Prognostic factors associated with overall survival in patients with oral cavity squamous cell carcinoma
2020
Background Low socioeconomic status, increasing age, and poor lifestyle behaviors are associated with poor survival in patients with oral cavity squamous cell carcinoma (OCSCC). To determine the overall survival (OS) and the risk of OCSCC death by tumor subsite. Material and Methods A retrospective cohort study of OCSCC patients diagnosed from 2007 to 2009 and treated at a single cancer center in Rio de Janeiro, Brazil. Patient information was obtained from the Hospital Cancer Registry (HCR) database and complemented by individual search of physical and electronic medical records. Descriptive statistics of population characteristics were computed. OS was estimated using the Kaplan-Meier met…
Outcome of radical prostatectomy for incidental carcinoma of the prostate
2009
OBJECTIVE To evaluate a contemporary series of patients with incidental prostate cancer detected by transurethral resection of the prostate (TURP) and undergoing radical prostatectomy (RP). PATIENTS AND METHODS Between 1998 and 2004, 1931 patients had TURP for obstructive voiding symptoms and suspected BPH. Incidental prostate cancer was found in 104 (5.4%); 26 of these patients had a RP. The pathological staging and treatment of these patients were reviewed retrospectively and the follow-up results obtained. RESULTS Of the 26 patients who had RP, 17 had T1a and nine had T1b carcinoma of the prostate. After RP, six (35%) in the T1a group had no residual tumour (pT0) and 11 (65%) had pT2 can…
Indications for preoperative prostate biopsy in patients undergoing radical cystoprostatectomy for bladder cancer.
2008
We determined indications for preoperative prostate biopsy in patients undergoing radical cystoprostatectomy for bladder cancer.Of 316 cystoprostatectomy specimens concomitant prostate cancer was diagnosed in 21.5%. Prostate cancer was diagnosed preoperatively in 24% of cases (evident prostate cancer), 32% were suspicious for prostate cancer but no biopsy was done (suspected prostate cancer) and in 44% prostate cancer was incidental. Patients were stratified into probability groups of intermediate/high risk prostate cancer by digital rectal examination and prostate specific antigen. The incidence of unfavorable histopathology was determined in each group.Of prostate cancers 85% were organ c…
Sentinel lymph node biopsy in malignant melanoma of the head and neck
2018
Abstract Background The aim of this retrospective study was to investigate sentinel lymph node biopsy in patients with head and neck melanoma. Materials and methods Patients who underwent SLNB between 2010 and 2016 were comprised. Epidemiological, radiological, and surgical data were collected and compared to histological findings. Patients who underwent primary complete lymph node dissection were excluded. Results 74 patients underwent SLNB during this period. The most common tumor localizations were the cheek (20.4%) and ears (20.4%). Overall, 256 sentinel lymph nodes (SLN) were detected and removed, most frequently in Robbins-levels IIA and IIB as well as in the surrounding of the paroti…
Impact of structured report on the quality of preoperative CT staging of pancreatic ductal adenocarcinoma: assessment of intra- and inter-reader vari…
2019
Purpose: To evaluate whether a structured radiology report improves the completeness of preoperative CT staging of pancreatic ductal adenocarcinoma (PDA) compared to conventional free-text reports. Methods: We retrospectively included 27 patients (mean age, 64 ± 11.1 years) referred for pancreatic preoperative CT scan for staging of PDA between 2015 and 2018 and in whom a diagnosis of pancreatic adenocarcinoma was ultimately confirmed. Four readers independently reported CT scans with both conventional free-text and structured reports. Differences in reported morphologic and vascular features with the two reports were assessed through McNemar Test. Intra-reader and inter-reader were calcula…
A Proposal for Novel Standards of Histopathology Reporting for D3 Lymphadenectomy in Right Colon Cancer: The Mesocolic Sail and Superior Right Colic …
2020
Background Strong agreement exists concerning the standards of pathologic reporting for total mesorectal excision and complete mesocolic excision. It represents a quality standard that correlates with survival. However, no agreed standards of reporting are available to define D3 lymphadenectomy for right colectomy. Objective The purpose of this study was to define anatomopathological standards of specimen quality obtained from the surgical specimen when an oncologic right hemicolectomy with D3 lymphadenectomy has been correctly performed. Design This study was conducted in 2 different phases. The first part consisted of a cadaver-based study of right colon anatomy, and the second part consi…

Long-term results of photodynamic therapy with 5-aminolevulinic acid for superficial Barrett's cancer and high-grade intraepithelial neoplasia
2005
Photodynamic therapy (PDT) with 5-aminolevulinic acid (ALA) has proven to be safe and effective in patients with early neoplasia in Barrett's esophagus. However, long-term results in patients with high-grade intraepithelial neoplasia (HGIN) or with early cancer are still lacking.The aim of the study was to evaluate the efficacy of ALA-PDT and the survival of patients with early Barrett's neoplasia. ALA-PDT was carried out in 66 patients. Protoporphyrin IX induced by oral administration of ALA (60 mg/kg body weight orally applied 4-6 hours before PDT) was used as the photosensitizer. Acid suppression was maintained in all patients.Between September 1996 and September 2002, 667 patients with …
Trends in the incidence and management of biliary tract cancer: a French population-based study.
2011
The trends in incidence and management of biliary tract cancer (BTC) were investigated in a well-defined French population over a 30-year period (1976-2005).Data were obtained from the Burgundy digestive cancer registry. Age-standardised incidence rates and trends in incidence were determined. Treatment and stage at diagnosis were also investigated. Five-year survival rates were calculated.Six hundred and fifteen cases of BTC were recorded. There was no significant change in BTC incidence over the 30-year period. For extrahepatic BTC age-standardised incidence rates were 1.1/100,000 for 1976-80 and 2001-2005. These rates were respectively 0.3 and 0.2/100,000 for intrahepatic BTC. The propor…
Oral cancer trends in a single head-and-neck cancer center in the Netherlands; decline in T-stage at the time of admission
2011
OBJECTIVES:In this study we evaluated the possible epidemiologic changes of oral cancer patients in the Netherlands between the years 1980-1984 and 2000-2004. We specifically studied the differences in male-female ratio, age, TNM-stage, site distribution, and alcohol and tobacco use.MATERIALS AND METHODS:Patients from the VU University Medical Center with an oral squamous cell carcinoma of the oral cavity registered in 1980-1984 (n=200), group 1, were compared to patients registered in 2000-2004 (n=184), group 2. Trends in prevalence, site distribution, TNM-stage, alcohol and tobacco use, age and gender were studied.RESULTS:The male-female ratio has decreased from 1.8 to 1.2. There were no …
