Cross-Cultural Adaptation and Validation of the Italian Version of SWAL-QOL

The aim of the study was to evaluate the reliability and validity of the Italian SWAL-QOL (I-SWAL-QOL). The study consisted of five phases: item generation, reliability analysis, normative data generation, validity analysis, and responsiveness analysis. The item generation phase followed the five-step, cross-cultural, adaptation process of translation and back-translation. A group of 92 dysphagic patients was enrolled for the internal consistency analysis. Seventy-eight patients completed the I-SWAL-QOL twice, 2 weeks apart, for test–retest reliability analysis. A group of 200 asymptomatic subjects completed the I-SWAL-QOL for normative data generation. I-SWAL-QOL scores obtained by both the group of dysphagic subjects and asymptomatic ones were compared for validity analysis. I-SWAL-QOL scores were correlated with SF-36 scores in 67 patients with dysphagia for concurrent validity analysis. Finally, I-SWAL-QOL scores obtained in a group of 30 dysphagic patients before and after successful rehabilitation treatment were compared for responsiveness analysis. All the enrolled patients managed to complete the I-SWAL-QOL without needing any assistance, within 20 min. Internal consistency was acceptable for all I-SWAL-QOL subscales (α > 0.70). Test–retest reliability was also satisfactory for all subscales (ICC > 0.7). A significant difference between the dysphagic group and the control group was found in all I-SWAL-QOL subscales (p < 0.05). Mild to moderate correlations between I-SWAL-QOL and SF-36 subscales were observed. I-SWAL-QOL scores obtained in the pre-treatment condition were significantly lower than those obtained after swallowing rehabilitation. I-SWAL-QOL is reliable, valid, responsive to changes in QOL, and recommended for clinical practice and outcome research.     

Recurrent glioblastoma: which treatment? A real-world study from the Neuro-oncology Unit “Regina Elena” National Cancer Institute

Neurological Sciences - The majority of patients with glioblastoma (GBM) experience disease progression. At recurrence, treatment options have limited efficacy. Many studies report a limited and...     

Outcome of a phase II prospective study on partial breast irradiation with interstitial multi-catheter high-dose-rate brachytherapy

Background and purpose

Partial breast irradiation (PBI) is an alternative to whole-breast irradiation after breast-conserving surgery in selected patients. Until the results of randomized phase III studies are available, phase II studies inform about PBI. We report the 5 year results of a phase II prospective study with PBI using interstitial multi-catheter high-dose-rate brachytherapy (ClinicalTrials.gov Identifier: NCT00499057).

Methods

Hundred patients received PBI (4 Gy, twice a day for 4 days, until 32 Gy). Inclusion criteria were: age ?40 years, infiltrating carcinoma without lobular histology, ductal in situ carcinoma, tumor size ?2.5 cm, negative surgical margins and axillary lymph nodes.

Results

At a median follow-up of 60 months late toxicity occurred in 25 patients; the 5-year probability of freedom from late toxicity was 72.6% (95% CI: 63.7–81.7). Tamoxifen was the only significant risk factor for late toxicity. Cosmetic results, judged by physicians and patients, were good/excellent in 98 patients. Three local relapses (1 true, 2 elsewhere) and 1 regional relapse occurred. The 5-year probability of local or regional relapse-free survival was 97.7% (95% CI: 91.1–99.4) and 99.0% (95% CI: 92.9–99.8), respectively.

Conclusion

PBI with interstitial multi-catheter brachytherapy is associated with low relapse and late toxicity rates.     

Endoscopic and combined external–transnasal endoscopic approach for the treatment of inverted papilloma: analysis of 110 cases

The aim of the study was to evaluate the effectiveness of the endoscopic approach for the management of inverted papilloma (IP) of the nose and paranasal sinuses and the possible factors associated with its recurrence. One hundred and forty-one patients affected by an IP originating at the level of the sinonasal tract were treated surgically using an endoscopic technique alone or a combined external–endoscopic approach at the ENT Department of the University of Bologna between January 1994 and December 2012. Of these patients, 110 were selected for the recurrence analysis. Univariate and multivariate analyses were performed to detect risk factors for IP recurrence. The patients had a mean follow-up of 56.7 months (24–167 months). Seven cases (6.3 %) of recurrence were observed in patients treated with the endoscopic approach for the primary or recurrent tumor. Previous surgery (p = 0.005) and number of previous surgical procedures (p = 0.003) were associated with higher recurrence rate. The number of previous operations was associated to recurrence-free survival at Cox regression analysis. In our study, the endoscopic approach showed itself to be a useful tool for the radical resection of an IP. The endoscopic approach should be tailored for the different extensions of IP. Recurrent cases showed an increased risk of further recurrence. Therefore, these should be treated paying particular attention to the boundaries of the primary tumor.     

Endoscopic treatment of benign tumors of the nose and paranasal sinuses.

OBJECTIVE: The endoscopic approach can be successfully employed for the treatment of benign tumors such as fibroosseus and vascular lesions, pleomorphic adenomas, gliomas, and schwannomas. STUDY DESIGN AND SETTING: Nineteen patients diagnosed with benign tumors of the nasal cavity and paranasal sinuses and treated using an endoscopic approach were retrospectively reviewed. The endoscopic approach was used exclusively in 15 cases and was associated with an external approach in 4 cases (due to an intracranial extension of the tumor in 3 patients and its location at the level of the anterior wall of the frontal sinus in the last case). RESULTS: The resection of the lesions was radical in 18 patients and subtotal in 1 case. The mean follow-up was 27 months and only 1 recurrence (5%) was observed in the juvenile angiofibroma group 20 months postoperatively. CONCLUSION: and significance In selected cases, endoscopic surgery can be considered an effective treatment for the resection of benign tumors involving the sinonasal tract.
