摘要: The International Staging System for Lung Cancer provides classification of six levels disease extent in five stage groups that relate to patient management and prognosis. Stage 0 is reserved patients with carcinoma situ. I II definitions provide two completely contained within the lung have different prognostic therapeutic implications. Definitive resection first choice therapy non-small cell cancer these groups. category takes into account erosion survival expectations optimum group T1 T2 as a consequence intrapulmonary lymph node involvement. Although small infrequently encountered disease, classifications may be useful structure investigational programs involving adjuvant surgery. exclusion distant metastases division III extrapulmonary allow selection specific treatment plans. Patients tumors IIIa usually are candidates definitive surgical treatment. specificity T N IIIb categories identifies whom particular radiotherapy plans structured protocol assignments made. It consistent concepts all those classified having IV disease. Implications system surgical, radiotherapeutic, chemotherapeutic regimens rational types. meets requirement simplicity can readily applied broad spectrum clinical teaching environments. is, however, sufficiently reporting results therapies. Prospective use should encourage precision evaluations exploit full refinements imaging technologies. cooperative efforts Task Force on AJCC TNM Committees UICC bring this fruition international acceptance been described. has adopted by others, including Association Study Cancer, Japanese Committee, Spanish Society Respiratory Disease, their official recommendation staging cancer.
