Background The ROSORC trial, a randomised, phase II trial comparing sorafenib plus interleukin (IL-2) versus sorafenib alone as first-line treatment of metastatic renal cell carcinoma (mRCC) failed to demonstrate differences in progression-free survival (PFS). Updated overall survival (OS) results are reported. Patients and methods In this study, 128 patients were randomised to receive sorafenib 400 mg twice daily plus subcutaneous IL-2 4.5 million international units (MIU) five times per week for 6 weeks every 8 weeks (arm A) or sorafenib alone (arm B). OS was estimated with the Kaplan–Meier method and compared with the two-sided log-rank test. Results After a median follow-up of 58 months (interquartile range: 28–63 months), the median OS was 38 and 33 months in arms A and B, respectively (P = 0.667). The 5-year OS was 26.3% [95% confidence interval (CI) 15.9–43.5) and 23.1% (95% CI 13.2–40.5) for the combination- and single-agent arm, respectively. Most of the patients who were refractory to first-line treatment were subsequently treated with different targeted agents; they had a median survival greater than expected. Conclusions This outcome suggests a synergistic effect of the subsequent therapies following sorafenib failure. ClinicalTrials.gov Identifier NCT00609401.

The aim of this study was to compare survival of resected and unresected patients in a large cohort of patients with metastases to the pancreas from renal cell carcinoma (PM-RCC). Data from 16 Italian centers involved in the treatment of metastatic RCC were retrospectively collected. The Kaplan–Meier and log-rank test methods were used to evaluate overall survival (OS). Clinical variables considered were sex, age, concomitant metastasis to other sites, surgical resection of PM-RCC, and time to PM-RCC occurrence. Overall, 103 consecutive patients with radically resected primary tumors were enrolled in the analysis. PM-RCCs were synchronous in only three patients (3 %). In 56 patients (54 %), the pancreas was the only metastatic site, whereas in the other 47 patients, lung (57 %), lymph nodes (28 %), and liver (21 %) were the most common concomitant metastatic sites. Median time for PM-RCC occurrence was 9.6 years (range 0–24 years) after nephrectomy. Surgical resection of PM-RCC was performed in 44 patients (median OS 103 months), while 59 patients were treated with tyrosine kinase inhibitors (TKIs; median OS 86 months) (p = 0.201). At multivariate analysis, Memorial Sloan Kettering Cancer Center risk group was the only independent prognostic factor. None of the other clinical variables, such as age, sex, pancreatic surgery, or the presence of concomitant metastases, were significantly associated with outcome in PM-RCC patients. The presence of PM-RCC is associated with a long survival, and surgical resection does not improve survival in comparison with TKI therapy. However, surgical resection leads to a percentage of disease-free PM-RCC patients.

BackgroundUntil now, no robust data supported the efficacy, safety and recommendation for influenza vaccination in patients with cancer receiving immune checkpoint inhibitors (ICIs).MethodsThe prospective multicenter observational INfluenza Vaccine Indication During therapy with Immune checkpoint inhibitors (INVIDIa-2) study investigated the clinical effectiveness of influenza vaccination in patients with advanced cancer receiving ICIs, enrolled in 82 Italian centers from October 2019 to January 2020. The primary endpoint was the time-adjusted incidence of influenza-like illness (ILI) until April 30, 2020. Secondary endpoints regarded ILI severity and vaccine safety.ResultsThe study enrolled 1279 patients; 1188 patients were evaluable for the primary endpoint analysis. Of them, 48.9% (581) received influenza vaccination. The overall ILI incidence was 8.2% (98 patients). Vaccinated patients were significantly more frequently elderly (pvs 29.8%, p=0.027). ILI lethality was, respectively, 0% in vaccinated and 4.3% in unvaccinated patients. Vaccine-related adverse events were rare and mild (1.5%, grades 1–2).ConclusionThe INVIDIa-2 study results support a positive recommendation for influenza vaccination in patients with advanced cancer receiving immunotherapy.

