Human Epidermal Growth Factor Receptor 2 (HER-2) Status in Gastric and Gastro-Esophageal Junction (GEJ) Carcinoma

September 8, 2016 updated by: Hoffmann-La Roche

Evaluation of Human HER-2 Status in Gastric and Gastro-Oesophageal Junction Cancer.

The primary objective is to evaluate the concordance between human epidermal growth factor receptor 2 (HER2) status determined by the participating laboratory and by the centralized laboratory. HER2 status of samples was tested by the participating laboratories (investigator's choice of immunohistochemistry [IHC] and in situ hybridization [ISH] methods) and by the centralized laboratories (IHC using the 4B5 anti-HER antibody and Silver ISH). Positive HER2 status was defined as a score of IHC3+ or IHC2+/ISH+.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Simple Kappa Coefficient of Human Epidermal Growth Factor Receptor 2 (HER-2) Status Between Local and Centralized Laboratory Assessments
Time Frame: At enrollment
Positive HER-2 status was defined as either immunohistochemistry (IHC) score of 3+ or IHC score 2+/in situ hybridization (ISH) score +, as per the trastuzumab Summary of Product Characteristics (SPC). The HER-2 status in tumor specimens was determined using the pathologist's choice of IHC and ISH techniques in local laboratories, and using IHC 4B5 and silver ISH (SISH) in centralized laboratories. The kappa coefficient was used to evaluate the true concordance between the HER-2 status determined by local and centralized laboratories. The kappa coefficient value was interpreted according to the Landis and Koch classification as follows: a) less than (<) 0: less than chance agreement, b) 0.01-0.20: slight agreement, c) 0.21-0.40: fair agreement, d) 0.41-0.60: moderate agreement, e) 0.61-0.80: substantial agreement, and f) 0.81-0.99: almost perfect agreement.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Cancer Characteristics: Percentage of Participants With Initial Location of Adenocarcinoma in Stomach Versus Esogastric Location
Time Frame: At enrollment
At enrollment
Cancer Characteristics: Percentage of Participants With Samples in Each of the Histologic Type Lauren's Classifications, Including Diffuse Type, Intestinal and Mixed
Time Frame: At enrollment
The Lauren classification is based on examination of histologic specimens under the microscope and divides adenocarcinoma of the stomach into 3 types: 1) Diffuse type: tumor cells are poorly differentiated, behave aggressively and tend to scatter throughout the stomach (rather than form glands). This type metastasizes to other parts of the body much quicker than intestinal type tumors, 2) Intestinal type: tumor cells are well differentiated, grow slowly and tend to form glands, 3) Mixed type: this type is made up of both intestinal and diffuse types.
At enrollment
Cancer Characteristics: Percentage of Participants With Samples in Each of the Tumor-Node-Metastasis (TNM) Stages
Time Frame: At enrollment
The TNM stage system includes information about the size of the primary tumor (T), whether the cancer has spread to nearby lymph nodes (N) and whether the cancer has metastasized to other parts of the body (M). In the T classification TX indicates that the main tumor cannot be measured, T1, T2, T3 and T4 refer to the size and/or extent of the main tumor. The higher the number after the T, the larger the tumor or the more it has grown into nearby tissues. In the N classification NX indicates that the cancer in nearby lymph nodes cannot be measured, N0 indicates that there is no cancer in nearby lymph nodes, N1, N2 and N3 refer to the number and location of lymph nodes that contain cancer. The higher the number after the N, the more lymph nodes that contain cancer. In the M classification MX indicates that the metastasis cannot be measured, M0 indicates that the cancer has not spread to other parts of the body and M1 indicates that the cancer has spread to other parts of the body.
At enrollment
Weighted Kappa Coefficient Between Immunohistochemistry (IHC) 4B5 and Silver in Situ Hybridization (SISH) Techniques for HER-2 Testing in Centralized Laboratories
Time Frame: At enrollment
Positive HER-2 status was defined as either immunohistochemistry (IHC) score of 3+ or IHC score 2+/in situ hybridization (ISH) score +, as per the trastuzumab Summary of Product Characteristics (SPC). The HER-2 status in tumor specimens was determined using IHC 4B5 and silver ISH (SISH) in centralized laboratories. The weighted kappa coefficient was used to evaluate the true concordance between the HER-2 status determined by IHC 4B5 and SISH. The weighted kappa coefficient value was interpreted according to the Landis and Koch classification as follows: a) less than (<) 0: less than chance agreement, b) 0.01-0.20: slight agreement, c) 0.21-0.40: fair agreement, d) 0.41-0.60: moderate agreement, e) 0.61-0.80: substantial agreement, and f) 0.81-0.99: almost perfect agreement.
