The aim of this study was to identify the effects of a communication skills training (CST) program for oncologists, developed based on patient preferences regarding oncologists' communication.
Thirty ...oncologists were randomly assigned to either an intervention group (IG; 2-day CST workshop) or control group (CG). Participants were assessed on their communication performance during simulated consultation and their confidence in communicating with patients at baseline and follow-up. A total of 1,192 patients (response rate, 84.6%) who had consultations with the participating oncologists at baseline and/or follow-up were assessed regarding their distress using the Hospital Anxiety and Depression Scale, satisfaction with the consultation, and trust in their oncologist after the consultation.
At the follow-up survey, the performance scores of the IG had improved significantly, in terms of their emotional support (P = .011), setting up a supportive environment (P = .002), and ability to deliver information (P = .001), compared with those of the CG. Oncologists in the IG were rated higher at follow-up than those in the CG in terms of their confidence in themselves (P = .001). Patients who met with oncologists after they had undergone the CST were significantly less depressed than those who met with oncologists in the CG (P = .027). However, the CST program did not affect patient satisfaction with oncologists' style of communication.
A CST program based on patient preferences is effective for both oncologists and patients with cancer. Oncologists should consider CST as an approach to enhancing their communication skills.
In metastatic or recurrent cervical cancer, cisplatin-based chemotherapy is standard. The JCOG0505 randomized phase III trial evaluated the clinical benefits of carboplatin-based regimen.
Eligible ...patients had metastatic or recurrent cervical cancer and had ≤ one platinum-containing treatment and no prior taxane. Patients were randomly assigned either to conventional paclitaxel plus cisplatin (TP; paclitaxel 135 mg/m(2) over 24 hours on day 1 and cisplatin 50 mg/m(2) on day 2, repeated every 3 weeks) or paclitaxel plus carboplatin (TC; paclitaxel 175 mg/m(2) over 3 hours and carboplatin area under curve 5 mg/mL/min on day 1, repeated every 3 weeks). Primary end point was overall survival (OS). Planned sample size was 250 patients to confirm the noninferiority of TC versus TP with the threshold hazard ratio (HR) of 1.29.
Between February 2006 and November 2009, 253 patients were enrolled. The HR of OS was 0.994 (90% CI, 0.79 to 1.25; noninferiority P = .032 by stratified Cox regression). Median OS was 18.3 months with TP versus 17.5 months with TC. Among patients who had not received prior cisplatin, OS was shorter with TC (13.0 v 23.2 months; HR, 1.571; 95% CI, 1.06 to 2.32). One treatment-related death occurred with TC. Proportion of nonhospitalization periods was significantly longer with TC (P < .001).
TC was noninferior to TP and should be a standard treatment option for metastatic or recurrent cervical cancer. However, cisplatin is still the key drug for patients who have not received platinum agents.
Summary Background The primary analysis of the JGOG 3016 trial showed that a dose-dense paclitaxel and carboplatin regimen significantly improves progression-free and overall survival compared with ...the conventional regimen as first-line chemotherapy for patients with epithelial ovarian, fallopian tube, or primary peritoneal cancer. We report the long-term follow-up results for survival. Methods This randomised controlled trial was done at 85 centres in Japan. Patients with stage II–IV ovarian cancer were randomly assigned to receive conventional treatment (carboplatin area under the curve AUC 6 mg/mL per min and paclitaxel 180 mg/m2 on day 1) or dose-dense treatment (carboplatin AUC 6 mg/mL per min on day 1 and paclitaxel 80 mg/m2 on days 1, 8, and 15). The treatments were repeated every 3 weeks for six cycles; responding patients had three additional cycles. The randomisation was done centrally by telephone or fax, stratified by residual disease, stage, and histological type. The primary endpoint was progression-free survival; overall survival was a secondary endpoint. Long-term information on adverse events was not collected. Efficacy analyses were by intention to treat. This study is registered with ClinicalTrials.gov , number NCT00226915. Findings 637 patients were enrolled, of whom 631 were analysed (312 assigned to the dose-dense regimen, 319 to the conventional regimen). Median follow-up was 76·8 months (IQR 68·9–85·6). Median progression-free survival was significantly longer in the dose-dense treatment group than in the conventional treatment group (28·2 months 95% CI 22·3–33·8 vs 17·5 months 15·7–21·7; hazard ratio HR 0·76, 95% CI 0·62–0·91; p=0·0037). Median overall survival was 100·5 months (95% CI 65·2–∞) in the dose-dense treatment group and 62·2 months (52·1–82·6) in the conventional treatment group (HR 0·79, 95% CI 0·63–0·99; p=0·039). Interpretation Dose-dense treatment offers better survival than conventional treatment and is a potential new standard of care for first-line chemotherapy for patients with advanced epithelial ovarian cancer.

