Abstract
INTRODUCTION The Coronavirus Disease 2019 (COVID-19) has disrupted health services worldwide. The evidence on the impact of the pandemic on cancer care provision, however, is conflicting. We aimed to audit the management of patients diagnosed with early breast cancer (EBC) during the pandemic in a large, tertiary-level cancer center in Italy. METHODS We conducted a cross-sectional study to track the route to first treatment for patients diagnosed with EBC during 2019, 2020, and 2021. We abstracted data for all consecutive patients referred to the Veneto Institute of Oncology (Padua, Italy). We defined as point of contact (POC) the date of the first consultation with a breast cancer specialist of the breast unit. First treatment was defined as either upfront surgery or neoadjuvant chemotherapy (NACT). RESULTS We reviewed medical records for 878 patients for whom an MDT report during 2019-2021 (April through June) was available. Of these, 431 (49%) were eligible. The proportion of screen-detected tumors was larger in 2019 and 2021 than in 2020 (59%). Conversely, the proportion of screen-detected tumors was offset by the proportion of palpable tumors in 2020 (P = .004). Distribution of tumor and nodal stage was unchanged over time, but in situ tumors were slightly fewer in 2020 than in 2019 or 2021. The adjusted odds ratio for treatment delay (45 days or more) was 0.87 for 2020 versus 2019 (95% CI, 0.5-1.53) and 0.9 for 2021 versus 2019 (95% CI, 0.52-1.55). CONCLUSIONS There was no evidence for major changes in the management of patients with EBC during 2019-2021 and no treatment delays were observed. Our findings suggest that more women presented with palpable nodules at diagnosis, but the stage distribution did not change over time. Validation on a larger cohort of patients is warranted to robustly assess the impact of the COVID-19 pandemic on treatment practices for patients with EBC.

Abstract
BACKGROUND Breast-conserving surgery (BCS) still remains a blind surgery despite all available tumor localization methods. Intraoperative ultrasound (IOUS) allows real-time visualization during all resection phases. METHODS This was a prospective observational cohort study conducted at the Veneto Institute of Oncology between January 2021 and June 2022. Patients with ductal carcinoma in situ, T1-2 invasive cancer, or post-neoadjuvant tumors, suitable for BCS, were recruited. All breast cancer lesion types were included, i.e. solid palpable, solid non-palpable, non-solid non-palpable, and post-neoadjuvant treatment residual lesions. Eligible participants were randomly assigned to either IOUS or traditional surgery (TS) in a 1:1 ratio. The main outcomes were surgical margin involvement, reoperation rate, closest margin width, main specimen and cavity shaving margin volumes, excess healthy tissue removal, and calculated resection ratio (CRR). RESULTS Overall, 160 patients were enrolled: 80 patients were allocated to the TS group and 80 to the IOUS group. IOUS significantly reduced specimen volumes (16.8 cm3 [10.5-28.9] vs. 24.3 cm3 [15.0-41.3]; p = 0.015), with wider closest resection margin width (2.0 mm [1.0-4.0] vs. 1.0 mm [0.5-2.0] after TS; p < 0.001). Tumor volume to specimen volume ratio was significantly higher after IOUS (4.7% [2.5-9.1] vs. 2.9% [0.8-5.2]; p < 0.001). IOUS yielded significantly better CRR (84.5% [46-120.8] vs. 114% [81.8-193.2] after TS; p < 0.001), lower involved margin rate (2.5 vs. 15%; p = 0.009) and reduced re-excision rate (2.5 vs. 12.5%; p = 0.032). CONCLUSIONS IOUS allows real-time resection margin visualization and continuous control during BCS. It showed clear superiority over TS in both oncological and surgical outcomes for all breast cancer lesion types. These results disfavor the paradigm of blind breast surgery.

Abstract
The impact of the COVID19 pandemic on treatment practices for patients diagnosed with early breast cancer: a cross-sectional study from a large comprehensive cancer centre in Italy.
Introduction: The Coronavirus Disease 2019 (COVID19) has disrupted health services worldwide. The evidence on the impact of the pandemic on cancer care provision, however, is conflicting. Some reports found that management for patients diagnosed with early breast cancer (EBC) during the pandemic did not differ from pre-pandemic practices; other reports suggested that delays in breast cancer surgery may have occurred. We aimed to audit the management of patients diagnosed with EBC during the pandemic in a large, tertiary-level cancer centre in Italy.
Methods: We conducted a cross-sectional study to track the route to first treatment for patients diagnosed with EBC during 2019, 2020, and 2021. We abstracted data for all consecutive patients referred to the Veneto Institute of Oncology (Padua, Italy). We defined as point of contact (POC) the date of the first consultation with a breast cancer specialist of the breast unit. We considered patients with a first POC in the 6 months preceding the multidisciplinary (MDT) meeting and initiating a treatment within 6 months from the POC. We chose the 3-month period April-June because in 2020 it was when health services were first acutely disrupted. We analysed the same period for 2019 and 2021. First treatment was defined as either upfront surgery or neoadjuvant chemotherapy (NACT). The time to first treatment was defined as the interval between the first POC and the first treatment. We used the median time to first treatment in 2019 to define the threshold for treatment delay.
Results: We reviewed medical records for 878 patients for whom an MDT report during 2019-2021 (April through June) was available. Of these, 431 (49%) were eligible: 144 in 2019, 127 in 2020 and 150 in 2021. Median age at first POC was 61 years. The proportion of screen-detected tumours was larger in 2019 and 2021 than in 2020 (59%). Conversely, the proportion of screen-detected tumours was offset by the proportion of palpable tumours in 2020 (44% versus 56%). These differences were statistically significant (chi-square test 11.12, p=0.004). Distribution of tumour and nodal stage was unchanged over time, but in-situ tumours were slightly fewer in 2020 than in 2019 or 2021. The odds ratio for treatment delay (45 days or more) was 0.87 for 2020 versus 2019 (95% CI, 0.5-1.53) and 0.9 for 2021 versus 2019 (95% CI, 0.52-1.55), after adjusting for type of POC, presentation with symptoms, treatment type, tumour stage, nodal stage, and EBC subtype (i.e., luminal, HER2-positive, triple-negative).
Conclusions: There was no evidence for major changes in the management of EBC patients during 2019-2021 and no treatment delays were observed. However, our results show a slight decrease in the absolute number of patients being treated in 2020, offset by an increase in 2021 to levels comparable to 2019. Our findings suggest that disruption of breast cancer screening programmes may have impacted on the characteristics of the patient population, with a larger proportion of women presenting with palpable nodules. Validation on a larger, population-based cohort of patients is warranted to robustly assess the impact of the COVID19 pandemic on treatment practices and outcome for EBC patients.

Visuospatial Deficits Are Associated with Pisa Syndrome and not Camptocormia in Parkinson's Disease. Mov Disord Clin Pract 2023; 10:64-73.

