  • Neoadjuvant chemotherapy for resectable esophageal carcinoma has been a focus of study, but no agreement has been reached on clinical randomized controlled trials and relevant systematic evaluation. The purpose of this study was to perform a meta-analysis on published randomized controlled trials (RCTs) that compared neoadjuvant chemotherapy and surgery with surgery alone for resectable esophageal carcinoma. Medline and manual searches was conducted in PubMed, ASCO (American Society of Clinical Oncology) meeting summary, Embase, the Cochrane Library (up to October 2010), Chinese Biomedical Literature Database, China National Knowledge Infrastructure, VIP Database, Wanfang Database. The selection contents were to identify all published and unpublished RCTs that compared neoadjuvant chemotherapy and surgery with surgery alone for resectable esophageal carcinoma. Sixteen RCTs which included 2,594 patients were selected. The risk ratio (RR) (95% confidence interval [CI]; P value), expressed as neoadjuvant chemotherapy and surgery versus surgery alone (treatment versus control), was 1.02 (0.95, 1.10; P=0.54) for 1-year survival, 1.29 (1.13, 1.47; P=0.0001) for 3-year survival, 1.31 (1.13, 1.51; P=0.0003) for 5-year survival, 1.00 (0.95, 1.04; P= 0.85) for rate of resection and 0.89 (0.64, 1.23; P=0.48) for operative mortality. The results showed that neoadjuvant chemotherapy for resectable esophageal carcinoma can raise the overall survival rate of patients with esophageal carcinoma, but it does not affect treatment-related mortality.

  • Objectives : Cancer incidence is increasing in all countries and chemotherapy-induced peripheral neuropathy (CIPN) in patients undergoing chemotherapeutic agents have been a clinically serious problems. So far therapeutic options for CIPN patients are limited and no confirmed methods have yet been established for dealing with peripheral neuropathy. Therefore this review is to provide an evidence-based summary of oriental medicine and CAM (complementary and alternative medicine) neuroprotective and treatment therapies which have gone through clinical trials. Methods : An overview of the domestic and international papers of adult clinical trials relating management of only CIPN symptoms through 1990 to present were searched by electronic databases. Search key words were chemotherapy-induced neurotoxicity, chemotherapy-induced peripheral neuropathy, chemotherapy toxicity & herb, chemotherapy toxicity & acupuncture, chemotherapy toxicity & CAM. Only English and Korean written papers were reviewed. Total 25 papers were reviewed in this study, 18 papers were retrieved by electronic search. Results : Clinical studies of managing CIPN were rare, two acupuncture clinical studies and four herb medicinal studies were found. Rest of 19 papers were about other CAM clinical studies. Total 25 papers were analyzed, and all interventions were focused on their pain control efficacy. Other 24 trials of potential therapies except one proved to be effective for CIPN, however some described to be inadequate positive or sufficient negative. Conclusions : As most of the studies were pilot studies, interventions for the prevention and treatment of CIPN have to go through prospective confirmatory studies, such as larger scale randomized, double-blinded, placebo controlled clinical trials must be done for the safe and effective use of proposed therapies. Also standard measurement scales have to be developed for the better clinical study of CIPN.

  • Colorectal cancer is one of the most prevalent diseases all over the world. Early screening and start of chemotherapy is effective in decreasing mortality. This type of cancer can be controlled to some extent via a healthy diet rich in fruit and vegetables. Ginseng is a plant which has been consumed as a herbal medicine for thousands of years in Asian countries. Several in vitro and in vivo studies have shown that this plant not only reduces the incidence of colorectal cancer, but also improves patient's status by enhancing the effects of chemotherapy drugs. However, further studies are needed to prove this relationship. We briefly review ginseng and its components such as ginsenosides reported anticancer effects and their mechanisms of action. Understanding these relationships may produce insights into chemical and pharmacological approaches for enhancing the chemo preventive effects of ginsenosides and for developing novel anticancer agents.

  • Objectives: The objective of the present study was to compare prognosis of patients with gastric or colorectal cancer according to places where they received surgeries. Methods: The cancer patients underwent surgeries in sampled hospitals located in Daegu were matched 1:1 to the patients who visited sampled hospitals in Seoul using propensity score method. After the occurrences of death were examined, Kaplan-Meier method was used for survival analysis and the log-rank test was performed to compare the survival curves. Results: A total of six out of 291 gastric cancer patients who had surgeries in Daegu died (2.1%) and ten deaths (3.4%) occurred from patients went Seoul hospitals. Out of 84 gastric cancer patients who had chemotherapy after surgeries in Daegu, 13 (15.5%) patients died while 18 (21.4%) deaths occurred among patients underwent surgeries in Seoul. Six deaths (6.9%) out of 87 colorectal cancer patients who had surgeries in Daegu were reported. Five patients (5.7%) died among the patients underwent surgeries in Seoul. Among the colorectal cancer patients with chemotherapy after surgeries, 13 patients (12.4%) who visited hospitals in Daegu and 14 (13.3%) patients who used medical centers in Seoul died. There were no significant differences according to places where patients used medical services. Conclusions: The result of this study is expected to be used as basic data for policy making to resolve centralization problem of cancer patients and to help patients to make rational choices in selection of medical centers.

