Temporal Recurrence of Cutaneous Melanoma: Analysis of a Case Series.

Introduction: The recurrence of cutaneous melanoma is one of the main reasons for surveillance after primary tumor treatment, and there is still little data on melanoma recurrence related to the Brazilian population. Objective: We sought to evaluate the profile of patients with cutaneous melanoma recurrence within five years of (early) and five years after (late) initial diagnosis. Methods: Patients diagnosed between 2006 and 2014 in a private reference service in Belo Horizonte, Brazil, were included. Demographic, clinical, histopathological, and disease evolution variables were collected and analyzed using the R version 4.0.0 program. A p-value less than 0.05 was considered significant. Results: The sample was composed of 331 patients with melanoma, and the 43 patients with recurrence presented with higher mean age (p=0.049), male predominance (p=0.030), a lower proportion of Breslow thickness under 0.8mm (p<0.001), and a more significant presence of mitosis (p=0.007). The 29 patients (8.8%) with early recurrence presented with tumors with ulceration (p<0.018). Late recurrence occurred in 14 patients (4.2%). Five patients relapsed after 10 years; most of them had tumors up to 1mm thick, without ulceration, regression, or satellitosis, but with the presence of mitosis. Conclusion: The possibility of cutaneous melanoma recurrence after five, and even 10, years, although rare, might indicate the need for longer medical follow-up. Multicenter studies may better characterize Brazilian patient profiles of those with early and late recurrence of melanoma.

Does it fit in your pocket? economic burden of PD-1 inhibitors' toxicity in the supplementary health system: evidence from Brazil.

BACKGROUND: A full understanding of the economic burden associated with treatment-related adverse events (AEs) can aid estimates of the incremental costs associated with incorporating new technologies and support cost-effective economic modeling in Brazil. In this context, the main objective of this work was to evaluate in a real-life database: (i) the direct medical cost of monitoring the occurrence of AEs (CMO); (ii) the direct medical cost of managing an identified AE (CMN); and (iii) the total direct medical cost of monitoring and managing AEs (TMC), in quarterly periods from 0 to 24 months of the monitoring of cancer patients who used a PD-1 inhibitor from the perspective of the supplementary health system in Brazil. METHODS: This study was conducted from the supplementary health system (SSS) perspective and followed the methodological guidelines related to cost-of-illness studies. A bottom-up (person-based) approach was used to assess the use of health resources to monitor and manage AEs during the use of PD-1 inhibitors, which made it possible to capture differences in the mean frequency of the use of health services with stratification results for different subgroups. As the Brazilian SSS is complex, asymmetric, and fragmented, this study used information from different sources. The methodology was divided into three parts: (i) Data Source: clinical management of AEs; (ii) Microcosting: management of the economic burden of AEs; (iii) Statistical analysis: stratification of results for different subgroups. RESULTS: Analysis of the economic burden of toxicity showed higher CMO costs than CMN in all the periods analyzed. In general, for every BRL 100 on average invested in the TMC of AEs, BRL 95 are used to monitor the occurrence of the AE and only BRL 5 to manage an identified AE. This work also showed that the sociodemographic characteristics of patients, the journey of oncological treatment, and the toxicity profile affect the economic burden related to AE. CONCLUSION: This study provided real-world evidence of the economic burden of AEs associated with the use of PD-1 inhibitors in Brazil. This work also made methodological contributions by evaluating the economic burden of AE of PD-1 inhibitors considering the kinetics of toxicity occurrence and categorizing the costs in terms of CMO, CMN and TMC.

Follow up of utility and value of totally implantable chemotherapy catheter in 233 brazilian patients receiving chemotherapy to treat cancer.

OBJECTIVES: the present study aims to evaluate cancer patients related to the catheter flow and the general satisfaction of these patients. METHODS: we studied 233 individuals diagnosed with cancer who underwent chemotherapy treatment through venous access through portocath between January 2015 and December 2019. RESULTS: 97% of the patients consulted had palliative chemotherapy, and 99.1% of patients reported satisfaction with the implantation process and treatment method. Regarding catheter flow according to venous return and drip during drug infusion, 98.7% of individuals presented good flow. CONCLUSIONS: the results show that catheter flow was satisfactory in all implant sites observed and emphasize the advantages of using a totally implanted catheter. This benefice happens due to the reduction of emotional factors that cause stress in cancer patients receiving chemotherapy, as well as the reduction of trauma and discomfort experienced by patients during the infusion of peripheral chemotherapy.

