RESUMEN

BACKGROUND: Inguinal lymph node dissection plays an important role in the management of melanoma, penile and vulval cancer. Inguinal lymph node dissection is associated with various intraoperative and postoperative complications with significant heterogeneity in classification and reporting. This lack of standardization challenges efforts to study and report inguinal lymph node dissection outcomes. The aim of this study was to devise a system to standardize the classification and reporting of inguinal lymph node dissection perioperative complications by creating a worldwide collaborative, the complications and adverse events in lymphadenectomy of the inguinal area (CALI) group. METHODS: A modified 3-round Delphi consensus approach surveyed a worldwide group of experts in inguinal lymph node dissection for melanoma, penile and vulval cancer. The group of experts included general surgeons, urologists and oncologists (gynaecological and surgical). The survey assessed expert agreement on inguinal lymph node dissection perioperative complications. Panel interrater agreement and consistency were assessed as the overall percentage agreement and Cronbach's α. RESULTS: Forty-seven experienced consultants were enrolled: 26 (55.3%) urologists, 11 (23.4%) surgical oncologists, 6 (12.8%) general surgeons and 4 (8.5%) gynaecology oncologists. Based on their expertise, 31 (66%), 10 (21.3%) and 22 (46.8%) of the participants treat penile cancer, vulval cancer and melanoma using inguinal lymph node dissection respectively; 89.4% (42 of 47) agreed with the definitions and inclusion as part of the inguinal lymph node dissection intraoperative complication group, while 93.6% (44 of 47) agreed that postoperative complications should be subclassified into five macrocategories. Unanimous agreement (100%, 37 of 37) was achieved with the final standardized classification system for reporting inguinal lymph node dissection complications in melanoma, vulval cancer and penile cancer. CONCLUSION: The complications and adverse events in lymphadenectomy of the inguinal area classification system has been developed as a tool to standardize the assessment and reporting of complications during inguinal lymph node dissection for the treatment of melanoma, vulval and penile cancer.

RESUMEN

PURPOSE: A group of international urology and medical oncology experts developed and completed a survey on prostate cancer (PCa) in developing countries. The results are reviewed and summarized, and recommendations on consensus statements for very low-, low-, and intermediate-risk PCa focused on developing countries were developed. METHODS: A panel of experts developed more than 300 survey questions of which 66 questions concern the principal areas of interest of this paper: very low, low, and intermediate risk of PCa in developing countries. A larger panel of 99 international multidisciplinary cancer experts voted on these questions to create the recommendations for treatment and follow-up for very low-, low-, and intermediate-risk PCa in areas of limited resources discussed in this manuscript. RESULTS: The panel voted publicly but anonymously on the predefined questions. Each question was deemed consensus if 75% or more of the full panel had selected a particular answer. These answers are based on panelist opinion not a literature review or meta-analysis. For questions that refer to an area of limited resources, the recommendations consider cost-effectiveness and the possible therapies with easier and greater access. Each question had five to seven relevant answers including two nonanswers. The results were tabulated in real time. CONCLUSION: The voting results and recommendations presented in this document can be used by physicians to support management for very low, low, and intermediate risk of PCa in areas of limited resources. Individual clinical decision making should be supported by available data; however, as guidelines for treatment for very low, low, and intermediate risk of PCa in developing countries have not been developed, this document will serve as a point of reference when confronted with this disease.

RESUMEN

a) Objective: An increase in cell-free DNA was observed in the plasma of many cancer patients. This major biomarker can be used to differentiate patients with malignant neoplasms from those with benign neoplasms or healthy patients. Depending on the characteristic of the tumor, there are qualitative variations in the circulating cell-free DNA. Today, studies on the concentration of fragments of circulating cell-free DNA and their respective sizes in patients with bladder cancer are not plentiful in the literature. A 100% effective plasma tumor marker, which would help in the diagnosis and follow-up of bladder cancer, is yet to be developed; therefore, cell-free DNA levels in the plasma may represent a valuable biomarker for the diagnosis, prognosis and follow-up of patients with this type of tumor. b) Design and methods: In this study we analyze the kinetics of plasma and urine DNA concentrations in patients with bladder cancer, relating them to the other clinical laboratory variables. c) Results: Patients with hematuria showed a positive correlation with urine DNA. d) Conclusion: An increase in plasma and urine DNA was unprecedentedly reported over time, a fact that may come in handy in the prognosis of patients. Furthermore, microscopic haematuria is correlated with plasma and urinary DNA levels.

