RESUMO

Debate is around the optimal immunization regimen for cancer vaccines since too intense vaccination schedules may exhaust reactive lymphocytes. GX301 is a telomerase-based cancer vaccine whose safety and immunological effects were tested in a phase I trial applying an eight administrations schedule. Main objective of this study was to comparatively analyse safety and immunological response to three GX301 regimens in metastatic castration-resistant prostate cancer patients with response/disease stability after docetaxel chemotherapy. This was a multicentre, randomized, parallel-group, open-label trial registered with EudraCT (2014-000095-26) and ClinicalTrials.gov (NCT02293707, 2014). Ninety-eight patients were randomized to receive either eight (regimen 1), four (regimen 2) or two (regimen 3) vaccine administrations. Sixty-three patients were assessable for the primary immunological end-point. Vaccine-specific immune responses were evaluated by intracellular staining for IFN, elispot and cytotoxic assay at 90 and 180 days from baseline. No major side effects were recorded. A 54% overall immune responder rate was observed with 95% of patients showing at least one vaccine-specific immune response. Rate of immunological responders and number of immunizations were proportionally related, suggesting superiority of regimens 1 and 2 over regimen 3. Overall survival did not differ among regimens in both immunological responders and non-responders and was inversely associated (P = 0.002) with increase in the number of circulating CD8 + T regulatory cells at 180 days. These data indicate that GX301 cancer vaccine is safe and immunogenic in metastatic castration-resistant prostate cancer patients. Schedules with high number of administrations should be preferred in future studies due to their better immunological outcome.

RESUMO

BACKGROUND: Until now, no robust data supported the efficacy, safety and recommendation for influenza vaccination in patients with cancer receiving immune checkpoint inhibitors (ICIs). METHODS: The prospective multicenter observational INfluenza Vaccine Indication During therapy with Immune checkpoint inhibitors (INVIDIa-2) study investigated the clinical effectiveness of influenza vaccination in patients with advanced cancer receiving ICIs, enrolled in 82 Italian centers from October 2019 to January 2020. The primary endpoint was the time-adjusted incidence of influenza-like illness (ILI) until April 30, 2020. Secondary endpoints regarded ILI severity and vaccine safety. RESULTS: The study enrolled 1279 patients; 1188 patients were evaluable for the primary endpoint analysis. Of them, 48.9% (581) received influenza vaccination. The overall ILI incidence was 8.2% (98 patients). Vaccinated patients were significantly more frequently elderly (p<0.0001), males (p=0.004), with poor European Cooperative Oncology Group performance status (p=0.009), affected by lung cancer (p=0.01), and by other non-cancer comorbidities (p<0.0001) when compared with unvaccinated. ILI incidence was not different basing on influenza vaccination: the time-to-ILI was similar in vaccinated and unvaccinated patients (p=0.62). ILI complications were significantly less frequent for patients receiving the vaccination (11.8% vs 38.3% in unvaccinated, p=0.002). ILI-related intravenous therapies were significantly less frequent in vaccinated patients than in unvaccinated (11.8% vs 29.8%, p=0.027). ILI lethality was, respectively, 0% in vaccinated and 4.3% in unvaccinated patients. Vaccine-related adverse events were rare and mild (1.5%, grades 1-2). CONCLUSION: The INVIDIa-2 study results support a positive recommendation for influenza vaccination in patients with advanced cancer receiving immunotherapy.

