  • Adenoid cystic carcinoma (ACC) of larynx is a rare disease, accounting for less than 1% of laryngeal malignancies, These tumors arise almost exclusively in the subglottic and supraglottic regions, while the proportion of glottic ACCs is small. We describe a case of a young man with a subglottis adenoid cystic carcinoma, The patient underwent laryngeal microscopic surgery and radiotherapy, Five years after radiotherapy, local recurrence and distant metastasis Clung and kidney) was detected and he underwent palliative chemotherapy and local treatment. He is still alive for seven years after the initial diagnosis. The treatment strategies for laryngeal ACC are still controversial due to the rarity of the condition. We suggest that multimodality approach may be helpful in deciding a treatment option, and thorough and consistent follow-up for recurrence is mandatory for these patients.

  • 목적 :본 연구에서는 부산대학교병원 치료방사선과에서 성문상부 편평상피세포암으로 진단받고 근치적 방사선치료를 받은 환자들을 대상으로 방사선치료 성적과 여기에 영향을 미칠 수 있는 여러 인자들을 비교 분석하여 성문상부암에서의 방사선치료의 효율성과 역할, 그리고 앞으로의 치료방침의 결정에 있어서 고려해야 할 부분들을 알아보려 하였다. 대상 및 방법 : 1985년 8월부터 1996년 12월까지 성문상부암으로 진단되어 근치적 방사선치료를 받은 환자 32예를 후향적 분석을 통해 최소 29개월간 추적관찰 하였다. 6MV 광자선을 이용하여 조사영역 축소치료법과 통상적 분할조사 방법으로 원발부위와 주위 경부림프절을 평균 70.2 Gy로 치료하였고, 이중 13예는 cisplatin과 5-FU로 유도 항암화학요법을 시행받았다 병기별로는 1기가 5명(15.6$\%$), 2기가 10명(31.3$\%$), 3기가 8명(25$\%$), 4기가 9명(28.1$\%$)이었다. 결과 : 연구 결과 5년 전체 생존율과 국소제어율, 성문보존율은 각각 51.7$\%$, 65.2$\%$, 65.6$\%$였고, 병기별로의 생존율은, 1기, 2기, 3기, 4기 각각 80$\%$, 66.7$\%$, 42.9$\%$, 25.0$\%$였고, 국소제어율은 각각 100$\%$,60.0$\%$, 62.5%$\%$ 44.4$\%$였으며, 성문보존율은 각각 100$\%$, 70$\%$, 62.5$\%$, 44.4$\%$였다. 유도 화학요법을 실시한 군과 방사선 단독 군에서 생존율, 국소제어율 등에서 유의한 차이를 보이지 못했다. 치료실패를 보인 환자 중 7예에서 구제적 수술을 시행했고 이 중 3예에서 성공하였다. 치료 중 화학요법을 병용한 1예에서 중성구감소증으로 입원하였으며, 그 외에는 grade 3 이상의 급성 독성은 관찰되지 않았고, 치료 후 2예에서 심한 후두부종으로 기관절개술을 받았다. 원격전이는 4예에서 보였고(폐 3예, 뇌 1예), 2예에서 이차성 원발암이 발견되었다. T병기와 N병기, 총방사선량, 그리고 종양의 육안적 소견 등이 유의한 예 후인자였다. 결론 . 다른 연구들의 결과와 비교해 보았을 때, 조기 성문상부암인 경우 방사선치료와 보존적 수술이 생존율과 국소제어율에 비슷한 결과를 보이므로 후두기능 보존의 효과가 좋은 방사선치료 단독으로도그 역할을 충분히 할 수 있다 하겠으며, 진행된 병기의 경우에서는 방사선 단독 치료가 수술과의 병합 치료보다 예후가 월등히 좋지 않게 나타나므로 가급적 수술과 방사선치료 병합요법을 시도하는 것이 좋겠으나, 방사선치료를 해야만 하는 경우에서는 성문보존율과 국소제어율을 향상 시킬 수 있는 화학요법과의 병용치료, 특히 동시 화학방사선치료와 다분할 방사선치료, 그리고 방사선 민감제 등을 이용한보다 더 폭 넓은 연구와 치료계획의 수립이 필요하다고 하겠다.

