ABSTRACT
The combination of standardized D2 lymph node dissection and lymph node sorting after surgery can improve the survival of patients with gastric cancer and increase the accuracy of staging. With the development of different lymphatic tracers, individualized lymphatic navigation has become a new technical breakthrough in minimally invasive surgery for gastric cancer. Lymph node tracing is an important method to improve the quality of intraoperative lymph node dissection and correct the postoperative pathological stage. This article reviews the application status and progress of lymphatic navigation technology.
ABSTRACT
Objective:To evaluate the efficacy and safety of total aortic arch replacement in elderly patients with Stanford type A aortic dissection(TAAD).Methods:In this retrospective study, a total of 481 TAAD patients treated with total arch replacement in our hospital from January 2016 to January 2020 were divided into three groups: aged≤59 years, 60-69 years and ≥70 years.The differences between three groups in surgical method, extracorporeal circulation time, blocking time, circulatory time, stopping time, surgical time, ventilator use time, ICU time, hospitalization time, treatment rate of continued renal replacement, fatality rate, and cause of death were statistically analyzed and compared.Results:There were statistically significant differences in the stopping time between any two groups of the three groups(all P<0.05). The older the age, the shorter the circulatory arrest time.The difference of ventilator time and ICU time between ≤59 and 60-69 years was statistically significant( P<0.01). Patients with continuous renal replacement(CRRT)were 19.0%(71/373)in ≤59 years, 23.1%(18/78)in 60~69 years, and 26.7%(8/30)over 70 years.In-hospital mortality was 35/373(9.4%)in the group of ≤59 years old, 11/78(14.1%)in the group of 60~69 years old, and 5/30(16.7%)in the group of ≥70 years old.There was no death in patients undergoing type Ⅱ hybrid surgery. Conclusions:Age is one of the important death factors after total aortic arch replacement in TAAD patients.Total aortic arch replacement is an acceptable surgical method for elderly patients with TAAD.Hybridization may reduce hospitalization death in elderly patients.
ABSTRACT
Objective:To investigate the influence of different injection time of carbon nanoparticle tracer on the acquisition of lymph nodes in adenocarcinoma of esophagogastric junc-tion (AEG) treated by neoadjuvant chemoradiotherapy (nCRT) combined with surgical resection.Methods:The prospective randomized controlled study was conducted. The clinicopathological data of 120 AEG patients who were treated by nCRT combined with surgical resection in the Fourth Hospital of Hebei Medical University from March 2020 to March 2021 were selected. Based on random number table, patients were allocated into two groups. Patients undergoing endoscopic injection of carbon nanoparticle tracer 24 hours before nCRT were allocated into the experiment group, and patients undergoing endoscopic injection of carbon nanoparticle tracer 24 hours before surgical resection were allocated into the control group. All patients received the same plan of nCRT combined with D 2 radical gastrectomy. Observation indicators: (1) grouping situations of the enrolled patients; (2) surgical and postoperative pathological situations; (3) postoperative complications and treatment. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the independent sample t test. Measurement date with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test. Comparison of ordinal data was analyzed using the non-parameter rank sum test. Results:(1) Grouping situations of the enrolled patients. A total of 120 patients were selected for eligibility. There were 85 males and 35 females, aged (60±9)years. There were 60 patients in the experiment group and 60 patients in the control group, respectively. (2) Surgical and postoperative pathological situations. Patients in the two groups underwent D 2 radical gastrectomy successfully, with R 0 resection. The number of lymph nodes harvest, the number of lymph nodes stained, the number of metastatic lymph nodes stained, the number of micro lymph nodes, the number of inferior mediastinal lymph nodes, the number of inferior mediastinal lymph nodes stained, cases in postoperative pathological stage N0, stage N1, stage N2, stage N3a were 40.6±13.9,20.1±7.7, 1.0(0,3.0), 8.1±2.8, 3.7±1.3, 2.0(1.0,2.0), 18, 13, 23, 6 in patients of the experiment group, respectively. The above indicators were 30.4±8.3, 12.7±3.5, 0(0,1.0), 6.2±2.0, 2.4±1.2, 1.0(0,1.0), 23, 21, 15, 1 in patients of the control group, respectively. There were significant differences in the above indicators between the two groups ( t=-5.01, 6.85, Z=-3.78, t=-4.04, -5.57, Z=-5.48, -2.12, P<0.05). (3) Postoperative complications and treatment. There were 5 cases of the experiment group and 7 cases of the control group with postoperative complications, showing no significant difference between the two groups ( χ2=0.37, P>0.05). The patients with postoperative complications were improved after symptomatic treatment. Conclusion:Compared with injection of carbon nanoparticle tracer 24 hours before surgical resection, injection of carbon nanoparticle tracer 24 hours before nCRT can improve the acquisition of lymph nodes in AEG treated by nCRT combined with surgical resection.

