This study aims at providing an accurate and up-to-date quantification of the dose–response association between cigarette smoking and gastric cancer (GC) risk, overall and by subsite. We conducted a systematic review and meta-analysis of case–control and cohort studies on the association between cigarette smoking and GC risk published up to January 2023. We estimated pooled relative risks (RR) of GC and its subsites according to smoking status, intensity, duration, and time since quitting. Among 271 eligible articles, 205 original studies were included in this meta-analysis. Compared with never smokers, the pooled RR for GC was 1.53 (95% confidence interval; CI 1.44–1.62; n = 92) for current and 1.30 (95% CI 1.23–1.37; n = 82) for former smokers. The RR for current compared with never smokers was 2.08 (95% CI 1.66–2.61; n = 21) for gastric cardia and 1.48 (95% CI 1.33–1.66; n = 8) for distal stomach cancer. GC risk nonlinearly increased with smoking intensity up to 20 cigarettes/day (RR:1.69; 95% CI 1.55–1.84) and levelled thereafter. GC risk significantly increased linearly with increasing smoking duration (RR: 1.31; 95% CI 1.25–1.37 for 20 years) and significantly decreased linearly with increasing time since quitting (RR: 0.65; 95% CI 0.44–0.95 for 30 years since cessation). The present meta-analysis confirms that cigarette smoking is an independent risk factor for GC, particularly for gastric cardia. GC risk increases with a low number of cigarettes up to 20 cigarettes/day and increases in a dose-dependent manner with smoking duration.

Background: Malignant pheochromocytomas (PCCs) and paragangliomas (PGLs) are rare tumors and available systemic therapies are limited. Aim: To explore the role of peptide receptor radionuclide therapy (PRRT) with Yttrium-90 (90Y) and Lutetium-177 (177Lu) peptides in pheochromocytomas (PCCs) and paragangliomas (PGLs). Methods: We retrospectively analyzed more than 1500 patients with histologically proven neuroendocrine tumors treated with 177Lu- or 90Y-DOTA-TATE or –TOC between 1999 to 2017 at our Institute. Overall, 30 patients with confirmed malignant PCCs and PGLs matched inclusion/exclusion criteria and were considered eligible for this analysis. Results: Thirty (n = 30) patients were treated: 22 with PGLs and 8 with PCCs (12 M and 18 F, median age 47 [IQR: 35–60 years]). Eighteen patients (n = 18) had head and neck PGLs, 3 patients thoracic PGLs and 1 patient abdominal PGL. Sixteen patients (53%) had locally advanced and fourteen (47%) had metastatic disease. Twenty-seven (90%) patients had disease progression at baseline. Four (13%) patients were treated with 90Y, sixteen (53%) with 177Lu and ten (33%) with 90Y + 177Lu respectively. The median total cumulative activity from treatment with 90Y- alone was 9.45 GBq (range 5.11–14.02 GBq), from 177Lu- alone was 21.9 GBq (7.55–32.12 GBq) and from the combination treatment was 4.94 GBq from 90Y- and 6.83 GBq from 177Lu- (ranges 1.04–10.1 and 2.66–20.13 GBq, respectively). Seven out of 30 (23%) patients had partial response and 19 (63%) stable disease. Median follow up was 8.9 years (IQR: 2.9–12). The 5-y and 10-y PFS was 68% (95% CI: 48–82) and 53% (95% CI: 33–69), respectively, whereas 5-y and 10-y OS was 75% (95% CI: 54–87) and 59% (95% CI: 38–75), respectively. Grade 3 or 4 acute hematological toxicity occurred in three patients, two with leucopenia and one with thrombocytopenia, respectively. Conclusion: PRRT with 177Lu- or 90Y-DOTA-TATE or –TOC is feasible and well tolerated in advanced PGLs and PCCs.

