Tumor microenvironment characteristics association with clinical outcome in patients with resected intestinal-type gastric cancer. Oncologist 2024:oyae124. [PMID: 38907674 DOI: 10.1093/oncolo/oyae124] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Accepted: 05/04/2024] [Indexed: 06/24/2024] Open
Abstract
BACKGROUND Tumor microenvironment (TME) characteristics including tumor stroma ratio (TSR), tumor budding (TB), and tumor-infiltrating lymphocytes (TILs) were examined in resected gastric cancer. These TME features have been shown to indicate metastatic potential in colon cancer, and intestinal-type gastric cancer (IGC) has pathological similarities with that malignancy. METHODS TSR, TB, and TILs were quantified in routine histological sections from 493 patients with IGC who underwent radical resection at 2 university hospitals in China from 2010 to 2016. TME variables were dichotomized as follows: TSR (50%), TILs (median), TB per international guidelines (4 buds/0.785mm2), and platelet-lymphocyte ratio (PLR) per survival ROC. Association of TME features with patient clinicopathological characteristics, time-to-recurrence (TTR), and cancer-specific-survival (CSS) were examined using univariate and multivariate analysis, including a relative contribution analysis by Cox regression. RESULTS Patients whose tumors showed high TSR or high TB or low TILs were each significantly associated with increased T and N stage, higher histological grade, and poorer TTR and CSS at 5 years. Only TSR and N stage were independently associated with TTR and CSS after adjustment for covariates. PLR was only independently associated with TTR after adjustment for covariates. Among the variables examined, only TSR was significantly associated with both TTR (HR 1.72, 95% CI, 1.14-2.60, P = .01) and CSS (HR 1.62, 95% CI, 1.05-2.51, P = .03) multivariately. Relative contribution to TTR revealed that the top 3 contributors were N stage (45.1%), TSR (22.5%), and PLR (12.9%), while the top 3 contributors to CSS were N stage (59.9%), TSR (14.7%), and PLR (10.9%). CONCLUSIONS Among the examined TME features, TSR was the most robust for prognostication and was significantly associated with both TTR and CSS. Furthermore, the relative contribution of TSR to patient TTR and CSS was second only to nodal status.

A Review of Recent Advances in Computer-Aided Detection Methods Using Hyperspectral Imaging Engineering to Detect Skin Cancer. Cancers (Basel) 2023; 15:5634. [PMID: 38067338 PMCID: PMC10705122 DOI: 10.3390/cancers15235634] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Revised: 11/20/2023] [Accepted: 11/24/2023] [Indexed: 08/15/2024] Open
Abstract
Skin cancer, a malignant neoplasm originating from skin cell types including keratinocytes, melanocytes, and sweat glands, comprises three primary forms: basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and malignant melanoma (MM). BCC and SCC, while constituting the most prevalent categories of skin cancer, are generally considered less aggressive compared to MM. Notably, MM possesses a greater capacity for invasiveness, enabling infiltration into adjacent tissues and dissemination via both the circulatory and lymphatic systems. Risk factors associated with skin cancer encompass ultraviolet (UV) radiation exposure, fair skin complexion, a history of sunburn incidents, genetic predisposition, immunosuppressive conditions, and exposure to environmental carcinogens. Early detection of skin cancer is of paramount importance to optimize treatment outcomes and preclude the progression of disease, either locally or to distant sites. In pursuit of this objective, numerous computer-aided diagnosis (CAD) systems have been developed. Hyperspectral imaging (HSI), distinguished by its capacity to capture information spanning the electromagnetic spectrum, surpasses conventional RGB imaging, which relies solely on three color channels. Consequently, this study offers a comprehensive exploration of recent CAD investigations pertaining to skin cancer detection and diagnosis utilizing HSI, emphasizing diagnostic performance parameters such as sensitivity and specificity.

Abstract
Rationally designed and engineered bacteria represent an emerging unique approach for cancer treatment. Here, we engineer a short-lived bacterium, mp105, that is effective against diverse cancer types and safe for intravenous administration. We reveal that mp105 combats cancer by direct oncolysis, depletion of tumor-associated macrophages, and elicitation of CD4+ T cell immunity. We further engineer a glucose-sensing bacterium named m6001 that selectively colonizes solid tumors. When intratumorally injected, m6001 clears tumors more efficiently than mp105 due to its post-delivery replication in tumors and potent oncolytic capacity. Finally, we combine intravenous injection of mp105 and intratumoral injection of m6001, forming a double team against cancer. The double team enhances cancer therapy compared with single treatment for subjects carrying both intratumorally injectable and uninjectable tumors. The two anticancer bacteria and their combination are applicable to different scenarios, turning bacterial therapy for cancer into a feasible solution.

