Admission Diagnosis: Breast cancer with osteoporosis
Hospital Course: The patient was diagnosed with breast ca in July 2010 and underwent surgery, radiotherapy, and chemotherapy. In February 2011, AI therapy with letrozole was initiated for 5 years. A DXA scan in March 2011 revealed osteoporosis, with BMD T-scores of -2.9 at the lumbar spine and -1.9 at the total hip. The patient was started on antiresorptive treatment with denosumab every 6 months and received it for 12 half-yearly injections, with the last one administered in August 2016. As the patient ended letrozole treatment in November 2016, a DXA scan was performed that showed no more osteoporosis in the lumbar spine and total hip, and she continued receiving adequate daily calcium and vitamin D supplementation.

Follow-up and Outcome: A CTX in March 2017 was normal at 33 ng/L, but it increased to 2070 ng/L in August. As a result, antiresorptive treatment was initiated with raloxifene 60 mg daily, which was being taken regularly by the patient until mid-July when she started experiencing spontaneous low back pain. An MRI of the thoracolumbar spine revealed two fractures, with medullary edema at D11 and L5. The CTX also showed extremely high levels, and an emergency injection of denosumab was administered at the time of fracture diagnosis to rapidly reduce the increased bone turnover. 

Final Diagnosis:  Osteoporotic fractures with high bone turnover 

Discharge Plan: The patient was discharged after treatment with an injection of denosumab to help overcome the high bone turnover and reduce the risk of potential fracture. The patient was advised to increase her physical activity, maintain a healthy diet, and continue taking regular daily calcium and vitamin D supplementation. The patient was advised to follow-up and monitor her CTX levels at regular intervals for any signs of high bone turnover. She was also advised to contact her healthcare provider immediately if she experienced any new episodes of back pain.

Follow-up Plan: The patient was scheduled for follow-up appointments with the primary care provider and the endocrinologist to monitor and adjust her treatment as needed. The patient was advised to maintain a healthy lifestyle, increase her physical activity, incorporate weight-bearing exercises in her routine, and keep her body weight in a healthy range for optimal bone health.  Further, the patient was advised to avoid smoking and limit alcohol consumption to maintain optimal bone health.
