ABSTRACT

Objective:To explore the prognostic value of combined fibrinogen/albumin ratio (FAR) and CA724 in patients with stage Ⅱ/Ⅲ gastric cancer after radical resection.Methods:A total of 932 patients were enrolled in the study, and the best cut-off values of CEA, FAR, NLR and other variables were obtained through ROC curve analysis. According to the FAR-CA724 score, patients were divided into 3 groups: FAR-CA724=0 (CA724<3.43 ng/ml and FAR<0.083), FAR-CA724=1 (CA724≥3.43 ng/ml and FAR≥0.083) and FAR-CA724=2 (CEA≥3.43 ng/ml and FAR≥0.083).Results:After FAR-CA724 grouping, the patient's age (χ 2=12.02, P=0.002), gender (χ 2=15.91, P<0.001), tumor size (χ 2=18.22, P<0.001), hypertension (χ 2=6.35, P=0.042), tumor location (χ 2=26.09, P<0.001), degree of differentiation (χ 2=12.46, P=0.002) and pTNM staging (χ 2=6.68, P=0.035) are significantly different. Survival analysis showed that there were significant differences in OS between the three groups of patients (FAR-CA724=0, 1, and 2: 88.2%, 64.3% and 37.8%, respectively, P<0.001). By multivariate analysis FAR-CA724 is an independent risk factor affecting OS in patients with stage Ⅱ/Ⅲ gastric cancer after radical surgery. Conclusions:Preoperative FAR-CA724 may be a potential blood marker for predicting the prognosis of GC patients.

ABSTRACT

Objective:To investigate the expression of annexin A9(ANXA9)in gastric cancer tissues and cells and its effect on the proliferation of gastric cancer cells and the ability of subcutaneous tumorigenesis in nude mice.Methods:Immunohistochemistry and qPCR were used to detect the relationship between the expression of ANXA9 and clinicopathological parameters and prognosis in gastric cancer and paired adjacent tissues.Lentivirus transfection was used to inhibit the expression of ANXA9 in gastric cancer cell line SGC-7901. Cell counting kit-8 (CCK-8) and clone formation were used to detect the changes of proliferation of SGC7901, flow cytometry to detect the changes of SGC-7901 cell cycle, and nude mouse model bearing subcutaneous gastric cancer xenograft was established using SGC-7901 cells with stable ANXA9 knockdown to assess the effect of low expression of ANXA9 on xenograft growth.Results:Immunohistochemistry showed that the expression level of ANXA 9 was 67.1% and 30.7% in gastric cancer tissues and adjacent tissues, respectively. qPCR showed that the expression levels of ANXA 9 mRNA in gastric cancer tissues and adjacent tissues were 0.142±0.107 and 0.819±0.191, respectively. The difference was statistically significant ( P<0.05). The high expression of ANXA9 was different from the low expression group in the degree of tissue differentiation ( P<0.05), and the median survival time was 50 and 59 months, respectively. OD values of the transfected cells were 0.285±0.025, 0.386±0.031, 0.711±0.032, 1.007±0.084, 1.552±0.055 and 0.274±0.026, 0.380±0.049, 0.714±0.035, 1.106±0.081, 1.561±0.060, respectively, compared with 0.294±0.011, 0.445±0.046, 1.076±0.096, 1.588±0.095, 2.286±0.110 in NC group ( P<0.05). Cell clone formation in the transfection group was 207±12 and 225±14, lower than that in the NC group (412±14, P<0.05). After inhibiting the expression of ANXA9, the proportion of G 0/G 1 phase cells in the transfection group was 62.80% and 55.87%, respectively, significantly increased compared with 44.37% in the NC group. The proportions of S-phase cells in the transfected group were 22.74% and 21.44%, respectively, which were significantly lower than that in the NC group 29.19% ( P<0.05), after stable interference with ANXA9, the growth rate of transplanted tumors was significantly slower than that of the control group. On the 23rd day, the average volume of transplanted tumors in the two groups were (625±49) mm 3 and (303±157) mm 3, respectively, and the mass of tumor tissues in the two groups were (1.60±0.11) and (0.57±0.09) g ( P<0.05). Conclusions:Down-regulation of ANXA9 expression can inhibit the proliferation of gastric cancer cells and the ability of subcutaneous tumor formation in nude mice.

