Indolent lung cancers--time for a paradigm shift: a review
1Department of Pulmonary Medicine and Allergy, Karolinska University, Stockholm, Sweden. gunnar.hillerdal@karolinska.se
Summary
Clinically unimportant lung cancers are more common than previously thought, challenging current medical paradigms. Further research into tumor doubling time is crucial for improved patient screening and treatment strategies.
Area of Science:
- Pulmonology
- Oncology
- Radiology
Background:
- Current medical understanding underestimates the prevalence of slow-growing, clinically insignificant lung cancers.
- Advancements in computed tomography (CT) scanning reveal a higher incidence of these tumors than previously acknowledged.
Purpose of the Study:
- To advocate for a paradigm shift in understanding lung cancer characteristics.
- To highlight the need for research into tumor behavior prediction for improved patient care.
Main Methods:
- Review of existing clinical paradigms and evidence regarding lung cancer growth rates.
- Analysis of the impact of widespread computed tomography (CT) screening on lung cancer detection.
Main Results:
- The increasing prevalence of CT screening makes the existence of numerous slow-growing lung cancers undeniable.
- Tumor doubling time is identified as a critical factor influencing patient survival.
Conclusions:
- A paradigm shift is necessary in lung cancer screening and clinical practice.
- Urgent research is required to develop methods for measuring tumor doubling time.
- Predicting cancer behavior (indolent vs. aggressive) will enable more personalized and effective patient treatment advice.

02:56Treatment Resistant Cancers
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

02:57Targeted Cancer Therapies
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

01:20Chronic Obstructive Pulmonary Disease-I: Introduction
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.
02:49Cancer Therapies
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

01:20COPD: Pathogenesis and Clinical Features
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
