Pediatric Sedation Unit: A Safe, Effective, and Satisfactory Alternative to Outpatient Pediatric Urological Procedures Under Anesthesia.

Introduction: The operating room is an increasingly expensive and limited resource. The aim of this study was to evaluate the efficacy, safety, cost, and parental satisfaction of transitioning minor pediatric urology procedures from an operating room setting to a pediatric sedation unit.

Methods: Minor urological procedures were transitioned from the operating room to the pediatric sedation unit if they could be completed in 20 minutes using minimal instrumentation.

Accuracy of clinical nodal staging and factors associated with receipt of lymph node dissection at the time of surgery for nonmetastatic renal cell carcinoma.

Introduction: The benefit of lymph node dissection (LND) in renal cell carcinoma (RCC) remains poorly defined. Despite this uncertainty, the American Urological Association (AUA) guideline on localized renal cancer recommends that LND be performed for staging purposes when there is suspicion of regional lymphadenopathy on imaging. Using the National Cancer Database (NCDB), we sought to determine how much of a departure the new AUA guideline is from current practice.

Survival outcomes of diffuse large B-cell lymphoma by association with concurrent or antecedent follicular lymphoma and double hit status.

Diffuse large B-cell lymphoma (DLBCL) transformed from follicular lymphoma (FL) (tDLBCL) has been traditionally associated with an aggressive course, but more recent studies have shown longer survivals. The clinical significance of concurrent FL at the time of diagnosis of DLBCL (cDLBCL/FL) is less clear. We compared outcomes of tDLBCL, cDLBCL/FL, and DLBCL (dDLBCL) and then evaluated the impact of double hit (DH) rearrangements (MYC with BCL2 and/or BCL6) in these subgroups' outcomes.

Outcomes of Patients With Double-Hit Lymphoma Who Achieve First Complete Remission.

Purpose Patients with double-hit lymphoma (DHL) rarely achieve long-term survival following disease relapse. Some patients with DHL undergo consolidative autologous stem-cell transplantation (autoSCT) to reduce the risk of relapse, although the benefit of this treatment strategy is unclear. Methods Patients with DHL who achieved first complete remission following completion of front-line therapy with either rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) or intensive front-line therapy, and deemed fit for autoSCT, were included.

Sole rearrangement but not amplification of MYC is associated with a poor prognosis in patients with diffuse large B cell lymphoma and B cell lymphoma unclassifiable.

Rearrangement of MYC is associated with a poor prognosis in patients with diffuse large B cell lymphoma (DLBCL) and B cell lymphoma unclassifiable (BCLU), particularly in the setting of double hit lymphoma (DHL). However, little is known about outcomes of patients who demonstrate MYC rearrangement without evidence of BCL2 or BCL6 rearrangement (single hit) or amplification (>4 copies) of MYC. We identified 87 patients with single hit lymphoma (SHL), 22 patients with MYC-amplified lymphoma (MYC amp) as well as 127 DLBCL patients without MYC rearrangement or amplification (MYC normal) and 45 patients with DHL, all treated with either R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) or intensive induction therapy.
