Abstract
Background Hospital healthcare workers have been reported to have a high prevalence of musculoskeletal disorders, but their association with lateral epicondylitis (LE) is unknown. This study aimed to clarify the prevalence of LE and its associated factors among hospital healthcare workers. Methods The present study included all staff members of a secondary emergency hospital who provided their consent to participate. Participants with a history of elbow joint trauma were excluded from this study. The diagnostic criteria for definite LE were: (1) pain in the elbow joint within 2 weeks of the study; (2) pain in the lateral epicondyle region on resisted extension of the wrist with the elbow extended; and (3) tenderness in the lateral epicondyle. The diagnosis of LE was defined by meeting all criteria. Age, height, weight, sex, dominant hand, occupation, years of employment, smoking history, drinking history, personal computer usage history, and smartphone usage history were investigated using a questionnaire. A physical examination, in addition to evaluation of pain in the lateral epicondyle, grip strength and wrist extension strength were measured. A statistical analysis was used to assess the prevalence of LE and its associated factors. All investigations, including the diagnosis of LE, were performed by a single orthopedic specialist. Results We evaluated 544 individuals, corresponding to approximately 80% of all staff members. The median age was 39 years (interquartile range, 30-48). The study population included 154 males and 390 females. The occupations of the participants were as follows: nurses (n = 265), doctors (n = 47), clerks (n = 93), therapists (n = 27), certified care workers (n = 23), medical technologists (n = 22), pharmacists (n = 19), and others (n = 48). LE was diagnosed in 30 limbs/30 individuals with a prevalence of approximately 5.5%. There was no difference in the prevalence of LE among occupations (P = .85). A logistic regression analysis revealed that age (odds ratio, 1.05; 95% confidence interval 1.01-1.1; P = .01) and smoking history (odds ratio, 2.94; 95% confidence interval 1.01-8.56; P = .04) were independently associated with LE. Conclusion This study was conducted to evaluate the prevalence of LE among hospital healthcare workers. The prevalence of LE was 5.5%, and LE was independently associated with age and smoking history.

Impact of oral statin therapy on clinical outcomes in patients with cT1 breast cancer. BMC Cancer 2023; 23:224. [PMID: 36894884 PMCID: PMC9999569 DOI: 10.1186/s12885-023-10631-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Accepted: 02/09/2023] [Indexed: 03/11/2023] Open
Abstract
PURPOSE A previous meta-analysis examining the relationship between statin use and breast cancer reported that the inhibitory effect of statins on breast cancer may be more pronounced in early-stage cases. In this study, we aimed to investigate the effects of hyperlipidemia treatment at the time of breast cancer diagnosis and to examine its correlation with metastasis to axillary lymph nodes among patients with so-called cT1 breast cancer whose primary lesion was 2 cm or less and was pathologically evaluated by sentinel lymph node biopsy or axillary lymph node dissection. We also investigated the effects of hyperlipidemic drugs on the prognosis of patients with early-stage breast cancer. METHODS After excluding cases that did not meet the criteria, we analyzed data from 719 patients who were diagnosed with breast cancer, with a primary lesion of 2 cm or less identified by preoperative imaging, and who underwent surgery without preoperative chemotherapy. RESULTS Regarding hyperlipidemia drugs, no correlation was found between statin use and lymph node metastasis (p = 0.226), although a correlation was found between lipophilic statin use and lymph node metastasis (p = 0.042). Also, the disease-free survival periods were prolonged following treatment of hyperlipidemia (p = 0.047, hazard ratio: 0.399) and statin administration (p = 0.028, hazard ratio: 0.328). CONCLUSION In cT1 breast cancer, the results suggest that oral statin therapy may contribute to favorable outcomes.

Abstract
In patients undergoing mastectomy for locally advanced breast cancer, surgical skin flap reconstruction is sometimes required in order to cover large skin defects. Generally, we reconstruct by using latissimus dorsi or rectus abdominis when the direct closure is difficult. These constructions are difficult and have various complications. Our facility started rhomboid flap reconstruction after mastectomy. We report the result of rhomboid flap reconstruction. Five patients were performed rhomboid flap reconstruction. Three of 5 patients were cutaneous invasion, 1 patient was skin metastasis after mastectomy, and the other patient was Paget's disease. Regarding post operative complications, there were 2 cases of surgical site infection, 2 cases of skin necrosis and 1 case of seroma. The median length of postoperative hospital stay was 9 days. Median follow-up period was 381 days(221-508 days). Only 1 patient progressed. The median progression-free survival was 332 days(221-508 days). Rhomboid flap reconstruction is effective way for the improvement of the QOL of the patients with advanced breast cancer because the long term result was not bad and we can repair large skin defect easily.

Eribulin Treatment Promotes Re-expression of Estrogen Receptor in Endocrine Therapy-resistant Hormone Receptor-positive Breast Cancer Cells. Anticancer Res 2023; 43:603-611. [PMID: 36697070 DOI: 10.21873/anticanres.16196] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Revised: 12/14/2022] [Accepted: 12/15/2022] [Indexed: 01/26/2023]
Abstract
BACKGROUND/AIM Hypoxia is significantly associated with the development of drug resistance, and endocrine therapy is ineffective against hormone receptor (HR)-positive breast cancer in hypoxic tumor environments. Eribulin has a unique anticancer effect in breast cancer cells and improves tumor hypoxia by vascular remodeling. Therefore, we investigated the effect of eribulin on HR-positive breast cancer cells that were resistant to endocrine blockade. MATERIALS AND METHODS We established hypoxia-resistant breast cancer cell lines by continuous culture in a hypoxic environment. Parental and hypoxia-resistant cell lines were treated with eribulin and/or tamoxifen, and estrogen receptor (ER)-, epithelial-mesenchymal transition-, and hypoxia-related gene and protein expression changes in each surviving cell line were assessed. In addition, proliferation was assessed after eribulin treatment in the parental and hypoxia-resistant cell lines. We also assessed the effect of eribulin in vivo using subcutaneous xenograft models. RESULTS Hypoxia-resistant cell lines showed significantly decreased expression of epithelial and ER-related markers and exhibited a higher level of resistance to tamoxifen. Conversely, eribulin treatment increased epithelial and ER-related gene and protein expression in hypoxia-resistant cell lines and enhanced the anticancer effect of tamoxifen. In in vivo xenograft models, eribulin treatment of hypoxia- and tamoxifen-resistant tumors slightly induced the re-expression of ER. In addition, hypoxia-resistant tumors treated with eribulin tended to respond better to tamoxifen. CONCLUSION Eribulin ameliorated the aggressive behavior caused by hypoxia and induced the re-expression of ER in hypoxia-resistant breast cancer cells. Eribulin treatment of HR-positive breast cancer may resensitize cells to hormone blockade.

Prognostic Impact of Smoking on Bevacizumab Combination Chemotherapy for Advanced Breast Cancer. Anticancer Res 2023; 43:849-856. [PMID: 36697094 DOI: 10.21873/anticanres.16227] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Revised: 12/03/2022] [Accepted: 01/03/2023] [Indexed: 01/26/2023]
Abstract
BACKGROUND/AIM Smoking has been a proven carcinogenic risk factor for various cancers, including breast cancer. Furthermore, smoking has been recognized as a prognostic factor of breast cancer. Bevacizumab is a monoclonal antibody to vascular endothelial growth factor (VEGF) used in combination with chemotherapy to treat breast cancer. We, herein, investigated the effect of smoking on the prognosis of unresectable breast cancer patients who received bevacizumab plus weekly paclitaxel. PATIENTS AND METHODS From April 2011 to June 2022, 131 patients received bevacizumab plus weekly paclitaxel for unresectable breast cancer. At their first visit to our hospital, smoking status (i.e., period of smoking and amount of smoking per day) was evaluated by interview, and packs-years were calculated. RESULTS Time to treatment failure (TTF) was significantly longer in the high packs-years group than the low packs-years group (p=0.010, log-rank). The log-rank test showed that the high packs-years group had a significantly longer overall survival than the low packs-years group (p=0.049, log-rank). Multivariate analysis of TTF revealed that progesterone receptor (p=0.005, HR=0.408) and packs-years (p=0.007, HR=0.391) were independent factors. CONCLUSION A history of smoking may impact prognosis of combination chemotherapy with bevacizumab for advanced breast cancer treatment.

