Emilia-Romagna Surgical Colorectal Cancer Audit (ESCA): a value-based healthcare retro-prospective study to measure and improve the quality of surgical care in colorectal cancer.

PURPOSE: Surgery is the main treatment for non-metastatic colorectal cancer. Despite huge improvements in perioperative care, colorectal surgery is still associated with a significant burden of postoperative complications and ultimately costs for healthcare organizations. Systematic clinical auditing activity has already proven to be effective in measuring and improving clinical outcomes, and for this reason, we decided to evaluate its impact in a large area of northern Italy. METHODS: The Emilia-Romagna Surgical Colorectal Audit (ESCA) is an observational, multicentric, retro-prospective study, carried out by 7 hospitals located in the Emilia-Romagna region. All consecutive patients undergoing surgery for colorectal cancer during a 54-month study period will be enrolled. Data regarding baseline conditions, preoperative diagnostic work-up, surgery and postoperative course will be collected in a dedicated case report form. Primary outcomes regard postoperative complications and mortality. Secondary outcomes include each center's adherence to the auditing (enrolment rate) and evaluation of the systematic feedback activity on key performance indicators for the entire perioperative process. CONCLUSION: This protocol describes the methodology of the Emilia-Romagna Surgical Colorectal Audit. The study will provide real-world clinical data essential for benchmarking and feedback activity, to positively impact outcomes and ultimately to improve the entire healthcare process of patients undergoing colorectal cancer surgery. CLINICAL TRIAL REGISTRATION: The study ESCA is registered on the clinicaltrials.gov platform (Identifier: NCT03982641).

Functional recovery and patient-reported outcomes after surgery.

This manuscript centers on what surgeons, patients, and hospital administrations want and need to know about the crucial role of functional recovery and patients' reported outcome measure, above all in the elderly population. From all angles, it is clear that elderly patients are unique and their cancer care should be individualized and approached in a multidisciplinary fashion. Evaluation of patient fitness to undergo surgery should be undertaken in the elective and emergent settings. If patients are deemed fit for treatment, they should be offered the appropriate treatment, regardless of their age. This includes proceeding with surgery and/or chemotherapy and utilizing minimally invasive techniques, when appropriate. In addition, quality of life should be a priority in the care of elderly patients and patient-reported outcomes should be assessed and reported.

Sulfasalazine in Prevention of Pouchitis After Proctocolectomy with Ileal Pouch-Anal Anastomosis for Ulcerative Colitis.

BACKGROUND: Pouchitis is the most frequent complication after ileal pouch-anal anastomosis for refractory ulcerative colitis. A non-standardized preventative treatment exists. Sulfasalazine has proved effective in acute pouchitis therapy. AIMS: The aim of this study was to retrospectively evaluate the effect of sulfasalazine in primary prophylaxis of pouchitis after proctocolectomy with ileal pouch-anal anastomosis. METHODS: Data files of patients who underwent total proctocolectomy with ileal pouch-anal anastomosis for refractory ulcerative colitis and/or dysplasia from January 2007 to December 2014, with a follow-up until August 2015, were analyzed. After closure of loop ileostomy, on a voluntary basis, patients received a primary prophylaxis of pouchitis with sulfasalazine (2000 mg per day) continually until acute pouchitis flare and/or drop out due to side effects. RESULTS: Follow-up data were available for 51 of the 55 surgical patients. Median follow-up time was 68 months (range 10-104). Thirty postoperative complications occurred in 25 patients. 45% of patients developed pouchitis. Sulfasalazine prophylaxis was administered in 39.2% of patients; 15% of the these developed pouchitis versus 64.5% (20/31) of the non-sulfasalazine patients (p < 0.001). Pouchitis-free survival curves were 90.55 months in sulfasalazine patients and 44.46 in non-sulfasalazine patients (log-rank test p = 0.001, Breslow p = 0.001). CONCLUSION: Sulfasalazine may be potentially administered in pouchitis prophylaxis after proctocolectomy with ileal pouch-anal anastomosis, but large prospectively controlled trials are needed.

Possible Gender-Related Modulation by the ROCK1 Gene in Colorectal Cancer Susceptibility.

