ABSTRACT

Preoperative treatment of colorectal cancer includes neoadjuvant therapy for initial resectable patients and conversion therapy for initial unresectable patients. In locally advanced rectal cancer, on the basis of neoadjuvant chemoradiotherapy or radiotherapy, increasing the intensity of concurrent chemotherapy, or raising postoperative adjuvant chemotherapy before surgery, or combining with immunotherapy can increase pathological downstaging, contribute to organ preservation, and improve survival of patients. In locally advanced colon cancer, neoadjuvant chemotherapy can improve surgical outcomes. In patients with resectable colorectal liver metastases, neoadjuvant chemotherapy is recommended in patients with unfavorable prognostic factors, but it remains controversial whether it should be combined with targeted therapy. However, in patients with initially unresectable colorectal liver metastases, under the guidance of molecular typing, chemotherapy, especially triple-drug chemotherapy, combined with targeted therapy, is expected to achieve higher objective response rate and convertible rate, thus accepting surgical resection, which improves long-term survival. In addition, for the patients with mismatch repair deficient/micro-satellite instability-high metastatic colorectal cancer, programmed death-1 monoclonal antibody (mAb) and/or cytotoxic T lymphocyte-associated antigen-4 mAb have become the standard first-line treatment option.

ABSTRACT

Objective:To investigate the risk factors for lymph node metastasis in T1 colorectal cancer and application value of its nomogram prediction model.Methods:The retrospective case-control study was conducted. The clinicopathological data of 914 patients with T1 colorectal cancer who underwent radical resection in the Zhongshan Hospital of Fudan University from June 2008 to December 2019 were collected. There were 528 males and 386 females, aged from 25 to 87 years, with a median age of 63 years. Observation indicators: (1) clinicopathological data of patients with T1 colorectal cancer; (2) follow-up; (3) analysis of influencing factors for lymph node metastasis; (4) development and internal validation of a nomogram predition model. Patients were regularlly followed up once three months within postoperative 2 years and once six months thereafter to detect tumor recurrence and survival. The endpoint of follow-up was at postoperative 5 years. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M (range). Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. The Kaplan-Meier method was used to calculate survival rates and draw survival curves. The Log-rank test was used for survival analysis. Univariate and multivariate analyses were performed using the Logistic regression analysis. Based on results of multivariate analysis, a Logistic regressional nomogram for prediction of lymph node metastasis probability was constructed using R language software. The calibration curve was used to evaluate the consistency between probability predicted by the nomogram model and actual observation probability, which was reprensented by a consistency index. The Bootstrap method was used for evaluation of the model performance to receive the calibration curve. The Hosmer-Lemeshow test was used to calculate the goodness of fit in model. Results:(1) Clinicopathological data of patients with T1 colorectal cancer: 687 of 914 patients underwent direct surgery and 227 underwent remedial operation after endoscopic resection. All the 914 patients were confirmed as pT1NxM0 colorectal cancer by pathological examination. The tumor diameter was (2.3±1.2)cm. The pathological catogaries of 914 patients included 865 cases of adenocarcinoma and 49 cases of mucinous adenocarcinoma. The tumor differentiation degree of 914 patients included 727 cases of high or middle differentiation and 187 cases of low differentiation or undifferentiation. Of the 914 patients, 633 cases had submucosal infiltration depth ≥1 000 μm and 281 cases had submucosal infiltration depth <1 000 μm. There were 110 cases with nerve vessel invasion and 804 without nerve vessel invasion. The number of intraoperative lymph node dissection was 13 (range, 1-48). There were 804 cases in stage N0 of N staging, 98 cases in stage N1 and 12 cases in stage N2. There was no perioperative death. (2) Follow-up: 886 of 914 patients were followed up for 25 months (range, 1-129 months). During the follow-up, 24 patients had tumor recurrence or metastasis. The 5-year cumulative tumor recurrence rate of 914 patients was 4.8% and the median recurrence time was 17.0 months. Liver was the main site of tumor recurrence, accounting for 58.3%(14/24). The 5-year recurrence-free survival rate of 914 patients was 95.2%. The 5-year recurrence-free survival rate was 96.3% of 804 patients