Clinical verification of the relationship between serum lipid metabolism and immune activity in breast cancer patients treated with neoadjuvant chemotherapy. Eur J Med Res 2023; 28:2. [PMID: 36593486 PMCID: PMC9806883 DOI: 10.1186/s40001-022-00964-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2022] [Accepted: 12/19/2022] [Indexed: 01/04/2023] Open
Abstract
BACKGROUND Lipid metabolism has been recently reported to affect the prognosis and tumor immune activity in cancer patients. However, the effect of lipid metabolism on chemosensitivity in patients with breast cancer treated with neoadjuvant chemotherapy (NAC) remains unclear. METHODS We examined 327 patients with breast cancer who were treated with NAC followed by curative surgery. The correlations between the serum levels of total cholesterol (TC) and triglyceride (TG) and the clinicopathological features, including the efficacy of NAC, neutrophil-to-lymphocyte ratio (NLR), and absolute lymphocyte count (ALC), were evaluated retrospectively. RESULTS Serum TG levels were increased after NAC in all the subtypes, and the rate of change was the highest, especially in triple-negative breast cancer (TNBC) (21.0% → 48.1%). In addition, only TNBC patients with an objective response (OR) had significantly higher TG levels after NAC than those without (P = 0.049). Patients with a high ALC before NAC had significantly higher TG levels after NAC than patients with all breast cancer (P = 0.001), HER2-enriched breast cancer (P = 0.021), and TNBC (P = 0.008). Patients with a low NLR before NAC had significantly higher TG levels after NAC only among patients with TNBC (P = 0.025). In patients with human epidermal growth factor receptor 2-enriched breast cancer, the group with normal TC levels before NAC had significantly better OS than those with high TC levels (P = 0.013, log-rank test), and in patients with TNBC, the group with high TC levels after NAC had significantly better OS than those with normal TC levels (P = 0.014, log-rank test). CONCLUSIONS Good systemic immune activity and chemosensitivity may be associated with lipid metabolism regulated by NAC in TNBC patients.

Abstract
BACKGROUND/AIM Febrile neutropenia (FN) is a potentially life-threatening complication of chemotherapy. In this study, we evaluated the predictors for FN according to neoadjuvant chemotherapy (NAC) in all breast cancer subtypes. PATIENTS AND METHODS We examined 327 patients with breast cancer treated with NAC. The correlation between the development of FN and clinicopathological features, including systemic inflammatory markers, and prognosis was evaluated retrospectively. RESULTS There were no significant differences between patients with and without FN in terms of disease-free survival or overall survival (p=0.562, p=0.149, log-rank, respectively). Low body mass index (BMI) (p<0.001), white blood cells (WBC) at baseline (p=0.008), and NAC regimen (p=0.026) significantly related with FN in all patients with breast cancer. Moreover, among patients with hormone receptor-positive/human epidermal growth factor receptor 2-positive breast cancer, low WBC (p=0.007) and low absolute lymphocyte counts (ALC) at baseline (p=0.039) were significantly associated with FN, and overall survival was significantly worse in patients with FN development (p=0.039, log-rank). CONCLUSION Poor immune activity-related factors, low ALC or BMI, may be useful to predict the development of FN in patients with breast cancer.

Abstract
BACKGROUND/AIM Intraoperative blood loss (IBL) during the surgical treatment of various cancers affects complication rates and prognosis. However, few studies have examined the importance of minimal IBL in breast cancer surgery. We used factor analysis to examine the prognostic importance of IBL in breast cancer. PATIENTS AND METHODS One hundred ninety-seven patients who underwent mastectomy plus axillary lymph node dissection (level II) after preoperative chemotherapy between June 2007 and June 2021 were included. Pearson's Chi-square test was used to confirm the relationships between different factors. Kaplan-Meier survival curves and the log-rank test were used to examine prognosis. Logistic regression was performed using a Cox proportional hazards model. RESULTS The median IBL was 55.0 g (range=5.0-420.0 g). IBL was <100 g in 143 patients (72.5%), 100-200 g in 39 patients (19.8%), and >200 g in 15 patients (7.6%). Logistic regression analysis showed that patients with IBL ≥200 g had a significantly worse prognosis (disease-free survival: p=0.003, log-rank test; overall survival: p<0.001, log-rank test). Factor analysis revealed that HER2-negative status (p=0.015), non-pathological complete response (p=0.031), obesity (p=0.001), heavy smoking (p=0.047), and diabetes mellitus (p=0.004) were significantly associated with increased IBL. CONCLUSION IBL in breast cancer was correlated with various clinicopathological factors associated with a poor prognosis, suggesting that increased IBL may be associated with poor prognosis in breast cancer as well.

Abstract
BACKGROUND/AIM Smoking worsens breast cancer prognosis. It has been reported that tobacco components directly reach the mammary gland tissue, causing smoking-related DNA damage and biological effects. We hypothesized that smoking may have characteristics that affect the therapeutic effect and clinical course in patients with stage IV hormone receptor-positive breast cancer (HRBC) who received endocrine therapy as the first-line treatment. PATIENTS AND METHODS Fifty-six patients diagnosed with stage IV HRBC were treated with endocrine therapy as the first-line treatment. Before treatment, the period and amount of smoking were confirmed through patient interviews, and each pack-year was recorded. RESULTS Disease progression with new metastases was more frequent in smokers than non-smokers during endocrine therapy as first-line treatment (p=0.034). Furthermore, as the pack-year increased, new metastases tended to appear [pack-year ≤15; hazard ratio (HR)=1.929, p=0.507; pack-year 15-30, HR=3.857, p=0.223; pack-year >30, HR=7.714, p=0.028]. CONCLUSION In stage IV HRBC, smoking increases the metastatic potential of breast cancer, suggesting that changes in its biology may lead to poor prognosis.

Abstract
BACKGROUND/AIM Tumor microenvironment (TME) assessment is considered to play an important role in the prediction of prognosis and therapeutic response following breast cancer treatment. No consensus has been reached regarding evaluation methods despite reports on the utilization of tumor-infiltrating lymphocytes (TILs) for immune TME (iTME) monitoring. Optimum timing of iTME assessment has not yet been established. PATIENTS AND METHODS Two hundred thirty-nine patients were treated with neoadjuvant chemotherapy (NAC). During the period from diagnostic needle biopsy to NAC initiation for breast cancer, the optimal evaluation timing was examined using a receiver operating characteristic (ROC) curve analysis. RESULTS A significant correlation between TILs and pathological complete response (pCR) was only observed in the short-term group (≤35 days) (p=0.033). Prognostic analysis revealed that in the short-term group, patients with high TIL levels had a significantly better survival prognosis relative to those with low TIL levels (>35 days) [disease-free survival (DFS): p=0.001, overall survival (OS): p=0.021]. TILs were identified as an independent factor affecting DFS in a multivariate analysis (p=0.008, hazard ratio=0.130). CONCLUSION TIL assessment during NAC for breast cancer is a prognostic predictor only when performed at ≤35 days before NAC initiation.

Abstract
BACKGROUND/AIM Augmented reality (AR) is a new technology that provides new awareness by using a computer to extend the real environment perceived by humans. Optical see-through head-mounted displays (OST-HMD) are worn on the head and can faithfully generate an AR image by wearing the device on the head as a spectacle-type device. We developed an ultrasound-guided needle biopsy technique using OST-HMD for breast tumors. PATIENTS AND METHODS Moverio BT-35E (Seiko Epson Corp, Nagano, Japan) was used as the OST-HMD device. This technique involves performing needle biopsy under direct vision via the gap at the bottom of the display while the ultrasound images are projected on the display of the OST-HMD worn on the head. RESULTS With this technique, needle biopsy can be executed smoothly with no posture restrictions. A flip shade affixed to the OST-HMD has 2% transmittance, which enables clearer projection of the images. CONCLUSION This article outlines the ultrasound-guided needle biopsy using OST-HMD. We established a safe and accurate biopsy technique with technological innovations using AR.

Abstract
Background Lymphocytes that surround cancer participate in tumor-related immune responses and are called tumor-infiltrating lymphocytes (TILs). Several recent reports suggest TILs index the tumor microenvironment and predict the therapeutic effect of chemotherapy. However, only few studies have studied the relationship between age and TILs. Aging reduces host immunity, and we predict that it may also affect TILs. Thus, we hypothesized that older breast cancer (BC) patients may have low TIL density than younger BC patients. Here, we retrospectively analyzed the differences in TILs by age and the therapeutic effects of preoperative chemotherapy (POC) in BC patients who were aged either less than 45 years or more than 60 years. Methods We retrospectively examined the data of 356 breast cancer patients who underwent POC, including 75 patients aged ≤ 45 years and 116 patients aged > 60 years. Using pre-treatment needle biopsy specimens, TIL density was compared for each age group by Student’s t-test. After analyzing different factors that affect TIL density, prognostic factors were also examined. Results Older patients with triple-negative BC had significantly lower TIL density than younger patients, while in human epidermal growth factor receptor 2 (HER2)-enriched BC, TIL density was significantly higher in the younger age group than that in the older age group. In addition, younger patients with HER2-rich breast cancer showed significantly higher complete pathological response rates than older patients with HER2-rich BC. In addition, significant differences in overall survival were observed among these patients with triple-negative BC. Conclusions Our study suggests that younger BC patients possess significantly higher TIL density than older patients. These differences may influence the therapeutic efficacy in highly immunogenic subtypes.

