A rationale multidisciplinary approach for treatment of esophageal and gastroesophageal junction cancer: Accurate review of management and perspectives.

Cancer of the esophagus and of gastroesophageal junction can be cured, even if with lacking cure rate. Different approaches have been developed, mostly when carcinoma has loco-regional pattern. Multimodality therapy showed a survival rate superior than 10% if compared to a single approach. This is a systematic review, carried to assess the following matters: Which therapeutic opportunities are available? Who could benefit of them? Which adverse reactions could possibly verify? How can physicians definitely choose the proper strategy? Which is the role of surgery? We mean to give either General Practitioner or specialists clear and efficient updates about current treatment of this tumour, starting from physical examination. Four eminent guidelines were consulted for our study: Cancer Care Ontario's Program in Evidence-Based Care, NCCN, Belgian Health Care Knowledge Centre and Esmo.

Reliability and validity assessment of administrative databases in measuring the quality of rectal cancer management.

PURPOSE: Measurement and monitoring of the quality of care using a core set of quality measures are increasing in health service research. Although administrative databases include limited clinical data, they offer an attractive source for quality measurement. The purpose of this study, therefore, was to evaluate the completeness of different administrative data sources compared to a clinical survey in evaluating rectal cancer cases. METHODS: Between May 2012 and November 2014, a clinical survey was done on 498 Lombardy patients who had rectal cancer and underwent surgical resection. These collected data were compared with the information extracted from administrative sources including Hospital Discharge Dataset, drug database, daycare activity data, fee-exemption database, and regional screening program database. The agreement evaluation was performed using a set of 12 quality indicators. RESULTS: Patient complexity was a difficult indicator to measure for lack of clinical data. Preoperative staging was another suboptimal indicator due to the frequent missing administrative registration of tests performed. The agreement between the 2 data sources regarding chemoradiotherapy treatments was high. Screening detection, minimally invasive techniques, length of stay, and unpreventable readmissions were detected as reliable quality indicators. Postoperative morbidity could be a useful indicator but its agreement was lower, as expected. CONCLUSIONS: Healthcare administrative databases are large and real-time collected repositories of data useful in measuring quality in a healthcare system. Our investigation reveals that the reliability of indicators varies between them. Ideally, a combination of data from both sources could be used in order to improve usefulness of less reliable indicators.

Hereditary diffuse gastric cancer in two families: A case report.

Hereditary diffuse gastric cancer (HDGC) is associated with E-cadherin 1 (CDH1) germline mutations. In the present study, two unusual HDGC cases are described. Case 1 was a female with no family history of gastric cancer who developed Hodgkin's lymphoma at 19 years of age, and DGC at 32 years of age. Due to her young age (32 years), the patient was examined for CDH1 abnormalities and a deleterious mutation was identified. Her father and younger sister were identified to be carriers of the mutation. Case 2 was a 36-year-old female diagnosed with lobular breast cancer (LBC); her mother had LBC, and her grandmother had LBC and DGC. The molecular test was wild-type for breast cancer susceptibility genes 1 and 2; however, a large deletion in CDH1 was identified. At prophylactic gastrectomy, early DGC was identified. Early onset of DGC and LBC justifies testing for CDH1. A better knowledge of tumor natural history in carrier subjects is important to aid genetic counseling, in order to assess the surveillance time required prior to carrying out prophylactic surgery.

Open, laparoscopic, and robotic surgery for rectal cancer: medium-term comparative outcomes from a multicenter study.

