RESUMEN
Cardiac toxicity is an adverse event of several classes of anti-cancer drugs. Herein, we present the case of a 52-year-old woman with metastatic renal cell carcinoma (RCC), previously treated with debulking surgery, pembrolizumab (immune checkpoint inhibitor) in combination with axitinib (tyrosine kinase inhibitor (TKI)), followed by lenvatinib (TKI) and belzutifan (HIF-2α inhibitor), who developed myocarditis proven by cardiac magnetic resonance and endomyocardial biopsy. The case was notable for reporting a not-yet described adverse event during treatment with belzutifan plus lenvatinib, the etiology of which was of unobvious determination given the pre-exposure to pembrolizumab, a known cause of drug-related myocarditis. We surmise that myocarditis was a delayed adverse event related to pembrolizumab (8 months after treatment interruption), although we emphasize that only attentive monitoring of cardiac adverse events of patients exposed to belzutifan and lenvatinib in the context of large clinical trials may rule out any causal implication of these drugs.
RESUMEN
CONTEXT: Genitourinary cancers (GUCs) encompass malignancies affecting the urinary and reproductive systems, including renal cell carcinoma (RCC), urothelial carcinoma (UC), and prostate cancer (PC). With the rapidly evolving therapeutic domain of these cancers, cutaneous adverse events (AEs) remain among the most observed toxicities. OBJECTIVE: To explore the dermatologic AEs linked to novel GUC treatments, their underlying pathophysiology, clinical presentations, and risk factors. EVIDENCE ACQUISITION: A narrative review of the literature from PubMed and Embase databases was conducted. The search strategy included dermatologic/cutaneous adverse events, risk factors, and pathophysiology in conjunction with the following classes of therapies; immune checkpoint inhibitors (ICIs), antiangiogenic therapies, enfortumab vedotin (EV), erdafitinib, and androgen receptor antagonists (ARAs). EVIDENCE SYNTHESIS: Maculopapular rash, pruritus, and alopecia are present among the five classes of therapies. ICIs demonstrate the highest incidence of severe drug AEs including Steven Johnson syndrome/toxic epidermal necrolysis. Unique cutaneous AEs present with specific therapies including hand-foot skin reaction and subungual splinter hemorrhage with antiangiogenic drugs, stomatitis/mucositis and onycholysis with erdafitinib. Incidence and type of cutaneous AE also differed within therapies in the same class as seen with apalutamide displaying the highest risk of cutaneous AEs within ARAs. Risk factors for development of cutaneous AEs can be general to therapies, or specific, and include age, immune status, BMI, and gender. CONCLUSIONS: Dermatologic AEs may impact patients' quality of life and increase the tendency to dose reduce, hold or discontinue life-saving therapies, underscoring the need for vigilant monitoring, early recognition, and collaborative management between medical oncologists, pharmacists, dermatologists and other specialists.

BACKGROUND: The application of precision medicine in clinical practice implies a thorough evaluation of actionable genomic alterations to streamline therapeutic decision making. Comprehensive genomic profiling of tumor via next-generation sequencing (NGS) represents a great opportunity but also several challenges. During the 2023 San Raffaele Retreat, we aimed to provide expert recommendations for the optimal use of NGS in urothelial carcinoma (UC). MATERIALS AND METHODS: A modified Delphi method was utilized, involving a panel of 12 experts in UC from European and United States centers, including oncologists, urologists, pathologists, and translational scientists. An initial survey, conducted before the meeting, delivered 15 statements to the panel. A consensus was defined when ≥70% agreement was reached for each statement. Statements not meeting the consensus threshold were discussed during the meeting. RESULTS: Nine of the 15 statements covering patient selection, cancer characteristics, and type of NGS assay, achieved a consensus during the survey. The remaining six statements addressing the optimal timing of NGS use, the ideal source of tumor biospecimen for NGS testing, and the subsequent need to evaluate the germline nature of certain genomic findings were discussed during the meeting, leading to unanimous agreement at the end of the conference. CONCLUSION: This consensus-building effort addressed multiple unanswered questions regarding the use of NGS in UC. The opinion of experts was in favor of broader use of NGS. In a setting where recommendations/guidelines may be limited, these insights may aid clinicians to provide informed counselling and raise the bar of precision and personalized therapy.

