Abstract
OBJECTIVES To compare conventional procedures with the half-turned truncal switch operation (HTTSO) for the management of complete transposition of the great arteries with left ventricular outflow tract (LVOT) obstruction using time-resolved 3-dimensional magnetic resonance phase-contrast imaging. METHODS We identified 2 cases that underwent the Rastelli procedure and one case that underwent the Réparation a l'étage ventriculaire before 2002 [conventional procedures group (group C)], and 16 cases of HTTSO that were performed between 2002 and 2020 [HTTSO group (group H)]. Postoperative haemodynamics were assessed using time-resolved 3-dimensional magnetic resonance phase-contrast imaging in cases in both groups. RESULTS The median follow-up period was 20.4 years in group C, and 6.1 years in group H. In group C, all 3 patients underwent reoperation because of postoperative right ventricular outflow tract obstruction and/or insufficiency. In addition, permanent pacemaker implantation was needed in 1 patient because of complete atrioventricular block complicated by ventricular septal defect enlargement. In group H, reoperation for LVOT/right ventricular outflow tract obstruction was not needed. A time-resolved 3-dimensional magnetic resonance phase-contrast imaging examination revealed high energy loss and wall shear stress in the winding LVOT in the group C. In contrast, low energy loss and wall shear stress, with straight and smooth LVOT, were identified in group H. CONCLUSIONS HTTSO was shown to be superior to conventional procedures because a straight and wide LVOT could be obtained. Therefore, HTTSO should be the first choice for complete transposition of the great arteries with LVOT obstruction.

Abstract
BACKGROUND New therapeutic drugs have been developed for non-small cell lung cancer (NSCLC), and the prognosis of advanced NSCLC patients has improved. However, resistance to these drugs is a concern, and re-biopsy is necessary to determine the mechanism of drug resistance. There are many reports about the protocols for re-biopsy, including techniques such as bronchoscopy and computed tomography-guided needle biopsy (CTNB); however, there is no consensus on which method is optimal. Therefore, we retrospectively reviewed the bronchoscopy and CTNB re-biopsies conducted at our hospital. METHODS We retrospectively analyzed 79 cases of re-biopsies with bronchoscopy or CTNB in patients with NSCLC from January 2014 to December 2016 at our institute. RESULTS Forty-nine cases of bronchoscopy and 30 cases of CTNB were taken for re-biopsy. The diagnostic rates of bronchoscopy and CTNB were 83.7% and 100%, respectively (p = 0.023). The complication rates of bronchoscopy and CTNB were 18.4% and 36.7%, respectively (p = 0.11), with a statistically significant difference in the incidence of pneumothorax (0% vs. 23.3%, respectively; p < 0.01). Pneumothorax required drainage in 6.7% of all CTNB cases. There were no fatalities in either group. CONCLUSIONS CTNB showed a higher diagnostic rate; however, it was associated with a higher rate of complications such as pneumothorax. Hence, the optimal modality must be determined individually for each patient.

Abstract
Hermansky-Pudlak syndrome (HPS) is an autosomal recessive hereditary disease that may be complicated by progressive and potentially fatal interstitial pneumonia. We herein report a 64-year-old woman with interstitial pneumonia associated with HPS type 4 whom we treated with nintedanib after pirfenidone proved ineffective. To our knowledge, there have been no previous reports of nintedanib being used to treat a patient with HPS type 4. There is a need for clinical trials of antifibrotic agents, including nintedanib, pirfenidone, and new therapeutic agents with different mechanisms of action in these patients.

Abstract
AIM The aim of this study was to determine whether the paradigm of surgical intervention for faecal incontinence (FI) has changed between 2000 and 2013. METHOD This was a multi-centre retrospective study of patients who had undergone either sacral neuromodulation (SNM) or delayed sphincter repair or sphincteroplasty (SR) as a primary surgical intervention for FI in five centres in Europe and one in the United States. The flow of patients according to the intervention, sustainability of the treatment at a minimum follow-up of 5 years, complications and requirement for further interventions were recorded. RESULTS A total of 461 patients (median age 56 years, range 24-90 years, 41 men) had either SNM or SR as an index operation during the study period [SNM 284 (61.6%), SR 177 (38.4%)]. Among SNM patients, there were 169 revisional operations (change of battery and/or lead, re-siting or removal). At the time of last follow-up 203 patients (71.4%) continued to use SNM. Among SR patients, 30 (16.9%) had complications, most notably wound infection (22, 12.4%). During follow-up 32 patients (18.1%) crossed over to SNM. Comparing two 4-year periods (2000-2003 and 2007-2010), the proportion of patients operated on who had a circumferential sphincter defect of less than 90° was 48 (68%) and 45 (46%), respectively (P = 0.03), while those who had SNM as the primary intervention increased from 29% to 89% (P < 0.05). CONCLUSION The paradigm of surgical intervention for FI has changed with increasing use of SNM.

Abstract
A kinematically complete quasifree (p,pn) experiment in inverse kinematics was performed to study the structure of the Borromean nucleus ^{17}B, which had long been considered to have a neutron halo. By analyzing the momentum distributions and exclusive cross sections, we obtained the spectroscopic factors for 1s_{1/2} and 0d_{5/2} orbitals, and a surprisingly small percentage of 9(2)% was determined for 1s_{1/2}. Our finding of such a small 1s_{1/2} component and the halo features reported in prior experiments can be explained by the deformed relativistic Hartree-Bogoliubov theory in continuum, revealing a definite but not dominant neutron halo in ^{17}B. The present work gives the smallest s- or p-orbital component among known nuclei exhibiting halo features and implies that the dominant occupation of s or p orbitals is not a prerequisite for the occurrence of a neutron halo.

Abstract
To provide appropriate foods for elderly people with eating difficulties, it is necessary to take account of the ability of compensatory mastication such as tongue squeezing. However, the biomechanics of tongue squeezing is still unclear. The aim of present study is to investigate the effect of the initial mechanical properties of gels on the change in tongue pressure production during squeezing and swallowing. As test sample, nine kinds of gels with three fracture force and three fracture strain were prepared. Tongue pressure during squeezing and swallowing gels was measured by using an ultra-thin tongue pressure sensor with five measuring points attached on the hard palate in seven healthy participants, and analyzed at four phases; Initial squeeze, Middle squeeze, Last squeeze, and Swallowing. The maximal magnitude of tongue pressure was increased for gels with higher fracture force at most measuring points and was decreased for gels with higher fracture strain at some measuring points on the median line during Initial and Middle squeezing. However, no influence by fracture force and strain was found in magnitude during Last squeezing and Swallowing. The duration of tongue pressure increased for gels with higher force at most measuring points during Middle squeezing, although no influence by strain was found during each phase. The results clearly show how the initial fracture properties of gels influence on tongue pressure production during each phase of food oral processing, which clarified one aspect of squeezing with tongue, as the compensatory mastication.

