Oesophageal Cancer

Major visceral oncologic surgery is associated with high postoperative morbidity, prolonged hospitalization, delayed recovery, and reduced quality of life. Patients undergoing surgery of the pancreas, liver, bile ducts, stomach, or esophagus frequently present with reduced physical fitness, malnutrition, sarcopenia, and psychological distress, all of which may negatively affect surgical outcomes and rehabilitation. Although prehabilitation has shown potential to improve functional capacity before surgery, structured prehabilitation pathways are currently not routinely implemented in Austria, and the feasibility of digitally supported perioperative care pathways remains insufficiently evaluated. The aim of the Prehab2Rehab-OncoVis study is to evaluate the feasibility, acceptability, and safety of a multimodal, digitally supported prehabilitation intervention for patients undergoing major visceral oncologic surgery with curative intent. The study will additionally explore potential effects on clinical recovery, functional capacity, rehabilitation outcomes, and patient-reported outcomes across the perioperative pathway. Prehab2Rehab-OncoVis is designed as a prospective, single-arm feasibility cohort study conducted at the University Hospital Salzburg and the University Institute of Sports Medicine, Prevention and Rehabilitation, coordinated by the Paracelsus Medical University in cooperation with the Ludwig Boltzmann Institute for Rehabilitation Research and the Ludwig Boltzmann Institute for Digital Health and Prevention within the Prehab2Rehab consortium. Approximately 30 adult patients, with the possibility to include up to 50 participants if feasible, will be consecutively recruited. The intervention consists of a four-week multimodal prehabilitation program combining supervised exercise training, promotion of physical activity, nutritional counseling, psycho-oncological distress screening, and health literacy support. Digital tools will support the intervention throughout the perioperative pathway, including the HERO application (Das Herz Reha-Informationstool) for patient education and health literacy, aktivplan as a digital exercise planner and training diary, and the CAATS telecommunication platform for remote supervision and tele-prehabilitation sessions where appropriate. The exercise intervention includes supervised center-based sessions and, for participants with longer travel distances, a hybrid model combining center-based and tele-prehabilitation sessions. Nutritional counseling will follow current European Society for Clinical Nutrition and Metabolism (ESPEN) guidelines and includes screening for malnutrition risk. Psycho-oncological distress screening will follow recommendations of the German Cancer Society and includes referral to supportive care when clinically indicated. Participants will be assessed throughout the perioperative pathway, including at the beginning and end of prehabilitation (Prehabilitation Assessment 1 \[PRE1\] and Prehabilitation Assessment 2 \[PRE2\]), during hospitalization and rehabilitation, and at a three-month follow-up after surgery. Primary outcomes focus on feasibility, including recruitment and retention rates, adherence, fidelity, safety, data management feasibility, and acceptability and usability of the digital technologies. Secondary outcomes include clinical recovery indicators, postoperative complications, length of hospital and intensive care stay, functional independence, psychological well-being, quality of life, body composition, cardiorespiratory fitness, functional exercise capacity, and muscle strength. To contextualize outcomes, two historical comparator cohorts will be used: a local hospital cohort of patients who previously underwent similar surgery without prehabilitation, and a national rehabilitation cohort derived from routine rehabilitation datasets matched for diagnosis, sex, and age. The study is intended to generate feasibility data and preliminary estimates that may support the development of future adequately powered randomized controlled trials evaluating digitally supported prehabilitation and rehabilitation pathways in visceral oncologic surgery.

The RECapp study is a clinical trial evaluating a digital tool designed to support patients recovering from surgery for oesophageal or stomach cancer. The goal is to reduce symptoms and improve quality of life during recovery. Each year in Sweden, around 1,400 people are diagnosed with these cancers. Although more people are surviving thanks to better treatments, recovery after surgery is often long and challenging, with lasting physical and emotional effects. At the same time, healthcare systems are under pressure to provide long-term support. RECapp is a digital platform developed together with patients and healthcare professionals. It includes a mobile app for patients and a web portal for healthcare staff. Patients can track their symptoms, receive personalised self-care advice, and get guidance on when to contact healthcare. Healthcare providers can follow patients' progress remotely. In this study, 250 patients from across Sweden will take part. They will be randomly assigned to either standard care or standard care plus RECapp. Participants will be followed for six months after surgery, and their symptoms and quality of life will be regularly assessed through questionnaires. If RECapp proves effective, it could become part of future cancer care in Sweden-helping patients feel better supported while also making care more efficient.

