Reviving the Autopsy for Modern Cancer Evolution Research.

Area of Science:

• Oncology
• Cancer Biology
• Pathology

Background:

• Tumor evolution and heterogeneity present significant challenges in oncology, including treatment resistance and immune evasion.
• Limited tissue samples from clinical care hinder comprehensive study of these complex cancer biology questions.
• Autopsy studies offer a unique opportunity to investigate tumor evolution using a broader range of cancer tissues.

Purpose of the Study:

• To review the progress made in understanding cancer evolution through autopsy studies.
• To highlight the value of autopsy-derived tissue resources for future cancer research.
• To emphasize the role of research autopsies in advancing cancer care.

Main Methods:

• Review of existing literature and data from completed autopsy studies.
• Analysis of insights gained regarding metastatic cell origins and genomic events.
• Examination of tissue resources generated from autopsies, such as patient-derived xenografts and cell lines.

Main Results:

• Autopsy studies have elucidated the shared origin of metastatic cells.
• Early whole-genome doubling events are critical for amplifying survival genes in tumors.
• Autopsies have generated valuable resources like banked tissues, cell lines, and patient-derived xenografts.

Conclusions:

• Cancer tissues collected at autopsy have significantly advanced our understanding of tumor evolution.
• Autopsy programs provide essential resources for addressing future questions in cancer research.
• Research autopsies represent a vital contribution from patients to improve cancer care.
