[The integrated care pathway for non melanoma skin cancer: the Istituto Dermopatico dell'Immacolata - IRCCS experience in Rome.] / Il percorso diagnostico-terapeutico e assistenziale nella gestione del paziente affetto da tumore cutaneo non melanocitario: l'esperienza dell'IDI - IRCCS di Roma.

The incidence of non-melanoma skin cancers (NMSC) is increasing worldwide and these skin cancers have become an important health issue. An integrated care pathway (ICP) is a multidisciplinary outline of anticipated care, placed in an appropriate timeframe, to help a patient with a specific condition. The aim of this paper is to define the ICP for patients affected by NMSC referring to the Istituto Dermopatico dell'Immacolata - IRCCS of Rome and Villa Paola, Italy. This ICP is multidisciplinary and included various specialists like dermatologist, oncologist, general surgeon, plastic surgeon, anatomopathologist, molecular biologist and epidemiologist. This ICP is based on the most recent acquisitions in the literature, referring in particular to the national (EADO and SIDEMAST) and international guidelines (EDF and NCCN). We firstly valued the current practice for patients affected by NMSC referring to our Institute to define the multidisciplinary process map. This process delineated the activities and the responsibilities performed during delivery of care to the patients and the potential problem areas or opportunities for improvements. Subsequently, we defined the final ICP process. This ICP of NMSC represents an innovative strategy to provide high quality healthcare. This allows to ensure all the necessary procedures for the patient, optimizing the "continuum" of care and the use of health services, and improving the organization of the Institute regarding an important health issue.

Reconstruction After Distal Gastrectomy for Gastric Cancer: Billroth 2 or Roux-En-Y Procedure?

BACKGROUND/AIM: Distal gastrectomy (DG) represents the only curative treatment for most mid-lower gastric cancers (GCs). As of 2017, however, no reconstructive modality to conduct after DG has gained unanimous consensus. Additionally, most authors have investigated Billroth 1 and Roux-en-Y (RY) rather than Billroth 2 (B2) reconstruction. We analyzed B2 and RY gastrojejunostomy to identify the preferable technique and augment the available information on B2 restoration. PATIENTS AND METHODS: We retrospectively selected 132 GC patients who were consecutively submitted to DG at our institution between April 2005 and February 2016. B2 and RY anastomosis were accomplished as methods of reconstruction (respectively 36 and 96 cases). We compared these techniques in terms of clinicopathological, surgical, postoperative and oncologic outcomes. RESULTS: Compared to RY gastrojejunostomy, B2 reconstruction was significantly associated with a greater mean number of harvested lymph nodes (26.03 vs. 21.65, p=0.045) but also with a longer hospital stay (22.8 vs. 15.7 days) (p=0.022) and higher readmission rate (28.57% vs. 3.1%, p<0.0001). On multivariate analysis, reconstruction method was the most significant independent prognostic factor for hospital readmission. CONCLUSION: In light of our results, we propose that B2 gastrojejunostomy deserves more study in order to better identify the best post-DG anastomosis.

Right Colectomy for Cancer: A Matched Comparison of Three Different Surgical Approaches.

PURPOSE: The standard approach to right colon cancer resection is still a matter of debate and includes laparoscopy, open midline incision, or open transverse incision. We aimed this study to compare the short- and long-term results of laparoscopic right-colectomy with those provided by the open approaches. METHODS: Of the 176 patients who underwent right-colectomy at our Department for nonmetastatic colon cancer, 40 patients treated by laparoscopy, 40 treated by transverse incisions, and 40 treated by midline incisions were selected and matched using the propensity score method. Short-term results included: operating time, morbidity rate, number of lymph-nodes harvested (LNH), patients' recovery features, and costs. Long-term results included: disease-specific survivals and the rate of incisional hernias. The sub-groups were compared using t-test and Chi-square tests, whereas the Kaplan-Meier method was used to assess survivals. RESULTS: Laparoscopies were the longer procedures, providing similar morbidity rates and LNH in comparison with the open approaches. Laparoscopy provided a faster return to oral intake and a shorter use of analgesics comparing with the midline approach; however, it showed only a minor consumption of analgesics in comparison with transverse laparotomy. There were no differences in the hospital stay and the long-term results were comparable between sub-groups. Costs analysis documented minor but not significant surgical expenses for the transverse approach. CONCLUSIONS: Laparoscopy was documented safe, with similar morbidity rates and long-term results comparing with open surgery. Laparoscopy provided better functional short-term results comparing with the midline approach, but only small differences with respect to the transverse incision approach.

