Abstract
BACKGROUND/AIM The median age of subjects in many clinical trials of epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor conducted to date has been approximately 60 years. However, it is not uncommon to encounter EGFR gene-positive patients in their 70s or 80s. Based on information obtained from these clinical trials, EGFR gene-positive non-small cell lung cancer (NSCLC) patients are considered to be younger than EGFR-negative patients. In this study, we analyzed clinical data to identify whether this assumption is true. PATIENTS AND METHODS We retrospectively reviewed the medical records of NSCLC patients diagnosed in a multicenter clinical practice from 2009 to 2023. Patients included all cases of non-advanced and advanced NSCLC. RESULTS Information on 2,540 patients, including 605 EGFR gene-positive patients, was collected. The median age of EGFR-positive and EGFR-negative patients was 72 years and 71 years, respectively, and there was no significant difference in the age of patients between these two groups (p=0.7887). The most common age in these two groups was 70 years. Among the EGFR gene subtypes, the frequency of exon 19 deletion decreased with age, whereas that of EGFR L858R increased. CONCLUSION Patients in their 70s and 80s with non-small cell lung cancer were relatively frequently EGFR gene-positive. To avoid missing out on treatment opportunities, EGFR gene testing should also be performed on patients in this age group.

Abstract
Objective: Magnesium oxide is widely used for treating opioid-induced constipation, a serious analgesic-associated problem. Opioid analgesic users are often prescribed non-steroidal anti-inflammatory drugs, which are sometimes combined with acid suppressants to prevent gastrointestinal adverse events. Magnesium preparations combined with acid suppressants may diminish magnesium preparations' laxative effect. This study was aimed at evaluating the effect of magnesium preparations combined with acid suppressants on the incidence of opioid-induced constipation by using the Food and Drug Administration Adverse Event Reporting System. Methods: Adverse events were defined per the Medical Dictionary for Regulatory Activities; the term 'constipation (preferred term code: 10010774)' was used for analysis. After adjusting for patient background factors using propensity score matching, acid suppressants' effect on constipation incidence was evaluated in opioid users prescribed magnesium preparations alone as laxatives by using a test for independence. Key Findings: The Food and Drug Administration Adverse Event Reporting System contains 14,475,614 reports for January 2004 to December 2021. Significantly increased constipation incidence was related to magnesium preparations combined with acid suppressants, especially proton pump inhibitors (P < 0.0001, McNemar's test). Conclusion: Magnesium preparations combined with acid suppressants may diminish magnesium preparations' laxative effect; healthcare professionals should pay attention to this issue.

Abstract
Chest wall lipoma is a rare disease that might be asymptomatic and discovered incidentally. Chest wall lipomas are presumed to grow slowly, but no reports have evaluated the tumor volume doubling time (TVDT). The present study herein reports the case of a 35-year-old female patient with a relatively fast-growing chest wall lipoma. Lipomas have their characteristic shape and grow very slowly, so they are rarely completely resected, even though they are monitored and repeated imaging studies are performed. Homogeneous very low density, clear margins, and no invasion to the surrounding structure are characteristic finding on imaging, but some patients without these characteristics here have been reported here. As there has been no report of TVDT for chest wall lipoma, comparison was not possible, but TDVT for lipoma in this patient ranged from 235-412 days. Compared with reports that patients with non-small cell lung cancer showed TVDT of less than 450 days, TVDT in the patient described here did not appear to be slow. Accumulation of knowledge about this rare disease will help to elucidate it further.

Background
The hemodynamics in the left ventricle (LV) and the ascending aorta (AAO) before and after alcohol septal ablation (ASA) in patients with hypertrophic obstructive cardiomyopathy (HOCM) is elucidated.
Purpose
Our objective was to evaluate the pattern changes in AAO and intra-LV flow assessed by four-dimensional (4D) flow magnetic resonance imaging (MRI) before and after ASA and to clarify the association between 4D flow MRI-derived hemodynamic characteristics and the peak pressure gradient (PPG) in patients with drug-refractory HOCM.
Methods
In this retrospective observational study, 11 patients with HOCM underwent 4D flow MRI before and a week after ASA. The 4D flow MRI included blood flow visualization and quantification using streamline images. The combined score of vortex and helix in AAO was analyzed. The duration and phase count of the AAO vortex or helix flow [Figure 1a with vortex (yellow allow) before ASA and 1b without vortex after ASA] and the size of the intra-LV anterior vortex (Figure 1c with smaller vortex before ASA and 1d with larger vortex after ASA, both in white circle) were quantified. The correlation between the changes in hemodynamics and the resting PPG at LV outflow tract was also analyzed. We used the paired t-test for the comparison between before and after ASA and the Pearson"s correlation coefficient for the analysis.
Results
The combined score for the incidence of vortex and/or helix flow in AAO after ASA was significantly lower than that before ASA (1.45 ± 0.52 vs. 1.09 ± 0.30, p = 0.046). The duration (744 ± 291 ms vs. 467 ± 258 ms, p < 0.001) and phase count (14.8 ± 4.4 phases vs. 10.5 ± 5.8 phases, p < 0.001) of the vortex or helix flow in AAO were significantly decreased after ASA. The LV anterior vortex area after ASA was significantly larger than that before ASA (1628 ± 420 mm2 vs. 2974 ± 539 mm2, p = 0.009). The delta phase count of the AAO vortex or helix before and a week after ASA was significantly correlated with delta PPG before and a week after ASA (Figure 2a; R = 0.79, p = 0.004) and with delta PPG before and 6 months after ASA (Figure 2b; R = 0.83, p = 0.002).
Conclusions
Lower vortex or helix flow in AAO and larger diastolic vortex flow in LV were observed after ASA, which suggests the possibility to detect the changes of aberrant hemodynamics in HOCM. Abstract Figure. Streamline images before and after ASA

