ObjectiveTo understand variations in clinical epidemiology of lung cancer and to help with early accurate diagnosis and treatment of lung cancer.MethodsThis research was based on the Lung Cancer Database of West China Hospital of Sichuan University. Clinicopathological data of inpatients with primary lung cancer from 2011 to 2018 was collected for analysis. Information regarding sex, age, smoking history, surgical resection modalities, TNM stage of tumor, and pathological subtypes was included.ResultsA total of 23 228 inpatients with primary lung cancer were included in this research. There were 1 932, 2 029, 2 162, 2 773, 2 975, 3 318, 3 993, and 4 046 patients in every single year from 2011 to 2018, respectively. The male-to-female ratio of patients had changed significantly from 2.00∶1 in 2011 to 1.34∶1 in 2018 (P<0.001). Statistically significant difference was found in age distribution of patients in different years, while elderly always accounted for the majority of all patients. More nonsmokers were among the group of lung cancer patients, the proportion of whom rose from 41.61% in 2011 to 52.47% in 2018 (P<0.001). The proportion of adenocarcinoma in all subtypes rose from 54.04% in 2011 to 71.73% in 2018, while the proportion of squamous carcinoma dropped from 29.04% to 17.67% simultaneously. From 2011 to 2018, the proportion of stage Ⅰ lung cancer rose from 15.68% to 40.79%. Patients with stage ⅠA1 accounted for 11.82% in 2018. In 2018, 60.78% of stage ⅠA patients had gone through surgical resection modalities, forming a stark contrast with the fact that only 26.48% of stage ⅠA patients adopted surgeries in 2011.ConclusionsFrom 2011 to 2018, the total number of lung cancer patients increased year by year. The proportions of female patients and nonsmokers rose significantly. Adenocarcinoma accounted for the highest proportion of all subtypes, followed by squamous cell carcinoma. There were more patients with early lung cancer and less with advanced lung cancer diagnosed, implying a gradual accumulation of weight on the early stages according to the TNM classification of lung cancer.
ObjectiveTo summarize the pathological characteristics of primary left ventricular tumors and their influence on surgical treatment.MethodsThe clinical data of 32 patients with primary left ventricular tumor in Fuwai Hospital from January 2008 to March 2019 were retrospectively analyzed, including 17 males and 15 females with an average age of 33.88±17.89 years. The impact of different types of left ventricular tumor pathology on the surgical outcome was analyzed.ResultsThirty-two patients with primary left ventricular tumors underwent surgery. Postoperative pathological biopsy results revealed benign tumor in 31 patients, including myxoma in 10 patients, lipomas in 7 patients, fibroma in 4 patients, hemangioma in 3 patients, rhabdomyoma in 2 patients, cyst in 2 patients, schwannoma in 1 patient, papillary fibroelastoma in 1 patient, cavernous hyperplasia of valvular lymphatic vessels in 1 patient. There was 1 patient of carcinoid (low-grade malignant tumor). Thirty patients underwent tumor resection surgery under hypothermic anesthesia and cardiopulmonary bypass followed by cardiac arrest while 2 patients without cardiopulmonary bypass. Nine patients received partial resection of the tumor, including lipomas in 6 patients, rhabdomyoma in 2 patients, schwannoma in 1 patient. Twenty-three patients received complete resection of the tumor. There were no in-hospital deaths, bleeding, secondary thoracotomy, low cardiac output, renal failure, postoperative embolism or other surgical complications. All the patients were normal before they were discharged out of the hospital. Their average postoperative hospital stay was 8.1±2.7 d. Within 6 months after the surgery, all 32 patients returned to the hospital for reexamination, and ultrasound results were all normal. Afterwards, the patients were followed up by telephone or in an outpatient clinic, and 3 patients were lost. The follow-up rate was 90.63%. During the follow-up of 3-120 (61.4±38.5) months, among the 9 patients whose tumors were partially resection, 2 patients recurred. One patient with schwannoma recurred 30 months after the surgery, and in the other patient lipomas grew 15 months later which resulted in massive regurgitation of the mitral valve.ConclusionSurgical resection is the first choice for the treatment of left ventricular benign tumors. For malignant left ventricular tumors, it is necessary to be cautious, and the surgical risk needs to be carefully evaluated. Most of the primary left ventricular tumors need to be operated as soon as possible. A surgeon should develop different surgical strategies according to different pathological types of tumors.