Pathology showed gastrointestinal stromal tumor in 11 cases, leiomyoma in 5 cases and schwannoma in 2 cases. All were with negative margins. The average tumor diameter was (4.7±1.4) cm. The median follow-up time was 16.5 months, and there was no sign of tumor recurrence or metastasis.Conclusion:The serosa muscular layers circumferential incision combined with mucosal layer cutting and closure technique in laparoscopic or robotic surgery is a safe and feasible procedure for treating gastrointestinal mesenchymal tumor at difficult sites of the stomach.
ABSTRACT
Objective To investigate the clinicopathological characteristics and prognosis of patients with Borrmann type Ⅳ gastric cancer. Methods A cohort retrospective analysis of 2386 patients with gastric cancer who underwent radical surgery was used to screen out Borrmann type Ⅳ patients, and analyze their clinical features and prognostic factors. Results Among 2386 patients with gastric cancer, 363 cases (15.21%) were Borrmann type Ⅳ. Compared with non-Borrmann type Ⅳ gastric cancer patients, Borrmann type Ⅳ patients had higher rates of simultaneous liver metastasis, metachronous liver metastasis, lymph node metastasis and vascular infiltration. Moreover, the age of onset tended to be younger and the pathological type tended to be poorly differentiated-undifferentiated (all P < 0.05). The 5-year OS of the entire group was 49.32% and the 5-year DFS was 44.61%. There were significant differences in 5-year OS and DFS between Borrmann type Ⅳ and non-Borrmann type Ⅳpatients (all P < 0.001). The subgroup analyses showed that there were statistically significant differences in 5-year OS and DFS of gastric cancer patients between Borrmann type Ⅳ and non-Borrmann type Ⅳ in pT2-pT4a and pN0-pN3a stages (all P < 0.005). Multivariate analysis showed that the poorly differentiated-undifferentiated tumor, the T4a-pT4b stage of tumor invasion depth, lymph node metastasis, the ⅢA-ⅢC pTNM stage of the tumor, postoperative liver metastasis and peritoneal metastasis were independent risk factors affecting the prognosis of Borrmann type Ⅳ gastric cancer patients (all P < 0.05). Conclusion Borrmann type Ⅳ gastric cancer is prone to liver metastasis, lymph node metastasis, peritoneal metastasis and poor prognosis, and it's prognosis is affected by a variety of independent risk factors.
