Clinical trials

In Portugal, approximately 2,424 new cases of head and neck cancer are diagnosed each year, of which 60% are already at an advanced stage, presenting with intense pain and dysphagia (difficulty swallowing). There is also marked social isolation due to communication difficulties, economic hardship, and facial disfigurement (altered facial appearance). As a result, patients frequently face challenges in accessing specialised palliative care services, encountering delays, fragmentation, or a complete absence of such care. The i-CARE-HN study is the solution: investigators aim to integrate outpatient palliative care with oncological treatment -namely chemoradiotherapy -at an earlier stage of the disease-when it is still limited to the throat and neck region, without metastasis (spread to other organs). This means multidisciplinary support from the outset of oncological treatment - symptom control, psychological support, and quality of life - without delaying the cure. It is like giving the patient a 'shield' against suffering, enabling them to complete treatment more efficiently. In the i-CARE-HN study, early palliative care aims to better manage patients' symptoms (such as pain, difficulty speaking, swallowing, breathing, dry mouth, loss of appetite, and anxiety), to clarify doubts, to support therapeutic decisions, and to strengthen communication between the patient and the team, without replacing the primary oncological treatment. Rather than waiting for symptoms to worsen before seeking help, this support will be provided throughout treatment with chemotherapy and radiotherapy. Through this simultaneous integration of outpatient palliative care into oncological treatment, investigators hope to improve patients' symptoms and quality of life, as well as clinical outcomes: fewer treatment interruptions, improved treatment tolerability, fewer emergency hospitalisations, and greater overall survival. Investigators will want to know how patients are feeling throughout the process, and to that end, will invite them to complete a survey at several points during the study. Responses to the questionnaires are critical to enabling the medical team to rapidly identify which participating patients present with the most significant symptoms and the greatest risk of complications. This study plans to recruit 64 patients aged 18 years or older, with a recent diagnosis of locally advanced, inoperable cancer, being followed on an outpatient basis at the IPO de Coimbra, IPO do Porto, and ULS de Coimbra, who will be invited to participate in the study. Should the patient agree to participate, some baseline data will be collected, and patients will subsequently be randomly assigned to one of two groups: one group will receive isolated chemoradiotherapy (standard treatment: cisplatin 100 mg/m² every 3 weeks- days 1, 22, and 49- and daily radiotherapy 70 Gy in 35 fractions over 7 weeks) and the other group will receive chemoradiotherapy alongside palliative care, on an outpatient basis (access to palliative care consultations). Patients randomised to the standard treatment group (chemoradiotherapy without a structured early palliative care intervention) will not have palliative care appointments systematically scheduled. However, should a referral to palliative care be requested, the patient may be directed to that clinical department.

Gastric cancer is the fifth cause of cancer-related mortality worldwide. Gastric carcinogenesis involves the progression from premalignant conditions such as atrophic gastritis and intestinal metaplasia to premalignant lesions like dysplasia, and ultimately carcinoma. Most diagnoses of gastric cancer are made at advanced stages, with a five-year relative survival rate of 36%. Therefore, early detection of premalignant conditions and lesions is crucial, as it allows for timely surveillance and treatment, which can improve patient survival. Upper gastrointestinal endoscopy (UGE) is the first-line examination for diagnosing upper gastrointestinal tract pathology, particularly oncological conditions. The European Society of Gastrointestinal Endoscopy (ESGE) and the United European Gastroenterology (UEG) have established that UGE quality is a priority, identifying specific quality parameters, such as the duration of the procedure, which is the most extensively studied parameter. According to ESGE recommendations, all UGE reports should include the procedure time (goal: ≥90% of reports), which should be seven minutes or longer for surveillance of intestinal metaplasia. This time threshold follows a study that established a causal relationship between longer procedures (≥ seven minutes) and a higher detection rate of premalignant gastric conditions and lesions. Subsequent observational studies have generally shown that setting a minimum procedure time increases the detection rate of lesions. The definition of procedure time varies between studies, being described as the time from intubation to extubation, but also as the time for withdrawing the endoscope from the second portion of the duodenum (D2) to extubation, also known as withdrawal time. The hypothesis under study is that a better definition of the most appropriate time for a diagnostic UGE could standardize reports, improve malignant lesion detection rates, and reduce the rate of undiagnosed cancers, without any additional risk to patients. Existing studies have been retrospective or comparative between different temporal cohorts, with no prospective or randomised comparative studies, nor any studies comparing the two existing metrics. Therefore, the aim of this study is to evaluate the best metric for inspection time during a diagnostic and/or surveillance UGE, between total inspection time versus withdrawal time, for the identification of malignant lesions.
