Modulated electrohyperthermia(mEHT) is a new hyperthermia technique that induces immunogenic death or apoptosis of pancreatic cancer cells in laboratory experiments and increases tumor response rate and survival in pancreatic cancer patients, offering beneficial therapeutic effects against this severe type of cancer.AIM To assess survival, tumor response and toxicity of mEHT alone or combined with CHT compared with CHT for the treatment of locally advanced or metastatic pancreatic cancer.METHODS This was a retrospective data collection on patients affected by locally advanced or metastatic pancreatic cancer(stage Ⅲ and IV) performed in 9 Italian centers, members of International Clinical Hyperthermia Society-Italian Network. This study included 217 patients, 128(59%) of them were treated with CHT(no-mEHT) and 89(41%) patients received mEHT alone or in association with CHT. mEHT treatments were performed applying a power of 60-150 watts for 40-90 min, simultaneously or within 72 h of administration of CHT.RESULTS Median patients’ age was 67 years(range 31-92 years). mEHT group had a median overall survival greater than non-mEHT group(20 mo, range 1.6-24, vs 9 mo, range 0.4-56.25, P < 0.001). mEHT group showed a higher number of partial responses(45% vs 24%, P = 0.0018) and a lower number of progressions(4% vs 31%, P < 0.001) than the no-mEHT group, at the three months follow-up. Adverse events were observed as mild skin burns in 2.6% of mEHT sessions.CONCLUSION mEHT seems safe and has beneficial effects on survival and tumor response of stage Ⅲ-IV pancreatic tumor treatment. Further randomized studies are warranted to confirm or not these results.展开更多

Based on the preliminary results of a phase I study, this phase Ila study compared the efficacy and safety of different dosage schedules of gambogic acid in patients with advanced malignant tumors. Methods Patients with advanced or metastases cancer who had not received any effective routine conventional treatment or who had failed to respond to the existing conventional treatment were randomly assigned to receive either 45 mg/m2 gambogic acid intravenously from Days 1 to 5 of a 2-week cycle (Group A), or 45 mg/m2 every other day for a total of five times during a 2-week cycle (Group B). The primary endpoint was objective response rate (ORR). Results Twenty-one patients assigned to Group A and 26 to Group B were included in the final analysis. The ORRs were 14.3% in Group A and 0% in Group B. It was not possible to analyze the significant difference because one of the values was zero. The disease control rates (DCRs) were 76.2% in Group A and 61.5% in Group B (P=0.0456). The observed adverse reactions were mostly Grades I and II, and occurred in most patients after administration of the trial drug. There was no significant difference in the incidence of adverse reactions between the two arms. Conclusions The preliminary results of this phase Ila exploratory study suggest that gambogic acid has a favorable safety profile when administered at 45 mg/m2. The DCR was greater in patients receiving gambogic acid on Days 1-5 of a 2-week cycle, but the incidence of adverse reactions was similar irrespective of the administration schedule.展开更多

In order to increase the therapeutical effect, we modified some steps of Rosenberg's approach a. cold digestion with collagenase at 4C for 24 hours; b. sedimentation instead of centrifugation; c. elimination of tumor cells before the cultivation procedure. Compared with the original approach, the proliferation, activity and cytotoxicity of TILs obtained by the modified procedure were much improved. TILs' expansion-old was greater than that with the original approach. Cytotoxicity against rumor cells was more potent. Increased TILs' subsets were CD3 and CD8 cells. Meanwhile, we took tumor cells from tumor tissues to test their in vitro chemosensitivities to different drugs in order to select highly sensitive antitumor drugs for treatment of cases with advanced tumors. According to the design of using highly active TILs and highly sensitive drugs (H & H therapy), preliminary clinical results of 50 cases showed higher response rates than those in treatment with TIL / IL2, LAK / 1L2 and TIL+IL2+CTX. Less toxic side effects were observed in 14 patients.展开更多

According to the design of using highly active TILs and highly sensitive drugs (H & H therapy), preliminary clinical results of 50 cases showed higher response rates than those in treatment with TIL / IL2, LAK / 1L2 and TIL+IL2+CTX. Less toxic side effects were observed in 14 patients.
文摘Aim:Primary tumors can be divided into oncogene-addicted(e.g.,lung)and non-oncogene addicted(e.g.,breast).Only the former group has an Achilles-heel single gene for successful target therapy,whereas the latter has mutations of multiple causative genes.Currently,tissue biopsy used for genetic surveys do not give a complete picture of the molecular profile and clonal evolution,but only provide static information over time.Methods:A series of 133 patients with 16 different solid tumors were enrolled.Blood samples were collected and cell-free DNA(cfDNA)was extracted.cfDNA libraries were analyzed using AVENIO circulating tumor DNA(ctDNA)Expanded Kit and Illumina NextSeq 550 for sequencing was used.In order to evaluate the clinical evolution over time,a second cfDNA analysis was performed after a mean interval of 2 months.Results:Through the cfDNA liquid biopsy,we found 89 pathogenic variants in 54 genes.Breast,lung,and prostate cancers showed the largest number of mutated genes.TP53,PIK3CA,FGFR3,KRAS,and ERBB2 were the most frequently mutated genes among 16 different tumors.Gene distribution didn’t show any type of prevalence.In particular,every patient with disease progression seems to have a“private”combination of gene pair mutations,with TP53 as the most frequently mutated gene.Conclusion:We showed that the clonal evolution of tumors includes a private combination of genes,regardless of tumor type.In the future,the cancer treatment can be the targeted therapy against specific tumor mutation(s).The present approach seems promising to both identify key cancer genes and follow clonal evolution over time.
文摘Objective: To observe the clinical efficacy of Kang'aibao oral liquid (KABL), a Chinese herbal preparation in treating malignant tumor of middle or advanced stage. Methods: A comparative study was done by observing the effect of 103 patients treated with KABL, and another 90 patients treated with chemotherapy at the same time were taken as the control group.Results: The immunologic function, short term effective rate (complete relieved rate and partial relieved rate), survival quality, 1 , 2 and 3 year survival rate, median survival time, and carcinoembryonic antigen (CEA) declining rate of the KABL group were significantly higher than those of the control group. Conclusion: KABL has the effects of inhibiting tumor growth, prolonging survival time and improving survival quality of tumor patients.