BACKGROUND: Recent progresses in the use of immune checkpoint inhibitor (ICI) have challenged the therapeutic standards in patients with muscle-invasive urothelial bladder carcinoma (MIBC). OBJECTIVE: To compare neoadjuvant pembrolizumab followed by radical cystectomy (RC) versus neoadjuvant chemotherapy (NAC) and RC or upfront RC, according to cisplatin eligibility. DESIGN, SETTING, AND PARTICIPANTS: We conducted two separate analyses for cisplatin-eligible and cisplatin-ineligible cT2-4N0M0 MIBC patients. We used a propensity score adjustment that relied on inverse probability of treatment-weighting (IPTW). INTERVENTION: Pembrolizumab within the PURE-01 trial, and NAC and RC or upfront RC from a high-volume tertiary care referral center. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary endpoint in both analyses was event-free survival (EFS), defined as freedom from recurrence, and/or death from any cause indexed from the date of treatment initiation or RC. The secondary endpoints included EFS in propensity score-matched patients, pathologic response rate, and recurrence-free survival (RFS) after RC. RESULTS AND LIMITATIONS: A total of 458 patients who underwent RC, with or without NAC, at Moffitt Cancer Center between October 2005 and October 2020, and 146 patients enrolled in PURE-01 were analyzed. In cisplatin-ineligible patients, EFS was superior in those receiving pembrolizumab (p < 0.001). The estimated 3-yr EFS was 77.8% (95% confidence interval [CI]: 63.5-95.2) for pembrolizumab and RC, and 36.1% (95% CI: 28.6-45.5) for upfront RC. EFS remained superior in those receiving neoadjuvant ICI (NICI) following IPTW (p < 0.001). In cisplatin-eligible patients, EFS was superior in those receiving pembrolizumab and RC (p < 0.001). The estimated 3-yr EFS was 86.9% (95% CI: 80.9-93.3) for pembrolizumab and 63.5% (95% CI: 56.5-71.4) for NAC. EFS remained superior in those receiving NICI following IPTW (p < 0.001). Pathologic responses and RFS in pembrolizumab-treated patients were also superior to those in NAC-treated patients. Results are limited by the retrospective nature of the study. CONCLUSIONS: In the first ever reported comprehensive comparison of outcomes between neoadjuvant ICI and NAC, followed by RC, or upfront RC, we report increased responses and improved oncologic outcomes with neoadjuvant ICI in patients with MIBC. PATIENT SUMMARY: We compared the results obtained from the use of pembrolizumab and radical cystectomy with standard-of-care treatments in patients with bladder carcinoma infiltrating the muscle layer. We reported increased response and survival rates possibilities with the use of immunotherapy, anticipating the possibility to set new therapeutic standards in these patients, pending the results of ongoing randomized studies.

Despite the significant improvements in the field of oncological treatments in recent decades, and the advent of targeted therapies and immunotherapy, urothelial carcinoma of the bladder remains a highly heterogeneous and difficult-to-treat neoplasm with a poor prognosis. In this context, owing to the new methods of genomic sequencing, numerous studies have analyzed the genetic features of muscle-invasive bladder cancer, providing a consensus set of molecular classes, to identify malignancies that may respond better to specific treatments (standard chemotherapy, immunotherapy, target therapy, local-regional treatment, or combinations) and improve the survival. The aim of the current review is to provide an overview of the current status of the molecular landscape of muscle-invasive bladder cancer, focusing our attention on therapeutic and prognostic implications in order to select the most effective and tailored therapeutic regimen for the individual patient.

