Adherence to the World Cancer Research Fund/American Institute for Cancer Research recommendations for cancer prevention in adolescent and young adult (AYA) cancer survivors: results from the SURVAYA study.

PURPOSE: For adolescent and young adult (AYA) cancer survivors with a good prognosis, having a healthy lifestyle prevents morbidity and mortality after treatment. The aim of this study was to investigate the prevalence of (un)healthy lifestyle behaviors and related determinants in AYA cancer survivors. METHODS: A population-based, cross-sectional study was performed among long-term (5-20 years) AYA cancer survivors (18-39 years old at diagnosis) registered within the Netherlands Cancer Registry. Self-reported questionnaires data about health behaviors were used to calculate the 2018 World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) adherence score. Associations between the score and clinical/sociodemographic determinants of (un)healthy behaviors were investigated using logistic regression models. RESULTS: The mean WCRF/AICR score was low to moderate, 3.8 ± 1.2 (0.5-7.0) (n = 3668). Sixty-one percent adhered to "limit the consumption of sugar sweetened drinks," 28% to "be a healthy weight," 25% to "fruit and vegetable consumption," and 31% to "limit alcohol consumption." Moderate and high adherence were associated with being a woman (ORmoderate = 1.46, 95% CI = 1.14-1.85, and ORhigh = 1.87, 95% CI = 1.46-2.4) and highly educated (ORmoderate = 1.54, 95% CI = 1.30-1.83, and ORhigh = 1.87, 95% CI = 1.46-2.4). Low adherence was associated with smoking (ORmoderate = 0.68, 95% CI = 0.50-0.92, and ORhigh = 0.30, 95% CI = 0.21-0.44) and diagnosis of germ cell tumor (ORmoderate = 0.58, 95% CI = 0.39-0.86, and ORhigh = 0.45, 95% CI = 0.30-0.69). CONCLUSIONS: Adherence to the 2018 WCRF/AICR lifestyle recommendations was low to moderate, especially regarding body weight, fruit, vegetables, and alcohol consumption. Men, current smokers, lower-educated participants, and/or those diagnosed with germ cell tumors were less likely to have a healthy lifestyle. IMPLICATIONS FOR CANCER SURVIVORS: Health-promotion programs (e.g., age-specific tools) are needed, focusing on high-risk groups.

Prevalence of neoplasia at colonoscopy among testicular cancer survivors treated with platinum-based chemotherapy.

Testicular cancer survivors (TCS) treated with platinum-based chemotherapy have an increased risk of colorectal cancer (CRC). We determined the yield of colonoscopy in TCS to assess its potential in reducing CRC incidence and mortality. We conducted a colonoscopy screening study among TCS in four Dutch hospitals to assess the yield of colorectal neoplasia. Neoplasia was defined as adenomas, serrated polyps (SPs), advanced adenomas (AAs: ≥10 mm diameter, high-grade dysplasia or ≥25% villous component), advanced serrated polyps (ASPs: ≥10 mm diameter or dysplasia) or CRC. Advanced neoplasia (AN) was defined as AA, ASP or CRC. Colonoscopy yield was compared to average-risk American males who underwent screening colonoscopy (n = 24,193) using a propensity score matched analysis, adjusted for age, smoking status, alcohol consumption and body mass index. A total of 137 TCS underwent colonoscopy. Median age was 50 years among TCS (IQR 43-57) vs 55 years (IQR 51-62) among American controls. A total of 126 TCS were matched to 602 controls. The prevalence of AN was higher in TCS than in controls (8.7% vs 1.7%; P = .0002). Nonadvanced adenomas and SPs were detected in 45.2% of TCS vs 5.5% of controls (P < .0001). No lesions were detected in 46.0% of TCS vs 92.9% of controls (P < .0001). TCS treated with platinum-based chemotherapy have a higher prevalence of neoplasia and AN than matched controls. These results support our hypothesis that platinum-based chemotherapy increases the risk of colorectal neoplasia in TCS. Cost-effectiveness studies are warranted to ascertain the threshold of AN prevalence that justifies the recommendation of colonoscopy for TCS.

Health-related quality of life of Adolescent and Young Adult Cancer Survivors before and during the COVID-19 pandemic: longitudinal improvements on social functioning and fatigue.

