Background: A randomised trial was conducted comparing wide lumpectomy and breast irradiation with modified radical mastectomy. As the follow-up was long (mean duration 22 years), we analysed the variation in the effect of treatment over time., Patients and Methods: The trial included 179 patients with a breast cancer measuring

Background: Analyses of predictive factors for local recurrences are important, as an increasing number of patients with early breast cancer opt for a breast-conserving procedure. This study investigates whether factors predictive of local recurrence differ between patients treated with conservative or radical surgery., Patients and Methods: Two thousands and six patients with invasive breast carcinoma (< or =25 mm) were included. Of these patients, 717 were treated conservatively (lumpectomy and breast irradiation) and 1289 were treated with total mastectomy. All patients had axillary dissection and received lymph node irradiation if axillary nodes were positive. Most patients did not receive adjuvant chemotherapy or additive hormonal treatments. The mean duration of follow-up was 20 years. The main end point was the total local recurrence rate. The risk factors of local recurrence were estimated by multivariate analyses and interaction tests were used for intergroup comparisons., Results: Statistically significant predictive factors for mastectomized patients were histological grade, extensive axillary node involvement (10 nodes or more), and inner quadrant tumors, which were of borderline significance. Young age, however, was not a prognostic indicator for local recurrence. The main statistically significant factor for patients treated with a conservative approach was young age (< or =40 years). These younger patients had a five-fold increased risk of developing a breast recurrence compared with patients older than 60 years., Conclusions: Younger patients with early breast cancer treated with breast-conserving surgery should in particular be followed up at regular intervals so that any sign of local failure can be diagnosed early.

Background: The authors analyzed the outcome of patients with early-stage breast carcinoma after an isolated local recurrence, taking into account initial tumor characteristics and the type of initial treatment and local salvage treatment., Methods: One hundred five patients were studied who presented with a breast tumor measuring

The aim of this study is to determine the diagnostic value of magnetic resonance imaging in the diagnosis of local recurrence of breast cancer. From 1991 to 1994, 61 women were studied prospectively using magnetic resonance imaging. All examinations were made on a 1.5 Testa machine with T1 weighted images and after gadolium-dota injection and dynamic images (T1 weighted sequences every 47 seconds during injection of a gadolinium-dota bolus). All the pre-injection, images in the dynamic series were subtracted from the images after injection. A surgical biopsy was obtained in 39 patients yielding a diagnosis of local recurrence (n = 28) or a benign lesion (n = 11). Among the 28 local recurrences, pathology examination reported invasive cancer in 22 and intra-ductal carcinoma in 6. In 22 patients with normal magnetic resonance imaging, follow-up examinations were performed every 6 months. There were no local recurrences within a delay of 6 to 36 months. Twenty-six of the 28 patients with a local recurrence, cystosteatonecrosis and surgery scar tissue less than 6 months old showed contrast uptake 1 min and 34 s after gadolinium injection during the dynamic sequence. This product uptake yielded nodular images within the invasive carcinomas and linear images in the intraductal cancers. In all cases, it is easier to visualize this contrast uptake in subtraction images. In conclusion, magnetic resonance imaging is a simple reliable method for the diagnosis of local recurrence of breast cancer.