Being positive despite illness: The contribution of positivity to the quality of life of cancer patients.

OBJECTIVE: The purpose of this study was to examine the longitudinal relationship between Positivity (POS), defined as a stable disposition to view at experience under a positive outlook, and physical and psychological functioning in a sample of cancer patients immediately after diagnosis and one year later. METHODS: A total of 110 patients (40% males) with pulmonary, colorectal and breast cancer, aged 30-75 (M age = 59.62; SD = 10.33), have been prospectively enrolled between 2012 and 2013, at the S. Andrea Hospital in Rome. All patients were previously aware of their diagnosis. A follow-up one year after diagnosis was conducted. We used structural equation modeling in order to analyse the specific effects of POS on functioning impairment from diagnosis to follow up. RESULTS: POS was associated with less functioning impairment both at diagnosis and follow-up assessments. Furthermore, POS level at diagnosis continued to be associated with less functioning impairment one year later, after controlling for its stability. CONCLUSIONS: Patients with higher level of POS tended to report less symptoms associated with negative affect such as anxiety and despondency and to preserve their habitual relationships and social roles. POS may act as a basic disposition that sustains patients' efforts to deal efficaciously with severe illness, by complying with medical treatment and using cognitive strategies that enable individuals to cope with concurrent and prospective challenges of illness.

Early onset pancreatic cancer: risk factors, presentation and outcome.

BACKGROUND: About 10% of pancreatic cancer patients are aged ≤50 at diagnosis and defined as Early Onset Pancreatic Cancer (EOPC). There is limited information regarding risk factors for EOPC occurrence and their outcome. AIM: To investigate risk factors, presentation features and outcome of EOPC patients. METHODS: Consecutive, histologically confirmed, pancreatic cancer patients enrolled. Data regarding environmental and genetic risk factors, clinical and pathological information, treatment and survival were recorded. EOPC patients (aged ≤50 at diagnosis) were compared to older subjects. RESULTS: Twenty-five of 293 patients (8.5%) had EOPC. There was no difference regarding sex distribution, medical conditions and alcohol intake between EOPC and older subjects. EOPC patients were more frequently current smokers (56% vs 28% p = 0.001) and started smoking at a significantly lower mean age (19.8 years, 95%CI 16.7-22.9) as compared to older patients (26.1, 95%CI 24.2-28) (p = 0.001). Current smoking (OR 7.5; 95%CI 1.8-30; p = 0.004) and age at smoking initiation (OR 0.8 for every increasing year; 95%CI 0.7-0.9; p = 0.01) were significant and independent risk factors for diagnosis of EOPC. There were no differences regarding genetic syndromes and pancreatic cancer family history. EOCP presented less frequently with jaundice (16% vs 44%, p = 0.006) and had a higher rate of unresectable disease, albeit not significantly (84% vs 68%, p = 0.1). EOPC patients were more frequently fit for surgery or chemotherapy than their counterpart, resulting in similar stage-specific survival probability. CONCLUSION: EOPC seems related to active and early smoking but not to familial syndromes. Young patients display aggressive disease but not worse outcome.

Human papillomavirus does not have a causal role in colorectal carcinogenesis.