  • Background and Objectives: Occult neck metastasis rate of laryngeal and hypopharyngeal cancer varies widely depending upon authors. Materials and Methods: Sixty four cases, previously untreated, of N0 laryngeal and hypopharyngeal squamous cell carcinoma patients who underwent surgery as an initial treatment from 1992 to 1997 were evaluated. All had unilateral or bilateral elective neck dissection at the time of surgery for the primary. Occult neck metastasis rate was evaluated with pathologic examination of neck dissection specimen. Results: Occult neck metastasis rate by primary site was as follows. Supraglottis ipsilateral 32%(8/25) contralateral 15%(3/20), glottis ipsilateral 17%(5/30), contralateral 0%(0/22), hypopharynx ipsilateral 78%(7/9), contralateral 25%(2/8). Conclusion: Supraglottic and hypopharyngeal cancer may need elective neck treatment bilaterally. Occult neck metastasis of glottic cancer to opposite site was minimal.

  • Voice disorder is classified into three categories, structural, neurogenic and functional dysphonia. Neurogenic dysphonia refers to a disruption in the nerves controlling the larynx. Common examples of this include complete or partial vocal cord paralysis, spasmodic dysphonia. Also it occurs as part of an underlying neurologic condition such as Parkinson's disease, myasthenia gravis, Lou Gehrig's disease or disorder of the central nervous system that causes involuntary movement of the vocal folds during voice production. Functional dysphonia is a voice disorder in the absence of structual or neurogenic laryngeal characteristics. A near consensus exist that Muscle tension dysphonia (MTD) is functional voice disorder wherein hyperfunctional laryngeal muscle activity whereas Spasmodic dysphonia (SD) is neurogenic, action-induced focal laryngeal dystonia including several subtype. Both Adductor type spasmodic dysphonia (AdSD) and MTD may be associated with excessive supraglottic contraction and compensation, resulting in a strained voice quality with spastic voice breaks. It makes these two disorders extremely difficult to differentiate based on clinical interpretation alone. Because treatment for AdSD and MTD are quite different, correct diagnosis is important. Clinician should be aware of the specific vocal characteristics of each disease to improve therapeutic outcome.

  • Basaloid squamous cell carcinoma(BSCC) is a high-grade variant of squamous cell carcinoma, with a prediction for multifocal involvement of the base of tongue, pyriform sinus, supraglottic larynx, hypopharynx and palatine tonsil. It primary affects men in the seventh decade of life with frequent cervical lymph-node metastasis at presentation. Grossly, these tumors are usually firm to hard, with associated central necrosis, occuring as exophytic to nodular masses. Histologically, the this infiltrating tumor offers a variety of growth patterns, including solid, lobular, cribriform, cords, trabeculae, nests and glands or cyst. We present a 55-year-old female who was treated with surgical excision and radiotherapy. She was firstly presented as a recurrent inflammatory neck mass and finally diagnosed with basaloid squamous cell carcinoma in the palatine tonsil.

  • Background and Objectives: To determine if laser endoscopic microsurgery is a reliable and appropriate approach in the treatment of laryngeal carcinomas. Materials and Methods: Retrospective study of 62 patients treated with CO2 laser from June 1988 to November 2000 at Seoul National University Hospital for laryngeal squamous cell carcinoma. All patients were treated with curative intention. Fifty three untreated patients with laryngeal carcinoma (39 glottic and 14 supraglottic carcinoma patients) had primary carbon dioxide laser microsurgery. Nine radiation failure patients were treated. Postoperative radiotheray was done for 17 patients. Neck dissection was performed simultaneously for 4 supraglottic cases with cervical nodal metastasis. Mean follow-up duration was 40 months. Results: In primary laser surgery group, distribution of tumors (American Joint Committee on Cancer, 1997) were 38 cases with Tl, 13 cases with T2, 2 cases with T3. Cure rate was 88.7%(47/53) and local control rate was 92.5%(49/53). Larynx was preserved in 94%(50/53) of patients. The overall 5-year survival rate(Kaplan-Meier) was 81.5%. In radiation failure group, 56% of patients were recurred after laser surgery. Conclusion: Laser surgery could be a better treatment modality for early laryngeal cancers and selected advanced cases. Additional radiation therapy should be considered if resection margin is not satisfactory.

