ABSTRACT
BACKGROUND: Electronic patient-reported outcomes monitoring (ePROM) is a useful communication tool for patients and healthcare providers in cancer chemotherapy. In this study, we examined the feasibility of our newly developed ePROM system, which we refer to as "Hibilog". METHODS: An ePROM app was developed by extracting 18 items from the Patient-Reported Outcome-Common Terminology Criteria for Adverse Events (PRO-CTCAE). Symptom monitoring was conducted every two weeks for patients with metastatic breast cancer undergoing chemotherapy. The primary outcome was the response rate to the ePROM system. The secondary outcomes were response time, item missing rate, and distribution of responses for each symptom. RESULTS: A total of 71 cases (mean age 52.6 years) were analyzed. Performance status was 0 in 76% of the cases and 1 or higher in 24%. First-line treatment was being administered in 30% of cases, second-line treatment in 17%, and third-line or higher treatment in 53%. The response rate to the ePROM system from registration to week 40 remained high at around 80%, indicating good compliance. The average response time was 5.5 min and the missing rate for each item was below 0.4%. Among 1,093 responses, the top 3 symptoms causing interference with daily life were Fatigue (63%), Numbness and tingling (48%), and General pain (46%). CONCLUSION: Our developed ePROM system was able to capture symptoms accurately in patients with metastatic breast cancer undergoing chemotherapy while maintaining a high response compliance.

After radical surgery for breast cancer, screening to diagnose recurrence in asymptomatic patients is not recommended. We retrospectively evaluated quality-adjusted survival. Included were fifty-seven recurrent breast cancer patients who died. Survival was partitioned into 3 health states by two different definitions: definition a) time with toxicities due to chemotherapy before progression (TOX1), time from the diagnosis of recurrence to progression without toxicities (TWiST1), and time from progression to death (REL1); definition b) time from the diagnosis of recurrence to death with toxicities (TOX2), without toxicities or hospitalization (TWiST2), and with hospitalization (REL2). Q-TWiST was calculated by multiplying the time in each health state by its utility (uTOX, uTWiST, and uREL). In threshold analyses, uTOX and uREL ranged from 0.0 to 1.0 whereas uTWiST was maintained at 1.0. We compared the patients with (n=32) and without (n=25) symptoms at the time of the diagnosis of recurrence. There was no difference in overall survival after primary surgery, although survival after the diagnosis of recurrence was significantly longer in the asymptomatic patients (p<0.01). Q-TWiST1 and Q-TWiST2 from the diagnosis of recurrence in the asymptomatic patients were significantly longer. Q-TWiST2 from primary surgery in the asymptomatic patients was significantly longer with some combinations of higher uTOX2 and lower uREL2. In conclusion, the asymptomatic detection of recurrence was associated with significantly longer quality-adjusted survival in comparison to symptomatic detection with some combinations of uTOX2 and uREL2. A prospective evaluation would clarify adequate follow-up methods after radical surgery for breast cancer.

PURPOSE: No standard approach other than oral care is available for preventing chemotherapy-induced stomatitis in patients with breast cancer. In this randomized, controlled phase 2 trial, we aimed to assess the efficacy and safety of a dexamethasone-based mouthwash in preventing chemotherapy-induced stomatitis in patients with early breast cancer. BASIC PROCEDURES: Patients with breast cancer scheduled for epirubicin and cyclophosphamide (EC) or docetaxel and cyclophosphamide (TC) therapy were selected and allocated in a 1:1 ratio to the intervention and control groups. The intervention group received chemotherapy, oral care, and a dexamethasone-based mouthwash, whereas the control group received chemotherapy and oral care. The primary endpoint was the incidence of stomatitis. This was a phase 2 study, and the significance level for the analysis of the primary endpoint was set a priori at 0.2. MAIN FINDINGS: Data pertaining to 58 patients in the control group and 59 patients in the intervention group were analyzed. Stomatitis incidence was 55% and 38% in the control and intervention groups, respectively (risk ratio, 0.68; 80% confidence interval, 0.52-0.88; Pâ¯=â¯.052). Stomatitis severity was lower in the intervention group than in the control group (Pâ¯=â¯.03). The proportion of patients who adhered to the mouthwash regimen was 87% (interquartile range, 67.8%-95.3%). No severe oral infections were observed. PRINCIPAL CONCLUSIONS: The dexamethasone-based mouthwash safely reduced stomatitis incidence and severity in patients receiving chemotherapy for early breast cancer. Phase 3 clinical trials are warranted for validating our results.