PURPOSE: Several studies have demonstrated the oncologic equivalence of laparoscopic (LS) and open (OS) rectal cancer surgeries and have shown how challenging LS may become. Robotic surgery (RS) has emerged as a practical alternative, offering interesting advantages in comparison to both LS and OS. The aim of this study is to resolve the clinicopathologic outcome advantages of RS with respect to OS and LS techniques. METHODS: Patients with rectal cancer undergoing OS, RS, or LS were evaluated within the period from April 2009 to August 2011. The evaluations were carried out in 4 Italian hospitals. Perioperative clinicopathologic data, postoperative complications, and 3-year overall and disease-free survival (DFS) rates were analyzed. RESULTS: A total of 160 patients (94 male, 66 female) were included. A total of 105 patients underwent mini-invasive procedure (40 LS; 65 RS), whereas OS was performed in 55 patients. Anterior resection of rectal cancer was the most performed surgical procedure (139; 87%). Median operation time was significantly longer in the RS group (p<0.01). Regarding complication rates and quality of the surgical specimen evaluation, no statistical difference was found among the 3 groups. The shortest hospital stay (p<0.01) was obtained from the LS and RS groups. The median follow-up was 33 months without any significant difference in overall and DFS rates. CONCLUSIONS: Although RS for rectal cancer requires more time to be performed than LS and OS techniques, the analysis shows comparatively the feasibility and safety of RS in terms of perioperative clinicopathologic and medium-term outcomes.

The Impact of pelvimetry on anastomotic leakage in a consecutive series of open, laparoscopic and robotic low anterior resections with total mesorectal excision for rectal cancer. .

BACKGROUND/AIMS: Recently, pelvic anatomy has been taken into consideration and related to surgical outcome indicators after low anterior resection (LAR). Several pelvimetric parameters have been matched with conversion rate, postoperative complications and duration of surgery in laparoscopic series, and with the quality of specimen and pathologic outcomes in further open surgical series. METHODOLOGY: In 97 consecutive patients submitted to sphincter-saving LAR with total mesorectal excision (TME) five pelvic dimensions were measured by abdominal computed tomography scan: anteroposterior and transverse diameters in the pelvic inlet (IAP and ITRA), anteroposterior and transverse diameters in the pelvic outlet (OAP and OTRA), and the pelvic depth. The endpoint evaluated was anastomotic leakage (AL) rate. RESULTS: There were 51 open, 12 laparoscopic and 34 robotic LARs. The sum of IAP OAP and OTRA (Pelvic Index) significantly predicted AL showing that starting from the cut-point of 290 mm down to a PI of 278 mm the odds-ratio of having an AL increased from 2.63 (95% CI: 1.10,5.47) to 5.07 (95% CI: 1.35,8.02). CONCLUSIONS: The sum of the 3 pelvic dimensions which we termed "Pelvic Index" was associated to AL following sphinctersaving LAR. This may be considered in planning the surgical strategy for rectal cancer patients.

Resection of the primary pancreatic neuroendocrine tumor in patients with unresectable liver metastases: possible indications for a multimodal approach.

BACKGROUND: Pancreatic neuroendocrine tumors (PNETs) present in more than 50% of cases with liver metastases as the only systemic localization. Liver metastases are unresectable in 80% of cases at diagnosis. In the context of a metastatic disease, the benefit of primary tumor removal in terms of survival is controversial. METHODS: A single-center series of patients with PNETs presenting with synchronous unresectable hepatic metastases and treated within a framework of a multidisciplinary team was analyzed retrospectively to assess the prognostic factors and the potential benefit of primary tumor resection on long-term survival. RESULTS: At the time of diagnosis, 12 of 43 patients (28%) underwent primary tumor resection. After a median follow-up of 5 years (range, 0.6-14 years), 22 disease-related deaths were observed. The corresponding 5-year survival and median disease-specific duration of survival were 58% and 77 months, respectively. In the operated and nonoperated patients the 5-year disease-specific survival was 82% and 50%, respectively (P = .027). At multivariate analysis, patients with primary tumor removed had an improved survival compared with patients who did not (hazard ratio 0.18; 95% CI 0.05-0.66; P = .010). Other important factors associated with improved survival at multivariate analysis were lesser age, lesser Ki-67 index, and 25% less liver tumor burden. CONCLUSION: In the present series of patients with PNETs and unresectable liver metastases, resection of the primary tumor was associated with an improved survival. This observation suggests that resection of the primary tumor should be part of a global therapeutic strategy and its indication and timing should be discussed within a multidisciplinary team.

