Current clinical practice in the management of Brazilian patients with potentially resectable pancreatic ductal adenocarcinoma (PDAC).

Background And Objectives: We aimed to describe the routine clinical practice of physicians involved in the treatment of patients with localized pancreatic ductal adenocarcinoma (PDAC) in Brazil.

Methods: Physicians were invited through email and text messages to participate in an electronic survey sponsored by the Brazilian Gastrointestinal Tumor Group (GTG) and the Brazilian Society of Surgical Oncology (SBCO). We evaluated the relationship between variable categories numerically with false discovery rate-adjusted Fisher's exact test p values and graphically with Multiple Correspondence Analysis.

Unresectable metastatic colorectal cancer in fit patients - a practical algorithm of treatment sequencing from the Brazilian Group of Gastrointestinal Tumours (GTG).

Recent advances in biomarker-driven therapies have changed the landscape of unresectable metastatic colorectal cancer (mCRC) and brought not only access issues but also difficulties for the treating physician (especially generalist oncologists) in choosing the most suitable treatment for each individual patient. This manuscript proposes an algorithm developed by The Brazilian Group of Gastrointestinal Tumours with the aim of bringing easy-to-follow steps in the management of unresectable mCRC. The algorithm is based on evidence for fit patients to facilitate therapeutic decisions in the clinical practice and assumes that there are no access and resource limitations.

Vitamin D and colorectal cancer - A practical review of the literature.

Colorectal cancer (CRC) is the third leading cause of cancer-related mortality in the United States and the second cause worldwide. Its incidence rates have been decreasing in the overall population in the US in the past few decades, but with increasing rates in the population younger than 50 years old. Environmental factors are supposed to be involved in the development of the disease, with strong evidence favoring an influence of the diet and lifestyle.

Biologics in rectal cancer.

Introduction: Despite the use of multimodality therapy, locally advanced rectal cancer (LARC) still presents high rates of disease recurrence. Fluoropyrimidine-based chemotherapy concurrently with radiation therapy (RT) remains the cornerstone of neoadjuvant therapy of LARC, and novel therapies are urgently needed in order to improve the clinical outcomes.

Areas Covered: We aim to summarize data from completed and ongoing clinical trials addressing the role of biological therapies, including monoclonal antibodies, immune checkpoint inhibitors (ICIs), antibody-drug conjugates, bispecific antibodies, and gene therapies in the systemic therapy of rectal cancer.

Efficacy and Safety Associated With Immune Checkpoint Inhibitors in Unresectable Hepatocellular Carcinoma: A Meta-analysis.

Importance: Immune checkpoint inhibitors (ICIs) have yielded conflicting results in hepatocellular carcinoma (HCC). The overall effect of ICIs compared with standard therapies in unresectable HCC requires more research.

Objective: To estimate the efficacy and safety associated with ICIs compared with standard therapies in patients with unresectable HCC.
