Doctors Matthew Seidel & Judd Cummings specialize in treating Pediatric and Adult Musculoskeletal Tumors with a focus on limb preservation. Musculoskeletal tumors can be either benign (non-cancerous) or malignant (cancerous). A critical aspect of our physicians’ expertise is the ability to diagnose each type of problem.

 

Treatment of these rare tumors requires detailed and comprehensive care. Our doctors are specialty trained to treat all tumors of the musculoskeletal system and our clinic staff actively coordinates care with other specialists.

Symptoms/Conditions Treated:

Orthopedic Oncology

Lump or bump on any limb or on the body


Most lumps and bumps are typically not cancerous. However it is very important to know what type of lump or bump you have before treatment is decided. Almost all bumps / lumps are evaluated with imaging (Ultrasound, CT Scan, MRI) to determine the exact location and type of mass. After exam and imaging our providers will recommend a treatment plan, whether it is to biopsy the mass or surgically remove the lump or bump.




Severe bone pain


Most bone pain is typically caused by injuries or arthritis; however at times pain in the bones can also come from a tumor or a bone related cancer. Our providers are leading experts in this field and are trained to evaluate, diagnose and treat the pain. It is common for diagnosis of the bone pain to start with an X-Ray. This helps our providers determine if further imagining or lab work is needed. Once the reason or diagnosis for the bone pain has been determined, our providers will provide a treatment plan that can involve non-surgical or surgical treatment options.




Diagnosis of bone cancer


Most bone cancer comes from another organ such as breast, prostate, thyroid, kidney or lung which has spread or “metastasized” to the bones. When the cancer starts in the bones the two most common types are osteosarcoma (link) and chondrosarcoma (link). Dr. Seidel & Dr. Cummings work closely with the other physicians involved in the care of our oncology patients such as medical oncologist (chemotherapy) and radiation oncologist (radiation treatment) to provide comprehensive personalized care.




Metastatic cancer of bones or a pathologic fracture


Metastatic Cancer is when the cancer comes from another part of the body such as the breast, prostate, lunch, kidney or thyroid and has moved into the bones. This happens when the cancer has moved to advanced stages and may cause bone pain. If it is not caught early, the cancer can erode the bone and cause the bone to break (also known as a pathologic fracture.)

When a patient is diagnosed with metastatic cancer it is imperative to evaluate the patient’s bones checking for erosion in an effort to prevent pathologic fractures. This helps our providers determine if the patient needs surgery or can be treated non-surgically with radiation. Our providers may recommend a surgery to stabilize the bone before it breaks. This form of treatment is known as an “impending fracture”. Determining whether a bone is stable or unstable is a difficult determination to make. It should be done by an experience and highly trained orthopedic oncologist such as Dr. Matthew Seidel & Dr. Judd Cummings.

If a patient has a pathologic fracture, it is important to seek treatment from an Orthopedic Oncologist and Orthopedic Surgeon with vast experience in treating these types of fractures. Pathologic fractures do not heal like typical broken bones, therefore specific specialized treatments and techniques are used to treat these fractures. Our orthopedic oncologist are trained in the most modern and effective methods to treating patients with pathologic fractures.




Osteosarcoma


Osteosarcoma is a form of bone cancer that starts in the bone. This cancer affects adolescents and occasionally the elderly. Treatment depends on the patient but typically involves chemotherapy and surgery. In most cases we are able to avoid amputation and save the affected limb.

Ewing's Sarcoma


Ewing's Sarcoma is a type of tumor that forms on the bone or soft tissue and is usually seen in children and young adults. The areas Ewing’s sarcomas are found is on the bones of the arms, feet, hands, chest, pelvis, spine, skull or legs. When on the soft tissue they are found on the trunk, arms, legs, head/neck, abdominal cavity or other areas.

Symptoms often include pain and/or swilling, a lump that is soft and warm, unexplained fever and a broken bone that the cause is unknown.

Chondrosarcoma


Chondrosarcoma is a rare type of cancer that normally begins in the bones, but can occur in the soft tissue around the bone. Chondrosarcoma tumors are usually found in the pelvis, hip & shoulder however; in very rare cases it can be found at the base of the skull. Depending on the type of chondrosarcoma depends on whether it will metastasize and spread to other organs and bones. Unfortunately, chemotherapy and radiation are not helpful forms of treatment and limb sparing surgery is needed to avoid amputation if possible. These tumors can occur at any age but are typically seen in middle-aged to older adults. Symptoms often include: increasing pain, swollen or noticeable mass, and fracture due to deteriorated bone.




Soft Tissue Sarcoma


These malignant tumors arise from the musculoskeletal system. Common types are Malignant Fibrous Histiocytoma, Synovial Sarcoma, Fibrosarcoma, Malignant Peripheral Nerve Sheath Tumor, Synovial sarcoma, Liposarcoma, and Epithelioid sarcoma. These tumors are generally treated with surgery, however; some of the larger and/or deep tumors are also treated with radiation. While radiation can be effective form of treatment chemotherapy is unpredictably effective in these tumors and will occasionally be given as part of the initial treatment or if cancer has spread to other parts of the body.
