Abstract
Samples of the carbonaceous asteroid Ryugu were brought to Earth by the Hayabusa2 spacecraft. We analyzed 17 Ryugu samples measuring 1 to 8 millimeters. Carbon dioxide-bearing water inclusions are present within a pyrrhotite crystal, indicating that Ryugu's parent asteroid formed in the outer Solar System. The samples contain low abundances of materials that formed at high temperatures, such as chondrules and calcium- and aluminum-rich inclusions. The samples are rich in phyllosilicates and carbonates, which formed through aqueous alteration reactions at low temperature, high pH, and water/rock ratios of <1 (by mass). Less altered fragments contain olivine, pyroxene, amorphous silicates, calcite, and phosphide. Numerical simulations, based on the mineralogical and physical properties of the samples, indicate that Ryugu's parent body formed ~2 million years after the beginning of Solar System formation.

Abstract
The Hayabusa2 spacecraft investigated the C-type (carbonaceous) asteroid (162173) Ryugu. The mission performed two landing operations to collect samples of surface and subsurface material, the latter exposed by an artificial impact. We present images of the second touchdown site, finding that ejecta from the impact crater was present at the sample location. Surface pebbles at both landing sites show morphological variations ranging from rugged to smooth, similar to Ryugu's boulders, and shapes from quasi-spherical to flattened. The samples were returned to Earth on 6 December 2020. We describe the morphology of >5 grams of returned pebbles and sand. Their diverse color, shape, and structure are consistent with the observed materials of Ryugu; we conclude that they are a representative sample of the asteroid.

Global Forum of Cancer Surgeons: Cancer Surgery During the COVID-19 Pandemic: Impact and Lessons Learned. Ann Surg Oncol 2022; 29:2773-2783. [PMID: 35211857 PMCID: PMC8870071 DOI: 10.1245/s10434-022-11506-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2021] [Accepted: 02/14/2022] [Indexed: 11/18/2022]
Abstract
Background The purpose of this article is to summarize the opinions of the surgical oncology leaders from the Global Forum of Cancer Surgeons (GFCS) about the global impact of COVID-19 pandemic on cancer surgery. Methods A panel session (virtual) was held at the annual Society of Surgical Oncology 2021 International Conference on Surgical Cancer Care to address the impact of COVID-19 on cancer surgery globally. Following the virtual meeting, a questionnaire was sent to all the leaders to gather additional opinions. The input obtained from all the leaders was collated and analyzed to understand how cancer surgeons from across the world adapted in real-time to the impact of COVID-19 pandemic. Results The surgical oncology leaders noted that the COVID-19 pandemic led to severe disruptions in surgical cancer care across all domains of clinical care, education, and research. Several new changes/protocols associated with increased costs were implemented to deliver safe care. Leaders also noted that preexisting disparities in care were exacerbated, and the pandemic had a detrimental effect on well-being and financial status. Conclusions The COVID-19 pandemic has led to severe disruptions in surgical cancer care globally. Leaders of the GFCS opined that new strategies need to be implemented to prepare for any future catastrophic events based on the lessons learned from the current events. The GFCS will embark on developing such a roadmap to ensure that surgical cancer care is preserved in the future regardless of any catastrophic global events.

