In a phase II trial involving 31 patients with breast cancer who had expe-
rienced progressive bone metastases or skeletal-related events (SRE) while
on pamidronate benefit was seen by switching to the more potent zole-

cant reductions in both severity of pain (p<0.001) and urinary markers
of bone turnover (P=0.008).
Answer 40.16. The answer is E.
Contraindications to peritoneovenous shunts include chylous and hemor-

occlusion. Also underlying cardiac, pulmonary, and renal insufficiency
could be exacerbated from the increased volumes draining via the perito-
neovenous shunts.