Abstract
The prognosis of patients with advanced pancreatic cancer is poor despite the recent introduction of immune checkpoint inhibitors. Therefore, the development of new therapeutic approaches is urgently required. In the present phase I/II study, we have evaluated the safety, the efficacy and the prognostic factors of Wilms' tumor 1 (WT1) and/or mucin 1 (MUC1) peptide-loaded dendritic cell (DC) vaccination in combination with a chemotherapy employing gemcitabine plus nab-paclitaxel or a combination chemotherapy regimen consisting of oxaliplatin, irinotecan, fluorouracil and leucovorin (FOLFIRINOX) in patients with advanced or relapsed pancreatic ductal adenocarcinoma (PDAC). Forty-eight eligible patients were enrolled and received the vaccinations approximately every 2-4 weeks at least seven times. No severe adverse events related to the vaccinations were observed. Median progression free survival and overall survival were 8.1 months and 15.1 months, respectively. DC vaccinations augmented tumor specific immunity which might be related to clinical outcome. The multivariate analyses demonstrated that WT1 or MUC1-specific interferonɤ enzyme-linked immunospot number prior to DC vaccination was an independent prognostic factor related to overall survival. These results indicate that DC-based immunotherapy combined with a conventional chemotherapy is safe and has clinical benefits for patients in advanced stage of PDAC. The precise evaluation of the baseline antitumor specific immunity is critical to predict clinical outcome.

Abstract
OBJECTIVES Some studies have identified tumour-infiltrating lymphocytes (TILs) in H&E-stained sections of gastric cancer, but the prognostic and clinicopathological significance of this remains unclear. The objective of this study is to evaluate the associations between H&E-based TIL density and prognosis and clinicopathological characteristics of patients with gastric cancer. DESIGN Systematic review and meta-analysis. DATA SOURCES Cochrane Library, PubMed and Embase databases were searched through 25 February 2020. ELIGIBILITY CRITERIA Studies evaluating the correlations between TILs assessed by H&E-stained sections and prognosis and clinicopathological characteristics of gastric cancer were included. DATA EXTRACTION AND SYNTHESIS Relevant data were extracted and risks of bias were assessed independently by two reviewers. HR and relative risk (RR) with 95% CI were pooled by random-effect models to estimate the associations between TIL density and overall survival (OS) and clinicopathological characteristics, respectively. RESULTS We enrolled nine studies including 2835 cases for the present meta-analysis. High TILs were associated with superior OS (HR=0.68, 95% CI 0.52 to 0.87, p=0.003) compared with low TILs. High TILs were significantly associated with lower depth of invasion (T3-T4 vs T1-T2) (RR=0.58, 95% CI 0.50 to 0.66, p<0.001), less lymph node involvement (presence vs absence) (RR=0.68, 95% CI 0.56 to 0.81, p<0.001) and earlier TNM (tumour, node, metastasis) stage (III-IV vs I-II) (RR=0.68, 95% CI 0.55 to 0.83, p<0.001). TIL density was not associated with age, gender, Lauren classification or histological grade. The methodology for evaluating TIL and its cut-off value varied across different studies, which might affect the results of our meta-analysis. CONCLUSIONS Our meta-analysis suggests that H&E-based TIL density is a reliable biomarker to predict the clinical outcomes of patients with gastric cancer. Multicentre, prospective studies are needed to further confirm our findings. PROSPERO REGISTRATION NUMBER CRD42020169877.

