  • Background: Cervical metastasis of unknown origin is defined as histologic evidence of malignancy in the cervical lymph nodes with no apparent primary site of origin for the metastatic tumor. Patients and Methods: A retrospective review of 20 cervical metastasis of unknown origin diagnosed and managed between january 1989 and December 1999 at the Korea University was undertaken to determine outcome. Patient age ranged 46 to 78 years (mean 60). There were 17 men and 3 women. The aim of this study is to ananlyze the diagnostic approach and the result of treatment of the cervical metastasis of unknown origin. Result: Histopathologically, squamous cell carcinoma (15 case, 75%) were the most common, followed by adenocarcinoma (4 case, 20%), undifferentiated carcinoma (1 case, 5%) According to the criteria of the AJCC on staging, N1 was 2 cases, N2a 2 cases, N2b 5 cases, N2c 1 cases, N3 10 cases. Overall survival rate for all patients at 2 years was 45% and 5 years 25%, and in the combination therapy(surgery and radiotherapy group (12 cases)) it was 67% and 34% respectively, high compared with other treatment modality such as surgery or radiotherapy alone. In extracapsular spread positive group, 5 year survival rate was 12%, but was 33% in the extracapsular spread negative group. Conclusion: With no stastatical significance, extracapsular spread group was poor outcome in our study. Combination of radiotherapy and surgery was more effective treatment result than surgery alone or radiotherapy alone in our study. But, overall prognosis of cervical metastasis of unknown origin was very poor despite aggressive treatment (5 year survival rate: 25%).

  • 미세외과 수술에 의한 유리 피판술의 도입은 두경부 종양제거후 재건에 괄목할 만한 진보를 가져왔다. 특히 광범위한 종양의 제거가 필요하며 인근의 조직으로 수복이 어렵고 기능 및 외모상의 재건이 문제가 되는 경우 유리 피판은 절대적인 적응이 된다. 구강은 언어구사 와 연하(deglutition)기능을 담당하므로 재건을 위해서는 얇고 부드러운 조직으로 수복하여 주어야 한다. 전완부 유리피판은 혈관경의 위치가 대부분 일정하고 종양 제거후 결손의 모양에 따라 피판을 계획할 수 있기 때문에 구강암 제거후 가장 많이 이용되는 유리피판이다. 저자는 1982년 부터 1988년까지 영국 글라스고우 소재 서부 스코틀랜드 성형 및 구강외과 병원에서 구강의 편평상피암환자로 암종제거 후, 전완부 피판에 의한 재건 및 방사선 치료를 받은 151명의 치료결과(재발율 및 생존율)를 분석하였다. 절제연의 종양조직의 양성(P<0.05), 경부 임파절의 extracapsular node spread여부(P<0.001), 경부 임파절 곽청술의 종류(P<0.05) 등은 재발율과 관련하여 통계적으로 유의하였다. 반면에 종양의 구강내 위치, 하악골의 침범여부등은 통계적의의가 없었다. 생존율에 관하여는 종양의 구강내 위치 (P<0.05), 종양절제연 종양여부(P<0.005), 하악골의 침범여부(P<0.05), 경부 임파절의 extracapsular node spread여부(P<0.001) 등이 통계적으로 유의할 만한 요소로 밝혀졌다. 젊은 나이의 환자들에서(50세이하) 특징적으로 높은 사망률을 보였다. 하악골절제방법의 차이는 환자의 생존예후에 통계적으로 유의할 만한 영향을 주지 못했다.

  • Backgrounds : To evaluated the use of FDG PET/CT for the identification of extracapsular spread(ECS) with histologic correlation in laryngeal cancer. Methods : We reviewed 79 medical records of patients who underwent of FDG PET/CT for laryngeal cancer before surgery. Results : ECS was present in 41.9%(18/43) dissected necks and in 34.5%(20/58) dissected cervical levels. There was a significant difference in the SUVmax between cervical lymph nodes with ECS and without ECS($6.39{\pm}4.53$ vs. $1.19{\pm}1.64$, p<0.001). The cut-off value for the SUVmax for differentiating with ECS from without ECS was 2.8 with the sensitivity of 85.7% and the specificity of 85.6%. Conclusion : The median SUVmax cut-off values of FDG PET/CT higher than 2.8 was associated with greater risk cervical lymph node metastasis with ECS in patients with laryngeal cancer.

