Collision-type adenosquamous carcinoma of the colon with signet-ring adenocarcinoma: A rare case report.

Introduction And Importance: Adenosquamous carcinoma (ASC) of the colon is a rare malignancy, representing approximately 0.06 % of colorectal cancers (CRC). It is characterized by the coexistence of adenocarcinoma and squamous cell carcinoma components.

Primary Pulmonary Synovial Sarcoma With Extensive Myxoid Change Masquerading as a Lung Hydatid Cyst.

Synovial sarcoma is a rare malignant mesenchymal neoplasm primarily affecting adolescents and young adults, and it typically arises from deep soft tissues near large joints. Although commonly found in extremities, it can occur in various anatomic locations. We present a rare case of a 29-year-old man with primary pulmonary synovial sarcoma manifesting as a cystic mass masquerading as a lung hydatid cyst.

Exploring the clinicopathological parameters of HER2 low breast cancers: insights from a retrospective cohort study.

Purpose: Breast cancer subtypes are delineated by human epidermal growth factor receptor 2 (HER2) expression, pivotal in treatment selection. HER2-positive tumors typically respond to targeted therapies, whereas HER2-negative tumors lack HER2 overexpression. However, a subset exhibits low HER2 expression without amplification, termed HER2 low breast cancer.

Association of stromal tumor-infiltrating lymphocytes with clinicopathological parameters in endometrial cancer.

Purpose: Endometrial cancer (EC) ranks as one of the most prevalent gynecological malignancies globally. The presence and role of stromal tumor-infiltrating lymphocytes (TILs) in the tumor microenvironment have garnered interest due to their prognostic and therapeutic potential. This study aimed to evaluate the association between stromal TILs and various clinicopathological parameters in EC.

The evolution of cancer immunotherapy: a comprehensive review of its history and current perspectives.

Cancer immunotherapy uses the body's immune system to combat cancer, marking a significant advancement in treatment. This review traces its evolution from the late 19th century to its current status. It began with William Coley's pioneering work using bacterial toxins to stimulate the immune system against cancer cells, establishing the foundational concept of immunotherapy.
