Abstract
AIM The incidence, patterns of care and survival were determined in patients with stage IV colorectal cancer (CRC) in a population-based series. METHOD Computer records for patients diagnosed with stage IV CRC diagnosed from 1 January 1995 to 31 December 2007 were retrieved from the Rotterdam Cancer Registry. Surgical resection of the primary tumour, chemotherapy use, hepatic surgery and survival were evaluated according to year of diagnosis, age, gender and primary tumour site. RESULTS In the southwestern part of the Netherlands, 19 014 new patients with CRC were diagnosed and synchronous metastatic disease was found in 3482 (18%). This proportion increased during the study period, from 16% to 21%. Surgical resection of the primary tumour was performed in approximately 50% of the patients and did not change over time. Postoperative 30-day mortality was 8%. Chemotherapy use increased from 18% in the first period to 56% in the latest period. Liver surgery increased from 4% in the first period to 10% in the latest period. Median survival increased from 7 months to 12 months and 2-year survival increased from 14% to 28%. Two-year survival declined with increasing age and was significantly worse for right-sided tumours (14%). CONCLUSION Survival of patients with stage IV CRC has improved over time and this is probably a result of the increased use of chemotherapy and the increased numbers of patients who underwent hepatic surgery.

Abstract
UNLABELLED Optimal management of asymptomatic generalized rectal cancer is still the matter of debate. The aim of the study was to review stage IV rectal cancer patients who were treated in our clinic since 2000 till 2008 in order to evaluate the effectiveness of surgery. MATERIAL AND METHODS Fifty-two generalized rectal cancer patients treated with elective resection of primary tumor were identified. Patients' age, sex, duration of hospital stay, modality of surgery, complications, postoperative mortality rate and survival rate were assessed. RESULTS Median survival was 16.3 months. Postoperative complications occurred in 29% patients. Postoperative mortality rate was 1.9%. CONCLUSIONS In properly selected group of patients elective resection of primary tumor may cause low mortality rate and acceptable morbidity rate. This surgical modality allows to avoid potential complications of tumor local growth.

Abstract
In patients with symptomatic incurable metastatic colorectal cancer (mCRC), the goal of resection of the primary lesion is to palliate cancer-related morbidity, including obstruction, bleeding, or perforation. In patients with asymptomatic primary tumors and incurable metastatic disease, however, the necessity of primary tumor resection is less clear. Although several retrospective analyses suggest survival benefit in patients who undergo resection of the primary tumor, applying this older evidence to modern patients is out of date for several reasons. Modern chemotherapy regimens incorporating the novel cytotoxic agents oxaliplatin and irinotecan, as well as the target agents bevacizumab and cetuximab, have improved median survival from less than 1 year with the only available single-agent 5-fluorouracil until the mid-1990s to over 2 years. In addition to significant prolongation of overall survival, combinations of novel chemotherapeutic and target agents have allowed improved local and distant tumor control, decreasing the likelihood of local tumor-related complications requiring surgical resection. Resection of an asymptomatic primary tumor risks surgical complications and may postpone the administration of chemotherapy that may offer both systemic and local control. In conclusion, the morbidity and the mortality of unnecessary surgery or surgery that does not improve quality of life or survival in patients with mCRC of a limited life expectancy should be carefully evaluated. With the availability of effective combinations of chemotherapy and target agents, systemic therapy for the treatment of life-threatening metastases would be a preferable treatment strategy for unresectable asymptomatic patients with mCRC.

Abstract
In the absence of symptoms, primary tumor resection in patients who present with unresectable metastatic colorectal cancer is of uncertain benefit. Prophylactic surgery has been traditionally considered in this setting in order to prevent subsequent complications of perforation, obstruction, or bleeding later during the treatment course, which may require urgent surgery associated with higher mortality. However, recent data have called into question the efficacy of this upfront surgical strategy. We provide a brief overview of how current combinations of systemic chemotherapy including fluorouracil, oxaliplatin, irinotecan, and targeted biologic agents have allowed improved local (in addition to distant) tumor control, significantly decreasing the incidence of late primary-related complications requiring surgery from roughly 20% in the era of single-agent fluoropyrimidine chemotherapy to almost 7% in the era of modern triple-drug chemotherapy. In addition, we attempt to highlight those factors most associated with subsequent primary tumor-related complications in an effort to identify the subset of patients with synchronous metastatic colorectal cancer who might benefit from a surgery-first approach. Finally, we discuss modern nonsurgical options available for palliation of the primary colorectal tumor and review the outcome of patients for which emergent surgery is eventually required to address primary-related symptoms.

Abstract
Background In patients with metastatic colorectal cancer (mCRC) with an asymptomatic primary tumor, there is no consensus on the indication for resection of the primary tumor. Methods A retrospective analysis was performed on the outcome of stage IV colorectal cancer (CRC) patients with or without resection of the primary tumor treated in the phase III CAIRO and CAIRO2 studies. A review of the literature was performed. Results In the CAIRO and CAIRO2 studies, 258 and 289 patients had undergone a primary tumor resection and 141 and 159 patients had not, respectively. In the CAIRO study, a significantly better median overall survival and progression-free survival was observed for the resection compared to the nonresection group, with 16.7 vs. 11.4 months [P < 0.0001, hazard ratio (HR) 0.61], and 6.7 vs. 5.9 months (P = 0.004; HR 0.74), respectively. In the CAIRO2 study, median overall survival and progression-free survival were also significantly better for the resection compared to the nonresection group, with 20.7 vs. 13.4 months (P < 0.0001; HR 0.65) and 10.5 vs. 7.8 months (P = 0.014; HR 0.78), respectively. These differences remained significant in multivariate analyses. Our review identified 22 nonrandomized studies, most of which showed improved survival for mCRC patients who underwent resection of the primary tumor. Conclusions Our results as well as data from literature indicate that resection of the primary tumor is a prognostic factor for survival in stage IV CRC patients. The potential bias of these results warrants prospective studies on the value of resection of primary tumor in this setting; such studies are currently being planned.

Abstract
BACKGROUND With the improvements in newer chemotherapeutic agents, the role of primary tumour resection in patients with stage IV colorectal cancer is controversial. In many cases primary tumour resection is still favoured as first-line management. However, a detailed understanding of independent prognostic factors related to survival is necessary before making this decision. METHOD A literature search was conducted using Medline and Embase. Studies that performed multivariate analysis on overall survival of patients with incurable stage IV colorectal cancer were included in this review. RESULTS Fourteen retrospective studies involving 3209 patients were included. Clinical variables analysed to consistently have independent prognostic significance for long-term survival included the patients' performance status (<2), volume of liver metastases (<50%), nodal stage (N0), disease-free resection margins, and treatment with chemotherapy and/or primary tumour resection. Cancer antigen (CA) 19-9, low albumin, elevated ALP levels, apical lymph node involvement, presence of ascites, and postoperative transfusion were each assessed by only one study and found to be independently associated with survival. Factors inconsistently reported to have independent prognostic significance were age, ASA score, preoperative CEA levels, primary tumour location, tumour size and differentiation, peritoneal dissemination, and extrahepatic metastases. CONCLUSION Each patient should be reviewed individually on the basis of the above independent prognostic factors before deciding to resect the primary tumour. Patients with a poor performance status, extensive hepatic metastases, and extensive nodal disease detected preoperatively are less likely to have a survival benefit. Nonsurgical approaches to manage these patients should be given careful consideration.

