RESUMO

Cancer of unknown primary site is a histologically confirmed cancer that manifests in advanced stage, with no identifiable primary site following standard diagnostic procedures. Patients are initially categorized based on the findings of the initial biopsy: adenocarcinoma, squamous-cell carcinoma, neuroendocrine carcinoma, and poorly differentiated carcinoma. Appropriate patient management requires understanding several clinical and pathological features that aid in identifying several subsets of patients with more responsive tumors (AU)

RESUMO

Purpose. While much progress has been made in the treatment of breast cancer, cardiac complications resulting from therapy remain a significant concern. Both anthracyclines and novel targeted agents can inflict cardiac damage. The present study aimed to evaluate the difference between what it is currently done and what standards of care should be used to minimizing and managing cardiac toxicity in breast cancer survivors. Methods. A two-round multicenter Delphi study was carried out. The panel consisted of 100 oncologists who were asked to define the elected therapies for breast cancer patients, the clinical definition and patterns of cancer drug-derived cardiac toxicity, and those protocols focused on early detection and monitoring of cardiovascular outcomes. Results. Experts agreed a more recent definition of cardiotoxicity. Around 38 % of patients with early-stage disease, and 51.3 % cases with advanced metastatic breast cancer had preexisting risk factors for cardiotoxicity. Among risk factors, cumulative dose of anthracycline ≥450 mg/m2 and its combination with other anticancer drugs, and a preexisting cardiovascular disease were considered the best predictors of cardiotoxicity. Echocardiography and radionuclide ventriculography have been the proposed methods for monitoring changes in cardiac structure and function. Breast cancer is generally treated with anthracyclines (80 %), so that the panel strongly stated about the need to plan a strategy to managing cardiotoxicity. A decline of left ventricular ejection fraction (LVEF) >10 %, to an LVEF value <53 % was suggested as a criterion for changing the dose schedule of anthracyclines, or suspending the treatment of chemotherapy plus trastuzumab until the normalization of the left ventricular function. The use of liposomal anthracyclines was strongly suggested as a treatment option for breast cancer patients. Conclusions. The present report is the first to produce a set of statements on the prevention, evaluation and monitoring of chemotherapy-induced cardiac toxicity in breast cancer patients (AU)

RESUMO

Chemotherapy and radiotherapy often result in reduced fertility in cancer patients. With increasing survival rates, fertility is an important quality-of-life concern for many young cancer patients. Around 70-75% of young cancer survivors are interested in parenthood but the numbers of patients who access fertility preservation techniques prior to treatment are significantly lower. Moreover, despite existing guidelines, healthcare professionals do not address fertility preservation issues adequately. There is a critical need for improvements in clinical care to ensure patients are well informed about infertility risks and fertility preservation options and to support them in their reproductive decision-making prior to cancer treatment (AU)

RESUMO

Bone metastases are common in many advanced solid tumours, being breast, prostate, thyroid, lung, and renal cancer the most prevalent. Bone metastases can produce skeletal-related events (SREs), defined as pathological fracture, spinal cord compression, need of bone irradiation or need of bone surgery, and hypercalcaemia. Patients with bone metastases experience pain, functional impairment and have a negative impact on their quality of life. Several imaging techniques are available for diagnosis of this disease. Bone-targeted therapies include zoledronic acid, a potent biphosfonate, and denosumab, an anti-RANKL monoclonal antibody. Both reduce the risk and/or delay the development of SREs in several types of tumours. Radium 233, an alpha-particle emitter, increases overall survival in patients with bone metastases from resistant castration prostate cancer. Multidisciplinary approach is essential and bone surgery and radiotherapy should be integrated in the treatment of bone metastases when necessary. This SEOM Guideline reviews bone metastases pathogenesis, clinical presentations, lab tests, imaging techniques for diagnosis and response assessment, bone-targeted agents, and local therapies, as radiation and surgery, and establishes recommendations for the management of patients with metastases to bone (AU)

RESUMO

PURPOSE: The primary aim of this trial was to assess the rate of pathologic complete responses (pCR) of doxorubicin/cyclophosphamide (AC) followed by bevacizumab/docetaxel (BT), as neoadjuvant therapy for breast cancer (BC). Furthermore, the association between biomarkers and the pCR was explored. METHODS: Patients with HER-negative operable stage II-III BC ≥ 2 cm were enrolled. Four cycles of AC (A 60 mg/m(2) and C 600 mg/m(2), every 3 weeks) followed by 4 cycles of BT (B 15 mg/kg and T 75 mg/m(2), every 3 weeks), were planned. A core-biopsy was performed for biological markers assessment. RESULTS: Seventy-two women were included. Forty-three (63 %) patients were hormone receptor-positive. Sixty-four (89 %) completed the planned treatment, and 66 evaluable patients underwent surgery (92 %): a pCR was achieved in 16 of them (24, 95 % CI 15-36 %). pCR was significantly higher in tumors hormone receptor-negative, and in those with Angiotensin II type 1 receptor (AGTR1) protein overexpression. The overall clinical response rate was 86 % (95 % CI 76-93 %), including 42 complete responses. No unexpected toxicities or treatment-related deaths were observed. CONCLUSION: This regimen showed a remarkable clinical and pathological activity: the suggested relation between pCR and AGTR1 overexpression should be confirmed in larger trials (AU)