Purpose: To compare the diagnostic performance (detection, assessment of correct disease extent and multifocality/centricity) of Contrast-Enhanced Mammography (CEM) Versus Breast Magnetic Resonance (MRI) in the study of lobular neoplasms. Methods: We retrospectively selected all the patients who underwent surgery for a lobular breast neoplasm, either an in situ or an invasive tumor, and had undergone both breast CEM and MRI examinations during the pre-surgical planning. Wilcoxon Signed Rank test was performed to assess the differences between size measurements using the different methods and the post-surgical pathological measurements, considered the gold standard. The agreement in identifying multifocality/multicentricity among the different methods and the pathology was assessed using the Kappa statistics. Results: We selected 19 patients, of which one presented a bilateral neoplasm. Then, the images of these 19 patients were analyzed, for a total of 52 malignant breast lesions. We found no significant differences between the post-surgical pathological size of the lesions and the calculated size with CEM and MRI (p-value of the difference respectively 0.71 and 0.47). In all 20 cases, neoplasm detection was possible both with CEM and MRI. CEM and MRI showed an excellent ability to identify multifocal and multicentric cases (K statistic equal to 0.93 for both the procedures), while K statistic was 0.11 and 0.59 for FFDM and US, respectively. Conclusion: The findings of this study suggest that CEM is a reliable imaging technique in the preoperative setting of patients with lobular neoplasm, with comparable results to breast MRI.

Introduction: To offer an extensive retrospective experience on the management of male breast cancer. Methods: A multicenter retrospective observational cohort study was conducted, including male patients diagnosed with breast cancer (invasive or in situ) in 12 Italian breast units from January 1975 to December 2019. Patients aged 18 years or older were assessed for eligibility. Exclusion criteria were metastatic cancer at diagnosis, previous cancer(s), received neoadjuvant treatment, incomplete data on (neo) adjuvant treatment(s), and/or follow-up data. Data on radiological examinations, demographic characteristics, risk factors, histological features, receptor status, treatments, and follow-up were collected. Results: In a series of 671 male patients with breast cancer assessed for eligibility, 403 (28 in situ and 375 invasive neoplasms) were included in the study. All included patients underwent surgery. The median age at surgery was 63.8 years (IQR 56.1–72.1). In 68% of cases, patients underwent echography, and in 55.1%, a mammography. Most patients were ER and PR positive (63.8%), HER2 negative (80.4%), with high (≥ 20%) Ki67 values (61.3%), and luminal B subtype (51.1%). The 10-year overall survival was 73.6% (95% CI 67.0–79.1) for invasive breast cancer and 90% (95% CI 65.6–97.4) for in situ breast cancer. In patients with invasive breast cancer, at univariable analysis, having a G3 tumor (vs. G1), pT2/3/4 (vs. pT1), pN2/3 (vs. pN0), luminal B subtype with Ki67 ≥ 20% (vs. Luminal A), were significantly associated with a higher risk of death. In multivariable analyses, pT2/3/4 (vs. pT1) remained significantly associated with a higher risk of death (HR 3.14, 95% CI 1.83–5.39), and having a HER2 positive or a triple-negative subtype (vs. Luminal A) was also significantly associated with a higher risk of mortality (HR 4.76, 95% CI 1.26–18.1). Conclusion: Male breast cancer is a rare disease, the better understanding of which is necessary for a more effective diag

Purpose: Data on the prognostic impact of the micropapillary component in breast cancer are limited. The purpose of this study was to investigate the clinicopathological characteristics and long-term outcomes of pure and mixed invasive micropapillary breast cancer (IMPC) patients compared to invasive ductal cancer (IDC) patients. Methods: This retrospective study analysed all IMPC and IDC patients treated at the European Institute of Oncology (IEO) between 1997 and 2019. The overall cohort of IMPC patients was divided in two groups, pure and mixed IMPC. Each patient with mixed or pure IMPC was matched with one patient with IDC, based on year of surgery, age, pT, pN, and molecular subtype. Results: A total of 30,115 IDC, 120 pure IMPC and 150 mixed IMPC patients were considered eligible. Compared to IDC, pure and mixed IMPC patients presented a higher rate of locally advanced disease (pT2-T3, pN2-N3), vascular invasion, and Luminal B subtype. After matching, pure and mixed IMPC showed a significant higher rate of vascular invasion compared to IDC patients (p < 0.001). Invasive disease-free survival was better in IDC compared to pure IMPC patients (p = 0.11). Long-term overall survival was significantly worse in pure IMPC group compared to IDC group (p = 0.004), being instead similar between mixed IMPC vs matched IDC (p = 0.07). Conclusion: These real-world data reported the worse prognosis of pure IMPC compared to IDC, highlighting the peculiar prognostic value of the micropapillary subtype itself in the decision-making process of IMPC management. An accurate pre-surgical diagnostic evaluation and a multidisciplinary approach are pivotal to best personalize its treatment.

