Hepatic Artery Infusion of Carfilzomib in Participants With Liver Metastatic Disease Previously Treated With Hepatic Artery Infusion Pump Therapy

Background: Cancers that begin in the colon, adrenal glands, or bile ducts may spread to the liver. These liver tumors are often treated using a hepatic artery infusion (HAI) pump. The HAI pump is installed in the artery that goes to the liver; drugs are administered directly to the liver through this pump. But these tumors often return after treatment. Carfilzomib (CFZ) is a drug approved to treat another kind of cancer. Researchers want to find out if this drug may be helpful when administered through the HAI pump directly to the liver for people with colon, adrenal glands, or bile duct cancer that has spread to the liver. Objective: To test the safety of carfilzomib (CFZ) delivered via a hepatic artery infusion (HAI) pump directly to the liver in people with cancer in their liver. Eligibility: People aged 18 years or older with cancers of the colon, adrenal glands, or bile ducts that spread to the liver and persist after treatment. They must have a functioning hepatic artery infusion (HAI) pump in place from previous treatment of HAI pump therapy. Design: Participants will be screened. They will have a physical exam, blood tests, imaging scans, and a test of their heart function. They will also have a test to show how the blood flows through their liver: A radioactive substance will be injected into a vein, and a special camera will take pictures of the blood flow for up to 1 hour. Participants will receive the study drug for about 6 months. They will visit the clinic once a week. Their HAI pump will be filled with the drug at each visit; the drug will slowly drain from the pump into the liver. Blood tests and imaging scans will be repeated during the study. Participants will have follow-up visits 1 and 3 months after their last dose of study drug. An optional liver biopsy (tissue sample) for research purposes may be done before the study drug is given, and again (optional) within 28 days after first receiving the study drug. Individuals may participate in the study even if they do not agree to have the biopsies done. ...

Metarrestin (ML-246) in Subjects With Metastatic Solid Tumors

Background: Metastasis is the spread of cancer from one organ to a nonadjacent organ. It causes 90% of cancer deaths. No treatment specifically prevents or reduces metastasis. Researchers hope a new drug can help. It stops cancer cells from growing and spreading further and possibly shrink cancer lesions in distant organs. Objective: To find a safe dose of metarrestin and to see if this dose shrinks tumors. Eligibility: Adults age 18 and older with pancreatic cancer, breast cancer, or a solid tumor that has not been cured by standard therapies. Also, children age 12-17 with a solid tumor (other than a muscle tumor) with no standard therapy options. Design: Participants will be screened with: * blood tests * physical exam * documentation of disease confirmation or tumor biopsy * electrocardiogram to evaluate the heart * review of their medicines and their ability to do their normal activities Participants will take metarrestin by mouth until they cannot tolerate it or stop to benefit from it. They will keep a medicine diary. Participants will visit the Clinical Center. During the first month there are two brief hospital stays required with visits weekly or every other week thereafter. They will repeat some of the screening tests. They will fill out questionnaires. They will have tests of their cognitive function. They will have an electroencephalogram to record brain activity. They will have a computed tomography (CT) scan or magnetic resonance imaging (MRI). A CT is a series of X-rays of the body. An MRI uses magnets and radio waves to take pictures of the body. Adult participants may have tumor biopsies. Participants will have a follow-up visit 30 days after treatment ends. Then they will have follow-up phone calls or emails every 6 months for the rest of their life or until the study ends.

