Condition: Rectal Neoplasm · Sponsor: Fondazione Policlinico Universitario Agostino Gemelli IRCCS
The introduction of neoadjuvant chemoradiation therapy (CRT) and the use of advanced surgical techniques have led to a reduction in mortality and recurrence rates for rectal cancer, the rate of which currently stands at 4-8%. Complete cytoreduction (achieving R0) of local recurrence is the main factor correlating with survival, but surgery can often be very complex because of the change in anatomical planes caused by previous surgery. Reirradiation of the recurrence may increase the rate of optimal resection (R0) and may palliate symptoms in unresectable disease. It is a very complex procedure, because one has to take into account the dose previously received by the organs at risk (OARs) and at the same time be able to deliver an effective dose to the recurrence. However with modern irradiation techniques (VMAT) it is possible to increasingly spare the OARs and deliver adequate doses in this setting as well. Besides radiotherapy with conventional fractionation, other promising options are stereotactic body radiotherapy (SBRT) with and proton (PT) and carbon ion RT (CIRT). Another topic of interest is chemotherapy intensification (CHT): recent studies of concomitant and neoadjuvant chemotherapy (Total Neoadjuvant Therapy) have shown high rates of antitumour response, however even this option should be evaluated with caution, because it must take into account previous cancer treatments received by the patient. Based on the evidence reported in the literature, it is reasonable…
