ObjectiveTo investigate the relationship between preoperative C-reactive protein (CRP)/albumin ratio (CAR) and National Institutes of Health (NIH) risk classification in patients with gastric stromal tumors.MethodsClinical data of 108 patients with gastric stromal tumors admitted to the First Affiliated Hospital of Kunming Medical University from February 2010 to November 2016 were retrospectively collected. With the median of CAR as the critical value, patients were divided into high CAR group (CAR>0.048) and low CAR group (CAR≤0.048). Then observed the general clinicopathological characteristics and survival status of patients with higher and lower CAR value.ResultsThere were significant differences in NIH classification, tumor diameter, and mitosis between the high CAR group and low CAR group (P<0.05). Compared with the low CAR group, the tumors in the high CAR group had larger diameter, higher mitotic figure, and higher NIH grade. Survival analysis showed that the prognosis of the low CAR group was better than that of the high CAR group (χ2=15.152, P<0.001).ConclusionsCAR is closely related to the malignant index and NIH risk classification of gastric stromal tumors. It can be used as an index for evaluating the malignant degree of gastric stromal tumors, and it is expected to be an important reference factor for clinical NIH risk classification and prognosis.
ObjectiveTo investigate the feasibility and safety of laparoscopic resection in treatment of gastric stromal tumors at difficult sites.MethodsA retrospective analysis of 64 cases of gastric stromal tumors at the difficult sites in Renmin Hospital of Wuhan University from January 2013 to October 2018 was performed. According to the patient’s surgical procedure, 64 cases were divided into two groups, there were 26 cases in the laparoscopic group and 38 cases in the open group. The clinical pathology data, surgical indexes, and follow-up results of the two groups were compared.ResultsAll the operations were successfully completed, and the patients in the laparoscopic group did not conversate to open surgery. There were no complications such as postoperative hemorrhage, anastomotic leakage, cardia or pyloric stenosis, abdominal infection, and no positive margin and tumor rupture. The postoperative venting time, visual analogue scale of pain on 1 day after operation, and hospital stay in the laparoscopic group were better than those of the open group (P<0.05). There were no local recurrence cases in the two groups. In the open group, two cases of middle-high risk patients did not take imatinib according to the doctor’s advice and suffered from liver metastasis. In the laparoscopic group, one case of high-risk patient did not take medicine regularly and suffered from liver metastasis too. There was no significant difference in survival situation between the two groups (P>0.05).ConclusionLaparoscopic resection is safe and feasible for gastric stromal tumors with a diameter of less than 5 cm, it has shorter recover time and shorter hospital stay than open surgery, which can be clinically promoted.