Neurological outcomes of out-of-hospital cardiac arrest occurring in Tokyo train and subway stations. Resusc Plus 2021; 8:100175. [PMID: 34816139 PMCID: PMC8591414 DOI: 10.1016/j.resplu.2021.100175] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2021] [Revised: 10/04/2021] [Accepted: 10/05/2021] [Indexed: 11/20/2022] Open
Abstract
Objectives The purpose of this study was to identify a relationship between the background environment, bystander and emergency medical services intervention, and favourable neurological outcomes (CPC1-2) one-month after out-of-hospital cardiac arrest (OHCA) occurred at Tokyo train and subway stations. Methods This retrospective observational study used OHCA data between 2014 and 2018 that occurred at train stations in Tokyo. The eligible 954 patients were analysed for correlation between background, time frame, and location. Multivariable logistic regression models were used to estimate factors associated with CPC1-2 in patients with cardiogenic OHCA. Results A total of 886 OHCA cases, cardiogenic (n=562) and non-cardiogenic (n=324), met the inclusion criteria. Of the cardiogenic cases, 71.9% occurred at the platform and on-a-train. One-month CPC1-2 was achieved in 32.0% of cardiogenic OHCAs, which included 47.3% during morning rush hour, 24.7% during daytime hours, 40.2% during evening rush hour, and 20.5% during night-time/early morning hours. CPC1-2 had significant correlation with morning rush hour (adjusted odds ratio [AOR],4.52; 95% confidence interval [CI], 1.09–18.78), evening rush hour (AOR, 6.85; 95% CI, 1.51–31.15), public access defibrillation (AOR, 5.19; 95% CI, 1.38–19.51), and ventricular fibrillation or pulseless ventricular tachycardia (AOR, 7.56; 95% CI, 1.35–42.43). Conclusion A total of 71.9% of cardiogenic OHCAs occurred at platforms and on trains. To improve neurological outcomes of OHCAs at stations, AED installations on train platforms are necessary. Additionally, using artificial intelligence-based platform monitoring for early detection of OHCAs and offering CPR training are required.

Effects of an elemental diet to reduce adverse events in patients with esophageal cancer receiving docetaxel/cisplatin/5-fluorouracil: a phase III randomized controlled trial-EPOC 2 (JFMC49-1601-C5). ESMO Open 2021; 6:100277. [PMID: 34626918 PMCID: PMC8511839 DOI: 10.1016/j.esmoop.2021.100277] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2021] [Revised: 09/03/2021] [Accepted: 09/07/2021] [Indexed: 01/11/2023] Open
Abstract
Background Oral mucositis (OM) is an unpleasant adverse event in patients receiving chemotherapy. A prospective feasibility study showed that elemental diet (ED), an oral supplement that does not require digestion, may prevent OM. Based on this, we established a central review system for oral cavity assessment by dental oncology specialists blinded to background data. We used this system to elucidate the preventive effect of an ED against OM in patients with esophageal cancer receiving docetaxel, cisplatin, and 5-fluorouracil (DCF) therapy. Patients and methods In this phase III, multicenter, parallel-group, controlled trial, patients consuming a normal diet orally were randomly assigned (1 : 1) to receive two cycles of DCF with (group A) or without (group B) an ED (Elental® 160 g/day). We assessed the incidence of grade ≥2 OM evaluated by two reviewers, changes in body weight, prealbumin, C-reactive protein, and DCF completion rate based on ED compliance. Results Of the 117 patients randomly assigned to treatment, four failed to start treatment and were excluded from the primary analysis; thus, groups A and B comprised 55 and 58 patients, respectively. There were no significant differences in background characteristics. Grade ≥2 OM was observed in eight (15%) and 20 (34%) patients in groups A and B, respectively (P = 0.0141). Changes in body weight and prealbumin during the two DCF cycles were significantly higher in group A than B (P = 0.0022 and 0.0203, respectively). During the first cycle, changes in C-reactive protein were significantly lower in group A than B (P = 0.0338). In group A (receiving ED), the DCF completion rate was 100% in patients with 100% ED compliance and 70% in patients failing ED completion (P = 0.0046). Conclusions The study findings demonstrate that an ED can prevent OM in patients with esophageal cancer receiving chemotherapy. Patients receiving docetaxel, cisplatin, and 5-fluorouracil (DCF) chemotherapy commonly develop oral mucositis (OM). An elemental diet (ED) was able to prevent OM in patients with esophageal cancer receiving DCF. Grade ≥2 OM was observed in 15% of patients receiving the ED versus 34% of those not receiving the ED (P = 0.0141). Body weight was maintained in the ED group, and hematologic toxicities were lower, compared with the non-ED group. The DCF completion rate significantly correlated with ED compliance (P = 0.0046).

