    The recent increase in the incidence of oropharyngeal cancer in the USA and northern Europe has been attributed to human papillomavirus (HPV) infection. Because the carcinogenic mechanism of HPV related oropharyngeal cancer (OPC) is different from that of other OPC, biological malignancy and treatment effects are considered to be different between the two groups. We performed a prospective study in the Japanese cooperative study group for basic research in head and neck cancer (JCSG-BRHNC) to compare the effects of first-line treatment between HPV positive or negative stage Ⅲ and Ⅳ OPC.<br>From May 2014 to March 2016, 92 patients were enrolled by 18 institutions in the whole country. Sixty-five patients (71%) were HPV-positive in the PCR. We examined the effects of primary treatment in a prognosis investigation conducted one year after registration. The results showed that 60 of the 65 HPV-positive cases successfully achieved complete response (CR), and the primary treatment success ratio was 92.3% as the ratio of CR cases without recurrence or metastasis within one year. In comparison, 15 cases (57.7%) of 26 HPV-negative patients successfully achieved CR. The effect of chemoradiotherapy was high, and even cetuximab combination radiotherapy (BRT) showed enough effects for HPV-positive cases. Also, induction chemotherapy (IC) was successful and all cases achieved CR in RT singularity cases. These results will provide a useful reference when examining clinical trials that lower the intensity of treatment for HPV-positive cases.

    The number of patients attacked by bears has been rising recently because the opportunity to encounter wild bears has increased. Since injury by a bear attack mostly occurs in the head and neck region and can be fatal, adequate and immediate treatment is required.<br>We report 13 cases of injury inflicted by bears treated in our department and discuss the issues that are important in the treatment of these injuries. All 13 patients thought to have been attacked by black bears (<i>Ursus thibetanus japonicus</i>) suffered from facial contusions. Ten cases had facial bone fractures and four cases went blind in one eye. After the head and neck region, the arms had many injuries and three cases suffered bone fractures in their limbs and the trunk. Three patients developed hemorrhagic shock, however, there were no deaths. Four cases needed local flap reconstruction or skin grafting for defects of facial soft tissue.<br>It is important to know the features of injuries and to consult a specialist based on the sites and severity of the injuries for the treatment of bear-inflicted injuries.

  • The problems of Endoscopic-laryngeal pharyngeal surgery after Chemoradiotherapy

    Kawasaki Yohei, Tsuji Tadahiro, Suzuki Shinsuke, Yamada Takechiyo

    JOURNAL OF JAPAN SOCIETY FOR HEAD AND NECK SURGERY ( JAPAN SOCIETY FOR HEAD AND NECK SURGERY )  27 ( 3 ) 269 - 275   2018

    Endoscopic-laryngeal pharyngeal surgery (ELPS) is a very effective treatment for early cancers, especially because operation time can be reduced, as well as because unnecessary chemoradiotherapy can be avoided. On the other hand, it was not until ELPS became widespread that early cancer could be eradicated with chemoradiotherapy. With progressive improvements in accurate endoscopic imaging, it has been become possible to detect early recurrence in patients who had previously been treated with chemoradiotherapy. However, when such patients are operated by ELPS, we sometimes encounter difficulties, including difficult device manipulation, unexpected advance of tumors, and obscure tumor margins. We present an analysis of our ELPS cases and identify the problems of ELPS performed after radical chemoradiotherapy.

  • A Case of Epipharyngeal Lipoma Causing Obstructing the Airway

    Lipoma, a benign tumor consisting of mature fat cells, occurs frequently in subcutaneous tissue but rarely in the pharyngeal submucosa. We report a case of epipharyngeal lipoma in a 54-year-old man seen for severe rhinolalia and snoring. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a well-defined solid mass occupying the pharyngeal space, whose histological biopsy disclosed to be lipoma. The tumor was surgically removed in an oral approach, relieving obstructive symptoms. The man remains symptom-free for one year and five months after the surgery.<br>
