RESUMEN

The concomitant presence of breast cancer with one or more other types of cancer such as colon, vulva, lung, larynx, liver, uterus and kidneys has been presented in the literature. However, synchronous breast and renal cancer is very uncommon. Herein we present a woman with synchronous breast and renal cancer, and review the literature. A 77-year-old post-menopausal woman was admitted to our clinic complaining of left sided breast mass. On physical examination, there was a 3 cm palpable mass in the upper outer quadrant of the left breast along with a conglomerate of lymph nodes in the left axilla. Ultrasonography and mammography showed a 3 cm solid, hypoechoic mass in the upper outer quadrant and left axillary lymphadenopathy. The tru-cut biopsy of the lesion revealed invasive ductal carcinoma. The bone scintigraphy, thoracic and cranial computerized tomographies were normal. The abdominal computerized tomography identified a 3×3 cm solid renal mass with heterogeneous contrast enhancement in the posterior segment of the lower pole, which was suspicious for renal cell carcinoma. Breast conserving surgery and axillary lymph node dissection was performed, and the pathology specimen demonstrated invasive ductal carcinoma. The patient was discharged on postoperative day 5. Three weeks later partial nephrectomy was performed by urology department for the solid renal mass, and the pathology result showed clear cell-renal carcinoma with Fuhrman grade 3. The patient is being followed-up for renal carcinoma, and underwent radiotherapy for breast cancer. Hormonotherapy for breast cancer is still continuing.

RESUMEN

BACKGROUND: Breast cancer is the most common cancer type among women with increasing incidence rates, improved prognosis and survival. According to the localization of the tumor, breast cancer is designated as unilateral (UBC) or bilateral (BBC). BBC can be classified as synchronous (SBBC) or metachronous (MBBC) based on the time interval between the diagnosis of the first and the secondary tumors. According to the guideline of WHO 2012, BBC is generally defined as SBBC when contralateral breast carcinoma is diagnosed within 3 months. The aim of this study was to compare the characteristics and patterns of metastasis of BBC patients with UBC. MATERIALS AND METHODS: A cohort of 768 patients with breast cancer treated at the Turkish Ministry of Health-Izmir Bozyaka Research and Training Hospital between 1976 and 2012 were studied. Survival analysis was performed comparing UBC and BBC patients. In addition, evaluations were performed in patients with SBBC and MBBC sub-groups. We used a 3-months interval to distinguish metachronous from synchronous. RESULTS: When clinical and histopathological parameters were statistically evaluated, ER status, event-free and overall survival were found to be significant between UBC and BBC patients. In comparison of SBBC and MBBC patients, age, histological type of tumor, event-free and overall survival were found to be significant. CONCLUSIONS: BBC cases were found to show worse prognosis than UBC cases. Among BBC, SBBC had the worst prognosis based on overall survival rates.

RESUMEN

BACKGROUND: In this retrospective analysis, the clinicopathological features and pattern of metastatic spread of invasive ductal carcinoma (IDC), invasive lobular carcinoma (ILC), and mixed ductal/lobular carcinoma (MDLC), together with the type and outcome of surgical intervention, were comparatively evaluated. METHODS: A total of 633 breast cancer patients with histopathological subtype IDC, ILC or MDLC were included in the study. The mean age was 52.6 ± 12.7 years. Follow-up period ranged between 0 and 33 (median 6.0) years. The groups were compared with respect to age, tumor size, nodal involvement, stage, hormonal therapy, multicentricity, multifocality, bilaterality, estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2)/neu, p53, and Ki67 expression, disease-free survival (DFS) and overall survival (OS) rates, and surgical approach. RESULTS: The distribution of patients was as follows: IDC 508 (80.3 %), ILC 78 (12.3 %), MDLC 47 (7.4 %). Among the parameters evaluated, statistically significant differences were observed in mean tumor size (IDC 2.5 ± 1.98 cm, ILC 3.0 ± 1.8 cm, MDLC 3.2 ± 2.4 cm), advanced T stage (T3 + T4) at diagnosis (IDC 14.7 %, ILC 21.4 %, MDLC 25.6 %), N stage (N0 was dominant in IDC and ILC; N3 was dominant in MDLC), tumor-node-metastasis (TNM) stage (stage II was dominant in IDC and ILC; stage III was dominant in MDLC), HER2/neu expression (IDC 23.8 %, ILC 11.8 %, MDLC 21.4 %), and frequency of bone metastasis (IDC 14.3 %, ILC 17.9 %, MDLC 25.5 %). CONCLUSIONS: MDLC-type tumors have different histopathological characteristics and are often diagnosed at advanced stage. However, their survival outcomes do not vary significantly from ILC and IDC.

