    2009-01-01

    Introduction Invasive ductal and lobular carcinomas represent 67.9% and 6.3% of breast carcinoma, respectively. Metastatic breast cancer typically involves the lungs, bones, brain, and liver. Studies have shown differing patterns of metastatic spread between ductal and lobular carcinoma. Lobular carcinoma is more likely to metastasise to the gastrointestinal tract. Case presentation We report the case of a 49 year old white woman with invasive ductal carcinoma with lobular differentiation who...

    A case of ductal carcinoma of the parotid gland is described. The medical literature contains only 13 previous reports on this kind of adenocarcinoma of the parotid gland. The tumour is characterized by its histologic resemblance to ductal carcinomas of the breast and prostate. The course of previously described cases suggests that this tumour has a highly aggressive biological behaviour.

  3. Invasive Ductal Carcinoma Arising in Phyllodes Tumor With Isolated Tumor Cells in Sentinel Lymph Node

    Full Text Available Phyllodes tumor (PT consists of stroma of variable grading and benign ductal epithelium. Although exceptional, carcinomas that arise from the epithelium in PTs do exist, and seem to behave less aggressively than the usually encountered breast carcinoma. To the best of our knowledge, among the invasive carcinomas that have arisen in PTs, only 1 has been proved to have metastatic carcinoma in the lymph nodes. Here, we describe the youngest woman to have invasive ductal carcinoma that arose in a borderline PT, with isolated carcinoma cells in the sentinel lymph node. Whether such a combined lesion carries a more indolent course is also discussed.

    Full Text Available Abstract Background To date, the clinical presentation and prognosis of mixed ductal/lobular mammary carcinomas has not been well studied, and little is known about the outcome of this entity. Thus, best management practices remain undetermined due to a dearth of knowledge on this topic. Methods In this paper, we present a clinicopathologic analysis of patients at our institution with this entity and compare them to age-matched controls with purely invasive ductal carcinoma (IDC and historical data from patients with purely lobular carcinoma and also stain-available tumor specimens for E-cadherin. We have obtained 100 cases of ductal and 50 cases of mixed ductal/lobular breast carcinoma. Results Clinically, the behavior of mixed ductal/lobular tumors seemed to demonstrate some important differences from their ductal counterparts, particularly a lower rate of metastatic spread but with a much higher rate of second primary breast cancers. Conclusions Our data suggests that mixed ductal/lobular carcinomas are a distinct clinicopathologic entity incorporating some features of both lobular and ductal carcinomas and representing a pleomorphic variant of IDC.

    Invasive lobular carcinoma of the breast has similar patterns of metastatic disease when compared to invasive ductal carcinoma; however, lobular carcinoma metastasizes to unusual sites more frequently. We present a 65-year-old female with a history of invasive lobular breast carcinoma (T3N3M0) treated with modified radical mastectomy and aromatase-inhibitor therapy who underwent a surveillance PET scan, which showed possible sigmoid cancer. Colonoscopy with biopsy revealed a 3?cm sigmoid aden...

    Ductal carcinoma in situ (DCIS) is a noninvasive malignant breast disease traditionally described as a precursor lesion to invasive breast cancer. With screening mammography, DCIS now accounts for approximately 20% of newly diagnosed cancer cases. DCIS is not well understood because of its heterogeneous nature. Studies have aimed to assess prognostic factors to characterize its risk of invasive potential; however, there still remains a lack of uniformity in workup and treatment. We summarize current knowledge of DCIS and the ongoing controversies.

    2012-01-01

    Full Text Available Ductal carcinoma in situ (DCIS of the breast represents a complex, heterogeneous pathologic condition in which malignant epithelial cells are confined within the ducts of the breast without evidence of invasion. The increased use of screening mammography has led to a significant shift in the diagnosis of DCIS, accounting for approximately 27% of all newly diagnosed cases of breast cancer in 2011, with an overall increase in incidence. As the incidence of DCIS increases, the treatment options continue to evolve. Consistent pathologic evaluation is crucial in optimizing treatment recommendations. Surgical treatment options include breast-conserving surgery (BCS and mastectomy. Postoperative radiation therapy in combination with breast-conserving surgery is considered the standard of care with demonstrated decrease in local recurrence with the addition of radiation therapy. The role of endocrine therapy is currently being evaluated. The optimization of diagnostic imaging, treatment with regard to pathological risk assessment, and the role of partial breast irradiation continue to evolve.

    Full Text Available Malignant tumors of the oral cavity which are metastatic are very rare and consist of 1% of malignancies of the oral cavity. Numbness or paresthesia of the lower lip or the chin is the main feature of presence of metastasis in the jaw. Our patient was a 38 year old woman with chief complaint of pain in the right half of her face, jaw and teeth. Her medical history revealed a radical mastectomy with lymphadenectomy in the left breast because of invasive ductal carcinoma grade II/III and stage IIIA (T2N2M0 without distant metastasis, followed by chemotherapy (before and after the surgery and radiotherapy two years ago. Following complementary examinations a malignant bone lesion in particular osteosarcoma was suspected. According to this evidence, possibility of early diagnosis of malignant tumors is very important for dentists and maxillofacial surgeons. Symptoms such as paresthesia of the lip and chin is very helpful in differential diagnosis of metastatic lesions from other similar clinical cases especially in patients with history of malignancies which minimize surgical and mental injuries and increase life expectancy of patients.

    Full Text Available We present the diagnostic inaccuracies encountered in a case of multiple fibroadenoma with malignant transformation. A 30-year-old lady presented with lump in the right breast of one month duration which on clinical examination, X-ray mammogram, sonomammogram were suggestive of multiple fibroadenomas. Fine needle aspiration cytology of the largest lump revealed features of malignancy and a core biopsy showed pleomorphic cells that could not be categorized. Due to the clinical, radiological and pathological diagnostic ambiguity, lumpectomy was performed and frozen section showed features of only conventional fibroadenoma. Representative bits on routine processing showed only features of fibroadenoma. Hence, complete submission of all lumps was done, which revealed fibroadenoma with invasive ductal carcinoma in one. Patient underwent modified radical mastectomy which showed multiple fibroadenomas, focal fibrocystic disease with a focus of residual invasive tumor and metastatic deposit in one axillary lymph node. This case report highlights the diagnostic challenges in detecting malignancy in fibroadenoma and a need for extensive tissue sampling in multiple fibroadenomas to detect the rare occurrence of carcinoma.

  12. Ductal carcinoma in situ: a challenging disease

    Full Text Available Ductal carcinoma in situ (DCIS represents a heterogenous group of lesions with variable malignant potential. Although it is clearly pre-invasive, not all lesions progress to an invasive malignant disease. The significant increase in the frequency of diagnosis is the result of both widespread use of screening mammography and better recognition among pathologists. Treatment is controversial, but for several decades total mastectomy has been considered as the appropriate treatment. The tendency to be less aggressive in terms of surgery has followed the pattern of events observed in the treatment of invasive breast carcinomas. More recently, it has become clear that breastconserving procedures could be applied and selected on the basis of diagnostics and risk factors. When all patients with DCIS are considered, the overall mortality is extremely low, only about 1–2%. On the other hand, breast-conserving surgery is only curative in 75–85%; 50% of the local recurrences have proven to be invasive with a mortality rate of 12–15%. There is no place for axillary node dissection, adjuvant hormonal treatment or chemotherapy in the treatment. Important factors in predicting local recurrence are age, family history, nuclear grade, comedo-type necrosis, tumor size and margin width. With the addition of radiation therapy to excisional surgery, there is a 50% reduction in the overall local recurrence rate. The Van Nuys Prognostic Index (VNPI, recently updated, is a tool that quantifies measurable prognostic factors that can be used in the decision-making process of treatment. Recent data from large cohort studies and randomized trials have emerged to guide treatment. DCIS is now understood to have diverse malignant potential and it is unlikely that there will be a single treatment for this wide range of lesions. Advances in molecular biology and gene expression profiling of human breast tumors have been providing important insights into the relationship

  13. Metastatic renal cell carcinoma management

    2009-06-01

    Full Text Available PURPOSE: To assess the current treatment of metastatic renal cell carcinoma, focusing on medical treatment options. MATERIAL AND METHODS: The most important recent publications have been selected after a literature search employing PubMed using the search terms: advanced and metastatic renal cell carcinoma, anti-angiogenesis drugs and systemic therapy; also significant meeting abstracts were consulted. RESULTS: Progress in understanding the molecular basis of renal cell carcinoma, especially related to genetics and angiogenesis, has been achieved mainly through of the study of von Hippel-Lindau disease. A great variety of active agents have been developed and tested in metastatic renal cell carcinoma (mRCC patients. New specific molecular therapies in metastatic disease are discussed. Sunitinib, Sorafenib and Bevacizumab increase the progression-free survival when compared to therapy with cytokines. Temsirolimus increases overall survival in high-risk patients. Growth factors and regulatory enzymes, such as carbonic anhydrase IX may be targets for future therapies. CONCLUSIONS: A broader knowledge of clear cell carcinoma molecular biology has permitted the beginning of a new era in mRCC therapy. Benefits of these novel agents in terms of progression-free and overall survival have been observed in patients with mRCC, and, in many cases, have become the standard of care. Sunitinib is now considered the new reference first-line treatment for mRCC. Despite all the progress in recent years, complete responses are still very rare. Currently, many important issues regarding the use of these agents in the management of metastatic renal cancer still need to be properly addressed.

    The purpose of this study is to evaluate mammographic findings of invasive ductal carcinoma (IDC) and invasive lobular carcinoma(ILC) and to find differential points between the two. 239 patients, who underwent mammography prior to surgery and were proved to have IDC(patients) or ILC(15 patients) pathologically, were analized retrospectively. On mammogram, presence of mass and microcalcification were analized. When there was a mass on mammogram, lesion opacity was classified into high, equal, or low opacity and border of the mass was classified into spiculated, poorly marginated, and well-marginated. When there was no definite mass, mammographic findings were classifie into asymmetric opacity and no mass. Masses were observed in 168 patients(75%) of IDC and 12 patients(80%) of ILC. Border of the masses were spiculated(n=50, 22.3%), poorly marginated(n=112, 50%), or well-marginated(n=6, 2.7%) in patients with IDC. Spiculated and poorly marginated borders were observed in 8 patients(53.3%) and 4 patients(26.7%) respectively, in patients with ILC. Microcalcifications were seen in 88 patients(17.3%) of IDC and patients(33.3%) of ILC. Although equal or low opacities were observed more frequently in ILC and microcalcifications were noted more frequently in IDC, it was difficult to differentiate the two diseases based on mammographic findings.

    Molecular genetic markers to identify the 13% lymph node-negative mammary carcinomas that are prone to develop metastases would clearly be of considerable value in indicating those cases in need of early aggressive therapy. Representational difference analysis was used in an attempt to identify genetic alterations related to breast cancer metastasis by comparing genomic DNA from microdissected normal cells and from metastatic cells of ductal breast carcinoma patients. Representational difference analysis products yielded 10 unique metastasis-associated DNA sequences (MADS), i.e. products apparently lost in metastatic cell DNA. Of these sequences, MADS-IX was found to be lost in the transition from primary to metastasis in two out of five ductal breast carcinoma cases. This sequence was localized on chromosome 10q21 by radiation hybrid mapping and fluorescence in situ hybridization. The PTEN gene, which is also located on chromosome 10q, was detected to be present by PCR in all five cases. On the contrary, a breast carcinoma cell line, HCC-1937, which has homozygous loss of a region encompassing the PTEN gene, showed the presence of MADS-IX. PCR screening of three additional breast carcinoma cell lines with known losses in specific chromosomal regions also showed the presence of MADS-IX. These data suggest that MADS-IX possibly is part of a novel candidate metastasis-associated gene located close to the PTEN gene on chromosome 10q. The first set of PCR screening in five patient samples indicates that it could be used as a molecular marker for ductal mammary metastasis

    A 16-year-old girl presented to our unit with crampy abdominal pain, change in bowel habit, a subjective impression of weight loss and a single episode of haematochezia. She was found to have a rectosigmoid adenocarcinoma and proceeded to laparoscopic anterior resection, whereupon peritoneal metastases were discovered. She received chemotherapy and is alive and well ten month later with no radiological evidence of disease. Colorectal carcinoma is rare in the paediatric population but is increasing in incidence. Early diagnosis is critical to enable optimal outcomes.

  19. Myiasis associated with an invasive ductal carcinoma of the left breast: case study

    Directory of Open Access Journals (Sweden)

    Felipe Tavares Rodrigues

    Full Text Available ABSTRACT Most breast cancers originate in the ductal epithelium and are referred to as invasive ductal carcinoma. In this study we report on the clinical procedures adopted to diagnose myiasis in association with infiltrating metastatic breast carcinoma in a female patient. A 41 years old woman came to the Federal Hospital of Andaraí complaining of intense itching, warmth, redness and hardening of the breast, which had acquired the aspect of an orange peel. A lesion in the left breast was cavitated, dimpled, had fetid odor, and had fibrotic and infected air nodules filled with exudate and Dipteran larvae. The tissue was cleaned and 33 larvae were extracted. The patient was hospitalized and received Ivermectin. Eighteen of the larvae extracted from the patient were placed in 70% alcohol, and twelve were placed in a container with sterile wood shavings under controlled conditions until they metamorphosed into adults. The taxonomic identification of the flies revealed that the culprit was Cochliomyia hominivorax. A histopathological exam conducted three months earlier had revealed infiltrating ductal carcinoma. Two months after the myiasis treatment, the breast tissue had healed. The patient had waited ten days from the onset of the myiasis to seek treatment, and that delay interfered negatively in the prognosis of both the neoplasm and the myiasis. This study is relevant to public health in view of the strong social impact of myiasis.

    Breast cancer is the second most common cancer worldwide and the first among women. Invasive ductal carcinoma (IDC) and invasive lobular carcinoma (ILC) are the two major histological subtypes, and the clinical and molecular differences between them justify the search for new markers to distinguish them. As proteomic analysis allows for a powerful and analytical approach to identify potential biomarkers, we performed a comparative analysis of IDC and ILC samples by using two-dimensional electrophoresis and mass spectrometry. Twenty-three spots were identified corresponding to 10 proteins differentially expressed between the two subtypes. ACTB, ACTG, TPM3, TBA1A, TBA1B, VIME, TPIS, PDIA3, PDIA6, and VTDB were upregulated in ductal carcinoma compared to in lobular carcinoma samples. Overall, these 10 proteins have a key role in oncogenesis. Their specific functions and relevance in cancer initiation and progression are further discussed in this study. The identified peptides represent promising biomarkers for the differentiation of ductal and lobular breast cancer subtypes, and for future interventions based on tailored therapy.

  1. Pituitary Tumor-Transforming Gene 1 Is Expressed in Primary Ductal Breast Carcinoma, Lymph Node Infiltration, and Distant Metastases

    2013-01-01

    Full Text Available Despite the advances that have been made in the fields of molecular and cell biology, there is still considerable debate explaining how the breast cancer cells progress through carcinogenesis and acquire their metastatic ability. The lack of preventive methods and effective therapies underlines the pressing need to identify new biomarkers that can aid early diagnosis and may be targets for effective therapeutic strategies. In this study we explore the pituitary tumor-transforming gene 1 (PTTG1 expression in primary ductal breast carcinoma, lymph node infiltration, and distant metastases. Three human cell lines, 184B5 derived from normal mammary epithelium, HCC70 from a primary ductal carcinoma, and MDA-MB-361 from a breast metastasis, were used for quantifying PTTG1 mRNA expression. The PTTG1 immunohistochemical expression was carried out on specimens taken from eight patients with invasive ductal breast cancer who underwent surgical treatment and followup for five years retrospectively selected. The study demonstrated that PTTG1 is expressed gradually in primary ductal breast carcinoma, lymph node infiltration, and distant metastases. Our findings suggest that the immunohistochemical evaluation of PTTG1 expression might be a powerful biomarker of recognition and quantification of the breast cancer cells in routine pathological specimens and a potential target for developing an effective immunotherapeutic strategy for primary and metastatic breast cancer.

    A 21-year-old thoroughbred mare had a 35 x 14 x 10 cm mass involving the mammary gland. Metastases were found in the kidneys, lungs, skeletal muscles, and regional lymph nodes. Histopathologic examination of the tumor revealed a ductal solid carcinoma with extensive intraductal and intralobular involvement and focal infiltration of the adjacent stroma. The intralobular neoplasms were divided into irregularly shaped islands and sheets of polygonal and spindle-shaped epithelial cells by thick or thin fibrous connective tissue bundles. The neoplastic cells had a small or moderate amount of cytoplasm that stained faintly with eosin and round or oval hyperchromatic nuclei. Immunohistochemically, the neoplastic cells were strongly positive for Lu-5, weakly positive for AE1/AE3, vimentin, and glial fibrillary acidic protein, and negative for cytokeratin 8, cytokeratin 14, alpha-smooth muscle actin, calponin, and S100. The neoplasm was diagnosed as an invasive ductal carcinoma of the mammary gland with multiple metastases.

    Introduction Fibroadenoma is the most common benign tumor of the female breast with the highest incidence before age 30. Fibroadenoma may be associated with fibrocystic changes, proliferative epithelial changes, and extremely rarely, with non-invasive and invasive cancer. Case presentation We present a rare case of a 39 years old female with invasive ductal carcinoma arising within fibroadenoma. Conclusion There is a low percentage of fibroadenomas harboring carcinoma; however, all breast lumps should be seriously managed; extirpation and histological examination is recommended.

    Full Text Available Mammary hamartomas are uncommon benign lesions rarely associated with malignancy. We report a case of a 25-year-old female patient presenting with a lump in the left breast. Fine needle aspiration cytology showed features of invasive ductal carcinoma along with normal benign glands that were mistaken for normal breast tissue. However, the mastectomy specimen revealed the malignant mass within a larger hamartomatous mass. Mammary hamartomas are benign lesions but, on exceedingly rare occasions, they may be involved by incidental, coexisting carcinoma, as illustrated in this case report.

    Invasive lobular carcinoma of the breast is the second most common type of primary breast cancer, accounting for 8-14% of cases, but is often difficult to diagnose early. It typically shows a diffuse pattern of infiltration within the breast, resulting in a variety of often subtle radiological appearances. A similar infiltrative pattern is seen in its metastatic form, with involvement of the gastrointestinal tract, peritoneum, retroperitoneum, bone marrow, meninges and uterus occurring more frequently than with the more common infiltrating ductal carcinoma of the breast. This pictorial essay illustrates the spectrum of radiological appearances which may be encountered with both primary and secondary lobular carcinoma. Harake, M.D.J., Maxwell, A.J. and Sukumar, S.A.

    Invasive ductal carcinoma with lobular features (IDC-L) is not recognized as a distinct subtype of breast cancer, and its clinicopathologic features and outcomes are unknown. In this retrospective study, we focused on characterization of clinicopathologic features and outcomes of IDC-L and compared them to invasive ductal carcinoma (IDC) and invasive lobular carcinoma (ILC). 183 cases of IDC-L from 1996 to 2011 were compared with 1,499 cases of IDC and 375 cases of ILC. Available slides of IDC-L (n = 150) were reviewed to quantify the lobular component (≤ 20, 21-50, 51-80, >80 %), defined as small cells individually dispersed, arranged in linear cords, or in loose aggregates without the formation of tubules or cohesive nests. E-cadherin immunostain was performed to confirm ductal origin. Compared to IDC, IDC-L was more likely to have lower histologic grade (p lobular component in IDC-L had no impact on the size, nodal status, stage, or outcome. Our data suggest that although IDC-L may be a variant of IDC, with >90 % of cases being E-cadherin positive, the clinical and biological characteristics are more similar to that of ILC.

    Merkel cell carcinoma is a rare aggressive neuroendocrine carcinoma of the skin predominantly affecting elderly Caucasians. It has a high rate of local recurrence and regional lymph node metastases. It is associated with a poor prognosis. Complete spontaneous regression of Merkel cell carcinoma has been reported but is a poorly understood phenomenon. Here we present a case of complete spontaneous regression of metastatic Merkel cell carcinoma demonstrating a markedly different pattern of events from those previously published.

    Lobular carcinoma in situ (LCIS) clinically constitutes a risk factor for the subsequent development of either invasive lobular carcinoma (ILC) or invasive ductal carcinoma (IDC). In order to approach the possibility of this common precursor of both ILC and IDC, we investigated combined lobular and ductal carcinomas. Thirty-two cases of lobular carcinoma were picked up out of 773 cases of operated breast carcinomas. The histopathological detailed re-examination using immunostain of E-cadherin and β-catenin revealed a rather high frequency of combined lobular carcinomas than previous reports. Clinicopathologically, combined lobular carcinomas were younger and smaller than pure lobular carcinomas, and the cytological atypia was relatively low. These results suggested that combined lobular carcinomas could be detected in the earlier stage of breast cancer. Furthermore, the lobular and ductal components of combined carcinomas coexisted in the neighborhood and were distributed contiguously. The immunohistochemical phenotypes of both components were accorded in most combined cases. A genetic analysis using methylation-specific PCR on the HUMARA gene demonstrated that the same allele was inactivated in both lobular and ductal components in all detectable cases of combined carcinoma. Therefore, it is reasonable to assume that both lobular and ductal components of combined carcinomas are clonal and derived from the LCIS as the common precursor lesion, which may contradict the conventional concept that the lobular and ductal carcinomas arise from distinct differentiation pathways.

    Fibroadenoma is a common benign tumor observed during the second and third decades of life. Malignancy transformation in the epithelial component of a fibroadenoma is rare and can occur 20 years after its diagnosis. Mammographic findings in this phenomenon include indistinct margins and microcalcifications. Here we present a 58-year-old woman with a mobile, lateral upper quadrant mass that was rather firm when palpated. The mammography showed a lobulated mass without calcification suggestive of a benign process, most probably fibroadenoma. However the excisional biopsy contained both an intracanalicular fibroadenoma and invasive ductal carcinoma with mucinous components.

    BACKGROUND: Ductal carcinoma in situ (DCIS) is a non-invasive form of breast cancer. It is often associated with invasive ductal carcinoma (IDC), and is considered to be a non-obligate precursor of IDC. It is not clear to what extent these two forms of cancer share low-risk susceptibility loci, o...

    Full Text Available Abstract The most common sites of breast cancer metastasis are the bone, lung, liver and brain. However, colonic metastases from breast cancer are very rare in the clinic. We describe an unusual case of sigmoid colonic metastasis from invasive ductal breast cancer. With this report, we should increase the clinical awareness that any patient with a colorectal lesion and a history of malignancy should be considered to have a metastasis until proven otherwise. Early diagnosis is very important, which enables prompt initiation of systemic treatment, such as chemotherapy, endocrine therapy or both, thus avoiding unnecessary radical surgical resection and improving the prognosis.

    Full Text Available BACKGROUND There are many studies reported in the literature with respect to the Ductal Carcinoma in Situ (DCIS progressing into Invasive Ductal Carcinoma (IDC of the breast. However, there is hardly any study on the coexistence of both and its clinical significance. The aim of the study is to analyse the clinical and pathological parameters of synchronous DCIS and IDC to predict the prognostic factors. MATERIALS AND METHODS 42 patients with a final pathological diagnosis of synchronous DCIS and IDC diagnosed in 2009-11 were included in the study. Statistical analysis was done using SPSS software utilising the appropriate analytical methods. RESULTS Majority of the patients in this study group presented with early breast cancer (64.3%. Forty eight percent were Her2 subtype (ER, PR negative and HER2/neu-positive and 31% were triple negative. Eighty one percent of the IDC associated histology was Not Otherwise Specified (NOS type. Grade 3 lesions were more common (57%. Recurrence of the disease occurred in 66% of patients during a mean duration of follow up of 3.6 years with predominance of visceral metastasis (51.5%. Recurrence was more common in node positive disease (59.5%, those with lymphovascular emboli (59.5% and perinodal spread (76% on histopathological examination. CONCLUSION Synchronous DCIS and IDC disease entity appears to have an aggressive nature compared to the course of IDC alone entity. Prognostic factors relating to IDC appears to correlate well with recurrence than that of the prognostic factors of DCIS component in such synchronous setting.

  15. Radiotherapy for metastatic fibrolamellar hepatocellular carcinoma

    2013-07-01

    Full Text Available Fibrolamellar hepatocellular carcinoma (FLHCC is a rare variant of hepatocellular carcinoma (HCC that commonly affects young individuals without a prior history of liver disease. FLHCC commonly results in a better prognosis than HCC; however, the risk of recurrence and metastatic disease is high. FLHCC is typically treated by primary resection of the tumor with 50-75% cure rates. The use of radiation therapy in FLHCC has not been assessed on its own, and may show some success in a very few reported combination therapy cases. We report on the successful use of radiation therapy in a case of metastatic FLHCC to the lung following primary and secondary resections. Our treatment of the large, metastatic, pulmonary FLHCC tumor with 40 Gy in 10 fractions resulted in an 85.9% tumor volume decrease over six months. This suggests FLHCC may be a radiosensitive tumor and radiotherapy may be valuable in unresectable or metastatic tumors.

    Full Text Available Hyperplastic polyps of the stomach are regarded as benign. However, in rare cases they may contain incipient primary carcinomas. To our knowledge, breast carcinoma metastatic to a gastric hyperplastic polyp has not yet been reported. We describe the case of a 69-year-old woman to whom a gastric polyp was endoscopically excised. The patient had previously undergone a right mastectomy for mixed, invasive ductal and lobular carcinoma 5 years earlier. Histological sections from the gastric lesion showed typical features of hyperplastic polyp with foci of poorly differentiated adenocarcinoma including signet ring cells infiltrating the lamina propria. The histologic findings were consistent with a primary gastric cancer. However, the carcinoma cells were immunopositive for estrogen and progesterone receptors and GATA3 and negative for CDX2, Hep Par 1, and MUC5AC. E-cadherin showed membranous reactivity in some of the carcinoma cells while in others it was negative. Accordingly, metastatic mixed, lobular and ductal breast carcinoma was diagnosed. We conclude that metastatic adenocarcinoma mimicking primary gastric cancer can be rarely encountered in hyperplastic gastric polyps.

    2012-01-01

    Full Text Available Metastatic tumors are of great significance since few cases may represent the only symptom of an undiscovered underlying malignancy. Metastatic tumors rarely metastasize to the oral region despite the fact that many common primary neoplasms frequently metastasize to bone. The true incidence of metastatic tumors in the bones of the jaw is unknown, as jaws are not always included in radiographic skeletal surveys for metastasis. Sometimes oral metastasis may be the first evidence of metastasis from its primary site. A case of metastatic follicular thyroid carcinoma to the mandible is presented here, along with the discussion of clinical and histological features. The present case not only emphasizes the importance of considering metastasis in the differential diagnosis of a radiolucent lesion in the mandible, but also emphasizes in the improvement of the overall survival rate and treatment results by an early detection of metastatic disease.

    Breast cancer is rare in children and adolescents. In particular, there are very few cases of invasive ductal carcinoma in childhood. We report a case of invasive ductal carcinoma of the breast in a 14-year-old girl presenting as a palpable mass. While the tumor demonstrated a relatively benign appearance on ultrasound, magnetic resonance imaging revealed typical malignant features. Several polymorphisms of single nucleotide variation were observed on gene analysis. The patient underwent breast conserving surgery and received subsequent concurrent chemo-radiation therapy. An awareness that ductal carcinoma of the breast rarely occurs in children is important to detect early stage breast cancer. (orig.)

    Phyllodes tumour (PT) is a rare tumour of the female breast. The tumour clinically and radiologically mimics the features of a fibroadenoma. Ductal carcinoma in situ (DCIS) in the epithelial component of PT is a very rare finding. We present youngest ever case of a 23-year-old nulliparous woman with high-grade ductal carcinoma in situ arising within a benign phyllodes tumor. Macroscopically, it is a homogeneous tumour with solid components. Microscopically, it features typical leaf-like pattern with hypercellular stroma with high-grade ductal carcinoma in situ. To date, eight such rare cases of benign phyllodes tumour with ductal carcinoma in situ have been documented. We report the youngest case known in literature so far. As this is a very rare presentation, it poses several challenges in regard to both management and follow-up. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

    2010-07-01

    Full Text Available Advanced ductal pancreatic carcinoma (PC remains a challenge for current surgical and medical approaches. It has recently been claimed that radiofrequency ablation (RFA may be beneficial for patients with locally advanced or metastatic PC. Using the MEDLINE database, we found seven studies involving 106 patients in which PC was treated using RFA. The PC was mainly located in the pancreatic head (66.9% with a median size of 4.6 cm. RFA was carried out in 85 patients (80.1% with locally advanced PC and in 21 (19.9% with metastatic disease. Palliative surgical procedures were carried out in 41.5% of the patients. The average temperature used was 90 °C (with a temperature range of 30–105 °C and the ratio between the number of passes of the probe and the size of the tumor in centimeters was 0.5 (range of 0.36–1. The median postoperative morbidity and mortality were 28.3% and 7.5%, respectively; the median survival was 6.5 months (range of 1–33 months. In conclusion, RFA is a feasible technique: however, its safety and long-term results are disappointing; Thus, the RFA procedure should not be recommended in clinical practice for a PC patient.

    The management of in situ lesions ductal carcinoma in situ (DCIS) and lobular carcinoma in situ (LCIS) continues to evolve. These diagnoses now comprise a large burden of mammographically diagnosed cancers, and with a global trend towards more population-based screening, the incidence of these lesions will continue to rise. Because outcomes following treatment for DCIS and LCIS are excellent, there is emerging controversy about what extent of treatment is optimal for both diseases. Here we review the current approaches to the diagnosis and treatment of both DCIS and LCIS. In addition, we will consider potential directions for future management of these lesions.

    To simultaneously obtain information on diffusion and perfusion in breast lesions by diffusion-weighted magnetic resonance imaging (DWI), we analyzed three diffusion components using a triexponential function. Eighteen subjects [10 with invasive ductal carcinoma (IDC), 8 with fibroadenoma] were evaluated using DWI with multiple b-values. We derived perfusion-related diffusion, fast free diffusion, and slow restricted diffusion coefficients (Dp, Df, Ds) calculated from the triexponential function using the DWI data. Moreover, the triexponential analysis was compared with biexponential and monoexponential analyses. Each diffusion coefficient with a triexponential function was correlated to a relative enhancement ratio (RER) using dynamic contrast-enhanced MRI. In triexponential analysis, Dp and Ds in IDC were significantly higher than those for fibroadenoma. There was no correlation between each diffusion coefficient from the triexponential analysis in any of the groups (Dp, Df, and Ds), but biexponential analysis revealed a positive correlation between each diffusion coefficient in breast lesions. Strong correlations were found between Dp and RERs. Triexponential analysis thus makes it possible to obtain, in noninvasive fashion, more detailed diffusion and perfusion information in breast lesions.

    Metastasis from basal cell carcinoma of the skin is very rare with cases being documented in the lymph nodes, lung, bone and parotid gland. The main histopathological differential diagnosis is the locally arising basal cell adenocarcinoma from which it is difficult to distinguish by morphology and routine immunohistochemistry. Approximately 85 % of all reported metastatic basal cell carcinomas arise in the head and neck region. Here we present a case of basal cell carcinoma of the skin of the left lateral canthus of the eye which metastasized to the intraparotid lymph nodes with infiltration of the adjacent parotid parenchyma. More awareness and vigilance is required on the part of the reporting pathologist to consider metastasis in the presence of a parotid tumour. Features favouring metastasis include history of primary cutaneous basal cell carcinoma, histological similarity to the primary lesion and absence of any demonstrable direct extension from the skin lesion. We also review the literature on metastatic basal cell carcinoma and discuss the need for adequate follow up in high risk patients.

    Objective: To evaluate and recognize the dynamic and morphological MRI characteristics of ductal carcinoma in situ (DCIS) of the breast and provide imaging information for the early detection and treatment planning. Methods: All MRI data in 71 patients with histologically proved DCIS were analyzed retrospectively. The 71 patients were divided into two groups, N1 (pure DCIS, 44 patients) and N2 (DCIS with microinvasion, 27 patients). According to the BI-RADS descriptors, all lesions were defined as a focus (smaller than 5 mm in diameter), mass and no-mass-like three enhancement types. The morphological features (M1 = focus, M2 =linear or linear-branched, M3 = branching-ductal, M4 = segmental, M5 = focal, M6 = regional, M7 = diffuse, M8 = mass) and the time-intensity curve (TIC) pattern [type Ⅰ (persistent enhancement curves), type Ⅱ (plateau), type Ⅲ (washout) and type Ⅳ (the same enhancement as glandular tissue)] were described. Chi-square test was used for the morphological characteristics of lesions. Results: The 73 DCIS lesions were found in 71 patients, and 5.5% (n=4) were stippled lesions, 87.7% (n=64) were no-mass like lesions, 6.8% (n=5) were mass-like lesions. In no-mass-like lesions (n= 64), M3 was found in 15 cases, M4 in 34 cases, M5 in 9 cases and M6 in 6 cases, respectively, M3 and M4 were the most common distribution patterns. In N1 group (n=45) and N2 group (n=28), M3, M4, M5, M6 were found in 7 and 8, 21 and 13, 7 and 2, 3 and 3 cases, respectively. There were no statistic differences between two groups (P>0.05). In 31 showed heterogeneous enhancement, both M3 and M4 were observed in 35.5% (11/31). In 26 clustered ring enhancement lesions, M4 was observed in 88.5% (23/26). Four lesions showed reticular enhancement, 2 lesions showed a clumped enhancement and 1 lesion showed homogeneous enhancement. In 5 mass-like lesions, N1 group had 3 cases, N2 group had 2 cases. Four lesions showed lobulated margin, 4 lesions showed speculated margin, 1

    Full Text Available The objective of the current study was to assess the expression of matrix metalloproteinase 9 (MMP-9 in pancreatic ductal carcinoma and to examine its correlation with chosen clinico-anatomical parameters. The study group consisted of 36 patients with pancreatic ductal carcinoma. Tumors were stained using immunohistochemical method (NCL -MMP-9, Novocastra. No correlation was found between tumor MMP-9 expression and age, gender or grade of histological malignancy. However, statistical analysis revealed a relationship between tumor MMP-9 expression and histological type (adenocarcinoma mucinosum of pancreatic carcinoma. The expression was strongly correlated with lymph node involvement and occurrence of distant metastases (p<0.00001. The results indicate a correlation between the expression of MMP-9 in pancreatic ductal carcinoma and worse prognosis (shown by lymph node involvement and distant metastases.

  13. PTEN-Dependent Stabilization of MTSS1 Inhibits Metastatic Phenotype in Pancreatic Ductal Adenocarcinoma

    Directory of Open Access Journals (Sweden)

    Ann E. Zeleniak

    2018-01-01

    Full Text Available Pancreatic ductal adenocarcinoma (PDAC presents at metastatic stage in over 50% of patients. With a survival rate of just 2.7% for patients presenting with distant disease, it is imperative to uncover novel mechanisms capable of suppressing metastasis in PDAC. Previously, we reported that the loss of metastasis suppressor protein 1 (MTSS1 in PDAC cells results in significant increase in cellular migration and invasion. Conversely, we also found that overexpressing MTSS1 in metastatic PDAC cell lines corresponds with not only decreased metastatic phenotype, but also greater overall survival. While it is known that MTSS1 is downregulated in late-stage PDAC, the mechanism behind that loss has not yet been elucidated. Here, we build off our previous findings to present a novel regulatory mechanism for the stabilization of MTSS1 via the tumor suppressor protein phosphatase and tensin homolog (PTEN. We show that PTEN loss in PDAC cells results in a decrease in MTSS1 expression and increased metastatic potential. Additionally, we demonstrate that PTEN forms a complex with MTSS1 in order to stabilize and protect it from proteasomal degradation. Finally, we show that the inflammatory tumor microenvironment, which makes up over 90% of PDAC tumor bulk, is capable of downregulating PTEN expression through secretion of miRNA-23b, potentially uncovering a novel extrinsic mechanism of MTSS1 regulation. Collectively, these data offer new insight into the role and regulation of MTSS1in suppressing tumor cell invasion and migration and help shed light as to what molecular mechanisms could be leading to early cell dissemination in PDAC.

  18. Diagnosis and management of ductal carcinoma in situ.

    Khan, Amina; Newman, Lisa A

    2004-04-01

    Ductal carcinoma in situ (DCIS) is a preinvasive form of breast cancer that has increased in incidence over the past 25 years, primarily as a result of mammographically detected microcalcifications. Inadequately treated DCIS carries a risk for evolving into the malignant phenotype; however, the magnitude and timeline for this risk are poorly defined. Treatment options include lumpectomy with or without breast irradiation and mastectomy. The overall survival rate is 96% to 98% with any of these strategies, but the risk of local recurrence (LR) is highest after lumpectomy alone. Breast irradiation can reduce this risk from levels in excess of 40% to 10% over a 10-year follow-up period. Approximately 50% of all LR from DCIS are invasive lesions. Therefore, the occurrence of a LR after breast-conserving therapy is a potentially greater threat to the patient with DCIS compared to the patient diagnosed with invasive cancer. In patients diagnosed with invasive cancer, the risk of micrometastatic disease is present from the time of initial diagnosis. In patients with DCIS, the expectation is that a potentially 100% cure rate should be achieved with local therapy alone. Although most DCIS cases complicated by LR will be successfully salvaged with prolonged overall survival, it is critically important to take every precaution that will minimize the risk of locally recurrent disease. Therefore, radiation therapy as an adjunct to lumpectomy is essential. A subset of patients with DCIS with low-volume low-grade disease who can be safely treated by lumpectomy alone has not yet been clearly defined. Prospective studies designed to identify this category are ongoing. Inadequate margin control is the most consistent risk factor for LR that has been reported thus far, but there is no universally accepted definition for what constitutes an optimal negative margin distance. Young age at diagnosis, high nuclear grade, and comedonecrosis are other factors that have been implicated as

    Metastasis to the oral region is very rare and accounts for less than 1% of oral malignant tumors. Breast, lung, kidney, adrenal, gastro intestinal tract and prostates are most common primary tumors from which metastasis to oral region occur frequently. Metastasis from thyroid gland is extremely rare to oral region. We present an unusual case of metastatic follicular carcinoma of thyroid in maxilla. The significance of this report is that the secondary lesion was the only symptom of the primary tumor and helped us in diagnosis and treatment of disease.

    Full Text Available Background: Nonlethal genetic damage is the basis for carcinogenesis. As various gene aberrations accumulate, malignant tumors are formed, regardless of whether the genetic damage is subtle or large enough to be distinguished in a karyotype. The study of chromosomal changes in tumor cells is important in the identification of oncogenes and tumor suppressor genes by molecular cloning of genes in the vicinity of chromosomal aberrations. Furthermore, some specific aberrations can be of great diagnostic and prognostic value. Comparative genomic hybridization (CGH is used to screen the entire genome for the detection and/or location chromosomal copy number changes.Methods: In this study, frozen sections of 20 primary breast tumors diagnosed as invasive ductal carcinoma from the Cancer Institute of Imam Khomeini Hospital, Tehran, Iran, were studied by CGH to detect chromosomal aberrations. We compared histopathological and immunohistochemical findings.Results: Hybridization in four of the cases was not optimal for CGH analysis and they were excluded from the study. DNA copy number changes were detected in 12 (75% of the remaining 16 cases. Twenty-one instances of chromosomal aberrations were detected in total, including: +1q, +17q, +8q, +20q, -13q, -11q, -22q, -1p, -16q, -8p. The most frequent were +1q, +17q, +8q, -13q, similar to other studies. In three cases, we detected -13q, which is associated with axillary lymph node metastasis and was reported in one previous study. The mean numbers of chromosomal aberrations per tumor in metastatic and nonmetastatic tumors was 1.5 and 1, respectively. No other association between detected chromosomal aberrations and histopathological and immunohistochemical findings were seen.Conclusion: Since intermediately to widely invasive carcinomas are more likely to have chromosomal aberrations, CGH can be a valuable prognostic tool. Furthermore, CGH can be used to detect targeting molecules within novel amplifications

    Full Text Available ABSTRACT: Mammary gland neoplasms in cattle are rarely observed in the field veterinary diagnostics routine. Therefore, the objective of this study is to report a metastatic mammary carcinoma in a fourteen-year-old Holstein cow in the state of Santa Catarina, Brazil. The animal was diagnosed by the field veterinarian with clinical mastitis that was unresponsive to treatment, and was euthanized due to the poor prognosis. At the necropsy, multiple yellow, firm, and sometimes friable nodules, ranging from 0.1 to 20cm were observed in all mammary glands, lymph nodes, kidneys, spleen, liver, pancreas, mediastinal lymph nodes, heart, and lungs. The final diagnosis of mammary carcinoma was established through the association of clinical, necropsy, histopathological, and immunohistochemical findings. Differential diagnoses included diseases such as bovine tuberculosis and chronic fungal or bacterial mastitis.

    The aim of this study was to investigate association of radiographic (BI-RADS 4 and 5) results and prognostic factors of invasive ductal carcinomas with their histopathological subtypes. A total of 103 patients histopathologically diagnosed with invasive ductal carcinoma of breast with in last five years period were enrolled. Of them, 69 patients who had radiological reports in were included from registry of Radiology Department; Duzce University Training and Research Hospital archives. BI-RADS scores (4 and 5) of radiological reports and subtypes of ductal carcinoma were compared. Of 69 cases, 12 of 22 cases with BIRADS 4 score were Triple negative (TN) while 5 of 47 cases with BIRADS 5 score were TN (p = 0.001). The patients with TN tumors were found to have lower average age, higher grade, higher Ki67 proliferative index and fewer lymph node metastasis than those with non-TN ductal carcinomas (p = 0.048; 0.019; 0.02; 0.048 respectively). Patients who had radiological BIRADS 4 score were significantly more frequent TN type carcinoma than BI-RADS 5. It is important to pay attention to this issue when clinicians evaluate patients with BI-RADS 4 score breast lesions.

    Breast cancer (BC) shows very high incidence rates in Uruguayan women. The present factor analysis of ductal carcinoma of the breast, the most frequent histological type of this malignancy both in Uruguay and in the World, was conducted at a prepaid hospital of Montevideo, Uruguay. We identified 111 cases with ductal BC and 222 controls with normal mammograms. A factor analysis was conducted using 39 food groups, allowing retention of six factors analyzed through logistic regression in order to obtain odds ratios (OR) associated with ductal BC. The low fat and non-alcoholic beverage patterns were inversely associated (OR=0.30 and OR=0.45, respectively) with risk. Conversely, the fatty cheese pattern was positively associated (OR=4.17) as well as the fried white meat (OR=2.28) and Western patterns (OR 2.13). Ductal BC shared similar dietary risk patterns as those identified by studies not discriminating between histologic type of breast cancer.

    The authors reported an uncommon presentation of metastatic neuroendocrine carcinoma to the breast detected by Tc-99m-HYNIC-TOC SPECT/CT in a 49 years old woman who, previously, had carcinoid tumor of left main bronchus and invasive ductal carcinoma of the right breast. Later, the patient developed left breast mass. Core needle biopsy of the mass revealed poorly differentiated invasive ductal carcinoma. The disease remained stable for 12 years without any treatment on that left breast (due to patient's rejection). On the later investigation using Tc-99m-HYNIC-TOC scintigraphy examination, rather than invasive ductal carcinoma, metastatic neuroendocrine cancer was suggested. The final diagnosis was confirmed by pathological examination after surgical excision. Multiple metastatic lesions of neuroendocrine carcinoma at lung, liver, ovaries, and bones were also depicted. Due to the good behavior of the disease, patient had been doing well for eight months, without specific treatment. This report confirmed the advantage and the accuracy of Tc-99m-HYNIC-TOC scintigraphy in detection of neuroendocrine carcinoma. Furthermore, metastatic neuroendocrine tumor should be in differential diagnosis for patient with breast mass together with history of neuroendocrine tumor

    The pathological and clinical features of invasive lobular carcinoma (ILC) differ from those of invasive ductal carcinoma (IDC). Several studies have indicated that patients with ILC have a better prognosis than those with ductal carcinoma. However, no previous study has considered the molecular subtypes and histological subtypes of ILC. We compared prognosis between IDC and classical, luminal type ILC and developed prognostic factors for early breast cancer patients with classical luminal ILC. Four thousand one hundred ten breast cancer patients were treated at the Aichi Cancer Center Hospital from 2003 to 2012. We identified 1,661 cases with luminal IDC and 105 cases with luminal classical ILC. We examined baseline characteristics, clinical outcomes, and prognostic factors of luminal ILC. The prognosis of luminal ILC was significantly worse than that of luminal IDC. The rates of 5-year disease free survival (DFS) were 91.9% and 88.4% for patients with luminal IDC and luminal ILC, respectively (P = 0.008). The rates of 5-year overall survival (OS) were 97.6% and 93.1% for patients with luminal IDC and luminal ILC respectively (P = 0.030). Although we analyzed prognosis according to stratification by tumor size, luminal ILC tended to have worse DFS than luminal IDC in the large tumor group. In addition, although our analysis was performed according to matching lymph node status, luminal ILC had a significantly worse DFS and OS than luminal IDC in node-positive patients. Survival curves showed that the prognosis for ILC became worse than IDC over time. Multivariate analysis showed that ILC was an important factor related to higher risk of recurrence of luminal type breast cancer, even when tumor size, lymph node status and histological grade were considered. Luminal ILC had worse outcomes than luminal IDC. Consequently, different treatment approaches should be used for luminal ILC than for luminal IDC.

    To examine the presentation, diagnosis, and appropriate management of renal clear cell carcinoma metastasis to the thyroid gland. We describe a clinical case of solitary thyroid metastasis from renal clear cell carcinoma and present a comprehensive review of the related English-language literature. Common patterns of presentation and generalized overall management recommendations are evaluated and summarized. Eight years after nephrectomy for renal carcinoma at age 61 years, a man presented with a thyroid mass. Cytology and histopathologic surgical findings were consistent with a solitary metastasis most compatible with metastatic clear cell carcinoma from his previous renal carcinoma. After left thyroid lobectomy and isthmusectomy, the patient remains disease-free 5 years later. Although uncommon, nearly 150 cases of clinically recognized metastatic renal cell carcinoma to the thyroid have been reported in the English-language literature. Metastatic disease from the kidney to the thyroid gland can occur more than 20 years after nephrectomy with the average time interval being 7.5 years. Obtaining a full clinical history in any patient who presents with a thyroid nodule is essential to allow consideration of possible metastatic disease from previous primary tumor. Metastatic disease to the thyroid gland can be correctly diagnosed preoperatively. If metastatic renal cancer is limited to the thyroid gland only, prompt, appropriate surgical intervention can be curative. Metastatic renal carcinoma to the thyroid should be considered in any patient presenting with a thyroid mass and a medical history of renal cell carcinoma.

    Full Text Available Abstract Introduction Tumors can metastasize to the oral cavity and affect the jaws, soft tissue and salivary glands. Oral cavity metastases are considered rare and represent approximately 1% of all oral malignancies. Because of their rarity and atypical clinical and radiographic appearance, metastatic lesions are considered a diagnostic challenge. The purpose of this report is to present a rare case of a metastatic breast carcinoma mimicking a periodontal abscess in the mandible. Case presentation A 55-year-old Caucasian woman was referred to our clinic for evaluation of bisphosphonate-induced jaw osteonecrosis. She had undergone modified radical mastectomy with axillary lymph node dissection for invasive ductal carcinoma of the left breast. Her clinical examination showed diffuse swelling and a periodontal pocket of 6 mm exhibiting suppuration in the posterior right mandible. Moreover, paresthesia of the lower right lip and chin was noted. There were no significant radiographic findings other than alveolar bone loss due to her periodontal disease. Although the lesion resembled a periodontal abscess, metastatic carcinoma of the breast was suspected on the basis of the patient's medical history. The area was biopsied, and histological analysis confirmed the final diagnosis of metastatic breast carcinoma. Conclusion The general dentist or dental specialist should maintain a high level of suspicion while evaluating patients with a history of cancer. Paresthesias of the lower lip and the chin should be considered ominous signs of metastatic disease. This case highlights the importance of the value of a detailed medical history and thorough clinical examination for the early detection of metastatic tumors in the oral cavity.

    In the past three decades, the detection rate of ductal carcinoma in situ of the breast has dramatically increased due to breast screening programs. As a consequence, about 20% of all breast cancer cases are detected in this early in situ stage. Some ductal carcinoma in situ cases will progress to invasive breast cancer, while other cases are likely to have an indolent biological behavior. The presence of tumor-infiltrating lymphocytes is seen as a promising prognostic and predictive marker in invasive breast cancer, mainly in HER2-positive and triple-negative subtypes. Here, we summarize the current understanding regarding immune infiltrates in invasive breast cancer and highlight recent observations regarding the presence and potential clinical significance of such immune infiltrates in patients with ductal carcinoma in situ. The presence of tumor-infiltrating lymphocytes, their numbers, composition, and potential relationship with genomic status will be discussed. Finally, we propose that a combination of genetic and immune markers may better stratify ductal carcinoma in situ subtypes with respect to tumor evolution.

    Assessment of tumor-infiltrating lymphocytes (TILs) in histopathologic specimens can provide important prognostic information in diverse solid tumor types, and may also be of value in predicting response to treatments. However, implementation as a routine clinical biomarker has not yet been achieved. As successful use of immune checkpoint inhibitors and other forms of immunotherapy become a clinical reality, the need for widely applicable, accessible, and reliable immunooncology biomarkers is clear. In part 1 of this review we briefly discuss the host immune response to tumors and different approaches to TIL assessment. We propose a standardized methodology to assess TILs in solid tumors on hematoxylin and eosin sections, in both primary and metastatic settings, based on the International Immuno-Oncology Biomarker Working Group guidelines for TIL assessment in invasive breast carcinoma. A review of the literature regarding the value of TIL assessment in different solid tumor types follows in part 2. The method we propose is reproducible, affordable, easily applied, and has demonstrated prognostic and predictive significance in invasive breast carcinoma. This standardized methodology may be used as a reference against which other methods are compared, and should be evaluated for clinical validity and utility. Standardization of TIL assessment will help to improve consistency and reproducibility in this field, enrich both the quality and quantity of comparable evidence, and help to thoroughly evaluate the utility of TILs assessment in this era of immunotherapy.

