      P3.01-115 - Liposomal Paclitaxel Versus Gemcitabine: Which is Better? (ID 13299)

      • Abstract


      Lung cancer tends to metastasize to lymph nodes in the early stage.The liposomal Paclitaxel(LP) injection has less side effects and higher uptake.It is also characterized as being able to target to organs with rich reticuloendothelial system and keeping a high concentration for a long time. We assume that LP injection has a better curative effect against NSCLC with regional lymph node metastasis.

      Patients divide to 58 for LP and 56 for Gemcitabine plus cisplatin (GP).Those patients have good comparability in gender,age,ECOG points,pathological pattern,TNM staging and chemotherapy cycles.21 days as a single cycle, each patient finished at least 2 cycles. Estimation was carried on within one week when they have finished the chemotherapy. Chemotherapy Continues if the result turns out CR+PR+SD. surgical treatment would be suggested if the stage of cancer decreases and the lesions of NSCLC turn technically removable. Then continue chemotherapy after surgery, 4 to 6 cycles in total.

      The alleviation rate of lymph nodes metastasis in LP group is significantly higher.The disease control rate of lymph nodes metastasis is 96.551% vs. 92.857%, p=0.38.The alleviation rate of squamous cell carcinoma and the disease control rate is not statistically significant. The alleviation and disease control rate of primary tumor in LP and GP group does not have statistical significance.And among LA patients,it the same trend.
      The LP group has a longer period without disease progression and a higher survival rate in 1 year than the GPgroup.The medium PFS of squamous cell carcinoma in 5 LP group is 8 months which is higher than that in GP group (5.5 months) but does not have statistical significance. The survival rate in 1 year of squamous cell is 50% (16/32).

      The PFS of IIIB stage in LP group is 10 months, significantly higher than GP group(4 months),survival rate in 1 year in LP group is also higher but is not statistically significant.

      As to side effect, the LP group is significantly lower in the incidence of thrombocytopenia, granulocytopenia, anemia and white blood cell reduction.However, the LP group is higher incidence of alopecia.

      Chemotherapy with LP has higher alleviation rate than chemotherapy with GP in treating advanced NSCLC with regional lymph node metastasis, especially for squamous cell carcinoma. The survival rate and PFS in stage IIIB/IV of LP is also higher than that of GP. Meanwhile, LP is able to reduce the incidence rate of side effects such as hrombocytopenia, granulocytopenia,anemia, white blood cell reduction, nausea and vomiting.
