Superficial spreading melanoma (SSM) and nodular melanoma (NM) are the most common melanoma histologic subtypes and are characterized by different biological features. We retrospectively analyzed all consecutive patients with advanced melanoma, treated with anti-PD-1 and/or anti-CTLA-4 at our center, with data available on primary tumor subtype. The primary objective was to assess the association between histologic subtype and patients' outcomes. In addition, we analyzed whole-exome and whole-transcriptome sequencing data of a cohort of advanced melanoma to identify genes and related pathways, characterized by significant differences between NMs and SSMs. Twenty-one patients with NM and 39 with SSM, treated with anti-PD-1(53/60) as monotherapy or combined with anti-CTLA-4 (7/60), were analyzed. All known clinical-pathologic prognostic factors were well balanced between NM and SSM groups, except for the ECOG-PS score. The overall response rate was 52.4% (95% confidence interval, 29.8-74.3) in the NMs group versus 20.5% (9.3-36.5) in the SSMs group (P-value=0.02). The median progression-free survival and overall survival were, respectively, 13.9 and 44.5 months in the NMs group versus only 3.2 and 12 months in SSMs group (progression-free survival P-value=0.032; overall survival P-value=0.002). Multivariable analysis adjusting for the ECOG-PS, confirmed similar results. Whole-exome and whole-transcriptome data of 28 NMs and 21 SSMs were analyzed. No significant differences were observed in terms of both TMB and frequency of mutation in any gene. A total of 266 genes were overexpressed in NMs as compared with SSMs, and enrichment-analysis revealed a significant enrichment (false discovery rate

The Barcelona clinic liver cancer (BCLC) algorithm is the most widely accepted staging system form hepatocellular carcinoma (HCC). Liver resection is traditionally proposed to early stage HCC (BCLC-0/A), even if recent reports have shown that surgical resection could provide a safe and effective treatment also for intermediate-stage HCC (BCLC-B). In this study, we focused on surgical and oncological outcomes of hepatic resection in BLCB-B patients. Patients who received hepatic resection for early- (BCLC-0/A) or intermediate-stage (BCLC-B) HCC in two tertiary hepatobiliary centers between January 2003 and December 2016 were included in study. Four-hundred and twenty-nine patients were included in the analysis. At the time of resection, 298 patients were classified as BCLC-A/0 and 131 as BCLC-B. Despite a higher complication rate in BCLC-B group (49.6% vs 32.9%; p = 0.001), the incidence of clinically relevant complications did not differ significantly between the two groups (16.0% vs 10.1%; p = 0.079); moreover, postoperative mortality (4.6% vs 2.7%; p = 0.309) and relapse-free survival (RFS) were similar between BCLC-0/A and BCLC-B group (1-, 3-, and 5-year RFS: 74, 43, and 31% vs 59, 38, and 34%; p = 0.180). Overall survival was slightly worse in BCLC-B group (1-, 3-, and 5-year overall survival of 89, 70, and 52% vs. 77, 51, and 44%; p = 0.004). Focusing on BCLC-B group, a Child–Pugh score B (HR 2.47; p = 0.003), growing number of nodules (HR 3.04; p = 0.003), and R1 resection (HR 2.43; p = 0.005) beard a higher risk of tumor recurrence, while overall survival was negatively affected by the presence of more than two nodules (HR 3.66; p = 0.0001) and R1 resection (HR 3.06; p = 0.0001); patients presenting single-large HCC experienced a better overall survival (HR 0.53; p = 0.014) and lower recurrence-rate (HR 0.60; p = 0.046). Hepatic resection for intermediate-stage HCC shows acceptable results in terms of perioperative morbidity and mortality, with better oncological outcomes in patients with lower number of lesions despite of their size.

Introduction Only a limited number of meta-analyses providing risk curve functions of dose-response relationships between various smoking-related variables and cancer-specific risk are available. Methods and analysis To identify all relevant original publications on the issue, we will conduct a series of comprehensive systematic reviews based on three subsequent literature searches: (1) an umbrella review, to identify meta-analyses, pooled analyses and systematic reviews published before 28 April 2017 on the association between cigarette smoking and the risk of 28 (namely all) malignant neoplasms; (2) for each cancer site, an updated review of original publications on the association between cigarette smoking and cancer risk, starting from the last available comprehensive review identified through the umbrella review; and (3) a review of all original articles on the association between cigarette smoking and site-specific cancer risk included in the publications identified through the umbrella review and the updated reviews. The primary outcomes of interest will be (1) the excess incidence/mortality of various cancers for smokers compared with never smokers; and (2) the dose-response curves describing the association between smoking intensity, duration and time since stopping and incidence/mortality for various cancers. For each cancer site, we will perform a meta-analysis by pooling study-specific estimates for smoking status. We will also estimate the dose-response curves for other smoking-related variables through random-effects meta-regression models based on a non-linear dose-response relationship framework. Ethics and dissemination Ethics approval is not required for this study. Main results will be published in peer-reviewed journals and will also be included in a publicly available website. We will provide therefore the most complete and updated estimates on the association between various measures of cigarette smoking and site-specific cancer risk. This will allow us to obtain precise estimates on the cancer burden attributable to cigarette smoking. Trial registration number This protocol was registered in the International Prospective Register of Systematic Reviews (CRD42017063991).

Aim: The primary aim of the study was to assess the association between risk of recurrence and HER2 equivocal gene status through immunohistochemistry in patients with early breast cancer. Patients and Methods: We retrospectively analyzed clinical and pathological data of 455 consecutive patients with early breast cancer (BC) who were HER2+ and had a HER2/CEP17 ratio

Purpose Oncoplastic surgery is a well-established discipline that combines conserving treatment for breast cancer with immediate plastic reconstruction. Although widely practiced, the oncologic outcomes of this combined approach are reported only in small series. The aim of the present paper is to assess the safety of oncoplastic surgery for invasive primary breast cancer. Methods We compared 454 consecutive patients who underwent an oncoplastic approach between 2000 and 2008 for primary invasive breast tumors (study group) with twice the number of patients who received conservation alone in the same interval time (control group). Disease free survival and overall survival were estimated using the Kaplan-Meier method. The log-rank test was used to assess differences between groups. Results The median follow-up was 7.2 years. The overall survival is similar within the two groups, being 91.4% and 91.3% at 10-yr in the study group and in the control group respectively. The disease free survival is slightly lower in the oncoplastic group (69 vs.73.1% at 10-yr). The difference is not statistically significant. Discussion. We have compared a large series of primary breast cancer patients that have undergone oncoplastic surgery (454) with a control group (908) and they were followed for a prolonged period of time. It provides the best available evidence to suggest that oncoplastic surgery is a safe and reliable treatment option for the managing of invasive breast cancer.

Background/Aim: In breast cancer (BC) patients, breast surgery followed by immediate breast reconstruction (IBR) might favour recurrences and metastases due to extensive surgical manipulation. We retrospectively investigated whether IBR after mastectomy and neoadjuvant chemotherapy (NT) influenced the outcome in patients with early and locally advanced oestrogen receptor (ER)-negative BC. Patients and Methods: Between 1995 and 2006, 133 BC patients received NT followed by total mastectomy, 59 of whom underwent IBR. Patients receiving IBR (IBR group) were compared to patients who did not receive IBR (no-IBR group) over a prolonged median follow-up time (8.2 years). Results: Patients receiving IBR were on average younger than patients not receiving IBR (p

The observational evaluation of alcoholics' treatments requires a combined analysis of alco- holic behaviour during treatment and of adherence to therapeutic programmes. The application of survival analysis techniques in this setting has been explored in this study. Two hundred and seventy alcoholics admitted to 15 Italian treatment units in a 1-year period were followed-up for 2 years, recording date and length of every recurrence episode and of definitive or transitory interruption of the planned treatment. An extensive use of several survival analysis techniques was made. The length of time between the start of the treatment and the first episode of relapse did not give a reliable measure of frequency of failures. Conversely, the length of time between the start of treatment and withdrawal appeared to be unbiased. The cumulative proportions of treatment-compliant patients (and the corresponding 95% confidence intervals) were 71% (66-76%), 63% (57-69%) and 53% (47-60%) after 6 months, 1 year and 2 years respectively from the start of treatment. Cumulative abstinence duration before withdrawal was significantly and positively associated with the risk of first, of definitive, and of every episode of treatment interruption. This first application of survival analysis techniques to the combined study of alcoholic behaviour and of adherence to treatment can improve our knowledge of treatment evaluation. Our results suggest that com- pliance to treatment is an objective and versatile outcome measure. Long-term follow-up studies aimed to elucidate the determinants of withdrawal should be performed.

