Abstract
BACKGROUND Epipericardial fat necrosis (EFN) is a rare disease in which local inflammation and necrosis occur in the adipose tissue surrounding the heart, particularly epicardial fat. Few cases of EFN in which surgical resection was performed have been reported. We report a case of EFN after surgical resection of a right extrapulmonary tumor, in which a malignant disease could not be excluded. CASE PRESENTATION A 75-year-old male patient presented with fever and chest pain. A contrast-enhanced computed tomography scan of the chest revealed a lesion, 53 × 48 mm in size, with mixed fatty density spanning the middle and lower lobes of the right lung. Thoracic magnetic resonance imaging (MRI) revealed a mass with mixed fat and soft tissue density in the same area; the lesion was contiguous with pericardial fatty tissue. The tumor was diagnosed as a liposarcoma or teratocarcinoma based on imaging results; however, the possibility of lung cancer could not be excluded. Finally, EFN was diagnosed based on the postoperative histopathological examination. The patient underwent surgical resection of the suspected right extrapulmonary tumor. The intraoperative findings revealed a mediastinal mass contiguous with pericardial fat located between the middle and lower lobes. Intraoperative pathological examination of the lesion was performed using a needle biopsy; however, no definitive diagnosis was made. The tumor may have invaded the middle lobe of the right lung, and partial resection of the right lower lobe was performed in addition to resection of the middle lobe of the right lung. The patient was followed up every 3 months without adjuvant therapy. No recurrence was reported at 1 year after surgery. CONCLUSION EFN should be considered in the differential diagnosis of an extrapulmonary tumor when continuity with the pericardial space is observed on MRI or other imaging studies. Surgical resection is useful in the diagnosis and treatment of EFNs. Preoperative three-dimensional reconstructive imaging and MRI should be used to identify vascular structures and confirm the continuity of the lesion with the surrounding tissues to ensure safe and rapid tumor removal.

Abstract
Wilson-Mikity syndrome (WMS) is a rare condition characterized by various respiratory and pulmonary abnormalities in neonates and infants. However, the diagnosis is based on the findings of physiological tests, such as respiratory function tests. Reports describing the histopathological features of WMS are limited. The patient was a 22-year-old woman with a history of WMS. She had been on a ventilator for the first three months of life due to pulmonary hypertension after early delivery at 24 weeks of gestation and required oxygen therapy until three years of age. One month before presenting at our clinic, the patient experienced chest pain and respiratory distress, and a left spontaneous pneumothorax was diagnosed based on a chest X-ray examination. The pneumothorax improved after the insertion of a thoracic drain but recurred soon thereafter. A histopathological examination revealed emphysematous changes associated with WMS in the background lungs, consistent with brevity. No postoperative complications were observed. The thoracic drain was removed on the second day, and the patient was discharged on the eighth postoperative day. Postoperatively, the patient was started on inhaled medication and was carefully monitored every three months. The present case suggests that childhood interviews are very important for adult patients who develop pneumothorax and that early surgical treatment may be selected based on a detailed interview. Moreover, postoperative follow-up should be carefully performed in collaboration with respiratory medicine in patients with pneumothorax originating from chronic obstructive pulmonary diseases such as WMS.

Abstract
Primary chondrosarcoma of the ribs is relatively rare, and its basic treatment is surgical resection. In cases with positive resection margins, additional resection is considered, but its indications are unclear. However, reported cases with positive resection margins have been limited. We report a 71-year-old man whose medical checkup revealed an abnormal shadow in the chest. The findings from chest computed tomography, axial T2-weighted magnetic resonance imaging (MRI), and contrast-enhanced MRI led to a diagnosis of chondrosarcoma of the right fourth rib, and surgical resection was performed. The chest wall defect was reconstructed with a Marlex mesh. Postoperative histopathologic diagnosis was grade 2 chondrosarcoma. Gross resection margins, which were marginal, were negative, and the resection margin was grade 1. The patient was followed up without adjuvant therapy and did not undergo additional surgery. For chondrosarcomas with negative gross margins but a marginal margin, additional resection should be considered depending on the histologic grade of the margins. In cases with extensive resection of the chest wall, it is useful to reconstruct the chest wall while paying careful attention to infection control.

Abstract
BACKGROUND The addition of pertuzumab to trastuzumab in neoadjuvant chemotherapy (NAC) for anti-human epidermal receptor 2 (HER2) positive breast cancer has shown a significant improvement in the pathologic complete response (pCR) rate. However, the add-on effect of an anthracycline-based regimen (standard-of-care regimen) remains unclear. In this retrospective, observational study, participants received pertuzumab combination therapy as NAC for HER2-positive primary breast cancer. METHODS This study was conducted from January 1, 2020, to December 31, 2022. Patients who had not received at least three courses of pertuzumab owing to adverse events or those who had received preoperative radiotherapy were excluded. RESULTS The pCR rate was 35.3% (12/34 patients). The pCR group had a significantly higher percentage of histopathologic grade III (1/11 patients, p=0.030) and a significantly higher percentage of hormone receptor-negative patients (7/12 patients, p=0.015) than the non-pCR group. The non-pCR group had a significantly higher incidence of vascular invasion than the pCR group (7/22 patients, p=0.036). Menopausal status, stage, and ki-67 values were not significantly different between the two groups. CONCLUSIONS This study suggests an unlikely add-on effect of an anthracycline-based regimen for NAC in HER2-positive breast cancer. Moreover, our results support that the pCR rate is high in patients with hormone receptor-negative, HER2-positive breast cancer.

Abstract
Radiation-associated breast angiosarcomas are rare following breast-conserving surgery. These angiosarcomas are considered adverse events associated with radiation therapy and are characterized by a high risk of both local and distant recurrence, even after complete resection. Despite this, there is currently no established standard treatment for them. The patient was a 70-year-old woman who had breast-conserving surgery for right breast cancer 10 years before presentation. She was followed up for 10 years after receiving 50 Gy of residual breast irradiation and an aromatase inhibitor for 5 years. During follow-up, a painless purplish area with induration, measuring 10 cm by 5.4 cm, was noted on the right nipple. A skin biopsy confirmed hemangiosarcoma. Treatment included surgery with a 2.0 cm margin from the area, followed by skin excision and total mastectomy. A final diagnosis of radiation-associated breast angiosarcoma was made. Radiation-associated breast angiosarcoma is a rare disease with a poor prognosis that lacks standard treatment. An aggressive skin biopsy should be considered when skin findings such as purpura are seen after breast cancer radiotherapy, as in this case.

Abstract
INTRODUCTION To investigate the feasibility of early surgical treatment and perioperative steroid use in patients with interstitial lung disease (ILD) complicated by pneumothorax. METHODS We retrospectively examined data, including patient characteristics, laboratory findings, surgical treatment details, postoperative complications, and deaths, of nine patients with ILD complicated by secondary pneumothorax. The patients had been treated at our hospital during the past 10 years. RESULTS All nine patients were male (median age, 69.0 years). A total of nine patients had a histopathologic diagnosis of ILD after surgery. Of these, five were clinically diagnosed with ILD before surgery. Collagen disease was diagnosed in one case, drug-induced in one case, and idiopathic ILD (IILD) in three cases. All nine patients were diagnosed with postoperative ILD, including one case of collagen disease, one case of drug-induced, three cases of idiopathic pulmonary fibrosis (IPF)/cryptogenic fibrosing alveolitis, one case of nonspecific interstitial pneumonia (NSIP), and three cases of cryptogenic organizing pneumonia (COP). Regarding preoperative clinical characteristics, the performance status (PS) was 0 or 1 in all patients. Overall, three patients received oxygen (0-3 L/min), whereas steroids were administered to five patients. The mean drainage period was 23.5 days, and this was consistent with the time taken from pneumothorax occurrence to surgery. Video-assisted thoracic surgery (VATS) and thoracoscopic-assisted surgery were performed in seven and two patients, respectively. No postoperative recurrence or surgery-related deaths occurred. CONCLUSIONS Early surgery for secondary pneumothorax complicated by ILD may be a viable option for patients in good preoperative condition. For patients who are preoperatively treated with steroids, continued use of steroids should be carefully considered.

Abstract
BACKGROUND Synchronous multiple lung cancers are rare and refer to the simultaneous presence of two or more primary lung tumors, which present significant challenges in terms of diagnosis and treatment. CASE SUMMARY We report a case of multiple synchronous lung cancers with hilar lymph node metastasis of small cell carcinoma of unknown origin in a 73-year-old man. Transbronchial lung biopsy revealed squamous cell carcinoma. Although enlargement of lymph node 12u was detected, no distant metastases were observed. The patient was preoperatively diagnosed with T1cN0M0 and underwent thoracoscopic right upper lobectomy with nodal dissection (ND2a). Based on histopathological findings, the primary lesion was squamous cell carcinoma. A microinvasive adenocarcinoma was also observed on the cranial side of the primary lesion. Tumors were detected in two resected lymph nodes (#12u and #11s). Both tumors were pathologically diagnosed as small cell carcinomas. The primary lesion of the small cell carcinoma could not be identified even by whole-body imaging; however, chemotherapy was initiated for hilar lymph node metastasis of the small cell carcinoma of unknown origin. CONCLUSION Multiple synchronous lung cancers can be accompanied by hilar lymph node metastasis of small cell carcinomas of unknown origin.

