RESUMEN
BACKGROUND: Circulating tumor cells (CTCs) correlate with adverse prognosis in patients with breast, colorectal, lung, and prostate cancer. Little data are available for renal cell carcinoma (RCC). MATERIALS AND METHODS: We designed a multicenter prospective observational study to assess the correlation between CTC counts and progression-free survival (PFS) in patients with metastatic RCC treated with an antiangiogenic tyrosine kinase inhibitor as a first-line regimen; overall survival (OS) and response were secondary objectives. CTC counts were enumerated by the CellSearch system at four time points: day 0 of treatment, day 28, day 56 and then at progression, or at 12 months in the absence of progression. RESULTS: One hundred ninety-five eligible patients with a median age of 69 years were treated with sunitinib (77.5%) or pazopanib (21%). At baseline, 46.7% of patients had one or more CTCs per milliliter (range, 1 to 263). Thirty patients had at least three CTCs, with a median PFS of 5.8 versus 15 months in the remaining patients (p = .002; hazard ratio [HR], 1.99), independently of the International Metastatic RCC Database Consortium score at multivariate analysis (HR, 1.91; 95% confidence interval [CI], 1.16-3.14). Patients with at least three CTCs had a shorter estimated OS of 13.8 months versus 52.8 months in those with fewer than three CTCs (p = .003; HR, 1.99; multivariate analysis HR, 1.67; 95% CI, 0.95-2.93). Baseline CTC counts did not correlate with response; neither did having CTC sequencing counts greater than or equal to one, two, three, four, or five. CONCLUSION: We provide prospective evidence that the presence of three or more CTCs at baseline is associated with a significantly shorter PFS and OS in patients with metastatic RCC. IMPLICATIONS FOR PRACTICE: This prospective study evaluated whether the presence of circulating tumor cells (CTCs) in the peripheral blood correlates with activity of first-line tyrosine kinase inhibitors in metastatic renal cell carcinoma (RCC). This study demonstrated that almost half of patients with metastatic RCC have at least one CTC in their blood and that those patients with at least three CTCs are at increased risk of early progressive disease and early death due to RCC. Studies incorporating CTC counts in the prognostic algorithms of metastatic RCC are warranted.

Background Oral metronomic therapy (OMV) is particularly suitable for palliative care, and schedules adapted for unfit patients are advisable. This study investigated the effects of oral vinorelbine given every other day without interruption and its pharmacokinetic profile in patients with advanced lung cancer. Materials and Methods Ninety-two patients received OMV at doses of 20, 30 or 50 mg. Toxic events, clinical benefit and overall survival were analysed. Blood pharmacokinetics were evaluated in 82 patients. Results Median treatment duration and overall survival were 15 (range 1.3-144) and 32.3 weeks, respectively; fourty-eight (60%) patients experienced clinical benefit. Outcomes were unrelated to previous therapies, age, histology or comorbidities. Toxicity was associated with higher blood concentrations of the drug. Pharmacokinetics were stable for up to two years, and were not influenced by treatment line or age. Conclusions OMV produced non-negligible survival in patients and also showed stable long-term blood concentrations. The schedule of 20-30 mg every other day without interruption gave good tolerability and clinical benefit.

Despite improvements in systemic chemotherapy (CT), the prognosis of metastatic adenocarcinoma of the gastroesophageal junction remains poor. Over the years, new targeting agents have become available and were tested, with or without CT, in first or subsequent lines of therapy. The epidermal growth factor receptor family was targeted with monoclonal antibodies (MoAbs) (trastuzumab, cetuximab, panitumumab) and tyrosin kinase inhibitors (TKIs) (lapatinib, erlotinib, gefitinib). Only trastuzumab, in combination with cisplatin and fluoropyrimidines, significantly improved overall survival (OS) in first-line therapy (13.8 vs. 11.1 months). Angiogenesis also was targeted with MoAbs (bevacizumab and ramucirumab); ramucirumab, a vascular endothelial growth factor-receptor 2 antagonist, enhanced OS in two phase III studies in the first (9.6 vs. 7.4 months) and subsequent lines of treatment (5.2 vs. 3.8 months), while the bevacizumab study was negative. TKIs (sunitinib, sorafenib, regorafenib, apatinib) were tested in this setting in phase II studies in the second/third line, only showing modest antitumor activity. The hepatocyte growth factor receptor (MET) was targeted in untreated patients in a phase III trial with MoAb rilotumumab, with or without CT, but the study was stopped because of mortality excess in the rilotumumab arm. Mammalian target of rapamycin (MTOR) pathway inhibition with everolimus was tested in pretreated patients in a placebo-controlled phase III trial who failed to improve OS (5.4 vs. 4.3 months). In conclusion, considering the modest survival gain obtained overall, the high cost of these therapies and the quality of life issue must be primarily considered in treating these patients.