RESUMO

BACKGROUND: Bone remodeling is disrupted in metastatic disease, which affects > 70% of metastatic castration-resistant prostate cancer (mCRPC) patients. As a result, abnormal levels of specific bone turnover biomarkers (BTMs) are released. In this prospective ancillary analysis of the Italian real-world study ABITUDE, four markers were measured during abiraterone acetate plus prednisone (AAP) treatment in chemotherapy-naïve mCRPC men failing androgen-deprivation therapy. METHODS: Patients were enrolled if a blood sample was obtained before the first administration of abiraterone (baseline); ad-hoc blood samples were withdrawn during routine tests after 3, 6, and 12 months. A centralized lab measured bone alkaline phosphatase (BALP, osteoblast activity marker), type-I collagen-C-telopeptide (CTX-1, bone resorption marker), parathyroid hormone (PTH) and vitamin D (vitD). At each time point, intra-patient variations vs baseline were compared by the signed-rank test (statistical significance: P-value < 0.05). RESULTS: Of 481 patients enrolled in ABITUDE, 186 (median age: 76 [range: 53-93] years) met the substudy criteria: 74.7% had bone metastases, 11.8% were on bone-targeted therapies (BTT) and 14.0% on vitD supplementation. BALP decreased significantly at month 6 (P = 0.0010) and 12 (P < 0.0001) and CTX-1 at month 6 (P = 0.0028); PTH increased at month 3 (P < 0.0001); no significant difference in vitD levels was observed. Similar findings were observed in BTT-untreated patients. The reduction in BALP and CTX-1 levels was more pronounced in patients with than without bone metastases; in the latter group, no significant variation in BALP and CTX-1 levels was observed. CONCLUSIONS: AAP seems to exert an effect on the microenvironment of metastatic but not of normal bone, which likely contributes to its antitumoral activity.

RESUMO

BACKGROUND: Real-world data on chemotherapy-naïve patients with metastatic castration-resistant prostate cancer (mCRPC) treated with abiraterone plus prednisone are limited, largely deriving from small retrospective studies. METHODS: ABitude is an Italian, observational, prospective, multicenter study of mCRPC patients receiving abiraterone plus prednisone in clinical practice. Chemotherapy-naïve mCRPC patients were consecutively enrolled at abiraterone start (February 2016 to June 2017) and are being followed for 3 years, with evaluation approximately every 6 months. Several clinical and patients reported outcomes were examined. RESULTS: In this second interim analysis, among 481 enrolled patients, 453 were evaluable for analyses. At baseline, the median age was 77 years and ~69% of patients had comorbidities (mainly cardiovascular diseases). Metastases were located mainly at bones and lymph nodes; 8.4% of patients had visceral metastases. During a median follow-up of 18 months, 1- and 2-year probability of radiographic progression-free survival were 73.9% and 56.2%, respectively; the corresponding rates for overall survival were 87.3% and 70.4%. In multivariable analyses, the number of bone metastases significantly affected radiographic progression-free survival and overall survival. During abiraterone plus prednisone treatment, 65% of patients had a ⩾50% prostate-specific antigen decline, and quality of life remained appreciably high. Among symptomatic patients according to the Brief Pain Inventory) (32%), scores significantly declined after 6 months of treatment. Overall, eight patients (1.7%) had serious adverse reactions to abiraterone. CONCLUSIONS: Abiraterone plus prednisone is effective and safe for chemotherapy-naïve mCRPC patients in clinical practice.

RESUMO

BACKGROUND: This prospective, multicentre, observational INVIDIa-2 study is investigating the clinical efficacy of influenza vaccination in advanced-cancer patients receiving immune-checkpoint inhibitors (ICIs), enrolled in 82 Italian centres, from October 2019 to January 2020. The primary endpoint was the incidence of influenza-like illness (ILI) until 30 April 2020. All the ILI episodes, laboratory tests, complications, hospitalizations and pneumonitis were recorded. Therefore, the study prospectively recorded all the COVID-19 ILI events. PATIENTS AND METHODS: Patients were included in this non-prespecified COVID-19 analysis, if alive on 31 January 2020, when the Italian government declared the national emergency. The prevalence of confirmed COVID-19 cases was detected as ILI episode with laboratory confirmation of SARS-CoV-2. Cases with clinical-radiological diagnosis of COVID-19 (COVID-like ILIs), were also reported. RESULTS: Out of 1257 enrolled patients, 955 matched the inclusion criteria for this unplanned analysis. From 31 January to 30 April 2020, 66 patients had ILI: 9 of 955 cases were confirmed COVID-19 ILIs, with prevalence of 0.9% [95% confidence interval (CI): 0.3-2.4], a hospitalization rate of 100% and a mortality rate of 77.8%. Including 5 COVID-like ILIs, the overall COVID-19 prevalence was 1.5% (95% CI: 0.5-3.1), with 100% hospitalization and 64% mortality. The presence of elderly, males and comorbidities was significantly higher among patients vaccinated against influenza versus unvaccinated (p = 0.009, p < 0.0001, p < 0.0001). Overall COVID-19 prevalence was 1.2% for vaccinated (six of 482 cases, all confirmed) and 1.7% for unvaccinated (8 of 473, 3 confirmed COVID-19 and 5 COVID-like), p = 0.52. The difference remained non-significant, considering confirmed COVID-19 only (p = 0.33). CONCLUSION: COVID-19 has a meaningful clinical impact on the cancer-patient population receiving ICIs, with high prevalence, hospitalization and an alarming mortality rate among symptomatic cases. Influenza vaccination does not protect from SARS-CoV-2 infection.