  12. The Expression of the Zonula Adhaerens Protein PLEKHA7 Is Strongly Decreased in High Grade Ductal and Lobular Breast Carcinomas.

    Directory of Open Access Journals (Sweden)

    Jean-Christophe Tille

    Full Text Available PLEKHA7 is a junctional protein, which participates in a complex that stabilizes E-cadherin at the zonula adhaerens. Since E-cadherin is involved in epithelial morphogenesis, signaling, and tumor progression, we explored PLEKHA7 expression in cancer. PLEKHA7 expression was assessed in invasive ductal and lobular carcinomas of the breast by immunohistochemistry, immunofluorescence and quantitative RT-PCR. PLEKHA7 was detected at epithelial junctions of normal mammary ducts and lobules, and of tubular and micropapillary structures within G1 and G2 ductal carcinomas. At these junctions, the localization of PLEKHA7 was along the circumferential belt (zonula adhaerens, and only partially overlapping with that of E-cadherin, p120ctn and ZO-1, as shown previously in rodent tissues. PLEKHA7 immunolabeling was strongly decreased in G3 ductal carcinomas and undetectable in lobular carcinomas. PLEKHA7 mRNA was detected in both ductal and lobular carcinomas, with no observed correlation between mRNA levels and tumor type or grade. In summary, PLEKHA7 is a junctional marker of epithelial cells within tubular structures both in normal breast tissue and ductal carcinomas, and since PLEKHA7 protein but not mRNA expression is strongly decreased or lost in high grade ductal carcinomas and in lobular carcinomas, loss of PLEKHA7 is a newly characterized feature of these carcinomas.

    Invasive ductal carcinoma (IDC) with lobular features (IDC-L) is not recognized as a subtype of breast cancer. We previously showed that IDC-L may be a variant of IDC with clinicopathological characteristics more similar to invasive lobular carcinoma (ILC). We sought to determine the re-excision rates of IDC-L compared with ILC and IDC, and the feasibility of diagnosing IDC-L on core biopsies. Surgical procedure, multiple tumor foci, tumor size, and residual invasive carcinoma on re-excision were recorded for IDC-L (n = 178), IDC (n = 636), and ILC (n = 251). Re-excision rates were calculated by excluding mastectomy as first procedure cases and including only re-excisions for invasive carcinoma. Slides of correlating core biopsies for IDC-L cases initially diagnosed as IDC were re-reviewed. For T2 tumors (2.1-5.0 cm), re-excision rates for IDC-L (76 %) and ILC (88 %) were higher than that for IDC (42 %) (p = 0.003). Multiple tumor foci were more common in IDC-L (31 %) and ILC (26 %) than IDC (7 %) (p < 0.0001), which was a significant factor in higher re-excision rates when compared with a single tumor focus (p < 0.001). Ninety-two of 149 patients (62 %) with IDC-L were diagnosed on core biopsies. Of the 44 patients initially diagnosed as IDC, 30 were re-reviewed, of which 24 (80 %) were re-classified as IDC-L. Similar to ILC, re-excision rates for IDC-L are higher than IDC for larger tumors. Patients may need to be counseled about the higher likelihood of additional procedures to achieve negative margins. This underscores the importance of distinguishing IDC-L from IDC on core biopsies.

    Full Text Available The treatment of metastatic renal cell carcinoma (mRCC has changed dramatically in the past decade. As the number of available agents, and related volume of research, has grown, it is increasingly complex to know how to optimally treat patients. The authors are practicing medical oncologists at the US Oncology Network, the largest community-based network of oncology providers in the country, and represent the leadership of the Network's Genitourinary Research Committee. We outline our thought process in approaching sequential therapy of mRCC and the use of real-world data to inform our approach. We also highlight the evolving literature that will impact practicing oncologists in the near future.

    Fibroadenoma is a common, benign tumor of the breast, which is rarely associated with an increased risk of carcinoma. We report a case of ductal carcinoma in situ within a fibroadenoma in a 38-year-old woman. The lesion was a 1 cm, circumscribed, ovoid mass with internal calcifications evident on mammography and ultrasound, which is commonly found in fibroadenoma, but the calcifications were fine and linear, which is uncommon. This type of calcification is classified as suspicious by the American College of Radiology Breast Imaging-Reporting And Data System, and it is often correlated with comedo necrosis of ductal carcinoma, and, so, requires immediate pathologic confirmation. In our case, careful analysis of the unusual calcifications led to appropriate intervention and diagnosis. Radiologists should be aware that fibroadenomas can be malignant, and they should look for suspicious microcalcifications within a fibroadenoma.

A total of 584 breast cancers (108 ILC and 476 IDC were subjected to tissue microarray and immunohistochemical analysis for lipid metabolism-related proteins including hormone-sensitive lipase (HSL, perilipin A, fatty acid binding protein (FABP4, carnitine palmitoyltransferase (CPT-1, acyl-CoA oxidase 1, and fatty acid synthetase (FASN. HSL, perilipin A, and FABP4 expression (all p < 0.001 differed significantly: HSL and FABP4 were more frequently present in ILC, whereas perilipin A was more frequently detected in IDC. Among all invasive cancers, HSL and FABP4 were highly expressed in luminal A-type ILC (p < 0.001 and perilipin A in luminal A-type IDC (p = 0.007. Among luminal B-type cancers, HSL and FABP4 were more highly expressed in ILC (p < 0.001. Univariate analysis found associations of shorter disease-free survival with CPT-1 positivity (p = 0.004 and acyl-CoA oxidase 1 positivity (p = 0.032 and of shorter overall survival with acyl-CoA oxidase 1 positivity (p = 0.027. In conclusion, ILC and IDC exhibited different immunohistochemical lipid metabolism-related protein expression profiles. Notably, ILC exhibited high HSL and FABP4 and low perilipin A expression.

    Intraventricular tumors represent a diagnostic problem, due to a wide range of differential diagnosis, with an important variability of tumoral histological types in adult and pediatric population. Patient, Our case is represented by a patient, aged 48 years, without any history of significant personal pathology, accusing nausea, vomiting, and intensive headache. In the morning, he became confused, having hallucinations for a short period of time, and has accused drowsiness for several weeks. Imaging (CT and MRI) shows a neoformation in the third ventricle, accompanied by bilateral lateral ventricles dilatation, with predominantly annular enhancement. During surgery, through the middle third transcallosal interhemispheric approach, it was revealed a reddish, well-demarcated intraventricular mass, well vascularized and with a firm consistency. Final pathologic diagnosis was metastatic clear cell renal carcinoma. Initial postoperative evolution was good, and then neurological and respiratory condition worsened as a bronchopneumonia lead to patient's death in 12 days after surgery. Clear cell carcinoma metastasis located in the third ventricle should be taken into consideration for patients presenting a single intraventricular lesion even they have no documented primary malignancy.

    Metastasis to the thyroid gland from distant cancer is rare, and, in some cases, is a diagnostic challenge. Here, we report a case of metastatic renal cell carcinoma of the thyroid gland. A 77-year-old man presented with a neck mass detected about 1 month previously. He had undergone a right nephrectomy owing to renal cell carcinoma 14 years previously. Fine needle aspiration cytology showed a few atypical follicular cells with nuclear atypia. Under a tentative diagnosis of papillary thyroid carcinoma, a total thyroidectomy was performed. The histologic and immunohistochemical studies of the surgical specimens indicated that the thyroid masses were metastatic renal cell carcinoma to the thyroid.

    Metastatic basal cell carcinoma (MBCC) of the skin is rare in occurrence and may initially elude proper diagnosis and management. We describe a case of MBCC to cervical lymph nodes, originally evaluated and treated surgically as metastatic thyroid carcinoma. After definitive diagnosis of MBCC was made, chemotherapy and concomitant radiation treatment were initiated; however, despite these measures, the patient then developed MBCC to the lung. Risk factors and current therapeutic modalities for MBCC are also discussed. In addition to the more commonly metastasizing carcinomas, metastases from a cutaneous basal cell carcinoma primary tumor should be considered when evaluating cervical lymph node metastases of an uncertain head and neck primary.

    Background and Purpose: The pattern and distribution of 63 Patients expression as a myoepithelia/basal stem cell marker can be different between atypical ductal hyperplasia (ADH), ductal carcinoma in situ (DCIS) and invasive ductal carcinoma (IDC) and may denote basal phenotype of breast ductal carcinoma. CK8/18 is a luminal marker and may indicate a luminal phenotype of IDC and its expression in ADH and DCIS may refer to a possible precursor lesion to IDC. This work was designed to study and compare the expression of 63 Patients and cytokeratin 8/18 (CK8/l8) in some cases of ADH, DC IS and IDC. Materials and Methods: Histopathological evaluation and immunohistochemical study of anti- 63 Patients and anti-CK8/l8 was performed on selected archival cases of 7 ADH, 12 DCIS, 30 IDC of known clinico pathological data and previous estrogen receptor status (ER) for IDe. Confirmatory anti-smooth muscle actin (ASMA) expression for positive 63 Patients cases was performed. Results: 63 Patients was expressed in the peripheral rim of the myoepithelial cell layer in ADH and DCIS with occasional gabs in DCrS. It was positive and stained occasional malignant cells in 3/30 (10%) of IDC cases. Confirmatory ASMA staining decorated the same peripheral rim of cells in ADH and DCIS, but was negative in 63 Patients positive IDC cases. CK8/l8 was positive in 100% of ADH, 8/12 (66.7%) of DC IS and 22/30 (73%) of IDC cases. Combined 63 Patients and CK8/ 18 expression was noticed in 3/30 (10%) of IDe. Conclusion: It is concluded from this study that 63 Patients is specific and valuable in differentiating myoepithelial cells and is more specific and valuable than other myoepithelial markers, as ASMA and can differentiate between ADH, DCIS, IDC as it stains peripheral myoepithelial cells in ADH and DCIS with gabs in the latter and does not stain any neoplastic cells. In IDC, it is positive in malignant cells in a minority of cases which may indicate basal/stem cell/myoepithelial cell origin

    An 83-year-old woman, diagnosed with breast carcinoma 28 years earlier, presented with left hyperglobus and limitation of extraocular motility. CT and MRI showed bilateral nodular thickening of extraocular muscles. Left orbital biopsy disclosed metastatic breast carcinoma. Subsequent positron-emission tomography/CT revealed diffuse metastatic disease. To the authors' knowledge, this case represents the longest reported interval from the diagnosis of primary breast cancer to the presentation of orbital metastasis.

    Fibroadenoma is the most common breast tumor in women. Malignant transformation occurs rarely within fibroadenoma at older ages. Clinicians, radiologists, and pathologists need to be aware of malignant transformation within fibroadenomas. Radiologic studies play an important role in the diagnosis of fibroadenoma; however, radiologic findings are often nonspecific for malignancy and may appear completely benign. We detected an occult ductal carcinoma in situ that originated inside a fibroadeno...

    Full Text Available The mechanism of progression from ductal carcinoma in situ (DCIS to invasive ductal carcinoma (IDC remains largely unknown. We compared gene expression in tumors with simultaneous DCIS and IDC to decipher how diverse proteins participate in the local invasive process.Twenty frozen tumor specimens with concurrent, but separated, DCIS and IDC were microdissected and evaluated. Total RNA was extracted and microarray analysis was performed using Affymetrix GeneChip® Human Gene 1.0 ST Arrays. Microarray data were validated by quantitative real time reverse transcription-PCR (qRT-PCR and immunohistochemistry. Controls included seven pure in situ carcinomas, eight fragments from normal breast tissue, and a series of mouse breast carcinomas (MMTV-PyMT.Fifty-six genes were differentially expressed between DCIS and IDC samples. The genes upregulated in IDC samples, and probably associated with invasion, were related to the epithelial-mesenchymal transition (ASPN, THBS2, FN1, SPARC, and COL11A1, cellular adhesion (GJB2, cell motility and progression (PLAUR, PLAU, BGN, ADAMTS16, and ENPP2, extracellular matrix degradation (MMP11, MMP13, and MMP14, and growth/proliferation (ST6GAL2. qRT-PCR confirmed the expression patterns of ASPN, GJB2, ENPP2, ST6GAL2, and TMBS10. Expression of the ASPN and GJB2 gene products was detected by immunohistochemistry in invasive carcinoma foci. The association of GJB2 protein expression with invasion was confirmed by qRT-PCR in mouse tumors (P < 0.05.Conclusions: The upregulation of ASPN and GJB2 may play important roles in local invasion of breast ductal carcinomas.

    Objectives: To explore the ultrasonic findings of metastatic thyroid carcinoma and to evaluate the diagnostic value of the ultrasonic imaging for patients with metastatic thyroid neoplasm. Methods: The ultrasonic imaging characteristics of ten patients who were diagnosed with metastatic thyroid carcinoma were retrospectively analyzed. In all the cases, fine-needle aspiration cytology (FNAC) of the thyroid was performed during the clinical diagnosis. Results: The ultrasonic images of the ten patients fell into four types: multiple nodules in the thyroid, single nodule in the thyroid, diffuse calcification and heterogeneous echo. Seven cases showed speckled calcific foci. Abnormal blood flow signal was found in 9 cases. Conclusion: The ultrasonic findings of metastatic carcinoma in the thyroid gland are various and non-specific. Color Doppler ultrasound may provide ample evidence. The diagnosis depends on FNAC.

    Salivary duct carcinoma (SDC) is a high-grade salivary gland malignancy with great morphological resemblance to invasive ductal carcinoma (IDC) of the breast. Rarely, female patients may have a past history of both SDC and IDC. When these patients present with distant metastasis, accurate identification of the primary tumor is particularly difficult. Additionally, rare metastasis of SDC to the breast and IDC to the salivary (parotid) gland can also present a diagnostic challenge. Our aim was to develop an immunohistochemical panel that reliably distinguishes SDC from IDC. We included all SDCs diagnosed from 1989 to 2016 (23 cases) and 29 treatment naïve and histologically similar IDCs. All cases were stained with androgen receptor (AR), estrogen receptor-alpha (ER-α), progesterone receptor (PR), HER-2, CK5/6, p63, and beta-catenin. The great majority (> 90%) of both SDCs and IDCs reacted positively to AR. The main discrepancy in the immunohistochemical profiles was a distinctly different reactivity to ER-α, PR and HER-2. While 28 IDCs (96.6%) reacted positively to ER-α and/or PR, the majority expressing both (82.8%) with a moderate to strong staining intensity, only 2 SDCs expressed ER-α (8.7%) and 5 others expressed PR (21.7%) with only one case expressing both (P value SDC (34.8%) were positive for HER-2 while none of the IDCs were positive (P value SDC from IDC. Positive reactivity to ER-α, PR or both and negative HER-2 favors a diagnosis of IDC while ER-α, PR negative, HER-2 positive tumors are more likely SDC.

    Merkel cell carcinoma (MCC) is a rare, agressive, neurocutaneous malignancy with a high potential to metastasize. We present a 59 year-old woman referred to general surgery department with a complaint of epigastric pain. The abdominal computed tomography (CT) performed and revealed amass of 3 cm in the head of the pancreas. The significant debate in the patient's medical history was that she had a MCC in size of 5 cm removed from the left gluteal region 7 months ago. Following preoperative preparation a pancreatic oduodenectomy with Whipple procedure was performed fort hepancreatic head mass. As the tumor showed morphologically similar properties with the patient's primary neoplasm, it was accepted as a metastatic MCC. Following the operation the patient received adjuvant chemotherapy and at a 30 months follow-up it was observed that the patient is disease free and has no complications related to the disease progression or recurrence. Although MCC is an aggresive and poor prognostic tumor, good results can be obtained with correct diagnosis and proper surgical treatment. Celsius.

    Phyllodes tumor (PT) is a rare type of biphasic fibroepithelial neoplasm that may coexist with a breast tumor in rare cases. In the current study, a 52-year-old female presented with a left breast lump. Mammography and sonographic examination results suggested a diagnosis of malignant tumor. Histological analysis revealed a borderline PT with invasive ductal carcinoma (IDC) within the tumor. Due to the presence of a single micrometastasis in three of the sentinel lymph nodes, the patient underwent modified radical mastectomy. The excised tumor contained triple negative breast cancer; therefore, postoperative treatment included six cycles of chemotherapy and 25 cycles of radiotherapy. The patient exhibited no recurrence and no metastatic disease at the 23-month follow-up examination. Thus, the present study discussed the case of a female patient that presented with IDC within borderline PT and reviewed the literature on this rare type of neoplasm. Various types of breast carcinoma have been identified to coexist with PT in different masses; however, no standard therapeutic regimen has been established for the coexistence of PT and breast cancer in the same mass. The present study indicates that determination of an appropriate treatment strategy predominantly depends on the characteristics of the individual breast tumor. PMID:27073506

    A spectrum of invasive adenocarcinomas presumably arising from the anogenital mammary-like glands of the vulva has been reported. Even rarer are the cases of pure ductal carcinoma in situ that originated from these unique glandular structures. Herein, we report an 81-yr-old woman presented with an invasive well-differentiated squamous cell carcinoma of the vulva. Unexpectedly, the underlying dermis demonstrated a cystically dilated structure that displayed a layer of malignant squamous cells in the periphery, and a second centrally located population of neoplastic cells exhibiting glandular differentiation. In addition, a spindle and pleomorphic malignant cell population consistent with a sarcomatoid carcinoma was identified around the cystic structure. Scattered benign anogenital mammary-like glands were present in the adjacent dermis. The histologic and immunohistochemical findings were consistent with those of vulvar squamous cell carcinoma that has undergone sarcomatoid transformation after spreading in a pagetoid fashion into an underlying focus of ductal carcinoma in situ of anogenital mammary-like gland origin.

    Full Text Available Abstract Background Prolactin is a polypeptide hormone responsible for proliferation and differentiation of the mammary gland. More recently, prolactin's role in mammary carcinogenesis has been studied with greater interest. Studies from our laboratory and from others have demonstrated that three specific isoforms of the prolactin receptor (PRLR are expressed in both normal and cancerous breast cells and tissues. Until now, reliable isoform specific antibodies have been lacking. We have prepared and characterized polyclonal antibodies against each of the human PRLR isoforms that can effectively be used to characterize human breast cancers. Methods Rabbits were immunized with synthetic peptides of isoform unique regions and immune sera affinity purified prior to validation by Western blot and immunohistochemical analyses. Sections of ductal and lobular carcinomas were stained with each affinity purified isoform specific antibody to determine expression patterns in breast cancer subclasses. Results We show that the rabbit antibodies have high titer and could specifically recognize each isoform of PRLR. Differences in PRLR isoform expression levels were observed and quantified using histosections from xenografts of established human breast cancer cells lines, and ductal and lobular carcinoma human biopsy specimens. In addition, these results were verified by real-time PCR with isoform specific primers. While nearly all tumors contained LF and SF1b, the majority (76% of ductal carcinoma biopsies expressed SF1a while the majority of lobular carcinomas lacked SF1a staining (72% and 27% had only low levels of expression. Conclusions Differences in the receptor isoform expression profiles may be critical to understanding the role of PRL in mammary tumorigenesis. Since these antibodies are specifically directed against each PRLR isoform, they are valuable tools for the evaluation of breast cancer PRLR content and have potential clinical importance in

    Full Text Available Abstract Background Sentinel lymph node (SLN biopsy is the standard of care for the surgical assessment of the axilla during breast cancer surgery. However, the diagnostic accuracy of intraoperative frozen section analysis for confirming metastatic involvement of SLNs in cases of invasive lobular carcinoma (ILC versus that of invasive ductal carcinoma (IDC has generated controversy secondary to a frequently low-grade cytologic appearance and an often discohesive pattern displayed by metastatic lymph nodes in ILC. In the current report, we present a comparison of intraoperative frozen section analysis for confirming the presence of metastatic disease within SLNs during breast cancer surgery for ILC and IDC. Methods We evaluated the results of 131 consecutive cases of ILC from 1997 to 2008 and 133 cases of IDC (selected by a random sequence generator program from amongst 1163 consecutive cases of IDC from the same time period. All cases had at least one SLN that had both intraoperative frozen section analysis and confirmatory permanent section analysis performed. Results No statistically significant difference was found in the sensitivity (67% vs. 75%, P = 0.385, specificity (100% vs. 100%, accuracy (86% vs. 92%, P = 0.172, false negative rate (33% vs. 25%, P = 0.385, negative predictive value (81% vs. 89%, P = 0.158, and positive predictive value (100% vs. 100% for frozen section analysis for confirming the presence of metastatic disease within SLNs during breast cancer surgery for ILC and IDC. Conclusion Since there was no statistically significant difference in sensitivity, specificity, accuracy, false negative rate, negative predictive value, and positive predictive value between frozen section analysis of SLNs for patients with ILC and IDC, the clinical accuracy of confirming metastatic involvement of SLNs on frozen section analysis for ILC should not be considered inferior to the clinical accuracy for IDC. Therefore, frozen section analysis

    Acute obstructive suppurative cholangitis is a well-known clinical entity; however, acute suppuration of the pancreatic duct in the setting of pancreatic ductal obstruction is an uncommon pancreatic disorder. We report a case of acute suppuration of the pancreatic duct without either a concomitant pancreatic abscess or an infected pseudocyst, presenting as acute relapsing pancreatitis. In this case, the underlying cause of suppuration of the pancreatic duct was pancreatic ductal obstruction and chronic pancreatitis secondary to pancreas head carcinoma along with infection of Escherichia coli. Endoscopic placement of a pancreatic stent resulted in an evacuation of grayish thick pus from the distal pancreatic duct with a dramatic improvement of the disease. This case proposes the concept that acute suppuration of the pancreatic duct is a complex process involving the chronically damaged pancreas, pancreatic outflow obstruction, and subsequent bacterial infection. Antibiotic treatment is effective but temporary; therefore, the immediate drainage of the infected pancreatic duct is mandatory.

    The clinical outcomes and therapeutic strategies for infiltrating ductal carcinoma (IDC) and infiltrating lobular carcinoma (ILC) are not uniform. The primary objectives of this study were to identify the differences in the clinical characteristics and prognoses between ILC and IDC, and identify the high-risk population based on the hormone receptor status and metastasis sites. The Surveillance, Epidemiology, and End Results Program database was searched and patients diagnosed with ILC or IDC from 1990 to 2013 were identified. In total,796,335 patients were analyzed, including 85,048 withILC (10.7%) and 711,287 withIDC (89.3%). The ILC group was correlatedwith older age, larger tumor size, later stage, lower grade, metastasis disease(M1) disease, and greater counts ofpositive lymph nodesandestrogen-receptor-positive (ER)/progesterone receptor-positive (PR) positive nodes. The overall survival showed an early advantage for ILC but a worse outcome after 5 years. Regarding the disease-specific survival, the IDC cohort had advantages over the ILC group, both during the early years and long-term. In hormone status and metastasis site subgroup analyses, the ER+/PR+ subgroup had the best survival, while the ER+/PR- subgroup had the worst outcome, especially the ILC cohort. ILC and IDC had different metastasis patterns. The proportion of bone metastasis was higher in the ILC group (91.52%) than that in the IDC (76.04%), and the ILC group was more likely to have multiple metastasis sites. Survival analyses showed patients with ILC had a higher risk of liver metastasis (disease-specific survival[DSS]; P = 0.046), but had a better overall survival than the bone metastasis group (P<0.0001). We concluded that the long-term prognosis for ILC was poorer than that for IDC, and the ER+/PR- subgroup had the worst outcome. Therefore, the metastasis pattern and prognosis must be seriously evaluated, and a combination of endocrine therapy and chemotherapy should be considered. PMID

    While the deregulation of iron homeostasis in breast epithelial cells is acknowledged, iron-related alterations in stromal inflammatory cells from the tumor microenvironment have not been explored. Immunohistochemistry for hepcidin, ferroportin 1 (FPN1), transferrin receptor 1 (TFR1) and ferritin (FT) was performed in primary breast tissues and axillary lymph nodes in order to dissect the iron-profiles of epithelial cells, lymphocytes and macrophages. Furthermore, breast carcinoma core biopsies frozen in optimum cutting temperature (OCT) compound were subjected to imaging flow cytometry to confirm FPN1 expression in the cell types previously evaluated and determine its cellular localization. We confirm previous results by showing that breast cancer epithelial cells present an ‘iron-utilization phenotype’ with an increased expression of hepcidin and TFR1, and decreased expression of FT. On the other hand, lymphocytes and macrophages infiltrating primary tumors and from metastized lymph nodes display an ‘iron-donor’ phenotype, with increased expression of FPN1 and FT, concomitant with an activation profile reflected by a higher expression of TFR1 and hepcidin. A higher percentage of breast carcinomas, compared to control mastectomy samples, present iron accumulation in stromal inflammatory cells, suggesting that these cells may constitute an effective tissue iron reservoir. Additionally, not only the deregulated expression of iron-related proteins in epithelial cells, but also on lymphocytes and macrophages, are associated with clinicopathological markers of breast cancer poor prognosis, such as negative hormone receptor status and tumor size. The present results reinforce the importance of analyzing the tumor microenvironment in breast cancer, extending the contribution of immune cells to local iron homeostasis in the tumor microenvironment context

    The aim of this study was to determine the incidence rate and clinical features of second primary pancreatic ductal carcinoma (SPPDC) in the remnant pancreas after pancreatectomy for pancreatic ductal carcinoma (PDC). Data of patients undergoing R0 resection for PDC at a single high-volume center were reviewed. SPPDC was defined as a tumor in the remnant pancreas after R0 resection for PDC, and SPPDC met at least one of the following conditions: 1) the time interval between initial pancreatectomy and development of a new tumor was 3 years or more; 2) the new tumor was not located in contact with the pancreatic stump. We investigated the clinical features and treatment outcomes of patients with SPPDC. This study included 130 patients who underwent surgical resection for PDC between 2005 and 2014. Six (4.6%) patients developed SPPDC. The cumulative 3- and 5-year incidence rates were 3.1% and 17.7%, respectively. Four patients underwent remnant pancreatectomy for SPPDC. They were diagnosed with the disease in stage IIA or higher and developed recurrence within 6 months after remnant pancreatectomy. One patient received carbon ion radiotherapy and survived 45 months. One patient refused treatment and died 19 months after the diagnosis of SPPDC. The incidence rate of SPPDC is not negligible, and the cumulative 5-year incidence rate of SPPDC is markedly high. Post-operative surveillance of the remnant pancreas is critical for the early detection of SPPDC, even in long-term survivors after PDC resection. Copyright © 2016 IAP and EPC.

    Full Text Available Abstract Background Although it is well known that the pancreatic ductal carcinoma may develop having a relationship to the mucous gland hyperplasia (MGH with atypia (PanIN-1B by PanIN system, the starting point of this atypical MGH is unclear. To know it, we examined the pancreas tissue using many methods described below. Methods 1. Twenty-seven surgically resected pancreas tissue specimens, including pancreatic ductal carcinomas (PDC, chronic pancreatitis and normal pancreas, were investigated using immunohistochemical stainings for MUC1, MUC6, 45M1, Ki67 and p53. 2. DNA extraction and analysis of K-ras mutation at codon 12 using microdissection method: The paraffin blocks with 16 regions including the intercalated duct cell (IC adjacant to the atypical MGH were prepared for DNA extraction. Mutation of K-ras codon 12 was analized and compared in enriched polymerase chain reaction-enzyme-linked minisequence assay (PCR-ELMA. Results 1. In the normal pancreas, although no positive cell was seen in 45M1, p53, Ki67, the cytoplasm of IC were always positive for MUC1 and sometimes positive for MUC6. In the pancreas with fibrosis or inflammation, MGH was positive for MUC6 and 45M1. And atypical MGH was positive for MUC1, MUC6 and 45M1. Some IC adjacent to the atypical MGH was positive for Ki67 as well as atypical MGH. The carcinoma cells in all cases of PDC were diffusely positive for MUC1, 45M1, p53 and Ki67, and focally positive for MUC6. 2. In K-ras mutation, we examined the regions including IC adjacent to the atypical MGH, because the immunohistochemical apomucin stainings of these regions resembled those of PDC as decribed above. And K-ras mutation was confirmed in 12 of 16 regions (75%. All mutations were a single mutation, in 6 regions GTT was detected, in 4 regions GAT was detected and in 2 region AGT was detected. Conclusion Some intercalated duct cell may be the starting point of the pancreatic ductal carcinoma, because the exhibitions of

    Full Text Available About 10% of metastatic urothelial carcinoma overexpress oncogenic HER2/neu receptor. Recent preliminary data suggest that patients with this particular molecular subset could benefit from trastuzumab therapy, which specifically targets the receptor and thus inhibits downstream activation pathway. Here we report a case illustrating this clinical benefit, with complete response reported as third line therapy in a heavily pretreated patient with diffuse metastatic urothelial carcinoma of the bladder. It also highlights the usefulness of 18-Fluorodeoxyglucose Positron Emission Tomography (18-FDG PET as a biomarker for response to trastuzumab.

    Skeletal muscle is one of the most unusual sites of metastasis from any malignancy. We report a patient with rapidly progressive contractures due to metastatic infiltration of a carcinoma of unknown origin into the skeletal muscle. This 61-year-old man presented with a 1-month history of rapidly evolving, painful restriction of mobility of his right arm and his legs. Computed tomography showed diffuse metastatic nodules in all muscles, particularly in the hip abductors. Muscle biopsy revealed extensive infiltration of the muscle with carcinoma cells. (orig.)

    We report a case of a 73-year-old lady with transitional cell carcinoma and no evidence of metastatic disease presenting with gradual weight loss, pretibial swelling and painful weightbearing. Investigations revealed a lesion of the right tibial diaphysis. The radiological and clinical appearance was that of primary osteosarcoma. Biopsy results revealed metastatic transitional cell carcinoma of the tibia. Intramedullary nailing was performed which relieved pain on weightbearing. The patient declined radiotherapy and was started on a palliative care regimen. This case illustrates the importance of histological diagnosis in the treatment of diaphyseal lesions.

    Morphometric features of nuclear perimeter, nuclear area, feret ratio, and feret circle were studied in a series of 64 cases of ductal carcinoma in situ (DCIS) of the breast in Singapore women. The results were compared with pathologic parameters of tumor size, nuclear grade, necrosis, cell polarization, and architectural pattern. There was statistically significant correlation between nuclear perimeter and area with all the pathologic parameters, with the strongest association observed for nuclear grade (P parameters and feret ratio or circle, indicating that nuclear roundness or lack of it did not factor as a significant component in the pathologic assessment.

    Full Text Available Abstract Background Invasive ductal and lobular carcinomas (IDC and ILC are the most common histological types of breast cancer. Clinical follow-up data and metastatic patterns suggest that the development and progression of these tumors are different. The aim of our study was to identify gene expression profiles of IDC and ILC in relation to normal breast epithelial cells. Methods We examined 30 samples (normal ductal and lobular cells from 10 patients, IDC cells from 5 patients, ILC cells from 5 patients microdissected from cryosections of ten mastectomy specimens from postmenopausal patients. Fifty nanograms of total RNA were amplified and labeled by PCR and in vitro transcription. Samples were analysed upon Affymetrix U133 Plus 2.0 Arrays. The expression of seven differentially expressed genes (CDH1, EMP1, DDR1, DVL1, KRT5, KRT6, KRT17 was verified by immunohistochemistry on tissue microarrays. Expression of ASPN mRNA was validated by in situ hybridization on frozen sections, and CTHRC1, ASPN and COL3A1 were tested by PCR. Results Using GCOS pairwise comparison algorithm and rank products we have identified 84 named genes common to ILC versus normal cell types, 74 named genes common to IDC versus normal cell types, 78 named genes differentially expressed between normal ductal and lobular cells, and 28 named genes between IDC and ILC. Genes distinguishing between IDC and ILC are involved in epithelial-mesenchymal transition, TGF-beta and Wnt signaling. These changes were present in both tumor types but appeared to be more prominent in ILC. Immunohistochemistry for several novel markers (EMP1, DVL1, DDR1 distinguished large sets of IDC from ILC. Conclusion IDC and ILC can be differentiated both at the gene and protein levels. In this study we report two candidate genes, asporin (ASPN and collagen triple helix repeat containing 1 (CTHRC1 which might be significant in breast carcinogenesis.

    Since the mid-2000s, the field of metastatic renal cell carcinoma (mRCC) has experienced a paradigm shift from non-specific therapy with broad-acting cytokines to specific regimens, which directly target the cancer, the tumour microenvironment, or both.Current guidelines recommend targeted therapies with agents such as sunitinib, pazopanib or temsirolimus (for people with poor prognosis) as the standard of care for first-line treatment of people with mRCC and mention non-specific cytokines as an alternative option for selected patients.In November 2015, nivolumab, a checkpoint inhibitor directed against programmed death-1 (PD-1), was approved as the first specific immunotherapeutic agent as second-line therapy in previously treated mRCC patients. To assess the effects of immunotherapies either alone or in combination with standard targeted therapies for the treatment of metastatic renal cell carcinoma and their efficacy to maximize patient benefit. We searched the Cochrane Library, MEDLINE (Ovid), Embase (Ovid), ISI Web of Science and registers of ongoing clinical trials in November 2016 without language restrictions. We scanned reference lists and contacted experts in the field to obtain further information. We included randomized controlled trials (RCTs) and quasi-RCTs with or without blinding involving people with mRCC. We collected and analyzed studies according to the published protocol. Summary statistics for the primary endpoints were risk ratios (RRs) and mean differences (MD) with their 95% confidence intervals (CIs). We rated the quality of evidence using GRADE methodology and summarized the quality and magnitude of relative and absolute effects for each primary outcome in our 'Summary of findings' tables. We identified eight studies with 4732 eligible participants and an additional 13 ongoing studies. We categorized studies into comparisons, all against standard therapy accordingly as first-line (five comparisons) or second-line therapy (one comparison

    Full Text Available We report a very rare case of extensive ductal carcinoma in situ (DCIS of the breast with secretory features in a 30-year old Japanese woman. The patient presented with a nodule in the lower inner quadrant of the left breast measuring approximately 2-3 cm, accompanied by an irregular tumor shadow with segmental microcalcification on mammography. These findings suggested malignancy, and excisional biopsy was performed following core needle biopsy. Pathological diagnosis was that of DCIS with secretory features. A treatment plan of simple mastectomy and sentinel lymph node biopsy was chosen. Most previous reports have only described invasive secretory carcinoma of the breast. We have only been able to find 2 case reports of non-invasive secretory lesion in the English literature to date. Because the characteristics of this lesion are not widely known, we thought it important to share our findings.

    Hyperspectral imaging (HSI) is a non-invasive optical imaging modality that shows the potential to aid pathologists in breast cancer diagnoses cases. In this study, breast cancer tissues from different patients were imaged by a hyperspectral system to detect spectral differences between normal and breast cancer tissues. Tissue samples mounted on slides were identified from 10 different patients. Samples from each patient included both normal and ductal carcinoma tissue, both stained with hematoxylin and eosin stain and unstained. Slides were imaged using a snapshot HSI system, and the spectral reflectance differences were evaluated. Analysis of the spectral reflectance values indicated that wavelengths near 550 nm showed the best differentiation between tissue types. This information was used to train image processing algorithms using supervised and unsupervised data. The K-means method was applied to the hyperspectral data cubes, and successfully detected spectral tissue differences with sensitivity of 85.45%, and specificity of 94.64% with true negative rate of 95.8%, and false positive rate of 4.2%. These results were verified by ground-truth marking of the tissue samples by a pathologist. In the hyperspectral image analysis, the image processing algorithm, K-means, shows the greatest potential for building a semi-automated system that could identify and sort between normal and ductal carcinoma in situ tissues.

    Fibroadenoma is the most common form of benign breast tumor and the most common breast tumor in women under 30 years of age. However, carcinoma arising within a fibroadenoma is unusual, with over 100 cases reported in the literature. Histological diagnosis is typically unexpected. A 46-year-old female with no family history of breast malignancies was admitted for an elastic hard lump in the upper-outer quadrant of her right breast. At a clinic that she visited previously, her condition was diagnosed by core needle biopsy with four specimens showing fibroadenoma with borderline atypical ductal hyperplasia at pathology. Excisional biopsy was recommended for pathological diagnosis. The patient requested a definitive diagnosis and alternative treatment to tumorectomy. More biopsy specimens were needed for pathological diagnosis; therefore, ultrasonography-guided vacuum-assisted core needle biopsies were obtained, confirming ductal carcinoma in situ with questionable microinvasion of intracanalicular- and pericanalicular-type fibroadenoma. Right breast-conserving surgery and sentinel lymph node biopsy were immediately performed for radical therapy. We present this case to increase awareness of this entity and stress the need for histological evaluation of some breast masses.

    Polarization imaging has been recognized as a potentially powerful technique for probing the microstructural information and optical properties of complex biological specimens. Recently, we have reported a Mueller matrix microscope by adding the polarization state generator and analyzer (PSG and PSA) to a commercial transmission-light microscope, and applied it to differentiate human liver and cervical cancerous tissues with fibrosis. In this paper, we apply the Mueller matrix microscope for quantitative detection of human breast ductal carcinoma samples at different stages. The Mueller matrix polar decomposition and transformation parameters of the breast ductal tissues in different regions and at different stages are calculated and analyzed. For more quantitative comparisons, several widely-used image texture feature parameters are also calculated to characterize the difference in the polarimetric images. The experimental results indicate that the Mueller matrix microscope and the polarization parameters can facilitate the quantitative detection of breast ductal carcinoma tissues at different stages.

    ERC/mesothelin gene (MSLN) encodes a precursor protein, which is cleaved by proteases to generate N-ERC/mesothelin and C-ERC/mesothelin. N-ERC/mesothelin is a soluble protein, also known as megakaryocyte-potentiating factor, which is released into extracellular space. N-ERC/mesothelin is known to be a serum marker of mesothelioma. We have previously developed an enzyme-linked immunosorbent assay system for N-ERC/mesothelin, which can detect mesothelioma. C-ERC/mesothelin is expressed in normal mesothelial cell, pancreatic cancers, ovarian cancers, mesotheliomas and some other cancers. Pancreatic ductal carcinoma remains a fatal disease because its diagnosis often occurs very late. In this study, we examined ERC/mesothelin expression in human pancreatic cancer cell lines (MIA-PaCa2, PK-1, KP-3, TCC-PAN2, PK-59 and PK-45H) by reverse transcription-polymerase chain reaction and immunoblotting and N-ERC/mesothelin concentration in the supernatant of cultured cancer cells by the ELISA system. We also investigated C-ERC/mesothlein expression in human pancreatic ductal carcinoma tissues by immunostaining using 5B2 anti-mesothelin monoclonal antibody and N-ERC/mesothelin concentration in sera obtained from patients with pancreatic ductal carcinoma via ELISA. In vitro, N-ERC/mesothelin concentration in cell culture medium nearly correlated with the expression level of C-ERC/mesothelin. Although C-ERC/mesothelin was frequently expressed in human pancreatic ductal carcinoma, serum N-ERC/mesothelin concentration of cancer patients was equivalent to healthy controls. N-ERC/mesothelin was not useful as a serum marker of pancreatic ductal carcinoma, but because of frequent expression, C-ERC/mesothelin might be useful as a target of molecular imaging and immunotherapy.

    2011-03-01

    Full Text Available Merkel cell carcinoma (MCC is an uncommon cutaneous malignant tumor that presents as a rapidly growing skin nodule on sun-exposed areas of the body. MCC is aggressive with regional nodal and distant metastases to the skin, lung, and bones. There have been no reports of metastatic MCC to the mesentery and 6 reports describing metastasis to the small intestine. We present a case of metastatic MCC to the mesentery with infiltration to the small bowel, 8 years after original tumor resection. This is the 5th metastasis and it encased the small bowel resulting in a hair-pin loop contributing to the unusual clinical presentation. Although MCC metastatic to the bowel is uncommon, it is not rare. It is important to recognize the unusual manifestations of this disease as they are becoming more common in the future. Routine radiologic surveillance and thorough review of systems are important to patient follow-up.

    2014-09-01

    Fibroadenoma (FA) is the most common benign tumor of the female breast and several studies have reported that women with it have increased risk of breast cancer. While the ductal carcinoma in situ (DCIS) is a very early form of breast cancer. Thus, early detections of FA and DCIS are critical for improving breast tumor outcome and survival. In this paper, we use multiphoton microscopy (MPM) to obtain the high-contrast images of fresh, unfixed, unstained human breast specimens (normal breast tissue, FA and DCIS). Our results show that MPM has the ability to identify the characteristics of FA and DCIS including changes of duct architecture and collagen morphology. These results are consistent with the histological results. With the advancement of MPM, the technique has potential ability to serve as a real-time noninvasive imaging tool for early detection of breast tumor.

    2009-03-01

    Full Text Available The occurrence of breast carcinoma is common in women. Ductal carcinoma in situ (DCIS of the breast is breast carcinoma with tumor cells which exist in the breast glandular duct and have not infiltrated into stroma. Retrospective study has been made on 23 paraffin blocks of morphological breast DCIS variants, namely kribriform, solid, and komedo. One way to find out DCIS aggressiveness is by detecting myoepithelial cells surrounding the breast duct indicating the integrity of the basal membrane. Detection of myoepithelial cells by means of immunohistochemical technique is done by using a selective marker for breast myoepithelial cells, namely p63. The aim of this research was predict tumor infiltration through decrease of immunoexpression of p63 in myoepithelial cells of morphological variants: cibriform, solid, and komedo of breast DCIS. This research was performed at Pathology Anatomy Laboratory of Medical Faculty of Padjadjaran University/RSUP Hasan Sadikin Bandung from Juli 2005 to September 2006. The result of the research indicated that immunoexpression of p63 in myoepithelial cells of morphological breast DCIS variants - cibriform, solid and komedo - did not show any significant difference (p<: 0,05. This indicated that tumor infiltration can occur in every breast DCIS morphological variant being studied, namely cribriform, solid, and comedo. The conclusion of this research is that decrease of immunoexpression of p63 in myoepithelial cells of morphological variants: cibriform, solid, and comedo of breast DCIS predict the presence of tumor infiltration.

    Full Text Available Metastasis confined to eyelids are rare, representing less than 1% of malignant eyelid lesions. More than 50% of all eyelid metastasis are reported to have the breast as the most common primary origin. Two cases of metastatic eyelid disease associated with primary breast carcinoma are described. These lesions were the first sign of metastatic systemic disease. Case 1: An 80-year old woman with no significant ophthalmological history complaining of a discrete painless lesion in the left upper eyelid. She had been diagnosed 10 years before as infiltrated ductal carcinoma of right mammary gland with no reference of metastatic disease. Case 2: A 77-year old woman who attends our ophthalmology service came complaining of a four-month history of a painless swelling and erythema of right lower eyelid. The past medical history was significant for infiltrated ductal carcinoma on right mammary gland 2 years before the ocular manifestation. Breast carcinoma is notorious for its presentation diversity. Metastatic disease should be considered as differential diagnosis of eyelid lesions. Although rare, these lesions can be an initial sign of systemic malignancy.Metástase confinada às pálpebras é rara, representando menos de 1% das lesões malignas palpebrais. Mais de 50% das metástases palpebrais são relatadas como tendo a mama como sítio primário. Relatamos dois casos de doença metastática palpebral associada a carcinoma primário de mama. Estas lesões foram o primeiro sinal de doença metastática sistêmica. Caso 1: Paciente do sexo feminino, 80 anos de idade sem antecedentes oftalmológicos apresentando discreta lesão nodular indolor na pálpebra superior do olho esquerdo.

    Background. The purpose of this study is to report our personal experience of 22 cases of ductal carcinoma in situ (DCIS) studied with magnetic resonance imaging (MRI). Patients and methods. From September 1995 to December 2001, 22 women diagnosed with DCIS lesions underwent contrast enhanced MRI within 7 days after mammographic examination. Dynamic MRI was performed with a 1 T system, using a three dimensional fast low angle shot (FLASH) pulse sequence before and after contrast media administration. We evaluated the morphologic features of the enhancement, the enhancement rate and the signal time intensity curve. Pathology was obtained in all cases. Results. The results of histopatological examination included: 15 DCIS and 7 DCIS with associated microinvasive component or microfoci of invasive ductal carcinoma (IDC). On MRI, 21 of 22 (95%) DCIS lesions showed contrast enhancement. Fourteen out of 15 pure DCIS lesions demonstrated respectively a low (3), undeterminate (5), and strong (6) enhancement. Morphologically, the enhancing lesion was focal in 7, segmental in 4, and with linear branching in 3 cases. Wash out was found in 4 cases, plateau curve in 8 and Type I curve in 2 cases. Multifocality was present in 5 cases. All DCIS with associated microinvasion demonstrated contrast enhancement: 1/7 cases showed a low enhancement, 2/7 showed an indeterminate enhancement and 4/7 showed a strong enhancement. Morphologically, the enhancing lesion was focal in 3/9, segmental in 5 and with linear branching in 1 case. The wash out was demonstrated in 3/7 cases, plateau curve in 3 and Type 1 curve in 1 case. Multifocality was present in 3 cases. Conclusions. In conclusion, the sensitivity of MRI for DCIS detection is lower than that achieved for invasive breast cancer; however, contrast-enhanced MRI can depict foci of DCIS that are mammographically occult. The MRI technique is of complementary value for a better description of tumor size and detection of additional

    This study investigated whether texture-based imaging parameters could identify invasive components of ductal carcinoma in situ (DCIS). We enrolled 65 biopsy-confirmed DCIS patients (62 unilateral, 3 bilateral) who underwent {sup 18}F-FDG PET, diffusion-weighted imaging (DWI), or breast-specific gamma imaging (BSGI). We measured SUV{sub max} and intratumoral metabolic heterogeneity by the area under the curve (AUC) of cumulative SUV histograms (CSH) on PET, tumour-to-normal ratio (TNR) and coefficient of variation (COV) as an index of heterogeneity on BSGI, minimum ADC (ADC{sub min}) and ADC difference (ADC{sub diff}) as an index of heterogeneity on DWI. After surgery, final pathology was categorized as pure-DCIS (DCIS-P), DCIS with microinvasion (DCIS-MI), or invasive ductal carcinoma (IDC). Clinicopathologic features of DCIS were correlated with final classification. Final pathology confirmed 44 DCIS-P, 14 DCIS-MI, and 10 IDC. The invasive component of DCIS was significantly correlated with higher SUV{sub max} (p = 0.017) and lower AUC-CSH (p < 0.001) on PET, higher TNR (p = 0.008) and COV (p = 0.035) on BSGI, lower ADC{sub min} (p = 0.016) and higher ADC{sub diff} (p = 0.009) on DWI, and larger pathologic size (p = 0.018). On multiple regression analysis, AUC-CSH was the only significant predictor of invasive components (p = 0.044). The intratumoral metabolic heterogeneity of {sup 18}F-FDG PET was the most important predictor of invasive components of DCIS. (orig.)

    To investigate the correlation between mammographic findings of infiltrating ductal carcinoma (IDC), patient age and pathologic grading. The study included 103 cases of infiltrating ductal carcinoma in 102 women who during the preceding three years had undergone mammography and surgery. The mammograms were retrospectively reviewed by two radiologists. The mean age of the patients was 45.2 (range 26 - 74) years and the age distribution was seven in the 3rd decade, 37 in the 4th, 29 in the 5th, 24 in the 6th, and six in the 7th or above. Thirty-three lesions were histologic. Grade 1, 59 were Grade 2 and 11 were Grade 3. Ten (9.7%) of 103 cases, all of whom were younger than 50, were missed during mammographic diagnosis. On mammograms, primary findings of breast malignancy were found in 54 (74%) of 73 patients younger than 50 and 27 (90%) of 30 patients older than 51. Mass with or without microcalcification was found in 45 patients (62%) younger than 50 and in 26 (87%) older than 51. Nine (12%) and 3 (10%) in each age group showed secondary findings. There was no correlation between age distribution and histologic grading. Seventy-three percent of Grade 1 lesions and 78% of those of Grade 3 showed primary findings. Five lesions in each of Grade 1 and 2 were missed at mammographic interpretation, but this was not statistically significant (p=0.250). In all 11 Grade 3 cases, breast cancer were manifested as primary findings, but this was not statistically significant (p=0.203). The majority of IDC were detected by mammography, but 9.7% of IDC patients, all younger than 50, were misdiagnosed. Most IDC was manifested as primary findings, particularly in patients aged over 51. There were no differences in pathologic grading according to age distribution. All histologic Grade 3 lesions were detected by mammography.

    Full Text Available Breast cancer is a major cause of mortality in women due to malignant diseases and is the most prevalent type of cancer in western countries. According to investigations which has been done in Iran so far, the prevalence of disease in our country is also very high, therefore complete attention to clinical and pathological findings of this disease would be extremely essential. In this study, the direct relationship between axillary lymph node involvement and the aggressiveness of invasive ductal carcinoma has been brought into consideration. This study is a case series of 90 patients which all of them have had radical mastectomy because of breast cancer and all their samples has been referred to the center of pathology of Imam hospital. Based on modified Bloom-Richardson grading, all the samples have been graded. The study of all lymph node samples related to above cases has also been conducted along with the main study. The most frequent ages of disease was 31 to 40 and left breast had most involvement. From all cases, 12.2% were in grade I with 27.2% lymph node involvement, 66.7% grade II with 73.4% lymph node involvement and 21.1% in grade III with 100% lymph node involvement (P=0.00008. Based on statistical analysis we concluded that the axillary lymph node involvement in breast cancer is strongly associated with the aggressiveness of invasive ductal carcinoma. This important point should not be neglected in planning for treatment of this kind of disease.

    A 76-year-old man underwent a subtotal parotidectomy for removal of a 3 cm. multicystic mass. The tumor was a salivary gland carcinoma, with both infiltrating and intraductal/intra-acinar components, exhibiting three histologic patterns: cribriform, papillary, and comedo-like. Immunohistochemical stain for keratin by the immunoperoxidase technique was strongly reactive in the vast majority of the tumor cells, indicating ductal differentiation of the tumor. Ultrastructural studies indicated primarily ductal differentiation of the tumor cells, with additional areas of acinous and myoepithelial differentiation.

