Introduction: The optimal management of high risk WHO grade II gliomas after surgery is debated including the role of initial temozolomide to delay radiotherapy and risk of cognitive defects., Methods: A post-hoc analysis of a phase II multicenter study on high risk WHO grade II gliomas, receiving initial temozolomide alone, has re-evaluated the long-term results within the molecular subgroups of WHO 2016. The primary endpoint of the study was response according to RANO, being seizure response, PFS and OS secondary endpoints., Results: Response rate among oligodendrogliomas IDH-mutant and 1p/19q codeleted (76%) was significantly higher than that among diffuse astrocytomas either mutant (55%) or wild-type (36%). A reduction of seizure frequency > 50% was observed in 87% of patients and a seizure freedom in 72%. The probability of seizure reduction > 50% was significantly associated with the presence of an IDH mutation. Median PFS, PFS at 5 and 10 years, median OS and OS at 5 and 10 years were significantly longer in oligodendrogliomas IDH-mutant and 1p/19q codeleted. Sixty-seven percent of patients with oligodendroglioma IDH mutant and 1p/19q codeleted did not recur with a median follow up of 9.3 years, while 59% did not receive radiotherapy at recurrence with a median follow up of 8.2 years., Conclusions: The beneficial effects of initial temozolomide prevail in oligodendrogliomas IDH-mutant and 1p/19q codeleted: thus, these tumors, when incompletely resected or progressive after surgery alone, or with intractable seizures, should receive temozolomide as initial treatment with salvage radiotherapy and/o reoperation and/or second-line chemotherapy at recurrence.

Background: Type 2 diabetes mellitus (T2DM) is associated with increased risk of colon cancer (CC), whereas metformin use seems to be protective. However, the impact of metformin use on the risk of death or disease recurrence after radical surgery for CC remains uncertain., Materials and Methods: This is a substudy conducted in patients with high-risk stage II or stage III CC randomized in the TOSCA trial, which compared 3 versus 6 months of fluoropyrimidine-oxaliplatin adjuvant chemotherapy. Objective of the study was to investigate the impact of metformin exposure during adjuvant chemotherapy on overall survival (OS) and relapse-free survival (RFS). We also evaluated the impact of T2DM or metformin dosage on clinical outcomes., Results: Out of 3,759 patients enrolled in the TOSCA trial, 133 patients with diabetes (9.2%) and 1,319 without diabetes (90.8%) were recruited in this study. After excluding 13 patients with diabetes without information on metformin exposure, 76 patients with T2DM (63.3%) were defined as metformin users and 44 (36.7%) as metformin nonusers. After a median follow-up of 60.4 months, 26 (21.7%) patients relapsed and 16 (13.3%) died. Metformin use was neither associated with OS (adjusted hazard ratio [HR], 1.51; 95% confidence interval [CI], 0.48-4.77; p = .4781) nor with RFS (HR, 1.56; 95% CI, 0.69-3.54; p = .2881). Similarly, we found no association between T2DM or metformin dosage and OS or RFS., Conclusions: Metformin use and T2DM did not impact on OS or RFS in patients with resected CC treated with adjuvant fluoropyrimidine-oxaliplatin chemotherapy. Larger studies and longer follow-up are required to clarify the potential efficacy of metformin in improving the prognosis of patients with CC., Implications for Practice: The role of the antidiabetic drug metformin in colon cancer prevention and treatment is highly debated. While low-dose metformin reduced the incidence of colorectal adenomas in two prospective studies, its effect in patients with already established colon cancer remains unclear. In this study, the potential impact of metformin on the survival of resected colon cancer patients who received adjuvant chemotherapy was investigated in the context of the TOSCA study. We did not find any association between metformin use or dosages and patient survival. Prospective studies are required to draw definitive conclusions about metformin impact on colon cancer recurrence and survival., Competing Interests: Disclosures of potential conflicts of interest may be found at the end of this article., (© AlphaMed Press 2019.)

