Introduction: Prevalence of C in C-PAT under opioid therapy has been studied in centres from Europe, USA, Canada and Chile, while no specific data is available from Argentina. Studies informed that even a high prevalence C rate of 60-90% of CPAT, it is often underdiagnosed in clinical practice.

Aims: To describe prevalence of C (evaluated with Fallon C score) in a population of C-PAT who suffer from cancer-related pain and receive opioids; to relate C with daily opioid dose and performance status (PS); to describe C-related symptoms and patients´ perceptions on C and quality of life (QL).

Methodology: A questionnaire including 17 main topics was performed by trained palliative care nurses to 200 C-PAT under opioids, who received medical median time of follow-up was 16 days. 34 doses were used and the positive response was achieved in 62%. Laxation after the first dose before 24 hours was reported in 81%. 3 patients received a second dose after the first 24h without response. Adverse events were reported in 7 patients (4 showed abdominal pain and 2 diarrhea). Treatment was discontinued due to side effects.

Conclusions: Our data show similar response rate that previously published. Response is achieved in the majority of cases (81%) within the first 24 hours showing an acceptable tolerance profile (75%) suggesting a better selection of patients must be pursued.