Abstract
Arsenic trioxide (ATO), an FDA-approved drug for acute promyelocytic leukemia, also has great potential for treatment of solid tumors. Drug delivery powered by recent advances in nanotechnology has boosted the efficacy of many drugs, which is enlightening for applications of ATO in treating solid tumors. Herein, we reported arsenite-loaded multifunctional nanoparticles that are capable of pH-responsive ATO release for treating hepatocellular carcinoma (HCC) and real-time monitoring via magnetic resonance imaging. We fabricated these nanoparticles (designated as magnetic large-pore mesoporous silica nanoparticle (M-LPMSN)-NiAsO x ) by loading nanoparticulate ATO prodrugs (NiAsO x ) into the pores of large-pore mesoporous silica nanoparticles (LPMSNs) that contain magnetic iron oxide nanoparticles in the center. The surface of these nanodrugs was modified with a targeting ligand folic acid (FA) to further enhance the drug efficacy. Releasing profiles manifest the responsive discharging of arsenite in acidic environment. In vitro experiments with SMMC-7721 cells reveal that M-LPMSN-NiAsO x -FA nanodrugs have significantly higher cytotoxicity than traditional free ATO and induce more cell apoptosis. In vivo experiments with mice bearing H22 tumors further confirm the superior antitumor efficacy of M-LPMSN-NiAsO x -FA over traditional free ATO and demonstrate the outstanding imaging ability of M-LPMSN-NiAsO x -FA for real-time tumor monitoring. These targeted arsenite-loaded magnetic mesoporous silica nanoparticles integrating imaging and therapy hold great promise for treatment of HCC, indicating the auspicious potential of LPMSN-based nanoplatforms.

Abstract
Background In patients with gastric cancer, the prognostic value of tumor-infiltrating lymphocytes (TILs) is still controversial. A meta-analysis was performed to evaluate the prognostic value of TILs in gastric cancer. Materials and methods We identify studies from PubMed, Embase and the Cochrane Library to assess the prognostic effect of TILs in patients with gastric cancer. Fixed-effects models or random-effects models were used estimate the pooled hazard ratios (HRs) for overall survival (OS) and disease-free survival (DFS), which depend on the heterogeneity. Results A total of 31 observational studies including 4,185 patients were enrolled. For TILs subsets, the amount of CD8+, FOXP3+, CD3+, CD57+, CD20+, CD45RO+, Granzyme B+ and T-bet+ lymphocytes was significantly associated with improved survival (P < 0.05); moreover, the amount of CD3+ TILs in intra-tumoral compartment (IT) was the most significant prognostic marker (pooled HR = 0.52; 95% CI = 0.43–0.63; P < 0.001). However, CD4+ TILs was not statistically associated with patients’ survival. FOXP3+ TILs showed bidirectional prognostic roles which had positive effect in IT (pooled HR = 1.57; 95% CI = 1.04–2.37; P = 0.033) and negative effect in extra-tumoral compartment (ET) (pooled HR = 0.76; 95% CI = 0.60–0.96; P = 0.022). Conclusions This meta-analysis suggests that some TIL subsets could serve as prognostic biomarkers in gastric cancer. High-quality randomized controlled trials are needed to decide if these TILs could serve as targets for immunotherapy in gastric cancer.

Abstract
PURPOSE To report the patient characteristics and treatment outcomes in 12 cases of orbital lymphangioma. METHODS In this study, orbital lymphangioma was diagnosed based on clinical, radiologic (computed tomography, magnetic resonance imaging), and histologic findings when possible. Patients whose vision was not compromised by orbital lymphangioma, or that did not have increased intraocular pressure (IOP), received oral corticosteroids. Orbital lymphangioma that affected vision or increased IOP was treated by surgery, which included aspiration of blood or partial resection with or without injection of a sclerosant. RESULTS Four patients without compromised vision responded well to oral corticosteroids. Eight patients with compromised vision underwent some form of surgery. Bleeding recurred in three patients after aspiration of blood and in two after partial resection and intralesional injection of a sclerosant. Overall, five patients were treated successfully by aspiration of blood, intralesional injection of a sclerosant, and application of continuous negative pressure by appropriate drainage. Partial resection was successful in two patients with organized hematoma. CONCLUSIONS Orbital lymphangioma that does not compromise vision can be treated medically using oral corticosteroids. Patients with threatened vision or elevated IOP due to acute hemorrhage should be treated by aspiration of blood, intralesional injection of a sclerosant, and application of continuous negative pressure. Partial resection may be effective only in patients with organized hematoma.

Abstract
BACKGROUND The purpose of this study was to systematically review clinically translatable immunotherapeutic agents that are delivered regionally for solid malignancies. DATA SOURCES PubMed and ClinicalTrials.gov were searched for published and registered clinical trials, respectively. The search yielded 334 relevant publications, of which 116 articles were included for review after exclusion criteria were applied. CONCLUSIONS There has been an increase in the regional administration of cell-based and viral vector-based clinical trials over the last 5 years. Surgical interventions have been developed for intrapleural, intracranial, intraperitoneal, and intratumoral routes of access to enhance the local delivery of these therapies. Multimodality therapies that combine regional immunotherapy with other local and systemic therapies are demonstrating continued growth as the field of immunotherapy continues to expand.

