Surgery and chemotherapy have historically been the mainstay of treatment in patients with metastatic disease. However there are many alternative therapies available to relieve the symptoms and morbidity of metastases. In this paper, we review the role and highlight the advantages of minimally invasive techniques employed in patients with pulmonary and bone metastases.

BACKGROUND We have previously offered data suggesting a positive linkage of postoperative up-regulation of systemic angiogenic activity and postoperative progression of pulmonary metastasis in osteosarcoma. The finding that the significant down-regulation of endostatin was critical in angiogenic elevation after primary tumor removal suggests that endostatin is a candidate for antiangiogenic the...

Primary tracheal cancer is a well-known disease while metastases to the trachea from distant sites are exceedingly rare. We report a case of endotracheal metastasis from a colon cancer in a female, who underwent surgery for a sigmoid cancer with no metastases. Five years later, she was diagnosed with a solitary pulmonary metastasis and underwent a left lower lobectomy. After further two years, ...

The treatment of osteosarcoma pulmonary metastases remains a challenge. T cells genetically modified to express a chimeric antigen receptor (CAR), which recognizes a tumor-associated antigen, have shown activity against hematopoietic malignancies in clinical trials, but this requires the identification of a specific receptor on the tumor cell. In the current study, we found that interleukin (IL...

Previous studies have demonstrated that human malignancies can synthesize large amounts of thromboxane. It has also been reported that thromboxane can significantly alter multiple components of physiologic and immunologic function. We investigated the effect of elevated levels of thromboxane on host response to tumor using multiple rat models, and the long acting thromboxane analogue U-46619. A...
