ABSTRACT

This case report has described a case of papillary carcinoma of thyroglossal duct in a young male. This patient was admitted with a mass in the anterior neck for 2 years. Preoperative Bultrasonography, CT and MR showed a subcutaneous cystic mass with irregular calcification shadow in the central region of the neck without obvious enhancement. Initial diagnosis was thyroglossal duct cyst, and was excised by Sistrunk under general anesthesia. The postoperative pathological examination showed thyroglossal duct cyst combined with thyroid papillary carcinoma, which was confirmed by immunohistochemistry as thyroglossal duct papillary carcinoma.

ABSTRACT

Objective:To investigate the influences of age-adjusted Charlson comorbidity index (ACCI) on prognosis of patients undergoing laparoscopic radical gastrectomy.Methods:The retrospective cohort study was conducted. The clinicopathological data of 242 gastric cancer patients who underwent laparoscopic radical gastrectomy in 19 hospitals of the Chinese Laparoscopic Gastrointestinal Surgery Study Group-04 study, including 54 patients in Fujian Medical University Union Hospital, 32 patients in the First Hospital of Putian City, 32 patients in Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine, 31 patients in Zhangzhou Affiliated Hospital of Fujian Medical University, 17 patients in Nanfang Hospital of Southern Medical University, 11 patients in the First Affiliated Hospital with Nanjing Medical University, 8 patients in Qinghai University Affiliated Hospital, 8 patients in Meizhou People′s Hospital, 7 patients in Fujian Provincial Hospital, 6 patients in Zhongshan Hospital of Fudan University, 6 patients in Longyan First Hospital, 5 patients in the First Affiliated Hospital of Xinjiang Medical University, 5 patients in the First Hospital Affiliated to Army Medical University, 4 patients in the Second Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine, 4 patients in West China Hospital of Sichuan University, 4 patients in Beijing University Cancer Hospital, 3 patients in the First Affiliated Hospital of Xiamen University, 3 patients in Guangdong Provincial People′s Hospital, 2 patients in the First Affiliated Hospital of Xi′an Jiaotong University, from September 2016 to October 2017 were collected. There were 193 males and 49 females, aged 62(range, 23?74)years. Observation indicators: (1) age distribution, comorbidities and ACCI status of patients; (2) the grouping of ACCI and comparison of clinicopathological characteristics of patients in each group; (3) incidence of postoperative early complications and analysis of factors affecting postoperative early complications; (4) follow-up; (5) analysis of factors affecting the 3-year recurrence-free survival rate of patients. Follow-up was conducted using outpatient examination or telephone interview to detect postoperative survival of patients up to December 2020. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the nonparametric rank sum test. The X-Tile software (version 3.6.1) was used to analyze the best ACCI grouping threshold. The Kaplan-Meier method was used to calculate survival rates and draw survival curves. The Log-Rank test was used for survival analysis. The Logistic regression model was used to analyze the factors affecting postoperative early complications. The COX proportional hazard model was used for univariate and multivariate analyses of factors affecting the 3-year recurrence-free survival rate of patients. Multivariate analysis used stepwise regression to include variables with P<0.05 in univariate analysis and variables clinically closely related to prognosis. Results:(1) Age distribution, comor-bidities and ACCI status of patients. Of the 242 patients, there were 28 cases with age <50 years, 68 cases with age of 50 to 59 years, 113 cases with age of 60 to 69 years, 33 cases with age of 70 to 79 years. There was 1 patient combined with mild liver disease, 1 patient combined with diabetes of end-organ damage, 2 patients combined with peripheral vascular diseases, 2 patients combined with peptic ulcer, 6 patients combined with congestive heart failure, 8 patients combined with chronic pulmonary diseases, 9 patients with diabetes without end-organ damage. The ACCI of 242 patients was 2 (range, 0-4). (2) The grouping of ACCI and comparison of clinicopathological characteristics of patients in each group. Results of X-Tile software analysis showed that ACCI=3 was the best grouping threshold. Of the 242 patients, 194 cases with ACCI <3 were set as the low ACCI group and 48 cases with ACCI ≥3 were set as the high ACCI group, respectively. Age, body mass index, cases with preoperative comorbidities, cases