Curative treatment incorporating subjective decisions on age and frailty is not beneficial for older patients with oral cavity squamous cell carcinoma.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The curative surgical treatment of older patients with oral cavity squamous cell carcinoma (OCSCC) is often personalized by incorporating subjective decisions on age and frailty. We aimed to determine here whether real-world recommended treatment, following official French guidelines only, versus deviation from recommended treatment was beneficial for older patients with OCSCC. To do this, we performed a retrospective evaluation of patients >70 years managed for treatment of p16-negative OCSCC in our tertiary hospital center in France between 2007 and 2017. The association between postoperative morbidity and deviation from recommended treatment was analysed using multivariate logistic regression. Cox Proportional Hazards Regression assessed the associations between deviation from recommended treatment and both the hazard of recurrence and mortality within 5 years. We included 185 patients who were recommended surgical resection of OCSCC: n = 147/185 (79%) patients underwent the recommended treatment and 38/185 (21%) patients underwent deviation from recommended treatment. Patients who underwent deviation from recommended treatment had a significantly lower recurrence-free survival (p = 0.0005) and overall survival (p = 0.008). Deviation from recommended treatment was found independently associated with increased development of 3-month postoperative morbidity (adjusted odds ratio 2.63 [1.23-5.82]; p = 0.02) and increased risk of recurrence within 5 years (adjusted hazard ratio 1.79 [1.14-2.83]; p = 0.01). Deviation from recommended treatment was not found independently associated with increased risk of mortality within 5 years (1.35 [0.82-2.23]; p = 0.2). Overall, deviation from recommended treatment was associated with worse outcomes and so we have identified a decision-making process biased by undocumented and subjective evidence. Preoperative risk models therefore require further validation in older patients with OCSCC to define more appropriate treatment regimens.
