Filter by:Gastric, biliary and pancreatic cancer are commonly malignancies from gastro- intestinal tract in Taiwan. Because lack of specific symptoms at presentation and effective screening methodology, majority of these patients are diagnosed with metastatic or unresectable disease. Palliative chemotherapy is the good standard of therapy for patients with unresectable gastric, biliary and pancreatic cancer with benefit of prolong survival time and improve quality of life. Although the benefit of palliative chemotherapy seems to be the same for elderly and young cancer patients in clinical study, elderly patients are less frequently treated with chemotherapy or treated with suboptimal dosage. Elderly patients do not receive palliative chemotherapy because concerns of elder age, comorbidity, poor performance, lack of social/economic support and worry about treatment toxicities. The increase in life expectancy of the general population resulted in an increase in the number of elderly patients with cancers referred for palliative chemotherapy. Overtreatment may result in high mortality due to disregard of the aging patients' frailty; on the other hand, under-treatment resulting from over-concern regarding their ability to tolerate treatment, may compromise the survival outcome. Therefore, the appropriately selection of geriatric cancer patients for palliative chemotherapy has to be addressed urgently. Frailty is a progressive decline of physiological reserve leading to multiple functional disability and increases vulnerability to subsequent morbidity and mortality. Frailty is associated with treatment toxicity, chemotherapy tolerance, and survival outcome in clinical oncology. Recent randomized study reported geriatric intervention significantly improved chemotherapy tolerance in elderly patients. Therefore, the American Cancer Association has recommended routine geriatric assessment and intervention in oncogeriatric patients upon providing antitumor treatments. However, the effect of geriatric intervention on chemotherapy tolerance is seldom in Taiwan. This study is an open, randomized, prospective trial to evaluate the effect of geriatric intervention on chemotherapy tolerance in patients with unresectable gastric, biliary, and pancreatic cancer. All patients with receive frailty assessment within 7 days before initiation of first cycle palliative chemotherapy followed by geriatric intervention. The study aim is to compare for chemotherapy tolerance, treatment-related toxicity, and quality of life after completion 3 months chemotherapy treatment course between frail and non-frail patients. This study also aims to explore the effect of geriatric intervention of treatment tolerance, treatment-related toxicity, and quality of life in frail patients with gastric, biliary, and pancreatic cancer receiving palliative chemotherapy.
To determine the long term outcomes of Endoscopic Submucosal Dissection (ESD), Endoscopic Full Thickness Resection (EFTR) and Submucosal-Tunnelling Endoscopic Resection (STER) for upper gastrointestinal neoplastic lesions
This study aims to collect biospecimens and explore the correlation of genomics and prognosis in alimentary tract cancers.
This is an observational study with the goal to improve the robustness of the scientific evidence linking Fusobacterium nucleatum (Fn) and/or other microorganisms to colorectal cancer (CRC) onset and/or progression. This is an approximately three-year study. There are two phases to this study, including: 1) pilot phase, 2) full study. There are also five arms in this study including cancer-free, pre-cancerous, and Colorectal cancer stages (I-III). The pilot study will include the recruitment of 50 participants per group (i.e., total of 250 participants). The full study will have an additional 150 participants per group (total of 1,000 participants). This study will recruit using clinical sites in the United States. There are 5 timepoints in this study. If the participants are found to be medically eligible through diagnosis and medical information, they will provide samples (including: saliva, blood, urine, stool and tumor biopsy) at each timepoint and during the study. They will also answer health and wellness questions during this study. Additional data collection, including medical data, biopsies and other biological samples might happen at interim timepoints in case of adenoma/cancer disease progression (recurrence, metastasis). The participant's healthcare provider will determine if additional biopsies are required as a part of the standard of care. If collected, additional samples will be sent for research purposes.
