RESUMO

In cancer, a patient is considered a survivor from the time of initial diagnosis until the end of life. With improvements in early diagnosis and treatment, the number of cancer survivors (CS) has grown considerably and includes: (1) Patients cured and free from cancer who may be at risk of late-onset cancer therapy-related cardiovascular toxicity (CTR-CVT); (2) Patients with long-term control of not-curable cancers in whom CTR-CVT may need to be addressed. This paper highlights the importance of the cancer care continuum, of a patient-centered approach and of a prevention-oriented policy. The ultimate goal is a personalized care of CS, achievable only through a multidisciplinary-guided survivorship care plan, one that replaces the fragmented management of current healthcare systems. Collaboration between oncologists and cardiologists is the pillar of a framework in which primary care providers and other specialists must be engaged and in which familial, social and environmental factors are also taken into account.

RESUMO

HER2-low and ultra-low breast cancer (BC) have been recently proposed as new subcategories of HER2 BC, supporting a re-consideration of immunohistochemical negative scores of 0, 1+ and the 2+/in situ hybridization (ISH) negative phenotype. In the present review, we outline the criteria needed to exactly distinguish HER2-low and ultra-low BC. Recent clinical trials have demonstrated significant clinical benefits of novel HER2 directing antibody-drug conjugates (ADCs) in treating these groups of tumors. In particular, trastuzumab-deruxtecan (T-Dxd), a HER2-directing ADC, has been recently approved by the US Food and Drug Administration as the first targeted therapy to treat HER2-low BC. Furthermore, ongoing trials, such as the DESTINY-Breast06 trial, are currently evaluating ADCs in patients with HER2-ultra low BC. Finally, we hope that new guidelines may help to codify HER2-low and ultra-low BC, increasing our knowledge of tumor biology and improving a targetable new therapeutical treatment.

RESUMO

INTRODUCTION: Standard treatment of newly diagnosed, advanced ovarian carcinoma (OC) consists of cytoreductive surgery followed by platinum-based chemotherapy with or without bevacizumab. Maintenance therapy with PARP inhibitors and olaparib-bevacizumab has recently shown to significantly improve progression-free survival in the first-line setting. Some practical aspects of maintenance therapy, however, are still poorly defined. AIM OF THE STUDY: To provide guidance to clinicians in the selection of maintenance therapy for newly diagnosed, advanced ovarian carcinoma. METHODS: A board of six gynecologic oncologists with expertise in the treatment of OC in Italy convened to address issues related to the new options for maintenance treatment. Based on scientific evidences, the board produced practice-oriented statements. Consensus was reached via a modified Delphi study that involved a panel of 22 experts from across Italy. RESULTS: Twenty-seven evidence- and consensus-based statements are presented, covering the following areas of interest: use of biomarkers (BRCA mutations and presence of homologous recombination deficiency); timing and outcomes of surgery; selection of patients eligible for bevacizumab; definition of response to treatment; toxicity and contraindications; evidence of synergy of bevacizumab plus PARP inhibitor. Two treatment algorithms are also included, for selecting maintenance therapy based on timing and outcomes of surgery, response to platinum-based chemotherapy and biomarker status. A score for the assessment of response to chemotherapy is proposed, but its validation is ongoing. CONCLUSIONS: We provide here consensus statements and treatment algorithms to guide clinicians in the selection of appropriate and personalized maintenance therapy in the first-line setting of advanced OC management.

RESUMO

Background: Lung neuroendocrine neoplasms (NENs) are rare malignancies developed from bronchial mucosa. Because of its rarity and complex histopathology, there is limited data on the role of chemotherapy in this subset of tumors. Few studies regarding the treatment of poorly differentiated lung NENs, known as neuroendocrine carcinomas (NECs), are available and many limits are detectable as heterogeneity of tumor samples including different origins and different clinical behaviors, moreover, no evidence of therapeutic advances have been achieved along the last thirty years. Method: We performed a retrospective analysis of 70 patients affected by poorly differentiated lung NECs: half of patients underwent a first line therapy with a combination of cisplatin plus etoposide; the remaining patients receiving carboplatin instead of cisplatin, plus etoposide. Results: In our analysis, the outcomes of patients treated with either cisplatin or carboplatin schedule are similar in terms of ORR (44% versus 33%), DCR (75% versus 70%), PFS (6.0 versus 5.0 months) and OS (13.0 versus 10 months). Median number of chemotherapy cycles was 4 (range 1-8). The 18% of patients required a dose reduction. Main toxicities reported were hematological (70.5%), gastrointestinal (26.5%) and fatigue (18%). Conclusion: Survival rate in our study suggests that high grade lung NENs are characterized by an aggressive behavior and a poor prognosis, despite the treatment with platinum/etoposide according to available data. Clinical results of present study contribute to strengthen available data on the usefulness of platinum/etoposide regimen in the treatment of poorly differentiated lung NENs.