AIM: In view of accumulating evidence supporting a pivotal role of the Rho/ROCK pathway in cancer, we investigated Rho-kinase polymorphisms as potential susceptibility factors in colorectal cancer (CRC) in a representative sample of the Italian population. METHODS: DNA obtained from the peripheral blood samples of 137 CRC patients and 141 healthy controls was genotyped for four ROCK1 (rs35996865; rs73963110; rs2127958; rs288980) and five ROCK2 (rs12692437; rs7563468; rs35768389; rs17463896; rs16857265) selected single nucleotide polymorphisms. RESULTS: None of the allelic variants of the nine selected markers was associated with the occurrence of CRC or with the development of regional lymph node metastasis. By contrast, the ROCK1 rs35996865 G variant allele was significantly more frequent in male patients (p = 0.028) than in the control group. CONCLUSION: This finding is, at present, the first that points to a possible gender-related modulation by the ROCK1 gene in CRC susceptibility.

Colorectal cancer susceptibility: apparent gender-related modulation by ABCB1 gene polymorphisms.

BACKGROUND: The ATP-binding cassette transporter B1 (ABCB1) gene codes for a membrane efflux pump localized in epithelial cells. Together with other Permeability-glycoproteins in the small and large intestine, its product represents a barrier against xenobiotics, bacterial toxins, drugs and other substances introduced with diet, including carcinogens. The aim of this investigation was to verify the possible contribution of ABCB1 single nucleotide polymorphisms (SNPs) to the genetic risk of colorectal cancer (CRC). RESULTS: DNA obtained from the peripheral blood of 98 CRC patients and 100 healthy controls was genotyped for the three selected SNPs: 1236C > T (rs1128503), 2677G > T/A (rs2032582), and 3435C > T (rs1045642). Molecular data were analyzed to asses allele and haplotype association with CRC. No evidence of an association between ABCB1 alleles and CRC occurrence as a whole was found. However, ABCB1 showed either association with carcinoma of the sigmoid colon, and appeared able to influence the sex ratio among CRC patients. These two effects seemed to act independently based on multivariate analysis. We showed that ABCB1 polymorphisms were able to influence CRC susceptibility related to tumor localization and patient gender. CONCLUSIONS: We suggest that sensitivity to undetermined risk factors could depend on the genetic background of ABCB1 locus, with a mechanism that also depends on patient gender.

A candidate gene study of one-carbon metabolism pathway genes and colorectal cancer risk.

The risk of colorectal cancer (CRC) may be influenced by aberrant DNA methylation and altered nucleotide synthesis and repair, possibly caused by impaired dietary folate intake as well as by polymorphic variants in one-carbon metabolism genes. A case-control study using seventy-one CRC patients and eighty unrelated healthy controls was carried out to assess the genetic association of fifteen SNP and one insertion in nine genes belonging to the folate pathway. Polymorphism selection was based on literature data, and included those which have a known or suspected functional impact on cancer and missense polymorphisms that are most likely to alter protein function. Genotyping was performed by real-time PCR and PCR followed by restriction analysis. The likelihood ratio statistic indicated that most of the polymorphisms were not associated with the risk of CRC. However, an increased risk of CRC was observed for two variant alleles of SNP mapping on the transcobalamin 2 gene (TCN2): C776G (rs1801198) and c.1026-394T>G (rs7286680). Considering the crucial biological function played by one-carbon metabolism genes, further investigations with larger cohorts of CRC patients are needed in order to confirm our preliminary results. These preliminary results indicate that TCN2 polymorphisms can be a susceptibility factor for CRC.

Frailty assessment can predict textbook outcomes in senior adults after minimally invasive colorectal cancer surgery.

AIM: Colorectal cancer (CRC) surgery can be associated with suboptimal outcomes in older patients. The aim was to identify the correlation between frailty and surgical variables with the achievement of Textbook Outcome (TO), a composite measure of the ideal postoperative course, by older patients with CRC. METHOD: All consecutive patients ≥70years who underwent elective CRC-surgery between January 2017 and November 2021 were analyzed from a prospective database. To obtain a TO, all the following must be achieved: 90-day survival, Clavien-Dindo (CD) < 3, no reintervention, no readmission, no discharge to rehabilitation facility, no changes in the living situation and length of stay (LOS) ≤5days/≤14days for colon and rectal surgery respectively. Frailty and surgical variables were related to the achievement of TO. RESULTS: Four-hundred-twenty-one consecutive patients had surgery (97.7% minimally invasive), 24.9% for rectal cancer, median age 80 years (range 70-92), median LOS of 4 days (range 1-96). Overall, 288/421 patients (68.4%) achieved a TO. CD 3-4 complications rate was 6.4%, 90-day mortality rate was 2.9%. At univariate analysis, frailty and surgical variables (ileostomy creation, p = 0.045) were related to. However, multivariate analysis showed that only frailty measures such as flemish Triage Risk Screening Tool≥2 (OR 1.97, 95%CI: 1.23-3.16; p = 0.005); Charlson Index>6 (OR 1.61, 95%CI: 1.03-2.51; p = 0.036) or Timed-Up-and-Go>20 s (OR 2.06, 95%CI: 1.01-4.19; p = 0.048) independently predicted an increased risk of not achieving a TO. CONCLUSION: The association between frailty and comprehensive surgical outcomes offers objective data for guiding family counseling, managing expectations and discussing the possible loss of independence with patients and caregivers.

