Abstract
Purpose Perforation and obstruction in colorectal cancer are poor prognostic factors. We aimed to evaluate the oncological outcomes of patients with colon cancer presenting with perforation or obstruction. Methods A total of 260 patients underwent surgery for colon cancer between January 2015 and December 2017. Among them, 54 patients who underwent emergency surgery for perforated (n = 32) or obstructive (n = 22) colon cancer were included. Results The perforation (PG, n = 32) and obstruction groups (OG, n = 22) did not differ significantly in age (p = 0.486), sex (p = 0.821), tumor stage (p = 0.221), tumor location (p = 0.895), histologic grade (p = 0.173), or 3-year overall survival rate (55.6% vs. 50.0%, p = 0.784). However, the PG had a higher postoperative complication rate (44% vs. 17%, p = 0.025), longer intensive care unit stay (4.8 days vs. 0.8 days, p = 0.047), and lower 3-year recurrence-free survival (42.4% vs. 78.8%, p = 0.025) than the OG. In the multivariate analysis, perforation was significantly increased risk of recurrence (hazard ratio = 3.67, 95% confidence interval: 1.049–12.839, p = 0.042). Conclusion Patients with colon cancer initially presenting with perforation had poorer recurrence-free survival, higher postoperative complication rates, and longer ICU stays than those who had obstruction.

Abstract
Grading of tumors located in the tubular digestive tract is an integral component of pathology assessment reports but is subordinate to the histological typing of tumors with respect to the prognostic significance. Tumor grading has not been shown to be an independent prognostic marker for most tumor entities in the gastrointestinal tract; however, it may be relevant for further routine treatment decision making in early Union Internationale Contre le Cancer (UICC) stage cancers in which the prognosis for patients is less dominated by advanced tumor spread. Owing to the more favorable prognosis of microsatellite instability in colorectal cancer, the World Health Organization (WHO) has recommended that poorly differentiated tumors should be tested and graded as low grade (G1/G2) when microsatellite instability is detected. This recommendation has been integrated into the German S3 guidelines for colorectal cancers. Accordingly, microsatellite instability testing for grading purposes should become routine practice.

Abstract
Twenty percent of colon cancers present as an emergency. However, the association between emergency presentation and disease-free survival (DFS) remains uncertain. Consecutive patients who underwent elective (CC) and emergent (eCC) resection for colon cancer were included in the analysis. Survival outcomes were compared between the 2 groups in univariate/multivariate analyses. A total of 439 patients underwent colonic resection for colon cancer during the interval 2000-2010; 97 (22.1%) presented as an emergency. eCC tumors were more often located at the splenic flexure (P = 0.017) and descending colon (P = 0.004). The eCC group displayed features of more advanced disease with a higher proportion of T4 (P = 0.009), N2 tumors (P < 0.01) and lymphovascular invasion (P< 0.01). eCC was associated with adverse locoregional recurrence (P = 0.02) and adverse DFS (P < 0.01 ) on univariate analysis. eCC remained an independent predictor of adverse locoregional recurrence (HR 1.86, 95% CI 1.50-3.30, P = 0.03) and DFS (HR 1.30, 95% CI 0.88-1.92, P = 0.05) on multivariate analysis. eCC was not associated with adverse overall survival and systemic recurrence. eCC is an independent predictor of adverse locoregional recurrence and DFS.

Abstract
BACKGROUND Although a great deal of progress has been made in the management of colorectal cancer in terms of neoadjuvant modalities, surgical techniques and adjuvant therapies, the recurrence of tumors remains an enigmatic complication in patients. A better understanding of colorectal cancer and of factors that lead to recurrence of disease can provide helpful information for designing more effective screening and surveillance methods. AIM To investigate the factors that may lead to local recurrence of colorectal cancers. MATERIALS AND METHODS The current retrospective case study evaluated 617 patients admitted to the Iranian Cancer Institute (the largest referral cancer center in the country) from 1995 to 2009 with confirmed colorectal cancer. Patients with distant metastasis, or with pathology other than adenocarcinoma and no follow-up, were excluded (175 patients). The remainder (442) included 294 (66.5%) with rectal cancer and 148 (33.5%) with colon cancer. The median duration of follow-up was 26 months. RESULTS The total rate of recurrence was 17.4%, comprising 19.6% and 16.3% recurrence rates in colon and rectal cancer, respectively. CONCLUSIONS Recurrence of colorectal cancer was significantly correlated to tumor grade (p<0.008).

Abstract
Locoregional tumor recurrence after curative therapy for colorectal cancer is therapeutically challenging and associated with poor prognosis. Goal of this single-center study was to analyze patients with locoregional recurrence with regard to therapeutic strategies and outcome for colon and rectal cancer each. Charts of all patients surgically treated for colorectal cancer in the period from 2000 to 2011 (n = 1296) were examined; patients with locoregional recurrence (n = 86) were then further analyzed. Fifty-three (10.2%) patients with rectal and 33 (5.6%) patients with colon cancer developed a locoregional recurrence, median 24.5 months after first diagnosis. Recurrence-specific therapy was applied in the majority of the patients (84.8% colon, 90.7% rectum); a surgical approach was undertaken in 82.1% (colon) and in 56.3% (rectum). Five-year overall survival after locoregional recurrence was 13% for rectal cancer and 9% for colon cancer. Itemized analysis for the approached therapeutic regimens revealed that radical recurrence resection (R0) significantly prolongs overall survival (p = 0.003) in rectal cancer, as does a surgical approach itself, as compared to conservative treatment modalities. If feasible, oncologic radical resection of the relapse (R0) significantly influences patient outcome and overall survival in rectal cancer.