Abstract
The aim of this study was to investigate the association between the incidence of Guillain-Barré syndrome (GBS) and seasonal influenza vaccines using the United States Vaccine Adverse Event Reporting System. Using multiple logistic regression analysis, we calculated the adjusted reporting odds ratio (ROR) of GBS cases associated with seasonal influenza vaccines administered from August 2018 to July 2019. Additionally, we analyzed the time-to-onset profile. The total number of adverse events reported following vaccination during this period was 43,235. Most of the GBS patients received a cell culture-based quadrivalent inactivated influenza vaccine (42.2%), quadrivalent inactivated influenza vaccine (26.6%), or high-dose trivalent inactivated influenza vaccine (15.6%). The adjusted ROR of seasonal influenza vaccines for GBS was 3.44 (2.40-4.95). The adjusted ROR of sex (male) (as reference female) and 0.5-59 years (as reference ≥ 60 years) were 1.90 (0.73-4.95) and 1.57 (0.88-2.78). Male sex and advanced age were not risk factors for GBS. The median duration of GBS was 9.5 (4.0-21.5) days. GBS following seasonal influenza vaccination developed mainly within 14 days and 42 days at most. In sex-stratified analyses, the median durations of GBS in females and males were 12.0 (8.3-28.5) and 5.0 (3.0-15.5) days (P = 0.050). Therefore, our findings indicate that the incidence of GBS is associated with seasonal influenza vaccines, and careful monitoring of GBS is required for up to 42 days, especially in the first 14 days. Moreover, GBS may occur slightly earlier in males than in females.

Abstract
Lung metastasis and metachronous double primary lung cancer are both common and often present diagnostic challenges. We present a case of metachronous isolated contralateral lung metastasis from pulmonary adenosquamous carcinoma with EGFR mutation. A 75-yearold woman presented with left lung nodule on a routine follow-up chest radiograph. She had had surgery for pulmonary adenocarcinoma with EGFR Ex21 L858R mutation 6 years ago. She underwent surgical resection, and histologic findings revealed adenosquamous carcinoma with the same EGFR mutation. Re-assessment of the resected specimen of the primary tumor resected 6 years ago revealed the morphologically similarity to the left lung tumor. Based on morphological and genetic identity, final diagnosis was adenosquamous cell carcinoma and metachronous isolated contralateral lung metastasis. The diagnosis of metachronous isolated metastasis is difficult but important for appropriate management and prediction of prognosis. A careful pathological examination and evaluation of genetic abnormality are needed to make the correct diagnosis.

Abstract
PURPOSE The aim of this study is to reveal the vascular branching variation in SFC (splenic flexure cancer) patients using the preoperative three-dimensional computed tomography angiography with colonography (3D-CTAC). METHODS We retrospectively analyzed patients with SFC who underwent preoperative 3D-CTAC between January 2014 and December 2019. RESULTS Among 1256 colorectal cancer (CRC) patients, 96 (7.6%) manifested SFC. The arterial branching from the superior mesenteric artery (SMA) was classified into five patterns, as follows: (type 1A) the left branch of middle colic artery (LMCA) diverged from middle colic artery (MCA) (N = 47, 49.0%); (2A) the LMCA diverged from the MCA and the accessory middle colic artery (AMCA) (N = 26, 27.1%); (3A) the LMCA independently diverged from the SMA (N = 16, 16.7%); (4A) the LMCA independently diverged from the SMA and AMCA (N = 3, 3.1%); (5A) only the AMCA and the LMCA was absent (N = 4, 4.1%). Venous drainage was classified into four patterns, as follows: (type 1V) the SFV flows into the inferior mesenteric vein (IMV) then back to the splenic vein (N = 50, 52.1%); (2V) the SFV flows into the IMV then back to the superior mesenteric vein (SMV) (N = 19, 19.8%); (type 3V) the SFV independently flows into the splenic vein (N = 3, 3.1%); (type 4V) the SFV is absent (N = 24, 25.0%). CONCLUSION 3D-CTAC could reveal accurate preoperative tumor localization and vascular branching. These classifications should be helpful in performing accurate complete mesocolic excision and central vessel ligation for SFC.

