No full textPrognostic and Predictive Factors in Advanced Urothelial Carcinoma Treated with Immune Checkpoint Inhibitors: A Review of the Current Evidence
No full textIn recent years, the treatment landscape of urothelial carcinoma has significantly changed due to the introduction of immune checkpoint inhibitors (ICIs), which are the standard of care for second-line treatment and first-line platinum-ineligible patients with advanced disease. Despite the overall survival improvement, only a minority of patients benefit from this immunotherapy. Therefore, there is an unmet need to identify prognostic and predictive biomarkers or models to select patients who will benefit from ICIs, especially in view of novel therapeutic agents. This review describes the prognostic and predictive role, and clinical readiness, of clinical and tumour factors, including new molecular classes, tumour mutational burden, mutational signatures, circulating tumour DNA, programmed death-ligand 1, inflammatory indices and clinical characteristics for patients with urothelial cancer treated with ICIs. A classification of these factors according to the levels of evidence and grades of recommendation currently indicates both a prognostic and predictive value for ctDNA and a prognostic relevance only for concomitant medications and patients' characteristics
Feasibility of multiple immunoexpression assay for immune tumor micrornvironment (I-TME) on matched metastatic and primary renal cell carcinoma (RCC) for patient prognostication and predictiveness to immunotherapy (preliminary analyses of the Meet URO 18 study).
No full textBackground: The Meet-URO 18 study is ongoing to assess the prognostic role of I-TME in advanced RCC patients treated with ≥second line nivolumab divided into two cohorts according to clinical benefit [progression-free survival ≥ 12 and ≤ 3 months]. We primarily assessed the feasibility of multiple antibody testing related to I-TME on matched metastases and primary tumor. Methods: Immunohistochemical analyses were used for the TME assessment of T-lineage (CD3, CD4, CD8), FOXP-3, granulocytes (CD15), macrophage-lineage (CD68), natural killer (NK)-cells (CD56), tumor cells (TCs) (CD56), B-lineage (CD20) and phosphorylated mTOR (phmTOR). TCs were quantitatively assessed for CD15, CD56 and phmTOR positivity. For T-, B- and CD68 cells within TC nests, the number of immunoreactive cells were counted with a microscopic field of x200 (0.933 mm2). Results: Overall, 42 tumor tissue samples (primary tumors, metastases) were available and for 17 patients both metastatic and primary tumor tissues were assessable for matched analyses. Among these patients, 12 had clear cell, 1 papillary and 4 mucinous tubular and spindle cell histotype according to WHO 2016 classification. Intratumoral T/CD8 cells ranged from 32 to >400 spots (mean 240; >400 in 7 samples) and intratumoral T/CD4 cells from 4 to >400 spots (mean 168; >400 in 5 samples). Nine samples showed absence of phmTOR expression, while 8 ranged from 10% to 90% of positive TCs. We did not observe countable NK-cells, whereas CD56 was visible in 5 samples (mean 55% of positive TCs). Intratumoral CD68 cells ranged from 34 to >400 spots (mean 175, >400 in 3 patients). Agreement of CD15 method of reporting granulocytic presence was high, thus only CD15 neoplastic expression was reported and ranged from 12% to 55% (mean 30%) in 15 patients. TME multiple analysis resulted equally clustered in 8 patients (<20% variability of single immuno-test) whereas the remaining 9 patients showed significant differences as percentage of immuno-tissue expression in at least one of the 5 immuno-indicators (T/CD8-CD4, C15, CD68, CD56, phmTOR). The remaining 8 samples of patients without matched analyses were used to test the feasibility of multiple analyses; among all antibodies exclusion of the CD20 and FOXP-3 final evaluation was needed, due to technical standardization. According to the 5 immuno-indicators, double-triple positive or penta-positive TME indicators may be identified and graded. Conclusions: Providing multiple immunoexpression platforms on a single specimen may be used as routine workflow. Profiling I-TME, especially CD56, CD15 on TCs and CD68 cells and phmTOR, deserves investigation with extensive control groups. A validation cohort will be tested at tissue level and in correlation with peripheral blood markers
Early primary tumor response in metastatic RCC patients treated with immune checkpoint inhibitors-based combinations
No full textBackground:
25-30% of renal cell carcinoma presents with metastases (mRCC) at diagnosis.
