R0 surgery is defined as microscopically margin-negative resection at the histopatological exam.; Overall Survival (OS) is defined as the time from enrolment to death from any cause. For patients still alive at the time of analysis, the OS time will be censored on the last date the patients were known to be alive.; Quality of Life, assessed using the EORTC QLQ-C30, the EORTC QLQ-CR29 and the EuroQol EQ-5D questionnaires, and Rectal Continence, assessed using LARS and St. Mark Continence scores, will be evaluate at specific time-points (baseline, after radiotherapy and chemotherapy, after surgery and during follow-up) and will be assessed through descriptive summary statistics. |

La determinazione della recidiva di malattia sarà basata sulle misure riportate dello sperimentatore. I pazienti che sono vivi senza avere nessuno degli eventi sopra citati al momento dell’analisi saranno censorizzati all’ultima valutazione radiologica.; Tasso di tossicità complessiva, definita come percentuale dei pazienti, relativi al totale dei pazienti che ricevono la radioterapia e almeno un ciclo di chemioterapia, in cui si verifica qualsiasi evento avverso in base ai criteri RTOGTC durante la radioterapia short-course e in base ai criteri NCICTC versione 5 durante la chemioterapia di consolidamento; Tasso di tossicità di grado 3-4, definita come percentuale dei pazienti, relativi al totale dei pazienti che ricevono la radioterapia e almeno un ciclo di chemioterapia, in cui si verifica un evento avverso di grado 3-4 in base ai criteri RTOGTC durante la radioterapia short-course e in base ai criteri NCICTC versione 5 durante la chemioterapia di consolidamento.; Tasso di resezioni R0, definito come la percentuale di pazienti, relativi al totale dei pazienti arruolati, sottoposti ad una resezione R0 del tumore primitivo. La chirurgia R0 è definita come resezione con margini di resezione microscopicamente negativi all’esame istopatologico.; Sopravvivenza complessiva, definita come il tempo tra l’arruolamento e la morte per qualsiasi causa. Per i pazienti ancora vivi al momento dell’analisi, l’OS sarà censorizzata all’ultima data in cui il paziente è noto essere vivo.; Qualità della vita (QoL), valutata usando i questionari dell’EORTC QLQ-C30, EORTC QLQ-CR29 e EuroQol EQ-5D, e la Continenza rettale, valutata usando gli score LARS e St. Mark’s Continence, saranno valutati in specifici momenti (basale, dopo radioterapia e chemioterapia, dopo chirurgia e durante il follow-up) e analizzati con una statistica sommaria descrittiva. |