Background: Patients with advanced type B3 thymoma and thymic carcinoma resistant to chemotherapy have few treatment options. We report the efficacy and safety results of the combination of the anti-PD-L1 inhibitor avelumab with the anti-angiogenesis drug axitinib in patients with advanced type B3 thymoma and thymic carcinoma. Methods: CAVEATT was a single-arm, multicentre, phase 2 trial, conducted in two Italian centres (the European Instituteof Oncology and the Humanitas Institute, Milan) in patients with histologically confirmed type B3 thymoma or thymic carcinoma, with advanced stage of disease who had progressed after at least one line of platinum-based chemotherapy. Previous treatment with an anti-angiogenesis drug was allowed but not with immune checkpoint inhibitors. Other inclusion criteria were age 18 years or older, an Eastern Cooperative Oncology Group performance status of 0–2, progressive disease, and presence of measurable disease according to Response Evaluation Criteria In Solid Tumours (RECIST) version 1.1. Patients received avelumab 10 mg/kg intravenously every 2 weeks and axitinib 5 mg orally twice daily until disease progression or unacceptable toxicity. The primary endpoint was the centrally assessed overall response rate according to RECIST version 1.1. Patients who received at least one cycle of treatment and had at least one CT scan after treatment start at scheduled time point by protocol were judged assessable for response and were included in efficacy and safety analyses. This study is registered with EUDRACT, 2017–004048–38; enrolment is completed and follow-up is ongoing. Findings: Between April 22, 2019, and June 30, 2021, 32 patients were enrolled. 27 patients had a thymic carcinoma, three a type B3 thymoma, and two a mixed type B3 thymoma and thymic carcinoma. 29 (91%) of 32 patients had stage IVB disease and 13 (41%) of 32 had been pretreated with an anti-angiogenesis drug. 11 of 32 patients had an overall response; thus the overall response rate was 34% (90% CI 21–50); no patients had a complete response, 11 (34%) had a partial response, 18 (56%) had stable disease, and in two patients (6%) progressive disease was the best response. The most common grade 3 or 4 adverse event was hypertension (grade 3 in six [19%] of 32 patients). Four (12%) of 32 patients developed serious adverse events that were new-onset immune-related adverse events, including one grade 3 interstitial pneumonitis, one grade 4 polymyositis, and two grade 3 polymyositis. There were no treatment-related deaths. Interpretation: Avelumab combined with axitinib has promising anti-tumour activity and acceptable toxicity in patients with advanced type B3 thymoma and thymic carcinoma progressing after chemotherapy, and could emerge as a new standard treatment option in this setting.

Background: Alcohol is capable of traversing the blood-brain barrier and is thus a possible risk factor for brain cancer. Several epidemiological studies have been published on the issue, a number of those during recent years, with inconsistent findings. Materials and methods: We performed a systematic literature search in the Medline and EMBASE databases. We found a total of 19 studies providing risk estimates for total alcohol or specific alcoholic beverages. Pooled estimates of the relative risks (RR) and 95% confidence intervals (CI) were calculated using random-effects models. Results: The pooled RR of brain cancer for alcohol drinkers versus non-drinkers was 0.97 (95% CI 0.82-1.15; based on 12 studies). Moderate (

Epub 2012 Mar 7.; International audience; BACKGROUND: The role of alcohol consumption in relation with renal cell carcinoma is still unclear; a few studies have reported a beneficial effect of moderate levels of alcohol consumption, whereas it remains still under debate whether there is a dose-response association. MATERIALS AND METHODS: Twenty observational studies (4 cohort, 1 pooled and 15 case-control) reporting results on at least three levels of alcohol consumption were selected through a combined search with PubMed and EMBASE of articles published before November 2010. Overall relative risks (RRs) and 95% confidence intervals (CIs) were estimated using random-effects models, and both second-order fractional polynomials and random effect meta-regression models were implemented for the study of dose-risk relation. RESULTS: The estimated RRs were 0.85 (95% CI: 0.80-0.92) for any alcohol drinking, 0.90 (95% CI: 0.83-0.97) for light drinking (0.01-12.49 g/day), 0.79 (95% CI: 0.71-0.88) for moderate drinking (12.5-49.9 g/day) and 0.89 (95% CI: 0.58-1.39) for heavy drinking (>/=50 g/day), respectively. CONCLUSION: Our meta-analysis supports the hypothesis of a negative effect of moderate alcohol consumption on the risk of renal cell cancer.

Epub 2011 Oct 29.; International audience; BACKGROUND: We aimed at investigating the risk of bladder cancer at different levels of alcohol consumption by conducting a meta-analysis of epidemiological studies. PATIENTS AND METHODS: In October 2010, we carried out a systematic literature search in the Medline database, using PubMed. We identified 16 case-control and 3 cohort studies, including a total of 11 219 cases of bladder cancer, satisfying the inclusion criteria for this meta-analysis. Moderate alcohol intake was defined as /=3 drinks/day. Pooled estimates of the relative risks (RR) and the corresponding 95% confidence intervals (CI) were calculated using random effects models. RESULTS: Compared with non-drinkers, the pooled RRs of bladder cancer were 1.00 (95% CI 0.92-1.09) for moderate and 1.02 (95% CI 0.78-1.33) for heavy alcohol drinkers. When we excluded four studies that did not adjust for tobacco smoking, the corresponding estimates were 0.98 (95% CI 0.89-1.07) and 0.97 (95% CI 0.72-1.31). CONCLUSIONS: This meta-analysis of epidemiological studies provides definite evidence on the absence of any material association between alcohol drinking and bladder cancer risk, even at high levels of consumption.

Background: The role of alcohol consumption as an independent risk factor for lung cancer is controversial. Since drinking and smoking are strongly associated, residual confounding by smoking may bias the estimation of alcohol consumption and lung cancer risk relation. Therefore, we undertook a meta-analysis to quantitatively assess the association between alcohol and risk of lung cancer in never smokers.Methods: After a literature search in Medline, we included all case-control and cohort studies published up to January 2010 that reported an estimate of the association between alcohol intake and lung cancer risk in never smokers.Results: We selected 10 articles, including 1913 never smoker lung cancer cases. The random-effects pooled relative risk (RR) for drinkers versus nondrinkers was 1.21 [95% confidence interval (CI) 0.95-1.55]. The same figure was 1.05 (95% CI 0.89-1.23) after the exclusion of one outlier study. At the dose-response analysis, RR for an increase in alcohol intake of 10 g/day was 1.01 (95% CI 0.92-1.10).Conclusions: Alcohol consumption was not associated with lung cancer risk in never smokers. Even if the synergistic effect of smoking and alcohol cannot be ruled out, our results suggest that alcohol does not play an independent role in lung cancer etiology. © The Author 2011.

Background: The International Agency for Research on Cancer (IARC) concluded that alcohol consumption is related to colorectal cancer (CRC). However, several issues remain unresolved, including quantification of the association for light (=1 drink/day) and moderate (2-3 drinks/day) alcohol drinking, investigation of the dose-response relationship, and potential heterogeneity of effects by sex, colorectal site, and geographical region. Methods: Twenty-seven cohort and 34 case-control studies presenting results for at least three categories of alcohol intake were identified from a PubMed search of articles published before May 2010. The summary relative risks (RRs) were estimated by the random effects model. Second-order fractional polynomials and random effects metaregression models were used for modeling the dose-risk relation. Results: The RRs were 1.21 [95% confidence interval (CI) 1.13-1.28] for moderate and 1.52 (95% CI 1.27-1.81) for heavy (=4 drinks/day) alcohol drinking. The RR for moderate drinkers, compared with non-/occasional drinkers, was stronger for men (RR = 1.24, 95% CI 1.13-1.37) than for women (RR = 1.08, 95% CI 1.03-1.13; Pheterogeneity = 0.02). For heavy drinkers, the association was stronger in Asian studies (RR = 1.81, 95% CI 1.33-2.46; Pheterogeneity = 0.04). The dose-risk analysis estimated RRs of 1.07 (95% CI 1.04-1.10), 1.38 (95% CI 1.28-1.50), and 1.82 (95% CI 1.41-2.35) for 10, 50, and 100 g/day of alcohol, respectively. Conclusions: This meta-analysis provides strong evidence for an association between alcohol drinking of >1 drink/day and colorectal cancer risk. © The Author 2011.

Quantification of the association between alcohol drinking and risk of esophageal squamous cell carcinoma (ESCC) is an open issue, particularly among light alcohol drinkers, never-smokers, and Asian populations, in which some high-risk polymorphisms in alcohol metabolizing genes are more prevalent. To address these issues, we conducted a systematic review and meta-analysis using 40 case-control and 13 cohort studies that reported on the risk associated with alcohol drinking for at least three levels of consumption. In studies adjusted for age, sex, and tobacco smoking, the relative risk (RR) and 95% confidence interval (CI) for the association between light alcohol drinking (=12.5 g/d) and risk of ESCC was 1.38 (1.14-1.67). The association was slightly stronger in Asian countries than in other populations. The adjusted RRs (95% CIs) were 2.62 (2.07-3.31) for moderate drinking (>12.5->50 g/d) and 5.54 (3.92-7.28) for high alcohol intake (=50 g/d); the RRs were slightly higher in non-Asian populations. In prospective studies, the RR (95% CI) was 1.35 (0.92-1.98) for light, 2.15 (1.55-2.98) for moderate, and 3.35 (2.06-5.46) for high alcohol intakes; light drinking showed an association with ESCC in Asia (five studies) but not in other regions (three studies). Among never-smokers (nine studies), the RR (95% CI) was 0.74 (0.47-1.16) for light, 1.54 (1.09-2.17) for moderate, and 3.09 (1.75-5.46) for high intakes. This meta-analysis further corroborates the association of moderate and high alcohol intake with risk of ESCC and provides risk estimates based on multiple prospective studies. Light alcohol intake appears to be associated to ESCC mainly in studies in Asia, which suggests a possible role of genetic susceptibility factors. © 2011 UICC.

