Specific TP53 and/or Ki-ras mutations as independent predictors of clinical outcome in sporadic colorectal adenocarcinomas: results of a 5-year Grupp…
2005
BACKGROUND: Although Ki-ras and TP53 mutations have probably been the genetic abnormalities most exhaustively implicated and studied in colorectal cancer (CRC) progression, their significance in terms of disease relapse and overall survival has not yet clearly been established. PATIENTS AND METHODS: A prospective study was carried out on paired tumor and normal colon tissue samples from a consecutive series of 160 previously-untreated patients, undergoing resective surgery for primary operable sporadic CRC. Mutations within the TP53 (exons 5-8) and Ki-ras (exon 2) genes were detected by PCR-SSCP analyses following sequencing. RESULTS: Mutation analyses of exons 5 to 8 of the TP53 gene showe…
Features and management of men with pN1 cM0 prostate cancer after radical prostatectomy and lymphadenectomy: a systematic review of population-based …
2021
Purpose of review To investigate the features and optimal management of pN+ cM0 prostate cancer (PCa) according to registry-based studies. Recent findings Up to 15% of PCa patients harbor lymph node invasion (pN+) at radical prostatectomy plus lymph node dissection. Nonetheless, the optimal management strategy in this setting is not well characterized. Summary We performed a systematic review including n = 13 studies. Management strategies comprised 13 536 men undergoing observation, 11 149 adjuvant androgen deprivation therapy (aADT), 7,075 adjuvant radiotherapy (aRT) +aADT and 705 aRT. Baseline features showed aggressive PCa in the majority of men. At a median follow-up ranging 48-134mont…

Completion Surgery After Concomitant Chemoradiation in Locally Advanced Cervical Cancer: A Comprehensive Analysis of Pattern of Postoperative Complic…
2014
Background: We provided a comprehensive analysis of rate, pattern, and severity of early and late postoperative complications in a very large, single-institution series of locally advanced cervical cancer (LACC) patients administered CT/RT plus radical surgery (RS). Methods: A total of 362 consecutive LACC (FIGO stage IB2-IVA) patients were submitted to RS after CT/RT at the Gynecologic Oncology Unit of the Catholic University (Rome/Campobasso). At 4 weeks after CT/RT, patients were evaluated for objective response and triaged to radical hysterectomy and pelvic ± aortic lymphadenectomy. Surgical morbidity was classified according to the Chassagne's grading system. Results: Most cases underw…

Quality analysis of population-based information on cancer stage at diagnosis across Europe, with presentation of stage-specific cancer survival esti…
2017
Abstract Background Cancer registries (CRs) are fundamental for estimating cancer burden, evaluating screening and monitoring health service performance. Stage at diagnosis—an essential information item collected by CRs—has been made available, for the first time, by CRs participating in EUROCARE-5. We analysed the quality of this information and estimated stage-specific survival across Europe for CRs with good data quality. Data and methods Sixty-two CRs sent stage (as TNM, condensed TNM or extent of disease) for 15 cancers diagnosed in 2000–2007. We assessed the quality, partly by comparing stage according to the three systems. We also developed procedures to reconstruct stage (categories…
Survival benefit of liver resection for patients with hepatocellular carcinoma across different Barcelona Clinic Liver Cancer stages: a multicentre s…
2015
Background & Aims The role of hepatic resection for hepatocellular carcinoma (HCC) in different Barcelona Clinic Liver Cancer (BCLC) stages is controversial. We aimed at measuring the survival benefit of resection vs. non-surgical-therapies in each BCLC stage. Methods Using the ITA.LI.CA database, we identified 2090 BCLC A, B, and C HCC patients observed between 2000 and 2012: 550 underwent resection, 1046 loco-regional therapy (LRT), and 494 best supportive care (BSC). A multivariate log-logistic model was chosen to predict median survival (MS) after resection vs. MS after LRT or BSC. The results were expressed as net survival benefit of resection: (MS resection - MS LRT)/MS BSC. Resul…
The SIC-GIRCG 2013 Consensus Conference on Gastric Cancer.
2014
Abstract The topic chosen by the Board of the Italian Society of Surgery for the 2013 annual Consensus Conference was gastric cancer. With this purpose, under the direction of 2 chairmen, 36 experts nominated by the Regional Societies of Surgery and by the Italian Research Group for Gastric Cancer (GIRCG) participated in an experts consensus exercise, preceded by a questionnaire and mainly held by telematic vote, in accordance with the rules of the Delphi method. The results of this Consensus Conference, presented to the 115th National Congress of the Italian Society of Surgery, and approved in plenary session, are reported in the present paper.
Perfusion computed tomography of intracranial meningiomas: In vivo correlation of cerebral blood volume and vascular permeability
2015
Background A noninvasive method to predict the grade of a meningioma would be desirable since it would anticipate information about tumour nature, recurrence and improve tumour management and outcomes. The aim of the present study was to assess the ability of perfusion computed tomography (PCT) technique in predicting the meningioma grade before surgery. Data from PCT, such as cerebral blood volume (CBV) and permeability surface (PS), were correlated with immunohistolopathological information. Methods Twenty-three patients with a diagnosis of intracranial meningioma underwent PCT for pre-surgical evaluation of CBV and PS. During surgery, samples from the centre and periphery of the tumour w…
The impact of re-transurethral resection on clinical outcomes in a large multicentre cohort of patients with T1 high-grade/Grade 3 bladder cancer tre…
2015
Objectives To determine if a re-transurethral resection (TUR), in the presence or absence of muscle at the first TUR in patients with T1-high grade (HG)/Grade 3 (G3) bladder cancer, makes a difference in recurrence, progression, cancer specific (CSS) and overall survival (OS). Patients and methods In a large retrospective multicentre cohort of 2451 patients with T1-HG/G3 initially treated with bacille Calmette–Gu erin, 935 (38%) had a re-TUR. According to the presence or absence of muscle in the specimen of the primary TUR, patients were divided in four groups: group 1 (no muscle, no re-TUR), group 2 (no muscle, re-TUR), group 3 (muscle, no re-TUR) and group 4 (muscle, re-TUR). Clinical out…