The health-related quality of life (HRQoL) among long-term Adolescent and Young Adult Cancer Survivors (AYACS) and an age- and sex-matched normative population was examined. Although the HRQoL of AYACS was worse compared to the normative population before and during the COVID-19 pandemic, the scores of AYACS improved over time in contrast to the normative population. Presumably, AYACS are used to adjusting their lives to stressful life events. Furthermore, the lockdown may have been beneficial for AYACS who face difficulties fully participating in society due to the impact of cancer. AYACS who encounter HRQoL issues could benefit from support interventions to empower them and build resilience.

Cardiovascular Disease in Testicular Cancer Survivors: Identification of Risk Factors and Impact on Quality of Life.

PURPOSE: Testicular cancer (TC) treatment is clearly associated with cardiovascular morbidity and mortality. To enable development of preventive strategies for cardiovascular disease (CVD), we assessed cardiometabolic risk factors and quality of life (QoL) in TC survivors. METHODS: Incidence of coronary artery disease, myocardial infarction, and heart failure after TC treatment was assessed in a multicenter cohort comprising 4,748 patients treated at the age of 12-50 years between 1976 and 2007. Patients who had developed CVD and a random sample from the cohort (subcohort) received a questionnaire on cardiometabolic risk factors and QoL. A subgroup of responders in the subcohort additionally underwent clinical evaluation of cardiovascular risk factors. RESULTS: After a median follow-up of 16 years, 272 patients had developed CVD. Compared with orchidectomy only, cisplatin combination chemotherapy was associated with an increased CVD risk (hazard ratio [HR], 1.9; 95% CI, 1.1 to 3.1). Patients who were obese or a smoker at diagnosis (HR, 4.6; 95% CI, 2.0 to 10.0 and HR, 1.7; 95% CI, 1.1 to 2.4, respectively), developed Raynaud's phenomenon (HR, 1.9; 95% CI, 1.1 to 3.6) or dyslipidemia (HR, 2.8; 95% CI, 1.6 to 4.7) or had a positive family history for CVD (HR, 2.9; 95% CI, 1.7 to 4.9) had higher CVD risk. More TC survivors with CVD reported inferior QoL on physical domains than survivors who did not develop CVD. Of 304 TC survivors who underwent clinical evaluation for cardiovascular risk factors (median age at assessment: 51 years), 86% had dyslipidemia, 50% had hypertension, and 35% had metabolic syndrome, irrespective of treatment. CONCLUSION: Cardiovascular events in TC survivors impair QoL. Many TC survivors have undetected cardiovascular risk factors. We advocate early lifestyle adjustments and lifelong follow-up with low-threshold treatment of cardiovascular risk factors, especially in obese and smoking patients treated with platinum-based chemotherapy.

Clinical outcome of robot-assisted residual mass resection in metastatic nonseminomatous germ cell tumor.

PURPOSE: To evaluate the outcome of robot-assisted residual mass resection (RA-RMR) in nonseminomatous germ cell tumor (NSGCT) patients with residual tumor following chemotherapy. PATIENTS AND METHODS: Retrospective medical chart analysis of all patients with NSGCT undergoing RA-RMR at two tertiary referral centers between January 2007 and April 2019. Patients were considered for RA-RMR in case of a residual tumor between 10 and 50 mm at cross-sectional computed tomography (CT) imaging located ventrally or laterally from the aorta or vena cava, with normalized tumor markers following completion of chemotherapy, and no history of retroperitoneal surgery. RESULTS: A total of 45 patients were included in the analysis. The Royal Marsden stage before chemotherapy was IIA in 13 (28.9%), IIB in 16 (35.6%), IIC in 3 (6.7%) and IV in 13 patients (28.9%). The median residual tumor size was 1.9 cm (interquartile range [IQR] 1.4-2.8; range 1.0-5.0). Five procedures (11.1%) were converted to an open procedure due to a vascular injury (n = 2), technical difficulty (n = 2) or tumor debris leakage (n = 1). A postoperative adverse event occurred in two patients (4.4%). Histopathology showed teratoma, necrosis and viable cancer in 29 (64.4%), 14 (31.1%), and two patients (4.4%), respectively. After a median follow-up of 41 months (IQR 22-70), one patient (2.2%) relapsed in the retroperitoneum. The one- and 2-year recurrence-free survival rate was 98%. CONCLUSION: RA-RMR is an appropriate treatment option in selected patients, potentially providing excellent cure rates with minimal morbidity. Long-term outcome data are needed to further support this strategy and determine inclusion and exclusion criteria.

Proteomic markers with prognostic impact on outcome of chronic lymphocytic leukemia patients under chemo-immunotherapy: results from the HOVON 109 study.

