RESUMO
BACKGROUND: This study was designed to demonstrate the non-inferiority (NI) in overall survival (OS) of suspension of androgen deprivation therapy (ADT) versus maintenance and intermittent versus continuous docetaxel administration in metastatic castration-resistant prostate cancer (mCRPC) patients. PATIENTS AND METHODS: mCRPC patients were randomised to first-line docetaxel with maintenance or suspension of ADT. Patients attaining a prostate-specific antigen (PSA) response after four chemotherapy cycles underwent second randomisation to receive continuous or intermittent docetaxel therapy. Six hundred patients were to be randomised to achieve 80% statistical power to demonstrate an NI hazard ratio (HR) of 1.25 of interruption versus maintenance of ADT. RESULTS: The trial was prematurely closed when 198 participants were randomised. OS was similar in patients who continued (N = 96) versus those who interrupted (n = 102) ADT during docetaxel therapy (HR 0.98, 95% confidence interval [CI] 0.72-1.33] and those on a continuous (N = 35) versus an intermittent (N = 42) docetaxel schedule (HR 0.86, 95% CI 0.55-1.43). No difference in radiological progression-free survival, PSA response, or toxicity was observed between the study arms. The actual NI hazard margins of OS in Arms A and B patients were 1.33 and 1.43, respectively. CONCLUSIONS: This trial enrolled one-third of the planned patients; this main weakness dramatically limits the interpretation of the results. ADT discontinuation and switching to an intermittent schedule did not seem to affect docetaxel efficacy. The absence of testosterone recovery in the majority of patients could have been a contributory factor. In men with mCRPC, ADT discontinuation should only be done with regular biochemical and clinical monitoring, with the option of quickly restarting ADT at disease progression.

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.

AIMS AND OBJECTIVES: To assess the effectiveness of a specific home care nursing programme in addition to standard care in patients (pts) receiving oral anticancer treatments. BACKGROUND: Oral anticancer therapy present challenges for pts since treatment is a home-based therapy. This study evaluates the potentiality of a home care nursing programme in decreasing hospital accesses for not severe toxicity. METHODS: This is an open-label, multicentre, randomised trial including pts who were receiving an anticancer oral drug. The study complies with the CONSORT checklist published in 2010. Concomitant use of radiation therapy, intravenous or metronomic therapies, or the intake of previous oral drugs was not allowed. Pts were randomly assigned to home care nursing programme (A) or standard care (B). In arm A, dedicated nurses provided information to pts, a daily record on which pts would take note of drugs and dosages and a telephone monitoring during the first two cycles of therapy. The primary outcome was the reduction in improper hospital accesses for grade 1-2 toxicity according to CTCAE v4.0. RESULTS: Out of 432 randomised pts, 378 were analysed (184 pts in arm A and 194 in arm B). Hospital accesses were observed in 41 pts in arm A and in 42 pts in arm B (22.3% vs. 21.6%, respectively). No difference was detected in proportion of improper accesses between arm A and arm B (29.3% vs. 23.8%, respectively). CONCLUSIONS: Our experience failed to support the role of a specific home care nursing programme for pts taking oral chemotherapy. An improved attention to specific educational practice and information offered to pts can explain these results. RELEVANCE TO CLINICAL PRACTICE: Our results underline the role of nurse educational practice and information offered to patients. A careful nurse information of patients about drugs is essential to reduce toxicities avoiding the opportunity of a specific home monitoring.

BACKGROUND: Cervical cancer cells often express Epidermal Growth Factor Receptor (EGFR). Cetuximab (CET), an anti-EGFR antibody, can be safely combined with carboplatin (C) and paclitaxel (P), a standard treatment for advanced/recurrent cervical cancer (ARCC) patients. PATIENTS AND METHODS: ARCC patients, ECOG PSâ¯≤â¯1, were randomized to CP for 6â¯cycles with or without CET (400â¯mg/m2 one week before starting CP, then 250â¯mg/m2 weekly) until disease progression or unacceptable toxicity. Event-free survival (EFS) was the primary endpoint. With a 4.5â¯months expected median EFS and a 6.4â¯months predicted EFS (HR 0.70), 0.20 one-tailed α and 80% power, 89 events were required for the final intent-to-treat analysis. RESULTS: 108 patients were assigned to CP (nâ¯=â¯53) or CP-CET (nâ¯=â¯55). Median age was 50, 69% were PS0, 76% had recurrent disease, 91% had distant metastasis and 57% had received previous chemotherapy. After a median follow-up of 23â¯months, 102 patients had an event, 97 progressed and 61 died. Median EFS was 4.7 and 6.0â¯months (one-tail Pâ¯=â¯0.43), median PFS was 5.2 and 7.6â¯months (one-tail Pâ¯=â¯0.20) and median OS was 17.7 and 17â¯months (one-tail Pâ¯=â¯0.27), with CP and CP-CET, respectively. There was no difference in the occurrence of severe adverse events, except for skin toxicity. Biomarker analysis, in a small subgroup of patients, suggests that PIK3CA mutation might be predictive of CET resistance. CONCLUSION: CP-CET was not more active than CP alone in unselected ARCC patients.

