In addition to a complete medical history and physical examination, diagnostic procedures for acute myeloid leukemia (AML) may include the following:

  • Additional blood tests and other evaluation procedures
      
  • Bone marrow aspiration and/or biopsy - a procedure that involves taking a small amount of bone marrow fluid (aspiration) and/or solid bone marrow tissue (called a core biopsy). The fluid and tissue usually come from the hip bones. They are examined for the number, size, and maturity of blood cells and/or abnormal cells. It is also used to do the chromosome analysis on these cells.
      
  • Spinal tap/lumbar puncture - This is only done in special cases when there is suspicion that the leukemia may have involved the brain. This is rarely discovered at the time of diagnosis, perhaps in only 1 percent of cases. A special needle is placed through the lower back into the spinal canal. The canal is the area around the spinal cord. The pressure in the spinal canal and brain can then be measured. A small amount of cerebral spinal fluid (CSF) can be removed and sent for testing to determine if there is an infection or other problems. CSF is the fluid that bathes the brain and spinal cord.

ACS Guidelines for Breast Screening with MRI May Be Excluding Some High-risk Women

January 6, 2009 — The American Cancer Society (ACS) has developed a set of guidelines to recommend which high-risk women need to undergo screening with breast magnetic resonance imaging (MRI); however, these guidelines may unwittingly exclude some women who are at a high risk of carrying the BRCA mutation yet still don’t meet the limitations set by the ACS. The results of this study were published in the journal Cancer.

Colonoscopy Fails to Identify Many Colorectal Cancers

January 6, 2009 — Colonoscopy, a standard screening method for colorectal cancer, misses the majority of cancers on the right side of the colon and about one-third of cancers on the left side of the colon, according to the results of a study published in the Annals of Internal Medicine. The researchers estimated that the screening method may reduce colorectal cancer mortality by 60-70%, rather than 90% as previously estimated.

High-dose Faslodex® Improves Time to Progression Compared with Arimidex® as Initial Therapy in Advanced Breast Cancer

January 6, 2009 — Researchers affiliated with an international trial have reported that high-dose Faslodex® (fulvestrant) significantly improves time to cancer progression compared with Arimidex® (anastrozole) as initial therapy for hormone-positive, advanced breast cancer. These results were recently presented at the 2008 annual San Antonio Breast Cancer Symposium December 10-14, 2008.
