In the last two decades, the incidence of gastroesophageal junction (GEJ) adenocarcinomas (AC) has increased, in part due to the increasing prevalence of obesity and untreated gastroesophageal reflux disease (GERD). Esophageal and GEJ cancers have become one of the leading causes of cancer deaths worldwide due to its aggressive nature. While the mainstay of treatment for locally advanced gastroesophageal cancers (GECs) remains surgery, several studies have now shown that multimodality approach yields better outcomes. GEJ cancers have historically been included both in esophageal cancer as well as gastric cancer trials. Therefore, both approaches, neoadjuvant chemoradiation (CRT) or perioperative chemotherapy are considered standard treatment options. thereon the same token, there yet remains a debate for the 'gold standard' treatment of locally advanced GEJ cancers. The landmark trials, fluorouracil, leucovorin, oxaliplatin, docetaxel (FLOT) and ChemoRadiotherapy for Oesophageal cancer followed by Surgery Study (CROSS), have shown similar improvements in overall survival (OS) and disease-free survival (DFS) for patients with resectable locoregional GEJ cancers. In this review, the authors attempt to highlight the historical evolution of current standard treatments and provide a sneak peek into the future of treatment of GEJ cancers. Several factors must be borne in mind when making the optimal choice for a patient. Some of these include surgical candidacy, tolerance to chemotherapy, eligibility for radiation (RT) as well as institutional preferences.
