A 77-year-old-woman, whose chief complaint was anemia, was referred to our hospital and diagnosed with advanced gastric cancer with liver metastasis and lymph node metastasis.Gastrointestinal endoscopy showed a tumor on the lesser curvature of the gastric corpus.Histologically, biopsy specimens indicated adenocarcinoma with genetic amplification of human epidermal growth factor receptor type 2.Computed tomography and magnetic resonance imaging showed lymph node metastasis and liver metastasis.The patient received a total gastrectomy and a partial liver resection after combination chemotherapy consisting of capecitabine, cisplatin, and trastuzumab.Histopathological examination of a resected specimen showed a minute residual cancer nest at the subserosa of the stomach and lymph node metastasis, but no liver metastasis. This combined modality therapy can be considered an effective treatment for gastric cancer with liver metastasis, and we hope that it will be established as a standard therapy.

Colorectal cancer (CRC) remains a leading cause of cancer death due to metastatic spread. LIN28B is overexpressed in 30% of CRCs and promotes metastasis, yet its mechanisms remain unclear. In this study, we genetically modified CRC cell lines to overexpress LIN28B, resulting in enhanced PI3K/AKT pathway activation and liver metastasis in mice.

Background: Colorectal cancer (CRC) exhibits a high incidence globally, with the liver being the most common site of distant metastasis. At the time of diagnosis, 20-30% of CRC patients already present with liver metastases. Colorectal liver metastasis (CRLM) is a major cause of mortality among CRC patients.

Metastasis and recurrence are the primary obstacles to long-term survival in colorectal cancer (CRC) patients. In this study, we employed single-cell RNA sequencing (scRNA-seq) to comprehensively delineate the transcriptomic landscape of primary and liver metastatic CRCs, and revealed novel cellular crosstalk between cancer cell subpopulation and myofibroblastic CAFs (myCAFs) at single-cell resolution. We identified a cancer cell subpopulation termed stem/transient amplifying-like (stem/TA-like) cells, which expressed genes associated with stem cell-like characteristics and metastatic potential.

Introduction: Randomized phase III trials showed that using trifluridine/tipiracil (FTD/TPI) in patients with pre-treated metastatic colorectal cancer (mCRC) conferred survival benefit versus placebo. Here, we investigated the effectiveness and safety of FTD/TPI and sought to identify prognostic factors among the mCRC population in Hong Kong.
Methods: A non-interventional, retrospective, multicenter cohort study enrolled patients with mCRC who received FTD/TPI in seven public hospitals in Hong Kong between 2016 and 2020.

Aberrant expression of grainyhead-like transcription factor 3 (GRHL3) has been extensively reported in the development and progression of several squamous cell carcinomas, such as cutaneous, head and neck, and esophageal squamous cell carcinoma. However, the clinical significance and biological roles of GRHL3 in lung squamous cell (LUSC) carcinoma are largely unclear. Herein, we report that GRHL3 was significantly upregulated in lung squamous epithelium of LUSC tissues, bronchiole, and bronchus.