BACKGROUND: Pretreated metastatic breast cancer (MBC) remains a formidable challenge with unmet needs both in terms of prolonged survival and quality-of-life-related issues. METHODS: We collected data from 27 MBC patients treated with gemcitabine and oxaliplatin (GEMOX) at our institution between June 2009 and April 2015. The patients were heavily pretreated, and all had previously been exposed to anthracyclines and taxanes. RESULTS: We achieved a complete response in 1 patient (4%), a partial response in 7 patients (26%) and stable disease in 12 patients (44%), while 6 patients (22%) experienced progressive disease. The response of 1 patient (4%) could not be evaluated because she interrupted her treatment during the first cycle due to a major reaction to oxaliplatin. We observed grade 4 hypertransaminasaemia in only 1 patient (4%) and grade 2 neuropathy in 16 patients (59%). Grade 3 leuconeutropenia was observed in 5 patients (18%). The median progression-free survival was 5.9 months and the median overall survival was 9.6 months. CONCLUSIONS: GEMOX is an efficient and well-tolerated salvage regimen for MBC patients.

OBJECTIVE: To assess the safety and efficacy of abiraterone acetate (AA) in patients with metastatic castration-resistant prostate cancer (mCRPC) treated in a compassionate named patient programme (NPP). PATIENTS AND METHODS: We retrospectively reviewed the clinical records of patients with mCRPC treated with AA at the standard daily oral dose of 1000 mg plus prednisone 10 mg/day in 19 Italian hospitals. RESULTS: We assessed 265 patients with mCRPC treated with AA. The most frequent (>1%) grade 3-4 toxicities were anaemia (4.2%), fatigue (4.2%), and bone pain (1.5%). The median progression-free survival was 7 months; median overall survival was 17 months after starting AA, and 35 months after the first docetaxel administration. Our study reproduced the clinical outcomes reported in the AA pivotal trial, including those relating to special populations such as the elderly, patients with a poor performance status, symptomatic patients, and patients with visceral metastases. CONCLUSIONS: Our data show the safety and activity of AA when administered outside clinical trials, and confirm the findings of the post-docetaxel pivotal trial in the patients as a whole population and in special populations of specific interest.

Importance: There exists considerable biological and clinical variability between histologic variants of metastatic renal cell carcinoma (mRCC). Data reporting on patterns of metastasis in histologic variants of mRCC are sparse. Objective: To characterize sites of metastasis and their association with survival across the 3 most common histologic variants of mRCC: clear cell (ccRCC), papillary (pRCC), and chromophobe (chrRCC). Design, Setting, and Participants: In this multicenter, international cohort study, the International mRCC Database Consortium (IMDC) database was used to identify consecutive patients starting systemic therapy for mRCC between 2002 and 2019. Patients with mixed histologic subtype were excluded. Statistical analysis was performed from February to June 2020. Exposures: Data regarding histologic subtype and sites of metastatic involvement at the time of first systemic therapy initiation were collected. Main Outcomes and Measures: The primary outcomes were prevalence of metastatic site involvement and overall survival (OS) from time of systemic therapy initiation. Patients with multiple sites of metastatic involvement were included in analyses of all groups to which they had metastases. Results: A total of 10â¯105 patients were eligible for analysis. Median (interquartile range) age at diagnosis was 60 (53-67) years, 7310 (72.4%) were men and 8526 (84.5%) underwent nephrectomy. Of these, 9252 (92%) had ccRCC, 667 (7%) had pRCC, and 186 (2%) had chrRCC. The median number of sites of metastasis was 2 (range, 0-7). In ccRCC, the most common sites of metastasis were lung (70%; 6189 of 8804 patients [448 missing]), lymph nodes (45%; 3874 of 8655 patients [597 missing]), bone (32%; 2847 of 8817 patients [435 missing]), liver (18%; 1560 of 8804 [448 missing]), and adrenal gland (10%; 678 of 6673 patients [2579 missing]). Sites of metastasis varied between subtypes. Lung, adrenal, brain, and pancreatic metastases were more frequent in ccRCC, lymph node involvement was more common in pRCC, and liver metastases were more frequent in chrRCC. Median OS for ccRCC varied by site of metastatic involvement, ranging between 16 months (95% CI, 13.7-18.8 months) for the pleura and 50 months (95% CI, 41.1-55.5 months) for the pancreas. Compared with ccRCC, patients with pRCC tended to have lower OS, regardless of metastatic site. Conclusions and Relevance: Sites of metastatic involvement differ according to histologic subtype in mRCC and are associated with OS. These data highlight the clinical and biological variability between histologic subtypes of mRCC. Patterns of metastatic spread may reflect differences in underlying disease biology. Further work to investigate differences in immune, molecular, and genetic profiles between metastatic sites and histologic subtypes is encouraged.