RESUMO

BACKGROUND: Patients with cancer are at increased risk of complicated severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection, but it is still unclear if the risk of mortality is influenced by cancer type or ongoing anti-cancer treatments. An interesting debate concerning the potential relationship between androgen deprivation therapy (ADT) and SARS-CoV-2 infection has recently been opened in the case of prostate cancer (PC), and the aim of this multi-centre cohort study was to investigate the incidence and outcomes of SARS-CoV-2 infection in patients with metastatic castration-resistant prostrate cancer (mCRPC). PATIENTS AND METHODS: We retrospectively reviewed the clinical records of patients with mCRPC who developed SARS-CoV-2 infection, and recorded their baseline clinical characteristics, their history of PC and SARS-CoV-2 infection, and their oncological status and treatment at the time of infection. The primary study end point was the death rate and the possible impact of the patients' PC-related history and treatments on mortality. RESULTS: Thirty-four of the 1433 patients with mCRPC attending the participating centres (2.3%) developed SARS-CoV-2 infection, 22 (64.7%) of whom were hospitalised. Most of the patients were symptomatic, the most frequent symptoms being fever (70.6%), dyspnoea (61.8%), cough (52.9%) and fatigue (38.2%). After a median follow-up of 21 days (interquartile range: 13-41), 13 patients had died (38.2%), 17 recovered (50.0%) and four (11.7%) were still infected. The number of treatments previously administered for mCRPC had a significant impact on mortality (p = 0.004). CONCLUSIONS: Our findings contribute additional data to the current debate concerning the postulated protective role of ADT, which seems to be less in patients with metastatic PC.

RESUMO

BACKGROUND: Previous studies demonstrated a predictive value of prostate-specific antigen (PSA) kinetics for treatment outcome. Our retrospective study evaluates the prognostic role of early PSA drop in metastatic castration resistant prostate cancer (mCRPC) patients receiving abiraterone acetate (AA) or enzalutamide (E). METHODS: All mCRPC patients treated with AA or E at the San Luigi Hospital in Orbassano between 2010 and 2018 and at the Ordine Mauriziano Hospital in Turin between 2014 and 2018 were included in this retrospective study. Only patients with an early PSA (measured 28-60 days after the beginning of the treatment) were included in the analysis. Patients were divided in early responders and non-early responders according to early PSA response (drop≥50% from baseline). Univariate and multivariate analyses for progression free survival (PFS) and overall survival (OS) were performed. RESULTS: Of 144 patients with early PSA value, 61 (42.4%) patients received E (docetaxel-naïve 42, post-docetaxel 19) and 83 (57.6%) received AA (docetaxel-naïve 44, post-docetaxel 39). Seventy-five (52.1%) patients achieved early PSA drop. In docetaxel-naïve setting (N.=86), median PFS was 14.9 (with early PSA drop) vs. 8.8 months (without early PSA drop, P=0.001). In post-docetaxel setting (N.=58) median PFS was 11.9 vs. 4.5 months (P<0.001). Globally, median PFS was 14.9 vs. 6.3 months in patients with and without early PSA drop, respectively (P<0.001). In docetaxel-naïve setting, patients with early PSA drop had a median OS of 39.5 vs. 18.8 months (P=0.12). In post-docetaxel setting median OS was 29.6 vs. 10.7 months (P=0.01). Comprehensively, median OS was 31.9 vs. 16.3 (P=0.002) in patients with and without early PSA drop, respectively. At multivariate analysis, early PSA drop confirmed an independent association with PFS (HR 0.21; 95% CI: 0.12-0.38, P<0.001) and OS (HR 0.25; 95% CI: 0.12-0.50, P<0.001). CONCLUSIONS: mCRPC patients treated with AA or E, in docetaxel-naïve or post-docetaxel setting, with early PSA drop had significantly better OS and PFS.

