Let’s Talk Lung Cancer: An In-Depth Interview with Dr. Reddy

Lung Cancer Awareness Month

Lung cancer is the leading cause of cancer deaths worldwide.1 In the United States, more people die from lung cancer than any other type of cancer.2 November is Lung Cancer Awareness Month, and to help us gain a better understanding of the condition, the screening process, and treatment options, we sat down with Chakravarthy Reddy, MD, pulmonologist at the University of Utah Huntsman Cancer Institute in Salt Lake City, UT.

What Is Lung Cancer?

Lung cancer occurs when cells in the lungs change or mutate, resulting in abnormal cell growth. These cells multiply uncontrollably, forming a tumor and spreading to other parts of the body.

“Stage one or stage two, where patients are potentially curable, have almost no symptoms at all; it’s always incidentally found,” Dr. Reddy explains. “A patient has a scan for some other reason, and the cancer is detected in the lungs.”

When lung cancer symptoms do manifest, they can include a cough that worsens or does not resolve, chest pain, shortness of breath, coughing up blood, wheezing, weakness or fatigue, and weight loss.4 “Unfortunately, by the time a patient presents with symptoms, they’re in advanced stages, and their survival is not as good,” says Dr. Reddy.

What Are Risk Factors for Lung Cancer?

Smoking is by far the leading cause of lung cancer, putting people who smoke at a significantly higher risk of developing lung cancer compared to non-smokers.5

In addition to smoking, breathing secondhand smoke is also dangerous, increasing the risk of lung cancer.6 “We always talk about smokers, but there is a correlation between people who live with smokers and their risk for developing lung cancer,” Dr. Reddy adds. “Secondhand exposure does increase the risk of developing cancer.”

The American Cancer Society lists other risk factors for lung cancer, which include:5

Risks and Warnings

A naturally occurring radioactive gas, radon is the breakdown of uranium in soil and rocks. Potential risk areas are homes with basements.

Asbestos is a mineral fiber that occurs in rock and soil.7 People who work with asbestos (e.g., in mines, mills, textile plants, shipyards, and where insulation is used) are several times more likely to die of lung cancer.

Exposure to cancer-causing agents, such as uranium, arsenic, beryllium, cadmium, nickel compounds, coal products, and diesel exhaust can increase lung cancer risk.

Personal or Family History
If an individual has lung cancer, there is a higher risk of developing another lung cancer. Brothers, sisters, and children of people who have had lung cancer may have a higher risk.

Previous Radiation Therapy to the Lungs
People who have had radiation therapy to the chest for other cancers are at a higher risk of lung cancer, particularly if they smoke.

Air Pollution
In cities, air pollution can increase the risk of lung cancer, with some research suggesting approximately 5% of all deaths from lung cancer may be due to outdoor air pollution.

Who Should Be Screened for Lung Cancer?

The recommended screening test for lung cancer is a low-dose CT scan.8 According to the United States Preventive Services Task Force, those eligible for screening must meet the three-pronged criteria:9

Age ǀ Adults aged 50-80 years
Smoking History ǀ Individuals with a 20 pack-year smoking history
Tobacco Exposure ǀ Current smokers or those who have quit within the past 15 years

Age is a straightforward benchmark, but calculating a pack-year may seem foreign to most. “Multiply the number of packs of cigarettes you smoke per day by the number of years you’ve smoked. This gives you the value, which we call pack-years,” Dr. Reddy explains. An example would be if a person has smoked a pack of cigarettes for 20 years or two packs for 10 years, each of these instances would calculate a 20 pack-year history.

The third criterion addresses tobacco exposure—but what is the significance of a 15-year time span? “It takes about 15 years for the risk [of lung cancer] to normalize,” Dr. Reddy says. “If it’s been less than 15 years since the patient quit, then the third criterion for lung cancer screening is met.”

This also means if a patient does not meet the criteria, screening will not happen. Dr. Reddy encourages people who are under 50 who have a 20 pack-year history to speak with a physician about any concerns, personal risk factors, and the benefits of being screened.

What Lung Cancer Treatment Options Are Available?

When lung cancer is caught early, there are more curative options. Unfortunately, as Dr. Reddy mentioned, lung cancer is normally caught in late stages. A surgery called a lobectomy, which removes one of the lobes in the lung, is only an option for stage 1 or 2 cancer. “Patients who come in with lung cancer don’t have healthy lungs to begin with,” Dr. Reddy says. “It’s more likely they also have emphysema from smoking, and they probably won’t tolerate removal of even a lobe.”

