Study For Patients With Untreated Gastric Cancer Who Will Receive Capecitabine And Lapatinib

PFS is defined as the time from the initial treatment until the first observation of disease progression or death due to any cause. The date of documented disease progression was defined as the earliest date of radiographic disease assessment progression or symptomatic progression, whichever came first. For participants who did not die/progress, survival was censored at the time of the last assessment (or contact).

Overall survival is defined as the time from the initial treatment until death due to any cause. A death occurring during the study is defined as a death occurring during treatment or within 30 days of the last administration of study medication.

Time to progression is defined as the time from the initial treatment (first dose) until the first documented radiological symptomatic sign of disease progression. Time to progression data are presented as cumulative incidence estimate, which is defined as the time from the initial treatment until crude hazard probability of the occurrence of a particular event is reached to a particular point. All factors that hinder the observation of the event are defined as competing risks.

Time to progression is defined as the time from the initial treatment (first dose) until the first documented radiological symptomatic sign of disease progression. Time to progression data are presented as cumulative incidence estimate, which is defined as the time from the initial treatment until crude hazard probability of occurrence of a particular event is reached to a particular point. All factors that hinder the observation of the event are defined as competing risks.

Time to response is defined as the time from the initial treatment until the first documented evidence of CR (disappearance of all TLs and non-TLs and the appearance of no new lesions) or PR (>= a 30% decrease in the sum of the longest diameter of TLs, taking as reference the Baseline sum longest diameter) (whichever status was recorded first). Time to response data are presented as cumulative incidence estimate, which is defined as the time from the initial treatment until crude hazard probability of the occurrence of a particular event is reached to a particular point.

Duration of response is defined as the time from the first documented evidence of tumor response (CR or PR) until the first documented sign of disease progression or death due to any cause, whichever came first.

Best overall response was evaluated by the investigator based on RECIST criteria: CR; PR; Stable Disease (SD), defined as no sufficient shrinkage to qualify for PR, no sufficient increase to qualify for progressive disease (PD), taking as reference the smallest sum LD since the treatment started; PD, defined as at least a 20% increase in the sum of the LD of target lesions, taking as a reference the smallest sum LD recorded since the treatment started or the appearance of >= 1 new lesions; Unknown, defined as participants who do not have CR, PR, SD, or PD.
