Asymptomatic colorectal cancer with un-resectable liver metastases: immediate colorectal resection or up-front systemic chemotherapy? Ann Surg Oncol 2006; 14:766-70. [PMID: 17103261 DOI: 10.1245/s10434-006-9146-1] [Citation(s) in RCA: 104] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2006] [Revised: 05/28/2006] [Accepted: 06/14/2006] [Indexed: 12/14/2022]
Abstract
BACKGROUND About 20% of patients with colorectal cancer have synchronous un-resectable liver metastases. Resection of colorectal cancer in patients with moderate-severe symptoms is mandatory before starting chemotherapy. Surgical treatment of asymptomatic colorectal cancers is still a matter of discussion. METHODS From January 2000 to December 2004, we prospectively collected data on 35 consecutive patients who were treated straightaway by chemotherapy without primary tumor resection. All patients underwent FOLFOX6 as first-line chemotherapy. The aim of the study was to evaluate the rate of surgical complications related to un-resected colorectal tumor. RESULTS The mean interval between diagnosis and start of chemotherapy was 23.1 days (95% CI: 17.3-28.8). Fifteen of the 35 patients (42.9%) were down-staged to surgery; the mean interval between chemotherapy start and colon-rectum cancer resection was 6.5 months (95% CI: 5.5-7.5). None of them developed complications related to the primary tumor during chemotherapy. Of the other 20 patients who did not undergo any curative surgery, 16 received a second line chemotherapy and 10 a third line: six patients are alive and without intestinal symptoms (mean follow up 22.5 months, 95% CI: 11.2-33.9). Only one patient (2.8%) developed clinical signs of intestinal occlusion 5.6 months from the start of chemotherapy and required urgent colostomy. CONCLUSIONS The rate of complications related to the non-resected colorectal tumor is very low using oxaliplatin as first line chemotherapy. Non-operative management of asymptomatic colorectal cancers with un-resectable liver metastases is a safe approach.

Abstract
OBJECTIVE For patients with laparoscopic stage M1 gastric adenocarcinoma, no resection of the primary tumor, and systemic chemotherapy, this study investigated the incidence of subsequent palliative intervention and survival. SUMMARY BACKGROUND DATA Laparoscopy was performed for patients with computed tomography scan stage M0 disease and no significant obstruction or bleeding. METHODS A prospectively maintained database for 1993 to 2002 was used to identify 165 patients (median age, 63 years) with laparoscopic M1 disease in the peritoneum (P1, adjacent to stomach, 9%; P2, few distant sites, 35%; or P3, disseminated, 30%) or liver (10%) or both (16%). Functional performance status (FPS, Eastern Cooperative Oncology Group) was 0 to 1 (84%) or 2 (16%). RESULTS Subsequent intervention was performed on 50% of patients, at median interval of 4 months (range, 1-35 months) after laparoscopy. Intervention was performed on the stomach for obstruction (33%), bleeding (8%), or perforation (1%) or on a distant site for a metastasis-related complication (20%). More than one intervention (maximum, 4) was performed in 21%. Laparotomy was necessary in 12%; the remainder had endoscopic or radiologic procedures or radiation therapy only. There was one intervention-related death. Median survival was 10 months, with 1-year survival of 39%. On multivariate analysis, better FPS (0-1; odds ratio, 4; P=0.001) and limited peritoneal metastasis (P1 or P2; 2; P=0.01) were independently associated with improved survival. CONCLUSIONS The incidence of subsequent intervention was 50%, but few patients had laparotomy. Intervention-related mortality was minimal. The burden of metastatic disease and functional performance status were important prognostic factors.