Assessment of Medical Students' Knowledge of Imaging Methods for Bone Sarcomas.

Cancer is a leading cause of death in Brazil and worldwide. However, Brazilian medical education fails to include oncology as an essential topic. This creates a gap between the health status of the population and medical education. Bone sarcomas fall into both the group of malignant neoplasms and rare diseases and are thus doubly influenced by misinformation. To assess medical students' knowledge of imaging diagnostic methods for bone sarcomas. A cross-sectional, quantitative study was undertaken by obtaining the responses of medical students to a questionnaire containing radiographic images and questions about the radiological aspects of bone sarcomas. The categorical variables were compared using the chi-square test. The level of significance was 5% for all the tests. SPSS software version 25.0 was used for the analysis. A total of 325 responses were collected, with 72% of the participants having no interest in oncology and 55.6-63.9% not knowing how to diagnose a periosteal reaction on bone radiography. Only 11.1-17.1% of the students correctly interpreted the radiographic image of osteosarcoma. Medical students fail to correctly interpret images of bone sarcomas. It is important to promote oncology undergraduate education in general and to include the approach to bone sarcomas in this context.

Impact of second histopathological review of melanocytic skin lesions at a melanoma reference center in Brazil.

BACKGROUND: After the biopsy of a suspicious melanocytic lesion, patients depend on the pathologist's precision of specimen evaluation. METHODS: We assessed the agreement between histopathological reports made by general pathologists and reviewed by a dermatopathologist to evaluate the impact on the patient's management. RESULTS: In 79 cases analyzed, underdiagnosis was observed in 21.6% and overdiagnosis in 17.7%, resulting in changes in the patients' conduct. The assessment of the Clark level, ulceration and histological type showed mild agreement (P<0.001); the Breslow thickness, surgical margin, and staging showed moderate agreement (P<0.001). CONCLUSIONS: A dermatopathologist's review should be incorporated into the routine of reference services for pigmented lesions.

Pain Treatment and Cancer Patients: Are we Heeding Quality of Life?

The use of opioid analgesics remains the primary therapy for pain control in cancer patients. However, ample evidence persists showing that treatment is still inadequate. This cross-sectional study was carried out during one year in a Brazilian Cancer Hospital to evaluate the impact of opioid use on analgesia and patients' quality of life. The Pain Management Index (PMI), EORTC QLQ.C30 (Quality of Life of Cancer Patients), Karnofsky Performance Status (KPS), Douleur Neuropathique 4 (DN4), and Brief Pain Inventory-Short Form (BPI-SF) were used. A hundred patients with advanced solid tumors and using opioids were included, with 82% of them reporting daily pain with 58% having intense pain. Morphine with a mean dose of 49 Morphine Milligram Equivalent were used by 57% of them, and PMI was negative in 34% of the sample. Neuropathic pain was found in 72% of patients. The pain was related to all BPI variables. Despite the substantial negative impact of pain on QOL, no association was found between the clinical factors assessed and QOL itself. This gap can be related to the persistence of high levels of sub-treatment, depression, and neuropathic pain associated with the use of low doses of opiates and adjuvant medications in the sample.

Follow up of utility and value of totally implantable chemotherapy catheter in 233 brazilian patients receiving chemotherapy to treat cancer / Acompanhamento da utilidade e valor do cateter de quimioterapia totalmente implantável em 233 pacientes brasileiros que receberam quimioterapia para tratar o câncer

ABSTRACT Objectives: the present study aims to evaluate cancer patients related to the catheter flow and the general satisfaction of these patients. Methods: we studied 233 individuals diagnosed with cancer who underwent chemotherapy treatment through venous access through portocath between January 2015 and December 2019. Results: 97% of the patients consulted had palliative chemotherapy, and 99.1% of patients reported satisfaction with the implantation process and treatment method. Regarding catheter flow according to venous return and drip during drug infusion, 98.7% of individuals presented good flow. Conclusions: the results show that catheter flow was satisfactory in all implant sites observed and emphasize the advantages of using a totally implanted catheter. This benefice happens due to the reduction of emotional factors that cause stress in cancer patients receiving chemotherapy, as well as the reduction of trauma and discomfort experienced by patients during the infusion of peripheral chemotherapy.

