Abstract
Durvalumab has been administered to patients with unresectable stage III non-small cell lung cancer (NSCLC). However, it remains unclear whether durvalumab benefits these patients with epidermal growth factor receptor (EGFR) mutation. We conducted a retrospective, multicenter study of patients with EGFR mutation who received chemoradiotherapy (CRT) between June 2018 and March 2021. We assessed patient characteristics, efficacy of durvalumab, and durvalumab safety before and after targeted therapy. We collected data on a total of 673 patients, of whom 401 (59.6%) underwent EGFR mutation testing. Fifty-one patients were EGFR positive and 311 were EGFR negative. In the EGFR-positive group, there were higher proportions of females, never-smokers, and patients with adenocarcinoma histology. Of the 51 patients in the positive group and 311 in the negative group who received CRT, 45 (88.2%) and 247 (79.4%) received durvalumab, with median progression-free survival of 23.0 and 24.2 months in the positive and negative groups, respectively (hazard ratio 1.03; 95% confidence interval: 0.64-1.67). The main adverse event was pneumonitis (positive group: 62.2%; 4.4% grade 3; negative group: 62.3%; 6.9% grade 3). No treatment-related deaths were observed. Of the 45 patients in the positive group who received durvalumab, 14 (31.1%) received targeted therapy after durvalumab at the data cutoff. One patient discontinued targeted therapy after developing pneumonitis. In patients with unresectable stage III NSCLC with EGFR mutation, durvalumab after CRT is potentially safe and effective. This may be a suitable treatment sequence for these patients.

Abstract
A 75-year-old male with diabetes mellitus was referred to our hospital with an abnormal shadow on chest radiography, based on which he was diagnosed with extensive-disease small-cell lung cancer (ED-SCLC; cT2bN2M1a). The first-line therapy comprised atezolizumab, carboplatin, and etoposide. After four cycles, the patient achieved complete response (CR), and maintenance therapy was initiated with atezolizumab. However, even though CR was maintained, maintenance therapy was discontinued after 16 cycles due to persistent grade 2 anorexia and fatigue. Simultaneously, the HbA1c decreased to 5.5%, and antidiabetic therapy was discontinued. Six months after the last dose of atezolizumab, the patient visited the emergency room because of anorexia, dry mouth, and fatigue. Laboratory findings were as follows: blood glucose was 668 mg/dL, glycated hemoglobin (HbA1c) was 8.8%, urine ketone was 2+, sodium (Na) was 127 mmol/L, potassium (K) was 6.5 mmol/L, creatinine (Cre) was 1.43 mg/dL, and arterial pH was 7.29. Based on these findings, his presentation was consistent with fulminant type 1 diabetes mellitus (T1DM) complicated by diabetic ketoacidosis (DKA). Regular continuous insulin and saline administration was initiated in the intensive care unit, and acidosis and electrolyte abnormalities were corrected. His C-peptide was <0.03 ng/mL. His insulin secretory capacity was considered to be depleted, and he required continuous subcutaneous insulin injections. Glutamic acid decarboxylase and insulin autoantibodies were absent. The complete response persisted without further therapy until two years since the event.

Abstract
BACKGROUND Mycobacterium lentiflavum is a slow-growing nontuberculous mycobacterium that is widely distributed in soil and water systems, but it is sometimes pathogenic to humans. Although cases of M. lentiflavum infections are rare, 22 isolates of M. lentiflavum were identified at a single hospital in Japan. We suspected a nosocomial outbreak; thus, we conducted transmission pattern and genotype analyses. METHODS Cases of M. lentiflavum isolated at Kushiro City General Hospital in Japan between May 2020 and April 2021 were analyzed. The patient samples and environmental culture specimens underwent whole-genome sequencing (WGS). Additionally, we retrospectively collected clinical data from patient medical records. RESULTS Altogether, 22 isolates of M. lentiflavum were identified from sputum and bronchoalveolar lavage samples. Clinically, the instances with M. lentiflavum isolates were considered contaminants. In the WGS analysis, 19 specimens, including 18 patient samples and 1 environmental culture from the hospital's faucet, showed genetic similarity. The frequency of M. lentiflavum isolation decreased after we prohibited the use of taps where M. lentiflavum was isolated. CONCLUSIONS WGS analysis identified that the cause of M. lentiflavum pseudo-outbreak was the water used for patient examinations, including bronchoscopy.

