RESUMO

BACKGROUND: Radiotherapy (RT) represents an alternative treatment option for patients with T1 squamous cell carcinoma of the penis (SCCP), with proven feasibility and tolerability. However, it has never been directly compared with partial penectomy (PP) using cancer-specific mortality (CSM) as an end point. METHODS: In the Surveillance, Epidemiology, and End Results database (2000-2020), T1N0M0 SCCP patients treated with RT or PP were identified. This study relied on 1:4 propensity score-matching (PSM) for age at diagnosis, tumor stage, and tumor grade. Subsequently, cumulative incidence plots as well as multivariable competing risks regression (CRR) models addressed CSM. Additionally, the study accounted for the confounding effect of other-cause mortality (OCM). RESULTS: Of 895 patients with T1N0M0 SCCP, 55 (6.1%) underwent RT and 840 (93.9%) underwent PP. The RT and PP patients had a similar age distribution (median age, 70 vs 70 years) and more frequently harbored grade I or II tumors (67.3% vs 75.8%) as well as T1a-stage disease (67.3% vs 74.3%). After 1:4 PSM, 55 (100%) of the 55 RT patients versus 220 (26.2%) of the 840 PP patients were included in the study. The 10-year CSM derived from the cumulative incidence plots was 25.4% for RT and 14.4% for PP. In the multivariable CRR models, RT independently predicted a higher CSM than PP (hazard ratio, 1.99; 95% confidence interval, 1.05-3.80; p = 0.04). CONCLUSION: For the T1N0M0 SCCP patients treated in the community, RT was associated with nearly a twofold higher CSM than PP. Ideally, a validation study based on tertiary care institution data should be conducted to test whether this CSM disadvantage is operational only in the community or not.

RESUMO

Purpose: To determine the quality of life (QoL) of patients with muscle-invasive bladder cancer (MIBC) who underwent bladder-sparing treatment with high-dose-rate brachytherapy, and compare their QoL with an age-matched general Dutch population. Material and methods: We conducted a single-center, prospective, descriptive cross-sectional study. MIBC patients who underwent brachytherapy-based bladder sparing treatment in Arnhem, The Netherlands from January 2016 to June 2021, were requested to complete the following questionnaires: European Organization for Research and Treatment of Cancer (EORTC) generic (QLQ-C30), bladder cancer-specific (QLQ-BLM30), and expanded prostate cancer index composite bowel (EPIC-50). Mean scores were calculated and compared with general Dutch population. Results: The mean global health status/QoL score of the treated patients was 80.6. High scores were noted in the functional scales, including physical (86.8), role (85.6), emotional (88.6), cognitive (88.3), and social functioning (88.9), while the main reported complains were related to fatigue (21.9) and urinary symptoms (25.1). Compared to the general Dutch population, significant differences were visible in global health status/QoL (80.6 vs. 75.7), pain (9.0 vs. 17.8), insomnia (23.3 vs. 15.2), and constipation (13.3 vs. 6.8). However, in no case did the mean score differ by more than ten points, which was considered clinically relevant. Conclusions: With a mean global health status/QoL score of 80.6, the patients after brachytherapy-based bladder sparing treatment have a good QoL. We found no clinically relevant difference in QoL comparing with an age-matched general Dutch population. The outcome strengthens the idea that this treatment option should be discussed with all patients eligible for brachytherapy-based treatment.

RESUMO

OBJECTIVE: To improve treatment outcomes in victims with kidney damage following blunt and stab abdominal trauma by using of minimally invasive methods of diagnosis and treatment. MATERIAL AND METHODS: About 1.2-3.5% of all victims arrived to the Dzhanelidze St. Petersburg Research Institute for Emergency Care have kidney injuries. We analyzed the results of treatment of 117 patients with isolated and combined blunt and stab abdominal injuries. The retrospective (2014-2017) group included 62 victims, and the prospective (2018-2021) group enrolled 55 patients who were treated according to the new algorithm. This algorithm included non-surgical and minimally invasive management for patients with systolic blood pressure >90 mm Hg after contrast-enhanced CT. Angiography with selective embolization was required for ongoing bleeding. We analyzed incidence of open interventions, organ-sparing procedures, complications, duration of treatment and mortality. Between-group differences were assessed using the χ2 test and Student's test. RESULTS: In both groups, kidney damage in most victims with abdominal trauma was due to road accident and catatrauma. Most patients had combined abdominal injuries, mainly in combination with head and chest lesions. Severity of injuries and clinical condition were similar in both groups. In the retrospective group, there were 9 laparotomies with nephrectomy. Nephrorraphy was performed in 8 cases, kidney vessel suture - in 4 patietns. In the prospective group, nephrectomy was performed in 3 patients with unstable hemodynamics and injuries AAST grade V. Nephrorraphy was performed in 4 victims. In one case, vascular suture was applied for tangential vein damage. All laparoscopies in both groups were diagnostic without nephrectomy. We used non-surgical treatment in 34 patients of the prospective group. One patient underwent angiography and selective embolization of renal artery branches. There were no significant between-group differences in the incidence of infectious and non-infectious complications. Mortality rate was 30.6% (n=19) and 27.3% (n=15) in the retrospective and prospective groups, respectively. CONCLUSION: The proposed algorithm for kidney injury made it possible to reduce the incidence of laparoscopies and laparotomies by 2 times, preserve the damaged kidney in 94.5% of cases and avoid invasive treatment in 62% of victims.