Factors predicting worse prognosis in patients affected by pT3 N0 colon cancer: long-term results of a monocentric series of 137 radically resected patients in a 5-year period.

BACKGROUND AND PURPOSE: For patients with Stage II colon cancer, the use of adjuvant chemotherapy remains controversial. The purpose of this study was to identify clinical and/or pathological findings related to a worse prognosis in this category of patients. PATIENTS AND METHODS: We retrospectively analyzed the data of consecutive patients, extracted by an institutional Tumour Registry, admitted to an affiliated University Hospital in Milan (European Institute of Oncology) for adenocarcinoma of the colon (all sites), between 2000 and 2005, and having a final pT3 N0 pathology staging after curative surgery. Adjuvant chemotherapy was decided as a result of a medical decision within a multidisciplinary Tumor Board. RESULTS: Data of 137 patients were obtained, with a median follow-up of 77 months (range 6-131). Patients who received chemotherapy were younger than patients who did not. Nine patients out of 137 (6.5 %) died as a consequence of colon cancer recurrence; four of them had received adjuvant chemotherapy. Only histological grade III and mucinous histotype were found to impact on cumulative incidence of colon-related events (p 0.03 and 0.02, respectively); no impact was found on cumulative incidence of colonic neoplasm recurrence-related deaths (p 0.74 and 0.74, respectively). Number of analyzed LNs (lymph nodes) emerged as a factor possibly affecting the cumulative incidence of colon-related events (p 0.09) as well as the cumulative incidence of colonic neoplasm recurrence-related deaths (p 0.10). The risk of events was inversely proportional to the number of dissected LNs, even over 20 up to about 25 LNs. Never-smokers exhibited a lower incidence of colon-related events, although the difference was not statistically significant (p 0.09). All other analyzed variables did not show any impact on survival rate, including age, gender, ASA score, BMI, site of colonic neoplasm, multifocality, perivascular invasion, and use of adjuvant chemotherapy. CONCLUSIONS: Histology grading G3 and mucinous histotype were predictors of worse outcome. Efforts to improve LN evaluation should result in clinically significant improvements in outcome, and also the quality of care for patients with radically resected stage II colon cancer.

Recurrence and prognostic factors in patients with aggressive fibromatosis. The role of radical surgery and its limitations.

BACKGROUND: Surgery is still the standard treatment for aggressive fibromatosis (AF); however, local control remains a significant problem and the impact of R0 surgery on cumulative recurrence (CR) is objective of contradictory reports. METHODS: This is a single-institution study of 62 consecutive patients affected by extra-abdominal and intra-abdominal AF who received macroscopically radical surgery within a time period of 15 years. RESULTS: Definitive pathology examination confirmed an R0 situation in 49 patients and an R1 in 13 patients. Five-year CR for patients who underwent R0 vs R1 surgery was 7.1% vs 46.4% (P = 0.04) and for limbs vs other localizations 33.3% vs 9.9% (P = 0.02) respectively. In 17 patients who had intraoperative frozen section (IFS) margin evaluation R0 surgery was more common (17 of 17 vs 32 of 45, P = 0.01) and CR lower (five-year CR 0% vs 19.1%, respectively, P = 0.04). However, in multivariate analysis only limb localization showed a negative impact on CR (HR: 1.708, 95% CI 1.03 to 2.84, P = 0.04). CONCLUSIONS: IFS evaluation could help the surgeon to achieve R0 surgery in AF. Non-surgical treatment, including watchful follow-up, could be indicated for patients with limb AF localization, because of their high risk of recurrence even after R0 surgery.

Surgical site infections following colorectal cancer surgery: a randomized prospective trial comparing common and advanced antimicrobial dressing containing ionic silver.

