Comparison of surgical and non surgical treatment strategies for non metastatic oropharyngeal cancer using inverse probability weighting.
Article in Discover oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveSurgical (SS) and non-surgical strategies (NSS) are both considered as valid options in the therapeutic management of oropharyngeal squamous cell carcinoma (OPSCC) because of the absence of randomized control trial.
methodThe objective of this retrospective cohort study was to compare the efficacy of SS versus NSS on overall survival (OS) and disease-free survival (DFS) in non-metastatic OPSCC. The study included patients treated in two centers between 2012 and 2020 treated by upfront surgery in SS group and other therapies in NSS. A Cox model allowed to estimate hazard ratios and 95%CI., Weighting by the inverse probability of a propensity score was applied due to the absence of randomization.
resultsWe analyzed 432 patients with a majority (71%) of male patients and a mean age of 62.6 (SD10.1), HPV prevalence of 70%, 61% were smokers. The 5-year OS and DFS were 59% (95%CI 54–64) and 61% (95% CI 56–66), respectively. The sample was split into SS (n = 254) and NSS (n = 178). Patients exposed to SS were statistically younger (p < 0.001), with a better performance status (PS) (p < 0.001), and less advanced TNM stage (p < 0.001). After weighting, the two groups were comparable. The weighted HR of SS versus NSS were 0.65 (95%CI 0.45–0.95, p = 0.02) and 0.67 (95%CI 0.47–0.94, p = 0.02) for OS and DFS respectively. Further sensitivity analysis confirmed these results.
conclusionsWhile our findings suggest potential benefits of SS, ongoing controlled randomized trials are essential to conform these observations.
