  • The abscopal effect refers to the phenomenon in which local radiotherapy is associated with the regression of metastatic cancer that is distantly located from the irradiated site. Here, we present a case of a patient with advanced gastric cancer and brain metastases who was successfully treated with brain radiotherapy and anti-programmed death-1 (PD-1) therapy-induced abscopal effect. Although anti-PD-1 therapy alone could not prevent disease progression, the metastatic lesions in the brain and also in the abdominal lymph node showed a drastic response after brain radiotherapy and anti-PD-1 therapy. To our knowledge, this is the first reported case of successful treatment of advanced gastric cancer with multiple brain and abdominal lymph node metastases, possibly through anti-PD-1 therapy combined with brain radiotherapy-induced abscopal effect. We suggest that the combination of brain radiotherapy and anti-PD-1 therapy may be considered as a therapeutic option for advanced gastric cancer, especially when there is brain metastasis.

  • Aim: To compare drainage alone or combined with anti-tumor therapy for treatment of obstructive jaundice caused by recurrence and metastasis after primary tumor resection. Materials and Methods: We collect 42 patients with obstructive jaundice caused by recurrence and metastasis after tumor resection from January 2008 - August 2012, for which percutaneous transhepatic catheter drainage (pTCD)/percutaneous transhepatic biliary stenting (pTBS) were performed. In 25 patients drainage was combined with anti-tumor treatment, antineoplastic therapy including intra/postprodure local treatment and postoperative systemic chemotherapy, the other 17 undergoing drainage only. We assessed the two kinds of treatment with regard to patient prognosis. Results: Both treatments demonstrated good effects in reducing bilirubin levels in the short term and promoting liver function. The time to reobstruction was 125 days in the combined group and 89 days in the drainage only group; the mean survival times were 185 and 128 days, the differences being significant. Conclusions: Interventional drainage in the treatment of the obstructive jaundice caused by recurrence and metastasis after tumor resection can decrease bilirubin level quickly in a short term and promote the liver function recovery. Combined treatment prolongs the survival time and period before reobstruction as compared to drainage only.

  • Purpose : Epithelial-to-mesenchymal transition (EMT) is recognized as an important cellular response in metastatic proceduresand characterized by loss of cellular polarity as well as gain of mesenchymal features, which enables migration and invasion. Hepatocellular carcinoma (HCC) is one of the most common primary carcinomas in the liver and exhibits a poor prognosis due to frequent extrahepatic metastasis. Taraxacum officinale has been used for a long time in oriental medicine because of its various pharmacological activitiessuch as anti-rheumatic, anti-inflammatory, antioxidative, and anticarcinogenic activities. In this study, the anti-metastatic activity of T. officinale water extract (TOWE) and ethanol extract (TOEE) was investigated through the regulation of EMT in the Huh7 cells. Methods : The effects of TOWE and TOEE on migratory and invasive activities were investigated by wound healing and in vitro invasion assays. Western blot analysis was also applied to analyze protein expression levels associated with EMT and their upstream transcription factors in Huh7 cells. Results : TOWE and TOEE treatment potently inhibited migration and invasion of Huh7 cells compared to the untreated group. Both extracts treatment inhibited protein expression levels of N-cadherin, matrix metalloproteinase (MMP)-9, and vimentin while E-cadherin was significantly accelerated. In addition, the activated status of transcription factors, Snail, nuclear factor (NF)-κ B, and zinc finger E-box binding homeobox (ZEB)1 was also inhibited with statistical significance. In comparison to both extracts, TOEE more potently attenuated migration, invasion, and EMT markers as well as their transcription factors in Huh7 cells than TOWE, which means that TOEE might possess more functional phytochemicals than TOWE. Conclusion : Consequently, TOWE and TOEEattenuated metastatic activity of hepatocellular carcinoma through the regulation of EMT markers and their transcription factors in Huh7 cells, which means that T. officinale might be a promising strategy for a chemopreventive agent against HCC metastasis.

