Studies Show Anti-TNF Drugs Don’t Raise Cancer Risk

Two new studies back up previous research and found no link between an increased risk of cancer and anti-TNFs.

By Tammy Worth

6/30/11 Two new studies have found no link between an increased risk of cancer and tumor necrosis factor-alpha inhibitors, or anti-TNFs, a type of biologic drug.

Biologics, including anti-TNFs, work by interfering with parts of the immune system to decrease inflammation, a central feature of rheumatoid arthritis, or RA. Because of this, there has been concern that anti-TNFs and other biologics may increase patients’ cancer risk as well as their risk for serious infections.

In the first study, a meta-analysis published in the June 2011 Arthritis & Rheumatism, researchers reviewed six trials that included a total of 2,183 RA patients taking anti-TNFs and 1,236 taking methotrexate. The patients all had early-stage RA and had not been previously treated with methotrexate or other disease-modifying anti-rheumatic drugs, or DMARDs. The duration of the trials were between six and 12 months.

The analysis found that 19 people taking at least one dose of an anti-TNF, including adalimumab, or Humira; etanercept, or Enbrel; and infliximab, or Remicade, developed a malignancy compared with 10 patients taking methotrexate. Researchers concluded there was no significant difference in risk.

The second study, presented in May at the 2011 European League Against Rheumatism conference in London, looked at more than 13,600 Danish patients, the majority of whom had RA, from the DANBIO registry, a nationwide database that includes all rheumatic patients receiving biological drugs. From January 2000 to the end of 2008, almost 5,600 of them had started anti-TNF treatment.

The researchers cross-referenced data from DANBIO registry with the Danish Cancer Registry and found that 181 patients ever treated with an anti-TNF developed cancer compared to 132 patients who had not taken an anti-TNF. The researchers concluded there was no statistical difference in cancer risk. After further analyzing the data, the researchers also concluded that the risk of cancer did not rise with longer-term use of anti-TNFs.

“This is a reassuring reinforcement of previous data,” says Daniel Furst, MD, professor of rheumatology at University of California, Los Angeles.

Research from 2006 in the Journal of the American Medical Association found the likelihood of malignancies was greater in people taking higher doses of anti-TNF medications than those receiving lower doses.

I am a 43 year old women recently put on Humira for seronegative arthritis, which is another branch on the RA tree. With this type of arthritis your bloodwork all comes back negative, but your joints show the same wear and tear as regular RA. I have suffered for years and always told that the only reason I hurt was because of my weight. I was born with a club foot and have had 9 reconstructive surgeries. I have been on Methotrexate, Plaquenil, Folic Acid and Prednisone for the past two years since my diagnosis and recently suffered a set back because I started to go into liver failure. That's when my doctor decided to try the Humira every 10 days. It worked a miracle for me. I was actually able to get out of bed by myself for the 1st time in years. I recently had to go without 2 injections because I was having some dental surgery done and I'll just say I never want to have to go through that again. In my opinion on a personal and professional basis, as a pharmacist, it is a risk that I am willing to take. I will leave it up to the individual person to decide for themselves, but if you have dealt with what I have had to deal with at least be willing to take a chance and see if it helps to improve your quality of life as much mine.

I was diagnosed w/ RA 8 years ago @ the age of 45. I have been on a combination of Enbrel and methotrexate,folic acid, Oscal 500D and Women's One a Day vitamin.
I, like Janet feel that my current Quality of Life is most important. I would rather use prayer and faith in God who I strongly feel can change the risk factor challenge.
I am a school teacher and love my the calling God has placed on life to help others. I love volunteering as a Girl Scout leader and helping to distribute food during the summer at the local Outreach Center. I love being the Christian Education Dtr and Sunday School teacher in my church. And last but not least I enjoying the time I have with my children and grandchildren and extended family. Bible study is how I begin my day. My desire is to live one day at a time with the use of my all of my limbs. I am able to do this with God and grateful that the Enbrel and methotrexate has stopped the progression of joint damage. I exercise, watch my diet that may cause inflammation, drink plenty of water which helps decrease the side effects, and for pain I pray. (It works, the power of prayer does work.) I refuse to take more medicine.

My daughter (4 1/2 yrs old) takes kineret (anakinra). She has gotten the injection since 21 months old. It seems to work great for her, but long term effects scare me. Anyone else take this and notice any positive/negative effects??

I am in my early 60s, with diagnosed RA since I was in my early 20s. I have been on mega doses of aspirin, NSAIDs, gold shots, plaquenil, MTX, remicade, orencia, enbrel, you name it and I have probably taken it. I read the happy results of taking TNF blockers and I have to give a different perspective on them.