The activity of immune checkpoint inhibitor (ICI)-combinations on the primary tumor (PT) is debated.
Patients andMethods:
mRCC patients (pts) with PT who received first-line nivolumab plus ipilimumab (N/I) or pembrolizumab plus axitinib (P/A) were included. We investigated the early primary tumor response (EPTR) at the first radiological assessment.
Results:
73 pts were included. The median early reduction of the PT longest diameter was 12.4% with P/A versus 6.2% with N/I (p = 0.42). We evaluated if the type of EPTR could affect the metastases response. Among pts with PT stable disease (SD), 8.3% had metastatic disease progression (PD) with P/A and 34.8% with N/I. Early PT partial response (PR) was associated with no metastatic PD with both N/I and P/A. The 2 pts with PT PD had also metastatic PD to P/A. Of the 3 PT with PD to N/I, 1 had metastatic SD and 2 PD. In the overall population, of the 94.1% without PT progression (PR+SD), 47.5% had metastatic PR, 35.6% SD, 16.9% PD.
Conclusions:
ICIs-combinations achieved an early PT PR in about 10-20%, without any complete responses. Only a small percentage of PT had an early PD, mainly associated with metastatic PD. However, among those PT without an early progression, metastatic PR can be achieved in approximately 50% of cases
Combined response of advanced cutaneous squamous cell carcinoma and renal cell carcinoma to immunotherapy: a case report
No full text: Immune checkpoint inhibitors have significantly improved the therapeutic scenario of many different advanced malignancies and could be an effective treatment strategy in synchronous or metachronous tumors. The authors describe the clinical case of a patient who experienced a long-lasting response of his metastatic renal cell carcinoma and an optimal response of his locally advanced cutaneous squamous cell carcinoma to immunotherapy. The systemic treatment was chosen based on a literature review of several clinical reports, since there was no prospective study on anti-PD-1 blockade activity in cutaneous squamous cell carcinoma when the patient started the treatment. This clinical case supports the growing evidence for immunotherapy as a valid treatment option across different types of advanced tumors
Apalutamide-induced lichenoid reaction in a patient with non-metastatic castrate-resistant prostate cancer
No full textIntroduction Apalutamide is an oral selective androgen receptor inhibitor, approved by the FDA for the treatment of patients with non-metastatic, castration-resistant prostate cancer (M0 CRPC) at high risk of developing metastases and for patients with metastatic castration-sensitive prostate (mHSPC) in association with androgen deprivation therapy (ADT). In the registration studies, skin reactions were reported among the most common side effects and as an adverse event of special interest. Case Report Apalutamide-induced rash includes a wide spectrum of different types of skin reactions, but few cases reports and case series have described this adverse event. Here, we report an M0 CRPC patient who experienced a rare skin adverse event, a lichenoid reaction. Management & Outcome After 4 months of therapy with apalutamide, the patient reported dorsal pricking and dry skin. Lichenoid reaction was confirmed histologically and its correlation to the drug was demonstrated after pursuing a multidisciplinary approach. Discussion To our knowledge, this is one of the first cases of Apalutamide-related lichenoid reaction and this clinical case showed the relevance of a multidisciplinary management when assessing drug-related adverse events. A broader knowledge of the spectrum of drug-related reactions would allow for a better diagnosis and therapy management by both physicians and patients
Correlation of the immune tumor microenvironment (I-TME) with gene expression profiles as prognostic and predictive factors in patients (pts) with metastatic renal carcinoma (mRCC) treated with immunotherapy (Meet-URO 18 I-TME study)
