RESUMO
The use of immediate postoperative and salvage radiotherapy in high-risk patients after radical prostatectomy for prostate cancer remains controversial. Immediate postoperative radiotherapy improves biochemical and clinical progression-free survival in randomised trials. Metastasis-free survival and overall survival were seen to be improved in a recently updated randomised trial. On the basis of retrospective data only, salvage radiotherapy is effective against biochemical relapse after prostatectomy. The adjunction of androgen deprivation therapy to immediate postoperative or salvage radiotherapy is only supported by retrospective data. The results of the ongoing, prospective, randomized trials will hopefully enable accurate comparison of immediate postoperative radiotherapy with salvage radiotherapy and assessment of the value of androgen deprivation therapy.

PURPOSE: Analysis of the feasibility and results of adjuvant chemotherapy followed by conformal chemoradiotherapy after surgery for gastric carcinoma. PATIENTS AND METHODS: Twenty-six patients (R0 or R1) were treated postoperatively by three cycles of 5-fluorouracil (5-FU) and cisplatin, followed by a concomitant association of LV5FU2 chemotherapy with a conformal radiotherapy of 45 Gy. RESULTS: The tumor was classified pT3-T4 in 77% of the patients and 92.5% had a nodal involvement (pN1: 54%; pN2: 31%). FEASIBILITY: (1) Adjuvant chemotherapy: nausea/vomiting grade II/III: 12 patients (48%); neutropenia grade III/IV: two patients; completed in all patients, except one. (2) Chemoradiotherapy: nausea/vomiting grade II/III: 10 patients; diarrhea grade II/3: two patients; oesophagitis grade II/III: two patients; myocardial infarction/pulmonary embolism: two patients. All patients except one received the planned dose of 45Gy. Radiotherapy was interrupted in six cases, with a median duration of 14 days. Survival: with a median follow-up of 30 months, 65% of the patients were alive without disease; median survival was 32 months. CONCLUSION: This postoperative schedule was judged feasible. It allowed the deliverance of a more intensified chemotherapy than the classical schedule. Its clinical benefit must be evaluated in a phase III trial.

PURPOSE: Evaluate the clinical utility of procalcitonin (PCT) and C-reactive protein (CRP) as diagnostic of paraneoplastic fever. METHOD: A prospective analysis of serum levels of PCT and CRP has been conducted on 68 consecutive febrile patients with solid tumour and no neutropenia. The samples were collected at hospital admission. RESULTS: Out of 68 patients, 57 had head and neck cancer. Forty-three patients had signs of infection and 19 had paraneoplastic fever. CRP was not significantly different between the two groups (infected patients: median: 134 mg/L, extremes: 20-569; paraneoplastic fever patients: median: 154 mg/L, extremes: 26-267; P = 0.75 with Mann-Whitney test). On the other hand, PCT was significantly higher in case of infection (median: 0.44 ng/mL, extremes: 0.09-57.4) than in the case of paraneoplastic fever (median: 0.26 ng/mL, extremes: 0.05-1.17; P = 0.01 with Mann-Whitney test). CONCLUSION: In our study, no paraneoplastic fever patient had PCT level equal or above 2 ng/mL (negative predictive value of 100%).
