World J Gastrointest Oncol 2024; 16:354-363. [PMID: 38425395 PMCID: PMC10900162 DOI: 10.4251/wjgo.v16.i2.354] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Revised: 11/13/2023] [Accepted: 12/11/2023] [Indexed: 02/02/2024] Open
Abstract
BACKGROUND Colorectal cancer is a common malignant tumor in China, and its incidence in the elderly is increasing annually. Inflammatory bowel disease is a group of chronic non-specific intestinal inflammatory diseases, including ulcerative colitis and Crohn's disease. AIM To assess the effect of screening colonoscopy frequency on colorectal cancer mortality. METHODS We included the clinicopathological and follow-up data of patients with colorectal cancer who underwent laparoscopic colectomy or open colectomy at our Gastrointestinal Department between January 2019 and December 2022. Surgical indicators, oncological indicators, and survival rates were compared between the groups. The results of 104 patients who met the above criteria were extracted from the database (laparoscopic colectomy group = 63, open colectomy group = 41), and there were no statistically significant differences in the baseline data or follow-up time between the two groups. RESULTS Intraoperative blood loss, time to first ambulation, and time to first fluid intake were significantly lower in the laparoscopic colectomy group than in the open colectomy group. The differences in overall mortality, tumor-related mortality, and recurrence rates between the two groups were not statistically significant, and survival analysis showed that the differences in the cumulative overall survival, tumor-related survival, and cumulative recurrence-free rates between the two groups were not statistically significant. CONCLUSION In elderly patients with colorectal cancer, laparoscopic colectomy has better short-term outcomes than open colectomy, and laparoscopic colectomy has superior long-term survival outcomes compared with open colectomy.

Value of different anastomoses in laparoscopic radical right hemicolectomy for right-sided colon cancer: retrospective study and literature review. World J Surg Oncol 2022; 20:318. [PMID: 36171623 PMCID: PMC9520856 DOI: 10.1186/s12957-022-02789-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2022] [Accepted: 09/21/2022] [Indexed: 01/19/2023] Open
Abstract
Background This study aimed to analyze the safety of circular lateral anastomosis and cross-lateral anastomosis in laparoscopic radical resection of right-sided colon cancer. Methods From January 2018 to March 2021, 147 patients with right-sided colon cancer were admitted to the Department of General Surgery, Cancer Hospital, Zhengzhou University. The experimental group comprised patients with circular lateral anastomosis, whereas the control group comprised patients with cruciform lateral anastomosis. The general clinical data, intraoperative features, and postoperative results of the two groups were compared and analyzed. Results Both groups successfully underwent laparoscopic lateral ileocolic anastomosis, with significant differences in anastomotic leakage (χ2=4.520, P < 0.05). By contrast, body mass index (t = 1.568, P = 0.119), histological typing (χ2 = 2.067, P = 0.559), intraoperative bleeding (t = 0.418, P = 0.677), and intestinal obstruction (χ2 = 2.564, P = 0.109) were not significantly different between the groups (P > 0.05). Conclusions In laparoscopic-assisted radical hemicolectomy for right-sided colon cancer, the incidence of postoperative anastomotic leakage was lower with circular lateral anastomosis than with cross-lateral anastomosis, and circular lateral anastomosis was superior to cross-lateral anastomosis in terms of reducing the length of hospital stay and improving patients' postoperative quality of life.

Does the level of inferior mesenteric artery ligation affect short-term and long-term outcomes of patients with sigmoid colon cancer or rectal cancer? A single-center retrospective study. World J Surg Oncol 2022; 20:274. [PMID: 36045369 PMCID: PMC9434919 DOI: 10.1186/s12957-022-02741-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Accepted: 08/22/2022] [Indexed: 11/21/2022] Open
Abstract
Background For sigmoid colon or rectal cancer, a definite consensus regarding the optimal level ligating the inferior mesenteric artery (IMA) has not been reached. We performed this study to determine whether the ligation level significantly affected short-term and long-term outcomes of patients with sigmoid colon or rectal cancer after curative laparoscopic surgery. Methods Medical records of patients with sigmoid colon or rectal cancer who had undergone curative laparoscopic surgery between January 2008 and December 2014 at the Department of Gastrointestinal Surgery, Guangdong Provincial Hospital of Traditional Chinese Medicine were reviewed. Then, the high tie group (HTG) was compared with the low tie group (LTG) in terms of short-term and long-term outcomes. Results Five-hundred ninety patients were included. No significant differences between two groups regarding baseline characteristics existed. HTG had a significantly higher risk of anastomotic fistula than LTG (21/283 vs 11/307, P = 0.040). Additionally, high ligation was proven by multivariate logistic regression analysis to be an independent factor for anastomotic fistula (P = 0.038, OR = 2.232, 95% CI: 1.047–4.758). Furthermore, LT resulted in better preserved urinary function. However, LTG was not significantly different from HTG regarding operative time (P = 0.075), blood transfusion (P = 1.000), estimated blood loss (P = 0.239), 30-day mortality (P = 1.000), ICU stay (P = 0.674), postoperative hospital stay (days) (P = 0.636), bowel obstruction (P = 0.659), ileus (P = 0.637), surgical site infection (SSI) (P = 0.121), number of retrieved lymph nodes (P = 0.501), and number of metastatic lymph nodes (P = 0.131). Subsequently, it was revealed that level of IMA ligation did not significantly influence overall survival (OS) (P = 0.474) and relapse-free survival (RFS) (P = 0.722). Additionally, it was revealed that ligation level did not significantly affect OS (P = 0.460) and RFS (P = 0.979) of patients with stage 1 cancer, which was also observed among patients with stage 2 or stage 3 cancer. Ultimately, ligation level was not an independent predictive factor for either OS or RFS. Conclusions HT resulted in a significantly higher incidence of anastomotic fistula and worse preservation of urinary function. Level of IMA ligation did not significantly affect long-term outcomes of patients with sigmoid colon or rectal cancer after curative laparoscopic surgery.

Abstract
AbstractLow anterior resection syndrome (LARS) comprises a collection of symptoms affecting patients’ defecation after restorative surgery for rectal cancer. The aim of this work was to study the incidence and risk factors for LARS in China. Rectal cancer patients undergoing total mesorectal excision and colorectal anastomosis between May 2012 and January 2015 were identified from a single center. The patients completed the LARS score questionnaire through telephone. The clinical and pathological factors that may influence the occurrence of LARS were analyzed using univariate and multivariate logistic regression analysis. The influence of postoperative recovery time and pelvic dimensions on the occurrence of LARS was also analyzed. This study included 337 patients, at an average age of 61.03 SD11.32. The mean LARS score of the patients was 14.08 (range 0–41). A total of 126 patients (37.4%) developed LARS after surgery, including 63 (18.7%) severe cases. Compared with the scores within the initial 6 postoperative months, the LARS scores of the patients in 6~18 months after the surgery showed significant reductions (p < 0.01). In multivariate analysis, lower locations of anastomosis, pre-surgery radiotherapy, and shorter postoperative recovery time were significant predisposing factors for LARS. A subgroup analysis revealed that patients suffering from LARS over 18 months after surgery were found to have a significantly shorter interspinous distance than those without LARS (p < 0.05). LARS could improve over time after surgery. Lower anastomotic level and pre-surgery radiotherapy are risk factors for LARS.