Abstract
Abstract
Background: The development of resistance to endocrine therapy appears to have become a major clinical problem of hormone receptor (HR) positive breast cancer. Drug resistance is associated with changes of the tumor microenvironment due to tumor hypoxia. Eribulin, a nontaxane, synthetic microtuble dynamics inhibitor, induces G2/M cell cycle arrest. Interestingly, it also has some unique anticancer effects in breast cancer cells, such as improvement of tumor perfusion and hypoxia. In this study, we investigated the effect of eribulin for endocrine therapy resistant breast cancer. Materials and Methods: We established hypoxia resistant HR positive/human epithelial growth receptor 2 (HER2) negative breast cancer cell lines, via continuous culturing in hypoxic environment. Parental and hypoxia resistant cell lines were treated with eribulin, followed by estrogen receptor (ER), epithelial-mesenchymal transition (EMT) and hypoxia related gene and protein expression changes in each surviving cells by quantitative real-time polymerase chain reaction (qPCR) and western blot, respectively. In addition, proliferation assay was conducted in these breast cancer cell lines treated with tamoxifen alone and tamoxifen plus eribulin. For the in vivo experiment, we produced subcutaneous xenografts of each cell lines. We treated these tumors with tamoxifen alone and tamoxifen plus eribulin, and analyzed their growth activity and protein expression by immunohistochemical study of surgically resected tissues. Results: Though parental HR positive/HER2 negative breast cancer cell lines displayed an epithelial-like cuboidal phenotype, hypoxia resistant cell lines displayed a mesenchymal-like spindle-shaped phenotype. In addition, hypoxia resistant cell lines significantly decreased the expression of epithelial and ER related markers, and exhibited a higher level of resistance to tamoxifen treatment. On the other hand, eribulin treatment for hypoxia resistant cell lines increased epithelial and ER related gene and protein expressions, and enhanced the anticancer effect of tamoxifen. In in vivo xenograft models, eribulin treatment for hypoxia resistant tumor with resistance to tamoxifen induced re-expression of ER. Also, hypoxia resistant tumor after administration of eribulin became effective with tamoxifen treatment. Conclusions: Eribulin improve the tumor microenvironment changed by hypoxia, and induce re-expression of ER in hypoxia resistant breast cancer cells. Eribulin treatment for HR positive breast cancer with resistance to endocrine therapy makes possibility of re-administration of endocrine therapy.

Clinical Significance of Expression of Immunoadjuvant Molecules (LAG-3, TIM-3, OX-40) in Neoadjuvant Chemotherapy for Breast Cancer. Anticancer Res 2022; 42:125-136. [PMID: 34969718 DOI: 10.21873/anticanres.15466] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2021] [Revised: 10/29/2021] [Accepted: 11/16/2021] [Indexed: 11/10/2022]
Abstract
BACKGROUND/AIM Various immunosuppressive factors that inhibit the immune response to cancer are present in cancer cells and the cancer microenvironment. Co-inhibitory and co-stimulatory receptors are dynamically expressed on T-cells as immunoadjuvant molecules that regulate the state of T-cell activity. In this report we focus on immunoadjuvant molecules such as LAG-3, TIM-3, and OX-40, for which there have been few published reports. We investigated the expression of LAG-3, TIM-3 and OX-40 in tumor-infiltrating lymphocytes (TILs), and clinically verified the significance of that expression in relation to neoadjuvant thermotherapy (NAC). PATIENTS AND METHODS A total of 177 patients with resectable early-stage breast cancer were treated with NAC. Estrogen receptor (ER), progesterone receptor (PgR), human epidermal growth factor receptor 2 (HER2), Ki67, LAG-3, TIM-3 and OX-40 status were assessed by immunohistochemistry. RESULTS The group with low-LAG-3 expression was significantly smaller than the group with high expression in triple-negative breast cancer (TNBC) (p=0.038) and HER2-enriched breast cancer (HER2BC) (p=0.021), while the total number of pathological complete response (pCR) patients was greater (p<0.001). In TNBC and HER2BC, the pCR rate was significantly higher in the low-LAG-3 expression group than in the high-LAG-3 expression group (p<0.001 and p=0.02, respectively). Moreover, on multivariate analysis low-LAG-3 expression status was an independent predictor of favorable prognosis (TNBC: p=0.014, HR=8.124; HER2BC: p=0.048, HR=10.400). CONCLUSION Our findings suggest that LAG-3 may become a biomarker in highly malignant breast cancers such as TNBC and HER2BC that can predict the therapeutic efficacy of NAC.

The Effect of Smoking on Progression from Ductal Carcinoma In Situ to Invasive Ductal Breast Carcinoma: A Retrospective Study. Anticancer Res 2022; 42:311-320. [PMID: 34969739 DOI: 10.21873/anticanres.15487] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2021] [Revised: 11/19/2021] [Accepted: 11/22/2021] [Indexed: 11/10/2022]
Abstract
BACKGROUND/AIM If ductal carcinoma in situ (DCIS) is diagnosed by needle biopsy, invasion is often found by removing the entire tumor and performing pathological examination. Smoking is a risk factor for carcinogenesis in breast cancer. We examined the correlation between the risk of invasion found by postoperative pathology and smoking history in patients diagnosed with DCIS by preoperative biopsy. PATIENTS AND METHODS We examined 128 patients who were diagnosed with DCIS by preoperative biopsy. Multivariate analysis was performed on the risk factors for invasion diagnosed by postoperative pathological examination in all cases diagnosed with DCIS by preoperative biopsy. RESULTS Multivariate analysis was performed on the risk factors for invasion diagnosed by postoperative pathological examination in all cases diagnosed with DCIS by preoperative biopsy. Number of pack-years was not an independent factor (p=0.349, OR=0.329), but current-smoker status (p=0.006, OR=not calculable) was an independent factor with VAB (p=0.018, OR=0.327). CONCLUSION Tobacco components may have an influence on the progression from DCIS to invasive ductal carcinoma.

Abstract
The patient was a 64-year-old woman. The patient was operated for left breast cancer(pT2N0M0, stage ⅡA, Luminal A). Eight years after surgery, CT findings revealed lung metastasis in the S8 and S9 areas of the left lung. The patient was treated with a combination of abemaciclib and letrozole, which resulted in a partial response(PR). One year after treatment, the lung metastases remained small, but multiple interstitial shadows appeared in both lower lung fields. The patient was diagnosed with drug-induced interstitial lung disease(Grade 1), and abemaciclib withdrawal and steroid therapy were initiated. After 3 months of treatment with prednisolone at 30 mg/day, the interstitial shadows tended to improve on CT, but a liver abscess was found in the S8 area of the right lobe of the liver. Prednisolone was tapered and abemaciclib was resumed at a dose of 200 mg/day, resulting in scarring of the lung injury and resolution of the liver abscess. The patient's PR was maintained for 18 months after relapse. We report a case of liver abscess during treatment of abemaciclib-induced interstitial lung disease.

Abstract
Primary adenoid cystic carcinoma(ACC)of the breast is a rare type of breast cancer. A 53-year-old woman with a right breast mass was examined at our institute. Ultrasonography showed 12.5×10.3×8.4 mm sized an ill-defined hypoechoic mass at zone C of the right breast. Pathological examination of core needle biopsy revealed atypical cells with solid and cribriform growth pattern. Computed tomography did not reveal lymph node metastases or distant metastases. The preoperative diagnosis was Stage ⅠA(cT1cN0M0, ER/PgR/HER2=-/-/1+)invasive ductal carcinoma or ACC. Surgery consisted of breast-conserving surgery and sentinel node biopsy. Pathological examination of the excised specimen revealed a so- called adenoid cystic pattern, so the final diagnosis was Stage ⅠA(pT1cN0M0, ER/PgR/HER2=-/-/1+)ACC. After 1 year of observation without adjuvant treatment, there has been no recurrence.