SND002 Cell Injection in Participants With Advanced Malignant Solid Tumors

This is a phase 1, multicenter, open-label, single-arm study evaluating SND002 Cell Injection in participants with advanced malignant solid tumors that have progressed after standard treatment or for whom no standard treatment is available. SND002 Cell Injection is an investigational product made from a participant's own immune cells (T cells). These cells are collected from a lymph node that drains the tumor, expanded in a laboratory, and then given back to the same participant by intravenous infusion. Because the cells come from the participant, the approach is intended to help the participant's immune system recognize and attack the tumor. The study has two parts. In Part A, small groups of participants receive increasing numbers of cells to identify the dose range that is safest and best tolerated. In Part B, additional participants with colorectal cancer, gastric cancer, or other solid tumors receive the dose range selected in Part A, to learn more about antitumor activity. Before the infusion, participants receive a short course of chemotherapy to prepare the body for the cells. After the infusion, participants receive interleukin-2 injections for several days and are monitored closely. Safety is assessed for 28 days after the infusion, and participants are then followed for up to 1 year to assess tumor response and survival. The main questions are (1) what side effects occur, how severe they are, and what dose range is recommended for further study, and (2) in the expansion part, how many participants experience a reduction in tumor size. Approximately 69 to 78 participants will be enrolled at multiple hospitals in China. Follow-up continues for up to 1 year after the infusion.

Obtaining Solid Tumor Tissue From People Having Biopsy or Surgery for Certain Types of Cancer

Background: \- Recent advances in cancer research have led to new therapies to treat the disease. It is important to continue these advances and discover new ones. To do that, researchers need tissue samples from solid tumors. This study will collect such samples from people already scheduled to have a procedure at the National Institutes of Health Clinical Center (NIHCC). Objectives: \- To collect tissue samples for use in studying new ways to treat tumors. Eligibility: * Adults 18 years and older, with a precancerous or cancerous solid tumor who are scheduled to have surgery or a biopsy at the NIHCC. * Children under the age of 18 but who are older than 2 years of age are eligible to be enrolled on the research sample collection portion of this study if they will have a biopsy or surgery as part of their medical care. Design: * Before their procedure, participants will have a small blood sample taken. * Some participants will undergo leukapheresis. In this procedure, blood is removed through a tube in one arm and circulated through a machine that removes white blood cells. The blood, minus the white blood cells, is returned through a tube in the other arm. The procedure takes 3-4 hours. * For all participants, during the surgery or biopsy, pieces of the tumor and pieces of normal tissue near it will be removed for this study. The rest of the tumor or precancerous growth will be sent to a lab for analysis. * Participants will return to the clinic about 6 weeks after the operation for a routine checkup. Some may have to return for additional follow-up.

Resistance vs Aerobic Prehabilitation Before Colorectal Cancer Surgery

The goal of this clinical trial is to learn which type of exercise before surgery best reduces complications after colorectal surgery in adults with colorectal cancer or precancerous lesions. The main questions it aims to answer are: * Does resistance (strength) training, aerobic (endurance) training, or a combination of both before surgery lower the rate and severity of complications in the first 30 days after surgery, compared with no exercise program? * Which factors influence how well patients follow a prehabilitation program, and does following the program affect surgical outcomes? Researchers will compare three exercise groups with a control group that receives standard care without an exercise program. Participants will: * Be randomly assigned to one of four groups: resistance training, aerobic training, combined training, or no exercise program (control) * Do the assigned home exercise program for 4 to 6 weeks before surgery, with weekly physiotherapy check-ups in person or by phone * Receive nutritional counseling, breathing exercises, and psychological support if needed, regardless of group * Keep a daily exercise diary and record their pulse daily * Undergo physical fitness tests (walking test, sit-to-stand test, handgrip strength) and quality-of-life questionnaires before surgery and 8 weeks after surgery

Follow-up After Oncological Resection by Endoscopic Colorectal ESD (Endoscopic Submucosal Dissection)

Colorectal cancer is a common and leading cause of death. Pre-cancerous lesions, as well as some so-called superficial cancers, can be resected via endoscopy. The technique chosen in the case of extensive lesions or superficial cancer is submucosal dissection. This technique helps avoid surgery, which has a higher morbidity and mortality (especially due to the non-preservation of the organ).