    The objective of this study was to compare the differential expression of established histopathologic and biologic markers of proliferation, apoptosis, and angiogenesis in invasive lobular carcinoma (ILC) and invasive ductal carcinoma (IDC) in a group of axillary node-negative breast cancers. Two hundred twenty patients with axillary node-negative ILC and IDC who underwent surgery at the University of Texas M. D. Anderson Cancer Center between 1978 and 1995 had tissue available for analysis. Of these, 206 (94%) had IDC and 14 (6%) had ILC. Estrogen receptors, progesterone receptors, tumor and stromal expression of vascular endothelial growth factor receptor 2, CD44, laminin-5, E-cadherin, and topoisomerase-2 were evaluated by immunohistochemical analysis. HER2/neu and alpha6beta4 integrin were evaluated by in situ hybridization. The Fisher exact test was used to calculate significant differences between ILC and IDC. Median age was 59 years. Invasive lobular carcinoma was more likely to occur in patients aged > 50 years. Invasive lobular carcinoma tended to be > 2 cm (50% vs. 39%), have a nuclear grade of 1/2 (100% vs. 72%), be estrogen receptor positive (93% vs. 70%), HER2/neu negative (92% vs. 68%), have high CD44 expression (31% vs. 16%), low stromal vascular endothelial growth factor receptor 2 expression (36% vs. 47%), no E-cadherin expression (0 vs. 90%), and low laminin-5 expression (15% vs. 25%), compared with IDC. Invasive lobular carcinoma and IDC might be distinct histologic types of breast cancer with different expression of biologic markers. These differences, not all being statistically significant in this small study, might generate hypotheses to develop tailored options for future systemic therapy.

    Breast invasive ductal carcinoma (IDC) and invasive lobular carcinoma (ILC) have different metastatic patterns, but the exact pattern of metastases from ILC is poorly known. This study aimed to determine the frequency of ILC metastases in atypical locations, with an emphasis on gastric metastases. Patients with ILC treated at the Saint-Sacrement Hospital (Quebec City, Canada) and the Maisonneuve-Rosemont Hospital (Montreal, Canada) between January 2003 and December 2009 were retrospectively reviewed. Demographic, clinical, and follow-up data were retrieved from the medical charts. Metastases that were diagnosed during follow-up were recorded. Among the 481 patients with ILC, 74 (15.4%) were diagnosed with metastases after a median follow-up of 46 months. Among these 74 patients, 41.9% had metastases in atypical sites. Five patients were diagnosed with histologically confirmed gastric metastases of ILC. Metastases of breast ILC to atypical sites might be more frequent than previously reported. Clinicians should keep a high level of suspicion when a patient with a history of ILC develops digestive symptoms. It is important to differentiate metastases from a primary GI tumor by using immunohistochemical markers. J. Surg.

    Full Text Available Cancer of the male breast is an uncommon event with metastases to the breast occurring even less frequently. Prostate carcinoma has been reported as the most frequent primary to metastasize to the breast; however, the reverse has not been previously reported. Herein, we present, for the first time, a case of breast carcinoma metastasizing to the prostate gland. Prostate needle core biopsy revealed infiltrative nests of neoplastic epithelioid cells, demonstrated by immunohistochemistry (IHC to be positive for GATA3 and ER and negative for PSA and P501S. A prostate cocktail by IHC study demonstrated lack of basal cells (p63 and CK903 and no expression of P501S. The patient’s previous breast needle core biopsy showed strong ER positivity and negative staining for PR and HER2. Similar to the prostate, the breast was negative for CK5/6, p63, and p40. This case demonstrates the importance of considering a broad differential diagnosis and comparing histology and IHC to prior known malignancies in the setting of atypical presentation or rare tumors.

    Invasive ductal carcinoma (IDC) and invasive lobular carcinoma (ILC) have distinct clinical, pathologic, and genomic characteristics. The objective of the current study was to compare the relative impact of adjuvant chemotherapy on the survival of patients with ILC versus those with IDC. Women with estrogen receptor (ER)-positive, human epidermal growth factor receptor 1 (HER2) -negative, stage I/II IDC and ILC who received endocrine therapy were identified from the 2000 to 2014 California Cancer Registry. Patient, tumor, and treatment characteristics were collected. Ten-year overall survival (OS) was estimated using the Kaplan-Meier method and Cox proportional-hazards modeling. In total, 32,997 women with IDC and 4638 with ILC were identified. The receipt of chemotherapy significantly decreased during the study for both subtypes. For patients with IDC, the 10-year OS rate was 95% among those who received endocrine therapy alone versus 93% (P cancer treatment for a large proportion of patients with breast cancer.

  3. Mammary Ductal Carcinoma In Situ: A Fresh Look at Architectural Patterns

    Gabriel Scripcaru

    2012-01-01

    Full Text Available Mammary ductal carcinoma in-situ (DCIS, a malignant appearing lesion on cytological and histological grounds, is in fact a non-obligate precancer. DCIS is difficult to manage and is sometimes treated more aggressively than invasive carcinoma. Although most DCIS classifications take into account the architectural growth pattern, when it comes to architecture, the literature is full of contradictory information. We examined 289 breast cancers and found DCIS in 265 of the cases. The majority of the DCIS cases were seen in the setting of invasive cancer and only 9% of the cases represented pure DCIS with no invasive cancer. The DCIS commonly displayed a mixed pattern with micropapillary, cribriform and solid components with the micropapillary type being the rarest, occurring seldom on its own. A continuum of growth with a micropapillary pattern evolving into a cribriform type could be seen in some of the cases. This may explain some of the conflicting information, in the literature, regarding the different architectural types of DCIS. The comedo-pattern of necrosis could be seen in all types of DCIS. We therefore conclude that the study of the determinants of growth pattern in DCIS would be the key to unravelling the diverse, often non-concordant evidence one encounters in the literature.

    Full Text Available Cancer of unknown primary (CUP is the finding of a metastatic cancerous lesion without an established primary source localized within the body. CUP can be of any cancer cell type, however, adenocarcinoma is most often identified by histology. Up to 5% of all malignant diagnoses are classified as CUP. PET is an imaging modality often utilized to distinguish a primary source in the setting of CUP, yet often a primary is never identified. CUP can be further stratified using specific qualifiers as favorable and unfavorable, indicating the potential therapeutic response to treatment regimens. Treatment approach to CUP relies heavily on the cell type identified by histology, the location of the lesion, and the amount of spread within the body. In the typical setting and presentation, per current literature, CUP arises in the 7th decade of life in patients with multiple comorbidities, and often has a poor prognostic value. This case report identifies an atypical presentation of CUP, a 38-year-old Caucasian female with an axillary mobile mass, and no associated systemic symptoms. Biopsy of the node and immunohistochemical staining showed histology consistent with metastatic carcinoma. Mammography, MRI, and PET scan found no evidence of tumor primary or distant metastasis. Further staining confirmed metastatic carcinoma consistent with breast origin, without an established breast primary. As in this case, CUP may present in an atypical manner, warranting a thorough investigation aiming to identify the tumor primary to aid in identification of a proper treatment regimen and approach.

    Purpose Metastatic renal cell carcinoma (RCC), without an identified kidney primary, has been reported rarely. We report a patient with RCC metastatic to bilateral adrenal glands and liver, without an apparent renal primary. We detail the immunohistochemical and molecular studies employed to substantiate the diagnosis of RCC and direct therapy. Methods Histopathologic findings were correlated with imaging data and supplemented by a panel of immunohistochemical stains, as well as tumor sequence analysis. Results Despite the presence of bilateral adrenal masses and lack of tumor within kidney parenchyma, the diagnosis of RCC was substantiated by immunohistochemistry (RCC+/PAX2+/PAX8+/Melan-A−/SF-1− among others) and molecular genetic analysis, harboring mutations in VHL, TP53, KDM5C, and PBRM1. After debulking surgery, based on the diagnosis of RCC and the molecular profile, the patient was treated with a tyrosine kinase inhibitor (sunitinib), resulting in stablilization of disease. Conclusions This case illustrates the role of mutational analysis in carcinomas with rare or unusual presentations, such as metastatic RCC without a renal primary. PMID:26527083

    Phyllodes tumor (PT) is an uncommon fibroepithelial tumor of the breast showing predominately proliferation of the stromal component. The presence of ductal carcinoma in situ (DCIS) or invasive ductal carcinoma is rare, with only a few cases reported in the literature. A retrospective review of a prospectively maintained database was performed. Patients who were treated for PT in 5 hospitals in Hong Kong and Shenzhen, China over a period of 20 years (1997-2016) were evaluated. All pathology slides were reported by specialist pathologists. Patients with coexisting ductal carcinoma were identified. A total of 557 patients were included in this cohort; 363 (65.2%) patients had benign PT, 130 (23.3%) had borderline PT, and 64 (11.5%) had malignant PT. There were 6 (1.1%) patients with coexisting ductal carcinoma in the PT; 5 were DCIS and 1 was invasive ductal carcinoma. The median age was 46.5 years (range, 25-54 years). Ductal carcinoma occurred more frequently in malignant PT than in benign or borderline PT (4.7% vs. 0.6%; P = .02). However, malignant PT was not associated with higher DCIS grade (P = .1). All patients underwent surgery with clear resection margins. After a median follow-up interval of 70 months (range, 2-101 months), all patients remained disease- and recurrence-free. We report 6 additional uncommon cases of ductal carcinoma complicating PT. The presence of ductal carcinoma was not adverse prognosticator as these are usually incidental and situated within the harboring PT. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Localized renal cell carcinoma (RCC is often curable by surgery alone. However, metastatic RCC is generally incurable. In the 1990s, immunotherapy in the form of cytokines was the mainstay of treatment for metastatic RCC. However, responses were seen in only a minority of highly selected patients with substantial treatment-related toxicities. The advent of targeted agents such as vascular endothelial growth factor tyrosine kinase inhibitors VEGF-TKIs and mammalian target of rapamycin (mTOR inhibitors led to a change in this paradigm due to improved response rates and progression-free survival, a better safety profile, and the convenience of oral administration. However, most patients ultimately progress with about 12% being alive at 5 years. In contrast, durable responses lasting 10 years or more are noted in a minority of those treated with cytokines. More recently, an improved overall survival with newer forms of immunotherapy in other malignancies (such as melanoma and prostate cancer has led to a resurgence of interest in immune therapies in metastatic RCC. In this review we discuss the rationale for immunotherapy and recent developments in immunotherapeutic strategies for treating metastatic RCC.

    The great majority of invasive lobular carcinoma (ILC) is estrogen-dependent luminal A type carcinoma but the details of estrogen actions and its intratumoral metabolism have not been well studied compared to invasive ductal carcinoma (IDC). We first immunolocalized estrogen-related enzymes including estrogen sulfotransferase (EST), estrogen sulfatase (STS), 17β-hydroxysteroid dehydrogenase (HSD) 1/2, and aromatase. We then evaluated the tissue concentrations of estrogens in ILC and IDC and subsequently estrogen-responsive gene profiles in these tumors in order to explore the possible differences and/or similarity of intratumoral estrogen environment of these two breast cancer subtypes. The status of STS and 17βHSD1 was significantly lower in ILCs than IDCs (p = 0.022 and p < 0.0001), but that of EST and 17βHSD2 vice versa (p < 0.0001 and p = 0.0106). In ILCs, tissue concentrations of estrone and estradiol were lower than those in IDCs (p = 0.0709 and 0.069). In addition, the great majority of estrogen response genes tended to be lower in ILCs. Among those genes above, FOXP1 was significantly higher in ILCs than in IDCs (p = 0.002). FOXP1 expression was reported to be significantly higher in relapse-free IDC patients treated with tamoxifen. Therefore, tamoxifen may be considered an option of endocrine therapy for luminal A type ILC patients. This is the first study to demonstrate the detailed and comprehensive status of intratumoral production and metabolism of estrogens and the status of estrogen response genes in luminal A-like ILC with comparison to those in luminal A-like IDCs.

    Full Text Available Breast cancer estrogen receptor (ER status is one of the strong additional factors in predicting response of patients towards hormonal treatment. The main aim of this study was to assess the morphological characteristics and proliferative activity using MIB-1(Ki-67 of estrogen receptor negative invasive breast ductal carcinoma (NOS type as well as to correlate these features with clinicopathological data. We also aim to study the expression of c-erbB2 in ER negative breast tumors. High proliferative rate (MIB-1 above 20% was observed in 63 (63.6% of 99 ER negative tumors and that these tumors were associated with high expression of c-erbB2 (57.6%. We observed that MIB-1 is a reliable independent prognostic indicator for ER negative infiltrating ductal carcinoma in this study.

    2016-01-01

    Ductal Carcinoma In Situ (DCIS) is a precursor lesion of Invasive Ductal Carcinoma (IDC) of the breast. Investigating its temporal progression could provide fundamental new insights for the development of better diagnostic tools to predict which cases of DCIS will progress to IDC. We investigate the problem of reconstructing a plausible progression from single-cell sampled data of an individual with synchronous DCIS and IDC. Specifically, by using a number of assumptions derived from the observation of cellular atypia occurring in IDC, we design a possible predictive model using integer linear programming (ILP). Computational experiments carried out on a preexisting data set of 13 patients with simultaneous DCIS and IDC show that the corresponding predicted progression models are classifiable into categories having specific evolutionary characteristics. The approach provides new insights into mechanisms of clonal progression in breast cancers and helps illustrate the power of the ILP approach for similar problems in reconstructing tumor evolution scenarios under complex sets of constraints.

    Background Molecular studies of breast cancer revealed biological heterogeneity of the disease and opened new perspectives for personalized therapy. While multiple gene expression-based systems have been developed, current clinical practice is largely based upon conventional clinical and pathologic criteria. This gap may be filled by development of combined multi-IHC indices to characterize biological and clinical behaviour of the tumours. Digital image analysis (DA) with multivariate statistics of the data opens new opportunities in this field. Methods Tissue microarrays of 109 patients with breast ductal carcinoma were stained for a set of 10 IHC markers (ER, PR, HER2, Ki67, AR, BCL2, HIF-1α, SATB1, p53, and p16). Aperio imaging platform with the Genie, Nuclear and Membrane algorithms were used for the DA. Factor analysis of the DA data was performed in the whole group and hormone receptor (HR) positive subgroup of the patients (n = 85). Results Major factor potentially reflecting aggressive disease behaviour (i-Grade) was extracted, characterized by opposite loadings of ER/PR/AR/BCL2 and Ki67/HIF-1α. The i-Grade factor scores revealed bimodal distribution and were strongly associated with higher Nottingham histological grade (G) and more aggressive intrinsic subtypes. In HR-positive tumours, the aggressiveness of the tumour was best defined by positive Ki67 and negative ER loadings. High Ki67/ER factor scores were strongly associated with the higher G and Luminal B types, but also were detected in a set of G1 and Luminal A cases, potentially indicating high risk patients in these categories. Inverse relation between HER2 and PR expression was found in the HR-positive tumours pointing at differential information conveyed by the ER and PR expression. SATB1 along with HIF-1α reflected the second major factor of variation in our patients; in the HR-positive group they were inversely associated with the HR and BCL2 expression and represented the major factor of

    We report 2 cases of invasive ductal carcinoma of the breast occurring near a phyllodes tumor. The first case was ofa 58- year-old woman who had a tumor in her right breast and visited our hospital. Following a core needle biopsy (CNB), a malignant phyllodes tumor was diagnosed. We performed a lumpectomy for the phyllodes tumor, with 1.5-cm surgical margins. Pathological diagnosis of the resected specimen confirmed the malignant phyllodes tumor. A ductal carcinoma in situ (DCIS) was also discovered near the phyllodes tumor. The second case was of another 58-year-old woman who had a big tumor in her right breast and visited our hospital. CNB resulted in pathological diagnosis ofa benign phyllodes tumor. The tumor was removed by a lumpectomy with 1.5-cm surgical margins. The pathological diagnosis from the resected specimen was borderline phyllodes tumor with invasive ductal carcinoma in the proximity. In both cases, DCIS could not have been diagnosed preoperatively.

    Basal cell carcinoma (BCC), the most common human malignancy, metastasizes in 0.0028% to 0.5% of cases, usually to the lymph nodes, lungs, bones, and skin. After metastatic spread of BCC, survival averages 1 to 2 years. Chemotherapy, radiotherapy, and surgery are treatment options. We describe metastatic basal cell carcinoma to the skin presenting with unilateral upper extremity edema.

    Full Text Available Background/Aim. Most human cancers, including breast one, increase in frequency with aging. The aim of this study was to explore the hypothesis that aging also alters breast cancer biology. Methods. The study included 120 women with primary invasive ductal carcinoma of the breast. We correlated the patients age and diagnosis with the commonly used clinical, pathological factors and newer tumor biomarkers. Immunohistochemical staining was conducted for p53, c-erbB-2, Ki-67, estrogen (ER, progesterone (PR receptors, and angiogenesis. Results. In our study, the patients with axillary lymph node metastases and negative steroid hormone receptors (ER and PR were significantly younger than the patients with nodal involvement and positive hormone receptors. There was also a significant association between the patients age, diagnosis and angiogenesis. No association was found between the patients age and tumor size, histological grade, p53, c-erbB-2, and Ki-67. Conclusion. The results of our study supported only partially the hypothesis that the breast cancer biology is significantly affected by a patient's age.

    Full Text Available Abstract Background It is helpful in planning treatment for patients with ductal carcinoma in situ (DCIS if the size and grade could be reliably predicted from the mammography. The aims of this study were to determine if the type of calcification can be best used to predict histopathological grade from the mammograms, to examine the association of mammographic appearance of DCIS with grade and to assess the correlation between mammographic size and pathological size. Methods Mammographic films and pathological slides of 115 patients treated for DCIS between 1986 and 2000 were reviewed and reclassified by a single radiologist and a single pathologist respectively. Prediction models for the European Pathologist Working Group (EPWG and Van Nuys classifications were generated by ordinal regression. The association between mammographic appearance and grade was tested with the χ2-test. Relation of mammographic size with pathological size was established using linear regression. The relation was expressed by the correlation coefficient (r. Results The EPWG classification was correctly predicted in 68%, and the Van Nuys classification in 70% if DCIS was presented as microcalcifications. High grade was associated with presence of linear calcifications (p Conclusions Prediction of histopathological grade of DCIS presenting as microcalcifications is comparable using the Van Nuys and EPWG classification. There is no strict association of mammographic appearance with histopathological grade. There is a better linear relation between mammographic- and pathological size of DCIS presented as microcalcifications than as a density, although both relations are statistically significant.

    Full Text Available The prevalence of ductal carcinoma in situ (DCIS of the breast has increased substantially after the introduction of breast cancer screening programs, although the clinical effects of early DCIS detection and treatment remain unclear. The standard treatment for DCIS has involved local breast-conserving surgery (BCS followed by radiotherapy (RT or total mastectomy with/without endocrine therapy, and the choice of local treatment is not usually based on clinicopathologic or biological factors. However, we have investigated the effectiveness of local treatment using breast surgery and RT using Surveillance, Epidemiology, and End Results data, and found that the effectiveness of breast surgery was modified by the nuclear grade. Furthermore, breast cancer-specific survival was identical between patients with low-grade DCIS who did and did not undergo surgery. Moreover, we found that RT after BCS for DCIS was only associated with a survival benefit among patients with risk factors for local recurrence, such as nuclear grade, age, and tumor size. Ongoing clinical trials and translational research have attempted to develop a treatment strategy that prevents the overdiagnosis and overtreatment of low-risk DCIS, as well as a biology-based treatment strategy for using targeted therapy. Therefore, to develop a tailored treatment strategy for DCIS, we need to identify molecular and biological classifications based on the results from translational research, national databases, and clinical trials.

    DCIS (Ductal carcinoma in situ) constitutes 15,2% of breast cancers. Conservative surgery coupled with adjuvant radiotherapy is often recommended. The rate of revision surgery is high, from 30 to 60%. The concern is a high quality resection within clear margins with a satisfactory aesthetic result. The objective of this review is to precise the place of oncoplastic surgery in DCIS care. Among risk factors of recurrence, tumoral invasion of surgical margins is capital. In histology, clear margins usually adopted for DCIS are 2mm, even though there is no international consensus. Recent studies show that a 10mm limit would be better. Aesthetic damage caused by surgery, often increased by radiotherapy, has a negative impact on women quality of life: oncoplastic surgery may minimize it. Techniques of plastic surgery, arranged into level 1 and 2, allow pushing back conservative treatment limits by removing a larger tumor with clear margins. Often used in invasive cancers, few data exist regarding oncoplastic surgery and DCIS. It allows to increase the dimensions of surgical resection by 20% and to decrease positive margins significantly therefore the rate of revision surgeries. Patients are satisfied with it. Specific indications need to be clarified according to age, size and "comedonecrosis" presence. Oncoplastic surgery should be developed in DCIS specific care. Copyright © 2015 Elsevier Masson SAS.

    Ductal carcinoma in situ (DCIS) is often considered as the precursor of invasive breast cancer, and the risk of DCIS progression to IBC has been estimated based on the evaluation of pathological features, among which the architectural subtype is the most common one. In this study, multiphoton microscopy (MPM) is applied to identify three different architectural subtypes of DCIS (solid, cribriform and comedo). It is found that MPM has the capability to visualize the proliferating pattern of tumor cells, the presence of intraluminal necrosis and the morphology of basement membrane, which are all taken into account in subtyping DCIS. In addition, MPM also can be used to quantify the cellular metabolism, for quantitatively identifying tumor staging during tumor progression. This result highlights the potential of MPM as an advanced technique to assess the pathological characters of the breast tumor in real-time and reflect the degree of tumor progression in vivo, by integrating into the intra-fiberoptic ductoscopy or transdermal biopsy needle.

    Nearly 20% of all breast cancer cases are ductal carcinoma in situ (DCIS), with over 60,000 cases diagnosed each year. Many of these cases would never cause clinical symptoms or threaten the life of the woman; however, it is currently impossible to distinguish which lesions will progress to invasive disease from those that will not. DCIS is generally associated with an excellent prognosis regardless of the treatment pathway, but there is variation in treatment aggressiveness that seems to exceed the medical uncertainty associated with DCIS management. Therefore, it would seem that a significant proportion of women with DCIS receive more extensive treatment than is needed. This overtreatment of DCIS is a growing concern among the breast cancer community and has implications for both the patient (via adverse treatment-related effects, as well as out-of-pocket costs) and society (via economic costs and the public health and environmental harm resulting from health care delivery). This article discusses DCIS treatment pathways and their implications for patients and society and calls for further research to examine the factors that are leading to such wide variation in treatment decisions.

    Cullin1 (Cul1) is a matrix degrading enzyme known to be involved in the remodelling of extracellular matrix proteins. This enzyme has recently been reported to play a key role in tumour progression and its presence is associated with poor clinical outcome for several different types of tumours. 159 patients diagnosed with invasive ductal carcinoma between 2000 and 2005 were studied. Cul1 expression was analysed by immunohistochemical staining on a tissue microarray. The relationship between Cul1 expression and clinicopathological parameters was evaluated. Tumour expression of Cul1 was correlated with prognostic factors such as high histological grade and p53 expression, and was also linked to negative ER and positive HER2 as therapeutic markers (all pCul1 expression in both univariate and multivariate analyses (all pCul1 expression was significantly associated with high-grade tumours and poor prognosis, suggesting that it may play a role in breast tumour progression. Cul1 expression may therefore be crucial for the prediction of disease outcome in breast cancer patients.

  3. Modeling ductal carcinoma in situ: a HER2-Notch3 collaboration enables luminal filling.

    A large fraction of ductal carcinoma in situ (DCIS), a non-invasive precursor lesion of invasive breast cancer, overexpresses the HER2\\/neu oncogene. The ducts of DCIS are abnormally filled with cells that evade apoptosis, but the underlying mechanisms remain incompletely understood. We overexpressed HER2 in mammary epithelial cells and observed growth factor-independent proliferation. When grown in extracellular matrix as three-dimensional spheroids, control cells developed a hollow lumen, but HER2-overexpressing cells populated the lumen by evading apoptosis. We demonstrate that HER2 overexpression in this cellular model of DCIS drives transcriptional upregulation of multiple components of the Notch survival pathway. Importantly, luminal filling required upregulation of a signaling pathway comprising Notch3, its cleaved intracellular domain and the transcriptional regulator HES1, resulting in elevated levels of c-MYC and cyclin D1. In line with HER2-Notch3 collaboration, drugs intercepting either arm reverted the DCIS-like phenotype. In addition, we report upregulation of Notch3 in hyperplastic lesions of HER2 transgenic animals, as well as an association between HER2 levels and expression levels of components of the Notch pathway in tumor specimens of breast cancer patients. Therefore, it is conceivable that the integration of the Notch and HER2 signaling pathways contributes to the pathophysiology of DCIS.

    Ductal carcinoma in situ (DCIS) is a noninvasive precursor lesion to invasive breast carcinoma. We still have no understanding on why only some DCIS lesions evolve to invasive cancer whereas others appear not to do so during the life span of the patient. Here, we performed full exome (tumor vs. matching normal), transcriptome, and methylome analysis of 30 pure high-grade DCIS (HG-DCIS) and 10 normal breast epithelial samples. Sixty-two percent of HG-DCIS cases displayed mutations affecting cancer driver genes or potential drivers. Mutations were observed affecting PIK3CA (21% of cases), TP53 (17%), GATA3 (7%), MLL3 (7%) and single cases of mutations affecting CDH1, MAP2K4, TBX3, NF1, ATM, and ARID1A. Significantly, 83% of lesions displayed numerous large chromosomal copy number alterations, suggesting they might precede selection of cancer driver mutations. Integrated pathway-based modeling analysis of RNA-seq data allowed us to identify two DCIS subgroups (DCIS-C1 and DCIS-C2) based on their tumor-intrinsic subtypes, proliferative, immune scores, and in the activity of specific signaling pathways. The more aggressive DCIS-C1 (highly proliferative, basal-like, or ERBB2(+)) displayed signatures characteristic of activated Treg cells (CD4(+)/CD25(+)/FOXP3(+)) and CTLA4(+)/CD86(+) complexes indicative of a tumor-associated immunosuppressive phenotype. Strikingly, all lesions showed evidence of TP53 pathway inactivation. Similarly, ncRNA and methylation profiles reproduce changes observed postinvasion. Among the most significant findings, we observed upregulation of lncRNA HOTAIR in DCIS-C1 lesions and hypermethylation of HOXA5 and SOX genes. We conclude that most HG-DCIS lesions, in spite of representing a preinvasive stage of tumor progression, displayed molecular profiles indistinguishable from invasive breast cancer. ©2015 American Association for Cancer Research.

    Full Text Available Objective. We report a rare and unusual case of bronchial carcinoma presenting with symptoms of complications of sinonasal disease. Case Report. A 66-year-old lady was referred with a 1-week history of progressive ocular pain, chemosis, and visual disturbance. Computed tomography of the paranasal sinuses revealed frontal and ethmoidal sinus opacification with orbital involvement consistent with a diagnosis of orbital cellulitis secondary to sinusitis. Surgical exploration revealed that the sinuses and right orbit were filled with soft tissue and subsequent histopathological examination of the biopsies indicating metastases from an adenosquamous bronchial carcinoma. Further imaging revealed a large, asymptomatic, bronchial primary with deposits in the brain and liver. The advanced presentation of the disease limited treatment to best supportive care. Conclusion. Orbital cellulitis and sinonasal malignancies have a similar pattern of clinical presentation, posing a potential diagnostic pitfall. There are only two previously reported cases of metastatic lung carcinoma in the frontal sinus with 15 cases of sinonasal tract involvement reported overall. There are no reported cases of adenosquamous carcinoma in the sinonasal tract.

The aim of this study was to evaluate and describe the computed tomography (CT features of ACC and compare the results with pancreatic ductal adenocarcinoma (DAC for improving preoperative diagnosis. The control group consisted of 34 patients with DAC collected from the pathology electronic database. The CT imaging from nine patients with pathologically confirmed ACC was retrospectively reviewed. Two radiologists independently assessed the tumor location, size, texture, and enhancement patterns. We found that 64.3% (9/14 of ACC tumors were homogeneous and 35.7% (5/14 had necrosis. The percentage of common bile duct and pancreatic ductal dilation was 14.3% (2/14 and 7.1% (1/14, respectively. The mean size of ACC was 50.1±24.2 mm. The mean attenuation of ACC was 35.4±3.9 Hounsfield unit (HU before enhancement, 73.1±42.9 HU in arterial phase, and 71.8±15.6 HU in port venous phase. It is difficult to distinguish ACC from DAC preoperatively only based on CT findings. However, compared with DAC, we found that ACC tumors are likely to be larger and contain more heterogeneous intratumoral necrotic hypovascular regions, and less pancreatic ductal and common biliary dilation.

    Full Text Available To compare the lesion distribution and the extent of the disease in ductal and lobular carcinomas of the breast, we studied 586 ductal and 133 lobular consecutive cancers. All cases were documented on large-format histology slides. The invasive component of ductal carcinomas was unifocal in 63.3% (371/586, multifocal in 35.5% (208/586, and diffuse in 1.2% (7/586 of the cases. The corresponding figures in the lobular group were 27.8% (37/133, 45.9% (61/586, and 26.3% (35/133, respectively. When the distribution of the in situ and invasive component in the same tumors was combined to give an aggregate pattern, the ductal carcinomas were unifocal in 41.6% (244/586, multifocal in 31.6% (185/586, and diffuse in 26.8% (157/586 of the cases. The corresponding figures in the lobular category were 15.0% (20/133, 54.2% (72/133, and 30.8% (41/133, respectively. Ductal cancers were extensive in 45.7% (268/586, lobular in 65.4% (87/133 of the cases. All these differences were statistically highly significant (. While the histological tumor type itself (ductal versus lobular did not influence the lymph node status, multifocal and diffuse distribution of the lesions were associated with significantly increased risk of lymph node metastases in both ductal and lobular cancers.

    The aim of this analysis was to determine the risk of malnutrition and the prognostic value of nutritional intervention in patients affected by pancreatic ductal adenocarcinoma (PDAC) undergoing chemotherapy. Clinical-pathological and nutritional data were correlated with overall survival (OS) using a Cox model. Nutritional status was determined by Malnutrition Universal Screening Tool (MUST), body mass index, weight loss in the past 6 months, presence of nutrition-related symptoms, and current energy intake. Nutritional intervention included appropriate individual dietary counseling. Data from 109 patients were gathered (median age 63 years). The majority of patients (64.2%) presented a MUST value of ≥ 2, corresponding to a high risk of malnutrition. At multivariate analysis for OS in locally advanced and metastatic PDAC patients, the time between the diagnosis and the nutritional intervention (HR 2.22, p = 0.017), the performance status (HR 1.38, p = 0.075), the surgery of the primary (HR 5.89, p = 0.005), and the response to the first line (HR 5.9, p = 0.03) were independent significant predictors of outcome. Furthermore, a weight gain > 2% from the baseline weight was correlated with the time between the diagnosis and the nutritional intervention (p = 0.021): in patients receiving a nutritional support within 3 months from diagnosis, a 2% weight gain was associated with a 2-year OS benefit (50.3% vs. 33.0%, p = 0.04). This analysis suggests that the early nutritional support may contribute to influence the prognosis of patients affected by advanced PDAC undergoing chemotherapy.

    Ductal carcinoma in situ (DCIS) is a pre-invasive malignancy detected with an increasing frequency through screening mammography. One of the primary aims of therapy is to prevent local recurrence, as in situ or as invasive carcinoma, the latter arising in half of the recurrent cases. Reliable biomarkers predictive of its association with recurrence, particularly as invasive disease, are however lacking. In this study, we perform a meta-analysis of 26 studies which report somatic copy number aberrations (SCNAs) in 288 cases of 'pure' DCIS and 328 of DCIS associated with invasive carcinoma, along with additional unmatched cases of 145 invasive carcinoma of ductal/no special type (IDC) and 50 of atypical ductal hyperplasia (ADH). SCNA frequencies across the genome were calculated at cytoband resolution (UCSC genome build 19) to maximally utilize the available information in published literature. Fisher's exact test was used to identify significant differences in the gain-loss distribution in each cytoband in different group comparisons. We found synchronous DCIS to be at a more advanced stage of genetic aberrations than pure DCIS and was very similar to IDC. Differences in gains and losses in each disease process (i.e. invasive or in situ) at each cytoband were used to infer evidence of selection and conservation for each cytoband and to define an evolutionary conservation scale (ECS) as a tool to identify and distinguish driver SCNA from the passenger SCNA. Using ECS, we have identified aberrations that show evidence of selection from the early stages of neoplasia (i.e. in ADH and pure DCIS) and persist in IDC; we postulate these to be driver aberrations and that their presence may predict progression to invasive disease.

    Full Text Available Background As a kind of rare tumor, metastatic pituitary carcinoma is very difficult to diagnose clinically and is easy to be misdiagnosed. This article aims to discuss the clinical manifestations and histopathological features of this tumor. Methods The clinical presentations, histopathological features and immunophenotype were studied in one case of poorly differentiated lung adenocarcinoma metastatic to pituitary gland, and related literature was reviewed. Results A 47-year-old woman mainly presented with faint, headache and blurred vision. CT scan demonstrated abnormal signals in suprasellar cistern. During the resection, the tumor could be seen locating in sellar region, the size of which was about 2 cm × 1 cm × 1 cm. Histopathological examination revealed that the structure of pituitary gland was damaged and the tumor was composed of atypical round or oval cells arranged in nest or glandular patterns, in which a number of enlarged plump tumor cells contained abundant eosinophilic cytoplasm with eccentrical caryogenesis. The immunohistochemistry showed that epithelial membrane antigen (EMA, pan cytokeratin (PCK, thyroid transcription factor-1 (TTF-1 and cytokeratin 7 (CK7 were positive in tumor cells with Ki-67 labeling index being 15%, but chromogranin (CgA, cancer embryo antigen (CEA, human chorionic gonadotropin (hCG, placental alkaline phosphatase (PLAP, CD117, leukocyte common antigen (LCA, CD30, anaplastic lymphoma kinase-1 (ALK-1 were negative in tumor cells. After operation the patient received treatment with levothyroxine sodium and γ knife, but died 4 months later. Conclusion Histopathological examination and immunohistochemistry can confirm the diagnosis of metastatic pituitary carcinoma and locate the primary lesion. Postoperative comprehensive therapy is necessary.

Methods Clinicopathologic features, overall survival (OS, and recurrence/metastasis-free survival (RFS were compared between 2,202 patients with IDC and 215 patients with ILC. Results ILC was significantly more likely to be associated with a favorable phenotype, but the incidence of contralateral breast cancer was higher for ILC patients than for IDC patients (8.4% vs. 3.9%; P =0.001. The frequencies of recurrence/metastasis (P = 0.980 and death (P = 0.064 were similar among patients with IDC and patients with ILC after adjustment for tumor size and nodal status. The median follow-up was 42.8 months. Conclusions Chinese women with ILCs do not have better clinical outcomes than their counterparts with IDC. Management decisions should be based on individual patient and tumor biologic characteristics, and not on lobular histology.

    Full Text Available Abstract Background Lysine-specific demethylase1 (LSD1 is a nuclear protein which belongs to the aminooxidase-enzymes playing an important role in controlling gene expression. It has also been found highly expressed in several human malignancies including breast carcinoma. Our aim was to detect LSD1 expression also in pre-invasive neoplasias of the breast. In the current study we therefore analysed LSD1 protein expression in ductal carcinoma in situ (DCIS in comparison to invasive ductal breast cancer (IDC. Methods Using immunohistochemistry we systematically analysed LSD1 expression in low grade DCIS (n = 27, intermediate grade DCIS (n = 30, high grade DCIS (n = 31 and in invasive ductal breast cancer (n = 32. SPSS version 18.0 was used for statistical analysis. Results LSD1 was differentially expressed in DCIS and invasive ductal breast cancer. Interestingly, LSD1 was significantly overexpressed in high grade DCIS versus low grade DCIS. Differences in LSD1 expression levels were also statistically significant between low/intermediate DCIS and invasive ductal breast carcinoma. Conclusions LSD1 is also expressed in pre-invasive neoplasias of the breast. Additionally, there is a gradual increase of LSD1 expression within tumour progression from pre-invasive DCIS to invasive ductal breast carcinoma. Therefore upregulation of LSD1 may be an early tumour promoting event.

Main outcome measures included patient demographics, lesion size, location of metastases, histologic subtype, recurrence rate, time between primary tumor diagnosis and metastasis, perineural invasion, treatment modalities, and survival from time of metastasis. The median tumor size at largest dimension was 3.3 cm (range, 1.9-11.5 cm), and 6 of 10 patients had at least 1 local recurrence before metastasis (range, 0-2 recurrences). The most common sites of metastasis included the ipsilateral parotid gland (n = 6) and cervical lymph nodes (n = 5). Histologic subtypes included infiltrative (n = 5), basosquamous (n = 2), nodular (n = 1), and mixed (n = 1). The median time from primary tumor diagnosis to metastasis was 7.5 years (range, 0-13). The median survival time from diagnosis of metastasis to last documented encounter or death was 5.3 years (range, 7 months-22.8 years). Treatment regimens included surgical excision, radiotherapy, and hedgehog inhibitors. Based on our findings, the following features may be markers of high risk orbitofacial basal cell carcinoma: 1) increasing tumor size, 2) local recurrence of the primary tumor, 3) aggressive histologic subtype, and 4) perineural invasion. Screening should include close observation of the primary site and tissues in the distribution of regional lymphatics, particularly the parotid gland and cervical lymph nodes.

    As a result of activation of transcription factors engaged in epithelial-mesenchymal transition (EMT), such as Twist, inhibition of epithelial markers and an increased expression of mesenchymal markers are observed. One of the specific markers of cancer-associated fibroblasts is podoplanin (PDPN) - a mucin-type membrane glycoprotein. The aim of this work was to study the localisation and intensity of expression of Twist and PDPN on the mRNA and protein level in cases of invasive ductal breast carcinoma (IDC), and its association with patients' clinico-pathological data. The study included archival material in a form of 80 paraffin IDC blocks and 11 IDC fragments frozen in liquid nitrogen. Immunohistochemical expression of Twist and PDPN was evaluated using light microscope and semiquantitative scale for evaluation of nuclear expression or immunoreactive scale (IRS) for evaluation of cytoplasmic expression. Material was isolated from frozen IDC fragments using laser micro-dissection (from cancer and stromal cells, separately) and was used to perform real-time PCR. Twist expression was higher in stromal cells in comparison to cancer cells. Analysis of patients' survival rate showed, that higher expression of Twist in cancer cells was associated with shorter overall survival time and shorter event-free survival time. The expression of PDPN was also higher in stromal cells in comparison with cancer cells. In addition, positive correlation was observed between expression of Twist and PDPN in stromal cells of IDC (r=0.267; p<0.05). The relationship between the higher expression of Twist in both cancer and stromal cells and shorter patients' survival indicates Twist as a potential useful prognostic marker in IDC. Positive correlation of Twist and PDPN expression may indicate the role of PDPN in EMT in IDC. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

    The natural history of ductal carcinoma in situ (DCIS) remains uncertain. The risk factors for the development of invasive cancer in unresected DCIS are unclear. Women diagnosed with DCIS on needle biopsy after 1997 who did not undergo surgical resection for ≥1 year after diagnosis were identified by breast centres and the cancer registry and outcomes were reviewed. Eighty-nine women with DCIS diagnosed 1998-2010 were identified. The median age at diagnosis was 75 (range 44-94) years with median follow-up (diagnosis to death, invasive disease or last review) of 59 (12-180) months. Twenty-nine women (33%) developed invasive breast cancer after a median interval of 45 (12-144) months. 14/29 (48%) with high grade, 10/31 (32%) with intermediate grade and 3/17 (18%) with low grade DCIS developed invasive cancer after median intervals of 38, 60 and 51 months. The cumulative incidence of invasion was significantly higher in high grade DCIS than other grades (p = .0016, log-rank test). Invasion was more frequent in lesions with calcification as the predominant feature (23/50 v. 5/25; p = .042) and in younger women (p = .0002). Endocrine therapy was associated with a lower rate of invasive breast cancer (p = .048). High cytonuclear grade, mammographic microcalcification, young age and lack of endocrine therapy were risk factors for DCIS progression to invasive cancer. Surgical excision of high grade DCIS remains the treatment of choice. Given the uncertain long-term natural history of non-high grade DCIS, the option of active surveillance of women with this condition should be offered within a clinical trial. Crown Copyright © 2018.

    Retrospective analysis of breast cancer imaging methods is a common tool for evaluating the effectiveness of ultrasound and mammography regarding ductal carcinoma in situ (DCIS). No large number subpopulation of pure DCIS has been reported. It is however known that mammography and ultrasound underestimate tumor dimension with increasing tumor size. We aimed to quantify this discrepancy. This retrospective analysis reviewed the ultrasound and mammography data from 173 patients with DCIS at the University of Cologne - Department of Gynecology and Obstetrics between the years 2007 and 2010. Of these 173 patients, 34 fulfilled the DCIS analysis requirements and were evaluated in this study. Overall, ultrasound underestimated tumor size 79.4% of the time, while overestimating only 20.6% of the time. Mammography underestimated tumor size in 50%, overestimated in 38.2%, correctly estimating in 11.8%. Over and underestimation distributions differed drastically above and a cut-off point of ≤2 cm actual tumor size, with a significant shift toward severe underestimation by both methods above a tumor size of 2 cm. DCIS misestimation was defined as the absolute value of the difference between actual tumor size and pre-surgical measurement by an imaging method. Mean DCIS size misestimation (actual tumor size ≤2 cm) was 3 mm for ultrasound and 6.2 mm for mammography. We support previous findings that ultrasound and mammography lose accuracy with increasing tumor size. Nonetheless, ultrasound may be more useful in estimation of DCIS size for tumors ≤2 cm than previously expected. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

    Purpose: To examine, in a large, population-based cohort of women, the risk factors for recurrence after mastectomy for pure ductal carcinoma in situ (DCIS) and to identify which patients may benefit from postmastectomy radiation therapy. Methods and Materials: Data were analyzed for 637 subjects with pure DCIS, diagnosed between January 1990 and December 1999, treated initially with mastectomy. Locoregional relapse (LRR), breast cancer-specific survival, and overall survival were described using the Kaplan-Meier method. Reported risk factors for LRR (age, margins, size, Van Nuys Prognostic Index, grade, necrosis, and histologic subtype) were analyzed by univariate (log-rank) and multivariate (Cox modeling) methods. Results: Median follow-up was 12.0 years. Characteristics of the cohort were median age 55 years, 8.6% aged ≤40 years, 30.5% tumors >4 cm, 42.5% grade 3 histology, 37.7% multifocal disease, and 4.9% positive margins. At 10 years, LRR was 1.0%, breast cancer-specific survival was 98.0%, and overall survival was 90.3%. All recurrences (n=12) involved ipsilateral chest wall disease, with the majority being invasive disease (11 of 12). None of the 12 patients with recurrence died of breast cancer; all were successfully salvaged (median follow-up of 4.4 years). Ten-year LRR was higher with age ≤40 years (7.5% vs 1.5%; P=.003). Conclusion: Mastectomy provides excellent locoregional control for DCIS. Routine use of postmastectomy radiation therapy is not justified. Young age (≤40 years) predicts slightly higher LRR, but possibly owing to the small number of cases with multiple risk factors for relapse, a subgroup with a high risk of LRR (ie, approximately 15%) was not identified.

    Purpose: To determine outcomes of accelerated partial-breast irradiation (APBI) with MammoSite in the treatment of ductal carcinoma in situ (DCIS) after breast-conserving surgery. Methods and Materials: We conducted a prospective, multicenter trial between 2003 and 2009. Inclusion criteria included age >18 years, core needle biopsy diagnosis of DCIS, and no prior breast cancer history. Patients underwent breast-conserving surgery plus MammoSite placement. Radiation was given twice daily for 5 days for a total of 34 Gy. Patients were evaluated for development of toxicities, cosmetic outcome, and ipsilateral breast tumor recurrence (IBTR). Results: A total of 41 patients (42 breasts) completed treatment in the study, with a median follow up of 5.3 years. Overall, 28 patients (68.3%) experienced an adverse event. Skin changes and pain were the most common adverse events. Cosmetic outcome at 6 months was judged excellent/good by 100% of physicians and by 96.8% of patients. At 12 months, 86.7% of physicians and 92.3% of patients rated the cosmetic outcome as excellent/good. Overall, 4 patients (9.8%) developed an IBTR (all DCIS), with a 5-year actuarial rate of 11.3%. All IBTRs were outside the treatment field. Among patients with IBTRs, the mean time to recurrence was 3.2 years. Conclusions: Accelerated partial-breast irradiation using MammoSite seems to provide a safe and cosmetically acceptable outcome; however, the 9.8% IBTR rate with median follow-up of 5.3 years is concerning. Prospective randomized trials are necessary before routine use of APBI for DCIS can be recommended.

    Full Text Available Abstract Background The number of breast cancer patients diagnosed with ductal carcinoma in situ (DCIS continues to grow. Laboratory and clinical data indicate that DCIS can progress to invasive disease. Carbohydrate-mediated cell-cell adhesion and tumor-stroma interaction play crucial roles in tumorigenesis and tumor aggressive behavior. Breast carcinogenesis may reflect quantitative as well as qualitative changes in oligosaccharide expression, which may provide a useful tool for early detection of breast cancer. Because tumor-associated carbohydrate antigens (TACA are implicated in tumor invasion and metastasis, the purpose of this study was to assess the expression of selected TACA by lectin histochemistry on DCIS specimens from the archival breast cancer tissue array bank of the University of Arkansas for Medical Sciences. Methods For detection of TACA expression, specimens were stained with Griffonia simplicifolia lectin-I (GS-I and Vicia vilosa agglutinin (VVA. We studied associations of lectin reactivity with established prognostic factors, such as tumor size, tumor nuclear grade, and expression of Her-2/neu, p53 mutant and estrogen and progesterone receptors. Results We observed that both lectins showed significant associations with nuclear grade of DCIS. DCIS specimens with nuclear grades II and III showed significantly more intense reactivity than DCIS cases with nuclear grade I to GS-1 (Mean-score chi-square = 17.60, DF = 2; P = 0.0002 and VVA (Mean-score chi-square = 15.72, DF = 2; P = 0.0004. Conclusion The results suggest that the expression of VVA- and GS-I-reactive carbohydrate antigens may contribute to forming higher grade DCIS and increase the recurrence risk.

    The aim of this study was to determine whether deep features extracted from digital mammograms using a pretrained deep convolutional neural network are prognostic of occult invasive disease for patients with ductal carcinoma in situ (DCIS) on core needle biopsy. In this retrospective study, digital mammographic magnification views were collected for 99 subjects with DCIS at biopsy, 25 of which were subsequently upstaged to invasive cancer. A deep convolutional neural network model that was pretrained on nonmedical images (eg, animals, plants, instruments) was used as the feature extractor. Through a statistical pooling strategy, deep features were extracted at different levels of convolutional layers from the lesion areas, without sacrificing the original resolution or distorting the underlying topology. A multivariate classifier was then trained to predict which tumors contain occult invasive disease. This was compared with the performance of traditional "handcrafted" computer vision (CV) features previously developed specifically to assess mammographic calcifications. The generalization performance was assessed using Monte Carlo cross-validation and receiver operating characteristic curve analysis. Deep features were able to distinguish DCIS with occult invasion from pure DCIS, with an area under the receiver operating characteristic curve of 0.70 (95% confidence interval, 0.68-0.73). This performance was comparable with the handcrafted CV features (area under the curve = 0.68; 95% confidence interval, 0.66-0.71) that were designed with prior domain knowledge. Despite being pretrained on only nonmedical images, the deep features extracted from digital mammograms demonstrated comparable performance with handcrafted CV features for the challenging task of predicting DCIS upstaging.

    Background: The aim of this analysis was to ascertain whether uni-dimensional measurement of mammographic microcalcification, the product of bi-dimensional measurement, calcification morphology, and pathological grade are helpful in predicting successful single therapeutic wide local excision (WLE) of ductal carcinoma in situ (DCIS). Methods: The study group comprised 505 patients whose mammograms showed the DCIS as calcification, and in whom a non-operative diagnosis had been obtained and WLE attempted. The extents of mammographic calcifications was measured in two planes at 90{sup o} on the oblique view, the appearances classified as comedo, granular, or punctate. DCIS was graded using cyto-nuclear characteristics. Results: Three hundred and forty-two patients had a successful first WLE and 163 patients had further surgery. A uni-dimensional measurement of <35 mm and a bi-dimensional product of <800 mm{sup 2} were associated with successful excision (69 versus 54%, p = 0.02 and 70 versus 27%, p = 0.0001, respectively). Mammographic calcification morphology and histological grade did not influence the likelihood of a successful first WLE. For high-grade DCIS, the upper limit of the bi-dimensional product associated with successful WLE was 800 mm{sup 2} (69 versus 24%, p = 0.0003). In contrast, for non-high-grade DCIS, the cut-off was 400 mm{sup 2} (73 versus 33%, p = 0.01). Analyses based on mammographic calcification morphology gave similar findings. Conclusion: The mammographic bi-dimensional product is a powerful predictor of successful WLE of DCIS when combined with histological grade and/or calcification morphology.

