Abstract
We report a rare case of spontaneous regression of diffuse intrahepatic recurrence with portal vein tumor thrombus (PVTT) after resection of hepatocellular carcinoma (HCC). A 68-year-old man with hepatitis C virus-related liver cirrhosis presented with a 40 mm tumor in the right anterior segment of the liver. The tumor was diagnosed as HCC by typical imaging findings and elevated serum alpha-fetoprotein (AFP) (716 ng/ml) and protein induced by vitamin K absence II (PIVKA II) (8,100 ng/ml). A right anterior sectionectomy of the liver was performed. Microscopically, the tumor was moderately differentiated HCC. Four months after resection, a computed tomography (CT) scan showed diffuse intrahepatic recurrence with PVTT. Serum AFP was 12,319 ng/ml and PIVKA II was 168,000 ng/ml. The patient did not receive any further treatment for HCC including herbal medicine, and stopped smoking. Two years and 5 months later, no lesion was detected on a CT scan when serum AFP was 1.9 ng/ml. Ischemia due to main portal vein occlusion and rapid tumor growth might have induced tumor regression in the present case. Moreover, abstention from smoking might have improved his immunological function.

Abstract
BACKGROUND/AIMS Locoregional chemotherapy continues to be the mainstay for the treatment of unresectable hepatocellular carcinoma (HCC). One of the principal obstacles implicated in its unsuccessful therapy is multidrug resistance (MDR). Former studies have identified the multidrug-resistant nature and possible mechanisms of hepatoma cells both in vitro and in vivo. This work aimed to develop an effective strategy for the treatment of HCC with MDR. METHODS The treatment was exploited to inhibit the MDR cells by co-administration of the recombinant mutant human tumour necrosis factor-alpha (rmhTNF-alpha), a sublethal dose of chemicals [adriamycin (ADM), mitomycin and 5-FU] and hydroxyapatite nanoparticles (nHAPs). Real-time quantitative reverse transcriptase-polymerase chain reaction and electrochemiluminescence Western blot were used to detect the expression of several related genes. RESULTS The chemicals acted synergistically with rmhTNF-alpha and nHAP in suppressing the growth of hepatoma cells and inducing apoptosis of the cells, with the MDR phenotype reversed, as measured by intracellular ADM retention. Analysis of mRNA and protein revealed that rmhTNF-alpha inhibited the gene expression of XIAP, survivin, Ki67, PCNA, MDR1 and BCRP to some extent. Moreover, the inhibitory effects mentioned above could be as good or better than when nHAP is incorporated into the regimens. CONCLUSIONS rmhTNF-alpha was not only able to restore the chemotherapeutic sensitivity to HepG2/ADM, its xenograft model and clinical samples but also further inhibited the growth of these tumours by a combination of nHAP. These results strongly suggested that chemicals in combination with rmhTNF-alpha and nHAP may be beneficial for the local treatment of advanced HCC.

Abstract
The efficacy and safety of the recombinant mutant human tumor necrosis factor (rmhTNF) combined with chemotherapy vs chemotherapy alone in the treatment of patients with small cell lung cancer (SCLC) were evaluated in this study. The selected 37 patients with SCLC were divided into experimental group (n =18) and control group (n = 19). Both groups were subjected to EP regimen. While in the experimental group, a regimen of 4 x 10(6) U/m2 rmhTNF intramuscular injection was given once a day from the 1st to 7th day and 11th to 17th day on the chemotherapy cycle. Twenty-one days were as a chemotherapy cycle and all patients received treatment with 2 cycles. The response rate was 83.3% (15/18) in the experimental group and 63.2% (12/19) in the control group respectively (P < 0.05). The KPS score after treatment was 78.4 +/- 9.6 in the experimental group and 71.2 +/- 9.7 in the control group with the difference being significant (P < 0.05). No severe adverse effects occurred in the two groups. It was concluded that the curative effectiveness of the rmhTNF combined with chemotherapy in the treatment of SCLC was more satisfactory than chemotherapy alone. The former could obviously improve the quality of life of the patients with SCLC.

