ObjectiveTo evaluate the value of real-time indocyanine green fluorescence imaging navigation (ICG-FIN) in laparoscopic rectal cancer surgery. MethodsThe patients who adopted ICG-FIN during laparoscopic rectal cancer surgery in the Department of Anorectal Surgery of Xuzhou Central Hospital from April 2022 to June 2023 according to the inclusion and exclusion criteria (ICG-FIN group) were collected, meanwhile matching (1∶1) of patients who did not adopt ICG-FIN during laparoscopic surgery from January 2021 to May 2022 (control group). The general data, surgical conditions, intraoperative and postoperative outcomes between the two groups were compared. ResultsThere were 62 patients in the ICG-FIN group and 62 patients in the control group. There were no statistical differences in the gender, age, body mass index, comorbidities, and so on between the two groups (P>0.05). The tumor localization, lymph node tracing, fluorescence imaging of the intended resection of intestinal tract and anastomotic site were observed in the ICG-FIN group. Seven patients (11.3%) had changed in the intended resection of intestinal anastomotic line during surgery, while there were no changes of the surgical plan in the control group. There were no statistical differences (P>0.05) in terms of surgical method, operative time, intraoperative bleeding, proportion of ileostomy, time of the first postoperative exhaust, postoperative hospital stay, and incidence of short-term complications between the two groups. Compared with the control group, the incidence of anastomotic leakage was lower (P=0.012), and the number of lymph nodes cleaned was more (P=0.016) in the ICG-FIN group. However, there was no statistical difference in the number of positive lymph nodes detected between the two groups (P=0.343). ConclusionsAccording to the results of this study, ICG-FIN is a reliable and effective method during laparoscopic rectal cancer surgery, which can accurately localize tumor, trace and guide lymph node dissection. Real-time evaluation of intestinal blood flow perfusion is of great practical value in reducing anastomotic leakage.

ObjectiveTo systematically evaluate the effect of mucin 1 (MUC1) expression on the prognosis and clinicopathologic characteristics of patients with colorectal cancer.MethodsThe cohort studies on the relationship between MUC1 expression and the prognosis of colorectal cancer patients were retrieved from PubMed, Embase, Web of Science, Cochrane Library, CNKI, China Biology Medicine, WanFang, VIP, and other databases from the establishment of the database to December 2020. The two researchers screened the literatures according to the inclusion and exclusion criteria, extracted relevant data, and performed meta analysis using Stata 12.0 software.ResultsA total of 17 eligible studies comprising 2 516 patients with colorectal cancer were included. The results of meta-analysis showed that the overall survival (OS) of patients with high MUC1 expression was worse than that with low MUC1 expression [HR=1.51, 95%CI (1.33, 1.71), P<0.001], but not statistically significant with disease-free survival [HR=1.39, 95%CI (0.41, 4.68), P=0.565]. Subgroup analysis results showed the same results as the overall analysis regardless of analysis method (multivariate or survival curve), different ethnic groups (Asian or Caucasian), and different sample sizes (≥100 or <100). The results of clinicopathologic analysis showed that the high expression of MUC1 was correlated with lymph node metastasis, distant metastasis, depth of invasion, and TNM stage (P<0.05), but not correlated with gender, age, degree of tumor differentiation, and tumor location (P>0.05).ConclusionsHigh expression of MUC1 is closely associated with poor prognosis, lymph node metastasis, distant metastasis, tumor invasion depth, and TNM stage in patients with colorectal cancer, which is expected to be an important reference indicator for disease monitoring and prognosis judgment of colorectal cancer.
Objective
To understand status of technical realization, present development, faced problems, and application prospects of reduced-port laparoscopic surgery for rectal cancer, and to analyze safety and feasibility so as to provide theoretical and practical basis for clinical application and promotion.
Method
By searching the databases such as Medline, Embase, and Wanfang, etc., the relevant literatures about reduced-port laparoscopic surgery for rectal cancer were collected and reviewed.
