Breast Cancer Survivors:

ABSTRACT: A key objective in the follow-up of women with a history of breast cancer is the detection of local and distant disease at a curable stage. Regular clinical examination and yearly mammography are the standard of care. No consistent evidence supports annual chest radiography, bone scans, or tests of serum tumor markers. Order laboratory or diagnostic tests only if indicated by clinical findings. Advise women to report new symptoms promptly rather than waiting for the next scheduled examination. Some evidence supports the use of venlafaxine for tamoxifen-associated hot flashes. Despite the increased incidence of endometrial carcinoma in women taking tamoxifen, routine endometrial biopsies are not recommended. Most experts advise that women with a history of breast cancer who wish to have a child wait 2 to 3 years before becoming pregnant.

Acute Low Back Pain:

ABSTRACT: Most patients with nonspecific low back pain recover spontaneously within 4 to 6 weeks. Patients who resume their normal activities as soon as possible generally recover faster than those who stay in bed; analgesics speed recovery. Sciatica is usually caused by a herniated disk. However, if the patient has a demonstrable neurologic deficit, obtain plain radiographs to rule out tumor, spondylolisthesis, fracture, and infection. Administer high-dose intravenous corticosteroids immediately to patients with suspected epidural compression syndrome. Back pain in a patient with a history of cancer may indicate metastasis to the spine. If a cancer patient has new or aggravated symptoms, start corticosteroid therapy and order plain radiographs and MRI scans.
