ABSTRACT

γ-synuclein (SNCG) has been extensively studied for its specific overexpression in various malignant neoplasms. Recently, SNCG has been found to be involved in multiple signaling pathways, including estrogen, AKT-mTOR, mitogen-activated protein kinase (MAPK) and microtubule regulation. SNCG has also been found to be related to the proliferation, invasion, migration and chemotherapy drug resistance of neoplasms. Therefore, SNCG is expected to be the key target of anti-tumor and improving the sensitivity of tumor cells to chemotherapeutic drugs.

ABSTRACT

Objective:To evaluate the feasibility of a predictire model composed of non-specific test indexes in early diagnosis of gastric cancer.Methods:From the database of electronic medical record system of Shanghai Changhai Hospital, a total of 24 615 case records were included from January 1, 2010 to April 30, 2019, including 10 497 cases of gastric cancer, 5 198 cases of precancerous diseases, and 8 920 cases of health examination. Through stratified random sampling, the study population was divided into validation set, training set and test set. After data processing and quality control for all laboratory variables, the optimal machine learning algorithm and diagnostic efficiency grouping were selected through four machine learning algorithms, induding the gradient boosting decision tree, random forest, support vector machine, and artificial neural network, and the data were trained by backward stepwise regression method to build the best feature model.Result:In this study, a diagnostic model V22 consisting of 22 routine testing parameters was established. V22 could distinguish early gastric cancer from control group composed of healthy group and precancerous disease, AUC was 0.808, the sensitivity was 85.7%, and the specificity was 91.9%. For CEA negative gastric cancer, V22 also showed high diagnostic accuracy, AUC was 0.801.Conclusion:V22 was a valuable model for the diagnosis of gastric cancer. V22 was an auxiliary diagnostic model of gastric cancer with clinical application value, which could well distinguish early gastric cancer from the control group composed of healthy group and precancerous disease, and the detection rate of early gastric cancer was better than the traditional tumor marker CEA.

ABSTRACT

Objective:To explore the clinical efficacy of radical resection for lung metastasis from colorectal cancer and the prognostic factors.Methods:The retrospective cohort study was conducted. The clinicopathological data of 63 colorectal cancer patients with lung metastasis who were admitted to Peking University Cancer Hospital from January 2004 to December 2015 were collected. There were 35 males and 28 females, aged (57±12)years. Patients underwent radical resection for primary lesion and lung metastasis from colorectal cancer. Observation indicators: (1) diagnosis and treatment; (2) follow-up and survival; (3) prognostic factors analysis. Follow-up was conducte by outpatient examination and telephone interview to detect the survival of patients after operation up to December 2018. Measurement data with normal distribution were represented as Mean±SD, and measurement data with skewed distribution were represented as M (range). Count data were described as absolute numbers or percentages. The Kaplan-Meier method was used to calculate survival rates and draw survival curves. Log-rank test was used for univariate analysis and COX proportional hazard model was used for multivariate analysis. Results:(1) Diagnosis and treatment: of 63 patients with lung metastasis from colorectal cancer, 6 had synchronous lung metastasis and 57 had metachronous lung metastasis. Eighteen cases of suspected lung metastasis were initially detected by chest X-ray, and further confirmed by computed tomography (CT). Forty-five cases of suspected lung metastasis were initially detected by chest CT. All the 63 patients underwent radical resection for primary and metastatic lesions. Two of 22 cases undergoing mediastinal lymph nodes dissection were detected one positive lymph node, respectively. All patients recovered well after operation, without severe complications. There were 57 of 63 patients receiving more than 6 months of postoperative adjuvant chemotherapy and targeted therapy based on fluorouracils. (2) Follow-up and survival: 63 patients were followed up for 8-143 months, with a median follow-up time of 58 months. During the follow-up, 19 of 63 patients died, 24 patients had secondary recurrence with a 5-year recurrence rate of 38.1%(24/63) and a recurrence interval of 18 months(range, 3-58 months). Of 24 patients with secondary recurrence, 19 had lung metastasis, 3 had brain metastasis, 2 had bone metastasis, 2 had liver metastasis; some patients had multiple metastases. Of 24 patients with secondary recurrence, 5 underwent reoperation and 19 underwent chemotherapy and radiochemotherapy. The 5-year overall survival rate of 63 patients was 62.7%. (3) Prognostic factors analysis: results of univariate analysis showed that location of primary lesion, the number of lung metastases and carcinoembryonic antigen (CEA) level before resection of lung metastasis were related factors for prognosis of patients with lung metastasis from colorectal cancer ( χ2=4.162, 7.175, 6.725, P<0.05). Results of multivariate analysis showed that the number of lung metastases and CEA level before resection of lung metastasis were independent influencing factors for prognosis of patients with lung metastasis from colorectal cancer ( hazard ratio=2.725, 2.778, 95% confidence interval as 1.051-7.064, 1.072-7.021, P<0.05). Conclusions:Radical resection for lung metastasis from colorectal cancer is safe and feasible. The number of lung metastases and CEA level before resection for lung metastasis are independent influencing factors for prognosis of patients with lung metastasis from colorectal cancer.