Loss of E-cadherin expression is a poor prognostic factor in patients with breast cancer. Breast cancer cells co-cultured with adipocytes reportedly promote E-cadherin attenuation and tumor progression. The current study aimed to investigate the association of reduced E-cadherin expression with adipose tissue invasion (ATI) and prognosis in breast cancer. Surgical specimens were collected from 188 women with invasive ductal carcinoma of the breast who had undergone surgery without neoadjuvant treatment. We compared E-cadherin expression in ATI and invasive front (IF) using immunohistochemistry with ImageJ. Reduced E-cadherin expression was detected not only in the ATI area but also in the IF, and the degree of reduced E-cadherin expression was positively correlated with both areas. In patients with lymph node metastasis compared to those without, E-cadherin expression was reduced and this reduction was associated with poor recurrence-free survival. We concluded that E-cadherin expression is reduced not only at the ATI area but also at the IF of the tumor. Reduced E-cadherin expression is a clear prognostic factor for breast cancer. Hence, future research is warranted for establishing an objective and quantitative E-cadherin staining assay that will allow clinical use of E-cadherin as a prognostic factor.

BACKGROUND/AIM: The prognosis of a cancer patient is influenced by the tumor-related factors, as well as by various patient-related factors. We evaluated the association between inflammatory and nutritional factors and their outcomes, including the prognosis and therapeutic course, in patients with metastatic breast cancer. PATIENTS AND METHODS: In this observational retrospective study, we evaluated 35 patients. The inflammatory and nutritional markers before systemic therapy included the lymphocyte count, neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), systemic immune-inflammatory index (SII), systemic inflammatory response index (SIRI), pan-immuno-inflammatory values (PIV), prognostic nutritional index (PNI), Glasgow prognostic score (GPS), and psoas muscle index (PMI). RESULTS: Triple-negative, low PNI, and GPS 2 were correlated with worse overall survival in the univariable analysis. The GPS was the only independent predictor of overall survival [hazard ratio=5.85, 95% confidence interval=1.15-29.68, p<0.01]. The time to treatment failure of first-line therapy in patients with GPS 2 was significantly shorter than that in patients with GPS 0/1 (p<0.01). CONCLUSION: The GPS was an independent predictive marker for overall survival in patients with metastatic breast cancer.

Systemic therapy for stage IV breast cancer is usually an initial treatment and is based on findings regarding biomarkers (e.g., hormone receptors and human epidermal growth factor receptor-2 [HER2]). However, the response to therapy and outcomes sometime differ among patients with similar prognostic factors including grade, hormone receptor, HER2, and more. We conducted retrospective analyses to evaluate the correlations between the overall survival (OS) of 46 stage IV breast cancer patients and (i) the peripheral absolute lymphocyte count (ALC) and (ii) composite blood cell markers. The peripheral blood cell markers included the neutrophil- to-lymphocyte ratio (NLR), the monocyte-to-lymphocyte ratio (MLR), the systemic immune-inflammation index (SII), the systemic inflammation response index (SIRI), and the most recently introduced indicator, the pan-immune-inflammatory value (PIV). The SIRI and PIV showed prognostic impacts on the patients: those with a low SIRI or a low PIV showed significantly better OS than those with a high SIRI (5-year, 66.0% vs. 35.0%, p<0.05) or high PIV (5-year, 68.1% vs. 38.5%, p<0.05), respectively. This is the first report indicating the possible prognostic value of the PIV for OS in patients with stage IV breast cancer. Further studies with larger numbers of patients are necessary for further clarification.