PDS01ADC in Combination With Hepatic Artery Infusion Pump (HAIP) and Systemic Therapy for Subjects With Metastatic Colorectal Cancer, Intrahepatic Cholangiocarcinoma, or Metastatic Adrenocortical Carcinoma

Background: One way to treat liver cancer is to deliver chemotherapy drugs only to the liver (and not to the whole body). Researchers want to see if adding the drug PDS01ADC can improve the treatment. The drug triggers the immune system to fight cancer.\<TAB\> Objective: To see if treatment with HAIPs to deliver liver-directed FUDR and Dexamethasone chemotherapy in combination with PDS01ADC is effective for certain cancers. Eligibility: People aged 18 and older who have cancer of the bile ducts that is only in the liver, or colorectal cancer that has spread to the liver, or cancer of the adrenal glands that has spread to the liver, who are also receiving or planning to receive standard systemic chemotherapy for their disease. Design: Participants will be screened with: Medical history Physical exam Blood tests Pregnancy test (if needed) Tumor biopsy (if needed) Electrocardiogram Computed tomography (CT) scans Participants will have an abdominal operation. A catheter will be placed into an artery that feeds blood to the liver. The catheter will then be attached to the HAIP. The HAIP will lay under the skin on the left side of the abdomen. All participants will have liver-directed FUDR and Dexamethasone chemotherapy drugs or heparin with saline infused into the HAIP every 2 weeks. PDS01ADC will be injected under the skin every 4 weeks. They will receive this treatment until their cancer gets worse or they have bad side effects. Participants will also receive standard systemic chemotherapy for their disease, assigned based on diagnosis, through an IV by their medical oncologist (at NIH or by a local provider) every 2 weeks. Participants will have 2 study visits at NIH each month. They will have CT scans every 8 weeks. At visits, they will repeat some screening tests. Participants will have a follow-up visit 1 month after treatment ends. Then they will be contacted every 6 months for 5 years.

A Study to Learn About the Study Medicine PF-07934040 When Given Alone or With Other Anti-cancer Therapies in People With Advanced Solid Tumors That Have a Genetic Mutation.

The purpose of this study is to learn about the safety and effects of the study medicine alone or when given together with other anti-cancer therapies. This study also aims to find the best dose. This study is seeking participants who have solid tumors (a mass of abnormal cells that forms a lump or growth in the body) that: * are advanced (cancer that doesn't disappear or stay away with treatment) and * have a KRAS gene mutation (a change in the DNA of the KRAS gene that can cause cells to grow in very high numbers). This includes (but limited to) the following cancer types: Non-Small Cell Lung Cancer (NSCLC): It's a type of lung cancer where the cells grow slowly but often spread to other parts of the body. Colorectal Cancer (CRC): This is a disease where cells in the colon (a part of large intestine) or rectum grow out of control. Pancreatic ductal adenocarcinoma (PDAC): This is a cancer that starts in the ducts of the pancreas but can spread quickly to other parts of the body. Pancreas is a long, flat gland that lies in the abdomen behind the stomach. Pancreas creates enzymes that help with digestion. It also makes hormones that can help control your blood sugar levels. All participants in this study will take the study medication (PF-07934040) as pill by mouth twice a day repeating for 21-day or 28-day cycles. Depending on which part of the study participants are enrolled into they will receive the study medication (PF-07934040 alone or in combination with other anti-cancer medications). These anti-cancer medications will be given in the study clinic by intravenous (IV) that is directly injected into the veins at various times (depending on the treatment) during the 21-day or 28-day cycle. Participants can continue to take the study medication (PF-07934040) and the combination anti-cancer therapy until their cancer is no longer responding. The study will look at the experiences of people receiving the study medicines. This will help see if the study medicines are safe and effective. Participants will be involved in this study for up to 4 years. During this time, they will come into the clinic between 1 to 4 times in each 21-day or 28-day cycle. After they have stopped taking the study medication (at about at 2 years) they will be followed for another two years to see how they are doing.