BACKGROUND: An antimicrobial dressing containing ionic silver was found effective in reducing surgical-site infection in a preliminary study of colorectal cancer elective surgery. We decided to test this finding in a randomized, double-blind trial. METHODS: Adults undergoing elective colorectal cancer surgery at two university-affiliated hospitals were randomly assigned to have the surgical incision dressed with Aquacel Ag Hydrofiber dressing or a common dressing. To blind the patient and the nursing and medical staff to the nature of the dressing used, scrub nurses covered Aquacel Ag Hydrofiber with a common wound dressing in the experimental arm, whereas a double common dressing was applied to patients of control group. The primary end-point of the study was the occurrence of any surgical-site infection within 30 days of surgery. RESULTS: A total of 112 patients (58 in the experimental arm and 54 in the control group) qualified for primary end-point analysis. The characteristics of the patient population and their surgical procedures were similar. The overall rate of surgical-site infection was lower in the experimental group (11.1% center 1, 17.5% center 2; overall 15.5%) than in controls (14.3% center 1, 24.2% center 2, overall 20.4%), but the observed difference was not statistically significant (P = 0.451), even with respect to surgical-site infection grade 1 (superficial) versus grades 2 and 3, or grade 1 and 2 versus grade 3. CONCLUSIONS: This randomized trial did not confirm a statistically significant superiority of Aquacel Ag Hydrofiber dressing in reducing surgical-site infection after elective colorectal cancer surgery. TRIAL REGISTRATION: Clinicaltrials.gov: NCT00981110.

Acceptability and side-effects of colonoscopy and sigmoidoscopy in a screening setting.

OBJECTIVE: Quantitative information on adverse reactions associated with colorectal cancer (CRC) screening tests is useful to estimate the balance between benefit and risk in different strategies. SETTING: Six Italian screening centres. METHODS: Thirty-day active follow-up (interview about side-effects and acceptability of the screening procedure and review of hospital admissions) among average-risk people undergoing flexible sigmoidoscopy (FS), total colonoscopy (TC), fecal immunochemical test (FIT) in a multicentre randomized trial of CRC screening. Multivariable logistic models were used to assess determinants of completion rate and self-reported pain. RESULTS: The attendance rate following the first invitation and mail reminder was 28.2% (1696/6018) in the FS and 23.0% (1382/6021) in the TC arm. Response rate to the 30-day follow-up questionnaire was 88.6% (1502/1696) among people undergoing FS, and 86.7% (1198/1382) among those undergoing TC. The proportion of people complaining of serious reactions following bowel preparation (odds ratio [OR], 5.17; 95% confidence interval [CI] 3.70-7.24) or reporting severe pain immediately after the exam (OR, 1.86; 95% CI 1.47-2.34) was higher for TC than for FS. The most common post-procedural complaints were abdominal distension and pain. People mentioning pain or bowel distension following preparation were more likely to report severe pain both after FS (OR, 2.13; 95% CI 1.52-2.97) and TC (OR: 2.03; 95% CI 1.41-2.90). The 30-day hospitalization rate was similar after FS, TC and FIT. CONCLUSIONS: Screenees reported higher pain levels after TC than FS. The proportion of people complaining of severe side effects after discharge was similar. Bowel preparation was poorly tolerated by people undergoing TC. Subjects' reactions to the bowel preparation was predictive of post-procedural discomfort. A commitment of at least 48 hours was required of people undergoing TC, compared with 3-4 for FS.

Once-only sigmoidoscopy in colorectal cancer screening: follow-up findings of the Italian Randomized Controlled Trial--SCORE.

