Are physicians overdiagnosing melanoma?

In an editorial in the February 1 issue of American Family Physician, Dr. Jenny Doust and peers wrote about the problem of dilating cancer interpretations, a common phenomenon in which the definition of a disease is “broadened over time to include milder and earlier occurrences, ” leading to harm “by exposing more patients to the adverse impacts of medicines, triggering investigation and prescribing cascades, increasing distres, and placing a fiscal headache on patients and the wider society.” Expanding the number of patients diagnosed with canker increases the burden on primary care specialists called on to manage these added instances, even when it is uncertain if earlier interventions avoid morbidity or mortality. Illustrative examples of wider disease clarities include hypertension, polycystic ovary syndrome, breast cancer, and autism. What can attending physician do about it? The writers responded 😛 TAGENDRecognizing the problem is the first step in tackling it. In special, family physicians should not indiscriminately professed brand-new definitions and testing recommendations without an adequate understanding of the distress and benefits of the changes and the implications for our patients and wider practice.

Along similar wrinkles, a recent analysis in the New England Journal of Medicine by Dr. H. Gilbert Welch and colleagues examined the moves of the dramatically increased incidence of cutaneous melanoma in the U.S ., which today is 6 hours as high-pitched as in 1975 despite essentially no change in melanoma mortality. They pointed out that exposure to ultraviolent( UV) radioactivity( including tanning bed application) cannot account for more than a small portion of this rise. Instead, they argued that increased diagnostic inquiry – “the combined effect of more screening bark reviews, descending clinical thresholds to biopsy pigmented lesions, and descending pathological doorsteps to label the morphologic varies as cancer” – is most likely to be responsible for the epidemic of brand-new identifications. Not only has the annual percentage of fee-for-service Medicare beneficiaries undergoing skin biopsies practically doubled since 2004, but pathologists frequently ameliorated skin biopsy specimen obtained in the late 1980 s from benign to malevolent when evaluating the same specimen two decades later. Primary health care specialists contribute to widening the definition of cutaneous melanoma by performing or referring for biopsy big (< 6 mm ), incidentally spotcheck surface 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 Assistances Task Force( USPSTF) has concluded that current evidence is insufficient to assess the balance of benefits and injures of surface cancer screening in asymptomatic adults. Nonetheless, more than half of family physicians and general internists in a 2011 investigation reported performing full-body skin examinations for skin cancer screening. In a 2020 AFP editorial, Drs. Michael Pignone and Adewole Adamson( Dr. Adamson also co-authored the NEJM analysis) observed that “compared with customary care, potential effects of screening on morbidity and fatality from keratinocyte carcinoma are at most big, and screening cannot be justified based on the impact on keratinocyte carcinoma alone.” Dr. Welch and peers went one step further, arguing that the established harms of skin cancer screening once outweigh any potential benefits 😛 TAGENDThe increase in melanoma identifications by a factor of 6, with at least an order of magnitude more parties undergoing a biopsy and no seeming accomplish on death, is more than enough to recommend against population-wide screening . … It[ screening] has been effectively promoted under the guise of public health, with the combined effects of fearing letters about scalp 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 tension and overhead to an once anxious and expensive world.Not surprisingly, dermatologists have a more positive view of scalp cancer screening, as reported in a news story about the analysis by Dr. Welch and collaborators that repeated the president of the American Academy of Dermatology as stating that “an vigorous approaching to prevention and treatment is entirely appropriate for a disease that kills 20 Americans each day.” Of route , no one is urging clinicians to stop counseling cases on belittling 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 surface cancer, which can actually increased the definition of cutaneous melanoma and driven widespread overdiagnosis – is a different story. To apply Dr. Doust and peers the last word: “We[ primary health care specialists] are not here to passively enact specialist recommendations. Instead, it is essential to more assertively act as advocates for our patients and our communities.” ** This post first is available on the AFP Community Blog.
