RESUMO

The presence in the blood of patients with solid tumors of circulating cells expressing both epithelial and leukocyte markers (dual-positive cells, DPcells), has often been reported, though it has never been investigated in detail. A recent study suggested that DPcells are hybrid cells derived from the fusion of tumor cells with macrophages. Such fusion hybrids acquire macrophage-associated features endowing them with accelerated growth, increased motility, enhanced invasion activity and thus, a higher efficiency in metastasis formation. However, no direct evidence proving the tumor origin of circulating DPcells was provided in patients. Here we contribute a review of literature data on DPcells and on the hybrid theory with the aim of putting the current evidence both in a biological and clinical perspective and to generate new hypotheses on the mechanisms underlying tumor progression. To add further biological and clinical context to our literature review, we also report some preliminary data from our laboratory on the identification of DPcells in several solid tumors and confirmation of their malignant genotype, thus classifying them as DP-CTCs.

RESUMO

OBJECTIVES: To identify and validate baseline magnetic resonance imaging (b-MRI) radiomic features (RFs) as predictors of disease outcomes in effectively cured head and neck squamous cell carcinoma (HNSCC) patients. MATERIALS AND METHODS: Training set (TS) and validation set (VS) were retrieved from preexisting datasets (HETeCo and BD2Decide trials, respectively). Only patients with both pre- and post-contrast enhancement T1 and T2-weighted b-MRI and at least 2 years of follow-up (FUP) were selected. The combination of the best extracted RFs was used to classify low risk (LR) vs. high risk (HR) of disease recurrence. Sensitivity, specificity, and area under the curve (AUC) of the radiomic model were computed on both TS and VS. Overall survival (OS) and 5-year disease-free survival (DFS) Kaplan-Meier (KM) curves were compared for LR vs. HR. The radiomic-based risk class was used in a multivariate Cox model, including well-established clinical prognostic factors (TNM, sub-site, human papillomavirus [HPV]). RESULTS: In total, 57 patients of TS and 137 of VS were included. Three RFs were selected for the signature. Sensitivity of recurrence risk classifier was 0.82 and 0.77, specificity 0.78 and 0.81, AUC 0.83 and 0.78 for TS and VS, respectively. VS KM curves for LR vs. HR groups significantly differed both for 5-year DFS (p<.0001) and OS (p=.0004). A combined model of RFs plus TNM improved prognostic performance as compared to TNM alone, both for VS 5-year DFS (C-index: 0.76 vs. 0.60) and OS (C-index: 0.74 vs. 0.64). CONCLUSIONS: Radiomics of b-MRI can help to predict recurrence and survival outcomes in HNSCC.

RESUMO

PURPOSE: To describe the management and outcomes of loco-regionally advanced (stages III-IV) laryngeal cancer (LRALC) in elderly patients. METHODS: Clinical records of 88 LRALC patients treated at our Institution from 2002 to 2017 were retrospectively reviewed. Patients were divided in 2 subgroups: age > 65 years (elderly) and age ≤ 65 years (controls). Survivals were estimated with Kaplan-Meier method and compared with log-rank test, multivariate analysis were performed with Cox proportional hazard methods. RESULTS: Eighty-eight LRALC patients were included: 45 elderly and 43 controls. Median follow-up was 55.3 months. Median age was 66 years (range 41-84) in the overall population, 72 years (range 66-84) in the elderly cohort. The majority (98%) of elderly patients had at least one comorbidity (ACE27 1-3), while ACE27 was 0 in 37% of controls (p = 0.0001). ECOG PS was 0 in 42% of elderly vs 79% of controls (p = 0.0029). Clinical stage (TNM eighth edition) was III in 67%, IVA in 22% and IVB in 11%. Treatment consisted in total laryngectomy (TL) in 55%, chemo-radiation in 29%, exclusive radiotherapy in 9%, and conservative surgery in 7%. In elderly patients 2-year disease-free and overall survivals were 58% and 74%, respectively. Multivariate analysis performed on the overall group of 88 patients showed that age (HR 1.07, p = 0.0006) and TNM (for both 7th and 8th Editions HR 0.27 for stage III vs IV, p = 0.0005) maintained an independent statistical significant association with OS. CONCLUSIONS: In this monocentric cohort, age and TNM confirmed their independent prognostic role in LRALC patients. Organ-preservation is still an unmet need in a significant portion of elderly patients.

