Targeted therapies represent major advancements in the treatment of chronic skin conditions such as psoriasis. While previous studies have shown an increased risk of melanoma and non-melanoma skin cancer (NMSC) in patients receiving TNF-α inhibitors, the risks associated with newer biologics (IL-12/23 inhibitors, IL-23 inhibitors, IL-17 inhibitors) and Janus kinase (JAK) inhibitors remain less known. Using a systematic and meta-analytical approach, we aimed to summarize the currently available literature concerning skin cancer risk in patients treated with targeted therapies. The MEDLINE/PubMed, EMBASE, Web of Science, and Cochrane Library databases were searched to find studies reporting the incidence rates (IR) of melanoma and NMSC in patients with psoriasis and psoriatic arthritis treated with biologics or JAK inhibitors. Nineteen studies were included in the analysis with a total of 13,739 patients. The overall IR of melanoma was 0.08 (95% CI, 0.05–0.15) events per 100 PYs and the overall IR of NMSC was 0.45 (95% CI, 0.33–0.61) events per 100 PYs. The IRs of melanoma were comparable across patients treated with IL-17 inhibitors, IL-23 inhibitors, and JAK inhibitors, while the IRs of NMSC were higher in patients treated with JAK inhibitors than in those treated with biologics. Prospective, long-term cohort studies are required to reliably assess the risks associated with novel targeted therapies.

The purpose of this systematic review and meta-analysis was to compare the risk of non-melanoma skin cancer (NMSC) and melanoma development in renal transplant recipients who receive calcineurin inhibitors to that of patients treated with other immunosuppressive agents, and investigate the possible association between the type of maintenance immunosuppression and the incidence of NSMC and melanoma in this group of patients. The authors searched databases such as PubMed, Scopus, and Web of Science for articles that would help establish the influence of calcineurin inhibitors on skin cancer development. The inclusion criteria for the study consisted of randomized clinical trials, cohort studies, and case-control studies that compared patients who received kidney transplants and were treated with a calcineurin inhibitor (CNI), such as cyclosporine A (CsA) or tacrolimus (Tac), to those who received alternative immunosuppressants and did not receive a CNI. Seven articles were analyzed overall. The results revealed a correlation between CNI treatment in renal transplant recipients and increased total skin cancer risk (OR 1.28; 95% CI: 0.10–16.28; p < 0.01), melanoma risk (OR 1.09; 95% CI: 0.25–4.74; p < 0.01), and NMSC risk (OR 1.16; 95% CI: 0.41–3.26; p < 0.01). In conclusion, the calcineurin inhibitors used after kidney transplantation are associated with a higher risk of skin cancer—both non-melanoma and melanoma—when compared with other immunosuppressive therapies. This finding suggests that careful monitoring for skin lesions in post-transplant patients must be conducted. However, the decision on the kind of immunotherapy used should always be considered on an individual basis for each renal transplant recipient.

Trastuzumab-induced cardiotoxicity (TIC) can lead to early treatment discontinuation. The aim of this study was to evaluate: N-terminal brain natriuretic peptide (NT-proBNP), creatine kinase-MB (CK-MB), myoglobin, and selected biochemical and clinical factors as predictors of TIC. One hundred and thirty patients with HER2-positive BC receiving adjuvant trastuzumab therapy (TT) were enrolled. Measurement of cardiac markers and biochemical tests as well as echocardiography were performed prior to TT initiation and every three months thereafter. Cardiotoxicity leading to treatment interruption occurred in 24 patients (18.5%). While cardiotoxicity caused early treatment discontinuation in 14 patients (10.8%), the TIC resolved in 10 (7.7%) and TT was resumed. The most common complication was a decrease in left ventricular ejection fraction of more than 10% from baseline or below 50% (7.7%). In patients with TIC, there was no increase in the levels of NT-proBNP, myoglobin, and CK-MB. BMI, hypertension, ischemic heart disease, diabetes, age, cancer stage, type of surgery, use of radiotherapy, chemotherapy, and hormone therapy were shown to not have an effect on TIC occurrence. NT-proBNP, myoglobin, and CK-MB are not predictors of TIC. There is an ongoing need to identify biomarkers for TIC.