Abstract
A 78-year-old woman with a left breast cancer was examined at our institute. Ultrasonography showed 48 mm sized mass at zone C of the left breast, and left axillary lymph node swelling. Pathological examination of core needle biopsy revealed invasive ductal carcinoma and lymph node metastasis. In addition, contrast computed tomography showed 30 mm sized an hypovascular mass at pancreatic body involved the portal vein. Endoscopic ultrasound guided fine needle aspiration biopsy of the pancreas revealed adenocarcinoma. The diagnosis was synchronous double cancer including borderline resectable pancreatic body cancer and left breast cancer, and she received neoadjuvant chemotherapy consisting of gemcitabine and nab-paclitaxel. The effect of neoadjuvant chemotherapy was judged to be stable disease for breast cancer, partial response for pancreatic cancer. Then, she underwent pancreatosplenectomy with portal vein and gastroduodenal artery resection and reconstruction, left mastectomy and axillary lymph node dissection. Pathologic examination of the excised specimen revealed the diagnosis of breast cancer with osseous/cartilaginous differentiation and pancreatic moderately differentiated adenocarcinoma. She was treated with fluorouracil, epirubicin, and cyclophosphamide as adjuvant therapy, and there has been no recurrence.

Abstract
For qualitative diagnosis of breast mass, core needle biopsy(CNB)and fine-needle aspiration biopsy cytology(FNAC)are widely used. Overseas, vacuum-assisted biopsy(VAB)is often the first choice for qualitative diagnosis, and its proper use has become a clinical issue. In addition, with the progress of diagnostic imaging in recent years, the chances of finding micro-lesions such as ductal carcinoma in situ(DCIS)are increasing. Since a sufficient amount of tissue sample is required for these diagnoses and abundant biopsy materials are required, tissue biopsy by VAB may be desirable. The advantage of tissue biopsy with VAB is that accurate definitive diagnosis is possible by collecting a sufficient amount of tissue to obtain pretreatment tissue information. On the other hand, there is concern that patient stress may occur, such as hematoma formation after puncture and invasion by a thick puncture needle. It is lightweight and has an ergonomic design that provides stable grip. New technological innovations in this device may contribute to the reduction of patient stress, and are expected to be used in the future. We outline the experience of using BD EleVationTM in breast suction tissue biopsy at our institution.

Prediction of survival after eribulin chemotherapy for breast cancer by absolute lymphocyte counts and progression types. World J Surg Oncol 2021; 19:324. [PMID: 34775950 PMCID: PMC8591927 DOI: 10.1186/s12957-021-02441-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2021] [Accepted: 11/02/2021] [Indexed: 11/22/2022] Open
Abstract
Background In the Response Evaluation Criteria for Solid Tumors (RECIST) diagnostic criteria, the concepts of progression by preexisting disease (PPL) and progression by new metastases (PNM) have been proposed to distinguish between the progression types of cancer refractory to treatment. According to the tumor biology of cancer progression forms, the “PPL” form indicates invasion, and the “PNM” form indicates metastasis. On the other hand, recent studies have focused on the clinical importance of inflammatory markers as indicators of the systemic tumor immune response. In particular, absolute lymphocyte count (ALC) is an indicator of the host’s immune response. Thus, we developed a new measure that combined progression form with ALC. In this study, we clinically validated the combined assessment of progression form and ALC in eribulin chemotherapy. Methods From August 2011 to April 2019, a total of 486 patients with locally advanced or metastatic breast cancer (MBC) underwent treatment. In this study, only 88 patients who underwent chemotherapy using eribulin were included. The antitumor effect was evaluated based on the RECIST criteria, version 1.1. To measure ALC, peripheral blood samples collected before eribulin treatment were used. The cut-off value for ALC in this study was 1500/μl, based on previous studies. Results The PPL group (71 patients, 80.7%) had significantly longer progression-free survival (PFS) (p = 0.022, log-rank) and overall survival (OS) (p < 0.001, log-rank) than the PNM group (17 patients, 19.3%). In the 51 patients with ALC < 1500/μl, the PPL group had a significantly better prognosis than the PNM group (PFS: p = 0.035, OS: p < 0.001, log-rank, respectively). On the other hand, in the 37 patients with ALC ≥ 1500/μl, the PPL group had a better OS compared with the PNM group (p = 0.055, log-rank), but there was no significant difference in PFS between the two groups (p = 0.541, log-rank). Furthermore, multivariate analysis that validated the effect of OS showed that high ORR and “high-ALC and PPL” were factors for a good prognosis (p < 0.001, HR = 0.321; p = 0.036, HR = 0.290). Conclusions The progression form of PNM had a worse prognosis than PPL in patients treated with eribulin. In breast cancer patients with eribulin chemotherapy, good systemic immune status, such as ALC ≥ 1500/μl, was associated with less progression, particularly metastasis, and better prognosis. Furthermore, the biomarker “high-ALC (ALC ≥ 1500/μl) and PPL” was particularly useful as a prognostic marker following eribulin chemotherapy.

Abstract
Mammary Paget's disease is a rare malignancy. Mastectomy or breast-conserving surgery has been considered as the standard treatment, while there have been few reports of neoadjuvant chemotherapy (NAC). A 53-year-old woman with erythema and skin ulceration of the left breast was admitted to our institution. Breast examinations revealed left invasive ductal carcinoma (cT1bN0M0, cStage I), and a punch biopsy of the left mammary erythema indicated Paget's disease (cTisN0M0, cStage0). The patient received NAC because of multiple lesions. Consequently, the breast tumor clinically disappeared, and the erythema improved. These outcomes made it easier to perform surgery (left mastectomy and sentinel node biopsy). Histopathological examination revealed no residual cancer cells in either the mammary gland or breast skin, and no metastasis was found in the sentinel lymph node. Therefore, NAC may be a useful treatment for mammary Paget's disease.

Abstract
Purpose The body mass index (BMI) is commonly used as a simple indicator of obesity; patients with early-stage breast cancer who are obese (OB) per BMI measurements have been shown to have high postoperative recurrence and low survival rates. On the other hand, it has been shown that lymphocytes present in the vicinity of malignant growths that are involved in the tumors’ immune responses influence the efficacy chemotherapy. Therefore, we hypothesized that OB patients with breast cancer have a lower density of tumor-infiltrating lymphocytes (TILs), which may influence the therapeutic effect of preoperative chemotherapy (POC). In this study, we measured pretreatment BMI and TILs in patients with breast cancer who underwent POC, examined the correlations between these two factors, and retrospectively analyzed their therapeutic outcomes and prognoses. Methods The participants in this study were 421 patients with breast cancer who underwent surgical treatment after POC between February 2007 and January 2019. The patient’s height and weight were measured before POC to calculate the BMI (weight [kg] divided by the square of the height [m2]). According to the World Health Organization categorization, patients who weighed under 18.5 kg/m2 were classified as underweight (UW), those ≥18.5 kg/m2 and > 25 kg/m2 were considered normal weight (NW), those ≥25 kg/m2 and < 30 kg/m2 were overweight (OW), and those ≥30 kg/m2 were OB. The TILs were those lymphocytes that infiltrated the tumor stroma according to the definition of the International TILs Working Group 2014. Results The median BMI was 21.9 kg/m2 (range, 14.3–38.5 kg/m2); most patients (244; 64.5%) were NW. Among all 378 patients with breast cancer, the TIL density was significantly lower in OB than in NW and OW patients (vs. NW: p = 0.001; vs. OW: p = 0.003). Furthermore, when examining patients with each breast cancer type individually, the OS of those with TNBC who had low BMIs was significantly poorer than that of their high-BMI counterparts (log rank p = 0.031). Conclusions Our data did not support the hypothesis that obesity affects the tumor immune microenvironment; however, we showed that being UW does affect the tumor immune microenvironment.

Abstract
Objectives: This study was conducted to investigate the changes in clinical and psychosocial outcomes in patients with Dupuytren’s disease after initial treatment with collagenase Clostridium histolyticum (CCH) injection. Methods: This study involved 14 patients with Dupuytren’s disease who underwent treatment with CCH injection. The range of motion of each phalangeal joint was measured before treatment and at 6 months posttreatment. The following assessments were also carried out pre- and posttreatment: the Geriatric Depression Scale Short – Japanese version (GDS-J) to evaluate depressive status, Hand 10 to assess hand health status, and EuroQol-5-dimension-3-level Japanese version to evaluate health-related quality of life Results: Significant improvements were found in metacarpophalangeal joint extension and proximal interphalangeal joint extension. Significant differences were also found between values before the initiation of CCH injection and those at 6 months posttreatment for the EuroQol index score and the EuroQol Visual Analog Scale (VAS). Significant positive correlations were found between the pre- to posttreatment change in GDS-J scores and for the change in Hand 10 scores. Moreover, a significant negative correlation was found between the change in GDS-J scores and change in EuroQol index scores/EuroQol VAS scores before and at 6 months after CCH injection. Conclusions: For patients with Dupuytren’s disease, CCH therapy directly improved the health-related quality of life. The degree of improvement of depressive status was associated with the degree of improvement of hand health status and health-related quality of life.

