Abstract
PURPOSE The optimal timing of stoma closure during or after adjuvant chemotherapy for rectal cancer patients undergoing sphincter-preserving surgery remains unknown. This study aimed to investigate the influence of clinical and oncological outcomes depending on the timing of stoma closure. METHODS Between January 2006 and December 2015, we enrolled 244 consecutive rectal cancer patients who underwent curative-intent sphincter-preserving surgery with diverting transverse colostomy and adjuvant chemotherapy. Patients with stoma closure during (During group) adjuvant chemotherapy were compared to those who had stoma closure after adjuvant chemotherapy (After group). RESULTS Parastomal hernia occurred more frequently in the after group than in the during group. (10% vs. 2.9%, p = 0.028). Overall, no significant difference was observed in overall survival (OS) or disease-free survival (DFS) between the two groups (p = 0.911 for OS, p = 0.505 for DFS). However, an inferior OS occurred if reopen surgery was performed within 30 days of stoma closure in the during group, as compared with the after group (p = 0.004). In addition, a marginally poor DFS was observed in the group of patients who received further operations due to 30-day stoma closure complications compared to the other patients (p = 0.07). CONCLUSIONS For rectal cancer patients who underwent sphincter-preserving surgery, attention should be given to avoid 30-day major complications after stoma reversal because patients who require reoperation during adjuvant chemotherapy may have poor long-term survival.

Abstract
PURPOSE The standard initial treatment for metastatic colorectal cancer (mCRC) remains debated. This study investigated whether upfront primary tumor resection (PTR) or upfront systemic therapy (ST) provides better survival outcomes for patients with mCRC. METHODS The PubMed, Embase, Cochrane Library, and ClinicalTrials.gov databases were searched for studies published at any time from January 1, 2004, to December 31, 2022. Randomized controlled trials (RCTs) and prospective or retrospective cohort studies (RCSs) utilizing propensity score matching (PSM) or inverse probability treatment weighting (IPTW) were included. We evaluated overall survival (OS) and short-term (60-day) mortality in these studies. RESULTS After reviewing 3,626 articles, we identified 10 studies including a total of 48,696 patients. OS differed significantly between the upfront PTR and upfront ST arms (hazard ratio [HR] 0.62; 95% CI: 0.57-0.68; p < 0.001). However, a subgroup analysis identified no significant difference in OS in RCTs (HR 0.97; 95% CI: 0.7-1.34; p = 0.83), whereas significant difference in OS occurred between the treatment arms in RCSs with PSM or IPTW (HR 0.59; 95% CI: 0.54-0.64; p < 0.001). Short-term mortality was analyzed in three RCTs, and 60-day mortality differed significantly between the treatment arms (risk ratio [RR] 3.52; 95% CI: 1.23-10.10; p = 0.02). CONCLUSIONS In RCTs, upfront PTR for mCRC did not improve OS and enhanced the risk of 60-day mortality. However, upfront PTR seemed to increase OS in RCSs with PSM or IPTW. Therefore, whether upfront PTR should be used for mCRC remains unclear. Further large RCTs are required.

Abstract
(1) Background: BCC is a sporadic disease that develops in areas of the skin not exposed to the sun. Perianal BCC, which occurs in the anorectal region, accounts for less than 0.2% of all BCC cases. There have been only a few reported cases of the disease, with fewer than 200 cases reported in total. Given the diagnostic challenges and potential for misdiagnosis, we conducted a systematic review of perianal basal cell carcinoma using real-world data to provide comprehensive and detailed information on the disease. (2) Methods: The study was reported based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, 2020. Patients' clinical pathologic features, tumor characteristics, treatment modalities, and outcomes were presented. (3) Results: The results of 41 studies involving 140 patients were analyzed. The most common symptoms reported by patients at presentation were anorectal bleeding, pain, and pruritus. Ulceration was the most frequently observed tumor characteristic. The majority of patients underwent local excision as their primary treatment, with only eight patients experiencing a recurrence. Our analysis did not reveal any statistically significant differences in the outcomes of different treatment modalities. (4) Conclusions: Identifying perianal BCC poses a significant challenge as it closely resembles other anal diseases, thereby making it difficult to differentiate between the different conditions. However, a wide local excision with clear margins is considered an effective treatment option for most patients. Alternative treatments, such as radiotherapy, may be recommended for patients who are unable to undergo surgery.

Abstract
PURPOSE We analyzed the effectiveness, safety, and mid-term oncological outcomes of short-course radiotherapy (SCRT) and oxaliplatin-based consolidation chemotherapy in patients with locally advanced rectal cancer (LARC). METHODS We retrospectively evaluated 64 patients with LARC who underwent SCRT and tegafox (tegafur-uracil/leucovorin plus oxaliplatin) or mFOLFOX-6 (5-fluorouracil, leucovorin, and oxaliplatin) consolidation chemotherapy before surgery between January 2015 and December 2020. Tumor response, patient compliance, toxicity, surgical outcomes, overall survival (OS), and disease-free survival (DFS) were analyzed. RESULTS Sixty-four patients with a mean age of 58.67 years (44 males) were included; 48 (75%) had tumors within 5 cm of the anal verge. Additionally, 93.8% of the patients underwent at least 2 months of chemotherapy, and three required dose reduction. Grade III toxicity occurred in 2 patients, and 10 had a clinical complete response and opted for non-operative management. One patient experienced tumor progression and underwent further treatment without surgery. Among the 53 patients who underwent surgery, 51 (96.2%) had sphincter preservation, 3 had Clavien-Dindo grade III complications, and no mortality occurred. The complete response rate for the entire cohort was 23.4%. Moreover, 47 patients (74.6%) had a neoadjuvant rectal score of < 16 after treatment. After a median follow-up time of 32.01 months, 6 (9.3%) had local recurrence, and 17 (26.6%) had distant metastasis. The 3-year OS, DFS and stoma-free rates were 89.5%, 65.5%, and 78.1% respectively. CONCLUSION SCRT followed by oxaliplatin-based consolidation chemotherapy is safe and effective for tumor downstaging in LARC, further improving the sphincter preservation rate.

Abstract
The primary treatment for metastatic colorectal cancer (mCRC) consists of targeted therapy and chemotherapy to improve survival. A molecular target drug with an anti-epidermal growth factor receptor (EGFR) antagonist is recommended when the RAS and BRAF genes are normal. About 50–70% of patients using anti-EGFR antagonists will experience skin reactions. Some studies have shown that severe skin reactions caused by anti-EGFR antagonists may be linked to overall survival (OS) and progression-free survival (PFS), but the results are still uncertain. These data of mCRC patients who underwent anti-EGFR therapy between October 2017 and October 2018 were analyzed retrospectively. A total of 111 patients were included in this study. The survival results showed that gender, age, body mass index, primary tumor site, and recurrence did not significantly affect OS and PFS. However, the first-line anti-EGFR inhibitor treatment was significantly associated with OS (p < 0.001) and PFS (p < 0.001). There was no significant difference in the incidence of acne between males and females in grades 1 and 2, while males have a greater risk in grades 3 and 4 than females (20.3 vs. 4.8%; p-value = 0.041). Skin toxicity was not a predictor of anti-EGFR treatment response in this investigation.

Abstract
BACKGROUND Whether to ligate the inferior mesenteric artery at its root during anterior resection for sigmoid colon or rectal cancer is still under debate. This study compared the surgical outcomes, postoperative recovery, and anastomotic leakage between high and low ligation of the inferior mesenteric artery through a subgroup analysis. METHODS This was a retrospective analysis of prospectively collected data. All patients who underwent colorectal resection for rectosigmoid cancer between December 2016 and December 2019 were enrolled. According to the surgical ligation level of the inferior mesenteric artery, the patients were categorized into either the high or low ligation group. The investigated population was matched using the propensity score method. RESULTS Overall, 894 patients with sigmoid or rectal cancer underwent elective anterior resection with high (577 patients) or low (317 patients) ligation of the inferior mesenteric artery. After the propensity score matching, 245 patients in each group were compared. High ligation of the inferior mesenteric artery was associated with higher incidence of anastomotic leakage (14.9% vs. 5.6%, P = 0.041) for mid- to low-rectum tumors and a higher incidence of complications (8.6% vs. 3.3%, P = 0.013) of grades 1-2 according to the Clavien-Dindo classification system. CONCLUSION Compared with high ligation, low ligation of the inferior mesenteric artery resulted in lower likelihood of morbidity and mortality in rectal and sigmoid cancers. Moreover, low ligation was less likely to result in anastomosis leakage in mid- to low-rectal cancers.

