Akinetopsia (visual motion blindness) associated with brain metastases: a case report.

Akinetopsia is a rare neurological syndrome characterized by an impaired perception of movement, often resulting from brain damage due to ischemia, epilepsy, or medication. It is also known as visual motion blindness, and patients with this condition are unable to perceive motion normally even with perfect visual acuity. This report aims to present a case of a patient in their late 40 s who developed akinetopsia and also an impairment in movement perception of objects without emitting sounds, after experiencing a late relapse of breast cancer with the occurrence of multiple brain metastases. The patient also experienced visual hallucinations, night terrors, and difficulty forming anterograde memory. Neuroimaging with MRI revealed severe brain damage, especially in the middle temporal area of the visual cortex. Akinetopsia is a rare phenomenon, and this is the first known case of its association with brain metastases.

Use of artificial intelligence to predict response to neoadjuvant chemotherapy in breast cancer

:Breast cancer is the object of thousands of studies worldwide. Nevertheless, few tools are available to corroborate prediction of response to neoadjuvant chemotherapy. Artificial intelligence is being researched for its potential utility in several fields of knowledge, including oncology. The development of a standardized Artificial intelligence-based predictive model for patients with breast cancer may help make clinical management more personalized and effective. We aimed to apply Artificial intelligence models to predict the response to neoadjuvant chemotherapy based solely on clinical and pathological data. Methods: Medical records of 130 patients treated with neoadjuvant chemotherapy were reviewed and divided into two groups: 90 samples to train the network and 40 samples to perform prospective testingand validate the results obtained by the Artificial intelligence method. Results: Using clinicopathologic data alone, the artificial neural network was able to correctly predict pathologic complete response in 83.3% of the cases. It also correctly predicted 95.6% of locoregional recurrence, as well as correctly determined whether patients were alive or dead at a given time point in 90% of the time. To date, no published research has used clinicopathologic data to predict the response to neoadjuvant chemotherapy in patients with breast cancer, thus highlighting the importance of the present study. Conclusions: Artificial neural network may become an interesting tool for predicting response to neoadjuvant chemotherapy, locoregional recurrence, systemic disease progression, and survival in patients with breast cancer (AU)

Health-Related Quality of Life Outcomes in Head and Neck Cancer: Results From a Prospective, Real-World Data Study With Brazilian Patients Treated With Intensity Modulated Radiation Therapy, Conformal and Conventional Radiation Techniques.

PURPOSE: To compare global health-related quality of life (HRQoL) and overall survival (OS) in patients with head and neck cancer treated with intensity modulated radiation therapy (IMRT), conformal radiation therapy (3DCRT) or conventional radiation therapy (2DRT). METHODS AND MATERIALS: In this real-world, multi-institutional and prospective study, HRQoL outcomes were assessed using the European Organisation for Research and Treatment of Cancer Quality-of-life Questionnaire Core 30 (EORTC QLQ-C30) and European Organisation for Research and Treatment of Cancer Quality-of-life Questionnaire Head and Neck 43 (H&N43) questionnaires. Item response theory was used to generate a global HRQoL score, based on the 71 questions from both forms. The effect of treatment modality on HRQoL was studied using multivariate regression analyses. Survival was estimated using the Kaplan-Meyer method, and groups were compared by the log-rank test. RESULTS: Five hundred and seventy patients from 13 institutions were included. Median follow-up was 12.2 months. Concerning the radiation technique, 29.5% of the patients were treated with 2DRT, 43.7% received 3DCRT, and 26.8% were treated with IMRT. A higher proportion of patients receiving 2DRT had a treatment interruption of more than 5 days (69% vs 50.2% for 3DCRT and 42.5% for IMRT). IMRT had a statistically significant positive effect on HRQoL compared with 3DCRT (ß= 2.627, standard error = 0.804, P = .001) and 2DRT had a statistically significant negative effect compared with 3DCRT (ß= -5.075, standard error = 0.926, P < .001). Patients receiving 2DRT presented a worse OS (P = .01). There were no differences in OS when IMRT was compared with 3DCRT. CONCLUSIONS: IMRT provided better HRQoL than 3DCRT, which provided better HRQoL than 2DRT. Patients receiving 2DRT presented a worse OS, which might be related to more frequent treatment interruptions.