BACKGROUND: The use of cytoreductive nephrectomy (CN) selectively for patients who show a favorable response to upfront systemic therapy may be an approach to select optimal candidates with metastatic renal cell carcinoma (mRCC) who are most likely to benefit. OBJECTIVE: We sought to characterize outcomes of deferred CN (dCN) after upfront sunitinib, outcomes relative to sunitinib alone, and outcomes of CN followed by sunitinib. DESIGN, SETTING, AND PARTICIPANTS: We used the prospectively maintained International mRCC Database Consortium (IMDC) database to identify patients with newly diagnosed mRCC (2006-2018). INTERVENTION: Sunitinib alone, upfront CN followed by sunitinib, sunitinib followed by dCN. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Outcomes were overall survival (OS) and time to sunitinib treatment failure (TTF). Kaplan-Meier and multivariable Cox regression analyses were performed; dCN was analyzed as a time-varying covariate to account for immortal time bias. RESULTS AND LIMITATIONS: We evaluated 1541 patients, of whom 651 (42%) received sunitinib alone, 805 (52%) underwent CN followed by sunitinib, and 85 (5.5%) received sunitinib followed by dCN, at a median of 7.8 mo from diagnosis. Median OS periods for patients treated with sunitinib alone, CN followed by sunitinib, and sunitinib followed by dCN were 10, 19, and 46 mo, respectively, while the median TTF values were 4, 8, and 13 mo, respectively. In multivariable regression analyses, sunitinib followed by dCN was significantly associated with improved OS (hazard ratio [HR] = 0.45, 95% confidence interval [CI] 0.33-0.60, p < 0.001) and TTF (HR = 0.62, 95% CI 0.46-0.85, p = 0.003) versus sunitinib alone. Among CN-treated patients, sunitinib followed by dCN was associated with improved OS (HR = 0.52, 95% CI 0.39-0.70, p < 0.001) and TTF (HR = 0.71, 95% CI 0.56-0.90, p = 0.005) compared with upfront CN followed by sunitinib. In various sensitivity analyses, dCN remained significantly associated with improved OS and TTF. CONCLUSIONS: Patients who received dCN were carefully selected and achieved long OS. With these benchmark outcomes, optimal selection criteria need to be identified and confirmation of the role of dCN in a clinical trial is warranted. PATIENT SUMMARY: We characterized benchmark survival outcomes for patients with metastatic kidney cancer treated with sunitinib alone, nephrectomy (kidney removal) followed by sunitinib, and sunitinib followed by nephrectomy. Patients who had their nephrectomy after an initial course of sunitinib had prolonged survival.