Abstract
Background Pisa syndrome (PS) and camptocormia (CC) are postural abnormalities frequently associated with Parkinson's disease (PD). Their pathophysiology remains unclear, but the role of cognitive deficits has been postulated. Objectives To identify differences in the neuropsychological functioning of patients with PD with PS or CC compared with matched patients with PD without postural abnormalities. Methods We performed a case-control study including 57 patients with PD with PS (PS+) or CC (CC+) and 57 PD controls without postural abnormalities matched for sex, age, PD duration, phenotype, and stage. Patients were divided into four groups: PS+ (n = 32), PS+ controls (PS-, n = 32), CC+ (n = 25), and CC+ controls (CC-, n = 25). We compared PS+ versus PS- and CC+ versus CC- using a neuropsychological battery assessing memory, attention, executive functions, visuospatial abilities, and language. Subjective visual vertical (SVV) perception was assessed by the Bucket test as a sign of vestibular function; the misperception of trunk position, defined as a mismatch between the objective versus subjective evaluation of the trunk bending angle >5°, was evaluated in PS+ and CC+. Results PS+ showed significantly worse visuospatial performances (P = 0.025) and SVV perception (P = 0.038) than their controls, whereas CC+ did not show significant differences compared with their control group. Reduced awareness of postural abnormality was observed in >60% of patients with PS or CC. Conclusions Low visuospatial performances and vestibular tone imbalance are significantly associated with PS but not with CC. These findings suggest different pathophysiology for the two main postural abnormalities associated with PD and can foster adequate therapeutic and prevention strategies.

Abstract
BACKGROUND Delirium is thought to be common across various settings of care; however, still little research has been conducted in rehabilitation. AIM We investigated the prevalence of delirium, its features and motor subtypes in older patients admitted to rehabilitation facilities during the three editions of the "Delirium Day project". METHODS We conducted a cross-sectional study in which 1237 older patients (age ≥ 65 years old) admitted to 50 Italian rehabilitation wards during the three editions of the "Delirium Day project" (2015 to 2017) were included. Delirium was evaluated through the 4AT and its motor subtype with the Delirium Motor Subtype Scale. RESULTS Delirium was detected in 226 patients (18%), and the most recurrent motor subtype was mixed (37%), followed by hypoactive (26%), hyperactive (21%) and non-motor one (16%). In a multivariate Poisson regression model with robust variance, factors associated with delirium were: disability in basic (PR 1.48, 95%CI: 1.17-1.9, p value 0.001) and instrumental activities of daily living (PR 1.58, 95%CI: 1.08-2.32, p value 0.018), dementia (PR 2.10, 95%CI: 1.62-2.73, p value < 0.0001), typical antipsychotics (PR 1.47, 95%CI: 1.10-1.95, p value 0.008), antidepressants other than selective serotonin reuptake inhibitors (PR 1.3, 95%CI: 1.02-1.66, p value 0.035), and physical restraints (PR 2.37, 95%CI: 1.68-3.36, p value < 0.0001). CONCLUSION This multicenter study reports that 2 out 10 patients admitted to rehabilitations had delirium on the index day. Mixed delirium was the most prevalent subtype. Delirium was associated with unmodifiable (dementia, disability) and modifiable (physical restraints, medications) factors. Identification of these factors should prompt specific interventions aimed to prevent or mitigate delirium.

The association between low skeletal muscle mass and delirium: results from the nationwide multi-centre Italian Delirium Day 2017. Aging Clin Exp Res 2022; 34:349-357.

Abstract
Introduction Delirium and sarcopenia are common, although underdiagnosed, geriatric
syndromes. Several pathological mechanisms can link delirium and low skeletal muscle mass, but few studies have investigated their association. We aimed to investigate (1) the association between delirium and low skeletal muscle mass and (2) the possible role of calf circumference mass in finding cases with delirium. Methods The analyses were conducted employing the cross-sectional “Delirium Day” initiative, on patient 65 years and older admitted to acute hospital medical wards, emergency departments, rehabilitation wards, nursing homes and hospices in Italy in 2017. Delirium was diagnosed as a 4 + score at the 4-AT scale. Low skeletal muscle mass was operationally defined as calf circumference ≤ 34 cm in males and ≤ 33 cm in females. Logistic regression models were used to investigate the association between low skeletal muscle mass and delirium. The discriminative ability of calf circumference was evaluated using non-parametric ROC analyses. Results A sample of 1675 patients was analyzed. In total, 73.6% of participants had low skeletal muscle mass and 24.1% exhibited delirium. Low skeletal muscle mass and delirium showed an independent association (OR: 1.50; 95% CI 1.09–2.08). In the subsample of patients without a diagnosis of dementia, the inclusion of calf circumference in a model based on age and sex significantly improved its discriminative accuracy [area under the curve (AUC) 0.69 vs 0.57, p < 0.001]. Discussion and conclusion Low muscle mass is independently associated with delirium. In patients without a previous diagnosis of dementia, calf circumference may help to better identify those who develop delirium.

Abstract
AIM OF THE STUDY Nomograms have been proposed to assess prognosis following curative surgery for gastric cancer. The objective of the current study was to evaluate the performance of the Gastric Cancer Collaborative Group nomograms developed in 2014 by Kim et al., using a cohort of patients from a 10-year single institution experience in gastric cancer management. PATIENTS AND METHODS We retrospectively reviewed patients who underwent curative-intent surgery for histologically confirmed gastric cancer at First Surgical Clinic of Padua University Hospital (Italy) from January 2010 to May 2020. Univariable and multivariable Cox proportional hazard models were employed to assess the effect of the variables of interest on mortality and recurrence. Multivariable analysis was performed by considering the variables included in the Gastric Cancer Collaborative Group nomograms in order to validate them. The performance of the nomograms was evaluated using Harrell's C-index and calibration plots. RESULTS Overall, 168 patients were included, with a median follow-up of 20.1 months. On multivariable analysis, tumor location, lymph node ratio, and pathological T stage were associated with recurrence; age, tumor location, lymph node ratio, and pT stage were associated with OS (overall survival). The nomograms had good discriminatory capability to classify both OS (C-index: 0.75) and DFS (disease-free survival) (C-index 0.72). The corrected C-Index for DFS based on the AJCC staging system revealed better prediction (C-Index 0.75), while the corrected C-Index for OS had worse discrimination ability compared with the current nomogram (C-Index 0.72). CONCLUSIONS The Gastric Cancer Collaborative Group nomograms demonstrated good performances in terms of prediction of both OS and DFS on external validation. The two nomograms are easy to apply, and variables included are widely available to most facilities.

Impact of estrogen receptor levels on outcome in non-metastatic triple negative breast cancer patients treated with neoadjuvant/adjuvant chemotherapy. NPJ Breast Cancer 2021; 7:101.

Abstract
Although 1% is the recommended cut-off to define estrogen receptor (ER) positivity, a 10% cut-off is often used in clinical practice for therapeutic purposes. We here evaluate clinical outcomes according to ER levels in a monoinstitutional cohort of non-metastatic triple-negative breast cancer (BC) patients undergoing (neo)adjuvant chemotherapy. Clinicopathological data of 406 patients with ER < 10% HER2-negative BC treated with (neo)adjuvant chemotherapy between 01/2000 and 04/2019 were collected. Patients were categorized in ER-negative (ER < 1%; N = 364) and ER-low positive (1-9%, N = 42). At a median follow-up of 54 months, 88 patients had relapsed and 64 died. No significant difference was observed in invasive relapse-free survival (iRFS) and overall survival (OS) according to ER expression levels, both at univariate and multivariate analysis (5-years iRFS 74.0% versus 73.1% for ER-negative and ER-low positive BC, respectively, p = 0.6; 5-years OS 82.3% versus 76.7% for ER-negative and ER-low positive BC, respectively, p = 0.8). Among the 165 patients that received neoadjuvant chemotherapy, pathological complete response rate was similar in the two cohorts (38% in ER-negative, 44% in ER-low positive, p = 0.498). In conclusion, primary BC with ER1-9% shows similar clinical behavior to ER 1% BC. Our results suggest the use of a 10% cut-off, rather than <1%, to define triple-negative BC.

