Adjuvant systemic treatment of resectable breast cancer: eleven years results of a monoinstitutional chemo-hormone-immunotherapy trial

131 patients with resectable, node-positive breast cancer were treated at the National Institute for Cancer Research of Genoa, Italy with a systemic adjuvant regimen based on 14 cycles of chemotherapy, immunostimulation with levamisole, and--for postmenopausal patients--hormone therapy with tamoxifen. The present evaluation is performed eleven years after the admission of the first patient: so far, 75 patients (57.3%) have relapsed and 52 (39.7%) have died. An analysis of prognostic factors for relapse and death shows that the number of positive axillary lymph nodes and the dimension of the primary tumor are significantly associated with survival and relapse-free survival, while age and menopausal status are not.     

Plasma volume in fasted pregnant rats

The effect of a two day fast on maternal plasma volume and plasma protein concentration was explored in pregnant rats. Fasting between days 17 and 19 of gestation prevented the rise in plasma volume observed in ad libitum fed rats. Plasma protein concentration declined between day 17 and day 19 in both fasted and not fasted rats. Placental weight was not reduced by fasting during this stage of gestation. Fetal weight in the fasted group was 91% of the fetal weight of the ad libitum fed group. These results show that acute undernutrition, like longer term food or protein restriction, can prevent adequate plasma volume expansion and slow fetal growth.     

Biliopancreatic Diversion: Clinical Experience

Background: Biliopancreatic diversion (BPD), by ad hoc stomach resection (AHS-BPD) has been accepted as an effective surgical treatment for morbid obesity. Methods: Between 1.1.1992 and 31.7.1996, 59 patients (54 females, five males, mean age 40.3 years, range 23-61 years) underwent AHS-BPD. Mean preoperative body-weight was 121.2 kg (range 94-160), with a mean body mass index of 48.6 (range 35-64). Three of these patients were converted from a previous vertical banded gastroplasty to AHS-BPD (one patient with stomach preservation). After at least 36 months follow-up, seven patients underwent abdominal dermolipectomy (five with associated incisional hernia repair, one with thigh dermolipectomy). Results: Mean post-operative hospital stay was 13 days (range 10-30 days). Follow-up is currently in progress in all patients. Excess body weight-loss was 78% in 33 patients with 24 months follow-up, with excellent long-term weight loss maintenance. Protein deficiency was the main specific complication, encountered in two patients (3.4%). Mortality was one patient (1.7%), due to pulmonary embolus. Conclusions: This clinical experience supports the effectiveness and safety of AHS-BPD, despite some criticism. This procedure appears to be suitable for patients with clinically severe obesity who will poorly tolerate food intake restriction but will accept long-term follow-up. Careful preoperative clinical assessment and selection of patients who will be reliable in long-term follow-up are the keys to success with AHS-BPD, both in terms of weight loss and reduction of specific metabolic complications.     

Oral chemotherapy with idarubicin plus cyclophosphamide in advanced breast cancer.

An oral chemotherapy schedule based on idarubicin and cyclophosphamide was evaluated in 31 advanced breast cancer patients. Out of 27 patients evaluable for response, 1 (3.7%) achieved a complete response and 5 (18.5%) a partial response, with an objective response rate of 22.2% (95% confidence limits 8.6-42.3%). The median time to progression was 7 months (range 3-12). Fourteen patients (51.9%) showed a disease stabilization, and 7 progressed (25.9%). Toxicity was mild. Considering the low response rate, but also the advantages of oral chemotherapy and the mild toxicity observed, oral idarubicin plus cyclophosphamide can be considered as a second-choice regimen in advanced breast cancer.

The impact of chemotherapy on the quality of life of breast cancer patients.

One hundred and thirty-seven breast cancer patients, 102 receiving adjuvant chemotherapy and 35 receiving palliative chemotherapy for metastatic disease underwent a 37-item quality-of-life questionnaire to evaluate the impact of disease and treatment on physical, psychological and social well being. Patient groups were designated as follows--Adj CT: patients undergoing the questionnaire during their adjuvant chemotherapy program; Post Adj CT: patients evaluated 3 to 8 months after termination of adjuvant chemotherapy; Mts CT: patients assessed during palliative chemotherapy for metastatic disease, and Post Mts CT: patients 3 to 8 months after termination of palliative chemotherapy. Physical and social activities were reported as unaltered or normal by 64 to 70% and 52 to 67% of patients, respectively. Psychological status was judged normal by 39 to 45% of patients. No significant differences were observed between the patients groups. In 83 to 90% of cases the patient normally took care of herself. In 62 to 87% of cases time dedicated to recreational activities was reported as unaltered. The majority of patients (84%) judged that their relationship with partner and/or family were good. Severe anxiety was reported in 19 to 28% of patients and severe depression was infrequent (3.9%). Information regarding disease and treatment given by health professionals was considered satisfactory by 80 to 100% of patients.(ABSTRACT TRUNCATED AT 250 WORDS)     

A case of periodic sweating associated with a subarachnoid cyst and multifocal dystonia

Acase of periodic sweating with multifocal dystonia is reported in a 60-year-old woman. At the age of 48 years, she presented with involuntary twisting of the lower face on the right. Six months later she noticed similar movements in the head and right arm. Four years later she began having attacks of generalized sweating over the whole face, anterior region of the trunk and both arms. The attacks occurred hourly each and every day. They lasted for about 10 min and were followed by voluntary urinary voiding. The biochemical and laboratory investigations showed no abnormalities except for the luteinizing hormone and follicle-stimulating hormone values that were below normal. The computerized tomography and magnetic resonance imaging scans revealed a suprasellar cyst. Clonazepam was introduced with partial improvement of the dystonic movements but not of the sweating attacks. The patient refused surgery. Acetazolamide was added and reduced the sweating attacks. We speculate that the periodic sweating may be related to cerebrospinal fluid production and cyst enlargement, hence the ability of acetazoleamide, which reduces cerebrospinal fluid production, to reduce attacks.
