  • Cisplatin is useful for various cancers including advanced testicular and ovarian cancers. However, clinical use of cisplatin has been limited due to its dose-related neplrotoxicity. Transport studies across the membrane vesicles were performed to study the cisplatin nephrotoxicity. In these experiments, after cisplatin was administered to adult male New Zealand White rabbits, basolateral membrane (BLM) vesicles were prepared from the renal cortex. Para-aminohippurate (PAH) uptakes through BLM vesicles were measured to examine the interactioln of cisplatin on the transports of the substrates. As results of the uptake experiments using the vesicle systems, cisplatin had little effects on PAH transport through BLM vesicle. In conclusion, cisplatin did not cause the damage of basolateral membranes.

  • Idiopathic inflammatory myopathy (IIM) is known for its association with malignant diseases. Moreover, various solid organ malignancies, such as ovarian, breast, lung, esophageal, stomach, and colorectal cancers, have been reported to occur with IIM. Furthermore, its relationship with hematologic malignancies, including non-Hodgkin lymphoma, myeloma, and leukemia, has been reported. However, to date, IIM related to pancreatic cancer has scarcely been reported, particularly in patients with polymyositis (PM). Therefore, here we report a case of PM developed immediately after the diagnosis of pancreatic ductal adenocarcinoma.

  • Background: Epithelial ovarian cancer (EOC) is the commonest malignancy involving the ovaries. Maximum surgical cytoreduction (MCR) followed by adjuvant taxane-platinum chemotherapy are the standard of care treatments. Aims: To study treatment outcomes of EOC patients that were maximally cyto-reduced and received adjuvant paclitaxel-carboplatin (PC) chemotherapy. Materials and Methods: This retrospective cohort study included 174 patients with EOC treated at the Egyptian National Cancer Institute between 2006 and 2010. For inclusion, they should have had undergone MCR with no-gross residual followed by adjuvant PC chemotherapy. MCR was total abdominal hysterectomy/bilateral salpingo-oophorectomy [TAH/BSO] or unilateral salpingo-oophorectomy [USO] plus comprehensive staging. Results: The median age was 50 years. Most patients were married (97.1%), had offspring (92.5%), were postmenopausal (53.4%), presented with abdominal/pelvic pain and swelling (93.7%), had tumors involving both ovaries (45.4%) without extra-ovarian extension i.e. stage I (55.2%) of serous histology (79.9%) and grade II (87.4%). TAH/BSO was performed in 97.7% of cases. A total of 1,014 PC chemotherapy cycles were administered and were generally tolerable with 93.7% completing 6 cycles. Alopecia and numbness were the commonest adverse events. The median follow up period was 42 months. The 2-year rates for disease free survival (DFS) and overall survival (OS) were 70.7% and 94.8%, respectively. The respective 5-year rates were 52.6% and 81.3%. Advanced stage and high-grade were significantly associated with poor DFS and OS (p<0.001). Age >65 years was associated with poor OS (p =0.008). Using Cox-regression, stage was independent predictor of poor DFS and OS. Age was an independent predictor of poor OS.

  • AKT is a signal transduction protein that plays a central role in the tumorigenesis. There are 3 mammalian isoforms of this serine/threonine protein kinase-AKT1, AKT2, and AKT3-showing a broad tissue distribution. We first discovered 2 novel polymorphisms (AKT2 -9826 C/G and AKT3 -811 A/G), and we confirmed 6 known polymorphisms (AKT2 -9473 C/T, AKT2 -9151 C/T, AKT2 -9025 C/T, AKT2 -8618G/A, AKT3 -675 A/-, and AKT3 -244 C/T) of the AKT2 and AKT3 promoter region in 24 blood samples of Korean lung cancer patients using direct sequencing. To evaluate the role of AKT2 and AKT3 polymorphisms in the risk of Korean lung cancer, genotypes of the AKT2 and AKT3 polymorphisms (AKT2 -9826 C/G, AKT2 -9473 C/T, AKT2 -9151 C/T, AKT2 -9025 C/T, AKT2 -8618G/A, and AKT3 -675 A/-) were determined in 360 lung cancer patients and 360 normal controls. Statistical analyses revealed that the genotypes and haplotypes in the AKT2 and AKT3 promoter regions were not significantly associated with the risk of lung cancer in the Korean population. These results suggest that polymorphisms of the AKT2 and AKT3 promoter regions do not contribute to the genetic susceptibility to lung cancer in the Korean population.