Abstract
The start of chemotherapy treatment usually requires a delay of about 4 weeks after surgical resection in patients with primary colorectal cancer and synchronous distant metastasis. However, there is no evidence to indicate the required length of this delay interval. In addition, there is a chance that a patient may die because postoperative chemotherapy was not started soon enough and a metastatic tumor was able to develop rapidly. Here, we present a case in which combination chemotherapy with capecitabine and oxaliplatin (XELOX) was started within 1 week after a right hemicolectomy for synchronous multiple liver metastases. To our knowledge, this is the first report of the start of chemotherapy, involving treatments such as folinic acid, fluorouracil, and oxaliplatin (FOLFOX); folinic acid, fluorouracil, and irinotecan (FOLFIRI); and XELOX, within 1 week after a colorectal cancer operation with anastomosis. The findings suggest possible changes in the start time of chemotherapy after surgery in the future.

Abstract
Approximately 30% of patients with rectal cancer present with metastatic disease. Many of these patients have symptoms of bleeding or obstruction. Several treatment options are available to deal with the various complications that may afflict these patients. Endorectal stenting, laser ablation, and operative resection are a few of the options available to the patient with a malignant large bowel obstruction. A thorough understanding of treatment options will ensure the patient is offered the most effective therapy with the least amount of associated morbidity. In this review, we describe various options for palliation of symptoms in patients with metastatic rectal cancer. Additionally, we briefly discuss treatment for asymptomatic patients with metastatic disease.

Abstract
PURPOSE Despite the encouraging results of chemotherapy in patients affected by incurable colorectal cancer (CRC), surgical resection of a primitive tumor is still a common approach worldwide. The identification of prognostic factors related to short survival (<6 months) may allow excluding from resective surgery those who may not benefit from it. METHODS A retrospective analysis was performed of 15 variables in a population of 71 patients undergoing nonemergency palliative primary resections of incurable CRC, including patients' demographics and clinical/histopathological characteristics of the tumor. RESULTS No variables were related to perioperative mortality (8.5% overall). A multivariate analysis revealed that older age (≥80 years) and metastasis to more than 25% of the lymph nodes were associated with survival (4 and 6 months, respectively). Mucoid adenocarcinoma therefore tends to be associated with the prognosis (P = 0.070). CONCLUSIONS An elderly age tends to be a contraindication to an elective primary tumor resection in patients affected by incurable CRC. Massive lymph node involvement and mucoid adenocarcinoma should also be considered before planning major colonic surgery.

Abstract
OBJECTIVE Nonresectional palliative abdominal surgery (e.g. defunctioning stoma/bypass) may be appropriate for patients unsuitable for curative resection, to deal with complications of advanced colorectal malignancy such as obstruction. Our aim was to review the outcome of surgery in these patients within our institution. METHOD All patients undergoing palliative surgery without resection for colorectal carcinoma between July 1998 and January 2007 were identified from our prospectively compiled colorectal cancer database. Data were extracted related to patients' demographics, presentation, tumour site, operative intervention, complications, oncological therapies, length of hospital stay and postoperative survival. RESULTS One hundred and ninety-three patients were identified with a median age of 79 years (31-94 years). Fifty per cent were operated on an emergent basis for obstruction or perforation, and 50% on an elective basis. One hundred and sixty-nine patients had defunctioning stomas formed of which 156 were loop stomas. Twenty-four patients underwent bypass procedures. Thirty-day mortality rate was 13.5% and postoperative morbidity rate 47%. Median survival was 247 days, with 1-year survival of 38%. Patients undergoing operation on an emergent basis had poorer long-term survival (127 vs 320 days, P = 0.002). CONCLUSION Nonresectional palliative abdominal surgery is associated with relatively high morbidity and mortality, particularly when performed in the emergency setting. However, in this patient group with a very poor outlook, it may be offered with reasonable survival expectations.

Abstract
AIM: To investigate survival in patients treated with FOLFOX followed by primary site resection or palliative surgery for incurable metastatic colorectal cancer.
METHODS: Between 2001 and 2009, a total of 98 patients with colorectal adenocarcinoma and non-resectable metastases were diagnosed and treated with the new systemic agent chemotherapy regimen FOLFOX. Primary site resection was carried out in 38 patients, creation of a colostomy or bypass without resection was carried out in 36 patients, and 23 were not operated on because of advanced disease. The survival times of patients in different groups were analyzed.
RESULTS: There were no differences between the patients regarding their general condition, concurrent disease, or tumor stage according to AJCC classification. The median survivals of the three groups were 30.6, 20.8, and 12.7 mo (log-rank P value < 0.05), respectively. The postoperative complication rate was higher in the primary site resection group than in the palliative surgery group.
CONCLUSION: The results indicate that there are benefits from primary site resection for incurable metastatic colorectal cancer with systemic chemotherapy.

Abstract
BACKGROUND The initial surgical management of asymptomatic patients with unresectable stage IV colorectal cancer (CRC) is still controversy. The aim of this study was to compare the incidence of major intestinal complications in asymptomatic patients who received palliative treatment for unresectable stage IV CRC, according to the type of treatment. METHODS Between March 2001 and January 2008, we retrospectively analyzed 227 asymptomatic patients who underwent first-line resection of the primary tumor followed by chemotherapy (144 patients, resection group) or those who underwent first-line chemotherapy (83 patients, chemotherapy group). RESULTS In the resection group, the incidences of intestinal obstruction, peritonitis, fistula, and intestinal hemorrhage were 14.6%, 0%, 0.7%, and 4.8%, respectively. In the chemotherapy group, these incidences were 15.2%, 1.2%, 0%, and 3.5%, respectively. There were no significant differences between the two groups in terms of intestinal complications. In multivariate analysis of overall survival, treatment type (resection group vs. chemotherapy group) was not a significant prognostic factor (P = 0.076). CONCLUSIONS In asymptomatic patients with unresectable stage IV CRC, first-line chemotherapy may be considered safe, with no increased risk of major intestinal complications compared with primary tumor resection plus chemotherapy.

Abstract
BACKGROUND There is no consensus regarding the appropriate management of asymptomatic and minimally symptomatic patients with stage IV colorectal cancer and irresectable metastases. METHODS A literature search was conducted on Medline and Embase. Outcome measures included: survival; postoperative morbidity and mortality; complications from the primary tumor and the need for surgery to manage complications; the likelihood of curative surgery after initial response to primary therapy; and length of hospital stay. Quantitative meta-analysis was performed where appropriate. RESULTS Eight retrospective studies, including 1,062 patients, met the criteria for inclusion in this study. Meta-analysis has shown an improvement in the survival of patients managed with palliative resection of their primary tumor, with an estimated standardized median difference of 6.0 months (standardized difference, 0.55; 95% confidence interval (CI), 0.29, 0.82; p < 0.001). Patients managed with chemotherapy alone were 7.3 times more likely to have a complication from the primary tumor (95% CI, 1.7, 34.4; p = 0.008). There was no difference in the response rates to chemotherapy, making metastatic disease amendable to curative resection (0.85; 95% CI 0.40, 1.8; p = 0.662). CONCLUSIONS To date, only retrospective data are available, showing that palliative resection of the primary tumor in asymptomatic or minimally symptomatic patients with stage IV colorectal cancer is associated with longer survival. Resection of the primary tumor reduces the likelihood of complications from the primary tumor and avoids the need for emergency procedures.