without lymph node metastasis, versus 86.6% of 110 patients with lymph node metastasis, showing a significant difference between the two groups ( χ2=6.83, P<0.05). (3) Analysis of influencing factors for lymph node metastasis: results of univariate analysis showed that preoperative carcinoembryonic antigen (CEA), preoperative CA19-9, tumor differentiation degree, submucosal infiltration depth, nerve vessel invasion were related factors for lymph node metastasis in T1 colorectal cancer ( odds ratio=2.56, 3.25, 2.21, 2.68, 3.39, 95% confidence interval as 1.41-4.67, 1.22-8.66, 1.43-3.41, 1.56-4.88, 2.10-5.48, P<0.05). Results of multivariate analysis showed that preoperative CEA ≥5 μg/L, preoperative CA19-9 ≥37 U/mL, poor differentiation or undifferentiation, submucosal infiltration depth ≥1 000 μm and nerve vessel invasion were independent risk factors for lymph node metastasis in T1 colorectal cancer ( odds ratio=2.23, 3.47, 2.01, 2.31, 2.91, 95% confidence interval as 1.02-4.15, 1.08-10.87, 1.03-3.27, 1.40-4.47, 1.64-5.13, P<0.05). (4) Development and internal validation of a nomogram predition model: based on results of multivariate Logistic analysis, a nomogram prediction model for lymph node metastasis in T1 colorectal cancer was developed. The nomogram score was 59 for preoperative CEA >5 μg/L, 100 for preoperative CA19-9 ≥37 U/mL, 48 for poor differentiation or undifferentiation, 67 for submucosal infiltration depth ≥1 000 μm and 92 for nerve vessel invasion, respectively. The total of different scores for different clinicopathological factors corresponded to the probability of lymph node metastasis. The receiver operating characteristic curve was drawed to evaluate the predictive performance of nomogram for lymph node metastasis in T1 colorectal cancer, with the area under curve of 0.70(95% confidence interval as 0.64-0.75, P<0.05). The Bootstrap internal validation of predictive performance in the nomogram predition model showed a consistency index of 0.70 (95% confidence interval as 0.65-0.75). The calibration chart showed a good consistency between the probability predicted by the nomogram model and actual probability of lymph node metastasis. The Hosmer-Lemeshow test showed a good fitting effect in model ( χ2=1.61, P>0.05). Conclusions:Preoperative CEA ≥5 μg/L, preoperative CA19-9 ≥37 U/mL, poor differentiation or undifferentiation, submucosal infiltration depth ≥ 1 000 μm and nerve vessel invasion are independent risk factors for lymph node metastasis in T1 colorectal cancer. The constructed nomogram model can help predict the probability of lymph node metastasis in T1 colorectal cancer.

ABSTRACT

Robotic surgical system has been widely applied in sphincter-preserving surgery for low rectal cancer with the advantages of clear 3D images and stably flexile manipulation. Its application principle includes radical resection of tumor and complete preservation of function. The main operation procedures of robotic surgical system in sphincter-preserving surgery for low rectal cancer are as follows: (1) Anterior resection of low rectal cancer: It is safe and feasible and has obvious advantages in observation of pelvic nerves, dissociation of presacral and sacral side, and high rate of sphincter-preserving, while the improvement of postoperative recovery and long-term survival needs to be verified by further large sample researches. (2) Per anus intersphincteric resection (ISR): It is mainly applied in T1 and T2 stage tumors with 2 cm distance from tumor low margin to anal edge after dissociation of mesorectum. The greater difficulty of manipulation is found in ISR, while robotic surgical system can complete the intersphincteric resection by transabdominal approach, but anal function may be affected with the possibility of feces spillage at night, so robotic ISR is now still in exploration stage. (3) Transanal everted pull-through resection (Welch resection): Associated application of this operation is rarely reported at home and abroad. Our department has completed 51 robotic procedures of Welch resection till March 2017. Welch resection is successfully performed in all the patients. The short-term clinical outcomes are quite satisfactory and long-term survival is followed up. We think that this procedure is safe and feasible under the strict mastering of indications. Owing to special manipulation advantages of quickly precise dissociation, cutting and anastomosis in small pelvic space, when compared to laparoscopic surgery, robotic surgical system has higher sphincter-preserving rate for low rectal cancer, however, no other advantages are found. We believe that with the development of surgical instruments and ongoing of large sample studies, robotic surgical system will play a more important role in the treatment of low rectal cancer.