Recently cabozantinib, a tyrosine kinase inhibitor with activity against VEGF, MET, AXL, and downregulating cathepsin K in vitro, has been proposed for the treatment of advanced clear and non-clear renal cell carcinomas. Since it is well known that cathepsin K is expressed in the majority of MiT family translocation renal cell carcinomas, we investigated cathepsin K, MET, AXL, and VEGF in a large series of those tumours, looking for possible predictive markers. We collected the clinicopathological features of 34 genetically confirmed MiT family translocation renal cell carcinomas [26 Xp11 and 8 t(6;11) renal cell carcinomas] and studied them using an immunohistochemical panel including PAX8, cathepsin K, HMB45, Melan-A, CD68 (PG-M1), CK7, CA9, MET, AXL and by FISH for VEGFA and MET. Cathepsin K was expressed in 14 of 26, HMB45 in 8 of 25, and Melan-A in 4 of 23 Xp11 renal cell carcinomas, whereas labelling for CK7 and CA9 was minimal. In t(6;11) renal cell carcinoma, cathepsin K and melanogenesis markers were constantly positive, whereas CK7 and CA9 were negative. None of the 34 carcinomas showed CD68 (PG-M1) and AXL expression. One aggressive Xp11 renal cell carcinoma showed increased VEGFA gene copy number (4-5 copies) with concurrent gains of TFE3 and TFEB. None of the 34 carcinomas showed MET gene amplification, whereas staining for MET was found in 7 of 8 t(6;11) and in 16 of 24 Xp11 renal cell carcinomas, and in the latter cases, when the expression was >50%, correlated with aggressiveness (p=0.0049). In Xp11 renal cell carcinomas, the aggressiveness was also correlated with larger tumour size (p=0.0008) and the presence of necrosis (p=0.027) but not nucleolar grading (p=1). Interestingly, in patients with tumours exhibiting two of three parameters (necrosis, larger tumour size and MET immunolabelling >50%) an aggressive clinical behaviour was observed in 88% of cases. In conclusion, cathepsin K, CD68 (PG-M1), CK7, CA9, and PAX8 is a useful panel for the diagnosis. Larger tumour size, the presence of necrosis and MET immunohistochemical expression correlate with aggressive behaviour in Xp11 renal cell carcinomas, especially in combination. VEGF, MET, cathepsin K but not AXL may be potential predictive markers for targeted therapy in MiT family translocation renal cell carcinomas.

BACKGROUND: Patients with metastatic renal cell carcinoma (mRCC) may present with primary metastases (synchronous disease) or develop metastases during follow-up (metachronous disease). The impact of time to metastasis on patient outcome is poorly characterised. OBJECTIVE: To characterise overall survival (OS) and time to treatment failure (TTF) based on time to metastasis in mRCC patients treated with targeted therapy (tyrosine kinase inhibitors [TKIs]). DESIGN, SETTING, AND PARTICIPANTS: We used the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) to compare synchronous (metastases within ≤3 mo of initial diagnosis of cancer) versus metachronous disease (evaluated by >3-12 mo, >1-2â¯yr, >2-7â¯yr, and >7â¯yr intervals). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: OS and TFF were assessed using Kaplan-Meier curves. Cox multivariable regressions analyses (MVAs) were adjusted for baseline factors. RESULTS AND LIMITATIONS: Of 7386 patients with mRCC treated with first-line TKIs, 3906 (53%) and 3480 (47%) had synchronous and metachronous metastasis, respectively. More patients with synchronous versus metachronous disease had higher T stage (T1-2: 19% vs 34%), N1 disease (21% vs 6%), presence of sarcomatoid differentiation (15.8% vs 7.9%), Karnofsky performance status <80 (25.9% vs 15.1%), anaemia (62.5% vs 42.3%), elevated neutrophils (18.9% vs 10.9%), elevated platelets (21.6% vs 11.4%), bone metastases (40.4% vs 29.8%), and IMDC poor risk (40.6% vs 11.3%). Synchronous versus metachronous disease by intervals >3-12 mo, >1-2â¯yr, >2-7â¯yr, and >7â¯yr correlated with poor TTF (5.6 mo vs 7.3, 8.0, 10.8, and 13.3 mo, pâ¯<⯠0.0001) and poor OS (median 16.7 mo vs 23.8, 30.2, 34.8, and 41.7 mo, pâ¯<⯠0.0001). In MVAs, the adjusted hazard ratios (95% confidence intervals) were 1.00 (reference), 0.98 (0.90-1.06), 0.81 (0.73-0.91), 0.74 (0.68-0.81), and 0.60 (0.54-0.67), respectively, for OS (pâ¯<⯠0.0001), and 1.00 (reference), 0.99 (0.92-1.06), 0.98 (0.90-1.07), 0.83 (0.77-0.89), and 0.66 (0.60-0.72), respectively, for TTF (pâ¯<⯠0.0001). Data were collected retrospectively. CONCLUSIONS: Timing of metastases after initial RCC diagnosis may impact the outcomes from targeted therapy in mRCC. PATIENT SUMMARY: We looked at the impact of the timing of metastatic outbreak on survival outcomes in kidney cancer patients treated with targeted therapy. We found that the longer time to metastatic development was associated with improved outcome.