This is an observational trial that will look at patients undergoing endoscopic ultrasound (EUS) in patients with oesophageal cancer and to determine the proportion of cases in which EUS changes disease management in these patients.

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.

Cancer is one of the leading causes of mortality worldwide and is responsible for an estimated 9.6 million deaths yearly. Cancer-related deaths can be reduced if patients are diagnosed and treated early. Delay in cancer diagnosis can occur at any point along the diagnostic spectrum, from the first observation of symptoms to the start of treatment. Diagnosing cancer when it is still at an early stage, before it has spread, gives surgery, radiotherapy and other treatments the best chance of working. Therefore, early diagnosis is the most important way to improve cancer outcomes.Most of the cancers usually presents with vague and non-alarming symptoms. Most individuals are diagnosed late when the cancer has already spread, and the prognosis is poor. There are over 200 different types of cancer that can cause many different signs and symptoms. Sometimes symptoms affect specific body areas, such as abdomen or skin. But signs can also be more general, and include weight loss, tiredness (fatigue) or unexplained pain. The type of symptoms varies from person to person. The major reasons for not presenting to the GP with symptoms such as these are "not wanting to waste the GP's time" and normalisation of these symptoms. The persistence of a symptom, social influence and awareness encourage help-seeking behaviours in primary care. However, few believe their symptom(s) might be a sign of cancer. Consequently, people might choose to self-manage their symptoms by using over-the-counter medication, and to seek advice from other sources, (pharmacists, family, internet), rather than a primary care physician. RATIONALE FOR CURRENT STUDY An early cancer diagnosis is essential for receiving treatment as early as possible to have the best chance for successful treatment. Early diagnosis of cancer can be challenging. Sometimes, the cancer symptoms resemble common illnesses and could resolve with the use of over-the-counter medications and other remedies until they become persistent or debilitating. The present study focuses on ten cancer forms: colon, oesophageal, stomach, liver, bladder, uterine, vulval, ovarian, endometrial and pancreatic. Patients diagnosed with the cancers mentioned above often report experiencing vague symptoms (such as abdominal or back pain, indigestion, feeling full etc). They often use over-the-counter medication to manage their symptoms before seeing a doctor. Information about how often and what products participants purchase (e.g. pain killers, digestive products and natural remedies) to care for these symptoms could help identify these cancers a few crucial weeks or months earlier and encourage people to seek help sooner from their doctors.

Some people with cancer suffer from muscle wasting, lose weight and feel tired. This process, termed cachexia, is a significant problem and can lead to a reduction in both quality and quantity of life. Cachexia is caused by interactions between the tumour and the patient. Historically, it was considered to be a purely end-stage phenomenon of advanced cancer, however, it is now known that early signs of cachexia can even influence the outcomes of patients with potentially curative pathology, including those planned for a surgical resection. This study aims to collect information, from patients who are at risk of cachexia, about body composition, physical activity, quality of life and the body's immune response to cancer. Previously these measures have been most frequently studied in isolation, or at one single time-point, and are therefore likely to give an incomplete picture. A more holistic characterisation of surgical patients at risk of cancer cachexia, across their treatments, is currently lacking. Participants with cancer will be recruited to the study from surgical services in the United Kingdom (UK). A small number of 'control' patients without cancer, who are undergoing surgery for a benign condition, will also be recruited for comparison. Those recruited will have their height and weight measured, answer questionnaires about quality of life, undergo assessment of their physical function and levels of activity, have blood taken to analyse markers of inflammation and have their body composition measured by a variety of methods. A subgroup of patients will also undergo an additional magnetic resonance imaging (MRI) scan of their abdomen and thighs. At the time of their operation, participants will also have small biopsies of muscle, fat, tumour and urine taken for biochemical analysis. Patients with cancer, will be asked to return for three follow up appointments during the year after their operation where these assessments will be repeated.