Abstract
BACKGROUND There is no consensus as to the management of the primary rectal cancer in the presence of distant metastasis and data on the outcomes of radical resection in stage IV rectal cancer are limited. This study aims to evaluate the results of resection of rectal cancer in the patients with stage IV disease and to analyze the factors that might affect the survival of these patients. METHODS Of the 744 patients with radical resection of primary rectal and rectosigmoid cancer during the study period from August 1993 to July 2002, 70 had stage IV disease on the initial presentation. The demographics, the operative details, the tumor characteristics, the postoperative outcomes and survival of the patients were collected prospectively. Factors influencing the survival were analyzed with univariate and multivariate analysis. RESULTS Fifty-three men and 17 women with a median age of 66 years (range: 31-90 years) were included. The median level of the tumor from the anal verge was 10 cm (range 3-20 cm). The operations included abdominoperineal resection (n = 5), anterior resection (n = 53), and Hartmanns operation (n = 11). The operation mortality was 4.3%. The overall morbidity was 42.7% while the surgical morbidity and the reoperation rates were 15.7% and 5%, respectively. The local recurrence rate was 4.3% and the 2-year actuarial rate was 7.8%. All the patients who had local recurrences also had disseminated peritoneal metastasis. The median cancer-specific survival of the patients who survived the surgery was 15.2 months. Multivariate analysis showed that the presence of gross residual local disease, lymph node metastasis, liver involvement of over 50%, the absence of surgical management of liver metastasis and those without chemotherapy were independent factors associated with poor survival. CONCLUSIONS Postoperative mortality and morbidity were acceptable in patients with stage IV rectal cancer. The local disease can be controlled effectively with radical resection. However, in patients with extensive liver involvement and advanced local disease, resection is not worthwhile because of the poor survival. Surgical management of the metastasis and the administration of chemotherapy are associated with better survival. However, the optional treatment regimes are yet to be defined.

Abstract
BACKGROUND The objective of this study was to analyze prognostic factors for survival and to assess the applicability of Kohne's classification in patients treated with irinotecan- or oxaliplatin-based first-line chemotherapy. PATIENTS AND METHODS One hundred forty-two consecutive cases from a single center were retrospectively reviewed. Median patient age was 62 years. Sixty percent were men. Eastern Cooperative Oncology Group (ECOG) performance status (PS) was 0/1 in 88%. Primary tumor resection (PTR) was performed in 80.6% of patients who initially had stage IV disease. Chemotherapy consisted of fluoropyrimidines or raltitrexed plus irinotecan (50.5%), oxaliplatin (38.5%), or both (11%). Univariate and multivariate analyses for survival were performed using pretreatment patient characteristics. RESULTS Median follow-up was 33.9 months and median overall survival was 15.9 months. Significantly unfavorable prognostic factors were PTR not being performed, disease involvement of >1 organ, liver metastases, undifferentiated histology, EGOG PS>1, increased serum carcinoembryonic antigen and cancer antigen 19.9 levels, hypoalbuminemia, leucocytosis, and elevated alkaline phosphatase and lactate dehydrogenase (LDH) levels. Only ECOG PS, PTR, increased LDH level, no hypoalbuminemia, and number of organs involved retained prognostic value in the multivariate analysis. The incidence and median survival for Kohne's prognostic groups were as follows: good (54.2%; 20 months), intermediate (26.8%; 15.7 months), and poor (19%; 6.8 months). For patients with stage IV disease at presentation, PTR was associated with a significantly longer survival, mainly in patients with an ECOG PS of 0/1. CONCLUSION Eastern Cooperative Oncology Group PS, PTR, serum albumin, increased LDH levels, and organ involvement were the main prognostic indicators in our series. Kohne's prognostic groups, developed in the era of 5-fluorouracil treatment, also seem to be applicable to patients treated with combination chemotherapy. Primary tumor resection should always be considered, especially in patients with an ECOG PS of 0/1. However, the benefit of PTR and multiple-agent chemotherapy is questionable in patients with an ECOG PS of >1.

Abstract
BACKGROUND The aim of this case-matched study was to determine the best treatment strategy for patients with asymptomatic colorectal cancer and irresectable synchronous liver metastases. METHODS Between 1997 and 2002, 27 patients with asymptomatic colorectal cancer and irresectable synchronous liver metastases were treated by chemotherapy without initial primary resection (chemotherapy group). These 27 patients were compared with 32 patients matched for age, sex, performance status, primary tumour location, number of liver metastases, nature of irresectable disease and type of chemotherapy, but who were treated initially by resection of primary tumour (resection group). RESULTS The 2-year actuarial survival rate was 41 per cent in the chemotherapy group and 44 per cent in the resection group (P = 0.753). In the latter group, the mortality and morbidity rates for primary resection were 0 and 19 per cent (six of 32 patients) respectively. In the chemotherapy group, intestinal obstruction related to the primary tumour occurred in four of 27 patients. The mean overall hospital stay was 11 days in the chemotherapy group and 22 days in the resection group (P = 0.003). CONCLUSION Systemic chemotherapy without resection of the bowel cancer is the option of choice because, for most patients, it is associated with a shorter hospital stay and avoids surgery without a detrimental effect on survival.