Despite recent identification of several prognostic markers, there is still a need for new prognostic parameters able to predict clinical outcome in chronic lymphocytic leukemia (CLL) patients. Here, we aimed to validate the prognostic ability of known (proteomic) markers measured pretreatment and to search for new proteomic markers that might be related to treatment response in CLL. To this end, baseline serum samples of 51 CLL patients treated with chemo-immunotherapy were analyzed for 360 proteomic markers, using Olink technology. Median event-free survival (EFS) was 23 months (range: 1.25-60.9). Patients with high levels of sCD23 (>11.27, p = 0.026), sCD27 (>11.03, p = 0.04), SPINT1 (>1.6, p = 0.001), and LY9 (>8.22, p = 0.0003) had a shorter EFS than those with marker levels below the median. The effect of sCD23 on EFS differed between immunoglobulin heavy chain variable gene-mutated and unmutated patients, with the shortest EFS for unmutated CLL patients with sCD23 levels above the median. Taken together, our results validate the prognostic impact of sCD23 and highlight SPINT1 and LY9 as possible promising markers for treatment response in CLL patients.

A testosterone-producing Leydig cell tumor metastasis during hormonal treatment of prostate cancer.

We describe a patient with a testosterone-producing metastasis discovered during the follow-up of prostate cancer. The patient had a history of a Leydig cell tumor (LCT) in the right testicle for which he underwent radical orchiectomy at the age of 60 years. Within a year after orchiectomy, he was diagnosed with prostate cancer. He received a radical prostatectomy with pelvic lymph node dissection. Due to recurrent prostate cancer, he underwent salvage radiation to the prostatic fossa and pelvic lymph node stations with hormonal treatment for 3 years. After approximately 1.5 years of chemical castration, a significant increase in testosterone level occurred. Further, diagnostic evaluations and surgery revealed a testosterone-producing LCT metastasis in the retroperitoneum.

Survival and Cost-Effectiveness of Trabectedin Compared to Ifosfamide Monotherapy in Advanced Soft Tissue Sarcoma Patients.

Trabectedin and ifosfamide are among the few cytostatic agents active in advanced soft tissue sarcomas (STSs). Trabectedin is most potent against so-called L-sarcomas (leiomyosarcoma and liposarcoma). The survival gain and cost-effectiveness of these agents in a second-line setting were analysed in the setting of advanced STS after failure of anthracyclines. A prospective observational trial had previously been performed to assess the use of trabectedin in a Dutch real-world setting. Data on ifosfamide monotherapy were acquired from previous studies, and an indirect comparison of survival was made. A state-transition economic model was constructed, in which patients could be in mutually exclusive states of being preprogression, postprogression, or deceased. The costs and quality-adjusted life years (QALYs) for both treatments were assessed from a Dutch health-care perspective. Separate analyses for the group of L-sarcomas and non-L-sarcomas were performed. Trabectedin treatment resulted in a median progression-free survival of 5.2 months for L-sarcoma patients, 2.0 months for non-L-sarcoma patients, and a median overall survival of 11.8 and 6.0 months, respectively. For L-sarcoma patients, trabectedin offered an increase of 0.368 life years and 0.251 QALYs compared to ifosfamide and €20,082 in additional costs, for an incremental cost-effectiveness ratio (ICER) of €80,000 per QALY gained. In the non-L-sarcoma patients, trabectedin resulted in 0.413 less life years and 0.266 less QALYs, at the increased cost of €4,698. The difference in survival between drugs and the acquisition costs of trabectedin were the main influences in these models. Trabectedin was shown to have antitumour efficacy in advanced L-sarcoma. From a health economics perspective, the costs per QALY gained compared to ifosfamide monotherapy that may be acceptable, considering what is currently regarded as acceptable in the Netherlands.

Feasibility and efficacy of addition of individualized-dose lenalidomide to chlorambucil and rituximab as first-line treatment in elderly and FCR-unfit patients with advanced chronic lymphocytic leukemia.

