Screening for Lung Cancer in the HIV Patient

Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins200 enrolled

Overview

That computed tomography (CT) screening of HIV-seropositive heavy smokers will detect early stage lung cancer at significantly higher rates than what is currently being observed.

The study design is that of a prospective cohort study in which 200 smoking participants will be recruited from an existing HIV-seropositive cohort of 800 patients (the Human Oral Papillomavirus Etiology (HOPE) Study). Participants will be enrolled from the Johns Hopkins HIV (Moore) Clinic and the resources of the Johns Hopkins Adult Outpatient General Clinical Research Center (GCRC) and pilot project funding from the Lung Cancer SPORE will be utilized to fund the costs of the CT scans. An interdisciplinary team with expertise in HIV-associated malignancy, CT screening, lung cancer surgery, HIV infection, epidemiology and biostatistics has been assembled to test the hypothesis by accomplishing the following Specific Aims:

Study Type

OBSERVATIONAL

Enrollment

200

Conditions

Lung Cancer in the HIV Patient HIV Infections HIV Seropositivity Lung Cancer

Interventions

CT Scan with SpirometryDEVICE

During the screening and later during the five annual study visits the patients will be scheduled to undergo total of five CT scans. The first CT scan will take place at the beginning of the study and then each year for a period of five years.

Outcomes

Primary Outcomes

Stage distribution of HIV-seropositive patients

To determine differences in stage distribution of HIV-seropositive patients at lung cancer diagnosis between those who are screened by spiral CT and historic controls.

Time frame: Day 1

Secondary Outcomes

To create a specimen bank of serum, sputum, and tissue

To create a specimen bank of serum, sputum, and tissue from the cohort of heavy smokers with HIV at high risk for lung cancer identified in Specific Aim 1.

Time frame: 5 years