Abstract
OBJECTIVES Studies investigating the association between radiation therapy and the efficacy of immune checkpoint inhibitors in advanced non-small-cell lung cancer have provided inconsistent results, likely due to relatively small cohort sizes. This study investigated the effect of previous thoracic radiation therapy on the efficacy of immune checkpoint inhibitor therapy in a large non-small-cell lung cancer cohort. PATIENTS AND METHODS We conducted a retrospective cohort study using data from 531 non-small-cell lung cancer patients who received monotherapy with programmed cell death protein 1/programmed death-ligand 1 inhibitors at nine institutions. The effects of thoracic radiation therapy on the efficacy of immune checkpoint inhibitors were investigated. RESULTS A total of 531 non-small-cell lung cancer patients treated with immune checkpoint inhibitors were included in this study. The progression-free survival period was significantly longer in patients that had received thoracic radiation therapy before immune checkpoint inhibitor therapy compared to those without previous thoracic radiation therapy (median progression-free survival 5.0 vs. 3.0 months, P = 0.0013). A multivariate analysis showed that thoracic radiation therapy was an independent predictive factor of improved progression-free survival (hazard ratio of progression-free survival: 0.79, P = 0.049). In contrast, extra-thoracic radiation therapy was associated with inferior outcomes (median progression-free survival 3.0 vs. 4.2 months, P = 0.0008). CONCLUSION Previous thoracic radiation therapy, but not prior extra-thoracic radiation therapy, enhanced the efficacy of anti-programmed cell death protein 1/programmed death-ligand 1 therapy in non-small-cell lung cancer patients.

Abstract
Background Stereotactic body radiation therapy (SBRT) is an established therapy for medically inoperable early-stage non-small cell lung cancer (NSCLC). Many elderly patients are medically inoperable owing to comorbidities. Therefore, SBRT may be a useful therapy for elderly patients. However, the application of SBRT for patients aged ≥ 80 years has not been completely elucidated. Therefore, this study aimed to assess the clinical utility of SBRT for elderly patients aged ≥ 80 years with pathologically proven early-stage NSCLC. Methods We retrospectively evaluated the data of patients aged ≥ 80 years with pathologically proven primary NSCLC who underwent SBRT at our institution between January 2009 and March 2020. Treatment outcomes and toxicities were analyzed. We used the Kaplan–Meier method to estimate survival curves and the log-rank test to compare the survival curves. We performed univariate and multivariate Cox regression analyses. p-values < 0.05 were regarded significant. Results Sixty-four patients (65 lesions) were included, and the median follow-up period was 38.7 (range 3.5–95.7) months. The median age was 82.9 (range 80.0–94.8) years. Sixteen patients were medically operable, and 48 patients were medically inoperable. The prescribed dose of SBRT was either 48 Gy in four fractions or 60 Gy in 10 fractions. The median survival time was 60.0 months (95% confidence interval, 43.5–71.1). The 1-, 3-, and 5-year local control, cancer-specific survival, progression-free survival, and overall survival rates were 98.4%, 98.4%, 81.0%, and 88.9%; 90.1%, 93.7%, 58.9%, and 68.3%; and 87.4%, 83.5%, 38.2%, and 47.5%, respectively. Multivariate analysis revealed that inoperability and solid nodules were the predictors of poor overall survival after SBRT in elderly patients. Two patients (3.1%) had grade 3 radiation pneumonitis, and one patient (1.6%) had grade 5 radiation pneumonitis. Conclusions SBRT was feasible in patients aged ≥ 80 years with NSCLC. It achieved good local control with minimal toxicity. SBRT may be beneficial in elderly patients with early-stage NSCLC.

Abstract
PURPOSE To examine the effect of the attachment features (abutment height, retention, and freedom of rotation) of implant overdentures on the bending strain around implants under an overdenture. MATERIALS AND METHODS Mandibular and maxillary edentulous models were fabricated and covered with silicone rubber. Strain gauges were attached to the four sides of each implant. Two implants (tissue-level implant, 4.1-mm diameter, 10-mm length) were placed bilaterally in the area between the mandibular canines and lateral incisors. A maxillary conventional denture and a mandibular overdenture were made to fit the edentulous models. Three levels of peri-implant bone resorption were created sequentially: no bone resorption, 0.8 mm, and 1.5 mm. Three kinds of attachments (magnetic, stud, and ball attachments) were used. Bending strains generated from a 98-N occlusal load through the maxillary denture were measured using a sensor interface, and the data were analyzed using the Kruskal-Wallis and Bonferroni tests. Multiple regression analysis was used to find the relationship between independent variables (peri-implant bone resorption level, abutment height, retention, and freedom of rotation) and the dependent variable (bending strain). RESULTS For all attachment types, the bending strains were smallest with no bone resorption and largest with 1.5-mm bone resorption (P < .05). Multiple regression analysis showed that abutment height had the greatest impact on the reduction of bending strain (beta = .413), followed by freedom of rotation (beta = -.349), and retention (beta = .107). CONCLUSION Low abutment height, large freedom of rotation, and low retention can minimize bending strain around implants.

Abstract
A male neonate presented with the aortic/mitral stenotic variant of hypoplastic left heart syndrome, wherein the suprasystemic left ventricular pressure and relatively large left ventricle had shifted the intraventricular septum. Despite bilateral pulmonary artery banding, the stroke volume was difficult to maintain owing to the compressed right ventricle, causing heart failure symptoms. Percutaneous balloon aortic valvuloplasty decreased the left ventricular pressure, restoring the right ventricular function. Norwood procedure with mitral valve closure after catheter intervention reduced the left ventricular size and improved the right ventricular function. This paper refers to the potential of mitral valve closure for hypoplastic left heart syndrome.

Abstract
As HLA haploidentical related donors are quickly available, HLA
haploidentical hematopoietic stem cell transplantation (haploHSCT) using high-dose
post-transplant cyclophosphamide (PTCy) is now widely used. Recent basic and
clinical studies revealed the details of immune reconstitution after T-cell replete
haploHSCT using PTCy. T cells and NK cells in the graft proliferate abundantly at day 3
post-haploHSCT, and the PTCy eliminates these proliferating cells. After ablation of
proliferating mature cells, donor-derived NK cell reconstitution occurs after the second
week; however, recovering NK cells remain functionally impaired for at least several
months after haploHSCT. PTCy depletes proliferating cells, resulting in the preferential
accumulation of Treg and CD4+ T cells, especially the memory stem T cell
(TSCM) phenotype. TSCM capable of both
self-renewal and differentiation into effector T cells may play an important role in the
first month of immune reconstitution. Subsequently, de novo T cells
progressively recover but their levels remain well below those of donor CD4+ T cells at
the first year after haploHSCT. The phenotype of recovering T cells after HSCT is
predominantly effector memory, whereas B cells are predominantly phenotypically naive
throughout the first year after haploHSCT. B cell recovery depends on de
novo generation and they are not detected until week 4 after haploHSCT. At week
5, recovering B cells mostly exhibit an unconventional transitional cell phenotype and the
cell subset undergoes maturation. Recent advances in immune reconstitution have improved
our understanding of the relationship between haploHSCT with PTCy and the clinical
outcome.