Abstract
Objective To investigate the relationship between circulating tumor cells (CTCs) and their subpopulations and colorectal cancer (CRC). To explore the application of CTCs’ numbers and positive rates in the diagnosis and treatment of CRC, and to assess the effect of surgery on CTCs numbers and positivity. Methods We identified CTCs using the CanPatrol technique after enrollment. Peripheral blood samples were collected from 74 CRC patients before anti-tumor treatment. CTCs can be divided into the following three phenotypes: epithelial CTCs (E-CTCs) (EpCAM+, Vimentin-), mesenchymal CTCs (M-CTCs) (EpCAM-, Vimentin+), and mixed CTCs (E/M-CTCs) (EpCAM+, Vimentin+). CTCs and the proportion of subtypes were statistically compared with clinicopathological characteristics. Results The positive rate of M-CTCs was significantly higher in patients with tumor size ≥5 cm (85.7% vs 49.1%, P = 0.004) and carcinoembryonic antigen (CEA) >5 ng/mL (83.3% vs 51.0% p = 0.024). Moreover, the T stage (T1 0, T2 33.3%, T3 59.4%, T4 100%, p < 0.0005) and TNM stage (stage I 11.8%, stage II 79.2%, stage III 64.3%, stage IV 100%, p < 0.0005) were correlated with the positive rate of M-CTCs. We also found that the proportion of M-CTCs was correlated with the T stage (p < 0.0005) and TNM stage (p=0.0200), but not with the N stage (p=0.6889). In survival analysis, M-CTCs >1 were found associated with worse disease-free survival (p=0.007). After treatment, the number and proportion of CTCs and M-CTCs were significantly reduced. Conclusion The positive rate of M-CTCs was associated with tumor size, T stage, TNM stage, vascular invasion, and CEA. As the disease progressed, the proportion of M-CTCs gradually increased, and the survival performance was worse in patients with a high positive rate of M-CTCs.

Abstract
Background: Laparoscopic colorectal resection has been gaining popularity over the past two decades-and the number of elderly patients with colorectal cancer treated with a surgical modality has gradually increased. However, studies about laparoscopic rectal surgery in elderly patients with long-term oncologic outcomes are limited. In this study, we evaluated the safety and effectiveness of laparoscopic resection in patients with rectal cancer aged ≥80 y. Methods: From 2007-2015, a total of 84 consecutive patients with rectal cancer from a single institution were included, 45 patients undergoing laparoscopic rectal resection were compared with 39 patients undergoing open rectal resection. Results: The two groups were well balanced in terms of age, gender, body mass index, American society of anesthesiologists scores, previous abdominal surgery, neoadjuvant therapy, tumor stage, distance of tumor from the anal verge, and comorbidities. One (2.2%) patient in the laparoscopic group required conversion to open surgery. Laparoscopic surgery was associated with significantly longer operating time (160.1±28.2 versus 148.2±41.3 min; P=0.031), less intraoperative blood loss (80.5±20.9 versus 160.3±42.4 mL; P=0.002), less need of blood transfusion (6.7% versus 20.5%; P=0.003), a shorter time to diet recovery (2.5±1.5 versus 4.9±1.1; P=0.015) and postoperative hospital stay (7.5±4.5 versus 10.8±4.2; P=0.035), lower overall postoperative complication rate (8.9% versus 20.5%; P=0.017), and wound-related complication rate (4.4% versus 10.2%; P=0.013) when compared with open surgery. Specimen length, no. of retrieced lymph nodes, positive distal and circumferential margin rate, mortality rate, and reoperation rate were not significantly different between two groups. The disease-free and overall 5-year survival rates were similar between two groups. Conclusions: Laparoscopic rectal surgery is safe and feasible in patients aged≥80 y and is associated with similar long-term oncologic outcomes when compared with open surgery.

Abstract
BACKGROUND Transanal total mesorectal excision is a promising surgical procedure for mid to low rectal cancer. OBJECTIVE This study aimed to determine the short-term outcomes of Chinese patients treated with transanal total mesorectal excision. DESIGN This was an observational study using data from an online registry system. SETTING Study participants were recruited from 40 different centers across 15 provinces in China. PATIENTS Patients with either benign or malignant rectal disease who underwent transanal total mesorectal excision procedure and were registered in the Chinese Transanal Total Mesorectal Excision Registry Collaborative from May 2010 to November 2019 were included. INTERVENTION Patients underwent transanal total mesorectal excision. MAIN OUTCOME MEASURES The primary outcomes measured were the postoperative complications and pathological outcomes. RESULTS In total, 1283 patients, comprising 888 men (69.2%) and 395 women (39.8%) with a median age of 61 (22-92) years and a median BMI of 23.6 (14.5-46.3) kg/m2, were analyzed. Among 40 participating centers, the average number of registered cases was 32.1±34.7, and 12 centers (30%) registered >40 cases in the registry. Among 849 patients with rectal cancer who underwent laparoscopic-assisted transanal total mesorectal excision, the conversion rate was 0.5% in the abdominal phase and 1.9% in the perineal phase. Three patients reported urethral injury (0.5%). The postoperative complication rate and the anastomotic leakage incidence were 18.4% and 5.8%. The quality of the total mesorectum excision specimens was found to be complete in 81.9% of patients. In addition, the positive circumferential resection margin rate was 2.8%. LIMITATIONS The primary limitation of this registry study was the high percentage of missing data (10.8% overall), and, for some of the analyzed variables, up to 35% of the data was missing. Postoperative complications were not monitored after discharge, resulting in a lower morbidity rate than the 30-day morbidity rate reported in other studies. CONCLUSIONS The short-term outcomes of patients who underwent transanal total mesorectal excision procedures in China were acceptable. See Video Abstract at http://links.lww.com/DCR/B414. EXCISIN TOTAL DEL MESORRECTO POR VA TRANSANAL RESULTADOS A CORTO PLAZO DE CASOS DE UN REGISTRO NACIONAL EN CHINA ANTECEDENTES:La excisión total del mesorrecto por vía transanal es un procedimiento quirúrgico prometedor para el cáncer de recto medio y bajo.OBJETIVO:Determinar los resultados a corto plazo de los pacientes chinos tratados con escisión mesorrectal total transanal.DISEÑO:Estudio observacional con datos de un sistema de registro en línea.AJUSTE:Los participantes del estudio fueron reclutados en 40 centros diferentes en 15 provincias de China.PACIENTES:Se incluyeron pacientes con enfermedad rectal benigna o maligna que se sometieron a una cirugía de excisión total del mesorrecto por vía transanal y que se registraron en el Registro Colaborativo de Excisión Total del Mesorrecto por vía Transanal en China desde mayo de 2010 hasta noviembre de 2019.INTERVENCIÓN:Excisión total delmesorrecto por vía transanal.PRINCIPALES MEDIDAS DE RESULTADO:Complicaciones postoperatorias y resultados patológicos.RESULTADOS:Fueron analizados un total de 1.283 pacientes, que comprendían 888 hombres (69,2%) y 395 mujeres (39,8%) con una mediana de edad de 61 (22-92) años y una mediana de índice de masa corporal de 23,6 (14,5-46,3) kg / m2. Entre los 40 centros participantes, el promedio de casos registrados fue de 32,1 ± 34,7, y 12 centros (30%) inscribieron > 40 casos en el registro. Entre 849 pacientes con cáncer de recto que se sometieron a excisión total del mesorrecto pééor vía transanal asistida por laparoscopia, la tasa de conversión fue del 0,5% en la fase abdominal y del 1,9% en la fase perineal. Tres pacientes refirieron una lesión uretral (0,5%). La tasa de complicaciones posoperatorias y la incidencia de fuga anastomótica fueron del 18,4% y el 5,8%, respectivamente. La calidad de las muestras de excisión total del mesorrecto se evaluó como completa en el 81,9% de los pacientes. Además, la tasa de margen de resección circunferencial positiva fue del 2,8%.LIMITACIONES:La principal limitación del presente estudio de registros fue el alto porcentaje de datos faltantes (10,8% en general), y para algunas de las variables analizadas, faltaba hasta el 35% de los datos. Las complicaciones postoperatorias no fueron verificadas después del alta, lo que resultó en una tasa de morbilidad más baja que la tasa de morbilidad a 30 días informada en otros estudios.CONCLUSIONES:Los resultados a corto plazo de los pacientes que se sometieron al procedimiento de excisión total del mesorrecto por vía transanal en China fueron aceptables.

