TP53 gene-mutation and protein expression of p53 are described as being of prognostic importance for the outcome of breast cancer. The present study was therefore carried out to evaluate whether TP53 mutation would be a feasible prognostic marker in the routine diagnostic evaluation of breast cancer, and, in particular, to analyse the relationship between TP53 mutation and nodal status. Tumour material was obtained from women with sporadic early breast cancer. ⋯ The same factors together with postmenopausal status were found to be significantly associated with increased risk of death. TP53 mutation is a strong marker for the prediction of overall and disease-free survival in breast cancer, irrespective of nodal status. A better understanding of the role of the p53 pathway, including analysis of different types of TP53 mutations, is required in order further to investigate the prognostic potential of this marker.

Randomized Controlled Trial Comparative Study Clinical Trial
Morphine or oxycodone in cancer pain?
Oxycodone is an opioid analgesic that closely resembles morphine. Oxymorphone, the active metabolite of oxycodone, is formed in a reaction catalyzed by CYP2D6, which is under polymorphic genetic control. The role of oxymorphone in the analgesic effect of oxycodone is not yet clear. ⋯ Liver dysfunction affected selectively either oxycodone or morphine metabolism. Three patients with markedly aberrant plasma opioid concentrations are presented. Significant individual variation in morphine and oxycodone metabolism may account for abnormal responses during treatment of chronic cancer pain.

Randomized Controlled Trial Clinical Trial
Treatment of breast-cancer-related lymphedema with or without manual lymphatic drainage--a randomized study.
A prospective randomized study was carried out to investigate whether the addition of manual lymphatic drainage (MLD) to the standard therapy could improve treatment outcome in women with lymphedema of the ipsilateral arm after breast cancer treatment. Forty-two patients were randomly assigned to receive standard therapy or standard therapy plus MLD 8 times in 2 weeks and training in self-massage. ⋯ The patients were followed-up for a total of 12 months. The study showed that both groups obtained a significant reduction in edema and that MLD did not contribute significantly to reduce edema volume.

The dynamics surrounding the patient and family facing a death as the 'unit of care' is discussed. Aspects of communication, openness within the family, especially concerning children and teenagers, and factors that enable a family to function under the stress of a loved one's terminal illness are explored. The use of a genogram in palliative care to help to piece together the family dynamics and available support is fundamental to the care for the whole family.