ABSTRACT

OBJECTIVE@#To summarize and analyze the postoperative short-term complications of laparoscope-assisted transanal total mesorectal excision (taTME) for rectal cancer patients after neoadjuvant therapy.@*METHODS@#A prospectively established database on taTME patients at Peking University Cancer Hospital was screened with the following conditions: data retrieval from June 2016 to August 2018, pathologically confirmed adenocarcinoma, receiving preoperative neoadjuvant chemoradiotherapy or chemotherapy. The transabdominal procedure and the transanal procedure were performed simultaneously in the taTME operation. Occurrence of complications during perioperative period (within postoperative 3 months) in these patients, especially anastomosis-related complications and their management were analyzed. The relevant complications were recorded according to the Clavien-Dindo (CD) grading criteria. The severity of anastomotic leakage and anastomotic stenosis was evaluated according to criteria developed by the International Rectal Cancer Research Group.@*RESULTS@#A total of 29 patients were enrolled in this study. In the 29 patients, 25 (86.2%) were male and 4 (13.8%) were female, the median age was 60 (range, 30 to 72) years, the median body mass index was 25.8 (range, 19.8 to 36.4) kg/m, the median distance from the tumor to anal verge was 4 (range, 2 to 8) cm. All the patients completed laparoscope-assisted taTME operations successfully without conversion to laparotomy, intra-operative severe complication or death. The median operation time was 300 (range, 198 to 405) minutes, and the median intra-operative blood loss was 100 (range, 50 to 200) ml. All the TME specimens were complete according to the Nagtegaal standard. All the patients underwent prophylactic ileostomy. Hartmann procedure was performed in one case due to poor blood supply in the proximal bowel without the possibility of anastomosis. Anal sphincter preservation rate was 96.6% (28/29). The median postoperative exhaust time was 2 (range, 1 to 10) days, and the median postoperative hospital stay was 9 (range, 7 to 24) days. Fifteen patients (51.7%) had postoperative complications, among which serious complication (CD grade IIIb and above) accounted for 6.9% (2/29). No perioperative death was observed. Five patients (17.2%) presented anastomosis-related complications, including 2 cases of grade C anastomotic leakage due to anastomotic rupture, who underwent abdominal perineal resection 1 month after operation; 2 cases of grade B anastomotic leakage, who improved after conservative treatment; 1 case of grade A anastomotic stenosis, who improved with anal expansion 1 month after operation. The incidence of postoperative infection was 24.1% (7/29), including 6 cases of pelvic infection and 1 case of trocar site infection, all of which were CD grade II. One case had incomplete intestinal obstruction (CD grade II); 1 case had gastroplegia; 1 case had abdominal trocar hernia. All the patients were followed up for a median of 12.0 (range, 3.9 to 29.9) months. Seven cases did not undergo ileal stoma closure. The anal sphincter preservation rate was 75.9% (22/29).@*CONCLUSION@#Pelvic infection and anastomosis-related complications are common after laparoscope-assisted taTME surgery for rectal cancer patients following neoadjuvant chemoradiotherapy, which require active management and appropriate treatment.

