RESUMO
The Stupp regimen remains the standard treatment for newly diagnosed glioblastomas, although the prognosis remains poor. Several temozolomide alternative schedules have been studied, with extended adjuvant treatment (>6 cycles of temozolomide) frequently used, although different trials have indicated contrasting results. Survival data of 87 patients who received 6 ('6C' group) or 12 ('12C' group) cycles of temozolomide were collected between 2012 and 2022. A total of 45 patients were included in the 6C group and 42 patients were included in the 12C group. Data on isocitrate dehydrogenase mutation and methylguanine-DNA-methyltransferase (MGMT) promoter methylation status were also collected. The 12C group exhibited statistically significantly improved overall survival [OS; 22.8 vs. 17.5 months; hazard ratio (HR), 0.47; 95% CI, 0.30-0.73; P=0.001] and progression-free survival (15.3 vs. 9 months; HR, 0.39; 95% CI, 0.25-0.62; P=0.001). However, in the subgroup analysis according to MGMT status, OS in the 12C group was significantly superior to OS in the 6C group only in the MGMT unmethylated tumors. The present data suggested that extended adjuvant temozolomide appeared to be more effective than the conventional six cycles.
RESUMO
Colorectal cancer (CRC) is the third most commonly diagnosed cancer worldwide, with 20% of patients presenting with metastatic disease at diagnosis. TGF-ß signaling plays a crucial role in various cellular processes, including growth, differentiation, apoptosis, epithelial-mesenchymal transition (EMT), regulation of the extracellular matrix, angiogenesis, and immune responses. TGF-ß signals through SMAD proteins, which are intracellular molecules that transmit TGF-ß signals from the cell membrane to the nucleus. Alterations in the TGF-ß pathway and mutations in SMAD proteins are common in metastatic CRC (mCRC), making them critical factors in CRC tumorigenesis. This review first analyzes normal TGF-ß signaling and then investigates its role in CRC pathogenesis, highlighting the mechanisms through which TGF-ß influences metastasis development. TGF-ß promotes neoangiogenesis via VEGF overexpression, pericyte differentiation, and other mechanisms. Additionally, TGF-ß affects various elements of the tumor microenvironment, including T cells, fibroblasts, and macrophages, promoting immunosuppression and metastasis. Given its strategic role in multiple processes, we explored different strategies to target TGF-ß in mCRC patients, aiming to identify new therapeutic options.

BACKGROUND: The growing understanding of cancer biology and the establishment of new treatment modalities has not yielded the expected results in terms of survival for Laryngeal Squamous Cell Cancer (LSCC). Early diagnosis, as well as prompt identification of patients with high risk of relapse would ensure greater chance of therapeutic success. However, this goal remains a challenge due to the absence of specific biomarkers for this neoplasm. METHODS: Serum samples from 45 LSCC patients and 23 healthy donors were collected for miRNA expression profiling by TaqMan Array analysis. Additional 20 patients and 42 healthy volunteers were included for the validation set, reaching an equal number of clinical samples for each group. The potential diagnostic ability of the such identified three-miRNA signature was confirmed by ROC analysis. Moreover, each miRNA was analyzed for the possible correlation with HNSCC patients' survival and TNM status by online databases Kaplan-Meier (KM) plotter and OncomiR. In silico analysis of common candidate targets and their network relevance to predict shared biological functions was finally performed by PANTHER and GeneMANIA software. RESULTS: We characterized serum miRNA profile of LSCC patients identifying a novel molecular signature, including miR-223, miR-93 and miR-532, as circulating marker endowed with high selectivity and specificity. The oncogenic effect and the prognostic significance of each miRNA was investigated by bioinformatic analysis, denoting significant correlation with OS. To analyse the molecular basis underlying the pro-tumorigenic role of the signature, we focused on the simultaneously regulated gene targets-IL6ST, GTDC1, MAP1B, CPEB3, PRKACB, NFIB, PURB, ATP2B1, ZNF148, PSD3, TBC1D15, PURA, KLF12-found by prediction tools and deepened for their functional role by pathway enrichment analysis. The results showed the involvement of 7 different biological processes, among which inflammation, proliferation, migration, apoptosis and angiogenesis. CONCLUSIONS: In conclusion, we have identified a possible miRNA signature for early LSCC diagnosis and we assumed that miR-93, miR-223 and miR-532 could orchestrate the regulation of multiple cancer-related processes. These findings encourage the possibility to deepen the molecular mechanisms underlying their oncogenic role, for the desirable development of novel therapeutic opportunities based on the use of short single-stranded oligonucleotides acting as non-coding RNA antagonists in cancer.

