RESUMO

OBJECTIVES: This study is a meta-analysis of prior publications evaluating the impact of time-to-chemotherapy (TTC) on disease recurrence and survival 3 years after the original surgery. METHODS: We performed a meta-analysis of studies published in PubMed (1950-2016) as of April 2016. Inclusion criteria were as follows: randomized controlled trials and prospective or retrospective cohorts that included patients with ovarian cancer who had undergone surgery with curative intent and use of adjuvant chemotherapy. We compared rates of disease recurrence and death according to the TTC ("early" vs "delayed") using a random-effects model and performed a metaregression to evaluate the impact of covariates on these outcomes. RESULTS: Of 239 abstracts in the original search, 12 were considered eligible. The cutoffs used for TTC were between 20 and 40 days. All studies used a platinum-based chemotherapy, and the rates of patients with suboptimal resection varied from 33% to 70%. A longer TTC was not associated with higher rates of disease recurrence (odds ratio, 0.89; 95% confidence interval, 0.63-1.24) or death at 3 years (odds ratio, 1.06; 95% confidence interval, 0.9-1.24). There was no evidence of significant publication bias (Egger test P = 0.472), but data were heterogeneous (I = 64.3%). Metaregression showed that the percentage of patients with suboptimal surgery and values used as cutoff to define "delayed" chemotherapy combined were a significant source of bias (residual I = 0%). CONCLUSIONS: In our analysis, TTC after surgery for ovarian cancer with curative intent was not associated with higher risk of disease recurrence or death. However, this association was influenced by the rate of optimal debulking and definition of "late" initiation of chemotherapy, so we must be careful when applying these data to patients with complete resection.

RESUMO

INTRODUCTION: Tumor-infiltrating lymphocytes (TIL) is a predictive and prognostic biomarker for breast cancer (BC) HER2-positive and triple negative, but its presence in HER2-low tumors is unknown. We aimed to determine TIL levels in HER2-low tumors and its correlation with other clinicopathologic features. MATERIALS AND METHODS: We retrospectively analyzed all the pathology reports of breast surgeries of a tertiary hospital in Sao Paulo, Brazil, from January 2021 to March 2022. Inclusion criteria were stage I to III invasive BC, and exclusion criteria were nonmalignancies and neoadjuvant therapy. We assumed HER2 categories according to ASCO/CAP guidelines. TILs were defined as absent (0), low (1%-10%), intermediate (11%40%) and high (≥ 41%). Ki-67 levels were categorized as low (up to 19%) and high (≥ 20%). RESULTS: From 272 patients, 198 met the inclusion criteria. Histological grade 3 was found in 10, 19 and 47% of HER2-0, low, and positive tumors (P < .001). HER2-positive tumors had 82.6% of high Ki-67 levels, while HER2-negative and HER2-low showed 25.8% and 31.4% (P = .005). TILs in HER2-0, low, and positive tumors were, respectively, absent in 16.1%, 17.6%, and 8.7%; low in 70.2%, 52.9% and 34.8%; intermediate in 11.3%, 25.5% and 47.8%; and high in 2.4%, 3.9% and 8.7%. There was a statistically significant difference in TILs between HER2-negative versus HER2-positive groups (P < .001), but not between HER2-negative versus HER2-low, or HER2-low versus HER2-positive. CONCLUSION: TILs in HER2-low are marginally higher than HER2-negative, but significantly lower than HER2-positive levels. HER2-low tumors do not seem to significantly differ biologically from HER2-negative tumors.

RESUMO

OBJECTIVE: To evaluate the impact of COVID-19 pandemic on the care delivered to hospitalized cancer patients in end-of-life. METHODS: A retrospective analysis of data of hospitalized patients with advanced solid tumors, who died under exclusive palliative care during first wave (March 2020 to July 2020) compared with the period previous pandemic (January 2018 to February 2020). RESULTS: A total of 190 oncologic patients were included, 161 patients before the pandemic, and 29 in the period from March 2020 to July 2020. The average hospitalization was 497.2 patients per month, before the pandemic, and dropped to an average of 46.5 in the pandemic, whereas the death rate decreased from an average of 6.3 patients per month to 4.8. Considering the benchmarks for quality of care during end-of-life care, preferences on life assistance were discussed prior to hospitalization for 34.4%, before the pandemic, and 13.8% during the pandemic (p=0.0298); 9.3% received chemotherapy 15 days prior to the date of death, before the pandemic, and 20.7%, in the pandemic (p=0.1012). CONCLUSION: Based on the present results, despite the decrease in oncology admissions, the advanced-stage cancer patients continued to seek hospital for end-of-life care. However, we could observe in our benchmarking analyses for palliative quality of care that talks about prognosis occurred less often during the pandemic.

