RESUMEN

Although renal graft percutaneous embolization was introduced to avoid the risk associated with graft nephrectomy, there is no universal consensus about its indications and results. In order to evaluate the efficacy of graft embolization in the treatment of graft intolerance syndrome as well as its safety compared to surgical removal with respect to complications and other morbidity measures, We performed a retrospective observational study comparing two groups of patients treated for graft intolerance syndrome: Group 1: patients who had embolization as first-line treatment and Group 2: patients directly treated by surgical removal. 72 patients were included, (32 in Group 1 and 40 in Group 2); the postintervention follow-up continued for 12 months. Patients in Group 1 are older than those in Group 2. Otherwise, the two groups are similar concerning sex, manifestations of graft intolerance syndrome, diabetes and nutritional and functional status. The overall success rate of embolization in complete resolution of graft intolerance syndrome and ultimately avoidance of surgical removal was 84.37%. The surgical removal group had more serious complications, a longer hospital stay and needed more blood transfusions. We conclude that embolization of symptomatic renal grafts has considerable efficacy with less morbidity, and no serious complications compared to the standard surgical graft removal.

RESUMEN

BACKGROUND: Prostate cancer is the most common cancer in male in most Western countries, including France. Despite a significant morbidity and mortality to a lesser extent, the etiology of prostate cancer remains largely unknown. Indeed, the only well-established risk factors to date are age, ethnicity and a family history of prostate cancer. We present, here, the rationale and design of the EPIdemiological study of Prostate CAncer (EPICAP), a population-based case-control study specifically designed to investigate the role of environmental and genetic factors in prostate cancer. The EPICAP study will particularly focused on the role of circadian disruption, chronic inflammation, hormonal and metabolic factors in the occurrence of prostate cancer. METHODS/DESIGN: EPICAP is a population-based case-control study conducted in the département of Hérault in France. Eligible cases are all cases of prostate cancers newly diagnosed in 2012-2013 in men less than 75 years old and residing in the département of Hérault at the time of diagnosis. Controls are men of the same age as the cases and living in the département of Hérault, recruited in the general population.The sample will include a total of 1000 incident cases of prostate cancer and 1000 population-based controls over a 3-year period (2012-2014).The cases and controls are face-to-face interviewed using a standardized computed assisted questionnaire. The questions focus primarily on usual socio-demographic characteristics, personal and family medical history, lifestyle, leisure activities, residential and occupational history. Anthropometric measures and biological samples are also collected for cases and controls. DISCUSSION: The EPICAP study aims to answer key questions in prostate cancer etiology: (1) role of circadian disruption through the study of working hours, chronotype and duration/quality of sleep, (2) role of chronic inflammation and anti-inflammatory drugs, (3) role of hormonal and metabolic factors through a detailed questionnaire, (4) role of individual genetic susceptibility of genes involved in biological pathways of interest. The EPICAP study will also allow us to study prognostic factors and tumor aggressiveness.Taken together, the EPICAP study will provide a comprehensive framework to go further in the understanding of prostate cancer occurrence and its prognosis.

RESUMEN

OBJECTIVES: To determine the impact of renal graft nephrectomy on second kidney transplantation survival. METHODS: We carried out a retrospective single-center study by analyzing cases performed from January 2000 to December 2011. Retransplanted patients who underwent previous allograft nephrectomy more than 3 months post-transplantation (group 1) were compared with those who did not (group 2) in terms of graft survival, incidences of acute rejection and delayed graft function. Multivariate Cox proportional hazard models were used to assess risk factors of graft loss after retransplantation. RESULTS: Overall, 146 patients were analyzed, including 52 (35.6%) in group 1 and 94 (64.4%) in group 2. Group 1 patients presented a significantly shorter first graft survival (0.8 vs 8.6 years, P < 0.001) and more anti-class I antibodies (90.5% vs 74.2%, P = 0.03). A total of 10 patients (19%) in group 1 and 16 patients (17%) in group 2 had at least one acute rejection episode (P = 0.74). Delayed graft function was observed in 13 patients (25%) in group 1 and 17 patients (18%) in group 2 (P = 0.32). Graft survival at 1, 5 and 10 years was, respectively, 94%, 81% and 58% in group 1, and 99%, 93% and 66% in group 2 (P = 0.10). Graft survival was decreased by increased donor age and serum creatinine, and tended to be associated with post-transplantation presence of anti-class I and II antibodies. Graft nephrectomy was not associated with graft survival in multivariate analysis. CONCLUSIONS: Graft nephrectomy, probably a marker of high immunological risk patients, is not a risk factor of increased retransplant failure.

