Abstract
The safety and efficacy of combination therapy of immune cell therapy and chemotherapy [chemo-adoptive immunotherapy (CAIT)] for patients with stage IV or recurrent colorectal cancer have been reported. In the present study, the safety and efficacy of neoadjuvant CAIT were investigated for preoperative therapy of locally advanced rectal cancer. The study included patients with cT3/T4 or cN (+) rectal adenocarcinoma scheduled for curative surgery. Six patients who consented to participate in the current study were selected as subjects. Neoadjuvant CAIT involves administration of activated autologous lymphocytes, αβ T cells, and mFOLFOX6 every 2 weeks for six courses, followed by surgery 4-6 weeks thereafter. Common Terminology Criteria for Adverse Events grade 3 neutropenia was observed in one patient. Neoadjuvant CAIT and curative surgery were performed on all the patients. The confirmed response rate was 67%. Downstaging was confirmed in five patients (83%). Regarding histological effects, two patients were grade 1a and four were grade 2. Regarding immunological reactions, both CD4+ and CD8+ T cell infiltration rates increased after treatment in three patients on tumor-infiltrating lymphocyte (TIL) analysis. In peripheral blood analysis, the total lymphocyte count was maintained in all patients, and the CD8+ T cell count increased by ≥3 times on the pretreatment count in two patients but may not be associated with changes in TILs. During the median postoperative follow-up duration of 24 months, liver and lung metastases occurred in one patient, but all patients survived. In conclusion, neoadjuvant CAIT (αβ T cells + mFOLFOX6) can be safely administered for the treatment of advanced rectal cancer. Verification of the efficacy of comprehensive immune cell therapy, especially the induction of antitumor immunity for the prevention of recurrence, will be maintained. The current study is registered with the Japan Registry of Clinical Trials (jRCT; ID, jRCTc030190248; January 21, 2019).

Abstract
BACKGROUND AIMS With the aim of strengthening the scientific evidence of immune-cell therapy for cancer and further examining its safety, in October 2015, our hospital jointly established the Cancer Immune-Cell Therapy Evaluation Group (CITEG) with 39 medical facilities nationwide. METHODS Medical information, such as patients' background characteristics, clinical efficacy and therapeutic cell types obtained from each facility, has been accumulated, analyzed and evaluated by CITEG. In this prospective study, we analyzed the adverse events associated with immune-cell therapy until the end of September 2022, and we presented our interim safety evaluation. RESULTS A total of 3839 patients with malignant tumor were treated with immune-cell therapy, with a median age of 64 years (range, 13-97 years) and a male-to-female ratio of 1:1.08 (1846:1993). Most patients' performance status was 0 or 1 (86.8%) at the first visit, and 3234 cases (84.2%) were advanced or recurrent cases, which accounted for the majority. The total number of administrations reported in CITEG was 31890, of which 960 (3.0%) showed adverse events. The numbers of adverse events caused by treatment were 363 (1.8%) of 19661 administrations of αβT cell therapy, 9 of 845 administrations of γδT-cell therapy (1.1%) and 10 of 626 administrations of natural killer cell therapy (1.6%). The number of adverse events caused by dendritic cell (DC) vaccine therapy was 578 of 10748 administrations (5.4%), which was significantly larger than those for other treatments. Multivariate analysis revealed that αβT cell therapy had a significantly greater risk of adverse events at performance status 1 or higher, and patients younger than 64 years, women or adjuvant immune-cell therapy had a greater risk of adverse events in DC vaccine therapy. Injection-site reactions were the most frequently reported adverse events, with 449 events, the majority of which were associated with DC vaccine therapy. Among all other adverse events, fever (228 events), fatigue (141 events) and itching (131 events) were frequently reported. In contrast, three patients had adverse events (fever, abdominal pain and interstitial pneumonia) that required hospitalization, although they were weakly related to this therapy; rather, it was considered to be the effect of treatment for the primary disease. CONCLUSIONS Immune-cell therapy for cancer was considered to be a safe treatment without serious adverse events.