RESUMO

BACKGROUND: In real-world practice, eribulin mesylate provides significant survival benefit, with a manageable safety profile in heavily pretreated patients with metastatic breast cancer (MBC). METHODS: In this prospective, open-label, multicentre, observational study we evaluated the effectiveness and tolerability of eribulin as third-line treatment in a homogeneous population. The primary endpoints were the safety profile and response in metastatic sites; secondary endpoints included the response in different subtypes, overall response rate (ORR), progression-free survival (PFS) and overall survival (OS). RESULTS: From 2013 to 2016, 118 women were treated in 21 Sicilian institutions; the median age was 58 years (range 29-79), with 69% of patients under 65. The median cycles of eribulin were 5.5 (range 1-26). The most common adverse event was neutropenia (9.3%, 3 cases of grade 3, 4 of grade 4); only 1 case of QT prolongation was reported. Eribulin was effective in controlling metastatic disease in all sites, and it achieved the highest ORR in brain (16%) and liver (14.9%). Median OS was 31.8 months (95% CI 27.9-34.4) and median PFS 5.5 months (95% CI 4.2-6.6). PFS was 5.2 months (95% CI 2.8-8.4) in patients with triple-negative subtype. Median PFS was longer in patients over 65 years (6.1 months, 95% CI 4.4-8.3). In patients who had visceral metastases PFS was 5.5 months (95% CI 95% 3.5-6.6) and OS 33.9 months (95% CI 29.8-40.8). CONCLUSIONS: Eribulin as third-line treatment shows an acceptable safety profile and a substantial antitumour activity in the treatment of MBC, even in elderly patients and in those with visceral disease.

RESUMO

BACKGROUND: Herein, we report a complete response after whole brain radiotherapy (WBRT) and concomitant T-DM1 in a patient with HER2-positive metastatic breast cancer (MBC) and extensive brain and leptomeningeal involvement. CASE PRESENTATION: A 46 years old Caucasian woman with HER2-positive MBC and no baseline CNS involvement, started in August 2015 1st line therapy with Pertuzumab-Trastuzumab-Docetaxel, with partial response. However, in April 2016 the patient eventually progressed with emergence of brain and leptomeningeal metastases. Hence, she started in May 2016 2nd line therapy with T-DM1 and concomitant WBRT, with complete response (CR) after 3 courses of therapy, with complete resolution of neurological symptoms and no relevant toxicities. The CR is lasting over 13 months and the patient is out of corticosteroid use. CONCLUSIONS: To the best of our knowledge, this is the first case reporting interesting antitumor activity of T-DM1 and concomitant WBRT in both brain and leptomeningeal metastases, with a favorable safety profile and prolonged extracranial disease control. Further prospective studies should confirm these findings.

RESUMO

Background: Triple Negative Breast Cancer (TNBC) represents a heterogeneous group of tumors with poor prognosis owing to aggressive tumor biology and lack of targeted therapies. No clear prognostic biomarkers have been identified to date for this subgroup. Materials and Methods: In this retrospective study we evaluated the prognostic role of 4 different molecular determinants, including androgen receptor (AR), E-cadherin (CDH1), Ki67 index, and basal cytokeratins (CKs) 5/6, in a cohort of 99 patients with TNBC. All patients received neo/adjuvant chemotherapy (mostly anthracycline/taxane-based). Immunohistochemistry (IHC) was performed in formalin-fixed paraffin-embedded primary tumor samples. CDH1 expression was considered positive as ≥ 30% of the membrane cells staining. AR positivity was defined as > 10% of positive tumor cells. High Ki67 was defined as ≥20% positive tumor cells. CK5/6 expression was judged positive if the score was ≥1. Results: The absence of AR expression was significantly associated with highly undifferentiated tumors. Univariate analyses showed that lack of expression of CDH1, tumor size and nodal status were significantly correlated with worse RFS and OS (p< 0.05). AR expression and low Ki67 showed a trend towards better RFS and OS. Patients with absent CK5/6 expression in univariate and multivariate analyses had poorer RFS (p=0.02 and p=0.002, respectively) and OS (p=0.05 and p=0.02, respectively). Multivariate analysis showed an independent association between CDH1 expression and better RFS and OS (p< 0.05) beyond tumor size, nodal status, and grade. The Kaplan-Meier curves showed that patients with AR and CDH1 negative expression and high Ki-67 levels have a significant correlation with poor outcome. Conclusions: Our study supports the use of IHC expression of AR, CDH1, Ki67, and CK5/6 as prognostic markers in TNBCs and suggests a link between their expression and prognosis and may help to stratify TNBC patients in different prognostic classes.