BACKGROUND: No compelling evidence is available about surveillance and follow-up of patients with testicular germ cell tumour (TGCT). METHODS: In the light of the best clinical evidence, the Italian Germ cell cancer Group (IGG) and the Associazione Italiana di Oncologia Medica (AIOM) set up a multidisciplinary national consensus conference, involving 42 leading experts and 3 TGCT survivors. A minimum of 50% of votes was required in order to achieve a consensus recommendation on 29 questions. RESULTS: Recommendations have been summarized in three tables, divided by stage I seminoma, stage I nonseminoma and the advanced disease, which may be useful for clinicians to appropriately choose the clinical investigation and its timing during the surveillance and follow-up of TGCT patients based on an accurate estimation of their risk of disease relapse. CONCLUSIONS: The IGG-AIOM consensus recommendations may help clinicians to choose appropriate clinical investigations for the surveillance and follow-up of TGCT patients.

Prognostic characterization in the initial assessment of patients with advanced cancer disease is an essential step to plan the most appropriate therapeutic program. Since clinical prediction of survival (CPS) may be of limited value, some authors have tried to integrate specific prognostic factors into prognostic multidimensional scores. We carried out a prospective cohort study in two palliative care units to compare the accuracy of the Palliative Prognostic (PaP) Score, the Objective Prognostic Score (OPS), and the Palliative Prognostic Index (PPI). In addition, we compared the accuracy of the CPS independently estimated by different healthcare professionals and we tested the role of laboratory results, together with clinical and social factors in predicting survival. Clinical and laboratory data of 334 advanced cancer patients were prospectively collected from the time of in-hospital admission. PaP Score was the most accurate index of survival prediction, followed by PPI; CPS estimates' accuracy was similar among physicians and nurse. All healthcare professionals tended to underestimate the real survival. Integrating CPS with multidimensional indexes may further improve the patient's management. The degree of autonomy and the number of metastatic sites were independent prognostic factors for 30-days mortality and overall survival in multivariate analysis.

AIM: We report the outcomes observed with nivolumab in metastatic renal cell carcinoma patients with poor prognostic features enrolled in the Italian expanded access program. PATIENTS & METHODS: Nivolumab was available for patients who relapsed after at least one prior systemic treatment in the advanced or metastatic setting. RESULTS: Of 389 patients, 32 (8%) had brain metastasis, 129 (33%) had liver and 193 (50%) had bone metastasis. These subpopulations achieved a disease control rate of 53, 45 and 47%, respectively. Fifty-one patients had G4 tumor, and they showed 23% objective response rate. The safety profile of the subgroups was in line with the expanded access program population. No new safety signals were reported. CONCLUSION: Patients with poor prognostic features may derive relevant benefits from nivolumab.

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 Platinum-based chemotherapy (PBC) for patients with progressing ovarian cancer (OC) is more effective with a longer time interval from previous platinum treatment (platinum-free interval [PFI]). In 1999, it was hypothesized that prolonging PFI with single-agent non-PBC (NPBC) may offer a strategy to improve overall outcome. MITO-8 aimed to verify this hypothesis commonly used in clinical practice although it has not been prospectively tested. Methods MITO-8 is an open-label, prospective, randomized, superiority trial. Patients with OC who experienced disease progression 6 to 12 months after their last platinum treatment were randomly assigned 1:1 to the experimental sequence of NPBC followed by PBC at subsequent relapse or the standard reverse treatment sequence. Overall survival (OS) was the primary end point. Results Two hundred fifteen patients were enrolled (standard arm [n = 108]; experimental arm [n = 107]). The trial ended before planned because of slow enrollment. PFI was prolonged in the experimental arm (median, 7.8 v 0.01 months). There was no OS benefit in the experimental arm (median, 21.8 v 24.5 months; hazard ratio, 1.38; 95% CI, 0.99 to 1.94; P = .06). Progression-free survival after the sequence was significantly shorter in the experimental arm (median, 12.8 v 16.4 months; hazard ratio, 1.41; 95% CI, 1.04 to 1.92; P = .025). Global quality-of-life change after three cycles was worse in the experimental arm. Slight differences were observed in the incidence of adverse effects. Conclusion MITO-8 supports the recommendation that PBC not be delayed in favor of an NPBC in patients with partially platinum-sensitive OC. PBC should be used as a control arm in future trials of new drugs in this setting.

