Unspecified Adult Solid Tumor, Protocol Specific

RATIONALE: Gathering information about older patients with cancer may help the study of cancer in the future. PURPOSE: This research study is gathering information from older patients with cancer into a registry.

RATIONALE: Collecting and storing samples of tissue or blood from patients with cancer for study in the laboratory may help the study of cancer in the future PURPOSE: This research study is collecting and storing blood and tissue samples from patients with suspected solid tumors.

This research trial studies using genomic profiling to recommend anticancer treatment to patients with cancer that has spread beyond the original site of the tumor (metastatic cancer). Genomic profiling studies the deoxyribonucleic acid (DNA) of a tumor to detect genetic changes or abnormalities. This information can then be used to recommend treatments that may be more likely to result in a beneficial response. It is not yet known whether genomic profiling will detect abnormalities that can be used to make treatment recommendations and whether treatment based on genomic profiling is more effective than standard treatment.

A modular, first time in human, open label, multiple dose, accelerated escalation with cohort expansion study of the safety and pharmacokinetics of intravenous infusion of CP-506, a tumor agnostic Hypoxia Activated Prodrug in patients with HRD/FAD solid tumours or tumor types with high incidence of HRD/FAD in monotherapy or in combination with carboplatin or patients with solid tumour and oligoprogressive disease receiving immune checkpoint inhibitors (ICI): a phase I-IIa clinical trial

RATIONALE: Diagnostic procedures, such as 3'-deoxy-3'-\[18F\] fluorothymidine (FLT) PET imaging, may help find and diagnose cancer. It may also help doctors predict a patient's response to treatment and help plan the best treatment. PURPOSE: This phase I trial is studying FLT PET imaging in patients with cancer.

RATIONALE: Collecting and storing samples of tissue from patients with cancer to test in the laboratory may help the study of cancer in the future. PURPOSE: This research study is collecting tissue samples from patients with cancer undergoing radiation therapy. Healthy participants will also be allowed on the trial so their samples can be used in comparison to patients with malignancy