Abstract
We evaluated the application of in vivo tissue-engineered vascular graft (in vivo TEVG) in pulmonary artery (PA) reconstruction as a substitute for autologous pericardium. From July 2017 to April 2020, 4 patients (male:female = 2:2) with major aortopulmonary collateral arteries underwent PA reconstruction with in vivo TEVGs. Graft moulds were embedded into the subcutaneous spaces in the first palliative surgery. In the second surgery used in vivo TEVGs were used as patch materials to treat PA stenosis. Preoperative and postoperative PA configurations were evaluated by computed tomography. Patients' median age and body weight were 1.6 (1-4) years and 8.7 (7.3-15.4) kg, respectively. Two patients underwent PA reconstruction during staged repair and 2 underwent reconstruction during definitive repair. One patient had postoperative PA restenosis due to bronchial compression; re-PA reconstruction with in vivo TEVGs was performed. On histological examination, the in vivo TEVG wall mainly comprised collagen fibres and a small number of fibroblasts. The midterm results of this technique are satisfactory. in vivo TEVGs could be a promising alternative to autologous pericardium for paediatric cardiovascular surgeries requiring multi-stage operations.

Abstract
Injection of lymphokine activated killer (LAK) cells is known as useful for activation of cellular immune system. Although the effect of LAK cells has been clarified in human or mice, this effect on function of immune cells has not been examined in calves. Healthy ten Holstein calves were injected with the LAK cells 2 days after birth (LAK Group), and another eight calves were observed as controls (Control Group). All calves received the colostrum formulation on the day of birth, and then, were inoculated with a live attenuated vaccine of bovine herpesvirus (BHV)-1 at 2 (the first vaccination) and 6 (the second vaccination) weeks after birth. Peripheral blood of their dam obtained 3 weeks before calving was used for preparation of LAK cells. Blood samples were taken prior to vaccine inoculation and 3 days after the first inoculation, as well as 3 and 6 days after the second vaccination from all calves. Numbers of CD8+ and CD21+ cells increased significantly after the second vaccination in the LAK Group compared with Control Group. The present study suggested the improved effect of injecting LAK cells originated from dams on immune cells function of young calves after BHV-1 live vaccine.

Abstract
BACKGROUND The relationship between uneven occlusal contact and fall risk has been described in elderly participants; however, multiple confounding factors, such as systemic disease or deterioration in vestibular function, have not been well considered. This study aimed to investigate this relationship in pediatric participants at the age of approximately 9-12, where these confounding factors are absent and the replacement of primary molars by permanent ones generally occurs and transiently results in uneven occlusal contact. METHODS Sixty-five children (36 boys and 29 girls, mean age: 9.5 ± 1.5 years) were enrolled in this study. Participants were asked whether they had experienced at least two falls within the past 1 year. The occlusal contact area ratio was calculated by dividing the greater half (right or left dental arch) by the smaller half (the other half) with U-shaped pressure sensor sheet. The total length and rectangular area of the center of pressure while standing upright for 10 s were measured with a stabilometer and used as postural sway parameters. RESULTS The occlusal contact area ratio significantly correlated with the postural sway parameters. Comparison between those who had experienced the fall incidences and those who had not after propensity score matching that adjusts their overall physical function revealed that there were no significant differences in the postural sway parameters and occlusal contact area ratio regardless of the history of fall incidence. CONCLUSIONS Uneven occlusal contact leads to an increase in postural sway in children; however, this may not be associated with fall incidence.

Abstract
To overcome the delayed or failed engraftment after unrelated cord blood transplantation (CBT), we conducted a multicenter phase II study of intrabone single-unit CBT without antithymocyte globulin (ATG) for adult patients with hematological malignancies (UMIN-CTR, UMIN000020997). Sixty-four patients received an intrabone injection of unwashed (n = 61) or washed (n = 3) cord blood after local anesthesia. All injection-related adverse events were mild and resolved spontaneously. Sixty-two patients were evaluable for the efficacy of intrabone CBT of serological HLA-A, -B, and -DR ≥ 4/6 matched cord blood with a median number of 2.57 × 107/kg cryopreserved total nucleated cells. The probability of survival with neutrophil engraftment on day 28 was 77.4% (95% confidence interval, 67.0-85.8%), which exceeded the threshold value. The cumulative incidences of neutrophils ≥ 0.5 × 109/L on day 60 was 80.6% (68.2-88.6%), with a median time to recovery of 21 days after transplantation. The cumulative incidences of platelets ≥ 20 × 109/L and platelets ≥ 50 × 109/L on day 100 were 75.8% (62.6-84.9%) and 72.6% (59.4-82.1%), respectively, with median time to platelets ≥ 20 × 109/L and platelets ≥ 50 × 109/L of 38 and 45 days after transplantation, respectively. The cumulative incidences of grade II-IV and III-IV acute graft-versus-host disease were 29.0% and 6.5%, respectively. All responded to steroid therapy, and secondary treatments were not required. The present study suggests the efficacy of intrabone single-unit CBT without ATG in terms of early engraftment and controllable acute graft-versus-host disease.

Abstract
BACKGROUND While duodenal ulcer (DU) and gastric cancer (GC) are both H. pylori infection-related diseases, individuals with DU are known to have lower risk for GC. Many epidemiological studies have identified the PSCA rs2294008 T-allele as a risk factor of GC, while others have found an association between the rs2294008 C-allele and risk of DU and gastric ulcer (GU). Following these initial reports, however, few studies have since validated these associations. Here, we aimed to validate the association between variations in PSCA and the risk of DU/GU and evaluate its interaction with environmental factors in a Japanese population. METHODS Six PSCA SNPs were genotyped in 584 DU cases, 925 GU cases, and 8,105 controls from the Japan Multi-Institutional Collaborative Cohort (J-MICC). Unconditional logistic regression models were applied to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the association between the SNPs and risk of DU/GU. RESULTS PSCA rs2294008 C-allele was associated with per allele OR of 1.34 (95% CI, 1.18-1.51; P = 2.28 × 10-6) for the risk of DU. This association was independent of age, sex, study site, smoking habit, drinking habit, and H. pylori status. On the other hand, we did not observe an association between the risk of GU and PSCA SNPs. CONCLUSIONS Our study confirms an association between the PSCA rs2294008 C-allele and the risk of DU in a Japanese population.

Abstract
PURPOSE Whether it is possible to prevent mechanical stress on teeth via an occlusal splint remains to be clarified. This study aimed to assess the same by simultaneously recording the occlusal pressure and strain on the teeth in humans. METHODS Eleven participants (five women and six men; mean age 25.7 years) were enrolled in this study. Hard and soft oral appliances were fabricated for the maxillary arch of each participant. The strain on the four target teeth (right maxillary and mandibular first premolars, and first molars) and occlusal pressure were concurrently measured, while the participants performed maximum voluntary teeth clenching under each condition (hard, soft, or no occlusal splint). RESULTS Compared to the absence of an occlusal splint, hard occlusal splints generated less strain on molar teeth but more strain on premolar teeth, while soft occlusal splints did not lower the strain on all target teeth significantly. CONCLUSION Considering the limitations of this study, hard occlusal splints should be used for the protection of molar teeth but for premolar teeth caution is required and depends on the case. On the other hand, soft occlusal splints may not have any benefit for the protection of either type of teeth for patients exhibiting excessive occlusal pressure.

