RESUMO

Arterial thromboembolism has been associated with cancer or its treatment. Unlike venous thromboembolism, the incidence and risk factors have not been extensively studied. Here, we investigated the incidence of arterial thromboembolic events (ATEs) in an institutional series of advanced urinary tract cancer (aUTC) treated with cytotoxic chemotherapy. The ATE definition included peripheral arterial embolism/thrombosis, ischemic stroke and coronary events. A total of 354 aUTC patients were analyzed. Most patients (95.2%) received platinum-based chemotherapy. A total of 12 patients (3.4%) suffered an ATE within a median time of 3.6 months from the start of chemotherapy. The most frequent ATE was ischemic stroke (n = 7). Two ATEs were fatal. The 6-month and 24-month incidence were 2.1% (95% confidence interval [CI]: 0.9-4.1) and 3.6% (95% CI: 1.9-6.2), respectively. Perioperative chemotherapy increased the risk for ATE by 5.55-fold. Tumors other than UTC and pure non-transitional cell carcinoma histology were also independent risk factors. No association with the type of chemotherapy was found. Overall, ATEs occur in 4.6% of aUTC patients treated with chemotherapy and represent a clinically relevant manifestation. Perioperative chemotherapy significantly increases the risk for ATE. The role of prophylaxis in high-risk groups should be prospectively studied.

RESUMO

BACKGROUND: The Hippo pathway is a developmental pathway recently discovered in Drosophila melanogaster; in mammals it normally controls organ development and wound healing. Hippo signaling is deregulated in breast cancer (BC). MST1/2 and LATS1/2 kinases are the upstream molecular elements of Hippo signaling which phosphorylate and regulate the two effectors of Hippo signaling, YAP1 and TAZ cotranscriptional activators. The two molecular effectors of the Hippo pathway facilitate their activity through TEAD transcription factors. Several molecular pathways with known oncogenic functions cross-talk with the Hippo pathway. METHODS: A systematic review studying the correlation of the Hippo pathway with BC tumorigenesis, prognosis, and treatment was performed. RESULTS: Recent literature highlights the critical role of Hippo signaling in a wide spectrum of biological mechanisms in BC. DISCUSSION: The Hippo pathway has a crucial position in BC molecular biology, cellular behavior, and response to treatment. Targeting the Hippo pathway could potentially improve the prognosis and outcome of BC patients.

RESUMO

Neoadjuvant Chemotherapy (NACT) followed by Interval Debulking Surgery (IDS) is an accepted frontline treatment in patients with advanced Epithelial Ovarian Cancer (EOC). Histopathologic assessment of tumor post NACT may provide a surrogate for response to treatment. The present study aims to characterize the pathological response and to examine its prognostic significance in these patients. Medical records of women with EOC treated in our institution from 2011 to 2016 were retrospectively identified. IDS specimens were reviewed by study pathologist and Chemotherapy Response Score (CRS), lymphocytic infiltration, necrosis and mitosis were assessed. 55 patients with EOC treated with NACT were identified and 48 had complete clinical and pathological data. Median age was 63 years. CRS assessed at omentum predicted PFS when adjusted for age, stage, debulking status (complete, optimal, suboptimal) and post IDS bevacizumab administration (mPFS CRS 1 vs 2 vs 3: 10.3-14-18.7 months 95% CI [7.4-15.7], [12.2-22.9], [13.5-31.3]). Presence of lymphocytic infiltration was associated with improved OS (log-rank test P = 0.015). Post IDS bevacizumab was associated with shorter PFS in patients with lymphocytic infiltration. BRCA status was known for 25 patients and presence of BRCA1/2 mutations was strongly correlated with lymphocytic infiltration (P = 0.011) but not CRS omentum (P = 0.926). Our study confirms the predictive value of CRS in EOC patients treated with NACT and IDS, but also demonstrates the prognostic significance of lymphocytic infiltration as well as its possible interaction with bevacizumab treatment.

RESUMO

BACKGROUND: Venous thromboembolic events (VTEs) frequently occur in cancer patients. Risk assessment models (RAMs) for cancer-associated thrombosis have been proposed. However, advanced urinary tract cancer (aUTC) was not adequately represented in these models. We studied the incidence of VTEs, the risk factors, and the applicability of recently described RAMs. PATIENTS AND METHODS: Data from 335 patients with aUTC treated with chemotherapy between April 1995 and September 2015 in a single institution were analyzed. RESULTS: A total of 95.2% received platinum-based first-line chemotherapy. Twenty-nine patients (8.7%) experienced VTEs. The 6-, 12-, and 24-month VTE incidence was 7.4% (95% confidence interval [CI], 4.8-10.6), 8.1% (95% CI, 5.4-11.5) and 9.4% (95% CI, 6.4-13.1), respectively. No significant association of VTE incidence with the Khorana risk score was observed. History of vascular event (VTE and/or arterial thromboembolic event) was significantly associated with the development of VTE. Patients with such history had a 6-, 12-, and 24-month VTE incidence of 16.2% (95% CI, 6.6-29.7), 19.2% (95% CI, 8.4-33.3), and 25.2% (95% CI, 12.5-40.1) compared to 6.2% (95% CI, 3.7-9.4), 6.6% (95% CI, 4.1-10), and 7.1% (95% CI, 4.4-10.6) of those who did not. The discriminatory ability of this factor adjusted for leucocyte count, sex, Eastern Cooperative Oncology Group performance status, and type of chemotherapy reached 0.79 (95% CI, 0.71-0.87) compared to the 0.58 (95% CI, 0.49-0.66) for the Khorana risk score. CONCLUSION: Development of tumor-specific algorithms for the risk of VTEs is advisable. Patients with aUTC and a history of vascular events are at high risk for VTE development, and prophylaxis should be prospectively studied in this group.