PURPOSE: This study investigated correlations of the clinical outcomes of oral metronomic vinorelbine (VNR) with VNR pharmacokinetics and MDR1 polymorphisms. METHODS: Eighty-two patients with metastatic non-small cell lung cancer (NSCLC) unfit for standard chemotherapy were treated with VNR at the oral doses of 20-30 mg every other day or 50 mg three times a week. They had a performance status (PS) ≤ 3, were > 70-year-old and drug-naïve or cisplatin-pretreated. MDR1 2677G > T and 3435C > T polymorphisms were analysed and blood concentrations of VNR and desacetyl-VNR (dVNR: active metabolite) assayed. Overall survival (OS), treatment duration and drug-related toxicity were the main endpoints. RESULTS: Median OS and treatment duration were 27 weeks (range 1.3-183) and 15 weeks (range 1.3-144), respectively. OS was directly correlated with the duration of VNR treatment and number of therapy lines after VNR treatment (multiple linear regression: adjusted r2 = 0.71; p < 0.00001). Neither MDR1 genotypes nor VNR/dVNR concentrations predicted OS. VNR blood levels were positively correlated with platelet counts (r2 = 0.12; p = 0.0036). Patients who had long-term benefit (treated for ≥ 6 month without toxicity) showed lower VNR concentrations than those who had not. Twelve patients stopped therapy due to grade 3-4 toxicity. Toxicity was associated with blood concentrations of VNR ≥ 1.57 ng/mL and dVNR ≥ 3.04 ng/mL, but not with MDR1 polymorphisms. CONCLUSIONS: Neither pharmacokinetic nor pharmacogenetic monitoring seem useful to predict OS. On the other hand, high VNR and dVNR blood levels were associated with severe toxicity.

BACKGROUND: There is evidence that cytoreductive nephrectomy (CN) may be beneficial in metastatic renal cell carcinoma (mRCC). This has been studied predominantly in clear-cell RCC, with more limited data on the role of CN in patients with papillary histology. OBJECTIVE: To determine the benefit of CN in synchronous metastatic papillary RCC. DESIGN, SETTING, AND PARTICIPANTS: Using the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) database, a retrospective analysis was performed for patients with papillary mRCC treated with or without CN. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Median overall survival (OS) and progression-free survival (PFS) were determined for both patient groups. Cox regression analysis was performed to control for imbalances in individual IMDC risk factors. RESULTS AND LIMITATIONS: In total, 647 patients with papillary mRCC were identified, of whom 353 had synchronous metastatic disease. Of these, 109 patients were treated with CN and 244 were not. The median follow-up was 57.1mo (95% confidence interval [CI] 32.9-77.8) and the OS from the start of first-line targeted therapy for the entire cohort was 13.2mo (95% CI 12.0-16.1). Median OS for patients with CN was 16.3mo, compared to 8.6mo (p<0.0001) in the no-CN group. When adjusted for individual IMDC risk factors, the hazard ratio (HR) of death for CN was 0.62 (95% CI 0.45-0.85; p=0.0031). Limitations include the retrospective nature of the analysis. CONCLUSIONS: The use of CN in patients with mRCC and papillary histology appears to be associated with better survival compared to no CN after adjustment for risk criteria. Selection of appropriate candidates for CN is crucial. A clinical trial in this rare population may not be possible. PATIENT SUMMARY: In a population of patients with advanced papillary kidney cancer, we found that surgical removal of the primary kidney tumor was associated with better overall survival.

BACKGROUND: Oral vinorelbine administered at the maximum tolerated dose has already showed activity and a good safety profile in advanced non-small-cell lung cancer (NSCLC). The MA.NI.LA study was a phase II, multicenter, randomized, controlled trial that aimed to assess the effects of a 'switched maintenance' regimen with oral metronomic vinorelbine (OMV) in patients with NSCLC who had not progressed after first-line platinum-based chemotherapy. PATIENTS AND METHODS: Patients were randomly assigned in a 1:1 ratio to either OMV (50 mg three-times weekly) as maintenance treatment or best supportive care (BSC). The primary endpoint was progression-free survival (PFS). Secondary endpoints included overall survival (OS), objective disease control rate (DCR, CR + PR + SD), safety and quality of life. RESULTS: In total, 61 and 59 patients were assigned to OMV and BSC, respectively. At a median follow-up of 23.9 (IQR 10.2-38.2) months, patients treated with OMV reported a significantly lower progression rate compared to patient in the BSC arm (89% [54/61] vs 96% [56/58]; HR 0.73; 90% CI 0.53-0.999, p = 0.049). Median PFS for patients treated with vinorelbine was 4.3 months (95% CI 2.8-5.6) vs 2.8 months (95% CI 1.9-4.5) for patients receiving BSC. This benefit was specifically evident in patients aged ≥70 years, in current smokers, and in those who reported disease stabilization as best response to induction chemotherapy. OS and response rate and quality of life were similar in the two arms. Drop-out rate for major toxicity with OMV was unexpectedly high (25%, 14/61) mainly due to grade 3-4 neutropenia (11%, 7/61). Conclusions In patients with unselected NSCLC achieving disease control after platinum-based chemotherapy switch maintenance therapy with OMV prolonged PFS compared to BSC; however, the optimal dose of OMV requires further investigation.

