AI-generated summary

Anthony Sissons, aged 38, died of metastatic renal carcinoma while under a Mental Health Act inpatient treatment order. He presented to hospital on three separate occasions (13-15 June 2012) with constipation, which was treated conservatively without imaging to exclude serious pathology. A large aggressive renal tumour with hepatic invasion was ultimately diagnosed on 17 June after he re-presented with ongoing symptoms. His mental health condition (schizoaffective disorder) complicated assessment and cooperation with investigations. The coroner found no criticism of the initial medical management, noting that early diagnosis would unlikely have changed the outcome given the advanced cancer stage. The case highlights how mental health comorbidity and poor historian reliability can delay serious diagnosis, and suggests opportunities for enhanced screening during routine mental health monitoring.

  • delayed diagnosis of underlying malignancy

Coroner's recommendations

  1. Forward the finding to the Minister for Mental Health to consider the suggestion that people subject to community treatment orders could have additional tests performed when undergoing routine lithium level or medication level checks periodically, to identify potential anomalies indicative of serious underlying conditions