RESUMEN

Primary small cell carcinoma of the urinary bladder is very rare. A 72-year-old was admitted to our hospital because of hematuria and dysuria. Cystoscopy revealed a bladder full of multiple, solid and papillary tumors. Biopsies from the deep and papillary tumors were taken. Histologically, tumor was pure small cell carcinoma. Immunohistochemically, the tumor cells were positive for cytokeratin, chromo-granin, synaptophysin, neuron-specific enolase, CD56, CD117 and Ki67 (labeling 70%). The tumor cells were negative for CK7, CK20, CD3, CD20, LCA, CDX2, uroplakin, thyroid transcription factor 1, PSA and p63. Metastatic workup was performed an no primary or metastatic lung lesions were noted. Due to the clinical, radiologic and immunohistochemical findings, the patient was diagnosed as primary small cell carcinoma of bladder. A molecular genetic analysis for KIT (exons 9, 11, 13 and 17) and PDGFRA (exons 12 and 18) genes was performed, in paraffin micro dissection specimens, by the PCR-direct sequencing method. According to the sequencing analyses, two mutations were found at positions 558 (p.K558N) and 562 (p.E562D) in KIT gene exon 11 in our case. The another hand the same case presented two mutations in PDGFRA gene exon 14 at position 631 (p.P631A) and 638 (p.638Q_639AinsC). The disease process was fulminant and the patient was lost due to several complications prior to any chemotherapy.

RESUMEN

BACKGROUND: Solid pseudopapillary neoplasia (SPN) of the pancreas is an extremely rare epithelial tumor of low malignant potential. SPN accounts for less than 1% to 2% of exocrine pancreatic tumors. The aim of this study is to report our experience with SPN of the pancreas. It includes a summary of the current literature to provide a reference for the management of this rare clinical entity. METHODS: A retrospective analysis was performed of all patients diagnosed and treated for SPN in our hospital over the past 15 years (1998 to 2013). A database of the characteristics of these patients was developed, including age, gender, tumor location and size, treatment, and histopathological and immunohistochemical features. RESULTS: During this time period, 255 patients with pancreatic malignancy (which does not include ampulla vateri, distal choledocal and duodenal tumor) were admitted to our department, only 10 of whom were diagnosed as having SPN (2.5%). Nine patients were women (90%) and one patient was a man (10%). Their median age was 38.8 years (range 18 to 71). The most common symptoms were abdominal pain and dullness. Seven patients (70%) presented with abdominal pain or abdominal dullness and three patient (30%) were asymptomatic with the diagnosis made by an incidental finding on routine examination. Abdominal computed tomography and/or magnetic resonance imaging showed the typical features of solid pseudopapillary neoplasm in six (60%) of the patients. Four patients underwent distal pancreatectomy with splenectomy, one patient underwent a total mass excision, and one patient underwent total pancreatic resection. Two required extended distal pancreatectomy with splenectomy. Two underwent spleen-preserving distal pancreatectomy. CONCLUSIONS: SPN is a rare neoplasm that primarily affects young women. The prognosis is favorable even in the presence of distant metastasis. Although surgical resection is generally curative, a close follow-up is advised in order to diagnose a local recurrence or distant metastasis and choose the proper therapeutic option for the patient.

