비강/부비동암 (Nasal Cavity/Paranasal Sinus Cancer): Comprehensive Overview for Medical Professionals

개요 (Overview)

비강 및 부비동암은 비강과 주변 부비동(상악동, 사골동, 전두동, 접형동)에서 발생하는 악성 종양입니다. 이 부위의 암은 비교적 드물며, 다양한 조직학적 아형이 있습니다. 가장 흔한 형태는 편평세포암(squamous cell carcinoma)입니다.

Nasal cavity and paranasal sinus cancers are malignant tumors that arise in the nasal cavity and surrounding paranasal sinuses (maxillary, ethmoid, frontal, and sphenoid sinuses). These cancers are relatively rare and encompass a variety of histological subtypes, with squamous cell carcinoma being the most common type.

9. Genetic Predisposition: Family history and genetic mutations.

10. Chronic Sinusitis: Chronic inflammation and irritation.

발생빈도 (Incidence)

비강 및 부비동암은 두경부암 중에서 발생 빈도가 낮습니다. 전 세계적으로 드물며, 주로 50세 이상의 남성에서 발생합니다.

Nasal cavity and paranasal sinus cancers are rare among head and neck cancers. They are uncommon worldwide and primarily affect men over the age of 50.

임상증상 (Clinical Presentation)

1. 코막힘 (Nasal Obstruction): 지속적인 코막힘.

2. 코피 (Epistaxis): 자주 발생하는 코피.

3. 안면 통증 (Facial Pain): 얼굴 부위의 통증.

4. 시력 변화 (Visual Changes): 시력 저하 또는 복시.

5. 안면 부종 (Facial Swelling): 얼굴의 붓기.

6. Nasal Obstruction: Persistent nasal blockage.

7. Epistaxis: Frequent nosebleeds.

8. Facial Pain: Pain in the facial region.

9. Visual Changes: Decreased vision or double vision.

10. Facial Swelling: Swelling of the face.

진단 (Diagnosis)

1. 임상 평가 (Clinical Evaluation): 철저한 두경부 검사 및 병력 청취.

2. 영상 검사 (Imaging Studies):

   • CT/MRI: 종양의 크기와 침범 범위를 평가.
   • PET/CT: 원격 전이 평가.

3. 내시경 검사 (Endoscopy): 비강과 부비동의 직접적인 시각화 및 생검.

4. Clinical Evaluation: Thorough head and neck examination and history taking.

5. Imaging Studies:

   • CT/MRI: Assess the size and extent of the tumor.
   • PET/CT: Evaluate for distant metastases.

6. Endoscopy: Direct visualization and biopsy of the nasal cavity and sinuses.

병리조직 (Pathology)

• 조직학적 유형 (Histological Types): 편평세포암이 가장 흔함. 그 외에도 선암, 소세포암, 유암종, 점액표피암 등 다양한 아형이 존재.

• 면역조직화학 (Immunohistochemistry): 종양의 기원과 특성을 확인.

• Histological Types: Squamous cell carcinoma is the most common. Other types include adenocarcinoma, small cell carcinoma, adenoid cystic carcinoma, and mucoepidermoid carcinoma.

• Immunohistochemistry: To confirm the origin and characteristics of the tumor.

영상검사 소견 (Imaging Findings)

• CT/MRI 소견 (CT/MRI Findings): 종양의 크기와 위치, 주변 조직 침범 평가.

• PET/CT 소견 (PET/CT Findings): 대사 활동을 통해 원격 전이 평가.

• CT/MRI Findings: Evaluate the size, location, and invasion of surrounding tissues by the tumor.

• PET/CT Findings: Assess metabolic activity to evaluate distant metastases.

수술 (Surgery)

• 적응증 (Indications): 주로 초기 및 국소 진행성 종양에 사용.

• 목표 (Goal): 종양의 완전 절제 및 기능 보존.

• 기술 (Techniques): 광범위 절제술, 내시경 수술, 목 림프절 절제술.

• Indications: Mainly used for early and locally advanced tumors.

• Goal: Complete resection of the tumor and preservation of function.

• Techniques: Wide local excision, endoscopic surgery, neck dissection.

방사선치료 (Radiation Therapy)

1. 적응증 (Indications): 수술 후 보조 치료, 국소 진행성 또는 재발성 질환.

2. 기술 (Techniques):

   • 강도 변조 방사선 치료(IMRT) (Intensity-Modulated Radiation Therapy): 정확한 종양 표적화.

3. 선량 (Dose):

   • 원발 종양 (Primary Tumor): 60-70 Gy.
   • 림프절 (Lymph Nodes): 50-60 Gy.

4. Indications: Adjuvant therapy post-surgery, locally advanced or recurrent disease.

5. Techniques:

   • Intensity-Modulated Radiation Therapy (IMRT): Precise tumor targeting.

6. Dose:

   • Primary Tumor: 60-70 Gy.
   • Lymph Nodes: 50-60 Gy.

항암제 (Chemotherapy)

1. 적응증 (Indications): 방사선 치료와 병행하거나 전이성 질환에 사용.

2. 약제 (Agents): 시스플라틴, 5-플루오로우라실, 세툭시맙.

3. 프로토콜 (Protocols): 동시 화학방사선 치료 (CCRT), 보조 화학요법.

4. Indications: Used concurrently with radiation therapy or for metastatic disease.

5. Agents: Cisplatin, 5-fluorouracil, cetuximab.

6. Protocols: Concurrent chemoradiotherapy (CCRT), adjuvant chemotherapy.

예후 (Prognosis)

1. 5년 생존율 (5-year Survival Rate): 약 30-50%.
2. 국소 재발율 (Local Recurrence Rate): 약 30-40%.

The prognosis for nasal cavity and paranasal sinus cancer is generally poor, with a 5-year survival rate of approximately 30-50%. The high rate of local recurrence, about 30-40%, underscores the need for aggressive treatment and close follow-up.

비강 및 부비동암의 예후는 일반적으로 좋지 않으며, 5년 생존율은 약 30-50%입니다. 약 30-40%의 높은 국소 재발율은 공격적인 치료와 철저한 추적 관찰의 필요성을 강조합니다.
