Objective To study the data of combined hepatocellular cholangiocarcinoma (CHCC) and to explore its clinical characteristics and prognostic factors. Methods Clinical data of 41 patients with radical resection of CHCC were retrospectively analyzed, and the prognostic factors were analyzed by univariate and multivariate analysis. Results In 36.6% cases of 41 patients with CHCC, the elevated levels of both AFP and CA19-9 were detected. And 78.0% cases got the elevated levels of CK7 and (or) CK19 and Glypcian-3 and (or) hepatocyte. Multiple analysis revealed lymph node involvement was independent prognostic factor for overall survival. Conclusions CHCC is a special type of primary liver cancer and shows some intermediated characteristics between hepatocellular carcinoma and cholangiocarcinoma. The long-term survival of the patients should be affected by the residual of metastasis lymph nodes, and the surgical treatment should be individualized at the present stage.
Thyroid cancer is the most common malignancy of the head and neck region and the endocrine system, with its incidence increasing rapidly worldwide. While the overall prognosis of thyroid cancer is favorable, patients with high-risk features (e.g., extensive extrathyroidal extension or distant metastasis) or specific histologic types (e.g., anaplastic cancer) exhibit significantly poorer outcomes. Traditional survival analysis only provides static estimates of survival rates (e.g., 5- or 10-year survival) from the time of diagnosis or surgery. However, mortality risk dynamically changes over time, rendering such static measures inadequate for assessing evolving prognosis—particularly for patients who have already survived for a certain period after treatment. Conditional survival serves as a dynamic prognostic tool, quantifying the probability that a patient who has already survived x years will survive an additional y years. Understanding and utilizing conditional survival is critical for both clinicians and patients that it informs therapeutic decision-making and follow-up strategies for clinicians, while empowering patients to make informed life plans based on evolving survival expectations. Hence, we present an overview of the origins, development of conditional survival and its application to thyroid cancer and prospects the future orientation of research.
ObjectiveTo explore risk factors for pancreatic fistula and severe pancreatic fistula (grade B and C) after distal pancreatectomy. MethodsOne hundred and fifty patients underwent distal pancreatectomy were collected and analyzed from January 2012 to December 2014 in this retrospective study,among which 61 cases were male,89 cases were female,age from 18 to 78 years old.The risk factors for pancreatic fistula and severe pancreatic fistula after distal pancreatectomy were analyzed by univariate and multivariate logistic regression analysis. ResultsIn these patients,136 cases were underwent laparotomy,8 cases were underwent total laparoscopic surgery,6 cases were underwent hand assisted laparoscopic surgery;39 cases were preserved spleen,111 cases were combined splenectomy.Technique for closure of the pancreas remnant,15 cases were used cut stapler (Echelon 60,EC60),77 cases were used cut stapler (Echelon 60,EC60) combined with manual suture,52 cases were underwent manual cut and suture,and 6 cases were underwent pancreatic stump jejunum anastomosis.The total incidence of complications was 36.0%(54/150),the postoperative hospitalization time was (9.1±6.2) d,the reoperation rate was 2.7%(4/150),the perioperative mortality was 0,the incidence of postoperative pancreatic fistula was 34.7%(grade B and C was 10.0%).In these patients with postoperative pancreatic fistula,the postoperative hospitalization time was (12.6±9.3) d,the reoperation rate was 7.7%(4/52).The results of the univariate and multivariate logistic regression analysis showed that the hypoproteinemia (OR=4.919,P<0.05) was the risk factor for pancreatic fistula after distal pancreatectomy,the malignancy (OR=4.125,P<0.05) was the risk factor for severe pancreatic fistula after distal pancreatectomy. ConclusionsIncidence of pancreatic fistula after distal pancreatectomy is related to hypoproteinemia before operation,it is needed to improve the nutritional status by nutrition treatment for reducing postoperative pancreatic fistula.If patient with malignancy has postoperative pancreatic fistula,it is likely to be severe pancreatic fistula.
Objective To investigate the expressions of aldehyde dehydrogenase 1 (ALDH1) and sex determining region Y-box protein 2 (SOX2) in breast cancer tissues and their clinical significance. Methods Immunohistochemistry was used to detect the expressions of ALDH1 and SOX2 protein in cancerous and its paracancer tissues of 80 patients with breast cancer treated in our hospital from 2017 to 2019, and to analyze the correlation between the expressions of ALDH1 and SOX2 protein, as well as the relationship between their expression and clinicopathological characteristics and prognosis of breast cancer patients. Results The positive expression rates of ALDH1 and SOX2 protein in breast cancer tissues were 75.0% and 62.5%, respectively. The positive expression rates of ALDH1 and SOX2 protein in paracancer tissues were 30.0% and 21.3%, respectively. The positive rates of ALDH1 and SOX2 protein expressions in breast cancer tissues were higher than those in paracancer tissues, and the difference was statistically significant (P<0.05). The expressions of ALDH1 and SOX2 proteins in breast cancer tissues were correlated with histological grade, TNM stage and axillary lymph node status of breast cancer (P<0.05). By Spearman correlation analysis, ALDH1 was positively correlated with SOX2 expression (rs=0.507, P<0.001). The univariate analysis of statistically significant indicators and the combination of clinical characteristics of the logistic regression multivariate analysis found that, breast cancer tumor size, histological grade, TNM stage, axillary lymph node status and ALDH1 protein and SOX2 protein expressions were not significantly correlated with those reaching disease-free survival (DFS) after follow-up (P>0.05, which may be affected by small sample size and small number of endpoint events). The Kaplan-Meier method was used to plot survival curves, and log-rank test results showed that the cumulative DFS rates of patients with positive ALDH1 and SOX2 protein expression were lower than those of with negative expression (P<0.05). Conclusions ALDH1 and SOX2 proteins are highly expressed in breast cancer tissues, and they are positively correlated. Survival curves show that positive ALDH1 and SOX2 proteins in breast cancer tissues tend to have a poorer prognosis.
ObjectiveTo summarize the clinical characteristics and treatment of acute cellulitis of shank after total knee arthroplasty. MethodsWe retrospectively analyzed the clinical data of five patients with delayed acute cellulitis of shank after total knee arthroplasty treated in our hospital between January 2008 and January 2013. The clinical characteristics, treatment and prognosis of the disease were then summarized and analyzed. ResultsThe delayed acute cellulitis of shank after total knee arthroplasty was mainly caused by tinea pedis, which resulted in skin damage and bacteria diffusion. The main clinical manifestations were pain and swelling around the knee joint and shank. The laboratory test found the increasing of C-reactive protein, erythrocyte sedimentation rate, white blood cell and neutrophils. Two cases were caused by hemolytic streptococcus according to blood culture. All patients were discharged after treatment without periprosthetic infection. ConclusionAccording to the typical clinical manifestations and laboratory test, the diagnosis of delayed acute cellulitis of shank is not difficult. Timely and comprehensive treatment should be emphasized to seek and eradicate the primary lesions, such as tinea pedis, subcutaneous ulcer and carbuncle.
