Van Cleave MSN, ACNP-CS, CS, AOCN Acute Care Nurse Practitioner The Mount Sinai Medical Center of New York City Doctoral Student, Yale University School of Nursing Mr. L. is a 65 year old gentleman Has enlarged cervical lymph node Surgeons remove lymph node Pathology shows small lymphocytic lymphoma Doctor recommends to watch and wait Non-Hodgkin s Lymphoma Mr. D is a 65 year old Has enlarged cervical lymph node Surgeons remove lymph node Shows Diffuse Large B-cell B Lymphoma Oncologist recommends R-CHOP R Non-Hodgkin s Lymphomas Why are these two patients treated differently? Normal Maturation of Lymphocytes Differentiation of healthy lymphocytes Stem cells in bone marrow Rearrangement of genes to form immunoglobulin or T-T cell receptors Exposure to antigen Large proliferating cells Hypermutation improves antigen specificity Hennessy et al., Lancet Oncology, 2004 Non-Hodgkin s Lymphoma Differentiation of healthy lymphocytes Lymphocyte differentiation and maturation Antigen profile determines B or T cell B Cell: CD19, CD20, CD22, CD40, CD45, CD 79a T Cell: CD3, CD4, CD5, CD8, CD 45 Hennessy et al., Lancet Oncology,

9 Summary Slide Not Available Non-Hodgkin s Lymphoma is a diagnosis comprising different types of diseases Low grade lymphoma has longer average survival but decreased response to Aggressive lymphoma has greater response to but shorter average survival Summary Diffuse large B-cell B lymphoma is the most common aggressive lymphoma and most common subtype of NHL First line treatment for diffuse large B-cell B lymphoma is R-CHOP R Approximately 40% can patients w/ diffuse large B-cell B lymphoma can be cured with Nursing Implications R-CHOP Chemotherapy Adverse Effects Doxorubicin/Vincristine strong vesicants Nausea/Vomiting Myelosuppression Cardiotoxicity Neuropathy Anaphylactic reactions Hemorrhagic cystitis Alopecia Chu & DeVita, Jr. (2003) Nursing Implications: R-CHOPR Generally outpatient except for co- morbid conditions or concern for risk for tumor lysis syndrome in setting of bulky disease Assess patient for adequate vascular access in setting of strong vesicants Evaluate cardiac left ventricular ejection fraction prior to initiating Evaluate for need for hematological growth factor support Use with caution in setting of liver dysfunction Fischer et al (2003), Chu & DeVita, Jr. (2003), Pfreundschuh et al (2004) Why did one patient receive and the other patient did not receive? Why did the doctor Watch and wait for recommend asymptomatic Mr. D indolent lymphoma (aggressive Chemotherapy lymphoma) and none aggressive lymphoma for Mr. L (indolent lymphoma)? 9
