Purpose

To evaluate prior compliance with guidelines in patients treated with salvage chemotherapy for advanced germ-cell tumours (GCT).

Patients and methods

Data concerning the initial management of patients requiring salvage chemotherapy for GCT at Institut Gustave Roussy between 2000 and 2010 were obtained and correlated with recommendations for treatment. Criteria of non-compliance were defined based on guidelines. Compliance with guidelines, predictive factors for non-compliance and the impact on outcome were analysed.

Results

Among 82 patients treated in the salvage setting, guidelines to initial treatment were followed in only 41 cases (50%). The most common non-compliance criteria were non-adherence to the planned dose (16%), an inappropriate interval between first-line chemotherapy cycles (16%), the lack of post-chemotherapy surgery (16%) and a long interval to post-chemotherapy surgery (48%). Compliance with standard care was better in cancer centres than in other hospitals (private or public) (Odd Ratio (OR): 6.9, P = 0.001). A poor-risk status according to the International Germ Cell Cancer Collaborative Group (IGCCCG) was also predictive of compliance in univariate but not in multivariate analysis. No significant difference in outcome after salvage chemotherapy was observed. Patients relapsing after non-compliant first-line therapy tended to be more easily salvaged, which is consistent with the fact that their initial treatment was inadequate. Some of these relapses were therefore probably not due to true biologically refractory disease.

Conclusion

Guidelines for first-line treatment are adhered to in only half the patients requiring salvage chemotherapy. As the only predictive factor for non-compliance was the treating centre, centralisation of patients with GCT in well-trained hospitals should be recommended.
