Objective: Methylenetetrahydrofolate reductase (MTHFR) gene polymorphisms have been reported to be associated with pancreatic cancer, but the published studies had yielded inconsistent results.We therefore performed the present meta-analysis. Methods: A search of Google scholar, PubMed, Cochrane Library and CNKI databases before April 2012 was conducted to summarize associations of MTHFR polymorphisms with pancreatic cancer risk. Assessment was with odds ratios (ORs) and 95% confidence intervals (CIs). Publication bias were also calculated. Results: Four relative studies on MTHFR gene polymorphisms (C667T and A1298C) were involved in this meta-analysis. Overall, C667T(TT vs. CC : OR = 1.61, 95%CI = 0.78 - 3.34; TT vs. CT : OR = 1.41, 95%CI = 0.88-2.25; dominant model: OR = 0.68, 95%CI = 0.40-1.17; recessive model: OR = 0.82, 95%CI = 0.52-1.30) and A1298C(CC vs. AA:OR=1.01, 95%CI=0.47-2.17; CC vs. AC: OR=0.99,95%CI=0.46-2.14; dominant model: OR=1.01, 95%CI = 0.47-2.20; recessive model: OR = 1.01, 95%CI = 0.80-1.26) did not increase pancreatic cancer risk. Conclusion: This meta-analysis indicated that MTHFR polymorphisms (C667T and A1298C) were not associated with pancreatic cancer risk.

췌장암은 예후가 매우 불량한 암으로 수술적 절제술을 시행하여도 대부분의 경우 재발을 한다고 알려져 있다. 재발을 하는 경우 대개 항암화학요법을 시행하게 되나, 그 반응 또한 좋지 않은 것으로 알려져 있다. 간에 국소적으로 재발을 했을 경우 종양절제술을 시행하는 것에 대해서는 몇몇 보고가 있는 정도이며, 생존율을 향상시킬 수 있는지에 대해서는 연구가 거의 없는 상태이다. 본 증례는 유문보존 췌십이지장 절제술 시행 후 간에 국소적으로 재발한 췌장암에 대하여 gemcitabine 및 capecitabine과 oxaliplatin 병합 항암화학요법을 시행하였으나 크기가 증가하였고, 이에 종양절제술을 시행하였으며, 이후 장기생존을 보였던 경우로 매우 드문 증례를 경험하였기에 보고하는 바이다.

본 증례는 전이성 췌장암에서 연수막전이로 발현된 국내 첫 사례이다. 또한 급성뇌졸중 양상이 첫 증상으로 발현된 경우도 이전에 보고된 바가 없다. 향후 전이성 췌장암의 뇌전이 양상에 대해 좀 더 많은 증례를 통한 연구가 필요하며, 췌장암의 빈번한 연수막전이 기전에 대해서도 추가 연구가 필요하다.

Objective: This long-term case report details a case of pancreatic cancer with lung metastasis suppressed by integrative cancer medicine (IMT). Methods: A 64-year-old woman diagnosed with pancreatic cancer visited a Korean medicine hospital complaining about the side effects of chemotherapy for lung metastasis. She received IMT involving Korean traditional medicine and Western immunotherapy from May 2017 to June 2023. Tumor dimensions were assessed through computed tomography (CT) and positron-emission tomography/CT scans, while tumor markers and safety were monitored by laboratory tests. Results: IMT suppressed the progression of cancer, as observed by imaging and laboratory tests. The patient achieved 5-year survival, even after discontinuing chemotherapy. Conclusion: This case presents a potential therapeutic alternative for patients who are ineligible for chemotherapy or surgical interventions.

The purpose of this study is to investigate the apoptotic effect of Phellodendri Cortex water extract (PCWE) on pancreatic cancer cells and to find out the regulating mechanisms. Human-derived pancreatic cancer cell line, MIA PaCa-2 cells were treated by PCWE with various concentrations and the cytotoxicity was determined by MTT assay. The activation of Annexin V, DNA fragmentation, cell cycle arrest and caspase activation were observed to investigate the role of PCWE in pancreatic cancer cells. Also, to find out the regulating mechanisms, we examined the ROS production. The treatment of PCWE induced the cell death in both concentration and time dependent manner. The treatment of PCWE also increased the expression of Annexin V, DNA fragmentation, cell cycle arrest, and cleavage of caspase, which means cell-death PCWE induced was apoptosis but not necrosis. The ROS production was increased by PCWE treatment and the blockade of ROS inhibited the PCWE-induced cell death. These results could suggest that PCWE induced apoptosis via ROS release in pancreatic cancer cell.

