sclc and nsclc treated the same?????

In 01/10, my mother got a chest x-ray after a bout of bronchitis. For some reason, one of her kidneys was captured and a mass was found, however there was also a spot on her lung which they determined was scar tissue from a recent episode of pnemonia. The mass on her kidney was found to be renal carcinoma--which was completely removed in 05/10. During a follow-up appointment with the kidney doctor in 07/10, they told her she needed to see the oncologist again as they found something during her last blood test. When she followed up with the oncologist, he advised there was no report of anything in her blood. She was indignant, insisted he get the kidney doc on the phone. Well, kidney doc said he did not remember telling my mother this and she did not have any issues. My mother is quite the 70 year old spitfire and insisted on a ct scan of her entire body because she did not trust what she was being told. Well, turns out 'pnemonia' is the newest way to describe small cell carcinoma because when the scan was completed in 08/10, the small area noted in 01/10 was now spread throughout both her lungs and her lymph nodes. A biopsy was completed and on 09/22/2010, my mother was told she has small cell carcinoma of the lungs. After a PET scan, we were told there are no mets anywhere else, however her prognosis is 4 mos w/o chemo and 12 mos with chemo. Because I live across the country from my mother, I was not there for the diagnosis. The info given to me intially was that my mother had 'stage four adenocarcinoma, small cell carcinoma of the lungs.' Once I started looking at things online, I was confused by the staging relevant to type of cancer as well as 'adenocarcinoma' being routinely exchanged with the terminology of nsclc. I spoke with the oncologist and he stated that the biopsy was too small of a specimen to term small cell or non-small cell. Further, he stated that it is probably small cell because there are hormones present in the sample, but that the course of treatment would be the same regardless. Almost everything I am reading indicates this is not the case. My mom has had 2 chemo treatments of cisplatin and VP-16. She is to continue chemo every three weeks for a total of 8 rounds of chemo. She has her first ct scan today. I am trying to remain hopeful since there are no mets anywhere at this time. I am also considering spending a tremendous amount of money on Poly-MVA, so anyone with any insight into this supplement would be greatly appreciated.
