  • The supportive care of patients receiving antineoplastic treatment has dramatically improved over the past few years and development of effective measures to prevent nausea and vomiting after chemotherapy serves as one of the most important examples of this progress. A patient who starts cancer treatment with chemotherapy lists chemotherapy-induced nausea and vomiting as among their greatest fears. Inadequately controlled emesis impairs functional activity and quality of life, increases the use of health care resources, and may occasionally compromise adherence to treatment. New insights into the pathophysiology of chemotherapy-induced nausea and vomiting, a better understanding of the risk factors for these effects, and the availability of new antiemetic agents have all contributed to substantial improvements in emetic control. This review focuses on current understanding of chemotherapy-induced nausea and vomiting and the status of pharmacological interventions for their prevention and treatment.

  • Paclitaxel (PTX) is an antineoplastic agent approved for the treatment of ovarian and breast carcinomas. However, the use of paclitaxel as an anticancer drug is limited by its extremely poor water solubility (below $0.3\;{\mu}g/mL$). Furthermore, it has very low bioavailability when administered orally because paclitaxel is a substrate of P-glycoprotein (P-gp) efflux pump. In this study, buccal delivery of PTX was investigated as one of the alternatives for PTX delivery. Ethanol and glyceryl monooleate (GMO) were selected as permeation enhancing agents to increase solubility and permeation across buccal mucosa of PTX. At the different concentrations of ethanol solution ($30{\sim}70\;w/w\;%$), PTX permeation was studied, followed effects of GMO in the concentration range of $2.5{\sim}25%$ with ethanol vesicle. The transbuccal ability of PTX was evaluated in vitro using Franz diffusion cells mounted with rabbit buccal mucosa. As a result, incorporation of PTX into ethanol vesicle with GMO significantly enhanced the PTX permeation in rabbit buccal mucosa. Particularly, the mixtures of ethanol:water:GMO at the ratio of 50:47.5:2.5 showed the most excellent enhancing ability. The results showed a promising possibility for buccal delivery of PTX.

  • Purpose: The purpose of this study was to identify the degree of menopause symptoms and associated factors in patients with breast cancer who were receiving hormone therapy. Methods: Data were collected with questionnaires from 150 patients with breast cancer who had been on hormone therapy at a hospital in Seoul. Data were analyzed with the t-test, ANOVA, and Pearson correlation coefficient to compare the degree of menopause symptoms by demographic, clinical and psychological factors. Results: The mean menopause symptoms score was $13.39{\pm}7.97$. Most participants reported having hot flushes and sweating (75.3%), physical and mental exhaustion (82.7%) and sexual problems (64.7%). Menopause symptoms and depression were correlated with each other (p<.01). Somato-vegetative symptoms were different significantly by age, menopausal status at time of operation, occupation and tumor. Psychological symptoms were different significantly by marital status, operation type and chemotherapy. Urogenital symptoms were different significantly by prior history of cancer, occupation, operation type and radiation therapy. Conclusion: These findings can be used to provide tailored nursing interventions by identifying high risk groups for menopausal symptom among breast cancer patients receiving hormone therapy.

  • Purpose: This study was done to identify conditions of cancer patients who visited an emergency department (ED) with the side effects of chemotherapy. Methods: Data were collected retrospectively from medical records of 294 cancer patients who visited a tertiary hospital in 2009 for treatment of side effects of chemotherapy. Records were reviewed for characteristics of participants and side effects of chemotherapy. Data were analyzed using SPSS software. Results: ED Triage grade 3 was 81.6%. The hospitalization ratio was 72.8%, and 6.5% died during the admission. Most frequent side effects were thrombocytopenia (80.6%), anemia (74.5%), pain (52.0%), neutropenia (50.7%), and leucopenia (46.3%). The hospitalization group showed more severe leucopenia than the discharge group (p=.020). Patients in the group who died had higher scores for dyspnea compared to patients discharged or hospitalized (p<.05). Conclusion: Results of the study suggest that there is a special need to develop a system to manage side effects of chemotherapy. Also it is necessary to provide appropriate care and treatment with prompt initial evaluation when cancer patients with side effects of chemotherapy present in the ED. More effective educational discharge programs should also be developed to help these patients cope with various side effects of chemotherapy.

  • Purpose: To investigate factors influencing the evaluation of background parenchymal enhancement (BPE) at follow-up breast magnetic resonance imaging (MRI) after adjuvant endocrine therapy. Materials and Methods: One hundred twelve women with breast cancer and MRI of the contralateral unaffected breast before and after endocrine therapy were identified. Two readers in consensus performed blinded side-by-side comparison of BPE (minimal, mild, moderate, and marked) before and after therapy with categorical scales. Age, body mass index, menopausal status, treatment regimen (selective estrogen receptor modulator or aromatase inhibitor), chemotherapy, follow-up duration, BPE at baseline MRI, MRI field strength before and after therapy, and recurrence were analyzed for their influences on decreased BPE. Results: Younger age, premenopausal status, treatment with selective estrogen receptor modulator, MRI field strength, and moderate or marked baseline BPE were significantly associated with decreased BPE. In multivariate analysis, MRI field strength and baseline BPE showed a significant association. Conclusion: MRI field strength and baseline BPE before and after therapy .were associated with decreased BPE at post-therapy, follow-up MRI.