Abstract
The present study aimed to evaluate clinical outcomes in patients with surgically resected non-small cell lung cancer (NSCLC) with anaplastic lymphoma kinase (ALK)-rearranged mutations. A matched-pair analysis in completely resected ALK-rearranged NSLC patients and those with neither ALK nor epidermal growth factor receptor (EGFR) mutations diagnosed at 11 institutes was performed between April 2008 and March 2019. A total of 51 patients with surgically resected ALK-rearranged NSCLC were included. Women constituted 68.6%, and smokers 29.4%. The median age was 65 years. In matched-pair analysis, disease-free survival and overall survival did not differ between patients with ALK-rearranged mutations and those without mutations. Post-recurrence survival in patients with ALK mutations was longer than that of patients with neither ALK nor epidermal growth factor receptor mutations. ALK genetic testing should be performed, even in elderly patients with NSCLC. Favorable prognosis might be expected after appropriate treatment for patients with recurrent ALK-mutated disease.

Abstract
Abstract
Background
The feature tracking (FT) technique has been proposed as a robust method to evaluate the myocardial strain using conventional cine magnetic resonance imaging (MRI) of the left ventricle. Data is limited regarding the relationship between FT-derived myocardial strain and diffuse myocardial fibrosis evaluated by T1 mapping in patients with non-ischemic dilated cardiomyopathy (NIDCM).
Purpose
The aim of this study was to evaluate the correlation between extracellular volume (ECV) by T1 mapping and myocardial strain by FT in patients with NIDCM.
Methods
A total of sixty-four patients with NIDCM (62±12 years) and 15 controls (62±11 years) were studied. Using a 1.5T MR scanner, pre- and post- T1 mapping images of LV wall at mid-ventricular level was acquired to calculate ECV by modified Look-Locker inversion recovery (MOLLI) sequence. Radial strain (RS), circumferential strain (CS) and longitudinal strain (LS) was assessed by FT technique. ECV and myocardial strain were compared using a 6-segment model at mid-ventricular level.
Results
Compared to the controls, the NIDCM patients had a significantly higher ECV (0.30±0.02 vs. 0.24±0.01, p<0.001) and impaired myocardial strain (RS, 24.2±3.0 vs. 52.2±6.2, p<0.001; CS, −7.5±2.1 vs. −15.3±2.2, p<0.001; LS −10.4±3.5 vs. −20.2±4.7, p<0.001, respectively). Similar results were obtained when comparing all 6 myocardial segments (segment 7–12) (all p values <0.001). In a segment-based analysis, a significant positive correlation was found between the ECV and CS (r=0.26 to 0.41; all p values <0.05), a negative correlation was found between the ECV and RS (r=−0.31 to −0.41; all p values <0.05). In a patient-based analysis, there were significant positive correlations between the ECV and CS (r=0.45, p<0.001), ECV and LS from 2-chamber view (r=0.30, p=0.006), ECV and LS from 4-chamber view (r=0.37, p<0.001). There was a significant negative correlation between the ECV and RS (r=−0.43, p<0.001) (FIGURE)
Conclusions
In NIDCM patients, severity of myocardial fibrosis evaluated by T1 mapping is associated with impaired myocardial strain by FT technique.

Abstract
Abstract
Background
The Catheter Ablation versus Standard Conventional Therapy in Patients with Left Ventricular Dysfunction and Atrial Fibrillation (CASTLE-AF) trial has shown that the catheter ablation (CA) for atrial fibrillation (AF) significantly reduced the risk of death and hospitalization for heart failure in patients with non-ischemic dilated cardiomyopathy (NIDCM) and AF (N Engl J Med 2018; 378:417–27). In addition, the Catheter Ablation Versus Medical Rate Control in Atrial Fibrillation and Systolic Dysfunction (CAMERA-MRI) study demonstrated that the absence of myocardial fibrosis on late gadolinium enhanced (LGE) magnetic resonance imaging (MRI) is associated with improvement of left ventricular systolic function after CA in NIDCM patients with AF (J Am Coll Cardiol 2017; 70:1949–61). Extracellular volume fraction (ECV) by T1 mapping has emerges as a non-invasive mean to quantify diffuse myocardial fibrosis.
Purpose
The aim of this study was to compare the predictive value of LGE-MRI and ECV by T1 mapping for the prediction of improvement of LVEF after CA in NIDCM patients.
Methods
A total of twenty-eight patients with NIDCM and AF (age: 67±10 years; 25 (89%) male; LVEF: 34.1±8.8%) were studied. Using a 1.5T MR scanner and 32 channel cardiac coils, cine MRI, LGE-MRI, pre- and post- T1 mapping images of LV wall at mid-ventricular level (modified Look-Locker inversion recovery sequence) were acquired. Myocardial fibrosis on LGE was defined as area with >5SD signal intensity of normal myocardium. ECV from six segments of mid ventricular level were averaged for each patient. All patients underwent CA for AF, and the improvement of LVEF before and after CA were evaluated by echocardiography.
Results
All patients restored sinus rhythm after CA at the time of echocardiography. The mean LVEF was 34.1±8.8% before CA and 49.1±12.0% after CA (p<0.001), resulting an improvement of 15.0±11.8%. Significant correlation was found between improvements in LVEF and amount of fibrosis on LGE-MRI (r=−0.40, p=0.034), improvement of LVEF and ECV (r=−0.55, p=0.008). In the ROC analysis, ECV had a higher discriminative ability for the improvement of LVEF after CA compared with amount of fibrosis on LGE-MRI (AUC 0.885 vs 0.650) (Figure).
Conclusions
In NIDCM patients with AF, ECV by T1 mapping had better predictive ability for improvement of LVEF after CA in comparison to LGE-MRI.

