Stage 2A The cancer is high grade and is only inside the bone. Anatomical compartments have natural barriers, e.

As defined by the International Union Against Cancer, the objectives of cancer staging are 1 to aid in planning the course of treatment, 2 to provide insight into the prognosis, 3 to assist in enmeking the results of treatment, 4 to facilitate effective interinstitutional communication, and 5 to contribute to continuing investigation of human malignancies [ 7 ].

Local extent for any neoplasm refers to its containment in anatomic boundaries of a compartment.

Neoplasms may be benign, pre-malignant or malignant. This is called an intracompartmental bone cancer.

Thus a fracture varies from a hairline fracture where the fracture appears as a crack on x-ray to displaced fracture where the bone has broken in its entirety with fragments going far apart.

Because all cancerous bone tumours in children are high grade, it is never diagnosed as stage 1. Select the text below and copy the link. Most osteosarcomas are diagnosed as this stage. Doctors may use the simple staging system or the Enneking staging system. Well-demarcated borders Grows slowly and stops Heals spontaneously [ osteoid osteoma ] Negligible recurrence after intracapsular resection. L6 – years in practice. Each lesion ultimately is assessed on histologic features; however, some tumors are high grade by definition, such as a dedifferentiated chondrosarcoma [ 3 ].

Recurrent bone cancer means that the cancer has come back after it has been treated.

The stage of a cancer tells the doctor how big it is and whether it has spread. It can also recur in another part of the body, which is called metastatic bone cancer. Lesions originating in the skull also behave differently and thus cannot be staged or classified using this system.

An ideal staging system should be practical, reproducible, and of prognostic significance. It is called an extracompartmental bone cancer. Read about other staging systems. It has been used widely for classification by orthopaedic oncologic surgeons around the world. Those that are not responsive to adjuvant therapy should be treated with palliative resection. This means the cancer has grown out of the area compartment of the bone in which it started.

The most common place for bone cancer to spread to is the lungs. Such tumors may be treated with wide excision, but the choice between amputation and limb salvage depends on the estimated amount of residual tumor left behind after a limb salvage procedure. The Enneking staging system is another staging system used for osteosarcoma.

Work-up is negative for metastasis, but biopsy reveals a high grade lesion. There are different systems for staging bone cancer. The Enneking surgical staging system does not consider this important factor.

Larger lesions may be more likely to metastasize and may benefit from adjuvant chemotherapy [ 10 stxging. In the Enneking staging system, a Neoplasm Neoplasm is an abnormal mass of tissue as a result of neoplasia. Use of this system along with the Weinstein-Boriani-Biagini WBB classification has been studied for spinal tumors and appears to be safe and feasible and to improve disease control and survival, although both systems show only moderate interobserver reliability and additional studies are warranted [ ennekking ].

This means it’s grown out of the area compartment of bone in which they started.
