癌瘤外科在外科领域有其本身的特殊性。目前,癌瘤外科的一些理论性问题尚在探索之中;实践中已经比较明确的道理亦未引起足够的重视。笔者在临床上曾观察到由于频繁触诊促使乳癌扩散转移的病例;还有手术后切口下方、盆腔癌瘤播散,淋巴结扩散和血行转移病例;也有因麻醉和手术方法选择不当或采用单纯手术治疗而在短期内恶化病例。因此,本文拟对癌瘤外科的几个问 Cancer surgery has its own particularities in the surgical field. At present, some theoretical problems in cancer surgery are still being explored; in practice, relatively clear truth has not attracted enough attention. In the clinic, the authors have observed cases of breast cancer spread and metastasis due to frequent palpation; there are cases of post-operative incisions, spread of pelvic cancer tumors, spread of lymph nodes, and hematogenous metastasis; there are also cases of improper choice of anesthesia and surgery or surgery alone. Treatment worsens in the short term. Therefore, this article proposes several questions for cancer surgery.