Evaluation of clinical and pathological response factors to neoadjuvant chemotherapy in breast cancer patients

Objectives: To evaluate breast cancer (BC) patients treated with neoadjuvant chemotherapy (NACT) and to analyze clinicopathological features correlating with pathological complete response (PCR) and survival outcomes. Methods: Observational, descriptive, and retrospective study. The medical records of BC patients who underwent NACT were reviewed and analyzed using the Statistical Package for the Social Sciences (SPSS), version 20.0. Results: Of the 176 BC patints who underwent NACT, 62 patients (35.2%) achieved PCR. The PCR rate was 22% (n = 2) for luminal A, 15% (n = 9) for luminal B/HER2-negative, 45.5% (n = 15) for luminal B/ HER2-positive, 50% (n = 14) for non-luminal/HER2-positive, and 47.8% (n = 22) for triple-negative (p = 0.01). Histological grade, estrogen receptor (ER) expression, progesterone receptor (PR) expression, and HER2 status were significantly associated with PCR (p = 0.022, p = 0.01, p = 0.01, and p = 0.02, respectively). The median follow-up was 35.9 months, the estimated 5-year disease-free survival (DFS) was 96.7% in the PCR group and 83.2% in the non-PCR group (p = 0.05). The estimated 5-year overall survival (OS) was 95.5% in the PCR group and 69.1% in the non-PCR group (p = 0.017). Overall, 11 patients (6.25%) presented with locoregional recurrence (LRR), one (1.6%) in the PCR group and 10 (8.8%) in the non-PCR group (p = 0.10). Conclusion: We observed higher PCR rates in triple-negative and HER2-positive molecular subtypes. DFS and OS were significantly better in patients who achieved PCR, regardless of clinicopathological features. We also observed lower rates of LRR in the population that reached PCR.

Introdução: A presença de um nutricionista no setor de radioterapia objetiva a recuperação e a manutenção do estado nutricional dos pacientes. Objetivo: Comparar os resultados do aconselhamento nutricional diário com o aconselhamento nutricional semanal em pacientes com câncer de cabeça, pescoço e esôfago em tratamento radioterápico. Método: Foram selecionados 29 pacientes para o estudo e separados aleatoriamente em dois grupos. O grupo intervenção recebeu aconselhamento nutricional diariamente. O grupo padrão recebeu aconselhamento nutricional semanalmente. De ambos os grupos, foram aferidos peso corporal, circunferência braquial ou de panturrilha, avaliação subjetiva global produzida pelo próprio paciente (ASG-PPP) e cálculo do recordatório alimentar diário. Resultados: A maioria dos participantes era do sexo masculino (80%), com média de idade de 62,7 ± 26 anos. A terapia nutricional oral foi necessária para 48% dos indivíduos e, ao final do tratamento, 60% estavam em uso de nutrição enteral. A perda de peso média no grupo intervenção foi de 1,89 ± 2,58 Kg comparada à perda média de peso no grupo padrão de 9,92 ± 6,68 Kg (p=0,017). Metade dos pacientes do grupo intervenção, que iniciaram o tratamento categorizados pela ASG-PPP em A, finalizou o tratamento nessa mesma categoria (41,7%). Mais de 40% dos pacientes do grupo intervenção alcançaram as necessidades calóricas durante cinco semanas do tratamento. Conclusão: Encontraram-se resultados significativos para menor perda de peso em pacientes com aconselhamento nutricional diário que podem futuramente ser precursores de diretrizes que orientem e direcionem profissionais a condutas específicas aos pacientes com esse perfil.

