Trial summary

By literature review, there is a clear trend towards a potential role for human epidermal growth factor receptor 2 (HER2) as a negative prognostic factor in gastric cancer was shown, but only in half of the analyses used multivariate statistics. Read more about this study

About this study

Official title: Retrospective Study of Lauren Classifications and HER2 Status in Chinese Patients With Resectable Gastric Adenocarcinoma

By literature review, there is a clear trend towards a potential role for human epidermal growth factor receptor 2 (HER2) as a negative prognostic factor in gastric cancer was shown, but only in half of the analyses used multivariate statistics. Besides, For the studies in the current review that have looked at the Lauren classification in relation to HER2, a higher level of overexpression or amplification was found in the intestinal phenotype compared to the diffuse or mixed types. As lauren classification was reported as an independent prognostic factor result in favored outcomes in gastric cancer (GC), there may probably be histologic bias exists when compare overall survival (OS) between HER2 statuses without controlling this confounding. Similarly, patients with different disease settings (early stage and advanced stage; resectable and metastatic) affect outcomes either.

In this study, the investigators will retrospectively analyze HER2 status and lauren classification in 800 gastric patients who received gastrectomy in the Cancer Center of Sun Yat-Sen University between January 1996 and December 2006 with formalin-fixed and paraffin- embedded tumor tissue samples. To avoid potential influence by histologic classifications and disease settings, the investigators assess difference in OS between HER2 positive and HER2 negative groups in resectable Lauren classification of GCs, and further evaluate the prognostic value of HER2 status according to tumor-node-metastasis (TNM) stages.

Read the detailed description

It's a single site, retrospective study by review of medical records and tissue testing.

Eight hundred gastric adenocarcinoma patients with integrity medical record and regular survival follow up who received gastrectomy in the Cancer Center of Sun Yat-Sen University between January 1996 to December 2006 were retrospectively studied.

Formalin-fixed and paraffin-embedded tumor tissue samples were retrospectively tested by human epidermal growth factor receptor 2 (HER2) and Lauren classification status. Her2 positive was defined as: immunohistochemistry (IHC) 2+ and fluorescence in situ hybridization (FISH) +; or IHC 3+.

  1. After HER2 status and lauren classification identifying, population used in overall survival (OS) comparison between Cohort 1(HER2 positive) and Cohort 2 (negative group) were carried out. According to Tumor-node-metastasis (TNM) classification, OS were to be compared between cohorts by different stages.
  2. Correlate histopathological characteristics with HER2 status and lauren classification were performed in the total 800 patients. Meanwhile, independent prognostic factors identification was to be confirmed in clinicopathological features, including gender (male or female), age at diagnosis, tumor size (≤5cm or >5cm), location of primary tumor (proximal or distal), histology subtypes (well + moderate differentiated adenocarcinoma or poorly + signet ring cell differentiated adenocarcinoma), lauren classifications (diffuse type or intestinal type or mixed type), anemia (yes or no), angiolymphatic invasion (yes or no), the TNM staging system (American Joint Committee on Cancer (AJCC) 7th edition), and HER2 status (negative and positive).

Questions about this trial

What is this clinical trial studying?

An observational study of Gastric Cancer, run by Sun Yat-sen University at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 22 Aug 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overall survival (time frame: At least 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01927146, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Aug 2013.