    Hypofractionated radiotherapy (RT) in the setting of early invasive breast cancer has been shown to have similar local control rates and cosmetic outcomes as conventionally fractionated RT. This study compares ipsilateral recurrence rates between hypofractionated and conventional RT, with and without a boost. The effect of hypofractionated RT and chest wall separation (CWS) on cosmetic outcome was also assessed. All patients with ductal carcinoma in situ (DCIS) treated between 1998 and 2012 across two sites of a single cancer institution were retrospectively studied. Patients were analysed according to those receiving conventional RT (≤2 Gy per fraction) and those receiving hypofractionated RT (>2 Gy per fraction), as well as the presence or absence of a tumour bed boost. Data were collected through electronic medical records and local cancer registry. Cosmetic outcome was scored by physicians on a four-point scale during clinical follow-up appointments. One hundred and ninety-seven patients were treated for DCIS during the study period. One hundred and forty-one were treated with conventional RT, and 56 with hypofractionated RT. After a median follow up of 4.4 years, there were 12 ipsilateral recurrences, of which seven were invasive disease and five DCIS. Ten recurrences occurred in patients who received conventional RT (7.1% recurrence rate) and two in those who received hypofractionated RT (3.6% recurrence rate) (P = 0.48). Cosmetic outcomes were not significantly different between conventional and hypofractionated RT (P = 0.06). Hypofractionation represents a suitable alternative for treating DCIS in the absence of randomised data.

    In humans, two main types of membrane melatonin receptors have been identified, MT1 and MT2. Expression of MT1 in neoplastic cells seems to increase the efficacy of melatonin's oncostatic activity. The purpose of this study was to determine the distribution and the intensity of MT1 expression in breast cancer cells and to correlate it with clinicopathological factors. Immunohistochemical studies (IHC) were conducted on 190 cases of invasive ductal breast carcinomas (IDC) and molecular studies were performed on 29 cases of frozen tumor fragments and selected breast cancer cell lines. Most of the studied tumors manifested a membranous/cytoplasmic IHC expression of MT1. In IDC, the MT1 expression was higher than in fibrocystic breast disease. MT1 expression was higher in estrogen receptor positive (ER+) and HER2 positive (HER2+) tumors. Triple negative tumors (TN) manifested the lowest MT1 expression level. The lowest MT1 protein expression level was noted in the TN breast cancer cell line MDA-MB-231 compared with ER+ cell lines MCF-7 and SK-BR-3. MT1 mRNA expression was negatively correlated with the malignancy grade of the studied IDC cases. Moreover, higher MT1 expression was associated with patients' longer overall survival (OS) in the group of ER+ breast cancers and treated with tamoxifen. Multivariate analysis indicated that MT1 was an independent prognostic factor in the ER+ tumors for OS and event-free survival in the ER+ tumors. The results of this study may point to a potential prognostic and therapeutic significance of MT1 in IDC. © 2013 John Wiley & Sons A/S. Published by Blackwell Publishing Ltd.

    Reducing the overdiagnosis and overtreatment associated with ductal carcinoma in situ (DCIS) requires accurate prediction of the invasive potential at cancer screening. In this work, we investigated the utility of pre-operative histologic and mammographic features to predict upstaging of DCIS. The goal was to provide intentionally conservative baseline performance using readily available data from radiologists and pathologists and only linear models. We conducted a retrospective analysis on 99 patients with DCIS. Of those 25 were upstaged to invasive cancer at the time of definitive surgery. Pre-operative factors including both the histologic features extracted from stereotactic core needle biopsy (SCNB) reports and the mammographic features annotated by an expert breast radiologist were investigated with statistical analysis. Furthermore, we built classification models based on those features in an attempt to predict the presence of an occult invasive component in DCIS, with generalization performance assessed by receiver operating characteristic (ROC) curve analysis. Histologic features including nuclear grade and DCIS subtype did not show statistically significant differences between cases with pure DCIS and with DCIS plus invasive disease. However, three mammographic features, i.e., the major axis length of DCIS lesion, the BI-RADS level of suspicion, and radiologist's assessment did achieve the statistical significance. Using those three statistically significant features as input, a linear discriminant model was able to distinguish patients with DCIS plus invasive disease from those with pure DCIS, with AUC-ROC equal to 0.62. Overall, mammograms used for breast screening contain useful information that can be perceived by radiologists and help predict occult invasive components in DCIS.

    Trace elements play an important role in a number of biological processes. Astaxanthin, a carotoid pigment found in certain marine plant and animals, has shown anti cancer and anti free radical properties. This work intended to understand the effect of Astaxanthin in breast cancer (invasive ductal carcinoma) by using micro-PIXE method. For this aim the concentration of trace elements were compared in healthy, cancerous and cancer treated with astaxanthin in the breast and liver tissues of breast cancer bearing mice, using proton induced X-ray emission. Materials and Methods: Proton induced X-ray emission was used In a study intending to compare the concentration of trace elements in breast and liver tissues of mice bearing tumor, three groups of mice: healthy, cancerous, and cancerous treated by astaxanthin, were considered. Astaxanthin was supplied from Research Institute of women, Alzahra University. Results: Comparing the untreated tumor tissue, treatment with Astaxanthm significantly decreased the amount Fe, P, S, and Ca elements level in tumor tissue of the breast cancer. It is also found that the concentrations of those elements in liver of the untreated mice and the liver of treated mice with astaxanthin were fairly equal. Astaxanthln significantly decrease the accumulation of elements in the site of tumor, and caused the breast cancer cell membrane to lose their desire to collect the elements from healthy tissues. Conclusion: The micro -PIXE technique could calculate elemental concentrations in tissues. Changes in metallic elements may affect microenvironment and cell functions, which might led lead to cell degeneration or death, the results shows that astaxanthin reduces vital element concentration in tumor site, thus it could be used as an anti tumor agent.

    Accelerated whole-breast radiotherapy (RT) with tumor bed boost in the treatment of early invasive breast cancer has demonstrated equivalent local control and cosmesis when compared with standard RT. Its efficacy in the treatment of ductal carcinoma in situ (DCIS) remains unknown. Patients treated for DCIS with lumpectomy and negative margins were eligible for 2 consecutive hypofractionated whole-breast RT clinical trials. The first trial (New York University [NYU] 01-51) prescribed to the whole breast 42 Gy (2.8 Gy in 15 fractions) and the second trial (NYU 05-181) 40.5 Gy (2.7 Gy in 15 fractions) with an additional daily boost of 0.5 Gy to the surgical cavity. Between 2002 and 2009, 145 DCIS patients accrued, 59 to the first protocol and 86 to the second trial. Median age was 56 years and 65% were postmenopausal at the time of treatment. Based on optimal sparing of normal tissue, 79% of the patients were planned and treated prone and 21% supine. At 5 years' median follow-up (60 months; range 2.6-105.5 months), 6 patients (4.1%) experienced an ipsilateral breast recurrence in all cases of DCIS histology. In 3/6 patients, recurrence occurred at the original site of DCIS and in the remaining 3 cases outside the original tumor bed. New contralateral breast cancers arose in 3 cases (1 DCIS and 2 invasive carcinomas).

    Background: Accelerated whole-breast radiotherapy (RT) with tumor bed boost in the treatment of early invasive breast cancer has demonstrated equivalent local control and cosmesis when compared with standard RT. Its efficacy in the treatment of ductal carcinoma in situ (DCIS) remains unknown. Methods and Materials: Patients treated for DCIS with lumpectomy and negative margins were eligible for 2 consecutive hypofractionated whole-breast RT clinical trials. The first trial (New York University [NYU] 01-51) prescribed to the whole breast 42 Gy (2.8 Gy in 15 fractions) and the second trial (NYU 05-181) 40.5 Gy (2.7 Gy in 15 fractions) with an additional daily boost of 0.5 Gy to the surgical cavity. Results: Between 2002 and 2009, 145 DCIS patients accrued, 59 to the first protocol and 86 to the second trial. Median age was 56 years and 65% were postmenopausal at the time of treatment. Based on optimal sparing of normal tissue, 79% of the patients were planned and treated prone and 21% supine. At 5 years' median follow-up (60 months; range 2.6-105.5 months), 6 patients (4.1%) experienced an ipsilateral breast recurrence in all cases of DCIS histology. In 3/6 patients, recurrence occurred at the original site of DCIS and in the remaining 3 cases outside the original tumor bed. New contralateral breast cancers arose in 3 cases (1 DCIS and 2 invasive carcinomas). Cosmetic self-assessment at least 2 years after treatment is available in 125 patients: 91% reported good-to-excellent and 9% reported fair-to-poor outcomes. Conclusions: With a median follow-up of 5 years, the ipsilateral local recurrence rate is 4.1%, comparable to that reported from the NSABP (National Surgical Adjuvant Breast and Bowel Project) trials that employed 50 Gy in 25 fractions of radiotherapy for DCIS. There were no invasive recurrences. These results provide preliminary evidence that accelerated hypofractionated external beam radiotherapy is a viable option for DCIS.

    Full Text Available Aim of the study : Due to the emergence of new therapeutic opportunities in the second-line treatment of metastatic renal cell carcinoma, the choice of the appropriate medication requires consideration. Making the selection one should take into account the likelihood of response, the probability of toxicity, properties of the drug and the clinical characteristics of the patient. Aim of the work was to confirm antitumor efficacy of axitinib in patients with metastatic clear-cell renal-cell carcinoma in the second line treatment remaining under the care of our institution. The primary objective was to determine antitumor activity, secondary – to evaluate progression free survival, safety of the treatment and to analyse clinical characteristics of treated population. Results: Treatment records of 27 patients (9 females, 18 males treated from October 2014 to the present (July 2016 were reviewed. The median duration of treatment which corresponds to the time to disease progression in observed population was 6 months (range: under 1 month – 16 months. 1 patient (3.7% had got objective response (PR, partial remission. Clinical benefit rate (PR + SD (stable disease was 66%. 9 patients (33.33% experienced treatment toxicity only in the first degree of CTCAE (common toxicity criteria for adverse events, 11 patients (40.74% presented the second degree toxicity and 5 patients (18.5% – third degree. The most commonly reported treatment related adverse events were diarrhea (47%, fatigue (26%, hand-foot syndrome (26%, deterioration of blood pressure control (22.2%, abnormal liver function tests (18.5%, mucositis (11.1%.We observed 3 cases of unacceptable toxicity. Conclusions : Axitinib confirms its effectiveness also in situ ation outside clinical trials, however, it is characterized by significant toxicity.

    Purpose: To evaluate the feasibility, safety, and clinical benefits of percutaneous laser ablation (PLA) in patients with unresectable primary and metastatic adrenocortical carcinoma (ACC). Patients and methods: Four patients with hepatic metastases from ACC and a Cushing's syndrome underwent ultrasound-guided PLA. In one case the procedure was performed also on the primary tumor. Results: After three sessions of PLA, the primary tumor of 15 cm was ablated by 75%. After 1-4 (median 1) sessions of PLA, five liver metastases ranging from 2 to 5 cm were completely ablated, while the sixth tumor of 12 cm was ablated by 75%. There were no major complications. Treatment resulted in an improvement of performance status and a reduction of the daily dosage of mitotane in all patients. The three patients with liver metastases presented a marked decrease of 24-h urine cortisol levels, an improved control of hypertension and a mean weight loss of 2.8 kg. After a median follow-up after PLA of 27.0 months (range, 9-48 months), two patients have died of tumor progression, while two other patients remain alive and free of disease. Conclusions: Percutaneous laser ablation is a feasible, safe and well tolerated procedure for the palliative treatment of unresectable primary and metastatic ACC. Further study is required to evaluate the impact of PLA on survival.

    Full Text Available Metastatic renal cell cancer (RCC is a malignant disease without curative treatment. These patients are usually symptomatic and desperate for effective palliative treatment. Radiotherapy, chemotherapy, and hormonal therapy are not effective in these patients. A multimodal approach consisting of cytoreductive nephrectomy, systemic therapy (which includes cytokines or targeted molecules, and metastasectomy have been shown to be useful in prolonging the survival and improving the quality of life in a select group of patients with metastatic renal cancer. Patients with oligometastatic disease, good performance status, and delayed presentation of the secondaries have better results following this integrated approach. Although there is some controversy regarding the order in which nephrectomy and systemic therapy are to be instituted, well-controlled studies like the South West Oncology Group and European organization research and treatment of cancer have shown that upfront nephrectomy gives better survival compared to neoadjuvant systemic therapy followed by nephrectomy. This order is the standard presently. Of late, with better understanding of the genetic basis and the biology of the various subtypes of renal cell carcinoma, targeted molecular therapies have emerged as an equally effective alternative therapy to cytokines. Recent reports have proven that targeted therapy is more effective with comparable side effects. Metastasectomy in a subgroup of patients improves survival and quality of life specifically in those with lung secondaries and painful bone metastases.

    Whole body counters are not only used in measuring radioactivity in the body for radiation protection purposes but also in the measurement of iron absorption, body potassium and cesium, chronic blood loss, and also in the determination of the effectiveness of surgery, thyroid hormone and radioactive iodine therapy in thyroid carcinoma. This report deals with our experience in the use of a shadow-shield whole body counter in the determination of I-131 uptake by metastatic lesions of cancer of thyroid after total thyroidectomy and ablation therapy with I-131. This study was undertaken jointly by the Department of Nuclear Medicine, Veterans Memorial Hospital and the Biomedical Research Division of the Philippine Atomic Energy Commission. Preliminary results indicate that the 22 patients who underwent whole body counting after total thyroidectomy I-131 ablation therapy, 9 patients had elevated percentage retention of I-131, 10 patients with normal values and 3 patients with rising values. Foci of I-131 concentration in those with elevated and rising percentage concentration values were seen in the thyroidal bed scintiscans, while the 10 patients with normal values had negative scintiscans. The results of our observations confirm the results obtained by other workers abroad. Our preliminary results indicate that with the use of whole body counters a sensitive method of assessing whether functioning metastatic lesion of cancer of the thyroid still exist after total thyroidectomy and I-131 ablation therapy can be provided.

    To explore the reliability and feasibility of blood oxygenation level-dependent-based functional magnetic resonance imaging (BOLD-fMRI) to depict hypoxia in breast invasive ductal carcinoma. A total of 103 women with 104 invasive ductal carcinomas (IDCs) underwent breast BOLD-fMRI at 3.0 T. Histological specimens were analysed for tumour size, grade, axillary lymph nodes and expression of oestrogen receptors, progesterone receptors, human epidermal growth factor receptor 2, p53, Ki-67 and hypoxia inducible factor 1{alpha} (HIF-1{alpha}). The distribution and reliability of R2* were analysed. Correlations of the R2* value with the prognostic factors and HIF-1{alpha} were respectively analysed. The R2* map of IDC demonstrated a relatively heterogeneous signal. The mean R2* value was (53.4 {+-} 18.2) Hz. The Shapiro-Wilk test (W = 0.971, P = 0.020) suggested that the sample did not follow a normal distribution. The inter-rater and intrarater correlation coefficient was 0.967 and 0.959, respectively. The R2* values of IDCs were significantly lower in patients without axillary lymph nodes metastasis. The R2* value had a weak correlation with Ki67 expression (r = 0.208, P = 0.038). The mean R2* value correlated moderately with the level of HIF-1{alpha} (r = 0.516, P = 0.000). BOLD-fMRI is a simple and non-invasive technique that yields hypoxia information on breast invasive ductal carcinomas. (orig.)

    Full Text Available Background. Renal cell carcinoma (RCC has unpredictable and diverse behavior. The classic triad of hematuria, loin pain, and abdominal mass is uncommon. At time of diagnosis, 25%–30% of patients are found to have metastases. Bones, lungs, liver, and brain are the frequent sites of metastases. RCC with metastasis to the head and neck region and thyroid gland is the rarest manifestation and anaplastic carcinoma behaving metastatic thyroid mass is an extremely rare presentation of RCC. Case Presentation. A 56-year-old Saudi man with past history of right radical nephrectomy 5 years back presented with 3 months history of rapid increasing neck mass with dysphagia, presenting like anaplastic thyroid carcinoma. Tru-cut biopsy turned out to be metastatic renal cell carcinoma. Patient was treated with radiation therapy 30 Gy in 10 fractions to mass. Patient died 4 months after the discovery of anaplastic thyroid looking metastasis. Conclusion. Rapidly progressing thyroid metastases secondary to RCC are rare and found often unresectable which are not amenable to surgery. Palliative radiotherapy can be considered for such patients.

    Invasive lobular carcinoma (ILC) is known to be the second most common histological type following invasive ductal carcinoma (IDC). Definitive clinical features of ILC are controversial. We retrospectively analyzed a cohort of 330 patients with metastatic breast cancer, 303 of IDC, 19 of ILC, and 8 of others. We compared the patient age and tumor-node-metastasis factors, disease-free survival (DFS), estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor 2 (HER2) expression at the primary site between ILC and IDC. We then selected the patients in the ER + or PR + /HER2 - subtype specifically and compared sites of recurrence, and the survival curve starting from the point of development of metastatic disease. The clinical stage was significantly higher in the ILC patients than in the IDC (p = 0.001). The mean (±SD) of DFS for the ILC and IDC patients was 2.6 ± 0.6 and 2.4 ± 0.3 years, respectively, with no significant difference (p = 0.18). However, the hormone receptor status was same between both groups; the rate of HER2 positivity was significantly lower in the ILC group (0%) than in the IDC group (16.2%) (p = 0.05). In ER + or PR + /HER2 - subtype, the mean DFS for the ILC and IDC was 2.9 ± 0.6 and 3.1 ± 0.3 years, and the median survival time after the recurrence for ILC and IDC patients was 4.2 ± 0.7 and 5.6 ± 0.7 years, respectively, with no significant difference (p = 0.77). The frequency of lung metastases was significantly lower in the ILC group (6.3%) than in the IDC group (53.7%) (p cancer patients with ILC. We need to reveal the definitive feature of ILC and develop new therapeutic strategies to prevent the dissemination of ILCs.

    The treatment of advanced renal cell carcinoma has evolved dramatically over recent years. In this review, we will summarize current and emerging therapies based on molecular targets and provide insight into treatment strategy for metastatic renal cell carcinoma. We have witnessed a paradigm shift in the therapeutic landscape as treatment was formerly reliant on cytokine-based agents which have now been replaced with therapies targeting angiogenesis, mammalian target of rapamycin pathways, and immune responses. These dramatic changes are primarily due to our improved understanding of the underlying mutations and molecular mechanisms leading to tumorigenesis and progression. We now have targeted agents in the form of small-molecule tyrosine kinase inhibitors, monoclonal antibodies, and mTOR inhibitors. Moreover, immunotherapy-targeting checkpoints of T-lymphocyte activity has provided increased overall survival and a new class of agents with potential to radically change the treatment options. With these agents and their combination, durable responses are increasingly seen even though treatment resistance remains a huge challenge. New treatment strategies are rapidly developing and the therapeutic landscape is expected for further evolution.

    Full Text Available Efficacy of new molecularly targeted drugs in the treatment of renal cell carcinoma (RCC, confirmed in clinical studies in relation to survival and prolongation of time to progression, has became a big chance for patients with metastatic renal cell cancer. Axitinib is a potent and selective receptor tyrosine kinase for vascular endothelial growth factor (VEGFR-1, -2, -3, platelet-derived growth factor  (PDGRF- and c-KIT. This is a case report of a 57-year old female patient with a history of left nephrectomy due to clear cell renal cell carcinoma. The patient had received three prior systemic treatments (interferon – sorafenib – everolimus. After consecutive progression the patient was qualified to 4th line therapy – axitinib at a dose of 5 mg twice daily. Partial response to treatment was achieved. After 6 months therapy was stopped due to the disease progression. The total time to progression was 37.5 months. The total survival time from the disease diagnosis was 45 months. Based on literature date and own experience we showed that sequential treatment RCC is associated with improved survival. In summary, axitinib may be an effective drug after failure of tyrosine-kinase inhibitor (TKI therapy in previous lines of therapy.

    Basal cell carcinoma (BCC) is the most common carcinoma in the community, but the incidence of metastatic events is exceedingly low. The few reported cases most often appear in regional nodes or the lungs, and patients usually exhibit multiple concurrent organs of spread at the time of diagnosis. We report a case of primary BCC located on the left forehead of a 48-year-old man, which metastasized exclusively to the bone and bone marrow, associated with hematologic disorders. A short review of the literature is included. Pathologic examination of the tumor located on the left forehead showed BCC. The patient underwent two surgical excisions because of local recurrence. Three years later, the patient developed a bicytopenia (anemia and thrombocytopenia). The bone marrow biopsy revealed metastasis of BCC. There were no abnormal findings in the other routine laboratory tests and radiologic investigations, except for the bone scan which showed multifocal skeletal metastases. The patient received two cycles of chemotherapy with cisplatin 75 mg/m(2) before he died as a result of hemorrhagic complications and progressive disease. Metastasis of BCC is a very rare condition that should not be overlooked. The prognosis remains very poor. We emphasize the importance of long-term follow-up of such patients.

    Merkel cell carcinoma is a rare neuroendocrine tumor of subspecialized dermal mechanoreceptors, associated with immunosuppression. The usual ophthalmic presentation is an eyelid lesion. The authors present a case of biopsy-proven orbital metastatic Merkel cell carcinoma in the absence of any eyelid lesion, in an immunosuppressed patient with a history of multiple cancers. There are to the authors' knowledge only 2 other case reports of presumed metastatic Merkel cell carcinoma to the orbit, though neither were biopsied. Despite its rarity, metastatic Merkel cell carcinoma should be included in the differential of a metastatic orbital lesion, in the patient with a known or suspected cutaneous primary. The patient has had an excellent response to combined radiotherapy and programmed death-1 inhibitor pembrolizumab, and this case highlights the potential benefit of an exciting new biologic therapy.

    2015-01-01

    Introduction: There are an estimated 60,000 new cases of ductal carcinoma in situ (DCIS) each year. A lack of understanding in DCIS pathobiology has led to overtreatment of more than half of patients. We profiled the temporal molecular changes during DCIS transition to invasive ductal carcinoma (IDC) using in vivo DCIS progression models. These studies identified B cell lymphoma-9 (BCL9) as a potential molecular driver of early invasion. BCL9 is a newly found co-activator of Wnt-stimulated β-...

    Full Text Available Abstract Background A major challenge in the interpretation of genomic profiling data generated from breast cancer samples is the identification of driver genes as distinct from bystander genes which do not impact tumorigenesis. One way to assess the relative importance of alterations in the transcriptome profile is to combine parallel analyses that assess changes in the copy number alterations (CNAs. This integrated analysis permits the identification of genes with altered expression that map within specific chromosomal regions which demonstrate copy number alterations, providing a mechanistic approach to identify the 'driver genes'. Methods We have performed whole genome analysis of CNAs using the Affymetrix 250K Mapping array on 22 infiltrating ductal carcinoma samples (IDCs. Analysis of transcript expression alterations was performed using the Affymetrix U133 Plus2.0 array on 16 IDC samples. Fourteen IDC samples were analyzed using both platforms and the data integrated. We also incorporated data from loss of heterozygosity (LOH analysis to identify genes showing altered expression in LOH regions. Results Common chromosome gains and amplifications were identified at 1q21.3, 6p21.3, 7p11.2-p12.1, 8q21.11 and 8q24.3. A novel amplicon was identified at 5p15.33. Frequent losses were found at 1p36.22, 8q23.3, 11p13, 11q23, and 22q13. Over 130 genes were identified with concurrent increases or decreases in expression that mapped to these regions of copy number alterations. LOH analysis revealed three tumors with whole chromosome or p arm allelic loss of chromosome 17. Genes were identified that mapped to copy neutral LOH regions. LOH with accompanying copy loss was detected on Xp24 and Xp25 and genes mapping to these regions with decreased expression were identified. Gene expression data highlighted the PPARα/RXRα Activation Pathway as down-regulated in the tumor samples. Conclusion We have demonstrated the utility of the application of

    Zinc is known to play an important role in many cellular processes, and the levels of zinc are controlled by specific transporters from the ZIP (SLC39A) influx transporter group and the ZnT (SLC30A) efflux transporter group. The distribution of zinc was measured in 59 samples of invasive ductal carcinoma of breast using synchrotron radiation micro probe x-ray fluorescence facilities. The samples were formalin fixed paraffin embedded tissue micro arrays (TMAs) enabling a high throughput of samples and allowing us to correlate the distribution of trace metals with tumour cell distribution and, for the first time, important biological variables. The samples were divided into two classes, 34 oestrogen receptor positive (ER+ve) and 25 oestrogen receptor negative (ER-ve) based on quantitative immunohistochemistry assessment. The overall levels of zinc (i.e. in tumour and surrounding tissue) in the ER+ve samples were on average 60% higher than those in the ER-ve samples. The zinc levels were higher in the ER+ve tumour areas compared to the ER-ve tumour areas with the mean levels in the ER+ve samples being approximately 80% higher than the mean ER-ve levels. However, the non-tumour tissue regions of the samples contained on average the same levels of zinc in both types of breast cancers. The relative levels of zinc in tumour areas of the tissue were compared with levels in areas of non-tumour surrounding tissue. There was a significant increase in zinc in the tumour regions of the ER+ve samples compared to the surrounding regions (P < 0.001) and a non-significant increase in the ER-ve samples. When comparing the increase in zinc in the tumour regions expressed as a percentage of the surrounding non-tumour tissue zinc level in the same sample, a significant difference between the ER+ve and ER-ve samples was found (P < 0.01).

    This paper presents a deep learning approach for automatic detection and visual analysis of invasive ductal carcinoma (IDC) tissue regions in whole slide images (WSI) of breast cancer (BCa). Deep learning approaches are learn-from-data methods involving computational modeling of the learning process. This approach is similar to how human brain works using different interpretation levels or layers of most representative and useful features resulting into a hierarchical learned representation. These methods have been shown to outpace traditional approaches of most challenging problems in several areas such as speech recognition and object detection. Invasive breast cancer detection is a time consuming and challenging task primarily because it involves a pathologist scanning large swathes of benign regions to ultimately identify the areas of malignancy. Precise delineation of IDC in WSI is crucial to the subsequent estimation of grading tumor aggressiveness and predicting patient outcome. DL approaches are particularly adept at handling these types of problems, especially if a large number of samples are available for training, which would also ensure the generalizability of the learned features and classifier. The DL framework in this paper extends a number of convolutional neural networks (CNN) for visual semantic analysis of tumor regions for diagnosis support. The CNN is trained over a large amount of image patches (tissue regions) from WSI to learn a hierarchical part-based representation. The method was evaluated over a WSI dataset from 162 patients diagnosed with IDC. 113 slides were selected for training and 49 slides were held out for independent testing. Ground truth for quantitative evaluation was provided via expert delineation of the region of cancer by an expert pathologist on the digitized slides. The experimental evaluation was designed to measure classifier accuracy in detecting IDC tissue regions in WSI. Our method yielded the best quantitative

    Purpose: Patients treated for ductal carcinoma in situ (DCIS) with breast-conserving surgery (BCS) and radiation therapy (RT) at our center from 1976 to 1990 had a 15% actuarial 10-year local recurrence (LR) rate. Since then, improved mammographic and pathologic evaluation and greater attention to achieving negative margins may have resulted in a lower risk of LR. In addition, clinical implications of hormone receptor and HER-2 status in DCIS remain unclear. We sought to determine the following: LR rates with this more modern approach; the relation between LR and HER-2 status; and clinical and pathologic factors associated with HER-2{sup +} DCIS. Methods and Materials: We studied 246 consecutive patients who underwent BCS and RT for DCIS from 2001 to 2007. Of the patients, 96 (39%) were Grade III and the median number of involved tissue blocks was 3. Half underwent re-excision and 222 (90%) had negative margins (>2 mm). All received whole-breast RT (40-52 Gy) and 99% (244) received a tumor bed boost (8-18 Gy). Routine estrogen receptor (ER), progesterone receptor (PR), and HER-2 immunohistochemistry was instituted in 2003. Results: With median follow-up of 58 months, there were no LRs. Seven patients (3%) developed contralateral breast cancer (4 invasive and 3 in situ). Among 163 patients with immunohistochemistry, 124 were ER/PR{sup +}HER-2{sup -}, 27 were ER/PR{sup +}HER-2{sup +}, 6 were ER{sup -}/PR{sup -}HER-2{sup +}, and 6 were ER{sup -}/PR{sup -}HER-2{sup -}. On univariable analysis, HER-2{sup +}was significantly associated with Grade III, ER{sup -}/PR{sup -}, central necrosis, comedo subtype, more extensive DCIS, and postmenopausal status. On multivariable analysis, Grade III and postmenopausal status remained significantly associated with HER-2{sup +}. Conclusions: In an era of mammographically identified DCIS, larger excisions, widely negative margins and the use of a tumor bed boost, we observed no LR regardless of ER/PR/HER-2 status.

    Phyllodes tumors are fibroepithelial lesions and malign forms are rare neoplasms with lower than 1% of all primary breast tumors. Malign forms are usually behaves like sarcomas because they occur in the stroma of the breast. Also proliferation of epithelium occurs and even it is less often, the epithelial component of phyllodes tumors can transform into malignancy too. This epithelial malignancies are usually in the form of infiltrative carcinomas and non-invasive tumors arising in benign phyllodes tumors are much rarer but can be seen. Literature include very few cases about this situation and cases are usually old woman. We report a 19-year old patient who was diagnosed with ductal carcinoma in situ arising in benign phyllodes tumor of the breast. PMID:28331678

    BACKGROUND: The incidence of ductal carcinoma in situ (DCIS) has increased markedly with the introduction of population-based mammographic screening. DCIS is usually diagnosed non-operatively. Although sentinel lymph node biopsy (SNB) has become the standard of care for patients with invasive breast carcinoma, its use in patients with DCIS is controversial. AIM: To examine the justification for offering SNB at the time of primary surgery to patients with a needle core biopsy (NCB) diagnosis of DCIS. METHODS: A retrospective analysis was performed of 145 patients with an NCB diagnosis of DCIS who had SNB performed at the time of primary surgery. The study focused on rates of SNB positivity and underestimation of invasive carcinoma by NCB, and sought to identify factors that might predict the presence of invasive carcinoma in the excision specimen. RESULTS: 7\\/145 patients (4.8%) had a positive sentinel lymph node, four macrometastases and three micrometastases. 6\\/7 patients had invasive carcinoma in the final excision specimen. 55\\/145 patients (37.9%) with an NCB diagnosis of DCIS had invasive carcinoma in the excision specimen. The median invasive tumour size was 6 mm. A radiological mass and areas of invasion <1 mm, amounting to "at least microinvasion" on NCB were predictive of invasive carcinoma in the excision specimen. CONCLUSIONS: SNB positivity in pure DCIS is rare. In view of the high rate of underestimation of invasive carcinoma in patients with an NCB diagnosis of DCIS in this study, SNB appears justified in this group of patients.

    Full Text Available OBJECTIVE: To evaluate the expression of the cell adhesion molecules E-cadherin and N-cadherin and the transcription factor Snail in invasive ductal breast carcinomas and to determine their relationships with clinicopathological features. METHODS: Immunohistochemistry was used to examine E-cadherin, N-cadherin, and Snail protein expression in 132 invasive breast carcinomas. RESULTS: The expression of E-cadherin was decreased (negative or weak in 37.1% of invasive carcinomas, while N-cadherin and Snail overexpression were detected in 51.9% and 40.9% of carcinomas, respectively. Low E-cadherin expression was significantly correlated with poorly differentiated carcinoma (53.1%, positive node status (80.9%, poor Nottingham Prognostic Index (64.7%, and the presence of estrogen and progesterone receptors. Overexpression of N-cadherin and Snail were also significantly correlated with poorly differentiated carcinoma, positive node status, and poor Nottingham Prognostic Index but were correlated with the absence of hormone receptors. Loss of E-cadherin immunoexpression was strongly associated with the presence of membranous N-cadherin (87.8% and nuclear Snail (69.4%. CONCLUSION: Loss of E-cadherin and overexpression of N-cadherin and Snail in breast carcinomas may play a central role in the development of invasive ductal breast carcinoma. These biomarkers may provide a valuable reference for the study of invasive ductal carcinoma progression and to characterize the biological behavior of the tumor. In the future, increased N-cadherin and decreased E-cadherin expression may be used as indicators of the progression and prognosis of invasive ductal carcinoma.

    Breast-conserving surgery has become an important way of surgical treatment for breast cancer worldwide nowadays. Multiphoton microscopy (MPM) has the ability to noninvasively visualize tissue architectures at the cellular level using intrinsic fluorescent molecules in biological tissues without the need for fluorescent dye. In this study, MPM is used to image the microstructures of terminal duct lobular unit (TDLU), invasive ductal carcinoma and the boundary region between normal and cancerous breast tissues. Our study demonstrates that MPM has the ability to not only reveal the morphological changes of the cuboidal epithelium, basement membrane and interlobular stroma but also identify the boundary between normal breast tissue and invasive ductal carcinoma, which correspond well to the Hematoxylin and Eosin (H and E) images. Predictably, MPM can monitor surgical margins in real time and provide considerable accuracy for resection of breast cancerous tissues intraoperatively. With the development of miniature, real-time MPM imaging technology, MPM should have great application prospects during breast-conserving surgery.

    Even with adequate history, the distinction of cutaneous metastatic breast carcinoma from primary sweat gland carcinoma can be difficult. Although previous studies have attempted to separate these tumors with various immunohistochemical panels, those series have been limited by small numbers of patients as well as the inclusion of benign sweat gland tumors. In this analysis, stains for p63, CK5/6, and D2-40 were included, as well as GATA3 and mammaglobin, in an evaluation of 21 primary sweat gland carcinomas and 33 examples of cutaneous metastatic breast carcinoma. Immunoreactivity for p63, CK5/6, D2-40, GATA3, and mammaglobin was respectively observed in 81%, 71%, 52%, 71%, and 5% of sweat gland carcinomas compared with 6%, 6%, 6%, 91%, and 45% of metastatic breast carcinomas. These differences were statistically significant for p63, CK5/6, and D2-40. For the diagnosis of metastatic breast carcinoma, GATA3 was the most sensitive marker (91%), but its sensitivity was substantially lower. Mammaglobin was 95% specific for breast carcinoma but again suffered from limited sensitivity (45%) in this context. These data suggest that p63 and CK5/6 are specific determinants for sweat gland carcinoma in the stated setting. In the absence of those analytes, metastatic breast carcinoma cannot always be identified to the exclusion of a primary tumor. This diagnostic scenario continues to require the procurement of a detailed clinical history regarding the number and duration of skin lesions in any given case.

    The HER2 oncogene shows expression or amplification, or both, in approximately 15% to 20% of breast cancers and has been associated with poor prognosis and a response to trastuzumab therapy. HER2 gene status determines the eligibility of breast cancer patients for trastuzumab therapy and a large fraction (41-56%) of these patients respond to targeted therapy. Several studies have related the increased expression of HER2 to an increased copy number of chromosome 17, rather than amplification of the HER2 gene. We compared the results of immunohistochemistry and fluorescence in situ hybridization in both invasive ductal and invasive lobular carcinomas, to determine the frequency of chromosome 17 aneuploidy associated with discordant results. In total, 390 invasive ductal carcinomas and 180 invasive lobular carcinomas diagnosed from January 2000 to December 2005 were included in the study only if results were available for immunohistochemistry (HercepTest; DAKO, Carpinteria, California) and fluorescence in situ hybridization (PathVysion HER2 DNA Probe Kit; Abbott Laboratories, Des Plaines, Illinois). Tumors classified as invasive ductal carcinomas were graded according to the Bloom-Richardson grading system. Correlation between the results of immunohistochemistry and fluorescence in situ hybridization was performed for all categories. Among invasive ductal carcinomas, 29% (115/390) showed chromosome 17 aneuploidy, mostly associated with grade 3/HER2 2+ (45%) or grade 2/HER2 3+ (55%) that were not amplified. Also, 34% (12/35) of invasive lobular carcinomas showed chromosome 17 aneuploidy; approximately one-third of these cases were HER2 2+ (33%) and HER2 3+ (37%) that were not amplified. Discordance between the results of immunohistochemistry and fluorescence in situ hybridization in both ductal and lobular carcinomas is largely associated with chromosome 17 aneuploidy.

  15. Eliminating "ductal carcinoma in situ" and "lobular carcinoma in situ" (DCIS and LCIS) terminology in clinical breast practice: The cognitive psychology point of view.

    There is evidence from the literature that the terms "ductal carcinoma in situ" and "lobular carcinoma in situ" (DCIS and LCIS) should be eliminated in clinical breast cancer practice and replaced with the new "ductal intraepithelial neoplasia" (DIN) and "lobular intraepithelial neoplasia" (LIN) terminology. The main purpose of the present article is to expand on this argument from a cognitive psychology perspective and offer suggestions for further research, emphasizing how the elimination of the term "carcinoma" in "in situ" breast cancer diagnoses has the potential to reduce both patient and health care professional confusion and misperceptions that are often associated with the DCIS and LCIS diagnoses, as well as limit the adverse psychological effects of women receiving a DCIS or LCIS diagnosis. We comment on the recent peer-reviewed literature on the clinical implications and psychological consequences for breast cancer patients receiving a DCIS or LCIS diagnosis and we use a cognitive perspective to offer new insight into the benefits of embracing the new DIN and LIN terminology. Using cognitive psychology and cognitive science in general, as a foundation, further research is advocated in order to yield data in support of changing the terminology and therefore, offer a chance to significantly improve the lives and psychological sequelae of women facing such a diagnosis.

    Full Text Available Background: Basal cell carcinoma (BCC is relatively uncommon in Malaysia with non-melanomatous skin cancer being the 12th most common malignancy in Malaysia.Metastatic basal cell carcinoma (MBCC is extremely rare and the incidence is estimated to be 0.0028% to 0.55% among all BCC. We report a case of MBCC with a summary of clinical and histopathology findings; and the management. Case presentation: A 69-year-old Chinese man, presented with a left wrist mass for 4 years. The mass was on the dorsal surface of the wrist, ulcerated, and measured 15 x 10cm. The tumour size was 2.5 × 8.6 × 10cm on MRI, extending into the extensor digitorum tendons and possible invasion into the lumbricals. He underwent wide excision of the mass, decorticotomy of left 3rd to 5th metacarpal bones and amputation of 2nd metacarpal bone. Histopathological examination showed BCC involving whole skin thickness invading the subcutaneous fat but sparing the underlying tissues, resections margins were clear, maximal diameter was 11.5 cm. The tumour was staged as pT2N0M0. After 18 months, he developed an 8 × 10cm left axillary mass which was fungating and bleeding. CT scan also showed multiple lung metastases. Repeat biopsy of the left axillary mass showed BCC with similar appearance as the previous histopathology examination. Radiotherapy to the left axilla was given (65 Gray in 30 fractions for local control as the tumour was bleeding profusely. Discussion: A review by Wysong et al. for 194 cases of MBCC suggests that its prognosis remains poor over the past 30 years, with the median overall survival of 10 months from diagnosis despite the introduction of systemic chemotherapy and radiotherapy. Most common metastatic sites are the regional lymph nodes, lungs and bone. Large lesions (particularly those over 10 cm2 and tumours that invade deep structures, such as cartilage, skeletal muscle, or bone, are most likely to metastasize.

    Approximately 1 in 5 women diagnosed with breast cancer are considered to have in situ disease, most often termed ductal carcinoma in situ (DCIS). Though recognized as a risk factor for the development of more invasive cancer, it remains unclear what factors contribute to DCIS development. It has been shown that inflammation contributes to the progression of a variety of tumor types, and nuclear factor kappa B (NF-κB) is recognized as a master-regulator of inflammatory signaling. However, the contributions of NF-κB signaling to tumor initiation are less well understood. Aberrant up-regulation of NF-κB activity, either systemically or locally within the breast, could occur due to a variety of commonly experienced stimuli such as acute infection, obesity, or psychological stress. In this study, we seek to determine if activation of NF-κB in mammary epithelium could play a role in the formation of hyperplastic ductal lesions. Our studies utilize a doxycycline-inducible transgenic mouse model in which constitutively active IKKβ is expressed specifically in mammary epithelium. All previously published models of NF-κB modulation in the virgin mammary gland have been constitutive models, with transgene or knock-out present throughout the life and development of the animal. For the first time, we will induce activation at later time points after normal ducts have formed, thus being able to determine if NF-κB activation can promote pre-malignant changes in previously normal mammary epithelium. We found that even a short pulse of NF-κB activation could induce profound remodeling of mammary ductal structures. Short-term activation created hyperproliferative, enlarged ducts with filled lumens. Increased expression of inflammatory markers was concurrent with the down-regulation of hormone receptors and markers of epithelial differentiation. Furthermore, the oncoprotein mucin 1, known to be up-regulated in human and mouse DCIS, was over-expressed and mislocalized in the

    Atezolizumab, a humanized immunoglobulin G1 (IgG1) monoclonal antibody targeting human programmed death-ligand 1 (PD-L1), is US Food and Drug Administration (FDA) approved in metastatic urothelial carcinoma (MUC) and is being investigated in various malignancies. This analysis based upon 906 patients from two phase I and one phase II MUC studies, is the first report of the clinical pharmacokinetics (PK) and pharmacodynamics (PD) of atezolizumab. Atezolizumab exhibited linear PK over a dose range of 1-20 mg/kg, including the labeled 1,200 mg dose. The clearance, volume of distribution, and terminal half-life estimates from population pharmacokinetic (PopPK) analysis of 0.200 L/day, 6.91 L, and 27 days, respectively, were as expected for an IgG1. Exposure-response analyses did not identify statistically significant relationships with either objective response rate or adverse events of grades 3-5 or of special interest. None of the statistically significant covariates from PopPK (body weight, gender, antitherapeutic antibody, albumin, and tumor burden) would require dose adjustment. © 2016 American Society for Clinical Pharmacology and Therapeutics.

    The introduction of targeted therapies has led to a novel situation regarding monitoring of metastatic renal cell carcinoma (mRCC): patients treated with these new drugs have a significantly longer life expectancy than just a few years ago. In order to maximize the treatment benefit, new demands have come up on the assessment of tumor progression: timing and interpretation of imaging studies are crucial for optimal therapeutic management. Detailed knowledge of the new compounds' mode of action is important as it is different from that of classic cytotoxic drugs. The RECIST criteria constitute the standard for evaluation. Following recommendations made by the German Cancer Society's (DKG) interdisciplinary task force, targeted therapies should strive for a sufficient treatment duration in each line of therapy in order to achieve the best therapeutic outcome. Treatment is continued until clinical progression occurs. Assessing therapeutic efficacy with adequate imaging techniques 6-9 weeks after the beginning of therapy is recommended. Subsequent follow-up examinations should be repeated using identical imaging modalities every 2-3 months. For cyclically applied drugs such as Sunitinib, examinations should be carried out at identical time points within the treatment cycle. Copyright 2010 S. Karger AG, Basel.

    Juvenile fibroadenoma is an uncommon histologic variant of fibroadenoma that frequently shows a remarkable and rapid growth. The development of a carcinoma within a fibroadenoma, either in situ or invasive, is a rare condition. We encountered a 36-year-old woman with a palpable mass in the right breast. The radiologic findings were indicative of a fibroadenoma in the breast. Sonographic guided biopsy using a 14G core needle revealed the presence of ductal carcinoma in situ (DCIS) within the j...

    2003-01-01

    Our previous characterization of a human breast tumor metastasis model identified several candidate metastasis genes. The expression of osteopontin (OPN) correlated with the metastatic phenotype, whereas thrombospondin-1 (TSP-1) and tyrosinase-related protein-1 (TYRP-1) correlated with the nonmetastatic phenotype of independent MDA-MB-435 cell lines implanted orthotopically into athymic mice. The aim of the present study was to examine the cellular distribution of these molecules in human breast tissue and to determine whether the relative expression level of these three genes is associated with human breast tumor metastasis. Sixty-eight fresh, frozen specimens including 31 primary infiltrating ductal carcinomas, 22 nodal metastases, 10 fibroadenomas, and five normal breast tissues were evaluated for OPN expression, TSP-1 expression and TYRP-1 expression. Immunohistochemistry was performed to monitor the cellular distribution and to qualitatively assess expression. Quantitative analysis was achieved by enrichment of breast epithelial cells using laser-capture microdissection and subsequent real-time, quantitative PCR. The epithelial components of the breast tissue were the source of OPN and TSP-1 expression, whereas TYRP-1 was present in both the epithelial and stromal components. Both OPN and TSP-1 expression were significantly higher in malignant epithelial sources over normal and benign epithelial sources, but no difference in expression levels was evident between primary tumors with or without metastases, nor between primary and metastatic carcinomas. Elevated expression of OPN and TSP-1 may play a role in the pathogenesis of breast cancer. The multiplex analysis of these molecules may enhance our ability to diagnose and/or prognosticate human breast malignancy

    IQ-domain GTPase-activating protein 1 is a scaffolding protein with multidomain which plays a role in modulating dishevelled (Dvl) nuclear translocation in canonical Wnt pathway. However, the biological function and mechanism of IQ-domain GTPase-activating protein 1 in invasive ductal carcinoma (IDC) remain unknown. In this study, we found that IQ-domain GTPase-activating protein 1 expression was elevated in invasive ductal carcinoma, which was positively correlated with tumor grade, lymphatic metastasis, and poor prognosis. Coexpression of IQ-domain GTPase-activating protein 1 and Dvl in the nucleus and cytoplasm of invasive ductal carcinoma was significantly correlated but not in the membrane. Postoperative survival in the patients with their coexpression in the nucleus and cytoplasm was obviously lower than that without coexpression. The positive expression rates of c-myc and cyclin D1 were significantly higher in the patients with nuclear coexpression of Dvl and IQ-domain GTPase-activating protein 1 than that with cytoplasmic coexpression, correlating with poor prognosis. IQ-domain GTPase-activating protein 1 significantly enhanced cell proliferation and invasion in invasive ductal carcinoma cell lines by interacting with Dvl in cytoplasm to promote Dvl nuclear translocation so as to upregulate the expression of c-myc and cyclin D1. Collectively, our data suggest that IQ-domain GTPase-activating protein 1 may promote the malignant phenotype of invasive ductal carcinoma via canonical Wnt signaling, and it could be used as a potential prognostic biomarker for breast cancer patients.

    Full Text Available Introduction: Carcinoma ex pleomorphic adenoma (CXPA of the salivary glands has often a salivary duct carcinoma (SDC component, which resembles ductal carcinoma of the breast and frequently overexpresses human epidermal growth factor receptor-2 (HER2. We report a case of metastatic CXPA with SDC component who was treated with trastuzumab-based chemotherapy and has had a durable complete response. Case Report: A 74-year-old man was diagnosed with CXPA of the right parotid gland. The resected tumor was histologically diagnosed as CXPA with a predominant SDC component that showed strong positivity for HER2 protein and HER2 gene amplification. Multiple pulmonary metastatic lesions were detected after surgery, and combination chemotherapy with paclitaxel and trastuzumab was initiated. A complete response was confirmed after 7 treatment cycles, and no evidence of disease progression has been observed after 13 months of initiation of therapy. Conclusions: This report suggests a potential utility of trastuzumab-based chemotherapy for HER2-positive CXPA.

    Basal cell carcinoma (BCC) accounts for 80% of all nonmelanoma skin cancers. Its metastasis is extremely rare, ranging between 0.0028 and 0.55 of all BCC cases. The usual metastasis to lymph nodes, lungs, bones, or skin is from the primary tumor situated in the head and neck region in nearly 85% cases. A 69-year-old male developed progressively increasing multiple, fleshy, indurated, and at places pigmented noduloulcerative plaques over back, chest, and left axillary area 4 years after wide surgical excision of a pathologically diagnosed basal cell carcinoma. The recurrence was diagnosed as infiltrative BCC and found metastasizing to skin, soft tissue and muscles, and pretracheal and axillary lymph nodes. Three cycles of chemotherapy comprising intravenous cisplatin (50 mg) and 5-florouracil (5-FU, 750 mg) on 2 consecutive days and repeated at every 21 days were effective. As it remains unclear whether metastatic BCC is itself a separate subset of basal cell carcinoma, we feel that early BCC localized at any site perhaps constitutes a biological continuum that may ultimately manifest with metastasis in some individuals and should be evaluated as such. Long-standing BCC is itself potentially at risk of recurrence/dissemination; it is imperative to diagnose and appropriately treat all BCC lesions at the earliest.

Synchronous bilateral breast cancer in association with gynecomastia is exceptionally rare. We aim to report and evaluate the management outcome of 5 cases of gynecomastia associated with DCIS (1 bilateral and 4 unilateral). A retrospective database analysis of the surgical treatment outcome of 74 male patients who had gynecomastia was done. A bilateral subcutaneous nipple-preserving mastectomy approach was done to all. Histopathology reports were reviewed. 74 patients diagnosed and treated for gynecomastia were included. The incidence rate of gynecomastia in our hospital male patients was 0.17%. The mean age was 22 years, range 17-29 years. Five (6.76%) patients were found in histopathology specimens to have DCIS, 1 patient (23 years old) had bilateral DCIS of low grade, 4 patients had unilateral positive involvement, 3 had right breast DCIS, and 1 had left breast DCIS, and all were of low-grade papillary subtype. The incidence of ductal carcinoma in situ among our series gynecomastia patients was 6.76%. We conclude that gynecomastia is a benign breast disease but recent reports had described malignant variants, mostly DCIS, including 5 young males in our series. Therefore, regardless of the age group, histopathological examination of the resected gynecomastia tissue should be carefully done in all patients. Further evidence-based studies are needed to investigate the optimum management of incidental DCIS in gynecomastia specimens.

    To examine the patterns of care and outcomes for metastatic renal cell carcinoma (mRCC) in Australia, where there are limited reimbursed treatment options. In particular, we aim to explore prescribing patterns for first-line systemic treatment, the practice of an initial watchful-waiting approach, and the use of systemic treatments in elderly patients. Patients with mRCC undergoing treatment between 2006 and 2012 were identified from four academic hospitals in Victoria and Australian Capital Territory. Demographic, clinicopathological, treatment, and survival data were recorded by chart review. Descriptive statistics were used to report findings. Survival was estimated by the Kaplan-Meier method and compared using the log-rank test. The study was supported by a grant from Pfizer Australia. Our study identified 212 patients with mRCC for analysis. Patients were predominantly of clear cell histology (75%), Eastern Cooperative Oncology Group performance status 90 days before initiating treatment; these patients had a median OS of 56.3 months. Elderly patients (50 patients aged ≥70 years) were more likely to receive BSC alone than younger patients (46% vs 16%, P < 0.001). Of those who received systemic therapy, elderly patients were also more likely to have upfront dose reductions (30% vs 8%, P = 0.03). Our study of patients with mRCC treated in Australian centres showed that sunitinib was the most commonly prescribed systemic treatment between 2006 and 2012, associated with survival outcomes similar to pivotal studies. We also found that an initial watchful-waiting approach is commonly adopted without apparent detriment to survival. And finally, we found that age has an impact on the prescribing of systemic therapy. © 2015 The Authors BJU International © 2015 BJU International Published by John Wiley & Sons Ltd.