ABSTRACT

Surgical resection of the metastases offers the only opportunity for long-term survival in colorectal liver metastases. However, only 10% to 20% of patients present with resectable disease, and so how to increase surgical patients has been a clinical hotspot. In addition to expanding surgical indications, two-stage hepatectomy and convertible therapy are optional. In convertible therapy, initial treatment regimen decides long-term benefit, and it is important to select appropriate patient population in addition to Ras status when anti-epithelial growth factor receptor monoclonal antibody is used. Minimally invasive surgery can also be used for liver resection and simultaneous resection, and it is safe and effective. For patients with colorectal cancer and unresectable asymptomatic liver metastases, the debate continues over the efficacy of primary resection compared to chemotherapy alone, limited by lack of prospective evidence. Therefore, multidisciplinary team assessment is essential to optimize outcomes in colorectal liver metastases.

ABSTRACT

The incidence and mortality of colorectal cancer (CRC) increased rapidly in recent decades and become enormous challenges in China.Lack of effective early warning of molecular markers and dynamic monitoring technology in term of early diagnosis,treatment evaluation,dynamic recurrence and metastasis monitoring are the clinical diagnosis and treatment bottlenecks of CRC.Traditional diagnosis and treatment of CRC rely on a single level of patient information with low accuracy.Based on the system of biology medical model,to carry out a joint diagnostic model,will overcome the traditional problems through a number of multi-level information integration of the joint diagnosis model,will significantly improve the sensitivity and specificity of diagnosis of CRC.The major challenge in patients with advanced and metastatic CRC is the instability of the tumor genome and the treatment-induced resistance during chemotherapy and targeted therapy.It is necessary to carry out continuous dynamic biopsy in order to accurately guide the development of treatment decisions.Compared with the pathological examination of traditional surgical specimen,liquid biopsy,such as circulating tumor cells,circulating tumor DNA detection technology,with noninvasive,real-time dynamic monitoring,could evaluate the efficacy of treatment,and guide the precise individual diagnosis and treatment.Today,the new strategy and new technology need to undergo clinical trials urgency,through technology optimization,reduction of costs and improvement of detection accuracy,would quickly extended to clinical applications in future.

ABSTRACT

Objective To investigate the effect of early continuous veno-venous hemofiltration (CVVH) on intra-abdominal pressure (IAP) and serum interleukin-6 (IL-6) in severe acute pancreatitis (SAP) patients with abdominal compartment syndrome (ACS).Methods 41 SAP patients with ACS were selected as treatment group and treated with CVVH as well as conventional methods in ICU.The other 12 patients with the same disease were selected as the control group and were only treated with conventional methods because of economic reasons.IAP and blood level of IL-6 in the two groups were measured daily in order to investigate their changes and the correlation between the two parameters.Results The serum IL-6 level and IAP in the two groups were higher on admission day.IAP and serum IL-6 level in the treatment group were significantly decreased on the first day after treatment,and thereafter decreased rapidly.In the control group,IAP and serum IL-6 level were significantly decreased on the 3rd day after treatment.IAP and serum IL-6 level from the 1st day to the 6th day after treatment in the treatment group were significantly lower than those of the control group at the same time point (P<0.05).There was a significant positive correlation between blood IL-6 level and IAP in SAP patients with ACS(r=0.48,P<0.01).IL-6 difference before and after treatment was also positively correlated with the difference of IAP(R=0.39,P<0.05).Conclusions VVH significantly decreased the IAP and the blood level of IL-6 in ACS patients of SAP.The blood level of IL-6 is significantly correlated with IAP,suggesting that IL-6 may play an important role in the pathogenesis of ACS.Therefore early CVVH may clear the cytokines such as IL-6 and lower IAP,thus to prevent multiple organ dysfunction syndrome (MODS),which should be applied in the early stage of ACS.