Cancer of the stomach and oesophagus is among the world's top five cancers. Survival rates are very poor as the disease presents late and early symptoms are non-specific. The study team has developed a non-invasive test for cancers of the stomach and oesophagus based on the detection of volatile organic compounds in exhaled breath. These compounds are known to be produced by both cancers as well as cancer associated bacteria within the gut. The proposed innovation is to improve the accuracy of this test by investigating whether simple metabolic substrates can increase the production of these volatile organic compounds by both the tumour and its associated bacteria.

This study is a multicenter, open-label, phase II clinical trial evaluating the combination of SSGJ-706 with standard therapy for advanced gastrointestinal tumors. Its objective is to assess the safety, tolerability, and antitumor activity of SSGJ-706 in combination with standard treatment.

Oesophageal cancer is a common cause of cancer death worldwide. Curative treatment involves chemotherapy and surgery but has significant risks. Therefore, patient selection and improving physical fitness to withstand such major treatment is important to reduce the risk of complications. Physical fitness is traditionally measured by a specialised exercise test called Cardiopulmonary exercise testing (CPET), which can take up to one hour and requires specialised staff and expensive equipment such as a graded exercise bike or treadmill. Seismofit is a small device (smaller than a smartphone) used to estimate fitness in patients in under three minutes while lying down at rest. It measures the vibrations generated by the heart and, together with patient height, weight, age, and gender, accurately estimates fitness using an algorithm developed in healthy patients. The device has never been tested in a large group of oesophageal cancer patients to see if it can be used to predict complications in patients undergoing cancer treatment. In this study, patients undergoing Oesophageal cancer treatment with chemotherapy or chemoradiotherapy and surgery will have Seismofit measurements at various points during their treatment to see if we can predict complications and hospital stay. Secondly, this study will also evaluate the accuracy of Seismofit compared to the gold standard CPET results in cancer patients.

This is a prospective, randomized, open-label, two-arm phase 2 trial that will evaluate whether the use of Pulsed Low-Dose-Rate radiation technique, as compared to standard radiation, is associated with reduced rates of clinically significant esophagitis during and following chemoradiation.

Oesophagectomy (surgery to remove a cancerous portion of the oesophagus or gullet) is the cornerstone of treating oesophageal cancer. In recent years, minimally invasive techniques, including robotic assisted oesophagectomy have been introduced. These techniques reduce stress on patients, reduce pain, reduce the length of stay in hospital after their operation, without compromising cancer outcomes (and in some cases improving cancer outcomes). Any surgery carries the risk of complications. One complication that may arise with oesophagectomy is an increase in chyle leaks. Chyle is a fluid produced by the body that helps transport nutrients from the bowel to the bloodstream to allow them to be absorbed and processed. One of the channels that transports chyle, the thoracic duct, is divided as part of an oesophagectomy. Although it is clipped to reduce the risk of chyle leak, this may still occur, in up to 25% of operations. If a chyle leak occurs, a drainage tube needs to remain in the chest for a number of days, there may be alterations in the use of feeding techniques, and in a small portion of cases, there may need to be an operation to stop a leak, or a procedure in the radiology department. The goal of this study is to see whether use of a different type of post-operative feed (medium chain triglyceride or MCT feeds) can reduce the rate of chyle leak. This is already used to treat chyle leaks, and the question is whether using this as the routine post-operative feed can reduce rates of chyle leakage.

Oesophageal Squamous Cell Carcinoma (OSCC) is a cancer of the food pipe that affects around 2000 patients in the UK every year. It is often detected at an advanced stage, resulting in poor survival (5-year survival less than 20%). Early detection can improve survival (5-year survival \>70%). Therefore, early detection is vital to improving survival. There are no national screening guidelines, and an endoscopy (A camera test to look at the food pipe) is the only available test to detect OSCC. Early detection of OSCC is challenging for many reasons. Firstly, early disease symptoms are non-specific, which patients often overlook. Secondly, 'Alarm' symptoms such as weight loss, difficulty swallowing or vomiting blood are signs of advanced stage. Lastly, endoscopy is an invasive test with associated risks and significant discomfort. The investigators propose to develop a breath test for patients with non-specific symptoms. Breath testing has the ideal characteristics for a triage test because it is non-invasive, simple to perform, cost-effective and highly acceptable to patients. The test is based on identifying volatile organic compounds (VOCs, small molecules) that are produced by the cancer and released in breath. The breath test will be offered by General Practitioners (GPs) to patients with non-specific symptoms. Those who test positive will be referred for an urgent camera test, and those who test negative can be reassured.