RESUMEN

PURPOSE: The association between marital status and tumor stage and grade, as well as overall mortality (OM) and cancer-specific mortality (CSM) received little attention in patients with squamous cell carcinoma of the penis (SCCP). METHODS: We relied on the surveillance, epidemiology, and end results (SEER) 17 database to identify patients diagnosed with primary SCCP. Logistic and Cox regression models, respectively, addressed the effect of marital status on the rate of locally advanced disease and its effect on OM and CSM. Covariates consisted of age, race, socioeconomic status, year of surgery, and SEER registries. RESULTS: Between 1988 and 2006, 1,884 patients with SCCP were identified. At surgery, 1,192 (63.3 %) were married and 966 (51.3 %) had locally advanced disease. In multivariable logistic regression models predicting locally advanced disease at surgery, unmarried men had a 1.5-fold higher (p < 0.001) risk than others. In multivariable Cox models predicting CSM, marital status had no effect [hazard ratio (HR) = 1.3, p = 0.1]. Finally, in multivariable Cox models predicting OM, unmarried men had a 1.3-fold higher (p = 0.001) risk than others. CONCLUSION: Unmarried men tend to present with less favorable disease stage at SCCP. Moreover, unmarried men tend to live less long than their married counterparts. However, marital status has no effect on CSM.

RESUMEN

OBJECTIVE: To quantify and compare cancer-specific mortality (CSM) and other-cause mortality (OCM) in individuals with stage T1G1-3 clinically node-negative (cN0) squamous cell carcinoma of the penis (SCCP) since there is no consensus regarding the need for an inguinal lymph node dissection (ILND) in patients with T1G2-3 cN0 SCCP. METHODS: Relying on the Surveillance, Epidemiology and End Results database, we identified 655 patients diagnosed with primary SCCP between 1988 and 2006. Cumulative incidence plots were used to graphically depict the effect of CSM relative to OCM. Competing-risks regression analyses were used to quantify the risk of CSM or OCM after adjusting for age, race, tumour grade and surgery type. RESULTS: The 5-year CSM rates after a primary tumour excision without ILND were 2.6%, 10.0% and 15.9% in patients with respectively T1G1, T1G2 and T1G3 cN0 SCCP. The 5-year OCM rates were 29.5%, 27.3% and 29.3% in patients with respectively T1G1, T1G2 and T1G3. Age failed to provide additional stratification. CONCLUSIONS: The CSM rate was highest in T1G3 patients and appears to justify ILND. Conversely, the CSM rate was lowest in T1G1 patients, which justifies active surveillance in this patient subset. A moderate CSM rate at 5 years was recorded for T1G2 patients, which brings into question the benefits of ILND.

RESUMEN

BACKGROUND: Conditional survival (CS) implies that, on average, long-term cancer survivors have a better prognosis than newly diagnosed individuals. The objective of the current study was to devise an accurate predictive tool that accounts for CS in men diagnosed with penile cancer. METHODS: Overall, 1245 patients treated with primary tumor excision (PTE) for pT(1-3)M0 squamous cell carcinoma of the penis (SCCP) between 1998 and 2006 were identified. Cox regression models were fitted for prediction of cancer-specific mortality (CSM). Nomogram development for prediction of CSM using CS methodology at 2 and 5 years was performed on 670 patients. External validation and calibration of the conditional nomogram was performed in 575 patients. RESULTS: The 5-year CSM-free survival of patients at surgery was 84.3% and increased to 95.0% and 97.8% after 2 and 5 years of disease-free survival (DFS), respectively. The predicted probabilities varied by as much as 49% (57% vs 85%) when, for example, predictions of CSM-free survival at 5 years were made after PTE versus after 2 years of DFS. Within the external validation cohort, the accuracy of the conditional nomogram was 75.3% and 78.1% at 2 and 5 years after PTE. CONCLUSIONS: The authors developed and externally validated the first conditional nomogram for predicting SCCP CSM-free survival that allows consideration of the length of survivorship.