Abstract
BACKGROUND Recent trials proposed chemotherapy (CHT) as the treatment of choice for patients affected by incurable colorectal cancer (ICRC). Nevertheless, surgery is still commonly offered to these patients. On the other hand, CHT is offered to ICRC patients regardless of the pattern of spread of the disease, local or distant, despite some evidence suggesting that metastatic pattern may influence the response to treatment. METHODS A retrospective analysis was performed of 133 patients undergoing palliative treatment for ICRC from 1994 through 2007. Palliation consisted of surgery alone until 2002 and surgery with CHT (FOLFOX-FOLFIRI) thereafter. The impact of CHT and surgery was evaluated in the whole series as well as with respect to metastatic pattern (locally aggressive primary tumor and distant metastasis only), tumor site, and grading. RESULTS Chemotherapy prolonged survival by 9 months (p = 0.001). In patients undergoing CHT, resective surgery did not prolong survival (p = 0.931), whereas in patients not undergoing CHT, it improved prognosis by 5 months (p = 0.023). Considering patients with distant metastasis only, CHT significantly prolonged survival (p < 0.001), whereas it did not improve the prognosis of patients with a locally aggressive primary tumor (p = 0.943). No difference in CHT effectiveness with respect to tumor site and grading was recorded. CONCLUSIONS CHT should be the preferred option in patients undergoing elective treatment for ICRC, whereas surgery should be considered whenever CHT is not administered. CHT significantly increases survival of patients with unresectable distant metastasis only, whereas it seems to be useless in patients with locally aggressive primary tumors.

Abstract
INTRODUCTION Approximately 20% of patients with colorectal cancer have metastases at the time of presentation. Such patients are often offered systemic chemotherapy but debate continues as to whether these patients benefit from resection of the primary tumour. We describe our ten years experience of managing the primary tumours in patients with stage IV colorectal cancer. The aim of this study was to describe the overall survival of patients undergoing surgery in these circumstances and to determine whether any prognostic indicators could be identified. PATIENTS & METHODS 920 consecutive patients presenting with stage IV colorectal cancer disease were identified from the Leicester Colorectal Cancer database. Patients undergoing resection of the primary tumour (Resection Group) with the residual metastatic disease were compared to those patients who had not their primary tumour excised (Non-Resection Group). Various different variables in two groups were compared by using Mann-Whitney U test. Kaplan-Meier survival analysis and log-rank test were used to compare the overall survivals. Univariate analysis was performed for each group to elicit the significant prognostic factors whereas Cox regression model was used to identify the independent predictors of overall survival. RESULTS The Kaplan-Meier survival analysis of two groups showed prolonged survival for Resection Group compared to the Non-Resection Group (median; 14.5 Vs 5.83 months, p = <0.005). The multivariate analysis of different survival predicting variables, revealed the resection of the primary tumour as an independent predictor of overall survival (p < 0.001). The univariate analysis of resection group identified age at presentation, tumour site, tumour stage (pT), lymph nodal stage (pN), complete histological resection, tumour fixity, ASA grade, mode of surgery, post-operative chemotherapy and sites of metastasis as significant factors (p < 0.05) for survival prediction. When these factors were used in Cox-Regression model, only the age at presentation (p = 0.001), tumour fixity (p = 0.012) and lymph nodal involvement (p = 0.042) were independent predictors for overall survival. Treatment with post-operative chemotherapy and a smaller volume of liver metastases were associated with prolonged survival (p < 0.05). CONCLUSIONS Surgical resection of primary tumour for stage IV colorectal cancers is associated with prolonged survival for selected patients. Age at presentation, extent of liver involvement, tumour fixity and ASA grade can help to decide the patients who will benefit from surgery.

Abstract
INTRODUCTION In the setting of stage-IV obstructive colorectal cancer, self-expanding metallic stents (SEMS) placement and palliative surgery may be appropriate options. The aim of the present study is to evaluate the long-term results of surgery compared with stent implantation and to identify patients in whom one of these options can provide more benefit. MATERIALS AND METHODS From November 2000 to November 2008, 98 patients with incurable stage-IV colorectal cancer were treated with palliative surgery (n=53) or SEMS (n=45). Data were recorded with respect to age, gender, tumor location, carcinoembryogenic antigen, ASAclass, presence of metastatic disease in one or multiple organs, volume of liver metastases, urgency of the procedure and treatment with chemotherapy. Comparison between surgery and stent placement was performed for all group and for patients who received and did not receive chemotherapy. RESULTS Both groups were comparable regarding age, ASA-class, chemotherapy treatment, tumor location and presence of metastatic disease in one or multiple organs but not in gender, rate of urgent procedures, abnormal CEA and of volume of liver metastases >25%. Survival in surgical group was significantly higher (11.9 vs 7.3 months; log-rank test, p = 0.002). SEMS group had lower early morbidity, hospital stay and stoma creation. For patients who received chemotherapy, surgery provided benefit in survival (6.8 vs 3.9 months; log-rank test, p = 0.101); in this subgroup, long-term complications from the primary tumour were more common in stented group, and time to chemotherapy was longer in the group of surgery. No differences in survival were shown in patients who did not receive chemotherapy. CONCLUSION Stent placement offers advantages regarding early morbidity, hospital stay and stoma creation. Surgery offers a benefit in survival in patients who receive chemotherapy but not in non-candidates to chemotherapy.

Abstract
AIM Management of patients with irresectable stage IV colorectal cancer is controversial. Since 2000, we have favoured primary chemotherapy with stent insertion in case of obstructive tumor. Our aim was to report the results of this strategy in an unselected consecutive series of patients. PATIENTS AND METHODS From 2000 to 2007, 68 of 115 consecutive patients admitted with stage IV colorectal cancer were considered irresectable. Data were collected prospectively. Feasibility and outcomes were analysed in an intention to treat basis. RESULTS Of 68 patients, 37 received the intended primary chemotherapy, with stent insertion in 19, 13 required surgery as initial management and 18 patients received supportive care only. Twelve patients in the primary chemotherapy group developed local complication, including bowel obstruction in 9, successfully managed by stent in 6 of them. In patients requiring surgery at presentation, mortality and morbidity were 31% and 77%, respectively. Overall, 41 patients received chemotherapy, of whom, 6 were downstaged to undergo curative resection. Median survival was 6.7 and 15.4 months for the whole series and patients treated by primary chemotherapy, respectively (p<0.0001). On multivariate analysis, age, CEA level, primary chemotherapy and secondary curative resection were independently associated with survival. CONCLUSION In unselected patients with irresectable stage IV colorectal cancer, primary chemotherapy with or without stent is feasible in more than 50% of cases and is associated with a low rate of secondary surgery for complicated primary tumor. This strategy may represent the best palliation in these patients for both duration and quality of survival.

