  • Complete locoregional response to radiotherapy and pembrolizumab in an elderly and frail patient with oropharyngeal squamous cell carcinoma: A case report

    Medicine United States, 2026
    Rationale: Immune checkpoint inhibitors (ICIs) have revolutionized the management of head and neck squamous cell carcinoma, particularly in the recurrent/metastatic setting. Although the combination of ICIs and radiotherapy (RT) in locally advanced disease has not yet demonstrated clear survival benefits, the strong biological rationale for their synergistic action continues to support investigation, especially in frail or elderly patients unfit for standard chemoradiotherapy. Patient concerns: An 83-year-old male presented with odynophagia, dysphagia, significant weight loss, and right cervical swelling, all impairing oral intake and quality of life. Diagnoses: Moderately differentiated squamous cell carcinoma (G2) of the oropharynx (right base of tongue), human papillomavirus-negative, programmed death-ligand 1 combined positive score = 30. The tumor was staged as cT4a cN3b M1. Interventions: The patient underwent hypofractionated RT (50 Gy in 20 fractions) delivering only to the primary lesion, followed by pembrolizumab 200 mg every 3 weeks. One pulmonary oligoprogressive lesion was treated with stereotactic body RT (60 Gy in 8 fractions). After 29 cycles of pembrolizumab, treatment was discontinued due to the onset of immune-related grade 3 hepatotoxicity. Two additional pulmonary oligoprogressive lesions were treated with stereotactic body radiotherapy, 55 Gy in 5 fractions. Outcomes: A complete response was achieved and maintained at both the primary tumor and nodal sites. Following immunotherapy discontinuation, liver biopsy confirmed immune-related cholangitis. Despite persistent elevation of cholestatic markers, disease control on T and N was preserved. A new pulmonary oligoprogression is currently under active surveillance. Lessons: This case supports the hypothesis of synergism between RT and immunotherapy in an elderly and frail patient with advanced head and neck squamous cell carcinoma. Hypofractionated RT on the primary tumor alone, combined with ICIs, may lead to sustained locoregional control. Immune-related hepatic toxicity, while clinically significant, did not preclude stable disease.
  • Carboplatin, etoposide, atezolizumab, and bevacizumab in the first-line treatment of patients with extensive stage small-cell lung cancer: the GOIRC-01-2019 CeLEBrATE study

    Journal for Immunotherapy of Cancer, 2025
    BackgroundThe addition of a programmed death-ligand 1 (PD-L1) inhibitor, either atezolizumab or durvalumab, to platinum-etoposide prolonged survival in a limited subset of patients with extensive-stage small-cell lung cancer (ES-SCLC). Preclinical studies demonstrated synergistic antitumor activity of combined vascular endothelial growth factor receptor and PD-L1 inhibition in SCLC. Since bevacizumab added to platinum-etoposide was safe and active in ES-SCLC, we investigated the efficacy of atezolizumab, bevacizumab, carboplatin, and etoposide as first-line treatment of ES-SCLC.MethodsThe CeLEBrATE study is an Italian multicentric single-arm phase II trial of carboplatin (area under the curve 5 ml/min), etoposide (100 mg/sqm), bevacizumab (7.5 mg/kg), and atezolizumab (1,200 mg) every 3 weeks (q3w) for four to six courses, followed by bevacizumab and atezolizumab maintenance q3w in patients with ES-SCLC and no contraindications to immunotherapy or antiangiogenic therapy. Patients with asymptomatic brain metastases were eligible. Prophylactic cranial irradiation and consolidation thoracic external radiotherapy were not permitted while on study treatment. Primary endpoint was overall survival (OS) rate at 1 year.Results53 patients were enrolled (45.3% women, median age 65 years) and received at least one dose of study treatment. At a median follow-up time of 23.4 months (95% CI: 21.1 to 26.0), the 1-year OS rate was 61.8% (90% CI: 50.7% to 72.8%; p=0.04), with a median OS of 12.9 months (95% CI: 11.6 to 17.5). Median progression-free survival was 6.2 months (95% CI: 5.4 to 6.6) and objective response rate was 83.3% (95% CI: 69.8% to 92.5%). Grade 3–4 adverse events were reported in 34 patients (64.2%) leading to dose reductions in 24 (45.3%), and dose delays in 39 (73.9%) and 32 (69.6%) during the induction and maintenance phase, respectively. 19 (35.8%) treatment-related serious adverse events were reported.ConclusionThe CeLEBrATE study met its primary objective demonstrating a signal of efficacy of bevacizumab, atezolizumab, carboplatin, and etoposide in the first-line treatment of patients with ES-SCLC.Trial registration numberGOIRC-01–2019 ML41241, Eudract Number: 2019-003798-2.

