  • Among the promising cancer therapy is targeting of the drug to tumor cells via receptor specific ligands. CR2945, $\beta$-2-( [2-(8-azaspiro [4.5] dec-8-ylcarbony!)-4.6-dimethylphenyl]amino-2-oxoethyl] -(R)-1-naphthalenepropanoic acid. is known to have an inhibitory effect on a gastrin receptor of colorectal cancer cells. As the human pancreatic cancer cells (BxPC-3) express gastrin receptors. interruption of binding of gastrin with gastrin receptor of human pancreatic cancer cells by CR2945 inhibits the growth of human pancreatic cancer cells.

  • Pulmonary tumor thrombotic microangiopathy (PTTM) is a rare but fatal complication of cancer and causes pulmonary hypertension and acute/subacute right heart failure. PTTM is most commonly associated with gastric cancer and more rarely associated with pancreatic cancer. We report a case of progressive right heart failure associated with clinically diagnosed pancreatic cancer, suggesting PTTM.

  • Pancreatic tumors in children are relatively rare, and their prognosis differs from that in adults. The purpose of this study is to examine the clinical characteristics, treatment, and prognosis for children with pancreatic tumors. We retrospectively reviewed the medical records of children under 15 years of age with pancreatic tumors who were treated surgically at Asan Medical Center between January 1992 and November 2009. There were 16 patients, fourteen of whom were pathologically diagnosed with solid pseudopapillary tumor. The other two patients were diagnosed with pancreatoblastoma and acinar cell carcinoma, respectively. Six patients of the 16 patients (38 %) were male, and there was a male-to-female ratio of 1:1.6. The initial presentations were upper abdominal pain in eight patients (50 %), palpable abdominal mass in three, and vomiting in one. Four patients were diagnosed incidentally. Six patients' tumors were located in the pancreatic head, six in the pancreatic body, and four in the pancreatic tail, respectively. The surgical procedures performed included distal pancreatectomy (n=7, 44 %), median segmentectomy (n=3), enucleation (n=3), pancreaticoduodenectomy (n=2), and pylorus-preserving pancreaticoduodenectomy (n=1). Three patients underwent laparoscopic surgery. The median tumor size was 6.5 cm (1.8~20 cm). Early surgical complications included pancreatic fistula (n=4), bile leakage (n=1), and delayed gastric emptying (n=1). A late complication in one patient was diabetes. The median follow-up period was five years and four months, and all patients survived without recurrence. While pancreatic tumors in adults have a poor prognosis, pancreatic tumors of childhood are usually curative with complete resection and thus have a favorable prognosis.

  • Background: Perineural invasion (PNI) has been reported as one of the sources of locoregional recurrence in resected pancreatic cancer (PC). However the impact of PNI in resected pancreatic cancer remains controversial. The purpose of this study was to determine the association between PNI status and clinical outcomes. Methods: Publications were identified which assessed prognostic significance of PNI status in resected pancreatic cancer up to February 2013. A meta-analysis was performed to clarify the association between PNI status and clinical outcomes. Results: A total of 21 studies met the inclusion criteria, covering 4,459 cases. Analysis of these data showed that intrapancreatic PNI was correlated with reduced overall survival only in resected pancreatic ductal adenocarcinoma (PDAC) patients (HR=1.982, 95%CI: 1.526-2.574, p=0.000). Extrapancreatic PNI was correlated with reduced overall survival in all resected pancreatic cancer patients (HR=1.748, 95%CI: 1.372-2.228, p=0.000). Moreover, intrapancreatic PNI status may be associated with tumor recurrence in all resected pancreatic cancer patients (HR=2.714, 95%CI: 1.885-3.906, p=0.000). Conclusion: PNI was an independent and poor prognostic factor in resected PDAC patients. Moreover, intrapancreatic PNI status may be associated with tumor recurrence.

  • A 67-year-old male was admitted due to abdominal pain. Abdominal CT scan performed in a local clinic showed about 2 cm sized pancreatic tail mass with extensive liver and multiple regional lymph node metastasis. Histology of liver biopsy revealed poorly differentiated adenocarcinoma. He underwent chemotherapy with gemcitabine and erlotinib for 5 cycles followed by 8 cycles of second line chemotherapy with 5-fluorouracil and cisplatin. At 12 months after diagnosis, follow-up abdominal CT scan revealed marked reduction of tumor mass in the liver and pancreas with small residual tumor. After one month of last chemotherapy, he complained radiating pain along left leg. Blood chemistry revealed isolated elevation of alkaline phosphatase (ALP) and multiple bone metastasis were demonstrated in bone scan. Palliative radiation therapy to pelvic bone was performed for the relief of bone pain. The prognosis of advanced pancreatic cancer is extremely poor. We report late occurrence of multiple bone metastasis in a patient with well controlled advanced pancreatic cancer with chemotherapy.