RESUMO

OBJETIVO: Proporcionar estimadores de la eficiencia de esquemas oncológicos empleados en España. MÉTODOS: Se seleccionaron las publicaciones de ensayos clínicos en fase III usados para indicación de las terapias oncológicas de alto impacto empleadas para tratamiento de tumores sólidos en estadíos III-IV. Para cada esquema se calculó la relación coste-eficacia incremental (RCEI) respecto al comparador del ensayo, con la perspectiva del Sistema Nacional de Salud. El coste (€, 2012) farmacológico, en PVL, de cada esquema y comparador se estimó con las unidades de medicamento requeridas en cada administración (aprovechamiento máximo de viales) considerando la posología y el número de ciclos especificado en el ensayo para cada una de las ramas. La efectividad se expresó en meses de supervivencia global (SG) y/o supervivencia libre de progresión (SLP). RESULTADOS: Se analizaron 40 esquemas oncológicos para trece tumores metastásicos. La SG osciló entre 5,3 y 33,3 meses para las 34 terapias que incluían esa información, con valores de hazard ratio (HR) respecto a sus comparadores de 0,49 a 1,15. La SLP osciló entre 1,5 y 12,4 meses para las 39 terapias con este dato, con HR de 0,33 a 1,52. Los valores de RCEI oscilaron entre 2.142,57 €-60.996,37 €/mes de SG adicional y entre 2.102,54 €-661.845,27 €/mes de SLP adicional. CONCLUSIÓN: La dispersión y heterogeneidad de la supervivencia y RCEI estimadas, sugieren disparidad de criterios en la decisión de precio y financiación de las terapias, en España. Los continuos avances en terapias oncológicas parecen requerir reevaluaciones económicas de los medicamentos (AU)


OBJECTIVE: To provide estimates of the efficiency for chemotherapy strategies used in Spain. METHODS: Published reports of the phase-Ill clinical trials for chemotherapies used for the most prevalent solid tumours in Spain were retrieved. The incremental cost-effectiveness ratio (ICER) was calculated for each strategy compared to the control group in the clinical trial, with the National Health System perspective. The total cost (€, 2012) including only drug cost (ex-factory price) was estimated based on the total units of each drug required for administration (no vial wastage), with the dosification and number of cycles specified in the publication for each treatment arm. Effectiveness was measured as month of overall survival (OS) and/or month of progression free survival (PFS). RESULTS: A total of 40 chemotherapies for 13 different advanced or metastatic tumours were assessed. OS ranged from 5.3 to 33.3 months for the 34 therapies that included the information with hazard ratios (HR) values from 0.49 to 1.15 when compared with its control group. PFS ranged, from 39 therapies with these data, between 1.5 to 12.4 months, with HR from 0.33 to 1.52. ICERs were between €2,142.57 and €60,996.37 per each OS month gained, and from €2,102.54 to €661,845.27 per PFS month gained. CONCLUSION: The variety and heterogenicity of survival and ICERs results, suggest disparity of criteria in the price and reimbursement process of drugs in Spain. The continuous advances in oncology seem to require economic revaluations of drugs (AU)

RESUMO

PURPOSE: To determine which are the most sensitive tests, together with accommodative amplitude, to classify accommodative insufficiency (Al), we analyzed the relation between monocular estimated method (MEM) dynamic retinoscopy, monocular and binocular accommodative facility (MAF, BAF), and positive relative accommodation (PRA) with or without the presence of reduced amplitude of accommodation. METHODS: We studied 328 symptomatic patients who presented consecutively to an optometric clinic. From this sample, we selected the 41 patients who presented amplitude of accommodation at least 2 D below the minimum age-appropriate amplitude according to Hofstetter's formula: 15 - 0.25 x age. We also selected data from 40 consecutive subjects (control group) with no general binocular disorders and normal accommodative amplitudes. We studied the specificity and sensitivity of the four signs related with the accommodative insufficiency: high MEM dynamic retinoscopy, failing MAF and BAF with minus lenses of +/- 2 D flipper lenses, and low PRA. RESULTS: Using the standard deviation as the cutoff, the specificity values were MEM = 0.88, MAF = 1, BAF = 0.93, and PRA = 1. When using the mean value as the cutoff, the specificity diminished, fundamentally for MEM. The sensitivity for the 41 patients using standard deviation as the cutoff was MEM = 0.44, MAF = 0.34, BAF = 0.27, and PRA = 0.27, and when using the mean value as the cutoff the four, sensitivity values increased. CONCLUSIONS: According to the sensitivity results, with both cutoffs used, failing the +/- 2 D MAF test seems to be the sign that is most associated with the accommodative insufficiency.