Abstract
AIM To report data supporting the development of tailored treatment strategies for rectal cancer. METHOD A comprehensive review of the literature on the impact of prognostic factors cur-rently not included in international guidelines in rectal cancer management. RESULTS There is considerable variation in treatment guidelines for rectal cancer worldwide, especially for Stage II and Stage III disease. Long-term side effects of chemoradiotherapy are not considered in any guideline. Detailed knowledge, and the prognostic impact, of the circumferential resection margin, tumour grade and venous invasion should be factored into the development of a treatment strategy. CONCLUSION Factors additional to the TNM system should improve decision making for contemporary rectal cancer treatment. Optimized radiological and pathological evaluations, and a focus on detailed clinical factors, should be the basis for treatment decisions. International guidelines should consider all known prognostic factors for long-term oncological and functional outcomes.

Abstract
BACKGROUND AND AIMS Gender differences in the prognosis of colorectal cancer (CRC) remain controversial. The aim of this study was to complete a comprehensive analysis of gender differences in CRC survival derived from population registries in Taiwan. MATERIALS AND METHODS We analyzed survival data for patients diagnosed with CRC between 1998 and 2005 derived from the Taiwan Cancer Registry database. During this time period, 65,113 patients were registered, and 62,060 patients were eligible. Gender differences in overall survival and cancer-specific survival were analyzed by use of the Kaplan-Meier method. We then modeled the risk in different genders by use of a multivariate proportional hazard (Cox) model adjusting for possible confounders of survival. RESULTS The 5-year period overall and cancer-specific survivals were significantly higher in women than in men [51.84% (95% confidence interval (CI), 51.22-52.46) vs. 47.68% (95% CI, 47.14-48.22), log-rank p < 0.001; and 56.44% (95% CI, 55.82-57.07) vs. 53.47 % (95 % CI, 52.92-54.01), log-rank p < 0.001, respectively]. Subgroup analysis revealed higher overall and cancer-specific survivals in women between 50 and 80 years age and those with adenocarcinomas (p < 0.001). By use of Cox modeling, we noted a decreased hazard ratio (HR) for death from CRC in women compared with men (HR, 0.820-0.971), especially in the 50-80-year age group. All estimated HRs, after adjusting for age, tumor histology, and tumor site, had significant trends of a decreasing risk of death from CRC in women. CONCLUSIONS Our findings suggest that overall and cancer-specific survival advantage was most evident in women between 50 and 80 years of age.

Abstract
Purpose Lymph-node metastasis is the most important predictor of survival in stage III rectal cancer. The number of metastatic lymph nodes may vary depending on the level of specimen dissection and the total number of lymph nodes harvested. The aim of this study was to evaluate whether the lymph node ratio (LNR) is a prognostic parameter for patients with rectal cancer. Methods A retrospective review of a database of rectal cancer patients was performed to determine the effect of the LNR on the disease-free survival (DFS) and the overall survival. Of the total 228 patients with rectal cancer, 55 patients with stage III cancer were eligible for analysis. Survival curves were estimated using the Kaplan-Meier method. Cox regression analyses, after adjustments for potential confounders, were used to evaluate the relationship between the LNR and survival. Results According to the cutoff point 0.15 (15%), the 2-year DFS was 95.2% among patients with a LNR < 0.15 compared with 67.6% for those with LNR ≥ 0.15 (P = 0.02). In stratified and multivariate analyses adjusted for age, gender, histology and tumor status, a higher LNR was independently associated with worse DFS. Conclusion This study showed the prognostic significance of ratio-based staging for rectal cancer and may help in developing better staging systems. LNR 0.15 (15%) was shown to be a cutoff point for determining survival and prognosis in rectal cancer cases.

Abstract
PURPOSE Recurrent disease following complete cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is a relevant clinical scenario. We aimed to determine risk factors for recurrence. METHODS Prospectively collected data of patients enrolled in the Peritoneal Surface Malignancy Program at the University of Tübingen between 2005 and 2011 were retrospectively analyzed. All patients were treated by standardized CRS and HIPEC. Recurrence was defined either radiographically by CT, PET-CT scan, or reoperation. RESULTS Fifty-two patients received complete CRS (CC-0/CC-1) and HIPEC. Median time to recurrence was 229 days (103-1,028). Overall recurrence rate within follow-up was 48 %. Of patients with recurrent disease, 44 % experienced extraperitoneal systemic tumor spread. In multivariate analysis, grading of ≥ 3 was shown as an independent risk factor for recurrent disease, while a trend was observed for maximal tumor load in the upper abdominal region. Clinical parameters did not show an impact on recurrence. CONCLUSIONS Primary tumor grading seems to be an independent risk factor for recurrence following complete CRS and HIPEC in colorectal cancer-derived peritoneal surface malignancies.