RESUMEN

OBJECTIVE: Prostate cancer is the most common nonskin cancer and second most common cause of cancer mortality in older men in the United States (USA) and Western Europe. Androgen-deprivation therapy alone (ADT) remains the first line of treatment in most cases, for metastatic disease. We performed a systematic review and meta-analysis of all randomized controlled trials (RCT) that compared the efficacy and adverse events profile of a chemohormonal therapy (ADT ± docetaxel) for metastatic hormone-naive prostate cancer (mHNPC). METHODS: Several databases were searched, including MEDLINE, EMBASE, LILACS, and CENTRAL. The primary endpoint was overall survival. Data extracted from the studies were combined by using the hazard ratio (HR) or risk ratio (RR) with their corresponding 95% confidence intervals (95% CI). RESULTS: The final analysis included 3 trials comprising 2,264 patients (mHNPC). Patients who received the chemohormonal therapy had a longer clinical progression-free survival interval (HR = 0.64; 95% CI: 0.55 to 0.75; p<0.00001), and no heterogeneity (Chi2 = 0.64; df = 1 [p = 0.42]; I2 = 0%). The biochemical progression-free survival (bPFS) also was higher in patients treated with ADT plus docetaxel (HR = 0.63; 95% CI: 0.57 to 0.69; p<0.00001), also with no heterogeneity noted (Chi2 = 0.48; df = 2 [p = 0.79]; I2 = 0%). Finally, the combination of ADT with docetaxel showed a superior overall survival (OS) compared with ADT alone (HR = 0.73; 95% CI: 0.64 to 0.84; p<0.0001), with moderate heterogeneity (Chi2 = 3.84; df = 2 [p = 0.15]; I2 = 48%). A random-effects model analysis was performed, and the results remained favorable to the use of ADT plus docetaxel (HR = 0.73; 95% CI: 0.60 to 0.89; p = 0.002). In the final combined analysis of the high-volume disease patients, the use of the combination therapy also favored an increased overall survival (HR = 0.67; 95% CI: 0.54 to 0.83; p = 0.0003). Regarding adverse events and severe toxicity (grade ≥3), the group receiving the combined therapy had higher rates of neutropenia, febrile neutropenia and fatigue. CONCLUSION: The combination of ADT with docetaxel improved the clinical progression-free survival, bPFS and OS of patients with mHNPC. A superior OS was seen especially for patients with metastatic and high-volume disease. This contemporary combination therapy may now be offered as a first-line treatment for selected patients.

RESUMEN

Priapism is a rare event that may be induced by clinical conditions and medications. Ischemic priapism (IP) is a compartment syndrome of the penis, and it constitutes a medical emergency that may cause significant morbidity on the erectile function in particular. We report a case of a 30-year-old male in his fourth episode of priapism. The aspiration and washing of the corpora cavernosa with saline solution were performed, followed by washing with adrenaline solution without resolution of the condition. Treatment was followed by the performance of the Al-Ghorab shunt procedure with dorsal incision of the glans. During follow-up, an area of necrosis distal to the incision was detected, and after the catheter removal on postoperative day 14, the patient developed a glandular dorsal urethrocutaneous fistula and meatal stenosis. The meatal stenosis was corrected by Johanson urethroplasty with a neo-meatus at the coronal sulcus, along with resection and debridement of the fistula tract and a three-layer closure.

RESUMEN

OBJECTIVES: To evaluate hyaluronan-mediated motility receptor (RHAMM) expression in normal, hyperplasic and neoplastic prostate tissue after various types and durations of androgen-deprivation therapy (ADT). Clinical and oncological data from men with localised prostate adenocarcinoma were also assessed and compared with RHAMM expression data. PATIENTS AND METHODS: Data from 367 men who underwent histological evaluation of the prostate were retrospectively evaluated under six conditions: (i) benign prostatic hyperplasia (BPH), (ii) BPH treated with finasteride, (iii) prostate cancer without ADT, (iv) prostate cancer treated with neoadjuvant ADT before prostatectomy (cyproterone 200 mg/day), (v) castration-resistant prostate cancer (CRPC), and (vi) normal peritumoral prostate tissue. Tissue microarrays were constructed and 1354 cores were evaluated for immunohistochemical RHAMM expression. RESULTS: There was no RHAMM expression in any tissue from normal patients or those with BPH or prostate cancer without ADT. There was RHAMM expression in 39.4% of prostate cancer tissues treated with ADT and in 46.2% of CRPC samples (P = 0.001). There was a significant increase in RHAMM expression with increased ADT duration in group 4, with a marked increase in RHAMM expression after 6-12 months of ADT (P = 0.04). No prognostic or clinical factors related to prostate cancer were associated with RHAMM expression. CONCLUSIONS: RHAMM expression in prostate cancer is directly associated with ADT. Significant RHAMM expression occurs as early as after 1 month of ADT and progressively increases with ADT duration. When prostate cancer becomes CRPC, RHAMM expression is higher. RHAMM expression was not associated with prostate cancer prognostic factors. RHAMM overexpression may contribute to the development of hormonal resistance in prostate cancer.
