Lymphomas Flashcards
Compare Hodgkin's lymphoma and non-Hodgkin's lymphomas in terms of clinical manifestations, staging, and nursing and collaborative management.
Definition of Lymphomas
Malignant neoplasms originating in the bone marrow and lymphatic structures resulting in the proliferation of lymphocytes.
Definition of Hodgkin’s lymphoma (aka Hodgkin’s disease)
A malignant condition characterized by proliferation of abnormal giant, multinucleated cells, called Reed-Sternberg cells, which are located in lymph nodes.
Pathophysiology of Hodgkin’s lymphoma
Diagnosis &
Progression
the normal structure of lymph nodes is destroyed by the hyperplasia of monocytes and macrophages.
Diagnostic: presence of Reed-Sternberg cells in lymph node biobsy.
Progression: usually originates in lymph nodes, infiltrates other organs, esp lungs, spleen, and liver. Staged 1-4 (A or B: presence or absence of significant systemic symptoms- fever, night sweats, weight loss).
Clinical Manifestations of Hodgkin’s lymphoma
Onset is gradual, initially enlargement of cervical, axillary or inguinal lymph nodes; a mediastinal node mass is 2nd most common. discrete nodes that remain movable and nontender.
weight loss, fatigue, weakness, fever, chills, tachycardia or night sweats
B- symptoms: fever, night sweats, and weight loss- worse prognosis. Alcohol causes pain at site
Clinical Manifestations of Non-hodgkins lymphoma
painless lymph node enlargement with s/s dependent on area of disease. B symptoms only 40% common (in Hodgkins its common)
Collaborative care for lymphomas
- localized radiation
- combination chemotherapy with localized radiation
- high-dose combination chemotherapy with localized radiation
What are NHLs (non-Hodgkin’s lymphomas)
heterogeneous group of malignant neoplasms of primarily B- T-cell origin affecting all ages. It is the most commonly occuring hematologic cancer and the fifth leading cause of cancer death.
Diagnostic studies for NHL
Staging 1-4 (similar to Hodgkins L.) NHL is more often in extranodal sites: MRIs must be done to rule out CNS or bone marrow infiltration or a barium enema, upper endoscopy or CT to visualize suspected GI involvement.
What is a Multiple Myeloma (plasma cell myeloma)?
A condition in which neoplastic plasma cells infiltrate the bone marrow and destroy bone.
The malignant Plasma cells (activated B cells) produce abnormal and excessive amounts of immunoglobulins (antibodies) called myeloma protein. Production of excessive cytokines –role in bone destruction
Clinical Manifestations of Multiple Myelomas
- skeletal pain is most common
- symptoms develop slowly
- fractures
- fatigue
- bone degeneration–calcium loss—hypercalcemia
Diagnostic studies for Multiple Myelomas
labs (calcium, high protein levels, H/H, CBC, elevated creatinine, Beta microglobulin and albumin)
Bence Jones proteins from the myeloma cell detected in urine. Monoclonal (M) antibody protein found in blood and urine.
Nsg management for Multiple Myelomas
- maintain adequate hydration (to minimize problems from hypercalcemia)
- move pt carefully
- ambulate as tol
- pain management
- teach pt. and fam about remissions and exacerbations, and need for hospitalization during acute episodes.
Characteristics of Benign Neoplasms
- usually encapsulated
- normally differentiated
- absence of metastasis
- recurrence is rare
- slight vascularity
- expansive mode of growth
- cell characteristics are fairly normal, similar to parent cells
Characteristics of Malignant Tumors
-rarely encapsulated
-are poorly differentiated
–capable of metastasizing
–Recurrence is possible
–moderate to marked vascularity
–infiltrative and expansive mode of growth
Cell characteristics are abnormal, become more unlike parent cells
examples of malignant tumors
Carcinoma (skin and tissues lining internal organs)
Sarcoma (bone, conn. and supportive tissue)
Leukemia (starts in blood)
Lymphoma & myeloma (immune system)
CNS (brain and spinal cord)
