Upper lip malignant neoplasms : a study of 59 cases
2011
Objectives: To present the demographic data, clinico-pathologic features and therapeutic outcome of a series of upper lip malignancies. Study Design: Retrospective study at a single Cancer Institution in Mexico City during a 14-year period. Results: There were 59 cases, (30 males and 29 females); age range: 14 to 106 years (mean: 73 yr.). Antecedents of ultraviolet light and tobacco exposure were found in 20 (33.9%) and 16 cases (27%) respectively. There were 35 squamous cell carcinomas (59.3%), 19 basal cell carcinomas (32.2%) and one case each (1.7%) of adenocarcinoma NOS, adenoid cystic carcinoma, angiosarcoma, Merkel cell carcinoma and melanoma. There were 14 cases in stage I (23.7%), 1…
Solid bone tumors of the spine: Diagnostic performance of apparent diffusion coefficient measured using diffusion-weighted MRI using histology as a r…
2017
Purpose To assess the diagnostic performance of mean apparent diffusion coefficient (mADC) in differentiating benign from malignant bone spine tumors, using histology as a reference standard. Conventional magnetic resonance imaging (MRI) sequences have good reliability in evaluating spinal bone tumors, although some features of benign and malignant cancers may overlap, making the differential diagnosis challenging. Materials and Methods In all, 116 patients (62 males, 54 females; mean age 59.5 ± 14.1) with biopsy-proven spinal bone tumors were studied. Field strength/sequences: 1.5T MR system; T1-weighted turbo spin-echo (repetition time / echo time [TR/TE], 500/13 msec; number of excitatio…
Trends in excess mortality in follicular lymphoma at a population level
2015
Background Since the 1990s and since the development of humanised monoclonal antibodies in 1998, the treatment of non-Hodgkin lymphoma has undergone profound changes. Follicular lymphoma (FL) was the first to benefit from this treatment, and several clinical trials have shown a significant improvement in overall survival, but little information is available at a population level. Objective Our objective was to estimate changes in FL-specific mortality at a population level, with an appropriate methodology. Methods Two French retrospective population-based studies on FL were conducted, one from 1995 to 2004, in 1477 patients, and one from 1995 to 2010, in 451 patients. Trends in excess morta…
Nomograms including nuclear matrix protein 22 for prediction of disease recurrence and progression in patients with Ta, T1 or CIS transitional cell c…
2005
ABSTRACT Purpose: We developed and validated nomograms that accurately predict disease recurrence and progression in patients with Ta, T1, or CIS transitional cell carcinoma (TCC) of the bladder using a large international cohort. Methods: Univariate and multivariate logistic regression models targeted histologically confirmed disease recurrence, and focused on 2,542 patients with bladder TCC from 10 participating centers. Variables consisted of pre-cystoscopy voided urine Nuclear Matrix Protein 22 (NMP22) assay, urine cytology, age and gender. Resulting nomograms were internally validated with bootstrapping. Nomogram performance was explored graphically with Loess smoothing plots. Results:…
Response-guided ABVD chemotherapy plus involved-field radiation therapy for intermediate-stage Hodgkin lymphoma in the pre-positron emission tomograp…
2009
Abstract Purpose In the pre—positron emission tomography era, the Gruppo Italiano Studio Linfomi (GISL) investigated the feasibility and efficacy of a treatment based on a response-tailored number of doxorubicin/bleomycin/vinblastine/dacarbazine (ABVD) courses in 218 intermediate-stage Hodgkin lymphoma patients. Patients and Methods Patients with stage I/II showing at least one adverse prognostic factor and stage IIIA without adverse prognostic factors were recruited. Treatment included a first step of 3 ABVD courses, followed by an early-restaging. Patients in CR/CRu received 1 additional ABVD cycle, patients in PR received 3 more ABVD, and nonresponder patients went off study. Involved-fi…
Increased C-reactive protein implies a poorer stage-specific prognosis in colon cancer.
2013
To characterize the stage-specific prognostic relevance of preoperative systemic inflammatory response, defined by C-reactive protein (CRP), in colon cancer (CC) patients.Data from CC patients operated on from 1998 to 2007 at three hospitals from three different Nordic countries were collected retrospectively from national registries, local databases and/or patient records. Patients with emergency surgery, infection or auto-immune disease were excluded. Associations between clinical or histopathological variables and CRP were assessed. Patients were followed from the date of surgery to death or end of follow-up. Disease-specific survival (DSS) was the main endpoint.In total, 525 patients wi…
Modified Wong's Classification Improves the Accuracy of Rectal Cancer Staging by Endorectal Ultrasound and MRI
2013
BACKGROUND: Douglas Wong proposed a new classification of tumor penetration in the rectal wall (T stage) in an attempt to incorporate the prognostic heterogeneity of T3 rectal cancers into the preoperative staging. OBJECTIVE: This study aimed to evaluate if the accuracy of endorectal ultrasound and MRI in predicting rectal cancer T staging improves when using a modified Wong's classification. DESIGN: This prospective series compares local standard TN staging and a modified Wong's classification. SETTINGS: This study was conducted by a specialized Colorectal Multidisciplinary Team at a tertiary teaching hospital. PATIENTS: Seventy patients underwent surgery for middle or low rectal cancer be…
Avoidance of Overtreatment of Rectal Cancer by Selective Chemoradiotherapy: Results of the Optimized Surgery and MRI-Based Multimodal Therapy Trial.
2020
Background Neoadjuvant chemoradiotherapy (nCRT) in patients with rectal cancer carries a high risk of adverse effects. The aim of this study was to examine the selective application of nCRT based on patient risk profile, as determined by MRI, to find the optimal range between undertreatment and overtreatment. Study Design In this prospective multicenter observational study, nCRT before total mesorectal excision (TME) was indicated in high-risk patients with involved or threatened mesorectal fascia (≤1 mm), or cT4 or cT3 carcinomas of the lower rectal third. All other patients received primary surgery. Results Of the 1,093 patients, 878 (80.3%) were treated according to the protocol, 526 pat…
Survival differences between European and US patients with colorectal cancer: role of stage at diagnosis and surgery
2005
Background: Population based colorectal cancer survival among patients diagnosed in 1985–89 was lower in Europe than in the USA (45% v 59% five year relative survival). Aims: To explain this difference in survival using a new analytic approach for patients diagnosed between 1990 and 1991. Subjects: A total of 2492 European and 11 191 US colorectal adenocarcinoma patients registered by 10 European and nine US cancer registries. Methods: We obtained clinical information on disease stage, number of lymph nodes examined, and surgical treatment. We analysed three year relative survival, calculating relative excess risks of death (RERs, referent category US patients) adjusted for age, sex, site, …
Factors related to late stage diagnosis of oral squamous cell carcinoma.
2010
Aims: To identify factors related to advanced-stage diagnosis of oral cancer to disclose high-risk groups and facilitate early detection strategies. Study design: An ambispective cohort study on 88 consecutive patients treated from January 1998 to December 2003. Inclusion criteria: pathological diagnosis of OSCC (primary tumour) at any oral site and suffering from a tumour at any TNM stage. Variables considered: age, gender, smoking history, alcohol usage, tumour site, macroscopic pattern of the lesion, co-existing precancerous lesion, degree of differentiation, diagnostic delay and TNM stage. Results: A total of 88 patients (mean age 60±11.3; 65.9% males) entered the study. Most patients (…