Salivary gland carcinomas (SGCs) are rare neoplasms, representing less than 10% of all head and neck tumors, but they are extremely heterogeneous from the histological point of view, their clinical behavior, and their genetics. The guidelines regarding their treatment include surgery in most cases, which can also play an important role in oligometastatic disease. Where surgery cannot be used, systemic therapy comes into play. Systemic therapy for many years has been represented by polychemotherapy, but recently, with the affirmation of translational research, it can also count on targeted therapy, at least in some subtypes of SGCs. Interestingly, in some SGC histotypes, predominant mutations have been identified, which in some cases behave as "driver mutations", namely mutations capable of governing the carcinogenesis process. Targeting these driver mutations may be an effective therapeutic strategy. Nonetheless, it is not always possible to have drugs suitable for targeting driver mutations-and targeting driver mutations is not always accompanied by a clinical benefit. In this review, we will analyze the main mutations predominant in the various histotypes of SGCs.
RESUMO
INTRODUCTION: Benign tracheobronchial stenosis is a abnormal tracheal lumen narrowing that may incur progressive dyspnea and life-threatening hypoxemia. There is no consensus on which patients should be treated with endoscopic or surgical method. This study investigates the outcomes of bronchoscopic dilatation in the treatment of benign tracheal stenosis using a device equipped with a blade to cut the stenotic lesions with dense fibrosis. MATERIALS AND METHODS: The procedure was carried out in an operating room under general anesthesia. All patients were intubated with a Rigid Bronchoscope (RB) placed just above the stenosis. Through Rigid Bronchoscopy combined modalities were used as needed: radial incisions of the mucosal stenosis with blade at the levels of 4, 8 and 12 o'clock, with back and forth movements, then the stenotic area was dilated more easily with a rigid bronchoscope. Dilatation was performed by passing the RB of increasing diameter through stenotic areas and then Balloon dilatation of increasing diameter. There were no complications during the procedure. RESULT: We conducted an observational, retrospective, single-centre study in the Thoracic Surgery Unit of the University of 'Luigi Vanvitelli' of Naples from November 2011 to September 2021. We included all consecutive patients with benign tracheal stenosis inoperable. During the study period, 113 patients were referred to our department with benign tracheal stenosis inoperable. 61 patients were treated with the blade. During the follow-up, a recurrence of the stenosis was observed in 8 patients in the first month and in 4 patients in the third month. Instead in the patients treated with the use of laser (52 patients), during the follow-up a recurrence was observed in 16 patients in the first month and in 6 patients in the third month; no patient relapsed after 6 months and after 1 year. Long term successful bronchoscopic management with blade was attained by 99% in simple and 93% in mixed stenosis and in complex type stenosis. CONCLUSION: Our study underlines the importance of the use of the blade in bronchoscopic treatment as a valid conservative approach in the management of patients with inoperable benign tracheal stenosis as an alternative to the use of the laser, reducing the abnormal inflammatory reaction in order to limit recurrences.

