100

Occurs in what percentage of cancer patients.

Occurs in ~20–30% of cancer patients.

100

Name 3 symptoms a patient may present with

  • Mild:
    • Fatigue
    • Constipation
  • Severe:
    • Confusion
    • Lethargy
    • Polyuria
    • Arrhythmias
100

First-line therapy for all symptomatic hypercalcemia

What is IV normal saline hydration?

100

Most common presenting symptom.

What is back pain?

100

This emergency is most associated with what type of cancers?

What is inter-abdominal?

200

Three cancers most commonly associated with this emergency.

What are breast, lung, and multiple myeloma?

200

Mechanism of hypercalcemia seen with bone metastases.

What is osteolysis from cytokine-induced bone resorption

200

Class of drugs that inhibit osteoclasts and are the mainstay of therapy.

What are bisphosphonates? 
200

 Immediate medication to start upon suspicion.

What is dex?

200

Two cancers most commonly associated with MBO.

What are ovarian and colorectal cancer?

300

What does hypercalcemia usually indicates about prognosis

What is advanced disease / poor prognosis?

300

Two non standard labs helpful in determining cause of hypercalcemia.

What are PTH and PTHrP?

300

Drug used for rapid but short-term calcium reduction.

What is calcitonin?

300

Imaging modality of choice.

What is MRI?

300

Classic symptom triad.

What is:

  • Nausea/vomiting
  • Abdominal pain
  • Constipation/obstipation
400

 Define corrected calcium.

What is 

Corrected Ca = total Ca + 0.8 × (4 – albumin)

400

In addition to advanced disease, high tumor burden, and bone mets, this common reason for hospitalization (for any patient) is a risk for hypercalcemia

What is dehydration?

400

Targeted therapy used in bisphosphonate-refractory cases.

 What is denosumab?

400

Common cancers causing spinal cord compression.

 What are lung, breast, prostate cancers? 

400

Pharmacologic agent used to reduce GI secretions in MBO.

What is octreotide?

500

The most common mechanism of hypercalcemia in malignancy mimics this hormone

What is PTH

500

Name the three mechanisms of malignancy-related hypercalcemia.

What are:

  • PTHrP secretion
  • Osteolytic bone metastases
  • Vitamin D–mediated increase in calcium
500

We would be able to use denosumab first line in patients with this issue

What is renal insufficiency?

500

Most important predictor of neurologic recovery.

What is pretreatment neurologic status?

500

Primary goal of treatment in advanced MBO.

What is symptom palliation and quality of life maintenance?
