Tumour markers are often circulating tumour-associated indicators of tumour development. As such they are not suitable for tumour screening and localization, but valuable as adjuncts for medical follow-up care of tumour patients, where their serum level alterations may anticipate the clinical detection of tumour behaviour by a lead time of 1 to 6 months before other methods. The following tumour may be controlled by established markers: endocrine tumours by NSE, calcitonin, parathormone, 5-HIAA, catecholamines/metabolites etc.; head-neck tumours: SCC, CEA; thyroid carcinoma: TG, calcitonin; lung cancer: CEA, NSE, SCC; liver cancer: AFP (PLC), CA 19-9 (cholangiocell.), CEA (secondary): biliary tract and pancreatic cancer: CA 19-9; colorectal carcinoma: CEA, CA 19-9; squamous cell carcinoma (ENT, oesophagus, anal): SCC; breast cancer: CEA and CA 15-3; ovarian cancer: CA 125 (epithelial), CA 19-9 (mucinous); germ cell tumours (ovary including trophoblastic tumours/testes): AFP and HCG; prostatic cancer: PAP and PSA; bladder cancer: TPA.

In three new approved indications (non Hodgkin's lymphoma, Hodgkin's lymphoma and acute lymphoblastic leukaemia) and in three previously existing indications (ovarian cancer, soft tissue sarcomas and osteogenic sarcomas), non comparative trials show that ifosfamide can induce tumour regression in patients who relapse after a first course of chemotherapy (sometimes containing cyclophosphamide). But clinical assessment has not yet formally demonstrated that this leads to a significant increase in survival time and/or quality of life, mainly because of toxicity. In cervical cancer, a new indication, a comparative trial shows higher tumour response rates with the ifosfamide + cisplatin combination than with cisplatin alone. However, the greater toxicity of the combination and the lack of any increase in survival must both be taken into account. In breast cancer and lung cancer comparative trials show no difference in efficacy between cyclophosphamide and ifosfamide, while toxicity may be worse with ifosfamide. Ifosfamide has no specific value in these approved indications. The same applied to ENT cancer, against which ifosfamide seems to have little activity.
