October 25, 2016 updated by: Jie Zhang, Shanghai Chest Hospital

Establishment and Evaluation for Pathological Diagnostic Criteria of Intraoperative Frozen Section of Early Stage Lung Cancer

The purpose of this study is:

  1. To establish a set of diagnostic criteria of intraoperative frozen section of early stage lung adenocarcinoma, including clinicopathologic and molecular characteristics.
  2. To assess its clinical usefulness in guiding surgical procedure for early stage lung adenocarcinoma.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The detection rate of small pulmonary nodules is increasing due to the widespread use of high-resolution computed tomography (CT) screening in clinical practice. These minute pulmonary nodules are suggestive of atypical adenomatous hyperplasia (AHH), adenocarcinoma in situ (AIS), minimally invasive adenocarcinoma (MIA), and invasive adenocarcinoma. Hence, the precision diagnosis of intraoperative frozen section is particularly imperative for its fundamental role in assess indeterminate lung lesions and guide the extent of subsequent surgical procedure.

However, it is still difficult for the surgical pathologist to apply the various features according to the newly revised WHO classification of lung adenocarcinoma (2015) to guide surgical management due to their unascertained accuracy or heterogeneity of lung cancer or technique problem. Therefore, the establishment and assessment for a set of diagnostic criteria of intraoperative frozen section of early stage lung adenocarcinoma are our primary aim in this study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

Experimental: OCT treatment
Randomly assigned patients whose small pulmonary nodules are inflated with the diluted OCT medium (2:3) used for frozen section, and then detected under microscope for their histopathological characteristics, by immunostaining for specific protein expression, by NGS (next-generation sequencing) for driver mutations.

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.