Predicting Functional Recovery and Quality of Life in Older Patients Undergoing Colorectal Cancer Surgery: Real-World Data From the International GOSAFE Study.

PURPOSE: The GOSAFE study evaluates risk factors for failing to achieve good quality of life (QoL) and functional recovery (FR) in older patients undergoing surgery for colon and rectal cancer. METHODS: Patients age 70 years and older undergoing major elective colorectal surgery were prospectively enrolled. Frailty assessment was performed and outcomes, including QoL (EQ-5D-3L) recorded (3/6 months postoperatively). Postoperative FR was defined as a combination of Activity of Daily Living ≥5 + Timed Up & Go test <20 seconds + MiniCog >2. RESULTS: Prospective complete data were available for 625/646 consecutive patients (96.9%; 435 colon and 190 rectal cancer), 52.6% men, and median age was 79.0 years (IQR, 74.6-82.9 years). Surgery was minimally invasive in 73% of patients (321/435 colon; 135/190 rectum). At 3-6 months, 68.9%-70.3% patients experienced equal/better QoL (72.8%-72.9% colon, 60.1%-63.9% rectal cancer). At logistic regression analysis, preoperative Flemish Triage Risk Screening Tool ≥2 (3-month odds ratio [OR], 1.68; 95% CI, 1.04 to 2.73; P = .034, 6-month OR, 1.71; 95% CI, 1.06 to 2.75; P = .027) and postoperative complications (3-month OR, 2.03; 95% CI, 1.20 to 3.42; P = .008, 6-month OR, 2.56; 95% CI, 1.15 to 5.68; P = .02) are associated with decreased QoL after colectomy. Eastern Collaborative Oncology Group performance status (ECOG PS) ≥2 is a strong predictor of postoperative QoL decline in the rectal cancer subgroup (OR, 3.81; 95% CI, 1.45 to 9.92; P = .006). FR was reported by 254/323 (78.6%) patients with colon and 94/133 (70.6%) with rectal cancer. Charlson Age Comorbidity Index ≥7 (OR, 2.59; 95% CI, 1.26 to 5.32; P = .009), ECOG ≥2 (OR, 3.12; 95% CI, 1.36 to 7.20; P = .007 colon; OR, 4.61; 95% CI, 1.45 to 14.63; P = .009 rectal surgery), severe complications (OR, 17.33; 95% CI, 7.30 to 40.8; P < .001), fTRST ≥2 (OR, 2.71; 95% CI, 1.40 to 5.25; P = .003), and palliative surgery (OR, 4.11; 95% CI, 1.29 to 13.07; P = .017) are risk factors for not achieving FR. CONCLUSION: The majority of older patients experience good QoL and stay independent after colorectal cancer surgery. Predictors for failing to achieve these essential outcomes are now defined to guide patients' and families' preoperative counseling.

Effectiveness of sentinel lymph node intraoperative examination in 753 women with breast cancer: are we overtreating patients?