of American Society of Anesthesiologists classification as stage Ⅰ, stage Ⅱ, stage Ⅲ, tumor diameter, cases with tumor histological type as signet ring cell or poorly differentiated adenocarcinoma and cases with tumor type as moderately or well differentiated adenocarcinoma, cases with tumor pathological T staging as stage T1, stage T2, stage T3, stage T4, chemotherapy cycles were (58±9)years, (22.6±2.9)kg/m 2, 31, 106, 85, 3, (4.0±1.9)cm, 104, 90, 16, 29, 72, 77, 6(4,6) in the low ACCI group, versus (70±4) years, (21.7±2.7)kg/m 2, 23, 14, 33, 1, (5.4±3.1)cm, 36, 12, 3, 4, 13, 28, 4(2,5) in the high ACCI group, showing significant differences in the above indicators between the two groups ( t=-14.37, 1.98, χ2=22.64, Z=-3.11, t=-2.91, χ2=7.22, Z=-2.21, -3.61, P<0.05). (3) Incidence of postoperative early complications and analysis of factors affecting postoperative early complications. Of the 242 patients, 33 cases had postoperative early complications, including 20 cases with local complications and 16 cases with systemic complica-tions. Some patients had multiple complications at the same time. Of the 20 patients with local complications, 12 cases had abdominal infection, 7 cases had anastomotic leakage, 2 cases had incision infection, 2 cases had abdominal hemorrhage, 2 cases had anastomotic hemorrhage and 1 case had lymphatic leakage. Of the 16 patients with systemic complications, 11 cases had pulmonary infection, 2 cases had arrhythmias, 2 cases had sepsis, 1 case had liver failure, 1 case had renal failure, 1 case had pulmonary embolism, 1 case had deep vein thrombosis, 1 case had urinary infection and 1 case had urine retention. Of the 33 cases with postoperative early complications, there were 3 cases with grade Ⅰ complications, 22 cases with grade Ⅱ complications, 5 cases with grade Ⅲa complications, 2 cases with grade Ⅲb complications and 1 case with grade Ⅳ complica-tions of Clavien-Dindo classification. Cases with postoperative early complications, cases with local complications, cases with systemic complications were 22, 13, 9 in the low ACCI group, versus 11, 7, 7 in the high ACCI group, respectively. There were significant differences in cases with postoperative early complications and cases with systemic complications between the two groups ( χ2=4.38, 4.66, P<0.05), and there was no significant difference in cases with local complications between the two groups ( χ2=2.20, P>0.05). Results of Logistic regression analysis showed that ACCI was a related factor for postoperative early complications of gastric cancer patients undergoing laparoscopic radical gastrectomy [ odds ratio=2.32, 95% confidence interval ( CI) as 1.04-5.21, P<0.05]. (4) Follow-up. All the 242 patients were followed up for 36(range,1?46)months. During the follow-up, 53 patients died and 13 patients survived with tumor. The 3-year recurrence-free survival rate of the 242 patients was 73.5%. The follow-up time, cases died and cases survived with tumor during follow-up, the 3-year recurrence-free survival rate were 36(range, 2-46)months, 29, 10, 80.0% for the low ACCI group, versus 35(range, 1-42)months, 24, 3, 47.4% for the high ACCI group. There was a significant difference in the 3-year recurrence-free survival rate between the two groups ( χ2=30.49, P<0.05). (5) Analysis of factors affecting the 3-year recurrence-free survival rate of patients. Results of univariate analysis showed that preoperative comorbidities, ACCI, tumor diameter, histological type, vascular invasion, lymphatic invasion, neural invasion, tumor pathological TNM staging, postoperative early complications were related factors for postoperative 3-year recurrence-free survival rate of gastric cancer patients undergoing laparoscopic radical gastrectomy [ hazard ratio ( HR)=2.52, 3.64, 2.62, 0.47, 2.87, 1.90, 1.86, 21.77, 1.97, 95% CI as 1.52-4.17, 2.22-5.95, 1.54-4.46, 0.27-0.80, 1.76-4.70, 1.15-3.12, 1.10-3.14, 3.01-157.52, 1.11-3.50, P<0.05]. Results of multivariate analysis showed that ACCI, tumor pathological TNM staging, adjuvant chemotherapy were indepen-dent influencing factors for postoperative 3-year recurrence-free survival rate of gastric cancer patients undergoing laparoscopic radical gastrectomy ( HR=3.65, 11.00, 40.66, 0.39, 95% CI as 2.21-6.02, 1.40-86.73, 5.41-305.69, 0.22-0.68, P<0.05). Conclusions:ACCI is a related factor for post-operative early complications of gastric cancer patients undergoing laparos-copic radical gastrectomy. ACCI, tumor pathological TNM staging, adjuvant chemotherapy are indepen-dent influencing factors for postoperative 3-year recurrence-free survival rate of gastric cancer patients undergoing laparoscopic radical gastrectomy.