BACKGROUND: A single flexible sigmoidoscopy at around the age of 60 years has been proposed as an effective strategy for colorectal cancer (CRC) screening. METHODS: We conducted a randomized controlled trial to evaluate the effect of flexible sigmoidoscopy screening on CRC incidence and mortality. A questionnaire to assess the eligibility and interest in screening was mailed to 236,568 men and women, aged 55-64 years, who were randomly selected from six trial centers in Italy. Of the 56,532 respondents, interested and eligible subjects were randomly assigned to the intervention group (invitation for flexible sigmoidoscopy; n = 17,148) or the control group (no further contact; n = 17,144), between June 14, 1995, and May 10, 1999. Flexible sigmoidoscopy was performed on 9911 subjects. Intention-to-treat and per-protocol analyses were performed to compare the CRC incidence and mortality rates in the intervention and control groups. Per-protocol analysis was adjusted for noncompliance. RESULTS: A total of 34,272 subjects (17,136 in each group) were included in the follow-up analysis. The median follow-up period was 10.5 years for incidence and 11.4 years for mortality; 251 subjects were diagnosed with CRC in the intervention group and 306 in the control group. Overall incidence rates in the intervention and control groups were 144.11 and 176.43, respectively, per 100,000 person-years. CRC-related death was noted in 65 subjects in the intervention group and 83 subjects in the control group. Mortality rates in the intervention and control groups were 34.66 and 44.45, respectively, per 100,000 person-years. In the intention-to-treat analysis, the rate of CRC incidence was statistically significantly reduced in the intervention group by 18% (rate ratio [RR] = 0.82, 95% confidence interval [CI] = 0.69 to 0.96), and the mortality rate was non-statistically significantly reduced by 22% (RR = 0.78; 95% CI = 0.56 to 1.08) compared with the control group. In the per-protocol analysis, both CRC incidence and mortality rates were statistically significantly reduced among the screened subjects; CRC incidence was reduced by 31% (RR = 0.69; 95% CI = 0.56 to 0.86) and mortality was reduced by 38% (RR = 0.62; 95% CI = 0.40 to 0.96) compared with the control group. CONCLUSION: A single flexible sigmoidoscopy screening between ages 55 and 64 years was associated with a substantial reduction of CRC incidence and mortality.

Assessing appropriateness for elective colorectal cancer surgery: clinical, oncological, and quality-of-life short-term outcomes employing different treatment approaches.

PURPOSE: In recent years, colorectal cancer surgery has benefitted from new techniques such as laparoscopy and robotic surgery. However, many treatment disparities exist among different centers for patients affected by the same kind of tumors. METHODS: Forty-five (41%) open (OCO) vs. 30 (28%) laparoscopic (LCO) vs. 34 (31%) robotic-assisted (RCO) colectomies and 34 (40%) open (ORR) vs. 52 (60%) robotic (ROR) rectal resections performed during a 15-month period, in elective setting, were compared. Patients presenting contraindications for minimally invasive procedures were excluded from the study, so that all the enrolled patients were suitable for either of the surgical procedures. RESULTS: Overall morbidity rates were similar among groups. Perioperative mortality was nil. No significant differences were noted as for total number of lymph nodes harvested between arms. Mean time (days) to first bowel movement to gas was 3.3 vs. 2.3 vs. 2.6 for OCO, LCO, and RCO, respectively (p < 0.001), and 3.3 vs. 2.0 for ORR and ROR, respectively (p = 0.003). Among several European Organization in Research and Treatment of Cancer QLQ-C30 functional scales considered only physical functioning was significantly better at 30 days for RCO vs. OCO (96.3 ± 10 RCO vs. 85.5 ± 12.6 OCO; p = 0.015). Robotic surgery was much more expensive in comparison to open as well as laparoscopic procedures. CONCLUSIONS: Laparoscopic and robotic surgeries for colorectal cancer present both the same advantages in comparison to open procedures in terms of faster recovery. However, our data do not seem to support the routine use of RCO as a cost-effective procedure.

Multicentric GISCoR Study "intensive clinical follow-up versus surgical radicalization after complete endoscopic polypectomy of a malignant adenoma" (SEC-GISCoR).

