目的:探讨Mirizzi综合症的诊断治疗特点,以提高其诊断和治疗水平。方法:对35例经手术证实为Mirizzi综合症的临床资料进行回顾性分析。结果:35例Mirizzi综合症患者中仅4例(11.4%)术前确诊。Ⅰ型7例,Ⅱ型17例,Ⅲ型9例,Ⅳ型2例。5例行胆囊切除术,2例行胆囊大部分切除术;胆囊切除、胆囊瓣瘘口修补6例,12例行胆囊切除、胆总管探查、瘘口修补、T管引流术;胆囊切除、胆肠吻合术10例。术后恢复好,随访结果,无严重并发症.结论:Mirizzi综合症术前确诊困难,B超结合MRCP/ERCP检查可以提高Mirizzi综合症的术前确诊率,手术容易损伤胆管,手术方式应据病理损伤程度决定。
目的:总结胸腺类癌的临床表现、病理特征、CT表现及其临床价值。方法:对本院收治的2例胸腺类癌进行分析并结合文献复习。结果:胸腺类癌发病率低,大部分早期患者无临床症状,经胸部X线、CT检查时发现;中晚期始出现症状。病理检查出类癌后,电镜可见神经内分泌颗粒,免疫组化显示神经特异性烯醇化酶、肿瘤嗜铬蛋白A、促皮质素阳性。胸部CT表现特征为起于前上纵隔肿块,常位于心底部大血管和心包周围,肿块内密度不均,可见钙化,增强后轻中度强化,易发生胸内外转移。结论:胸腺类癌是一罕见的前纵隔肿瘤,根据CT特征,结合临床可有助诊断、指导手术、推测预后,因此CT在临床诊治中有非常重要的价值。
Objective To analyze the clinical pathological features of patients with hereditary nonpolyposis colorectal cancer (HNPCC) in northeast Chinese. Methods The clinical data of 101 probands (HNPCC group) from 1982 to 2011 in the Fourth Affiliated Hospital of China Medical University and Tumor hospital of Liaoning Province and 272 patients with sporadic colorectal cancer (sporadic CRC group) in the same period were collected. The clinicopathologic features were compared in two groups. Results In the HNPCC group, the age of onset was younger than 45 years old in 24 patients (23.8%), proximal colon in 31 (30.7%), multiple primary carcinomas in 26 (25.7%), extracolonic carcinoma in 13 (12.9%), mucinous adenocarcinoma in 32 (31.7%), phaseⅠandⅡin 68 (67.3%), high-middle differentiation in 70 (69.3%), and lymph node metastasis in 33 (32.7%), while in the sporadic CRC group were 12 (4.4%), 54 (19.9%), 15 (5.5%), 11 (4.0%), 30 (11.0%), 127 (46.7%), 152 (55.9%), and 140 (51.5%), respectively. There were significant differences between the HNPCC group and the sporadic CRC group (P<0.05). Meanwhile, extracolonic carcinomas in the HNPCC group were endometrial cancer in 3, bladder cancer in 3, breast cancer in 2, brain tumor in 2, ovarian cancer in 1, gastric cancer in 1, and lung cancer in 1. Conclusions Northeast China HNPCC patients with several particular clinicopathologic features such as early onset, frequent localization in proximal colon, proclivity of synchronous and metachronous tumors, excessive mucinous adenocarcinoma, less poorly differentiated tumors, lymph node metastasis, early stage of tumor, and so on. Therefore, clinicopathologic feature is still a preferred method of diagnosis of HNPCC patients or suspected HNPCC patients.
ObjectiveTo investigate the clinicopathologic and epidemiological characteristics of patients with gastric cancer at our hospital in the past six years. Methods A total of 958 patients with gastric cancer were selected from January 2004 to December 2009 and clinicopathologic characteristics such as basic data, pathological type, tumor location, and TNM stage were retrospectively analyzed. ResultsOf the 958 patients,697 cases (72.8%) were male and 261 cases (27.2%) were female, and the age ranged from 26 to 91 years old (mean 62.6 years old). The occurrence rate of gastric cancer was higher in the patients of 46-65 years old (49.4%, 473/958) than that in the patients of ≥66 years old (42.3%, 405/958) and ≤45 years old (8.3%, 80/958). Regarding pathologic type, the majority of advanced gastric cancers (70.1%) were Borrmann Ⅱ, the adenocarcinoma and signetring cell carcinoma accounted for 82.3% and 7.8%, respectively. The cancer of gastric cardia accounted for 53.0%. Stagestratified analysis revealed that the majority of gastric cancers (47.4%) were stage Ⅲ. Conclusion①A prevalence of gastric cancer is found in middle, elderly male patients. Poorly differentiated adenocarcinoma in cardia is prominent. ②Patients with high malignant ganstrie cancer are younger. ③The majority of patients who underwent the surgical treatments have advanced or metastatic tumor, therefore it is necessary to improve the early diagnosis of gastric cancer.
ObjectiveTo summarize the research progress of colorectal mucinous adenocarcinoma.MethodThe articles about colorectal mucinous adenocarcinoma in recent years were reviewed.ResultsThe colorectal mucinous adenocarcinoma was a pathological subtype of colorectal cancer, which had unique clinicopathologic characteristics, relatively low incidence, and poor prognosis. The current studies suggested that the BRAF mutation, microsatellite instability, CpG island methylation, and mucin expression were related to the occurrence and development of colorectal mucinous adenocarcinoma, but its molecular mechanism was still unclear. The colorectal mucinous adenocarcinoma was more common in the proximal colon and female patients. The multiple metastases, extrahepatic and peritoneal metastases were also common. The preoperative MRI examination was very valuable. The main treatment was surgery, and the multidisciplinary discussions were still needed to determine the best treatment for patients in the advanced stage. Compared with other types of colorectal adenocarcinoma, patients with colorectal mucinous adenocarcinoma had a poor prognosis.ConclusionsAlthough we have a certain understanding of colorectal mucinous adenocarcinoma, the study results are limited due to the small sample size of many related articles and the lack of prospective randomized controlled studies. Therefore, more studies are needed in the future to improve the cognition of colorectal mucinous adenocarcinoma. Future research should focus on the molecular mechanism and treatment of colorectal mucinous adenocarcinoma.
