Abstract
In competitive matches, strategic decisions and emotional control are important. Relevant cognitive functions and corresponding neural activities in simple and short-term laboratory tasks have been reported. Brain resources are intensively allocated in the frontal cortex during strategic decision-making. The suppression of the frontal cortex with alpha-synchronization optimizes emotional control. However, no studies have reported the contribution of neural activity to the outcome of a more complex and prolonged task. To clarify this issue, we focused on a fighting video game following a two-round first-pass system. Frontal high-gamma and alpha power in the first and third pre-round periods, respectively, were found to be increased in a winning match. Furthermore, inter-participant variations in the importance of strategic decisions and emotional control in the first and third pre-round periods were correlated with frontal high-gamma and alpha power, respectively. Therefore, the psychological and mental state, involving frontal neural fluctuations, is predictive of match outcome.

Abstract
How do humans blink while driving a vehicle? Although gaze control patterns have been previously reported in relation to successful steering, eyeblinks that disrupt vision are believed to be randomly distributed during driving or are ignored. Herein, we demonstrate that eyeblink timing shows reproducible patterns during real formula car racing driving and is related to car control. We studied three top-level racing drivers. Their eyeblinks and driving behavior were acquired during practice sessions. The results revealed that the drivers blinked at surprisingly similar positions on the courses. We identified three factors underlying the eyeblink patterns: the driver's individual blink count, lap pace associated with how strictly they followed their pattern on each lap, and car acceleration associated with when/where to blink at a moment. These findings suggest that the eyeblink pattern reflected cognitive states during in-the-wild driving and experts appear to change such cognitive states continuously and dynamically.

Abstract
Formula car racing is highly competitive and induces significant physical stress. Previous studies have shown that intense physical stresses, such as g-force, accelerate the driver's heart rate (HR). In contrast, it remains unclear whether psychological stress affects the physiological states of racers and racing performance. To investigate this phenomenon, we developed a wearable monitor that can track the driver's HR during a race. The HR and driving performance of two professional drivers were monitored in real racing situations. Changes in HR were then evaluated based on changes in the racing situation and car behavior. The results suggest that HR acceleration is strongly correlated with race situations such as free practice or qualifying sessions, and that such changes are related to subsequent driving performance.

Abstract
Elite athletes achieve superior performance under high pressure in competitive situations. Although it is known that such situations affect the precompetitive activity of their autonomic nervous system (ANS), the relationship between precompetitive ANS activity and performance remains controversial. Especially in extreme sports, it has been shown that cardiac sympathetic tone occurs in athletes before competition attempts. However, the relationship between precompetitive sympathetic tone and performance is unclear. To investigate this relationship in extreme sports, we organized a freestyle snowboard jumping competition and examined competitors' physiological states and performance during this event. The electrocardiograms (ECGs) of 20 elite snowboarders were measured 10 min before each jump in different competitive situations: practice, qualifying, and final sessions. The mean heart rate (HR), the low-frequency to high-frequency component ratio (LF/HF ratio), the logarithm of the HF (lnHF) component of the frequency-domain of the heart rate variability (HRV), the ratio of the standard deviation of all R-R intervals to the root mean square of successive differences of R-R intervals (SDNN/rMSSD ratio), and the rMSSD of the time-domain of the HRV were calculated from the ECG data. The results showed a significant increase in the mean HR as well as significant decreases in the lnHF component and rMSSD of the HRV as the sessions progressed. Interestingly, the mean HR, LF/HF ratio and SDNN/rMSSD ratio of the HRV showed significant positive correlations with competitive scores, and the lnHF component and rMSSD of the HRV showed significant negative correlations with the scores. Our results indicate that precompetitive ANS activity becomes predominantly sympathetic in elite extreme athletes, such as freestyle snowboarders, when the competition intensifies, and that this sympathetic predominance is positively related to competitive performance.

