Cancer Cases

In the December 8th issue of the New England Journal of Medicine in the Perspective section, there appears an article, “Making Sense of the New Cervical Cancer Screening Guidelines,” by Dr. S. Feldman.  Dr. Feldman concedes that Pap smear sensitivity is poor, “roughly 50 to 60% [false negative].  She does not in her article explain the relatively poor sensitivity of the test but we can learn easily from other literature that a major contribution to the poor sensitivity of the test relates to improperly identified or interpreted smears.

 

While it is true that multiplying the frequency of smears increases the likelihood in spite of negligent readings that a cervical abnormality will be discovered while the disease is pre-invasive.  There is no study randomized and prospective which proves that.  Someone has simply picked out of a hat a frequency that they think is greater than needed and a frequency that is somehow lesser than needed and it comes to kind of a consensus that after age 21 every three years is frequent enough.

 

Cervical cancer is a very aggressive disease particularly in women who acquire the disease in their 30’s and 40’s.  No intelligent woman knowing she possessed a cervical abnormality would decide to wait three years to do something about it.  Where therefore does the pressure come from to reduce the frequency of looking?  Most women considered healthy to have their gynecologist see them annually and Pap smears are done at this annual exam.  Pap smears are relatively inexpensive.  Of course, even something that is inexpensive becomes expensive when you multiply it by 100,000,000.

 

On the other hand, if a lab is getting $25.00 to $30.00 for every Pap smear it screens and requires the cytotechnologists (not doctors)  who read the slides to read as many as 100 a day, one can see readily where the money is going.

 

I recently questioned during a deposition a cytotechnologist who had screened a slide with obvious severe abnormalities on it which she had in fact marked with screening dots.  She doesn’t know why she put the slide back in the box but she did.  She was having difficult times in her personal life which she had shared with her supervisors and others at the organization that was requiring her to perform as many as 96 screenings a day in spite of her obvious distraction.

 

While 4,000 to 5,000 women are needlessly dying of cervical cancer in the United States every year, cost efficiency is truly in the mind of the beholder.

 

In her article Dr. Feldman goes on to assert that HPV testing done with Pap smears, though recommended by the American Cancer Society every three years, is not recommended by anyone else including the United States Preventative Services Task Force.

 

It is well-know that women who are HPV positive are at much higher risk of developing cervical cancer in women who do not have this characteristic.  It is also well recognized that any sexual encounter with a new person, particularly if it is unprotected sex could result in the transmission of HPV.  Therefore, the fact that a person in a committed relationship is negative for ten years doesn’t mean that they are going to be negative for the next ten.

 

I keep on writing about this even though few hear what I have to say.  It is simply that I am tired of watching my clients die of cervical cancer that was preventable if a person had been allowed to spend more than eight minutes reviewing their slide or were willing to endure the further expense of subjecting the slide to HPV testing.  I wonder which committee of government or the prestigious professional organizations that direct these policies think they are in a position to decide what a woman’s life is worth.  Perhaps if they watched more women die of cervical cancer as has been my unfortunate experience, they would find that testing every year rather than every three and adding HPV testing is cost efficient.

See No Evil-Speak No Evil

by Jerry Meyers on January 4, 2010

January 1, 2010 Journal Watch summarizes a remarkable article entitled “Investigation of incidental findings on cardiac CT.”  The article was based on a study conducted at a Canadian institution where the investigators evaluated the incidence, clinical importance, and costs of these incidental findings.

It’s first important to note that these researchers used the word incidental as  equivalent to the word, occult.  In medical imaging, an occult finding is an unexpected finding that has clinical consequence.  Such findings are made with great frequency and have dramatically improved the lives of many.  For example, a chest x-ray searching for a rib fracture reveals a lung cancer mass which was otherwise completely unexpected.  A CT scan of the abdomen performed because of a complaint abdominal pain reveals a dissection of the thoracic aorta.

The Canadian researchers are strangely troubled by the discovery of   unexpected conditions.  The test they are evaluating is cardiac CT.  Imaging data obtained during a cardiac CT includes imaging information of structures or tissues outside the heart.  in an examination of 966 consecutive patients who underwent cardiac CT during 12 months at a single Canadian institution, incidental findings were noted in 401 patients.  12 of the patients were found to have clinically significant conditions, many of them, life-threatening without treatment.

Even if one accepts the very conservative assessment that only 12 of the patients were found to have clinically significant conditions,  that means that 3% of everyone who had a cardiac CT performed had a condition that might have seriously harmed or killed them if it had not been accidentally seen in this study.

The researchers do not see the benefit derived by the 3% as a bonus.  They don’t question that all the patients benefited from having a cardiac CT.  In fact, no one questions that this method of scanning provides an important and noninvasive method of evaluating patients suffering coronary calcification and arterial disease.  However, 68 patients exhibited incidental findings such as nodules or cysts in the lungs or liver.  There’s the rub.

Confronted with 68 patients of the 401 who had abnormalities deemed to be indeterminate (undetermined significance)  researchers worry that the abnormalities found might lead some to conduct further testing or evaluation.  The solution, as they see it, is to not format the data concerning non-cardiac tissue and structures.  They want to ask patients to consent to keeping the non-cardiac information invisible.  If they see no “evil”, they need speak no “evil.”

I think this is insanity. What do you think?

The Pap Smear – Not Too Many – Too Few

November 20, 2009

According to the American Cancer Society’s most recent estimate for 2009, 11,270 new cases of invasive cervical cancer will be diagnosed and 4,070 women will die from the disease. Prior to 1955 cervical cancer was one of the most common causes of cancer death for American women. As a result of the development of the [...]

U.S. Preventative Services Task Force on Routine Screening With Mammograms for Breast Cancer

November 20, 2009

November 16, 2009 the Washington Post reports new screening guideline issued by the U.S. Preventative Services Task Force now recommending against women receiving routine screening with mammograms for breast cancer prior to age 50. Petitti, Chairman of the Task Force, asserts that the new recommendation will result in “just” 0.7 deaths for every thousand women [...]

Gardasil, a Good Idea?

October 30, 2009

Gardasil is a HPV vaccine produced by Merck.  HPV, Human Papilloma Virus, has clearly been demonstrated to increase the risk of a woman developing cervical cancer so it would seem to be a good idea to provide young woman, even as teenagers, with a vaccine that would guard against the virus and prevent the development [...]

The Electronic Medical Record-Better Medicine?

July 16, 2009

In a previous post I briefly discussed how communication failures in the transmission of test results are common.  Many people think that widespread use of electronic medical records systems throughout all of our health systems will improve medical care. You cannot improve a physician’s standard of practice simply by altering the means by which records [...]

Cancer Misdiagnosed in 12% of Cases: Study by Alan Mozes

March 11, 2009

According to Alan Mozes’ report, Monday October 10 in Health Day Reporter, a new study suggests more than 12 percent of cancer patients in the U.S. are undiagnosed initially. Apparently this leads to treatment delays and lost opportunities for better outcomes. The study was conducted by a team of researchers from Canada, China and the [...]