Abstract
Angiosarcoma is a malignant mesenchymal tumor characterized by the presence of vascular endothelial cells. Although rare, angiosarcoma developing in the mammary glands has a poor prognosis. We report a case of breast angiosarcoma with a preoperative diagnosis of late recurrence of breast cancer. A 78-year-old woman noticed a tumor in her right breast and visited our hospital. The patient had undergone breast-conserving surgery and axillary lymph node dissection from the right breast 12 years before the visit. The tumor was diagnosed as T4bN0M0, stage IIIB. Anastrozole was administered as postoperative adjuvant therapy for 5 years; the patient also received 50-Gy whole-breast radiation therapy after surgery. Physical examination during her visit revealed an elevated lesion with blue purpura around the nipple in the right breast. We performed breast ultrasound and detected a well-defined 19.6 × 16.4 × 10.7 mm hypoechoic tumor in the left subareolar area. The patient underwent core needle biopsy (CNB). Based on the CNB specimen findings, she was suspected to experience late local recurrence after surgery. Therefore, she underwent total mastectomy after breast-conserving surgery. A dark-red tumor sized 18 × 12 mm was found in a specimen from the nipple. The pathological diagnosis of the specimen revealed short spindle-shaped tumor cells with strong nuclear pleomorphism and a significant interstitial fibrosis. Immunohistochemistry using D2-40 and CD31 antibodies showed irregular luminal proliferation at the anastomosis, infiltration into the surrounding tissue, and massive necrosis, thereby leading to the diagnosis of breast angiosarcoma. We have reported a case of breast angiosarcoma with a preoperative diagnosis of late recurrence of breast cancer.

Abstract
Background Iron is required for the proliferation of cancer cells, and its depletion suppresses tumor growth. Eribulin mesylate (eribulin), a non-taxane microtubule inhibitor, disrupts the tumor microenvironment via vascular remodeling and obstruction of the epithelial-mesenchymal transition (EMT). Herein, we investigated the effects of the iron chelator on tumor-related properties of breast cancer cells and the effects of iron chelator plus eribulin on tumor growth in vivo. Methods Two triple-negative breast cancer (TNBC) cell lines, MDA-MB-231 and BT-549, and one hormone-receptor positive breast cancer cell line, MCF-7, were used in our study. Cell proliferation, cell migration, cell cycle position, and gene expression were analyzed via MTT assays, wound-healing assays, flow cytometry, and quantitative real-time-polymerase chain reaction, respectively. For the in vivo experiments, mice with breast cancer xenografts were treated with the inhibitors, alone or together, and tumor volume was determined. Results Iron chelator inhibited breast cancer cell proliferation and decreased the proportion of S-phase cells. Conversely, it induced hypoxia, angiogenesis, EMT, and immune checkpoints, as determined by quantifying the expression of marker mRNAs in MDA-MB-231 and MCF-7 cells. Eribulin suppressed the expression of the hypoxia and EMT related marker mRNAs in the presence of iron chelator. Iron chelator plus eribulin inhibited tumor growth in vivo to a greater extent than did either inhibitor alone. Conclusions Although iron chelator induces oncogenic events (hypoxia, angiogenesis, EMT, and immune checkpoints), it may be an effective treatment for breast cancer when administered in combination with eribulin.

Abstract
The anti-PD-L1 antibody atezolizumab has become the standard of immunochemotherapy with the results of the international phase Ⅲ trials in lung cancer and breast cancer. We report a case in which atezolizumab was efficiency in PD-L1 (SP142)-positive lung and breast double cancer. A 56-years-old woman. She noticed a lump in her right breast and visited a nearby doctor, who referred her to our hospital for close examination and treatment. Ultrasonography revealed about 5 cm mass on the right mammary gland and axillary lymph nodes swelling. Core-needle biopsy was confirmed invasive ductal carcinoma( ER negative, PgR negative, HER2 negative, Ki-67 high expression). CT findings showed right mammary mass, right axillary lymph nodes swelling, liver mass, and lung tumor with mediastinal lymph nodes swelling. Therefore, a bronchoscopic biopsy was performed and a diagnosis of primary lung cancer was obtained. Pretreatment diagnosis was lung adenocarcinoma, cT2a, N2/3, M1b/1c(HEP, OSS), Stage ⅢA/B or ⅣA/B(PD-L1 positive), and right breast cancer, T4b, N2, M0/1 (HEP, OSS, LYM), Stage ⅢB or Ⅳ triple-negative(PD-L1 positive)double cancer. We underwent surgery(mastectomy with axillar lymph nodes dissection), followed by immunochemotherapy(atezolizumab, carboplatin, paclitaxel)and it was efficiency.

Abstract
BACKGROUND The peripheral blood neutrophil-lymphocyte ratio(NLR), platelet-lymphocyte ratio(PLR), and lymphocyte- monocyte ratio(LMR)of cancer patients have been proposed as indicators of systemic inflammatory response. Recombinant human-soluble thrombomodulin(rTM)has also been reported its efficacy in DIC associated with solid tumors. In this study, we investigated the clinical significance of inflammatory markers in rTM therapy for DIC associated with solid tumors. PATIENTS AND METHOD A retrospective study of 63 patients with solid tumors with DIC was performed. We examined the correlation between NLR, LMR, PLR and DIC withdrawal rate and 28-day survival rate. RESULTS The DIC withdrawal rate was not correlated in LMR(p=0.655), and significantly higher in low NLR and low PLR cases(p=0.037, p=0.024). Furthermore, 28-day survival rate was not correlated in LMR(p=0.632), and significantly higher in low NLR and low PLR cases(p= 0.046, p=0.014). CONCLUSIONS It was suggested that NLR and PLR may be useful as predictive markers of DIC withdrawal rate and 28-day survival rate in rTM therapy for DIC associated with solid tumors.

Abstract
Pertuzumab plus trastuzumab plus docetaxel regimen is the first choice for the initial treatment of HER2-positive recurrent breast cancer. However, docetaxel causes many adverse events. A 48-year-old woman was admitted to our hospital for a left breast tumor and was diagnosed with left breast cancer(T1N0M0, Stage Ⅰ, Luminal A). We performed a breast-conserving surgery and sentinel lymph node biopsy, followed by irradiation of the remaining parts of the mammary gland and adjuvant therapy with tamoxifen. Three and a half years after the first surgery, she underwent local resection due to chest wall recurrence of breast cancer. The recurrent tumor was HER2-positive, and we administered fluorouracil, epirubicin, cyclophosphamide( FEC)and paclitaxel plus trastuzumab. Liver metastases were confirmed on completion of cycle 11 of trastuzumab administration, and the regimen was changed to pertuzumab plus trastuzumab plus docetaxel. A partial response was seen following this regimen. The next line of treatment was the administration of 5 cycles of T-DM1, which resulted in stabilizing the disease. The liver metastases progressed, and the regimen was changed to pertuzumab plus trastuzumab plus eribulin. Partial response was seen following this regimen for liver metastases without serious adverse events(20 cycles).

Abstract
A 46-year-old man presented with right lower quadrant pain. Enhanced CT revealed a 30 mm sized irregular shaped mass originating from the appendix and invading the abdominal wall. We performed the laparoscopic appendectomy. Finally, the pathologic finding revealed a local advanced appendiceal carcinoma. From the intraoperative findings, the residual tumor was existed around the right external iliac vessels and abdominal wall. The patient was treated with chemotherapy for 13 months. Although the residual tumor encased the right external iliac vessels, the abdominal wall, and psoas major muscle, there were no signs of distant metastasis. We performed ileocecal resection with D3 lymph node dissection. The right external iliac vessels, abdominal wall, and psoas major muscle were resected simultaneously, and reconstructed by femoral- femoral bypass. As a result, R0 resection was achieved pathologically.

