  • Objective: Standard cancer therapy prolongs survival, but can be detrimental to the quality of life, compromise the immune system, and leave residual disease that can cause recurrence years or decades in the future. Tumor dormancy therapy is a novel therapeutic approach that may improve these shortcomings, promote quality of life, and prolong survival. The aim of this study was to analyze studies on dormancy therapy, especially studies using traditional Oriental herbal medicine, so as to evaluate the efficacy of dormancy therapy with traditional oriental herbal medicine. Methods: We conducted a systematic literature review using Scientific and Technical Information Integration Services (NDSL), PubMed, and RISS. We searched for clinical reports, papers, and books related to tumor metastasis, recurrence, immunotherapy, tumor dormancy, and traditional oriental herbal medicine with anticancer effects. Seventy-nine (79) experimental and clinical articles in both Korean and English were reviewed. This study was conducted from March 1, 2012 to May 31, 2012. Results: This approach, Tumor dormancy therapy, rather than seeking to remove the tumor, includes combination of low-dose chemotherapy, immunotherapy, immunosurveillance, and other methods to stabilize tumor growth and to enhance the host is immunity against disseminated tumor cells and thus to manage cancer as a chronic disease while maintaining quality of life. In particular, integrative use of Oriental herbal medicine has been shown to induce or maintain tumor dormancy, increase the effectiveness of conventional chemotherapy, improve quality of life, and prolong survival. Conclusion: Tumor dormancy therapy is a promising novel therapeutic approach that may be especially effective with Oriental herbal medicine. Further research is needed to determine its potential mechanisms and therapeutic applications.

  • Background: The greatest threats to the lives of cancer patients consist of both complications due to metastasis and the recurrence of original cancer. However, the existing forms of chemotherapy do not prevent these adverse events adequately because they suppress the patients' immune systems. A new methodology is required. Aim: To provide further validation for cancer immunotherapy (involving the use of traditional oriental herbal medicine). Method: Related articles, in both Korean and English were reviewed. Results: Cancer immunotherapy involving the use of traditional oriental herbal medicine can create inhospitable conditions for cancer cells and strengthen patients' immunological functioning. These effects are a demonstration of the principles of "strengthening healthy qi (扶正)" and "eliminating pathogens (祛邪)". As a result, immunotherapy protects against metastasis and original cancer recurrence by preventing the growth of cancer cells. This is very similar to the concept of a cancer dormancy therapy. Conclusion: It is strongly urged by the authors that more advanced studies be carried out on this promising therapy in the future in order to improve patients' quality of life and increase their survival time.

  • Objective: This study investigated the trends in pancreatic cancer research on Korean medicine in order to establish a direction for further study. Methods: Pancreatic cancer research on Korean medicine was reviewed using databases such as OASIS, KoreanTK, KISS, RISS, KISTI, and NDSL. The search terms were "pancreatic cancer" "Korean medicine," and "herbal medicine." There was no restriction on publication dates, and the reviewed studies were analyzed according to the type of research. Results: Nineteen studies were reviewed. The numbers and types of research were as follows: 9 clinical studies including case reports, 2 review studies, and 8 in vitro studies; there was no in vivo study. Among the clinical research were 3 descriptive studies and 6 case reports. The baseline characteristics and quality of life of pancreatic cancer patients were analyzed in the descriptive studies. In the case reports, interventions such as herbal medicine, pharmacopuncture, and acupuncture were used. Research articles on the review of pancreatic cancer were titled "Preliminary Study for Development of Korean Medicine Clinical Practice Guideline for Pancreatic Cancer" and "Systemic Review on the Tumor Dormancy Therapy." Cell lines such as PANC-1, MIA PaCa-2, and AsPC-1 were used for in vitro studies. These studies have reported decreased cell viability, induced apoptosis, and changes in cancer-related gene expression. Conclusion: Through this review, we found that using Korean medicine for treating pancreatic cancer is applicable. However, due to overall limited the number of study, the benefit of Korean medicine for pancreatic cancer may be substantiated to a limited degree. Better methodological quality and large controlled trials are expected to further quantify the therapeutic effect of Korean medicine.

  • The present study investigated the plant growth characteristics, dormancy breaking, yield, and biological activity properties (contents of flavonoid and phenolic compounds, nitrite scavenging activity, and the survival rate of lung cancer) of four asparagus cultivars. It aimed to examine selection possibilities for high efficacy cultivar to promote biological activity in asparagus cultivation in South Korea. The results showed that the number of asparagus buds and root fresh and dry weight of 'Jersey Giant', 'Jersey Supreme', and 'NJ953' were higher than those of 'UC157' cultivar, and there were no differences in the number of roots. The dormancy breaking period of 'Jersey Supreme' was prolonged compared to the other cultivars. 'Jersey Giant' and 'NJ953' had more total spears, and greater spear diameter, and yield than other cultivars. Total flavonoid content was unaffected by cultivar and was higher in ethanol extraction than in hot water extraction. Total phenolic compound content was the lowest in 'NJ953' for both hot water and ethanol extracts, whereas in the ethanol extraction, 'UC157' had the highest, with $39.23mg{\cdot}L^{-1}$. 'Jersey Giant', 'Jersey Supreme', and 'NJ953' all showed greater than 70% nitrite scavenging activity. In the case of ethanol extraction, the survival rates of lung cancer in extracts from 'Jersey Giant', 'Jersey Supreme', and 'UC157' were lower than 'NJ 953' cultivar, regardless of extraction concentration. The survival rate of lung cancer was lower in hot water extraction than in ethanol extraction, so that the consumption of asparagus is also expected to be helpful in preventing lung cancer. The growth characteristics and biological activity effects of edible asparagus that were identified in the present study are expected to be useful in selection of high efficacy cultivars for biological activity and utilization.

  • Background: : In 2012, the breast cancer estimate worldwide stood at 1.67 million new cases, these accounting for 25% of all types of cancer diagnosed in women. For 2014, 57,120 new cases are expected, with a risk estimated at 56.1 cases for every 100,000 women. The objective of this study was to analyze the satisfaction regarding the use of external breast prostheses by women undergoing mastectomy. Materials and Methods: This cross-sectional study was conducted with 76 women who used an external breast prosthesis (EBP), registered in the services of the Cuiaba Center for Comprehensive Rehabilitation, Mato Grosso, Brazil, from 2009 to 2012. Data were collected from the records of women who had requested the opening of a process of external breast prosthesis concession. Results: Satisfaction with the EBP was identified in 56.6% of the women. Those satisfied with the EBP reported that its weight was not annoying (p<0.01). Although the women felt body sensations of stitches, pains, pulling, dormancy and phantom limb, they are satisfied with the EBP. The variable related to the displacement of the breast prosthesis during activity of everyday life has demonstrated that even though the women have reported the possibility of displacements, they are satisfied with the EBP. The satisfaction with the use of external breast prosthesis did not affect the sexuality of the women with mastectomy. Conclusions: Learning the specificities of the EBP, taking into consideration the satisfaction of its use, allows the rehabilitation team, by listening to their clientele more attentively, following up this woman throughout her life journey, supporting and guiding the best way of use, with an eye to her personal, emotional and social life, as well as to her self-esteem.
