Bevacizumab plus irinotecan, fluorouracil, and leucovorin for metastatic colorectal cancer. Abstract Colorectal cancer CRC is a common neoplasia in the Western countries, with considerable morbidity and mortality.
Treatment of advanced colorectal and gastric adenocarcinomas with 5-fluorouracil and high-dose folinic acid. Journal List World J Gastroenterol v.
Significantly, in their systematic review of papers comparing survival of patients undergoing the resection vs non-resection of the primary tumor, Verhoef et al[ 82 ] found that the resection of primary CRC was related to adkep prognosis in all papers including no or very few patients undergoing CHT[ 274779 ], whereas results were more ambiguous in series including patients undergoing CHT, where resective surgery resulted as being related to survival in some papers[ 5083 – 85 ] but not in others[ 485253617086 ].
Such a multimodal management of incurable CRC is responsible for a significant increase in survival of asjep affected by incurable CRC in general, which has passed from 8 to 14 mo over the last two decades[ 3 ], but has been reported to exceed two years in selected populations following the sequential use of various lines of treatment including the newest chemotherapeutic agents[ 1213 ].
Best supportive care; 5-FU: On the contrary, left-sided procedures are more time-consuming and associated to higher morbidity[ 75 ], including leakage and pelvic abscess[ 76 ].
Addition of aflibercept to fluorouracil, leucovorin, and irinotecan improves survival in a phase III randomized trial in patients with metastatic colorectal cancer previously treated with an oxaliplatin-based regimen. In fact, in asymptomatic patients, the management is aimed to slow down cancer progression, thus prolonging long-term survival and preventing cancer-related complications.
Algorithm for the management of severely symptomatic incurable stage IV colorectal cancer patients including emergency cases. The multimodal aekep to initially non-resectable liver axkep, including systemic CHT[ 121415 ], intraarterial CHT[ 1617 ], portal embolization[ 1819 ] and secondary surgery[ 2021 ], and its impact on survival[ 22 ], will be treated in a dedicated paragraph. Future development and open issues: Differently from ileal stomas, that present the main drawback of high volume, very irritating, liquid stools, colonic stomas have the advantage of lower-volume, solid stools, are normally easier to manage postoperatively and volon lower morbidity, thus representing the ideal solution for palliation[ 68 ].
Moreover, it should be considered that surgical coolon of the primary CRC may affect the following management by modifying CHT administration schedule: Early results of laparoscopic surgery for colorectal cancer.
Staging of peritoneal carcinomatosis: Differently, in emergency and severely symptomatic patients, it is focused in solving cancer-related complications, which may be rapidly fatal or imply intolerable symptoms.

YAG laser[ 55 ]. In asymptomatic patients, new chemotherapy regimens allow long survival and, potentially, conversion of non resectable liver metastasis in resectable ones, with a significantly improved prognosis.
Sincelaparoscopic surgery has been widely adopted in order to reduce the aggressiveness of surgery in incurable CRC patients[ 92 – 99 ]. The understanding of biological mechanisms at the basis of the disease and the discovery of molecular pathways leading to CRC progression have led to the development of new awkep drugs against CRC.
In recent times, the main role in the management of non-emergency patients affected by incurable CRC has passed from surgery to CHT. Outcomes of resection and non-resection strategies in management of patients with advanced colorectal cancer. Such a consideration may gain interest in the light of long-survival recently observed with last generation CHT. New agents, including pimasertib, have been evaluated by preclinical studies, showing promising results[ ].
Higher perioperative mortality and morbidity of CRC resection represent the counterpart of a supposed longer survival. Indeed, in pre-CHT era, the short life expectancy of advanced CRC led to consider stent positioning an effective, definitive palliation[ 48 ], allowing the prompt start of CHT.

Cx of the primary tumour versus no resection va to systemic therapy in patients with colon cancer and synchronous unresectable metastases UICC stage IV: Endoscopic transanal resection provides palliation equivalent to transabdominal resection in patients with metastatic rectal cancer. Incurable stenosing colorectal carcinoma: Last but not least, the positive psychological effect of not having a temporary or permanent colostomy is another positive effect of stent positioning[ ].
The oncosurgery approach to managing liver metastases from colorectal cancer: Transrectal ultrasound and magnetic resonance imaging measurement of extramural tumor spread in rectal cancer. The most commonly reported life-threatening complications of advanced CRC are obstruction and perforation[ 2751 ], but also bleeding and other minor symptoms will be discussed.
Laparoscopy may be as effective as laparotomy[ 65 ] with better early outcome and less long-term complications[ 6667 ]. Extended resections for CRC infiltrating contiguous organs, including anterior and posterior pelvic exenteration[ 7273 ], and hemicorporectomy[ 74 ] are not indicated in a palliative context anymore.
Therefore, it is difficult to make any generalization and any patient should be evaluated on a case by case basis. GKAs for diabetes therapy: Since APR implies a perineal wound which is associated to healing complications in roughly one half of the patients[ 77 ], sphincter-preserving techniques are generally preferred. Peritoneal colorectal carcinomatosis treated with surgery and perioperative intraperitoneal chemotherapy: Interestingly enough, although in some cases it is reported to reach Randomized, controlled trial of irinotecan plus infusional, bolus, or oral fluoropyrimidines in first-line treatment of metastatic colorectal cancer: Since the mids, self-expanding metallic stents have shown to be more effective than other treatments argon laser, plastic stent and have been proposed in the management of colorectal stenosis in order to avoid emergency surgery[ ].