Abstract
Background and Objectives: Granulomatous mastitis is a benign disease with a clinical presentation similar to that of breast cancer, and is most commonly observed in women of childbearing age. Although it has been suggested that autoimmune diseases are involved in its pathogenesis, no specific treatments have been established. The occurrence of this disease during pregnancy has rarely been reported. We presented the case of a 37-year-old woman who complained of left breast induration at 24 weeks' gestation. Materials and Methods: She was pregnant and manifested a dichorionic, diamniotic placenta. At 24 weeks of gestation, the patient experienced a sensation of hardness in her left breast. Mastitis was suspected, and she was treated with cephem antibiotics. Simultaneously, she was diagnosed with erythema nodosum in the extremities. As her symptoms did not improve, an incisional drainage was performed. Bacterial cultures were obtained at 31 weeks of gestation, and Corynebacterium kroppenstedtii was detected. Results: An elective cesarean section was performed at 37 weeks of gestation, and the baby was delivered safely. After delivery, a needle biopsy was performed, and the patient was diagnosed with granulomatous mastitis. She was completely cured with prednisolone after weaning. In this case, the patient's condition was maintained through incision and drainage, as well as antibiotic, anti-inflammatory, and analgesic drugs during pregnancy. This approach was chosen, taking into consideration the potential side effects of steroids. Conclusions: This case suggests that incisional drainage and antibiotic therapy, as well as steroids and surgery, may be considered in the treatment of granulomatous mastitis occurring during pregnancy. This may also be true for management during delivery. After delivery, breastfeeding and steroidal therapy proved to be effective in treating the condition.

Abstract
Gastric metastases from breast cancer are difficult to distinguish from primary gastric cancer. We report two cases of gastric metastasis of breast cancer with a review of the literature. In the first case, a 77-year-old woman was diagnosed with adenocarcinoma after upper gastrointestinal endoscopy, which revealed an erosive lesion in the gastric corpus. She was treated with an aromatase inhibitor and a CDK4/6 inhibitor, but five years later, she developed multiple bone metastases and gastric lesions, and she is currently receiving weekly paclitaxel (PTX) and bev. In the second case, a 63-year-old woman underwent total mastectomy and axillary lymphadenectomy [invasive lobular carcinoma (ILC)]. Eleven years after the surgery, the patient complained of pharyngeal tightness, and upper gastrointestinal endoscopy revealed a type 4 gastric tumor in the gastric body and posterior wall. In conclusion, when a patient with ILC or advanced breast cancer presents with gastric symptoms and anemia, it is important to examine and treat the patient based on the possibility of gastric metastasis.

Abstract
RATIONALE Preoperative differentiation between pulmonary fractionation and solitary fibrous tumors (SFTs) is challenging. Diaphragmatic primary tumors are relatively rare among SFTs, with limited reports of abnormal vascularity. PATIENT CONCERNS A 28-year-old male patient was referred to our department for surgical resection of a tumor near the right diaphragm, Thoracoabdominal contrast-enhanced computed tomography (CT) scan revealed a 10 × 8 cm mass lesion at the base of the right lung. The inflow artery to the mass was an anomalous vessel in which the left gastric artery bifurcated from the abdominal aorta, and its origin was the common trunk and right inferior transverse artery. DIAGNOSIS The tumor was diagnosed as right pulmonary fractionation disease based on the clinical findings. The postoperative pathological examination determined a diagnosis of SFT. INTERVENTIONS The pulmonary vein was used to irrigate the mass. The patient was diagnosed with pulmonary fractionation and underwent surgical resection. Intraoperative findings revealed a stalked, web-like venous hyperplasia anterior to the diaphragm, contiguous with the lesion. An inflow artery was found at the same site. The patient was subsequently treated using a double ligation technique. The mass was partially contiguous with S10 in the right lower lung and stalked. An outflow vein was identified at the same site, and the mass was removed using an automatic suture machine. OUTCOMES The patient received follow-up examinations that involved a chest CT scan every 6 months, and no tumor recurrence was reported during 1 year of postoperative follow-up. LESSONS Differentiating between SFT and pulmonary fractionation disease may be challenging during preoperative diagnosis; therefore, aggressive surgical resection should be considered as SFTs may be malignant. Identification of abnormal vessels using contrast-enhanced CT scans may be effective in reducing surgical time and improving the safety of the surgical procedure.

Abstract
Invasive mucinous adenocarcinoma often presents with pneumonia-like findings on imaging, which complicates its diagnosis. This case demonstrates that aggressive bronchoscopy is useful for examining infiltrating shadows in the lung field and large tumors occupying the entire lung lobe should be treated cautiously when lung parenchyma develops.

Abstract
A subareolar breast abscess (SBA) is caused by the formation of an inflammatory abscess around the milk duct. SBAs usually occur in females, and reports of SBAs in males are very rare. This study reports the case of a 62-year-old male patient who presented with a subcutaneous nodule and diffuse erythema around the left nipple. Ultrasonography revealed a mixed lesion measuring 2.5 x 1.5 cm, mostly cystic. A computed tomography scan of the chest showed an irregular, nodular structure in the same area. Magnetic resonance imaging with contrast enhancement suggested an abscess. A needle biopsy was performed on the lesion, and results showed moderate inflammatory cell infiltration, including lymphocytes, plasma cells, neutrophils, and abscess formation, thus leading to the diagnosis of SBA. The patient did not strongly desire a surgical procedure. He was treated with the cephem antibiotic cefaclor and antipyretic analgesics. During the six-month healing period, cefaclor was administered for a total of six weeks. Once he improved, recurrence was observed two years after the onset of the disease; however, the symptoms improved with conservative treatment, such as warm compresses. Preventive measures should be considered as SBAs are prone to recurrence.

Abstract
Granulomatous mastitis (GM) is a benign inflammatory breast disease that often poses diagnostic challenges due to its similar clinical and radiographic features to breast cancer. We report the case of a 34-year-old female with concurrent GM and ductal carcinoma in situ (DCIS). Initially, breast cancer was suspected based on imaging; however, a needle biopsy confirmed GM. Corticosteroid treatment led to a reduction in tumor size, but subsequent imaging continued to suggest the presence of breast cancer. Surgical excision ultimately revealed the coexistence of GM and DCIS. It is essential to consider the possibility of concurrent breast cancer in cases of GM with discordant imaging and pathology findings.

Abstract
Pneumothorax is a known complication of coronavirus disease 2019 (COVID-19). The concept of pneumothorax ex vacuo has also been proposed to describe pneumothorax that occurs after malignant pleural effusion drainage. Herein, we present the case of a 67-year-old woman who had abdominal distension for 2 months. A detailed examination led to the suspicion of an ovarian tumor and revealed an accumulation of pleural effusion and ascitic fluid. Thoracentesis was performed, raising the suspicion of metastasis of high-grade serous carcinoma arising from the ovary. An ovarian biopsy was scheduled to select subsequent pharmacotherapy, and a drain was inserted preoperatively into the left thoracic cavity. Thereafter, a polymerase chain reaction analysis revealed that the patient was positive for COVID-19. Thus, the surgery was postponed. After the thoracic cavity drain was removed, pneumothorax occurred, and mediastinal and subcutaneous emphysema was observed. Thoracic cavity drains were then placed again. The patient’s condition was conservatively relieved without surgery. This patient may have developed pneumothorax ex vacuo during the course of a COVID-19 infection. Since chronic inflammation in the thoracic cavity is involved in the onset of pneumothorax ex vacuo, careful consideration is required for the thoracic cavity drainage of malignant pleural effusion and other fluid retention.

Abstract
Multiple endocrine neoplasia (MEN) type 1 is a hereditary syndrome characterized by hyperplasia and adenoma of the parathyroid gland, pancreatic tumor, and pituitary tumor. We report a rare case of thymic neuroendocrine tumor diagnosed after removal of a thymic tumor following pancreatic and parathyroid surgery. A 35-year-old man was diagnosed with MEN type 1 by hypercalcemia and gastrinemia with a ureteral tone. Two well defined nodules in the anterior mediastinum on computed tomography (CT), and a high degree of accumulation on positron emission tomography (PET) was noted. Surgery was performed through a median sternotomy with anterior mediastinal tumor resection. Pathology showed thymic neuroendocrine tumor (NET). Immunostaining results were different from pancreatic NET and duodenal NET, and a diagnosis of primary thymic NET was made. Postoperative radiation therapy was completed as adjuvant therapy, and the patient is alive without reccurrence.