Cancer is in the tiny side-effects lettering on many of these drugs, and you can accept this as necessary for the improvement in your arthritis UNTIL you get cancer (which I did in 5/09), UNTIL your life is turned upside down by it and by chemo (5/09 to 12/09) and by ultimately having to face your own mortality a little earlier than you planned.

I will not take TNF blockers again. I have reverted to MTX which I tolerated well, and some natural alternatives. I think this is an option you will not hear often from any rheumatologist but it IS an option. Consider it.

Hey Jo,
Like you, my hair is dry so I do not need to wash it frequently. Yes, you can apply the Nioxin Scalp Therapy to any areas where you want to re-grow hair. Give it time and you will be back on this website telling others! Good luck!

Being 75, I onlly wash my hair weekly. Do you think the Nioxin recommended for hair loss would still be effective with only weekly use? I do take my share of meds which might be a factor,and the hair loss is mostlyl all around the front, so its harder to hide. Pardon my vanity but I'd love it to thicken up some.

This is a message for Heather and all others who have experienced hair loss due to medications. My hair loss came from the drug Orencia. I had success with a product called Nioxin Scalp Therapy. It is available at most beauty supply shops and many salons. It is not expensive. You apply it to the scalp only after a shampoo, leave it on for a few minutes, then rinse. It revitalizes the hair folicles, and you start seeing tiny hairs coming in. It works for the guys too. Good luck!

To Heather trying to cope with hair loss. Many years ago I asked my doctor to prescribe injectable folic acid (a B vitamin) so that I could give myself shots. The Methotrexate is a folic acid antagonist. You can take folic acid pills, but they may not be well absorbed if you are over forty. The usual dose is 1 mg., or 1,000 mcg, since folic acid pills come in mcg's.

Hello there. I just turned 30 and for my birthday had a confirmed diagnosis of RA. There had been some question of Lyme because of a bite I had recd. in 2009. We don't know what bit me. I have since had numerous blood tests and a recent synovial tissue biopsy to determine any sign of Lyme.
I do know that I have been on both Mtx and prednisone treatments that did not help. Then Cimzia was added to my treatments. The prednisone just made me hyper and not able to sleep. I was showing no signs of improvement. Then I went on a series of Antibiotic treatments for over a month. I will say that I noticed some help with them but then the moment I went off of them to retest, I excelled downhill very quickly and became worse than ever. My primary joints affected have been my left knee and my neck. Not your typical RA.
With my recent test results showing no sign of Lyme or any fungus/infection, I have been placed on Embrel, Plaquinil, and a very low dose of Prednisone. It has been night and day for me. I have my life back for the most part. I recently had to cut out my Embrel because of a cold that I had developed. I could notice a difference in my pain after just missing 2 weeks of Embrel. I am not trying to sell this drug as I hate the fact that I have to take drugs to live, I am just saying that whatever the case may be, I have had so much relief.
My goals are to be able to get back to doing Yoga regularly while comfortable and to get off of Prednisone all together.
As far as TNF's and Cancer, with all of the research that I have done on my own, I have found that inflamation in itself can increase your risks for developing Cancers. That is why it is so important to get the inflamation and the causes for inflamation under control. I know that everyone in my family that has passed away has passed from some type of Cancer. I look at life that I may develop it either way. I know that I have a 3 year old baby girl who I need to be able to take care of and enjoy right now! I am continuing to try to make diet changes in cutting out those inflamatory culprits and I am going to continue with omegas. and always move, that is key.
We could pass away at any moment from anything, just live everyday as you have it and enjoy every second.
God Bless

at 39 I had signs and did not know I had RA, all the pain went into remission after the summer of he**!!! Then at 49 it came back I went to a DR. & was diagnosed with RA. I am 54 now have had prednisone and methotrexate and appx. 2 year ago started with humira. It was like night and day. I have had so much relief and it is the best for me. So now I take 6 methotrexate pills every sunday and every two weeks humira (pen style injection) and only if I need do I take celebrex, and this is so rare when I do! Thanks to these type drugs I am doing very very well and really so far so good!

I am 69 and have had RA for over 30yrs so Enbrel was too late to stop any damage but although I'm pretty crippled from it, it's almost completely stopped any pain! I've already had over 30 joint related surgeries and all major joints have been replaced. I have have 4 or 5 more to look "forward" to!

