Dermatologic complications of anti-PD-1/PD-L1 immune checkpoint antibodies

Purpose of review: The therapeutic use of anti-PD-1/PD-L1 antibodies (nivolumab, pembrolizumab) is rapidly increasing. Given their mechanism of action that triggers T-cell activation, these immune checkpoint inhibitors induce specific adverse events that are mostly of immunologic origin. In this way, cutaneous toxicities represent the most frequent immune-related adverse events (irAEs). The purpose of this review is to summarize the most prevalent dermatologic complications induced by PD-1/PD-L1 immune checkpoint-blocking antibodies and to compare their dermatologic safety profile with anti-CTLA-4 ipilimumab. Recent findings: More than 40% of melanoma patients treated with anti-PD-1 therapy are faced with dermatologic irAEs. However, these cutaneous complications usually remain self-limiting and readily manageable. Nonspecific macular papular rash and pruritus represent the most common manifestations. More characteristic lichenoid dermatitis or psoriasis may also develop. Vitiligo is also frequent in patients with melanoma but has not been reported in other types of solid cancers. Mucosal involvement may also occur, including xerostomia and lichenoid reactions. Although available data remain scarce, anti-PD-L1 antibodies present a similar dermatologic safety profile. Summary: Dermatologic irAEs induced by PD-1 or PD-L1 blockade therapy rarely result in significant morbidity or permanent discontinuation of treatment. However, early recognition and appropriate management are ...

Authors: Lancellotti P, De Pauw M, Claeys M Abstract Cardiovascular disease (CVD) and cancer represent the two main causes of death in industrialised countries. Both share common risk factors (diabetes, obesity, hypertension, diet, smoking, etc.). The associated timing of CVD and cancer onset is thus largely influenced by modifiable risk factors. Advances in cancer treatment have extended the lives of patients with cancer, but for some at the cost of adverse cardiovascular events. The rapidly growing number of patients surviving cancer, often in the setting of advanced age, new or pre-existing CV disease and risk f...

Authors: Lai G, Guo N, Jiang Y, Lai J, Li Y, Lai R Abstract OBJECTIVE: To assess whether the duration of one-lung ventilation (OLV) affects postoperative pulmonary complications after McKeown esophagectomy for esophageal cancer. METHODS: A retrospective analysis of data stored in a database for esophageal cancer was carried out to identify predictors of postoperative pulmonary complications in patients undergoing McKeown esophagectomy at Sun Yat-sen University Cancer Center between 2010 and 2012. RESULTS: Patients in the OLV ⩾150 minutes group had a higher incidence of postoperative pulmonary complication...

Authors: Wang XQ, Zheng Y, Fang PF, Song XB Abstract The lack of reliable plasma biomarkers limits their use in the diagnosis of gastric cancer (GC). The current study aimed to determine whether plasma nesfatin-1 can be used as a novel non-invasive biomarker for the diagnosis of GC. The levels of nesfatin-1 in 40 patients with GC and 40 healthy individuals, who were selected from the Chaohu Hospital Affiliated to Anhui Medical University, were assessed. ELISA was used for the measurement of plasma nesfatin-1 levels, while immunohistochemistry was applied to determine Ki67 protein expression in GC and normal gastric...

Authors: Ren L, Li Y, Zhao Q, Fan L, Tan B, Zang A, Yang H Abstract Breast cancer is one of the most prevalent types of cancer among women that leads to millions of deaths worldwide every year. The mechanisms of breast cancer pathogenesis remain unclear. It has been reported that aberrant expression of miR-519, is associated with breast cancer development; however, the effects of miR-519 on breast cancer cell proliferation remain unknown. Therefore, the present study aimed to determine whether miR-519 could regulate breast cancer cell proliferation. A total of 20 pairs of primary breast cancer and adjacent normal t...

Although the use of Nivolumab prolongs survival in a number of patients, this treatment is hampered b...

In conclusion, cfDNA and cftDNA exhibit the potential to become novel biomarkers for the response assessment following cancer treatment, and may serve as a tool for the estimation of tumor volume. The current study further supports the increasingly important role of cfDNA and cftDNA as new monitoring tools for use during cancer therapy. PMID: 31966080 [PubMed]

This study aimed to reveal the clinical significance of serum melatonin levels in predicting the severity of oral squamous cell carcinoma (OSCC). For this purpose, 40 male patients with OSCC and 30 healthy subjects were enrolled in this study. The serum levels of melatonin were determined by ELISA. The results revealed that the melatonin concentrations were significantly lower in the patients with OSCC compared with the controls (18.2 vs. 47.6 pg/ml, P
