My neice was just diagnosed with lymphoblastic lymphoma stage 4....Last week this time none of us would imagine that she had anything like that. Couple of weeks ago she started with a cold and the cough got worse everyday. Doctor prescribed an x-ray and they found a mediastinal mass as big as a small football. One of her supraclavicular lymph nodes was enlarged so they took a biopsy...result positive. Doctors have started steroid treatment to shrink the mass and are starting the chemo in 5 days....Our whole family is devastated cause my neice is the most beautiful, lively, friendly person....she is so full of life. Can someone give me an input about the prognosis?  Did anyone have a similar experience around the same age group and stage?
