Egyptian Society of Liver Cancer Recommendation Guidelines for the Management of Hepatocellular Carcinoma.

Globally, hepatocellular carcinoma (HCC) is the fourth most common cause of death from cancer. The prevalence of this pathology, which has been on the rise in the last 30 years, has been predicted to continue increasing. HCC is the most common cause of cancer-related morbidity and mortality in Egypt and is also the most common cancer in males. Chronic liver diseases, including chronic hepatitis C, which is a primary health concern in Egypt, are considered major risk factors for HCC. However, HCC surveillance is recommended for patients with chronic hepatitis B virus (HBV) and liver cirrhosis; those above 40 with HBV but without cirrhosis; individuals with hepatitis D co-infection or a family history of HCC; and Nonalcoholic fatty liver disease (NAFLD) patients exhibiting significant fibrosis or cirrhosis. Several international guidelines aid physicians in the management of HCC. However, the availability and cost of diagnostic modalities and treatment options vary from one country to another. Therefore, the current guidelines aim to standardize the management of HCC in Egypt. The recommendations presented in this report represent the current management strategy at HCC treatment centers in Egypt. Recommendations were developed by an expert panel consisting of hepatologists, oncologists, gastroenterologists, surgeons, pathologists, and radiologists working under the umbrella of the Egyptian Society of Liver Cancer. The recommendations, which are based on the currently available local diagnostic aids and treatments in the country, include recommendations for future prospects.

The clinical impact of hepatitis C virus infection in Egyptian multiple myeloma patients.

BACKGROUND: Multiple myeloma (MM) is a human B cell neoplasia characterized by the clonal proliferation of malignant plasma cells in the bone marrow. Worldwide, hepatitis C virus (HCV) infection is a public health problem. For MM patients, the clinical impact of preexisting HCV infection is still unclear. We aim to assess the clinical characteristics and the prevalence of the HCV infection in Egyptian MM patients. This observational study included 81 MM patients. HCV antibody assay was performed, and positive cases were confirmed using a reverse transcription-quantitative PCR (RT-PCR) method. RESULTS: Fifteen (18.5%) patients were anti-HCV antibody positive. Only 6/15 (7.4%) patients were HCV RNA positive by RT-PCR. Liver affection in the form of hyperbilirubinemia with grade 4 adverse events was significantly higher in the anti-HCV positive/HCV RNA positive group versus anti HCV negative group (16.7% vs. 1.5%, p value = 0.005). The median HCV-RNA before the initiation of chemotherapy was 2.5 log IU/ml with mean ± SD = 4.25 ± 1.6 with no HCV reactivation. In the univariate and multivariate analysis, HCV infection was not an independent factor related to DFS. Low hemoglobin level < 10 g/dL (HR 0.59, 95% CI, 0.36-0.97, p value = 0.037) and abnormal serum total bilirubin level (HR 1.9, 95% CI 1.03-3.5, p value = 0.039) influenced DFS in the univariate analysis. However, in the multivariate analysis, serum calcium level greater than 12 mg/dL (HR 7.04, 95% CI 1.12-44.45, p value = 0.038) and abnormal serum total bilirubin level (HR 10.9, 95% CI 2.92-41.02, p value = < 0.001) remained statistically significant worse prognostic factors. CONCLUSION: In conclusion, our study revealed the prevalence of HCV infection in Egyptian MM patients. Serologic tests at diagnosis are necessary to identify these patients, and confirmation of positive cases by molecular techniques should be mandatory, with regular follow-up for liver dysfunction. Finally, further larger studies explaining the molecular mechanisms linking HCV and the MM pathogenesis are warranted.

OSSMAR: An Observational Study to Describe the Use of Sunitinib in Real-Life Practice for the Treatment of Metastatic Renal Cell Carcinoma.