Abstract
The incidence of hyperglycemia and diabetes induced by everolimus has been shown in previous studies. Our study analyzed diabetes time-to-onset profiles after everolimus use in patients who underwent transplantation and patients with cancer. Using data from April 2007 to December 2018 in the Japanese Adverse Drug Event Report database, the reports with everolimus were classified according to its use as an immunosuppressant or anticancer drug. The median (25%-75%) days of diabetes time-to-onset in patients who underwent transplantation and patients with cancer were 172 (56-315) and 32 (18.5-57), respectively. There were no significant variations among patients with breast cancer, neuroendocrine tumor, and renal cell carcinoma. By conducting a Weibull shape parameter test, the lower limits of the 95% confidence intervals of the shape parameter β values for the indications of the cancer types were >1, indicating the wear out failure type profile, whereas those for transplantation data indicated a random failure type profile. The diabetes time-to-onset profiles after everolimus use differed between usage as an anticancer drug and immunosuppressant and there were no significant variations among the type of cancer. It was suggested that the incidence of diabetes should be monitored for 1-2 months in patients with cancer, whereas continuous monitoring is needed in patients who undergo transplantation.

Abstract
OBJECTIVE: To retrospectively evaluate the clinical outcomes of pre-operative endovascular coil embolisation (ECE) for chronic pulmonary aspergillosis (CPA).METHODS: We evaluated surgical patients with CPA between November 2016 and April 2020. Pre-operative ECE for CPA with severe adhesions was selectively performed to reduce intra-operative blood loss. ECE procedures, operative procedures, intra-operative blood loss and complications were evaluated.RESULTS: Twenty-eight patients (21 males and 7 females; median age: 55 years) were included in the study. Of the 28 patients, 8 (28.6%) underwent pre-operative ECE. Technical success rate in pre-operative ECE was 100%. The median time required for ECE procedures was 123 min. The median number of vessels embolised per procedure was 2.5. The median period between embolisation and surgery was 5 days. Major complications were observed in three patients (10.7%). There were no significant differences between patients with and without pre-operative ECE in operative time (284 vs. 365 min, respectively, P = 0.7602) and intra-operative blood loss (294 vs. 228 mL, respectively, P = 0.8987).CONCLUSIONS: Pre-operative ECE for CPA appears to be feasible and safe; however, its role in reducing intra-operative blood loss needs further investigation.

Abstract
In the therapeutic management of eosinophilic disorder, it is important to prevent hypereosinophilia (HE)-related organ damage even in the process of diagnosis. We describe here a unique clinical and histopathological findings of the patient with HE accompanied with digital ischaemia. Treatment with intravenous prostaglandin E1 was essential for digital ischaemia in our case while benralizumab, humanized monoclonal antibody against interleukin-5 receptorα, did not affect. Our case suggests an earlier intervention for digital ischaemia in the therapeutic management of eosiniphilic disorder.

Abstract
We find a novel topological defect in a spin-nematic superfluid theoretically. A quantized vortex spontaneously breaks its axisymmetry, leading to an elliptic vortex in nematic-spin Bose-Einstein condensates with small positive quadratic Zeeman effect. The new vortex is considered the Joukowski transform of a conventional vortex. Its oblateness grows when the Zeeman length exceeds the spin healing length. This structure is sustained by balancing the hydrodynamic potential and the elasticity of a soliton connecting two spin spots, which are observable by in situ magnetization imaging. The theoretical analysis clearly defines the difference between half quantum vortices of the polar and antiferromagnetic phases in spin-1 condensates.

