Gastric cancer is the third most common cause of death in men and the fifth common cause of death in women worldwide. Currently, available advanced imaging modalities can predict R0 resection in most patients in the perioperative period. The aim of this study is to determine the role of serum CK18, MMP-9, and TIMP1 levels in predicting R0 resection in patients with gastric cancer. Fifty consecutive patients scheduled for curative surgery with gastric adenocancer diagnosis between 2013 and 2015 were included in the study. One milliliter of blood was taken from the patients included in the study to examine CK18, MMP-9, and TIMP1. CK18, MMP-9, and TIMP1 levels were positively correlated with pathological N and the stage (P < 0.05). The CK18, MMP-9, and TIMP1 averages of those with positive clinical lymph nodes and those in clinical stage 3 were found to be higher than the averages of those with negative clinical lymph nodes and those in clinical stage 2 (P < 0.05). Although serum CK18, MMP-9, and TIMP1 preop measurements in patients scheduled for curative surgery due to gastric adenocarcinoma did not help to gain any idea of tumor resectability, we concluded that our study had valuable results in significantly predicting N3 stage.

Background: Gastric cancer is the 3rd most common cause of death in men and the 5th common in women worldwide. Today, surgery is the only curative therapy. Currently available advanced imaging modalities can predict R0 resection in most patients, but it can only be detected with certainty in the perioperative period. Aim: To determine the role of serum CK18, MMP9, TIMP1 levels in predicting R0 resection in patients with gastric cancer. Methods:Fifty consecutive patients scheduled for curative surgery with gastric adenocarcinoma diagnosed between 2013-2015 were included. One ml of blood was taken from the patients to analyze CK18, MMP9 and TIMP1. Results: CK18, MMP9 and TIMP1 levels were positively correlated with pathological N and the stage (p<0,05). CK-18, MMP-9 and TIMP-1 averages in positive clinical lymph nodes and in clinical stage 3, were found to be higher than the averages of those with negative clinical lymph nodes and in clinical stage 2 (p<0,05). Conclusion: Although serum CK-18, MMP-9 and TIMP-1 preoperatively measured in patients scheduled for curative surgery did not help to evaluate gastric tumor resectability, they were usefull in predicting N3-stage.

Objective: There is an increasing number of studies in the literature reporting that serum platelet/lymphocyte ratio (PLR) can provide useful prognostic data for various cancers. In the present study, the effects of platelet-lymphocyte ratio on survival in stage II/III colorectal cancers (CRC) were examined. Material and Method:A total of 106 Stage II/III CRC patients who underwent curative surgery 2015-2020 were included in the study. Emergency cases and patients diagnosed with other than adenocarcinoma were excluded from the study. The demographic data of the patients, preoperative imaging and laboratory results, postoperative pathology reports, and patient follow-up examination data were obtained from hospital records. The relations between demographic, histopathological, hematological values ​​and the prognosis was analyzed in terms of statistical significance. Results:Among the 106 patients, 62 (58.5%) were male and 44 (41.5%) were female. The mean age was 64.3±12.01 (23-89). The mean follow-up period was calculated as 24.6±15.8 (2-63) months. When the pathology reports were reviewed, it was found that the mean tumor diameter was 5.3±2.33 cm (2-17) and the mean metastatic lymph node was 1.8±2.4 (0-10). The PLR ratio was determined as a poor prognostic factor affecting survival in the cox regression analysis, in which preoperative complete blood count, c-reactive protein and albumin values, neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio (LMR), and PLR were compared, and was separated from other variables (P=0.002 CI= 95%). When variables such as age, clinical stage, and tumor diameter were included in the model, PLR was similarly found to be an important predictive variable (P= 0.002). When only NLR, LMR, and PLR were evaluated, PLR again came to the forefront with a significance value of P=0.01. Also, high neutrophil count, increased platelet distribution volume (PDW), advanced age, and perineural invasion (PNI) were found to be significant factors in predicting poor prognosis. Conclusions: High PLR is a poor prognostic factor for CRC patients. For this reason, it may be necessary to follow a more aggressive strategy in the management of postoperative treatment in patients who have high PLR.

BACKGROUND: Incisional hernias are one of the most common postoperative complications encountered by surgeons in daily practice. In our study, we compared the component separation technique (CST) with and without synthetic mesh in large incisional hernia surgery. MATERIALS AND METHODS: The files of 79 patients who underwent surgery for giant incisional hernia between January 2016 and November 2020 were reviewed retrospectively. The patients were divided into two groups: CST with mesh reinforcement (mesh+ group) and CST without mesh reinforcement (non-mesh group). The groups were compared in terms of recurrence, complications, and other clinical features. RESULTS: There were 36 patients in the mesh+ group and 38 patients in the non-mesh group. There was no significant difference between the two groups in terms of demographic parameters and clinical features. There was a statistically significant difference between the groups in terms of recurrence rate (P = 0.007, OR = 0.17). In addition, there was a significant difference between the two groups in terms of mean operation times (2.8 h and 1.9 h for mesh+ and non-mesh, respectively) (P = 0.000, 95% CI). Regardless of the use of mesh, recurrence was significantly higher in the presence of high body mass index (BMI) (P = 0.003, 95% CI) and comorbidity (P = 0.031, OR = 3.4). CONCLUSION: Repair of giant incisional hernias with mesh-reinforced CST is superior to the non-mesh technique in terms of hernia recurrence. Although CST without mesh reinforcement seems advantageous in terms of complications and operation time, we believe that the mesh-reinforced CST should be applied in suitable patients when the total cost, recurrence, and patient satisfaction are taken into account.
