cancerous arthritis
Introduction
Introduction to cancerous arthritis Cancerous arthritis is similar to rheumatoid arthritis. It often occurs one year before the onset of cancer. The affected joint has joint pain and severe symptoms, and it has a strong sense of the morning. In the acute phase, the joints may have fever, redness, swelling and pain. Arthritis is not due to direct transfer of cancer cells to bones or joints. The disease can occur in any type of cancer patient, especially bronchial lung cancer, prostate cancer and breast cancer. Occurs in 50 to 65 years old, the incidence rate of men and women is 2:1. basic knowledge The proportion of illness: 0.001% Susceptible population: good onset age is 50 to 65 years old Mode of infection: non-infectious Complications: pneumonia, nausea and vomiting
Cause
Cause of cancerous arthritis
(1) Causes of the disease
The cause of this disease is still unclear.
(two) pathogenesis
The pathogenesis of the disease is still not clear, the disease can occur in any type of cancer patients, but especially in bronchial lung cancer, prostate cancer and breast cancer, arthritis is not due to direct transfer of cancer cells to bones or joints .
Prevention
Cancer arthritis prevention
The cause of cancer associated with mental disorders has not been fully elucidated. Cancers in various systems of the body other than the central nervous system are associated with mental disorders. The cause of this is still unclear, considering the psychological factors. Cancer patients have many bad personality characteristics before illness, such as excessive depression, poor venting, and mental and psychological disorders based on the original bad personality after cancer. In addition, non-metastatic factors caused by cancer, such as the secretion of special neurotoxins or hormones from cancer, can cause damage to the central nervous system, and the local infiltration of cancer metastasis can damage the central nervous system and also the occurrence of mental disorders. Association. Early diagnosis and early treatment are also the key to the prevention of this disease.
Complication
Complications of cancerous arthritis Complications, nausea and vomiting
(1) Pneumonia: Due to decreased immunity and bacterial infection, patients often have pneumonia.
(2) urinary tract infection: patients with rheumatoid arthritis are often prone to urinary tract infection if they do not pay attention to their daily life or suffer from a cold.
(3) Cushing's syndrome: If the patient takes too long a hormone, it is often accompanied by Cushing's syndrome due to inhibition of adrenal function in the body. Common symptoms include the full moon face, buffalo back, and weight gain.
(4) Oral ulcers: Patients with rheumatoid arthritis often experience oral ulcers after taking immunosuppressive agents, and may also have adverse reactions such as nausea, vomiting, anorexia, and loss of rash.
(5) Infectious diseases: Patients have been suffering from this disease for too long, and their autoimmune function has declined. When certain infectious diseases are prevalent in society, they are more susceptible to infection than normal people.
Symptom
Symptoms of cancerous arthritis Common symptoms Joint swelling Joint pain Morning stiffness fever with joint swelling and pain
The incidence rate of male to female is 2:1, the good onset age is 50 to 65 years old, the typical onset of arthritis, about one year before the onset of cancerous signs, and relatively rare at the same time or after the appearance of cancerous signs.
Arthritis is most common in the joints of the knees, ankles, palms, fingers and toes, followed by shoulders, elbows, wrists, hips and feet. 20% are single joints, 50% are asymmetrical, and the joints are suddenly jointed. Pain, often very serious, strong toughness in the morning, acute phase of arthritis, joints may have fever, redness, swelling and pain, different course of disease, usually relieved after malignant disease control, complete or partial remission, or chronic process , can have an acute attack, has always formed a serious loss of function.
Examine
Examination of cancerous arthritis
1. Laboratory tests often increase erythrocyte sedimentation rate, emulsion test is often negative, synovial fluid is inflammatory, no crystallization.
2. X-ray examination.
The joint bone is often normal, but the soft tissue is mostly swollen, the shadow is thickened, the invaded joint cavity is narrow, osteoporosis is often mistaken for "bone and joint tuberculosis", but the cancer invades the bone, and bone destruction can occur. Bone formation.
Diagnosis
Diagnosis and differentiation of cancerous arthritis
According to the typical onset, clinical manifestations, age of onset, and other tests to exclude other diseases, diagnosis can be made. Need to be differentiated from rheumatoid arthritis.
