cancer treated by traditional Chinese medicine（TCM）

and to discuss the existing problems. Methods The RCT literature on colorectal cancer treated by TCM in Chinese National Knowledge Infrastructure（CNKI） from January 1

1996 to August 31

2018 were searched by two researchers. The CONSORT 2010 Statement: updated guidelines for reporting parallel group randomized trials（referred to as Statement） was used to evaluate the quality of each item one by one

giving a "yes"or "no"judgment. The papers published from January 1

1996 to December31

2012

and from January 1

2013 to August 31

2018 were compared. Results Compared with the period from January 1

1996 to December 31

2012

the quality of RCT papers on TCM treatment of colorectal cancer published from January 1

2013 to August 31

2018 was significantly improved in the 8 items of scientific background（2 a）

division of labor and other RCT core methodological entries（P > 0. 05）. Conclusion After the publication of the Statement

the reporting quality of the RCT papers has improved

but the reporting quality of the core methodological items is still not high

which may be related to the low awareness of the Statement by the researcher

and may also be that the blinding and random hiding cannot be implemented due to great difficulty in preparing decoction placebo. It is recommended to change the dosage form and other methods to improve the problem

and recommend to refer to the Statement for reporting.