Background: We retrospectively investigated the role of (neo)adjuvant chemotherapy in patients with primary, localized angiosarcoma. Methods: We selected all patients with primary, localized angiosarcoma, who had received radical surgery between January 2005 and December 2019 at 33 European sarcoma reference centers. The primary objective was to compare the outcome of patients who received (neo)adjuvant chemotherapy versus those who did not, in terms of overall survival (OS), disease-free survival (DFS) and distant metastasis-free survival (DMFS). To reduce the risk of confounding due to imbalance, a propensity-score matching(PSM) was performed. Finally, subgroups analysis was performed according to tumor site, tumor size (< 50 mm or ≥ 50 mm) and patients predicted 10-years OS according to the nomogram sarculator (two different cutoff-values were applied: ≤ 33% or > 33% and < 60% or ≥ 60%). Results: 362 patients were analyzed: 149 (41.2%; treated group) received (neo) adjuvant chemotherapy and 213 (58.6%; control group) did not. The median follow-up for the OS endpoint was 5.1 years (95% CI: 4.0–5.5). The OS-HR was 0.58 (95%CI: 0.40–0.83; p-value = 0.003) in the univariate analysis and 0.74 (95% CI: 0.38–1.43; p = 0.367) in the PSM analysis. The DFS-HR was 0.75 (95% CI: 0.57–0.98; p-value = 0.036) in the univariate analysis, and 0.91 (95% CI:0.56–1.48; p-value = 0.7) in the PSM analysis. The DMFS-HR was 0.75 (95% CI: 0.55–1.02; p-value = 0.065) in univariate analysis and 0.92 (95% CI: 0.53–1.61; p-value = 0.769) in the PSM analysis. Subgroup analysis revealed no heterogeneity of results in strata of tumor site. On the contrary, there was a trend for heterogeneity according to tumor size and patient's risk of death. For all the endpoints analyzed, patients with tumors smaller than 50 mm or at lower risk of death seem to have no benefit from chemotherapy, while patients with larger tumors or at higher risk of death at 10 years seem to derive substantial benefit. Conclusion: This large, retrospective study suggests that patients affected by > 50 mm and/or high-risk primary, localized angiosarcoma could benefit from (neo)adjuvant chemotherapy.

BACKGROUND AND PURPOSE: Diversity, Equity and Inclusion (DEI) in the medical workforce is linked to improved patient care and innovation, as well as employee retention and engagement. The European Society for Radiotherapy and Oncology launched a survey to provide a benchmark of DEI and engagement among radiation oncology (RO) professionals in Europe.METHODS: An anonymous survey was disseminated among RO professionals in Europe. The survey collected demographics and professional information, and participants were asked if they felt they belonged to a minority group. A DEI and workforce engagement questionnaire by Person et al. evaluated 8 inclusion factors. A favourable score was calculated by adding the percentage of "strongly agreed" or "agreed" answers.RESULTS: A total of 812 complete responses were received from 35 European countries. 21% of respondents felt they belonged to a minority group, mostly based on race/ethnicity (5.9%), nationality (4.8%) and age (4.3%). Compared to benchmark data from the United States, scores were lower for most inclusion factors, and to a greater extent for minority groups. The overall favourable score was 58% for those belonging to a minority group, significantly lower than for other respondents (71%, pCONCLUSIONS: Our work indicates that actions to improve DEI and workforce engagement among RO professionals in Europe are urgently needed, in particular among minority groups. This would potentially improve employee wellbeing and retention, promoting high quality care and innovation.

Several studies suggest an inverse relation between coffee drinking and risk of hepatocellular carcinoma (HCC). We conducted a meta-analysis of published studies on HCC that included quantitative information on coffee consumption. Ten studies were retrieved (2,260 HCC cases), including 6 case–control studies from southern Europe and Japan (1551 cases) and 4 cohort studies from Japan (709 cases). The summary relative risk (RR) for coffee drinkers versus non-drinkers was 0.54 (95% confidence interval [CI] 0.38-0.76) for case–control studies and 0.64 (95% CI 0.56-0.74) for cohort studies. The overall RR was 0.59 (95% CI 0.49-0.72), with significant heterogeneity between studies. The overall summary RR for low or moderate coffee drinkers was 0.70 (95% CI 0.57-0.85), and that for high drinkers was 0.45 (95% CI 0.38-0.53). The summary RR for an increase of 1 cup of coffee per day was 0.77 (95% CI 0.72-0.83) from case–control studies, 0.75 (95% CI 0.65-0.85) from cohort studies, and 0.77 (95% CI 0.72-0.82) overall. The consistency of an inverse relation between coffee drinking and HCC across study design and geographic areas weighs against a major role of bias or confounding. Coffee drinking has also been related to reduced risk of other liver diseases, thus suggesting a continuum of the favorable effect of coffee on liver function. However, subjects with liver conditions may selectively reduce their coffee consumption. Conclusion: The present analysis provides evidence that the inverse relation between coffee and HCC is real, though inference on causality remains open to discussion. (HEPATOLOGY 2007.)

Purpose The purpose of the study was to evaluate the toxicity, local control, overall and disease-free survival of elderly breast cancer (BC) patients treated with adjuvant once-weekly ultra-hypofractionated radiotherapy (RT) either with intensity-modulated RT (IMRT) or 3D conformal RT (3DCRT). Methods From July 2011 to July 2018, BC patients receiving 5.7 Gy once a week for 5 weeks to the whole breast after breast-conserving surgery were considered for the study. Inclusion criteria were: T1–T3 invasive BC, no or limited axillary involvement, age ≥ 65 years or women with commuting difficulties or disabling diseases. Results A total of 271 patients were included in the study. Median age was 76 (46–86) years. Most of BC were T1 (77%), while the remaining were T2 (22.2%) and T3 (0.4%). Axillary status was negative in 68.3% of the patients. The only severe acute toxicity (G3) at the end of RT was erythema (0.4%), registered in the 3DCRT group; no G3 edema or epitheliolysis was recorded. With 18 months of median follow-up, severe early–late toxicity (G3) was reported in terms of fibrosis and breast retraction, both with an incidence of 1.4%, mostly in the 3DCRT group. Oncological outcomes at a median follow-up of 2.9 years reported 249/271 (91.9%) patients alive and free from any event and 5 (1.8%) isolated locoregional recurrences. At 3 years, disease-free survival and overall survival were 94.9% and 97.8%, respectively. Breast volume > 500 cm3 was reported as predictive for moderate–severe (≥ G2) acute toxicity. Conclusions Weekly ultra-hypofractionated whole breast RT seems feasible and effective. Toxicity was mild, local control was acceptable, and overall survival was 97.8% at 3 years. Rates of severe toxicity were reduced with the IMRT technique. Supplementary Information The online version contains supplementary material available at 10.1007/s00432-021-03907-w.

Despite several studies support a positive association between heavy alcohol consumption and liver cancer risk, a consistent dose-risk relationship has not yet been established. We carried out a systematic review and a meta-analysis of the association between alcohol intake and liver cancer occurrence, following the Meta-analysis Of Observational Studies in Epidemiology guidelines. We searched for cohort and nested case-control studies on the general population published before April 2013, using PubMed and EMBASE. Summary meta-analytic relative risks (RRs) were estimated using random-effect models. We included 16 articles (19 cohorts) for a total of 4445 incident cases and 5550 deaths from liver cancer. Compared with non-drinking, the pooled RRs were 0.91 (95% confidence interval, CI, 0.81-1.02) for moderate drinking (

The association between alcohol and leukemia risk has been addressed in several studies in the past two decades, but results have been inconsistent. Therefore, we conducted a systematic review and meta-analysis to quantify the dose-risk relation. Through the literature search up to August 2013, we identified 18 studies, 10 case-control and 8 cohorts, carried out in a total of 7142 leukemia cases. We derived pooled meta-analytic estimates using random-effects models, taking into account the correlation between estimates, and we performed a dose-risk analysis using a class of nonlinear random-effects meta-regression models. Stratified analyses were carried out on leukemia subtypes and groups, in order to identify possible etiologic differences. Compared with nondrinkers, the relative risks (RRs) for all leukemia were 0.94 [95% confidence interval (CI), 0.85-1.03], 0.90 (95% CI, 0.80-1.01) and 0.91 (95% CI, 0.81-1.02) for any, light (=1 drink/day) and moderate to heavy (>1 drink/day) alcohol drinking, respectively. The summary RRs for any alcohol drinking were 1.47 (95% CI, 0.47-4.62) for acute lymphoblastic leukemia, 0.94 (95% CI 0.77-1.15) for chronic lymphocytic leukemia, 1.02 (95% CI, 0.86-1.21) for acute myeloid leukemia and 0.93 (95% CI 0.75-1.14) for chronic myeloid leukemia. The subgroup analysis on geographical area for all leukemia combined showed RRs of 0.84 (95% CI, 0.76-0.93), 0.92 (95% CI, 0.83-1.01) and 1.32 (95% CI, 1.02-1.70) for studies conducted in America, Europe and Asia, respectively. We did not find an increased risk of leukemia among alcohol drinkers. If any, a modest favorable effect emerged for light alcohol drinking, with a model-based risk reduction of approximately 10% in regular drinkers. © 2014 Elsevier Ltd.