The clinicopathological data of 362 gastric cancer patients undergoing neoadjuvant chemotherapy combined with radical gastrectomy in 3 medical centers, including 163 cases in Fujian Medical University Union Hospital, 141 cases in the Affiliated Hospital of Qinghai University and 58 cases in St. Mary′s Hospital, from January 2010 to December 2017 were collected. There were 270 males and 92 females, aged from 26 to 79 years, with a median age of 61 years. Of 362 patients, 304 cases in Fujian Medical University Union Hospital and the Affiliated Hospital of Qinghai University were allocated into modeling group and 58 cases in St. Mary′s Hospital were allocated into validation group. Observation indicators: (1) changes of indicators including body composition parameters, tumor markers and stress status indicators in patients in modeling group during neoadjuvant chemotherapy; (2) follow-up and survival of patients; (3) analysis of risk factor affecting prognosis of patients in modeling group; (4) construc-tion and comparison of prognostic prediction models; (5) evaluation of prognostic prediction models. Follow-up was conducted using outpatient examination, telephone interview and mail communication to detect postoperative survival of patients up to April 2021. Measurement data with normal distribution were represented as Mean± SD. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Univariate and multivariate analysis were performed using the COX proportional hazard model. The Kaplan-Meier method was used to calculate survival rates and draw survival curves. The Log-rank test was used for survival analysis. Results:(1) Changes of indicators including body composition parameters, tumor markers and stress status indicators in patients in modeling group during neoadjuvant chemotherapy: the subcutaneous adipose index, visceral adipose index, muscle index, carcinoem-bryonic antigen, CA19-9, body mass index, prognostic nutritional index and modified systemic inflammation score of 304 gastric cancer patients in the modeling group before neoadjuvant chemotherapy were 31.2 cm 2/m 2(range, 0.6?96.0 cm 2/m 2), 25.1 cm 2/m 2(range, 0.1?86.3 cm 2/m 2), 47.1 cm 2/m 2(range, 27.6?76.6 cm 2/m 2), 43.2 μg/L(range, 0.2?1 000.0 μg/L), 108.7(range, 0.6? 1 000.0)U/mL, 21.9 kg/m 2(range, 15.6?29.7 kg/m 2), 46.8(range, 28.6?69.0), 1.0±0.8, respectively. The above indicators of 304 gastric cancer patients in the modeling group before radical gastrec-tomy were 32.5 cm 2/m 2(range, 5.1?112.0 cm 2/m 2), 25.4 cm 2/m 2(range, 0.2?89.0 cm 2/m 2), 47.0 cm 2/m 2(range, 16.8?67.0 cm 2/m 2), 17.0 μg/L(range, 0.2?1 000.0 μg/L), 43.9 U/mL(range, 0.6?1 000.0 U/mL), 21.6 kg/m 2(range, 31.1?29.0 kg/m 2), 47.7(range, 30.0?84.0), 1.0±0.8, respectively. The changing value of above indicators of 304 gastric cancer patients in the modeling group during neoadjuvant chemotherapy were 1.4 cm 2/m 2(range, ?31.0?35.1 cm 2/m 2), 0.2 cm 2/m 2(range, ?23.5?32.6 cm 2/m 2), ?0.1 cm 2/m 2(range, ?18.2?15.9 cm 2/m 2), ?26.2 μg/L(range, ?933.5?89.9 μg/L), ?64.9 U/mL(range, ?992.1?178.6 U/mL), ?0.3 kg/m 2(range, ?9.7?7.1 kg/m 2), 0.9(range, ?27.1?38.2), 0.0±0.8, respec-tively. (2) Follow-up and survival of patients: 284 of 304 patients in the modeling group were followed up for 3 to 130 months, with a median follow-up time of 36 months. During follow-up, 130 cases died of tumor recurrence and metastasis and 9 cases died of non-tumor causes. The 5-year overall survival rate was 54.6%. Fifty-two of 58 patients in the validation group were followed up for 2 to 91 months, with a median follow-up time of 29 months. During follow-up, 21 cases died with the 5-year overall survival rate of 63.8%. (3) Analysis of risk factor affecting prognosis of patients in modeling group: results of univariate analysis showed that the postoperative pathological type and postoperative pathological staging were related factors affecting 5-year overall survival rate [ hazard ratio=1.685, 2.619, 95% confidence interval(CI): 1.139?2.493, 1.941?3.533, P<0.05] and 5-year progression free rate survival of 304 gastric cancer patients in the modeling group after radical gastrectomy ( hazard ratio=1.468, 2.577, 95% CI: 1.000?2.154, 1.919?3.461, P<0.05). Results of multivariate analysis showed that the postoperative pathological type and postoperative pathological staging were independent influencing factors for 5-year overall survival rate of 304 gastric cancer patients in the modeling group after radical