Abstract
BACKGROUND Shifting enables flexible switch between tasks or mental sets. It is a component of the executive function that plays critical roles in human behaviour control. However, shifting ability in individuals with intellectual disability (ID) has not been well clarified because of the use of intellectually demanding tasks in previous studies. The present study invented a novel shifting task with minimal intellectual demands and aimed to clarify the characteristics of shifting in adolescents with ID. METHODS Adolescents with ID (n = 21) and chronological-age-matched (n = 10) and mental-age-matched controls (n = 33) performed a novel shifting task with simple rule switching (i.e. change in direction). Analyses focused on the switch cost or the increase in the reaction time associated with rule switching. RESULTS Two subtypes of adolescents with ID were found with respect to the switch cost: one that lacks it and another with an increased switch cost. The lack of a switch cost was unique to the subgroup adolescents with ID and was not indicated in the control group. CONCLUSIONS The present study indicated that shifting in adolescents with ID does not depend solely on their intellectual function and is highly heterogeneous. This finding further implies that executive functions, including shifting, must be evaluated separately from their intellectual functions.

Abstract
AIM To determine whether the pathological response to preoperative chemotherapy for pancreatic ductal adenocarcinoma (PDAC) can be predicted using 2-[18F]-fluoro-2-deoxy-d-glucose positron-emission tomography (F-18 FDG-PET). MATERIALS AND METHODS Twenty-eight patients with PDAC who underwent only neoadjuvant chemotherapy (NAC) before surgery were enrolled in the study. All patients had F-18 FDG-PET examinations before NAC. The resected specimen was pathologically evaluated according to the Classification of Pancreatic Carcinoma (7th edn). Patients were categorised into a non-response group and a response group based on the pathological findings. The non-response group (Grades 1a and 1b) showed ≤50% necrosis in the specimen, while the specimens of the response group (Grades 2-3) showed >50% necrosis. The maximum standardised uptake values (SUVmax) of the tumours on F-18 FDG-PET were measured. The mean values of SUVmax were compared between the two groups. The diagnostic performance of SUVmax in distinguishing the two groups was also evaluated using receiver operating characteristic analysis. RESULTS The mean SUVmax of the response group was higher than that of the non-response group (9.00 ± 1.78 versus 4.26 ± 2.35; p<0.001). The optimal cut-off value of SUVmax was 9.28 for distinguishing the two groups. The sensitivity, specificity, and accuracy for the prediction in the response group were 80%, 95.7%, and 92.9%, respectively. CONCLUSIONS SUVmax on F-18 FDG-PET may be useful as a biomarker to predict the pathological response to NAC in patients with PDAC.

Abstract
It is not clear whether pembrolizumab monotherapy (MONO) or pembrolizumab plus platinum‐based chemotherapy (COMB) should be selected for patients with advanced non–small‐cell lung cancer (NSCLC) exhibiting high PD‐L1 expression (tumor proportion score ≥ 50%). We performed a retrospective, multicenter study of 300 patients with NSCLC exhibiting high PD‐L1 expression who received MONO or COMB as first‐line treatment between December 2018 and January 2020. We reviewed the medical records of all consecutive patients with no driver mutations, and assessed the patient characteristics, therapeutic regimens, treatment periods, and adverse events. In total, 166 (55%; median age: 74 years) and 134 (45%; median age: 68 years) patients received MONO and COMB, respectively. Patients were younger and had better performance status (0–1) in the COMB group (p < 0.01). With a median follow‐up time of 10.6 (range: 0.1–20.6) months, the median progression‐free survival was 7.1 months with MONO and 13.1 months with COMB. The objective response rate was 42.2% with MONO and 67.9% with COMB. With respect to treatment discontinuation, 36 out of 166 (21.7%) and 28 out of 134 (20.1%) patients discontinued MONO and COMB, respectively. In conclusion, COMB may be a promising option for first‐line treatment for NSCLC with high PD‐L1 expression and good performance status.

