RESUMO
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.

BACKGROUND: Exosomes are nanosized vesicles released from all cells into surrounding biofluids, including cancer cells, and represent a very promising direction in terms of minimally invasive approaches to early disease detection. They carry tumor-specific biological contents such as DNA, RNA, proteins, lipids, and sugars, as well as surface molecules that are able to pinpoint the cellular source. By the above criteria, exosomes may be stratified according to the presence of tissue and disease-specific signatures and, due to their stability in such biofluids as plasma and serum, they represent an indispensable source of vital clinical insights from liquid biopsies, even at the earliest stages of cancer. Therefore, our work aimed to isolate and characterize LCa patients' derived exosomes from serum by Flow Cytometry in order to define a specific epitope signature exploitable for early diagnosis. METHODS: Circulating exosomes were collected from serum collected from 30 LCa patients and 20 healthy volunteers by the use of antibody affinity method exploiting CD63 specific surface marker. Membrane epitopes were then characterized by Flow cytometry multiplex analysis and compared between LCa Patients and Healthy donors. Clinical data were also matched to obtain statistical correlation. RESULTS: A distinct overexpression of CD1c, CD2, CD3, CD4, CD11c, CD14, CD20, CD44, CD56, CD105, CD146, and CD209 was identified in LCa patients compared to healthy controls, correlating positively with tumor presence. Conversely, CD24, CD31, and CD40, though not overexpressed in tumor samples, showed a significant correlation with nodal involvement in LCa patients (p < 0.01). CONCLUSION: This approach could allow us to set up a cost-effective and less invasive liquid biopsy protocol from a simple blood collection in order to early diagnose LCa and improve patients' outcomes and quality of life.

BACKGROUND: Recent studies have highlighted the importance of the cell-free DNA (cfDNA) methylation profile in detecting breast cancer (BC) and its different subtypes. We investigated whether plasma cfDNA methylation, using cell-free Methylated DNA Immunoprecipitation and High-Throughput Sequencing (cfMeDIP-seq), may be informative in characterizing breast cancer in patients with BRCA1/2 germline mutations for early cancer detection and response to therapy. METHODS: We enrolled 23 BC patients with germline mutation of BRCA1 and BRCA2 genes, 19 healthy controls without BRCA1/2 mutation, and two healthy individuals who carried BRCA1/2 mutations. Blood samples were collected for all study subjects at the diagnosis, and plasma was isolated by centrifugation. Cell-free DNA was extracted from 1 mL of plasma, and cfMeDIP-seq was performed for each sample. Shallow whole genome sequencing was performed on the immuno-precipitated samples. Then, the differentially methylated 300-bp regions (DMRs) between 25 BRCA germline mutation carriers and 19 non-carriers were identified. DMRs were compared with tumor-specific regions from public datasets to perform an unbiased analysis. Finally, two statistical classifiers were trained based on the GLMnet and random forest model to evaluate if the identified DMRs could discriminate BRCA-positive from healthy samples. RESULTS: We identified 7,095 hypermethylated and 212 hypomethylated regions in 25 BRCA germline mutation carriers compared to 19 controls. These regions discriminate tumors from healthy samples with high accuracy and sensitivity. We show that the circulating tumor DNA of BRCA1/2 mutant breast cancers is characterized by the hypomethylation of genes involved in DNA repair and cell cycle. We uncovered the TFs associated with these DRMs and identified that proteins of the Erythroblast Transformation Specific (ETS) family are particularly active in the hypermethylated regions. Finally, we assessed that these regions could discriminate between BRCA positives from healthy samples with an AUC of 0.95, a sensitivity of 88%, and a specificity of 94.74%. CONCLUSIONS: Our study emphasizes the importance of tumor cell-derived DNA methylation in BC, reporting a different methylation profile between patients carrying mutations in BRCA1, BRCA2, and wild-type controls. Our minimally invasive approach could allow early cancer diagnosis, assessment of minimal residual disease, and monitoring of response to therapy.

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.

