40. Amplification of the Epidermal Growth Factor Receptor Gene in Biopsy Specimens from Human Intracranial Tumours

Author

Abstract

Amplification and overexpression of proto-oncogenes are associated with the malignant nature of some human tumours. In this study we have determined the prevalence of amplification of the proto-oncogenes c-erb Bl (= epidermal growth factor receptor gene), c-erb B2 and c-myc in 44 human intracranial tumours (27 gliomas, six metastases to the brain and 11 meningiomas). None of the tumours had an amplified c-erb B2 gene and only two tumours had an amplified c-myc gene. Nineteen per cent (five out of 27) of the gliomas, 50% (three out of six) of the brain metastases and 0% (0 out of 11) meningiomas had an amplified EGF-receptor gene. Amplification of the EGF-receptor gene appeared to give a growth advantage when single-cell suspensions of the tumours were grown in agarose.

Abstract

Objective: Eloquent diffuse low-grade gliomas (LGGs) threaten patients' neurologic function and are also associated with inferior survival. Many neurosurgeons still refrain from early resection due to the fear of iatrogenic neurologic injury. However, the perceived safety of expectant management strategies may soon be overshadowed by the progressive deficits of tumor growth in eloquent regions. It is also known that radical and successful surgery prolongs progression-free survival, overall survival, and may reduce seizure burden and also potentially neurocognitive functions. Thus early successful surgery with preservation of function has a significant impact on patients' health. In modern neurosurgery, safe resection is often possible with detailed knowledge of anatomy and function together with the active use of various intraoperative surgical tools. We present illustrative cases of eloquent LGGs treated with different intraoperative tools., Methods: An introduction to important intraoperative tools in LGG surgery is provided by experts in the field and described in five cases viewed in the context of the recent LGG literature., Results: We present five cases with presumed eloquently located LGGs where extensive resection was offered using different intraoperative techniques. The clinical and radiologic outcomes are described., Conclusions: Correct use of intraoperative tools together with the surgeon's knowledge of anatomy and function will provide good functional and oncologic results in eloquently located LGGs. Watchful waiting or deferral of surgery due to tumor location (i.e., claiming inoperability) is very rarely good practice., (Georg Thieme Verlag KG Stuttgart · New York.)

Abstract

Objective: The objective of this study was to investigate the clinical applicability of navigated blood flow imaging (BFI) in neurovascular applications. BFI is a new 2-dimensional ultrasound modality that offers angle-independent visualization of flow. When integrated with 3-dimensional (3D) navigation technology, BFI can be considered as a first step toward the ideal tool for surgical needs: a real-time, high-resolution, 3D visualization that properly portrays both vessel geometry and flow direction., Methods: A 3D model of the vascular tree was extracted from preoperative magnetic resonance angiographic data and used as a reference for intraoperative any-plane guided ultrasound acquisitions. A high-end ultrasound scanner was interconnected, and synchronized recordings of BFI and 3D navigation scenes were acquired. The potential of BFI as an intraoperative tool for flow visualization was evaluated in 3 cerebral aneurysms and 3 arteriovenous malformations., Results: The neurovascular flow direction was properly visualized in all cases using BFI. Navigation technology allowed for identification of the vessels of interest, despite the presence of brain shift. The surgeon found BFI to be very intuitive compared with conventional color Doppler methods. BFI allowed for quality control of sufficient flow in all distal arteries during aneurysm surgery and made it easier to discern between feeding arteries and draining veins during surgery for arteriovenous malformations., Conclusion: BFI seems to be a promising modality for neurovascular flow visualization that may provide the neurosurgeon with a valuable tool for safer surgical interventions. However, further work is needed to establish the clinical usefulness of the proposed imaging setup.
