Renal cell carcinoma (RCC) is the most common type of renal tumor arising from the proximal renal tubules. Extrarenal RCC is a rare case in which a tumor is found outside the kidney with no primary kidney tumor. Some theories suggest that these tumors arise from mesoderm remnant. Here, we present a unique case, the fourth in literature, of peri-renal, Extrarenal RCC case and the first case with a huge mass with distant metastases and aggressive progression.

Grading systems and perineural invasion in oral squamous cell carcinoma - a disease-specific survival analysis.

Background: Oral squamous cell carcinoma (OSCC) is an aggressive cancer, with prognosis influenced by clinical variables as well grading systems and perineural invasion (PNI), which are associated to poorer outcomes, including higher rates of recurrence and metastasis. This study aims to evaluate OSCC using three grading systems and assess the impact of PNI and clinicopathologic parameters on patient survival.
Material And Methods: Eighty-one primary OSCC samples were analyzed.
Significance of adding chemotherapy to radiotherapy in the treatment of T2N0 glottic cancer.

The prognosis for T2N0 glottic squamous cell carcinoma (SCC) is generally favorable, with a 5-year overall survival rate of 79%-96% achieved with radiotherapy (RT), the standard nonsurgical treatment for this condition. However, the local control rate for T2N0 glottic SCC treated with RT remains suboptimal, with a 5-year local control rate of only 65%-80%. Local residual disease or recurrence following RT for T2N0 glottic SCC often leads to difficulties in laryngeal preservation.

This study aims to investigate the expression of seven cancer testis antigens (MAGE-A1, MAGE-A4, MAGE-A10, MAGE-A11, PRAME, NY-ESO-1 and KK-LC-1) in pan squamous cell carcinoma and their prognostic value, thus assessing the potential of these CTAs as immunotherapeutic targets. The protein expression of these CTAs was evaluated by immunohistochemistry in 60 lung squamous cell carcinoma (LUSC), 62 esophageal squamous cell carcinoma (ESCA) and 62 head and neck squamous cell carcinoma (HNSC). The relationship between CTAs expression and progression-free survival (PFS) was assessed.

Introduction: Complete radical resection is crucial for successfully treating thymic carcinomas. However, when the invasion of the great vessels or the heart in Masaoka III and IV stages occurs, the management poses more challenges. The R0 resection often requires neoadjuvant treatment.
