Pleomorphic Pulmonary Carcinoma

My father recently got his lung cancer biopsy result back and the pathologist is saying its lung cancer with pleomorphic features. Most likely pleomorphic pulmonary carcinoma, anyone been through this diagnosis before or know anyone thats been diagnose with this lung cancer cell type? Its tough finding any stories of people getting through this online. I only know that its a pretty rare form of non small cell lung cancer. Any advice on how I can help my father get through this?