Abstract
OBJECTIVES Clinical evidence demonstrating the effectiveness of implants in preventing tooth loss is limited because of the many risk factors involved in tooth loss. This retrospective cohort study investigated whether an implant in the molar region of a distal free-end edentulous space affects the loss of the most distal tooth after 6 years, adjusting for other risk factors associated with tooth loss using propensity score matching analysis. MATERIAL AND METHODS A total of 571 subjects and 1,085 teeth adjacent to a distal free-end edentulous space were evaluated. At baseline, the 1,085 teeth were divided into two groups according to the presence or absence of a molar implant with a fixed dental prosthesis in the distal free-end edentulous space. Propensity score matching analysis was used to reduce the effects of bias by matching teeth with and without implants according to similar background factors at baseline. The adjusted variables were age group, occlusal support status, Kennedy classification, tooth position, tooth type, restoration status, dental caries, periodontal pocket depth, and condition of the opposing tooth. RESULTS A total of 56 teeth (28 associated with a molar implant; 28 with no implant) were enrolled according to propensity score matching. Fisher's exact test showed that a molar implant significantly protected the tooth adjacent to the distal free-end edentulous space (p = .01). CONCLUSIONS Within the limitations of this retrospective cohort study, it was found that implants in free-end edentulous spaces may be beneficial in extending the longevity of adjacent teeth. Further research will be necessary to confirm this finding.

Abstract
The formation of a dineutron in the ^{11}Li nucleus is found to be localized to the surface region. The experiment measured the intrinsic momentum of the struck neutron in ^{11}Li via the (p,pn) knockout reaction at 246 MeV/nucleon. The correlation angle between the two neutrons is, for the first time, measured as a function of the intrinsic neutron momentum. A comparison with reaction calculations reveals the localization of the dineutron at r∼3.6 fm. The results also support the density dependence of dineutron formation as deduced from Hartree-Fock-Bogoliubov calculations for nuclear matter.

Abstract
OBJECTIVES Immune checkpoint inhibitors offer longer survival than chemotherapy in several clinical trials for advanced non-small cell lung cancer. In subset analyses of clinical trials, immune checkpoint inhibitors extended survival in patients aged ≥65 years, but the effects in patients aged ≥75 years are controversial. We performed multicenter, collaborative and retrospective analyses of immune checkpoint inhibitor efficacy and safety in non-small cell lung cancer patients aged ≥75 years. METHODS We retrospectively studied 434 advanced non-small cell lung cancer patients who received immune checkpoint inhibitors from December 2015 to December 2017, and retrospectively applied the Geriatric (G) 8 screening tool with medical records. RESULTS Of the 434 patients who received immune checkpoint inhibitors, 100 were aged ≥75 years. Five patients with performance status 3 were omitted from the final analysis. Immune checkpoint inhibitors were given as a first-line treatment to 20 patients. The objective response rates, median progression-free survival rates and median survival times were 35.0%, 6.1 months and 10.7 months for first-line treatment, and 20.0%, 2.9 months and 14.7 months for second- or later-line treatments, respectively. The median modified G8 score was 11.0. The median survival time was longer in the high modified G8 (≥12.0) group than in the low modified G8 (≤11.0) group (18.7 vs. 8.7 months; P = 0.02). Likewise, the median survival time was 15.5 months (performance status 0-1) vs. 3.2 months (performance status 2) (P < 0.01). The grade ≥ 2 immune-related adverse events incidence was 36.8%. CONCLUSIONS In this study, immune checkpoint inhibitors were effective and tolerable for patients aged ≥75 years. The modified G8 screening tool and performance status were associated with the outcome of older non-small cell lung cancer patients treated with immune checkpoint inhibitors.

Abstract
Background: The clinical usefulness of concurrent chemoradiotherapy before surgery in the treatment of primary, locally advanced sinonasal low-grade, non-intestinal type adenocarcinoma (LG non-ITAC) is unclear. Methods: We present the first case report of the efficacy of super-selective intra-arterial cisplatin (CDDP) infusion concurrent with conventional fractionated radiotherapy (RT) for LG non-ITAC in a Japanese patient. Results: A white, rugged-marginal mass that was histopathologically diagnosed as LG non-ITAC occupied the right nasal cavity. Based on the imaging findings, including computed tomography, magnetic resonance imaging, and positron emission tomography, the tumor was diagnosed as T4aN0M0, stage IVa. After treatment, the nasal tumor disappeared leaving only a small bulge in the medial wall of the middle turbinate. The patient also underwent right transnasal ethmoidectomy performed as salvage surgery. A histopathological examination revealed that the lesion was replaced by granulation tissue with lymphocytic infiltration and hemosiderin-laden macrophages, and no viable tumor cells remained. In the seven years after treatment, the patient has not experienced any local recurrence or regional or distant metastasis. Conclusions: Super-selective intra-arterial CDDP infusion concurrent with conventional fractionated RT followed by salvage surgery might be useful for the management of sinonasal LG non-ITAC.

Abstract
OBJECTIVES In Japan, homograft and bovine jugular vein are available in very limited institutions for the reconstruction of the right ventricular outflow tract, and handmade expanded polytetrafluoroethylene (ePTFE)-valved conduits have been widely used instead. This study aimed to clarify the long-term outcomes and the durability of the ePTFE-valved conduits purely by narrowing down to those with large sizes to eliminate the influence of the body growth. METHODS Between January 2002 and December 2015, patients who underwent right ventricular outflow tract reconstruction in 34 Japanese institutions using ePTFE-valved conduits with a diameter of ≥18 mm were included. All the valved conduits were made in the authors' institution and delivered to each participating institution. RESULTS Overall, 502 patients were included. Early mortality was 1.4% and not related to conduit failure. The overall survival rate was 98.2% at 5 years and 96.6% at 10 years. Freedom from conduit explantation was 99.5% at 5 years and 89.0% at 10 years. Three patients (0.13 per 100 patient-years) developed infective endocarditis of the conduit, and only 1 patient required conduit removal. Pulmonary insufficiency was mild or less in 480 (96%) patients, and conduit stenosis was mild or less in 436 (88%) patients at the latest follow-up. CONCLUSIONS By narrowing the analyses down to only ePTFE conduits with a large size, satisfactory long-term outcomes of these conduits with a fan-shaped valve and bulging sinuses were shown. These conduits would be among the optimal choices for right ventricular outflow tract reconstruction.

Abstract
The detection of certain oncogenic driver mutations, including those of epidermal growth factor receptor (EGFR), is essential for determining treatment strategies for advanced non-small cell lung cancer (NSCLC). The current study assessed the feasibility of testing exhaled breath condensate (EBC) for EGFR mutations by droplet digital PCR (ddPCR). Samples were collected from 12 patients with NSCLC harboring EGFR mutations that were admitted to Okayama University Hospital between June 1, 2014 and December 31, 2017. A total of 21 EBC samples were collected using the RTube™ method and EGFR mutations (L858R, exon 19 deletions or T790M) were assessed through ddPCR analysis (EBC-ddPCR). A total of 3 healthy volunteer samples were also tested to determine a threshold value for each mutation. Various patient characteristics were determined, including sex (3 males and 9 females), age (range 54-81 years; median, 66 years), smoking history (10 had never smoked; 2 were former smokers), histology (12 patients exhibited adenocarcinoma), clinical stage (9 patients were stage IV; 3 exhibited post-operative recurrence) and EGFR mutation type (4 had L858R; 8 had exon 19 deletions; 8 had T790M). EBC-ddPCR demonstrated positive droplets in 8 of the 12 patients. The sensitivity and specificity of each mutation was as follows: 27.3 and 80.0% for EGFR L858R, 30.0 and 90.9% for EGFR Ex19del, and 22.2 and 100% for EGFR T790M. EBC-ddPCR analysis of EGFR mutations exhibited modest sensitivity and acceptable specificity. EBC-ddPCR is a minimally invasive and replicable procedure and may be a complementary method for EGFR testing in patients where blood or tissue sampling proves difficult.

