PurposeThe purpose of this study was to set up a prognostic model for the identification of survival predictors specific for melanoma patients treated with ipilimumab.Experimental designThe following prospectively collected data were utilised: patient and primary tumour characteristics, relapse-free-interval, site and number of metastases, previous therapies and level of serum biomarkers (lactic dehydrogenase (LDH), C-reactive protein, β2-microglobulin, vascular endothelial growth factor (VEGF), IL2, IL6, S-100, alkaline phosphatase (ALP), transaminases, leucocyte count, lymphocytes subpopulations). A multivariate prognostic model was developed using the Cox regression model fitted to the data of 113 consecutive metastatic patients treated with ipilimumab (3 mg/kg, q3w) at Veneto Institute of Oncology (IOV). External validation was obtained using the data of 69 and 34 patients treated at European Oncology Institute (IEO) and University of Torino (UT), respectively.ResultsMedian survival was 8.3, 4.9 and 7.1 months from first ipilimumab administration at IOV, IEO and UT, respectively. Both higher baseline levels of LDH (Hazard Ratio [HR] v = 1.36, 95% Confidence Interval [CI] 1.16–1.58, P < .001) and neutrophils (HR = 1.76, 95% CI 1.41–2.10, P < .001) were associated with worse prognosis. Model performance was satisfactory both upon internal validation (Dxy = 0.42) and external validation (Dxy = 0.40). Serum LDH and neutrophil count discriminated patients who lived more (low neutrophils and low LDH) or less (high LDH or neutrophils) than 24 months.ConclusionSerum LDH and neutrophil count were significant independent prognostic factors. This externally validated prognostic nomogram, could help clinicians to identify the patients who would benefit most from ipilimumab and consequently to improve resource allocation. These easily available biomarkers deserve further validation. 相似文献
BackgroundImmunotherapies like the cytotoxic T-lymphocyte antigen 4 inhibitor ipilimumab show durable clinical benefit in patients with advanced melanoma. Reliable prognostic markers and risk scores in the era of immunotherapy are still lacking.Patients and methodsWe collected characteristics and outcomes on 134 patients with metastatic melanoma treated with ipilimumab between 2011 and 2014 at a single centre. Cox regression including multivariable fractional polynomials was used to identify independent markers for overall survival (OS). Internal model validation was done using bootstrap procedures.ResultsAfter a median follow-up of 16.1 months the median OS was 7.1 months (95% confidence interval [CI], 6.5–9.8). Nineteen of 134 patients (14.2%) had tumour remissions, 16 partial and 3 complete; 75% had progressive disease. We identified three independent adverse factors for OS: elevated lactate dehydrogenase (LDH) (hazard ratio [HR] 1.03, 95% CI 1.02–1.04), Eastern Cooperative Oncology Group performance status >0 (HR 1.91, 95% CI 1.10–3.30), and number of organs involved (NOI) (HR 1.51, 95% CI 1.22–1.86). To build an easy-to-apply risk score, we dichotomized LDH (>upper limit of normal) and NOI (>2) to built 3 prognostic groups: favourable (no adverse factors, N = 17), intermediate (1 adverse factor, N = 38), and poor prognosis (≥2 adverse factors, N = 73). Respective 12 and 18-month OS for the risk groups were: 85% and 73% (favourable), 41% and 29% (intermediate), and 12% and 6% (poor) (p < 0.001).ConclusionWe propose a simple prognostic score for survival in patients with advanced melanoma treated with ipilimumab using readily available clinical parameters. 相似文献
Due to resistance and immune-related adverse events (irAE) some melanoma patients require ipilimumab after nivolumab therapy. However, little is known about the result of this switching.
Objective
Investigate the outcome of ipilimumab switching in Japanese patients.
Methods
We retrospectively collected 60 patients who were treated with ipilimumab after nivolumab from 9 institutes in Japan. Information of the primary tumor, treatment, response, irAE), and survival was collected.
Results
In our cohort, acral lentiginous and mucosal melanoma accounted for 53% of the cases. The most common reason for initiating ipilimumab was disease progression (93%). Median interval from the last nivolumab administration to first ipilimumab administration was 29 days. Only 38% of patients completed 4 injections of ipilimumab. The best overall response was 3.6%. IrAE occurred in 78% of patients and 70% of those were of grade 3/4 (G3/4) and 31% of patients experienced 2 or more irAEs. An within interval of 28 days or less between the last nivolumab administration and ipilimumab administration was correlated with the development of G3/4 pyrexia and 3 or more irAEs, but irAE occurrence did not affect survival. Multivariate analysis showed that endocrine irAE (relative risk = 0.22, P = 0.015) and skin irAE (relative risk = 2.78, P = 0.048) were significant factors associated with survival.
Conclusion
In our study, the response ratio to ipilimumab after nivolumab was unsatisfactory and associated with a high frequency of severe irAEs. As there are few second-line treatment options for patients with BRAF wild-type advanced melanoma after nivolumab failure, patients should be closely monitored if ipilimumab is initiated. 相似文献
Introduction: The treatment of melanoma is evolving rapidly over the past few years.
