- The aim of this study was to assess whether the TP53 Arg72Pro polymorphism is associated with an increased risk of non-small cell lung cancer (NSCLC). Additionally, in NSCLC patients, we investigated a potential association between this polymorphism and somatic TP53 gene mutations in tumour cells. The study group included 240 NSCLC patients who underwent curative pulmonary resection. The control group (576 healthy subjects) was matched for sex and cigarette smoking. TP53 Arg72Pro polymorphism was determined by denaturing high-performance liquid chromatography. Tumours from 157 NSCLC patients were analysed for mutation in TP53 exons 5-8 by single strand conformation polymorphism, followed by sequencing of samples with different band pattern. Tumours from the remaining 83 patients were subjected to a direct sequencing of TP53 exons 5-8. The proportion of Pro homo/heterozygotes versus Arg homozygotes was significantly higher in NSCLC patients (54%) than in controls (46%, p = 0.034). The crude odds ratio for NSCLC development in Pro72 allele carriers was 1.39 (95% CI: 1.03-1.88). When adjusted for sex, age and smoking status in the multivariate logistic regression model, odds ratio for NSCLC development was 1.28 (95% CI: 0.91-1.80). Somatic TP53 mutations were found in 62 out of 240 NSCLC patients (26%), more frequently in Pro carriers (31%) than in Arg homozygotes (20%, p = 0.06). These results indicate that the TP53 codon 72 Pro allele may increase the risk of NSCLC. Additionally, the correlation between Pro72 and somatic TP53 mutations suggests that Pro72 allele carriers may be predisposed to tumour development along a p53 associated form of NSCLC, a finding that warrants further investigations.

Human marginal zone B cell development from early T2 progenitors.
- 2021

In: The Journal of experimental medicine. - 1540-9538. ; 218:4
-
Journal article (peer-reviewed)abstract
- B cells emerge from the bone marrow as transitional (TS) B cells that differentiate through T1, T2, and T3 stages to become naive B cells. We have identified a bifurcation of human B cell maturation from the T1 stage forming IgMhi and IgMlo developmental trajectories. IgMhi T2 cells have higher expression of α4β7 integrin and lower expression of IL-4 receptor (IL4R) compared with the IgMlo branch and are selectively recruited into gut-associated lymphoid tissue. IgMhi T2 cells also share transcriptomic features with marginal zone B cells (MZBs). Lineage progression from T1 cells to MZBs via an IgMhi trajectory is identified by pseudotime analysis of scRNA-sequencing data. Reduced frequency of IgMhi gut-homing T2 cells is observed in severe SLE and is associated with reduction of MZBs and their putative IgMhi precursors. The collapse of the gut-associated MZB maturational axis in severe SLE affirms its existence in health.

Novel Benchmark Values for Redo Liver Transplantation Does the Outcome Justify the Effort?
- 2022
-
In: Annals of Surgery. - : Lippincott Williams & Wilkins. - 0003-4932 .- 1528-1140. ; 276:5, s. 860-867

Journal article (peer-reviewed)abstract
- Objective: To define benchmark cutoffs for redo liver transplantation (redo-LT). Background: In the era of organ shortage, redo-LT is frequently discussed in terms of expected poor outcome and wasteful resources. However, there is a lack of benchmark data to reliably evaluate outcomes after redo-LT. Methods: We collected data on redo-LT between January 2010 and December 2018 from 22 high-volume transplant centers. Benchmark cases were defined as recipients with model of end stage liver disease (MELD) score <= 25, absence of portal vein thrombosis, no mechanical ventilation at the time of surgery, receiving a graft from a donor after brain death. Also, high-urgent priority and early redo-LT including those for primary nonfunction (PNF) or hepatic artery thrombosis were excluded. Benchmark cutoffs were derived from the 75th percentile of the medians of all benchmark centers. Results: Of 1110 redo-LT, 373 (34%) cases qualified as benchmark cases. Among these cases, the rate of postoperative complications until discharge was 76%, and increased up to 87% at 1-year, respectively. One-year overall survival rate was excellent with 90%. Benchmark cutoffs included Comprehensive Complication Index CCI (R) at 1-year of <= 72, and in-hospital and 1-year mortality rates of <= 13% and <= 15%, respectively. In contrast, patients who received a redo-LT for PNF showed worse outcomes with some values dramatically outside the redoLT benchmarks. Conclusion: This study shows that redo-LT achieves good outcome when looking at benchmark scenarios. However, this figure changes in high-risk redo-LT, as for example in PNF. This analysis objectifies for the first-time results and efforts for redo-LT and can serve as a basis for discussion about the use of scarce resources.