RESUMO

BACKGROUND: Penile cancer represents a rare malignant disease, whereby a small caseload is associated with the risk of inadequate treatment expertise. Thus, we hypothesized that strict guideline adherence might be considered a potential surrogate for treatment quality. This study investigated the influence of the annual hospital caseload on guideline adherence regarding treatment recommendations for penile cancer. METHODS: In a 2018 survey study, 681 urologists from 45 hospitals in four European countries were queried about six hypothetical case scenarios (CS): local treatment of the primary tumor pTis (CS1) and pT1b (CS2); lymph node surgery inguinal (CS3) and pelvic (CS4); and chemotherapy neoadjuvant (CS5) and adjuvant (CS6). Only the responses from 206 head and senior physicians, as decision makers, were evaluated. The answers were assessed based on the applicable European Association of Urology (EAU) guidelines regarding their correctness. The real hospital caseload was analyzed based on multivariate logistic regression models regarding its effect on guideline adherence. RESULTS: The median annual hospital caseload was 6 (interquartile range (IQR) 3-9). Recommendations for CS1-6 were correct in 79%, 66%, 39%, 27%, 28%, and 28%, respectively. The probability of a guideline-adherent recommendation increased with each patient treated per year in a clinic for CS1, CS2, CS3, and CS6 by 16%, 7.8%, 7.2%, and 9.5%, respectively (each p < 0.05); CS4 and CS5 were not influenced by caseload. A caseload threshold with a higher guideline adherence for all endpoints could not be perceived. The type of hospital care (academic vs. non-academic) did not affect guideline adherence in any scenario. CONCLUSIONS: Guideline adherence for most treatment recommendations increases with growing annual penile cancer caseload. Thus, the results of our study call for a stronger centralization of diagnosis and treatment strategies regarding penile cancer.

RESUMO

PURPOSE: To evaluate trimodal conservative treatment as an alternative to radical surgery for urothelial muscle-invasive bladder cancer (MIBC). PATIENTS AND METHODS: This retrospective study reported the carcinologic and functional results of patients (pts) presenting a cT2/T3 N0M0 operable MIBC and fit for surgery, treated by a conservative strategy. Treatment consisted of a transurethral resection (TURB) followed by concomitant bi-fractionated split-course radiochemotherapy (RCT) with 5FU-Cisplatine. A control cystoscopy was performed six weeks after the induction RCT (eq45Gy) with systematic biopsies. Patients with complete histologic response achieved RCT protocol. Salvage surgery was proposed to pts with persistent tumor. RESULTS: 313 pts (83% cT2 and 17% cT3) treated between 1988 and 2013 were included, with a median follow-up of 59 months and 67-year mean age. After the induction RCT, the histologic response rate was 83%. After five years, overall, disease-free, and functional bladder-intact survival rates were respectively 69%, 61%, and 69%, significantly better for pts in complete response after induction RCT. Late urinary and digestive toxicities were limited, with respective rates of 4% and 1.5% of grade 3 toxicity. CONCLUSION: Trimodal strategy with RCT after TURB showed interesting functional and oncologic results and should be considered as an alternative to surgery in well-selected pts.

RESUMO

BACKGROUND: Rectal cancer treatment advanced rapidly during last decades. The most important factors of this progress are new neoadjuvant therapy options, improvement in imaging (allowing for quality staging and restaging) and routine implementation of the total mesorectal excision technique. For the best outcomes, it is crucial to combine the treatment methods in the best way possible with ideal timing. It is necessary to keep in mind both advantages and complications of the individual kinds of approach. Therefore, interdisciplinary agreement is essential in the treatment of rectal cancer. Considering these new therapeutic possibilities, the debate about timing, indication and radicality of the surgical procedures is reopened. Surgical approaches are currently focused on mini-invasive methods and robotic surgery. New trend with promising potential seems to be clinical complete response achievement with watch and wait follow-up strategy. This approach, in the spirit of the organ sparing philosophy, however asks new questions about indication, timing and conception of this method. Proper answers are essential for sparing, yet radical oncotherapy of this disease.

