Evaluation of the prognostic meaning of C-reactive protein (CRP) in children and adolescents with classical Hodgkin's lymphoma (HL).

BACKGROUND: In adult cancer patients the negative predictive value of elevated CRP levels has been described for several malignancies. Only few studies have analyzed the prognostic role of CRP in children and adolescents with classical HL. In these studies elevated CRP levels correlate with the presence of classical risk factors and adverse outcome. PATIENTS AND METHODS: The prognostic role of CRP for patients with classical HL admitted to the GPOH-HD-2002 study was analyzed retrospectively. RESULTS: CRP levels were documented for 369 of 573 patients. Significant (p<0.05) increased median CRP levels were found in the presence of B-Symptoms (25.7 vs. 5.1 mg/l), extranodal involvement (21.5 vs. 7.5 mg/l), elevated erythrocyte sedimentation rate (ESR, 13.0 vs. 1.0 mg/l) and stage III/IV disease (15.5 vs. 5.3 mg/l). 83.9% of patients with elevated and 45.8% of patients with normal CRP had an ESR >30 mm/h. CONCLUSION: Elevated CRP levels were associated with classical risk factors of HL. CRP and ESR may reflect different biological processes. CRP was prognostic within early stage TG-1 patients treated with reduced treatment, but not within advanced stage TG-2+3.

Primary and secondary breast lymphoma: prevalence, clinical signs and radiological features.

OBJECTIVES: The purpose of this study was to determine the prevalence, clinical signs and radiological features of breast lymphoma. METHODS: This is a retrospective review of 36 patients with breast lymphoma (22 primary and 14 secondary). 35 patients were female and 1 was male; their median age was 65 years (range 24-88 years). In all patients, the diagnosis was confirmed histopathologically. RESULTS: The prevalence of breast lymphoma was 1.6% of all identified cases with non-Hodgkin lymphoma and 0.5% of cases with breast cancer. B-cell lymphoma was found in 94% and T-cell lymphoma in 6%. 96 lesions were identified (2.7 per patient). The mean size was 15.8 ± 8.3 mm. The number of intramammary lesions was higher in secondary than in primary lymphoma. The size of the identified intramammary lesions was larger in primary than in secondary lymphoma. Clinically, 86% of the patients presented with solitary or multiple breast lumps. In 14%, breast involvement was diagnosed incidentally during staging examinations. CONCLUSION: On mammography, intramammary masses were the most commonly seen (27 patients, 82%). Architectural distortion occurred in three patients (9%). In three patients (9%), no abnormalities were found on mammography. On ultrasound, the identified lesions were homogeneously hypoechoic or heterogeneously mixed hypo- to hyperechoic. On MRI, the morphology of the lesions was variable. After intravenous administration of contrast medium, a marked inhomogeneous contrast enhancement was seen in most cases. On CT, most lesions presented as circumscribed round or oval masses with moderate or high enhancement.
