Radiotherapy is an important part of modern cancer management for many malignancies, and enhancing the radiosensitivity of tumor cells is critical for effective cancer therapies. The Notch signaling pathway plays a key role in regulation of numerous fundamental cellular processes. Further, there is accumulating evidence that dysregulated Notch activity is involved in the genesis of many human cancers. As such, Notch inhibitors are attractive therapeutic agents, although as for other anticancer agents, they exhibit significant and potential side effects. Thus, Notch inhibitors may be best used in combination with other agents or therapy. Herein, we describe evidence supporting the use of Notch inhibitors as novel and potent radiosensitizers in cancer therapy.

The usage and types of chemicals being developed, with diversified new exposure of workers, are of natural concern to occupational disease. In Korea, with industrialization, application of many chemicals has increased. A large proportion of mortality and disease is due to cancer, and the causal hazardous agents include chemical agents, like heavy metals and so on. Due to the long latency period with malignancies and the fact they are usually found after workers' retirement, it is suggested that management policies must be established to prevent occupational cancers occurring among workers in Korea. To give a general description about the efforts to prevent the occupational cancer with exposure to chemicals, articles on the trends of occupational cancers were reviewed and summarized with related research and efforts for prevention in Korea. It is important to improve the understanding of occupational cancer and help to maintain sustainable and appropriate measures to guarantee workers safety and health.

Of all gynecologic cancers, endometrial cancer is the most common cancer in the US and Europe. In addition, it is presently the second most common gynecologic cancer in the world. As a result of increasing menopausal, obese and tamoxifen use women, the incidence of the cancer seems to be on the increase. Surgery is the major treatment, whereas postoperative radiation therapy in high-intermediate risk patients many prevent locoregional recurrence. Adjuvant chemotherapy can improve progression free survival in advanced or recurrent cancers. Molecular targeted therapies are now a focus of attention including anti-vascular endothelial growth factor (VEGF), mammalian target of rapamycin (mTOR) inhibitor and tyrosine kinase inhibitor (TKI). They may provide useful future strategies for control of endometrial malignancies in developing countries and across the world.

Fertility preservation plays a central role in cancer care since an increasingly large number of cancer patients are surviving as a result of improvements in diagnostic and therapeutic strategies. Physicians who take part in the initial diagnosis and management of gynecologic cancer should understand the importance of fertility preservation. Since indications for fertility preservation are limited to early-stage gynecologic cancer, a surgeon must carefully consider each indication. Before performing fertility-sparing surgery, health professionals should compare its oncologic and pregnancy outcomes with those of other standard treatments. Individualized treatment strategies should be delivered depending on the patient's situation, and physicians should provide timely information and appropriate counseling.

Malignant mixed tumor of the parotid gland account for a very small number of the head and neck malignancies. Authors had experienced the recurrent malignant mixed tumor on 70 years old female patient. The first surgical removal was done before the 5years ago and at that time, histological diagnosis was the malignant mixed tumor. We had done the second operation, and histopathological diagnosis was malignant mixed tumor.

The diagnostic accuracy of routine cytological preparations from effusions ranges from 60% to 70%. Immunohistochemical markers, especially tumor-associated antigens, have been successfully employed to increase diagnostic sensitivity in effusion cytology. However, more than two different antibodies in diagnosis of effusions are needed. In the view of prevalence of abnormalities of p53 gene in human malignancies we investigated the diagnostic usefulness of demonstration of p53 protein immunoreactivity in distinguishing benign changes versus malignant processes in effusions. p53 protein expression was studied immunohistochemically in 76 effusions(28 malignant and 48 benign) using anti-human p53 antibody p53 immunoreactivity was identified in 19 of 28(67.9%) malignant effusions. In contrast, no p53 immunoreactivity was observed in all benign effusions. A specificity of 100% and a sensitivity of 67.9% were observed. These results suggest that immunohistochemical detection of p53 protein seems to be helpful in distinguishing benign changes versus malignant processes in effusions, although its principal limitation is its relatively low sensitivity.

Ex vivo hematopoietic cells can treat patients suffering from hematopoietic malignancies using bone marrow transplantation therapies. A initial cell density of $1.5{\times}10^6cells/ml$ and a growth factors of IL-3(5ng/ml), SCF(5ng/ml) and FL(25ng/ml) result in a 3.6-fold expansion of LTC- IC but a unexpansion of total cells.

Translocations involving chromosome 21q22 are frequently observed in hematologic malignancies including acute myeloid leukemia (AML), most of which have been known to be involved in malignant transformation through transcriptional dysregulation of Runt-related transcription factor 1 (RUNX1) target genes. Nineteen RUNX1 translocational partner genes, at least, have been identified, but not Homeobox A (HOXA) genes so far. We report a novel translocation of RUNX1 into the HOXA gene cluster in a 57-year-old female AML patient who had been diagnosed with myelofibrosis 39 months ahead. G-banding showed 46,XX,t(7;21)(p15;q22). The involvement of RUNX1 and HOXA genes was confirmed by fluorescence in situ hybridization.

Sarcoidosis is an inflammatory disease involving multiple-organs with an unknown cause. The new onset of sarcoidosis associated with therapeutic agents has been observed in 3 clinical settings; tumor necrosis factor antagonists in autoimmune rheumatologic diseases, interferon alpha with or without ribavirin in patients with chronic hepatitis C or melanoma, and antineoplastic agent-associated sarcoidosis in patients with hematologic malignancies. Here, we report a female patient who developed sarcoidosis after capecitabine treatment as an adjuvant chemotherapy for sigmoid colon cancer. To our knowledge, this is the first report of a capecitabine-induced sarcoidosis.

Small cell carcinoma of larynx has been reported as a rare disease occurring in 0.5% of larynx cancer. This tumor is known as one of the most lethal of all malignancies and associated with early recurrence and distant metastasis, leading into death. We experienced a case of a 70-year old male patient, who had admitted for sore throat and dysphagia and diagnosed as small cell carcinoma of larynx. We present small cell carcinoma of larynx with a brief review of literature.