目的 分析原发性乳腺淋巴瘤（PBL）的临床病理特点、诊断、治疗及预后。 方法 回顾分析2000年12月－2011年10月收治的19例PBL患者的临床资料和治疗随访情况。 结果 19例PBL患者均为女性，年龄34～72岁。根据Ann Arbor临床分期，Ⅰ期患者9例，Ⅱ期7例，Ⅲ期3例，而病理类型以弥漫大B淋巴瘤为主（13/19）。全部患者随访时间为6～113个月，中位随访时间为45个月，5年生存率为36.8%。 结论 PBL其预后与病理类型、分期及治疗方式有关。手术联合放射化学疗法为主要治疗方式，腋窝淋巴结清扫有一定的意义，但对PBL预后的影响值得商榷。此外，PBL易出现中枢神经系统转移，应定期复查。
ObjectiveTo summarize the incidence, patterns and laws of perineural invasion, and explore the path and the influencing factors of perineural invasion in hilar cholangiocarcinoma. MethodsA clinicopathologic study was conducted on sections from 52 patients with hilar cholangiocarcinoma to summarize the incidence and patterns of perineural invasion. The relationship of perineural invasion to lymph node metastasis, serum CA19-9, CEA, total bilirubin (TBIL) level, Bismuth-Corllet classification, or tumor penetration depth of bile duct walls was analyzed by association analysis. ResultsThe overall incidence of perineural invasion was 90.38% (47/52). However, the incidences of perineural invasion had no significant differences among various differentiated adenocarcinoma groups (P > 0.05). The incidences of perineural invasion were not correlated with the lymph node metastasis, serum CA19-9, CEA, TBIL level, and Bismuth-Corlette classification (P > 0.05), which was correlated with the tumor penetration depth of bile duct walls (P < 0.01). There were four patterns of perineural invasion, sequenced them according their incidences from high to low as follows: typeⅡ> typeⅢ> typeⅣ> typeⅠ. The pattern of perineural invasion was correlated with the degree of tumor differentiation (χ2=31.04, P < 0.01). ConclusionsThe incidence of perineural invasion is very high in hilar cholangiocarcinoma. The patterns of perineural invasion are similar in the same patient, and a variety of invasion patterns might coexist. While the pattern of perineural invasion is correlated with the degree of tumor differentiation. The incidence of perineural invasion is correlated with the tumor penetration depth of bile duct walls.
ObjectiveBy applying the mutual corroboration in the diagnosis, we aimed to improve the accuracy of preoperative imaging diagnosis, select the appropriate timing of operation and guide the follow-up time for patients with pulmonary nodules.MethodsClinical data of 1 368 patients with pulmonary nodules undergoing surgical treatment in our department from July 2016 to October 2019 were summarized. There were 531 males and 837 females at age of 44 (21-67) years. The intraoperative findings, images and pathology were classified and analyzed. The imaging pathology and pathological changes of pulmonary nodules were shown as a dynamic process through mutual collaboration and interaction.ResultsOf 1 368 patients with pulmonary nodules, 376 (27.5%) were pure ground-glass nodules, 729 (53.3%) were mixed ground-glass nodules and 263 (19.2%) were solid nodules. Among the pure ground-glass nodules, adenocarcinoma in situ (AIS) accounted for the highest proportion (156 patients), followed by microinvasive adenocarcinoma (MIA, 90 patients), atypical adenomatous hyperplasia (AAH, 85 patients), and benign tumors (20 patients). Among mixed ground-glass nodules, 495 patients were invasive adenocarcinoma (IA) and 207 patients of MIA. In solid nodules, patients were characterized by pathology of either IA (213 patients) or benign tumors (50 patients), and no patient was featured by AAH, AIS or MIA.ConclusionThe mutual collaboration and interaction can improve the accuracy of preoperative diagnosis of pulmonary nodules, and it supports the choice of operation timing and the judgment of follow-up time.
ObjectiveTo analyze the relative factors of lymph-nodes metastasis (LM) in patients with cervical cancer. MethodsThe clinico-pathological data of 136 patients with stageⅠ A-Ⅱ A of cervical cancer who underwent surgical therapy from January 2005 to December 2010 were retrospectively analyzed. The correlation between clinico-pathological parameters and LM was analyzed by univariable χ2 analysis and multivariable logistic analysis. ResultsThe total LM rate (LMR) was 14.0% (19/136). The rate of LM in obturator was the highest (63.2%), and then the rate between the external and internal iliac was 42.1%. The rate of deep inguinal lymph nodes and para-aortic lymph node was 0.0%. There was correlation between the clinic staging, depth of stromal invasion, histologic subtype, parametrial invasion, vaginal invasion and LM in univariable analysis (P<0.05). While in multivariable analysis, the correlation with LM was only existed between the clinic staging, histologic subtype, depth of stromal invasion and LM. ConclusionClinic staging, histologic subtype, depth of stromal invasion are high risk factors of LM.
Four hundred and eighty two paients suffering from intrahepatic bile duct stone undergoing lobectomy and segmental resection (from 1975 to 1994,9) has reported. 63% of the patient in this group underwent 1-5 operations, including different types of biliary-intestinal anastomosis (21.6%). 482 cases underwent different types of hepatectomy, including left lateral-lobetomy 321 cases (66.6%),left hemihepatectomy 80 cases(16.6%), right hemihepatectomy 19 cases (3.9%), and multiple segmental resections 39 cases (8.1%, including Ⅴ+Ⅷ 11 cases, Ⅵ+Ⅶ 28 cases). Other type hepatectomy combined with guadrate lobectomy 20 cases (4.1%). Postoperative complication rate was 10.2%, including diliary fistula. hemobilia and subdiaphragmatic and resectional surface infectioin, 85% of the patients were followed up with an excellent result of 88%. The authors emphsize that hepatic lobectomy nad segmental resection is the core of treatment and selection of operative methods depends on clinical-patholigic types of the disease.
