Rationale:
Spontaneous regression of non-small cell lung cancer is exceptionally rare.
Patient Concerns:
Treatment-related toxicity.
Diagnoses:
We report a case of a patient diagnosed with locally advanced non-small cell lung cancer.
Interventions:
The patient declined potentially curative treatment, and did not receive any anti-cancer treatment.
Outcomes:
He has survived more than two years since his initial diagnosis, maintaining his good performance status. Serial imaging with computed tomography scans showed tumour regression and near-complete resolution of his disease.
Lessons:
Spontaneous regression of non-small cell lung cancer, by virtue of its scarcity, has not been well-studied and is poorly understood. Further studies are required, in order to clarify the mechanisms by which spontaneous regression occurs, and possibly identify new targets for cancer treatment.

Multiple Regression
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...

Regression Analysis
In regression analysis, a regression equation is determined based on the line of best fit– a line that best fits the data points plotted in a graph. This line is also called the regression line. The algebraic equation for the regression line is called the regression equation. It is represented as:
