Selective approach to the treatment of oesophageal cancer
1996
Abstract Between September 1985 and December 1994, 322 patients with oesophageal cancer were treated. Of the 190 patients who underwent operation, 173 had an oesophageal resection; in 124 this was performed as an abdominothoracic resection and in 49 by the transhiatal approach. The assessment of radicality after histological examination revealed a curative (R0) resection in 121 patients (70 per cent) and a palliative (R1-R2) resection in 52 (30 per cent). Prognosis was correlated with the extent of mediastinal lymph node dissection. In 77 patients with stage pT1–3 pN0–1 pM0 the 5-year survival rate was 40 per cent after abdominothoracic resection with two-field lymph node dissection and zer…
Histopathological grading systems analysis of oral squamous cell carcinomas of young patients
2016
Background: To analyze the clinicopathological profile of young patients (≤ 40 years) with oral SCC and correlate with a control group (≥ 50 years) by means of histopathological grading systems. Material and Methods: 14 young patients and 14 control patients were selected with similar clinical stage and tumor location. Demographic and clinical data were obtained from patient records and histological sections were evaluated according to four histopathological grading systems. Associations between categories of demographic and clinical data were performed through Chi-square test and Exact Fisher test. The survival analyzes were performed according to the Kaplan-Meier method. Results: The comp…
Soluble intercellular adhesion molecule-1 (s-ICAM-1/s-CD54) in diffuse large B-cell lymphoma: association with clinical characteristics and outcome
2003
Background: High serum levels of soluble intercellular adhesion molecule-1(s-ICAM-1/s-CD54) have been associated with adverse clinical features and poor outcome in chronic lymphocytic leukemia, Hodgkin’s disease and non-Hodgkin’s lymphoma, but their value in the different subtypes of non-Hodgkin’s lymphoma has not been well addressed. Patients and methods: Our aim was to study the serum levels of s-ICAM-1 in diffuse large B-cell lymphoma (DLBCL) and to correlate them with clinical characteristics and outcome. We analyzed the serum levels of s-ICAM-1 in a series of 55 patients with DLBCL diagnosed in a single institution. s-ICAM-1 levels were quantified by an immunoenzymatic assay. Median ag…
Clinicopathological analysis of 1571 cutaneous malignant melanomas in Valencia, Spain: factors related to tumour thickness.
2006
Epidemiological studies on cutaneous melanoma in Mediterranean countries are scarce. Our aim was to perform a descriptive analysis of melanoma cases diagnosed in Valencia, Spain, and to evaluate the relationship between Breslow thickness and some clinical features. A total of 1571 patients with histologically confirmed cutaneous malignant melanoma diagnosed at the two main referral melanoma centres were evaluated retrospectively. For each patient the following clinical and pathological characteristics were selected: age, gender, anatomic site, histogenetic type, Breslow thickness, presence of ulceration, the stage, and symptoms such as bleeding, changes in size and colour, altered sensation…
Presurgical Ultrasound-Guided Anchor-Wire Marking of Soft Tissue Metastases in Stage III Melanoma Patients
2001
Background. Due to increased sensitivity of diagnostic procedures, soft tissue metastases in melanoma patients are frequently detected very early. However, small sizes, deep location, or position close to vulnerable structures could render subsequent surgery quite difficult. Objective. To test the feasibility and effectiveness of presurgical ultrasound-guided anchor-wire marking of melanoma metastases. Methods. We selected melanoma patients with cytologically proven metastases in clinical stage III which were either unfavorably located or which have failed removal by previous surgery. Anchor-wire marking was performed ultrasound guided and free-hand style without the use of local anesthesia…
Large left ventricular metastatis in patient with liposarcoma.
2014
Abstract Metastasis to the heart and pericardium are rare. We present a 44-year-old male with pleural dedifferentiated liposarcoma and multiple metastases, with no previous cardiological history and/or cardiac symptoms. A transthoracic echocardiogram during the advanced stage of disease showed a lobulated, large and mobile mass, with homogeneous echogenicity, attached to the basal posterior wall of the left ventricle via a broad base and with intracavitary growth. This mass extends to inferolateral and inferoseptal wall of the left ventricle.
The clinical use of statistical permutation test methodology: a tool for identifying predictive variables of outcome.
2015
<b><i>Objectives:</i></b> To identify the predictive variables affecting the outcome after radical surgery for bladder cancer by a newer statistical methodology, i.e. nonparametric combination (NPC). <b><i>Methods:</i></b> A multicenter study enrolled 1,312 patients who had undergone radical cystectomy for bladder cancer in 11 Italian oncological centers from January 1982 to December 2002. A statistical analysis<b> </b>of their medical history and diagnostic, pathological and postoperative variables was performed using a NPC test. The<b> </b>patients were included in a comprehensive database with medical history and cli…
Computerized tomography: an unreliable method for accurate staging of bladder tumors in patients who are candidates for radical cystectomy.
1989
A total of 164 patients with bladder tumors underwent preoperative staging by computerized tomography. All patients were previously untreated, or had undergone only transurethral biopsy or resection of the tumor before computerized tomography. The post-cystectomy histological stage was compared to the preoperative computerized tomography stage. Computerized tomography accuracy according to the tumor, nodes and metastasis classification was only 32.3%, whereas overstaging was found in 39.6% and understaging in 28.1% of the cases. In untouched tumors or after transurethral resection computerized tomography accuracy demonstrated no significant difference. Only 2 of 19 true positive lymph nodes…
Cancer-specific survival after radical cystectomy and standardized extended lymphadenectomy for node-positive bladder cancer: prediction by lymph nod…
2009
OBJECTIVE To investigate the associations between different overall or topographically restricted lymph node (LN) variables and cancer-specific survival (CSS) after radical cystectomy (RC) and extended LN dissection (LND) with curative intent in patients with LN-positive bladder cancer. PATIENTS AND METHODS Between 2001 and 2006, 152 patients had RC with standardized extended LND for bladder cancer with curative intent. Patients with positive LNs were stratified according to the median of the LN variables (LNs removed, number of positive LNs, LN density). CSS was related to overall and topographically restricted LN variables, e.g. different levels of LND, and relationships were tested by un…
Radical cystectomy with or without adjuvant polychemotherapy for non-organ-confined transitional cell carcinoma of the urinary bladder: prognostic im…
1996
To analyze the effectiveness of adjuvant polychemotherapy after radical cystectomy for non-organ-confined transitional cell bladder cancer (Stages pT3b, pT4a, and/or pN1 or pN2).Of 166 consecutive patients undergoing cystectomy at two institutions from 1987 to 1993, 80 received adjuvant polychemotherapy with methotrexate, vinblastine, and cisplatin plus doxorubicin (MVAC) or epirubicin (MVEC), whereas 86 had cystectomy only. The patients were evaluated for relapse-free survival and length of progression-free interval on the basis of follow-up data obtained in 1995 and 1996.Kaplan-Meier analysis revealed a significantly higher progression-free rate for patients after adjuvant chemotherapy (P…