Abstract
Liposarcoma often occurs in the extremities and retroperitoneum. Primary mediastinal liposarcoma is uncommon, and there is no settled opinion regarding adjuvant therapy after surgery. We have recently experienced a relatively rare case of primary dedifferentiated liposarcoma of the posterior mediastinum. The patient was a 76-year-old woman. An abnormal shadow was noted in the posterior mediastinum. Esophageal submucosal tumor and gastrointestinal stromal tumor were suspected; endoscopic ultrasound-guided fine needle aspiration was performed, but a definitive diagnosis could not be obtained. As the tumor tended to slowly grow, surgical resection was performed. Based on histopathological findings, the patient was diagnosed with primary dedifferentiated liposarcoma of the posterior mediastinum. Owing to the presence of a positive surgical margin, postoperative radiotherapy (60 Gy/24 fr/6 w) was administered. No recurrence was observed after three and a half years of follow-up. The prognosis of primary dedifferentiated liposarcoma of the posterior mediastinum with a positive surgical margin is poor, but postoperative radiotherapy may be useful.

Abstract
Abstract
Background Eribulin is a chemotherapeutic drug that prolongs overall survival (OS) in patients with HER2-negative metastatic breast cancer (MBC), mainly in third-line or later chemotherapy (ChT) [1]. However, health-related quality of life (HRQOL) and efficacy in patients who receive eribulin as first- or second-line therapy is not well known. In contrast, S-1, an oral 5-fluorouracil derivative, shows similar OS to taxanes as first-line ChT and better HRQOL, based on a large phase III trial conducted in Japan [2]. Here, we compared the effect on HRQOL and efficacy of eribulin and S-1 in MBC patients in a first- or second-line ChT setting. Methods We planned an open-label, multicenter, randomized controlled phase III study at 50 hospitals in Japan. We enrolled patients with HER2-negative MBC who had no or one previous ChT for MBC regardless of prior administration of anthracyclines and taxanes. Patients were randomly assigned (1:1) to either eribulin (1.4 mg/m² administered on days 1 and 8 of a 21-day) or S-1 (40–60 mg twice daily for 14 consecutive days, followed by a 7-day break). Randomization was stratified by institution, age, treatment line, hormone receptor status, and time from surgery to recurrence. HRQOL assessment was conducted using the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 questions (QLQ-C30) every six weeks until week 24, and then every nine weeks until week 42 after baseline assessment. The primary outcome measure was the global health status (GHS) score of EORTC QLQ-C30, with a prespecified non-inferiority margin of 10% for a difference in the proportion of patients experiencing deterioration at one year. Clinically meaningful deterioration was defined as a ≥ 10-point decrease from baseline GHS score or death. Secondary outcomes were OS, progression-free survival (PFS), and adverse events. We estimated that the study needed 330 patients to obtain 80% power for non-inferiority. This trial was registered with the University Hospital Medical Information Network, Japan (protocol ID 000021398). Results Between June 2016 and October 2019, 302 patients were enrolled, with 152 assigned to eribulin and 148 to S-1. The full analysis set for HRQOL assessment included 134 and 136 patients, while that for efficacy consisted of 141 and 144 patients, respectively. Overall compliance with the questionnaire was 85.6 %. Among the full analysis set for efficacy, 28 (19.9%) and 31 (21.5%) cases were triple negative, respectively. Eribulin and S-1 were administered as first-line ChT in 99 (70.2%) and 101 (70.1%) patients, respectively. Risk difference of GHS deterioration through one year for the eribulin versus S1 group was -0.66% (95% CI -12.47 to 11.16; P non-inferiority =0.077). Median time to first deterioration in GHS score was 5.64 months (95% CI 3.51–8.00) and 5.28 months (95% CI 3.28-7.80) (HR 1.07 [95% CI 0.79–1.45]; P =0.667); median OS was 35.0 months (95% CI 27.2-41.0) and 27.8 months (95% CI 24.6-33.5) (HR 0.69 [95% CI 0.50-0.95]; P=0.023); and median PFS was 6.07 months (95% CI 5.48-7.80) and 6.66 months (95% CI 5.48-7.77), respectively (HR 0.90 [95% CI 0.68-1.18]; P=0.427). No previously unrecognized adverse events were observed. Conclusions We found a marginal non-inferiority in HRQOL for eribulin, albeit that the difference was not statistically significant owing to the smaller than planned sample size. Time to first clinically meaningful deterioration was almost identical between the two arms, whereas OS was significantly extended with eribulin. These findings indicate that eribulin in first- or second-line ChT is acceptable as a standard regimen in this patient population. [1] Lancet 2011; 377: 914–23 [2] Lancet Oncol 2016; 17: 90–98

Abstract
Abstract
Background: The Phase III POTENT trial demonstrated an improvement in invasive disease-free survival (IDFS) by the addition of S-1, an oral fluoropyrimidine, to adjuvant endocrine therapy in patients with ER-positive/HER2-negative early breast cancer. Because the trial was terminated at the interim analysis as the primary endpoint was met, the result of the overall survival (OS) remains immature. Methods: This multicenter observational study aimed to investigate the survival outcomes of patients who participated in the POTENT trial, in which patients with stage I to IIIB ER-positive, HER2-negative breast cancer without protocol-defined low-risk features received adjuvant endocrine therapy alone or with S-1 for 1 year. Of the full analysis set (FAS) of the POTENT trial (N=1930), patients who withdrew the consent or whose institutions terminated the contract were excluded from this study. The primary endpoint was OS. Secondary endpoints were IDFS and distant recurrence-free survival (DRFS). Results: A total of 337 patients (17%) in the POTENT study were excluded from this analysis (eight patients withdrew consent and 329 patients for institutions whose contract had been terminated). A total of 1593 patients were included in this study (803 in the endocrine therapy alone group and 790 in the endocrine therapy plus S-1 group). The median follow-up was 77.5 months (IQR: 68.8–86.0). The median duration of endocrine therapy was 71 and 69 months in the endocrine therapy alone and endocrine therapy plus S-1 groups, respectively. The patient characteristics were well balanced between the treatment groups, except for the number of lymph nodes involved. The endocrine therapy alone group included more patients with four or more positive nodes than the endocrine therapy plus S-1 group (12% vs. 9%, P=0.01). 58 (7%) patients in the endocrine therapy alone group and 51 (6%) in the endocrine therapy plus S-1 group died (HR 0.89, 95%CI: 0.61–1.30, P=0.54). The 5-year overall survival estimate was 94.7% (95%CI: 92.9–96.1%) in the endocrine therapy alone group and 95.6% (95%CI: 93.8–96.8%) in the endocrine therapy plus S-1 group. IDFS events were observed in 166 patients (21%) in the endocrine therapy alone group and in 135 patients (17%) in the endocrine therapy plus S-1 group (HR 0.80, 95%CI: 0.64–1.01). DRFS events occurred in 123 patients (15%) in the endocrine therapy alone group and in 91 patients (12%) in the endocrine therapy plus S-1 group (HR 0.74, 95%CI: 0.56–0.97). Conclusions: In this observational study, data from 337 patients (17%) were missing from the FAS of the POTENT trial. Both the endocrine therapy alone group and endocrine therapy plus S-1 groups showed favorable OS, and OS was similar between the treatment groups. The benefit of IDFS and DRFS by the addition of S-1 to endocrine therapy were maintained.

Abstract
Human telomerase reverse transcriptase (hTERT) is highly expressed in various cancers, including breast cancer. Although telomere elongation is an essential role for hTERT, the nuclear export after oxdative stress has also been shown in several cancer cell lines and is associated with drug-resistance in vitro. As only a few reports focused on the subcellular localization of hTERT in clinical specimens, we performed immunohistochemistry (IHC) and analyzed the correlation between intracellular hTERT expression and the clinicopathological characteristics to identify the clinical significance of hTERT subcellular expression in breast cancers. 144 invasive breast cancers classified by IHC subtype without primary systemic therapy (PST), were selected from a surgical resection cohort and were immunostained for hTERT, p-STAT3, p-AKT and p-ERK. The nuclear and/or cytoplasmic staining intensity and proportion of hTERT were scored and compared with clinicopathological parameters. The nuclear hTERT expression was significantly correlated with HER2 expression (p = 0.00156), and the scores were significantly correlated with p-STAT3 and p-AKT expression scores (r = 0.532, p = 0.000587 and r = 0.345, p = 0.0339, respectively) in the HER2-immunopositive breast cancer including luminal-HER2 and HER2 subtypes. Furthermore, hTERT was expressed more in cytoplasm in the specimens after PST than those before PST, and the score tended to be negatively correlated with tumor shrinkage rate in HER2 subtype (r = -0.593, p = 0.0705). These results suggest that nuclear and/or cytoplasmic hTERT may play a different role before and after PST including the tumorigenesis and drug-resistance in breast cancer. Suppression of cytoplasmic hTERT expression may lead to more effective strategy for drug-resistant HER2 subtype in breast cancer.

