  • We report a case of long term survival on trastuzumab based treatment. A 51-year-old man with dyspepsia received esophagogastroduodenoscopy on another hospital and was transferred for further evaluation under the impression of advanced gastric cancer, Borrmann type III, antrum, lesser curvature. After further studies in our hospital, the patient was diagnosed with advanced gastric cancer, adenocarcinoma, moderately differentiated with pancreas invasion and lymph node metastasis. Though he was recommended with chemotherapy, he refused and left for oriental herbal medicine. After 4 months, the patient was admitted through emergency room for hematemesis. Diagnosed with gastric outlet obstruction due to gastric cancer in the antrum, he underwent the placement of pyloric metal stent insertion. Immunohistochemical staining showed HER2-positive finding, and he was treated with palliative chemotherapy of trastuzumab, capecitabine, and cisplatin, 16 times during 11 months. The patient showed neutropenia after the therapy, so cisplatin was left out, and he received combination chemotherapy of trastuzumab and capecitabine, 34 times during 25 months. Response evaluation showed no remarkable change in extent of primary stomach cancer, lymph node metastasis, and regression of metastasis site, and the patient is continuing chemotherapy.

  • Previous studies have highlighted the pivotal role of the β-adrenergic receptor (β-AR) signaling pathway in stimulating cancer metastasis induced by chronic stress. According to the theory of traditional Korean medicine, chronic stress can induce Qi stagnation. Based on the traditional role of premature citrus unshiu peel in moving Qi, we hypothesized that an ethanol extract of premature citrus unshiu peel (EPCU) can attenuate chronic stress-induced cancer progression. In this study, we investigated the potential role of EPCU on modulating the adrenergic agonists-induced metastatic properties of liver cancer cells. Our findings revealed that adrenergic agonists, including norepinephrine (NE), epinephrine (E), and isoproterenol (ISO), augmented the migratory capacity of Hep3B human hepatocellular carcinoma cells, which was completely abrogated by EPCU treatment in a concentration-dependent manner. Consistently, EPCU inhibited the E-induced invasive property of Hep3B cells in a dose-dependent manner. These results suggest that EPCU efficiently attenuates adrenergic agonists-induced metastatic abilities of liver cancer cells. As a molecular mechanism, EPF suppressed the phosphorylation of major components of β-AR signaling pathway, including Src, signal transducer and activator of transcription 3 (STAT3) and ERK, induced by E treatment. Taken together, our results demonstrate that EPCU impedes the adrenergic agonists-driven metastatic potential of cancer cells by inhibiting β-AR signaling pathway. This study provides basic evidence supporting the probable use of premature citrus unshiu peel to prevent metastasis in liver cancer patients under chronic stress.

  • This study aims to assess the quality and performance of predictive models for colorectal cancer liver metastasis (CRCLM). A systematic review was performed to identify relevant studies from various databases. Studies that described or validated predictive models for CRCLM were included. The methodological quality of the predictive models was assessed. Model performance was evaluated by the reported area under the receiver operating characteristic curve (AUC). Of the 117 articles screened, seven studies comprising 14 predictive models were included. The distribution of included predictive models was as follows: radiomics (n = 3), logistic regression (n = 3), Cox regression (n = 2), nomogram (n = 3), support vector machine (SVM, n = 2), random forest (n = 2), and convolutional neural network (CNN, n = 2). Age, sex, carcinoembryonic antigen, and tumor staging (T and N stage) were the most frequently used clinicopathological predictors for CRCLM. The mean AUCs ranged from 0.697 to 0.870, with 86% of the models demonstrating clear discriminative ability (AUC > 0.70). A hybrid approach combining clinical and radiomic features with SVM provided the best performance, achieving an AUC of 0.870. The overall risk of bias was identified as high in 71% of the included studies. This review highlights the potential of predictive modeling to accurately predict the occurrence of CRCLM. Integrating clinicopathological and radiomic features with machine learning algorithms demonstrates superior predictive capabilities.

  • Combinations of multiple biomarkers representing distinct aspects of metastasis may have better prognostic value for breast cancer patients, especially those in late stages. In this study, we evaluated the protein levels of N-${\alpha}$-acetyltransferase 10 protein (Naa10p), synuclein-${\gamma}$ (SNCG), and phosphatase of regenerating liver-3 (PRL-3) in 365 patients with breast cancer by immunohistochemistry. Distinct prognostic subgroups of breast cancer were identified by combination of the three biomarkers. The Naa10p+SNCG-PRL-3-subgroup showed best prognosis with a median distant metastasis-free survival (DMFS) of 140 months, while the Naa10p-SNCG+PRL-3+subgroup had the worst prognosis with a median DMFS of 60.5 months. Multivariate analysis indicated Naa10p, SNCG, PRL-3, and the TNM classification were all independent prognostic factors for both DMFS and overall survival (OS). The three biomarker combination of Naa10p, SNCG and PRL-3 performed better in patients with lymph node metastasis, especially those with more advanced tumors than other subgroups. In conclusion, the combined expression profile of Naa10p, SNCG and PRL-3, alone or in combination with the TNM classification system, may provide a precise estimate of prognosis of breast cancer patients.

