Etiology of hepatocellular carcinoma in West Africa, a case-control study.

Hepatocellular carcinoma (HCC) is a leading cause of cancer in West Africa where HBV infection is endemic. However, limited information is available on other risk factors such as alcohol use, HCV and HIV infection. A case-control study was conducted in referral hospitals of Abidjan (Cote d'Ivoire), Bamako (Mali) and Lome (Togo). Cases were matched with controls on age, gender and participating site. The diagnosis of HCC relied on the combination of one or more space-occupying lesions suggestive of an HCC on a standardized abdominal ultrasound and an α-fetoprotein level ≥400 ng/ml. HIV, HBV and HCV serology were performed. Hazardous alcohol use was assessed using the AUDIT questionnaire. A conditional logistic regression model was used to measure odds ratio (OR) with their 95% confidence intervals (CI). A total of 160 cases and 320 controls were included. Cases were predominantly men (80.0%) with a median age of 47 years (IQR 38-57). Hazardous alcohol use (OR = 4.5 [CI 1.1-18.5]), HBV infection (OR = 62.5 [CI 20.5-190.7]) and HCV infection OR = 35.9 [CI 10.0-130.3]) were independently associated with HCC. Combining the effect of HBV infection and alcohol, HBV-infected hazardous drinkers had an OR = 149.8 (CI 13.5-1 667.0), HBV mono-infected had an OR = 57.4 (CI 18.8-175.3) (ref: HBV-negative). Aside the independent association of alcohol use and HBV and HCV infection with HCC, a synergic effect between alcohol use and HBV infection was identified. Timely screening and care of HBV infection and hazardous drinking might prevent a significant number of HCC in West Africa.

Factors Associated With Esophagus Cancers in Togo, Sub-Saharan Africa.

Background: Esophagus cancer is cancer of poor prognosis, of often late diagnosis. The objective of this study was to describe the factors associated with esophagus cancers in the Togolese population. Methods: It was a retrospective descriptive, cross-sectional study, on esophagus cancers histologically diagnosed at the Pathological Laboratory of Lomé over a period of 31 years (1990-2021). Results: We have collected 144 cases of esophagus cancer. The average age of patients was 57 ± 12 years, and the sex ratio was 2.34. The most applicant service was the service of Hepato Gastroenterology of CHU Campus (30.6%). Alcohol (57.6%), tobacco (45.8%) were the most present risk factors. Biopsies were the most addressed (97.2%). The average duration of symptom evolution was 6.42 months and the main symptom at the time of diagnosis was dysphagia (36.8%). The location of cancer was the lower third for 71.5% of cases. At histology, epidermoid carcinoma was the dominant type (90.3%). Male sex was statistically associated with the occurrence of epidermoid carcinoma and female sex with the occurrence of adenocarcinoma (P < .001). Alcohol, smoking, and consumption of hot foods were statistically associated with the occurrence of epidermoid carcinoma in this study (P < .05). Conclusion: Esophagus cancer remains a serious condition for late diagnosis. These are mainly epidermoid carcinomas and having alcohol and tobacco as risk factors. The awareness of the population on the main risk factors would reduce the incidence of oesophagus cancers within the Togolese population.

Excision of a Large Gastrointestinal Stromal Tumour Following 16 Months of Neoadjuvant Therapy with Imatinib (Case Report).

INTRODUCTION: Although the standard treatment for stromal tumours is surgery, in locally advanced forms, it is often necessary to achieve tumour downstaging to improve surgical outcomes. Neoadjuvant treatment in gastrointestinal stromal tumours (GISTs) with tyrosine kinase inhibitors, including imatinib, has been shown to be effective in several studies, but the duration of this treatment is still a subject of debate. CASE REPORT: We report a case of a large GIST of the stomach in a 51-year-old patient with atypical presentation that was initially unresectable. Neoadjuvant treatment with imatinib for 16 months resulted in a good response, allowing secondary surgical excision. CONCLUSION: Imatinib in neoadjuvant therapy should be continued as long as there is a good response and tolerance to the medication to obtain tumour downsizing compatible with carcinologic excision.

DIGESTIVE DISEASES IN ELDERLY AND FACTORS ASSOCIATED WITH LENGTH OF STAY IN THE HEPATOLOGY AND GASTROENTEROLOGY UNIT OF THE CAMPUS TEACHING HOSPITAL OF LOME (TOGO).

