Objective To investigate the relationship between preoperative hemoglobin, albumin, lymphocyte and platelet (HALP) score, and clinicopathologic features of colon cancer, and to analyze the predictive value of HALP score for postoperative liver metastasis. Methods The clinical data of 163 patients with colon cancer admitted to the 909th Hospital of Joint Logistic Support Force (Dongnan Hospital of Xiamen University) from January 2018 to December 2019 were retrospectively analyzed. According to the occurrence of postoperative liver metastasis, the patients were divided into metastatic group (n=35) and non-metastatic group (n=128). The correlation between preoperative HAPL score and clinicopathologic features of colon cancer was analyzed. The predictive value of HALP score for postoperative liver metastasis of colon cancer was analyzed by using receiver operating characteristic (ROC) curve. The risk factors of liver metastasis after colon cancer surgery were analyzed by using univariate and multivariate logistic analysis. Kaplan-Meier risk curve was drawn, and log-rank test was used to analyze the predictive value of different HALP score for postoperative liver metastasis. Results HALP score were decreased in patients with maximum tumor diameter ≥5 cm, preoperative carcinoembryonic antigen (CEA) ≥5 μg/L, serous membrane and extrasserous infiltration, lymph node metastasis and vascular invasion, and the difference was statistically significant (P<0.05). Multivariate logistic regression analysis showed that HALP score [OR=1.467, 95%CI (1.253, 1.718), P<0.001], maximum tumor diameter [OR=3.476, 95%CI (1.475, 5.358), P=0.013], preoperative CEA level [OR= 6.197, 95%CI (2.436, 6.248), P=0.005], and lymph node metastasis [OR=2.593, 95%CI (1.667, 6.759) , P=0.003] were risk factors for postoperative liver metastasis of colon cancer. ROC curve analysis showed that the area under the curve of HALP score for predicting liver metastasis after colon cancer surgery was 0.908 (0.841, 0.974), the maximum value of the Youden index was 0.738, the optimal cut-off value of the HALP score was 35.5, the sensitivity was 0.852, the specificity was 0.886. Kaplan-Meier risk curve showed that the risk of early postoperative liver metastasis in the low HALP score group was higher than that in the high HALP score group (χ2=8.126, P=0.004). Conclusion Low HALP score in patients with colon cancer is associated with adverse prognosisi related pathological features, and is an influential factor for postoperative liver metastasis of colon cancer, and has predictive value for patients with postoperative liver metastasis of colon cancer.
ObjectiveTo explore the surgical procedures for primary spontaneous pneumothorax without bullae. MethodsWe retrospectively analyzed the clinical data of 52 patients with primary spontaneous pneumothorax without bullae, who underwent surgical treatment in Second Affiliated Hospital of Kunming Medical University between January 2008 and January 2013. There were 46 males and 6 females, with mean average age of 23.2±4.3 years (ranged from 16 to 34 years). According to the different methods of intraoperative surgery, all patients were divided into three groups. The patients in a group Ⅰ (n=20) underwent video-assisted thoracoscope (VATS) selective apex of low energy electric coagulation treatment. The patients in a group Ⅱ (n=21) underwent VATS lung tip part of lung resection. The patients in a group Ⅲ (n=11) received VATS resection of the pleura. The clinical effectiveness among the three groups was compared. ResultsCompared with other two kinds of operation schemes,the leak duration(2.61±1.89 d vs. 4.90±3.20 d vs. 5.36±2.57 d, P=0.012), postoperative chest tube drainage time (3.67±2.13 d vs. 6.00±3.73 d vs. 7.03±2.58 d, P=0.003), postoperative length of hospital stay (4.95±2.16 d vs. 7.35±3.03 d vs. 8.61±2.67 d, P=0.002) and the recurrence rate (0.0% vs. 23.1% vs. 12.5%, P=0.021) of the patients with lung tip part resection of lung tissue by VATS were significantly lower. There were no statistically significant differences in the indicators of the patients with selective apex of low energy electric coagulation by VATS and those with pleural resection by VATS (P>0.05). ConclusionLung tip part of the lung tissue resection by VATS for primary spontaneous pneumothorax without bullae is better than VATS selective apical low energy coagulation treatment and VATS resection of the pleura both in the short and long-term efficacy.
