Pituitary alcohol injection for cancer pain. Use in a district general hospital.
The use of trans-sphenoidal pituitary alcohol injection was assessed in a district general hospital for the treatment of diffuse bilateral cancer pain in 26 patients. Fourteen patients received a total of 43 injections. Hormonal and non-hormonal dependent cancers were treated, with complete pain relief in ten patients and partial relief in a further seven patients. The duration of relief was variable, and usually less than 6 weeks, although two patients had complete pain relief for 5 and 7 months respectively. No cases of meningitis or cerebrospinal fluid rhinorrhoea occurred. Nasal antiseptics and vasoconstrictors were not used. Temporary pupil dilatation occurred in eight patients, of whom one had prolonged blurred vision for small print. Transient diabetes insipidus was common (53%), although only five patients needed permanent treatment. Death from their disease occurred in 65% of patients within 3 months. Survival was shorter than in series from specialist centres, suggesting later referral for pain relief. The technique is an inexpensive and valid form of treatment for cancer pain in a district hospital, but should not be undertaken lightly in view of the possible complications.