Abstract
BACKGROUND This study aimed to investigate the association between enhanced recovery after surgery (ERAS) nursing program and stoma-related complications (SRCs) and prognosis in patients with low rectal cancer (LRC) undergoing abdominoperineal resection with sigmoidostomy. METHODS LRC patients who underwent elective abdominoperineal resection with sigmoidostomy between May 2016 and May 2019 were retrospectively enrolled. The occurrence of early major or minor SRCs (within postoperative 30 days) was set as the primary end-point. Clinicopathological variables and laboratory tests were compared between patients with or without SRCs. The univariate and multivariate logistic regression analyses were performed to investigate risk factors for SRCs. Hospitalization satisfaction-related and prognosis-related variables were compared between LRC patients with or without ERAS nursing program. RESULTS A total of 288 patients were enrolled and the incidence of SRCs was 26.7% (77/288). ERAS nursing program was the only independent risk factor for SRCs in LRC patients (OR 2.04, 95%CI 1.31-3.12, P = 0.016) by the multivariate logistic regression analysis. Moreover, ERAS nursing program was associated with higher hospitalization satisfaction rate, faster bowel function recovery, better psychological status, and higher quality of life. CONCLUSIONS ERAS nursing program was a protective factor for SRCs and associated with improved prognosis in LRC patients undergoing elective abdominoperineal resection with sigmoidostomy.

OBJECTIVE The S0226 trial demonstrated that the combination of half-dose fulvestrant (FUL) and anastrozole (ANA) (F&A) caused a significant improvement in overall survival (OS) versus ANA monotherapy for first-line treatment of postmenopausal women with hormone receptor-positive metastatic breast cancer (PMW-MBC (HR+)). The objective of this study was to evaluate the cost-effectiveness of F&A in the first-line treatment for PMW-MBC (HR+) in China. DESIGN We constructed a Markov model over a life-time horizon. The clinical outcomes and utility data were obtained from published literature. Cost data were obtained from official Chinese websites. Sensitivity analyses were performed to test result uncertainty. SETTING Chinese healthcare system perspective. POPULATION A hypothetical cohort of adult patients presenting with PMW-MBC (HR+). INTERVENTIONS F&A compared with full-dose FUL and ANAmonotherapy. MAIN OUTCOME MEASURES The main outcome of this study was the incremental cost-effectiveness ratio (ICER) and quality-adjusted life-years (QALY). RESULTS ANA was estimated to have the lowest cost and minimum life-years. The ICER of F&A versus ANA was US$15 665.891/QALY with incremental cost and QALY of US$12 401.120 and 0.792, respectively, which was less than the willingness-to-pay of US$29 383/QALY. Compared with F&A, FUL yielded a higher cost and a shorter lifetime; hence, it was identified as a dominated strategy. The univariate sensitivity analysis indicated the price of FUL was the most influential factor in our study. The probability that F&A was cost-effective at a threshold of US$29 383/QALY in China was 86.5%. CONCLUSION F&A is a cost-effective alternative to FUL and ANA monotherapy for the first-line treatment of PMW-MBC (HR+) in China. F&A is a promising first-line treatment for PMW-MBC (HR+), and more research is needed to evaluate the economy of using F&A in other countries.

Surgical treatment of massive stoma site tumors after a curative operation for rectal cancer. Eur J Surg Oncol 2020; 46:e40-e46. [PMID: 32843278 DOI: 10.1016/j.ejso.2020.07.014] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2020] [Revised: 06/27/2020] [Accepted: 07/10/2020] [Indexed: 11/24/2022] Open
Abstract
OBJECTIVE This study aimed to evaluate the clinical and oncological outcomes of selected rectal cancer patients with massive stoma site tumors who underwent radical resection and reconstruction. METHODS We reviewed 8 cases of massive stoma site tumors in patients who had permanent gastrointestinal stoma in the abdominal wall following radical resection of rectal cancer between March 2013 and May 2018 at the Peking University Cancer Hospital and Peking University Shougang Hospital. RESULTS There were seven males and one female patient, with a median age of 50.6 years. The average time between the initial surgery and the development of a malignant tumor at the stoma site was 5 years (range, 0.5-14 years). The average diameter of the stoma site tumors was 8.1 cm, and the diameter of the largest tumor was 12 cm. After tumor resection, the area of the largest abdominal wall defect was about 15 × 14 cm2. Abdominal wall repair included the use of a tensor fasciae latae muscle flap, local fasciocutaneous rotational flap, and pedicled anterolateral thigh flap. No patient died in the 30 days following surgery. The longest follow-up period was 81 months, and 5 patients died. CONCLUSIONS Multidisciplinary clinical management fosters positive outcomes in treating massive stoma site tumors. Local R0 resection and abdominal wall reconstruction are safe and feasible, and function to removes local disease, allowing patients to live a higher quality of life.

Robotic- vs laparoscopic-assisted proctectomy for locally advanced rectal cancer based on propensity score matching: Short-term outcomes at a colorectal center in China. World J Gastrointest Oncol 2020; 12:424-434.

Abstract
BACKGROUND Reports in the field of robotic surgery for rectal cancer are increasing year by year. However, most of these studies enroll patients at a relatively early stage and have small sample sizes. In fact, studies only on patients with locally advanced rectal cancer (LARC) and with relatively large sample sizes are lacking.
AIM To investigate whether the short-term outcomes differed between robotic-assisted proctectomy (RAP) and laparoscopic-assisted proctectomy (LAP) for LARC.
METHODS The clinicopathological data of patients with LARC who underwent robotic- or laparoscopic-assisted radical surgery between January 2015 and October 2019 were collected retrospectively. To reduce patient selection bias, we used the clinical baseline characteristics of the two groups of patients as covariates for propensity-score matching (PSM) analysis. Short-term outcomes were compared between the two groups.
RESULTS The clinical features were well matched in the PSM cohort. Compared with the LAP group, the RAP group had less intraoperative blood loss, lower volume of pelvic cavity drainage, less time to remove the pelvic drainage tube and urinary catheter, longer distal resection margin and lower rates of conversion (P < 0.05). However, the time to recover bowel function, the harvested lymph nodes, the postoperative length of hospital stay, and the rate of unplanned readmission within 30 days postoperatively showed no difference between the two groups (P > 0.05). The rates of total complications and all individual complications were similar between the RAP and LAP groups (P > 0.05).
CONCLUSION This retrospective study indicated that RAP is a safe and feasible method for LARC with better short-term outcomes than LAP, but we have to admit that the clinically significant of part of indicators are relatively small in the practical situation.