Abstract
INTRODUCTION Although current guidelines recommend distal resection margins (DRM) of 2-5 cm in rectal cancer operation, smaller margins may be safe. We therefore assessed the impact of distal margins on outcomes in patients with rectal cancer treated with neoadjuvant chemoradiotherapy (CRT) followed by radical resection or resection followed by adjuvant CRT. MATERIALS AND METHODS This study involved 376 patients who underwent sphincter-saving resection for rectal adenocarcinoma and pre- or postoperative CRT between 2000 and 2006. DRMs were measured on pinned fixed specimens. We excluded patients who did not complete planned CRT and those with stage IV disease. A retrospective cross-sectional analysis was performed. RESULTS No significant differences in local recurrence (9.8 versus 7.3%; P = 0.324) and systemic recurrence (16.4 versus 18.7%; P = 0.731) were observed in patients with DRMs of ≤5 and >5 mm, respectively. Moreover, in each DRM category, there were no differences in local and systemic recurrence rates between patients who received pre- or postoperative CRT. DRM did not affect overall survival (P = 0.880) or 5-year survival rate (80.3 versus76.8%; P = 0.340). CONCLUSION A distal margin of at least 5 mm with negative resection margin on frozen section does not reduce oncological safety in rectal cancer patients who receive pre- or postoperative CRT.

Abstract
BACKGROUND AND OBJECTIVES To determine whether the patterns of failure are correlated with the degree of response to preoperative chemoradiotherapy (CRT) and to evaluate outcomes after recurrence in rectal cancer patients who underwent CRT followed by resection. METHODS Response to CRT was evaluated according to tumor regression grade (TRG), with 581 patients categorized into two groups, a good response (GR, TRG 3/4, n = 224) and a poor response (PR, TRG 1/2, n = 357) group. RESULTS At a mean follow-up of 61 months, the 5-year overall (88.2% vs. 71.3%, P < 0.001) and disease-free (86.7% vs. 63.6%, P < 0.001) survival rates were higher in the GR group. In patients with recurrence, time to recurrence was shorter (13.5 months vs. 18.7 months, P = 0.01), and the cumulative 2-year recurrence rates (92.9% vs. 73.4%, P = 0.024) was higher in the GR group. Rates of local (1.3% vs. 9.5% P < 0.001) and systemic (11.6% vs. 27.2%, P < 0.001) recurrence were significantly lower in the GR group, as were rates of pulmonary (3.6% vs. 15.1%, P < 0.001) and systemic lymph node (1.3% vs. 5.9%, P = 0.009) recurrences. The 5-year overall survival rates after recurrence were similar (GR: 23.7% vs. PR: 16.0%, P = 0.911). CONCLUSIONS More than one-third of patients with locally advanced rectal cancer showed good response to CRT, with improved local and systemic recurrence rates, especially low rates of pulmonary and systemic lymph node recurrence. Recurrence occurred earlier in the GR than the PR group, and oncologic outcomes after recurrence did not differ between the two groups.

Abstract
AIM To study any possible differences in morbidity, mortality and overall survival rate after curative surgery for obstructive colon cancer according to tumour location. METHOD From January 1994 to December 2006, patients with colonic cancer presenting as obstruction were analysed. The two groups were defined as proximal and distal according to the tumour location with respect to the splenic flexure. In relation to the surgeon specialization, patients were operated on by a colorectal surgeon and by a general surgeon. Postoperative morbidity and mortality and cancer-related survival at 3 years were analysed. RESULTS Of the 377 patients included in the study, there were 173 patients (45.9%) in the proximal group and 204 patients (54.1%) in the distal group. The global morbidity was 54.9% without differences in postoperative morbidity except for anastomotic leakage, which was higher in the proximal group (P < 0.014). No differences in postoperative mortality were observed. After patients were stratified by the tumour node metastasis system, the differences between the groups, with respect to 3-year overall survival, cancer-related survival and probability of being free from recurrence, did not reach statistical significance. The overall survival after radical surgery for colonic obstruction was 57.6%. CONCLUSION Mortality and morbidity after emergency surgery for obstructing colon cancer are high. Specialization in colorectal surgery influences postoperative results in terms of lower anastomotic dehiscence rate after emergency proximal colon resection. After radical surgery, tumour location does not appear to influence the prognosis of obstructive colon cancer.

The follow-up after radical surgery of colorectal cancer: is it time for a "tailored" strategy? Clin Colorectal Cancer 2011; 10:81-4.

Abstract
The problem of the surveillance for colorectal cancer after radical surgery is a widely debated argument. Like for other solid tumors, the issue is divided in 2 main routes: the early diagnosis of recurrence and the early diagnosis of a second primary cancer. Genetic and molecular features have been recognized as useful tools to measure these risks, however, the instruments are still insufficient to design a personalized strategy for the patient. In an era of "tailored therapies" in oncology, even the follow-up of the surgically treated patient for colorectal cancer should enter "a tailor's shop in which several competent tailors" should be available to manage a complex problem.

