Abstract
Intensity-modulated radiation therapy (IMRT) has become a popular choice for breast cancer treatment. We aimed to evaluate and compare the robustness of each optimization method used for breast IMRT using TomoTherapy. A retrospective analysis was performed on 10 patients with left breast cancer. For each optimization method (clipping, virtual bolus, and skin flash), a corresponding 50 Gy/25 fr plan was created in the helical and direct TomoTherapy modes. The dose-volume histogram parameters were compared after shifting the patients anteriorly and posteriorly. In the helical mode, when the patient was not shifted, the median D1cc (minimum dose delivered to 1 cc of the organ volume) of the breast skin for the clipping and virtual bolus plans was 52.2 (interquartile range: 51.9-52.6) and 50.4 (50.1-50.8) Gy, respectively. After an anterior shift, D1cc of the breast skin for the clipping and virtual bolus plans was 56.0 (55.6-56.8) and 50.9 (50.5-51.3) Gy, respectively. When the direct mode was used without shifting the patient, D1cc of the breast skin for the clipping, virtual bolus, and skin flash plans was 52.6 (51.9-53.1), 53.4 (52.6-53.9), and 52.3 (51.7-53.0) Gy, respectively. After shifting anteriorly, D1cc of the breast skin for the clipping, virtual bolus, and skin flash plans was 55.6 (54.1-56.4), 52.4 (52.0-53.0), and 53.6 (52.6-54.6) Gy, respectively. The clipping method is not sufficient for breast IMRT. The virtual bolus and skin flash methods were more robust optimization methods according to our analyses.

Abstract
PURPOSE The CyberKnife system is a specialized device for non-coplanar irradiation; however, it possesses the geometric restriction that the beam cannot be irradiated from under the treatment couch. Prone positioning is expected to reduce the dose to normal lung tissue in spinal stereotactic body radiotherapy (SBRT) owing to the efficiency of beam arrangement; however, respiratory motion occurs. Therefore, the Xsight spine prone tracking (XSPT) system is used to reduce the effects of respiratory motion. The purpose of this study was to evaluate the motion-tracking error of the spine in the prone position. MATERIALS AND METHODS Data from all 25 patients who underwent spinal SBRT at our institution between April 2020 and February 2022 using CyberKnife (VSI, version 11.1.0) with the XSPT tracking system were retrospectively analyzed using log files. The tumor motion, correlation, and prediction errors for each patient were examined. Furthermore, to assess the potential relationships between the parameters, the relationships between the tumor-motion amplitudes and correlation or prediction errors were investigated using linear regression. RESULTS The tumor-motion amplitudes in each direction were as follows: superior-inferior (SI), 0.51 ± 0.39 mm; left-right (LR), 0.37 ± 0.29 mm; and anterior-posterior (AP), 3.43 ± 1.63 mm. The overall mean correlation and prediction errors were 0.66 ± 0.48 mm and 0.06 ± 0.07 mm, respectively. The prediction errors were strongly correlated with the tumor-motion amplitudes, whereas the correlation errors were not. CONCLUSIONS This study demonstrated that the correlation error of spinal SBRT in the prone position is sufficiently small to be independent of the tumor-motion amplitude. Furthermore, the prediction error is small, contributing only slightly to the tracking error. These findings will improve the understanding of how to compensate for respiratory-motion uncertainty in the prone position.

Abstract
Purpose Real‐time tracking systems of moving respiratory targets such as CyberKnife, Radixact, or Vero4DRT are an advanced robotic radiotherapy device used to deliver stereotactic body radiotherapy (SBRT). The internal target volume (ITV) of lung tumors is assessed through a fiducial marker fusion using four‐dimensional computed tomography (CT). It is important to minimize the ITV to protect normal lung tissue from exposure to radiation and the associated side effects post SBRT. However, the ITV may alter if there is a change in the position of the fiducial marker with respect to the tumor. This study investigated the relationship between fiducial marker position and the ITV in order to prevent radiation exposure of normal lung tissue, and correct target coverage. Materials and methods This study retrospectively reviewed 230 lung cancer patients who received a fiducial marker for SBRT between April 2015 and September 2021. The distance of the fiducial marker to the gross tumor volume (GTV) in the expiratory (dex) and inspiratory (din) CT, and the ratio of the ITV/V(GTVex), were investigated. Results Upon comparing each lobe, although there was no significant difference in the ddiff and the ITV/V(GTVex) between all lobes for dex < 10 mm, there was significant difference in the ddiff and the ITV/V(GTVex) between the lower and upper lobes for dex ≥ 10 mm (p < 0.05). Moreover, there was significant difference in the ddiff and the ITV/V(GTVex) between dex ≥10 mm and dex < 10 mm in all lung regions (p < 0.05). Conclusion The ITV that had no margin from GTVs increased when dex was ≥10 mm for all lung regions (p < 0.05). Furthermore, the increase in ITV tended to be greater in the lower lung lobe. These findings can help decrease the possibility of adverse events post SBRT, and correct target coverage.

