ObjectiveTo describe the current situation of the prevalence of hepatic hydatidosis, analyze the clinical characteristics and treatment method of the disease, in order to provide scientific basis for personal treatment plans of hepatic hydatidosis. MethodThe clinical data of 121 patients with recurrent hepatic hydatidosis treated between July 2006 and December 2013 were analyzed retrospectively. The general information of hydatid disease of liver, mass of liver, clinical manifestations, laboratory test results, treatment method, effectiveness of the treatment during hospitalization, and follow-up results were collected and analyzed. ResultsMost of the patients were adults from Sichuan and Tibet, and the majority of them had no clear occupation or clear animal contact history and had not taken raw or fresh meat. Lesions in the right lobe occurred in 87 cases, accounting for 71.90%. Abdominal pain and distension were the main clinical manifestations. Twenty-five (20.66%) of these patients were associated with hepatic dysfunction, among whom 23 patients had mild hepatic dysfunction. Alpha-fetoprotein level was increased in one (0.83%) of these cases. A total of 119 of the 121 patients received surgical treatment (98.35%) and all the surgeries were successful. Follow-up results revealed that three of the patients had recurrence. ConclusionsHepatic hydatidosis is an epidemic mainly in the Tibetan district of the West of China. The disease mainly occurs in the right lobe of the liver, which mainly causes mile liver damage. Hepatocellular carcinoma has not been found in these cases. Surgery treatment is the main therapy for liver hydatidosis and may result in good effectiveness.
Objective To analyze risk factors of lymphatic metastasis in early gastric cancer in order to discuss reasonable therapeutic regimen. Methods The clinical data of 148 patients with early gastric cancer surgically treated in the Anhui Tumor Hospital from February 2013 to November 2017 were retrospectively analyzed. The relationship between the lymphatic metastasis with the clinicopathologic characteristics of the patient with the early gastric cancer was analyzed by the univariate and multiple regression analyses. Results The lymphatic metastasis were observed in 15 of 148 patients (10.14%), 1 in the 70 (1.43%) mucosal lesions and 14 in the 78 (17.95%) submucosal lesions. The results of the univariate analysis showed that the patients’ age, size of tumor, macroscopic type, invasion depth, and vascular invasion were related to the lymphatic metastasis in the early gastric cancer (P<0.050), the results of the multiple regression analysis showed that the invasion depth and vascular invasion were the independent risk factors of the lymphatic metastasis in the early gastric cancer (P<0.050). Conclusions Invasion depth and vascular invasion are closely related to lymphatic metastasis in early gastric cancer. Precise evaluation of lymphatic metastasis before treatment is very important to patient with early gastric cancer.
Objective To analyze the clinicopathological characteristics of thymoma patients and the influencing factors for prognosis. Methods Thymoma patients who received treatment in Sichuan Cancer Hospital from March 2015 to March 2021 were collected. Clinical data of the patients were analyzed using Kaplan-Meier and Cox regression analyses. Results A total of 177 patients were included. There were 89 males and 88 females aged 17-88 (52.3±13.0) years, including 160 surgical patients and 17 non-surgical patients. There were 160 patients survived, 17 died of thymoma, and 5 had recurrence and metastasis. Overall, the 1-year, 3-year and 5-year progression-free survival rates were 94.4%, 88.7%, 88.1%, respectively; the 1-year, 3-year and 5-year overall survival rates were 94.9%, 91.5%, 91.0%, respectively. The Kaplan-Meier analysis showed that World Health Organization classification, clinical symptoms, Masaoka-Koga staging, treatment methods and surgery were statistically associated with progression-free survival; clinical symptoms, age, treatment methods and surgery were statistically associated with overall survival (P<0.05). Patients with younger age (P=0.018), without clinical symptoms (P=0.039), and with surgical treatment (P=0.004) had higher overall survival rates; those patients undergoing surgery had a higher progression-free survival rate (P=0.002). Conclusion Age, clinical symptoms and surgical treatment are independent factors influencing the prognosis of patients with thymoma.
ObjectiveTo understand the characteristics of patients who have undergone the removal of the inferior vena cava (IVC) filter so as to provide a reference for optimizing the clinical application strategy of IVC filters. MethodThe demographic and clinical characteristics of patients underwent IVC filter removal in the Department of Vascular Surgery of West China Hospital, Sichuan University from December 2016 to December 2023 were retrospectively collected. ResultsA total of 102 patients were enrolled, including 48(47.1%) males and 54(52.9%) females. The age of the patients was (46.75±16.72) years old, and 75(73.5%) patients were aged between 20 and 59 years old. The proportion of patients who had an IVC filter placed due to concurrent central deep vein thrombosis was the highest, accounting for 48.0% (49/102). Among them, 72(70.6%) patients had the filter removed within 90 d, and 6(5.9%) patients had the filter removed after more than one year. The median duration of filter placement for all patients was 35 d (ranging from 5 to 7 300 d). The filter was removed via interventional method in 91(89.2%) patients, and via open surgery in 10(9.8%) patients. In 1(1.0%) patient failed by endovascular retrieval and followed-up observation. Compared with the interventional treatment, patients who had the filter removed by open surgery had a longer placement time of the filter in the body (median: 32.5 d vs. 136.5 d, P=0.002). ConclusionsFrom the analysis results of this cases data, patients with IVC filters don’t show obvious gender characteristics. The majority of them are young and middle-aged, and interventional method is mostly used for the removal of IVC filters. Patients who use open surgery to remove the filter have a longer placement time in the IVC, suggesting the necessity of early removal of the IVC filter.