Abstract
BACKGROUND Obstruction (OBSTR) and perforation (PERF) in colorectal cancer impact adversely upon outcomes, and cancer-related survival may also be affected. However, data are sparse, particularly on disease-free survival (DFS) where the cancer is both obstructed and perforated (OBS-PERF). METHODS Data were extracted from a prospectively collected database of 1876 colorectal cancer patients managed and followed up at the Royal Brisbane Hospital from 1984 to 2004. The patients who had curative surgery (n = 1426) were classified as OBSTR (n = 153), PERF (n = 53), OBS-PERF (n = 19), and uncomplicated (UNCOM; n = 1201). Kaplan-Meier survival and Cox proportional hazard analyses were performed. RESULTS Postoperative mortality within 30 days of surgery was 1.5% (n = 22) and the overall complication rate was 40.8% (n = 582). However, only 7.2% (n = 102) required reoperations. The median survival time was 71 (IQR = 64.9-77.1) months and the median follow-up for DFS was 37.5 (IQR 14-68) months. The overall recurrence rate was 32.7% (n = 466), the local recurrence rate was 9.4% (n = 135), and local and distant recurrences occurred in the same patient in 4.7% (n = 67). Male gender, OBSTR, PERF, OBS-PERF, emergency operation, major medical and surgical complications, reoperation, TNM staging, tumor grading, and tumor venous invasion adversely affected DFS (p < 0.05). Multivariate analysis showed that OBS-PERF (p = 0.008), major medical complications (p = 0.011), reoperation (p = 0.018), TNM staging (p < 0.001), grading (p = 0.018), and venous invasion (p = 0.002) were independently associated with a poorer DFS. CONCLUSIONS OBS-PERF colorectal cancer is associated with a poorer DFS, which may be worse than either OBSTR or PERF alone.

Abstract
Recent evidence suggests that intensive follow-up after curative resection of colorectal cancer is associated with a small but significant improvement in survival. Regimens that employ cross-sectional imaging and carcinoembryonic antigen determination appear to have the greatest benefit. A risk-adapted approach to follow-up, intensively following patients at highest risk of recurrence, increases efficacy and cost-effectiveness. Ongoing improvements in risk stratification, disease detection, and treatment will increase the benefits of postoperative surveillance. Large randomized controlled trials are needed to determine the optimal surveillance regimen and must include an analysis of survival, quality of life, and cost-effectiveness to assess efficacy properly.

Abstract
We report a rare case of postoperative colon cancer recurrence who presented with hematuria 13 years after resection of the primary colonic cancer. The patient was 72 years of age and underwent surgical resection of sigmoid colon cancer at another regional hospital in 1994. Since June 2007, this patient has complained of hematuria and bloody stool. On physical examination, tenderness and a hard, indurated mass was palpable in the lower mid-abdomen. Abdominal computed tomography showed a metastatic tumor at the lower midline peritoneum with invasion of the adjacent abdominal wall. Her serum carcinoembryonic antigen level was elevated to 32 ng/dL. Histopathology revealed metastatic colonic adenocarcinoma in the jejunum and abdominal wall.

Abstract
BACKGROUND AND AIMS There are a range of rates and a number of prognostic factors associated with the local recurrence of colorectal cancer after curative resection. The aim of this study was to identify the potential prognostic factors of local recurrence in patients with colon and rectal cancers. MATERIALS AND METHODS A retrospective review of 1,838 patients who underwent curative resection of non-metastatic colorectal cancer was conducted. The patients were treated between 1994 and 2004, and had a minimum follow-up of 3 years. RESULTS There were 994 patients with colon cancer and 844 patients with rectal cancer. The median duration of follow-up was 60.9 +/- 24.5 months. With respect to colon cancer, the local recurrence rate was 6.1% (61 patients). With respect to rectal cancer, 95 patients had a local recurrence (11.3%), the rate of which was statistically greater than the local recurrence rate for colon cancer (p < 0.001). The overall recurrence rate was 16.4% (301 patients), and the local recurrence rate, with or without systemic metastases, was 8.5% (156 patients). Local recurrences occurred within 2 and 3 years in 59.9% and 82.4% of the patients, respectively. In patients with colon and rectal cancer, the pathologic T stage (p = 0.044 and p = 0.034, respectively), pathologic N stage (p = 0.001 and p < 0.001, respectively), and lymphovascular invasion (p = 0.013 and p = 0.004, respectively) were adverse risk factors for local recurrence. The level of the anastomosis from the anal verge was an additional prognostic factor (p = 0.007) in patients with rectal cancer. CONCLUSION Compulsive follow-up care of patients with colon and rectal cancers is needed for 3 years after curative resection, especially in patients who have adverse risk factors for local recurrence.

Abstract
PURPOSE This study examined the correlation between depth of local invasion in colon cancer and tumor spread and patient survival. METHODS A cohort of 796 patients with a complete set of TNM staging information following an elective resection for colon cancer was selected. The rates of lymph node and distant metastasis, tumor differentiation, and extramural venous invasion for different tumor (T) categories were compared. The effects of initial tumor (T) category on overall patient survival were studied. RESULTS The depth of local tumor invasion correlated strongly with nodal involvement (P = 0.0001), rates of extramural venous invasion (P = 0.0002), poor differentiation (P = 0.0001), and distant metastasis (P = 0.0001). Fifty-seven percent of the patients remained lymph node-negative and distant metastasis-negative irrespective of their depth of tumor invasion had no impact on overall survival (P = 0.49). For patients with lymph node or distant metastasis (43 percent), depth of tumor invasion had significant impact on overall survival (P = 0.001). Thirteen percent of T3N1, 33 percent of T3N2, 40 percent of T4N1, and 68.percent of T4N2 cases had distant metastasis at presentation. CONCLUSION Two types of colon cancer were observed: locally active and tendency to metastasize. For the latter, overall mortality and the risk of metastasis increased with depth of tumor invasion.

