A unique case of high-grade myofibroblastic sarcoma initially presenting with oral symptoms.

High-grade myofibroblastic sarcoma is a rare mesenchymal tumor with a high recurrence and metastatic rate. Few cases of high-grade myofibroblastic sarcomas have been reported. Herein, we report a rare case of undifferentiated, high-grade myofibroblastic sarcoma with an unclear primary site, initially presenting with oral symptoms.

Clinical Impact of Primary Tumor Location in Metastatic Colorectal Cancer Patients Under Later-Line Regorafenib or Trifluridine/Tipiracil Treatment.

Background: Primary tumor location (PTL) is an important prognostic and predictive factor in the first-line treatment of metastatic colorectal cancer (mCRC). Although regorafenib (REG) and trifluridine/tipiracil (FTD/TPI) have been introduced recently, the clinical impact of PTL in these treatments is not well understood.

Materials And Methods: We retrospectively evaluated patients with mCRC who were registered in a multicenter observational study (the REGOTAS study).

Clinical Outcomes Following Trifluridine/Tipiracil Treatment for Patients With Metastatic Colorectal Cancer Ineligible for Regorafenib Treatment.

Background/aim: In later-line treatment of metastatic colorectal cancer (mCRC), trifluridine/tipiracil is often selected because regorafenib is difficult to use in patients with comorbidities such as thrombosis, hemorrhage, or cardiac events. However, the safety and efficacy of trifluridine/tipiracil in these patients is not clear.

Patients And Methods: The clinical outcomes of trifluridine/tipiracil were retrospectively investigated in patients who were ineligible for regorafenib because of comorbidities.

Survival Benefit of Crossover Administration of Regorafenib and Trifluridine/Tipiracil Hydrochloride for Patients With Metastatic Colorectal Cancer: Exploratory Analysis of a Japanese Society for Cancer of the Colon and Rectum Multicenter Observational Study (REGOTAS).

The survival benefits of regorafenib (REG) and trifluridine/tipiracil hydrochloride (TFTD) have been demonstrated in chemorefractory patients with metastatic colorectal cancer (mCRC). However, the effects of crossover administration of REG and TFTD on patient survival remain unclear. The present study evaluated the association between exposure to REG and TFTD and overall survival (OS) in patients with mCRC using data from the REGOTAS study.

Regorafenib vs trifluridine/tipiracil for metastatic colorectal cancer refractory to standard chemotherapies: A multicenter retrospective comparison study in Japan.

Regorafenib (REG) and trifluridine/tipiracil (FTD/TPI) showed survival benefits in metastatic colorectal cancer patients previously treated with standard chemotherapies; therefore, we compared the efficacy and safety of these two treatments. Patients with metastatic colorectal cancer treated with REG or FTD/TPI as a salvage-line therapy from May 2014 to December 2017 were included. We retrospectively analyzed long-term survival, safety, and clinical outcomes.

Acute Liver Failure with Diffuse Liver Metastasis from Breast Cancer, Not Detected by Computed Tomography: 2 Case Reports.

Diffuse liver metastasis is a rare pattern of liver metastasis that is associated with hepatic failure and poor prognosis. We experienced 2 cases of acute liver failure due to diffuse metastasis that could not be detected using computed tomography. In , it was difficult to differentiate diffuse metastasis from alcoholic hepatitis.

Effectiveness of Crizotinib for Inflammatory Myofibroblastic Tumor with ALK mutation.

Inflammatory myofibroblastic tumor (IMT), a rare sarcoma, is primarily treated via resection of the mass. However, in cases of recurrence or unresectable tumors, no standard care exists. While crizotinib, an anaplastic lymphoma kinase (ALK) inhibitor, is only approved for non-small-cell lung cancer with ALK mutation, it is reportedly effective for other malignant tumors with ALK mutation.

Neutrophil-to-lymphocyte ratio as a predictive or prognostic factor for gastric cancer treated with nivolumab: a multicenter retrospective study.

