ABSTRACT

Objective:To explore the safety of transanal re-excision (TAR) after positive-margin local resection for early rectal cancer.Methods:A retrospective analysis was made data of 44 patients with rectal cancer after local excision from Mar 2006 to Oct 2018 at the Department of Colorectal Surgery, Cancer Hospital of Chinese Academy of Medical Sciences. All patients had positive margin or suspicious tumor remains after local excision, and subsequently salvage TAR surgery was performed after informed consent was given.Results:Forty-four patients after local excision were with pathologically showed residual condition, including 26 cases of positive margin and 18 cases of suspicious tumor remaining. The pathological types were all adenocarcinoma. Forty-one (93%) patients with pT1 and 3 (7%) patients with pT2. The median follow-up time after salvage TAR was 100 (11-164) months. During follow-up, 3 patients (7%) developed mild anal incontinence. One patient (2%) had local recurrence, 3 (7%) patients had distant metastases, and 3 patients (7%) died of non-tumor specific deaths. The overall 5-year survival rate and disease-free survival rate were 98% and 93 %, respectively.Conclusions:Transannal full thickness tumor re-excision is safe and reliable for the salvage treatment after non-complete local resection of early rectal cancer. The long-term follow-up results show that the 5-year survival rate is comparable to that of radical surgical resection, and with a good anal function.

ABSTRACT

Objective@#To investigate the safety and feasibility of laparoscopic remedial surgery in patients who didn′t reach the cure criterion of early colorectal cancer after endoscopic resection.@*Methods@#The clinical and follow-up data of 12 patients who didn′t reach the cure criterion of early colorectal cancer and then underwent endoscopic resection was collected. The clinicalpathological features and remedial indications were analyzed to evaluate the effects of laparoscopic remedial surgery.@*Results@#The average number of lymph nodes in the lymph node dissection was 15 during remedial surgery, and 3 of them had lymph node metastasis. Among the 3 patients with residual cancer, two cases were poorly differentiated, 1 case was moderately differentiated, 1 case was positive for basal margin, and 1 case had vascular invasion. No lymph node metastasis occurred in the 9 patients who had no residual cancer. Among these, 8 cases were moderately differentiated, 1 case was poorly differentiated and 2 cases had positive basal margin. The average follow-up duration was 40 months and all 12 patients were in a state of survival at the last follow-up. During the follow-up of the 3 patients with residual cancer, 1 patient received adjuvant chemotherapy with unknown prognosis; 1 patient received postoperative adjuvant radiochemotherapy, and lung metastasis occurred; 1 patient did not receive any treatment after surgery and survived for 33 months.@*Conclusions@#Laparoscopic remedial surgery is a safe and feasible remedy for patients who didn′t reach the cure criterion of early colorectal cancer after endoscopic resection. However, the choice of remedial strategy for colorectal carcinoma needs further investigation for patients with no vascular invasion, high degree of differentiation, and negative basal margin.

