Surgery following chemotherapy for metastatic testicular teratoma

A Scottish national mortality study assessing cause of death, quality of and variation in management of patients with testicular non-seminomatous germ-cell tumours. The Scottish Radiological Society and the Scottish Standing Committee of the Royal College of Radiologists

A detailed casenote review was performed on 55 patients registered with testicular non-seminomatous germ cell tumours (NSGCT) between 1983 and 1988 under the Scottish Cancer Registration Scheme and who had died by 1992. Details of all aspects of clinical management relating to their NSGCT and death details were extracted and summarised. An assessment was made on whether the patients' management had been optimal. An analysis of 5 year survival rates by the five Scottish oncology centres demonstrated significant differences between centres (range 70.4-94.2; chi 2 = 14.46, d.f. = 4, P = 0.006). Some patients in all centres were assessed as having received suboptimal treatment, but two centres performed less well than the other three. There is a suggestion that the number of patients treated suboptimally decreases with increasing number of patients seen, but this does not reach statistical significance.

A Scottish national audit of current patterns of management for patients with testicular non-seminomatous germ-cell tumours. The Scottish Radiological Society and the Scottish Committee of the Royal College of Radiologists

A detailed casenote review was performed on all 65 patients registered with testicular non-seminomatous germ cell tumours (NSGCT) during 1989 under the Scottish Cancer Registration Scheme. Details of management at presentation and 2 years following diagnosis were recorded and analysed. In a small number of patients an unacceptable delay in diagnosis was noted. Variation was found in the frequency and type of investigations performed on patients placed on surveillance, types of chemotherapy regimens used and numbers of patients entered into trials. Three per cent of patients had a biopsy of the contralateral testis and 27% of patients defaulted from clinic attendance. Considerable variation in the management of testicular NSGCT in Scotland has been identified. The introduction of management guidelines should result in a more consistent approach to the care of these patients. Support, both financial and psychological, may reduce the unacceptable rate of default.

Failure of salvage treatment in metastatic testicular teratoma

From January 1978 to March 1989, 92 consecutive patients with metastatic testicular teratoma have been treated with cisplatin-based chemotherapy. Thirty seven failed to achieve a complete response, and another four subsequently relapsed. These 41 have required further treatment, consisting of surgery (16 patients), radiotherapy (n = 13) and chemotherapy (n = 12). Surgery was generally used for residual masses where tumour markers were normal, radiotherapy for masses where surgery was not possible or for palliation, and second line chemotherapy was used in patients with raised serum tumour markers or in the presence of multiple inoperable pulmonary metastases. Nine of 16 (56%) patients treated surgically are disease-free, including two who had malignant teratoma in the resection specimen. Three of 13 patients irradiated are disease-free, although two of these three had subsequent excision of residual masses. All 12 patients treated with second-line chemotherapy have died. Surgical excision of residual masses appears to be the most effective way of rendering patients disease-free, providing serum tumour markers are normal. Most of these residual masses will consist of differentiated teratoma or necrosis, but it may be possible to salvage patients with residual malignant disease, providing complete clearance can be achieved. Incompletely resected malignant disease carries a poor prognosis, and incompletely resected disease that is histologically benign will run the risk of subsequent relapse. Radiotherapy provides good palliation but is much less effective than surgery as treatment for residual masses, and should only be used if complete excision cannot be accomplished.(ABSTRACT TRUNCATED AT 250 WORDS)
