In order to assess the effect of the no-touch isolation technique, in the treatment of large bowel cancers, on the site of first recurrence and disease-free and overall survival, 236 patients were prospectively and randomly assigned to either the no-touch isolation technique (117 patients) or to a conventional resection technique (119 patients). No patient with distant metastases or unresectable disease entered the study. The two treatment groups were comparable with regard to patient characteristics. Pre- and postoperative complications (including mortality within 30 days) were similar in both groups. After a complete follow-up of 5 years, a tendency for reduction in the number of, and time to, occurrences of liver metastases was seen in the no-touch isolation group (P = 0.14). This effect was most obvious in the sigmoid colon with angio-invasive growth. Overall (P = 0.42) and corrected (P = 0.25) survival did not differ significantly among the treatment groups although in every analysis the survival data of the no-touch isolation group were superior. The data do suggest a limited benefit of the no-touch isolation technique. This observation is important since the morbidity and mortality of surgery were equal in both groups.
We studied changes in staging and treatment of patients with early breast cancer (TNM stage I and II) in eight community hospitals in southeast Netherlands between 1984 and 1991 and related these changes to the guidelines for the management of breast cancer drawn up by the regional Breast Cancer Study Group. Since 1984, the proportion of patients that underwent breast-conserving therapy (local tumour excision, axillary dissection, and irradiation of the breast) increased from 26% to 53%. Although the mean number of axillary lymph nodes examined by the pathologists increased significantly, the proportion of patients with positive lymph nodes remained unchanged. The proportion of patients with involved axillary nodes receiving any form of adjuvant systemic therapy increased from 49% to 82%. Therapeutic policy initially varied significantly from one hospital to another but gradually became more uniform. We conclude that, except for elderly patients, treatment of early breast cancer corresponded increasingly to the guidelines of the regional Breast Cancer Study Group.
Both short and long term survival improved considerably in all age groups. This improvement was most marked for patients who were diagnosed with a localised tumour. Patients who survive for 19 years may be considered cured.
This study evaluates the usefulness of routine follow-up of breast cancer patients. In all, 416 patients who were treated with curative intent for breast cancer were followed according to a fixed follow-up schedule for a minimum of 2.5 years and a maximum of 13.5 years (mean about 5 years). During the 4533 routine out-patient visits, 4116 chest radiographs, 3889 pelvic radiographs and about 17,000 laboratory tests were carried out routinely. In the follow-up period, 148 patients were found to have distant recurrence of whom 34 (23 per cent) had asymptomatic metastases and 114 symptomatic metastases. Of the 8005 routinely performed radiographs, 24 (0.3 per cent) revealed asymptomatic metastases, and the 17,000 laboratory tests led to the discovery of six asymptomatic bone and four asymptomatic liver recurrences. Screening for metastases did not result in a reduction of the lead time to the diagnosis of asymptomatic metastases; the disease-free interval was equal in both symptomatic and asymptomatic patients. Of the 46 locoregional recurrences 42 were found by physical examination during a routine follow-up visit and 37 had not been noticed by the patient. Seventeen second primary breast cancers were diagnosed, six of which were in stage I (less than 2 cm). Mammography was not a part of the routine follow-up scheme. It is concluded that routine follow-up of breast cancer patients by history and physical examination is sufficient to detect local recurrence and a second primary tumour as well as giving the opportunity to track signs and symptoms of distant recurrence at an early stage. Performing annual or biannual mammography is advisable, but the use of other costly routine investigations in the follow-up is not justifiable, as no therapeutic advantages can be expected.
