Lack of treatment-related mortality definitions in clinical trials of children, adolescents and young adults with lymphomas, solid tumors and brain tumors: a systematic review.


ABSTRACT:

Background

There is a lack of standardized definition for treatment-related mortality (TRM), which represents an important endpoint in cancer. Our objective was to describe TRM definitions used in studies of children, adolescents and young adults with lymphomas, solid tumors and brain tumors.

Methods

We conducted a systematic review of studies enrolling children, adolescents and young adults with lymphomas, solid tumors and brain tumors in which an anti-cancer intervention was randomized, or all study designs in which TRM was a primary or secondary outcome. We searched Ovid MEDLINE, EMBASE and Evidence-Based Medicine Reviews from 1980 to June 2013. Two reviewers evaluated study eligibility and abstracted data.

Results

In total, 67 studies were included and consisted of 62 randomized therapeutic trials and 5 TRM studies. None of the studies (0/67) provided a definition for TRM. Only one randomized trial of rhabdomyosarcoma provided a definition of early death.

Conclusions

We were unable to identify any TRM definitions used in studies of children, adolescents and young adults with lymphomas, solid tumors and brain tumors. Given that a proportion of this patient population may receive intensive treatment, there is an urgent need for consensus-based definitions of TRM for use across clinical trials.