  • Background: The aim of this study was to investigate the general characteristics of patients with deep vein thrombosis (DVT) and pancreatic cancer as well as evaluate the relationship between mean platelet volume (MPV), DVT and survival. Materials and Methods: Seventy-seven patients with pancreatic cancer, who were admitted to Cukurova University Medical Faculty, Department of Medical Oncology, were enrolled in the study Results: The mean age was $59{\pm}20$. Forty-nine (63.6%) were men and 28 women (36.4%). Sixty-eight (88.3%) patients had adenocarcinoma and 9 (11.7%) had a malignant epithelial tumor. Thirty-six (46.7%) had liver metastasis at diagnosis. Twenty-six (33.8%) patients were alive, 20 (26%) were dead and in 31 (40.2%) the status was unknown. Only 14 (18.1%) patients had DVT. In 42 (54.5%) patients MPV values were normal, in 28 (36.4%) patients they were above normal, and in 7 (9.1%) patients they were below normal. There was no statistically significant difference between gender, tumour localization, chemotherapy and survival rates (p:0.56, p:0.11, p:0.21). There was no significant difference between DVT, gender, localisation, histological subtype, the presence of metastasis, stage and if the patient had been treated with chemotherapy (p:0.5, p:0.6, p:0.2, p:0.32, p:0.1, p:0.84). There was also no significant difference between MPV and DVT (p:0.57) but there was a significant difference between liver metastasis and DVT (p:0.02). Age, stage, the presence of metastasis and DVT were prognostic in pancreatic cancer patients. Conclusions: Cases of pancreatic cancer with liver metastasis should be studied more carefully as thrombosis is more common in these patients.

  • Purpose: Treatment strategies for early gastric carcinoma (EGC) should be based on achieving a complete cure, but clear indications for limited surgery have not been established. We investigated surgical outcomes for early gastric cancer to determine the optimal? treatment strategy for EGC. Materials and Methods: Subjects included 881 patients who underwent curative surgery for EGC between 1986 and 2003. Retrospective uni & multi-variate analysis for prognostic factors, factors affecting lymph node metastasis, and risk factors for cancer recurrence were analyzed. Results: In multivariate survival analyses, age, operation method, macroscopic appearance and lymph node stage proved to be independent prognostic factors. Lymph node metastasis, depth of tumor invasion, tumor size, lymphatic and venous invasion were also significant risk factors in multivariate analyses. In multivariate analyses for cancer recurrence, depth of tumor invasion and lymph node metastasis proved to be significant risk factors. Conclusion: Appropriate surgical treatment with lymph node dissection is necessary for EGC patients with risk factors for lymph node metastasis.

  • Purpose: Despite numorous reports on the relationship between the level of carcinoembryonic antigen (CEA) in gall bladder bile and liver metastasis in colorectal cancer, no similar studies have been carried out for gastric carcinomas. We, therefore, undertook the present study to establish the relationship between the gall bladder bile CEA and liver metastasis as well as the post-operative survival rate in gastric carcinoma patients with curative resections. Materials and Methods: In 373 gastric cancer patients (252 males, 121 females, age $21\∼76$ years) operated on at Kosin University Hospital between 1989 1996, the CEA concentration in the gall bladder bile was determined during the operation and the value was related to the rates of post-operative survival and liver metastasis during follow-up period. Results: The overall rate of patient survival decreased gradually with increase in TNM stage. The 13-year postoperative survival rates for stages Ia, Ib, II, IIIa, and IIIb were $95.7\%,\;92.5\%,\;79.9\%,\;50.9\%,\;and\;43.3\$, respectively, and the 10-year survival rate for stage IV was $22.6\%$. The patients with a high ($\geq$10 ng/ml) biliary CEA showed a significantly lower rate of survival than those with a low (<10 ng/ml) biliary CEA. The 13-year cumulative survival rate was $55.4\%$ for the high CEA group and $76.5\%$ for the low CEA group (P<0.01). Also, the patients with a high biliary CEA showed a significantly higher rate ($11.5\%$) of liver metastasis than those with a low biliary CEA ($1.9\%$) (P<0.000). In patients with TNM stages (I and II), the CEA level did not affect the post-operative survival rates ($95.4\%\;and87.7\%$ in the high and low CEA groups, P>0.10), but in those with high TNM stages (III and IV), the survival rate was significantly lower in the high CEA group ($25.9\%$) than in the low CEA group ($57.8\%$) (P<0.05). Conclusion: These result suggest that the gall bladder bile CEA level obtained in an advanced-staged gastric cancer operation may be used in predicting the post-operational survival rate and in sorting out patients with a high risk for cancer recurrence, especially in the liver area.