If a patient’s lung function is borderline, Dr. Reddy suggests another surgical option called a wedge resection, where the lobe is spared, and only the cancer is removed. “It’s not preferred, but if that’s the only option, it’s better than not doing anything,” Dr. Reddy says. “If their lung function is any worse than that, then we clearly cannot do any surgery at all. We have to think of second-line approaches, such as radiation therapy.”

According to Dr. Reddy, lung cancer that spreads first to the lymph nodes in the chest is still potentially curable. However, once it leaves the chest and invades the chest cavity and other parts of the body, such as the adrenal glands, the brain, or bones, it is potentially no longer curable. When this occurs, palliative care is the only option, relieving symptoms and mitigating suffering while optimizing patient quality of life.

Elation Pulmonary Balloon Dilater - Pulmonology Products - Merit Endoscopy

To relieve common lung cancer symptoms, such as shortness of breath or a persistent cough, there are options. “One of the things we do is use balloons to dilate [the airway passages],” Dr. Reddy explains. “Merit makes Elation® balloons, which we find extremely useful, especially because they are available in short, two-centimeter balloon configurations.”

AERO Tracheobronchial Stent - Pulmonology Products - Merit Med Endoscopy

A second approach is to stent the tumor in the lung to maintain the patency of the airway. An option for this line of treatment would be Merit’s AERO® Tracheobronchial Stents. “Patients notice an improvement immediately, almost right after they wake up from the procedure,” Dr. Reddy says. “The radial force of the AERO stent actually keeps the airway open, and that improves shortness of breath.”

Lung Cancer Awareness Resources

As lung cancer awareness is heightened this month, it is critical to share facts about the importance of screening with loved ones and encourage those who smoke to quit.

Knowledge is power, and having health resources to help understand lung cancer better is important. In addition to information about the disease, the below organizations provide a wide range of topics, including survivor stories and ways to get involved throughout the month, helping patients and families in their battle against lung cancer:

Lung Cancer Foundation of America
American Lung Association
GO2 Foundation for Lung Cancer

Addressing Complications of Esophageal Stenting with the EndoMAXX® Stent

EndoMAXX Esophageal StentFully covered self-expanding metal stents are commonly used for palliating malignant strictures. Merit Medical’s Endotek® division developed the EndoMAXX®, an esophageal stent indicated for maintaining esophageal luminal patency in esophageal strictures caused by intrinsic and/or extrinsic malignant tumors and for occlusion of esophageal fistulae.

There are numerous treatment options available to help in the palliation of a malignant esophageal obstruction, such as photodynamic therapy, thermal ablative techniques, surgical resection or bypass, and chemotherapy/radiotherapy. However, endoscopic stenting offers significant advantages over these other therapies, as stents are generally easy and quick to place. They are safe, have a good complication profile, and are well-tolerated with a low incidence of significant pain.1,2

Despite having a good complication profile, two common complications of esophageal stenting exist: chest pain and stent migration. The EndoMAXX is designed to address each.

Chest pain due to esophageal stent placement has incidence rates ranging from 12%3 to as high as 37%.4 This pain is typically due to the expansion force, or outward pressure, an esophageal stent exerts on esophageal tissue, a tumor, or a stricture when implanted. It is believed that this force directly corresponds to the discomfort the patient feels while the stent is in place. Clinical guidance also suggests this force may contribute to perforation, a life-threatening additional complication that can occur with an esophageal stent.

The expansion force of the EndoMAXX is 2.4 N, compared to 5.4 N of the market-leading esophageal stent in the US.5 In addition, the EndoMAXX stent is designed with 2.5 cm of flare at each end of the stent. This feature helps anchor the stent within the esophageal lumen. Soft flared ends and a firm mid-body help to dilate an obstruction while protecting healthy esophageal mucosa.

EndoMAXX - Example of Advanced Patient-Focused Design

Beyond having a lower radial force, the laser-cut design of the EndoMAXX has virtually no foreshortening or elongation of the stent during deployment, allowing for accurate sizing to the patient’s anatomy. A recent study published by Essrani et al. in Cureus Journal of Medical Science confirmed that “[t]he most common complication  . . . encountered was chest pain, which was transient and mostly resolved without any intervention.”2

In addition, a study by Dua et al. published in Gastrointestinal Endoscopy showed that “[c]hest pain was reported in 11% of patients, and in two-thirds of these cases chest pain developed several weeks after stent placement while the patients were receiving radiotherapy.” The authors concluded that “[t]he relatively low incidence of chest pain in this series could be related to the use of smallest-diameter (19 mm) stents in all patients with strictures.”1

AliMAXX-ES Fully Covered Esophageal StentTo meet the clinical need for a large-diameter stent, the EndoMAXX is available in 19-mm and 23-mm diameters. For clinical scenarios that require either a small diameter stent and/or when chest pain is a concern, Merit Endotek also offers the ALIMAXX-ES Esophageal Stent that is available in smaller diameters ranging from 12 mm to 22 mm. ALIMAXX-ES stents are designed to have a lower expansion force of 1.6 N, potentially reducing pain experienced by patients.

