ABSTRACT Questa tesi di dottorato è stata elaborata nella prospettiva di studiare l’applicazione della spettroscopia di risonanza magnetica protonica (1H MRS) nella possibile diagnosi istologica non invasiva dei polipi e del carcinoma colorettale. In particolare, la sua utilizzazione nella stadiazione del cancro del retto dopo trattamento neoadiuvante (chemioradioterapia concomitanti), che risulta fortemente deficitaria con le metodiche tradizionali (EUS, MRI, TC e PET- TC), potrebbe consentire diagnosi più accurate soprattutto di risposte cliniche complete o di residuo minimo di malattia. A tale scopo sono stati dapprima ricordati nella letteratura i risultati dell’uso delle metodiche di imaging tradizionali che non consentono scelte terapeutiche adeguate alla presenza della neoplasia, scelte che variano dalla astensione chirurgica ad interventi allargati e mutilanti. E’ stata rivista la utilizzazione su tumori umani (in vivo, ex-vivo e in studi sperimentali) della MRS, in modo specifico e più dettagliato, sul carcinoma colorettale. Infine nell’ultima parte della tesi sono stati riportati scopi, metodi, apparati tecnologici e risultati della ricerca attuata, costituita dall’uso della 1H MRS su pezzi operatori umani. Parole chiave: spettroscopia di risonanza magnetica, carcinoma colorettale
This PhD thesis has been prepared with a view to the study of the application of proton magnetic resonance spectroscopy (1H MRS) in the possible non-invasive histological diagnosis of colorectal polyps and cancer. In particular, its use in staging of rectal cancer after neoadjuvant treatment (concurrent chemoradiotherapy), which is heavily deficient with traditional methods (EUS, MRI, CT and PET-CT), could allow more accurate diagnosis, overall of clinical complete responses or minimal residual disease. choices ranging from abstention widened and mutilating surgical interventions.For this purpose, the results of the use of traditional imaging methods have been first of all remembered in the literature, results which do not allow appropriate therapeutic choices for cancer, ranging from surgical abstention to extended operations. The use of the MRS on human tumors (in vivo, ex vivo and in experimental studies) was reviewed, in a more specific and detailed matter, on colorectal carcinoma. Finally in the last part of the thesis aims, methods, technological equipments and results of implemented research, made of use of 1H MRS on human surgical specimens, have been reported.
