[|Human|] HiI had a VATS RUL lobectomy in August.  I just found out is was a cancerous tumour.  What is the difference between small cell and large cell lung cancer?  The report says it s a grade 2, well differentiated.  About 7 cm in size.  Solitary.Also states: scattered pigmented macrophages in the air spaces and emphysema.  What does all this mean in terms of survival and reoccurence?  Thank you, Coleen
[|AI|]  First, you did not mention whether you had small cell cancer or not. Both have different treatment algorithms and outcomes. Small cell is generally more aggressive. Also, I would like to know if they removed the nodes or not and if they were involved by tumor or not (this would be in the biopsy report). If they were removed and are negative and the margins of resection are negative for tumor (this would mean that the tumor has been completely removed) then you would be in the 2nd stage (stage IIA technically but high risk due to large tumor size). So, I would recommend that you get further chemotherapy to decrease your chances of recurrence. The prognosis is good, and you have a 70% chance of being cured.