OBJECTIVE: To evaluate the predictive capability of the pre- and post-pembrolizumab Vesical Imaging-Reporting and Data System (VI-RADS) to identify ypT0N0 or ypT≤1N0 response in muscle-invasive bladder cancer (MIBC) within the PURE-01 trial (ClinicalTrials.gov identifier: NCT02736266). PATIENTS AND METHODS: Patients were staged with bladder multiparametric magnetic resonance imaging (mpMRI) before and after treatment (three cycles of pembrolizumab) prior to radical cystectomy (RC). Logistic regression models were used to analyse the pre- and post- pembrolizumab VI-RADS against ypT≤1N0 and ypT0N0 response. The VI-RADS scores were dichotomised between 0 and 3 (0 = no evidence of disease) and 4-5. Event-free survival (EFS) and overall survival (OS) analyses were performed. Comprehensive genomic profiling and transcriptome-wide expression profiling data were matched with the VI-RADS scores. RESULTS: In total, 110 patients underwent centrally reviewed scans (N = 220 mpMRI), treated between February 2017 and July 2020. Both pre- and post-pembrolizumab VI-RADS 0-3 scores were the only significant covariates that predicted the ypT≤1N0 endpoint in multivariable analyses, and the strongest effect was seen with post-pembrolizumab VI-RADS 0-3 predicting the ypT≤1N0 response (P < 0.001). The area under the curve for this model was 0.90. Post-pembrolizumab VI-RADS 0-3 also predicted a longer EFS (P < 0.001) and OS (P = 0.044). The scores of several gene signatures from baseline tumours differed between the pre-pembrolizumab VI-RADS 0-3 and 4-5 categories. CONCLUSION: Post-pembrolizumab VI-RADS scores are strongly associated with pathological downstaging and survival. VI-RADS scores were also characterised by distinct biomarker features. These results indicate that the VI-RADS is emerging as an important tool for designing next-generation trials for MIBC.

BACKGROUND: TERT promoter mutation is one of the most common genomic alterations in urothelial carcinoma (UC). Its prognostic role on patients' outcomes is still not clear. METHODS: We performed a single-center retrospective analysis on patients with advanced UC treated with platinum-based chemotherapy or immunotherapy to assess the presence of somatic TERT-124[C>T] and TERT-146[C>T] mutations and their association with clinicopathologic factors and survival outcomes. Patients were assessed for Overall Survival (OS), Progression-Free Survival (PFS), and Overall Response Rate (ORR). RESULTS: We analyzed 45 UC tumors; 38 of them received first-line chemotherapy and 21 second-line pembrolizumab; 6 patients (13%) harbored -146 C > T TERTp mutation and 25 patients (56%)-124 C > T. The presence of TERT promoter mutations was associated with a higher rate of lower tract UC and a lower rate of synchronous or lymph node metastases. TERT wild-type patients showed higher 12- and 24-months OS-rates in the chemotherapy subgroup and 6-, 12- and 24-months OS rates in the pembrolizumab subgroup. The presence of TERT promoter mutations was also associated with a lower 6 months-PFS rate in patients receiving chemotherapy and in all the three time points in those treated by pembrolizumab. The ORRs of pembrolizumab were 21% and 71% in patients with or without TERT promoter mutations, respectively (p < 0.001). CONCLUSIONS: Our analysis suggests that the presence of TERT promoter mutations could negatively affect the outcome of UC patients treated by chemotherapy or pembrolizumab. This hypothesis should be further evaluated in wider cohorts.

