ABSTRACT
Objective: To investigate the short-term efficacy of anti-IgE monoclonal antibody (Omalizumab) in the treatment of recurrent chronic rhinosinusitis with nasal polyps (CRSwNP) complicated with asthma. Methods: Patients with recurrent CRSwNP and comorbid asthma in Beijing TongRen Hospital from May to December of 2020 were continuously recruited and received a 4-month therapy of stable background treatment plus Omalizumab. Results of visual analog scales (VAS) of nasal symptoms, sino-nasal outcome test-22 (SNOT 22) and nasal polyp scores were collected at baseline and post-treatment (1, 2, 3 and 4 months after treatment). Blood routine tests, total nasal resistances (TNR), minimum cross-sectional areas (MCA), total nasal cavity volumes (NCV), forced expiratory volumes in one second (FEV1)/forced vital capacity (FVC) and adverse events were collected at baseline and 4 months after treatment. All results were evaluated for short-term efficacy of Omalizumab. GraphPad Prism 8.2.1 was used for statistic analysis. Results: Ten patients were collected, including 3 males and 7 females, aged (41.13±12.64) years old (x¯±s). Compared to results at baseline, the VAS scores of nasal obstruction, rhinorrhea, hyposmia and headache after 4 months treatment were significantly decreased (1.80±1.48 vs 6.70±2.83, 2.40±1.27 vs 6.40±3.44, 2.70±2.91 vs 8.20±2.25, 0.60±1.08 vs 3.60±2.72, t value was 5.045, 4.243, 5.312, 3.402, respectively, all P<0.01). The scores of SNOT-22 (25.6±20 vs 61.3±33.32, t=4.127, P=0.002 6), nasal polyp scores (2.20±0.92 vs 4.60±0.84, t=9.000, P<0.01) and the count and percentage of eosinophils in peripheral blood were significantly decreased ((94.10±97.78)×109/L vs (360.00±210.80)×109/L, (32.90±27.06)% vs (64.40±20.73)%, t value was 3.678, 2.957, respectively, all P<0.05). NCV (0-5 cm and 0-7 cm) of patients were improved from baseline ((12.62±2.84) cm3 vs (10.40±2.09) cm3, (27.50±14.15) cm3 vs (16.81±6.40) cm3, t value was 2.371, 2.445, respectively, all P<0.05). Conclusions: The 4-month treatment of Omalizumab can significantly improve the nasal symptoms and quality of life of patients with recurrent CRSwNP complicated with asthma, shrink nasal polyps size and reduce the number of peripheral blood eosinophils. Omalizumab can be used as an alternative therapy for refractory CRSwNP patients in the future.

<p><b>OBJECTIVE</b>To analyze the prevalence and distribution of cervical node metastases in squamous cell carcinoma of hypopharynx and evaluate the efficacy of selective neck dissection (SND) on the treatment of the neck metastases.</p><p><b>METHODS</b>A retrospective review was performed for 63 patients with squamous cell carcinoma of hypopharynx from January 1990 to December 2004. Lymph nodes were clinically negative in 17 patients and positive in 46 patients. There were 15 unilateral SND, 22 bilateral SND and 16 modified radical neck dissections (MRND). Ipsilateral MRND or radical neck dissections (RND) and contralateral SNDs were performed in 10 cases. Forty-eight patients were followed up and the follow-up interval ranged from 24 to 143 months and the median was 41 months.</p><p><b>RESULTS</b>Lymph nodes were pathologically negative (pN0) in 22 and positive (pN +) in 41 patients. A total of 106 positive nodes were found in 95 neck dissections. The distribution of the positive nodes were as follows: Level II 47.2% (50/106), Level III33.0% (35/106), Level IV11.3% (12/106), Level V2.8% (3/106), Level VI 5.7% (6/106). Contralateral nodal metastases and recurrence were observed in both cN0 and cN + cases. There were 18 neck recurrent cases. High incidence of neck recurrence after SND was found in level II and III. The 3-year estimated survival rate analysis were 58.1% for the pN0 and 44.9% for pN1 and 41.1% for pN2 patients. Cox regression analysis suggested N stage was the most important prognostic factor. The risk ratio was 1.7 in pN1 and 2.2 in pN2.</p><p><b>CONCLUSIONS</b>Lymphatic metastases was the most significant prognostic factor of hypopharyngeal squamous cell carcinoma. Bilateral selective neck dissection, when carefully indicated, offers functional advantages without oncologic compromise.</p>
