Coping and Support View All Historically, bronchogenic carcinoma was the term used to describe the origin of some types of lung cancer —namely those that arise in the bronchi the largest airways of the lungs and bronchioles. Now, this term is used interchangeably with lung cancer of all types. While the name bronchogenic carcinoma may sometimes be used in the old way—referring to lung cancers arising in the central airways instead of the periphery of the lungs—it is most often used to describe any type or subtype of lung cancer.

Symptoms of bronchogenic carcinoma may include a persistent cough, coughing up blood, or repeated lung infections. A chest CT scan and biopsy is the most common way in which it is diagnosed. Treatment options have expanded considerably in recent years, and now include surgery, radiation therapy, chemotherapy, targeted therapy, and immunotherapy. In addition, the incidence of non-small cell lung cancer in never smokers is increasing, especially in young women. Types There are 2 main types of bronchogenic carcinoma: Small Cell Lung Cancer: Small cell lung cancer is named for the appearance of the cells under a microscope small cells.

This type of cancer is present in approximately 15 percent of people with lung cancer. In a book published in titled Primary Malignant Growths of the Lungs and Bronchi, the author was only able to verify published cases of the disease. In , lung cancer is the leading cancer-related cause of death of both men and women in the United States. Over the last five decades, the most common types and location of lung cancer have changed. In the past, the most common forms were squamous cell lung cancer a type of non-small cell lung cancer and small cell lung cancer oat cell carcinoma.

At present, the most common form of lung cancer is lung adenocarcinoma. Instead of cancers such as squamous cell lung cancer and small cell lung cancer which usually arise in the large airways of the lungs, lung adenocarcinoma often arises in the distant airways in the periphery of the lungs. Of course, lung cancer occurs in never smokers as well as people who smoke, and adenocarcinoma is the most common form of lung cancer in never smokers.

Symptoms Using the older definition of bronchogenic carcinoma, symptoms are often related to the growth of cancer in the large airways. These tumors tend to grow in the periphery of the lungs, rather than in the central airways like the bronchi, and for that reason, the typical symptoms noted above may be absent.

Some of these include: Radon exposure in the home: Radon is the second leading cause of lung cancer in people who smoke, and the number one cause of lung cancer in non-smokers. Air pollution Exposure to occupational lung carcinogens Diagnosis The diagnosis of bronchogenic carcinoma may be made in several ways. Sometimes a physician finds an abnormality on a chest x-ray prompting further evaluation with a chest CT scan or other imaging methods.

A PET scan may be done, as this is the most sensitive way of finding the spread of lung cancer and accurately staging the disease. This is important, as while surgery is the treatment of choice for early-stage lung cancer, it would not be recommended for people with metastatic lung cancer.

This is extremely important as newer treatments for some subtypes of lung cancer have become available. A test called next-generation sequencing is currently the gold standard, as it not only detects the greatest number of treatable mutations but is faster and cost-effective.

If you have non-small cell lung cancer, especially lung adenocarcinoma or squamous cell carcinoma, talk to your talk about possible gene mutations in your tumor. Though a lung biopsy is still the gold standard for doing this testing, a simple blood test called a liquid biopsy can also be done to look for mutations.

PD-L1 testing, and now tumor mutation burden testing, are tests that can sometimes estimate who will best respond to the immunotherapy drugs now available for lung cancer.

Screening Low-dose CT screening is now available for bronchogenic carcinoma, in people who meet certain criteria. Unfortunately, only a minority of people who are eligible for screening are currently screened, and too many people are diagnosed in the later incurable stages of a disease that could likely have been diagnosed at a curable stage with screening. Treatments The treatments your doctor recommends will depend on several factors, including the type and stage of lung cancer you are diagnosed with.

It is important to learn about your diagnosis, as studies suggest that people who are actively involved in their lung cancer care have better outcomes. Prognosis varies based on the type and stage of lung cancer, with survival rates being much better when diagnosed in the earlier stages of the disease.

Though these statistics are sobering, advances in the treatment of lung cancer are improving survival, even for people with metastatic stage 4 disease.