The 2022 WHO classification of urinary and male genital tumors introduced several novel kidney entities exhibiting eosinophilic/oncocytic features with specific mutational backgrounds. Thus, molecular techniques, such as next-generation sequencing (NGS), became more commonly used for their evaluation. We studied 12 low-grade oncocytic tumors (LOT) of the kidney (from 11 patients), identified in a cohort of 210 eosinophilic/oncocytic renal tumors, diagnosed in our institution between October 2019 and May 2023, which represented 5.7% (12/210) of all eosinophilic/oncocytic renal tumors during this period. We reviewed their clinicopathologic, histologic, and immunohistochemical features, as well as their mutational profiles. We also reviewed the literature on NGS-derived data of LOT, by selecting papers in which LOT diagnosis was rendered according to the criteria proposed initially. Median age was 65 years (mean: 63.5; range 43-79) and median tumor size was 2.0 cm (mean: 2.2; range: 0.9-3.1). All tumors were positive for PAX8, CK7, and GATA3, and negative or focally positive for CD117/KIT. We found the following gene mutations: MTOR ((6/11), 54.5%)), TSC1 ((2/11), 18.2%)), and 1 had both NOTCH1 and NOTCH4 ((1/11), 9.1%)). Wild-type status was found in 2/11 (18.2%) patients and one tumor was not analyzable. A review of 8 previous studies that included 79 LOTs revealed frequent mutations in the genes that regulate the mammalian target of rapamycin (mTOR) pathway: MTOR (32/79 (40.5%)), TSC1 (21/79 (26.6%)), and TSC2 (9/79 (11.4%)). Other mutated genes included PIK3CA, NF2, and PTEN, not typically known to affect the mTOR pathway, but potentially acting as upstream and downstream effectors. Our study shows that LOT is increasingly diagnosed in routine practice when applying the appropriate diagnostic criteria. We also confirm that the mTOR pathway is strongly implicated in the pathogenesis of this tumor mainly through MTOR, TCS1, and TSC2 mutations, but other genes could also be involved in the pathway activation, especially in LOTs without "canonical" mutations.

ECOG performance status (PS) is a pivotal prognostic factor in a wide number of solid tumors. We performed a meta-analysis to assess the role of ECOG PS in terms of survival in patients with ECOG PS 0 or ECOG PS 1 treated with immunotherapy alone or combined with other anticancer treatments. Following the Preferred Reporting Items for Systematic Reviews and Meta-analyses, all phase II and III randomized clinical trials that compared immunotherapy or immune-based combinations in patients with solid tumors were retrieved. The outcomes of interest were overall survival (OS) and progression-free survival (PFS). We also performed subgroup analyses focused on type of therapy (ICI monotherapy or combinations), primary tumor type, setting (first line of treatment, subsequent lines). Overall, 60 studies were included in the analysis for a total of 35.020 patients. The pooled results showed that immunotherapy, either alone or in combination, reduces the risk of death or progression in both ECOG PS 0 and 1 populations. The survival benefit was consistent in all subgroups. Immune checkpoint inhibitors monotherapy or immune-based combinations are associated with improved survival irrespective of ECOG PS 0 or 1. Clinical trials should include more frail patients to assess the value of immunotherapy in these patients.

AIMS: Yolk sac tumour postpubertal-type (YSTpt) shows a wide range of histological patterns and is challenging to diagnose. Recently, forkhead box transcription factor A2 (FoxA2) emerged as a driver of YSTpt formation and a promising marker for diagnosing YSTpt. However, FoxA2 has not been tested in the different patterns of YSTpt. This study aimed to assess the staining pattern of FoxA2 in te different patterns of YSTpt and other germ cell tumours of the testis (GCTT), comparing it with glypican-3 (GPC3) and α-fetoprotein (AFP). METHODS AND RESULTS: FOXA2, GPC3 and AFP immunohistochemistry was performed on 24 YSTpt (24 microcystic/reticular, 10 myxoid, two macrocystic, five glandular/alveolar, two endodermal sinus/perivascular, four solid, two polyembryoma/embryoid body and two polyvesicular vitelline) and 81 other GCTT. The percentage of positive cells (0, 1+, 2+, 3+) and the intensity (0, 1, 2, 3) were evaluated regardless of and within each YSTpt pattern. FoxA2 was positive in all YSTpt (24 of 24) and all but one (23 of 24) exhibited 2+/3+ stain, with higher intensity [median value (mv): 2.6] than AFP (1.8) and GPC3 (2.5). Both FoxA2 and GPC3 were positive in all microcystic/reticular (24 of 24), myxoid (10 of 10), macrocystic (two of two), endodermal sinus/perivascular (four of four) and polyembryoma/embryoid body (two of two) patterns. Nevertheless, only FoxA2 was positive in all glandular/alveolar (five of five), solid (four of four) and polyvesicular vitelline (two of two) patterns. The intensity of FoxA2 was higher than AFP and GPC3 in almost all YST patterns. In the other GCTT, FoxA2 was positive only in teratoma postpubertal-type (Tpt) [13 of 20 (65%)], with staining almost exclusively confined to the mature gastrointestinal/respiratory tract epithelium. CONCLUSIONS: FoxA2 is a highly sensitive and specific biomarker that supports the diagnosis of YSTpt. FoxA2 is superior to GPC3 and AFP, especially in rare and difficult-to-diagnose histological patterns of YSTpt, but mature glands of Tpt could represent a potential diagnostic pitfall.

