Urine measurements by MNR were made for 25 persons including cancer and non-cancer patients. The aromatic proton signals of NMR wer observed much more often in cancer patients' urine than non-cancer patients' one. To compare the amount of the phenolic compounds excreted in urine between cancer and non-cancer patient, urine analysis by HPLC with UV detector was performed. Total peak area and major peak areas of cancer patients' urine wer emuch greater than those of non-cancer patients' one. To check the phenolic compound excreted in urine, a new jellied reagent named Gift reagent which was based on Millon's reagent, was developed for urine color reaction. When the reagent was tested, the sensitivity and specificity for urine samples of 69 persons including cancer and non-cancer patients were measured by 85.3% and 91.4%, respectively, indicating that the Gift reagent afford a possibility of cancer diagnosis.

Background: HER2 expression in the primary tumor and its lymph node metastases vary in gastric cancer, reflecting intratumoral heterogeneity. This finding also suggests that proliferation of a different clone in metastatic nodes is possible. In the current study, we aimed to determine the cause of discordance in HER-2 expression in the primary tumor and lymph node metastases for patients with gastric cancer. Materials and Methods: Eighty-one patients with gastric cancer who had undergone radical gastrectomy and were found to have lymph node metastasis upon pathological examination were included. Histopathological samples were obtained from biopsies obtained during patient gastrectomies and lymph node dissection. HER2 status was evaluated by both immunohistochemistry (IHC) and silver in situ hybridization (SISH). Results: Sixty-four (79%) patients were SISH (-), while 17 (21%) were SISH (+) in the primary tumor. However, in metastatic lymph nodes, HER2 status was SISH positive in 5 (28.3%) of the 64 SISH (-) primary tumor specimens. One of the 17 SISH (+) primary tumors was SISH (-) in the metastatic lymph nodes. Thus, SISH results for HER2 in both primary tumors and lymph node metastases were comparable, showing a concordance of 92.5%. In total, six patients demonstrated discordance between the primary tumor and lymph node metastases. The prevalence of HER2 discordance was significantly higher for patients in the pN2 and N3 stages (p=0.007). Although discordant patients had worse survival rates than concordant patients, the differences were not significant (p>0.05).Conclusions: Our study indicates that the frequency of concordance in HER2 status, as determined by IHC or SISH, is high in primary tumors and their corresponding lymph node metastases for patients with gastric cancer. If there is a discrepancy in HER2 status, its evaluation by both IHC and SISH may be useful for detecting patients who would benefit from trastuzumab, and it would therefore help guide decision-making processes in administering treatment.

Background/Objectives: Brain metastasis (BM) is a rare form of distant metastasis with papillary thyroid cancer (PTC). Patients with BM of PTC carry a poor prognosis. The aim of this study was to contribute to the understanding of this disease by analyzing patients with BM of PTC. Materials & Methods: Between March 2003 and December 2013, the patient database was conducted to identify thyroid cancer patients treated. Among the 22,758 thyroid cancer patients, 14 (0.06 %) were identified to have metastasis to the brain during follow-up. The medical records of 14 patients with BM were retrospectively reviewed, focusing on the following: patient characteristics, synchronous or previous distant metastasis, treatments including whole brain radiotherapy (WBRT), stereotactic radiosurgery (SRS) and surgery, and characteristics on radiologic findings, time interval between first diagnosis of primary thyroid cancer and BM and survival after BM. Results: The mean age at initial diagnosis and BM were $50.9{\pm}15.8years$ and $61.3{\pm}12.7years$. The mean duration between initial diagnosis and BM was $10.4{\pm}7.9years$. Patients were treated with varied combinations of surgery, SRS and WBRT except 4 patients who had refused treatment. The median overall survival (OS) time after BM diagnosis was 10 months (range 1 - 19). Patients receiving treatment (WBRT and/or surgery, SRS) had a significant longer median OS of 16.5 months in comparison to 3.5 months for those treated without treatment. (p = 0.005) Conclusion: Patients who received aggressive treatment had a longer OS than those with only supportive care. Treatment such as surgery, SRS and WBRT should be considered in patients with BM.

Background: Survival rates after resection of advanced gastric cancer are extremely poor. An increasing number of patients with gastric carcinomas (GC) are therefore being treated with preoperative chemotherapy. We evaluated 36 month survival rate of GC patients that were treated by adding a neoadjuvant chemoradiotherapy before gastrostomy.Materials and Methods: Patients with stage II or III gastric adenocarcinomas were enrolled. The patients divided into two groups: (A) Neoadjuvant group that received concurrent chemoradiation before surgery (4500cGy of radiation at 180cGy per day plus chemotherapy with cisplatin and 5-fluorouracil, in the first and the end four days of radiotherapy). Resection was attempted 5 to 6 weeks after end of chemoradiotherapy. (B) Adjuvant group that received concurrent chemo-radiation after surgical resection. Results: Two (16.7%) patients out of 12 patients treated with neoadjuvant chemo-radiotherapy and 5 (38.5%) out of 13 in the surgery group survived after 36 months. These rates were not significantly different with per protocol and intention-to-treat analysis. The median survival time of patients in group A and B were 13.4 and 21.6 months, respectively, again not significantly different. Survival was significantly greater in patients with well differentiated adenocarcinoma in group B than in group A (p<0.004). Conclusions: According to this study we suggest surgery then chemoradiotherapy for patients with well differentiated gastric adenocarcinoma rather than other approaches. Additional studies with greater sample size and accurate matching relying on cancer molecular behavior are recommended.

