Background: The number of hospital-based palliative care consultation teams (PCCTs) has increased in Japan, and quality improvement (QI) of PCCTs is an issue. The Japanese Society for Palliative Medicine is building a framework for continuous QI of PCCT activities. Objective: The objective of this study was to develop a program to support QI for PCCTs, and to describe the initial experience with the program. Design: The report details the development of a self-check program, followed by a one-year follow-up observational survey. Methods: We developed a self-check program using the concept of the Plan-Do-Check-Act (PDCA) cycle and a multidisciplinary expert panel. A total of 114 PCCTs entered the program in the first year. Results: We developed three forms for the CHECK, ACT-PLAN, and DO phases aligned with the PDCA cycle. The forms consisted of 34 items across 8 domains. A total of 83 PCCTs (729 members) returned the CHECK, ACT-PLAN forms, and 41 PCCTs returned the DO forms after one year. Overall, 213 high priority issues were identified in the ACT phase. The issues of many PCCTs were "Sharing goals of care is inadequate within the PCCT (33%)" and "Sharing goals of care is inadequate between patient/family or primary team and the PCCT (28%)." Improvements in identified issues were: "achieved" 23% and "almost achieved" 48% after one year. Conclusions: We developed a self-check program to support QI efforts for hospital-based PCCTs. The priority issues among PCCTs and improvement goals with examples were identified. These results will support ongoing efforts to develop a continuous improvement model for QI of PCCTs.

The clinicopathological and immunohistochemical characteristics of clinically occult extrapulmonary lymphangioleiomyomatosis in lymph nodes (LN-LAM) being dissected during surgical staging of pelvic malignancy have not been well investigated. We assessed samples from nine female patients (median age, 61). None had past or familial history of tuberous sclerosis and had LAM lesions other than LN such as lung. The primary malignancies included four endometrial endometrioid carcinomas, one endometrial carcinosarcoma, three ovarian serous carcinomas and one urothelial carcinoma. Median follow-up was 43 months. The number of affected LNs ranged from 1 to 15 (median, 2) with sizes ranging from 1 to 13 mm (median, 3.0). Six cases had clinically occult LN-LAM only within the pelvic LNs, two only within para-aortic LNs, and one within both pelvic and para-aortic lymph nodes. Immunohistochemically, LAM cells exhibited a strong diffuse positivity for β-catenin and E-cadherin in all nine cases. Clinically occult LN-LAM mainly affects peri- or post-menopausal women. On rare occasions, occult LN-LAM may manifest as systemic LAM, including in the lung. β-catenin and E-cadherin carry potential utility as additional diagnostic markers.

In patients with femoral intertrochanteric fractures treated by cephalomedullary (CM) nailing, abduction force reportedly decreased by 25-30% during the postoperative follow-up period. The purpose of the current study is to evaluate the cross-sectional area (CSA) and adipose tissue ratio (ATR) of the gluteus medius muscle on the postoperative computed tomography (CT) view, expecting this graphic study will support clinical results. A total of 27 patients with femoral intertrochanteric fractures treated by CM femoral nail implants completed the study. The mean age at osteosynthesis was 83 years (range: 72-94 years). The mean postoperative follow-up period was 23 months. The three CT axial slice views were defined as slices A, B, and C corresponding to proximal, midway, and distal part of gluteus medius, respectively. The CSA and ATR were assessed bilaterally. The mean and standard deviation of CSA values (mm2) between the nonoperated/ operated side were as follows: slice A: 2225.8 ± 621.2/1984.5 ± 425.8; slice B: 2145.1 ± 538.3/1854.9 ± 383.9; and slice C: 1711.0 ± 459.0/1434.5 ± 396.9 ( p < 0.01 in slices A, B, and C). The mean and standard deviation of ATR values (%) from the nonoperative/ operative side were as follows: slice A: 2.8 ± 1.7/5.2 ± 3.5; slice B: 2.7 ± 1.9/4.6 ± 3.2; and slice C: 3.6 ± 3.0/4.8 ± 3.2 ( p < 0.01 in slices A and B and p < 0.05 in slice C). Our image findings documented that gluteus medius is significantly changed in CSA and ATR. The damage possibly triggers decrease in muscular strength of hip abduction in the postoperative follow-up period. This measurement is objective, and needed no patient's endurance and cooperation.

Abstract BACKGROUND and AIM: Findings from a randomized phase 2 JONIE1 trial in women with HER2-negative early breast cancer have shown that the addition of zoledronic acid (ZOL) to neoadjuvant chemotherapy (CT) has potential anticancer benefits in postmenopausal and triple-negative breast cancer patients. We report the data for the prespecified secondary endpoint of disease-free survival (DFS). METHODS: We enrolled women with HER2-negative early breast cancer and randomly assigned them to receive CT or CT+ZOL (CTZ). All patients received 4 cycles of FEC100 (fluorouracil 500 mg/m2, epirubicin 100 mg/m2, and cyclophosphamide 500 mg/m2), followed by 12 cycles of paclitaxel at 80 mg/m2 weekly. ZOL (4 mg) was administered 3-4 times weekly for 7 weeks to the CTZ group patients. Definitive surgery was performed 3-4 weeks after the last paclitaxel dose. The primary endpoint was pathological complete response (pCR). The secondary endpoints were the clinical response rates, rate of breast-conserving surgery, safety, and DFS (defined as the time from randomization to disease occurrence or death). The trial is registered as UMIN000003261 (www.umin.ac.jp/english/) with ongoing follow-up. FINDINGS: Of the 188 patients enrolled, 95 were assigned to the CT group and 93 to the CTZ group. The mean (95% CI) DFS time of the CT group was 5.15 years (4.83-5.47) and that of the CTZ group was 5.38 years (5.11-5.66). The 3-year DFS rate was 84.6% (95% CI 77.2-92.0) in the CT group and 90.7% (84.6-96.8) in the CTZ group with no significant difference (p = 0.120). The particular benefit from ZOL for the neoadjuvant CT seen as improvement of the pCR rate was indicated in the 3-year DFS period for triple-negative cancer cases (CT vs CTZ: 70.6% vs 94.1%), but not for postmenopausal cases. CONCLUSIONS: ZOL slightly improved DFS when combined with CT. Although a significant difference was not found in this study, plans are underway for conducting a combined analysis of 3 neoadjuvant CT trials together with ZOL. The improvement of the pCR rate may be associated with DFS in triple-negative cases. Previous studies have shown that ZOL was more efficacious in an estrogen-suppressed condition. However, the short-term application of ZOL in this study may not be sufficient to improve the outcome in postmenopausal patients.