Microsatellite instability (MSI) has been identified in several tumors arising from either germline or somatic aberration. The presence of MSI in cancer predicts the sensitivity to immune checkpoint inhibitors (ICIs), particularly PD1/PD-L1 inhibitors. To date, the predictive role of MSI is currently used in the selection of colorectal cancer patients for immunotherapy; moreover, the expansion of clinical trials into other cancer types may elucidate the predictive value of MSI for non-colorectal tumors. In clinical practice, several assays are used for MSI testing, including immunohistochemistry (IHC), polymerase chain reaction (PCR) and next-generation sequencing (NGS). In this review, we provide an overview of MSI in various cancer types, highlighting its potential predictive/prognostic role and the clinical trials performed. Finally, we focus on the comparison data between the different assays used to detect MSI in clinical practice.

Spindle cell larynx carcinoma (SpCC) represents around 3% of laryngeal cancers. It is originated by a single cancer stem cell undergoing epithelial to mesenchymal transition. This explains the aggressiveness, the peculiar resistance to conventional therapy and the frequent relapses. We focused on this particular cancer subset characteristics in patients, in early and advanced stages primarily aiming to define and highlight the differences with Laryngeal Squamous Cell Carcinoma (LSCC) focusing on clinical features, treatments, follow-up and survival in a patient's cohort composed by comparable cases from two subgroups.

INTRODUCTION: Concurrent platinum-based chemoradiation currently represents the standard treatment for advanced head and neck cancer (HNC), but it induces a significant toxicity, in particular among elderly patients. Elderly and unfit patients have been underrepresented in clinical trials and there is a need for tailored guidelines. METHODS: A retrospective review of clinical data of HNC patients treated at the Operative Oncology Unit of the San Giovanni di Dio Hospital in Frattamaggiore (Naples, Italy) was performed. At study entry, a comprehensive assessment including absolute contraindications for cisplatin use, as well as comorbidities, socioeconomic status, BMI, and weight loss, was performed. The treatment included high-dose radiotherapy plus weekly cetuximab (initially at a dose of 400 mg/m2of body surface area and thereafter at 250 mg weekly during the whole radiotherapy). The aim of this study was to evaluate the activity and toxicity of this schedule in a series of patients aged older than 69 years. RESULTS: Between May 30, 2013, and March 30, 2015, sixty-four patients (age range, 69-87 years; median age, 73.7 years; male/female ratio, 46/18) were treated. The overall response rate was 67% in this series of patients. The disease control rate was 76%. Disease progression was recorded in 25% of the patients. The median duration of loco-regional control was 17 months (range, 15.8-17.7 months). PFS was 14.8 months (range, 13.9-15.5 months). The overall survival was 34 months, with a median follow-up of 41.0 months (range, 31.1-36.8 months). The main grade 3/4 adverse events were acne rash in 52% and radiation dermatitis in 32% of the cases. CONCLUSION: Cetuximab plus radiotherapy appears to be feasible and active in elderly patients unsuitable for cisplatin treatment. The treatment was supported by a favorable toxicity profile.

OBJECTIVES: This study evaluates maintenance cetuximab administered every 2 weeks (q2w) after chemotherapy plus cetuximab as first-line treatment in a series of patients with head and neck squamous cell cancer and compares the results with those obtained in a historical control group of patients receiving weekly cetuximab. METHODS: After chemotherapy plus cetuximab as first-line treatment, in Group A, 36 patients enrolled from October 2016 to November 2017, received biweekly cetuximab, administered at 500 mg/m2. Group B was a control group of patients treated at our institution from August 2015 to September 2016 and received weekly infusion of cetuximab at 250 mg/m2. RESULTS: Confirmed overall response rates were, respectively, 19% for Group A and 17% for Group B according to intention-to-treat analysis. During the maintenance treatment, median progression-free survival (PFS) and median overall survival (OS) were similar for both groups (PFS, 4.8 and 4.4 months; OS, 9.0 and 7.9 months; in Groups A and B, respectively). The most common adverse events among treated subjects included fatigue, rash, and hypomagnesemia. CONCLUSION: Maintenance therapy with simplified biweekly cetuximab is a convenient, effective, and well-tolerated regimen in patients with recurrent and/or metastatic head and neck squamous cell carcinoma.

