- Objectives To evaluate the risk of haematological malignancies in patients with psoriatic arthritis (PsA) overall, and in relation to treatment with tumour necrosis factor inhibitors (TNFi).Methods We identified that patients with PsA starting a first TNFi from the clinical rheumatology registers (CRR) in the five Nordic countries (n=10 621) and biologics-naive PsA patients from (1) the CRR (n=18 705) and (2) the national patient registers (NPR, n=27 286, Sweden and Denmark) from 2006 through 2019. For Sweden and Denmark, general population comparators were matched 5:1 to PsA patients on birth year, year at start of follow-up and sex. By linkage to the national cancer registers in all countries, we collected information on haematological malignancies overall, and categorised into lymphoid or myeloid types. We estimated incidence rate ratios (IRRs) with 95% CIs using modified Poisson regression for TNFi-treated versus biologics-naive PsA patients and versus the general population adjusted for age, sex, calendar period and country.Results During 59 827 person-years, 40 haematological malignancies occurred among TNFi-treated patients with PsA resulting in a pooled IRR of 0.96 (0.68-1.35) versus biologics-naive PsA from CRR and an IRR of 0.84 (0.64-1.10) versus biologics-naive PsA from NPR. The IRR of haematological malignancies in PsA overall versus general population comparators was 1.35 (1.17-1.55). The estimates were largely similar for lymphoid and myeloid malignancies.Conclusions Treatment with TNFi in patients with PsA was not associated with an increased incidence of haematological malignancies. Conversely, a moderately increased underlying risk was seen in patients with PsA compared with the general population.

- Objectives: This study aims to characterize the epidemiology of immunocompetent Primary central nervous system lymphoma (PCNSL) diagnosed 2000-2013 in Sweden.Methods: Cases were identified in the population-based Swedish Lymphoma Register. Incidence per 100000 person-years and 95% confidence intervals (CI) were calculated, and PCNSL-specific survival was estimated using relative survival. Tests for temporal trends were performed using Poisson regression. Population incidence of all brain tumors was retrieved for comparison.Results: With 359 identified PCNSL cases (median age 66years), overall incidence was 0.26 (95% CI: 0.24-0.29) and the average annual increase 4% (P=.002). The increasing trend was primarily observed among elderly individuals (70+years). Similarly, an increase in incidence of all brain tumors was noted only among the elderly. There was no significant improvement in relative survival across the study period although, among fit patients (with Eastern Cooperative Oncology Group, EGOC 0), survival plateaued 6years after diagnosis.Conclusion: The increasing PCNSL incidence in the elderly was consistent with an increasing incidence of brain tumors of any type and may in part be attributable to improved diagnostics and reporting in this group. New treatment options have not yet translated into general survival improvements in a population-based setting, although the presence of long-term survivors among fit patients is encouraging.

- Radiotherapy or radical hysterectomy with salpingo-oophorectomy (SOE) as treatment for uterine cervical cancer causes estrogen deprivation in premenopausal women. The effects on androgen production have rarely been examined but could be relevant for survivors of cervical cancer because insufficiency has been associated with low sexual function.

- Background High-resolution genomic microarrays enable simultaneous detection of copy-number aberrations such as the known recurrent aberrations in chronic lymphocytic leukemia [del(11q), del(13q), del(17p) and trisomy 12], and copy-number neutral loss of heterozygosity. Moreover, comparison of genomic profiles from sequential patients' samples allows detection of clonal evolution. Design and Methods We screened samples from 369 patients with newly diagnosed chronic lymphocytic leukemia from a population-based cohort using 250K single nucleotide polymorphism-arrays. Clonal evolution was evaluated in 59 follow-up samples obtained after 5-9 years. Results At diagnosis, copy-number aberrations were identified in 90% of patients; 70% carried known recurrent alterations, including del(13q) (55%), trisomy 12 (10.5%), del(11q) (10%), and del(17p) (4%). Additional recurrent aberrations were detected on chromosomes 2 (1.9%), 4 (1.4%), 8 (1.6%) and 14 (1.6%). Thirteen patients (3.5%) displayed recurrent copy-number neutral loss of heterozygosity on 13q, of whom 11 had concurrent homozygous del(13q). Genomic complexity and large 13q deletions correlated with inferior outcome, while the former was linked to poor-prognostic aberrations. In the follow-up study, clonal evolution developed in 8/24 (33%) patients with unmutated IGHV, and in 4/25 (16%) IGHV-mutated and treated patients. In contrast, untreated patients with mutated IGHV (n=10) did not acquire additional aberrations. The most common secondary event, del(13q), was detected in 6/12 (50%) of all patients with acquired alterations. Interestingly, aberrations on, for example, chromosome 6q, 8p, 9p and 10q developed exclusively in patients with unmutated IGHV. Conclusions Whole-genome screening revealed a high frequency of genomic aberrations in newly diagnosed chronic lymphocytic leukemia. Clonal evolution was associated with other markers of aggressive disease and commonly included the known recurrent aberrations.

