Abstract
BACKGROUND Accumulating evidence suggests that radiotherapy success has an immune-associated component. The immunogenomic profiles associated with responses to chemoradiotherapy (CRT) were assessed in patients with locally advanced rectal cancer in this study. METHODS CD8+ tumour-infiltrating lymphocyte (TIL) and stromal lymphocyte densities were assessed by immunohistochemistry using pretreatment biopsies from patients with advanced rectal cancer who had preoperative CRT. Whole-exome sequencing and gene expression microarray analysis were conducted to investigate the genomic properties associated with the response to CRT and CD8+ TIL density. Response to CRT was determined based on Dworak tumour regression grade (TRG); tumours with complete (TRG 4) or near-complete (TRG 3) regression were grouped as good responders, and those with TRG 1 as non-responders. RESULTS Immunohistochemical examinations (275 patients) showed that pre-CRT CD8+ TIL density was associated with better response to CRT and improved recurrence-free survival, whereas pre-CRT stromal CD8+ cell density was not associated with either response to CRT or recurrence-free survival. Whole-exome sequencing (74 patients) showed that the numbers of single-nucleotide variations (SNVs) and neoantigens predicted from SNVs were higher in good responders than in non-responders, and these correlated positively with CD8+ TIL density (rS = 0·315 and rS = 0·334 respectively). Gene expression microarray (90 patients) showed that CD8A expression correlated positively with the expression of programmed cell death 1 (PDCD1) (rS = 0·264) and lymphocyte-activation gene 3 (LAG3) (rS = 0·507). CONCLUSION Pre-CRT neoantigen-specific CD8+ T cell priming may be a key event in CRT responses where immune checkpoint molecules could be useful targets to enhance tumour regression.

Abstract
Background Recurrence of pneumothorax after thoracoscopic surgery is a concerning issue for thoracic surgeons. In this study, we aimed to determine the risk factors for recurrence of spontaneous pneumothorax after thoracoscopic surgery. Methods A total of 192 patients with spontaneous pneumothorax aged <50 years who underwent thoracoscopic surgery from January 2010 to December 2016 were included in this study. Pre- and post-operative characteristics were obtained from medical records, and recurrent and non-recurrent cases were compared. Results Fourteen patients (7.3%) experienced pneumothorax recurrence. Pneumothorax recurrence was observed more frequently in patients aged <20 years (P=0.041) and those in whom bullae were not identified on preoperative computed tomography (CT) (P=0.049). The use of polyglycolic acid (PGA) sheets during surgery significantly decreased the recurrence rate (P=0.031). A history of ipsilateral pneumothorax before surgery was a significant risk factor for recurrence after thoracoscopic surgery (P=0.001). In the multivariate analysis, a history of ipsilateral pneumothorax and identification of bullae on CT were identified as significant risk factors for recurrence. Conclusions A history of ipsilateral pneumothorax, and inability to identify bullae on preoperative CT were risk factors for postoperative recurrence of pneumothorax.

Abstract
OBJECTIVES Difficult thoracoscopic surgery sometimes requires a long operative time. It is unclear whether patients benefit from such thoracoscopic surgeries. We investigated whether thoracoscopic surgery for difficult cases contributed to improvements in perioperative outcomes. METHODS We retrospectively reviewed cases of anatomical lung resection with thoracoscopic surgery, including conversion to thoracotomy, between January 2006 and December 2016 and compared patient demographics and perioperative outcomes of the long (≥360 min) and the normal operative time groups (<360 min). RESULTS One hundred and seventy-six patients were in the long operative time group and 655 patients were in the normal operative time group. The long operative time group had more male patients, more progressive clinical stages, bilobectomy or pneumonectomy, conversion to thoracotomy and more blood loss than the normal operative time group. The long operative time group had higher rates of postoperative complications and longer hospital stay (30% vs 16%, P < 0.001 and 9 ± 9 days vs 7 ± 8 days, P < 0.001; respectively). Multivariate analysis showed that in the first half of the operative period, chronic obstructive pulmonary disease and bilobectomy or pneumonectomy were independent predictive factors for postoperative complications. The long operative time as a factor was close to statistical significance (odds ratio 1.689, P = 0.079) unlike the elective conversion to thoracotomy (odds ratio 0.784, P = 0.667) and emergency conversion to thoracotomy (odds ratio 0.938, P = 0.924). CONCLUSIONS In conclusion, when difficult cases are encountered, conversion to thoracotomy should be considered by surgeons if continuation of thoracoscopic surgery increases the operative time.

