Abstract
PURPOSE/OBJECTIVE(S) RTOG 0617 showed that cardiac events are relatively common after high-dose thoracic radiotherapy. The aim of this study was to investigate the incidence and risk of major cardiovascular events (MACE) after concurrent chemoradiotherapy (CCRT) with or without durvalumab in patients with stage III non-small cell lung cancer (NSCLC) using the data from a multi-institutional study in Japan. MATERIALS/METHODS Patients who received CCRT for stage III NSCLC between July 2018 and July 2019 were enrolled in a multi-institutional study in Japan. MACE was defined as follows: symptomatic pericardial effusion, acute coronary syndrome, pericarditis, significant arrhythmia, and heart failure. The cumulative incidence of MACE, accounting for death as a competing risk, was calculated. Pre-existing coronary heart disease (CHD) included coronary artery disease, congestive heart failure, peripheral vascular disease, stroke, and extensive coronary artery calcification. The association between patient/treatment-related factors and MACE was assessed by multivariate analysis. RESULTS Among 178 patients with a median follow-up period of 42.5 months, 13 patients developed MACEs. The 3-year cumulative incidence of MACE was 6.9% (95% confidence interval [CI], 4.0-11.9%). Univariate analysis showed that female sex and mean heart dose (MHD) were marginally associated (3-year cumulative incidence, male 5.6% vs. female 12.1%; P = 0.12; MHD ≥ 6.3 Gy 4.8% vs. < 6.3 Gy 9.1%; P = 0.13), and pre-existing CHD was significantly associated with an increased risk of MACE (no CHD 4.3% vs. CHD 16.8%; P = 0.026). Consolidation durvalumab was not associated with an increased risk of MACE (no durvalumab 5.2% vs. durvalumab 7.4%; P = 0.89). Multivariate analysis showed that pre-existing CHD was significantly associated with MACE (hazard ratio, 4.22; 95% CI, 1.30-13.7; P = 0.016). CONCLUSION The incidence of MACE based on the real-world data in Japan was lower than previously reported. Pre-existing CHD was associated with an increased risk of MACE after CCRT in patients with stage III NSCLC, whereas the administration of consolidation durvalumab was not associated with an increased risk of MACE.

Abstract
PURPOSE/OBJECTIVE(S) To investigate the real-world data on overall survival (OS) in patients with stage III non-small cell lung cancer (NSCLC) treated with concurrent chemoradiotherapy (CCRT) with or without consolidation durvalumab, and to perform an exploratory analysis on effective radiation dose to the immune cells (EDIC). MATERIALS/METHODS In our multi-institutional retrospective study, patients who received CCRT between July 2018 and July 2019 for stage III NSCLC in Japan were investigated. EDIC was estimated using mean lung dose, mean heart dose, body volume, body mean dose, and body weight, as reported in the secondary analysis of RTOG 0617. The cut-off value of EDIC was calculated using the maximally selected log-rank statistics. RESULTS One hundred and seventy-eight patients were eligible for the analysis (136 patients, CCRT with consolidation durvalumab [CCRT+D] cohort; 42 patients, CCRT cohort). The median follow-up period was 42.5 months. Three-year OS rates were 59.8% in the overall cohort: 60.5% in the CCRT+D cohort, and 58.0% in the CCRT cohort with no significant difference (hazard ratio [HR], 0.76; 95% confidence interval [CI], 0.45-1.27; P = 0.29). Univariate analysis showed that ECOG-PS, smoking history, histology, EGFR mutational status, gross tumor volume and EDIC were significantly associated with OS. Multivariate analysis showed that ECOG-PS 2, gross tumor volume ≥ 57 cm3 and EDIC ≥ 4.4 Gy were associated with poor OS. Among 21 EGFR-mutated patients, 3 year-OS rates were 64.7% in the CCRT+D cohort and 100% in the CCRT cohort, while 3 year-OS rates were 68.8% and 58.7% among 90 EGFR wild-type patients. Three-year OS rates were 64.6% and 47.6% for EDIC < 4.4 Gy and EDIC ≥ 4.4 Gy in the overall cohort (HR, 1.82; 95% CI, 1.14-2.90; P = 0.015). In the subgroup analysis, 66.3% vs. 44.4% in the CCRT+D cohort (HR, 2.01; 95% CI, 1.17-3.47; P = 0.016), and 59.0% vs. 56.1% in the CCRT cohort (HR, 1.20; 95% CI, 0.48-3.01; P = 0.70), respectively. CONCLUSION Our real-world data in Japan showed that there was no significant difference in OS between the CCRT+D cohort and the CCRT cohort. High EDIC could be a risk for poor OS in patients treated with CCRT and consolidation durvalumab compared with those treated with CCRT.