Abstract
An individual prediction of DFS and OS may be useful after surgery for gastric cancer to inform patients and to guide the clinical management. Patients who underwent curative-intent resection for gastric cancer between January 2010 and May 2020 at a single Italian institution were identified. Variables associated with OS and DFS were recorded and analysed according to univariable and multivariable Cox models. Nomograms predicting OS and DFS were built according to variables resulting from multivariable Cox models. Discrimination ability was calculated using the Harrell’s Concordance Index. Overall, 168 patients underwent curative-intent resection. Nomograms to predict OS were developed including age, tumor size, tumor location, T stage, N stage, M stage and post-operative complications, while nomogram to predict DFS includes Lauren classification, and lymph node ratio (LNR). On internal validation, both nomograms demonstrated a good discrimination with a Harrell’s C-index of 0.77 for OS and 0.71 for DFS. The proposed nomogram to predict DFS and OS after curative-intent surgery for gastric cancer showed a good discrimination on internal validation, and may be useful to guide clinician decision-making, as well help identify patients with high-risk of recurrence or with a poor estimated survival.

Abstract
BACKGROUND No predictive markers for chemotherapy activity have been validated in gastric cancer (GC). The potential value of class III β-tubulin (TUBB3) as biomarker for prognosis and resistance to taxane-based therapy was reported. METHODS We analyzed GC samples of patients enrolled in the Intergroup Trial of Adjuvant Chemotherapy in Adenocarcinoma of the Stomach (ITACA-S), a randomized adjuvant study comparing 5-fluorouracil/leucovorin (5-FU/LV) and docetaxel-based sequential chemotherapy. TUBB3 was quantitated by selected reaction monitoring mass spectrometry and patients were stratified using a threshold of 750 attomoles per microgram (amol/µg). Cox proportional modeling and Kaplan-Meier survival analysis were used to assess the impact of TUBB3 expression on overall survival (OS) and disease-free survival. RESULTS Patients with TUBB3 protein levels >750 and <750 amol/µg were 21.9% and 78.1%, respectively, and were well-balanced between treatment arms. TUBB3 protein levels were not prognostic. Whereas no survival differences according to the 2 arms were observed in the subgroup with low TUBB3 expression (5-year OS 47% vs 40%; p = 0.44), patients with high TUBB3 had a clinically meaningful poorer OS when receiving docetaxel-based versus 5-FU/LV chemotherapy (5-year OS 31% vs 54%; p = 0.09), with a statistically significant interaction between TUBB3 and treatment (p = 0.049). CONCLUSIONS The quantification of TUBB3 might be considered as a negative predictive biomarker of benefit from taxane-based therapy in GC. Studies are needed to evaluate its role in the neoadjuvant setting.

[PMID: 31569921 PMCID: PMC6813900 DOI: 10.3344/kjp.2019.32.4.286] [Citation(s) in RCA: 33] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2019] [Revised: 07/28/2019] [Accepted: 07/29/2019] [Indexed: 01/25/2023] Open
Abstract
Background Breast cancer is complicated by a high incidence of chronic postoperative pain (25%–60%). Regional anesthesia might play an important role in lowering the incidence of chronic pain; however it is not known if the pectoral nerve block (PECS block), which is commonly used for breast surgery, is able to prevent this complication. Our main objective was therefore to detect any association between the PECS block and chronic pain at 3, 6, 9, and 12 months in patients undergoing breast surgery. Methods We conducted a prospective, monocentric, observational study. We enrolled 140 consecutive patients undergoing breast surgery and divided them in patients receiving a PECS block and general anesthesia (PECS group) and patients receiving only general anesthesia (GA group). Then we considered both intraoperative variables (intravenous opioids administration), postoperative data (pain suffered by the patients during the first 24 postoperative hours and the need for additional analgesic administration) and development and persistence of chronic pain (at 3, 6, 9, and 12 mo). Results The PECS group had a lower incidence of chronic pain at 3 months (14.9% vs. 31.8%, P = 0.039), needed less intraoperative opioids (fentanyl 1.61 μg/kg/hr vs. 3.3 μg/kg/hr, P < 0.001) and had less postoperative pain (3 vs. 4, P = 0.017). Conclusions The PECS block might play an important role in lowering incidence of chronic pain, but further studies are needed.

Abstract
BACKGROUND The incidence of cholelithiasis has been shown to be higher for patients after gastrectomy than for the general population, due to vagal branch damage and gastrointestinal reconstruction. The aim of this trial was to evaluate the need for routine concomitant prophylactic cholecystectomy (PC) during gastrectomy for cancer. METHODS A multicenter, randomized, controlled trial was conducted between November 2008 and March 2017. Of the total 130 included patients, 65 underwent PC and 65 underwent standard gastric surgery only for curable cancers. The primary endpoint was cholelithiasis-free survival after gastrectomy for gastric adenocarcinoma. Cholelithiasis was detected by ultrasound exam. RESULTS After a median follow-up of 62 months, eight patients (12.3%) in the control group developed biliary abnormalities (four cases of gallbladder calculi and four cases of biliary sludge), with only three (4.6%) being clinically relevant (two cholecystectomies needed, one acute pancreatitis). One patient in the PC group had asymptomatic biliary dilatation during sonography after surgery. The cholelithiasis-free survival did not show statistical significance between the two groups (P = 0.267). The number needed to treat with PC to avoid reoperation for cholelithiasis was 1:32.5. CONCLUSIONS Concomitant PC during gastric surgery for malignancies, although reducing the absolute number of biliary abnormalities, has no significant impact on the natural course of patients.

Abstract
Aim To evaluate the accuracy of magnetic resonance imaging in assessing tumor response following neoadjuvant chemotherapy in patients with locally advanced breast cancer. Materials and Methods Twenty-six patients entered a phase II study of neoadjuvant chemotherapy, undergoing bilateral breast magnetic resonance imaging before therapy and before surgery. Tumor response was classified using RECIST criteria, using tumor size at magnetic resonance imaging. The latter was then compared to residue found at histopathological examination. Results Magnetic resonance imaging showed 6 (23%) complete responses, 17 (65%) partial responses, 3 (11.5%) disease stabilizations and no disease progressions. Twenty-three tumors (88.5%) were considered responsive and 3 (11.5%) unresponsive. Pathological tumor response was: 6 complete responses (23%), 17 partial responses (65%), 2 stable disease (8%), 1 progression (4%). When results of the preoperative magnetic resonance imaging were compared to pathological tumor response, magnetic resonance imaging overestimated tumor size in 12 cases (46%) and underestimated it in 9 (35%). However, preoperative magnetic resonance imaging failed to detect invasive tumor in 2 false-negative cases (8%), 1 of which was multifocal. Mastectomy was performed in 12 cases: 1 case of disease progression even though the neoplasm appeared smaller at magnetic resonance imaging, 3 cases with stable disease, and 4 cases with T3 or T4 disease. The 9th patient was T2N2 with initial retroareolar disease and negative magnetic resonance imaging after chemotherapy. The 10th patient, affected by lobular cancer, was in partial remission but was T3N1. The 11th patient was 57 years old but was not interested in conservative surgery. The 12th patient requested bilateral prophylactic mastectomy due to her positive family history of breast cancer. Conclusions Magnetic resonance imaging of the breast allowed conservative surgery in 54% of the patients. This low value is primarily due to overestimation of tumor size, with a negative predictive value of 67% in our population. However, surgeons were able to choose conservative surgery with relative safety in cases of small residual disease.

