Toward an Efficient Healthcare System Some consume too much (Unnecessary care given) Some consume too little (Necessary care not given) We could decrease the waste and improve overall health! Evidence Based Medicine
14
Rudolph Ludwig Karl Virchow 1821- 1902
15
Virchow’s Accomplishment One of the first cellular pathologists Virchow’s node Defined conditions that cause thrombosis One of the initial description of leukemia Defined cancer as a disease involving uncontrolled cell growth Defined cancer using a light microscope on specimens obtained by autopsy
17
Virchow’s Accomplishments The definition of cancer used in 2010 is largely that of Virchow with minor modifications More than 160 years later, we still use his definitions using a light microscope. There is clear evidence that some early detected cancers do not poise a threat and do not need to be treated.
18
Overdiagnosis Cure is Possible but not Necessary Prostate Cancer Breast Cancer Lung Cancer (NSCLC) Cervical Disease Renal Cancer Melanoma Colon Cancer
19
Overdiagnosis Cure is Possible but not Necessary In the US, it is estimated: More than half of all screen diagnosed prostate cancers At least fifteen percent of screen detected frank breast cancers. A larger proportion of Ductal carcinoma in situ (DCIS) Perhaps ten percent or more of lung cancers diagnosed through CT screening A large proportion of cervical dysplasia
20
A Genomic Definition of Cancer Genetics vs Genomics GeneticsGenetics is the study of heredity or inherited traits (such as eye color) and alterations in specific genes that may impact the individual potential for a given health condition. GenomicsGenomics is the study of complex sets of genes, how they are expressed in cells (what their level of activity is), and the role they play in biology.genes
21
The Growth in Cancer Incidence and Mortality is due to: The increasing size of and the aging of the population Industrialization and adaptation of Western habits (smoking, diet, etc.) This is especially a problem in South America, Africa and Asia Growing biotechnology and development of diagnostic tests and screening technologies.

36
Prostate Cancer Screening An issue that must be approached ethically, logically and rationally We must realize: What we know. What we do not know. What we believe.
37
American Urological Association Given the uncertainty that PSA testing results in more benefit than harm, a thoughtful and broad approach to PSA is critical. Patients need to be informed of the risks and benefits of testing before it is undertaken. The risks of overdetection and overtreatment should be included in this discussion. PSA Best Practice Statement 2009
38
European Association of Urology Recommends for informed decision making within the physician-patient relationship. Recommends against mass screening. “Men should obtain information on the risks and potential benefits of screening and make an individual decision” European Urology 56(2), 2009
39
National Comprehensive Cancer Network There are advantages and disadvantages to having a PSA test, and there is no ‘right’ answer about PSA testing for everyone. Each man should make an informed decision about whether the PSA test is right for him.”
40
“Men should have an opportunity to make an informed decision with their health care provider about whether to be screened for prostate cancer, after receiving information about the uncertainties, risks, and potential benefits associated with prostate cancer screening.” The American Cancer Society 2010 Prostate Cancer Screening Guideline
41
Needs in Prostate Cancer Medicine We need: a better screening test a better way to determine the cancers that need to be watched and those that need to be treated. Then we can actually figure out how good our current treatments are!!!

Breast Cancer 765,870 cancer deaths were averted between 1991 and 2006 in women It is estimated that 57,000 humans did not die of breast cancer This was due to screening, early detection, and aggressive treatment. It is estimated screening prevalence was 45% to 50% during the period

56
Nutrition and Physical Activity Obesity, high caloric intake, and lack of physical activity has the potential of being a greater cause of cancer in the U.S. than tobacco by 2030 We are currently not able to model this in an acceptable fashion It is causing a rise in cancer incidence