Colorectal cancer screening programs result in an early diagnosis of the disease. In 2007, 250 malignant polyps were identified in Lombardy, out of 1,329 screen-detected colorectal carcinomas. The Italian Group for Colorectal Cancer (GISCoR) promoted the multicentric study "Endoscopic Follow-up versus Surgical Radicalization of Malignant Polyps after Complete Endoscopic Polypectomy" (SEC-GISCoR). The protocol was a multicentric, prospective, observational, non-randomized study. It included patients diagnosed a colorectal malignant adenoma, after complete endoscopic removal. From November 2005 to September 2009, three participating centers enrolled 120 patients with malignant polyps after "complete" endoscopic polypectomy; malignant polyps were classified as "low risk" or "high risk". The study had two arms: "Intensive follow-up" (42 patients: 32 with low-risk and 10 with high-risk polyps) and "Surgical radicalization" (78 patients: 5 with low-risk and 73 with high-risk polyps). Data were collected using an online CRF. Overall, 37/120 polyps (30.8%) were low risk and 83/120 (69.2%) were high risk. 42 out of 120 patients (35%) were enrolled in the "clinical follow-up" arm, while 78/120 (65%) entered the surgery arm. In 15 cases, patients were not enrolled in the correct arm, according to the criteria agreed upon before starting the study. There still is a high incidence (11.5%) of pathological mismatches. No clinical event was reported in 2.9 years of follow-up. In conclusion, some differences emerged in the management of patients with malignant polyps among participating centers (p < 0.001), mismatches can be explained by high surgical risk or patient's choice. Only in 5 cases (4.2%), did data analysis not allow to exactly determine the reason for a choice different from protocol criteria. The availability of new risk factors and the evidence of pathological mismatches confirmed the need for future studies on this issue.

Aggressive treatment approach for cloacogenic carcinoma of the anorectum: report from a single cancer center.

BACKGROUND/AIMS: The prognosis of cloacogenic carcinoma of the anorectum has rarely been investigated, and its clinical behavior is supposed to be similar to common squamous anal cancers. During the last 10 years, chemoradiation treatment (CRT) has been considered the standard of care for anal cancer. METHODS: We retrospectively investigated the treatment of cloacogenic cancers treated within the framework of a multidisciplinary cancer center team during an 8-year period. The medical records of 7 patients affected by cloacogenic carcinoma were analyzed. Three patients presented distant metastases at the time of diagnosis. CRT using 5-fluorouracil + mitomycin or cisplatin was considered the gold standard for those cases amenable to cure. RESULTS: After a mean follow-up time of 33 months (range 9-100), disease recurrence or progression was observed in 6 patients, which caused death in 3 of them. Three- and 5-year actuarial overall survival rates were 71 and 48%, respectively. CONCLUSIONS: Our data seem to suggest that the cloacogenic origin could present prognostic relevance within the wide spectrum of anal cancers. This should be carefully considered when submitting patients to aggressive and prolonged treatments. However, this hypothesis needs to be confirmed by larger series of this disease.

Angiogenic cells, macroparticles and RNA transcripts in laparoscopic vs open surgery for colorectal cancer.

BACKGROUND: Angiogenesis is crucial for tissue repair and cancer progression. We investigated a panel of angiogenic cells, macroparticles and RNA transcripts before, during and after laparoscopic colectomy or open colectomy for colorectal cancer. RESULTS: Viable and apoptotic circulating endothelial cells were significantly increased after open but not after laparoscopic colectomy (p < 0.01). A significant decrease of circulating mRNA coding for VEGFR-C and D and PDGFR-ß was found after laparoscopic but not after open colectomy. METHODS: A total of 24 patients were enrolled. Viable and apoptotic circulating endothelial cells, progenitors and macroparticles were evaluated by flow cytometry. The number of copies of angiogenesis-related RNA transcripts we reevaluated by quantitative PCR. CONCLUSION: Open, but not laparoscopic colectomy, was associated with a significant post-operative increase in circulating endothelial cells, either apoptotic (likely due to surgery-related vascular damage) and viable (likely representing vascular remodeling). Circulating RNA copies coding for some angiogenic genes were significantly decreased after laparoscopic colectomy likely because of the removal of the tumor lesion. This decrease was not observed after open colectomy,were a more pronounced wave of angiogenesis related to wound healing was expected. These results indicate a relevant wave of angiogenesis-related cells and transcripts after open but not after laparoscopic colectomy.