Inflammatory reactions play a crucial role in cancer progression and may contribute to systemic inflammation. In routine clinical practice, some inflammatory biomarkers can be utilized as valuable predictors for colorectal cancer (CRC). This study aims to determine the usefulness of a novel cancer-inflammation prognostic index (CIPI) marker derived from calculating carcinoembryonic antigen (CEA) multiplied by the neutrophil-to-lymphocyte ratio (NLR) values established for non-metastatic CRCs. Between January 1995 and December 2018, 12,092 patients were diagnosed with stage I to III primary CRC and had radical resection—they were all included in this study for further investigation. There were 5996 (49.6%) patients in the low-CIPI group and 6096 (50.4%) patients in the high-CIPI group according to the cutoff value of 8. For long-term outcomes, the high-CIPI group had a significantly higher incidence of recurrence (30.6% vs. 16.0%, p < 0.001) and worse relapse-free survival (RFS) and overall survival (OS) rates (p < 0.001). High CIPI was an independent prognostic factor for RFS and OS in univariate and multivariate analyses. This research is the first to document the independent significance of CIPI as a prognostic factor for CRC. To ensure that it works, this CIPI needs to be tested on more CRC prediction models.

Abstract
It is controversial whether patients who achieve clinical complete remission (cCR) of rectal cancer should be treated with the “watch and wait” (W&W) or radical resection (RR) strategy. Our study aimed to compare the survival outcomes and ostomy rate of the W&W and RR strategies. Between January 2008 and December 2015, we investigated 26 patients who achieved pathologic complete remission after undergoing RR and 36 patients who adopted the W&W strategy because of cCR. The tumor regrowth, salvage surgery, recurrence, disease-free, and overall survival (OS) rates were assessed. In our study, recurrences occurred in nine and two patients from the W&W and RR groups, respectively. Each patient in the RR group had a temporary or permanent ostomy, but only three (8.3%) had an ostomy in the W&W group. The 5-year recurrence rate was 25.0% in the W&W group and 7.7% in the RR group. Six patients (16.7%) had tumor regrowth in the W&W group, and all were resectable when regrowth. The 5-year OS rates between the two groups were nonsignificant. There is no specific risk factor for recurrence and OS. Under close surveillance, the W&W group achieved similar OS to the RR group and benefited from a lower ostomy rate.

Abstract
BACKGROUND Few studies have evaluated the feasibility and safety of intracorporeal anastomosis (IA) for left hemicolectomy. Here, we aimed to investigate the potential advantages and disadvantages of laparoscopic left hemicolectomy with IA and compare the short- and medium-term outcomes between IA and extracorporeal anastomosis (EA). METHODS We retrospectively analyzed 133 consecutive patients who underwent laparoscopic left hemicolectomies from July 2016 to September 2019 and categorized them into the IA and EA groups. Patients with stage 4 disease and conversion to laparotomy or those lost to follow-up were excluded. Postoperative outcomes between IA and EA groups were compared. Short-term outcomes included postoperative pain score, bowel function recovery, complications, duration of hospital stay, and pathological outcome. Medium outcomes included overall survival and disease-free survival for at least 2 years. RESULTS After excluding ineligible patients, the remaining 117 underwent IA (n = 40) and EA (n = 77). The IA group had a shorter hospital stay, a shorter time to tolerate liquid or soft diets, and higher serum C-reactive protein level on postoperative day 3. There was no difference between two groups in operative time, postoperative pain, specimen length, or nearest margin. A 2-year overall survival (IA vs. EA: 95.0% vs. 93.5%, p = 0.747) and disease-free survival (IA vs. EA: 97.5% vs. 90.9%, p = 0.182) rates were comparable between two groups. CONCLUSIONS Laparoscopic left hemicolectomy with IA was technically feasible, with better short-term outcomes, including shorter hospital stays and shorter time to tolerate liquid or soft diets. The IA group had higher postoperative serum C-reactive protein level; however, no complications were observed. Regarding medium-term outcomes, the overall survival and disease-free survival rates were comparable between IA and EA procedures.

Abstract
This study aimed to explore the safety and efficacy of neoadjuvant SCRT and tegafur−uracil/leucovorin plus oxaliplatin (TEGAFOX) for LARC in comparison to those of the modified 5-fluorouracil, leucovorin, and oxaliplatin (mFOLFOX-6) regimen. We retrospectively evaluated 15 and 22 patients with LARC who underwent SCRT, followed by consolidation chemotherapy with TEGAFOX and mFOLFOX-6 before surgery, respectively, between January 2015 and December 2019. The primary endpoint was the tumor response rate. The secondary endpoints were compliance, toxicity, complications, overall survival (OS), and disease-free survival (DFS). The dose reduction rate was lower in the TEGAFOX group (0 vs. 9.1% (n = 2)). No grade III-IV toxicities occurred in the TEGAFOX group. Two and four patients in the TEGAFOX and mFOLFOX-6 groups, respectively, achieved clinical complete responses. The pathologic complete response rate was lower in the TEGAFOX group (7.7% vs. 17.6%). Overall, 11 (73.3%) and 17 (81.0%) patients had a neoadjuvant rectal (NAR) score of <16 in the TEGAFOX and mFOLFOX-6 groups, respectively. All patients in this study received sphincter-preservation surgery. One patient in each group developed Clavien−Dindo grade III complications. There were no significant between-group differences in the 3-year OS (81.8% vs. 84.8%, p = 0.884) and 3-year DFS (72% vs. 71.6%, p = 0.824) rates. TEGAFOX, as consolidation chemotherapy after SCRT, achieves good tumor downstaging and patient compliance in LARC. The toxicity, complications, and surgical outcomes are similar to those of mFOLFOX-6. Thus, TEGAFOX can be considered a chemotherapy option for rectal cancer treatment.

Abstract
Neoadjuvant short course radiotherapy (SCRT) followed by consolidation chemotherapy (CCT) is an alternative treatment for locally advanced rectal cancer (LARC). We performed this systematic review and meta-analysis to explore the tumor response and oncological outcomes of this new approach compared to conventional chemoradiotherapy (CRT). An online search of the PubMed, Embase, and Cochrane Library databases was performed. This review included 7507 patients from 14 different cohorts. The pCR rate was higher with SCRT + CCT than that with CRT (RR: 1.60; 95% CI: 1.35−1.91; p < 0.01). SCRT + CCT provided a higher ypN0 response (RR: 1.06; 95% CI: 1.01−1.12; p = 0.02). There were no differences in R0 resection and positive CRM rates; however, more sphincter-preservation surgeries were performed in the SCRT + CCT arm (RR: 1.06; 95% CI: 1.01−1.11; p = 0.02). There was no difference in the OS and DFS between the SCRT + CCT and the CRT arms (OS: HR: 0.85, p = 0.07; DFS: HR: 0.88, p = 0.08). The compliance and toxicity were comparable between the SCRT and CRT groups. In the subgroup analysis, patients who underwent four or more cycles of CCT had better pCR and DFS events. Therefore, SCRT followed by consolidation chemotherapy might be an effective alternative treatment for LARC.

Abstract
Malnutrition and systemic inflammatory response (SIR) frequently occur in patients with colorectal cancer (CRC) and are associated with poor prognosis. Anti-inflammatory nutritional intervention is not only a way to restore the malnourished status but also modulate SIR. Nine experts, including colorectal surgeons, physicians and dieticians from 5 hospitals geographically distributed in Taiwan, attended the consensus meeting in Taiwan Society of Colon and Rectum Surgeons for a 3-round discussion and achieved the consensus based on a systematic literature review of clinical studies and published guidelines. The consensus recommends that assessment of nutritional risk and SIR should be performed before and after CRC treatment and appropriate nutritional and/or anti-inflammatory intervention should be adapted and provided accordingly.

Abstract
AIM Laparoscopic anterior resection with natural orifice specimen extraction (NOSE) has favourable short-term outcomes. However, NOSE is rarely adopted for left hemicolectomy procedures. This study aimed to review the feasibility, safety and short-term outcomes of transrectal NOSE in patients undergoing laparoscopic left hemicolectomy. METHOD All consecutive patients who underwent laparoscopic left hemicolectomy surgery with transrectal NOSE in a single institution between January 2018 and December 2020 were reviewed. Transrectal NOSE was performed with an enterotomy at the upper rectum. The specimen was brought out via a transanal endoscopic microsurgery scope inserted through the anus. A supplementary video demonstrates this technique. Surgical outcomes, including complications, postoperative short-term recovery and the level of pain intensity, are presented. RESULTS Twenty patients were reviewed. There were no immediate postoperative complications and no wound infections in these patients. The average time to tolerate a soft diet was 3.6 days, and the average postoperative hospital stay was 4.5 days. The average score on the numerical rating scale of postoperative pain was 3.0 on postoperative day 1. The median follow-up time was 23.5 months. CONCLUSION Laparoscopic left hemicolectomy with transrectal NOSE is a safe and feasible procedure that leads to early postoperative recovery and a short hospital stay.