Abstract
BACKGROUND/AIM The efficacy of adjuvant systemic therapy after surgical resection remains unsatisfactory; therefore, a new treatment strategy is required. We aimed to examine the efficacy of adjuvant immune-cell therapy using activated T lymphocytes with or without dendritic cell vaccination in combination with standard adjuvant systemic therapies in terms of the survival of patients with solid tumors, such as lung, gastric, pancreatic, colorectal, and breast cancers. PATIENTS AND METHODS A total of 141 patients with solid tumors were enrolled in this study. The correlation of overall survival and disease-free survival with various clinical factors such as age, sex, performance status score, clinical stage, treatment strategies, and vital status was investigated by univariate and multivariate analyses. RESULTS Multivariate analysis revealed that a performance status score of 0 was a favorable prognostic factor in the full analysis set of solid tumors (HR=0.209, 95%CI=0.065-0.676, p=0.0089) and might be the indication for immune-cell therapy in the adjuvant setting. CONCLUSION Adjuvant immune-cell therapy combined with other systemic therapies would potentially provide a survival benefit in patients with solid tumors.

Abstract
BACKGROUND/AIM Advanced/recurrent breast cancer (ARBC) still has a poor prognosis; therefore, new treatment strategies are required. In this retrospective study, we aimed to investigate the efficacy of immune-cell therapy using T lymphocytes activated in vitro with or without dendritic cell vaccination in combination with standard therapies in terms of the survival of patients with ARBC. PATIENTS AND METHODS A total of 127 patients with ARBC were enrolled in this study. The correlation between overall survival and various clinical factors of each ARBC subset was examined by univariate and multivariate analyses. RESULTS Multivariate analysis demonstrated that performance status (PS) 0, the absence of prior chemotherapy, liver/pleural metastasis, and the presence of combined surgery in ARBC and PS 0 or the absence of liver metastasis in the HR+/HER- subset are indications for immune-cell therapy. CONCLUSION A survival benefit could be potentially obtained by a combination of immune-cell therapy with other therapies in ARBC patients.

Abstract
Background Blocking the programmed death 1 pathway by immune checkpoint inhibitors induces dramatic antitumor activity in patients with malignant tumors. However, the clinical response to immune checkpoint inhibitors remains limited owing to the patients’ immunological status, such as the number of lymphocytes, programmed death ligand 1 expression, and tumor mutation burden. In this study, we successfully treated two patients with advanced esophageal cancer who responded to the combination of adoptive immune cell therapy and a low-dose immune checkpoint inhibitor, nivolumab. Case presentation Two Asian (Japanese) patients with advanced esophageal cancer who were resistant to conventional chemoradiation therapy were referred to our hospital for immune therapy. Case 1 was a 66-year-old woman who was diagnosed as having esophageal cancer. She received concurrent chemoradiation therapy and then underwent subtotal esophagectomy, after which she became cancer free. However, she relapsed, and cancer cells were found in the lung and lymph nodes 6 months later. She enrolled in a clinical trial at our institution (clinical trial number UMIN000028756). She received adoptive immune cell therapy twice at a 2-week interval followed by low-dose nivolumab with adoptive immune cell therapy four times at 2-week intervals. A follow-up computed tomography scan showed partial response, with mass reduction of the metastatic lung and mediastinal lesions. Case 2 was a 77-year-old man. He received concurrent chemoradiation therapy with fluoropyrimidine/platinum, and gastroscopy revealed complete remission of esophageal cancer. He was disease free for 5 months, but routine computed tomography revealed multiple metastases in his lungs and lymph nodes. He visited our clinic to receive adoptive immune cell therapy and immune checkpoint inhibitor combination therapy. Radiographic evidence showed continuous improvement of lesions. There was no evidence of severe adverse events during the combination therapy. Conclusion The combination of adoptive immune cell therapy and an immune checkpoint inhibitor might be a possible treatment strategy for advanced esophageal cancer. Trial registration UMIN000028756.