Introduction: The presence of a nutritionist in the radiotherapy sector intends to recover and maintain the nutritional status of the patients. Objective: To compare the results of daily nutritional counseling with weekly nutritional advising for patients with head, neck and esophagus cancer in radiotherapy treatment. Method: 29 patients were assigned to the study and randomly divided into two groups. The intervention group received nutritional advice daily. The standard group received weekly nutritional counseling. For both groups, body weight, calf or calf circumference, global subjective evaluation produced by the patient (ASG-PPP) and calculation of the daily dietary recall were measured. Results: The majority of the participants were male (80%), mean age 62.7 ± 26 years. Oral nutrition therapy was required treatment 60% were in use of enteral nutrition. The mean weight loss in the intervention group was 1.89 ± 2.58 kg compared to the mean weight loss in the standard group of 9.92 ± 6.68 kg (p <0.001). Half of the patients in the intervention group who began treatment categorized by ASG-PPP in A, finished treatment in the same category (41.7%). More than 40% of patients in the intervention group achieved caloric needs during five weeks of treatment. Conclusion: This study found significant results for lower weight loss in patients with daily nutritional counseling. These results may in the future be precursors of guidelines that steer and direct professionals to specific conducts to patients with this profile.

Expression of PD-L1 in cervical carcinoma and its impact on survival associated with T-cell infiltration and FoxP3 expression.

Background: The PD-1/PD-L1 signaling axis is currently the most elucidated mechanism for tumor evasion of T-cell-mediated immunity. Nevertheless, few data are available regarding its impact on cervical cancer and the relationship with lymphocytic infiltrates. Methods: A retrospective assessment of all cases of cervical neoplasia treated in Caxias do Sul General Hospital, Brazil, between 2012 and 2016 was performed. Clinical and pathological data were collected from electronic records and analyzed. Original slides were independently reviewed by three pathologists to confirm diagnoses and to assess the immunohistochemical expression of PD-L1 and FoxP3 in tumor cells and lymphocytic infiltrates. Results: PD-L1 staining was present in 32.2% of the 59 cervical samples. Median overall survival time of the PD-L1-negative group was 47.8 months, a time point not yet reached by the PD-L1-positive group (p=0.968). Median progression-free survival was 24.3 months for PD-L1-negative and 11.5 months for PD-L1-positive patients (p=0.263). PD-L1 staining was found in 27.1% of the lymphocytic infiltrates, and survival analysis revealed no difference between PD-L1-positive and PD-L1-negative samples. There was no impact on survival related to FoxP3 staining in neither tumor samples nor lymphocytic infiltrates. Conclusion: Although the median progression-free survival times differed, the difference was not statistically significant. Our study corroborates the rationale that PD-L1 expression in cervical neoplasms has no impact on survival. PD-L1 expression in peritumoral lymphocytes revealed no impact on infiltration volume nor survival. Keywords: uterine cervical neoplasms, tumor-infiltrating lymphocytes, cancer, tumor microenvironment, survival.

Analysis of time interval between breast cancer diagnosis and treatment / Análise do tempo decorrido entre diagnóstico e tratamento do câncer de mama

Introduction: Breast cancer has a good prognosis when treated early. However, the mortality rate in Brazil is still high. The time interval between radiological suspicion and diagnosis/treatment impacts the survival. Methods: This is a retrospective crosssectional study that assessed patients treated at a reference center, with abnormal breast imaging findings and subsequent confirmation of breast cancer, from January 2011 to June 2015. We reviewed variables related to the dates of the abnormal test result, first mastology appointment, biopsy, surgery, and the start of chemotherapy ­ when indicated. Time intervals were compared using the Friedman and Kruskal-Wallis tests with the software SPSS® 23.0. Results: We analyzed 65 patients. The median time between the abnormal test result and first mastology appointment was 35 days; between first mastology appointment and biopsy, 31 days; between biopsy and surgery, 85 days; and between surgery and chemotherapy, 137 days. The last two intervals showed significant differences (p<0.001). Discussion: Breast cancer patients had a significant delay until surgery and the start of chemotherapy. Early integration of the multidisciplinary team involved in this process and internal audits are necessary to optimize time intervals.