OBJECTIVE: The goal of our study was to evaluate the sensitivity and specificity of sentinel lymph node biopsy (SLNB) frozen section (FS) examinations to detect metastatic lymph nodes and also its potential role in avoiding unnecessary demolitive axillary surgery. BACKGROUND: SLNB is the standard of care in surgical oncology of the breast. Intraoperative evaluation of the SLN seems to achieve sufficient sensitivity for macrometastasis (Ma), leading to axillary lymph node dissection (ALND) only when strictly necessary. Is it equally as clear when to perform ALND if micrometastasis (Mi) or isolated tumor cells (ITCs) are detected? METHODS: All consecutive patients from January 2005 to September 2010 operated on for breast cancer were prospectively enrolled. All patients underwent an FS SLNB. The sensitivity and specificity of SLN FSs in detecting Ma, Mi, and ITCs was calculated. All patients with Ma or Mi at FS underwent ALND. For all patients who underwent ALND, the number of metastatic non-SLNs was recorded and correlated to the size of the SLN metastasis. RESULTS: A total of 753 patients were enrolled. FS examination had an overall 54% sensitivity and 100% specificity in detecting metastatic disease (Ma/Mi/ITCs). The sensitivity rises to 89% if only Mas were considered and to 64% if Mas and Mis were counted together. All patients with Mas or Mis detected at FS had a completion ALND during the same procedure (156/222). All patients with Mas detected at final pathology (16 false negatives, 2.6%) and 50 women with Mis or ITCs (119 false negatives, 20%) underwent a delayed ALND. When Mis or ITCs were detected in the SLN, only 8 of 73 (10.9%) and none of 4 (0%) patients, respectively, had at least 1 metastatic non-SLN after ALND. Two patients (2/460, 0.43%) who had negative SLNs showed local axillary recurrence. After a mean follow-up of 32 months, none of the 71 patients with Mis or ITCs who did not undergo a second operation showed local recurrence. CONCLUSIONS: SLNB FS is highly effective in detecting the subgroup of patients who may benefit from completion ALND during the same surgical procedure. The role of Mi/ITCs in the SLN(s) is still unclear, but our data lean toward a less aggressive surgical approach.

Immediate versus early (24-hours) urinary catheter removal after elective minimally invasive colonic resection: study protocol for a randomized, multicenter, non-inferiority trial.

BACKGROUND: Enhanced Recovery After Surgery (ERAS) represents the standard of care in colorectal surgery. Among ERAS items, early removal of urinary catheter (UC) is considered a key issue, though adherence to this specific item still varies among centers. UC placement allows for monitoring of post-operative urinary output but relates to an increased risk of urinary tract infection (UTI), reduced mobility, and patient's discomfort. Several studies investigated the role of early UC removal specifically looking at the rate of acute urinary retention (AUR) but most of them were retrospective, single-center, underpowered, cohort studies. The main purpose of this study is to compare the rate of AUR after immediate (at the end of the surgery) versus early (within 24 h from the completion of surgery) removal of UC in patients undergoing minimally invasive colonic resection (MICR). The secondary outcomes focus on goals that could be positively impacted by the immediate removal of the UC at the end of the surgery. In particular, the rate of UTIs, perception of pain, time-to-return of bowel and physical functions, postoperative complications, and length of hospital stay will be measured. METHODS: This is a prospective, randomized, controlled, two-arm, multi-center, study comparing the rate of AUR after immediate versus early removal of UC in patients undergoing MICR. The investigators hypothesize that immediate UC removal is non-inferior to 24-h UC removal in terms of AUR rate. Randomization is at the patient level and participants are randomized 1:1 to remove their UC either immediately or within 24 h from the completion of surgery. Those eligible for inclusion were patients undergoing any MICR with an anastomosis above the peritoneal reflection. Those patients who need to continue urinary output monitoring after the surgery will be excluded. The number of patients calculated to be enrolled in each group is 108 based on an expected AUR rate of 3% for the 24-h UC removal group and considering acceptable an AUR of 9% for the immediate UC removal group. DISCUSSION: The demonstration of a non-inferiority of immediate versus 24-h removal of UC would call into question the usefulness of urinary drainage in the setting of MICR. TRIAL REGISTRATION: ClinicalTrials.gov NCT05249192. Prospectively registered on February 21, 2022.

Quality of Life in Older Adults After Major Cancer Surgery: The GOSAFE International Study.