Abstract
Desmoid-type fibromatosis is a rare soft tissue tumor and the chest wall is one of the common sites of its extra-abdominal occurrence. A bifid rib is one of the congenital rib abnormalities. We report a case of desmoid-type fibromatosis arising in a chest wall's bifid rib. A 42-year-old female complained of right chest pain without remarkable medical, traumatic, or familial history. Chest-computed tomography revealed a chest wall tumor located adjacent to a bifid costal cartilage of third rib. We performed chest wall resection of second and third ribs. Pathologically, the tumor was diagnosed a desmoid-type fibromatosis of the chest wall. We surmise mechanical stimulation due to the bifid rib may be related to the occurrence of the tumor. In case of desmoid-type fibromatosis without somatic gene mutation, traumatic history, wound, implants, or use of female hormonal agents, we should search also local congenital abnormality.

Abstract
Patient-reported outcome measures (PROMs) are utilized in health care to quantify the patient's perspective of a health condition or treatment on outcomes, such as health-related quality of life (HRQoL) and patient satisfaction. In dermatology, this is particularly relevant because the patient's perspective is critical in evaluating the outcome of cosmetic procedures as well as skin cancer treatment. We review seven validated PROMs that have been reported in the dermatologic surgery and cosmetic dermatology literature. For patients undergoing cosmetic procedures, the use of PROMs provides additional valuable outcome data beyond physician assessment. For patients with skin cancer, women experience a unique and often greater impact on HRQoL during treatment, which has been captured through PROMs. The recent development of multi-module instruments, such as the FACE-Q and FACE-Q Skin Cancer, have facilitated comprehensive assessments of treatment that impact multiple domains of HRQoL. The use of PROMs allows for dermatologists to reliably capture important disease- and treatment-related concerns, thus improving the patient experience.

Abstract
PURPOSE To evaluate clinical features of Japanese patients with anti-α-enolase antibody-positive autoimmune retinopathy (anti-enolase AIR). DESIGN Multicenter retrospective observational case series. METHODS Forty-nine eyes of 25 Japanese anti-enolase AIR patients (16 female and 9 male; mean age at first visit, 60.8 years) were included. Fundus characteristics, perimetry, spectral-domain optical coherence tomography (SD-OCT), electroretinography (ERG), best-corrected visual acuity (BCVA), and complicating systemic tumors were assessed. Protein localization of α-enolase was examined by immunohistochemistry in an enucleated eye of 1 patient. RESULTS Patients were classified into 3 groups: multiple drusen (48%), retinal degeneration (36%), and normal fundus (16%). Drusen varied in size from small deposits to vitelliform-like lesions. Images on SD-OCT revealed dome-shaped hyperreflectivity beneath the retinal pigment epithelium (RPE), corresponding to drusen. Perimetry showed that ring scotoma was the most frequent (39%). Rod-system and/or single-flash cone responses revealed decreased responses in 81% of the eyes. Combined rod and cone system responses demonstrated significantly lower a-wave amplitudes in the degeneration group than in the drusen group (P = .005). BCVA was improved or maintained in 80% of the eyes during follow-up. Malignant or benign tumors were detected in 30% of patients. The RPE and photoreceptor layers were immunopositive for α-enolase. CONCLUSIONS The drusen subtype, scarcely described in the literature, is suggested to characterize Japanese patients with anti-enolase AIR. The different funduscopic features with different functional severities may have resulted from antibody-mediated damage to RPE as well as photoreceptor cells.

