Reason for Hospital Reason for Hospital AdmissionAdmission
• The patient was admitted to the hospital for reparative surgery of a fractured right hip due to a nonsyncopal fall.
• Shortly before the patient fractured his hip, he was diagnosed with metastatic RCC.
• A x-ray exam found metastatic lesions in the area of the fracture.
Medical/Health/Family Medical/Health/Family HistoryHistory
• Past medical history:– Stage IV RCC s/p 2 chemotherapy treatments– Type 2 diabetes with neuropathy– Hypertension– Hyperlipidemia– Peripheral vascular disease– Benign prostatic hyperplasia– Chronic kidney disease stage III
Medical/Health/Family HistoryMedical/Health/Family History
• Home medications:– Enalapril, Megace, metformin, Norco, Reglan,
iron, omeprazole, tamsulosin, fluoxetine
• Quit smoking 9 months prior to admission
• No history of alcohol or illicit drug abuse
• Poor appetite
• Family history positive for type 2 diabetes
Medical DiagnosisMedical Diagnosis• Pathologic fracture in the right femoral
neck 2° metastatic RCC
• Pathologic fracture in the right proximal humerus 2° metastatic RCC
• Acute-on-chronic renal failure
RCC DefinedRCC Defined• RCC:
– Most common form of kidney cancer– 14th most common form of cancer in US– Highly vascularized malignancies– Originates in lining of proximal convoluted
tubules – Termed metastatic RCC when its spreads
Pathophysiology Pathophysiology • RCC consists of various tumor groups:
– Clear cell, 60-70% – Papillary, 5-15%– Chromophobe, 5-10%– Oncocytic, 5-10%– Collecting duct, <1%
Symptoms/Clinical Symptoms/Clinical ManifestationsManifestations
• RCC often presents with symptoms unrelated to renal cancer.
• The 3 classical RCC symptoms include:– Abdominal pain, hematuria, palpable mass
• Metastatic RCC presents with:– Bone pain, pulmonary issues, adenopathy, GI
bleeds
EtiologyEtiology• Risk factors for RCC:
– Tobacco smoking– Obesity– Hypertension– Chemical exposure– Analgesic drug use– Hepatitis C infection– End-stage renal disease
Hypertension and Risk of Renal Cell Hypertension and Risk of Renal Cell Carcinoma Among White and Black Carcinoma Among White and Black
AmericansAmericans
• Purpose:– To determine the association between high blood
pressure and RCC risk for black and white Americans
• Methods:– 358 black and 843 white case participants– 519 black and 707 white control participants– HTN history and antihypertensive drugs reported– ORs and CI calculated utilizing unconditional logistic
regression • Adjusted for smoking, BMI, family history of RCC,
demographic characteristics
(Colt et al., 2011, p. 1-4)
Hypertension and Risk of Renal Cell Hypertension and Risk of Renal Cell Carcinoma Among White and Black Carcinoma Among White and Black
AmericansAmericans
• Results:– In study population, HTN doubled risk of RCC – Whites had lower incidence of developing
RCC (P=0.11)– RCC risk ↑ with passing years after initial dx
of HTN with an OR of 4.1 (CI=2.3-7.4) for blacks and an OR of 2.6 (CI=1.7-4.1) for whites (P for trend <0.001)
(Colt et al., 2011, p. 1, p. 4-5)
Hypertension and Risk of Renal Cell Hypertension and Risk of Renal Cell Carcinoma Among White and Black Carcinoma Among White and Black
AmericansAmericans
• Conclusion:– Among blacks and whites, HTN is a risk factor
for RCC.– Due to the increased prevalence of high blood
pressure in blacks than whites, HTN may explain the racial disparity of RCC incidence seen more commonly in the former rather than the latter group.
(Colt et al., 2011, p. 1, p. 5-7)
TreatmentTreatment• Treatment depends on:
– Type of RCC– Stage of RCC– Tissue or organs affected– Preexisting conditions or comorbidities– Nutritional status– Age
TreatmentTreatment• Surgical interventions:
– Nephron-sparing partial nephrectomy– Radical nephrectomy– Laparoscopic nephrectomy
TreatmentTreatment• Immunotherapy:
– Interleukin-2 – Interferon
• Tumor ablation therapy:– Cryoablation – Interstitial radio frequency
ablation
TreatmentTreatment• Targeted therapy:
– Sorafenib, pazopanib, sunitinib, everolimus
• Chemotherapy and radiotherapy
TreatmentTreatment• Treatment specific to patient:
– Repair of right femoral neck fracture• Right hip long stem hemiarthroplasty with cement
– Repair of right proximal humerus fracture• Intramedullary fixation
TreatmentTreatment• Medications:
– Amlodipine, cefazolin, enalapril, fluoxetine, heparin, insulin, Megace, omeprazole, pantoprazole
• Patient had received 2 chemotherapy treatments prior to admission
TreatmentTreatment• Drug-nutrient interactions:
– Fluoxetine — if taken with tryptophan supplements, can ↑ drug side effects
– Omeprazole — can ↓ calcium absorption by 61%; if taken with gingko and St. John’s wort, can ↓ drug effectiveness
(Pronsky & Crowe, 2010, p. 140, p. 260).
Nutrition InterventionNutrition Intervention• Interventions implemented to combat following
side effects associated with advanced cancer:– Nausea/vomiting– Weight loss– Early satiety– Anorexia– Xerostomia– Altered taste– Bloating – Constipation– Dysphagia
Fruit, Vegetables, Fibre and Micronutrients Fruit, Vegetables, Fibre and Micronutrients and Risk of US Renal Cell Carcinomaand Risk of US Renal Cell Carcinoma
• Purpose:– To determine if an association existed
between the risk of RCC and the intake of fruit, vegetables, fiber, and certain micronutrients
• Methods:– 323 case participants– 1,827 control participants– Questionnaires with dietary intake of
participants mailed to researchers for analysis
(Brock et al., 2011, p.1077-1078)
Fruit, Vegetables, Fibre and Micronutrients Fruit, Vegetables, Fibre and Micronutrients and Risk of US Renal Cell Carcinomaand Risk of US Renal Cell Carcinoma
• Results:– Intake of vegetables ↓ RCC risk
• (P for trend =0.002)
– Vegetable fiber associated with ↓ RCC risk• (P<0.001)
– Grain and fruit fiber had no association with ↓ RCC risk
– β-cryptoxanthin ↓ RCC risk• (P for trend =0.01)
– Lycopene nonsignificantly ↓ RCC risk(Brock et al., 2011, p.1077, p.1079)
Fruit, Vegetables, Fibre and Micronutrients Fruit, Vegetables, Fibre and Micronutrients and Risk of US Renal Cell Carcinomaand Risk of US Renal Cell Carcinoma
• Results cont.:– Association between RCC risk and intake of
vegetable fiber and β-cryptoxanthin stronger in those ≥65 years of age