Radiotherapy improves locoregional control and survival of thoracic tumour patients. However, the associated exposure of normal tissues, often leads to side effects and possibly even reduces survival. Indeed, there is growing evidence that overall survival after radiotherapy for lung and oesophageal cancer is related to the radiation dose to heart and lungs. This suggests that thoracic radiotherapy causes mortality, which is currently not recognized as radiation-induced toxicity. So the question arises how to explain this treatment-related mortality. Interestingly, Ghobadi et al demonstrated in rats that thoracic irradiation can lead to pulmonary hypertension (PH). Histopathological analysis showed that radiation-induced PH closely resembles the pulmonary arterial hypertension (PAH) subtype. Moreover, in a clinical pilot study we confirmed early signs of PH including dose-dependent reductions in blood flow towards the lungs in radiotherapy patients. In general PH significantly affects survival. Moreover, the PAH subtype is the most-rapidly progressive and lethal subtype. However, medical treatment can significantly slow down PAH progression, providing opportunities for secondary prevention. Yet, hard evidence that radiation-induced PH is a clinically relevant phenomenon in patients treated for thoracic tumours, is lacking.

The purpose of this study is to assess the efficacy of modulated mid-frequency whole-body electromyostimulation (WB-EMS) combined with nutritional therapy in patients with gastrointestinal cancer.

The aim of the project is to demonstrate superior detection ratio of \[18F\]AlF-FAPI-74 PET/CT compared to \[18F\]FDG PET/CT or conventional imaging in treatment-naïve, newly diagnosed patients with oesophagogastric adenocarcinoma (clinical T1-4N0-3M0) and pancreatic ductal adenocarcinoma (clinical T1-4N0-2M0-1) and describe the clinical utility of \[18F\]AlF-FAPI-74 PET/CT in oncological patients with a clinically challenging situation.

This study is a prospective, open label, multi-centre phase 2 trial which assesses the efficacy and safety of standard dosing compared to extended dosing interval of nivolumab, atezolizumab or pembrolizumab in advanced/unresectable gastric/gastroesophageal junction/oesphageal adenocarcinomas with PDL1 CPS ≥5%, hepatocellular carcinoma andnon-small cell lung cancer with PDL1 TPS≥50% with no prior treatment. The investigators hypothesize that nivolumab, pembrolizumab and atezolizumab can be used efficiently at extended dosing intervals, compared to their approved labels with comparable clinical outcome.

Literature review/rationale for project * Oesophageal cancer is associated with a grim prognosis despite many advances in treatment. Oesophagectomy is a key component of the care of patients who are candidates for curative treatment, however it is associated with substantial morbidity. * Several studies have suggested that oesophagectomies performed at higher volume tertiary centres are associated with lower morbidity and mortality than lower volume centres, and this has prompted changes to policy in countries such as Great Britain, Canada and the Netherlands with regards to the centralisation of these cases. A higher volume centre within Australia is likely to perform 6 or more procedures per year. * Currently within Australia, centralisation on a large scale has not occurred. This has been limited in part by resource provision and geographical barriers. Therefore, oesophagectomies in Australia are still routinely performed in regional centres. However, there is a paucity of recent outcomes data from these centres. Aims/objectives * Retrospective review of oesophagectomies undertaken in a single regional centre in Tasmania, Australia over 10 years (January 2014 to December 2023) * Assess outcomes (long and short-term complications and mortality) and compare to morbidity and mortality rates from larger international centres

The primary objective of this study is to assess the feasibility of treatment with bintrafusp alfa combined with definitive chemoradiation (carboplatin, paclitaxel and radiation) in patients with squamous cell carcinoma of the esophagus or gastroesophageal junction.
