AACR Logo According to a study, categorizing non-small cell lung tumors by development patterns seemed to have a powerful prophetic value for measures of survival. Growth pattern implies to the tumor growth in association with standard lung tissue and blood vessels in the tumor. Apparently, tumors require these blood vessels to stay alive and study authors have been examining these patterns in an attempt to individualize therapy.

The experts have supposedly organized the tumors into three growth patterns namely destructive, alveolar and papillary. In destructive patterns, the tumor appeared to make its own microenvironment for further growth. In the alveolar pattern, the tumor utilizes the microenvironment of the lung to develop, and in the papillary pattern the standard lung tissue is said to be maintained in the attendance of a new microenvironment.

Peyman Sardari Nia, M.D., Ph.D., a postdoctoral fellow at the University of Antwerp in Belgium, and colleagues examined this categorization to observe if they apparently had predictive value in patients suffering from non-small cell lung cancer.

Sardari Nia commented, “The current management, treatment and prognosis of lung cancer is treatment based on tumor-node-metastasis staging. Unfortunately, tumor node metastasis does not account for survival differences in the same stage and does not provide information about the biology of the tumor.”

The study included around 432 patients who apparently had a full resection for primary non-small cell lung cancer. The study authors supposedly trailed the patients for around 50 months. As per the classifications sketched, about 71.1 percent appeared to have a destructive growth pattern, 13.9 percent seemed to have a papillary growth pattern and roughly 15 percent had an alveolar growth pattern.

Sardari Nia mentioned, “This biological classification provides explanations for survival differences at the same disease stage. Additionally, these growth patterns represent distinct biologic subtypes implying that different growth patterns might respond differently to the pallet of treatment modalities, paving the way for individualization of the patient’s treatment.”

These growth patterns could be self-governing predictors for by and large survival, disease-specific survival and disease-free survival. Patients with an alveolar growth pattern apparently had a 52 percent larger likelihood of a poor forecast for overall survival and an almost two-fold augmented threat for poorer disease-specific survival and for disease-free survival.

The study was presented at the AACR-IASLC Joint Conference on Molecular Origins of Lung Cancer.
