The intention of a surveillance program to monitor prostate cancer patients is to detect recurrence of disease as soon as possible and institute therapy at the time of recurrence in order to improve the chance of cure or extend survival. We analyzed the cost of four surveillance programs for prostate cancer. As PSA levels are more sensitive than the bone scan, prostatic acid phosphatase and alkaline phosphatase, a surveillance program which utilizes these latter tests provides no additional clinically useful information beyond a PSA level and is costly. Adopting a strategy of eliminating these tests from a surveillance program would reduce national annual expense by approximately $1.5 billion in the year 2000. 相似文献

Breast cancer is the most common malignancy seen in women. Due to the increasing awareness for this disease and the increasing use of screening mammography, more patients are now diagnosed with early stage disease. Over the past few years, the indications for adjuvant treatment have expanded considerably, and more women are now candidates for chemotherapy, hormonal therapy, or both. The role of various prognostic factors and their implications on the design of a multidisciplinary therapeutic approach is discussed in this review. Current recommendations regarding the extent of the surgery, the role of radiation, and its integration to the adjuvant treatment are discussed. Guidelines on adjuvant chemotherapy and adjuvant hormonal therapy are also being presented. 相似文献

Inhibition of serine proteases by serpins (serpin: serine protease inhibitor) is a key mechanism for the control of proteolysis in thrombosis, shock, and inflammation. The various members of the serpin gene superfamily (α(1)-antitrypsin, ovalbumin, C1-inhibitor, antithrombin III, α(2)-antiplasmin, type-1 plasminogen-activator inhibitor, and so forth) have many characteristics in common. In this article, we review the biochemistry and cell biology of serpins, and we discuss their clinical importance and therapeutic potential. 相似文献

BACKGROUND: Patient-centered care requires that physicians understand patients' perspectives. Since the resident work hour rules were instituted, little information is available about how patients perceive these issues. Our objectives were to explore patients' knowledge, concerns, and attitudes about resident work hours, fatigue, and continuity of inpatient care and to evaluate the association between patients' trust and satisfaction with these concerns and attitudes. METHODS: We conducted a cross-sectional survey of 134 internal medicine inpatients at 3 institutions including a tertiary care academic health center, a Veterans Affairs medical center, and a private community teaching hospital. RESULTS: Mean age was 59 (range, 24-90), with 60% men and 70% white. Most patients agreed (50%) or felt neutral (38%) toward resident work hours being limited. Patients estimated that residents worked 60 h per week but thought that they should work no more than 51 h per week (p < .01 for the difference). Twenty-seven percent of patients had some concern about fatigue in the residents, and 28% reported concern about how often hand-offs of care occurred. Factor analysis yielded 3 factors: "worried about discontinuity/fatigue," "attitude toward resident/nurse work hours," and "perceived resident/nurse fatigue." In multivariable analyses, the "worried about fatigue/discontinuity" factor significantly predicted trust and satisfaction, and the "perceived resident/nurse fatigue" factor also predicted satisfaction. CONCLUSIONS: Some inpatients are concerned about both fatigue in resident physicians and discontinuity of care. This may play a role in trust and satisfaction for patients. Taking steps to design systems to minimize fatigue and discontinuity would be ideal. 相似文献