Abstract
The purpose of this research was to examine the effects of continuous care model of information-based hospital-family integration on colostomy patients. Miles' operation is a major operative method for treating low rectal cancer, and this operation results in a permanent colostomy. It is difficult for patients to adapt to their colostomy. Previous studies have applied generally conventional nursing models to colostomy patients. This was a single-blind randomized controlled trial study. The sample of 155 patients who met the inclusion criteria was randomly assigned to either the experimental (n = 81) or control group (n = 74). The control group was provided with a routine standard of care. The experimental group was provided with an experimental treatment that consisted of an information-based (WeChat, blog, QQ, telephone, etc.) hospital-family integration continuous care model. Study variables were collected and instruments were selected as follows: basic information, State-Trait Anxiety Inventory (STAI), a self-efficacy scale, a colostomy complication assessment table, a quality of life scale, and a table of the degree of satisfaction. No statistically significant differences were found in demographic information between the experimental and control groups. In comparison with the control group, subjects in the experimental group had less anxiety and could better cope with anxiety, had a better self-efficacy and quality of life scores, and had fewer complications. The patients in the experimental group were shown to be more satisfied with the care model. In addition, the most useful and popular service is the online social tools WeChat and QQ, because they can communicate with video, and they are more real-time, efficient, and cheap. The continuous care model of information-based hospital-family integration significantly strengthened patients' self-efficacy and confidence, which decreased colostomy complications, ultimately improving the quality of life.

Abstract
BACKGROUND Synchronous colorectal carcinoma (CRC) is a specific and rare type of colorectal malignancy. The data on the impact of synchronous CRC are controversial. This study aimed to compare the characteristics and prognosis between synchronous CRC and solitary CRC. PATIENTS AND METHODS 252 patients who underwent surgery between October 2009 and June 2013 with synchronous CRC (n = 126) or solitary CRC (n = 126) were included. The patients were matched according to age, sex, American Society of Anesthesiologists score, BMI, cancer grade, tumor location, and tumor stage. The short-term outcomes included the length of hospital stay, complications, and 30-day mortality. Long-term endpoints were overall survival (OS), disease-free survival (DFS), and cancer-specific survival (CSS). RESULTS The median follow-up duration for all patients were 42.5 months. The incidence of synchronous CRC was high than in older and male patients as well as in mucinous adenocarcinoma containing signet-ring cell carcinoma, tumor deposit, and polypus. The length of hospital stay after surgery was longer for synchronous CRC than solitary CRC (median: 10 vs. 4 days, P = 0.033). In multivariate analysis, synchronous CRC was an independent prognostic factor associated with poor OS (hazard ratio: 2.355, 95% confidence interval: 1.322-4.195, P = 0.004), DFS (hazard ratio: 2.079, 95% confidence interval: 1.261-3.429, P = 0.004), and CSS (hazard ratio: 2.429, 95% confidence interval: 1.313-4.493, P = 0.005). CONCLUSION The clinical and pathological features exhibit differences between synchronous CRC and solitary CRC and the prognosis of patients with synchronous CRC was poorer than those with solitary CRC.

Abstract
CYP24A1, an essential gene in regulation of vitamin D, has been reported to play an important role in enhancing immune activity and inhibiting tumorigenesis. Previous studies proposed that rs2585428, rs4809960, rs6022999 and rs6068816 in CYP24A1 gene might be greatly associated with cancer risk. To validate the findings, we here investigated the associations of these four polymorphisms and colorectal cancer (CRC) risk in a central Chinese population (426 colon cancer patients, 361 rectal cancer patients and 800 healthy controls). The genotyping was conducted by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and confirmed by sequencing. Our results revealed that the rs4809960 and rs6022999 were strongly associated with the CRC risk, especially with the colon cancer risk. Moreover, the analysis of haplotypes consisting of rs2585428(G > A), rs4809960(T > C), rs6022999(A > G) and rs6068816(C > T) indicated that haplotype ATGC significantly decreased the CRC risk, especially the colon cancer risk. Haplotype GCAT significantly increased the CRC risk, especially the rectal cancer risk. However, haplotype ACAC was only found to be associated with increased risk of CRC. To improve the statistical strength, an updated meta-analysis was further performed. The results showed that rs2585428 was associated with cancer risk in Caucasian population, rs4809960 was associated with breast cancer risk in Caucasian population, and rs6022999 was associated with cancer risk in Asian population. Collectively, the rs4809960 and rs6022999 may be the genetic biomarkers for prediction of colon cancer risk in Chinese population, the rs2585428 and rs6022999 may link to cancer susceptibility in Caucasian population and in Asian population respectly.

Effects of Permissive Hypercapnia on Laparoscopic Surgery for Rectal Carcinoma. Gastroenterol Res Pract 2019; 2019:3903451. [PMID: 31687013 PMCID: PMC6800955 DOI: 10.1155/2019/3903451] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2018] [Revised: 01/14/2019] [Accepted: 08/25/2019] [Indexed: 12/29/2022] Open
Abstract
Background Permissive hypercapnia has been recommended during the treatment of chronic diseases; however, there are insufficient clinical data to investigate the feasibility of permissive hypercapnia in relatively long-term surgeries such as laparoscopic surgery for rectal carcinoma. This prospective study is aimed at investigating the efficacy and safety of permissive hypercapnia under different CO2 pneumoperitoneum pressures during the laparoscopic surgery for rectal carcinoma. Methods A total of 90 patients undergoing laparoscopic surgery for rectal carcinoma were recruited from July 2016 to March 2017. They were randomly assigned to high hypercapnia group (n = 30), low hypercapnia group (n = 30), or control group (n = 30), whose PaCO2 levels were maintained at 56-65 mmHg, 46-55 mmHg, or 35-45 mmHg, respectively. The primary endpoint was peak pressure. Plateau pressure, dynamic compliance, arterial blood analysis, and hemodynamic measures were collected as secondary outcomes. Adverse events were monitored. Results High hypercapnia group were reported to be associated with significantly lower peak pressure and plateau pressure, but higher dynamic compliance compared to low hypercapnia and control group (all P < 0.01). Moreover, patients in the high hypercapnia group had higher postoperation oxygenation index values compared to those in the low hypercapnia and control group (all P < 0.01). There is no significant difference in the pH, Spo2, MAP, heart rate, and adverse events among the three groups. Conclusion Permissive hypercapnia with a PaCO2 level of 56-65 mmHg was able to improve respiratory function after laparoscopic surgery in rectal cancer patients.