    Full Text Available Introduction. Patients with urothelial carcinoma of the bladder often present with metastases to regional lymph nodes, with lymphadenopathy on physical examination or radiographic imaging. Case Presentation. We present the case of a 73-year-old Caucasian man with presumed metastatic urothelial carcinoma of the bladder to regional pelvic and retroperitoneal lymph nodes. He underwent systemic chemotherapy for treatment of urothelial carcinoma and was discovered on restaging to have findings suggestive of disease progression but ultimately was found to have a concurrent secondary malignancy. Conclusion. Our case suggests that in patients with urothelial carcinoma, the concurrent presentation of regional lymphadenopathy may not be metastatic urothelial carcinoma and may warrant further investigation.

    The most common malignancy to cause gastric outlet obstruction is primary gastric adenocarcinoma and it is followed by carcinoma of the pancreas and gallbladder. Herein, we report a case of gastric outlet obstruction secondary to metastatic lobular breast carcinoma. Fifty-seven year old Caucasian female with recently diagnosed metastatic lobular breast carcinoma to skin was referred to gastroenterology for evaluation of dyspepsia and dysphagia. She has past medical history significant for acid reflux and Clostridium difficile colitis. Computed tomography of her abdomen showed diffused bowel wall thickening without evidence of bowel obstruction. Due to persistent abdominal pain, an upper endoscopy was performed. The upper endoscopy showed gastritis and gastric stenosis in the gastric antrum. These lesions were biopsied and dilated with a balloon dilator. The biopsy of the gastric antrum later showed a metastatic carcinoma of breast origin with typical tumor morphology and immune-phenotype. Differentiating metastatic breast carcinoma from primary gastric adenocarcinoma cannot be done using histological examination alone. Immunohistochemistry is needed to differentiate the two based on staining for estrogen and progesterone receptors. The presence of gross cystic disease fluid protein 15 is also suggestive of metastatic breast carcinoma. The stomach has a significant capacity to distend (up to 2-4 L of food) and malignant gastric outlet obstruction is often undetected clinically until a high-grade obstruction develops. Our case demonstrates valuable teaching point in terms of broadening our differentials for gastric outlet obstruction. When patients present with gastric outlet obstruction, both non-malignant and malignant causes of gastric outlet obstruction should be considered. Once adenocarcinoma has been determined to be the cause of gastric outlet obstruction, further immunohistochemistry is needed to differentiate breast carcinoma from other carcinomas.

    Basal cell carcinoma is the most common skin cancer, characterised by a slow growing behavior, metastasis are extremely rare, and it occurs in less than 0, 1% of all cases. Giant basal cell carcinoma is a rare form of basal cell carcinoma, more aggressive and defined as a tumor measuring more than 5 cm at its largest diameter. Only 1% of all basal cell carcinoma develops to a giant basal cell carcinoma, resulting of patient's negligence. Giant basal cell carcinoma is associated with higher potential of metastasis and even death, compared to ordinary basal cell carcinoma. We report a case of giant basal cell carcinoma metastaticin lung occurring in a 79 years old male patient, with a fatal evolution after one course of systemic chemotherapy. Giant basal cell carcinoma is a very rare entity, early detection of these tumors could prevent metastasis occurrence and improve the prognosis of this malignancy.

Little is described in the literature regarding this topic.Materials and methods: We reviewed our experiences from 2010 to 2015 and compared 40 patients with P-ILC, 126 patients with classic-ILC (C-ILC and 574 cases of high-grade invasive ductal carcinoma (HG-IDC. We studied the histologic and immunohistochemical features, clinical presentation and surgical treatment.Results: P-ILC is diagnosed at the same age and tumor diameter as those of the other two histologic types. It is associated more frequently with multiple lymph node metastases and high proliferative index, and HER2/neu is amplified in 10% of cases. In spite of sharing some histologic characteristics with C-ILC (same growth pattern, loss of E-cadherin expression, same genetic pathway, its clinical and pathologic features define an autonomous entity. Its surgical treatment is similar to those of C-ILC and HG-IDC.Conclusion: This is the first review comparing these three pathologic entities. Our findings may be useful in understanding this variety of invasive lobular carcinoma, and further studies are certainly needed in this field.

    Although primary basal cell carcinoma (BCC) represents an extremely common malignancy, metastases derived from BCC are exceedingly rare. The prognosis for metastatic BCC is poor, and little consensus exists regarding predictive factors or optimal treatment strategies. Here, we present the case of a 63-year-old man with BCC of the neck who subsequently developed multiple metastases to subcutaneous tissue, lymph nodes, and the parotid gland. Risk factors and clinical features of metastatic BCC are reviewed, as is the relationship of histopathologic subtype to metastatic behavior. Current chemotherapeutic and targeted therapies also are discussed in the context of recent advances in molecular biology. Copyright © 2012 John Wiley & Sons A/S.

    Breast carcinoma exceptionally leads to metastatic linitis plastica. Distinguishing a breast cancer metastasis to the stomach from a primary gastric cancer on the basis of clinical and radiological signs is very challenging. Thanks to being cognizant of the previous history of invasive lobular carcinoma and the gastric biopsy followed by immunohistochemical analysis, gastric metastasis can be diagnosed. Despite the use of chemotherapy and hormonal therapy, gastric metastasis remains often associated with poor prognosis. We present a case where gastric biopsy allowed a metastatic breast cancer to the stomach to be diagnosed and we discuss its clinical, diagnostic, pathological and therapeutic particularities.

  20. Development and evaluation of a prediction model for underestimated invasive breast cancer in women with ductal carcinoma in situ at stereotactic large core needle biopsy.

    Directory of Open Access Journals (Sweden)

    Suzanne C E Diepstraten

    Full Text Available BACKGROUND: We aimed to develop a multivariable model for prediction of underestimated invasiveness in women with ductal carcinoma in situ at stereotactic large core needle biopsy, that can be used to select patients for sentinel node biopsy at primary surgery. METHODS: From the literature, we selected potential preoperative predictors of underestimated invasive breast cancer. Data of patients with nonpalpable breast lesions who were diagnosed with ductal carcinoma in situ at stereotactic large core needle biopsy, drawn from the prospective COBRA (Core Biopsy after RAdiological localization and COBRA2000 cohort studies, were used to fit the multivariable model and assess its overall performance, discrimination, and calibration. RESULTS: 348 women with large core needle biopsy-proven ductal carcinoma in situ were available for analysis. In 100 (28.7% patients invasive carcinoma was found at subsequent surgery. Nine predictors were included in the model. In the multivariable analysis, the predictors with the strongest association were lesion size (OR 1.12 per cm, 95% CI 0.98-1.28, number of cores retrieved at biopsy (OR per core 0.87, 95% CI 0.75-1.01, presence of lobular cancerization (OR 5.29, 95% CI 1.25-26.77, and microinvasion (OR 3.75, 95% CI 1.42-9.87. The overall performance of the multivariable model was poor with an explained variation of 9% (Nagelkerke's R(2, mediocre discrimination with area under the receiver operating characteristic curve of 0.66 (95% confidence interval 0.58-0.73, and fairly good calibration. CONCLUSION: The evaluation of our multivariable prediction model in a large, clinically representative study population proves that routine clinical and pathological variables are not suitable to select patients with large core needle biopsy-proven ductal carcinoma in situ for sentinel node biopsy during primary surgery.

    A controversy of the role of Epstein-Barr virus (EBV) infection in breast carcinomas has been reported in the literature. We carried on this research to explore possible association between EBV infection and breast invasive ductal carcinoma (IDC) in Egyptian women attending our center. This study carried out at Sohag university hospital on 84 paraffin embedded samples of breast tissue, of them 42 breast IDC as the case group and 42 breast fibroadenomas as the control group. Nested PCRand immunohistochemistry (IHC) done separately for all samples to identify the Epstein-Barr nuclear antigen-1 (EBNA-1) gene and EBV latent membrane protein-1 (LMP-1) respectively, in breast cancer cells and controls. Specimen considered positive when both (EBNA-1) gene and LMP-1 were detected using PCR and IHC separately for the same sample, this was achieved by 10/42 (23.81%) of breast IDC (case group) and 6/42 (14.29%) of breast fibro-adenomas (control group) (P-value=0.4). Nodal involvement was the only parameter that demonstrated a significant statistical relationship with EBV presence in cancerous tissue with p-value=0.003. Our research could not find a significant statistical association between EBV infection and breast IDC in Egyptian women attending our center, but, there might be an association between the existence of EBV and tumor aggressiveness.

    Full Text Available Invasive lobular carcinoma is the second most common type of invasive breast cancer accounting for approximately 5-10% of all invasive breast carcinomas. The metastatic patterns of lobular and ductal carcinomas are significantly different. Most series report a greater propensity for lobular carcinoma to metastasize to the gastrointestinal tract, gynecological organs and the peritoneum, while ductal carcinoma most frequently relapses in the liver, lungs and the brain. Gastrointestinal system metastases were observed in 6-18%, the most commonly affected organ is the stomach. We aimed to present a female patient who had been diagnosed with invasive lobular carcinoma of the breast ten years ago and had invasive ductal carcinoma of the other breast three years ago, investigated for excessive ascites and found to have invasive lobular breast carcinoma metastasis to the stomach.

    The purpose of this study was to investigate the correlation of primary tumor FDG uptake to clinicopathological prognostic factors in invasive ductal carcinoma of the breast. We retrospectively reviewed 136 of 215 female patients with pathologically proven invasive ductal breast cancer from January 2008 to December 2011 who underwent F-18 FDG PET/CT for initial staging and follow-up after curative treatment with analysis of estrogen receptor (ER), progesterone receptor (PR) and human epithelial growth factor receptor 2 (HER2). The maximum standardized uptake value (SUV{sub max}) of the primary breast tumor was measured and compared with hormonal receptor and HER2 overexpression status. The high SUV{sub max} of primary breast tumors is significantly correlated with the clinicopathological factors: tumor size, histologic grade, TNM stage, negativity of ER, negativity of PR, HER2 overexpression and triple negativity. The recurrent group with non-triple negative cancer had a higher SUV{sub max} compared with the non-recurrent group, though no significant difference in FDG uptake was noted between the recurrence and non-recurrent groups in subjects with triple-negative cancer. Lymph node involvement was the independent risk factor for cancer recurrence in the multivariate analysis. In conclusion, high FDG uptake in primary breast tumors is significantly correlated with clinicopathological factors, such as tumor size, histologic grade, TNM stage, negativity of the hormonal receptor, HER2 overexpression and triple negativity. Therefore, FDG PET/CT is a helpful prognostic tool to direct the further management of patients with breast cancer.

    The introduction of molecular-targeted therapy has made dramatical changes to treatment for metastatic renal cell carcinoma. Currently, there are four vascular endothelial growth factor receptor-tyrosine kinase inhibitors and two mammalian target of rapamycin inhibitors in Japan. For the appropriate clinical use of these molecular-targeted drugs, the identification of prognostic and/or predictive factors in patients who received these drugs is required. Although molecular biological and genetic factors that determine the prognosis of patients with metastatic renal cell carcinoma have been reported, most of these factors are problematic in that the number of patients analyzed was small. In contrast, clinicopathological prognostic factors, including the practice of cytoreductive nephrectomy, pathological findings, metastatic sites and metastasectomy, and abnormal inflammatory response, have been identified by analyzing a relatively large number of patients. Several prognostic classification models that were developed by combining these clinicopathological factors are widely used in not only clinical trials, but also routine clinical practice. However, the quality of these prognostic models is considered to be insufficient regarding prognostic prediction of metastatic renal cell carcinoma patients and, thus, requires further improvements. Recently, basic and clinical studies have been extensively carried out for the identification of promising informative markers and for understanding molecular mechanisms of resistance to molecular-targeted drugs in metastatic renal cell carcinoma patients. The present review considers ongoing translational research efforts on clinicopathological, molecular biological, and genetic prognostic and/or predictive factors for metastatic renal cell carcinoma patients in the era of molecular-targeted therapy, and discusses the clinical implications of these findings. © 2015 The Japanese Urological Association.

    Our aim was to compare histologic and immunohistochemical features, surgical treatment and clinical course, including disease recurrence, distant metastases, and mortality between patients with invasive ductal carcinoma (IDC) or invasive lobular carcinoma (ILC). We included 1,745 patients operated for 1,789 breast tumors, with 1,639 IDC (1,600 patients) and 145 patients with ILC and 150 breast tumors. The median follow-up was 76 months. ILC was significantly more likely to be associated with a favorable phenotype. Prevalence of contralateral breast cancer was slightly higher for ILC patients than for IDC patients (4.0% versus 3.2%; p = n.s). ILC was more likely multifocal, estrogen receptor positive, Human Epidermal Growth Factor Receptor-2 (HER2) negative, and with lower proliferative index compared to IDC. Considering conservative surgery, ILC patients required more frequently re-excision and/or mastectomy. Prevalence of stage IIB and III stages were significantly more frequent in ILC patients than in IDC patients (37.4% versus 25.3%, p = 0.006). Positive nodes were significantly more frequent in the ILC patients (44.6% versus 37.0%, p = 0.04). After adjustment for tumor size and nodal status, frequencies of recurrence/metastasis, disease-free and specific survival were similar among patients with IDC and patients with ILC. In conclusion, women with ILC do not have worse clinical outcomes than their counterparts with IDC. Management decisions should be based on individual patient and tumor biologic characteristics rather than on lobular versus ductal histology. © 2015 Wiley Periodicals, Inc.

    Objective As breast cancer growth rate is associated with menopause, most screening programmes target mainly women aged 50-74. We studied the association between age at diagnosis and growth rate in this screening-specific age range. Methods We used data from breast cancer patients diagnosed in the screening programme in Nijmegen, the Netherlands. The data were restricted to the screening rounds when analogue mammography was used in both the screening and clinical setting. Growth rate expressed as tumour volume doubling time was based on increasing tumour size in longitudinal series of mammograms. Estimates were based on (a) tumours showing at least two measurable shadows, (b) tumours showing a shadow at detection only (left censored), and (c) tumours showing no growth (right-censored observation). All 293 tumours were consecutively diagnosed invasive ductal breast cancers in participants of the Nijmegen screening programme in the period 2000-2007. Results Depending on the assumptions made on tumour margins and mammographic density, the relation of volume doubling time with age non-significantly varies from a decrease of 3.3% to an increase of 1.4% for each year increase in age at diagnosis (all P-values ≥ 0.18). Applying left censoring on indistinct tumours, the geometric mean volume doubling time was 191 days (95% confidence interval 158-230). Conclusion We found no significant change in growth rate with age in women diagnosed with invasive ductal breast cancer in the screening age range 50-74. This outcome does not support differential screening intervals by age based solely on breast cancer growth rate for this particular group.

    Invasive lobular carcinomas have an increased propensity for distant metastases, particularly to the peritoneum, ovaries, and uterus. In contrast, distant metastases of nonpalpable lobular carcinomas are extremely rare, and the causes of underlying symptoms of primary carcinomas remain unclear. We report a case of an asymptomatic invasive lobular carcinoma with a primary mammary lesion in a patient with rectal stenosis. A 69-year-old Japanese woman presented to our hospital for treatment of constipation. Although rectal stenosis was confirmed, thorough testing of her lower digestive tract did not identify its cause. Thus, an exploratory laparotomy and tissue biopsy was performed, and the presence of an invasive lobular carcinoma was confirmed. Subsequent breast examinations showed that the invasive lobular carcinoma that led to the rectal stenosis was a metastatic lesion from a primary lesion of the breast duct. As the present breast lobular carcinoma was asymptomatic and nonpalpable, we did not initially consider metastatic breast cancer as a cause of her symptoms, and the final diagnosis was delayed. Peritoneal metastasis from nonpalpable invasive lobular carcinomas is very rare. However, breast cancer metastasis should be considered when carcinomatous peritonitis is present in a patient with an unknown primary cancer.

    Purpose: The purpose of this study was to evaluate the relationship between a family history of breast or ovarian cancer and outcome after breast-conserving surgery and radiation in women presenting with an initial diagnosis of ductal carcinoma in situ (DCIS) of the breast. Methods and Materials: A total of 146 consecutive women with a pathologic diagnosis of ductal carcinoma in situ as their first diagnosis of any breast cancer were identified; 28 (19%) had a positive family history of breast or ovarian cancer in a first-degree relative, 27 (19%) had a positive family history in a second-degree relative, and 91 (62%) had no family history. Pathologic, clinical, and treatment factors, and clinical outcomes for each family history group were compared. Cosmesis and complications were recorded at each follow-up. Patients were treated between 1978 and 1995, and the median follow-up was 7.1 years. Results: Patients with a positive family history in a first- or second-degree relative each had an 8% incidence of local failure at 10 years, while the negative family history group demonstrated a 16% local failure rate (p = 0.33). Overall survival at 10 years for patients with a positive family history in a first- or second-degree relative was 100% and for those with a negative family history was 91% (p = 0.08). The negative family history group had a higher median age that may account for the difference in overall survival. Cause-specific survival (CSS) was 97%, 100%, and 99%, respectively, at 10 years (p = 0.25). There were no differences in the cosmetic results or complication rates between women with a positive or negative family history. Conclusion: We have shown that a family history of breast and/or ovarian cancer is not associated with an adverse outcome for women treated with breast conservation therapy for DCIS. Local recurrence, cause-specific survival, overall survival, cosmesis, and complication rates were comparable to that of similarly treated women with

    Metastatic deposits to the oral cavity are exceptionally rare. The commonest tumor types metastasizing to the oral cavity include lung and breast carcinoma. Renal cell carcinoma is believed to be the third most common infra clavicular tumor to metastasize to the head and neck. We report a case where an oral cavity deposit was the initial presentation for an occult clear cell renal carcinoma. Additional therapeutic options, including immunotherapy, tyrosine kinase inhibitors, and participation in a clinical trial, should be discussed with the patient despite the poor overall prognosis.

    Adnexal carcinomas are rare and diverse cutaneous tumours. They are locally aggressive and have the potential for distant metastasis. Metastatic adnexal carcinomas are very resistant to conventional chemotherapies. Sunitinib, an oral tyrosine kinase inhibitor, is reportedly effective for the treatment of various solid cancers. Its use in adnexal carcinomas has never been reported. The first patient had metastatic clear cell hidradenocarcinoma and was stabilized over 8 months with sunitinib, before she relapsed. The second patient had a metastatic malignant hair follicle tumour (trichoblastic carcinoma) and achieved a partial remission with sunitinib, and disease stabilized after 10 months. Dynamic contrast-enhanced ultrasound (DCE-US) performed to evaluate tumour vascularization during treatment depicted a dramatic and early decrease in the tumour blood volume. Sunitinib was effective in controlling the disease in our two patients. DCE-US using linear raw data may have an early predictive value for tumour response to sunitinib. Further studies involving larger cohorts of patients are warranted in order to confirm the efficacy of sunitinib in these rare tumours.

    Juvenile fibroadenoma is an uncommon histologic variant of fibroadenoma that frequently shows a remarkable and rapid growth. The development of a carcinoma within a fibroadenoma, either in situ or invasive, is a rare condition. We encountered a 36-year-old woman with a palpable mass in the right breast. The radiologic findings were indicative of a fibroadenoma in the breast. Sonographic guided biopsy using a 14G core needle revealed the presence of ductal carcinoma in situ (DCIS) within the juvenile fibroadenoma. Focal excision was performed and the patient underwent radiation therapy in the right breast after surgery

    2011-01-01

    Full Text Available A 52-year-old woman presented with fracture upper end of the left humerus after trivial trauma and aspiration cytology from the lytic lesion in the upper humerus seen on X-ray revealed a metastatic papillary carcinoma from the thyroid. Total thyroidectomy confirmed the papillary carcinoma thyroid. Post-operatively, she was given radioactive iodine (I-131 ablation therapy for 8 years and was asymptomatic during this period; however, for the last 1 year, she has been complaining of swelling in the shoulder, which did not respond to palliative radiotherapy and rapidly increased in size. Disarticulation of the shoulder joint was performed, which showed anaplastic carcinoma on histopathological examination. Anaplastic transformation of papillary carcinoma at the metastatic sites is well documented in the literature and is rare. However, the same has not been reported at the shoulder and from India before. Although soft tissue sarcomas are most common at this site, however, the possibility of anaplastic transformation should be kept in the differential diagnosis of rapidly enlarging painful mass in a known case of metastatic thyroid carcinoma to prevent misdiagnosis.

    According to current statistics of the WHO, tuberculosis is the infectious disease that causes the most deaths worldwide. Its most common cutaneous manifestation is lupus vulgaris which is seldom diagnosed today. A 69-year old immunocompetent woman complained of a partly elevated, partly sclerotic plaque on her left thigh which had been present for more than 55 years before slowly becoming ulcerated. After biopsy and subsequent excision of the 13 cm ulcer, the diagnosis of carcinoma in lupo with lymph node metastasis was made. Cutaneous and additional nodal metastases appeared rapidly. Tuberculostatic therapy was initiated. Despite systemic chemotherapy the tumor subsequently progressed and the patient died of metastatic carcinoma in lupo 15 months after the initial diagnosis. Early diagnosis and treatment of lupus vulgaris might have prevented the development of carcinoma in lupo and ensuing metastatic death of the patient.

    Sweat gland carcinomas constitute less than 10% of all malignant tumors of the vulva, including those associated with extramammary Paget's disease (EPD). The histopathologic diagnosis of vulvar sweat gland carcinomas is difficult because of their rarity; their resemblance to metastatic carcinomas of the internal female genitalia, kidneys, and other sites; and their diversity of microscopic appearances. We report five examples of vulvar sweat gland carcinomas, two of which were associated with EPD. The other tumors included one example each of ductal eccrine adenocarcinoma, eccrine porocarcinoma, and clear cell hidradenocarcinoma. The clinical behavior of these neoplasms is correlated with their histologic types; we also discuss differential diagnosis and treatment recommendations.

    Lobular carcinomas in situ (LCIS) represent 1-2% of all breast cancers. Both significance and treatment remain widely debated, as well as the possible similarities with DCIS. Two hundred patients with pure LCIS were retrospectively analyzed in seven centres from 1990 to 2008. Median age was 52 years; 176 patients underwent breast-conserving surgery (BCS) and 24 mastectomy. Seventeen patients received whole breast irradiation (WBRT) after BCS and 20 hormonal treatment (15 by tamoxifen). With a 144-month median follow-up (FU), there were no local recurrences (LR) among 24 patients treated by mastectomy. With the same FU, 3 late LR out of 17 (17%) occurred in patients treated by BCS and WBRT (with no LR at 10 years). Among 159 patients treated by BCS alone, 20 developed LR (13%), but with only a 72-month FU (17.5% at 10 years). No specific LR risk factors were identified. Three patients developed metastases, two after invasive LR; 22 patients (11%) developed contralateral BC (59% invasive) and another five had second cancer. LCIS is not always an indolent disease. The long-term outcome is quite similar to most ductal carcinomas in situ (DCIS). The main problems are the accuracy of pathological definition and a clear identification of more aggressive subtypes, in order to avoid further invasive LR. BCS + WBRT should be discussed in some selected cases, and the long-term results seem comparable to DCIS

    Background The ability to accurately assess tumor size in ductal carcinoma in situ (DCIS) is an important clinical issue when selecting the appropriate treatment plan. Purpose To compare the accuracy of using mammography, ultrasound (US), and magnetic resonance imaging (MRI) to assess DCIS tumor size based on imaging and histopathological findings. Material and Methods Fifty-six patients with DCIS were included. Mammography, US, and MRI were reviewed, and the accuracy of the measured tumor sizes were compared with the imaging and histopathological parameters. Results If visible, tumor measurements demonstrated high reliability with the pathologically determined size, with the best results obtained using US ( k = 0.851) followed by mammography ( k = 0.815) and MRI ( k = 0.738). Tumor size assessment was significantly more accurate when the lesion was shown as a mass on US ( P = 0.003) or MRI ( P mammography was used to assess tumor size, the tumors with positive estrogen receptor status and luminal A subtype demonstrated a significantly more accurate tumor size. Conclusion The combination of US and MRI, in addition to mammography, has an important role in assessing the exact tumor extent of DCIS.

    To assess knowledge, satisfaction with information, decisional conflict and psychological morbidity amongst women diagnosed with ductal carcinoma in situ (DCIS) and to explore the factors associated with less knowledge and greater confusion about DCIS. A cross-sectional survey of women diagnosed with DCIS in Australia (N=144). This study found misunderstanding and confusion amongst women diagnosed with DCIS and a desire for more information about their breast disease. Approximately half of participants worried about their breast disease metastasizing; approximately half expressed high decisional conflict; 12% were anxious and 2% were depressed. Logistic regression analysis demonstrated that worry about dying from the breast disease was significantly associated with not knowing that DCIS could not metastasize (OR 3.9; 95% CI 1.03-14.25); and confusion about whether DCIS could metastasize was significantly associated with dissatisfaction with information (OR 12.5; 95% CI 3.8-40.2). Good communication about how DCIS differs from invasive breast cancer is essential to alleviating the confusion and worry amongst women with DCIS. Recommendations about how best to communicate a diagnosis of DCIS, including the uncertainties, are needed to guide health professionals to promote better understanding about DCIS and increase the well-being of women with DCIS.

    The utility and reliability of assessing molecular biomarkers for translational applications on pre-operative core biopsy specimens assume consistency of molecular profiles with larger surgical specimens. Whether DNA methylation in ductal carcinoma in situ (DCIS), measured in core biopsy and surgical specimens are similar, remains unclear. Here, we compared genome-scale DNA methylation measured in matched core biopsy and surgical specimens from DCIS, including specific DNA methylation biomarkers of subsequent invasive cancer. DNA was extracted from guided 2mm cores of formalin fixed paraffin embedded (FFPE) specimens, bisulfite-modified, and measured on the Illumina HumanMethylation450 BeadChip. DNA methylation profiles of core biopsies exhibited high concordance with matched surgical specimens. Within-subject variability in DNA methylation was significantly lower than between-subject variability (all Pcore biopsy and surgical specimens, 15%, and a pathway analysis of these CpGs indicated enrichment for genes related with wound healing. Our results indicate that DNA methylation measured in core biopsies are representative of the matched surgical specimens and suggest that DCIS biomarkers measured in core biopsies can inform clinical decision-making.

    Nogo-B receptor (NgBR) has been shown to be involved in endothelial cell chemotaxis and morphogenesis. However, few studies analyzing its expression in cancer cells have been performed. We examined NgBR expression in 233 patients with invasive ductal breast carcinoma (IDC) and corresponding non-malignant breast tissues (NMBT) on mRNA (real-time polymerase chain reaction) and protein levels (immunohistochemistry; IHC and western-blot analysis). NgBR expression was found also analyzed in breast cancer cell lines of varying invasiveness. NgBR expression was increased in IDC compared to NMBT on the mRNA (p=0.0007) and protein level (p=0.018). NgBR expression decreased significantly with IDC malignancy grade and correlated negatively with the Ki-67 antigen expression (r=-0.18; p=0.0005). High NgBR mRNA expression was associated with estrogen receptor negativity (p=0.0023) and the triple-negative phenotype of the tumors (p=0.0129). NgBR may be involved in IDC development, however, its role in its progression requires further research. Copyright© 2014 International Institute of Anticancer Research (Dr. John G.

    Ductal carcinoma-in situ (DCIS) is a preinvasive form of breast cancer associated with excellent outcomes after either mastectomy or breast conservation therapy. Previous studies have demonstrated declining rates of mastectomy. However, it is unclear how this pattern has changed in recent years. Women with DCIS were identified within the National Cancer Data Base. Patients treated with lumpectomy with or without radiotherapy were compared to women treated with mastectomy on the basis of demographic, clinicopathologic, and reporting facility details using χ (2) tests and multivariable logistic regression modeling to identify factors that may influence surgical choice. Changes in the proportion of women receiving contralateral prophylactic mastectomy (CPM) were assessed in a similar fashion. We identified 212,936 women diagnosed with DCIS between 1998 and 2011. Lumpectomy was performed in 68 % (144,681) of patients. Mastectomy rates initially declined from 1998 (36 %) through 2004 (28 %), before increasing again through 2011 (33 %). Younger patient age, greater medical comorbidity, more extensive disease, higher tumor grade, treatment at an academic facility, and greater distance from the reporting facility were associated with heightened use of mastectomy (all p time, particularly among younger patients, on multivariate analysis (p fashion. Further research is needed to understand the drivers of this change.

    Axillary ultrasound (AUS) with fine-needle aspiration (FNA) biopsy of abnormal lymph nodes is important for pre-operative staging and planning the surgical management of the axilla. Invasive lobular carcinoma (ILC) metastases are thought to be difficult to detect because the cells are small and on cytology resemble lymphocytes. To investigate this we directly compared the sensitivity of pre-operative axillary staging between ILC and invasive ductal carcinoma (IDC). Consecutive patients that presented in a single breast unit with pure IDC between April 2005 and December 2006 and pure ILC between January 2008 and December 2012 were retrospectively identified from pathology records. Pre-operative axillary ultrasound and FNA biopsy results were compared with post-operative histopathology from the sentinel node biopsy (SNB) or axillary lymph node dissection (ALND). A total of 275 and 142 axillae were identified in the IDC and ILC groups respectively. In the node positive patients there was no significant difference in the sensitivity of AUS (IDC vs. ILC; 58.7% vs. 52.8%). However, there was a significant difference in the sensitivity of ultrasound-guided FNA biopsy of abnormal nodes (IDC vs. ILC; 98.4% vs. 53.6%; p < 0.001). AUS has comparative sensitivities between IDC and ILC populations. In contrast, FNA biopsy of abnormal axillary nodes is clearly less sensitive in the ILC group. In these patients, who have abnormal AUS, we suggest that a core biopsy is required to improve the pre-operative staging and prevent unnecessary surgical procedures. Copyright © 2014 Elsevier Ltd.

    Tight junction proteins, including claudins, are often dysregulated during carcinogenesis and tumor progression. Moreover, the claudin expression pattern usually varies between different tumor entities. We aimed to investigate claudin expression profiles of primary and metastatic liver malignancies. We analyzed claudin-1, -2, -3, -4, and -7 expression by quantitative immunohistochemistry and real-time RT-PCR, respectively. Twenty hepatocellular carcinomas (HCCs) and liver metastases of 20 colorectal adenocarcinomas (CRLMs) and 15 pancreatic adenocarcinomas (PLMs) were studied together with paired surrounding non-tumorous liver samples and 5 normal liver samples. Strong claudin-3 and -7 immunohistochemical positivities were detected in CRLM samples, each with significantly stronger staining when compared with HCC and PLM groups. Claudin-1 protein was found highly expressed in CRLM, in contrast to lower expression in PLM and HCC. CRLMs and PLMs also were strongly positive for claudin-4, while being virtually undetectable in HCC. Claudin-2 showed strong positivity in non-tumorous liver tissue, whereas significantly weaker positivity was observed in all tumors. Differences in mRNA expression were mostly similar to those found by immunohistochemistry. In conclusion, HCC and both CRLM and PLM display distinct claudin expression profiles, which might provide better understanding of the pathobiology of these lesions and might be used for differential diagnosis.

    We present a case of a 71-year-old woman with recurrent stroke episodes due to non-bacterial thrombotic endocarditis (NBTE) leading to the diagnosis of an early-stage breast carcinoma. NBTE is associated with a variety of inflammatory states, including malignancy. NBTE presents itself with systemic embolization, mostly stroke. Treatment consists of treating the underlying condition and start of systemic anticoagulation therapy. Cardiac surgery is restricted to highly selected cases, since prognosis usually is limited by the neoplasm, which usually is in an advanced stage at time of diagnosis of NBTE. The malignancy usually is diagnosed prior to NBTE. Cases presenting with NBTE leading to the diagnosis of malignancy, however, are rarely reported. To our knowledge, we present the first case leading to the diagnosis of an early-stage breast carcinoma.

    Malignant pleural mesothelioma (MPM) is a rare malignant neoplasm of the pleura that typically affects individuals occupationally exposed to asbestos through a variety of industries. MPM presents with several CT features similar to more common pleural diseases such as metastatic pleural malignancy. The aim of this study is to differentiate malignant pleural mesothelioma from metastatic carcinoma of the pleura by pathological and radiological assessment in order to investigate accuracy of CT scan in this regard and to compare CT features of these two malignancies. Chest CT scans of 55 pleural malignancy patients including MPM and metastatic pleural malignancy were evaluated in this retrospective study. The pathologist made the definite diagnosis based on immunohistochemistry. A chest radiologist unaware of the pathology diagnosis observed all CT scans. Several parameters including pleural thickening, pleural effusion, thickening of inter lobar fissure, contralateral extension, contraction of involved hemithorax, parenchymal involvement (infiltration, nodules, fibrosis), pleural mediastinal involvement, lymphadenopathy, extrapleural invasion (hepatic, chest wall, diaphragm, intraperitoneal), and pericardial involvement were checked. Data analysis was carried out using SPSS version 16, and the ability of CT scan to differentiate malignant pleural mesothelioma and metastatic pleural diseases was investigated. Totally 29 males and 26 females were assessed in this study. Based on pathology, 17 MPM and 38 metastatic pleural malignancies were diagnosed. According to CT study, about 82% of the patients with MPM and about 79% of the patients with metastatic pleural diseases were correctly diagnosed by a radiologist. The most common findings suggestive of MPM were pleural thickening (88.2%), loculated effusion (58.8%), and thickening of the interlobar fissure (47.1%). Whereas free pleural effusion (71.7%), parenchymal infiltration (65.8%) and pleural thickening (63.2%) were

    Adenoid cystic carcinoma (ACC) is a rare cancer, and there are no standard-of-care treatments for patients with metastatic ACC. We herein report a patient with lung metastasis of ACC who achieved a favorable response to levetiracetam. A 52-year-old Japanese man was admitted to our hospital because of multiple lung metastases of ACC. We performed first-line chemotherapy with cisplatin plus gemcitabine, and subsequently oral S-1 as second-line chemotherapy, which resulted in disease progression. The patient developed symptomatic epilepsy and received levetiracetam (250 mg twice daily). At five months after the initiation of levetiracetam, chest computed tomography showed regression of the metastatic lung lesions.

    We report a case of metastatic carcinoma to the apex of the orbit in a 66-year old patient. Orbital metastasis occurred while the patient suffered from another metastatic activity especially in his bony structures. The orbital tumour caused rapid visual impairment because of compression of the optic nerve. The metastasis was treated by radiation therapy. With CT-scan, electrophysiological examination, visual field examination, and visual function we demonstrate the regression of the tumour. One year after therapy the tumor was no longer detectable. Visual function had recovered and visual fields were normally. Radiation therapy prolonged high quality life for our patient due to preservation of visual function. (authors)

    Cancer-associated fibroblasts (CAFs) are classified into various functional subtypes such as fibroblast activation protein-α (FAP-α), fibroblast specific protein-1 (FSP-1), platelet-derived growth factor receptor-α (PDGFR-α), and PDGFR-β. In this study, we compared the expression of CAF-related proteins in invasive lobular carcinoma (ILC) with those in invasive carcinoma of no special type (NST) and assessed the implications of the differences observed. Using tissue microarrays of 104 ILC and 524 invasive carcinoma (NST) cases, immunohistochemistry for CAF-related proteins [podoplanin, prolyl 4-hydroxylase, FAP-α, FSP-1/S100A4, PDGFR-α, PDGFR-β, and chondroitin sulfate proteoglycan (NG2)] was conducted. In invasive carcinoma (NST), tumor cells expressed a high level of PDGFR-α, whereas ILC tumor cells expressed high levels of podoplanin, prolyl 4-hydroxylase, FAP-α, and FSP-1/S100A4. In stromal cells of invasive carcinoma (NST), high expression levels of prolyl 4-hydroxylase, PDGFR-α, and NG2 were observed, whereas ILC stromal cells expressed high levels of FAP-α, FSP-1/S100A4, and PDGFR-β. In ILC, tumoral FSP-1/S100A4 positivity was associated with higher Ki-67 labeling index (p = 0.010) and non-luminal A type cancer (p = 0.014). Stromal PDGFR-α positivity was associated with lymph node metastasis (p = 0.011). On survival analysis of entire cases, tumoral FSP-1/S100A4 positivity (p = 0.002), stromal podoplanin positivity (p = 0.041), and stromal FSP-1/S100A4 negativity (p = 0.041) were associated with shorter disease-free survival; only tumoral FSP-1/S100A4 positivity (p = 0.044) was associated with shorter overall survival. In ILC, the expression of FAP-α and FSP-1/S100A4 was higher in both tumor and stromal cells than that observed in invasive carcinoma (NST). These results indicate that CAFs are a potential target in ILC treatment.

    To present a case report of a metastasis from cervical cancer to the maxilla, which was misdiagnosed as periapical disease and to caution clinicians that metastases could have a disguised clinical presentation that must be taken into account in the differential diagnosis of periapical disease in oncologic patients. Although metastatic tumours of the jaws are uncommon, they may mimic benign inflammatory processes and reactive lesions. The ability of metastatic lesions to mimic periapical disease is discussed and a brief review of the literature is presented, emphasizing the importance of correct diagnosis to prevent delay in diagnosing cancer. Attention should therefore be given to the patient's medical history, especially of those with a previous history of cancer, and all dental practitioners should be aware of the possibility of metastases that may be confused with periapical disease. Finally, endodontists are well placed to recognize malignant and metastatic oral lesions during the initial clinical stages, given that their treatments are usually based on frequent dental appointments and long-term follow-ups. © 2015 International Endodontic Journal.

    Angiogenesis is a critical process in the progression of advanced renal cell carcinoma. Agents targeting angiogenesis have played a primary role in the treatment of metastatic renal cell carcinoma. However, resistance to anti-angiogenesis therapy almost always occurs, and major progress has been made in understanding its underlying molecular mechanism. Axitinib and everolimus have been used extensively in patients whom have had disease progression after prior anti-angiogenesis therapy. Recently, several new agents have been shown to improve overall survival in comparison with everolimus. This review provides an in-depth summary of drugs employable in the clinical setting, the rationale to their use, and the studies conducted leading to their approval for use and provides perspective on the paradigm shift in the treatment of renal cell carcinoma. Highlighted are the newly approved agents cabozantinib, nivolumab, and lenvatinib for advanced renal cell carcinoma patients treated with prior anti-angiogenesis therapy.

    While breast lesions have characteristic cytological features, some lesions, particularly adenocarcinoma and fibroadenoma, may present with overlapping features causing erroneous diagnoses. The current study aimed to define significant cytomorphologic features predictive of fibroadenoma and adenocarcinoma, respectively. Further, we intended to evaluate the predictive characteristics for differentiation between gray zone lesions and to identify root causes contributing to misdiagnoses. First, direct smears prepared from 14 histology-confirmed fibroadenomas and 14 adenocarcinomas were reviewed and characteristics of commonly encountered morphologic features were assessed. We then retrospectively and blindly reviewed nine cytohistologic discrepant cases using the significant characteristic as a guideline, in order to assess whether these discrepant cases could be correctly categorized. Morphologic characteristics predictive of fibroadenoma included moderate cellularity, large, folded cellular sheets/aggregates, staghorn projections, smooth and round borders, monolayers, honeycomb arrangement, smaller nuclear size, and background bipolar cells. Predictive characteristics of adenocarcinoma included high cellularity, loose cohesive sheets/aggregates, pointed projections, irregular borders, larger nuclear size, irregular nuclear membrane, prominent nucleoli, and single atypical epithelial cells. Retrospective, blind review correctly re-classified seven out of nine cytohistologic discrepant cases, including five false negative cases and two false positive cases. Root causes contributing to the misdiagnoses were large branching sheets of carcinoma mimicking folded sheets of fibroadenoma; fibroblasts mimicking myoepithelial cells; apocrine cells mimicking carcinoma cells; and not recognizing the loose myxoid matrix presenting as soap bubbles in fibroadenoma. In conclusion, this study identified significant characteristics that can assist in achieving accurate diagnosis in a

  6. Reactive Hypertrophy of an Accessory Spleen Mimicking Tumour Recurrence of Metastatic Renal Cell Carcinoma

    Full Text Available De novo occurrence of an accessory spleen after splenectomy is worth noting for two reasons. First, it is known that splenectomy can cause reactive hypertrophy of initially inactive and macroscopically invisible splenic tissue. Second, it can mimic tumour recurrence in situations in which splenectomy has been performed for oncological reasons. This might cause difficulties in differential diagnosis and the clinical decision for reoperation. We report the case of a patient with suspected recurrence of renal cell carcinoma after total pancreatectomy and splenectomy for metastatic renal cell carcinoma, which finally revealed an accessory spleen as the morphological correlate of the newly diagnosed mass in the left retroperitoneum.

    Full Text Available An 84-year-old gentleman presented with onset of gross hematuria in September 2010. Follow-up investigations revealed T1 superficially invasive, poorly differentiated, papillary urothelial carcinoma. He subsequently had GreenLight laser for BPH and bladder neck contracture on two occasions. He developed a right hydrocele 16 months after initial presentation and during his hydrocelectomy, a rock-hard right epididymis and testicle were discovered. Pathology revealed metastatic urothelial carcinoma replacing nearly the entire testis with lymphovascular invasion.

    A retrospective study of two methods of ovarian ablation as primary therapy for metastatic carcinoma of the breast was carried out using records from this cancer institute. Sixty-one radiation and 97 surgical ovarian ablations, performed from 1972 to 1977, were assessed. Over-all response was similar for the surgical and irradiation groups. Survival from the time of ovarian ablation was greater in both groups in those who responded positively than in those who did not. Factors other than estrogen receptor status can determine the response of patients with metastatic carcinoma of the breast to ovarian ablation. The results indicate that clinical determinates and not the efficiency of one method over the other should be the main criteria for choosing between ovarian ablation by irradiation or by oophorectomy

    Overtreatment is a common concern for patients with ductal carcinoma in situ (DCIS), but this entity is difficult to distinguish from invasive breast cancers in administrative claims data sets because DCIS often is coded as invasive breast cancer. Therefore, the authors developed and validated algorithms to select DCIS cases from administrative claims data to enable outcomes research in this type of data. This retrospective cohort using invasive breast cancer and DCIS cases included women aged 66 to 70 years in the 2004 through 2011 Texas Cancer Registry (TCR) data linked to Medicare administrative claims data. TCR records were used as "gold" standards to evaluate the sensitivity, specificity, and positive predictive value (PPV) of 2 algorithms. Women with a biopsy enrolled in Medicare parts A and B at 12 months before and 6 months after their first biopsy without a second incident diagnosis of DCIS or invasive breast cancer within 12 months in the TCR were included. Women in 2010 Medicare data were selected to test the algorithms in a general sample. In the TCR data set, a total of 6907 cases met inclusion criteria, with 1244 DCIS cases. The first algorithm had a sensitivity of 79%, a specificity of 89%, and a PPV of 62%. The second algorithm had a sensitivity of 50%, a specificity of 97%. and a PPV of 77%. Among women in the general sample, the specificity was high and the sensitivity was similar for both algorithms. However, the PPV was approximately 6% to 7% lower. DCIS frequently is miscoded as invasive breast cancer, and thus the proposed algorithms are useful to examine DCIS outcomes using data sets not linked to cancer registries.

    Nipple-sparing mastectomy (NSM) is increasingly popular for the treatment of select breast cancers and prophylactic mastectomy. This study aimed to analyze the authors' 11-year experience with NSM and breast reconstruction in cases of ductal carcinoma in situ (DCIS) with an emphasis on indications, complications, and cancer recurrence rate. Between January 2000 and December 2010, 41 NSMs were performed in 41 women for DCIS. The mean age of the women was 49.7±8.7 years (range, 33-66 years). The indications for NSM were tumor size greater than 3 cm (18 cases), multifocal tumor (16 cases), and tumor recurrence (7 cases). In all cases, the tumor was located more than 2 cm from the nipple-areola complex (NAC), as shown by preoperative radiologic imaging. Histologic results, secondary NAC resection, complications, and cancer recurrence rates were recorded. The NAC was lost in seven cases (17%) due to postoperative necrosis. In another 10 patients (25%), the NAC was secondarily removed due to proximity of the tumor to the resection margin. Five patients were lost to follow-up evaluation (12%). The authors report the long-term follow-up data for the remaining 19 patients (46%). In this group, they observed one local recurrence (5.3%) and one case of ovarian cancer. Despite the low locoregional recurrence rate for DCIS, NSM remains controversial because of the nipple necrosis observed and the irradical tumor excisions. Given the ethical impossibility of conducting randomized controlled studies to compare NSM with conventional or skin-sparing mastectomy in DCIS, only long-term follow-up evaluations can demonstrate the safety of NSM.

    Cancer progression is linked to a partially dedifferentiated epithelial cell phenotype. The signaling pathways Wnt, Hedgehog, TGF-β and Notch have been implicated in experimental and developmental epithelial mesenchymal transition (EMT). Recent findings from our laboratory confirm that active Wnt/β-catenin signaling is critically involved in invasive ductal carcinomas (IDCs) of breast. In the current study, we analyzed the expression patterns and relationships between the key Wnt/β-catenin signaling components- E-cadherin, Slug and GSK3β in IDCs of breast. Of the 98 IDCs analyzed, 53 (54%) showed loss/or reduced membranous staining of E-cadherin in tumor cells. Nuclear accumulation of Slug was observed in 33 (34%) IDCs examined. Loss or reduced level of cytoplasmic GSK3β expression was observed in 52/98 (53%) cases; while 34/98 (35%) tumors showed nuclear accumulation of GSK3β. Statistical analysis revealed associations of nuclear Slug expression with loss of membranous E-cadherin (p = 0.001); nuclear β-catenin (p = 0.001), and cytoplasmic β-catenin (p = 0.005), suggesting Slug mediated E-cadherin suppression via the activation of Wnt/β-catenin signaling pathway in IDCs. Our study also demonstrated significant correlation between GSK3β nuclear localization and tumor grade (p = 0.02), suggesting its association with tumor progression. The present study for the first time provided the clinical evidence in support of Wnt/β-catenin signaling upregulation in IDCs and key components of this pathway - E-cadherin, Slug and GSK3β with β-catenin in implementing EMT in these cells

    Full Text Available Abstract Background It's well recognized that X-linked inhibitor of apoptosis (XIAP was the most potent caspase inhibitor and second mitochondria-derived activator of caspase (Smac was the antagonist of XIAP. Experiments in vitro identified that down regulation of XIAP expression or applying Smac mimics could sensitize breast cancer cells to chemotherapeutics and promote apoptosis. However, expression status and biologic or prognostic significance of XIAP/Smac in breast invasive ductal carcinoma (IDC were not clear. The present study aimed to investigate relationship among expression status of XIAP/Smac, apoptosis index (AI, clinicopathologic parameters and prognosis in IDC. Methods Immunohistochemistry and TUNEL experiment were performed to detect expression of XIAP, Smac, ER, PR, HER2 and AI in 102 cases of paraffin-embedded IDC samples respectively. Expression of XIAP/Smac were also detected in limited 8 cases of fresh IDC specimens with Western blot. Results Positive ratio and immunoscore of XIAP was markedly higher than Smac in IDC (P P s = 0.265, P = 0.017. The present study first revealed that XIAP positive nuclear labeling (XIAP-N, but not cytoplasmic staining (XIAP-C, was the apoptotic marker correlated significantly with patients' shortened overall survival (P = 0.039. Survival analysis demonstrated that XIAP-N was a new independent prognostic factor except for patient age and lymph node status. Conclusion Disturbed balance of expression between XIAP and Smac probably contributed to carcinogenesis and XIAP positive nuclear labeling was a new independent prognostic biomarker of breast IDC.

    To investigate whether mass stiffness measured by shear-wave elastography (SWE) can predict the histological upgrade of ductal carcinoma in situ (DCIS) confirmed through ultrasound (US)-guided core needle biopsy (CNB). The institutional review board approved this study and informed consent was waived. A database search revealed 120 biopsy-confirmed DCIS in patients who underwent B-mode US and SWE prior to surgery. Clinicopathologic results, B-mode findings, size on US, and mean and maximum elasticity values on SWE were recorded. Associations between upgrade to invasive cancer and B-mode US findings, SWE information, and clinical variables were assessed using univariate, multivariate logistic regression, and multiple linear regression analysis. The overall upgrade rate was 41.7 % (50/120). Mean stiffness value (P = .014) and mass size (P = .001) were significantly correlated with histological upgrade. The optimal cut-off value of mean stiffness value, yielding the maximal sum of sensitivity and specificity, was 70.7 kPa showing sensitivity of 72 % and specificity of 65.7 % for detecting invasiveness. Qualitative elasticity colour scores were significantly correlated with the histological upgrade, mammographic density, and B-mode category (P < .04). Mean stiffness values evaluated through SWE can be utilized as a preoperative predictor of histological upgrade to invasive cancer in DCIS confirmed at US-guided needle biopsy. • Higher stiffness values were noted in invasive cancer than DCIS. • Qualitative SWE colour scores significantly correlated with the histological upgrade. • Qualitative SWE colour scores had excellent interobserver agreement.

