Synchronous Gastric and Colon Cancer.

Colorectal cancer (CRC) and gastric cancer, ranking as the third and fifth most prevalent global cancers, respectively, have seen increased diagnoses due to advancements in early detection and extended lifespans. Synchronous and metachronous cancers, with a rare incidence, are notable, with CRC being the predominant synchronous occurrence in gastric cancer patients. Screening CRC patients for gastric cancer is debated due to its low incidence, underscoring the crucial role of early diagnosis.

Technological Improvements in Low- and Middle-Income Countries (LMICs): A Review of the Literature and the "Sociedad de Lucha Contra el Cáncer" (SOLCA) Institutional Experience in Neuro-Radiosurgery During the Coronavirus Disease 2019 (COVID-19) Pandemic.

Objective: Neurosurgery is a medical field that requires specialized professionals and equipment, 2 important but scarce resources in low- and middle-income countries. Our goal was to report our experience with the replacement and implementation of linear accelerators with radiosurgery capabilities at "Sociedad de Lucha Contra el Cáncer" (SOLCA) Hospital in Quito, Ecuador, and give some recommendations for future technological replacements (TRs).

Methods: Two surveys were performed in SOLCA's radiosurgery department, one before the TR was finalized and one after, consisting of an open and multiple-choice questionnaire.

Management of an Unusual Metastasis of Cervical Cancer in the Adrenal Bed With Stereotactic Ablative Body Radiation Therapy.

Uterine cervical carcinoma is an important type of cancer among Ecuadorian women, especially in adult women. Survival rates have improved with the development of radiotherapy, surgical techniques, and chemotherapy. However, recurrence and/or metastasis are not unusual phenomena.

[Recommendations for the management of pancreatic cancer type adenocarcinoma: A consensus statement reached during the 2015 Latin American Symposium on Gastroenterological Oncology].

Pancreatic cancer is a malignancy of great impact in developed countries and is having an increasing impact in Latin America. Incidence and mortality rates are similar for this cancer. This is an important reason to offer to the patients the best treatments available.

Stomach cancer burden in Central and South America.

Rationale And Objective: Stomach cancer mortality rates in Central and South America (CSA) are among the highest in the world. We describe the current burden of stomach cancer in CSA.

Methods: We obtained regional and national-level cancer incidence data from 48 population-based registries (13 countries) and nation-wide cancer deaths from WHO's mortality database (18 countries).