BACKGROUND: The International mRCC (metastatic renal cell carcinoma) Database Consortium (IMDC) is the standard classification for mRCC. We aimed to evaluate the outcomes of a large cohort of patients with an intermediate or a poor prognosis treated with sunitinib using a different cutoff point for IMDC to improve the classification. PATIENTS AND METHODS: Patients with an intermediate or a poor prognosis according to the IMDC criteria and treated with sunitinib were included in the present study. A new cutoff point was used to categorize the patients. The new score was validated in an independent cohort of patients. RESULTS: A total of 457 patients were included in the present study. Significant differences in overall survival (OS) were highlighted regarding the number of prognostic factors. Three categories were identified according to the presence of 1 (ie, favorable-intermediate group), 2 (ie, real-intermediate group), and > 2 (ie, poor group) factors. The corresponding median OS periods were 32.9, 20.0, and 8.9 months, with significant differences among the groups. The validation cohort included 389 patients. The median OS period for the favorable-intermediate group, real-intermediate group, and poor group was 34.3, 19.4, and 9.0 months, respectively, with confirmed significant differences among the groups. CONCLUSION: Our analysis revealed significant differences among patients with an intermediate prognosis using the IMDC prognostic factors. Further investigations to optimize the use of available and upcoming therapies are required.

PURPOSE: Lung cancer is one of the leading causes of cancer-related death worldwide and, although targeted therapy with tyrosine kinase inhibitors has dramatically improved the rates of response and survival in advanced EGFR-mutated adenocarcinoma, the overall outcome remains unsatisfactory. Therefore, new prognostic factors, preferably simple, inexpensive, and easy to reproduce on a large scale, are needed. We performed a retrospective analysis of our database including 63 western Caucasian patients with advanced EGFR-mutated lung adenocarcinoma and receiving gefitinib, erlotinib, or afatinib as first- or second-line therapy. Several studies demonstrated a strong link between elevated neutrophil-to-lymphocyte ratio (NLR) and poor prognosis both in early and advanced stages of non-small-cell lung cancer (NSCLC). METHODS: From January 2011 to December 2015, 63 consecutive elegible patients with advanced EGFR-mutated NSCLC were included in this analysis from 5 institutions. The NLR was derived from the absolute neutrophil and the absolute lymphocyte counts of a full blood count and the cutoff value was determined according to the mean NLR level. RESULTS: Despite the small sample analyzed, we found that NLR has a prognostic role for progression-free survival (PFS) and overall survival (OS), reaching a statistically significant difference with a better PFS and OS in the lower NLR group. CONCLUSIONS: Pretreatment NLR seems to represent a reliable, simple, and easy to reproduce laboratory tool to predict outcome and response to cancer therapies in this setting of Western Caucasian patients with EGFR-mutated NSCLC.