Cabozantinib is approved for the treatment of renal cell carcinoma (RCC). However, prognostic factors are still lacking in this context. The aim of this study was to evaluate prognostic factors in RCC patients treated with second- or third-line cabozantinib. A multicenter retrospective real-world study was conducted, involving 32 worldwide centers. A total of 237 patients with histologically confirmed clear-cell and non-clear-cell RCC who received cabozantinib as second- or third-line therapy for metastatic disease were included. We analyzed overall survival (OS), progression-free survival (PFS) and time-to-strategy failure (TTSF) using Kaplan&ndash, Meier curves. Cox proportional models were used at univariate and multivariate analyses.The median PFS and OS of cabozantinib were 7.76 months (95% CI 6.51&ndash, 10.88) and 11.57 months (95% CI 10.90&ndash, not reached (NR)) as second-line and 11.38 months (95% CI 5.79&ndash, NR) and NR (95% CI 11.51&ndash, NR) as third-line therapy. The median TTSF and OS were 11.57 and 15.52 months with the sequence of cabozantinib&ndash, nivolumab and 25.64 months and NR with nivolumab&ndash, cabozantinib, respectively. The difference between these two sequences was statistically significant only in good-risk patients. In the second-line setting, hemoglobin (Hb) levels (HR= 2.39, 95% CI 1.24&ndash, 4.60, p = 0.009) and IMDC (International Metastatic Renal Cell Carcinoma Database Consortium) group (HR = 1.72, 95% CI 1.04&ndash, 2.87, p = 0.037) were associated with PFS while ECOG-PS (HR = 2.33, 95%CI, 1.16&ndash, 4.69, p = 0.018) and Hb levels (HR = 3.12, 95%CI 1.18&ndash, 8.26, p = 0.023) correlated with OS at multivariate analysis, while in the third-line setting, only Hb levels (HR = 2.72, 95%CI 1.04&ndash, 7.09, p = 0.042) were associated with OS. Results are limited by the retrospective nature of the study.This real-world study provides evidence on the presence of prognostic factors in RCC patients receiving cabozantinib.

Purpose: Renal cell carcinoma (RCC) is the most common tumor of the kidney. Considering the TNM classification of 2009, locally advanced and metastatic diseases are included in the groups stage III and IV. The surgical treatment of these tumors could be divided into 3 categories: (1) curative (nephrectomy and/or metastasectomy), (2) cytoreductive, and (3) palliative. Targeted agents showed impressive antitumor efficacy and prolongation of progression-free survival. The integration between target therapy and surgery in patients with locally advanced or metastatic RCC has sometimes facilitated surgery. We aimed to evaluate patients’ response to tyrosine kinase inhibitor (TKI) therapy and the feasibility of surgery after that and to observe complications related to surgery. Methods: From February 2007 to September 2014 in the Istituto Tumori of Milan, IRCCS, we selected patients with locally advanced or metastatic diseases, treated with target therapy before surgery (which comprised nephrectomy or partial nephrectomy, cytoreductive surgery, and metastasectomy) and cryoablation. Results: We selected 33 patients who underwent surgery after TKI therapy. As for response to TKIs, 20 patients (60%) had stable disease, 9 patients (28%) had a partial response, and 4 patients (12%) had progressive disease. A total of 17 patients (51%) presented complications directly or indirectly related to surgery and most of those were classified as grade II Clavien-Dindo score. Conclusions: The association between TKI and surgery seems to have no contraindications. Our dataset provides an example of how surgery after TKI is possible in locally advanced metastatic tumor and does not have an excessive rate of postoperative complications.

Collecting ducts carcinoma (CDC) is a rare and aggressive histological subtype of renal cancer accounting for only 1% of renal tumors. Usually patients present in bad clinical conditions due to a symptomatic disease with synchronous metastasis. Due to the rarity of CDC, data from prospective trials evaluating the best treatment for these patients are limited. The prognosis is poor with a median overall survival of around 11 months for patients with metastatic disease. The best treatment option today is considered a doublet chemotherapy with platinum salt plus gemcitabine as a result from a prospective phase II trial, but survival outcomes remain unsatisfactory. The interest in the in-depth understanding the biology of this orphan disease is growing, leading to find potential new biological-driven treatment approaches. Here we review the up-to-date literature evidences to address the best management of this rare and unfavorable clinical condition.

