- Background: Our aims were to evaluate the response to salvage treatment in relation to initial treatment and to evaluate prognostic factors at the time of relapse in an unselected population of relapsing patients with Hodgkin's lymphoma (HL). Patients and methods: In total, 124 patients younger than 60 yr of age with initial diagnosis of HL in Sweden relapsed between 1985 and 1995. Results: Fifty-eight patients relapsed after initial treatment with radiotherapy (RT) only, 62 after combination chemotherapy (CT), of whom 30 had received additional involved-field RT, and four after a short course of CT followed by extended-field RT. For 37 patients among the 58 relapsers after initial RT treated according to the recommendations of the National guidelines, the 5-yr Hodgkin-specific survival (HLS) was 85%, overall survival (OS) 73% and event-free survival (EFS) 62%, which is not inferior to survival in patients with primarily advanced stages. It was poorer in the 21 patients who initially had received RT only, even though they had been recommended for more extensive treatment. For patients initially treated with a full course (6-8 cycles) of CT the 5-yr HLS was 60%, OS 58% and EFS 22%. Bulky disease and age at diagnosis strongly affected survival in a multivariate analysis. Conclusions: Patients initially treated with RT who relapse have a favourable outcome, provided they have been treated according to the recommendations of the guidelines at the time of diagnosis. Initially bulky disease and, as a consequence, additional RT as part of the initial treatment negatively affect survival at relapse in patients initially treated with a full course of CT.

- A multiple-primer DNA sequencing approach suitable for genotyping, detection and identification of microorganisms and viruses has been developed. In this new method two or m ore sequencing primers, combined in a pool, are added to a DNA sample of interest. The oligonucleotide that hybridizes to the DNA sample will function as a primer during the subsequent DNA sequencing procedure. This strategy is suited for selective detection and genotyping of relevant microorganisms and samples harboring different DNA targets such as,multiple variant/infected samples as well as unspecific amplification products. This method is used here in a model system for detection and typing of high-risk oncogenic human papilloma viruses (HPVs) in samples containing multiple infections/variants or unspecific amplification products. Type-specific sequencing primers were designed for four of the most oncogenic (high-risk) HPV types (HPV-16, HPV-18, HPV-33, and HPV-45). The primers were combined and added to a sample containing a mixture of one high-risk (16, 18, 33, or 45) and one or two low-risk types. The DNA samples were sequenced by the Pyrosequencing(TM) technology and the Sanger dideoxy sequencing method. Correct genotyping was achieved in all tested combinations. This multiple-sequencing primer approach also improved the sequence data quality for samples containing unspecific amplification products. The new strategy is highly suitable for diagnostic typing of relevant species/genotypes of microorganisms.