Taxanes are key drugs for patients with breast cancer. A major adverse effect of taxanes is peripheral neuropathy (PN). To investigate the ability of compression therapy using sleeves and stockings to prevent PN due to the taxane docetaxel, we conducted a single-center historical control trial. Patients receiving docetaxel at 75 mg/m2 every 3 weeks for 4 cycles as first-line chemotherapy for breast cancer were eligible. PN was evaluated using the common terminology criteria for adverse events version 4.0. The primary endpoint was the incidence of allgrade PN until 3 weeks after the fourth docetaxel administration. We evaluated 26 patients in the intervention group and compared their data to those collected retrospectively from 52 patients treated with docetaxel without compression. Neither the incidence of all-grade PN until 3 weeks after the fourth docetaxel administration (63.5% in the control group vs. 76.9% in the intervention group, p=0.31) nor that of PN grade ≥ 2 (13.5% vs. 15.4%, p=0.99) differed between the groups. In this study, the efficacy of compression therapy using sleeves and stockings to prevent PN induced by docetaxel was not demonstrated. Further clinical studies including medications or intervention are needed to reduce the incidence and severity of PN induced by chemotherapy.

In Japan, asymptomatic metastatic breast cancer (MBC) is often detected using tumor markers or imaging tests. We aimed to investigate differences in clinicopathological features, prognosis, and treatment between asymptomatic and symptomatic MBCs. Patients with MBC were retrospectively divided into asymptomatic and symptomatic groups to compare their prognosis by breast cancer subtype: luminal, human epidermal growth factor receptor 2 positive, and triple negative. Of 204 patients with MBC (114 asymptomatic, 90 symptomatic), the symptomatic group had a higher frequency of multiple metastatic sites and TN subtype. All cohorts in the asymptomatic group tended to or had longer post-recurrence survival (PRS) than those in the symptomatic group. In contrast, all cohorts and TN patients in the asymptomatic group tended to have or had longer overall survival (OS) than those in the symptomatic group, although no significant difference was observed in the luminal and HER2 subtypes. In the multivariate analysis, TN, recurrence-free survival, multiple metastatic sites, and symptomatic MBC were independently predictive of PRS. Regarding the luminal subtype, the asymptomatic group had longer chemotherapy duration than the symptomatic group, with no significant difference in OS between the groups. Asymptomatic and symptomatic MBCs differ in terms of subtypes and prognosis, and whether they require different treatment strategies for each subtype warrants further investigation.

Background: Lymphedema may develop when axillary lymph node dissection (ALND) injures and obstructs the lymph ducts in the upper limb. In patients with breast cancer, lymphedema is difficult to treat and can cause arm swelling, heaviness, and restricted movement. We aimed to identify the prevalence and risk factors for lymphedema after ALND in patients with breast cancer. Methods and Results: This retrospective study included 175 patients with breast cancer who underwent ALND in the Nagasaki University Hospital, Japan, between 2005 and 2018. Lymphedema was defined as symptomatic arm swelling with a >2-cm difference in the arm circumference between the affected and contralateral arms. Patients were divided into two groups according to the presence or absence of lymphedema. Surgical and pathological findings were compared between the two groups. Univariate and multivariate analyses were performed, including the chi-square test, Student's t-test, and logistic regression analysis. Lymphedema was prevalent in 20% of the study participants, and the mean time interval from surgery to development of lymphedema was 479 days. In the univariate analysis, a body mass index of >26 kg/m2, smoking, radiotherapy (RT), and dissection of >18 axillary lymph nodes (ALNs) significantly increased the risk of lymphedema. In the multivariate analysis, smoking, RT, and dissection of >18 ALNs significantly increased the risk of lymphedema. Conclusions: The prevalence of lymphedema in our study was 20%. Our findings suggest that smoking, RT, and dissection of >18 ALNs are risk factors for lymphedema. Aggressive and empiric ALND might be associated with axillary lymph duct damage.