Abstract
Background There is a body of evidence to suggest that cigarette smoking increases the risk of cervical cancer in women, but no study has examined the magnitude of the association in Japanese women. Here, we evaluated the association between cigarette smoking and the risk of cervical cancer in Japanese women based on a systematic review of epidemiological evidence. Methods Original data were obtained from a MEDLINE search using PubMed or from a search of the 'Ichushi' database, as well as by a manual search. Evaluation of associations was based on the strength of evidence and the magnitude of association, together with biological plausibility as evaluated previously by the International Agency for Research on Cancer. Meta-analysis of associations was also conducted to obtain a summarized overview of the data. Results We identified two cohort studies and three case-control studies. All five studies had indicated strong positive associations between cigarette smoking and the risk of cervical cancer. Our summary estimate indicated that the relative risk (RR) for individuals who had ever-smoked relative to never-smokers was 2.03 (95% confidence interval: 1.49-2.57). Four studies had also demonstrated dose-response relationships between cigarette smoking and the risk of cervical cancer. Conclusion We conclude that there is convincing evidence that cigarette smoking increases the risk of cervical cancer among Japanese women.

Abstract
A history of hypertension is a known risk factor for delirium in patients in intensive care units, but the effect of antihypertensive agents on delirium development is unclear. Nicardipine, a calcium channel blocker, is widely used in ICU as a treatment agent for hypertensive emergency. This study investigated the relationship between the administration of nicardipine hydrochloride and delirium development in patients under mechanical ventilation. We conducted a medical chart review of 103 patients, who were divided into two groups according to the use of nicardipine hydrochloride. The prevalence of delirium was compared with respect to factors such as age, sex, laboratory data, and medical history, by multivariate analysis. 21 patients (20.4 %) were treated with nicardipine hydrochloride in 103 patients. The treatment and non-treatment groups differed significantly in age (72 vs. 65 years) and history of high blood pressure (57% vs. 11%). Multivariate analysis revealed that patients in the treatment group developed delirium significantly less often than those in the non-treatment group (19% vs. 48%). These results suggested that treatment of high blood pressure with nicardipine hydrochloride is a possible method for preventing the development of delirium.

Abstract
We present a case series of four siblings with hereditary hemorrhagic telangiectasia (HHT) and pulmonary arteriovenous malformations (PAVM). The patients' mother has HHT. Case 1: A 22-year-old man developed dyspnea and epistaxis. CT revealed a large PAVM, treated by segmentectomy. Case 2: A 27-year-old woman developed epistaxis and dyspnea. CT revealed three PAVMs, treated by partial resection. Case 3: A 20-year-old woman developed dyspnea. CT revealed multiple PAVMs, treated with endovascular occlusion of the largest one. Case 4: A 12-year-old woman developed epistaxis. CT revealed multiple PAVMs, observed without treatment. Genetic testing identified a new mutation, ENG c.1517T>C (p.Leu506Pro), in all patients and their mother. We suspect that HHT in these patients may be associated with this ENG mutation.

Abstract
A comprehensive evidence-based cancer prevention recommendation for Japanese was developed. We evaluated the magnitude of the associations of lifestyle factors and infection with cancer through a systematic review of the literature, meta-analysis of published data, and pooled analysis of cohort studies in Japan. Then, we judged the strength of evidence based on the consistency of the associations between exposure and cancer and biological plausibility. Important factors were extracted and summarized as an evidence-based, current cancer prevention recommendation: 'Cancer Prevention Recommendation for Japanese'. The recommendation addresses six important domains related to exposure and cancer, including smoking, alcohol drinking, diet, physical activity, body weight and infection. The next step should focus on the development of effective behavior modification programs and their implementation and dissemination.

