Lung Cancer Screenings
The OSUCCC – James offers comprehensive screening for people at high risk for lung cancer. High-risk individuals include:
- 55-77 years old
- Tobacco history of at least 30 pack years (one pack year = smoking one pack per day for one year; 1 pack = 20 cigarettes)
- Current smoker or one who has quit within the last 15 years
Lung-cancer screening at the OSUCCC – James, which starts with low-dose computed tomography (CT), is more comprehensive than at nearly any other hospital or commercial laboratory in the United States.
Our experts are highly trained to understand all lung cancers, their complexities and how they act and react differently in each person. And understanding what drives each patient’s own specific genes to change enables our team — world-renowned experts across multiple medical disciplines and treatment modes — to offer individualized, targeted therapies found only here at the OSUCCC – James.
OSUCCC – James screenings also include a same-day consultation with a board-certified pulmonologist and if you would like, a certified smoking-cessation specialist as well.
Diagnosing Lung Cancer
An accurate, complete diagnosis is essential for effectively treating lung cancer. Because there is no routine lung cancer, the OSUCCC – James’ world-renowned lung cancer subspecialists reach across multiple disciplines and modes of treatment, working together to offer patients the latest technologies and the most advanced procedures to understand lung cancer at the molecular and genetic levels — the levels that drive each patient’s specific kind of lung cancer.
Our team includes experts who specialize in lung cancer — and only lung cancer, 24/7 — studying, discovering, researching and treating each kind, and developing and delivering leading-edge therapies to stop it in its tracks.
Diagnostic Tests for Lung Cancer
When a patient first experiences lung cancer symptoms or has a positive screening result, one or more tests can help detect lung cancer and determine if it has spread. The first diagnostic tests ordered usually include:
Chest CT scan or PET/CT scan
Using these tests, a physician can get detailed information about the size, position, and activity of abnormalities in the lungs.
An abnormal chest radiograph may lead to other tests to help physicians diagnose lung cancer. These tests may include:
A bronchoscope is a small, flexible tube with a tiny camera. A doctor inserts the bronchoscope through the nose or mouth and into the lungs while the patient is under light or general anesthesia. The physician also can use the bronchoscope to take a small tissue sample for biopsy.
Also called trans-thoracic needle biopsy, this procedure involves placing a small needle through the chest and directly into the area of the lung that looks suspicious. The physician uses radiography or CT scanning to guide the needle into place and suction to remove a small amount of tissue to examine under a microscope.
The physician uses ultrasound equipment to guide a biopsy (tissue sample) for lung cancer and to check for signs that the cancer may have spread to nearby lymph nodes.
Endoscopic Esophageal Ultrasound
An endoscopic esophageal ultrasound creates images of the stomach lining, esophagus and duodenum. A small, flexible tube is placed inside the esophagus, and high-frequency ultrasound waves create images that allow experts to examine any growths in the wall of the esophagus from the lungs or chest and also to examine lymph nodes in the chest.
A mediastinoscopy is a surgical procedure to examine the space behind the breastbone in the middle of the chest (between the lungs). After the patient receives general anesthesia, the surgeon places something called a mediastinoscope through a small incision in the neck to take tissue samples from lymph nodes near the airways.
A thoracentesis removes fluid from the space between the lungs and the interior chest wall, which is called the pleural space, in cases where fluid is observed there on scans. The procedure involves placing a needle into the back of a patient’s chest wall through to the pleural space and collecting fluid, which then gets sent to the laboratory for analysis. When a patient has a lung disease, the space can fill with fluid and cause shortness of breath. Analyzing fluid from this space can help diagnose lung cancer.
In a thoracoscopy, a physician uses an endoscope (a small, flexible tube with a tiny camera on the end) to visually examine the lungs, pleura and mediastinum. The surgeon also can use the endoscope to remove a small sample of tissue for biopsy. Patients usually have general anesthesia for this procedure.
Diagnostic medical imaging exams might include the following:
- Computed Tomography (CT) scanning, which use X-rays to capture cross-sectional images of the lungs
- Magnetic Resonance Imaging (MRI) scans, which use powerful magnets to capture high-resolution images
- Positron Emission Tomography (PET) scans, a nuclear medicine technology that finds spots of cancer activity in the body
Some of these imaging tests, such as CT and PET, are also used to see how well a patient’s lung cancer treatment is working.
Next-Generation Sequencing of Tumor DNA
At the OSUCCC – James, our leading-edge, treatment-planning approach begins with a genetic analysis of the tumor DNA, including something called “next-generation sequencing,” and our experts perform this for every patient with advanced non-squamous non-small cell lung cancer.
This advanced technology pinpoints the genes that are actually driving the patient’s lung cancer, and our testing is among the most comprehensive available, testing for more genetic mutations and molecular changes than nearly any other hospital or commercial laboratory in the nation.
Additionally, detailed expert analysis enables our team of lung cancer sub-specialists to develop and deliver the most effective, targeted treatments for each patient’s unique lung cancer. In fact, our experts can often match patients to targeted treatments that are available only in clinical trials conducted at the OSUCCC – James.
Lung Cancer Staging
Lung cancer staging depends mainly on three things:
- The size of the tumor
- How much the tumor has invaded nearby normal tissues (such as the chest wall), and
- Whether lung cancer cells have spread to lymph nodes or other parts of the body
Stages of Small Cell Lung Cancer
Most doctors describe small cell lung cancer in two stages:
Cancer is found only within the chest in an area that can safely be entirely treated with radiation therapy.
Cancer has spread to an extent that all of the tumor cannot be encompassed in a tolerable radiation field.
Stages of Non-Small Cell Lung Cancer
Stages of non-small cell lung cancer are described using Roman numerals. Stage I is early-stage cancer, and stage IV is advanced cancer that has spread to other parts of the body, such as the bones. This staging can also be applied to small cell lung cancer.
Tumor cells are found in sputum, but CT scans and other imaging tests don't show a lung tumor.
Abnormal cells are found only in the lung’s innermost lining. The tumor has not grown through this lining. A stage 0 tumor is also called carcinoma in situ. It is not an invasive cancer.
The lung tumor is no more than 3 centimeters across, and cancer cells have not moved into surrounding tissue or lymph nodes.
No lymph nodes have tumor cells. The tumor is more than 3 centimeters but less than 7 cm across or has grown into the bronchus or the pleura.
The lung tumor is less than 5 centimeters across, and cancer cells are found in nearby lymph nodes.
The tumor is 5-7 cm in size, and lung cancer cells are found in the lymph nodes near the lungs.
The tumor is greater than 7 cm in diameter or lung cancer cells are found in the lymph nodes between the lungs, and the tumor is in other nearby organs, such as the esophagus, heart or trachea, or tumors are found in more than one lobe of the same lung.
Malignant cells are found in both lungs, the fluid around the lungs or in other organs of the body, such as the brain, liver or bone.
