Dense tumor-infiltrating lymphocytes (TILs) in liver metastasis from colorectal cancer are related to improved overall survival.

Background And Objectives: Tumor-infiltrating lymphocytes (TILs) represent a host-tumor interaction, frequently signifying an augmented immunological response. Nonetheless, implications with survival outcomes in patients with colorectal carcinoma liver metastasis (CRLM) warrant rigorous validation. The objective was to demonstrate the association between TILs and survival in patients with CRLM.

Pressurized Intraperitoneal Aerosol Chemotherapy (PIPAC): The First Reported Case in Brazil Using Standardized Technique with the Capnopen® Nebulizer Device.

BACKGROUND Peritoneal metastasis is a common progression of abdominal-pelvic cancers, and it is associated with poorer oncological prognosis when compared to other metastasis sites. Its treatment has limited results, mainly because of poor bioavailability of chemotherapy within the abdominal cavity after systemic administration. Pressurized intraperitoneal aerosol chemotherapy (PIPAC) has been proposed as a novel method to deliver chemotherapy directly into the peritoneal surface; it combines the effectiveness and response of an intraperitoneal therapy with benefits of a minimally invasive approach.

Short-term outcomes after vascular resection for pancreatic tumors: Lessons learned from 72 cases from a single Brazilian Cancer Center.

Introduction: Pancreatic malignant tumors are resectable at diagnosis in only 15% to 20% of cases and invasion of vascular structures is commonly present. Therefore, extended resections are needed for adequate local control and negative margins. However, morbidity and mortality associated with these enlarged resections are limiting factors.