It has been suggested that alcohol intake increases sunburn severity, a major risk factor for cutaneous melanoma (CM). Several epidemiological studies have investigated the relationship between alcohol consumption and CM, but the evidence is inconsistent. Therefore, we aimed to quantify this relationship better, using a meta-analytical approach. The dose-risk relationship was also modelled through a class of flexible nonlinear meta-regression random effects models. The present meta-analysis included 16 studies (14 case-control and two cohort investigations) with a total of 6251 cases of CM. The pooled relative risk (RR) for any alcohol drinking compared with no/occasional drinking was 1·20 [95% confidence interval (CI) 1·06-1·37]. The risk estimate was similar in case-control (RR 1·20, 95% CI 1·01-1·44) and cohort studies (RR 1·26, 95% CI 1·19-1·35). The pooled RR was 1·10 (95% CI 0·96-1·26) for light alcohol drinking (≤ 1 drink per day) and 1·18 (95% CI 1·01-1·40) for moderate-to-heavy drinking. The pooled RR from 10 studies adjusting for sun exposure was 1·15 (95% CI 0·94-1·41), while the RR from six unadjusted studies was 1·27 (95% CI 1·20-1·35). No evidence of publication bias was detected. This meta-analysis of published data reveals that alcohol consumption is positively associated with the risk of CM. However, caution in interpreting these results is required, as residual confounding by sun exposure cannot be ruled out. What's already known about this topic? Alcohol drinking increases sunburn severity, a major risk factor for cutaneous melanoma. Several epidemiological studies have investigated the relationship between alcohol consumption and cutaneous melanoma, but the evidence is inconsistent. What does this study add? We found a 20% increased risk of cutaneous melanoma with regular alcohol drinking. © 2014 British Association of Dermatologists.

The role of alcohol intake in the risk for multiple myeloma (MM) is unclear, although some recent findings suggest an inverse relationship. To summarize the information on the topic, we carried out a systematic review and a dose-risk meta-analysis of published data. Through the literature search until August 2013, we identified 18 studies, eight case-control and 10 cohort studies, carried out in a total of 5694 MM patients. We derived pooled meta-analytic estimates using random-effects models, taking into account the correlation between estimates, and we carried out a dose-risk analysis using a class of nonlinear random-effects meta-regression models. The relative risk for alcohol drinkers versus non/occasional drinkers was 0.97 [95% confidence interval (CI), 0.85-1.10] overall, 0.96 (95% CI, 0.74-1.24) among case-control studies, and 1.00 (95% CI, 0.89-1.13) among cohort studies. Compared with nondrinkers, the pooled relative risks were 0.96 (95% CI, 0.81-1.13) for light (i.e. ≤1 drink/day) and 0.89 (95% CI, 0.74-1.07) for moderate-to-heavy (i.e. >1 drink/day) alcohol drinkers. The dose-risk analysis revealed a model-based MM risk reduction of about 15% at two to four drinks/day (i.e. 25-50 g of ethanol). The present meta-analysis of published data found no strong association between alcohol drinking and MM risk, although a modest favorable effect emerged for moderate-to-heavy alcohol drinkers. © 2014 Wolters Kluwer Health | Lippincott Williams & Wilkins.

Background Postmastectomy radiotherapy (PMRT) with TomoHelical™ (TH) or TomoDirect™ (TD) allows a uniform target coverage. In this study, we compare treatment plans using TD and TH in the setting of hypofractionated PMRT and immediate breast reconstruction. Material and methods The TD-treatment plans of breast cancer patients treated between May 2016 and August 2019 were retrospectively selected. All the TD plans were re-planned on TH with the same prescription dose (40.05 Gy/15 fractions) and according to our dose/volume constraints. Data about the 2 treatment plans were compared with a focus on PTV coverage and all the organs at risk (OARs) constraints. Results Fifty patients for a total number of 100 treatment plans (50 with TD and 50 re-planned with TH) were analyzed. All the median value in the TD PTV CHEST WALL plans fulfilled the predefined planning objectives, even though TH emerged as best for target coverage with statistically significant difference for V90%. TD provided the lowest V95% for the PTV SVC, but the median value was near to the recommended value of 90% (89.8 % vs 98.6% for TD and TH, respectively). Overall, TD reached the best OARs sparing. The main statistically significant differences with TH were for contralateral breast, ipsilateral and contralateral lung. All the other dose values for TH were higher than TD, but they fulfilled the recommended/acceptable predefined planning objectives. Conclusions In the setting of PMRT, TD compared to TH reached an acceptable target volume coverage, with an optimal sparing of OARs.

Background Specific data regarding coronavirus disease 2019 (COVID-19) in patients with neuroendocrine neoplasms (NENs) are lacking. The aim of this study is to describe the characteristics of patients with NENs who tested severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) positive. Material and methods This is a worldwide study collecting cases of patients with NENs along with a positive nasopharyngeal swab reverse transcriptase-polymerase chain reaction (RT-PCR) test for SARS-CoV-2 between June 1, 2020, and March 31, 2021. Centres treating patients with NENs were directly contacted by the principal investigator. Patients with NENs of any primary site, grade and stage were included, excluding small-cell lung carcinoma and mixed adenoneuroendocrine carcinoma. Results Among 81 centres directly contacted, 88.8% responded and 48.6% of them declined due to lack of cases or interest. On March 31st, 2021, eight recruiting centres enrolled 89 patients. The median age was 64 years at the time of COVID-19 diagnosis. Most patients had metastatic, non-functioning, low-/intermediate-grade gastroenteropancreatic NENs on treatment with somatostatin analogues and radioligand therapy. Most of them had comorbidities. Only 8% of patients had high-grade NENs and 12% were receiving chemotherapy. Most patients had symptoms or signs of COVID-19, mainly fever and cough. Only 3 patients underwent sub-intensive treatment, whereas most of them received medical therapies, mostly antibiotics. In two third of cases, no changes occurred for the anti-NEN therapy. More than 80% of patients completely recovered without sequelae, whereas 7.8% patients died due to COVID-19. Conclusions Patients included in this study reflect the typical NEN population regardless of SARS-CoV-2. In most cases, they overcome COVID-19 without need of intensive care, short-term sequelae and discontinuation of systemic oncological therapy.

Introduction: We investigated the impact of changes in lifestyle habits on colorectal cancer (CRC) risk in a multi-country European cohort. Methods: We used baseline and follow-up questionnaire data from the EPIC cohort to assess changes in lifestyle habits and their associations with CRC development. We calculated a healthy lifestyle index (HLI) score based on smoking status, alcohol consumption, body mass index and physical activity collected at the two timepoints. HLI ranged from 0 (most unfavourable) to 16 (most favourable). We estimated the association between HLI changes and CRC risk using Cox regression models and reported hazard ratios (HR) with 95% confidence intervals (CI). Results: Among 295,865 participants, 2,799 CRC cases were observed over a median of 7.8 years. Median time between questionnaires was 5.7 years. Each unit increase in HLI from the baseline to the follow-up assessment was associated with a statistically significant 3% lower CRC risk. Among participants in the top tertile at baseline (HLI>11), those in the bottom tertile at follow-up (HLI≤9) had a higher CRC risk (HR 1.34; 95%CI 1.02-1.75) than those remaining in the top tertile. Among individuals in the bottom tertile at baseline, those in the top tertile at follow-up had a lower risk (HR 0.77; 95%CI 0.59-1.00) than those remaining in the bottom tertile. Discussion: Improving adherence to a healthy lifestyle was inversely associated with CRC risk, while worsening adherence was positively associated with CRC risk. These results justify and support recommendations for healthy lifestyle changes and healthy lifestyle maintenance for CRC prevention.