PURPOSE: Sunitinib offers improved efficacy for patients with metastatic renal cell carcinoma (mRCC). To provide better disease management in the Middle East, we studied its use in mRCC in real-life practice in this region. MATERIAL AND METHODS: Patients diagnosed with mRCC and started on sunitinib between 2006 and 2016 from 10 centers in Africa and the Middle East region were studied in this regional, multicenter, observational, retrospective trial to obtain routine clinical practice data on the usage patterns and outcomes of sunitinib in mRCC in real-life practice. RESULTS: A total of 289 patients were enrolled. Median age at diagnosis was 58.7 years. The patient characteristics were as follows: 73.6% of patients were males; 85.8% had clear-cell renal cell carcinoma (RCC); 97.5% had unilateral RCC; 66.3% had metastatic disease at initial diagnosis; 56.3% received previous treatment for RCC, among which 98.7% had undergone surgery; and 15.2% and 31.4% were classified in the favorable and poor-risk groups (expanded Memorial Sloan Kettering Cancer Center criteria), respectively. On treatment initiation, the mean total sunitinib dose was 48.1 mg, and 87.6% of patients were started on a sunitinib dose of 50 mg. The mean duration of sunitinib treatment was 9.6 months. Overall response rate was 20.8%, with a median duration of 8.2 months. Median time to progression was 5.7 months. Median follow-up time was 7.8 months. By months 12 and 24, 34.3% and 11.4% of patients, respectively, were still alive. Seventy-six patients (60.9%) experienced 314 adverse events. Twenty-three patients (8.0%) experienced 28 serious adverse events. Overall, 83 patients (28.7%) discontinued their sunitinib treatment. CONCLUSION: The results are indicative of the general treatment outcomes of patients with mRCC in the Middle East using sunitinib in routine clinical practice. Reported adverse events are similar to those described in the literature but at lower frequencies.

Safety of Vinflunine in Patients with Advanced Urothelial Carcinoma Refractory to Platinum-based Chemotherapy: A Prospective Pilot Study.

BACKGROUND: Several single chemotherapeutic agents have been evaluated as the second-line treatment of advanced urothelial carcinoma. Despite encouraging efficacy outcomes, toxicity has often led to dose modifications or discontinuation. We aimed to assess the safety of vinflunine in a particular population of advanced transitional cell carcinoma of urothelium (TCCU), that were exposed to the previous toxicity of chemotherapy. METHODS: This is an open-label, prospective, single-center pilot study to evaluate the response rate and safety profile of vinflunine in patients with advanced TCCU. It was planned to enroll 25 evaluable patients. Eligible patients are those with progressive disease after first-line platinum-based regimen for advanced or metastatic disease. RESULTS: The study was prematurely closed due to two sudden deaths that were judged by the review board as treatment-related. Only ten patients were evaluated and received at least one cycle of vinflunine. All but one were male and seven underwent radical surgery. Eight had a distant metastasis (mainly lung and/or liver). Disease control rate was 40%, four patients had a partial response with median duration of response of 3.5 months. The median overall survival was 3.2 months (95% CI:1.67- 4.73). There were three serious adverse events namely two sudden deaths and one grade 4 thrombocytopenia. Nine grade 3/4 adverse events occurred. The most common all-grade adverse events were fatigue (50%), constipation (40%) and vomiting (40%). Moreover, grade 3 fatigue occurred in 30% of patients. Only one patient, who achieved PR for 5 months, was fit to receive further cytotoxic chemotherapy. CONCLUSION: The activity of vinflunine in advanced urothelial carcinoma came at the expense of its safety. The use of vinflunine has to be limited to the selected group of patients. However, this is a single institute experience in a limited number of patients.

Diagnostic performance of 18F-FDG PET/contrast-enhanced CT versus contrast-enhanced CT alone for post-treatment detection of ovarian malignancy.