Magnetic resonance cholangiopancreatography (MRCP) is a non-invasive imaging technique that provides high-quality visualization of the biliary tree, including the gallbladder. This study aimed to evaluate the useful-ness of preoperative MRCP for acute cholecystitis in predicting technical difficulties during laparoscopic chole-cystectomy (LC). A total of 168 patients who underwent LC with preoperative MRCP were enrolled in this study. Patients were divided into two groups according to preoperative MRCP findings: the visualized group (n = 126), in which the entire gallbladder could be visualized; and the non-visualized group (n = 42), in which the entire gallbladder could not be visualized. The perioperative characteristics and postoperative complica-tions of the two groups were retrospectively analyzed. Operation time was longer in the non-visualized group (median 101.5 vs. 143.5 min; p < 0.001). The non-visualized group had significantly more intraoperative blood loss than the visualized group (median 5 vs. 10 g; p = 0.05). The rate of conversion to open cholecystectomy was significantly higher in the non-visualized group (1.6 vs. 9.5%; p = 0.03). In conclusion, patients in the non- visualized group showed higher difficulty in performance of LC. Our MRCP-based classification is a simple and effective means of predicting difficulties in performing LC for acute cholecystitis.

Acute mesenteric ischemia (AMI) is often caused by superior mesenteric artery (SMA) embolization. We report a rare case of synchronous celiac axis and SMA embolization in an elderly woman with initially mild abdominal pain. Ultimately, a second contrast-enhanced computed tomography revealed extensive necrosis from the stomach to the transverse colon together with liver ischemia due to hours of occlusion. Multiorgan failure made palliation the only option, and she died the following evening. Autopsy revealed a fragile atherosclerosis-asso-ciated thrombus. Careful examination and repeat diagnostic tests should be performed in patients with mild abdominal symptoms at risk for AMI.

PURPOSE: The sequence of taxanes (T) followed by anthracyclines (A) as neoadjuvant chemotherapy has been the standard of care for almost 20 years for locally advanced breast cancer (LABC). Sequential administration of eribulin (E) following A/T could provide a greater response rate for women with LABC. METHODS: In this single-arm, multicenter, Phase II prospective study, the patients received 4 cycles of the FEC regimen and 4 cycles of taxane. After the A/T-regimen, 4 cycles of E were administered followed by surgical resection. The primary endpoint was the clinical response rate. Eligible patients were women aged 20 years or older, with histologically confirmed invasive breast cancer, clinical Stage IIIA (T2-3 and N2 only), Stage IIIB, and Stage IIIC, HER2-negative. RESULTS: A preplanned interim analysis aimed to validate the trial assumptions was conducted after treatment of 20 patients and demonstrated that clinical progressive disease rates in the E phase were significantly higher (30%) than assumed. Therefore, the Independent Data Monitoring Committee recommended stopping the study. Finally, 53 patients were enrolled, and 26 patients received the A/T/E-regimen. The overall observed clinical response rate (RR) was 73% (19/26); RRs were 77% (20/26) in the AT phase and 23% (6/26) in the E phase. Thirty percent (8/26) of patients had PD in the E phase, 6 of whom had achieved cCR/PR in the AT phase. Reported grade ≥ 3 AEs related to E were neutropenia (42%), white blood cell count decrease (27%), febrile neutropenia (7.6%), weight gain (3.8%), and weight loss (3.8%). CONCLUSION: Sequential administration of eribulin after the A/T-regimen provided no additional effect for LABC patients. Future research should continue to focus on identifying specific molecular biomarkers that can improve response rates.

BACKGROUND/AIM: Stage III breast cancer comprises a broad spectrum of disease, including the extent of supraclavicular/internal mammary lymph node metastasis. In this study, we evaluated the usefulness of the absolute lymphocyte count (ALC) and neutrophil-to-lymphocyte ratio (NLR) in predicting the prognosis of patients with stage III breast cancer. PATIENTS AND METHODS: Seventy-five patients with stage III breast cancer who underwent surgery were included. We compared their clinicopathological factors according to the presence or not of supraclavicular/internal mammary lymph node metastasis, and pretreatment ALC or NLR. RESULTS: Patients with metastasis of the studied lymph nodes had a poorer prognosis in comparison to those without metastasis. In patients without these types of lymph node metastasis, both the ALC and NLR were predictive factors for relapse-free and overall survival. Among these patients, those with a low ALC or high NLR had recurrence-free and overall survival comparable to those of patients with supraclavicular/internal mammary lymph node metastasis. CONCLUSION: Pretreatment ALC and NLR were prognostic factors for patients with stage III breast cancer.

