The purpose of this study is to report and demonstrate the effect of Korean medical treatment on a wedge resection of a lung patient with mucinous adenocarcinoma. The patient was an 84-year-old female who was diagnosed with mucinous adenocarcinoma and underwent wedge resection. The patient was treated with acupuncture and herbal medicine (Banhahubak-tang and Gamiondam-tang). The EORTC Quality of Life Questionnaire, Core 30 (EORTC QLQ-C30), EORTC Quality of Life Questionnaire, Lung Cancer 13 (EORTC QLQ-LC13), numeric rating scale (NRS), and the Global Assessment (G/A) were used to assess the changes in symptoms, including operation site pain and dyspnea. After treatment, the patient showed improvement in operation site pain and dyspnea, based on the NRS and G/A. However, dyspnea and pain were aggravated based on the EORTC QLQ-C30 and EORTC QLQ-LC13. Therefore, Korean medicine may have a substantial benefit for patients with mucinous adenocarcinoma after wedge resection of the lung.

Objective: Arrestins act as mediators of G protein-coupled receptor (GPCR) desensitization and trafficking, also actin as a scaffold for many intracellular signaling network. The role that ${\beta}$-arrestin 1 plays in gastric cardiac adenocarcinoma (GCA) and its clinicopathologic significance are untouched. Methods: Fifty patients with gastric cardiac adenocarcinoma were retrospectively enrolled and ${\beta}$-arrestin 1 was detected using immunohistochemistry in tissue samples. Results: Nuclear expression of ${\beta}$-arrestin 1 was observed in 78% of GCA samples (39/50) and cytoplasmic expression in 70% (35/50). ${\beta}$-arrestin 1 could be found in both nucleus and cytoplasm of 54% GCA (27/50) or in either of them in 94% (47/50). ${\beta}$-arrestin 1 protein positivity in well/moderately differentiated carcinomas was significantly higher than that in poorly differentiated carcinomas (P=0.005). We found increased expression of ${\beta}$-arrestin 1 in cytoplasm was correlated with lymph nodal metastasis (P=0.002) and pathological lymph nodal staging (P=0.030). We also found ${\beta}$-arrestin 1 to be over-expressed in glandular epithelia cells of mucinous adenocarcinoma, a tumour type associated with an adverse outcome of gastric cardiac adenocarcinoma (P=0.022). Conclusion: ${\beta}$-arrestin 1 is over-expressed in the nucleus and/or cytoplasm of gastric cardiac adenocarcinoma. However, ${\beta}$-arrestin 1 has no relationship with the prognosis of gastric cardiac adenocarcinoma (P>0.05). Our data imply that ${\beta}$-arrestin 1 in cytoplasm may be involved in differentiation and metastasis of gastric cardiac adenocarcinoma.

Objective: To investigate the association between CT imaging features and survival outcomes in patients with primary invasive mucinous adenocarcinoma (IMA). Materials and Methods: Preoperative CT image findings were consecutively evaluated in 317 patients with resected IMA from January 2011 to December 2015. The association between CT features and long-term survival were assessed by univariate analysis. The independent prognostic factors were identified by the multivariate Cox regression analyses. The survival comparison of IMA patients was investigated using the Kaplan-Meier method and propensity scores. Furthermore, the prognostic impact of CT features was assessed based on different imaging subtypes, and the results were adjusted using the Bonferroni method. Results: The median follow-up time was 52.8 months; the 5-year disease-free survival (DFS) and overall survival rates of resected IMAs were 68.5% and 77.6%, respectively. The univariate analyses of all IMA patients demonstrated that 15 CT imaging features, in addition to the clinicopathologic characteristics, significantly correlated with the recurrence or death of IMA patients. The multivariable analysis revealed that five of them, including imaging subtype (p = 0.002), spiculation (p < 0.001), tumor density (p = 0.008), air bronchogram (p < 0.001), emphysema (p < 0.001), and location (p = 0.029) were independent prognostic factors. The subgroup analysis demonstrated that pneumonic-type IMA had a significantly worse prognosis than solitary-type IMA. Moreover, for solitary-type IMAs, the most independent CT imaging biomarkers were air bronchogram and emphysema with an adjusted p value less than 0.05; for pneumonic-type IMA, the tumors with mixed consolidation and ground-glass opacity were associated with a longer DFS (adjusted p = 0.012). Conclusion: CT imaging features characteristic of IMA may provide prognostic information and individual risk assessment in addition to the recognized clinical predictors.

