The article presents a study aimed at analyzing patient population to determine whether anatomic or plaque characteristics could predict increased risk of stroke in patients undergoing carotid artery stenting. It concludes that degree of internal carotid artery (ICA) stenosis and aortic arch calcification may be linked to an increased risk of a perioperative neurologic event after carotid artery stenting but that arch type and ICA/common carotid artery (CCA) angulation are not.

Allogeneic hematopoetic stem cell transplantation in pediatric myelodysplastic syndromes: Improved outcomes for de novo disease. Pediatr Transplantation 2011: 15: 334-343. © 2011 John Wiley & Sons A/S. We report 23 consecutive pediatric patients with MDS who received allogeneic HSCT on IRB approved protocols between 1992 and 2009 at Children's Memorial Hospital (Chicago, IL). Nine patients had de novo MDS, whereas 14 patients had treatment-related MDS. All patients had a documented cytogenetic abnormality, and monosomy 7/7q− was seen in 12 patients (52%). Fourteen of 23 patients received a myeloablative conditioning regimen; RIC regimens were used for the remaining nine. Five patients relapsed post-transplant, including four patients who received RIC transplant and four patients with treatment-related MDS. For the entire group, estimated five-yr RFS and OS were 47% and 50%, respectively. Treatment-related MDS was associated with decreased RFS in comparison with de novo MDS (33% vs. 70%, p = 0.05). Five-year OS rates reached 80% for those with de novo MDS. RIC regimens were associated with decreased three-yr RFS in comparison with myeloablative regimens (22% vs. 68%, p = 0.02). There was no correlation of survival with blast count at diagnosis, IPSS score, cytogenetic abnormality, donor type, or HLA match. Larger series are needed to confirm prognostic factors so that higher-risk patients can be targeted with novel approaches. [ABSTRACT FROM AUTHOR]

Objective: We reviewed data on treatment of stage IB1 cervical cancer at our institution to compare recurrence, complications, and survival of women treated primarily by radical hysterectomy versus radiation., Methods: Records for women treated for stage IB1 cervical cancer between January 1, 1990 and June 1, 2010 were retrospectively reviewed. Recurrence, survival outcomes, and complications were examined and compared. Demographic, clinical, and histopathologic factors were also analyzed., Results: Of 198 patients with stage IB1 cervix cancer, 169 (85%) underwent radical hysterectomy, including 37 (20%) who received postoperative radiation, and 29 (15%) were treated primarily with radiotherapy±chemotherapy. Progression-free survival, overall survival, and disease-specific survival were all longer in the surgery group (89%, 95%, and 96%) versus the radiation group (70%, 70%, and 78%), respectively (P<0.001). Patients in the radiation group were older, had larger tumors, and were more likely to have medical comorbidities than patients in the surgery group. Within the surgical cohort, lymphvascular space invasion, outer third cervical stromal invasion, positive surgical margins, and lymph node metastasis were all predictive of recurrence (P<0.002), whereas histopathology, smoking, diabetes, and immunosuppression were not. Grade 3 or 4 complication rates were higher among the 29 patients who had primary radiotherapy (20.7%) and the 37 patients who had surgery followed by radiotherapy (21.6%) compared with the 132 patients who had surgery only (9.1%) (P=0.047)., Conclusions: Primary treatment of stage IB1 cervix cancer with radical hysterectomy±adjuvant radiation resulted in a significantly lower rate of recurrence and an improved survival with fewer complications compared with radiotherapy with or without chemotherapy.

BRCA1/BRCA2 mutations are common and the hallmarks of high-grade serous ovarian carcinoma. We found that MIR182, a negative BRCA1 regulator, is significantly overexpressed in high-grade serous ovarian carcinoma. To examine whether overexpression of MIR182 and its target genes, including BRCA1, HMGA2 (high-mobility group A2), FOXO3 and MTSS1, are associated with high-grade serous ovarian carcinoma tumor types and clinical outcome, we studied MIR182 by in situ hybridization and its target gene expression by immunohistochemistry in 117 cases of advanced ovarian cancer. We found that high-grade serous ovarian carcinoma had significantly higher MIR182 (P=0.0003) and HMGA2 (P=0.04) expression, and significantly lower BRCA1 (P<0.0001) and FOXO3 (P<0.001) expression than normal controls. MIR182 is significantly correlated with MTSS1 expression (r=0.31; P<0.001), whereas other target genes did not show a significant correlation with MIR182, indicating a complicated regulatory mechanisms of these genes in high-grade serous ovarian carcinoma. Among the examined MIR182 target genes, only HMGA2 was significantly associated with serous type carcinomas (P<0.01), ascites (P<0.01) and high death rate (P=0.02). FOXO3 expression was associated with lower-stage disease (P=0.04) and solid growth pattern (P=0.03). MIR182 expression is significantly higher in high-grade serous ovarian carcinoma than in fallopian tubes.
