Stage 4 bone cancer prognosis should begin with the definition of the stage.
Annually, many thousands of people are diagnosed with bone cancer. Malignant tumours that are confined in the bone, is called primary bone cancer. Malignant tumours in other organs spread, or metastasize, to the bone in Stage 4 cancer.
Various types of bone cancer have been categorised depending on the part of the bone where the tumour is localised. Some of them are chordoma, fibrosarcoma, Ewing’s sarcoma, and osteosarcoma etc.
The stage 4 bone cancer prognosisis difficult to predict but we may describe the symptoms below:
Stage 4 bone cancer prognosishas improved significantly on account of advances in chemotherapy and the discovery of new drugs that fight cancer.
The chances of recovery vary according to various factors such as overall fitness of the person, age and mental strength, how far the cancer has spread. It also depends on the size, location; extent the cancer can be removed by surgery, how much of it can be killed by chemotherapy and radiotherapy.
When the tumour is small and localised, 90 per cent of patients live for at least five years. He five- year survival rate decreases to 60 per cent and prognosis becomes poor once the cancer spreads.
Hereditary and genetic factors may influence survival rates and this may vary according to race and sex.
Generally, stage 4 bone cancer prognoses indicates a survival rate of nearly 32% and about 15% cases are diagnosed at this stage. Even though the exact staging information is not available for about 8% of the total bone cancer cases diagnosed, the survival rate for these cases is around 63%.
Of paramount importance is early diagnosis of the disease which gives doctors a chance to choose the correct treatment to combat it. This halts the progress of the cancer to other sites and improves survival chances. Of paramount importance is the patient’s inherent will to survive and take the pains of these treatments in their stride.
In conclusion, stage 4 bone cancer prognosis depends on the nature of the cancer and the extent it has spread to other organs in the body. The patient suffers intense pain, bones and bone joints swell, fractures occur, which renders the person immobile. Other factors that influence survival chances are genetic in nature and race and sex seem to have a bearing on survival chances.
Modern drugs and therapies have improved thestage 4 bone cancer prognosis. Of note is the attempt to shrink tumours with the aid of chemotherapy and well directed radiotherapy after MRI scans and its subsequent removal by surgery. Bone grafts and metal implants have helped patients to have a better quality of life.
