Summary
Routine blood indices can identify lung cancer with high accuracy using artificial intelligence. This AI-driven approach offers a cost-effective screening tool, potentially reducing the need for more complex diagnostic methods.
Area of Science:
- Oncology
- Biomarkers
- Artificial Intelligence
Background:
- Liquid biopsies are sensitive but require specialized techniques.
- Routine blood tests are common, cost-effective, and easily accessible.
- Machine learning can identify complex patterns in medical data.
Purpose of the Study:
- To explore the association between lung cancer and routine blood indices.
- To develop a tool for identifying lung cancer using standard blood tests.
Main Methods:
- Random Forest machine learning algorithm used to build a predictive model.
- Model evaluated using ten-fold cross-validation and additional testing.
Main Results:
- A correlation was found between 19 routine blood indices and lung cancer.
- The model achieved 96.3% sensitivity, 94.97% specificity, and 95.7% accuracy in identifying lung cancer.
- Distinguished lung cancer from tuberculosis with high accuracy.
Conclusions:
- Lung cancer can be identified using a combination of 19 routine blood indices.
- Artificial intelligence can detect disease-index correlations, potentially replacing costly tests.
- Routine blood test combinations may also be linked to other diseases.

Certain organic substances change color in dilute solution when the hydronium ion concentration reaches a particular value. For example, phenolphthalein is a colorless substance in any aqueous solution with a hydronium ion concentration greater than 5.0 × 10−9 M (pH < 8.3). In more basic solutions where the hydronium ion concentration is less than 5.0 × 10−9 M (pH > 8.3), it is red or pink. Substances such as phenolphthalein, which can be used to determine the pH of a solution, are...

23.7K
For solutions containing mixtures of different cations, the identity of each cation can be determined by qualitative analysis. This technique involves a series of selective precipitations with different chemical reagents, each reaction producing a characteristic precipitate for a specific group of cations. Metal ions within a group are further separated by varying the pH, heating the mixture to redissolve a precipitate, or adding other reagents to form complex ions.
For instance, group IV...

Qualitative analysis is the process of identifying elements, ions, or compounds in an unknown sample. It is the first and most fundamental type of analysis based on the hierarchy of analytical goals. This hierarchy is significant as it provides a structured approach to scientific research, with qualitative analysis serving as the initial step, providing essential information before moving on to quantitative or other forms of analysis.

Cardiovascular diseases, encompassing a range of conditions, can significantly affect the heart's operations and the overall circulatory system. These conditions impair the heart's ability to pump blood, leading to a deficit in oxygen supply to crucial organs. Anomalies in the heart's electrical system, known as arrhythmias, can cause heartbeats to accelerate or slow down. Usually, heart rates increase during physical activity and decrease while resting or sleeping. However,...

Machines are complex structures consisting of movable, pin-connected multi-force members that work together to transmit forces. One example of a machine is the cutting plier, which is used to cut wires by applying forces to its handles. When equal and opposite forces are exerted on the handles of the cutting plier, they cause the cutting edges to come together and apply equal and opposite reaction forces on the wire, which are greater than the applied forces.

Blood studies are critical in the medical field, enabling healthcare professionals to assess a patient's health status accurately. This page will focus on two significant blood studies: Arterial Blood Gas (ABG) and Venous Blood Gas (VBG).
Arterial Blood Gas (ABG)
Arterial Blood Gas (ABG) studies are crucial for assessing the lungs' ability to supply oxygen and remove carbon dioxide, reflecting the patient's ventilation status. They also help understand the kidneys' capacity to...