Abstract
Background Concurrent chemoradiotherapy (CCRT) followed by durvalumab is the standard of care for unresectable locally-advanced non-small cell carcinoma (LA-NSCLC). However, a major concern about administration of durvalumab after CCRT is whether the incidence of symptomatic radiation pneumonitis (RP) may increase or not. In the present analysis, we report the initial results of CCRT followed by durvalumab in patients with LA-NSCLC in a real-world setting with focus on predicting factors for symptomatic RP. Methods Patients who were pathologically diagnosed as NSCLC and initiated treatment with CCRT followed by durvalumab between July 2018 to December 2019 were eligible for this study. Patients were included if they completed the planned CRT course and administered at least one course of durvalumab. We retrospectively investigated the preliminary survival outcome and incidence and predicting factors for symptomatic RP. Results Of the 67 patients who planned CCRT, 63 patients completed the entire CCRT course. Of these, 56 patients proceeded to consolidation with durvalumab. The median time to eternal discontinuation of durvalumab was 9.7 months. The cumulative proportion of the patients who exhibited symptomatic RP was 30, 40 and 44% at 3, 6 and 12 months, respectively. In multivariate analyses, pulmonary fibrosis score and lung V40 were significant predictive factors for symptomatic RP (p < 0.001, HR: 7.83, 95% CI: 3.38–18.13, and p = 0.034, HR: 3.17, 95% CI: 1.09–9.19, respectively). Conclusions Pulmonary fibrosis sore and lung V40 were significant predictive factors for symptomatic RP. We should be cautious about the administration of durvalumab for patients having subclinical pulmonary fibrosis. To our best knowledge, this is one of the first report showing the predictive value of high dose volumes to the lung in patients with LA-NSCLC who received CCRT followed by durvalumab.

Abstract
Collagen VI is distributed in the interstitium and is secreted mainly by mesenchymal stromal cells (MSCs) in skeletal muscle. Mutations in COL6A1-3 genes cause a spectrum of COL6-related myopathies. In this study, we performed a systemic transplantation study of human-induced pluripotent stem cell (iPSC)-derived MSCs (iMSCs) into neonatal immunodeficient COL6-related myopathy model (Col6a1KO/NSG) mice to validate the therapeutic potential. Engraftment of the donor cells and the resulting rescued collagen VI were observed at the quadriceps and diaphragm after intraperitoneal iMSC transplantation. Transplanted mice showed improvement in pathophysiological characteristics compared with untreated Col6a1KO/NSG mice. In detail, higher muscle regeneration in the transplanted mice resulted in increased muscle weight and enlarged myofibers. Eight-week-old mice showed increased muscle force and performed better in the grip and rotarod tests. Overall, these findings support the concept that systemic iMSC transplantation can be a therapeutic option for COL6-related myopathies.

Abstract
Background Mesenchymal stromal cells (MSCs) function as supportive cells on skeletal muscle homeostasis through several secretory factors including type 6 collagen (COL6). Several mutations of COL6A1, 2, and 3 genes cause Ullrich congenital muscular dystrophy (UCMD). Skeletal muscle regeneration deficiency has been reported as a characteristic phenotype in muscle biopsy samples of human UCMD patients and UCMD model mice. However, little is known about the COL6-dependent mechanism for the occurrence and progression of the deficiency. The purpose of this study was to clarify the pathological mechanism of UCMD by supplementing COL6 through cell transplantation. Methods To test whether COL6 supplementation has a therapeutic effect for UCMD, in vivo and in vitro experiments were conducted using four types of MSCs: (1) healthy donors derived-primary MSCs (pMSCs), (2) MSCs derived from healthy donor induced pluripotent stem cell (iMSCs), (3) COL6-knockout iMSCs (COL6KO-iMSCs), and (4) UCMD patient-derived iMSCs (UCMD-iMSCs). Results All four MSC types could engraft for at least 12 weeks when transplanted into the tibialis anterior muscles of immunodeficient UCMD model (Col6a1KO) mice. COL6 protein was restored by the MSC transplantation if the MSCs were not COL6-deficient (types 1 and 2). Moreover, muscle regeneration and maturation in Col6a1KO mice were promoted with the transplantation of the COL6-producing MSCs only in the region supplemented with COL6. Skeletal muscle satellite cells derived from UCMD model mice (Col6a1KO-MuSCs) co-cultured with type 1 or 2 MSCs showed improved proliferation, differentiation, and maturation, whereas those co-cultured with type 3 or 4 MSCs did not. Conclusions These findings indicate that COL6 supplementation improves muscle regeneration and maturation in UCMD model mice.

