The ADAPTA Study: ADjuvant chemotherAPy After Curative Intent resecTion of Ampullary Cancer.
Ampullary AdenocarcinomaAmpullary adenocarcinoma (AAC) is a rare gastrointestinal cancer with varying survival rates, particularly the aggressive pancreatobiliary (PB) subtype. Adjuvant therapy benefits only PB and mixed subtype patients, while prospective studies are required for validation. A study proposes tailored adjuvant treatments (CAPOX for intestinal subtype, FOLFIRINOX for PB and mixed subtypes) based on histopathology to enhance survival, also exploring molecular sub-studies for deeper insights.

Public's Intended Uptake and Views on Organization of Esophageal Cancer Screening
Barrett EsophagusBarrett Adenocarcinoma1 moreRationale: Research on novel methods to screen for esophageal adenocarcinoma (EAC) has expanded. Insight into individuals' drivers and barriers to attend screening is essential to tailor a potential new screening policy to their preferences. Public preferences should also be considered on the organizational level to guarantee client-centered decision-making in the design of the screening process. Objective: This study will examine Dutch individuals' intended uptake of EAC screening, including factors that predict uptake, and their views on its organization. Study design: Cross-sectional population-based survey. Study population: Dutch individuals aged 45-75 years. The required sample size is 2088 and 8350 individuals will be invited based on an assumed participation rate of 25%. Methods: Eligible individuals will be selected from the Dutch population registry (BRP) using simple random sampling. Invitations will be sent by postal mail with participants being directed to a digital survey. Main study parameters/endpoints: The primary outcome of the study is the intended uptake of EAC screening (strong vs weak). Secondary study endpoints are the perceived need for consultation, perceived need for general education campaigns, acceptability of risk stratification scenarios, and acceptability of using health care resources for EAC screening. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Subjects will not directly benefit from participating in this study. Nonetheless, participating in this study is not associated with any healthcare risks and the burden for the subjects is very low. The survey has a low burdensome nature and will take approximately 15 to 20 minutes to complete. All data will be pseudonymized, refusal to fill out the survey or desire to withdraw from the study will not have any consequences for the invited subject.

Pancreatic Cancer Early Detection Program
Pancreatic CancerPancreas Cancer9 moreEarly detection testing is recommended for individuals at elevated risk for the development of Pancreatic Cancer. This Protocol will define sufficiently elevated risk as either equal to or greater than five times the general population risk, or five times the average risk (1.5%) of developing pancreatic cancer by age 70; that is a 7.5% lifetime risk. Our inclusion criteria has a strong focus on the risk for pancreatic cancer imparted by the presence of hereditary cancer genes, as well as by family history. Enrolled subjects will undergo Endoscopic Ultrasound (EUS) alternating with Magnetic Resonance Imaging (MRI), every six to 12 months, for up to 5 years.

Biospecimen Collection and Testing for the Prevalence of Anal Dysplasia and Anal Cancer in Patients...
Cervical AdenocarcinomaCervical Adenocarcinoma In Situ54 moreThis trial studies the prevalence of anal dysplasia and anal cancer in patients with cervical, vaginal, and vulvar dysplasia and cancer. Studying samples collected from patients in the laboratory may help doctors learn more about the human papillomavirus and how often anal cancer occurs in patients with cervix, vagina, or vulvar cancer.

Data Collection for Patients With Low Grade Ovarian or Peritoneal Tumors
Low Grade Ovarian Serous AdenocarcinomaMalignant Ovarian Neoplasm4 moreThis study collects information to maintain a database on patients with low-grade ovarian or peritoneal tumors. Collecting information about the type of cancer and treatment, as well as details about follow-up care, may help researchers learn and better understand these tumor types and help develop better treatments for them.

Primary Cervical Cancer Screening by Self-sampling HPV Test
Human Papillomavirus InfectionCervical Cancer18 moreCervical cancer seriously threatens women's health and HPV infection is the main cause of cervical cancer. Traditionally, Cervical cancer screening is based on cervical exfoliated cell samples collected by health care provider, which is labor consuming and the coverage and compliance are both relatively low in some areas. Non-invasive hrHPV self-sampling test appears to be more acceptable and may improve the HPV screening coverage. This study aims to evaluate the clinical performance of a newly developed urine/vaginal self-sampling hrHPV test in Cervical cancer screening.

Pre- and Post-operative TEG Indices in Patients With or Without Adenocarcinoma Undergoing Surgical...
Liver CancerEsophageal Cancer5 moreThe investigators hypothesize that abnormalities in thromboelastography (TEG) parameters in patients with liver, pancreas, biliary, esophageal, colorectal, and lung adenocarcinoma can serve as biomarkers for oncologic disease burden, cancer recurrence and overall survival as well as thrombotic and hemorrhagic post-operative complications. The investigators further hypothesize that there is histologic pathology correlates to pre-operative TEG abnormalities, and that it identifies patients with virulent tumor biology.

Improving the Intraoperative Diagnosis Accuracy of Invasiveness for Small-sized Lung Adenocarcinoma...
Lung AdenocarcinomaStage IThe goal of this observational study is to improve the intraoperative diagnosis accuracy of invasiveness for small-sized lung adenocarcinoma by combining multi-modal information. The main question it aims to answer is whether multi-modal information have great value of prediction on the invasiveness for small-sized lung adenocarcinoma. Since a promising limited resection is largely based on intraoperative frozen section diagnosis, there is a growing demand on the high-accuracy of timely pathology diagnosis. The multi-modal information of participants will be collected retrospectively.
