Impact of salvage cytotoxic chemotherapy on prognosis in patients with recurrence after radical cystectomy: a multi-institutional retrospective study. BMC Urol 2022; 22:75. [PMID: 35549909 PMCID: PMC9103293 DOI: 10.1186/s12894-022-01026-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2021] [Accepted: 05/04/2022] [Indexed: 11/16/2022] Open
Abstract
Background In patients experiencing disease recurrence after radical cystectomy (RC) for bladder cancer, data about the impact of clinicopathologic factors, including salvage treatment using cytotoxic chemotherapy, on the survival are scarce. We investigated the prognostic value of clinicopathologic factors and the treatment effect of salvage cytotoxic chemotherapy (SC) in such patients. Methods In this retrospective study, we evaluated the clinical data for 86 patients who experienced recurrence after RC. Administration of SC or of best supportive care (BSC) was determined in consultation with the urologist in charge and in accordance with each patient’s performance status, wishes for treatment, and renal function. Statistical analyses explored for prognostic factors and evaluated the treatment effect of SC compared with BSC in terms of cancer-specific survival (CSS). Results Multivariate analyses showed that liver metastasis after RC (hazard ratio [HR] 2.13; 95% confidence interval [CI] 1.17 to 3.85; P = 0.01) and locally advanced disease at RC (HR 1.92; 95% CI 1.06 to 3.46; P = 0.03) are independent risk factors for worse CSS in patients experiencing recurrence after RC. In a risk stratification model, patients were assigned to one of two groups based on liver metastasis and locally advanced stage. In the high-risk group, which included 68 patients with 1–2 risk factors, CSS was significantly better for patients receiving SC than for those receiving BSC (median survival duration: 9.4 months vs. 2.4 months, P = 0.005). The therapeutic effect of SC was not related to a history of adjuvant chemotherapy. Conclusions The present study indicated the potential value of 1st-line SC in patients experiencing recurrence after RC even with advanced features, such as liver metastasis after RC and locally advanced disease at RC.

Cancer Manag Res 2020; 12:9003-9012. [PMID: 33061595 PMCID: PMC7522434 DOI: 10.2147/cmar.s258429] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2020] [Accepted: 08/21/2020] [Indexed: 12/21/2022] Open
Abstract
Purpose Spinal metastasis from urothelial carcinoma (UC) is relatively uncommon. The aim of the present study is to explore the clinicopathological features, surgical treatments and outcomes of this rare disease. Patients and Methods Fifteen patients with UC spinal metastasis who received surgery in our center between 2009 and 2018 were retrospectively investigated. Clinical data, treatment options, and outcomes were analyzed. Results For the 15 patients (9 men and 6 women), the primary tumors were located in the upper urothelial tract in ten and lower urothelial tract in five. UC mainly metastasized to the lumbar spine in seven cases, followed by the thoracic spine in five. Pathologic fracture and soft tissue mass with dura mater compression were observed in 66.7% and 93.3% cases, respectively. Palliative resection was performed in nine cases and excisional resection in six. Eleven patients received postoperative chemotherapy, including three with a preoperative ECOG score >2. Bisphosphonates were administered in all patients. Pain was relieved remarkably in all patients, and both the neurological function and general status were improved significantly after surgery. The median overall survival was 14 months. Log rank test showed that patients receiving postoperative chemotherapy survived longer than those without chemotherapy (p=0.037). WHO grade 3 was also correlated with poorer prognosis (p=0.012). Conclusion Pathological fracture and soft tissue mass with dura mater compression is frequently observed on radiological images in patients with UC spinal metastasis. Surgery is useful to prevent deterioration of performance status and improve quality of life, which provide an opportunity for further systematic therapy. Multimodal treatments, including surgery, postoperative chemotherapy and bisphosphonates are recommended. WHO grade 2 and receiving postoperative chemotherapy were favorable prognostic factors for the overall survival of patients with UC spinal metastasis.

Abstract
Management of urothelial bladder cancer has historically been challenging as a result of a limited grasp of disease biology and few available systemic therapy options, mainly consisting of platinum-based chemotherapy. Improved understanding of molecular mechanisms underlying pathogenesis of muscle-invasive bladder cancer as well as their correlation with tumor behavior and response to treatment has emerged over the past few years. Remarkable therapeutic advances have been made with the introduction of checkpoint inhibitors, which have changed the course of this disease. Multiple agents with novel mechanisms of action are also actively being explored in ongoing clinical trials. These advances are exciting but may prove challenging in terms of how to apply this constantly evolving plethora of data to actual patients. This review addresses the gray areas and challenging questions that frequently arise in clinical practice.

Abstract
Background Survival in patients with urothelial cancer (UC) recurrence after initial treatment with curative intent is limited and treatment options are sparse. Metastasectomy could be considered a treatment option in selected cases. Identifying prognostic factors for survival can be used to counsel patients and aid multidisciplinary teams in making treatment decisions. Methods We collected a retrospective case series of patients undergoing metastasectomy for oligometastatic UC between 1999 and 2018 at University Hospitals Leuven. Oligometastatic UC was defined as recurrence of UC in a single organ with ≤3 metastases. Survival outcomes of interest were: overall survival (OS), cancer-specific survival (CSS), and secondary recurrence-free survival (RFS2). Complications were reported using the Clavien-Dindo classification (CDC). Survival analysis are descriptive and were performed using Kaplan-Meier plots to visualize survival data and log-rank was used to compare survival between groups. Results From 1999 to 2018, a total of 22 patients underwent metastasectomy of oligometastatic UC. Metastasectomy sites were: pulmonary (59.1%), loco-regional (13.6%), hepatic (9.1%), adrenal (4.5%), testicular (4.5%), nodal above aortic bifurcation (4.5%), and renal transplant (4.5%). The 5-year OS, CSS and RFS2 after metastasectomy were 51.4%, 57.0%, and 49.9%, respectively. Patients with primary upper tract urothelial cancer (UTUC) involvement and patients treated with hepatic metastasectomy had a significantly worse OS, CSS, and RFS2. Patients with a lesion size >8 mm and patients with >1 pulmonary lesion had a significantly worse CSS. Two CDC grade 3B occurred during follow-up and were both non-procedure related. Conclusions Metastasectomy of oligometastatic UC is feasible and can achieve durable cancer control in a highly selected subgroup of patients. Our results suggest that patients with hepatic metastases or primary UTUC involvement could be considered poor candidates for metastasectomy, while patients with a small (<8 mm) or solitary pulmonary lesion might benefit most. These findings should be validated in multi-institutional collaborations or prospective clinical studies.