Areas covered: We conducted a comprehensive review of the literature on the role of nivolumab in melanoma
Expert commentary: Nivolumab is approved by FDA and EMA for the treatment of patients with metastatic melanoma. Nivolumab is superior to chemotherapy and to ipilimumab in previously untreated patients and to chemotherapy in ipilimumab pre-treated patients. The addition ipilimumab to nivolumab is associated with a higher response rate and a better PFS, particularly in patients with PD-L1 negative tumors, albeit at the cost of an increase in grade 3–4 adverse event rate. Definitive survival data on this combination are pending and the selection of patients most likely to benefit from this combination and its pharmacoeconomics are to be elucidated. Prospectively validated predictive markers are lacking. Of particular interest are immune-related adverse events which should be managed according to published guidelines. 相似文献
The use of immune checkpoint inhibitors (ICI) has grown incessantly since they were first approved in 2014. These monoclonal antibodies inhibit T cell activation, yielding a dramatic tumor response with improved survival. However, immunotherapy is frequently hampered by immune adverse events (iAE) such as hypophysitis, colitis, hepatitis, pneumonitis and rash. Until recently, rheumatic side effects were only infrequently reported.
Aim
To describe the rheumatic manifestations encountered among patients treated with ICIs in a large tertiary cancer center in Israel
Methods
The cancer center's patient registry was screened for patients who had ever been treated with ipilimumab, pembrolizumab and/or nivolumab with relevant data gathered from clinical charts.
Results
Rheumatic manifestations were encountered in 14 of 400 patients (3.5%) who had received immunotherapy between January 1st 2013 and April 30th, 2017. The most common rheumatic manifestation was inflammatory arthritis (85%) for which a third (4/11) had a clear cut predisposing factor such as a personal or family history of psoriasis, a prior episode of uveitis or ACPA positivity. Pulmonary sarcoidosis and biopsy-proven eosinophilic fasciitis were diagnosed in two additional patients. Treatment with NSAIDS was mostly unsuccessful while steroid therapy was beneficial in doses ≥20?mg/d. Methotrexate enabled steroid tapering without an excess of side effects or tumor progression in the short follow-up available. Overall, rheumatic manifestations tended to occur later in the course of immunotherapy as compared to other iAE.
Conclusions
Our findings underscore that rheumatic iAE are part of the side effect profile of ICIs and require heightened awareness as these therapies are becoming the standard of care for various malignancies. We show that these appear later in the course of iAEs and respond preferentially to high dose steroids. MTX appears effective as a steroid sparing agent. 相似文献
The randomised phase III clinical trial Checkmate-214 showed a survival superiority for the combination of ipilimumab and nivolumab when compared with the previous standard of care in first-line metastatic/advanced clear cell renal cell carcinoma (RCC) (Escudier B, Tannir NM, McDermott DF, et al. CheckMate 214: efficacy and safety of nivolumab plus ipilimumab vs sunitinib for treatment-naïve advanced or metastatic renal cell carcinoma, including IMDC risk and PD-L1 expression subgroups. LBA5, ESMO 2017, 2017). These results change the frontline standard of care for this disease and have implications for the selection of subsequent therapies. For this reason the European Association of Urology RCC guidelines have been updated.
Patient summary
The European Association of Urology guidelines will be updated based on the results of the phase III Checkmate-214 clinical trial. The trial showed superior survival for a combination of ipilimumab and nivolumab (IN), compared with the previous standard of care, in intermediate- and poor-risk patients with metastatic clear cell renal cell carcinoma. When IN is not safe or feasible, alternative agents such as sunitinib, pazopanib, and cabozantinib should be considered. Furthermore, at present, the data from the trial are immature in favourable-risk patients. Therefore, sunitinib or pazopanib remains the favoured agent for this subgroup of patients. 相似文献
Metastatic melanoma is one of the most deadly forms of cancer and is poorly responsive to standard chemotherapeutics, such as Dacarbazine and Paclitaxel. Recently, the advent of Vemurafenib and Ipilimumab has broadened the spectrum of therapeutic options for advanced melanoma patients but the occurrence of resistance and of high-grade toxicities call for better and more effective treatments. This review focuses on approved and experimental therapies for metastatic melanoma. The mechanism of action and the reported efficacy data for small molecule drugs and biologics are discussed, outlining directions for future pharmaceutical research in this field. 相似文献

The development of brain metastases is common in patients with metastatic melanoma and heralds a particularly poor prognosis. The development of the immunological agent ipilimumab and targeted treatments such as the selective BRAF inhibitor vemurafenib have revolutionised the treatment of metastatic disease. Evidence from clinical trials suggest these drugs may be effective in the treatment of brain metastases from melanoma. However efficacy may be limited by a lack of penetration of the blood brain barrier (BBB) and by multi substrate efflux pumps expressed on the BBB. The role and sequencing of radiotherapy, both whole brain and stereotactic radiotherapy, is yet to be determined but combinations of radiotherapy and systemic therapies may further increase the effects of these drugs on brain metastases. Considering the impact of brain metastases on morbidity and mortality in metastatic melanoma, future research into systemic drug therapy for the treatment of brain metastases and improvements in BBB penetrance should be a priority. 相似文献