Introdução: O câncer de mama apresenta bom prognóstico quando tratado precocemente, entretanto, a mortalidade no Brasil continua elevada. O tempo entre suspeita radiológica e diagnóstico e tratamento tem impacto na sobrevida. Métodos: Foi realizado um estudo transversal e retrospectivo que avaliou pacientes atendidas em centro de referência com imagem mamária alterada e posterior confirmação de câncer de mama de janeiro de 2011 a junho e 2015. Foram revisadas variáveis relacionadas às datas do exame alterado, da primeira consulta, da biópsia, da cirurgia e do início da quimioterapia, quando indicada. Os intervalos de tempo foram comparados pelos testes Friedman e Kruskal-Wallis, pelo programa SPSS® 23.0. Resultados: Foram analisadas 65 pacientes. A mediana de tempo entre exame alterado e primeira consulta foi 35 dias, entre consulta na mastologia e biópsia foi 31 dias, entre biópsia e cirurgia foi 85 dias e entre cirurgia e quimioterapia foi 137 dias. Foram observadas diferenças significativas nos dois últimos intervalos (p<0,001). Discussão: As pacientes com câncer de mama apresentaram atraso significativo até a cirurgia e até o início da quimioterapia. Há necessidade da integração precoce da equipe multidisciplinar implicada nesse processo e auditorias internas a fim de otimizar os intervalos de tempo

ANDROGEN RECEPTOR EXPRESSION IN TRIPLE NEGATIVE BREAST CANCER AND ITS RELATIONSHIP TO PROGNOSTIC FACTORS / Expressão de receptor de androgênio em câncer de mama triplo negativo e sua relação com fatores prognósticos

Objective: Triple negative breast cancer (TNBC) is a subset of tumors with an aggressive intrinsic biology, resulting in poor prognosis. Androgen receptor (AR) is currently one of the most studied biomarkers in TNBC, playing a role in the genesis and development of breast cancer. Methods: In this cross-sectional study, we retrospectively reviewed the medical records of all patients with TNBC who received care from 2012 to 2014 at a single health center in southern Brazil. Histological material from breast tumors was analyzed by immunohistochemistry for AR expression and related to age, histological grade, tumor-infiltrating lymphocytes (TILs), and Ki-67. Results: Of 34 TNBC cases identified, 23 (67.6%) were AR negative and 11 (32.4%) were AR positive. The average age of the patients was 51.9 years (range: 30­82 years). Among positive cases, AR was weakly expressed in 6 and strongly expressed in 5 cases. Most patients (n=28; 82.0%) had poorly differentiated tumors. Mean Ki-67 expression was 65.0% in AR-negative and 43.6% in AR-positive cases (p<0.05). There was a significant association between age and AR expression (p<0.005), which was associated with mean age 70.8 years in the strongly AR-positive group and 42.3 years in the weakly AR-positive group. The mean percentage of TILs was 38.6% in AR-positive and 39.1% in AR-negative cases (p=0.391). Conclusion: There was no significant association between AR expression and histological grade or TILs. AR positivity in TNBC was associated with older age and tumors with lower Ki-67 expression, indicating two subgroups with distinct phenotypes in patients with TNBC.