Abstract
OBJECTIVE Synthetic glucocorticoids cause various psychiatric symptoms. Prescription of psychotropic drugs could be considered to be a proxy for manifestation of psychiatric symptoms. The aim of this study was to investigate the prescriptions of psychotropics in outpatients receiving synthetic glucocorticoids. METHODS We used the claims sampling data during January 2015 from the National Database of Health Insurance Claims and Specific Health Checkups of Japan made by the Ministry of Health, Labor, and Welfare in Japan. We compared the prescription rates of psychotropics between outpatients receiving oral synthetic glucocorticoids and age- and sex-matched controls and the prescription rates of psychotropics among the eight dosage groups of synthetic glucocorticoids by chi-squared test, and chlorpromazine/imipramine/diazepam equivalent doses (or daily defined doses) of respective psychotropics among these groups using Welch's t-test. RESULTS Synthetic glucocorticoids were prescribed to 3.1% (n = 18 122) of 581 990 patients. The prescription rates of psychotropics were significantly higher among the synthetic glucocorticoid recipients than among the non-recipients: antipsychotics, 1.8% (n = 321) vs. 1.1% (n = 201) (P = 1.4 × 10-7 ); antidepressants, 4.0% (n = 724) vs. 2.0% (n = 359) (P = 8.7 × 10-30 ); anxiolytics/hypnotics, 16.7% (n = 3029) vs. 10.2% (n = 1841) (P = 2.7 × 10-75 ); and mood stabilizers, 1.3% (n = 238) vs. 0.7% (n = 120) (P = 3.6 × 10-10 ) respectively. There was no significant difference in the prescription rates of any psychotropic drugs, other than anxiolytics/hypnotics, among the eight synthetic glucocorticoid dosage groups. CONCLUSION Prescriptions of oral synthetic glucocorticoids were found to be associated with the use of any of the types of psychotropic drugs, other than anxiolytics/hypnotics, although a causal relationship could not be confirmed due to the retrospective and cross-sectional nature of this study.

Abstract
BACKGROUND To date, there have been no studies evaluating adherence to clozapine with electronic adherence monitoring (EAM) such as the Medication Event Monitoring System (MEMS® ). METHODS In outpatients with schizophrenia, we conducted a 3-month prospective study investigating antipsychotic adherence with EAM (eCAP® ). Participants were treated with different oral antipsychotics, including clozapine, and blind to EAM monitoring; all were on antipsychotic monotherapy administered once daily. Outcome measures included adherence rate, missed dose, and medication gap. Adherence trajectory patterns were also analyzed for clozapine vs. other antipsychotics collectively. RESULTS A total of 111 patients were included in the study; 33 and 78 patients received clozapine or other antipsychotics, respectively. Adherence rates, defined as proportion of days that the subject took the medication at the prescribed time ± 3 h and proportion of subjects with ≥80% adherence, were numerically higher in patients receiving clozapine vs. other antipsychotics (72.0% vs. 65.1%, P = 0.10; 49.5% vs. 35.7%, P = 0.11, respectively). Along similar lines, some of the missed dose and medication gap outcomes were significantly better in patients receiving clozapine vs. other antipsychotics. Three adherence trajectory patterns were identified for both clozapine and other antipsychotics, with two shared by both groups (i.e., low adherence with a slight decrease over time; high and stable adherence). CONCLUSION Findings suggest that in patients with schizophrenia clozapine adherence is at least comparable, if not slightly better, compared with other antipsychotics.

Abstract
The Hayabusa2 spacecraft investigated the small asteroid Ryugu, which has a rubble-pile structure. We describe an impact experiment on Ryugu using Hayabusa2's Small Carry-on Impactor. The impact produced an artificial crater with a diameter >10 meters, which has a semicircular shape, an elevated rim, and a central pit. Images of the impact and resulting ejecta were recorded by the Deployable CAMera 3 for >8 minutes, showing the growth of an ejecta curtain (the outer edge of the ejecta) and deposition of ejecta onto the surface. The ejecta curtain was asymmetric and heterogeneous and it never fully detached from the surface. The crater formed in the gravity-dominated regime; in other words, crater growth was limited by gravity not surface strength. We discuss implications for Ryugu's surface age.

Abstract
BACKGROUND Oesophageal squamous cell carcinoma is an aggressive disease owing to early and widespread lymph node metastases. Multimodal therapy and radical surgery may improve prognosis. Few studies have investigated the efficacy of radical lymph node and thoracic duct resection. METHODS Patients with oesophageal squamous cell carcinoma who underwent transthoracic minimally invasive oesophagectomy (TMIE) for cancer at Keio University Hospital between January 2004 and December 2016 were selected. Between 2004 and 2008, TMIE was performed in the lateral decubitus position without thoracic duct resection (standard TMIE). From 2009 onwards, TMIE with extended lymph node and thoracic duct resection was introduced (extended TMIE). Demographics, co-morbidity, number of retrieved lymph nodes, pathology, postoperative complications and recurrence-free survival (RFS) were compared between groups. RESULTS Forty-four patients underwent standard TMIE and 191 extended TMIE. There were no significant differences in clinical and pathological tumour stage or postoperative complications. The extended-TMIE group had more lymph nodes removed at nodal stations 106recL and 112. Among patients with cT1 N0 disease, RFS was better in the extended-TMIE group (P < 0·001), whereas there was no difference in RFS between groups in patients with advanced disease. CONCLUSION Extended TMIE including thoracic duct resection increased the number of lymph nodes retrieved and was associated with improved survival in patients with cT1 N0 oesophageal squamous cell carcinoma.