Abstract
Asymptomatic patients with metastatic colorectal cancer do not routinely need to undergo resection of the primary tumor. Although several retrospective analyses suggest that patients who undergo resection of the primary tumor live longer, most of these reviewed data prior to the advent of modern polychemotherapy and are subject to considerable bias, as patients who were considered able to undergo surgery likely had better overall prognoses than those who were not. In addition to significant prolongation of overall survival, current combinations of systemic chemotherapeutic agents and targeted agents have allowed improved local and distant tumor control, decreasing the likelihood of local tumor-related complications requiring colon resection.

Abstract
OBJECTIVE The management of the asymptomatic primary in stage IV colorectal cancer presents a dilemma. There is an increased morbidity and mortality from surgical resection. Nonresectional management of the primary is associated with the risks of obstruction, perforation or haemorrhage. Our practice in patients with stage IV disease is palliative chemotherapy and symptom control. We reviewed our nonoperatively managed patients with colorectal liver metastases in order to identify the percentage of patients requiring urgent operative interventions for symptoms related to the primary. SUBJECTS/PATIENTS AND METHOD: A retrospective review of all patients treated for stage IV disease at our institution from 2003-2006 was undertaken. Patients were identified from multidisciplinary team (MDT) records. Demographic detail, treatment, and follow-up data were extracted from hospital records. These were analysed with Microsoft Excel. RESULTS Thirty-seven patients were identified. 26 Male:11 Female. Median age 63 years (range 38-78). The median survival from diagnosis was 14 months. Three (8%) patients developed obstruction whilst having palliative chemotherapy. Two required a defunctioning stoma, and one was treated by means of a stent. There were no similarities between these three patients in terms of age, sex, site or stage of primary, volume of liver metastases, and alkaline phosphatase (ALP) or carcinoembryonic antigen (CEA) levels. CONCLUSION Of 37 patients initially treated palliatively for stage IV colorectal cancer, 92% required no surgical treatment of their primary. Therefore it is the experience of this MDT that it is acceptable to treat such patients in an expectant manner. It is not possible to predict those patients, likely to require surgical intervention.

Abstract
PURPOSE The benefit of elective primary tumor resection for non-curable stage IV colorectal cancer (CRC) remains largely undefined. We wanted to identify risk factors for postoperative complications and short survival. METHODS Using a prospective database, we analyzed potential risk factors in 233 patients, who were electively operated for non-curable stage IV CRC between 1996 and 2002. Patients with recurrent tumors, resectable metastases, emergency operations, and non-resective surgery were excluded. Risk factors for increased postoperative morbidity and limited postoperative survival were identified by multivariate analyses. RESULTS Patients with colon cancer (CC = 156) and rectal cancer (RC = 77) were comparable with regard to age, sex, comorbidity, American Society of Anesthesiologists score, carcinoembryonic antigen levels, hepatic spread, tumor grade, resection margins, 30-day mortality (CC 5.1%, RC 3.9%) and postoperative chemotherapy. pT4 tumors, carcinomatosis, and non-anatomical resections were more common in colon cancer patients, whereas enterostomies (CC 1.3%, RC 67.5%, p < 0.0001), anastomotic leaks (CC 7.7%, RC 24.2%, p = 0.002), and total surgical complications (CC 19.9%, RC 40.3%, p = 0.001) were more frequent after rectal surgery. Independent determinants of an increased postoperative morbidity were primary rectal cancer, hepatic tumor load >50%, and comorbidity >1 organ. Prognostic factors for limited postoperative survival were hepatic tumor load >50%, pT4 tumors, lymphatic spread, R1-2 resection, and lack of chemotherapy. CONCLUSIONS Palliative resection is associated with a particularly unfavorable outcome in rectal cancer patients presenting with a locally advanced tumor (pT4, expected R2 resection) or an extensive comorbidity, and in all CRC patients who show a hepatic tumor load >50%. For such patients, surgery might be contraindicated unless the tumor is immediately life-threatening.

Abstract
PURPOSE The purpose of this study was to describe the frequency of interventions necessary to palliate the intact primary tumor in patients who present with synchronous, stage IV colorectal cancer (CRC) and who receive up-front modern combination chemotherapy without prophylactic surgery. PATIENTS AND METHODS By using a prospective institutional database, we identified 233 consecutive patients from 2000 through 2006 with synchronous metastatic CRC and an unresected primary tumor who received oxaliplatin- or irinotecan-based, triple-drug chemotherapy (infusional fluorouracil, leucovorin, and oxaliplatin; bolus fluorouracil, leucovorin, and irinotecan; or fluorouracil, leucovorin, and irinotecan) with or without bevacizumab as their initial treatment. The incidence of subsequent use of surgery, radiotherapy, and/or endoluminal stenting to manage primary tumor complications was recorded. RESULTS Of 233 patients, 217 (93%) never required surgical palliation of their primary tumor. Sixteen patients (7%) required emergent surgery for primary tumor obstruction or perforation, 10 patients (4%) required nonoperative intervention (ie, stent or radiotherapy), and 213 (89%) never required any direct symptomatic management for their intact primary tumor. Of those 213 patients, 47 patients (20%) ultimately underwent elective colon resection at the time of metastasectomy, and eight patients (3%) underwent this resection during laparotomy for hepatic artery infusion pump placement. Use of bevacizumab, location of the primary tumor in the rectum, and metastatic disease burden were not associated with increased intervention rate. CONCLUSION Most patients with synchronous, stage IV CRC who receive up-front modern combination chemotherapy never require palliative surgery for their intact primary tumor. These data support the use of chemotherapy, without routine prophylactic resection, as the appropriate standard practice for patients with neither obstructed nor hemorrhaging primary colorectal tumors in the setting of metastatic disease.

Abstract
BACKGROUND The treatment of the primary tumor in advanced metastatic colorectal cancer (CRC) is still a matter of discussion. Little attention has thus far been paid to the endoscopically observable changes of the primary in non-curatively resectable stage IV disease. METHODS 20 patients [14 men, 6 women, median age 67 (39-82) years] were observed after initial diagnosis of non-curatively resectable metastasized symptomatic (83%) or asymptomatic (17%) CRC, from June 2002 to April 2009. If necessary, endoscopic tumor debulking was performed. 5-FU based chemotherapy was given immediately thereafter. In 10 patients, chemotherapy was combined with antibody therapy. RESULTS Response of the primary was observed in all patients. Local symptoms were treated endoscopically whenever necessary (obstruction or bleeding), and further improved after chemotherapy was started: Four patients showed initial complete endoscopic disappearance of the primary. In an additional 6 patients, only adenomatous tissue was histologically detected. In both these groups, two patients revealed local tumor relapse after interruption of therapy. Local tumor regression or stable disease was achieved in the remaining 10 patients. 15 patients died during the observation time. In 13 cases, death was related to metastatic disease progression. The mean overall survival time was 19.6 (3-71) months. No complications due to the primary were observed. CONCLUSION This study shows that modern anti-cancer drugs combined with endoscopic therapy are an effective and safe treatment of the symptomatic primary and ameliorate local complaints without the need for surgical intervention in advanced UICC stage IV CRC.

