- BACKGROUND: Despite improved treatment results achieved in Hodgkin's disease (HD), only about 70% of patients with advanced stages are cured. The primary aim of this study was to evaluate the outcome of advanced stages (IIB-IVB) of HD in younger patients in an unselected population-based group of patients. The patients were recommended individualized treatment with respect to number of chemotherapy (CT) courses and post-CT radiotherapy (RT) based on pretreatment characteristics and tumour response. Secondly, we investigated if variables of prognostic importance could be detected.PATIENTS AND METHODS: Between 1985-92, 307 patients between 17-59 yr of age (median 36) were diagnosed with HD in stages IIB-IVB in 5/6 health care regions in Sweden. Median follow-up time was 7.8 yr (1.3-13). Retrospectively, laboratory parameters were collected.RESULTS: In total, 267 (87%) patients had a complete response (CR). The overall and disease-free 10-yr survivals in the whole cohort were 76% and 67%, respectively. There was no difference in survival between the groups of patients who received 6 or 8 cycles of CT. Survival was not higher for patients in CR after CT when RT was added. For those in PR after CT, additional RT raised the frequencies of CR. A selected group of pathologically staged patients was successfully treated with a short course (2 cycles) of CT + RT. In univariate analyses survival was affected by age, stage IVB, bone-marrow involvement, B-symptoms, S-LDH, S-Alb and reaching CR or not after 2, 4 and 6 cycles of CT. In a multivariate analysis, age and reaching CR after 6 cycles of CT remained statistically significant.CONCLUSIONS: The lack of difference in survival between the groups of patients who received 6 versus 8 cycles of CT indicates a successful selection of patients for the shorter treatment. Reaching a rapid CR significantly affected outcome. Whether some patients need less CT than the generally recommended 8 courses can properly only be evaluated in a randomised study. Additional RT may play a role in successful outcome, particularly if residual tumours are present, but its precise role can also only be defined in prospectively randomised studies. Reaching CR after CT was the most important variable affecting survival besides age.

- The current treatment recommendation for T2-3N0M0 glottic squamous cell carcinoma (SCC) in the Nordic countries comprises of radiotherapy (RT) and chemoradiotherapy (CRT). Tumor radiosensitivity varies and another option is primary surgical treatment, which underlines the need for predictive markers in this patient population. The aim of the present study was to investigate the relation of the proteins WRAP53 beta, survivin and p16INK4a to RT/CRT response and ultimate outcome of patients with T2-T3N0 glottic SCC. Protein expression was determined using immunohistochemistry on tumors from 149 patients consecutively treated with RT or CRT at Helsinki University Hospital, Karolinska University Hospital, and Linkping University Hospital during 1999-2010. Our results demonstrate a significantly better 5-year relapse-free survival, disease-free survival (DFS), disease-specific survival and overall survival of patients with T3N0 tumors treated with CRT compared with RT alone. Patients with tumors showing a cytoplasmic staining of WRAP53 beta revealed significantly worse DFS compared with those with nuclear staining. For survivin, we observed a trend towards better 5-year DFS in patients with strong nuclear survivin expression compared with those with weak nuclear survivin expression (p=0.091). Eleven (7%) tumors showed p16 positivity, with predilection to younger patients, and this age group of patients with p16-positive SCC had a significantly better DFS compared with patients with p16-negative SCC. Taken together, our results highlight WRAP53 beta as a potential biomarker for predicting RT/CRT response in T2-T3N0 glottic SCC. p16 may identify a small but distinct group of glottic SCC with favorable outcome. Furthermore, for T3N0 patients better outcome was observed following CRT compared to RT alone.