Abstract
The Hayabusa2 spacecraft arrived at the near-Earth carbonaceous asteroid 162173 Ryugu in 2018. We present Hayabusa2 observations of Ryugu's shape, mass, and geomorphology. Ryugu has an oblate "spinning top" shape, with a prominent circular equatorial ridge. Its bulk density, 1.19 ± 0.02 grams per cubic centimeter, indicates a high-porosity (>50%) interior. Large surface boulders suggest a rubble-pile structure. Surface slope analysis shows Ryugu's shape may have been produced from having once spun at twice the current rate. Coupled with the observed global material homogeneity, this suggests that Ryugu was reshaped by centrifugally induced deformation during a period of rapid rotation. From these remote-sensing investigations, we identified a suitable sample collection site on the equatorial ridge.

Abstract
The near-Earth carbonaceous asteroid 162173 Ryugu is thought to have been produced from a parent body that contained water ice and organic molecules. The Hayabusa2 spacecraft has obtained global multicolor images of Ryugu. Geomorphological features present include a circum-equatorial ridge, east-west dichotomy, high boulder abundances across the entire surface, and impact craters. Age estimates from the craters indicate a resurfacing age of [Formula: see text] years for the top 1-meter layer. Ryugu is among the darkest known bodies in the Solar System. The high abundance and spectral properties of boulders are consistent with moderately dehydrated materials, analogous to thermally metamorphosed meteorites found on Earth. The general uniformity in color across Ryugu's surface supports partial dehydration due to internal heating of the asteroid's parent body.

Abstract
We report the observation of spin domain walls bounded by half-quantum vortices (HQVs) in a spin-1 Bose-Einstein condensate with antiferromagnetic interactions. A spinor condensate is initially prepared in the easy-plane polar phase, and then, suddenly quenched into the easy-axis polar phase. Domain walls are created via the spontaneous Z_{2} symmetry breaking in the phase transition and the walls dynamically split into composite defects due to snake instability. The end points of the defects are identified as HQVs for the polar order parameter and the mass supercurrent in their proximity is demonstrated using Bragg scattering. In a strong quench regime, we observe that singly charged quantum vortices are formed with the relaxation of free wall-vortex composite defects. Our results demonstrate a nucleation mechanism for composite defects via phase transition dynamics.

Early Outcomes of Living-Donor Kidney Transplantation With Immunosuppression Therapy Induction With Tacrolimus Extended-Release: A Comparison With Cyclosporine. Transplant Proc 2018; 50:2457-2460. [PMID: 30316378 DOI: 10.1016/j.transproceed.2018.04.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2018] [Revised: 03/24/2018] [Accepted: 04/09/2018] [Indexed: 11/18/2022]
Abstract
BACKGROUND Extended-release tacrolimus (TacER), administered once daily, offers improved adherence with reduced side effects while still maintaining an immunosuppressive potency equivalent to that of conventional tacrolimus preparations. METHODS The study included 83 patients who received consecutive living-donor kidney transplants at our facility from June 2013 to December 2016. Comparisons were made between 48 cases of induction with TacER and 35 cases of induction with cyclosporine (CyA). The observation period was 3 months after transplantation. Transplanted kidney function, rejection, infectious disease, lipid abnormalities, and glucose tolerance were compared. RESULTS The 2 groups showed no significant difference in donor background or transplanted kidney function. Within the 3-month observation period, an acute rejection response was observed in 2 cases in the TacER group and in 8 cases in the CyA group. After transplantation, hyperlipidemia requiring medication was observed more frequently in the CyA group. The 2 groups did not show a marked difference in systemic infection or renal calcineurin inhibitor toxicity in histopathologic examination of the transplanted kidneys 3 months after surgery. DISCUSSION Proactive use of TacER leads to improved adherence while yielding immunosuppressive potency equivalent to that of conventional tacrolimus preparations; however, tacrolimus has a potent blood sugar-elevating effect; thus, direct comparison with the CyA group is important for assessing the side effects. CONCLUSION TacER has the potential to also reduce side effects in the early stages after surgery, suggesting its potential as a drug of first choice.