Surgical outcome after docetaxel-based neoadjuvant chemotherapy in locally-advanced gastric cancer.

AIM: To investigate feasibility, morbidity and surgical mortality of a docetaxel-based chemotherapy regimen randomly administered before or after gastrectomy in patients suffering from locally-advanced resectable gastric cancer. METHODS: Patients suffering from locally-advanced (T3-4 any N M0 or any T N1-3 M0) gastric carcinoma, staged with endoscopic ultrasound, bone scan, computed tomography, and laparoscopy, were assigned to receive four 21 d/cycles of TCF (docetaxel 75 mg/m(2) day 1, cisplatin 75 mg/m(2) day 1, and fluorouracil 300 mg/m(2) per day for days 1-14), either before (Arm A) or after (Arm B) gastrectomy. Operative morbidity, overall mortality, and severe adverse events were compared by intention-to-treat analysis. RESULTS: From November 1999 to November 2005, 70 patients were treated. After preoperative TCF (Arm A), thirty-two (94%) resections were performed, 85% of which were R0. Pathological response was complete in 4 patients (11.7%), and partial in 18 (55%). No surgical mortality and 28.5% morbidity rate were observed, similar to those of immediate surgery arm (P = 0.86). Serious chemotherapy adverse events tended to be more frequent in arm B (23% vs 11%, P = 0.07), with a single death per arm. CONCLUSION: Surgery following docetaxel-based chemotherapy was safe and with similar morbidity to immediate surgery in patients with locally-advanced resectable gastric carcinoma.

Comparing different strategies for colorectal cancer screening in Italy: predictors of patients' participation.

OBJECTIVES: The objective of this study was to study predictors of patients' participation in colorectal cancer (CRC) screening. METHODS: Men and women, aged 55-64 years, were randomized to the following: (i) biennial fecal occult blood test (FOBT) delivered by mail (n=2,266); (ii) FOBT delivered by a general practitioner (GP)/screening facility (n=5,893); (iii) "once-only" sigmoidoscopy (FS) (n=3,650); (iv) FS followed by FOBT for screenees with negative FS (n=10,867); and (v) patient's choice between FS and FOBT (n=3,579). A stratified (by screening arm) random sample of attenders and nonattenders was contacted by trained interviewers 4 months after the initial invitation. Subjects giving their consent were administered a questionnaire (available online) investigating perceptions of individual CRC risk, attitudes toward prevention, adoption of health protective behaviors, and reasons for attendance/nonattendance. Adjusted prevalence odds ratios (ORs) were computed by multivariable logistic regression. RESULTS: The response rate was 71.9% (701 of 975) among nonattenders and 88.9% (773 of 870) among attenders. Adjusting for screening arm, center, gender, age, and education, participation was significantly higher among people who consulted their GP before undergoing screening (OR: 4.24; 95% confidence interval (CI): 3.11-5.78), who mentioned one first-degree relative with CRC (OR: 3.62; 95% CI: 2.02-6.49), who reported regular physical activity (OR: 1.85; 95% CI: 1.33-2.55), and who read the mailed information (letter only: OR: 1.85; 95% CI: 1.23-2.78; letter+leaflet: OR: 3.18; 95% CI: 2.12-4.76). People who considered screening to be ineffective (OR: 0.12; 95% CI: 0.08-0.19), those who considered it to be effective but reported even moderate levels of anxiety (OR: 0.32; 95% CI: 0.23-0.45), and those who mentioned previous knowledge of CRC screening tests were less likely to accept the invitation (OR: 0.49; 95% CI: 0.34-0.70). CONCLUSIONS: Adoption of health protective behaviors is associated with a higher attendance rate, whereas anxiety represents a strong barrier, even among people who deemed screening to be effective. Increasing the proportion of people who consult their GP when making a decision regarding screening might enhance participation.

