Background There is no standard chemotherapy available for unresectable or metastatic small bowel adenocarcinoma (SBA) because of its rarity. This systematic review aims to assess the efficacy and safety of chemotherapy for patients with unresectable or metastatic SBA. Methods In accordance with the PRISMA statements, literature search was conducted using PubMed, Scopus, and the Cochrane Central Register of Controlled Trials. The included studies were prospective randomized, nonrandomized, or observational studies. Risk of bias was assessed the ROBINS-I tool. Results Seven prospective single-arm Phase II studies were included in this review. Six of them were assessed as having a moderate risk of bias and one as having a serious risk of bias. A meta-analysis was not performed, because the studies were single-arm. Systemic chemotherapy based on fluoropyrimidine regimens achieved favorable outcomes with acceptable adverse effects as a first therapy; however, the regimens differed in each study. The object response rate was 18-50%, and the disease control rate was 29-87%. With 5-fluorouracil, adriamycin, and mitomycin-C regimen, one treatment-related death occurred. A second line of therapy including chemotherapy with nab-paclitaxel also showed favorable efficacy. The object response rate was 20%, and the disease control rate was 50%. Conclusions Systemic chemotherapy based on fluoropyrimidine regimens was mainly used for unresectable or metastatic SBA. While it may achieve favorable outcomes with acceptable adverse effects, further evidence is needed.Background Tisagenlecleucel demonstrated a high rate of durable response in adult patients with relapsed/refractory (r/r) diffuse large B-cell lymphoma (DLBCL) in the pivotal global phase 2 JULIET study. Here, we report the efficacy and safety of tisagenlecleucel in the Japanese subgroup. Methods JULIET (NCT02445248) is a single-arm, open-label, multicenter, phase 2 study involving adult patients with r/r DLBCL who either relapsed after or were ineligible for autologous stem cell transplant. Primary endpoint was best overall response rate (ORR; complete response [CR] + partial response [PR]) as judged by an independent review committee. Results In Japan, of 17 patients enrolled, 9 were infused with tisagenlecleucel and completed ≥ 3 months of follow-up. Best ORR was 77.8% (7/9; 95% confidence interval, 40.0-97.2), with 5 patients (55.6%) in CR and 2 (22.2%) in PR. Cytokine release syndrome (CRS) occurred in 6 patients (66.7%), with grade 3 CRS in 2 patients (Penn grading scale). Two patients received tocilizumab. Two deaths (22.2%) occurred more than 30 days after tisagenlecleucel infusion due to disease progression, neither of which were related to tisagenlecleucel. Conclusion Tisagenlecleucel showed a high best ORR with a manageable safety profile, thus offering a new treatment option in selected Japanese patients with r/r DLBCL.We hypothesized that the baseline FRAX score and previous falls would predict the incidence of sarcopenia in community-dwelling older adults who received medical check-ups. The FRAX score (hazard ratio [HR] = 1.087, 95% CI 1.014-1.167) and previous falls (HR = 5.181, 95% CI 1.002-26.777) were determined to be independent risk factors for the incidence of sarcopenia. Purpose This prospective study was performed to elucidate the prevalence and incidence of sarcopenia in community-dwelling older adults who received medical check-ups, and to determine whether FRAX score and fall history predict the incidence of sarcopenia. see more Methods Participants were recruited from a group of individuals who had registered for an annual town-sponsored medical check-up. Study inclusion criteria were aged older than 60 years, living independently, and ability to walk without assistance. Individuals who received nursing care were excluded from the study. A total of 426 residential participants were analyzed. Demographic information, fall history of the previous year, and FRAX score without bone mineral density were assessed. The assessment for sarcopenia was based on the recommendations of the Asian Working Group for Sarcopenia. Results The final sample for the assessment of sarcopenia incidence comprised 258 participants. The mean follow-up time was 2.92 years. The rate of sarcopenia was 1.06 cases per 100 person-years at risk. The Cox multivariate logistic regression model in our analysis was adjusted for age, gender, muscle mass, and covariates and showed that the FRAX score (HR = 1.087, 95% CI 1.014-1.167) and recent history of falls (HR = 5.181, 95% CI 1.002-26.777) were independent risk factors for the incidence of sarcopenia. Conclusion FRAX and history of falling can be a simple screening tool to raise awareness of the prevention of osteoporosis and sarcopenia in clinical settings.Background To compare the diagnostic sensitivity of [18F]fluoroestradiol ([18F]FES) and [18F]fluorodeoxyglucose ([18F]FDG) positron emission tomography/computed tomography (PET/CT) for breast cancer recurrence in patients with estrogen receptor (ER)-positive primary breast cancer. Methods Our database of consecutive patients enrolled in a previous prospective cohort study to assess [18F]FES PET/CT was reviewed to identify eligible patients who had ER-positive primary breast cancer with suspected first recurrence at presentation and who underwent [18F]FDG PET/CT. The sensitivity of qualitative [18F]FES and [18F]FDG PET/CT interpretations was assessed, comparing them with histological diagnoses. Results Of the 46 enrolled patients, 45 were confirmed as having recurrent breast cancer, while one was diagnosed with chronic granulomatous inflammation. Forty (89%) patients were ER-positive, four (9%) were ER-negative, and one (2%) patient did not undergo an ER assay. The sensitivity of [18F]FES PET/CT was 71.1% (32/45, 95% CI, 55.7-83.6), while that of [18F]FDG PET/CT was 80.0% (36/45, 95% CI, 65.4-90.4) with a threshold of positive interpretation, and 93.3% (42/45, 95% CI, 81.7-98.6) when a threshold of equivocal was used. There was no significant difference in sensitivity between [18F]FES and [18F]FDG PET/CT (P = 0.48) with a threshold of positive [18F]FDG uptake, but the sensitivity of [18F]FDG was significantly higher than [18F]FES (P = 0.013) with a threshold of equivocal [18F]FDG uptake. One patient with a benign lesion showed negative [18F]FES but positive [18F]FDG uptake. Conclusions The restaging of patients who had ER-positive primary breast cancer and present with recurrent disease may include [18F]FES PET/CT as an initial test when standard imaging studies are equivocal or suspicious.