INTRODUCTION: Pazopanib is a standard first-line treatment for metastatic clear-cell renal cell carcinoma (ccRCC). Very few data on its activity in non-clear-cell renal cell carcinoma (nccRCC) are currently available. The aim of this study was to retrospectively analyze efficacy and toxicity of pazopanib in nccRCC patients. PATIENTS AND METHODS: Records from advanced nccRCC patients (consecutive sample) treated with first-line pazopanib between 2010 and 2015 at 17 Italian centers were reviewed. Response rate, progression-free survival (PFS), and overall survival (OS) were evaluated. Univariate and descriptive analyses were performed. RESULTS: Thirty-seven patients with nccRCC were treated with first-line pazopanib; 51% had papillary histology, 24% chromophobe, 22% unclassified, and 3% had Xp11.2 translocation. Dose reductions/temporary interruptions for toxicity were required in 46% of cases. Grade (G) 3/4 toxicity was seen in 32%, G1/2 in 89% of cases; 81% achieved disease control, with 10 partial responses (27%) and 20 cases of stable disease (54%); 16% of patients had disease progression as best response. Median PFS and OS were 15.9 and 17.3 months, respectively. In univariate analysis, nephrectomy (P = .020), Memorial Sloan Kettering Cancer Center (MSKCC) score (P < .001), basal neutrophil/lymphocyte ratio (NLR; P = .009) and performance status (PS) (P = .001) were associated with PFS; MSKCC score (P < .001), International Metastatic Renal Cell Carcinoma Database Consortium score (P = .003), PS (P < .0001), nephrectomy (P = .002), histology (P = .035), dose reductions/interruptions (P = .039), best response to treatment (P < .001), and NLR (P = .008) were associated with OS. CONCLUSION: In nccRCC patients, treatment with pazopanib was effective and feasible; dose reductions required for toxicity were similar as expected in ccRCC.

Outcomes of metastatic papillary renal cell carcinoma (pRCC) patients are poorly characterized in the era of targeted therapy. A total of 5474 patients with metastatic renal cell carcinoma (mRCC) in the International mRCC Database Consortium (IMDC) were retrospectively analyzed. Outcomes were compared between clear cell (ccRCC; n = 5008) and papillary patients (n = 466), and recorded type I and type II papillary patients (n = 30 and n = 165, respectively). Overall survival (OS), progression-free survival (PFS), and overall response rate (ORR) favored ccRCC over pRCC. OS was 8 months longer in ccRCC patients and the hazard ratio of death was 0.71 for ccRCC patients. No differences in PFS or ORR were detected between type I and II PRCC in this limited dataset. The median OS for type I pRCC was 20.0 months while the median OS for type II was 12.6 months (P = 0.096). The IMDC prognostic model was able to stratify pRCC patients into favorable risk (OS = 34.1 months), intermediate risk (OS = 17.0 months), and poor-risk groups (OS = 6.0 months). pRCC patient outcomes were inferior to ccRCC, even after controlling for IMDC prognostic factors. The IMDC prognostic model was able to effectively stratify pRCC patients.

Background: Treatment outcomes are poorly characterized in patients with metastatic chromophobe renal cell cancer (chrRCC), a subtype of renal cell carcinoma. Objective: This retrospective series aims to determine metastatic chrRCC treatment outcomes in the targeted therapy era. Methods: A retrospective data analysis was performed using the IMDC dataset of 4970 patients to determine metastatic chrRCC treatment outcomes in the targeted therapy era. Results: 109/4970 (2.2%) patients had metastatic chrRCC out of all patients with mRCC treated with targeted therapy. These patients were compared with 4861/4970 (97.8%) clear cell mRCC (ccRCC) patients. Patients with metastatic chrRCC had a similar OS compared to patients with ccRCC (23.8 months (95% CI 16.7 - 28.1) vs 22.4 months (95% CI 21.4 - 23.4), respectively (pâ=â0.0908). Patients with IMDC favorable (18%), intermediate (59%) and poor risk (23%) had median overall survivals of 31.4, 27.3, and 4.8 months, respectively (pâ=â0.028). Conclusions: To the authors' knowledge, this is the largest series of metastatic chrRCC patients and these results set new benchmarks for survival in clinical trial design and patient counseling. The IMDC criteria risk categories seem to stratify patients into appropriate favourable, intermediate, and poor risk groups, although larger patient numbers are required. It appears that outcomes between metastatic chrRCC and ccRCC are similar when treated with conventional targeted therapies. Patients with metastatic chrRCC can be treated with tyrosine kinase inhibitors and enrolled in clinical trials to further measure outcomes in this rare patient population.
RESUMEN
AIMS AND BACKGROUND: To identify the maximum tolerated doses and to define the activity of a regimen incorporating leucovorin (LV)-modulated 5-fluorouracil (5-FU) bolus and continuous infusion, oxaliplatin (I-OHP) and irinotecan (CPT-11) in patients with advanced, 5-FU-refractory colorectal cancer (CRC). PATIENTS AND METHODS: Starting doses: LV 100 mg/m2 as a 2-hour infusion followed by 5-FU 300 mg/m2 bolus administration followed by 5-FU 500 mg/m2 as a 22-hour infusion on days 1 and 2; I-OHP 65 mg/m2 as a 2-hour infusion concomitantly with LV on day 1; CPT-11 90 mg/m2 concomitantly with LV on day 2. Planned cycle interval: 2 weeks. RESULTS: Two hundred twenty-six cycles were administered to 27 patients. Recommended doses were 5-FU bolus 300 mg/m2, 5-FU protracted infusion 500 mg/m2, I-OHP 75 mg/m2, and CPT-11 150 mg/m2. Among 25 patients evaluable for response we observed 13 disease stabilizations (52%; 95% CI: 33-71%), 6 instances of disease progression and 6 responses (24%; 95% CI: 7-41%). Median time to progression and overall survival were 24 and 60 weeks, respectively. A cycle delay > 3 days was observed in 134/199 cycles (67%). CONCLUSIONS: This study confirms the feasibility of triplet chemotherapy in patients with advanced 5-FU-refractory CRC.