Abstract
PURPOSE To investigate clinical factors influencing the prognosis of patients submitted to hepatectomy for metastases from gastric cancer and their clinical role. METHODS Retrospective multi-center chart review. We evaluated how survival from surgery was influenced by patient-related, gastric cancer-related, metastasis-related and treatment-related candidate prognostic factors. RESULTS One hundred and five patients submitted to hepatectomy for metastases from gastric cancer, in the synchronous and metachronous setting of the disease. In 89 cases a R0 resection was achieved, while in 16 a R+ hepatic resection was performed. Adjuvant chemotherapy was administered to 29 patients. Surgical mortality was 1% and morbidity 13.3%. Median disease-free survival was 10 months, median overall survival was 14.6 months. Overall 1, 3, and 5-year survival rates were 58.2%, 20.3%, and 13.1%, respectively. Survival was influenced independently by the factor T of the gastric primary (p < 0.001), by the curativity of surgical procedure (p = 0.001), by the timing of hepatic involvement (p < 0.001) and by adjuvant chemotherapy (p < 0.001). T4 gastric cancer, R+ resection, synchronous metastases, and abstention from adjuvant chemotherapy were associated with a worse prognosis; T4 gastric cancer and R+ resections displayed a cumulative effect (p < 0.001). CONCLUSIONS Our data show that R0 resection must be pursued whenever possible. Furthermore, in the synchronous setting, the coexistence of T4 gastric primaries and R+ resections suggests prudence and probably abstention from hepatectomy. Finally, a multimodal treatment associating surgery and chemotherapy offers the best survival results.

Surgical management of duodenal stump fistula after elective gastrectomy for malignancy: an Italian retrospective multicenter study. Gastric Cancer 2016; 19:273-9.

Abstract
BACKGROUND Duodenal stump fistula (DSF) is a severe complication of gastrectomy. Although nonsurgical therapy is preferred, surgery is still mandatory in one third of DSF patients. The aim of this article is to analyze the surgical management of DSF and factors related to its outcome. METHODS We performed a retrospective multicenter study using data from January 1990 to November 2011 in 16 Italian surgery centers. We collected 8,268 elective gastrectomies for malignancies, 7,987 by the laparotomic and 281 by the laparoscopic approach. Two hundred five patients developed a DSF, 75 of whom underwent surgery for DSF. We analyzed mortality and DSF healing time as well as the impact of clinical, oncological, and surgical characteristics. RESULTS The laparoscopic approach increased the risk of DSF development (odds ratio 5.6, 95% confidence interval 2.7-10.6, P < 0.001). The indication for first DSF surgery was intra-abdominal sepsis; the failure rate was over 30%, associated with the appearance of fistulas of neighboring organs, bleeding, and the need for reoperations. The mortality rate was 28% and was related to the presence of vascular disease (P = 0.04), more than one reoperation (P = 0.05), sepsis (P < 0.001), and renal failure (P < 0.001). Fifty-four patients recovered after a median of 39 days (interquartile range 22-68 days); the need to perform more reoperations (P < 0.01) and the presence of an abdominal abscess (P < 0.01) led to an increase in healing time. CONCLUSIONS Surgery for DSF has a poor prognosis. Our data will help to identify patients at risk of death, but unfortunately could not establish the best surgical procedure applicable to all cases of DSF.

Sentinel node biopsy performance after neoadjuvant chemotherapy in locally advanced breast cancer: A systematic review and meta-analysis. Int J Cancer 2015; 138:472-80.

Abstract
The use of sentinel node biopsy (SNB) after neoadjuvant chemotherapy (NAC) in patients with locally advanced breast cancer is debated. Our aim was to quantitatively review the available evidence on the performance of SNB after NAC in patients with locally advanced breast cancer. We performed a systematic review (by searching the PubMed, Cochrane and Scopus databases) and random effects meta-analysis to investigate on the feasibility and accuracy of SNB in these patients. The two outcomes of interest were the sentinel node identification rate (SIR) and the false negative rate (FNR). Sensitivity analysis and meta-regression were used to investigate the potential sources of between-study heterogeneity. We retrieved 72 eligible studies enrolling 7,451 patients. Upon meta-analysis, summary SIR resulted 89.6% [95% confidence interval (CI): 87.8-91.2; heterogeneity I(2): 76.9%], which poorly compares with the 95% SIR observed in some recent series of early breast cancer. The summary FNR resulted 14.2% (CI: 12.5-16.0; heterogeneity I(2): 29.1%), which was significantly higher than the 8-10% reference value. Considering an average post-NAC lymph node positivity rate of 50%, the downstaging due to false negative SNB would occur in 7/100 patients (with an excess error rate of 2-3/100 as compared to the early-stage setting). No plausible source of between-study heterogeneity was found. Based on the largest series of studies ever meta-analyzed, our findings highlight the limits of SNB performance in this population, where the impact of SNB on patient survival is still to be defined.

Short-term and long-term risk factors in gastric cancer. World J Gastroenterol 2015; 21:6434-43.

Abstract
While in chronic diseases, such as diabetes, mortality rates slowly increases with age, in oncological series mortality usually changes dramatically during the follow-up, often in an unpredictable pattern. For instance, in gastric cancer mortality peaks in the first two years of follow-up and declines thereafter. Also several risk factors, such as TNM stage, largely affect mortality in the first years after surgery, while afterward their effect tends to fade. Temporal trends in mortality were compared between a gastric cancer series and a cohort of type 2 diabetic patients. For this purpose, 937 patients, undergoing curative gastrectomy with D1/D2/D3 lymphadenectomy for gastric cancer in three GIRCG (Gruppo Italiano Ricerca Cancro Gastrico = Italian Research Group for Gastric Cancer) centers, were compared with 7148 type 2 diabetic patients from the Verona Diabetes Study. In the early/advanced gastric cancer series, mortality from recurrence peaked to 200 deaths per 1000 person-years 1 year after gastrectomy and then declined, becoming lower than 40 deaths per 1000 person-years after 5 years and lower than 20 deaths after 8 years. Mortality peak occurred earlier in more advanced T and N tiers. At variance, in the Verona diabetic cohort overall mortality slowly increased during a 10-year follow-up, with ageing of the type 2 diabetic patients. Seasonal oscillations were also recorded, mortality being higher during winter than during summer. Also the most important prognostic factors presented a different temporal pattern in the two diseases: while the prognostic significance of T and N stage markedly decrease over time, differences in survival among patients treated with diet, oral hypoglycemic drugs or insulin were consistent throughout the follow-up. Time variations in prognostic significance of main risk factors, their impact on survival analysis and possible solutions were evaluated in another GIRCG series of 568 patients with advanced gastric cancer, undergoing curative gastrectomy with D2/D3 lymphadenectomy. Survival curves in the two different histotypes (intestinal and mixed/diffuse) were superimposed in the first three years of follow-up and diverged thereafter. Likewise, survival curves as a function of site (fundus vs body/antrum) started to diverge after the first year. On the contrary, survival curves differed among age classes from the very beginning, due to different post-operative mortality, which increased from 0.5% in patients aged 65-74 years to 9.9% in patients aged 75-91 years; this discrepancy later disappeared. Accordingly, the proportional hazards assumption of the Cox model was violated, as regards age, site and histology. To cope with this problem, multivariable survival analysis was performed by separately considering either the first two years of follow-up or subsequent years. Histology and site were significant predictors only after two years, while T and N, although significant both in the short-term and in the long-term, became less important in the second part of follow-up. Increasing age was associated with higher mortality in the first two years, but not thereafter. Splitting survival time when performing survival analysis allows to distinguish between short-term and long-term risk factors. Alternative statistical solutions could be to exclude post-operative mortality, to introduce in the model time-dependent covariates or to stratify on variables violating proportionality assumption.