ABSTRACT
Objective:To investigate the clinical value of systemic immune-inflammation index (SII) based on peripheral blood neutrophils, lymphocytes and platelets counts in predicting the prognosis of patients with gastric cancer after radical resection.Methods:From January 1, 2012 to January 1, 2015, the data of 2 273 patients with gastric cancer who underwent radical surgery at the Third Department of Surgery of the Fourth Hospital of Hebei Medical University were retrospectively analyzed. SII value was calculated according to the formula (SII=neutrophil cell count (×10 9/L)×platelet cell count (×10 9/L)/lymphocyte count (×10 9/L)). According to receiver operating characteristic curve (ROC), the optimal cut-off value of SII was determined and the patients were divided into high SII group and low SII group. Chi-square test was used to compare the clinicopathological characteristics and prognosis of the two groups. Kaplan-Meier method was applied to draw survival curve, log-rank test was used for univariate survival analysis, and Cox regression model was used for multivariate survival analysis. The ROC of preoperative SII, pathological TNM stage and their combination for predicting prognosis and recurrence were drawn, and the area under the curve (AUC) values were calculated to compare the predictive power of the three. Results:According to the ROC, the optimal cut-off value of SII was 589.5, and there were 1 180 cases (51.91%) in the high SII (SII≥589.5) group and 1 093 cases (48.09%) in the low SII (SII<589.5) group. Compared with those of the low SII group, the maximum diameter of gastric cancer in the high SII group was mostly ≥5 cm (49.04%, 536/1 093 vs. 56.27%, 664/1 180), the histological types were mostly poorly differentiated to undifferentiated (55.63%, 608/1 093 vs. 61.19%, 722/1 180), the depth of tumor invasion was mainly from T4a to T4b (45.11%, 493/1 093 vs. 54.837%, 647/1 180), and the rate of lymph node metastasis, pathological TNM stage, rate of vascular infiltration, incidence of nerve invasion, Ki-67 expression level, serum carcinoembryonic antigen level and carbohydrate antigen 19-9 level in the high SII group were all higher than those in the low SII group (67.70%, 740/1 093 vs. 80.68%, 952/1 180; 57.64%, 630/1 093 vs. 71.10%, 839/1 180; 55.54%, 607/1 093 vs. 67.03%, 791/1 180; 53.89%, 589/1 093 vs. 64.32%, 759/1 180; 45.29%, 495/1 093 vs. 56.69%, 669/1 180; 56.91%, 622/1 093 vs. 63.20%, 734/1 180; 53.25%, 582/1 093 vs. 57.97%, 684/1 180), and the differences were statistically significant ( χ2=8.842, 11.097, 7.225, 21.467, 50.200, 44.984, 31.687, 25.594, 29.549, 6.612 and 5.119, all P<0.05). The 5-year overall survival rate and disease-free survival rate of the low SII group were 75.66% and 67.61%, respectively, which were both higher than those of the high SII group, (24.92% and 23.31%, respectivily), the differences were statistically significant ( χ2=620.700 and 413.00, both P<0.01). The results of multivariate Cox regression analysis showed that tumor histological type, depth of invasion, pathological TNM stage, vascular invasion and preoperative SII were independent risk factors for postoperative prognosis and recurrence of patients with gastric cancer (odds ratios were 4.126, 2.255, 5.123, 3.826, 6.126, 4.683, 2.472, 5.224, 4.416, 6.212, respectively; 95% confidence interval 2.123 to 9.721, 1.632 to 7.427, 3.325 to 10.211, 2.321 to 9.322, 4.127 to 13.782, 2.561 to 9.418, 1.322 to 6.289, 3.315 to 11.526, 2.213 to 9.382, 4.474 to 13.541; all P<0.05). The predictive power of preoperative SII (AUC=0.842, 0.815) and pathological TNM stage (AUC=0.881, 0.827) for the 5-year overall survival and disease-free survival of patients with gastric cancer after radical resection was similar, however the predictive power of combination of the two (AUC=0.943, 0.895) was higher than that of preoperative SII and pathological TNM stage alone. Conclusions:Preoperative SII is an independent risk factor for the prognosis of patients with gastric cancer after radical resection, combined with parthological TNM stage can be used as an indicator to predict the prognosis and recurrence of patients.