Abstract
In prostate stereotactic body radiation therapy (SBRT), hydrogel spacers are increasingly used. This study aimed to perform a dosimetry comparison of treatment plans using CyberKnife (CK), commonly used for prostate SBRT, Helical TomoTherapy (HT), and TrueBeam (TB) in patients with hydrogel spacer implantations. The data of 20 patients who received hydrogel spacer implantation for prostate SBRT were retrospectively analyzed. The prescription dose was 36.25 Gy in five fractions to 95% of the planning target volume (PTV; D95). The conformity index (CI), gradient index (GI), homogeneity index (HI), and dose‐volume histogram (DVH) were analyzed for the three modalities, using the same PTV margins. The monitor unit (MU) and the beam‐on‐time (BOT) values were subsequently compared. The CI of TB (0.93 ± 0.02) was significantly superior to those of CK (0.82 ± 0.03, p < 0.01) and HT (0.86 ± 0.03, p < 0.01). Similarly, the GI value of TB (3.59 ± 0.12) was significantly better than those of CK (4.31 ± 0.43, p < 0.01) and HT (4.52 ± 0.24, p < 0.01). The median doses to the bladder did not differ between the CK and TB (V18.1 Gy: 16.5% ± 4.5% vs. 15.8% ± 4.4%, p = 1.00), but were significantly higher for HT (V18.1 Gy: 33.2% ± 7.3%, p < 0.01 vs. CK, p < 0.01 vs. TB). The median rectal dose was significantly lower for TB (V18.1 Gy: 5.6% ± 4.5%) than for CK (V18.1 Gy: 11.2% ± 6.7%, p < 0.01) and HT (20.2% ± 8.3%, p < 0.01). TB had the shortest BOT (2.6 min; CK: 17.4 min, HT: 6.9 min). TB could create treatment plans dosimetrically comparable to those of CK when using the same margins, in patients with hydrogel spacers.

Abstract
Abstract
Introduction
Severe heart failure (HF) with congenital heart disease (CHD) have demonstrated life threatening disorder despite of remarkable progress in medical therapies. Autologous skeletal myoblast sheet transplantation therapy showed clinical efficacy for left ventricular dysfunction by cytokine paracrine effects, which are expected to be sufficiently effective against right ventricular (RV) dysfunction which is often seen in end-stage of CHD patients with severe HF.
Hypothesis
An autologous skeletal myoblast sheet transplantation alleviates RV dysfunction in a pressure-overloaded right heart in a porcine model.
Methods
Five-to-six-month-old Göttingen mini-pigs underwent pulmonary artery banding with vascular occluding system. To create the porcine model of chronic pressure-overloaded right heart, vascular occluding system was gradually inflated, over a month, to make pulmonary stenosis to banding velocity >3.0 m/s measured by echocardiography (UCG), and then fixed for another month. Two months after banding, autologous skeletal myoblast sheet was placed on the epicardium of the RV free wall and followed for 2 months. Groups were as follows: control (C, n=5), sheet implantation (S, n=5). Cardiac function was measured using UCG, cardiac computed tomography (CT), and cardiac catheterization (Cath). Two months after sheet implantation, hearts were dissected for histologic analysis.
Results
Before sheet implantation, RV dysfunction was equal in groups; however, 2 months after sheet implantation, RV dysfunction and myocardial ischemia was significantly ameliorated in group S than group C. On CT, RV ejection fraction exacerbation were well controlled in Group S compared to Group C (S 44.9±2.2 vs C 31.9±2.1% [p=0.0042]). UCG and Cath revealed well maintained systolic and diastolic function in Group S compared to Group C (Tei index: S 0.42±0.06 vs C 0.70±0.07 [p=0.0240], Fraction Area Change: S 45.8±7.8 vs C 19.5±1.3% [p=0.0240], Isovolumic Relaxation Time; S 44.3±9.2 vs C 97.3±9.5 ms [p=0.0304]). On C11-Acetate Positron Emission Tomography, myocardial ischemia was more prominent in Group C compared to Group S (K mono-Rest/Stress: S 3.17±0.69 vs C 2.03±0.65 min-1 [p=0.0421], Myocardial Blood Flow-Rest/Stress: S 3.22±0.39 vs C 2.13±0.92 min-1 [p=0.0421]). In histologic analysis, Group S presented less progressed hypertrophic change in periodic acid-Schiff stain (S 13.5±0.9 vs C 18.0±3.0 μg [p=0.0240]), anti-fibrotic changes in picrosirius red stain (S 3.0±0.3 vs C 4.2±0.2% [p=0.0421]), more angiogenesis in CD31 expression (S 18.3±1.5 vs C 10.7±2.8 / 104 μm2 [p=0.0240]), and less production of reactive oxygen species in fluorescent immunostaining (S 5.9±1.7 vs C 18.4±1.7% [p=0.0304]).
Conclusion
Autologous skeletal myoblast sheet transplantation alleviates cardiomyocyte Ischemia and RV dysfunction in a porcine model of pressure-overloaded right heart.

