Only a handful of NHS trusts are using the cancer app on the controversial £330 million Federated Data Platform (FDP) run by Palantir, while newly released figures raise questions about which trusts are benefiting. Cancer 360 was designed to bring cancer patients’ data from disparate spreadsheets and electronic health records into a central system, helping health professionals prioritize treatment. Pilots began four years ago, and trusts are not charged directly for the FDP. Yet official figures put Cancer 360’s uptake at just five or six trusts. Freedom of Information responses gathered by grassroots campaign group No Palantir in the NHS also reveal discrepancies between reported benefits and recorded use. In June 2025, NHS England said that Cancer 360 "drastically cut down diagnosis times" and referred to a pilot at Chelsea and Westminster NHS Foundation Trust, which saw the proportion of patients diagnosed within 28 days climb from 72 percent to 85 percent. The trust began trials in 2022, while working with Palantir under a £23 million contract awarded without competition, before the US firm was awarded the FDP contract in late 2023. Critics argued the FDP procurement was flawed as Palantir had developed use cases under £60 million in non-competitive contracts which were then carried over to the FDP. Last year, NHS England said Cancer 360 served 46 registered teams and 239 active users, and processed 52,000 patients. In June 2026, NHS England said there were five trusts using Cancer 360 as of March 2026. Of those, only two were listed as benefiting. In July, health minister Preet Kaur Gill repeated the five-trust usage figure in a Parliamentary answer . Official data released in October said that as of June, six trusts were using Cancer 360 and five were benefiting, but did not identify the trusts or explain the increase. The stats have since been removed from the NHS England website but are archived here . In June, NHS England responded to a Freedom of Information request . It said six trusts reported unique users logging into the Cancer 360 app over the last 12 months. However, two trusts cited as having run successful pilots – Chelsea and Westminster Hospital and Royal United Hospitals Bath – were listed as having zero unique users logging into the system during that period, according to NHS England’s reply…