ABSTRACT
Objective:To investigate the risk factors of pancreatic fistula after radical resection of gastric cancer, and to establish a risk prediction scoring model for pancreatic fistula.Methods:The clinico-pathological data of 312 patients with gastric cancer admitted to the Fourth Hospital of Hebei Medical University from January 2019 to January 2020 were retrospectively analyzed. Multiple factor logistic regression model was used to analyze the risk factors of pancreatic fistula after radical resection of gastric cancer, and a risk prediction scoring model based on the risk factors was established. Hosmer-Lemeshow test was used to detect the goodness of fit of regression equation, and receiver operating characteristics (ROC) curve was used to evaluate the distinction degree of regression equation.Results:Among 312 patients with gastric cancer, 27 cases (8.65%) had pancreatic fistula after radical resection of gastric cancer. Multiple factor logistic regression analysis showed that male patients ( OR = 5.312, 95% CI 1.532-18.420, P = 0.008), age ≥ 60 years old ( OR = 4.928, 95% CI 1.493-16.250, P = 0.009), preoperative diabetes mellitus ( OR = 3.062, 95% CI 1.091-8.589, P = 0.034), lesion location in the gastric body-gastric antrum ( OR = 3.121, 95% CI 1.052-9.251, P = 0.040), intraoperative omental bursa resection ( OR = 6.209, 95% CI 2.084-18.478, P = 0.001), intraoperative lymph node dissection at D2+ station ( OR = 3.114, 95% CI 1.044-9.281, P = 0.042), intraoperative combined organ resection ( OR = 5.063, 95% CI 1.473-17.400, P = 0.010), preoperative TNM stage Ⅲ ( OR = 4.973, 95% CI 1.189-20.792, P = 0.028) were independent risk factors for pancreatic fistula after radical resection of gastric cancer. A risk prediction equation of pancreatic fistula after radical resection of patients with gastric cancer was established: P = -8.619+1.670X 1+1.595X 2+1.119X 3+1.138X 4+1.826X 5+1.136X 6+1.622X 7+1.604X 8; factor X was set as a binomial assignment (0 or 1); X1-X8 were listed as follows respectively: gender (the male was 1), age (≥60 years old was 1), preoperative diabetes history (yes was 1), lesion location (gastric body-gastric antrum was 1), intraoperative resection of omental bursa or not (yes was 1), intraoperative lymph node dissection at D2+ station or not (yes was 1), intraoperative combined organ resection or not (yes was 1), preoperative TNM stage (stage Ⅲ was 1). The goodness of fit of regression equation was high ( P = 0.395). The area under the curve of ROC by using risk prediction scoring model to judge pancreatic fistula was 0.916 (95% CI 0.872-0.960, P<0.01). The probability of pancreatic fistula in patients with score ≥ 5 was 40.90%, and the probability of pancreatic fistula in patients with score < 5 was 3.35%. Conclusions:The occurrence of pancreatic fistula after radical resection of gastric cancer is closely related to a variety of risk factors. By establishing a risk prediction scoring model for pancreatic fistula after radical resection of gastric cancer, it is helpful to effectively identify patients with high risk of pancreatic fistula after radical surgery during the perioperative period.
ABSTRACT
Objective:To investigate the clinically relevant factors of progressive disease (PD) after neoadjuvant therapy for locally advanced gastric cancer.Methods:From Jun 2011 to Mar 2016, 569 patients with locally advanced gastric cancer(cT3/4N0/+ M0) admitted to the Fourth Hospital of Hebei Medical University were retrospectively analyzed .Results:All 569 patients completed neoadjuvant therapy, 59 patients (10.4%) had PD. Univariate analysis showed that tumor size (χ 2=10.091, P=0.001), pathological type (χ 2=4.110, P=0.043), Borrmann type (χ 2=91.941, P=0.001), pre-treatment cT stage (χ 2=7.980, P=0.005) were associated with PD after neoadjuvant therapy for gastric cancer. The results of multi-factor regression analysis showed that pathological type, Borrmann type, pre-treatment cT stage were independent factors influencing the occurrence of PD after neoadjuvant therapy for advanced gastric cancer. The overall survival and progression-free suruival time of patients with PD is significantly shorter than that of patients without PD . Conclusion:The pathological type, Borrmann typing and pre-treatment cT stage are the influencing factors for the occurrence of PD after neoadjuvant treatment in advanced gastric cancer, and the prognosis of PD patients is poor.