RESUMEN

AIMS AND BACKGROUND: Sentinel lymph node biopsy has been accepted as a standard procedure for early stage breast cancer. In this retrospective analysis, the results obtained with different methodological approaches using radiocolloid with or without blue dye were examined. METHODS: A total of 158 sentinel lymph node biopsies were performed in 152 patients. Group A (85 patients) underwent lymphatic mapping using a combination of periareolar intradermal radiocolloid and subareolar blue dye injections. Group B (73 patients) underwent only periareolar intradermal radiocolloid injection. One large tin colloid and two small radiocolloids (nanocolloid of serum albumin -NC- and colloidal rhenium sulphide -CS-) were used. RESULTS: Successful lymphatic mapping was attained in 157 of 158 procedures (99.4%). Radiocolloids localized sentinel lymph nodes in 99.4% and blue dye in 75.3% of the cases. The number of sentinel lymph nodes removed was greater in nanocolloid and colloidal rhenium sulphide groups (P ≤0.05). Among 60 metastatic sentinel lymph nodes, frozen section analysis using hematoxylin and eosin staining failed to detect 1 macro- and 10 micrometastasis. Radiocolloid uptake was higher in sentinel lymph nodes accumulating blue dye (1643 ± 3216 counts/10 sec vs 526 ± 1284 counts/10 sec, P <0.001). Higher count rates were obtained by using larger sized colloids (median and interquartile range: tin colloid, 2050 and 4548; nanocolloid, 835 and 1799; colloidal rhenium sulphide, 996 and 2079; P = 0.01). Only 2 extra-axillary sentinel lymph nodes were visualized using periareolar intradermal injection modality. CONCLUSIONS: Radiocolloids were more successful than blue dye in sentinel lymph node detection. More sentinel lymph nodes were harvested with small colloids, but different sized radiocolloids were similarly successful. Sentinel lymph nodes having higher radiocolloid uptake tended to accumulate blue dye more frequently. Sentinel lymph nodes manifested higher count rates when a larger colloid was used. Frozen section was very successful in detecting macrometastatic disease in sentinel lymph nodes, but the technique failed in most of the micrometastates.

RESUMEN

BACKGROUND: Sentinel lymph node biopsy is a standard method for the evaluation of axillary status in patients with T1-2N0M0 breast cancers. AIMS: To determine the prognostic significance of primary tumour-related clinico-histopathological factors on axillary and non-sentinel lymph node involvement of patients who underwent sentinel lymph node biopsy. STUDY DESIGN: Retrospective clinical study. METHODS: In the present study, 157 sentinel lymph node biopsies were performed in 151 consecutive patients with early stage breast cancer between June 2008 and December 2011. RESULTS: Successful lymphatic mapping was obtained in 157 of 158 procedures (99.4%). The incidence of larger tumour size (2.543±1.21 vs. 1.974±1.04), lymphatic vessel invasion (70.6% vs. 29.4%), blood vessel invasion (84.2% vs. 15.8%), and invasive lobular carcinoma subtype (72.7% vs. 27.3%) were statistically significantly higher in patients with positive SLNs. Logistic stepwise regression analysis disclosed tumour size (odds ratio: 1.51, p=0.0021) and lymphatic vessel invasion (odds ratio: 4.68, p=0.001) as significant primary tumour-related prognostic determinants of SLN metastasis. CONCLUSION: A close relationship was identified between tumour size and lymphatic vessel invasion of the primary tumour and axillary lymph node involvement. However, the positive predictive value of these two independent variables is low and there is no compelling evidence to recommend their use in routine clinical practice.

RESUMEN

Warthin's tumor is the second most common type of salivary gland tumor. Microscopically, Warthin's tumor displays a proliferative epithelial component and lymphoid stroma. Carcinomas arising from the epithelial component are well known, but malignant transformations of the lymphoid stroma are rare. When they do occur, they are most commonly B-cell type non-Hodgkin lymphomas. A 60-year-old male patient underwent surgical resection of a parotid mass. After superficial parotidectomy, microscopic examination indicated that the tumor was of epithelial components with basaloid and oncocytic columns of cells neighboring lymphoid components. In addition to the lymphoid follicles with distinct germinal centers, there were large, bizarre and extremely atypical neoplastic cells seen in the lymphoid component. Large neoplastic cells were diffusely CD20 and CD30 positive. The patient was diagnosed with "Warthin's tumor and diffuse large B-cell lymphoma with expression of CD30." The histopathologic and clinical features are discussed along with a review of the literature.