AIM: To investigate the presence of human papillomavirus (HPV) DNA along with the integration, the quantification and the expression of the HPV16 in colorectal cancers. METHODS: A prospective series of colorectal tumors were genotyped for HPV DNA. The clinical and pathological variables of the HPV-positive tumors were compared to those of HPV-negative samples. The integration status of HPV16 was evaluated by calculating E2/E6 ng ratios. HPV16-positive tumors were also evaluated for (1) E2, E4, E5, E6 and E7 viral gene ng quantification; (2) relative quantification compared to W12 cells; and (3) viral E2, E4, E5, E6 and E7 mRNA transcripts by real-time polymerase chain reaction. RESULTS: HPV infection was detected in 16.9% of all tumors examined, and HPV16 was the most frequent type detected (63.6% of positive tissues). Notably, the clinical and pathological features of HPV-positive colorectal cancers were not significantly different than those of HPV-negative cancers (χ (2) and t-test for all clinical and pathological features of HPV-positive vs HPV-negative colorectal cancers: p ns). HPV16 DNA was present exclusively in episomal form, and the HPV16 E2, E4, E5, E6 and E7 genes were detected in trace nanogram quantities. Furthermore, the HPV16 genes ranged from 10(-3) to 10(-9) compared to W12 cells at an episomal stage. Although the extractions were validated by housekeeping gene expression, all the HPV16 positive tissues were transcriptionally inactive for the E2, E4, E5, E6 and E7 mRNAs. CONCLUSION: Based on our results, HPV is unlikely involved in colorectal carcinogenesis.

Standard versus limited colon resection for high risk T1 colon cancer. A matched case-control study.

BACKGROUND AND AIMS: The National Comprehensive Cancer Network (NCCN) recommends a colectomy in presence of high risk T1 colon polyps considering the risk of incomplete lymph node dissection or presence of residual disease. We evaluated the outcomes of segmental versus standard colon resection for high risk T1 colon cancers, in order to demonstrate if segmental colectomy (SegCR) allows same short-term and oncological results compared to standard radical colectomy (StaCR). METHODS. A matched case-control study on patients who had undergone segmental versus standard colon resection was performed. One-hundred and two patients with high risk T1 colon cancer after endoscopic polypectomy, divided in 2 homogeneous groups of 51 cases, were analyzed and intra-operative, post-operative and oncological data were compared. RESULTS. Segmental colectomy allowed less operative time and intra-operative blood loss compared to StaCR (p < 0.001). Hospital stay after SegCR was shorter compared to StaCR (p < 0.001). No differences were found in terms of overall morbidity and mortality rates. Five-year actuarial overall, disease-free and disease-specific survival after StaCR were similar to SegCR (87%, 96% and 95% vs. 88%, 97% and 94%, respectively, p = 0.51, p=0.33, p=0.78). CONCLUSIONS. According to our findings, SegCR can be a valid alternative to StaCR for high risk T1 colon polyps. Segmental colectomy allows better peri-operative outcomes compared to StaCR ensuring the same oncological long-term outcomes.

Is EUS-FNA of solid-pseudopapillary neoplasms of the pancreas as a preoperative procedure really necessary and free of acceptable risks?

BACKGROUND: Solid-pseudopapillary neoplasms (SPNs) of the pancreas are infrequent tumors since, as of 2014, only 2744 patients have been described. Its rarity, unclear histogenesis, pleomorphic aspect on radiology (cystic, solid or mixed) and unpredictable biological behavior with an insidious high-grade malignant potential make SPN difficult to recognize preoperatively even in its target patient population which is predominantly composed of young women (about 87% of cases). METHODS: Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) showed to improve the preoperative diagnostic yield for this tumor and obviate the risks formerly given by percutaneous biopsy. RESULTS: In light of our experience, such a procedure could not be so innocuous as generally acknowledged. CONCLUSION: We report the first case of rupture of pancreatic SPN following EUS-FNA and entertain both the actual and potential complications ensuing from this type of mishap.

Changes in the surgical approach to colonic emergencies during a 15-year period.

PURPOSE: The present study aims to determine the morbidity and mortality of emergency colonic surgery and the factors associated with adverse outcome, and to evaluate any change in incidence of the different types of pathological conditions and in the surgical approach over the last 15 years. MATERIALS AND METHODS: A total of 319 patients who underwent emergency colonic surgery between January 1997 and December 2011 were retrospectively analyzed. Patients were divided into two groups according to the date of surgery, namely group 1, between 1997 and 2006, and group 2, between 2006 and 2011. The differences in terms of postoperative outcomes between the groups were analyzed. RESULTS: Overall postoperative morbidity and mortality rates were 25.3 and 17.2%, respectively; no differences were found between the groups. Group 2 showed a significantly increased rate of primary resection and anastomosis (p < 0.001), as well as an increase in laparoscopic approach compared with group 1 (p < 0.001). CONCLUSIONS: Emergency colon surgery is today primarily performed for benign diseases, of these the most common is diverticular disease followed by ischemic colitis. Age, comorbidities, and ischemic colon disease are predictors of adverse outcomes, while the surgical procedure per se is not.

