RESUMEN

UNLABELLED: Our randomized controlled trial in prematurely menopausal breast cancer survivors showed that impact + resistance training prevented increases in percentage of body fat compared with controls and also improved BMD at the hip and prevented BMD loss at the spine among exercise-trained women who were menopausal for >1 year. INTRODUCTION: Cancer treatment-related menopause worsens bone health and body composition in breast cancer survivors (BCS). We investigated whether impact + resistance training could improve bone mineral density (BMD), reduce bone turnover, build muscle, and decrease fat mass in BCS with premature menopause. METHODS: We conducted a randomized controlled trial in 71 BCS (mean age, 46.5 years) within 5 years of treatment-related menopause. Women were randomly assigned to one of two groups: (1) impact + resistance training (prevent osteoporosis with impact + resistance (POWIR)) or (2) exercise placebo (FLEX) 3×/week for 1 year. Outcomes were hip and spine BMD (in grams per square centimeter) and body composition (percent body fat (%BF) and lean and fat mass (in kilograms)) by DXA and bone turnover markers (serum osteocalcin (in nanograms per milliliter) and urinary deoxypryrodinoline (in nanomoles per milliliter). RESULTS: There were no significant group × time interactions for bone outcomes when using an intent-to-treat approach on the full sample. In analyses restricted to BCS who were menopausal for ≥1 year, POWIR increased BMD at the hip and slowed BMD loss at the spine compared with FLEX (femoral neck-POWIR, 0.004 ± 0.093 g/cm(2) vs. FLEX, -0.010 ± 0.089 g/cm(2); p < 0.01; spine-POWIR, -0.003 ± 0.114 g/cm(2) vs. FLEX, -0.020 ± 0.110 g/cm(2); p = 0.03). POWIR prevented increases in %BF (POWIR, 0.01 % vs. FLEX, 1.3 %; p < 0.04). Women with attendance to POWIR at ≥64 % had better improvements in %BF than women attending less often (p < 0.03). CONCLUSION: Impact + resistance training may effectively combat bone loss and worsening body composition from premature menopause in BCS.

RESUMEN

51Cr-bleomycin was used for the scintigraphic diagnosis of primary and secondary tumours of the thorax. The study was based on observations in 104 patients. The scintigraphy was performed using a gamma camera coupled to an on-line computer. Active lesions were scored using a semiquantitative scale of scores 0 to 5. Images were subdivided into 222 regions considered. In 72 of these, the presence of disease was diagnosed (64 malignant, 8 non-malignant) and 150 regions were classified as free from disease. At the decision threshold of score 2, over-all sensitivity and specificity of the scintigraphic detection of malignant tumours amounted to 97 and 79%, respectively. Inflammatory changes displayed some detectable accumulation of 51Cr-bleomycin but scores attributed to these lesions did not exceed the value of 2.