Abstract
Excellent athletic performance in baseball and softball batting is achieved through the momentary cognitive-motor processes. However, in previous studies, cognitive and motor processes are investigated separately. In this study, we focused on the difference in the time of swing onset (a delta onset) during a batting task where 17 elite female softball batters hit balls randomly thrown at two different speeds by pitchers. The delta onset included both cognitive and motor processes because the batters needed to anticipate the ball speed and discriminate their swing motion according to the time-to-contact. Then, we investigated the relationship between the delta onset and the batting outcomes of the batting task, and the relationship between the experimental outcomes and actual batting performance (batting average) over a season. We used path analysis to clarify the structure of the cognitive-motor processes and consequent performance. We found that the batters who had a larger delta onset attained superior batting outcomes (i.e., higher exit velocity and lower miss ratio) in the batting task, and these experimental outcomes explained 67% of the batting average in real games. On the other hand, the cognitive scores (judgement accuracy and rapidity) obtained from a button pressing task, where batters responded to a ball by pressing a button instead of actually swinging, explained only 34% of the batting average. Therefore, our model quantitatively describes the key cognitive-motor structure for athletes and can partially predict a batter's performance in real games. These findings suggest that it is important to employ both cognitive and motor processes in performing tasks, such as this batting task, to properly evaluate a batter's actual ability.

Abstract
PURPOSE This study evaluated the efficacy and safety of nivolumab treatment beyond progressive disease (PD) in non-small cell lung cancer (NSCLC). PATIENTS/METHODS Medical records of consecutive patients with advanced NSCLC who received nivolumab between December 2015 and December 2018 were reviewed. Clinical outcomes of three groups of eligible patients who received nivolumab as a second-line treatment after PD were compared based on Response Evaluation Criteria in Solid Tumors v1.1. We conducted subgroup analyses in patients with and without new lesions at first PD. RESULTS Twenty-eight patients continued nivolumab treatment beyond PD (TBP). Post PD, 46 patients switched to other anti-cancer treatment (OAT), and 21 received no further anti-cancer treatment (NAT). There were no significant differences in overall survival (OS) or survival post progression (SPP) between TBP and OAT groups (OS: 15.6 vs. 13.4 months, P = .40, SPP: 12.2 vs. 9.3 months, P = .42). Subgroup analyses indicated that among patients without new lesions at first PD, SPP was longer in the TBP than in the OAT groups (12.6 vs. 9.3 months, P = .22, HR: 0.64; 95% CI 0.31‒1.31). The frequency of immune-related adverse events leading to discontinuation during nivolumab beyond PD was equivalent to that for pre-PD (10.7 vs. 12.6%). CONCLUSIONS No significant benefits were associated with continuation of nivolumab for advanced NSCLC patients. Continuation of nivolumab beyond PD could be a more useful option in patients without new lesions at first PD. Treatment-related toxicities require attention during nivolumab treatment not only before PD but also beyond PD.

Abstract
Athletes in all sports face injury or illness if they train too much. Therefore, it is crucial for them to manage their training load. Monitoring the heart rate is one way to estimate training load. However, there are limitations to a monitor's measurement ability in contact sports like rugby. Another method to estimate training load in contact sports is the rating of perceived exertion of a player, which is based on a questionnaire. It however takes a long time to obtain answers to questionnaires in team sports. As a solution to this problem, we developed a wearable heart rate monitor for rugby players. The garment-type monitor with flank electrodes can measure the heart rate even in rugby training situations. We also propose a method to estimate the training load from the measured heart rate. The method can be used instead of a questionnaire administered to the players and can reduce the labor in the estimation of the training load.

Abstract
We report on a human small cell lung cancer subline (H69/OA100) resistant to okadaic acid, an inhibitor of protein phosphatases. H69/OA100 showed cross-resistance to cis-diamminedichloroplatinum(II) (CDDP), adriamycin, and vinca alkaloids. Intracellular retention of adriamycin and CDDP in H69/OA100 was the same as those in H69. H69/OA100 was not shown to express MDR-1 by the reverse transcription polymerase chain reaction method. Expression level of mRNA of multidrug resistance-associated protein (MRP) in H69/OA100 was the same as that in H69. These data suggest that the mechanism of drug resistance in H69/OA100 might be due to a new mechanism of non-P-glycoprotein mediated multidrug resistance.

