Background and Aim Reliable predictors for hepatocellular carcinoma (HCC) are urgently needed. The psoas muscle index (PMI) is a simple and rapid method for evaluating muscle atrophy. Furthermore, the neutrophil/lymphocyte ratio (NLR) is a prognostic factor that is easy to calculate in everyday clinical practice. We aimed to investigate the value of the PMI and NLR as prognostic factors for patients receiving nonsurgical HCC therapy, hepatic arterial infusion chemotherapy (HAIC), transcatheter arterial chemoembolization (TACE), or molecular targeted drugs such as sorafenib (SOR) and lenvatinib (LEN). Methods We enrolled 87 patients with HCC who were treated with HAIC, TACE, SOR, or LEN. The primary endpoint was overall survival (OS) with variable PMI or NLR status. For Barcelona Clinic Liver Cancer (BCLC)‐B patients, useful prognostic factors were examined by comparing the OS between stratified groups. Prognostic factors including PMI and NLR were evaluated by univariate and multivariate analysis. Results Analysis of HAIC or TACE (HAIC/TACE) and SOR or LEN (SOR/LEN) patients showed significant differences in OS between low and high PMI. In patients treated with TACE, there was a significant difference in OS between low and high NLR. For BCLC‐B and low PMI, the prognosis was significantly worse for SOR/LEN than for TACE, although there was no difference for high PMI, suggesting that PMI may be useful for treatment selection. In addition, the prognostic formula composed of PMI, NLR, and up‐to‐seven criteria developed in the present study may be useful. Conclusion PMI and NLR are considered to be independent prognostic factors for HCC., Psoas muscle index (PMI) was an independent predictor for all nonsurgical hepatocellular carcinoma (HCC) treatments, and neutrophil/lymphocyte ratio (NLR) was a significant predictor for transcatheter arterial chemoembolization (TACE). In Barcelona Clinic Liver Cancer (BCLC)‐B, if the PMI was low, sorafenib (SOR) or lenvatinib (LEN) was associated with a poor prognosis, and thus PMI may be useful for guiding the choice of treatment. The formula combining PMI and NLR (= 0.555 × [up‐to‐seven out:1, in:0] + 0.161 × NLR − 0.191 × PMI) appears to be useful for predicting the prognosis of HCC.

A 50-year-old woman with adrenal Cushing’s syndrome and chronic hepatitis C developed an acute exacerbation of chronic hepatitis C before adrenectomy. After administration of Glecaprevir/Pibrentasvir was started, her transaminase levels normalized promptly and a rapid virological response also was achieved. Then laparoscopic left adrenectomy was performed safely.

Our pathological study of a case of poorly differentiated lymphocyte‐rich hepatocellular carcinoma suggested that immune checkpoint inhibitor may be an effective therapy. The histological type is an important factor in determining treatment choices., We presented a rare case of poorly differentiated lymphocyte‐rich hepatocellular carcinoma. In this case, multiple small foci of programmed cell death ligand 1 positive inflammatory cell clusters were founded around glypican 3‐positive tumor cells.

Non-alcoholic steatohepatitis (NASH)-related HCC is associated with oxidative stress. However, the mechanisms underlying the development of NASH-related HCC is unclear. MUTYH is one of the enzymes that is involved in repair of oxidative DNA damage. The aim of this study was to investigate the association between MUTYH and NASH-related hepatocarcinogenesis. MUTYH wild-type (Mutyh+/+), heterozygous (Mutyh+/−), and MUTYH-null (Mutyh−/−) mice were fed a high-fat high-cholesterol (HFHC) diet or HFHC + high iron diet (20 mice per group) for 9 months. Five of 20 Mutyh−/− mice fed an HFHC + high iron diet developed liver tumors, and they developed more liver tumors than other groups (especially vs. Mutyh+/+ fed an HFHC diet, P = 0.0168). Immunohistochemical analysis revealed significantly higher accumulation of oxidative stress markers in mice fed an HFHC + high iron diet. The gene expression profiles in the non-tumorous hepatic tissues were compared between wild-type mice that developed no liver tumors and MUTYH-null mice that developed liver tumors. Gene Set Enrichment Analysis identified the involvement of the Wnt/β-catenin signaling pathway and increased expression of c-Myc in MUTYH-null liver. These findings suggest that MUTYH deficiency is associated with hepatocarcinogenesis in patients with NASH with hepatic iron accumulation.

The clinical benefit of conversion surgery (CS) for unresectable gastric cancer (GC), whereby unresectable GC responds to chemotherapy and subsequently receives curative-intent surgery, remains unclear. Here, we aimed to clarify the clinical value of CS. In this retrospective cohort study, we analyzed 175 unresectable GC, who received triple combined chemotherapy between 2004 and 2019. We divided patients into two groups: those who underwent CS and those receiving chemotherapy only (CS and C groups, respectively). Propensity score matching was used to minimize confounding bias. Of 175 cases, 61 (34.9%) underwent CS. R0 resection was obtained in 85.2%. After matching, 44 pairs were selected; there were no significant differences in baseline covariants. Group CS had a significantly better median overall survival (OS) (18.8 vs. 46.0 months, p

Muscle cramps are side effects commonly associated with tyrosine kinase inhibitor (TKI) treatment. Patients suffering from muscle cramps are treated with various medications such as calcium, magnesium and vitamin supplements, but these therapies are often ineffective. We report two patients with chronic myelogenous leukemia who developed muscle cramps caused by TKI. These patients were treated successfully with levocarnitine. Both of our cases revealed the beneficial effects of levocarnitine treatment on TKI-induced muscle cramps.