Introduction: The neutrophil-to-lymphocyte ratio (NLR) is effective as a predictive factor for lung cancer treated with nivolumab. The objective of this study was to determine the effectiveness of NLR for patients with advanced gastric cancer (AGC) treated with nivolumab.

Methods: This was a multicenter, retrospective study of patients with AGC treated with nivolumab from June 2017 to December 2017.

Evaluation of health-related quality of life via the Computer-Based Health Evaluation System (CHES) for Japanese metastatic breast cancer patients: a single-center pilot study.

Background: The main purposes of metastatic breast cancer (MBC) treatment are to prolong survival and maintain health-related quality of life (HRQOL). Compliance with the HRQOL assessment can be poor, particularly among patients who receive long-term treatment. One possible solution to overcoming this problem is to engage in real-time home monitoring by having patients report outcomes on their personal electronic devices.

Phase Ib study of irinotecan and ramucirumab for advanced gastric cancer previously treated with fluoropyrimidine with/without platinum and taxane.

Purpose: Optimal salvage chemotherapy for patients with treated advanced/metastatic gastric cancer (AGC) is unknown. Irinotecan is commonly used in Japan. Ramucirumab, a human IgG-1 monoclonal antibody targeting the extracellular domain of VEGF receptor 2, is the first molecularly targeted agent proven to be effective in second-line therapy for AGC in combination with chemotherapy.

Prevalence and risk factors of hepatitis B virus reactivation in patients with solid tumors with resolved HBV infection.

Background: Reports of hepatitis B virus (HBV) reactivation in solid tumors are very limited, and their frequencies and risk factors were previously unknown.

Aim: To evaluate the prevalence and risk factors of HBV reactivation in patients with solid tumors with resolved HBV infection.

Methods: All 1088 patients with solid tumors were assessed for eligibility; 251 patients had resolved HBV infection (negative for HBs antigen and positive for anti-HBc antibody and/or positive for anti-HBs antibody), and HBV-DNA was assessed for 243 of these patients in whom we analyzed the prevalence of HBV reactivation.

Hyperprogressive Disease in the Irradiation Field after a Single Dose of Nivolumab for Gastric Cancer: A Case Report.

Following the ATTRACTION-2 study, nivolumab was approved for advanced gastric cancer in Japan. However, pseudoprogression and hyperprogressive disease have been reported in patients treated with immune checkpoint inhibitors. We report a patient with gastric cancer who received nivolumab after radiotherapy only to experience rapid progression within the irradiation field after the first immunotherapy session.

Oxaliplatin-Induced Hyperammonemic Encephalopathy in a Patient with Metastatic Pancreatic Cancer: A Case Report.

Oxaliplatin-based chemotherapy is widely used to treat advanced cancer. Oxaliplatin-induced hyperammonemic encephalopathy is rarely reported. Here, we report a case of oxaliplatin-induced hyperammonemic encephalopathy occurring after gemcitabine plus oxaliplatin (GEMOX) chemotherapy in a patient with pancreatic cancer.

Multicenter phase II study of trastuzumab plus S-1 alone in elderly patients with HER2-positive advanced gastric cancer (JACCRO GC-06).

Background: S-1 plus cisplatin is a standard regimen for advanced gastric cancer (AGC) in Asia. The ToGA trial established a fluoropyrimidine plus cisplatin and trastuzumab as a standard treatment for human epidermal growth factor receptor 2 (HER2)-positive AGC. In the HERBIS-1 trial, trastuzumab combined with S-1 plus cisplatin showed promising antitumor activity in patients with HER2-positive AGC.

First-line chemotherapy with capecitabine/oxaliplatin for advanced gastric cancer: A phase I study.

Combination chemotherapy with capecitabine and oxaliplatin for gastric cancer (G-XELOX) is considered as a potentially promising regimen. However, the use of the G-XELOX regimen in Japanese patients has not been investigated to date, and recommended doses of G-XELOX for Japanese patients with metastatic gastric cancer have not been established. The aim of the present study was to determine the maximum tolerated dose (MTD) and recommended dose (RD) for systemic chemotherapy with G-XELOX for metastatic gastric cancer.
