Objectives To identify independent predictors of outcome in patients with adenoid cystic carcinoma (ACC) of the paranasal sinuses and skull base.Design Meta-analysis of the literature and data from the International ACC Study Group.Setting University-affiliated medical center.Participants The study group consisted of 520 patients, 99 of them from the international cohort. The median follow-up period was 60 months (range, 32 to 100 months).Main Outcome Measures Overall survival (OS) and disease-specific survival (DSS).Results The 5-year OS and DSS of the entire cohort were 62% and 67%, respectively. The local recurrence rate was 36.6%, and the regional recurrence rate was 7%. Distant metastasis, most commonly present in the lung, was recorded in 106 patients (29.1%). In the international cohort, positive margins and ACC of the sphenoid or ethmoidal sinuses were significant predictors of outcome (p < 0.001). Perineural invasion and adjuvant treatment (radiotherapy or chemoradiation) were not associated with prognosis.Conclusion Tumor margin status and tumor site are associated with prognosis in ACC of the paranasal sinuses, whereas perineural invasion is not. Adjuvant treatment apparently has no impact on outcome.  相似文献

Objectives: To explore whether gaps exist between caretakers from different ethno-cultural groups (Israeli-born Jews [Sabras], Israeli Arabs [Arabs], and migrants from Russia [Russians]) regarding their perceptions of autonomy and human dignity of patients with dementia.

Design: A mixed-methods research scheme was used, comprised of qualitative and quantitative methods, utilizing semi-structured interviews and self-reported questionnaires. Twenty formal caretakers participated in the qualitative portion, and approximately 200 caretakers were included in the quantitative portion. All participants were recruited from three nursing homes and one hospital in the Galilee region (Israel).

Results: The qualitative portion of the study yielded eight themes encapsulated in the concept of autonomy and ten themes entailed within human dignity, in the context of care for patients with dementia. By utilizing these themes in the quantitative portion, substantial differences in nursing homes were found in the attitudes to autonomy and dignity of patients with dementia between Russian and Arab as well as Sabra caretakers (index score for autonomy: 2.97, 4.07, and 4, respectively; index score for dignity: 3.17, 4.1, and 4.07). A multi-variable regression, focusing on caretakers from nursing homes, showed the most significant influencing variables on the indexes of autonomy and dignity were ethno-culture Arab/Russian (0.84, 0.62) and the patient’s family (0.29, 0.30). Regarding the autonomy index, being a female caretaker also had a significant influence (0.24). In the hospital, no influence emerged for the ethno-culture variables, and neither type of institution showed any influence of religion or religiousness as well as societal or community norms.

Conclusions: Contrary to past research, in nursing homes, significant differences were found between certain ethno-cultural groups (Arabs and Russians) regarding their stance toward the dignity and autonomy of patients with dementia. Arab caretakers’ fostering of more encompassing conceptions of dignity and autonomy, irrespective of institutional setting, provides better grounds for person-centered care.  相似文献
