Incidentally Detected Extramedullary Plasmacytoma of the Gallbladder: A Case Report and Literature Review.

Extramedullary plasmacytoma (EMP) can rarely occur in conjunction with multiple myeloma (MM). EMPs are usually detected in the upper aerodigestive tract (UAD) but can also occur along the digestive tract. However, the involvement of gallbladder is uncommon. Gastrointestinal tract symptoms often lead to the diagnosis of EMP in the gallbladder. An 81-year-old man was referred to our hospital with suspected primary gallbladder carcinoma. He was subsequently operated on, and the pathological findings showed EMP of the gallbladder without MM.

Long-term Outcomes and Prognostic Factors of Stereotactic Body Radiotherapy for Hepatocellular Carcinoma.

BACKGROUND/AIM: This study was conducted to determine the prognosis and risk factors for survival in patients treated with stereotactic body radiotherapy (SBRT) for hepatocellular carcinoma (HCC). PATIENTS AND METHODS: This retrospective study analyzed 73 patients who underwent SBRT for HCC at Nagasaki University Hospital from December 2012 to July 2019 and examined the relationship between baseline information and prognosis. The Kaplan-Meier analysis and log-rank test were used to estimate the survival rate. Cox regression analysis was performed to determine the factors associated with overall survival (OS) after SBRT. RESULTS: The 1- and 2-year local control rates were 98.6% and 89.9%, respectively. Survival rates at 1, 3, and 5 years were 94.5%, 63.9%, and 45.5%, respectively. In the univariate analysis, baseline modified albumin-bilirubin grade (mALBI grade) [2b/3, hazard ratio (HR)=2.762, p=0.001], tumor size (≥2 cm, HR=2.479, p=0.003), and Barcelona Clinic Liver Cancer stage (BCLC) (B/C, HR=3.284, p<0.001) were significantly associated with poor prognosis. In multivariate analysis, baseline mALBI grade (2b/3, HR=2.283, p=0.009) and BCLC stage (B/C, HR=2.330, p=0.013) were significantly associated with poor prognosis. Only three patients (4.1%) developed grade 3 adverse events related to SBRT. CONCLUSION: SBRT is effective and safe in patients with HCC. The baseline mALBI grade is useful for predicting patient prognosis after SBRT. Patients with an mALBI grade of 1/2a are expected to have a better prognosis than patients with an mALBI grade of 2b/3.

Liver Function in Older Patients With Unresectable Hepatocellular Carcinoma After Administration of Lenvatinib.

BACKGROUND: The age of patients with advanced hepatocellular carcinoma (HCC) eligible for molecular-targeted drug treatment is increasing. We assessed liver function after lenvatinib administration according to age in patients with advanced HCC. PATIENTS AND METHODS: In this retrospective, multicenter, observational study, we reviewed the records of patients with HCC who received lenvatinib treatment (March 2018-March 2020). Liver function was measured using the Albumin-Bilirubin Index (ALBI). RESULTS: Of 119 patients, with a median age of 72.0 years, median overall survival was 15.3 months. Overall survival was significantly better in the group which maintained liver function (p=0.02). Older age (≥72 years) was associated with liver-function deterioration within 8 weeks (odds ratio=2.47, 95% confidence interval=1.06-5.75, p=0.035). The ALBI score was significantly higher in the older group at 4 and 8 weeks after lenvatinib administration. CONCLUSION: Lenvatinib administration was more likely to adversely affect liver function in older patients; dose adjustment should be considered in such patients.

The role of pancreatic juice cytology in the diagnosis of pancreatic intraductal papillary mucinous neoplasm.

BACKGROUND AND AIM: pancreatic juice cytology (PJC) is an important predictor of malignant intraductal papillary mucinous neoplasm (IPMN). This study aimed to determine the role of PJC for the prediction of malignant IPMN (intraductal papillary mucinous cancer [IPMC]). METHODS: medical records of IPMN patients who underwent surgery between 2012 and 2016 at the Nagasaki University Hospital were reviewed. Patients who underwent preoperative PJC were classified as high risk stigmata (HRS), worrisome features (WF) and no-criteria, based on imaging criteria. PJC class III or higher was considered as positive and only invasive IPMN was defined as IPMC. PJC was validated in each group with regard to sensitivity, specificity, accuracy with the corresponding 95% confidence intervals (95% CI) and area under receiver operating curve (AUROC) analysis. A p-value of < 0.05 was considered as statistically significant. RESULTS: preoperative pancreatic juice was obtained in 33/52 IPMN patients; only patients with adequate aspirate for cytology (n = 29) were included. In the HRS group (n = 9), 4/6 non-IPMC had a negative PJC and 3/3 IPMC had a positive PJC. In the WF group (n = 17), 9/11 non-IPMC had a negative PJC and 3/6 IPMC had a positive PJC. Adding PJC to imaging results improved the AUROCs of HRS and WF from 0.63 and 0.62 to 0.83 and 0.66, respectively. PJC was negative in all no-criteria cases (n = 3; one IPMC and two non-IPMC). In all 29 patients, PJC sensitivity was 60% (95% CI: 26%-88%), specificity was 79% (95% CI: 54%-94%), accuracy was 72% (95% CI: 63%-89%) and the AUROC was 0.69 (p = 0.03). CONCLUSION: PJC is a statistically significant IPMC predictor that can improve the validity of imaging for IPMC prediction.

Hepatitis B virus reactivation in patients with rheumatoid arthritis: A single-center study.

OBJECTIVES: This study aimed to investigate the frequency of hepatitis B virus (HBV) reactivation in patients with rheumatoid arthritis (RA) and to verify the guidelines relating to HBV reactivation in Japan. METHODS: We retrospectively investigated 1351 RA patients who were treated with antirheumatic drugs at our hospital. RESULTS: Fifty patients (3.7%; 50/1351) were determined to be HBV carriers and 360 patients (26.7%; 360/1351) had resolved infections. HBV reactivation occurred in six cases (1.7%: 6/360) with resolved infections, of whom, two cases (0.6%; 2/360) developed de novo HBV infections. Eleven of the patients who were HBV carriers received a nucleoside analogue (NA) prophylactically. In all of the cases, the HBV-DNA levels became undetectable and the patients' liver function normalized. Sixteen patients, who had lower titers of the HBV surface antigen and undetectable HBV-DNA levels, did not show HBV reactivation in the absence of NA therapy. CONCLUSIONS: The results from this study suggest that HBV reactivation might not be so frequent among RA patients, and that reliable indicators for prescribing a NA should be clarified for RA patients.