RESUMO

BACKGROUND: The treatment of patients with recurrent and/or metastatic (R/M) salivary gland adenoid cystic carcinoma (ACC) remains an unmet need. METHODS: Patients with R/M disease with a history of clinical or symptomatic disease progression within 6 months and a maximum of 1 previous line of chemotherapy or a multiple kinase inhibitor received oral lenvatinib at a dose of 24 mg/day. The primary endpoint was the objective response rate; secondary endpoints included quality of life (QOL) (according to the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 Items [EORTC QLQ-C30] and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core Module Head and Neck Module [EORTC QLQ-H&N35]), progression-free survival and overall survival, duration of response, and toxicities. RESULTS: Twenty-eight patients with R/M ACC were enrolled. Among 26 evaluable patients, 3 partial responses (11.5%) were reported. Target lesion reductions between 23% to 28% were observed in 4 of 20 patients with stable disease. Treatment-related adverse events were frequent (all grades, 96%; grade≥3 in 50% of cases according to version 4.03 of the National Cancer Institute Common Terminology Criteria for Adverse Events). The dose of lenvatinib was reduced in 24 patients, whereas in 21 patients the dose was reduced within the first 12 weeks and 4 patients maintained the full dose throughout treatment. The QOL deteriorated between baseline and 6 months with regard to Fatigue and Dry Mouth. There was no evidence of changes in Swallowing and Physical Functioning. At a median follow-up of 29 months, 2 patients remained on treatment, 10 patients were off protocol for disease progression and were alive with disease, and 14 patients had died of disease progression. The median overall survival, progression-free survival, and duration of response were 27 months, 9.1 months, and 3.1 months, respectively. CONCLUSIONS: Lenvatinib appears to have modest activity in ACC. Toxicities are common but manageable and QOL was found to deteriorate in some domains.

RESUMO

BACKGROUND: Recurrent or metastatic (R/M) skin squamous cell carcinoma (sSCC) not amenable of surgery or irradiation may benefit from systemic therapies. Epidermal growth factor receptor (EGFR) inhibitors and, more recently, immune checkpoint blockers (ICBs) showed activity in R/M sSCC. In this study, we aimed at exploring the possible role of PD-L1 expression in predicting response to anti-EGFR agents. METHODS: Patients affected by R/M sSCC, treated with pan-HER inhibitor dacomitinib or with platinum-based chemotherapy with cetuximab (CT-cet) from 2010 to 2016, were considered. PD-L1 expression was assessed with immunohistochemistry on tumor cells (TCs) and on microenvironment (TC and tumor-infiltrating lymphocyte [IC] scores, respectively). Prognostic role of PD-L1 and the correlation with response to EGFR inhibitors and survival were analyzed. RESULTS: Twenty-eight R/M sSCCs were analyzed (19 treated with dacomitinib, 9 with CT-cet). TC and IC were negative in 82 and 45% of cases, respectively; 15% sSCCs were both TC and IC positive. Progression-free survival (PFS) was longer in IC-positive cases (median 7.5 months vs. 2.1 in IC0, p = 0.02). No statistically significant differences were observed between PD-L1 expression and both overall survival and response rates. CONCLUSION: PD-L1 expression in microenvironment predicted better PFS. The combination of EGFR inhibitors and ICB could help deepening the knowledge about the interrelations between the EGFR and PD-1/PD-L1 pathways.

RESUMO

Aim: Reporting toxicities of targeted therapies (TTs) and immunotherapy in oncology requires special attention. Materials & methods: We identified TTs and immunotherapies approved by the US FDA for solid malignancies in the adult population. Publications were reviewed according to a 24-point score based on the Consolidated Standards of Reporting Trials guidance. Results: We identified 81 trials (>45,000 patients). The experimental drug was studied as single agent in 51% of the cases; setting of disease was mainly (95%) advanced/metastatic. Lowest scores in adverse event (AE) description regarded: reporting recurrent/late toxicities and duration of the AEs (>90%), time of occurrence and indication of all-grade AEs (>75%). Conclusion: Suboptimal reporting of AEs in trials leading to approval of TTs and immunotherapy was shown. Improving AE descriptions should be a priority in ongoing trials.