Abstract
Background The present study evaluated the impact of the introduction of thoracoscopic lung lobectomy (TL) for non-small cell lung cancer at our institution. Methods This study retrospectively compared surgical and oncological outcomes in the period before and after the introduction of TL for non-small cell lung cancer. Propensity score-matched analysis was performed with respect to baseline patient variables and tumor characteristics. Results Patients were divided into two groups: those who underwent lung lobectomy in the period before (BI group, n=261) and after (AI group, n=261) the introduction of TL. The proportion of TLs at our institution increased from 1.3% in the BI group to 93% in the AI group. The AI group experienced a longer duration of surgery, lesser intraoperative blood loss, and a significantly shorter postoperative hospital stay (POHS). There were no significant differences in postoperative complications between the two groups. The median follow-up period was 50 months in both groups. No significant differences were observed between the BI and AI groups with respect to 5-year overall survival (OS) (76.1% and 71.7%, respectively; P=0.1973) and disease-free survival (DFS) (67.6% and 66.1%, respectively; P=0.4071). On multivariate analysis, pathological N1-2 status was an independent predictor of survival. AI group and TL showed no independent association with survival. Conclusions The introduction of TL represented a positive change at our institution owing to decreased invasiveness and oncological equivalence of the surgical treatment for non-small cell lung cancer.

Abstract
Purpose: Higher serum 25-hydroxyvitamin D (25(OH)D) levels are reportedly associated with better survival in early-stage non-small cell lung cancer (NSCLC). Therefore, whether vitamin D supplementation can improve the prognosis of patients with NSCLC was examined (UMIN000001869).Patients and Methods: A randomized, double-blind trial comparing vitamin D supplements (1,200 IU/day) with placebo for 1 year after operation was conducted. The primary and secondary outcomes were relapse-free survival (RFS) and overall survival (OS), respectively. Prespecified subgroup analyses were performed with stratification by stage (early vs. advanced), pathology (adenocarcinoma vs. others), and 25(OH)D levels (low, <20 ng/mL vs. high, ≥20 ng/mL). Polymorphisms of vitamin D receptor (VDR) and vitamin D-binding protein (DBP) and survival were also examined.Results: Patients with NSCLC (n = 155) were randomly assigned to receive vitamin D (n = 77) or placebo (n = 78) and followed for a median of 3.3 years. Relapse and death occurred in 40 (28%) and 24 (17%) patients, respectively. In the total study population, no significant difference in either RFS or OS was seen with vitamin D compared with the placebo group. However, by restricting the analysis to the subgroup with early-stage adenocarcinoma with low 25(OH)D, the vitamin D group showed significantly better 5-year RFS (86% vs. 50%, P = 0.04) and OS (91% vs. 48%, P = 0.02) than the placebo group. Among the examined polymorphisms, DBP1 (rs7041) TT and CDX2 (rs11568820) AA/AG genotypes were markers of better prognosis, even with multivariate adjustment.Conclusions: In patients with NSCLC, vitamin D supplementation may improve survival of patients with early-stage lung adenocarcinoma with lower 25(OH)D levels.

Abstract
Phosphorothioate modification of oligonucleotides is one of the most promising chemical modifications in nucleic acid therapeutics. Structurally similar 5'-thio or phosphorothiolate-modified nucleotides, in which the 5'-bridging oxygen atom is replaced with a sulfur atom, are attracting attention and gaining importance in oligonucleotide-based research. In our present study, we synthesized 5'-thio-2',4'-BNA/LNA monomers bearing thymine or 5-methylcytosine nucleobase. The 5'-thio-2',4'-BNA/LNA monomers were successfully incorporated into target oligonucleotides, and their nuclease stability and binding affinity with complementary strands were evaluated.

Abstract
The reported prevalence of sarcopenia has shown a wide range, crucially based on the diagnostic criteria and setting. This cross-sectional study evaluated the prevalence of sarcopenia and sought to identify factors associated with sarcopenia on admission in a specialized geriatric rehabilitation setting based on the newly developed the Asian Working Group for Sarcopenia algorithm. Among 87 participants (mean age, 76.05 ± 7.57 years), 35 (40.2%) were classified as showing sarcopenia on admission. Prevalence was high, particularly among participants ≥80 years old, with tendencies toward lower body mass index, smoking habit, lower cognitive function, and greater functional impairment compared with the non-sarcopenic group. Identification of sarcopenia in elderly patients before rehabilitation and consideration of risk factors may prove helpful in achieving rehabilitation outcomes.
