What does needle biopsy mean

Bone and soft tissue tumors are diseases that seriously endanger human health and life. In recent years, the incidence of bone and soft tissue tumors is gradually increasing, and the age of onset is gradually decreasing. Early detection, correct diagnosis and timely treatment have an important impact on the prognosis. With the continuous improvement of examination means and methods, the accuracy of diagnosis is gradually increased, but there are still a large part of tumors do not have typical imaging characteristics, diagnosis is difficult. The correct diagnosis requires the combination of clinical, imaging and pathology. Among them, pathological diagnosis plays a key role in the selection of treatment plan. Needle biopsy is the main way to obtain pathological diagnosis. Limb salvage therapy for malignant tumors has become a major trend, which requires more stringent requirements for biopsy methods and methods. Incorrect biopsy often causes the tumor to contaminate the local important structures such as blood vessels and nerve bundles during sampling, which makes it impossible to completely remove the tumor and leads to the failure of limb salvage treatment. Therefore, before needle biopsy, it is necessary to have a full understanding of the nature, staging and treatment of the tumor, make adequate preoperative planning, and ensure that the needle passage is located on the surgical incision, so that complete resection can be performed during the operation. Therefore, a large number of literatures emphasize that needle biopsy should be performed by experienced specialists, and it is better to be performed by the surgeon himself, so as to improve the accuracy of needle biopsy and reduce complications. Needle biopsy has become the main method for histopathological diagnosis of bone and soft tissue tumors due to its simple operation, low complications and high accuracy. Therefore, we suggest that the following important principles should be followed before performing a biopsy: 1. The biopsy should be treated with the same attention and careful planning as the surgical plan. Because this is the beginning of cancer treatment, a crucial first step, an incorrect biopsy can have disastrous consequences for patients. 2. Aseptic operation principles should be strictly observed. Skin preparation and hemostasis suture should be performed as in routine surgery. 3. Ensure that the biopsy does not affect the formulation of the subsequent surgical plan, and the contaminated area of the biopsy should be able to be completely removed. 4. Ensure that there are enough representative tissue specimens for pathologists to diagnose. If the pathologist cannot make a definitive diagnosis, detailed clinical and imaging data should be provided in time. 5. If the doctor or hospital is not equipped to treat the tumor, the patient should be referred to a doctor or hospital equipped to diagnose and treat the tumor for regular treatment before biopsy.
