Abstract
This retrospective study describes the clinical progression of 12 cats with pituitary tumours treated with a coarse fractionated radiation protocol delivering a total dose of 37 Gy in five once weekly fractions. A pituitary macrotumour was identified in all 12 cats: 4 with neurological signs only and 8 with insulin-resistant diabetes mellitus secondary to acromegaly. One of the cats with central neurological signs died before completing the radiotherapy course; the remaining three had partial or complete remissions of their central neurological signs. Of the cats with unstable diabetes mellitus, five no longer required insulin therapy, one required less insulin and two became stable. The overall median survival time was 72.6 weeks; four cats died from related causes, two from unrelated problems and six remain alive. Radiation therapy is confirmed as an effective treatment for feline pituitary tumours, giving prolonged survival and control of both paraneoplastic and mass effect signs.
