Objective: To investigate the clinical significance of radical pancreatoduodenectomy plus retroperitoneal nerve, lymph node and soft tissue dissection in carcinoma of pancreatic head.
Methods: Forty-six patients with carcinoma of pancreatic head were treated at our hospital from 1995 to 2005. They were divided into two groups: radical pancreatoduodenectomy plus retroperitoneal nerve, lymph node and soft tissue dissection (Group A, n = 25) and routine Whipple's operation (Group B, n = 21). Two groups had no significant difference in age, gender and pre-operative risk factors. And the peri-operative conditions, pathological data and survival rates were compared and analyzed.
Results: There was no difference in tumor size, intra-operative findings, post-operative complications and length of hospitalization. But the number and positive rate of resected lymph node in Group A were significantly higher than those in Group B (P < 0.05). The survival rates of 1, 3-year in Group A were 80% and 52.9% respectively. And they were higher than those in Group B (P < 0.05). There was significant difference in the survival rates between patients with nerve infiltration and those without in Group A (P < 0.05).
Conclusion: The radical pancreatoduodenectomy plus retroperitoneal nerve, lymph node and soft tissue dissection can effectively remove the lymph node and nerve tissues with tumor infiltration and reduce the local recurrent rate so as to improve the long-term survival rate.

Objectives: We aimed to compare the outcomes of patients with T1-T2N0M0 glottic squamous cell carcinoma who underwent either partial laryngectomy (PL) or radiotherapy (RT).
Methods: A retrospective analysis of 562 patients treated with RT (n = 151) or PL (n = 411) was conducted. The Kaplan-Meier method was used to estimate outcomes.

Aleutian mink disease (mink plasmacytosis) is a severe immune complex-mediated condition caused by the Aleutian Mink Disease Virus (AMDV), the most significant pathogen affecting mink health in the industry. Several studies have shown that AMDV epidemics can result in millions to tens of millions of dollars in economic losses worldwide each year. In this study, we developed a TaqMan probe-based real-time PCR technology (TaqMan-qPCR) for the specific, sensitive, and reproducible detection and quantification of AMDV in mink tissues by the VP2 gene, achieving detection limits as low as 1.

The role of p53 expression in colorectal cancer (CRC) was investigated in this immunohistochemical analysis of 110 CRC patients. The study aimed to explore the relationship between p53 expression and clinicopathological features, such as tumor grade, size, lymph node involvement, and molecular subtypes. The mean age of patients was 52.

Objective: To review a rare case of a lateral neck mass pathologically confirmed as an encapsulated papillary thyroid carcinoma in our center for complementing the lack of management of rare cases, and to explore the differentiation of primary ectopic thyroid carcinoma and metastatic disease in the context of the presence of malignant tumors within the situ thyroid gland.
Methods: We searched for studies on lateral neck ectopic thyroid cancer to compare and analyze it with metastatic carcinoma of the thyroid gland in terms of clinical features, imaging manifestations, pathological features at molecular level, and treatment principles.
Results: Based on available data, we concluded that the mass of this patient was consistent with metastatic lateral neck ectopic thyroid carcinoma.
Meta-analysis of the clinicopathologic features of endometrial cancer molecular staging.

Objective: The 2013 TCGA identified four molecular subgroups of endometrial cancer; however, the data results for most of the pathological features were varied and of low value for clinical application. Therefore, a meta-analysis of articles related to the clinicopathological features of molecular typing was performed to observe how the prevalence of the four subgroups varied across different pathological features and whether they were associated with certain specific pathological features and to understand how molecular typing may influence current pathological assessments.
Methods: PubMed, Embase, Web of Science, CNKI, Wanfang, and VIP were searched from the time of library construction until May 2024, and the following data were extracted: histological type, FIGO grade, FIGO stage, LVSI, depth of muscularis propria infiltration, and lymph node status of each TCGA group.