Abstract
This study outlines a drug delivery mechanism that utilizes two independent vehicles, allowing for delivery of chemically and physically distinct agents. The mechanism was utilized to deliver a new anti-cancer combination therapy consisting of piperlongumine (PL) and TRAIL to treat PC3 prostate cancer and HCT116 colon cancer cells. PL, a small-molecule hydrophobic drug, was encapsulated in poly (lactic-co-glycolic acid) (PLGA) nanoparticles. TRAIL was chemically conjugated to the surface of liposomes. PL was first administered to sensitize cancer cells to the effects of TRAIL. PC3 and HCT116 cells had lower survival rates in vitro after receiving the dual nanoparticle therapy compared to each agent individually. In vivo testing involved a subcutaneous mouse xenograft model using NOD-SCID gamma mice and HCT116 cells. Two treatment cycles were administered over 48 hours. Higher apoptotic rates were observed for HCT116 tumor cells that received the dual nanoparticle therapy compared to individual stages of the nanoparticle therapy alone.

Abstract
Malignant transformation results in increased levels of reactive oxygen species (ROS). Adaption to this toxic stress allows cancer cells to proliferate. Recently, piperlongumine (PL), a natural alkaloid, was identified to exhibit novel anticancer effects by targeting ROS signaling. PL induces apoptosis specifically in cancer cells by downregulating several anti-apoptotic proteins. Notably, the same anti-apoptotic proteins were previously found to reduce tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)-induced apoptosis in cancer cells. Therefore, we reasoned that PL would synergize with TRAIL to stimulate potent apoptosis in cancer cells. We demonstrate for the first time that PL and TRAIL exhibit a synergistic anti-cancer effect in cancer cell lines of various origins. PL resulted in the upregulation of TRAIL receptor DR5, which potentiated TRAIL-induced apoptosis in cancer cells. Furthermore, such upregulation was found to be dependent on ROS and the activation of JNK and p38 kinases. Treatment with combined PL and TRAIL demonstrated significant anti-proliferative effects in a triple-negative breast cancer MDA-MB-231 xenograft model. This work provides a novel therapeutic approach for inducing cancer cell death. Combination of PL and TRAIL may suggest a novel paradigm for treatment of primary and metastatic tumors.

Abstract
Growth of a tumor on the left flank was suppressed by direct injection of immature DCs (iDCs) into the irradiated tumor on the right thigh (IR/DC). This antitumor immune effect of IR/DC was enhanced by pretreatment with CTX (CTX+IR/DC) and this effect was related with increased number of tumor-specific IFN-γ secreting T cells and decreased ratio of CD4(+)CD25(+)/CD4(+) T cells. The treatment with CTX+IR/DC increased or decreased the levels of IL-2 or IL-10, respectively. These results demonstrated that antitumor effect of IR/DC could be augmented by pretreatment with low-dose CTX, suggesting a new antitumor therapeutic modality of chemoradioimmunotherapy.

Chitin and chitosan as multipurpose natural polymers for groundwater arsenic removal and AS2O3 delivery in tumor therapy. Mar Drugs 2010; 8:1518-25.

Abstract
Chitin and chitosan are natural polysaccharide polymers. These polymers have been used in several agricultural, food protection and nutraceutical applications. Moreover, chitin and chitosan have been also used in biomedical and biotechnological applications as drug delivery systems or in pharmaceutical formulations. So far, there are only few studies dealing with arsenic (As) removal from groundwater using chitin or chitosan and no evidence of the use of these natural polymers for arsenic trioxide (As2O3) delivery in tumor therapy. Here we suggest that chitin and/or chitosan might have the right properties to be employed as efficient polymers for such applications. Besides, nanotechnology offers suitable tools for the fabrication of novel nanostructured materials of natural origin. Since different nanostructured materials have already been employed successfully in various multidisciplinary fields, we expect that the integration of nanotechnology and natural polymer chemistry will further lead to innovative applications for environment and medicine.