  • The incidence of childhood cancer is greatest in the first year of life. Early diagnosis and advances in medicine have significantly improved outcomes of treatment resulting in higher survival rate; however, this progress comes at the expense of a higher incidence of adverse side effects because of more aggressive antineoplastic treatment strategies. The oral cavity, a trauma-prone environment, is extremely sensitive to toxicities from antineoplastic agents. Oral health care specialists, including pediatric and hospital dentists can support the oncology team by providing basic oral care, implementing oral care protocols, delivering emergency dental treatment, and assisting and/or managing oral complications from cancer therapy. This article covers the considerations in the dental management of pediatric patients undergoing cancer treatment, specifically chemotherapy, radiotherapy, and hematopoietic stem cell transplantation.

  • Objective : To study the physiochemical characteristics of podophyllotoxin (PPT) conjugated stearic acid grafted chitosan oligosaccharide micelle (PPT-CSO-SA), and evaluate the ability of the potential antineoplastic effects against glioma cells. Methods : PPT-CSO-SA was prepared by a dialysis method. The quality of PPT-CSO-SA including micellar size, zeta potential, drug encapsulation efficiency and drug release profiles was evaluated. Glioma cells were cultured and treated with PPT and PPT-CSO-SA. The ability of glioma cells to uptake PPT-CSO-SA was observed. The proliferation of glioma cells was determined by 3-[4, 5-dimethyl-2-thiazolyl]-2, 5-diphenyl-2H-tetrazolium bromide (MTT) assay. The apoptosis and morphology of U251 cells were observed by 4',6-Diamidino-2-phenylindole dihydrochloride (DAPI) dye staining. Cell cycle analysis was performed by flow cytometry. The migration ability of U251 cells was determined by wound healing test. Results : PPT-CSO-SA had nano-level particle size and sustained release property. The encapsulation efficiency of drug reached a high level. The cellular uptake percentage of PPT in glioma cells was lower than that of PPT-CSO-SA (p<0.05). The inhibitory effect of PPT-CSO-SA on glioma cells proliferation was significantly stronger than that of PPT (p<0.05). The morphologic change of apoptosis cell such as shrinkage, karyorrhexis and karyopyknosis were observed. The percentage of U251 cells in G2/M phase increased significantly in the PPT-CSO-SA group compared with PPT group (p<0.05). Compared with the PPT group, the cell migration ability of the PPT-CSO-SA group was significantly inhibited after 12 and 24 hours (p<0.05). Conclusion : PPT-CSO-SA can effectively enhance the glioma cellular uptake of drugs, inhibit glioma cells proliferation and migration, induce G2/M phase arrest of them, and promote their apoptosis. It may be a promising anti-glioma nano-drug.

  • Advanced incurable cancer patients receive palliative chemotherapy to prolong their life and improve quality of life. However, physicians should assess the timing to discontinue the treatment, especially near the final months of life, as palliative chemotherapy may accompany considerable toxicity. Even though there are no clear guidelines regarding the withdrawal timing for anticancer treatment in palliative setting, it is important clarify the issue for quality of care for advanced cancer patients. Here, we present two patients who received palliative chemotherapy for advanced colon cancer and non-small cell lung cancer, respectively. In both cases, it was jointly determined to stop palliative chemotherapy, and best efforts are made to relieve troublesome symptoms. The cases and up-to-date literature review will highlight the importance of the timing of discontinuation of cancer treatments when changes are being made to the health care system and hospice and palliative medicine is taking root in Korea.

  • Purpose: The purpose of the study was to identify degrees of pain, menopause symptoms, and quality of life, and to identify factors influencing quality of life of patients with breast cancer who were on hormone therapy. Methods: A cross-sectional survey design was utilized. Data were collected using questionnaires from 110 patients with breast cancer who had been on hormone therapy for 3 months or more and were being treated at a university hospital in Seoul. Data were analyzed using ${\chi}^2$-test, t-test, ANOVA, Pearson correlation coefficient and multiple linear regression. Results: Mean age of the participants was 53.56 (SD=6.67) and 54 (51.4%) had stage 0 or I at the time of diagnosis. Most of the participants reported having pain and menopause symptoms (88.2% and 95.5% respectively). The mean score for quality of life was $87.84{\pm}21.17$. Pain, menopause symptoms and quality of life had strong correlations with each other (p<.005). Quality of life was explained by menopause symptoms (${\beta}$= -.71), economic status (${\beta}$=.20) and occupation (${\beta}$=.16). Conclusion: The results of the study suggest that menopause symptoms should be incorporated into oncologic nursing care to improve quality of life of patients with breast cancer on hormone therapy.