RESUMO

OBJECTIVE: This study was conducted in order to determine the optimal timing of diffusion-weighted magnetic resonance imaging (DW-MRI) for prediction of pathologic complete response (pCR) to neoadjuvant chemoradiotherapy (nCRT) for esophageal cancer. METHODS: Patients with esophageal adenocarcinoma or squamous cell carcinoma who planned to undergo nCRT followed by surgery were enrolled in this prospective study. Patients underwent six DW-MRI scans: one baseline scan before the start of nCRT and weekly scans during 5 weeks of nCRT. Relative changes in mean apparent diffusion coefficient (ADC) values between the baseline scans and the scans during nCRT (ΔADC(%)) were compared between pathologic complete responders (pCR) and non-pCR (tumor regression grades 2-5). The discriminative ability of ΔADC(%) was determined based on the c-statistic. RESULTS: A total of 24 patients with 142 DW-MRI scans were included. pCR was observed in seven patients (29%). ΔADC(%) from baseline to week 2 was significantly higher in patients with pCR versus non-pCR (median [IQR], 36% [30%, 41%] for pCR versus 16% [14%, 29%] for non-pCR, p = 0.004). The ΔADC(%) of the second week in combination with histology resulted in the highest c-statistic for the prediction of pCR versus non-pCR (0.87). The c-statistic of this model increased to 0.97 after additional exclusion of patients with a small tumor volume (< 7 mL, n = 3) and tumor histology of the resection specimen other than adenocarcinoma or squamous cell carcinoma (n = 1). CONCLUSION: The relative change in tumor ADC (ΔADC(%)) during the first 2 weeks of nCRT is the most predictive for pathologic complete response to nCRT in esophageal cancer patients. KEY POINTS: • DW-MRI during the second week of neoadjuvant chemoradiotherapy is most predictive for pathologic complete response in esophageal cancer. • A model including ΔADCweek 2was able to discriminate between pathologic complete responders and non-pathologic complete responders in 87%. • Improvements in future MRI studies for esophageal cancer may be obtained by incorporating motion management techniques.

RESUMO

BACKGROUND: Active surveillance after neoadjuvant therapies has emerged among several malignancies. During active surveillance, frequent assessments are performed to detect residual disease and surgery is only reserved for those patients in whom residual disease is proven or highly suspected without distant metastases. After neoadjuvant chemoradiotherapy (nCRT), nearly one-third of esophageal cancer patients achieve a pathologically complete response (pCR). Both patients that achieve a pCR and patients that harbor subclinical disseminated disease after nCRT could benefit from an active surveillance strategy. SUMMARY: Esophagectomy is still the cornerstone of treatment in patients with esophageal cancer. Non-surgical treatment via definitive chemoradiotherapy (dCRT) is currently reserved only for patients not eligible for esophagectomy. Since salvage esophagectomy after dCRT (50-60 Gy) results in increased complications, morbidity and mortality compared to surgery after nCRT (41.4 Gy), the latter seems preferable in the setting of active surveillance. Clinical response evaluations can detect substantial (i.e., tumor regression grade [TRG] 3-4) tumors after nCRT with a sensitivity of 90%, minimizing the risk of development of non-resectable recurrences. Current scarce and retrospective literature suggests that active surveillance following nCRT might not jeopardize overall survival and postponed surgery could be performed safely. Key Message: Before an active surveillance approach could be considered standard treatment, results of phase III randomized trials should be awaited.