AIM: In this prospective multicenter real-life observational cohort study, we investigated the acceptance, adherence and safety of regorafenib, in the treatment of metastatic colorectal cancer patients. PATIENTS & METHODS: A total of 136 patients were recruited at six oncological hospital sites in southern Italy. The adherence to the treatment was measured with patient-completed medication diaries, physician interviews and pill counts. RESULTS: We found a statistically significant improvement of therapy adhesion by the acceptance questionnaire. The Eastern Cooperative Oncology Group performance status, the level of acceptance, the educational level and the concomitant usage of oral medications influenced the adherence to the treatment. CONCLUSION: Patients' level of education, concomitant other oral medications and patients' general clinical condition may influence the adherence to regorafenib.

Metronomic chemotherapy (mCT), a frequent administration of low-dose chemotherapy, allows prolonged treatment duration and minimizes the toxicity of standard-dose chemotherapy. mCT has multiple actions against cancer cells including inhibition of angiogenesis and modulation of the immune system. A number of studies lend support to the clinical efficacy of mCT in advanced breast cancer and non-small-cell lung cancer. However, further evidence is necessary to describe the optimal use of mCT and to identify suitable patients. Oral vinorelbine has emerged as a promising metronomic treatment in patients with metastatic breast cancer and non-small-cell lung cancer and is the only orally available microtubule-targeting agent. This paper reviews current evidence on metronomic oral vinorelbine, discusses its management and defines a suitable patient profile on the basis of a workshop of Italian experts.

The therapeutic approach to advanced or metastatic solid tumors, either with chemotherapy or targeted therapies, is mainly palliative. Resistance to chemotherapy occurs very frequently and is one of the most important reasons for disease progression. Immunotherapy has the potential to mount an ongoing, dynamic immune response that can kill tumor cells for an extended time after the conventional therapy has been administered. Such a long-lasting response is potentially able to completely eradicate tumor cells, rather than producing only a temporary killing of cells. The most promising immune-based treatments are monoclonal antibodies that act as checkpoint inhibitors (e.g. ipilimumab and nivolumab), adoptive cell therapy (e.g. T-cells expressing chimeric antigen receptors) and vaccines (e.g. sipuleucel-T). Ipilimumab is currently approved for the treatment of metastatic melanoma and sipuleucel-T is approved for advanced prostate cancer. There is great interest in immunotherapy in other solid tumors, potentially used alone or in a multimodal fashion with chemotherapy and/or biological drugs. In this paper, we review recent advances in immuno-oncology in solid malignancies (except melanoma) as were discussed at the inaugural meeting of the Campania Society of Oncology Immunotherapy (SCITO).

AIM: We investigated the role of erythropoietin (EPO) in reducing anemia and preventing the development of psychological distress in patients treated with chemotherapy. PATIENTS & METHODS: This prospective observational study enrolled 591 adult patients receiving EPO at a dose of 30,000 IU administered once weekly for chemotherapy-induced anemia (mean baseline hemoglobin [Hb] level was 9.55 g/dl) over a 12-month period. RESULTS: The majority of patients (371 [71%] patients) achieved a Hb increase >2 g/dl after 4 weeks of treatment. Interestingly, the nonresponder group had a statistically significant deterioration of their psychological conditions as indicated by psychological distress score (p = 0.01). However, within the group of responders to EPO, the Psychological Distress Inventory score remained unchanged. In the present study, severe side effects associated with EPO were not recorded. CONCLUSION: Hb increase, induced by EPO, ameliorates the psychological conditions of cancer patients.

