Following the bone scan, a Radiologist talked to me, but an Oncologist didn't. I was told that I needed to schedule an Oncology Consult. I had thought that is what I had done when I had booked the original appointment at CSU (at least that is what I was told), but it didn't appear to be the case. The thing that I learned is that you have to be very specific with the folks who are scheduling the appointments. What I should have booked was 3 appointments for a single day: Oncology Consult, Bone Scan, and Follow-up Oncology Consult.

Today, we were greeted by Katie Kennedy (a 4th year student) and 2 vet students visiting from Japan. They conducted a physical exam and took down Newton's history. Then, Dr. Ehrhart met with us. Dr. Roberts had provided me with a disk of Newton's X-Rays. Dr. Ehrhart said that based on the X-Rays and the bone scan that she was 85% sure that it was Osteosarcoma.

Dr. Ehrhart laid out the various treatment options and prognosis. Due to the location (proximal humerus), Newton is not a candidate for limb-spare. She also talked about palliative treatment, amputation, and chemotherapy. One of my concerns is if a giant breed would do well with only 3 legs. She indicated that Newton would make a good amputation candidate based on his body structure, especially since he has a fairly narrow chest.

CSU has some clinical trials that they currently have going on that Newton may be a candidate for, so Dr. Ehrhart had Dr. Momont discuss the clinical trials with me. I got a degree in Biochemistry and know the value that clinical trials can have for treatment in the future, so it was something that I inquired about.

The three Dr. Momont discussed with me were: Gene therapy for Canine Osteosarcoma, Stereotactic Radiosurgery for Treatment of Osteosarcoma, and Radiation Therapy with or without Bisphosphonate for Palliative Treatment of Canine Osteosarcoma.

I was surprised that I was not more upset when Dr. Ehrhart told me that she suspects Newton has Osteosarcoma. I guess that I prepared myself a bit before the second set of X-Rays. I have to do what is right for Newton. He needs to be happy and comfortable. So, now I am faced with the challenge: how do I want to proceed???

Today, Newton had his bone scan up at CSU. I guess that I didn't really understand going into it what a bone scan was exactly. I thought that the bone scan would tell me whether the lesion was bone cancer or an infection. What I learned is that a bone scan will pick up bone activity.

The bone scan works by injecting a radioactive chemical, sometimes called a "tracer", into the bloodstream through an IV. The chemical will attach itself to areas of bone that are undergoing rapid changes. Over a period of several hours, a lot of the tracer accumulates in the problem area(s). A special camera is then used to take pictures of the skeleton. The chemical tracer is radioactive, and therefore sends out radiation that can be captured by the camera.

When I picked Newton up, I had a consultation with a Radiologist. They indicated that there was increased bone activity in Newton's left humerus. The rest of his skeletal system was clear.

It was good news that they were able to confirm the isolated area, but I still didn't have the answers that I was looking for. Is it cancer?!?!

Today was Newton's follow up X-Rays. Since he has been being a good boy, Dr. Roberts decided that Newton could have the X-Rays done without sedation. Mary went with me to the appointment. I was a bit nervous going into the appointment because I knew that worse case scenario, the lesion could be bone cancer. As you can see in the second set of X-Rays, the area of concern had grown in size.

Newton's X-Ray 9/3

The Radiology report confirmed that the area had grown and that it hadn't spread to the chest.

Radiology Report - 9/3

Dr. Roberts' recommendation was to make an oncology consultation at CSU and have a bone scan done.

Today Newton had his first set of X-Rays. Newton's limp was getting worse. There were days when he was not himself. Then there were other days when he was full of Newton zest. Dr. Roberts sent the X-Rays up to a Radiologist at CSU for review. Here is the X-Ray of Newton's left leg.

Newton's X-Ray 8/25

The circled area is an area that has the Radiologist and Dr. Roberts concerned. Here is the Radiology report:

Radiology Report - 8/25

We decided to do a follow-up set of X-Rays and do a chest X-Ray as well.

Today we had our appointment with Dr. Eppard. Newton weighed in at 158 lbs. Dr. Eppard did a physical exam. Newton didn't have a fever. As she was doing the physical exam of his leg, Newton didn't flinch. Therefore, it was hard to see where he was hurting exactly.

Dr. Eppard's recommendation was to make a follow-up exam and have Dr. Roberts take some X-Rays. She also gave Newton Carprofen and Tramadol.

Our follow-up appointment was scheduled for August 25th.