BACKGROUND: Accurate quality of life (QoL) data and functional results after cancer surgery are lacking for older patients. The international, multicenter Geriatric Oncology Surgical Assessment and Functional rEcovery after Surgery (GOSAFE) Study compares QoL before and after surgery and identifies predictors of decline in QoL. METHODS: GOSAFE prospectively collected data before and after major elective cancer surgery on older adults (≥70 years). Frailty assessment was performed and postoperative outcomes recorded (30, 90, and 180 days postoperatively) together with QoL data by means of the three-level version of the EuroQol five-dimensional questionnaire (EQ-5D-3L), including 2 components: an index (range = 0-1) generated by 5 domains (mobility, self-care, ability to perform the usual activities, pain or discomfort, anxiety or depression) and a visual analog scale. RESULTS: Data from 26 centers were collected (February 2017-March 2019). Complete data were available for 942/1005 consecutive patients (94.0%): 492 male (52.2%), median age 78 years (range = 70-95 years), and primary tumor was colorectal in 67.8%. A total 61.2% of all surgeries were via a minimally invasive approach. The 30-, 90-, and 180-day mortality was 3.7%, 6.3%, and 9%, respectively. At 30 and 180 days, postoperative morbidity was 39.2% and 52.4%, respectively, and Clavien-Dindo III-IV complications were 13.5% and 18.7%, respectively. The mean EQ-5D-3L index was similar before vs 3 months but improved at 6 months (0.79 vs 0.82; P < .001). Domains showing improvement were pain and anxiety or depression. A Flemish Triage Risk Screening Tool score greater than or equal to 2 (odds ratio [OR] = 1.58, 95% confidence interval [CI] = 1.13 to 2.21, P = .007), palliative surgery (OR = 2.14, 95% CI = 1.01 to 4.52, P = .046), postoperative complications (OR = 1.95, 95% CI = 1.19 to 3.18, P = .007) correlated with worsening QoL. CONCLUSIONS: GOSAFE shows that older adults' preoperative QoL is preserved 3 months after cancer surgery, independent of their age. Frailty screening tools, patient-reported outcomes, and goals-of-care discussions can guide decisions to pursue surgery and direct patients' expectations.

Fecal detection of Mycobacterium avium paratuberculosis using the IS900 DNA sequence in Crohn's disease and ulcerative colitis patients and healthy subjects.

BACKGROUND AND AIM: Despite the increasing evidence of MAP/DNA isolation in Crohn's disease (CD), its potential pathogenetic role remains unclear. To further clarify the possible relationship between MAP and CD, we investigated the presence of IS900 DNA fragment in feces from Crohn's disease and ulcerative colitis (UC) patients and from healthy controls (HC). METHODS: Stool samples were collected from 31 CD, 20 UC, and 23 HC and stored at -20°C in 200-mg aliquots. DNA was extracted. MAP presence was detected with a specific PCR amplifying a 409-bp fragment from IS900. The specificity of PCR for IS900 was confirmed sequencing three positive products. Statistical analysis was performed using the Chi-square test. RESULTS: Twenty-one of 31 CD (68%), 13 of 20 UC (65%) and 11 of 23 HC (48%) were MAP-positive (CD vs. HC: p = ns; UC vs. HC: p = ns). With the limits of a small sample size, the IS900-positive percentage in CD and UC was higher than HC, although the difference was not statistically significant. CONCLUSIONS: The possibility to track the MAP presence in human feces represents a new approach to the "MAP hypothesis". Detection of MAP DNA in feces is very common, reaching very high prevalence both in CD and in UC and even in HC. Our findings seem consistent with a high prevalence of MAP asymptomatic infection among the general population and so the possible involvement of MAP in CD pathogenesis could be linked to a specific immune defective response.

Prediction of functional loss in emergency surgery is possible with a simple frailty screening tool.

BACKGROUND: Senior adults fear postoperative loss of independence the most, and this might represent an additional burden for families and society. The number of geriatric patients admitted to the emergency room requiring an urgent surgical treatment is rising, and the presence of frailty is the main risk factor for postoperative morbidity and functional decline. Frailty assessment in the busy emergency setting is challenging. The aim of this study is to verify the effectiveness of a very simple five-item frailty screening tool, the Flemish version of the Triage Risk Screening Tool (fTRST), in predicting functional loss after emergency surgery among senior adults who were found to be independent before surgery. METHODS: All consecutive individuals aged 70 years and older who were independent (activity of daily living (ADL) score ≥5) and were admitted to the emergency surgery unit with an urgent need for abdominal surgery between December 2015 and May 2016 were prospectively included in the study. On admission, individuals were screened using the fTRST and additional metrics such as the age-adjusted Charlson Comorbidity Index (CACI) and the ASA score. Thirty- and 90-day complications and postoperative decline in the ADL score where recorded. Regression analysis was performed to identify preoperative predictors of functional loss. RESULTS: Seventy-eight patients entered the study. Thirty-day mortality rate was 12.8% (10/78), and the 90-day overall mortality was 15.4% (12/78). One in every four patients (17/68) experienced a significant functional loss at 30-day follow-up. At 90-day follow-up, only 3/17 patients recovered, 2 patients died, and 12 remained permanently dependent. On the regression analysis, a statistically significant correlation with functional loss was found for fTRST, CACI, and age≥85 years old both at 30 and 90 days after surgery. fTRST≥2 showed the highest effectiveness in predicting functional loss at 90 days with AUC 72 and OR 6.93 (95% CI 1.71-28.05). The institutionalization rate with the need to discharge patients to a healthcare facility was 7.6% (5/66); all of them had a fTRST≥2. CONCLUSION: fTRST is an easy and effective tool to predict the risk of a postoperative functional decline and nursing home admission in the emergency setting.