Abstract
AIM The need or otherwise for lateral pelvic node dissection (LPND) in rectal cancer patients with clinical lateral pelvic node metastasis (LPNM) after neoadjuvant chemoradiotherapy (nCRT) is controversial. This study was designed to explore the predictive factors for pathological LPNM in rectal cancer patients with clinical LPNM after nCRT. METHOD From January 2010 to February 2018, a consecutive series of patients with rectal cancer and clinical LPNM after nCRT who underwent total mesorectal excision and LPND were reviewed. Patient demographics, operative and pathological outcomes were collected and analysed. RESULTS A total of 76 consecutive cases were included in this study: 53 (69.7%) patients underwent unilateral LPND and 23 (30.3%) bilateral LPND. The pathological results showed that LPNM was found in 13 (17.1%) patients. Multivariate logistic regression analysis showed that the post-nCRT lateral pelvic node size ≥ 5 mm (OR = 7.67, 95% CI = 1.45-40.63, P = 0.017) and mucinous/signet-ring adenocarcinoma (OR = 4.60, 95% CI = 1.11-19.08, P = 0.035) were independent risk factors for pathological LPNM. CONCLUSION Post-nCRT lateral pelvic node size ≥ 5 mm and mucinous/signet-ring adenocarcinoma were independent predictive factors of pathological LPNM for rectal cancer patients with clinical LPNM after nCRT, and patients with these characteristics may benefit from LPND.

Abstract
Background: Conventional methods for predicting treatment response to neoadjuvant chemoradiotherapy (nCRT) in patients with locally advanced rectal cancer (LARC) are limited. Methods: This study retrospectively recruited 134 LARC patients who underwent standard nCRT followed by total mesorectal excision surgery in our institution. Based on pre-operative axial T2-weighted images, machine learning radiomics was performed. A receiver operating characteristic (ROC) curve was performed to test the efficiencies of the predictive model. Results: Among the 134 patients, 32 (23.9%) achieved pathological complete response (pCR), 69 (51.5%) achieved a good response, and 91 (67.9%) achieved down-staging. For prediction of pCR, good-response, and down-staging, the predictive model demonstrated high classification efficiencies, with an AUC value of 0.91 (95% CI: 0.83–0.98), 0.90 (95% CI: 0.83–0.97), and 0.93 (95% CI: 0.87–0.98), respectively. Conclusion: Our machine learning radiomics model showed promise for predicting response to nCRT in patients with LARC. Our predictive model based on the commonly used T2-weighted images on pelvic Magnetic Resonance Imaging (MRI) scans has the potential to be adapted in clinical practice. Novelty and Impact Statements: Methods for predicting the response of the locally advanced rectal cancer (LARC, T3-4, or N+) to neoadjuvant chemoradiotherapy (nCRT) is lacking. In the present study, we developed a new machine learning radiomics method based on T2-weighted images. As a non-invasive tool, this method facilitates prediction performance effectively. It achieves a satisfactory overall diagnostic accuracy for predicting of pCR, good response, and down-staging show an AUC of 0.908, 0.902, and 0.930 in LARC patients, respectively.

OBJECTIVES The aim of the study was to investigate the direct inpatient cost and analyse influencing factors for patients with rectal cancer with low anterior resection in Beijing, China. DESIGN A retrospective observational study. SETTING The study was conducted at a three-tertiary oncology institution. PARTICIPANTS A total of 448 patients who underwent low anterior resection and were diagnosed with rectal cancer from January 2015 to December 2016 at Peking University Cancer Hospital were retrospectively identified. Demographic, clinical and cost data were determined. RESULTS The median inpatient cost was¥89 064, with a wide range (¥46 711-¥191 329) due to considerable differences in consumables. The material cost accounted for 52.19% and was the highest among all the cost components. Colostomy (OR 4.17; 95% CI 1.79 to 9.71), complications of hypertension (OR 5.30; 95% CI 1.94 to 14.42) and combined with other tumours (OR 2.92; 95% CI 1.12 to 7.60) were risk factors for higher cost, while clinical pathway (OR 0.10; 95% CI 0.03 to 0.35), real-time settlement (OR 0.26; 95% CI 0.10 to 0.68) and combined with cardiovascular disease (OR 0.09; 95% CI 0.02 to 0.52) were protective determinants. CONCLUSIONS This approach is an effective way to relieve the economic burden of patients with cancer by promoting the clinical pathway, optimising the payment scheme and controlling the complication. Further research focused on the full-cost investigation in different stages of rectal cancer based on a longitudinal design is necessary.

Abstract
BACKGROUND The addition of ribociclib (RIB) to letrozole (LET) significantly increases progression free survival for patients with hormone-receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced breast cancer (ABC). We identified the range of drug costs for which RIB could be considered cost effective from a Chinese perspective. METHODS A discrete event simulation model was developed to model the treatment sequences among patients with ABC. Life years (LYs), quality-adjusted LYs (QALYs) and lifetime costs were estimated. Costs were estimated for Chinese health care systems. Three times the per capita gross domestic product (GDP) of China 2016 ($24,360) and three times the per capita GDP of Beijing city 2016 ($53,384) were used as the willingness-to-pay threshold. Probabilistic sensitivity analyses were performed. RESULTS In the base case analysis, RIB + LET provided an incremental survival benefit of 0.631 LYs and 0.451 QALYs. When RIB costs less than $721 or $1170 per 4 weeks, there was a nearly 90% likelihood that the incremental cost-effectiveness ratio for RIB + LET would be less than $24,360 per QALY or $53,384 per QALY, respectively. CONCLUSION A value-based price for the cost of RIB is $732 or $1170 per 4 weeks for China and Beijing City, respectively. Our study is helpful to inform the multilateral drug price negotiations in China that may be upcoming for RIB.

Abstract
Early-onset colorectal cancer (EOCRC) is defined as colorectal cancer (CRC) diagnosed before the age of 50. Alarmingly, there has been a significant increase in EOCRC diagnoses' worldwide over the past several decades. Emerging data suggest EOCRCs have distinguishing clinical, pathological, biological and molecular features; and thus, are a fundamentally different subtype of CRCs. Unfortunately, there is no simple explanation for the causes of EOCRC. Scientifically rigorous studies are needed to determine what may be driving the challenging epidemiology of EOCRC. We contend here that a reasonable hypothesis is that prenatal risk factors such as maternal stress and associated sleeping disorders influence offspring epigenetic make-up, and shape immune system and gut health contributing to an increased risk for EOCRC.

Abstract
An increasing proportion of patients aged more than 70 years old are suffering from colorectal cancers. This study aimed to compare the short- and long-terms outcomes between open surgery (OS) or conventional laparoscopic surgery (LS) and hand-assisted laparoscopic surgery (HALS) in treatment of these elderly patients with right colon cancers.We retrospectively reviewed patients who underwent right colon resections for cancers in our institution between June, 2009 and December, 2014. Short- and long-terms outcomes including surgical endpoints, postsurgical recovery data, postoperative morbidity and mortality, overall survival and disease-free survival were compared among OS, LS, and HALS groups. All data were analyzed by SPSS 22.0.Finally, 69 consecutive patients (OS = 26, LS = 24, HALS = 19) with right colon cancers were included in the analysis. Compared with OS, HALS was associated with less time to first anus exhaust (P = .013), first liquid diet (P = .045), and first soft diet (P = .036). Meanwhile, there were significant less operative time (P = .0027), blood loss (P < .001), and less time to first liquid diet (P = .009) in HALS, compared with LS. In regards to long-term outcomes, there were no significant differences in overall survival and disease-free survival among the 3 groups.Compared with OS or LS, HALS may be more favorable in the treatment of elderly right colon cancers with decreased surgical time and postoperative recovery, and comparable cancer-specific survivals.