[PMID: 32934747 DOI: 10.3892/ol.2020.12041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2019] [Accepted: 04/01/2020] [Indexed: 12/24/2022] Open
Abstract
Currently, when determining treatment regimens, there is an emphasis on the quality of life (QOL), in addition to treatment efficacy. Especially in hormone receptor-positive breast cancer with distant metastases, unless death is imminent, a common first-line treatment is endocrine therapy, which has fewer side effects. In the present study, the differences in QOL were evaluated based on the age and prognostic indicators of 46 patients with hormone receptor-positive breast cancer with distant metastases (stage IV), who received first-line endocrine therapy at the Osaka City University Hospital (Osaka, Japan) between November 2007 and November 2016. QOL score before and after endocrine therapy was retrospectively analyzed, using the Quality of Life Questionnaire for Cancer Patients Treated with Anti-Cancer Drugs-Breast (QOL-ACD-B). There was no significant association between age and any of the clinicopathological features investigated. However, the QOL score of the elderly patient group was significantly higher compared with that of the younger group in the 'Satisfaction with treatment and coping with disease' subcategory (P=0.008). The QOL score of the younger age group in the same subcategory was significantly improved by the treatment (P=0.013). The patients that had an increased overall QOL score 3 months after treatment initiation had a significant extension of progression-free survival (PFS) rate compared to the patients with decreased or no change in QOL (P=0.032). In conclusion, psychological stress was more prominent in younger patients with stage IV breast cancer treated with hormonal therapy compared with elderly patients. Importantly, improving QOL within the 3 months after treatment initiation could lead to longer PFS rate.

Validation of Systemic and Local Tumour Immune Response to Eribulin Chemotherapy in the Treatment of Breast Cancer. Anticancer Res 2020; 40:3345-3354. [PMID: 32487630 DOI: 10.21873/anticanres.14317] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2020] [Revised: 05/07/2020] [Accepted: 05/08/2020] [Indexed: 11/10/2022]
Abstract
BACKGROUND/AIM In addition to its cytocidal effects as a microtubule dynamics inhibitor, eribulin mesylate (eribulin) regulates the tumour microenvironment. We examined the clinical significance of tumour infiltrating lymphocytes (TILs) and transforming growth factor-β (TGF-β), which are local markers of host immunity, and of the neutrophil-lymphocyte ratio (NLR) and absolute lymphocyte count (ALC), which are systemic markers. PATIENTS AND METHODS We administered eribulin chemotherapy to 106 patients with locally advanced or metastatic breast cancer. Of these, 21 had their lesions resected. RESULTS The response to eribulin was significantly associated with ALC (p=0.007). The expression of pSmad2 (an indicator of activation of TGF-β downstream signaling) was significantly decreased before and after eribulin chemotherapy (p<0.001). Moreover, a baseline ALC ≥ 1,500 /μl was observed in a significantly high number of patients with pSmad2 negative conversion (p<0.001). CONCLUSION Eribulin improved the tumour immune microenvironment by decreasing TGF-β expression. This demonstrated that local change can be evaluated based on ALC.

Effects of low-dose remifentanil infusion on analgesic or antiemetic requirement during brain function mapping: A retrospective cohort study. Acta Anaesthesiol Scand 2020; 64:735-741. [PMID: 31997302 DOI: 10.1111/aas.13554] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2019] [Revised: 01/03/2020] [Accepted: 01/16/2020] [Indexed: 12/30/2022]
Abstract
BACKGROUND Pain and discomfort during the awake phase in awake craniotomy should be relieved to facilitate brain mapping. Although some anaesthesiologists use low-dose (0.01-0.05 µg/kg/min) remifentanil infusion to provide analgesia during this phase, its efficacy and side effects have never been evaluated. Therefore, this study primarily aimed to investigate the effects of low-dose remifentanil infusion on the need for antiemetic treatment during brain mapping and secondarily aimed to determine its effects on the need for additional analgesic treatment. METHODS This retrospective study included 218 patients who underwent awake craniotomy at our centre from 2008 to 2018. The relationship between low-dose remifentanil infusion during the awake phase and the requirement for analgesic or antiemetic treatment was examined. A multivariable competing risk regression analysis was performed to adjust for patient and operative variables. RESULTS Sixty-six patients (30.3%) received low-dose (median rate: 0.01 µg/kg/min) remifentanil infusion during the awake phase. Forty-nine patients (22.5%) received an antiemetic and 99 (45.4%) received additional analgesic treatment. The difference in additional analgesic treatment was not significant between patients who received low-dose remifentanil infusion and those who did not (adjusted hazard ratio: 1.13; 95% confidence interval: 0.75-1.70; P = .570); however, the use of antiemetics significantly increased in patients who received remifentanil (adjusted hazard ratio: 1.78; 95% confidence interval: 1.01-3.15; P = .047). CONCLUSION Low-dose remifentanil infusion during the awake phase in awake craniotomy significantly increased the need for antiemetics but did not decrease the need for additional analgesic treatment.

Prediction of lymph node metastasis by tumor-infiltrating lymphocytes in T1 breast cancer. BMC Cancer 2020; 20:598. [PMID: 32590956 PMCID: PMC7318528 DOI: 10.1186/s12885-020-07101-y] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2020] [Accepted: 06/22/2020] [Indexed: 11/22/2022] Open
Abstract
Background Lymph node metastasis is more likely in early-stage breast cancer with lower tumor-infiltrating lymphocyte (TIL) density. Therefore, we investigated the correlation between TILs and lymph node metastasis in cT1 breast cancer patients undergoing surgery and the usefulness of TILs in predicting sentinel lymph node metastasis (SLNM) in cT1N0M0 breast cancer. Methods We investigated 332 breast cancer patients who underwent surgery as the first-line treatment after preoperative diagnosis of cT1. A positive diagnosis of SLNM as an indication for axillary clearance was defined as macrometastasis in the sentinel lymph node (SLN) (macrometastasis: tumor diameter > 2 mm). Semi-quantitative evaluation of lymphocytes infiltrating the peritumoral stroma as TILs in primary tumor biopsy specimens prior to treatment was conducted. Results For SLN biopsy (SLNB), a median of 2 (range, 1–8) SLNs were pathologically evaluated. Sixty cases (19.4%) of SLNM (macrometastasis: 46, micrometastasis: 16) were observed. Metastasis was significantly greater in breast cancers with tumor diameter > 10 mm than in those with diameter ≤ 10 mm (p = 0.016). Metastasis was significantly associated with lymphatic invasion (p < 0.001). These two clinicopathological factors correlated with SLNM even in patients diagnosed with cN0 (tumor size; p = 0.017, lymphatic invasion; p = 0.002). Multivariate analysis for SLNM predictors revealed lymphatic invasion (p = 0.008, odds ratio [OR] = 2.522) and TILs (p < 0.001, OR = 0.137) as independent factors. Conclusions Our results suggest a correlation between lymph node metastasis and tumor immune-microenvironment in cT1 breast cancer. TIL density may be a predictor of SLNM in breast cancer without lymph node metastasis on preoperative imaging.

Factors predictive of invasive ductal carcinoma in cases preoperatively diagnosed as ductal carcinoma in situ. BMC Cancer 2020; 20:513. [PMID: 32493410 PMCID: PMC7268513 DOI: 10.1186/s12885-020-07001-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2019] [Accepted: 05/25/2020] [Indexed: 12/24/2022] Open
Abstract
Background Invasion is often found during postoperative pathological examination of cases diagnosed as ductal carcinoma in situ (DCIS) by histological examinations such as core needle biopsy (CNB) or vacuum-assisted biopsy (VAB). A meta-analysis reported that 25.9% of invasive ductal carcinoma (IDC) cases are preoperatively diagnosed by CNB as DCIS. Risk factors for invasion have been studied by postoperative examination, but no factors have been found that could be obtained preoperatively from blood tests. In this study, we investigated factors predictive of invasion based on preoperative blood tests in patients diagnosed with DCIS by preoperative biopsy. Methods In this study, 118 patients who were diagnosed with DCIS by preoperative biopsy were included. Biopsies were performed with 16-gauge CNB or VAB. Peripheral blood was obtained at the time of diagnosis. This study evaluated absolute platelet count, absolute lymphocyte count, lactate dehydrogenase, carcinoembryonic antigen, and cancer antigen 15–3 (CA15–3). The platelet–lymphocyte ratio (PLR) was calculated by dividing the absolute platelet count by the absolute lymphocyte count, and patients were grouped into high PLR (≥160.0) and low PLR (< 160.0) groups. Results Invasion was found more frequently after surgery in pathologically high-grade cases than in pathologically not-high-grade cases (p = 0.015). The median PLR was 138.9 and 48 patients (40.7%) were classified into the high PLR group. The high PLR group was significantly more likely to have invasion detected by the postoperative pathology than the low PLR group (p = 0.018). In multivariate analysis of factors predictive of invasion in postoperative pathology, a high PLR (p = 0.006, odds ratio [OR] = 3.526) and biopsy method (VAB vs. CNB, p = 0.001, OR = 0.201) was an independent risk factor. Conclusions The PLR may be a predictor of invasion in the postoperative pathology for patients diagnosed with DCIS by preoperative biopsy.