PURPOSE: Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) revolutionized the therapeutic landscape of non-small-cell lung cancer (NSCLC). However, despite significant survival improvement, the emergence of resistance mechanisms represents a common event. In this meta-analysis, we compared the efficacy and safety of third-generation EGFR-TKIs, the current standard of care, to first-generation EGFR-TKIs with antiangiogenic drugs for the first-line treatment of NSCLC harboring EGFR mutations. MATERIALS AND METHODS: Randomized controlled clinical trials (RCTs) reporting survival data published before September 1, 2022, were searched through the MEDLINE databases (PubMed), the Cochrane Database of Systematic Reviews, and Central Register of Controlled Trials (Wiley). Progression-free survival (PFS), overall survival (OS), objective response rate (ORR), and grade 3 or higher treatment-related adverse events (≥3 TRAEs) data were analyzed. RESULTS: Twelve RCTs were included in our meta-analysis, with a total of 3,565 patients. We observed that third-generation EGFR-TKIs and first-generation EGFR-TKIs combined with antiangiogenic drugs provided a similar OS benefit over first-generation EGFR-TKIs in any of the subgroups. However, we indirectly observed a greater PFS benefit of third-generation EGFR-TKIs over first-generation EGFR-TKIs in females, never-smokers, in patients harboring exon 19 deletions, and in those with brain metastasis, as compared with using first-generation EGFR-TKIs plus antiangiogenic drugs. The ORR did not differ between the combination strategy and third-generation EGFR-TKIs. Finally, the risk of developing grade ≥3 TRAEs was higher using the combination of first-generation EGFR-TKIs and antiangiogenic drugs over first-generation EGFR-TKIs than third-generation EGFR-TKIs over first-generation EGFR-TKIs. CONCLUSION: This meta-analysis suggests that the combination strategy may provide an alternative to third-generation EGFR-TKIs, but more data are needed to determine the predictive clinicopathologic characteristics that can influence the treatment choice. Until then, third-generation EGFR-TKIs still represent the first choice in advanced NSCLC harboring EGFR mutations.

BACKGROUND: In recent years, several studies focused on the process of reprogramming of seminoma (S) cells, which regulates the transition from pure S (P-S) to S component (S-C) of mixed germ cell tumors of the testis (GCTT) and finally to embryonal carcinoma (EC) and other nonseminomatous GCTT (NS-GCTT). The accepted pathogenetic model is driven and regulated by cells (macrophages, B- and T-lymphocytes) and molecules of the tumor microenvironment (TME). Herein, we tested a series of GCTT with double staining (DS) for CD68-PD-L1 to evaluate tumor-associated macrophages (TAMs) expressing programmed death-ligand 1 (PD-L1) [TAMs PD-L1(+)] and clarify if these cells may be involved in establishing the fate of GCTT. METHODS: We collected 45 GCTT (comprising a total of 62 different components of GCTT). TAMs PD-L1(+) were evaluated with three different scoring systems [TAMs PD-L1(+)/mm2, TAMs PD-L1(+)/mm2H-score, TAMs PD-L1(+) %], and compared using pertinent statistic tests (Student's t-test and Mann-Whitney U test). RESULTS: We found that TAMs PD-L1(+) values were higher in S rather than EC (p = 0.001, p = 0.015, p = 0.022) and NS-GCTT (p < 0.001). P-S showed statistically significant differences in TAMs PD-L1(+) values compared to S-C (p < 0.001, p = 0.006, p = 0.015), but there were no differences between S-C and EC (p = 0.107, p = 0.408, p = 0.800). Finally, we found statistically significant differences also in TAMs PD-L1(+) values between EC and other NS-GCTT (p < 0.001). CONCLUSIONS: TAMs PD-L1(+) levels gradually decrease during the reprogramming of S cells {P-S [(high values of TAMs PD-L1(+)] â S-C and EC [(intermediate values of TAMs PD-L1(+)] â other NS-GCTT [(low values of TAMs PD-L1(+)], supporting a complex pathogenetic model where the interactions between tumor cells and TME components [and specifically TAMs PD-L1(+)] play a key role in determining the fate of GCTT.