ABSTRACT

Objective To investigate the effect of the first surgical treatment on progression-free survival (PFS)time of retroperitoneal liposarcoma and the prognosis.Methods We analyzed the clinical data of 74 cases of retroperitoneal liposarcoma from 1998 to 2016 in He'nan Cancer Hospital (Zhengzhou University Affiliated Tumor Hospital Department of General Surgery).Results The results demonstrated that progression-free survival time of the first surgical resection of retroperitoneal liposarcoma in patients related with tumor necrosis (P < 0.001),lobulated tumor (P < 0.001),symptoms (P =0.013),Ro resection (P =0.003),distant metastasis (P =0.028),postoperative chemotherapy (P =0.006) and tumor differentiation (P < 0.001).Progression-free survival time was not correlated with gender,age of first diagnosis,the invasion of adjacent organs,tumor size,operation time and combined organ resection (all P>0.05).The rate of 1-year,3-year,5-year survival time attached to PFS≤24 m and PFS >24 m were 93.7% vs.94.7,90.5% vs.80.9%,58.4% vs.74.8%(P=0.111).Conclusion The first attempt of radical resection determines progression-free survival of retroperitoneal liposarcoma,however,patients' PFS was not related with their overall survival.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the application of three-stitch preventive transverse colostomy in anterior resection of low rectal cancer.</p><p><b>METHOD</b>From May 2015 to March 2016, 70 consecutive low rectal cancer patients undergoing anterior resection and preventive transverse colostomy in our department were recruited in this prospective study. According to the random number table method, 70 patients were divided into three-stitch transverse colostomy group(observation group, n=35) and traditional transverse colostomy group(control group, n=35). Procedure of three-stitch preventive transverse colostomy was as follows: firstly, at the upper 1/3 incision 0.5-1.0 cm distance from the skin, 7# silk was used to suture from outside to inside, then the needle belt line went through the transverse edge of the mesangial avascular zone. At the lower 1/3 incision 0.5-1.0 cm distance from the skin, 7# silk was used to suture from inside to outside, then silk went through the transverse edge of the mesangial avascular zone again and was ligatured. Finally, in the upper and lower ends of the stoma, 7# silk was used to suture and fix transverse seromuscular layer and the skin. The operation time and morbidity of postoperative complications associated with colostomy were compared between two groups.</p><p><b>RESULTS</b>There were no significant differences in baseline data between the two groups(all P>0.05). The operative time of observation group was shorter than that of control group [(3.2±1.3) min vs. (15.5±3.4) min, P<0.05]. Incidences of colostomy skin-mucous separation, dermatitis, stoma rebound were significantly lower in observation group [5.7%(2/35) vs. 34.3%(12/35), P=0.007; 8.6%(3/35) vs. 31.4%(11/35), P=0.036; 0 vs. 17.1%(6/35), P=0.025, respectively], while incidences of parastomal hernia and stoma prolapse in two groups were similar (both P>0.05).</p><p><b>CONCLUSION</b>Compared with traditional transverse colostomy method, the three-stitch preventive transverse colostomy has more operating advantages and can reduce postoperative complications associated with colostomy.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the technical advantages of nano carbon development combined with artery approach in lymph node sorting of rectal cancer.</p><p><b>METHODS</b>From December 2015 to June 2016, 70 patients with of rectal cancer in General Surgery Department of Henan Cancer Hospital were randomly divided into nano carbon development combined with artery approach group(artery approach group) and conventional group. Specimen of artery approach group was placed on the sorting table. Anatomy was performed from the root of inferior mesenteric artery to left colonic artery, sigmoid artery and superior rectal artery. Along the arterial vessel shape, the black-stained lymph nodes and non-stained lymph nodes (perhaps pink, pale yellow, white or pale brown) were examined carefully using visual and haptic combination method for identification of lymph node. From the root of inferior mesenteric artery, central lymph nodes were sorted. Along the vessel shape, vascular lymph nodes were sorted. Intestinal lymph nodes around the rectum were examined as well. Then, specimen was reversed on the sorting table and underwent sorting as above after the examination of obverse. The conventional group received routine method. The total number, the average harvested number, the number of positive lymph nodes and the number of patients with lymph nodes less than 12 were compared between two groups.</p><p><b>RESULTS</b>Among 70 cases, 37 were male and 33 were female with the median age of 57(32-88) years old. Dixon resection was performed in 46 cases, and Miles resection in 24 cases. Total sorting lymph node was 1 105, including 641 of artery approach group and 464 of control group with significant difference (t=20.717, P=0.000). Lymph node sorting time of artery approach group was (12.6±3.9) minutes, which was shorter than (18.2±4.1) minutes of control group (t=12.464, P=0.000). In artery approach group, number of lymph node with diameter less than 5 mm was 142, sorting rate was 22.2%(142/641), of which 29 were positive(20.4%). In conventional group, 37 lymph nodes with diameter less than 5 mm were found, and sorting rate was 8.0%(37/464), of which 6 were positive(16.2%). Number of the first station of lymph node sorting in artery approach group and conventional group was 282(44%) and 169(36.4%); number of the second station lymph node sorting was 230(35.9%) and 180(38.8%); number of the third station lymph node sorting was 129(20.1%) and 115(24.8%).</p><p><b>CONCLUSION</b>The method of nano carbon development combined with artery approach in lymph node sorting of rectal cancer has some advantages, such as simple operation, more harvested lymph nodes, and more accurate pathological staging.</p>

ABSTRACT

Objective:To retrospectively analyze related factors of subtype transformation and to identify prognostic factors for pa-tients with retroperitoneal liposarcoma (RPLS). Methods:This study retrospectively analyzed the clinical data of 92 patients with RPLS, which were confirmed by postoperative pathology from July 1997 to October 2014 in Henan Provincial Tumor Hospital. Related studies were reviewed, and the prognoses were followed up. The factors may affect subtype transformation or prognoses were applied to the statistical analysis. Results:A total of 74 patients with RPLS were included according to the recruiting standard. The 5-year survival rate was 48.65%. Lobulated tumors (P=0.013) were the correlative factors that influenced subtype transformation. The Log-rank test showed that the age at diagnosis (P=0.045), multi-visceral resection (P=0.042), tumor necrosis (P<0.001), subtype transformation (P<0.001), and malignant level of pathological subtypes of the first operation (P<0.001) influenced overall survival. Multivariate Cox re-gression analysis showed that tumor necrosis and the malignant level of the initial histological grade were independent factors of over-all survival. Conclusion:Lobulated tumors are likely to transform the subtype. The prognosis of patients with RPLS is correlated with multi-visceral resection, tumors necrosis, subtype transformation, and the malignant level of pathological subtypes of the first opera-tion. Multi-visceral resection could not improve the 5-year survival rate of RPLS, and adjuvant therapy could not improve the prognosis.
