Hospital-based study on demographic, hematological, and biochemical profile of lung cancer patients.

Abstract

Lung cancer is considered as the most commonly diagnosed cancer. It is the leading cause of cancer-related mortality. Smoking and environmental pollutants act as important risk factors in majority of lung cancer cases (80%-90%). This is a hospital-based study carried on in lung cancer patients of North India. Demographic profile of lung cancer patients was recorded. Hematological and biochemical profiles of lung cancer patients and healthy controls were compared. Highest proportion of lung cancer was found in the age group of 46-60 years. Lung cancer was seen in highest number in male gender (76.63%) and also in those patients belonging to the rural category (84.58%). In this study, only 3.98% lung cancer patients having the past history of cancer and 5.47% showing the family history of cancer. Significant differences were found in weight and body mass index (BMI) of lung cancer patients when compared to healthy control (P < 0.0001). Hemoglobin (Hb) was found lower in lung cancer patients as compared with healthy controls. Significant difference was also observed in Hb levels of these two groups (P < 0.000). The serum protein level was lower in lung cancer patients than healthy controls. A significant difference was also observed in the protein levels of these two groups (P < 0.0001). Serum alkaline phosphatase (ALP) levels were higher in lung cancer patients in comparison to healthy controls. A significant difference was also observed in serum ALP levels in lung cancer patients as compared with healthy controls (P < 0.0001). Significant difference between BMI, Hb, serum albumin, and total protein was found in this study. These biomarkers may be helpful in the diagnosis of lung cancer at early stage and also in the follow-up assessment of the effects of treatment.