Abstract
Simple Summary As the effect of laparoscopic surgery on elderly patients with colorectal cancer (CRC) remains unclear, this propensity score–weighted cohort study revealed that laparoscopic surgery is a favorable method for elderly patients with CRC than open surgery in terms of less pulmonary-related postoperative morbidity and mortality, less hospital stay and similar oncological outcomes. Abstract Advanced age is a risk factor for major abdominal surgery due to a decline in physical function and increased comorbidities. Although laparoscopic surgery provides good results in most patients with colorectal cancer (CRC), its effect on elderly patients remains unclear. This study aimed to compare the short- and long-term outcomes between open and laparoscopic surgeries in elderly patients with CRC. Total 1350 patients aged ≥75 years who underwent curative resection for stage I–III primary CRC were enrolled retrospectively and were divided into open surgery (846 patients) and laparoscopy (504 patients) groups. After propensity score weighting to balance an uneven distribution, a competing risk analysis was used to analyze the short-term and long-term outcomes. Postoperative mortality rates were lower in the laparoscopy group, especially due to pulmonary complications. Postoperative hospital stay was significantly shorter in the laparoscopy group than in the open surgery group. Overall survival, disease-free survival, and competing risk analysis showed no significant differences between the two groups. Laparoscopic surgery for elderly patients with CRC significantly decreased pulmonary-related postoperative morbidity and mortality in this large cohort study. Laparoscopic surgery is a favorable method for elderly patients with CRC than open surgery in terms of less hospital stay and similar oncological outcomes.

Abstract
(1) Background: The aim of this study was to develop a prediction model for assessing individual mPC risk in patients with pT4 colon cancer. Methods: A total of 2003 patients with pT4 colon cancer undergoing R0 resection were categorized into the training or testing set. Based on the training set, 2044 Cox prediction models were developed. Next, models with the maximal C-index and minimal prediction error were selected. The final model was then validated based on the testing set using a time-dependent area under the curve and Brier score, and a scoring system was developed. Patients were stratified into the high- or low-risk group by their risk score, with the cut-off points determined by a classification and regression tree (CART). (2) Results: The five candidate predictors were tumor location, preoperative carcinoembryonic antigen value, histologic type, T stage and nodal stage. Based on the CART, patients were categorized into the low-risk or high-risk groups. The model has high predictive accuracy (prediction error ≤5%) and good discrimination ability (area under the curve >0.7). (3) Conclusions: The prediction model quantifies individual risk and is feasible for selecting patients with pT4 colon cancer who are at high risk of developing mPC.

Abstract
BACKGROUND Marfan syndrome is rarely accompanied by anterior sacral meningocele (ASM) resulting from erosion of the sacrum by dural ectasia. ASM may induce symptoms due to severe mass effects. ASM may also mimic ovarian cysts, and the risk of cerebrospinal fluid (CSF) leakage is high if spontaneous rupture of the cyst occurs. In this study, the authors presented a rare case of ASM with iatrogenic CSF leakage in a 34-year-old woman with suspected Marfan syndrome. OBSERVATIONS The patient initially presented with a giant ASM that was first misdiagnosed as an ovarian cyst. Previously, it had been partially resected, which was followed by iatrogenic CSF leakage. Symptoms of intracranial hypotension, including postural headache and dizziness, developed within 1 month. Brain magnetic resonance imaging (MRI) showed pituitary enlargement, bilateral subdural effusion, and tonsillar herniation. Preoperative computed tomography myelography provided three-dimensional (3D) examination of the deformed sacrum and CSF leakage site. Transabdominal approaches led to primary repair, and repair of the meningocele was achieved by intraoperative fluorescein fluorescence and 3D printed model–guided polymethyl methacrylate bone cement reconstruction. No CSF leakage or recurrent ASM was found at the 1.5-year follow-up visit. LESSONS Intraoperative intrathecal fluorescence and 3D-printed models are useful for ASM repair. Preoperative MRI is helpful for differentiating ASM from other causes of a huge pelvic mass, including ovarian cyst.

Abstract
Background Radical resection is associated with good prognosis among patients with cT1/T2Nx rectal cancer. However, still some of the patients experienced cancer recurrence following radical resection. This study tried to identify the postoperative risk factors of local recurrence and distant metastasis separately. Methods This retrospective, single-center study comprised of 279 consecutive patients from Linkou branch of Chang Gung Memorial Hospital in 2005–2016 with rectal adenocarcinoma, pT1/T2N0M0 at distance from anal verge ≤ 8cm, who received curative radical resection. Results The study included 279 patients with pT1/pT2N0 mid-low rectal cancer with median follow-up of 73.5 months. Nineteen (6.8%) patients had disease recurrence in total. Nine (3.2%) of them had local recurrence, and fourteen (5.0%) of them had distant metastasis. Distal resection margin < 0.9 (cm) (hazard ratio = 4.9, p = 0.050) was the risk factor of local recurrence. Preoperative carcinoembryonic antigen (CEA) ≥ 5 ng/mL (hazard ratio = 9.3, p = 0.0003), lymph node yield (LNY) < 14 (hazard ratio = 5.0, p = 0.006), and distal resection margin < 1.4cm (hazard ratio = 4.0, p = 0.035) were the risk factors of distant metastasis. Conclusion For patients with pT1/pT2N0 mid-low rectal cancer, current multidisciplinary treatment brings acceptable survival outcome. Insufficient distal resection margin attracted the awareness of risk factors for local recurrence and distant metastasis as a foundation for future research.

Abstract
BACKGROUNDS Though better short-term outcomes were frequently reported, differences in specimen parameters and the rate of subsequent peritoneal recurrence between intracorporeal anastomosis (IA) and extracorporeal anastomoses (EA) for laparoscopic right hemicolectomy have not been analyzed. We aimed to compare the pathologic differences and oncological outcomes between these two approaches. METHODS We retrospectively analyzed 217 consecutive patients who underwent laparoscopic right hemicolectomies from September 2016 to April 2018 and classified them into IA and EA groups, based on the approach used. Propensity score matching analysis was performed, after which 101 patients were included in each group with the patients matched for demographics, tumor stage, and localization. RESULTS The IA group had a longer operative time, shorter length of stay, shorter time to first flatus and tolerating a soft diet, and better pain scale scores at postoperative day 3. No inter-group differences in conversion, postoperative complication, mortality, or readmission rates were found. The IA group had a longer resected colon length (23.67 vs. 19.75 cm, p = 0.010) and nearest resected margin (7.51 vs. 5.40 cm, p = 0.010) for cancer near the hepatic flexure. There are comparable 3-year overall survival (87.7% vs. 89.6%, p = 0.604) and disease-free survival (75.0% vs. 75.7%, p = 0.842) between the IA and EA groups. The rate of peritoneal recurrence was similar between the two groups (5.9% vs. 7.9%, p = 0.580). CONCLUSIONS The overall survival, disease-free survival, and the rate of peritoneal recurrence were comparable between the IA and EA procedures. IA ensures better recovery and comparable complications to EA and achieved a more precise tumor excision; thus, IA can be considered a safe procedure for patients with right-sided colon lesions.

Abstract
Background Local excision (LE) is a feasible treatment approach for rectal cancers in stage pT1 and presents low pathological risk, whereas total mesorectal excision (TME) is a reasonable treatment for more advanced cancers. On the basis of the pathology findings, surgeons may suggest TME for patients receiving LE. This study compared the survival outcomes between LE with/without chemoradiation and TME in mid and low rectal cancer patients in stage pT1/pT2, with highly selective intermediate pathological risk. Methods This retrospective study included 134 patients who received TME and 39 patients who underwent LE for the treatment of intermediate risk (pT1 with poor differentiation, lymphovascular invasion, perineural invasion, relatively large tumor, or small-sized pT2 tumor) rectal cancer between 1998 and 2016. Results Overall survival (OS), disease-free survival (DFS), and cumulative recurrence rate (CRR) were similar between the LE (3-year DFS 92%) and TME (3-year DFS 91%) groups. Following subgrouping into an LE with adjuvant therapy group and a TME without adjuvant therapy group, the compared survival outcomes (OS, DFS, and CRR) were found not to be statistically different. The temporary and permanent ostomy rates were higher in the TME group than in the LE group (p < 0.001). Rates of early and late morbidity following surgery were higher in the TME group (p = 0.005), and LE had similar survival compared with TME. Conclusion For patients who had mid and low rectal cancer in stage pT1/pT2 and intermediate pathological risk, LE with chemoradiation presents an alternative treatment option for selected patients.