Background The purpose of the present retrospective analysis was to describe the trends in exposure to multiple lines of treatment and overall survival (OS) in patients with metastatic renal cell carcinoma (mRCC) who started therapy in 2 different periods (period 1, 2004-2010; and period 2, 2011-2017). Patients and Methods The proportion of patients who received subsequent lines of treatment after disease progression was compared between the 2 groups. OS was measured from the start of first-line treatment for metastatic disease to death or the last follow-up examination. Both univariate and multivariate analyses were performed. Results A total of 500 patients were included in the study; 274 started treatment in period 1 and 226 in period 2. Of those patients who stopped first-line treatment because of disease progression, the patients in period 2 had a greater conditional probability to receive second- and third-line treatment compared with patients in period 1 (77.2% vs. 63.7%; odds ratio [OR], 1.93; 95% confidence interval [CI], 1.20-3.11; P = .0065; and 69.6% vs. 48.1%; OR, 2.48; 95% CI, 1.40-4.40; P = .002, respectively). The median OS improved from 22.8 months for patients in period 1 to 38.2 months for patients in period 2 (univariate analysis: hazard ratio, 0.65; 95% CI, 0.50-0.83; P = .001). Conclusion Patients who started treatment during the past 5 years were exposed to a greater number of treatment lines compared with patients treated before 2011. Our data suggest that the increase of treatment options available and clinician expertise could be associated with better outcomes.

Immunotherapy for the treatment of cancer has made significant progresses over the last 20 years. Multiple efforts have been attempted to restore immune-mediated tumor elimination, leading to the development of several targeted immunotherapies. Data from recent clinical trials suggest that these agents might improve the prognosis of patients with advanced genito-urinary (GU) malignancies. Nivolumab has been the first immune checkpoint-inhibitor approved for pre-treated patients with metastatic renal cell carcinoma. Pembrolizumab and atezolizumab have shown promising results in both phase I and II trials in urothelial carcinoma. Brentuximab vedotin has demonstrated early signals of clinical activity and immunomodulatory effects in highly pre-treated patients with testicular germ cell tumors. In this review, we have summarized the major clinical achievements of immunotherapy in GU cancers, focusing on immune checkpoint blockade as well as the new immunomodulatory monoclonal antibodies (mAbs) under clinical evaluation for these malignancies.

Objectives Approximately one-third of the metastatic germ cell tumors (GCT) in patients are classified as intermediate-risk metastatic GCT, and available guidelines recommend the same treatment of poor-risk cases. Yet the prognosis of these patients is heterogeneous, and consequently refining the intensity of treatment is warranted. We aimed to address the heterogeneity of this category by providing a proof of principle for reclassification attempt. Patients and methods Data on consecutive patients with intermediate-risk metastatic GCT and who received treatment at Fondazione INT Milano in the time frame between February 1980 and March 2014 were collected. Cox regression analyses were done, evaluating potential prognostic factors for overall survival (OS, primary end point) to first-line therapy. Each factor was evaluated in a multivariable model. Recursive partitioning was performed to define prognostic risk groups. Results A total of 224 patients were suitable for the present analysis. Median age was 26 years (interquartile range: 22–31), 11 patients (4.9%) had a retroperitoneal primary tumor, 6 yielded seminomatous histology, 85 (37.9%) had lung metastases, and 58 (25.9%) had bulky (i.e.,≥10 cm) retroperitoneal lymph nodes. Patients received cisplatin, bleomycin, and etoposide (PEB, n = 199) or vinblastine (PVB, n = 23); however, 2 patients received other treatments. Median follow-up was 135 months (interquartile range: 81–223). Globally, 5-year progression-free survival and OS rates were 72.8% (95% CI: 67.1–79.0) and 86.2% (81.7–91.0), respectively. In the multivariable model for OS, elevated alfa fetoprotein (AFP) level was the only significant prognostic factor (hazard ratio = 1.48, 95% CI: 1.12–1.96). The 2 separate prognostic groups with differential OS outcomes were identified based on the cutoff level of 6,200 IU/ml. The 10-year OS rate was 55.6% (95% CI: 36.6–84.3), and it was 86.7% (95% CI: 82.0–91.7) for those with AFP levels more than (n = 19, 8.5%) and less than (n = 205, 91.5%) the cutoff, respectively. Conclusions A small fraction of patients with highly elevated AFP levels have an OS approximating the poor prognostic category, whereas most of them are close to good-risk cases. This might have implications to select outlier patients for clinical trials and molecular characterization.