Abstract
Introduction
How to construct massive cardiac tissue and culture it with functional improvement may be crucial as cardiomyogenesis in failed heart. We previously presented that dynamic culture in a rotating wall vessel (RWV) bioreactor could provide a better culture environment for maintenance of the engineered 3D cardiac tissue. However, it is unknown about the effect of the tissue cultured in a RWV bioreactor on engraftment and improvement of function in the distressed rat heart.
Hypothesis
We hypothesized that the engineered 3D cardiac tissue cultured in a RWV bioreactor could improve its engraftment and lead recovery of cardiac function in rat infarction model.
Methods
We made engineered cardiac tissue by seeding 2.0 × 106 human induced pluripotent stem cell derived cardiomyocytes on the PLGA fiber sheet. It was cultured in the RWV bioreactor for seven days (RWV group). For the control, static culture has been done. After in vitro assessment, these tissues were transplanted to myocardial infarction model nude rats (sham, control, and RWV group, n=10, respectively) and cardiac performance was evaluated by ultrasonography. Four weeks after transplantation, we evaluated their hearts by histological analysis.
Results
The RWV group demonstrated maturation of cardiomyocytes evidenced by significantly higher expression of Troponin T (TnT), sarcomeric α actinin (SAA), connexin 43 (Cx43) and myosin heavy chain 7 (MYH7) than the control by Western blots (TnT; 2.7±1.0 vs. 1.0±0.4, p<0.01, SAA; 2.1±0.7 vs. 1.0±0.2, p<0.01, Cx 43; 2.0±0.6 vs. 1.0±0.1, p<0.05, MYH7; 10.9±2.7 vs. 1.0±0.1, p<0.01). In the culture supernatant, the concentration of cytokines related to angiogenesis was significantly higher in the RWV group than in the control (VEGF; 29.6±7.4 vs. 12.2±4.3pg/ml, p<0.01, HGF; 72.7±9.9 vs. 42.6±5.9pg/ml, p<0.01). Four weeks after transplantation, the left ventricular ejection fraction was significantly improved in the RWV group than in the control (RWV vs. control; 47±4.9 vs. 38±6.9%, p<0.01). On histological analysis, more engineered cardiac tissue survived in the RWV group than in the control (RWV vs. control; 7/10 vs. 3/10, p=0.18). A vascular-like structure double-stained with isolectin B4 and smooth muscle actin was partially observed in the transplanted tissue. LV remodeling exhibiting extracellular collagen deposition (fibrotic area, RWV vs. control; 17±4.3 vs. 24±5.2%, p<0.05) and cardiomyocyte hypertrophy (RWV vs. control; 16±1.7 vs. 18±2.1μm, p<0.05) was significantly attenuated in RWV group than in the control. Neovascularization was significantly noted in the RWV group compared with the control (capillary density, RWV vs. control; 545±113 vs. 356±92, p<0.01).
Conclusion
Functional engineered 3D cardiac tissue cultured in a RWV bioreactor could induce angiogenesis and improved its engraftment, leading significant improvement of cardiac function in rat infarction model.

Abstract
Abstract
Background
Recent studies have demonstrated the importance of high-density lipoprotein (HDL) functionality in the development of de novo coronary artery disease by using the cholesterol-efflux capacity, a measure of the ability of HDL to promote cholesterol removal from lipid-laden macrophages. Recently, we developed a rapid cell-free assay system to directly evaluate the capacity of HDL to accept additional cholesterol; the measurement of the cholesterol-uptake capacity (CUC) enables HDL functionality to be readily evaluated in our daily practice. However, prognostic implication of CUC measurement at the timing of percutaneous coronary intervention (PCI) remains unclear.
Purpose
We aimed to evaluate the association between baseline CUC and revascularization during follow-up in the patients who underwent PCI.
Methods
We retrospectively reviewed the patients who underwent PCI with follow-up coronary angiography (CAG) or ischemic-driven revascularization. The patients who had the frozen blood samples of which CUC were measurable at the index PCI and follow-up CAG or revascularization were enrolled. We excluded the patients under hemodialysis.
Results
Among a total of 703 consecutive patients who underwent PCI between Dec 2014 and Mar 2019, we finally enrolled 74 patients who underwent ischemic-driven revascularization (revascularization group) and 183 patients who underwent follow-up CAG without revascularization (non-revascularization group).There were no significant difference in baseline traditional cardiovascular risk factors between the groups. However, the presence of diabetes was significantly more frequent in the revascularization group (63.5% vs 41.0%; P=0.001) than in the non-revascularization group. CUC at the index PCI was significantly lower in the revascularization group than in the non-revascularization group (87.0±19.5 vs 93.9±19.2; P=0.004). Multivariate logistic regression analysis revealed that impaired HDL functionality assessed by decreased CUC level at the index PCI (odds ratio; 0.984, 95% confidence interval; 0.969–1.000) was independently associated with subsequent revascularization after PCI. Indeed, there was a graded inverse association between increasing tertiles of CUC levels and the incidence of revascularization during a median follow-up of 881 days (Figure). Especially in the subgroup analysis of non-diabetic patients, decreased CUC level at the index PCI was independently associated with subsequent revascularization (odds ratio; 0.947, 95% confidence interval; 0.915–0.981), while not in diabetic population.
Conclusion
Serum CUC level at the index procedure was associated with subsequent revascularization especially in non-diabetic patients who underwent PCI.