Abstract
PURPOSE This is a systematic review to evaluate the impact of various follow-up intensities and strategies on the outcome of patients after curative surgery for colorectal cancer. METHODS All randomized trials up to January 2007, comparing different follow-up intensities and strategies, were retrieved. Meta-analysis was performed by using the Forest plot review. RESULTS Eight randomized, clinical trials with 2,923 patients with colorectal cancer undergoing curative resection were reviewed. There was a significant reduction in overall mortality in patients having intensive follow-up (intensive vs. less intensive follow-up: 21.8 vs. 25.7 percent; P = 0.01). Regular surveillance with serum carcinoembryonic antigen (P = 0.0002) and colonoscopy (P = 0.04) demonstrated a significant impact on overall mortality. However, cancer-related mortality did not show any significant difference. There was no significant difference in all-site recurrence and in local or distant metastasis. Detection of isolated local and hepatic recurrences was similar. Intensive follow-up detected asymptomatic recurrence more frequently (18.9 vs. 6.3 percent; P < 0.00001) and 5.91 months earlier than less intensive follow-up protocol; these were demonstrated with all investigation strategies used. Intensive surveillance program detected recurrences that were significantly more amenable to surgical reresection (10.7 vs. 5.7 percent; P = 0.0002). The chance of curative reresection were significantly better with more intensive follow-up (24.3 vs. 9.9 percent; P = 0.0001), independent of the investigation strategies used. CONCLUSIONS Intensive follow-up after curative resection of colorectal cancer improved overall survival and reresection rate for recurrent disease. However, the cancer-related mortality was not improved and the survival benefit was not related to earlier detection and treatment of recurrent disease.

Abstract
Recurrence of the disease represents the major problem in patients who undergo "curative" resection for rectal cancer, with published rate ranging from 3 to 50%. Most relapses occur within first two years of follow-up. Depending on the site of the recurrence, it can be local or distant. It also can be solitary or diffuse. In terms of potential surgical cure the best results are achieved with solitary, localized metastases. The most common sites of the solitary metastases are pelvis, liver and lung, with a fairly even distribution among these three sites. Other sites of the localized metastases can be peritoneum, lymph nodes, brain, bone, abdominal wall, ureter and kidney. These sites are less common, but not so amenable to resection. Local recurrence varies depending on the original type of surgery. It can be stated that surgical technique directly influences local recurrence rate in patients with rectal cancer. According to the results from a number of different authors 5-year survival rate after reresection is 2-13% of all patients with locally recurrent cancer, both alone and associated with distant metastases. The most important moment in this problem is to decide when not to operate. The absolute contraindications for salvage surgery are: "frozen pelvis", aneuploid tumors and those with mucinous component, clinical or CT evidence of invasion of the pelvic nerves, lymphatics or veins, or ureter bilaterally. Also, evidence of involvement of the lateral pelvic sidewalls and/or upper sacral marrow, and/or S2 is an absolute contraindication for surgery. Thus, main goals of this type of surgery are respectively: palliation of symptoms, a good quality of life and, if possible, cure with low treatment-related complication rates.

Abstract
Neoadjuvant chemoradiation therapy (CRT) is the preferred treatment option for distal rectal cancer. Complete pathological response after CRT has led to the proposal of nonoperative approach as an alternative treatment for highly selected patients with complete clinical response. However, patterns of failure following this strategy remains undetermined. Three hundred sixty-one patients with distal rectal cancer were managed by neoadjuvant CRT including 5-FU, leucovorin, and 5040 cGy. Tumor response assessment was performed at 8 weeks following CRT. Patients with complete clinical response were not immediately operated on and were closely followed. One hundred twenty-two patients were considered to have complete clinical response after the first tumor response assessment. Of these, only 99 patients sustained complete clinical response for at least 12 months and were considered stage c0 (27.4%) and managed nonoperatively. Mean follow-up was 59.9 months. There were 13 (13.1%) recurrences: 5 (5%) endorectal, 7 (7.1%) systemic, and 1 (1%) combined recurrence. All 5 isolated endorectal recurrences were salvaged. Mean recurrence interval was 52 months for local failure and 29.5 months for systemic failure. There were five cancer-related deaths after systemic recurrences. Overall and disease-free 5-year survivals were 93% and 85%. Even though surgery remains the standard treatment for rectal cancer, nonoperative treatment after complete clinical response following neoadjuvant CRT may be safe and associated with good survival rates in a highly selected group of patients. Survival in these patients is significantly affected by systemic failure. Exclusive local failure occurs late after CRT completion and is frequently amenable to salvage therapy.

