Late complications related to palliative stenting in patients with obstructing colorectal cancer. First, the success rate and morbidity of stenting seems to be different between the sigmoid-rectum and the remaining colon, where the intraperitoneal location and anatomic variability may be supposed to cause lower success rate and higher morbidity, cplon perforation[ ].

Initial presentation with stage IV colorectal cancer: Bevacizumab in combination with oxaliplatin-based chemotherapy as first-line therapy in metastatic colorectal cancer: Traditionally managed surgically, by resection of the primitive tumor, intestinal bypass or stoma[ 6 – 8 ], the palliative approach to incurable stage IV CRC patients has significantly changed over the last three decades and is nowadays multidisciplinary, with a pivotal role played by chemotherapy CHT [ 9 – 11 ].
This latter have allowed for a dramatic increase in survival, whereas the role of colonic and liver surgery is nowadays matter of debate. The vascularisation of the colonic remnant must be respected, and any manoeuvre aimed to avoid any tension at the anastomosis-site should be performed, including colonic dissection and inferior mesentery vein division, if needed. Endoscopic methods other than stents for palliation of rectal carcinoma.
The beneficial effect of palliative resection in metastatic colorectal cancer. 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.
Accordingly, international guidelines suggest nowadays to avoid surgery in the oclon of patients with incurable metastasis cllon CRC, unless in the presence of or in the imminent risk of complications such as obstruction or significant bleeding[ 33 ].
Staging of primary colorectal carcinomas with fluorine fluorodeoxyglucose whole-body PET: All non-resective procedures radiotherapy, laser therapy, APC and transanal procedures should not be considered as excluding each other, but as multiple options to be used whenever other managements have failed.

Algorithm for the management of incurable copon or minimally symptomatic stage IV colorectal cancer patients. Journal List World J Gastroenterol v. If we add that, owing to technical reasons, it may be difficult or impossible to stent low rectum cancers approaching to the anus, we can deduce that a not negligible part of CRCs are not suitable for stenting.
In general, it should be reminded that any complication, even minor, may significantly affect the short residual life. Randomized, controlled trial of coloj plus infusional, bolus, or oral fluoropyrimidines in first-line treatment of metastatic colorectal cancer: First appeared in scientific literature in the mid-twentieth century[ 4647 ], the management of incurable metastatic CRC still represent a matter of debate among oncologists, and surgeons.
Combined treatment coolon lasertherapy Nd: Importantly, if the non-resectability is due to distant metastasis, technical difficulty of resection is comparable to curative surgery, whereas, if the reason of non resectability is the cx, surgery may results in a very challenging situation. Laparoscopic surgery versus open surgery for colon cancer: Best supportive care; 5-FU: Real time contrast enhanced ultrasonography in detection of liver metastases from gastrointestinal cancer.
Also owing to the limited penetration in neoplastic tissue, complications including colonic perforation, are presumably lower than that reported after Nd: Palliative ileocecal resection ccolon considered a low-complexity, short-lasting procedure which may be accomplished even under spinal anaesthesia, thus reducing the stress of surgery.
Prospective, randomized trial of intravenous versus intraperitoneal 5-fluorouracil in patients with advanced primary colon or rectal cancer. In order to anchor the stent and to prevent any migration, colonic stents are usually clepsydra-shaped and may have various diameters and length in order to fit any neoplastic stricture.
A prospective evaluation of short-term and long-term results from colonic stenting for palliation or as a bridge to elective operation versus immediate surgery for large-bowel obstruction. Outcome and natural history of patients with stage IV colorectal cancer receiving chemotherapy without primary tumor resection.
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. The clinical benefit of colln in metastatic colorectal cancer is independent of K-ras mutation status: Limits of past and present literature First appeared in scientific literature in the mid-twentieth century[ 4647 ], the management of incurable metastatic CRC still represent a matter of debate among oncologists, and surgeons.
Randomized trial comparing monthly low-dose leucovorin and fluorouracil bolus with bimonthly high-dose leucovorin and fluorouracil bolus plus continuous infusion for advanced colorectal cancer: Late stent occlusion is usually due to cancer progression and colonization of stent neo-lumen, and therefore is manageable endoscopically and suitable of re-stenting or laser ablation.
Primary tumor resection in patients presenting volon metastatic colorectal cancer: Moreover, perforation may cause the aaskep diffusion of CRC by dissemination of neoplastic cells[ ]. Palliative radiotherapy in patients with a symptomatic pelvic mass of metastatic colorectal cancer.
Differently, in emergency and severely symptomatic patients, it is focused in solving cancer-related complications, cloon may be rapidly fatal or imply intolerable symptoms. Palliative resection of colorectal cancer: 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.
Staging of peritoneal carcinomatosis: Several others askepp have been found to be related to a poor prognosis or poor surgical outcome, thus being considered to be arguments against major surgical resection. The choice of derivative surgery also depends on tumor characteristics and location indeed, being any internal by-pass non possible for tumors arising distally to the sigmoid colon.
Palliative care and end-stage colorectal cancer management: The surgeon meets the oncologist
Preoperative portal vein embolization for extended hepatectomy. Transanal endoscopic versus total mesorectal laparoscopic resections of T2-N0 low rectal cancers after neoadjuvant treatment: Laparoscopic versus conventional palliative resection for incurable, symptomatic stage IV colorectal cancer: Prolonged survival of initially unresectable hepatic colorectal cancer patients treated with hepatic arterial infusion of oxaliplatin followed by radical surgery of metastases.
Although any generalization is difficult, two main situations are considered, asymptomatic or minimally symptomatic and severely symptomatic patients needing aggressive management, including emergency cases. Although it is not among the aims of the present paper, imaging modalities for resectability assessment are briefly summarized. Stage and size using magnetic resonance imaging and endosonography in neoadjuvantly-treated rectal cancer.
As reported before, resection is generally proposed for proximal tumors, whereas it is attentively pondered for rectal tumors see above for surgical options. Operation in patients with incurable colon cancer–is it worthwhile.
