[Q]: Is weight-training exercise intervention harmful to women with or at risk of breast cancer-related lymphoedema?', 'Systematic review with meta-analysis of randomised trials.', 'Women with or at risk of breast cancer-related lymphoedema.', 'Progressive weight-training exercise.', 'The primary outcomes were severity (volume difference) and incidence of arm lymphoedema. Secondary outcomes included muscle strength of the upper and lower limbs, quality of life and body mass index.', 'Eleven studies from eight trials involving 1091 women were included. Weight-training exercise of low to moderate intensity with relatively slow progression significantly improved the upper limb strength (SMD 0.93, 95% CI 0.73 to 1.12) and lower limb strength (SMD 0.75, 95% CI 0.47 to 1.04) without increasing the arm volume (SMD -0.09, 95% CI -0.23 to 0.05) or incidence of breast cancer-related lymphoedema (RR 0.77, 95% CI 0.52 to 1.15). No significant effects were noted for body mass index (SMD -0.10, 95% -0.31 to 0.11). Some aspects of quality of life may improve with weight training. PARTICIPANTS in all trials used pressure garments and received supervision; no trials used high-intensity weight training.

[Q]: To determine the influence of age on survival of patients undergoing resection for lung cancer.', 'Retrospective.', 'South-western part of the Netherlands.', 'Follow-up information was gathered on patients who had undergone resection for stage I non-small cell lung cancer from 1984 through 1990 and had been registered by the Rotterdam Cancer Registry. Operative mortality, 2-year and 5-year survival in the age groups 20-59, 60-69 and 70 years and older were compared.', 'Of the 630 patients (median age of 66 years) one-third was 70 years or older. Operative mortality was mainly determined by the type of operation: 6% after pneumonectomy versus 1% after lesser resections. Five-year survival declined with age from 65% to 48% and 43% (p < 0.01). After adjustment for non-related causes of death this difference decreased: 68%, 55%, 61% (p = 0.15). The main prognostic factor was tumour size.
