Q

Acute Lymphocytic Leukemia

Prognostic factors:

A
  • Age — the young fare better (< 30)
  • Blast count > 30,000 do poorly
  • Cytogenetics — hyperdiploidy is a good finding, whereas a Philadelphia chromosome t(9,22) is a poor prognostic finding

Q

Acute Lymphocytic Leukemia

Tx

A
  • Supportive care with transfusions
  • Leukophoresis is not usually necessary since the blasts are smaller and less likely to cause sludging

    • Induction chemotherapy using multi-drug regimens
    • Consolidation chemotherapy with multi-drug regimens for multiple cycles
    • Maintenance (different from Myeloid)
    • CNS prophylasxis intrathecal / radiation

Q

Treat a postmenopausal patient with newly diagnosed breast cancer with well-differentiated, estrogen receptor-positive/progesterone receptor-positive, HER2-negative breast cancer.

A

Aromatase inhibitors are the standard of care for postmenopausal women with these tumors.

Postmenopausal women with hormone receptor–positive breast cancer should take a 5-year course of an aromatase inhibitor as primary treatment or for an additional** 5 years after completing a **5-year course of tamoxifen therapy. In women who are initially treated with tamoxifen, an aromatase inhibitor may be started following 2 to 3 years of tamoxifen therapy to complete a total of 5 years of hormonal therapy.

Trastuzumab is indicated for tumors that overexpress HER2

Manage short-bowel syndrome
patient should receive a proton pump inhibitor (PPI) such as omeprazole. In patients who have undergone massive resection of the small intestine and are left with short-bowel syndrome, there is a tremendous surge of gastric acid in the postoperative period. The increased acid can inactivate pancreatic lipase, leading to significant diarrhea and possible ulceration in the remaining bowel. Therefore, all patients who have undergone significant bowel resection should receive acid suppression therapy in the postoperative period with a PPI. Although increasing the loperamide may help with diarrhea control, it will not target the underlying pathophysiology of the increased acid production and will not prevent small-bowel ulceration.
