\"\"At first glance, no diagnosis seems more terrible than cancer. Although it remains a huge killer in the developed world<\/a>, cancer has also taken on new meanings in modern medicine. <\/span>As an ordinary\u00a0person, I certainly fear the word and would dread the diagnosis. Cancer<\/i>. It has such a damning and unforgiving ring to it. After 3 years of residency in a tertiary referral center, where I’ve seen some of the worst cases conceivable, I still cannot imagine the painful and devastating odyssey that those who succumb to it must endure.<\/span><\/p>\n

As a recently minted physician though, I fear cancer for other reasons. The science of the field is moving at a blistering pace.\u00a0How can\u00a0I keep up on the state-of-the-art treatments, genomic-based diagnostic tools, and molecular therapies? (When I talk about modern cancer care, I often wondering if I even talking about things that really exist.) <\/span><\/p>\n

The care of cancer patients discourages this generalist, because it has become exceedingly complicated. How do I craft my words to distinguish \u201ccancer\u201d from \u201cpre-cancer\u201d? What advice do I give to a patient with\u00a0recent biopsy-proven, localized prostate cancer? Will I be sued for negligence I didn’t offer chemoprophylaxis for breast cancer in a patient who develops metastatic disease on my watch? How can I watch expensive third-line chemotherapy being given to one of my patients while another patient eats his way to a cancer-causing BMI of 40 on a low-cost, high-carb diet? <\/span><\/p>\n

Given these questions, I thought I would begin 2014 with a reflection on what cancer means to the general practitioner.<\/span><\/p>\n

Cancer as Preventable Disease<\/b><\/span><\/p>\n

Despite all the advances we have made in diagnosing and treating cancer, we still face awesome opportunities to curtail cancer before it even starts. During the past several decades, we have clearly made strides in preventing cancer, particularly in the realm of curtailing tobacco use<\/a>. (Then again, tobacco use rates aren’t really all that different than they were 10 years ago.) And, all the while, our nation is growing increasingly obese <\/span>\u2014\u00a0so much so, that obesity threatens to overtake tobacco as the major preventable cause of cancer<\/a>. <\/span><\/p>\n

Given these trends, I sense that progress toward preventing cancer has stalled. I also wonder if enough clinicians are even considering the fact that cancer is preventable at all. When I give the lifestyle pep talk in clinic, I am usually warning patients about risks for developing cardiovascular disease or diabetes, not cancer. I also feel somewhat powerless to affect a patient’s ability to avoid cancer through lifestyle interventions.<\/span><\/p>\n

These days, we need\u00a0continued dedication to training physicians to coach patients\u00a0about lifestyle improvements. We also must bridge the divide between medical providers and our public health leaders and find more creative solutions than exploding cigarette taxes<\/a>\u00a0or rehashing ideas about food deserts, fat taxes, and junk food advertisements<\/a>.<\/span><\/p>\n

Besides preventing cancer by recommending lifestyle adjustments, the generalist must also augment his use of chemoprophylaxis when indicated. For example, even though the USPSTF reaffirmed its grade B rating for chemoprevention of breast cancer in high-risk individuals in 2013<\/a>,\u00a0most of us don’t adhere to these guidelines very stringently (NEJM JW Womens Health<\/em> Apr\u00a08 2010<\/a>), especially compared with our adherence to other grade B recommendations, like mammography. We will have even more options as aromatase inhibitors\u00a0emerge as chemoprevention<\/a>, so we generalists will need to keep up to speed in this field. Of course, we might be able to use less targeted chemopreventive techniques,\u00a0like aspirin for colorectal cancer\u00a0<\/a>and will need to know the risks and benefits of these options, too.<\/span><\/p>\n

Less Screening and More Expectant Management of Cancer<\/b><\/span><\/p>\n

Although oncologists might argue that \u201ctargeted therapy\u201d or \u201cpharmacogenomics\u201d are the buzzwords that describe the future of cancer care, my own generalist-biased ears hear \u201coverdiagnosis\u201d everywhere. Most clinicians probably think of indolent prostate cancer and the PSA debate when they hear this term, but plenty of buzz surrounds overdiagnosis for other reasons. <\/span>Part of the issue is the desire to redefine clinical entities that have often come with the bleak label of \u201ccancer.\u201d For example, the debate over DCIS has shifted from how to treat it to how we even describe it to patients<\/a>. And, clearly, what we call DCIS does matter.<\/span><\/p>\n

We also have new screening modalities that have generated excitement, such as the USPSTF and American Cancer Society’s endorsement of low-dose chest CT for lung cancer. Clinicians must remain circumspect about use of this screening tool though, as chest CT itself can reveal countless false positives and also carries serious risk for overdiagnosis<\/a>. And, like the PSA\/prostate cancer debate I’ve seen unfold over my training career, low-dose chest CT can lead to expensive, debilitating, and potentially deadly complications from biopsies and excessive cancer treatment.<\/span><\/p>\n

All of this talk of overdiagnosis also makes me wonder where the medical community will draw the line on whom to screen. I wonder how willing the public will be to accept expectant management as a treatment option. The American Cancer Society\u00a0already has published patient information for managing prostate cancer expectantly<\/a><\/span>, but how often will patients with something more deadly \u2014 say, lung cancer \u2014 opt for \u201cjust watching it\u201d?<\/span><\/p>\n

Cancer at the Crux of the Medical Economics Arguments<\/b><\/span><\/p>\n

Finally, all of these cancer-related issues are bound to intersect at the most timely of all topics in medicine: cost-effective care<\/a>. That cancer care is extremely expensive is no secret. Thus, we will need to be more selective in our use of cancer treatment modalities. Will our payers begin to curb use of treatment modalities that do not confer a defined benefit for their cost, such as radiotherapy for prostate cancer<\/a>? <\/span>And on the question of cost-effective screening, will we continue to find more cost-effective ways to identify cancer early (like HPV testing every 5 years for detecting cervical cancer<\/a>)? <\/span><\/p>\n

Cancer 2014<\/span><\/b><\/p>\n

Cancer is no longer the ultimate evil that must be detected early and destroyed at all costs. I don’t know that it ever was, but I do know that decision-making around prevention, detection, and treatment of cancer has become more nuanced than ever before.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
