HPV: a virus that can cause cancer

In 2006, the quadrivalent human papillomavirus (HPV) vaccine was authorized in Canada for use in females between the ages of 9 and 26 years for the prevention of infection caused by HPV types 6, 11, 16 and 18. Types 16 and 18 are most common cause of  cervical cancer. They can also cause vulvar, vaginal and anal cancers. Types 6 and 11 are most common cause of genital warts.

In Feb. 2010, the vaccine was approved for use in boys between ages 9 and 26. The vaccine was found to decrease the odds of genital warts. Since males are usually a silent carrier of the virus, vaccinating boys is thought to decrease the incidence of cervical cancer in females by decreasing transmission.

In April 2011, the quadrivalent vaccine was approved for use in females up to age 45. A new indication for prevention of anal cancer was also added.

The quadrivalent vaccine is now the standard of care. It has been recommended by the National Advisory Committee on Immunization (NACI) for use in womyn ages 9 to 45 for prevention of cervical cancer and anogenital warts, and in men ages 9 to 25 for prevention of anal cancer and anogenital warts. NACI also recommends the vaccine to men who have sex with men (MSM) from the age of 9 onwards. Stronger evidence was found for the quadrivalent vaccine (Gardasil) as compared to the bivalent vaccine (Cervarix).

This vaccine decreases the risk of cancer in men and womyn. It is essential to make it available and accessible. With all the strong evidence that is now available for the benefits of such vaccination, it becomes unethical to withhold such intervention. Having said that, vaccination alone is not enough. We should continue to raise awareness about practices that reduce the risk of transmission of this and other sexually transmitted viruses, like abstinence and monogamy whenever feasible, condom use (limited role with HPV transmission) and targeting marginalized groups like sexual minorities (lesbian, gay, bisexual and transgendered LGBT) underprivileged and uninsured, among others.

I just got my Flu Shot today. You should too, especially if pregnant.

It is NOT “just the flu”. When you are pregnant influenza virus can have serious implications on your health and the health of your baby. The best treatment is prevention.

If you are pregnant or recently delivered a baby, I strongly advise you to get vaccinated against seasonal influenza.

The flu vaccine was proven to be safe and effective. It has been given to millions of pregnant women over the past decade and has NOT been shown to cause serious harm to women or their babies.

As an added bonus, vaccination during pregnancy will pass on immunity, protecting your baby until she/he is old enough to receive her/his own vaccinations. Remember, your newborn baby can not receive the flu vaccine before she/he is 6 months old.

You can receive the flu vaccine in any trimester and after you deliver even if you are breast feeding.

You should NOT receive the vaccine if you are sick with a fever or if you are allergic to eggs.

If your care provider does not offer the vaccine, make sure she or he refers you to someone who does.

I understand you took it last year. You do need it again:

Influenza virus has many types. Each year the flu vaccine is designed to prevent the most commonly circulating types. The vaccine changes every year. So even if you received the vaccine last year, you still need to be vaccinated with this year’s vaccine for best protection.

DO NOT take the nasal spray vaccine during pregnancy:

There are two forms of the vaccine. One is given as a shot in your muscles (flu shot: contains inactivated virus) and the other as spray in your nose (nasal spray: contains live virus). After you deliver either form of the vaccine is appropriate.

5 Reasons why you should receive the vaccine:

  1. To protect yourself. Influenza is more likely to cause severe illness, even death, when you are pregnant as compared to when you are not.
  2. To decrease your chances of having preterm labor or delivering a premature baby if you catch the flu
  3. To offer protection to your new born baby during the first 6 months of her/his life. During this period, your newborn baby is 10 times more likely to be hospitalized if she/he catches the flu.
  4. Severe illness in postpartum women was also documented. Last year’s H1N1 (Swine flu) is expected to circulate this influenza season so it is included in the seasonal trivalent influenza vaccine this year.
  5. By not catching the flu you help avoid communicating the infection to other people and family around you

 

“But isn’t it controversial?”

No, it is not controversial. It is strongly recommended by all of the following medical organizations in a joint statement released on Sept. 15th 2010:

Here is my mom’s reaction to my persistent requests for a PAP test (فحص المسح المهبلي او فحص القزازة): “I am not comfortable on the exam table with that thing shoved down there.” Well, who is? I would start to worry if she actually liked it!

Two years ago, I gave a seminar about sexually transmissible infections to a group of women belonging to human rights organization in Beirut. Their awareness about HIV, Chlamydia, Gonorrhea, Herpes and the other culprits was optimal. Little did they know about HPV. Eyebrows were raised when I spoke about how common it is, how easily transmissible and how it can cause cervical cancer.