Purpose: Despite extensive research on cancer and work-related outcomes, evidence from longitudinal cohort studies is limited, especially in young women with breast cancer (BC). We aimed to investigate employment trajectories in young BC survivors and to identify potential factors associated with changes in work activity. Methods: The HOHO European prospective multicenter cohort study enrolled 300 young women (≤ 40 years) with newly diagnosed BC. Women completed surveys at baseline and every 6 months for 3 years, then yearly for up to 10 years to assess, among other variables, employment status, sociodemographic, medical, and treatment data. Symptoms were assessed by the Breast Cancer Prevention Trial symptom scales and single items from the Cancer Rehabilitation Evaluation System. Univariable and multivariable multinomial logistic regression analyses identified factors associated with changes in employment status. Results: Among the 245 women included in this analysis, 85% were employed at the last individual post-baseline assessment (1 to 10 years). At 5 years, women had a 29.4% probability (95% CI: 23.6–35.5) of experiencing any reduction and a 14.9% probability (95% CI: 10.6–19.9) of experiencing any increase in work activities. Being enrolled in Switzerland (vs. Italy) and reporting more trouble in performing daily activities were significantly associated with work reduction. Conclusion: Our results suggest that most young BC survivors remain employed in the long-term. Implications for Cancer Survivors: Regular evaluation of symptoms which may interfere with daily life and identification of financial discomfort is critical in providing timely and individually tailored interventions and in limiting unwanted reductions in work activities.

Purpose: To evaluate oncological outcomes and late toxicities in a retrospective series of patients with locally-extended anal squamous cell carcinoma (ASCC), treated with curative Intensity Modulated Radiotherapy (IMRT) and chemotherapy. Methods: ASCC patients who underwent chemo-radiotherapy with IMRT from 2010 to 2020 were included. Oncological outcomes were assessed in terms of overall survival (OS), disease-free survival (DFS), colostomy-free survival (CFS) and event-free survival (EFS). Late toxicity was detected according to CTCAE v.5.0 and RTOG late radiation morbidity scoring system. Results: Ninety-five patients were included. Most patients (83%) received chemotherapy with oral Fluoropyrimidine plus Cisplatin. The median follow-up was 5.5 years. The OS was 85.2%, 82.1% and 79.3% at 3, 5 and 8 years, respectively. The DFS was 73.1%, 70%, and 65.3% at 3, 5 and 8 years, respectively; 3, 5 and 8 years CFS was 86.2%, 84.3% and 84.3%, respectively. The EFS was 71%, 67.9% and 63.1%, at 3, 5 and 8 years, respectively. On univariable analysis, a statistically significant lower OS was found for patients with T3-T4 stage (HR = 4.58, p = 0.005) and overall treatment time (OTT) ≥ 47 days (HR = 3.37, p = 0.038). A statistically significant lower DFS was reported for patients with T3-T4 stage (HR = 2.72, p = 0.008) and Serum Squamous Cell Carcinoma Antigen (SCC) value post-RT > 1.5 (HR = 2.90, p = 0.038.). Ten severe late toxicity (≥ G3) events were reported in 8 patients (8.6%). Conclusions: Our data confirm IMRT concomitant with a Cisplatin-based chemotherapy as an effective treatment of ASCC, ensuring acceptable long-term toxicities and good oncological outcomes.

