• Hepatic observation may be categorized differently depending on the imaging modality used. • We compared LI-RADS categorization between CT, MRI and combined CT/MRI. • MRI produces higher accuracy and sensitivity, while CT produces higher specificity. • Combining CT and MRI improves LIRADS categorization reports. • Considering additional cost, combined methodology could be restricted to challenging cases.

WB-MRI is more sensitive than F-FDG PET/CT in the diagnosis of MM before treatment; however,F-FDG PET/CT is more specific than WB-MRI in detecting residual involvement in treated patients.

Background:Due to lack of availability of gene expression profiling (GEP) for most developing countries and clinicians; the immunohistochemistry (IHC) is mostly used in the clinical application. The aim of our study is to check the possibility of using IHC to detect MYC and BCL2 in our patients with diffuse large B-cell lymphoma (DLBCL) instead of GEP to stratify them into high and low-risk groups. This will help in a proper treatment choice of subsequent improvement in the survival outcome.Method:During the study period, 90 DLBCL patients were eligible. MYC and BCL2 evaluated by IHC and gene rearrangement by real-time PCR (RT-PCR) and correlated with clinical-pathological features and survival.Results:Through IHC, the expression of MYC, BCL2, and double expression was detected in 35.6%, 46.7% and 30% of patients, respectively. While by RT-PCR, it was 4.53±0.74 for MYC compared with 2.18±0.78 for BCL-2. Most patients with BCL2+/MYC+; double-expressor and double-hit lymphomas (DEL and DHL) had high stage (III, IV), more extra-nodal involvement, (P value <0.001) and intermediate to high International Prognostic Index (IPI) risk profile (P-value <0.001). The median overall survival was 14 months and 6 months for DEL and DHL, respectively. While all patients with DHL died during the follow-up period, the median PFS were only 2 months for DEL. There was a statistically significant correlation between mRNA of MYC and BCL2 with their protein expression (p<0.001).Conclusion:Our results confirmed the unique characters and poor outcome associated with DEL and DHL mandated the need for more intense therapy and not the standard protocol. Moreover, the significant correlation between protein overexpression and gene rearrangement may open the door for the possibility to use IHC instead of RT-PCR in developing countries.

Objectives: Serous ovarian carcinoma (SOC) is the commonest ovarian carcinoma type with poor prognosis due to early metastasis and first presentation with advanced stage. In this work, we investigated serum level of Galactin-1 (Gal-1) and its tissue immunohistochemical expression in SOC patients at different stages trying to find out its significance as a diagnostic and prognostic marker. Patients and methods: The study included 95 females I-Control group: Twenty five healthy females; II-Patients group: Seventy females diagnosed as SOC at different stages; Stage I: 8 cases, Stage II: 12 cases, Stage III: 32 cases and Stage VI:18 cases. Serum Galectin-1 and CA-125 were measured by ELIZA and tissue Galectin-1 was assessed by immunohistochemistry. All patients were followed for up to 3 years after surgery. Results: Serum Gal-1 and CA-125 levels were significantly higehr in SOC patients compared to controls (p < 0.001). We found a direct positive statistically significant correlation between serum Gal-1 and CA125 levels (p < 0.001). Serum Gal-1 at cut off value > 135 ng/ml was superior to CA-125 a cut off value > 49 u/ml with sensitivity, specificity of 100%, vs 88.57, 96% for CA-125. Serum Gal-1 was significantly associated with tumor stage (p < 0.001). Immunohistochemistry showed that patients with strong Gal-1 expression had higher serum level (p = 0.002). Stromal and tumor Gal-1 expression were significantly correlated with tumor grade (p < 0.001) and stage (p = 0.001). Serum Gal-1, CA-125
