The trust, which runs Cheltenham General Hospital, Gloucestershire Royal Hospital and Stroud Maternity Unit, said the move was due to ‘ongoing staffing challenges and wider service pressures'.
The trust, which is experiencing a long-running pay dispute with phlebotomist staff, said it was unable to accept referrals until further notice.
A spokesperson said: ‘We are actively working with clinical divisions to explore all available options with the aim of securing a long-term sustainable future for prehabilitation support in Gloucestershire. Patients recently referred and currently in treatment will be directly contacted for further information and direct signposting.'
Launched in 2022, the service, which was delivered at various community locations, has provided personalised physical, nutritional and psychological support to people preparing for cancer treatment, helping patients build strength and resilience ahead of surgery, chemotherapy or radiotherapy.
The spokesperson added: ‘We remain focused on ensuring that patients continue to receive the information and support they need to optimise their physical and psychological health before and during cancer treatment. This includes collaboration with acute, community and voluntary sector partners.
‘We are fully committed to the principles and proven benefits of prehabilitation and to the continued development of high-quality cancer services for people across Gloucestershire.'