Abstract
BACKGROUND/AIM To describe real clinical outcomes in patients with non-small cell lung cancer who have uncommon epidermal growth factor receptor (EGFR) mutations. MATERIALS AND METHODS We performed a retrospective chart review from 15 medical institutes that cover a population of three million people from April 2008 to March 2019. RESULTS There were 102 patients with uncommon EGFR mutation. Progression-free survival (PFS) tended to be longer in patients receiving afatinib compared with first-generation EGFR tyrosine kinase inhibitors. PFS in patients treated with afatinib or osimertinib was significantly longer than in patients treated with gefitinib or erlotinib (p=0.030). Multivariate analysis also revealed the contribution of afatinib or osimertinib to increased survival. In patients with exon 20 insertions, chemotherapy was efficacious. CONCLUSION In treating patients with uncommon EGFR mutations, our results indicate longer-term survival might be achieved with second-generation or later TKIs and cytotoxic chemotherapeutic drugs.

Abstract
The aim of this study was to clarify the community pharmacy-level factors related to experiences of and attitudes toward collaboration with medical and nursing home care facilities. We conducted a postal questionnaire survey of all pharmacies in Gifu, Japan, assessing the experiences and attitudes of supervising pharmacists regarding the following activities related to collaboration between medical facilities and nursing home care facilities: regional care meetings/service adjustment meetings, case discussion conferences, joint workshops/continuing education conferences, community service, information sharing through medical cooperation networks, and pharmacists accompanying physicians on home care visits. The factors significantly related to inter-professional collaboration were the family pharmacist guidance fee and the number of patients offered pharmaceutical care through cooperation with other medical facilities. Items on attitudes toward collaborating with other medical facilities showed similar results. Overall, policies that support inter-professional collaboration to create a foundation, establish mechanisms to facilitate collaboration, and identify collaborative activities that can be carried out at each pharmacy should be developed.

Abstract
Anaplastic lymphoma kinase rearranged non-small-cell lung cancer is arare disease. Among them, asubset of patients exist who exhibit relatively slowly progressing symptoms and have oligo-metastases. In this article, we present two cases of ALK rearran-ged lung adenocarcinoma in patients who experienced postoperative oligo-recurrence. Both cases were treated with surgical resection and gamma knife irradiation for oligo-recurrence. After local therapy, the first patient remained disease free for over 23 months; the second for over 18 months. It appears that some patients with ALK rearranged NSCLC experience oligo-recurrence in their clinical course. For such patients, appropriate local therapy may be beneficial in improving both the quality of life and the prognosis.

Abstract
Various types of fluorescent lights are found in the dispensing rooms of medical facilities, such as hospitals and pharmacies, in Japan. However, to reduce electric power consumption, it was necessary to evaluate the substitution of fluorescent lighting with light emitting diode (LED) lighting, which has become widespread in recent years. We subjectively evaluated several types of medicines stored under various light sources and found that different color changes were induced in tablets. In this study, we focused on Perlodel ® tablets, containing 2.5 mg bromocriptine mesylate, as an example for the objective evaluation of the differences in the color change of tablets when stored under LED lighting and fluorescent lighting. High-performance liquid chromatography (HPLC) analysis of part of the tablet surface area revealed a change from white to light brown or dark brown after 28 days of irradiation, with a residual concentration of bromocriptine mesylate of 85.5 % under fluorescent lighting, 85.6 % under daylight-color LED lighting, 90.3 % under bulb-color LED lighting, and 99.2 % in the dark. In addition, the ultraviolet (UV)-visible spectral study of the absorbance of a photo-product at 400-550 nm indicated that the color change of the Perlodel® 2.5 mg tablet was caused by photochemical degradation of bromocriptine mesylate. Thus, this analysis of the photochemical changes in drugs stored under different light sources demonstrated the potency of LED lights. Through the objective evaluation of the color change, the cause of the color change was determined; this will allow us to develop a strategy that minimizes possible disadvantages to patients, such as a decrease in treatment efficacy owing to decomposition of the main component or adverse caused by decomposed matter.