RESUMEN

PURPOSE: Penile cancer is rare. Thus, predicting cancer specific mortality may be difficult. We devised an accurate and yet easily applicable predictive rule that compares favorably with 2 previous models (73.8% and 74.7% accuracy, respectively). MATERIALS AND METHODS: We identified patients treated with primary tumor excision for all stages of penile squamous cell carcinoma between 1998 and 2006. Disease stage definitions using Surveillance, Epidemiology and End Results stage, American Joint Committee on Cancer stage and TNM classification, and tumor grade were used to predict cancer specific mortality. Predictive accuracy estimates were compared using the DeLong method for related AUCs. RESULTS: Surveillance, Epidemiology and End Results stage alone (1 predictor variable) was least accurate (74.5%). American Joint Committee on Cancer stage with tumor grade (2 predictor variables) was the most simple and most accurate (80.9%, p <0.001). A benefit similar to that of American Joint Committee on Cancer stage with tumor grade was seen for TNM classification and TG (80.7%, p = 0.8). However, this rule (4 predictor variables) was more complex than American Joint Committee on Cancer stage and tumor grade. CONCLUSIONS: American Joint Committee on Cancer stage combined with tumor grade is the simplest, most accurate cancer specific mortality prediction rule after primary tumor excision for penile squamous cell carcinoma. This method is also more accurate than 2 previous cancer specific mortality prediction rules.

RESUMEN

BACKGROUND: The adherence rate to National Cancer Institute (NCI) recommendations regarding inguinal lymph nodes dissection (ILND) in high grade T1 (G3T1) and T2-4 squamous cell carcinoma of the penis (SCCP) is not known. We assessed ILND rates in a North American cohort. MATERIALS AND METHODS: The 17 registries of the Surveillance, Epidemiology, and End Results (SEER) database included 868 patients with SCCP, diagnosed between 1988 and 2006. Analyses consisted of univariable and multivariable logistic regression models. RESULTS: Overall, 27.6% of patients underwent an ILND. ILND rates were directly proportional with T stage: 19.0%, 30.5%, 30.6%, and 32.6% for, respectively, G3T1, T2, T3, and T4 SCCP (chi-square trend, P = 0.01). ILND rates also increased over time and were 19.3, 27.3, 30.7, and 30.8% for respectively, 1988-1995, 1996-2000, 2001-2003, and 2004-2006 periods (chi-square trend, P = 0.03). Finally, ILND rates decreased with patient age and were 42.6, 33.2, 24.7, and 7.3% for, respectively, patients aged ≤ 57, 58-68, 69-78 and ≥ 79 years of age (chi-square trend, P < 0.001). All 3 variables (T-stage, year of primary tumor excision and patient age) achieved independent predictor status in multivariable analyses. CONCLUSIONS: The overall rate of ILND is low. Nonetheless, there is an upward trend over time. Our data indicate that the adherence to the NCI ILND guidelines is suboptimal. In consequence, ILNDs should be more strongly encouraged.

RESUMEN

PURPOSE: To assess the postsurgical survival of patients with urothelial carcinoma of the bladder with pT0 tumor at pathologic examination of cystectomy specimens. METHODS: A multi-institutional, retrospective database was analyzed with data from 4758 radical cystectomy (RC) patients who underwent RC without neoadjuvant chemotherapy and who were diagnosed with pT0 on the basis of the pathologic specimen. Survival curves were estimated. A multivariate Cox model was used to evaluate the association between prognosis factors and disease recurrence or survival. RESULTS: Overall, 258 patients (5.4%) were included in the study. The median age was 64 years. At last resection, 171 tumors were invasive (at least pT2), and 87 were not. Median follow-up was 51 months. At multivariate analysis, initial location of the tumor and absence of lymphadenectomy were associated with tumor recurrence (P = 0.03 and P = 0.005, respectively) and specific mortality (P = 0.005 and 0.001, respectively). The main limitation of the study is its retrospective design, which is due to the rarity of this situation. Cancer-specific and recurrence-free survival rates were 89 and 85%, respectively, at 5 years and 82 and 80%, respectively, at 10 years. CONCLUSIONS: Despite acceptable oncological outcomes, patients with a pT0 tumor at the time of RC are still at risk of recurrence and progression and should not be considered to be entirely cured. In this population, stringent follow-up according to current recommendations should be effective.

