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.

Radiotherapy patients are at risk of developing leukopenia, which risk depends on the irradiated volume, the rate of irradiated bone marrow and the radiation dose. Radiogenic leukopenia may cause radiotherapy drop-out, with consequent effects, on local tumor control and clinical outcome. The introduction of granulocyte growth factors, such as filgrastim, has permitted to accelerate normal neutrophil count recovery in irradiation-related neutropenia both in vitro and animal models; clinical experience in humans is still lacking, relative to both indications and scheduling. In the Oncologic Radiotherapy Department of Treviso Hospital, 31 patients irradiated for Hodgkin disease, rectal cancer and other malignancies, who presented leukopenia requiring treatment discontinuation, were given filgrastim to assess its actual effect in avoiding further drop-outs and to compare two administration schedules (2 or 3 vials, 30 MIU, weekly). Filgrastim treatment was continued throughout the radiotherapy cycles, for 1 to 5 weeks. Eighteen patients had received previous chemotherapy and 11 were undergoing concurrent 5-fluorouracil chemotherapy-irradiation. A mean 203% increase in leukocyte count was observed (136% in the patients treated with 2 vials/week and 274% in those receiving 3 vials/week); this increase was more apparent in women that in men (256% versus 91%) and slightly higher in patients 50 years old and with target volumes5000 ml. Filgrastin treatment was well tolerated by all patients, with no discontinuations due to adverse effects; 9 patients (29%) reported skeletal pain, which was marked in 2 of them only. Eighty percent of patients completed all the radiotherapy cycles with no discontinuation, while 6 patients dropped out because leukopenia persisted. Biweekly filgrastim administration was effective to prevent unscheduled radiotherapy discontinuation in 75% of patients and triweekly administration was effective in 86% of patients. In our experience, filgrastim administration was well tolerated and effective in decreasing the irradiation drop-outs caused by treatment-related leukopenia. Since this drug is rather expensive, we decided to use routinely the lower dosage of biweekly administration (with one vial given on Friday and Saturday, to permit neutrophil recovery during the day off) and to reserve the higher dosage (3 vials a week) to the patients with large body areas, big target volumes and persistent leukopenia during previous chemotherapy.

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.

Radiotherapy-related mucositis is the most frequent complication in the patients submitted to irradiation for head and neck cancers. Many such patients may develop mycotic infections which may lead to treatment discontinuation, with possible consequences on the local control of these cancers. In this study, we investigated the efficacy of fluconazole in preventing mycotic mucositis in 80 patients undergoing radiation therapy for head and neck cancers. The patients were randomized to two groups: 41 patients in group A received the supporting treatment we usually administer, plus fluconazole (50 mg/day) starting from the 6th irradiation session throughout the treatment; 39 patients in group B received the same baseline treatment, but were given the drug only when mycotic infections appeared. The clinical characteristics, treated sites, treatment doses and volumes were similar in the two groups of patients. Fluconazole was well tolerated and no early or late toxicity was observed. We had 1 mycotic mucositis and 14 non-scheduled treatment discontinuations in group A, vs. 19 and 30, respectively, in group B. Radiation therapy lasted 52.3 days (mean) in group A and 55.6 days (mean) in group B; the differences were statistically significant. In our experience, fluconazole, used prophylactically from the 6th radiotherapy session on, reduced the number of mycotic infections and improved radiotherapy schedule in our head and neck cancer patients.

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.

The authors report on the results of the immune monitoring of a study population of 31 patients with lung cancer who were treated with radiotherapy. A synthetic thymic pentapeptide, thymopentin, was employed whose effect was evaluated on the immunological parameters analyzed. After radiotherapy, a considerable and homogeneous decrement was observed in several lymphocytic subsets (less sensible in activated T-cells), together with a progressive decrement in the helper/suppressor ratio, in the long run. Monocytes and null cells showed more radioresistance. Thymopentin had no influence on the tested immunological parameters up to 6 months after radiotherapy; later on, a slightly more balanced helper/suppressor ratio could be noticed in the surviving patients who had been treated with thymopentin.

Twenty-four lectures were reviewed of the XXXIII SIRMN National Congress (Rome, October 1988) on the conservative radiosurgical treatment of breast cancer. A whole of 3462 cases were divided into 2 groups: group A--2824 patients who underwent targeted radiotherapy after conservative surgery (mostly quadrantectomy)--and group B--638 patients where, in case of N+ and internal quadrant tumors, irradiation was extended to lymph nodes. No significant differences were demonstrated between group A and group B as far as loco-regional relapses were concerned. Thus, no significant advantage seems to be yielded by lymph node irradiation in the early treatment of breast cancer.

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.