Continuous versus intermittent tamoxifen versus intermittent/alternated tamoxifen and medroxyprogesterone acetate as first line endocrine treatment in advanced breast cancer: An EORTC phase III study (10863)

Journal article (peer-reviewed)abstract
- Background: Continuous ligand depletion of endocrine responsive tumours may enhance resistance to therapy. Intermittent treatment with tamoxifen (T) was considered to mimic (incomplete) ligand depletion and reintroduction. Furthermore it was postulated that alternating tamoxifen with a non-cross resistant endocrine modality could (further) postpone hormone resistance. Patients and methods: Postmenopausal patients with advanced breast cancer who did not progress after 4 months of first line T therapy were randomised to continue T (40 mg daily) or to 2 monthly intermittent T or intermittent/alternated T and medroxyprogesterone acetate (MPA, 300 mg daily). At progression during break or during MPA, T should be reintroduced. Endpoints of the study were progression free survival (PFS), time to resistance to tamoxifen and overall survival (OS). Results: Of 593 registered patients, 276 were randomised. After 8 years follow-up the median PFS for continuous T, intermittent T and intermittent/alternated T and MPA was 11.0 (8.1-15.2), 8.0 (6.2-12.4) and 10.8 (7.1-16.7) months, respectively (NS). Resistance to tamoxifen was established only in 84%, 70% and 55% of patients in the three treatment arms, respectively The median times from randomisation to resistance to tamoxifen were 12.5 (9.1-21.1), 13.2 (8.8-19.8) and 24.0 (16.9-60.9) months, respectively (p < 0.001), without translation in differences in survival times.

The European Code of Cancer Practice
- 2021
-
In: Journal of Cancer Policy. - : Elsevier BV. - 2213-5383. ; 28
-
Journal article (peer-reviewed)abstract
- There are considerable disparities between the quality of cancer care and clinical outcomes for cancer patients in different European countries, regions, hospitals and communities. These have persisted despite the introduction of many European and National Cancer Plans, an extensive portfolio of clinical guidelines and the existence of evidence based guidelines for the good practice in planning cancer healthcare systems. We describe the European Code of Cancer Practice which is a citizen and patient-centred accessible widely disseminated statement of the core requirements for good clinical cancer practice. The Code sets out 10 key overarching Rights of what a patient should expect from their healthcare system each supported by a plain language explanation. The Rights highlight the importance of equal access to affordable and optimal cancer care, good quality information about an individual patient's disease and treatment and about the quality and outcomes of the cancer service they will use. Specialised multidisciplinary cancer care teams, shared decision-making, research and innovation, a focus on quality of life, the integration of supportive and palliative care within oncology are all emphasised. There is a need for a systematic approach to supporting cancer survivors with a survivorship care plan including their rehabilitation, reintegration into society and return to work where appropriate without discrimination. The Code has been co-produced by a team of cancer patients, patient advocates and cancer professionals to bridge the gap between clinical guidelines, healthcare policies and patients' everyday experience. It is robustly evidence-based and supported by a comprehensive review of the medical literature and evidence for good clinical practice. The Code is strongly endorsed by Europe's professional and patient cancer organisations and the European Commission.