An 86-year-old man presented with enlarged left submandibular, left inguinal, and superficial femoral lymph nodes. He was diagnosed with Langerhans cell sarcoma (LCS) on the basis of the histopathological findings of the left inguinal lymph node biopsy. In addition, laboratory examinations revealed normocytic normochromic anemia, and bone marrow aspiration and biopsy led to a diagnosis of idiopathic cytopenia of undetermined significance (ICUS). Because of the patient's age, he was administered a regimen of cyclophosphamide, pirarubicin, vincristine, and prednisolone (THP-COP), and achieved a partial response after six courses. However, he developed acute myeloid leukemia (AML) 11 months after completion of the THP-COP therapy, and received only supportive care until his death. LCS is an extremely rare and aggressive dendritic cell neoplasm. To the best of our knowledge, only 67 cases have been reported in the literature. There are case reports describing the concurrence of hematological malignancies. Herein, we report the first documented development of LCS in a patient with ICUS who progressed to AML, and summarize the published data on the epidemiology of and therapeutic options for LCS.

Double- and triple-hit lymphomas (DHL/THL), high-grade B-cell lymphomas with an extremely poor prognosis, are defined by a chromosomal breakpoint affecting the MYC/8q24 locus in combination with another recurrent breakpoint. The successful use of dose-adjusted (DA) EPOCH-R in patients with MYC-positive lymphoma and Burkitt lymphoma (BL) was recently reported. A 74-year-old man with acute renal dysfunction and hyperkalemia was transferred to our emergency center by ambulance. PET-CT revealed a left renal hilar mass enveloping the abdominal para-aortic domain and bladder and hydronephrosis. High (18)F-FDG uptake revealed lymph node, peritoneum, and multiple bone metastases. Analysis of the bone marrow aspirate revealed abnormal lymphoid cells with deeply basophilic cytoplasm and numerous vacuoles resembling Burkitt cells. Chromosomal analysis revealed a complex chromosomal karyotype, including t(14;18)(q32;q21), and FISH analysis confirmed split BCL2, BCL6, and MYC signals. Bone marrow biopsy revealed diffusely infiltrating large abnormal lymphoid cells with a CD10⁺, CD20⁺, BCL2⁺, BCL6⁺, c-MYC⁺ and MUM1(-) immunophenotype. B-cell lymphoma, unclassifiable with features intermediate between diffuse large B-cell lymphoma and BL, was diagnosed. The patient achieved a partial response after eight courses of DA-EPOCH-R chemotherapy. Our experience suggests that DA-EPOCH-R may be an effective treatment for DHL/THL.

354 Background: The significance of conversion therapy (CT), whereby patients (pts) with unresectable disease respond to chemotherapy and subsequently receive surgery with curative intent (adjuvant surgery: AS), has been specifically established for metastatic colorectal cancer. However, such a strategy for advanced or recurrent gastric cancer (AGC) remains controversial. This study aims to clarify the clinical significance of CT for AGC. Methods: In this retrospective multi-institution observational study, we analyzed 168 AGC pts who received chemotherapy consisting of docetaxel, cisplatin or oxaliplatin, and S-1 ± trastuzumab between 2003 and 2019. We divided pts into two groups: those who underwent CT (group CT) or chemotherapy only (group C). Propensity score analysis with 1:1 matching minimized confounding bias when comparing efficacy and safety between groups. Results: A tumor response to chemotherapy was observed in 82.4% of all cases, while 34.5% (58/168) underwent AS. Fifty-one of the 58 pts underwent an R0 resection, and 79.3% were deemed histological responders. After matching, 44 pairs of C and CT pts were selected; significant differences in baseline characteristics were not observed. Incidences of adverse events during chemotherapy were similar between groups, with neutropenia and febrile neutropenia as common grade 3–4 events. Compared with group C, group CT had a significantly better median overall survival (OS) (15.5 vs. 46.0 months; hazard ratio [HR] 0.32; 95% confidence interval [CI] 0.18–0.58; p < .001), and a prolonged progression-free survival (6.5 vs.22.6 months; HR 0.33; 95% CI 0.19–0.56; p < .001). Subgroup analysis of OS showed a favorable trend for CT for almost all parameters. In a multivariate analysis, ECOG performance status (HR 0.10; 95% CI 0.03–0.31) and AS (HR 0.20; 95% CI 0.10–0.40) correlated with favorable OS. In the CT group, pathological response was an independent prognostic factor (HR 0.16; 95% CI 0.06–0.39). Conclusions: CT was associated with better outcomes in AGC pts, even after baseline adjustment. Our data warrants further large-scale studies to establish a conversion therapeutic strategy.