Lenalidomide has been proven to be effective but with a distinct and difficult to manage toxicity profile in the context of chronic lymphocytic leukemia, potentially hampering combination treatment with this drug. We conducted a phase 1-2 study to evaluate the efficacy and safety of six cycles of chlorambucil (7 mg/m2 daily), rituximab (375 mg/m2 cycle 1 and 500 mg/m2 cycles 2-6) and individually-dosed lenalidomide (escalated from 2.5 mg to 10 mg) (induction-I) in first-line treatment of patients with chronic lymphocytic leukemia unfit for treatment with fludarabine, cyclophosphamide and rituximab. This was followed by 6 months of 10 mg lenalidomide monotherapy (induction-II). Of 53 evaluable patients in phase 2 of the study, 47 (89%) completed induction-I and 36 (68%) completed induction-II. In an intention-to-treat analysis, the overall response rate was 83%. The median progression-free survival was 49 months, after a median follow-up time of 27 months. The 2- and 3-year progression-free survival rates were 58% and 54%, respectively. The corresponding rates for overall survival were 98% and 95%. No tumor lysis syndrome was observed, while tumor flair reaction occurred in five patients (9%, 1 grade 3). The most common hematologic toxicity was grade 3-4 neutropenia, which occurred in 73% of the patients. In conclusion, addition of lenalidomide to a chemotherapy backbone followed by a fixed duration of lenalidomide monotherapy resulted in high remission rates and progression-free survival rates, which seem comparable to those observed with novel drug combinations including novel CD20 monoclonal antibodies or kinase inhibitors. Although lenalidomide-specific toxicity remains a concern, an individualized dose-escalation schedule is feasible and results in an acceptable toxicity profile. EuraCT number: 2010-022294-34.

Concurrent Radiotherapy and Panitumumab after Lymph Node Dissection and Induction Chemotherapy for Invasive Bladder Cancer.

PURPOSE: In this prospective study we evaluated the safety and efficacy of concurrent radiotherapy and panitumumab following neoadjuvant/induction chemotherapy and pelvic lymph node dissection as a bladder preserving therapy for invasive bladder cancer. MATERIALS AND METHODS: Patients with cT1-4N0-2M0 bladder cancer were treated with pelvic lymph node dissection and 4 cycles of platinum based induction chemotherapy followed by a 6½-week schedule of weekly panitumumab (2.5 mg/kg) and concurrent radiotherapy to the bladder (33 × 2 Gy). As the primary objective we compared concurrent radiotherapy and panitumumab toxicity to a historical control toxicity rate of concurrent cisplatin/radiotherapy (less than 35% of patients with Grade 3-5 toxicity). A sample size of 31 patients was estimated. Secondary end points included complete remission at 3-month followup, the bladder preservation rate, EGFR (epidermal growth factor receptor) expression and RAS mutational status. RESULTS: Of the 38 cases initially included in this study 34 were staged cN0. After pelvic lymph node dissection 7 cases (21%) were up staged to pN+. Of the 38 patients 31 started concurrent radiotherapy and panitumumab. During concurrent radiotherapy and panitumumab 5 patients (16%, 95% CI 0-31) experienced systemic or local grade 3-4 toxicity. Four patients did not complete treatment due to adverse events. Complete remission was achieved in 29 of 31 patients (94%, 95% CI 83-100). At a median followup of 34 months 4 patients had local recurrence, for which 3 (10%) underwent salvage cystectomy. Two tumors showed EGFR or RAS mutation while 84% showed positive EGFR expression. CONCLUSIONS: Concurrent radiotherapy and panitumumab following induction chemotherapy and pelvic lymph node dissection has a safety profile that is noninferior to the historical profile of concurrent cisplatin/radiotherapy. The high complete remission and bladder preservation rates are promising and warrant further study.

Sentinel node biopsy in clinical stage I testicular cancer enables early detection of occult metastatic disease.

OBJECTIVES: To report the long-term results of the sentinel node (SN) approach in patients with clinical stage I testicular tumours in our facility. PATIENTS AND METHODS: We conducted an analysis of 27 consecutive patients suspected of clinical stage I testicular germ cell tumour (TGCT) and treated with an SN procedure at our tertiary referral centre. SNs were identified using lymphoscintigraphy with or without single-photo-emission computed tomography with CT (SPECT/CT). Patients underwent laparoscopic retroperitoneal SN excision with inguinal orchiectomy. Patients with a tumour-positive SN underwent adjuvant treatment. Follow-up was conducted according to then-current guidelines. RESULTS: In two patients, no SNs were visualized on scintigraphy. In the remaining 25 patients, a median (range) of 3 (1-4) SNs per patient were removed. Two patients showed no malignancy on histopathological examination of the testis. Of the 23 patients diagnosed with TGCT (16 seminomas, seven non-seminomas), three (13.0%) had occult metastatic disease. All 23 patients were without evidence of disease at a median (range) follow-up of 63.9 (29.0-143.4) months. CONCLUSION: The SN procedure allows early identification of patients with occult metastatic disease in clinical stage I TGCT, enabling early treatment.