Objective: To investigate the influence of offspring-related characteristics on the prevalence of depressive disorders among cancer patients and those who survived cancer for at least 45 years. Materials and Methods: Data were obtained from the Korean Longitudinal Study of Aging (KLoSA). To investigate the association between offspring and depressive disorder among cancer patients and survivors, we analyzed data from 292 cancer patients and survivors drawn from a total subject pool of 16,613 individuals at baseline. Results: According to our results, the odds ratio (OR) for subjects with five or more offspring developing depressive disorder was -0.794 (p-value: 0.039, SE: 0.329) compared with that of those with two offspring. In addition, the adjusted effect of the number of male and female offspring on the presence of depressive disorder showed that the OR for those with three or more female offspring for developing depressive disorder was -0.958 lower (SE: 0.305, p-value: 0.012) than it was for those with no female offspring. Conclusions: This article provides evidence for an association between offspring-related characteristics and depressive disorders among cancer patients and survivors. Therefore, offspring may be important contributors to the emotional status of cancer patients and survivors. Further study should precisely need to measure depressive disorders because of self-reported data.

Purpose: The purpose of this study was to identify the needs of hospice care in families of the hospitalized patients with terminal cancer. Method: The data were collected from April to July, 2008. The participants were 100 family caregivers of hospitalized terminal patients with cancer recruited from two general hospitals in 2 cities in Korea. Needs of hospice care were measured using the 'Needs Assessment Instrument for Hospice Care in Families of the Patients with Cancer'. Results: The mean of needs score was 76.6, which meant degree of the needs was very high. Among the categories of the needs, the mean of category 'emotional care' was the highest. There were significant differences in the needs of hospice care according to sex and type of present therapy. Conclusion: Health care providers in hospital and hospice facilities must assess the needs of families as well as the patients in order to meet their specific needs. Additionally, they need to have deeper understanding of the need of emotional care and to apply emotional care to hopice patients and their families.

Distress in patients with digestive cancers can considerably impact not only their treatment adherence but also their health-related quality of life. Early distress recognition in patients, appropriate interventions by the oncology team, or referral to mental health professionals, can enhance the treatment efficiency. This review aims to provide an overview of distress evaluation and its management in patients with cancer, specifically digestive cancers, and to address the psychological responses and distress that occur in those patients during treatment. Furthermore, the review will introduce possible psychological interventions for patients with digestive cancers who experience significant distress, depending on the duration and planning of the treatment.

Background: This study was conducted to determine levels of lipid peroxidation and antioxidant vitamin status in patients with oral cavity and oropharyngeal cancer. Methods: The study group consisted of a total number of 80 subjects between the age 40-68 years, 40 with clinically and histopathologically proved cases of oral cavity and oropharyngeal cancer and 40 normal healthy, age and sex matched volunteers as controls. Levels of lipid peroxidation products as malondialdehyde (MDA) and antioxidant vitamins as vitamin A and vitamin C were estimated and compared between the two groups. Results: There was a statistical significant difference in the mean MDA, plasma vitamin A and vitamin C in the oral and oropharyngeal cancer patients compared with the healthy controls (p<0.0001). Conclusions: Lipid peroxidation (MDA) is higher and plasma antioxidant vitamins like vitamin A and vitamin C were lower in oral cavity and oropharyngeal cancer patients than healthy controls.

Purpose: Studies focus on cancer control, prevention, or assessment of psychosocial problems and intervention methods. However, few studies exist concerning psychosocial problems, measuring tools for those problems, and interventions for cancer patients in Korea. One of the purposes of this study was to review studies in this area, to examine various psychosocial problems experienced by cancer patients. This is a crucial area to investigate, since psychosocial problems in turn negatively influence the patients' immune function, which speeds the progress of the disease. Another goal was to identify instruments used to measure psychosocial functioning and problems in cancer patients, to analyze their validity and reliability, with the aim to discover the best instruments. A final goal was to explore and compare the effects of psychosocial interventions, to determine the most effective practices. Method: Journal articles published since 1995 were searched from PubMed Data base, Google search engine, and published cancer-related studies, using search keywords "psychosocial function and intervention for the cancer patients"; whole articles of selected references were reviewed and analyzed. Result: Most common psychosocial problems were depression, fatigue, nausea, pain, distress, resulting in a low quality of life. The seven scales found in the literature to assess the psychosocial functioning were Center for Epidemiological Studies-Depression, State-Trait Anxiety Inventory, Symptom Checklist 90-R, Profile of Mood States, Psychosocial Adjustment to Illness Scale, Brief Symptom Inventory, and SF-36 HRQOL(Health Related Quality of Life). Social support interventions for cancer patients were effective in improving quality of life scores. Conclusion: It is necessary to apply support intervention strategies to help cancer patients in Korea. These strategies can help to reduce the effects of psychosocial symptoms, which in turn affect the development and control of cancer. Strategies developed in Western countries may need to be modified for use within Korea. Further studies are warranted to review the support intervention strategies that were being used to for cancer patients

The prognosis for pancreatic cancer patient is very poor. Patients with locally advanced disease have a median survival time of 8 to 12 months, and patients with distant metastases have significantly worse outcomes, with a median survival time of only 3 to 6 months. Approximately 30% of patients with pancreatic cancer present with locally advanced disease defined as unresectable pancreatic cancer without evidence of distant metastatic disease. Primary treatment options in locally advanced pancreatic cancer include chemotherapy and radiotherapy. Here, we reported a patient with locally advanced pancreatic cancer who does not want further chemotherapy because of chemotherapy induced nausea and vomiting. Irreversible electroporation was performed. Irreversible electroporation was well tolerated in this case, and may be a therapeutic modality for selected patients with locally advanced pancreatic cancer.