RESUMO

OBJECTIVE: To evaluate the efficacy of orvepitant (10 or 30 mg given once daily, orally for 4 weeks), a neurokinin-1 receptor antagonist, compared with placebo in reducing the intensity of epidermal growth factor receptor inhibitor (EGFRI)-induced intense pruritus. DESIGN: Randomised, double-blind, placebo-controlled clinical trial. SETTING: 15 hospitals in Italy and five hospitals in the UK. PARTICIPANTS: 44 patients aged ≥18 years receiving an EGFRI for a histologically confirmed malignant solid tumour and experiencing moderate or intense pruritus after EGFRI treatment. INTERVENTION: 30 or 10 mg orvepitant or placebo tablets once daily for 4 weeks (randomised 1:1:1). PRIMARY AND SECONDARY OUTCOME MEASURES: The primary endpoint was change from baseline in mean patient-recorded numerical rating scale (NRS) score (over the last three recordings) at week 4. Secondary outcome measures were NRS score, verbal rating scale score, Skindex-16 and Leeds Sleep Evaluation Questionnaire at each study visit (baseline, weeks 1, 4, 8); rescue medication use; EGFRI dose reduction; and study withdrawal because of intense uncontrolled pruritus. RESULTS: The trial was terminated early because of recruitment challenges; only 44 of the planned 90 patients were randomised. All patients were analysed for efficacy and safety. Mean NRS score change from baseline to week 4 was -2.78 (SD: 2.64) points in the 30 mg group, -3.04 (SD: 3.06) points in the 10 mg group and -3.21 (SD: 1.77) points in the placebo group; the difference between orvepitant and placebo was not statistically significant. No safety signal was detected. Adverse events related to orvepitant (asthenia, dizziness, dry mouth, hyperhidrosis) were all of mild or moderate severity. CONCLUSIONS: Orvepitant was safe and well tolerated. No difference in NRS score between the orvepitant and placebo groups was observed at the week 4 primary endpoint. A number of explanations for this outcome are possible. TRIAL REGISTRATION NUMBER: EudraCT2013-002763-25.

RESUMO

BACKGROUND: Neutropenia is a common side effect associated with docetaxel use. We retrospectively investigated the association between chemotherapy-induced neutropenia and survival in metastatic castration-resistant prostate cancer (mCRPC) patients receiving first-line docetaxel. PATIENTS AND METHODS: Metastatic castration-resistant prostate cancer patients treated with first-line docetaxel, with known neutrophils value 10 days after first administration, were included in this retrospective analysis. Neutropenia was categorized in Grade 0 to 1 (G0-1), Grade 2 to 3 (G2-3), and Grade 4 (G4). Outcome measures were progression-free survival (PFS) and overall survival (OS). RESULTS: Eighty patients were analyzed. Median PFS was 5.4 months in patients with G0-1 neutropenia, 6.9 months with G2-3 neutropenia (hazard ratio [HR] vs. G0-1, 0.69; 95% confidence interval [CI], 0.35-1.35; P = .27) and 9.5 months with G4 neutropenia (HR vs. G0-1, 0.30; 95% CI, 0.16-0.57; P < .0001). Median OS was 11.6 months in patients with G0-1 neutropenia, 25.5 months in patients with G2-3 neutropenia (HR vs. G0-1, 0.36; 95% CI, 0.16-0.80; P = .012) and 39.3 months in patients with G4 neutropenia (HR vs. G0-1, 0.19; 95% CI, 0.09-0.41; P < .0001). In multivariate analysis, the occurrence of severe neutropenia showed a statistically significant association with OS (HR G4 vs. G0-1, 0.14; 95% CI, 0.03-0.67; P = .013; HR G2-3 vs. G0-1, 0.42; 95% CI, 0.11-1.57; P = .20) and PFS (HR G4 vs. G0-1, 0.28; 95% CI, 0.09-0.86; P = .03; HR G2-3 vs. G0-1, 1.07; 95% CI, 0.38-2.96; P = .90). CONCLUSION: Docetaxel-induced neutropenia is associated with better survival of mCRPC.