    Purpose: To examine the outcomes of Southeast Asian (SEA) women with low-risk ductal carcinoma in situ (DCIS) treated with breast-conserving surgery (BCS) and adjuvant radiation therapy. Methods and Materials: Retrospective chart reviews of patients treated with BCS for DCIS from 1995 to 2011 were performed. Patients meeting the selection criteria from Eastern Cooperative Oncology Group 5194 were included. Most patients received adjuvant radiation therapy (RT) consisting of whole-breast RT delivered to 50 Gy followed by a 10-Gy boost to the tumor bed. Results: Of 744 patients with pathologic diagnosis of pure DCIS identified, 273 met the selection criteria: low-intermediate grade (LIG), n=219; high grade (HG), n=54. Median follow-up for these patients was 60 months. There were 8 ipsilateral breast tumor recurrences (IBTRs) in total, 7 of which were DCIS. The estimated actuarial IBTR rates at 5 and 10 years for the entire cohort are 1.8% and 4.3%, respectively. Of the 219 patients with LIG DCIS, 210 received RT and 9 did not. There were 7 IBTRs in LIG DCIS, 2 among the 9 patients who did not receive RT. The IBTR rates in LIG DCIS at 5 and 10 years are 2.3% and 4.2%, respectively. All patients with HG DCIS received RT. There was only 1 IBTR occurring beyond 5 years, giving an estimated IBTR rate of 4.5% at 10 years. Conclusions: SEA women with screen-detected DCIS have exceedingly low rates of IBTR after BCS, comparable to that observed in reports of similar patients with low-risk DCIS treated with adjuvant radiation

    To explore quality-of-life (QOL) issues considered important when deciding on treatment for ductal carcinoma in situ (DCIS). Breast Cancer Network of Australia members diagnosed with DCIS in the past 5 years (self-identified) participated in an online survey (Sep-Nov 2015). From a list of 74 QOL issues, participants selected all issues they experienced during DCIS diagnosis, treatment or recovery, then the issues they felt important to making a DCIS treatment decision, and completed the Health Literacy Questionnaire (HLQ). Associations between QOL issues and self-reported treatment received were assessed with χ 2 tests. The primary analysis included 38 participants treated with breast-conserving surgery (n = 15), mastectomy (n = 23), and/or radiotherapy (n = 14). Fatigue-related symptoms (82%) and "fear of progression" (50%) were the most frequently-experienced issues. When deciding on DCIS treatment, the most important consideration was "fear of progression" (50%). A higher proportion of mastectomy (compared to non-mastectomy) patients considered "difficultly looking at yourself naked" (p = 0.03). Radiotherapy (compared to non-radiotherapy) patients were more likely to consider "feeling unwell" important (p = 0.006). Results were similar in a sensitivity analysis involving all 101 respondents (i.e., including 63 respondents who reported receiving chemotherapy, endocrine therapy, and/or Herceptin, suggesting that they may have been treated for invasive breast cancer). Health literacy was high across all nine HLQ scales. Fear of progression is a key consideration in DCIS treatment decision making for women with high health literacy. QOL treatment considerations differed by treatments received. Women diagnosed with DCIS may benefit from evidence about QOL to inform treatment decision making.

    Pure populations of tumor cells are essential for the identification of tumor-associated proteins for the development of targeted therapy. In recent years, laser capture microdissection (LCM) has been used successfully to obtain distinct populations of cells for subsequent molecular analysis. The polycomb group (PcG) protein, enhancer of zeste homolog 2 (EzH2), a methyl-transferase that plays a key role in -transcriptional gene repression, is frequently overexpressed in several malignant tumors. High levels of EzH2 are often associated with advanced disease stage in many solid tumors; however, its role in the pathogenesis of pancreatic ductal adeno-carcinoma (PDAC) is poorly understood. Because of the limited sample availability and the absence of in vitro amplification steps for proteins, the use of LCM for proteomics studies largely depends on highly sensitive protein detection methods. Here, we developed a faster and sensitive Western blot protocol and validated it for the detection of EzH2 in ∼2,000 cells. Initially, cultured PANC-1 cells were used to optimize protein electrophoresis and western blotting conditions. Gradient gel electrophoresis in combination with optimized antibody concentrations, and a sensitive chemiluminescent assay provided a strong signal. In order to further confirm the role of EzH2 in PDAC, employing siRNA-mediated gene silencing via long lasting plasmid vectors containing shRNA, we investigated the potential role of EzH2 gene silencing in pancreatic cancer regression. Positive correlation of EzH2 expression was observed with advanced stage, serous histology, and increasing grade in pancreatic cancer patient tissues. Further EzH2 knockdown resulted in decreased cell growth and invasiveness. The findings of this study emphasize that western blotting of a LCM-generated pure population of cancer cells may be a valuable technique for the study of tumor-specific proteins.

    Purpose: Evaluation of the sensitivity and specificity of glypican3 (GPC3) in differentiating hepatocellular carcinoma (HCC) from metastatic carcinomas of the liver in cell block material. Patients and methods: Sixty cell blocks were prepared from liver FNAs performed in the radiodiagnosis department, National Cancer Institute, in the period between August 2011 and May 2012. Cases diagnosed as hepatocellular carcinoma, or metastatic carcinoma were included in the study. Cell block sections were stained with anti GPC-3. Sensitivity, specificity, and positive and negative predictive values, of GPC3 were calculated. The final diagnosis was based on the triple approach of clinical data, radiological findings, as well as cytomorphologic features aided by GPC-3 results. Results: 70% of cases were diagnosed as HCC, and 30% as metastatic carcinomas. 95.2% of HCC cases expressed GPC3. Poorly differentiated cases showed the highest GPC3 sensitivity (100%), followed by moderately differentiated cases (96.5%), while well differentiated cases expressed GPC3 in 90% of cases. 83.3% of metastatic carcinomas were negative for GPC3. In this study, sensitivity of GPC-3 in HCC was 95.2%, specificity was 83.3%, positive and negative predictive values were 93% and 88.2% respectively, and total accuracy was 91.7%. Conclusion: Immunocytochemical staining for GPC3 in cell block material is a highly sensitive and specific method capable of distinguishing HCC from the vast majority of metastatic carcinomas of the liver

    This report describes the gross, histological, and immunohistochemical features of medullary thyroid carcinoma (MTC) with pulmonary metastases in a young dog. Sheets of pleomorphic cells supported by fibrous stroma characterized the primary mass, while metastatic nodules had a neuroendocrine pattern. Despite differing histologic features, all masses showed marked immunoreactivity against calcitonin and multiple neuroendocrine markers consistent with MTC. Although MTC is a well-recognized entity, it may be difficult to distinguish this mass from other thyroid neoplasms, necessitating immunohistochemical characterization.

    Full Text Available Metastasis to the breast from an extra-mammary primary is a rare phenomenon; metastasis from gastric carcinoma to the breast is extremely so. We report a case who initially presented as mucin-secreting and signet-ring cell tumor of the ovary, and after an interval of 8 months with breast and chest wall metastatic nodules. The covert gastric primary eluded the oncologists at both presentations.

    Indium is generally presumed to localize in the bone marrow within the erythroid cell line. Fibrosis, inflammation, lymphoma, extended field radiation, chemotherapy, or combinations of both treatment modalities generally depress the uptake of indium by the marrow in a complex fashion. We report a case of metastatic breast carcinoma and pancytopenia in which the In-111 scan appeared qualitatively similar to a Tc-99m MDP bone scan. Findings were confirmed by bone marrow biopsy

    Previously, 50% of patients with breast ductal carcinoma in situ (DCIS) had more than one nuclear grade, and neither worst nor predominant nuclear grade was significantly associated with development of invasive carcinoma. Here, we used image analysis in addition to histologic evaluation to determine if quantification of nuclear features could provide additional prognostic information and hence impact prognostic assessments. Nuclear image features were extracted from about 200 nuclei of each of 80 patients with DCIS who underwent lumpectomy alone, and received no adjuvant systemic therapy. Nuclear images were obtained from 20 representative nuclei per duct, from each of a group of 5 ducts, in two separate fields, for 10 ducts. Reproducibility of image analysis features was determined, as was the ability of features to discriminate between nuclear grades. Patient information was available about clinical factors (age and method of DCIS detection), pathologic factors (DCIS size, nuclear grade, margin size, and amount of parenchymal involvement), and 39 image features (morphology, densitometry, and texture). The prognostic effects of these factors and features on the development of invasive breast cancer were examined with Cox step-wise multivariate regression. Duplicate measurements were similar for 89.7% to 97.4% of assessed image features. For the pooled assessment with ~200 nuclei per patient, a discriminant function with one densitometric and two texture features was significantly (p < 0.001) associated with nuclear grading, and provided 78.8% correct jackknifed classification of a patient's nuclear grade. In multivariate assessments, image analysis nuclear features had significant prognostic associations (p ≤ 0.05) with the development of invasive breast cancer. Texture (difference entropy, p < 0.001; contrast, p < 0.001; peak transition probability, p = 0.01), densitometry (range density, p = 0.004), and measured margin (p = 0.05) were associated with

    Full Text Available The primary carcinoma may secondarily invade bone tissue through direct extensions, blood circulation or lymphatic transportation particulary when it is arising from breast, prostate, kidney, thyroid and lung. Metastatics tumors of bone are more common than primary tumor of bone. The most common tumor, which metastasizes into bone, is the breast adenocarcinoma. Some metastatic tumors of bone including the breast cancer, may appear only as a destructive lesion, while prostatic carcinoma is osteoblastoma. The metastasis is mostly appeared in skull, vertebrae, pelvic, femur and humerus bones. The first metastatic syndrome is usually the affected bone pain and pathologic fractures are commonly caused by osteometastasis

    Brain metastasis is an uncommon but increasing manifestation of ovarian epithelial carcinoma and neuropathologists' collective experience with these tumors is limited. We present clinicopathological characteristics of 13 cases of brain metastases from ovarian epithelial carcinoma diagnosed at two academic institutions. The mean ages at diagnosis of the ovarian carcinoma and their subsequent brain metastases were 58.7 and 62.8 years, respectively. At the time of initial diagnosis of ovarian carcinoma the majority of patients had an advanced stage and none had brain metastases as their first manifestation of malignancy. Brain metastases tended to be multiple with ring-enhancing features on neuroimaging. Primary tumors and their brain metastases were all high-grade histologically and the histologic subtypes were: nine high-grade serous carcinoma (HGSC) cases, two clear cell carcinoma (CCC) cases and a single case each of carcinosarcoma and high-grade adenocarcinoma. A recommended histo- and immunopathological approach to these tumours are provided to aid neuropathologists in the recognition and classification of metastatic ovarian carcinoma to the brain. © 2014 Japanese Society of Neuropathology.

    Full Text Available Abstract Background Lobular breast carcinoma usually shows poor responsiveness to chemotherapies and often lacks targeted therapies. Since FGFR1 expression has been shown to play pivotal roles in primary breast cancer tumorigenesis, we sought to analyze the status of FGFR1 gene in a metastatic setting of lobular breast carcinoma, since promising FGFR1 inhibitors has been recently developed. Methods Fifteen tissue metastases from lobular breast carcinomas with matched primary infiltrative lobular breast carcinoma were recruited. Eleven cases showed loco-regional lymph-nodal and four haematogenous metastases. FGFR-1 gene (8p12 amplification was evaluated by chromogenic in situ hybridization (CISH analysis. Her-2/neu and topoisomerase-IIα gene status was assessed. E-cadherin and Hercept Test were also performed. We distinguished amplification (>6 or cluster of signals versus gains (3–6 signals of the locus specific FGFR-1 gene. Results Three (20% primary lobular breast carcinomas showed >6 or cluster of FGFR1 signals (amplification, six cases (40% had a mean of three (range 3–6 chromogenic signals (gains whereas in 6 (40% was not observed any abnormality. Three of 15 metastasis (20% were amplified, 2/15 (13,4% did not. The ten remaining cases (66,6% showed three chromogenic signals. The three cases with FGFR-1 amplification matched with those primary breast carcinomas showing FGFR-1 amplification. The six cases showing FGFR-1 gains in the primary tumour again showed FGFR-1 gains in the metastases. Four cases showed gains of FGFR-1 gene signals in the metastases and not in the primary tumours. Her-2/neu gene amplification was not observed in all cases but one (6% case. Topoisomerase-IIα was not amplified in all cases. Conclusions 1 a subset of metastatic lobular breast carcinoma harbors FGFR-1 gene amplification or gains of chromogenic signals; 2 a minor heterogeneity has been observed after matching primary and metastatic carcinomas; 3 in the

    The aim of the present study was to verify the effects of regorafenib on apoptosis and metastatic potential in TSGH 8301 human bladder carcinoma cells in vitro. Cells were treated with different concentration of regorafenib for different periods of time. Effects of regorafenib on cell viability, apoptosis pathways, metastatic potential, and expression of metastatic and anti-apoptotic proteins were evaluated with the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium (MTT) assay, flow cytometry, cell migration and invasion assay, and western blotting. We found regorafenib significantly reduced cell viability, cell migration and invasion, and expression of metastatic and anti-apoptotic proteins. In addition, regorafenib significantly induced accumulation of sub-G 1 phase cells, loss of mitochondrial membrane potential, and expression of active caspase-3 and caspase-8. These results show that regorafenib not only induces apoptosis, but also inhibits metastatic potential in bladder cancer TSGH 8301 cells in vitro.

    Gene copy number variations (CNVs) have been reported to be frequent in renal cell carcinoma (RCC), with potential prognostic value for some. However, their clinical utility, especially to guide treatment of metastatic disease remains to be established. Our objectives were to assess CNVs on a panel of selected genes and determine their clinical relevance in patients who underwent treatment of metastatic RCC. The genetic assessment was performed on frozen tissue samples of clear cell metastatic RCC using quantitative multiplex polymerase chain reaction of short fluorescent fragment method to detect CNVs on a panel of 14 genes of interest. The comparison of the electropherogram obtained from both tumor and normal renal adjacent tissue allowed for CNV identification. The clinical, biologic, and survival characteristics were assessed for their associations with the most frequent CNVs. Fifty patients with clear cell metastatic RCC were included. The CNV rate was 21.4%. The loss of CDKN2A and PLG was associated with a higher tumor stage (P relevance, especially those located on CDKN2A, PLG, and ALDOB, in a homogeneous cohort of patients with clear cell metastatic RCC.

    2017-04-01

    Full Text Available Objectives: Lymphovascular invasion (LVI is a pathologic, microscopic finding associated with invasive cancer, and is a poor prognostic indicator, but has no reported imaging findings. This report presents the first documented case of LVI with seen by imaging. Linear branching microcalcifications were identified on mammography and clumped enhancement was noted on MRI, both imaging findings that are highly predictive of ductal carcinoma in situ (DCIS. Methods: Ultrasound guided core biopsy of the dominant mass was performed, confirming invasive ductal malignancy. Stereotactic biopsy performed on the microcalcifications was initially interpreted by pathology as DCIS. Results: Patient underwent mastectomy. Pathologic evaluation of the surgical specimen confirmed the invasive ductal malignancy. Microcalcifications were re-evaluated with immunohistochemistry (IHC and re-classified as LVI. Radiology images and IHC stains are shown. Conclusion: This is the first report of LVI identified by imaging with findings that mimicked DCIS and initially mis-identified as DCIS by pathology as well. The implications of this overlap in radiologic appearance are discussed.

  10. A comprehensive review of 5-fluorouracil and leucovorin in patients with metastatic colorectal carcinoma.

    Colorectal carcinoma is the third leading cause of cancer-related death. The primary treatment for patients with metastatic colorectal carcinoma is systemic chemotherapy with 5-fluorouracil (5-FU) and leucovorin (LV), a biomodulator of 5-FU that has been shown to enhance its activity. Optimal dosing and administration strategies remain to be determined. This article is a review of recent studies reporting on the use of high dose and low dose LV as a biomodulator of 5-FU in patients with advanced colorectal carcinoma. Studies of LV plus 5-FU demonstrated response rates of 7-58% in patients who had not received prior chemotherapy. A survival advantage was recorded in some trials. LV plus 5-FU produces mild and transient hematologic toxicity. The most common toxicities from LV plus 5-FU were gastrointestinal and schedule-dependent, but generally resolved within a few days. The combination of LV and 5-FU provides a favorable treatment regimen for patients with metastatic colorectal carcinoma. Growing evidence suggests that altering the dose and schedule of both LV and 5-FU can impact positively on the response rate. However, controversy remains regarding the optimal dosing regimen. Therefore, continued study of LV plus 5-FU is urged and a favorable impact on survival is requisite before definitive conclusions are drawn, particularly in relation to LV dosage.

    A case of aural carcinoma with chondroid metaplasia at metastatic foci in an 8-year-old male pug is described. Multiple metastases in both lungs and the right submandibular, parotid, retropharyngeal, cervical and prescapular lymph nodes were detected. Histologically, the skin of the right ear canal appeared to be diffusely infiltrated by cords and nests of neoplastic epithelial cells, showing multifocal contiguity with the overlying hyperplastic squamous epithelium. Most of the carcinomatous cells were arranged in a glandular-like pattern, with formation of lumens containing epithelial cells attached to the peripheral cell layer by elongated intercellular bridges. Scattered foci of keratinization with central accumulations of compact, laminated keratin were also observed, and histochemical stains failed to detect mucinous secretory material. Even though histological and histochemical findings were compatible with a diagnosis of acantholytic squamous cell carcinoma, CAM5.2 immunostaining was detectable in the majority, although not all, neoplastic cells, confirming a diagnosis of poorly differentiated ceruminous gland carcinoma. Pulmonary metastatic nodules revealed multifocal areas of cartilaginous metaplasia with apparent transition of carcinomatous cells to chondroid cells, showing nuclear atypia and focal cytokeratin immunostaining. Carcinomatous cells surrounding chondroid areas also revealed focal vimentin and S100 immunoreactivity. Histological evidence of transition between the two components, as well as the presence of intermediate cells displaying both epithelial and mesenchymal immunohistochemical features, strongly indicated a final diagnosis of carcinosarcoma, in which chondrosarcomatous elements were derived from carcinoma cells. © 2011 The Authors.

    A 72-year-old man was referred to our hospital for treatment of an ulcer that had been growing on his back for 10 years. Physical examination showed an ulcerated tumor from the neck to the back and swollen cervical lymph nodes. The tumor size was 12×9 cm. Histology of the biopsy showed a nodular and morpheic basal cell carcinoma (BCC). A chest computed tomography (CT) scan showed multiple lung tumors. CT-guided biopsy of the lung and the cervical lymph node revealed metastatic basal cell carcinoma (MBCC). The primary skin tumor was resected and a total of 10 courses of cisplatin (25 mg/m 2 /day×75%) and adriamycin (50 mg/m 2 ×75%) were administered for metastatic basal cell carcinoma (MBCC). The patient died 5 years and 3 months after his first visit. Autopsy revealed MBCC in the lung, kidney, pancreas, several lymph nodes, liver and bone. A portion of the tumor cells were composed of squamoid cells with eosinophilic cytoplasm, large nuclei, lack of the characteristic peripheral palisading and retraction artifacts, and variable cytoplasmic keratinization. These pathological findings were compatible with basosquamous cell carcinoma. Chemotherapy was effective for MBCC in this patient.

    Full Text Available Introduction. Rectal large cell neuroendocrine carcinoma (LCNEC is a poorly differentiated neoplasm that is very rare and belongs within the poorest prognostic subgroup among primary colorectal neoplasms. Here, we describe a case of LCNEC of the rectum, which highlights the aggressive clinical course and poor prognosis associated with this disease. Case Presentation. We report a case of a 63-year-old male who presented to our hospital with a one-month history of lower abdominal pain, constipation, and weight loss. A computed tomography (CT scan of the chest, abdomen, and pelvis revealed a rectal mass as well as metastatic disease of the liver and lung. Flexible sigmoidoscopy revealed a fungating, ulcerated and partially obstructing rectal mass located 6 cm from the anal verge. This mass was biopsied and pathological examination of the resected specimen revealed features consistent with a large cell neuroendocrine carcinoma. Conclusion. Rectal large cell neuroendocrine carcinomas are rare and have a significantly worse prognosis than adenocarcinomas. At diagnosis, a higher stage and metastatic disease are likely to be found. It is important to differentiate large cell, poorly differentiated neuroendocrine carcinomas from adenocarcinomas of the colon and rectum pathologically because patients may benefit from alternative cytotoxic chemotherapeutic regimens.

    Full Text Available Background & Objective: Nasopharyngeal carcinoma (NPC is an epithelial neoplasm with high occurrence rates in southern China. The disease often metastasizes to regional lymphnodes at a very early stage. Local recurrences and metastasis occur frequently in patients with NPC and are a leading cause of death, despite improvements on treatment modalities. The molecular mechanism underlying the metastasis of nasopharyngeal carcinoma remains poorly understood, however, and requires additional elucidation. The aim of this study was to explore possible NPC gene candidates that may play key roles in NPC metastasis. Methods: Subtractive suppression hybridization (SSH was performed to isolate differentially expressed clones between the metastatic 5-8F and non-metastatic 6-10B nasopharyngeal carcinoma cell lines. Differentially expressed clones were screened and confirmed by reverse Northern blotting. The sequences of cDNA fragments were subsequently analyzed and compared to known sequences in Genbank. Results & Discussion: The SSH library contained thousands of positive clones. Random analysis of 300 clones by PCR demonstrated that 269 clones contained inserted fragments. Reverse Northern blot confirmed that 20 out of 192 clones examined were significantly up-regulated in the 5-8F cell line. Among these 20 clones, 16 were previously identified genes (flotilin-2, ezrin, pim-3, fli-1, mel, neugrin, znf216, ASB1, raly, UBE2A, keratin6A, TMED7, EIF3S9, FTL, two ribosomal proteins RPL21 and RPL16, two were predicted genes (c9orf74 and MDS006, and two sequences shared no homology with known genes listed in GenBank and may represent novel genes. The proposed functions of the genes identified in this study include cell signal transduction, cell survival, transcription regulation, cell mobility, protein synthesis, and DNA damage repair. Flotillin-2, fli-1, pim-3 and ezrin have previously been reported to be associated with tumor metastasis and progression. The

    Seventeen patients with carcinoma and three patients with benign lesions of the head were studied by acupuncture-point injection combined with intratumor injection of radionuclide P-32 for treatment of metastatic carcinoma. The metastatic cervical nodules shrank to half their original sizes within 2-3 weeks in five cases of nasopharyngeal carcinoma. The injected dose ranged from 0.222 to 0.421 mCi, approximately 10 times less than that given by the ordinary method. The acupuncture points are selected according to the Theory of Channels and Collaterals of Chinese traditional medicine. The mechanism of therapeutic action of radionuclide P-32 is possibly by the delivery of destructive ionizing radiation from beta emission properties of P-32. This method appears to offer a low-dose means of P-32 treatment of metastatic carcinoma

    Full Text Available Cutaneous metastasis may correspond to the initial clinical presentation of hidden internal malignancies. In patients presenting said neoplasia, clinical manifestations of breast cancer reaches 23.9%. Considering that neoplastic alopecia appears as an unusual pattern of the said metastasis, this report describes a case of such uncommon neoplastic alopecia which presents itself as a cutaneous metastasis of rapid progression in a patient with prior breast cancer history. We present a 47-year-old female patient reporting lesions at the scalp, and who was asymptomatic with a 1-year evolution. The patient reported prior breast cancer history and presence of lung metastasis, and was undergoing chemotherapy at the time of consultation. A dermatological evaluation showed only a nodular lesion with erythematous surface and a diameter measuring about 4 cm, firm in consistency, and immovable. She was routed to the Department of Dermatological Surgery, and the results from histopathology were consistent with a diagnosis of metastatic breast adenocarcinoma. Neoplastic alopecia appears as an unusual form of cutaneous metastasis which is predominantly described in association with breast cancer. The lesion’s clinical features play a crucial role at the differential diagnosis, as the presence of erythema could distinguish neoplastic alopecia from alopecia areata. The existence of cutaneous metastasis leads to unfavorable outcomes. As a conclusion, cutaneous evaluation of patients is essential for treating visceral metastases, since the forms of cutaneous metastasis are diverse and can also affect the scalp.

    Full Text Available Neuroendocrine carcinoma of the breast (NECB is a subtype of breast cancer. The diagnostic criteria of primary NECB were established in 2003 and updated in 2012. It is a rare entity, and few studies have reported the histogenesis, immunohistochemistry for a pathological diagnosis, clinical behavior, therapeutic strategies, and the prognostic factors. Because of the rarity of this disease, consistent diagnostic criteria will remind physicians of this disease when making a differential diagnosis to enable a timely diagnosis and prompt treatment. Herein, we report a case of primary NECB who presented with a history of right hip pain arising from an osteolytic lesion in the right acetabulum and ischium. The course of investigation started with metastasis in the right hip and concluded with a diagnosis of NECB. In addition to the case report, we also conducted a literature review.

    At time of presentation, fewer than 10% of patients have metastatic breast cancer. The most common sites of metastasis in order of frequency are bone, lung, pleura, soft tissue, and liver. Breast cancer metastasis to the uterus or gallbladder is rare and has infrequently been reported in the English literature. A 47 year old female with a recent history of thrombocytopenia presented with abnormal vaginal bleeding. Pelvic ultrasound revealed multiple uterine fibroids and endometrial curettings revealed cells consistent with lobular carcinoma of the breast. Breast examination revealed edema and induration of the lower half of the right breast. Biopsy of the right breast revealed invasive lobular carcinoma. Bone marrow aspiration obtained at a previous outpatient visit revealed extensive involvement by metastatic breast carcinoma. Shortly after discharge, the patient presented with acute cholecystitis and underwent cholecystectomy. Microscopic examination of the gallbladder revealed metastatic infiltrating lobular carcinoma. The final diagnosis was invasive lobular carcinoma of the right breast with metastasis to the bone marrow, endometrium, gallbladder, regional lymph nodes, and peritoneum. The growth pattern of invasive lobular carcinoma of the breast is unique and poses a challenge in diagnosing the cancer at an early stage. Unlike other types of breast cancer, it tends to metastasize more to the peritoneum, ovary, and gastrointestinal tract. Metastasis to the endometrium or gallbladder is rare. Metastatic spread should be considered in the differential diagnosis of patients with invasive lobular breast carcinoma presenting with abnormal vaginal bleeding or acute cholecystitis.

    Full Text Available Abstract Background The incidence of ductal carcinoma in situ (DCIS has increased markedly in recent decades. In the past, mastectomy was the primary treatment for patients with DCIS, but as with invasive cancer, breast-conserving surgery followed by radiation therapy (RT has become the standard approach. We present the final results of a multi-institutional retrospective study of an Italian Radiation Oncology Group for the study of conservative treatment of DCIS, characterized by a very long period of accrual, from February 1985 to March 2000, and a median follow-up longer than 11 years. Methods A collaborative multi-institutional study was conducted in Italy in 10 Radiation Oncology Departments. A consecutive series of 586 women with DCIS histologically confirmed, treated between February 1985 and March 2000, was retrospectively evaluated. Median age at diagnosis was 55 years (range: 29–84; 32 patients were 40 years old or younger. All women underwent conservative surgery followed by whole breast RT. Irradiation was delivered to the entire breast, for a median total dose of 50 Gy; the tumour bed was boosted in 295 cases (50% at a median dose of 10 Gy. Results After a median follow-up of 136 months (range: 16–292 months, 59/586 patients (10% experienced a local recurrence: invasive in 37 cases, intraductal in 20 and not specified in two. Salvage mastectomy was the treatment of choice in 46 recurrent patients; conservative surgery in 10 and it was unknown in three patients. The incidence of local recurrence was significantly higher in women younger than 40 years (31.3% (p= 0.0009. Five patients developed distant metastases. Furthermore 40 patients developed a contralateral breast cancer and 31 a second primary tumour in a different site. The 10-year actuarial overall survival (OS was 95.5% and the 10-year actuarial disease-specific survival (DSS was 99%. Conclusions Our results are consistent with those reported in the literature.

    Preoperative assessment of pure Ductal Carcinoma Insitu (DCIS) is essential in the surgical planning. The role of Magnetic resonance imaging (MRI) has long been debated. The impact of MRI on the management of High Grade (HG) DCIS was assessed, whether it accurately captures the true size of this entity in comparison to conventional imaging, and, if MRI use would reduce the number of re-excision surgery. Ninety-one consecutive patients with HG DCIS, who were identified from a prospectively collected data at Kettering General Hospital between April 2011 and December 2015. All patients had preoperative MRI scan in addition to the standard breast imaging. This was compared to a control group of consecutive patients (n=52) which was obtained from a period just before 2011. Impact on surgical planning and number of surgeries for each patient was compared. The size of HG DCIS estimated by MRI was compared to the final histological size. Secondary outcomes included change of initial surgical plan and detection of occult contralateral breast cancer. MRI group had 91 patients with median age of 63. Seventy percent of which presented through the screening program. The overall sensitivity of MRI to detect HG DCIS was 77% (70/91) with a false negative rate FNR of 23% (21/91). Therefore, 70 patients only were included in the data analysis. The control group included 52 screening patients with comparable baseline characteristics. Re-excision (or completion mastectomy) rates were higher in the control group 26% compared to 8% in the MRI group (P-value 0.012). MRI use correctly converted the initial plan of breast conservation to mastectomy in 9 patients (13%). Five patients had additional ipsilateral malignant features (7%).Occult contra lateral disease, was diagnosed in 2 patients (3%). This study suggests that MRI could be an important tool in reducing the re-excision rates in the surgical management of HG DCIS. Although still controversial, selective MRI imaging can be useful

    Purpose: Although the clinical outcome after treatment of ductal carcinoma in situ (DCIS) using breast-conservation surgery and radiation therapy has been well documented, little data has been reported on cosmetic outcome or treatment complications. Therefore, the present study was performed to evaluate cosmesis and complications after breast-conservation treatment for DCIS and to analyze various factors that might affect cosmesis and predispose to complications. Methods and Materials: The records of 90 patients who were alive without evidence of disease with a 3-year minimum follow-up were evaluated for cosmetic results and treatment complications following breast-conservation surgery and radiation therapy for DCIS. Complete gross excision of the primary tumor had been performed in all patients. Additionally, 24 patients had undergone an axillary lymph node dissection in the earlier years of the study. The majority of the patients had received 50-50.4 Gy to the whole breast followed by an electron boost for a total dose of 60-66 Gy. Results: The cosmetic results of 90 evaluable patients at 3 years were: excellent in 69 (77%), good in 19 (21%), and fair in 2 (2%). The cosmetic results of 64 evaluable patients at 5 years were: excellent in 46 (72%), good in 16 (25%), and fair in 2 (3%). Factors associated with worse cosmetic results were an increased volume of tissue excised (>70 cm 3 ) and a negative ipsilateral breast biopsy after radiotherapy. Complications in the 24 patients with an axillary dissection were: arm edema (n = 6), cellulitis of the arm (n = 5), and axillary vein thrombosis (n = 1). Complications in the 66 patients without an axillary dissection were: cellulitis of the arm (n = 1) and cellulitis of the breast (n = 1). Discussion: Breast-conservation surgery followed by radiation therapy achieved excellent or good cosmetic results in 98 and 97% of patients at 3 years and 5 years, respectively. Complications were associated primarily with axillary

    Purpose: To compare the clinical-pathologic features and long-term outcomes for women with ductal carcinoma in situ (DCIS) vs. DCIS with microinvasion (DCISM) treated with breast conservation therapy (BCT), to assess the impact of microinvasion. Patients and Methods: A total of 393 patients with DCIS/DCISM from our database were analyzed to assess differences in clinical-pathologic features and outcomes for the two cohorts. Results: The median follow-up was 8.94 years, and the mean age was 55.8 years for the entire group. The DCISM cohort was comprised of 72 of 393 patients (18.3%). Surgical evaluation of the axilla was performed in 58.3% (n = 42) of DCISM vs. 18.1% (n = 58) of DCIS, with only 1 of 42 DCISM (2.3%) vs. 0 of 58 DCIS with axillary metastasis. Surgical axillary evaluation was not an independent predictor of local-regional relapse (LRR), distant relapse-free survival (DRFS), or overall survival (OS) in Cox proportional hazards analysis (p > 0.05). For the DCIS vs. DCISM groups, respectively, the 10-year breast relapse-free survival was 89.0% vs. 90.7% (p = 0.36), DRFS was 98.5% vs. 97.9% (p = 0.78), and OS was 93.2% vs. 95.7% (p = 0.95). The presence of microinvasion did not correlate with LRR, age, presentation, race, family history, margin status, and use of adjuvant hormonal therapy (all p > 0.05). In univariate analysis, pathology (DCIS vs. DCISM) was not an independent predictor of LRR (hazard ratio [HR], 1.58; 95% confidence interval [CI], 0.58-4.30; p = 0.36), DRFS (HR, 0.72; 95% CI, 0.07-6.95; p = 0.77), or OS (HR, 1.03; 95% CI, 0.28-3.82; p = 0.95). Conclusions: Our data imply that the natural history of DCISM closely resembles that of DCIS, with a low incidence of local-regional and distant failures. On the basis of our large dataset, the incidence of axillary metastasis in DCISM appears to be small and not appear to correlate to outcomes, and thus, microinvasion alone should not be the sole criterion for more aggressive treatment.

    2014-01-01

    Full Text Available Introduction: This study aims to identify protein clusters with potential functional relevance in the pathogenesis of hepatocellular carcinoma (HCC and metastatic hepatic carcinoma using network analysis. Materials and Methods: We used human protein interaction data to build a protein-protein interaction network with Cytoscape and then derived functional clusters using MCODE. Combining the gene expression profiles, we calculated the functional scores for the clusters and selected statistically significant clusters. Meanwhile, Gene Ontology was used to assess the functionality of these clusters. Finally, a support vector machine was trained on the gold standard data sets. Results: The differentially expressed genes of HCC were mainly involved in metabolic and signaling processes. We acquired 13 significant modules from the gene expression profiles. The area under the curve value based on the differentially expressed modules were 98.31%, which outweighed the classification with DEGs. Conclusions: Differentially expressed modules are valuable to screen biomarkers combined with functional modules.

    NSD3 has been implicated as a candidate driver oncogene from the 8p11-p12 locus, and we have previously published evidence for its amplification and overexpression in human breast cancer. This aim of this study was to further characterize the transforming function of NSD3 in vivo. We generated a transgenic mouse model in which NSD3 gene expression was driven by the MMTV promoter and expressed in mammary epithelium of FVB mice. Mammary glands were fixed and whole mounts were stained with carmine to visualize gland structure. Mammary tumors were formalin-fixed, and paraffin embedded (FFPE) tumors were stained with hematoxylin and eosin. Pups born to transgenic females were significantly underdeveloped compared to pups born to WT females due to a lactation defect in transgenic female mice. Whole mount analysis of the mammary glands of transgenic female mice revealed a profound defect in functional differentiation of mammary gland alveoli that resulted in the lactation defect. We followed parous and virgin NSD3 transgenic and control mice to 50 weeks of age and observed that several NSD3 parous females developed mammary tumors. Whole mount analysis of the mammary glands of tumor-bearing mice revealed numerous areas of mammary hyperplasia and ductal dysplasia. Histological analysis showed that mammary tumors were high-grade ductal carcinomas, and lesions present in other mammary glands exhibited features of alveolar hyperplasia, ductal dysplasia, and carcinoma in situ. Our results are consistent with our previous studies and demonstrate that NSD3 is a transforming breast cancer oncogene.

    Full Text Available The past decade has seen a rapid proliferation in the number and types of systemic therapies available for renal cell carcinoma. However, surgery remains an integral component of the therapeutic armamentarium for advanced and metastatic kidney cancer. Cytoreductive surgery followed by adjuvant cytokine-based immunotherapy (predominantly high-dose interleukin 2 has largely given way to systemic-targeted therapies. Metastasectomy also has a role in carefully selected patients. Additionally, neoadjuvant systemic therapy may increase the feasibility of resecting the primary tumor, which may be beneficial for patients with locally advanced or metastatic disease. Several prospective trials examining the role of adjuvant therapy are underway. Lastly, the first immune checkpoint inhibitor was approved for metastatic renal cell carcinoma (mRCC in 2015, providing a new treatment mechanism and new opportunities for combining systemic therapy with surgery. This review discusses current and historical literature regarding the surgical management of patients with advanced and mRCC and explores approaches for optimizing patient selection.

    Lactic acid bacteria which are used as probiotics have ability to modulate immune responses and modify immune mechanisms. It has also been indicated that some strains of this family can affect the immune responses against solid tumors. In the present work, we proposed to study the effects of oral administration of L.cacesi ssp casei on the NK cells cytotoxicity and also production of cytokines in spleen cells culture of BALB/c mice bearing invasive ductal carcinoma. 30 female In-bred BALB/c mice, were used and divided in two groups of test and control each containing 15 mice. Every day from 2 weeks before tumor transplantation 0.5 ml of PBS containing 2.7×108 CFU/ml of L.casei spp casei was orally administered to the test mice and it was followed 3 weeks after transplantation as well with 3 days interval between each week. Control mice received an equal volume of PBS in a same manner. Results showed that oral administration of L. casei significantly increased the production of IL-12 and IFN-γ (Psurvival was significantly prolonged in comparison to the controls. Our findings suggest that daily intake of L.casei can improve immune responses in mice bearing invasive ductal carcinoma, but further studies are needed to investigate the other involving mechanisms in this case.

    Papillomaviruses (PV) are associated with benign mucosal and cutaneous epithelial proliferations. In dogs, PV-associated pigmented plaques and papillomas can undergo malignant transformation, but this is rare, and most cases of canine squamous cell carcinoma do not arise from PV-induced precursor lesions. We describe herein the progression of pigmented plaques to invasive and metastatic squamous cell carcinoma associated with 2 canine papillomaviruses (CPV) in 2 related Basenji dogs. Immunohistochemistry for PV antigen revealed strong nuclear immunoreactivity within keratinocytes from pigmented plaques from both dogs, consistent with a productive viral infection. Polymerase chain reaction (PCR) using degenerate primers for the L1 gene revealed PV DNA sequences from 2 different CPVs. In situ hybridization for CPV revealed strong hybridization signals within the pigmented plaques and neoplastic squamous epithelial cells from both dogs. We report here progression of PV-associated pigmented plaques to metastatic squamous cell carcinoma within 2 Basenji dogs associated with 2 different CPVs. © The Author(s) 2016.

    We recently reported the downregulation of osteoprotegerin expression in primary colorectal carcinoma and its significant association with aggressive oncogenic behavior, which suggest that this process contributes to colorectal carcinoma development and progression. In this study, we used immunohistochemical staining to evaluate osteoprotegerin expression in 81 colorectal liver metastasis tissue samples and investigated its possible association with the clinicopathological characteristics and outcomes of patients with colorectal liver metastasis. These tissues exhibited significantly reduced expression of osteoprotegerin compared to primary colorectal carcinomas and normal colorectal mucosa. This reduced expression was significantly associated with the extent of colorectal liver metastasis, including multiplicity of metastatic tumors, involvement of the bilateral hepatic lobes, and higher histological grade. In addition, reduced osteoprotegerin expression was an independent significant predictor of recurrent liver metastasis and prognostic factor for reduced patient survival. These findings suggest that osteoprotegerin expression may be a novel predictor of recurrent liver metastasis and a prognostic biomarker in patients with colorectal liver metastasis. Patients harboring colorectal liver metastasis with reduced osteoprotegerin expression should be carefully monitored after hepatic resection for colorectal liver metastasis to enable early detection of potentially resectable metastatic recurrences.

    Full Text Available Here we report a case of a 45-year-old female who underwent thyroidectomy for thyroid cancer and presented 20 years later with a left renal mass. CT-guided core biopsy was performed, and imprints and histologic sections of the biopsy showed cells resembling thyroid follicular cells with a background containing colloid. Immunohistochemistry revealed positivity for thyroglobulin and thyroid transcription factor 1, consistent with metastatic follicular thyroid carcinoma (FTC. The patient later underwent radical nephrectomy; histologic sections of the resected tumor revealed an encapsulated lesion morphologically similar to the biopsy specimen. Thyroid metastases to the kidney are extremely rare and are often detected during postthyroidectomy surveillance by elevation in thyroid hormone levels, 131I scintigraphy, or 18F-fluorodeoxyglucose uptake in positron emission tomography studies. Treatment involves total thyroidectomy, resection of the metastatic foci, and 131I therapy. The differential diagnoses of renal metastasis of FTC include the encapsulated follicular variant of papillary thyroid carcinoma (PTC, which possesses some of the nuclear features seen in conventional PTC but may occasionally be indistinguishable from FTC in cytologic preparations, and renal lesions such as benign thyroidization of the kidney and thyroid-like follicular carcinoma of the kidney, which mimic FTC in histologic appearance but do not stain with thyroid markers.

    Full Text Available Abstract Introduction Laparoscopic port-site metastasis is a rare but well recognized outcome following surgery in urological cancers, with its etiology not clearly understood. Additionally, vaginal metastasis in clear cell renal cell carcinoma is rare, and has not been previously reported in the setting of papillary renal cell carcinoma. Case presentation We present the case of a 71-year-old Chinese woman with metastatic type II papillary renal cell carcinoma with histologically verified vaginal involvement and a concurrent laparoscopic port-site metastasis. This was also associated with a unique constellation of widely disseminated metastatic sites, which include a local relapse, the peritoneum and the urethra. Conclusion Laparoscopic port-site metastases are associated with the presence of advanced cancer with multiple sites of metastasis. We hypothesize from the findings of our report and background data that this phenomenon is more likely to be related to tumor factors rather than operative factors. We also present what is, to the best of our knowledge, the first reported case in the literature of vaginal and urethral metastasis and the second reported case of laparoscopic port-site recurrence.

    Full Text Available Renal cell carcinoma (RCC accounts for approximately 3% of all adult malignancies. True gastrointestinal metastases, specifically to gastric wall, have been rarely observed. Herein we describe a case of delayed metastasis to gastric wall occurring more than a decade after previously curative nephrectomy for RCC. A 67-year-old male with history of right radical nephrectomy in 2001 for RCC was found to have an asymptomatic right lower lobe solitary lung mass upon routine follow-up in 2011, with final biopsy results showing metastatic RCC for which he was treated accordingly. In 2014, patient was evaluated for dyspepsia with microcytic anemia and underwent an esophagogastroduodenoscopy and colonoscopy. EGD revealed a solitary one-centimeter atypical ulcer in the posterior mid gastric body with biopsy results being consistent with metastatic RCC. Our literature review has yielded thirty-six reported cases of RCC in association with gastric wall metastases.

    The abdominal wall is a very rare site for endometrial cancer metastases. Its appearance generally indicates advanced cancer with poor prognosis. We report a case of a 55-year-old female who presented with an incisional hernia 4 years after abdominal panhysterectomy for endometrioid adenocarcinoma in 2009. Open hernia mesh repair was performed but on follow-up, she complained of pain and a swelling at the repair site. This was radiologically diagnosed as fibromatosis, but tru-cut biopsy confirmed presence of fibromatosis as well as a metastatic endometrial carcinoma. She was started on neoadjuvant chemotherapy, but had poor response, and therefore, radical excision was performed. She remained well with no metastatic recurrence at 12-month follow-up. This case illustrates late appearance of abdominal wall metastasis from abdomino-pelvic malignancies and highlights the need to exclude the presence of recurrence or metastases prior to surgical repair of incisional hernia occurring after the resection of abdominal or pelvic malignancy.

    Radiotherapy often is used for palliation of bone pain from metastatic cancer of the prostate but an objective evaluation of its efficacy in a large series of patients is unavailable. We report the results of external beam irradiation in 62 patients who had bone pain secondary to stage D carcinoma of the prostate. The variables used to judge pain before and after radiotherapy included subjective evaluation of pain, status of activity and quantitation of analgesic use. Complete relief of pain was achieved in 26 patients (42 per cent), partial relief in 22 (35 per cent) and no relief in 14 (23 per cent). On the basis of our experience external beam irradiation is useful palliative therapy for pain from metastatic cancer of the prostate

    To summarize data on long-term ipsilateral local recurrence (LR) and breast cancer death rate (BCDR) for patients with ductal carcinoma in situ (DCIS) who received different treatments. Systematic review and study-level meta-analysis of prospective (n = 5) and retrospective (n = 21) studies of patients with pure DCIS and with median or mean follow-up time of ≥10 years. Meta-regression was performed to assess and adjust for effects of potential confounders – the average age of women, period of initial treatment, and of bias – follow-up duration on recurrence- and death-rates in each treatment group. LR and BCDR rates by local treatment used were reported. Outside of randomized trials, remaining studies were likely to have tailored patient treatment according to the clinical situation. Nine thousand four hundred and four DCIS cases in 9391 patients with 10-year follow-up were included. The adjusted meta-regression LR rate for mastectomy was 2.6 % (95 % CI, 0.8–4.5); breast-conserving surgery with radiotherapy (RT), 13.6 % (95 % CI, 9.8–17.4); breast-conserving surgery without RT, 25.5 % (95 % CI, 18.1–32.9); and biopsy-only (residual predominately low-grade DCIS following inadequate excision), 27.8 % (95 % CI, 8.4–47.1). RT + tamoxifen (TAM) in conservation surgery (CS) patients resulted in lower LR compared to one or no adjuvant treatments: LR rate for CS + RT + TAM, 9.7 %; CS + RT(no TAM), 14.1 %; CS + TAM(no RT), 24.7 %; CS(alone), 25.1 % (linear trend for treatment P < 0.0001). Compared to CS + RT + TAM, a significantly higher invasive LR was observed for CS(alone), odds ratio (OR) 2.61 (P < 0.0001); CS + TAM(no RT), OR 2.52 (P = 0.001); CS + RT(no TAM), OR 1.59 (P = 0.022). BCDR was similar for mastectomy, breast-conserving surgery with or without RT (1.3–2.0 %) and non-significantly higher for biopsy-only (2.7 %). Additionally, the 15-year follow-up was reported where all like-studies had ≥ 15-year data sets; the biopsy-only patients had a

    To examine the expression of E-cadherin in paired primary and metastatic signet-ring cell carcinomas (SRCC) of various organ systems in order to explore the potential role of the molecule in metastatic dissemination of this unique tumour type. Thirty-seven consecutive cases of SRCC from various organs with paired primary and metastatic tumorous tissue available were retrieved. The intensity of membranous E-cadherin expression was semiquantitatively scored on a scale of 0-3+. Reduced E-cadherin expression was a distinct feature of primary SRCC and was observed in 78% of primary tumours. Interestingly, the E-cadherin reduction was less frequently seen in metastatic SRCC when compared with their primary counterparts, and was only found in 57% of tumours in lymph node metastases or at distant sites of relapse. Furthermore, the mean score of E-cadherin expression of primary SRCC was significantly lower than that of their metastatic counterparts (2.3 vs 1.8; p=0.008). When divided by organ systems, the reacquisition of E-cadherin expression in the metastatic deposits was most remarkable in the SRCC of upper gastrointestinal tract origin (2.3 vs 1.4; p=0.003), whereas no significant difference was observed in other organ systems. While the reduction of E-cadherin in primary SRCC supports its pivotal role in epithelial-mesenchymal transition, a process crucial in tumour progression and metastatic dissemination, the re-expression of this molecule in metastatic SRCC cells implies a reversal to their epithelial phenotype (thus mesenchymal-epithelial transition) which, in turn, theoretically helps tumour cells to anchor and form cohesive metastatic deposits.

    Full Text Available Papillary carcinoma of the thyroid with clinically significant cervical lymphadenopathy is a common presentation (particularly in young patients, and it may be the first manifestation of disease. Occasionally, besides metastatic deposits, the cervical lymph nodes may harbor other diseases, and determining the etiology in such a case becomes critical for the institution of proper treatment and complete cure of the patient. Detection of tuberculous lymphadenitis and metastatic deposits by radiological and/or fine needle aspiration cytology methods may not be always easy and may be missed due to inherent defects of the techniques hence, histopathological examination still remains the final resort. We report a case of papillary carcinoma of the thyroid and its rare association with both metastatic deposits and tuberculosis of the contiguous cervical lymph node groups. We suggest that tuberculosis must always be borne in mind besides metastases while evaluating the enlarged neck nodes in papillary carcinoma of the thyroid.

  2. Metastatic breast carcinoma uncovered in an otherwise unremarkable “random colon biopsy”

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available Breast cancer is one of the most devastating cancers afflicting women, being a main cause of cancer related death. Approximately 50% of these patients have developed regional or distant metastases at the time of diagnosis; hence, an early diagnosis and surgery with indicated neoadjuvant therapy are crucial in eradicating this disease and improving patient survival. A significant percentage of patients, even after initial satisfactory tumor removal, still face the threat of metastatic diseases which could plague a wide spectrum of body sites such as bones, lungs, central nervous system, liver and gastrointestinal tract (mostly upper gastrointestinal locations. Colonic and anorectal involvement by metastatic breast cancer has been less frequently reported in disseminated diseases. Typically, metastatic disease presents as a mass, enteric stenosis, or obstruction. Rare cases, however, may not form an endoscopically or radiologically recognizable lesion, and thus could be overlooked. Here we report a unique case of random colon biopsies in a patient presenting with epigastric pain, whose stomach biopsy showed Helicobacter pylori-associated chronic active gastritis. No colonoscopic lesion was present; however, microscopic examination of the “random biopsy” revealed scattered single and small clusters of tumor cells involving the lamina propria of the colonic mucosa, morphologically and immunophenotypically consistent with metastatic disease from breast carcinoma. The clinical presentation and histopathology of the case were reviewed and compared with limited cases reported in the literature. We conclude that high levels of suspicion and alertness are essential to identify occult microscopic gastrointestinal metastatic breast cancer in the absence of a grossly appreciable lesion.