RESUMEN

BACKGROUND: Renal insufficiency can occur in patients with congenital lower urinary tract malformations (LUTM) even when managed during infancy. Data in the current literature concerning this subject remain sparse. The aim of this study was to report the feasibility and long-term results of renal transplantation during adulthood in patients with a congenital LUTM. METHODS: A retrospective multicenter study from 3 French renal transplant centers was conducted, including 123 transplantations on 112 patients with LUTM (1996-2016). Graft survival, patient survival, and complications were analyzed. Results were stratified according to the underlying uropathy and the type of initial management during childhood or before transplantation. RESULTS: In this study, patients suffering from posterior urethral valves (n = 49), spina bifida (n = 21), central neurogenic bladder (n = 13), bladder exstrophy (n = 14), prune belly syndrome (n = 12), Hinman syndrome (n = 6), urogenital sinus (n = 4), and other pathologies (n = 4) were included. The mean age at transplantation was 32.1 years old (±11.2). The mean follow-up period was 7.2 years. Patient survival at 1, 5, 10, and 15 years was 97.4%, 93.0%, 89.4%, and 80.0%, respectively. Graft survival at 1, 5, 10, 15, and 20 years was 96.6%, 87.6%, 77.3%, 60.6%, and 36.4%, respectively. Enterocystoplasty and continent urinary diversions exposed grafts to more frequent acute pyelonephritis (P = 0.02). There was no difference in graft survival when transplantation was performed on an enterocystoplasty or urinary diversions compared with a native bladder, provided a well-conducted bladder management. CONCLUSIONS: Even though enterocystoplasty and continent urinary diversions exposed grafts to more frequent acute graft pyelonephritis, patient and graft survival rates in LUTM at 10 years were similar to other kidney transplantations on native bladders.

RESUMEN

PURPOSE: The objective of this study was to compare living-donor kidney transplantation (LDKT) performed either sequentially, in one operating room, leading to extended cold ischemia time (CIT) or simultaneously, in two different operating room, with shorter CIT. METHODS: We retrospectively included all living-donor nephrectomies and kidney transplantations, performed from March 2010 to March 2014, in three French university centers. In the first one (C1), LDKTs were performed in sequential manner (Sequential group) and in C2 and C3, LDKTs were performed in simultaneous manner (Simultaneous group). RESULTS: A total of 324 LDKT were performed: 176 LDKT in Sequential group and 148 LDKT in Simultaneous group. Patients characteristics were equivalent between groups, except nephrectomy side, ABO mismatch rate and previous kidney transplantation rate. CIT, rewarming time, transfusion and delayed graft function (DGF) were significantly higher in Sequential group. Overall survival and graft survival of kidney transplant recipients were similar in the Sequential and Simultaneous groups. 5-year eGFR was similar between groups. In univariate analysis, number of graft arteries, recipient BMI, previous kidney transplantation status and CIT were significant predictors of DGF. Only previous kidney transplantation status was an independent predictive factor of DGF in the multivariate analysis. CONCLUSIONS: Sequential surgical organization results in the same functional results as simultaneous surgical organization. DGF was higher for LDKT performed sequentially but at 5-year overall survival, graft survival and eGFR were similar between these two types of transplant organizations.

RESUMEN

Peroxisome proliferator-activated receptor gamma (PPARgamma) might not be permissive to ligand activation in prostate cancer cells. Association of PPARgamma with repressing factors or posttranslational modifications in PPARgamma protein could explain the lack of effect of PPARgamma ligands in a recent randomized clinical trial. Using cells and prostate cancer xenograft mouse models, we demonstrate in this study that a combination treatment using the PPARgamma agonist pioglitazone and the histone deacetylase inhibitor valproic acid is more efficient at inhibiting prostate tumor growth than each individual therapy. We show that the combination treatment impairs the bone-invasive potential of prostate cancer cells in mice. In addition, we demonstrate that expression of E-cadherin, a protein involved in the control of cell migration and invasion, is highly up-regulated in the presence of valproic acid and pioglitazone. We show that E-cadherin expression responds only to the combination treatment and not to single PPARgamma agonists, defining a new class of PPARgamma target genes. These results open up new therapeutic perspectives in the treatment of prostate cancer.

RESUMEN

BACKGROUND: We conducted a retrospective multi-centre study to determine the characteristics of prostate cancer in renal transplant recipients (RTR) and to analyse the relation with immunosuppressive maintenance therapies. METHODS: Patients from 19 French transplant centres diagnosed with prostate cancer at least 1 year after kidney transplantation were included in this study. Data regarding demographics, kidney transplantation, prostate cancer and immunosuppressive treatment were analysed. RESULTS: Sixty-two patients met the eligibility criteria for this study. Thirty-eight patients (61.3%) received calcineurin inhibitors (CNI) and azathioprine (AZA) with or without steroids, twenty received CNI with or without steroids (32.2%) and four received CNI and mycophenolate mofetil (6.5%). Patients with CNI and AZA immunosuppressive therapy presented more high-stage cancer (T3 and T4) when compared to patients receiving CNI alone (47.5% versus 15%, respectively, P = 0.03). A non-significant increase in lymph node invasion was found in patients receiving CNI and AZA compared to patients receiving CNI alone (21% versus 5%, P = 0.16). In the multivariate analysis, the immunosuppressive regimen with CNI and AZA was the only independent risk factor for locally advanced disease (P = 0.007). CONCLUSION: Our results showed that RTR are at risk for early occurrence and for locally advanced prostate cancer, especially when they received a CNI and AZA maintenance immunosuppressive therapy.