RESUMO

BACKGROUND: The neutrophil-to-lymphocyte ratio (NLR), a measure of systemic inflammatory response, has been associated with poor outcome in several solid tumors, including prostate cancer. We retrospectively investigated the prognostic role of pretreatment NLR in metastatic castration-resistant prostate cancer (mCRPC) patients treated with first-line docetaxel. METHODS: All CRPC patients treated with first-line docetaxel at two Italian institutions, with available data about baseline neutrophil and lymphocyte values, were included in this retrospective analysis. Patients were divided in two groups according to NLR ratio (low NLR: ≤3; high NLR: >3). Outcome measures were progression-free (PFS) and overall survival (OS), measured from the start of docetaxel treatment. Univariate and multivariate analysis (adjusting for baseline prostate-specific antigen, alkaline phosphatase, lactate dehydrogenase, hemoglobin, albumin, performance status, use of opioids and presence of visceral disease) were performed. RESULTS: One hundred and seventy-nine patients treated between 2004 and 2016 were analyzed and 110 had information about pretreatment NLR. Forty-six patients (42%) had low NLR and 64 (58%) had high NLR. Median PFS was 8.8 months in patients with low NLR versus 7.3 months in those with high NLR [hazard ratio (HR) 1.12, 95% confidence interval (CI) 0.75-1.69, p = .58]. Median OS was 34.9 months in patients with low NLR versus 20.2 months in those with high NLR (HR 1.85, 95% CI 1.07-3.19, p = .02). At multivariate analysis, NLR confirmed an independent impact on OS (HR 3.16, 95% CI 1.50-6.65, p = .002). CONCLUSION: In this retrospective series, metastatic CRPC patients who started first-line docetaxel with a low pretreatment NLR had a significantly better survival. In addition to known prognostic factors, NLR can be useful to improve prognostic evaluation of patients in this setting.

RESUMO

Osteonecrosis of the jaw (ONJ) associated with the use of bisphosphonates has been rarely reported in metastatic renal cell cancer (RCC) patients. Since the introduction of combined therapies consisting of nitrogen-containing bisphosphonates (NBPs) and targeted agents, an increasing number of RCC patients were reported to develop ONJ, suggesting that therapeutic angiogenesis suppression might increase the risk of ONJ in NBPs users. We performed a multicenter retrospective study and reviewed literature data to assess the occurrence and to investigate the nature of ONJ in RCC patients taking NBPs and targeted agents. Nine Italian Centers contributed to the data collection. Patients with exposed and nonexposed ONJ were eligible for the study if they had been taking NBPs and were receiving targeted agents at the time of ONJ diagnosis. Forty-four RCC patients were studied. Patients were mostly male (82%), with a median age of 63 years (range, 45-85 years). Zoledronic acid (93%) and sunitinib (80%) were the most frequently used NBP and antiangiogenic agent, respectively. Other agents included Pamidronate, ibandronate, sorafenib, bevacizumab, mammalian target of rapamycin inhibitors. Forty-nine sites of ONJ were encountered, with the mandible being the preferred site of ONJ (52%); both jaws were affected in 5 cases (12%). The most common precipitating event was dental/periodontal infection (34%), followed by tooth extraction (30%). Oral triggers of ONJ were missing in 10 cases (23%). This unexpectedly high number of ONJ cases, in comparison with literature data, suggests that frequency of ONJ in RCC patients might be largely underestimated and suggests a potential role for targeted agents in the incremental risk of ONJ.

RESUMO

UNLABELLED: Gross cystic disease (GCDB) is a breast benign condition predisposing to breast cancer. Cryopreserved sera from GCDB patients, some of whom later developed a cancer (cases), were studied to identify potential risk markers. A MALDI-TOF mass spectrometry analysis found several complement C3f fragments having a significant increased abundance in cases compared to controls. After multivariate analysis, the full-length form of C3f maintained a predictive value of breast cancer risk. Higher levels of C3f in the serum of women affected by a benign condition like GCDB thus appears to be correlated to the development of breast cancer even 20 years later. BIOLOGICAL SIGNIFICANCE: Increased complement system activation has been found in the sera of women affected by GCDB who developed a breast cancer, even twenty or more years later. C3f may predict an increased breast cancer risk in the healthy population and in women affected by predisposing conditions.