Abstract
BACKGROUND/AIM In this retrospective study, we aimed to investigate the efficacy of immune-cell therapy using T lymphocytes activated in vitro with or without dendritic cell vaccination in combination with standard therapies in terms of the survival of patients with advanced or recurrent endometrial and cervical cancers of the uterus. PATIENTS AND METHODS A total of 187 patients with advanced or recurrent uterine cancer were enrolled in this study. The correlation between overall survival and various clinical factors was examined by univariate and multivariate analyses. RESULTS Univariate analysis revealed that the prognosis was improved in uterine cancer patients who received immune-cell therapy without prior chemotherapy or without distant metastasis. Multivariate analysis demonstrated that the absence of prior chemotherapy for endometrial cancer and liver/lung metastasis of cervical cancer are indications for immune-cell therapy. CONCLUSION Survival benefit in uterine cancer patients could be potentially obtained by a combination of immune-cell therapy with other therapies.

Abstract
BACKGROUND AIMS Activated γδT cells have been shown to exhibit cytotoxicity against tumor cells. However, the efficacy of γδT cell immunotherapy for a large number of patients with solid tumors remains unclear. In this study, we examined the efficacy of γδT cell immunotherapy using in vitro-activated γδT lymphocytes in combination with standard therapies in terms of the survival of patients with solid tumors, and determined prognostic factor for γδT cell immunotherapy. METHODS 131 patients enrolled in this study received γδT cell immunotherapy with or without standard therapies. Their overall survival was analyzed by the Kaplan-Meier with log-rank test and Cox regression methods. Immunological analysis was performed by flow cytometry (FCM) before and after six cycles of γδT cell immunotherapy. RESULTS Multivariable analysis revealed that patients who showed stable disease (SD) and partial response (PR) to γδT cell immunotherapy showed better prognosis than those with a progressive disease (PD) (P = 0.0269, hazard ratio [HR], 0.410, 95% confidence interval [CI], 0.190-0.901). Furthermore, when immunological parameters were examined by FCM, the high Vγ9/γδT ratio (i.e., the high purity of the Vγ9 cells within the adoptively transferred γδT cells) before treatment was found to be a good prognostic factor for γδT cell immunotherapy (P = 0.0142, HR, 0.328, 95% CI, 0.125-0.801). No serious adverse events were reported during γδT cell immunotherapy. CONCLUSION Thus, γδT cell immunotherapy might extend the survival of patients with solid tumors.

Abstract
BACKGROUND/AIM In this retrospective study, we aimed to investigate the efficacy of immune-cell therapy using T lymphocytes activated in vitro with or without dendritic cells vaccination (DCs), in combination with 1st-line chemotherapies in terms of the survival of patients with advanced colorectal cancer (CRC). PATIENTS AND METHODS A total of 198 patients who were diagnosed with advanced CRC and administered 1st-line chemotherapies were enrolled in this study. The correlation between overall survival (OS) and various clinical factors was examined by univariate and multivariate analyses. RESULTS Univariate analyses revealed that the prognosis was improved in CRC patients who received immune-cell therapy with PS 0, bevacizumab (BV), and capecitabine-including regimens (Cap). Finally, multivariate analysis demonstrated that PS=0, and the combination of immune-cell therapy and Cap provided a survival benefit in patients with advanced CRC. CONCLUSION The survival benefit could be potentially obtained with better PS by the combination of immune-cell therapy and Cap as a 1st-line setting in patients with CRC.