Abstract
BACKGROUND Surgical resection of the primary tumor for patients who present with incurable stage IV colorectal cancer is controversial. National practice patterns have not been described. We evaluated the use of primary tumor resection in patients presenting with stage IV colorectal cancer. METHODS Patients with stage IV colorectal cancer diagnosed between 1988 and 2000 were selected from the Surveillance, Epidemiology, and End Results database. Patients undergoing primary tumor resection were analyzed on the basis of sex, race, year of diagnosis, and the anatomical site of the primary tumor. We compared the survival of resected and nonresected patients. RESULTS A total of 17,658 (66%) of the 26,754 patients presenting with stage IV colorectal cancer underwent primary tumor resection. Patients with resected disease were more likely to be young (mean age of 67.1 vs. 70.3 years) and to have right-sided tumors (75.3%, 73.0%, and 45.6%, respectively, for right, left, and rectal; P < .001). In all age groups, patients undergoing resection had higher median and 1-year survival rates (colon: 11 vs. 2 months, 45% vs. 12%, P < .001; rectum: 16 vs. 6 months, 59% vs. 25%, P < .001) when compared with patients who did not undergo resection. CONCLUSIONS Most patients who present with stage IV colorectal cancer undergo resection of the primary tumor. The proportion of patients undergoing resection depends on patient age and race and the anatomical location of the primary tumor. The degree to which case selection explains the treatment and survival differences observed is not known. Further investigation of the role of surgery in the management of incurable stage IV colorectal cancer is warranted.

Abstract
BACKGROUND The prognostic impact of primary tumor resection in patients presenting with unresectable synchronous metastases from colorectal carcinoma (CRC) is not well established. In the present study, we analyzed fifteen factors to define the value of primary tumor resection with regard to prognosis. PATIENTS AND METHODS We identified 186 consecutive patients with proven stage IV CRC from the year 1995 to 2001. Variables were tested for their relationship to survival in univariate analyses with the Kaplan-Meier method and the log rank test. Factors that showed a significant impact were included in a Cox proportional hazards model. The tests were repeated for 107 patients who had no symptoms from their primary tumor. RESULTS Overall there were six independent variables with a relationship to survival: performance status, ASA-class, CEA level, metastatic load, extent of primary tumor, and chemotherapy. In the asymptomatic patients we investigated 13 factors, 3 of which proved to be independent predictors of survival: performance status, CEA level, and chemotherapy. Resection of primary tumor was only predictive of survival if in-hospital mortality was excluded. CONCLUSION Resection of the tumor, if possible, is doubtless the best option for stage IV CRC patients with severe symptoms caused by their primary tumor. In asymptomatic patients, chemotherapy is preferable to surgery.

Abstract
BACKGROUND Surgical management of patients with metastatic or recurrent rectal cancer remains controversial. Self-expanding metal stents are increasingly used for palliative treatment of advanced tumors, although long-term results are not yet available. METHODS Between 1996 and 2003, 521 patients underwent surgery for rectal neoplasms. In the same time period, self-expanding metal stents were used for palliation of 34 patients with malignant rectal obstruction and incurable disease. The outcome of the patients was analyzed retrospectively. RESULTS Rectal stents were successfully placed in 33 of 34 patients (97%) without major complications. Early failure occurred in 7 patients (21%) because of stent migration, pain, or incontinence. Long-term success with a mean patency of 5.3 months was observed in 26 patients (79%), but restenting was required in 2 patients. Despite the initial success of stenting, a colostomy was created in 2 other patients after 3.4 months and 9.2 months because of incontinence and rectovesical fistula. Overall, 6 of 33 patients (18%) underwent palliative surgery because of early complications (n = 4) or long-term failure of stent treatment (n = 2). CONCLUSIONS Self-expanding metal stents are useful to avoid a colostomy in selected patients with incurable rectal cancer and limited life expectancy. Nonetheless, a considerable number (18%) of patients will require surgical palliation because of failure of stent treatment.

