RESUMO

The diagnosis, treatment, and sequels of cancer are relevant sources of stress, conflicts, and suffering, but spirituality may be a positive coping element. However, studies involving the correlation between prostate cancer patients and spirituality are few and heterogeneous. MEDLINE (PUBMED), SCOPUS, and EMBASE were the databases used for this review with the keywords "spirituality," "religion," and "prostate cancer." The review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. About 250 articles were found, and 30 were eligible. Most studies (N = 26; 86.6%) reported the relationship between spirituality and better health findings such as 80% being positively associated with more screening for prostate cancer and better patients' quality of life. More interventional, randomized, and multicentric trials are needed to clarify this relationship.

RESUMO

INTRODUCTION: Germ-cell tumors (GCTs) are the most common malignancy in young men. There is a paucity of data on GCTs in developing countries. LACOG 0515 study aimed to evaluate clinical characteristics and treatment outcomes in patients with GCTs from Brazilian cancer centers. MATERIALS AND METHODS: This is a retrospective cohort study evaluating male patients diagnosed with GCTs from 2000 to 2018 in 13 Brazilian hospitals. We described baseline characteristics, progression-free survival (PFS), and overall survival (OS). RESULTS: A total of 1232 patients were included, with a median age of 30 years. Histology was seminoma in 47.1% and non-seminoma GCT (NSGCT) in 52.9%. The primary tumor site was testis in 96.5%. At diagnosis, clinical stage I was present in 68.1% and 34.7% and clinical stages IS/II/III in 31.9% and 65.2% of patients with seminoma and NSCGT, respectively. Following orchiectomy, 55.2% of patients with clinical stage I were managed with surveillance. The 5-year disease-free survival rates among patients with stage I were 98.0% in seminoma and 92.3% in NSGCT, with 5-year OS of 99.6% and 97.6%, respectively. Among patients with advanced disease (IS, II, and III), the 5-year PFS were 88.7% in seminoma and 68.7% in NSGCT, with 5y-OS of 97.6% and 82.8%, respectively. CONCLUSION: This is the largest Brazilian cohort of GCTs. Our results show a high rate of adjuvant chemotherapy in patients with clinical stage I. Although our data demonstrate slightly inferior PFS compared with the International Germ Cell Cancer Collaborative Group and other contemporary series, the OS rates were similar.

RESUMO

PURPOSE: To present a summary of the recommendations for the treatment and follow-up for the biochemical recurrence of castration-resistant prostate cancer (PCa) as acquired through a questionnaire administered at the Prostate Cancer Consensus Conference for Developing Countries. METHODS: A total of 27 questions were identified as relating to this topic. Responses from the clinician were tallied and are presented in percentage format. Topics included the use of imaging in staging, treatment recommendations across different patient scenarios of life expectancy and prostate-specific antigen (PSA) doubling time, and follow-up for nonmetastatic castration-resistant PCa. RESULTS: A consensus agreed that in optimal conditions, positron emission tomography-computed tomography with prostate-specific membrane antigen would be used although in limited resource situations the combined use of CT of the abdomen and pelvic (or pelvic MRI), a bone scan, and a CT of the thorax or chest x-ray was recommended. In cases when PSA levels double in < 10 months, more than 90% of clinicians agreed on the use of apalutamide or enzalutamide, regardless of life expectancy. With a doubling time of more than 10 months, > 54% of experts recommended no treatment independent of life expectancy. More than half of the experts, regardless of resources, recommended follow-up with a physical examination and PSA levels every 3-6 months and imaging only in the case of symptoms. CONCLUSION: The voting results and recommendations presented in this document can be used by physicians to support management for biochemical recurrence of castration-resistant PCa in areas of limited resources. Individual clinical decision making should be supported by available data.