RESUMO

Compliance with legal deadlines for the assessment and incorporation of technologies in Brazil's Unified Health System (SUS) is essential to ensure public access to essential medicines. The scope of this paper was to analyze the compliance with legal deadlines for incorporation and availability of medicines in the SUS, comparing Oncology and the Specialized Component of Pharmaceutical Assistance (SCPA). A comparison was made of the drugs incorporated that were submitted to Conitec in the period from January 1, 2017, to April 30, 2020. A total of 85 drugs were recommended for incorporation by Conitec, of which 15 (17.64%) were for Oncology and 70 (82.36%) were for SCPA. The time between analysis and recommendation by Conitec until the publication of the decision by the Ministry of Health was, on average, 86 days longer for oncological drugs and the availability timeframe of technologies incorporated in the oncology area was, on average, 389 days longer than for SCPA. The major progress achieved with the creation of Conitec in Brazil is acknowledged, but the results of this study point to a pressing need to improve the process of making available technologies incorporated into the SUS, especially in oncology.


O cumprimento dos prazos legais para incorporação e disponibilização de tecnologias no Sistema Único de Saúde (SUS) é fundamental para o acesso da população aos medicamentos considerados essenciais. Objetivou-se analisar o cumprimento destes prazos comparando a Oncologia e o Componente Especializado de Assistência Farmacêutica (CEAF). Comparou-se os processos de incorporação de medicamentos no SUS da Oncologia e do CEAF que foram submetidos à Conitec no período de 01 de janeiro de 2017 a 30 de abril de 2020. No período, 83 processos de incorporação de medicamentos foram recomendados para incorporação pela Conitec, dos quais 13 (15,66%) eram da Oncologia e 70 (84,34%) eram do CEAF. Verifica-se que o tempo de análise e recomendação pela Conitec até a publicação da decisão pelo Ministério da Saúde foi, em média, 15 dias maior para processos que continham medicamentos oncológicos e o tempo para disponibilização das tecnologias incorporadas da área da oncologia foi, em média, 389 dias maior que do CEAF. Reconhece-se o importante avanço obtido com a criação da Conitec no Brasil, porém os resultados deste estudo apontam para a necessidade de aprimoramento do processo de disponibilização de tecnologias incorporadas no SUS, em especial da Oncologia.

RESUMO

Background: Oncotype DX (ODX) is a validated assay for the prediction of risk of recurrence and benefit of chemotherapy (CT) in both node negative (N0) and 1-3 positive nodes (N1), hormone receptor positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) early breast cancer (eBC). Due to limited access to genomic assays in Brazil, treatment decisions remain largely driven by traditional clinicopathologic risk factors. ODX has been reported to be cost-effective in different health system, but limited data are available considering the reality of middle-income countries such as Brazil. We aim to evaluate the cost-effectiveness of ODX across strata of clinical risk groups using data from a dataset of patients from Brazilian institutions. Methods: Clinicopathologic and ODX information were analyzed for patients with T1-T3, N0-N1, HR+/HER2- eBC who had an ODX performed between 2005 and 2020. Projections of CT indication by clinicopathologic criteria were based on binary clinical risk categorization based on the Adjuvant! Algorithm. The ODX score was correlated with the indication of CT according to TAILORx and RxPONDER data. Two decision-tree models were developed. In the first model, low and high clinical risk patients were included while in the second, only high clinical risk patients were included. The cost for ODX and CT was based on the Brazilian private medicine perspective. Results: In all, 645 patients were analyzed; 411 patients (63.7%) had low clinical risk and 234 patients (36.3%) had high clinical risk disease. The ODX indicated low (<11), intermediate (11-25), and high (>25) risk in 119 (18.4%), 415 (64.3%), and 111 (17.2%) patients, respectively. Among 645 patients analyzed in the first model, ODX was effective (5.6% reduction in CT indication) though with an incremental cost of United States Dollar (US$) 2288.87 per patient. Among 234 patients analyzed in the second model (high clinical risk only), ODX led to a 57.7% reduction in CT indication and reduced costs by US$ 4350.66 per patient. Conclusions: Our study suggests that ODX is cost-saving for patients with high clinical risk HR+/HER2- eBC and cost-attractive for the overall population in the Brazilian private medicine perspective. Its incorporation into routine practice should be strongly considered by healthcare providers.