ABSTRACT

Objective@#To understand the perceptions, attitudes and treatment selection of Chinese surgeons on the "watch and wait" strategy for rectal cancer patients after achieving a clinical complete response (cCR) following neoadjuvant chemoradiotherapy (nCRT).@*Methods@#A cross-sectional survey was used in this study. Selection of subjects: (1) Domestic public grade III A (provincial and prefecture-level) oncology hospitals or general hospitals possessing the radiotherapy department and the diagnosis and treatment qualifications for colorectal cancer. (2) Surgeons of deputy chief physician or above. Using the "Questionnaire Star" online survey platform to create a questionnaire about cognition, attitude and treatment choice of the "watch and wait" strategy after cCR following nCRT for rectal cancer. The questionnaire contained 32 questions, such as the basic information of doctor, the current status of rectal cancer surgery, the management of pathological complete remission (ypCR) after nCRT for rectal cancer, the selection of examination items for diagnosis of cCR, the selection of suitable people undergoing "watch and wait" approach, the nCRT mode for promotion of cCR, the choice of evaluation time point, the willingness to perform "watch and wait" approach and the treatment choice, and the risk and monitoring of "watch and wait" approach. A total of 116 questionnaires were sent to the respondents via WeChat between January 31 and February 19, 2019. Statistical analysis was performed using Fisher′s exact test for categorical variables.@*Results@#Forty-eight hospitals including 116 surgeons meeting criteria were enrolled, of whom 77 surgeons filled the questionnaire with a response rate of 66.4%. "Watch and wait" strategy was carried out in 76.6% (59/77) of surgeons. Seventy surgeons (90.9%) were aware of the ypCR rate of rectal cancer after preoperative nCRT and 49 surgeons (63.6%) knew the 3-year disease-free survival of patients with ypCR in their own hospitals. Fifty-five surgeons (71.4%) believed that patients with ypCR undergoing radical surgery met the treatment criteria and were not over-treated. Three most necessary examinations in diagnosing cCR were colonoscopy (96.1%, 74/77), digital rectal examination (DRE) (90.9%,70/77) and DWI-MRI (83.1%, 64/77). Responders preferred to consider a "watch and wait" strategy for patients with baseline characteristics as mrN0 (77.9%, 60/77), mrT2 (68.8%, 53/77) and well-differentiated adenocarcinoma (68.8%, 53/77). Sixty-six surgeons (85.7%) believed that long-term chemoradiotherapy (LCRT) with combination or without combination of induction and/or consolidation of the CapeOX regimen (capecitabine + oxaliplatin) should be the first choice as a neoadjuvant therapy to achieve cCR. Forty-one surgeons (53.2%) believed that a reasonable interval of judging cCR after nCRT should be ≥ 8 weeks. Forty-four surgeons (57.1%) routinely, or in most cases, informed patient the possibility of cCR and proposed to "watch and wait" strategy in the initial diagnosis of patients with non-metastatic rectal cancer. Thirteen surgeons (16.9%) would take the "watch and wait" strategy as the first choice after the patient having cCR. Fifty-two surgeons (67.5%) would be affected by the surgical method, that was to say, "watch and wait" approach would only be recommended to those patients who would achieve cCR and could not preserve the anus or underwent difficult anus-preservation surgery. Sixteen surgeons (20.8%) demonstrated that "watch and wait" strategy would not be recommended to patients with cCR regardless of whether the surgical procedure involved anal sphincter. Eleven surgeons (14.3%) believed that the main risk of "watch and wait" approach came from distant metastasis rather than local recurrence or regrowth. Twenty-nine of surgeons (37.7%) did not understand the difference between "local recurrence" and "local regrowth" during the period of "watch and wait". Twenty-six surgeons (33.8%) thought that the monitoring interval for the first 3 years of "watch and wait" strategy was 3 months, and the follow-up monitoring interval could be 6 months to 5 years. Surgeons from cancer specialist hospitals had higher approval rate, notification rate, and referral rate of "watch and wait" strategy than those from general hospitals. Thirty-one surgeons (42.5%) considered that the difficulty and concern of carrying out "watch and wait" approach in the future was the disease progress leading to medical disputes. Twenty-six surgeons (35.6%) demonstrated that their concern was lack of uniform evaluation standard for cCR.@*Conclusions@#Chinese surgeons seem to have inadequate knowledge of non-operative management for rectal cancer patients achieving cCR after nCRT and show relatively conservative attitudes toward the strategy. Chinese consensus needs to be formed to guide the non-operative management in selected patients. Chinese Watch & Wait Database (CWWD) is also needed to establish and provide more evidence for the use of alternative procedure after a cCR following nCRT.

