Osteolytic lesion at the bottom of the radius, diagnosed by a darker section that indicates a loss of bone density. An osteolytic lesion (from the Greek words for "bone" (ὀστέον), and "to unbind" (λύειν)) is a softened section of a patient's bone formed as a symptom of specific diseases, including breast cancer and multiple myeloma.
Radiation-induced lumbar plexopathy (RILP) or radiation-induced lumbosacral plexopathy (RILSP) is nerve damage in the pelvis and lower spine area caused by therapeutic radiation treatments. RILP is a rare side effect of external beam radiation therapy [1] [2] [3] and both interstitial and intracavity brachytherapy radiation implants.
General treatment regimens have not changed much in the past 30 years, in part due to the lack of randomized clinical trials. [4] Surgery is the treatment of choice if the tumor is determined to be resectable. Curettage is a commonly used technique. [12] The situation is complicated in a patient with a pathological fracture.
External beam radiation therapy (EBRT) is a form of radiotherapy that utilizes a high-energy collimated beam of ionizing radiation, from a source outside the body, to target and kill cancer cells. The radiotherapy beam is composed of particles, which are focussed in a particular direction of travel using collimators [ 1 ] .
Spinal cord compression is commonly found in patients with metastatic malignancy. [10] Back pain is a primary symptom of spinal cord compression in patients with known malignancy. [11] Back pain may prompt a bone scan to confirm or exclude spinal metastasis. Rapid identification and intervention of metastatic spinal cord compression is ...
The last decade of studies on Modic changes have shown that Modic changes are associated with many treatment-resistant pain episodes and may result in patients entering a state of chronic low back pain. On average, individuals with Modic changes have had chronic pain for longer than individuals suffering from non-Modic changes back pain. [9] [10]
Lasers are used to treat cancer in several different ways. Their high-intensity light can be used to shrink or destroy tumors or precancerous growths. Lasers are most commonly used to treat superficial cancers (cancers on the surface of the body or the lining of internal organs) such as basal-cell skin cancer and the very early stages of some cancers, such as cervical, penile, vaginal, vulvar ...
Patient positioning is crucial at this stage as the patient will have to be placed in an identical position during each treatment. Many patient positioning devices have been developed for this purpose, including masks and cushions which can be molded to the patient. Image-guided radiation therapy is a method that uses imaging to correct for ...