Abstract
Spermatogonial stem cells (SSC) self-renew and differentiate into spermatocytes to produce haploid sperm. Because SSC are a small population of adult stem cells in the testis, numerous studies have been reported to derive cell lines from cultured SSC. It has been reported that neonatal and adult mouse SSC can be cultured in vitro over the long term. Male germline stem (GS) cells, embryonic stem (ES)-like cells, and multipotent male germline stem (MGS) cells were derivated from mouse SSC. However, in domestic species including cattle, information about in vitro culture of SSC is mainly available in the neonatal and immature animal. To our knowledge, there are no reports about long-term culture of SSC isolated from adult bovine testis. In this report, we established culture conditions to maintain SSC isolated from adult and immature testes. The SSC were isolated by 3-step enzymatic digestion and enriched by Percoll gradient centrifugation. For adult testicular cell suspensions, SSC were further enriched by differential plating on precoated gelatin dish. After Percoll gradient centrifugation, we found differential expression of SSC markers (GFRα-1 and UCHL-1) in the isolated cells from immature and adult testis. The RT-PCR results also confirmed the expression of differentiated spermatogonia markers (SYCP3 and STRA-8) in adult testicular cell suspensions. It suggests that isolated testicular germ cell population from adult testis are more heterogeneous than those of immature testis. The SSC isolated from adult testes were cultured in low-serum media containing 6-bromoindirubin-3′-oxime (BIO), an inhibitor of glycogen synthase kinase-3α (GSK3), and subsequently the cultures were maintained in the medium containing glial cell line-derived neurotropic factor (GDNF). The cell lines have characteristics resembling mouse GS cell lines as confirmed by their grape-like shape morphology, the expression of SSC markers (UCHL-1, DBA, and GFRa-1), and pluripotent stem cell markers (POU5F1, SOX2, KLF4). The SSC from immature testes were proliferated for more than 3 months in serum-free culture conditions in the presence of GDNF and bovine leukemia inhibitory factor (LIF). The cell lines had ES-like cell morphology, expressed pluripotent stem cell markers and SSC-specific markers. They differentiated in vitro into 3 germ layers confirmed by the expression of ectoderm (NESTIN), mesoderm (BMP4), and endoderm (GATA-6) markers by RT-PCR and neuron like-cells confirmed by the expression of glial fibrillary acidic protein (GFAP) by immunofluorescence analysis. In conclusion, these findings indicate an efficient method to enrich SSC without cell sorting method and different long-term culture systems subsequently established to maintain SSC from adult and immature testes. Furthermore, our data would be useful for further studies that aim to preserve endangered species and improve livestock production through genome editing technology.

Abstract
BACKGROUND Difficult mask ventilation is common and is known to be associated with sleep-disordered breathing (SDB). It is our hypothesis that the incidence of expiratory retropalatal (RP) airway closure (primary outcome) during nasal positive pressure ventilation (PPV) is more frequent in patients with SDB (apnea hypopnea index ≥5 h-1) than non-SDB subjects. METHODS The severity of SDB was assessed before surgery using a portable sleep monitor. In anaesthetized and paralysed patients with (n=11) and without SDB (n=9), we observed the behaviour of the RP airway endoscopically during nasal PPV with the mouth closed and determined the dynamic RP closing pressure, which was defined as the highest airway pressure above which the RP airway closure was reversed. The static RP closing pressure was obtained during cessation of mechanical ventilation in patients with dynamic RP closure during nasal PPV. RESULTS The expiratory RP airway closure accompanied by expiratory flow limitation occurred more frequently in SDB patients (9/11, 82%) than in non-SDB subjects (2/9, 22%; exact logistic regression analysis: P=0.022, odds ratio 3.6, 95% confidence interval 1.1-15.4). Receiver operating characteristic curve analyses indicated AHI >10h-1 and presence of habitual snoring as clinically useful predictors for the occurrence of RP closure during PPV. Dynamic RP closing pressure was greater than the static RP closing pressure by approximately 4-5 cm H2O. CONCLUSIONS Valve-like dynamic RP closure that limits expiratory flow during nasal PPV occurs more frequently in SDB patients.

Abstract
Chest wall tumors are relatively rare, and hematogenous metastasis to the chest wall is very rare. We herein describe a rare case of occult thyroid carcinoma as metastasis to the chest wall in an 80-year-old woman. The patient received detailed examinations of the chest wall tumor, and the results suggested that she had occult thyroid carcinoma. Surgery was then performed to remove all of her thyroid. As a result, she was diagnosed with follicular carcinoma of the thyroid. We report an extremely rare case of occult thyroid carcinoma diagnosed as hematogenous metastasis to the chest wall.

