Information regarding patient outcomes, complications, and mortality after surgery for spinal metastasis has previously been derived from single-institution series. The aim of this study was to report inpatient mortality, complications, and outcomes on a national level. ⋯ A national perspective is provided on inpatient complications and outcomes after surgery for spinal metastasis in the U.S. The significant negative effect of postoperative complications on mortality and resource utilization is demonstrated. Furthermore, preoperative comorbidity is identified as an important risk factor and its impact is defined on patient outcomes.

Little is known regarding chemotherapy medication errors in pediatrics despite studies suggesting high rates of overall pediatric medication errors. In this study, the authors examined patterns in pediatric chemotherapy errors. ⋯ Pediatric chemotherapy errors often reached the patient, potentially were harmful, and differed in quality between outpatient and inpatient areas. This study indicated which chemotherapeutic agents most often were involved in errors and that administering errors were common. Investigation is needed regarding targeted medication administration safeguards for these high-risk medications.

The objective of this study was to investigate prognostic factors and clinical outcome of myxoid/round cell and pleomorphic liposarcoma. ⋯ Myxoid/round cell liposarcomas shared similar prognostic factors with other soft tissue sarcomas and had a relatively good clinical outcome. The presence of >5% of round cell component singled out a group of patients at greater risk of metastases and death but with a broad spectrum of disease aggressiveness. Extrapulmonary metastases were a peculiar pattern of myxoid/round cell liposarcoma that require special consideration for treatment and prognosis.

The 2002 American Joint Committee on Cancer (AJCC) tumor classification for renal cell carcinoma (RCC) does not take into account concomitant venous invasion and extrarenal tumor extension (ERE). In the current study, the authors evaluated the prognostic significance of venous tumor thrombus (VTT) and its extent, the presence and location of ERE, and a combination of both features on survival after the surgical management of patients with pathologic T3 (pT3) RCC. ⋯ The prognostic accuracy of the 2002 AJCC pT3 tumor classification can be improved by subclassifying patients with ERE only and those with VTT only into a prognostic category that is separate from patients with both ERE and VTT.

Brachytherapy, active surveillance, and watchful waiting are increasingly being offered to men with low-risk prostate cancer. However, many of these men harbor undetected high-grade disease (Gleason pattern > or =4). The ability to identify those individuals with occult high-grade disease may help guide treatment decisions in this patient cohort. ⋯ The authors identified significant predictors of upgrading for patients diagnosed with low-risk prostate cancer. A nomogram based on these study findings could help physicians further risk-stratify patients with low-risk prostate cancer before embarking on treatment. Caution should be exercised in recommending nonradical therapy to individuals with a high probability of undetected high-grade disease.