Abstract
BACKGROUND In the absence of symptoms related to their primary tumor, patients with stage IV colorectal cancer can undergo medical treatment with their primary tumor in situ. In these patients, bowel obstruction is the most common primary tumor-related complication. We hypothesized that left-sided, circumferential, near-obstructing lesions and/or inability to advance the colonoscope beyond the primary tumor are associated with symptomatic bowel obstruction and are indications for prophylactic primary tumor resection (PTR) or colonic diversion. PATIENTS AND METHODS The medical oncology database of the University of Wisconsin Hospital was retrospectively reviewed. Inclusion criteria were presentation with stage IV colorectal cancer without previous treatment. Student's t-test and Fisher's exact test were used to compare continuous and noncontinuous variables, respectively. RESULTS Forty-nine patients met the inclusion criteria. None underwent colonic diversion or stenting during the course of their disease. At presentation, nine patients underwent PTR for obstructive symptoms. Forty percent of patients with high-risk colonoscopic lesions required PTR at presentation, compared with 3% of patients without high-risk findings. No patients with high-risk colonoscopic findings and/or left-sided lesions who did not undergo PTR at presentation developed symptoms of obstruction during medical therapy. CONCLUSION In stage IV colorectal cancer, circumferential, near-obstructing lesions and inability to advance the colonoscope beyond the primary tumor are common colonoscopic findings and are associated with obstructive symptoms at the time of diagnosis. Left-sided lesions and/or high-risk colonoscopic findings do not predict bowel obstruction during medical treatment and should not be indications for prophylactic PTR or colonic diversion in asymptomatic patients.

Abstract
BACKGROUND The management of patients with surgically incurable bowel cancer at presentation is controversial. The aims of treatment are to optimise quality of life and prolong survival. It has been believed that the most effective palliation is achieved by resection of the primary cancer in order to pre-empt future complications. This study reviews and compares the outcomes of patients with incurable bowel cancer managed by resection and non-resection strategies over a 7-year period in a single District General Hospital. PATIENTS AND METHODS All patients with surgically incurable bowel cancer at presentation were identified from the prospectively collected local ACPGBI database. Survival, using Kaplan-Meier method and log-rank test, was compared between patients managed by resection of the primary, non-resectional intervention (surgery, stent & oncological treatments) and those managed with supportive care only. The primary endpoint of the study was survival on an intention to treat basis, compared using Kaplan-Meier and log-rank tests. RESULTS Of 646 consecutive newly diagnosed bowel cancer patients over a 7 year period 154 cases (24%) were deemed surgically incurable at presentation. Of these surgical resection was carried out in 45 patients (29%), non-resectional intervention was followed in 52 patients (34%) and supportive treatment alone in 57 patients (37%). Median survival of each group was as follows: resected patients 11 months (I.Q range 3-18 months), non-resectional intervention 7 months (I.Q range 2-15 months) and supportive care alone 2 months (I.Q range 1-8 months). Only one patient (2%) managed by non-resectional intervention required later surgery to treat primary tumour related complications. Survival was not significantly different between resection and non-resection treatments. The overall operative mortality for the resection group was 16% (7/45 cases), with an elective mortality of 14% (4/28 cases) and emergency mortality 18% (3/17 cases). CONCLUSION In an unselected bowel cancer population surgical resection of the primary tumour in patients presenting with incurable disease does not improve survival and is associated with a high risk of post-operative mortality.

Abstract
AIM Cancer death in the early period after hepatectomy still occurs in patients with colorectal liver metastasis (CLM). We examined the relationship between clinicopathological parameters and survival periods in 130 CLM patients who underwent hepatectomy. PATIENTS/METHODS Patients were divided into four groups: Group 1 (5-year survivors without tumor relapse), Group 2 (survivors at 2-5 years), Group 3 (cancer death at 2-5 years), and Group 4 (cancer death within 2 years). RESULTS A short surgical margin was frequent in Group 4 compared to Group 1 (31 vs. 78%, P<0.05). Primary node-positive status, absence of fibrous pseudo-capsular formation, higher Clinical Risk Score, and tumor recurrence within 12 months were frequent in Group 4 (P<0.05). Multivariate analysis revealed a short surgical margin (HR; 3.5) and early tumor relapse (HR; 5.9) as independently significant related parameters (P<0.05). CONCLUSIONS Sufficient surgical margins and careful follow-up for early tumor relapse may be important for improving postoperative outcomes for CLM patients.

Abstract
Self-expanding metallic stents (SEMSs) are increasingly used for the palliative treatment of inoperable colorectal cancer. The aim of the current study was to analyze the safety and efficacy of SEMS in the palliative treatment of obstructive colorectal cancer. Between 2003 and 2006, SEMS placement was attempted in 26 patients suffering from inoperable obstructive colorectal cancer. The recovery of the patients and the outcome of this treatment modality were analyzed prospectively. SEMS was successfully inserted in 19 (73%) of 26 patients. In 16 (84%) of these 19 cases, the placement of SEMS was the definitive treatment of colorectal obstruction and no additional surgical palliation was needed. There were 3 (16%) colonic perforations related to stent application. SEMS insertion seems to be an effective alternative in the palliative treatment of patients with malignant colorectal obstruction. However, perforation is a dangerous complication of the procedure.

Abstract
BACKGROUND This study characterizes the histological effect of chemotherapy (CT) on primary colonic tumors. METHODS Between 2000 and 2006, 38 patients with stage IV colon cancer underwent resection of the primary, after chemotherapy (CT group, n = 16) or without preoperative CT (control group, n = 22). For all primary tumors, histological analysis included: fibrosis, acellular necrosis, acellular mucin pools, lymphoplasmacytic infiltration, and changes at tumor surface. Tumor regression grade (TRG) was determined by the amount of residual tumor cells and was graded from 1 to 5. RESULTS No patient had complete histological response. Major histological tumor regression (TRG2) was observed in 70% of patients treated by CT and none of the not treated patients (P < 0.0001). Fibrosis, acellular necrosis, and surface changes were significantly increased in the CT group. TRG in the primary was comparable to the TRG in the corresponding liver metastases for 7/9 patients who underwent both colonic and hepatic resection after CT. CONCLUSION CT induces major histological response in 70% of colon cancers. Response to CT in the primary and the corresponding liver metastases are correlated. These results support a policy of initial CT management for stage IV colon cancer and may warrant future studies of neoadjuvant CT in locally advanced colon carcinomas.

Abstract
OBJECTIVE Self-expanding metal stents are an effective means of relieving left-sided malignant colonic obstruction, and in the setting of incurable disease may provide palliation while allowing the patients to avoid surgery altogether. With modern chemotherapy regimes, patients may have a long-life expectancy, even in the presence of metastases. The purpose of this study was to investigate the long-term results of palliative stent placement, compared with patients undergoing palliative surgery. METHOD This is a retrospective study of 55 consecutive patients who underwent colonic stenting or palliative surgery for incurable, obstructing adenocarcinoma of the left colon. RESULTS Twenty-nine patients underwent colonic stenting, and 26 had surgery during the study period. Survival was similar in the two groups (14 months in the stent group, 11 months in the surgery group). Median hospital stay was shorter in the stent group (4 vs 13.5 days), and fewer patients in the stent group had complications (2 vs 14). Only four patients in the stent group went on to require later surgery. The median time to failure of the stents was 14 months. CONCLUSION Colonic stenting provides effective and durable palliation for patients with incurable, obstructing adenocarcinomas of the left colon. It can be performed with less morbidity than palliative surgery, and offers similar long-term survival.