Abstract
Chemotherapy-induced peripheral neuropathy (CIPN) is an important clinical challenge that threatens patients' quality of life. This sub-study of the ABROAD trial investigated the influence of single nucleotide polymorphisms (SNPs) on CIPN, using genotype data from a randomized study to determine the optimal dose of a 3-week-cycle regimen of nab-paclitaxel (q3w nab-PTX) in patients with metastatic breast cancer (MBC). Patients with HER2-negative MBC were randomly assigned to three doses of q3w nab-PTX (SD: 260 mg/m2 vs. MD: 220 mg/m2 vs. LD: 180 mg/m2). Five SNPs (EPHA4-rs17348202, EPHA5-rs7349683, EPHA6-rs301927, LIMK2-rs5749248, and XKR4-rs4737264) were analyzed based on the results of a previous genome-wide association study. Per-allele SNP associations were assessed by a Cox regression to model the cumulative dose of nab-PTX up to the onset of severe or worsening sensory neuropathy. A total of 141 patients were enrolled in the parent study; 91(65%) were included in this sub-study. Worsening of CIPN was significantly greater in the cases with XKR4 AC compared to those with a homozygote AA (HR 1.86, 95%CI: 1.00001-3.46, p=0.049). There was no significant correlation of CIPN with any other SNP. A multivariate analysis showed that the cumulative dose of nab-PTX was most strongly correlated with CIPN (p<0.01).

Abstract
e12576 Background: From the results of ACOSOG Z0011, IBCSG23-01 and AMAROS trials, axilla surgery in node-positive breast cancer (BC) tends to be less invasive with sentinel node biopsy (SNB) followed by adjuvant therapy and regional node irradiation (RNI). However, optimized axilla treatment including SNB without RNI is still debated. The Japanese Society for Sentinel Node Navigation Surgery conducted a multi-institutional prospective cohort study to compare SNB with SNB followed by axillary lymph node dissection (ALND) in cases with positive-sentinel lymph nodes (SLN)(UMIN No. 000011782, Jpn J Clin Oncol, p.876-9, 2014). Methods: Female BC patients with cT1-3N0-1M0 were eligible. When 1 to 3 positive micrometastases or macrometastases in SLN were confirmed by histological or molecular diagnosis, SNB alone or additional ALND had been decided by physician’s discretion. Primary chemotherapy before or after SNB was acceptable for registration. Lymph node sampling was also allowed in the SNB group. Cases with bilateral BC, isolated tumor cells only in SLN, past history of invasive cancer within 5 years at the registration were ineligible. The primary endpoint was the 5-year recurrence rate of regional node (RN) in the SNB group. The secondary endpoint was overall survival (OS). We planned to collect 240 patients to reject that the 5-year recurrence rate of RN was more than 10% assuming the rate 5%. To compare the SNB group and ALND group, the propensity score matching (PSM) was performed. Matching variables were initial treatment, metastatic size and numbers of SLN, clinical stage, age, body mass index, menopausal status, family history, past history of invasive cancer, breast surgery. Results: Eight-hundred eighty cases had been registered between 2013 and 2016. In the 871 eligible cases, 308 cases were the SNB group. At the median follow-up of 6.3 years, 5-year recurrence rate of RN was 2.7% [95% confidence interval, 1.4% to 5.4%] and 5-year OS was 97.6% [94.9% to 98.8%]. After PSM, 209 cases were matched in the SNB and ALND group. Among them, 343 cases (82%) received operation at initial treatment. Partial and total mastectomy was performed in 225 (54%) and 193 cases (46%), respectively. One-positive SLN was recorded in 366 cases (88%), 2 in 48 (11%) and 3 in 4 (1%). Macrometastases and micrometastases in SLN were diagnosed in 271 (65%) and 147 cases (35%), respectively. Three-hundred seventy-six cases (90%) belonged to luminal-like subtype. RNI was underwent in 42 cases (20%) of the SNB group and 13 cases (6%) of the ALND group. Five-year recurrence rate of RN was 2.1% [0.8% to 5.5%] and 2.0% [0.8% to 5.3%] for the SNB and ALND group, respectively. Conclusions: Our series suggests that RNI is not necessary for regional control in cases with 1 to 3 positive SLN. In conclusion, SNB alone is acceptable in cases with fewer metastatic SLN. Clinical trial information: UMIN No. 000011782.

Abstract
Although neoantigens are one of the most favorable targets in cancer immunotherapy, it is less versatile and costly to apply neoantigen-derived cancer vaccines to patients due to individual variation. It is, therefore, important to find highly immunogenic antigens among tumor-specific or associated antigens, which are shared among patients. Considering the cancer immunoediting theory, immunogenic tumor cells cannot survive in early phase of tumor progression including two processes: elimination and equilibrium. We hypothesized that highly immunogenic molecules are allowed to be expressed in tumor cells after immune suppressive tumor microenvironment was established, if these molecules contribute to tumor survival. In the current study, we focused on TWIST1 as a candidate of highly immunogenic antigens because it is upregulated in tumor cells under hypoxia and promotes tumor metastasis, which are observed in late phase of tumor progression. We demonstrated that TWIST1 had an immunogenic peptide sequence TWIST1140-162 , which effectively activated TWIST1-specific CD4+ T-cells. In a short-term culture system, we detected more TWIST1-specific responses in breast cancer patients than in healthy donors. Vaccination with the TWIST1 peptide also showed efficient expansion of TWIST1-reactive HTLs in humanized mice. These findings indicate that TWIST1 is a highly immunogenic shared antigen and a favorable target for cancer immunotherapy.

Abstract
Activation of STING signaling plays an important role in anti-tumor immunity, and we previously reported the anti-tumor effects of STING through accumulation of M1-like macrophages in tumor tissue treated with a STING agonist. However, myeloid cells express SIRPα, an inhibitory receptor for phagocytosis, and its receptor, CD47, is overexpressed in various cancer types. Based on our findings that breast cancer patients with highly expressed CD47 have poor survival, we evaluated the therapeutic efficacy and underlying mechanisms of combination therapy with the STING ligand cGAMP and an antagonistic anti-CD47 mAb using E0771 mouse breast cancer cells. Anti-CD47 mAb monotherapy did not suppress tumor growth in our setting, whereas cGAMP and anti-CD47 mAb combination therapy inhibited tumor growth. The combination therapy enhanced phagocytosis of tumor cells and induced systemic anti-tumor immune responses, which rely on STING and type I IFN signaling. Taken together, our findings indicate that coadministration of cGAMP and an antagonistic anti-CD47 mAb may be promising for effective cancer immunotherapy.

Abstract
Background Anthracycline (A) or taxane T-based regimens are the standard early-line chemotherapy for metastatic breast cancer (BC). A previous study has shown a survival benefit of eribulin in heavily pretreated advanced/recurrent BC patients. The present study aimed to compare the benefit of eribulin with treatment of physician’s choice (TPC) as first- or second-line chemotherapy for recurrent HER2-negative BC.
Methods Patients with recurrent HER2-negative BC previously receiving anthracycline and taxane AT-based chemotherapy in the adjuvant or first-line setting were eligible for this open-label, randomized, parallel-group study. Patients were randomized 1:1 by the minimization method to receive either eribulin (1.4 mg/m2 on day one and eight of each 21-day cycle) or TPC (paclitaxel, docetaxel, nab-paclitaxel or vinorelbine) until disease progression or unacceptable toxicity. The primary endpoint was progression-free survival (PFS). Secondary endpoints included time to treatment failure (TTF), overall response rate (ORR), duration of response, and safety (UMIN000009886). Results Between May 2013 and January 2017, 58 patients were randomized, 57 of whom (26 eribulin and 31 TPC) were analyzed for efficacy. The median PFS was 6.6 months with eribulin versus 4.2 months with TPC (hazard ratio: 0.72 [95% confidence interval (CI), 0.40–1.30], p = 0.276). Median TTF was 6.0 months with eribulin versus 3.6 months with TPC (hazard ratio: 0.66 [95% CI, 0.39–1.14], p = 0.136). Other endpoints were also similar between groups. The most common grade ≥ 3 adverse event was neutropenia (22.2% with eribulin versus 16.1% with TPC). Conclusions Eribulin seemed to improve PFS or TTF compared with TPC without statistical significance. Further validation studies are needed.

