AIM: TNM staging and histological grading of rectal cancer has undergone no or minimal changes during the past 20 years despite their major impact on planning, reporting and outcome of the disease. The addition of category 'F' to the 'TNM' staging of colorectal cancer, which becomes TNMF will accommodate the expanding list of risk factors that may affect the management and thus avoid squeezing them into the TNM categories. METHODS: Reporting of the following risk factors was traced in 730 (664 retrospective and 66 prospective) cases of colorectal cancer: age, Tumor location, preoperative CEA, intraoperative tumor perforation and blood transfusion, quality of TME, tumor grade, non nodal T...

Immunologic profiling of colorectal cancer (CRC) may help to predict the tumors metastatic potential and patients with an aggressive tumor, although not yet metastasized at time of surgery might benefit from adjuvant therapy. In this study we evaluated the prognostic significance of FOXP3(+) T regulatory cells (Tregs), CD3(+) and CD8(+) lymphocyte densities and conventional histopathologic features in nodal negative (n = 820, UICC stage II) CRC. Immunohistochemical studies showed that high expression of FOXP3(+) Tregs is significantly linked to a better clinical outcome (P = 0...

AIM: Microarray studies identified a subgroup of molecular apocrine tumors (estrogen receptor [ER] negative/androgen receptor [AR] positive) that express luminal genes including FOXA1. FOXA1 may direct AR to sites normally occupied by ER in luminal tumors, inducing an estrogen-like gene program that stimulated proliferation. MATERIALS & METHODS: Expression of AR and FOXA1 was evaluated by immunohistochemistry in 592 patients with nonmetastatic triple-negative breast cancer (TNBC)...

Colorectal cancer (CRC) is the most common type of gastrointestinal cancer and has three major pathways of carcinogenesis. About 80% of genomic instability concerns chromosomal instability (CIN); the rest is connected with either microsatellite instability (MSI) or CpG island methylation. Some MSI-related cancers are associated with Lynch syndrome, whereas others are caused by sporadic, acquired hypermethylation of the promoter of the MLH1 gene. These tumours have distinctive clinical and histopathological features...

AIMS: Information on tumour border configuration (TBC) in colorectal cancer (CRC) is currently not included in most pathology reports, owing to lack of reproducibility and/or established evaluation systems. The aim of this study was to investigate whether an alternative scoring system based on the percentage of the infiltrating component may represent a reliable method for assessing TBC. METHODS AND RESULTS: Two hundred and fifteen CRCs with complete clinicopathological data were evaluated by two independent observers, both 'traditionally' by assigning the tumours into pushing/infiltrating/mixed categories, and alternatively by scoring the percentage of infiltrating margin...

REVIEW

Histomorphological features of colorectal cancers (CRC) represent valuable prognostic indicators for clinical decision making. The invasive margin is a central feature for prognostication shaped by the complex processes governing tumor-host interaction. Assessment of the tumor border can be performed on standard paraffin sections and shows promise for integration into the diagnostic routine of gastrointestinal pathology. In aggressive CRC, an extensive dissection of host tissue is seen with loss of a clear tumor-host interface...

BACKGROUND: Pancreatic paragangliomas are rare tumors, with only 16 reported cases to date. One of these cases demonstrates metastasis to lymph node, while another case was functional, however, none of these cases showed malignant and large, pancreatic paraganglioma with marked invasion. Also another unique feature was the age of our patient compared to the average reported ages in published literature (42-85 years). CASE PRESENTATION: A 19-year-old woman presented with a one-year history of intermittent abdominal pain...

Available data correlating symptoms of colon cancer patients with the severity of the disease are very limited. In a population-based setting, we correlated information on symptoms of colon cancer patients with several pathological tumor parameters and survival. Information on all patients diagnosed with colon cancer in Iceland in 1995-2004 for this retrospective, population-based study was obtained from the Icelandic Cancer Registry. Information on symptoms of patients and blood hemoglobin was collected from patients' files...

Although most breast cancers in BRCA1 mutation carriers are estrogen receptor negative (ER-) with a basal-like phenotype, up to one third are ER positive (ER+). Little is known about the characteristics of this subgroup. To address this, we compared histologic and immunophenotypic features of 60 BRCA1-related ER+ breast cancers with those of 85 BRCA1-related ER- cancers and 174 matched ER+ sporadic cancers. ER+ BRCA1-related cancers were significantly less likely than ER- BRCA1-related cancers to be of pure invasive ductal type (P<0...

Mucosa-associated lymphoid tissue (MALT) lymphoma is thought to be a multifocal disease with sometimes synchronous involvement of various mucosal structures. In this study we aimed to evaluate the potential involvement of the small bowel in patients suffering from gastric MALT lymphoma by analyzing the results of enteroscopy, a technique that allows easy and safe access to the small bowel with the potential for histological assessment of biopsy samples. We have retrospectively evaluated 347 enteroscopies and found nine patients with gastric MALT lymphoma who had undergone push enteroscopy with serial biopsies during staging...

BACKGROUND: Complete tumor resection is the mainstay of treatment for retroperitoneal sarcoma (RPS), but the size and quality of surgical margins for radical resection in RPS are unknown. They are believed to be pushing tumors, but recently, aggressive surgical policies leading to multivisceral resection have seemed to suggest better local control compared with simple tumor resection. We analyzed a single-institution series of RPS to provide information useful to surgical decision-making...

Pioneering clinical studies in de novo refractoriness to the anti-HER2 monoclonal antibody trastuzumab have suggested that HER2 gene-amplification can take place also in a basal-like molecular background to generate basal/HER2+ tumors intrinsically resistant to trastuzumab. Here, we first investigated the unique histogenesis of the basal/HER2+ phenotype in breast carcinomas. The presence of basal CK5/CK6 cytokeratin expression in HER2+ tumors revealed a significant overlap in the histological features of HER2+/CK5/6+ and basal-like breast carcinomas...

INTRODUCTION: Most breast cancers that occur in women with germline BRCA1 mutations are estrogen receptor-negative (ER-) and also typically lack expression of progesterone receptor (PR) and HER2 overexpression. We undertook a study to assess the clinical factors that predict for an estrogen receptor positive (ER+) breast cancer in BRCA1 mutation carriers and to characterize the pathologic features of these tumors. METHODS: Clinical characteristics of BRCA1 carriers with 58 ER+ and 114 ER- first invasive breast cancers were compared...