ABSTRACT

OBJECTIVE@#To investigate the long-term outcome of organ preservation with local excision or "watch and wait" strategy for mid-low rectal cancer patients evaluated as clinical complete remission (cCR) or near-cCR following neoadjuvant chemoradiotherapy (NCRT).@*METHODS@#Clinical data of 62 mid-low rectal cancer patients evaluated as cCR/near-cCR after NCRT undergoing organ preservation surgery with local excision or receiving "watch and wait" strategy at Department of Gastrointestinal Surgery, Peking University Cancer Hospital and Institute from March 2011 to August 2017 were retrospectively analyzed. According to the approximate 1:2 pairing, 123 patients who underwent radical resection with complete pathological remission(ypCR) after neoadjuvant chemotherapy during the same period were selected for prognosis comparison. The primary endpoint of the study was 3-year non-regrowth disease-free survival (NR-DFS) and tumor specific survival (CSS). Survival analysis was performed using the Kaplan-Meier curve (Log-rank method). The secondary endpoint of the study was 3-year organ preservation and sphincter preservation.@*RESULTS@#The retrospective study included 38 male and 24 female patients. The median age was 60 (31-79) years and the median distance from tumor to anal verge was 4(1-8) cm. The ratio of cCR and near-cCR was 79.0%(49/62) and 21.0%(13/62) respectively. Local regrowth rate was 24.2%(15/62). Of 15 with tumor regrowth, 9 patients received salvage radical rectal resection and no local recurrence was found during follow-up; 4 patients received salvage local excision among whom one patient had a local recurrence occurred patient; 2 patients refused further surgery. The overall metastasis rate was 8.1%(5/62), including resectable metastasis(4.8%,3/62) and unresectable metastasis (3.2%,2/62). The valid 3-year organ preservation rate and sphincter preservation rate were 85.5%(53/62) and 95.2%(59/62) respectively. The median follow-up was 36.2(8.6-89.0) months. The 3-year NR-DFS of patients with cCR and near-cCR was 88.6% and 83.1% respectively, which was not significantly different to that of patients with ypCR (94.7%, P=0.217). The 3-year CSS of patients with cCR and near-cCR was both 100%, which was not significantly different to that of patients with ypCR(93.4%, P=0.186).@*CONCLUSIONS@#Mid-low rectal cancer patients with cCR or near-cCR after NCRT undergoing organ preservation with local excision or receiving "watch and wait" strategy have good long-term prognosis with low rates of local tumor regrowth and distant metastasis, which is similar to those with ypCR after radical surgery. This treatment mode may be used as an option for organ preservation in mid-low rectal cancer patients with good tumor remission after NCRT.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the applicable value of transanal total mesorectal excision (taTME) in male low rectal cancer patients with narrow pelvis-"difficult pelvis", which remains difficult for both open and laparoscopic sphincter-saving operations.</p><p><b>METHODS</b>Clinical data of male low rectal cancer patients diagnosed by pathology undergoing taTME between June 2016 and January 2018 at Peking University Cancer Hospital were collected. A retrospective cohort study was performed. Patients were selected according to the following criteria: (1) low rectal cancer, the distance between inferior margin of tumor and anal verge ≤5 cm; (2) the distance between two sciatic tubercles <5 cm; (3) body mass index (BMI) >25 kg/m; (4) tumor horizontal diameter ≤4 cm. Operation time, intraoperative blood loss, postoperative hospital stay, postoperative complications and anal function were analyzed.</p><p><b>RESULTS</b>A total of 20 patients were included in this study. All the patients received preoperative neoadjuvant chemoradiation and hybrid transabdominal and transanal surgery. The median BMI was 27.7(26.2-36.4) kg/m; the median distance between two sciatic tubercles was 92.5 (78-100) mm; the median distance between the inferior margin of tumor to the anal verge was 4 (2-5) cm; the median operation time was 302 (215-402) min; the median intraoperative blood loss was 100 (50-200) ml; the median postoperative hospital stay was 9 (5-15) d. Postoperative complications occurred in 5 patients (25%), including 3 pelvic infection, 1 intestinal obstruction, 1 anastomotic leakage receiving sigmoid colostomy. There was no perioperative death. Sphincter-preservation rate was 100%. Nineteen patients received anal manometry 1 month after operation with normal resting pressure (41.5±8.6) mmHg and squeeze pressure (121.0±11.6) mmHg. All the patients were followed up to March 2018, and the median follow-up time was 4.5 months. Only 1 patient had supraclavicular lymph node metastasis and no local recurrence was found.</p><p><b>CONCLUSIONS</b>The safety of transanal total mesorectal excision for male patients with low rectal cancer and difficult pelvis is acceptable.

