The circulating 70 kDa heat shock protein (HSPA1A) level is a potential biomarker for breast carcinoma and its progression.

The early diagnosis of breast cancer can improve treatment and prognosis. We sought to evaluate whether the serum concentration of the 70 kDa heat shock protein (HSPA1A) was elevated in Brazilian women with breast cancer, and if levels correlated with tumor characteristics. This was a cross-sectional, analytical, case-control exploratory study performed at The University of São Paulo School of Medicine. From September 2017 to December 2018, 68 women with breast cancer and 59 controls were recruited. The HSPA1A concentration in serum samples was determined by ELISA by individuals blinded to the clinical data. The mean ages in the study and control groups were 54.9 and 52.0 years, respectively. The median serum levels of HSPA1A were elevated in women with breast cancer (1037 pg/ml) compared with controls (300 pg/ml) (p < 0.001). Elevated HSPA1A levels were associated with advanced histological tumor grade (p < 0.001) and with the cell proliferation index (KI67) (p = 0.0418). The HSPA1A concentration was similar in women with different histological subtypes, nuclear grade, hormone receptor expression, HER2 status and the presence or absence of angiolymphatic invasion. Elevated serum HSPA1A in Brazilian women with advanced histological grade and proliferation index breast cancer supports the potential value of additional investigation on larger and more varied populations to verify the value of HSPA1A detection as a component of breast cancer diagnosis and progression.

Teleoncology Orientation of Low-Income Breast Cancer Patients during the COVID-19 Pandemic: Feasibility and Patient Satisfaction.

OBJECTIVE: The present study aims to assess the feasibility and patient satisfaction of teleoncology orientation in a vulnerable population of breast cancer patients assessed in a government health system during the coronavirus pandemic in 2020. METHODS: Eligible patients received an invitation to receive remote care to minimize exposure to an environment in which the risk of respiratory infection was present. The means of communication was telephone through an application that allows free conversation with no charge. An anonymous-response questionnaire based on a Likert-type scale was sent through a cell phone application or e-mail directly to each patient or close relative of the patient immediately after teleconsultation. Responses to the questions, which addressed utility, facility, interface quality, interaction quality, reliability, satisfaction, and interest in future evaluation, were compiled and analyzed. RESULTS: A total of 176 eligible patients scheduled for consultation were evaluated and 98 were included. Seventy (71.4%) successfully undertook the teleorientation. The questionnaire was submitted by 43 (61.4%) patients. The overall teleoncology orientation was classified as very positive by 41 (95.3%) patients. Specifically, regarding the questionnaire items, 43 (100%) patients scored 4 or 5 (agreed that the teleconsultation was beneficial) concerning the facility, followed by 42 (97.2%) for the interface quality, 41 (95.3%) for both utility and interaction quality, 40 (93%) for satisfaction and interest in future evaluation, and, finally, 39 (90.6%) for reliability. CONCLUSION: Teleoncology orientation of low-income breast cancer patients is most feasible and leads to high patient satisfaction.

OBJETIVO: O presente estudo teve como objetivo avaliar a viabilidade e satisfação em relação à orientação teleoncológica realizada em população vulnerável de pacientes com câncer de mama e provenientes do sistema público de saúde durante a pandemia do coronavírus em 2020. MéTODOS: Pacientes elegíveis foram agendados para atendimento remoto visando minimizar exposição a ambientes com risco de infecção respiratória. O meio de comunicação foi o telefone, pois permite conversa sem custos. Um questionário anônimo com base na escala Likert foi enviado através de aplicativo de telefone celular ou e-mail para paciente ou familiares, logo após a teleconsulta. As respostas, que abordavam utilidade, facilidade, qualidade da interface, qualidade da interação, confiabilidade, satisfação e interesse em avaliações futuras, foram compiladas e analisadas. RESULTADOS: Um total de 176 pacientes elegíveis para teleconsulta foram avaliados e 98 foram incluídos. Setenta (71,4%) realizaram a teleorientação com sucesso. O questionário foi respondido por 43 (61,4%) pacientes. De maneira geral, a teleorientação foi classificada como muito positiva por 41 (95,3%) pacientes. Em relação aos itens avaliados, 43 (100%) pacientes pontuaram 4 ou 5 (concordaram que a teleconsulta era benéfica) em relação à facilidade do serviço, seguido por 42 (97,2%) para a qualidade da interface, 41 (95,3%) tanto para a utilidade quanto para a qualidade da interação, 40 (93%) para satisfação e interesse em avaliação futura e 39 (90,6%) para confiabilidade em relação ao método. CONCLUSãO: A orientação teleoncológica em pacientes de baixa renda e com câncer de mama mostrou ser viável e com altas taxas de satisfação.