Introduction. The continuously improving cancer detection at an early stage and improving survival rates have been observed and, therefore, patients are predisposed to detection of multiple primaries. It has been reported that the incidence of multiple primaries in breast cancer patients ranges from of 4% to 17%. Materials and methods. A group of 112 breast cancer patients with synchronous malignancies was presented. They constituted 0.09% of patients (118,952 cases) who were treated for breast cancer at the same time period, and made up 3.5% of all patients (3,176 cases) with multiple primary cancers, and 21.7% of all patients (517 cases) with breast cancer who developed multiple primaries. Results. The most frequent type of synchronous primary malignancy was breast cancer (63.4%) and 90.1% of them were diagnosed at the same time or within one month following the first breast cancer diagnosis. Among cases of non-breast synchronous primaries, female genital organ malignancies were predominant (36.6%). Synchronous breast cancer was diagnosed significantly earlier than non-breast cancers (mean time was 0.4 and 1 month, respectively, p = 0.0123). Better results in the group with synchronous contralateral breast cancer in comparison to synchronous breast and non-breast cancer were observed (5-year overall survival rates were 90.9% and 66.3%, respectively, and 5-year disease-free survival rate — 62.5% and 51.3%, respectively).

Objective: Wound infection after intestinal ostomy closure is a very common postoperative complication. An alternative to primary wound suturing by single sutures or purse string sutures (PSS) is applying incisional negative pressure wound therapy (iNPWT). The aim of the following systematic review and meta-analysis was to assess and compare clinical outcomes in patients after PSS and iNPWT use. Approach: The aim of the study was to find relevant clinical data comparing outcomes of iNPWT and primary wound closure after intestinal ostomy closure. The search was conducted using the MEDLINE/PubMed, ScienceDirect, EMBASE, Scopus, Cochrane Controlled Register of Trials, SciELO, and Web of Science databases and took place up to November 12, 2022. The authors did not use date or language filters. Statistical analysis was performed using Review Manager 5.4 (The Cochrane Collaboration, 2020, London, UK). The authors conducted a meta-analysis of the following four parameters: wound healing time (WHT), surgical site infections (SSIs), complications, and length of hospital stay (LOS). Odds ratios (OR) and inverse variance (IV) were generated with 95% confidence intervals (CI). The meta-analysis was registered in the International Prospective Register of Systematic Reviews database under registration number CRD42023391640. Results: The analysis revealed that the iNPWT group and the control group did not differ significantly with regard to the WHT parameter (Z = 2,73; p = 0.006; χ ² = 0.37, df = 1, p = 0.54, I ² = 0%). Meta-analysis of SSI incidence revealed a significant difference favoring the iNPWT group over the observational group (OR = 0.42; 95% CI = 0.25–0.72; p = 0.002; I ² = 14%). Patients included in the iNPWT group had a significantly lower pooled incidence of overall complications than the observational group (OR = 0.52; 95% CI = 0.35–0.77; p = 0.001, I ² = 71%). Subgroup analysis limited to randomized studies also presented significant differences favoring the iNPWT group over the observational group (OR = 0.27; 95% CI = 0.14–0.52; p < 0.001, I ² = 67%). Our analysis showed that LOS did not differ significantly between the groups treated with and without iNPWT (IV = 0.19; 95% CI = −0.66 −1,04; p = 0.76, I ² = 0%). In addition, subgroup analysis of randomized studies also did not present a significant difference (IV = 0.25; 95% CI = −0.80 −1,30; p = 0.33, I ² = 10%). Innovation: This study shows that the use of iNPWT can reduce the risk of SSIs with other complications, such as wound hematomas, wound seromas, wound dehiscence, fistulas, and ileus, in patients undergoing intestinal ostomy closure without extended hospital stay. Conclusions: Use of iNPWT can be considered in postoperative care after elective ostomy closure to decrease the rate of the most common complications after ostomy closure.
