Treatment strategies in patient with gastric and gastroesophageal junction tumors
06/2018 MUDr. Peter Grell, Ph.D.; MUDr. Radka Obermannová, Ph.D.
Gastric and gastro-oesophageal junction cancers are aggressive diseases, and only 25 % of patients with early stage disease achieve a long-term survival. The modern multimodal approach to treatment nearly doubled survival in these patients. The primary requirement for successful treatment is performing adequately radical resection in centers specialized in these challenging surgeries. In gastric cancer, the use of perioperative chemotherapy is recommended as a standard of care. The most effective regime in this approach is FLOT chemotherapy. In gastro-oesophageal junction carcinomas, in addition to perioperative therapy, neoadjuvant chemoradiotherapy appears to be appropriate strategy, mostly in cases with locally advanced carcinomas where tumor regression is required in order to perform an R0 resection.

News in the adenocarcinoma of oesophagus and gastric adenocarcinoma treatment – present and future
02/2017 MUDr. Radka Obermannová, Ph.D.
Adenocarcinoma of distal oesophagus and gastric adenocarcinoma still have a poor clinical outcome. In locally advanced adenocarcinoma multimodal treatment has reached maximum of median overall survival. New molecular predictors defined recently by The Cancer Genome Atlas offer an opportunity of patient stratification to optimal treatment approach. PET/CT is a valuable method providing earlier identification of non-responders and enabling a well-timed change of ineffective treatment. Metastatic gastric cancer is very heterogeneous disease. Trastuzumab is the only clinically valid targeted therapy with a known molecular predictor. Antiangiogenic treatment is a standard of care in the second line treatment. Despite promising phase I/II clinical trials results, several phase III studies assessing receptor tyrosine kinase-related signaling pathways such as epidermal growth factor receptor, hepatocyte growth factor receptor (MET/HGF) or mammalian target of rapamycine receptor (mTOR) failed. Novel treatment targets include activation of immune response by PD-1/PD-L1 checkpoint inhibitors, inhibition of cancer stemness-related signaling pathways like STAT3, targeting DNA damage repair, stroma modification by matrix metalloproteinase-9 inhibition and Claudin-18.2, a tight junction protein antibody.
