Triple-negative breast cancer (TNBC) is negative for hormone receptors and human epidermal growth factor receptor 2 (HER2). In stage I TNBC, adjuvant therapy or follow-up are performed according to risk factors, but clinical trial data scarce. recent years, it has been reported that HER2-low cases (1+/2+ in situ hybridization negative) have different prognoses than HER2-0 cases. However, the of recurrence factors this population TNBC not yet investigated.Herein, out 174 patients with who...

Abstract Background: Ovarian clear cell carcinoma (OCCC) is a rare subtype of ovarian cancer, with higher incidence in East Asia compared to Western countries and tendency affect younger individuals. OCCC has poor prognosis due its low sensitivity chemotherapy, presenting significant unmet medical need. However, therapeutic development been limited rarity. Recently, advancements antibody-drug conjugates (ADCs) targeting Trophoblastic cell-surface marker (TROP2) have shown promise, but the...

ABSTRACT Background Adenoid cystic carcinoma (ACC) is the second most common and treatment‐resistant salivary gland (SGC). Although platinum‐based therapies are effective, efficacy of eribulin, a microtubule inhibitor with an 18% response rate in Phase II trial involving recurrent/metastatic SGC, patients advanced ACC after platinum therapy remains unclear. Methods We retrospectively analyzed 19 unresectable/metastatic treated between December 2015 January 2023 at National Cancer Center...

Inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal that involves various organs, but has predilection for the urinary bladder in genitourinary tract. Given approximately half of all IMT cases have anaplastic lymphoma kinase (ALK) rearrangements, ALK inhibitor crizotinib suggested as promising treatment unresectable cases. No reports on neoadjuvant therapy locally advanced are available. We report case 17-year-old Japanese boy referred to our institution painful urination and...

Although eribulin is used to treat soft tissue sarcomas (STSs), treatment data for rare subtypes are limited. We conducted a post-marketing surveillance study assess safety and efficacy of in STS patients stratified by subtype.Japanese (n = 256) with advanced or metastatic receiving were monitored status, adverse events, diagnostic imaging, clinical outcomes at 3 months 1 year.

Trabectedin is used as a treatment for advanced-stage soft tissue sarcomas (STSs), particularly liposarcoma and leiomyosarcoma. Aside from its direct effect on tumor cells, trabectedin can affect the immune system in microenvironment. This study aimed to evaluate whether inflammatory biomarkers predict efficacy STSs.

Abstract Introduction: Antibody-drug conjugates (ADCs) targeting trophoblast cell surface antigen 2 (TROP2), such as sacituzumab-govitecan and datopotamab-deruxtecan, have recently been developed. A preclinical study has reported the efficacy of anti-human epidermal growth factor receptor (HER2) TROP2 bispecific ADCs in treating HER2 co-expressing tumors, including HER2-low tumors various solid (Chengzhang Shang et al: AACR 2023). In this study, we aimed to evaluate expression by...