Abstract
BACKGROUND/AIM The host's systemic inflammatory response is thought to affect the progression of cancer and the antitumor effects of chemotherapy. Meta-analyses have reported that the peripheral blood platelet-to-lymphocyte ratio (PLR) is a prognostic indicator of this effect. Therefore, we hypothesized that PLR may differ, depending on sentinel lymph node metastasis (SLNM) in patients diagnosed with cT1N0M0 breast cancer by preoperative imaging. This study investigated the ability of preoperative PLR to predict SLNM in patients diagnosed with cT1N0M0 breast cancer. PATIENTS AND METHODS This study included 475 patients with cT1N0M0 breast cancer diagnosed by preoperative imaging. Peripheral blood was obtained at diagnosis, i.e., before surgery. PLR was calculated from preoperative blood tests, by dividing the absolute platelet count by the absolute lymphocyte count. RESULTS The probability of SLNM was significantly higher (p=0.002) in cases where the tumor diameter was larger than 10 mm. The incidence of SLNM was significantly high in the high (preoperative) PLR group (p=0.031). Multivariate analysis revealed that high PLR [compared to low PLR, p=0.021, odds ratio (OR)=1.815, 95% confidence interval (CI)=1.093-3.090] and large tumor size (compared to small tumor size, p=0.001, OR=2.688, 95%CI=1.524-4.997) were independent factors influencing SLNM. CONCLUSION PLR may act as a predictor of SLNM in cT1N0M0 breast cancer.

The effect of smoking on biological change of recurrent breast cancer. J Transl Med 2020; 18:153. [PMID: 32248830 PMCID: PMC7132886 DOI: 10.1186/s12967-020-02307-x] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2020] [Accepted: 03/16/2020] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND The selection of treatment for a patient with breast cancer largely relies on the cancer subtype. However, this process is complicated by changes in tumor biology at relapse. Smoking has been identified as a risk factor for breast cancer. The direct effect of a tobacco component delivered via blood circulation on the mammary gland tissue and subsequent DNA damage have been proposed to explain the association between cigarette smoking and breast cancer carcinogenesis. This postulation is supported by both tissue culture and animal studies demonstrating that the associated DNA damage further alters breast cancer cells, as indicated by an increased proliferative capacity and malignant transformation. In this study, we aimed to explore the relationship between changes in Estrogen receptor (ER), progesterone receptor (PgR), and human epidermal growth factor receptor 2 (HER2) each receptor at recurrence, and smoking and the prognosis after recurrence. METHODS This retrospective study included 989 patients with primary breast cancer who developed relapse after surgery and 50 patients who underwent regenerative biopsy or surgery from December 2007 to March 2018. ER, PgR, and HER2 expression in the primary and recurrent lesions was evaluated using immunohistochemistry, and the correlations of these expression patterns with smoking history (pack-years) were examined. RESULTS When ER was evaluated in recurrent tumors, negative and positive conversions were recognized in 3 (6.0%) and 1 patient (2.0%), respectively. When PgR was evaluated, negative conversion was recognized in 15 patients (30.0%). When HER2 was evaluated, positive conversion was recognized in 6 patients (12.0%). Consequently, we observed a change in the intrinsic subtype in in 5 patients with recurrent tumors (10.0%). Although most clinical factors were not correlated with smoking, a positive conversion of HER2 in recurrence was significantly more frequent among smokers than among non-smokers (p = 0.024). CONCLUSIONS Biological changes during breast cancer recurrence should be given careful clinical consideration because they affect treatment after recurrence. Our results suggest that smoking may induce increased HER2 expression in recurrent breast tumors.

Abstract
CASE A 76-year-old man was referred to our hospital for advanced hepatocellular carcinoma(HCC)with chronic hepatitis type B. Although he underwent right anterior sectionectomy and S3 segmentectomy, multiple recurrences were found in the hepatic remnant after 2 months. Transcatheter arterial chemoembolization(TACE)and transcatheter arterial infusion (TAI)were performed separately. One and a half month after the last TAI, AFP and PIVKA-Ⅱ levels markedly elevated, and multiple early enhancing nodules with portal vein tumor thrombosis were detected on CT. A half dose of sorafenib(400mg/ day)was administered to the patient who was refractory to TACE. Sorafenib was discontinued after 4 weeks because the patient developed general fatigue and anorexia(Grade 3). Furthermore, these adverse events became worse, and ascites appeared. He was hospitalized in the palliative care unit for best supportive care for 3 weeks and also received outpatient treatment for more than 14 months. Fifteen months after discontinuing sorafenib administration, his condition improved dramatically, and CT revealed that the multiple HCC had reduced in size. Moreover, the portal vein tumor thrombosis disappeared. As his performance status and liver function were well preserved, he underwent partial hepatectomy for residual HCC. The patient remains alive without recurrence at 18 months, despite no administration of sorafenib. CONCLUSION This case demonstrates that sorafenib administration combined with surgical treatment could possibly cure advanced HCC refractory to TACE.

Abstract
In the treatment of advanced breast cancer, onlya few drugs confer overall survival(OS)benefit. Eribulin is a drug that was shown to extend OS in an international phase Ⅲtrial; however, the underlying mechanism is thought to involve cancer microenvironment regulation. The concept of "breast cancer subtype discordance" implies the biological changes that accompany treatment. Herein, we encountered a case of advanced breast cancer in a 54-year-old woman that showed biological changes after eribulin chemotherapy. The patient noticed a lump in her left breast and visited a nearby doctor, who referred her to our hospital for close examination and treatment. Ultrasonographyrevealed a large mass at the center of the left mammarygland and axillaryly mph node swelling. Core-needle biopsyconfirmed an invasive ductal carcinoma(ER stronglypositive, PgRnegative, HER-2 negative, Ki-67 low expression). CT findings showed multiple lung metastases. Letrozole was administered for cT4N2M1, stage Ⅳ, Luminal A, which showed progression to the left side with advances in breast cancer. Six months later, the primarytumor and axillaryly mph nodes showed progression. Subsequent treatment with eribulin was started, and partial response was obtained; however, new lymph node metastasis developed in the axilla after 11 cycles. The primary tumor and axillaryly mph nodes showed stronglypositive ER expression, were PgR-negative and HER2-positive, and showed Ki-67 low expression and HER2-positive conversion.

Abstract
BACKGROUND/AIM The utility of peripheral blood neutrophil-to-lymphocyte ratios (NLRs) and platelet-to-lymphocyte ratios (PLRs) as prognostic predictors of surgery and chemotherapy in breast cancer has been reported. In this study, NLRs and PLRs were calculated before treatment and during cancer progression in primary hormone receptor-positive breast cancer (HRBC) patients who chose endocrine therapy (ET) as the primary treatment, and prognostic prediction and factor analysis were performed. PATIENTS AND METHODS A total of 55 patients diagnosed with stage IIIB, IIIC, or IV HRBC who received ET as the primary treatment were included. RESULTS Increased NLRs were found to significantly contribute to a shorter overall survival from cancer progression (OS-CP) (p=0.040, log-rank). Increased PLRs were similarly associated with a shorter OS-CP (p=0.036, log-rank). In multivariate analysis, an increased NLR was an independent prognostic factor (p=0.035, hazard ratio(HR)=5.221). CONCLUSION Changes in NLRs and PLRs become prognostic indicators when the therapeutic effect of ET is limited.

Abstract
BACKGROUND/AIM Eribulin is currently used to treat advanced and metastatic breast cancer in the clinical setting; however, its efficacy is inhibited by resistance acquisition in many cases. Thus, the present study established two eribulin-resistant breast-cancer cell lines, and used these to investigate the mechanisms that underly eribulin-resistance acquisition. MATERIALS AND METHODS Eribulin-resistant breast-cancer cell lines were generated by culturing MDA-MB-231 and MCF-7 cells with increasing concentrations of eribulin. RESULTS The eribulin-resistant cells acquired resistance to eribulin, as well as several other anticancer drugs. After eribulin treatment, the eribulin-resistant cell lines showed no morphological change, no increased expression of epithelial-cadherin, nor any significant alteration in cell-cycle distribution. In contrast, the expression levels of programmed death-ligand 1 were increased in the MCF-7/eribulin-resistant compared to MCF-7 cells. CONCLUSION The herein developed eribulin-resistant cell lines acquired cross-resistance to various anticancer agents, and displayed resistance to eribulin-induced effects on microtubule function and epithelial-mesenchymal transition (EMT).