Abstract
BACKGROUND Preoperative carcinoembryonic antigen (CEA) has yet to be used as a prognostic or adjuvant chemotherapy factor for colorectal cancer (CRC). METHODS This retrospective cohort study included all stage I-III CRC patients with different preoperative serum CEA levels (≤ 5, 5-10, and > 10 ng/ml) at a single center between 1995 and 2010. Propensity score matching was performed in a 1:1 ratio between the two elevated CEA groups (5-10 ng/ml and > 10 ng/ml) and in a 1:2 ratio between the elevated and non-elevated groups (≤ 5 ng/ml), with a caliper of 0.05. RESULTS After exclusion and matching, 3857 patients had preoperative CEA levels ≤ 5 ng/ml, 1121 patients had CEA levels between 5 and 10 ng/ml, and 1121 patients had CEA levels > 10 ng/ml. Elevated preoperative CEA showed an increased risk of overall survival (5-10 ng/ml: hazard ratio [HR] 1.376; > 10 ng/ml: HR 1.523; both p < 0.001), cancer-specific survival (5-10 ng/ml: HR 1.404; > 10 ng/ml: HR 1.712; both p < 0.001), and recurrence free interval (5-10 ng/ml: HR 1.190; > 10 ng/ml: HR 1.468; both p < 0.05). Patients with negative lymph node staging (LNs) and CEA > 10 ng/ml, as well as those with positive LNs and CEA ≤ 5 ng/ml, showed similar overall survival (5-year survival: 72% vs. 69%; p = 0.542) and recurrence free intervals (19.9 vs. 21.72 months; p = 0.662). CONCLUSIONS A preoperative CEA level can be an independent prognostic factor for stage I-III CRC after curative resection. Patients with negative LNs and preoperative CEA level > 10 ng/ml should be considered for intensive follow-up or adjuvant chemotherapy.

Abstract
BACKGROUND AND OBJECTIVES We aim to investigate whether a difference exists between right-sided and left-sided colon cancer at the same disease stage and subsequent liver metastasis and identify whether tumor location can independently influence survival. METHODS Right-sided colon cancer was defined as malignancy arising from the cecum to the transverse colon; left-sided colon cancer was defined as malignancy arising from the splenic flexure to the sigmoid colon. Clinicopathological features and survival data were collected for analysis. RESULTS Overall, 1442 patients were included for analysis. The median follow-up time was 58.2 months. Patients with left-sided colon cancer had better 5-year overall survival (75.2% vs 61.7%, P = 0.005), 5-year cancer-specific survival (81.6% vs 73.4%, P = 0.001), and 5-year recurrence-free survival (70.9% vs 66.5%, P = 0.033) compared with patients having right-sided colon cancer. After the presentation of subsequent liver metastasis, patients with primary left-sided colon cancer had better 3-year cancer-specific survival ( P < 0.001). In the multivariate analysis, cancer location was an independent prognostic factor for cancer-specific survival (right vs left, HR: 1.276, 95% CI: 1.002-1.625). CONCLUSIONS The primary tumor location can serve as a prognostic factor for treatment outcomes either in primary stage III colon cancer or subsequent liver metastasis.

Abstract
PURPOSE The rate of postoperative morbidity and mortality is reportedly high in patients aged ≥ 75 years with colorectal cancer (CRC). In such patients, a comparison of the short-term outcome between open method and laparoscopy has not been clearly defined in Taiwan. We aimed to compare postoperative morbidity and mortality parameters after open method and laparoscopy in CRC patients aged ≥ 75 years. METHODS We retrospectively analyzed patients who underwent surgery for CRC from February 2009 to September 2015 at the Linkou Chang Gung Memorial Hospital in Taiwan and analyzed their clinicopathological factors. Postoperative morbidity and mortality were analyzed for evaluating if laparoscopic surgery offers more favorable outcomes than open surgery in the elderly. RESULTS A total of 1133 patients were enrolled and analyzed in this study; they were divided into two groups (open method vs. laparoscopy = 797 vs. 336). The anastomotic leakage rate was significantly higher in the laparoscopy group than in the open method group (3.3 vs. 0.9%, p = 0.003). Overall postoperative morbidity and mortality rates showed no significant difference between these two groups. Postoperative hospital stay was significantly shorter in the laparoscopy group than in the open method group (10.4 ± 8.7 vs. 13.8 ± 13.5 days, p < 0.001). CONCLUSIONS Our results suggest that laparoscopy in patients aged ≥ 75 years with CRC had higher anastomosis leakage rate compared with open surgery but is acceptable and offers the benefit of a shorter hospital stay over open surgery.

Abstract
BACKGROUNDS Clinicopathologic factors relating to developing metachronous colorectal cancer (CRC) have been reported. However, the effects of different diagnostic intervals on these risk factors required further analysis. PATIENTS AND METHODS This retrospective study comprised 14,481 patients diagnosed from January 1995 to December 2012. Metachronous CRC was defined as the occurrence of a second colorectal cancer at least 1 year post-operatively. RESULTS A total of 153 (1.06%) patients developed metachronous CRCs during the follow-up. Significantly higher rates of developing metachronous cancer occurred in male patients (1.2 vs 0.9%), patients with synchronous CRC (2.0 vs 1.0%), and patients with a positive family history of CRC (1.4 vs 0.9%). Pertaining to diagnostic intervals related to clinicopathological features, more severe staging was significant in the diagnostic interval between 2 and 3 years (35 vs 7.7%, 20.6%, 17.5%, P = .01) compared with other intervals. Male patients were more frequently detected to have CRC within 3 years compared with females (53.1 vs 29.1%, P = .005). For a diagnostic interval ≧ 5 years, a significantly higher rate of metachronous CRC located at the right colon was observed than that located at the left colon (36.6 vs 19.7%, p = 0.03). CONCLUSIONS We evinced that a diagnostic interval between 2 and 3 years was a key time for metachronous CRC diagnosis with worse staging distribution. Based on current findings, we recommend the stratification of metachronous CRCs into diagnostic intervals of 1-2, 2-3, and ≧ 3 years, as they exhibit significantly different characteristics.

Abstract
Background Colonic lymphoma is an uncommon presentation of extranodal lymphoma. Colonic mucosa-associated lymphoid tissue lymphoma is a different entity from gastric mucosa-associated lymphoid tissue lymphoma, and very rare. The presentation and management of colonic mucosa-associated lymphoid tissue are highly variable in the literature. Case presentation We report the case of a 59-year-old Taiwanese man who underwent a colonoscopy after a positive test for fecal occult blood. His past history included hypertension and hyperthyroidism. The colonoscopy revealed an adenomatous polyp and mucosa-associated lymphoid tissue lymphoma. We successfully performed a polypectomy and endoscopic mucosal resection. The lymphoma was staged according to the Ann Arbor system modified by Musshoff as E-I. Our patient showed no lymphoma recurrence over a 3-year follow-up. Conclusions Endoscopic mucosal resection for colonic mucosa-associated lymphoid tissue lymphoma without disseminated disease may be feasible. We successfully used colonoscopic treatment without adjuvant therapy to treat early-stage pathogen-free colonic mucosa-associated lymphoid tissue lymphoma.

Abstract
The quantitative relationship between serum albumin level and surgical outcomes has not been clearly established. This study included 3732 patients with colon cancer who underwent a potentially curative colectomy. Post-operative mortality and morbidity were analysed according to the patients' demographic data, pre-operative comorbidities, and tumour-related factors. Age, asthma, renal impairment, and albumin level were significantly associated with post-operative morbidity and mortality in the multivariate analyses. Logistic regression analysis revealed linear relationships of post-operative morbidity and mortality with albumin level. The morbidity and mortality rates decreased by 7.3% and 15.6%, respectively, for each 0.1 g/dL increase in albumin level. This finding remained significant in the hypoalbuminaemia subgroup but not in the normoalbuminaemia subgroup. That is, the morbidity and mortality rates significantly decreased by 8.7% and 17.7%, respectively (both P < 0.001), in the former group and decreased by 2.7% (P = 0.112) and 11.6% (P = 0.092), respectively, in the latter group. This study demonstrated that serum albumin level linearly predicted the post-operative morbidity and mortality among the colorectal cancer patients. Pre-operative serum albumin level may therefore be used as a continuous rather than a categorical marker of disease severity, especially among patients with hypoalbuminaemia.

