Evaluation of serum squamous cell carcinoma antigen as a novel biomarker for diagnosis of hepatocellular carcinoma in Egyptian patients.

BACKGROUND: Hepatocellular carcinoma (HCC) is the fifth most common malignancy in the world. In Egypt, HCC was reported to account for about 4.7% of chronic liver disease (CLD) patients. Squamous cell carcinoma antigen (SCCA) has been reported to be strongly expressed in HCC tissue hampering its extensive use in clinical practice. AIM: To evaluate the clinical usefulness of serum SCCA levels as a serological marker for early detection of HCC among high-risk patients compared to AFP. MATERIALS AND METHODS: The study comprised of three groups. Group A included 30 patients with CLD diagnosed based on clinical, laboratory, and ultrasonographical investigations; group B included 49 patients with HCC diagnostically confirmed by spiral CT, elevated alfafetoprotein (AFP), and/or liver biopsy; and group C, the control group, included 15 healthy subjects matched for age and sex. All groups were subjected to thorough history taking, full clinical examination, and laboratory investigations including liver functions, viral markers, and AFP and SCCA estimation using ELISA technique. RESULTS: This study revealed a highly significant difference between patients with HCC, CLD, and controls regarding serum SCCA levels (5.138 +/- 7.689, 1.133 +/- 0.516, and 0.787 +/- 0.432 ng/ml, respectively). SCCA level was persistently elevated in patients with HCC with normal AFP levels representing its useful role in early detection and follow-up of patients treated for HCC. The area under the curve (AUC) of SCCA was 0.869 (95% CI 0.783-0.929), the cut-off value was established at 1.5 ng/ml with sensitivity of 77.6% and specificity of 84.4%). The difference between AUC of SCCA and that of AFP was 0.09 which mounted statistical significance. CONCLUSIONS: SCCA could represent a useful tool as a marker for detection of HCC.

Isolation of a new triterpenoid saponin from the root of Anchusa Strigosa L., family Boraginaceae

It was isolated a new triterpenoidsaponin from the root of plant Anchusa Strigosa L. family Boraginaceae The plant Anchusa is widely spread in different places in Syria, and it is used in treatment of some diseases like oedema, and fever and pulmonary diseases. The isolation and purification procedures was performed using thin layer chromatography TLC and column chromatography CC and high performance liquid chromatography HPLC and by using the methods of nuclear magnetic resonance chromatography NMR it was determined the chemical structure of the aglycon as triterpenoid linked by glycoside bond with three sugar parts

Primary intraorbital meningioma and schwannoma--a rare association.

Primary intraorbital meningioma and Schwannoma are rare tumours. For them to occur concurrently, or one following soon after another should be considered a curiosity. We present a 40 year old male who reported with proptosis of the right eye and a meningioma was removed surgically. Within 3 months symptoms recurred and a schwannoma was removed at surgery from the same site. Interesting features of the lesion are presented and discussed.