  • To study the effects of anti-cancer, anti-metastasis and immune response improvement of aqua-acupuncture with Cistanches Herba infusion solution, we used Cistanches Herba infusion solution(taken by water-alcohol method) put into Chung-wan(CV12) and Chok-Samni(S36) of BALB/c or C57BL/6 which are corresponding to human body. We observed the cytotoxicity, the effect on the expression of MMP-9 gene, the ability to control cancer cell proliferation, change of body weight, surviving number, MST, ILS, changes in amount of WBC, RBC, PLT, total protein, creatinine, glucose and LDH, weight of spleen, number of pulmonary colony, histological analysis on tissue metastasis of lung and liver, splenic cell proliferation, the expression of cytokine gene, the number of $CD4^+$, $CD8^+$, $CD19^+$ and NK cell, and concluded like this. The results were obtained as follows : 1. The cytotoxicity about B16-F10 cell line of $2^0$, $2^{-1}$, $2^{-2}$, $2^{-5}$ diluent groups in Cistanches Herba infusion solution treatment was inhibited significantly, compared with control group. 2. The cytotoxicity about HT1080 cell line of $2^0$, $2^{-1}$, $2^{-2}$, $2^{-3}$, $2^{-5}$, $2^{-8}$ diluent groups in Cistanches Herba infusion solution treatment was inhibited significantly, compared with control group. 3. The effect on expression of MMP-9 gene was decreased in all the sample groups, compared with control group. 4. The effect on the control-ability on the cancer cell proliferation showed cytotooicity significantly in $2^0$, $2^{-1}$, $2^{-2}$, $2^{-3}$, $2^{-4}$, $2^{-5}$ diluent groups. 5. S-180 cancer cell line transplants in BALB/c mice were inhibited significantly in weight increase in all the sample groups, compared with control group. The surviving number increased in almost sample groups, except one group put into Chok-Samni(S36) with 20% Cistanches Herba infusion solution treatment group that showed same number of the control group. 6. S-180 cancer cell line transplants in BALB/c mice showed high MST and ILS significantly in almost sample groups, compared with control group. But one group put into Chok-Samni(S36) with 20% Cistanches Herba infusion solution treatment group showed low MST and ILS than control group. 7. The sample group injected in vein with B16-F10 cancer cell line in C57BL/6 mice showed increased ILS compared with control group significantly in anti-metastasis test. 8. The sample group injected in vein with B16-F10 cancer cell line in C57BL/6 mice were increased significantly in the number of WBC and glucose, and decreased significantly in the amount of LDH, compared with control group. However, there's no significant increase or decrease in number of RBC, PLT, total protein and creatinine. 9. We couldn't find any significant relation in spleen weight of the sample group. 10. In pulmonary colony, sample group was decreased significantly, compared with control group. 11. Histological analysis of sample group inhivited compared with that of control group in both of lung and liver. 12. In immune system, all the sample groups showed having more relevancy to the effect on splenic cell proliferation than normal group. 13. The effect on cytokine gene expression of all the sample groups were increased than control group. 14.

  • Skin metastasis from papillary thyroid carcinoma is extremely rare. Due to similar histopathologic features, it is difficult to differentiate skin metastatic papillary thyroid carcinoma and some primary skin neoplasms without a clinical history. However, most of metastatic skin lesions showed a strong reactivity to the antithyroglobulin antibodies unlike primary skin neoplasms. Metastatic skin lesions must be completely removed and radiotherapy can be added. Investigators reported that prognosis of skin metastases from thyroid carcinoma is dismal and the average survival after it's diagnosis was only 19 months because distant metastases were often discovered at diagnosis of skin metastasis or during follow-up period. We report a case of skin metastasis from tall cell variant of papillary thyroid carcinoma. In our case, the anti thyroglobulin antibodies measured from cystic fluid from a skin lesion was more than 2000 IU/ml. Skin metastasis was diagnosed at 20 months after primary surgery for thyroid cancer and brain metastasis at 12 months after diagnosis of skin metastasis. Although skin metastasis is an ominous prognostic indicator in patients with thyroid carcinoma, a radical treatment for skin lesions and early diagnosis of distant metastasis could provide a chance to the patients to improve their survival.

  • Intra-tumoral hypoxia is an environment that promotes tumor cell migration, angiogenesis and epithelial-mesenchymal transition that accounts for a major mechanism of metastasis. Chloroquine potentially offers a new therapeutic approach with an 'old' drug for effective and safe cancer therapies, as it exerts anti-metastatic activity. We investigated the inhibitory effect of chloroquine on cholangiocarcinoma (CCA) cell migration under cobalt chloride ($CoCl_2$)-stimulated hypoxia. We showed that chloroquine suppressed CCA cell migration under hypoxic-mimicking conditions on exposure to $100{\mu}M$ $CoCl_2$. Moreover, chloroquine stabilized the protein level of prolyl hydroxylase domain proteins (PHD-2) but reduced the levels of hypoxic responsive proteins such as hypoxia-inducible factor (HIF-$1{\alpha}$) and vascular endothelial growth factor (VEGF). It also suppressed epithelial mesenchymal transition (EMT) by increasing the ratio of E-cadherin to N-cadherin under hypoxic conditions. In conclusion, chloroquine can inhibit hypoxia-stimulated metastasis via HIF-$1{\alpha}$/VEGF/EMT which may serve as a useful additional strategy for CCA therapy.

