ABSTRACT

Objective To analyze the clinical and pathological factors that affect the prognosis of gastric cancer patients after radical resection,and study the relationship between biological behavior of gastric cancer and clinical so as to provide clues to the basis for clinical diagnosis and treatment.Methods The clinical and pathological data of the gastric cancer patients who underwent radical resection from January 1999 to December 2009 were retrospectively analyzed.Of the 581 eligible patients were followed up in 179 cases.A database was established for SPSS 13.0 software analysis.Results Single factor analysis showed that the prognosis influencing factors in gastric cancer patients after radical resection were age,tumor location,tumor size,gross type,histological type,depth of invasion,TNM stage,surgical procedure,the cancerous remains of specimen surgical margin and the number of lymph node metastasis (P < 0.05 or < 0.01),no correlation was found between gender and prognosis (P > 0.05).Multiple Cox regression analysis showed that TNM stage and number of lymph node metastasis were independent gastric cancer prognostic influencing factors,and the number of lymph node metastasis was found to be the more significant factor.Conclusions TNM stage and the number of lymph node metastasis are independent prognostic influencing factors in gastric cancer,and the number of lymph node metastasis is the more important factor in gastric cancer prognosis.Therefore,Union for International Cancer Control lymph node staging of gastric cancer is a better indicator for gastric cancer prognosis.

ABSTRACT

Objective:The explore the mechanism of active immunotherapy with autologous tumor vaccine and clinical significance.Methods:30 patients with advanced tumors were enrolled in this study.4 weeks after operation,the patients received vaccinations of autologous tumor vaccine every 7~10 days for 4 times as adjuvant active immunotherapy,3 days before and 7 days after administrations:peripheral blood monuclear cells(PBMC) were isolated to assay the alteration of proportions of CD + 8 IFN ? + and CD + 8 IL 10 +,CD + 4 IFN ? + and CD + 4 IL 10 + cells.Meanwhile,serum IFN ? and IL 10 were measured within 48 hours after the skin tests with PPD and autologous tumor antigen,diameters of erythemas or indurations were observed.The clinical follow up was performed.Results:After active immunotherapy with autologous tumor vaccine.①The serum IFN ? was increased from (5.98?2 40)pg/ml to (11.20?4.76) pg/ml(P

ABSTRACT

Tumor infiltrating lymphocytes(TILs) were isolated by enzymatic digestion and discontinuous gradient centrifugation from 8 human advanced tumors (4 stomach carcinoma, 2 liver cancer, 1 non-small-cell lung carcinoma and 1 colon cancer). These cells were cultured in complete RPMI 1640 medium supplemented with l000U/ml of rhIL2 for 4-6 weeks, till the cell number reach over l09/total, reinfused to the same patients i.v. meanwhile, the patients received 105U of rhIL2 i.m for 5 days. One week before and one month after TIL infusion periphery blood from the patients was collected and the mononuclear cells were isolated. Cytotoxicity against a panel of tumor cell targets by MTT colorometric assay and lymphocyte phenotype by two-color flow cytometry were mornitored. The results showed that there was significant increase in the killing ability to the tested tumor targets to different extent, especially the killing to the target cells which shared the same histological type with the patients tumor.