Purpose: The development of the adjuvant therapy requires that clinicians and patients should discuss the magnitude of benefit of treatment for individual patient, estimating the pros and cons and the personal preferences. The aim of the present study was to determine the preferences of women treated with adjuvant hormonal therapy (HT) for breast cancer. Methods: The analyses were conducted into three different groups of early breast cancer patients to evaluate the survival benefit needed to make treatment worthwhile before starting HT (A), after a few months from the beginning (B) and after several years of HT (C). The questionnaires, showing hypothetical scenarios based on potential survival times and rates without HT, were used to determine the lowest gains women judged necessary to make the treatment worthwhile. Results: A total of 452 patients were included in the study: 149 in group A, 150 in group B and 153 in group C. In group C, 65% of patients were receiving HT with aromatase inhibitors (with or without a LHRH analogue). In the groups A, B, C 8%, 20% and 26%, respectively, received adjuvant chemotherapy. Overall, 355 women (79%) had children. The responses were quite similar between the three groups. A median gain of 10 years was judged necessary to make adjuvant HT worthwhile based on the hypothetical scenario of untreated mean survival time of 5 and 15 years. Median gain of 20% more women surviving was judged necessary to make adjuvant HT worthwhile based on an untreated 5-year survival rate expectation of 60%. Cognitive dysfunction was considered the side effect least compatible with the continuation of treatment in all three groups. Conclusions: This is a large study of patient preferences on HT. Compared with other studies with similar design, the patients included in the present study required larger benefits to make adjuvant therapy worthwhile.

Background: The aim of this work is to evaluate pattern of care and clinical outcome in a large series of patients with in-breast recurrence (IBR), after quadrantectomy and intraoperative radiation therapy with electrons (IOERT) as partial breast irradiation. Patients and Methods: Patients with IBR after IOERT, treated with salvage surgery ± adjuvant reirradiation (re-RT), were selected from a multiinstitution database. Disease-free survival (DFS), overall survival (OS), cumulative incidence of second IBR, and distant metastases (DM) were estimated. Results: A total of 224/267 patients from seven institutions were included. Primary tumors received 21 Gy. Median time to first IBR was 4.3 years (range 2.6–6.1 years). Salvage mastectomy and repeat quadrantectomy were performed in 135 (60.3%) and 89 (39.7%) patients, followed by adjuvant re-RT in 21/135 (15.5%) and 63/89 (70.8%), respectively. Median follow-up after salvage treatment was 4.1 years. Overall, 5- and 8-year outcomes were as follows: cumulative incidence of second IBR: 8.4% and 14.8%; cumulative incidence of DM: 17.1% and 22.5%; DFS: 67.4% and 52.5%; OS: 89.3% and 74.7%. The risk of second IBR was similar in the salvage mastectomy and repeat quadrantectomy + RT groups [hazard ratio (HR) 1.41, p = 0.566], while salvage mastectomy patients had greater risk of DM (HR 3.15, p = 0.019), as well as poorer DFS (HR 2.13, p = 0.016) and a trend towards worse OS (HR 3.27, p = 0.059). Patients who underwent repeat quadrantectomy alone had worse outcomes (second IBR, HR 5.63, p = 0.006; DFS, HR 3.21, p = 0.003; OS, HR 4.38, p = 0.044) than those adding re-RT. Conclusions: Repeat quadrantectomy + RT represents an effective salvage approach and achieved local control comparable to that of salvage mastectomy.

Purpose: The purpose of this study was to investigate survival outcomes and safety after chemoembolization using irinotecan-loaded small-size beads (DEB-IRI) in patients with colorectal liver metastases unresponsive to standard chemotherapy. Materials and methods: Between December 2013 and August 2019, fifty-five patients (32 males, median age 64.5 years) with pretreated colorectal liver metastases unresponsive to standard chemotherapy underwent 197 chemoembolization procedures (mean 3.6 ± 2.3 SD per patient). Thirty patients (30/55; 55%) had extrahepatic disease metastatic to the lungs, lymph nodes or peritoneum. Local tumor control was evaluated at 3, 6, 9 and 12 months. Median overall survival, survival rates at 1 and 2 year and adverse events were evaluated. Results: Local tumor control was achieved in 32/55 (58%), 12/55 (22%), 4/55 (7%) and 2/55 (4%) patients at 3, 6, 9 and 12 months, respectively. Median overall survival was 9.9 months (95% CI: 6.2–14.2 months) with 1- and 2-year survival rates of 45% and 15%, respectively. A total of 30 (15%) G1-G3 treatment-related adverse events occurred across all embolization procedures. No severe treatment-related adverse events occurred. Conclusion: Chemoembolization using irinotecan-loaded small-size beads is a safe and effective procedure as a salvage treatment in patients with colorectal liver metastases, showing good results in terms of liver-specific progression free survival and overall survival.