Background: Glioblastoma is a highly vascularised tumour and there are few treatment options after disease recurrence. Regorafenib is an oral multikinase inhibitor of angiogenic, stromal, and oncogenic receptor tyrosine kinases. We aimed to assess the efficacy and safety of regorafenib in the treatment of recurrent glioblastoma., Methods: REGOMA is a randomised, multicentre, open-label phase 2 trial done in ten centres in Italy. Eligible patients (aged ≥18 years) with histologically confirmed glioblastoma, Eastern Cooperative Oncology Group performance status 0 or 1, and documented disease progression after surgery followed by radiotherapy and temozolomide chemoradiotherapy were randomly assigned (1:1) by a web-based system, stratified by centre and surgery at recurrence (yes vs no), to receive regorafenib 160 mg once daily for the first 3 weeks of each 4-week cycle or lomustine 110 mg/m 2 once every 6 weeks until disease progression, death, unacceptable toxicity, or consent withdrawal. The primary endpoint was overall survival in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, NCT02926222, and is currently in follow-up., Findings: Between Nov 27, 2015, and Feb 23, 2017, 124 patients were screened and 119 eligible patients were randomly assigned to receive regorafenib (n=59) or lomustine (n=60). Median follow-up was 15·4 months (IQR 13·8-18·1). At the analysis cutoff date, 99 (83%) of 119 patients had died: 42 (71%) of 59 in the regorafenib group and 57 (95%) of 60 in the lomustine group. Overall survival was significantly improved in the regorafenib group compared with the lomustine group, with a median overall survival of 7·4 months (95% CI 5·8-12·0) in the regorafenib group and 5·6 months (4·7-7·3) in the lomustine group (hazard ratio 0·50, 95% CI 0·33-0·75; log-rank p=0·0009). Grade 3-4 treatment-related adverse events occurred in 33 (56%) of 59 patients treated with regorafenib and 24 (40%) of 60 with lomustine. The most frequent grade 3 or 4 adverse events related to regorafenib were hand-foot skin reaction, increased lipase, and blood bilirubin increased (in six [10%] of 59 patients each). In the lomustine group, the most common grade 3 or 4 adverse events were decreased platelet count (eight [13%] of 60 patients), decreased lymphocyte count (eight [13%]), and neutropenia (seven [12%]). No death was considered by the investigators to be drug related., Interpretation: REGOMA showed an encouraging overall survival benefit of regorafenib in recurrent glioblastoma. This drug might be a new potential treatment for these patients and should be investigated in an adequately powered phase 3 study., Funding: Veneto Institute of Oncology and Bayer Italy., (Copyright © 2019 Elsevier Ltd.

Purpose: Combination of anthracyclines with trastuzumab is hampered by cardiotoxicity. Pegylated liposomal doxorubicin and lapatinib could represent a safer alternative to combination therapy., Methods: In this phase Ib study with 3 + 3 dose escalation design, patients with HER2-positive advanced breast cancer received pegylated liposomal doxorubicin 30 mg/m 2 intravenously on day 1 plus lapatinib 1250 (level 1) or 1500 (level 2) mg/day orally on days 1-21 of each 21-day cycle. The aims were to establish the maximum tolerated dose at first cycle, and the activity and safety of multiple cycles., Results: Nine patients out of 11 enrolled were evaluable: 3 at level 1 and 6 at level 2. No dose-limiting toxicities occurred at dose level 1, while 1 (grade 3 diarrhea) occurred at dose level 2, leading to the expansion of this cohort to 6 patients, with no further dose-limiting toxicities. Main grade 1-2 toxicities at first cycle were leucopenia, diarrhea, elevated transaminases, mucositis. Three patients had grade 3 toxicities at subsequent cycles, including colitis, anorexia, stomatitis plus hand-foot syndrome. One partial response, 5 disease stabilizations, and 3 disease progressions were reported., Conclusions: Combination of pegylated liposomal doxorubicin and lapatinib is feasible and potentially active in pretreated HER2-positive advanced breast cancer patients., Trial Registration: NCT02131506 (ClinicalTrials.gov identifier).

Li-Fraumeni syndrome (LFS) is an autosomal dominant disorder occurring at a young age that predisposes individuals to multiple forms of cancer and to a heterogeneous spectrum of malignancies. We describe the clinical history of a patient who had 5 primary malignant cancers and a familiar history consistent with LFS. We analyzed the genomic DNA of the proband and her relatives by next-generation sequencing (NGS) technology using an enrichment protocol for the simultaneous sequencing of 94 genes involved in hereditary cancers. Genetic analysis of the proband revealed a TP53 germline mutation in exon 5 determining a nucleotide alteration at codon 175 (R175H), a hot spot mutation site related to LFS and a reported pathogenic mutation. The proband daughter's and brother's DNA did not carry the TP53 mutation but they had some rare variants in common with the proband, in addition to other variants with a still unclear role. In conclusion, we identified a TP53 mutation in a patient with multiple primary tumors and a family history characterized by a severe susceptibility to cancer. The genetic analysis by targeted NGS led to the identification of the genetic background and to the exclusion of a cancer risk for the family members. Targeted NGS represents an efficient approach for the identification of mutations in families with a heterogeneous phenotype.