Reduced duration of stay after elective colorectal surgery during the peak phase of COVID-19 pandemic: A positive effect of infection risk awareness?

BACKGROUND: While elective surgery was shut down in most settings during the 2019 novel coronavirus pandemic, some referral centers were designated as surgery hubs. We sought to investigate how the pandemic scenario impacted the quality of a long-established enhanced recovery protocol colorectal surgery program in 2 referral centers, designated as colorectal surgery hubs, located in the epicentral Italian regions hardest hit by the pandemic. METHODS: We compared short-term outcomes of patients undergoing major colorectal surgery with a long-established enhanced recovery protocol during the coronavirus disease 2019 outbreak occurred in 2020 (group A) with the correspondent timeframe of 2019 (group B). Primary outcomes were morbidity and mortality, duration of stay, and readmission rate. RESULTS: One hundred and thirty-six patients underwent major colorectal surgery in group A and 173 in group B. Postoperative complications and readmission rate were comparable between the 2 groups. Oncologic case-log was predominant in group A compared with group B (73.5 vs 61%; P = .01). A significantly shorter overall duration of stay was found in group A (P < .001). Uncomplicated patients of group A had a shorter duration of stay when compared with uncomplicated patients of group B (P = .008). CONCLUSION: Under special precautionary measures, major colorectal surgery can be undertaken on elective basis even during coronavirus disease 2019 pandemic with reasonable results. A reduction of duration of stay within a long-established enhanced recovery protocol colorectal surgery program was observed during the coronavirus disease 2019 pandemic occurred in 2020 in comparison with the correspondent timeframe of the previous year without compromising short-term outcomes. The pandemic uncovered the positive impact of patients' commitment to reducing duration of stay as the empowered risk awareness likely promoted their compliance to the enhanced recovery protocol.

Urgent and emergency surgery for secondary peritonitis during the COVID-19 outbreak: an unseen burden of a healthcare crisis.

The COVID-19 pandemic has raised concerns about the negative impact of the fear of contagion on people's willingness to seek medical care and the subsequent effects on patients' prognosis. To date, not much is known about the outcomes of acute surgical diseases in this scenario. The aim of this multicenter observational study is to explore the effects of COVID-19 outbreak on the outcomes of patients who underwent surgery for peritonitis. Patients undergoing surgery for secondary peritonitis during the first COVID-19 surge in Italy (March 23-May 4, 2020-COVID period group) were compared with patients who underwent surgery during the same time interval of year 2019 (no-COVID period group). The primary endpoint was the development of postoperative complications. Logistic regression analysis was conducted to identify predictors of complications. Of the 332 patients studied, 149 were in the COVID period group and 183 were in the no-COVID period group. Patients in the COVID period group had an increased frequency of late presentations to the emergency departments (43% vs. 31.1%; P = 0.026) and a higher rate of postoperative complications (35.6% vs. 18%; P < 0.001). The same results were found in the subset analysis of patients with severe peritonitis at surgical exploration. The ASA score, severity of peritonitis, qSOFA score, diagnosis other than appendicitis, and COVID period resulted independent predictors of complications. During the COVID-19 pandemic patients with peritonitis had a higher rate of complicated postoperative courses, weighing on hospital costs and assistance efforts already pressured by the ongoing sanitary crisis.

Nipple discharge: is its significance as a risk factor for breast cancer fully understood? Observational study including 915 consecutive patients who underwent selective duct excision.

