香菇多糖治疗肺癌的临床与实验研究   总被引:5,自引:0,他引:5  
用病例配对法对化疗和化疗加香菇多糖治疗反应进行检测。结果表明香菇多糖对机体的一般状况(KPS法)、大颗粒淋巴细胞(LGL)比率、单细胞比率(M)、T细胞亚群中的CD3、CD4、CD4/CD8均有一定的升高作用。说明香菇多糖(Lentinan)作为一种生物反应调节剂,能促进免疫功能活性细胞增加,对患者化疗后免疫功能具有调节保护作用。  相似文献

香菇多糖对恶性血液病患者免疫功能的初步临床观察   总被引:3,自引:0,他引:3  
随机将62例恶性血液病患者分为两组,一组应用香菇多糖配合化学治疗(42例);另一组单纯应用化疗(20例)。进行对比观察两组患者细胞免疫功能变化及临床治疗效果。结果:香菇多糖治疗后CD4、CD4/CD8及NK细胞活性明显提高(P<0.05),而CD8、HLA-DR抗原活性降低(P<0.05);并且临床有效率及患者红细胞、白细胞亦高于化疗组(P<0.05)。观察用香菇多糖的患者仅有个别出现轻微副反应,通过研究证明香菇多糖能提高恶性血液病免疫功能及化疗效果  相似文献

用国产香菇多糖(天地欣)配合化疗治疗中晚期胃肠道腺癌40例与32例未加用香菇多糖的同种治疗病例比较发现,香菇多糖对增强患者的免疫功能很有效(P<0.01),短期内对提高化疗的总缓解率帮助不大(P>0.05),对降低化疗的毒副反应及改善生活质量有一定影响。香菇多糖(天地欣)的毒副反应小,疗效确切。  相似文献

背景与目的 香菇多糖作为一种生物免疫调节剂日益受到药学界与临床的广泛重视,目前中国和日本都将其作为一种抗肿瘤辅助药品广泛应用。本研究旨在观察香菇多糖联合化疗治疗Ⅲ、Ⅳ期非小细胞肺癌的治疗效果。方法 81例Ⅲ、Ⅳ期非小细胞肺癌患者随机分为A、B两组,A组(42例)采用香菇多糖加化疗,B组(39例)采用单纯化疗。两组患者在治疗前后测定外周血T淋巴细胞亚群(CD3、CD4、CD4/CDR)和NK细胞活性,并以正常人(30例)作为对照,对患者疗效、免疫功能、生活质量及不良反应进行评价。结果 治疗后A、B两组的有效率分别为50%和33%(P<0.05);A组的T淋巴细胞亚群和NK细胞活性明显高于治疗前(P<0.01),CDR明显低于治疗前(P<0.05),而B组无明显变化(P〉0.05);A组的Karnofsky评分上升率(52%)高于B组(23%)(P〈0.01);B组的Ⅱ~Ⅳ度白细胞减少及恶心呕吐反应发生率(分别为51和44例次)高于A组(分别为39和24例次)(P<0.05)。结论香菇多糖联合化疗治疗Ⅲ、Ⅳ期非小细胞肺癌的疗效优于单纯化疗。  相似文献

术后随机将30例胃癌患者分为两组,每组15例。两组性别、年龄、术前肿瘤类型、TNM分期以及手术方式是类似的。用双盲对照法于化疗期间两组分别服用PSP和鲨肝醇,并于化疗前后检测外周血NK细胞活性和T细胞亚群。结果显示;鲨肝醇组化疗对患者免疫功能有明显损害作用。表现在NK细胞活性、细胞、细胞值均明显下降(P<0.05),免疫抑制的细胞上升。服用PSP组能减轻化疗对患者免疫功能的损害,化疗后其NK细胞活性、细胞、细胞值虽有下降,但无显示差异(P>0.05),在两个疗程化疗期间继续服用可明显提高NK细胞活性及细胞和细胞值,说明PSP在提高患者免疫功能,增加患者对化疗的耐受性及提高化疗效果等方面有明显效果。  相似文献

AIM: To examine whether administration of lentinan, purified β-1, 3-glucan, can prolong survival in advanced gastric cancer patients receiving S-1-based chemotherapy.METHODS: Since 2004, 78 patients with metastatic or recurrent gastric cancer have received S-1-based chemotherapy as first-line treatment. Survival, side effects, and the ratio of granulocytes/lymphocytes (G/L ratio) were compared between 2 groups of patients who received chemo-immunotherapy using lentinan and chemotherapy alone.RESULTS: Median overall survival was significantly longer in the former group than in the latter group [689 d (95% CI: 431-2339 d) vs 565 d (95% CI: 323-662 d), P = 0.0406]. In addition, the G/L ratio in patients who received lentinan was maintained around or below 2, which was significantly lower than that in patients who received chemotherapy alone (P < 0.001).CONCLUSION: Chemo-immunotherapy with lentinan offers a significant advantage over S-1-based chemotherapy alone in terms of survival in patients with advanced gastric cancer.  相似文献