  • The indolent course of most thyroid papillary carcinomas, even the presence of regional lymph node metastasis, make them unique among human malignant head and neck cancers. Age, sex, extracapsular invasion and anaplastic change are known to be correlated with prognosis. The purpose of this study is to clarify the significance of DNA content analysis as a prognostic factor. Twenty five thyroid papillary carcinomas were possible to be examined by flow cytometric analysis using fresh surgical specimens and three nodular hyperplasias and seven follicular adenomas were included as control group. The results were as follows: l) All of twenty five thyroid papillary carcinomas showed diploidy. 2) S-phase fraction was $1.94{\pm}2.77%$ in normal control group and $2.60{\pm}2.66%$ in papillary carcinoma group. The proliferation index was $8.44{\pm}3.89%$ in normal control and $7.70{\pm}3.63%$ in papillary carcinoma group with even low value. 3) Age, sex, extracapsular spread and lymph node metastasis showed no significant difference. In conclusion, low proliferative activity of thyroid papillary carcinomas are thought to be related with good prognosis.

  • Elective neck dissection (END), provide proper information on nodal status and stage which are significant prognosticator in head and neck cancers with clinically $N_{(0)}$ neck. But there are many controversies for the extents, methods of surgery, moreover, whether normal lymph nodes, local defencer, have to be removed or not. The authors performed 47 END in 39 patients of head and neck squamous cell carcinoma from 1984 to 1989 and a retrospective study of the cases was conducted. Eighteen percent of nodal metastasis and five percent of extracapsular spread were found in END specimens. We concluded that END provide significant information for the management and evaluation of prognosis in head and neck cancer.

  • Background: The author analyse the impact of extracapsular lymph node spread and bone engagement in the ipsilateral neck of patients suffering squamous cell carcinoma (SCC) of the lower lip. Methods: The data of 56 neck dissections performed in patients suffering SCC of the lower lip between January 2000 and December 2008 were retrospectively analysed. Statistical analysis was performed with the Kaplan-Meier life table method, and the survival rate was investigated with the log rank statistic and significance test. The values were considered statistically significant at p<0.05. Results: Nine patients took advantage from simultaneous treatment of tumor and prophylactic neck dissection (level I-III), reaching 100% survival rate. Patients suffering metastasized disease, who received radical neck dissection at the time of tumor treatment, presented 83.3% survival rate. Patients who underwent previous surgery and radiotherapy presented worse prognosis although radical neck dissection in case of extra-capsular spread only (24.7%) and osseous engagement (22.2%). Conclusion: Prophylactic neck dissection (level I-III) is recommended in T3-T4 N0 SCC. Simultaneous treatment of tumor and cervical lymph nodes provides a better prognosis as respect to delayed nodal management. Extra-capsular spread with or without bone engagement represents independent risk factor responsible for high mortality rate of SCC of the lower lip.

  • When thyroid carcinoma invades the larynx or trachea, the proper treatment is needed because of significant morbidity and mortality due to airway obstruction. Hemoptysis and dyspnea are the result of intraluminal extension of the tumor and call for immediate investigation with endoscopic examination and CT. If the thyroid carcinoma with extracapsular spread invades only outer perichondrium of the tracheal or laryngeal cartilage, the shaving operation would be sufficient, but if the tumor invades the cartilage or if there is intraluminal invasion, it is mandatory to remove partial or total part of some aerodigestive tract structures. We retrospectively analyzed 14 surgical cases of the thyroid cancer with laryngotracheal invasion(12 papillary carcinomas and 2 anaplastic carcinomas) at the Department of Otorhinolaryngology-Head and Neck Surgery, Seoul National University Hospital. The analysis was focused on clinical manifestation, pathologic findings, types of management and results. Survival result was not adequately analyzed due to some recently operated cases.

  • Objective: We aimed to define clinicopathologic risk factors associated with regional recurrence (RR) and thus the effectiveness of postoperative radiotherapy (PORT) for neck control for head and neck squamous cell carcinomas (HNSCCs) with differing cervical lymph node status. Methods: A retrospective study was performed in 196 HNSCC patients with pathologically positive neck node (N+) to evaluate the high-risk factors for RR and to define the role of PORT in control after neck dissection and postoperative radiotherapy (PORT). Results: Overall, the RR rate after neck dissection and PORT was 29%. Extracapsular spread (ECS) was confirmed to be the only independent risk factor for RR. There were no significant risk factors associated with RR in the ECS- group. The 5-year disease-specific survival rate was 45%, which descended to 10% with the emergence of RR. Conclusions: ECS remains a determined risk factor for RR after neck dissection and PORT in patients with N+. PORT alone is not adequate for preventing RR in the neck with ECS after neck dissection. More intensive postoperative adjuvant therapies, especially combined chemotherapy and radiotherapy, are needed to prevent regional failure in HNSCC patients with ECS.