In this retrospective study, patients with poor-prognosis germ cell tumors (GCT) treated from a single referral center demonstrated high survival estimates that were stable through the years. Indeed, the major clinical implication is that using the available prognostic classification of metastatic GCT cannot allow the recognition of patients with a true chemoresistant disease. Moreover, the prognostic effect of treating patients with disseminated disease in referral centers should be further assessed. Background: Survival estimates with first-line treatment for patients with metastatic poor prognosis germ cell tumors (GCT) are still suboptimal in the literature. We conducted a retrospective study to evaluate the outcome of patients referred to our tertiary cancer center. Patients and Methods: A retrospective analysis was conducted on patients who received at least first-line chemotherapy at our center. Distribution of clinical characteristics was evaluated in the periods < 1997, 1997 to 2001, 2001 to 2006, and 2007 to 2013. The Kaplan-Meier method was used to estimate progression-free (PFS) and overall survival (OS). Univariable and multivariable Cox models with prespecified clinical variables were undertaken for PFS and OS. All tests and confidence intervals were 2-sided and set at a P = .05 level of significance. Results: Between 1982 and 2013, 168 patients were identified. The median age was 27 years (inter-quartile range [IQR], 22-34). The presence of liver, bone, or brain metastases trended to greater incidence from 1997 onward (27.5% < 1997 to 55.6% in 2007-2013; chi(2) P = .054). Median follow-up was 102 (IQR, 63-166) months. Global 5-year PFS was 48.5% (95% confidence interval [CI], 41.5-56.8) and OS was 63.2% (95% CI, 56.0-71.2). In multivariable analysis, treatment period was not significantly associated with either PFS (overall P = .229) or OS (overall P = .216). Conclusion: In this single-center series of consecutive poor prognosis GCT we could observe greater PFS and OS than the historical estimates. This observation was independent from the period of treatment. Based on the present results, studies focused on improving the outcome in the sole poor-risk cohort should be discouraged. Results were biased by their retrospective quality.

Aims and Background The introduction of agents targeting vascular endothelial growth factor has radically changed the approach to metastatic renal cell carcinoma (mRCC): sunitinib and pazopanib are now the standard first-line therapy in mRCC. At sunitinib failure, second-line axitinib or everolimus or sorafenib should be considered to improve the clinical outcome. No data are available for a third-line tyrosine kinase inhibitor (TKI) after 2 previous lines of therapy with TKIs. At pazopanib failure, no prospective data are available. Study Design The TOKIO study was designed to evaluate progression-free survival, safety, and efficacy of third-line therapy with TKI in 44 patients already treated with 2 previous lines of TKIs in 10 Italian centers, and relapsed from sunitinib-axitinib (group A) or pazopanib-sorafenib (group B). Standard treatment is sorafenib in group A and sunitinib in group B, administered until disease progression or unacceptable toxicity. Secondary endpoints include the evaluation of overall survival, safety, and quality of life.

Temsirolimus is an inhibitor of the mammalian target of rapamycin (mTOR) kinase, a protein that has been shown to be particularly active in metastatic renal cell carcinoma (mRCC) with poor prognosis. Therefore, temsirolimus should be considered as the first-line treatment indicated in mRCC patients classified as poor risk. The benefits of temsirolimus are not limited to an increased survival but are also related to a better quality of life, which is certainly one of the most important aspects in the clinical management of these frail patients. Temsirolimus is a well-tolerated treatment, and the most frequent adverse events are manageable with supportive care. To this end, the identification of predictive factors of response to temsirolimus could help us to better select patients and obtain a more tailored clinical management of mRCC.

Background: Everolimus is a mammalian target of rapamycin (mTOR) inhibitor approved for the treatment of metastatic renal cell carcinoma (mRCC). We aimed to assess the association between the baseline values and treatmentrelated modifications of total serum cholesterol (C), triglycerides (T), body mass index (BMI), fasting blood glucose level (FBG) and blood pressure (BP) levels and the outcome of patients treated with everolimus for mRCC. Methods: 177 patients were included in this retrospective analysis. Time to progression (TTP), clinical benefit (CB) and overall survival (OS) were evaluated. Results: Basal BMI was significantly higher in patients who experienced a CB (p=0,0145). C, T and C +T raises were significantly associated with baseline BMI (p=0.0412, 0.0283 and 0.0001). Median TTP was significantly longer in patients with T raise compared to patients without T (10 vs 6, p =0.030), C (8 vs 5, p =0.042) and C+T raise (10.9 vs 5.0, p=0.003). At the multivariate analysis, only C+T increase was associated with improved TTP (p=0.005). T raise (21.0 vs 14.0, p=0.002) and C+T increase (21.0 vs 14.0, p=0.006) were correlated with improved OS but were not significant at multivariate analysis. Conclusion: C+T raise is an early predictor for everolimus efficacy for patients with mRCC.

