Assessment of hormone receptors (estrogen and progesterone) helps to direct therapy for women with breast cancer. Immunohistochemistry is most commonly used to assess hormone receptor status and it is essential that these tests are performed accurately and reliably within and across laboratories. The overall purpose of this guideline is to improve the quality and accuracy of hormone receptor testing and its utility as a prognostic and predictive marker for invasive and in situ breast cancer.

Purpose: To develop a guideline to improve the accuracy of immunohistochemical (IHC) estrogen receptor (ER) and progesterone receptor (PgR) testing in breast cancer and the utility of these receptors as predictive markers.

Methods: The American Society of Clinical Oncology and the College of American Pathologists convened an international Expert Panel that conducted a systematic review and evaluation of the literature in partnership with Cancer Care Ontario and developed recommendations for optimal IHC ER/PgR testing performance.

Results: Up to 20% of current IHC determinations of ER and PgR testing worldwide may be inaccurate (false negative or false positive).

PURPOSE To develop an evidence-based guideline on the use of 5-alpha-reductase inhibitors (5-ARIs) for prostate cancer chemoprevention. METHODS The American Society of Clinical Oncology (ASCO) Health Services Committee (HSC), ASCO Cancer Prevention Committee, and the American Urological Association Practice Guidelines Committee jointly convened a Panel of experts, who used the results from a systematic review of the literature to develop evidence-based recommendations on the use of 5-ARIs for prostate cancer chemoprevention. Results The systematic review completed for this guideline identified 15 randomized clinical trials that met the inclusion criteria, nine of which reported prostate cancer period prevalence.

Purpose: To update a clinical practice guideline on the use of chemotherapy and radiation therapy protectants for patients with cancer.

Methods: An update committee reviewed literature published since the last guideline update in 2002.

Results: Thirty-nine reports met the inclusion criteria: palifermin and dexrazoxane, three reports (two studies) each; amifostine, 33 reports (31 studies); and mesna, no published randomized trials identified since 2002.

The American Society of Clinical Oncology (ASCO) published its first clinical practice guideline, which focused on the use of hematopoietic colony-stimulating factors, in 1994. Since then, ASCO has published 24 additional guidelines or technology assessments on a range of topics and is developing 11 additional guidelines. Guidelines are among ASCO's most valued products, according to membership surveys and data from the JCO.

Purpose: To update the American Society of Clinical Oncology/American Society of Hematology (ASCO/ASH) recommendations for the use of epoetin. The guideline was expanded to address use of darbepoetin and thromboembolic risk associated with these agents.

Method: An Update Committee ("Committee") reviewed and analyzed data published since 2002 through July 2007.

Purpose: To review the evidence on the incidence of long-term cardiac or pulmonary toxicity secondary to chemotherapy, radiotherapy, or trastuzumab in symptomatic and asymptomatic cancer survivors.

Methods: An American Society of Clinical Oncology Panel reviewed pertinent information from the literature through February 2006.

Results: Few studies directly addressing the benefits of screening for long-term cardiac or pulmonary toxicity in asymptomatic cancer survivors who received chemotherapy, radiotherapy, or trastuzumab were identified.

Purpose: To develop a guideline to improve the accuracy of human epidermal growth factor receptor 2(HER2) testing in invasive breast cancer and its utility as a predictive marker.

Methods: The American Society of Clinical Oncology and the College of American Pathologists convened an expert panel, which conducted a systematic review of the literature and developed recommendations for optimal HER2 testing performance. The guideline was reviewed by selected experts and approved by the board of directors for both organizations.