Abstract
OBJECTIVES In asymptomatic patients presenting with non-resectable synchronous metastatic disease from colorectal adenocarcinoma, the beneficial effect of resecting the primary tumor remains to be documented. The aim of this study was to compare survival of patients with metastatic colorectal cancer who underwent elective resection of the primary tumor to those who did not. METHODS A retrospective analysis of patients with metastatic colo-rectal cancer treated between June, 1996 and December, 1999 was performed. Overall survival was compared between patients who underwent first-line resection of the primary colorectal tumor (group 1) or those who did not undergo elective resection of the primary (group 2). The probability of surgical resection of the primary tumor for gastrointestinal complications in group 2 was evaluated. RESULTS Thirty-one and 23 patients were included in groups 1 and 2 respectively. Five patients (21.7%, 95% confidence interval CI95% 4.9-38.5%) in group 2 required surgical treatment for intestinal obstruction due to the primary tumor. Two clinical characteristics were significantly different between groups 1 and 2: rectal localization (9.7% versus 34.7%; P=0.03) and presence of fewer than three metastases (29.0% versus 4.3%; P=0.03). Survival curves were not significantly different (logrank). Median duration of survival was 21 and 14 Months, respectively (P=0.718). CONCLUSION In patients with non-resectable synchronous metastatic disease, non-surgical management of the primary tumor is a rational alternative if asymptomatic. A prospective randomized trial integrating the quality-of-life factor should be organized.

Abstract
Abstract
The monoclonal antibody C225 directed against the epidermal growth factor receptor (EGFR) blocks downstream mitogenic signaling and is effective in patients with advanced colorectal cancer. Clinical data, however, suggest the presence of primary and secondary resistance mechanisms that are hardly understood. To define proteins involved in EGFR-triggered growth regulation and potential resistance mechanisms, we characterized the proteome profile of two colorectal cancer cell lines with a high expression of functional EGFR but a different response to treatment with C225. In Caco-2 and HRT-18, a complete saturation of EGFR was achieved after incubation with C225; whereas Caco-2 showed inhibition of proliferation, growth of HRT-18 was not suppressed. Using two-dimensional electrophoresis and subsequent mass spectrometry, we identified 14 proteins differentially expressed in both cell lines. All proteins are involved in metabolic pathways and malignant growth. Expression of enzymes such as ubiquitin carboxyl-terminal hydrolase isozyme 1, glutathione S-transferase P, and chloride intracellular channel protein 1 does not seem to interfere with the antiproliferative effect of anti-EGFR antibody. On the other hand, expression of proteins such as fatty acid binding protein and heat shock protein 27 might constitute strong antiapoptotic effects contributing to the nonresponse of HRT-18 to C225 treatment. Proteome-based investigations can help us better understand the complex protein interactions involved in EGFR signaling and its blockage by therapeutic monoclonal antibodies.

Abstract
About 20 per cent of patients with carcinoma of the colon or rectum present with metastatic disease. Surgeons are frequently asked to consider resection or other operative procedures in these patients for palliation. We performed this review to determine whether patients presenting with known metastatic colorectal cancer derive benefit from surgical intervention. We performed a retrospective review of all patients with Ml carcinoma of the colon or rectum who were identified from the University of Mississippi Medical Center Cancer Registry from April 1985 through February 2003. Patients who underwent hepatic and/or pulmonary resection with curative intent were excluded from analysis, as were patients with metachronous metastases. Eighty patients with Ml colorectal cancer who did not undergo surgery with curative intent were identified, and in 74 of these, complete medical records and follow-up were available. Forty-nine of the 74 patients (66%) underwent an operation, and 25 were managed nonoperatively. Indications for surgery included bowel obstruction, active hemorrhage, severe anemia from gastrointestinal bleeding with requirement for blood transfusions, intractable pain, and perforation of the colon. Average survival was 11.2 months for operative patients versus 6.5 months for nonoperative patients ( P < 0.05). Thirty-six patients who underwent resectional procedures had a postoperative hospitalization of 7.5 days and a median survival of 11.5 months. Thirteen patients who had a nonresectional procedure had an average postoperative stay of 9 days and a median survival of 4 months. Median survival in those who did not undergo an operation was 4.8 months. Although metastatic colorectal carcinoma cannot usually be cured by surgical intervention, many patients who present with metastatic disease will benefit from palliative operations with relatively short hospitalizations and reasonable survival. Those who are not candidates for resection of the primary tumor have shorter survival times. Surgery can alleviate many of the distressing symptoms in patients with metastatic colorectal carcinoma.

