Volumetric Modulated Arc Therapy as an Example of the Advanced Capability of Modern Radiotherapy.

Background: Family physicians and internal medicine specialists play an essential role in treating cancer patients. Modern technological advances in radiotherapy are not widely appreciated by primary care physicians. Bone metastases are a frequent complication of cancer.

Modified Citrus Pectin as a Potential Sensitizer for Radiotherapy in Prostate Cancer.

Background: Radiotherapy is one of the primary therapies for localized prostatic carcinoma. Therefore, there is an emerging need to sensitize prostatic cancer cells to chemotherapy/radiotherapy. Modified citrus pectin (MCP) is an effective inhibitor of galectin-3 (Gal-3), which is correlated with tumor progression, proliferation, angiogenesis, and apoptosis.

Combined acetyl-11-keto-β-boswellic acid and radiation treatment inhibited glioblastoma tumor cells.

Glioblastoma multiforme (GBM) is the most common and most aggressive subtype of malignant gliomas. The current standard of care for newly diagnosed GBM patients involves maximal surgical debulking, followed by radiation therapy and temozolomide chemotherapy. Despite the advances in GBM therapy, its outcome remains poor with a median survival of less than two years.

Single-institution Experience of SBRT for Lung Metastases in Sarcoma Patients.

Objectives: Lung metastasectomy is regarded as the standard procedure for improving the prognosis of patients with metastatic sarcoma. Few reports are available in the literature describing the value of stereotactic body radiation therapy (SBRT) of lung metastases from primary sarcoma as an alternative to surgical treatment. We therefore sought to expand the evidence base for this modality.

AP-PA field orientation followed by IMRT reduces lung exposure in comparison to conventional 3D conformal and sole IMRT in centrally located lung tumors.

Little attention has been paid to the fact that intensity modulated radiation therapy (IMRT) techniques do not easily enable treatment with opposed beams. Three treatment plans (3 D conformal, IMRT, and combined (anterior-posterior-posterio-anterior (AP-PA) + IMRT) of 7 patients with centrally-located lung cancer were compared for exposure of lung, spinal cord and esophagus. Combined IMRT and AP-PA techniques offer better lung tissue sparing compared to plans predicated solely on IMRT for centrally-located lung tumors.