Abstract
A serologic investigation of Brucella infection was performed in 7 species of cetaceans inhabiting along the coast of Japan. A total of 32 serum samples were examined by
enzyme-linked immunosorbent assay (ELISA) using Brucella abortus and B. canis antigens. One serum sample from five melon-headed whales
(Peponocephala electra) was positive for B. abortus. No serum sample showed positive for B. canis. The ELISA-positive melon-headed whale
serum demonstrated a strong band appearance only against B. abortus antigens in Western blot analysis. Many detected bands were discrete, while some of them had a smeared
appearance. The present results indicate that Brucella infection occurred in melon-headed whale population and the bacterial antigenicity is more similar to that of
B. abortus than B. canis.

Abstract
Organochlorine compounds (OCs) such as polychlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane and its metabolites (DDTs), chlordane related compounds, hexachlorocyclohexane isomers (HCHs), hexachlorobenzene (HCB), tris(4-chlorophenyl) methane (TCPMe) and tris(4-chlorophenyl) methanol were determined in the blubber of Dall's porpoises (Phocoenoides dalli) collected from Japanese coastal waters in 1998/1999. Among OCs analyzed, PCBs were the predominant contaminants with concentrations ranging from 1.5 to 39 microg/g on a wet weight basis. OCs concentrations were relatively low and less variable in mature females possibly due to the lactational excretion from their bodies, while in males the concentrations were increased with body length. Concentrations and compositions of DDTs and HCHs showed significant differences between the truei-type population off the Pacific coast of northern Japan and dalli-type from the Sea of Japan/Okhotsk, suggesting its usefulness to discriminate different populations. OCs levels detected in truei-type porpoises collected in 1998/1999 were lower than those collected in 1984, except TCPMe. On the other hand, except DDTs, the residue levels of other organochlorines in dalli-type porpoises showed no significant decrease since 1984.

Abstract
Erythropoietin (Epo) is known to be a lineage specific cytokine which regulates the number of circulating erythrocytes. Most of it is produced in the kidney. Recently, Epo has been reported to be synthesized in the normal brain, placenta, and capillary endothelium. We also have found that uterine endometrium expresses Epo signals in an estrogen-dependent manner, and that Epo contributes to angiogenesis in the endometrium in mice. To clarify the functional activity of Epo in human reproductive organs, we examined Epo signaling in these organs by Southern analysis of RT-PCR products and studied the distribution of substances relevant to Epo signal transduction by immunohistochemistry and Western blotting. Epo mRNA is expressed in the normal human cervix, endometrium and ovary, but it is not always detected in the specimens. Immunohistochemical analysis revealed Epo-receptor (EpoR) protein in: a) the endothelium of vessels, in glandular and surface epithelial cells, in decidual cells of the endometrium, and b) in follicles at various stages including oocytes, granulosa, theca interna cells and lutein cells of the ovary. Moreover, co-expression of JAK2 and phosphotyrosine, which reflects tyrosine phosphorylation via JAK2, and co-expression of EpoR and STAT5, which is a transcriptional factor relevant to mitogenic activity, were seen at these Epo-responsive sites. Western blotting analysis of these organs confirmed the immunohistochemical results. These findings imply that female reproductive organs can produce Epo, and that signal transduction of Epo contributes to the cyclic changes in the female reproductive organs.