Nipple discharge (ND) is a common symptom seen in breast cancer clinics. The primary aim of this study was to identify preoperative risk factors for breast cancer in patients with pathologic ND. The secondary aim was to assess the clinical and pathological effectiveness of physical examination, galactography, cytological examination of the discharge, selective duct excision and ductoscopy. All patients operated on between 1975 and 2008 who presented with ND as their only symptom was analyzed. Discharge's characteristics, cytological data and galactography reports were recorded. The relationship between each individual finding and the risk of breast cancer was calculated. For each diagnostic tool, the sensitivity, specificity and complication rates were calculated and compared. Nine-hundred-fifteen patients underwent selective duct excision. Two-hundred-nineteen patients (23.9%) were found to be affected by carcinoma. In 100/330 (30.3%) patients with bloody discharge and in 42/239 (17.6%) patients with serous secretion cancer was detected (P = 0.004, P = 0.013, respectively). Patients with sero-sanguinous or coloured discharge had the same risk of cancer as the population analyzed (23.9%, P = NS). Galactographic finding of irregular stenosis seemed to be associated with a higher risk of cancer (P = 0.0001). Cytological findings C5 and C4 were associated with cancer (P = 0.001). Selective duct excision showed highest sensitivity and specificity. In conclusion, the well established role of bloody secretion is confirmed. The supposed benign aetiology of serous, coloured or sero-sanguinous discharge is questionable. The high specificity of the cytological exam justifies routine examination of the ND. Selective duct excision can be considered as the diagnostic gold-standard.

Clinically-staged T3N0 rectal cancer: is preoperative chemoradiotherapy the optimal treatment?

BACKGROUND: Preoperative chemoradiotherapy has been widely adopted as the standard of care for stage II-III rectal cancers. However, patients with T3N0 lesions had been shown to have a better prognosis than other categories of locally advanced tumor. Thus, neoadjuvant chemoradiation is likely to be overtreatment in this subgroup of patients. Nevertheless, the low accuracy rate of preoperative staging techniques for detection of node-negative tumors does not allow to check this hypothesis. We analyzed a group of patients with cT3N0 low rectal cancer who underwent neoadjuvant chemoradiotherapy with the purpose of evaluating the incidence of metastatic nodes in the resected specimens. METHODS: Between January 2002 and February 2008, 100 patients with low rectal cancer underwent clinical staging by means of endorectal ultrasound, computed tomography, positron emission tomography, and magnetic resonance imaging. All patients received preoperative 5-fluorouracil-based chemoradiotherapy and surgical resection with curative aim. RESULTS: Of 100 patients with locally advanced rectal cancer, 32 were clinically staged as T3N0M0. Pathological analysis showed the presence of lymph node metastases in nine patients (28%) (node-positive group). In the remaining 23 cases, clinical N stage was confirmed at pathology (node-negative group). Node-positive and node-negative groups differ only in the number of ypT3 tumors (P < .01). CONCLUSIONS: Our results indicate that immediate surgery for patients with cT3N0 rectal cancer represents an undertreatment risk in at least 28% of cases, making necessary the use of postoperative chemoradiotherapy. Preoperative chemoradiotherapy should be the therapy of choice on the grounds of the principle that overtreatment is less hazardous than undertreatment for cT3N0 rectal cancers.

A preliminary audit experience of surgery for rectal cancer after neoadjuvant chemoradiation therapy.

AIMS AND BACKGROUND: A surgical audit is a systematic critical analysis of surgical performance, with the goal to improve the quality of patient care. Rectal cancer surgery is one of the most delicate procedures in the field of surgical oncology, with significant variations in terms of complications from center to center. Neoadjuvant chemoradiation therapy leads to a significant reduction in local recurrences in patients with locally advanced lower and medium rectal cancer. The aim of the study was to evaluate the influence of neoadjuvant chemoradiation therapy on postoperative morbidity and mortality in patients with rectal cancer. METHODS AND STUDY DESIGN: From January 1, 2003, to December 31, 2007, patients who underwent elective surgical resection for lower and medium rectal cancer in our Surgical Unit were prospectively analyzed. Patients (n=42) were divided into two groups: (1) those treated with neoadjuvant chemotherapy and consequent surgical resection (19/42); (2) those treated with primary surgical treatment (23/42). P-POSSUM (Portsmouth Physiologic and Operative Severity Score for the Enumeration of Mortality and Morbidity) and CR-POSSUM (ColoRectal-POSSUM) scores were calculated for each patient group. Thirty-day mortality and morbidity rates were prospectively collected in a comprehensive data base. Data were evaluated by comparing the predictions of the two scoring systems in both study groups with clinically observed mortality and morbidity rates. RESULTS: In group 1, no death was registered (0/19). The P-POSSUM and CR-POSSUM expected mortality was 2.43% and 4.52%, respectively (P > 0.05). In group 2, a single death was documented (1/23, 4.35%). The P-POSSUM and CR-POSSUM expected mortality was 2.1% and 4.94%, respectively. The postoperative complications rate for group 1 was 10.52% (2/19) compared to 34.88% as expected from the P-POSSUM score (P < 0.05). In group 2, a postoperative complication rate of 39.13% (9/23) was observed compared to 34.26% as expected from the P-POSSUM score (P > 0.05). CONCLUSIONS: No significant influence on morbidity or mortality was detected in patients who underwent neoadjuvant radio-chemotherapy.

