Unraveling the lexicon of complex mutational phenomena in human cancers.

Complex mutational phenomena in human cancers are characterized by distinct genomic patterns, with phenomena like chromothripsis and chromoplexy linked to specific molecular mechanisms.

• Why it matters: Understanding these phenomena is crucial because they influence tumor evolution, drug resistance, and clinical outcomes, yet their definitions and mechanisms remain ambiguous.
• What they did: The authors review and clarify the lexicon of mutational phenomena, including terms such as kataegis, omikli, and tyfonas, and explore their proposed origins and associations with mutational processes.
• The result: This comprehensive overview enables better interpretation of complex mutational patterns, aiding research into tumor development, resistance, and potential therapeutic strategies.