PURPOSE: Our purposes were: 1) to estimate the prediction performance (PP) of cytology in identifying papillary thyroid carcinoma (PTC) subtypes; 2) to explore how the PTC subtypes distribute among the American College of Radiology (ACR) Thyroid Imaging Reporting and Data System (TI-RADS) categories. METHODS: Nodules were included if both the histology with the PTC subtype report and the cytology report with the possible PTC subtype were available. The PP was calculated by making the proportion of True positives/False positives+false negatives. RESULTS: 309 cytologically "suspicious for malignancy" and "malignant" thyroid nodules with PTC histology were evaluated. ACR TI-RADS categorization for classical PTC was significantly different from non-classical PTC (p-value 0.02). For the whole cohort the PP of cytologically classical cases was 0.74, while that of cytologically non classical cases was 0.41. ACR TI-RADS categorization was not significantly different for aggressive vs non-aggressive PTC subtypes (p-value 0.1). When considering only aggressive or non-aggressive PTC subtypes, the PP of cytologically classical cases was respectively 0.86 and 0.87, while that of cytologically non classical cases was respectively 0.27 and 0.22. The PP of cytologically classical cases was 0.73 and 0.79, respectively for macroPTCs and microPTCs, while that of cytologically non classical cases was 0.55 and 0.33, respectively for macroPTCs and microPTCs. CONCLUSION: Cytology examination reliably performed in predicting classical PTC versus non classical PTC subtypes. ACR TI-RADS categorization was significantly different among classical PTC versus non classical PTC subtypes.
RESUMO
BACKGROUND: Video-assisted thoracoscopic surgery (VATS) resection of deep-seated lung nodules smaller than 1 cm is extremely challenging. Several methods have been proposed to overcome this limitation but with not neglectable complications. Intraoperative lung ultrasound (ILU) is the latest minimally invasive proposed technique. The aim of the current study was to analyze the accuracy and efficacy of ILU associated with VATS to visualize solitary and deep-seated pulmonary nodules smaller than 1 cm. METHODS: Patients with subcentimetric solitary and deep-seated pulmonary nodules were included in this retrospective study from November 2020 to December 2022. Patients who received VATS aided with ILU were considered as group A and patients who received conventional VATS as group B (control group). The rate of nodule identification and the time for localization with VATS alone and with VATS aided with ILU in each group were analyzed. RESULTS: A total of 43 patients received VATS aided with ILU (group A) and 31 patients received conventional VATS (group B). Mean operative time was lower in group A (p < 0.05). In group A all the nodules were correctly identified, while in group B in one case the localization failed. The time to identify the lesion was lower in group A (7.1 ± 2.2 vs. 13.8 ± 4.6; p < 0.05). During hospitalization three patients (6.5%; p < 0.05) in group B presented air leaks that were conservatively managed. CONCLUSION: Intracavitary VATS-US is a reliable, feasible, real-time and effective method of localization of parenchymal lung nodules during selected wedge resection procedures.

BACKGROUND: The NAPOLI-I trial showed better outcome of nanoliposomal irinotecan (nal-IRI) plus 5-fluorouracil/leucovorin (5-FU/LV) compared to 5-FU/LV in patients with advanced pancreatic ductal adenocarcinoma cancer (advPDAC) progressed to gemcitabine-based therapy. This study aims to explore the real-world efficacy and safety of 5-FU/LV-nal-IRI. METHODS: This is a retrospective multicenter analysis including advPDAC patients receiving 5-FU/LV-nal-IRI after failure of gemcitabine-based therapy. Survival analyses were performed using Kaplan-Meier method, univariate and multivariate analyses by Cox regression. RESULTS: A total of 296 patients (median age 64.4 years, ECOG PS ≥1 in 56% of cases) were treated at 11 Italian institutions between 2016 and 2018. 34% of them underwent primary tumor resection, and 79% received gemcitabine-nabpaclitaxel as first line. 5-FU/LV-nal-IRI was administered as second-line in 73% of cases. Objective response and disease control rate were 12% and 41%, respectively. Treatment was well tolerated with dose reductions in 50% of patients but no one permanent discontinuation; the commonest grade ≥3 toxicities were neutropenia (14%) and diarrhea (12%). Median PFS and OS from 5-FU/LV-nal-IRI initiation was 3.2 and 7.1 months, respectively. CONCLUSIONS: These real-world data confirm the 5-FU/LV-nal-IRI efficacy and safety in advPDAC patients progressed to gemcitabine-based therapy, with outcomes comparable to NAPOLI-1, even in a less-selected population and with more modern therapeutic algorithm.

BACKGROUND: Persistent air leak (PAL) is a common complication after video-assisted thoracoscopic surgery (VATS) lobectomy. We aimed to evaluate whether the intraoperative quantitative measurement of air leaks using a mechanical ventilation test could predict PAL and identify those patients needing additional treatment for the prevention of PAL. METHODS: This was an observational, retrospective, single-center study that included 82 patients who underwent VATS lobectomy with a mechanical ventilation test for VL. Only 2% of patients who underwent lobectomy surgery had persistent air leaks. RESULTS: At the end of lobectomy performed in patients with non-small cell lung cancer, the lung was reinflated at a 25-30 mmH2O pressure and ventilatory leaks (VL) were calculated and in relation to the entity of the air leaks, we evaluated the most suitable intraoperative treatment to prevent persistent air leaks. CONCLUSION: VL is an independent predictor of PAL after VATS lobectomy; it provides a real-time intraoperative guidance to identify those patients who can benefit from additional intraoperative preventive interventions to reduce PAL.