Background Two mTOR inhibitors, TEM and EVE, proved to be active in mRCC but have never been compared in a prospective trial. We aimed to compare their effectiveness in mRCC patients previously treated with a vascular endothelial growth factor receptor tyrosine kinase inhibitor, and performed a systematic review and meta-analysis of available evidence. Materials and Methods The MEDLINE/PubMed database was reviewed for studies that compared EVE with TEM from January 2006 to May 2014. Summary hazard ratio (HR) for overall survival (OS) and time to treatment failure (TTF) were calculated using random and fixed effects models depending on the heterogeneity of included studies. Statistical heterogeneity was assessed using the χ 2 test, and inconsistency was quantified with the I 2 statistic. Publication bias was evaluated using the Begg and Egger test. Results Four studies were included in the meta-analysis; data of 937 patients were available: 545 received EVE and 392 TEM. Among the included patients, 863 [92%] were treated with sunitinib and 74 [8%] with pazopanib or sorafenib as first-line therapy. In the overall population, treatment with EVE decreased the risk of death by 26% over TEM (HR, 0.74; 95% confidence interval [CI], 0.59-0.93; P = .008). The TTF was evaluable in 692 patients; in this group, treatment with EVE decreased the risk of treatment failure by 30% (HR, 0.70; 95% CI, 0.56-0.88; P = .002). No significant heterogeneity or publication bias was found for OS and TTF. Conclusion In this analysis, we compared EVE with TEM as second-line therapy in mRCC, and report a significant difference between mTOR inhibitors, even if these results need to be confirmed in a prospective trial.

We report the case of a young woman diagnosed with metastatic urachal carcinoma. A multimodal approach was used for the management of this patient. Due to disease progression despite surgery and two different chemotherapy regimens (neoadjuvant capecitabine + irinotecan + oxaliplatin and docetaxel + cisplatin after surgery), treatment with sunitinib was eventually started. Treatment with sunitinib resulted in stable disease and improvement of symptoms. Sunitinib was discontinued due to the occurrence of metrorrhagia, and restarted one week later. Disease eventually progressed and the patient died 18 months after the onset of symptoms. This is the first report on the use of sunitinib for the management of urachal carcinoma and provides initial evidence supporting the use of targeted therapy in this setting.

Though uncommon, the collecting duct carcinoma (CDC) of Bellini is a very aggressive primary renal tumour occurring in less than 1% of all renal cell carcinoma (RCC) cases. This rare subtype was always excluded from the prospective trials with targeted therapies. Few data so far available concern the subgroup analyses from the expanded access programs with sorafenib and sunitinib, and from temsirolimus randomized study.From December 2004 to May 2010, 333 patients with advanced RCC have been treated in our Institution with targeted therapies: of these, 7 (2.6%) were affected by CDC. General characteristics, symptoms, pathological features, treatments and patients' outcome were recorded.All patients affected by CDC received targeted agents as first-line therapy: more precisely, 4 patients were treated with sorafenib, 2 with temsirolimus and 1 with sunitinib. After progression 2 patients received a second-line treatment with sunitinib. No patients were alive at 5 years. Five patients developed early progression of disease with a very short 4-month survival, while 2 cases had a long-lasting disease control with an overall survival time accounting for 49 and 19 months, respectively. Treatment-related adverse events were manageable consisting of fatigue, diarrhoea, hand-foot syndrome, hypertension and anemia, the latter being the most frequent. No treatment discontinuations due to adverse event were needed.This investigation shows that targeted agents are safe, displaying some degree of activity in CDCs: therefore, they could be considered as an alternative in patients not eligible to chemotherapy regimens. Further studies including biomarkers as predictive factors of tumour biology and clinical features are required to improve the management of this challenging disease.