Telaprevir, a non-structural (NS)3/4A protease inhibitor, is a direct-acting antiviral drug that inhibits viral replication. Triple therapy with telaprevir, pegylated interferon, and ribavirin is a standard therapeutic regimen for patients with genotype 1b chronic hepatitis C virus (HCV) infection and a high viral load. Several factors, including mutations in the NS5A gene, are important predictors of the efficacy of interferon therapy. In this study, we examined the mutational diversity of NS5A and its impact on the efficacy of triple therapy. We enrolled patients with genotype 1b chronic HCV infection and a high viral load (31 males/17 females; mean age, 57.6 years), who were treated with triple therapy. This study was conducted at Kobe University Hospital and at three affiliated hospitals in Hyogo prefecture, Japan, between November 2011 and June 2013. A sustained viral response after 12 weeks (SVR12) was achieved in 37/48 patients (77%). Based on intent-to-treat analysis, SVR12 was significantly greater in patients with the major allele than in those with the minor allele for the IL28B single nucleotide polymorphism (SNP; 88 vs. 56%; P<0.05). The prevalence of the V2334I mutation in NS5A was significantly higher in patients who achieved SVR12, while that of G2356E was significantly higher in patients who did not achieve SVR12 (P<0.05). Mutations in the NS3 region that are thought to confer resistance to telaprevir were detected in 3/27 patients who achieved SVR12 (Val36, n=3) and in 5/10 patients who did not achieve SVR12 (Val36, n=4; Thr54, n=1). In conclusion, the IL28B SNP and mutations in the NS5A region were associated with the therapeutic response to triple therapy. Half of the patients who did not achieve SVR12 had mutations conferring resistance to telaprevir. However, pre-existing mutations in NS3 did not affect the efficacy of triple therapy.

Abstract Background: Endocrine treatment-related adverse events have a strong impact on patients’ quality of life and sometimes result in treatment discontinuation. Since joint symptoms are the most frequently recognized side-effect of aromatase inhibitors, evaluation of associated risk factors may well be important. Among high body mass index (BMI) and chemotherapy have been associated with the development of joint symptoms in patients enrolled in ATAC trials. To determine the impact of these factors on treatment-emergent joint symptoms in Japanese breast cancer treated with adjuvant anastrozole, we conducted a prospective cohort study based on patient-reported outcomes (PROs). Patients and Methods: Postmenopausal Japanese women with estrogen receptor-positive breast cancer and treated with adjuvant anastrozole were enrolled in this prospective cohort study (SAVS-JP, UMIN000002455). A total of 416 patients were recruited from 30 centers for PRO assessment at their after-care appointments between August 2009 and April 2012. Patients completed the self-report questionnaire at baseline, 3, 6, 9 and 12 months. Symptoms were assessed as four categories (none, Grade 1: somewhat, Grade 2: quite a bit, Grade 3: very much). Pre-existing symptoms were only included if they worsened from baseline. The endpoint of this study was the frequencies of treatment-related joint symptoms, which included reports of arthralgia, decrease of joint motion, and joint stiffness. Results: We obtained PROs from 391 (94.0%) of the 416 patients at baseline and at one or more points during treatment, so that 391 patients were analysed. Joint symptoms at baseline were reported by 134 (34.3%) patients and new or worsening symptoms were experienced by 258 (66.0%) patients. The symptoms were graded as: grade 1, 53.1%; grade 2, 37.6%; grade 3, 9.3%. Mean time to onset of joint symptoms was 5.4 months, and nearly 80% had developed symptoms by 6 months. Twelve patents discontinued treatment during the first year and two patients withdrew due to joint symptoms. Patients with joint symptoms were significantly younger (age: 63.1; standard deviation: 7.9) than those without symptoms (age: 65.8: 8.4; p = 0.0045). We categorized BMI into three groups (low: &amp;lt;25, intermediate: 25-30, high: 30mg/m2&amp;lt;), but there were no significant relationships between BMI and joint symptoms. While joint symptoms were not significantly associated with neoadjuvant chemotherapy, patients treated with adjuvant chemotherapy (68 patients) reported a significantly higher frequency than did those not treated with adjuvant chemotherapy (83.8% vs 63.0%; p = 0.001). Discussion: The incidence of anastrozole-associated joint symptoms was more than 60%, with most women having developed symptoms by 6 months. The PROs may disclose higher prevalence rates than physician ratings for symptoms published in pivotal clinical trials. We found that younger age and adjuvant chemotherapy, but not high BMI, were significantly associated with joint symptoms. These data should prove useful for counseling before initiating treatment with adjuvant aromatase inhibitors for postmenopausal Japanese women.