Abstract
Recurrent laryngeal nerve paralysis (RLNP) is a frequent and serious complication following esophageal cancer surgery. Therefore, this study aims to evaluate the correlation between recurrent laryngeal nerve (RLN) size and RLNP. This was a retrospective study of esophageal cancer patients who underwent thoracoscopic esophagectomy from January 2012 to December 2014. Eighty-four patients were included in the primary analysis. Diameter of the RLN was measured using the digital video recording of surgical procedures by the ratio between scissor and RLN. For evaluation of vocal cord paralysis or paresis, indirect laryngoscopy was performed. Because RLNP more frequently occurs on the left side than the right, we evaluated the correlation between size of the left RLN and left RLNP. The median size of the left RLN was 1.51 mm. We found that the incidence of postoperative left RLNP (Clavien-Dindo classification ≥1) was significantly higher (71% vs. 24%; P < 0.001) in thin RLNs (≤1.5 mm) than in thick RLNs (>1.5 mm). Thin RLN (P < 0.001), female sex (P = 0.025), and being overweight (P = 0.034) were identified as significant independent risk factors for postoperative RLNP. RLNP more easily occurred when the RLN was thin. It is difficult to confirm occurrence of postoperative RLNP before and at extubation. Therefore, it is helpful to know its risk factors including size of RLN.

Abstract
Background Oesophagectomy has a high risk of postoperative morbidity. The impact of postoperative complications on overall survival of oesophageal cancer remains unclear. This meta‐analysis addressed the impact of complications on long‐term survival following oesophagectomy. Methods A search of PubMed and Cochrane Library databases was undertaken for systematic review of papers published between January 1995 and August 2016 that analysed the relation between postoperative complications and long‐term survival. In the meta‐analysis, data were pooled. The main outcome was overall survival (OS). Secondary endpoints included disease‐free (DFS) and cancer‐specific (CSS) survival. Results A total of 357 citations was reviewed; 21 studies comprising 11 368 patients were included in the analyses. Overall, postoperative complications were associated with significantly decreased 5‐year OS (hazard ratio (HR) 1·16, 95 per cent c.i. 1·06 to 1·26; P = 0·001) and 5‐year CSS (HR 1·27, 1·09 to 1·47; P = 0·002). Pulmonary complications were associated with decreased 5‐year OS (HR 1·37, 1·16 to 1·62; P < 0·001), CSS (HR 1·60, 1·35 to 1·89; P < 0·001) and 5‐year DFS (HR 1·16, 1·00 to 1·33; P = 0·05). Patients with anastomotic leakage had significantly decreased 5‐year OS (HR 1·20, 1·10 to 1·30; P < 0·001), 5‐year CSS (HR 1·81, 1·11 to 2·95; P = 0·02) and 5‐year DFS (HR 1·13, 1·02 to 1·25; P = 0·01). Conclusion Postoperative complications after oesophagectomy, including pulmonary complications and anastomotic leakage, decreased long‐term survival.