Epub 2012 Sep 4.; International audience; AIMS: To quantify the magnitude of the association between alcohol and oral and pharyngeal cancer (OPC) by sex, smoking habits, type of alcoholic beverage and other factors. METHODS: We combined findings from all case-control and cohort studies published until September 2010 and present in this article the results classified by these factors, using a meta-analytic approach. Summary relative risks (RRs) were obtained using random-effects models; heterogeneity was assessed using the chi(2) test. RESULTS: The association between alcohol and OPC risk was similar in men and women, with similar dose-response relationships. No notable differences were found with respect to geographic area and other factors, both for drinking overall and heavy (>/=4 drinks/day) drinking. Among never/non-current smokers, the pooled RRs were 1.32 (95% confidence interval, CI, 1.05-1.67) for drinking, and 2.54 (95% CI, 1.80-3.58) for heavy drinking. The corresponding RRs in smokers were 2.92 (95% CI, 2.31-3.70) and 6.32 (95% CI, 5.05-7.90). The pooled RRs for any drinking irrespective of smoking were 2.12 (95% CI, 1.37-3.29) for wine-, 2.43 (95% CI, 1.92-3.07) for beer- and 2.30 (95% CI, 1.78-2.98) for spirits-only drinking. The corresponding RRs for heavy drinking were 4.92 (95% CI, 2.80-8.65), 4.20 (95% CI, 1.43-12.38) and 5.20 (95% CI, 2.77-9.78). CONCLUSION: The alcohol-related RRs are similar with respect to sex, geographic area and type of alcoholic beverage. The association between alcohol and OPC is stronger in smokers than in non-smokers.

Background We report here for the first time, a comprehensive characterization of biological and clinical features of early-stage triple negative Invasive Lobular Carcinomas(TN-ILCs) Methods We analyzed all consecutive patients with early-stage TN-ILC operated at two reference cancer-centers between 1994 and 2012. Primary objective was to assess the invasive disease-free survival(iDFS). Co-primary objective was to assess biological features of TN-ILCs, including molecular intrinsic subtypes based on PAM-50 assay, expression of androgen receptor (AR) and mutational status of ERBB2-gene. Additionally, DNA mutational status of an independent cohort of 45 TN-ILCs from three databases were analyzed, to confirm mutations in ERBB2-gene and to identify other recurrently mutated genes. Results Among 4152 ILCs, 74(1.8%) were TN and were analyzed. The iDFS at 5 and 10 years of FUP were 50.4%(95%CI,38.0–61.6) and 37.2%(95%CI,25.5–48.8), respectively. The molecular subtype was defined through PAM50-classifier for 31 out of 74 TN-ILCs: 48% were Luminal-A(15/31), 3% luminal-B(1/31), 32% HER2-enriched (10/31), and only 16% basal-like(5/31). Luminal tumors expressed AR more frequently than non-luminal tumors (AR≥1% in 94% of luminal tumors versus 53% in non-luminal tumors; p-value = 0.001). 20% of TN-ILCs analyzed(7/35), harbored a pathogenetic and actionable mutation in the ERBB2-gene. Analysis of the independent cohort of 45 TN-ILCs from three different databases, confirmed similar percentage of pathogenetic and actionable mutations in ERBB2-gene(20%; 9/45). Among the top 10 molecular pathways significantly enriched for recurrently mutated genes in TN-ILCs(FDR, Highlights • Triple-negative ILCs are distinct from both TN-IDCs and endocrine-responsive ILC. • TN-ILCs are enriched for actionable mutations in ErbB2 gene and DNA Damage Response genes. • The Luminal Androgen Receptor (LAR) is the most prevalent subtype in TN-ILCs.

The role of alcohol intake in the risk of Hodgkin lymphoma (HL) is still largely unclear. To summarize the evidence on the issue, we carried out a meta-analysis of the available studies. We identified eight case-control and two cohort studies, including a total of 1488 cases of HL. We derived meta-analytic estimates using random-effects models, taking into account the correlation between estimates, and carried out a dose-risk analysis using nonlinear random-effects metaregression models. Compared with nondrinkers, the relative risk for alcohol consumers was 0.70 [95% confidence interval (CI), 0.60-0.81] overall, 0.66 (95% CI, 0.56-0.78) among case-control, and 0.92 (95% CI, 0.63-1.33) among cohort studies. Compared with nondrinkers, the pooled relative risks were 0.71 (95% CI, 0.57-0.89) for light (i.e. =1 drink/day) and 0.73 (95% CI, 0.60-0.87) for moderate-to-heavy (i.e. >1 drink/day) alcohol drinking. This meta-analysis suggests a favourable effect of alcohol on HL, in the absence, however, of a dose-risk relationship. The inverse association was restricted to - or greater in - case-control as compared with cohort studies. This indicates caution in the interpretation of results. © 2012 Wolters Kluwer Health | Lippincott Williams & Wilkins.

Objective: In order to provide an updated quantification of the association between alcohol drinking and epithelial ovarian cancer risk, we conducted a meta-analysis of published observational studies. Methods: Using PubMed, we performed a literature search of all case-control and cohort studies published as original articles in English up to September 2011. We included 27 observational studies, of which 23 were case-control studies, 3 cohort studies and one pooled analysis of prospective cohort studies, including a total of 16,554 epithelial ovarian cancer cases. We derived pooled meta-analytic estimates using random-effects models. Results: The pooled relative risk (RR) for any alcohol drinking compared with non/occasional drinking was 1.00 [95% confidence interval (CI), 0.95-1.05]. The RRs were 0.97 (95% CI, 0.92-1.02), 1.03 (95% CI, 0.96-1.11) and 1.09 (95% CI, 0.80-1.50) for light (= 1 drink/day), moderate (> 1 to < 3 drinks) and heavy drinking (= 3 drinks/day), respectively. In particular, the pooled RR for invasive epithelial ovarian cancers was 1.00 (95% CI, 0.95-1.06), while for borderline cancers was 0.96 (95% CI, 0.74-1.26). Stratified analyses across cancer histotypes revealed a modest protective effect of alcohol on endometrioid epithelial ovarian tumors (RR = 0.82, 95% CI, 0.70-0.96), while no association was found for serous (RR = 1.00, 95% CI, 0.84-1.19), mucinous (RR = 0.91, 95% CI, 0.78-1.08) and clear cell (RR = 0.93, 95% CI, 0.76-1.14) cancers. There was no evidence of publication bias. Conclusions: This comprehensive meta-analysis provided no evidence of a material association between alcohol drinking and epithelial ovarian cancer risk. © 2012 Elsevier Inc. All rights reserved.

Inconsistent results on the relationship between alcohol drinking and prostate cancer have been found. In order to provide a definite quantification of the dose-risk relation, we investigated the risk of prostate cancer at different levels of alcohol consumption, by conducting a meta-analysis of epidemiological studies. We performed a literature search using PubMed of all case-control and cohort studies published as original articles in English up to December 2010. We identified 50 case-control and 22 cohort studies, including a total of 52 899 prostate cancer cases. We derived pooled meta-analytic estimates using random-effects models, taking into account the correlation between estimates. We performed a dose-risk analysis using nonlinear random-effects meta-regression models. The overall relative risk for any alcohol drinking compared with non/occasional drinking was 1.06 [95% confidence interval (CI), 1.01-1.10]. The relative risks were 1.05 (95% CI, 1.02-1.08), 1.06 (95% CI, 1.01-1.11), and 1.08 (95% CI, 0.97-1.20) for light (=1 drink/day), moderate (>1 to

Epub 2011 May 5.; International audience; BACKGROUND: In order to provide a precise quantification of the association between alcohol drinking and esophageal and gastric cardia adenocarcinoma risk, we conducted a meta-analysis of available data. PATIENTS AND METHODS: We identified 20 case-control and 4 cohort studies, including a total of 5500 cases. We derived meta-analytic estimates using random-effects models, taking into account correlation between estimates, and we carried out a dose-risk analysis using nonlinear random-effects meta-regression models. RESULTS: The relative risk (RR) for drinkers versus nondrinkers was 0.96 [95% confidence interval (CI) 0.85-1.09] overall, 0.87 (95% CI 0.74-1.01) for esophageal adenocarcinoma and 0.89 (95% CI 0.76-1.03) for gastric cardia adenocarcinoma. Compared with nondrinkers, the pooled RRs were 0.86 for light (/= 4 drinks per day) alcohol drinking. The dose-risk model found a minimum at 25 g/day, and the curve was < 1 up to 70 g/day. CONCLUSIONS: This meta-analysis provides definite evidence of an absence of association between alcohol drinking and esophageal and gastric cardia adenocarcinoma risk, even at higher doses of consumption.

Epub 2011 May 2.; International audience; BACKGROUND: Whether an association between alcohol drinking and gastric cancer risk exists is an open question. In order to provide a definite quantification of the association between alcohol drinking and gastric cancer risk, we conducted a meta-analysis of available data. PATIENTS AND METHODS: We carried out a PubMed search of articles published up to June 2010 and identified 44 case-control and 15 cohort studies, including a total of 34 557 gastric cancer cases. We derived meta-analytic estimates using random-effects models, taking into account correlation between estimates. We carried out a dose-risk analysis using nonlinear random-effects meta-regression models. RESULTS: Compared with nondrinkers, the pooled relative risk (RR) was 1.07 [95% confidence interval (CI) 1.01-1.13] for alcohol drinkers and 1.20 (95% CI 1.01-1.44) for heavy alcohol drinkers (>/=4 drinks per day). The pooled estimates were apparently higher for gastric noncardia (RR for heavy drinkers=1.17, 95% CI 0.78-1.75) than for gastric cardia (RR=0.99, 95% CI 0.67-1.47) adenocarcinoma. The dose-risk model estimated a RR of 0.95 (95% CI 0.91-0.99) for 10 g/day and 1.14 (95% CI 1.08-1.21) for 50 g/day. CONCLUSIONS: This meta-analysis provides definite evidence of a lack of association between moderate alcohol drinking and gastric cancer risk. There was, however, a positive association with heavy alcohol drinking.