Abstract
The aim of this study was to clarify the clinic-level factors related to experiences of and attitudes toward collaboration with community pharmacies. We conducted a postal questionnaire survey of all clinics in Gifu, Japan, assessing the experiences and attitudes of representative clinical staff regarding the following activities in collaboration with community pharmacists: regional care meetings/service adjustment meetings, case study conferences, joint workshops/continuing education conferences, community services, information sharing through medical cooperation networks, and accompanying community pharmacists during home care. The factors significantly related to experiences of joint workshops/continuing education conferences included home care visits (odds ratio [OR] 2.39) and a 100 % out-of-hospital prescription ratio (OR 4.80). In contrast, only home care visits were significantly associated with consideration of information sharing through medical cooperation networks and accompanying community pharmacists during home care (OR 2.06 and 11.91, respectively). Finally, the factors significantly associated with considering implementing case study conferences and joint workshops/continuing education conferences included home care visits (OR 4.64 and 2.98, respectively) and a 100% out-of-hospital prescription ratio (OR 4.64 and 6.38). Overall, having more opportunities to communicate with community pharmacists and other healthcare professionals appeared to facilitate clinics' consideration of collaboration with community pharmacies, along with actual experiences.

Chronic expanding hematoma (CEH) is a rare disease that is usually present as a large solitary pulmonary nodule. CEHs are slow growing, but processes underlying their development remain unknown. The present study herein reports the case of a 76-year-old male patient with CEH and discusses a number of CEH cases published in the literature. The majority of these previously described patients were Asians. The CEH in the present case was not a successfully resected one, but the patient's clinical course provided information concerning the natural history of the disease. During the clinical course, the patient underwent several chest computed tomography scans. For the present case report, the doubling time and volume change of the mass was calculated, which revealed that the lesion had an inconstant growth rate and that its onset was between 8.2-11.0 years before the patient succumbed to this disease. Accumulation of knowledge about this rare disease will help to elucidate it further.

Abstract
A 51-year-old woman, who was diagnosed as having limited cutaneous systemic scleroderma, presented with pulmonary nodules incidentally detected in a chest radiograph. The patient had surgical biopsy of the nodules. In microscopic examination of the specimens, proliferation, mitotic activity, and cellular anaplasia of spindle cells were present. Fluorodeoxyglucose-positron emission tomography showed tumors in lungs as well as uterus. The diagnosis of the tumor was pulmonary metastases from uterine leiomyosarcoma. We should be on alert the possibility of developing malignant disease in patient with this autoimmune disease. If it is certain that there is metastasis, we believe that therapy for the primary lesion will be preceded by biopsy and surgery for the metastatic lesions.

Abstract
Spleen metastasis is extremely rare in patients with lung cancer. However, recent improvements in imaging modalities may enable the antemortem diagnosis of spleen metastasis. The present study reports the case of a female patient with lung adenocarcinoma and spleen metastasis. The patient developed isolated spleen metastasis in the postoperative course. This rare metastasis was detected in a follow-up abdominal computed tomography (CT) scan without any symptoms, and was confirmed by fluorodeoxyglucose positron emission tomography (FDG-PET)/CT scan. Although very rare, chest physicians and thoracic surgeons should be alert to the possibility of spleen metastasis development when evaluating the follow-up abdominal CT scan. FDG-PET/CT scanning and an interventional approach should be considered to clarify the possibility of spleen metastasis.

Abstract
Postoperative lobar torsion is a rare and life-threatening complication. Several previous cases have been treated with completion lobectomy. We report successful surgical repair of middle lobar torsion after upper lobectomy. On postoperative day 4, the middle lobe was rotated approximately 150 degrees counterclockwise. The surface of the middle lobe appeared congestive, but its surface color, elasticity, and compliance improved 1 h after detorsion. We preserved the middle lobar function and prescribed warfarin for pulmonary vein thrombosis. When preserving a twisted lobe, it is important to consider the damage to the twisted lung, risk of thrombosis, and residual pulmonary function.