Abstract
Colorectal cancer (CRC) is a genetically heterogeneous disease with distinct morphological patterns. It has been shown that polypoid and ulcerative CRC displays different genetic alterations. In the present study, we aimed to investigate genes with differential expression patterns between ulcerative and polypoid CRC. cDNA microarray analysis was performed to compare the gene expression profiles in samples of ulcerative and polypoid CRC with paired normal mucosa samples. Potential candidate genes were further validated using reverse transcription-quantitative polymerase chain reaction (RT-qPCR), western blot analysis and immunohistochemistry. The epigenetic regulation of gene expression was investigated using methylation-specific PCR (MSP). cDNA microarray analysis identified 11 upregulated and 14 downregulated genes which were differentially expressed in samples from both tumor types compared to the matched normal mucosa samples. Among these, S100P was the only upregulated gene preferentially associated with polypoid CRC (P=0.032). The samples of polypoid CRC displayed significantly higher S100P protein and mRNA expression levels than the samples of ulcerative CRC (P<0.05, respectively). Using semi-quantitative immunohistochemical analyses, S100P overexpression was found to be preferentially associated with polypoid CRC (24/30 vs. 14/40, P<0.001). The relative methylation level determined by MSP did not differ significantly between the samples of polypoid and ulcerative CRC (43.36 vs. 49.10%, P=0.168), indicating that promoter hypomethylation was not directly related to the upregulation of S100P mRNA. Our results demonstrate that the upregulation of S100P mRNA and protein expression is a predominant characteristic in polypoid CRC, whereas ulcerative CRC presents with a wide range of expression levels, indicating that S100P overexpression is not a key determinant in conferring invasion properties. The clinicopathological significance of S100P in CRC requires further investigation in well-controlled studies.

Abstract
Three-dimensional (3D) cellular spheroids have recently emerged as a new trend to replace suspended single cells in modern cell-based therapies because of their greater regeneration capacities in vitro. They may lose the 3D structure during a change of microenvironment, which poses challenges to their translation in vivo. Besides, the conventional microporous scaffolds may have difficulty in accommodating these relatively large spheroids. Here we revealed a novel design of microenvironment for delivering and sustaining the 3D spheroids. Biodegradable scaffolds with macroporosity to accommodate mesenchymal stem cell (MSC) spheroids were made by solid freeform fabrication (SFF) from the solution of poly(D,L-lactide-co-glycolide). Their internal surface was modified with chitosan following air plasma treatment in order to preserve the morphology of the spheroids. It was demonstrated that human MSC spheroids loaded in SFF scaffolds produced a significantly larger amount of cartilage-associated extracellular matrix in vitro and in NOD/SCID mice compared to single cells in the same scaffolds. Implantation of MSC spheroid-loaded scaffolds into the chondral defects of rabbit knees showed superior cartilage regeneration. This study establishes new perspectives in designing the spheroid-sustaining microenvironment within a tissue engineering scaffold for in vivo applications.

Abstract
BACKGROUND/AIMS To evaluate outcome and prognostic factors of patients with anorectal melanoma. METHODOLOGY Twenty-two consecutive patients with anorectal melanoma received operation from 1993 through 2011 were reviewed. The definitions of stage I, II and III are local disease, locoregional lymphadenopathy and metastatic disease, respectively. RESULTS The patients included 8 men and 14 women, aged from 36 to 83 years (mean, 58.4 years). At the end of the follow-up period, 19 patients died of disease and only 3 patients were alive with disease. Only two patients were alive longer than 5 years after operation. For stage I and II tumors that underwent clinical curative resection (n=17), stage II (p=0.04), tumor size >3 cm (p=0.008) and invasion depth to muscle (p=0.021) all showed poorer prognosis in overall survival. Though wide local excision (WLE) were performed in the patients with earlier tumors, there was no statistical difference in overall (p=0.063) and disease-free survival (p=0.333) between WLE and radical surgery. Furthermore, patients with WLE had more chance of local recurrence than radical surgery (6/7 vs. 3/10, p=0.050). Four salvage radical operations could be performed after local recurrence in WLE group. CONCLUSIONS WLE increases the chance of local recurrence more than radical surgery. Care should be taken to avoid microseeding during performed WLE.

Abstract
BACKGROUND/AIMS Long course concurrent chemoradiotherapy provides potential tumor downstaging. When local recurrent rectal cancer without distant metastases is diagnosed, a potentially curative resection can be performed. The aim of this study was to assess the outcome of concurrent chemoradiotherapy in treating isolated local recurrent rectal cancer. METHODOLOGY Patients (n=102) with isolated local recurrent rectal cancer within the pelvis were scheduled for concurrent chemoradiotherapy, consisting of pelvic irradiation with a total dose of 50.4 Gy in 28 fractions. Chemotherapy was administered concurrently and included 85 mg/m2 oxaliplatin by venous infusion over 2 h on day 1, followed by 1,200 mg*m-2*day-1 of continuous venous infusion for 2 days. This regimen was repeated every 2 weeks for 6 cycles. The overall survival rate, responses, disease-free interval and toxicities were assessed. RESULTS A total of 96 patients completed planned concurrent chemoradiation. Complete clinical responses were found in 13 of the 96 patients (14%), partial responses in 59 (61%), stable disease in 21 (22%) and disease progression in 3 (3%). The overall survival and disease-free survival rates in all the 96 patients were 45% and 14%, respectively. CONCLUSIONS The treatment of locally recurrent rectal cancer is complicated. Concurrent chemoradiation can increase disease-free survival and overall survival by increasing complete resection rate of locally recurrent tumors and even complete response of the tumors. Ongoing treatment strategies aim to enhance response rates and to accurately assess the extent of local recurrent tumor response to concurrent chemoradiation.

Abstract
BACKGROUND/AIMS Predicting the lymph node metastatic or distant metastatic potential of T1 adenocarcinoma of the colon and rectum remains a major challenge. We investigated the role of the expressions of tumor matrilysin (MMP-7), VEGF-C and VEGF-A in predicting these metastatic potentials. METHODOLOGY Single T1 adenocarcinomas were examined and pathological tumor factors were reviewed. Immunohistochemical staining of VEGF and MMP-7 was performed and the metastatic potential was defined on the basis of the presence of lymph nodes in the specimen or the identification of other distant metastasis during follow-up examinations. RESULTS There was little correlation between the IHC staining results of VEGF-A, VEGF-C and MMP-7 in the same specimen (kappa<0.1). After a 61-month median follow-up (2-131 months), 17 (11.8%) tumors showed metastatic potential, including 14 lymph node metastases and 3 distant metastases. The tumors showing high levels of MMP-7 expression had higher metastatic potentials than those with low expression (19.1% vs. 8.2%, respectively; p=0.057). Overexpression of MMP-7 generally indicated an inferior overall survival (p=0.09). In analysis of the traditional pathological tumor factors, only lymphovascular invasion showed significance in predicting metastatic potential (p=0.04). CONCLUSIONS Overexpression of MMP-7 generally indicated a higher metastatic potential and inferior overall survival. Lymphovascular invasion was a significant risk factor for lymph node metastasis.

Abstract
BACKGROUND Local excision has become an alternative for radical resection in rectal cancer for selected patients. The purpose of this study was to assess the clinicopathologic factors determining lymph node metastasis (LNM) in patients with T1-2 rectal cancer. METHODS Between January 1995 and December 2009, a total of 943 patients with pT1 or pT2 rectal adenocarcinoma received radical resection at a single institution. Clinicopathologic factors were evaluated by univariate and multivariate analyses to identify risk factors for LNM. RESULTS A total of 943 patients (544 men and 399 women) treated for T1-2 rectal cancer were included in this study. LNM was found in 188 patients (19.9%). In multivariate analysis, lymphovascular invasion (LVI; P < 0.001, hazard ratio 11.472), poor differentiation (PD; P = 0.007, hazard ratio 3.218), and depth of invasion (presence of pT2; P = 0.032, hazard ratio 1.694) were significantly related to nodal involvement. The incidence for LNM lesions in the presence of LVI, PD, and pT2 was 68.8, 50.0, and 23.1%, respectively, while that for pT1 carcinomas with no LVI or PD was 7.5%. CONCLUSIONS LVI, PD, and pT2 are independent risk factors predicting LNM in pT1-2 rectal carcinoma.