Abstract
Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) is the standard therapy for non-small cell lung cancer (NSCLC) harboring EGFR mutations, but the resistance is inevitable. The drug-tolerant persister cancer cells are thought to be involved in the resistance. We recently reported that HER2 expression had a negative impact on time-to-treatment-failure in patients with EGFR mutant NSCLC. In this study, we hypothesized that HER2 might be a potential target for alternative combination therapy in NSCLC harboring EGFR mutations. In vitro study showed that the level of HER2 expression had no correlation with the sensitivity to EGFR-TKI, erlotinib but showed some correlation with HER2-inhibitor, ado-trastuzumab emtansine (T-DM1) in multiple EGFR-mutant lung cancer cell lines. In addition, HER2 expression was increased in persister cancer cells in 11-18 cell line harboring EGFR L858R or HCC827 cell line harboring EGFR exon 19 deletion after the exposure to erlotinib in vitro and in vivo. The combination of erlotinib and T-DM1 showed a superior inhibitory effect on cell proliferation compared with those of the erlotinib or T-DM1 alone in either 11-18 or HCC827 cells in vitro. The combination therapy also induced a significantly greater inhibitory effect on tumor growth in xenograft model in mice transplanted with either 11-18 or HCC827 cells compared with erlotinib alone or T-DM1 alone. No body weight loss was observed in these mice. These results suggested that the combination therapy with EGFR-TKI and T-DM1 might be a potentially promising strategy for treating lung cancer harboring EGFR mutations.

Abstract
Periodontal disease and arteriosclerotic disease are greatly affected by aging. In this study, the association of conventional risk factors and periodontal disease with atherosclerosis was longitudinally examined in Japanese older adults. Subjects in this study were 490 community-dwelling septuagenarians (69-71 years) randomly recruited from the Basic Resident Registry of urban or rural areas in Japan. At the baseline examination, all subjects underwent socioeconomic and medical interviews; medical examinations, including examinations for carotid atherosclerosis, hypertension, diabetes mellitus, and dyslipidemia; and conventional dental examinations, including a tooth count and measurement of probing pocket depth (PPD). After 3 years, 182 septuagenarians who had no atherosclerosis at the baseline examination were registered and received the same examination as at the baseline. In the re-examination conducted 3 years after the baseline survey, 131 (72.0%) of the 182 participants who had no atherosclerosis at the baseline examination were diagnosed with carotid atherosclerosis. Adjusting and analyzing the mutual relationships of the conventional risk factors for atherosclerosis by multiple logistic regression analysis for the 171 septuagenarians with a full set of data, the proportion of teeth with PPD ≥ 4 mm was independently related to the prevalence of atherosclerosis (odds ratio: 1.029, P < 0.022). This longitudinal study of Japanese older adults suggests that periodontal disease is associated with the onset/progression of atherosclerosis. Maintaining a healthy periodontal condition may be an important factor in preventing the development and progression of atherosclerosis.

Abstract
Breast involvement of Adult T-cell leukemia-lymphoma (ATLL) is extremely rare, and the data on the characteristics are limited. We herein describe a 49-year-old woman who presented with skin involvement of ATLL. Positron emission tomography/computed tomography showed bilateral breast lesions. Although the patient once achieved a complete metabolic response, a relapse of her ATLL occurred. The patient received subsequent allogeneic hematopoietic stem cell transplantation (HSCT). To our knowledge, only four cases of ATLL with breast involvement have previously been reported, and the prognoses have generally been poor. Breast lesions of ATLL have aggressive features, and intensive systemic chemotherapy and HSCT are required to improve survival.

Abstract
A prodrug of levofloxacin (LVFX), cilexetil ester of LVFX (LVFX-CLX), was synthesized to examine whether the prodrug can avoid chelate formation with metal cations in the gastrointestinal tract. LVFX-CLX exhibited a 10-times higher partition coefficient than LVFX. In vitro, LVFX was precipitated by 76.1% in the presence of a 10-times higher concentration of aluminium chloride (Al3+), but LVFX-CLX was not. LVFX-CLX was rapidly hydrolyzed enzymatically by rat plasma, intestinal mucosal and liver homogenates at 37 °C, but not by pancreatic enzymes and luminal fluid. The minimum inhibitory concentration values of LVFX-CLX against S. aureus, E. coli and P. aeruginosa were far higher than that of LVFX. In rats, area under the plasma concentration-time curve from zero to 4 h (AUC0-4h) of LVFX after oral administration of LVFX-CLX was 1.34-fold higher than that after LVFX, though it did not reach significance level. Co-administration of Al3+ with LVFX and LVFX-CLX in rats decreased AUC0-4h of plasma LVFX by 75% and 60%, respectively, however, the AUC0-4h of plasma LVFX after co-administration of LVFX-CLX and Al3+ was 2.2-times higher than that after co-administration of LVFX and Al3+. These results suggested that the use of LVFX-CLX may reduce the modulation of intestinal microflora caused by LVFX and the suppressive effect of Al3+ on intestinal absorption of LVFX.

Abstract
The prognosis of advanced non-small cell lung cancer (NSCLC) patients has improved in recent decades, especially for patients with an oncogenic driver mutation. Anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitors (TKIs) are effective for patients with the echinoderm microtubule-associated protein-like 4-ALK fusion gene. Several ALK-TKIs have been established: the first-generation ALK-TKI, crizotinib; second-generation ALK-TKIs, alectinib and ceritinib; and third-generation ALK-TKI, lorlatinib. Some ALK-TKIs are effective for tumors that are resistant to other ALK-TKIs; however, as is known in epidermal growth factor receptormutant lung cancer, tumor resistance is inevitable. ALK-positive NSCLCs acquire resistance via various mechanisms, making it a heterogeneous disease. Therefore, it is necessary to develop next-generation treatment strategies, such as the use of next-generation ALK-TKIs for secondary mutations, or combination therapies with ALK-TKIs and other TKIs. In this review, we summarize the development and use of ALK-TKIs, prior pivotal clinical trials, and resistance mechanisms.

