Neutrophil-to-lymphocyte ratio may be associated with the outcome in patients with prostate cancer
Purpose: Evidences have shown that neutrophil-to-lymphocyte ratio (NLR) has a prognostic value in patients with
cancer. We wanted to test the prognostic significance of NLR in prostatic cancer of patients who are candidate to radical
prostatectomy.
Methods: We have considered 731 patients. Complete demographic data including age, tumor stage, Gleason score,
complete blood count and serum biochemical profile were collected. Pre-treatment percentage of neutrophils and
NLR were considered, and correlated with patients data and recurrence free survival.
Results: 389 patients were evaluated, mean age 65 years, mean follow-up 51.5 months, mean recurrence free survival
51.3 months. Total neutrophil count does not correlate with biochemical recurrence and disease free survival.
Patients with a value higher of 60% of neutrophils are more likely to have a recurrence. Patients with a total lymphocyte
count <1,500 have a higher rate of relapse. NLR was not correlated with baseline total PSA, with Gleason score
and with pathological stage; patients with a NLR >3 has a higher incidence of recurrence. In multivariate analysis
including age, total PSA and NLR, NLR is the most important factor able to predict recurrence. There are some limitations
to this study; first, this is a retrospective study, and the total number of patients analyzed is relatively small.
Conclusions: Our study suggests that pre-treatment NLR may be associated with disease free survival in patients
with prostate cancer, and could be introduced in clinical practice. NLR has the advantage of low economic cost and
wide availability
Role of STAT3 pathway in genitourinary tumors
The STAT3 is often dysregulated in genitourinary tumors. In prostate cancer, STAT3 activation correlates with Gleason score and pathological stage and modulates cancer stem cells and epithelial-mesenchymal transition. In addition, STAT3 promotes the progression from carcinoma in situ to invasive bladder cancer and modulates renal cell carcinoma angiogenesis by increasing the expression of HIF1α and VEGF. STAT3 is also involved in the response to tyrosine kinase inhibitors sunitinib and axitinib, in patients with metastatic renal cell carcinoma, and to second-generation androgen receptor inhibitor enzalutamide in patients with advanced prostate cancer. In this review, we describe the role of STAT3 in genitourinary tumors, thus describing its potential for future therapeutic strategies
Controversial themes in liposuction: national opinion survey of members of the Brazilian Society of Plastic Surgery (Update Liposuction Survey)
INTRODUCTION: Liposuction is the second most commonly performed surgical procedure worldwide. However, many liposuction procedures are controversial. In this context, expert opinion surveys may help elucidate topics lacking consensus. The objective of this survey was to interview plastic surgeons who are members of the Brazilian Society of Plastic Surgery (Sociedade Brasileira de Cirurgia Plástica [SBCP]), the Update Liposuction Survey (ULS/SBCP), to assess their opinions about controversial topics in liposuction.
METHODS: A link to a questionnaire containing 11 questions involving liposuction (ULS/SBCP) was sent electronically to all SBCP members. The email was sent in three instances and with the provision of incentives to promote a higher response rate.
