title: [Concomitant whole brain radiotherapy and FUDR+VM-26+DDP chemotherapy in brain metastasis of non-small cell lung cancer: a report of short term efficacy].
abstract: BACKGROUND
  To evaluate the efficacy and toxicity of concomitant chemoradiotherapy in patients with brain metastases from non-small cell lung cancer (NSCLC).
  
  
  METHODS
  Thirty patients suffering from NSCLC with brain metastasis were prospectively included in this study. Twenty-four patients had neurological symptoms and an ECOG performance index between 0 and 3. Treatment consisted of concomitant whole brain radiotherapy (WBRT) with a dose of 30 Gy in 15 fractions, followed by a local boosted dose of 20 Gy in 10 fractions for those that the number of the remained lesions were less than 3, or by WBRT with a total dose of 50 Gy for those that the number of the remained lesions were more than 3. Concomitant chemotherapy of FVP regimen with floxuridine 600 mg/(m²*d), teniposide 60 mg/(m²*d), cisplatin 20 mg/(m²*d) on d1 to d5,repeating every 3 or 4 weeks. The response was evaluated by brain CT or MRI after WBRT and 2 cycles of chemotherapy being completed.
  
  
  RESULTS
  All the patients completed WBRT and concomitant chemotherapy including 68 cycles (2 to 4 cycles for each patient). The follow-up rate was 93.3% with a median survival duration of 11.3 months. Total response rate was 46.7%, with CR for 2 and PR for 12. Specific evaluation of brain response demonstrated CR for 8 patients, and PR for 10 patients (the objective brain response rate, 60.0% ). The objective primary disease response rate was 18% for 22 cases of previously untreated primary NSCLC. Other specific evaluation of metastases included 1 PR patient in 6 patients with lung metastases, 3 CR patients and 4 PR patients in 17 patients with lymph node metastases, 1 PR patient with liver metastases, and 1 PR patient with eye metastasis. Twenty four patients with neurological symptoms benefited improvements to different extent. The main adverse effects were myelotoxicity, nausea/vomiting, constipation and alopecia. Grade III and IV toxicities were observed as following: leucopenia (19.1%), anemia (10.3%), thrombocytopenia (7.4%), nausea/vomiting (4.4%), diarrhea (2.9%), alopecia (5.9%), glutamio oxaloacetic transaminase (GOT) and glutamio pyruvic transaminase (GPT) elevation (1.5%). Dehydration therapy was needed at 2 weeks after WBRT in all patients.
  
  
  CONCLUSIONS
  Concomitant WBRT plus FUDR+VM-26+DDP chemotherapy is tolerable in NSCLC patients with brain metastases and the short term response is comparable to the results of others.