The Impact of Cisplatin- or Non-Cisplatin-Containing Chemotherapy on Long-Term and Conditional Survival of Patients with Advanced Urinary Tract Cancer. Oncologist 2019; 24:1348-1355.

Abstract
BACKGROUND The impact of cisplatin use on long-term survival of unselected patients with advanced urinary tract cancer (aUTC) has not been adequately investigated. We used a multinational database to study long-term survival and the impact of treatment type in unselected patients with aUTC. MATERIALS AND METHODS A total of 1,333 patients with aUTC (cT4bN0M0, cTanyN+M0, cTanyNanyM+), transitional-cell, squamous, or adenocarcinoma histology who received systemic chemotherapy and had available survival data were selected. Long-term survival was defined as alive at 3 years following initiation of first-line chemotherapy. Conditional overall survival (COS) analysis was employed to study change in prognosis given time survived from initiation of first-line chemotherapy. RESULTS Median follow-up was 31.7 months. The combination of cisplatin use and cisplatin eligibility accurately predicted long-term survival. Eligible patients treated with cisplatin conferred a 31.6% probability of 3-year survival (95% confidence interval [CI]: 25.1-38.3), and 2-year COS for patients surviving 3 years after initiation of cisplatin-based chemotherapy was 83% (95% CI: 59.7-93.5). The respective probabilities for patients who were ineligible for cisplatin or not treated with cisplatin despite eligibility were 14% (95% CI: 10.8-17.6) and 49.3% (95% CI: 28.2-67.4). Two-year COS remained significantly different between these two groups up to 3 years after chemotherapy initiation. CONCLUSION Cisplatin-based therapy was associated with the highest likelihood of long-term survival in patients with aUTC and should be used in patients who fulfill the established eligibility criteria. Novel therapies are necessary to increase long-term survival in cisplatin-ineligible patients. IMPLICATIONS FOR PRACTICE Long-term, disease-free survival is possible in one in four eligible-for-cisplatin patients with advanced urinary tract cancer (aUTC) treated with cisplatin-based combination chemotherapy. Therefore, deviations from eligibility criteria should be avoided. Consolidation surgery should be considered in responders. These data provide benchmarks for the study of novel therapies in aUTC.

Abstract
RATIONALE Several guidelines exist that address treatment of patients with nonmetastatic muscle-invasive bladder cancer (MIBC). However, most only briefly mention follow-up strategies for patients and hence the treating physician is often left to infer on what the preferred follow-up schema would be for an individual patient. Herein, we aim to synthesize recommendations for follow-up of patients with MIBC for easy reference. METHODS A multidisciplinary MIBC expert panel from the International Bladder Cancer Network was assembled to critically assess currently available major guidelines on surveillance of MIBC patients. Recommendations for follow-up were extracted and critically evaluated. Important considerations for guideline assessment included both aspects of oncological and functional follow-up-frequency of visits, the use of different imaging modalities, the role of cytology and molecular markers, and the duration of follow-up. OUTCOME An International Bladder Cancer Network expert consensus recommendation was constructed for the follow-up of patients with MIBC based on the currently available evidence-based data.

Abstract
AIM To clarify prognostic factors of metatstatic urothelial carcinoma treated by systemic chemotherapy in real-world clinical practice in the Japanese population. MATERIALS AND METHODS A total of 228 patients with metastatic urothelial carcinoma undergoing systemic chemotherapy between 2000 and 2013 were included in the present multi-institutional study. The gemcitabine plus cisplatin regimen was administered as first-line chemotherapy to 131 patients, whereas methotrexate, vinblastine, doxorubicin, and cisplatin or its modified regimen was given to 71 patients. Of the 228 patients, 119 received at least 2 different regimens and 22 underwent resection of metastases (metastasectomy). Multivariate survival analysis was performed using the Cox proportional hazards model. The characteristics included were age, sex, Eastern Cooperative Oncology Group performance status (PS), primary site, pathology of primary site, hemoglobin levels, lactate dehydrogenase levels, C-reactive protein levels, corrected calcium levels, estimated glomerular filtration rate levels, history of prior chemotherapy, metastatic sites, resection of primary site, number of metastatic organs, and metastasectomy. RESULTS The median overall survival (OS) time was 17 months. On multivariate analysis, female sex, good Eastern Cooperative Oncology Group PS at presentation, hemoglobin level≥10g/dl, and single organ metastasis were significant independent predictors of prolonged OS. For the survival effect of metastasectomy, the median OS time of the 22 patients with metastasectomy was 53 months, which was significantly longer when compared with patients not undergoing metastasectomy (15mo). After adjustment for the 4 aforementioned prognostic factors, metastasectomy still remained significant (hazard ratio: 0.364, P = 0.0008). CONCLUSIONS Female sex, more favorable PS at presentation, hemoglobin level>10g/dl, and single organ metastasis were favorable prognostic factors. In addition, metastasectomy was associated with long-term disease control.
