Bone Metastases in Lung Cancer Patients Linked With Poorer Prognosis

A pair of studies from the ASCO annual meeting examined bone metastases from lung cancer, with one study finding that survival in patients was poorer in patients with bone metastases, and another study finding that the development of bone metastases could predict subsequent development of metastasis in the brain.

Bone Metastases

Researchers at the Moffitt Cancer Center have created a computational model to simulate the bone metastasis process and to predict the outcomes of specific prostate cancer therapies.

This review will include discussion of the role of radiation therapy for osseous metastases and metastatic spinal cord compression, as well as the use of radiopharmaceuticals for painful osseous metastases.

As new data and new treatment options emerge, palliative radiotherapy algorithms will need to undergo continuous modifications and updates to ensure that patients receive optimal symptom relief.

Moving forward, perhaps no recent development in the use of RT in metastatic prostate cancer has captured greater attention than the use of radium-223 in metastatic castration-resistant prostate cancer (mCRPC).

In order to achieve maximum survival of patients with metastatic castration-resistant prostate cancer, the judicious use of all available effective agents and modalities is required. Both EBRT and radium-223 are effective at relieving pain, but both may decrease bone marrow function.

There is no question that radiopharmaceuticals have a role in the management of patients with metastatic bone disease. There is also no question that fractionated external beam radiotherapy (EBRT) is highly effective and generally well tolerated when delivered with large open or focal fields.

A palliative single-fraction radiation therapy is as good as multiple-fraction radiation therapy for pain relief from bone metastases. The single-fraction regimen is also less expensive.