gastrectomy ( hazard ratio=1.508, 2.287, 95% CI: 1.013?2.245, 1.691?3.093, P<0.05) and the postoperative patholo-gical staging was an independent influencing factor for 5-year progression free survival rate of 304 gastric cancer patients in the modeling group after radical gastrectomy ( hazard ratio= 2.317,95% CI: 1.719?3.123, P<0.05). (4) Construction and comparison of prognostic prediction models: the area under curve (AUC) of prognostic prediction model of subcutaneous adipose index changing value, visceral adipose index changing value, carcinoembryonic antigen changing value, CA19-9 changing value, body mass index changing value, prognostic nutritional index changing value, modified systemic inflammation score changing value for 304 gastric cancer patients in the modeling group were 0.549(95% CI: 0.504?0.593), 0.501(95% CI: 0.456?0.546), 0.566(95% CI: 0.521?0.610), 0.519(95% CI: 0.474?0.563), 0.588(95% CI: 0.545?0.632), 0.553(95% CI: 0.509?0.597), 0.539(95% CI: 0.495?0.584). The AUC of prognostic prediction model of muscle index changing value was 0.661(95% CI: 0.623?0.705) with significant differences to the AUC of prognostic predic-tion model of subcutaneous adipose index changing value, visceral adipose index changing value, carcinoembryonic antigen changing value, CA19-9 changing value, body mass index changing value, prognostic nutritional index changing value, modified systemic inflammation score changing value, respectively ( Z=3.960, 5.326, 3.353, 4.786, 2.455, 3.448, 3.987, P<0.05). The optimum cut-off value was 0.7 cm 2/m 2 for prognostic prediction model of muscle index changing. Kaplan-Meier survival curve showed there were significant differences of overall survival and progression free survival for gastric cancer patients with subcutaneous adipose index changing value <0.7 cm 2/m 2 and ≥0.7 cm 2/m 2 in the modeling group ( χ2 =27.510, 21.830, P<0.05). The nomogram prognostic prediction model was cons-tructed based on 3 prognostic indicators including muscle index change value combined with postoperative pathological type and postoperative pathological staging and the AUC of nomogram prognostic prediction model were 0.762(95% CI: 0.708?0.815) and 0.788(95% CI: 0.661?0.885) for the modeling group and the validation group, respectively. The AUC of postoperative pathological staging prognostic prediction model were 0.706(95% CI: 0.648?0.765) and 0.727(95% CI: 0.594?0.835)for the modeling group and the validation group, respectively. There were significant differences of the AUC between the nomogram prognostic prediction model of muscle index change value combined with postoperative pathological type and postoperative pathological staging and the postoperative pathological staging prognostic prediction model in the modeling group and the validation group, respectively ( Z=3.522, 1.830, P<0.05). (5) Evaluation of prognostic prediction models: the nomogram prognostic prediction model of muscle index change value combined with postoperative pathological type and postoperative pathological staging showed that patients with score of 0-6 were classified in the low risk group, patients with score of >6 and ≤10 were classified in the moderate-low risk group, patients with score of >10 and ≤13 were classified in the moderate-high risk group and patients with score of >13 were classified in the high risk group. Kaplan-Meier survival curve showed there were significant differences of the overall survival between the low risk group, moderate-low risk group, moderate-high risk group and high risk group patients in the modeling group and the validation group, respectively ( χ2 =75.276, 14.989, P<0.05). Results of decision making curve showed the nomogram prognostic prediction model of muscle index change value combined with postoperative pathological type and postoperative pathological staging had better clinical utility than the postoperative pathological staging prognostic prediction model in the modeling group and the validation group. Conclusions:The muscle index changing value of gastric cancer patient during neoadjuvant chemotherapy can be used as a prognostic indicator for gastric cancer patient prognosis after radical gastrectomy. The risk score of the nomogram prognostic prediction model of muscle index change value combined with postoperative pathological type and postoperative pathological staging can be used to evaluate the survival and prognosis of gastric cancer patients after radical gastrectomy.