RESUMO

Metastatic renal cell carcinoma (mRCC) encompasses a heterogeneous group of neoplasms with distinct clinical behavior and prognoses. As a result of the increasing number of therapeutic options in the metastatic setting, it is crucial to improve prognostic stratification ability. We aimed to evaluate the prognostic value of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and combination platelet count and neutrophil lymphocyte ratio (COP-NLR) in patients with mRCC. We evaluated a cohort of mRCC patients treated with first-line pazopanib or sunitinib. Levels of NLR, PLR and COP-NLR were measured prior to systemic treatment and evaluated as prognostic predictors. Primary endpoint was overall survival (OS). Data from 276 patients were included, of which 54.7% received first-line pazopanib and 45.3%, sunitinib. Memorial Sloan-Kettering Cancer Center risk classification was intermediate and poor in 50% and 42.6% of patients, respectively. High NLR (> 3.5) was associated with inferior OS (median 9.6 vs 17.8 months, P < 0.001). A high PLR (> 200) was associated with inferior OS (median 10.3 vs 17 months, P = 0.002). The median OS in the COP-NLR 1, 2 and 3 groups were 19.0 months (95% CI 15.3-26.0), 13.1 months (95% CI 9.8-17.0) and 7.4 months (95% CI 3.6-11.9), respectively (P < 0.001). In the multivariate analysis, high NLR and high COP-NLR were associated with inferior OS. Both high NLR and high COP-NLR were associated with poorer OS in our cohort of patients with mRCC treated with first-line pazopanib or sunitinib.

RESUMO

PURPOSE: Reported treatment outcomes for patients with advanced germ cell tumors (aGCT) are based mainly on series from developed nations. Data from low- and middle-income countries are underrepresented. MATERIAL AND METHODS: From 2000 to 2015, a retrospective analysis identified 300 patients with aGCT treated at our institution. Kaplan-Meier methods were used for analysis of progression-free survival (PFS) and overall survival (OS) according to the International Germ Cell Consensus Classification Group (IGCCCG). RESULTS: Patients' median age was 28 years. According to the IGCCCG, 57% had good-, 18.3% intermediate-, and 24.7% poor-risk disease. Median α-fetoprotein levels were 2.9, 243, and 3,998 ng/mL, and those of human chorionic gonadotropin were 0.4, 113, and 301.5 mUI/mL in IGCCCG good-, intermediate-, and poor-risk groups, respectively. At a median 46 months of follow-up, 93 PFS events and 45 deaths had occurred and estimated 5-year PFS and OS were 69% and 85%, respectively, including 83% and 95.3% in good-risk, 70.9% and 83.6% in intermediate-risk, and 35.1% and 62.2% in poor-risk patients, respectively. In multivariable analysis, Eastern Cooperative Oncology Group performance status ≥ 2 was a significant independent prognostic factor with a hazard ratio of 2.58 (95% CI, 1.55 to 4.29; P < .001) and 6.20 (95% CI, 2.97 to 12.92; P < .001) for PFS and OS, respectively. CONCLUSION: Brazilian patients with aGCT in this cohort had similar outcomes as patients in the IGCCCG database. In comparison with contemporary series, patients with intermediate- and poor-risk aGCT had slightly inferior PFS and OS, possibly due to a high percentage of patients with poor performance status and less use of high-dose chemotherapy.

RESUMO

INTRODUCTION: Non-clear cell renal cell carcinoma (nccRCC) and sarcomatoid renal cell carcinoma (sRCC) are underrepresented in clinical trials. Treatment approaches are frequently extrapolated from data of clear cell renal cell carcinoma, in which pazopanib is non-inferior to sunitinib. We aim to compare the effectiveness of first-line sunitinib and pazopanib for nccRCC and sRCC. METHODS: We evaluated a retrospective cohort of patients with metastatic nccRCC and sRCC treated with first-line sunitinib or pazopanib at an academic cancer centre. Overall survival (OS), progression-free survival (PFS) and response rate were measured. Kaplan-Meier and log-rank analyses were used for time-to-event data. Cox regression was used for prognostic factors. RESULTS: Fifty-three patients were included; 16 (30.1%) treated with sunitinib and 37 (69.9%) with pazopanib. Forty-six (86.8%) patients had nccRCC and 7 (13.2%) had sRCC. The majority had intermediate or poor International Metastatic Renal-Cell Carcinoma Database Consortium risk (93%).Median PFS was 6.6 months with sunitinib and 4.9 months with pazopanib (HR 1.75; P = 0.078). Treatment with pazopanib was associated with inferior OS in comparison with sunitinib (median OS: 30.4 months versus 8.7 months; HR 2.71, 95% CI 1.31-5.58, P = 0.007). These results were confirmed in subgroup analysis of patients with papillary, chromophobe and MiT family translocation histologies (median OS: 38.7 months versus 14.7 months; HR 3.16, 95% CI 1.20-8.29, P = 0.019). Unclassified and sarcomatoid histologies had inferior OS (median: 6.9 and 1.1 months, respectively) regardless of the treatment used. CONCLUSION: In this patient cohort, pazopanib was associated with inferior OS in comparison with sunitinib for metastatic nccRCC. Larger trials are ideally warranted to confirm these results.