Abstract
In this study, we show that exposure of human lung cancer A549 cells to cisplatin (cis-diamminedichloroplatinum, CDDP) promotes production of nitric oxide (NO) through generation of reactive oxygen species (ROS) and resulting upregulation of inducible NO synthase (iNOS). The incubation of the cells with a NO donor, diethylenetriamine NONOate, not only reduced the CDDP-induced cell death and apoptotic alterations (induction of CCAAT-enhancer-binding protein homologous protein and caspase-3 activation), but also elevated proteolytic activity of 26S proteasome, suggesting that the activation of proteasome function contributes to the reduction of CDDP sensitivity by NO. Monitoring expression levels of six aldo-keto reductases (AKRs) (1A1, 1B1, 1B10, 1C1, 1C2, and 1C3) during the treatment with the NO donor and subsequent CDDP sensitivity test using the specific inhibitors also proposed that upregulation of AKR1B10 by NO is a key process for acquiring the CDDP resistance in A549 cells. Treatment with CDDP and NO increased amounts of nitrotyrosine protein adducts, indicative of peroxynitrite formation, and promoted the induction of AKR1B10, inferring a relationship between peroxynitrite formation and the enzyme upregulation in the cells. The treatment with CDDP or a ROS-related lipid aldehyde, 4-hydroxy-2-nonenal, facilitated the iNOS upregulation, which was restored by increasing the AKR1B10 expression. In contrast, the facilitation of NO production by CDDP treatment was hardly observed in AKR1B10-overexpressing A549 cells and established CDDP-resistant cancer cells (A549, LoVo, and PC3). Collectively, these results suggest the NO functions as a key regulator controlling AKR1B10 expression and 26S proteasome function leading to gain of the CDDP resistance.

Abstract
BACKGROUND Portal vein embolization (PVE) is considered to improve the safety of major hepatectomy. Various conditions might affect remnant liver hypertrophy after PVE. The aim of the present study was to clarify the factors that affect remnant liver hypertrophy and to establish a prediction formula for the hypertrophy ratio. METHODS Fifty-nine patients who underwent preoperative PVE for cholangiocarcinoma (39 patients), metastatic carcinoma (10 patients), hepatocellular carcinoma (8 patients), and other diseases (2 patients) were enrolled in this study. For the prediction of the hypertrophy ratio, a formula with stepwise multiple regression analysis was set up. The following parameters were used: age, gender, future liver remnant ratio to total liver (FLR%), plasma disappearance rate of indocyanine green (ICGK), platelet count, prothrombin activity, serum albumin, serum total bilirubin at the time of PVE and the maximum value before PVE (Max Bil), as well as a history of cholangitis, diabetes mellitus, and chemotherapy. RESULTS The mean hypertrophy ratio was 28.8%. The 5 parameters detected as predictive factors were age (p = 0.015), FLR% (p < 0.001), ICGK (p = 0.112), Max Bil (p < 0.001), and history of chemotherapy (p = 0.007). The following prediction formula was established: 101.6 - 0.78 × age - 0.88 × FLR% + 128 × ICGK - 1.48 × Max Bil (mg/dl) - 21.2 × chemotherapy. The value obtained using this formula significantly correlated with the actual value (r = 0.72, p < 0.001). A 10-fold cross validation also showed significant correlation (r = 0.62, p < 0.001), and a hypertrophy ratio <20% was predictable with a sensitivity of 100% and a specificity of 90.9%. Moreover, technetium-99m-diethylenetriaminepentaacetic acid-galactosyl human serum albumin scintigraphy showed a significantly smaller increase in the uptake ratio of the remnant liver in patients with prediction values <20% than in those with values ≥20% (6.8 vs. 20.8%, p = 0.030). CONCLUSIONS The prediction formula can prognosticate the hypertrophy ratio after PVE, which may provide a new therapeutic strategy for major hepatectomy.

Abstract
Although the prognosis of advanced thymic carconoma remains poor, previous reports have shown survival rates of 70% to 100% in patients with Masaoka stage I or stage II of the disease who were treated with surgery followed by adjuvant therapy. However, the role of adjuvant therapy in these stages is controversial. We retrospectively evaluated the outcome of 4 patients with Masaoka stage II thymic carcinoma who were treated with surgery alone between 1992 and 2008. No patient had stage I of the disease. Primary tumors were preoperatively evaluated by chest X-ray and computed tomography. Needle biopsy was not performed because the tumors were clinically diagnosed as noninvasive thymomas. The largest diameter of the primary tumor was 65 mm. Mediastinal lymphadenopathy was not detected by computed tomography. All patients underwent transsternal thymectomy. Mediastinal lymph node dissection was not performed. None of the patients received adjuvant chemotherapy and/or irradiation. Histopathologic examination revealed squamous cell carcinoma in 3 patients and undifferentiated carcinoma in one. Pathologic invasion to the adjacent organs or lymph node metastasis was not detected. All patients were alive and free from relapse at a follow-up of 72 months (range, 12-167 months). Radical resection without adjuvant therapy could be a treatment option for early Masaoka stage thymic carcinoma with low-grade histology.