One of the priorities of personalized medicine regards the role of early integration of palliative care with cancer-directed treatments, called simultaneous care. This article, written by the Italian Association of Medical Oncology (AIOM) Simultaneous and Continuous Care Task Force, represents the position of Italian medical oncologists about simultaneous care, and is the result of a 2-step project: a Web-based survey among medical oncologists and a consensus conference. We present the opinion of more than 600 oncologists who helped formulate these recommendations. This document covers 4 main aspects of simultaneous care: 1) ethical, cultural, and relational aspects of cancer and implications for patient communication; 2) training of medical oncologists in palliative medicine; 3) research on the integration between cancer treatments and palliative care; and 4) organizational and management models for the realization of simultaneous care. The resulting recommendations highlight the role of skills and competence in palliative care along with implementation of adequate organizational models to accomplish simultaneous care, which is considered a high priority of AIOM in order to grant the best quality of life for cancer patients and their families.

BACKGROUND: Early integration of palliative care in oncology practice ("simultaneous care", SC) has been shown to provide better care resulting in improved quality-of-life and also survival. We evaluated the opinions of Italian Association of Medical Oncology (AIOM) members. PATIENTS AND METHODS: A 37-item questionnaire was delivered to 1119 AIOM members. Main areas covered were: social, ethical, relational aspects of disease and communication, training, research, organizational and management models in SC. Three open questions explored the definition of Quality of Life, Medical Oncologist and Palliative Care. RESULTS: Four hundred and forty-nine (40.1%) medical oncologists returned the questionnaires. Forty-nine percent stated they address non-curability when giving a diagnosis of metastatic tumor, and 43% give the information only to patients who clearly ask for it. Fifty-five percent say the main formative activity in palliative medicine came from attending meetings and 90% agree that specific palliative care training should be part of the core curriculum in oncology. Twenty-two percent stated they consulted guidelines for symptom management, 45% relied upon personal experience and 26% make a referral to a palliative care specialist. Seventy-four percent were in favor of more research in palliative medicine. An integration between Units of Oncology and Palliative Care Services early in the course of advanced disease was advocated by 86%. Diverse and multifaceted definitions were given for the concepts of Quality of Life, Palliative Care and Medical Oncologist. CONCLUSION: SC is felt as an important task, as well as training of medical oncologists in symptom management and research in this field.
RESUMO
AIMS: The intermittent administration of chemotherapy is a means of preserving patients' quality of life (QL). The aim of this study was to verify whether the intermittent administration of docetaxel (DOC) improves the patients' QL. PATIENTS & METHODS: All patients received DOC 70 mg/m(2) every 3 weeks for eight cycles. The patients were randomized to receive DOC continuously or with a fixed 3-month interval after the first four DOC courses. RESULTS: The study involved 148 patients. There was no difference in QL between the groups receiving intermittent or continuous treatment. Intermittence had no detrimental effects on disease control. CONCLUSION: Although feasible and not detrimental, our results showed that true intermittent chemotherapy in metastatic castration-resistant prostate cancer patients failed to improve the patients' QL.

PURPOSE: Several prognostic models have been proposed for metastatic renal cell carcinoma but none has been validated in patients who receive third line targeted agents. We evaluated prognostic factors in patients with metastatic renal cell carcinoma who received a third line targeted agent. MATERIALS AND METHODS: We retrospectively reviewed data on 2,065 patients with clear cell metastatic renal cell carcinoma who were treated with targeted therapy at a total of 23 centers in Italy. Included in final analysis were 281 patients treated with 3 targeted agents. Overall survival was the main outcome. Cox proportional hazards regression followed by bootstrap validation was used to identify independent prognostic factors. RESULTS: Three clinical characteristics (ECOG performance status greater than 1, metastasis at diagnosis and liver metastasis) and 2 biochemical factors (hemoglobin less than the lower limit of normal and neutrophil count greater than the upper limit of normal, respectively) were prognostic. Patients were classified into 3 risk categories, including low-zero or 1, intermediate-2 and high risk-more than 2 risk factors. Median overall survival was 19.7, 10.1 and 5.5 months, and 1-year overall survival was 71%, 43% and 15%, respectively. The major limitation was the retrospective nature of this study and absent external validation. CONCLUSIONS: This nomogram included clinical and biochemical prognostic factors. In clinical trials it may be useful to select patients and define the prognosis.

