Treatment Registry of Alectinib in Anaplastic Lymphoma Kinase (ALK)-Positive, Locally Advanced or Metastatic Non-Small Cell Lung Cancer in Korea

An AE is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as AEs. All AE events will be graded according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0.

ORR will be determined according to Response Evaluation Criteria In Solid Tumors (RECIST) criteria version 1.1 as assessed by physicians under routine clinical practice. Overall response rate was defined as the percentage of participants who had any evidence of Complete Response (CR) or Partial Response (PR): CR is defined as the disappearance of all target lesions and all nodes with short axis <10 millimeter (mm); PR is defined as >/=30% decrease in the sum of the longest diameter of target lesions. Target lesions are those lesions with longest diameter >/=10 mm and limits that are sufficiently well defined for their measurement to be considered reliable. Lymph nodes are target lesions if short-axis measures >/=15 mm. Maximum number of selected target lesions is 5 per participant and 2 per organ. Overall Response (OR) = CR + PR.

CR will be determined according to RECIST v1,1 as assessed by physicians under routine clinical practice and is defined as disappearance of all target lesions and all nodes with short axis <10 mm. Target lesions are those lesions with longest diameter >/=10 mm and limits that are sufficiently well defined for their measurement to be considered reliable. Lymph nodes are target lesions if short-axis measures >/=15 mm. Maximum number of selected target lesions is 5 per participant and 2 per organ.

PR will be determined according to RECIST v1.1 as assessed by physicians under routine clinical practice and is defined as >/=30% decrease in the sum of the longest diameter of target lesions. Target lesions are those lesions with longest diameter >/=10 mm and limits that are sufficiently well defined for their measurement to be considered reliable. Lymph nodes are target lesions if short-axis measures >/=15 mm. Maximum number of selected target lesions is 5 per participant and 2 per organ.

SD will be determined according to RECIST v1.1 as assessed by physicians under routine clinical practice and is defined as neither response nor progression. Response is defined as at least >/=30% decrease in the sum of the longest diameter of target lesions. Progression is defined as >/= 20% increase in the sum of target lesions taking as reference the smallest sum measured during follow-up and >/= 5 mm in absolute value. Target lesions are those lesions with longest diameter >/=10 mm and limits that are sufficiently well defined for their measurement to be considered reliable. Lymph nodes are target lesions if short-axis measures >/=15 mm. Maximum number of selected target lesions is 5 per participant and 2 per organ.

PD will be determined according to RECIST v1.1 as assessed by physicians under routine clinical practice and is defined as >/=20% increase in the sum of target lesions taking as reference the smallest sum measured during follow-up and >/= 5 mm in absolute value. Target lesions are those lesions with longest diameter >/=10 mm and limits that are sufficiently well defined for their measurement to be considered reliable. Lymph nodes are target lesions if short-axis measures >/=15 mm. Maximum number of selected target lesions is 5 per participant and 2 per organ.