Despite advances in the treatment of glioblastoma (GBM), median survival is 12-15 months. O6-methylguanine-DNA methyltransferase (MGMT) gene promoter methylation status is acknowledged as a predictive marker for temozolomide (TMZ) treatment. When MGMT promoter values fall into a "methylated" range, a better response to chemotherapy is expected. However, a cutoff that discriminates between "methylated" and "unmethylated" status has yet to be defined. We aimed to identify the best cutoff value and to find out whether variability in methylation profiles influences the predictive capacity of MGMT promoter methylation. Data from 105 GBM patients treated between 2008 and 2013 were analyzed. MGMT promoter methylation status was determined by analyzing 10 CpG islands by pyrosequencing. Patients were treated with radiotherapy followed by TMZ. MGMT promoter methylation status was classified into unmethylated 0-9 %, methylated 10-29 % and methylated 30-100 %. Statistical analysis showed that an assumed methylation cutoff of 9 % led to an overestimation of responders. All patients in the 10-29 % methylation group relapsed before the 18-month evaluation. Patients with a methylation status ≥30 % showed a median overall survival of 25.2 months compared to 15.2 months in all other patients, confirming this value as the best methylation cutoff. Despite wide variability among individual profiles, single CpG island analysis did not reveal any correlation between single CpG island methylation values and relapse or death. Specific CpG island methylation status did not influence the predictive value of MGMT. The predictive role of MGMT promoter methylation was maintained only with a cutoff value ≥30 %.

The role of temozolomide concurrent with and adjuvant to radiotherapy (RT/TMZ) in elderly patients with glioblastoma (GBM) remains unclear. We evaluated the outcome of patients >70 years in the context of the Project of Emilia-Romagna Region in Neuro-Oncology (PERNO), the first Italian prospective observational population-based study in neuro-oncology. For this analysis the criteria for selecting patients enrolled in the PERNO study were: age >70 years; PS 0-3; histologically confirmed GBM; postoperative radiotherapy (RT) after surgery with or without concomitant temozolomide (TMZ) or postsurgical TMZ alone. Between January 2009 and December 2010, 76 GBM elderly patients were identified in the prospective PERNO study. Twenty-three patients did not receive any treatment after surgery, and 53 patients received postsurgical treatments (25 patients received RT alone and 28 patients RT/TMZ). Median survival was 11.1 months (95 % CI 8.8-13.5), adding temozolomide concomitant and adjuvant to radiotherapy it was 11.6 months (95 % CI 8.6-14.6), and 9.3 months (95 % CI 8.1-10.6) in patients treated with RT alone (P = 0.164). However, patients with MGMT methylated treated with RT/TMZ obtained a better survival (17.2 months, 95 % CI 11.5-22.9) (P = 0.042). No difference in terms of survival were observed if patients with MGMT unmethylated tumor received RT alone, or RT/TMZ or, in MGMT methylated tumor, if patients received radiotherapy alone. In elderly patients RT/TMZ represent a widely used approach but it is effective with methylated MGMT tumors only.

Background: The efficacy of systemic antineoplastic therapy on recurrent World Health Organization (WHO) grades II and III meningiomas is unclear., Methods: We performed a retrospective multicenter analysis of serial cranial MRI in patients with recurrent WHO II and III meningiomas treated with antineoplastic systemic therapies. Growth rates for tumor volume and diameter, as well as change rates for edema size, were calculated for all lesions., Results: We identified a total of 34 patients (23 atypical, 11 anaplastic meningiomas) with a total of 57 meningioma lesions who had been treated at 6 European institutions. Systemic therapies included bevacizumab, cytotoxic chemotherapy, somatostatin analogues, and tyrosine kinase inhibitors. Overall, tumor growth rates decreased during systemic therapy by 51% for tumor diameter and 14% for tumor volume growth rates compared with the period before initiation of systemic therapy. The most pronounced decrease in meningioma growth rates during systemic therapy was evident in patients treated with bevacizumab, with a reduction of 80% in diameter and 59% in volume growth. Furthermore, a decrease in size of peritumoral edema after initiation of systemic therapy was exclusively observed in patients treated with bevacizumab (-107%)., Conclusions: Our data indicate that systemic therapy may inhibit growth of recurrent WHO grades II and III meningiomas to some extent. In our small cohort, bevacizumab had the most pronounced inhibitory effect on tumor growth, as well as some anti-edematous activity. Prospective studies are needed to better define the role of medical therapies in this tumor type., (© The Author(s) 2015.