RESUMEN

OBJECTIVES: Tumor heterogeneity is a common finding and led to realization of a tertiary Gleason component (TGC) in prostate cancer. In an attempt to further investigate its prognostic value, we analyzed the association of tertiary Gleason pattern in Gleason score ≤ 7 tumors with pathologic stage and biochemical disease-free survival. MATERIAL AND METHODS: A total of 331 radical prostatectomy specimens were analyzed retrospectively. The primary, secondary, and the tertiary patterns were evaluated by reviewing all of the pathologic slides. TGC was defined as Gleason grade pattern 4 or 5 for Gleason score < 7 tumors and Gleason grade pattern 5 for Gleason score 7 tumors. The pathologic prognostic factors, (extraprostatic extension, seminal vesicle and lymph node invasion, surgical margin status) of Gleason score < 7, 3+4, and 4+3 tumors with or without TGC were compared. Biochemical recurrence-free survival (BRFS) was calculated using Kaplan-Meier method with log rank test, and the influence of TGC was assessed in a Cox regression model. RESULTS: TGC observed more frequently with higher Gleason scores (21% of the GS < 7 cases, 23% of the GS 3+4 cases, and 58% of the GS 4+3 cases). In terms of adverse pathologic prognostic factors and BRFS, GS < 7 tumors with TGC behaved significantly worse than GS < 7 tumors without TGC (P = 0.01 and P = 0.001, respectively) with properties similar to GS 3+4 tumors without TGC. Gleason score 3+4 and 4+3 tumors without TGC were statistically similar and had better features than corresponding tumors of same Gleason score with TGC. Furthermore, Gleason score 7 tumors with TGC had similar features with GS 8-10 tumors. During follow-up, 73 (22%) subjects had PSA recurrence. In the Cox regression model TGC was an independent variable for BRFS (HR = 2.63, 95% CI = 1.39-4.98, P = 0.003). CONCLUSION: According to the present study, 3 different prognostic groups were observed; good prognostic group: GS < 7, intermediate prognostic group: GS < 7+TGC, GS 3+4, and GS 4+3, and finally bad prognostic group: GS (3+4)+TGC, GS (4+3)+TGC, GS > 7. Presence of a TGC appears to upgrade the total score and adjuvant treatment decisions may further be refined by considering the tertiary pattern.

RESUMEN

AIMS: The primary objective of this study was to clarify the influence of histotype on the outcome of D1/D2 gastrectomized patients with pathologically proven R0 resection. The secondary objective was to demonstrate overall survival (OS), disease-free survival (DFS), and locoregional recurrence rates following standard curative surgery. PATIENTS AND METHODS: All patients had either pure signet-ring cell carcinoma (SRCC)/poorly differentiated adenocarcinoma (PDC) or moderately differentiated adenocarcinoma (MDC) of the stomach, preoperative radiologic evidence of locoregional disease, and no history of neoadjuvant therapy. Standards of surgical treatment were essentially based on the guidelines of the Japanese Research Society for the Study of Gastric Cancer. RESULTS: Between October 2003 and August 2010, seventy-eight patients were enrolled. Twenty-three patients underwent D1 dissection and 55 underwent D2 dissection. The OS and DFS rates were 33.2 ± 5.9 months versus 31.5 ± 4.3 months (p = 0.81) and 28.9 ± 5.6 months vs. 29.3 ± 4.4 months (p = 0.96) in the MDC and SRCC/PDC groups, respectively. Neither the extent of the operation (D1 vs. D2, p = 0.79) nor the histopathologic subtype of the primary tumor (MDC vs. SRCC/PDC, p = 0.91) influenced the OS and DFS. Multivariate logistic regression analysis disclosed pathologic stage (pTNM) as the only significant prognostic determinant of OS (p = 0.007) and DFS (p = 0.0003). CONCLUSION: Properly performed D1 and D2 dissection in our series resulted in a notable (6.4%) locoregional failure rate. In spite of the satisfactory locoregional control achieved by D1 and D2, there was no improvement in the survival figures of stage IIIA-B and IV gastric cancer patients. The histopathologic subtype of the primary tumor disclosed merely a statistical trend on the outcome measures of gastric cancer after curative surgery.