Abstract
A very low local recurrence rate of 3%-6% (associated with improved 5 year survival) is possible when proper oncological surgery is performed of mid and distal rectal adenocarcinoma. Restoration of bowel continuity is possible in most cases, without compromise of cancer clearance. Re-anastomosis can be performed with stapled, transabdominal hand-sewn or coloanal pull-through techniques. However after a direct (straight) anastomosis of the colon to the distal rectum/anus, up to 33% of patients have 3 or more bowel movements/d; some can be troubled with up to 14 stools a day. Construction of a 6-cm colonic J-pouch is likely to cause some reversed peristalsis which improves postoperative bowel frequency without causing neo-rectum evacuation problems. Colonic J-pouch-anal anastomosis patients have a median of 3 bowel movements a day compared with a median of 6 a day for straight anastomoses, at 1 year after surgery. In the longer term, bowel adaptation may enable the function after a straight anastomosis to approximate that of a colonic J-pouch-anal anastomosis. This probably depends in the former, upon whether the more rigid sigmoid colon or more distensible descending colon is used. An additional advantage of the colonic J-pouch-anal anastomosis is the lower risk of anastomotic complications. A more vascularized side-to-end (colonic J-pouch-anal) anastomosis is likely to heal better than an end-to-end (straight) anastomosis. Where the pelvis is too narrow for a bulky colonic J-pouch anal anastomosis, a coloplasty-anal-anastomosis is an option. The latter results in postoperative bowel function comparable with the colonic J-pouch. However, the risk of anastomotic complications is higher possibly related to its end-to-end anastomotic configuration. Laparoscopic techniques for accomplishing all the above are being proven to be effective. Restorative surgery for rectal cancer can be safely and effectively performed with methods to improve bowel function very acceptably; the future advances are likely in laparoscopy.

Abstract
OBJECTIVE The risk of a cancer recurrence has been correlated with the stage of the primary tumour at the time of presentation. However, once a recurrence has developed, the primary tumour stage may not be the determining prognostic factor anymore. The objective of this study was (i) to evaluate the association between the recurrence interval and the outcome of the recurrence, and (ii) to determine whether that interval was affected by the use of adjuvant radiation and/or chemotherapy. METHOD This retrospective study analysed 212 patients who developed recurrent colorectal cancer from 1987 to 1993. Primary parameters such as age, gender, primary tumour site and stage, and use of postoperative adjuvant treatment were correlated with the recurrence interval, the type and site of the recurrence (i.e. locoregional vs distant metastases), and the outcome. Uni- and multivariate analysis was used to compare the recurrence interval and survival between different subgroups as defined by risk factors. RESULTS The mean time between the primary and the recurrent tumour was 25 months (range 1-252 months) with 82% of the recurrences developing within 3 years after surgery. The recurrence interval was inversely correlated with the initial tumour stage. Poor survival was associated with a short recurrence interval (less than 12 months) and a distant recurrence site. Even after adjusting for the initial tumour stage, the use of adjuvant treatment did not prolong the interval, i.e. delay the onset of recurrent cancer. CONCLUSION The recurrence interval of colorectal cancer is a prognostic factor. However, the use of adjuvant therapy did not prolong that interval.

Abstract
Total mesorectal excision for low rectal cancers has been shown to reduce local recurrence rate after curative operation to <5 percent. The lack of anatomic appreciation of the mesorectum is an important cause of inter-surgeon variability in the outcome of rectal cancer surgery. Surgical illustrations depicting the mesorectal anatomy, however, are less than accurate. Basic surgical concepts must be illustrated correctly to be learned correctly. True-to-life illustration is the only way the learner can appreciate the actual situation and improve his/her surgical results. We describe the mesorectal anatomy with correlation to computerized tomography scans of the in vivo rectum to further illustrate the technique of total mesorectal excision in rectal cancer surgery.

Abstract
Quality assurance in colon cancer demands a multidisciplinary effort involving general practitioners, surgeons, radiologists, gastroenterologists, medical oncologists, and pathologists, among others. Maximal improvements in survival will result when colon cancer screening, diagnosis, staging, treatment and surveillance are optimized. We seek to identify those issues most relevant to the quality of care we provide our colon cancer patients.

Abstract
BACKGROUND Although a significantly decreased long-term survival has been observed in patients undergoing surgery for complicated colorectal tumors compared with uncomplicated ones, the role of radical oncologic surgery on emergency colonic cancer is not defined clearly. The aim of this study was to analyze the efficacy of a curative emergency surgery in terms of tumor recurrence and cancer-related survival compared with elective colonic surgery. METHODS Between January 1996 and December 1998, all patients with colonic cancer deemed to have undergone a curative resection were considered for inclusion in this prospective study. Patients were classified into 2 groups: group 1, after emergency surgery for complicated colonic cancer, and group 2, patients undergoing elective surgery. The main end points were cancer-related survival and the probability of being free from recurrence at 3 years. RESULTS Of the 266 patients included in the study, 59 patients (22.2%) were in group 1 and 207 patients (77.8%) were in group 2. Postoperative mortality was higher in group 1 (P=.0004). After patients were stratified by the tumor node metastasis system, differences between the groups with respect to overall survival of stage II tumors (P=.0728), the probability of being free from recurrence (P=.0827), and cancer-related survival (P=.1071) of stage III cancers did not reach statistical significance. Differences were observed for the overall survival in stage III tumors (P=.0007), and for the probability of being free from recurrence (P=.0011) and cancer-related survival (P=.0029) in stage II cancers. When patients with elective stage II tumors presenting 1 or more negative prognostic factor were compared with emergency patients affected by a stage II colonic cancer, no differences were observed. CONCLUSION Curative surgeries for complicated colonic cancer are acceptable in emergency conditions. Cancer-related survival and recurrence in patients with complicated colonic cancers may approach that of elective surgery if a surgical treatment with radical oncologic criteria is performed.