Abstract
Triple-negative breast cancer (TNBC) has a poorer prognosis than other breast cancer subtypes; therefore, identifying markers of early recurrence is important. The present study aimed to establish a liquid biopsy protocol for droplet digital PCR-based detection of frequently mutated genes in patients with TNBC. Tumor DNA from 36 patients with TNBC who relapsed within 2 years after surgical resection was retrospectively analyzed. Somatic mutational profiles were evaluated using targeted sequencing to identify frequently mutated genes and genes associated with molecularly targeted therapies. The association between genetic alterations and associated protein phosphorylation was investigated using immunohistochemical analysis. Recurrent hot spot mutations in the plasma were monitored over time. Mutation-specific probes were used to successfully detect mutations in the blood samples of patients who were positive for PIK3CA H1047R and AKT1 E17K mutations. Somatic mutations in AKT1 (14.9%) and PIK3CA (25.5%) were frequently identified in the data. Robust phosphorylation of AKT and S6RP was more common in tumors with PIK3CA H1047R and AKT1 E17K mutational background than in tumors with wild-type PIK3CA and AKT1. In conclusion, the present study evaluated a high-sensitivity detection system for frequently mutated genes that was also applicable for cell-free DNA. The PI3K/AKT pathway was revealed to be activated in patients harboring PIK3CA H1047R and AKT1 E17K mutations; therefore, the PI3K/AKT pathway may be a promising candidate for targeted therapy in these patients.

Abstract
BACKGROUND Oral fluoropyrimidines, such as S-1, have been shown to have a role in controlling disease progression in metastatic breast cancer. We examined adjuvant treatment with S-1 in patients with oestrogen receptor (ER)-positive and HER2-negative primary breast cancer. METHODS We did a multicentre, open-label, randomised, controlled, phase 3 trial in 139 sites (137 hospitals and two clinics). Eligible patients were women aged 20-75 years with histologically diagnosed stage I to IIIB invasive breast cancer (intermediate to high risk of recurrence). Patients were temporarily registered at participating institutions and biopsy or surgical samples were collected and sent for central pathological assessment. Patients received 5 years of standard adjuvant endocrine therapy (selective oestrogen receptor modulators with or without ovarian suppression and aromatase inhibitors) with or without 1 year of S-1. Oral S-1 80-120 mg/day was administered twice a day for 14 days with 7 days off. Randomisation (1:1) using the minimisation method was done with six stratification factors (age, axillary lymph node metastasis at surgery or sentinel lymph node biopsy, preoperative or postoperative (neoadjuvant or adjuvant) chemotherapy, preoperative endocrine therapy, proportion of ER-positive cells, and study site). The primary endpoint was invasive disease-free survival, in the full analysis set (all randomly assigned patients, excluding those with significant protocol deviations). The safety analysis set consisted of all patients who received at least one dose of study treatment. Here, we report the results from the interim analysis at the data cutoff date Jan 31, 2019. This trial is registered with Japan Registry of Clinical Trials, jRCTs051180057, and the University hospital Medical Information Network, UMIN000003969. FINDINGS Between Feb 1, 2012, and Feb 1, 2016, 1930 patients were enrolled in the full analysis set, 957 (50%) received endocrine therapy plus S-1 and 973 (50%) received endocrine therapy alone. Median follow-up was 52·2 months (IQR 42·1-58·9). 155 (16%) patients in the endocrine therapy alone group and in 101 (11%) patients in the endocrine therapy plus S-1 group had invasive disease-free survival events (hazard ratio 0·63, 95% CI 0·49-0·81, p=0·0003). As the primary endpoint was met at interim analysis, the trial was terminated early. The most common grade 3 or worse adverse events were decreased neutrophil count (72 [8%] of 954 patients in the endocrine therapy plus S-1 group vs seven [1%] of 970 patients in the endocrine therapy alone group), diarrhoea (18 [2%] vs none), decreased white blood cells (15 [2%] vs two [<1%]), and fatigue (six [<1%] vs none). Serious adverse events were reported in nine (1%) of 970 patients in the endocrine therapy alone group and 25 (3%) of 954 patients in the endocrine therapy plus S-1 group. There was one (<1%) possible treatment-related death in the endocrine therapy plus S-1 group due to suspected pulmonary artery thrombosis. INTERPRETATION These data suggest that this combination of S-1 with endocrine therapy could be a potential treatment option for this intermediate and high-risk group of patients with ER-positive, HER2-negative primary breast cancer.

Abstract
Background Chemotherapy-induced peripheral neuropathy is commonly observed in patients treated with nanoparticle albumin–bound paclitaxel (nab-PTX). We conducted a multicenter randomized controlled study to evaluate the optimal dose of nab-PTX. Methods We compared three different doses of q3w nab-PTX (Standard: 260 mg/m2 [SD260] vs Medium: 220 mg/m2 [MD220] vs Low: 180 mg/m2 [LD180]) in patients with HER2-negative metastatic breast cancer (MBC). Primary endpoint was progression-free survival (PFS). Grade 3/4 neuropathy rates in the three doses were estimated using the logistic regression model. The optimal dose was selected in two steps. Initially, if the hazard ratio (HR) for PFS was <0.75 or >1.33, the inferior dose was excluded, and we proceeded with the non-inferior dose. Then, if the estimated incidence rate of grade 3/4 neurotoxicity exceeded 10%, that dose was also excluded. Results One hundred forty-one patients were randomly assigned to SD260 (n = 47), MD220 (n = 46), and LD180 (n = 48) groups, and their median PFS was 6.66, 7.34, and 6.82 months, respectively. The HRs were 0.73 (95% confidence interval [CI]: 0.42–1.28) in MD220 vs SD260, 0.77 (95% CI 0.47–1.28) in LD180 vs SD260, and 0.96 (95% CI 0.56–1.66) in LD180 vs MD220. SD260 was inferior to MD220 and was excluded. The estimated incidence rate of grade 3/4 neurotoxicity was 29.5% in SD260, 14.0% in MD220, and 5.9% in LD180. The final selected dose was LD180. Conclusions Intravenous administration of low-dose nab-PTX at 180 mg/m2 q3w may be the optimal therapy with meaningful efficacy and favorable toxicity in patients with MBC. Nab-Paclitaxel at 260 mg/m2 is used to treat metastatic breast cancer (MBC). Nab-Paclitaxel frequently causes severe neuropathy or myalgia. A reduced nab-paclitaxel dose of 180 mg/m2 q3w was effective and had less toxicities. Therapeutic indices of reduced doses were increased compared to the standard dose.

Abstract
Purpose To date, it is not clear which anticancer agent is useful in combination with trastuzumab and pertuzumab As the first and second selective regimens for advanced or metastatic breast cancer (AMBC), this multicenter, open-label, phase II trial (JBCRG-M03: UMIN000012232) presents a prespecified analysis of eribulin in combination with pertuzumab and trastuzumab. Methods We enrolled 50 patients with no or single prior chemotherapy for HER2-positive AMBC during November 2013–April 2016. All patients received adjuvant or first-line chemotherapy with trastuzumab and a taxane. The treatment comprised eribulin on days 1 and 8 of a 21-day cycle and trastuzumabplus pertuzumab once every 3 weeks, all administered intravenously. While the primary endpoint was the progression-free survival (PFS), secondary endpoints were the response rate and safety. Results Of 50 patients, 49 were eligible for safety analysis, and the full analysis set (FAS) included 46 patients. We treated 8 (16%) and 41 (84%) patients in first- and second-line settings, respectively. While 11 patients (23.9%) had advanced disease, 35 (76.1%) had metastatic disease. The median PFS was 9.2 months for all patients [95% confidence interval (CI): 7.0–11.4]. In the FAS, 44 patients had the measurable lesions and the complete response rate (CR) was 17.4%, and partial response rate (PR) was 43.5%. The grade 3/4 adverse events were neutropenia (5 patients, 10.2%), including febrile neutropenia (2 patients, 4.1%), hypertension (3 patients, 6.1%), and other (1 patient). The average of the left ventricular ejection fraction did not decline markedly. No symptomatic left ventricular systolic dysfunction was observed. Conclusions In patients with HER2-positive AMBC, eribulin, pertuzumab, and trastuzumab combination therapy exhibited substantial antitumor activity with an acceptable safety profile. Hence, we have started a randomized phase III study comparing eribulin and a taxane in combination with pertuzumab and trastuzumab for the treatment of HER2-positive AMBC.

Abstract
PURPOSE We developed a diagnostic method for pleural disseminated lesions of lung cancer using a combination of 5-aminolevulinic acid (5ALA) and autofluorescence observation system. We utilized a phenomenon in which externally ingested 5ALA is metabolized to protoporphyrin IX, a precursor of heme, which remains inside malignant cells and emits red fluorescence of approximately 630 nm. The diagnosis was made employing an observation system based on autofluorescence emitted from normal tissues that we have investigated. METHODS Between January 2017 and April 2019, we examined 82 lung cancer patients with suspected pleural invasion. We orally administered 5ALA (20 mg/m2) to the patients 4 hours before surgery, and malignant pleural lesions were thoracoscopically visualized using the autofluorescence observation system. RESULTS (1) Pleural disseminated lesions were observed in six patients. Of these lesions, two were not detected by usual white light inspection, and the use of this method enabled the diagnosis of disseminated lesions. (2) Regarding the diagnosis of lung cancer pleural invasion to estimate the risk of pleural dissemination, if limited to adenocarcinoma, the sensitivity was 93.9%; specificity, 74.3%; positive predictive value, 60.8%; and negative predictive value, 96.2%. CONCLUSION This method may facilitate the detection of minute disseminated lesions that are difficult to detect by usual inspection. In addition, the degree of pleural invasion may be diagnosed to evaluate the need for limited resection such as segmentectomy.