RESUMEN

Pseudoangiomatous stromal hyperplasia is a benign proliferative lesion of the mammary stroma that rarely presents as a localized mass. Pseudoangiomatous stromal hyperplasia is characterized by a dense, collagenous proliferation of the mammary stroma, associated with capillary-like spaces. Pseudoangiomatous stromal hyperplasia can be mistaken with fibroadenoma on radiological examination or with low-grade angiosarcoma on histological examination. Its main importance is its distinction from angiosarcoma. The presented case was a 40-year-old woman who was admitted with a rapidly growing breast tumor. Physical examination revealed an elastic-firm, well-defined, mobile and painless mass in her right breast. Mammograms revealed a 6.7 x 3.7 cm, lobulated, well-circumscribed mass in her right breast but no calcification. Sonographic examination showed a well-defined and homogenous mass, not including any cyst. Based on these findings, a provisional diagnosis of fibroadenoma was made. Considering the rapid growth history of the mass, tumor excision was performed. The excised tumor was well demarcated and had a smooth external surface. Histological examination revealed the tumor to be composed of markedly increased fibrous stroma and scattered epithelial components (cystic dilatation of the ducts, blunt duct adenosis). The fibrous stroma contained numerous anastomosing slit-like spaces. Isolated spindle cells appeared intermittently at the margins of the spaces resembled endothelial cells. Immunohistochemical staining showed that the spindle cells were positive for CD34 and negative for Factor VIII-related antigen. The lesion was diagnosed as nodular pseudoangiomatous stromal hyperplasia.

RESUMEN

OBJECTIVE: A prospective study in 82 consecutive patients with mid- and distal rectal adenocarcinomas having specific histology and tumor stage was conducted to asses impact of curative surgery. METHODS: Patients with moderately differentiated adenocarcinoma (MDAC) with or without mucinous differentiation underwent curative resection. Forty patients were in Stage B1-B2 and 42 patients were in Stage C1-C2. Surgery options were: (1) Abdominoperineal resection (APR) for tumors located within 6cm of the anal verge and (2) Tumor specific mesorectal excision (TSME) and low anterior anastomosis (LAA) for those located between 6 to 12cm from the anal verge. The primary endpoints were overall (OS) and disease-free survival (DFS). RESULTS: Patients in Stage B1-B2 had a local failure rate of 15% compared with 31% of patients in stage C1-C2 (p=0.18). Satellite tumor nodule formation (STN) was observed in one patient in B group and in 13/42 (31%) of Stage C tumors. LR did not vary with mucinous differentiation. Only lymph node involvement (N1-3) (p=0.028) had an impact on locoregional recurrence and both lymph node involvement and STN formation influenced disease-free survival (p=0.008). CONCLUSION: Preoperative precise detection of Stage C rectal adenocarcinomas is of utmost importance to facilitate the implementation of therapies for downstaging and for better local and distant control following surgery.