BACKGROUND AND AIMS: Ovarian clear cell carcinoma (CCC) has a poorer prognosis than other subtypes of ovarian cancer. In this study, we evaluated the responsiveness to second-line chemotherapy in recurrent ovarian CCC. METHODS: The MITO-9 project investigated a cohort of patients observed between 1991 and 2007 in 20 centers. We identified 72 out of 240 patients with recurrent disease (28% stage I-II and 72% stage III-IV at diagnosis). RESULTS: In 56% of patients, the clear cell histology was pure. Twenty-five patients were platinum-resistant, 18 were platinum-sensitive with a platinum-free interval (PFI) of 6-12 months, and 29 had a PFI >12 months. Upon recurrence, 47% of patients were treated with platinum chemotherapy according to the PFI. The overall response rate (RR) to platinum was 80%, with 55, 100, and 80% RR in patients with PFI of 6-12, >12, and >24 months. The RR to nonplatinum agents in resistant patients was 33%. Among the nonplatinum agents used in primary and secondary resistant cases, gemcitabine, administered in 12 cases, had a higher activity (RR = 66%) compared to topotecan or liposomal doxorubicin (n = 31; RR = 33 and 10%, respectively). CONCLUSIONS: This study showed that the treatment of recurrent ovarian CCC should be based on the PFI as in the other subtypes. Data in platinum-resistant patients suggest gemcitabine as the drug with the highest activity. We recommend that gemcitabine be studied prospectively in a phase 2 trial.

BACKGROUND: Carboplatin plus paclitaxel administered every 3 weeks is standard first-line chemotherapy for patients with advanced ovarian cancer. A weekly paclitaxel schedule combined with carboplatin every 3 weeks prolonged progression-free survival and overall survival in a Japanese phase 3 trial. The aim of our study was to assess whether a weekly schedule of carboplatin plus paclitaxel is more effective than the same drugs given every 3 weeks. METHODS: We did a multicentre, randomised, phase 3 study at 67 institutions in Italy and France. Women with FIGO stage IC-IV ovarian cancer, an ECOG performance status of 2 or lower, and who had never received chemotherapy were randomly allocated in a 1:1 ratio to receive either carboplatin (AUC 6 mg/mL per min) plus paclitaxel (175 mg/m(2)) every 3 weeks for six cycles or carboplatin (AUC 2 mg/mL per min) plus paclitaxel (60 mg/m(2)) every week for 18 weeks. Randomisation was done by computer-based minimisation, stratified by centre, residual disease after surgery, and ECOG performance status. The study was not blinded. Coprimary endpoints were progression-free survival and quality of life (assessed by the Functional Assessment of Cancer Therapy Ovarian Trial Outcome Index [FACT-O/TOI] score), and analysis was by modified intention to treat. This report presents the final analysis. The study is registered with ClinicalTrials.gov, number NCT00660842. FINDINGS: 822 patients were enrolled into the study between Nov 20, 2008, and March 1, 2012; 12 withdrew their consent immediately after randomisation and were excluded, and 810 were eligible for analysis. 404 women were allocated treatment every 3 weeks and 406 were assigned to the weekly schedule. After median follow-up of 22·3 months (IQR 16·2-30·9), 449 progression-free survival events were recorded. Median progression-free survival was 17·3 months (95% CI 15·2-20·2) in patients assigned to treatment every 3 weeks, versus 18·3 months (16·8-20·9) in women allocated to the weekly schedule (hazard ratio 0·96, 95% CI 0·80-1·16; p=0·66). FACT-O/TOI scores differed significantly between the two schedules (treatment-by-time interaction p<0·0001); with treatment every 3 weeks, FACT-O/TOI scores worsened at every cycle (weeks 1, 4, and 7), whereas for the weekly schedule, after transient worsening at week 1, FACT-O/TOI scores remained stable. Fewer patients assigned to the weekly group than those allocated treatment every 3 weeks had grade 3-4 neutropenia (167 [42%] of 399 patients vs 200 [50%] of 400 patients), febrile neutropenia (two [0·5%] vs 11 [3%]), grade 3-4 thrombocytopenia (four [1%] vs 27 [7%]), and grade 2 or worse neuropathy (24 [6%] vs 68 [17%]). Three deaths during the study were attributed to chemotherapy; two women died who were allocated treatment every 3 weeks and one death was recorded in the group assigned the weekly regimen. INTERPRETATION: A weekly regimen of carboplatin and paclitaxel might be a reasonable option for first-line treatment of women with advanced ovarian cancer. FUNDING: None.

