Africa Guidelines for Hepatocellular Carcinoma Buildup Process.

PURPOSE: Hepatocellular carcinoma (HCC), the fourth most common cancer in Africa, has a dismal overall survival of only 3 months like in sub-Saharan Africa. This is affected by the low gross domestic product and human development index, absence of coherent guidelines, and other factors. METHODS: An open forum for HCC-experienced health care workers from Africa and the rest of the world was held in October 2021. Participants completed a survey to help assess the real-life access to screening, diagnoses, and treatment in the North and Southern Africa (NS), East and West Africa (EW), Central Africa (C), and the rest of the world. RESULTS: Of 461 participants from all relevant subspecialties, 372 were from Africa. Most African participants provided hepatitis B vaccination and treatment for hepatitis B and C. More than half of the participants use serum alpha-fetoprotein and ultrasound for surveillance. Only 20% reported using image-guided diagnostic liver biopsy. The Barcelona Clinic Liver Cancer is the most used staging system (52%). Liver transplant is available for only 28% of NS and 3% EW. C reported a significantly lower availability of resection. Availability of local therapy ranged from 94% in NS to 62% in C. Sorafenib is the most commonly used systemic therapy (66%). Only 12.9% reported access to other medications including immune checkpoint inhibitors. Besides 42% access to regorafenib in NS, second-line treatments were not provided. CONCLUSION: Similarities and differences in the care for patients with HCC in Africa are reported. This reconfirms the major gaps in access and availability especially in C and marginally less so in EW. This is a call for concerted multidisciplinary efforts to achieve and sustain a reduction in incidence and mortality from HCC in Africa.

Safety and Effectiveness of COVID-19 Vaccines: Results from a Cross-Sectional Survey among Staff, Workers and Students at an Egyptian University.

Mass vaccination is the most effective strategy against the spread of the COVID-19 pandemic. However, concerns about the vaccine's safety and effectiveness remain a huge obstacle to vaccine acceptance. The aim of the present study was to explore different COVID-19 vaccine outcomes, including the development of adverse events and/or COVID-19 infection following COVID-19 vaccination. A cross-sectional study was conducted by distributing an online survey targeting staff and students at the British university in Egypt. A total of 637 participants fully completed the survey. Of these, 609 (95.6%) participants received the COVID-19 vaccine. Only 12.6% of the total vaccinated participants reported COVID-19 infection after vaccination. Of these, only 2.8% reported having severe symptoms while 9.9% reported having no or mild symptoms. The most common side effects reported after the first vs. second dose were headache (36.3% vs. 14.6%), tiredness and fatigue (26.9% vs. 10.7), and fever (25.6% vs. 6.7%). In conclusion, the present study explored different COVID-19 vaccine outcomes where the overall incidence of side effects is higher after the first dose than after the second dose. There is a relationship between COVID-19 vaccines' side effects and gastrointestinal disorders, gender, and the type of COVID-19 vaccine. Post-vaccination symptoms were more frequently reported in women compared to men and more frequent with viral vector vaccines compared to other types. The effectiveness of different types of COVID-19 vaccines was confirmed by the lower incidence rate of post-vaccination COVID-19 infection.

An open-label phase I pilot study of continuous intrapleural infusion of escalated doses of methotrexate in malignant pleural mesothelioma.

OBJECTIVES: The aim of this study was to evaluate the toxicity from escalated methotrexate (MTX) doses infused intrapleural over 5 days and to determine pleural and systemic drug levels with this chemotherapeutic approach. PATIENTS AND METHODS: Five patients with malignant pleural mesothelioma were treated with 3 cycles of intrapleural MTX infused through a pigtail catheter inserted in the pleural space. MTX levels were estimated in the pleural fluid and serum once daily throughout the treatment cycles. Fourteen days between cycles were calculated from the last day of the previous one. The total dose for each cycle was infused over 5 days with simultaneous intravenous calcium folinate. The total cycle dose for the first, second, and third cycles were: 300, 501, and 750.5 mg/m, respectively. RESULTS: The mean serum MTX level was 1.72 µmole/L, whereas that of the pleural fluid was 503.224 µmole/L. The mean serum/pleural ratio was 0.00396, whereas the pleural/serum ratio was 396.21. No remarkable toxicity was observed in the 5 patients except for patient 1 who developed fluid leakage around the puncture site. Patient 2 developed grade I hepatotoxicity and both patients developed grade I pleuritic chest pain and dry irritative cough. CONCLUSIONS: This study demonstrates no grade II toxicity from 750.5 mg/m of MTX infused intrapleural over 5 days. This approach allows attaining MTX pleural levels that are 95 to 3000 times higher than systemic serum levels, with minimal toxicity. The results mandate performing this trial on a wider scale as a preliminary step for a formal phase II study.
