Multifaceted therapeutic options, ranging from open surgery to minimally invasive techniques, from traditional CHT to new molecular targets, has allowed for a dramatic increase in expected survival from mo with best supportive care to more than two years, mostly due to the introduction and diffusion of new and increasingly effective CHT agents.

National Center for Biotechnology InformationU. Palliative resections in cancer of the colon and rectum.

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: YAG and endocavitary radiation in the palliation of rectal cancer.

Bleeding and other symptoms pain, tenesmus are managed mini-invasivally by colkn, laser therapy and other transanal procedures. Therefore, it is difficult to make any generalization and any patient should be evaluated on a case by case basis.

Palliative radiotherapy in patients with a symptomatic pelvic mass of metastatic colorectal cancer. Medical treatment for colon cancer has been radically modified in its aims and modalities in the last 30 years: Resection of the primary tumour or other palliative procedures in incurable stage IV colorectal cancer patients.

Obviously, the main purpose ac surgery for colonic perforation is not avoiding colonic leak, since stools have already diffused in the abdomen, nor performing an oncologically complete lymphadenectomy. Stage and size using magnetic resonance imaging and endosonography in neoadjuvantly-treated rectal cancer. A randomized controlled trial of fluorouracil plus leucovorin, irinotecan, and oxaliplatin combinations in patients with previously untreated metastatic colorectal cancer.

On the contrary, left-sided procedures are more time-consuming and associated to higher morbidity[ 75 ], including leakage and pelvic abscess[ 76 ]. Differently, in emergency and severely symptomatic patients, it is focused in solving cancer-related complications, which may be rapidly fatal or imply intolerable colkn.

Differently from procedures achieving an R0 resection no residual neoplastic tissue left after resectionleaving residual neoplastic tissue R1, R2 is related to the same dismal prognosis as no resection[ 5 ]. In patients presenting without significant clinical symptoms or emergency conditions, the main question is whether they may benefit from primary CRC resection or a less aggressive management should be preferred.

Normally performed in the transverse colon or sigma, stoma fashioning may be preceded by laparoscopic exploration, which can facilitate the dissection of the chosen segment and the identification of the colostomy placement[ 69 ].

Moreover, prolonging survival, CHT is somehow changing the perspective concerning the best long-term management of primary CRC complications, possibly challenging the role of short-lasting, mini-invasive approaches stenting, local treatments, J Natl Compr Canc Netw.

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. Severe complications limit long-term clinical success of self-expanding metal stents in patients with obstructive colorectal cancer. Liver metastases from colorectal cancer: Oral capecitabine compared with intravenous fluorouracil plus leucovorin in patients with metastatic colorectal cancer: 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.

Intestinal complications after palliative treatment for asymptomatic patients with unresectable stage IV colorectal cancer. From the eighties to the nineties, with studies on fluoropyrimidines, some steps have been made towards a chemotherapeutic regimen active in advanced CRC[ 9- ]. Traditionally approached surgically, by resection of the primitive tumor or stoma, the management 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.

Palliative management for patients with subacute obstruction and stage IV unresectable rectosigmoid cancer: Abdominal pain and tenesmus are also observed both perioperatively and as a late complication, and are generally managed conservatively[, ]. 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.

Laser therapy and endocavitary radiation: Since then, stent use has been proposed with three purposes: Population-based audit of colorectal cancer management in two UK health regions. In general, it should be reminded that any complication, even minor, may significantly affect the short residual life.

World J Surg Oncol. 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.

Palliative care and end-stage colorectal cancer management: The surgeon meets the oncologist

Resective surgery for palliation[ 27477071 ] include classic procedures performed for CRC, such as right colectomy, left colectomy, Hartmann procedure left segmental colectomy associated with proximal stump colostomy and closure of the distal stumpproctocolectomy, low anterior resection and abdominoperineal resection.

Moreover, perforation may cause the transcelomatic diffusion of CRC by dissemination of neoplastic cells[ ].

Significantly, in their systematic review of papers comparing survival of patients undergoing askrp resection vs non-resection of the primary tumor, Verhoef et al[ 82 ] found that the resection of primary CRC was related to better prognosis in all papers including no or very few patients undergoing CHT[ 274779 ], whereas results were more ambiguous in series including patients askpe CHT, where resective surgery resulted as being related to survival in some papers[ 5083 – 85 ] but not in others[ 485253617086 ].

In particular, bevacizumab a humanized antibody anti-circulating vascular endothelial growth factor – VEGF-A and cetuximab a recombinant antibody anti- epidermal growth factor receptor – EGFR have been introduced in advanced CRC in association with poli-chemotherapic regimens. Fluorouracil, leucovorin, and oxaliplatin with and without cetuximab in the first-line treatment of metastatic colorectal cancer.

Liver resection for colorectal cancer metastases. Assessment of resectabilty or palliation Although it is not among the aims of the present paper, imaging modalities for resectability assessment are briefly summarized. Surg Laparosc Endosc Percutan Tech. Extrahepatic disease does not contraindicate hepatectomy for colorectal liver metastases.
