Almost every lung cancer survivor has a positron emission tomography (PET) scan these days. Now, a PET is often given with a computerized axial tomography (CT) scan. The diagnostician is a radiologist; a discipline that does not write in lingua franca. What do the report words mean? Here is a summary of my August PET-CT to interpret radiology speak. INDICATION: (Why am I getting this scan) “The patient…with non-small cell lung cancer of the right main bronchus diagnosed in 2003 status post pneumonectomy….He has undergone previous surgery for bronchopleural fistula repair…Chemotherapy last administered May 2006…Cyberknife therapy for recurrent disease in March 2007…He more recently has cough and chest discomfort.” That’s me, no doubt, but this summary is important. Radiologists see many scans and sometimes results are misreported. TECHNIQUE: (Test scope and method) Note details about the accuracy of the CT. “These images do not constitute a diagnostic-quality CT….” The CT results help to precisely map or locate the PET results but cannot generate a diagnostic grade image. COMPARISON: (Other scans reviewed while looking at this one). “Report only (no image reviewed) from PET-CT 3/8/2013. CT of chest and abdomen 8/22/17 (looked at image).” A CT scan is normally performed first. PETs follow and accuracy is enhanced if the radiologist has access to prior images. To improve access, have all your scans done at the same medical facility. FINDINGS: (The result) “…showed no convincing PET evidence of FDG-avid (fluorodeoxyglucose — radioactive tagged glucose seeking) recurrent or metastatic disease.” This is what we want to see in the first sentence. Then, the radiologist peels back the onion with detail. “There is mild heterogeneous hypermetabolism (diverse increased rate of metabolic activity)…with a few small superimposed foci (above the hypermetabolic area that is of particular interest)…more intense activity showing a maximum SUV of 3.5 (SUV — standardized uptake value)….When compared to [past reports] uptake…showed SUVs ranging from 2.6 to 2.9. This is strongly favored to be inflammatory.” Relief —this is my chronic pain site caused by 3 thoracic surgeries in the same location! “A somewhat retractile appearing mass (drawn back into lung tissue)…in the left upper lobe is stable in size…This shows minimal uptake…and is most compatible with the site of treated tumor.” My CyeberKnife-fried tumor scar. I do love precision radiation! What are concern ranges for SUV uptake? First, consider what is measured — cellular metabolic rate; more simply is demand for glucose, the fuel of metabolism. Cells with high metabolism ingest more tagged glucose. The PET shows differences in consumption (uptake). SUVs below 2.0 are normal. SUVs above 2.0 are suspect but between 2.0 and 4.0, uptake could be from injury or inflammation. Readings above 4.0 tend to be cancer but there can be other explanations. Higher than 4.0 is likely cancer, especially when paired with a CT find. Cancer demands glucose to fuel mitosis or growth by cellular division. Get and keep copies of all your diagnostic imaging. Keep track of the findings. I use a spreadsheet to record date, location and indications. Dr. Google is a great source for medical definitions. The best possible outcome for any scan is NED (no evidence of disease). May NED be with you. Stay the course.
MY STEPS TO SURVIVING A LUNG CANCER DIAGNOSIS Step 1 – Invest in sophisticated diagnosics before diagnosis If you smoke, were a long-term smoker, or are in an occupation that exposes you to carcinogenic toxins (asbestos removal, auto mechanic, painter, etc.), I suggest getting a computed tomography (CT) scan, often called a CAT scan, of the chest once a year. Insurance now covers it and CT will detect tumors far earlier than a chest x-ray. Early detection of small tumors dramatically enhances your survival chances. I had a chest x-ray in January 2004 and was diagnosed with stage 3b, non-small cell lung cancer the following month. The tumor hadn’t shown on the x-ray; but at diagnosis, it was almost 3 inches long and ½ inch in diameter. The only symptom I had was coughing up blood the day before diagnosis. Learn more about early CT screening. Step 2 – Choose a good general practitioner Your general practitioner may be the manager of your lung cancer treatment. The GP likely will pick your cancer team and may need to do a little arm-twisting to get things moving. Therefore, there can be great benefits to having a GP who is seasoned and well known in the medical community. I prefer doctors of osteopathic medicine to medical doctors. I’ve found that in my experience the former treat people, not patients. I believe a good physician shows kindness, consideration, and compassion toward those in his or her care. These characteristics are essential. Be sure you know your GP and your GP knows you. Such knowledge and trust will give you a survival edge. There are great health care professionals out there. Step 3 – Ensure your oncologist is a physician A doctor has a degree in medicine and a license to practice. A physician is devoted to restoring, maintaining, and promoting your good health. My physician oncologist does a complete examination (looks in eyes, nose, and throat, checks pulse in the extremities, checks reflexes, listens to breathing and heart rate) every visit. He reviews and explains all test results and asks how I feel. He looks at me as I speak, and he listens and makes notes on what I say. He carefully explains medical treatment alternatives that may arrest the disease, and together we choose each next step. He never rushes consultations and, consequently, often is late to scheduled appointments. Because his tardiness results from spending time with those he treats, I know he cares about me and every other patient. These are some characteristics your physician oncologist should possess. Step 4 – Learn about your disease At diagnosis, I had no idea what lung cancer was. Moreover, I didn’t know what an oncologist did, nor could I spell the word! After diagnosis, I read everything I could find about the disease; a good resource is the www.LUNGevity.org