Purpose: Hydroxyurea (HU) is among the most widely used salvage therapies in progressive meningiomas. Platelet-derived growth factor receptors are expressed in virtually all meningiomas. Imatinib sensitizes transformed cells to the cytotoxic effects of chemotherapeutic agents that interfere with DNA metabolism. The combination of HU with imatinib yielded intriguing results in recurrent malignant glioma. The current trial addressed the activity of this association against meningioma., Methods: Patients with recurrent or progressive WHO grade I-III meningioma, without therapeutic indication for surgery, radiotherapy, or stereotactic radiosurgery, aged 18-75 years, ECOG performance status 0-2, and not on enzyme-inducing anti-epileptic drugs were randomized to receive HU 500 mg BID ± imatinib 400 mg QD until progression, unacceptable toxicity, or patient's refusal. The primary endpoint was progression-free survival rate at 9 months (PFS-9)., Results: Between September 2009 and February 2012, 15 patients were randomized to receive HU + imatinib (N = 7; Arm A) or HU alone (N = 8; Arm B). Afterward the trial was prematurely closed due to slow enrollment rate. PFS-9 (A/B) was 0/75%, and median PFS was 4/19.5 months. Median and 2-year overall survival (A/B) rates were: 6/27.5 months; 28.5/75%, respectively. Main G3-4 toxicities were: G3 neutropenia in 1/0, G4 headache in 1/1, and G3 vomiting in 1/0., Conclusion: The conduction of a study in recurrent or progressive meningioma remains a challenge. Given the limited number of patients enrolled, no firm conclusions can be drawn about the combination of imatinib and HU. The optimal systemic therapy for meningioma failing surgery and radiation has yet to be identified.

Performing randomised clinical trials to address the clinical usefulness of predictive and prognostic tumour markers is a complex process for several reasons, and observational experiences may thus play an important role. The present study performed an observational retrospective analysis in Area Vasta Romagna, Italy, collecting information on tumour marker determination in 760 consecutive patients who started a new line of anticancer therapy between January and June 2010. The determination of well-known biomarkers was requested for all gastrointestinal stromal tumour (GIST) patients (n=13) and for almost all breast cancer patients (n=369), and targeted therapies were consequently prescribed. Conversely, Kirsten rat sarcoma viral oncogene homolog ( KRAS ) determination in colon cancer patients (n=177) was requested in ~50% of advanced cases, while epidermal growth factor receptor ( EGFR ) determination was required in slightly more than 30% of the same patients. EGFR and KRAS determinations were requested in only 15% and 7.5% of non-small cell lung cancer (NSCLC) patients (n=201), respectively. There would appear to be greater appropriateness of tumour marker determination for breast cancer and GISTs than for colon cancer and NSCLC. Resources can be further optimised by standardising tumour marker determinations in terms of the timing of requests and the consequent use of the results for tailored treatment planning.

The efficacy of temozolomide (TMZ) plus radiation therapy (RT) in elderly patients with glioblastoma is unclear. We performed a large multicenter retrospective study to analyze prognostic factors and clinical outcome in these patients. Inclusion criteria were age ≥65 years, newly histologically confirmed glioblastoma, ECOG PS 0-2, adjuvant treatment with RT plus TMZ. We enrolled 237 patients; the average age was 71 and ECOG PS was 0-1 in 196 patients; gross total resection was performed in 174 cases. MGMT was analyzed in 151 persons and was methylated in 56 %. IDH1 was assessed in 100 patients and was mutated in 6 %. Seventy-one patients were treated with RT 40 Gy and 166 with RT 60 Gy. Progression-free survival and overall survival (OS) were 11.3 and 17.3 months, respectively. Overall survival was 19.4 vs 13.8 months for patients treated with RT 60 Gy and 40 Gy (p = 0.02); OS was 17.7 versus 16.1 months for patients treated with gross total resection vs partial surgery (p = 0.02); OS was 21.2 versus 13.6 months for methylated and unmethylated MGMT (p < 0.001). On multivariate analysis, gross total resection, RT 60 Gy, methylated MGMT and ECOG PS 0-1 were independent predictors of longer survival. Twenty-five patients (10 %) had grade 3-4 haematological toxicity during the concomitant treatment. We showed that, in elderly patients in good clinical condition treated with concomitant treatment, standard-course irradiation might be more effective than short-course irradiation. Methylated MGMT remains the most important prognostic factor.

Aim: To evaluate the optimal time interval from definitive surgery to commencing chemotherapy in early breast cancer (EBC)., Patients and Methods: The relationship between time to initiation of adjuvant chemotherapy (TTC), calculated in weeks, and disease-free (DFS) or overall survival (OS), was assessed in 921 EBC patients with rapidly proliferating tumours (thymidine labelling index >3% or G3 or Ki67 >20%), randomised in a phase III clinical trial (NCT01031030) to receive chemotherapy with or without anthracyclines (epirubicin→cyclophosphamide, methotrexate and fluorouracil (CMF) versus CMF→epirubicin versus CMF). DFS, OS and 95% confidence intervals (95% confidence interval (CI)) were calculated by the Kaplan-Meier method. Multivariate Cox analysis was performed in relation with nodal involvement, oestrogen receptor and human epidermal growth factor receptor 2 (HER2) status, Ki67 value, type of adjuvant chemotherapy, menopausal status and tumour size., Results: At a median follow-up of 105 months (range 2-188), a prolonged TTC resulted in a significant increase in the risk of relapse: hazard ratio (HR) 1.15 (95% CI 1.02-1.30, p=0.019). Using a backward elimination procedure, TTC, tumour size and nodal involvement remained significantly associated with DFS. A time-dependent receiver-operating characteristic (ROC) curve analysis was subsequently utilised to evaluate the best cut-off for TTC, identifying 7 weeks as the best threshold for longer OS (p=0.043): 8-year OS 88% (95% CI 85-90) for patients with a TTC <7 weeks and 78% (95% CI 68-87) for the other group., Conclusions: Our results confirm that a shorter TTC may reduce relapses and possibly also improve clinical outcome in patients with highly proliferating EBC., (Copyright © 2015 Elsevier Ltd.