Abstract
The purpose was to examine interleukin (IL)-1 concentrations and intercellular adhesion molecule (ICAM)-1 expression in nicotine/arecoline-exposed oral KB CCL17 cultures. Enzyme-linked immunosorbent assay was used to quantify IL-1 concentrations in culture supernatants. A repeated-measures analysis of variance was used to identify differences among the groups. IL-1 beta concentrations increased by 2.6, 2.7 and 7.5 times those of the control in groups treated with 1 microM nicotine, arecoline or with both, respectively. IL-1 beta concentrations were more dramatically increased when the agents tested were at 100 microM concentration. Similar, although less dramatic, alterations in IL-1 alpha concentrations were observed. The fluorescence intensity of ICAM-1 (CD54) analysed by flow cytometry was also significantly increased in a dose-dependent manner when the cells were treated with nicotine and/or arecoline. Nicotine and arecoline therefore significantly increased IL-1 alpha and -1 beta secretions and the surface expression of ICAM-1 in KB CCL17 cells.

Abstract
Spontaneous tumor regression, which is observed clinically and histologically in some primary melanomas, occurs in the absence of any effective therapy. It is probably immunologically mediated, because regressing melanomas are infiltrated with larger numbers of activated T cells, primarily CD4+, than nonregressing melanomas. To investigate the hypothesis that spontaneous regression of melanomas is caused by T-cell cytokine production, cytokine mRNA expression in 20 primary melanomas was examined using a noncompetitive, quantitative reverse-transcriptase polymerase chain reaction method. DNA standards were used to generate known numbers of molecules in each sample. Results were standardized to the internal control, glyceraldehyde-3-phosphate dehydrogenase. mRNA for CD35, lymphotoxin (TNF-beta), and IL-2 were significantly elevated in the ten regressing melanomas compared to the ten nonregressing melanomas. IFN-gamma mRNA was also elevated in regressing melanomas but failed to reach statistical significance. The Th2 cytokines IL-10 and IL-13 did not show differences in the regressing melanomas compared to nonregressing melanomas; neither did the pro-inflammatory cytokines IL-1alpha, IL-1beta, IL-6, IL-8, and TNF-alpha, nor the growth factors, bFGF and TGF-beta or GM-CSF. This study shows an association between Th1 cytokines and spontaneously regressing melanomas. Although we have not shown that these cytokines cause regression, these findings support our hypothesis that activated CD4+ T cells may mediate melanoma regression by secretion of Th1 cytokines.

Abstract
BACKGROUND Natural cytotoxicity, mediated by natural killer (NK) cells and cell with lymphokine-activated killer (LAK) activity, is believed to play an important role in host anti-cancer mechanisms. METHODS The authors critically review recent publications on the role of natural cytotoxicity in patients with cancer. RESULTS In patients with cancer, several studies have noted variations in the numbers and activity of NK and cells with LAK activity in different body compartments. NK cell activity in the peripheral blood lymphocytes (PBLs) is higher than that found in lymph nodes and within tumors, and this appears to be due to the presence of suppressor factors. The natural cytotoxicity of PBLs in patients with different types of cancers varies. However, there appears to be a trend for natural cytotoxicity to be reduced in certain cancer patients, possibly related to tumor volume or dissemination. Anti-cancer treatments (e.g., surgery, hormonal modulation, radiotherapy and chemotherapy) can also result in suppression of natural cytotoxicity, although the long-term effect on response to treatment and development of metastases is at present unknown. CONCLUSIONS NK and LAK cells, through the use of immune biologic modifiers, have been demonstrated to have a therapeutic role in the treatment of human cancers. Further studies are required to determine the optimal dosages and combinations of chemotherapeutic agents, the timing of surgery, and the adjuvant use of immune biologic response modifiers. An increasing awareness and understanding of this field, may allow for the future development of anti-cancer therapies.

Abstract
A basal cell carcinoma (BCC) cell line (BCC-1/KMC) has recently been successfully established from a patient. The production of interleukin-1 alpha (IL-1 alpha), IL-1 beta, IL-6 and IL-8 was assessed in comparison with that of cultured normal keratinocytes. The mRNA expression of these cytokines was measured by a reverse transcriptase-polymerase chain reaction (RT-PCR) method and the protein production by an ELISA. The cultured BCC cells spontaneously secreted more IL-6 and IL-8 but less IL-1 than the keratinocytes after culture for 24 h at 37 degrees C. It is suggested that the increased expression of IL-6 and IL-8 may indicate the transformation of normal keratinocytes to locally aggressive BCC.