External Validation of a Score Predictive of Recurrence after Radical Surgery for Non-Cardia Gastric Cancer: Results of a Follow-Up Study. J Am Coll Surg 2015; 221:280-90.

Abstract
BACKGROUND A score predictive of tumor recurrence after radical surgery for non-cardia gastric cancer was previously developed in Italian centers. The aim of this study was to validate the score in a consecutive cohort with prospectively collected follow-up data. STUDY DESIGN Of 1,178 patients surgically treated between 1998 and 2006, six hundred and thirty-five patients who fulfilled the selection criteria and completed the follow-up program were available for analysis. The score value for each patient was calculated using the formula obtained from a logistic regression model. Discrimination and calibration of the score in the validation group were evaluated and compared with the data of 438 patients in the study group where the score was developed. RESULTS Most patients in both groups had very low or very high score values. In the validation group, the observed recurrence rates ranged from 5% to 92% in different score strata. The area under the receiver operating characteristic curve was 0.889 (95% CI, 0.864-0.914; p < 0.001), indicating a high discrimination value of the score for recurrence. A good calibration was observed by comparing the predicted risk with the actual risk of recurrence. With a score cut-off value of 50, sensitivity, specificity, and overall accuracy were 74%, 86%, and 81%, respectively. An inverse correlation between the time to recurrence and score level was also estimated (R(2) = 0.119; p < 0.001). CONCLUSIONS The high predictive value of the score was validated in a consecutive cohort. These results might allow the introduction of the score in clinical practice for Western patients.

Abstract
PURPOSE Management of patients with synchronous hepatic metastases as the sole metastatic site at diagnosis of gastric cancer is debated. We studied a cohort of patients admitted to surgical units, investigating prognostic factors of clinical relevance and the results of various therapeutic strategies. METHODS Retrospective multicentre chart review. We evaluated how survival from surgery was influenced by patient-related, gastric cancer-related, metastasis-related and treatment-related candidate prognostic factors. RESULTS Forty-four patients received palliative surgery without resection, 98 palliative gastrectomy (in 16 cases associated with R+ hepatectomy), whereas 53 patients received both curative gastrectomy and hepatic resection(s) (R0). Adjuvant chemotherapy was administered to 44 patients. Therapeutic approach was selected on the basis of extension of disease, patient's general conditions and surgeon's attitude. Surgical mortality was 4.6 % and morbidity was 17.4 %. Survival was independently influenced by the factor T of the gastric primary (p = 0.036) and by the degree of hepatic involvement (p = 0.010). T > 2 and H3 liver involvement were associated with worse prognosis with cumulative effect (p = 0.002). Therapeutic approach to the metastases (p = 0.009) and adjuvant chemotherapy (p < 0.001) displayed independent impact upon survival, with benefit for those receiving aggressive multimodal treatment. The 1-, 3-, and 5-year survival rates were 50.4, 14.0, and 9.3 %, respectively, for patients submitted to curative surgery, 16, 8.5, and 4.3 % after palliative gastrectomy, and 6.8, 2.3, and 0 % after palliative surgery without resection. CONCLUSIONS Our data suggest some clinical criteria that may facilitate selection of candidates to curative surgery, which offers the best survival chances, especially when associated with adjuvant chemotherapy.

Abstract
BACKGROUND Gastric stump carcinoma (GSC) has been studied after primary gastrectomy for benign disease but few studies have evaluated its correlation with gastric cancer. PATIENTS We assessed 541 patients submitted to subtotal gastrectomy for early gastric cancer at least 15 years ago. RESULTS GSC was diagnosed in 16 (2.9%) patients, giving a 4% cumulative risk of GSC 20 years after surgery. Diagnosis was made within 5 years of surgery in 10 patients and after 8 years in 6 cases. GSC occurred in 13/470 (2.8%) patients submitted to Billroth 2 reconstruction, 2/30 (6.7%) patients who underwent Billroth 1, and 1/41 (2.4%) patients after Roux-en-Y reconstruction. Significant risk factors observed for GSC were histologic type and sex. Other synchronous or metachronous extragastric tumors were registered in 56 (11.2%) patients. CONCLUSIONS The risk of GSC was low, even 20 years after subtotal gastrectomy for early gastric cancer. Lauren intestinal histotype and male sex were frequently associated with GSC. No correlation was observed between GSC and reconstruction technique or multifocality. Clinically speaking, GSC could be considered a subset of gastric cancer.

Abstract
BACKGROUND Some trial have demonstrated a benefit of adjuvant fluoropirimidine with or without platinum compounds compared with surgery alone. ITACA-S study was designed to evaluate whether a sequential treatment of FOLFIRI [irinotecan plus 5-fluorouracil/folinic acid (5-FU/LV)] followed by docetaxel plus cisplatin improves disease-free survival in comparison with 5-FU/LV in patients with radically resected gastric cancer. PATIENTS AND METHODS Patients with resectable adenocarcinoma of the stomach or gastroesophageal junction were randomly assigned to either FOLFIRI (irinotecan 180 mg/m(2) day 1, LV 100 mg/m(2) as 2 h infusion and 5-FU 400 mg/m(2) as bolus, days 1 and 2 followed by 600 mg/m(2)/day as 22 h continuous infusion, q14 for four cycles) followed by docetaxel 75 mg/m(2) day 1, cisplatin 75 mg/m(2) day 1, q21 for three cycles (sequential arm) or De Gramont regimen (5-FU/LV arm). RESULTS From February 2005 to August 2009, 1106 patients were enrolled, and 1100 included in the analysis: 562 in the sequential arm and 538 in the 5-FU/LV arm. With a median follow-up of 57.4 months, 581 patients recurred or died (297 sequential arm and 284 5-FU/LV arm), and 483 died (243 and 240, respectively). No statistically significant difference was detected for both disease-free [hazard ratio (HR) 1.00; 95% confidence interval (CI): 0.85-1.17; P = 0.974] and overall survival (OS) (HR 0.98; 95% CI: 0.82-1.18; P = 0.865). Five-year disease-free and OS rates were 44.6% and 44.6%, 51.0% and 50.6% in the sequential and 5-FU/LV arm, respectively. CONCLUSIONS A more intensive regimen failed to show any benefit in disease-free and OS versus monotherapy. CLINICAL TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT01640782.