The goal of this clinical research trial is to study the use of differing investigational doses and scheduling for Proton Therapy for tumors previously treated with radiation therapy. Generally, when patients are first treated for cancer with radiation therapy, they are treated with traditional photon (or x-ray) radiation therapy, which uses high-energy waves to kill tumor cells. In some cases, the cancer either returns or a new tumor can present in a different part of the body. With the usual radiation treatment, the photon beams travel all the way through the body. As a result, healthy tissues in front of and behind the tumor are exposed to radiation. Physicians who treat these cases where the tumor has returned often use a much lower dose of radiation to prevent patients from experiencing serious and long-term side-effects. This dose is often not strong enough to destroy the cancerous tumor. Alternatively, they may also treat a smaller area than would be indicated for complete tumor eradication, again in an attempt to prevent serious and long-term toxicities, but at the cost of optimally treating the cancer. Proton therapy, however, may offer a chance to safely deliver a more effective dose and volume of radiation as it is more targeted and can spare healthy tissues surrounding the tumor. The reason we are conducting this research study is to look at whether Proton therapy can be a better way to treat reoccurring tumors in patients who have previously received radiation therapy to the same area, compared to treatment approaches used to date.
The purpose of this study is to understand the breadth of molecular characteristics present in participants cared for in a large integrated, community-based health care system. Using comprehensive genomic profiling and proteomics, the investigators seek to identify the underlying genomic drivers of premalignant or malignant conditions in participants across different stages of disease development and cancer types. Comprehensive molecular profiling will consist of somatic tumor testing (tissue and/or blood) using whole exome sequencing, whole transcriptome sequencing, proteomics, and selected instances of whole genome sequencing. In addition, the investigators seek to perform broad hereditary cancer testing in affected participant populations. Hereditary testing has implications in screening, prognosis, and therapeutics for affected participants, as well as broad implications for genetic counseling and cascade testing. In order to maximize the value of genomic information, participants consented to this protocol will have their electronic health records (both retrospectively and prospectively) abstracted, curated, annotated and linked to genomic information obtained though the testing performed. Given the long-term value of this data, participants will also be asked to voluntarily consent to have their samples stored in a biobank and have their de-identified information used for future research. Information collected across this participant population will aid in advancing the investigators' knowledge of cancer biology, to discover and validate biomarkers associated with clinical outcomes, and shared in collaborative projects in order to promote the study of cancer.
This study is designed for participants who have cancer of the upper gastrointestinal (GI) tract such as cancer of the esophagus, stomach, duodenum (the initial portion of your small intestine), pancreas, bile duct (Cholangiocarcinoma), ampulla, or gall bladder with limited sites of spread (metastases). Doctors leading this study are looking to see if treating the disease using sequential procedures (more than one procedure given one after another) such as surgeries or radiation can lead to better survival and if these surgeries, combined with standard of care treatment, are safe for the treatment of upper GI cancers.
In order for the diagnosis of digestive system tumors and their appropriate treatment afterward, the type of these tumors should be determined by the pathologist. Pathology doctors need sufficient tissue (a small part of the organ thought to be diseased) to make a diagnosis. Tissue samples were taken from the patients by biopsy procedure. It is examined with microscopes by performing various staining and occasionally it is reported that sufficient tissue cannot be provided to make a diagnosis. In this case, patients may be subjected to repeated biopsy procedures. The aim of this study is to investigate whether the biopsy material obtained by endoscopic ultrasonography (EUS) is sufficient for the diagnosis of the pathology physician with the naked eye. Researchers will try to determine to what extent the physician performing the biopsy procedure can predict whether the tissue he has obtained is sufficient for the pathologist. In this way, researchers think that fewer biopsy repetitions will be needed in the future.
Our objective is to initiate an exercise program for patients with advanced GI or Gyn cancer, as prehabilitation prior to surgery. The objective of the prehabilitation program is to reduce complication rates and improve the length and quality of survival for patients with abdominal cancer. The prehabilitation program will be offered to patients who are eligible for and consent to cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC)
This study is to assess the usability and acceptability of a digital food consumption diary as part of the perioperative management of gastrointestinal oncology patients and to evaluate the impact of a digital food diary on adherence to dietician-recommended plan and on quality recovery, using a commercially available smart phone application.