Migration is also a common complication of esophageal stent placement. Research shows migration rates for self-expanding metal stents range from 23 % to 31 % in malignant strictures. 6-8 In an effort to reduce migration, the EndoMAXX stent is designed with proprietary anti-migration struts that provide increased mucosal wall contact and friction.

EndoMAXX - Designed with Anti-Migration StrutsAccording to the aforementioned study by Dua et al., “stent migration occurred in 4 of 35 patients (11%)” and “all stent migrations were distal.”1 It is to be noted that not all migration is bad. When a patient’s tumor shrinks from cancer treatment, the stent has nothing to compress against and can migrate distally.

The EndoMAXX is designed with both proximal and distal metal sutures to provide a means for repositioning of the stent post placement and removal if necessary. This can be accomplished by using rat-tooth forceps and grasping the gold metal bead in the suture loop at the proximal end of the stent. Then carefully, using a purse-string effect, the proximal end of the stent is released from contact with the esophageal wall and traction is applied as it is removed.

No surgery is free of complications, but choosing products designed to decrease their incidence may result in better patient outcomes. Merit’s esophageal stents have a number of key features that address common concerns associated with esophageal stent placement, all while maintaining luminal patency.

Helping You Understand Esophageal Cancer

April is Esophageal Cancer Awareness Month

Across the nation, Americans are recognizing April as Esophageal Cancer Awareness Month—a full 30 days dedicated to learning more about the disease, signs and symptoms of it, and steps individuals can take to reduce their risk.

This year alone, it’s estimated there will be more than 19,000 new esophageal cancer cases diagnosed and more than 15,000 deaths from the disease in the United States.

To help this patient population, our goal at Merit Medical is to not only provide the tools physicians need to treat and improve outcomes for individuals with esophageal cancer but also share knowledge and increase awareness surrounding the disease.

Use the following infographics and resources to inform yourself and prepare for a discussion with your doctor about your own personal risk.


Esophageal Cancer

Esophageal cancer is cancer found in the esophagus—the hollow, muscular tube in your body that carries food and liquid from the throat to the stomach.


Although a rare condition, esophageal cancer has an average five-year survival rate of approximately 20%.

Risk factors for developing esophageal cancer include the following:

Old Age Increases the Risk of Esophageal Cancer
Acid reflux or GERD can increase your risk of esophageal cancer
Obesity increases your cancer risk
Too much processed meat creates a higher risk of cancer
Smoking - Cause of Cancer - Merit Medical Endoscopy

If you’re experiencing heartburn that’s severe or frequent, it’s important you talk with your doctor. The longer it continues, it can damage the inner lining of the esophagus, leading to a condition called Barrett’s esophagus, which increases your risk of esophageal cancer.

Find help to stop smoking and support to reduce alcohol consumption.

Learn more about other risk factors, including how men are three times as likely as women to suffer from esophageal cancer.


Types of Esophageal Cancer and Where They Occur

Esophageal cancer is most common in two formssquamous cell carcinoma and adenocarcinoma. Squamous cell carcinoma typically affects the upper and middle esophagus, whereas adenocarcinoma is commonly found in the lower esophagus near the stomach and is believed to be related to stomach acid exposure. Learn about other forms of esophageal cancer.

Adenocarcinoma is the most common type of esophageal cancer among Caucasian people, whereas squamous cell carcinoma is more common among African Americans. In comparison, American Indian/Alaska Natives, Hispanics, and Asians/Pacific Islanders have lower rates of esophageal cancer, respectively.


Risks and Warnings

Esophageal cancer can be difficult to treat because individuals don’t usually experience symptoms until the disease is advanced. Esophageal cancer usually doesn’t cause symptoms in its early stages.

As it progresses, symptoms can include:

  • Difficulty swallowing, can be painful
  • Hoarse voice
  • Indigestion or heartburn
  • Weight loss
  • Persistent cough
  • Vomiting

Some risk factors for esophageal cancer can’t be avoided, such as genetics or age. However, there are many lifestyle changes that can help you reduce your risk, such as avoiding tobacco and treating acid reflux:

Recognizing Lung Cancer Awareness Month

November is Lung Cancer Awareness Month, an important time for us at Merit Medical. As a patient-centric healthcare company, it is our goal to not only provide the tools physicians need to treat and improve outcomes for lung cancer patients but also to share knowledge and increase awareness surrounding the disease.