Abstract
BACKGROUND Muscle mass is often mentioned not to reflect muscle strength. For muscle mass assessment skeletal muscle index (SMI) is often used. We have reported that dual-energy X-ray absorptiometry (DXA)-derived SMI does not change with age in women, whereas the cross-sectional muscle area (CSMA) derived from computed tomography (CT) does. OBJECTIVES The present study aimed to compare CT and DXA for the assessment of muscle tissue. DESIGN AND SETTING Cross-sectional study in the local residents. PARTICIPANTS A total of 1818 subjects (age 40-89 years) randomly selected from community dwellers underwent CT examination of the right mid-thigh to measure the cross-sectional muscle area (CSMA). Skeletal muscle mass (SMM) was measured by DXA. The subjects performed physical function tests such as grip strength, knee extension strength, leg extension strength, and gait speed. The correlation between CT-derived CSMA and DXA-derived SMM along with their association with physical function was examined. RESULTS After controlling for related factors, the partial correlation coefficient of muscle cross-sectional area (CSA) with physical function was larger than that of DXA-derived SMM for gait speed in men (p=0.002) and knee extension strength in women (p=0.03). The partial correlation coefficient of quadriceps (Qc) CSA with physical function was larger than that of DXA-derived SMM for leg extension power in both sexes (p=0.01), gait speed in men (p<0.001), and knee extension strength in women (p<0.001). CONCLUSION Mid-thigh CT-derived CSMA, especially Qc CSA, showed significant associations with grip strength, knee extension strength, and leg extension power, which were equal to or stronger than those of DXA-derived SMM in community-dwelling middle-aged and older Japanese people. The mid-thigh CSMA may be a predictor of mobility disability, and is considered to be useful in the diagnosis of sarcopenia.

Abstract
Abstract
Background
High-mobility group box 1 protein (HMGB1) reportedly enhances CXCR4-positive bone marrow-derived mesenchymal stem cell (BM-MSC) recruitment to damaged tissue to promote tissue regeneration.
Purpose
Our aim of this study is to evaluate whether systemic administration of HMGB1 might promote tissue repair in a rat myocardial infarction (MI) model.
Methods
We prepared 26 MI model rats with high ligation of the left coronary artery. Two weeks later, HMGB1 (3 mg/kg/day) or phosphate-buffered saline (control: 3 mL/kg/day) was administered for 4 days via femoral vein. Cardiac performance was evaluated by ultrasonography, left ventricular (LV) remodeling via immunostaining. We then used immunostaining to examine MSC recruitment to damaged tissue in green fluorescent protein bone marrow transplantation (GFP-BMT) model rats, and also performed intravital imaging using two-photon microscopy to visualize BM-cells recruitment in real time.
Results
Compared with control rats, there was a significant improvement in the left ventricular ejection fraction of the HMGB1 group (HMGB1 vs. control: 48.6% ± 5.5% vs. 33.6% ± 5.4%; p<0.01) at 4 weeks after each administration. LV remodeling, characterized by interstitial fibrosis, cardiomyocyte hypertrophy, and a decrease of capillary density, was significantly attenuated in the HMGB1 group compared with control rats. On QT-PCR analysis, VEGF mRNA expression was significantly higher in the HMGB1 group than in the control (border zone; 1.6±0.6 vs. 1.1±0.2; p=0.02, septal zone; 1.1±0.1 vs. 0.9±0.1; p<0.01). In GFP-BMT rats, GFP+/PDGFR+ cells were significantly mobilized to the border zone in the HMGB1 group compared with the control (1331±197 vs. 615±45 /mm2; p<0.01), leading to formation of newly developed vasculature (Figure 1). In intravital imaging, more GFP+ cells were mobilized to the infarction area in the HMGB1 group than in the control, which was further enhanced at 12h later. Additionally, SDF-1 expression in the peri-infarction area increased significantly in MI rats compared with normal rats (MI vs. normal; 2.1±0.4 vs. 0.9±0.1; p<0.01), in where some cell-adhesions of vascular endothelial cells were destroyed.
Conclusions
Systemic administration of HMGB1 mobilized BM-MSCs to the damaged myocardium via the SDF-1/CXCR4 signaling complex. Those BM-MSCs might migrate to extracellular matrix in the border zone via the gap of each endothelial cell, leading to induction of angiogenesis and reduced fibrosis.