Abstract
BACKGROUND We conducted a feasibility study of induction chemotherapy followed by gefitinib and thoracic radiotherapy (TRT) for unresectable locally advanced adenocarcinoma of the lung. PATIENTS AND METHODS Patients received induction chemotherapy with cisplatin (80 mg/m(2), days 1 and 22) and vinorelbine (25 mg/m(2), days 1, 8, 22, and 29) followed by gefitinib (250 mg daily, beginning on day 43, for 1 year) and TRT (60 Gy/30 fractions, days 57-98). The primary end point was feasibility, which was defined as the proportion of patients who completed 60 Gy of TRT and received >75% of the planned dose of gefitinib without developing grade 2 or worse pneumonitis. RESULTS Of the 38 enrolled patients, 23 patients [60.5% ; 80% confidence interval (CI) 48.8-71.3] completed treatment without experiencing grade 2 or worse pneumonitis. During the chemoradiation phase, grade 3-4 alanine aminotransferase elevations were observed in 37.1% of the patients. The overall response rate was 73.0% . The median survival time was 28.5 months (95% CI 22.5-38.2), and the 2-year survival rate was 65.4% . CONCLUSIONS Although the results did not meet our criterion for feasibility, the toxicity was acceptable. This treatment warrants further evaluation among patients with locally advanced non-small-cell lung cancer harboring epidermal growth factor receptor mutations.

Abstract
Vision and proprioception contribute to generating hand movement. If a conflict between the visual and proprioceptive feedback of hand position is given, reaching movement is disturbed initially but recovers after training. Although previous studies have predominantly investigated the adaptive change in the motor output, it is unclear whether the contributions of visual and proprioceptive feedback controls to the reaching movement are modified by visuomotor adaptation. To investigate this, we focused on the change in proprioceptive feedback control associated with visuomotor adaptation. After the adaptation to gradually introduce visuomotor rotation, the hand reached the shifted position of the visual target to move the cursor to the visual target correctly. When the cursor feedback was occasionally eliminated (probe trial), the end point of the hand movement was biased in the visual-target direction, while the movement was initiated in the adapted direction, suggesting the incomplete adaptation of proprioceptive feedback control. Moreover, after the learning of uncertain visuomotor rotation, in which the rotation angle was randomly fluctuated on a trial-by-trial basis, the end-point bias in the probe trial increased, but the initial movement direction was not affected, suggesting a reduction in the adaptation level of proprioceptive feedback control. These results suggest that the change in the relative contribution of visual and proprioceptive feedback controls to the reaching movement in response to the visuomotor-map uncertainty is involved in visuomotor adaptation, whereas feedforward control might adapt in a manner different from that of the feedback control.

Abstract
Cancer cell resistance to paclitaxel continues to be a major clinical problem. In this study, we utilized microRNA (miRNA) arrays to screen for differentially expressed miRNAs in paclitaxel-resistant cell lines established in vitro. We observed concordant upregulation of miR-135a in paclitaxel-resistant cell lines representing three human malignancies. Subsequently, the role of miRNA-135a was evaluated in an in vivo model of paclitaxel resistance. In this model, mice were inoculated subcutaneously with a non-small cell lung carcinoma cell line and treated with paclitaxel for a prolonged period. In paclitaxel-resistant cell lines, established either in vitro or in vivo, blockage of miR-135a sensitized resistant cell lines to paclitaxel-induced cell death. We further demonstrated a correlation between paclitaxel response and miR-135a expression in paclitaxel-resistant subclones that were established in vivo. The paclitaxel-resistant phenotype of these subclones was maintained upon retransplantation in new mice, as shown by decreased tumor response upon paclitaxel treatment compared with controls. Upregulation of miR-135a was associated with reduced expression of the adenomatous polyposis coli gene (APC). APC knockdown increased paclitaxel resistance in parental cell lines. Our results indicate that paclitaxel resistance is associated with upregulation of miR-135a, both in vitro and in vivo, and is in part determined by miR-135a-mediated downregulation of APC.