Abstract
OBJECTIVE To describe our experience with sclerosing treatment of lymphangiomas in the head and neck region by intralesional injections of OK-432. STUDY DESIGN Case series. METHODS Patients with the diagnosis of a macrocystic-type cervical lymphangioma were treated by one to three intralesional injections of OK-432 (0.01 mg of OK-432/1 mL of lymphangioma fluid, up to a maximum of 0.2 mg in the first injection and 0.3 mg in the second or third injections). All injections were performed under ultrasound guidance. Children were injected under sedation. RESULTS Eleven patients were treated with injections of OK-432: 7 children and 4 adults. They were followed up for a period of 5 to 68 (mean 30) months. Eight (73%) patients had complete or subcomplete resolution of the lymphangioma after one or two injections. In three (27%) cases, no response was obtained (2 cases) or the lymphangioma recurred (1 case) after two to three injections. In two cases, surgical excision was performed. There was no evidence of fibrosis around the cysts. There were no complications to OK-432 injections. CONCLUSION Intralesional injection of OK-432 is an effective treatment modality for macrocystic-type lymphangiomas in the head and neck region. It has no complications, and surgical excision in case of failure is not compromised by fibrosis. Sclerosing of macrocystic-type lymphangiomas with OK-432 should therefore be considered before surgical excision.

Abstract
BACKGROUND Surgical excision of orbital lymphangiomas is difficult, and almost always incomplete due to the diffusely infiltrative pattern of these tumors. The present report describes the successful use of intralesional OK-432 administration to treat two patients with intractable hemorrhagic proptosis due to orbital lymphangiomas. METHODS A 3-year-old girl (case 1) presented with aggressive proptosis and ptosis, and a 1-year-old boy (case 2) presented with massive proptosis and exposure keratopathy, associated with recurrent intracystic bleeding of an orbital lymphangioma. In case 1, 0.02 mg OK-432 was intracystically injected in a volume of 2 ml of physiologic saline. Due to a lack of therapeutic response, a second injection of 0.05 mg OK-432 in 1 ml was administered. In case 2, a single dose of 0.05 mg OK-432 in 1 ml was administered. RESULTS In both cases, intracystic administration of 0.05 mg of OK-432 in a 1-ml volume resulted in a successful outcome. The adverse effects were minor (mild transient fever and lid swelling), and rebleeding and intraocular pressure elevation did not occur. Proptosis and eyelid swelling gradually improved over 1 month, and completely resolved within 3 months of treatment. CONCLUSIONS Intralesional administration of 0.05 mg/ml OK-432 (delivered in 1 ml) resulted in the successful treatment of two cases of orbital lymphangioma. Although this drug concentration is higher than in previous reports, there were no major adverse effects.

Abstract
BACKGROUND There is evidence that cancer is immunogenic under certain situations. IL-2 is described to stimulate an effective antitumor immune response in vitro and in vivo. The ability of cancer patients to undergo surgical resection is still the most important prognostic factor for many solid tumors, including gastric adenocarcinoma. The host immune system may be further compromised by surgical procedures leading to a generalized state of immunodepression in the post-operative period. The aim of this randomized case-control study is to evaluate the effects of pre-operative low-dose IL-2 treatment on patients with gastric adenocarcinoma who undergo surgery. METHODS Sixty-eight patients with gastric adenocarcinoma were enrolled in the study and randomized in two groups: 36 patients were pre-treated with IL-2 and 32 underwent surgery without any treatment. Total peripheral WBC, neutrophils, CD3(+) T, CD4(+) T, CD8(+) T and NK cells were obtained before and after surgery, at different times. Peritumoral infiltration was analyzed on all surgical specimens. Overall survival and relapse-free survival were studied with a median follow-up of 51 months. RESULTS Low-dose IL-2 treatment resulted in an increase peritumoral lymphocytic and eosinophilic infiltrations and in a minor decrease in CD3(+) T and CD4(+) T cells after surgery (P < 0.05). A stepwise multivariate analysis revealed that overall survival and relapse-free survival were affected only by stage of tumor and age of patients. CONCLUSIONS According to our data low-doses of IL-2 administered pre-operatively to patients with gastric cancer activate peripheral and peri-tumoral lymphocytes but did not affect prognosis.

Abstract
Arsenic trioxide (As2O3) is a potent antitumor agent used to treat acute promyelocytic leukemia (APL) and, more recently, solid tumors. However, the dose of As2O3 required to suppress human xenographs in mice is markedly higher than that used to treat APL in humans. Paradoxically, low doses of As2O3 stimulate angiogenesis, which might be expected to promote tumor growth. Clearly, appropriate dosages of As2O3 are required to treat human patients to avoid toxicity and undesirable side effects. In the present study, we investigated As2O3 with respect to its toxicity and effects on tumor growth, angiogenesis and cell apoptosis using H22 hepatocellular carcinoma (HCC) cells in a mouse model of HCC. As2O3 inhibited tumor growth and angiogenesis, and enhanced tumor cell apoptosis at doses greater than 1 mg/kg, but mice lost weight and failed to thrive at doses of 4 mg/kg and greater. In contrast, low doses (<1 mg/kg) of As2O3 promoted tumor growth, upregulated the expression of vascular endothelial growth factor and tumor angiogenesis, and had no effect on tumor cell apoptosis. In vitro studies demonstrated that As2O3 inhibited the proliferation of H22 tumor cells and bovine aortic endothelial cells, and induced their apoptosis in a dose- and time-dependent fashion, suggesting that the mechanism of As2O3-mediated inhibition of tumor growth is due to direct effects of the drug on both tumor cells and endothelia. In summary, different doses of As2O3 have opposing effects on tumor growth and angiogenesis. The results demonstrate that As2O3 has a narrow window of therapeutic opportunity with respect to dosage, and that low doses of the drug as used in metronomic therapy should be used with extreme caution.