website. Then I read medical journals, government reports, research papers, and studies. I made notes about things I didn’t understand and asked questions at my oncology consultations. My wife attended every consultation, procedure, and test to ensure every question was asked and answered, and that we understood the answers. You need to know about type, stage, statistics, radiation, diagnostics, chemotherapy, side effects, surgical options, and so much more. Your chances of survival are improved if you are informed enough to ask highly perceptive questions. Step 5 – Acquire a sanguine attitude quickly Cancer is a disease of death; lung cancer kills more than all other cancers. Your attitude toward treatment is, I believe, essential to survival. When you acquire a sanguine attitude, your treatment team will notice your optimism. They will enjoy interacting with you; they will care about you. I strongly suggest you read Stephen Jay Gould’s essay “The Median Isn’t the Message” to help you understand survival statistics and find optimism about what appear to be bleak probability of survival projections. Join a cancer blog or messageboard. I am a member of several where I can broadcast my complaints and protestations to people who understand and have useful advice for coping. Find cancer support groups and join one. Most people who treat you have no idea how you are feeling. But survivors in cancer support groups understand; they know how you feel—you’ll fit right in! Step 6 – Any port in a storm There is no such thing as “a little stick!” During procedures and treatment, almost everyone will attempt to gain access to your veins with an intravenous device of some type. All such intrusions are uncomfortable, and unless the practitioner is good and lucky he or she will miss more often than not. If your treatment involves intravenously administered chemotherapy, you likely will get stuck at least once a week. A good way to avoid discomfort and frustration is to ask for a port. Installation involves simple, low-risk surgery. Once in place, you need to keep the area clean and exercise precautions when bathing—but access to your veins is no longer a storm but a port in a storm! Step 7 – Don’t believe the miracle cure The consequences of a lung cancer diagnosis are frightening. For most, it will be your first serious encounter with the prospect of death. When you type “lung cancer” into Google, you will be bombarded by advertisement that promises miracle cure at considerable expense. There is no such thing as a miracle cure! Before you invest time (now precious) investigating one of these “too good to be true” remedies, check it out on www.quackwatch.org and discuss it with your physician. Oncology is a medical science. Procedures, drugs, and protocols are tested using scientific methods that are published and reviewed by peers and regulating organizations. When science-based breakthroughs are discovered, they are broadcast very quickly throughout the practitioner community.Read about Steve Jobs—one of the smartest technologists and businessmen the world has ever known—who delayed his cancer treatment. Step 8 – Don’t try to tough it out I am a retired soldier and believed I was man enough to handle almost anything. Cancer proved to be the “anything” I could not handle! I suffered a long time trying to tough it out before I admitted I was depressed. My physician’s response: “Of course you are depressed—how could you not be?” He prescribed appropriate medication, arranged consultations with a psychologist, and suggested I attend support groups. Unless you are tougher than I, you will experience depression. Admit it and accept help. Here are some other things you might try. Ask for the “freeze spray” before an IV is used. If claustrophobic, get a script for Xanax and take it shortly before scans. Even in summer, wear warm clothing to diagnostic and infusion sessions. Some areas where these take place are kept very cold. Many treatment centers have volunteers—engage one in conversation. Many are survivors or caregivers and have a wealth of helpful information. During consultations, I was so frightened I couldn’t rationally ask questions about results or next steps, and I certainly couldn’t remember what was said. Consequently, I never go alone to a consultation. I suggest if you can, always have someone with you too. Step 9 – Become a calendar maniac If you have a smartphone with a calendar application, become an expert in its use. If not, keep a paper “cancer calendar” to record information. Your life after diagnosis will likely become filled with scheduled appointments, and given the nature of the disease and intensity of the battle, these are appointments you don’t want to miss. For example, my chemotherapy cycle required an infusion every third Friday. I had to record three rounds of steroid medication taken every six hours before each infusion. I had a scheduled blood test every Monday following infusion. Nausea started Sunday morning and lasted until Tuesday. Joint pain started Wednesday and lasted until Saturday. If I took the nausea medication about an hour before onset, symptoms often were minimal. Furthermore, if I started pain medication a couple of hours before onset, my pain was manageable. I used the alarm feature on my phone to warn me in advance. Plus, there was life to live, and the calendar helped me avoid conflicts between my cancer treatment schedule and my life events schedule. Step 10 – Choose to live When asked about my cancer experience, I often tell those in treatment that cancer is a disease of life or death. I believe if you choose treatment, you are choosing life. And if you choose to live, do something with the life you are given. The “something” will be different for each of us, but doing whatever you enjoy or find fulfilling is so important. If you enjoyed an activity before diagnosis, do it afterward. Look at yourself in the mirror every morning. If you don’t see an expiration date stamped on your forehead, then enjoy the day and look forward to the next! Oh, by the way, your hair will grow back! Baldness is a beautiful badge of courage. Stay the course.