Abstract
OBJECTIVES To characterize patients experiencing late recurrence after primary radical surgery for renal cell carcinoma and to approach the mechanism of late recurrence. METHODS We retrospectively analyzed 657 consecutive patients who underwent radical surgery for pathologically confirmed ≤stage III renal cell carcinoma in a single institution between January 1981 and December 2008. Early or late recurrence was defined as a recurrence occurring before or after 60 months after primary surgery. RESULTS Of 657 patients, 96 (14.6%) experienced early recurrence, and 41 (6.2%) developed late recurrence. Patients with late recurrence had smaller diameter of primary tumor (median 5 cm vs 8 cm, P < 0.001), lower pathological stage (P < 0.001) and lower nuclear grade (P = 0.004) at primary surgery than those with early recurrence. On multivariate analysis, vascular invasion (including microscopic and gross invasion) was the predictor of late recurrence (P < 0.01, HR 3.79). Overall survival and disease-specific survival after recurrence were longer in patients with late recurrence (median 64 and 76 months, respectively) than in those with early recurrence (34.5 and 35 months, respectively; P = 0.008 and 0.002). CONCLUSIONS These results suggest that micrometastasis at the time of surgery associated with vascular invasion at primary tumor site and their relatively lower malignant potential could lead to late recurrence. Further studies are warranted for better understanding and managing late recurrence of renal cell carcinoma.

Abstract
One of our co-workers was sensitized with a 1% DNCB solution in acetone. Biopsies were obtained from skin lesions 1, 2, 4, 8, 12, 24, 30, 36 and 48 hours after a challenge with 0.1% DNCB solution. In the upper dermis, a rapid decrease of tissue fibrinolytic activity was found which disappeared after 30 hours. In the lower dermis, biphasic changes were observed. Tissue fibrinolytic activity increased one hour and 12-36 hours after challenge, whereas at 48 hours, when erythema was most intensive, it decreased in comparison to the normal activity. Erythema and histological changes of the epidermis and the dermis appeared after approximately 12 hours. As for lymphocytes, T-cells were seen at first. Furthermore, B-cells were noted after approximately 30 hours when marked infiltration began to appear.

Abstract
Although Sho-seiryu-to (SST), used as a traditional herbal (Kampo) medicine mainly in China and Korea, is shown to have immunomodulating potential, such as an anti-allergic one, its underlying mechanism has not been completely clarified. To partially address the issue, we explored its effects on allergen-exposed mononuclear cells. Male balb/c mice were intraperitoneally administered ovalbumin (OVA: 20 μg) plus alum or vehicle twice (Day 0 and Day 14). At Day 21, mice were sacrificed and splenocytes (mononuclear cells) were isolated and cultured in the presence or absence of OVA with or without SST. Thereafter, helper T-related cytokines in the culture supernatants were evaluated by means of ELISA. Protein level of interferon-γ was lower than 5.0 pg/mL in the supernatants from OVA non-exposed or -exposed mononuclear cells in the presence or absence of OVA stimulation. On the other hand, SST induced the cytokine from both types of mononuclear cells in the presence (P < 0.05) or absence of OVA stimulation as compared to corresponding control. By contrast, interleukin (IL)-4 level tended to be decreased by SST in OVA-non-exposed mononuclear cells as did IL-13 in both non-exposed and exposed mononuclear cells as compared to vehicle. In conclusion, immunoregulating efficacy by SST on allergy-prone subjects may include, at least in part, restoring helper T balance mainly through hyperproduction of IFN-γ against mononuclear cells such as lymphocytes.