  • Purpose: E-cadherin and CD44H have been shown to play a role in the progression and the metastasis of tumors. This study evaluated the clinical correlations between expression of E-cadherin and CD44H and various clinicopathologic factors and the value of expressions of E-cadherin and CD44H as prognostic factors in Borrmann type IV gastric cancer. Materials and Methods: In 122 patients with Borrmann type IV gastric cancer, we performed the immunohistochemical stainings for E-cadherin and CD44H. We analyzed the correlation between the expressions of E-cadherin and CD44H and lymphatic invasion, venous invasion, perineural invasion, histologic type, lymph node metastasis, depth of invasion, stage, and peritoneal dissemination, and survival. Results: There were no correlations between reduced expression of E-cadherin and CD44H and lymphatic invasion, venous invasion, perineural invasion, histologic type, lymph node metastasis, depth of invasion, and stage. However, there was a significant correlation between lymph node metastasis and the lymphatic invasion (P=0.022). There was also a significant correlation between the peritoneal dissemination and CD44H expression (P=0.005). The 5-year survival rate was correlated with CD44H expression expression (P=0.026), peritoneal dissemination (P<0.01), depth of invasion (P<0.01), lymph node metastasis (P<0.01), stage of tumor (P<0.01), and lymphatic invasion (P<0.01). There was no correlation between expression of E-cadherin and survival rate. Conclusion: The expression of CD44H and peritoneal dissemination was correlated. The expression of CD44H was an independent prognostic factor in Borrmann type IV gastric cancer. Further prospective studies with a large number of cases are required.

  • Purpose : The differential diagnosis for a pulmonary nodule is intriguing in cancer patients. Metastasis might be a preferential diagnosis, and yet possibilities of other medical conditions still exist. Pulmonary tuberculosis should be enlisted in the differential diagnosis for a pulmonary nodule in cancer patients in Korea. This study was aimed at analyzing the incidence and clinical features of pulmonary tuberculosis that were misdiagnosed as pulmonary metastasis during radiologic follow-up in pediatric cancer patients. Methods : We retrospectively studied 422 cancer patients less than 18 years old in the Korea Cancer Center Hospital from January 2001 to June 2007. We collected episodes of lung metastasis of primary tumor and tuberculosis during treatment or follow-up, and analyzed medical records. Results : There were 5 cases of tuberculosis confirmed after surgery which were initially regarded as cancer. Two patients had respiratory symptoms such as cough and sputum but the other 3 patients did not. One patient had a family history of tuberculosis. Acid-fast M. tuberculosis was found in one case upon tissue specimen analysis. Two cases were Mantoux positive and the sputum examination was negative in all cases. The polymerase chain reaction for tuberculosis on a pathologic specimen was used to differentiate M. tuberculosis from non-tuberculosis mycobacterium (NTM). It was positive in one case. Lung lesions in one case showed a concurrence of tuberculosis along with lung metastasis. One of these patients died after cancer recurrence. Conclusion : It is necessary to consider the possibility of tuberculosis when a lung mass is newly detected during treatment or follow-up in patients with childhood cancer.

  • Purpose: This study was done to analyze symptom distress and spiritual well-being in patients with cancer according cancer diagnosis, metastasis, treatment stage, number of hospitalizations and treatment modality. Method: The participants, 285 patients being treated in one of ten general hospitals either as in- or out-patients, completed the McCorkle and Young(1978) Symptom Distress Scale translated and adapted by Uhm(1986) and the Spiritual Well-Being Scale by Paloutzian and Ellison(1982) translated by Choi(1990). Data collection was done from June 19 to September 30, 2006. Results: For symptom distress, there were significant differences for cancer diagnosis(p=.018), metastasis(p=.000), treatment stage(p=.000), number of hospitalizations(p=.000), and treatment modality(p=.002). For spiritual well-being, the only significant difference was for cancer diagnosis(p=.002). Patients with ovarian/uterine cancer had the lowest spiritual well-being. Conclusion: For patients with cancer, symptom distress was significantly different for illness and treatment factors, in particular, stage of illness, while for spiritual well-being, patients with uterine ovarian cancer had the lowest spiritual level. These results indicate a need to develop nursing interventions to decrease symptom distress in patients according to treatment stage and to promote spiritual well-being, particularly in women with ovarian/uterine cancer.