Purpose: To present an overview of the management of male patients with Ductal Carcinoma In Situ of the breast (male DCIS). Methods: We retrospectively studied all male patients with a diagnosis of pure DCIS from January 1999 to December 2018: 20 patients were identified in our cancer referral center. We collected data regarding clinical presentation, age of onset, radiological features, receptor status of the neoplasm, histological type, and the follow-up of those patients. Results: The median age was 62 years (range 21–80). All patients underwent surgery, in 15/20 (75%) cases a mastectomy was carried out. Two patients (10%) underwent endocrine treatment and 1/20 (5%) underwent radiotherapy. The receptor status for 15/20 patients was documented: 13/15 patients were ER+/Pr+. In 3 cases the Ki 67% was positive (i.e., > 20%). All cases were negative for Her2. The median follow-up time was 9.0 years (IQR 4.0–13.7). Only one patient had an ipsilateral recurrence with the finding of an infiltrating carcinoma in the same breast after 14 years. The 5-year disease-free survival was 92.9%. Conclusion: Pure DCIS in men is an extremely rare disease: proper diagnosis and management allow an excellent prognosis.

Purpose: Metastatic triple negative breast cancer (mTNBC) is associated with poor prognosis and limited treatment options. It is known to be high immunogenic, with a high level of programmed cell death-ligand 1 (PD-L1) expression. PD-L1 expression in TNBC does not have a clear prognostic relevance. In this study, we aimed to assess survival outcomes according to PD-L1 expression in the real world. Methods: We retrospectively analyzed mTNBC patients treated with first-line chemotherapy at European Institute of Oncology with evaluable PD-L1 expression. Primary endpoints were Progression-Free Survival (PFS) and Overall Survival (OS) according to PD-L1 expression. Results: From January 2000 to December 2018, 190 patients fulfilled the inclusion criteria for final analysis. PD-L1 positive (≥ 1%) subgroup showed a median PFS of 6.8 vs 5.6 months in PD-L1 negative subgroup (PFS-HR 1.25, 95% CI 0.89–1.74, p-value = 0.191), while at data cutoff we had 120 deaths in the PD-L1 < 1% population with a median OS of 22.1 months and 42 deaths in PD-L1 positive patients with a median OS of 20.8 months (OS-HR 1.09, 95% CI 0.76–1.55, p-value = 0.64). No difference in PFS and OS was related to the choice of chemotherapy (p-value for PFS: 0.19, p-value for OS: 0.53). Conclusion: No differences in clinical outcome were found according to PD-L1 status or chemotherapy regimen chosen. In “unselected” patients, single agent or combination chemotherapy could be appropriate, although in the immunotherapy era patients with newly diagnosed mTNBC should be routinely tested for PD-L1 status. The variability in PD-L1 expression by metastatic site warrants further investigation.