- In this longitudinal study we prospectively enrolled 32 premenopausal women (ages 23-44years) with stage I-III uterine cervical cancer undergoing surgery and/or chemoradiation. Serum levels of anti-Müllerian hormone, follicle-stimulating hormone and estradiol were examined at baseline and 1year after treatment. As expected, serum anti-Müllerian hormone was undetectable after salpingo-oophorectomy or chemoradiation. After radical hysterectomy and pelvic lymphadenectomy with ovarian preservation serum anti-Müllerian hormone declined from a mean value of 2.0±1.4μg/L to 1.1±0.8μg/L (p=0.01), representing a 45% reduction, whereas there was no significant change in serum levels of follicle-stimulating hormone and estradiol. This implies that ovarian function may be affected not only by castrating treatment but also by radical hysterectomy with ovarian preservation. The risk of premature menopause and the potential need of hormone replacement therapy among these women may be overlooked since they no longer menstruate.

- OBJECTIVE: Patients with rheumatoid arthritis (RA), in particular those with the most severe disease, are at increased risk of malignant lymphoma. Whether this increase is entirely consequential to the RA disease and/or its treatment or reflective of shared susceptibility to the two diseases remains unclear. To resolve this, we assessed whether patients with RA are at increased risk of lymphoma or of other cancers, already before diagnosis of RA, and if the relative risk increases with time since RA diagnosis.METHODS: 6,745 patients with incident RA (ACR criteria, symptom duration < 1 year) registered in the Swedish Early RA register from 1997 through 2006 were identified. For each patient, five general population controls were randomly matched by gender, age, marital status and residence (n=33,657). All individuals were linked to the nationwide Swedish Cancer Register 1958-2006. Relative risks (RR) of lymphoma and cancer overall before and after the diagnosis of RA were estimated using conditional logistic and Cox regression, respectively.RESULTS: Before diagnosis of RA, no increased risk of lymphoma (RR= 0.67, 95% CI 0.37-1.23) or other cancers (RR= 0.78, 95% CI 0.70-0.88) was observed. During the first ten years following diagnosis of RA, the overall RR of lymphoma was 1.75 (95 % CI 1.04-2.96).CONCLUSION: Overall, a history of cancer, lymphoma included, does not increase the risk of subsequent RA development. Shared susceptibility for RA and lymphoma may thus be of limited importance. By contrast increased lymphoma risks were observed already within the first decade following RA diagnosis.

- OBJECTIVES: To estimate the association between biological DMARDs (bDMARDs; overall and by drug) as used in RA and the risk of malignant lymphomas including subtypes.METHODS: By linking nationwide Swedish registers we identified cohorts of patients with RA initiating treatment with a bDMARD (n = 16 392), bDMARD-naïve (n = 55 253), an age- and sex-matched general population comparator cohort (n = 229 047), and all incident lymphomas 2001-16. We used Cox regression to calculate hazard ratios (HRs) of lymphoma taking calendar period and other factors into account.RESULTS: There were 82 lymphomas among the bDMARD-treated patients with RA, crude incidence rate 76/100 000 person-years, and 310 lymphomas among the bDMARD-naïve patients with RA, crude incidence rate 90/100 000 person-years. This resulted in an adjusted HR (aHR) associated with bDMARD treatment (vs not) of 1.08 (95% CI: 0.83, 1.41). The corresponding aHR for bDMARD-treated and bDMARD-naïve vs the general population was 1.65 (95% CI: 1.31, 2.08) and 1.56 (95% CI: 1.37, 1.78) respectively. Restricting follow-up period to after 2006, the aHR of lymphoma for patients with RA starting a first bDMARD vs bDMARD-naïve was 0.69 (95% CI: 0.47, 1.00), and for bDMARD treated vs patients with RA switching from one conventional synthetic DMARDs to another, aHR was 0.46 (95% CI: 0.28, 0.73). There were no signals of different risks with any particular TNF inhibitor (TNFi) agent. We found no different lymphoma subtype pattern following bDMARD therapy.CONCLUSION: Treatment with bDMARDs, including both TNFi and non-TNFi bDMARDs, does not further increase the lymphoma risk in RA; instead, bDMARD treatment may actually reduce the excess lymphoma risk in RA.