Abstract
BACKGROUND Worldwide, there has been a growing interest in oncofertility issues. In 2017, the Japanese Society of Clinical Oncology published clinical practice guidelines for fertility preservation (FP) in cancer patients. We conducted a questionnaire survey to explore the FP practices among hematologists before the publication of this guideline. METHODS We sent 427 designated cancer hospitals in Japan a questionnaire about FP treatment for patients with hematological malignancies between January and December 2014. RESULTS Of these, 137 institutions responded, and 81 (19.0%) were included in the analysis. A total of 324 female and 441 male patients, aged < 40 years, were treated. The percentage of patients informed about FP was higher in patients treated with hematopoietic cell transplant than those without. Female patients were less likely to be informed about FP than male patients. FP was performed in a total of 27 female patients: 20 oocyte cryopreservation, 2 embryo cryopreservation, 3 ovarian tissue cryopreservation, and 2 ovarian shielding during total body irradiation. Sperm cryopreservation was performed in 115 male patients. CONCLUSIONS Our findings indicate the reality of fertility preservation in 2014, before the guideline were issued. Further studies are warranted to investigate the improvement in fertility preservation since the guidelines were issued.

Abstract
We present a search for the direct production of a light pseudoscalar a decaying into two photons with the Belle II detector at the SuperKEKB collider. We search for the process e^{+}e^{-}→γa, a→γγ in the mass range 0.2<m_{a}<9.7 GeV/c^{2} using data corresponding to an integrated luminosity of (445±3) pb^{-1}. Light pseudoscalars interacting predominantly with standard model gauge bosons (so-called axionlike particles or ALPs) are frequently postulated in extensions of the standard model. We find no evidence for ALPs and set 95% confidence level upper limits on the coupling strength g_{aγγ} of ALPs to photons at the level of 10^{-3} GeV^{-1}. The limits are the most restrictive to date for 0.2<m_{a}<1 GeV/c^{2}.

Abstract
Photodynamic therapy (PDT) is an emerging treatment for various solid cancers. We recently reported that tumor cell lines and patient specimens from adult T cell leukemia/lymphoma (ATL) are susceptible to specific cell death by visible light exposure after a short-term culture with 5-aminolevulinic acid, indicating that extracorporeal photopheresis could eradicate hematological tumor cells circulating in peripheral blood. As a bridge from basic research to clinical trial of PDT for hematological malignancies, we here examined the efficacy of ALA-PDT on various lymphoid malignancies with circulating tumor cells in peripheral blood. We also examined the effects of ALA-PDT on tumor cells before and after conventional chemotherapy. With 16 primary blood samples from 13 patients, we demonstrated that PDT efficiently killed tumor cells without influencing normal lymphocytes in aggressive diseases such as acute ATL. Importantly, PDT could eradicate acute ATL cells remaining after standard chemotherapy or anti-CCR4 antibody, suggesting that PDT could work together with other conventional therapies in a complementary manner. The responses of PDT on indolent tumor cells were various but were clearly depending on accumulation of protoporphyrin IX, which indicates the possibility of biomarker-guided application of PDT. These findings provide important information for developing novel therapeutic strategy for hematological malignancies.

Abstract
Bendamustine and rituximab (BR) are widely used in patients with follicular lymphoma (FL) previously treated with conventional immunochemotherapy, but the role of consolidation radioimmunotherapy in these patients is unknown. This study evaluated the efficacy and safety of consolidation with 90 Yttrium-ibritumomab tiuxetan (90 Y-IT) after re-induction therapy with BR in patients with previously treated FL. This study included adult patients with relapsed FL who had undergone one or two prior therapies. Re-induction therapy with BR was administered every 4 weeks up to 4-6 cycles. If patients achieved at least partial response, 90 Y-IT was administered as consolidation therapy. The primary endpoint was 2-year progression-free survival (PFS) after consolidation. A total of 24 FL patients (median age 60 years) who had undergone one (n = 17) or two (n = 7) prior treatments received BR. After BR therapy, 22 patients proceeded to consolidation with 90 Y-IT, resulting in an overall 88% response rate to the protocol treatment. Within a median observation period of 46.8 months, the estimated 2-year PFS rate after the consolidation among the 22 patients receiving 90 Y-IT was 59% (95% confidence interval [CI], 38%-77%). Patients whose remission after previous treatment had lasted ≥2 years had a significantly higher 2-year PFS rate than patients whose remission after previous treatment had been <2 years (68% vs. 33%, Wilcoxon p = 0.0211). Major adverse events during the protocol treatment and within 2 years after the consolidation were hematological toxicities, but they were generally acceptable. Consequently, the estimated 2-year overall survival after the consolidation was 95% (95% CI, 74%-99%). In conclusion, in a subset of patients with previously treated FL, 90 Y-IT consolidation after BR re-induction conferred a durable remission, indicating that consolidation therapy using 90 Y-IT may be a novel therapeutic option for patients with relapsed FL (UMIN000008793).

Abstract
OBJECTIVE In this study, we aimed to retrospectively investigate and confirm whether atypical nuclear findings in endometrial cytology are useful when assessed by image morphometry in liquid-based cytology (LBC) and compared with microscopic evaluation. METHODS In total, 53 cases were selected for this study, including 11 presenting proliferative endometrium, 12 with surface papillary syncytial change with endometrial glandular and stromal breakdown (EGBD-SPSC), 10 endometrioid carcinoma grade 1 (G1-EEC), 10 EEC grade 3 (G3-EEC), and 10 endometrial serous carcinomas (ESC). Nuclear image morphometry for nuclear geometric features (area, grey value, aspect ratio, internuclear distance, nucleolar diameter) was performed using ImageJ computer software. For assessing nucleoli, 3861 nuclei were measured, and for nuclear findings, except for nucleoli, 4036 nuclei were measured in total. RESULTS (a) Compared with G1-EEC, G3-EEC and ESC presented a marked increase in all six parameters (nuclear enlargement, anisonucleosis, nuclear shade, nuclear shape, irregularity of nuclear arrangement, and nucleolar size). (b) EGBD-SPSC presented a marked increase in two parameters (nuclear shade, nuclear shape) when compared with G1/G3-EEC and ESC. (c) Compared with EGBD-SPSC, EEC and ESC demonstrated a marked increase in nucleolar size (≥2.0 μm). (d) ESC presented a marked increase in nucleolar size (≥3.0 μm) when compared with G3-EEC. CONCLUSIONS Here we confirmed that atypical nuclear findings evaluated by image morphometry are as useful as microscopic evaluations in endometrial cytology. We believe that the objective evaluation of nucleolar size could contribute to an accurate diagnosis of endometrial-LBC samples.

Abstract
PURPOSE The purpose of this study was to evaluate the occlusal force adjusting ability of implant-supported overdenture (IOD) wearers, as compared with natural teeth and complete dentures. METHODS Subjects were those with natural dentition (ND group; 19 subjects), those with implant-supported overdentures (IOD group; 7 subjects), and those with complete dentures (CD group; 14 subjects). Subjects were asked to hold test foods (peanuts and biscuits mounted on a custom-made apparatus with a force transducer) between their anterior incisors (hold phase) and split test foods (split phase). The mean value of the occlusal force during the hold phase (hold force), the peak force rate during the split phase (peak force rate), the time required to split test foods (duration), and the maximum occlusal force in the split phase (split force) were selected as outcomes. Data were analyzed with Wilcoxon's signed rank test, the Kruskal-Wallis test, and multiple regression analysis (Statistical significance levels: 5%). RESULTS For peanuts, the peak force rate for the ND group was significantly higher than the IOD and CD groups. The duration of the CD group was significantly longer than the ND and IOD groups. Multiple regression analysis indicated that even with adjustment for age and sex, there were significant differences in the peak force rate between the ND and the IOD, CD groups, and in the duration between the ND and CD group. CONCLUSIONS Subjects with IODs showed superior ability to adjust occlusal force, as compared with complete dentures, although it didn't match the natural dentition.

