This trial studies health outcomes after treatment in patients with retinoblastoma. Gathering health information over time from patients and family members through vision assessments, samples of tissue and saliva, and questionnaires may help doctors learn more about what causes retinoblastoma, identify long-term health outcomes for patients with retinoblastoma, and find out which therapies may be the best for treating retinoblastoma.

This study compares therapy within the bladder (intravesical therapy) and surgery as treatment options for patients with bladder cancer. Bladder cancer is the fifth most common cancer in the United States, but not enough research is available to help patients decide between the two most common treatments: medical therapies or bladder removal. The purpose of this study is to compare how the two treatments affect patient clinical outcomes and patient and caregiver experiences. This study may help researchers improve the decision-making process about bladder cancer treatments for patients and their caregivers.

This trial tests the use of a disposable perfusion phantom (P4) to decrease errors in calculating the blood flow of a tissue with DCE-MRI. DCE-MRI is used calculate blood flow of various tissues including tumors. Blood flow often serves as a critical indicator showing a disease status. For example, a pancreatic tumor has typically low blood flow, so it can be used as an indicator to identify the presence of a pancreatic tumor. In addition, an effective therapy may result in the increase of blood flow in a pancreatic tumor during the early period of treatment. Therefore, DCE-MRI may be used to determine whether the undergoing therapy is effective or not by measuring the change of blood flow in the pancreatic tumor and may help doctors decide whether to continue the therapy or try a different one. Unfortunately, the measurement of blood flow using DCE-MRI is not accurate. The use of an artificial tissue, named "phantom" or P4, together with a patient may help to reduce errors in DCE-MRI because errors will affect the images of both the patient and the phantom. Because it is known how the blood flow of the phantom appears when no errors are present, the phantom may be used to detect what kinds of errors are present in the image, how many errors are present in the image, and how to remove errors from the image.

To compare the effectiveness of an APCD to Usual Care in the management of lymphedema and
fibrosis (LEF) in head and neck cancer (HNC) survivors.

This phase II trial tests whether designing radiation to avoid bone marrow in the spine (vertebral bone marrow) leads to less reduction of white blood cell counts (lymphopenia) in patients with lung cancer. This sparing technique could lead to better disease control and outcome.

This study gathers health information for the Project: Every Child for younger patients with cancer. Gathering health information over time from younger patients with cancer may help doctors find better methods of treatment and on-going care.

This study is an access and distribution protocol for unlicensed cryopreserved cord blood
units (CBUs) in pediatric and adult patients with hematologic malignancies and other
indications.

The primary purpose of the Research Database is to have a comprehensive source of
observational data that can be used to study HSC transplantation and cellular therapies.

A secondary purpose of the Research Database is to have a comprehensive source of data to
study marrow toxic injuries.

Objectives:

To learn more about what makes stem cell transplants and cellular therapies work well such
as:

- Determine how well recipients recover from their transplants or cellular therapy;

- Determine how recovery after a transplant or cellular therapy can be improved;

- Determine how a donor's or recipient's genetics impact recipient recovery after a
transplant or cellular therapy;

- Determine how access to transplant or cellular therapy for different groups of patients
can be improved;

- Determine how well donors recover from the collection procedures.

This pilot trial compares drug exposure levels using a new method for dosing vincristine in infants and young children compared to the standard dosing method based on body surface area (BSA) in older children. Vincristine is an anticancer drug used to a variety of childhood cancers. The doses anticancer drugs in children must be adjusted based on the size of the child because children vary significantly in size (height, weight, and BSA) and ability to metabolize drugs from infancy to adolescence. The dose of most anticancer drugs is adjusted to BSA, which is calculated from a patients weight and height. However, infants and young children have more severe side effects if the BSA is used to calculate their dose, so new dosing models have to be made to safely give anticancer drugs to the youngest patients. This new method uses a BSA-banded approach to determine the dose. Collecting blood samples before and after a dose of the drug will help researchers determine whether this new vincristine dosing method results in equivalent drug levels in the blood over time in infants and young children compared to older children.

This study evaluates the patient reported outcomes in patients with digestive system neuroendocrine cancer and lung neuroendocrine cancer. Patients with neuroendocrine cancer usually have a high symptom burden which may have a negative effect on health-related quality of life (HRQoL). Patient questionnaires gather information describing symptoms and effect on quality of life, cancer type and any treatments received. Studying quality of life in patients receiving treatment for neuroendocrine cancers may help identify the effects of treatment and improve future treatment plans. Information gathered from this study may help researchers understand whether patient's diagnosis, symptoms, and order of cancer treatments have any effect on quality of life.
