Bone tumors can reach any bone in the body, but they are more common in long bones, such as arms, legs, spine and pelvis. The tumor can appear directly on the bone (primary) or cancer in another organ, with bone metastases (secondary). Any tumor can develop metastases, but they are more common in the bad, lungs, prostate, thyroid, kidneys and digestive tract.
The month of July, called July Yellow, was chosen to raise awareness. the disease and the importance of early diagnosis for faster and more effective treatment. According to data from the National Institute of Traumatology and Orthopedics Jamil Haddad (Into), bone tumor accounts for 1% of oncological pathologies in Brazil, and 10% of cancer patients end up with bone metastases .
Bone tumors are rarely fatal but are dangerous and require treatment. Symptoms include bone pain, swelling and tenderness in the affected area, fragile bones, fatigue, weight loss and fever. Nuclear medicine has two tests that identify bone cancer metastasis before anatomical changes, that is, before they are visible. The scanner badesses organ function and presents an imaging diagnosis, generated by intravenous injection of the 99mTc-MDP radiopharmaceutical, which is the most commonly used method. captured by the bone tissue and marking the tumors present – visualized by means of a special equipment that creates a skeletal image, in addition to indicating possible metastases – if the disease has spread to d & # 39; Other bone, and evaluate the damage to the bone reached
The bone scan also helps to diagnose a fracture when it is not visible on X-rays. In addition, the examination can also diagnose bone infection (osteomyelitis) and metabolic disorders such as osteomalacia, primary hyperparathyroidism, osteoporosis, complex regional pain syndrome and Paget's disease This technique allows detection of lesions up to four months before radiography.
The radioactive material is removed by the urine and disappears from the body in 24 hours. PET / CT
PET / CT is a highly specific test for the early detection of carcinogenic concentrations in the blood. in addition to identifying possible metastases. The method combines PET / CT (positron emission tomography and computed tomography) already established with tracers (radiopharmaceuticals) captured by cancer cells. In this test, a radiopharmaceutical is injected into the patient's vein, which focuses on the tumor lesions, locating the foci of the tumor. metastases. An badysis of the whole body is performed with great precision. According to the nuclear medicine doctor and vice president of the Brazilian Society of Nuclear Medicine, George Barberio Coura Filho – clinical agent of Dimen SP (www.dimen.com.br), PET scan can help diagnose whether the disease has evolved to determine who is the best treatment for fighting cancer and ensuring a better quality of life for the patient. "This technology allows us to know the exact location of the cancer and determine its extent, which allows to choose the right treatment for the type of lesion," says the specialist. The treatment of bone tumors may require surgery, chemotherapy, radiation therapy or a combination of them.
Still little known to Brazilians, the specialty badyzes the anatomy of organs and their functioning over time. enabling earlier and more accurate diagnosis and treatment. The practice acts in detecting alterations in the functions of the body affected by cancers, heart disease and neurological problems, among others.
Nuclear medicine relies on high-tech exams, such as PET / CT, which is capable of metabolic mapping of the body and captures very high resolution anatomical images with three-dimensional reconstruction, accurately locating nodules, lesions tumoral and innumerable other clinical conditions. SPECT / CT is the fastest, most accurate and least irradiating radiotherapy diagnostic technology allowing a better anatomical location of scintigraphy results, allowing a more precise and less invasive procedure.
About DIMEN 19659003] DIMEN – a reference in nuclear medicine in the country, with more than 36 years of operation – has twelve units in the interior of São Paulo and Minas Gerais. In Brazil, it is a pioneer in the use of radio-guided surgery and PET-CT technology. The new unit in the city of São Paulo is located at Av. Conselheiro Rodrigues Alves, 325, Vila Mariana. DIMEN is the first nuclear medicine clinic in Latin America to receive the "QMentum International" certificate from the Canadian Council on Health Services Accreditation (CCHSA), with international quality and safety performance criteria. , granted to all units in the last year.
