Pheochromocytoma in the Pediatric Age Group: The Prostate—An Unusual Location
1990
AbstractPheochromocytomas of the prostate are rare, with only 3 cases in adults reported in the literature. We present the case of an 8-year-old boy with a pheochromocytoma of the prostate and a second tumor in the region of the left internal iliac artery. (J. Urol., 144: 1219–1221, 1990)
High frequency of colorectal adenoma in patients with duodenal adenoma but without familial adenomatous polyposis
2004
Abstract Background Duodenal adenomas are extremely common in patients with familial adenomatous polyposis. However, it is uncertain whether patients with duodenal adenomas without familial adenomatous polyposis are at greater risk for colorectal neoplasia and, therefore, should routinely undergo surveillance colonoscopy. The aim of this study was to determine whether there is a correlation between non-papillary duodenal adenoma without familial adenomatous polyposis and colorectal adenoma. Methods Twenty-five patients with non-papillary duodenal adenomas without familial adenomatous polyposis, seen from January 1990 to April 2003, were retrospectively evaluated. Results Non-papillary duode…
Exome and immune cell score analyses reveal great variation within synchronous primary colorectal cancers
2019
BACKGROUND: Approximately 4% of colorectal cancer (CRC) patients have at least two simultaneous cancers in the colon. Due to the shared environment, these synchronous CRCs (SCRCs) provide a unique setting to study colorectal carcinogenesis. Understanding whether these tumours are genetically similar or distinct is essential when designing therapeutic approaches. METHODS: We performed exome sequencing of 47 primary cancers and corresponding normal samples from 23 patients. Additionally, we carried out a comprehensive mutational signature analysis to assess whether tumours had undergone similar mutational processes and the first immune cell score analysis (IS) of SCRC to analyse the interplay…
Development and Validation of a New Prognostic System for Patients with Hepatocellular Carcinoma
2016
Background Prognostic assessment in patients with hepatocellular carcinoma (HCC) remains controversial. Using the Italian Liver Cancer (ITA.LI.CA) database as a training set, we sought to develop and validate a new prognostic system for patients with HCC. Methods and Findings Prospective collected databases from Italy (training cohort, n = 3,628; internal validation cohort, n = 1,555) and Taiwan (external validation cohort, n = 2,651) were used to develop the ITA.LI.CA prognostic system. We first defined ITA.LI.CA stages (0, A, B1, B2, B3, C) using only tumor characteristics (largest tumor diameter, number of nodules, intra- and extrahepatic macroscopic vascular invasion, extrahepatic metas…
Epidemiology and prognosis of synchronous and metachronous colon cancer metastases: a French population-based study.
2014
Epidemiological data on synchronous and metachronous metastatic colon cancer are scarce. We assessed epidemiological characteristics and survival in synchronous and metachronous metastatic colon cancer in a French population.Our study included 932 cases of metastatic colon cancer diagnosed in 1999-2010 and registered in a population-based cancer registry; 758 were synchronous colon metastases and 174 metachronous metastases from resected primary colon cancers diagnosed in 1999-2005. Univariate relative survival was calculated and a multivariate model with proportional hazard applied to net survival by interval was used.Mean age at diagnosis was 71.1 years for patients with metachronous meta…
Proliferative verrucous leukoplakia, squamous cell carcinoma and axillary metastasis.
2009
Proliferative verrucous leukoplakia (PVL) is an aggressive form of oral leukoplakia with multifocal presentation, high rates of recurrence and malignant transformation. Although development of regional lymph node metastasis is relatively frequent in patients with oral squamous cell carcinoma, axillary metastasis is quite uncommon. This paper presents a case of a 64-year-old female patient who was diagnosed with PVL and developed five oral squamous cell carcinomas and later an axillary lymph node metastasis.
Synchronous Two Distinct Neuroendocrine Lung Cancer Lesions
2015
Synchroniczne nowotwory płuc są rzadką chorobą, a prezentowany przypadek to pierwszy opublikowany opis jednoczesnego wystąpienia dwóch pierwotnych neuroendokrynnych raków płuca zlokalizowanych w jednym płacie. Przedstawiono przypadek 55-letniej pacjentki z dwoma pierwotnymi, odrębnymi neuroendokrynnymi rakami płata górnego płuca prawego. Pacjentka została przyjęta na oddział chirurgii klatki piersiowej w celu diagnostyki dwóch cieni okrągłych płuca prawego (o średnicy 11 i 19 mm) uwidocznionych na zdjęciu RTG klatki piersiowej wykonanym trzy miesiące wcześniej. Przy przyjęciu pacjentka nie prezentowała żadnych objawów związanych ze zmianami w płucu. Dalsze badania obrazowe wykazały zmiennoś…
Imperative and Elective Indications for Nephron-Sparing Surgery for Renal Tumors: Long-Term Oncological Follow-Up
2010
INTRODUCTION: Nephron-sparing surgery (NSS) is mandatory for patients with renal tumors in both kidneys or in a solitary kidney in order to preserve renal function (imperative indication). NSS has also become the gold standard (elective indication) for small unilateral renal tumors (< 4 cm) with a normal contralateral kidney. We report the oncological long-term follow-up of NSS of our own series and discuss the results of the current literature. PATIENTS AND METHODS: From 1979 until 2006, a total of 851 patients was treated at our institu-tion by NSS. The mean tumor diameter was 3 cm (0.5-11 cm) for elective cases and 4.2 cm (1.2-11 cm) for imperative cases. The median follow-up for electiv…
Intrahepatic cholangiocarcinoma: Limitations for resectability, current surgical concepts and future perspectives.
2020
Intrahepatic cholangiocarcinoma (iCCA) is the second most common hepatic malignancy and its incidence has been shown to increase significantly during the past decades. Complete surgical resection is currently acknowledged as the only curative treatment option able to provide adequate long-term outcomes. We herein review technical, functional and oncologic limitations for resectability, discuss current surgical aspects as well as highlight the fields in which future research and practice should focus on in order to ameliorate long-term outcomes in patients with iCCA.
Synchronous Ovarian and Endometrial Cancer—an International Multicenter Case-Control Study
2013
ObjectivesThis study aimed to compare the prognosis of patients with synchronous endometrial and ovarian cancer (SEOC) to matched controls with either endometrial cancer (EC) or ovarian cancer (OC).MethodsA retrospective case-control study including all patients with SEOC who had been treated at 5 European tertiary gynecologic oncology centers between 1996 and 2011 and patients with either EC or OC matched for age, International Federation of Gynecology and Obstetrics (FIGO) stage, histology, year of diagnosis, and Eastern Cooperative Oncology Group performance score.ResultsThe study cohort comprised 77, 132, and 126 patients with SEOC, EC, and OC, respectively. The patient characteristics …