ABSTRACT

The outstanding advantages of robotic surgery include the stable and three-dimension image and the convenience of surgery manipulation. The disadvantages include the lack of factile feedback, high cost and prolonged surgery time. It was reported that robotic surgery was associated with less trauma stress and faster recovery in elderly patients(≥75 years old) when compared with open surgery. Elderly people have a higher incidence of carcinogenesis and also have more comorbidities and reduced functional reserve. Clinical data of patients over 75 years old treated by robotic surgery in Zhongshan Hospital affiliated to Fudan University from March 2011 to October 2014 were analyzed retrospectively. A total of 24 consecutive patients were included with a median age of 77.8 years old. There were 18 male and 6 female patients. Among them, 14 patients were diagnosed with descending and sigmoid colon cancers while 10 with rectal cancers; 19 had tumor size larger than 5 cm; 16 were diagnosed with ulcerative adenocarcinoma. Fourteen patients were complicated with hypertension, 6 with cardiopulmonary diseases, 4 with diabetes mellitus and 3 with cerebrovascular diseases. Twenty-two patients underwent low anterior resection and 2 abdominoperineal resection. The estimated blood loss was 85 ml; the median operation time was (123.1±45.2) min; the median number of retrieved lymph node was 12.4. Postoperative pathologic results showed that 3 patients were stage I, 10 stage II, and 11 stage III. Postoperative complication was observed in 3 patients: urinary infection in 1 case, intraperitoneal infection in 1 case and atria fibrillation in 1 case, respectively. Median time to first postoperative flatus was 2.8 days. Our results indicated that robotic surgery is safe and feasible in the elderly patients. The next generation of robotic system may make up for these deficiencies through new technologies. With the advantage of more advanced surgical simulator, robotic surgery will play a more important role in the treatment of colorectal cancer patients.

ABSTRACT

Anastomotic leak is a major complication after colorectal resection. Risk factors for anastomotic leak include patient and disease related factors, preoperative factors(e.g. use of neoadjuvant chemoradiation and mechanical bowel preparation), intraoperative factors(e.g. anastomotic techniques, performing of water injection test, preventive colostomy, and surgical procedures, etc; postoperative factors, such as postoperative medication use, etc. Early diagnosis of anastomotic fistula is crucial, which can be made by combining laboratory examination with imaging examination or take the prediction and diagnosis model as reference. Once diagnosed, anastomotic leak should be managed immediately according to individual status and severity of disease. As for intraperitoneal anastomosis, no matter whether the bowel lack of blood supply or not, original anastomosis should be removed and terminal loop ileumstomy should be created. As for extraperitoneal anastomosis(mainly low rectal anastomosis), adequate drainage and terminal loop ileumstomy can be considered when anastomosis is slightly cracked or invisible due to adhesion. When anastomosis is severely cracked or blood supply is too limited, however, we must disconnect the original anastomotic and create a proximal colostomy.

ABSTRACT

ERAS combines modern anesthesia, pain control, and nutritional support technologies, and contains a series of evidence-based perioperative optimization measures, including preoperative preparation, intraoperative anesthesia and postoperative care, to reduce surgical stress and enhance recovery. Several clinical studies and meta-analysis have demonstrated that ERAS can accelerate postoperative rehabilitation in colorectal patients. In addition, minimally invasive colorectal surgery has the advantages of less trauma, less bleeding, and faster postoperative recovery, compared with open surgery. It has become the standard operation for colon resection. Recently 3D laparoscopic and robotic colorectal surgery, which overcomes limitations of conventional laparoscopic surgery, is increasingly used. Therefore, whether ERAS combined with minimally invasive colorectal surgery causes a cumulative advantage receives much concern. A number of studies and meta-analysis have demonstrated that ERAS combined with laparoscopic colorectal cancer surgery can shorten the length of hospital stay and reduce the incidence of complications, as the best perioperative plan for elective colorectal surgery.