OBJECTIVE: The aim of this study was to evaluate the diagnostic performance of combined fluorine-18 fluorodeoxyglucose (F-FDG) PET/contrast-enhanced computed tomography (Ce-CT) in comparison with Ce-CT alone for the detection of residual/recurrent tumor after initial treatment of malignant ovarian tumors. PATIENTS AND METHODS: The study prospectively recruited 111 patients with a clinical suspicion of ovarian tumor recurrence. Each patient underwent F-FDG PET/computed tomography (CT) with low-dose CT, followed immediately by Ce-CT. Study-based analyses for a total of 136 scans were carried out. For each study, 11 subsites were assessed on a four-point score (score 0=definitely benign, score 1=probably benign, score 2=probably malignant, and score 3=definitely malignant). The subsites were collectively categorized into four groups: local tumor site, peritoneum, pelvi-abdominal lymph nodes, and other sites (e.g. liver, lung, bone, brain, etc). The final diagnosis of disease status was made on subsequent follow-up by conventional imaging (CT/MRI), F-FDG PET/CT, or histopathology whenever possible. RESULTS: Of the 136 studies evaluated, 97 (71%) studies had recurrent/residual disease and 39 (29%) studies were disease free on the basis of the final diagnosis. F-FDG PET/Ce-CT and Ce-CT had a sensitivity, specificity, negative predictive value, positive predictive value, and accuracy of 96 versus 84%, 92 versus 59%, 90 versus 59%, 97 versus 84%, and 95 versus 76%, respectively. F-FDG PET/Ce-CT was significantly more sensitive, specific, and accurate compared with Ce-CT, with P-values of 0.002, 0.001, and less than 0.0001, respectively. Site-based analyses also showed significant differences. CONCLUSION: CombinedF-FDG PET/Ce-CT significantly outperforms Ce-CT alone in the post-treatment detection of malignant ovarian tumors.

Multidisciplinary management of clear-cell renal cell carcinoma in Africa and the Middle East: current practice and recommendations for improvement.

The management of renal cell carcinoma (RCC) has evolved considerably in recent years. This report represents the consensus of 22 relevant medical specialists from Africa and the Middle East region engaged in the management of RCC. Partial or radical nephrectomy is the standard of care for most patients with localized RCC. It is essential that patients are followed up appropriately after surgery to enable local and distant relapses to be identified and treated promptly. The treatment of advanced/metastatic disease has changed dramatically with the introduction of targeted therapies. Follow-up of these patients enables therapy optimization and assessment of response to treatment. There was universal agreement on the importance of management of RCC by a multidisciplinary team supported by a multidisciplinary tumor board. Barriers hindering this approach were identified. These included lack of awareness of the benefits of multidisciplinary team role, poor communication among relevant disciplines, time constraints, and specifics of private practice. Other challenges include shortage of expert specialists as urologists and oncologists and lack of local management guidelines in some countries. Solutions were proposed and discussed. Medical educational initiatives and awareness activities were highlighted as keys to encouraging cooperation between specialties to improve patients' outcome. Establishing combined genitourinary cancer clinics and formal referral systems should encourage a culture of effective communication. Joining forces with professionals in peripheral areas and the private sector is likely to help standardize care. Sustained action will be required to ensure that all patients with RCC in the region benefit from up-to-date care.

Low-grade endometrial stromal sarcoma with intravenous extension to the heart.

Endometrial stromal sarcoma (ESS) is a rare neoplasm of uterine origin. Intracardiac metastasis from this tumor is extremely infrequent. This report describes a 24-year-old woman from Yemen who had irregular vaginal bleeding shortly after spontaneous abortion. She developed left-lower-limb swelling, diagnosed by duplex scanning and magnetic resonance imaging as deep venous thrombosis in the inferior vena cava (IVC) that extended into the iliac veins on both sides, as well as the left femoral vein and right atrium. She developed acute respiratory distress, from which she recovered after transfer to the intensive care unit. Transesophageal echocardiography showed a large mass occupying the right atrium and ventricle and another mass in the right ventricular outflow tract with areas of cavitations. The tumor appeared to come from the IVC and extended through the right atrium and right ventricle into the pulmonary artery, ending in several digit-like projections. After surgical resection of the intracardiac mass, pathologic examination revealed a low-grade ESS that was confirmed by immunohistochemistry. The patient underwent panhysterectomy and IVC debridement. Pathologic examination revealed infiltrating low-grade endometrial sarcoma invading the myometrium and left adnexa, with intravenous extension into the pelvic veins and the IVC to the right side of the heart. This case shows that despite its well-known good prognostic nature, low-grade ESS may behave as an aggressive malignancy.