RESUMO

We previously demonstrated that high serum enterolactone levels are associated with a reduced incidence of breast cancer in healthy women. The present study was aimed at investigating whether a similar association might be found between serum enterolactone levels and the mortality of women with early breast cancer. The levels of enterolactone in cryopreserved serum aliquots obtained from 300 patients, operated on for breast cancer, were measured using a time-resolved fluoro-immunoassay. Levels were analyzed in respect to the risk of mortality following surgery. Cox proportional hazard regression models were used to check for prognostic features, to estimate hazard ratios for group comparisons and to test for the interaction on mortality hazards between the variables and enterolactone concentrations. The Fine and Gray competing risk proportional hazard regression model was used to predict the probabilities of breast cancer-related and breast cancer-unrelated mortalities. At a median follow-up time of 23 years (range 0.6-26.1), 180 patients died, 112 of whom died due to breast cancer-related events. An association between a decreased mortality risk and enterolactone levels ≥ 10 nmol/l was found in respect to both all-cause and breast cancer-specific mortality. The difference in mortality hazards was statistically significant, but it appeared to decrease and to lose significance after the first 10 years, though competing risk analysis showed that breast cancer-related mortality risk remained constantly lower in those patients with higher enterolactone levels. Our findings are consistent with those of most recent literature and provide further evidence that mammalian lignans might play an important role in reducing all-cause and cancer-specific mortality of the patients operated on for breast cancer.

RESUMO

First, to evaluate whether the benefits of combined chemotherapy (CT) and Tamoxifen (T), previously documented in the GROCTA-01 Trial, were long-lasting and, second, to show whether ER or PgR levels could allow the identification of the patients who could benefit from T alone. 504 node-positive, ER-positive, women were randomly assigned to ten CT courses or to 5 years of T or to the combination of the two (CTT). Disease-free (DFS) and overall survival (OS) were the primary trial-endpoints. DFS data were updated in 75% of the patients and S data in 95% of them. Cox regression models were used to check for prognostic features to estimate hazard ratios for treatment comparisons and to test for possible interaction between variables and treatment effects. Interactions between treatments and ER or PgR median levels were studied with the sub-population treatment effect pattern plot (STEPP) methodology. After a median follow-up time of 21 years, the DFS and OS benefits, previously favouring T over CT, continued to be observed, even though they were more evident in the first 6-7 years. The CTT advantages of DFS and OS over T alone were also confirmed. However, the additional benefit was limited to the first 10-12 years as S curves crossed over afterwards. After STEPP analysis, neither ER nor PgR concentrations fully discriminated the patients who could benefit from T alone. Even after such a long follow-up time, we have demonstrated that T is an effective alternative to CT for node-positive, ER-positive, breast cancer patients, regardless of their actual menopausal status, and that the additional benefit, especially on late survival, provided by the addition of CT to this anti-oestrogen, was minimal.

RESUMO

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.

RESUMO

OBJECTIVES: Biological markers that reliably predict clinical and pathological response to primary systemic therapy may have considerable clinical potential; this study evaluated response compared to expression of ER, PgR and Her2, grading and Ki-67 proliferation index before and after neoadjuvant chemotherapy in patients with locally advanced breast cancer (LABC). PATIENTS AND METHODS: Fifty-five patients received neoadjuvant chemotherapy for LABC. The incidence of clinical and pathological responses was assessed with respect to basal clinical stage, absent/low vs. high ER and PgR status, low vs. high proliferation index, grading and Her2 overexpression. RESULTS: Overall, 30 patients (54%) underwent downstaging of their primary tumor; pathological complete remission was observed in only one patient with Her2 positive breast tumor. Patients with pre-treatment Ki-67 >20%, Her2 overexpression, T2b/T3 vs. T4 clinical stage achieved higher response rate. CONCLUSION: The future of neoadjuvant therapy lies in tailoring treatment to individual patients by identifying response predictors; although the number of patients reported is small, this study confirms that clinical stage at diagnosis, Ki-67 reduction and Her2 overexpression are predictive of tumor response to neoadjuvant regimens.