RESUMO Objetivos: avaliar pacientes com câncer em relação ao fluxo do cateter e a satisfação geral desses pacientes. Métodos: estudo retrospectivo avaliando prontuários de 233 indivíduos com diagnóstico de câncer que realizaram tratamento quimioterápico por acesso venoso por portocath entre janeiro de 2015 e dezembro de 2019. Resultados: 97% dos pacientes realizaram quimioterapia paliativa, e 99,1% dos pacientes relataram satisfação com o processo de implantação e método de tratamento. Em relação ao fluxo do cateter de acordo com o retorno venoso e gotejamento durante a infusão da droga, 98,7% dos indivíduos apresentaram bom fluxo. Conclusões: os resultados mostram que o fluxo do cateter foi satisfatório em todos os locais de implante observados e enfatizam as vantagens do uso de um cateter totalmente implantado. Esse benefício acontece devido à redução de fatores emocionais que causam estresse em pacientes oncológicos em tratamento quimioterápico, bem como a redução de traumas e desconfortos vivenciados pelos pacientes durante a infusão de quimioterápicos periféricos.

Complications of Extended Pelvic Lymph Node Dissection in Patients Undergoing Minimally Invasive Radical Prostatectomy: Analysis and Risk Factors.

Background: The knowledge of risk factors and complications related to extended pelvic lymph node dissection (ePLND) during radical prostatectomy can help selecting patients who will benefit the most with lymph node dissection concomitant to radical prostatectomy. Materials and Methods: Retrospective cohort evaluating 135 patients with PC, with a high risk for lymph node metastasis, submitted to ePLND by a single surgeon between 2013 and 2019, performed either by the laparoscopic or laparoscopic robot-assisted approach. Data related to complications were properly recorded using the Martin's criteria and were classified by the Satava and Clavien-Dindo-Strasberg methods. Logistic regression was used to determine predictors of complications related to ePLND. Results: The mean number of lymph nodes removed was 10.2 ± 4.9, and in 28.2%, they were positive for metastasis. There were five intraoperative complications (4%), all in patients operated by laparoscopic approach. There were nine severe postoperative complications (7.3%), four of which occurred after postoperative day 30. Three patients (2.4%) had thromboembolic complications and five patients (4.0%) had lymphocele that required treatment. There was a correlation between the American Society of Anesthesiologists (ASA) physical status classification and postoperative complications (p=0.06), but it was not possible to identify statistically significant predictors. Conclusion: ePLND during radical prostatectomy has a low rate of intraoperative complications and may change prostate cancer staging. Postoperative complications, especially venous thromboembolism and lymphocele, need to be monitored even in the late postoperative period.

Impact of proper surgical treatment on the survival of patients with epithelial ovary cancer.

OBJECTIVE: to evaluate the quality of surgical treatment of ovarian cancer patients and assess the impact of adequate surgical oncological treatment on disease-free survival and overall survival of patients with advanced epithelial ovarian cancer. METHODS: this is an observational, retrospective study with quantitative analysis, with the collection of data in medical records of a temporal convenience sample of patients diagnosed with ovarian cancer admitted to a High Complexity Oncology Unit, in Belo Horizonte, from the period of 2014 to 2020. RESULTS: a total of 91 patients diagnosed with ovarian cancer were evaluated, with the epithelial histopathological type being the most frequent (85%). Of this total, 68 patients (74.7%) had advanced-stage ovarian cancer. Appropriate surgical treatment was performed in 30.9% of patients with advanced epithelial ovarian cancer and the type of performed surgery was statistically significant for overall survival. This low proportion of appropriate surgical oncological treatment was not related to surgical specially or surgeon competence, but mainly to advanced disease related to patient flow at UNACON. It was not possible to confirm if the advanced-stage disease was related to tumor biology or losing time from diagnosis to oncological surgery. CONCLUSION: overall survival of advanced-stage epithelial ovarian cancer patients is directly influenced by appropriate surgical treatment, however, in this study, the percentage of advanced ovarian cancer receiving adequate surgical treatment was much lower than the rates reported in the literature. To improve these outcomes, we believe that surgeons should keep following patients during neoadjuvant chemotherapy to point to a better time for surgery, and clinical oncologists should better consider adequate oncological surgery as one of the pillars of ovarian cancer treatment and get more involved in facilitating surgeries.

