The article exploring the association between chronic obstructive pulmonary disease (COPD), a common pulmonary disorder linked to long-term tobacco smoking, and the risk of cutaneous T-cell lymphoma (CTCL). It study, conducted over a 40-year period in Denmark, suggests that while there is no compelling evidence of increased long-term risk of CTCL overall in COPD patients, there is an association with an elevated risk of mycosis fungoides (MF), the most common subtype of CTCL.

Mycosis fungoides (MF) and parapsoriasis display increased inflammation, which may be associated with increased risk of arterial cardiovascular events. The aim of this Danish nationwide population-based cohort study was to assess the relative risk (RR) of acute myocardial infarction (AMI) or stroke in patients with MF and parapsoriasis. In patients with MF, the RR of AMI or stroke was 1.0 (95% confidence interval (95% CI) 0.7-1.3). In the second half of the study period, the RR was 1.8 (95% CI 1.1-2.9) during the first 5 years of follow-up. In men with parapsoriasis, the RR of AMI or stroke was 1.7 (95% CI 1.1-2.7) within the first 5 years of follow-up, whereas the RR of AMI during the first 5 years of followup was 2.0 (95% CI 1.2-3.4). In conclusion, patients with MF and parapsoriasis have an increased RR of AMI or stroke within the first 5 years of follow-up. [ABSTRACT FROM AUTHOR]

Background. Total skin electron beam therapy (TSEBT) is an effective palliative treatment for cutaneous T-cell lymphoma (CTCL). In the present study we reviewed the clinical response to TSEBT in Danish patients with CTCL. Material and methods. This retrospective study included 35 patients with CTCL treated with TSEBT in Denmark from 2001 to 2008 and followed for a median time of 7.6 months (range 3 days-3.7 years). Twenty five patients were treated with high-dose (30 Gy) and 10 patients in a protocol with low-dose (4 Gy) TSEBT. Results. Patients treated with low-dose therapy had inadequate response to treatment compared to patients treated with high-dose. Consequently the study with low-dose was discontinued and published. In patients treated with high-dose the overall response rate was 100%. Complete response (CR) rate was 68% and CR occurred after a median time of 2.1 months (range 1.8 months-2.0 years). We found no difference in CR rate in patients with T2 (66.7%) and T3 disease (78.6%) (p == 0.64). Following CR 82.4% relapsed at a median time of four months (range 12 days-11.5 months). Relapse-free-survival was similar in patients with T2 and T3 disease (p == 0.77). Progressive disease (PD) was experienced in 28.0% and the median time to PD was 9.0 months (range 4.6-44.3 months). Overall progression-free survival was 95.3%, 72.1% and 64.1% after 0.5-, 1- and 2-years. Effects of initial therapy on TSEBT treatment response and side effects to TSEBT were also analyzed. Conclusion. In conclusion, the present study confirms that high-dose TSEBT is an effective, but generally not a curative therapy in the management of CTCL. High-dose treatment yielded significantly better results than low-dose treatment with 4 Gy. TSEBT offers significant palliation in most patients when other skin-directed or systemic treatments have failed. [ABSTRACT FROM AUTHOR]