Abstract
BACKGROUND This study aimed to determine the clinical benefit of neoadjuvant methotrexate, doxorubicin, vinblastine, and cisplatin (MVAC) in patients with muscle-invasive bladder cancer (MIBC) treated with radical cystectomy. PATIENTS AND METHODS Patients with MIBC (T2-4aN0M0) were randomised to receive two cycles of neoadjuvant MVAC followed by radical cystectomy (NAC arm) or radical cystectomy alone (RC arm). The primary end point was overall survival (OS). Secondary end points were progression-free survival, surgery-related complications, adverse events during chemotherapy, proportion with no residual tumour in the cystectomy specimens, and quality of life. To detect an improvement in 5-year OS from 45% in the RC arm to 57% in the NAC arm with 80% power, 176 events were required per arm. RESULTS Patients (N = 130) were randomly assigned to the RC arm (N = 66) and the NAC arm (N = 64). The patient registration was terminated before reaching the initially planned number of patients because of slow accrual. At the second interim analysis just after the early stoppage of patient accrual, the Data and Safety Monitoring Committee recommended early publication of the results because the trial did not have enough power to draw a confirmatory conclusion. OS of the NAC arm was better than that of the RC arm, although the difference was not statistically significant [hazard ratio 0.65, multiplicity adjusted 99.99% confidence interval 0.19-2.18, one-sided P = 0.07]. In the NAC arm and the RC arm, 34% and 9% of the patients had pT0, respectively (P < 0.01). In subgroup analyses, OS in almost all subgroups was in favour of NAC. CONCLUSIONS This trial showed a significantly increased pT0 proportion and favourable OS of patients who received neoadjuvant MVAC. NAC with MVAC can still be considered promising as a standard treatment. UMIN CLINICAL TRIALS REGISTRY IDENTIFIER C000000093.

Abstract
We used FM imaging to identify neurons that receive sensory feedback from the body wall in a circuit for octopamine (OA)-evoked rhythmic locomotion in the earthworm, Eisenia fetida. We visualized synapses in which postsynaptic neurons receive the sensory feedback, by using FM1-43 dye to label the synapses of both motor and sensory pathways that are associated with locomotion, then clearing the motor pathway synapse labeling, and finally identifying the target synapses by distinguishing physiologically functional synapses through destaining using a high-K(+) solution. A pair of synaptic regions associated with the sensory feedback was found to be located two or three cell body-widths away from the midline, between the anterior parts of the roots of the second lateral nerves (LNs) at the segmental ganglia (SGs). Using conventional intracellular recording and dye loading of the cell bodies surrounding these synaptic regions, we identified a pair of bilateral neurons with cell bodies larger than those of other cells in these regions, and named them "Oscillatory firing neurons Projecting to Peripheral nerves" (OPPs). These had a bipolar shape and projected neurites to the ipsilateral first and third LNs, fired rhythmically, and had a burst timing synchronized with the motor pattern bursts from the ipsilateral first LNs. Current injection into an OPP caused firing in the ipsilateral first LNs, supporting the hypothesis that OPPs functionally project to the peripheral nerves. OPPs also sent neurites to the adjacent anterior and posterior SGs, suggesting connections with the adjacent segments. We conclude that FM imaging can be used to identify neurons involved in specific functions, and that OPPs are the first neurons to be associated with OA-induced locomotion in the earthworm.

Abstract
OBJECTIVES To clarify the effect of the time from the presentation of symptoms to medical consultation (time to consultation) on oncological outcomes in men with testicular cancer and to examine whether the recent improvement of delays in consultation has led to better outcomes. METHODS We reviewed 175 consecutive patients registered for testicular cancer (124 men with seminoma and 51 men with nonseminoma) at a single institution between 1991 and 2010. RESULTS Men with the time to consultation of>6 months (n = 56) had a poorer overall survival than those with the time to consultation of ≤ 6 months (log-rank test, P = 0.028), despite similar disease stage between them (P = 0.897) and less prevalent nonseminoma in the former (P = 0.032). Although the negative effect of consultation delay on overall survival was significant only in nonseminoma histology (log-rank test, P = 0.004), the time to consultation of>6 months was an independent risk factor associated with poorer overall survival (hazard ratio [HR] = 18.0, 95% confidence interval [CI]: 1.78-182, P = 0.014), in addition to nonseminoma histology (HR = 17.4, 95% CI: 1.38-219, P = 0.027) and stage II or higher disease (HR = 12.9, 95% CI: 1.36-123, P = 0.026) in all the patients. The time to consultation was positively correlated with the primary tumor size (P<0.001). The time to consultation was shorter and the primary tumor size was seemingly smaller in patients registered between 2001 and 2010 (n = 104) than in those registered between 1991 and 2000 (median 74 d vs. 109 d, P = 0.042 and 5.8 ± 2.6 cm vs. 6.7 ± 3.3 cm, P = 0.068, respectively), although disease stage and overall survival were not different between the 2 periods (P = 0.233 and log-rank test, P = 0.719, respectively). CONCLUSIONS The time to consultation and primary tumor size showed a strong positive correlation in men with testicular cancer. Delays in consultation had a negative effect on their survival, particularly in those with nonseminoma. The time to consultation significantly shortened and the primary tumor size was reduced with a borderline significance in men registered between 2001 and 2010 compared with those between 1991 and 2000, although stage migration or survival improvement in recent years was not observed.