Risk of diabetes after para-aortic radiation for testicular cancer.

BACKGROUND: While the risk of diabetes is increased following radiation exposure to the pancreas among childhood cancer survivors, its association among testicular cancer (TC) survivors has not been investigated. METHODS: Diabetes risk was studied in 2998 1-year TC survivors treated before 50 years of age with orchidectomy with/without radiotherapy between 1976 and 2007. Diabetes incidence was compared with general population rates. Treatment-specific risk of diabetes was assessed using a case-cohort design. RESULTS: With a median follow-up of 13.4 years, 161 TC survivors were diagnosed with diabetes. Diabetes risk was not increased compared to general population rates (standardised incidence ratios (SIR): 0.9; 95% confidence interval (95% CI): 0.7-1.1). Adjusted for age, para-aortic radiotherapy was associated with a 1.66-fold (95% CI: 1.05-2.62) increased diabetes risk compared to no radiotherapy. The excess hazard increased with 0.31 with every 10 Gy increase in the prescribed radiation dose (95% CI: 0.11-0.51, P = 0.003, adjusted for age and BMI); restricted to irradiated patients the excess hazard increased with 0.33 (95% CI: -0.14 to 0.81, P = 0.169) with every 10 Gy increase in radiation dose. CONCLUSION: Compared to surgery only, para-aortic irradiation is associated with increased diabetes risk among TC survivors.

Brain Hyperconnectivity >10 Years After Cisplatin-Based Chemotherapy for Testicular Cancer.

Chemotherapy for testicular cancer (TC) has been associated with neurotoxic effects shortly post-treatment. Late effects of chemotherapy on brain function in this patient group are still unknown. In this study, we investigated differences between patients with and without chemotherapy in functional brain networks at rest and during an affective processing functional magnetic resonance imaging (fMRI) task on average >14 years post-treatment. In addition, we report on changes in cognitive functioning during survivorship by comparing present and previous performance on a neuropsychological test battery on average 11 years earlier (3 years post-treatment). Twenty-eight chemotherapy (43.1 ± 7.5 years) and 23 surgery-only (48.2 ± 9.5 years) TC survivors were examined using neurocognitive tests and 3T-fMRI >10 years after treatment end. Brain functional networks were identified using dual regression independent component analysis. Task fMRI was analyzed using a block design. Standardized domain change scores were calculated for each individual to assess cognitive change. TC patients in the chemotherapy group showed functional hyperconnectivity at rest in the precuneus network, sensory and motor function network, executive control network, and the ventral stream network when compared with surgery-only patients. Furthermore, hypoactivation was found when performing the affective processing task. Cognitive data revealed that both groups showed comparable patterns of change from 3 to 14 years after initial treatment. This study provides novel insights on the possible underlying neurobiological mechanisms of late neurotoxic effects of cisplatin-based chemotherapy. Present findings reveal that functional hyperconnectivity is widespread, possibly to compensate for the pathophysiological disturbances. This concurs with our previous findings of structural hyperconnectivity in white matter. Longitudinal multimodal imaging studies are warranted to further investigate the association between long-term structural and functional network connectivity data, as well as its relationship with cognitive changes.

Neoadjuvant induction dose-dense MVAC for muscle invasive bladder cancer: efficacy and safety compared with classic MVAC and gemcitabine/cisplatin.

PURPOSE: To investigate the efficacy and safety of neoadjuvant induction dose-dense MVAC (dd-MVAC) for muscle invasive bladder cancer (MIBC). Results of the 2-week-per-cycle regimen were compared with classic MVAC (4 weeks per cycle) and gemcitabine/cisplatin (GC, 3 weeks per cycle). METHODS: We included 166 patients with non-organ-confined MIBC, who received neoadjuvant induction dd-MVAC (80), classic MVAC (35), or GC (51) between 1990 and 2014. Complete pathological response (pCR) was defined as no evidence of residual tumor in cystectomy and lymphadenectomy specimens (ypT0N0). pCR and toxicity rates were compared among regimens. RESULTS: pCR was found in 29% of dd-MVAC-treated patients, which was not significantly different from classic MVAC (20%, p = 0.366) and GC (32%, p = 0.845). Grade 3-4 toxicity rates related to dd-MVAC and GC (44%) were similar (p = 0.202), whereas the toxicity rate for classic MVAC (55%) was significantly higher than for dd-MVAC (32%) uncorrected (p = 0.026) and corrected for patient and tumor characteristics (OR 2.84, p = 0.037). CONCLUSIONS: Neoadjuvant induction dd-MVAC resulted in pathological response rates similar to classic MVAC and GC treatment in patients with non-organ-confined MIBC. The shorter cycle duration compared with classic MVAC and GC and the significantly lower toxicity rate compared with classic MVAC indicate that dd-MVAC should be the preferred option for neoadjuvant induction treatment.

