Intraventricular morphine administration for control of chronic cancer pain.


Twenty cancer patients with severe chronic pain have been treated with intraventricular morphine sulfate. Adequate pain relief until death was achieved in 10 patients; 1 patient has been treated for 9 months and is still being treated. In 2 patients, the effects of the morphine sulfate on their unilateral pelvic pain wore off after 4 and 6 months because of tumor progression. At that time, they underwent chordotomy procedures elsewhere. The treatment was discontinued in 4 patients for reasons other than inadequate pain relief, such as medical complications or resolution of pain. In 3 patients, the procedure was abandoned when emotional and psychological factors interfered with pain control. Dose requirements of intraventricular morphine sulfate varied greatly, depending on the total daily dose of systemic narcotic intake at the onset of the study. Intraventricular morphine sulfate is a feasible and reliable method to achieve pain relief in selected cancer patients with severe chronic pain when the maximum tolerated dose of systemic narcotic analgesics has become insufficient to control their pain.
