Filter by:As mentioned above, several prior studies have shown the positive effects of oral use of aloe vera juice in managing chemotherapy and radiation-induced oral mucositis and esophagitis. This study aims to add to the existing body of research around aloe vera juice and its effects on oral mucositis and esophagitis. The intention is to determine whether aloe vera juice should be considered as part of standard treatment.
This is an observational case-control study to train and validate a genome-wide methylome enrichment platform to detect multiple cancer types and to differentiate amongst cancer types. The cancers included in this study are brain, breast, bladder, cervical, colorectal, endometrial, esophageal, gastric, head and neck, hepatobiliary, leukemia, lung, lymphoma, multiple myeloma, ovarian, pancreatic, prostate, renal, sarcoma, and thyroid. These cancers were selected based on their prevalence and mortality to maximize impact on clinical care. Additionally, the ability of the whole-genome methylome enrichment platform to detect minimal residual disease after completion of cancer treatment and to detect relapse prior to clinical presentation will be evaluated in four cancer types (breast, colorectal, lung, prostate). These cancers were selected based on the existing clinical landscape and treatment availability.
The primary objective is to compare PD-1 inhibitor combined with preoperative chemoradiotherapy followed by surgery versus neo-adjuvant chemoradiotherapy followed by surgery, in terms of the overall survival time (OS) in patients with Stage T1-4aN1-3M0 or T3-4aN0M0 squamous cell esophageal carcinoma.
Currently, both the subtotal stomach and narrow gastric tube approaches are widely used for esophagogastric anastomosis after esophagectomy. Some stud- ies have concluded that the subtotal gastric conduit is superior to the wide gastric-tube approach, as it provides better protection of the submucosal vessels and can slightly increase gastric capacity. Furthermore, blood perfusion significantly decreases after tubular gastric surgery.
Comparison of nutritional and early surgical outcome between early and delayed oral feeding after esophagectomy for esophageal cancer
Patients diagnosed with esophageal cancer have difficulty eating, as the food pipe becomes obstructed by the cancer. This may impair the ability for the patient to receive appropriate calorie intake, especially during administration of chemotherapy and radiation therapy given prior to surgical resection. A strategy is to place a feeding tube directly in the stomach or in the small bowel to have an access to the patient's gastrointestinal tract during administration of chemo radiation therapy. However, these feeding tubes may lead to adverse events, including dislodgement, infection, the tube may be plugged, etc. If these complications were to happen, patients may have their treatment delayed, may have to come to the emergency department or even be admitted. In some cases, patients may need to have a surgery performed to treat the complication. Most centres in Canada have moved away from placement of these feeding tubes due to the high incidence of complications associated with the feeding tubes placement, and due to the high efficacy from the chemoradiation therapy in shrinking the tumour, allowing for the patient to swallow. In London, the preference from the Medical and Radiation Oncologists was to have these feeding tubes placed to avoid delay in treating the patients. There is therefore significant controversy as to what is the best approach in this patient population. Our goal is to run a feasibility randomized controlled trial studying this question.
Study of NGM438 as Monotherapy and in Combination with Pembrolizumab in Advanced or Metastatic Solid Tumors
Incurable oesophageal cancer remains a global problem and in South Africa the vast majority of patients with oesophageal cancer have advanced disease at first presentation and are not curable. Likely the most distressing symptom of advanced cancer in the oesophagus is dysphagia, which is the inability to swallow solids and later also liquids. This is successfully addressed in most cases by the placement of a stent in the oesophagus which opens the area of obstruction. When placed in the lower oesophagus, one of the major drawbacks of these stents is that they disrupt the anti-reflux mechanism of the oesophago-gastric junction, which can result in severe acid reflux, severely impacting the quality of life of the patient. To address this problem, a range of approved anti-reflux stents have been developed and tested in numerous trials. To date, the evidence is conflicting and there is insufficient current evidence to support the routine use of these stents. However, the trials are not all similar in how the acid reflux was measured or what type of stent was used. Furthermore, the use of anti-reflux medication, such as proton pump inhibitors, which may help reduce reflux, are not standardised across the trials and make further conclusions about these stents difficult to interpret. No data from Sub-Saharan Africa on the use of anti-reflux stents in these patients is available. South Africa faces a large burden of incurable oesophageal cancer and improving the quality of life of these patients is of paramount importance. This randomised controlled trial aims to investigate whether anti-reflux stents do indeed reduce acid reflux in patients with incurable oesophageal cancer compared to conventional oesophageal stents that do not have such an anti-reflux mechanism. Reflux will be measured using patient questionnaires about reflux, and other quality of life parameters, and will also be objectively measured using oesophageal scintigraphy, which has not been used in previous similar trials.
Rationale: Esophageal cancer and gastric cancer are among the top ten most common cancers worldwide. Both diseases have major impact on the nutritional status of patients and their quality of life. Studies investigating post-operative nutritional status are limited and postoperative identification and treatment of micro- and macronutritional deficiencies are currently lacking in (inter-)national guidelines. Objective: To identify and target vitamin deficiencies after surgery for esophagogastric neoplasms. Study design: Single centre intervention study. Study population: Patients aged 18 years and older that underwent esophagectomy or (sub- )total gastrectomy for esophagogastric neoplasms. Intervention (if applicable): Two tailormade supplements for patients; one for that underwent esophagectomy and one for (sub-)total gastrectomy. Main study parameters/endpoints: Baseline micronutrient deficiency measurements and after 6, 12, 24 months supplementation,. Secondary study parameters/ endpoints: Occurrence of exocrine pancreatic insufficiency (n,%), occurrence of diarrhoea (n,%), steatorrhea (n,%), bloating (n,%), time between surgery and start of supplementation (mean in months), quality of life experienced (questionnaires) at baseline and after 6, 12, 24 months supplementation. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: In this study, no health-related risks are present for participants due to the administration of supplementation that is already used as in clinical practice.
Rationale: The optimal technique for removal of visible dysplastic lesions in Barrett's esophagus remains controversial. Endoscopic mucosal resection (EMR) is safe, effective, easy to apply, and has been the most widely used technique since 2008. Endoscopic submucosal dissection (ESD) is a more controlled dissection method with potential improved efficacy, but at the cost of higher technical complexity. Objective: The investigators aim to compare EMR and ESD for removal of visible lesions in Barrett's esophagus. Study design: Randomized clinical trial Study population: Patients with Barrett's esophagus and a visible lesion with dysplasia and/or early cancer. Suspicion for submucosal invasion is an exclusion criterion. Intervention: Patients are randomized to receive either EMR or ESD, with follow-up and no ablation during 12 months after the resection. Main study endpoint: Primary endpoint is the proportion of patients with no evidence of residual or local recurrent neoplasia during 12 months follow-up after baseline.
