Do you know the symptoms of osteosarcoma or the details of the surgery?

 

Osteosarcoma is a rare cancer that occurs in bones. It often occurs around the shoulders or knees of teenagers and 20s, so symptoms may not appear until bone changes or may be mistaken for growth pain. If you suspect osteosarcoma, see an orthopedic surgeon immediately. This time, we will explain the symptoms and causes of osteosarcoma, test and treatment methods, age differences, gender differences, and post-treatment.

What is osteosarcoma?

What kind of disease is osteosarcoma?

Bone sarcoma include osteosarcoma, cartilage sarcoma, ewing sarcoma, and colger celloma. Sarcoma is a cancer that refers to a malignant tumor that occurs in bones, muscles, fat, blood vessels, and nerves. Osteosarcoma is the most famous malignant tumor in bone.

There are two types of cancer that occur in bones. It is a metastatic bone tumor in which cancer spreads to the bone, as well as cancer from other organs. Among them, most of the primary malignant tumors are osteosarcoma.

Osteosarcoma is a cancer that can occur anywhere in the body, but bone sarcomas account for about 25% of all sarcomas. The incidence is rare, with one in 500,000 people, and it can be said to be a representative rare cancer in a small number.

Please tell me where osteosarcoma occurs frequently.

The areas that occur frequently are around the knee joints such as the femur knee or the shinbone knee, or the humerus shoulder. Osteosarcoma often occurs in the 10s and 20s, and pelvis or spine often develop in the middle age.

Please tell me about sarcomas that occur in bones other than osteosarcoma.

There are cartilage sarcomas, ewing sarcomas, and colger cell types that occur in bones other than osteosarcoma. Cartilage sarcoma is a sarcoma that occurs a lot in the femur, pelvis, and humerus. It happens a lot, especially in people over the age of 40. The treatment focuses on surgery because anti-cancer drugs or radiation therapy cannot be expected to be effective.

Ewing sarcomas occur not only in bones but also in soft tissue in the body. It is a common sarcoma in people under the age of 20 who usually occur in the femur, pelvis, and spine. Treatment includes surgery, chemotherapy, and radiation.

One of the osteoblasts is technically not a malignant tumor. It is known as an intermediate malignant tumor because it is likely to metastasize and recur. It is a tumor that often occurs around the 20s. The symptoms are small and may be asymptomatic until fracture. Treatment is divided between medication and surgery.

osteosarcoma symptoms

The main symptoms of osteosarcoma are pain and swelling. However, symptoms may not appear until an X-ray finds an abnormality in the bone. Pain or swelling also occurs in growing pains or sports injuries. Osteosarcoma often occurs in teenagers who are active in growth, so it is often judged as growth pain as a symptom.

In addition, it is difficult to diagnose with symptoms alone because there are similar symptoms in deformable diseases. If symptoms do not appear even though there is osteosarcoma or self-judged as growth pain, it is sometimes found after bone weakness and pathological fracture as sarcoma progresses.

If a fracture occurs, treatment may become difficult, so if a doctor says that osteosarcoma is suspected, let's not use crutches to put weight on the suspected area. Pain and swelling can last for months to more than half a year, so if you are not injured and the pain or swelling does not go away for more than a month, see a doctor immediately.

the cause of osteosarcoma

The cause of osteosarcoma is unclear. The genes that cause it are not identified. It often occurs during growth, but there are also secondary outbreaks caused by radiation irradiation and elderly people.

If you have pain, see an orthopedic surgeon. It is rare, but it may have spread to the lungs, so if it is not a clear injury, don't judge yourself by growth pain and see a doctor quickly. Also, since it is a rare disease, let's conduct treatment at a facility or doctor with extensive treatment experience.

an osteosarcoma test

First, check your age and time of occurrence through the questionnaire. If sarcoma is suspected, a blood test, X-ray, CT, and MRI are performed to check for tumor bone formation. In order to be confirmed, tumor tissue is surgically collected and biopsy is performed, and a pathologist's diagnosis such as positive or malignant is required. In addition, improper biopsy may contaminate the tissues around the tumor, so it is recommended to perform biopsy in a professional facility.

the difference in age and sex of osteosarcoma

Of those with osteosarcoma, 60% are in their 10s and 20s and 30% are in their 40s and older. Older people in their 60s and older can also develop it. Male and female ratio is 1.5:1, which is a little bit of a trend for men.

a cure for osteosarcoma

In osteosarcoma treatment, anticancer drug treatment and surgery are mainly performed. The standard treatment method in the world is preoperative chemotherapy, surgery, and postoperative chemotherapy. Radiation therapy can't be very effective.

Because chemotherapy is required before and after surgery, the treatment period is from six months to a year. The operation involves extensive resection. It is a method of resecting a tumor by wrapping it around healthy tissue so that it does not leave tumor cells. We also remove some of the normal bones and muscles around the tumor.

We aim for a replacement zone that does not cut the limbs as much as possible, but may need to be amputated in the case of pathological fractures or if the tumor is winding around important blood vessels or nerves.

In addition, even if you can preserve it, you may have to use reconstruction or artificial joints that use your bones. Customized kidney-type artificial joints are widely used in artificial joints for children.

Osteosarcoma was once called an incurable disease. However, if there is no metastasis at the time of the first visit, the 5-year survival rate is about 70% due to improved life prognosis due to chemotherapy.

after osteosarcoma treatment

Osteosarcoma is a malignant tumor, so there are many cases of recurrence or metastasis. Even if recurrence or metastasis occurs, regular hospitalization and examination are required to quickly detect and start treatment.

In particular, children may need re-surgery due to growth, and there is a risk of leukemia due to side effects of anticancer drug treatment, so regular hospitalization and examination are more necessary.

Let's go to the hospital regularly for 10 years after treatment. There are cases of recurrence or metastasis after 10 years, so let's see a doctor once a year after that.

arrangement

Osteosarcoma is the most famous malignancy in bone, and it is a rare cancer that can be said to be representative if it is small. The areas that often occur in the 10s and 20s are around the knee joints such as the femur knee or the shinbone knee, or the humerus shoulder. The main symptoms are pain or swelling, but symptoms may not appear until an X-ray finds an abnormality in the bone. The cause is unclear. If suspected, blood tests, X-rays, CTs, and MRIs are performed, but biopsies are required for confirmation. In treatment, chemotherapy and surgery are mainly performed. Since recurrence or metastasis often occurs, regular hospitalization and examination are required even after treatment. If the pain persists for more than a month without a clear injury, you can receive orthopedic treatment because of self-determination due to growth pain.