RESUMO

PURPOSE: Limited data are available about the tolerability and clinical outcomes of elderly patients with metastatic castration-resistant prostate cancer (mCRPC) who are treated with docetaxel. We evaluated the efficacy and safety of docetaxel as first-line chemotherapy for patients with mCRPC who were treated in our institution. MATERIALS AND METHODS: We retrospectively identified patients with mCRPC and a Karnosfky performance status of 60% or greater treated with docetaxel on any schedule as first-line chemotherapy between 2008 and 2013. The primary end point was a comparison of median overall survival (OS) according to age in this population. Secondary end points were comparisons of the rates of severe toxicities, prostate-specific antigen (PSA) decline of 50% or greater, and time to progression (TTP). Results were stratified by three age groups: younger than 65 years, 65 to 74 years, and 75 years or older. RESULTS: Among the 197 patients included, 68 (34%) were younger than 65 years, 85 (43%) were 65 to 74 years, and 44 (22%) were 75 years or older. The mean number of comorbidities was not different among groups (1.19 v 1.32 v 1.43; P = .54). Patients younger than 65 years received a higher cumulative dose of docetaxel (450 mg/m2 v 382 mg/m2 v 300 mg/m2; P = .004). The rates of PSA decline of 50% or greater (41% v 47% v 36.4%; P = .51) and the median TTP (5.13 v 5.13 v 4.7 months; P = .15) were comparable among all groups. The median OS was longer in the group of patients younger than age 65 years (19.6 v 12.4 v 12.3 months; P = .012). Rates of any grade 3 or higher adverse event were not different among groups (63.2% v 71.8% v 54.5%; P = .14). CONCLUSION: Administration of docetaxel in elderly patients who had good performance status was well tolerated. Rates of PSA decline and TTP were similar to those of younger patients, but median survival was lower.

RESUMO

Purpose Sunitinib and pazopanib are multitargeted tyrosine kinase inhibitors (TKIs) that act against vascular endothelial growth factor receptors and are standard first-line treatment options for metastatic clear cell renal cell carcinoma (ccRCC). The Brazilian public health system diverges from the randomized clinical trials in the availability of first and subsequent lines of treatment and in clinical and demographic characteristics of patients. Therefore, it is essential to describe the history of advanced ccRCC during and after TKI treatment in this population. Methods We performed a retrospective analysis of patients with advanced ccRCC treated with a first-line TKI (either sunitinib or pazopanib) between February 2009 and March 2017 in a single academic Brazilian cancer center (Instituto do Câncer do Estado de São Paulo). Results Of the 222 patients, 109 were treated with sunitinib and 113 with pazopanib. The median duration of treatment and overall survival (OS) were 6.4 and 15.2 months for sunitinib and 6.7 and 14.2 months for pazopanib, respectively. Discontinuation of treatment occurred secondarily to progressive disease or death in 64.2% of patients using sunitinib and in 54.8% of patients using pazopanib. Adverse events were responsible for discontinuation of treatment in 28.4% of patients in the sunitinib group and in 22.1% in the pazopanib group. According to Memorial Sloan-Kettering Cancer Center risk categories, the OS was 32.9 months, 15.9 months, and 8.1 months for low risk, intermediate risk, and poor risk, respectively (hazard ratio, 1.72; 95% CI, 1.13 to 2.26; P < .001). Conclusion The use of TKI inhibitors as first-line treatment of metastatic RCC is effective and feasible in the Brazilian public health. However, the median OS of our population is considerably lower compared with the prospective trials that evaluated the same drugs.