ABSTRACT
Objective:To explore the clinico-pathological characteristics and risk factors affecting prognosis in elderly patients with gastric cancer.Methods:A retrospective study was used to retrospectively analyze 2386 patients with gastric cancer undergoing radical surgery in Surgery Department of the Fourth Hospital of Hebei Medical University from 1 January 2012 to 1 January 2015.Patients aged 70 years and older were screened so as to analyze clinical characteristics and influencing factors for the prognosis.Results:A total of 2386 patients with gastric cancer were divided into the elderly group aged 70 years and older(342 of 2386 cases, 14.3%). There were statistically significant differences between the two groups in gender, number of concomitant diseases, NRS2002 score, PG-SGA score, tumor location, tumor diameter, histological type, Borrmann classification, tumor invasion depth staging(pT), lymph node metastasis staging(pN), the anatomic extent of tumor staging(TNM, pTNM), and Lauren classifications( P<0.05). The 981 of 2386 cases(41.4%)had postoperative complications, accompanied by 413 cases(17.3%)of surgery-related complications and 568 cases(24.0%)of non-surgery-related complications.A multivariate logistic analysis showed that the number of preoperative co-existing diseases ≥ 2 was an independent influencing factor for postoperative complications in elderly gastric cancer patients( HR=4.478, 95% CI: 1.121-7.918, P=0.006). The 5-year OS and DSS was 21.10% and 62.73% in the ≥70 years gastric cancer group, and was 54.1% and 70.0% in the <70 years gastric cancer group, respectively.The difference in the 5-year OS between the two groups was statistically significant( P<0.05), while the difference in the 5-year DSS between the two groups was not statistically significant( P>0.05). Multivariate analysis by the Cox proportional hazard model showed that the independent risk factors for the prognosis of elderly patients with gastric cancer included the low-undifferentiated histological type of the tumor( P=0.004), the depth of tumor invasion pT stage of pT4a-pT4b( P=0.007), lymph node metastasis( P=0.034), tumor pTNM stage ⅢA-ⅢC( P=0.002)and vascular tumor thrombus( P=0.034). Conclusions:Elderly patients with gastric cancer have many preoperative co-existing diseases, which increases the risk of postoperative non-surgical complications.Therefore, we should focus on the peri-operative management of their comorbid diseases so as to improve the safety and efficacy of surgery.The advanced age is not the independent risk factors for the prognosis.
ABSTRACT
Objective:To investigate the treatment strategies for the thoracic endovascular aortic repair (TEVAR) of Stanford type B aortic dissection (TBAD) accompanied with intra-or post-operational retrograde type A aortic dissection (RAAD).Methods:TBAD patients who underwent TEVAR in Henan Provincial People′s Hospital from February 2004 to January 2020 were retrospectively analyzed. Among 1 176 cases, 14 cases (1.2%) were accompanied with RAAD. Another 9 patients who received TEVAR at other hospitals with TBAD accompanied with RAAD were also collected. In total 23 patients [18 males and 5 females, age as (54±12) years old , ranging from 38 to 79] were included in this study. There were 15 cases of typical dissection, 7 cases of intramural haematoma, and 1 case of penetrating aortic ulcer. Sixteen patients received surgical operation, 1 received hybrid surgery, and the remaining 6 patients underwent conventional therapies. The clinical data and followed up data were collected and analyzed.Results:Among 23 cases, 2 RAAD cases were discovered during the TEVAR, 8 cases were discovered during the perioperative period, 5 cases were discovered within 3 months after discharge, and 8 cases were discovered at more than 1 year after TEVAR, with the longest time point of 120 months after TEVAR. The RAAD rupture was located on the greater curvature side of the aorta in 21 cases, and on the minor curvature side in 2 cases. In 13 cases, the rupture was close to the stent head, and in 10 cases, the rupture was located on the ascending aorta and more than 2 cm from the stent head. Followed up data were collected in 21 cases, with the mean follow-up time as (59±40) months, ranging from 1 to 134 months. Six patients died, with 3 cases of all-reason death and 3 cases of cardiac-reason death. Among the 16 patients receiving surgical operation, one patient died during the perioperative period, and 1 patient suffered from the cerebral infarction and mediastinal infection. Well recovery was found in 1 patient received the hybrid operation. Five of 6 patients who received the conventional treatment died.Conclusions:RAAD is a serious complication related to TEVAR, with low incidence and high mortality rate. RAAD can occur in the early or late stages of TEVAR. TEVAR-associated RAAD has poor therapeutic outcomes, and the surgical operation should be recommended as the preferred treatment for RAAD in clinical practice.