Abstract
PURPOSE The prognosis for metastatic colorectal cancer is grave. Whether to perform surgical resection or palliative treatment remains controversial for this advanced disease. In this retrospective study, we collected data from patients with Stage IV colorectal cancer to identify prognostic factors for predicting selection criteria for surgical treatment in patients with metastatic disease. METHODS A retrospective chart review was performed for patients treated from 1992 to 1999 from the Koo Foundation Sun Yat-Sen Cancer Center Tumor Registry. Seventy-four patients were identified as having Stage IV disease at the time of diagnosis. Data concerning the patients' demographics, laboratory results, operative procedure, mortality, morbidity, and survival were collected. Independent variables and survival time were analyzed by the independent t-test method. The difference was considered statistically significant at P < 0.05. RESULTS Overall survival time for the patients with Stage IV colorectal cancer was 16.1 months. Survival in the curative resection group was significantly longer than that in the noncurative group (31.9 vs. 12.7; P < 0.016). The operative mortality and morbidity rates were 5.6 percent (4 of 71) and 21.1 percent (15 of 71), respectively. The two most common complications were leakage at the site of anastomosis and urinary tract infection. Based on these results, we conclude that patients older than 65 years, with metastases at multiple sites, intestinal obstruction, preoperative carcinoembryonic antigen level > or =500 ng/ml, lactate dehydrogenase > or =350 units/liter, hemoglobin <10 mg/dl, or hepatic parenchymal replacement by tumor >25 percent have poor prognosis for surgical intervention. CONCLUSION Whether to perform primary tumor resection in patients with asymptomatic Stage IV colorectal cancer remains controversial; however, the more aggressively we perform radical resection and metastasectomy to selected patients, the more survival benefits the patients obtain.

Abstract
BACKGROUND Surgical resection of primary colorectal cancer (CRC) in patients with stage IV disease at initial presentation remains controversial. Although bowel resection to manage symptoms such as bleeding, perforation, or obstruction has been advocated, management of asymptomatic patients has not been well defined. Patient-dependent factors (performance status, comorbid disease) and extent of distant metastases are among the considerations that impact on the decision to proceed with surgical management in asymptomatic stage IV CRC patients. We postulated that selected patients might benefit from elective resection of the asymptomatic primary CRC. The extent of distant metastases was objectively measured by several methods to identify potential prognostic variables that may help guide patient selection in this population. STUDY DESIGN We reviewed hospital and colorectal service databases for the years 1996 to 1999. Stage IV patients who had colorectal resections with gross residual metastatic disease were identified (n = 209). Among these 209 patients, 82 patients operated on for symptoms (obstruction, perforation, bleeding, or pain) were excluded, leaving 127 patients who underwent elective resection of their asymptomatic primary CRC. Over the same time period, 103 stage IV patients who did not undergo resection were identified. Data on patient characteristics and clinical management were collected. A radiologist performed an independent review of available CT scans to assess extent of liver disease. The chi-square test was used for analysis of categoric data and Student's t-test for continuous variables. Survival was determined by the Kaplan-Meier method and distributions compared by the log rank test. Multivariate analysis was performed using Cox regression. RESULTS The resected group could be easily distinguished from the nonresected group by a higher frequency of right colon cancers (p = 0.03) and metastatic disease restricted to the liver (p = 0.02) or one other site apart from the primary tumor (p = 0.02). Resected patients had prolonged median (16 versus 9 months, p < 0.001) and 2-year (25% versus 6%, p < 0.001) survival compared with patients never resected. Univariate analysis identified three significant prognostic variables (number of distant sites involved, metastases to liver only, and volume of hepatic replacement by tumor) in the resected group. Volume of hepatic replacement was also a significant predictor of survival in Cox multivariate regression analysis (p = 0.01). Subsequent to resection of asymptomatic primary CRC, 26 patients (20%) developed postoperative complications. Median hospital stay was 6 days. Two patients (1.6%) died within 30 days of surgery. CONCLUSION Stage IV patients selected for elective palliative resection of asymptomatic primary colorectal cancers had substantial postoperative survival that was significantly better than those never having resection. Limited metastatic tumor burden and less extensive liver involvement were associated with better survival and a higher likelihood of benefit from elective bowel resection in asymptomatic patients with incurable stage IV CRC.