RESUMO

BACKGROUND: In renal cell carcinoma (RCC) of the clear cell type, inactivity of the VHL gene induces overexpression of HIF1 α and its targets, the tyrosine kinase receptors, promoting RCC development and progression. The discovery of tyrosine kinase inhibitors (TKIs) changed the treatment of these tumors. Other molecular pathways involved in the TKI mechanisms of action have not been described in the literature. The aim of our study was to elucidate alternative mechanisms of action of sunitinib in tumor tissue after neoadjuvant treatment of RCC. METHODS: The gene expression profile was accessed using microarray (Affymetrix Human Genome U133 Plus 2.0 platform) and frozen RCC tissues collected from 5 patients with locally advanced non-metastatic tumors who underwent nephrectomy after being treated with 2 cycles of neoadjuvant sunitinib. The results were compared with matched controls comprising 6 patients with no neoadjuvant intervention. RESULTS: There was underexpression of the majority of genes after sunitinib treatment. The lower expression levels of IGFBP1, CCL20, CXCL6 and FGB were confirmed by qRT-PCR in all cases. The downregulation of gene expression leads us to search for methylation as a mechanism of action of the TKI. IGFBP1 was shown to be methylated by methylation-sensitive high-resolution melting technique. CONCLUSIONS: The ultimate genetic effects of sunitinib may explain its actions as an antitumor drug that apparently suppresses the expression of important genes related to cell survival, adhesion, invasion and immunomodulation. The methylation of gene promoters was shown to be part of the mechanism of action of this class of drugs.

RESUMO

We evaluated the efficacy and safety of metronomic oral cyclophosphamide (CTX) and prednisone in metastatic castration-resistant prostate cancer (mCRPC) patients. We analyzed retrospectively patients with mCRPC previously treated with docetaxel, and who received metronomic CTX (from 50 mg PO daily to 150 mg PO, 14 days/7 days off) and prednisone 10 mg PO daily between September 2009 and April 2014 were analyzed. The primary endpoint was prostate-specific antigen (PSA) decrease ≥50 %. Secondary analysis included PSA decrease ≥30 %, time-to-treatment failure (TTF) and toxicity. Demographics and baseline characteristics were summarized using descriptive statistics. PSA response and adverse events were reported as relative rates. Kaplan-Meier estimates were calculated and plotted for time-to-event endpoints. Forty patients were evaluated. The median age was 69 years old (52-86), 12 (30.0 %) patients presented a Karnofsky performance status (KPS) of <80 %, and 34 (85 %) presented with bone with or without nodal metastases. Median pre-treatment PSA was 192 ng/dL (7-2696 ng/dL). All patients were previously exposed to docetaxel, including 33 (82.5 %) with docetaxel-refractory disease. PSA response rate was achieved in eight (20.0 %) out of 40 patients. Additionally, PSA declines of ≥30 % occurred in 14 (35.0 %) patients. The median TTF was 3 months (95 % confidence interval 2.5-3.5). The treatment was well tolerated. Grade 3/4 lymphopenia was reported in 11 (27.5 %) patients and was the only grade 3-4 toxicity reported. Metronomic oral CTX showed activity and safety in docetaxel-pretreated mCRPC patients. This regimen deserves further investigation in this setting.