RESUMO

PURPOSE: Internet fake information, parapharmacy and counterfeit drugs are a market of hundreds of billion dollars. Misleading internet data decrease patients' compliance to medical care, promote use of questionable and detrimental practices, and jeopardize patient outcome. This is particularly harmful among cancer patients, especially when pain and nutritional aspects are considered. Provision of Web recommendations for the general audience (patients, relatives, general population) from official medical-providers might be useful to outweigh the detrimental internet information produced by non-medical providers. METHODS: 370 oncology and anesthesiology related societies were analyzed. Our objective was to evaluate the magnitude of web-recommendation for cancer cachexia and cancer pain for the general audience provided by official medical organizations' web sites at global level. RESULTS: Magnitude of web-recommendations at global level was surprisingly scant both for coverage and consistency. Seven official medical societies provided updated web-recommendation for cancer cachexia to their patients/family members, and 15 for cancer pain. Scantiness was unrelated by continent, developmental index, oncology tradition, economic-geographic area and society type scrutinized. CONCLUSIONS: Patients need expert advice when exposed to fake internet information largely dominated by paramedical market profits. In this era of "new media" the patients' net-education represents a new major educational challenge for medical societies.

RESUMO

INTRODUCTION: Cancer cachexia is a common associate of cancer and has a negative impact on both patients' quality of life and overall survival. Nonetheless its management remains suboptimal in clinical practice. Provision of medical recommendations in websites is of extreme importance for medical decision making and translating evidence into clinical practice. AIM OF THE STUDY: To scrutinize the magnitude, consistency and changes over time of cancer-cachexia recommendations for physicians on the Web among oncology related societies. Intercontinental, continental, national and socioeconomic variations were further analyzed. MATERIAL AND METHODS: Web identification of oncology related societies and prospective analyses of relative Web guideline recommendations for physicians on cancer-cachexia at different time-points. RESULTS: In June 2011, we scrutinized 144,000 Web pages. We identified 275 societies, of which 270 were eligible for analyses: 67 were international (African, American, Asian, European, Oceania and Intercontinental), 109 belonged to the top 10 countries with the highest development index and 94 pertained to 10 countries with a long lasting tradition in medical oncology. CONCLUSIONS: The magnitude of cancer cachexia recommendations for physicians on the Web at a global level was scant both for coverage and consistency, and at any time-point considered: 3.7% (10/270) in 2011 and 8.1% (22/270) in 2018. The proportion of societies giving evidence-based and updated recommendations for cancer cachexia for physicians was only 1.1% (3/270) in 2011 and 2.96% (8/270) in 2018. Continent, national highest developmental index, oncology tradition and economic-geographic areas were not found to influence Web guideline provision.

RESUMO

Background:Metastatic RCC (mRCC) treatment has been revolutionized with 11 approved targeted agents. We report patterns of practice, outcomes and pharmacoeconomic analyses after the introduction of targeted therapy. Patients and methods: CRISIS was a retrospective multicenter study of mRCCpatients who received targeted therapy . Results were related to the start of 1st-line therapy, with a cut off at 1 January 2011 in order to depict the impact of increased availability of effective options. Results: 164 patients, were included. 70.1% and 44.5% received 2nd and 3rd-line therapy, respectively. More patients were treated in 2nd-line after 1 January 2011. After a median follow-up of 55.1 months, median progression-free (PFS) and overall survival (OS) were 10.7 (95% confidence intervals [CI]: 8.3-13.7), 7.3 (95% CI: 5.1-8.6), 5.8 (95% CI: 3.8-7.8) and 34 (95% CI: 28.5-39.8), 22.4 (95% CI: 16-32.1), 18.3 (95% CI: 12.4-26.4) months for first, second and third line, respectively. Efficacy of sunitinib and pazopanib in 1st-line were similar. The mean total cost/patient was 35,012.2 Euros (standard deviation [SD]: 28,971.5). Conclusions: Our study confirms previous real-world data suggesting that continuing advances in the treatment of mRCC produce favorable outcomes in everyday practice. Pharmacoeconomic analyses are important for cost-effective utilization of emerging novel therapies.

