Postmastectomy radiotherapy: clinical practice guidelines of the American Society of Clinical Oncology.

OBJECTIVE: To determine indications for the use of postmastectomy radiotherapy (PMRT) for patients with invasive breast cancer with involved axillary lymph nodes or locally advanced disease who receive systemic therapy. These guidelines are intended for use in the care of patients outside of clinical trials. POTENTIAL INTERVENTION: The benefits and risks of PMRT in such patients, as well as subgroups of these patients, were considered. The details of the PMRT technique were also evaluated. OUTCOMES: The outcomes considered included freedom from local-regional recurrence, survival (disease-free and overall), and long-term toxicity. EVIDENCE: An expert multidisciplinary panel reviewed pertinent information from the published literature through July 2000; certain investigators were contacted for more recent and, in some cases, unpublished information. A computerized search was performed of MEDLINE data; directed searches based on the bibliographies of primary articles were also performed. VALUES: Levels of evidence and guideline grades were assigned by the Panel using standard criteria. A "recommendation" was made when level I or II evidence was available and there was consensus as to its meaning. A "suggestion" was made based on level III, IV, or V evidence and there was consensus as to its meaning. Areas of clinical importance were pointed out where guidelines could not be formulated due to insufficient evidence or lack of consensus. RECOMMENDATIONS: The recommendations, suggestions, and expert opinions of the Panel are described in this article. VALIDATION: Seven outside reviewers, the American Society of Clinical Oncology (ASCO) Health Services Research Committee members, and the ASCO Board of Directors reviewed this document.

Side effects, quality-of-life issues, and trade-offs: the patient perspective.

Increasingly effective adjuvant treatments of invasive breast cancer and their widespread use have improved survival rates. Given the timing required by its use, adjuvant therapy requires the patient to absorb complex medical data and make challenging trade-offs shortly after initial diagnosis. However, many women are unprepared or unable to optimize adjuvant treatment decisions while experiencing the shock and dismay that often follow the confirmation of an invasive breast cancer diagnosis. Each woman needs to know the facts and circumstances of her own case and to fully understand the benefits and risks of adjuvant therapy. Only then can she, with her medical team, choose those therapies that will maximize her benefit as a patient and as a survivor in all aspects of her life, over both the short and longer term. To help the patient accomplish these goals, individualized practical knowledge that complements population-based advances in survival is critically needed. Considerable focus, study, and cross-disciplinary collaboration will be required to compile successful, integrated approaches to adjuvant therapy that reflect varying patient contexts and concerns. Other crucial ingredients are the investment of resources in recently established research fields (such as the tracking of psychosocial outcomes and delayed morbidity) and informed guidance from patient advocates. To accelerate patient-centered progress in adjuvant therapy for breast cancer, areas that need attention include targeted public education programs; patient information and informatics; treatment selection and decision-making tools; and interventions and therapies to improve quality of life for patients, survivors, and their families. Underlying all of these efforts should be culturally competent, multigenerational approaches to communicating effectively with diverse patients and family members in multiple clinical and community settings.