Neuroendocrine tumors (NETs) are more commonly slow-growing, therefore patients often receive chronic systemic therapies for tumor growth control and preservation of quality of life. Metronomic chemotherapy (mCT) is in line with this goal as it leads to stabilization of tumor growth over time without severe systemic toxicity. This is a retrospective analysis of patients with metastatic NETs receiving metronomic capecitabine (mCAP) or temozolomide (mTEM), at a NET-referral center. The aims of the study were to explore activity and safety of mCT and relationships between some characteristics of the patient population and clinical outcomes. Among a total of 67 patients with metastatic well or moderately differentiated (W/M-D) NETs, mostly gastroenteropancreatic (GEP) and nonfunctioning, 1.2 years (95% CI: 0.8–1.8) median progression-free survival (mPFS), and 3.0 years (95% CI: 2.3–4.9) median overall survival (mOS) were observed. Disease control rate was 85%. Grade 3 adverse events occurred in 15% of patients in mCAP and 13% in mTEM, and were mostly hematological and gastrointestinal. At univariate and multivariate analysis none of the variables analyzed (treatment regimen, sex, age at diagnosis, site of primary tumor and metastases, number of previous mCT lines, baseline tumor status before mCT, Ki67 value) were significantly correlated to OS and PFS. Our retrospective study suggested that mCAP and mTEM can be active and well tolerated in patients with metastatic W/M-D NETs, irrespective of the primary site, site of metastases, line of treatment and baseline tumor status.

Background: Alcohol intake is an established risk factor for colorectal cancer (CRC); however, there is limited knowledge on whether changing alcohol drinking habits during adulthood modifies CRC risk.Objective: Leveraging longitudinal exposure assessments on alcohol intake at different ages, we examined the relationship between change in alcohol intake and subsequent CRC risk.Methods: Within the European Prospective Investigation into Cancer and Nutrition, changes in alcohol intake comparing follow-up with baseline assessments were investigated in relation to CRC risk. The analysis included 191,180, participants and 1530 incident CRC cases, with exclusion of the first three years of follow-up to minimize reverse causation. Trajectory profiles of alcohol intake, assessed at ages 20, 30, 40, 50years, at baseline and during follow-up, were estimated using latent class mixed models and related to CRC risk, including 407,605 participants and 5,008 incident CRC cases.Results: Mean age at baseline was 50.2years and the follow-up assessment occurred on average 7.1 years later. Compared to stable intake, a 12 g/day increase in alcohol intake during follow-up was positively associated with CRC risk (HR = 1.15, 95%CI 1.04, 1.25), while a 12 g/day reduction was inversely associated with CRC risk (HR = 0.86, 95%CI 0.78, 0.95). Trajectory analysis showed that compared to low alcohol intake, men who increased their alcohol intake from early- to mid- and late-adulthood by up to 30 g/day on average had significantly increased CRC risk (HR = 1.24; 95%CI 1.08, 1.42), while no associations were observed in women. Results were consistent by anatomical subsite.Conclusions: Increasing alcohol intake during mid-to-late adulthood raised CRC risk, while reduction lowered risk

A fundamental challenge in meta-analyses of published epidemiological dose-response data is the estimate of the function describing how the risk of disease varies across different levels of a given exposure. Issues in trend estimate include within studies variability, between studies heterogeneity, and nonlinear trend components. We present a method, based on a two-step process, that addresses simultaneously these issues. First, two-term fractional polynomial models are fitted within each study included in the meta-analysis, taking into account the correlation between the reported estimates for different exposure levels. Second, the pooled dose-response relationship is estimated considering the between studies heterogeneity, using a bivariate random-effects model. This method is illustrated by a meta-analysis aimed to estimate the shape of the dose-response curve between alcohol consumption and esophageal squamous cell carcinoma (SCC). Overall, 14 case-control studies and one cohort study, including 3000 cases of esophageal SCC, were included. The meta-analysis provided evidence that ethanol intake was related to esophageal SCC risk in a nonlinear fashion. High levels of alcohol consumption resulted in a substantial risk of esophageal SCC as compared to nondrinkers. However, a statistically significant excess risk for moderate and intermediate doses of alcohol was also observed, with no evidence of a threshold effect. © 2010 John Wiley & Sons, Ltd.

Alcohol drinking is a known risk factor for laryngeal cancer. However, little information is available on the risk associated with light alcohol drinking. To address this issue, we conducted a meta-analysis using two methods: (i) random-effects models with reconstruction of alcohol consumption categories and calculation of risk estimates associated with predefined consumption levels using Hamling method and (ii) random-effects meta-regression models. The PubMed database was searched for all case-control or cohort studies published in the English language on the association between alcohol consumption and risk of laryngeal cancer. Forty studies (38 case-control, 2 cohort) reporting on at least three levels of consumption were included. Overall, alcohol drinking versus non-drinking was associated with an approximately 2-fold increase in risk of laryngeal cancer (RR = 1.90; 95% CI: 1.59-2.28). While light alcohol drinking (=1 drink/day) did not show any significant association with risk of laryngeal cancer (12 studies. RR = 0.88; 95% CI: 0.71-1.08), moderate drinking (>1 to

Oral and pharyngeal cancers are strongly related to alcohol drinking. We combined findings from all case-control and cohort studies published up to September 2009 and presented analyses by subsites, using a meta-analytic approach. Summary measures were obtained using random-effects models, and taking into account the correlation between estimates from the same study. We also performed a dose-risk analysis, using a random-effects meta-regression model. Compared to non- or occasional drinkers, the overall relative risks (RR) for light drinkers were 1.17 (95% confidence interval, CI, 1.01-1.35) for oral (nine studies) and 1.23 (95% CI, 0.87-1.73) for pharyngeal (five studies) cancer, with no significant heterogeneity between the two sites (p = 0.793). RRs for heavy drinkers were 4.64 (95% CI, 3.78-5.70) for oral (17 studies) and 6.62 (95% CI, 4.72-9.29) for pharyngeal (17 studies) cancer (p of heterogeneity between the two sites = 0.075). The summary RRs for heavy drinkers were 4.11 (95% CI, 2.46-6.87) for tongue (five studies), 7.76 (95% CI, 4.77-12.62) for oropharyngeal (four studies), and 9.03 (95% CI, 4.46-18.27) for hypopharyngeal (four studies) cancer. In conclusion, the alcohol-related RRs are higher for pharyngeal than for oral cancer, particularly at higher doses, while the association with cancer of the tongue was similar to that for oral cancer. © 2010 Elsevier Ltd.

Alcohol consumption, together with tobacco, is the best recognised risk factor for oral and pharyngeal cancers (OPC), but several important aspects of this association need to be further explored. In order to provide up to date and more precise quantification of the association between alcohol drinking and OPC risk, we conducted a meta-analysis of available data. We performed a PubMed search of articles published up to September 2009, and we identified 43 case-control and two cohort studies presenting results for at least three categories of alcohol drinking, including a total of 17,085 OPC cases. We derived meta-analytic summary estimates using random-effects models, and taking into account correlation between estimates. We also performed a dose-risk analysis using non-linear random-effects meta-regression models. The pooled relative risk (RR) was 1.21 (95% confidence interval, CI, 1.10-1.33) for1 drink per day, and rose to 5.24 (95% CI, 4.36-6.30) for heavy alcohol drinking (4 drinks per day). The dose-risk analysis resulted in RR of 1.29 for 10g ethanol/day, 3.24 for 50g ethanol/day, 8.61 for 100g ethanol/day, and 13.02 for 125g ethanol/day. This meta-analysis provides more precise evidence of a gross excess of OPC risk for heavy alcohol drinkers. It also indicates an increased risk for moderate doses, i.e., 1 drink or 10g ethanol/day. Alcohol consumption, together with tobacco, is the best recognised risk factor for oral and pharyngeal cancers (OPC), but several important aspects of this association need to be further explored. In order to provide up to date and more precise quantification of the association between alcohol drinking and OPC risk, we conducted a meta-analysis of available data. We performed a PubMed search of articles published up to September 2009, and we identified 43 case-control and two cohort studies presenting results for at least three categories of alcohol drinking, including a total of 17,085 OPC cases. We derived meta-analytic summary estimates using random-effects models, and taking into account correlation between estimates. We also performed a dose-risk analysis using non-linear random-effects meta-regression models. The pooled relative risk (RR) was 1.21 (95% confidence interval, CI, 1.10-1.33) for ≤1 drink per day, and rose to 5.24 (95% CI, 4.36-6.30) for heavy alcohol drinking (≥4 drinks per day). The dose-risk analysis resulted in RR of 1.29 for 10 g ethanol/day, 3.24 for 50 g ethanol/day, 8.61 for 100 g ethanol/day, and 13.02 for 125 g ethanol/day. This meta-analysis provides more precise evidence of a gross excess of OPC risk for heavy alcohol drinkers. It also indicates an increased risk for moderate doses, i.e., ≤1 drink or 10 g ethanol/day. © 2010 Elsevier Ltd. All rights reserved.