This study investigated the cytotoxic effects and mechanism of action of asiatic acid in pancreatic cancer cell lines. First, we confirmed the cell viability of MIA PaCa-2 and PANC-1 cells after asiatic acid administration for 48 and 72 h. The viability of MIA PaCa-2 and PANC-1 cells decreased in a dose-dependent manner following asiatic acid administration. To investigate the underlying mechanism, we performed a terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay, annexin V assay, and western blotting. Asiatic acid induced apoptosis and autophagy through activation of AMP-activated protein kinase (AMPK) and inhibition of mammalian target of rapamycin (mTOR) in MIA PaCa-2 cells. Finally, the expression of miR-17 and miR-21, known as oncogenes in pancreatic cancer, was decreased by asiatic acid. These results indicate that asiatic acid has potential as a new therapeutic agent against pancreatic cancer.

Objectives : The purpose of this study is to report the effect of Korean medicine on the pancreatic carcinoma patient. Method : A patient was diagnosed as unresectable pancreatic carcinoma. She complained insomnia, abdominal pain, dyspepsia and sleep disturbance. She was treated by Korean medicine composed of acupuncture, herbal medication and wild ginseng pharmacopuncture. Results : All symptoms took a favorable turn after Korean medicine treatment. As treatment was performed, as intensity of pain, insomnia, dyspepsia and fatigue were decreased. Conclusion : This study suggests that Korean medicine treatment has effectiveness for improvement of cancer related symptoms of a pancreatic carcinoma patient. Consequently, the treatment is helpful in improving quality of life.

Pancreatic cancer is one of the most fatal cancers with a poor prognosis. Standard chemotherapies have proven largely ineffective because of their toxicity and the development of resistance. Therefore, there is an urgent need to develop novel therapies. In this study, we investigated the antitumor activity of MS-5, a naphthalene derivative, on BxPC-3, a human pancreatic cancer cell line. We observed that MS-5 was cytotoxic to BxPC-3 cells, as well as inhibited the growth of cells in a concentration- and time- dependent manner. Flow cytometry analysis revealed that the percentage of annexin V-positive cells increased after MS-5 treatment. We also observed cleavage of caspases and poly (ADP-ribose) polymerase, and downregulation of Bcl-xL protein. Flow cytometry analysis of intracellular levels of reactive oxygen species (ROS) and mitochondrial superoxide suggested that MS-5 induced the generation of mitochondrial superoxide while lowering the overall intracellular ROS levels. Thus, MS-5 may be potential candidate for pancreatic cancer treatment.

Objectives: To analyze underlying disease, fatality rate and the major causes of death of in-patients with malignant tumors in Sichuan Cancer Hospital. Methods: Clinical data of in-patients from 2002 to 2012 were retrospectively analyzed. Results: The top 10 tumors (82.0%of the total) of the malignant tumors of the in-patients were lung, cervical, esophagus, breast, colorectal, nasopharynx, liver and gastric cancers, lymphomas and ovarian cancers. The overall fatality rate was 2.7% during these eleven years, 3.4% and 2.0% for male and females, respectively with statistical significance for the difference (${\chi}^2$=164.737, P<0.001). The top 10 death causes were lung cancer, liver cancer, colorectal cancer, esophagus cancer, gastric cancer, lymphoma, breast cancer, pancreatic cancer, ovarian cancer and nasopharynx cancer. In-patients with pancreatic cancer had the highest fatality rate (9.6%). There were different ranks of death causes in different sex groups and age groups. Conclusion: Prevention and control work of cancer should be enhanced not only for cancers with high incidence such as lung cancer, esophageal cancer but also for the cancers which have low incidence but high fatality rate, such as pancreatic cancer and gallbladder cancer, which would help to improve the survival rate and quality of life of cancer patients in the future.

Gemcitabine demonstrated modest activity in locally advanced and metastatic pancreatic cancer with difficulty early diagnosis and poor prognisis. The purpose of this study was to evaluate the efficacy and toxicity of gemcitabine and 5-fluorouracil(GF) combination theraphy and epirubicin. cisplatin. and 5-fluorouracil(ECF) combination theraphy for the patients with locally advanced or metaststic pancreatic cancer. Between January 1996 and December 2001. (omitted)