RESUMO

BACKGROUND: Pediatric salivary gland carcinomas (SGCs) are very rare. They differ from the adult SGCs in terms of epidemiologic and clinical behavior, being generally limited only to selected histotypes (e.g. low-grade mucoepidermoid [LG-MEC] and acinic cell cancer [AcCC]) and characterized by very good outcome. Our aim was to investigate therapeutic targets on a series of pediatric SGCs by immunohistochemical and molecular analysis. METHODS: A retrospective analysis was performed to search for cases of pediatric SGCs in the database of the Pediatric Oncology Unit at the Istituto Nazionale Tumori and in the Pathology database at the Gerhard-Seifert-Reference-Centre. The expressions of the most common tyrosine-kinase receptors (TKRs) reported in adult SGCs as EGFR, HER2, KIT and hormonal receptors (HRs) (estrogen α and ß, progesterone as well as androgen receptors) were investigated. CRTC1/MAML2 and MYB/NFIB were also analyzed in MEC and adenoid cystic carcinoma cases, respectively. RESULTS: Twenty-nine cases were identified: 22 MECs, 4 AcCCs, 1 adenoid cystic carcinoma (ACC), 1 adenocarcinoma not otherwise specified and 1 sialoblastoma. EGFR was the most expressed TKR, whilst HRs were negative in all cases except for ER-ß in four cases of MEC. CRTC1/MAML2 was present in 15 out of 17 evaluable MEC cases and MYB/NFIB was identified in the ACC case. CONCLUSIONS: The immunohistochemical and molecular profiles of pediatric SGCs analyzed in our series are similar to that observed in adults, especially for MEC, supporting a common biological background.

RESUMO

BACKGROUND: Human papilloma virus oral infection can be related to several factors including HIV infection, cigarette smoking, marijuana consumption and number of sexual partners. We conducted a study on oral HPV prevalence and clearance among the hosts of the San Patrignano community, a population considered at "high-risk" for HPV due to their previous habits. METHODS: From March 2007 to September 2010 all subjects were submitted to oropharyngeal brushing and saliva collection at baseline, after 6, 12 and 48 months (for subjects HPV positive at baseline). Samples were analyzed to detect HPV DNA and virus genotypes. The correlation between HPV prevalence and demographic, behavioral or immunological characteristics was assessed. RESULTS: Among 194 subjects, 30 (15%) were HPV positive with 25 (13%) high-risk (HR)-HPV at baseline brushing. At 12 months HPV infection was cleared in all cases. However at 48 months HPV was newly detected in 33% of subjects. A correlation between time spent in the community and increase in the ratio of "low-risk" (LR) HPV and HR-HPV was observed. HPV infection was not associated with age, gender, HIV status, HCV, alcohol and/or drug exposure, number of years spent in community, sex with drug-addicts and condom use. Only AIDS under antiretroviral treatment was inversely correlated with the risk of infection. CONCLUSIONS: At 1 year a complete HPV clearance was observed which could be related to adoption of healthier lifestyles of participants. New HPV infections were detected even in the absence of the recognized and declared risky behavioral factors, suggesting a re-expression from a latent infection.

RESUMO

BACKGROUND: Human papillomavirus (HPV)-positive and HPV-negative oropharyngeal squamous cell carcinomas (OSCCs) are two distinct entities. We defined the molecular profiles of druggable receptor tyrosine kinases (RTKs) in both groups. MATERIALS AND METHODS: E5 expression and RTK alterations were studied in 17 HPV-positive and 59 HPV-negative formalin-fixed OSCCs. RTK activation was explored in further 12 frozen OSCCs. RESULTS: The HPV-positive OSCCs showed E5 expression and 33.3% expressed low level of HER2. The HPV-negative OSCCs showed HER2 expression (31.2%), increased HER2 gene copy number (46.51%, P = 0.045) and HER2 activation through HER2/EGFR heterodimerisation; HER3 (51.06%, P = 0.008) and neuregulin (65.63%; P = 0.03) expression, HER3 activation and HER3/EGFR heterodimerisation; and increased IGF-1R copy number (40.50%, P = 0.021), high IGF-1R cDNA values (P = 0.002), IGF-1R activation and expression of IGF1/2 and amphiregulin. PI3KCA mutations/expression/increased gene copy number and PTEN mutations were found in both groups, whereas PTEN gene loss was only observed in the HPV-positive cases. CONCLUSION: Human papillomavirus-positive and HPV-negative OSCC showed different RTK profiles. In HPV-positive cases, it would be interesting to study the expression of E5, which may modulate EGFR turnover and activate VEGF and PDGFRß. In HPV-negative cases, HER3 may be a promising druggable biomarker that deserves further investigation. PI3KCA and PTEN alterations encourage the promising clinical evaluation of PI3K/mTOR inhibitor activity in OSCC, particularly in HPV-positive/PI3KCA-mutated OSCCs because they may be driven by PI3KCA mutation alone.

