Active clinical trials for "Carcinoma, Neuroendocrine"

Background: Neuroendocrine neoplasm (NENs)are rare cancers arising from the neuroendocrine cells and can affect almost any part of the body. They vary from low grade neuroendocrine tumors (NETs) to high grade neuroendocrine carcinomas (NECs). These tumors often occur in the gastrointestinal tract, pancreas, lungs, adrenal medulla (pheochromocytomas) or adrenal cortex (adrenocortical cancer) and other areas of the body mentioned below: Gastroenteropancreatic neuroendocrine tumors (GEP-NET): stomach, duodenum, pancreas, colon, appendix, etc. Liver and gallbladder Adrenal tumors Pituitary gland Thyroid gland: medullary thyroid carcinoma Parathyroid tumors Pulmonary neuroendocrine tumors: typical and atypical carcinoid, small cell lung cancer (SCLC), large cell neuroendocrine carcinoma (LCNEC) Extrapulmonary small cell cancer Peripheral nervous system tumors: paraganglioma, neuroblastoma) Breast and genitourinary tract Their rates are rising in the United States and worldwide. Researchers want to learn more about NENs through this natural history study. Objective: To study the natural history of people with NENs and obtain samples from them to learn more about the disease. The clinical management of all NETs is not standardized, with only a few FDA-approved therapies and we would like to learn which combination therapeutic approach should be used, how long treatment should be continued, and in what subgroup of NENs a particular treatment option should be used. Eligibility: People aged 18 and older who have or are suspected to have NENs or ACC. Design: Participants will be screened with a medical history. Participants will have a physical exam. Their symptoms and their ability to perform their normal activities will be reviewed. They will have blood and urine tests. Participants will receive recommendations for managing their disease and potential treatment options. They will be able to ask as many questions as they would like. Participants may provide saliva, blood, and stool samples for research. They will give tumor samples from a previous surgery or biopsy. Participants may have optional biopsies. During biopsies, cancer tissue will be obtained using a needle and syringe. Tissue will be taken from the liver, lung, or a lymph node. Participants may have an imaging scan or ultrasound to help locate the tumor or area to be biopsied. They will receive local anesthesia and may be sedated. Participants will complete a questionnaire about their family medical history. Participants will have follow-up visits every 6 months. They will have physical exams and give samples. If their health changes, they may have extra visits. If they cannot visit NIH, they (or their doctor) will be contacted by phone or email. Participants will take part in the study for all their life.

This study collects information and data on patients with neuroendocrine cervical cancer. Information from this study may be used to better understand the correlation between clinical data, such as patient characteristics, treatment, and disease outcomes, and overall patient outcomes.

The purpose of this study is evaluate the efficacy and safety of FOLFIRINOX in patients with gastroenteropancreatic high-grade neuroendocrine carcinomas. This is a prospective Phase II open-label trial, stratifying gastroenteropancreatic high grade neuroendocrine carcinomas participants equally into two cohorts (first-line versus beyond first-line).

Background: - Neuroendocrine tumors (NETs) come from cells of the hormonal and nervous systems. Some people have surgery to shrink the tumor. Sometimes the tumors come back. Researchers think that treatment with drugs based on knowing the defective gene might give better results. Objective: - To see if drugs selected based on the defective gene result in better tumor response. The drugs are Sunitinib and Everolimus. Eligibility: - People age 18 and older with an advanced low- or intermediate-grade gastrointestinal or pancreatic neuroendocrine tumor. Design: Participants will be screened with: Medical history Physical exam Scans Blood, urine, and lab tests The study team will see if participants should have surgery. If yes, participants will: Sign a separate consent Have computed tomography (CT) scan before and after surgery Have as much of the tumor removed as possible. A small piece will be tested for mutation type. If no, participants will have a small piece of tumor removed for the testing. If the surgery might cure them, the participant will leave the study. The other participants will be assigned to take either Sunitinib or Everolimus. Participants will take their drug by mouth once a day. They will keep a medicine diary. Some will keep track of their blood pressure at least weekly. Screening tests may be repeated at study visits. Participants also may have their heart evaluated. About 30 days after the last day of their study drug, participants will have a follow-up visit that repeats the screening tests. Participants will be contacted every 3 months after this visit.

The primary purpose of the study is to investigate the effects of high-dose octreotide on flushing, diarrhea, and quality of life in patients whose disease-related symptoms are inadequately controlled by the maximum approved dose of octreotide LAR.

To assess the diagnostic accuracy of 18F-Fluorocholine PET/CT for the detection of medullary thyroid cancer in patients with primary and recurrent disease.

RATIONALE: Radiation therapy uses high-energy x-rays and other sources to damage tumor cells. Giving radiation therapy in different ways may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of indium In 111 pentetreotide in treating patients who have refractory cancer.

This is an open label, non-randomized phase 2 study to assess overall response rate (ORR), clinical benefit rate (CBR), overall survival (OS) and progression free survival (PFS) in patients with high grade neuroendocrine tumors treated with pembrolizumab 200mg Q 3 Weeks.

This phase II trial studies how well antiandrogen therapy, abiraterone acetate, and prednisone with or without neutron radiation therapy work in treating patients with prostate cancer. Hormone therapy such as antiandrogen therapy may fight prostate cancer by blocking the production and interfering with the action of hormones. Abiraterone acetate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as prednisone, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Neutron radiation therapy uses high energy neutrons to kill tumor cells and shrink tumors. It is not yet known whether antiandrogen therapy, abiraterone acetate, and prednisone with or without neutron radiation therapy may work better in treating patients with prostate cancer.

The study will be conducted to compare the safety and efficacy of irinotecan combined with cisplatin (IP regimen) and etoposide combined with cisplatin (EP regimen) in advanced or metastatic gastrointestinal pancreatic and esophageal neuroendocrine carcinoma. In this prospective randomized phase II study, the investigators aim to compare the survival benefit as well as the safety for irinotecan combined with cisplatin (IP regimen) versus etoposide combined with cisplatin (EP regimen) in advanced or metastatic gastrointestinal pancreatic and esophageal neuroendocrine carcinoma.
