Treatment-related risk factors
◦ Chemotherapy
◦ Biotherapy
◦ Radiation
◦ therapy
◦ Infiltration of bone marrow by solid tumor
Patient-related

23. Disseminated intravascular coagulation (DIC)
involves an abnormal activation of the clot
formation and fibrin mechanisms in the blood,
resulting in the consumption of coagulation factors
and platelets. Patients with DIC are at high risk for
thrombus formation, infarctions, and bleeding.
Syndrome of:
◦ Thrombus formation (clotting)
◦ Simultaneous Hemorrhage
Caused by over stimulation of normal coagulation
processes
24. Paradox of DIC: bleeding and clotting
Triggered by:
Intrinsic coagulation system activation (damage to blood
vessels)
◦ Transfusion reactions
◦ Endotoxins/Septicemia
◦ Sickle Cell Disease
◦ Malignant hypothermia
Extrinsic coagulation system activation (tissue injury)
◦ Obstetrical Conditions
◦ Extensive surgery
◦ Crush injuries
◦ Malignancies
25. Acute Promyelocytic Leukemia (APL)
◦ Procoagulant material release by granules of the immature
promyelocyte leads to initiate clotting cascade
◦ Occurs in 85% patients with APL
Solid Tumors (adenocarcinomas)
◦ Lung, pancreas, prostate, stomach, colon, ovary, gall bladder, breast,
kidney
Chemotherapy
◦ May induce DIC by damaging tumor, normal cells, or endothelium to
causes release procoagulant material
◦ Large tumor burden/large cell kill may release granule procoagulant
from dead cells into systemic circulation
Infection/sepsis
◦ Especially gram negative bacteria sepsis (release of endotoxin)
Hemolytic transfusion reactions
◦ Rupture of RBC’s and platelet aggregation, release platelet factors that
initiate clotting cascade
26. Acute DIC
◦ Medical emergency
Chronic DIC
◦ Produces coagulation abnormalities, with or without
clinical manifestations, that can be medically managed
◦ Most cases of chronic DIC due to underlying malignancy
27. Prothrombin Time (PT) Prolonged
Activated Partial Thromboplastin time
(APPT)
Prolonged

29. Early recognition & treatment of underlying
disorder

acidosis

30. Stop the micro clotting to maintain
perfusion & protect vital function

◦ Signs and symptoms of DIC (bleeding and/or clotting)
32. It is a metabolic disorder, most commonly develops
as a consequence of pathologic destruction of bone,
mediated by factors released by malignant cells
One of the most common, life-threatening
complications of malignancy
33. Parathyroid gland
◦ Production of parathyroid hormone (PTH)
◦ PTH is major hormone regulating extracellular Ca++
PTH increases Ca++ by 3 mechanisms:
◦ Direct action on bone
Stimulates activity of osteoclasts → breaks down bone
(bone resorption)
◦ Direct action on kidneys
Increases renal excretion of phosphate stimulates
reabsorption of Ca++
◦ Indirect action in gut
Enhances absorption of ingested Ca++ by stimulating
kidney conversion of vitamin D to biologically active form
34. Ca++ levels decrease below normal:
◦ Parathyroid stimulated to produce PTH
◦ Acts on bone and release of calcium (bone
resorption) into circulation
◦ Acts on kidneys leads increase renal secretion of
phosphorous and stimulates reabsorption of
Ca++
◦ Acts indirectly gut and enhance absorption Ca++
Ca++ levels increase above normal:
◦ Kidneys increase excretion of calcium
35. Bone stores: 99% of body’s calcium
Serum calcium: 1% circulates in serum,
divided into fractions:
◦ 50% is free ionized calcium
Only type that is biologically active
◦ 40% is bound to protein
Mostly albumin, but also globulin &
paraproteins
◦ 10% forms serum complexes with anions
Bicarbonate, phosphate, & citrate
36. Total calcium =
◦ Ionized calcium + protein-bound calcium
Used to “infer” the fraction of ionized calcium
The result is usually accurate, EXCEPT when serum
albumin is low
If albumin < 3.5 – 5.5 g/dL, results in:
◦ ↓in the fraction of protein-bound calcium
◦ ↑ in the ionized free calcium
Ionized calcium more accurately reflects true serum
calcium levels
37. Tumor-induced bone breakdown releasing Ca++
into bloodstream
Tumor secretion of a parathyroid hormone-related
protein (PTHrP)
◦ Squamous cell tumors: Lung, breast, prostate, head & neck,
esophagus, kidney
◦ Non-Hodgkin lymphoma, chronic myeloid leukemia (blast
phase), adult T-cell leukemia - lymphoma
Tumor production of 1,25-dihydroxyvitamin D
(calcitrol)
38. Corrected total serum calcium (TSC) needs to be
calculated if albumin is low
Corrected Total Serum Calcium (mg/dl) = Measured
serum Ca++ + (4.0 – serum albumin g/dl) X 0.8
**Normal Serum Ca++ = 8.5 – 10.5 ml/dl
39. Reflect direct depressive effects ↑ serum Ca++
exerts on:
◦ Excitability of nerve tissue
◦ Contractility of cardiac, smooth, skeletal muscles
Signs & symptoms:

Mobilization
Dietary recommendations
◦ Maintain salt intake
◦ Dietary calcium restrictions
not necessary
Medications to avoid
◦ Thiazide diuretics (↓ renal
excretion Ca ++)
◦ NSAIDS, H2 receptor antagonists
(inhibit renal blood flow)
◦ Vitamins A & D (increase bone
resorption)
◦ Parenteral/enteral solutions with
calcium
Corticosteroids
◦ Therapy of choice multiple
myeloma or lymphomas
Inhibits vitamin D conversion to
calcitriol
41. Recognize early signs & symptoms
Careful monitoring of patients taking:

states)

59. Superior vena cava syndrome (SVCS) occurs in patients
with lung cancer or cancers of the mediastinum when the
tumor or enlarged lymph nodes block circulation in the
vena cava. This results in edema of the head, neck, and
arms.
Obstruction of blood flow through the superior vena
cava (SVC)
Obstruction leads to venous return from head, neck,
upper arms, upper thorax impaired