RESUMO

Purpose To assess the activity, safety and treatment patterns of sunitinib in patients with poor-risk metastatic renal cell carcinoma (mRCC). Materials and Methods We retrospectively reviewed the charts of poor risk patients treated with sunitinib from October 2006 to July 2013 who met the eligibility criteria. The primary endpoint was overall survival (OS). Tumor radiological response was measured according to RECIST 1.1 and adverse events (AEs) were assessed through standard criteria. Results Median OS was 8.16 months (95% CI, 5.73-10.59). Of the 53 patients included in this analysis, 9 (17.0%) achieved partial response, 12 (22.6%) had stable disease. Median treatment duration was 3.30 months (95% CI: 1.96-4.63) and 26.4% of patients discontinued treatment due to toxicity. Grade 3 or higher AEs occurred in 39.6% of patients, the most common being fatigue (15.1%), neutropenia (9.5%), nausea, vomiting and diarrhea (7.5% each). Discussion Sunitinib may benefit some unselected poor-risk patients, although the rates of AEs and drug discontinuation suggest a need for careful patient monitoring. .

RESUMO

The treatment landscape of castration-resistant prostate cancer (CRPC) has been dramatically changed over the past years with the approval of several new drugs for clinical use. These include androgen axis-targeted therapy and novel drugs with different mechanisms of action, including immunotherapy (sipuleucel-T), radiopharmaceuticals (radium-223), and chemotherapy (cabazitaxel). Based on the growing knowledge that the main driver for patients progressing on standard androgen deprivation therapy is persistent activation of the androgen receptor (AR) signaling axis, new drugs were developed and demonstrated significant efficacy in recent clinical trials, leading to the approval of abiraterone and enzalutamide in several countries. In this article, we review the most recent advances in AR-directed therapies for CRPC, promising new agents under development, cross-resistance, and mechanisms of resistance for the new-generation AR-targeted agents.

RESUMO

Adenocarcinoma of the seminal vesicle is a rare condition, with fewer than 60 cases described in the literature. Most reports highlight the histopathological characteristics of the tumor; however, the role of chemotherapy, especially in the metastatic setting, is poorly described. In this paper, we describe a patient with metastatic disease, who sustained a response to modified FOLFOX6 as first-line therapy. This platinum-based combination therapy seems effective in this scenario and may provide an opportunity for extended survival and relief of symptoms.

RESUMO

Renal medullary carcinoma (RMC) is rare, accounting for less than 1% of all renal neoplasms. Case reports suggest RMC is highly aggressive, poorly responsive to chemotherapy, often metastatic at diagnosis, affects young men with sickle cell trait, and median overall survival (mOS) is less than 12 months. We report the epidemiological characteristics, treatments performed, response rate to each treatment and mOS of five patients with RMC. All patients had sickle cell trait, four were male, three had metastatic disease at diagnosis and mean age at diagnosis was 25 years. Non-metastatic patients were submitted to nephrectomy. Two patients had partial response to first line chemotherapy including cisplatin and gemcitabine. There was no response to sunitinib or second line chemo - therapy; mOS was 6 months. Due to its rarity, case series are the only evidence available to discuss the treatment for RMC. In our experience, only cisplatin and gemcitabine based regimen offered response.

RESUMO

O adenocarcinoma de próstata é o câncer mais comum no sexo masculino após o câncer de pele. Dentre as várias formas de tratamento do câncer de próstata, a terapia de bloqueio androgênico é uma modalidade consagrada nos pacientes com doença metastásica ou localmente avançada, e que provavelmente resulta em aumento de sobrevida. No entanto, o bloqueio androgênico é causador de uma série de consequências adversas. Complicações como osteoporose, disfunção sexual, ginecomastia e anemia são bem conhecidas. Recentemente uma série de complicações metabólicas foi descrita, como aumento da circunferência abdominal, resistência à insulina, hiperglicemia, diabetes, dislipidemia e síndrome metabólica, com consequênte aumento do risco de eventos coronários e mortalidade cardiovascular nessa população específica.


Prostate adenocarcinoma is the most prevalent cancer in men after skin cancer. Between the various prostate cancer treatment modalities, androgen deprivation is a recognized modality in patients with metastatic or locally advanced disease, which likely improves survival. However, androgen deprivation is a cause of important side effects. Complications such as osteoporosis, sexual dysfunction, gynecomastia and anemia are well known. Recently, a series of metabolic complications have been reported such as increased abdominal circumference, insulin resistance, diabetes, dyslipidemia and metabolic syndrome, leading to an increase in coronaries events and cardiovascular mortality in this specific population.
