Prevalence of hepatitis B and C in patients with meningiomas and glioblastoma multiforme

The prevalence of hepatitis B and C in patients with glioblastoma multiforme or meningiomas has not been described. These infections are known to modulate the activity of the immune system, which potentially influences the development and course of cancer. We hypothesized that chronic hepatitis infection, which activates the immune system, decreases the risk of brain tumors, particularly those that are highly malignant. We performed a retrospective study to examine the prevalence of hepatitis B and C in patients with meningiomas and glioblastomas. The combined prevalence of hepatitis B and C in the USA from 1999–2008 was 5.7%. The prevalence of hepatitis B and C in patients with meningiomas was 2.4%; while among glioblastoma patients, the prevalence of hepatitis B and C was 1.38%. The odds ratio of having hepatitis B or C with glioblastoma versus meningiomas was 0.56, with a confidence interval of 0.19–1.6 and a P-value of 0.29. Compared with historical controls, the prevalence of hepatitis B and C in meningioma and glioblastoma patients was decreased. However, this difference may be attributed to the retrospective nature of our data and the natural history of hepatitis B and C infections. The prevalence of these viral infections was not statistically different in patients with meningiomas and glioblastomas. This suggests that hepatitis B and C primarily influence slow-growing, benign tumors and more aggressive cancers equally, if at all. To definitively test our hypothesis, future studies in which data are prospectively gathered are likely to be required.

Supratentorial primitive neuroectodermal tumor in an adult: a case report and review of the literature

Journal of Medical Case Reports
Supratentorial primitive neuroectodermal tumors predominantly occur in children, and are rare in the adult population. Less than 100 cases of supratentorial primitive neuroectodermal tumor have been reported in adults internationally. Our case study reports this rare incident.
A 22-year-old Hispanic man presented with headaches, blurry vision, diplopia, intermittent vomiting, and grossly decreased vision. A magnetic resonance image showed a left posterior parietal heterogeneously enhancing mass measuring 4.2cm × 7.2cm × 7.0cm. After craniotomy for resection and decompression, the mass was histologically revealed to be a supratentorial primitive neuroectodermal tumor. Standardized immunohistochemical studies for this mass were carried out.
We have concluded that immunohistochemical and genetic workup should be included in the standardized pathological workup for primitive neuroectodermal tumors in order to provide more prognostic information. Based on our current literature review, we propose an immunohistochemical panel.
