RATIONALE: Follow-up of long-term cancer survivors who participated in a clinical trial may help health professionals better understand their disease and determine the long-term effects of treatment.

PURPOSE: This clinical trial is studying long-term cancer survivors to monitor their cancer and determine the effects of previous treatment.

OBJECTIVES:

• Provide follow-up visits for previously enrolled Center for Cancer Research patients who are long-term survivors and may not be currently entered on an active protocol.

OUTLINE: This is a follow-up study.

Patients undergo long-term standard tests and procedures, including laboratory tests, diagnostic radiography, and nuclear medicine studies based on the patient's diagnosis, prior therapy, and supporting clinical information, to follow course of disease and effects of prior therapies until the patient enters another active primary protocol OR follow-up is no longer required at the Center for Cancer Research.

PROJECTED ACCRUAL: A total of 1,000 patients will be accrued for this study.

PATIENT CHARACTERISTICS:

• Not specified

PRIOR CONCURRENT THERAPY:

• No concurrent investigational therapies or other treatments with therapeutic intent for the disease under observation
• No concurrent procedures that would entail more than minimal risk to the patient