  • Background & Objectives : Colorectal Cancer is 10% of all cancer incidence and the motality from colorectal cancer is nearly 450,000 a year. Since chemopreventive agents from Herbal medicine is hot issue recently, to prove antitumor effecicacy of Rhus vernifciflua STOKES decoction(Chijong-tang), clinical study was carried out. Here we report two patients with colorectal cancer of stage IV. One is colorectal cancer patient with liver, lung metastases underwent operation, chemotherapy. The other patient with liver metastasis underwent chemotherapy. All of two patients acquired tolerance. Methods : One patient visited Hana oriental medicine Clinic in 2010 and was treated using Chijong-tang for 17 months at Hana Oriental Clinic. The other patient visited Hana oriental medicine Clinic in 2011 and was treated using Chijong-tang for 5 months at Hana Oriental Clinic. Results : Chijong-tang showed no side effect, no more tolerance during its treatment with chemotherapy and tumor size was retarded based on CT scanning. Overall, this case report suggests that Rhus vernifciflua STOKES can be a potent cancer preventive agents for colorectal cancer but it is still required to verify the scientific and clinical evidences for Rhus vernifciflua STOKES decoction (Chijong-tang).

  • Background: Breast cancer is a treatable disease, but some women reject conventional treatment in favor of unproven "alternative therapies," which may have serious implications for their survival. Therefore, a process is needed to lead them to more appropriate treatment choices. Case presentation: Here, we present the case of a 51-year-old Korean female diagnosed with early-stage breast cancer (stage IIB, T2N1M0) in Nov. 2015. She refused a standard surgical resection together with chemotherapy and opted instead for moxibustion by nonmedical personnel. Consequently, her preference for alternative therapy without conventional treatment exacerbated her disease. Just a little over a year later, integrative cancer treatment, including chemotherapy based on histological founding, and complementary treatment, comprised of acupuncture, moxibustion, and herbal medicine, were administered for 5 months. Finally, she successfully underwent modified radical mastectomy showing a pathological complete response. She received only adjuvant chemotherapy without any alternative medicine afterwards, and she maintained a good status without recurrence. Conclusion: In the case of breast cancer patients who are resistant to surgery and chemotherapy, integrative therapy considering adverse effects from conventional treatment should be preferred to bitter opposition to alternative medicine.

  • This study was performed for the comparison of the therapeutic efficiency between 6-month (2HERZ/4HER) and 9-month (9HER) short-course chemotherapy under the programe conditions for pulmonary tuberculosis in terms of sputum AFB negative conversion rate, remedial interruption rate and cost effectiveness analysis. Two hundreds and ninty three patients treated with 9HER and 641 treated with 2HERZ/4HER had been discharged from 22 health centers in Seoul from May 1, 1993 to April 30, 1994. Seven hundreds and seventeen was subsequently analysed excluding 217 patients due to remedial interruption. The results : 1. Bacteriological negative conversion rate in 9HER regimen and 2HERZ/4HER regimen was 97.8% and 96.4% respectively(p>0.05). But the early treatment period, negative conversion rate in 2HERZ/4HER regimen was very higher than in 9HER regimen(p<0.01). 2. Remedial interruption rate for 9HER regimen and 2HERZ/4HER regimen was 34.1% and 13.6% respectively. The primary reason for the interruption was transfering to other clinics and this interruption was high within 3months. 3. Cost effectiveness for 2HERZ/4HER regimen was higher than 9HER regimen. The difference cost effectiveness ratio was 2.33 at the first sputum test and 1.69 at the last sputum test.

  • The membrane fatty acid composition of tumor cell can be modified either in cell by altering the lipid composition of the medium of during growth in animals by changing the dietaty fat composition. These modifications are associated with changes in membrane physical properties and certain cellular functions, including carrier-mediated transport and enzyme contained within the membrane. Such effects influence the transport of nutrients and chemotherapeutic agents in cancer cells .Fatty acid modification also can enhance the sensitivity of the neoplastic cell to chemotherapy. The alteration in plasma membrane composition will be affected through dietary supplementations and the potential value to cancer patients could be a better understanding of the effects of diet on responsiveness of neoplasms to chemotherapy, i.e. cancer patients' chances for a "cure" can be improved by diet changes prior to treatment.

  • One of the most common side effects of chemotherapeutic agents is chemotherapy-induced peripheral neuropathy (CIPN). The occurrence of CIPN is increasing as the survival rate of patients with cancer improves and the cumulative dose or duration of neurotoxic drugs increases. Approximately 30-40% of patients receiving neurologically toxic drugs experience CIPN, which eventually increases the burden of medical expenses. However, preventive measures against CIPN have not yet been established. Clinical trials have tested various drugs for the management of neuropathic pain, but only duloxetine has shown any significant effect. Further studies should evaluate nonpharmaceutical treatments, such as exercise.