Abstract
BACKGROUND/AIM The past 17 years, immune-cell therapy has been administered to 990 patients with advanced or recurrent pancreatic adenocarcinoma and 50 patients with curatively resected pancreatic adenocarcinoma. MATERIALS AND METHODS The correlation between overall survival (OS) and various factors including sex, age, performance status (PS), distant metastasis, chemotherapy, radiotherapy, and type of immune-cell therapy were evaluated by univariate and multivariate analyses. RESULTS The median OS of advanced or recurrent pancreatic cancer was 5.8 months, and the prognosis was improved in pancreatic cancer patients who received immune-cell therapy with PS scores of 0-1 [hazard risk (HR)=0.56; 95% confidence interval (CI)=0.46-0.68; p<0.0001], chemotherapy (HR=0.68; 95%CI=0.54-0.87; p=0.002), or radiotherapy (HR=0.76; 95%CI=0.63-0.93; p=0.006). Multivariate analysis demonstrated that distant metastasis indicated a poor prognosis for pancreatic cancer patients that were administered immune-cell therapy (HR=1.62; 95%CI=1.37-1.93; p<0.0001). Additionally, the combined immune-cell therapy with αβ T cell and dendritic cell (DC) vaccine provided a survival benefit in advanced or recurrent pancreatic cancer patients (HR=0.69; 95%CI=0.57-0.83; p<0.0001). CONCLUSION A survival benefit could be potentially obtained with better PS by the combination of αβ T cell therapy, DC vaccine therapy, and chemotherapy at an early stage in pancreatic cancer.

Abstract
BACKGROUND Conventional therapy for advanced gastric cancer (GC) has limited survival benefits. In this retrospective study, we aimed to investigate the efficacy of immune-cell therapy, using in vitro-activated T-lymphocytes with and without dendritic cells (DCs), in combination with standard therapies in terms of the survival of patients with advanced GC. PATIENTS AND METHODS A total of 242 patients who were diagnosed as having stage-IV GC were enrolled in this study to receive immune-cell therapy with or without standard therapies, such as chemotherapy, surgery, or radiation therapy. Overall survival was analyzed by the Kaplan-Meier with log-rank test and Cox regression methods. RESULTS Immune-cell therapy increased median survival time (21.5 months) in patients with advanced GC. The patients who underwent surgery with or without chemotherapy as a prior treatment showed better prognosis than those who received other therapies (p<0.001). Patients who showed stable disease or a partial response to immune-cell therapy had a better prognosis than those with progressive disease (p<0.001). Multivariate analysis revealed that performance status, the type of immune-cell therapy, and prior treatment were independent prognostic factors for patients with GC. No serious adverse event was reported in immune-cell therapy. CONCLUSION Immune-cell therapy might extend the survival of patients with advanced GC.

Abstract
For a peptide-pulsed dendritic cell (DC) vaccine to work effectively in cancer treatment, it is significant that the target protein is expressed in cancer cells. Wilms' tumor 1 (WT1) has been identified as a molecular target for immune cell therapy of cancer. We evaluated the protein expression levels of WT1 in various solid tumors, as well as mucin 1 (MUC1) or major histocompatibility complex (MHC) class l molecules. Seven hundred and thirty-eight patients whose tissue samples were examined by immunohistochemical analysis agreed to undergo DC vaccine therapy. The positive staining of WT1 in tumor cells was observed in 25.3% of patients, with only 8.5% of them showing moderate to strong expression; moreover, WT1 tended to localize in the nucleus and cytoplasm. A positive staining of tumor cells by an anti-MHC class l monoclonal antibody was observed in 98.6% and by an anti-MUC1 monoclonal antibody in 76.8% of the patients. In relation to the application of cancer-specific immunotherapy, these findings provide useful information for determining the efficacy of MUC1- and WT1-targeted therapy.

Abstract
We evaluated the immunological status of patients with various solid tumors by flow cytometry of immune cell populations and their frequencies in peripheral blood samples. The change in immunological status was also analyzed in patients given autologous immune cell therapy, such as αβT cell, γδT cell, NK cell or DC vaccine therapy. The frequency of regulatory T-cells (Tregs) was shown to be high in patients with cancers of the lung (squamous carcinoma cells), head and neck, esophagus and uterus, although there were no significant differences in effector cell population or Th1/2 ratio between various types of cancers except for a few. The cellular immunological status was impaired in most patients with advanced solid tumors before immune cell therapy and the impaired T-cell immune status was restored by infusion of effector cells, such as αβT cells or γδT cells, although the number of NK cells in the peripheral blood did not always increase after autologous NK cell therapy. The concurrent αβT cell therapy and DC vaccine therapy could successfully increase the number of CD8(+) T-cells in the peripheral blood of patients with various types of cancers. Two or three injections of αβT cells could potentially reduce Tregs frequency prior to DC vaccine, as well as the concurrent αβT cell and DC vaccine therapy. However, an increase in the Tregs frequency was observed in some patients who received NK cell therapy. These findings suggest that it is necessary to include or combine certain types of immune cell therapy when the Tregs frequency of cancer patients is high before or after autologous immune cell therapy.