Abstract
Carrier cells delivering a conditionally replicating adenovirus (CRAd), which selectively replicates in tumor cells and induces tumor cell lysis, have promising potential for treatment of cancer because CRAd-loaded carrier cells evade inhibition by neutralizing anti-adenovirus (Ad) antibodies and because the carrier cells are locally retained at the injection point after local injection. A previous study by Hamada et al. demonstrated that carrier cells (CRAd-containing cell fragments derived from the carrier cells) are engulfed into the target cells, probably through a pathway independent of the primary receptor for Ad, the coxsackievirus and Ad receptor (CAR) (Mol Ther, 15: 1121-1128; 2007); however, it remains to be elucidated whether carrier cells infected with a conventional CRAd, which is composed of subgroup-C Ad serotype-5 (Ad5), mediate antitumor effects on CAR-negative cells. In order to examine whether carrier cells delivering a conventional CRAd (Carrier-F5) induce lysis of CAR-negative tumor cells, CAR-positive and CAR-negative tumor cells were incubated with Carrier-F5. Carrier-F5 mediated efficient killing of CAR-positive tumor cells; however, CAR-negative tumor cells were almost refractory to Carrier-F5. On the other hand, carrier cells loaded with a fiber-substituted CRAd containing fiber proteins of Ad serotype-35 (Ad35) (CRAd-F35), which binds to human CD46 for infection, showed efficient killing of both CAR-positive and CAR-negative tumor cells. Intra-tumoral injection of carrier cells loaded with CRAd-F35 (Carrier-F35) also resulted in efficient regression of both CAR-positive and CAR-negative tumors. These results demonstrated that the expression levels of receptors for Ad are an important factor for CRAd-loaded carrier cell-mediated cancer therapy, and that Carrier-F35 would have potential as a cancer treatment for not only CAR-positive tumors but also CAR-negative tumors.

Abstract
A compact tomography camera system consisting of a photomultiplier tube, a multislit optical system, and a band-pass interference filter has been developed. The viewing area and spatial resolution can be configured by the arrangement of the slit system. The camera system has been specially designed for self-organized compact torus experiments having strong magnetohydrodynamics events with a submicrosecond time-scale. The developed system has been tested on a field-reversed configuration formed by the field-reversed theta-pinch. Performance evaluation of the system has been performed by comparison to the former optical system.

Abstract
BACKGROUND Once an anterior mediastinal tumor has been diagnosed as a thymoma, complete excision including the thymic gland and perithymic fat is currently the procedure of choice. However, little is known about the clinical outcome of grossly encapsulated thymomas excised only with the surrounding tissue while leaving a part of the thymic gland. METHODS A retrospective historical comparative study was conducted on 79 patients who had received surgery for stage I (n=25) or stage II (n=54) thymomas. Total thymectomy was performed in 61 patients (Total Thymectomy Group), whereas resection of tumors with only the surrounding tissue was carried out in 18 (Limited Thymectomy Group). The follow-up interval was longer in the Limited Thymectomy Group because these patients were treated longer ago (104.2+/-58.1 months vs 67.3+/-54.8 months, p<0.05). RESULTS One case in the Limited Thymectomy Group showed postoperative myasthenia gravis (5.6%). Two patients with multiple thymomas (2.5%) were treated with total thymectomy. One case in the Limited Thymectomy Group, which had been diagnosed as Masaoka stage II and WHO type B3 at initial surgery, recurred. None died of tumor progression in this study. Disease free survival rates at 10 years did not differ between the Limited Thymectomy and Total Thymectomy Groups (85.7% and 82.0%, respectively). There were no statistical differences in the incidence of postoperative myasthenia gravis and disease free survival between the two groups. CONCLUSION Resection of thymomas with surrounding tissue instead of total thymectomy can be indicated for stage I or II thymomas in light of disease free and overall survival, post-operative onset of MG, and the incidence of multiple lesions.

Abstract
Three morphologically and genetically distinct forms of the genus Carassius were collected from the Ob River system, Kazakhstan, Central Asia; Carassius carassius, Carassius gibelio gibelio and an unknown stock tentatively referred to as Carassius gibelio sub-species M. The last mentioned had 33-41 gill rakers, being intermediate between the other two forms (23-27 in C. carassius and 44-49 in C. g. gibelio), and five scales in the upper transverse series, less than in the others. It also had a relatively larger erythrocyte suggesting triploidy and an mtDNA haplotype distinct from all other known crucian carps. Comparative mtDNA phylogenetic analysis suggested that C. gibelio gibelio in the Ob River system was introduced from China and the Amur River, the same possibly being true for European C. gibelio gibelio based on published haplotypes. C. gibelio sub-species M is thought to be more widely distributed in central Asia, probably extending as far west as European Russia.

Abstract
Here we report a case of a rare thymic tumors histologically diagnosed as lipofibroadenoma. The patient was a 32-year-old male who displayed an anterior mediastinal tumor on a chest computed tomography (CT) scan while being treated for pneumonia. The tumor was localized within the thymus, and the diameter was 3 cm. No significant change was observed in the tumor on a CT scan taken 6 months after the 1st scan. Suspecting a thymoma from the CT and magnetic resonance imaging (MRI) findings, we performed a thymothymectomy via a median sternotomy. The histopathological diagnosis was a lipofibroadenoma of the thymus. The findings resembled fibroadenoma of the breast. Lymphocytes were scarce within the tumor with abundant interstitial stroma, and the tumor epithelial cells displayed restiform and dendritic structures. The epithelial cells were mostly negative for Ki-67 immunohistochemical staining. A very small amount of calcification was detected within the tumor using alizarin red staining. Based on the histopathological findings, it was considered to be a benign tumor with little growth potential, and which had been present for a long period of time.