Objective: To compare pneumonic-type invasive mucinous adenocarcinoma (pIMA) confined to a single lobe with clinical T2, T3, and T4 stage lung cancer without pathological node metastasis regarding survival after curative surgery and to identify prognostic factors for pIMA. Materials and Methods: From January 2010 to December 2017, 41 patients (15 male; mean age ± standard deviation, 66.0 ± 9.9 years) who had pIMA confined to a single lobe on computed tomography (CT) and underwent curative surgery were identified in two tertiary hospitals. Three hundred and thirteen patients (222 male; 66.3 ± 9.4 years) who had non-small cell lung cancer (NSCLC) without pathological node metastasis and underwent curative surgery in one participating institution formed a reference group. Relapse-free survival (RFS) and overall survival (OS) were calculated using the Kaplan-Meier method. Cox proportional hazard regression analysis was performed to identify factors associated with the survival of patients with pIMA. Results: The 5-year RFS and OS rates in patients with pIMA were 33.1% and 56.0%, respectively, compared with 74.3% and 91%, 64.3% and 71.8%, and 46.9% and 49.5% for patients with clinical stage T2, T3, and T4 NSCLC in the reference group, respectively. The RFS of patients with pIMA was comparable to that of patients with clinical stage T4 NSCLC and significantly worse than that of patients with clinical stage T3 NSCLC (p = 0.012). The differences in OS between patients with pIMA and those with clinical stage T3 or T4 NSCLC were not significant (p = 0.11 and p = 0.37, respectively). In patients with pIMA, the presence of separate nodules was a significant factor associated with poor RFS and OS {unadjusted hazard ratio (HR), 4.66 (95% confidence interval [CI], 1.95-11.11), p < 0.001 for RFS; adjusted HR, 4.53 (95% CI, 1.59-12.89), p = 0.005 for OS}. Conclusion: The RFS of patients with pIMA was comparable to that of patients with clinical stage T4 lung cancer. Separate nodules on CT were associated with poor RFS and OS in patients with pIMA.

Adenocarcinomas (AC) are the most frequently encountered carcinomas. It may be quite challenging to detect the primary origin when those carcinomas metastasize and the first finding is a metastatic tumor. This study evaluated the role of sex hormone binding globulin (SHBG) positivity in tumor cells in the subclassification and detection of the original organ of adenocarcinomas. Between 1994 and 2008, 64 sections of normal tissue belonging to ten organs, and 116 cases diagnosed as adenoid cystic carcinoma and mucoepidermoid carcinoma of the salivary gland, lung adenocarcinoma, invasive ductal carcinoma of the breast, adenocarcinoma of stomach, colon, gallbladder, pancreas and prostate, endometrial adenocarcinoma and serous adenocarcinoma and mucinous adenocarcinoma of the ovary, were sent to the laboratory at the Department of Pathology at the Yuzuncu Yil University School of Medicine, where they were stained immunohistochemically, using antibodies against SHBG. The SHBG immunoreactivity in both the tumor cells and normal cells, together with the type, diffuseness and intensity of the staining were then evaluated. In the differential diagnosis of the adenocarcinomas of the organs, including the glandular structures, impressively valuable results are encountered in the tumor cells, whether the SHBG immunopositivity is evaluated alone or together with other IHC markers. Further extensive research with a larger number of cases, including instances of cholangiocarcinoma and cervix uteri AC [which we could not include in the study for technical reasons] should be performed, in order to appropriately evaluate the role of SHBG in the differential diagnosis of AC.

Application of magnetic resonance imaging (MRI) for assessment of pulmonary disease has been limited, due to susceptibility to cardiac pulsation, respiratory motion, and inhomogeneity of the magnetic field of the lung. With technical advances of MRI and unmet clinical needs for more accurate diagnosis and assessment of the disease, however, the use of MRI for evaluation of the lung has broadened. Herein, we present a case of pneumonic-type lung adenocarcinoma in a patient with history of anaphylactic shock to iodinated contrast medium, in which MRI played a critical role for targeted lung biopsy and cancer staging. Through this paper, we would like to report potential value of MRI in assessment of lung cancer.