Abstract
BACKGROUND This study aimed to evaluate the safety and efficacy of dose-dense weekly chemotherapy, followed by resection and/or thoracic radiotherapy. METHODS Patients with histologically documented thymoma with unresectable stage III disease received 9 weeks of chemotherapy: cisplatin 25 mg m(-2) on weeks 1-9; vincristine 1 mg m(-2) on weeks 1, 2, 4, 6 and 8; and doxorubicin 40 mg m(-2) and etoposide 80 mg m(-2) on days 1-3 of weeks 1, 3, 5, 7 and 9. Patients went on to surgery and post-operative radiotherapy of 48 Gy; those with unresectable disease received 60 Gy radiotherapy. RESULTS total of 23 patients were entered. The main toxicities of the chemotherapy regimen were neutropenia and anaemia, and 57% of patients completed the planned 9 weeks of therapy. There were no toxic deaths. Of the 21 eligible patients, 13 (62%) achieved a partial response (95% confidence interval: 38-82%). Thirteen patients underwent a thoracotomy and nine (39%) underwent complete resection. Progression-free survival at 2 and 5 years was 80 and 43%, respectively. Overall survival at 5 and 8 years was 85 and 69%, respectively. Survival did not seem to be affected by resection. CONCLUSION In thymoma patients, weekly dose-dense chemotherapy has activity similar to that of conventional regimens. Although some patients could achieve complete resection, the role of surgery remains unclear.

Abstract
BACKGROUND To evaluate the safety and efficacy of dose-dense weekly chemotherapy in the treatment of advanced thymoma. METHODS Subjects comprised patients with histologically documented chemotherapy-naïve thymoma with stage-IVa or IVb disease. Thymic carcinoma, carcinoid or lymphoma cases were excluded. Patients received 9 weeks of chemotherapy: cisplatin (25 mg m(-2)) on weeks 1-9; vincristine (1 mg m(-2)) on weeks 1, 2, 4, 6 and 8; and doxorubicin (40 mg m(-2)) and etoposide (80 mg m(-2)) on days 1-3 of weeks 1, 3, 5, 7 and 9. Chemotherapy courses were supported by granulocyte colony-stimulating factor. Post-protocol local therapy was allowed. RESULTS From July 1997 to March 2004, 30 patients were entered. Three were ineligible due to different histology. Chemotherapy-associated toxicity was mainly haematological and was well tolerated, with no deaths due to toxicity, and 87% of patients completed the planned 9-week regimen. Overall response rate was 59%, with 16 of the 27 eligible patients achieving partial response. Median progression-fee survival (PFS) was 0.79 years (95% confidence interval: 0.52-1.40 years), and PFS at 1 and 2 years was 37 and 15%, respectively. Overall survival rates at 2 and 5 years were 89 and 65%, respectively. CONCLUSION In stage-IV thymoma patients, weekly dose-dense chemotherapy offers similar activity to conventional regimens.

Abstract
BACKGROUND The mechanism of resistance to human epidermal growth factor receptor 2 (HER2)-targeted agents has not been fully understood. We investigated the influence of PIK3CA mutations on sensitivity to HER2-targeted agents in naturally derived breast cancer cells. MATERIALS AND METHODS We examined the effects of Calbiochem (CL)-387,785, HER2 tyrosine kinase inhibitor, and trastuzumab on cell growth and HER2 signaling in eight breast cancer cell lines showing HER2 amplification and trastuzumab-conditioned BT474 (BT474-TR). RESULTS Four cell lines with PIK3CA mutations (E545K and H1047R) were more resistant to trastuzumab than the remaining four without mutations (mean percentage of control with 10 microg/ml trastuzumab: 58% versus 92%; P = 0.010). While PIK3CA-mutant cells were more resistant to CL-387,785 than PIK3CA-wild-type cells (mean percentage of control with 1 microM CL-387,785: 21% versus 77%; P = 0.001), CL-387,785 retained activity against BT474-TR. Growth inhibition by trastuzumab and CL-387,785 was more closely correlated with changes in phosphorylation of S6K (correlation coefficient, 0.811) than those of HER2, Akt, or ERK1/2. Growth of most HER2-amplified cells was inhibited by LY294002, regardless of PIK3CA genotype. CONCLUSIONS PIK3CA mutations are associated with resistance to HER2-targeted agents. PI3K inhibitors are potentially effective in overcoming trastuzumab resistance caused by PIK3CA mutations. S6K phosphorylation is a possibly useful pharmacodynamic marker in HER2-targeted therapy.

