Metachronic Brain Metastases After Esophagectomy for Esophageal Cancer (METABREC)

Description

Esophagectomy is the cornerstone of the curative treatment of esophageal carcinoma. Despite this treatment, patients can suffer from locoregional or distant metastatic disease and only a very selected group of patients can be cured: mostly those with recurrence in one single organ. Brain metastases are rare after esophagectomy for cancer, but they have a serious impact on survival. Agressive treatment is often moren difficult for brain metastases compared to other metastases and some risk factors have been identified earlier. There is an impression that the incidence of brain metastases in esophageal cancer patients has increased since the introduction of neoadjuvant treatment schemes. However, this is not clear yet. A potential explanation could be that chemotherapy disturbs the blood-brain-barrier, hereby facilitating the migration of tumor cells to the brain. The purpose of this study is to retrospectively analyze the incidence and potential risk factors of brain metastases in patients who underwent esophagectomy for esophageal cancer. Patients treated between 2000 and 2019 will be included and outcome parameters are Odds Ratio for brain metastases (comparison between primary surgery and neoadjuvant treatment followed by surgery), time to recurrence and risk factors, number and characteristics of the brain metastases.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