RESUMO

OBJECTIVES: To compare surgical outcomes between robot-assisted laparoscopic partial nephrectomy and open partial nephrectomy in patients with chronic kidney disease. METHODS: Of 550 patients who underwent partial nephrectomy between 2012 and 2015, 163 patients with T1-2 renal tumors who had an estimated glomerular filtration rate between 30 and 60 mL/min/1.73 m2 , and underwent robot-assisted laparoscopic partial nephrectomy or open partial nephrectomy were retrospectively analyzed. To minimize selection bias between the two surgical methods, patient variables were adjusted by 1:1 propensity score matching. RESULTS: The present study included 75 patients undergoing robot-assisted laparoscopic partial nephrectomy and 88 undergoing open partial nephrectomy. After propensity score matching, 40 patients were included in each operative group. The mean preoperative estimated glomerular filtration rate was 49 mL/min/1.73 m2 . The mean ischemia time was 21 min in robot-assisted laparoscopic partial nephrectomy (warm ischemia) and 35 min in open partial nephrectomy (cold ischemia). Preservation of the estimated glomerular filtration rate 3-6 months postoperatively was not significantly different between robot-assisted laparoscopic partial nephrectomy and open partial nephrectomy (92% vs 91%, P = 0.9348). Estimated blood loss was significantly lower in the robot-assisted laparoscopic partial nephrectomy group than in the open partial nephrectomy group (104 vs 185 mL, P = 0.0025). The postoperative length of hospital stay was shorter in the robot-assisted laparoscopic partial nephrectomy group than in the open partial nephrectomy group (P < 0.0001). The prevalence of Clavien-Dindo grade 3 complications and a negative surgical margin status were not significantly different between the two groups. CONCLUSIONS: In our experience, robot-assisted laparoscopic partial nephrectomy and open partial nephrectomy provide similar outcomes in terms of functional preservation and perioperative complications among patients with chronic kidney disease. However, a lower estimated blood loss and shorter postoperative length of hospital stay can be obtained with robot-assisted laparoscopic partial nephrectomy.

RESUMO

PURPOSE: Transanal endoscopic microsurgery (TEM) is a safe and efficient minimally invasive treatment for rectal benign and early malignant neoplasia, but postoperative complications may be severe. We aimed to evaluate the risk factors related to the incidence, severity, and time course of postoperative complications of TEM. METHODS: This is a prospective study of postoperative complications in 53 patients (>18 years old) with benign or early rectal neoplasia who underwent TEM with curative intention or, for higher stages, palliation. Outcome measures included age, sex, American Society of Anesthesiologists score, neoadjuvant chemoradiotherapy, lesion height and size, pathologic margins, tumor histology, and suture type. RESULTS: Overall morbidity was 50 %. Temporary fecal incontinence was the most frequent complication (17.3 %). Complication rates of Clavien-Dindo grades I and II were 21.1 % and those of grades III and IV 3.8 %. Of patients with complications, more had lesions under the first rectal valve than over the first valve (61.54 % vs 38.46 %, p = 0.04). Patients submitted to chemoradiotherapy had a 24-fold greater chance of presenting grade II complications (p = 0.002). When the surgical defect was treated using the TEM device to perform the suture, the chance of having grade III complications was reduced 16-fold (p = 0.04). Fifty-three percent of complications occurred in the first 10 days and 95 % within 20 days. CONCLUSIONS: Postoperative complications after transanal endoscopic microsurgery for the treatment of rectal neoplasia are frequent, acceptable, and usually controllable with pharmacologic treatment. Over time the nature of complications is continuous, centered on the first 20 days after surgery.

RESUMO

INTRODUCTION: Surgical treatment of penile cancer is usually associated with mutilation; alterations in self-esteem and body image; affecting sexual and urinary functions; and declined health-related quality of life. Recently, organ sparing treatment has appeared and led to limiting these complications. MATERIAL AND METHODS: An extensive review of the literature concerning penile-preserving strategies was conducted. The focus was put on indications, general principles of management, surgical options and reconstructive techniques, the most common complications, as well as functional and oncological outcomes. RESULTS: Analyzed methods, e.g.: topical chemotherapy, laser ablation therapy, radiotherapy, Moh's microscopic surgery, circumcision, wide local excision, glans resurfacing and glansectomy are indicated in low-stage tumors (Tis, Ta-T2). After glansectomy, reconstruction is also possible. CONCLUSIONS: Organ sparing techniques may achieve good anatomical, functional, and psychological outcomes without compromising local cancer control, which depends on early diagnosis and treatment. Penile sparing strategies are acceptable treatment approaches in selected patients with low-stage penile cancer after establishing disease-risk and should be considered in this population.