Abstract
BACKGROUND Patients with liver cirrhosis represent a high risk group for colorectal surgery. The safety and effectiveness of laparoscopy in colorectal surgery for cirrhotic patients is not clear. The aim of this study was to compare the outcomes of laparoscopic colorectal surgery with those of open procedure for colorectal cancer in patients with liver cirrhosis. MATERIALS AND METHODS A total of 62 patients with cirrhosis who underwent radical resections for colorectal cancer from 2005 to 2014 were identified retrospectively from a prospective database according to the technique adopted (laparoscopic or open). Short- and long-term outcomes were compared between the two groups. RESULTS Comparison of laparoscopic group and open group revealed no significant differences at baseline. In the laparoscopic group, the laparoscopic surgery was associated with reduced estimated blood loss (136 vs. 266 ml, p = 0.015), faster first flatus (3 vs. 4 days, p = 0.002) and shorter days to first oral intake (4 vs. 5 days, p = 0.033), but similar operative times (p = 0.856), number of retrieved lymph nodes (p = 0.400) or postoperative hospital stays (p = 0.170). Despite the similar incidence of overall complications between the two groups (50.0% vs. 68.8%, p = 0.133), we observed lower morbidities in laparoscopic group in terms of the rate of Grade II complication (20.0% vs. 50.0%, p = 0.014). Long-term of overall and Disease-free survival rates did not differ between the two groups. CONCLUSION Laparoscopic colorectal surgery appears to be a safe and less invasive alternative to open surgery in some elective cirrhotic patients in terms of less blood loss or early recovery and does not result in additional harm in terms of the postoperative complications or long-term oncological outcomes.

Abstract
BACKGROUND DATA Currently, data regarding the rates of morbidity and mortality following non-elective colectomy for ulcerative colitis (UC) are variable. We sought to determine the rates and predictors of 90-day mortality and complications following colectomy for UC. METHODS Patients undergoing an initial surgery for UC at a tertiary care center between January 2002 and January 2014 were included. Patients were identified using ICD-9 code 556.x. Each record was manually reviewed for demographic information, medical histories, UC history, medications, and data regarding the admission and discharge. Charts were reviewed for mortality and complications within 90 days of surgery. Complications were classified using the Clavien-Dindo classification system. Univariate and multivariate analyses were performed using IBM SPSS Statistics, version 23.0. RESULTS Two hundred and fifty-eight patients underwent surgery for UC. 69% were elective, and 31% were urgent/emergent. There were no deaths reported within 30 days of surgery. At 90 days, there were 2 deaths in the elective group and 1 death in the urgent/emergent group. The death in the urgent/emergent group was likely related to the initial surgery, while the elective group death was not directly related to the initial surgery for UC. Complications occurred in 47% of patients. There were no significant differences in rates of complications in either surgical cohort. Majority (62%) of the complications were Clavien-Dindo grade 1 or 2 with no difference in the elective or urgent/emergent group. Unplanned readmissions occurred in 24% of cases. CONCLUSION Surgery for UC is not associated with any mortality at 30 days and very low mortality at 90 days. However, surgery is associated with an increased rate of minor postoperative complications and readmissions.

Abstract
OBJECTIVE The aim of this study is to explore the safety and function of extraperitoneal sigmoidostomy for patients with rectal cancer who underwent abdominoperineal resection. METHODS We systematically reviewed records of patients with rectal cancer who underwent abdominoperineal resection and extraperitoneal or intraperitoneal sigmoidostomy from January 2010 to December 2014 at our department. They were grouped into the extraperitoneal (group A) and intraperitoneal sigmoidostomy (group B) groups. Clinical data were collected and statistically analyzed. RESULTS A total of 231 consecutive cases were included: 108 cases in group A and 123 in group B. Patient demographics were similar in both groups. Group A was associated with less time for sigmoidostomy (19.6 ± 2.8 vs. 27.0 ± 4.5 min, p < 0.001), shorter postoperative hospitalization (6.4 ± 1.3 vs. 6.9 ± 1.6 days, p = 0.036), less incidence of stoma-related complications (p = 0.002) and less possibility of re-operation related to stomal complications (p = 0.037). Functions of stoma including stimulation of excrement, stimulating time for excrement, frequency of excrement, self-controlled ability of excrement, and regularity of excrement were all better than those in group B patients (p < 0.001, < 0.001, 0.018, 0.004, and 0.001, respectively). Patients in group A had less psychological problems including anxiety (p = 0.008), depression (p = 0.045), and impaired social interaction (p = 0.010). CONCLUSIONS Extraperitoneal sigmoidostomy is associated with shorter operative duration and postoperative hospitalization and has fewer complications and better outcome for abdominoperineal resection of rectal cancer, and patients also had less psychological problems.

Abstract
OPINION STATEMENT Colorectal cancer (CRC) is the third most common cancer worldwide. CRC has been thought to be less common in Asia compared to Western countries. However, the incidence rates of CRC in Asia are high and there is an increasing trend in the Asian population. Furthermore, colorectal cancer accounts for the greatest number of all incidences of CRC in Asia. The increasing adoption of a Western lifestyle, particularly in dietary habits, is likely the most important factor contributing to the rapid increase in colon cancer incidence; it is noteworthy that trends for rectal cancer were flat. The etiology of colon and rectal cancer is a bit different. The risks of distal colon and rectal cancers are more likely to be related to environmental factors, such as polluted surface water sources, alcohol consumption, and habitual smoking. The lack of great change in the incidence of rectal cancer might be due to weaker associations with such lifestyle factors. Therefore, it has been hypothesized that proximal and distal sections of the colon and rectum are two different organs in terms of function and genetic background. It may mean differences in differential sensitivities and exposures to carcinogens. However, despite the decrease in whole incidence, the CRC incidence in young adults in Western countries are reversely increasing, especially in rectal cancer, due to reasons largely unknown. Although the treatment algorithm is different between Asia and western countries, globally, the survival rate for patients with rectal cancer has risen during the past 10 years. Screening contributes a great deal to reducing the incidence and improving survival. Most countries in Asia, such as China, need nationwide registration and screening systems to provide better data.