Purpose: To retrospectively review our experience on 84 patients with squamous cell anal canal cancer (SCAC) within 12 months after combined treatment with intensity-modulated RT (IMRT), in terms of acute and early-late toxicity, overall treatment time and interruptions, colostomy-free survival (CFS), and tumor response. Methods: Acute gastrointestinal (GI), genitourinary (GU), and cutaneous (CU) toxicities were assessed according to Common Toxicity Criteria for Adverse Events (CTCAE) version 4.03. Early-late toxicity was scored using the Radiation Therapy Oncology Group (RTOG) late radiation morbidity scoring system. Tumor response was evaluated with response evaluation criteria in solid tumors (RECIST) v1.1. Results: Acute toxicity for 84 subjects (100%): severe (≥ G3) GI and skin toxicity was observed in 4 (5%) and 19 patients (23%), respectively. Early-late toxicity for 73 subjects (87%): severe (≥ G3) GI and vulvo-vaginal toxicity was observed in 2 (3%) and 2 (3%) patients, respectively. No acute or early-late severe GU toxicity was reported. A treatment interruption occurred in 65 patients (77%). CFS was 96% (95% CI 89–99) at 6 months and 92% (95% CI 83–96) at 12 months. At 6 months complete response (CR), partial response (PR) and progressive disease (PD) was observed in 70 (83%), 3 (4%), and 7 patients (8%), respectively. At 12 months, CR was observed in 60 patients (81%); eleven patients (15%) experienced PD. Conclusion: Our study showed an excellent clinical result and very low acute toxicity rates, confirming the IMRT as standard of care for curative treatment of anal cancer patients. The current trial was registered with the number IEO N87/11

To assess the prognostic value of presurgical CA15.3 in a large cohort of patients with early breast cancer. A total of 7.942 consecutive patients with breast cancer operated at the European Institute of Oncology between 1998 and 2005 and with presurgical values of CA 15.3 available were included. We explored patterns of recurrence by baseline CA 15.3 values. Mean CA15.3 was 17.0 U/ml. CA15.3 was associated with age, tumor size, nodal involvement, Ki-67 labeling index, grade, HER2 expression, molecular subtype, and perivascular invasion. CA15.3 was independently associated with distant metastases [HR > 20 U/ml vs. ≤ 20 U/ml: 1.34 (95% CI 1.15-1.56)] and death [HR > 20 U/ml vs. ≤ 20 U/ml: 1.30 (95% CI 1.11-1.53)]. When considering CA15.3 as continuous variable, we observed a constant risk of metastasis and death from the lowest values to about 15-20 U/ml, and then a significantly increasing risk with increasing values of CA15.3. Finally, CA15.3 provided significant additional information to the common prognostic factors to predict the occurrence of metastases (C-index P value 0.04). In patients with operable breast cancer, presurgical CA15.3 value is an independent prognostic factor for metastases and deaths. CA15.3 provides additional information to the common prognostic factors and should be considered in the adjuvant therapeutic algorithm. © 2011 Springer Science+Business Media, LLC.

The aim of this study is to evaluate the outcome of occult breast cancer (OBC) in patients with axillary presentation overall and according to the immunohistochemically defined tumour subtypes. We reviewed information on 15,490 consecutive primary breast cancer patients, who underwent surgery at the European institute of oncology between September 1997 and December 2008. Patients with OBC were compared with an equal number of patients with small invasive breast carcinomas (pT1) observed at the same institution during the same period, matched for year of surgery, age, nodal status and biological features. Eighty patients with OBC (study group) and 80 patients with early breast cancer (control group) were identified. There was no significant difference in the disease-free survival (5 years DFS 66 vs. 68% P = 0.91) and the overall survival (5 years OS 80 and 86% P = 0.99) between the OBC and control groups. A statistically significant worse outcome was observed within the group of OBC for patients with more than four involved lymph nodes and with triple negative tumours. The outcome of OBC patients is comparable with that of matched patients with small sized breast cancer. High risk of relapse and death was observed in OBC patients with triple negative tumours and extensive nodal involvement. © 2011 Springer Science+Business Media, LLC.

