Health-related and sociodemographic factors associated with physical frailty among older cancer survivors.

OBJECTIVE: The purpose of this study was to examine factors associated with frailty in older cancer survivors. MATERIALS AND METHODS: This is a cross-sectional study using data from the National Social Health and Aging Project (NSHAP) Wave 2, and includes an in-home, nationally representative sample of community-dwelling adults ≥50 years and older from the United States. Frailty score was computed for each individual using a modified 4-point scale based on the phenotypic frailty. Ordinal logistic regression was used to characterize the association between health-related, sociodemographic factors and frailty. RESULTS: Among the 3377 participants, 461 were cancer survivors (answered "yes" to "ever have cancer other than skin cancer"). A final sample of 394 cancer survivors were included: 59 participants (16.1%) were frail, 219 participants were pre-frail (59.8%), and 88 participants were non-frail (24.0%). The univariate analyses showed increasing age (OR 1.48; CI 1.29-1.72; p-value <.001), comorbidities (OR 1.43; CI 1.25-1.64; p-value <.001), depression (OR 1.27; CI 1.19-1.35; p-value <.001) and low mobility (OR 1.55; CI 1.37-1.78; p-value <.001) were associated with frailty. Participants with high self-rated (good/very good/ excellent) physical health (OR 0.18; CI 0.11-0.30; p < .001) and mental health (OR 0.27; CI 0.15-0.50; p < .001) were less likely to be frail. In a multivariate model, frailty was associated with age, self-rated physical health, depression, ability to perform activities of daily living, and mobility (p < .05). CONCLUSION: The findings highlight the importance of incorporating geriatric assessment into cancer survivorship to prevent and delay the progression of frailty.

Incidence of postembolization syndrome after complete renal angioinfarction: a single-institution experience over four years.

OBJECTIVE: Renal angioinfarction (RAI) has been used for various indications in the management of renal tumors. While historically used for palliation of local symptoms (pain or hematuria), this technique has theoretical use in facilitating radical nephrectomy by allowing early ligation of the renal vein, decreasing blood loss and creating edema in resection planes. A common impediment to embolization is the development of postembolization syndrome (PES), which has been reported to have an incidence as high as 89%. This study reports the authors' experience with RAI as a safe palliative and adjunctive procedure over 4 years. MATERIAL AND METHODS: From 2008 to 2011, 113 patients underwent complete RAI at Washington Hospital Center for palliative or adjunctive therapy by an interventional radiologist. Procedures were performed in a radiology suite using mild sedation with vascular access obtained by femoral artery puncture. RAI was performed by subsegmental injection of polyvinyl alcohol particles. RESULTS: All 113 patients underwent successful RAI with confirmation of total arterial flow ablation via postprocedure arteriogram: 38 underwent embolization for preoperative adjunctive therapy, 34 for palliation of renal mass, 36 for trauma/hemorrhage and five for symptomatic renal artery pseudoaneurysm after partial nephrectomy. PES occurred in 33 out of 75 patients (44.0%), with symptomatic PES in only two patients (2.6%). No major complications (>Clavien grade III) occurred. Thirty-eight patients were excluded from analysis as they underwent radical nephrectomy within 24 h, preventing accurate assessment of PES. CONCLUSIONS: RAI is a safe and reliable procedure for palliation of renal masses, as an adjunctive procedure for radical nephrectomy, and for conservative management of renal hemorrhage or aneurysm. PES occurs in relatively few patients, with no major complications, and should not impede clinical consideration of this procedure.