    Cancer Immunology Immunotherapy, 2024
    Background Immune checkpoint inhibitors (ICIs) are standard treatments for advanced solid cancers. Resistance to ICIs, both primary and secondary, poses challenges, with early mortality (EM) within 30–90 days indicating a lack of benefit. Prognostic factors for EM, including the lung immune prognostic index (LIPI), remain underexplored. Methods We performed a retrospective, observational study including patients affected by advanced solid tumors, treated with ICI as single agent or combined with other agents. Logistic regression models identified factors associated with EM and 90-day progression risks. A nomogram for predicting 90-day mortality was built and validated within an external cohort. Results In total, 637 patients received ICIs (single agent or in combination with other drugs) for advanced solid tumors. Most patients were male (61.9%), with NSCLC as the prevalent tumor (61.8%). Within the cohort, 21.3% died within 90 days, 8.4% died within 30 days, and 34.5% experienced early progression. Factors independently associated with 90-day mortality included ECOG PS 2 and a high/intermediate LIPI score. For 30-day mortality, lung metastasis and a high/intermediate LIPI score were independent risk factors. Regarding early progression, high/intermediate LIPI score was independently associated. A predictive nomogram for 90-day mortality combining LIPI and ECOG PS achieved an AUC of 0.76 (95% CI 0.71–0.81). The discrimination ability of the nomogram was confirmed in the external validation cohort (n = 255) (AUC 0.72, 95% CI 0.64–0.80). Conclusion LIPI and ECOG PS independently were able to estimate 90-day mortality, with LIPI also demonstrating prognostic validity for 30-day mortality and early progression.

    Patients with cancer of unknown primary (CUP) carry the double burden of an aggressive disease and reduced access to therapies. Experimental models are pivotal for CUP biology investigation and drug testing. We derived two CUP cell lines (CUP#55 and #96) and corresponding patient-derived xenografts (PDXs), from ascites tumor cells. CUP cell lines and PDXs underwent histological, immune-phenotypical, molecular, and genomic characterization confirming the features of the original tumor. The tissue-of-origin prediction was obtained from the tumor microRNA expression profile and confirmed by single-cell transcriptomics. Genomic testing and fluorescence in situ hybridization analysis identified FGFR2 gene amplification in both models, in the form of homogeneously staining region (HSR) in CUP#55 and double minutes in CUP#96. FGFR2 was recognized as the main oncogenic driver and therapeutic target. FGFR2-targeting drug BGJ398 (infigratinib) in combination with the MEK inhibitor trametinib proved to be synergic and exceptionally active, both in vitro and in vivo. The effects of the combined treatment by single-cell gene expression analysis revealed a remarkable plasticity of tumor cells and the greater sensitivity of cells with epithelial phenotype. This study brings personalized therapy closer to CUP patients and provides the rationale for FGFR2 and MEK targeting in metastatic tumors with FGFR2 pathway activation.