(1) Background: The oncology field has drastically changed with the advent of precision medicine, led by the discovery of druggable genes or immune targets assessed through next-generation sequencing. Biomarker-based treatments are increasingly emerging, and currently, six tissue-agnostic therapies are FDA-approved. (2) Methods: We performed a review of the literature and reported the trials that led to the approval of tissue-agnostic treatments and ongoing clinical trials currently investigating novel biomarker-based approaches. (3) Results: We discussed the approval of agnostic treatments: pembrolizumab and dostarlimab for MMRd/MSI-H, pembrolizumab for TMB-H, larotrectinib and entrectinib for NTRK-fusions, dabrafenib plus trametinib for BRAF V600E mutation, and selpercatinib for RET fusions. In addition, we reported novel clinical trials of biomarker-based approaches, including ALK, HER2, FGFR, and NRG1. (4) Conclusions: Precision medicine is constantly evolving, and with the improvement of diagnostic tools that allow a wider genomic definition of the tumor, tissue-agnostic targeted therapies are a promising treatment strategy tailored to the specific tumor genomic profile, leading to improved survival outcomes.
RESUMEN
INTRODUCTION: Significant advances have been made in the first-line therapy of metastatic renal cell carcinoma (mRCC) since the approval of immune-based combinations, including nivolumab plus ipilimumab or cabozantinib, and pembrolizumab plus axitinib or lenvatinib. AREAS COVERED: The aim of this review is to compare the different safety profiles of first-line immune-based combinations versus sunitinib across the four respective pivotal trials (CheckMate 214, CheckMate 9ER, KEYNOTE-426, and CLEAR), with a particular attention to patients' health-related quality of life (HRQoL) assessment. EXPERT OPINION: The concurrent use of an immune-checkpoint inhibitor (ICI) with a tyrosine kinase inhibitor (TKI) as a first-line treatment strategy for mRCC has highlighted the unmet clinical need for prompt detection and consequently proper management of adverse events (AEs), both immune-related and TKI-induced. Overlapping AEs, such as hypertransaminasemia, are most challenging to manage, and evidence is still outlined from clinical practice. The specific patterns of toxicities of the approved first-line immune-based combinations, along with the impact of these interventions on patients' HRQoL, demand a deeper consideration by physicians while choosing the appropriate treatment for each individual mRCC patient. Both safety profile and HRQoL evaluation could be exploited to guide the first-line treatment selection in this setting.

