Anal Cancer - Should I be concerned?
May 18, 2010
Nelson, I know you are a long term survivor. What have you done to make sure you do not have anal cancer? I am so afraid of it since I read we have like 10 times the rate.
Response from Mr. Vergel
Like you, i am also very concerned about anal cancer since I have been living with HIV for over 25 years.
In the United States, the rate for anal cancer in the general population is 1 case per 100,000 people; among HIV-negative men who have sex with men the rate increases to 35 cases per 100,000 people.
But in HIV-positive gay and bisexual men the rate is estimated to be between 75 to 115 cases per 100,000 people.
There have been barriers to diagnosing anal cancer. People do not usually tell their doctors about anal issues, and many doctors do not check their patients' butts in physical exams (not even to do digital prostate exams!).
Anal cancer is caused by the HPV virus, to which most of us have been exposed. It seems to affect those of us who have lived longer with HIV, have had detectable HIV viral load for a few years, have had anal warts (debatable) and/or had lower CD4 cells in our HIV infection.
There are really no guidelines yet about how to test or diagnose anal cancer. The University of California in San Francisco is leading the way in studying different methods of detection. They are researching three forms of tests: an anal Pap smear (where the doctor swabs an area of the anus to remove surface cells), an anoscopy (where a doctor uses a special microscope to look at the anus), and a biopsy (where the doctor scrapes away an area of the anus to remove surface cells).
Preliminary results showed that anal Pap smears accurately detected pre-cancerous skin cells about 70% of the time. The higher the grade of disease, the more likely Pap smears could detect these skin cells. They were also more accurate when there were more pre-cancerous cells present. Anal Pap smears were also better able to find disease in HIV-positive than HIV-negative people (76% vs. 59%). In addition, anal Pap smears were more likely to find disease when CD4s were below 400, and when two or more areas were swabbed for cells (86%) as opposed to one or more (69%). So, using anal Pap smears still leaves room for errors.
I have been getting high resolution anoscopies every two years or so n the past 6 years. Cancerous cells are very difficult to see with a naked eye, so doctors spray vinegar in your rectum and shine infrared light in it. Cancerous cells shine differently than healthy cells, so doctors are able to distinguish them in the presence of vinegar and the light. Very few doctors are trained in that procedure (UCSF trains doctors in a 2 day program). My first anoscopy showed precancerous lesions which were removed by infrared coagulation.
My insurance has paid for most of the procedure and the biopsies required.
Below is the list of providers changed in HRA from the currently offline UCSF Anal Cancer Info website. I've been asked to post this with the caveat that it is not up-do-date, but does include providers who have been trained in HRA by UCSF. They are working to get their website back up ASAP (The stae of California is beset by budget cuts and staff layoff/furloughs, so nothing is happening quickly) In the meantime, CATIE has a great anal dysplasia info sheet with good basic info

Hopefully, we will have national guidelines on this issue within the next 5 years when studies proof that early diagnosis make a difference. But may patients like me are not waiting for that to happen.
I hope this helps!