Background: Solitary fibrous tumor (SFT) is a rare mesenchymal neoplasm, generally arising in the visceral pleura. It rarely originates from other sites such as trachea, orbital cavities, nasal cavities, peritoneum, paranasal sinuses, meninges, salivary glands, thyroid gland, diaphragm, liver, pancreas, lung kidney, adrenal gland, mediastinum, spermatid cord, pericardium, urinary bladder, prostate, uterine cervix, testis, spinal cord, periosteum, skin, soft tissue and bone. Case Description: We present a surgical case of a rare primary tracheal tumor. High resolution computed tomography (HRCT) scan of the chest showed a 5 mm hypodense lesion, located on the right lateral wall of the proximal third of trachea; however the tracheal lumen was normal. We performed a rigid bronchoscopy in order to remove the endotracheal tumor with palliative purposes only. For this reason, we did not perform a prior histologic examination. The lesion was easily removed with common biopsy forceps and with standard aspirator. The debulking of the tumor was achieved with the use of laser Nd-YAP, electrocautery was used also for hemostasis to prevent bleeding during the operation. Without complications during the endoscopic treatment, the procedure was well tolerated by the patient. The pathological diagnosis was SFT. Conclusions: SFT located in the trachea can be endoscopically resceted. Endoscolical treatment is indicated for patients with poor clinical conditions (heart disease, respiratory failure) that are not elegible for surgical resection.
RESUMO
Chemical, physical, and infectious agents may induce carcinogenesis, and in the latter case, viruses are involved in most cases. The occurrence of virus-induced carcinogenesis is a complex process caused by an interaction across multiple genes, mainly depending by the type of the virus. Molecular mechanisms at the basis of viral carcinogenesis, mainly suggest the involvement of a dysregulation of the cell cycle. Among the virus-inducing carcinogenesis, Epstein Barr Virus (EBV) plays a major role in the development of both hematological and oncological malignancies and importantly, several lines of evidence demonstrated that nasopharyngeal carcinoma (NPC) is consistently associated with EBV infection. Cancerogenesis in NPC may be induced by the activation of different EBV "oncoproteins" which are produced during the so called "latency phase" of EBV in the host cells. Moreover, EBV presence in NPC does affect the tumor microenvironment (TME) leading to a strongly immunosuppressed status. Translational implications of the above-mentioned statements are that EBV-infected NPC cells can express proteins potentially recognized by immune cells in order to elicit a host immune response (tumor associated antigens). Three immunotherapeutic approaches have been implemented for the treatment of NPC including active, adoptive immunotherapy, and modulation of immune regulatory molecules by use of the so-called checkpoint inhibitors. In this review, we will highlight the role of EBV infection in NPC development and analyze its possible implications on therapy strategies.
RESUMO
Glioblastoma multiforme is one of the most frequent and aggressive primary tumors in the central nervous system, representing >60% of all brain tumors in adults. Despite treatment, prognosis remains poor with most if not all patients experiencing disease recurrence and a 2-year survival rate of 27%. At present, no confirmed standard treatment exists for recurrent glioblastoma. Regorafenib is one of the few options available, based on results from the REGOMA trial. In the present study, a real-life retrospective investigation on the role of regorafenib in patients with recurrent glioblastoma (>60 years old) from two main Oncological Units in South Italy (Azienda Ospedaliera Universitaria Luigi Vanvitelli, Naples, Italy and Ospedale Civile San Giovanni di Dio, Frattamaggiore, Naples, Italy), was performed. The primary endpoint was overall survival (OS), whereas progression-free survival (PFS), objective response rate and disease control were secondary endpoints. Survival was then analyzed according to age, isocitrate dehydrogenase (IDH) and methylated methylguanine-DNA-methyltransferase (MGMT) status. A total of 56 patients met the eligibility criteria. The intention to treat population median PFS (mPFS) was 4.1 months and median OS (mOS) was 6.8 months. Age did not appear to have a significant influence on mPFS. mOS in MGMT-methylated patients was improved compared with that of the unmethylated group (7.7 months vs. 5.6 months). Both mOS and mPFS were longer in IDH-mutant patients. The present study was one of the first real life analyses of regorafenib in recurrent glioblastoma. The results were in line with the REGOMA trial. Age did not appear to be a prognostic factor, thus suggesting that treatment choice should not be different in elderly. MGMT methylation appeared to influence OS. To the best of our knowledge, this was the first report of regorafenib activity in older patients and, while the results were statistically significant, these should be confirmed in further studies.
RESUMO
BACKGROUND: Malignant pleural mesothelioma (MPM) is an invasive, aggressive pleural tumor with a predominantly local spread. The objective of this study was to assess thoracic ultrasound (TUS) as an imaging modality with high sensitivity for the identification of malignant pleural involvement and in order to guide pleural biopsies. METHODS: In this retrospective single-center study between January 2018 and June 2022, 51 consecutive patients with impassable circumferential pleural thickening underwent TUS at the Thoracic Surgery Unit of the Vanvitelli University of Naples. Pleural biopsies were performed, and then large and multiple samples were sent to the pathological anatomy for histological examination. RESULTS: In all patients who underwent ultrasound examination, we chose the optimal point of entry to perform pleural biopsies and selected the areas of greater thickening without pleural effusion. No patient had any complications. No drainage tubes were placed after the pleural biopsies and no pneumothorax was present during the following days of hospitalization. The patients were discharged on the second postoperative day. CONCLUSION: With TUS the precise pleural thickening localization, local infiltration, mass extent, its nature (solid, cystic or complex) and ultrasound features can be easily defined. Furthermore, ultrasound is more economical than computed tomography and avoids the risks associated with radiation. Thoracic ultrasound is an important component of the diagnostic procedure in detecting a safe entry site for biopsies of MPMs.