Functional and Short-term Outcomes in Elective Laparoscopic Colectomy for Symptomatic Diverticular Disease With Either Low Ligation or Inferior Mesenteric Artery Preservation: A Randomized Trial.

BACKGROUND: The current treatment of symptomatic diverticular disease is left colectomy/sigmoidectomy with low ligation of the inferior mesenteric artery versus the inferior mesenteric artery preservation. Up to now, there is no strong evidence in favor of one of the 2 strategies. The aim of this study is to compare the bowel-specific quality of life and functional outcomes between these 2. METHODS: Between June 2015 and February 2019, patients were randomly assigned to inferior mesenteric artery low ligation or inferior mesenteric artery preservation during elective laparoscopic sigmoidectomy for diverticular disease. Gastrointestinal, genitourinary functions and surgical outcomes were compared postoperatively between groups. RESULTS: One-hundred sixty-eight patients were randomized providing 2 homogenous groups. Gastrointestinal and genitourinary functions were not significantly different between groups after 1 and 6 months postoperative. In both groups, the function was restored to the preoperative level 6 months after surgery. There was no statistically significant difference in terms of conversion rate, blood loss, length of surgery, between groups. There was no difference in the overall complication rate and the anastomotic leak rate among groups. CONCLUSIONS: Inferior mesenteric artery low ligation or inferior mesenteric artery preservation during elective laparoscopic sigmoidectomy for a diverticular disease can be considered equivalent in affecting the postoperative bowel-related quality of life, genitourinary function, and surgical outcomes.

Long-Term Survival and Risk of Institutionalization in Onco-Geriatric Surgical Patients: Long-Term Results of the PREOP Study.

OBJECTIVES: To evaluate long-term survival and institutionalization in onco-geriatric surgical patients, and to analyze the association between these outcomes and a preoperative risk score. DESIGN: Prospective cohort study with long-term follow-up. SETTING: International and multicenter locations. PARTICIPANTS: Patients aged 70 years or older undergoing elective surgery for a malignant solid tumor at five centers (n = 229). MEASUREMENTS: We assessed long-term survival and institutionalization using the Preoperative Risk Estimation for Onco-geriatric Patients (PREOP) score, developed to predict the 30-day risk of major complications. The PREOP score collected data about sex, type of surgery, and the American Society for Anesthesiologists classification, as well as the Timed Up & Go test and the Nutritional Risk Screening results. An overall score higher than 8 was considered abnormal. RESULTS: We included 149 women and 80 men (median age = 76 y; interquartile range = 8). Survival at 1, 2, and 5 years postoperatively was 84%, 77%, and 56%, respectively. Moreover, survival at 1 year was worse for patients with a PREOP risk score higher than 8 (70%) compared with 8 or lower (91%). Of those alive at 1 year, 43 (26%) were institutionalized, and by 2 years, almost half of the entire cohort (46%) were institutionalized or had died. A PREOP risk score higher than 8 was associated with increased mortality (hazard ratio = 2.6; 95% confidence interval [CI] = 1.7-4.0), irrespective of stage and age, but not with being institutionalized (odds ratios = 1 y, 1.6 [95% CI = .7-3.8]; 2 y, 2.2 [95% CI = .9-5.5]). CONCLUSION: A high PREOP score is associated with mortality but not with remaining independent. Despite acceptable survival rates, physical function may deteriorate after surgery. It is imperative to discuss treatment goals and expectations preoperatively to determine if they are feasible. Using the PREOP risk score can provide an objective measure on which to base decisions.
