폐암의 자연적 퇴화는 매우 드문 질환이다. 아직 그 기전은 불분명하다. 그러나 신체의 면역반응이 중요한 역할을 하는 것으로 알려져 있다. 이에 본 저자들은 폐의 편평 세포암 환자에서 항암치료 및 방사선 치료 등을 하지 않은 상태에서 자연적 퇴화가 발생한 증례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.
Lung cancer is one of the most prevalent cancers and it has the highest mortality of all forms of cancers. Although surgery, chemotherapy and radiotherapy are routinely used for the treatment of lung cancer treatment, little progress has been made in the treatment of this condition over the past 20 years. The histological subtype of squamous cell carcinoma (SCC) accounts for approximately 30% of all lung cancer patients. Spontaneous regression of non-small-cell lung cancer (NSCL) is an extremely rare phenomenon. Spontaneous regression of cancer (SR) is defined as a complete or partial, temporary or permanent disappearance of all or at least some the relevant parameters of soundly diagnosed malignant disease without any medical treatment or with treatment that is considered inadequate to produce the resulting regression.