RESUMEN

OBJECTIVE: To evaluate the morbidity of living donor kidney harvesting and the long-term medical consequences and impact on quality of life (QoL). MATERIAL AND METHODS: Retrospective analysis of medical and surgical data for 114 living kidney donors in a single teaching hospital between 1977 and 2005. Complications were evaluated in relation to the surgical approach and body mass index (BMI) using a Chi-square test or Fisher's exact test. Changes in renal function (serum creatinine, creatinine clearance), proteinuria and blood pressure (BP) were studied by Student's t test or a Mann-Whitney U or Wilcoxon nonparametric test. Long-term QoL was evaluated by the MOS SF-36 questionnaire and a local questionnaire and was then compared to that of the French general population. RESULTS: The median follow-up was 63 months. The morbidity of kidney harvesting was significantly correlated with the surgical approach (p = 0.018) and a BMI > or = 25 kg/m2 (p = 0.014). No mortality was observed in this series. A moderate elevation of serum creatinine was observed during follow-up (mean serum creatinine increased from 82.2 micromol/l [+/- 16.3] to 104.5 micromol/l [+/- 19.9]), and mean creatinine clearance decreased from 113.4 ml/min [+/- 27.6] to 76 ml/min [+/- 29.9]. Little impact was observed on proteinuria and BP and QoL was not altered by kidney harvesting. CONCLUSION: The perioperative complication rate is correlated with BMI and a flank incision. Kidney harvesting lowers glomerular filtration, but clearance remained stable during follow-up. Macroalbuminuria or hypertension may be observed, but their frequency is not higher than in the general population. The QoL of living donors is not altered.

RESUMEN

Chronic inflammation may play a role in prostate cancer carcinogenesis. In that context, our objective was to investigate the role of nonsteroidal anti-inflammatory drugs (NSAIDs) in prostate cancer risk based on the EPICAP data. EPICAP is a population-based case-control study carried out in 2012-2013 (département of Hérault, France) that enrolled 819 men aged less than 75 years old newly diagnosed for prostate cancer and 879 controls frequency matched to the cases on age. Face to face interviews gathered information on several potential risk factors including NSAIDs use. Odds ratios (ORs) and their 95% confidence intervals (CIs) were calculated using unconditional logistic regression models. All-NSAIDs use was inversely associated with prostate cancer: OR 0.77, 95% CI 0.61-0.98, especially in men using NSAIDs that preferentially inhibit COX-2 activity (OR 0.48, 95% CI 0.28-0.79). Nonaspirin NSAIDs users had a decreased risk of prostate cancer (OR 0.72, 95% CI 0.53-0.99), particularly among men with an aggressive prostate cancer (OR 0.49, 95% CI 0.27-0.89) and in men with a personal history of prostatitis (OR 0.21, 95% CI 0.07-0.59). Our results are in favor of a decreased risk of prostate cancer in men using NSAIDs, particularly for men using preferential anti-COX-2 activity. The protective effect of NSAIDs seems to be more pronounced in aggressive prostate cancer and in men with a personal history of prostatitis, but this needs further investigations to be confirmed.