Measurements of insulin-like growth factor-I (IGF-I) are useful not only for diagnosis and management of patients with growth hormone (GH)-related disorders but also for assessing nutritional status. ...We reported population-based references of serum IGF-I in 1996. However, they did not properly reflect data in the transition period from puberty to maturity. The aim of the present study was to re-establish a set of normative data for IGF-I for the Japanese population. The study included 1,685 healthy Japanese subjects (845 males, 840 females) from 0 to 83 years old. Subjects suffering from diseases that could affect IGF-I levels were excluded. Obese or extremely thin adult subjects were also excluded. IGF-I concentrations were determined by commercially available immunoradiometric assays. The reference intervals were calculated using the LMS method. Median IGF-I levels reached 310 ng/mL in males at the age of 14 years and 349 ng/mL in females at the age of 13 years, falling to 124 ng/mL and 103 ng/mL, respectively, by the age of 70 years. The mean pretreatment IGF-1 SD scores in patients with severe GH deficiency (GHD) obtained from the database of the Foundation for Growth Science and from clinical studies for adult GHD were -2.1±1.6 and -4.9±2.5, respectively. The present study established age- and gender-specific normative IGF-I data for the Japanese population and showed the utility of these references for screening patients with severe GHD.
Nivolumab is a human monoclonal antibody against the immune checkpoint receptor programmed death‐1, inhibiting binding to programmed death‐ligand 1 or 2 (PD‐L1 or PD‐L2). This phase 2 study evaluated ...the efficacy and safety of nivolumab in patients with advanced/recurrent uterine cervical cancer, uterine corpus cancer, or soft tissue sarcoma (STS). Patients received nivolumab 240 mg at 2‐week intervals. Primary endpoint was objective response rate; secondary endpoints included overall survival, progression‐free survival, and safety. PD‐L1 expression and microsatellite‐instability (MSI) status were analyzed as potential efficacy biomarkers. Objective response rate was 25%, 23%, and 0% in patients with cervical cancer (n = 20), corpus cancer (n = 22), and STS (n = 21), respectively. The lower 80% confidence intervals of objective response rates in patients with cervical or corpus cancer exceeded the threshold rate (5%); the primary endpoint was met in cervical and corpus cancer, but not in STS. Median progression‐free survival was 5.6, 3.4, and 1.4 months, and 6‐month overall survival was 84%, 73%, and 86% in cervical cancer, corpus cancer, and STS, respectively. The objective response rate was higher in patients with cervical cancer with PD‐L1‐positive (n = 5/15; 33%) versus PD‐L1‐negative (n = 0/5; 0%) tumors. The two patients with corpus cancer classified as MSI‐high responded; the six patients classified as microsatellite stable did not respond. Overall, nivolumab showed acceptable toxicity in all cohorts, with evidence of clinical activity in uterine cervical or corpus cancer, but not in STS. PD‐L1 expression in cervical cancer and MSI‐high in corpus cancer may predict clinical activity of nivolumab in these cancers.
The present study of the programmed death‐1 inhibitor nivolumab showed acceptable toxicity in all cohorts, with evidence of clinical activity in patients with advanced/recurrent uterine cervical or corpus cancer, but not in those with soft tissue sarcoma. Programmed death‐ligand 1 expression in cervical cancer, and microsatellite instability‐high in corpus cancer, may predict clinical activity of nivolumab.
Summary Background Paclitaxel and carboplatin given every 3 weeks is standard treatment for advanced ovarian carcinoma. Attempts to improve patient survival by including other drugs have yielded ...disappointing results. We compared a conventional regimen of paclitaxel and carboplatin with a dose-dense weekly regimen in women with advanced ovarian cancer. Methods Patients with stage II to IV epithelial ovarian cancer, fallopian tube cancer, or primary peritoneal cancer were eligible for enrolment in this phase 3, open-label, randomised controlled trial at 85 centres in Japan. Patients were randomly assigned by computer-generated randomisation sequence to receive six cycles of either paclitaxel (180 mg/m2 ; 3-h intravenous infusion) plus carboplatin (area under the curve AUC 6 mg/mL per min), given on day 1 of a 21-day cycle (conventional regimen; n=320), or dose-dense paclitaxel (80 mg/m2 ; 1-h intravenous infusion) given on days 1, 8, and 15 plus carboplatin given on day 1 of a 21-day cycle (dose-dense regimen; n=317). The primary endpoint was progression-free survival. Analysis was by intention to treat (ITT). This trial is registered with ClinicalTrials.gov , number NCT00226915. Findings 631 of the 637 enrolled patients were eligible for treatment and were included in the ITT population (dose-dense regimen, n=312; conventional regimen, n=319). Median progression-free survival was longer in the dose-dense treatment group (28·0 months, 95% CI 22·3–35·4) than in the conventional treatment group (17·2 months, 15·7–21·1; hazard ratio HR 0·71; 95% CI 0·58–0·88; p=0·0015). Overall survival at 3 years was higher in the dose-dense regimen group (72·1%) than in the conventional treatment group (65·1%; HR 0·75, 0·57–0·98; p=0·03). 165 patients assigned to the dose-dense regimen and 117 assigned to the conventional regimen discontinued treatment early. Reasons for participant dropout were balanced between the groups, apart from withdrawal because of toxicity, which was higher in the dose-dense regimen group than in the conventional regimen group (n=113 vs n=69). The most common adverse event was neutropenia (dose-dense regimen, 286 92% of 312; conventional regimen, 276 88% of 314). The frequency of grade 3 and 4 anaemia was higher in the dose-dense treatment group (214 69%) than in the conventional treatment group (137 44%; p<0·0001). The frequencies of other toxic effects were similar between groups. Interpretation Dose-dense weekly paclitaxel plus carboplatin improved survival compared with the conventional regimen and represents a new treatment option in women with advanced epithelial ovarian cancer.