Gastric stump cancer after distal gastrectomy for benign disease: clinicopathological features and surgical outcomes. Ann Surg Oncol 2014; 21:2594-600. [PMID: 24639193 DOI: 10.1245/s10434-014-3633-6] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2013] [Indexed: 02/07/2023]
Abstract
PURPOSE The purpose of the present study was to analyze clinicopathologic features and long-term prognosis of gastric stump cancer (GSC) arising in the remnant stomach 5 years or later after partial gastrectomy for benign disease. METHODS We reviewed the results of 176 patients resected with curative intent for GSC at 8 Italian centers belonging to the Italian Research Group for Gastric Cancer (GIRCG). The median (range) follow-up time for surviving patients was 71.2 (6-207) months. RESULTS One hundred forty-six patients were men, the mean age at the time of diagnosis was 69.2 years, and the great majority (167 cases) underwent Billroth II reconstruction. R0 resection was achieved in 158 (90 %) patients, and in 94 (53 %) lymph node dissection was ≥D2. Postoperative mortality and complication rates were 6.2 and 43.2 %, respectively. T1 tumor was diagnosed in 45 (25 %) cases. Lymph node metastases were evident in 86 patients (49 %). Thirteen patients had involvement of the jejunal mesentery nodes (pJN+); five cases were T2-T3 and eight cases were T4. Overall 5-year survival rate was 53.1 %. Five-year survival rates were 68.1, 37.8, and 33.1 % for pT1, pT2-3, and pT4 tumors, respectively (P = 0.001). Five-year survival rate was 56.5 % for node-negative tumors (pN0), 32.3 % for tumors with nodal metastases without involvement of jejunal mesentery nodes (pN+), and 17.1 % for tumors with involvement of jejunal mesentery nodes (pJN+) (P = 0.002). CONCLUSIONS Our study suggests that an aggressive surgical approach can achieve a satisfactory outcome in GSC.

Abstract
BACKGROUND The Italian Research Group for Gastric Cancer supports the practice of follow-up after radical surgery for gastric cancer. METHODS This multicenter, retrospective study (1998-2009) included patients with T1-4N0-3M0 gastric cancer who had undergone D2 gastrectomy and lymphadenectomy, with at least 15 lymph nodes examined, and who had developed recurrent disease. Timing and site of recurrence were correlated to the actual scheduled follow-up timing and modalities. RESULTS From eight centers, 814 patients with recurrent cancer and over 1,754 (46.4 %) patients undergoing gastrectomy were investigated (median follow-up 31 months). The most frequent sites of recurrence were local/regional lymph nodes (35.4 %), liver (24.3 %), peritoneum (30.3 %), lung (10.4 %) and intraluminal (7.5 %). Ninety-four percent of the recurrences were diagnosed within 2 years and 98 % within 3 years. Thoracoabdominal computed tomography (CT) scan and (18)F-fluoro-2-deoxy-D-glucose positron emission tomography (18-FDG-PET) detected more than 90 % of recurrences, abdominal ultrasound detected 70 % and tumor markers detected 40 %, while <10 % were identified by physical examination, chest X-ray, and upper gastrointestinal endoscopy. Twenty-six percent of patients with recurrence were treated, but only 3.2 % were treated with potentially radical intent. CONCLUSION Oncological follow-up after radical surgery for gastric cancer should be focused in the first 3 years, and based mainly on thoracoabdominal CT scan and 18-FDG-PET.

Abstract
IMPORTANCE The role of multivisceral resection, in the setting of locally advanced gastric cancer, is still debated. Previous studies have reported a higher risk for perioperative morbidity and mortality, with limited objective benefit in terms of survival. Conversely, recent studies have shown the feasibility of enlarged resections and the potential advantage of extended resection for clinical stage T4b gastric adenocarcinoma with good long-term results. OBJECTIVE To analyze the role of multivisceral resection for locally advanced gastric cancer with particular attention to the brief and long-term results and to the prognostic value of clinical and pathologic factors. DESIGN Prospective multicenter study using data from between January 1, 1995, and December 31, 2008. SETTINGS Seven Italian surgery centers. PATIENTS A total of 2208 patients underwent curative resections for gastric carcinoma at the centers. Among them, 206 patients presented with a clinical T4b carcinoma. One hundred twelve underwent a combined resection of the adjacent organs with a gastrectomy owing to suspicion or direct invasion of these organs by the gastric cancer. MAIN OUTCOMES AND MEASURES Clinical and pathologic variables were prospectively collected and the feasibility and efficacy of multivisceral resection for locally advanced clinical T4b gastric cancer were assessed. RESULTS Postoperative mortality and complication rates of patients who underwent a gastrectomy with a combined resection of the involved organs were 3.6% and 33.9%, respectively. Pathologic factors revealed that the nodal involvement was present in about 89.3% of patients and the mean (SD) number of pathologic lymph nodes was 14.8 (16.6). The overall 5-year survival rate was 27.2%. The completeness of resection and lymph node invasion represent independent prognostic parameters at multivariate analysis. CONCLUSIONS AND RELEVANCE Our study indicates that patients undergoing extended resections experience acceptable postoperative morbidity and mortality rates, and an en bloc multivisceral resection should be performed in patients when a complete resection can be realistically obtained and when lymph node metastasis is not evident.

The Cholegas Study: safety of prophylactic cholecystectomy during gastrectomy for cancer: preliminary results of a multicentric randomized clinical trial. Gastric Cancer 2013; 16:370-6. [PMID: 22948317 DOI: 10.1007/s10120-012-0195-9] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2012] [Accepted: 08/21/2012] [Indexed: 02/07/2023]
Abstract
BACKGROUND Cholelithiasis is more frequent in patients after gastrectomy, due to dissection of vagal branches and gastrointestinal reconstruction. METHODS A randomized controlled trial was conducted from November 2008 to March 2012. Patients were randomized into two groups: prophylactic cholecystectomy (PC) and standard gastric surgery only (SS) for curable cancers. We planned three end points: evaluation of the number of patients who developed symptoms and needed further surgery for cholelithiasis after standard gastric cancer surgery, evaluation of the incidence of cholelithiasis overall after standard gastric cancer surgery and perioperative complications or costs of prophylactic cholecystectomy. The present study answers to the last end point only. RESULTS After 40 months from the beginning of study, 172 patients were eligible from 9 Centers. Ten patients refused consent and 32 were excluded due to flawing of inclusion criteria (not confirmed adenocarcinomas and no R0 surgery). Therefore, final analysis included 130 patients: 65 in PC group and 65 in SS. Among PC group, 12 patients had surgical complications during the perioperative period; only 1 biliary leakage, conservatively treated, might have been caused by prophylactic cholecystectomy. 6 patients had surgical complications in SS group. One postoperative death occurred in PC group due to pulmonary embolism. Differences were not statistically significant. Similarly, no differences were significant in duration of surgery, blood loss, hospital stay. CONCLUSIONS Concomitant cholecystectomy during standard surgery for gastric malignancies seemed to add no extra perioperative morbidity, mortality and costs to the sample included in the study.

