title: 6-year experience of concurrent radiochemotherapy with vinorelbine plus a platinum compound in multimorbid or aged patients with inoperable non-small cell lung cancer.
abstract: OBJECTIVE
  Although poor-risk patients represent no minority in inoperable non-small cell lung cancer (NSCLC), there is little experience with concurrent radiochemotherapy (RCT) in this group. Here, the authors report on the feasibility and efficacy of RCT with vinorelbine plus carboplatin or cisplatin in NSCLC patients with comorbidities and poor general health or advanced age.
  
  
  METHODS
  A total of 66 patients (ten women, 56 men, median age 68 years) with inoperable NSCLC and an increased risk of treatment side effects (WHO performance score of 2-3; cardiac, pulmonary or renal failure or extensive weight loss before treatment, or an age of 71-78 years) were treated with vinorelbine 12.5 mg/m(2) on days 1, 8, 15, 29, 36, and 43 in combination with either carboplatin 70 mg/m(2) (n = 59) or cisplatin 20 mg/m(2) (n = 7) on days 1-5 and 29-33 in addition to receiving conventional fractionated radiotherapy with doses of up to 63 Gy (90% isodose).
  
  
  RESULTS
  62 of 66 patients (94%) reached the 90% level of the prescribed radiation dose, and 41/66 patient (62%) received at least two cycles of the platinum compound and four cycles of vinorelbine. The following hematologic side effects (CTC classification [Common Toxicity Criteria]) were observed: grade 3 (12%) and grade 4 (15%) thrombocytopenia, grade 3 (38%) and grade 4 (4%) leukocytopenia, and anemia requiring transfusion (26%). Other side effects (CTC) included grade 3 (3%) and grade 4 (2%) esophagitis and grade 3 pneumonitis (3%). The response rates were as follows: complete remission 18%, partial remission 56%, stable disease 21%, and progressive disease 5%. The cumulative survival rates were 53%, 24%, and 8% at 12 months, 24 months, and 5 years, respectively.
  
  
  CONCLUSIONS
  After including a larger group of patients than in 2003 and following the patients for several years, the authors determine that concurrent RCT consisting of vinorelbine plus a platinum compound and conventional fractionated radiotherapy can be carried out with manageable toxicity, even in this negatively selected population of patients. Their survival rates were comparable to those achieved in other studies with simultaneous RCT.