Abstract
UNLABELLED BACKGROUND /AIMS: The aim of this study was to calculate the prevalence of elevated carcinoembryonic antigen (CEA) among colorectal cancer (CRC) patients and to evaluate the prognostic value of preoperative serum CEA levels in them. METHODOLOGY Between 1995 and 2005, 8,861 consecutive patients were enrolled from a prospective database. CEA =5ng/mL was defined as elevated CEA. RESULTS In the multivariate analysis, elevated preoperative CEA correlated with higher ages, circumferential tumors, colon tumors, large tumors, liver metastasis and high-stage (AJCC) tumors. After a 44-month median follow-up, elevated CEA was found to be an independent prognostic factor (odds ratio = 1.61) for overall survival in all 4 stages of the disease. The survival among patients with stage I tumors and elevated CEA (5-year survival rate = 74.7%) was not greater than that among patients with stage II tumors and no CEA elevation (5-year survival rate = 80.8%). CONCLUSIONS Elevated preoperative CEA correlated with a higher age, circumferential tumors, colon tumors, large tumors, liver metastasis, and high-stage (AJCC) tumors. Elevated preoperative CEA indicates a potential poor prognosis even in early stage tumors. This poorer prognosis in the patients with stage I tumors and elevated preoperative CEA was not cancer specific.

Abstract
BACKGROUNDS AND AIMS To elucidate the survival benefits of adjuvant chemotherapy by decreasing incidence or by delaying time of tumor recurrence, we reported the long-term results of a nonrandomized prospective study comparing the adjuvant chemotherapy to no chemotherapy in stage III colorectal cancer. PATIENTS From 1991 to 1995, 463 patients with stage III colorectal cancer were divided to three groups which were no chemotherapy, weekly chemotherapy, and monthly chemotherapy (5-FU plus levamisole). RESULTS The recurrent incidence was significantly decreased in patients with chemotherapy (47.8% vs. 63.9% of no chemotherapy, P = 0.001), resulting into better survival. The 10-year cancer-specific and overall survival rates of patients with chemotherapy vs. no chemotherapy were 52.1% vs. 37.8% and 46.9% vs. 29.9%, respectively (P < 0.001). Weekly chemotherapy had better survival than monthly chemotherapy (P < 0.05). There was no significant difference in recurrent time or types between the patients with and without chemotherapy. The percentages of patients with recurrence happened within 3 years were 85.2% and 84.6% of those with and without chemotherapy, respectively. Patients with advanced stage of T4b invasion depth, N2, and central node invasion had no significant survival benefits by adjuvant chemotherapy. CONCLUSIONS Long-term survival benefits achieved by adjuvant chemotherapy is through decreasing recurrent incidence, not through postponing tumor recurrent time. That means adjuvant chemotherapy indeed cures some patients by eradicating occult tumor. In adjuvant setting, more powerful regimen for eradicating occult tumor is the keystone to improve long-term survival of stage III colorectal cancer.

Abstract
BACKGROUND AND AIMS Selection of appropriate stage II colon cancer patients for adjuvant chemotherapy is critical for improving survival outcome. With the aim of identifying more high risk factors for stage II colon cancer, this study aimed to determine whether the neutrophil-lymphocyte ratio (NLR) is a predictor of surgical outcomes in patients with stage II colon cancer who do not receive adjuvant chemotherapy. MATERIALS AND METHODS We enrolled 1,040 stage II colon cancer patients who had undergone colectomy at a single institution between January 1995 and December 2005 and did not receive adjuvant chemotherapy. RESULTS Of these 1,040 patients, 785 (75.5%) patients had a normal NLR and 255 (24.5%) had an elevated NLR. Those with an elevated NLR included patients ≥65 years, T4b cancer, carcinoembryonic antigen ≥5 ng/mL, and tumor obstruction or perforation. Patients with an elevated NLR had a significantly worse overall survival (OS) and worse disease-free survival (DFS) than did patients with a normal NLR. Cox regression analysis revealed that elevated NLR was an independent predictor of OS (P=0.012) but not DFS (P=0.255). CONCLUSION An elevated NLR is an independent predictor of OS but not DFS in stage II colon cancer patients who did not receive adjuvant chemotherapy. Preoperative NLR measurement in stage II colon cancer patients may be a simple method for identifying patients with a poor prognosis who can be enrolled in further trials of adjuvant chemotherapy.

Abstract
BACKGROUND AND AIMS In locally advanced primary transverse colon cancer, a tumor may cause perforation or invade adjacent organs. Extensive resection is the best choice of treatment, but such procedures must be weighed against the potential survival benefits. This study was performed to identify the clinicopathological features and treatment outcomes of such tumors. MATERIALS AND METHODS We retrospectively reviewed the database of the Colorectal Cancer Registry of Chang Gung Memorial Hospital between February 1995 and December 2005. Patients with colon cancer sited between the hepatic and splenic flexure that involved an adjacent organ without distant metastasis were defined as having locally advanced transverse colon cancer. RESULTS A total of 827 patients who underwent surgery for transverse primary colon cancer were enrolled in the study. Stage II and stage III colon cancer were diagnosed in 548 patients. Thirty-two (5.8%) patients were diagnosed with locally advanced tumors. Multivariate analysis revealed that stage III, preoperative carcinoembryonic antigen ≥5 ng/mL, a tumor with perforation or obstruction, and the presence of a locally advanced tumor were significant prognostic factors for both overall and cancer-specific survival. Postoperative morbidity rates differed significantly between the locally advanced and non-locally advanced tumor groups (22.7% vs. 12.3%, P < 0.01). No significant overall survival difference was observed among the stage II transverse colon tumors (P = 0.21). CONCLUSION Surgical resection of locally advanced transverse colon tumors resulted in a higher morbidity and mortality than that of non-locally advanced tumors, but the benefit of extensive surgery in the case of locally advanced tumors cannot be underestimated. Furthermore, this benefit is more pronounced in the case of stage II tumors.

Abstract
BACKGROUND AND AIMS The role of carcinoembryonic antigen (CEA) in the early detection of recurrence during the postoperative follow-up of colorectal cancer remains unclear. We hypothesize that the tumor with longer lead time of CEA elevation to the definite recurrence may have a better prognosis because of its slower growth rate and closer observation. MATERIALS AND METHODS From 1995 to 2003, 4,841 consecutive patients who received curative resection of localized colorectal adenocarcinoma were enrolled from a prospective database. The patients with persisting CEA elevation after operation had been already excluded. Postoperative follow-up, including physical examination, imaging, and CEA test, were performed according to a surveillance program. A CEA >/=5 ng/mL was defined as elevated. The definition of the CEA lead time was the period between CEA elevation and detection of recurrence. All statistical analyses were performed by SPSS package for Windows (Microsoft, Redmond, WA, USA). RESULTS The postoperative median follow-up time for the 4,841 patients was 68 months. A total of 999 patients (20.6%) had CEA elevation and recurrence. Among these patients, recurrence was confirmed in 727 patients (72.8%)before, at the same time, or within 3 months of CEA elevation and thus had a short lead time of CEA elevation (SLT group). In 272 patients (27.2%), recurrence was confirmed after more than 3 months of CEA elevation and thus had a longer lead time of CEA elevation (LLT group). The recurrence pattern showed similarities in these two groups. A total of 193 patients (193/999, 19.3%) received a second radical operation, and 806 patients (80.7%) were inoperable. The re-resection rate between the SLT group (146 patients, 20.1%) and the LLT group (47 patients, 17.3%) was not significantly different. The overall survival rate after recurrence showed no difference between these two groups (P = 0.123). CONCLUSION Most cases of recurrence were detected at nearly the same time when the CEA level was elevated. Therefore, a more sensitive test is needed for early detection. The relationship between the lead time of CEA and the clinical outcome was not statistically significant. A more aggressive approach to the patient who has CEA elevation and is highly suspect of recurrence may be needed.

Abstract
BACKGROUND The purpose of this study was to evaluate the clinicopathologic features and prognosis of signet ring cell carcinoma (SCC) and non-SCC mucinous adenocarcinoma (MC) and to compare them with those of nonmucinous adenocarcinoma (NMC) of the colon. METHODS From January 1995 to December 2003, 45 patients with SCC and 332 with MC were identified from prospectively collected medical records. The clinical data and outcomes were compared with those of 2984 consecutive patients with NMC in the same period. RESULTS The mean age at onset of SCC was 54.3 years. This was significantly lower than those for MC (mean 59.5 years, p = 0.038) and NMC (62.4 years, MC vs. NMC, p < 0.01). The rate of spread of tumors in TNM stage IV via hematogenous routes (liver, lung, bone, and brain) was significantly lower in SCC patients (5/28, 17.9%) than in MC (40/104, 38.5%) and in NMC patients (417/694, 60.1%). The rate of tumor spread via lymphatic drainage (systemic node) or seeding to the peritoneum was higher in SCC (23/28, 82.1%) and MC patients (79/104, 76.0%), than in NMC patients (343/694, 49.4%, p < 0.001). There was a higher proportion of poorly differ-entiated tumors in SCC (32/42, 71.1%) than in MC (26/332, 7.8%) and NMC (203/2984, 6.8%). The 1-, 2-, and 5-year overall survival rates of patients with SCC were 77.8%, 26.7%, and 11.9%, of those with MC, 81.6%, 65.9%, and 49.4% and of those with NMC, 84.1%, 73.3%, and 58.7%, respectively. CONCLUSION The prognosis of SCC is poorer than that of MC and NMC. SCC patients had more locally advanced and almost no early-detected tumors, less hematogenic spread, and very poor surgical outcomes. The role of resection for late stage SCC should be carefully evaluated.

