Population-based audit of colorectal cancer management in two UK health regions. In general, it should be copon that any complication, even minor, may significantly affect the short residual life.
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.
Initial presentation with stage IV colorectal cancer: Transanal procedures are discussed in the paragraph dedicated to bleeding and other symptoms. Randomized clinical trial comparing loop ileostomy and loop transverse colostomy for faecal diversion following total mesorectal excision.
Last but not least, the positive psychological effect of not having a temporary or permanent colostomy is another positive effect of stent positioning[ ]. Bleeding and other symptoms pain, tenesmus are managed mini-invasivally by radiotherapy, laser therapy and other transanal procedures. The main limitations of RT is the recurrence askfp symptoms in roughly one half of the patients within 6 mo[ 59]; thus, it is best indicated in short survivors[ 59 ].
New agents have already showed promising results after the failure of conventional CHT.
Endoscopic transanal resection provides palliation equivalent xolon transabdominal resection in patients with metastatic rectal cancer. Supported by University of Parma Research Funds. Severe complications limit long-term clinical success of self-expanding metal stents in patients with obstructive colorectal cancer.
Perforations resulting in localized abscesses may also be managed by surgical drainage of the collection or US- or CT-scan guided procedure. The indication to surgical resection of other extrahepatic CRC disease, in particular peritoneal metastasis, is also matter of debate: 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 ].
Higher perioperative mortality and morbidity of CRC resection represent the counterpart of a supposed longer survival. MRI is reported to be superior to CT in the preoperative evaluation of colorectal metastasis both in normal liver[ 35 ], where it has higher sensitivity Modern self-expandable metallic stents are conceived to be incorporated into the tumor by exercising a pressure and inducing a partial necrosis in surrounding neoplastic tissue.
Secondary surgery of liver metastasis is gaining acceptance since, under new generation CHT regimens, an increasing amount of patients with distant metastasis initially considered non resectable become resectable, with a significant increase in long term survival.
First appeared in scientific literature in the mid-twentieth century[ 4647 ], the management of incurable metastatic Cca still represent a matter of debate among oncologists, and surgeons.
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. Indeed, unless the patient presents the typical features of acute obstruction or acute diffuse peritonitis by colonic perforation, it is often difficult to assess the real threaten to life and consequently the real need and timing of emergency surgery in the case of patients with a very limited life expectancy.
Oral capecitabine compared with intravenous fluorouracil plus leucovorin in patients with metastatic colorectal cancer: Palliative resection for colorectal carcinoma.

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[ ]. Palliative operations for colorectal cancer. Palliative surgery for cancer of the rectum and colon. 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.
Significantly, a high rate of severe complications following stage IV CRC stenting led to the early closure of a multicenter trial[ ]. Management of stage IV rectal cancer: Medical treatment for colon cancer has been radically modified in its aims and modalities in the last 30 years: Early closure of a multicenter randomized clinical trial of endoscopic stenting versus surgery for stage IV left-sided colorectal cancer.
During this long period of time, chemotherapy was considered as a palliative treatment and was administered only when surgery was no longer possible due to the presence of locally advanced or metastatic disease. Although encouraging, the retrospective nature of present literature on the subject prevents from definitive conclusions.
Ther Adv Med Oncol. Nevertheless, CRC stent has peculiar contraindications and complications, and its long-term cost-effectiveness is questionable, especially in the light of recently increased survival.
