Undifferentiated Pleomorphic Sarcoma (UPS) is the second most common bone sarcoma in adults after chondrosarcoma. Previously known as Malignant Fibrous Histiocytoma (MFH), UPS gets its name because of the way it looks under a microscope (histology). Undifferentiated describes how the cells do not look like the body tissues in which they develop. Pleomorphic means the cells grow in different shapes and sizes.
UPS is a cancerous aggressive tumors that, if left unchecked, will grow and destroy your normal bone. As the tumor slowly grows, the bone is weakened and you are at an increased risk of breaking the bone due to the tumor (called a pathological fracture). They may also spread to your lungs or other bones.
Radiographic imaging is used to help form a diagnosis. These include X-Ray, MRI, CT and Bone Scans.
An example of an UPS MRI is shown.
Treatment is a radical resection surgery with preoperative (neoadjuvant) and postoperative (adjuvant) chemotherapy.
Surgical treatment includes wide or radical resections to remove the complete tumor and additional margins. The removal of additional, surrounding margins ensures that the tumor is completely removed and decreases the chances of the tumor coming back.
Chemotherapy is a systemic treatment option for some cancers, meaning the chemotherapy drugs travel throughout the body and can kill the cancerous cells that have metastasized, or spread throughout. Chemotherapy is used to treat cancer, control/prevent cancer from spreading, and ease the symptoms related to the cancer. There are various drugs used in chemotherapy, so the combinations of drugs administered and the number of cycles may differ between each person and tumor. Lastly, chemotherapy may be used in conjunction with other treatments, specifically local treatments such as surgery.
Radiation is a treatment option for some cancers. Radiation therapy is a localized treatment that utilizes high-energy particles or waves to kill cancerous cells. Because radiation therapy is a localized treatment, it only affects the area in which it is set to target and therefore eliminates the risks of damaging healthy cells throughout the body. Not only is it used to treat cancer, but it can also decrease the chances of the cancer from recurring. Lastly, radiation may be used in conjunction with other treatments, such as surgery or chemotherapy, to treat cancers.
I've seen many doctors and I can confidently attest Dr. Wittig is the preeminent orthopaedic specialist. He is genuinely kind and caring, as he demonstrated by completely addressing my concerns and compassionately relating to what I was dealing with. He clearly outlined the plan of attack, and recommended the two additional doctors who would become part of my 'team'. Dr. Wittig was so effective in allaying our fears and bringing us optimism. My surgery was significant, but I was up and walking the next day and back at the gym 5 weeks later. This is further testament to Dr. Wittig's skill. He saved my leg and my life, and I feel so very blessed to say he is my doctor. I have already recommended him to others, and I will continue to do so. I would trust him with my closest family and lifelong friends. BEST DOCTOR EVER.