Objetivo: O câncer de mama negativo triplo (triple negative breast cancer ­ TNBC) é um subtipo de tumores com biologia intrínseca agressiva, resultando em pior prognóstico. O receptor de andrógeno (androgen receptor ­ AR) é atualmente um dos biomarcadores mais estudados em TNBC, desempenhando papel na gênese e no desenvolvimento do câncer de mama. Métodos: Neste estudo transversal, revisamos retrospectivamente os registros médicos de todos os pacientes com TNBC que receberam atendimento de 2012 a 2014 em um único centro no sul do Brasil. O material histológico dos tumores de mama foi analisado por imuno-histoquímica para a expressão de AR e relacionado a idade, grau histológico, linfócitos infiltrantes de tumores (TILs) e Ki-67. Resultados: Dos 34 casos identificados de TNBC, 23 (67,6%) eram AR negativos e 11 (32,4%), AR positivos. A idade média foi de 51,9 anos (30­82 anos). Entre os casos positivos, AR foi fracamente expresso em 6 e fortemente expresso em 5 casos. A maioria dos pacientes (n=28, 82,0%) apresentou tumores pouco diferenciados. A expressão média de Ki-67 foi de 65,0% em AR-negativo e 43,6% em AR-positivo (p<0,05). Houve associação significativa entre a idade e a expressão de AR (p<0,005), associada à idade média de 70,8 anos no grupo com AR fortemente positivo e de 42,3 anos no grupo com AR fracamente positivo. A porcentagem média de TILs foi de 38,6% em AR-positivo e de 39,1% em AR-negativo (p=0,391). Não houve associação significativa entre expressão AR e grau histológico ou TILs. Conclusão: A positividade de AR em TNBC foi associada com idade mais avançada e tumores com menor expressão de Ki-67, indicando dois subgrupos com fenótipos distintos em pacientes com TNBC.

Locoregional recurrence in patients with HER2 positive breast cancer.

Literature shows that HER2/neu positive breast cancer cells are more sensitive to radiation-induced apoptosis by targeting the epidermal growth factor receptor family tyrosine kinase. We selected 466 patients with pT1-2 HER2/neu positive tumors who received adjuvant trastuzumab for primary invasive breast cancer. Patients were divided into three groups [Quadrantectomy followed by conventional radiotherapy vs Quadrantectomy followed by Intra-operative radiotherapy with electrons vs Mastectomy without radiotherapy]. After a median follow-up of 52 months, the 5-year cumulative incidence of locoregional recurrence (LRR) was 1.9%, 11.5% and 5.0% respectively (p < 0.01). At the multivariate analysis, extensive perivascular invasion, Luminal B HER2/Progesterone Receptor (PgR) negative status and Quadrantectomy followed by Intra-operative radiotherapy with electrons have significantly increased the risk of LRR. Our results suggest that HER2/neu positive breast cancer might have better outcomes when treated simultaneously with external radiotherapy and trastuzumab. Moreover, we underline the importance of PgR and further new stratification of risk among luminal subtypes.

Adjuvant trastuzumab in elderly with HER-2 positive breast cancer: a systematic review of randomized controlled trials.

Trastuzumab, in combination with chemotherapy, is the gold standard in the adjuvant treatment of patients with HER2 positive breast cancer. Limited data are available on the role of adjuvant trastuzumab in the elderly population. We performed a systematic review of prospective randomized trials with available data on the use of adjuvant trastuzumab in patients older than 60years, focusing on both the efficacy and the cardiac safety. Data extrapolated from two prospective trials were included for efficacy and cardiac safety. A significant 47% relative risk reduction was observed in elderly patients receiving trastuzumab compared to chemotherapy alone (pooled Hazard Ratio: 0.53; 95% CI, 0.36-0.77). The pooled proportion of cardiac events in elderly patients treated with trastuzumab was 5% (95% CI, 4-7%). The use of trastuzumab should be considered as a standard of care in the adjuvant therapy of elderly patients with HER-2 positive breast cancer. Acute and chronic medical conditions, nutritional status and level of daily activities should be considered. Uncertainty about cardiac safety in the elderly is a major concern.

Risk of locoregional recurrence in patients with false-negative frozen section or close margins of retroareolar specimen in nipple-sparing mastectomy.