Lung cancer is a type of cancer that begins in the lungs. It is the leading cause of cancer deaths worldwide.1 Among women in the US, it has surpassed breast cancer, becoming the leading cause of cancer deaths nationally.2

There are different kinds of lung cancer, but the two main types are non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC).3

Main Types of Lung Cancer - Non-Small Cell and Small Cell Lung Cancer - Merit Medical

Learn more about NSCLC, SCLC, and other types of lung tumors here.


It is unknown what causes every case of lung cancer, but there are known risk factors.


Smoking - Cause of Cancer - Merit Medical Endoscopy

Smoking is the leading cause of lung cancer, resulting in about 80% of lung cancer deaths. Although smoking is the strongest risk factor, it can also interact with other factors or not be the cause at all.


Exposure to Cancer-Causing Chemicals - Causes of Cancer - Merit Medical Endoscopy

Many people who develop lung cancer are smokers or former smokers, whereas others have never smoked at all. Lung cancer in non-smokers can be caused by exposure to different substances, such as radon, secondhand smoke, air pollution, asbestos, diesel exhaust, and other chemicals. People with a family history of lung cancer are also at an increased risk.

A small percentage of people develop lung cancer who have no known risk factors. This may happen with no outside cause or may be due to factors we have not found yet.

Learn more about lung cancer risk factors as well as gene changes that may lead to the disease.


In the early stages, lung cancer typically does not cause any signs and symptoms. In the advanced stages, common signs and symptoms of lung cancer can include:

  • A new, persistent cough
  • New onset of wheezing
  • Coughing up blood or rust-colored phlegm
  • Shortness of breath
  • Chest pain, especially when breathing deeply, laughing, or coughing
  • Hoarse voice
  • Weight loss without trying
  • Loss of appetite
  • Fatigue
  • Fluid in the chest
  • Persistent infections, such as bronchitis and pneumonia
  • Cancer spreading to other parts of the body (This can cause other signs and symptoms, such as headache, nausea, pain, etc., depending on which organ is affected.)

Only 16% of lung cancer cases are diagnosed at an early stage, and more than half of people with lung cancer die within one year of diagnosis.2 If you are at an increased risk of lung cancer, talk to your doctor about lung cancer screening options. Early detection can make a difference. The five-year survival rate for lung cancer is 56% for cases detected when the disease is still localized within the lungs.2 However, these rates decrease dramatically to only 5% when tumors have spread to other organs.2

AEROmini® Tracheobronchial Stent

AEROmini - Stent Group

Elation® Pulmonary Balloon Dilator


AEROmini® Now Offers Smallest Self-Expanding Nitinol Stents with Through-the-Scope Options

Merit Medical is committed to finding new ways to approach challenging procedures. We accomplish this by transforming customer needs into innovative products that improve the lives of patients. Applying this approach, our Merit Medical Endotek® team—a division committed to next-generation, non-vascular stent technology—sought out valuable physician feedback and used it to develop new and improved AEROmini Tracheobronchial Stents. This exciting line extension offers the smallest self-expanding nitinol stents on the market. With both through-the-scope and over-the-wire deployment options, interventional pulmonologists and surgeons can reach small, distal airways deep within the lung that were previously considered untreatable.

AEROmini Tracheobronchial Stents are indicated for use in the treatment of tracheobronchial strictures produced by malignant neoplasms. Now with through-the-scope capabilities, physicians can deploy AEROmini stents through a 2.8 mm or larger working channel of a therapeutic bronchoscope with direct visualization of the affected area without the need for fluoroscopy. The new through-the-scope AEROmini stents are available in 6-mm diameter and 10-mm and 15-mm lengths, allowing physicians to reach tortuous distal airways with control and precision.

In addition to through-the-scope deployment, the new AEROmini line extension offers smaller, over-the-wire stents specifically designed for physicians treating patients with shorter strictures or those who insist on accurate stent placement without occluding adjacent airways. Available in 8-mm through 14-mm diameters and a 10-mm length, over-the-wire AEROmini stents expand the options for difficult strictures.

Customers can expect the same trusted features and benefits from the new line extension as they have from original AERO® and AEROmini stents. For example, the AERO technology has virtually no foreshortening or elongation of the stents. All stents are fully covered and hydrophilically coated to prevent ingrowth and mucus plugging. Proprietary anti-migration struts decrease stent migration without the potential complications associated with tissue ingrowth. In addition, the through-the-scope suture knot and over-the-wire purse string design aid in stent repositioning and removal.

For over a decade, Merit Medical Endotek has been committed to innovating for the pulmonary space. By listening to our customers, we consistently dedicate our internal research and development team to delivering innovative products that expand treatment options available to physicians and that can ultimately lead to better patient outcomes. With the new AEROmini line extension, we have kept this promise, designing cutting-edge technology that improves the lives of patients.
