Cisplatin-based chemotherapy remains the standard treatment for advanced disease and perioperative (neoadjuvant) treatment of BC ( 29). Cisplatin crosslinks DNA in different ways, mainly forming adducts that prevent cell replication and induce cell death. DNA damage can manifest as single-strand breaks (SSBs), double-strand breaks (DSBs) or interstrand-crosslinks ( 30). Cancer cells rely on various mechanisms to repair DNA damage: excision repair, mismatch repair (MMR) or nucleotide excision repair (NER) for SSBs, while non-homologous end joining or homologous recombination (HR) can correct DSBs.

The incidence of paediatric cGvHD shows great variety (ranging from 6 to 65%), with some differences explained by the specific transplant indication (malignant vs. non-malignant), heterogeneity of transplant procedures, and age-related immune reconstitution post transplantation ( 16). In general, paediatric cGvHD tends to be less common and somewhat milder than cGvHD in adults ( 17– 19). Other effects of ECP occur downstream and reflect the disease process that is being treated, the age of the patient and extent of organ damage. Importantly, ECP can induce changes not only in cells in the inoculum which are directly exposed to 8-MOP and UVA but also in cells that are not directly harvested, suggesting that the immunomodulatory effects of ECP propagate beyond directly treated cells. ECP has been shown to induce a switch from a Th1- to Th2-type response with immunomodulatory cytokines in GvHD ( 213, 215). A switch from proinflammatory to anti-inflammatory cytokine production (with a decrease in IFN-γ, TNF-α, and IL-2 secretion and an increase in TGF-β serum levels) as well as increase in T reg numbers has been described ( 214, 216). Additionally, some authors have postulated that ECP impacts on B-lymphocyte homeostasis, with a decrease in CD19 +/CD21 − B-lymphocyte subsets, where others have described the possible expansion of CD8 + memory cells and differentiation of monocytes to immature antigen-presenting cells ( 219, 220). Therefore, the immune modulatory effect of ECP appears to be a complex response to the whole procedure, as depicted in Figure 1.

Our proposed approach is mainly based on the literature and expert opinions and will require confirmation via well-designed studies. In lieu of the evidence-based data needed to inform individualised cGvHD management in paediatric patients, we hope our proposed approach that focuses on patients' individual needs will help clinicians to improve their clinical management of cGvHD. High incidence of infection. Phase 3 REACH3 study: ( 197) significantly greater ORR compared to best available therapy (49.7 vs. 25.6%) at week 24. The most common adverse events were anaemia (29.1%), thrombocytopenia (21.2%), hypertension (15.8%), and pyrexia (15.8%). Moreover, with respect to difficulties in the clinical management of paediatric cGvHD, a plethora of potential infections and drug-induced toxicities make a patient-specific approach of crucial importance. In this regard, the 2020 NIH initiative has emphasised the benefit of applying immunomodulatory agents as opposed to broad immunosuppressive agents ( 225).

In 2013–2014, the Paediatric Diseases Working Party (PDWP) of the EBMT conducted a survey on the use of ECP in paediatric GvHD treatment in routine clinical practice; 52 EBMT centres responded (19%). Results of the analysis revealed that the majority of centres used ECP as an “add on” treatment during various lines of GvHD therapy in patients with a high risk of relapse or infection (81%) or with comorbidities (88%). Of note, 85% of responding centres agreed that, in children, a non-malignant disease and no need of GvL may be an indication for early implementation of ECP within a multimodal GvHD treatment schedule (Lawitschka et al., unpublished results).

Pre-operative MRI in different settings may therefore provide useful information regarding treatment response. Predictive Biomarkers of Response in Cisplatin-Based Chemotherapy After HSCT to cure acute lymphoblastic leukaemia (ALL), paediatric patients are at high risk of developing various long-term sequelae, with cGvHD being one of the major risk factors ( 15). In view of the now longer life expectancy of children post HSCT and the significant cGvHD-related morbidities within a growing body, better understanding and management of paediatric cGvHD is imperative. of Medical Oncology, IRCCS Istituto Romagnolo per lo Studio dei Tumori (IRST) Dino Amadori, Meldola, Italy