Abstract
Objective: Intraoperative evaluation of sentinel lymph nodes (SLNs) for patients with breast cancer is widely performed with frozen section (FS), cytology, or a combination of both. Touch imprint cytology (TIC) reportedly has an equivalent sensitivity to FS. We studied its diagnostic utility to detect SLN metastases. Materials and Methods: Cases of 367 patients with breast cancer who underwent intraoperative valuation of SLNs (507 LNs) were evaluated. All FS and corresponding TIC slides of SLNs of each case were reviewed microscopically for the presence of metastases of any size. If present, the metastatic focus was measured on the FS. Results: Of these 507 SLNs, 82 LNs (16.2%) from 69 women were found to have metastases in the FS and consisted of 5 LNs of isolated tumor cells, 15 of micrometastasis, and 62 of macrometastasis. TIC identified metastases in 69 of these 82 SLNs (sensitivity: 84.1%, specificity: 100%, and accuracy: 97.4%). All macrometastases could be detected by TIC, whereas TIC identified approximately 50% of micrometastases and none of isolated tumor cells. The size detection limit of metastatic foci, defined as the smallest dimension of metastasis detected without false negatives, was 2 mm. The smallest metastatic focus identified was 0.8 mm. Conclusions: TIC of SLNs is of great use given its negative predictive value of 100% for identification of macrometastasis in our study. For intraoperative evaluation of SLNs, based on our data, a practical two-step approach is proposed: SLN evaluation should be initially performed by TIC and then proceed to FS histological analysis only when cytologically positive to determine the size of metastatic focus.

Abstract
Background Trastuzumab (Tmab), pertuzumab (Pmab), and taxane has been a standard first-line treatment for recurrent or metastatic human epidermal growth factor (HER2)-positive breast cancer (HER2+ mBC) but has some safety issues due to taxane-induced toxicities. This has led to ongoing efforts to seek less toxic alternatives to taxanes that are equally effective when used in combination with Tmab plus Pmab. This study aims to show the non-inferiority of eribulin, a non-taxane microtubule inhibitor, against taxane, as a partner for dual HER2 blockade. Methods/design This multicenter, randomized, open-label, parallel-group, phase III study will involve a total of 480 Japanese women with HER2+ mBC who meet the following requirements: (1) age 20–70 years; (2) no prior cytotoxic chemotherapy (excluding trastuzumab-emtansine) for mBC; (3) ≥ 6 months after prior neoadjuvant or adjuvant cytotoxic chemotherapy; (4) presence of any radiologically evaluable lesion; (5) left ventricular ejection fraction ≥ 50%; (6) Eastern Cooperative Oncology Group performance status score of 0 or 1; (7) adequate organ function; and (8) life expectancy of at least 6 months. They will be randomized 1:1 to receive eribulin (1.4 mg/m2 on days 1 and 8) or taxane (docetaxel 75 mg/m2 on day 1 or paclitaxel 80 mg/m2 on days 1, 8, and 15) in combination with Tmab (8 mg/kg then 6 mg/kg) plus Pmab (840 mg then 420 mg) on day 1 of each 21-day cycle. The treatment will be continued until disease progression or unmanageable toxicity. The primary endpoint is progression-free survival as per investigator according to RECIST v1.1 criteria. Key secondary endpoints include objective response rate, overall survival, quality of life and safety. Non-inferiority will be tested with two margins of 1.33 and 1.25 in a stepwise manner. If non-inferiority is shown with a margin of 1.25, superiority will then be tested. Discussion If this study shows the non-inferiority, or even superiority, of Tmab, Pmab, and eribulin against the existing taxane-containing regimen, this new regimen may become a standard first- or second-line treatment option for HER2+ mBC in Japan. Trial registration ClinicalTrials.gov, ID: NCT03264547. Registered on 28 June 2017.

Abstract
Background A recent technical advance in mRNA in situ hybridization (mRNA-ISH) assays provides simultaneous signal amplification and background suppression with a unique probe design that enables single-molecule visualization. We assessed the utility of the mRNA-ISH assay as a diagnostic tool for detecting anaplastic lymphoma receptor tyrosine kinase (ALK) mRNA in non-small-cell lung carcinoma (NSCLC). We compared the mRNA-ISH assay with immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH). Methods The study included 279 surgically resected lung adenocarcinomas and 44 transbronchial-biopsied (TBB) adenocarcinomas. mRNA-ISH was conducted using the RNAscope 2.0 system, which includes pre-designed probes for detecting the tyrosine kinase domain encoded in ALK mRNA. IHC was conducted on all 323 samples using ALK-specific antibodies. mRNA-ISH was performed on 279 surgical samples and 6 TBB samples. Break-apart FISH was used to examine samples that were mRNA-ISH-positive or IHC-positive. Results ALK protein expression was detected in 11 of 279 specimens (3.9%). ALK mRNA was also detected with mRNA-ISH in ALK-positive samples, and 9 of the 11 specimens (81%) were also positive for ALK using break-apart FISH. Using the IHC results as a reference, the sensitivity and specificity of mRNA-ISH was 100%. In the TBB cohort, ALK protein expression was observed in 3 of 44 specimens (6.8%), in which ALK mRNA expression was also detected. Conclusions The ALK mRNA-ISH data were highly correlated with the IHC data, and ALK mRNA-ISH detected ALK mRNA expression in every FISH-positive sample. We conclude that mRNA-ISH could serve as an alternative or complementary method for diagnosing ALK rearrangements in NSCLC.

Abstract
Abstract
OBJECTIVE: Nab-paclitaxel (nab-PTX) has superior efficacy compared to conventional paclitaxel in metastatic breast cancer (MBC), but chemotherapy-induced peripheral neuropathy (CIPN) is more frequent with nab-PTX. In a single arm phase 2 trial (CA002-0LD), low dose nab-PTX (175 mg/m2) every 3 weeks (q3w) resulted in a good objective response rate (39.5%) without CIPN of grade 3 or higher. Therefore, we conducted a randomized controlled study to evaluate the optimal dose of nab-PTX by comparing a low dose (LD) and a medium dose (MD) to the standard dose (SD). Here, we evaluate the patients-reported outcomes (PROs) and health-related quality of life (HRQoL) in the ABROAD study.
PATIENTS AND METHODS: Three different doses of q3w nab-PTX (SD: 260 mg/m2 vs. MD: 220 mg/m2 vs. LD: 180 mg/m2) were administered in patients with HER2-negative metastatic breast cancer. The primary endpoint was progression-free survival (PFS). Grade 3/4 neuropathy rates with the three doses were estimated by logistic regression. The optimal dose was selected by 2-step selection. First, if the hazard ratio (HR) for PFS was <0.75 or >1.33, the inferior dose was dropped. Then, a dose with an estimated incidence of grade 3/4 neurotoxicity >10% was also dropped. PROs and HRQoL were assessed as secondary endpoints at baseline, and during the 2nd, 4th and 6th courses of protocol treatment using the Functional Assessment of Cancer Therapy-Taxane (FACT-Taxane), Patient Neurotoxicity Questionnaire (PNQ), Cancer Fatigue Scale (CFS) and EuroQol 5 Dimension (EQ-5D). The primary outcome for PROs and HRQoL was the FACT-Taxane trial outcome index (TOI), and inter-group comparison was performed using a mixed effect model for repeated measures (MMRM). This trial was registered with the University Hospital Medical Information Network (UMIN), Japan (protocol ID C000012429).
RESULTS: A total of 141 patients were randomly assigned to SD (n=47), MD (n=46) or LD (n=48) nab-PTX. PFS analysis showed that LD nab-PTX at 180 mg/m2/3 weeks was the optimal dose with good clinical efficacy and tolerability for patients with MBC (reported by Hara at ASCO2019). Longitudinal analysis (MMRM) showed that the difference from the baseline FACT-Taxane TOI score at MD and LD were significantly better than that at SD (MD vs. SD p<0.001, LD vs. SD p<0.001). Differences from baseline for the FACT-Taxane total score, physical well-being sub-score, and emotional well-being sub-score at MD and LD were also better than at SD. The difference from baseline for the CFS score at LD was better than that at SD (p=0.013) and those for EQ-5D utility scores at MD and LD were better than that at SD (MD vs. SD p=0.011, LD vs. SD p<0.001). There were no significant differences for the PNQ.
CONCLUSION: Our results show that low dose nab-PTX at 180 mg/m2/3 weeks could be an optimal dose for PFS and from the perspectives of PROs and HRQoL.