RESUMO

Lignans are natural plant compounds with estrogenic properties and are probably the most important source of phytoestrogens in western diets. They have been suggested to have anticarcinogenic potential. For an evaluation of the effect of these compounds, namely enterolactone, on breast cancer risk, we have reviewed the literature available on major epidemiological studies. We analyzed methodological issues, the design and results of 3 studies providing data on enterolactone dietary intake, 3 studies on urinary excretion and 4 studies concerning blood measurements of enterolactone. All studies on dietary intake were retrospective and based on questionnaires. Two studies showed a significant inverse relationship between dietary lignans consumption and breast cancer incidence, specifically in premenopausal women. No effect was evident in the third study. Among the urinary enterolactone excretion studies, two studies (one retrospective, the other prospective) showed a definite protective effect. However, one retrospective study failed to show any significant interaction. Again, conflicting results were obtained from enterolactone blood measurement studies: two studies demonstrated a protective effect due to enterolactone in premenopausal women, while the other two studies failed to demonstrate any association. In summary, epidemiological evidence to date is conflicting. Prospective large scale studies will require assessing the consumption of antibiotics and dietary habits during adolescence in order to obtain definitive conclusions.

RESUMO

INTRODUCTION: The HER2/neu proto-oncogene encodes a transmembrane receptor protein involved in the development and progression of the majority of cancers. Prior studies have shown that HER2/neu oncogene is overexpressed in approximately 15-30% of ovarian carcinomas. However findings regarding the overexpression and prognosis are still conflicting. METHODS: Our retrospective study was performed on 194 ovarian carcinoma tissues obtained at the time of first surgery. The staining procedure for HER2/neu overexpression was performed using a polyclonal antibody. RESULTS: HER2/neu overexpression was found in 53 out of 194 (27.3%) investigated cases of which 26 (13.4%) carcinomas were weakly positive (score 1+) and 27 (13.9%) moderately (score 2+) to intensely positive (score 3+). No significant relationship was found between HER2/neu score and main clinical and pathological features. Significant difference in overall survival was evident between negative women (0/1+) and positive women (2+/3+): 48 and 29 months, respectively (p = 0.04). In multivariate analysis HER2/neu overexpression appeared to be the only variable significantly correlated with progression and death. CA125 normalization at 3 and 6 months appeared a strong predictor of progression and survival. CONCLUSION: In this study HER2/neu overexpression was associated with an increased risk of progression and death, especially among women with FIGO Stage I and II ovarian carcinoma.

RESUMO

PURPOSE: Tamoxifen, which is actually the gold standard adjuvant treatment in estrogen receptor-positive early breast cancer, is associated with an increased risk of endometrial cancer and other life-threatening events. Moreover, many women relapse during or after tamoxifen therapy because of the development of resistance. Therefore new approaches are required. PATIENTS AND METHODS: We conducted a prospective randomized trial to test the efficacy of switching postmenopausal patients who were already receiving tamoxifen to the aromatase inhibitor anastrozole. After 2 to 3 years of tamoxifen treatment, patients were randomly assigned either to receive anastrozole 1 mg/d or to continue receiving tamoxifen 20 mg/d, for a total duration of treatment of 5 years. Disease-free survival was the primary end point. Event-free survival, overall survival, and safety were secondary end points. RESULTS: Four hundred forty-eight patients were enrolled. All women had node-positive, estrogen receptor-positive tumors. At a median follow-up time of 36 months, 45 events had been reported in the tamoxifen group compared with 17 events in the anastrozole group (P = .0002). Disease-free and local recurrence-free survival were also significantly longer in the anastrozole group (hazard ratio [HR] = 0.35; 95% CI, 0.18 to 0.68; P = .001 and HR = 0.15; 95% CI, 0.03 to 0.65; P = .003, respectively). Overall, more adverse events were recorded in the anastrozole group compared with the tamoxifen group (203 v 150, respectively; P = .04). However, more events were life threatening or required hospitalization in the tamoxifen group than in the anastrozole group (33 of 150 events v 28 of 203 events, P = .04). CONCLUSION: Switching to anastrozole after the first 2 to 3 years of treatment is well tolerated and significantly improves event-free and recurrence-free survival in postmenopausal patients with early breast cancer.