BACKGROUND AND OBJECTIVE: The identification of mutation hot spots in the isocitrate dehydrogenase (IDH) genes is one of the most important cancer genome-wide sequencing discoveries with relevant impact in the treatment of some orphan tumors. These genes were mostly found mutated in lower-grade gliomas (LGGs), acute myeloid leukaemia (AML), myelodysplastic syndromes (MDS) and myeloproliferative neoplasms (MPNs) and in cholangiocarcinoma. This aberrant genomic condition represents a therapeutic target of great interest in cancer research, especially in AML, given the limitations of currently approved therapies in this field. In this review, we investigate the role of IDH mutation and the mutant IDH (mIDH)- targeted therapies for cholangiocarcinoma and glioma. METHODS: Here, we provide an overview of the IDH mutation role and discuss its role in tumorigenesis and progression of some solid cancers, in which the therapeutic strategy can be completely changed thanks to these brand-new therapeutic options. KEY CONTENT AND FINDINGS: The encouraging early clinical data demonstrated to be a proof of concept for investigational mIDH1/2 inhibitors in tumors with a paucity of therapeutic possibilities. CONCLUSIONS: Moreover, we list the most important randomised clinical trials still active with their preliminary results.
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
MicroRNAs (miRNAs) are involved in post-transcriptional gene expression regulation and in mechanisms of cancer growth and metastases. In this light, miRNAs could be promising therapeutic targets and biomarkers in clinical practice. Therefore, we investigated if specific miRNAs and their target genes contribute to laryngeal squamous cell carcinoma (LSCC) development. We found a significant decrease of miR-449a in LSCC patients with nodal metastases (63.3%) compared with patients without nodal involvement (44%). The AmpliSeq Transcriptome of HNO-210 miR-449a-transfected cell lines allowed the identification of IL6-R as a potential target. Moreover, the downregulation of IL6-R and the phosphorylation reduction of the downstream signaling effectors, suggested the inhibition of the IL-6 trans-signaling pathway. These biochemical effects were paralleled by a significant inhibition of invasion and migration in vitro and in vivo, supporting an involvement of epithelial-mesenchymal transition. These findings indicate that miR-449a contributes to suppress the metastasization of LSCC by the IL-6 trans-signaling block and affects sensitivity to external stimuli that mimic pro-inflammatory conditions.
RESUMO
OBJECTIVE: The management of hepatocellular carcinoma (HCC) in elderly patients is significantly more complicated than in younger patients because of medical comorbidities, advanced status at diagnosis, reduced liver function and altered drug pharmacokinetics. Our objective was a revision of the charts of unselected elderly patients with HCC being treated with a reduced starting dose of sorafenib. METHODS: Activity, adverse events and quality of life were evaluated during the treatment. Sixty patients (47 males and 13 females) aged more than 70 years old (range 70-90, median 76 years) were retrospectively reviewed. RESULTS: One complete and one partial response were achieved in the series (overall response rate 3.3%). Stable disease accounted for 76.6% (46 out of 60 patients). The disease control rate (complete plus partial response plus stable disease) was 80%. Median time to progression (TTP) was 7.0 months (95% CI, 5.2-8.7 months) and median survival was 10.0 months (95% CI, 5.0-14.9 months). Thrombosis correlated to TTP. Full doses of sora-fenib were reached in 11 out of 60 patients (18.3%). The evaluation of quality of life did not show any significant change during the study. CONCLUSIONS: Sorafenib at a reduced dose can be safely used in elderly HCC patients with maintenance of activity and increased tolerability.

PURPOSE: Oxaliplatin-induced neuropathy is a dose-related side effect which occurs in almost 40 % of patients treated with oxaliplatin. Aim of the present study was to identify reliable clinical factors predicting its development and duration. METHODS: One hundred sixty-nine completely resected colorectal cancer patients treated with adjuvant Folfox IV regimen were retrospectively included. The following pre-treatment clinical parameters were collected: hypocalcaemia, hypomagnesaemia, hypoalbuminaemia, anaemia, diabetes, chronic renal failure (CRF), folate deficiency, vitamin B(12) deficiency, number of cycles received and habit to alcohol consumption. Incidence, grade (NCI-CTCAE v.3) and duration of neuropathy were recorded. RESULTS: Incidence of neuropathy was found to be higher in patients with pre-treatment anaemia (p = 0.001), hypoalbuminaemia (p = 0.01) and hypomagnesaemia (p = 0.001) as well in those with habit to alcohol consumption (p = 0.003). Neuropathy durations were conversely associated with age, being longer in younger patients (p = 0.03), and again with hypoalbuminaemia (p = 0.04) and hypomagnesaemia (p = 0.002). No correlation was found with gender, hypocalcaemia, diabetes and CRF. The correlation between vitamin B(12) and folate levels and the development of neurotoxicity were not analysed because of the high number of missing data in the population. CONCLUSIONS: Age, anaemia, hypoalbuminaemia, hypomagnesaemia and alcohol consumption are reliable and easily assessable clinical factors predicting incidence and length of oxaliplatin-induced neuropathy.

