The study cohort was divided into internal training and testing datasets in a 70:30 ratio for further analysis. A total of twenty-four variables were included to develop predictive models for r NACT by multiple MLbased algorithms. A feature selection approach was used to identify optimal predictive factors. These models were evaluated by the receiver operating characteristic(ROC) curve for predictive performance.RESULTS Analysis identified several significant differences between the r NACT and nonr NACT groups, including total cholesterol, low-density lipoprotein, neutrophilto-lymphocyte ratio, body mass index, platelet count, albumin-to-globulin ratio, platelet-to-lymphocyte ratio, and lymphocyte-to-monocyte ratio. The areas under the curve of the six models ranged from 0.81 to 0.96. Some ML-based models performed better than models using conventional statistical methods in both ROC curves. The support vector machine(SVM) model with twelve variables introduced was identified as the best predictive model.CONCLUSION By incorporating retreatment serum lipids and serum inflammation markers, it is feasible to develop ML-based models for the preoperative prediction of r NACT and therefore facilitate the choice of treatment, particularly the SVM, which can improve the prediction of r NACT in patients with breast cancer.展开更多

Methods: Of the 51 patients with advanced pancreatic cancer receiving chemotherapy with gemcitabine and 5-fluorouracil, 25 patients were treated with selective con-tinuous transarterial infusion chemotherapy, 26 were treated with systemic venous chemotherapy, and curative effective-ness was analyzed retrospectively. Curative effectiveness included tumor volume, clinical benefit response (CBR), acute and subacute toxic reactions of antitumor drugs, survival rate and median survival time. Results: The objective effective rate in transarterial group was 32.0% versus 23.1% in systemic group without any significant difference (P = 0.475). Clinical benefit rates in transarterial group and systemic group were 80.0% and 50.0% respectively (P = 0.025). The 6-, 9-and 12-month accumulated survival rates and median survival time in transarterial group were higher than those of the systemic group (P = 0.002), the differences were statistically significant. However, the adverse reactions between the two groups were not statistically significant. Conclusion: Compared with systemic chemotherapy, continuous transarterial infusion chemotherapy with gemcitabine and 5-fluorouracil could improve clinical benefit rate and survival time of patients with advanced pancreatic cancer, it is safe and reliable, and the adverse reactions is less.展开更多

Accordingly, therehas been a growing interest in alternative approaches with less morbidity,including the organ-preserving watch and wait strategy, in which surgery isomitted in patients who have achieved a cCR. These patients are managed with aspecific follow-up protocol to ensure adequate cancer control, including the earlyidentification of recurrent disease. However, there are several open questionsabout this strategy, including patient selection, the clinical and radiologicalcriteria to accurately determine cCR, the duration of neoadjuvant treatment, therole of dose intensification (chemotherapy and/or radiotherapy), optimal followupprotocols, and the future perspectives of this approach. In the present review,we summarize the available evidence on the watch and wait strategy in thisclinical scenario, including ongoing clinical trials, QoL in these patients, and thecontroversies surrounding this treatment approach.展开更多

Methods Moderate to advanced chronic periodontitis ( CP) was studied in 36 diabetes mellitus (DM) patients classified as 20 with high and fluctuating blood glucose level (DM-H) and 16 with relatively low and stable blood glucose level (DM-L). 28 non-DM CP patients acted as controls (Non-DM). Plaque index (PlI) , gingival index (GI) , bleeding on probing (BOP) , probing depth (PD) and clinical attachment loss (AL) of all patients were recorded at 6 sites on each tooth at the baseline and 1, 3 and 6 months after oral hygiene instruction (OHI), scaling and root planing. Results It was found that the short-term effect of non-surgical periodon-tal procedure had resulted in significant resolution of gingival inflammation and pronounced reduction in pocket depth and gain of attachment loss in both DM and Non-DM CP patients. Conclusion The pilot study suggested that non-surgical periodontal treatment allowed for favorable treatment responses in a group of Chinese diabetic subjects with chronic periodontitis and that their various profiles of blood glucose did not influence the short-term healing response to OHI, scaling and root planning.展开更多