RESUMO

PURPOSE: Complete androgen blockade (CAB) does not prolong overall survival (OS) in patients with castration refractory prostate cancer (CRPC). Although there is variable clinical benefit with second-line hormone manipulation, we do not know which patients might benefit the most. OBJECTIVES: To identify clinical predictors of benefit of complete androgen blockade. MATERIALS AND METHODS: We reviewed the records for 54 patients who received treatment with CAB in the setting of disease progression despite castration. We evaluated progression-free survival (PFS) and OS according to PSA at diagnosis, Gleason scores, age, testosterone level, and duration of prior disease control during castration in first line treatment. RESULTS: Among 54 patients who received CAB, the median PFS was 9 months (CI 4.3-13.7) and OS was 36 months (CI 24-48). We did not find an effect of PSA at diagnosis (p = 0.32), Gleason score (p = 0.91), age (p = 0.69) or disease control during castration (p = 0.87) on PFS or OS. Thirty-four patients subsequently received chemotherapy, with a mean OS of 21 months (CI 16.4-25.5, median not reached). CONCLUSION: Age, Gleason score, PSA at diagnosis and length of disease control with castration did not affect PFS or OS. In the absence of predictors of benefit, CAB should still be considered in CRPC.

RESUMO

Geriatricians and general practitioners often follow patients with metastatic prostate cancer. The epidemiology and basic treatment principles of metastatic prostate cancer are discussed aiming to update the topic for the non-oncologist. Hormone manipulation remains the basis of treatment, usually up to a second line of therapy. Selected cases are treated successfully with intermittent androgen ablation. When new hormone-independent clones arise, chemotherapy should be added to therapy that confers improved survival as well as better quality of life when based on taxanes. In specific situations, additional measures such as bisphosphonates and radiation therapy should be included in the treatment. As a rule, the public health system makes available the necessary medication to ensure treatment for the vast majority of patients in Brazil.

RESUMO

BACKGROUND: To identify potential delays in the management of patients with breast cancer examined at a public hospital, from time of suspicion until diagnosis and beginning of treatment. METHODS: Retrospective study which analyzed data related to time elapsed in different intervals between suspicion, diagnosis and onset of systemic cancer-directed treatments, of consecutive breast cancer patients cared for at the medical oncology clinic of the Mario Covas Hospital during 2006. RESULTS: Sixty-eight women, with a mean age of 56.3 years (standard deviation: 12.2 years), were included. Of all the intervals, the longest delay occurred between the mammographic suspicion of cancer and performance of biopsy (median of 72 days, range: 4 - 1095 days); this was significantly longer (P<0.001) than in the other intervals analyzed. Furthermore, this interval in particular, was significantly longer in patients with advanced stage breast cancer when compared to those at the initial stage (P=0.014). CONCLUSION: Breast cancer patients treated in a public hospital in Brazil suffer delays, especially during the diagnosis of their disease. Minimizing the time between mammography and biopsy of suspicious lesions appears to be the most critical step to correct this situation.

RESUMO

Breast reduction surgery is a common procedure and the rate of incidental findings in the removed specimens varies between 0% and 4.6%. There are no guidelines about pathological evaluation of breast reduction surgery. We reviewed all pathology reports of patients undergoing breast reduction surgery in a single tertiary institution in Brazil from January 2008 to August 2014. Exclusion criteria were a personal history of breast cancer, unclear reason for mastectomy and incomplete data on the pathology report. We considered "relevant findings" flat epithelial atypia, atypical hyperplasia, carcinomas in situ and invasive carcinoma. Of 1672 specimens from breast reduction surgery, 783 met inclusion criteria. Median patient age was 40 (8-77), 91% underwent bilateral mastectomy and 57% of the specimens weighted less than 200 g. In 55% of cases, 4 or more paraffin blocks were sampled. There were 40 (5.1%) relevant findings and the most common was atypical lobular hyperplasia (16-2%). There were 3 invasive carcinomas (0.38%). In multivariate analysis, the only variables associated with a higher odds of relevant pathological findings were patient age ≥ 40 (OR 4.73 CI95% 1.98-11.3 p < 0.001) and sampling of ≥4 paraffin blocks from each specimen (OR 6.69 95% CI 2.25-19.9 p < 0.001). The incidence of pre-malignant and malignant lesions in specimens from breast reduction surgery is around 5%, but this risk is significantly higher for patients older than 40 years-old. Sampling at least 4 paraffin blocks from each specimen significantly increases detection rates.