Background: As yet, no population-based prospective studies have been conducted to investigate the incidence and clinical outcome of glioblastoma (GBM) or the diffusion and impact of the current standard therapeutic approach in newly diagnosed patients younger than aged 70 years., Methods: Data on all new cases of primary brain tumors observed from January 1, 2009, to December 31, 2010, in adults residing within the Emilia-Romagna region were recorded in a prospective registry in the Project of Emilia Romagna on Neuro-Oncology (PERNO). Based on the data from this registry, a prospective evaluation was made of the treatment efficacy and outcome in GBM patients., Results: Two hundred sixty-seven GBM patients (median age, 64 y; range, 29-84 y) were enrolled. The median overall survival (OS) was 10.7 months (95% CI, 9.2-12.4). The 139 patients ≤aged 70 years who were given standard temozolomide treatment concomitant with and adjuvant to radiotherapy had a median OS of 16.4 months (95% CI, 14.0-18.5). With multivariate analysis, OS correlated significantly with KPS (HR = 0.458; 95% CI, 0.248-0.847; P = .0127), MGMT methylation status (HR = 0.612; 95% CI, 0.388-0.966; P = .0350), and treatment received in a high versus low-volume center (HR = 0.56; 95% CI, 0.328-0.986; P = .0446)., Conclusions: The median OS following standard temozolomide treatment concurrent with and adjuvant to radiotherapy given to (72.8% of) patients aged ≤70 years is consistent with findings reported from randomized phase III trials. The volume and expertise of the treatment center should be further investigated as a prognostic factor.

Purpose: Guideline consistency in the prevention of chemotherapy-induced nausea and vomiting (CINV) remains low (29% in the Pan European Emesis Registry study) and very low (11%) in regimens with a high emetogenic risk. The aim of this study was to evaluate the guideline consistency of CINV prophylaxis for acute emesis in daily clinical practice in Italy., Methods: This was a prospective, observational, multicenter study. Patients scheduled to receive antitumor treatment on a single prespecified day were included. Data on patient characteristics (demographic and clinical), type of anticancer therapy, and type of antiemetic therapy prescribed for acute emesis were collected on electronic data capture forms. Chemotherapy regimens and antiemetic prophylaxis were categorized according to the MASCC 2011 guidelines. The study was approved by the local ethics committees., Results: From July 2013 to February 2014, a total of 502 patients were enrolled at 26 study sites. Median age was 62 years (range 27-87 years). Colorectal cancer and breast cancer were the most common malignancies. The emetogenic potential of the chemotherapy regimens used was high (HEC) (23.7%), moderate (MEC) (40.6%), low (31.3%) or minimal (4.4%). Overall, guideline consistency was 19.3%. Consistency reached 45% when the various 5HT3 receptor antagonists were considered equivalent and interchangeable in MEC regimens. Adherence to guidelines was lowest for MEC and Minimal risk groups. Ten percent of patients in HEC and MEC regimens did not receive any 5HT3 receptor antagonists. NK1 receptor antagonists were used in 8% of all regimens., Conclusions: Our study indicates that antiemetic guideline inconsistency remains an issue in daily clinical oncology practice in Italy.

