Active clinical trials for "Carcinoma"

Chromosomal instability (CIN) refers to ongoing chromosome segregation errors throughout consecutive cell divisions. CIN is a hallmark of human cancer, and it is associated with poor prognosis, metastasis, and therapeutic resistance. Analyzing CIN of the DNA extracted from bile tract exfoliated cells in bile samples seems a promising method for diagnosing, monitoring, and predicting the prognosis of patients with malignant biliary obstruction, including biliary tract cancer (BTC), pancreatic head carcinoma. CIN can be assessed using experimental techniques such as bulk DNA sequencing, fluorescence in situ hybridization (FISH), or conventional karyotyping. However, these techniques are either time-consuming or non-specific. The investigators here intend to study whether a new method named Ultrasensitive Chromosomal Aneuploidy Detection (UCAD), which is based on low-coverage whole-genome sequencing, can be used to analyze CIN thus helping diagnose malignant biliary obstruction and assessing follow-up.

Hepatocellular carcinoma (HCC) is a rising public health concern with few curative options but liver transplantion (LT) in highly selected cases. LT could save many other HCC patients but organ shortage has lead to the necessity of selection of patients with the best survival chances, namely the Milan criteria. Hepatocellular carcinoma (HCC) is the fifth most common cancer, and the third cause of cancer related-death worldwide. HCC incidence is rising in Western countries including Belgium. There are more than 1,000 new HCC diagnoses in Belgium every year, but only 90 to 100 patients suffering from HCC are listed for liver transplantation (LT). In fact, the scarcity of organ donors has forced the development of strict criteria to limit LT to patients who are likely to have excellent outcomes. The universally accepted LT criteria for HCC are the Milan criteria (1 HCC nodule ≤5 cm or 3 nodules ≤3cm) that lead to a low rate of post-LT recurrence (>80% of disease free recurrence at 5 years). The majority of patients suffering from HCC outside the Milan criteria at the time of diagnosis is not eligible for LT and is therefore limited to palliative care. It is however considered that some of these patients with HCC outside the Milan criteria may benefit from LT with an acceptable risk of recurrence and chances of long-term disease-free survival (DFS). This fact has led to the extension of LT criteria for HCC in some centres in different countries, as for example the University of California San Francisco (UCSF) criteria, the up-to-seven criteria or the Asan criteria. The Belgian Liver-Intestine Allocation Committee (Be-LIAC) is a section of the Belgian Transplantation Society (BTS) composed of the 6 LT Belgian centres in charge of coordinating deceased LT activity in Belgium with the help of Eurotransplant. Be-LIAC has already built a retrospective HCC database that was successfully used for several scientific studies allowing international presentations and publications. Based on this successful experience, Be-LIAC is keen to continue with this national collaboration to initiate a prospective clinical observational database to better study the results of LT in Belgium and to evaluate potential of extension of LT criteria in HCC patients. Inclusion in this database will not change patient management or the allocation process of the liver grafts in Belgium. This project is financed by a 4-year (2019-2022) grant of the Belgian "Fondation contre le cancer" / "Stichting tegen Kanker".

This study is a genetic analysis of aberrations in circulating tumor DNA (ctDNA) in patients in Asian countries. This study protocol is divided into parts describing several subanalyses that differ in terms of cancer types, analytical methods, participating countries, and participating institutions.

With 8,000 related deaths per year, HCC is one of the most dangerous cancers in France. The main reason for the poor prognosis of HCC is most often a diagnosis at an advanced stage ineligible for curative treatment. In the field of oncology, low participation to screening is closely linked to socioeconomic status (e.g. level of education, income, employment). In HCC, the socioeconomic status is linked to incidence, overall survival and treatment allocation in US, UK and Australia. This suggests that the social environment should be taken into account when designing interventions and policies that allows facilitating the medical pathways for patients with HCC with the ultimate goal of improving the overall prognosis. However, the studies assessing the impact of social determinants on the management of HCC in France are limited. Bryère at al. reported that the highest incidence and the worst prognosis of HCC were observed in the most disadvantaged populations in France. To date, there is no available data concerning the influence of social determinants on: implementation of surveillance programs of HCC, stage of disease at the time of diagnosis or treatment allocation. This data is essential for better understanding the geographic disparities observed in France and for developing the strategies to remedy them. CHIEF is a multicenter longitudinal observational study of patients with HCC (ClinicalTrials.gov Identifier: NCT04348838), that will collect the exhaustive data including patient and tumor characteristics, diagnostic circumstances and modalities, care pathway from diagnostic imaging to referral to expert center, treatment allocation and implementation, and 5-year follow up including recurrent assessment of quality of life. Social-CHIEF is an ancillary study to the CHIEF cohort (approved by CHIEF scientific committee). The population of this study will consist in a subset of patients from the CHIEF prospectively included or already recruited who accept to participate in this study. The data collected in CHIEF will be retrieved from the CHIEF main database and additional data about social determinants will be specifically investigated by self-administrated questionnaires. The results obtained will provide a better understanding of the influence of social determinants on health trajectories of HCC patients. These data will be essential in recommending new health policies and in designing innovative intervention studies to address social disparities.

Patients with gastric or colon cancer with peritoneal carcinomatosis will receive a biopsy of the tumor during their primary curative surgery. The operation is performed according to standard and includes resection of the primary tumor and any metastases and followed by HIPEC (Intraperitoneal hyperthermic chemoperfusion) according to the respective hospital standard. Organoid cultures from the biopsies are established in the research laboratory. Various chemotherapeutic agents are tested on these tumor organoids in the laboratory and the tumor organoids are analyzed in detail with regard to genetic alterations in order to find alterations that can be addressed, if necessary, by means of targeted drugs against peritoneal carcinomatosis.

Thyroid carcinoma is the common endocrine system malignant neoplasm. At present it has become the malignant neoplasm of fastest growing incidence rate. More than 85% thyroid carcinoma is papillary thyroid carcinoma. Cervical lymph node metastasis is common in papillary thyroid carcinoma patients. This study aim to reveal protein expression differences between papillary thyroid carcinoma with cervical lymph node metastasis and without cervical lymph node metastasis.

Implementation of a curative strategy of treatment in peritoneal carcinomatosis of gastric cancer. The goal is to get 1C level of evidence (patient died with "standard" treatment, with this treatment some of them survive) in terms of disease free survival and overall survival. Methodology: prospective, phase II, multicentric in Spain. Recruitment of 50 patients(to have 31 on treatment) in three years. This strategy is based on neoadjuvant systemic plus simultaneous intraperitoneal and intravenous chemotherapy(NIPS),to treat peritoneal disease by bi-directional approach; next step is cytoreductive surgery and HIPEC. Once patients are discharged, they will follow a systemic adjuvant chemotherapy protocol.

This 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.

This research trial studies kidney tumors in younger patients. Collecting and storing samples of tumor tissue, blood, and urine from patients with cancer to study in the laboratory may help doctors learn more about changes that occur in deoxyribonucleic acid (DNA) and identify biomarkers related to cancer.

This 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.