Results
At present, the most common reduced-port laparoscopic surgery was the 1-port laparoscopic surgery, 2-port laparoscopic surgery, and 3-port laparoscopic surgery. The 1-port laparoscopic surgery had the effects of minimal invasiveness and cosmesis, but it was difficult to perform. The 2-port laparoscopic surgery for rectal cancer preserved as far as possible the effect of minimal invasiveness, the difficulty of procedure was reduced greatly, which was easy to be learnt and promoted. The experience of the 3-port laparoscopic surgery for rectal cancer contributed to the technical development of the 1-port laparoscopic surgery, with no need for the assisted incision for intraoperative specimen. The reduced-port laparoscopic surgery for rectal cancer was technically feasible and safe, which possessed the equal or better short-term outcomes as compared with the conventional 5-port laparoscopic or open surgery beside the radical resection for rectal cancer. However, the stringent technique for the laparoscopic surgery was necessary and it needed to overcome the learning curve.
Conclusions
Reduced-port laparoscopic surgery has some obvious advantages in minimal invasiveness, cosmesis, and enhanced recovery. More large-sample, multi-center, randomized controlled trials are eager to further confirm safety, effectiveness, and feasibility of reduced-port laparoscopic surgery for rectal cancer.
ObjectiveTo study the expression of apoptosissuppressing gene (bcl2) and apoptosispromoting gene (bax) in colorectal cancerous tissue and transitional mucosas. MethodsColorectal cancerous tissue, transitional mucosas (3 cm from the cancerous tissue) and normal tissue were taken respectively in thirtyone cases. Immunohistochemical technique SP method was used to detect the expression in those tissues. ResultsThe positive expression rate of bcl2 protein in cancerous tissue and transitional mucosa were 64.5%and 60.0% respectively and significantly higher than that in normal tissue (P＜0.05). The positive expression rate of bcl2 protein in normal tissue was 35.0%. The positive expression rate of bax protein in cancerous tissue and transitional mucosa were 45.2%and 45.0% respectively and significantly lower than that in normal mucosa (P＜0.05). The positive expression rate of bax protein in normal tissue was 60.0%. There was no obvious difference in the positive rate of bax and bcl2 protein between cancerous tissue and transitional mucosa (Pgt;0.05). The expression rate of bax and bcl2 protein in colorectal cancer was irrelative to clinical pathological gradation and clinical stage (Pgt;0.05). ConclusionThere is over expression of bcl2 protein and low expression of bax protein in colorectal cancer and transitional mucosa. bcl2 protein and bax protein can affect the generation of colorectal cancer by participating in the regulation of apoptosis. But it is irrelative to clinical pathological gradation and clinical stage. Transitional mucosas should be viewed as precancerous lesion and resected during operation.
Objective To explore the clinical value, latest research progress, and clinical controversy of total neoadjuvant therapy (TNT) in locally advanced rectal cancer (LARC). Method We searched and reviewed on the latest literatures about studies of the clinical research of TNT in LARC. Results TNT could make the tumor downstage rapidly and improve the patients’ treatment compliance. In terms of organ preservation rate, 3-year disease-free survival and pathological complete remission rate, TNT had advantages and was a especial potential treatment strategy compared with traditional methods. Conclusions TNT decreases local recurrence rate and improves the long-term survival. For LARC patients with strong desire for organ preservation, TNT is a good treatment choice and has the value of clinical promotion.