INTRODUCTION: Although aromatase inhibitors (AIs) are typical drugs for cancer treatment-induced bone loss, their effects on the bone microstructure remain unclear. In this study, we evaluated changes in the bone mineral density (BMD) and bone microstructure associated with AI treatment using high-resolution peripheral quantitative computed tomography (HR-pQCT) in patients with early breast cancer. MATERIALS AND METHODS: This prospective, single-arm, observational study included non-osteoporotic, postmenopausal women with hormone receptor-positive breast cancer. Patients underwent dual-energy X-ray absorptiometry (DXA), HR-pQCT, and tartrate-resistant acid phosphatase-5b (TRACP-5b) or procollagen type-I N-terminal propeptide measurements at baseline and 6 and 12 months after AI therapy. The primary endpoint was changes in the total volumetric BMD (Tt.vBMD), trabecular vBMD (Tb.vBMD), and cortical vBMD (Ct.vBMD) longitudinally at the distal radius and tibia. RESULTS: Twenty women were included (median age 57.5 years; range 55-72 years). At 12 months, HR-pQCT indicated a significant decrease in the Tt.vBMD (median distal radius - 5.3%, p < 0.01; distal tibia - 3.2%, p < 0.01), Tb.vBMD (- 3.2%, p < 0.01; - 1.0%, p < 0.05, respectively), and Ct.vBMD (- 3.2%, p < 0.01; - 2.7%, p < 0.01, respectively). Estimated bone strength was also significantly decreased. The DXA BMD value in the total hip (p < 0.01) and femoral neck (p = 0.03), but not in the lumbar spine, was significantly decreased. The TRACP-5b levels was significantly negatively associated with changes in the Tt.vBMD in both the distal radius and tibia (r = - 0.53, r = - 0.47, respectively) CONCLUSION: Postmenopausal women who received AIs for early breast cancer experienced significant trabecular and cortical bone deterioration and a decrease in estimated bone strength within only 1 year.

Survival of patients with breast cancer can be prolonged by treatment with drugs, particularly new molecular-targeted drugs. However, these agents can be expensive and such treatments can be "an economic burden." In this ongoing trial, we aim to assess the usefulness of ChemoCalc, a software package for calculating drug costs, to help patients understand the financial outlays. In this multicenter, randomized controlled phase 2 trial, 106 patients with advanced breast cancer will be assigned to either the "ChemoCalc" or "Usual Explanation" group. Treatment using ChemoCalc will be discussed with patients in the ChemoCalc group, whereas standard treatments, without using ChemoCalc, will be discussed with patients in the Usual Explanation group. Subsequently, the participants will decide the treatment and complete a five-grade evaluation questionnaire; those in the Usual Explanation group will receive information about ChemoCalc. Investigators will report if patients subsequently decide to change treatments. The primary endpoint will be the scores of two key questions compared between the groups: "Did you understand the cost of treatment in today's discussion?" and "Do you think the cost of treatment is important in choosing a treatment?". The secondary endpoints will be to compare discrepancies between treatments recommended by physicians and those selected by patients, the time required for discussion, other questionnaire factors, and the relationship between Comprehensive Score for Financial Toxicity tool and treatment selection. This will be the first randomized controlled trial to assess the efficacy of software to help patients understand drug cost estimates and whether it subsequently affects treatment choice. This study will be conducted according to the CONSORT statement. All participants will sign a written consent form. The study protocol was reviewed and approved by the Clinical Research Review Board of Nagasaki University (19070801). The protocol (version 1) was designed and will be conducted in accordance with the Declaration of Helsinki (1964) and the Ethical Guidelines for Medical and Health Research Involving Human Subjects (2017). The findings will be disseminated through scientific and professional conferences, and in peer-reviewed journals.