ABSTRACT
@#Objective To summarize the clinical feature and treatment experience of patients with acute type A aortic dissection involving coronary arteries. Methods The clinical data of 107 patients with acute type A aortic dissection involving coronary arteries, who received operation between June 5, 2012 and December 31, 2019 in our hospital, were analyzed retrospectively. There were 80 males and 27 females at age of 24-83 (49.8±11.2) years. Results The right coronary artery was involved in 65 patients, the left in 17 patients, and both coronary arteries in 25 patients. There were 48 (44.9%) patients undergoing coronary artery bypass grafting, 49 (45.8%) patients undergoing coronary artery plasty. Fifteen patients died 30 d after the operation, with a mortality rate of 14.0%. Patients with preoperative cardiogenic shock and postoperative acute renal failure had increased risk of death (P<0.05). Eighty-two (88.2%) patients were followed up for 2 to 71 months, and 1 patient had sudden cardiac death during the follow-up period. Conclusion Acute type A aortic dissection with coronary involvement is associated with high misdiagnosis rate and mortality rate. Taking proper strategies for surgical treatment of involved coronary arteries based on precise diagnosis may improve the prognosis of patients.
ABSTRACT
OBJECTIVE@#To investigate the role of pharmacist-led anticoagulation monitoring service for warfarin anticoagulation therapy in patients during hospitalization.@*METHODS@#We retrospectively analyzed the data of 421 patients receiving warfarin anticoagulation therapy during hospitalization between April, 2016 and December, 2017. Of these patients, 316 received daily pharmacist-led anticoagulation monitoring service including checking the patients' International Normalized Ratio (INR) and other pertinent laboratory test results and reviewing medication changes and the patients' clinical status (monitoring group); the other 105 patients receiving warfarin anticoagulation therapy without pharmaceutical care served as the control group. The data including compliance rate of anticoagulant indicators, incidence and rate of prompt management of INR alert, thrombosis and bleeding events during hospitalization were analyzed among these patients.@*RESULTS@#Compared with the control patients, the patients in the monitoring group showed a significantly higher percentage time within target INR range [(73.20±9.46)% (46.32±17.11)%, < 0.001] and a higher qualified rate of INR before discharge (98.42% 60.95%, < 0.001) as well as a higher proper INR-monitoring frequency (97.15% 66.67%, < 0.001). The patients in the monitoring group showed a significantly lower incidence of INR alert than the control patients (8.23% 20.00%, < 0.001) with also a much higher rate of prompt management (96.15% 33.33%). The two groups had similar incidences of clinical events except that the control group reported a higher incidence of minor bleeding episodes (9.52% 2.53%, =0.005).@*CONCLUSIONS@#Pharmacist-led anticoagulation monitoring service can significantly improve the effectiveness and safety of warfarin anticoagulation therapy for patients during hospitalization.

Objective:To explore the clinicopathological features and prognostic factors of gastric cancer patients with pathological stage T1N3M0 (pT1N3M0) according the TCC staging criteria of the 8th edition of UICC.Methods:We retrieved the clincal data from the Third Department of Surgery, the Fourth Hospital of Hebei Medical University from 2010 to 2019 for pT1N3M0 patients, and analyzed the clinical and pathological characteristics affecting the prognosis.Results:A total of 110 pT1N3M0 gastric cancer patients were recruited, including 27 cases (24.5%) at pT1aN3aM0 stage, 10 cases (9.1%) of pT1aN3bM0, 45 cases (40.9%) of pT1bN3aM0, and 28 cases (25.5%) of pT1bN3bM0. Tumors were located in the cardia-gastric fundus in 51 cases (46.4%), in body antrum in 59 cases (53.6%); In 40 cases (36.4%) with lesion diameter ≥2cm, in 70 cases (63.6%) the lesion<2 cm; 59 cases (53.6%) were with high-medium differentiated adenocarcinoma, 51 cases (46.4%) with low undifferentiated adenocarcinoma. 104 patients (94.5%) were followed up. The 2-year overall survival rate (OS) was 63.5%, and the 2-year disease-free survival rate (DFS) was 57.7%. Counting seperately the 2-year OS was 92.0%, 50.0%, 70.7%, and 30.8%; and the 2-year DFS was 88.0%, 41.7%, 65.9%, and 23.1%, respectively in the 4 respective groups. The differences in 2-year OS and DFS between the groups were statistically significant (all P<0.05). Univariate analysis showed that the patient′s age, tumor diameter, infiltration depth (T stage), histological type, lymph node metastasis (N stage), tumor marker CA19-9, CA72-4, tumor vascular thrombus and nerve invasion, Ki67 and Lauren classification were related to the prognosis (all P<0.05). Multivariate analysis showed that tumor size≥ 2cm ( P=0.003), poor tumor tissue type ( P=0.004), N3b stage ( P=0.000), tumor vascular thrombus ( P=0.001) and nerve invasion ( P=0.002) is an independent risk factor affecting the prognosis of pT1N3M0 gastric cancer patients. Conclution:Patients with pT1N3M0 stage gastric cancer have a poor prognosis, and the N3b stage is an independent risk factor affecting the prognosis.