Social media campaigns in Lebanon have tackled breast cancer, diabetes and other diseases. Little has been done to raise awareness about the Human Papilloma Virus or HPV (فيروس الورم الحليمي البشري) and cancer of the cervix (سرطان عنق الرحم), options for early detection and prevention.

The Lebanese Ministry of Health website has awareness campaigns for Breast cancer, diabetes and Hepatitis, prevention campaigns for smoking and HIV, surveillance sections for different infections and cancers. A search for HPV returns 0 results. Even on a page dedicated for vaccination, there is no mention of the cervical cancer vaccine.

So why is HPV awareness suboptimal in Lebanon?


No research has addressed this issue and I do not claim to have the answers. I welcome your feedback and comments. Feel free to add theories that you believe might be a factor. Here are few that I could think of:

Is it lack of interest by the medical field in Lebanon?

Very little research is done on HPV disease in Lebanon. A quick PubMed search using “HPV” and “Lebanon” brings up only a handful of articles. The questions remains: Why is there lack of interest?

Is it lack of interest by pharmaceutical companies?

Unfortunately, most of the current health awareness campaigns in Lebanon, like anywhere in the world, can be driven by pharmaceutical and medical equipment companies. Does cervical cancer sell less? Will having the new vaccines on board change that?

Is HPV less prevalent in Lebanon as compared to western countries?

A study by Dr. Adnan Mroueh published in 2002 showed that up to 5% of Lebanese women between ages 18 to 76 carry the virus. This is similar to Arab countries but significantly less western countries (40 – 60%). This might be a valid reason. However, the study by Mroueh tested for only few types of HPV which might explain the low prevalence.

Is it the social taboo of sexuality?

HPV is sexually transmitted and many would like to believe or claim that extramarital or premarital sexuality do not exist in Lebanese communities. In October 2007, Al-Akhbar publishes “Who remains silent about HPV disease is a mute devil” or “H.P.V: الساكت عن المرض شيطان أخرس”. This very interesting and rare article in the Lebanese media addresses the lack of awareness and invites people to discuss HPV and cervical cancer more openly. It includes true stories of how societal prejudice can ostracize some Lebanese womyn diagnosed with HPV.

HPV vs HIV media attention

"Media attention to HIV vs. HPV"

Is it the social fear from and ignorance about cancer?

The further you go away from Beirut and big cities the weirder the alternative names for cancer get. You reach my village and there they call it “The Evil Disease” or “المرض الخبيث” and “The one whose name we shall not say” or “هيدا يلي ما بيتسمى”. But then why breast cancer awareness is at its peak?

Is cervical cancer less disfiguring to “female prototype”?

I feel appalled by even typing that. You might feel it is a remote possibility especially if you are not familiar with the Lebanese societal dynamics. Before you proceed here are two facts about Lebanon:

  1. Lebanese banks offer plastic surgery loans. Read “Nip’n'tuck loans offer in Lebanon” by BBC news. AFP took it a step further and described the situation as ‘a national duty for women to look the best‘ in their article “Sea, sun and scalpel.”
  2. Lebanon tops the world’s charts for plastic surgeries performed per capita. “Official estimates place the number of cosmetic surgeries carried out annually in the country at 1.5 million”.

Here is an eye-opening perspective from a Lebanese woman who wrote “HPV: Is it Really Worth the Shot?” for Bekhsoos, the queer arab online magazine. She writes: “I for one refuse for health workers to tell me that my breasts are much more important than my uterus. Both forms of cancer are dangerous and can lead to death, yes…. However one can be prevented but is associated with sexual conduct and therefore isn’t accepted. While the other deals with aesthetics- and therefore gains more sympathy.”

Lebanon has a Chauvinistic framework but could it be that bad? Does she make a valid point?

Food for the thought,

Two weeks ago, a nice young woman presented to my office for excessive vaginal discharge that she had for the past year. The moment I saw her cervix, I knew what I was looking at: Cancer. Her last gynecological exam was 5 years ago.

Who is to blame? Is it the responsibility of the patient, the physician or the health care system? With all the recent advancements in cancer prevention and early detection, it becomes unacceptable to allow any woman to develop cervical cancer. We are all responsible.

Breaking cancer news to my patients and their families is the second least favorite part of my job. We have the means to put an end to cervical cancer. We should raise awareness about this cancer and its causes, more so in less developed countries. My next post will be about cervical cancer awareness and barriers encountered in Lebanon.

Can a virus cause cancer?

Human Papillomavirus or HPV is the most common sexually transmissible infection. It is the leading cause of cancer of the cervix. HPV can also cause cancer of the vagina, vulva, penis and anus. There are more than 100 different types of HPV. Low risk types like 6 and 11 usually cause warts. High risk types like 16 and 18 are responsible for 75% of cervical cancer cases. Generally, men and womyn are silent carriers. They will carry and transmit the virus without having any symptoms at all.