Cancer patients admitted in the emergency department: A single-centre observational study.

OBJECTIVE: This study aims to analyse patients' clinical profiles seen at an emergency unit of a public oncology reference hospital in Belo Horizonte, Brazil. METHODS: This is a cross-sectional, observational, retrospective study, with data collection through patients' medical records seen between 2016 and 2018. The identification of patients was carried out through research on hospital admission authorization guides. RESULTS: A total of 2932 medical records were evaluated, of which only 21.5% were cancer patients. A cancer diagnosis was made for 21.5% of patients during hospitalisation. In this group, pain and weight loss are frequent symptoms, and haematological diseases (15.2%) were the most frequent tumour type. Patients with a previous cancer diagnosis presented the most prevalent tumour breast (18.3%) and altered consciousness level as a leading symptom. Analgesics were the most prescribed drugs in both groups. CONCLUSION: This study showed two distinct groups of cancer patients: with or without a previous cancer diagnosis. However, these two groups are comparable in almost all the variables analysed. Therefore, we believe that the factors that could guide the care in an emergency are related to education on cancer symptoms for the population to contribute to an early diagnosis and cancer training for emergency department (ED) professionals' to better monitor advanced-stage patients for symptom management.

Factors Related to Delayed Diagnosis of Cutaneous Melanoma in the Brazilian Public Health System.

In Brazil, 75% of the population uses the Sistema Único de Saúde (SUS), public health system, where the general practitioner (GP) is responsible for melanoma diagnosis. Identify the factors related to the delay in diagnosing melanoma patients assisted by SUS. A prospective observational study based on a questionnaire and medical records review assessed the sociodemographic features, melanoma signs and symptoms, previous knowledge of the disease, and factors related to delays in seeking medical care. One hundred sixty-six patients were included. Healthcare professionals suspected a lesion in only 23.5% of cases. The average time between lesion suspicion by patient/relative and first medical appointment with GP was over 6 months (31%). The time between the first GP exam and biopsy conducted by a specialist ranged from less than 1 month (34.9%) to more than 1 year (18.7%). Half of the patients (49.4%) experienced delays in histopathological diagnosis due to SUS bureaucracy/slowness. Most (80%) patients did not know what melanoma was before diagnosis. Delay in melanoma diagnosis was related to a lack of knowledge about the disease's signs and symptoms for both the study population and the primary physicians, indicating that both players must receive proper education about melanoma. Also, the infrastructure and work processed at SUS impeded the patient flow, contributing to the diagnosis of the lesions at more advanced stages.

Toxicity profile of treatment with PD-1 inhibitors for lung cancer, melanoma and renal cell carcinoma: A real-world Brazilian study.

INTRODUCTION: Immunotherapy revolutionized cancer care in the last decade and, notably among its tools, the programmed cell death protein-1 (PD-1) inhibitors. These drugs are related to increased life expectancy rates. However, they can cause several adverse events that have not been fully characterized, thus challenging clinical practice. OBJECTIVE: To evaluate the toxicity profile, determining its frequency, causality, and severity associated with treatment with PD-1 inhibitors in patients treated at an oncology service in the private health sector in Belo Horizonte. METHODS: Observational, retrospective, and cross-sectional study, based on the review of electronic medical records. The eligibility criteria included patients over 18 years old with a diagnosis of any cancer and staging, receiving a PD-1 inhibitor from January 2017 to January 2020. RESULTS: The sample consisted of 134 patients with lung cancer (46,3%), melanoma (34,3%), and kidney cancer (19,4%). The most common adverse event (AE) related to treatment were fatigue (51.5%), anorexia (23.1%), hypothyroidism (15.7%), and skin rash (14.9%), being grades 1 and 2 more prevalent. Between 3 and 12 months, there were more cutaneous, nutritional, and metabolic toxicities, and fatigue was present throughout the entire treatment period. Gastrointestinal and pulmonary toxicities were more frequent up to the 9th month. CONCLUSION: Based on real-world evidence, it was possible to reveal important findings to support the safe practice of PD-1 inhibitors treatment. Fatigue was the most prevalent AE among patients. In addition, the kinetics of AE allowed the identification of major occurrences according to the period o treatment, allowing more precise monitoring and surveillance.

