Background The aim of this prospective study was to evaluate the correlation of primary tumor metabolic activity parameters; maximum standardized uptake value (SUVmax) and tumor SUVmax/liver average SUV ratio (TLR) with clinical, histopathological and molecular characteristics of initial staging breast cancer (BC) patients using 18F-fluorodeoxyglucose (FDG) positron emission tomography / computerized tomography (PET/CT) scan. Results Forty female patients with newly diagnosed BC were enrolled in our study, age ranging from 31-78 years (mean 50.5 +/- SD11.7). All the primary tumors were detected with mean SUVmax 10.8(+/-SD 7.9). The mean /median SUVmax values of primary tumor was higher in premenopausal , stage III and IV, Estrogen Receptors negative( ER-), Progesterone Receptors negative(PR-), Human epidermal growth factor receptor 2 positive ( Her2neu+) patients, high nuclear grade (GIII), triple negative molecular subgroup (TN) and positive axillary lymph node (ALNs) metastasis,(P= 0.003, 0.017, 0.113, 0.089 0.01 ,0.002 , 0.007 and 0.016 respectively). The mean/median TLR values was higher in premenopausal ,Her2neu+, GIII, TN molecular subtype patients, stage III and IV and in patients with positive ALNs , ER- and PR - patients (P= 0.002, 0.0476 , 0.005 , 0.018 , 0.039 and 0.022, 0.095 and 0.129 respectively). SUVmax of the primary lesion and TLR were moderately negatively correlated with the age of the patients (P= 0.005 and 0.008 respectively), also they were moderately positively correlated with the size of the primary tumor (P= 0.019 and 0.036 respectively). TLR was predictive of nodal involvement AUC= 0.612 (95% CI: 0.431-792). The overall sensitivity and specificity of PET/CT for axillary staging was 100 % and 60 %, respectively (P= 0.006). Conclusion The SUVmax of the primary tumor and TLR values had similar significant associations with different prognostic factors in BC but only TLR can predict nodal involvement.
Background and objectives: Hepatocellular carcinoma (HCC) is the fifth most common malignancy and the third leading cause of cancer related mortality worldwide. The identification of new high-sensitivity and high-specificity markers for HCCis essential. Annexin A2 (ANXA2) plays an important role in the pathogenesis of multiple malignancies particularly HCCs and its expression strongly also affects the outcomes of HCC patients. This study aimed to investigate the clinical utility of hepatic and circulating Annexin A2 expression levels as a novel diagnostic marker of HCC and to correlate its level with alpha fetoprotein (AFP), the current marker ofHCC. Patients and methods: A total number of 40 patients(6 patients with chronic hepatitis, 8 patients with liver fiberosis, 6 patients with liver cirrhosis, 8 patients with early HCC and 12 patients with late HCC). The same number of age and sex matched healthy people was enrolled as a control group. All patients and controls were subjected to full medical history, complete medical examination abdominal sonography, laboratory investigations including liver function tests, AFP, platelet count, Prothrombin time and concentration, HBsAg, anti-HCV and serum HCV RNA quantitation by real time PCR. Liver biopsies were done for all patients. Evaluation of serum ANXA2 level for all patient and controlgroups was detected by using a human ANXA2 ELISA kit. Analyzing the ANXA2 expression at mRNA and protein levels was detected for patient groups by using RT-PCR by immunohistochemistry staining, respectively. Results: Serum ANXA2was significantly increased in all patient groups (except for chronic hepatitis group) compared to the control group (P<0.01). The serological evaluation and expression of ANXA2 levels were significantly increased in early HCC compared to serum AFP. ANXA2 expression was localized in both cell membrane and cytoplasm in HCC tissue, not detected in normal tissues and limited to some hepatocytes in chronic hepatitis patients. Over expression of ANXA2 mRNA levelwas present in HCC tissues compared to other patient groups (P<0.001). There was a significant relation with HCV infection, (P<0.001) when comparing ANXA2 values among positive and negative HCV RNA in HCC patients. No correlations were found between serum ANXA2 levels with serum AST,ALT, platelet count, INR and HBsAgin comparison to controls. Conclusion: Our results demonstrated increased levels of ANXA2 in both of tissues and sera of HCC patients and also in both AFP-positive and-negative cases. Results of serumANXA2 was concomitant with hepatic ANXA2 expression by RT-PCR and immunocytochemistry staining. Remarkably, Combination of conventional serum marker AFP with serumANXA2 may complement and benefit for early HCC detection.
