  • Early prediction of response to first-line chemotherapy by sequential [18F]-2-fluoro-2-deoxy-D-glucose positron emission tomography in patients with advanced colorectal cancer

    • BACKGROUND: To evaluate [(18)F]-2-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET), for early evaluation of response to palliative chemotherapy and for prediction of long-term outcome, in patients with metastatic colorectal cancer (mCRC). PATIENTS AND METHODS: In a randomized trial, patients with mCRC received irinotecan-based combination chemotherapy. FDG-PET was carried out before treatment and after two cycles in 51 patients at two centers. Visual changes in tumor FDG uptake and changes measured semi-automatically, as standard uptake values (SUVs), were compared with radiological response after four and eight cycles. RESULTS: The mean baseline SUV for all tumor lesions per patient was higher in nonresponders than in responders (mean 7.4 versus 5.6, P = 0.02). There was a strong correlation between metabolic response (changes in SUV) and objective response (r = 0.57, P = 0.00001), with a sensitivity of 77% and a specificity of 76%. There was no significant correlation between metabolic response and time to progression (P = 0.5) or overall survival (P = 0.1). CONCLUSIONS: Although metabolic response assessed by FDG-PET reflects radiological tumor volume changes, the sensitivity and specificity are too low to support the routine use of PET in mCRC. Furthermore, PET failed to reflect long-term outcome and can, thus, not be used as surrogate end point for hard endpoint benefit.

  • Cancer risk in hospitalized sarcoidosis patients: a follow-up study in Sweden
  • 2009
  • Ingår i: Annals of Oncology. - : Elsevier BV. - 1569-8041 .- 0923-7534. ; 20:6, s. 1121-1126
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Sarcoidosis patients show dysregulated immune function, which may be related to subsequent cancer. We examined here the overall and specific cancer risks among Swedish subjects who had been hospitalized for sarcoidosis. Methods: A sarcoidosis research database was created by identifying hospitalized sarcoidosis patients from the Swedish Hospital Discharge Register and by linking them with the Cancer Registry. Standardized incidence ratios (SIRs) were calculated for cancers in sarcoidosis patients compared with subjects without sarcoidosis. Results: A total of 10 037 patients were hospitalized for sarcoidosis during years 1964-2004. Among them 1045 patients developed subsequent cancer, giving an overall SIR of 1.40 and 1.18 for cancer diagnosed later than 1 year of follow-up. A significant excess was noted for skin (squamous cell), kidney and nonthyroid endocrine tumors and additionally for non-Hodgkin's lymphoma and leukemia. Patients with multiple hospitalizations showed high risks. Conclusions: A 40% overall excess incidence of cancer was noted among sarcoidosis patients, but the increase was confined mainly to the first year after hospitalization. However, the increased risks of skin cancer and non-Hodgkin's lymphoma and leukemia, especially for those with multiple hospitalizations or hospitalized at old age, call for clinical attention.