ABSTRACT

Objective This study was to evaluate the relative applicability of serum cystatin C(Cys C)-based formulas and serum creatinine-based formulas for renal glomerular filtration rate(GFR) of Chinese children with chronic kidney disease(CKD).Methods Six hundred and nine Chinese CKD patients of less than 18 years old were enrolled from January 2011 to October 2016 in Shengjing Hospital of China Medical University.The value for estimated GFR (eGFR) was derived from using the 11 formulas,and 99mTc-DTPA renal dynamic imaging was the golden standard of standard GFR(sGFR).SPSS 22.0 statistical software was used to compare the accuracy of each assessment formula and the correlation between GFR markers(Cys C, β2-MG) and sGFR.Results A total of 609 children were enrolled,including 332 patients in CKD stage 1 (211 males and 121 females),165 patients in CKD stage 2(99 males and 66 females),70 patients in CKD stage 3(43 males and 27 females),22 patients in CKD stage 4(13 males and 9 females),and 20 patients in CKD stage 5(16 males and 4 females).All of the formulas either overestimate or underestimate GFR in chil-dren with CKD. In contrast with other formulas,CKD-EPI formula and Filler formula performed better regardless of gender and age difference.Serum β2-MG and serum Cys C all showed a negative relationship with sGFR(respectively r= -0.478 and r= -0.585,P<0.01).Conclusion CKD-EPI formula and Filler formula provide the better approximation to sGFR than other formulas in Chinese children with CKD.Howev-er,we need to try our best to enroll more patients to develop a more accurate GFR estimation formula in Chinese children.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effect of adjuvant chemotherapy on the prognosis of stage II( colon cancer patients with high risk factors.</p><p><b>METHODS</b>Clinicopathological and follow-up data of stage II( colon cancer patients undergoing radical surgery from January 2001 to March 2012 at Gastrointestinal Cancer Center of Peking University Cancer Hospital were retrospectively analyzed. The effect of adjuvant chemotherapy (within postoperative 2 month, fluorine uracil as main drugs) on the prognosis of high-risk patients was analyzed. High risk factors were defined as having at least one of the following factors: (1) tumor stage T4; (2) poor differentiation; (3) with vascular cancer embolus; (4) number of harvested lymph node less than 12; (5) complicated with obstruction or perforation.</p><p><b>RESULTS</b>A total of 497 patients with stage II( colon cancer were included in this study, of whom 258 cases(51.9%) had high risk factors, including stage T4 tumor in 80 cases(16.1%), poor differentiation in 80 cases (16.1%), cancer embolus in 37 cases (7.4%), lymph node harvested number less than 12 in 88 cases (17.7%), and obstruction or perforation in 85 cases (17.1%). Among 497 patients, number of cases with 1 to 4 high risk factors was 170 (34.2%), 68 (13.7%), 16 (3.2%) and 4 (0.8%), respectively. The last follow-up time was December 2016. The 5-year overall survival rate of all the 497 patients was 81.7%. The 5-year overall survival rate of 239 patients without high risk factors was 87.0%. The 5-year survival rate in patients with 1 to 4 risk factors was 81.9%, 73.7%, 66.7% and 25.0%, respectively (P=0.001). There was no significant difference in 5-year survival rate between 103 patients with adjuvant chemotherapy and 394 patients without adjuvant chemotherapy (79.6% vs. 82.8%, P=0.814). In patients with high risk factors, 80(31.0%) received adjuvant chemotherapy. There was no significant difference of 5-year survival rate between 80 patients with adjuvant chemotherapy and 178 patients without adjuvant chemotherapy (81.4% vs. 74.7%, P=0.147). Multivariate analysis showed that preoperative CEA level, T4 stage, lymph node harvested number, and tumor differentiation were the independent prognostic factors of patients with stage II( colon cancer (all P<0.05).</p><p><b>CONCLUSIONS</b>The proportion of patients with at least one risk factor is quite high in stage II( colon cancer cases. Adjuvant chemotherapy can not prolong the overall survival time of high risk patients.</p>

