ABSTRACT
Objective To investigate the prognostic significance of N1 stage in non-small cell lung cancer (NSCLC) by comparing is survival with N0 and N2 stages. Methods From Jan. 1982 to Dec. 1994, 138 NSCLC patients with surgical-pathological N1 stage had received complete mediastinal lymph node dissection. Two subgroups of N1 node were identified by using New Regional Lymph Node Classification for Lung Cancer Staging. Their prognostic significances were tested and 5-year survival rates were compared with those of surgical-pathological N0 (307 cases) and N2 (176 cases) patients received radical operation during the same period. Results The overall 5-year suvival rate of N1 patients was 30.4 %. five-year survival was significantly better when N1 involvement was intralobar as compared with extralobar involvement, 50.3 % versus 26.5 % (P=0.001). Intralobar N1 5-year survival was similar to that of N0 (51.4 % vs 50.3 %), and extralobar N1 5-year survival was similar to that of N2 with singl focus (26.5 % vs 23.5 %). Conclusion N1 stage in NSCLC is a compound with two subgroups; the prognostic significance of intralobar subgroup is related to N0 stage and extralobar subgroup is related to that of single focus N2.
ABSTRACT
[Objective] To observe the inhibitory effect of Baihu Decoction (BD) on adverse reaction induced by photodynamic therapy (PT) in malignant tumor patients. [Methods] Fifty-six malignant tumor patients receiving PT were equally randomized into group A and group B. The two groups received routine symptomatic western medicine treatment, and anti-inflammation treatment. Group A was treated with BD additionally. [Results] Incidence of fever was 28.6% and that of pain was 85.7% in group A, and 57.1% and 100% in group B respectively (P 0.05). Duration of fever, pain and edema was respectively 2.73?0.58, 6.71?0.81 and 5.25?0.94 days in group A, and respectively 4.56?0.76, 9.12?1.14 and 8.84?1.01 days in group B (P 0.05). In group A, there were 11 patients with white blood cell (WBC) count over 10?109/L, and the average WBC count was (10.6?2.36)?109/L; there were 18 patients with WBC count over 10?109/L, and the average WBC count was (14.3?3.17)?109/L. The difference of WBC count was significant between groups A and B (P
