Bone Cancer Types

Cancer-induced bone pain sequentially activates the ERK/MAPK pathway in ...

Background Previous studies have demonstrates that, after nerve injury, extracellular signal-regulated protein kinase (ERK) activation in the spinal cord - initially in neurons, then microglia, and finally astrocytes. In addition, phosphorylation of ERK (p-ERK) contributes to nociceptive responses following inflammation and/or nerve injury.

However, the role of spinal cells and the ERK/MAPK pathway in cancer-induced bone pain (CIBP) remains poorly understood. The present study analyzed activation of spinal cells and the ERK/MAPK pathway in a rat model of bone cancer pain.Results A Sprague Dawley rat model of bone cancer pain was established and the model was evaluated by a series of tests.

Moreover, fluorocitrate (reversible glial metabolic inhibitor) and U0126 (a MEK inhibitor) was administered intrathecally. Western blots and double immunofluorescence were used to detect the expression and location of phosphorylation of ERK (p-ERK).

Our studies on pain behavior show that the time between day 6 and day 18 is a reasonable period ("time window"as the remaining stages) to investigate bone cancer pain mechanisms and to research analgesic drugs. Double-labeling immunofluorescence revealed that p-ERK was sequentially expressed in neurons, microglia, and astrocytes in the L4-5 superficial spinal cord following inoculation of Walker 256 cells.

Phosphorylation of ERK (p-ERK) and the transcription factor cAMP response element-binding protein (p-CREB) increased in the spinal cord of CIBP rats, which was attenuated by intrathecal injection of fluorocitrate or U0126.Conclusions The ERK inhibitors could have a useful role in CIBP management, because the same target is expressed in various cells at different times.

Facts about bone cancer reveal that this is caused by a malignant tumor in the bone that destructs the normal bone cells. The primary types are rare and are found less than even 1% among the total number of cancer patients goes through cancer rather than treatment. Symptoms of this disease must be known if want to start treatment early and the causes is mainly the malignant tumor. Pain is the most common symptom of this disease, but not all bone cancers cause pain. Persistent or unusual pain or swelling in or near a bone can be caused by cancer or by other conditions.

Causes:

This disease is seen in the cells that are responsible for the construction of the bones. Already more than 2000 people only in US are diagnosed with this. Bone tumors are found to attack mainly among children and adolescents and are found to be really less in old adults. Causes of this disease depend on the type of the bone cancer. Let us look at some of the types so that we can understand the causes, 1. Osteosarcoma: This is the most common cause of primary malignant bone cancer and is found to commonly affect male of 10 to 25 years of age. It is found to be caused in long bones like arms and legs as also rapid growth of this can be found in neck. The five year survival rate is 65%2. Ewing’s Sarcoma: This is the most aggressive of all types. This causes through the malignant tumor which is more and more aggressive in its nature. It is most commonly seen among 4-15 years of age group and the survival rate is of 65%. 3. Chondrosarcoma is the second types which are found to affect the most commonly. The rate is around 25% of the total patients are affected with this type of tumor. The 5 years survival rate is of 90%. 4. Fiborsarcoma is very rare among bone cancer types. It is found to be most common among people with 35-55 years of age, it is found to affect the soft tissue of the leg. 5. Chrodoma: is the rarest type. This bone cancer causes to adults of 30 years of age. It is pretty common in male than female.

You once you know the Facts about bone cancer types you will be able to treat them in proper. Bone cancer treatment has shown an average life of 5 years. Symptoms of this disease also differ with the type but the very first symptom in every type is the malignant tumor.