Abstract
In order to determine the molecular basis of cytoplasmic male sterility (CMS) in alloplasmic lines of eggplant, the genomic structures and transcription patterns of mitochondrial ATP synthase subunit (atp) and cytochrome oxidase subunit (cox) genes were studied for wild and cultivated eggplants. Alloplasmic eggplant lines with cytoplasms of wild Solanum species showing either anther indehiscent type of CMS or non-pollen production type of CMS were studied with the cultivated eggplant Solanum melongena, used as a control. Southern hybridization of the mitochondrial genes indicated the difference between the two types of CMS and showed complete identity within each type. The cytoplasmic patterns of all wild species differed from that of the cultivated eggplant. Thus, the cytoplasm of the six wild eggplants and the one cultivated eggplant was classified into three groups. Male sterile plants of both types of CMS showed novel transcription patterns of atp1, whereas a different transcription pattern of cox2 was observed only in the anther indehiscent type. Based on these differences, we determined the DNA sequences of about a 4 kbp segment in the atp1 region. Although the coding and 3' flanking regions were almost identical among the cytoplasms, the 5' flanking region was completely different and novel open reading frames (orfs) were found for each of the CMS types and the cultivated eggplant. The cytoplasm of Solanum kurzii inducing the anther indehiscent type CMS had orf312, and those of Solanum aethiopicum and Solanum grandifolium of non-pollen production type CMS had orf218. The correspondence between the transcription patterns of these orfs and phenotypic expression of male sterility strongly suggests that these orfs are causal genes for each type of CMS.

Abstract
4526 Background: Cisplatin-based NAC for patients (pts) with MIBC is considered to provide a 5–8% overall survival (OS) advantage, although several studies failed to prove the survival benefit of NAC. Methods: Eligibility criteria included histologically proven urothelial carcinoma, MIBC (T2-4aN0M0) within 8 weeks from TURBT, PS 0-1, and age 20-75 years old. Patients were randomized to receive 2 cycles of neoadjuvant MVAC followed by RC (NAC arm) or RC alone (RC arm). The primary endpoint was OS. Secondary endpoints were progression-free survival (PFS), surgery-related complications, adverse events during NAC, the percent with no residual tumor in the RC specimens (pT0), and QOL. The sample size was 180 pts in each arm with a one-sided alpha of 5% and a power of 80% to detect a 7% difference in 5-year OS, 45% in the RC arm, and 57% in the NAC arm. Results: From March 2003 to March 2009, 130 pts were randomized to the NAC arm (n=64) and RC arm (n=66). Fifty-nine patients in the NAC arm and 65 in the RC arm underwent cystectomy. The patient registration was terminated early because of slow accrual. At the 2nd interim analysis conducted after the completion of patient accrual, OS of the NAC arm was better than that of the RC arm, although the difference was not statistically significant (HR, 0.65; multiplicity adjusted 99.99%CI, 0.19-2.18; one-sided log-rank p = 0.07). Considering the current situation in which NAC with gemcitabine and cisplatin (GC) is widely used in clinical practice, the Data and Safety Monitoring Committee recommended early publication of the results. PFS of the NAC arm was better than that of the RC arm (HR, 0.61; 95% CI, 0.35-1.06, one-sided log-rank p=0.04). No differences in perioperative complications, other than lymph leakage, were observed between the arms. In the NAC arm and the RC arm, 34% and 9% of the patients had pT0, respectively (p<0.01). In subgroup analyses, OS in almost all subgroups was in favor of NAC. Conclusions: Although NAC with GC is widely used for MIBC, NAC with MVAC can still be considered promising.