Abstract
Abstract
Background: The standard chemotherapy treatment strategy for patients with advanced/metastatic breast cancer (ABC) is the continuation of the same drug until tumor progression. However, despite continued antitumor effects, continuation of a drug often becomes difficult because of cumulative adverse events, such as peripheral neuropathy.
Methods: This multicenter, randomized, Phase II study in patients with estrogen receptorpositive (ER+) human epidermal growth factor receptor 2-negative (HER2−) ABC aimed to compare 2 treatment strategies following induction therapy with 4-6 cycles of the combined use of weekly paclitaxel (wPTX) and bevacizumab (BV). Patients in Arm A continued with wPTX+BV, whereas patients in Arm B were switched from wPTX to maintenance endocrine therapy (endocrine+BV) until disease progression, followed by wPTX+BV re-induction. The primary endpoint was time to failure of strategy (TFS), defined as the time from randomization to a qualifying event (addition of a new agent not in the primary regimen, progressive disease during or after planned therapy, or death). Secondary endpoints were overall survival (OS), progression-free survival, safety, and quality of life (QoL). Sequential plasma and serum biomarkers were analyzed for predicting/monitoring the response.
Result: Of 160 patients enrolled to receive induction therapy with wPTX+BV, 125 patients responded to treatment (complete response [CR], partial response [PR], or stable disease) and were randomized to either of the 2 treatment arms. Median follow-up was 21.3 months. Aromatase inhibitor (AI), fulvestrant, or AI with a luteinizing hormonereleasing hormone (LH-RH) analogue was used as maintenance endocrine therapy. The primary endpoint of TFS was 8.87 months (95% CI: 5.68-13.80) in the wPTX+BV continued group (Arm A) and 16.82 months (95% CI: 12.88-18.99) in the maintenance endocrine+BV group (Arm B) (hazard ratio [HR], 0.51; p<0.001). In Arm B, 52% of patients received wPTX+BV re-induction upon progression with maintenance therapy. Although the OS data were not yet mature, a trend of OS benefit was noted in a subset of patients in the maintenance group (Arm B) who achieved an objective response (CR or PR) to induction chemotherapy (HR, 0.75; 95% CI: 0.34-1.62). Health-related QoL data and biomarker analysis with IMPACT assay will be presented at the symposium.
Conclusion: This is the first study showing the benefit of maintenance endocrine therapy in patients with ER+ HER2− advanced breast cancer who responded to a fixed dose of chemotherapy. (UMIN: UMIN000012179; ClinicalTrials.gov: NCT01989780)

Abstract
Abstract
BACKGROUND: Although long-term prognostic outcomes of primary breast cancer (PBC) patients have been improved remarkably in recent years, the disease recurrence remains a serious problem. We have previously investigated a role for oral fluoropyrimidines in postoperative adjuvant treatments.In this study, we aimed to verify the usefulness of S-1 in combination with adjuvant endocrine therapy for PBC patients having luminal disease.
PATIENTS AND METHODS: This open-label, randomized, phase 3 trial was carried out in 139 centers in Japan. StageI-IIIPBC patients, who had hormone receptor (HR)-positive and human epidermal growth factor receptor 2 (HER2)-negativestatus and intermediate or higher risk of recurrence were randomly assigned (1:1) to receive standard endocrine therapy alone (control arm) or endocrine therapy plus S-1 (S-1 arm). Recurrence risk assessment was performed using anatomical stage, pathological findings such as histologic grade, and centrally confirmed proliferative marker status. S-1 was administered postoperatively in combination with standard endocrine therapy. For patients who underwent multi-drug postoperative adjuvant or preoperative neoadjuvant chemotherapy, S-1 was administered following the multi-drug chemotherapy. Cases having no residual cancer in the breast and axillary node after the preoperative chemotherapy were excluded from this study. The S-1 dosage was chosen among 80 mg/day, 100 mg/day, and 120 mg/day according to the body surface area of each patient, and S-1 was administered for one year with a 2 weeks on/1 week off administration schedule. The primary endpoint was invasive disease-free survival (iDFS), defined as time from randomization to invasive disease recurrence, occurrence of second invasive cancer event, or death, and was analyzed on an intent-to-treat basis. Secondary endpoints included DFS, distant DFS, overall survival, and safety profile.
RESULTS: From Feb 2012 to Feb 2016, 1959 patients were enrolled and 1932 patients were included in the full analysis set (control arm, 973; S-1 arm, 959). The results of the prespecified interim analysis met the primary end point, and this trial was terminated early. Median follow-up was 51.4 months. S-1 significantly reduced invasive events; 153 iDFS events were reported in the control arm and 99 iDFS events were reported in the S-1 arm [hazard ratio, 0.63 (95%CI, 0.49-0.81); p-value, 0.0003]. The 5-year iDFS estimate was 81.5% in the control arm and 86.9% in the S-1 arm. Distant recurrence as the first disease event was observed in 6.8% of patients in the S-1 arm and in 9.5% of those in the control arm. The safety data in patients treated with S-1 was consistent with the known profile of S-1. The S-1 treatment was well tolerated and manageable.
CONCLUSIONS: It was concluded that the postoperative adjuvant use of an oralfluoropyrimidine S-1 significantly reduced iDFS events and improved 5-year iDFS estimate in PBC patients having HR-positive and HER2-negative disease, in the combination with standard endocrine therapy, with a feasible safety profile.

Abstract
We experienced a surgical case of a rare primary tracheal tumor. A 77-year-old woman visited a local clinic with chief complaints of coughing, wheezing, and discomfort in the throat. Computed tomography revealed a mass measuring approximately 1.5 cm in the mediastinal trachea, extending from the membranous portion of the trachea to the esophagus. Bronchofibroscopy showed a flat, smooth-surfaced, round mass arising from the membranous portion. Surgery was performed because of the possibility of airway obstruction and suffocation. Sleeve resection of five tracheal rings was performed via median sternotomy and interrupted suture was performed using 3-0 absorbable suture material. The postoperative course was favorable and there has been no evidence of recurrence. The pathological diagnosis was solitary fibrous tumor. A primary solitary fibrous tumor of the trachea is extremely rare. Here, we report this disease with a literature review.

Abstract
1070 Background: Although nab-paclitaxel (nab-PTX) has shown superior efficacy compared to conventional paclitaxel in metastatic breast cancer (MBC), chemotherapy induced peripheral neuropathy (CIPN) was more frequently observed in nab-PTX. In a single arm Phase 2 trail (CA002-0LD), low dose nab-PTX (175mg/m2) every 3 weeks (q3w) demonstrated a good objective response rate (39.5%) without grade 3 or higher CIPN. Herein, we conducted multicenter randomized controlled study to evaluate optimal dose of nab-PTX comparing lower dose (LD or MD) to standard dose (SD). Methods: This study compared three different doses of q3w nab-PTX (SD: 260 mg/m2 vs. MD: 220 mg/m2 vs. LD: 180 mg/m2) in patients with HER2 negative metastatic breast cancer. Primary endpoint was progression-free survival (PFS). Grade 3/4 neuropathy rates in the three doses are estimated by the logistic regression. Optimal dose was selected by 2 step selection. At first, if hazard ratio (HR) for PFS was less than 0.75 or more than 1.33, the inferior dose was dropped. Then, if estimated incidence rate of grade 3/4 neurotoxicity exceed10%, that dose was also dropped. This trial is registered with the University Hospital Medical Information Network (UMIN), Japan (protocol ID C000012429). Results: In this study, 141 patients were randomly assigned to SD (n = 47), MD (n = 46) or LD (n = 48). Median PFS was 6.66 vs 7.34 vs 6.82 months, respectively. HR was 0.73 (95% confidence interval (CI): 0.42-1.28) in MD vs SD. SD was dropped due to inferiority to MD. HR was 0.77 (95%CI 0.47-1.28) in LD vs SD, and 0.96 (95%CI 0.56-1.66) in LD vs MD. LD and MD were carried over to next step due to equivalence. Overall survival was not different among all dose arms. Rate of dose reduction by treatment course was significantly higher in SD arm. Estimated incidence of grade 3/4 neurotoxicity rate was 29.5% in SD, 14.0% in MD and 5.9% in LD. Final selected dose was LD 180mg/m2. HR-QOL results will be presented. Conclusions: Low dose nab-PTX at 180 mg/m2/3 weeks could be an optimal dose with good clinical efficacy and tolerability for patients with MBC. Clinical trial information: C000012429.

