Independent of Philips Respironics, in December 2021, an analysis was published in the American Journal of Respiratory and Critical Care Medicine  that did not find a higher risk of incident cancer among obstructive sleep apnea (OSA) patients who used a Philips Respironics PAP device as compared to OSA patients who used a PAP device from other manufacturers, or OSA patients without treatment. The analysis and conclusion were based on data from a large multicenter cohort study involving 6,903 OSA patients on PAP devices between 2012 and 2020, including 1,220 Philips Respironics PAP users.
In May 2022, an analysis was published online in the European Respiratory Journal  that concluded that sustained and adherent CPAP therapy of OSA using Philips Respironics devices, compared with other manufacturers’ devices, was not associated with an increased risk of cancer after a median follow-up time of 7.2 years. The analysis and conclusion were based on data from a large multicenter cohort study involving 4,447 OSA patients on CPAP devices between 2007 and 2018, including 1,648 Philips Respironics CPAP users. Philips Respironics was not involved in the study or the analysis.