The new drug company I was required to switch to last year told me there was supplemental help thru the Enbrel Liven Program. I believe you can find their phone number on line. Since I've contacted them a year+ ago they have helped me so much that I find it hard to believe. The fist 6 months they paid my entire co-pay, the next 6 I only paid $10.00 & they covered the rest. Now they've switched me to a different program which is paying the entire co-pay again. I don't know how long this will last.

I don't know why our MD's don't tell us about this. I don't really know what the requirements are to qualify but I have Medicare & a Blue Cross Blue Shield supplemental plan that covers all but my co-pay for drugs and I had no problems getting this extra help. I think I was told they'll cover up to $4000 every 6 months so go make that phone call now!

And for goodness sake seek help if you are depressed, take your meds, and if you're alone get a pet to love. I know it's hard but we can't give up or the damn RA wins!

I take Enbrel in conjuction with methotrexate and would like to stop the methotrexate as The hair loss is getting bad.
Does anyone have suggestions how to cope with the hair loss. I have had RA for 5 years and I am 69.

I have United American for my Medicare supplemental. They are expensive but with my RA and Sjogren's no one else will touch me. Just the same if you add it all up, the supplemental is losing big time with me. I am on Rituxan for RA and Sjogren's. I didn't do well at all with Remicade and had tremors from it. Methotrexate gave me a rash. Don't know what to think of above article. Didn't convince me much. I am getting a biopsy next week and then surgery for a tumor in my thyroid.

The Enbrel foundation found other revenues to help with my copay of Enbrel. Helps for those who are on Medicare.

Those who are on Enbrel. Have you looked into Enliven which is copay support program by the pharmaceutical company that makes Enbrel. Plus there are some other foundations that will offer you a grant to help pay for the expensive co pay of Enbrel and other of our expensive Rheumatoid Arthritis meds. Hope that this helps

I have had RA for over 9 years. Enbrel was prescribed after Methotrexate, prednisone and nsaids combined didn't take care of the problem. Once I got on Enbrel, it was like night and day. This drug was my saving grace. When my Insurance changed, Enbrel was not covered completely, leaving me with such a large part to pay, I quickly had to change to an infusion drug, Remicade. After 6 months I became allergic to the drug and changed to Orencia just recently. Neither drug has worked as well as Enbrel. Oh how I wish I could afford to go back on this drug. I should be thankful that Medicare and my supplemental are still paying. Who knows what the future holds with the government. Love your articles. Very informative.

Could someone please inform me: is there a supplimentary insurance that can allow the biologics (I take Remicade by drip at Dr.'s office). I am 64 and very anxious about what lies ahead with Medicare coverage.
Right now, my medical co-pays are very high, including my private insurance coverage...but, at least I am able to be on Remicade. What lies ahead for me?

I absolutely agree that these drugs bring a much higher quality of life and I am willing to live with the risks. I would rather live for 15 years with being able to enjoy my gardening and grandchildren than to live for 20 years but not be able to move out of a chair or bed. I have had RA for 15 years. The first 7 I wasn't on Enbrel and I was miserable. The inflammation and pain were awful. My insurance company finally gave the O.K. for Enbrel and it changed my life. I still have some problems due to the damage done in the first 7 years but the quality of my life has increased considerably. I can do some gardening and have my grandchildren stay for weekends and enjoy them. My only concern now is once I go off my insurance and go on Medicare what Enbrel will cost. I feel for those who insurance companies won't pay for it or they can't afford it.

I was told just having RA puts me at risk for certain types of cancer. I agree that for me it is a quality of life issue. I'm only 48 and without anti-tnf medication I have trouble even walking. I'm a nurse and I'm far from ready to roll over and play dead, and I'm not one to give up living for fear of dying. The internet is full of info that gives both hope and insills fear. I need to live one day at a time, and as a friend of mine puts it, I could get run down by a truck jogging out of the health club.

Hi I have been on biologics for 11.5 years; my body hates chemicals and I have intense reactions to all but Enbrel, which my insurance would not cover.

they work but not 100% and I am willing to keep taking them because otherwise I fear I'd be a total invalid.

I want them safe; I want them to work.

I want them to not cost as much as they do even though I have decent experience.

I certainly don't want them to increase my cancer risk; but I keep on taking them.

Quality of Life is what I live by. I would rather have some risk factors and be functional than be crippled and miserable. Medical Science will continue to make improvements in medications and dosages. Until something else comes along to help my severe RA, I am confident of living by Quality of Life.

I think this article is false reassurance for patients; anti-TNF drugs have been previously linked to Lymphoma. Also, some patients may infer from the article that anti-TNF agents are protective against cancer. In fact clinical trials of anti-TNF agents in a variety of cancer patients has shown only toxicity and no benefit.