Abstract
The aim of the study was to explore the sonographic findings of fetuses with craniosynostosis and investigate their prognosis. We conducted a 5-year, multicenter retrospective study and collected data on patients with craniosynostosis diagnosed in the perinatal period. Of 41 cases, 30 cases (73%) were syndromic craniosynostosis, eight cases (20%) were non-syndromic craniosynostosis and the other three cases (7%) were secondary craniosynostosis of chromosomal deletion syndromes. The prenatal ultrasound detection rate was 61%. Half of the cases of syndromic craniosynostosis detected during the perinatal period were Pfeiffer syndrome; there were also six cases of Apert syndrome, three cases of Crouzon syndrome and other rare form of syndromic craniosynostosis (Beare-Stevenson syndrome, Saethre-Chotzen syndrome, cranioectodermal dysplasia, and thanatophoric dysplasia). Abnormal shape of the skull was the most common finding leading to prenatal diagnosis of craniosynostosis. Abnormal head biometry, which was the second most frequent finding, was closely correlated with deformation of the cranial shape. Three cases presented with ventriculomegaly and exophthalmos but normal cranial shape and size. The overall survival rate of infants with syndromic craniosynostosis was 79%, while all of the infants with non-syndromic craniosynostosis survived. In conclusion, prenatal diagnosis of craniosynostosis is difficult, especially when dysmorphic change of the fetal cranium is not evident. Abnormal head biometry and ventriculomegaly could potentially be additional markers of fetal craniosynostosis and consequently increase the prenatal detection rate.

Abstract
Background The treatment efficacy after CyberKnife stereotactic body radiotherapy (SBRT) have not been adequately addressed. The purpose of this study was to investigate pattern of recurrence according to irradiation field after CyberKnife SBRT for early-stage non-small cell lung cancer (NSCLC). Methods This retrospective study included patients with peripheral cT1/2N0M0 NSCLC that was treated with SBRT using a CyberKnife between May 2013 and March 2016 at single institute and followed up by more than two imaging examinations. Both operable and inoperable patients were included. Overall survival (OS) and progression-free survival (PFS) curves were estimated using the Kaplan-Meier method with 95% confidence intervals (CI). Cumulative incidence curves of recurrence were calculated and compared using the Gray's test. Results Total 71 patients were included and analyzed in this study. The median follow-up period for surviving patients was 34 months (range, 7-64 months). The 2-year OS and PFS rate were 93% (95% CI: 83-97%) and 77% (95% CI: 65-86%), respectively. The 2-year cumulative incidence rate of infield recurrence and out-of-field recurrence were 6% (95% CI: 2-14%) and 17% (95% CI: 9-27%), respectively. Gross tumor volume (GTV) ≥9 mL and diagnosis-to-treatment interval (DTI) ≥90 days were significantly associated with infield recurrence (P<0.001 and P=0.007), and epidermal growth factor receptor (EGFR) mutation was significantly associated with out-of-field recurrence (P=0.014). Conclusions Treatment efficacy after CyberKnife SBRT for peripheral early-stage NSCLC was identical to previous conventional linac-based SBRT reports. With short follow-up period, it was found that GTV and DTI were the significant predictive factor of infield recurrence, and EGFR mutation was the significant predictive factor of out-of-field recurrence.

Abstract
BACKGROUND The adaptation criteria for administration of stereotactic body radiotherapy (SBRT) to patients with lung cancer who previously underwent surgery and subsequently developed a second primary lung cancer (SPLC) or intra-parenchymal lung metastasis (IPLM) are controversial, unlike the criteria for repeat surgery. We aimed to evaluate the feasibility of SBRT for these patients. Factors associated with decreased respiratory function were also evaluated. MATERIAL AND METHODS Sixty-nine patients with 89 lesions who underwent SBRT between 2008 and 2017 were analyzed. Of these, 29 were diagnosed with SPLC while the remaining 40 had IPLM. The distribution of histological types was as follows: squamous cell carcinoma (n = 13 lesions); adenocarcinoma (n = 25); non-small cell carcinoma (n = 1); unknown histological type (n = 49). The prescribed doses to the planning target volume (PTV) were 50 Gy in five fractions for 85 lesions and 60 Gy in 10 fractions for four lesions at PTV mean. RESULTS Over a median follow-up period of 55 months, the 4-year overall survival and local control rates were 50.3% and 87.6%, respectively. Six patients experienced grade 2 radiation pneumonitis and one experienced grade 3. Two patients experienced grade 5 pulmonary fibrosis. Decreased respiratory function was observed in 10 patients (15.1%). On multivariate analysis, the presence of pulmonary disease before SBRT was the only statistically significant factor associated with decreased respiratory function. CONCLUSIONS SBRT is safe and feasible in patients with SPLC or IPLM previously treated surgically. Pre-existing pulmonary disease was a predictive factor for decreased respiratory function.