Acute abdomen: rare and unusual presentation of right colic xanthogranulomatosis.

Xanthogranulomatous inflammation (XGI) is a disease of unknown origin, most frequently described in the kidney and gallbladder; its localization in the colorectal tract is extremely rare. The extension of the typical inflammatory process to the surrounding tissues may lead to misdiagnosis as cancer. We report the case of a 56-year-old woman presenting to the Emergency Department with pain, increased levels of α1 and α2 proteins and C-reactive protein (17.5 mg/dL; normal value 0-0.5), and a palpable mass, localized in the right lower quadrant of the abdomen. A computed tomography scan showed a large right cecal mass with necrotic areas, local inflammation of retroperitoneal fat, and enlargement of local lymph nodes. Because of the high suspicion of colic abscess as well as malignancy and worsening of the clinical condition, the patient underwent right colectomy after 4 d of antibiotic treatment. Pathology revealed xanthogranulomatous inflammation involving the ileocecal valve. We review the reports of large bowel tract XGI in the international literature.

Prognostic assessment of different lymph node staging methods for pancreatic cancer with R0 resection: pN staging, lymph node ratio, log odds of positive lymph nodes.

BACKGROUND AND AIMS: Survival after surgical resection of pancreatic adenocarcinoma is poor. Several prognostic factors such as the status of the resection margin, lymph node status, or tumour grading have been identified. The aims of the present study were to evaluate and compare the prognostic assessment of different lymph nodes staging methods: standard lymph node (pN) staging, metastatic lymph node ratio (LNR), and log odds of positive lymph nodes (LODDS) in pancreatic cancer after pancreatic resection. MATERIALS AND METHODS: Data were retrospectively collected from 143 patients who had undergone R0 pancreatic resection for pancreatic ductal adenocarcinoma. Survival curves (Kaplan-Meier and Cox proportional hazard models), accuracy, and homogeneity of the 3 methods (LNR, LODDS, and pN) were compared to evaluate the prognostic effects. RESULTS: Multivariate analysis demonstrated that LODDS and LNR were an independent prognostic factors, but not pN classification. The scatter plots of the relationship between LODDS and the LNR suggested that the LODDS stage had power to divide patients with the same ratio of node metastasis into different groups. For patients in each of the pN or LNR classifications, significant differences in survival could be observed among patients in different LODDS stages. CONCLUSION: LODDS and LNR are more powerful predictors of survival than the lymph node status in patients undergoing pancreatic resection for ductal adenocarcinoma. LODDS allows better prognostic stratification comparing LNR in node negative patients.

Lymph-node ratio classification strongly correlates with cancer survivals of patients who underwent r0 resection for gastric cancer with more than 15 nodes harvested.

BACKGROUND: During the last few years, the gastric cancer nodal staging has been extensively revised. Lately, a new system emerged in this field with the purpose of implementing the prognostic stratification: the lymph-node ratio (LNR). The aim of this study was to investigate the prognostic value of the LNR in relation to cancer survivors undergoing resection for gastric adenocarcinoma. METHODS: Off 227 patients undergoing surgical resection for gastric cancer at our Department, 129 curative gastric resections with more than 15 nodes harvested were selected. The LNR was calculated and patients were stratified into 6 subgroups based on the ratio values. The subgroups were compared for data analysis. Survivals were calculated by the Kaplan-Meier method, and the mean follow-up period was 40 months. ROC curves were calculated in order to analyze the performance of the LNR system. RESULTS: LNR stratification correlated with the stage of the disease, with the rate of patients undergoing chemotherapy and patients presenting with a relapse of disease at follow-up. Moreover, an increased ratio correlated with a worse overall, a disease-free and a disease-specific survival of the patients. The ROC curves documented a significant performance of the stratification system with the endpoints of disease-free and disease-specific survivals. CONCLUSION: LNR stratification correlated with cancer-related survivals in our case series. It is a reliable system that might improve current nodal staging and thereby the identification of patients with a higher risk of recurrence or cancer-related mortality.
