Glossary of Lung Cancer Terms

A

  • Ablation – A treatment that destroys cancerous tissue, often using heat (radiofrequency ablation) or cold (cryotherapy).
  • Adjuvant therapy – Additional cancer treatment given after the primary treatment to lower the risk of recurrence, such as chemotherapy or radiation after surgery.
  • Adenocarcinoma – The most common type of non-small cell lung cancer (NSCLC), often found in the outer parts of the lungs.
  • ALK (Anaplastic Lymphoma Kinase) – A gene that can mutate and drive lung cancer growth, targeted by specific therapies like ALK inhibitors.

B

  • Biopsy – A procedure to remove a small sample of tissue for examination under a microscope to check for cancer.
  • Biomarker testing – A lab test that looks for specific gene mutations, proteins, or other molecules in cancer cells to determine the best treatment.
  • Bronchoscopy – A procedure that uses a thin, flexible tube with a camera to examine the airways and collect tissue samples.

C

  • Chemotherapy – The use of drugs to kill or slow the growth of cancer cells, often given in cycles.
  • CT scan (Computed Tomography scan) – A detailed imaging technique used to detect lung tumors or track cancer progression.

D

  • Driver mutation – A genetic change in a cancer cell that helps it grow and spread, targeted by specific drugs.
  • Durable response – A long-lasting effect of a cancer treatment, particularly in immunotherapy.

E

  • EGFR (Epidermal Growth Factor Receptor) – A gene that can be mutated in lung cancer, leading to uncontrolled cell growth. Targeted therapies exist for EGFR mutations.
  • Endobronchial ultrasound (EBUS) – A specialized type of bronchoscopy that uses ultrasound to help guide biopsies of lymph nodes or lung masses.

F

  • First-line therapy – The initial treatment given for lung cancer, which may include surgery, chemotherapy, targeted therapy, or immunotherapy.
  • Fluoroscopy – A real-time X-ray imaging technique used to guide procedures such as biopsies.

G

  • Genomic testing – Another term for biomarker testing, used to identify mutations that may be treated with targeted therapies.

H

  • Histology – The study of tissue samples under a microscope to determine the type of lung cancer.

I

  • Immunotherapy – A type of treatment that helps the body’s immune system recognize and fight cancer, often using checkpoint inhibitors.
  • Interstitial lung disease (ILD) – A potential side effect of some lung cancer treatments, causing lung inflammation and scarring.

J

  • Jacqueline’s Law – (Not a real law, but could represent patient advocacy efforts for lung cancer awareness and funding).

K

  • KRAS (Kirsten Rat Sarcoma Virus) – A common gene mutation in lung cancer that can now be treated with targeted therapies.

L

  • Lobectomy – Surgical removal of a lobe of the lung, often used in early-stage lung cancer.
  • Lung nodule – A small mass in the lung that may be benign or cancerous, often detected by imaging.

M

  • Metastasis – The spread of cancer from the lung to other parts of the body, such as the brain, liver, or bones.
  • MRI (Magnetic Resonance Imaging) – A detailed imaging technique used to check for lung cancer spread, especially to the brain.
  • Mutation – A change in a gene that may lead to cancer development or influence treatment options.

N

  • NED (No Evidence of Disease) – A term used when scans show no visible cancer after treatment.
  • Non-small cell lung cancer (NSCLC) – The most common type of lung cancer, including adenocarcinoma, squamous cell carcinoma, and large cell carcinoma.

O

  • Oncogene – A mutated gene that drives cancer growth, often targeted by specific treatments.
  • Opdivo (nivolumab) – A type of immunotherapy used to treat lung cancer.

P

  • Palliative care – Supportive care focused on improving quality of life for patients with lung cancer, regardless of stage.
  • PD-L1 (Programmed Death-Ligand 1) – A protein that some lung cancer cells express to evade the immune system. Higher levels may indicate suitability for immunotherapy.
  • PET scan (Positron Emission Tomography scan) – An imaging test that helps detect cancer spread using a radioactive sugar.
  • Precision medicine – A treatment approach that tailors therapy based on individual genetic mutations and biomarkers.

Q

  • QoL (Quality of Life) – A term used to describe a patient’s overall well-being, including physical, emotional, and social health.

R

  • Radiation therapy – The use of high-energy rays to kill cancer cells, often used in combination with other treatments.
  • Resection – Surgical removal of part or all of a tumor.

S

  • Small cell lung cancer (SCLC) – A fast-growing and aggressive type of lung cancer that often responds well to chemotherapy initially.
  • Stage – A classification system (Stage I to IV) that describes how far lung cancer has spread.
  • Survivorship – The phase of life after lung cancer treatment, which may include monitoring and managing side effects.

T

  • Targeted therapy – Drugs designed to attack specific genetic mutations in cancer cells, such as EGFR or ALK inhibitors.
  • Thoracentesis – A procedure to remove fluid from around the lungs, often done to relieve symptoms in lung cancer patients.
  • Tumor board – A group of doctors from different specialties who discuss the best treatment options for a lung cancer patient.

U

  • USPSTF (U.S. Preventive Services Task Force) – An organization that provides lung cancer screening recommendations.

V

  • VATS (Video-Assisted Thoracoscopic Surgery) – A minimally invasive lung cancer surgery.

W

  • Watchful waiting – A strategy of monitoring a lung nodule over time instead of treating it immediately.

X

  • X-ray – A common imaging test used to detect lung abnormalities, but less detailed than CT or PET scans.

Y

  • Yield (Diagnostic Yield) – The likelihood that a test will provide useful diagnostic information.

Z

  • Zepzelca (lurbinectedin) – A drug used for treating small cell lung cancer.
