AbstractWe report on a patient suffering severe pain following a long-standing sacral chordoma in whom management of therapy and pain was extremely difficult. Because orally administered morphine was observed to be ineffective in the early stages of treatment, we tried to achieve pain relief by using epidural morphine. This was also unsatisfactory. Intrathecal infusion of morphine and bupivacaine through a catheter inserted at the L2-L3 level was also found to be ineffective; only a segment block was observed. A structural anomaly of the spine was suspected and confirmed by myelography, showing metastasis at L3. Pain relief improved when an infusion of morphine+bupivacaine was employed through a catheter placed at the L4-L5 level below the blockage. A major problem which continued throughout the course of the disease was the daily occurrence of episodes of unbearable sharp pain that required addition of midazolam to the local anesthetic/opioid subarachnoid infusion. The patient received this mixture through an intrathecal port during the last 13 months of life, a gradually increasing dose being necessary. Periods of analgesia were followed by occasional crises of intense sharp pain suggesting incomplete relief. No serious complications or meningitis occurred. This case emphasizes the difficulty in managing pain in this type of cancer.