ABSTRACT

Gastric cancer is one of the most common malignant tumors in the world. China is still the country with the highest incidence of gastric cancer and most patients with gastric cancer are in locally advanced stage at the first diagnosis. Traditional radical surgery combined with post-operative adjuvant treatment is difficult to further improve the prognosis of patients. In recent years, the exploration and application of neoadjuvant treatment modes such as chemotherapy, radio-therapy, targeted therapy and immunotherapy in locally advanced gastric cancer have made continuous progress. However, there is still no consensus on the benefit population, regimen options, and efficacy evaluation of neoadjuvant therapy. The authors review and comb the research progress and controversy of neoadjuvant therapy for locally advanced gastric cancer.

Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was analyzed using ANOVA. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Univariate analysis was conducted using the t test or chi-square test based on data excluding missing data of clinico-pathological and surgical data. Multivariate analysis was conducted using the Logistic regression model based on factors with P<0.20 in univariate analysis.@*Results@#There were 2 089 patients screened for eligibility, including 1 512 males, 576 females and 1 without sex information, aged (62±11)years. The body mass index (BMI) was (23±3)kg/m2. (1) The incidence of POPF after radical gastrectomy: the total incidence rate of POPF in the 2 089 patients was 20.728%(433/2 089). The incidence rates of biochemical fistula, grade B pancreatic fistula, and grade C pancreatic fistula were 19.627%(410/2 089), 1.101%(23/2 089), 0, respectively. (2) Treatment of grade B POPF after radical gastrectomy: 2 of 23 patients with grade B POPF after radical gastrectomy had drainage tube placed for more than 21 days and received anti-infective therapy. Four of 23 patients with grade B POPF after radical gastrectomy had ascites detected by imaging examination, of which 2 received peritoneal drainage guided by ultrasound, 1 received failed puncture drainage, 1 received no puncture drainage, and they were given anti-infective therapy. Eleven of 23 patients with grade B POPF after radical gastrectomy had no ascites detected by imaging examinations, and they were given anti-infective therapy and inhibitors of pancreas secretion for clinical manifestation as fever or elevated white blood cells. Six patients with no typical clinical manifestations were given somatostatin to inhibite pancreas secretion and prolonged duration of abdominal drainage tube placement (with a median time of 7 days). All the 23 patients recovered well after treatment, without reoperation. (3) Analysis of clinicopathological data: for the 2 089 patients, BMI, cases with or without neoadjuvant therapy were (23±3)kg/m2, 1 487, 160 of patients without pancreatic fistula, (23±3)kg/m2, 386, 22 of patients with biochemical fistula, and (24±3)kg/m2, 22, 1 of patents with grade B pancreatic fistula, showing significant differences between the three groups (F=5.787, χ2=8.269, P<0.05). (4) Analysis of surgical data: for the 2 089 patients, cases with open surgery, laparoscopic assisted surgery, totally laparoscopic surgery (surgical method), cases with D1 lymph lode dissection, D2 lymph lode dissection, and other lymph lode dissection (range of lymph lode dissection), cases with no omentectomy, partial omentectomy, and total omentectomy (range of omentectomy), cases with no usage of energy facility, usage of CUSA, LigaSure, LigaSure+ CUSA as energy facility, cases with or without biological glue, the number of lymph node dissection were 737, 624, 292, 24, 1 580, 51, 418, 834, 381, 63, 1 530, 23, 16, 1 431, 201, 33±14 of patients without pancreatic fistula, 146, 189, 74, 11, 389, 9, 110, 171, 128, 35, 359, 6, 9, 378, 31, 31±14 of patients with biochemical fistula, and 14, 5, 4, 0, 20, 3, 6, 13, 4, 2, 18, 1, 2, 22, 1, 37±16 of patients with grade B pancreatic fistula, showing significant differences between the three groups (χ2=15.578, 9.397, 15.023, 28.245, 8.359, F=4.945, P<0.05). (5) Risk factors for grade B POPF after radical gastrectomy: results of univariate analysis showed that usage of energy facility was a related factor for grade B POPF after radical gastrectomy (χ2=9.914, P<0.05). Results of multivariate analysis showed that laparoscopic assisted surgery, combined evisceration, application of LigaSure + CUSA, the number of lymph lode dissection were independent factors for for grade B POPF after radical gastrectomy (odds ratio=0.168, 3.922, 9.250, 1.030, 95% confidence interval: 0.036-0.789, 1.031-14.919, 1.036-82.602, 1.001-1.059, P<0.05).@*Conclusions@#The incidence of grade B POPF after radical gastrectomy is relatively low. Laparoscopic assisted surgery, combined evisceration, application of LigaSure + CUSA, and the number of lymph lode dissection are independent risk factors for grade B POPF. Trial Registration: This study was registrated at ClinicalTrial.gov in United States with the registration number of NCT03391687.

ABSTRACT

Objective:To investigate the clinical efficacy of Later-cut overlap anastomosis versus Roux-en-Y anastomosis in laparoscopic total gastrectomy.Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopathological data of 1 804 patients with gastric cancer who underwent laparoscopic total gastrectomy in Fujian Medical University Union Hospital from January 2014 to March 2019 were collected. There were 1 346 males and 458 females, aged from 18 to 91 years, with a median age of 63 years. Of 1 804 patients, 100 undergoing Later-cut overlap anastomosis for digestive tract reconstruction in totally laparoscopic total gastrectomy and 1 704 undergoing Roux-en-Y anastomosis in laparoscopic-assisted total gastrectomy were allocated into modified group and traditional group, respectively. Observation indicators: (1) the propensity score matching conditions and comparison of general data between the two groups after propensity score matching; (2) intraoperative and postoperative situations; (3) complications; (4) follow-up, including ① functional scales of European Organization for Research and Treatment of Cancer quality of life questionnaire-core 30 (EORTC-QLQ-C30) for two groups after propensity score matching, ② symptom scales of EORTC-QLQ-C30 for two groups after propensity score matching, ③ symptom scales of European Organization for Research and Treatment of Cancer quality of life questionnaire of stomach 22 (EORTC-QLQ-STO22) for two groups after propensity score matching, ④ subgroup analysis; (5) learning curve of Later-cut overlap anastomosis. Patients were followed up by outpatient examination, paying a visit, Email and telephone interview once every 3 months within postoperative 2 years and once every 6 months within postoperative 3-5 years to detect postoperative life quality up to December 2019. The propensity score matching was conducted by 1∶1 matching using the nearest neighbor method. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was done using the t test. Count data were represented as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Comparison of ordinal data between groups was analyzed using the nonparametric rank sum test. Measurement data with skewed distribution were represented as M ( P25, P75) or M (range), and comparison between groups was done using the U test. The cumulative sum curve was used to analysis minor changes between individual and overall data, with the equation of CUSUM=∑ n,i=1 ( x i- μ), x i as esophagojejunostomy time of individuals, μ as the average time of esophagojejunostomy, n as serial number of patients.

ABSTRACT

In recent years,the incidence of gastric cancer has been decreasing year by year in the world,but the incidence of adenocarcinoma of esophagogastric junction (AEG) has shown a significant upward trend,especially in western countries such as Europe and America.The prognosis of AEG is poor,therefore,it is extremely necessary to establish AEG's best diagnosis and treatment strategies to improve the long-term outcome of AEG.Nowadays,the most commonly used AEG classification is the Siewert classification proposed by German scholars in 1987,which is based on the anatomical features of the esophagogastric junction.It provides guidance for the choice of surgical methods.Compared with European and American countries,Siewert type Ⅱ or type Ⅲ are more common in Asian countries,and are mainly treated as the proximal gastric cancer.Compared with gastric tumors in other areas,AEG has obvious differences and specialities in anatomy,physiology and pathology,and there is still much controversy in the field of surgical and comprehensive treatment.

