Role of preoperative CT angiography with multimodality imaging reconstruction to perform laparoscopic Complete Mesocolic Excision (CME) and Central V…
2022
Background: The concept of complete mesocolic excision (CME) and central vascular ligation (CVL) in right colonic resections appears to improve the oncological outcomes. The highest rate of complications reported in the literature in patients undergoing CME is related to difficult surgical manuevers and intraoperative bleeding due to the central vascular dissection. Methods: We used preoperative findings obtained with the CT angiography, multiplanar reformation (MPR), maximum intesity projection (MIP) and 3D volume rendering (VR) technique to verify if this preoperative radiological assessment had significant benefits regarding the difficulty of dissection of the embryological planes, the i…
Endometrial carcinoma with tibial bone metastasis: a case report and literature review.
2018
Endometrial cancer is the most common female genital malignancy and the seventh most common cause of death from cancer in women in Western countries. The median age of occurrence is 63 years, while...
Papillary thyroid microcarcinoma: extrathyroidal extension, lymph node metastases and risk factors for recurrence in a high prevalence of goiter area
2010
BACKGROUND. Papillary thyroid microcarcinoma (PTMC) is diagnosed with increasing frequency. Since risk factors for an aggressive clinical behavior have not been clearly delineated, the best therapeutic option and follow up protocol for PTMC have not been established yet, especially in case of incidental diagnosis after partial thyroidectomy for benign disease. We reviewed our series of patients with PMTC to determine risk factors for recurrence in a high prevalence of goiter area. METHODS. The medical records of all the patients who underwent total thyroidectomy (TT) with a final pathology report of PTMC between October 2002 and June 2007 were reviewed. Demographic, clinical and pathologica…
Prediction of Non-sentinel Node Status in Patients with Melanoma and Positive Sentinel Node Biopsy: An Italian Melanoma Intergroup (IMI) Study
2018
Background and Purpose: Approximately 20% of melanoma patients harbor metastases in non-sentinel nodes (NSNs) after a positive sentinel node biopsy (SNB), and recent evidence questions the therapeutic benefit of completion lymph node dissection (CLND). We built a nomogram for prediction of NSN status in melanoma patients with positive SNB. Methods: Data on anthropometric and clinicopathological features of patients with cutaneous melanoma who underwent CLND after a positive SNB were collected from nine Italian centers. Multivariate logistic regression was utilized to identify predictors of NSN status in a training set, while model efficiency was validated in a validation set. Results: Data …
Testicular germ-cell tumours and penile squamous cell carcinoma: Appropriate management makes the difference
2019
Germ-cell tumours (GCT) of the testis and penile squamous cell carcinoma (PeSCC) are a rare and a very rare uro-genital cancers, respectively. Both tumours are well defined entities in terms of management, where specific recommendations - in the form of continuously up-to-dated guide lines- are provided. Impact of these tumour is relevant. Testicular GCT affects young, healthy men at the beginning of their adult life. PeSCC affects older men, but a proportion of these patients are young and the personal consequences of the disease may be devastating. Deviation from recommended management may be a reason of a significant prognostic worsening, as proper treatment favourably impacts on these t…
The role of sentinel node tumor burden in modeling the prognosis of melanoma patients with positive sentinel node biopsy: an Italian melanoma intergr…
2022
Abstract Background: The management of melanoma patients with metastatic sentinel nodes (SN) is evolving based on the results of trials questioning the impact of completion lymph node dissection (CLND) and demonstrating the efficacy of new adjuvant treatments. In this landscape, new prognostic tools for fine risk stratification are eagerly sought to optimize the therapeutic path of these patients. Methods: A retrospective cohort of 2,086 patients treated with CLND after a positive SN biopsy in thirteen Italian Melanoma Centers was reviewed. Overall survival (OS) was the outcome of interest; included independent variables were the following: age, gender, primary melanoma site, Breslow thickn…
Predicting survival in node-positive prostate cancer after open, laparoscopic or robotic radical prostatectomy: A competing risk analysis of a multi-…
2016
Objectives: To investigate cancer-specific mortality and other-cause mortality in prostate cancer patients with nodal metastases. Methods: The study included 411 patients treated with radical prostatectomy and pelvic lymph node dissection for prostate cancer with lymph node metastases at 10 tertiary care centers between 1995 and 2014. Kaplan–Meier analyses were used to assess cancer-specific mortality-free survival rates at 8 years' follow up in the overall population, and after stratifying patients according to clinical and pathological parameters. Uni- and multivariable competing risk Cox regression analyses were used to assess cancer-specific mortality and other-cause mortality. Finally,…
Mesenteric Lymph Node Involvement in Advanced Ovarian Cancer Patients Undergoing Rectosigmoid Resection: Prognostic Role and Clinical Considerations
2014
Background: The aim of this retrospective study was to investigate the incidence of mesenteric lymph node (MLN) involvement, and its prognostic role in advanced ovarian cancer (OC). Methods: OC patients undergoing rectosigmoid resection during primary debulking surgery or interval debulking surgery were recorded. Progression-free survival (PFS) and overall survival were calculated from the date of diagnosis to the date of relapse/progression, death of disease, or the date of last follow-up. Results: MLNs were detected in 102/148 cases (68.9 %); the rate of MLN involvement was 47.0 %. The percentage of metastatic MLNs was higher in cases with >5 MLNs removed compared with cases with ≤5 MLNs …
First results for resetting the antitumor immune response by immune corrective surgery in colon cancer.
1998
BACKGROUND: A critical step for cancer recurrence is the failure of the cellular immune response. It is suspected that chronic humoral immune responses against some tumor-associated antigens (TAA) can contribute to that failure. METHODS: In this study, we tested the ability of an immune corrective surgical procedure to prevent recurrences of colon cancer in stages I, II, and III. Radiolabeled anti-TAG antibodies injected intravenously become concentrated on TAG-72 immune complexes presented by follicular dendritic cells, which are responsible for the persistent humoral response against TAG-72 TAA. Using a hand-held gamma probe, we can intraoperatively detect and remove lymph nodes involved …
Risk of lymph node metastasis in submucosal esophageal cancer: a review of surgically resected patients
2011
Endoscopic local procedures are increasingly applied in patients with superficial esophageal cancer as an alternative to radical oncologic resection. The objective of this article is to determine the risk of nodal metastases in submucosal (sm) esophageal cancer, comparing the two predominating histologic tumor types, squamous cell cancer (SCC) and adenocarcinoma (ADC).A query of PubMed, MEDLINE, Embase and Cochrane Library (1980-2009) using predetermined search terms revealed 675 abstracts, of which 485 full-text articles were reviewed. A total of 105 articles met the selection criteria. A review of article references and consultation with experts revealed additional articles for inclusion.…