INTRODUCTION: Central airway tumors involving the trachea and main-stem bronchi are a common cause of airway obstruction and a significant cause of mortality among the patients of thoracic diseases with respiratory failure. Debulking in rigid bronchoscopy is quick, safe, and effective. It can be complex and hard in patients with severe bronchial or tracheal obstruction and/or with intraluminal bleeding tumors because of inadequate distal airway control. We have used laser tube as a new technique of ventilation for severe central airway obstruction. MATERIALS AND METHODS: Forty-six patients with severe airway obstruction undergoing rigid bronchoscopy from September 2020 to June 2022 at the Thoracic Surgery Department of the University L. Vanvitelli of Naples underwent placement of laser tube. RESULTS: In all patients who underwent rigid bronchoscopy with the use of the laser tube, a reduction of obstruction of more than 50% was obtained and in all patients no hypoxia (saturation < 88%), nor hypercapnia, nor significant bleeding were reported. DISCUSSION: The results of this study suggest that rigid bronchoscopic debulking with the use of laser tube is a safe and effective technique in the management of central airway obstruction. CONCLUSIONS: The use of the laser tube allows the monitoring of gas exchange, which controls hypoxemia. Thanks to the double cuff put distally to the tracheal obstruction or in the contralateral bronchus to the obstructed one, the laser tube prevents the flooding of blood from debulking below the stenosis. Rigid bronchoscopy with laser tube will expand its use in the future.

Aim: Head and neck squamous cell cancer (HNSCC) is the ninth most common tumor worldwide. Neck lymph node (LN) status is the major indicator of prognosis in all head and neck cancers, and the early detection of LN involvement is crucial in terms of therapy and prognosis. Diffusion-weighted imaging (DWI) is a non- invasive imaging technique used in magnetic resonance imaging (MRI) to characterize tissues based on the displacement motion of water molecules. This review aims to provide an overview of the current literature concerning quantitative diffusion imaging for LN staging in patients with HNSCC. Methods: This systematic review performed a literature search on the PubMed database (https://pubmed.ncbi.nlm.nih.gov/) for all relevant, peer-reviewed literature on the subject following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) criteria, using the keywords: DWI, MRI, head and neck, staging, lymph node. Results: After excluding reviews, meta-analyses, case reports, and bibliometric studies, 18 relevant papers out of the 567 retrieved were selected for analysis. Conclusions: DWI improves the diagnosis, treatment planning, treatment response evaluation, and overall management of patients affected by HNSCC. More robust data to clarify the role of apparent diffusion coefficient (ADC) and DWI parameters are needed to develop models for prognosis and prediction in HNSCC cancer using MRI.
RESUMO
INTRODUCTION: Staging of the mediastinum lymph nodes involvement in patients with non-small cell lung cancer (NSCLC) is an important prognostic factor determining the most appropriate multimodality treatment plan. The objective of this study is to assess ultrasound characteristics of mediastinal lymph nodes metastasis and effectiveness of intraoperative ultrasound-guided mediastinal nodal dissection in patients with resected NSCLC. MATERIALS AND METHODS: All patients undergoing video-assisted thoracoscopic surgery lobectomy and pulmonary lymphadenectomy from November 2020 to March 2022 at the thoracic surgery department of the Vanvitelli University of Naples underwent intraoperative ultrasound-guided mediastinal lymph nodal dissection. RESULTS: This study evaluates whether individual B-mode features and a compounding thereof can be used to accurately and reproducibly predict lymph node malignancy. DISCUSSION: Intraoperative ultrasound, during systematic mediastinal lymph node dissection, is helpful in preventing lesion to mediastinal structures. Pathological nodal sonographic characteristics are round shape, short-axis diameter, echogenicity, margin, the absence or presence of coagulation necrosis sign, and the absence or presence of central hilar structure, increased color Doppler flow, the absence or presence of calcification, and nodal conglomeration. Operating time was not substantially prolonged. The procedure is simple, safe and highly accurate. CONCLUSIONS: Ultrasonic techniques allow surgeons to detect the relationship between lymph nodes and surrounding large blood vessels during biopsy, improving the safety and simplicity of the operation, increasing the number of harvested lymph nodes, and reducing the risk of intraoperative injury; it is a fast, easily reproducible, and inexpensive method.