    This case highlights the importance of recognition of the pattern of metastatic brachialplexopathy in breast cancer patients undergoing {sup 18}F-fluorodeoxyglucose ({sup 18}F-FDG) positron emission tomography/computed tomography (PET/CT) for evaluation of recurrent disease.This pattern can be appreciated on maximum intensity projection (MIP) and coronal {sup 18}F-FDG PET/CT images as a linear extension of tracer activity from superomedial aspect(supra/infraclavicular) to lateral aspect of the axilla closely related to the subclavian/axillary vessels). A 35-year-old woman diagnosed with infiltrating ductal carcinoma of the right breast had undergone six cycles of neoadjuvant chemotherapy, followed by wide local incision and radiotherapy. She had local recurrence, for which she was operated upon and given chemotherapy. She presented to her oncologist with pain and swelling in the right breast, nodules in the right axilla and restriction of movement of the right upper limb. The patient was referred for {sup 18}F-FDG PET/CT to evaluate the extent of recurrent/metastatic disease. Whole-body PET/CT was acquired 1 h following the intravenous injection of 296 MBq of {sup 18}F-FDG on a Biograph mCT scanner (Siemens). Evaluation of the MIP image revealed abnormal FDG accumulation at multiple sites in the thorax, along with a linear pattern of FDG uptake in the right lateral aspect of the upper chest (Fig. 1a, arrow). The coronal fused PET/CT image revealed a linear pattern of FDG uptake corresponding to an ill-defined mass extending from just behind the right clavicle into the right axilla (arrow). In addition, abnormal FDG accumulation was seen in a soft tissue density mass in the upper outer quadrant of the right breast, skin of the right breast laterally, both pectoral muscles (discrete foci) and in a few subpectoral nodes. Soft tissue nodular opacities in both lungs showed FDG accumulation suggestive of pulmonary metastasis (Fig. 1b, thick arrow). The patient was

    Full Text Available We report here on a case of 51-year-old woman with metastatic small cell carcinoma of the breast that came from her cancer of the uterine cervix. She underwent radical hysterectomy with bilateral salpingo-oophorectomy due to small cell carcinoma of the uterine cervix, and adjuvant radiotherapy was administered to the pelvis. Breast metastasis with a palpable mass then occurred 3 months after the primary surgery. Simple mastectomy and adjuvant chemotherapy were performed. She initially showed a good response to the therapy, yet she ultimately died of multiple metastases with a fulminating disease course. This is an extremely rare case, and only 1 similar case has been reported earlier, so we report on this case along with a review of the relevant literature.

    Full Text Available Differentiating between clear cell neuroendocrine tumor (NET of the pancreas and renal cell carcinoma (RCC metastatic to the pancreas can be challenging in patients with von Hippel-Lindau disease (VHL. The clear cell features of both NET and RCC in VHL patients may lead to misdiagnosis, inaccurate staging, and alternative treatment. We present a patient in which this occurred. As clear cell NETs closely resembling metastatic RCC are distinctive neoplasms of VHL and metastatic RCC to the pancreas in the VHL population is rare, careful pathologic examination should be performed prior to subjecting patients to definitive surgical or medical therapies.

Articles of interest analyze the efficacy of radiotherapy for treatment of metastatic MCC and did not exclude case reports. Results. All articles except one focusing on the role of radiotherapy were of retrospective origin or case series. Significant limitations applied in all studies due to limited sample sizes and the retrospective nature of these studies. Radiotherapy improves locoregional control in the adjuvant setting, and many series suggest an improvement in overall survival. In cases where surgery is not possible, definitive radiotherapy may be an as-efficacious alternative. The radiosensitive nature of MCC coupled with existing reports suggests that treatment via current protocols for other primary tumors is adequate. Conclusion.

    An improved understanding of renal cell carcinoma (RCC) biology has translated into major advances in the treatment of patients with metastatic RCC in recent years. Clinical and pathologic criteria can be used to identify RCC patients with poor prognoses. Such patients, however, are often excluded from the cancer clinical trials that guide treatment recommendations. This article reviews available information on the management of patients with metastatic RCC and poor risk features, focusing on the role of vascular endothelial growth factor (VEGF) pathway and mammalian target of rapamycin (mTOR) inhibitors. While patients with poor risk features have a more guarded outcome, treatment with temsirolimus has produced meaningful improvements in overall survival for this population. Definitive phase III trial data are lacking for the VEGF pathway inhibitors in patients with poor prognostic features. However, available data suggest that such patients tolerate VEGF pathway blockade reasonably well and are likely to achieve some benefit relative to treatment with interferon. Ongoing translational research efforts may help to define novel treatment approaches specific for patients with metastatic RCC and poor prognostic features

    Full Text Available Introduction. Merkel cell carcinoma is a rare form of non-melanoma skin cancer of neuroendocrine origin. Optimal management of patients is controversial and the role of radiotherapy is unclear. Purpose. The purpose of this study was to review the efficacy of RT in the treatment of both local and distant metastatic disease from MCC. Methods.

    15±30% of malignancies detected through screening programs are ductal carcinoma in situ (DCIS), and the majority of DCIS cases present in the form of mammographic microcalcification. This study was performed in order to determine the value of features in predicting invasive disease in patients with mammographic calcification and to help determine which patients (with, Core Needle Biopsy-diagnosed DCIS) are the most appropriate candidates for Sentinel Lymph Node (SLN) biopsy. The original aspect of this study was to select patients with mammographic microcalcification but without an associated mass. The factor that we identified to be associated with invasive disease at final surgical excision was the presence of necrosis at core histology. SLN biopsy or complete axillary lymph node dissection was performed in 22 (40%) patients of whom only one (4.5%) had a micrometastasis. Further larger studies are needed to see if it would be interesting to propose a SLN biopsy in case of necrosis on CNB-diagnosed DCIS with microcalcifications but not associated with a mass.

    Full Text Available Background. Sarcomatoid squamous cell carcinoma is a rare and aggressive form of cervical cancer. We report a case of metastatic sarcomatoid squamous cell carcinoma (SSCC of cervix that presented with an anterior chest wall mass. Case. A 43-year-old Hispanic female presented with a two-month history of a central chest wall mass. The patient’s only past medical history was SSCC of the cervix, stage IIB, diagnosed two years priorly. She underwent neoadjuvant chemoradiation therapy (CRT with cisplatin followed by radical hysterectomy. Surgical margins were positive which led to adjuvant CRT with carboplatin and paclitaxel. PET scan 4 months after the postoperative treatment was negative for recurrence and metastatic disease. On current presentation, the CT chest revealed anterior mediastinal destructive soft tissue mass involving sternum, and the biopsy showed SSCC. The patient received palliative radiation therapy to her chest with improvement in pain and ability to swallow. After discussing the prognosis she refused further chemotherapy and decided on hospice care. Conclusion. Despite good response to first-line therapy, SSCC tends to recur early and does not respond to second-line therapy. Radiation therapy seems to be the most effective modality for treatment, but randomized controlled trials of therapy are impractical.

    MINI: A 3D printing technology is proposed for reconstructing multilevel cervical spine (C2-C4) after resection of metastatic papillary thyroid carcinoma. The personalized porous implant printed in Ti6AL4V provided excellent physicochemical properties and biological performance, including biocompatibility, osteogenic activity, and bone ingrowth effect. A unique case report. A three-dimensional (3D) printing technology is proposed for reconstructing multilevel cervical spine (C2-C4) after resection of metastatic papillary thyroid carcinoma in a middle-age female patient. Papillary thyroid carcinoma is a malignant neoplasm with a relatively favorable prognosis. A metastatic lesion in multilevel cervical spine (C2-C4) destroys neurological functions and causes local instability. Radical excision of the metastasis and reconstruction of the cervical vertebrae sequence conforms with therapeutic principles, whereas the special-shaped multilevel upper-cervical spine requires personalized implants. 3D printing is an additive manufacturing technology that produces personalized products by accurately layering material under digital model control via a computer. Reporting of this recent technology for reconstructing multilevel cervical spine (C2-C4) is rare in the literature. Anterior-posterior surgery was performed in one stage. Radical resection of the metastatic lesion (C2-C4) and thyroid gland, along with insertion of a personalized implant manufactured by 3D printing technology, were performed to rebuild the cervical spine sequences. The porous implant was printed in Ti6AL4V with perfect physicochemical properties and biological performance, such as biocompatibility and osteogenic activity. Finally, lateral mass screw fixation was performed via a posterior approach. Patient neurological function gradually improved after the surgery. The patient received 11/17 on the Japanese Orthopedic Association scale and ambulated with a personalized skull-neck-thorax orthosis on

    Clear cell renal cell carcinomas (CCRCC) rarely metastasizes to the gynecologic tract. In this study, we analyzed a multi-institutional data set to provide insights into the clinical, morphologic, and immunophenotypic features of this phenomenon. Seveteen metastatic CCRCC involving the gynecologic tract [ovary/fallopian tube (n=9), vulva (n=2), uterine corpus (n=3), cervix (n=2), uterine serosa (n=1)] were analyzed. Mean patient age was 62 yr (range: 45-79 yr). Most cases (15/17) presented as a recurrence 6 to 72 mo postnephrectomy, 1 case was concurrently diagnosed, and 1 case (a cervical metastasis) was diagnosed prenephrectomy. In 10 cases, metastases to other locations were identified within 6 wk of the gynecologic tract lesion. The adnexa were the most common site of metastases and the mean tumor size of adnexal metastases was 3.7 cm; in only 2 of 9 cases were metastases bilateral and only 1 had external surface nodules. The morphologic and immunohistochemical features of metastatic CCRCC were compared with those of 102 müllerian clear cell carcinomas (müllerian CCC: 49 endometrial, 53 ovarian). Although CCRCC and müllerian CCC displayed extensive morphologic overlap, a higher mitotic index and a higher frequency of an alveolar pattern were seen in CCRCC, whereas diffuse hobnail cells, hyaline globules, tubulocystic pattern, or any papillary pattern were more frequently seen in müllerian CCC. CA-IX, CD10, and renal cell carcinoma antigen were more frequently expressed in CCRCC than müllerian CCC, whereas Napsin-A, CK7, and p504S showed the reverse. PAX8 and HNF1β did not significantly distinguish between the 2 groups. In summary, gynecologic tract metastases most often occur as a relapse of a previously resected CCRCC, and these relapses may occur many years postnephrectomy. Gynecologic tract metastases are often accompanied by concurrent metastases to other organs. The gross pathology of metastatic CCRCC in the ovary may potentially overlap

    Purpose: To determine 20-year rates of local control and outcome-associated factors for ductal carcinoma in situ (DCIS) after breast-conserving therapy (BCT). Methods and Materials: All DCIS cases receiving BCT between 1980 and 1993 were reviewed. Patient demographics and pathologic factors were analyzed for effect on outcomes, including ipsilateral breast tumor recurrence (IBTR) and survival. Results: One hundred forty-five cases were evaluated; the median follow-up time was 19.3 years. IBTR developed in 25 patients, for 5-, 10-, 15-, and 20-year actuarial rates of 9.9%, 12.2%, 13.7%, and 17.5%, respectively. One third of IBTRs were elsewhere failures, and 68% of IBTRs occurred <10 years after diagnosis. Young age and cancerization of lobules predicted for IBTR at <10 years, and increased slide involvement and atypical ductal hyperplasia were associated with IBTR at later time points. Conclusions: Patients with DCIS treated with BCT have excellent long-term rates of local control. Predictors of IBTR vary over time, and the risk of recurrence seems highest within 10 to 12 years after diagnosis.

    Full Text Available We developed a novel inflammation-based model (NPS, which consisted of a neutrophil to lymphocyte ratio (NLR and platelet count (PC, for assessing the prognostic role in patients with metastatic urothelial carcinoma (UC.We performed a retrospective analysis of patients with metastatic UC who underwent systemic chemotherapy between January 1997 and December 2014 in Kaohsiung Chang Gung Memorial Hospital. The defined cutoff values for the NLR and PC were 3.0 and 400 × 103/μL, respectively. Patients were scored 1 for either an elevated NLR or PC, and 0 otherwise. The NPS was calculated by summing the scores, ranging from 0 to 2. The primary endpoint was overall survival (OS by using Kaplan-Meier analysis. Multivariate Cox regression analysis was used to identify the independent prognostic factors for OS.In total, 256 metastatic UC patients were enrolled. Univariate analysis revealed that patients with either a high NLR or PC had a significantly shorter survival rate compared with those with a low NLR (P = .001 or PC (P < .0001. The median OS in patients with NPS 0, 1, and 2 was 19.0, 12.8, and 9.3 months, respectively (P < .0001. Multivariate analysis revealed that NPS, along with the histologic variant, liver metastasis, age, and white cell count, was an independent factor facilitating OS prediction (hazard ratio 1.64, 95% confidence interval 1.20-2.24, P = .002.The NLR and PC are independent prognostic factors for OS in patients with metastatic UC. The NPS model has excellent discriminant ability for OS.

    Full Text Available Metastatic spread of breast carcinoma to the colon and rectum is rare. We report the case of a patient treated for lobular breast carcinoma presenting 17 years later with metastatic breast cancer of the colon. A 63-year-old lady with a past history of right-sided invasive lobular carcinoma of the breast presented with persistent diarrhoea. Colonoscopy with biopsies revealed a benign-looking stricture at the rectosigmoid junction. A CT scan of the abdomen and pelvis revealed a benign-looking stricture in keeping with a probable diverticular stricture. A Hartmann procedure was performed and histology revealed a metastatic lobular carcinoma with oestrogen and progesterone receptor-positive status. Treatment was commenced with letrozole and the patient remains well under clinical surveillance. In a patient with a history of breast carcinoma who presents with gastrointestinal symptoms the possibility of gastrointestinal tract spread should always be considered. Endoscopic diagnosis may be misleading with pathological diagnosis only being made following surgical resection. A history of breast carcinoma must be declared to the histopathologist following surgical resection so that an accurate diagnosis is made and appropriate treatment is commenced.

    Full Text Available Abstract Background Breast cancer is the most common cancer and the leading cause of cancer mortality in women worldwide. Hypoxia is an important factor involved in the progression of solid tumors and has been associated with various indicators of tumor metabolism, angiogenesis and metastasis. But little is known about the contribution of Hypoxia-Inducible Factor-2a (HIF-2a to the drug resistance and the clinicopathological characteristics in breast cancer. Methods Immunohistochemistry was employed on the tissue microarray paraffin sections of surgically removed samples from 196 invasive breast cancer patients with clinicopathological data. The correlations between the expression of HIF-2a and ABCG2 as well as other patients' clinicopathological data were investigated. Results The results showed that HIF-2a was expressed in different intensities and distributions in the tumor cells of the breast invasive ductal carcinoma. A positive staining for HIF-2a was defined as a brown staining observed mainly in the nucleus. A statistically significant correlation was demonstrated between HIF-2a expression and ABCG2 expression (p = 0.001, histology-grade (p = 0.029, and Ki67 (p = 0. 043 respectively. Conclusion HIF-2a was correlated with ABCG2 expression, histology-grade and Ki67 expression in breast invasive ductal carcinoma. HIF-2a could regulate ABCG2 in breast cancer cells, and could be a novel potential bio-marker to predict chemotherapy effectiveness. The hypoxia/HIF-2a/ABCG2 pathway could be a new mechanism of breast cancer multidrug-resistance. Virtual slides http://www.diagnosticpathology.diagnomx.eu/vs/2965948166714795

    There are many cells with various phenotypic behaviors in cancer interacting with each other. For example, an apoptotic cell may induce apoptosis in adjacent cells. A living cell can also protect cells from undergoing apoptosis and necrosis. These survival and death signals are propagated through interaction pathways between adjacent cells called gap junctions. The function of these signals depends on the cellular context of the cell receiving them. For instance, a receiver cell experiencing a low level of oxygen may interpret a received survival signal as an apoptosis signal. In this study, we examine the effect of these signals on tumor growth. We make an evolutionary game theory component in order to model the signal propagation through gap junctions. The game payoffs are defined as a function of cellular context. Then, the game theory component is integrated into an agent-based model of tumor growth. After that, the integrated model is applied to ductal carcinoma in situ, a type of early stage breast cancer. Different scenarios are explored to observe the impact of the gap junction communication and parameters of the game theory component on cancer progression. We compare these scenarios by using the Wilcoxon signed-rank test. The Wilcoxon signed-rank test succeeds in proving a significant difference between the tumor growth of the model before and after considering the gap junction communication. The Wilcoxon signed-rank test also proves that the tumor growth significantly depends on the oxygen threshold of turning survival signals into apoptosis. In this study, the gap junction communication is modeled by using evolutionary game theory to illustrate its role at early stage cancers such as ductal carcinoma in situ. This work indicates that the gap junction communication and the oxygen threshold of turning survival signals into apoptosis can notably affect cancer progression.

    To evaluate whether magnetic resonance (MR) imaging features can predict the presence of occult invasion in cases of biopsy-proven pure ductal carcinoma in situ (DCIS). We retrospectively reviewed 92 biopsy-proven pure DCIS in 92 women who underwent MR imaging. The following MR imaging findings were compared between confirmed DCIS and invasive breast cancer (IBC): lesion size, type, morphological and kinetic assessments by ACR BI-RADS MRI, and findings of fat-suppressed T2-weighted (FS-T2W) imaging. Sixty-eight of 92 (74%) were non-mass-like enhancements (NMLE) and 24 were mass lesions on MR imaging. Twenty-one of 68 (31%) NMLE and 13 of 24 (54%) mass lesions were confirmed as IBC. In NMLE lesions, large lesions (P = 0.007) and higher signal intensities (SI) on FS-T2W images (P = 0.032) were significantly associated with IBC. Lesion size remained a significant independent predictor of invasion in multivariate analysis (P = 0.032), and combined with FS-T2W SIs showed slightly higher observer performances (area under the curve, AUC, 0.71) than lesion size alone (AUC 0.68). There were no useful findings that enabled the differentiation of mass-type lesions. Breast MR imaging is potentially useful to predict the presence of occult invasion in biopsy-proven DCIS with NMLE. MR mammography permits more precise lesion assessment including ductal carcinoma in situ A correct diagnosis of occult invasion before treatment is important for clinicians This study showed the potential of MR mammography to diagnose occult invasion Treatment and/or aggressive biopsy can be given with greater confidence MR mammography can lead to more appropriate management of patients.

    This study seeks to determine the relationships between manifestation of myofibroblasts in the stroma tissue of hyperplastic pre-invasive breast lesions to invasive cancer by investigating clinicopathological data of patients, their effect on steroid receptor expression and HER2, and angiogenesis according to CD34 antigen expression. 100 cases of invasive ductal carcinoma were immunohistochemically investigated for the presence of smooth muscle actin (SMA), ER/PR, HER2, anti-CD34 antibody and microvessel count (MVC). Patients were scored in four different zones of invasive areas: invasive cancer, DCIS, fibrocystic disease ± ductal intraepithelial neoplasia (FCD ± DIN), and normal tissue.  There was a significant difference in stromal myofibroblasts between all areas except for the stroma of DCIS and FCD ± DIN (P normal areas (P = 0.054). There was a significant difference in MVC observed in all areas except for DCIS and FCD ± DIN (P < 0.001). We noted significant inverse correlations between MVC, HER2 expression, and the numbers of involved lymph nodes in invasive cancer and DCIS (P < 0.001). Most MVC were present in grade I, with the least frequent observed in grade III cases in the stroma of invasive cancer, DCIS and FCD ± DIN (P < 0.001).  Angiogenesis can be observed before any significant myofibroblastic changes in the pre-invasive breast lesions. The elevated content of myofibroblasts in stroma of tumor; probably may be a worse prognostic factor  and the steps from atypical epithelial hyperplasia to DCIS and then to the invasive carcinoma do not appear to be always part of a linear progression.

    Objective was to compare initial metastatic breast carcinoma (MBC) with recurrent MBC and assess their biologic phenotypes and clinical behaviors. A comparison of clinical and biological characteristics and median overall survival times were assessed in the 251 patients with MBC at the Division of Medical Oncology, Ege University School of Medicine and the Division of radiation Oncology, Tepecik Government Hospital, Izmir, Turkey between 1995 and 2004. Hormone receptors, c-erb B-2,ki-67 and p53 expressions were performed by immunohistochemistry. Out of 251 MBC patients, 206 patients had recurrent MBC and 45 had initial MBC. Regarding survival there was no difference between the recurrent MBC group and the initial MBC group. The initial MBC group had a higher proportion of T4 tumors (46% versus 27%), a lower proportion of T-1-2 tumors (31% versus 55%; p=0.01), and higher percentage of patients with high Ki-67 expression (64% versus 49%; p=0.05). Multivariate analysis showed that T stage was an independent prognostic factor (p=0.02). Patients with initial MBC tended to present with larger tumors. This relationship can be explained by delayed diagnosis. The potential for reducing death rates from breast cancer is contingent on educational improvement and increased screening rates. (author)

    Metastatic papillary thyroid carcinoma (PTC) without an identifiable primary tumor despite extensive microscopic examination of the thyroid gland is a rare but true phenomenon.We retrieved 7 of such cases and described in detail the clinical and pathologic features of these tumors. BRAF V600E immunohistochemistry and Sequenom molecular profile were conducted in selected cases. All patients harbored metastatic disease in the central (n=3), lateral (n=3), or both neck compartments (n=1). The histotype of the metastatic disease was PTC (n=5), poorly differentiated thyroid carcinoma in association with a PTC columnar variant (n=1), and anaplastic thyroid carcinoma in association with a PTC tall cell variant (n=1). Fibrosis was present in the thyroid of 5 patients. All patients with PTC were alive without evidence of recurrence. The 76-year-old patient with poorly differentiated thyroid carcinoma did not recur and died of unknown causes. Finally, the patient with anaplastic thyroid carcinoma was alive with distant metastasis at last follow-up. The median follow-up for this cohort was 2.2years (range, 0.8-17). BRAF V600E was detected in 4 of 6 cases by immunohistochemistry. In conclusion, metastatic nodal disease without identifiable thyroid primary is a rare but real phenomenon of unknown mechanisms. Although most tumors are low grade and well differentiated, aggressive behavior due to poorly differentiated or anaplastic carcinoma can happen. Most cases are BRAF V600E -positive thyroid tumors. A papillary carcinoma phenotype is found in all reported cases. Copyright © 2017 Elsevier Inc. All rights reserved.

    Few data exist on the occurrence of metastatic basal cell carcinoma (mBCC). To identify all cases of mBCC in Denmark over a 14-year period. We searched the Danish National Patient Registry covering all Danish hospitals, the Danish Cancer Registry, the National Pathology Registry and the Causes of Death Registry during the period 1997 to 2010 for potential cases of mBCC registered according to the International classification of diseases ICD-10 and the International Systemized Nomenclature of Medicine (SNOMED). We identified 126,627 patients with a history of primary basal cell carcinoma (BCC) in the registries during the 14-year study period. Using case identifications from the four registries, a total of 170 potential mBCC cases were identified. However, after a pathology review, only five cases could be confirmed, of which three were basosquamous carcinomas. The 14-year cumulative incidence proportion of mBCC was 0.0039% (95% CI 0.0016-0.0083) among individuals with a history of previous BCC (n = 126,627) and 0.0001% (95% CI 0.0000-0.0002) in the general population. MBCC is a rare disease and only a small proportion of potential cases identified in automated clinical databases or registries can be confirmed by pathology and medical record review.

    The role of the integrin alpha 6 beta 1 in breast carcinoma progression was studied by targeted elimination of this integrin in MDA-MB-435 cells, a human breast carcinoma cell line that is highly metastatic in athymic mice. The strategy used is based on the finding that expression of a cytoplasmi...... in the liver after intrahepatic injection because of extensive apoptosis in the beta 4-delta CYT transfectants. These data suggest that a major function of the alpha 6 beta 1 integrin in breast carcinoma is to facilitate tumorigenesis and promote tumor cell survival in distant organs....

  11. p53 and erbB-2 Are Not Associated in Matched Cases of Primary and Metastatic Ovarian Carcinomas

    Full Text Available Ovarian cancer has a high mortality rate largely due to the limited number of ovarian carcinomas detected at an early stage. Understanding the molecular changes occurring during the progression of ovarian carcinoma would aid in the development of therapies that may inhibit or target metastasis. Primary and metastatic lesions from 54 and 40 patients with advanced ovarian carcinoma, respectively (including matched primary and metastatic lesions from 30 patients were evaluated for nuclear accumulation of p53 (clone BP53-12-1 and cytoplasmic and membranous immunostaining of p185 erbB-2 (clone 3B5 by immunohistochemistry. No differences in the immunostaining of p53 and p185erbB-2 (cytoplasm or membrane were observed between primary and metastatic lesions of the matched cases. Similarly, no differences in the proportion of positive cases of p53 between primary and metastatic lesions of the matched cases was observed. Thus, novel therapies that target p53 or p185erbB-2 can utilize specimens from either primary or metastatic lesions to characterize these targets prior to therapy. Spearman correlations between p53 and p185erbB-2 (cytoplasm or membrane immunohistochemistry scores were insignificant for the matched cases, all primary lesions, and all metastatic lesions. Also, no significant associations occurred between nuclear accumulation of p53 (positive versus negative and phenotypic expression of p185erbB-2 (cytoplasm or membrane immunostaining scores for the matched cases, all primary lesions, and all metastatic lesions. Thus, the nuclear accumulation of p53 and immunostaining of p185erbB-2 in the cytoplasm or on the cellular membranes are independent.

    Full Text Available Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA biopsy sampling of enlarged lymph nodes is increasingly used to diagnose metastatic tumors, especially of the gastrointestinal tract and the lungs. Herein, we describe the diagnosis of metastatic renal cell carcinoma from a native kidney of a 54 year-old male patient, who had a 5-years history of renal transplant, by EUS-FNA of mediastinal and celiac lymph nodes. Histological and immunohistochemical findings confirmed the origin of metastatic tumor. EUS-FNA with proper cytological evaluation can be useful in the diagnosis of metastatic renal cell carcinoma in renal transplant patients.

    Patients with metastatic renal cell carcinoma have a reported 5-year survival of 0% to 20%. The ability to predict which patients would benefit from nephrectomy and interleukin-2 (IL-2) therapy before any treatment is initiated would be useful for maximizing the advantage of therapy and improving the quality of life. A retrospective analysis of the x-rays and charts of patients treated at the National Institutes of Health Surgery Branch between 1985 and 1996, who presented with metastatic renal cancer beyond the locoregional area and the primary tumor in place, was performed. Preoperative computerized tomography or magnetic resonance imaging, or radiological reports if no scans were available, were used to obtain an estimate of the volume of retroperitoneal lymphadenopathy. Operative notes were used to evaluate whether all lymphadenopathy was resected or disease left in situ, or if any extrarenal resection, including venacavotomy, was performed. Mean survival rate was calculated from the time of nephrectomy to the time of death or last clinical followup. If patients received IL-2 therapy, the response to treatment was recorded. Mean survival and response rate for IL-2 were compared among patients in 3 separate analyses. Patients without preoperatively detected lymphadenopathy were compared with those with at least 1 cm.3 retroperitoneal lymphadenopathy. Also, the patients who had detectable lymphadenopathy were divided into subgroups consisting of all resected, incompletely resected, unresectable and unknown if all disease was resected. Each subgroup was compared with patients without detectable preoperative lymphadenopathy. Patients with less than were compared to those with greater than 50 cm.3 retroperitoneal lymphadenopathy. Patients undergoing extrarenal resection at nephrectomy (complex surgery) due to direct invasion of the tumor into another intra-abdominal organ were compared with those undergoing radical nephrectomy alone, regardless of lymph node status

  14. Metastatic Renal Cell Carcinoma: The Importance of Immunohistochemistry in Differential Diagnosis

    Full Text Available Introduction: Clear cell carcinoma accounts for 75% of all types of renal neoplasms. Approximately one third presents with metastatic disease at diagnosis. Immunohistochemical studies play a significant diagnostic role. Case Report: We report the case of a 48-year-old heavy smoker who presented with productive cough and progressive dyspnea. The study revealed a renal mass and lung alterations compatible with primary tumor of the lung. The patient underwent a right complete nephrectomy. The anatomopathological exam showed clear cell renal carcinoma (pT1bN0Mx. After transthoracic needle aspiration biopsy, the clinical diagnosis was stage IV adenocarcinoma of the lung. Initially, the patient received one cycle of chemotherapy (cisplatin/pemetrexed. Two weeks later, the immunohistochemistry tests revealed a secondary lesion with probable renal origin. Chemotherapy was stopped and the patient was started on sunitinib treatment. After two cycles the disease progressed. A second-line treatment with everolimus was proposed; however, the patient died 2 weeks later due to terminal respiratory insufficiency. Discussion: Clear cell renal cell carcinoma remains one of the great mimickers in pathology. Immunohistochemistry is a valuable tool in the differential diagnosis of lung carcinomas. With the help of thyroid transcription factor 1, it is possible to distinguish a primary lung tumor from a metastasis with a reasonable degree of certainty. The present case report illustrates the challenge of making a definitive and adequate diagnosis. The immunohistochemistry added information that changed the whole treatment strategy. For the best treatment approach, it is fundamental that clinicians await all possible test results, before establishing a treatment plan.

    The objective of this study was to investigate the expression and clinical role of 14 genes previously shown to be associated with chemotherapy response and/or progression-free survival in a smaller series of ovarian serous carcinoma effusions. Advanced-stage serous ovarian carcinoma effusions (n = 150) were analyzed for mRNA expression of AKR1C1, ABCA4, ABCA13, ABCB10, BIRC6, CASP9, CIAPIN1, FAS, MGMT, MUTYH, POLH, SRC, TBRKB and XPA using quantitative real-time PCR. mRNA expression was studied for association with clinicopathologic parameters, including chemotherapy response and survival. ABCA4 mRNA expression was significantly related to better (complete) chemotherapy response at diagnosis in the entire cohort (p = 0.018), whereas higher POLH mRNA levels were significantly related to better chemoresponse at diagnosis in analysis to 58 patients with pre-chemotherapy effusions treated with standard chemotherapy (carboplatin + paclitaxel; p = 0.023). In univariate survival analysis for patients with pre-chemotherapy effusions (n = 77), CIAPIN1 mRNA expression was significantly related to shorter overall (p = 0.007) and progression-free (p = 0.038) survival, whereas ABCA13 mRNA expression was significantly related to shorter OS (p = 0.024). Higher CIAPIN1 mRNA expression was an independent marker of poor overall survival in Cox multivariate analysis (p = 0.044). Our data identify ABCA4 and POLH as markers of better chemotherapy response in metastatic serous carcinoma. CIAPIN1 and ABCA13 may be novel markers of poor outcome in pre-chemotherapy serous carcinoma effusions.

    Cytoreductive nephrectomy (CN) is a therapeutic consideration in patients with metastatic renal cell carcinoma (mRCC). We hypothesized that sarcopenia, a novel marker of nutritional status, is a predictor of survival after CN. Of 105 patients who underwent CN at our institution for mRCC, 93 had preoperative imaging available for analysis. Skeletal muscle index was calculated on axial images at the third lumbar vertebrae, and a threshold skeletal muscle index of25 kg/m(2), and2 (hazard ratio = 2.09, 95% CI: 1.24-3.53; P = 0.006). Sarcopenia can be an important prognostic factor associated with worse OS after CN for mRCC. Copyright © 2015 Elsevier Inc. All rights reserved.

  17. Sudden hemorrhage in metastatic thyroid carcinoma of the brain during treatment with 131I

    1976-01-01

    A patient with papillary--follicular carcinoma of the thyroid, with metastases to the lungs, skeleton, and brain, was treated 5 weeks after thyroidectomy with 135 mCi of 131 I. Although preliminary studies with 1 mCi had not shown any iodine uptake by the brain metastasis, this lesion showed intense concentration at the time of the larger therapeutic dose. Four days later, acute hemorrhage of the tumor occurred, requiring surgical removal. Although 131 I therapy would seem an unlikely cause of acute necrosis and hemorrhage in these lesions, the association of therapeutic radioiodine and hemorrhage is interesting. Since recent reports suggest that brain metastasis may be somewhat more common than previously suspected, we suggest that brain imaging be included in the workup prior to radioiodine therapy of patients with advanced metastatic disease or neurologic symptoms

    We present an unusual case of metastatic renal cell carcinoma (RCC) mimicking diverticulitis in a 76-year-old man with a 16-year history of chronic lymphocytic leukaemia (CLL) and a 2 cm left renal mass. The patient presented with severe abdominal pain and lower gastrointestinal bleeding with anticoagulation from recent pulmonary embolism. His clinical course was troubled by recurrent hospitalisations and complications that delayed investigations and potential treatments. Radiographic findings revealed stable CLL, mild sigmoid diverticulitis and a small renal mass. Small renal masses (less than 4 cm) are considered low risk for metastasising and are, thus, often observed or ablated, rather than resected. Furthermore, gastrointestinal metastases from RCC are rare. This case adds new perspective to the unpredictable nature of RCC and how synchronous malignancies may be masked in patients with long-standing CLL. 2015 BMJ Publishing Group Ltd.

    The present thesis consists of 8 published articles focusing on interleukin-2 based immunotherapy in metastatic renal cell carcinoma (mRCC). This disease represents a significant challenge, as the tumor is resistant to current chemotherapy, hormonal therapy and radiation therapy. However, IL-2...... based immunotherapy may induce dramatic durable tumor regression by manipulating the immune system, however, only in a minority of patients. Two critical questions have driven the present thesis. First, which properties of the immune system are responsible for the dramatic tumor regression seen in some...... patients with mRCC following IL-2 administration? And second, can histamine increase the efficacy of IL-2 based immunotherapy by ending the immune suppression induced by phagocyte-generation of reactive oxygen species? 120 Danish patients, 41 UK patients and 20 Swedish patients were treated with low...

    The hedgehog (Hh) signaling pathway has been identified as important to normal embryonic development in living organisms and it is implicated in processes including cell proliferation, differentiation and tissue patterning. Aberrant Hh pathway has been involved in the pathogenesis and chemotherapy resistance of different solid and hematologic malignancies. Basal cell carcinoma (BCC) and medulloblastoma are two well-recognized cancers with mutations in components of the Hh pathway. Vismodegib has recently approved as the first inhibitor of one of the components of the Hh pathway (smoothened). This review attempts to provide current data on the molecular pathways involved in the development of BCC and the therapeutic options available for the treatment of locally advanced and metastatic BCC, and the new targeted therapies in development.

    Salivary duct carcinoma (SDC) is an aggressive form of salivary gland tumor, and SDC patients tend to be older men, more commonly in advanced stage with a poorer prognosis. Although the cytological characteristics of SDC on fine-needle aspiration cytology have been well-described at the primary site, they have not been explored in metastasis. Here we reported a case of HER2/HER3-positive metastatic SDC in the lung and pleural effusion. The patient was a man in his 50s who had undergone extended total parotidectomy in 2008. He was originally diagnosed as having HER2-positive left parotid SDC. Six years later a mass was discovered in the left lung by chest computed tomography (CT) and was diagnosed as metastatic SDC by both bronchial biopsy and cytology. Subsequently he had a recurrent SDC in the left pleural effusion and died of respiratory failure. Cytological findings from bronchial brushing smear showed small sheet clusters in a slightly necrotic background. In the pleural effusion cytology, tumor cells appeared as ball-like clusters of epithelioid cells with apocrine-like findings. In immunocytochemistry, HER3 of SDC cells in pleural effusion was significantly overexpressed relative to the matched primary tumor, even though HER2 amplification did not change. Cytological findings and HER family receptors differed between the primary and metastatic SDC. Therefore, molecular tests, such as protein expression and gene amplification using cytological specimens, may become important in future when determining therapy strategies in patients with distant metastasis. © 2017 Wiley Periodicals, Inc.

    To evaluate safety and efficacy of transarterial hepatic radioembolization treatment of patients with liver-dominant metastatic renal cell carcinoma (RCC). From July 2010 to December 2014, 18 patients with liver-dominant metastatic RCC were treated with yttrium-90 glass microsphere radioembolization. Retrospective review of medical records and imaging studies was performed to evaluate toxicities, treatment response, and overall survival. The median follow-up period from radioembolization treatment was 17.8 months (range, 3-54.4 months). Median overall survival from RCC diagnosis was 64 months (95% confidence interval [CI], 0-144.1 months), from diagnosis of liver metastasis was 29 months (95% CI, 7.2-50.8 months), and from radioembolization treatment was 22.8 months (95% CI, 13.2-32.3 months). After treatment, 10 patients reported grade 1 clinical toxicities, and 8 patients had grade 1 or 2 biochemical toxicities. The best radiographic responses of 17 patients who underwent contrast-enhanced cross-sectional imaging showed complete response in 16 patients and partial response in 1 patient evaluated by modified Response Evaluation Criteria in Solid Tumors (mRECIST) criteria. The last available imaging of these 17 patients demonstrated complete response in 14 patients, partial response in 1 patient, and progression of disease in 2 patients. Images of a patient who underwent noncontrast CT showed stable disease as best response and stable disease on the last available imaging evaluated by RECIST. Radioembolization is safe and effective and led to improved hepatic disease control and overall survival in patients with liver-dominant metastatic RCC. Copyright © 2016 SIR.

    To assess the prognostic and predictive factors of time to treatment failure (TTF) and overall survival (OS), respectively, in patients with metachronous metastatic renal cell carcinoma (mRCC) who were treated with targeted agents. We retrospectively reviewed metachronous mRCC patients, defined as individuals diagnosed with metastatic disease >3 months after initial nephrectomy, treated at an institute since 2005. Cox proportional hazard regression analysis was performed to discover the most determinant variables associated with TTF and OS. Sarcomatoid features, absence of metastasectomy, multiple site metastasis, time to metastasis risk group (0-1 risk factors) did not reach the median OS, whereas the OS for the intermediate (2 risk factors) and high risk groups (3-5 risk factors) were 58.6 and 23.6 months, respectively (prisk criteria models. Initial tumor size or T stage did not affect TTF or OS. Patients who could not undergo metastasectomy and rapidly developed multiple metastases with higher corrected calcium and initial tumors with sarcomatoid features were less likely to benefit from targeted therapy; thus, the new agents under development or clinical trials could be more helpful than the use of standard targeted agents.

    Three dogs were presented for investigation of recurrent pyrexia of unknown origin, chronic vomiting and respiratory distress, respectively. One dog was markedly underweight and the other two were cachexic. Physical examination and initial diagnostic tests failed to establish the underlying cause of the presenting signs. Thoracic radiographs were within normal limits for the age of the dog. In each case there was a high index of suspicion for an occult neoplastic process in view of the profound unexplained weight loss present. High-resolution computed tomography (HRCT) of the thorax was performed. The lung fields were divided into three zones for analysis and a novel classification scheme was used to describe the HRCT findings in each zone. Postmortem examination and histopathology confirmed the presence of an infiltrating metastatic carcinoma in all three cases. The HRCT changes correlated closely with the pathological findings. The authors conclude that HRCT of the lung should be considered for pulmonary metastatic screening in the dog and introduce a classification system for HRCT findings, based on terminology used in human medicine.

    Full Text Available Abstract Background Although numerous chemotherapeutic agents have been tested, the role of systemic chemotherapy for hepatocellular carcinoma (HCC has not been clarified. New therapeutic strategies are thus needed to improve outcomes, and we designed this study with new effective drug combination. Methods Twenty-nine patients with histologically-confirmed, metastatic HCC received a combination chemotherapy with doxorubicin 60 mg/m2 and cisplatin 60 mg/m2 on day 1, plus capecitabine 2000 mg/m2/day as an intermittent regimen of 2 weeks of treatment followed by a 1-week rest. Results The median age was 49 years (range, 32–64 and 19 patients were hepatitis B virus seropositive. Child-Pugh class was A in all patients and 4 had Zubrod performance status of 2. The objective response rate was 24% (95% CI 9–40 with 6 stable diseases. The chemotherapy was generally well tolerated despite one treatment-related death. Conclusion Combination chemotherapy with doxorubicin, cisplatin and capecitabine produced modest antitumor activity with tolerable adverse effects in patients with metastatic HCC.

    Full Text Available Patients with metastatic renal cell carcinoma (RCC to the brain have a very poor prognosis of three months if left untreated. SRS is an effective treatment modality in numerous patients. This case exemplifies the utility of stereotactic radiosurgery (SRS in prolonging survival and maintaining quality of life in a patient with RCC. This 64-year-old female patient initially presented to her primary care physician 22 months after a left nephrectomy for RCC with complaints of mild, intermittent headaches and difficulty with balance. An MRI revealed five cerebellar lesions suspicious for intracranial metastasis. The patient’s first GKRS treatment targeted four lesions with 22 Gy at the 50% isodose line. She underwent a total of seven GKRS treatments over the next 60 months for recurrent metastases to the brain. 72 months and 12 months have now passed since her brain metastases were first discovered and since her last GKRS treatment, respectively, and this woman is alive with considerable quality of life and no evidence of metastatic reoccurrence. This case shows that repeated GKRS treatments, with minimal surgical intervention, can effectively treat multiple intracranial lesions in select patients, prolonging survival and avoiding iatrogenic neurocognitive decline while maintaining a high quality of life.

    2017-09-01

    We report the case of a 42-year-old male patient with mucinous-type metastatic colorectal carcinoma of eight years of evolution. He has received multiple lines of cytostatic treatment with acceptable tolerance and without significant impairment in his quality of life. At present, it is estimated that the overall survival of metastatic colon cancer in cytostatic treatment is around 24 months. However, a small subset of patients may present prolonged survivals of 5 to 10 years after diagnosis, revealing heterogeneity of tumor behavior and response to treatment. Our clinical case represents a long survivor patient despite the advanced stage of his oncological mucinous-colorrectal disease, endorsed in the scientific literature as having worse rates of objective response and less survival. There are different therapeutic approaches that can achieve a significant overall survival. It is essential in clinical practice to use all drugs available to achieve increase of progression-free survival and overall survival, with maintenance of an adequate quality of life.

  9. Late metastatic endometrial carcinoma at the repair site of an abdominal wall incisional hernia

    2017-05-01

    Full Text Available The abdominal wall is a very rare site for endometrial cancer metastases. Its appearance generally indicates advanced cancer with poor prognosis. We report a case of a 55-year-old female who presented with an incisional hernia 4 years after abdominal panhysterectomy for endometrioid adenocarcinoma in 2009. Open hernia mesh repair was performed but on follow-up, she complained of pain and a swelling at the repair site. This was radiologically diagnosed as fibromatosis, but tru-cut biopsy confirmed presence of fibromatosis as well as a metastatic endometrial carcinoma. She was started on neoadjuvant chemotherapy, but had poor response, and therefore, radical excision was performed. She remained well with no metastatic recurrence at 12-month follow-up. This case illustrates late appearance of abdominal wall metastasis from abdomino-pelvic malignancies and highlights the need to exclude the presence of recurrence or metastases prior to surgical repair of incisional hernia occurring after the resection of abdominal or pelvic malignancy.

    2013-04-01

    While basal cell carcinoma (BCC) remains the most common skin cancer, the incidence of metastasis is rare. Most cases of metastatic BCC have been to regional lymph nodes. Metastasis to bone marrow with myelophthisic anemia is especially rare. To our knowledge, there have been only 5 reported cases in literature. We report a sixth case. A 46-year-old male patient presented with an 8 × 7-cm ulcerated plaque on his chest, found to be morpheaform basal cell on pathology. Laboratory findings were notable for normocytic anemia, thrombocytopenia, and elevated LDH. Further work up with bone marrow biopsy revealed tumor cells staining positive for CK AE1/AE3, BerEP4, CK7, CD56, and PIN-4. This confirmed the diagnosis of metastatic BCC (MBCC) to bone marrow. Although the rate of metastasis for BCC is rare, once it occurs, prognosis is poor. MBCC remains a challenge to treat. Therefore, it is critical to resolve the primary BCC and obtain vigilant follow-up, especially in patients with multiple risk factors for MBCC.

    Abstract Our aim was to assess the feasibility and accuracy of contrast-enhanced ultrasound (CEUS) of the breast with SonoVue microbubbles for pre-operative size measurement of invasive breast carcinomas. Seven patients diagnosed with nine invasive breast carcinomas prospectively underwent gray-scale ultrasound and CEUS of the breast according to a standardized protocol. CEUS of the breast was performed by a Philips iU22 scanner equipped with a 4–8 MHz linear array transducer. We used a single dose of 2.4 ml SonoVue as contrast agent. Breast lesion morphology was scored according to the sonographic BI-RADS lexicon criteria and classified accordingly. The greatest tumor dimensions on gray-scale ultrasound and CEUS of the breast were finally compared with the greatest histopathologic tumor sizes. Gray-scale ultrasound underestimated the histopathologic tumor size in 6/9 cases (67%), whereas CEUS of the breast underestimated tumor size in only 3/9 (33%) cases. CEUS of the breast was significantly more accurate for tumor size assessment. Greatest tumor dimension as measured with gray-scale ultrasound of the breast was within 2 mm of the pathologic tumor size in only 2/9 cases (22%), whereas CEUS of the breast accurately assessed tumor size within 2 mm of pathologic tumor size in 6/9 (67%) of the cases (P<0.05). CEUS of the breast proved to be a feasible and safe procedure. It is more accurate than gray-scale ultrasound of the breast for pre-operative size assessment of invasive ductal breast carcinomas.

    This study aimed to document the association of human papilloma virus (HPV) and its types in breast carcinoma tissues in Kuwaiti women, and correlate this with known prognostic markers. The clinicopathological data of archived tissue from 144 cases of invasive ductal breast carcinoma were studied (age, histological grade, size of tumour, lymph node metastases, oestrogen/progesterone receptors and human epidermal growth factor receptor 2 status). HPV frequency was documented using immunohistochemistry (IHC) and chromogenic in-situ hybridisation (CISH). HPV types were documented by CISH using HPV probes. CISH and IHC techniques were compared and HPV correlated with prognostic parameters. The HPV prevalence as determined by CISH and IHC was 51 (35.4%) and 24 (16.7%) cases, respectively. The sensitivity of HPV by IHC was 37.3% and specificity was 94.6%. The sensitivity and specificity of HPV-CISH compared to HPVIHC was statistically significant (P CISH was seen in 51 cases. A combination of HPV 6 and 11, and 16 and 18 was seen in 2 (3.9%) cases, and a combination of HPV 6, 11, 31 and 33 was seen in 7 (13.7%) cases. All three HPV probes: 6 and 11, 16 and 18, as well as 31 and 33 were present in 2 (3.9%) cases. The prevalence of HPVCISH in the Kuwaiti and non-Kuwaiti populations was 27 (52.9%) and 19 (37.2%), respectively. No correlation was observed with the prognostic parameters. The frequency of HPV in breast carcinoma cases in Kuwait was 35.4% (CISH). Of those, 52.9% were Kuwaitis in whom both low- and high-risk HPV types were detected.

    Distant metastases is becoming a more frequently recognized pattern of treatment failure in patients with squamous cell carcinoma of the head and neck (SCCHN). In this study, we evaluated the effect of a dendritic cell (DC)-based vaccine in an early pulmonary metastatic murine model with the aim of providing an effective treatment for SCCHN patients presenting with occult pulmonary metastasis. In vivo animal experiments were conducted in C3H/He immunocompetent mice using the SCCVII syngeneic squamous carcinoma cell line. SCCVII cells were injected through the tail vein to establish early pulmonary metastases. Bone marrow-derived DCs were cultured and educated with ultraviolet B-irradiated apoptotic SCCVII cells before adoptive transfer into the inguinal area. Control groups were vaccinated with normal saline, naïve DCs, or apoptotic tumor cells. In the apoptotic SCCVII-pulsed DC group, the number of pulmonary tumor nodules was reduced, extirpated lung weight was less, and survival was longer than in control groups. Differences were statistically significant (P cells. We hope this study will help improve overall survival of patients with SCCHN, especially when they have early or occult pulmonary metastasis.

    Full Text Available Recently, metastatic renal cell carcinoma (mRCC treatment has changed dramatically with the onset of new therapies against molecular targets replacing immunotherapy as standard treatment. We report the case of a 49-year-old patient with a moderately differentiated renal clear cell carcinoma without extracapsular extension who underwent radical nephrectomy. Eight months after surgery, he developed a thyroid metastasis which was also treated surgically with a hemithyroidectomy. Seventy-five months after nephrectomy, the patient presented an upper gastrointestinal bleeding due to a duodenal metastasis that infiltrates the head of the pancreas. The treatment applied was surgery by duodenopancreatectomy, with positive surgical margins in the pathologic study. In addition to this, the extension study showed lung metastases requiring initiation of systemic treatment with sunitinib. The patient presented an excellent response to treatment, showing complete clinical and radiological response at 5 months of treatment (RECIST criteria and a disease-free survival of 48 months until now, without evidence of toxicity. RCC has the potential to metastasize to almost any location, but thyroid and duodenal metastases in RCC are extremely rare. Moreover, this case also highlights the good responses that can be achieved in terms of disease-free survival, low toxicity and quality of life in this new era of therapies against molecular targets.

    Sunitinib has recently become a standard treatment for metastatic renal cell carcinoma. However, various adverse events have been reported. We present the first case of clinically evident adrenal insufficiency during sunitinib therapy. A 72-year-old man began sunitinib therapy for bilateral lung and adrenal metastases of renal cell carcinoma. His adrenocorticotrophic hormone level was 93.6 pg/ml (7.2-63.3 pg/ml) before sunitinib treatment, indicating that subclinical adrenal insufficiency already existed. Fatigue, which is a frequently seen adverse effect of sunitinib treatment, emerged acutely on Day 24 of the second cycle. Adrenocorticotrophic hormone and free T4 were high and thyroid-stimulating hormone was suppressed. Under the clinical diagnosis of acute adrenal insufficiency with thyrotoxicosis, a low dose of steroid was administered. Fatigue was completely ameliorated by the following morning, although free T4 was still high and thyroid-stimulating hormone was still low. Therefore, hypermetabolism due to thyrotoxicosis unmasked adrenal insufficiency in our case. Physicians should be aware of this rare but potentially fatal complication when severe acute fatigue develops in patients with subclinical adrenal insufficiency.

