Question:
First course treatment--Heme & Lymphoid Neoplasms: What is first course of treatment when a patient received multiple different chemotherapy regimens before a complete remission for diffuse large B-cell lymphoma was achieved?
Discussion:
The patient was initially treated with involved field radiation and R-CHOP. The patient still had residual disease and the treatment was changed to RICE. Following RICE, there was still residual disease and the patient underwent another unspecified chemotherapy treatment. The patient was then transferred to a transplant center for pre-transplant chemotherapy and a bone marrow transplant. The patient achieved a complete response after transplant.
Should the R-CHOP and radiation be the first course treatment in a case like this, or would first course treatment include all chemotherapy and the transplant?
Answer:
For hard-to-treat diseases such as DLBCL, the treatment plan outlined prior to treatment beginning may indicate, "The first course of treatment will be radiation and R-CHOP. If the R-CHOP does not achieve remission, we will use RICE." In other words, the first course treatment plan includes a second round of chemotherapy if the patient has not achieved a complete response after the R-CHOP and radiation. If the treatment plan was documented like this for the patient, the first course treatment includes R-CHOP, involved field radiation and RICE.
However, if there is no initial treatment plan in the medical record, all treatment provided after the date when "residual disease" or "failed to achieve remission" is documented in the medical record is either second or a subsequent course of therapy.