OBJECTIVES: To correlate the expression profile of human apurinic endonuclease/redox factor 1 (APE1/Ref-1) with that of nucleolar/nucleoplasmic protein nucleophosmin 1 (NPM1) in association with the aggressiveness and progression of high-grade ovarian serous cancer. METHODS: Retrospective study analyzing a tissue microarray of 73 women affected by high-grade ovarian serous cancer. Protein expression was assessed by immunohistochemistry on primary tumor masses and synchronous peritoneal metastases if present. RESULTS: APE1/Ref-1 and NPM1 showed a significant correlation in ovarian serous cancer. Patients with a poorer outcome showed a significant overexpression of nuclear NPM1 protein. A Cox proportional hazards multivariate regression model revealed NPM1 expression to be independently significant for overall survival in high-grade ovarian serous cancers after correcting for stage, age, cytoreduction completeness, and platinum resistance. CONCLUSIONS: APE1/Ref-1 interacts with NPM1 to control the DNA damage repair system, and it is likely that this interaction plays a defining role in high-grade ovarian serous carcinoma. A high NPM1 immunohistochemical expression was independently correlated with a shorter survival period and thus appears to be an important prognostic factor.

BACKGROUND: There are no data on the patterns of care and outcome of elderly patients with mRCC treated with sunitinib. In a retrospective study, we assessed the routine use of first-line sunitinib in mRCC patients aged ≥ 70 years. PATIENTS AND METHODS: We reviewed the clinical files of 185 patients aged ≥ 70 years with mRCC treated with first-line sunitinib in 17 Italian oncology units from February 2006 to September 2011. One hundred twenty-three patients (66.5%) received a standard 50 mg/d for a 4 weeks on/2 weeks off regimen (SR), and 62 patients (33.5%) received an AR consisting of 37.5 mg/d for a 4 weeks on/2 weeks off in 67.7% of cases. RESULTS: Median age was 74 years. Patients treated with an AR were older than those treated with the SR (P < .0001). In the overall population, the median progression-free survival (PFS) was 11 months, and the median overall survival (OS) was 25.5 months. Grade 3-4 toxicities occurred in 87 of 123 SR (70.7%) and 32 of 62 AR (51.6%), respectively; dose reductions were required in 82 SR (66.7%) and 26 AR (41.9%), respectively; discontinuations because of therapy-related adverse events occurred in 25 SR (20.3%) and 15 AR (24.2%), respectively. In multivariate analysis, only performance status and the Heng score were predictors of either PFS or OS. CONCLUSION: Sunitinib is active and feasible in elderly patients with mRCC. A sunitinib AR could be considered as an option in selected older mRCC patients. The optimal treatment of frail patients with mRCC remains to be established.

AIM: A number of targeted therapies (TTs) are effective in metastatic renal cell carcinoma (mRCC) but clinical outcomes with the sequential use of three TTs have been poorly investigated, this study evaluates their outcome. METHODS: Patients with clear cells mRCC treated with three TTs were retrospectively studied. Therapies were classified as vascular endothelial growth factor (VEGF)/vascular endothelial growth factor receptor (VEGFR) or mammalian target of rapamycin inhibitors (mTORi). Progression free survival (PFS), overall survival (OS) and total PFS (tPFS)--defined as the time from start of first-line to progression on third-line treatment--were estimated using the Kaplan-Meier method and curves were compared with log-rank test. RESULTS: A total of 2065 patients with mRCC were consecutively treated with first-line TT in 23 centres in Italy. Overall 281/2065 patients (13%) were treated with three TTs. Median OS and tPFS were 44.7 and 34.1 months, respectively and were longer in patients receiving the sequence vascular endothelial growth factor inhibitors (VEGFi)-VEGFi-mTORi compared with those receiving VEGFi-mTORi-VEGFi with a statistical difference in OS (50.7 versus 37.8 months, p = 0.004; 36.5 versus 29.3 months, p = 0.059, respectively). CONCLUSIONS: Few patients received three lines of TTs. The sequence VEGFi-VEGFi-mTORi was associated with improved survival with respect to VEGFi-mTORi-VEGFi and primary resistance to first-line was a negative predictive and prognostic factor.