There are no validated predictors of benefit from anthracyclines. We compared cyclophosphamide, methotrexate, 5-fluorouracil (CMF), and epirubicin in different sequences with CMF alone in a phase III trial on operable breast cancers. Outcomes were analyzed in relation to tumor biological profiles to identify potential predictors of the efficacy of different treatments/drug combinations. Patients with N- or 1-3N+ tumors, were randomized to receive (a) epirubicin (4 cycles) followed by CMF (4 cycles); (b) CMF (4 cycles) followed by epirubicin (4 cycles), or (c) CMF (6 cycles) alone. Immunohistochemical assessments of estrogen (ER) and progesterone (PgR) receptors, HER2 and Ki67 were available for 705 patients (arm A/B/C: 276/269/160). Prognostic and predictive relevance was analyzed by log-rank tests and Cox models. Ki67 > 20 % and absent/low expression of ER and PgR were associated with worsen disease-free (DFS) and overall survival (OS). In patients with triple negative tumors (ER-, PgR-, HER2-), epirubicin-containing regimens yielded better DFS (HR 0.33, 95 % CI 0.17-0.62, P = 0.0007) and OS (HR 0.24, 95 % CI 0.10-0.57, P = 0.001) compared with CMF alone, whereas no differences were found in patients with HER2-positive (HER2+, ER-, PgR-) subtype. Treatment by subtype interaction (HER2-positive vs. others) was significant for DFS (χ (2) = 6.72, P = 0.009). In triple unfavorable (ER-, PgR-, Ki67 > 20 %) tumors, the use of epirubicin yielded better DFS (HR 0.45,95 % CI 0.26-0.78, P = 0.005) and OS (HR 0.30, 95 % CI 0.15-0.63, P = 0.001). Epirubicin-containing regimens seem to be superior to CMF alone in patients with highly proliferating, triple negative or triple unfavorable tumors.

Objective: Although adjuvant trastuzumab improves survival in patients with HER2-positive early breast cancer, there is growing concern about the long-term effect of trastuzumab-induced cardiotoxicity (TIC). We retrospectively assessed the incidence of TIC and heart failure (HF) to identify possible risk and protective factors., Design: Retrospective study., Setting: Institute for Cancer Research and Treatment, Medical Oncology Department., Patients: Consecutive patients who started adjuvant trastuzumab between 2007 and 2010., Main Outcome: Measures TIC was defined as an absolute left ventricular ejection fraction (LVEF) decrease ≥ 15 points from baseline or a LVEF<50%. Logistic regression was used to estimate OR and their 95% CI in order to evaluate the risk of TIC, considering potential cardiac risk factors (hypertension, hypercholesterolaemia, diabetes mellitus, smoke, cardiac ischaemia and previous chest radiotherapy) and protective factors (β-blockers, ACE inhibitors and/or angiotensin receptor blockers)., Results: Among 179 patients, 78 cases of TIC (44%, 95% CI 37% to 51%) and four cases of HF (2%, 95% CI 0% to 4%) were reported. 14 patients stopped trastuzumab as a result of TIC. None of the cardiac risk factors or concomitant cardiovascular medications altered the risk of TIC. A previous cumulative dose >240 mg/m(2) of doxorubicin or >500 mg/m(2) of epirubicin increased the risk of TIC compared with lower doses (OR 3.07; 95% CI 1.29 to 7.27, p=0.0011)., Conclusions: TIC is a frequent, albeit generally mild, adverse event in clinical practice. Further studies are warranted to better define the risk of and protective factors for TIC.

We previously described a cohort of grade II oligodendroglioma (OII) patients, in whom the loss of heterozygosity (LOH) 19q was present in the subgroup at a higher risk of relapse. In this study, we evaluated the CpG methylation of the putative tumor suppressor epithelial membrane protein 3 (EMP3, 19q13.3) gene promoter in the same OII cohort, to investigate whether a correlation could be found between EMP3 cytogenetic and epigenetic loss and higher risk of relapse. Twenty-three tumor samples from OII patients were collected over a period of 10 years. Seventeen glioblastoma (GBM) samples (2 of which were relapses) were collected from 15 patients. The EMP3, O6-methylguanine methyltransferase (MGMT) and cyclooxygenase 2 (COX2) promoter methylation, evaluated by methylation-specific PCR, and the isocitrate dehydrogenase 1 (IDH1) mutation, identified by sequencing, were compared between the OII and GBM histotypes. The EMP3 promoter methylation was correlated with the analysis of LOH 19q, performed by microsatellite amplification, in OII patients. Disease progression-free interval was evaluated in the OII patients with the EMP3 methylation with either LOH 19q or conserved chromosome 19 arms. The EMP3 and MGMT promoter methylation was more frequent in OII than in GBM patients, and the IDH1 mutation was absent in GBM. The COX2 promoter was unmethylated in both histotypes. Both LOH+/- 19q OII patients showed EMP3 hypermethylation. Concomitant LOH 19q and EMP3 gene promoter methylation was observed in the OII patients at a higher risk of relapse. Our results suggest that a total (cytogenetic and epigenetic) functional loss of both EMP3 alleles accounts for the reduced disease progression-free interval in OII patients. Although the small sample size limits the strength of this study, our results support testing this hypothesis in larger cohorts of patients, considering the methylation of the EMP3 gene promoter together with LOH 19q as an indication for treatment with adjuvant therapy ab initio in order to improve the overall survival of OII patients.