Abstract
WHAT IS KNOWN AND OBJECTIVE Research has indicated that some Chinese herb injections (CHIs) might be beneficial in combination with chemotherapy, including remedies that might be used as effective chemosensitizers and radiosensitizers, or as palliative therapy. Here, we carried out a network meta-analysis to assess the clinical efficacy and safety of CHIs combined with oxaliplatin, 5-fluorouracil and leucovorin (FOLFOX) for advanced colorectal cancer (CRC). METHODS PubMed, EMBASE.com, the Cochrane Central Register of Controlled Trials (CENTRAL), Chinese Biomedical Literature Database (CBM), Wanfang Database and Chinese Journal Full-text Database were searched from inception to 31 December 2014, to identify relevant randomized controlled trails (RCTs). The risk of bias in included RCTs was evaluated according to the Cochrane Handbook version 5.1.0. Standard pairwise meta-analysis and Bayesian network meta-analysis were performed to compare the efficacy and safety of different CHIs combined with FOLFOX. Data were analysed using STATA 12.0 and WinBUGS1.4 software. RESULTS AND DISCUSSION We identified 63 eligible studies (with 4837 patients in total), involving 9 CHIs. Pairwise meta-analysis showed that compared with FOLFOX alone, combinations with Aidi injection and compound matrine injection could significantly improve the overall response rate and quality of life and reduce the incidence of nausea and vomiting (III-IV), diarrhoea (III-IV), thrombocytopenia (III-IV), leukopenia (III-IV) and peripheral neurotoxicity (III-IV). According to results of indirect comparison, there were no statistically significant differences for most of comparison groups. Aidi+FOLFOX, shenqifuzheng+FOLFOX and compound matrine+FOLFOX had the greatest probability of being the best treatment in clinical efficacy and safety, considering the small sample size. WHAT IS NEW AND CONCLUSIONS Most of the included studies were of low quality, and there was a scarcity of eligible trials and numbers of participants. Based on currently limited evidence, aidi, shenqifuzheng and compound matrine were superior to other CHIs in patients receiving FOLFOX chemotherapy for advanced CRC. More studies are required to confirm the efficacy of CHIs in combination with FOLFOX for advanced CRC.

Abstract
Low anterior resection (LAR) with total mesorectal excision has been considered a standard treatment for patients with rectal cancer. However, the functional outcome and life quality of laparoscopic LAR (LLAR) in Chinese patients remain unclear. A cohort of 51 Chinese patients (22 men and 29 women) who had undergone LLAR was included in this study. Anorectal manometry combined with the Wexner scores questionnaire were applied to assess functional outcome preoperatively (1 week) and postoperatively (at 3, 6 and 9 months). The validated Chinese versions of the European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-CR38 questionnaires were also used to assess the patients' quality of life at the indicated time points. The results demonstrated that the manometric parameters exhibited a temporary decrease at 3 months postoperatively, but a gradual increase at 6 and 9 months, while the Wexner scores exhibited an opposite trend. Furthermore, patients with high anastomoses had significantly higher manometric parameters, a lower frequency of incontinence and lower Wexner scores compared with those with low anastomoses at 9 months (all P<0.05). For the entire cohort, quality of life at 3 months postoperatively was worse compared with the preoperative level, but returned to normal by 9 months. Patients with high anastomoses exhibited significantly better role, emotional and social function, had a better body image and sexual function, fewer problems with defecation and lower frequency of diarrhea, as well as fewer chemotherapy-related side effects at 6 months postoperatively when compared with the low anastomosis group (all P<0.05). In conclusion, LLAR is generally acceptable for Chinese patients with rectal cancer, particularly for those with middle or high rectal cancer, in terms of functional outcome and quality of life.

METHOD A total of 74 consecutive schistosomal colorectal cancer patients who underwent curative surgery from July 2009 to July 2012 were included in this study. The clinical and pathological characteristics of all 74 patients were analysed and univariate and multivariate analyses were performed. This study demonstrated positive correlations between the site of deposition of schistosomal eggs and certain essential variables. RESULTS Depositional site of schistosome eggs, carcinoembryonic antigen (CEA) level and the pathological N and T stages were statistically significantly correlated with overall survival (OS). The pathological T stage and the CEA level were independent prognostic factors for OS. The site of deposition of schistosome eggs was positively correlated with the T and N stages, tumour size, the CEA level and the resection margins. CONCLUSIONS Schistosome eggs might be associated with tumorigenesis. The site of deposition of schistosome eggs was statistically significantly correlated with OS but it was not an independent prognostic factor for OS. It was, however, correlated with the depth of the tumour. The presence of schistosoma eggs at the margin did not affect the patient's prognosis or anastomotic healing. The existing standard surgical approach was equally applicable to schistosomal colorectal cancer. It was not necessary to expand the scope of surgical resection.

Abstract
Colorectal cancer is the third most common cancer and the fourth most common cause of cancer-related death globally. This population-based study aimed to explore the predictive factors that affected the overall survival of rectal cancer patients receiving adjuvant chemotherapy plus radical surgery using a Cox proportional hazards modeling approach. A total of 619 patients with rectal cancer who underwent surgery were enrolled between October 2006 and May 2013. Clinical characteristics of the patients were compared among the groups and potential prognostic factors were analyzed using the spss program, version 19.0. Patients aged ≥ 70 years have distinctive characteristics such as lager tumour size (≥ 5 cm), damaged micturition and higher incidence of diabetes compared to younger and middle-aged patients. Male gender, tumour size (≥ 5 cm), poor differentiation, later stage, adjuvant chemotherapy, damaged micturition, hypertension or diabetes are associated with a worse prognosis for rectal cancer patients (P < 0.05). However, smoking is a favourable factor to the patients (P = 0.018). Age of ≥ 70 years is an independent prognostic factor for patients with rectal cancer after surgery (P = 0.000) and elderly patients with Stage II and III disease receiving adjuvant chemotherapy show a favourable prognosis. The elderly patients who suffered from diabetes receiving adjuvant chemotherapy have a poor prognosis. Further prospective and large population studies are warranted to confirm the findings of this study.

Abstract
BACKGROUND The 5-year survival rate of the patients with stage I colorectal cancer is about 90%; therefore, adjuvant therapy has not been recommended after radical resection; however, about 16-26% of T2N0M0 patients will be dead at 5 years despite radical curative resection. It indicated that there is a defined group of patients who are at high risk for relapse or metastasis despite radical operation. This study aimed to find the patients with T2N0M0 colorectal cancer at high risk for relapse or metastasis. METHODS From January 1993 to December 2014, 812 patients with histologically confirmed stage T2N0M0 primary colorectal cancer treated by radical surgery with complete clinical follow-up data were eligible for this study. The medical records of all patients were collected and were retrospectively analyzed. Survival rates were calculated using Kaplan-Meier method, and survival cures were compared using the log-rank test. Cox proportional hazards model was used to analyze the significant factors defined in univariate test. RESULTS The 5-year and 10-year overall survival rates were 81.9 and 67.7%, respectively. Male gender, old age, lymphovascular permeation, perineural invasion, and poor differentiation were associated with low cancer-specific survival rates in Kaplan-Meier analysis. Multivariate analyses revealed old age, lymphovascular permeation, perineural invasion, and poor differentiation as significant independent factors predicting worse prognosis (P < 0.05). CONCLUSIONS Old age, lymphovascular permeation, perineural invasion, and poor differentiation are risk factors for the worse prognostic patients with T2N0M0 colorectal patients who would potential benefit from more aggressive therapy.

Abstract
OBJECTIVE Currently, no published studies have compared the clinical outcomes of the medial-to-lateral approach (MA) and lateral-to-medial approach (LA) for open right hemicolectomy. Thus, the present study aimed to assess whether one of these approaches has any potential benefits over the other. METHODS A retrospective study was performed of all patients who underwent open right hemicolectomy with pathologically confirmed disease who met the eligibility criteria between June 2008 and June 2012. The population was divided into an MA group and an LA group by propensity scoring. We compared patient demographic and clinical characteristic variables between the two groups and assessed short-term and long-term outcomes. RESULTS A total of 450 patients (MA, n = 150; LA, n = 300) were evaluated. The operation time (MA,138.4 minutesvs.LA,166.2 minutes; P < .05) and blood loss (MA,52.0mL vs. LA,62.6mL; P < .05)were significantly lower in the MA group. No differences in the number of harvested lymph nodes and oncologic outcomes were observed between the two groups. Further subgroup analysis for stage III colon cancer revealed that the MA group had significantly more retrieved lymph nodes (MA,18.8vs. LA,16.0; P = .028). There were no differences in other variables between the two groups. CONCLUSIONS The MA reduced operative time and blood loss compared with the LA. We thus concluded that the MA provided short-term benefits compared with the LA in open right hemicolectomy for right-sided colon cancer.