Lentinan, an antitumor polysaccharide used clinically in Japan, requires the intact T cell compartment to manifest its antitumor effects. The aim of the current study was to clarify the mechanisms playing crucial roles in the T cell requirement in the expression of antitumor effects of lentinan. Lentinan treatment of BDF1 mice transplanted intradermally with FBL-3 induced complete tumor regression and a marked increase in survival time. The antitumor action of lentinan was abolished in mice treated simultaneously with antibodies to CD4 and CD8 antigens, whereas antibody to CD4, CD8 or NK1.1 alone was ineffective. The natural killer, cytotoxic T lymphocyte, and helper T cell activities were already augmented in this FBL-3/BDF1 system and thus further augmentation of these activities by lentinan was not observed. These activities did not correlate with the antitumor activity of lentinan, as was confirmed in lymphocyte subset depletion experiments. On the contrary, the delayed-type hypersensitivity (DTH) response against tumor-associated antigens was triggered by lentinan and was abrogated only in mice treated simultaneously with antibodies to CD4 and CD8 antigens. Furthermore, a non-cytolytic tumor-associated antigen-specific CD4+ T cell clone able to induce the DTH response in concert with lentinan reconstituted the antitumor effects in B6 nude mice when administered with lentinan. These results suggest that, in addition to the augmentation of immune effector cell activity against tumors, infiltration of these cells into the tumor burden initiated by the DTH responses at tumor sites may be involved in eradication of tumors by lentinan.  相似文献

The antimetastatic activity of a combination of lentinan and interleukin 2 (IL-2) was evaluated against spontaneously metastatic 3-methylcholanthrene-induced DBA/2.MC.CS.T fibrosarcoma. Although pre-operative treatment with either IL-2 or lentinan alone exerted little effect on the reduction of lung metastasis colony numbers (7.1% or 28.4% reduction, respectively), the combination exhibited a synergistic effect (85% reduction). Furthermore, 3 of 13 mice given the pre-operative combination treatment achieved complete cure, while no mice given saline did. Although the post-operative combination treatment also reduced the colony number (71% reduction), it caused little prolongation of survival and no mouse achieved complete cure. Synergistic effects were observed between pre- and post-operative treatments with lentinan and IL-2: 8 of 12 mice were completely cured. The anti-metastatic activity was abolished in mice treated simultaneously with antibodies to CD4 and CDS antigens, whereas either CD4, CDS, or NK1.1 antibody alone was ineffective. Analysis of the cellular mechanism involved in the antimetastatic activity revealed the involvement of a tumor-associated antigen-specific delayed-type hypersensitivity response. These data suggest that the life-prolonging effect of the combination of lentinan and IL-2 is mediated by antigen-specific T cells and that the combination of pre- and post-operative therapy with lentinan and IL-2 may be effective to prevent cancer recurrence and metastasis after surgical resection.  相似文献

We examined the usefulness of preoperative chemotherapy using 5-FU and low-dose CDDP in patients with stage IVb gastric cancer. Between 1996 and 1998, seven patients with stage IVb gastric cancer who received preoperative chemotherapy achieved complete or partial response. One course of the chemotherapy was as follows: arterial or venous infusion of 5-FU (500 or 250 mg/day on day 1-5) and low-dose CDDP (5-10 mg/day on day 1-5) for three weeks. In addition to preoperative chemotherapy, biological response modifiers such as OK-432 and lentinan were used. We evaluated the response with abdominal or chest CT and tumor markers. Although preoperative chemotherapy did not improve the survival rate significantly, the prognosis of these patients seemed to be relatively good. Only slight side effects were found. These results suggest that preoperative chemotherapy using 5-FU and low-dose CDDP may be useful for patients with stage IVb gastric cancer.  相似文献

61 patients with inoperable non-small cell lung cancer were treated by combination chemotherapy with cisplatin, Adriamycin and cyclophosphamide. 23 patients received radiotherapy in addition to the chemotherapy. 49 out of 55 adequately treated patients were evaluable for tumor response. Of 29 patients who received chemotherapy alone, 6 (21%) achieved partial responses. Of 20 patients who received combined chemotherapy and radiotherapy, 16 (80%) achieved complete or partial responses. The median survival time was 18 months for 22 patients treated with combined therapies.  相似文献

Lentinan; i.e., polysaccharides extracted from a kind of black mushroom shiitake, has been clinically applied as an antitumor and antimetastatic drug, and has been reported to prevent both chemical and viral carcinogenesis. It is known that lentinan affects the tumorous vascular system resulting in the induction of hemorrhagic necrosis which is dependent on T-cells in the tumor. Repeated mucosal necrosis-regeneration sequence in chronic ulcerative colitis induced with 3% dextran sulfate sodium led to colorectal carcinogenesis in azoxymethane-pretreated mice. In the present study, the additive treatment with lentinan in the azoxymethane-dextran sulfate sodium treated mice enhanced the colorectal high-grade dysplasia, though not significantly, and the splenic weight. This may show the proliferation of pathogenic splenic T cells resulting in a change for the worse of ulcerative colitis, anemia induced with hemorrhage and colorectal carcinogenesis; i.e., high-grade dysplasia of the mucosa and/or invasive adenocarcinomas of the colorectum. The present results may recommend chemoimmunotherapy while using lentinan, but not immunotherapy using lentinan alone, is indicated for the management of cancer patients.  相似文献