  • Propolis is a natural product collected from plants by honey bees product used extensively in traditional medicine for its antioxidant, anti-inflammatory, immunomodulatory and anti-cancer effects. Propolis exhibits a broad spectrum of biological activities because it is a complex mixture of natural substances. Ovarian cancer is the second most common newly diagnosed cancer from all cancers among women in Korea and the leading cause of death from gynecological malignancies. While most ovarian cancer patients initially respond to surgical debulking and chemotherapy, patients later succumb to the disease. Thus, there is an urgent need to test novel therapeutic agents to counteract the high mortality rate associated with ovarian cancer. In this study, we investigated the anti-cancer properties and the active mechanism of Australian propolis in human epithelial ovarian cancer A2780 cells. Our data revealed that propolis showed a cytotoxic activity in a dose-dependent manner. Flow cytometric analysis for cell cycle arrest and apoptosis using propidium iodide staning and annexin V-FITC indicated that propolis could induce cycle arrest in the G0/G1 phase and apoptosis in a dose-dependent manner on human epithelial ovarian cancer cells. These results suggest that the Australian propolis is potential alternative agent on ovarian cancer prevention and treatment.

  • Codonopsis lanceolata L. (Campanulaceae) has long been used in traditional Korean medicine to treat bronchitis, cough, and inflammatory diseases, however, the efficacy of anti-tumor activities remains to be defined. In this study the effects of Codonopsis lanceolata (C. lanceolata) on proliferation, migration and adhesion in lung (A549, H1299) and ovarian cancer (SKOV-3) cells were investigated. To assess and compare the pharmacological effects and production places of C. lanceolata, the ethanolic extracts of C. lanceolata from different places in Korea (Hongseong, Yecheon, Yeongwol, Yanggu, Gangjin, and Hoengseong) were prepared. The extract from Hoengseong county did have only marginal anti-proliferative activity in all the cell lines tested, however, other extracts had little or no effect on cell proliferation. The extracts from Hongseong, Gangjin or Hoengseong county had partial anti-migratory activity in lung cancer cells, but not in ovarian cancer cells. In addition, the extract from Hoengseong county had partial anti-adhesive activity in ovarian cancer cells, however, other extracts did not affect cell adhesion in both lung and ovarian cancer cells. Taken together, these findings provide the first description of anti-tumor efficacy of C. lanceolata from different production places in Korea, and suggest that C. lanceolata from Hoengseong county may have therapeutic potential in lung and ovarian cancers.

  • Background: Variation in cancer incidence in geographical locations is due to different lifestyles and risk factors. Diet and socio-economic position (SEP) have been identified as important for the etiology of cancer but patterns are changing and inconsistent. The aim of this study was to investigate correlations of the incidence of common cancers with food groups, total energy, smoking, and SEP. Materials and Methods: In an ecological study, disaggregated cancer data through the National Cancer Registry in Iran (2008) and dietary intake, smoking habits and SEP obtained through a population based survey within the Urban Health Equity Assessment (Urban-HEART) project were correlated across 22 districts of Tehran. Results: Consumption of fruit, meat and dairy products adjusted for energy were positively correlated with bladder, colorectal, prostate and breast and total cancers in men and women, while these cancers were adversely correlated with bread and fat intake. Also prostate, breast, colorectal, bladder and ovarian cancers had a positive correlation with SEP; there was no correlation between SEP and skin cancer in both genders and stomach cancer in men. Conclusions: The incidence of cancer was higher in some regions of Tehran which appeared to be mainly determined by SEP rather than dietary intake. Further individual data are required to investigate reasons of cancer clustering.

  • Background/Objectives: Cancers of the abdominal or pelvic organ rarely metastasize to the cervical lymph nodes. Although it indicates distant metastasis, perceivable prolongation of survival or cure may be possible in selected cases. We sought to identify patients with cervical metastasis from cancers below the diaphragm and identify patients who may benefit from aggressive treatment. Materials & Methods: From 2009 to 2017, patients with pathologically confirmed metastatic cervical lymph nodes originating from below the diaphragm were included for analysis. Patient demographics, cancer characteristics, treatment course, and clinical outcomes were analyzed. Results: 208 patients were identified. Left supraclavicular node (Virchow's node) was the most frequently involved. Irrespective of treatment, survival for uterine cervical and ovarian cancers was significantly longer than that of other primaries. Patients with isolated cervical metastasis (oligometastasis) had significantly longer median survival compared to patients with concomitant bone, lung, brain, and mediastinal metastases. Conclusion: Although cervical metastasis from cancers of the abdominal and pelvic organ represent distant metastasis, patients with uterine cervix and ovary primary and oligometastatic lesions may benefit from aggressive treatment. Prudent patient selection and further investigation is warranted.