A phase I study on the combination of neoadjuvant radiotherapy plus pazopanib in patients with locally advanced soft tissue sarcoma of the extremities.

UNLABELLED: Accumulating evidence suggests significant synergism combining radiotherapy (RT) with angiogenesis targeted therapies. This multicenter prospective phase I clinical trial established the safety profile and recommended dose for further studies of pazopanib concurrent with preoperative RT in patients with extremity soft tissue sarcomas (ESTS) in curative setting. METHODS: Patients with deep seated intermediate and high grade sarcomas, ≥ 5 cm, received once daily pazopanib (dose-escalation cohorts 400 mg, 600 mg and 800 mg) for 6 weeks and 50 Gy preoperative RT starting Day 8. Surgery was performed 5-7 weeks later. Toxicity was scored according to CTC criteria 4.0. Dose limiting toxicities (DLT) were divided into two separate sets; DLT-I being toxicities occurring during the 6-week chemoradiotherapy period within the radiation portals until day of surgery (designated as DLT-I) and those occurring perioperatively until Day 21 after surgery (DLT-II). RESULTS: A total of 12 patients were enrolled, 11 were evaluable (3 females and 8 males, median age 58 years, range 24-78 years, median tumor size 9 cm, range 5-15 cm). Ten underwent surgery. No increased toxicity inside the radiation fields was seen, but two of 10 patients (one each in the 400 mg and 600 mg cohorts) showed delayed wound healing after surgery. None of the patients showed significant volume reductions after RT. Evaluation of the resection specimen showed pathological (near) complete responses (≥ 95% necrosis rate) in four of 10 cases. Unexpectedly, grade 3 + hepatotoxicity led to premature pazopanib interruption in three of 11 (27%) of cases. CONCLUSION: Apart from hepatotoxicity, neoadjuvant pazopanib 800 mg daily in combination with 50 Gy seems tolerable; the regimen appears to demonstrate promising activity in ESTS and is the recommended dose for further studies.

Imatinib-induced agranulocytosis in patients with gastrointestinal stromal tumors.

Agranulocytosis is a rare but serious side effect of imatinib in gastrointestinal stromal tumor (GIST) patients. Imatinib is an inhibitor of the proto-oncogene tyrosine kinase (c-kit) and the first-line agent in patients with locally advanced and metastatic GIST. Little evidence is available on the management of this adverse event, and consensus-based guidelines are lacking. In this article, we describe 4 patients with agranulocytosis after starting imatinib. In addition, an overview of the available literature concerning the underlying mechanisms is given, and therapeutic strategies for overcoming this adverse event are discussed. In our experience it appears safe to restart imatinib after normalization of neutrophil count. In case of relapse of agranulocytosis, reintroduction combined with prednisolone, with treatment with granulocyte colony-stimulating factor or dose reduction can be considered.

Immediate versus deferred chemotherapy after radical cystectomy in patients with pT3-pT4 or N+ M0 urothelial carcinoma of the bladder (EORTC 30994): an intergroup, open-label, randomised phase 3 trial.

