Background:
To assess the frequency of patient-reported outcomes (PROs) and non-PROs in randomized controlled trials (RCTs) addressing head/neck cancers.
Methods:
We included RCTs about interventions to treat head/neck cancers. PubMed was searched on September 16, 2022 and included studies published during three periods (2000-2002, 2010-2012, and 2020-2022). Data on types of outcomes and instruments to measure them were extracted and organized into PROs and non-PROs, and temporal trends for reporting outcomes were determined.
Results:
There was a reduction in the frequency of non-PROs (40% to 22%) and an increase in PROs (5% to 19%) over 20 years. The frequency of reporting both non-PROs and PROs seemed to be stable over the same period (55% to 58%). A great variety of instruments to measure PROs and non-PROs was identified.
Conclusions:
There has been a growth in the types of PROs in more recent years, and they were more frequently reported in RCTs. However, head/neck cancer trials with a combination of PROs and non-PROs were the most prevalent.

Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...

02:49Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