RESUMO

BACKGROUND: In a previous phase 2 trial, axitinib was active and well tolerated in patients with advanced thyroid cancer. In this second phase 2 trial, the efficacy and safety of axitinib were evaluated further in this population, and pharmacokinetic/pharmacodynamic relationships and patient-reported outcomes were assessed. METHODS: Patients (N = 52) with metastatic or unresectable, locally advanced medullary or differentiated thyroid cancer that was refractory or not amenable to iodine-131 received a starting dose of axitinib 5 mg twice daily. The primary endpoint was the objective response rate (ORR). Secondary endpoints included progression-free survival (PFS), overall survival (OS), safety, pharmacokinetic parameters, and patient-reported outcomes assessed with the MD Anderson Symptom Inventory questionnaire. RESULTS: The overall ORR was 35% (18 partial responses), and 18 patients had stable disease for ≥16 weeks. The median PFS was 16.1 months, and the median OS was 27.2 months. All-causality, grade ≥3 adverse events (>5%) were fatigue, dyspnea, diarrhea, decreased weight, pain in extremity, hypertension, decreased appetite, palmar-plantar erythrodysesthesia, hypocalcemia, and myalgia. Patients who had greater axitinib exposure had a longer median PFS. Quality of life was maintained during treatment with axitinib, and no significant deterioration in symptoms or interference in daily life caused by symptoms, assessed on MD Anderson Symptom Inventory subscales, were observed. CONCLUSIONS: Axitinib has activity and a manageable safety profile while maintaining quality of life, and it represents an additional treatment option for patients with advanced thyroid cancer.

RESUMO

Fosbretabulin tromethamine is a vascular disrupting agent, which is a type of drug that is designed to damage the vasculature (blood vessels) of cancer tumors, causing central necrosis. This drug showed activity against anaplastic thyroid cancer that was demonstrated in orthotopic xenograft models as well as in Phase I/II trials with or without carboplatin and paclitaxel combination therapy. In all of these studies, fosbretabulin was well tolerated.

RESUMO

AIMS: To evaluate technical issues and clinical outcomes after postoperative volumetric-modulated arc therapy (VMAT) in two cases of malignant lacrimal gland cancer. PATIENTS & METHODS: Patients were treated by postoperative VMAT and post-treatment clinical outcomes were followed-up to 18 months. RESULTS: Dosimetric results were acceptable and acute toxicity was manageable in both patients. No evidence of disease was found at latest follow-up. One patient underwent corneal transplant for central corneal ulceration, experiencing reduction of visual acuity. CONCLUSION: Postoperative VMAT for treatment of lacrimal gland tumors offers improved outcome, with manageable side effects. In the context of photon beam radiotherapy, VMAT emerged as a valuable treatment option for these malignant tumors.

RESUMO

Clear cell renal carcinoma (ccRCC) can occur in young people and could be associated with an aggressive behavior. While for the first-line treatment in metastatic disease, there is an agreement to rely on an immunotherapy (IO)-based combination regimen, no standard second-line regimens exist. Generally, tyrosine kinase inhibitors (TKIs) are employed, even in sequence, although no trials have demonstrated yet the best succession. Herein, we present the case of a 39-year-old male, with a very aggressive ccRCC with somatic VHL mutation and distant metastases at diagnosis. He was treated with four different lines of therapies, including TKIs, with progressive multiple tumor deposits. Lenvatinib alone as the fifth line was able to induce a remarkable and prolonged tumor shrinkage with manageable toxicities.

