The use of fluorescent dyes and probes in surgical oncology.

Aims And Background: Improved visualization of surgical targets inside of the patient helps to improve radical resection of the tumor while sparing healthy surrounding tissue. In order to achieve an image, optical contrast must be generated by properties intrinsic to the tissue, or require the attachment of special visualization labels to the tumor. In this overview the current status of the clinical use of fluorescent dyes and probes are reviewed.

[Surgical treatment of tumor metastases in the lungs, brain or liver].

Metastases are generally an expression of widespread disease and therefore warrant systemic treatment. However, clinical observations have revealed that local surgical treatment might be beneficial in the case of organ-confined metastatic disease. Randomised studies have revealed that in the case of brain metastases, metastasectomy followed by radiotherapy, has a favourable outcome with respect to both the quality of life and overall survival.