Abstract
Arsenic trioxide (As(2)O(3)), a valuable anticancer drug for the treatment of acute promyelocytic leukemia, may also have therapeutic potential for the treatment of solid tumors. However, its therapeutic efficacy against solid tumors is lacking even at high dosages. Other therapeutic strategies are required to enhance the efficacy of As(2)O(3) against solid tumors such as hepatocellular carcinoma (HCC), which is refractory to chemotherapy. B7H3, a new member of the B7 family, has been shown to induce antitumor immunity. Intratumoral injection of B7H3 plasmids eradicates small EL-4 lymphomas, but monotherapy is ineffective against large tumors. Here we investigated whether As(2)O(3) would synergize with B7H3 immunotherapy to combat HCC. Large subcutaneous H22 HCCs (0.7-0.8 cm in diameter) established in BALB/c mice were rapidly and completely eradicated when intratumoral administration of As(2)O(3) was preceded by in situ gene transfer of B7H3. In contrast, neither As(2)O(3) nor B7H3 monotherapy was effective. The antitumor activity of As(2)O(3) was attributed to increased tumor-cell apoptosis, perhaps as a result of direct cytotoxicity as well as decreased tumor angiogenesis. Combination therapy generated potent systemic antitumor immunity mediated by CD8(+) and NK cells that was effective in combating a systemic challenge of 1 x 10(7) parental H22 cells. It led to the simultaneous and complete regression of multiple distant tumor nodules, concomitant with increased levels of serum IFN-gamma and cytotoxic T lymphocyte (CTL) activity. In conclusion, combining B7H3-mediated immunotherapy with As(2)O(3) warrants investigation as a therapeutic strategy to combat HCC, and other malignancies.

Abstract
PURPOSE Human scirrhous gastric carcinoma develops peritoneal dissemination with high frequency, and the prognosis of patients with peritoneal metastasis is poor. There have been few reports of an immunogene therapy for peritoneal dissemination. Intercellular adhesion molecule (ICAM)-2 is a second ligand of leukocyte function-associated antigen-1, which functions as a costimulatory molecule for effector cells. In the present study, we examined whether ICAM-2 transfection using adenovirus vector is effective gene therapy for peritoneal metastasis of gastric cancer. EXPERIMENTAL DESIGN We constructed an adenovirus vector, AdICAM-2, that encodes the full-length human ICAM-2 gene under control of the cytomegalovirus promoter. This vector expresses high levels of ICAM-2 on the human gastric cancer cell line OCUM-2MD3, which has high peritoneal metastatic ability in nude mice. We investigated the antitumor effects of gene transfer of ICAM-2 using the adenovirus vector AdICAM-2 in vitro and in vivo. RESULTS ICAM-2 expressed on OCUM-2MD3 cells by AdICAM-2 demonstrated significantly high adhesiveness to and cytotoxicity against peripheral blood mononuclear cells in vitro compared with the control adenovirus vector AdlacZ. Intratumoral injection of AdICAM-2 significantly inhibited the growth of s.c. tumor. Mice with peritoneal metastasis survived for a significantly longer time after AdICAM-2 injection, compared with injection of AdlacZ. Histopathological findings revealed that many natural killer cells infiltrated the peritoneal metastatic lesions after AdICAM-2 injection. CONCLUSIONS These findings suggest that transduction of ICAM-2 into cancer cells enhances the adhesion and activation of natural killer cells, resulting in a reduction of peritoneal metastasis. ICAM-2 transfection using adenovirus vector might be an effective form of gene therapy for peritoneal metastasis of gastric cancer.