RESUMO

INTRODUCTION: During the last few years, the therapeutic armamentarium of castration resistant prostate cancer (mCRPC) has been enriched with the introduction of new effective therapies with proved survival benefit and quality of life gain, including cabazitaxel, abiraterone, enzalutamide, and Radium-223. Areas covered: Bone metastases represent a substantial cause of morbidity in mCRPC with a high rate of related skeletal events (SREs). In case of multifocal pain due to diffuse osteoblastic metastases, treatment with bone-targeting radiopharmaceutical agents can provide palliation from pain. Radium-223, a calcium-mimetic, is the first α-particle emitting radiopharmaceutical that prolonged overall survival, delayed symptomatic skeletal events and improved quality of life in mCRPC. Expert opinion: In this therapeutic scenario, no clear evidences support the best way to sequence these available agents and there is an urgent need for prospective studies to define it. 223Ra is a firmly established therapeutic option in CRPC with symptomatic bone metastases and no visceral/bulky nodal involvement, with an undeniable advantage over new hormonal agents, given its peculiar mechanism of action. Current ongoing randomized clinical trials will clarify the optimal use of this effective therapy in the therapeutic armamentarium of CRPC either alone or combined with other new approved agents and whether there is a role in patients with asymptomatic disease.

RESUMO

Epidermal Growth Factor Receptor (EGFR) mutated Non Small Cell Lung Cancers (NSCLCs) are a molecularly subgroup of patients with peculiar clinic-pathological characteristics. Previous studies have suggested a possible interaction between oncogene status and metastatic behavior in non squamous NSCLCs with conflicting results. The aim of this study was to compare the different metastatic patterns, at baseline and during the course of the disease, in a cohort of 137 Caucasian patients with non-squamous NSCLC according to the EGFR mutational status and survival differences according to the different metastatic behavior. We observed unique metastatic distributions between EGFR-mutated and EGFR wild type non-squamous NSCLCs. These data support the hypothesis that tumor bio-molecular characteristics and genotype may influence the metastatic process in NSCLC and might help the development of enrichment strategies for tumor genotyping in these tumors, especially in the presence of limited tissue availability.

RESUMO

During the last decade the therapeutic landscape of Non Small Cell Lung Cancer (NSCLC) has profoundly changed with the identification of actionable genetic alterations that defined molecularly selected subgroups of patients with specific clinic-pathological characteristics and increased sensitivity to specific targeted agents. The presence of ROS1 rearrangements defines a small subgroup of lung adenocarcinomas (∼1-2%) with peculiar clinic-pathological characteristics and increased sensitivity to Crizotinib. It has been reported that ROS1-tranlslocated NSCLCs may also respond well to Pemetrexed-based chemotherapy. Moreover, patients with oncogene-addicted NSCLC may present peculiar pattern of metastatization and, in some instances, are associated with unusual site of metastases. Herein, we present a case of a young woman with bilateral ovarian metastases from a ROS1-positive adenocarcinoma of the lung with a lengthy progression-free survival on Pemetrexed-containing chemotherapy.

RESUMO

Neoadjuvant therapy is a well-established approach for the treatment of locally advanced or inflammatory breast cancer (BC) and has been increasingly used in recent years not only as a management strategy but also as a research tool. Recently, nanoparticle albumin-bound paclitaxel (nab-paclitaxel)/trastuzumab combinations have been associated with promising activity in different clinical settings. In the present case, we report a complete pathological response after neoadjuvant treatment with the trastuzumab/nab-paclitaxel combination in a locally advanced human epidermal growth factor receptor 2 (HER2)-positive BC patient, with a good toxicity profile. This combination may represent a valid therapeutic option in the neoadjuvant therapy for HER2-positive locally advanced BC.

RESUMO

INTRODUCTION: ALK rearranged Non Small Cell Lung Cancers (NSCLCs) represent a distinct subgroup of patients with peculiar clinic-pathological features. These patients exhibit dramatic responses when treated with the ALK tyrosine kinase inhibitor Crizotinib, albeit Central Nervous System (CNS) activity is much less impressive than that observed against extracranial lesions. CNS involvement has become increasingly observed in these patients, given their prolonged survival. Several novel generation ALK inhibitors have been developing to increase CNS penetration and to provide more complete ALK inhibition.. AREAS COVERED: The CNS activity of Crizotinib and novel generation ALK inhibitors will be summarized in this review, evaluating the strengths and weaknesses of the therapeutic strategies developed to date in this specific subgroup of NSCLCs with a look towards the future. Expert commentary: In the next few years, the results of ongoing comparative head-to-head trials will provide the definitive conclusions on the optimal treatment sequence in ALK-rearranged NSCLCs. Moreover, ongoing clinical trials with novel-generation ALK inhibitors will produce more evidences on the best approach in the growing number of ALK-positive NSCLCs with CNS involvement.

