Are physicians overdiagnosing melanoma?

In an editorial in the February 1 issue of American Family Physician, Dr. Jenny Doust and colleagues wrote about the problem of widening disease clarities, a common phenomenon in which the definition of a disease is “broadened over time to include milder and earlier contingencies, ” leading to harm “by exposing more patients to the adverse effects of treatments, triggering investigation and prescribing cascades, increasing suspicion, and placing a financial onu on patients and the wider society.” Expanding the number of patients diagnosed with canker increases the burden on primary care physicians called on to manage these additional specimen, even when it is uncertain if earlier involvements thwart morbidity or mortality. Illustrative examples of wider disease clarities include hypertension, polycystic ovary ailment, breast cancer, and autism. What can attending physician do about it? The authors responded 😛 TAGENDRecognizing the problem is the first step in tackling it. In particular, family physicians should not indiscriminately countenanced new explanations and testing recommendations without an adequate understanding of the mischiefs and benefits of the changes and the implications for our patients and wider practice.

Along similar fronts, a recent analysis in the New England Journal of Medicine by Dr. H. Gilbert Welch and colleagues reviewed and considered the motorists of the dramatically increased incidence of cutaneous melanoma in the U.S ., which today is 6 hours as high-pitched as in 1975 despite virtually no change in melanoma mortality. They pointed out that exposure to ultraviolent( UV) radioactivity( including tanning bed employ) cannot account for more than a small portion of this increase. Instead, they argued that increased diagnostic investigation – “the combined effect of more screening surface evaluations, coming clinical doorsteps to biopsy pigmented lesions, and falling pathological thresholds to label the morphologic reforms as cancer” – is most likely to be responsible for the epidemic of brand-new diagnosings. Not only has the annual percentage of fee-for-service Medicare beneficiaries undergoing skin biopsies practically redoubled since 2004, but pathologists routinely upgraded scalp biopsy specimens obtained in the late 1980 s from harmless to malignant when evaluating the same specimen two decades later. Primary health care specialists contribute to widening the definition of cutaneous melanoma by playing or citing for biopsy small-time (< 6 mm ), incidentally detected skin lesions and screening cases with dermoscopy, which identifies more melanomas than visual inspection alone but is not well studied in primary care settings.

The U.S. Preventive Services Task Force( USPSTF) has concluded that current evidence is insufficient to assess the balance of benefits and injures of skin cancer screening in asymptomatic adults. Nonetheless, more than half of family physicians and general internists in a 2011 questionnaire reported playing full-body skin investigations for bark cancer screening. In a 2020 AFP editorial, Drs. Michael Pignone and Adewole Adamson( Dr. Adamson too co-authored the NEJM analysis) observed that “compared with customary maintenance, potential effects of screening on morbidity and fatality from keratinocyte carcinoma are at most small-time, and screening cannot be justified based on the impact on keratinocyte carcinoma alone.” Dr. Welch and peers went one step further, is claiming that the established harms of skin cancer screening already outweigh any potential benefits 😛 TAGENDThe increase in melanoma identifications by a factor of 6, with at least an order of magnitude more people experiencing a biopsy and no apparent aftermath on mortality, is more than enough to recommend against population-wide screening . … It[ screening] has are actually being promoted under the guise of public health, with the combination of startling words about surface cancer and the assertion that screening can only help. However, medical care should be driven by patient needs , not organization needs. Now is not the time to add more suspicion and expenditure to an already anxious and expensive world.Not amazingly, dermatologists have a more positive view of skin cancer screening, as reported in a news story about the analysis by Dr. Welch and colleagues that excerpted the president of the American Academy of Dermatology as stating that “an aggressive approach to prevention and treatment is entirely appropriate for a disease that kills 20 Americans each day.” Of course , no one is urging clinicians to stop counseling cases on understating their exposure to UV radiation; definitely, the USPSTF recommends behavioral advise to prevent skin cancer, particularly for children, their parents, and young adults. But screening for skin cancer, which has effectively enlarged the definitions contained in cutaneous melanoma and driven widespread overdiagnosis – is a different story. To return Dr. Doust and collaborators the last word: “We[ primary health care physicians] are not here to passively enact specialist recommendations. Instead, we need to more assertively act as is in favour of our patients and our communities.” ** This berth first is available on the AFP Community Blog.
