Lesion size, elevated morphology, and non or closed-type atrophy are predictive factors for gastric adenocarcinoma of the fundic gland type rather than oxyntic gland adenoma.

Background: An oxyntic gland neoplasm confined to the mucosal layer (T1a) is classified as an oxyntic gland adenoma, whereas that with submucosal invasion (T1b) is defined as gastric adenocarcinoma of the fundic gland type (GA-FG).

Methods: To reveal the differences in clinical features between them, we retrospectively investigated 136 patients with 150 oxyntic gland adenoma and GA-FG lesions.

Results: The univariate analysis revealed that the mean size (GA-FG oxyntic gland adenoma, 7.

Genomic landscape and its prognostic significance in stage III colorectal cancer: JCOG1506A1, an ancillary of JCOG0910.

Large-scale genomic sequencing of colorectal cancers has been reported mainly for Western populations. Differences by stage and ethnicity in the genomic landscape and their prognostic impact remain poorly understood. We investigated 534 Japanese stage III colorectal cancer samples from the Phase III trial, JCOG0910.

A Phase II Trial of Trifluridine/Tipiracil in Combination with Cetuximab Rechallenge in Patients with RAS Wild-Type mCRC Refractory to Prior Anti-EGFR Antibodies: WJOG8916G Trial.

Background: Trifluridine/tipiracil (FTD/TPI) improved the overall survival in patients with metastatic colorectal cancer (mCRC) who had previously received standard chemotherapies; however, the clinical outcomes remain poor.

Objective: A multicenter phase II study aimed to assess the efficacy and safety of FTD/TPI plus cetuximab rechallenge.

Patients And Methods: Patients with histologically confirmed RAS wild-type mCRC refractory to prior anti-epidermal growth factor receptor (anti-EGFR) antibody were enrolled and treated with FTD/TPI (35 mg/m twice daily on days 1-5 and 8-12) plus cetuximab (initially 400 mg/m, followed by weekly 250 mg/m) every 4 weeks.

A retrospective study on the incidence, management and risk factors of skin rash in patients with advanced prostate cancer in Japan.

Background: Worldwide, prostate cancer (PC) is the second most diagnosed cancer and the fifth leading cause of cancer death in men. Hormonal therapies, commonly used for PC, are associated with a range of treatment-emergent adverse events (TEAEs). The population from Japan seems to be at higher risk of developing TEAEs of skin rash compared to the overall global population.

Venous thromboembolism in Japanese patients with breast cancer: subgroup analysis of the Cancer-VTE Registry.

Background: This subgroup analysis of the Cancer-VTE Registry, a nationwide, large-scale, multicenter observational study with a 1-year follow-up, assessed real-world data on venous thromboembolism (VTE) among Japanese patients with breast cancer.

Methods: Patients with stage II-IV pretreatment breast cancer screened for VTE at enrollment were included. During the 1-year follow-up period, incidences of VTE, bleeding, and all-cause death, and background factors associated with VTE risk were examined.

Prognostic assessment of patients who receive radiotherapy for bone metastases from breast cancer.

For prognostic assessment in women who receive radiotherapy (RT) for bone metastases (BMs) from breast cancer (BC), prognostic factors specific for BMs from BC were investigated in the present study. The prognostic assessment was performed by retrospectively reviewing 143 women who received first-time RT for BMs from BC between January 2007 and June 2018. The median follow-up time and median overall survival (OS) time from the first-time RT for BMs were 22 and 18 months, respectively.

Clinical Guidelines for Diagnosis and Management of Peutz-Jeghers Syndrome in Children and Adults.

Background: Peutz-Jeghers syndrome (PJS) is a rare disease characterized by the presence of hamartomatous polyposis throughout the gastrointestinal tract, except for the esophagus, along with characteristic mucocutaneous pigmentation. It is caused by germline pathogenic variants of the STK11 gene, which exhibit an autosomal dominant mode of inheritance. Some patients with PJS develop gastrointestinal lesions in childhood and require continuous medical care until adulthood and sometimes have serious complications that significantly reduce their quality of life.

Long-term outcomes of patients with primary intestinal follicular lymphoma managed with watch-and-wait strategy.

Patients with primary intestinal follicular lymphoma are often followed-up without a specific treatment, and this approach is called the "watch-and-wait approach." However, the long-term outcomes of this patient group have not been sufficiently investigated. We enrolled patients with primary intestinal follicular lymphoma who were diagnosed before 2016 and managed with the watch-and-wait approach in 20 institutions.

Patient-reported outcomes after robot-assisted radical prostatectomy and institutional learning curve for functional outcomes.

Purpose: The study was performed to examine patient-reported outcomes (PROs) in the 1 year after surgery and the institutional learning curve after the introduction of robot-assisted radical prostatectomy (RARP).

Materials And Methods: The subjects were 320 consecutive patients who underwent RARP from 2014 to 2018. These cases were divided into three groups treated in the early, middle, and late periods, with about 100 cases in each.

