Expanding Lung Cancer Treatment Options with Proton Therapy

proton therapy lung cancer awarenessThe National Cancer Institute predicts an estimated 228,150 new cases of lung cancer will be diagnosed in 2019, accounting for 12.9% of all new cancer cases for the year. Lung cancer is identified as two main types: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC).

Non-small cell lung cancer is the most common form of lung cancer and accounts for 85% of lung cancer cases. Small cell lung cancer accounts for 10% to 15% of cases and generally grows more quickly, and is likely to spread to other parts of the body.

Proton Therapy, Power and Precision

Proton therapy has ushered in a new form of treatment for specific patients with lung cancer.

Many patients with lung cancer receive radiation treatment for early-stage disease. A highly focused type of radiation called stereotactic body radiation therapy can provide excellent outcomes. Proton therapy may be an appropriate option for some patients, often those with Stage III lung cancer or who need radiation after surgery.

Proton therapy can reduce or avoid radiation to the healthy, normal lung tissues and esophagus in certain cases. This may reduce the risks of swallowing difficulty or heart and lung problems after treatment.

Patients may also be eligible to participate in an ongoing national clinical trial comparing X-ray-based radiation and proton therapy to determine if proton therapy may improve outcomes or reduce risks of treatment.

Genomic Testing for Lung Cancer: What Does it Mean for You?

Lung Cancer Awareness MonthYou may be surprised to learn that lung cancer is the leading cause of cancer deaths in both men and women in the United States.  However, in the past few years, tremendous progress has been made leading to improved outcomes for patients with lung cancer.  According to the Centers for Disease Control and Prevention, genomics is “the study of all the genes in a person, as well as the interactions of those genes with each other and a person’s environment.”  While 99.9% of everyone’s genetic makeup is identical, the difference in the remaining 0.1% helps inform researchers about disease. For patients with certain subtypes of lung cancer, we have now made genomic testing of tumors a routine part of care.  Understanding that each person has a unique genetic makeup allows for individualized treatment for patients with specific mutations in their tumor tissues.

Lung cancer is broadly divided into two types: non-small cell lung cancer and small cell lung cancer.  Approximately 85% of lung cancers are of the non-small cell lung cancer category, which consists of three major subtypes: adenocarcinoma, squamous cell carcinoma and large cell carcinoma.

Adenocarcinoma accounts for nearly 50% of all non-small cell lung cancers and has had an increasing rate of incidence in the United States over the past few years. During the same time, we have learned a lot about the biology of lung cancer overall. As a result, sophisticated tests are now available to identify specific mutations in tumors of patients with adenocarcinoma of the lung.  For example:

  1. A gene called epidermal growth factor receptor (EGFR) is mutated in nearly 15% of patients with adenocarcinoma.  After years of research, we now know that treatment for these patients involves an orally administered targeted drug, versus combination chemotherapy. These novel treatments result in significant improvement of symptoms, disease control and survival.
  2. Through other research, we now know that another group of patients with adenocarcinoma carries a mutation in a gene called ALK.  For these patients, an FDA-approved treatment option named crizotinib is used, which has been found to provide great benefits to these patients.

Since it has been identified that a person’s genetic makeup plays a significant role in not only understanding their overall health and disease occurrence, but also the ideal treatment method(s) they should receive, nowadays, almost every patient diagnosed with lung adenocarcinoma is genetically tested for specific mutations. The good thing about this test is that it can usually be performed from already collected specimens used to diagnose lung cancer, therefore eliminating the need for additional invasive procedures.

Highlights of this post

At the Winship Cancer Institute of Emory University, we have implemented a standardized molecular testing protocol for every patient diagnosed with lung adenocarcinoma.  As a result, in most circumstances, when an oncologist sees a patient for the first time, detailed molecular information is available on the tumor tissue, which helps inform treatment decisions.

Unfortunately, for certain mutations, there are currently no FDA-approved treatment options. Yet, as Georgia’s first and only National Cancer Institute –designated cancer center, Winship offers a number of innovative clinical trials for such patients, with the aim of identifying treatment options that provide the best likelihood of success.

Through research and clinical trials, investigators and physicians have discovered that understanding the genetic makeup of lung cancer patients is key. This knowledge allows for optimal, individualized treatment options that lead to overall improved outcomes for our patients.