Introduction: Head and neck carcinoma (HNC) is a disease with a poor prognosis despite currently available treatments. The management of patients with this tumor is often complicated by several comorbidities. Among these, diabetes is the second most frequent and its influence on the prognosis is not known. Methods: In this work, we collected data on progression free survival (PFS) and overall survival (OS) of one hundred twenty-three patients with HNC who received biweekly cetuximab maintenance treatment after first-line chemotherapy. We then compared the survival of nondiabetic patients versus diabetics' one. Results: Surprisingly, both PFS (4 vs. 5 months, HR 2.297, p < 0.0001) and OS (7 vs. 10 months, HR 3.138, p < 0.0001) were in favor of diabetic patients, even after excluding other clinical confounding factors. In addition, we also studied survivals in patients taking metformin, a widely used oral antidiabetic drug that has demonstrated antitumor efficacy in some cancers. Indeed, diabetic patients taking metformin had better PFS and OS than those not taking it, 7 vs. 5 months (HR 0.56, p = 0.0187) and 11 vs. 8.5 months (HR 0.53, p = 0.017), respectively. Discussion: In conclusion, real-world outcomes of biweekly cetuximab maintenance remain comparable to clinical trials. The prognostic role of diabetes and metformin was confirmed to be significant in our series, but further prospective studies are needed for a definitive evaluation.
RESUMO
BACKGROUND: Psychological distress has been associated with greater physical symptom severity, suffering, and mortality in cancer patients. For this reason, today, psychological care represents a fundamental tool for improving the quality of life of cancer patients. METHODS: From September 2021 to May 2022, 170 newly diagnosed cancer patients, were enrolled in the observational study at Medical Oncology Unit, "San Giovanni di Dio" Hospital. Before the start of oncological treatment, they were subjected to the Kessler 10 (K10) test, a validated measure of non-specific symptoms of psychological distress of the past 4 weeks. On the basis of the score, they were divided into three groups: low [10-19], moderate [20-29] and high [30-50] distress. After 3 months of psychological therapy, they repeated the test. RESULTS: Majority of patients were female (74.1%), aged <70 years (78.2%). The most represented tumours were breast (47.6%), colon (15.3%), urothelial (10.6%) and lung (7.6%) cancer and most patients started intravenous chemotherapy treatment (74.7%) rather than oral therapy. The previous remote pathological history and the family cancer history of the patients were also evaluated. Finally, marital status, schooling and employment status were recorded. At baseline we found 55, 72, and 43 patients with a low, moderate and high psychological distress, respectively. After the 3 months of psychotherapy, we re-administered the K10 test and we found a radical improvement in the degree of psychological distress (96 patients had a low score, 62 with a moderate score and just 12 patients with a high score). The great reduction in the score in K10 was statistically significant with a P value of <0.0001. The reduction of the K10 score was observed indiscriminately in all subgroups analysed. A statistically significant difference was observed between patients with different education levels (low 56% vs. high 32% of reduction in K10 score). Furthermore, the improvement in psychological health was greater in unemployed patients than in workers. CONCLUSIONS: The use of the K10 test is helpful in monitoring the degree of psychological distress of patients facing the diagnosis of cancer and who are about to start oncological treatment. Psychotherapy is effective in reducing the distress of these patients just a few months after starting treatment.