Abstract
AIM Evidence is lacking on the best standard method for forced diuresis to prevent cisplatin-induced nephrotoxicity. We compared the cisplatin-induced nephrotoxicity prevention effect of furosemide or mannitol in patients with advanced non-small cell lung cancer. METHODS Patients with advanced non-small cell lung cancer suitable to receive cisplatin-containing regimen were randomly assigned to receive furosemide or mannitol with appropriate hydration. The primary endpoint was the proportion of ≥ grade 1 serum creatinine elevation in the first cycle. RESULTS The trial was terminated early with 44 (22 per arm) of the planned 66 patients because of slow accrual. Patients' characteristics were well balanced with median baseline creatinine clearance of 98.0 and 95.1 mL/min in the furosemide and mannitol arms, respectively. In the first cycle, two (9%) and four (18%) patients developed grade 1 creatinine elevation (P = .66), respectively, despite no ≥ grade 2 toxicity. The median times to develop the worst creatinine score were 10 and 8 days, respectively. For all cycles, median times to recover to grade 0 were 56 and 20 days, respectively. The furosemide arm was characterized by relatively high urine output after cisplatin administration (900 vs 550 mL/h), low frequency of unplanned additional hydration (14% vs 32%), and high incidence of hyponatremia (18% and 5%) compared with the mannitol arm. Both arms showed similar progression-free survival and overall survival. CONCLUSION The preventive effect of the two forced diuretics on cisplatin-induced nephrotoxicity was not significantly different. However, the two diuretics have some distinct types of clinical presentations.

Abstract
This European Society of Coloproctology guidance focuses on a proposed conceptual framework to resume standard service in colorectal surgery. The proposed conceptual framework is a schematic and stepwise approach including: in-depth assessment of damage to non-COVID-19-related colorectal service; the return of service (integration with the COVID-19-specific service and the existing operational continuity planning); safety arrangements in parallel with minimizing downtime; the required support for staff and patients; the aftermath of the pandemic and continued strategic planning. This will be dynamic guidance with ongoing updates using critical appraisal of emerging evidence. We will welcome input from all stakeholders (statutory organizations, healthcare professionals, public and patients). Any new questions, new data and discussion are welcome via https://www.escp.eu.com/guidelines.

Abstract
BACKGROUND Nintedanib is a multi-kinase inhibitor approved for idiopathic pulmonary fibrosis (IPF); however, its efficacy and safety for patients with IPF and restricted pulmonary function remain unclear. Therefore, the objective of this study was to determine the efficacy and safety of nintedanib for patients with IPF and forced vital capacity (FVC) ≤ 50%. METHODS This was a multi-center retrospective study performed by the Okayama Respiratory Disease Study Group. Patients were allocated into FVC ≤ 50% and FVC > 50% groups based on their predicted FVC. The primary endpoints were FVC changes from baseline after 6 and 12 months. RESULTS 45 patients were eligible for the study. 18 patients had FVC ≤ 50%, and 27 patients had FVC > 50%. Overall, 31 and 19 patients underwent pulmonary function tests at 6 and 12 months after initiating nintedanib, respectively. FVC changes from baseline at 6 and 12 months after initiating nintedanib were comparable between the two groups. Adverse events were seen in all patients, and the rates of patients who discontinued nintedanib were also comparable (38.9% vs. 37.0%, p = 1.000). Multiple regression analysis showed that age and forced expiratory volume in 1 second (FEV1)/FVC were negatively correlated with changes in FVC at 6 months after initiating nintedanib. CONCLUSIONS Our data suggest that nintedanib can be a useful agent for IPF patients, including those with a low FVC, and that age and FEV1/FVC are predictive markers for changes in FVC following nintedanib treatment.

Abstract
Most clinical trials of non‐small‐cell lung cancer (NSCLC) exclude patients with poor ECOG performance status (PS). Thus, the efficacy of immune checkpoint inhibitors (ICIs) in patients with poor PS remains unclear. Herein, we used data from a retrospective cohort to assess the potential clinical benefits of ICIs in NSCLC patients with poor PS. Data from NSCLC patients who received ICI monotherapy at 9 institutions between December 2015 and May 2018 were retrospectively analyzed. After excluding 4 patients who lacked PS data, a total of 527 ICI‐treated patients, including 79 patients with PS 2 or higher, were used for our analyses. The progression‐free survival (PFS) and overall survival (OS) of patients with PS 2 or higher were significantly shorter compared with those of PS 0‐1 patients (median PFS, 4.1 vs 2.0 months; P < .001 and median OS, 17.4 vs 4.0 months; P < .001). Among NSCLC patients with programmed cell death protein‐ligand 1 (PD‐L1) expression of 50% or higher who were treated with pembrolizumab as first‐line therapy, the median PFS times of patients with PS 2 and 0‐1 were 7.3 and 8.1 months, respectively. There was no significant difference in PFS between patients with PS 2 and 0‐1 (P = .321). Although poor PS was significantly associated with worse outcomes in NSCLC patients treated with ICIs, pembrolizumab as a first‐line treatment in NSCLC patients expressing high levels of PD‐L1 could provide a clinical benefit, even in patients with PS 2.

Abstract
Hematological diseases after solid organ transplant (SOT) are an emerging issue as the number of long-term SOT survivors increases. Expertise in managing patients requiring allogeneic hematopoietic stem cell transplantation (HSCT) after SOT from independent donors is needed; however, clinical reports of HSCT after SOT are limited, and the feasibility and risk are not well understood. In particular, HSCT in prior lung transplant recipients is thought to be complicated as the lung is immunologically distinct and is constantly exposed to the surrounding environment. Herein, we describe a case of successful HSCT in a patient with myelodysplastic syndromes who had previously received a lung transplant from a deceased donor for bronchiolitis obliterans syndrome. Reports about cases of HSCT after lung transplant are quite rare; thus, we discuss the mechanisms of immune tolerance through the clinical course of our case. This case suggests that HSCT after SOT can be considered a therapeutic option in cases where the transplanted organ is functionally retained and the hematological disease is in remission.

Abstract
Pulmonary alveolar proteinosis (PAP) is an uncommon lung disorder characterized by the excessive accumulation of surfactant-derived lipoproteins in the pulmonary alveoli and terminal bronchiole. Secondary PAP associated with primary myelofibrosis (PMF) is extremely rare, and to our knowledge, no autopsy case has been reported. We herein report an autopsy case of secondary PAP occurring in a patient with PMF who was treated with the Janus kinase 1/2 inhibitor ruxolitinib. We confirmed a diagnosis of PAP with complications based on the pathological findings at the autopsy. Notably, this case might suggest an association between ruxolitinib treatment and PAP occurrence.