Abstract
BACKGROUND A higher density of tumor-infiltrating lymphocytes (TILs) can lead to greater therapeutic effects and improved prognoses in cancer treatment. Similar results have been observed in breast cancer, particularly in triple-negative breast cancer (TNBC) and human epidermal growth factor receptor 2-enriched breast cancer. Calcium channel blockers (CCBs) are antihypertensive drugs (AHTs) that have also been reported to suppress the functions of T cells and macrophages. In this study, we evaluated TILs before pre-operative chemotherapy (POC) in breast cancer and retrospectively analyzed the correlation between CCBs and TILs or prognosis. METHODS Of the patients treated with POC, 338 who had evaluable TILs were enrolled in this study. The correlations among TILs were evaluated according to standard methods, and CCB use and prognosis were investigated retrospectively. RESULTS Before POC, 65 patients (19.2%) took AHTs (CCBs: 41/338, 12.1%). The TIL density was significantly lower among patients administered CCBs for the group of all patients and for patients with TNBC (p = 0.040, p = 0.009, respectively). Additionally, patients with TNBC who were administered CCBs showed significantly lower response rates for POC (p = 0.040). In all patients receiving POC, no significant differences in disease-free survival (DFS) or overall survival (OS) were observed in patients administered CCBs (p = 0.712, p = 0.478, log-rank tests, respectively). Furthermore, no significant differences were found, even in patients with TNBC (DFS: p = 0.441, OS: p = 0.727, log-rank tests, respectively). CONCLUSIONS In patients with TNBC undergoing treatment for hypertension with CCBs, TILs in the needle biopsy specimens before treatment were significantly lower, and the response rate of POC was not sufficient. Thus, the immunosuppressive effects of CCBs may also affect the immune microenvironment.

Abstract
BACKGROUND Several studies have established a positive relationship between quality of life (QOL) and prognosis in patients with various cancer types. This study investigated QOL of elderly patients with primary hormone receptor-positive breast cancer who chose endocrine therapy as their first-line treatment. PATIENTS AND METHODS QOL-ACD-B scores were evaluated before and after endocrine therapy for 75 patients. The results of the interviews were used to determine the Charlson Comorbidity Index. RESULTS In a univariate analysis, baseline objective response rate (p=0.009), and increase in QOL (p=0.037) significantly correlated with longer progression-free survival time. There was a correlation between 3-month QOL score and longer overall survival in the multivariate analysis (p=0.035). CONCLUSION In elderly patients with breast cancer who underwent first-line endocrine therapy, improved QOL at 3 months after treatment initiation correlated with prolonged progression-free survival. High QOL scores were associated with prolonged overall survival.

Clinical verification of the relationship between smoking and the immune microenvironment of breast cancer. J Transl Med 2019; 17:13.

Abstract
Background The immune tumor microenvironment (iTME) is thought to affect the response to chemotherapy, and tumor-infiltrating lymphocytes (TILs) are often used as an indicator to evaluate the iTME. Smoking is involved in carcinogenesis, the relationship between smoking and the iTME of lung cancer has been reported. We hypothesized that smoking would affect the iTME of breast cancer and aimed to examine this relationship based on the amount of pre-diagnosis smoking and the subsequent effects on treatment response and prognosis. Methods This retrospective study evaluated data from 149 patients who underwent preoperative chemotherapy for triple-negative or HER2-enriched breast cancer. TILs were assessed in biopsy specimens at diagnosis. The data of all patients were used to calculate each patient’s smoking amount based on pack-years. Results Relative to the low smoking group, the high smoking group had a significant greater TILs density (p = 0.043) and a significantly better pathological complete response (pCR) rate (p = 0.042). However, there was no significant difference according to smoking amount in disease-free survival (p = 0.114) or overall survival (p = 0.347). Conclusions Smoking may influence the iTME, with an activated iTME being associated with pCR rate. Therefore, controlled activation of the microenvironment in this setting may help improve patients’ prognosis.

Abstract
Paget's disease of the breast is usually localized in the nipple epidermis and lactiferous duct located near the nipple. Here, we report a rare case of synchronous breast carcinoma with Paget's disease and invasive ductal carcinoma. A 50-year-old woman was admitted to our hospital because of abnormalities in screening mammography findings. Ultrasonography(US) findings showed a 2.4×1.3×1.6 cm sized hypoechoic lesion in a region of the left mammary gland. Computed tomography (CT)findings did not reveal distant metastasis. Magnetic resonance imaging(MRI)revealed an approximately 2.2 cm sized irregular tumor. The pretreatment diagnosis was left non-invasive ductal carcinoma(cTisN0M0, Stage 0), and surgery was performed. The tumor was found in the range of 40.2×15.0 mm, many of which were breast ductal growth. An infiltrated image was confirmed at multiple sites, but the maximum size was 2.5×1.5 mm. Pathological findings of the main lesion revealed papillotubular carcinoma. Agglomeration of heterotypic cells with abundant cytoplasm was observed in the epidermis of the papilla. The final diagnosis was invasive breast cancer(pT1aN3M0, Stage Ⅲc, Luminal HER2)coexisting with Paget's disease.

Abstract
A 73-year-old woman visited our hospital with the chief complaint of a mass in the left breast. Breast ultrasonography revealed a hypoechoic area in the left breast. A core needle biopsy showed the proliferation of solid tumor cells. Immunohistochemistry indicated strongly positive expression of E-cadherin, synaptophysin, and chromogranin A. We then diagnosed her with breast neuroendocrine carcinoma. The expression of estrogen receptor(ER)and progesterone receptor(PgR)were also strongly positive, and the expression of human epidermal growth factor receptor 2(HER2)was negative. Computed tomography( CT)and bone scintigraphy revealed no metastasis. Simple mastectomy of the left breast and sentinel lymph node biopsy were performed. Final pathological examination of the tumor also led to the diagnosis of breast neuroendocrine carcinoma(T2N0M0, StageⅡA, Luminal A-like). After surgery, endocrine therapy is planned, considering the breast cancer subtype. Breast neuroendocrine carcinoma is rare. It is important to consider the possibility of metastasis from other organs to the breast.

[A Case of a Malignant Phyllodes Tumor That Was Difficult to Distinguish from Stromal Sarcoma]. Gan To Kagaku Ryoho 2018; 45:2429-2431.

Abstract
A 72-year-old woman visited our hospital with the chief complaint of a mass in the right breast. Breast ultrasonography revealed a hypoechoic area with a distinct border in the right breast. A core needle biopsy showed the proliferation of spindle cells in the stroma, and she was diagnosed with stromal sarcoma or malignant phyllodes tumor. Right lumpectomy was performed. Pathological examination revealed a malignant phyllodes tumor with a sarcomatous lesion. Although she did not receive adjuvant chemotherapy, she is alive without any recurrence 2 years after the surgery. It is difficult to distinguish phyllodes tumors from stromal sarcoma, based on core needle biopsy, and the prognosis of malignant phyllodes tumors with distant metastases is poor. Rapid surgery to determine an accurate diagnosis and careful follow-up after surgery are impor- tant.

Abstract
A 40-year-old woman underwent right partial mastectomy and axillary lymph node dissection. Pathological examination confirmed right breast cancer(T2N0M0, Stage ⅡA, mucinous, ly3, v0, weakly positive ER and PgR). After surgery, she received radiotherapy for residual mammary gland cancer and endocrine therapy as adjuvant treatment for 5 years. Seven years after the first surgery, computed tomography showed multiple lung tumors. Transbronchial lung biopsy revealed lung metastasis from breast cancer(strongly positive ER and PgR, negative HER2). She received first-line endocrine therapy, and the response was classified as stable disease(SD). Three years later, the disease control became poor. Second-line endocrine therapy was then administered, and the response was classified as partial response(PR)for 3 years. After that, we modified the regimen to monotherapy of letrozole, and she achieved PR for a further 3 years. In the treatment for patients with metastatic hormone receptor-positive breast cancer, it is important to consider the sensitivity of endocrine therapy, such as relapse-free survival or the expression of hormone receptors in metastatic tumors.