Patients with large ER positive tumors candidate to preoperative chemotherapy may also benefit from a concurrent endocrine intervention, but this issue has been scarcely investigated due to concerns arising from unfavorable results emerged from an adjuvant trial of concurrent tamoxifen and chemotherapy. We retrospectively investigated the activity of letrozole plus GnRH analogue (GnRH-a) administered concurrently with preoperative chemotherapy and as adjuvant treatment in premenopausal women with locally advanced ER positive breast cancer consecutively admitted at the European Institute of Oncology. Results were compared with those of a non-randomized unmatched control group of premenopausal women with locally advanced ER positive breast cancer receiving preoperative chemotherapy, followed by tamoxifen and GnRH-a after surgery. Primary endpoints were pathological complete response (pCR) rate, decrease of Ki67 and disease free survival (DFS). One-hundred and nineteen women constituted the study group, while 95 patients served as controls. The pCR rate was 5.0 vs 1.1% in the study and control group, respectively. A statistically significant greater suppression of Ki67 was observed in patients receiving chemoendocrine therapy as compared with controls (P = 0.003). At a median follow up of 59 months, 26 events occurred in the chemoendocrine group and 48 in the control group. Five-year DFS was 78 vs 41% in the study and in the control group, respectively [adjusted HR 0.46, 95% CI 0.27-0.79, P = 0.0047]. The concurrent administration of letrozole and GnRH-a with preoperative chemotherapy was highly effective in premenopausal women with large ER positive breast cancer in terms of decreased proliferation and of improved DFS. Randomized studies are warranted to establish the role of the addition of endocrine therapy to chemotherapy as standard preoperative approach for ER positive locally advanced breast cancer as well as of letrozole in combination with GnRH-a for the treat

AIMS/HYPOTHESIS: Post-prandial glucose may be a risk factor for cardiovascular disease and chronic diabetic complications. We tested the hypothesis that post-prandial hyperglycaemia is common in type 2 diabetes, even among patients in apparently good glycaemic control, and that simple clinical characteristics identify subsets of diabetic patients with frequent post-prandial hyperglycaemia. SUBJECTS AND METHODS: Three self-assessed daily blood glucose profiles over a 1-week period, including 18 glucose readings before and 2 h after meals, were obtained from 3,284 unselected outpatients (men 51%; age 63+/-10 years) with non-insulin-treated type 2 diabetes mellitus attending 500 different diabetes clinics operating throughout Italy. RESULTS: A post-prandial blood glucose value >8.89 mmol/l (160 mg/dl) was recorded at least once in 84% of patients, and 81% of patients had at least one Delta glucose > or =2.22 mmol/l (40 mg/dl). Among patients with apparently good metabolic control, 38% had >40% of post-prandial blood glucose readings >8.89 mmol/l (> or =4 of 9 meals in total), and 36% had >40% Delta glucose > or =2.22 mmol/l. In multivariate analysis adjusted for pre-prandial glucose levels, older age, longer duration of diabetes, absence of obesity, hyperlipidaemia and hypertension, as well as treatment with sulfonylureas, were significantly associated with greater glucose excursions after meals. CONCLUSIONS/INTERPRETATION: These results indicate that post-prandial hyperglycaemia is a very frequent phenomenon in patients with type 2 diabetes mellitus on active treatment; can occur even when metabolic control is apparently good; and can be predicted by simple clinical features.

Several experimental studies have suggested that specific nutrients might play a role on the risk of liver damage. Nevertheless, few epidemiological studies have evaluated the role of diet on the risk of symptomatic liver cirrhosis, giving contradictory results. To evaluate the role of the intake of nutritional factors and dietary patterns on the risk of symptomatic liver cirrhosis and to examine their combined action with alcohol consumption we used data from the Italian Study on Liver Cirrhosis Determinants project. From 1994 to 1998 all the consecutive cirrhotic inpatients admitted to 19 Italian collaborative hospitals for signs of liver decompensation in whom the diagnosis of liver cirrhosis was made for the first time (259 cases) and one or two gender, age and area of residence matched individuals (416 controls) were recruited. Data on lifetime alcohol intake, usual consumption of 191 food items and on markers of hepatitis B and C viral infection were collected. The analysis of principal components identified a nutritional pattern positively correlated with vegetable and fruit intakes and negatively with animal and no-fruit sugar products. With respect to abstainers, relative risks in consumers of use < or = 25 and > or = 51 g/day of alcohol increased from 0.4 [95% confidence interval 0.0, 5.9] to 9.3 [1.3, 69.0] and from 2.1 [1.1, 4.2] to 18.1 [2.8, 118.3] for the lowest and the highest value of this nutritional pattern, respectively. Diet might therefore modulate the damaging effect of alcohol on the liver.