RESUMO

The discovery of Epidermal Growth Factor Receptor (EGFR) mutations in Non Small Cell Lung Cancer (NSCLC) launched the era of personalized medicine in advanced NSCLC, leading to a dramatic shift in the therapeutic landscape of this disease. After ten years from the individuation of activating mutations in the tyrosine kinase domain of the EGFR in NSCLC patients responding to the EGFR tyrosine kinase inhibitor (TKI) Gefitinib, several progresses have been done and first line treatment with EGFR TKIs is a firmly established option in advanced EGFR-mutated NSCLC patients. During the last decade, different EGFR TKIs have been developed and three inhibitors have been approved so far in these selected patients. However, despite great breakthroughs have been made, treatment of these molecularly selected patients poses novel therapeutic challenges, such as emerging of acquired resistance, brain metastases development or the need to translate these treatments in earlier clinical settings, such as adjuvant therapy. The aim of this paper is to provide a comprehensive review of the major progresses reported so far in the EGFR inhibition in this molecularly-selected subgroup of NSCLC patients, from the early successes with first generation EGFR TKIs, Erlotinib and Gefitinib, to the novel irreversible and mutant-selective inhibitors and ultimately the emerging challenges that we, in the next future, are called to deal with.

RESUMO

BACKGROUND: TNBC is an aggressive subset of breast cancer (BC) without specific target therapy. METHODS: This observational, retrospective study included 45 cases of TNBC. The aim of this study was to evaluate the expression of the AR, E-cadherin and Ki-67 in relation to histological type, time to relapse and overall survival (OS). Immunohistochemistry (IHC) was carried out on formalin-fixed paraffin-embedded tumor samples obtained from patients defined TNBC. RESULTS: The AR was positive (IHC >10%) in 26.6%. E-cadherin (CDH1) expression was considered positive if the score was ≥ 2. This expression was negative in 53.3% cases. The Ki-67 index was ≥ 20% in 37.7%. Univariate analyses showed that AR, CDH1 and Ki-67 are significantly associated with OS. Multivariate analysis showed that AR and Ki-67 expression are independent variables associated with OS. The statistical analysis showed that patients with AR negative and Ki-67 positive expression have a significant correlation with poor outcome. CONCLUSIONS: Our data suggest that the combination of AR and E-cadherin expression as well as Ki-67 status might be useful prognostic markers in TNBC. Hence, these molecular determinants could play an interesting role to classify subgroups of TNBC.

RESUMO

Brain metastases (BMs) represent a major issue in clinical practice and are associated with a significant worsening of patient's quality of life and, often, a dismal prognosis. Breast cancer (BC) is the second most common solid malignancy that metastasizes to the central nervous system. Incidence of BM varies according to the tumor subtype, with higher rates in patients with epidermal growth factor receptor 2 (HER2) overexpression and in triple negative breast cancers. The incidence of BM in HER2-positive BC patients has increased as a consequence of the success of trastuzumab-based therapy. BM represents an emerging unmet medical need and no specific treatment options exist because, until recently, nearly all randomized clinical trials in metastatic breast cancer (MBC) excluded such patients. Therefore, novel approaches in this setting are eagerly awaited. Herein, we report a lengthy progression-free survival with the combination trastuzumab/nanoparticle albumin-bound (nab)-paclitaxel in a heavily pretreated HER2-positive BC patient with BM. The long-term disease stabilization reported in the present case (>13 months) is of note for several reasons. First, the nab-paclitaxel plus trastuzumab combination, despite several previous lines of treatment, some of which were associated with known activity on BM, was the first systemic therapy not associated with central nervous system recurrence, avoiding recourse to additional locoregional treatments. Moreover, this combination was associated with long extracranial stabilization with minimal toxicity. The remarkably lengthy progression-free survival reported in our case with the nab-paclitaxel plus trastuzumab combination further confirms the efficacy and the favorable toxicity profile of this promising schedule that showed intriguing results in two phase II studies in first-line MBC and suggests a possible activity on BM. In conclusion, weekly nab-paclitaxel plus trastuzumab may represent a valuable option in the treatment of HER2-positive MBC with BM after radiotherapy and is effective and associated with a good toxicity profile, even in heavily pretreated patients.
