Cutaneous metastases from colorectal cancers are rare and are usually present on the abdominal wall or previous surgical incision sites. Remote cutaneous lesions have been reported, however, often occur in the setting of widespread metastatic disease including other visceral secondaries. We present a case of lower extremity cutaneous metastases as the first sign of metastatic disease in a patient with adenocarcinoma of the colon. This case illustrates that new skin lesions may be the initial presentation of metastatic disease in a patient with a history of cancer.

Purposes: This study aimed to clarify the clinical outcomes of Bacillus Calmette-Guérin (BCG) treatment in patients with urothelial carcinoma (UC) of the prostatic urethra.
Methods: Between August 2003 and January 2023, 428 patients with non-muscle-invasive UC received BCG treatment (Tokyo strain, 80 mg, ≥ 5 times) in our hospital; 39 had UC of the prostatic urethra. We evaluated the cumulative incidence of intravesical recurrence, progression (muscle-invasive bladder cancer [MIBC] or metastasis), and subsequent radical cystectomy after BCG treatment in patients with UC of the prostatic urethra.

Although sialoblastoma (SBL) is defined as a low-grade malignant salivary gland anlage neoplasm in the 2022 World Health Organization (WHO) Classification of Head and Neck Tumors, its histology, genetics, and behavior remain controversial due to the rarity of the tumor. Here, we performed the first comprehensive clinical, histologic, and molecular analyses of 8 SBLs to better understand their pathogenesis and prognosis. This cohort consisted of 5 boys and 3 girls, with ages ranging from birth to 9 years at diagnosis.

Aim: Manatū Hauora, the Ministry of Health of New Zealand (NZ), published minimum standards for molecular testing of colorectal cancers (CRCs) in June 2018. These included mismatch repair (MMR) testing at diagnosis and BRAFV600E mutation analysis on newly diagnosed stage IV CRCs. This study aimed to determine the proportion of patients with CRC in the South Island of NZ with metastatic deficient mismatch repair (dMMR) CRC, the proportion of metastatic CRCs and dMMR CRCs that have a BRAFV600E mutation, and audit testing for BRAF mutations and appropriate referral to genetics services.

Objective: This study investigated the association between loss of MSH2/MSH6 versus loss of MLH1/PMS2 expression and overall survival and disease-free survival in patients with localized colorectal cancer.
Background: The risk of developing colorectal cancer varies depending on the expression of mismatch repair proteins. However, it is unknown if the prognosis differs accordingly.

Survival is poor for patients with metastatic cancer, and it is vital to examine new biomarkers that can improve patient prognostication and identify those who would benefit from more aggressive therapy. In metastatic prostate cancer, 2 new assays have become available: one that quantifies the number of cancer cells circulating in the peripheral blood, and the other a marker of the aggressiveness of the disease. It is critical to determine the magnitude of the effect of these biomarkers on the discrimination of a model-based risk score.