Abstract
Abstract
Purpose: Eribulin mesylate (eribulin) is a first-in-class halichondrin B-based microtubule dynamics inhibitor. To understand the mechanism of vascular remodeling of eribulin, we compared optical hemodynamic and blood biomarker changes between eribulin and bevacizumab.
Methods: Patients with advanced breast cancer with stage III/IV were eligible for the study. Patients were assigned to receive either eribulin or single-agent bevacizumab. Diffuse optical spectroscopic imaging (DOSI) measured tissue concentrations of oxy-hemoglobin (O2Hb), deoxy-hemoglobin (HHb), total hemoglobin (tHb) and oxygen saturation (SO2) of breast tumors before and day 7 after the first infusion. Peripheral blood samples were obtained from the patients to measure plasma concentration of VEGF, bFGF, FLT-3L, EGF, G-CSF, TNFα, IL1b, IL4, IL6, IL8, IL10, IL12p40, and TGF-β1.
Results: Baseline DOSI measurement of all 29 patients (eribulin, n = 14 and bevacizumab, n = 15) revealed significantly higher tumor concentrations of O2Hb, HHb, and tHb than that in the normal breast tissue. Eribulin significantly decreased in HHb concentration and increased SO2 during the observation period. This trend was not observed for bevacizumab. Instead, bevacizumab significantly decreased the concentration of O2Hb and tHb. The blood biomarker study revealed that both eribulin and bevacizumab decreased plasma concentrations of VEGF and bFGF, but only eribulin suppressed the plasma concentration of TGF-β1.
Conclusions:
Optical imaging technology revealed that eribulin, but not bevacizumab, induced tumor reoxygenation after the start of infusion. Eribulin had a potent anti-angiogenic properties as well as bevacizumab, while suppression of TGF-β1 observed by only eribulin could be associated with remodeling of the microvasculature through suppression of activated stromal cells.

Abstract
Neoadjuvant chemotherapy (NAC) and chemoradiotherapy have been shown to extend postoperative survival, and preoperative therapy followed by esophagectomy has become the standard treatment worldwide for patients with esophageal squamous cell carcinoma (ESCC). The Japan Clinical Oncology Group 9907 study showed that NAC significantly extended survival in advanced ESCC, but the survival benefit for patients with clinical stage III disease remains to be elucidated. We compared the survival rates of NAC and upfront surgery in patients with clinical stage III ESCC. Consecutive patients histologically diagnosed as clinical stage III (excluding cT4) ESCC were eligible for this retrospective study. Between September 2002 and April 2007, upfront transthoracic esophagectomy was performed initially and, for patients with positive lymph node (LN) metastasis in a resected specimen, adjuvant chemotherapy using cisplatin and 5-fluororouracil every 3 weeks for two cycles was administered (Upfront surgery group). Since May 2007, a NAC regimen used as adjuvant chemotherapy followed by transthoracic esophagectomy has been administered as the standard treatment in our institution (NAC group). Patient characteristics, clinicopathological factors, treatment outcomes, post-treatment recurrence, and overall survival (OS) were compared between the NAC and upfront surgery groups. Fifty-one and 55 patients were included in the NAC and upfront surgery groups, respectively. The R0 resection rate was significantly lower in the NAC group than in the upfront surgery group (upfront surgery, 98%; NAC, 76%; P = 0.003). In the upfront surgery group, of 49 patients who underwent R0 resection and pathologically positive for LN metastasis, 22 (45%) received adjuvant chemotherapy. In the NAC group, 49 (96%) of 51 patients completed two cycles of NAC. In survival analysis, no significant difference in OS was observed between the NAC and upfront surgery groups (NAC: 5-year OS, 43.8%; upfront surgery: 5-year overall surgery, 57.5%; P = 0.167). Patients who underwent R0 resection showed significantly longer OS than did those who underwent R1, R2, or no resection (P = 0.001). In multivariate analysis using age, perioperative chemotherapy, depth of invasion, LN metastasis, surgical radicality, postoperative pneumonia, and anastomotic leakage as covariates, LN metastasis [cN2: hazard ratio (HR), 1.389; P = 0.309; cN3: HR, 16.019; P = 0.012] and surgical radicality (R1: HR, 3.949; P = 0.009; R2 or no resection: HR, 2.912; P = 0.022) were shown to be significant independent prognostic factors. In clinical stage III ESCC patients, no significant difference in OS was observed between NAC and upfront surgery. Although potential patient selection bias might be a factor in this retrospective analysis, the noncurative resection rate was higher after NAC than after upfront surgery. The survival benefit of more intensive NAC needs to be further evaluated.
