Randomized Controlled Trial Clinical Trial
A randomised controlled study on the use of anti-inflammatory drugs in patients with cancer pain on morphine therapy: effects on dose-escalation and a pharmacoeconomic analysis.
The role of non-steroidal anti-inflammatory drugs (NSAIDs) in cancer pain has been well established in the treatment of mild pain and in association with opioids in the treatment of moderate to severe pain. The aim of this study was to verify the effects of NSAIDs on morphine escalation in advanced cancer patients with pain followed-up at home and to assess the pharmacoeconomic implications. A prospective randomised controlled study was carried out in 156 consecutive advanced cancer patients with pain followed-up at home in the period December 1999-December 2000. ⋯ The use of NSAIDs reduces the need for an opioid dose escalation or allows the use of lower doses. Their use is associated with a more intense gastric discomfort, but results in less opioid-related constipation. The eventual additive cost for NSAIDs therapy is negligible, especially in patients taking high doses of morphine.

Comparative Study
Does radical surgery to the axilla give a survival advantage in more severe breast cancer?
There is some evidence that more radical treatment of the axilla may improve survival in node-positive disease, but there are concerns about the resultant morbidity from axillary surgery and radiotherapy. The aim of this study was to compare the outcome of axillary node clearance with axillary sampling in similar patients by comparing loco-regional recurrence and overall survival. Patients with invasive breast cancer undergoing axillary surgery between 1986 and 1997 were included. ⋯ Local recurrence in the clearance group was 11% versus 6% in the sampled group, regional recurrence 2% versus 3% and distant metastasis 28% versus 13%. Kaplan-Meier analysis of the three prognostic groups for the clearance versus sampled groups showed no differences in the absolute survival (log rank: P=0.3, P=0.8 and P=0.6 for the good, moderate and poor prognostic groups, respectively). A conservative surgical approach to the axilla did not significantly increase the incidence of local or regional recurrence and the expected survival benefit from a radical axillary clearance was not apparent.
