Intrahepatic cholangiocarcinoma (ICC) is the second most common primary liver tumor and remains a fatal malignancy in most patients. Only 20% to 30% of patients can be treated with potentially curative surgical resection. Local therapies such as radioembolization and hepatic arterial perfusion may be a more effective treatment strategy.

Objectives: Although curative resection for synchronous peritoneal carcinomatosis has been reported to improve prognosis, cases with positive intraoperative lavage cytology have not been reported. In this study, we investigated the prognostic value of potentially curative resection based on colorectal cancer and lavage cytology positivity in patients with synchronous peritoneal carcinomatosis.
Methods: We retrospectively evaluated 72 patients who underwent intraoperative lavage cytology and one-stage potentially curative resection of primary and metastatic lesions (lavage cytology-positive, n = 21; lavage cytology-negative, n = 51) between July 2004 and December 2019.

Objectives: Mismatch repair (MMR)-deficient (dMMR) colorectal cancer (CRC) have been largely categorized into three subtypes: methylated, Lynch syndrome (LS)-associated, and Lynch-like syndrome (LLS)-associated. No studies have examined the prevalence and subtypes of synchronously diagnosed dMMR CRCs in detail. Therefore, this study aimed to examine the frequency and molecular characteristics of the dMMR status among multiple synchronous CRCs to clarify the clinical significance of identifying patients with such tumors.

Objectives: To clarify the risk factors affecting prognosis after primary tumor resection (PTR) in patients with metastatic colorectal cancer with synchronous peritoneal metastasis (mCRC-SPM).
Methods: Patients were enrolled prospectively in the JSCCR project "Grading of Peritoneal Seeding in Colorectal Cancer." Factors that may influence overall survival-age, sex, location of the primary tumor, lymph node metastasis, presence of liver metastasis, degree of peritoneal metastasis, peritoneal cancer index (PCI), cancer cure, and postoperative chemotherapy-in the PTR group were examined using multivariate analysis.

Background: The efficacy of local control for pancreatic cancer liver metastases (PCLM), including surgical treatment, remains controversial, with no consensus on the management and clinical significance of disappearing liver metastases (DLMs). This study aimed to evaluate the clinical implications of DLMs in treating PCLM after multi-agent chemotherapy, utilizing contrast-enhanced imaging modalities.
Methods: A retrospective analysis was conducted on patients who underwent curative resection for pancreatic cancer with synchronous or metachronous liver metastases between 2014 and 2023.
