Case ReportsMethadone analgesia in cancer pain patients on chronic methadone maintenance therapy.
Methadone is currently best known for its use as the maintenance drug in opioid addiction. The main concern when using methadone for the treatment of pain is its long and unpredictable half-life, which is associated with the risk of delayed toxicity. This may result in side effects such as sedation and respiratory depression if careful titration and close observation of individual patient responses are not performed. ⋯ The first five patients were at least partially refractory to the analgesic effects of opioids other than methadone. All six patients achieved analgesia without sedation or respiratory depression from aggressive upward methadone titration. Methadone analgesia can be considered early in the course of treatment of patients with chronic exposure to methadone who develop new or worsening pain requiring opioid therapy.

Breathlessness leading to exercise limitation is common in patients with advanced cancer and is ineffectively treated. There are few research data to guide clinicians on best practice. The shuttle walking test has been validated for some conditions such as chronic obstructive pulmonary disease but not for advanced cancer. One of the well documented difficulties of doing clinical research in palliative care is the acceptability of assessment tests. This study examined the reproducibility of the shuttle walking test in patients with advanced cancer to help facilitate the systematic evaluation of interventions designed to improve breathlessness. ⋯ The shuttle walking test is a reproducible test of functional capacity in ambulant patients with advanced cancer, WHO performance status 1 or 2. The data indicate that a practice session is needed. It is easy to carry out and acceptable for patients with advanced cancer.

The concept of palliative care differs according to cultures and traditions. In Spain, palliative care programs have expanded in recent years. The European Commission Research Project in Palliative Care Ethics has sponsored ongoing research to analyze and clarify the conceptual differences in providing palliative care to patients in European countries with diverse cultures and backgrounds. ⋯ The Spanish palliative care movement has shifted its focus from starting new programs to consolidating and expanding the training of the professionals already working in the existing programs. Although there is a general consensus that a new philosophy of care is needed, the interpretation and application of this general philosophy are different in diverse sociocultural contexts.