  • Many cancers arise from sites of chronic inflammation, which creates an inflammatory microenvironment surrounding the tumor. Inflammatory substances secreted by cells in the inflammatory environment can induce the proliferation and survival of cancer cells, thereby promoting cancer metastasis and angiogenesis. Therefore, it is important to identify the role of inflammatory factors in cancer progression. This review summarizes the signaling pathways and roles of C-reactive protein (CRP) in various cancer types, including breast, liver, renal, and pancreatic cancer, and the tumor microenvironment. Mounting evidence suggests the role of CRP in breast cancer, particularly in triple-negative breast cancer (TNBC), which is typically associated with a worse prognosis. Increased CRP in the inflammatory environment contributes to enhanced invasiveness and tumor formation in TNBC cells. CRP promotes endothelial cell formation and angiogenesis and contributes to the initiation and progression of atherosclerosis. In pancreatic and kidney cancers, CRP contributes to tumor progression. In liver cancer, CRP regulates inflammatory responses and lipid metabolism. CRP modulates the activity of various signaling molecules in macrophages and monocytes present in the tumor microenvironment, contributing to tumor development, the immune response, and inflammation. In the present review, we overviewed the role of CRP signaling pathways and the association between inflammation and cancer in various types of cancer. Identifying the interactions between CRP signaling pathways and other inflammatory mediators in cancer progression is crucial for understanding the complex relationship between inflammation and cancer.

  • Objective: The purpose of this study is to report effects and potential of Integrative Cancer Treatment (ICT) on metastatic pancreatic cancer patient. Methods: A 79-year-old pancreatic cancer patient diagnosed with metastasis on liver visited the Daejeon Korean medicine hospital of Daejeon university East West Cancer Center (EWCC) on May 2021. The patient has been received chemotherapy (gemcitabine plus abraxane) and concurrently treated with ICT since May 2021. The clinical outcomes were measured by computed tomography, laboratory findings including tumor markers (CEA, CA19-9) and numeric rating scales (NRS). Laboratory analysis and National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE), version 5.0 were used to evaluate the safety of ICT. Results: After treatment, constipation was relieved from NRS 5-6 to 2, both leg numbness was improved from NRS 9 to 2. Tumor size was generally decreased accompanying by reducing the levels of tumor markers. There were no severe adverse events induced by ICT based on NCI CTCAE version 5.0. Conclusion: This case study suggests that ICT in combination with chemotherapy may help in the treatment of patients with metastatic pancreatic cancer.

  • The solid pseudopapillary epithelial neoplasm (SPEN) of the pancreas is an uncommon tumor that accounts for approximately 1%-2% of exocrine pancreatic neoplasms. It predominantly affects female in their second and third decades of life. In this case report, we present a clinical scenario of a 21-year-old pregnant woman who incidentally discovered a solid cystic lesion in her pancreas, exhibiting features suggestive of SPEN. The patient underwent surgery during the second trimester. Management of pregnant females with SPEN poses challenges due to the absence of definitive treatment guidelines, particularly in determining the ideal timing for surgical intervention. Notably, during pregnancy, the presence of a small SPEN does not necessarily require immediate resection. However, if the tumor is of significant size, it can give rise to complications such as tumor rupture, multivisceral resection, recurrence, spontaneous abortion, intrauterine growth restriction, or premature delivery if not addressed. In the existing literature, a common finding is that approximately two-thirds of pregnant females with SPEN underwent surgery in the second trimester, often without complications for the mother or fetus. All these tumors were larger than 8 cm. The decision to operate before or after birth can be individualized based on team discussion. However, delay in surgery may lead to larger tumors and higher risks like bleeding, rupture, multivisceral resection, and recurrence. Therefore, second-trimester surgery seems safer, and lessens dangers, emergency surgery, and tumor recurrence.

  • About 80% of all pancreatic cancer patients suffer from a wasting syndrome defined as the cancer cachexia characterized by abnormally low weight, weakness, and loss of skeletal muscle mass, which directly impacts physical activity, quality of life and overall survival. Over the past decades, we have gained new insights into the underlying mechanism of cachexia associated with pancreatic cancer. The aim of this review was to explore recent findings about cancer cachexia pathophysiology and describe the current pharmacologic approach. Pancreatic cancer cachexia is a multifactorial syndrome mediated by mechanical factors, inflammatory cytokines, neuropeptides, hormones and tumor-derived factors. The treatment of cancer cachexia remains controversial but is currently an active area of research. Several new targeted drugs are under investigation, and we hope to open a new prospect in the management of cancer cachexia in the future.

  • Backgrounds/Aims: The hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) is classified as the advanced stage (BCLC stage C) with extremely poor prognosis, and in current guidelines is recommended for systemic therapy. This study aimed to evaluate the surgical outcomes and long-term prognosis after hepatic resection (HR) for patients who have HCC combined with PVTT. Methods: We retrospectively analyzed 332 patients who underwent HR for HCC with PVTT at ten tertiary referral hospitals in South Korea. Results: The median overall and recurrence-free survival after HR were 32.4 and 8.6 months, while the 1-, 3-, and 5-year overall survival rates were 75%, 48%, and 39%, respectively. In multivariate analysis, tumor number, tumor size, AFP, PIVKA-II, neutrophil-to-lymphocyte ratio, and albumin-bilirubin (ALBI) grade were significant prognostic factors. The risk scoring was developed using these seven factors-tumor, inflammation and hepatic function (TIF), to predict patient prognosis. The prognosis of the patients was well stratified according to the scores (log-rank test, p < 0.001). Conclusions: HR for patients who have HCC combined with PVTT provided favorable survival outcomes. The risk scoring was useful in predicting prognosis, and determining the appropriate treatment strategy for those patients who have HCC with PVTT.