BACKGROUND: The digestive pathologies are frequent in the elderly and often have a latent and atypical symptomatology. OBJECTIVE: To assess the epidemiological and evolutionary current data on digestive diseases in the elderly, and look for factors associated with length of hospital stay. METHODS: Retrospective study of 10 years, including patients aged 60 and over hospitalized for digestive diseases in the Gastroenterology Department of the Campus Teaching Hospital of Lome, Togo. RESULTS: Of 5933 hospitalized patients, there were 1054 patients (17.8%) aged 60 years and over with a digestive pathology (526 men and 528 women). The average age was 69.5 years ±7.9 ranging from 60 to 105 years. The average length of hospital stay was 7.45 days ±6.2 ranging from 1 to 44 days. HIV prevalence was 2.4%. In order of decreasing frequency, there were hepatobiliary pathologies (54.3%) with a predominance of cirrhosis and liver cancer, eso-gastroduodenal pathologies (23.1%) with predominance of ulcers, gastric cancer and esophageal cancer, intestinal pathologies (8.7%) with a predominance of food poisoning, pancreatic pathologies (4.2%) with a predominance of pancreatic cancer and peritoneal pathologies (1.4%). Gastric cancer was the second digestive cancer found after liver cancer. Pancreatic head cancer was the second disease after gastric cancer which need a transfer in a surgical ward (P=0.031). There were 204 deaths (19.4%). The longest duration of hospitalization was due to gastric cancer (9.16 days). CONCLUSION: Hepatobiliary diseases were the most frequent and associated with a high death rate and a long hospital stay.

Descriptive Epidemiology of Cancers in Togo from 2009 to 2016

Background: Cancer is a global public health problem. According to World Report on Cancer in 2000, developing countries are becoming increasingly affected. Methods: This retrospective and descriptive 8-year study of all histological confirmed cancers was conducted using data from the anatomical pathology laboratory registry of Togo's only laboratory. The parameters were frequency, site and histological type as well as age and gender. Results: We found 1,738 cancers in patients aged from 4 months to 109 years (mean, 50.4 ± 4. The sex ratio (M/F) was 1.3. The most frequent localizations of the cancers were the prostate (10.3%) followed by the breast (9.9%), the stomach (8.4%) and the cervix (7.2%). In women, the median age was 47.4 ± 2.9 years, and the most common cancers were breast cancer (21.2%), followed by cervical cancer (16.3%). In men, the median age was 53.2 ± 7.3 years and the most frequent cancers were prostate cancer (18.5%), non-Hodgkin's lymphoma (13.2%) and stomach cancer (10.7%). In children, Burkitt's lymphoma (41.8%), retinoblastoma (11.6%) and nephroblastoma (9.6%) were the most important cancers. Conclusion: Cancers are frequent in Togo, those of the prostate, breast and cervix being most important with a worse prognosis. Emphasis should be placed on early detection and diagnosis.

RESUMO CONTEXTO: As patologias digestivas são frequentes no idoso e têm geralmente uma sintomatologia latente e atípica. OBJETIVO: Avaliar os dados epidemiológicos e de evolução sobre as doenças digestivas nos idosos, e procurar fatores associados ao período de permanência hospitalar. MÉTODOS: Estudo retrospectivo de 10 anos, incluindo pacientes com idades de 60 ou mais, hospitalizados para doenças digestivas no Departamento de Gastroenterologia do Hospital Universitário de Ensino de Lomé, Togo. RESULTADOS: De 5933 pacientes hospitalizados, havia 1054 pacientes (17,8%) com idade de 60 anos ou mais com uma patologia digestiva (526 homens e 528 mulheres). A idade média foi de 69,5 anos ± 7,9 variando de 60 a 105 anos. A duração média da estadia hospitalar foi de 7,45 dias ±6,2 variando de 1 a 44 dias. A prevalência do HIV foi de 2,4%. Em ordem de diminuição da frequência, houve patologias hepatobiliares (54,3%) com predominância de cirrose e câncer hepático, patologias do esôfago-gastroduodenal (23,1%) com predominância de úlceras, câncer gástrico e câncer esofágico, patologias intestinais (8,7%) com predominância de intoxicação alimentar, patologias pancreáticas (4,2%) com predominância de câncer pancreático e patologia peritoneal (1,4%). O câncer gástrico foi o segundo câncer digestivo encontrado após o câncer de fígado. Câncer de cabeça pancreática foi a segunda doença após o câncer gástrico, que necessitou transferência para a enfermaria cirúrgica (P=0,31). Houve 204 mortes (19,4%). A maior duração da internação foi devido ao câncer gástrico (9,16 dias). CONCLUSÃO: As doenças hepatobiliares foram as mais frequentes e associadas a uma elevada taxa de mortalidade e a uma longa estadia hospitalar.