Abstract
PURPOSE According to the classification system of the Japanese Society for Cancer of the Colon and Rectum, Stage IV colorectal cancer is characterized by distant metastasis, which is defined by four factors: liver metastasis (H factor), metastasis to organs other than the liver (M factor), peritoneal dissemination (P factor), and distant lymph node metastasis (N factor). We conducted this study to investigate the postsurgical prognosis of patients with Stage IV colorectal cancer (CRC), in reference to each of these four factors. METHODS We analyzed the medical records of 73 patients who underwent surgery for Stage IV CRC at our hospital between 1991 and 2001. RESULTS Univariate analysis revealed that P0 or P1 CRC (P < 0.001), absence of the M factor (P = 0.024), well or moderately differentiated adenocarcinoma (P < 0.001), resection of the primary tumor (P < 0.001), and curability B surgery (P < 0.0001) were associated with a better prognosis than other types of Stage IV CRC. Multivariate analysis revealed that tumor differentiation and surgical curability affected cancer-specific survival significantly. CONCLUSION Surgery with curative intent should be considered for patients with Stage IV CRC defined by the P1 factor or H factor.

Abstract
BACKGROUND In patients with asymptomatic colorectal cancer with irresectable metastatic disease, the optimal treatment strategy remains controversial. Resection of the primary tumor followed by chemotherapy when possible versus systemic chemotherapy followed by resection of the primary tumor when necessary are compared in this systematic review. PATIENTS AND METHODS Seven studies reported series of patients with asymptomatic stage IV colorectal cancer and compared first-line chemotherapy with surgery for the primary tumor (n = 850 patients). Primary outcome measure was the complication rate related to the primary tumor in situ in patients receiving first-line systemic chemotherapy. RESULTS When leaving the primary tumor in situ, the mean complications were intestinal obstruction in 13.9% [95% confidence interval (CI) 9.6% to 18.8%] and hemorrhage in only 3.0% (95% CI 0.95% to 6.0%) of the patients. After resection, the overall postoperative morbidity ranged from 18.8% to 47.0%. CONCLUSIONS For patients with stage IV colorectal cancer, resection of the asymptomatic primary tumor provides only minimal palliative benefit, can give rise to major morbidity and mortality and therefore potentially delays beneficial systemic chemotherapy. When presenting with asymptomatic disease, initial chemotherapy should be started and resection of the primary tumor should be reserved for the small portion of patients who develop major complications from the primary tumor.

Abstract
AIM To examine whether surgical resection of the primary tumour confers a survival benefit and to identify the predictive factors of outcome in patients presenting with asymptomatic metastatic colorectal cancer (CRC). MATERIALS AND METHODS A review of a hospital database in a tertiary institution over a 6-year period (1999-2005) revealed 70 patients with asymptomatic primary CRC and unresectable liver metastases treated initially by systemic chemotherapy. A multivariate regression analysis model was used to determine the relative influence of multiple tumours, single/multiple liver metastases, tumour site, differentiation, response of liver and primary tumour to chemotherapy, biochemical response to chemotherapy, age at presentation, performance status and surgical intervention for the CRC primary. RESULTS In 67 cases (3 lost to follow-up), 63 had multiple and 4 single surgically irresectable liver metastases. A total of 41 deaths were recorded. All patients received systemic chemotherapy and surgery was performed for bowel obstruction, bleeding or stable disease (n=32). Surgery (OR 0.26; p=0.00013) and clinical response of the primary tumour (OR 0.53; p=0.012) were independently associated with prolonged survival. Proximal tumours (OR 2.61; p=0.0075) and multiple primaries (OR 3.37; p=0.02) were associated with poor outcome. CONCLUSIONS Surgical resection and response of the primary tumour to chemotherapy may be associated with improved survival, but proximal or multiple cancers predict poor outcome in patients with asymptomatic CRC and unresectable metastatic disease.

Abstract
Several uncertainties surround optimal management of colorectal cancer. We investigated treatment patterns and factors influencing treatment receipt and mortality in routine clinical practice. We included 15 249 individuals, recorded by the National Cancer Registry (Ireland), with primary invasive colon or rectal tumours, diagnosed during 1994–2002. Logistic regression and Cox proportional hazards were used to determine factors associated with treatment receipt within 1 year of diagnosis and with mortality, respectively. A total of 78% had colorectal resection, 31% chemotherapy, and 13% radiotherapy (4% colon; 28% rectum). Half of stage IV patients underwent resection. Chemotherapy and radiotherapy use increased by at least 10% per annum. There was a notable increase in pre-operative radiotherapy from 2000 onwards. Patient-related factors were significantly associated with treatment receipt. Patients who were male, older, not married, or smokers had significantly higher risks of death. Chemotherapy was significantly associated with lower mortality for stage III, but not stage II, colon cancer. For rectal cancer, pre-operative radiotherapy was associated with reduced mortality. Surgery and chemotherapy were associated with longer survival for stage IV patients. The observed inequities in treatment and outcomes suggest that there is potential for further dissemination of therapies in routine practice. Improving treatment availability overall, and equity, has the potential to reduce mortality.

Abstract
BACKGROUND The time schedule for chemotherapy and primary tumor resection in patients with rectal carcinoma (RC) and unresectable synchronous metastases (USM) is not well defined. We evaluated whether response to chemotherapy is an appropriate criterion for deciding to perform surgery. METHODS We treated 22 patients with RC and USM who received chemotherapy and were regularly evaluated. After documentation of a partial remission (PR) or stable disease (SD), patients were offered resection of the primary tumor. Results were compared with those of a historical control group of 42 patients who underwent immediate surgery. RESULTS Seven patients had a PR, four showed SD, and 11 progressed under chemotherapy. Seven patients underwent resection of the primary tumor (no perioperative mortality). The median survival for all 22 patients was 20.2 months. Patients with primary tumor resection survived 27.2 months, whereas patients without resection survived only 12.4 months (p = 0.017). The median survival in the control group was 13.5 months (perioperative mortality, 9.5%). CONCLUSION Chemotherapy and response-dependent resection of the primary tumor results in the same survival time as that attained with immediate surgery. Patients who face a poor prognosis due to progressive disease are thereby spared the risks of major rectal surgery.

Abstract
BACKGROUND Despite being a common problem, the optimal management of in situ primary colorectal carcinomas in patients presenting with unresectable synchronous metastases remains unknown. To date, no prospective randomized studies have been conducted to evaluate the outcomes of different approaches to management. We studied the attitudes of clinicians involved in the management of this group of patients with a view to determine their treatment preferences and assess the feasibility of conducting a randomized study addressing the role of resection of primary colorectal carcinomas in patients presenting with unresectable synchronous metastases. METHODS A survey of Australian colorectal surgeons, Australian medical oncologists and Victorian rural general surgeons was conducted. RESULTS The results indicated that with regard to preferred treatment (i) for patients with asymptomatic sigmoid or caecal primary tumours, surgeons preferred surgery followed by chemotherapy, whereas oncologists preferred chemotherapy alone; (ii) for patients with symptomatic sigmoid or caecal primary tumours, both surgeons and oncologists preferred surgery followed by chemotherapy; and (iii) for patients with metastatic rectal carcinoma, whether asymptomatic or symptomatic, both surgeons and oncologists preferred a multimodality approach to treatment. Clinicians were accepting a broad range of treatment options for patients with both asymptomatic and symptomatic primary colorectal tumours. CONCLUSION There is a high level of acceptability among Australian clinicians for both surgical and non-surgical approaches to management of the in situ primary colorectal tumour in patients with unresectable synchronous metastases. Further research is warranted to determine the management strategy that will yield the best outcome for these patients.