Abstract
e15148 Background: The treatment of these patients is controversial and influenced by personal, often passive, attitude. Knowledge of variables affecting outcome may promote clinical pragmatism.We surveyed the clinical approach to the subset of patients presenting with synchronous hepatic metastases as sole metastatic site at diagnosis of gastric cancer, focusing on the results achieved by different treatments and investigated the prognostic factors of major clinical relevance. Methods: Retrospective multi-centre chart review evaluating 210 patients admitted in surgical units. We studied how survival from surgery or diagnosis was influenced by different patient-related, gastric cancer-related, metastases-related and treatment-related candidate prognostic factors. Results: Seventeen patients received supportive care, 44 minor palliative surgery, 98 palliative gastrectomy in 16 cases associated to R+ hepatectomy, while 51 patients received both curative gastrectomy and hepatic resection/s (R0). Adjuvant chemotherapy was administered to 41 patients. Therapeutic approach was selected on the basis of stage of disease, patients’ general conditions and surgeon’s attitude toward the disease, without any pre-set common criteria, in absence of institutional protocols or guidelines. Surgical mortality was 4.6%, surgical morbidity 17.6%. Survival was independently influenced by the degree of hepatic involvement (p= 0.036) but therapeutic approach to the metastases was the principal prognostic variable (p<0.001): 1, 3, and 5 years survival rates were 48.3%, 11.8% and 7.1%, respectively, for patients submitted to curative surgery (R0), 16%, 4.3% and 2.1% after palliative (R+) gastrectomy, 6,8%, 0% and 0% after minor palliative surgery and 0%,0% and 0% with supportive care. Chemotherapy displayed a clear prognostic role (p< 0.001) with clear benefit for those receiving adjuvant treatment. Conclusions: Our data show that an aggressive multimodal approach offers the best survival chances, the best results being offered by the association of radical (R0) surgery and adjuvant chemotherapy. Upon these bases we conclude that this aggressive management must be pursued whenever possible.

Validation of the new AJCC TNM staging system for gastric cancer in a large cohort of patients (n = 2,155): focus on the T category. Eur J Surg Oncol 2011; 37:779-85. [PMID: 21726975 DOI: 10.1016/j.ejso.2011.06.001] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2011] [Revised: 05/30/2011] [Accepted: 06/13/2011] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND The prognostic value of T subclassification in patients with gastric carcinoma has been just implemented in the new AJCC TNM staging system, which has reclassified T2a and T2b into T2 and T3 tumors, respectively. The aim of the present study was to validate the prognostic significance of the new T categorization within the frame of the latest TNM staging system. METHODS We retrospectively reviewed the records of 686 T2/T3 patients among 2155 subjects who underwent radical resection for gastric carcinoma at six Italian centers from 1988 through 2006. RESULTS Upon multivariate analysis, the new T categories, extent of lymph node dissection (D) and patient's age were retained by the survival model as independent prognostic factors. In particular, the death risk for patients with T3 tumors was higher than that of patients with T2 tumors (HR: 1.42, P = 0.005). Among the 686 patients previously classified as having T2 tumors, patients with T2 and T3 disease were 270 (39.4%) and 416 (60.6%), respectively. After a median follow-up of 55 months, the 5-year overall survival rates were 67.3% and 52.3% for patients with T2 and T3 tumors, respectively (P < 0.001). The survival advantage for the T2 as compared to T3 category was maintained even when N0 and N+ patients were separately considered (P = 0.0154 and P < 0.001, respectively). CONCLUSIONS Our data confirm the prognostic difference between the newly proposed T2 and T3 categories, which should be implemented in the routine clinical practice to improve risk stratification of patients with gastric cancer.

EUS for the staging of gastric cancer: a meta-analysis. Gastrointest Endosc 2011; 73:1122-34. [PMID: 21444080 DOI: 10.1016/j.gie.2011.01.030] [Citation(s) in RCA: 82] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2010] [Accepted: 01/13/2011] [Indexed: 12/14/2022]
Abstract
BACKGROUND The role of EUS in the locoregional staging of gastric carcinoma is undefined. OBJECTIVE We aimed to comprehensively review and quantitatively summarize the available evidence on the staging performance of EUS. DESIGN We systematically searched the MEDLINE, Cochrane, CANCERLIT, and EMBASE databases for relevant studies published until July 2010. SETTING Formal meta-analysis of diagnostic accuracy parameters was performed by using a bivariate random-effects model. PATIENTS Fifty-four studies enrolling 5601 patients with gastric cancer undergoing disease staging with EUS were eligible for the meta-analysis. MAIN OUTCOME MEASUREMENTS EUS staging accuracy across eligible studies was measured by computing overall sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), and diagnostic odds ratio (DOR). RESULTS EUS can differentiate T1-2 from T3-4 gastric cancer with high accuracy, with overall sensitivity, specificity, PLR, NLR, and DOR of 0.86 (95% CI, 0.81-0.90), 0.91 (95% CI, 0.89-0.93), 9.8 (95% CI, 7.5-12.8), 0.15 (95% CI, 0.11-0.21), and 65 (95% CI, 41-105), respectively. In contrast, the diagnostic performance of EUS for lymph node status is less reliable, with overall sensitivity, specificity, PLR, NLR, and DOR of 0.69 (95% CI, 0.63-0.74), 0.84 (95% CI, 0.81-0.88), 4.4 (95% CI, 3.6-5.4), 0.37 (95% CI, 0.32-0.44), and 12 (95% CI, 9-16), respectively. Results regarding single T categories (including T1 substages) and Bayesian nomograms to calculate posttest probabilities for any target condition prevalence are also provided. LIMITATIONS Statistical heterogeneity was generally high; unfortunately, subgroup analysis did not identify a consistent source of the heterogeneity. CONCLUSIONS Our results support the use of EUS for the locoregional staging of gastric cancer, which can affect the therapeutic management of these patients. However, clinicians must be aware of the performance limits of this staging tool.

Abstract
BACKGROUND The aim of the present multicentre observational study was to evaluate potential changes in clinical and pathological features of patients with gastric cancer (GC) treated in a 15-year interval. METHODS A centralized prospective database including clinical, surgical, pathological and follow-up data from 2822 patients who had resection of a primary GC was analysed. The analysis focused on three periods: 1991-1995 (period 1), 1996-2000 (period 2) and 2001-2005 (period 3). Surgical procedure, pathological classification and follow-up were standardized among centres. RESULTS The number of resections decreased from 1024 in period 1 to 955 and 843 in periods 2 and 3 respectively. More advanced stages and a smaller number of intestinal-type tumours of the distal third were observed over time. Five-year survival rates after R0 resection (2320 patients) did not change over time (overall: 56·6 and 51·2 per cent in periods 1 and 3; disease-free: 66·8 and 61·1 per cent respectively). Decreases in survival in more recent years were related particularly to more advanced stage, distal tumours and tumours in women. Multivariable analysis showed a lower probability of overall and disease-free survival in the most recent interval: hazard ratio 1·22 (95 per cent confidence interval 1·06 to 1·40) and 1·29 (1·06 to 1·58) respectively compared with period 1. Recurrent tumours were more frequently peritoneal rather than locoregional. CONCLUSION Overall and disease-free survival rates after R0 resection of GC were unchanged over time.

