    The EORTC QLQ-STO22 is a 22-item, self-reporting instrument consisting of 5 scales and 4 single items to assess health-related quality of life (HRQOL) issues related to dysphagia, eating restrictions, reflux, and abdominal pain, as well as specific symptoms that may occur during chemotherapy or radiation treatment. Scores are averaged and transformed to a 0-100 scale. For the symptom scales and items, a high score is equivalent to worse or more symptoms. In the functional scales, however, a high score is equivalent to better function.

  • Number of Participants With the Indicated Epidermal Growth Factor Receptor (EGFR) Immunohistochemistry Intensity in the Randomized Part of the Study [ Time Frame: Pretreatment ] [ Designated as safety issue: No ]
    EGFR protein expression on the surface of cells in gastric cancer tissue samples was measured using a moncolonal antibody specific for the extracellular region of EGFR, and the degree of membrane staining was evaluated. 3+ indicates positive EGFR expression; <3+ indicates negative EGFR expression.
  • Number of Participants With the Indicated Human Epidermal Growth Factor Receptor 2 (HER2) Immunohistochemistry Intensity in the Randomized Part of the Study [ Time Frame: Pretreatment ] [ Designated as safety issue: No ]
    HER2 protein expression on the surface of cells in gastric cancer tissue samples was measured using a monoclonal antibody specific for the extracellulr region of HER2, and the degree of membrane staining was evaulated. The immunohistochemistry test gives a score of 0 to 3+ and measures the amount of HER2 receptor protein on the surface of cells in a gastric cancer tissue sample. Score of 0 to 1+, "HER2 negative"; score of 2+, "borderline"; score of 3+, "HER2 positive."
  • Number of Participants With Mutations That May Correlate With Response and Toxicity to Lapatinib [ Time Frame: Pretreatment ] [ Designated as safety issue: No ]
    An inadequate number of tissue samples were obtained; thus, analysis could not be performed.