Poor Treatment Outcomes of Locally Advanced Cervical Adenocarcinoma of Human Papilloma Virus Independent Type, Represented by Gastric Type Adenocarcinoma: A Multi-Center Retrospective Study (Sankai Gynecology Study Group).

The revised World Health Organization classification of cervical cancer divides adenocarcinomas into human papillomavirus-associated (HPVa) and -independent (HPVi) types; the HPVi type is represented by the gastric type. The treatment outcomes of locally advanced adenocarcinoma (LaAC), based on this classification, are understudied. We investigated the outcomes of patients with HPVa and HPVi LaACs.

Trastuzumab Deruxtecan for Human Epidermal Growth Factor Receptor 2-Expressing Advanced or Recurrent Uterine Carcinosarcoma (NCCH1615): The STATICE Trial.

Purpose: To investigate the efficacy and safety of trastuzumab deruxtecan, an antibody-drug conjugate targeting human epidermal growth factor receptor 2 (HER2) with a topoisomerase I inhibitor payload, in patients with uterine carcinosarcoma (UCS) expressing HER2.

Patients And Methods: Patients with recurrent UCS with HER2 immunohistochemistry scores ≥1+ previously treated with chemotherapy were included. Patients were assigned to the HER2-high (immunohistochemistry score ≥2+; n = 22) or low (immunohistochemistry score of 1+; n = 10) groups for primary and exploratory analyses, respectively.

Impact of palliative radiotherapy with or without lung irradiation in patients with interstitial lung disease.

Background And Purpose: Acute exacerbations or acute lung injury, including radiation pneumonitis (AE-ALI/RP) of interstitial lung disease (ILD), has a fatal prognosis. We evaluated the risk of palliative-intent radiotherapy (RT), with or without lung irradiation, for AE-ALI/RP of ILD.

Materials And Methods: The data of patients with ILD who received palliative-intent RT between January 2011 and January 2022 were retrospectively reviewed.

Radical prostatectomy trends between 2010 and 2020 in Ehime, Japan, identified using data from the Medical Investigation Cancer Network (MICAN) study.

Objectives: The use of radical prostatectomy is increasing with the rising incidence of prostate cancer. We assessed the surgical trends related to radical prostatectomy using data from a multi-center, retrospective cohort study, the MICAN (Medical Investigation Cancer Network) study, which was conducted in all the urology-related medical facilities in Ehime Prefecture, Japan.

Methods: We compared data from the MICAN study with prostate biopsy registry data collected in Ehime between 2010 and 2020 and recorded the surgical trends.

Multicentre real-world data of ramucirumab plus docetaxel after combined platinum-based chemotherapy with programmed death-1 blockade in advanced non-small cell lung cancer: NEJ051 (REACTIVE study).

Background: Ramucirumab plus docetaxel (RD) is a promising treatment for previously treated advanced non-small cell lung cancer (NSCLC). However, its clinical significance after platinum-based chemotherapy plus programmed death-1 (PD-1) blockade remains unclear.

Research Question: What is the clinical significance of RD as a second-line treatment after the failure of chemo-immunotherapy in NSCLC?

Study Design And Methods: In this multicentre retrospective study, 288 patients with advanced NSCLC who received RDas second-line therapy after platinum-based chemotherapy plus PD-1 blockade, at 62 Japanese institutions from January 2017 to August 2020, were included.

Fosnetupitant for the Prevention of Chemotherapy-Induced Nausea and Vomiting: A Short Review and Clinical Perspective.

Chemotherapy-induced nausea and vomiting (CINV) is often ranked by patients as one of the most distressing and feared consequences of chemotherapy. The novel neurokinin-1 (NK) receptor antagonist fosnetupitant, a phosphorylated prodrug formulation of netupitant, was approved in Japan in 2022. Fosnetupitant is one of the standard treatments for the prevention of CINV in patients who are receiving highly (any treatment where CINV occurs in more than 90% of patients) or moderately (where CINV occurs in 30-90% of patients) emetogenic chemotherapies.

Trifluridine/tipiracil+bevacizumab (BEV) vs. fluoropyrimidine-irinotecan+BEV as second-line therapy for metastatic colorectal cancer: a randomised noninferiority trial.

Background: This open-label, multicentre, phase II/III trial assessed the noninferiority of trifluridine/tipiracil (FTD/TPI) plus bevacizumab vs. fluoropyrimidine and irinotecan plus bevacizumab (control) as second-line treatment for metastatic colorectal cancer (mCRC).

Methods: Patients were randomised (1:1) to receive FTD/TPI (35 mg/m twice daily, days 1-5 and days 8-12, 28-day cycle) plus bevacizumab (5 mg/kg, days 1 and 15) or control.

Vertebral body collapse after radiotherapy for spinal metastases.

Spinal metastases are common in patients with advanced stages of cancer and frequently cause vertebral body collapse (VBC). Although conventional radiotherapy (RT) is used for spinal metastases, the rates of occurrence of new VBC and progression of VBC at RT initiation have not been fully investigated. The present retrospective study assessed VBC and its associated risk factors after RT over time and evaluated new VBC and progression of VBC in patients who presented with VBC at RT initiation.