Abstract
BACKGROUND This study was to assess the influence of perioperative blood transfusions on the prognosis of patients undergoing a potentially curative resection for gastric cancer and to investigate the interaction between transfusions and splenectomy. MATERIALS AND METHODS Between January 1990 and December 2005, 927 patients from 6 Italian tertiary referral centers underwent curative resections for gastric cancer. Clinical and pathologic variables were prospectively collected. The influence of perioperative blood transfusions on survival were evaluated by univariate and multivariate analysis. Moreover, the influence of splenectomy both in transfused and nontransfused patients undergoing total gastrectomy was also evaluated. RESULTS The overall 5-year survival was 54.6%. The 5-year survival rate in transfused patients (n = 327) was 50.6% compared with 56.6% in nontransfused patients (n = 600) (P = .094). In the subgroup of patients who underwent total gastrectomy with spleen preservation (n = 209), 5-year survival rate was 46% and 51.4% in transfused and nontransfused patients, respectively (P = .418); those who underwent total gastrectomy with splenectomy (n = 199) presented a 5-year survival rate of 45% in transfused group compared with 39.1% in nontransfused patients (P = .571). CONCLUSIONS Our study indicates a slightly, but not significantly, negative effect of allogeneic blood transfusion on prognosis of gastric cancer patients. In the subgroup of patients who underwent total gastrectomy, splenectomy seems to invert this mild effect, with a positive influence on overall survival.

Abstract
AIM This was a phase II study to assess the activity of a novel neoadjuvant regimen in locally-advanced breast cancer. PATIENTS AND METHODS Fifty patients with histological confirmation of locally advanced breast cancer received treatment with gemcitabine 1000 mg/m(2) (day 1) followed by gemcitabine 800 mg/m(2) plus docetaxel 75 mg/m(2) plus pegylated liposomal doxorubicin (PLD) 30 mg/m(2) (day 8) every 3 weeks for at least 4 cycles, plus a final 2 additional cycles. Tumour size was T1 (n=2), T2 (n=32), T3 (n=14), T4 (n=2). All 50 patients underwent surgery. RESULTS Clinical complete, partial and no response were observed in 13 (26%), 24 (48%) and 11 (22%) patients, respectively (overall response rate: 74%). The number of chemotherapy cycles was found to be an independent predictor of a pathologic complete response. CONCLUSION The combination of gemcitabine-docetaxel-PLD can yield high tumour response rates in patients with locally-advanced breast cancer who undergo a full treatment of 6 cycles.

Survivin gene levels in the peripheral blood of patients with gastric cancer independently predict survival. J Transl Med 2009; 7:111.

Abstract
BACKGROUND The detection of circulating tumor cells (CTC) is considered a promising tool for improving risk stratification in patients with solid tumors. We investigated on whether the expression of CTC related genes adds any prognostic power to the TNM staging system in patients with gastric carcinoma. METHODS Seventy patients with TNM stage I to IV gastric carcinoma were retrospectively enrolled. Peripheral blood samples were tested by means of quantitative real time PCR (qrtPCR) for the expression of four CTC related genes: carcinoembryonic antigen (CEA), cytokeratin-19 (CK19), vascular endothelial growth factor (VEGF) and Survivin (BIRC5). RESULTS Gene expression of Survivin, CK19, CEA and VEGF was higher than in normal controls in 98.6%, 97.1%, 42.9% and 38.6% of cases, respectively, suggesting a potential diagnostic value of both Survivin and CK19. At multivariable survival analysis, TNM staging and Survivin mRNA levels were retained as independent prognostic factors, demonstrating that Survivin expression in the peripheral blood adds prognostic information to the TNM system. In contrast with previously published data, the transcript abundance of CEA, CK19 and VEGF was not associated with patients' clinical outcome. CONCLUSIONS Gene expression levels of Survivin add significant prognostic value to the current TNM staging system. The validation of these findings in larger prospective and multicentric series might lead to the implementation of this biomarker in the routine clinical setting in order to optimize risk stratification and ultimately personalize the therapeutic management of these patients.

Abstract
BACKGROUND The incidence of gallstones and gallbladder sludge is known to be higher in patients after gastrectomy than in general population. This higher incidence is probably related to surgical dissection of the vagus nerve branches and the anatomical gastrointestinal reconstruction. Therefore, some surgeons perform routine concomitant cholecystectomy during standard surgery for gastric malignancies. However, not all the patients who are diagnosed to have cholelithiasis after gastric cancer surgery will develop symptoms or require additional surgical treatments and a standard laparoscopic cholecystectomy is feasible even in those patients who underwent previous gastric surgery. At the present, no randomized study has been published and the decision of gallbladder management is left to each surgeon preference. DESIGN The study is a randomized controlled investigation. The study will be performed in the General and Oncologic Surgery, Department of Oncology-Azienda Ospedaliero-Universitaria Careggi-Florence-Italy, a large teaching institution, with the participation of all surgeons who accept to be involved in, together with other Italian Surgical Centers, on behalf of the GIRCG (Italian Research Group for Gastric Cancer).The patients will be randomized into two groups: in the first group the patient will be submitted to prophylactic cholecystectomy during standard surgery for curable gastric cancer (subtotal or total gastrectomy), while in the second group he/she will be submitted to standard gastric surgery only.

Abstract
PURPOSE Resection line infiltration (RLI) after surgical treatment represents an unfavorable prognostic factor in advanced gastric cancer. We performed a retrospective analysis of 89 patients with resection line involvement who did not undergo reoperation. METHODS On behalf of the Italian Research Group for Gastric Cancer, we present the characteristics and outcome of 89 patients who were submitted to surgical resection for gastric cancer from 1988 to 2001 and did not undergo reoperation because of disease extension or associated pathologies. RESULTS RLI was significantly higher in patients with T4 tumors and diffuse histological type. Anastomotic leakages were observed in 4.8% of infiltrated esophageal resection margins, whereas 1.9% of infiltrated duodenal resection lines showed duodenal fistulas. Five-year overall survival of patients with RLI was 29%. Prognosis was not affected by RLI in early forms (100% 5-year survival); however, 5-year survival in T2 and T3 stages was significantly lower with respect to the same stages without residual tumor. The influence of RLI on prognosis was confirmed in N0 as well as in N1 and N2 patients. RLI also was an independent prognostic at multivariate analysis (odds ratio = 1.5; 95% confidence interval, 1.08-2.08; P = 0.0144). CONCLUSIONS RLI significantly affects long-term survival of advanced gastric cancer. The impact on prognosis is independent of lymph node involvement. Patients in good general condition for whom radical surgery is possible should be considered for reoperation.

Abstract
BACKGROUND This study was designed to evaluate the prognostic value of tumour stage T2 subcategorization (T2a and T2b) in patients with gastric carcinoma. METHODS Clinicopathological details of a prospective series of patients who had radical resection of gastric adenocarcinoma in a single institution were analysed. Univariable and multivariable survival analyses were performed with the log rank test and Cox's model respectively. RESULTS Of 373 evaluable patients, 49 (13.1 per cent) had a T2a and 143 (38.3 per cent) a T2b tumour. At a median follow-up of 35.5 months, the 5-year overall survival rate was 73 and 31.1 per cent for patients with T2a and T2b lesions respectively (P < 0.001). On multivariable analysis, T stage remained an independent prognostic factor. Compared with T1a, the mortality risk for patients with T1b (hazard ratio (HR) 1.00; P = 0.992) and T2a (HR 0.97; P = 0.916) tumours was similar; by contrast, the risk of death associated with T2b (HR 1.81; P = 0.031) and T3 (HR 1.89; P = 0.038) lesions was significantly greater than for T1a tumours. CONCLUSION Subclassification of T2 tumours should be undertaken routinely in order to stratify patients with gastric cancer more accurately in terms of their mortality risk.
