IPM Take
This is not a lifestyle sermon. It is a surgical-readiness story. Endometrial cancer is strongly linked with obesity, and surgery can be made harder by excess weight and comorbidity. If short-term prehabilitation is feasible, then systems should stop treating dietetic support, behavioural coaching and perioperative optimisation as soft extras.
Executive Summary
The randomized ENDO-CARE feasibility trial tested an intensive preoperative weight-loss intervention for women with endometrial cancer and excess weight awaiting curative surgery. The trial was conducted across nine gynaecologic cancer centres in England. Among 72 analysed participants, women receiving the intervention lost a mean of 5.3 kg before surgery compared with 1.8 kg in routine care. 44% of women in the intervention group lost at least 5% of body weight compared with 12% in routine care. Postoperative complications occurred in 27% of the intervention group versus 51% with routine care, although the study was not powered to establish efficacy.
Why it matters
- Patients / advocates: Prehabilitation can support patients before surgery, but must be framed safely and without blame.
- Clinicians: Short surgical windows can still be used for meaningful preparation when structured support exists.
- Hospitals / providers: Dietitians, behavioural support and perioperative teams are infrastructure, not decoration.
- Public authorities: Obesity-linked cancers require treatment pathways that address risk without moralising the patient.
Endometrial cancer sits at the intersection of oncology, obesity, surgery and stigma. That makes it politically easy to mishandle.
ENDO-CARE gives the field a more useful way to talk. The study did not ask women to “try harder” before surgery. It tested a structured, time-limited, dietitian-supported programme in the narrow window before curative endometrial cancer surgery. The result: meaningful weight loss, high engagement, no serious adverse events, and a signal toward fewer postoperative complications.
That is not definitive proof. It is a feasibility trial. It was not designed to settle whether weight loss reduces surgical complications. The complication signal must remain hypothesis-generating.
But the implementation message is already clear. Prehabilitation cannot stay trapped in pilot projects while operating theatres absorb the consequences of poor preparation. If a patient can be supported before surgery, the system should have a pathway to do it.
The tone matters here. This cannot become another way to blame women with endometrial cancer for their disease or their surgical risk. The responsibility sits with the health system. It must provide dietetic support, safe protocols, behavioural coaching, monitoring and rapid access. It must ensure that prehabilitation does not delay cancer surgery or exclude patients who need treatment.
The political question is whether health systems are willing to invest before complications happen.
Too often, care pathways fund rescue better than readiness. ENDO-CARE suggests readiness may be achievable even within a short preoperative window. That should be enough to justify a serious implementation trial and a serious policy conversation.