No full textBackground: Several studies suggested that response to immunotherapy may be influenced by many factors, including peripheral blood biomarkers, the composition of I-TME and different molecular expression pathways. In mRCC patients, immunotherapy has become part of clinical practice, but the identification of patients most likely to respond to checkpoint inhibitors is still an unmet clinical need. Moreover, there are no validated and clinically applicable gene expression panels as prognostic and/or predictive response biomarkers. To date, three major groups of immune-related gene expression were identified in mRCC: the angiogenesis pathway, the T-effector pathway and the mixed pathway (doi: 10.1038/s41598-020-58804-y). Each group of gene expression seems to be responsible for a different type of immune response in the I-TME. However, a significant association with treatment response to immunotherapy has not yet been demonstrated. Methods: The Meet-URO 18 is a multicentric retrospective translational study aimed at identifying distinctive molecular patterns of the I-TME with a prognostic and predictive role in mRCC (primary objective). Pretreated mRCC patients receiving ≥2nd line nivolumab have been divided according to clinical benefit in responders (PFS ≥ 12 months) versus non-responders (PFS ≤ 3 months). Secondary objectives include the correlation between primary tumor and metastases to identify a potential inter-tumor heterogeneity and the correlation with survival and response outcomes. Histological samples of primary tumors and/or metastases have been collected for the transcriptomic analyses together with clinical data of patients from medical records. The transcriptomic characterization of the I-TME of the primary tumor and/or metastases will be performed using the analytical platform "nCounter" of NanoString®, which analyzes the expression of 71 genes involved in angiogenesis, immunomodulation mediated by T-effector response, mechanisms of tumor invasion and mechanisms of calcium channel flows. The gene-panel include a group of 66 genes previously demonstrated to be related in the immune-response in mRCC (doi: 10.1038/s41598-020-58804-y) and 5 housekeeping genes (RPS13, PPIA, RPL27, RP2, B-ACT)
Prognostic stratification by the Meet-URO score in real-world older patients with metastatic renal cell carcinoma (mRCC) receiving cabozantinib: a subanalysis of the prospective ZEBRA study (Meet-URO 9).
No full textBackground: The addition of neutrophil to lymphocyte ratio (NLR) and bone metastases to the IMDC classification provided by the Meet-URO score, resulted in higher prognostic accuracy in metastatic renal cell carcinoma (mRCC) patients receiving ≥2nd line nivolumab or cabozantinib in 2 retrospective analyses and 1st line nivolumab-ipilimumab in an expanded access programme. Prognostic estimates for older mRCC patients might be key for clinical decision-making. Methods: The outcome of real-world older (≥70 years) mRCC patients treated with any line cabozantinib within the multicenter observational prospective ZEBRA (Meet-URO 9) study was analyzed according to the baseline Meet-URO score. The primary endpoint was overall survival (OS). The discriminative ability by Harrell's c-index and calibration were assessed to compare the Meet-URO and IMDC scores. Results: A total of 104 mRCC patients received cabozantinib as 1st (38%), 2nd (20%), or ≥3rd (41%) line. With a median follow-up of 11.2 months, the median OS (mOS) was of 18.4 months. According to the IMDC score, favorable (15%), intermediate (65%) and poor-risk (19%) patients had a mOS not reached, of 15.6 and 5.7 months respectively (p = .011). According to the Meet-URO score groups, mOS was not reached in both group 1 (10%) and group 2 (25%), while in group 3 (33%), group 4 (25%) and group 5 (8%) mOS was of 13.6, 12.5, and 3.7 months, respectively (p < .001). The discriminative ability of the Meet-URO score was maintained by merging groups 1 to 2 vs. 3 to 4 vs. 5 (p < .001). The Meet-URO score (with either the original 5-group stratification or the modified 3-group one) showed higher accuracy than the IMDC score (c-index of 0.686 and 0.676 vs. 0.622). Conclusion: This analysis confirmed the prognostic accuracy of the Meet-URO score in older mRCC patients treated with cabozantinib and its role as a convenient tool for informing the patient and clinical decisions