Abstract
OBJECTIVE We evaluated retrospectively single-agent S-1 chemotherapy in non-small cell lung cancer patients in clinical practice. METHODS Sixteen consecutive patients treated with single-agent S-1 for NSCLC between July 2005 and June 2007 at the Department of Thoracic Surgery, Tsuchiura Kyodo General Hospital. The treatment schedule comprised oral administration of S-1 at 80-120 mg/day. One cycle of S-1 consisted of consecutive administration to 14 (10 cases)or 28(6 cases)days followed by a 14-day rest. RESULTS Patients profiles were: M/F: 11/5, median age 68 years old(range 51-83), PS 0/1/2/3: 2/6/5/3, adeno/squamous/large: 13/2/1, clinical stage 3A/3B/4: 3/4/9, prior chemotherapy regimens 0/1/2/3/4: 2/3/4/5/2, prior surgery/radiation: 12/5 were performed. Median number of delivered cycles was 5 cycles(range 1-13). Grade 3 hematological toxicities were anemia(6%)and thrombocytopenia(6%). Grade 3 non-hematological toxicities were nausea(6%)and vomiting(6%). Response of 13 patients could be evaluated after 2-4 cycles of S-1. Four partial responses were observed, for a response rate of 31%. The survival time was 67-852 days(average 14.0 months), 1-year survival rate was 74.0%, median time to progression was 4.6 m, and 1- year progression free survival was 25.0%. CONCLUSION Single-agent S-1 chemotherapy has modest activity and is the one of the important regimens and tolerable for elderly, poor-PS, recurrent patients with NSCLC in clinical practice.

Abstract
BACKGROUND Recently we developed a method to observe pulmonary micrometastasis by labeling cancer cells with green fluorescent protein (GFP). We applied the method for observation of micro-dissemination on the visceral pleura. MATERIALS AND METHODS RCN9 rat colon cancer cells labeled with GFP were injected into the pleural cavity of Fischer F344 rats. Six weeks after injection, the chest wall was resected under general anesthesia and the lung surface was observed by real-time confocal laser-scanning microscopy. Blood flow was visualized by intravenous injection of fluorescein isothiocyanate-labeled red blood cells, by which blood flow velocity was measured. RESULTS Dissemination was created in 4 out of 5 rats. Fifteen sites of micro-dissemination were observed (mean diameter, 35.8+/-13.3 microm). Blood flow velocity was 114.1+/-26.1 microm/s in the tumor tissue and 183.4+/-35.0 microm/s out of the tumor tissue. CONCLUSION We were able to observe pleural micro-dissemination. Blood flow velocity was significantly lower in the tumor tissue.

Abstract
23 year-old non-smoking male who had underwent bilateral video-assisted thoracoscopic surgery (VATS) bullectomy for spontaneous pneumothorax using surgical stapler (Endo GIA, Tyco Healthcare) 5 years before, referred to our hospital due to hemoptysis. Chest computed tomography (CT) revealed infiltrative shadow surrounding stapled-line at right pulmonary apex. Aspiration-shadows were scattered in right lung parenchyma. Bronchoscopy revealed bloody clot extended from right B1 to main bronchi. These findings suggested that the cause of bloody sputum was bleeding from the tissue around staples used in VATS bullectomy. On admission he treated with hemostatic agents, and bloody sputum and abnormal CT shadows disappeared. Metallic surgical staplers may cause airway bleeding after surgery in its chronic stage, although complications due to them are rare.

Abstract
The initial kinetics of cancer cell metastasis to organs requires investigation to establish an effective strategy against malignant disease. In vivo observation of pulmonary micrometastasis at an extremely early stage is of particular importance, and it is desirable from a clinical perspective to use an animal model with a normal immune system. RCN-9 cells labeled with green fluorescent protein were injected into the liver parenchyma of Fischer F344 male rats and the lungs were observed using real-time confocal laser scanning microscopy from 3 to 10 weeks after injection. Metastasis at the single cell level was observed throughout this period, but the number of pulmonary micrometastases did not increase significantly with time. The largest metastasis was 300 mum in diameter, and the mean size of the metastases did not increase with time. There were two types of micrometastases in terms of shape: round and linear metastases, with the latter resembling the pulmonary microvasculature. The precise location of each pulmonary micrometastasis was revealed by acridine orange infusion. We could observe a single cancer cell and a small cancer mass in endothelial and interstitial locations in vivo, and we found proliferating cancer cells both inside and outside of microvessels. Most of the pulmonary micrometastases stayed dormant as a single cell or a cancer mass of less than 100 microm in diameter until 10 weeks after cancer-cell injection into the liver.