BACKGROUND: The antitumor efficacy of immune checkpoint inhibitors (ICIs) has increasingly emerged during the last few years. However, there is a need to identify the safety profile of these agents more comprehensively, including liver toxicity. MATERIALS AND METHODS: Herein, we performed a meta-analysis to assess the risk of all-grade and grade 3-4 hypertransaminasemia in cancer patients receiving ICIs-as monotherapy or in combination with other anticancer agents. All the relevant trials were retrieved through EMBASE, Cochrane Library, and PubMed/Medline databases; eligible studies were selected according to PRISMA statement. The pooled relative risk (RR) and 95% confidence interval (CI) were extracted. RESULTS: Fifty-nine studies were included. The pooled RRs for all-grade AST and ALT increase were 1.45 (95% CI 1.26-1.67) (Supplementary Fig. 3) and 1.51 (95% CI 1.29-1.77) in patients receiving ICIs monotherapy and immune-based combinations compared to control treatment, respectively. The pooled RRs for grade 3-4 AST and ALT increase were 2.16 (95% CI 1.77-2.64) and 2.3 (95% CI 1.91-2.77). CONCLUSIONS: According to our results, ICIs monotherapy and immune-based combinations were associated with higher risk of all-grade and grade 3-4 hypertransaminasemia. Monitoring liver function should be recommended in cancer patients treated with ICIs monotherapy or immune-based combination, and in case of underlying liver disease, a careful risk-benefit assessment appears as a mandatory need.

PURPOSE: The aim is to clarify the use of perioperative chemotherapy in resectable goblet cell carcinoma (GCC). METHODS: A retrospective study was carried out based on the Surveillance, Epidemiology, and End Results study. The population was divided: into patients who received only radical surgery (group A) and those who received radical surgery plus chemotherapy (group B). An entropy balancing was carried out to correct the imbalance between the two groups. Two models were generated. Model 1 contained only high-risk patients: group B and a "virtual" group A with similar characteristics. Model 2 included only low-risk patients: group A and "virtual" group B with identical attributes. The efficacy of entropy balancing was evaluated with the d value. The overall survival was compared and reported with Hazard Ratio (HR) within a confidence interval of 95% (95 CI). RESULTS: The groups A and B were imbalanced for tumor size (d = 0.392), T (d = 1.128), N (d = 1.340), M (d = 1.456), mean number of positive lymph nodes (d = 0.907), and LNR (d = 0.889). Before the balancing, the risk of death was higher in group B than in A (4.3; 2.5 to 7.4). After reweighting, all large differences were eliminated (d < 0.200). In high-risk patients, the risk of death was higher in patients who underwent surgery alone than those who received perioperative chemotherapy (HR 0.5; 0.2 to 1.3) without statistical significance (p = 0.187). In low-risk patients, the risk of death was similar (HR 1.1; 0.3 to 3.3). CONCLUSION: Perioperative chemotherapy could provide some marginal advantages to high-risk patients.

Pancreatic cancer (PC) is a recalcitrant disease characterized by high incidence and poor prognosis. The extremely complex genomic landscape of PC has a deep influence on cultivating a tumor microenvironment, resulting in the promotion of tumor growth, drug resistance, and immune escape mechanisms. Despite outstanding progress in personalized medicine achieved for many types of cancer, chemotherapy still represents the mainstay of treatment for PC. Olaparib was the first agent to demonstrate a significant benefit in a biomarker-selected population, opening the doors for a personalized approach. Despite the failure of a large number of studies testing targeted agents or immunotherapy to demonstrate benefits over standard chemotherapy regimens, some interesting agents, alone or in combination with other drugs, have achieved promising results. A wide spectrum of therapeutic strategies, including immune-checkpoint inhibitors tyrosine kinase inhibitors and agents targeting metabolic pathways or the tumor microenvironment, is currently under investigation. In this review, we aim to provide a comprehensive overview of the current landscape and future directions of personalized medicine for patients affected by PC.
RESUMEN
Thymic tumors are a group of rare mediastinal malignancies that include three different histological subtypes with completely different clinical behavior: the thymic carcinomas, the thymomas, and the rarest thymic neuroendocrine tumors. Nowadays, few therapeutic options are available for relapsed and refractory thymic tumors after a first-line platinum-based chemotherapy. In the last years, the deepening of knowledge on thymus' biological characterization has opened possibilities for new treatment options. Several clinical trials have been conducted, the majority with disappointing results mainly due to inaccurate patient selection, but recently some encouraging results have been presented. In this review, we summarize the molecular alterations observed in thymic tumors, underlying the great biological differences among the different histology, and the promising targeted therapies for the future.
