MATERIALS AND METHODS: A total of 140 patients who had compatible ABO blood type with negative T-cell lymphocytotoxicity crossmatch were included in the study and 25% of them were spousal transplant donors. No remarkable differences in acute rejection rate, graft survival, patient survival and serum creatinine level were observed between the spousal and living-related donor groups.
RESULTS: The spousal donor group had a higher degree of HLA mismatch than the living-related donor group. HLA-A mismatch was associated with increased rejection risk at 6 months (odds ratio [OR], 2.75; P = 0.04), 1 year (OR, 2.54; P = 0.03) and 3 years (OR, 3.69; P = 0.001). It was also observed in the deleterious effects of HLA-B and HLA-DQ loci when the number of antigen mismatches increased. The risk was 7 times higher in patients with ≥1 mismatch at HLA-A, HLA-B and HLA-DR loci than those who did not have a mismatch at these loci at 6 months (P = 0.01), 1 year (P = 0.03) and 3 years (P = 0.003).
CONCLUSION: A good match for HLA-A, HLA-B, HLA-DR and HLA-DQ can prevent acute rejection risk in renal transplant patients. Consequently, spousal donor transplants could be a safe intervention in renal patients.
MATERIALS AND METHODS: 18 patients with histologically confirmed early NSCLC (stage I-IIIA) were recruited from October 2019 to January 2021. The serum CEA was measured pre-operatively, and then at 6, 12, 18 and 24 months post-operatively, in conjunction with routine CT and/or CT-PET surveillance scans.
RESULTS: All patients had a curative R0 anatomical resection (lobectomy) with concurrent systematic mediastinal nodal dissection via a uniportal minimally invasive approach under single lung ventilation general anaesthesia. There was no operative, in-hospital or 30-day mortality. 7 patients (39%) had an elevated pre-operative baseline CEA level > 5.0ng/ml. The mean number of nodes sampled intraoperatively was 15. At median follow-up of 42 months, 11/18 (61.1%) patients were recurrence-free. There were no deaths and two recurrences (18.2%) amongst patients with a CEA < 5 (n=11). In the CEA > 5 subgroup (n=7), there were two deaths (28.5%) and 5/7 (71.4%) patients had a radiological recurrence. There was no difference in overall survival however disease-free survival (DFS) was significantly inferior in patients with a baseline CEA > 5. Median DFS was not reached in patients with CEA < 5 and 18 months in those with an elevated CEA > 5 (p<0.001) Conclusion: Almost 40% of local NSCLC patients had an elevated baseline CEA suggesting this is a useful prognostic and surveillance biomarker to incorporate in the routine work-up for any newly diagnosed NSCLC. Despite curative R0 resection and extensive intra-operative mediastinal lymph node sampling, an elevated pre-operative CEA was associated with a significantly reduced DFS and may be a surrogate for more aggressive tumour biology. Such patients will benefit from meticulous post resection surveillance and adjuvant therapy beyond conventional TNM criteria.
METHODS: 240 HER2-positive MBC patients from 2004 to 2015 were retrieved from the surveillance, epidemiology, and end results (SEER) database. All HER2-positive MBC patients were divided randomly into training (n = 144) and validation cohorts (n = 96) according to a ratio of 6:4. Univariate and multivariate Cox regression analyses were used to determine the prognostic factors associated with HER2-positive MBC patients. A clinical prediction model was constructed to predict the overall survival of these patients. The nomogram model was assessed by using receiver operating characteristics (ROC) curves, calibration plots and decision curve analysis (DCA).
RESULTS: The Cox regression analysis showed that T-stage, M-stage, surgery and chemotherapy were independent risk factors for the prognosis of HER2-positive MBC patients. The model could also accurately predict the Overall survival (OS) of the patients. In the training and validation cohorts, the C indexes of the OS nomograms were 0.746 (0.677-0.815) and 0.754 (0.679-0.829), respectively. Calibration curves and DCA verified the reliability and accuracy of the clinical prediction model.
CONCLUSION: In conclusion, the predictive model constructed had good clinical utility and can help the clinician to select appropriate treatment strategies for HER2-positive MBC patients.
METHODS: Gallic acid (1), and methyl gallate (2), were isolated via bioassay-directed isolation, and they exhibited anticancer properties towards several cancer cell lines, examined using MTT cell viability assay. Pyrogallol (3) was examined against the same cancer cell lines to deduce the bioactive functional group of the phenolic compounds.
RESULTS: The results showed that the phenolic compounds could exhibit moderate to weak cytotoxicity towards certain cell lines (GI50 30 - 86 µM), but were inactive towards DU145 prostate cancer cell (GI50 > 100 µM).
CONCLUSION: It was observed that pyrogallol moiety was one of the essential functional structures of the phenolic compounds in exhibiting anticancer activity. Also, the carboxyl group of compound 1 was also important in anticancer activity. Examination of the PC-3 cells treated with compound 1 using fluorescence microscopy showed that PC-3 cells were killed by apoptosis.