Adjuvant cyclophosphamide, methotrexate, and 5-fluorouracil (CMF) have proven highly effective in rapidly proliferating breast cancer (RPBC). It has also been seen that sequential administration of doxorubicin and CMF is superior to their alternation, especially in indolent tumors. In a phase III study, we evaluated whether adjuvant epirubicin (E) followed by CMF is superior to the inverse sequence in RPBC. Patients with node-negative or 1-3 node-positive RPBC (Thymidine Labeling Index > 3% or histological grade 3 or S-phase > 10% or Ki67 > 20%) were randomized to receive E (100 mg/m(2) i.v. d1, q21 days for 4 cycles) followed by CMF (600, 40, 600 mg/m(2) i.v. d1 and 8, q28 days for 4 cycles) (E → CMF) or CMF followed by E (CMF → E) or CMF for 6 cycles. From November 1997 to December 2004, 1066 patients were enrolled: E → CMF 440, CMF → E 438, and CMF 188. At a median follow-up of 69 months, 5-year OS was 91% (95% CI 88-94) for E → CMF and 93% (95% CI 90-95) for CMF → E, with adjusted hazard ratio of 0.88 (95% CI 0.58-1.35), and DFS was 80% in both arms, with adjusted hazard ratio of 0.99 (95% CI 0.73-1.33, Cox model). Adverse events were similar, apart from a higher rate of neutropenia in the CMF → E arm. No important differences in clinical outcome were observed between the two different sequences, making both a valid option in early breast cancer. Further molecular characterization of the tumors might help to identify subgroups achieving higher benefit from either sequence.

Oligodendrogliomas are rare primary brain tumors with variable patient outcomes which are not always adequately accounted for by clinical or pathological variables. The present study evaluated the prognostic implications of chromosome 1p and 19q status in a set of 23 low grade oligodendrogliomas (OGD II), and correlated the results with patient outcome. Loss of heterozygosity (LOH) and fluorescent in situ hybridization (FISH) analyses, the most widely used standard procedures, were used. 1p and 19q deletions were found in 65 and 61% of cases, respectively, using FISH and in 78 and 72% of cases using LOH. Both deletions were found in 56 and 64% of patients using FISH and LOH, respectively. Concordance between the results from the two techniques, determined by the Kappa statistics, ranged from fair to substantial depending on whether single or combined deletions were considered. Our results showed that the molecular alterations are associated with age and tumor localization. With regard to the impact of chromosomal alterations on clinical outcome, chromosome 19q deletions detected by LOH would seem to indicate a subgroup of patients at a higher risk of relapse, although the small number of patients recruited does not permit any definitive conclusions to be drawn. Further studies are now ongoing to determine whether this methodological approach could be potentially useful in low grade oligodendrogliomas to better characterize chromosomal alterations of 1p/19q and identify subgroups of patients with a higher risk of disease recurrence.

Objective: Breast cancer patients with >3 involved nodes (N+) have a poor outcome. Chemotherapy (CT), alone or combined with endocrine therapy (ET) in hormone receptor (HOR)-positive patients, is the standard for these women. However, there are still questions surrounding the optimal adjuvant CT regimen., Methods: 244 patients with >3 N+ were randomized to receive either four 3-weekly courses of epirubicin (E: 100 mg/m(2), day 1) followed by four 4-weekly cycles of cyclophosphamide, methotrexate and 5-fluorouracil (CMF: 600, 40, 600 mg/m(2), days 1, 8: n = 122) or four 3-weekly courses of paclitaxel (T: 175 mg/m(2), day 1) followed by four 3-weekly cycles of epirubicin and vinorelbine (E: 75 mg/m(2), day 1; V: 25 mg/m(2), days 1, 8: n = 122). After CT, tamoxifen (plus an LH-RH analog in menstruating women) was given to all HOR-positive patients over a period of 5 years. Overall survival (OS) was the primary end point. Relapse-free survival (RFS) and toxicity were secondary end points., Results: At a median follow-up time of 102 months (range 3-146), OS and RFS did not differ significantly between groups (E-CMF vs. T-EV: OS, HR 0.94, 95% CI 0.59-1.48, p = 0.8; RFS, HR 0.86, 95% CI 0.57-1.29, p = 0.45). The lack of any difference between assigned treatments was confirmed by multivariate analysis (E-CMF vs. T-EV: RFS, HR 0.98, 95% CI 0.64-1.48, p = 0.9). The 2 regimens showed different toxicity profiles. In fact, significantly more women assigned to E-CMF were affected by stomatitis (p = 0.001) while significantly more women in the T-EV group developed peripheral neuropathy (p < 0.0001) and musculoskeletal disorders (p < 0.0001). However, side effects were moderate and manageable and no toxic death occurred in either arm of the study., Conclusions: T-EV was safe and moderately toxic but was not superior to E-CMF., (Copyright 2010 S.