RESUMO

Few urologists deal with penile cancer on a daily basis. Owing to the rarity of the disease and its diversity in presentation, clinical experience accumulates slowly and new paradigms spread sporadically. This review provides a concise update on the background, clinical features and multidisciplinary management strategies of penile cancer. The evidence base of penile cancer management recommendations is devoid of randomized controlled trials and relies mainly on retrospective cohort studies from single institutions. In recent years, international multicentre collaboration has increased the quality of evidence. Larger study cohorts allow researchers to engage in subgroup analysis of patients with poor prognosis, of which the literature so far has been scarce. Comprehensive evidence-based guidelines are available through the European Association of Urology. This review highlights the importance of early and minimally invasive regional lymph-node staging of all patients of stage T1G2 or higher, and underlines the therapeutic potential of inguinal lymph-node dissection in lymph-node positive patients. A discussion of the oncological safety of current trends towards more phallus-sparing treatment techniques emphasizes the importance of proper case selection, thorough patient information, consequent follow-up and the possibility of a reconstructive procedure after organ-sparing ablative penile surgery. The aetiological role of human papilloma virus (HPV) is touched upon and the evidence for circumcision and HPV vaccination of boys is briefly weighed. The value of multidisciplinary treatment of advanced penile cancer is underlined and the role of chemotherapy, radiotherapy and radiochemotherapy is discussed. Finally, the perspectives for hybrid tracer sentinel node, robot-assisted lymph-node surgery and targeted therapies are addressed.

RESUMO

BACKGROUND: Proton beam radiotherapy (PBT) has shown to provide high radiation dose to tumors and to save surrounding normal tissues because of its physical characteristics, Bragg peak. In the current study, we report the early outcomes for pediatric patients with intracranial gliomas treated with PBT and compared PBT plan (pencil beam scanning and double scattering) with intensity modulated radiotherapy (IMRT) plan and three dimensional-conformal radiotherapy (3D-CRT) plan. METHODS: Clinical data from 18 consecutive children with intracranial gliomas who underwent PBT from May 2007 to April 2012 was collected. The median follow-up duration was 16 months (range 6-69). RESULTS: There were 9 patients with brain stem glioma, 2 patients with optic pathway glioma, 2 patients with low grade glioma (LGG), 2 patients with anaplastic astrocytoma (AA) and 3 patients with glioblastoma multiforme (GBM). The median overall survival for patients with brain stem glioma was 11 months. Patients with optic pathway glioma, LGG or AA were all alive without progression except one patient. Among patients with GBM, one patient had no evidence of disease 25 months after PBT. When PBT plan was compared to those of IMRT and 3D-CRT for patients with LGG or AA and one patient with brain stem glioma by DVH analysis, PBT showed better sparing effect on normal tissue compared to IMRT and 3D-CRT, especially in low dose area. CONCLUSION: PBT could be delivered safely and effectively to pediatric patients with gliomas. For confirming the clinical benefits of PBT, further follow-up is necessary.

RESUMO

Background: Cervical cancer is the most common cancer in female reproductive system. Since introduction of diagnostic modalities like Pap-tests, the detection pre-cancerous cervical lesions CIN1, CIN2 and CIN3 have increased dramatically. Early detection of pre-cancerous lesions enables performance of organ sparing treatments like LEEP, conization and cryotherapy.Aim: Since there are no studies in the field of organ sparing treatment of cervical cancer, we decided analyze the results of such treatments and calculate the:1. Five year survival of patients underwent organ sparing surgical procedures2. Fertility and reproductive function of these patientsMethod: LEEP (n-63), knife conization (n-22) and trachelectomy (total removal of cervix) (n-15) was performed in women of reproductive age (25-35 years old) at National Cancer Center. The treatment results were followed for 5 years and statistical analysis of survival and reproductive function were analyzed.Results: 87.7% of patients with CINI lesions had LEEP, 12.3 % had knife conization and 0% had trachelectomy. 44.4% of patients with CINI lesions had LEEP, 55.6 % had knife conization and 0% had trachelectomies respectively. For CINIII 6.2% of patients had LEEP, 0% had knife conization and 93% had trachelectomy.We performed organ sparing treatment in 100 patients, out of which 10% had cancer recurrence in LEEP treatment, 9.1% in knife conization and 0% in trachelectomy. Complications of hemorrhage were observed in 14% of patients, cervical tube obstruction in 3% and deterioration of chronic inflammations in 13% respectively. After the organ sparing treatment, menstrual cycle was normal in 75% of the all patients, 65% reached pregnancy. 9.2% of patients who reached pregnancy had stillbirth, 12.3% had abortion, and 78.5% had normal delivery. 80.4% of patients with pregnancy had natural labors, while19.6% of patients had ceasarean sections respectively. Conclusion: in Mongolia, LEEP, knife conization and trachelectomy methods are used since 2000. But the treatment results were not reported so far. 10% of patients treated by LEEP and 9.1% of patients treated by knife conization had tumor recurrence. Thus our treatment efficiency is above 90%. Up to 20% of patients had complications ranging from bleeding to cervical tube obstruction. We conclude that organ sparing cancer treatment allows better QOL (quality of life) for the patients and provides opportunity to have children.