RESUMEN

INTRODUCTION: Cholemia and bacterial translocation with portal endotoxemia are integral in the pathogenesis of obstructive jaundice (OJ). There is sufficient experimental data about hemodynamic and histopathological consequences of OJ. In contrast, pathological information of renal changes in patients with OJ is still lacking. Therefore; the primary objective of this prospective study is to show the specific histopathological changes in kidneys of patients with short-term biliary tract obstruction receiving a standard perioperative medical treatment protocol. MATERIALS AND METHODS: Twenty consecutive patients with biliary obstruction were included in the study. Fluid replacement, prevention of biliary sepsis, and portal endotoxemia were mainstays of the perioperative treatment protocol. Fluid and electrolyte balance was maintained by twice daily body weight calculations, central venous pressure, and mean arterial pressure monitoring. Renal function was assessed by glomerular filtration rate estimation by modification of diet in renal disease-7 formula. Kidney biopsy evaluation was focused on tubular changes, thrombotic microangiopathy, endothelial damage, and peritubular capillary (PTC) dilatation with or without C4d staining. Fresh frozen sections were evaluated with immunofluorescence microscopy for glomerular IgG, IgA, IgM, C3, and C1q staining. RESULTS: The mean duration of OJ was 15.5 ± 1.4 days. Body weight increased before surgery through volume expansion (P = 0.001). All patients have shown mean arterial pressure ≥ 70 and ≤ 120 mmHg and renal function was very well preserved in all but one subject during the perioperative period. Despite those favorable figures, dilatation of peritubular venules and acute tubular necrosis were shown synchronously in all cases. C4d staining in PTC and arterioles and thrombotic microangiopathy were entirely absent in the study group. Immune complex deposits in PTCs and in glomeruli were not detected. Three patients had isolated glomerular C4d deposition without accompanying thrombotic microangiopathy and IgG, IgA, IgM, C3, and C1q staining of glomerular capillaries in I immunofluorescence microscopy. DISCUSSION: This study is the first in the literature to address the histopathological changes that occur in humans with short-term biliary obstruction. Acute tubular necrosis and venous dilatation was observed in all biopsies, without exception, despite the maintenance of strict volume control in all patients. The adequacy of volume control may not be implicated in those results; rather a possible mechanism related to untrapped endotoxin in the gut lumen or systemic circulation might lead to prolonged PTC dilatation and hypoperfusion with synchronous acute tubular necrosis. Absolute recovery of renal function in all patients and the demonstration of solitary acute tubular necrosis with no microvascular-glomerular-interstitial inflammation or injury, suggests that the perioperative treatment regime in this study is fairly efficacious in short-term OJ.

RESUMEN

The purpose of the study was to describe the imaging findings of male breast disease. One hundred and sixty-four male patients, who underwent mammography and ultrasonography (US) between January 1999 and December 2008, were retrospectively evaluated. Seventy-five patients (46%) underwent biopsy, and 89 patients (54%) were diagnosed radiologically. The radiologic and pathologic diagnoses in 164 cases of this series were 13 cancers (8%), including one ipsilateral and one contralateral breast cancers, 147 cases of gynecomastia (90%), one fibroadenoma (0.6%), two cases of fibrocystic disease of the breast (1.2%), and one epidermoid inclusion cyst (0.6%). Three mammographic patterns were adequate to describe all 147 cases of gynecomastia in our series: 53 patients (36%) had nodular gynecomastia, 46 patients (31%) had dendritic gynecomastia, and 48 patients (33%) had diffuse gynecomastia. Gynecomastia was unilateral in 65% of cases (n=95), and bilateral in 35% of cases (n=52). On physical examination, two of the malignant lesions had no clinic features of malignancy (15%). On mammography, 11 of 13 malignant masses were demonstrated (85%). A mass with microcalcifications was seen on mammograms in one case (9%). The contours of the masses were irregular in nine cases (82%), well-circumscribed in two cases (18%). The location of the masses was retroareolar in seven cases (64%) and eccentric to the nipple in four cases (36%). The size of the masses varied between 0.5 cm and 5 cm (mean 2.4 cm). Nipple retraction was evident in five cases (45%), and skin thickening in four cases (36%). All of the malignant masses were demonstrated on ultrasound; however, one of them was seen retrospectively after mammography. All of the masses were hypoechoic and solid, the contours were well-defined and smooth in two masses (15%), and irregular in 11 masses (85%), and five masses (39%) had posterior prominent shadowing. Axillary lymphadenopathia was detected in two cases (15%). One patient had a previous contralateral breast cancer, and one had an ipsilateral. On mammography, breast cancer characteristically exhibits an irregular subareolar mass, nipple retraction, and skin ulceration or thickening, but sometimes breast cancer has a well-circumscribed contour and punctuated microcalcifications. Ultrasonography is essential and useful for further characterization and helpful for demonstrating lymphadenopathies of the axillary region.

