Popis: According to the US Center for Disease Control, cancer deaths are the second most common cause of mortality in both adults and children. Definitive treatment of solid tumors involves surgical resection with or without systemic chemotherapy and radiation. The advent of local drug delivery presents a unique treatment modality that can offer substantial benefits in cancer management. Local drug delivery offers targeted drug delivery to cancer tissues while minimizing side effects of the medications. Three main phases in solid tumor management exist for the treating physician: initial diagnosis with tissue biopsy, surgical resection with or without chemotherapy, and management of metastatic disease. Image guided studies, using modalities such as MRI, computerized tomography, and ultrasound to sample tumors have been described. The initial diagnosis phase offers a treatment window for local drug delivery with the aid of image guidance. After the diagnosis of malignancy is made, surgical resection can become an important part of tumor management. Currently, FDA approved local drug delivery systems are being used in concert with resection for intracranial glioma. Many other applications of implantation of local drug delivery at the time of surgery in other tumors, including breast and neuroblastoma, are being investigated. Finally, for patients who present with or progress to single sites of metastatic disease, such as brain or liver metastasis, studies have shown potential applications for local drug delivery as well. This review will discuss the current state of local drug delivery in the treatment of solid tumors and possible future directions.
