I work on a medical oncology floor at a large hospital. Our patients are either solid tumor (e.g., lung, breast, pancreatic CA) or hematological (e.g., leukemia, some lymphomas). We don't have GYN-onc on our floor.
Anyway, patients are generally there either for (a) treatment that requires in-patient status (chemo over several days, or close monitoring), (b) symptom management (pain, nausea/vomiting, fevers), or in some instances (c) previous cancer history and the hospital wasn't sure where else to place them.
Work load is similar to other med-surg type floors but our patients tend to be a little more critical. After chemo, your blood counts drop and immune system is compromised; many are very susceptible to infection/sepsis. Common transfers to/from ICU. We hang a lot of blood products. Some patients are up ad lib; others are "totals". Age range is around 19 and up. Many patients are repeat visitors. At end-stage of their disease many patients are discharged on hospice and some die on our floor.
There is a fair amount of variety as far as clinical skills used: around 75% have central lines, some trachs, G tubes, NG tubes, TPN, and chemo (obviously) and the precautions that go along with it.
Hope this helps and good luck.
