When relapse occurs six months after the end of the first line chemotherapy, the usual practice is to reintroduce the first-line treatment. This is based on old studies where the number of patients included was low. If the interval of time after the first line of treatment is ≥ three months, two second-line treatment strategies are possible resumption of initial chemotherapy or topotecan. The combination of cisplatin with etoposide have shown high response rate, whatever the time of relapse. There are, however, no randomized study in the literature comparing topotecan to the reintroduction of a platinum salt associated etoposide.
