IASLC Open Comment Period On “Multidisciplinary Recommendations For Pathologic Assessment Of Lung Cancer Resection Specimens Following Neoadjuvant Therapy”

Denver, Colorado - The International Association for the Study of Lung Cancer (IASLC) today announces an open comment period for the “IASLC Multidisciplinary Recommendations for Pathologic Assessment of Lung Cancer Resection Specimens Following Neoadjuvant Therapy” paper. The paper has been made available here to provide an opportunity for public review of new draft recommendations. The open comment period runs from October 14 to November 7, 2019.

With the recent growing number of neoadjuvant therapy clinical trials for non-small cell lung cancer, there is a great need for standardization of specimen processing since major pathologic response (MPR) has consistently been shown to be an important prognostic indicator. The purpose of this paper is to outline detailed recommendations on how to process lung cancer resection specimens and to define pathologic complete response (pCR) including major pathologic response (MPR) and pathologic complete response (pCR) following neoadjuvant therapy.

“Currently there is no established guidance on how to process and evaluate resected lung cancer specimens following neoadjuvant therapy in the setting of clinical trials and clinical practice,” said Giorgio Scagliotti, past president of the IASLC and co-author of the paper. “There is also a lack of precise definitions on the degree of pathologic response, including MPR or pCR.”

The IASLC is making an effort to collect such data from existing and future clinical trials. These recommendations are intended as guidance for clinical trials, although it is hoped they can be viewed as suggestions for good clinical practice outside of clinical trials, to improve consistency of pathologic assessment of treatment response.

These recommendations were developed by the IASLC Pathology Committee in collaboration with an international multidisciplinary group of experts in medical oncology, thoracic surgery and radiology.

”We are crossing an exciting period of preclinical and clinical research around thoracic oncology. Targeted therapies and immunotherapy have greatly improved survival expectations in advanced disease and we believe they can equally generate benefit in the systemic therapy of earlier stages of the disease,” said Scagliotti. “Our initiative aims to use rigorous experimental conditions to analyze tissue specimens, collected in the context of already performed or ongoing neoadjuvant studies with targeted therapies and immunotherapy, to generate a diagnostic algorithm to be used in all subsequent studies in order to accelerate the scientific information about the clinical benefit produced by the neoadjuvant approach.”

About the International Association for the Study of Lung Cancer (IASLC)

The International Association for the Study of Lung Cancer (IASLC) is the only global organization dedicated solely to the study of lung cancer and other thoracic malignancies. Founded in 1974, the association's membership includes more than 7,500 lung cancer specialists across all disciplines in over 100 countries, forming a global network working together to conquer lung and thoracic cancers worldwide. The association also publishes[A1] the Journal of Thoracic Oncology, the primary educational and informational publication for topics relevant to the prevention, detection, diagnosis and treatment of all thoracic malignancies.
