BackgroundThe role of postoperative adjuvant treatment for sinonasal malignant melanoma remains unclear. This study evaluates the impact of three different surgical and postoperative adjuvant treatment modalities: surgery alone(open and endoscopic approaches), surgery plus radiotherapy and surgery, radiotherapy plus chemotherapy on survival of patients with primary sinonasal malignant melanoma (SMM).MethodsThe data of 69 patients who underwent primary surgical treatments at Eye & ENT hospital of Fudan University between January 1st, 2000 and December 31st, 2010 were retrospectively reviewed. Survival comparison of different surgical and postoperative adjuvant treatment modalities (surgery alone, surgery plus radiotherapy and surgery, radiotherapy plus chemotherapy), as well as survival comparison between open and endoscopic surgical approaches were performed. Curves depicting survival were performed using Kaplan-Meier method. Statistical analysis was performed using log-rank test software SPSS19 and p < .05 is considered as statistically significant.ResultsThe median overall survival time was found to be 18 months for surgery alone (27 cases), 32 months for surgery plus radiotherapy (24 cases), 42 months for surgery, radiotherapy plus chemotherapy (18 cases). The 3 and 5 year survival rates for groups mentioned above were 14.8% and 5.6%, 45.1% and 31.6%, 55% and 32.1%, respectively. Statistical significances were found not only between surgery alone and surgery plus radiotherapy treatment group (P = 0.012), but also surgery alone and surgery, radiotherapy plus chemotherapy group (P = 0.002). There was no statistically significant survival difference found between the two different surgical approaches (41 cases for open approach and 28 cases for endoscopic approach).ConclusionsSinonasal malignant melanoma is a disease with a poor prognosis. Patients who underwent surgery plus radiotherapy or surgery, radiotherapy plus chemotherapy had better survival outcomes than those underwent surgery alone. Endoscopic approach provided similar survival outcome as an open approach.

RESULTS showed that JNA expressed ER-α (92.9%), ER-β (91.4%), AR (65.7%), PR (12.8%), and VEGF (95.7%) at different levels. High level of VEGF was linked to elevated ER-α and ER-β. There was no significant relationship between hormonal receptors and age at diagnosis, tumor stage or bleeding. However, overexpression of ER-α was found to be an indicator of poor prognosis (p = 0.031).

MVD is a useful predictor for poor prognosis of patients with JNA after curative resection. Angiogenesis, which may play an important role in the occurrence and development of JNA, is therefore a potential therapeutic target for JNA.

Transnasal endoscopic approach can be successfully used for Radkowski's stages I-IIb tumors and selective IIc-IIIb lesions, allowing for less blood loss, fewer postoperative complications, and a lower percentage of recurrence in comparison to open surgery. The management of recurrent tumor is complex, should be individually tailored, and should take into account tumor location, patient age, complications of treatment, and the possibility of spontaneous involution, to better define treatment strategy.

Background Allergen‐specific immunotherapy (AIT) is the only available treatment that can induce specific immune tolerance to allergens. However, the treatment course lasts >3 years, and there is no reliable method to predict treatment response. Therefore, in this study we aimed to establish a method that can predict treatment response to AIT in the second year. Methods This prospective study enrolled 119 patients who had undergone 2‐years of standard‐quality house dust mite subcutaneous immunotherapy. Clinical characteristics, skin‐prick test response, and treatment response were evaluated at months 4, 6, 12, and 18. Effective AIT was defined as a 25% reduction in average adjusted symptom score (AAdSS) from baseline at the end of the second year of immunotherapy. Results The overall efficacy rate at the end of year 2 of the AIT was 67.4%. Age, sex, asthma, body mass index, smoking history, and aeroallergen categories were not associated with efficacy of AIT. Meanwhile, efficacy data at month 4 (odds ratio [OR], 4.250; p = 0.004), month 6 (OR, 10.476; p < 0.000), month 12 (OR, 18.000; p < 0.000), and month 18 (OR, 9.716; p < 0.000) were associated with month 24 efficacy. The area under the curve for improvement at 4, 6, 12, and 18 months was 0.805, 0.834, 0.837, and 0.854, respectively. Conclusion Efficacy of AIT at months 4, 6, 12, and 18 is strongly associated with efficacy at month 24. Efficacy as early as month 4 can predict efficacy at the second year, and this may help to determine the need for long‐term treatment. Our findings may be useful for identifying novel treatment strategies for AIT.