Survival and symptomatic benefit from palliative primary tumor resection in patients with metastatic colorectal cancer: a review. Int J Colorectal Dis 2008; 23:559-68.

Abstract
BACKGROUND AND AIMS Patients with metastatic colorectal cancer have a limited life expectancy and are at risk for life-threatening tumor-related obstruction, perforation, and hemorrhage. Though surgical resection is performed frequently in this setting, its true benefit is not well-established. MATERIALS AND METHODS We reviewed the medical literature from 1996-2006 using the search terms metastatic colorectal cancer and primary resection to find studies that evaluated the management of primary tumors in metastatic colorectal cancer. All search results were included in our analysis and were assessed on the basis of methodologic quality. RESULTS/FINDINGS Twelve relevant studies were identified; ten were single-institution retrospective reviews and two were population-based studies using National Cancer Institute's Surveillance, Epidemiology, and End-Results database. No prospective or randomized studies were identified. Approximately 70% of patients diagnosed with metastatic colorectal cancer in the USA undergo primary tumor resection; only a minority have this done for tumor-related symptoms or as part of potentially curative resection. The postoperative mortality ranged from 9.0-11.2% in large cancer registries but was often lower in major cancer centers. Resection of asymptomatic primary tumors was frequently associated with prolonged survival but was not found to reduce significantly the incidence of life-threatening tumor-related complications. INTERPRETATION/CONCLUSION Retrospective data suggest that non-curative resection of asymptomatic colorectal primary tumors may prolong survival; however, selection bias and unaccounted clinical factors may explain this observation. Prospective, randomized surgical trials are needed to test the role of primary tumor resection in this setting, especially because of its current widespread use, and its associated cost, morbidity, and high postoperative mortality.

Abstract
OBJECTIVE Whether resection of the primary tumour is of benefit to patients with incurable rectal cancer (RC) remains a matter of debate. In this study we analyse prospectively recorded data from a national cohort. METHOD Among 4831 patients diagnosed with RC between 1997 and 2001, 838 (17%) patients were treated with palliative surgery. Patients were stratified according to disease stage, age and type of surgery. RESULTS A significantly longer median survival, 12 (range 10-13) months, was observed in patients treated with resection of the primary tumour compared with 5 (range 4-6) months in patients treated with nonresective procedures (P < 0.001). Median survival in months was significantly (P < 0.001) related to age (13; < 60 years of age, 10; 60 to 69 years, 7; 70 to 79 years, 6; >/= 80 years of age). In patients over 80 years, survival was similar regardless of the treatment. Thirty-day mortality varied from 2.5% to 20%, according to age groups. CONCLUSION The longer survival observed in patients with resection of the primary tumour may partly be explained by patient selection. Elderly patients (>/= 80 years) had a similar survival, irrespective of resection of the primary tumour or not. Careful consideration of the individual patient, extent of disease and treatment-related factors are important in decision-taking for palliative treatment for patients with advanced RC.

Abstract
BACKGROUND AND AIMS Approximately 20% of patients with colorectal cancer are initially diagnosed with stage IV. The majority has non-curative metastases, and their chances of survival are pitiful. This study evaluated the prognostic factors of survival and the access to the effective treatment in accordance with patients. MATERIALS AND METHODS We retrospectively analyzed 503 patients for demographics, tumor characteristics, the treatment modality, and the survival outcome. Curative operation was performed in 127 patients and palliative operation in 376 patients. RESULTS For the curative operation group, the 5-year survival rate was 34.5%, and the prognostic factors of survival and recurrence were male gender (p = 0.003, 0.009), pathologic N stage (p < 0.001, p = 0.002), and perineural invasion (p = 0.003, p = 0.026), respectively. For the non-curative operation group, the 5-year survival rate was 0%, and the median survival duration was 16.5 months. The potential predictors of survival for the palliative operation group were carcinoembryonic antigen level (p = 0.013), differentiation of tumor (p = 0.011), resection of primary tumor (p < 0.001), and chemotherapy (p < 0.001). But for the 131 patients with asymptomatic incurable disease, only chemotherapy was related to survival (p < 0.001). CONCLUSIONS The potential predictors of survival for curative stage IV colorectal cancer were male gender, pathologic N stage, and perineural invasion. Resection of the primary tumor and chemotherapy showed benefit for the incurable patients. But for the asymptomatic incurable patients, only chemotherapy prolonged the survival.

Abstract
Patients with advanced incurable colorectal cancer (CRC) face a grim prognosis. The goal of palliative intervention is directed at alleviating disease-related symptoms and improving quality of life. The provision of optimal palliative care for these patients is a compound and demanding process. This dilemma becomes more challenging when patients with advanced metastatic colorectal disease present with an incurable and asymptomatic primary lesion. Treatment options are numerous and include a variety of surgical and nonsurgical interventions. Most data regarding the role of surgery in palliation of CRC are from retrospective, nonrandomized case series. Surgical resection may provide good palliation of symptoms and prevent future tumor-related complications. Metal stents are also able to provide good palliative relief of obstruction and should be used when appropriate. The best palliative care will often require a multidisciplinary approach that involves input from surgical and nonsurgical teams, where treatment plans will be made in accordance with the wishes of the patient and family with a goal of decreasing morbidity and a focus on quality of life.

Abstract
OBJECTIVE To assess the safety and efficacy of self-expanding metallic stents (SEMS) placement for the relief of malignant colorectal obstruction in comparison to surgical procedures through a systematic review of the literature. SUMMARY BACKGROUND DATA Conventional therapies for relieving colorectal obstructions caused by cancer have high rates of morbidity and mortality, particularly when performed under emergency conditions, and palliative procedures resulting in colostomy creation can be a burden for patients and caregivers. METHODS A systematic search strategy was used to retrieve relevant studies. Inclusion of papers was established through application of a predetermined protocol, independent assessment by 2 reviewers, and a final consensus decision. Eighty-eight articles, 15 of which were comparative, formed the evidence base for this review. RESULTS Little high-level evidence was available. However, the data suggested that SEMS placement was safe and effective in overcoming left-sided malignant colorectal obstructions, regardless of the indication for stent placement or the etiology of the obstruction. Additionally, SEMS placement had positive outcomes when compared with surgery, including overall shorter hospital stays, and a lower rate of serious adverse events. Postoperative mortality appeared comparable between the 2 interventions. Combining SEMS placement with elective surgery also appeared safer and more effective than emergency surgery, with higher rates of primary anastomosis, lower rates of colostomy, shorter hospital stays, and lower overall complication rates. CONCLUSIONS Stenting appears to be a safe and effective addition to the armamentarium of treatment options for colorectal obstructions. However, the small sample sizes of the included studies limited the validity of the findings of this review. The results of additional comparative studies currently being undertaken will add to the certainty of the conclusions that can be drawn.

