Patient
age, sex, tumor size, RENAL nephrometry score, complications, and recurrences were recorded.
Results: One hundred-sixteen patients (66.4% male, 33.6% female) with 116 tumors underwent renal mass CA with a mean follow-up of 27.4 months (range 1-112 mos). Mean tumor size was 2.76 +/- 0.97 cm (range 1.1-5.5 cm). Twenty-seven complications occurred in 23 patients for an overall complication rate of 19.8%. Low-grade complications (Clavien I and II) accounted for 92.6% (n = 25) of overall complications. https://www.selleckchem.com/products/GSK461364.html Seven (6%) patients had enhancement on initial imaging and were considered incomplete ablations. Local recurrence and metastatic disease developed in four and one patients, respectively. In patients with biopsy-proven renal-cell carcinoma (RCC), the 2- and 5-year recurrence-free survival (RFS) probability was 0.83 (95% confidence interval [CI]: 0.74, 0.95) and 0.77 (95% CI:
0.60, 0.94), respectively. After excluding biopsy proven RCC patients with incomplete ablations, the 2-and 5-year RFS increased to 0.91 (95% Z-VAD-FMK Apoptosis inhibitor CI: 0.82, 1.00) and 0.85 (95% CI: 0.71, 1.00) respectively.
Conclusion: CA of renal masses results in acceptable oncologic efficacy accompanied by a tolerable complication profile in a cohort with a mean follow-up of 27.4 months. CA remains a viable treatment option for small renal masses in selected patients.”
“Background: In Parkinson’s disease (PD), the response to L-dopa is highly variable and unpredictable. The major pathway for dopamine synthesis from L-dopa is decarboxylation by aromatic L-amino acid decarboxylase (AAAD, encoded by the DDC gene).
Objective: To determine the motor response to L-dopa in PD patients
as a function of the DDC gene promoter Cyclosporin A polymorphisms (rs921451 T > C polymorphism (DDCT/G) and rs3837091 AGAG del (DDCAGAG/-)).
Methods: Thirty-three Caucasian PD patients underwent an acute L-dopa challenge together with the peripheral AAAD inhibitor benserazide and were genotyped for rs921451 and rs3837091. The primary efficacy criterion was the motor response to L-dopa, as estimated by the area under the curve for the change in the Unified Parkinson’s Disease Rating Scale part III (UPDRS) score relative to baseline (AUC(Delta UPDRS)) in the 4 h following L-dopa administration. Secondary endpoints were pharmacokinetic parameters for plasma levels of L-dopa and dopamine. Investigators and patients were blinded to genotypes data throughout the study.
Results: When adjusted for the L-dopa dose, the AUC(Delta UPDRS) was significantly lower in DDCCC/CT patients (n = 14) than in DDCIT patients (n = 19) and significantly lower in DDC-/- (or) (AGAG/-) patients (n = 8) than in DDCAGAG/AGAG patients (n = 25). There were no significant intergroup differences in plasma pharmacokinetic parameters for L-dopa and dopamine.