Abstract
CRA8003 Background: Vandetanib is a once-daily oral inhibitor of VEGFR, EGFR and RET signaling. Addition of vandetanib to docetaxel (doc) prolonged progression-free survival (PFS) in a randomized phase II study in patients (pts) with previously treated NSCLC (Heymach et al, JCO, 2007). Methods: The primary objective was to determine whether vandetanib 100 mg/day + doc 75 mg/m2 every 21 days (max 6 cycles) prolonged PFS vs placebo + doc. Secondary endpoints included overall survival, objective response rate (ORR), time to deterioration of symptoms (TDS) and safety. Efficacy and safety in females were assessed as a co-primary analysis population. Eligibility criteria included stage IIIB/IV NSCLC, PS 0–1, and previous first-line chemotherapy. Results: Between May 2006 and April 2008, 1,391 pts (mean age, 58 years; 30% female; 25% squamous; 10% brain mets) were randomized to vandetanib + doc (n=694) or placebo + doc (n=697). Baseline characteristics were similar in both arms. Median duration of follow-up was 12.8 months, with 87% patients progressed and 59% dead. Addition of vandetanib to doc showed a statistically significant improvement in PFS vs doc (hazard ratio [HR] 0.79, 97.58% CI 0.70–0.90; P<0.001), and a similar advantage in females (HR 0.79; P=0.024). Significant advantages for vandetanib + doc were also seen for ORR (17% vs 10%, P<0.001) and TDS (HR 0.78, P=0.002; FACT-L Lung Cancer Subscale). Overall survival showed a positive trend for vandetanib + doc that was not statistically significant (HR 0.91, 97.52% CI 0.78–1.07; P=0.196). The adverse event (AE) profile was consistent with that previously observed for vandetanib in NSCLC. Common AEs occurring more frequently in the vandetanib arm included diarrhea (42% vs 33%), rash (42% vs 24%) and neutropenia (32% vs 27%). Nausea (23% vs 32%), vomiting (16% vs 21%) and anemia (10% vs 15%) were less frequent in the vandetanib arm. The incidence of protocol-defined QTc prolongation was <2% in pts receiving vandetanib. Conclusions: The study met its primary objective of PFS prolongation with vandetanib + doc vs doc. Vandetanib is the first oral targeted therapy in phase III trials to show significant evidence of clinical benefit when added to standard chemotherapy in NSCLC. [Table: see text]

Abstract
8094 Background: EGFR mutation is both a predictive and prognostic factor for NSCLC treated with EGFR-TKI. Although new, highly sensitive methods for detecting EGFR mutations are currently available, these methods have not been validated. Methods: To validate direct sequencing and PCR-invader for detecting EGFR mutation, we analyzed 124 NSCLC by both methods concomitantly. Tumor tissues were obtained by surgical resection. Formalin-fixed paraffin-embedded specimens were prepared to analyze EGFR mutation. In direct sequencing, Exon 18, 19, and 21 of the EGFR gene were amplified, and PCR amplification products were sequenced directly (Mitsubishi Chemical Medience Corporation). PCR-invader was performed using the invasive cleavage of probe oligonucleotides to detect 10 mutations including Exon 18, 19, 20, 21 (BML incorporation). Results: EGFR mutations were detected in 51 patients (41%) by direct sequencing and 56 (45%) by PCR-invader. Discordance between two methods was found in 12 patients (10%). Exon 19 deletion was detected in 18 and 22 patients respectively. Exon 21 L858R was detected in 30 and 32 patients respectively. Each mutation in exon 19 deletions or L858R detected by direct sequencing could also be identified by PCR-invader. Overall 45 mutations were concordant by both methods. In two patients who received gefitinib, one patient with wild type by both methods did not respond to gefitinib. On the other hand, the other patient expressing Exon 19 deletion by PCR-invader but regarded as wild type by direct sequencing responded to gefitinib monotherapy. Conclusions: Discrepancy between two methods for detecting EGFR mutation was demonstrated and PCR-invader seems to be more sensitive. Further investigation including other highly sensitive methods is currently underway. No significant financial relationships to disclose.
