Abstract

Radiation therapy is commonly used to alleviate the pain associated with bone metastases. This article reviews the components of the radiation oncology evaluation. The options for use of ionizing radiation including postoperative treatment, limited-volume external beam radiotherapy, wide-field radiotherapy, and radioisotope therapy are compared and contrasted. Side effects and toxicities of radiotherapy are discussed.

Hematometrocolpos in an adolescent female treated for pelvic Ewing sarcoma.

Radiation therapy is often used to achieve local control of pelvic Ewing sarcoma in children. The effects of radiation on the female reproductive tract have been well documented in adults with gynecological malignancies, but the long-term consequences of pelvic radiation in pre-pubertal or adolescent girls are not as well described. We report a case of hematometrocolpos developing in an adolescent previously treated with chemotherapy and radiation therapy for pelvic Ewing sarcoma. We describe the clinical presentation, radiographic features, gross pathology, treatment strategies, outcome, as well as putative predisposing factors and preventative interventions.

Kallikrein 4 is a potential mediator of cellular interactions between cancer cells and osteoblasts in metastatic prostate cancer.

BACKGROUND: Prostate cancer (PCa) and bone cell interactions are critical in the metastatic phase. Kallikrein 4 (KLK4/hK4) is expressed in both PCa and mineralized tissues. We determined if KLK4/hK4 expression was associated with, and influenced by, the bone environment of metastatic PCa. METHODS: Immunohistochemistry, in vitro co-culture, cell migration, and attachment assays. RESULTS: hK4 was localized to tumor cells and osteoblasts in bone metastases. KLK4/hK4 increased in LNCaP and PC3 cells co-cultured with SaOs2 cells; SaOs2 KLK4/hK4 was unchanged. Co-culture did not affect cell proliferation but altered alkaline phosphatase activity/mRNA levels in SaOs2 cells. KLK4-transfected PC3 cells had increased migration towards SaOs2 conditioned medium and greater attachment to the bone-matrix proteins, collagens I and IV. CONCLUSIONS: hK4 expression and interaction with both tumor cells and osteoblasts suggests a role for hK4 in PCa bone metastasis. Whether this observation is unique to bone metastasis or reflects a role for hK4 in PCa metastasis generally is yet to be established.