ABSTRACT
Knowledge of anatomical variations of the celiac axis is important in upper abdominal surgery. Aberrant common hepatic artery originating from the left gastric artery without connecting the gastroduodenal artery is extremely rare. Preoperative vascular anatomy assessment using reconstructions of CT images may be useful for safe surgical procedure.
ABSTRACT
Taxanes are key drugs for patients with breast cancer. A major adverse effect associated with the administration of the taxane docetaxel is chemotherapy-induced peripheral neuropathy (CIPN). We are conducting a singlecenter, single-arm, open-label historical control trial to evaluate the ability of compression therapy using stockings or sleeves to prevent CIPN due to docetaxel treatment. The primary endpoint is the incidence of all-grade CIPN according to patients' records until 3 weeks after the fourth docetaxel administration. This study's results will clarify whether compression therapy using stockings or sleeves can prevent CIPN in breast cancer patients.

BACKGROUND: Pancreatic neuroendocrine tumors (PNETs) are typically solid neoplasms but, in very rare cases, present as cystic lesions. We describe a case of a cystic neuroendocrine tumor that developed as a small cystic lesion. CASE PRESENTATION: In 2011, a 66-year-old Japanese woman underwent computed tomography (CT) that revealed a cystic lesion in the tail of the pancreas measuring 9 mm. She did not have any symptoms. She underwent a CT scan every year thereafter. The cystic lesion gradually increased and was 40 mm in 2019; endoscopic retrograde pancreatography (ERP) was then performed. Cytological examination demonstrated class IIIb adenocarcinoma, and we conducted laparoscopic distal pancreatectomy. Pathological examination showed PNET. CONCLUSION: Although cystic change of PNET is generally caused by ischemia or necrosis inside the tumor, in our case, PNET occurred as a small cyst that increased without changing form.
ABSTRACT
This multicenter phase II N-DOCC-F-C-1701 trial is being planned in order to investigate the efficacy and safety of CPT-11+S-1 +Ramucirumab (IRIS+Rmab), which is anticipated to have a stronger anti-tumor effect than IRIS+Bmab in patients with metastatic colorectal cancer (mCRC) previously treated with oxaliplatin (L-OHP) containing regimen, in consideration of the result of RAISE, FIRIS and some phase II trials of IRIS+Bevacicizumab (Bmab). The number of patients is set at 38 for the statistical analysis, assuming an expected median PFS of 5.0 months (threshold: 3.0 months). The primary endpoint of the study is the progression free survival (PFS), and the secondary endpoints are the overall response rate (ORR), overall survival (OS), adverse events (AE), quality of life (QOL) and review of nausea and vomiting. This trial is registered in the UMIN Clinical Trials Registry as UMIN000028170. We intend to start conducting the trial in September 1, 2017. If this trial meets the endpoint, IRIS+Rmab might be supported as a new optional standard regimen for mCRC.

We assessed the usefulness of ChemoCalc, a software package for calculating drug costs, in helping patients understand these costs. We randomly assigned, in a 1 : 1 ratio, 20 women who had undergone surgery for early breast cancer to a group that discussed adjuvant treatment with their physicians using the ChemoCalc software (ChemoCalc group) or a group that discussed adjuvant treatment without ChemoCalc (Usual Explanation group). The participants completed a five-grade evaluation questionnaire after these discussions. The primary endpoint was the intergroup comparison of the questionnaire scores regarding participants' understanding of their treatment-associated drug costs. Median age was not significantly different between the ChemoCalc group and Usual Explanation group (57 vs. 50, respectively; p=0.27). Patients in the ChemoCalc group had a significantly higher perceived level of understanding of the drug cost than those in the Usual Explanation group (5 [4-5] vs. 2.5 [1-5], respectively; p=0.002). Scores related to the patients' perception that understanding drug costs is an important part of breast cancer treatment were also higher in the ChemoCalc group than the Usual Explanation group (5 [2-5] vs. 3 [1-5], respectively; p=0.049). ChemoCalc was found to be useful for understanding drug costs.
