Background: The commonest sites of extrahepatic metastases from hepatocellular carcinoma (HCC) are the lungs, bones, adrenal glands, and regional lymph nodes. Hematogenous metastasis to the gastrointestinal (GI) tract is a rare condition in patients with HCC, and the prognosis is usually poor. We report, herein, an extremely rare case of a patient with intussusception due to hematogenous metastasis of HCC to the ileum and his long-term survival with multidisciplinary therapy.
Case Summary: The patient was a 71-year-old man with a history of chronic hepatitis B, who had undergone three surgeries for HCC. He was treated with sorafenib for peritoneal metastases of HCC. He was admitted to our hospital with chief complaints of abdominal pain and vomiting. Abdominal contrast-enhanced computed tomography imaging revealed a small intestinal tumor, presenting with intussusception and small bowel obstruction. Conservative treatment was started, but due to repeated exacerbation of symptoms, surgery was planned on the 28 d of hospitalization. Partial ileal resection without reducing the intussusception and end-to-end anastomosis was performed. On histological examination, tumor cells were not observed on the serosal surface, but intravascular invasion of tumor cells was seen. Immunohistochemistry was positive for immunohistochemical markers, and a diagnosis of hematogenous metastasis of HCC to the ileum was made. He remains alive 82 mo after the first surgery.
Conclusion: Prognosis of HCC patients with GI tract metastasis is usually poor, but in some cases, multidisciplinary therapy may prolong survival.

The role of the gut microbiome in the development and progression of liver cancer has long been recognized. However, the presence of microbes in tumors that were previously considered sterile has only recently been discovered. The intratumor microbiome in liver cancer likely originates from various sources, including the gut, hematogenous spread from other mucosal locations, adjacent non-cancerous tissues, and co-metastasis with the tumor cells.

Background: The liver, as the main target organ for hematogenous metastasis of colorectal cancer, early and accurate prediction of liver metastasis is crucial for the diagnosis and treatment of patients. Herein, this study aims to investigate the application value of a combined machine learning (ML) based model based on the multiparameter magnetic resonance imaging for prediction of rectal metachronous liver metastasis (MLM).
Aim: To investigate the efficacy of radiomics based on multiparametric magnetic resonance imaging images of preoperative first diagnosed rectal cancer in predicting MLM from rectal cancer.

Background: Cutaneous melanoma is the leading cause of death from cutaneous malignancy and tends to metastasize lymphatically and hematogenously to the lung, liver, brain, and bone; it is a rare source of metastatic disease to the eye. Herein we provide a case report of cutaneous melanoma metastatic to the ciliary body and choroid involving clinical examination, slit lamp photography, and B-scan ultrasonography.
Result: A 55-year-old female with known metastatic cutaneous melanoma presented with pain, a large ciliochoroidal mass, visual decline, and diffuse intraocular inflammation.
Platelets and megakaryocytes in cancer.

Platelets have important roles in hemostasis but also actively participate in cancer metastasis and inflammatory processes. They are produced by large precursor cells, the megakaryocytes, residing mainly in the bone marrow. Clinically, elevated platelet counts and/or increased platelet-to-lymphocyte ratio are being explored as biomarkers of metastatic disease and to predict survival or response to therapy in certain cancers.

Small cell lung carcinoma metastatic to the stomach, whether synchronous or metachronous, is a rare phenomenon accounting for < 0.5% of lung cancers. Hence it can be overlooked by clinicians resulting in delayed diagnosis.
