Materials and Methods
The end results illustrating the revised stage grouping rules were derived from a collected series of patients. Clinical, surgical-pathologic, and follow-up information on 1,524 consecutive, previously untreated, patients who received their primary treatment for non-small cell lung cancer at the University of Texas M. D. Anderson Cancer Center from 1983 through 1988 was combined with a previously published classification research database5 (Table 1). In the duration covered by the collected
Prognostic Implications of Stage Grouping
Stage grouping (Table 3) involves the concept of combining subsets of patients classified according to TNM descriptors into categories or stages, each having generally similar treatment options and survival expectations. This classification hierarchy is useful for end results reports, particularly investigations involving small numbers of patients, and for rapid recall of the prognostic implications of various levels of the anatomic extent of disease. In the International Staging System schema,
Stage Grouping of the TNM Subsets
The revised stage grouping rules divide stage I and stage II into A and B categories and modify stage IIIA to more accurately represent the prognostic implications of the anatomic extent of disease in each TNM subset. The T1N0M0, T2N0M0, and T1N1M0 anatomic subsets are designated as separate entities, and the T3N0M0 category is placed in stage IIB, which is consistent with the end results for this group (Table 3).
The end results according to clinical (Table 8, top) and surgical (Table 8, bottom)