ABSTRACT

Objective To investigate the application value of indocyanine green (ICG) fluorescence imaging in lymphadenectomy of laparoscopic radical gastrectomy for gastric cancer.Methods The retrospective cohort study was conducted.The clinicopathological data of 702 patients with primary gastric cancer who underwent laparoscopic radical gastrectomy and D2 lymphadenectomy in the Fujian Medical University Uuion Hospital between April and December 2017 were collected.There were 517 males and 185 females,aged from 22 to 91 years,with an average age of 61 years.Of the 702 patients,39 using ICG fluorescence imaging in the surgery and 663 not using ICG fluorescence imaging were allocated into ICG group and non-ICG group,respectively.Observation indicators:(1) surgical situations and postoperative recovery;(2) postoperative complications;(3) average number of lymph node dissected and positive lymph nodes;(4) follow-up situations.The number of lymph node dissected in the first station (No.1-7 group) and second station (No.8-12 group) were analyzed respectively.Follow-up using outpatient examination and telephone interview was performed to detect complications of patients up to June 2018.Measurement data with normal distribution were represented as Mean±SD,comparison between groups was analyzed using the t test.Measurement data with skewed distribution were described as M (range),comparison between groups was analyzed using the Mann-Whitney U test.Count data were represented as absolute number or percentage,comparison between groups was analyzed using the chi-square test.Comparisons of ordinal data were analyzed by the Mann-Whitney U test.Results (1) Surgical situations and postoperative recovery:702 patients underwent successfully laparoscopic radical gastrectomy and D2 lymphadenectomy,without injuries of important vessels and adjacent organs,without combined multiple organs resection or conversion to open surgery.Of 39 patients in the ICG group,cases undergoing total radical gastrectomy,distal subtotal gastrectomy and proximal subtotal gastrectomy,cases with Roux-en-Y esophagojejunostomy,Billroth Ⅰ anastomosis,Billroth Ⅱ anastomosis,Roux-en-Y gastrojejunostomy and esophagogastric anastomosis,operation time,volume of intraoperative blood loss,time for out-of-bed activities,time to initial anal exsufflation,time to first fluid diet intake and duration of postoperative hospital stay were 21,16,2,21,3,13,2,0,(173±28) minutes,40 mL (range,5-200 mL),(2.1±0.6)days,(3.5±1.4)days,(4.8± 1.3)days,(8.6±3.6) days.The above indexes were 363,299,1,363,27,267,1,5,(174±41)minutes,50 mL(range,0-1 750 mL),(2.2±0.8)days,(3.4± 1.1) days,(4.6± 1.5) days,(9.4± 5.0) days in the non-ICG group.There were statistically significant differences in the surgical type and digestive reconstruction method (x2 =9.550,11.388,P< 0.05) and no statistically significant difference in the operation time,volume of intraoperative blood loss,time for out-of-bed activities,time to initial anal exsufflation,time to first fluid diet intake and duration of postoperative hospital stay (t =0.221,Z =-0.651,t =0.492,-0.826,-0.842,0.995,P>0.05).(2) Postoperative complications:92 out of the 702 patients had postoperative complications,without death of complications.The incidence of complication was 15.38%(6/39) and 12.97%(86/663) in the ICG group and non-ICG group,with no statistically significant difference between the two groups (x2=0.188,P>0.05).Six patients with complications (1 of Clavien-Dindo Ⅳ,2 of Clavien-Dindo Ⅲa,3 of Clavien-Dindo Ⅰ) in the ICG group and 86 (6 of Clavien-Dindo Ⅳ,16 of Clavien-Dindo Ⅲ,61 of Clavien-Dindo Ⅱ,3 of Clavien-Dindo Ⅰ) in the non-ICG group were cured after symptomatic treatment.(3) Average number of lymph node dissected and positive lymph nodes:the average number of lymph node dissected and positive lymph nodes was 37 (range,3-112) and 1 (range,0-68) of 702 patients,38 (range,24-70) and 2 (range,0-42) in the ICG group,37 (range,3-112) and 1 (range,0-68) in the non-ICG group,with no statistically significant difference between the two groups (Z=-1.454,-0.514,P>0.05).Stratified analysis:the average number of No.1-7 group lymph nodes dissected and positive lymph nodes was 34 (range,16-67) and 2 (0-38) in the ICG group,33 (range,3-91) and 1 (range,0-56) in the non-ICG group.The average number of No.8-12 group lymph nodes dissected and positive lymph nodes was 11 (range,4-22) and 0 (range,0-13) in the ICG group,9 (range,0-31) and 0 (range,0-25) in the non-ICG group.There was a statistically significant difference in the average number of No.8-12 group lymph nodes dissected between the two groups (Z=-1.984,P<0.05).There was no statistically significant difference in the average number of No.1-7 group lymph nodes dissected,positive No.1-7 group lymph nodes and the average number of positive No.8-12 group lymph nodes between the two groups (Z =-1.302,-0.463,-0.758,P>0.05).(4) Follow-up situations:702 patients were followed up for 6-14 months,with a median time of 10 months.There was no readmission caused by postoperative complications in the two groups.Conclusion ICG fluorescence imaging in lymphadenectomy of laparoscopic radical gastrectomy for gastric cancer is beneficial to dissection of perigastric lymph nodes and increase number of lymph nodes dissected,but cannot increase operation time and incidence of postoperative complications.