    Journal of Experimental and Clinical Cancer Research, 2022
    Background In the last years, several efforts have been made to classify colorectal cancer (CRC) into well-defined molecular subgroups, representing the intrinsic inter-patient heterogeneity, known as Consensus Molecular Subtypes (CMSs). Methods In this work, we performed a meta-analysis of CRC patients stratified into four CMSs. We identified a negative correlation between a high level of anaplastic lymphoma kinase (ALK) expression and relapse-free survival, exclusively in CMS1 subtype. Stemming from this observation, we tested cell lines, patient-derived organoids and mice with potent ALK inhibitors, already approved for clinical use. Results ALK interception strongly inhibits cell proliferation already at nanomolar doses, specifically in CMS1 cell lines, while no effect was found in CMS2/3/4 groups. Furthermore, in vivo imaging identified a role for ALK in the dynamic formation of 3D tumor spheroids. Consistently, ALK appeares constitutively phosphorylated in CMS1, and it signals mainly through the AKT axis. Mechanistically, we found that CMS1 cells display several copies of ALKAL2 ligand and ALK-mRNAs, suggesting an autocrine loop mediated by ALKAL2 in the activation of ALK pathway, responsible for the invasive phenotype. Consequently, disruption of ALK axis mediates the pro-apoptotic action of CMS1 cell lines, both in 2D and 3D and enhanced cell-cell adhesion and e-cadherin organization. In agreement with all these findings, the ALK signature encompassing 65 genes statistically associated with worse relapse-free survival in CMS1 subtype. Finally, as a proof of concept, the efficacy of ALK inhibition was demonstrated in both patient-derived organoids and in tumor xenografts in vivo. Conclusions Collectively, these findings suggest that ALK targeting may represent an attractive therapy for CRC, and CMS classification may provide a useful tool to identify patients who could benefit from this treatment. These findings offer rationale and pharmacological strategies for the treatment of CMS1 CRC.
  • Unexpected response to fourth-line paclitaxel in a patient with metastatic oropharyngeal squamous cell carcinoma, immunotherapy-refractory: a case report
    Mirta Mosca, Daria Maria Filippini, Nastassja Tober, Fabiola Lorena Rojas, Karim Rihawi, Francesca Di Fabio
    Anti Cancer Drugs, 2022
    In recent years, immune checkpoint inhibitors (ICIs), including nivolumab and pembrolizumab have revolutionized the treatment landscape in recurrent/metastatic (R/M) head and neck squamous cell carcinoma (HNSCC). However, many patients do not respond to ICIs for reasons that remain largely unknown. For patients who progress on ICIs, chemotherapy and/or biologic therapies are the most widely used treatments based on the clinician’s choice, with no defined sequence strategy. We report the experience of a patient with metastatic oropharyngeal squamous cell cancer p16 and human papillomavirus-DNA positive who received chemotherapy with weekly paclitaxel after progressing on nivolumab. Our patient presented a partial response to fourth line paclitaxel, which lasted more than 2 years, with an improvement of his quality of life too. These results support the hypothesis of synergism between immunotherapy and conventional chemotherapies. Even in the setting of immune-refractory disease, immunotherapy may affect tumor immune microenvironment thus leading to a synergistic effect with conventional chemotherapy and achieving unexpected results.

    •Encorafenib plus cetuximab ± binimetinib is safe and effective for BRAF V600E mut mCRC even in the real-world setting.•Median OS is slightly shorter than in the BEACON trial, probably due to less selected patients in real life.•Patients deriving more benefit from targeted therapy are likely those in good general conditions and not heavily pretreated.•BRAF adjusted MAF is worth further investigation to better characterize the genomic heterogeneity of BRAF V600E mut mCRC. BackgroundEncorafenib plus cetuximab with or without binimetinib showed increased objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) compared with chemotherapy plus anti-EGFR in previously treated patients with BRAF V600E-mutated (mut) metastatic colorectal cancer (mCRC). Although no formal comparison was planned, addition of binimetinib to encorafenib plus cetuximab did not provide significant efficacy advantage.Patients and methodsThis real-life study was aimed at evaluating safety, activity, and efficacy of encorafenib plus cetuximab with or without binimetinib in patients with BRAF V600E-mut mCRC treated at 21 Italian centers within a nominal use program launched in May 2019.ResultsOut of 133 patients included, 97 (73%) received encorafenib plus cetuximab (targeted doublet) and 36 (27%) the same therapy plus binimetinib (targeted triplet). Most patients had Eastern Cooperative Group Performance Status (ECOG-PS) of 0 or 1 (86%), right-sided primary tumor (69%), and synchronous disease (66%). Twenty (15%) tumors were DNA mismatch repair deficiency (dMMR)/microsatellite instability (MSI)-high. As many as 44 (34%) patients had received two or more prior lines of therapy, 122 (92%) were previously exposed to oxaliplatin, and 109 (82%) to anti-vascular endothelial growth factor (anti-VEGF). Most frequent adverse events were asthenia (62%) and anti-EGFR-related skin rash (52%). Any grade nausea (P = 0.03), vomiting (P = 0.04), and diarrhea (P = 0.07) were more frequent with the triplet therapy, while melanocytic nevi were less common (P = 0.06). Overall, ORR and disease control rate (DCR) were 23% and 69%, respectively, with numerically higher rates in the triplet group (ORR 31% versus 17%, P = 0.12; DCR 78% versus 65%, P = 0.23). Median PFS and OS were 4.5 and 7.2 months, respectively. Worse ECOG-PS, peritoneal metastases, and more than one prior treatment were independent poor prognostic factors for PFS and OS. Clonality of BRAF mutation measured as adjusted mutant allele fraction in tumor tissue was not associated with clinical outcome.ConclusionsOur real-life data are consistent with those from the BEACON trial in terms of safety, activity, and efficacy.