Abstract
Familial adenomatous polyposis (FAP) is an autosomal-dominant disease caused by germline mutations in the adenomatous polyposis coli (APC) gene. The affected individuals develop colorectal polyposis and show various extra-colonic manifestations. In this study, we aimed to investigate the genetic and clinical characteristics of FAP in Taiwanese families and analyze the genotype-phenotype correlations. Blood samples were obtained from 66 FAP patients registered in the hereditary colorectal cancer database. Then, germline mutations in the APC genes of these 66 polyposis patients from 47 unrelated FAP families were analyzed. The germline-mutation-negative cases were analyzed by performing multiplex ligation-dependent probe amplification (MLPA) and single-strand conformation polymorphism (SSCP) analysis of the MUTYH gene. Among the analyzed families, 79% (37/47) of the families showed 28 APC mutations, including 19 frameshift mutations, 4 nonsense mutations, 3 genomic deletion mutations, 1 missense mutation, and 1 splice-site mutation. In addition, we identified 15 novel mutations in 32% (15/47) of the families. The cases in which APC mutations were not identified showed significantly lower incidence of profuse polyposis (P = 0.034) and gastroduodenal polyps (P = 0.027). Furthermore, FAP families in which some affected individuals had less than 100 polyps showed significant association with low incidence of APC germline mutations (P = 0.002). We have added the APC germline-mutation data for Taiwanese FAP patients and indicated the presence of an FAP subgroup comprising affected individuals with nonadenomatous polyps or less than 100 adenomatous polyps; this form of FAP is less frequently caused by germline mutations of the APC gene.

Abstract
PURPOSE To compare survival and histologic features of hereditary nonpolyposis colorectal cancer (HNPCC; Lynch syndrome) cases to well-matched sporadic colon cancers from the same patient population. EXPERIMENTAL DESIGN Between January 1995 and March 2002, a total of 5,138 consecutive patients underwent resection of primary colorectal adenocarcinoma in a single institution. According to the Amsterdam criteria, 56 HNPCC patients were matched to 147 sporadic colorectal cancer (SCRC) with no family history of cancer and with the same gender, tumor location, and age within 3 years. Immunohistochemical analyses were done for MUC1, MUC2, MUC3, and MUC5AC. RESULTS The HNPCC group had a marginally significantly better long-term outcome than the SCRC group (P = 0.058). The trend disappeared after adjustment by tumor-node-metastasis stage in a Cox model (P = 0.774). We noted a difference of >50% in the 5-year cancer-specific survival rates of HNPCC- and SCRC-mucinous groups (92% versus 31%, P = 0.0003). Interaction between mucin and HNPCC and its effects on survival were further confirmed by comparing the Cox models with and without interaction terms (hazard ratio, 0.1; P = 0.034 with adjusting stage). Patients with tumors showing dual expression of mucin and MUC1, which appeared in 11% of those with HNPCC and 50% of those with SCRC, had a lower 5-year cancer-specific survival rate than patients without (30% versus 60%; P = 0.004 by log-rank test; P = 0.039 with adjustment for tumor-node-metastasis stage). CONCLUSIONS These results suggest that mucin has an inverse effect on survival in patients with HNPCC and SCRC, which might be partly explained by a lower prevalence of MUC1 expression in the mucinous HNPCC group than in the SCRC groups.

Abstract
PURPOSE Vascular endothelial growth factor and nitric oxide are both related to tumor progression. This study was designed to measure preoperative plasma vascular endothelial growth factor and nitrite levels in patients with colorectal cancer to evaluate their clinical applications as tumor markers. METHODS In total, 279 patients with primary colorectal cancer and 20 patients with hemorrhoids (as a control) were included in this study. Plasma vascular endothelial growth factor was measured by quantitative, solid-phase, enzyme-linked immunosorbent assay (R&D Systems), whereas nitrite was measured by a high-performance liquid chromatographic method. RESULTS The vascular endothelial growth factor (mean, 220.6 pg/ml, P < 0.005) and nitrite (mean, 29.4 microM, P = 0.043) levels of patients with cancer were significantly higher than those of controls (mean vascular endothelial growth factor, 67 pg/ml; mean nitrite, 23 microM). Preoperative plasma vascular endothelial growth factor levels were positively correlated with tumor stage, T class, M class, and tumor size (Spearman correlation, P < 0.01), but were not associated with gender, N class, tumor location, histology type, or grade. There were no statistical differences in nitrite levels among different groups of patients with cancer. Higher vascular endothelial growth factor levels also were correlated with leukocytosis, elevated carcinoembryonic antigen, and a higher platelet count. The positive rates of vascular endothelial growth factor elevation (>148.6 pg/ml) compared with carcinoembryonic antigen elevation were 36.9 to 14.6 percent in Stage I, 60.9 to 33 percent in Stage II, 62.9 to 48.7 percent in Stage III, and 86 to 70.2 percent in Stage IV, respectively. The overall positive rate of vascular endothelial growth factor elevation also was higher than that of carcinoembryonic antigen elevation (63 percent for vascular endothelial growth factor vs. 42.5 percent for carcinoembryonic antigen, P = 0.016). More than one-half of the patients without carcinoembryonic antigen elevation still had elevated vascular endothelial growth factor levels. The combined assessment using vascular endothelial growth factor and carcinoembryonic antigen was superior to individual assessment using vascular endothelial growth factor or carcinoembryonic antigen. In node-negative tumor, the patients with vascular endothelial growth factor elevation had worse disease-free survival than those without vascular endothelial growth factor elevation (P = 0.0367). There was no association of vascular endothelial growth factor elevation with survival in patients with node-positive tumor. CONCLUSIONS Plasma vascular endothelial growth factor is a useful complementary tumor marker; however, synchronous measurement of white blood cells, platelets, and carcinoembryonic antigen is suggested in the clinical application of vascular endothelial growth factor to colorectal cancer.

Abstract
AIMS/HYPOTHESIS The gene encoding solute carrier family 2, facilitated glucose transporter, member 10 (SLC2A10, previously known as glucose transporter 10 [GLUT10]) is a promising candidate gene for type 2 diabetes since it is highly expressed in liver and pancreas and is located on human chromosome region 20q12-q13.1, a region previously shown to harbour type 2 diabetes susceptibility genes. We investigated whether the SLC2A10 gene could be a type 2 diabetes susceptibility gene in the Taiwanese population. SUBJECTS AND METHODS Sequencing of SLC2A10 gene from 48 diabetic subjects detected short tandem repeat polymorphisms in the promoter region, but did not detect any other sequence variants or new single-nucleotide polymorphisms (SNPs) other than those already in the SNPper database ( http://snpper.chip.org ) (30 June 2005). RESULTS Using these genetic polymorphisms, we divided the SLC2A10 gene into four distinct linkage disequilibrium blocks and performed a case-control association study in a group of type 2 diabetes subjects (n = 375) and normoglycaemic individuals (n=377). The HapD (A-G-T-C) haplotype in block 3, a rare haplotype, which consisted of four SNPs (rs3092412, rs2235491, rs2425904 and rs1059217), was modestly associated with type 2 diabetes with a haplotype score of -2.95567 (p = 0.012 with the haplotype-specific test). CONCLUSIONS/INTERPRETATION Our results suggest that SLC2A10 genetic variations do not appear to be major determinants for type 2 diabetes susceptibility in the Taiwanese population.

