Unexpectedly, the patient's calcium began to rise (Figure 1(a)) and on POD 4, total calcium was 14.3 mg/dL (ionized 1.8 mmol/L). Immunolocalization studies indicated that 1 alpha-hydroxylase was focally expressed in tumor cell cytoplasm (Figure 1(b)). Outpatient monitoring revealed stable calcium levels over time (Figure 1(a)).