Abstract
PURPOSE The long-term safety and effectiveness of fractionated strontium-90 radiation therapy (RT) for pterygium were reviewed retrospectively. METHODS AND MATERIALS Between 1984 and 1996, 399 patients with 490 pterygia were treated with a strontium-90 eye applicator following surgical removal of the pterygium. The median follow-up period was 61 months (range 2-178). Of the 490 pterygia, 452 were fresh, 17 were recurrences after surgical removal alone, and 21 were recurrences after surgical removal plus postoperative RT. Fractionated RT of 31-42 Gy/4-5 fractions/22-29 days was given for 95.1% of the pterygia. RESULTS In total, 58 (11.8%) local recurrences of pterygia were noted. The median time of local recurrences was 10 months, ranging from 2 to 93 months, and 16 recurrences (28%) were noted later than 24 months after treatment. The interval between surgery and the start of RT (1-3 days vs. >3 days) and recurrent pterygia were significant variables for local control in the multivariate analysis, while total RT dose (7-29 Gy vs. 31-50 Gy) was a marginally significant variable. Late toxicities that may be associated with strontium-90 RT were scleromalacia (scleral thinning) in 4 eyes, adhesion of eyelids in 3 eyes, and scleral ulcer in 2 eyes. CONCLUSION Fractionated strontium-90 RT of approximately 40 Gy/4-5 fractions was safe and effective for preventing recurrence of pterygia, when RT was started within 3 days of surgery.

Abstract
Real-time ultrasonography was used to detect a small foreign body (a broken tip of a barbed broach) which had migrated into the upper lip of a 26-year-old female from the bone defect of the upper canine apex during root canal treatment 10 months previously. Intra-operative use of ultrasound was of great-help in clarifying the positional relationship between the foreign body and the surgical instruments used, and lead to a satisfactory result.

Abstract
We previously reported that v-fos transfer to a src-transformed rat 3Y1 cell line enhanced lung metastasis. To clarify the mechanism of this enhancement, we compared various biological factors related to metastatic potential between a fos-transferred highly metastatic cell line (fos-SR-3Y1-202) and the control cell line transferred with genetic marker (pSV2-neo) plus pBR322, neo-SR-3Y1-200. Lung arrest, the effect of lung extract on cell growth, or sensitivity to natural killer cells could not explain the higher metastasis of fos-SR-3Y1-202, compared to findings with neo-SR-3Y1-200. The invasiveness, assessed by penetration through a Matrigel-coated filter was about 5 times higher in fos-SR-3Y1-202 than in neo-SR-3Y1-200; high invasiveness in vitro was also observed in a fos-transferred mixed-population cell line (fos-SR-3Y1-200) and fos-transferred highly metastatic clones. Histopathological evidence of an in vivo tumor also showed the high invasiveness of fos-SR-3Y1-202 cells. To elucidate the causes of the increased invasiveness of fos-SR-3Y1-202, attachment of the cells to Matrigel and its components, such as laminin and type IV collagen, type IV collagenase activity, and motility were examined. Attachment of the cells to the substrate coated on Petri dishes or the activity of type IV collagenase did not differ significantly. On the other hand, cell motility, determined by a new method to directly quantitate alteration of cell shape continuously, using video image analysis and computer techniques, was higher in fos-SR-3Y1-202 than in neo-SR-3Y1-200. Thus, the fos-transferred cell line, fos-SR-3Y1-202 has a high invasiveness, in association with augmentation of motility, hence the enhancement of metastatic potential.

Abstract
Transfer of the v-fos oncogene into a rat 3Y1 cell line transformed by v-H-ras, which is tumorigenic but non-metastatic, enhanced lung metastasis, depending on the amount of fos-related transcripts. Enhancement of the metastatic potential was associated with increases in tumor growth rate i.m. of inoculated cells but not the rate of in vitro cell growth, irrespective of the addition of tissue (e.g. lung) extract to the regular medium. These results suggest that the v-fos oncogene increased the malignancy by altering biological factors of the recipient cells responsible for cell growth and/or survival rate in vivo.

Abstract
Transfer of the v-fos oncogene into a rat cell line transformed by Rous sarcoma virus increased both the spontaneous and experimental lung-metastasis. Metastatic ability of each v-fos transferred cell line was dependent on both the manner of integration and transcriptional amount of the v-fos oncogene, but did not correlate with the growth rate in vivo. Expression of the src, myc or ras genes were not altered by transfer of the v-fos gene, except that the myc expression was enhanced in the cell line, which acquired augmentation of growth rate in vivo but not metastatic potential to the lung. Cells of the metastatic lung nodules of each cell line also possessed exogenous fos DNA and the transcripts. These results suggest that v-fos oncogene functions in the transfected cells and causes malignant progression.