Abstract
In total, 16 patients with cytologically proven malignant effusion from colorectal cancer were treated by locoregional administration of the streptococcal preparation OK-432 alone or OK-432 plus the T-cell growth factor interleukin (IL)-2, and the action mechanism of the treatment was studied. A positive clinical response, showing a cytologic disappearance of cancer cells and decrease of effusion, was observed in nine of 11 (82%) patients treated with OK-432 alone and in all five patients treated with OK-432 plus IL-2. Flow cytometric analysis revealed that OK-432 plus IL-2 locally induced acute inflammation-like responses, including serial cellular infiltrations of granulocyte migration within a matter of hours, and activation of macrophages and T lymphocyte involvement within the following days, and that a predominant expansion of CD3+CD4+ lymphocytes (CD: cluster of differentiation) was induced by in vitro stimulation with IL-2 of locoregional cells after the OK-432 administration (OK/IL-2AK cells). The OK/IL-2AK cells produced tumour necrosis factor-α and interferon-γ, but these cells did not produce IL-4 and IL-6. The OK/IL-2AK cells expressed potent killing activity against autologous tumour cells. This activity was abrogated by treatment of the lymphocytes with anti-CD3, -CD4, -TCRαβ antibody, and by the treatment of target cells with anti-human leukocyte antigen (HLA)-DR antibody. The OK/IL-2AK cells expressed Fas-L gene, and flow cytometric analysis demonstrated HLA-DR expression in approximately 75% of CEA+ or cytokeratin+ effusion cells. TCRVβ gene analysis of the OK/IL-2AK cells showed an oligoclonal usage of TCRβ20, which was also involved in the cytotoxic mechanism of the OK/IL-2AK cells. Single-strand conformational polymorphism analysis demonstrated the clonotypes for the TCRVβ20 gene, and the CDR3s of the gene were sequenced. The clonotypic PCR using the TCRVβ20-CDR3 sequences could detect the CDR3-identical TCRs in effusion lymphocytes from the other patients. Taken together, it is suggested that locoregional administration of OK-432 plus IL-2 is highly effective for the management of malignant effusion from colorectal cancer. OK-432 plus IL-2 induces autologous tumour-reactive CD4+ Th1 killer lymphocytes, which recognise tumour antigen(s) presented with HLA class II molecules on effusion tumour cells by means of preferential usage of TCRVβ20. The clonotypic PCR using the TCRVβ20-CDR3 sequences may be informative for treating malignant effusion from colorectal cancer using OK-432 plus IL-2.

Abstract
A case of advanced gingival cancer is described. The cancer invaded into the mandible and skin of the cheek and was associated with cervical lymph node metastases, mediastinal lymph node metastases, and bilateral multiple pulmonary metastases. The patient received neoadjuvant chemoradiotherapy and local immunotherapy, followed by curative surgery for the primary and neck lesions. Histopathological examination of the primary cancer and the upper and middle cervical nodes (n = 7) indicated a diagnosis of squamous cell carcinoma. Sections of the lower cervical nodes (n = 5) revealed well-differentiated thyroid carcinoma, suggesting that the mediastinal and pulmonary lesions were of thyroid origin. After total thyroidectomy and mediastinal dissection followed by treatment with radioiodine, the multiple pulmonary nodules disappeared. There has been no evidence of recurrent tumour for 5 years.

Abstract
OBJECTIVES Cytokines produced by tumor cells and tumor-infiltrating lymphocytes (TIL) appear to regulate tumor cell growth and the cytotoxic activity of TIL. The objectives of the present study were to investigate cytokine generation patterns in tumor cells and TIL and to examine the influence of cancer therapy on this cytokine production and the cytotoxic activity of TIL. METHODS We determined the levels of cytokines produced by tumor cells and TIL in vitro and measured the cytotoxic activity of TIL against Daudi cells in patients with oral squamous cell carcinoma (OSC) before and 1 week after the start of concomitant chemo-radio-immunotherapy. RESULTS Before the therapy, OSC cells generated higher levels of granulocyte-macrophage colony-stimulating factor, tumor necrosis factor-alpha (TNF-alpha) and transforming growth factor-beta (TGF-beta) than did oral keratinocytes isolated from the noninflamed gingivae of healthy individuals, but both kinds of cells generated similar levels of interleukin (IL)-1beta and IL-6. Compared with peripheral blood mononuclear cells (PBMC) of the patients, TIL produced higher levels of IL-1beta, IL-6, IL-10, TNF-alpha and TGF-beta, whereas their production of IL-12 and interferon-gamma (IFN-gamma) was only slightly higher than that in PBMC. After 1 week of therapy, the cytokine production by OSC cells had largely decreased, while the production of TNF-alpha, IFN-gamma, TGF-beta and IL-12 by TIL had increased greatly, although other cytokine levels were almost constant during the investigations. The cytotoxic activity of TIL was higher than that of PBMC before the therapy, and this activity was strongly increased by 1 week of therapy. CONCLUSIONS These results suggest that the cytokine productivities of TIL and tumor cells differ from those of PBMC and normal keratinocytes, respectively, and that chemo-radio-immunotherapy modulates in situ cytokine generation, which is advantageous for inhibition of tumor cell growth and activation of TIL.