Abstract
Our aim was to review the results of total mesorectal excision (TME) in a specialised colorectal unit. Perioperative and follow-up data were prospectively collected in a computerised database. A review of all the records was made. The morbidity rate was about 14%, and was higher in patients with coloplasty due to a higher anastomotic leak rate. The local recurrence rate was 2%, the distant metastasis rate was 11%, and both local and distant metastasis occurred in 4%. About 95% of recurrence occurred within 3 years. There was better bowel function in patients with a colonic J-pouch in the first 2 years after surgery, but the advantage disappeared thereafter. There were no differences in function between descending and sigmoid colonic J-pouches. TME in a specialised colorectal unit has low morbidity and mortality. Our procedure of choice is that of a sigmoid colon J-pouch anal anastomosis.

Abstract
AIM To review the results of dynamic graciloplasty for total anorectal reconstruction after abdominoperineal resection (APR) for rectal cancer. PATIENTS AND METHODS Chart reviews were done on 17 patients who had dynamic graciloplasty following abdominoperineal resection and details of post-operative complications, bowel functions and recurrences were obtained. RESULTS Seventeen patients (12 males) had dynamic graciloplasty after APR for low rectal tumours. The median age was 58.5 years (range 33-78). Three patients from overseas were lost to follow-up, and three still have not had the defunctioning stoma closed. Only 11 patients were available for evaluation of function. The median time from graciloplasty to continence to solids and liquids is 15.7 months (range 0.4-21.9 months). Six patients had defecatory problems, requiring daily irrigation to evacuate. Nine patients were continent without need for gracilis stimulation. Only two patients needed gracilis stimulation to maintain continence. Fifty percent of rectal carcinoma patients had developed a recurrence. CONCLUSION Dynamic graciloplasty had a high morbidity and did not always bring about normal defecatory function. Gracilis stimulation was not needed to achieve continence in all cases. Conversely, dynamic graciloplasty may lead to defecatory difficulties in a large number of patients. Graciloplasty should only be considered three years after the initial APR to avoid performing the procedure in a patient who may develop recurrence as well as to select patients who are psychologically prepared for the surgery and its complications.

Abstract
OBJECTIVE Report overall long-term results of stage 0 rectal cancer following neoadjuvant chemoradiation and compare long-term results between operative and nonoperative treatment. METHODS Two-hundred sixty-five patients with distal rectal adenocarcinoma considered resectable were treated by neoadjuvant chemoradiation (CRT) with 5-FU, Leucovorin and 5040 cGy. Patients with incomplete clinical response were referred to radical surgical resection. Patients with incomplete clinical response treated by surgery resulting in stage p0 were compared to patients with complete clinical response treated by nonoperative treatment. Statistical analysis was performed using chi2, Student t test and Kaplan-Meier curves. RESULTS Overall and disease-free 10-year survival rates were 97.7% and 84%. In 71 patients (26.8%) complete clinical response was observed following CRT (Observation group). Twenty-two patients (8.3%) showed incomplete clinical response and pT0N0M0 resected specimens (Resection group). There were no differences between patient's demographics and tumor's characteristics between groups. In the Resection group, 9 definitive colostomies and 7 diverting temporary ileostomies were performed. Mean follow-up was 57.3 months in Observation Group and 48 months in Resection Group. There were 3 systemic recurrences in each group and 2 endorectal recurrences in Observation Group. Two patients in the Resection group died of the disease. Five-year overall and disease-free survival rates were 88% and 83%, respectively, in Resection Group and 100% and 92% in Observation Group. CONCLUSIONS Stage 0 rectal cancer disease is associated with excellent long-term results irrespective of treatment strategy. Surgical resection may not lead to improved outcome in this situation and may be associated with high rates of temporary or definitive stoma construction and unnecessary morbidity and mortality rates.

Abstract
AIM: This study was designed to compare the levels of v5 and v6 splice variants of CD44 evaluated using ELISA test in the serum of patients with colorectal cancer in different stages of progression of the disease estimated in pT stage according to WHO score, histopathological grade of malignancy and some clinicopathological features.
METHODS: The serum obtained from 114 persons with colorectal adenocarcinomas was examined using ELISA method. pT stage and grade of malignancy of the tumour were examined in formalin fixed and paraffin embedded materials obtained during operation.
RESULTS: Only the level of CD44 v5 in the serum of patients before operation with G2 pT4 tumour was lower than that in other probes and the difference was statistically significant. We did not find any other correlations between the level of v5 and v6 CD44 variants and other evaluated parameters.
CONCLUSION: The level of CD44 v5 and v6 estimated by ELISA test in the serum can not be used as a prognostic factor in colorectal cancer.