Neoadjuvant chemotherapy followed by hepatectomy for primarily resectable colorectal cancer liver metastases.

BACKGROUND/AIMS: Hepatic resection in metastatic disease from colorectal cancer offers the best chance in selected cases for long-term survival. Neoadjuvant chemotherapy (NACT) has been advocated in some cases initially deemed irresectable with few reports of the efficacy of such a strategy and the influence of the response to chemotherapy on the outcome of radical hepatic resection. METHODOLOGY: Between December 1995 and May 2005, 88 patients with colorectal liver metastases underwent hepatic resection with curative intent. Twenty-five of these patients, (7 males, 18 females, mean age: 58+/-9 years; range: 40-75 years) deemed as resectable cases at the time of diagnosis were treated with neoadjuvant chemotherapy. A 7-year survival analysis was performed. Chemotherapy included mainly oxaliplatin or irinotecan containing regimens for a median of 6 courses. RESULTS: Fifteen patients (60%) had synchronous and 10 (40%) metachronous metastases. During preoperative chemotherapy tumor regression occurred in 8 cases (32%); stable disease (SD) in a further 10 patients (40%) and progressive disease (PD) developed in 7 cases (28%). The 5-year overall survival for NACT responders was 71% and only 15% for non-responders (p=0.026). CONCLUSIONS: The response to chemotherapy is likely to be a significant prognostic factor affecting overall survival after radical hepatic resection for colorectal metastases.

Desmoid tumors of the anterior abdominal wall: results from a monocentric surgical experience and review of the literature.

BACKGROUND: Desmoid tumor, also known as aggressive fibromatosis, is a rare soft tissue tumor. For those cases localized in the anterior abdominal wall, radical resection and reconstruction with a mesh is indicated. Because the rarity of the disease, randomized trials are lacking, but in reported retrospective series, it is clear that although it is considered a benign lesion, local recurrence is not uncommon. METHODS: We analyzed the records of 14 consecutive patients (3 men, 11 women, mean age 36 years, range 25-51 years) with desmoid tumor of the anterior abdominal wall treated at the European Institute of Oncology. The surgical strategy was the same in all cases: wide surgical excision and immediate plastic reconstruction with mesh after intraoperative confirmation by frozen sections of disease-free margins of >1 cm. We considered long-term outcomes by using the European Organization for the Research and Treatment of Cancer QLQ-C30 as an instrument to evaluate the overall quality of the treatment delivered to these patients. RESULTS: No immediate postoperative complication was registered, and no patient developed recurrence after a median follow-up period of 55 months. Two women experienced mesh bulging within 1 year after the operation. The long-term mean global health status registered was 97 out of 100. CONCLUSIONS: Radical resection aided by intraoperative margin evaluation via frozen sections followed by immediate mesh reconstruction is a safe procedure and can provide definitive cure without functional limitations for patients with desmoid tumors of the anterior abdominal wall.

Metachronous Colon Metastases from Gastric Adenocarcinoma: A Case Report.

The colon is a very rare metastatic localization. Here we report a case of colonic metastases from gastric adenocarcinoma whose clinical presentation was suggestive of a de novo adenocarcinoma of the ascending colon. The authors discuss that in the presence of a previous history of gastric cancer, immunohistochemical analysis on endoscopic biopsies may help in the definition of a differential diagnosis. Furthermore, this rare metastatic localization might suggest a poor prognosis and a more accurate diagnostic work-up.