ABSTRACT

Objective@#To evaluate the compliance rate of screening colonoscopy and associated factors in high-risk populations of colorectal cancer (CRC) in urban China.@*Methods@#CRC screening data from the Program of Cancer Screening in Urban China conducted in 12 provinces in 2012-2014 was used in the present study. All 97 445 participants were asked to take epidemiological questionnaire survey to evaluate their cancer risk. Participants who were evaluated as "high risk for CRC" were recommended to receive colonoscopy at designated hospitals. Chi-square tests were used to compare the differences of participation rates between groups. Multivariate logistic regression models were applied to explore the potential factors associated withthe compliance rate of screening colonoscopy.@*Results@#Overall, 97 445 participants of CRC high-risk were included in this analysis, and 14 949 of them took screening colonoscopy, yielding a participation rate of 15.3%. The participation rate varied greatly across provinces, ranging from 25.2% (2 785/11 071) in Heilongjiang to 9.7% (1 698/17 515) in Liaoning. Moreover, the participation rate in 2013-2014 was significantly higher than that in 2012-2013 (17.1%(9 766/57 280) vs 12.9% (5 183/40 165), χ2=57.67, P<0.001) . The multivariate logistic regression analyses showed that: compared with individuals of 40-49 years old, individuals of 50-59 or 60-69 years old were more willing to accept screening colonoscopy, with OR of 1.17 (95% CI: 1.12-1.22) and 1.13 (95% CI: 1.08-1.19), respectively; compared with uneducated individuals, individuals with good educational background of equivalent to high school or higher (OR=1.29, 95% CI:1.10-1.50) were more willing to accept screening colonoscopy; compared with individuals who never took fecal occult blood tests (FOBT) before, individuals with previous positive FOBT results (OR=1.40, 95% CI:1.31-1.50) were more willing to accept screening colonoscopy; compared with individuals with no inflammatory bowel diseases (IBD), individuals with IBD (OR=1.63, 95%CI:1.56-1.69) were more willing to accept screening colonoscopy; Compared with individuals without polyp history, individuals having history of previous polyp detection (OR=1.43, 95% CI:1.37-1.50) were more willing to accept screening colonoscopy; compared to individuals with no family history of CRC, individuals with history of CRC (OR=1.60, 95% CI:1.53-1.66) were more willing to accept screening colonoscopy.@*Conclusion@#The overall participation rate of screening colonoscopy among high-risk population of CRC in the 12 participating sites was 15.3%. The study findings indicated that age, education level, history of past fecal occult blood test, IBD, history of polyp, family history of CRC were associated with the compliance rate of colonoscopy in this population-based CRC screening program.

ABSTRACT

Objective:To confirm the potential of growth-related gene productβ(GROβ) as a biomarker for colorectal cancer. Methods:Serum GROβlevels in 123 subjects with colorectal cancer, 88 healthy controls, and 125 subjects with other diseases were measured using enzyme-linked immunosorbent assay. Serum levels of carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) in all subjects were measured using immunoluminometric assay. Statistical analyses were conducted to determine the associa-tions between serum GROβlevels and clinical parameters for colorectal cancer. The receiver operating characteristic (ROC) curves of GROβ, CEA, and CA19-9 were analyzed. Results:The serum GROβlevels were higher in patients with colorectal cancer (median=96.15 pg/mL) than in the healthy controls (median=43.28 pg/mL, P<0.01) and in patients with other diseases (median=57.30 pg/mL, P<0.01). The serum GROβlevels in patients with colorectal cancer were positively correlated with the tumor-node-metastasis staging (P<0.01) and depth of infiltration (P<0.05), but not with the histological grade, tumor embolus, lymph node metastasis, gross pathologic tu-mor type, or gender of the patients. The sensitivity and specificity of the assay for serum GROβwere 56.1%(69/123) and 95.31%(203/213), respectively. The diagnostic sensitivity was 22.2%(4/18) for stage I and 66.7%(26/39) for stage II when the data of GROβwere combined with the data of CEA and CA19-9. The ROC curve constructed with the data of GROβ(0.834) was larger than that construct-ed with the data of CEA (0.739) or CA19-9 (0.676) for discriminating colorectal cancer from the matched controls. Conclusion:These preliminary results indicated that the serum GROβlevel could be a useful biomarker for colorectal cancer diagnoses.

ABSTRACT

ObjectiveTo evaluate the safety and effects of pseudomonas aerug PA-MSHA vaccine on cytoimmunity in advanced gastric cancer patients. MethodsSeventy two patients with advanced gastric cancer were randomly divided into experimental group and control group. Tumor bed was treated intraoperatively by pseudomonas vaccine injection in experimental group.The venous bloods were sampled prior to surgery (preoperative) and on days 10,20,and 30 postoperatively.The total lymphocyte count and lymphocyte subpopulations were detected while the postoperative complications and adverse drug reaction were observed,prognosis was evaluated. ResultsThe total lymphocyte count(P =0.042) and the counts ofCD3+ lymphocyte(P =0.027) and NK cell increased (P =0.012) obviously in experimental group.CD8+ lymphocyte decreased(P =0.037),but the counts of CI4+ lymphocyte and CD4+/CD8+ were not significantly different.Complications were not significantly different in the two groups.One year survival rate was longer ( 94.9% ) in experimental group than that in the control group ( 83.3% ) ( P =0.022 ).ConclusionsPeritoneal cavity administration with pseudomonas aerug vaccine was safe,and effectively helps regulate cytoimmunity in postoperative patients of advanced gastric carcinoma.