ObjectiveTo analyze the characteristics of adjuvant treatment of colorectal cancer in the Database from Colorectal Cancer (DACCA).MethodsThe informations in the DACCA database were screened, including adjuvant therapy (adjuvant strategy, compliance), adjuvant chemotherapy (indication selection, acceptance, actual cycles of chemotherapy, effect, and standardized application), adjuvant radiotherapy (indication selection, acceptance, and effect), and targeted therapy (uses of oral and intravenous targeted drugs). The data that at least one of items must not be “empty” were selected.ResultsA total of 3 955 data items were analyzed for colorectal cancer adjuvant therapy. ① The highest data composition ratio of “planned strategy of adjuvant therapy” and “compliance of adjuvant therapy” was “adjuvant therapy” (35.6%, 929/2 611) and “coordination” (28.1%, 664/2362), respectively. ② The highest data composition ratios of “indication of chemotherapy”, “acceptance of chemotherapy”, “cycles of chemotherapy”, “effect of chemotherapy”, and “chemotherapy based guidelines” were “must” (38.6%, 1 140/2 963), “rejection” (53.1%, 1 373/2 586), “6-cycle adjuvant chemotherapy” (12.4%, 338/2 722), “stability” (59.9%, 618/1031), and “standardization” (78.6%, 903/1 149). There was an obvious relationship between the planned strategy of adjuvant chemotherapy and the final acceptance of chemotherapy (χ2=505.262, P<0.001), that was, when the planned strategy of adjuvant chemotherapy was “optional”, the proportion of final rejection was very high (89.0%, 137/154). ③ The highest data composition ratios of “indication of radiation”, “acceptance of radiation”, and “effect of radiation” were “unnecessary” (49.1%, 1 423/2 915), “rejection” (93.8%, 2 629/2 803), and “stability” (38.1%, 45/118). There was a correlation between the planned strategy of adjuvant radiotherapy and the final acceptance of radiotherapy (χ2=139.593, P<0.001), that was, when the patients who should receive radiotherapy had not high acceptance (10.6%, 127/1 194), and the patients who should select optional radiotherapy all refused radiotherapy (100%).④ The data composition ratios of “none” of oral and intravenous targeted therapy drugs in targeted therapy were the highest, at 84.2% (2 121/2 520) and 73.3% (206/281), respectively. ConclusionBy expounding the characteristics of the current adjuvant treatment of colorectal cancer in DACCA, it provides a reference for the adjuvant treatment of colorectal cancer.

【Abstract】ObjectiveTo investigate the relationship between expression of Seprase and the clinicopathologic characteristics in colorectal cancer. MethodsThe expression of Seprase in 50 cases of colorectal cancer was detected with immunohistochemistry, Western-blotting technique and semi-quantitative immunohistochemistry, and the relationship between the expression of Seprase and the clinicopathologic characteristics (age, gender, tumor location, tumor size, gross appearance, depth of infiltration, histological classification, lymph node metastasis, venous infiltration, Dukes stage, distant metastasis) was analyzed. ResultsThe expression of Seprase was found both in tumor cells and adjacent stromal cells. The level of Seprase protein was higher in cancer tissue than that in normal tissue, and a semiquantitative assessment of the immunohistochemistry revealed a significant correlation between Seprase expression and the Dukes stage and the lymph node metastasis. ConclusionThe abundant expression of Seprase in colorectal cancer tissue is associated with the Dukes stage and the lymph node metastasis.
Objective To explore the clinical effects of postoperative restrict rehydration on different body mass index (BMI) of patients with colorectal cancer. Methods From January 2008 to January 2009, the patients diagnosed definitely as colorectal cancer were analyzed retrospectively. The postoperative early rehabilitations were studied and compared in different fluid therapy with different BMI (underweight group, normal group, overweight group).Results The first defecation time, aerofluxus time and ambulation time of the fluid restriction group were significantly earlier than those of the tradition therapy group (Plt;0.05), and postoperative in-hospital time was also less (Plt;0.05). However, the differences of early postoperative rehabilitation among underweight group, normal group and overweight group in the tradition therapy group and fluid restriction group had no statistical significance (Pgt;0.05). The complications such as pulmonary infection, anastomotic leakage, intestinal obstruction and wound dehiscence in the fluid restriction group were significantly lower than those in the tradition therapy group (Plt;0.05). In the tradition therapy group, the incidences of anastomotic leakage and wound dehiscence in overweight group were significantly higher than those in the underweight and normal group (Plt;0.05). The rate of postoperative complications among underweight group, normal group and overweight group in the fluid restriction group had no statistical significance (Pgt;0.05). Conclusion Postoperative restrict rehydration for overweight colorectal cancer patients has a good clinical effect, which can promote the early postoperative rehabilitation.