(1) Background: Recurrent and/or metastatic patients with head and neck squamous cell carcinoma show a poor prognosis, which has not changed significantly in 30 years. Preserving quality of life is a primary goal for this subset of patients; (2) Methods: A group of 19 physicians working in South Italy and daily involved in head and neck cancer care took an anonymous online survey aimed at revealing the level of knowledge and the application of communication techniques in daily patient care; (3) Results: Several specialists, 18 out 19 (95%), considered that patient participation in therapeutic choices is mandatory. The main obstacles to complete and reciprocate communication still consist of lack of time and staff, but also in the need for greater organization, which goes beyond the multidisciplinary strategy already used; (4) Conclusions: A greater impulse to training and updating on issues related to counseling can improve communication between the different clinicians involved in the treatment plan.

OBJECTIVES: Application of video-assisted thoracoscopy brought lung surgery into the minimally invasive era; the lack of tactile feedback using VATS, remains a disadvantage because surgeons are unable to locate lesions with a finger or device. This study aimed to investigate the effectiveness, the applicability and the utility of intraoperative ultrasound (IU), for the localization of small ground-glass opacity (GGO) lesions in the parenchyma, as a guide in finding their margins in a deflated lung. MATERIALS AND METHODS: We included 15 consecutive patients undergoing diagnostic resection of GGOs via VATS in the Thoracic Surgery Unit of the University of 'Luigi Vanvitelli' of Naples from November 2019 to December 2021. They were under general anaesthesia, when the lung had been collapsed, the probe was placed in the region where the target lesion was thought to reside on the basis of low-dose computed tomography scanning. GGO could be identified their sizes, echo levels and posterior echo was recorded by IU when the lung was completely deflated. RESULTS: We conducted a retrospective single-centre study. All GGOs were identified by IU. The mean size and depth were 14.1 ± 0.5 and 4.8 ± 0.3 mm, respectively. Six (40%) lesions had hyperechoic patterns, 9 (60%) had mixed echogenicity where the hyperechoic patterns were irregularly mixed with hypoechoic patterns. The final diagnoses included 2 (15%) atypical adenomatous hyperplasia; 2 (15%) adenocarcinomas in situ; 3 (23%) minimally invasive adenocarcinomas and 6 (46%) invasive adenocarcinomas. CONCLUSIONS: The results of our study showed that IU could safely and effectively detect GGOs.

Glioblastoma multiforme (GBM) is one of the most frequent and aggressive primary tumors in the central nervous system, representing more than 60% of all brain tumors in adults. Primary GBM remains incurable with a poor prognosis both for limited therapeutic alternatives and for a high risk of progression or recurrence. In fact, at recurrence, the few treatment options available, and often characterized by limited effectiveness, have always been an Achilles' heel. The recent approval of second line of regorafenib, a multikinase inhibitor, has given hope after several years of darkness for new therapies in the treatment of GBM. Indeed, in the REGOMA trial, a phase 2 study, regorafenib was the first drug to show a statistically significant improvement in median overall survival compared with lomustine group, usually used in the second-line treatment after temozolomide failure. We report a case of a 43-year-old patient affected by GBM in treatment with regorafenib in third line of therapy with good disease control and long PFS.