RESUMEN

UNLABELLED: Chemotherapy occupies an increasingly important place in the management of hormone-resistant metastatic prostate cancer. For the first time in this disease, docetaxel increases the survival of patients, with a modest, but definite median gain of about 2 months. In everyday practice, the indication for second-line chemotherapy after immediate or delayed failure of first-line chemotherapy is sometimes considered, although objective data concerning its efficacy are limited. The objective of the present study was to retrospectively evaluate the results obtained with second-line chemotherapy in a patient cohort managed at the Montpellier Regional Cancer Centre. PATIENTS AND METHODS: Clinical characteristics, treatments delivered and outcome of 43 patients who received two successive lines of chemotherapy were retrospectively collected by means of a standardized questionnaire. Three groups of patients were defined as a function of the chemotherapy protocols delivered: docetaxel alone or in combination, mitoxantrone and other protocols not comprising either docetaxel or mitoxantrone. Responses to chemotherapy were analysed according to three criteria: objective responses, laboratory responses and palliative responses. RESULTS: At the time of second-line chemotherapy, the median age of the patients was 69 years (range: 46 to 83). The median interval between the end of first-line chemotherapy and the start of second-line chemotherapy was 3 months (range: 1 to 15). The protocols administered comprised docetaxel alone (12 patients) or in combination with cisplatin (4 patients), mitoxantrone in 13 patients, or other cytotoxic molecules such as vinblastine, doxorubicin or etoposide in combination with a platinum salt (14 patients). The median number of cycles delivered was 4 (range: 1 to 10). No objective response was observed. Six (14%) patients obtained a laboratory response. A palliative response was observed in 16 (37%) patients, 7 of whom were treated with a docetaxel-based protocol, 6 were treated with mitoxantrone and 3 were treated by other protocols. The median duration of palliative response was 3 months (range: 1 to 6). The median survival was 8 months (range: 1 to 24), with no significant difference between the various protocols. CONCLUSION: In 2006, the objective of second-line chemotherapy in patients with hormone-resistant prostate cancer appears to be purely palliative. No reference protocol has been defined among currently available cytotoxic molecules. The indication must therefore take into account the benefit/risk balance to avoid compromising the patients quality of life. Therapeutic trials are essential to develop effective new molecules.

RESUMEN

INTRODUCTION: An increasing number of patients with prostate cancer (PC) are diagnosed and treated. The aim of this study was to investigate urinary incontinence (UI) and sexual dysfunction (SD) two years after treatment for localized prostate cancer (PC). METHODS: This study followed all cases of localized PC diagnosed between 2008 and 2009 in men aged≤65years old and still alive two years after treatment. In total, 437 men were recruited. Data were collected using a standardized questionnaire and by cross-checking with data from the cancer registry. Descriptive and comparative analyses were performed to evaluate persisting UI and SD at 2years. RESULTS: At two years after treatment, UI was persistent in 48.8%; 41.2% had used urinary protections, and 39.2% had used at least 1 pad/day; 55.2% reported financial difficulties for purchasing protective pads. In total, 22.7% did not consult a specialist for UI. SD was persistent in 82.8%; 30.4% did not consult a specialist for SD. SD had a negative impact on the sex life of patients and their partners. After adjustment for cancer stage, prostatectomy was significantly associated with persisting UI and SD at two years. CONCLUSION: Two years after treatment, rates of persisting UI and/or SD remain high. Treatment by prostatectomy was significantly associated with an increased risk of persisting adverse effects at two years. The different toxicities between treatments should be presented to patients before initiating therapy in order to encourage the patient to contributed to shared treatment decision-making.

RESUMEN

Intratubular neoplasia (ITN) of the testis is a precursor of germ cell tumour, apart from spermatocytic seminoma. It is often detected in testicular tissue adjacent to germ cell tumours, but is less common in the contralateral testis. Early diagnosis of ITN by testicular biopsy would allow earlier, conservative management. However, this approach remains highly controversial except in very specific indications.

RESUMEN

BACKGROUND: Despite the fact that new drugs have emerged from clinical research in urothelial cancer during the last decade, the prognosis of patients with advanced disease remains poor with a median survival of 12 to 14 months. We designed a feasibility study of gemcitabine and oxaliplatin (GO) in patients with advanced urothelial cancer. PATIENTS AND METHODS: Twenty patients received bimonthly cycles of gemcitabine 1500 mg/m2 and oxaliplatin 85 mg/m2. The cycles were given at 2-week intervals without G-CSF support. Thirteen patients were treated with the GO combination as first-line chemotherapy because of a poor performance status or a creatinine clearance < 1 ml/s. RESULTS: The median number of cycles of GO was 5 (1-7). The median number of days between cycles was 14 throughout the treatment. Seven (8%) out of 87 cycles had to be delayed because of neutropenia or asthenia. A 25% dose reduction in the doses of cytotoxic drugs was necessary in 2 patients. Chemotherapy was stopped before the sixth cycle because of an early death related to a myocardial infarction in 1 patient, a grade 3 neuropathy in 1 patient and a progressive disease in 9 patients. CONCLUSION: Using these doses and schedules, the GO regimen appears a safe therapy for patients with advanced urothelial cancer. Phase II studies are required to assess the possible role of this combination in advanced urothelial cancer.
