RESUMEN

Small cell lung cancer (SCLC) has a propensity for brain metastases, which is associated with poor prognosis. We sought to determine predictors of overall survival (OS) and brain progression-free survival (bPFS) in SCLC patients with synchronous brain metastases at the time of initial SCLC diagnosis. A total of 107 SCLC patients with synchronous brain metastases treated at a single institution were included in this retrospective analysis. These patients had brain lesions present on initial staging imaging. Survival was estimated using the Kaplan-Meier method with log-rank test. Factors predictive of OS and bPFS were analyzed using Cox proportional hazards regression model. Median OS for the entire cohort was 9 months (interquartile range, 4.2-13.8 months) and median bPFS was 7.3 months (interquartile range, 3.5-11.1 months). OS was 30.3% at 1 year and 14.4% at 2 years, while bPFS was 22.0% at 1 year and 6.9% at 2 years. The median number of brain lesions at diagnosis was 3 (interquartile range, 2-8), and the median size of the largest metastasis was 2.0 cm (interquartile range, 1.0-3.3 cm). Increased number of brain lesions was significantly associated with decreased OS. Patients who received both chemotherapy and whole brain radiation therapy (WBRT) had improved OS (P=0.02) and bPFS (P=0.005) compared to those who had either chemotherapy or WBRT alone. There was no significant difference in OS or bPFS depending on the sequence of therapy or the dose of WBRT. Thirteen patients underwent upfront brain metastasis resection, which was associated with improved OS (P=0.02) but not bPFS (P=0.09) compared to those who did not have surgery. The combination of chemotherapy and WBRT was associated with improved OS and bPFS compared to either modality alone. Upfront brain metastasis resection was associated with improved OS but not bPFS compared to those who did not have surgery.

RESUMEN

OBJECTIVES: Cervical cytology screening has been successful in reducing deaths from cervical cancer. We sought to determine risk factors for abnormal Pap test results in women undergoing kidney transplant evaluation. MATERILAS AND METHODS: We retrospectively examined women undergoing kidney transplant evaluations from 2008 to 2011. Patients were stratified based on normal cytology and atypical/malignant cytology. RESULTS: Of 404 patients, 293 patients (72.5%) had normal cytologic findings, whereas 111 (27.5%) had abnormal findings. On univariate logistic regression analyses, patients who had chronic kidney disease with an autoimmune cause (odds ratio = 2.71 [95% confidence interval, 1.41-5.19]; P = .003), previous renal transplants (odds ratio = 2.64 [95% confidence interval, 1.20-5.82], P = .016), or age ≤ 50 years (odds ratio = 1.68 [95% confidence interval, 1.08-2.61], P = .022) were more likely to have abnormal findings. Patients with normal and abnormal findings had similar rates of dialysis use. On multivariate logistic regression, patients who had chronic kidney disease with autoimmune causes (odds ratio = 2.48 [95% confidence interval, 1.26-4.88]; P = .008) and who had previous renal transplants (odds ratio = 2.67 [95% confidence interval, 1.20-5.95]; P = .017) were more likely to have abnormal findings. CONCLUSIONS: Previous kidney transplant, autoimmune disease, and age ≤ 50 years were associated with abnormalities on cervical cancer screening in our female group of patients. Patients with these characteristics may benefit more from routine cervical cancer screening than other patients evaluated for kidney transplant.

RESUMEN

OBJECTIVES: Transplant centers often recommend, but not necessarily require, screening colonoscopies for people over 50 years of age in accordance with the US Preventative Services Task Force guidelines for the general population. We sought to identify risk factors affecting colonoscopy results in renal failure patients undergoing kidney transplant evaluation. MATERIALS AND METHODS: We retrospectively examined patients undergoing kidney transplant evaluation from 2009 to 2012 (n = 469 patients). Comparisons were made between colonoscopy reports categorized as normal (no finding or hyperplastic polyp) or abnormal (adenomatous polyp or carcinoma). RESULTS: Of 469 patients who met the study criteria, 303 (64.6%) had normal colonoscopies and 166 (35.4%) had abnormal colonoscopies. Logistic regression analysis showed that male sex (odds ratio = 2.09; 95% confidence interval, 1.37-3.20; P = .001) and increasing age (odds ratio = 1.04; 95% confidence interval, 1.01-1.08; P = .019) were more likely to correspond to abnormal findings. Those with dialysis vintage (length of time on dialysis) up to 3 years (odds ratio = 2.10; 95% confidence interval, 1.09-4.06; P = .027) and hypertension as the cause of renal failure (odds ratio = 1.79; 95% confidence interval, 1.05-2.87; P = .002) had more abnormal findings. No differences in length of evaluation, rate of being listed for transplant, and rate of transplant were shown. CONCLUSIONS: The overall rate of adenomatous findings on colonoscopy was higher among patients with pretransplant end-stage renal disease than in the general population, as shown in other studies. Age, sex, dialysis vintage up to 3 years, and hypertensive renal failure were associated with adenomatous polyps of the colon in this study population. Because adenomatous polyp rates are high in patients with chronic kidney disease who are undergoing transplant evaluation and colonoscopic findings do not appear to delay transplant evaluations or listing rates, screening colonoscopies should be encouraged.
