Thirty-three cases of postirradiation sarcoma (PIS) from the files of the Finnish Cancer Registry were analyzed. The most frequent first primary tumors were cancers of the breast (seven cases) and female reproductive organs (13 cases). Five patients had a childhood cancer. The median total radiation dose at the site of the PIS was 3600 cGy (1600 cGy to 11200 cGy). The median interval from start of radiation therapy to detection of PIS was 13.2 years (3.4 to 22.8 years). The PIS was of soft tissue origin in 25 of 33 cases. The most frequent histologic types were osteosarcoma (ten cases, including four extraskeletal tumors), malignant fibrous histiocytoma (ten cases), and fibrosarcoma (six cases). The overall crude 5-year survival rate was 29% (calculated from the start of treatment for PIS), and for patients initially treated with either radical surgery or combined marginal surgery and postoperative irradiation it was 67%. The authors conclude that there is a chance for cure for radically treated patients with postirradiation sarcoma that emphasizes the importance of regular long-term follow-up of cancer patients.
Summary Two hundred and eleven patients with node-positive stage 11 and IlIl breast cancer were treated with eight cycles of adjuvant chemotherapy comprising cyclophosphamide, doxorubicin and oral ftorafur (CAFt), with and without tamoxifen. All patients had undergone radical surgery, and 148 patients were treated with post-operative radiotherapy in two randomized studies. The impact of haematological toxicity of CAFt on distant disease-free (DDFS) and overall survival (OS) was recorded. Dose intensity of all given cycles (Dl), dose intensity of the two initial cycles (Dl2) and total dose (TD) were calculated separately for all chemotherapy drugs and were correlated with DDFS and OS. Patients with a lower leucocyte nadir during the chemotherapy had significantly better DDFS and OS (P = 0.01 and 0.04 respectively). Dose intensity of the two first cycles also correlated significantly with DDFS (P=0.05) in univariate but not in multivariate analysis, while the leucocyte nadir retained its prognostic value. These results indicate that the leucocyte nadir during the adjuvant chemotherapy is a biological marker of chemotherapy efficacy; this presents the possibility of establishing an optimal dose intensity for each patient. The initial dose intensity of adjuvant chemotherapy also seems to be important in assuring the optimal effect of adjuvant chemotherapy.
RISSANEN, PÄ IVI, ANJA FRANSSILA-KALLUNKI, AND AILA RISSANEN. Cardiac parasympathetic activity is increased by weight loss in healthy obese women. Obes Res. 2001;9:637-643. Objective: We studied the effect of weight reduction on cardiac parasympathetic activity (PSA) in obese women. We also studied the relationship between the changes of PSA, resting energy expenditure (REE), and major cardiovascular risk factors. Research Methods and Procedures:Changes of cardiac vagal tone, an index of PSA, REE, and major cardiovascular risk factors, were measured in 52 healthy obese women after a 6-month weight reduction. Ten of the women were remeasured at 12 and 24 months. Cardiac vagal tone was assessed by a vagal tone monitor and REE by indirect calorimeter. Results: Cardiac vagal tone increased significantly (p ϭ 0.046), averaging a 9.5% weight loss in 6 months. The vagal tone increased further with weight loss during the following 6 months, and thereafter, it declined with weight regain. The increase of cardiac vagal tone correlated significantly with decreases of body weight, fat mass, waist circumference, serum insulin, and heart rate. REE adjusted for fat-free mass and age did not change with weight loss and was not related to cardiac vagal tone at any time-point. Discussion: Cardiac PSA activity increases with weight loss in obese women. This increase may not be maintained long-term if body weight is regained. The rise of cardiac PSA is correlated with decreases of body fat mass, abdominal fat, serum insulin, and heart rate. Cardiac PSA is not related to REE.
He has from the outset followed the progress of my work with great interest and given invaluable counsel. I am happy to have this opportunity of expressing my deep gratitude and sincere appreciation to Professor KaUio. I am greatly indebted also to my respected teacher, Professor U. Uotila,
