Treatment of recurrent disease in lung cancer.

Recurrence is a common event after treatment of lung cancer. Retreatment options depend on previous therapies, location of recurrence, and physical condition of the patient. Locoregional relapse can be treated the same way as initial lung cancer, including surgery, radiotherapy (RT), and chemotherapy (CHT), or combined treatment. Approximately 1% to 2% of all recurrent lung cancer is treated with curative reoperation, with somewhat dismal results. RT has been used for either postsurgical or post-RT locoregional recurrences. In the former case, external beam RT was particularly effective in isolated bronchial stump recurrences, with median survival time of approximately 28.5 months and a 5-year survival of approximately 31.5%. In the latter case, reirradiation, generally with endobronchial brachytherapy, was successful in palliation of intrathoracic symptoms (in at least two-thirds of cases), carrying a low incidence of radiation pneumonitis (up to 5%) although cumulative doses went up to 120-150 Gy. Besides external beam RT, endobronchial RT was used to treat symptomatic intraluminal recurrences, with the vast majority of studies using high-dose rate brachytherapy. Finally, CHT has been used in relapsed/refractory advanced or metastatic non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) with the major emphasis on the third-generation drugs that show good response after previously used platinum-based CHT.     «