Abstract
Several types of immune-cell therapies, such as αβ T-cell, γδ T-cell, and dendritic cell (DC) vaccine therapies, are clinically employed for cancer treatment. The safety of immune-cell therapy for the treatment of patients with malignancies should be maintained by continuous assessment of adverse events. In the present study, we surveyed the adverse events associated with immune-cell therapy using large-scale prospective data and analyzed the side-effect profiles. For the assessment of adverse events associated with immune-cell therapy, we evaluated 771 treatment profiles (484 for αβ T-cell therapy, 58 for γδ T-cell therapy, 206 for DC vaccine therapy, and 23 for concurrent therapy with αβ T-cells and DC vaccines) from 144 patients with various malignancies. For the assessment of fever, fatigue, and itching, each of these adverse events was found to be grade 1 or 2 in most of the treated patients, except for one patient who had grade 3 itching. It was suggested that αβ T-cell therapy could elicit a more rapid and direct immune reaction in patients than DC vaccine therapy, as shown by the earlier development of fever and higher incidence rate of fatigue. It was found that grade 1 or 2 reaction at the injection site developed in 10.2% of the patients injected with DC vaccines. Most of the grade 3 non-hematological and hematological adverse events were associated with disease progression or side-effects of chemotherapy, and were not considered to be related to immune-cell therapy. In conclusion, immune-cell therapy, such as αβ T-cell, γδ T-cell, or DC vaccine therapy, was well-tolerated for cancer treatment.

Abstract
Dendritic cell (DC)-based vaccines with the use of various antigen loading methods have been developed for cancer immunotherapy. Electroporation (EP) of a whole tumor cell lysate into DCs was previously found to be more potent for eliciting antigen-specific CD8 + T-cells compared to co-incubation of tumor cell lysates with DCs in vitro. In the present report, we studied the feasibility, safety and antitumor effect in the clinical use of an EP-DC vaccine for the immunotherapy of various types of human solid tumors. We successfully prepared an autologous tumor lysate-loaded EP-DC vaccine with high cell viability by the closed-flow electroporation system. In the phase I clinical trial, mild adverse events associated with the EP-DC vaccine were found during the treatment of advanced or recurrent cancer, or during the adjuvant therapy of some types of cancer; no autoimmune responses were observed after treatment with the autologous tumor lysate-loaded EP-DC vaccines. For the antitumor effect of the EP-DC vaccine against the 41 various types of solid tumor, the overall response rate [complete remission (CR) + partial response (PR)] was 4.9% (2/41) and the clinical benefit rate [CR+ PR + long stable disease (SD)] was 31.7% (13/41). Furthermore, the delayed-type hypersensitivity (DTH) reactivity was positive in most cases of long SD and the positive rate of DTH was 91.7% (11/12) for the patients with clinical benefit. In conclusion, the safety and feasibility of the EP-DC vaccine with autologous tumor lysates were confirmed, and it was found that the antitumor effect might be associated with the immunological response induced by the EP-DC vaccine for cancer immunotherapy.

Abstract
Abstract
Recently, the practical research and development of SB latex for a cement modifier have taken place and the cement mortars so modified are used in the field of building or civil engineering. The physical and chemical properties of SB latex-modified mortars have already been reported, but the effects of various polymerization conditions for latex synthesis on properties of SB latex-modified mortars have hardly been noticed. The authors discuss the effects of polymerization conditions, in particular, styrene/butadiene monomer ratio on physical properties of SB latex-modified mortar and conclude that the physical properties such as strength, drying shrinkage, adhesion, abrasion and shock resistance, etc., of SB latex-modified mortars are affected more intensely by the variation of bound styrene contents than by the rubber-cement ratios.