Abstract
PURPOSE Massive hematochezia from acute hemorrhagic rectal ulcer can arise in patients with severe comorbid illness who are bedridden for long periods. If the bleeder is not found and treated immediately, the bleeding will cause deterioration of health and even threaten life. The results of the current study show how quickly and safely per anal suturing can treat acute hemorrhagic rectal ulcer. METHODS From January 2003 to December 2003, the records of 26 patients who underwent per anal suturing of acute hemorrhagic rectal ulcer were retrospectively reviewed. The identification of acute hemorrhagic rectal ulcer was confirmed by clinical and anoscopic examination. RESULTS Most of these patients were elderly and bedridden (14 men; median age 69 years). Main comorbid illnesses existed in all patients and included liver cirrhosis (8 patients, 31 percent), sepsis (13 patients, 50 percent), cerebral vascular accident (15 patients, 58 percent), respiratory failure (13 patients, 50 percent), and malignancy (7 patients, 27 percent). Effective hemostasis was achieved in all patients by direct suture of bleeding ulcer. No complications developed relative to the per anal suturing procedure among any patients. Although 11 patients developed recurrent hematochezia, 9 patients responded to repeated therapy. The risk factors associated with recurrent bleeding were severity of disease and abnormal coagulation. CONCLUSIONS When massive hematochezia occurs in bedridden patients with severe comorbid illness, it is essential to investigate the lower rectum, which often is affected by acute hemorrhagic rectal ulcer. Recognition of this clinical presentation will result in early identification and therapy. Per anal suturing of a bleeder at the bedside provides a quick, safe, and successful management of acute hemorrhagic rectal ulcer.

Abstract
AIM: To evaluate the diagnostic accuracy, sensitivity, specificity of contrast-enhanced computed tomographic colonography in detecting local recurrence of colorectal cancer.
METHODS: From January 2000 to December 2004, 434 patients after potentially curative resection for invasive colorectal cancer were followed up for a period ranging from 20 to 55 mo. Eighty of the four hundred and thirty-four patients showing strong clinical evidence for recurring colorectal cancer during the last follow-up were enrolled in this study. Each patient underwent contrast-enhanced computed tomographic colonography and colonoscopy on the same day. Any lesions, biopsies, identified during the colonoscopic examination, immediate complications and the duration of the procedure were recorded. The results of contrast-enhanced computed tomographic colonography were evaluated by comparing to those of colonoscopy, surgical finding, and clinical follow-up.
RESULTS: Contrast-enhanced computed tomographic colonography had a sensitivity of 100%, a specificity of 83% and an overall accuracy of 94% in detecting local recurrent colorectal cancer.
CONCLUSION: Conventional colonoscopy and contrast-enhanced tomographic colonography can complement each other in detecting local recurrence of colorectal cancer.

Abstract
Two chemokine (C-X3-C) receptor 1 (CX3CR1) gene polymorphisms, V249I and T280M, and 10 CC chemokine receptor 5 (CCR5) promoter haplotypes, P1-P10, have recently been reported to influence the progression of acquired immune-deficiency syndrome (AIDS). As these studies were performed mainly with Caucasian and African-American subjects, we determined the distribution of these alleles in Chinese people for the purpose of predicting possible clinical responses to the human immunodeficiency virus type 1 (HIV) epidemics in countries with significant Chinese populations, as well as to establish their effects on the expression of surface CCR5. Ninety-six HIV-negative Chinese individuals in Taiwan were subjected to genotyping, and we thus determined that the allelic frequencies of CX3CR1V249I and T280M changes were 2.6% and 2.1%, respectively, which were lower than found in Caucasians (25.5% and 14.0%, respectively). Unlike the previous reports, we only detected CCR5P1 and P4 haplotypes in Taiwanese people, and the P1/P1, P1/P4 and P4/P4 genotype frequencies were 21.0%, 41.1% and 37.9%, respectively. The sequencing data confirmed the results of previous studies, showing that CCR5P1 exhibited a complete linkage disequilibrium with a polymorphic allele 59029A present in the CCR5 promoter. Furthermore, fluorescence-activated cell sorter analysis revealed that, in the absence of the CCR2-64I mutation, individuals carrying CCR5P1 tended to express more surface CCR5 on monocytes and CD4+ cells. Therefore, this study not only reports the frequencies for the CX3CR1 and CCR5 promoter haplotypes in a Chinese population living in Taiwan, but also identifies a statistical link between the P1/P1 haplotype and the elevated CCR5 expression levels in the study group.

Abstract
BACKGROUND AND AIMS Signet ring cell carcinoma of the rectum (SCCR) is a rare type of rectal carcinoma. This study examined the clinical significance of SCCR. PATIENTS AND METHODS From our medical records we retrospectively identified 61 SCCR patients and compared their clinical data and outcomes to those of 144 consecutive patients with non-SCCR mucinous rectal adenocarcinomas (NSMR) and 2,414 consecutive patients with nonmucinous rectal adenocarcinomas (NMR). RESULTS . The incidence of SCCR was 1.39% of rectal cancers. Mean patient age at onset of SCCR (48.1years, range 15-80) was significantly lower than that for NSMR (57.4 years, 9-88) and NMR (62.6 years, 12-94). The proportion of late stage (TNM III+IV) tumors was significantly higher in SCCR (90%) than in NSMR (69%) and NMR (48%). There were more tumors located in the lower rectum in SCCR (46%) than in NSMR (34%) and NMR (29%). SCCR tumors were significantly larger (5.68+/-3.84 cm) than NSMR (4.27+/-1.78 cm) and NMR tumors (3.76+/-1.71 cm). A higher percentage of patients with SCCR (42.6%) received abdominoperineal resection for treatment. In tumors with TNM stage IV the rate of tumor spread via the hematogenous route was significantly lower in SCCR (18.5%) than in NSMR (43.5%) and in NMR (69%). The rate of tumor spread via seeding to the peritoneum was lower in SCCR (22.2%) than in NSMR (43.5%) but higher than in NMR (2.7%). The rate of tumor spread via the lymphatic route was higher in SCCR (44.4%) than in NSMR (26.1%) and significantly higher than in NMR (12.3%). The 1-, 2-, and 5-year overall SCCR survival rates were 73.9%, 36.3%, and 23.3% respectively, which were significantly poorer than those of NSMR and NMR. For the 28 stage III and R0 SCCR tumors the 1-, 2-, and 5-year disease-free survival rates of SCCR were 84.0%, 44.2%, and 30.3%, respectively, which are comparable with general data of stage III rectal cancer in the world. CONCLUSION Diffuse infiltration of signet ring cells enhances the tendency of mucinous carcinomas of the rectum in more local extension and easier lymphatic spreading but not at peritoneal seeding. Although SCCR had the poorest prognosis, this outcome may be due to the advanced tumor stage rather than histology itself.

Abstract
OBJECTIVE To investigate the feasibility of using a ganglial culture system to screen various growth factors as potential therapeutic agents for pelvic nerve injuries. MATERIALS AND METHODS The major pelvic ganglia (MPG) were isolated from male rats and attached to culture dishes with the aid of Matrigel (Becton Dickinson, Mountain View, CA, USA). Alternatively, the dorso-caudal region (DCR) of MPG, from which the cavernous nerves originate, was dissected and then attached to a Matrigel-coated coverslip. The MPG or DCR was cultured in serum-free medium supplemented with phosphate-buffered saline (PBS, control), 50 ng/mL of vascular endothelial growth factor (VEGF), 20 ng/mL of a neurotrophin (BDNF, NT3, or NT4), or combinations of these growth factors. After 2 days of incubation, the ganglial tissues with their outgrowing nerve fibres were stained for the expression of NADPH-diaphorase, tyrosine hydroxylase (TH) and acetylcholinesterase (AChE). The length and staining intensity of nerve fibres were analysed. RESULTS The outgrowing fibres were significantly longer in MPG treated with any of the four tested growth factors than in PBS-treated MPG. The combination of VEGF and NT3 induced the best fibre growth. Improvements to the culturing conditions allowed a histological examination of the outgrowing fibres for the expression of nitric oxide synthase (NOS), TH and AChE. VEGF and BDNF were equally capable of inducing NOS- and TH-expressing fibres. BDNF was much weaker than VEGF for inducing AChE-expressing fibres. CONCLUSIONS This improved culturing system is potentially useful for screening nerve-regenerating factors; VEGF had neurotrophic effects comparable with BDNF, NT3, or NT4.

Abstract
BACKGROUND Preoperative clinical staging of rectal tumors is very important to allow surgeons make informed decisions about the types of surgeries that should be performed. Endorectal ultrasonography (ERUS) is one of the tools that has been commonly used in clinical staging of rectal tumors. The aim of this study was to evaluate the accuracy of the preoperative rectal tumor staging using endorectal ultrasonography in comparison with the postoperative histopathological staging. METHODS The histopathology findings of the 67 patients with rectal tumors who underwent preoperative ERUS were reviewed and compared. RESULTS The overall accuracy of the ERUS assessment in the depth of tumor invasion was 88%, with overstaging at 9% and understaging at 3%. In determining perirectal nodal involvement of the 59 patients that were treated by radical rectal resection, the accuracy was 73%, with sensitivity of 77% and specificity of 70%. CONCLUSION ERUS is an objective, convenient, and highly accurate tool for preoperative rectal tumor staging, thus helping surgeons to determine the appropriate treatment modalities.
