Purpose: In this study, the effects of laughter therapy on levels of depression, quality of life, resilience and immune responses in breast cancer survivors were examined. Methods: A quasi-experimental nonequivalent control group, pretest-posttest design was used. Participants (n=37) included breast cancer survivors who finished chemotheraphy and radiation therapy: 16 in the experiment group and 21 in the control group. Data were collected from August to November 2009. The experimental group participated in laughter therapy eight times, twice a week for 60 min per session. Questionnaires were used to me-asure pretest and posttest levels of depression, quality of life and resilience. A blood test was used to analyze changes in Total T cell, T helper, T suppressor, Th/Ts ratio, Total B cell, T cell/B cell ratio and NK cell for immune responses. Results: The results showed that laughter therapy was effective in increasing the quality of life and resilience in breast cancer survivors. but depression and immune responses did not differ significantly between the groups. Conclusion: The results of the study indicate that laughter therapy may be an effective nursing intervention to improve quality of life and resilience in breast cancer survivors.

Cancer treatment remains a serious problem worldwide. Analysis of the relationship between cancer cells and normal cells reveals that these two share characteristics in contradiction, thus could be analyzed by using contradictory principles. Under the theory of contradictory principles, induction of a dormant state or reversal of cancer cells is an important treatment strategy beyond traditional cytotoxic therapy. Normal cells are also the targets and under the influence of anti-cancer treatments and should be considered during therapy. Findings based on crosstalk between these two cell types may offer opportunities for the development of new biomarkers and therapies.

Background: Several studies have previously focused on associations between the (GT)n repeat polymorphism of the heme oxygenase-1 (HO-1) gene promoter region and risk of cancers, but results are complex. We conducted the present meta-analysis to integrate relevant findings and evaluate the association between HO-1(GT)n repeat polymorphism and cancer susceptibility. Materials and Methods: Published literature was retrieved from the PubMed/MEDLINE, EMBASE and ISI Web of Science databases before November 2013. For all alleles and genogypes, odds ratios were pooled to assess the strength of the associations using either fixed-effects or random-effects models according to heterogeneity. Subgroup analysis was conducted according to ethnicity and histopathology. Results: A total of 10 studies involving 2,367 cases and 2,870 controls were identified. The results showed there was no association between HO-1 (GT)n repeat polymorphism and the cancer risk both at the allelic and genotypic level. However, in the stratified analysis, we observed an increased risk of squamous cell carcinoma in persons carrying the LL genotype and the LL+LS genotype as compared with those carrying the SS genotype. When the LS and SS genotypes were combined, the odds ratio for squamous cell carcinoma in LL-genotype carriers, were also significantly increased. No publication bias was observed. Conclusions: The LL genotype and L-allele carrying genotypes (LL+LS) of HO-1 (GT)n repeat polymorphism are potential genetic factors for developing squamous cell carcinoma. More large and well-designed studies are required for further validations.

Objectives: This review aims to investigate clinical studies related to bee venom pharmacopuncture for cancer patients and to analyze the research trend for further study. Methods: We searched for clinical studies using bee venom pharmacopuncture therapy on patients with cancer through the electronic databases including Pubmed, Cochrane library, OASIS, KISS, NDSL, and KMBASE. There was no restriction on language and publication date, and after selection/exclusion process, the study design, target disease, intervention details including acupoints, treatment frequency and period, outcomes, study results and adverse events were extracted. Results: Thirteen clinical studies were finally selected. There were a randomized controlled trial RCT about the effect of sweet bee venom pharmacopuncture on cancer-related pain, and three case series about chemotherapy-induced peripheral neuropathy. In case reports, there were nine studies about oligodendroglioma, plexiform neurofibroma, breast cancer, prostate cancer, lung cancer, urachal adenocarcinoma, malignant melanoma, and atypical squamous cells of undetermined significance. The bee venom therapy affected the improvement of outcomes such as symptoms, quality of life, tumor response, and lab findings. Conclusions: The present study found that bee venom therapy is applicable to the treatment of cancer patients, and showed some effect on various symptoms. However, due to insufficient number and quality of studies, well designed and high-quality clinical trials are necessary to confirm the effectiveness and safety of bee venom pharmacopuncture therapy in patients with cancer.