In the last few years, ultrasound-guided vacuum-assisted breast biopsy (US-VABB) has replaced surgical biopsy due to higher diagnostic accuracy and lower patient discomfort, and, at present, an even greater possibility is represented by the new wireless ultrasound-guided VAB device (Wi-UVAB). The purpose of our study is to determine the diagnostic accuracy of this new device in a sizeable representative number of patients. From January 2014 to June 2018, 168 biopsies were performed in our institution using the new Wi-UVAB device. We analyzed sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of biopsies obtained with the new device using surgical results as reference point, following patients for at least one year. In our cohort, we obtained a complete sensitivity of 97.5%, an absolute sensitivity of 94.3%, a complete specificity of 98%, and an absolute specificity of 98%. The positive predictive value of the procedure was 97.5% while the negative predictive value was 98%. The diagnostic accuracy was 98%. The Wi-UVAB is a safe procedure with high diagnostic accuracy, comparable to that of the traditional vacuum-assisted breast biopsy and even higher than that of core needle biopsy (CNB). Moreover, the Wi-UVAB is easy to use and shows low costs as core needle biopsy (CNB).

Purpose: The careful evaluation of MDCT is an essential step for the treatment planning in pre-treatment imaging work-up for Trans-Arterial Radio Embolization (TARE). It may provide unique volumetric data (CTVs), which are information useful for an effective and safe TARE. The purpose of this study is to demonstrate that the radiographer is able to calculate CTVs of TARE simulation with the same precision as the interventional radiologist. Methods: This study retrospectively considers 17 consecutive patients (8 males, 9 females; mean age 66.3 ± 13.2 years) who underwent pre-treatment work-up for TARE, between May 2019 and February 2020 (trial ID:2234 - protocol). For each patient, four specific parameters are evaluated from MDCT achieved during treatment simulation: healthy liver volume (HLV), the whole hepatic parenchyma (THV = healthy liver and TTV = tumour) involved by TARE, and whole liver volume (WLV). Four independent observers—R1 (expert interventional radiologist), T1, T2, and T3 (radiographers, with different experiences in the field of interventional radiology)—are involved in the imaging analysed. Results: All the 4 observers detected the same number of hepatic lesion(s) per patient. Regarding the three radiographers, the intra-observer reliability for CTVs is very high 0.997 to 1.000 (95%CI). Also inter-observer reproducibility between radiographers is excellent regarding CTVs, 0.965 to 0.999 (95%CI). The accuracy of radiographer evaluation is very high 0.964 to 0.999 (95%CI). Conclusions and implications for practice: The high intra- and inter-observer reproducibility shows that a properly trained radiographers might have the same accuracy as interventional radiologists, in assessing liver CTV data for planning TARE.

Aims: To report toxicity of a hypofractionated scheme of whole-breast (WB) intensity-modulated radiotherapy (IMRT) with simultaneous integrated boost (SIB) to the tumor bed (TB) using Tomotherapy® with Direct modality. Methods: Patients with early breast cancer, undergoing radiotherapy (RT) in 15 daily fractions to WB (prescription dose 40.05 Gy) and SIB to the TB (48 Gy), between 2013 and 2017, was analyzed. Primary endpoint was acute and intermediate toxicity assessed at the end and within 6 months from RT, according to Radiation Therapy Oncology Group (RTOG) scale. Secondary endpoints included early chronic toxicity at 12-months follow-up, using the Late Effects Normal Tissue Task Subjective, Objective, Management, and Analytic (LENT-SOMA) scale, and cosmesis using Harvard criteria. Results: The study population was of 287 patients. Acute and intermediate toxicity was collected among 183 patients with data available at the end of RT and within 6 months, 85 (46%) experienced G2 toxicity and 84 (46%) G1 toxicity, while 14 (8%) did not report toxicity at any time. A significant reduction of any grade toxicity was observed between the two time points, with the majority of patients reporting no clinically relevant toxicity at 6 months. At univariate analysis, age < 40 years, breast volume > 1000 cm3 and Dmax ≤ 115% of prescription dose were predictive factors of clinically relevant acute toxicity (G ≥ 2) at any time. At multivariable analysis, only age and breast volume were confirmed as predictive factors, with Relative Risks (95% Confidence Intervals): 2.02 (1.13–3.63) and 1.84 (1.26–2.67), respectively. At 12-month follow-up, 113 patients had complete information on any toxicity with 53% of toxicity G < 2, while cosmetic evaluation, available for 102 patients, reported a good–excellent result for 86% of patients. Conclusions: Hypofractionated WB IMRT with a SIB to the TB, delivered with TomoDirect modality, is safe and well-tolerated. Most patients reported no toxicity after 6 months and good–excellent cosmesis. Predictive factors of clinically relevant toxicity might be considered during treatment planning in order to further reduce side effects.

The purpose of this study is the evaluation of clinical and surgical impact of the Z0011 trial criteria on the management of breast cancer (BC) patients undergoing breast conservative surgery (BCS) at the European Institute of Oncology (IEO). We studied 1386 patients who underwent BCS and sentinel lymph node biopsy (SLNB) from July 2016 to July 2018. Clinical evaluation, breast ultrasound, mammogram, and cyto/histological examination were performed for all patients at the time of diagnosis. Frozen sections of the sentinel lymph node (SLN) were not performed for any patient. Patients who underwent neo-adjuvant therapy were excluded. To evaluate the results before and after the introduction of Z0011 criteria, a group of 1425 patients with the same characteristics who underwent BCS and SLNB from July 2013 to July 2015 were analyzed. We studied the characteristics of the patients by nodal status, and we observed that T stage, tumor grade, and lymphovascular invasion were statistically related with the highest rate of positive SLN. Of the 1386 patients who underwent surgery after the introduction of the Z011 trial, 1156 patients (83.4%) had negative SLN, 230 patients (16.6%) had positive SLN. Subsequent axillary lymph node dissection (ALND) was performed in only 7 cases (3.0%). Of the 1425 patients operated before the introduction of the Z0011 trial, 216 patients had subsequent ALND (15%). The reduction in the number of ALND performed after the introduction of Z0011 is statistically significant, and this could result in a remarkable reduction of the comorbidities of our patients.

Objectives: To develop a novel nomogram to identify candidates for active surveillance (AS) that combines clinical, biopsy and multiparametric magnetic resonance imaging (mpMRI) findings; and to compare its predictive accuracy to, respectively: (i) Prostate Cancer Research International: Active Surveillance (PRIAS) criteria, (ii) Johns Hopkins (JH) criteria, (iii) European Association of Urology (EAU) low-risk classification, and (iv) EAU low-risk or low-volume with International Society of Urological Pathology (ISUP) Grade Group (GG) 2 classification. Patients and Methods: We selected 1837 patients with ISUP GG1 or GG2 prostate cancer (PCa), treated with radical prostatectomy (RP) between 2012 and 2018. The outcome of interest was the presence of unfavourable disease (i.e., clinically significant PCa [csPCa]) at RP, defined as: ISUP GG (Formula presented.) 3 and/or pathological T stage (pT) ≥3a and/or pathological N stage (pN) 1. First, logistic regression models including PRIAS, JH, EAU low-risk, and EAU low-risk or low-volume ISUP GG2 binary classifications (not eligible vs eligible) were used. Second, a multivariable logistic regression model including age, prostate-specific antigen density (PSA-D), ISUP GG, and the percentage of positive cores (Model 1) was fitted. Third, Prostate Imaging-Reporting and Data System (PI-RADS) score (Model 2), extracapsular extension (ECE) score (Model 3) and PI-RADS + ECE score (Model 4) were added to Model 1. Only variables associated with higher csPCa rates in Model 4 were retained in the final simplified Model 5. The area under the receiver operating characteristic curve (AUC), calibration plots and decision curve analyses were used. Results: Of the 1837 patients, 775 (42.2%) had csPCa at RP. Overall, 837 (47.5%), 986 (53.7%), 348 (18.9%), and 209 (11.4%) patients were eligible for AS according to, respectively, the EAU low-risk, EAU low-risk or low-volume ISUP GG2, PRIAS, and JH criteria. The proportion of csPCa amongst the EAU low-risk, EAU low-risk or low-volume ISUP GG2, PRIAS and JH candidates was, respectively 28.5%, 29.3%, 25.6% and 17.2%. Model 4 and Model 5 (in which only PSA-D, ISUP GG, PI-RADS and ECE score were retained) had a greater AUC (0.84), compared to the four proposed AS criteria (all P&nbsp