There are no medications to treat the virus. It takes months to years for your immune system to defeat it. Cigarette smoking, high risk sexual behavior and having multiple sexual partners are among factors that might make the progression to cancer faster.

Is my partner unfaithful?!

If you are in a long-term monogamous relationship and were recently diagnosed with HPV, do not jump to conclusions about the faithfulness of your partner. Attempts to know who gave it to the other are futile. I tell my patients that there is no need to start using condoms or dental dams for the sole reason of preventing transmission of the virus to your monogamous partner. He or she likely has the same HPV types already.

Now, it is not all gloomy! Here is the bright side. For womyn, a vaccine can prevent HPV infection and a PAP test can detect early cancer allowing complete cure.

Yes, we can prevent HPV infection!

Condoms do not offer full protection. HPV transmission can occur by skin-to-skin contact. The good news is that you can now be vaccinated against HPV.

Two HPV vaccines are available:

  • Gardasil (By Merck & Co, Inc.): Quadrivalent HPV vaccine (protects against 4 types of HPV: 6, 11,16 and 18). It was FDA approved in 2006 for use in females aged 9 through 26 years.
  • Cervarix (By GlaxoSmithKline): Bivalent HPV vaccine (protects against 2 types of HPV: 16 and 18). It was FDA approved in October 2009 for use in females aged 10 through 25 years.

The vaccine is given in three-dose series. Get in now. Your second shot will be in 2 months and the third in 6 months.

In addition to preventing cancer, the vaccine also lowers your chances of developing genital warts, which can be as psychologically burdening.

The vaccine works best when given to individuals who have never been sexually active. Nevertheless, there is still a proven benefit even if you are sexually active and had HPV or precancerous cells on your PAP test. The vaccine might prevent re-infection or re-activation of the virus.

Yes, we can detect cancer early (even before it happens)!

The Pap test has significantly lowered the incidence of cervical cancer among womyn. Cells are taken from the cervix and examined. If abnormal, your provider might ask you to have a colposcopy. With colposcopy, the vagina and cervix are washed with acetic acid or vinegar. A light and magnifying lens allow your doctor to visualize and biopsy any abnormal tissue. If early cancer or precancerous cells are confirmed after biopsy, your doctor can burn, freeze, laser or cut out the affected part of the cervix, thus slowing or arresting the progression to cancer.

So if you are between ages 21 and 29, you should get a PAP test every 2 years, then every 3 years once older than 30 according to the most recent guidelines by the American College of Obstetricians and Gynecologists. If, however, you have high risk factors or previous abnormal PAPs then you might need more frequent PAP tests. Always discuss with your doctor.

What lies ahead! Recent research, future approaches

Vaccinate the boys!

On October 16th, 2009, the FDA approved use of Gardasil for the prevention of genital warts (condyloma acuminata) due to HPV types 6 and 11 in boys and men, ages 9 through 26.

In July 2010, the 26th International Papillomavirus Conference in Montreal, Canada addressed the importance of the recent shift towards a “gender-neutral” vaccination policy. The conference discussed the significant decline in HPV-related disease in men and womyn after the Australian national HPV vaccination campaign was introduced in mid-2007.

Anal “colposcopy” for womyn!

The September 2010 issue of the Green Journal (Obstetrics & Gynecology) published a study that suggested screening for anal cancer (Anoscopy) all womyn with pre-cancerous cells in the cervix, vagina or vulva. I agree with Dr. Linda Eckert: “We are not ready for such recommendation” she wrote in Editorials of the same issue. More research is needed to support such guidelines.

Anal PAP test for men!

In Sept. 2010, the 28th Annual Conference of the Gay and Lesbian Medical Association (GLMA) in San Diego, USA took the discussion one step further. There were four plenary and breakout sessions on anal dysplasia and cancer, anal PAP test, and HPV vaccination in men. Even though recommendations for anal PAP testing have not been endorsed widely by medical organizations, few centers in USA have developed the experience in performing and reading anal PAP tests. The results are promising, but again, much more research is needed in this field.

Vaccinate womyn older than 26!

If you are between ages 26 and 45, you might be a candidate for the vaccine. Discuss it with your doctor. A large well-designed study published in the Lancet in 2009 showed favorable results for HPV vaccination in womyn ages 24 to 45. No recommendations for this age group have been made yet.

Can we do better?

It appears that we should do a better job at vaccinating. Over the three years since Gardasil was approved, only 18% of adolescent females have received all 3 doses. Many marginalized group of womyn do not receive adequate PAP testing.

It is unjust for a woman anywhere in the world not to benefit from the available means to fight cervical cancer.

We need to raise awareness.

We should aim at eradicating HPV like we eradicated small pox in 1977.

We should make HPV-related cancers history.

You should help propagate this info.
