UNLABELLED: The patient chiefly complained about headache and facial pain with recurrent epistaxis during the past two months. The pain started from the teeth and intermittent pinching headache especially on the left side. She also had mild epistaxis which healed itself. Later on the epistaxis became severe which couldn't be easily cured. Her nasopharyngoscopy examination showed a mass in nasopharynx while cranial CT scan indicated a huge mass in nasopharynx with erosion of skull base. Enhanced CT scan showed significant thickness in nasopharynx, upwards which became a huge mass breaking through skull base especially on the left side. Adjacent parapharyngeal space and paranasal sinuses and skull base were widely involved with the enlargement of neck lymph nodes. The chronic mastoiditis, ethmoiditis and maxillary sinusitis were also found. DIAGNOSIS nasopharyngeal nonkeratinizing squamous cell carcinoma (T4N2M0 stage IV).

Nasopharyngeal carcinoma (NPC) is the third most common malignancy with a high recurrence and metastasis rate in South China. Natural compounds extracted from traditional Chinese herbal medicines have been developed and utilized for the treatment of a variety of cancers with modest properties and slight side effects. Maackiain (MA) is a type of flavonoid that was first isolated from leguminous plants, and it has been reported to relieve various nervous system disorders and exert anti-allergic as well as anti-inflammatory effects. In this study, we demonstrated that MA inhibited proliferation, arrested cell cycle and induced apoptosis in nasopharyngeal carcinoma CNE1 and CNE2 cells in vitro and in vivo. The expression of the related proteins associated with these processes were consistent with the above effects. Moreover, transcriptome sequencing and subsequent Western blot experiments revealed that inhibition of the MAPK/Ras pathway may be responsible to the anti-tumor effect of MA on NPC cells. Therefore, the effects of MA and an activator of this pathway, tertiary butylhydroquinone (TBHQ), alone or combination, were investigated. The results showed TBHQ neutralized the inhibitory effects of MA. These data suggest that MA exerts its anti-tumor effect by inhibiting the MAPK/Ras signaling pathway and it has the potential to become a treatment for patients with NPC.

Objective: To summarize the application of temporalis muscle flap in the salvage nasopharyngectomy for advanced recurrent nasopharyngeal carcinoma (rNPC), and to provide guidance for the repair of extensive skull base defects in salvage rNPC. Methods: A total of 54 patients with the application of temporalis muscle flap in the salvage nasopharyngectomy for advanced rNPC were retrospectively analyzed, including 42 males and 12 females, aging from 29 to 71 years. There were 36 patients with rT3 and 18 patients with rT4. The surgical methods of temporalis muscle flap repair were summarized. The general situation, survival time and postoperative complications of patients were recorded, and the advantages and disadvantages of temporalis muscle flap were discussed. Results: The temporal muscle flap could completely cover the defect area of nasopharynx and skull base, without the need for other autologous repair materials. The follow-up period was 2 to 28 months. The survival rate of temporalis flap was 98.1% (53/54). The 1-year overall survival rate was 84.5% while 1-year progression-free survival rate was 49.0%. None of the patients had facial nerve injury. Three patients (5.6%) had necrosis of the cranial membrane required surgical intervention and four patients (7.4%) required a chonoplasty due to severe chonostril stenosis or chonostril atresia. Eleven cases (20.4%) had mouth opening restriction, chewing weakness, dysphagia and other eating difficulties. Conclusions: Temporalis muscle flap is an alternative flap for the salvage nasopharyngectomy for advanced rNPC. Temporal muscle flap shows high survival rate and wide coverage, but the surgeon should apprehend the possible complications and reduce the occurrence of them.
