Treating gastric cancer has become an individualized process. By knowing more about the tumor (in terms of its biology and in terms of its molecular characteristics), the stage of the cancer, and other specific characteristics of the patient, a range of different modalities can be used, including surgery, as well as chemotherapy and radiation therapy. These systemic therapies can be conventional, or they can be targeted therapies or immune therapies.
Healthcare professionals can work on the treatment decisions and thus can be informed by the evolving treatment options for gastric cancer. However, these same healthcare professionals are faced with difficult decisions regarding the best evidence, patient-specific factors, potential toxicity, and goals of treatment.