BACKGROUND: Our purpose was to evaluate the locoregional recurrence (LRR) of patients with false-negative, frozen-section or close margins of retroareolar specimen in nipple-sparing mastectomy (NSM) procedure. METHODS: From 2002-2008, we recruited patients who had atypia or presence of cancer cells in definitive histology of retroareolar tissue despite of absence of tumor cell in intraoperative retroareolar frozen section. We also included the close margin cases defined as the presence of tumor cells at the first frozen section, but after deeper core out of retroareolar tissue were revealed free of malignancy. The incidence of LRR and NAC recurrence were reported, and the factors associated were analyzed. RESULTS: Of 948 NSM procedures, there were 88 false-negative, frozen-sections and 10 close margin cases. The 5-year cumulative incidence of LRR and NAC recurrence was 11.2 % (10/98 patients) and 2.4 % (2/98 patients), respectively. Analyzing the definitive results of retroareolar tissue, the 5-year cumulative incidence of LRR was 42.9 % (n = 4) for atypia, 10 % (n = 2) for lobular carcinoma in situ (LCIS), 10 % (n = 1) for close margins, 8.7 % (n = 3) for ductal carcinoma in situ (DCIS), and 0 % for invasive carcinoma. In situ carcinoma as a primary tumor was a significant predictor of NAC recurrence (P < 0.01). CONCLUSIONS: Despite a high reliability of frozen section, there is still a minority of false-negative results. Nevertheless, the LRR is considerably low. This fact suggests the possibility of preservation of the NAC after discussion with the patient.

Targeting the subtypes of breast cancer: rethinking investigational drugs.

INTRODUCTION: The choice of adjuvant treatments for women with breast cancer is based on several features that take into account the heterogeneity of the disease. Questions raised during the decision process include the following: i) What leads to the use of endocrine therapy? ii) What leads to the use of anti-HER2 therapy? iii) What justifies the use of chemotherapy? AREAS COVERED: Choices of adjuvant treatment are based on parameters defined by molecular characterization of breast cancer subtypes or by approximations to this classification using traditional clinical-pathological features. Clinicians should consider cases within the various distinct subpopulation in order to properly select the most 'personalized' adjuvant therapeutic approach. Sensitivity to chemotherapy and/or targeted agents in subtypes of breast cancers are predictable based on gene pathway alterations and associated gene products. This review covers several clinical data on several investigational agents for early-stage breast cancer molecular subtypes. We selected from literature data prospective Phase I, II and III clinical trials of chemotherapy (weekly or daily schedules), including indicators of activity and toxicity and data on survival/mortality. EXPERT OPINION: The future of many investigational therapeutics in breast cancer is linked to our ability to identify the most druggable target in each subtype.

Biopsy of liver metastasis for women with breast cancer: impact on survival.

BACKGROUND: Biopsy of metastatic site of disease can influence treatment decisions, but its impact on survival remains uncertain. PATIENTS AND METHODS: One-hundred patients with first metachronous liver metastases (LM) from breast cancer (BC) who underwent liver biopsy between 1999 and 2009 were identified. One-hundred matched control patients with LM from BC and no biopsy were selected. RESULTS: Liver biopsy had no statistically significant impact on survival when comparing biopsied patients to controls [HR 0.82 (95% CI 0.58-1.16)]. Patients with early metastasis (within 3 years) undergoing liver biopsy had a better survival [HR 0.60 (95% CI 0.38-0.97)] compared to those who did not. Liver biopsy had no statistically significant impact on survival in patients with late LM (after 3 years) [HR 1.09 (95% CI 0.69-1.74)]. We observed that 18 out of 100 biopsied patients (18.0%) had a conversion of predictive factors which allowed adjusting for therapy, specifically new expression of ER (n=5), overexpression of HER2 (n=12) or both (n=1). Fourteen out of 18 (77.8%) received anti-HER2 treatment for the first time at the time of metastasis and 3 others (16.7%) received hormone therapy. Those 18 patients showed a better survival compared to the other 82 biopsied patients [HR 0.55 (95% CI 0.28-1.10)] and compared to the 13 biopsied patients with disappearance of features which predicted responsiveness to a given treatment [HR 0.19 (95% CI 0.06-0.62)]. CONCLUSIONS: Liver biopsy can impact survival of patients with early metastases from BC. Discordance between primary and distant lesions can offer the patients new treatment options.