Objective Combining the concept of double loop learning in enterprise management with individualized nursing practice,the application value of this method in nursing care of patients with early onset severe preeclampsia(ESPE)was analyzed. Methods Patients with ESPE were selected from January 2014 to December 2016, which were divided into observation group and control group by random digits table method. The patients in observation group were given individualized nursing care with the idea of double loop learning,while the patients in control group received routine nursing care. The hospital admission, maternal pregnancy outcome and nursing satisfaction of the patients were compared between two groups. Results The observation group included 96 cases and the control group included 101 cases. There was no significant difference between two groups in age, gestational age, systolic blood pressure, diastolic blood pressure, and 24 hours urine protein(P>0.05).There were 87 cases of cesarean section in the observation group,while 94 cases in the control group, and there was no significant difference(P>0.05). The gestational weeks,the incidence of neonatal asphyxia,the nursing satisfaction was(35.5±2.7)weeks,5.2%(5/96), 90.6%(87/96)in the observation group and(34.1±2.0)weeks, 15.8%(16/101),72.3%(73/101)in the control group, the difference was statistically significant(t=4.149, χ2=5.843, 10.862, P<0.05 or 0.01). Conclusions In the ESPE nursing management, the individualized nursing and double loop learning can improve the child pregnancy outcomes and nursing satisfaction.

ABSTRACT

Objective To evaluate the early diagnostic value of 1,3-β-D glucan(BG) and galactomannan(GM) test for invasive fungal infections(IFI)in intensive care unit(ICU) patients.Methods From 2013 to 2015,the concentration of serum BG and GM were detected in 452 cases of ICU patients,including 182 cases with diagnosis of IFI,46 cases with possible diagnosis of IFI and 224 cases of non-IFI.The diagnostic performance of BG,GM and combined test were analyzed.Results The sensitivity,specificity,positive predictive value(PPV) and negative predictive value(NPV)of BG test were 75.0%,80.4%,75.8%,79.6%.Those of GM test were 25.80%,85.7%,59.5% and 58.7%.The sensitivity and specificity of BG and GM combined test were 87.4% and 94.7% respectively.Conclusion BG and GM combined test could improve the diagnostic efficiency,reduce the false positive rate and false negative rete,which might be helpful for the early diagnosis of IFI in ICU patients.