Abstract
The recent literature documents the growing interest in local intratumoral chemotherapy as well as systemic preoperative chemotherapy with evidence for improved outcomes using these therapeutic modalities. Nevertheless, with few exceptions, the conventional wisdom and standard of care for clinical and surgical oncology remains surgery followed by radiation and/or systemic chemotherapy, as deemed appropriate based on clinical findings. This, in spite of the fact that the toxicity of conventional systemic chemotherapy and immunotherapy affords limited effectiveness and frequently compromises the quality of life for patients. Indeed, with systemic chemotherapy, the oncologist (and the patient) often walks a fine line between attempting tumour remission with prolonged survival and damaging the patient's vital functions to the point of death. In this context, it has probably been obvious for more than 100 years, due in part to the pioneering work of Ehrlich (1878), that targeted or localized drug delivery should be a major goal of chemotherapy. However, there is still only limited clinical use of nonsystemic intratumoral chemotherapy for even those high mortality cancers which are characterized by well defined primary lesions i.e. breast, colorectal, lung, prostate, and skin. There has been a proliferation of intratumoral chemotherapy and immunotherapy research during the past two to three years. It is therefore the objective of this review to focus much more attention upon intratumoral therapeutic concepts which could limit adverse systemic events and which might combine clinically feasible methods for localized preoperative chemotherapy and/or immunotherapy with surgery. Since our review of intratumoral chemoimmunotherapy almost 20 years ago (McLaughlin & Goldberg 1983), there have been few comprehensive reviews of this field; only one of broad scope (Brincker 1993), three devoted specifically to gliomas (Tomita 1991; Walter et al. 1995; Haroun & Brem 2000), one on hepatomas (Venook 2000), one concerning veterinary applications (Theon 1998), and one older review of dermatological applications (Goette 1981). However, none have shed light on practical opportunities for combining intratumoral therapy with subsequent surgical resection. Given the state-of-the-art in clinical and surgical oncology, and the advances that have been made in intratumoral drug delivery, minimally invasive tumour access i.e. fine needle biopsy, new drugs and drug delivery systems, and preoperative chemotherapy, it is timely to present a review of studies which may suggest future opportunities for safer, more effective, and clinically practical non-systemic therapy.

Abstract
BACKGROUND OK-432 is known to increase the host antitumor response. We previously reported that systemic administration of OK-432 (OK-Lipo) specifically induced hepatic lymphocytes in mice. Here we aimed to investigate the antitumor effect of OK-Lipo on hepatocellular carcinomas (HCC) in experimental rats. METHODS Diethylnitrosamine was administered for 12 weeks to all rats (n = 36). Rats were divided into three groups of 12 rats each. One group was injected with OK-Lipo from week 5 (OK-5w group) and another from week 9 (OK-9w group). A control group was injected with saline from week 5 (Non-OK group). At week 13, five rats from each group were used for histological analysis and immunofluorescence assays (surface phenotypic and intracellular cytokine analysis of the mononuclear cells in the liver, spleen and peripheral blood). The remaining rats were observed for the remainder of their survival period. RESULTS The mean survival times of Non-OK, OK-5w, and OK-9w groups differed significantly (98.0 +/- 5.3 days, 116.0 +/- 5.8 days, and 106.0 +/- 5.4 days, respectively, P < 0.01). Histological examination revealed many apoptotic tumor cells, infiltration of lymphocytes and macrophages in the OK-5w group. The two-color immunofluorescence assay showed that the proportion of natural killer (NK) cells and IFN-gamma-producing cells in the liver were significantly higher in the OK-5w group. CONCLUSIONS These findings showed that systemic administration of OK-Lipo contributed to prolonging the survival of rats with HCC. OK-Lipo induced NK cells and IFN-gamma-producing cells specifically in the liver and these cells seemed to reduce hepatocarcinogenesis and tumor growth.
