The survey found that more than half of multiple myeloma is misdiagnosed at the time of its onset. Older people’s bodies gradually age, and bone and joint degeneration is ongoing. People tend to think that it is normal for the elderly to have back pain and leg pain. According to Prof. Du Xin, director of the Institute of Hematology of Shenzhen Second People’s Hospital, more than 2/3 of patients with multiple myeloma have back pain as the main first symptom, commonly in the chest and lower back, which worsens with activity, and are often misdiagnosed as back and leg patients for a long time due to the lack of specificity of symptoms, delaying the time of treatment. The elderly are prone to back pain and leg pain and fractures, and almost all of them would consider these to be arthritis, osteoporosis, lumbar disc herniation, etc. However, a recent study at the Shenzhen Second People’s Hospital has shown that the elderly are more prone to back pain and leg pain. However, a recent survey at Shenzhen Second People’s Hospital found that there is often a patient referred from orthopedics or other departments, or even other hospitals, which is a patient with multiple myeloma. The symptoms of this disease are complex, and patients often go to other departments for first consultation, which delays a lot of valuable time. Multiple myeloma accounts for about ten percent of hematologic tumors (the second most common hematologic tumor) and is more likely to occur in middle-aged and older adults, especially men, after the age of 50. Although it is clearly indicated, there are statistics that it has a misdiagnosis rate of about 60% to 70%. Therefore, it is necessary to raise vigilance. Orthopedic experts analyze that the high rate of misdiagnosis is due to the complexity of its symptoms. Patients facing symptoms of bone pain and other diseases tend to go to different departments separately. Therefore, once these symptoms appear, it is important to tell the doctor all so as not to delay the treatment. “Multiple myeloma is detected early in order to strive for the longest possible survival time.” How to distinguish whether a bone pain has a malignant lesion? Since multiple myeloma and general geriatric diseases both have joint pain and easy fracture symptoms, can they be distinguished? Professor Du Xin said, first of all, the elderly who have not had bone pain before, the symptoms should be seen first; if they had arthritis and other diseases before, but recently there is aggravation, or at the same time anemia, easy infection, it is necessary to link several symptoms together. Ms. Wu, who lives in Caitian Village, usually loves to sing and dance, and always likes to join a choir or go to the community to do fitness dance with a few friends. Ms. Wu is 55 years old and just retired. She had a spontaneous fracture while dancing more than half a year ago, and was treated in an orthopedic hospital, and in the past 2 months she developed back pain and could not walk, and had to be bedridden. The results of the examination surprised the family that Ms. Wu had “multiple myeloma”, a kind of malignant tumor of the blood system. Misdiagnosis delayed the disease Lying on the hospital bed, Ms. Chen looks much better than when she first arrived at the hospital, she said, “Before I was found to have this disease, I endured it at home and took some painkillers, and then came to the hospital because I could not stand it anymore.” Ms. Chen is a retired civil servant in Shenzhen, three years ago, Ms. was found to be suffering from “lumbar disc protrusion”, every time the back pain she will take a few tablets of painkillers, after a period of time, the symptoms of pain will gradually ease. This year, after the New Year, Ms. Chen began to appear again the symptoms of lumbar pain, as in the past, a pain up on a few painkillers, but the effect has been very insignificant. She has been used to suffering since she was a child, and when it hurts, she lies on a hard bed and holds it in. “I thought it was a lumbar disc protrusion, older, pain here and there is quite normal.” Ms. Chen said. In this way, Ms. Chen lay in pain on her hard bed for a full seven and a half months, and when she visited the city’s second hospital, she was pale and had little strength, because the pain was unbearable, she was not even interested in eating. When she first arrived at the hospital, the doctor felt that what she had was not a simple lumbar disc herniation or osteoporosis. After a series of tests such as bone marrow aspiration, immunoglobulin and blood tests, she was diagnosed with “multiple myeloma”, which is a malignant tumor. Professor Du Xin was very saddened to see that many patients did not come to a large hospital in time because they were suffering from pain, so he reminded the public that patients with back pain as the main first symptom must come to a large general hospital as soon as possible and tell the doctor all the symptoms to avoid misdiagnosis.
