OBJECTIVES: The purpose of this study was to retrospectively assess the incidence of bowel wall oedema on computed tomography (CT) in patients with renal cell carcinoma (RCC) treated with sunitinib, and to investigate its association with diarrhoea.
METHODS: We conducted a retrospective analysis of all RCC patients treated with sunitinib at our hospital between December 2005 and December 2011. The presence or absence of bowel wall oedema on these CT examinations was scored. The presence of diarrhoea preceding, during, or after sunitinib treatment was identified from the patient files and retrospectively graded.
RESULTS: For 54 of 87 patients, bowel wall oedema was present on at least one CT examination. Of these 54 patients, the right-sided colonic segment was affected in 87%. Diarrhoea was the most common reported adverse event during treatment, with 58 patients (67%) having grade 1/2 diarrhoea and 9 patients (10%) having grade 3. There was a statistically significant correlation between the incidence of CT-scored bowel oedema and diarrhoea during sunitinib treatment (P = 0.004).
CONCLUSIONS: This study shows a very high incidence of bowel wall oedema and a strong correlation between the incidence of bowel wall oedema and diarrhoea in patients treated with sunitinib.
KEY POINTS: • Sunitinib is routinely used in patients with advanced renal cell carcinoma. • Diarrhoea is the most common reported adverse event during sunitinib treatment. • Incidence of bowel oedema and diarrhoea during sunitinib treatment is correlated. • Radiologists should avoid misinterpretation of bowel oedema as infectious colitis.