The purpose of this study was to determine if international guidelines differ in their recommendations concerning additive therapy for advanced, but potentially curable, gastric cancer. A systematic search of the English and German literature was conducted in the databases Medline, Cochrane Database, Embase, and PubMed. The search terms used were 'guidelines gastric cancer,' 'guidelines stomach cancer,' and 'Leitlinien Magenkarzinom.' Six different guidelines published after January 1, 2010, in which the tumors were classified according to the seventh edition of the TNM system (2010), were identified. Although the examined guidelines were based on the same study results, their recommendations concerning accompanying therapy for gastric cancer differ considerably. While perioperative chemotherapy is recommended in Germany, Great Britain, and large parts of Europe, postoperative adjuvant radiochemotherapy or perioperative chemotherapy is recommended in the USA and Canada. In Japan, postoperative adjuvant chemotherapy is recommended. The results of identical studies were interpreted differently in different countries. Since considerable effort is required for each country to separately test relevant studies for their validity and suitability, an international cooperation could simplify the creation of a common basis for guidelines and contribute to improved comparability of international guidelines.

Intraoperative Radiation therapy (IORT) is a cancer treatment modality in which resectable masses or organs are removed surgically and residual cancer calls are sterilized by irradiation with a single massive dose during while patient is still anesthetized. Because it is possible that the turner mass can be visualized directly at the time of surgical exploration, tumor volume can be determined more precisely and at the same tin e sensitive adjacent structures can be pulled aside from the irradiation. With these theoretical advantages as compare to conventional external irradiation, IORT can improve the therapeutic ratio of tumor control to normal tissue injury. Yonsei cancer center initiated a pilot study of multidisciplinary IORT program in february of 1986 for the fist attempt in Korea. IORT Was performed in 7 patients with stomach cancer by using existing NELAC-1018 Linear Accelerator treatment room as a surgical suite. IOTR team included department of surgery, Department of Anethesiology, Department of Clinical pathology, operating room nursing personal and Department of radiation oncology.

Breast cancer is the most common in women worldwide, with some 5-10% of all cases due to inherited mutations of BRCA1 and BRCA2 genes. Obesity, hormone therapy and use of alcohol are possible causes and over-expression of leptin in adipose tissue may also play a role. Normally surgery, radiation therapy and chemotherapy allow a good prognosis where screening measures are in place. New hope in treatment measures include adjuvant therapy, neoadjuvant therapy, and introduction of mono-clonal antibodies and enzyme inhibitors.

전립선암의 방사선치료 시 사용되는 세기조절방사선치료와 부피적회전방사선치료시 발생하는 광중성자선량을 측정하여, 암 발생률을 평가하며 기초자료를 제공하고자 하였다. Rando phantom에 중성자 측정용 광자극발광선량계를 복부와 갑상선에 위치시킨 상태에서 발생하는 광중성자선량을 측정하였다. 연구결과 세기조절방사선치료(7 portal)가 부피적회전방사선치료보다 복부와 갑상선 위치에서 모두 높게 측정되었다. ICRP 103의 명목위험계수를 이용하여 암 발생확률을 평가하였을 때, 세기조절방사선치료시 대장과 갑상선의 피폭으로 인한 암발생확률은 1,000명 당 9.9명 이었으며, 부피적회전방사선치료시는 1,000명 당 3.5명이었다. ALARA(As low as reasonably archievable)원칙에 의거하여 방사선치료계획 수립에 있어서 정상장기들의 피폭선량의 최소화를 위한 가이드라인이 되리라 사료된다.

우리는 최근에 PRC1 프로모터가 유방암 유전자치료를 위하여 전사 표적이 된 유전자의 발현을 조절할 수 있는 후보 프로모터임을 보고하였다. 우리는 본 실험에서 PRC1이 폐암유전자 치료에서도 적용이 가능한지 조사하였다. 특정 프로모터가 루시퍼라제 유전자와 연결된 플라스미드를 이용한 형질전환 assay에서 PRC1 프로모터는 정상폐세포주에서는 활성을 보이지 않으나 폐암세포주에선 약 30 배의 활성을 보였다. 이는 이미 암특이적인 발현으로 알려진 BIRC5 (survivin) 프로모터와 유사한 결과였다. 또한, 바이러스 벡터를 이용한 실험에서 PRC1은 CMV 프로모터에 비해 아데노부속바이러스에서 약 75%, 아데노바이러스에서 약 66%의활성을 보였다. 이와 대조적으로, PRC1 프로모터를 함유한 이 들 두 종류의 바이러스는 정상 폐세포에서는 20%정도의 낮은 활성을 보였다. 흥미롭게도, 인간 폐종양세포를 이식한 생쥐모델을 사용한 결과에서는 PRC1 프로모터가 CMV 프로모터와 비슷한 생체 활성을 보였다. 종합하면, 이상의 결과는 PRC1이 폐암 유전자치료를 위한 전사표적 유전자의 발현을 위한 프로모터로 사용 가능함을 암시한다.