Abstract
BACKGROUND Currently, the predictors of readmission after colectomy specifically for ulcerative colitis (UC) are poorly investigated. We sought to determine the rates and predictors of 30-day readmissions after colectomy for UC. METHODS Patients undergoing total proctocolectomy and end ileostomy, abdominal colectomy with end ileostomy, proctocolectomy with ileoanal pouch anastomosis (IPAA) formation and diverting ileostomy, one stage IPAA, or abdominal colectomy with ileorectal anastomosis at a tertiary care center between January 2002 and January 2012 for UC were included. Patients were identified using ICD-9 code 556.x. Each record was manually reviewed. The electronic record system was reviewed for demographic information, medical histories, UC history, medications, and data regarding the admission and discharge. Charts were reviewed for readmissions within 30 days of surgery. Univariate and multivariate analyses were performed using Stata v.13. RESULTS Two hundred nine patients with UC underwent a colectomy. Forty-three percent had a proctocolectomy with IPAA and diverting ileostomy and 32% had abdominal colectomy with end ileostomy. Seventy-six percent of surgeries were due to failure of medical therapy and 68% of patients were electively admitted for surgery. Thirty-two percent (n = 67/209) of the cohort was unexpectedly readmitted within 30 days. In multivariate model, proctocolectomy with IPAA and diverting ileostomy (odds ratio [OR] = 2.11; 95% CI, 1.06-4.19; P = 0.033) was the only significant predictor of readmission. Hospital length of stay >7 days (OR = 1.82; 95% CI, 0.98-3.41; P = 0.060), presence of limited UC (OR = 2.10; 95% CI, 0.93-4.74; P = 0.074), and steroid before admission (OR = 1.69; 95% CI, 0.90-3.2; P = 0.100) trended toward significance. CONCLUSIONS Surgery for UC is associated with a high rate of readmission. Further prospective studies are necessary to determine the means to reduce these readmissions.

Abstract
BACKGROUND Schistosomiasis is an infectious disease that affects more than 230 million people worldwide, according to conservative estimates. Some studies published from China and Japan reported that schistosomiasis is a risk factor for colorectal cancer in Asia where the infective species is S. japonicum. However, there have been only few reports of prognosis of patients with schistosomal rectal cancer SRC. OBJECTIVES This study aimed to analyze differences in prognosis between SRC and non-schistosomal rectal cancer(NSRC) with current treatments. MATERIALS AND METHODS A retrospective review of 30 patients with schistosomal rectal cancer who underwent laparoscopic total mesorectal excision operation (TME) was performed. For each patient with schistosomal rectal cancer, a control group who underwent laparoscopic TME with non-schistosomal rectal cancer was matched for age, gender and tumor stage, resulting in 60 cases and controls. RESULTS Univariate analysis showed pathologic N stage (P=0.006) and pathologic TNM stage (P=0.047) statistically significantly correlated with disease-free survival (DFS). Pathologic N stage (P=0.014), pathologic TNM stage (P=0.002), and with/without schistosomiasis (P=0.026) were statistically significantly correlated with overall survival (OS). Schistosomiasis was the only independent prognostic factor for DFS and OS in multivariate analysis. CONCLUSIONS The prognosis of patients with schistosomal rectal cancer is poorer than with non-schistosomal rectal cancer.

Abstract
Colorectal cancer is the third most commonly diagnosed type of cancer in the world. Prostate adenocarcinoma is the most common male genitourinary tract malignancy, usually occurring after the age of 60. Prostate adenocarcinoma is a highly metastatic cancer. The common metastatic locations of prostate cancer are the bone, lung and liver. The elective locations are bones. Solitary rectal metastasis of prostate cancer is relatively rare. In the present study we report a case of solitary metastasis of a prostate adenocarcinoma with the prostatic capsule intact, which initially led to an incorrect diagnosis.

Abstract
Guidelines on the appropriate use of perioperative steroids in patients with inflammatory bowel disease (IBD) are lacking. As a result, corticosteroid supplementation during and after colorectal surgery procedures has been shown to be highly variable. A clearer understanding of the indications for perioperative corticosteroid administration relative to preoperative corticosteroid dosing and duration of therapy is essential. In this review, we outline the basic tenets of the hypothalamic-pituitary-adrenal (HPA) axis and its normal response to stress, describe how corticosteroid use is thought to affect this system, and provide an overview of the currently available data on perioperative corticosteroid supplementation including the limited evidence pertaining to patients with inflammatory bowel disease. Based on currently existing data, we define "adrenal suppression," and propose a patient-based approach to perioperative corticosteroid management in the inflammatory bowel disease population based on an individual's historical use of corticosteroids, the type of surgery they are undergoing, and HPA axis testing when applicable. Patients without adrenal suppression (<5 mg prednisone per day) do not require extra corticosteroid supplementation in the perioperative period; patients with adrenal suppression (>20 mg prednisone per day) should be treated with additional perioperative corticosteroid coverage above their baseline home regimen; and patients with unclear HPA axis function (>5 and <20 mg prednisone per day) should undergo preoperative HPA axis testing to determine the best management practices. The proposed management algorithm attempts to balance the risks of adrenal insufficiency and immunosuppression.

Abstract
BACKGROUND Laparoscopic colorectal resection has been gaining popularity over the past two decades. However, studies about laparoscopic rectal surgery in elderly patients with long-term oncologic outcomes are limited. In this study, we evaluated the short-term and long-term outcomes of laparoscopic and open resection in patients with rectal cancer aged ≥ 70 y. METHODS From 2007-2012, a total of 294 consecutive patients with rectal cancer from a single institution were included, 112 patients undergoing laparoscopic rectal resection were compared with 182 patients undergoing open rectal resection. RESULTS Seven (6.3%) patients in the laparoscopic group required conversion to open surgery. The two groups were well balanced in terms of age, gender, body mass index, American society of anesthesiologists scores, site, and stage of the tumors. Laparoscopic surgery was associated with significantly longer median operating time (220 versus 200 min; P = 0.005), less estimated blood loss (100 versus 150 mL; P < 0.001), a shorter postoperative hospital stay (8 versus 11 d), lower overall postoperative complication rate (15.2% versus 26.4%; P = 0.025), wound-related complication rate (7.14% versus 17.03%; P = 0.015), less need of blood transfusion (8.04% versus 16.5%; P = 0.038), and surgical intensive care unit after surgery (12.5% versus 22.0%; P = 0.042) when compared with open surgery. Mortality, quality of surgical specimen, lymph nodes harvested, positive distal, and circumferential margin rate were not significantly different between two groups. The estimated 3-y survival rates were similar between two groups. CONCLUSIONS Laparoscopic rectal surgery is safe and feasible in patients >70 y and is associated with better short-term outcomes when compared with open surgery.