Is a law enough to provide a better prognosis for Brazilian melanoma patients or education is still a gap?

According to Brazilian Law 12.732/12 ("60-day law"), cancer patients have 60 days after diagnosis for beginning treatment at the Unified Health System (SUS). The study aimed to evaluate the achievement and effectiveness of the '60-day law' for melanoma patients in a SUS cancer reference unit. A retrospective study analysed 58 medical charts from patients with the initial diagnosis performed before and after the "60-day law". The Law does not change the time interval between diagnosis and the beginning of treatment, and after the Law, patients presented a worse overall survival (p < 0.001). In conclusion, the '60-day law' was not effective.

Sentinel Lymph Node Biopsy after Previous Radical Lymphadenectomy of the Same Lymph Node Basin.

Purpose: This study aimed to determine the feasibility of preoperative lymphoscintigraphy and intraoperative radio-guided sentinel lymph node biopsy (SLNB) in patients previously submitted to complete lymphadenectomy (CL) in the same region. There is no current proposal to stage patients diagnosed with a new melanoma after SLNB if the regional lymph node (LN) was removed, preventing this specific population from adjuvant treatments due to understaging.Methods: We assessed six cases of patients with a previous cancer diagnosis (melanoma, breast, or thyroid cancer) who had undergone CL and later developed a new cutaneous melanoma in the same extremity submitted to CL. They underwent preoperative lymphoscintigraphy to locate the sentinel lymph node (SLN), followed by a radio-guided SLNB with the assistance of patent blue dye. A pathologist then evaluated the excised SLN.Results: We had 100% feasibility, all six patients had their SLN located, and three (50%) patients tested positive for metastasis in the excised LNs.Conclusions: All these patients met the criteria to undergo SLNB, but no previous reports demonstrated and corroborated the performance of this procedure in this situation. SLNB with expected drainage for regions previously submitted to a radical lymphadenectomy is a safe and effective procedure. A lymphoscintigraphy allows locating the SLN that is likely to be resected in surgery. In this scenario, we had a 50% positivity, providing how relevant and essential this information is for the prognosis and practical therapeutical approaches for this rare but relevant melanoma population.

ARE THERE DIFFERENCES IN LAPAROSCOPIC GASTRECTOMY MORBIDITY AND MORTALITY BETWEEN YOUNG AND OLDER?

BACKGROUND: Due to the longer life expectancy and consequently an increase in the elderly population, a higher incidence of gastric cancer is expected in this population in the coming decades. AIM: To compare the results of laparoscopic GC surgical treatment between individuals aged<65 years (group I) and ≥ 65 years (group II), according to clinical, surgical, and histopathological characteristics. METHODS: A observational retrospective study was performed by analyzing medical charts of patients with gastric cancer undergoing total or subtotal laparoscopic gastrectomy for curative purposes by a single oncologic surgery team. RESULTS: Thirty-six patients were included in each group. Regarding the ASA classification, 31% of the patients in group I was ASA 1, compared to 3.1% in group II. The mean number of concomitant medications in group II was statistically superior to group I (5±4.21 x 1.42±3.08, p<0.001). Subtotal gastrectomy was the most performed procedure in both groups (69.4% and 63.9% in groups I and II, respectively) due to the high prevalence of distal tumors in both groups, 54.4% group I and 52.9% group II. According to Lauren's classification, group I presented a predominance of diffuse tumors (50%) and group II the intestinal type (61.8%). There was no difference between the two groups regarding the number of resected lymph nodes and lymph node metastases and the days of hospitalization and mortality. CONCLUSION: Laparoscopic gastrectomy showed to be a safe procedure, without a statistical difference in morbidity, mortality, and hospitalization time between both groups.