Abstract
RHOA missense mutations exist specifically in diffuse type gastric cancers (DGC) and are considered one of the DGC driver genes, but it is not fully understood how RHOA mutations contribute to DGC development. Here we examined how RHOA mutations affect cancer cell survival and cell motility. We revealed that cell survival was maintained by specific mutation sites, namely G17, Y42, and L57. Because these functional mutations suppressed MLC2 phosphorylation and actin stress fiber formation, we realized they act in a dominant-negative fashion against the ROCK pathway. Through the same inactivating mechanism that maintained cell survival, RHOA mutations also increased cell migration activity. Cell survival and migration studies on CLDN18-ARHGAP (CLG) fusions, which are known to be mutually exclusive to RHOA mutations, showed that CLG fusions complemented cell survival under RHOA knockdown condition and also induced cell migration. Site-directed mutagenesis analysis revealed the importance of the GAP domain and indicated that CLG fusions maintained RHOA in the inactive form. Taken together, these findings show that the inactivation of ROCK would be a key step in DGC development, so ROCK activation might provide novel therapeutic opportunities.

Abstract
Background Oligo-recurrence has been considered to confer improved prognosis than other oligometastatic conditions, and stereotactic body radiation therapy (SBRT) is considered as an option of local therapy for lung or liver metastases. The purpose of this study was to investigate the efficacy and safety of SBRT for lung and liver oligo-recurrent lesions and evaluate predictive factors for local control and prognosis. Methods This retrospective study included patients who presented with 1–3 matachronous lung or liver metastases, and treated with SBRT between May 2013 and March 2016 at a single institution. All patients harbored a controlled primary lesion. Patients with < 6 months of follow-up were excluded. Local control, progression free survival, and overall survival rates were analyzed according to the Kaplan–Meier product limit method. Univariable log-rank and multivariable Cox regression analyses were performed to clarify predictive factors for local control and prognosis. Toxicity was graded according to the Common Terminology Criteria for Adverse Events, version 4.0. Results Seventy-six patients with a total of 70 and 44 lung and liver lesions were included. The median follow-up period was 21 (range, 7–43) months. The 1-year local control, progression-free survival and overall survival rates were 89, 38 and 96%, respectively. Smaller gross tumor volume and additional chemotherapy after SBRT were significant predictive factors for better local control (p = 0.005 and p = 0.047), and the presence of a single metastatic lesion was a significant factor of good progression free survival (p = 0.008). Additional chemotherapy after SBRT was not a significant predictive factor but conferred to better overall survival (p = 0.078). Among colorectal cancer patients, post SBRT chemotherapy was significantly associated with better OS (p = 0.025). Over grade 3 adverse event was seen in only one patient. Conclusion SBRT is a safe and effective treatment for patients with lung and liver oligo-recurrence. Additional chemotherapy after SBRT improved local control, and single metastatic lesion was a significant predictive factor of better PFS in this study. Among colorectal cancer patients, additional chemotherapy after SBRT significantly associated better OS.

Abstract
The treatment of brainstem metastases remains a challenge as the brainstem itself is considered a neurological organ at risk. We aimed to investigate the efficacy and safety of CyberKnife hypofractionated stereotactic radiotherapy (HFSRT) for brainstem metastases, and to examine the balance between efficacy and safety for the management of neurological symptoms. A total of 26 lesions [pons (n = 18), medulla (n = 4) and midbrain (n = 4)] in 20 patients treated with CyberKnife hypofractionated stereotactic radiotherapy were retrospectively analyzed. The total radiation doses (18-30 Gy) were delivered in 3 or 5 equal fractions. The median follow-up was 6.5 (range, 0.5-38.0) months. The 6- and 12-month local control rates were 100% and 90%, respectively. Symptomatic failures, defined as the worsening and appearance of neurological symptoms due to the brainstem lesion after CyberKnife HFSRT, were observed in 6 patients [local failure (n = 1) and adverse events (n = 5). The symptomatic control and overall survival rates were 90% and 72% (after 6 months), respectively, and 76% and 53% (after 12 months), respectively. Longer symptomatic control was associated with site of lesion origin, and longer overall survival was associated with a graded prognostic assessment score of >2. To our knowledge, this is the second study to investigate the efficacy and safety of CyberKnife HFSRT for brainstem metastases. The local control rate was comparable with that of prior stereotactic radiosurgery studies. We propose a new evaluation criterion-'symptomatic control'-to evaluate the efficacy and safety of brainstem radiotherapy.

