The study aimed to verify the prognostic utility, therapeutic application and clinical benefits of tumor substaging and HER2 status in papillary non-muscle invasive bladder cancer (NMIBC). Select NMIBC transurethral resection specimens from 141 patients were used to construct tissue microarrays for assessing the substaging, HER2 protein expression by immunohistochemistry (HER2-IHC) and gene amplification by dual-color silver in situ hybridization (HER2-SISH). Substages were identified by the differing depth of tumor invasion (pTa / pT1a / pT1b / pT1c). HER2 protein expression was semiquantitatively analyzed and grouped into negative (score 0, 1+) and positive (score 2+, 3+). Other clinicopathological variables were also investigated. For NMIBC, HER2-IHC and HER2-SISH showed positive results in 6/141 (4.3%) and 4/141 (2.8%) respectively, which correlated well with tumor substaging. In multivariate analysis, substaging, HER2-IHC, and HER2-SISH were found to be independent predictors of progression-free survival (P < 0.001, P < 0.001, P = 0.031). HER2-IHC was the sole independent predictor of recurrent free survival in NMIBC (P = 0.017). It is suggested that tumor substaging and HER2 status are independent predictive markers for tumor progression or recurrence, and thus could be included in diagnostic and therapeutic management for NMIBC.

Foreign bodies in the colon are encountered with increasing frequency, but only sporadic reports concerning their management have appeared in the literature. While most ingested foreign bodies usually pass through the gastrointestinal tract uneventfully, sharp foreign bodies such as toothpicks infrequently cause intestinal perforation and may even result in death. We report our experience with a patient with a sigmoid colon pseudodiverticulum formation, a complication of accidental ingestion of a toothpick that was diagnosed and successfully managed colonoscopically. 相似文献

Adult patients with t(8;21) acute myeloid leukemia had no superior treatment outcome to those without t(8;21): a single institution’s experience 总被引:3,自引:0,他引:3

Clinical features and treatment outcome of 31 patients over 16 years of age with t(8;21) acute myeloid leukemia (AML) were compared with 60 patients without t(8;21). Among 31 patients with t(8;21), 15 patients were classified as AML-M2 and 11 and 5 patients as AML-M4 and M1, respectively. Of these patients, 28 patients (90.3%) achieved complete remission and 22 patients received consolidative treatment: intermediate-dose cytarabine (IDAC) 11, high-dose cytarabine (HDAC) 6, and allogeneic bone marrow transplantation (BMT) 5. When compared with patients without t(8;21), we could not demonstrate better treatment outcome for t(8;21) AML [median event-free survival (EFS) and overall survival (OS) 10.3 and 12.5 months in AML with t(8;21) vs 11.5 and 15.6 months in AML without t(8;21)]. In the t(8;21) AML group, patients who received HDAC consolidation did not show superior treatment outcome to those who received other consolidative treatment [median EFS: IDAC 11.9 months vs HDAC 9.2 months vs allogeneic BMT 38.1 months (P=NS) and median OS: IDAC 17.8 months vs HDAC 12.0 months vs allogeneic BMT 47.3 months (P=NS)]. Similar treatment outcome between patients with and without t(8;21) and non-superior treatment outcome of HDAC consolidative chemotherapy in the t(8;21) AML group in our study is contradictory to previous reports.These two authors equally contributed to this study: K.-W.