RESUMO

BACKGROUND: To evaluate the prognostic value of the ratio between positive and total dissected lymph nodes in patients with colon cancer who underwent primary tumor surgical resection. METHODS: Retrospective chart review of consecutive patients with colon cancer treated at hospitals affiliated to the ABC Foundation School of Medicine, Santo André. Demographic data were collected as well as information on colon cancer, treatment and clinical outcomes. RESULTS: One hundred and six patients were included. Mean age was 62.82+/-11.6 years and most were men (53.8%). Median number of lymph nodes dissected per patient was 11.5 (3-45 lymph nodes) and 58.5% had more than 10 dissected lymph nodes. The median follow-up was 25.05+/-15.21 months (2-64 months). In univariate analysis for overall survival, lymph node ratio (p=0.044), tumor stage (p=0.001) and tumor recurrence (p=0.058) were considered significant. In multivariate analysis only tumor stage was significantly associated with overall survival (p=0.001). CONCLUSION: In this limited retrospective series, the ratio between positive and dissected lymph nodes was not independently associated with overall survival among patients with colon cancer, when considered together with the pathological stage. Larger and prospective studies are warranted to define the impact of such ratio on the overall survival of colon cancer patients.

RESUMO

PURPOSE: Patients with human epidermal growth factor receptor 2 (HER2) -positive metastatic tumors treated in the public health system in Brazil do not have access to trastuzumab. This study aimed to estimate the impact of the lack of access to anti-HER2 therapies on the mortality of these patients. METHODS: On the basis of published data, the number of patients with HER2-positive advanced breast cancer in 2016 who should receive anti-HER2 targeted therapy was estimated. Three different treatment groups were considered for this hypothetical cohort: chemotherapy alone, chemotherapy plus trastuzumab, and chemotherapy plus trastuzumab and pertuzumab. The number of patients alive after 2 years of follow-up was estimated on the basis of the efficacy results of the pivotal trials considering these interventions. RESULTS: It was calculated that 2,008 women will be diagnosed with advanced HER2-positive breast cancer in Brazil in 2016. It was estimated that only 808 women would be alive in 2018 if they receive only chemotherapy (which is the treatment offered by the public health system). On the other hand, the bar rises to 1,408 women alive in 2018 if they receive chemotherapy plus trastuzumab and 1,576 women alive in 2018 if they receive the gold standard of chemotherapy plus trastuzumab and pertuzumab. CONCLUSION: Trastuzumab is included in the WHO's list of essential medications, but the Brazilian public health system does not yet provide this treatment to its population with advanced disease. The introduction of trastuzumab and pertuzumab would have a positive effect, preventing premature deaths in women with metastatic HER2-positive breast cancer in Brazil.

RESUMO

ABSTRACTRecent advances in the understanding of tumor driver mutations, signaling pathways that lead to tumor progression, and the better understanding of the interaction between tumor cells and the immune system are revolutionizing cancer treatment. The pace at which new treatments are approved and the prices at which they are set have made it even more difficult to offer these treatments in countries like Brazil. In this review we present for the non-oncologist these new treatments and compare their availability in Brazilian public health system and private health system with that of developed countries.RESUMOAvanços recentes na compreensão de mutações promotoras de desenvolvimento do câncer, sinalização que leva à progressão de tumores, e o avanço no entendimento da interação entre as células tumorais e o sistema imunológico estão revolucionando o tratamento do câncer. A velocidade com que novos tratamentos são aprovados e o alto custo das medicações dificultam a disponibilização de terapêuticas em países como o Brasil. Nesta revisão, apresentamos ao não oncologista esses novos tratamentos e comparamos sua disponibilidade nos sistemas público e privado de saúde no Brasil com os países desenvolvidos.

RESUMO

OBJECTIVE: To evaluate the epidemiological profile and overall survival of a large population of elderly individuals diagnosed with solid tumors in a tertiary hospital. METHODS: This retrospective study included patients aged >65 years, diagnosed with solid tumors between January 2007 and December 2011, at Hospital Israelita Albert Einstein, São Paulo, Brazil. The medical records were reviewed to obtain information about clinical variables and overall survival. RESULTS: A total of 806 patients were identified, and 58.4% were male. Mean age was 74 years (65 to 99 years). The most common types were prostate (22%), colorectal (21%), breast (19%), and lung cancer (13%), followed by bladder (8%), pancreas (6%), and other types (11%). The majority of patients were diagnosed at early stage disease. After a median follow-up of 27 months (15 to 45 months), 29% of the patients (234/806) died, predominantly in the group older than 70 years. For the entire cohort, the median 2-year survival rate was 71%. Median overall survival was not reached within the study period. In a multivariate analysis, age (HR: 1.35; 95%CI: 1.25-1.45; p<0.001) and disease stage (HR: 1.93; 95%CI: 1.75-2.14; p<0.001) were independent negative predictors of poor survival. CONCLUSION: The most prevalent tumors were prostate, colorectal, breast, and lung cancer, with the larger proportion diagnosed at initial stages, reflecting the great number of patients alive at last follow-up.