ABSTRACT

Objective To investigate the development trend,safety and clinical effects of laparoscopic radical gastrectomy (LRG) for gastric cancer.Methods The retrospective and descriptive study was conducted.The clinicopathological data of 4 435 patients with gastric cancer who underwent LRG in the Fujian Medical University Union Hospital between January 2008 and December 2017 were collected.There were 3 263 males and 1 172 females,aged (61±11)years,with a range of 12-93 years.According to the operation time,4 435 patients were divided into two periods,including 1 588 patients of the early period (2008-2012) and 2 847 patients of the later period (2013-2017).Observation indicators:(1) the clinicopathological data of patients;(2) intraoperative and postoperative situations;(3) postoperative complications;(4) follow-up and survival situations.Follow-up using outpatient examination,visit to home,mail and telephone interview was performed to detect survival of patients once every 3 months within 2 years postoperatively and once every 6 months after 2 years postoperatively up to June 2018.Survival time was from operation time to the last follow-up,death or deadline of follow-up database such as loss to follow-up or death of other diseases.Measurement data with normal distribution were represented as Mean±SD,and comparison between groups was analyzed by the t test.Measurement data with skewed distribution were represented as M (range).Count data were described as frequency or percentage,comparison between groups was analyzed using the chi-square test.Linear analysis was done using the unitary linear regression.The survival rate and survival curve were respectively calculated and drawn by the Kaplan-Meier method,and Log-rank test was used for survival analysis.Results (1) The clinicopathological data of patients:there were 3 263 males and 1 172 females of the 4 435 patients,accounting for 73.574%(3 263/4 435) and 26.426% (1 172/4 435),respectively.TNM staging of the 4 435 patients:1 133 cases were detected early gastric cancer (T1 stage) and 3 302 cases were detected advanced gastric cancer including 518,1 431,1 353 in T2,T3 and T4a stages respectively.Linear regression analysis showed a linear correlation between the cases of LRG and operation year (R2 =0.911,P<0.05) and a gradually increasing in cases of LRG.The sex

ABSTRACT

<p><b>OBJECTIVE</b>To explore the prognostic assessment value of preoperative blood platelet-lymphocyte ratio (PLR) in patients with gastric mixed adenoneuroendocrine carcinoma (gMANEC) treated with radical surgery.</p><p><b>METHODS</b>Clinical and pathological data of 84 gMANEC patients who underwent radical resection from 2006 to 2016 in Department of Gastric Surgery, Fujian Medical University Union Hospital were analyzed retrospectively. Receiver operating characteristic (ROC) curve analysis was performed to determine the cutoff value of the PLR for predicting prognosis. The Cox proportional hazards regression model was used to identify prognostic factors of gMANEC.</p><p><b>RESULTS</b>All the patients underwent D2 lymph node dissection, including 26 cases of distal subtotal gastrectomy and 58 cases of total gastrectomy. The postoperative pathological TNM stage system(pTNM) demonstrated that the patients of stage I(, II(, and III( were 9(10.7%), 14(16.7%), and 61(72.6%) cases, respectively. The median follow-up time was 40(3 to 96) months. The recurrence rate was 41.7%(35/84). The median time to recurrence was 10 (1 to 40) months, and 82.9%(29/35) patients experienced recurrence within the first 2 years after operation. The median overall survival time was 27(3 to 39) month, and the median recurrence-free survival time was 21 (1 to 96) months. The 1-, 3-, and 5-year overall survival(OS) rates were 87.6%, 56.6%, and 47.4%, respectively, and the 1-, 3-, and 5-year recurrence-free survival (RFS) rates were 70.5%, 50.7%, and 44.9%, respectively. The best cutoff value of the PLR for predicting prognosis was 133 through ROC curve, which categorized all the patients into low PLR group (≤133) comprising 28 patients and high PLR group (>133) comprising 56 patients. The tumor recurrence rate was significantly higher in high PLR group (50.0%, 28/56) than that in low PLR group(25.0%, 7/28)(P=0.028). The live metastasis rate was significantly higher in high PLR group(35.7%, 20/56) than that in low PLR group(10.7%, 3/28)(P=0.015). Cox regression analysis showed that only pTNM stage (P=0.003) was independent prognostic factors of OS, while both pTNM stage (P=0.000) and blood PLR (P=0.015) were independent prognostic factors of RFS.</p><p><b>CONCLUSION</b>gMANEC patients with high preoperative PLR tend to present recurrence and metastasis, especially to present live metastasis, so they should be kept under surveillance more frequently after surgery.</p>