Abstract
BACKGROUND Previous studies have suggested that survival following surgery for colorectal cancer is better in women than men. However, the findings were inconsistent and few studies adjusted for case-mix. The aim of the present study was to establish whether there were gender differences in survival following surgery for colorectal cancer after adjusting for case-mix. METHODS Some 3200 patients who underwent resection for colorectal cancer between 1991 and 1994 in 11 hospitals in Scotland were included in the study. Five-year survival rates, and the corresponding hazard ratios, adjusted for age, mode of presentation, site of tumour, the nature of surgery and Dukes stage, were calculated for men and women. RESULTS Overall survival at 5 years was higher in women than men, in those with colonic tumours, those who underwent elective surgery and those who underwent apparently curative resection (all P < 0.001). Cancer-specific survival at 5 years was also higher in women (P = 0.008) and those who underwent elective surgery (P < 0.001). The adjusted hazard ratios, for women relative to men following curative resection, were 0.76 (95 per cent confidence interval (c.i.) 0.68 to 0.85) (P < 0.001) for overall survival and 0.84 (95 per cent c.i. 0.73 to 0.98) (P = 0.021) for cancer-specific survival. CONCLUSION Following apparently curative resection for colorectal cancer and after adjusting for case-mix, there was an excess of both cancer-related and intercurrent deaths in men.

Abstract
INTRODUCTION Current surveillance for recurrent intraluminal or metachronous colorectal cancer following resection is largely undertaken by colonoscopic examination of the remaining colon. The burden on colonoscopic services is high and the procedure is expensive. Immunological faecal occult blood testing (FOBT) is a sensitive and specific test for detecting colorectal cancer, and may fine tune the need for timely surveillance colonoscopy. METHODS Consecutive patients due for surveillance colonoscopy following colonic resection for cancer were prospectively studied. Each patient had a single faecal sample obtained at per rectal examination on a gloved examining finger. This was subjected to immunological FOBT in the clinic, and patients were categorized as FOBT positive or negative, according to the result. Colonoscopy as well as ultrasound or CT of the liver were performed within eight weeks of FOBT. RESULTS Six hundred and eleven patients had both FOBT and colonoscopy. Fifty-nine (13.6%) were categorized as FOBT-positive. Of these, nine had biopsy-proven recurrent or metachronous cancer, 12 patients had one, or more adenomatous polyps, one patient had radiation proctitis and two patients had pan-colonic mucositis following chemotherapy. In the remaining 552 FOBT-negative patients, no cancers were found. Thirty-eight patients had polyps that were removed. The sensitivity and specificity for detecting cancer by immunological FOBT was 100% sensitivity for detecting adenomatous polyps was 24% but specificity was 93%. CONCLUSION The immunological faecal occult blood test provides sensitive detection of metachronous and recurrent cancer in postoperative surveillance. Routine application may be used to reduce the frequency of colonoscopic surveillance, as a negative FOBT may be taken as a sign that colonoscopy may be deferred safely.

Abstract
BACKGROUND There is wide variability in reported locoregional recurrence rates after curative resection of adenocarcinoma of the intraperitoneal colon, and there is no universally accepted surgical technique regarding length of the resected specimen or extent of lymphadenectomy. The aim of this study was to determine the disease-free survival, locoregional failure, and perioperative morbidity of patients undergoing curative resection of colon adenocarcinoma. STUDY DESIGN The records of 316 consecutive patients undergoing curative resection for primary adenocarcinoma of the intraperitoneal colon between 1990 and 1995 were reviewed. Locoregional recurrence was defined as disease at the anastomosis or in the adjacent mesentery, peritoneum, retroperitoneum, or carcinomatosis. The product-limit method (Kaplan-Meier) was used to analyze survival and tumor recurrence. RESULTS The study population comprised 167 men and 149 women, mean age 70+/-12 years (range 22 to 95 years). Median followup was 63+/-25 months. Five-year disease-free survival was 84% overall. Disease-free survival paralleled tumor stage: stage I, 99% (n = 73); stage II, 87% (n = 151); stage III, 72% (n = 92). The predominant pattern of tumor recurrence was distant failure only. Overall locoregional recurrence (locoregional and locoregional plus distant) at 5 years was 4%. Locoregional recurrence paralleled tumor stage: stage I, 0%; stage II, 2%; stage III, 10%. Of the 12 patients who suffered locoregional recurrence, 9 (75%) had T4 primary tumors, N2 nodal disease, or both. Major and minor complications occurred in 93 patients (29%) including: anastomotic leak or intraabdominal abscess (n = 4, 1%); hemorrhage (n = 8, 3%); cardiac complications (n= 17, 5%); pulmonary embolism (n=4, 10%); death (n=2, 1%). Multivariate analysis (Cox proportional hazards) revealed that the only independent predictor of disease-free survival and locoregional control was tumor stage. CONCLUSION Longterm survival and locoregional control can be achieved for patients with colon cancer, with low morbidity. In the absence of adjacent organ invasion and N2 nodal disease, locoregional recurrence should be a rare event. Just as for rectal cancer, the technical aspects of colectomy for colon cancer deserve renewed attention.
