ANSWER:
ANSWER: Testicular cancer is one of the rare cancers that can secrete “tumor markers,” or molecules that can be detected in the blood. The three common tumor markers for testicular cancer are AFP (alpha-fetoprotein), HCG (human chorionic gonadotropin) and LDH (lactate dehydrogenase). You can learn more about each of these tumor markers at: http://urology.jhu.edu/testis/testis_cancer_markers.php.
A recent story on the internet highlighted the story of a young man who was “diagnosed” with testicular cancer by using an over-the-counter pregnancy test. While I don’t know this patient, I’m sure his story is true – I’ve had a few patients in my practice who had a “positive” pregnancy test before coming to see me. However, this young man, Byron Geldard, had doctors in Cambridgeshire, Engand, puzzled when he presented with pain in his side and an uncertain malignancy that had spread around the body.
(This story was reported in The Telegraph, March 9, 2015: Teenager Diagnosed With Testicular Cancer After Pregnancy Test). The doctors in Great Britain used a pregnancy test to confirm the diagnosis of testicular cancer in Byron – creating a sensational news story.
While it worked in this circumstance, an over-the-counter pregnancy test is not a great test to diagnose testicular cancer. Knowing that testicular cancer would be the most common malignancy in an 18 year-old man and ordering simple blood tests could have also confirmed the diagnosis of testicular cancer in Byron. Since this story has been plastered around the internet and social media, here’s the truth about HCG, pregnancy tests and testicular cancer…
Pregnancy tests work by detecting HCG in the urine – the same protein that can be secreted by some testicular tumors. So, if you have a testicular tumor and it secretes HCG, a home pregnancy test may confirm that diagnosis. However, HCG is only rarely secreted by testicular tumors:
• Only 15% of early-stage seminomas and 20-40% of NSGCT (non-seminomatous germ cell tumors) will secrete HCG.
• Even in cases of advanced (metastatic spread to lymph nodes or other sites) testicular cancer, only about 50% of tumors (seminomas or NSGCT) will secrete HCG.
In addition, HCG levels need to be relatively high to be detected by the over-the-counter urine tests. Some urine pregnancy tests will detect HCG levels of 20 mIU/mL, but most rely on levels >100 mIU/mL. Of the minority of testicular cancer patients whose tumors secrete HCG, many patients will have HCG levels beneath the detecting capability of a home pregnancy test.
Therefore, HCG (and pregnancy tests) are an unreliable screening test for testicular cancer. If you feel an abnormality during testicular self-exam the first thing you NEED TO DO is contact a physician and make an appointment. If the doctor is concerned, an ultrasound (painless) and blood tests (mostly painless) are the next correct steps. If you’re curious while you wait, try a pregnancy test. If it’s positive then you know the diagnosis and find the nearest testicular cancer expert. If the pregnancy test is “negative” that does NOT necessarily mean that you do NOT have testicular cancer. Remember, upwards of 80% of testicular cancers will NOT secrete HCG so do not rely on a home pregnancy test to prove you are cancer free!
QUESTION : When I was diagnosed with Testicular Cancer I was very nervous, and experienced heightened emotions. After leaving the doctor appointment I felt I didn’t get a chance to express myself due to news I had just received. When diagnosed is it ok to get second opinions or look into possible alternative options? I read a lot of different things on the internet but I am thankful for this reliable resource. –Kyle, Salt Lake City, Utah
ANSWER: Thanks for the great question, Kyle. I think its very important to get a second opinion, and more importantly, to get a second opinion from someone who specializes in Testicular Cancer.
First, I recommend all patients with a life-changing diagnosis to get a second opinion. If you had appendicitis or a pneumonia, most physicians can care for that without issue. Even if you like the first doctor you see, a second opinion is definitely warranted for a new cancer diagnosis. In fact, I recommend that most of my new patients to seek a second opinion to make sure they understand all of their options.
Second, Testicular Cancer is a relatively rare disease and not all urologists, medical oncologists and primary care physicians understand the nuances of treatments and their side effects. Consider this: there are approximately 10,000 urologists in the country and an estimated 8,000 men diagnosed with TC each year. Therefore, on average, each urologist sees one TC patient per year. It’s not their fault, but you want to get an opinion from someone who sees a lot of TC patients. Ultimately, you may return to the first urologist (or physician) you saw – and there’s nothing wrong with that either, but you should certainly seek an “expert” opinion.
I am happy to see any new TC patients at Hopkins, but there are many great centers around the country that can help you and we would be happy to point you in the direction of the one closest to you. – Dr. P