Background: Standardized salvage treatment has not yet proved effective in glioblastoma multiforme (GBM) patients who receive prior standard radiotherapy plus concomitant and adjuvant temozolomide., Methods: Patients with progressive GBM after radiotherapy plus concomitant and/or adjuvant temozolomide received three-weekly doses (100-75 mg m(2)) of fotemustine followed, after a 5-week rest, by fotemustine (100 mg m(2)) every 3 weeks for < or =1 year., Results: Forty-three patients (29 M, 14 F; median age 51 years, range 34-68; median KPS 90) were enrolled. Progression-free survival at 6 months (PFS-6) was 20.9% (95% CI: 9-33%); three patients (7.1%) had partial response (PR); 15 (34.9%), disease stabilization (SD). The median survival was 6 months (95% CI: 5-7). MGMT promoter status was methylated in 8 (18.6%) and unmethylated in 26 (60.5%) and not assessable in 9 (20.9%) patients, respectively. Disease control was 75% versus 34.6% in methylated and unmethylated MGMT patients (P = 0.044); no significant difference was found between groups for PFS-6 and survival. Grade 3 and 4 thrombocytopenia and neutropenia were observed in 20.9 and 16.3% of patients, during the induction phase, and in 0 and 9.5% patients during the maintenance phase, respectively., Conclusions: The findings of the present trial, that evaluate fotemustine in a homogeneous population, may represent a new benchmark for nitrosourea activity. Moreover, this is the first study to evaluate correlation between MGMT promoter status and outcome of fotemustine for relapsing GBM previously treated with radiotherapy and temozolomide.

Methotrexate (MTX)-based chemotherapy extends survival in patients with primary brain lymphomas, but it is not clear whether multiagent chemotherapy is superior to MTX alone. Treatment options for patients with recurrent primary brain lymphoma are limited; there is no standard second-line chemotherapy. New chemotherapeutic agents with clear activity in brain lymphoma are needed for treatment of recurrent disease. We report the results of a phase II trial assessing activity of the alkylating agent temozolomide in immunocompetent patients with recurrent primary brain lymphomas, previously treated with high-dose MTX-containing chemotherapy and/or radiotherapy. A median of two courses (range 1-12) of temozolomide 150 mg m-2 day-1, for 5 days every 4 weeks was administered to 36 patients yielding nine complete and two partial responses (response rate: 31%; 95% confidence interval 16-46%). One-year survival was 31% (95% confidence interval 16-46%). Toxicity was negligible. We conclude that temozolomide is active in recurrent primary brain lymphomas and should further be evaluated in this disease, perhaps in combination with MTX as initial treatment.

All consecutive patients with advanced gastric carcinoma who came to the Oncology Dept. of the "L. Pierantoni Hospital" in Forlì, between June 1, 1980 and August 30, 1983, were treated with 5-fluorouracil, adriamycin and mitomycin C (FAM). None of the patients had previously received chemotherapy. The dominant location of metastasis was the liver in 21 pts (48.8%), the abdomen in 15 pts (34.8%) and distant organs in 7 pts (16.2%). The schedule of FAM regimen used was: 5 Fluorouracil, 600 mg/m2, days 1, 8, 29, 36; Mitomycin C 10, mg/m2, day 1; Adriamycin, 30 mg/m2, days 1, 29. Complete remission (CR) was reached in 2 pts (4.6%) with a median length of response (m.l.r.) of 55 weeks (range 20-90), partial remission (PR) in 9 pts (20.9%) with a m.l.r. of 15.1 weeks (2.2-60), no change (N.C.) in 19 pts (44%) with a m.l.r. of 10 weeks (2.2-54) and progression (P) in 13 pts (30.2%). Median survival of patients in CR + PR considered together was 48 weeks (12 months), for the NC pts 20 weeks (5 months) and for those in P 14.1 weeks (3.5 months). The authors reached the conclusion that gastric carcinoma may be treated with FAM both for palliation and to improve survival even if in a small number of patients.

Relapse rates of 75 patients with previously untreated Hodgkin's disease with stages I and II nodular sclerosis were analyzed according to the mediastinal involvement. The overall relapse rate was 22.6%. The probability of relapse was much greater for patients with large mediastinal involvement (66.6%) compared with 17% for patients with small mass, and 11.7% of patients without mediastinal involvement (P less than 0.001). There was no significant difference in recurrence rates between patients without mediastinal mass and patients with a small mass, and in these patients adjuvant chemotherapy MOPP after radiotherapy showed an evident benefit in reducing the relapse rate. On the other hand, no beneficial effect of adjuvant chemotherapy was observed in patients with large mediastinal involvement. Finally, in the 17 relapsing patients, 'salvage' chemotherapy was less effective in patients with large mediastinal mass than in those with small or no mediastinal involvement.
