RESUMO
Objective To explore the value of terminal ileum suspension in the treatment of low rectal cancer.Methods 80 patients with low rectal cancer who underwent laparoscopic operation in our hospital from June 2015 to February 2017,were randomly divided into two groups:the control group (group C) and the test group (group T),40 cases in each group.In group C,laparoscopic radical resection of rectal cancer (Dixon) was performed and in group T Dixon was combined with terminal ileum suspension.Peripheral blood nutritional indicators (total plasma protein,albumin,pre-albumin,transferrin) and major electrolytes of two groups were observed 1 day before operation and 1,3 and 7 days after operation.The two groups were compared in terms of first exhaust time,postoperative hospital stay,total costs for hospitalization,postoperative discomforts and complications.Results There were no statistical differences in the levels of nutrition indicators and electrolytes between them (P ＞ 0.05) and neither it was with first exhaust time,hospital stay,total costs of hospitalization,incidence of postoperative discomforts and complications (P ＞ 0.05).The re-operation rate of group T with anastomotic leak was significantly lower than group C (P ＜ 0.05).Conclusion Terminal ileal suspension does not affect patients' postoperative recovery without increasing the patient's suffering and economic burden,and can effectively reduce the reoperation rate caused by anastomotic leak.It is easy to operate.
RESUMO
Objective To evaluate dendritic cell vaccine immunotherapy in postoperative colorectal cancer patients. Methods 40 colorectal cancer patients were divided into two groups. Group A was not treated with the dendritic cell vaccine after chemotherapy, Group B was treated with four courses of autologous dendritic cell vaccine. The level of cytokines was tested before and after the therapy in both groups. DTH were tested after the last course of treatment. Results The levels of cytokines significantly increased in group B after vaccination compared with that in group B before vaccination and that in group A.8 patients were DTH positive in 15 patients that were tested after the vaccination. The PTS (progression-free survival) was 22 months in group B compared with 17 months in group A. The recurrence of the disease was not observed in patients with DTH positive. Conclusion DC vaccine in postoperative colorectal cancer patients improves the immune status and elicits tumor-specific response.
RESUMO
Objective To evaluate clinical outcome in postoperative patients with advanced gastric cancer treated with concurrent chemotherapy and dendritic cells (DCs) vaccine as well as alteration of immune function. Methods Sixty-four postoperative patients with advance gastric cancer were divided into control group and DC vaccine group, In control group, 38 patients were treated with LCH regimen consisted of 5-fluorouracil 0.75 g/d_(1-5) and oxaliplatin 0.2 g/d_1. In DC vaccine group,blood sample was obtained from 26 patients who were followed by LCH regimen treatment next day.One week after the chemotherapy, patients were immunized with DC vaccine for 2 times at interval of one week. The second cycle was performed after 28 days. The percentages of T lymphocytes and natural killer (NK) cells and cytokine levels before and after treatment were compared between two groups. The therapeutic effects (including no remote metastasis and enlarged lymph nodes in cavity and/or tumor reduced in volume) were also evaluated. Results The concentrations of T lymphocytes (CD3~+ and CD4~+ ), NK cells, interleukin (IL)-2, IL-12 and interferon-γ in DC vaccine group were significantly increased after vaccination compared with those before vaccination (P＜0.05), and even higher than those in control group (P＜0.05). The effective rate was higher in DC vaccine group (80. 76%) than that in control group (68.42%) with significant difference (P＜0. 05). The side effects of chemotherapy such as the decreased peripheral white blood ceils and immune cells were less serious in DC vaccine group compared with control group (P＜ 0.05), while the uncomfortable incidence of gastrointestinal tract and peripheral neuritis showed no significant difference between two groups (P＞0.05). Conclusions Application of concurrent chemotherapy and DC vaccine in patients with advanced gastric cancer after surgical treatment may achieve a short-term efficacy, meanwhile it can reduce the side effects induced by chemotherapy.