Abstract
IgG4-producing marginal zone B-cell lymphomas (MZLs) have been recently proposed as a subtype of MZLs. Despite the abundant literature on pathophysiological features of this type of lymphoma, only a few retrospective studies pertaining to the treatment outcomes have been reported, and its prognosis remains unclear. We retrospectively analyzed seven patients with IgG4-producing MZLs diagnosed at our institute, with specific reference to treatment and outcomes. The median age was 69.0 years (55-79), and all were males. The median follow-up period was 66.6 months (8-121). All patients had localized disease; four patients had tumors of the ocular adnexa, whereas two had retroperitoneal tumors. Five patients were treated with irradiation (30 Gy/15 fr) (n = 4) or surgery (n = 1), resulting in tumor reduction. Two patients were treated by chemotherapy or irradiation. Among them, one commenced rituximab monotherapy, which led to an inadequate reduction of the tumor. Subsequent irradiation induced complete response (CR). The other patient experienced repeated relapses during follow-up and finally achieved CR by combination chemotherapy. Treatment was well tolerated in all cases, and none of the patients showed disease progression at the last follow-up visit. Our results indicate that the standard treatments for MZLs are generally appropriate for IgG4-producing MZL.

Abstract
Background The role of antithrombotic chemoprophylaxis in prevention of venous thromboembolism (VTE) in laparoscopic surgery for gastric and colorectal malignancies is unknown. This study compared the addition of enoxaparin following intermittent pneumatic compression (IPC) with IPC alone in patients undergoing laparoscopic surgery for gastrointestinal malignancy. Methods In this multicentre RCT, eligible patients were older than 40 years and had a WHO performance status of 0 or 1. Exclusion criteria were prescription of antiplatelet or anticoagulant drugs and history of VTE. Patients were allocated to IPC or to ICP with enoxaparin in a 1 : 1 ratio. Stratification factors included sex, location of cancer, age 61 years and over, and institution. Enoxaparin was administered on days 1–7 after surgery. Primary outcome was VTE, evaluated by multidetector CT on day 7. Results Of 448 patients randomized, 208 in the IPC group and 182 in the IPC with enoxaparin group were evaluated. VTE occurred in ten patients (4·8 per cent) in the IPC group and six (3·3 per cent) in the IPC with enoxaparin group (P = 0·453). Proximal deep vein thrombosis and/or pulmonary embolism occurred in seven patients (3·4 per cent) in the IPC group and one patient (0·5 per cent) in the IPC with enoxaparin group (P = 0·050). All VTE events were asymptomatic and non‐fatal. Bleeding occurred in 11 of 202 patients in the IPC with enoxaparin group, and one patient needed a transfusion. All bleeding events were managed by discontinuation of the drug. Conclusion IPC with enoxaparin after laparoscopic surgery for gastric and colorectal malignancies did not reduce the rate of VTE.

Abstract
BACKGROUND Re-intervention after Ross procedure into the right ventricular outflow tract might be needed in patients in the long term. However, right ventricular outflow tract re-intervention indications are still unclear. Comprehensive assessment of total hemodynamics is needed. A 42-year-old Japanese woman was referred to our hospital for moderately severe pulmonary regurgitation and severe tricuspid regurgitation after a Ross-Konno procedure. Thirteen years after surgery, she developed atrial fibrillation and atrial flutter and complained of dyspnea. Electrophysiological studies showed re-entry circuit around the low voltage area of the lateral wall on the right atrium. Four-dimensional flow magnetic resonance imaging revealed moderate pulmonary regurgitation, severe tricuspid regurgitation, and a dilated right ventricle. Flow energy loss in right ventricle calculated from four-dimensional flow magnetic resonance imaging was five times higher than in normal controls, suggesting an overload of the right-sided heart system. Her left ventricular ejection fraction was almost preserved. Moreover, the total left interventricular pressure difference, which shows diastolic function, revealed that her sucking force in left ventricle was preserved. After the comprehensive assessments, we performed right ventricular outflow tract reconstruction, tricuspid valve annuloplasty, and right-side Maze procedure. A permanent pacemaker with a single atrial lead was implanted 14 days postoperatively. She was discharged 27 days postoperatively. Echocardiography performed 3 months later showed that the size of the dilated right ventricle had significantly reduced. DISCUSSION A four-dimensional imaging tool can be useful in the decision of re-operation in patients with complex adult congenital heart disease. The optimal timing of surgery should be considered comprehensively.

Abstract
OBJECTIVES Immune checkpoint inhibitors (ICIs) are less effective in non-small-cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) mutations. However, a small percentage of patients with EGFR-mutant NSCLC do respond, and the characteristics of these patients are not known. Here, we identify the characteristics of patients who may respond to ICI therapy for EGFR-mutant NSCLC. PATIENTS AND METHODS The medical records of NSCLC patients with EGFR mutations who received PD-1/PD-L1 antibody monotherapy at nine institutions were reviewed. RESULTS In total, 58 patients with EGFR-mutant NSCLC were analyzed. Various clinical factors such as smoking history and EGFR mutation type were not associated with progression-free survival (PFS) of ICIs, while the PFS of prior EGFR tyrosine kinase inhibitors (TKIs) was inversely associated with that of ICIs. Patients who responded to prior EGFR TKIs for > 10 months exhibited a significantly shorter response to ICIs compared to those who had responded for ≤ 10 months (PFS of ICI: 1.6 vs. 1.9 months; hazard ratio: 2.54; 95% confidence interval 1.26-5.12; p = 0.009). However, patients who responded to ICIs for > 6 months responded to prior EGFR TKIs for significantly shorter periods compared to those who responded to ICIs for ≤ 6 months (PFS of prior EGFR TKI: 5.3 vs. 12.1 months; log-rank test: p = 0.0025). CONCLUSION The duration of response to prior EGFR TKIs could be a predictive marker of ICI therapy in EGFR-mutant NSCLC patients.

Abstract
Previously, the main treatment for multiple myeloma (MM) was cytotoxic chemotherapies, including autologous stem-cell transplantation (ASCT), but survival benefit in the elderly was limited. More recently, clinical trials and practical experience with novel agents with superior efficacy have shown improved survival, including in the elderly. However, this improvement cannot be simply interpreted as a decline in mortality rate that is an important public health measure of progress against cancer. Here, we assessed the trends in mortality rates of MM in parallel with incidence rates in Japan and the U.S. We used national mortality data and population-based cancer registry data in both countries from 1995 to 2015, during which 74 972 patients in Japan and 229 290 patients in the U.S. died of MM. Trends in mortality and incidence rates were characterized using joinpoint regression analysis. Despite upward trends in incidence, mortality rates showed a significant decrement after 2005 in Japan, with an annual percent change [APC (95% confidence interval)] of -2.5% (-2.9% to -2.1%), and after 2002 in the U.S., with an APC of -2.0% (-2.6% to -1.5%). In both countries, the change in mortality trend coincided with the introduction of the novel agents. Moreover, improvements in mortality were particularly large in patients aged 70 to 79 years, who cannot receive ASCT. Our results indicate that the benefits of novel agents for MM are appreciable at the population level and may encourage further development of novel agents for malignancies that can be widely applied to the patients.
