To evaluate the quality of life (QL) in patients with ductal carcinoma in situ of the breast treated with conservative surgery and postoperative irradiation.A self-completed questionnaire covering many disease-, symptom-, and treatment-specific issues was administered to 106 conservatively treated patients affected by non-infiltrating breast cancer. The questionnaire was based on a series of 34 items assessing five main fields of post-treatment adjustment: physical well being, sexual adaptation, aesthetic outcome, emotional/psychological well being, relational behaviour. Furthermore, the patients were requested to evaluate the degree of information provided by the medical staff concerning surgical procedures and radiation therapy, and to evaluate the effects of the treatment on their social and overall life.The questionnaire was completed by 83 patients (78%), who had a median follow-up of 54.5 months. This final sample had a median age of 50 years (range 29-88) at the time of treatment and 54 years (range 32-94) at the time of study. The patients claimed to be in good physical condition. Data relating to sexual life were provided by 93% of the sample. Some limitations in sexuality, some interference with sexual desire, and some modifications during intercourse were reported by 5, 6, and 5 patients, respectively. The subjective evaluations of the cosmetic results of the therapies were generally good. Only 13 patients (16%) reported the perception of a worsened body image. Forty-six percent of the sample (38 patients) declared that they felt tense, 48% (39 patients) nervous, 29% (38 patients) lonely, 59% (41 patients) anxious, and 41% (34 patients) depressed. Only seven patients (8%) declared that the treatment had had a bad effect on their social life, and 15 (18%) thought that their current life had been affected by the treatment. The amount of information received concerning the disease and treatment (surgery and radiotherapy) was considered sufficient by 79%, 75%, and 79% of the sample, respectively.This study revealed a good QL in patients treated with breast conservation and postoperative irradiation, with a preserved favourable body image and a lack of negative impact on sexuality. Radiation therapy did not lead to any significant additional problems capable of affecting the QL.

The optimal treatment of ductal carcinoma in situ (DCIS) of the breast has not yet been established. The effectiveness of adjuvant postoperative radiotherapy after conservative surgery is debated. Few data are available in Italy on the combined treatment. A collaborative multi-institutional study on this issue in 10 radiation oncology departments of the north-east of Italy was conducted. One hundred and thirty nine women with DCIS of the breast were treated between 1980 and 1990. Age ranged between 28 and 88 years (median 50 years). Surgical procedures were: quadrantectomy in 108, lumpectomy in 22 and wide excision in 9 cases. The axilla was surgically staged in 97 cases: all the patients were node-negative. Radiation therapy was delivered with 60Co units (78%) or 6 MV linear accelerators (22%) for a median total dose to the entire breast of 50 Gy (mean 49.48 Gy; range 45–60 Gy). The tumour bed was boosted in 109 cases (78%) at a dose of 4–30 Gy (median 10 Gy) for a minimum tumour dose of 58 Gy. Median follow-up was 81 months. Thirteen local recurrences were recorded, 7 intraductal and 6 invasive. All recurrent patients had a salvage mastectomy and are alive and free of disease. Actuarial overall, cause-specific and recurrence-free survival at 10 years are of 93%, 100% and 86%, respectively. The results of this retrospective multicentric study substantiate the favourable data reported in the literature and confirm the efficacy of the breast-conserving treatment of DCIS employing conservative surgery and adjuvant radiation therapy.

Purpose To evaluate the outcome of pts treated with Breast-Conserving Surgery (BCS) and definitive irradiation (DR) for Ductal Carcinoma in situ of the breast (DCIS). Patients and methods 110 cases (104 evaluable) treated between 1980 and 1990 have been collected in 9 Italian Institutions. All the cases were treated with BCS (quadrantectomy 78, wide excision 8, tumorectomy 18) and DR (median breast total dose 50 Gy, median boost dose 10 Gy). Results Median follow up time was 62 months (range 21–151). There were 6 (5.7%) failures in the breast. Neither nodal recurrences or distant metastases were observed. All the 6 patients were salvaged with mastectomy. Five metachronous controlateral breast tumors (2 invasive) and 4 second tumors developed during follow-up. Five-year actuarial overall, cause specific and breast-recurrence free survival is 94.6%, 100% and 90% respectively. Conclusion This study confirm that RCS and DR is an effective alternative to mastectomy in the treatment of DCIS of the breast.

Because of its physical and potassium-metabolic characteristics 201T1 is more suitable than 131Cs for radioisotopic studies of the cold thyroid nodule, with the further diagnostic possibility of quantitatively assessing intranodular behaviour for a specific differentiation among different kinds of neoformations. Using a gamma-camera on line with a computer data processing device, sequential scintiscans were recorded for the first 20-30 min after i. v. administration of 15-20 MCi\lkg of radiothallium; delayed sequences were taken at 40-60 min if intranodular uptake appeared. A quantitative appraisal was made of the differential 201Tl uptake-ratio between nodule and healthy thyroid tissue (density-index) and the multiparameter analysis of thyroid time/activity curves generated on the relative regions of interest (ROIs). This computerized study, in 120 out of 293 patients submitted to this radiothallium test, has shown a) diagnostic agreement between clinical-histological and radioisotopic findings in 76 out of 79 colloid-cystic or degenerative neoformations, in all 16 malignant and in 23 out of 25 hyperplastic benign nodules; b) significant statistical difference of the density-index in solid versus cystic but not between benign and malignant nodules; c) different 201T1 kinetics behaviour in different kinds of solid thyroid lesions with a satisfactory statistical difference of the radiothallium nodular dissapearance-index.

Aims and Background In spite of the fact that ductal carcinoma in situ (DCIS) of the breast is a frequently encountered clinical problem, there is no consensus about the optimal treatment of clinically occult (i.e., mammographic presentation only) DCIS. Interest in breast conservation therapy has recently increased. Few data are available in Italy on the conservative treatment with surgery and adjuvant postoperative radiotherapy. Methods A retrospective multi-institutional study was performed in 15 Radiation Oncology Departments in northern Italy involving 112 women with subclinical DCIS of the breast treated between 1982 and 1993. Age of the patients ranged between 32 and 72 years (median, 50 years). All of them underwent conservative surgery: quadrantectomy in 89, tumorectomy in 11, and wide excision in 12 cases. The most common histologic subtype was comedocarcinoma (37%). The median pathologic size was 10 mm (range 1 to 55 mm). Axillary dissection was performed in 83 cases: all the patients were node negative. All the patients received adjunctive radiation therapy with 60Co units (77%) or 6 MV linear accelerators (23%) for a median total dose to the entire breast of 50 Gy (mean, 49.48 Gy; range, 45-60 Gy). Seventy-six cases (68%) received a boost to the tumor bed at a dose of 8-20 Gy (median 10 Gy) for a minimum tumor dose of 58 Gy. Results At a median follow-up of 66 months, 8 local recurrences were observed, 4 intraductal and 4 invasive. All recurrent patients had a salvage mastectomy and are alive and free of disease at this writing. The 10-year actuarial overall, cause-specific, and recurrence-free survival was of 98.8%, 100%, and 91%, respectively. Conclusions The retrospective multicentric study, with a local control rate of more than 90% at 10 years with 100% cause-specific survival, showed that conservative surgery and adjuvant radiation therapy is a safe and efficacious treatment for patients with occult, non-palpable DCIS.
