This first-in-human study evaluated the safety, pharmacokinetics,tolerability and preliminary anti-tumor activity of Hemay022 in HER2-positive advanced breast cancer patients.Methods: Heavily pretreated patients with HER2-positive advanced breast cancer were assigned to eight dose cohorts in a 3+3 dose-escalation pattern at doses of 50-600 mg QD and 300 mg BID. Eligible patients were given a single dose of Hemay022 on d 1 in week 0, followed by once daily continuous doses for four weeks in 28-day cycles.Pharmacokinetic samples were obtained on d 1 and d 28. Clinical responses were assessed every eight weeks.Results: Twenty-eight patients with advanced breast cancer were treated with Hemay022. The most frequently reported drug-related adverse events were diarrhoea(85.7%), vomiting(28.6%), nausea(25.0%) and decreased appetite(17.9%). No grade 4 drug-related adverse events were reported. At 50-600 mg doses, steady state areas under the concentration-time curve and peak concentrations increased with doses. One patient achieved complete response(CR), and three achieved partial response(PR). The objective response rate(ORR) and disease control rate(DCR) were 14.3% and 46.4% in 28 patients, respectively. The median progression-free survival(PFS) was3.98 months.Conclusions: Hemay022 at the dose of 500 mg once daily was well tolerated. The pharmacokinetic properties and encouraging anti-tumor activities of Hemay022 in advanced breast cancer patients warranted further evaluation of Hemay022 for treating breast cancer patients in the current phase Ⅲ trial(No. NCT05122494).展开更多

Methods: Patients with advanced bladder cancer who were treated in Tongcheng People's Hospital between April 2015 and July 2016 were selected as the research subjects and randomly divided into group A who received interleukin-2 + pirarubicin infusion chemotherapy combined with systemic chemotherapy and the group B who received pirarubicin infusion chemotherapy combined with systemic chemotherapy. The contents of tumor markers and cytokines and the expression of apoptosis molecules in the urine were detected before and after chemotherapy. Results: 8 weeks after chemotherapy, BLCA-1, BLCA-4, CYFRA21-1, TGF-β1, VEGF, EGF, HGF and IGF-2 contents in urine of both groups of patients were significantly lower than those before treatment, Fas, Bad, PTEN and Beclin-1 mRNA expression in urine were significantly higher than those before treatment and BLCA-1, BLCA-4, CYFRA21-1, TGF-β1, VEGF, EGF, HGF and IGF-2 contents in urine of group A were significantly lower than those of group B, Fas, Bad, PTEN and Beclin-1 mRNA expression in urine were significantly higher than those of group B. Conclusion: Interleukin-2+ pirarubicin infusion chemotherapy combined with systemic chemotherapy can be more effective than pirarubicin infusion chemotherapy combined with systemic chemotherapy in inhibiting the malignant biological behavior of advanced bladder cancer.展开更多

Laparoscopic distal gastrectomy (LDG) has been adopted gradually and performed for advanced gastric cancer. However, laparoscopic total gastrectomy (LTG) has not been as widely accepted as LDG due to technical difficulties, especially with reconstruction and proper D2 lymphadenectomy. The purpose of the current study was to determine the utility of TLTG with concomitant splenectomy and D2 lymphadenectomy (TLTGS) for advanced gastric cancer (AGC). Materials and Methods: Between January 2006 and May 2014, 10 consecutive patients who underwent TLTGS for AGC and 76 patients who underwent TLTG with D1 lymphadenectomy were included in this study. These two groups were compared in terms of perioperative results, with assessment of intraoperative and postoperative outcomes. Results: There were no significant differences in patients’ characteristics between the two groups. Operative time was longer in the TLTGS group than in the TLTG group. However, the rate of patients with postoperative complications including major complications was not different between the groups, and no patient in the TLTGS group had anastomotic leakage or pancreatic fistula. Conclusions: In the short-term, TLTGS had good postoperative outcomes and was useful and acceptable for AGC.展开更多

Methods: A total of 78 patients with advanced non-small cell lung cancer who were diagnosed and treated in our hospital between August 2015 and January 2017 were reviewed and then divided into the routine group (n=41) who received chemoradiotherapy alone and the Yiqi Yangyin Prescription group (n=37) who received chemoradiotherapy combined with Yiqi Yangyin Prescription therapy. The differences in serum levels of tumor markers, Th1/Th2 cytokines and Th17/Treg cytokines were compared between the two groups before and after treatment. Results: After treatment, serum tumor markers CA15-3, Cyfra21-1, HSP90 and CEA levels of Yiqi Yangyin Prescription group were lower than those of routine group;serum Th1 cytokines IFN-γ and IL-2 levels were higher than those of routine group while Th2 cytokines IL-4 and IL-5 levels were lower than those of routine group;serum Th17 cytokines IL-17 and IL-23 as well as Treg cytokines IL-10 and TGF-β levels were lower than those of routine group. Conclusion: Routine chemoradiotherapy combined with Yiqi Yangyin Prescription therapy can effectively reduce the tumor load and optimize the anti-tumor immune function in patients with advanced non-small cell lung cancer.展开更多
