[Adjuvant chemotherapy for XXXX ].

After analysing 1929 cases of resection for @entity2 under the classification of adjuvant therapy, histology, stage and chronology, we learned positive points of adjuvant chemotherapy and its problems. The five year survival rate of 45 cases of @entity4153 @entity4318 .9% (oat cell 18.5%, intermediate 28.6%). Long-term survivors are always found among the stage I @entity1 , however, better results (14.7%-60.6%) have been shown since 1980. This fact must be derived from recent achievements of chemotherapy. Seven cases of adjuvant surgery for @entity4153 shows needs of chemotherapy. The randomized controlled study by using @entity7324 for @entity4153 , stage III, and also other studies showed no signs of effectiveness of chemotherapy on @entity4153 . Clinical application of clonogenic cell assay has made an advance in selecting types of chemotherapy. The problems are, however, administration of drugs, i.e. selection of drugs, time and period to administrated, accurate diagnoses and precise judgement of clinical stage and drug tolerance of @entity1 . We expect more effective drugs to come in the near future.