Background
The long-term outcomes and risk factors of paclitaxel-induced peripheral neuropathy (PIPN) have not yet been fully elucidated.
Methods
We identified 219 breast cancer patients who received ...paclitaxel as adjuvant chemotherapy between 2002 and 2009. We retrospectively analyzed the incidence, time to onset, duration, and risk factors for PIPN by chart review.
Results
Of the 219 patients, 212 developed PIPN (97%) during a median follow-up time of 57 months (range 5.3–95.5). Median time to PIPN onset was 21 days (range 11–101) for the entire patient population: 35 days (range 14–77) for weekly administration and 21 days (range 11–101) for tri-weekly administration. PIPN caused termination of paclitaxel treatment in 7 patients (4%). Median duration of PIPN was 727 days (range 14–2621 days). PIPN persisted in 64 and 41% of patients at 1 and 3 years after initiating paclitaxel, respectively. Age ≥60 years and severity of PIPN were significantly associated with PIPN duration.
Conclusions
PIPN persists longer in older patients and in those who experience severe neuropathy. Further studies to identify the risk factors for PIPN are warranted.
Aprepitant is a new neurokinin‐1 (NK1) receptor antagonist developed as a treatment for chemotherapy‐induced nausea and vomiting (CINV). To evaluate the efficacy and safety of aprepitant used in ...combination with standard therapy (granisetron and dexamethasone), we conducted a multicenter, phase II, placebo‐controlled, double‐blind, randomized study in Japanese cancer patients who received cancer chemotherapy including cisplatin (≥70 mg/m2). Aprepitant was administered for 5 days. A total of 453 patients were enrolled. In the three study groups, (i) standard therapy, (ii) aprepitant 40/25 mg (40 mg on day 1 and 25 mg on days 2–5) and (iii) aprepitant 125/80 mg (125 mg on day 1 and 80 mg on days 2–5), the percentage of patients with complete response (no emesis and no rescue therapy) was 50.3% (75/149 subjects), 66.4% (95/143 subjects) and 70.5% (103/146 subjects), respectively. This shows that efficacy was significantly higher in the aprepitant 40/25 mg and 125/80 mg groups than in the standard therapy group (χ2 test closed testing procedure: P = 0.0053 and P = 0.0004, respectively) and highest in the aprepitant 125/80 mg group. The delayed phase efficacy (days 2–5) was similar to the overall phase efficacy (days 1–5), indicating that aprepitant is effective in the delayed phase when standard therapy is not very effective. In terms of safety, aprepitant was generally well tolerated in Japanese cancer patients. (ClinicalTrials.gov number, NCT00212602.) (Cancer Sci 2010; 101: 2455–2461)
Background
This study aimed to determine the incidence of pelvic fistulas in cervical cancer patients treated with bevacizumab in Japanese clinical practice.
Methods
A post-marketing surveillance ...(PMS) study was conducted between June 2016 and February 2018 to survey physicians who treated advanced or recurrent cervical cancer patients with bevacizumab (according to the product label). The clinical/treatment status of patients with pelvic fistulas was assessed in an additional retrospective case series study.
Results
142 patients were included in the PMS study (median age 51 years; 66.9% squamous cell carcinoma; 66.2% recurrent cervical cancer; 64.1% previous radiotherapy). Patients received a median of seven bevacizumab doses. Six patients, all of whom had a history of pelvic irradiation, developed seven fistulas (4.2%; 95% confidence interval, 1.56–8.96), and five patients had also undergone pelvic surgery. The case series study of the patients who developed fistulas indicated that three patients had high cumulative bladder and rectal doses of radiation, and two of them had undergone salvage re-irradiation for pelvic recurrence. The other three patients underwent both radical hysterectomy and adjuvant radiotherapy, but did not receive an excessive radiation dose to the bladder or rectum.
Conclusions
This study found that the upper limit of the 95% confidence interval for pelvic fistula incidence did not exceed the incidence reported in the GOG 240 study. To ensure an adequate benefit-risk assessment of bevacizumab in cervical cancer patients, a comprehensive evaluation of prior treatment is essential and the possibility of unexpected fistulas, even after careful evaluation, should be considered.