ABSTRACT
Objective:To explore the exfoliative value of multi-slice CT (MSCT) on conversion therapy of gastric cancer patients with positive evaluation cytology (P 0CY 1) . Methods:A total of 36 P 0CY 1 gastric cancer patients receiving conversion therapy in a prospective, single-center, phase Ⅱ clinical trial were enrolled. MSCT examinations were performed before and after conversion therapy. Its solid tumor efficacy evaluation criteria (response evaluation criteria in solid tumors, Recist) 1.1 score and tumor volume reduction rate were evaluated. The Spearman correlation test was used to analyze the correlation between Recist 1.1 score and tumor volume reduction rate and the results of conversion therapy. The ROC curve was used to determine the defined value of the volume reduction rate to identify the effectiveness of conversion therapy, and formulate new grading standards. Results:According to the conversion of free cancer cells in the abdominal cavity , 15 of 36 patients had successful conversion therapy and 21 had failed. The rate of tumor volume reduction in the successful and failed conversion groups was 44.38%±37.86% and -54.96%±156.92%, respectively( P=0.016). The Recist 1.1 score was moderate correlated with the results of conversion therapy ( R=0.540, P=0.001), and the rate of tumor volume reduction was significantly correlated with the results of conversion therapy ( R=0.657, P<0.001). When the tumor volume reduction rate of 26.27% was used as the effective threshold for evaluating conversion therapy, the AUC under the ROC curve was the largest, and the sensitivity and specificity were 80.0% and 85.7%, respectively. Conclusion:Both the MSCT-measured Recist 1.1 score and the tumor volume reduction rate can be used to evaluate the efficacy of conversion therapy in patients with pure exfoliated cytology-positive gastric cancer, and CT tumor volume measurement significantly correlates with conversion therapy results.
ABSTRACT
Objective@#To evaluate the efficacy of chemotherapy and estimate the prognosis of patients with progressive gastric cancer.@*Methods@#A total of 116 patients from a prospective, multicenter, open-label, and randomized phase Ⅲ clinical trial were enrolled in the Fourth Hospital of Hebei Medical University from Dec 2012 to Jun 2015. Pre- and two weeks after neoadjuvant chemotherapy, multi-slice spiral CT was performed to calculate the percentage change of the longest diameter and tumor volume to evaluate the Recist score and tumor volume reduction rate. Spearman correlation test was used to analyze the correlation of post-volume reduction rate, Recist 1.1 score, and tumor regression grade. The ROC curve was used to find a defined value for the volume reduction rate that identifies the effectiveness of chemotherapy and assign a new grading standard. The survival curve was drawn by Kaplan-Meier method, and the relationship between the effective survival group and the ineffective group under the new grading standard was observed.@*Results@#The Recist score was moderately correlated with the pathological tumor regression scale, and the volume reduction rate after chemotherapy was strongly correlated with the pathological regression scale (R=0.579). When the tumor volume reduction rate was 12.5% as an effective threshold for evaluating neoadjuvant chemotherapy, the AUC under the ROC curve was the largest, with sensitivity and specificity of 81.1% and 75.9%, respectively. The median survival time of the effective and ineffective groups was 25 months and 18 months, respectively, and the 2-year survival rate was 73.3% and 51.2%. The total survival time of patients with effective chemotherapy was significantly longer than those with ineffective chemotherapy (P=0.003 6).@*Conclusion@#The volume measurement grading standard can predict the pathological regression of neoadjuvant chemotherapy patients, and it is superior to the Recist score in the evaluation of efficacy and prognosis.