BACKGROUND: Patients with muscle-invasive urothelial carcinoma of the bladder have poor survival after cystectomy. The EORTC 30994 trial aimed to compare immediate versus deferred cisplatin-based combination chemotherapy after radical cystectomy in patients with pT3-pT4 or N+ M0 urothelial carcinoma of the bladder. METHODS: This intergroup, open-label, randomised, phase 3 trial recruited patients from hospitals across Europe and Canada. Eligible patients had histologically proven urothelial carcinoma of the bladder, pT3-pT4 disease or node positive (pN1-3) M0 disease after radical cystectomy and bilateral lymphadenectomy, with no evidence of any microscopic residual disease. Within 90 days of cystectomy, patients were centrally randomly assigned (1:1) by minimisation to either immediate adjuvant chemotherapy (four cycles of gemcitabine plus cisplatin, high-dose methotrexate, vinblastine, doxorubicin, and cisplatin [high-dose MVAC], or MVAC) or six cycles of deferred chemotherapy at relapse, with stratification for institution, pT category, and lymph node status according to the number of nodes dissected. Neither patients nor investigators were masked. Overall survival was the primary endpoint; all analyses were by intention to treat. The trial was closed after recruitment of 284 of the planned 660 patients. This trial is registered with ClinicalTrials.gov, number NCT00028756. FINDINGS: From April 29, 2002, to Aug 14, 2008, 284 patients were randomly assigned (141 to immediate treatment and 143 to deferred treatment), and followed up until the data cutoff of Aug 21, 2013. After a median follow-up of 7.0 years (IQR 5.2-8.7), 66 (47%) of 141 patients in the immediate treatment group had died compared with 82 (57%) of 143 in the deferred treatment group. No significant improvement in overall survival was noted with immediate treatment when compared with deferred treatment (adjusted HR 0.78, 95% CI 0.56-1.08; p=0.13). Immediate treatment significantly prolonged progression-free survival compared with deferred treatment (HR 0.54, 95% CI 0.4-0.73, p<0.0001), with 5-year progression-free survival of 47.6% (95% CI 38.8-55.9) in the immediate treatment group and 31.8% (24.2-39.6) in the deferred treatment group. Grade 3-4 myelosuppression was reported in 33 (26%) of 128 patients who received treatment in the immediate chemotherapy group versus 24 (35%) of 68 patients who received treatment in the deferred chemotherapy group, neutropenia occurred in 49 (38%) versus 36 (53%) patients, respectively, and thrombocytopenia in 36 (28%) versus 26 (38%). Two patients died due to toxicity, one in each group. INTERPRETATION: Our data did not show a significant improvement in overall survival with immediate versus deferred chemotherapy after radical cystectomy and bilateral lymphadenectomy for patients with muscle-invasive urothelial carcinoma. However, the trial is limited in power, and it is possible that some subgroups of patients might still benefit from immediate chemotherapy. An updated individual patient data meta-analysis and biomarker research are needed to further elucidate the potential for survival benefit in subgroups of patients.

Doxorubicin alone versus intensified doxorubicin plus ifosfamide for first-line treatment of advanced or metastatic soft-tissue sarcoma: a randomised controlled phase 3 trial.

BACKGROUND: Effective targeted treatment is unavailable for most sarcomas and doxorubicin and ifosfamide-which have been used to treat soft-tissue sarcoma for more than 30 years-still have an important role. Whether doxorubicin alone or the combination of doxorubicin and ifosfamide should be used routinely is still controversial. We assessed whether dose intensification of doxorubicin with ifosfamide improves survival of patients with advanced soft-tissue sarcoma compared with doxorubicin alone. METHODS: We did this phase 3 randomised controlled trial (EORTC 62012) at 38 hospitals in ten countries. We included patients with locally advanced, unresectable, or metastatic high-grade soft-tissue sarcoma, age 18-60 years with a WHO performance status of 0 or 1. They were randomly assigned (1:1) by the minimisation method to either doxorubicin (75 mg/m(2) by intravenous bolus on day 1 or 72 h continuous intravenous infusion) or intensified doxorubicin (75 mg/m(2); 25 mg/m(2) per day, days 1-3) plus ifosfamide (10 g/m(2) over 4 days with mesna and pegfilgrastim) as first-line treatment. Randomisation was stratified by centre, performance status (0 vs 1), age (<50 vs ≥50 years), presence of liver metastases, and histopathological grade (2 vs 3). Patients were treated every 3 weeks till progression or unacceptable toxic effects for up to six cycles. The primary endpoint was overall survival in the intention-to-treat population. The trial is registered with ClinicalTrials.gov, number NCT00061984. FINDINGS: Between April 30, 2003, and May 25, 2010, 228 patients were randomly assigned to receive doxorubicin and 227 to receive doxorubicin and ifosfamide. Median follow-up was 56 months (IQR 31-77) in the doxorubicin only group and 59 months (36-72) in the combination group. There was no significant difference in overall survival between groups (median overall survival 12·8 months [95·5% CI 10·5-14·3] in the doxorubicin group vs 14·3 months [12·5-16·5] in the doxorubicin and ifosfamide group; hazard ratio [HR] 0·83 [95·5% CI 0·67-1·03]; stratified log-rank test p=0·076). Median progression-free survival was significantly higher for the doxorubicin and ifosfamide group (7·4 months [95% CI 6·6-8·3]) than for the doxorubicin group (4·6 months [2·9-5·6]; HR 0·74 [95% CI 0·60-0·90], stratified log-rank test p=0·003). More patients in the doxorubicin and ifosfamide group than in the doxorubicin group had an overall response (60 [26%] of 227 patients vs 31 [14%] of 228; p<0·0006). The most common grade 3 and 4 toxic effects-which were all more common with doxorubicin and ifosfamide than with doxorubicin alone-were leucopenia (97 [43%] of 224 patients vs 40 [18%] of 223 patients), neutropenia (93 [42%] vs 83 [37%]), febrile neutropenia (103 (46%) vs 30 [13%]), anaemia (78 [35%] vs 10 [5%]), and thrombocytopenia (75 [33%]) vs one [<1%]). INTERPRETATION: Our results do not support the use of intensified doxorubicin and ifosfamide for palliation of advanced soft-tissue sarcoma unless the specific goal is tumour shrinkage. These findings should help individualise the care of patients with this disease. FUNDING: Cancer Research UK, EORTC Charitable Trust, UK NHS, Canadian Cancer Society Research Institute, Amgen.

