To quantify the risk of second primary cancers among patients with cutaneous malignant melanoma, we studied 20,354 patients in the Swedish Cancer Register during 1958-88. A second primary cancer was reported in 1605 patients, compared with an expected number of 1109.5 [standardised incidence ratio (SIR) = 1.45, 95% confidence interval (CI) = 1.38-1.52]. The(More)
In a retrospective study, O(6)-methylguanine-DNA-methyltransferase (MGMT) expression was analysed by immunohistochemistry using monoclonal human anti-MGMT antibody in melanoma metastases in patients receiving dacarbazine (DTIC) as single-drug therapy or as part of combination chemotherapy with DTIC-vindesine or DTIC-vindesine-cisplatin. The correlation of(More)
We analysed 26 metastases from 25 patients with sporadic cutaneous malignant melanoma for alterations in the CDKN2 gene by a combined polymerase chain reaction/single-strand conformation polymorphism (PCR/SSCP)/nucleotide sequencing approach. Eleven alterations (one in exon 1, five in exon 2 and five in the 3' non-coding sequence of the exon 3 region) were(More)
A common characteristic of cancer cells is unrestrained cell division. This may be caused by mutational changes in genes coding for components of cell cycle-controlling networks. Alterations in genes involved in G1 checkpoint control have been registered in many human tumours, and investigations from several laboratories show that such alterations, taken(More)
Tumour samples obtained from one primary melanoma and several lymph node and skin metastases were analysed for O6-methylguanine-DNA methyltransferase (MGMT) activity. While lymph node and skin metastases had similar average MGMT activity, the variance was significantly higher in lymph node metastases. Variability in MGMT activity was frequently observed in(More)
Purpose: Lympboprolifcrativc ocular adnexal lesions represent 1 spectrum of disorders which range from reactive lymphoid hyperplasia to malignant lymphoma and include lewas which ared an mddcrminatc nature morphologrccally and immunophenotypically. Futhmnwe cases have been ckcvmented where progresswn from reactix hyperplasia to frank Ippboma has camed. We(More)