RESUMO

OBJECTIVE: To estimate the prevalence of abnormal glomerular filtration rate in elderly patients with solid tumors. METHODS: A retrospective study with patients aged >65 years diagnosed with solid tumors between January 2007 and December 2011 in a cancer center. The following data were collected: sex, age, serum creatinine at the time of diagnosis and type of tumor. Renal function was calculated using abbreviated Modification of Diet in Renal Disease (MDRD) formulae and then staged in accordance with the clinical practice guidelines published by the Working Group of the National Kidney Foundation. RESULTS: A total of 666 patients were included and 60% were male. The median age was 74.2 years (range: 65 to 99 years). The most prevalent diagnosis in the study population were colorectal (24%), prostate (20%), breast (16%) and lung cancer (16%). The prevalence of elevated serum creatinine (>1.0mg/dL) was 30%. However, when patients were assessed using abbreviated MDRD formulae, 66% had abnormal renal function, stratified as follows: 45% with stage 2, 18% with stage 3, 3% with stage 4 and 0.3% with stage 5. CONCLUSION: To the best of our knowledge, this was the first study to estimate the frequency of renal insufficiency in elderly cancer patients in Brazil. The prevalence of abnormal renal function among our cohort was high. As suspected, the absolute creatinine level does underestimate renal function impairment and should not be used as predictor of chemotherapy metabolism, excretion and consequent toxicity.

RESUMO

PURPOSE OF THE STUDY: Diffuse large B-cell lymphoma (DLBCL) is the most common lymphoid malignancy worldwide. Its incidence increases with age and about 40% of cases occur in patients over 70 years. Herein, we describe a case of a frail elderly patient with renal insufficiency and DLBCL treated with R-mini-CHOP. CASE REPORT: A 77-year-old man on maintenance hemodialysis started experiencing persistent fatigue. He was diagnosed with a large mass on the left lobe of the lung. Biopsy demonstrated a DLBCL, CD20 positive. The patient was assigned clinical stage IIBX, with a high age-adjusted international prognosis index. A proper geriatric assessment revealed a frail patient. Thus, an adapted chemotherapy regimen was proposed which consisted of R-mini-CHOP every 21 days, with a reduction of 10% in the doses of doxorubicin and cyclophosphamide. During the treatment, the patient went through regular dialysis sessions, 3 times per week, with an extra session performed 12 h after each chemotherapy administration. The patient experienced no adverse events or grade 3/4 toxicities. After 6 cycles of R-mini-CHOP, the patient achieved unconfirmed complete remission, and consolidation radiotherapy was performed. At the last follow-up, he was still in unconfirmed complete remission, with a progression-free survival of 11.3 months. CONCLUSIONS: R-mini-CHOP represented a reasonable treatment option for this patient with renal failure. The oncogeriatric approach led to a successful management of this frail patient, highlighting that an adapted plan of care is a key issue to improve the outcomes of elderly cancer patients.

RESUMO

OBJECTIVE: To describe the flow and costs associated with the diagnosis and treatment of patients with breast cancer who come from the public healthcare system and were treated at Hospital Israelita Albert Einstein. METHODS: Between August 2009, and December 2011, 51 patients referred by the Unified Public Healthcare System (SUS) had access to Hospital Israelita Albert Einstein for diagnostic radiology, medical oncology, radiotherapy, and oncologic/breast reconstruction surgery. The data were collected retrospectively from the hospital records, patient charts, pharmacy records, and from the hospital billing system. RESULTS: The total sum spent for diagnosis and treatment of these 51 patients was US$ 1,457,500.00. This value encompassed expenses with a total of 85 hospitalizations, 2,875 outpatient visits, 16 emergency room visits, and all expenses associated with these stays at the hospital. The expenditure for treatment of each patient submitted to biopsy, breast conserving surgery, adjuvant chemotherapy without trastuzumab (a regime with taxane followed by anthracycline), radiotherapy, and 5 years of tamoxifen was approximately US$ 25,500.00. CONCLUSION: Strategies for cost-reduction of treatment in the private setting are necessary to enable future large-scale public-private partnerships in oncology.
