ANSWERS
the risk for significant bone marrow suppression (8) - ANSWER>>advanced age
(>65),poor nutritional status, preexisting autoimmune disease, DM, GI
disorders, liver disease, or hematopoietic disease, and substance abuse.
Cancer-induced bone marrow suppression (3) - ANSWER>>a) dysfunctional
hematopoietic cell within the bone marrow, b) bone marrow infiltration with
tumor c)general exhaustion of bone marrow reserves
solid tumor malignancies with the highest propensity to infiltrate the bone
marrow in the course of metastasis - ANSWER>>melanoma, cancer of the
breast, lung, kidney and prostate
Nitrosoureas (Carmustine, Lomustine) - ANSWER>>affect the pluripotent stem
cell (affecting all cell lines/cell cycle nonspecific agent) use for glioblastoma
multiforme
severe myelosuppression may last up to 85 days, nadir of carmustine occurs in
26-60 days
Radiation induced bone marrow suppression occurs when (2) - ANSWER>>1.
treatment field involves marrow producing tissue or with dose greater than 15
Gy
CD 4 counts < 500/mm3 - ANSWER>>significant risk factor for oopotunisitic
infections
Cyclosphosphamide - myelosuppression risk - ANSWER>>moderate
Paclitaxel - myelosuppression risk - ANSWER>>moderate
,Doxorubicin (Adriamycin) - myelosuppression risk - ANSWER>>alkylating agnet,
may produce severe myelosuppression, the duration only about 21 days
Myelosupression secondary to radiation therapy peaks at - ANSWER>>week 3
Suppression may occur in all cell lines simultaneously rather than sequentially
as seen with chemotherapy
The recovery period also may be less predictable.
