The stages of prostate cancerThe stage of a cancer tells the doctor how far the cancer has spread. Localised prostate cancer is cancer that is completely contained within the prostate gland. Locally advanced prostate cancer is cancer that has broken through the outer covering (capsule) of the prostate gland. If you would like to talk to someone about the stages of prostate cancer, you can contact our cancer information nurses.

January 1, 2011In the article Bone Tumors - Differential diagnosis we discuss a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions. In this article we will discuss the differential diagnosis of well-defined osteolytic bone tumors and tumor-like lesions.
These lesions are sometimes referred to as benign cystic lesions, which is a misnomer since most of them are not cystic, except for SBC and ABC. It is true that in patients under 30 years a well-defined border means that we are dealing with a benign lesion, but in patients over 40 years metastases and multiple myeloma have to be included in the differential diagnosis.
On the left a table with well-defined osteolytic bone tumors and tumor-like lesions in different age-groups. In patients > 40 years metastases and multiple myeloma are by far the most common well-defined osteolytic bone tumors. Patients with Brown tumor in hyperparathyroidism should have other signs of HPT or be on dialysis.
Differentiation between a benign enchondroma and a low grade chondrosarcoma can be impossible based on imaging findings only.
Most bone tumors present as well-defined osteolytic lesions, sometimes referred to as 'bubbly lesions'.
You can use the table above, but another way to look at the differential diagnosis of well defined osteolytic bone lesions is to use the mnemonic Fegnomashic, which is popularized by Clyde Helms (1). Some prefer to use the mnemonic Fogmachines, which is formed by the same letters, but is a real word.
Fibrous dysplasia is a benign disorder characterized by tumor-like proliferation of fibro-osseus tissue and can look like anything. If periosteal reaction or pain is present, exclude fibrous dysplasia, unless there is a fracture.


In some locations it can be difficult to differentiate between enchondroma and bone infarct. It is almost impossible to differentiate between enchondroma and low grade chondrosarcoma based on radiographic features alone. EG is a non-neoplastic proliferation of histiocytes and is also known as Langerhans cell histiocytosis. It should be included in the differential diagnosis of any sclerotic or osteolytic lesion, either well-defined or ill-defined, in patients under the age of 30. Malignant GCT is rare and differentiation between benign or malignant GCT is not possible based on the radiographs. GCT is also included in the differential diagnosis of an ill-defined osteolytic lesion, provided the age and the site of the lesion are compatible. NOF: typical presentation as an eccentric, multi-loculated subcortical lesion with a central lucency and a scalloped sclerotic margin. The radiographic appearance is almost always typical, and as such additional imaging and biopsy is not warranted. Consider osteoblastoma when ABC is in the differential diagnosis of a spine lesion (figure). A typical osteoblastoma is larger than 2 cm, otherwise it completely resembles osteoid osteoma.
Metastases must be included in the differential diagnosis of any bone lesion, whether well-defined or ill-defined osteolytic or sclerotic in age > 40.
Metastases can be included in the differential diagnosis if a younger patient is known to have a malignancy, like neuroblastoma, rhabdomyosarcoma, retinoblastoma.
Multiple myeloma must be included in the differential diagnosis of any lytic bone lesion, whether well-defined or ill-defined in age > 40.
The most common location is in the axial skeleton (spine, skull, pelvis and ribs) and in the diaphysis of long bones (femur and humerus).
In the left sacral wing there is a larger lesion with a high density due to replacement of fatty bone marrow by myeloma (red arrow).
ABC is a solitary expansile well-defined osteolytic bone lesion, that is filled with blood.
ABC is thought to be the result of a reactive process secondary to trauma or increased venous pressure.

It has a broad spectrum of radiographic features and occurs at any age and has no typical location. In the acute stage it can mimic a malignant bone tumor with ill-defined margins, cortical destruction and an aggressive type of periostitis. Only when there is a thick solid periosteal reaction we can recognize the non-malignant underlying process.
Chondroblastoma: notice extensive edema (middle) and fluid-fluid level due to secondary ABC.
The patella, carpal and tarsal bones can be regarded as epiphysis conceirning the differential diagnosis.
Although the name suggests that CMF is a chondroid lesion, calcifications are usually not seen. Low power photomicrograph of the biopsy specimen shows tumor osteoid produced by a malignant-appearing osteoblastic cell. Shortly after this the patient developed a recurrence of the giant cell tumor in the proximal tibia for which she had an above-knee amputation. It is important because knowing the stage helps doctors decide the best treatment.You may hear your doctor talk about your cancer stage as TNM.
The tests and scans you have when diagnosing your cancer give some information about the stage.
Doctors look at different factors to divide these into groups according to whether they are likely to grow quickly or slowly or whether they are likely to spread.
Typical enchondromas in the femur and tibia as seen frequently as coincidental finding in MR-examinations.
It is important because knowing the stage helps doctors decide on which treatment you need. You can read about the low risk, intermediate risk and high risk groups on our page about risk factors in localised prostate cancer.
So even if the tumour appears to be very small, when a bone scan shows that there is cancer in the bones, the prostate cancer is M1 stage.
It will be treated as metastatic cancer and can often be controlled for several years with treatment.