Occult lymph node metastases in patients with carcinoma invading bladder muscle: incidence after neoadjuvant chemotherapy and cystectomy vs after cystectomy alone.

OBJECTIVE: To investigate the effect of neoadjuvant chemotherapy (NAC) on the incidence of lymph node (LN) metastases in clinically node-negative (cN0) patients with carcinoma invading the bladder muscle (MIBC). PATIENTS AND METHODS: Between 1990 and 2012, 828 consecutive patients underwent radical cystectomy (RC) with extended pelvic LN dissection (ePLND), of whom 441 had cT2-4N0M0 stage disease. A total of 83 patients received NAC then underwent RC and 358 patients underwent RC only. The ePLND template and the indication for NAC remained the same during the study period. The incidence of occult LN metastases was compared between the groups. Unadjusted and adjusted odds ratios (ORs) were calculated to investigate the influence of NAC, cT stage, gender and the preoperative staging technique used (computed tomography [CT] or positron emission tomography/CT) on the occurrence of LN metastases. Overall survival (OS) and disease-specific survival were analysed using the Kaplan-Meier method. RESULTS: Patients in the NAC group more often had locally advanced MIBC than patients in the non-NAC group (cT3-4: 88.0 vs 30.2%). In the NAC group, 19.3% of patients had LN metastases vs 28.5% of the patients in the non-NAC group (P = 0.099). In the patients with cT3-4 disease, the occurrence of LN metastases was significantly lower in the NAC group than in the non-NAC group (21.9 vs 40.7%, respectively, P = 0.002). In multivariable analysis, adjusting for cT stage, gender and staging method, NAC was independently associated with a lower likelihood of LN metastases (OR: 0.41, 95% CI 0.21-0.79; P = 0.008). Among the patients with cT3-4 disease, the median OS was significantly longer in the NAC group than in the non-NAC group (68.0 vs 23.0 months, P = 0.047) CONCLUSION: These data suggest that, along with a downstaging effect on the primary bladder tumour, NAC is associated with a lower incidence of occult LN metastases at the time of RC.

Induction chemotherapy followed by surgery in node positive bladder cancer.

OBJECTIVE: To evaluate the outcome and prognostic factors of patients with node positive bladder cancer (NPBC), who were eligible for surgery and treated with induction chemotherapy. METHODS: All consecutive patients with NPBC, who were treated with at least 2 cycles of induction chemotherapy and initially scheduled for surgery, between 1990 and 2012, were identified from an institutional bladder cancer database. Induction chemotherapy consisted of MVAC (methotrexate, vinblastine, doxorubicin, and cisplatin) or gemcitabine with cisplatin (Gem/Cis) or carboplatin (Gem/Carbo). RESULTS: One hundred forty-nine patients with NPBC (mean age, 60 years; range, 31-79) were treated with induction chemotherapy. Median cancer-specific survival (CSS) was 20 months and 5-year CSS 29.2%. In case of complete pathologic response to induction chemotherapy (N = 40; 26.8%), median CSS was 127 months and 5-year CSS 63.5% (P <.0001). Clinical and pathologic responses to chemotherapy were predictive parameters with respect to CSS and recurrence-free survival. Combined local and nodal responses resulted in a significantly better outcome, compared with isolated nodal or local response (P <.0001). CONCLUSION: Prognosis for NPBC remains poor despite the use of induction chemotherapy. Nevertheless, in the present series, 1 of 4 patients showed complete pathologic response to induction chemotherapy with subsequently a significant CSS benefit (median CSS 127 months and 5-year CSS 63.5%). Clinical and pathologic responses to chemotherapy are predictive parameters for outcome.
