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 a overview of the origins, development of conditional survival and its application to thyroid cancer and prospects the future orientation of research.
ObjectiveTo systematically review vitamin D nutritional status among children and adolescents in China.MethodsCNKI, CBM, WanFang Data, VIP and PubMed databases were electronically searched to collect cross-sectional studies on vitamin D nutritional status among children and adolescents in China from inception to September, 2020. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Meta-analysis was then performed by using Stata 11.0 software.ResultsA total of 23 cross-sectional studies involving 38 047 total sample size were included.The results of meta-analysis showed that the combined vitamin D deficiency rate was 27.9% (95%CI 21.9% to 33.8%), and the inadequate rate was 31.6% (95%CI 25.7% to 37.6%).Subgroup analysis showed that vitamin D deficiency rate of females was higher than that of males (25.3% vs. 22.5%). The vitamin D deficiency rate of children aged 10 to 18 was higher than those aged 6 to 9 (44.9% vs. 32.9%). The vitamin D deficiency rate of children in the north was higher than that in south (36.1% vs. 14.8%). The vitamin D deficiency rate from 2015 to 2018 was higher than that from 2011 to 2014 (34.9% vs. 17.6%). In addition, the vitamin D deficiency rate ofurban children was higher than that of rural children (29.9% vs. 24.9%).ConclusionsThe incidence of vitamin D deficiency among children and adolescents is high in China. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
ObjectiveTo investigate the effect of extranodal extension of axillary lymph nodes metastasis on the prognosis of patients with triple-negative breast cancer (TNBC). MethodsThe TNBC patients with axillary lymph node metastasis admitted to the Nanyang Central Hospital from January 2017 to January 2019 were collected. The clinicopathologic characteristics and prognosis of TNBC patients with or without extranodal extension were analyzed and compared, and the factors affecting prognosis were analyzed. ResultsA total of 216 patients were included, including 123 patients without extranodal extension and 93 patients with extranodal extension. Compared with the patients without extranodal extension, the proportions of the patients with histological grade Ⅲ, 10 or more metastatic lymph nodes, and 5 cm or greater tumor diameter were higher in the patients with extranodal extension (P<0.05). The results of multivariate analysis showed that the 10 or more metastatic lymph nodes was the risk factor affecting the overall survival (OS) and disease-free survival (DFS) of the TNBC patients (P<0.05), and the histological grade Ⅲ and lower human epidermal growth factor receptor-2 (HER-2) expression were the risk factors affecting the OS of the TNBC patients (P<0.05), as well as the extranodal extension was the risk factor affecting the DFS of the TNBC patients (P<0.05). The 5-year cumulative disease-free survival rate of the patients with extranodal extension was worse than that of the patients without extranodal extension (70.2% vs. 83.3%, χ2=6.934, P=0.008). The 5-year cumulative overall survival rate had no statistically significant difference between the them (75.3% vs. 82.1%, χ2=1.969, P=0.161). ConclusionsFrom the results of this study, the prognosis of TNBC patients with extranodal extension is worse. Especially the patients with histological grade Ⅲ, 10 or more metastatic lymph nodes, and with lower HER-2 expression should be paid attention.
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.