Abstract
Abstract
Background: Docetaxel + Trastuzumab (H) + Pertuzumab (P) provided progression-free survival (PFS) and overall survival (OS) benefits in HER2-positive advanced or metastatic breast cancer (AMBC) in the CLEOPATRA study as a first-line therapy. However, long-term administration of docetaxel at a dose of 75 mg/m2 every 3 weeks in AMBC patients (pts) is difficult due to the toxicities. Eribulin mesylate (E) is a well-tolerated microtubule inhibitor, and we have reported the efficacy and safety of EHP regimen as first- and second-line therapy for AMBC in a multicenter, phase II study (JBCRG-M03/UMIN000012232). In this M06 study, we address the clinical question as to which is the better chemotherapy partner for HP as first line regimen, in terms of efficacy, toxicity and QOL.
Methods: JBCRG-M06 is a multicenter open-label randomized phase III study for HER2-positive AMBC pts who have received no prior chemotherapy except for the HER2- Antibody-Drug Conjugate (ADC). Pts will be randomized 1:1 to E (1.4mg/m2 on day 1 and 8) + H (8 mg/kg loading dose followed by 6 mg/kg) +P (840 mg loading dose followed by 420 mg) q3wks or standard taxanes (docetaxel 75mg/m2 on day1 or paclitaxel 80mg/m2 on day 1, 8 and 15) + HP q3wks. Stratification factors for randomization are; presence of visceral metastases, number of prior taxanes on perioperative adjuvant treatment, and treatment with prior anti-HER2-ADC. Primary endpoint is PFS and secondary endpoints include overall response rate, duration of response, OS, patient-reported outcomes (PRO) relating to QOL and peripheral neuropathy, new-metastases free survival, and safety. Translational research to search for biomarker for individual precision therapy will be performed. Main eligibility criteria are as follows: pts with HER2-positive AMBC, female aged 20-70 years old, ECOG PS of 0-1, LVEF ≥ 50% at baseline and adequate organ function. Pts who had progressive MBC within 6 months after the end of primary adjuvant systemic chemotherapy are excluded. The sample size was calculated by type1 error (2-sided) of 0.05 and 80% power to estimate the noninferiority margin 1.33 with an expected median PFS of 14.2 months. The target number of pts is 480 recruited over the duration of 3-years. The first patient in was achieved on August 2017. (ClinicalTrials.gov Identifier:NCT03264547).

Abstract
Background; NUT midline carcinoma (NMC) is a rare, highly aggressive tumor with t(15;19) translocation involving NUT midline carcinoma family member 1 (NUTM1) gene. NMC is genetically defined and diagnosed by RNA sequencing or by immunohistochemistry for NUT protein expression instead. However, it can be challenging to perform these assays on small biopsy specimens. We, here, report the utility of digital PCR (dPCR) assay for diagnosis of NMC. Methods; The QuantStudio 3D dPCR system (Thermo Fisher Scientific) was used. We designed optimal dPCR probes for the BRD4-NUT fusion gene and evaluated the dPCR method using NMC cell lines (HCC2429 and Ty82) and clinical samples. Total RNA was extracted from the cell lines and FFPE tissue samples from patients with thoracic tumors (RecoverAll total nucleic acid isolation kit, Thermo Fisher Scientific). cDNA was synthesized with SuperScript VILO cDNA kit (Thermo Fisher Scientific). PCR was performed using ProFlex PCR system (Thermo Fisher Scientific). Data was analyzed with QuantStudio 3D AnalysisSuite Cloud Software (Thermo Fisher Scientific). Results; We identified the BRD4-NUT fusion gene in HCC2429 and Ty82 cells using the dPCR system, which allowed us to detect the fusion gene at a prevalence < 0.1%. The fusion genes were detected in the clinical samples, and we successfully found NMC patients using the dPCR assay. Conclusion; We conclude the dPCR assay is an appropriate method for diagnosis of NMC.

Abstract
Abstract
[Background] Axilla surgery in node-positive breast cancer is dramatically changing from axillary lymph node dissection (ALND) to sentinel node biopsy (SNB). From the results of ACOSOG Z0011, IBCSG23-01 and AMAROS trials, adjuvant therapy and regional node irradiation could reduce regional lymph node recurrence for sentinel node-positive breast cancer patients. However, optimal indication of SNB alone remains uncertain. Trial design: To evaluate the outcome of sentinel node-positive breast cancer patients, the Japanese Society for Sentinel Node Navigation Surgery (SNNS) conducted a prospective cohort study in 2013 (UMIN000011782, Jpn J Clin Oncol, p.876-9, 2014). [Eligibility criteria] For eligible patients, SNB was performed or scheduled after 1 January 2012. Then 1 to 3 positive micrometastases or macrometastases in sentinel lymph nodes are confirmed by histological or molecular diagnosis. Primary chemotherapy before or after SNB is also acceptable for registration. [Specific aims] The primary endpoint is the 5-year recurrence rate of regional lymph node in patients treated with SNB alone. The secondary endpoint is the 5-year overall survival rate of this cohort. Patients treated with SNB followed by ALND are also registered simultaneously to compare the prognosis. The propensity score matching (PSM) is used to make the distributions of baseline risk factors comparable. [Statistical method] Based on an estimated recurrence rate of 5% at 5 years among patients treated with SNB alone, 240 patients are needed to give a 80% power to reject the null hypothesis that the recurrence rate is 10% with a one-sided type I error rate of 2.5%. If we consider that some patients will be lost to follow-up or become ineligible, a total of 250 patients will be needed to comprise the sample. [Present accrual] Eight hundred and eighty patients who underwent SNB alone or SNB followed by ALND were registered from 27 participating institutes between 2013 and 2016. Data cleaning is being performed. Patient's background and PSM will be reported.

Abstract
Abstract
Background: Pertuzumab provided overall and progression-free survival (PFS) benefits in HER2-positive metastatic breast cancer patients (pts) in the CLEOPATRA (Clinical evaluation of docetaxel, pertuzumab and trastuzumab) study. However, few studies have described the efficacy of other drugs in combination with pertuzumab plus trastuzumab. Here, we present a pre-specified analysis of eribulin in combination with pertuzumab plus trastuzumab as first- and second-line therapy for advanced or metastatic breast cancer (AMBC) in a multicenter, open-label phase II study (UMIN000012232, JBCRG-M03).
Methods: HER2-positive AMBC with no or single prior chemotherapy for AMBC were enrolled. All pts were administered trastuzumab and taxane as adjuvant or first-line chemotherapy. Treatment consisted of eribulin 1.4 mg/m2 on days 1 and 8 of a 21-day cycle and trastuzumab (8 mg/kg loading dose, then 6 mg/kg) plus pertuzumab (840 mg/body loading dose, then 420 mg/ body) once every 3 weeks, all administered intravenously. The primary endpoint was PFS, and secondary endpoints included overall response rate (ORR) and safety. PFS was determined using Kaplan–Meier analysis. Tumor response was assessed according to RECIST ver. 1.1.
Results: Fifty pts were enrolled from November 2013 to April 2016. Forty-nine pts were eligible for safety analysis and the full analysis set (FAS) included 46 pts. The median age was 56 years (23–70), and 8 (16%) and 41 (84%) pts were treated in first- and second-line settings, respectively. Eleven pts (23.9%) were de-novo Stage 4, and 35 pts (76.1%) had progressed in metastatic disease after completion of local therapy. Median PFS was 9.3 months (M) (95% confidence interval [CI]: 6.4–12.3). Table 1 shows the efficacy data for each treatment line and includes ORR, complete response rate (CR), partial response rate (PR), stable disease rate (SD), progressive disease rate (PD), not evaluable rate (NE) and PFS in the FAS. The median relative dose intensities of eribulin, trastuzumab, and pertuzumab were 93.3% (77.0%–100%), 100% (96.0%–100%), and 100% (89.7%–100%), respectively, in the FAS. The grade 3/4 adverse events (AE) were neutropenia in 5 pts (10.2%), including 2 pts (4.1%) with febrile neutropenia; hypertension in 3 pts (6.1%), and other AEs in only one patient. The average of the ejection fraction did not decrease significantly. Symptomatic left ventricular systolic dysfunction was not observed.
Conclusion: In pts with HER2-positive AMBC, first- and second-line therapy of eribulin in combination with pertuzumab plus trastuzumab demonstrated substantial antitumor activity with an acceptable safety profile. We are planning a phase III study comparing eribulin with taxanes in combination with pertuzumab plus trastuzumab for the treatment of HER2-positive AMBC.

Abstract
Inhalation burn injury (IBI) is a risk factor for mortality in burn patients. However, it is difficult to diagnose IBI using traditional physical examination alone, especially in prehospital settings. Therefore, facial burn patients are usually treated for suspected IBI. In the present study, we investigated whether fire site information could predict IBI as an alternative to traditional physical examination. This retrospective single-centre analysis involved 27 facial burn patients with suspected IBI who were admitted between 2014 and 2016. The patients were divided into two groups (IBI and non-IBI) according to bronchoscopy findings. Fire site information was compared between the two groups. The IBI (n = 13) and non-IBI (n = 14) groups were compared. Domestic fire was more frequent in the IBI group (69% vs. 29%, P = 0.035). The IBI group included one patient with carboxyhemoglobin ≥10% on admission. Prehospitalization fire site information, particularly domestic fires, might predict IBI in facial burn patients..
