Oesophageal cancer is the seventh most common cancer and the sixth leading cause of cancer death worldwide, and its incidence varies globally. In Uganda, the incidence and trend are on the increase. ...However, there is a paucity of published data regarding this population's oesophageal cancer clinicopathologic characterisation and treatment outcomes.
To study the patients' clinicopathologic characteristics and treatment outcomes of oesophageal cancer over 10 years at the Uganda Cancer Institute.
Patients' charts with histologically confirmed diagnoses of oesophageal cancer for 2009-2019 were identified. Case information, which included patient demographics, history of alcohol use or smoking, tumour location, histological type, tumour grade, clinical TNM (Tumour, Node, Metastasis) staging treatment exposure and treatment outcomes, was evaluated retrospectively. The median survival time was estimated with the Kaplan-Meier method and the median follow-up period was estimated using the reverse Kaplan-Meier.
1,965 oesophageal cancer patients were identified; 1,380(70.23%) were males and 585(29.77 %) females, their mean age was 60.20 years (±12.66). Most males had a history of both alcohol consumption and smoking 640(46.38%). The lower third of the oesophagus was the most common anatomical location 771(39.24%). The majority had squamous cell carcinoma histological type 1,783(90.74%) followed by adenocarcinomas 182(9.26%) in the distal oesophagus. Poorly differentiated tumour grade 743(37.81%) was predominant. The majority of the patients were in stage IVB, 733(37.30%), and most patients were planned for the best supportive care, 731(37.20%). Radiation alone was offered to 621(31.60%) and feeding gastrostomy to 249(12.70%). Treatment outcomes: at the time of the current analysis, 58.68% had died, 1.48% were alive and 39.84% were lost to follow-up. The median follow-up period was 65 months (IQR:35.83-83.30) with a median survival time of 4.47 months (95% CI: 4.17-4.80).
Treatment outcomes of Ugandan oesophageal cancer patients seeking care are poor as most patients present with advanced disease. There is a significant loss of follow-up after treatment initiation. Therefore, reduction in exposure to known modifiable risk factors, early detection and timely referral for treatment strategies are needed to improve outcomes of these patients in our population. Designing interventions to improve treatment adherence is necessary.
Background: There is limited published data regarding the distribution of esophageal cancer patients by sub-regions, districtsand ethnicity in Uganda. Objectives: To study the distribution by ...sub-regions, districts, ethnicity and sub-regions post-care outcomes of esophagealcancer patients in care over ten years at the Uganda Cancer Institute. Methods: Patients’ charts with confirmed diagnoses of esophageal cancer for 2009-2019 were identified. Case information,which included demographics, clinical presentation, distribution by sub-regions, districts, ethnicity and sub-regions post-careoutcomes, were retrospectively abstracted. Results: Central 671(34.15%), Southwestern 308(15.67%), Elgon 176(8.95%) and East central 163(8.29%) sub-regions had mostpatients. Mostly from administrative districts of Wakiso 167(8.50%), Mbarara 51(2.59%), Tororo 53(2.70%), Busia 33(1.68). Baganda,Banyakole, Bagisu and Basoga ethnic groups predominate. Patients from neighbouring countries were mainly from Rwanda56(2.85%), South Sudan 24(1.22%), then Kenya 21(1.07%), and Rwandese, Dinka and Luo by ethnicity, respectively. Centraland Southwestern sub-regions had the most post-care outcomes of the patients regarding living, death, and loss to follow-up. Conclusion: Patients are commonly from the administrative districts of Central, Southwestern, Elgon and East Central sub-regionsand neighbouring countries of Rwanda, South Sudan and Kenya. Baganda, Banyakole, Bagisu and Basoga are the mainethnic groups. Central and Southwestern sub-regions are with most post-care outcomes.

There is a paucity of published data regarding the trend and distribution of gastrointestinal malignancies in Uganda.
To study the trend and distribution of gastrointestinal malignancies over a 10 ...year period at five regional referral hospitals in Uganda.
Patient's charts with histologically confirmed diagnoses of gastrointestinal malignancies for the period 2002-2011 were identified. Case information, which included age at diagnosis, sex, and year of diagnosis, primary anatomic site of the tumour and hospitals attended, was retrospectively abstracted. Patient's clinical and demographic features were compared.
Oesophageal cancer was the most common (28.8%) followed by liver (25.8%), stomach (18.4%) and colorectal (14.3%). The mean age at diagnosis for all the cancers was not significantly different in both sexes 54.1, (SD16.1) versus 53.6, (SD 14.7). The highest mean annual number of cases of oesophageal and stomach cancers was 21.8, (SD 15.5) and 16.6, (SD 13.0) respectively from Mbarara Hospital; Lacor had the highest mean annual number of liver cancer cases (21, SD 17.7) followed by Mbale (11.4, SD 8.3). The mean annual number of colorectal cancers was highest in Mbale Hospital (10.3, SD 8.1) followed by Lacor (4.9, SD 3.9). The distribution of oesophageal, liver, stomach and colorectal cancers diagnosed per year across the five referral hospitals was different, P<0.001.
Oesophageal, liver, stomach and colorectal cancer remain the most common gastrointestinal malignancies and their rate is increasing in Uganda. There is a need for awareness, endoscopic and radiological assessment of symptomatic individuals and a need for screening of high index patients.
There is a paucity of published data regarding upper gastrointestinal diseases in Ugandans with upper gastrointestinal symptoms referred for endoscopy.
To study the presenting complaints, pathology ...and Helicobacter pylori prevalence among patients with upper gastrointestinal symptoms in South-Western Uganda.
Patients presenting with upper gastrointestinal symptoms underwent upper endoscopy and a urease test for Helicobacter Pylori, all suspicious lesions were biopsied for histopathology review as appropriate.
The most common presenting complaints were epigastric pain (51.6%), dysphagia (13.6%) and odynophagia (7.1%). The most common endoscopy finding was gastritis (40.2%), followed by normal examination (15.2%), oesophageal cancer (13.6%), gastric ulcer (7.6%) and gastric cancer (7.1%). Patients older than 40 years (n=110) had significant findings including gastritis (50.9%), oesophageal cancer (22.7%) and gastric cancer (11.8%). However in younger patients, with the age range of 18-40 years (n=74), most examinations were normal (92.9%). Of the 176 patients able to undergo Helicobacter pylori testing 75.6% were positive. Helicobacter pylori infection was associated with statistically significant increase in gastritis, oesophageal cancer, gastric ulcer, gastric cancer, and duodenal ulcers (p-values< 0.05).
Gastritis, ulcerative disease, and upper gastrointestinal malignancies are common in South-Western Ugandans and are associated with a high prevalence of Helicobacter pylori.