Objectives Bleomycin, etoposide, and cisplatin (BEP) is the most common and successful chemotherapy regimen for germ-cell tumor (GCT) patients, accompanied by a bleomycin-induced dose-dependent lung toxicity in certain patients. In an attempt to reduce bleomycin-toxicity, we developed a modified-BEP (mBEP) regimen. Materials and methods Between August 2008 and February 2018, 182 unselected mainly testicular GCT patients (39 with adjuvant purpose and 143 with curative purpose) received a tri-weekly 5-day hospitalization schedule with bleomycin 15 U intravenous (IV) push on day 1 and 10 U IV continuous infusion over 12 hours on days 1 to 3, cisplatin 20 mg/m IV, and etoposide 100 mg/m IV on days 1 to 5. Pulmonary toxicity was assessed through chest computed tomography scan and clinical monitoring. Results Median number of mBEP cycles was 3 (range: 1 to 4). In the curative setting, according to the International Germ Cell Cancer Collaborative Group (IGCCCG) prognostic system, 112, 21, and 9 patients had good-risk, intermediate-risk, and poor-risk class, respectively; 66 (46%) patients had complete response (CR), 67 (47%) had partial response (52 of whom became CR afterwards), 6 (4%) had stable disease (that in 3 became CR afterwards), 3 (2%) progressed, and 1 (1%) died of brain stroke. At a median follow-up of 2.67 years (interquartile range: 1.23-5.00 y), 1 and 5-year overall survival and progression-free survival were 99% and 95%, and 90% and 88%, respectively. In the entire patient population, there was grade 3/4 neutropenia in 92 patients (51%), febrile neutropenia in 11 patients (6%), grade 1/2 nausea in 74 patients (41%), and no death due to pulmonary toxicity. Conclusion In GCT patients, our mBEP-schedule would suggest an effective treatment modality without suffering meaningful pulmonary toxicity.

Objectives Tumor-associated antigens (TAAs) are frequently overexpressed in several cancer types. The aim of this study was to investigate the expression of TAAs in breast cancer. Material and methods A total of 250 selected invasive breast cancers including 50 estrogen receptor (ER)-positive (Luminal B like), 50 triple-negative (TN), 50 ER-positive lobular type, 50 ER- and progesterone receptor (PgR)-positive (Luminal A like) and 50 cerbB2-positive breast cancers, were assessed for New York esophageal squamous cell carcinoma-1 (NY-ESO-1), Wilms tumor antigen (WT-1) and PReferentially expressed Antigen of MElanoma (PRAME) antigen expression by immunohistochemistry (IHC). Results A significantly higher expression of cancer testis (CT)-antigens NY-ESO-1 and WT-1 antigen was detected in TN breast cancers compared with ER-positive tumors. NY-ESO-1 overexpression (score 2 + and 3+) assessed by monoclonal and polyclonal antibodies was detected in 9 (18%) TN cancers as compared to 2 (4%) ER-positive tumors (p = 0.002). WT1 over-expression (score 2 + and 3+) was confirmed in 27 (54%) TN tumor samples as compared to 6 (12%) ER-positive (p, Highlights • Tumor-associated antigens are frequently overexpressed in several cancer types, being also associated with poorer patients’ survival outcomes. • Our study confirmed that NY-ESO-1 and WT1 antigens are higher expressed in triple-negative than in other breast cancer subtypes. • Given the limited therapeutic options for triple-negative breast cancer patients, the assessment of WT1 and NY-ESO-1 antigens expression in breast cancer tissue at surgery may allow to identify patients potentially candidate to adjuvant peptide vaccines, alone or in combination with other systemic therapies.

Background: Limited evidence is available on effectiveness of clinicoradiological follow-up of early-stage NSCLC patients. MAGRIT was a phase III adjuvant RCT conducted in surgically resected stage IB-IIIA NSCLC patients, in which all participants had a prospectively defined intensive clinicoradiological follow-up. Methods: At patient-level data, we analyzed detection modality of disease recurrences and new primary lung cancer (i.e. detected by clinicoradiological scheduled exams versus by interim unscheduled exams), features associated with higher risk of locoregional and/or distant recurrence, and recurrence rates over time. Results: In the 2261 patients studied, there was a significant association between the type of recurrence and the modality of detection: 88.4% (95% CI, 84%–91%) of the locoregional recurrences and 93.2% (95% CI, 84%–99%) of the new primary lung cancers were detected by scheduled exams, whereas this was only 68.7% (95% CI, 65%–73%) for distant metastases (p < 0.001). Survival of patients with locoregional recurrence or new primary lung cancer detected by scheduled exams was significantly better as compared with those detected by unscheduled exams (HR 0.56, 95% CI 0.36–0.87; p = 0.01). Survival was similarly poor in patients with distant recurrences, both with scheduled and unscheduled detection (3-year survival after recurrence 22.0% and 21.8%, respectively). Recurrence rate was the highest in the first 18 months after surgery—with a peak between month 6 and 12—decreasing thereafter. The hazard of a second primary lung cancer was constant over time. Conclusion: Intensive follow-up is effective in detecting locoregional recurrences and second primary lung cancers, with impact on patients’ survival but did not influence the detection of distant recurrences.

Background: To assess the clinical usefulness of serum tumor markers for early detection of distant breast cancer recurrence using FDG-PET/CT. Methods: We retrospectively analyzed 561 consecutive patients who underwent surgery for invasive primary breast cancer and had increased tumor markers (CA 15-3 and CEA) after completion of locoregional therapy. FDG-PET/CT data were reviewed for all cases. CA 15-3 and CEA were evaluated both in a continuous and in a quartile (Q) distribution. The Wilcoxon rank-sum test and logistic regression models were used to evaluate the association between increased tumor marker values and the presence (and type) of distant metastases. Results: The median value of CA 15-3 was 35.0 U/mL (IQR, 29.5–43.0) in cases where no distant metastases were detected, and it was 58.9 U/mL (IQR, 40.0–108.0) in cases where metastases were detected (p < 0.001). The median value of CEA was 6.6 U/mL (IQR, 4.4–10.0) in cases of no metastases and 12.4 U/mL (IQR, 6.9–30.0) in cases of metastases (p < 0.001). Increased levels of both tumor markers (Q3 and Q4) were strongly associated with the presence of distant metastases. The association between CA 15-3 and bone/liver metastases was stronger compared with other types of metastases (p heterogeneity between odds ratios [ORs] = 0.03 for Q3 and Conclusion: Increased tumor marker levels detected in asymptomatic breast cancer patients during adjuvant therapies and follow-up are significantly predictive of distant metastases identified on FDG-PET/CT.

Obesity correlates with hematologic malignancies including leukemias, but risk of specific leukemia subtypes like acute promyelocytic leukemia and underlying molecular mechanisms are poorly understood. We explored multiple datasets for correlation between leukemia, body mass index (BMI) and molecular features. In a population-based study (n=5.2 million), we correlated BMI with promyelocytic leukemia, and other acute myeloid, lymphoid or other leukemias. In cross-sectional studies, we tested BMI deviation in promyelocytic leukemia trial cohorts from that expected based on national surveys. We explored The Cancer Genome Atlas for transcriptional signatures and mutations enriched in promyelocytic leukemia and/or obesity, and confirmed a correlation between body mass and FLT3 mutations in promyelocytic leukemia cohorts by logistic regression. In the population-based study, hazard ratio per 5 kg/m2 increase was: promyelocytic leukemia 1.44 (95%CI: 1.0-2.08), non-promyelocytic acute myeloid leukemias 1.17 (95%CI: 1.10-1.26), lymphoid leukemias 1.04 (95%CI: 1.0-1.09), other 1.10 (95%CI: 1.04-1.15). In cross-sectional studies, body mass deviated significantly from that expected (Italy: P

Background The latest National Comprehensive Cancer Network Breast Cancer Guidelines still discourage repeat sentinel node biopsy (SNB) after mastectomy, and the largest multicentric study available reports only 35 cases in the absence of previous axillary dissection (AD). Methods From January 2003 to November 2018, 89 patients of the European Institute of Oncology with local recurrence of breast cancer after mastectomy, free of distant metastases, with a clinically negative axilla and a negative axillary ultrasound, in absence of AD, underwent lymphatic mapping before wide local excision. Results During surgery, SNB was successful for 99% of the patients, with 14% being metastatic. Additional metastatic nodes removed by AD after a positive sentinel node occurred in 82% of cases. After a medium follow-up period of 3.7 years, the overall survival rate was 96.7%, and the disease-free survival rate was 84.4%. No axillary relapse after AD was recorded. One patient who refused human epidermal growth factor receptor 2 (HER2)-targeted treatment experienced ipsilateral axillary recurrence after a negative repeat SNB. The first axillary level was never directly irradiated because all the patients with positive repeat SNB underwent AD. For invasive luminal-like HER2-negative recurrences, the metastatic sentinel node was significantly associated with the choice to prescribe adjuvant chemotherapy (p = 0.003). Conclusions In specialized centers, repeat axillary SNB for patients with local recurrence after mastectomy in the absence of previous AD can represent a safe option for detection and removal of occult axillary disease that would otherwise not be excised/irradiated to achieve better local control and could possibly influence the choice of adjuvant treatments.
