Among colon cancer patients, liver metastasis is a commonly deadly phenomenon, but there are few prognostic models for these patients.<br /><br /> The clinicopathologic data of colon cancer with liver metastasis (CCLM) patients were downloaded from the Surveillance, Epidemiology and End Results (SEER) database. All patients were randomly divided into training and internal validation sets based on the ratio of 73. A prognostic nomogram was established with Cox analysis in the training set, which was validated by two independent validation sets.<br /><br /> A total of 5,700 CCLM patients were included. Age, race, tumor size, tumor site, histological type, grade, AJCC N status, carcinoembryonic antigen (CEA), lung metastasis, bone metastasis, surgery, and chemotherapy were independently associated with the overall survival (OS) of CCLM in the training set, which were used to establish a nomogram. The AUCs of 1-, 2- and 3-year were higher than or equal to 0.700 in the training, internal validation, and external validation sets, inntly associated with poor prognosis of CCLM patients. A nomogram incorporating the above variables could accurately predict the prognosis of CCLM.<br /><br /> The purpose of this study was to evaluate the efficacy and safety of iodine-125 (<br /><br /> I) seeds implantation under ultrasound and computed tomography (CT) guidance in the treatment of residual hepatocellular carcinoma (HCC) located at complex sites after transcatheter arterial chemoembolization (TACE).<br /><br /> This retrospective study analyzed the consecutive medical records of 31 HCC patients with residual tumors located at complex sites (such as large blood vessels, gallbladder, diaphragm dome, etc.) after TACE from May 2014 to December 2018, all of whom received <br /><br /> I seeds implantation therapy. Overall survival (OS), progression-free survival (PFS), recurrence, and complications were documented.<br /><br /> A total of 607 seeds were implanted in 31 patients, with an average of 19.6±10.4 (range, 8-48) seeds per patient. Median OS and PFS were 33 months (95% CI 27.1 months, 38.9 months) and 15 months (95% CI 9.6 months, 20.4 months), respectively. Although univariate analysis showed that albumin, prothrombin time, alpha-fetopr approach and deserves further discussion.<br /><br /> We present a valid and reproducible nomogram that combined the TNM stage as well as the Ki-67 index and carcinoembryonic antigen levels; the nomogram may be an indispensable tool to help predict individualized risks of death and help clinicians manage patients with gastric neuroendocrine carcinoma.<br /><br /> To analyze the long-term outcomes of patients with grade 3 GNEC who underwent curative surgery and investigated whether the combination of carcinoembryonic antigen (CEA) levels and Ki-67 index can predict the prognosis of patients with gastric neuroendocrine carcinoma (GNEC) and constructed a nomogram to predict patient survival.<br /><br /> In the training cohort, data were collected from 405 patients with GNEC after radical surgery at seven Chinese centers. A nomogram was constructed to predict long-term prognosis. Data for the validation cohort were collected from 305 patients.<br /><br /> The 5-year overall survival (OS) was worse in the high CEA group than in the normal CEA group (40.5% vs. 55.2%, p = 0.013). The 5-year OS was significantly worse in the high Ki-67 index group than in the low Ki-67 index group (47.9% vs. 57.2%, p = 0.012). Accordingly, we divided the whole cohort into a KC(-) group (low Ki-67 index and normal CEA) and KC(+) group (high Ki-67 index and/or high CEA). The KC(+) group had a worse prognosis than the KC(-) group (64.6% vs. 46.8%, p &lt; 0.001). KC(+) and the AJCC 8<br /><br /> stage were independent factors for OS. Then, we combined KC status and the AJCC 8<br /><br /> stage to establish a nomogram; the C-index and area under the curve (AUC) were higher for the nomogram than for the AJCC 8<br /><br /> stage (C-index 0.660 vs. [https://www.selleckchem.com/products/ly333531.html read more] 0.635, p = 0.005; AUC 0.700 vs. 0.675, p = 0.020). The calibration curve verified that the nomogram had a good predictive value, with similar findings in the validation groups.<br /><br /> The nomogram based on KC status and the AJCC 8<br /><br /> stage predicted the prognosis of patients with GNEC well.<br /><br />The nomogram based on KC status and the AJCC 8th stage predicted the prognosis of patients with GNEC well.Human stem cell-derived extracellular vesicles (EV) provide many advantages over cell-based therapies for the treatment of functionally compromised tissue beds and organ sites. Here we sought to determine whether human embryonic stem cell (hESC)-derived EV could resolve in part, the adverse late normal tissue complications associated with exposure of the lung to ionizing radiation. The hESC-derived EV were systemically administered to the mice via the retro-orbital sinus to explore the potential therapeutic benefits following exposure to high thoracic doses of radiation (14 Gy). Data demonstrated that hESC-derived EV treatment significantly improved overall survival of the irradiated cohorts (P less then 0.001). Increased survival was also associated with significant reductions in lung fibrosis as quantified by CBCT imaging (P less then 0.01, 2 weeks post-irradiation). Qualitative histological analyses revealed reduced indications of radiation induced pulmonary injury in animals treated with EV. EV were tcontrol cohorts was observed. In conclusion, present findings demonstrate that systemic delivery of hESC-derived EV could ameliorate radiation-induced normal tissue complications in the lung, through a variety of potential mechanisms based on EV cargo analysis.<br /><br /> To analyze the effect of carbon ion (<br /><br /> C<br /><br /> ) radiation may induce bystander effect on A549 cell metastasis and metabonomics.<br /><br /> A549 cell was irradiated with carbon ion to establish the clone survival model and the transwell matrix assay was applied to measure the effect of carbon ion on cell viability, migration, and invasion, respectively. Normal human embryonic lung fibroblasts (WI-38) were irradiated with carbon ions of 0 and 2 Gy and then transferred to A549 cell co-culture medium for 24h. The migration and invasion of A549 cells were detected by the Transwell chamber. The analysis of metabonomic information in transfer medium by liquid phase mass spectrometry (LC-MS), The differential molecules were obtained by principal pomponent analysis (PCA) and the target proteins of significant differences (<br /><br /> = 1.7 × 10<br /><br /> ) obtained by combining with the STICH database. KEGG pathway was used to analyze the enrichment of the target protein pathway.<br /><br /> Compared with 0 Gy, the colony formation, migration, and invasion of A549 cells were significantly inhibited by carbon ion 2 and 4 Gy irradiation, while the inhibitory effect was not significant after 1 Gy irradiation.