These patients were divided into favorable site group (F group, 90 cases), including gastric fundus, anterior wall and greater curvature of gastric body, and unfavorable site group (UF group, 43 cases),including gastroesophageal junction, posterior wall and lesser curvature of gastric body,antrum and pylorus, according to the 2014 version National Comprehensive Cancer Network Clinical Guidelines. Short-term and long-term efficacy between the two groups was compared.</p><p><b>RESULTS</b>There were no significant differences between the two groups in the general clinicopathological parameters (all P>0.05). The operation time of F group and UF group was (107.3±52.3) min and (119±53.4) min respectively (P=0.21). The blood loss in F group and UF group was (35.2±34.2) ml and (35.2±31.2) ml respectively (P=1.00). In addition, there were no significant differences in time to first fluid diet, time to first flatus, postoperative hospital stay and hospitalization expenses between the two groups(all P>0.05). In F group and UF group, morbidity of postoperative complication was 6.7%(6/90) and 4.7%(2/43) respectively (P=0.72), morbidity of category I(-II( complication was 4.4%(4/90) and 2.3%(1/43) respectively (P=0.66),and morbidity of category III(-IIII( complication was 2.2%(2/90) and 2.3% (1/43) respectively (P=1.00).

ABSTRACT

<p><b>OBJECTIVE</b>To explore the feasibility and efficacy of laparoscopic D2 radical gastrectomy in patients with gastric neuroendocrine carcinoma (GNEC).</p><p><b>METHODS</b>Clinical data of 84 patients with GNEC undergoing laparoscopic D2 radical gastrectomy in Union Hospital from January 2006 to December 2012 were analyzed respectively. Among these patients, 44 cases underwent laparoscopic D2 gastrectomy (LAG group) and 40 cases underwent open gastrectomy (OG group). The short- and long-term outcomes, 3-year survival and recurrence-free survival were compared between two groups.</p><p><b>RESULTS</b>The LAG group and OG group did not differ significantly in terms of clinicopathologic characteristics. All the patients completed operations successfully and no patients in the LAG group ware converted to laparotomy. The operative time was similar (P>0.05). As compared to OG group, LAG group had less intra-operative blood loss [(85±21) ml vs. (192±89) ml, P=0.003], lower ratio of transfusion [2.3%(1/44) vs. 15.0%(6/40), P=0.048], shorter time to ambulation after surgery [(2.5±1.1) days vs. (3.5±1.1) days, P=0.001], faster postoperative gastrointestinal function recovery [(2.9±1.1) days vs. (5.1±1.0) days, P=0.001], shorter time to resume soft diet [(4.1±1.2) days vs. (5.7±1.3) days, P=0.001] and shorter postoperative hospital stay [(12.0±3.4) days vs. (15.0±5.5) days, P=0.002]. No significant difference was observed in average dissected lymph node number between LAG and OG group (35.0±16.4 vs. 31.6±12.1, P=0.204). Morbidity of postoperative complication of LAG group and OG group was 11.4%(5/44) and 17.5%(7/40) respectively (P=0.422). The overall 3-year survival rate was 54.0% for all the patients, while 3-year survival rate was 56.3% in LAG group and 51.4 % in OG group (P=0.478).

ABSTRACT

A good team work including an excellent assistant is very important for laparoscopic radical gastrectomy, because of the complex anatomy around the stomach and the difficulty of extra-gastric lymphadenectomy. An assistant with expert cooperation can shorten the operation time, decrease bleeding, increase the smoothness of the operation, improve the quality of surgery. Growth of assistants requires time and case accumulation. Firstly they should understand their own tasks, perfect themselves in the use of laparoscopic instruments and operating skills. A good assistant should follow the lead of the surgeon and maintain good cooperation, and keep on learning in order to shorten the learning curve.

ABSTRACT

<p><b>BACKGROUND</b>Little is known about the feasibility and safety of laparoscopy-assisted total gastrectomy (LATG) with extended lymphadenectomy in patients with advanced gastric cancer (AGC). This study compared the technical feasibility, safety, and oncologic efficacy of LATG with open total gastrectomy (OTG) for AGC without serosa invasion.</p><p><b>METHODS</b>From January 2009 to December 2011, 235 patients underwent LATG and 153 patients underwent OTG for AGC without serosa invasion. Age, gender, and depth of invasion (pT2 and pT3) were matched by propensity scoring, and 116 patients (58 LATG and 58 OTG) were selected for analysis. Their clinicopathologic characteristics, postoperative outcomes, and survival were compared.</p><p><b>RESULTS</b>There was no significant difference in clinicopathologic characteristics between the two propensity-matched groups. Median number of lymph nodes per patient was 29, and the mean number of retrieved lymph nodes was similar in the LATG and OTG groups (30.8±10.2 vs. 29.0±8.3). Peri-operative characteristics, operation time, number of transfused units per patient, and time to resumption of activities were similar in the two groups; while blood loss, times to first flatus and resumption of soft diet, and post-operative stay were significantly lower in the LATG group (P < 0.05, respectively). Rates of post-operative complications (12.1% vs. 15.5%) and postoperative mortality (0% vs. 1.7%), as well as cumulative survival rates, were similar.</p><p><b>CONCLUSIONS</b>LATG with D2 lymphadenectomy is a safe and feasible procedure for AGC patients without serosa invasion. Prospective, multicenter, randomized trials are needed to confirm the efficacy of LATG in this patient population.</p>