Abstract
Patients with metastatic disease from colorectal cancer are now living twice as long as they were one decade ago. With this increasing life expectancy, we are beginning to see these patients strive for an acceptable and improved quality of life. Medical advances have led to unanswered questions regarding the role of surgery in metastatic colorectal cancer. Despite the increasing application of laparoscopy for primary treatment of colorectal cancer, the appropriate role for laparoscopy in patients with stage IV disease has yet to be defined. This review addresses this topic and suggests treatment algorithms for patients with metastatic colorectal cancer. While unresectable, metastatic colorectal cancer remains incurable at the current time, continued advances will inevitably challenge this presumption and it is crucial to outline the role of laparoscopy in this patient population.

Abstract
OBJECTIVE The management of stage IV colorectal cancer is controversial. Resection of the primary tumour to prevent obstruction, bleeding or perforation is the traditional approach, although survival benefit is undetermined. Management consisting of diverting ostomy, enteric bypass, laser recanalization or endoscopic stenting is an alternative to radical resection. The purpose of this study was to determine the role of resection of the primary tumour in patients with stage IV colorectal cancer, with specific attention paid to survival benefit and safety. METHOD This was a retrospective review of all stage IV colon and rectal cancer patients in our tumour registry between 1991 and 2002. Data collected included patient demographics, presenting symptoms, detail from the hospital course including diagnostic data and operative management, complications and survival time (days). Survival analysis was performed to assess the effect of primary tumour resection on long-term survival. RESULTS 109 patients were studied. Sixty-two (57%) patients (group I) underwent resection of the primary tumour, whereas 47 (43%) patients (group II) were managed without resection. Median survival times for groups I and II were 375 (IQR: 179-759) and 138 (IQR: 35-262) days respectively (P < 0.0001). After controlling for age, sex, tumour location and level of liver involvement as well as liver function, patients who underwent resection still survived longer (HR = 0.34, 95% CI: 0.21-0.55). CONCLUSION Palliative resection of the primary tumour plays an essential role in the management of stage IV colorectal cancer. Resection can offer increased survival and is indicated in certain patients with incurable disease. Limited metastatic tumour burden of the liver was associated with better survival in such patients.

BACKGROUND It is still a matter of debate as to whether resective surgery of the primary tumor may prolong the survival of patients affected by incurable colorectal cancer (CRC). The main goal of this retrospective study, carried out on patients not undergoing any therapy other than surgery, was to quantify the benefit of primary tumor removal in patients with differently presenting incurable CRC. METHODS One hundred and thirty consecutive patients were operated on for incurable CRC (83 undergoing resective and 47 non-resective procedures). With the purpose of comparing homogenous populations and of identifying patients who may benefit from primary tumor resection, the patients were classified according to classes of disease, based on the "metastatic pattern" and the "resectability of primary tumor." RESULTS In patients with "resectable" primary tumors, resective procedures are associated with longer median survival than after non-resective ones (9 months vs 3). Only patients with distant spread without neoplastic ascites/carcinosis benefit from primary tumor removal (median survival: 9 months vs 3). Morbidity and mortality of resective procedures is not significantly different from that of non-resective surgery, either in the population studied or in any of the groups considered. CONCLUSIONS Palliative resection of primary CRC should be pursued in patients with unresectable distant metastasis (without carcinomatosis), and, intraoperatively, whenever the primary tumor is technically resectable.

Abstract
Background Incomplete or complete obstructive ileus due to colorectal cancer is generally treated by emergency surgery that has higher morbidity and mortality than elective surgery. Case Presentation Here we describe an endoscopic technique by which a safe bowel decompression was performed instead of emergency surgery in two patients with complete tumorous obstruction of the colon. By means of a polypectomy snare, a soft wire, an ERCP catheter, a set of endoscopes with different diameters (baby endoscope, gastroscope) and of argon plasma coagulation the tumor mass was reduced and the tumor stenosis was passed. The patients recovered from symptoms of colon obstruction, no procedure-associated complications were observed. One patient had surgery of the sigmoid tumor one week later (UICC-stage III), the other patient (UICC-stage IV) received systemic chemotherapy starting one week after endoscopic decompression. Conclusion Complete tumorous obstruction of the colon may be managed by endoscopic tumor debulking avoiding high risk emergency surgery and allowing immediate medical treatment of the primary tumor and of metastases.

Abstract
PURPOSE At the time of diagnosis, approximately one third of patients with rectal cancer present with advanced disease. In this study we focus on a group of patients with primary advanced rectal cancer considered as not operable. We address various clinical aspects relevant for decision-making in a group of patients in need of palliative care. METHODS Between January 1997 and December 2001, 4831 consecutive patients with rectal cancer were prospectively registered in the Norwegian Rectal Cancer Registry. In this national population-based cohort, 386 patients (8 percent) without surgical interventions were identified. These patients comprise the study population. Clinical characteristics and survivals were addressed. RESULTS Patients not surgically treated were significantly older compared with other treatment groups (median age, 80 years; interquartile range, 72-86 vs. median age, 71 years; interquartile range, 62-79 years) (P<0.001). Median survival time was 4.5 (range, 3.5-5.4) months, regardless of age, gender, or hospital category. Patients who received radiotherapy had a significantly increased survival (P<0.001) compared with patients not treated with radiation, with a median survival time of 10.2 (range, 7.3-12.1) months vs. 2.8 (range, 2.1-3.6) months, respectively. Use of chemotherapy was not associated with improved survival. In multivariate analysis, only stage of disease and radiotherapy were independent predictors of better survival. CONCLUSION Higher age and comorbidity seem to influence choice of treatment in this subgroup of patients with advanced rectal cancer disease. In nonsurgically treated patients, radiotherapy was associated with an improved survival. Our prospective, population-based cohort study emphasizes the dismal prognosis of these patients, which also should challenge our efforts and clinical approaches in palliative care.

Abstract
Massive lymph node metastasis of the para-aortic region and supraclavicular lymph nodes, Virchow's lymph node metastasis due to colon cancer, is extremely rare. We herein report a case of such systemic lymph node metastasis that was successfully treated with a combination of irinotecan (CPT-11) and UFT, a combination drug of tegafur and uracil. The patient was a 57-year-old woman who had a tumor in the ascending colon, and massively swollen para-aortic and supraclavicular lymph node metastasis. She was treated with combination chemotherapy of CPT-11 and UFT. The main tumor was detected as a decompressed scar, and the supraclavicular and para-aortic lymph nodes had completely disappeared after the second cycle of treatment. A histopathological examination and immunohistochemistry with cytokeratin showed complete remission of adenocarcinoma in the tumor and para-aortic lymph nodes. She remains alive without recurrence 52 months after chemotherapy. Combination chemotherapy of CPT-11 and UFT may be of potential value in the treatment of advanced colorectal carcinoma, and both histopathological and immunohistochemical confirmation of a complete remission may indicate prolonged disease-free survival.