  • Objectives : This experiment was conducted to evaluate the inhibitory effects against lung metastasis and promotion of splenocytes by water-soluble components from five mushrooms extracts (WEFM): Garnoderma frondosa, Corious versicolor, Codyceps militaris, Hericium erinaceus and Lentinula edodes. Methods : Colon 26-L5 carcinoma cells were injected through the tail vein to induce lung metastatic cancer. Changes in weight of lung were observed and cytokine level was analyzed to evaluate immunological changes. Results : Oral administration of WEFM resulted in a significant inhibition of lung metastasis after intravenous injection of colon 26-L5 cells in a dose-dependent manner. There was also a significant increase in T cell and B cell mitogenic stimuli and production of IFN-g by splenocytes stimulated with Con A compared to untreated controls. Conclusion : WEFM may have anti-tumor activities via Th1-type dominant immune responses.

  • Objectives: This study was designed to investigate intestinal immune system activation and anti-metastatic effect on cancer cells by orally administered extracts of Boyanghwano-tang. Methods: To observe immunomodulating effects of Boyanghwano-tang on Peyer's patch cells, we measured cytokines GM-CSF, IL-4. In addition to observing effects of Boyanghwano-tang on hematopoiesis, we measured proliferation of bone marrow cells mediated by Peyer's patch cells in vitro. IgA induction activated in intestinal content and serum was measured to observe the effect of orally administered Boyanghwano-tang on mucosal immune system. After administering ovalbumin (OVA) with Boyanghwano-tang, Proliferation of Peyer's patch cell was measured to investigate gut immunostimulatory effect. Anti-metastatic experiments were conducted in vivo mouse model by using colon 26-M3.1 carcinoma cell. Results: The amounts of GM-CSF and IL-4 in the culture supernatant of Peyer's patch cells were significantly increased compared to the control group. The proliferation of bone marrow cell was significantly up-regualted with Boyanghwano-tang. These results indicate that oral administration of Boyanghwano-tang enhances the secretion of hematopoietic growth factors such as GM-CSF and IL-4 from Peyer's patch cells, and these cytokines also act on modulator of bone marrow cell proliferation. After orally administering OVA with Boyanghwano-tang, IgA induction and Proliferation of peyer's patch cell was up-regulated with Boyanghwano-tang. These results means orally administered Boyanghwano-tang activates intestinal immune system and has an inhibitory effect on tumor metastasis. In addition, We found that orally administered Boyanghwano-tang significantly inhibited tumor metastasis in vivo. Conclusions: Orally administered Boyanghwano-tang appears to have considerable activity on the anti-metastasis by activation of immune system.

  • Background and Purpose : Oral squamous cell carcinoma (OSCC) is one of the most aggressive tumors of the head and neck area. OSCC is known to preferentially metastasize via lymphatic system, and resulting cervical lymph node metastasis is the most reliable of treatment failure. But the biological mechanism of the regional nodal metastasis is not clear. So, we determined metastasis-related factors in orthotopic nude mouse models of OSCC. Experimental Design : Two cell lines-KB and YD-10B cells, established from human oral mucosal squamous cell carcinoma, were xenografted into the tissue space of athymic murine mouth floor. The mice were followed for tumor development and growth, the murine tumors were examined histopathologically for local invasion or regional or distant metastasis. Finally, we performed immunohistochemical assays with antiepithelial growth factor (EGF), EGF receptor (EGFR), phosphorylated EGFR (pEGFR), and anti-vascular endothelial growth factor (VEGF), VEGF receptor (VEGFR)-2, phosphorylated VEGFR-2/3 (pVEGFR-2/3) antibodies. We also determined the microvessel density. Results : Transplantation of human OSCC tumor cells into the mouth floor successfully resulted in the formation of orthotopic tumors. KB cell line showed significantly higher tumor proliferation and higher nodal metastatic potential than YD-10B cell line. Furthermore, immunohistochemical staining demonstrated higher expression of EGFR/pEGFR, VEGF, and pVEGFR-2/3 as well as higher microvessel density in KB murine tumors than in YD-10B murine tumors. Conclusion : An orthotopic model of OSCC in athymic mice was established which copies the cervical lymph nodal metastasis of human OSCC. Our mouth floor model should facillitate the understanding of the molecular pathogenesis of cervical nodal metastasis of OSCC.
