Over the past few decades, oncological research and radiotherapy techniques have experienced massive improvements. However, many treatments that are currently used suffer from mild to severe side-effects. Focusing on the case of radiotherapy for prostate cancer patients, we assess the already suggested possibility of predicting long-term radiotoxicity through genomic factors. We construct and validate a radiosensitivity indicator that is based on the analysis of SNPs (Single Nucleotide Polimorphism) sequences. Differently from previous works, we directly account for interactions among SNPs and provide a final score that can be easily incorporated into larger models that allow for additional predictors.
Negli ultimi decenni, la ricerca oncologica e le tecniche di radioterapia hanno visto miglioramenti sostanziali. Tuttavia, molti dei trattamenti utilizzati soffrono al momento di effetti collaterali blandi e severi. Concentrandoci sul caso della radioterapia per pazienti con cancro alla prostata, indaghiamo la possibilità, già suggerita da ricerche precedenti, di predire la radiotossicità tardiva attraverso fattori genetici. Quindi, costruiamo e validiamo un indicatore di radiosensibilità basato sull’analisi di sequenze di SNPs (Single Nucleotide Polimorphism). Diversamente da altri lavori in letteratura, teniamo esplicitamente conto di possibili interazioni tra SNPs e forniamo uno score finale facilmente incorporabile in modelli con predittori aggiuntivi.

Abstract
Over the past few decades, oncological research and radiotherapy techniques have experienced massive improvements. However, many treatments that are currently used suffer from mild to severe side-effects. Focusing on the case of radiotherapy for prostate cancer patients, we assess the already suggested possibility of predicting long-term radiotoxicity through genomic factors. We construct and validate a radiosensitivity indicator that is based on the analysis of SNPs (Single Nucleotide Polimorphism) sequences. Differently from previous works, we directly account for interactions among SNPs and provide a final score that can be easily incorporated into larger models that allow for additional predictors.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
