Sarcoma & Bone Cancer Awareness Month: Newest Technology in Imaging

bone cancer

July is Bone Cancer and Sarcoma Awareness Month. According to the American Association for Cancer Research, in 2021, around 13,000 Americans will be diagnosed with soft tissue sarcoma, while 3,600 will be diagnosed with bone cancer. Luckily, the 5-year survival rate of both types of cancer is fairly high (65 for soft tissue and 66.8 for bone). In a comprehensive study from 1978 to 2004, the survival rate of these types of cancers has improved dramatically, thanks in part to improvements in imaging and early detection.

Sarcoma is a broad term for a group of cancers found in the bone.

Advances in Radiography

While x-ray technology has been used in a health context since 1899, many features surrounding it have changed. X-rays are now more defined with higher resolution, allowing doctors to zoom in to see smaller tumors and other issues. In fact, this past year, scientists at the University of Erlangen-Nuremberg have broken the record for x-ray resolution, down to under 10 nanometers. Furthermore, the process of obtaining can now be digitized, rather than having to use a darkroom to develop scans. These developments make radiology more accessible to patients and provide more immediate results, which helps bone cancer and sarcoma patients get diagnosed earlier when time is of the essence. There are multiple types of radiography used in diagnosing these types of cancer, and specific advances have emerged and evolved the diagnostic process for each type.

 

Bone Scans

During bone scans, a patient is injected with a tracer that allows oncologists to see abnormalities. Recent changes in bone scans allow doctors to quantify the metastasis of a bone from a scan. Bone scans can sometimes occur as a diagnostic tool before a CT scan, PET scan, or MRI.

 

CT Scans

CT scans can be ordered with “contrast,” where the patient swallows or takes an IV containing a dye. This can help doctors see certain organs more clearly. These scans can also help doctors see a cross-section of parts of the body and different perspectives of organs than they’d be able to see with a typical x-ray. The latest advancements in CT scans now offerlower radiation exposure by splitting the x-ray beams, making these procedures safer than ever.

 

PET Scans 

Positron emission tomography (PET) imaging is an emerging tool for bone cancer patients receiving radiation treatments. This tool is now being used increasingly by doctors to monitor tumors between treatments. These advanced scans allow more doctors to receive more information, including receptor expression and metabolism of a tumor. This information helps doctors to understand whether or not a particular type of treatment is working to shrink tumors and to help assess the appropriate dosage.

 

MRI Scans

Magnetic resonance imaging or MRI scans help oncologists to see the extent of bone and soft tissue cancers by taking cross-sections of affected organs and allowing them to be displayed at different angles. These are taken around a patient while a patient lies still inside a long tube. The most recent changes in MRI technologyhave occurred on the software side. One relevant change includes faster scan times, thereby reducing costs and discomfort for the patient. Furthermore, multiple layers of contrast can now be taken from a single scan, allowing doctors to highlight different issues easily.

While bone and soft tissue cancers affect many Americans, advancement in imaging tools helps provide clarity and hope for these patients.