Abstract
Background Surveillance after orchiectomy has recently been a management option in patients with stage I seminoma, while it remains controversial in those with stage I nonseminoma, and the risk factor associated with relapse is still a matter of concern in both entities. This study was performed to explore pathological risk factors for post-orchiectomy relapse in patients with stage I seminoma and nonseminoma, and to assess oncological outcomes in those managed with surveillance. Methods In this single institution study, 118 and 40 consecutive patients with stage I seminoma and nonseminoma were reviewed, respectively. Of the 118 patients with stage I seminoma, 56 and one received adjuvant radiotherapy and chemotherapy, respectively, and 61 were managed with surveillance. Of the 40 men with stage I nonseminoma, 4 underwent adjuvant chemotherapy and 36 were managed with surveillance. Results No patient had cause-specific death during the mean observation period of 104 and 99 months in men with seminoma and nonseminoma, respectively. In men with stage I seminoma, 1 (1.7%) receiving radiotherapy and 4 (6.6%) men managed with surveillance had disease relapse; the 10-year relapse-free survival (RFS) rate was 93.4% in men managed with surveillance, and their RFS was not different from that in patients receiving adjuvant radiotherapy (logrank P=0.15). Patients with tunica albuginea involvement showed a poorer RFS than those without (10-year RFS rate 80.0% vs. 94.1%), although the difference was of borderline significance (P=0.09). In men with stage I nonseminoma, 9 (22.5%) patients experienced relapse. Patients with lymphovascular invasion seemingly had a poorer RFS than those without; 40.0% and 18.7% of the patients with and without lymphovascular invasion had disease relapse, respectively, although the difference was not significant (logrank P=0.17). Conclusion In both men with stage I seminoma and nonseminoma, surveillance after orchiectomy is a feasible option. However, disease extension through tunica albuginea might be a factor associated with disease relapse in patients with organ-confined seminoma, and those with stage I nonseminoma showing lymphovascular invasion may possibly be at high risk for disease relapse.

Abstract
249 Background: Cisplatin-based NAC for patients (pts) with invasive BC is considered to provide a 5–8% overall survival (OS) advantage, although several studies failed to prove the survival benefit of NAC. Methods: Eligibility criteria included histologically proven urothelial carcinoma, invasive (T2-4aN0M0) bladder cancer within 8 weeks from TURBT, PS 0-1, age 20 to 75 years old. Patients were randomized to receive either 2 cycles of neoadjuvant MVAC followed by RC (NAC arm) or RC alone (RC arm). MVAC comprised M (30 mg/m2) on days 1, 15, and 22; V (3 mg/m2) on days 2, 15, and 22; A (30 mg/m2) on day 2; C (70 mg/m2) on day 2. The primary endpoint was OS. Secondary endpoints were progression-free survival (PFS), the surgery-related complication rate, adverse events during NAC, the rate of no residual tumor in the RC specimens (pT0), and quality of life. The sample size was 180 pts in each arm with a one-sided alpha of 5% and a power of 80% to detect a difference in 5-year OS from 45% in the RC arm to 57% in the NAC arm. Results: From March 2003 to March 2009, 130 pts were randomized to the NAC arm (n=64) and RC arm (n=66). The patient registration was terminated early because of slow accrual. At the second interim analysis conducted after the completion of patient accrual, the OS of the NAC arm was better than that of the RC arm (median, 102 and 81 months, respectively), although the difference was not statistically significant (HR, 0.65; multiplicity adjusted 99.99%CI, 0.19 - 2.18; one-sided log-rank p = 0.07). Considering the current situation in which NAC with gemcitabine and cisplatin (GC) is widely used in clinical practice, the Data and Safety Monitoring Committee recommended early publication of the results. The median PFS times in the RC arm and NAC arm were 78 and 99 months, respectively (p=0.04). No differences in perioperative complications, other than lymph leakage, were observed between the groups. pT0 in the NAC arm and RC arm was 34 % vs. 9 %, respectively (p<0.01). Conclusions: Although NAC with GC is widely used for invasive BC, NAC with MVAC can still be considered promising. Clinical trial information: 000000093.