Abstract
In the search for cytokines whose antiproliferative action could be enhanced by combination with dipyridamole, 2,6-bis(diethanolamino)-4,8-dipiperidinopyrimido[5,4-d]pyrim idine, the combination of tumor necrosis factor-alpha (TNF-alpha) with this agent was evaluated in various human tumor cell lines. Inhibition of the proliferation of human melanoma cell lines MM-1CB and HMV-1 by TNF-alpha (1-10(2) U/ml) was enhanced in culture dishes by combination treatment with dipyridamole (0.1-10 microM). The enhancement effect was also detected in other tumor cell lines: T98 (glioma), SCC-1CB (squamous cell carcinoma), HAC-2 (ovarian clear-cell carcinoma), HLE (hepatoma), HEC-1 (endometrial adenocarcinoma) and HOC-21 (ovarian serous cystadenocarcinoma). The incorporation of [14C]amino acids and [3H]uridine into acid-insoluble cell materials in the combination-treated cells was not significantly different from that in cells treated with TNF-alpha or dipyridamole. However, the incorporation of [3H]thymidine was specifically inhibited in all cell lines examined after more than 12 h of the TNF-alpha and dipyridamole combination treatment, although neither agent alone inhibited this incorporation. On the other hand, the growth of tumors induced by the injection of MM-1CB and HMV-1 cells into nude mice was more markedly inhibited by the subcutaneous administration of TNF-alpha in combination with orally administered dipyridamole than by either agent alone. The results presented suggested that dipyridamole is beneficial in assuring the effectiveness of anti-cancer cytokine therapy.

Abstract
Cytokines have been tested in the treatment of different skin cancers during the last decade, and treatment schedules have been established or proposed for several malignant skin tumors. Preferentially, the interferons and interleukin-2 were found to be effective in treating skin cancers. Interferons alpha and beta have been approved for the treatment of human immunodeficiency virus (HIV)-associated Kaposi's sarcoma, cutaneous T cell lymphoma, and malignant melanoma in several countries. Interferon alpha was found to be most effective in cutaneous T cell lymphoma with 40%-60% overall responses. When combining interferon alpha with psoralens and ultraviolet A (PUVA) or with retinoids, even higher response rates up to 60%-90% were reported, and long-term remissions have been described. A considerable activity of interferon alpha was found in HIV-associated Kaposi's sarcoma with response rates of 30%-50%. The effectiveness of Kaposi's sarcoma's treatment was further improved by combining interferon alpha and zidovudine. Responses to interferon alpha in metastatic malignant melanoma are rather seldom (10%-15%), but a stabilization of the disease with prolonged survival was reported after interferon alpha treatment. Additionally, interleukin-2 was found to be active in metastatic melanoma, with overall response rates of about 20%, and both biological agents were found to have an additive efficacy in combination. Several combined regimens of interferon alpha, interleukin-2, and polychemotherapy have been described in metastatic melanoma, and overall response rates higher than 50% were found with these combined treatment modalities. Interferon alpha and beta were also intralesionally injected into basal cell carcinomas and other epithelial skin cancers, and complete responses were found in more than 80% of tumors treated. Local applications of interferons and interleukin-2 were likewise found to be effective in the treatment of cutaneous melanoma metastases and cutaneous manifestations of Kaposi's sarcoma. Cytokines and their combination with other treatment modalities has greatly enriched the treatment facilities in malignant skin tumors during recent years, and additional new cytokines will be introduced in skin cancer treatment in near future.

Abstract
Recombinant interleukin 2 (rIL-2), when given to patients with advanced malignant disease, induces a limited beneficial effect, with only 20-30% of patients with solid tumours responding. This present study has identified those patients with advanced colorectal cancer most likely to respond to rIL-2 therapy, by analysis of serum cytokine levels, prior to and during rIL-2 treatment, documented in responders and non-responders. Responders were found to have significantly lower pretreatment serum IL-6 and soluble IL-2 receptor levels (sIL-2R) than non-responders (P < 0.01 and P < 0.05 respectively). During rIL-2 infusion, responders developed high circulating levels of IL-6 and had low constant levels of prostaglandin E2 (PGE2). Non-responders failed to produce IL-6 and demonstrated elevated serum concentrations of PGE2, during infusions of rIL-2. Thus, an enhanced ongoing IL-6 and sIL-2R response, prior to therapy, was detrimental to subsequent treatment with rIL-2. Differential production and/or release of cytokines and prostaglandins, during therapy, further determined the likelihood of response to rIL-2.