BACKGROUND: The administration of carboplatin AUC 7 has become a standard adjuvant option for patients undergoing orchiectomy for stage I seminoma, in alternative to radiotherapy on retroperitoneal lymphnodes or surveillance. The toxicity of AUC 7 carboplatin appeared manageable in the pivotal trial of Oliver et al, but dose ranges were not reported. Fear of toxicity may induce arbitrary dose reductions, which may potentially compromise patients' outcome. PATIENTS AND METHODS: We reviewed adjuvant carboplatin administration in 115 stage I seminoma patients followed in 11 Italian medical oncology centers since 2005. Clinical and pathological data, modality of carboplatin dose calculation, dose reductions, toxicities, and relapses were recorded. RESULTS: Median age was 35 years (range, 18-65 years), adverse prognostic factors were either T ≥ 4 cm (17.4%) or rete testis invasion (28.7%), both of them (35.7%), none or unspecified (18.3%). GFR was estimated mainly by Cockroft-Gault formula (55.7%) or Jeliffe formula (26.1%), with a median of 105 mL/min (range, 75-209 mL/min). The median dose of carboplatin was 900 mg (range, 690-1535 mg). A dose reduction > 10% was applied to 14 patients. Toxicities were mild fatigue, moderate nausea/vomiting, 5.2% of grade 3 to 4 thrombocytopenia. After a median follow-up of 22.1 months, 5.2% of patients have relapsed in the retroperitoneal lymph nodes. None of the patients that relapsed were treated with reduced dose. All but one achieved complete remission with salvage chemotherapy. CONCLUSIONS: Adjuvant AUC 7 carboplatin reduce relapses of stage I seminoma patients to 5.2%, with manageable toxicities. Dose reductions should be proscribed.

UNLABELLED: Metastatic castration-resistant prostate cancer mainly affects older men, opening issues about the efficacy and safety of therapies in this population. We have demonstrated that abiraterone, a selective androgen biosynthesis inhibitor, is a safe and active therapeutic option in a subgroup of 47 very elderly adults (aged > 80 years) enrolled in the Italian named patient program, with a tolerability profile and clinical outcomes comparable to those of younger population. BACKGROUND: Prostate cancer mainly affects elderly men, who are often frail and whose reduced physiological reserves and multiple comorbidities increase the risk of side effects. The availability of new drugs has improved the overall survival (OS) of patients with castration-resistant prostate cancer (CRPC) but has increased the number of very elderly CRPC patients receiving anticancer drugs, raising questions about their efficacy and safety in this population. PATIENTS AND METHODS: We assessed the tolerability of abiraterone (AA) in a cohort of very elderly adults with metastatic CRPC (mCRPC) enrolled in the Italian AA named patient program and analyzed their clinical outcomes. We retrospectively reviewed the clinical records of 47 mCRPC patients aged > 80 years who had received AA after docetaxel. The Kaplan-Meier method was used to calculate OS and progression-free survival (PFS). Safety and clinical outcomes were also analyzed by age group (< 80 and > 80 years). Cox regression analysis was used to calculate the differences in PFS and OS between the groups according to the stratification variables. RESULTS: In very elderly men, the prostate-specific antigen response rate was 48.9%, and the median PFS and OS were 8 and 18 months, respectively. The differences in toxicities between the older and younger age groups were not major. The limitation of the present study was mainly its retrospective nature. CONCLUSION: Our data show that AA is active and safe in very elderly patients and leads to outcomes similar to those observed in younger patients, thus confirming that AA is a manageable therapeutic option for this patient population.
