BACKGROUND: Recent research suggests that patients' appraisal of somatic symptoms is more closely related to emotional variables (particularly negative affect) than to their actual health as determined by external criteria. METHODS: Sixty surgical cancer patients who at the time of a routine follow-up examination filled out the European Organization for Research and Treatment of Cancer (EORTC) quality of life questionnaire-C30, which included a positive/negative affect scale and a scale tapping into experienced social stigma. Patients' health status was determined in two ways: the examining physician gave a global judgement on a standardized scale at the end of the examination, and an additional two external physicians later rated the patients based on the findings listed in the medical record. RESULTS: Patients' reports of somatic symptoms were strongly correlated with two measures of negative affect (r = 0.75 and r = 0.65, respectively) and with experienced social stigma (r = 0.51). In contrast, the correlations between reported symptoms and the examining or external physicians' ratings were considerably weaker (r = 0.31 and r = 0.19). According to a multiple linear regression with 6 predictors, negative affect was the best single predictor of symptom reporting (beta = 0.68; P < 0.001) and global quality of life (beta = 0.48; P < 0.001). Factor analysis yielded a dimension of somatopsychosocial distress that accounted for 44.1% of the variance and is comprised of reported symptoms (factor loading = 0.86), negative affect (0.90 and 0.82), experienced social stigma (0.74), and global quality of life (0.70). Physicians' ratings and positive affect constituted two additional separate factors. CONCLUSIONS: Cancer patients' reporting of somatic symptoms by means of a standardized quality of life questionnaire is closely related to emotional and social distress and is not equivalent to health status as determined from a clinical perspective. Researchers and practitioners have to be aware of this fact when interpreting quality of life data. Furthermore, negative affect deserves attention as an important signal for intervention in tumor follow-up programs.
During a 2 year period (1992-1993), 149 patients with advanced abdominal cancer underwent total abdominal ischemic perfusion (TAP) and stop-flow infusion (SFI) 159 times in an attempt to achieve palliation. These procedures and aortic stop-flow infusion require insertion of balloon catheters into the abdominal aorta and inferior vena cava by a transfemoral approach. Flow is arrested for 15 minutes, during which time chemotherapeutic agents are infused into the aorta, distal to the balloon occlusion. Femoral access is by a surgical incision. The passage of the catheters is guided by fluoroscopy. Some tumor response was observed in 35% of the patients. Ten patients had major vascular complications; two iliac artery aneurysms were lacerated and required emergency repair. There were two femoral artery false aneurysms that required surgical correction, one early and one late. Aortic dissection was detected in four patients, but these did not require surgical intervention. Two patients had thrombosis distal to the occluded vessel, both required surgical intervention. To reduce the incidence of these vascular complications we recommend: (1) a clinical and vascular laboratory evaluation before the procedure, and (2) angiography of normal flow in patients with underlying vascular disease.