RESULTS: Of the 4,957 contacted plastic surgeons, 917 responded (response rate, 18.5%). The results are being analyzed for publication in full
Progress of Molecular Targeted Therapies for Advanced Renal Cell Carcinoma
Vascular endothelial growth factor (VEGF) plays a crucial role in tumor angiogenesis. VEGF expression in metastatic renal cell carcinoma (mRCC) is mostly regulated by hypoxia, predominantly via the hypoxia-induced factor (HIF)/Von Hippel-Lindau (VHL) pathway. Advances in our knowledge of VEGF role in tumor angiogenesis, growth, and progression have permitted development of new approaches for the treatment of mRCC, including several agents targeting VEGF and VEGF receptors: tyrosine kinase pathway, serine/threonine kinases, α5β1-integrin, deacetylase, CD70, mammalian target of rapamycin (mTOR), AKT, and phosphatidylinositol 3′-kinase (PI3K). Starting from sorafenib and sunitinib, several targeted therapies have been approved for mRCC treatment, with a long list of agents in course of evaluation, such as tivozanib, cediranib, and VEGF-Trap. Here we illustrate the main steps of tumor angiogenesis process, defining the pertinent therapeutic targets and the efficacy and toxicity profiles of these new promising agents
Risk of gastrointestinal events with sorafenib, sunitinib and pazopanib in patients with solid tumors: A systematic review and meta-analysis of clinical trials
Gastrointestinal (GI) events have been described with sorafenib, sunitinib and pazopanib in cancer patients. We performed an up-to-date meta-analysis to determine the incidence and relative risk (RR) in patients with cancer treated with these agents. PubMed databases were searched for articles published till May 2013. Eligible studies were selected according to PRISMA statement. Summary incidence, RR, and 95% CIs were calculated using random-effects or fixed-effects models based on the heterogeneity of selected studies. A total of 6,447 patients were available for the meta-analysis; 2,260 had renal cell carcinoma (RCC) and 4,187, 1,691 non-small cell lung cancers, 599 hepatocellular cancers, 1,066 breast cancers, 165 neuroendocrine tumors, 304 gastrointestinal stromal tumors and 362 soft tissue sarcomas. Diarrhea was the most common GI event. When stratified by tumor type (RCC vs. non-RCC), the difference among the incidences of GI events was significant for diarrhea (p < 0.001) and vomiting (p = 0.006), that resulted higher in RCC patients. In RCC patients, sorafenib registered the lower incidence and RR of all grades GI events. The difference was statistically significant for sorafenib versus sunitinib-related all and high-grade events (p < 0.001) and for sorafenib versus pazopanib all grades GI events (p < 0.001) and high-grade anorexia (p < 0.001). Treatment with VEGFR TKIs sorafenib, sunitinib and pazopanib is associated with a significant increase in the risk of GI events in patients with cancer, and frequent clinical monitoring should be emphasized when managing these three and newer VEGFR TKIs
Inside the 2015 ASCO Genitourinary Cancers Symposium
The American Society of Clinical Oncology (ASCO) Genitourinary Cancers Symposium, Rosen Shingle Creek, Orlando, FL, USA, 26-28 February 2015 The American Society of Clinical Oncology (ASCO) Genitourinary Cancers Symposium was held in Orlando (FL, USA), from 26 to 28 February 2015. This meeting was focused on 'Integrating Biology into patient-centric care' and represented an attractive opportunity for oncology professionals with a special interest in the diagnosis and treatment of genitourinary tumors. The identification and validation of biomarkers for tumor response had been the focus of several researchers at the symposium, together with the development of novel targeted agents. This report is a summary of the highlights on kidney and prostate tumors presented at the 2015 ASCO Genitourinary Cancers Symposium by various investigators
Seminoma Retroperitoneal Relapse 23 Years After Surgery
Stage I seminoma is the most frequent tumour in young men. It has a very good prognosis thanks to the use of a multidisciplinary therapeutic approach including surgery, radiotherapy and systemic chemotherapy. Late (after 2 years) and very late (after 5 years) relapses are uncommon, but not impossible, even if standardized follow-up for testicular tumours lasts up to 5 years after the diagnosis. We report a case of a 67-year-old Caucasian man with metachronous bilateral testicular seminoma who developed a retroperitoneal relapse of testicular seminoma 23 years after the first orchiectomy. Based on histological confirmation of testicular relapse, the patient underwent four cycles of systemic chemotherapy with bleomycin, etoposide and cisplatin (PEB), with no adverse reactions. He subsequently achieved complete radiological response at restaging computed tomography imaging, confirmed by the absence of glucose metabolism on positron emission tomography. In conclusion, this case report suggests the importance of longer standardized follow-up for patients treated for testicular tumours in order to detect earlier recurrence, which can be successfully treated
