The aim of this study was to estimate the association between objective cardiorespiratory fitness (CRF) and subjective self-reported physical function, taking into account the influence of mental distress. We hypothesized an association between these parameters, since they might be thought to measure parts of the same phenomenon.Approximately 1 month after discontinuation of all primary treatment, 90 cancer patients aged 18-50 years treated with chemotherapy were surveyed. CRF was determined by the Astrand-Ryhming indirect cycle ergometer test, which indicate peak VO2 in mL x kg(-1) x min(-1) (predicted VO2max). Self-reported physical function was assessed by The European Organisation for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30). The relation between VO2max and self-reported physical function was estimated by multiple linear regression. Mental distress (assessed by The Hospital Anxiety and Depression scale), age, gender, body mass index (BMI), time from treatment to physical test and diagnoses were included as potential confounders.There was no association between predicted VO2max and self-reported physical function. Mental distress was negatively associated with self-reported physical function (P0.001), but is not associated with predicted VO2max.The results suggest that predicted VO2max does not reflect self-reported physical function and vice versa in cancer patients after chemotherapy. If information about cardiac and/or pulmonary status is required, direct or indirect measures of VO2max should be used.

This study was conducted to explore treatment and disease-related effects on health-related quality of life (HRQoL) in patients with aggressive lymphoma, to identify predictors for impaired long-term HRQoL, and to analyze the prognostic value of pretreatment HRQoL. Ninety-five patients with aggressive lymphoma, constituting a subset of a randomized multicenter trial comparing CHOP and MACOP-B, entered a HRQoL study, using the EORTC QLQ-C30 questionnaire. Patient scores were compared to scores from an age- and gender-adjusted reference population sample, and evaluation of the prognostic value of pretreatment QoL scores in relation to clinical prognostic factors was performed. Before treatment, patients exhibited lower scores of global QoL, physical, role, and social functions, and more appetite loss, compared to the reference population. Role functioning improved compared to baseline, but remained depressed compared to the reference group more than 8 mo after end of treatment. By then, the patient group displayed no difference in other HRQoL variables compared to that of the reference population. No reliable predictor for impaired long-term HRQoL could be identified. In multivariate analysis, including the factors of the International Prognostic Index, pretreatment global QoL was an independent prognostic marker for overall survival. In conclusion, in this population with aggressive lymphoma and favorable prognostic features, HRQoL was not substantially affected during the first year after diagnosis. Pretreatment global QoL may constitute a significant prognostic factor, meriting further investigation in prospective studies.

Fifty-three examples of developmental "tailgut cysts" in the retrorectal space occurred predominantly in women and caused symptoms of mass effect or pain in 51%. The lesions were usually multicystic and lined by a variety of epithelial types, including ciliated columnar, mucin-secreting columnar, transitional, and squamous epithelium. Inflammation was present in 50%. In one patient a poorly differentiated adenocarcinoma was present. These cysts are most likely derived from remnants of the embryonic tailgut and differ from teratomas. Complete excision of the multilocular and multicystic process prevents recurrent draining sinuses and eliminates the possibility of malignant change.

In a study of 105 gastrointestinal carcinoid tumors, 67% of the rectal carcinoids and 15% of the carcinoids at other gastrointestinal sites were positive, immunohistochemically, for prostatic acid phosphatase activity. These findings are relevant to the differential diagnosis between rectal carcinoids and prostatic carcinoma.

Gastrointestinal teratomas are uncommon, benign neoplasms that occur primarily in children. A retrospective review of five cases (two gastric, one pancreatic, one mesenteric, and one in the lesser omentum) is presented with emphasis on the computed tomographic and ultrasonographic appearances. Principal findings are a well-defined mass with separate cystic and solid components of varying proportions, discrete areas with densities similar to that of fat, or coarse, globular calcifications within the solid component. Recognition of these findings may allow the radiologist to make a correct preoperative diagnosis of teratoma.