RESUMO

Although thyroid cancer (TC) is generally associated with a favourable prognosis, there are certain high-risk groups with a clear unmet therapeutic need. Unravelling the genomic landscape of TC has recently led to the development of novel effective targeted treatments. To date, these treatments have mostly been evaluated in non-randomised single-arm phase II clinical trials and are consequently non-reimbursed in several countries. Furthermore, most of these agents must be tailored to individual patient molecular characteristics, a context known as personalised cancer medicine, necessitating a requirement for predictive molecular biomarker testing. Existing guidelines, both in Europe and internationally, entail mostly therapeutic rather than molecular testing recommendations. This may reflect ambiguity among experts due to lack of evidence and also practical barriers in availability of the preferred molecular somatic screening and/or targeted treatments. This article reviews existing European recommendations regarding advanced/metastatic TC management with a special focus on molecular testing, and compares findings with real-world practice based on a recent survey involving TC experts from 18 European countries. Significant disparities are highlighted between theory and practice related to variable access to infrastructure, therapies and expertise, together with the insufficient availability of multidisciplinary tumour boards. In particular, practitioners' choice of what, how and when to test is shown to be influenced by the expertise of the available laboratory, the financing source and the existence of potential facilitators, such as clinical trial access. Overall, the need of a collaborative initiative among European stakeholders to develop standardised, accessible molecular genotyping approaches in TC is underscored.

RESUMO

INTRODUCTION: Adenoid cystic carcinoma of minor salivary glands (AdCCmSG) represents a 'rarity in the rarity,' posing a clinical challenge in lack of standardized, evidence-based recommendations. At present, AdCCmSG management is mostly translated from major salivary gland cancers (MSGCs). Ideally, AdCCmSG diagnostic-therapeutic workup should be discussed and carried out within a multidisciplinary, high-expertise setting, including pathologists, surgeons, radiation oncologists and medical oncologists. AREAS COVERED: The present review provides an overview of epidemiology and pathologic classification. Moreover, the most recent, clinically relevant updates in the treatment of AdCCmSG (Pubmed searches, specific guidelines) are critically discussed, aiming to a better understanding of this rare pathologic entity, potentially optimizing the care process, and offering a starting point for reflection on future therapeutic developments. EXPERT OPINION: The management of rare cancers is often hindered by limited data and clinical trials, lack of evidence-based guidelines, and hardly represented disease heterogeneity, which cannot be successfully tackled with a 'one-size-fits-all' approach. Our goal is to address these potential pitfalls, providing an easy-to-use, updated, multidisciplinary collection of expert opinions concerning AdCCmSG management as of today's clinical practice. We will also cover the most promising future perspectives, based on the potential therapeutic targets highlighted within AdCCmSG's molecular background.

RESUMO

Background: Breast cancer is the most frequent tumour worldwide, and the HR+/HER2- subtype is the most common. For this tumour type, endocrine therapy (ET) is the mainstay of treatment. The association of ET and CDK4/6 inhibitors (CDK4/6i) represents the gold standard for first-line or second-line therapies. However, the optimal therapeutic strategy after CDK4/6i progression is still a matter of debate, with several randomized clinical trials still ongoing. Patients and methods: This is an observational, prospective, real-world study including women with HR+/HER2- metastatic breast cancer progressing to palbociclib plus ET. Patients received either ET or chemotherapy (CT). The primary objective was the evaluation of efficacy of the different therapeutic strategies after palbociclib in terms of median progression-free survival 2. Secondary objectives were the activity of therapeutic strategies measured with the clinical benefit rate, evaluation of the parameters used for the treatment choice, and progression-free survival 1 related to palbociclib plus ET treatment. Results: Overall, 48 patients (median age 53, range 33-78 years) were included. The median progression-free survival 2 was of 5 months in the overall cohort (95% CI 4-48 months) with a statistically significant difference between the two therapeutic strategies adopted (ET versus CT, 10 months versus 5 months, respectively). Regarding secondary objectives, the clinical benefit rate was 55.2% in the CT cohort and 50% in ET. Moreover, women treated with CT had a greater number of visceral metastases and a shorter median progression-free survival 1 than patients who received ET. Conclusions: ET and CT represent two possible therapeutic alternatives for patients progressing on CDK4/6i plus ET. The choice is based on clinical parameters, with a potential preference for ET.

