Fluorouracil Bolus Use in Infusional Regimens Among Oncologists-A Survey by Brazilian Group of Gastrointestinal Tumors.

Purpose: The utility of administering fluorouracil (5-FU) in bolus in regimens of infusional 5-FU has been questioned. We aimed to quantify the use of 5-FU bolus in infusional regimens for gastrointestinal malignancies among Brazilian oncologists.

Methods: This was a cross-sectional electronic survey composed of eight multiple-choice questions sent to Brazilian oncologists during 14 days in February 2021.

Brazilian Group of Gastrointestinal Tumours' consensus guidelines for the management of oesophageal cancer.

Oesophageal cancer is among the ten most common types of cancer worldwide. More than 80% of the cases and deaths related to the disease occur in developing countries. Local socio-economic, epidemiologic and healthcare particularities led us to create a Brazilian guideline for the management of oesophageal and oesophagogastric junction (OGJ) carcinomas.

Brazilian Group of Gastrointestinal Tumours' consensus guidelines for the management of gastric cancer.

Gastric cancer is among the ten most common types of cancer worldwide. Most cases and deaths related to the disease occur in developing countries. Local socio-economic, epidemiologic and healthcare particularities led us to create a Brazilian guideline for the management of gastric carcinomas.

Differences in Pathology and Mutation Status Among Colorectal Cancer Patients Younger Than, Older Than, and of Screening Age.

Background: Screening protocols for colorectal cancer are broadly recommended and effective in reducing mortality. However, populations from different age groups can harbor distinct pathologic and molecular profiles that can also be influenced by screening and polyp resection, especially in older ages.

Patients And Methods: We retrospectively analyzed tumors from stage IV colorectal cancer patients from a central pathology laboratory in Brazil that is a reference for mutational profiling countrywide.

Evidence-based recommendations for gastrointestinal cancers during the COVID-19 pandemic by the Brazilian Gastrointestinal Tumours Group.

Purpose: As of 2020, the world is facing the great challenge of the COVID-19 (Coronavirus disease 2019) pandemic, caused by the SARS-CoV-2 virus. While the overall mortality is low, the virus is highly virulent and may infect millions of people worldwide. This will consequently burden health systems, particularly by those individuals considered to be at high risk of severe complications from COVID-19.