Identification of victims of the collapse of a mine tailing dam in Brumadinho.

The collapse of the B1 Dam of VALE SA mining company in Brumadinho, Minas Gerais, Brazil was the largest humanitarian disaster and occupational accident in the country's history, and it posed challenges regarding the management and identification of multiple victims. We evaluated the impact of the iron ore tailings on the victims' bodies. We examined the scientific identification of the victims and the dynamics of the disaster over the 1st year after it occurred. We also determined the socio-demographic profiles of the victims. In this retrospective, cross-sectional study, we investigated the expert reports of the victims' biological remains from 25 January 2019 to 25 January 2020. We analysed the socio-demographic data, identification methods, identification status, identification time, and necroscopic information. During the study period, 259 of 270 victims were identified, and 603 biological materials were analysed; among them, 86.2% were body parts and 13.8% were whole bodies. Of the total cases registered that year, 476 (78.9%) were submitted during the first 10 weeks after the disaster. Friction ridge analysis accounted for 67.9% of primary identifications and DNA analysis did so for 91.6% of re-identification cases. Body dismemberment was 3.4 times greater among mine workers than among community victims. Adult males accounted for the greatest number of victims (P < 0.001). Polytraumatic injury was the prevalent single cause of death. Necropsy examination revealed the occurrence of asphyxia in 7% of cases. The higher number of fatalities and greater dismemberment among employees than with community residents underlines the occupational dangers in the mining industry and clarifies the dynamics of the disaster. In the initial weeks after the dam collapsed, friction ridge analysis was the most appropriate method for identification. Subsequently, DNA analysis became the most-used technique for identification and re-identification owing to the great volume of body parts and decomposed biological tissue. Autopsy allowed diagnosis of the causes of death to be clarified according to the Brazilian criminal legal system.

Impact of proper surgical treatment on the survival of patients with epithelial ovary cancer / Impacto do tratamento cirúrgico adequado na sobrevida de mulheres com carcinoma epitelial ovariano

RESUMO Objetivo: avaliar a qualidade do tratamento cirúrgico de pacientes com câncer de ovário e o impacto do tratamento oncológico cirúrgico adequado na sobrevida livre de doença e sobrevida global de pacientes com câncer de ovário epitelial avançado. Métodos: Trata-se de um estudo observacional, retrospectivo, de análise quantitativo, com coleta de dados em prontuários de uma amostra de conveniência temporal de pacientes com diagnóstico de câncer de ovário internadas em uma Unidade de Oncologia de Alta Complexidade (UNACON), em Belo Horizonte, no período de 2014 a 2020. Resultados: foram avaliadas 91 pacientes diagnosticadas com câncer de ovário, sendo o tipo histopatológico epitelial o mais frequente (85%). Desse total, 68 pacientes (74,7%) apresentavam câncer de ovário em estágio avançado. O tratamento cirúrgico adequado foi realizado em 30,9% das pacientes com câncer de ovário epitelial avançado e o tipo de cirurgia realizada foi estatisticamente significativo para a sobrevida global. Essa baixa proporção de tratamento cirúrgico oncológico adequado não esteve relacionada à especialidade cirúrgica ou competência do cirurgião, mas principalmente à doença avançada relacionada ao fluxo de pacientes na UNACON. Não foi possível confirmar se a doença em estágio avançado estava relacionada à biologia tumoral ou à perda de tempo do diagnóstico para a cirurgia oncológica. Conclusão: A sobrevida global de pacientes com câncer de ovário epitelial em estágio avançado é diretamente influenciada pelo tratamento cirúrgico adequado. Porém, o percentual de câncer de ovário avançado recebendo tratamento cirúrgico adequado foi muito inferior aos índices relatados na literatura. Para melhorar esses resultados, acreditamos que os cirurgiões devem continuar acompanhando as pacientes durante a quimioterapia neoadjuvante para apontar um melhor momento para a cirurgia, e os oncologistas clínicos devem considerar melhor a cirurgia oncológica adequada como um dos pilares do tratamento do câncer de ovário e se envolver mais na facilitação das cirurgias.