  • Background and Objectives : This study aims to conduct post-voice therapy to patients with unilateral vocal fold paralysis for vocal improvement, motility recovery and analyze the results. Materials and Methods : Voice therapy was conducted to 13 patients who had shown response to voice therapy amongst 98 patients diagnosed with unilateral vocal fold paralysis. In order to be able compare before and after perceptual, acoustic and aerodynamic evaluations were conducted after voice therapy. Also, by using dysphagia checklist, we have verified whether if the patient had dysphagia prior to voice therapy. The therapy was conducted by improving the larynx movement and glottal contact, whilst removing hypertension of the supraglottic. Results : All 13 patients who underwent voice therapy had shown improvements that are statistically significant from 4 scales excluding the S scale from auditory perception evaluation (p<0.05), with enhanced glottal contact. In acoustic evaluation, Jitter, Shimmer and NHR had shown significant improvement after voice therapy. MPT was also notably improved among aerodynamical evaluation (p<0.001). All 11 patients had with dysphagia prior to voice therapy reported to have improved swallowing functions. Conclusion : Application of adequate voice therapy to patients with unilateral vocal fold paralysis, is an effective method that might be employed in the initial phase. Especially, the voice therapy proposed in this study is expected to be useful for patients in hypertension status due to secondary compensation after initial paralysis, since it focuses on improving vocal symptoms in a calm state with the supraglottis sufficiently relaxed. Also, the therapy is expected to be effective for improving swallowing functions.

  • Head and neck cancers are amongst the commonest malignancies, accounting for approximately 20% of the cancer burden in India. The major risk factors are tobacco chewing, smoking and alcohol consumption, which are all preventable. This retrospective study presents data from the histopathology register for a five year period from 2002-2006 at Patna Medical College and Hospital, a tertiary care hospital drawing patients from the entire Bihar state, the 3rd most populous state of India with the majority of the population residing in rural areas. Incidence rates based on sex, age, site of lesion, including age standardized incidence rates for males and females, with mean age of presentation, distribution of histological variants and year wise trend were calculated. Out of 455 head and neck neoplasias, 241 were benign while 214 were malignant. The most common age group for all malignant biopsies was 7th decade for males and the 5th decade for females. Malignant cases were commoner in males than females with the male:female ratio of 3.1:1, which was found to be statistically significant by the chi-square (${\chi}^2$) test. The crude rate and age standardized incidence rate was 0.05 and 0.06 per 100,000 population respectively. Squamous cell carcinoma (SCC) contributed about 96% of all cases, with grade I being the most common. Larynx was the most common site for malignancy, the supraglottic region being its most commonly affected sub-site. This observed incidence patterns in the region are a reminder of widespread unawareness, low healthcare utilization with virtually non-existent cancer programs. It also underlines the need to advocate for reliable cost-effective programs to create awareness, for early detection and plan appropriate management strategies. There is a compelling demand for a cancer registry in this region as well as proper implementation of preventive measures to combat this growing threat of cancer, many of whose risk factors are preventable.

  • Background and Objectives : The purpose of this study was to classify patients with unilateral vocal fold paralysis according to their fixed location and to analysis the effects of two treatment methods by early voice therapy and injection laryngoplasty. Materials and Methods : Twenty patients who were classified as full abduction and slight abduction according to the position of paralysis were treated injection laryngoplasy, and 23 patients were treated by voice therapy. Twenty patients were treated injection laryngoplasy and 23 patients were treated voice therapy. Results were evaluated by acoustic analysis, electroglottography, cepstrum analysis before and after therapy. The voice therapy was conducted by improving the larynx movement and glottal contact, whilst removing hypertension of the supraglottic and use the breathing. Results : Significant improvement was found in the acoustic parameter, cepstrum parameter, and EGG before and after treatment in both groups. There was no significant difference between the two groups when compared before and after treatment to compare the effects of injection laryngoplasty and voice therapy. Conclusion : The initial treatments for unilateral vocal cord paralysis are injection laryngoplasty and voice therapy. however, there is no precise standard about which method should be applied first. Therefore, in this study, we tried to classify patients according to their paralysis position and then apply two methods. The results of this study suggest that voice therapy and Injection laryngoplasty at the initial stage is a very useful method to improve voice quality of vocal fold paralysis and improve laryngeal function.