Abstract
Objective: The aims of this study were to investigate the frequency of symptomatic radiation pneumonitis (RP) after CyberKnife lung stereotactic body radiotherapy (SBRT) and to evaluate predictive factors of symptomatic RP. Methods: 56 patients with peripheral non-small-cell lung cancer were treated using the CyberKnife® VSI™ System (Accuracy Inc., Sunnyvale, CA) between May 2013 and September 2015. Total radiation doses ranged from 48 to 56 Gy, as delivered in four equal fractions. Symptomatic RP was defined as a grade of ≥2. Predictive factors for symptomatic RP were evaluated using univariate and multivariate analyses. Results: With a median follow-up duration of 12.5 months (range, 3–27 months), symptomatic RP was observed in 6 (10.7%) of the 56 patients. In the univariate analysis, percent vital capacity (p < 0.05), maximum tumour diameter (p < 0.05), gross tumour volume (p < 0.05), planning target volume (p < 0.01), mean lung dose (p < 0.01) and a normal lung volume receiving 5–50 Gy of radiation (V5–50) (p < 0.01) were identified as significant predictive factors for symptomatic RP. In the multivariate analysis, only a V25 >3.4% (p = 0.011) was identified as a significant predictive factor of symptomatic RP. Conclusion: The incidence of symptomatic RP after CyberKnife SBRT was almost identical to the incidences reported in the linear accelerator-based SBRT. A significant association was observed between a V25 >3.4% and the risk of developing symptomatic RP. Advances in knowledge: This is the first report that has investigated prognostic factors for symptomatic RP after CyberKnife SBRT for lung cancer. The newly developed scoring system may help to predict symptomatic RP.

Abstract
We reported a case of metastatic lung tumor, which was suspected as being a primary lung cancer because of its accompanying lesion mimicking atypical adenomatous hyperplasia(AAH) based on intraoperative needle biopsy findings. AAH is a preinvasive lesion or marginal lesion of primary lung cancer that is not accompanied by metastatic tumor. However, it needs to be distinguished pathologically from secondary changes of inflammation or fibrosis. In our case, the needle biopsy revealed AAH-like pathological findings, which indicates a primary lung cancer, and the standard lobectomy with lymph node dissection was performed, however, the final diagnosis turned out to be metastatic tumor. The rapidly enlarging tumor led to surrounding obstructive pneumonitis, which may have caused pathological changes mimicking AAH findings. In the case of obstructive pneumonitis, we must be careful to diagnose AAH, in addition to decisions about the surgical procedure especially when based on frozen section diagnosis.

Abstract
Extracellular signal-regulated kinase (ERK) has been implicated in the development of insulin resistance associated with obesity and type 2 diabetes mellitus. We have now examined the potential of pharmacological targeting of the ERK pathway with MEK (ERK kinase) inhibitors (PD184352 and PD0325901) for the treatment of obesity-associated insulin resistance. The effects of PD184352 and PD0325901 on the expression of adipocytokines and lipolysis activity were thus examined in 3T3-L1 adipocytes maintained in long-term culture as a model of adipocyte hypertrophy. Leptin receptor-deficient (db/db) mice and high-fat diet-fed KKAy mice, both of which are models of type 2 diabetes, were also treated orally with PD184352 to examine its effects on the diabetic condition. ERK activity was increased in hypertrophic 3T3-L1 adipocytes as well as in adipose tissue of db/db mice and high-fat diet-fed KKAy mice, and this enhanced ERK signaling was associated with dysregulation of adipocytokine expression and increased lipolysis activity. Specific blockade of the ERK pathway in hypertrophic 3T3-L1 adipocytes by MEK inhibitors ameliorated the dysregulation of adipocytokine expression and suppressed the enhanced lipolysis activity. Furthermore, repeated oral administration of PD184352 normalized hyperglycemia and hyperlipidemia and improved insulin sensitivity and glucose tolerance in the diabetic mice. These results suggest that sustained activation of the ERK pathway in adipocytes is associated with the pathogenesis of type 2 diabetes and that selective blockade of this pathway with MEK inhibitors warrants further study as a promising approach to the treatment of insulin resistance and type 2 diabetes.

Abstract
A tracheocutaneous fistula may develop when a tracheostomy orifice epithelializes during a prolonged course of healing or undernutrition. Various techniques for closing such fistulae have been reported. However, a standard procedure has not yet been established. We, herein, present a case involving a 35-year-old woman who developed a tracheocutaneous fistula after tracheostomy. We closed the fistula using two skin flaps to cover the tracheal lumen and skin defect, respectively. The advantage of this technique is that it allows the tracheal lumen to be covered by inversed skin epithelium and ensures that the suture line of the skin does not match up with that of the subcutaneous tissue.

Abstract
A 44-year-old man with locally advanced central lung cancer was treated by right lower lobe lung autotransplantation after pneumonectomy using an extracellular phosphate-buffered solution for cold lung preservation. The advantage of the ex vivo operation made it possible to perform safe and definitive cancer resection without massive bleeding. Cold lung preservation brought some advantages, such as reducing the risk of ischemia-reperfusion injury compared with warm ischemia and allowing enough time to achieve microscopically negative margins. The patient returned to normal life with minimum loss of pulmonary reserve and no recurrence of lung cancer for 6 months.
