Radiation therapy is considered an optimal partner for immunotherapies. Several pre-clinical studies have demonstrated that regression of distant metastases, at remote non-irradiated sites of the body, termed the "abscopal effect", can be achieved by an appropriate timing and combination of radiation with immunotherapy. However, nearly all pre-clin...

The aim of this study was to assess...
We report the case of a 33-year-old man with a testicular tumor and multiple lung metastases. After high orchiectomy, chemotherapy was administered. Subsequently, fluoroscopy-assisted thoracoscopic resection was performed for pulmonary lesions that had decreased in size after the chemotherapy but had persisted. Because four pulmonary lesions were t...
Clinical topoisomerase I (Top1) and II (Top2) inhibitors trap topoisomerases on DNA, thereby inducing protein-linked DNA breaks. Cancer cells resist the drugs by removing topoisomerase-DNA complexes, and repairing the drug-induced DNA double-strand breaks (DSBs) by homologous recombination (HR) and non-homologous end-joining (NHEJ). Because numerou...

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is endogenously expressed in immune cells and contributes to immunosurveillance for cancer. TRAIL induces apoptosis preferentially in various cancer cells, including renal cell carcinoma (RCC) cells. In this study, the serum TRAIL level was examined using an enzyme-linked immunosorbent...
In general, 80% of advanced germ cell tumors (GCTs) with metastasis can be cured, since clinical treatment guidelines for testicular cancer has been established after the International Germ Cell Cancer Collaborative Group announcement in 1997. Of those with advanced GCTs, 20-30% of the cases are defined as 'difficult-to-treat' GCTs. In particular,...
We previously reported that the level of high mobility group protein AT-hook 1 (HMGA1) is low in androgen-dependent prostate cancer (PCa) cells (LNCaP), but is high in androgen-independent PCa cells (DU145 and PC-3) and that HMGA1 is a strong candidate gene playing a potential role in the progression of PCa. These findings have prompted us to evalu...

Testicular cancer is the most common cancer in young men and the cure rate has been approximately 80% since the introduction of cisplatin in the 1970s. BEP therapy (including bleomycin, etoposide and cisplatin) has become a standard induction therapy instead of PVB therapy (cisplatin, vinblastin and bleomycin). However, the patients with incomplete...

Human tissue kallikreins (genes, KLKs; proteins, hKs) are a subgroup of hormonally regulated serine proteases. Two tissue kallikreins, namely hK2 and hK3 (prostate-specific antigen, PSA), are currently used as serological biomarkers of prostate cancer. Human tissue kallikrein 9 (KLK9) is a newly identified member of the tissue kallikrein gene famil...
