“…More recently, and with the advent of combination chemotherapy, second look surgery (laparoscopy or laparotomy) has been used earlier in the clinical course, to date the time of complete remission and thereby decide the number of cycles of chemotherapy that need to be given (Young et al, 1978;Ozols et al, 1981;Oldham et al, 1982;Raju et al, 1982). There is, however, no evidence to suggest that survival can be increased by use of these techniques, and in addition only scanty evidence exists that combination chemotherapy produces survival that is superior to single agents (Young et al, 1978;Katz et al, 1981;Pereira et al, 1981;Sturgeon et al, 1982;Carmo-Pereira et al, 1982;Vogl et al, 1982;Omura et al, 1983).…”