Introduction: Sunitinib is a standard of care first line treatment for patients with metastatic renal cell carcinoma (RCC). Sunitinib standard dose is 50 mg once daily for 4 consecutive weeks followed by 2 weeks' off (4/2 schedule). Long-term and high exposure to this medication lead to severe adverse events (AEs); therefore, this trial was done to find the best schedule which gives the best outcome with minimal toxicity. Materials and methods: Seventy patients were randomly assigned into 2 groups, then received 50 mg/day of sunitinib. Group 1 (40 patients) received sunitinib for 4 consecutive weeks followed by 2 weeks off (4/2 schedule) while 30 patients were admitted to group 2 with 2 weeks on and 1 week off (2/1 schedule). Results: All patients (100%) had significantly higher AEs on schedule 4/2 vs. 73.3% on schedule 2/1 (p = 0.001). Furthermore, the grade 3 AEs on schedule 2/1 were significantly lower than those on schedule 4/2 (26.7% vs. 82.5%) respectively (p = 0.001), such as fatigue, diarrhea, hypertension, hand foot syndrome (HFS) and mucositis. Progression-free survival (PFS) rate was significantly higher in 2/1 schedule (60.9% vs. 38.6%) than in 4/2 schedule (p < 0.008). Multivariate analysis suggested that: age > 60 years, poor International Metastatic RCC Database Consortium (IMDC) risk category, tumor size > 10 cm and treatment schedule (group 1) were poor prognostic factors of PFS. Conclusions: Our study supported the use of 2/1 schedule of sunitinib in patients with metastatic RCC because of lower toxicity profile and better efficacy with improved PFS in comparison to 4/2 schedule.
Purpose Obesity is prevalent in Saudi Arabia and is associated with adverse clinical features and poor breast cancer (BC) outcomes. We determined the distribution of body mass index (BMI) and evaluated its association with disease characteristics and outcomes in women with non-metastatic BC. Patients and Methods We conducted a retrospective analysis of a prospectively collected database of consecutive patients treated for non-metastatic BC between 2002 and 2014. Patients were categorized into the following groups: underweight/normal weight (BMI <25 kg/m 2 ), overweight (BMI 25–29.9 kg/m 2 ), and obese (BMI ≥30 kg/m 2 ). Regression analysis was used to evaluate clinicopathological factors associated with BMI and clinical stage. Results A total of 2212 patients were enrolled. The median age was 45 years (interquartile range [IQR], 39–52 years), and the median BMI was 30 kg/m 2 (IQR, 26–34 kg/m 2 ). Most patients were premenopausal (63.6%), nearly half of the patients had stage III disease, and 11.2% were screen-detected. The prevalence of obesity was 53.4%, with a significant difference between the peri/premenopausal (49.4%) and postmenopausal (61.7%) groups (p < 0.001). Obese patients were more likely to be aged >40 years, be postmenopausal, have a history of oral contraceptive pills, have advanced-stage disease, and have undergone radiation therapy, and were less likely to have human epithelial growth factor 2 (HER2)+ disease than non-obese patients. Premenopausal obese women had fewer hormone receptor-positive and more triple-negative cancers than postmenopausal obese women did. Obesity, non-screening-detected BC, and HER+ status were independent prognostic factors for advanced-stage presentation. Conclusion The prevalence of obesity and its significant association with advanced BC justify the upscaling of screening services and instituting weight-reduction strategies.
