title: Research trends in the treatment of colorectal cancer.
abstract: Colorectal carcinoma ranks second in incidence after lung cancer in males and breast carcinoma in females. Within the clinical research on this tumor, new molecules of antineoplastic agents and new combined modality treatments have been introduced. From the examination of ongoing protocols some trends can be identified: the interest in immunotherapy and genetic therapy, frequently tested in combination with chemotherapy; the effort at the optimization of the administration of antineoplastic agents in the most common sites of metastatic lesions by hepatic or intraperitoneal infusion; the trend to a more aggressive treatment of metastastatic lesions with hyperthermia and cryoablation as well with the combination of systemic therapy and surgery. As far as radiotherapy is concerned, the main goals of clinical research seem represented by the need to optimize combined modality therapy in T3-4 rectal carcinoma both in terms of pre- and postoperative radiotherapy timing as well as of the combination with adjuvant chemotherapy. There is a growing interest in new drugs which in the future may replace the conventional 5-fluorouracil in concurrent chemoradiation.
