A 40-year-old woman presents with isolated cervical LAD with no fever, night sweats, or weight loss. A lymph node biopsy is performed and histopathology reveals small lymphocytes and rare Reed-Sternberg cells. Staging is done with MRI and she is found to have disease limited to one cervical nodal group. How would one classify her disease and what would be her prognosis?

A. Follicular lymphoma with a prognosis of 5 to 10 years without treatment and 50 to 75% response to chemotherapy and radiation with complete remission

B. HD stage IA with 85 to 95% 5-year survival and high potential for cure

C. HD stage IIA with 85 to 95% 5-year survival and high potential for cure

D. HD stage IB with poorer prognosis than stage IA

E. Diffuse large B-cell lymphoma, which is rapidly fatal without treatment but highly responsive to chemotherapy
