RESUMO
We present a case of cervical lymph node metastasis from an unknown primary cancer that was controlled with immunotherapy, chemotherapy, and surgery. The patient, a 61-year-old man, was referred to our department for treatment of a lesion in the left cervical lateral area. At the initial visit, the mass was covered by reddened skin and was elastic, hard, and immobile on palpation. The presence of a malignant disease such as malignant lymphoma or lymphadenitis because of infection by tubercle bacillus or Epstein-Barr virus was suspected on the basis of the clinical and magnetic resonance imaging findings. Biopsy and resection of the cervical mass was performed under general anesthesia. Because the pathological diagnosis during surgery indicated squamous cell carcinoma, the surgical approach was changed to neck dissection. Head, neck, and thoracic computed tomography and other examinations were performed to locate the primary cancer, but its origin remained unknown. Postoperative therapy consisted of chemotherapy and immunotherapy. The patient has been followed up for 4 years and 10 months without any evidence of recurrence.

OBJECTIVES/HYPOTHESIS: Vocal fold polyps and nodules are common benign laryngeal lesions. Currently, the Japanese health insurance system covers surgical interventions. However, the establishment of more cost-effective conservative methods is required, because healthcare costs are viewed as a major concern, and the government and taxpayers are demanding more economical, effective treatments. In this situation, more suitable vocal hygiene education may be important for the success of cost-effective conservative treatment. In this study, we developed a novel reinforced vocal hygiene education program and compared the results of this program with those of previous methods of teaching vocal hygiene. STUDY DESIGN: Multicenter randomized controlled trial. METHODS: Patients who visited a National Hospital Organization (NHO) hospital for the surgical indication of hoarseness were included in the study. Before undergoing surgery, 200 patients with benign vocal fold lesions (vocal fold polyps/nodules) were enrolled and randomly allocated to the NHO-style vocal hygiene educational program (intervention group) or control education program (control group). Two months after enrollment, the patients in both groups underwent laryngeal fiberscopic examinations to determine whether the benign lesions had resolved or whether surgery was indicated for the vocal fold polyps/nodules. RESULTS: After 2 months, in the intervention group, the proportion of lesion resolution (61.3%) was significantly greater than that in the control group (26.3%) (P < .001, Fisher exact test). CONCLUSIONS: Our results clearly indicate that the quality and features of the education program could affect the outcome of the intervention. We found that a reinforced vocal hygiene education program increased the rate of the resolution of benign vocal fold polyps and nodules in a multicenter randomized clinical trial. LEVEL OF EVIDENCE: 1b Laryngoscope, 2593-2599, 2018.

BACKGROUND: Cyclin D1 has been reported to be associated with poor prognosis in head and neck squamous cell carcinoma (HNSCC). PATIENTS AND METHODS: FISH was performed on 58 patients. Thirty-two received neoadjuvant chemotherapy (NAC) as primary treatment and 21 with hypopharyngeal squamous cell carcinoma (HPC) received chemoradiotherapy. RESULTS: CCND1 amplification was identified in 31 (53%) patients and the incidence was higher in HPC (p = 0.0068). Four (31%) out of 13 patients with CCND1 amplification responded to NAC whereas the response rate in the non-amplified group was 79% (p = 0.011). CCND1 amplification with a homogeneously staining region (HSR) was accompanied by cyclin D1 protein overexpression (p < 0.0001). HPC showed HSR more frequently (p = 0.033) and the survival rate of the subgroup with HSR was lower than that without (p < 0.05). CONCLUSION: Detection of CCND1 amplification using FISH may be a useful marker of sensitivity to NAC and chemoradiotherapy for HNSCC.

BACKGROUND: ONO-4817 is a novel matrix metalloproteinase (MMP) inhibitor which has a broad inhibitory spectrum for MMPs. We investigated the inhibitory effect of ONO-4817 on cervical lymph node metastasis of tongue carcinoma. MATERIALS AND METHODS: HSC-3-M3, a cell line derived from human tongue carcinoma with high metastatic potential for lymph node, was used. The direct cytotoxicity of ONO-4817 was assessed by MTT assay and the gelatinolytic activity by gelatin zymography and film in situ zymography (FIZ). The inhibitory effect on lymph node metastasis was examined by orthotopic implantation model with nude mice. RESULTS: ONO-4817 had no direct cyototoxicity on HSC-3-M3 cells. Gelatin zymography and FIZ demonstrated a suppression of MMP-9 activation and a marked inhibition of gelatinolysis. Additionally, a suppression of cervical lymph node metastasis was shown by therapeutic experiment. CONCLUSION: The MMP inhibitor, ONO-4817, is a candidate for adjunctive therapy of cervical lymph node metastasis in tongue carcinoma.

Cases of squamous cell carcinoma of the maxillary sinus initially treated at Keio University Hospital between January 1981 and December 1998 studied retrospectively involved 60 untreated cases--46 men and 14 women aged 36 to 86 years (mean: 59.8 years). Of these, 7 had T2, 41 T3 and 12 T4 tumors based on 1997 AJCC TNM classification. Seven (11.7%) had nodal involvement but none had distant metastasis at diagnosis. Of the 60, 53 (88.3%) were stage III or IV. Prognostic factors and survival were statistically analyzed for 59 cases, excluding the 60th who died of another cause. Follow-up was 4 to 227 months, with a median of 59 months and a mean of 38 months. Of the 59, 48 (81.4%) underwent neoadjuvant chemotherapy (NAC). Survival was estimated using the Kaplan-Meier method as univariate analysis. Cause-specific 5-year survival was 56.8% for all stages, 68.2% for T2, 60.0% for T3, and 41.7% for T4. T stage classification was thus a significant independent prognostic factor in multivariate analysis using Cox's proportional hazards model (p = 0.0240). It also identified T stage classification (p = 0.0486) and NAC (p = 0.0419) as significant independent factors affecting survival with organ preservation. We also statistically analyzed 48 cases treated with NAC, which showed complete response (CR) for 11, partial response (PR) for 25, no change (NC) for 11, and progressive disease (PD) for 1. Responders (CR + PR) showed significantly better survival and organ preservation than nonresponders (NC + PD). The NAC response enables us to predict prognosis. T4 cases without NAC response should be treated intensively.