    Cancers, 2022
    Background: Rectal cancer is a malignant neoplasm of the large intestine resulting from the uncontrolled proliferation of the rectal tract. Predicting the pathologic response of neoadjuvant chemoradiotherapy at an MRI primary staging scan in patients affected by locally advanced rectal cancer (LARC) could lead to significant improvement in the survival and quality of life of the patients. In this study, the possibility of automatizing this estimation from a primary staging MRI scan, using a fully automated artificial intelligence-based model for the segmentation and consequent characterization of the tumor areas using radiomic features was evaluated. The TRG score was used to evaluate the clinical outcome. Methods: Forty-three patients under treatment in the IRCCS Sant’Orsola-Malpighi Polyclinic were retrospectively selected for the study; a U-Net model was trained for the automated segmentation of the tumor areas; the radiomic features were collected and used to predict the tumor regression grade (TRG) score. Results: The segmentation of tumor areas outperformed the state-of-the-art results in terms of the Dice score coefficient or was comparable to them but with the advantage of considering mucinous cases. Analysis of the radiomic features extracted from the lesion areas allowed us to predict the TRG score, with the results agreeing with the state-of-the-art results. Conclusions: The results obtained regarding TRG prediction using the proposed fully automated pipeline prove its possible usage as a viable decision support system for radiologists in clinical practice.
  • A phase II, open-label, single-arm trial of carboplatin plus etoposide with bevacizumab and atezolizumab in patients with extended-stage small-cell lung cancer (CeLEBrATE study): Background, design and rationale

    Future Oncology, 2022
    Based on improved survival from the addition of PD-L1 inhibitors in phase III trials, the combination of immunotherapy and platinum-doublet chemotherapy has become the new standard treatment for extended-stage small-cell lung cancer (ES-SCLC). Furthermore, the antiangiogenetic agent bevacizumab showed a longer progression-free survival by targeting VEGF that has pleiotropic effects, including immunosuppressive ones. We, therefore, hypothesized that targeting angiogenesis would improve the efficacy of chemoimmunotherapy. The CeLEBrATE trial is an open-label, multicenter, phase II study designed to assess the efficacy and safety of the combination of carboplatin and etoposide plus bevacizumab and atezolizumab in treatment-naive patients with ES-SCLC. The primary end point is overall survival rate at 1 year, while secondary end points include overall response rate, progression-free survival and toxicity.
  • Pneumatosis intestinalis and spontaneous perforation associated with drug toxicity in oncologic patients: A case series

    Acta Gastro Enterologica Belgica, 2021
    Pneumatosis Intestinalis (PI) is a rare radiological finding defined as the presence of extra-luminal gas within the intestinal wall. Several anti-tumor drugs can induce a damage of the gastrointestinal walls as an adverse effect, causing loss of mucosal integrity and endoluminal gas diffusion, responsible for PI development. We retrospectively analyzed 8 cases of PI detected through radiological imaging in oncologic patients undergoing various therapeutic regimens: five patients were receiving chemotherapy, two molecular targeted therapy (MTT) and one immunotherapy. Three patients were asymptomatic and pneumatosis was incidentally detected at routinary follow-up CT and then treated conservatively. Five patients presented acute abdomen symptoms and in these cases bowel perforation was the cause of death. Our experience confirms PI and perforation as rare complications of drug toxicity, especially in oncologic patients treated with combinations of different anticancer drugs and documented the second reported case of PI associated with atezolizumab and alectinib single administration.