RESUMEN

OBJECTIVE: To present a case of small bowel perforation due to metastatic lung cancer. CASE PRESENTATION AND INTERVENTION: A 78-year-old male patient, who had been diagnosed with lung cancer 3 months earlier, presented to our clinic with acute abdominal pain. He underwent emergency laparotomy. At surgery, there was a circumferential lesion encompassing the ileum with complete transection. There was no obvious macroscopic appearance of metastatic disease. The involved bowel segment was resected and an ileostomy was performed. Postoperative pathologic analysis confirmed metastatic squamous cell carcinoma metastasis to the ileum, arising from the patient's lung cancer. CONCLUSION: This case report showed that small bowel metastases should always be considered in the differential diagnosis of lung cancer patients presenting with acute abdominal pain.

RESUMEN

UNLABELLED: Carcinosarcoma of the breast, also known as metaplastic carcinoma, is rare with very few cases reported in the literature. A 46-year old female patient presented with a mass in her left breast. Physical examination, ultrasonography and mammography findings were consistent with malignancy. The mass was totally removed. Histopathological examination revealed carcinosarcoma of the breast. Histologic grade of the tumour was III. Ki67 proliferation index was found 40% positive. Tumour cells were positive for p53 (70% positive), c-erb-B2 (5% positive), pancytokeratin and EMA in carcinomatous areas, and vimentin in sarcomatous areas. There was no metastasis in axillary lymph node and distant metastasis. The patient is receiving chemotherapy and is under follow-up in the 54th month. Along with a review of the literature, we present the information regarding the clinical and histological findings and treatment of the patient who was operated due to breast carcinosarcoma. KEYWORDS: Breast; Carcinoma; Carcinosarcoma.

RESUMEN

Gastrointestinal stromal tumors (GISTs) are rare neoplasms of the gastrointestinal tract. One to three percent of GISTs occur in the esophagus. GISTs have a great potential for diffuse intra- abdominal spread and liver metastasis, which are the two most common modes of dissemination. Metastases to other sites, especially the bones and lung, are relatively rare. Never has an esophageal GIST been documented to present with pulmonary and bone metastases. We present an unusual case of an esophageal GIST with pulmonary and bone lesions. We include a review of the literature.

RESUMEN

BACKGROUND/AIMS: Non-invasive serum markers are being used to determine fibrosis score as an alternative to liver biopsy. The aim of the present study was to evaluate the accuracy and predictive value of the non-invasive markers in identifying the presence or absence of significant fibrosis in patients with chronic viral hepatitis. METHODOLOGY: A total of 557 patients (401 chronic hepatitis B (CHB), 156 chronic hepatitis C (CHC)) were enrolled into the study retrospectively. Liver biopsies were evaluated histopathologically according to the Knodell scoring system. Laboratory values such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), y-glutamyltranspeptidase (GGT) and platelet count (PLT) was tested on the same day of liver biopsy. Using these laboratory values, AST/ALT ratio (AAR), age-platelet index (API) and AST/ PLT ratio index (APRI), GGT/PLT ratio index (GAPI) and AST to GGT ratio (AGR) were calculated. RESULTS: Advanced liver fibrosis including stage 3-4 was observed in 197 (49%) of patients with CHB, 84 (54%) of patients with CHC. Mean age and GGT were higher and PLT was lower in patients with advanced liver fibrosis (stage 3-4) than those in patients with absence of significant fibrosis (stage 0-1) (p < 0.001). But, there was no statistically significant relationship for mean value of AST and ALT between patients with stage 0-1 and stage 3-4. The API and GAPI were found to be significantly associated with the fibrosis score and correlation co-efficient (r) were 0.35 and 0.23, respectively (p < 0.001), while the APRI, AAR and AGR values were not associated with the fibrosis score in all of the patients (p > 0.05). But, APRI has showed correlation with liver fibrosis in patients with CHC contrary to patients with CHB. CONCLUSION: Age, GGT, PLT, API and GAPI are significantly associated with the extent of fibrosis. But these non-invasive markers can not replace liver biopsy.