RESUMO

BACKGROUND: Uterine sarcomas consist a heterogeneous group of mesenchymal gynecological malignancies with unclear therapeutic recommendations and unspecific but poor prognosis, since they usually metastasize and tend to recur very often, even in early stages. METHODS: We retrospectively analyzed all female patients with uterine sarcomas treated in our institution over the last 17 years. Clinico-pathological data, treatments and outcomes were recorded. Kaplan-Meier curves were plotted and time-to-event analyses were estimated using Cox regression. RESULTS: Data were retrieved from 61 women with a median age of 53 (range: 27-78) years, at diagnosis. Fifty-one patients were diagnosed with leiomyosarcoma (LMS), 3 with high grade endometrial stromal sarcoma (ESS), 5 with undifferentiated uterine sarcoma (UUS), 1 with Ewing sarcoma (ES) and 1 with Rhabdomyosarcoma (RS). 24 cases had stage I, 7 stage II, 14 stage III and 16 stage IV disease. Median disease-free survival (DFS) in adjuvant approach was 18.83 months, and median overall survival (OS) 31.07 months. High mitotic count (> 15 mitoses) was significantly associated with worse OS (P < 0.001) and worse DFS (P = 0.028). CONCLUSIONS: Mitotic count appears to be independent prognostic factor while further insights are needed to improve adjuvant and palliative treatment of uterine sarcomas.

RESUMO

Targeting genomic alterations, such as epidermal growth factor receptor (EGFR) mutations and anaplastic lymphoma kinase (ALK) gene rearrangements, have radically changed the treatment of patients with non-small cell lung cancer (NSCLC). In the case of ALK-rearranged gene, subsequent rapid development of effective genotype-directed therapies with ALK tyrosine kinase inhibitors (TKIs) triggered major advances in the personalized molecularly based approach of NSCLC. Crizotinib was the first-in-class ALK TKI with proven superiority over standard platinum-based chemotherapy for the 1st-line therapy of ALK-rearranged NSCLC patients. However, the acquired resistance to crizotinib and its diminished efficacy to the central nervous system (CNS) relapse led to the development of several novel ALK inhibitors, more potent and with different selectivity compared to crizotinib. To date, four ALK TKIs, crizotinib, ceritinib, alectinib and brigatinib have received approval from the Food and Drug Administration (FDA) and/or the European Medicines Agency (EMA) and even more agents are currently under investigation for the treatment of ALK-rearranged NSCLC. However, the optimal frontline approach and the exact sequence of ALK inhibitors are still under consideration. Recently announced results of phase III trials recognized higher efficacy of alectinib compared to crizotinib in first-line setting, even in patients with CNS involvement. In this review, we will discuss the current knowledge regarding the biology of the ALK-positive NSCLC, the available therapeutic inhibitors and we will focus on the raised issues from their use in clinical practise.

RESUMO

Mechanisms of tumor immune surveillance and immune escape have been recently elucidated and led to the development of a new therapeutic field in oncology, that of immunotherapy. Immunotherapy aims to reactivate the immune system against cancer. Neoplasias like non-small cell lung cancer (NSCLC) are of particular interest and clinical studies with immunotherapeutic agents have shown significant survival benefit. Several agents have gained corresponding regulatory approvals. In particular, nivolumab, pembrolizumab and atezolizumab have been approved for second-line treatment of NSCLC, pembrolizumab is the only immune checkpoint inhibitor that has been approved in the first-line treatment and durvalumab is approved in the locally advanced disease. In this review, we aim to present the implementation of immunotherapy in the treatment of advanced NSCLC. We will discuss not only the approved regimens but also the future perspectives, the serious adverse events such as hyperprogression and the possible predictive markers that will aid the selection of the patients that will benefit from immunotherapy.

RESUMO

BACKGROUND: Cancer cachexia is a common associate of cancer and has a negative impact on patients' survival. Nonetheless, cancer cachexia assessment and management are frequently less than satisfactory in daily practice. AIM: To scrutinise global cancer cachexia awareness and relative web guideline implementation among oncology societies. METHODS: Systematical identification of scientific and policymaker oncology societies and their guideline implementation on cancer cachexia. Assessment of the general level of awareness on cancer cachexia and evaluation of intercontinental and national variations on guideline implementation. RESULTS: 144,000 web pages were scrutinised, and 275 oncology societies identified covering a large array of oncology setting (educational/clinical/research/policymaker); 71 were international (African, American, Asian, European, Oceania and Intercontinental), 110 belonged to the top 10 countries with the highest development index and 94 pertained to 10 countries with a long lasting tradition in medical oncology (not included in the top 10 high developed countries). Overall, only 10/275 web sites provided guidelines; six of them (2.2%) provided guidelines for physicians and four (0.7%) for patients. Half of the guidelines (4/10) were outdated. All guidelines for physicians reported references, while only one of the recommendations for patients reported references to support its sentences. CONCLUSIONS: Cancer cachexia global awareness appears extremely low; guideline implementation on the web was inconsistent for any category analysed (nation vs continent vs international vs society type vs physician vs patient oriented) and for updating.
