Abstract

Neuronavigation is increasingly being used to assist in stereotactic neurosurgery due to its frameless property. In this study, we developed and assessed a modified method of performing stereotactic brain biopsies by combining the use of the Fisher stereotactic biopsy instrument, that was fixed on universal quick-lock holder, under infrared guidance of the BrainLab VectorVision Neuronavigation system. Eighteen patients received a frameless stereotactic procedure in this study, including 5 cases of brain biopsy, 2 cases of abscess aspiration, 10 cases of hematoma aspiration and one case of Ommaya reservoir implantation. All cases were on target and successful. In this paper, we present our technique, discuss the advantage and disadvantages of the method and review the literature.

Non-radical diagnostic biopsies do not negatively influence melanoma patient survival.

BACKGROUND: In fair-skinned Caucasian populations both the incidence and mortality rates of cutaneous melanoma have been increasing over the past decades. With adjuvant therapies still being under investigation, early detection is the only way to improve melanoma patient survival. The influence of incisional biopsies on melanoma patient survival has been discussed for many years. This study investigates both the influence of diagnostic biopsy type and the presence of residual tumor cells in the re-excision specimen on disease free and overall survival. METHODS: After (partial) removal of a pigmented skin lesion 471 patients were diagnosed with stage I/II melanoma and underwent re-excision and a sentinel node biopsy. All patients were followed prospectively, mean follow up >5 years. Patients were divided according to their diagnostic biopsy type (wide excision biopsy, narrow excision biopsy, excision biopsy with positive margins and incisional biopsy) and the presence of residual tumor cells in their re-excision specimen. Survival analysis was done using Cox's proportional hazard model adjusted for eight important confounders of melanoma patient survival. RESULTS: The diagnostic biopsy was wide in 279 patients, narrow in 109 patients, 52 patients underwent an excision biopsy with positive margins and 31 patients an incisional biopsy. In 41 patients residual tumor cells were present in the re-excision specimen. Both the diagnostic biopsy type and the presence of tumor cells in the re-excision specimen did not influence disease free and overall survival of melanoma patients. CONCLUSIONS: Non-radical diagnostic biopsies do not negatively influence melanoma patient survival.