RESUMO

Introduction: In the multidisciplinary management of oligometastatic, persistent, or recurrent (MPR) ovarian cancer, radiotherapy (RT) is becoming a more and more worthwhile treatment to potentially improve the chronicity of the disease. Particle beam RT has proved to be effective in several gynecological malignancies, but so far no data are available for ovarian cancer. Material and Methods: This is a real-world, retrospective, bi-institutional, single-arm study aimed to assess the effectiveness and the safety of carbon ion RT (CIRT) in this setting. The co-first endpoints are 1-year and 2-year actuarial local control (LC) rates and the objective response rate (ORR) defined on a "per lesion" basis. The secondary endpoint was toxicity. Actuarial outcomes were evaluated using the Kaplan-Meier method while potential predictors were explored using the Log-rank test. Bi-variable logistic regression was employed in the analysis of factors predicting the complete response on a per-lesion basis. Results: 26 patients accounting for a total of 36 lesions underwent CIRT with a total median dose of 52.8 Gy[RBE] (range: 39-64 Gy[RBE]). Five patients received CIRT for re-irradiation. No concomitant systemic therapies were administered during CIRT. Within 12 months after the treatment, 17 lesions (47 %) achieved complete response while 18 (50 %) obtained a partial response with an ORR of 97 %. The achievement of a complete response is related to the dose per fraction (>4.2 Gy[RBE], p = 0.04) and total dose (>52,8 Gy[RBE], p = 0.05). The 1-year LC was 92 % and the 2-year LC was 83 %, according to the achievement of a CR (p = 0.007) and GTV ≤ 14 cm3 (p = 0.024). No grade > 3 toxicities were recorded both in naïve and re-irradiated patients. PARP-i and anti-VEGF seemed not to exacerbate the risk of severe toxicities. Conclusions: CIRT was effective and safe in MPR ovarian cancers, even in the case of re-irradiation. Largest cohort studies and longer follow-up are needed to confirm these data.

RESUMO

PURPOSE: The purpose of this study was to investigate the impact of the type of data capture on the time and help needed for collecting patient-reported outcomes as well as on the proportion of missing scores. METHODS: In a multinational prospective study, thyroid cancer patients from 17 countries completed a validated questionnaire measuring quality of life. Electronic data capture was compared to the paper-based approach using multivariate logistic regression. RESULTS: A total of 437 patients were included, of whom 13% used electronic data capture. The relation between data capture and time needed was modified by the emotional functioning of the patients. Those with clinical impairments in that respect needed more time to complete the questionnaire when they used electronic data capture compared to paper and pencil (ORadj 24.0; p = 0.006). This was not the case when patients had sub-threshold emotional problems (ORadj 1.9; p = 0.48). The odds of having the researcher reading the questions out (instead of the patient doing this themselves) (ORadj 0.1; p = 0.01) and of needing any help (ORadj 0.1; p = 0.01) were lower when electronic data capture was used. The proportion of missing scores was equivalent in both groups (ORadj 0.4, p = 0.42). CONCLUSIONS: The advantages of electronic data capture, such as real-time assessment and fewer data entry errors, may come at the price of more time required for data collection when the patients have mental health problems. As this is not uncommon in thyroid cancer, researchers need to choose the type of data capture wisely for their particular research question.

RESUMO

PURPOSE OF REVIEW: Anaplastic thyroid cancer (ATC) is a rare and deadly malignancy. There is a need to speed up and support clinical research. This review article focuses on the new molecules that have been developed for the treatment of this aggressive tumor. RECENT FINDINGS: Improvement in the knowledge of pathogenesis and genetics of ATC led to the development of a variety of new molecules that may be used to treat this disease. In summary, these molecules are proteasome inhibitors, Aurora kinase inhibitors, vascular targeting agents, and gene therapies. All these molecules demonstrated a potentially therapeutic activity in metastatic ATC. To date, the largest prospective randomized multicenter, open-label, trial was conducted with combretastatin-A4. SUMMARY: More efficient drugs need to be developed through multinational efforts.

RESUMO

INTRODUCTION: Conventional treatments for head and neck squamous cell cancer (HNSCC) are not completely effective and present several issues in terms of toxicity. Treatments available consist of surgery, chemoradiotherapy and biological agents. AREAS COVERED: Tyrosine-kinase inhibitors (TKIs) alone or in combination, already tested or currently under investigation, will be evaluated together with their time placement along the treatment as well as the disease setting where they were used. EXPERT OPINION: From the results of the main trials on TKIs, it emerges that these agents added to chemotherapy in recurrent/metastatic setting do not represent the best approach because of the major side effects, worsened by the complex characteristics of treated patients, and the lack of gain in terms of efficacy. Targeted agents could better exploit their activity in other settings, such as either before local regional treatment or immediately after to modulate biological effects induced by the treatment itself (surgery and/or radiation) and/or concurrently with radiation. Future research should also focus on irreversible pan-HER inhibitors, or combination agents able to overcome primary and acquired resistance, and on relevant biomarkers that would allow for a better therapeutic index of these molecules.