    The aims of this study were to present the ultrasonographic (US) features of metastatic renal cell carcinoma (RCC) in the thyroid gland and to evaluate the diagnostic utility of fine needle aspiration (FNA) and core needle biopsy (CNB). Eight patients with nine metastatic RCC nodules in the thyroid glands who were treated from January 2002 to March 2015 in a single tertiary hospital were consecutively selected and retrospectively reviewed. US features and clinical history were obtained from the institution’s medical database. FNA was performed nine times on eight nodules and CNB was performed six times on six nodules. The diagnostic utility of FNA and CNB was evaluated. All nine nodules showed mass formation without diffuse thyroid involvement. On ultrasonography, metastatic RCC nodules were solid (100%), hypoechoic (100%), and ovalshaped nodules with a well-defined smooth margin (88.9%) and increased vascularity (100%, with 55% showing extensive vascularity). No calcifications were noted in any nodules. Lymph node metastasis and direct extension to nearby structures beyond the thyroid gland were not found. One FNA (11%) was able to confirm metastatic RCC, whereas all six CNBs confirmed metastatic RCC. Metastatic RCC appears as oval-shaped hypoechoic solid nodules with well-defined smooth margins, no calcifications, and increased vascularity on ultrasonography. Characteristic US features along with a previous history of RCC should raise clinical suspicion, and CNB should be performed to make an accurate diagnosis.

    Full Text Available Aims. Inhibitors of the MET pathway hold promise in the treatment for metastatic kidney cancer. Assessment of predictive biomarkers may be necessary for appropriate patient selection. Understanding MET expression in metastases and the correlation to the primary site is important, as distant tissue is not always available. Methods and Results. MET immunofluorescence was performed using automated quantitative analysis and a tissue microarray containing matched nephrectomy and distant metastatic sites from 34 patients with clear cell renal cell carcinoma. Correlations between MET expressions in matched primary and metastatic sites and the extent of heterogeneity were calculated. The mean expression of MET was not significantly different between primary tumors when compared to metastases (P=0.1. MET expression weakly correlated between primary and matched metastatic sites (R=0.5 and a number of cases exhibited very high levels of discordance between these tumors. Heterogeneity within nephrectomy specimens compared to the paired metastatic tissues was not significantly different (P=0.39. Conclusions. We found that MET expression is not significantly different in primary tumors than metastatic sites and only weakly correlates between matched sites. Moderate concordance of MET expression and significant expression heterogeneity may be a barrier to the development of predictive biomarkers using MET targeting agents.

Patients and methods: Using Surveillance, Epidemiology, and End Results registry data, we selected 56,968 female DCIS patients treated with BCS between 1998 and 2007. Overall survival (OS and breast cancer-specific survival (BCSS were compared among patients who received RT or no RT using the Kaplan–Meier methods and Cox proportional hazards regression models. Results: Median follow-up was 91 months. In the multivariable model, patients receiving postoperative RT had better OS than those undergoing BCS alone (hazard ratio [HR] 0.59, 95% confidence interval [CI] 0.53–0.67, P<0.001. This pattern remained after stratification by estrogen receptor (ER status and age. In contrast, RT delivery was not significantly associated with improved BCSS (HR 0.71, 95% CI 0.48–1.03, P=0.073. However, after stratifying by the above two variables, RT contributed to better BCSS in ER-negative/borderline patients (HR 0.41, 95% CI 0.19–0.88, P=0.023 and younger patients (≤50 years old; HR 0.37, 95% CI 0.15–0.91, P=0.030. Conclusion: Our analysis confirms the beneficial effect of RT on OS in women with locally excised DCIS and reveals the specific protective effect of RT on BCSS in ER-negative/borderline and younger patients.

    Approximately 25% of patients with breast cancer develop cutaneous metastases. Sweat gland carcinomas (SGCs) account for about 0.05% of all cutaneous neoplasms. Cutaneous metastases of breast carcinoma (CMBCs) (especially the ductal type) can be difficult to distinguish from SGCs. Treatment and prognoses for these 2 types of tumors differ radically, making accurate histologic diagnosis crucial. Although a few studies attempt to differentiate these entities employing immunohistochemical (IHC) studies (some of which we review here), to date, no panel of IHC stains exists, to our knowledge, to distinguish these entities. To devise a panel of IHC stains to distinguish CMBC from SGC. Twelve cases of ductal CMBCs (11 not otherwise specified type, and 1 basal phenotype), 11 cases of SGCs (5 eccrine carcinomas, 3 porocarcinomas, and 3 microcystic adnexal carcinomas), 2 benign sweat gland neoplasm cases, and 2 primary breast cancer cases were retrieved and analyzed with the following IHC panel: mammaglobin, gross cystic disease fluid protein (GCDFP) 15, p63, basal cytokeratins (CK5, CK14, and CK17), androgen receptor, and PAX5. The p63 was only weakly expressed in 1 of 12 CMBC cases (8.3%), whereas it was strongly expressed in 10 of 11 SGC cases (90.9%) (P < .001). Basal cytokeratins demonstrated a similar immunoprofile in the SGC group, with 10 of 11 cases (90.9%) expressing all 3 markers, and a variable immunoprofile in the CMBC group with 0% (CK14) (P < .001) to 16.7% (2 of 12 cases; CK5 and CK17) (P < .001) expression. Mammaglobin was expressed in 8 of 12 cases (66.7%) of CMBC. Together, these 5 IHC stains were combined to make a panel that was 100% sensitive and 91% specific in distinguishing between CMBC and SGC.

    Renal cell carcinoma is commonly thought to be a radioresistant malignancy. Retrospective studies report conflicting results on the effect of radiotherapy dose escalation on response and time to progression in symptomatic metastatic disease; studies using the linear quadratic model have used alpha/beta ratios that are inappropriate for slow growing tumours. We aim to describe our experience with palliative radiotherapy in this context, relating Biological Effective Dose to outcome. From December 1995 to April 2001, 143 independent palliative radiotherapy treatments were delivered to 78 patients in a single institution. Retrospective data was obtained on the radiotherapy schedule used, symptom response and time to symptom progression. The biological effective dose (BED) was calculated using alpha/beta ratios of 3 and 7 Gy (BED3 and BED7). The Log-Rank test was used to assess any differences in time to progression, and the Cox Proportional Hazards analysis to determine prognostic factors of time to progression. Overall symptomatic response rate was 73%, with most responses being partial (67%). Forty-three (38%) patients had symptomatic progression after a median follow-up of 425 days. BED (BED3 or BED7) was not significantly different across response types (complete, partial or no response; P=0.90 and 0.88, respectively) and was not predictive for time to symptomatic progression (P=0.99 for BED3 and P=0.70 for BED7). Patients with bone metastases received less total dose (P=0.001), less BED (BED3, P=0.0013, and BED7, P=0.0005) and had a significantly longer time to progression than other sites of metastases (hazard ratio (HR) 0.4; 95% confidence interval (CI) 0.2-0.7; P=0.004). Initial treatment with interferon-alpha alone in patients presenting with metastatic disease, before palliative radiotherapy, was also associated with a shorter time to symptom progression (HR 4.6; 95% CI 1.5-14.1; P=0.007). On removal of these criteria, brain metastases became a significant

    Cyclooxygenase-2 (COX-2) overexpression is implicated in increased risk and poorer outcomes in breast cancer in young women. We investigated COX-2 regulation in normal premenopausal breast tissue and its relationship to malignancy in young women. Quantitative COX-2 immunohistochemistry was performed on adjacent normal and breast cancer tissues from 96 premenopausal women with known clinical reproductive histories, and on rat mammary glands with distinct ovarian hormone exposures. COX-2 expression in the normal breast epithelium varied more than 40-fold between women and was associated with COX-2 expression levels in ductal carcinoma in situ and invasive cancer. Normal breast COX-2 expression was independent of known breast cancer prognostic indicators, including tumor stage and clinical subtype, indicating that factors regulating physiological COX-2 expression may be the primary drivers of COX-2 expression in breast cancer. Ovarian hormones, particularly at pregnancy levels, were identified as modulators of COX-2 in normal mammary epithelium. However, serial breast biopsy analysis in nonpregnant premenopausal women suggested relatively stable baseline levels of COX-2 expression, which persisted independent of menstrual cycling. These data provide impetus to investigate how baseline COX-2 expression is regulated in premenopausal breast tissue because COX-2 levels in normal breast epithelium may prove to be an indicator of breast cancer risk in young women, and predict the chemopreventive and therapeutic efficacy of COX-2 inhibitors in this population.

    Purpose: The purpose of this study was to evaluate BI-RADS indicators in the detection of DCIS by MRI. Materials and methods: Prospective observational study that started in 2014 and lasted 24 months. A total of 110 consecutive patients were evaluated, who presented with suspicious or highly suspicious microcalcifications on screening mammography (BI-RADS categories 4 and 5) and underwent stereotactic-guided breast biopsy, having had an MRI scan performed prior to biopsy. Results: Altogether, 38 cases were characterized as positive for malignancy, of which 25 were DCIS and 13 were invasive ductal carcinoma cases. MRI had a sensitivity of 96%; specificity of 75.67%; positive predictive value (PPV) for DCIS detection of 57.14%; negative predictive value (NPV) in the detection of DCIS of 98.24%; and an accuracy of 80.80%. Conclusion: BI-RADS as a tool for the detection of DCIS by MRI is a powerful instrument whose sensitivity was higher when compared to that observed for mammography in the literature. Likewise, the PPV obtained by MRI was higher than that observed in the present study for mammography, and the high NPV obtained on MRI scans can provide early evidence to discourage breast biopsy in selected cases.

    Full Text Available Objectives. The aim of the study was to develop a clinical prediction model for assessing the probability of having invasive cancer in the definitive surgical resection specimen in patients with biopsy diagnosis of ductal carcinoma in situ (DCIS of the breast, to facilitate decision making regarding axillary surgery. Methods. In 349 women with DCIS, predictors of invasion in the definitive resection specimen were identified. A model to predict the probability of invasion was developed and subsequently simplified to divide patients into two risk categories. The model’s performance was validated on another patient population. Results. Multivariate logistic regression revealed four independent predictors of invasion: (i suspicious (microinvasion in the biopsy specimen; (ii visibility of the lesion on ultrasonography; (iii size of the lesion on mammography >30 mm; (iv clinical palpability of the lesion. The actual frequency of invasion in the high-risk patient group in the test and validation population was 52.6% and 48.3%, respectively; in the low-risk group it was 16.8% and 7.1%, respectively. Conclusion. The model proved to have good performance. In patients with a low probability of invasion, an axillary procedure can be omitted without a substantial risk of additional surgery.

    Purpose To determine the relationship of microcalcification morphology and distribution with clinical, histopathologic, biologic features and local recurrence (LR) in patients with pure ductal carcinoma in situ (DCIS) of the breast. Methods All patients with pure DCIS who underwent preoperative mammography at our institution from 1996 through 2009 were identified. Mammographic findings were classified according to the ACR BI-RADS lexicon. Associations between mammographic findings and clinical, histopathologic, biologic characteristics and LR were analyzed. Statistical inference used multiple logistic regression and Cox proportional hazards regression adjusted for age and confounding due to bias from nonrandomized selection of radiation therapy. Results We identified 1657 patients with microcalcifications visualized on mammography. The mean age at diagnosis was 55 years (SD, 11). The mean follow-up was 7 years (range, 1–16). Ipsilateral LR was 4% in segmentectomy (987) and 1.5% in mastectomy (670) patients. Increased LR risk was seen in patients with dense breast tissue (pmicrocalcifications were associated with 5.2-fold increase in LR. Extremely dense breast tissue was associated with positive/close margins (p=0.04) and multicentricity (pbreast tissue (pbreast tissue, large DCIS size, and fine linear (branching) microcalcifications were associated with increased LR, yet overall LR rates remained low. Extremely dense breast tissue was a risk factor for multicentricity and positive margins in DCIS. PMID:26416712

    Recent discussion has suggested that some cases of ductal carcinoma in situ (DCIS) with high risk of invasive disease may require sentinel lymph node biopsy (SLNB). Systematic literature review identified 48 studies (9,803 DCIS patients who underwent SLNB). Separate analyses for patients diagnosed preoperatively by core sampling and patients diagnosed postoperatively by specimen pathology were conducted to determine the percentage of patients with axillary nodal involvement. Patient factors were analyzed for associations with risk of nodal involvement. The mean percentage of positive SLNBs was higher in the preoperative group (5.95% vs 3.02%; P = .0201). Meta-regression analysis showed a direct association with tumor size (P = .0333) and grade (P = .00839) but not median age nor tumor upstage rate. The SLNB should be routinely considered in patients with large (>2 cm) high-grade DCIS after a careful multidisciplinary discussion. In the context of breast conserving surgery, the SLNB is not routinely indicated for low- and intermediate-grade DCIS, high-grade DCIS smaller than 2 cm, or pure DCIS diagnosed by definitive surgical excision.

    Worldwide, breast cancer is one of the frequently diagnosed cancers in women with high mortality if not diagnosed at early stage. Although biomarker discoveries through various proteomic approaches have been studied in breast cancer, a limited number of studies have explored the invasive ductal carcinoma with Luminal B HER2 positive (LB) and HER2 enriched (HE) subtypes. The present study employed the complementary quantitative proteomic approaches to find a panel of markers that could discriminate LB and HE subtypes as well as early (ES) and late stages (LS) of these subtypes. A total of 67 and 68 differentially expressed proteins were identified by DIGE for the subtype and stage wise categories, respectively. Multivariate statistical analysis was employed to identify the set of most significant proteins, which could discriminate between these two subtypes and also early and late stages under study. Immunoblotting and MRM based validation in a separate cohort of samples confirmed that panel of biosignatures for LB are APOA1, GELS, HS90B, EF1A1, NHRF1 and PRDX3 and for HE are PRDX1, CATD, CALR, ATPB and CH60. For the diagnosis of early and late stages the potential markers are TPM4, CATD, PRDX3, ANXA3, HSPB1 and CALR, TRFE, GELS, CH60, CAPG, NHRF1, 1433G, GRP78 respectively. Copyright © 2015 Elsevier B.V.

And we combined MLNR and depth of invasion to investigate whether prognosis of SCC can be predicted better.  Patients and methods: We performed a retrospective review of patients with SCC who underwent radical hysterectomy and pelvic lymphadenectomy at QiLu Hospital of Shandong University from January 2007 to December 2009. Prognostic factors for disease-free survival (DFS and overall survival (OS were identified by univariate and multivariate analyses.  Results: One hundred and ninety-eight patients met the inclusion criteria and were included in the analysis. By cut-point survival analysis, MLNR cutoff was designed as 0.2. On multivariate analysis, an MLNR >0.2 was associated with a worse OS (hazard ratio [HR] =2.560, 95% CI 1.275–5.143, P=0.008 and DFS (HR =2.404, 95% CI 1.202–4.809, P=0.013. Depth of invasion cutoff was designed as invasion >1/2 cervix wall and was associated with a worse OS (HR =1.806, 95% CI 1.063–3.070, P=0.029 and DFS (HR =1.900, 95% CI 1.101–3.279, P=0.021. In addition, subgroup analysis revealed significant difference in OS and DFS rates between different MLNR categories within the same depth of invasion category (P<0.05, however, not between different depth of invasion categories within the same MLNR category (P>0.05.  Conclusion: MLNR may be used as the independent prognostic parameter in patients with SCC.

    Treatment options for patients with platinum-refractory, recurrent, metastatic head and neck squamous cell carcinoma (r/m HNSCC) are limited and prognosis is poor. The recent CheckMate 141 clinical trial demonstrated that nivolumab, an anti-programmed cell death protein 1 monoclonal antibody, was efficacious in extending the median overall survival (OS) in this patient population compared with standard therapies. We conducted a cost-effectiveness analysis to determine whether nivolumab is a cost-effective treatment in this patient population and examined various subgroups to determine for which, if any, the treatment is more cost-effective. We implemented a state transition model for HNSCC with a patient cohort who had tumor progression 6 months after the last dose of platinum-containing chemotherapy and compared the cost-effectiveness of nivolumab with docetaxel. Treatment effect estimates and adverse event rates were obtained from CheckMate 141. Costs, utilities, and other model inputs were gathered from published sources. We used a Canadian perspective, a 5-year time horizon, and a 1.5% discount rate for the analysis. Nivolumab extended mean OS by 4 months compared with docetaxel and resulted in fewer treatment-related adverse events, producing an incremental effectiveness of 0.13 quality-adjusted life years (QALY). The incremental cost of treatment with nivolumab was $18,823. At a willingness-to-pay threshold of $100,000/QALY, nivolumab was not a cost-effective treatment option for r/m HNSCC, with an incremental cost-effectiveness ratio of $144,744/QALY. Nivolumab would be cost-effective if its price was reduced by 20%. Our subgroup analysis seemed to indicate that nivolumab might be cost-effective for tumors with expression of programmed death-ligand 1 >5%. We conclude that although nivolumab offers clinical benefit for the treatment of r/m HNSCC over current regimens, it is not cost-effective based on its list price. We have also established a value

    We assessed the co-expression of cell cycle-related biomarkers in a series of 121 consecutive cases of high-grade ductal carcinoma in situ (DCIS), pure or associated with invasive carcinoma, and their associations with the different immunoprofiles of DCIS. Cases were identified from the histopathology files of the Breast Pathology Laboratory, Federal University of Minas Gerais, Brazil, from 2003 to 2008. The expression of estrogen receptor, progesterone receptor, HER2 overexpression, cytokeratin 5, epidermal growth factor receptor 1, cyclooxygenase-2, p16 and Ki67 were assessed. Tumors were placed into five subgroups according to their immunohistochemical profile: luminal A, luminal B, HER2, basal-like and "not classified". We found that the basal phenotype was associated with a higher frequency of p16-positive cases (83%) and the luminal A phenotype showed a higher frequency of p16-negative cases (93%; p=0.000). The association of biomarkers p16(+)/Ki67(+)/COX2(+) was expressed in 02/06 cases (33.3%) of the basal phenotype but in only 01/70 cases (1.4%) of the luminal A phenotype (p=0.01). The co-expression of p16(+)/Ki67(+)/COX2(-) was associated with a basal phenotype (p=0.004). P16 expression, p16(+)/Ki67(+)/COX2(+) and p16(+)/Ki67(+)/COX2(-) co-expression showed significant associations with the basal phenotype and these profiles could be used to guide more aggressive treatment strategies in patients with high-grade DCIS. © The Author(s) 2015.

    Aim: To determine whether the extent of microcalcification and ductal carcinoma in situ (DCIS) grade can be used to accurately predict the presence and size of invasive cancer in cases of malignant microcalcification. Materials and methods: Over a 10-year period, 402 cases of malignant microcalcification from an NHS screening programme were analysed. For each case, measurement of mammographic microcalcification extent, DCIS grade, and the presence and size of invasive carcinoma from the excised surgical specimen were recorded. Results: The final histological diagnosis was DCIS only in 71% (284/402) and DCIS with a focus of invasive disease in 29% (118/402). The risk of invasive disease increased with increasing size of microcalcification from 20% (27/136) for cluster size less than 11 mm, to 45% (18/40) for cluster size more than 60 mm. The risk of invasive disease also increased with increasing histological grade of DCIS from 13% (4/31) with low-grade DCIS to 36% (86/239) with high-grade DCIS. There were significant associations with the presence of invasive disease for cluster size (p = 0.0001) and DCIS grade (p = 0.003), and when using univariate analysis with simple [cluster size (p = 0.01) and grade (p = 0.01)] and multiple [cluster size (p = 0.02) and grade (p = 0.02)] logistic regression, respectively. The Hosmer-Lemeshow goodness-of-fit test suggests that the multiple logistic regression model has a good fit (p = 0.99). Conclusion: The multidisciplinary team can use these data in individual cases to estimate the risk of invasive cancer and decide whether to carry out an axillary staging procedure.

    Full Text Available OBJECTIVES: To assess the quality of the currently available clinical practice guidelines (CPGs for hepatocellular carcinoma, and provide a reference for clinicians in selecting the best available clinical protocols. METHODS: The databases of PubMed, MEDLINE, Web of Science, Chinese Biomedical Literature database (CBM, China National Knowledge Infrastructure (CNKI, WanFang, and relevant CPGs websites were systematically searched through March 2014. CPGs quality was appraised using the Appraisal of Guidelines for Research & Evaluation (AGREE II instrument, and data analysis was performed using SPSS 13.0 software. RESULTS: A total of 20 evidence-based and 20 expert consensus-based guidelines were included. The mean percentage of the domain scores were: scope and purpose 83% (95% confidence interval (CI, 81% to 86%, clarity of presentation 79% (95% CI, 73% to 86%, stakeholder involvement 39% (95% CI, 30% to 49%, editorial independence 58% (95% CI, 52% to 64%, rigor of development 39% (95% CI, 31% to 46%, and applicability 16% (95% CI, 10% to 23%. Evidence-based guidelines were superior to those established by consensus for the domains of rigor of development (p<0.001, clarity of presentation (p = 0.01 and applicability (p = 0.021. CONCLUSIONS: The overall methodological quality of CPGs for hepatocellular carcinoma and metastatic liver cancer is moderate, with poor applicability and potential conflict of interest issues. The evidence-based guidelines has become mainstream for high quality CPGs development; however, there is still need to further increase the transparency and quality of evidence rating, as well as the recommendation process, and to address potential conflict of interest.

    Discordance in the receptor status between primary breast carcinomas (PBC) and corresponding metastasis is well documented. Interrogation of the receptor status of metastatic breast carcinoma (MBC) in cytology material is common practice; however, its utility has not been thoroughly validated. We studied patients with MBC, and evaluated the concordance rates of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2) between PBC surgical specimens and corresponding MBC cell blocks (CBs). We correlated the findings with clinicopathologic variables and with the fixation methods used. We searched for patients with MBC diagnosed on cytology from 2007 to 2009 and selected those with ER, PR and HER2 tested in both the PBC surgical specimens and the MBC CBs. We included CBs fixed in formalin and methanol based solution (CytoLyt®). All slides were reevaluated by cytopathologists. Clinical information was retrieved from the medical records. We studied 65 patients with PBC and MBC paired specimens. The concordance rates between PBC and MBC were 78.5%, 58.5% and 96.9%, for ER, PR and HER2, respectively. When discordant, PR status switched from positive (PBC) to negative (MBC) in most cases (23/27). The PR concordance rate was 45.2% for CBs fixed in formalin and 70.6% for those fixed with CytoLyt® (p=0.047). The ER, PR and HER2 concordance rates between the PBC and MBC CBs are similar to those reported in paired surgical specimens. PR status was the most prevalent discordance and was not accompanied by a switch in ER.

    Insulin-like growth factor binding protein-3 (IGFBP-3) differentially modulates breast epithelial cell growth through insulin-like growth factor (IGF)-dependent and IGF-independent pathways and is a direct (IGF-independent) growth inhibitor as well as a mitogen that potentiates EGF (epidermal growth factor) and interacts with HER-2. Previously, high IGFBP-3 levels in breast cancers have been determined by enzyme-linked immunosorbent assay and immunoradiometric assay methods. In vitro, IGFBP-3's mechanisms of action may involve cell membrane binding and nuclear translocation. To evaluate tumour-specific IGFBP-3 expression and its subcellular localisation, this study examined immunohistochemical IGFBP-3 expression in a series of invasive ductal breast cancers (IDCs) with synchronous ductal carcinomas in situ (DCIS) in relation to clinicopathological variables and patient outcome. Immunohistochemical expression of IGFBP-3 was evaluated with the sheep polyclonal antiserum (developed in house) with staining performed as described previously. IGFBP-3 was evaluable in 101 patients with a variable pattern of cytoplasmic expression (positivity of 1+/2+ score) in 85% of invasive and 90% of DCIS components. Strong (2+) IGFBP-3 expression was evident in 32 IDCs and 40 cases of DCIS. A minority of invasive tumours (15%) and DCIS (10%) lacked IGFBP-3 expression. Nuclear IGFBP-3 expression was not detectable in either invasive cancers or DCIS, with a consistent similarity in IGFBP-3 immunoreactivity in IDCs and DCIS. Positive IGFBP-3 expression showed a possible trend in association with increased proliferation (P = 0.096), oestrogen receptor (ER) negativity (P = 0.06) and HER-2 overexpression (P = 0.065) in invasive tumours and a strong association with ER negativity (P = 0.037) in DCIS. Although IGFBP-3 expression was not an independent prognosticator, IGFBP-3-positive breast cancers may have shorter disease-free and overall survivals, although these did not reach

    Metastatic colorectal carcinoma to the liver remains a formidable challenge. Responses to chemotherapy are brief and the number of effective drugs is very limited. A phase II trial of hepatic hyperthermia and intraarterial chemotherapy was undertaken to attempt to improve response rates and duration. Patients were given a 10 day course of IA 5-FU at 15 mg/kg. During the infusion hyperthermia was given five times using the BSD Annular Phased Array (APA). Thermistors were placed percutaneously into normal liver and tumor using ultrasound or CT scan guidance. Six patients have been treated. Significant problems in positioning ill patients in the APA were encountered, and there was difficulty also in preventing heating throughout the abdominal cavity. Four patients, all with poor performance status, failed to benefit. One patient had improvement in liver function studies for two months and failed to respond on a repeat course. One patient had a complete response which is continuing over 18 months with a liver scan reverting to normal and CEA returning to normal. These preliminary results are promising and warrant further trials

    Benua, Leeper, and others (BEL) have advocated the estimation of radiation exposure to the blood to select a more rational maximum safe dose of radioiodine (dosimetry) to treat metastatic functioning well-differentiated thyroid carcinoma. After adopting the BEL dosimetry approach, we reviewed the immediate (during hospitalization) and intermediate (from discharge up to 3 mo) side effects after our initial 15 therapies in ten patients. The doses ranged from 51 mCi (1887 MBq) to 450 mCi (16.65 GBq). Immediate side effects were observed in 12/15 (80%), are described in detail, and were as follows: gastrointestinal 10/15, salivary 9/15, nonsalivary neck pain, swelling, etc. 2/15, pulmonary 0/15. Intermediate side effects were observed in 10/15 (67%), are described in detail, and were as follows: gastrointestinal 0/15, salivary 3/15, nonsalivary neck pain, swelling, etc. 3/15, nasal complaints 2/15, transient bone marrow suppression 9/10, pulmonary 0/15. No patient required blood transfusions or had complications secondary to reduced blood counts. All patient complaints resolved; however, several patients may have reduced baseline blood counts one year after therapy. No other long-term side effect has been noted but the mean follow-up has been only 15 mo. In our opinion, we have not observed any side effect to date which would contraindicate the continued use and evaluation of the BEL dosimetry approach

    Analysis of a large local autopsy collective to gather epidemiological and histopathological data on hepatocellular carcinoma (HCC). We examined a large dataset of 44,104 autopsies performed at the Institute of Pathology, Basel, Switzerland, including 2 autopsy collectives (1969-1983 and 1988-2012) to gather current data on HCC in the advanced stage. A total of 398 HCC were diagnosed, accounting for around 1% of all autopsies. As expected, most patients developing HCC had advanced stages of liver fibrosis or cirrhosis (F3/F4). However, in the more recent autopsy collective (1988-2012), our data also show an increase of HCC arising in livers without or with only mild to moderate fibrosis (F0-F2). Extrahepatic metastasis was found in 156 of 398 HCC (39.1%), with lung metastasis (74.5%) being the most common, followed by the bones (24.8%) and adrenal glands (19.1%). Our data therefore seem to suggest that, in the last 2 decades, despite the introduction of new therapeutic modalities for HCC, no significant changes have been observed regarding the metastatic pattern of advanced HCC. © 2016 S.

    Clear cell renal cell carcinoma (ccRCC) is the most common type of kidney cancer and it forms highly vascularized tumors. The monocyte endoribonuclease MCPIP1 negatively regulates inflammation by degrading mRNA encoding proinflammatory cytokines, such as IL6, IL1, and IL12. MCPIP1 is also a negative regulator of NFκB and AP1 activity and it influences a broad range of miRNA activities. Here we report that MCPIP1 protein levels are decreased during renal cancer progression. In patient-derived tumors and xenografts established in NOD-SCID or nude mice, low MCPIP1 levels correlated strongly with increased proliferation, tumor outgrowth, and vascularity. MCPIP1 activity regulated secretion of VEGF, IL8, and CXCL12 leading to chemotaxis of microvascular endothelial cells, phosphorylation of VE-cadherin, and increased vascular permeability. Mechanistic investigations showed that MCPIP1 regulated ccRCC cell motility, lung metastasis, and mesenchymal phenotype by regulating key elements in the EMT signaling axis. Overall, our results illuminate how MCPIP1 serves as a key nodal point in coordinating tumor growth, angiogenesis, and metastatic spread in ccRCC.

    Lobular neoplasia (LN) represents a spectrum of atypical proliferative lesions, including atypical lobular hyperplasia and lobular carcinoma-in-situ. The need for excision for LN found on core biopsy (CB) is controversial. We conducted a prospective multi-institutional trial (TBCRC 20) to determine the rate of upgrade to cancer after excision for pure LN on CB. Patients with a CB diagnosis of pure LN were prospectively identified and consented to excision. Cases with discordant imaging and those with additional lesions requiring excision were excluded. Upgrade rates to cancer were quantified on the basis of local and central pathology review. Confidence intervals and sample size were based on exact binomial calculations. A total of 77 of 79 registered patients underwent excision (median age 51 years, range 27-82 years). Two cases (3%; 95% confidence interval 0.3-9) were upgraded to cancer (one tubular carcinoma, one ductal carcinoma-in-situ) at excision per local pathology. Central pathology review of 76 cases confirmed pure LN in the CB in all but two cases. In one case, the tubular carcinoma identified at excision was also found in the CB specimen, and in the other, LN was not identified, yielding an upgrade rate of one case (1%; 95% CI 0.01-7) by central pathology review. In this prospective study of 77 patients with pure LN on CB, the upgrade rate was 3% by local pathology and 1% by central pathology review, demonstrating that routine excision is not indicated for patients with pure LN on CB and concordant imaging findings.

    The authors evoke some characteristics of the basal cell carcinoma (slow evolution, local morbidity) and report and discuss the case of a giant basal cell trunk carcinoma, associated with several symptoms (pain, bleeding, anaemia), already metastatic at the moment of diagnosis, and locally treated by irradiation. Due to its size and expansion, this carcinoma was considered as inoperable. An external radiotherapy has been performed and resulted in a significant clinical tumour reduction. But the metastatic risk is high in such cases. Radiotherapy is then a therapeutic option for a local treatment with a durable efficiency. Short communication

    To establish an animal model of spontaneous cervical lymph node metastasis of laryngeal squamous cell carcinoma and obtain laryngocarcinoma cells with high metastatic potential, laryngeal squamous cell carcinoma cell line HEP-2 in logarithmic phase were inoculated under the lingual margin mucosa of nude mice. HEP-2 cells metastasized to the cervical lymph nodes were isolated, cultured, and re-inoculated under the lingual margin mucosa of nude mice twice. The tumor formation in the tongue and in the cervical lymph nodes was confirmed by pathological examination. Carcinoma cells' ability of invasion and migration was detected by transwell assay. Human specific Alu sequences were detected by PCR, which indicated that the tumor cells originated from human laryngeal squamous cell carcinoma cell line HEP-2. Finally, an animal model of spontaneous lymph node metastasis of laryngeal squamous cell carcinoma was successfully established. Laryngeal squamous cell carcinoma cells with high metastatic potential to lymph nodes were obtained through repeated inoculations. .

    Full Text Available There is a paucity of data regarding molecular subtypes of pure ductal carcinoma in situ (pDCIS. We evaluated the expression of ER, PR, HER2, Ki67, and p53 and DNA ploidy in 118 pDCIS and 100 invasive breast carcinomas (IBCAs by routine IHC and classified them according to molecular subtypes. Quantification of biomarkers and DNA ploidy was performed by image analysis. Expression of ER, PR, and high ki67 was more frequent in pDCIS compared to IBCA. High-grade tumors had lower ER and PR expression, high Ki67, overexpression of HER2 and p53, and DNA aneuploidy. Luminal A and HER2 subtypes were more common in pDCIS, and triple negative was more prevalent in IBCA. In both groups, HER2 and triple negative subtypes were characterized by high ki67, overexpression of p53, and DNA aneuploidy compared to luminal subtypes. Molecular subtypes of IBCA are distinct from those of pDCIS. Invasion is characterized by change in phenotype in some tumors.

    Vibrational signatures of human breast tissue (invasive ductal carcinoma and invasive lobular carcinoma) were used to identify, characterize and discriminate structures in normal (noncancerous) and cancerous tissues by confocal Raman imaging, Raman spectroscopy and IR spectroscopy. The most important differences between normal and cancerous tissues were found in regions characteristic for vibrations of carotenoids, fatty acids, proteins, and interfacial water. Particular attention was paid to the role played by unsaturated fatty acids and their derivatives. K-means clustering and basis analysis followed by PCA and PLSDA is employed to analyze Raman spectroscopic maps of human breast tissue and for a statistical analysis of the samples (82 patients, 164 samples). Raman maps successfully identify regions of carotenoids, fatty acids, and proteins. The intensities, frequencies and profiles of the average Raman spectra differentiate the biochemical composition of normal and cancerous tissues. The paper demonstrates that Raman imaging has reached a clinically relevant level in regard to breast cancer diagnosis applications. The sensitivity and specificity obtained directly from PLSLD and cross validation are equal to 90.5% and 84.8% for calibration and 84.7% and 71.9% for cross-validation respectively.

    Full Text Available Myoepithelial neoplasms of the soft tissues are a rare, heterogeneous group of tumors for which classification continues to evolve. While well defined within salivary glands, they can also arise in viscera and soft tissues, where diagnosis is challenging due to the lack of clinical and pathological familiarity. We present the case of a 36 year old man with myoepithelial carcinoma arising as a primary tumor within the soft tissues of the neck, which metastasized to the cecum, causing intussusception. This spindle cell neoplasm showed the classic S100 protein, smooth muscle actin and pancytokeratin-positive immunoprofile. Metastasis of myoepithelial carcinoma to the cecum has not been previously described, and coupled with the spindle cell morphology, may cause significant diagnostic difficulty in the absence of clinical familiarity, particularly as there is morphologic overlap with spindle cell neoplasms arising more commonly in gastrointestinal sites, including gastrointestinal stromal tumor, leiomyosarcoma and sarcomatoid carcinoma.

    Chronic lymphedema presents as interstitial fluid retention due to a failure in the lymphatic system drainage. The affected region becomes more vulnerable immunologically and predisposed to the onset of neoplasms. Basal Cell Carcinoma is the most common sort of neoplasm, nevertheless it rarely metastisizes. Sarcomas are malignant mesenchymal neoplasms, locally aggressive, which can spread. Here is reported an infrequent case of multiple basal cell carcinoma, synchronous to a poorly differentiated pleomorphic sarcoma, both spreading to lymph nodes and arising from tissue compromised by chronic lymphedema.

We want to share our experience about the treatment choice. A 27-year-old man was diagnosed with nasopharyngeal nonkeratinizing carcinoma in August 2004. In March 2013 he underwent a thyroid carcinoma radical operation, and histological examination revealed metastasis to the thyroid gland from nasopharyngeal carcinoma. An 18F-FDG-PET/CT scan and biopsy showed metastatic abdominal lymph nodes of nasopharyngeal carcinoma in April 2015. A 27-year-old man was diagnosed with metastasis of nasopharyngeal carcinoma to the thyroid gland with subsequent metastatic abdominal lymph nodes. The patient was treated with concurrent chemotherapy and radiotherapy for nasopharyngeal carcinoma and metastasis to the thyroid gland. The metastases to the abdominal lymph nodes received chemotherapy. After 6 cycles of chemotherapy with gemcitabine, cisplatin, and 5-fluorouracil for metastasis to the abdominal lymph nodes, the patient is currently asymptomatic with stable disease and improved quality of life. The treatment choice for metastasis of nasopharyngeal carcinoma depends on the clinical disease extent, and surgery and/or chemo-radiation therapy must be drafted to the individual patient in order to improve the prognosis and quality of life.

    Full Text Available Renal cell carcinoma (RCC comprises a heterogenous group of tumors. Traditionally, papillary RCC (pRCC is associated with a favorable outcome compared to clear cell RCC (ccRCC, while other series report equivalent or worse prognosis. In this paper we comparatively evaluate outcome of pRCC versus ccRCC in two large multi-institutional databases (cohort study, including distribution of pRCC subtypes 1 and 2. Retrospective data of 1,943 surgically treated pRCC patients from 17 European/ North American centers between 1984-2015 were compared to 5,600 ccRCC patients from a database comprising 11 European/ North American centers (1984-2011. Median follow-up was 64.6 months. Differences between pRCC, subtypes, and ccRCC were compared with t-tests, Chi^2-tests, and exact Fisher tests. Cancer-specific mortality was analyzed with cumulative incidence curves and Cox cause-specific hazard models. The robustness of our results was examined with sensitivity analyses. We present that cancer-specific mortality rates and variables as stage, lymph node, and distant metastasis differ significantly between groups. Furthermore, we demonstrate that patients with non-metastatic pRCC had a significantly better cancer-specific mortality (HR 0.76, p = 0.007, when compared to ccRCC. Additionally, pRCC type 2 versus ccRCC exhibited no difference in cancer-specific mortality (HR 0.9, p = 0.722, whereas pRCC type 1 versus ccRCC displayed a risk of death reduced by 69% (p = 0.044. Taken together, outcome of pRCC versus ccRCC varies significantly in non-metastatic disease. Furthermore, pRCC type 2 exhibited no difference in cancer-specific mortality, whereas pRCC type 1 displayed a significantly reduced risk of death. Consequently, there is urgent need to respect histopathological entities and their subtypes, when assigning follow-up or targeted therapy to RCC patients.

    Pancreatic cancer is the fourth leading cause of cancer related death with median survival ranging from 3 to 6 months for metastatic disease. Palliative chemotherapy has been the backbone of treatment in advanced stage and has evolved over time. Data pertaining to the disease are scarce from our part of the world where treatment poses a significant challenge due to lack of resources. A retrospective chart review was performed for all patients presenting with stage IV pancreatic carcinoma at a tertiary care hospital in Karachi, Pakistan between January 2008 and December 2012. Data were collected using a pre-designed, coded questionnaire looking at patient characteristics, treatment given and outcome. 101 patients were found to be eligible. Mean age was 56.7 ± 12.8 years, the male to female ratio was 2:1 and most patients had a good performance status. More than half of the tumors were located in the head (57%, n=58) and almost all were adenocarcinomas (95%, n=96). Some 58% (n=59) received first line chemotherapy of which 49% (n=29) received gemcitabine-based regimens and 39% (n=23) received FOLFIRINOX. The median progression free survival for gemcitabine based treatment was 2.9 months (IQR=1.6-5.6) as opposed to 7.3 months (IQR=4.5-9.2) for FOLFIRINOX (P=0.02). Median overall survival was 4.9 months (IQR=2.3-9.5) for first line gemcitabine based treatment and 10.5 months (IQR=7.0-13.2) for first line FOLFIRINOX therapy (P=0.002). Patients on FOLFIRINOX had better survival across all subgroups. Inpatient admissions and dose reductions were more frequent with FOLFIRINOX but the difference between the two regimens was not statistically significant. FOLFIRINOX could be successfully administered as outpatient therapy to a number of patients. FOLFIRINOX remains a suitable first line option in patients with metastatic pancreatic cancer with good performance status even in a resource-poor country where diagnostic and supportive care facilities may be less than optimal and

    Metastatic cutaneous squamous cell carcinoma of the head and neck (cHNSCC) is more common in older patients. It is postulated that the age-related decline in immunity plays a role in cancer predisposition and prognosis. We aimed to investigate the effect of age on outcomes in cHNSCC and compare these with the outcomes of patients with cHNSCC and known immunosuppression. Patients with metastatic cHNSCC treated with curative intent were identified from a prospectively collated database of head and neck cancers at the Sydney Head and Neck Cancer Institute. Patients with cHNSCC with known immunosuppression provided a comparison group for analysis of disease-specific outcomes. The study cohort includes 418 immunocompetent patients with metastatic cHNSCC (median age: 73 years (interquartile range: 65-81 years)) and the control cohort includes 24 patients with metastatic cHNSCC and immunosuppression (median age: 51 years (interquartile range: 42-62 years)). Increasing age was not associated with poorer disease-free or disease-specific survival. Patients in older age groups (70 years and over) had better disease-specific outcomes than patients with long-term immunosuppression. Patterns of disease failure did not differ between different age groups. The number of positive nodes and extra-capsular spread were the only significant prognostic variables in multivariable analysis. In the context of metastatic cHNSCC, age should not be considered as a marker of poor prognosis. Age should not be considered a surrogate marker of immune function considering the poorer outcomes seen in patients with immunosuppression. Older patients with metastatic cHNSCC should be considered candidates for standard treatment if otherwise medically fit. © 2016 Royal Australasian College of Surgeons.

A case of mRCC was reported which recurred after surgery and roferon treatment. The patient was treated with apatinib at a dose of 500 mg orally, twice daily, 28 days/cycle. The metastatic lesions improved based on computed tomography after apatinib administration in the fourth and eighth month. The progression-free survival of the patient had increased almost to 8 months. The patient showed a good tolerance with only an adverse effect of mild-to-moderate hand-foot syndrome which was managed well. Apatinib is an option for mRCC after previous treatment. However, more and larger trials are still needed. Keywords: metastatic renal cell carcinoma, apatinib, sunitinib, sorafenib, vascular endothelial growth factor receptor

    Metastases to breast are much rarer than primary breast tumors. We now present a case of 45-year-old female, who presented with an isolated breast mass. A positron emission tomography-computed tomography (PET-CT) done revealed hypermetabolic right breast nodules, soft tissue deposits, and multiple nodal involvement. The biopsy from the breast and axillary lymph node showed dense lymphoid infiltrate and was interpreted initially as granulomatous inflammation. However, the lumps were hard and suspicious for primary breast cancer, so an immunohistochemistry for cytokeratin was performed which highlighted the epithelial cell clusters masked within the inflammatory infiltrate and the diagnosis of undifferentiated carcinoma, lymphoepithelioma-like was made. After the diagnosis was made, it was realized that the patient had been treated earlier for a nasopharyngeal carcinoma (NPC). The in situ hybridization (ISH) test for Epstein-Barr virus-encoded RNA ISH was positive in the tumor cells, and hence, a diagnosis of metastatic NPC was finally made. The patient subsequently developed extensive nodal, skeletal, and soft tissue metastatic disease but was alive till September 2015. Although extremely rare, metastatic NPC can occur in the breast and the above case highlights that it mimics an inflammatory lesion. This case highlights the importance of the multidisciplinary approach for appropriate tumor diagnosis and patient management.

    The purpose of this study was to retrospectively evaluate the feasibility of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) to differentiate between ductal carcinoma in situ (DCIS) and mastopathy by analyzing their time-intensity curves (TICs) using the two-compartment pharmacokinetic model with an assumption of instantaneous injection of contrast medium (TCPM). After the pre-contrast MRI was performed using a 1.5 T MRI system, DCE-MRI was performed four times after the intravenous administration of contrast medium. We set the volumes of interest (VOIs) on the tumor and normal mammary gland, and obtained the TICs in these VOIs. We calculated the following parameters by fitting these TICs to the equation derived from TCPM; the initial slope of the TIC (Slope ini ), the area under the TIC (AUC), the time to peak enhancement (TTP) and the peak enhancement (PeakE). We calculated these parameters in both the lesion and normal mammary gland and the ratios of the parameters in the lesion to those in the normal gland (rSlope ini , rAUC, rTTP and rPeakE). There were significant differences in Slope ini (P = 0.009), PeakE (P = 0.019), rSlope ini (P = 0.010), and rTTP (P = 0.005) between DCIS and mastopathy. The areas under the receiver operating characteristic curve for Slope ini , PeakE, rSlope ini , and rTTP were 0.67 ± 0.06 (P = 0.009), 0.65 ± 0.06 (P = 0.019), 0.67 ± 0.06 (P = 0.01), and 0.68 ± 0.06 (P = 0.005), respectively. In conclusion, our results suggest that analysis of TICs obtained by DCE-MRI using TCPM appears to be useful for differentiating between DCIS and mastopathy.

    Purpose: Given the paucity of data on racial disparities in ductal carcinoma in situ (DCIS), the data from a multi-institutional cohort of DCIS patients treated with breast-conserving surgery and whole breast radiation therapy (RT) were analyzed to determine whether racial disparities or differences exist. Methods and Materials: A total of 533 white and 76 black DCIS patients from 3 university-based cancer centers were uniformly treated with breast-conserving surgery and RT. All patient data were collected and analyzed as a function of race. Results: The median follow-up was 5.2 years. No significant racial differences were seen in tumor size, age at diagnosis, estrogen receptor status, necrosis, or grade (all P>.05). Of the treatment parameters, the RT dose delivered, boost, positive margin rates, frequency of hormone receptor status assessment, and receipt of hormonal therapy for the 2 cohorts did not significantly differ (all P>.05). The local relapse-free survival was similar at 5 years (96.1% and 98.1%, P=.399) and 10 years (92.8% vs 95.8%, P=.360), with no significant overall survival difference at 10 years (94.0% vs 88.9%, P=.290) between the white and black patients, respectively. On multivariate analysis, race was not an independent predictor of local relapse-free survival or overall survival when accounting for age, grade, and margin status. Conclusion: In our large cohort of DCIS patients uniformly treated at 3 institutions with breast conservation without any apparent differences in treatment delivery parameters, we demonstrated that the clinical and pathologic features and local survival outcomes did not differ as a function of race. Our results suggest that when black patients with DCIS are appropriately selected for breast conservation and receive adjuvant RT without racial disparities in the treatment parameters, differences in the outcomes as a function of race do not exist.

    The aim of this study was to investigate the utility of echo intensity and contrast enhancement in the differential diagnosis between intraductal papillary mucinous neoplasm with an associated invasive carcinoma (IPMN-IC) and pancreatic ductal adenocarcinoma (PDAC) on ultrasonography. This study included eight and 37 patients who had pathologically confirmed IPMN-IC and PDAC, respectively, and were enrolled for a comparative analysis of the sonographic features of the tumors. In the quantitative echo intensity evaluation, the two groups were compared with respect to the difference between the tumor intensity and the pancreatic intensity (TI-PI) and between the tumor intensity and the vascular intensity (TI-VI). In the quantitative contrast enhancement evaluation, the increase in echo intensity (ΔTI) and increase in echo intensity per unit of time (slope) were compared between the groups. The echo intensity and contrast enhancement were also compared between the two groups in patients with T3-T4 disease. In addition, the correlations of the histological type, tumor size, stromal type, and T factor with echogenicity and contrast enhancement were analyzed. IPMN-IC had significantly greater echo intensity and contrast enhancement than PDAC (TI-PI, P=0.004; TI-VI, P=0.001; ΔTI, P=0.012; slope, P=0.002). In T3-T4 disease, IPMN-IC also showed greater echo intensity and faster enhancement than PDAC. Echo intensity and contrast enhancement were correlated with histological type (TI-PI, P=0.003; TI-VI, P<0.001; ΔTI, P=0.007; slope, P<0.001). IPMN-IC and PDAC can be differentiated by the quantitative evaluation of echo intensity and contrast enhancement.

    Objectives: To identify preoperative features that could be used to predict invasive breast cancer in women with a diagnosis of ductal carcinoma in situ (DCIS) at ultrasound (US)-guided 14-gauge core needle biopsy (CNB). Methods: A total of 86 DCIS lesions that were diagnosed at US-guided 14-gauge CNB and excised surgically in 84 women were assessed. We retrospectively reviewed the patients’ medical records, mammography, US, and MR imaging. We compared underestimation rates of DCIS for the collected clinical and radiologic variables and determined the preoperative predictive factors for upstaging to invasive cancer. Results: Twenty-seven (31.4%) of 86 DCIS lesions were upgraded to invasive cancer. Preoperative features that showed a significantly higher underestimation of DCIS were palpability or nipple discharge (p = 0.040), number of core specimens less than 5 (p = 0.011), mammographic maximum lesion size of 25 mm or larger (p = 0.022), mammographic mass size of 40 mm or larger (p = 0.046), sonographic mass size of 32 mm or larger (p = 0.009), lesion size of 30 mm on MR (p = 0.004), lower signal intensity (SI) on fat-saturated T2-weighted MR images (FS-T2WI) (p = 0.005), heterogeneous or rim enhancement on MR images (p = 0.009), and apparent diffusion coefficient (ADC) values lower than 1.04 × 10{sup −3} mm{sup 2}/s on diffusion-weighted MR imaging (DWI) (p < 0.001). Conclusion: Clinical symptom of palpability or nipple discharge, number of core specimen, mammographic maximum lesion or mass size, SI on FS-T2WI, heterogeneous or rim enhancement on MR, and ADC value may be helpful in predicting the upgrade to invasive breast cancer for DCIS diagnosed at US-guided 14-gauge CNB.

    Full Text Available Abstract Background To investigate whether Radiation therapy (RT should follow breast conserving surgery in women with ductal carcinoma in situ from breast cancer (DCIS with objective of decreased mortality, invasive or non invasive recurrence, distant metastases and contralateral breast cancer rates. We have done a meta-analysis of these results to give a more balanced view of the total evidence and to increase statistical precision. Methods A meta-analysis of randomized controlled trials (RCT was performed comparing RT treatment for DCIS of breast cancer to observation. The MEDLINE, EMBASE, CANCERLIT, Cochrane Library databases, Trial registers, bibliographic databases, and recent issues of relevant journals were searched. Relevant reports were reviewed by two reviewers independently and the references from these reports were searched for additional trials, using guidelines set by QUOROM statement criteria. Results The reviewers identified four large RCTs, yielding 3665 patients. Pooled results from this four randomized trials of adjuvant radiotherapy showed a significant reduction of invasive and DCIS ipsilateral breast cancer with odds ratio (OR of 0.40 (95% CI 0.33 – 0.60, p Conclusion The conclusion from our meta-analysis is that the addition of radiation therapy to lumpectomy results in an approximately 60% reduction in breast cancer recurrence, no benefit for survival or distant metastases compared to excision alone. Patients with high-grade DCIS lesions and positive margins benefited most from the addition of radiation therapy. It is not yet clear which patients can be successfully treated with lumpectomy alone; until further prospective studies answer this question, radiation should be recommended after lumpectomy for all patients without contraindications.

    Whether a systemic adjuvant treatment is needed is an area of controversy in patients with node-negative early breast cancer with tumor size of ≤1 cm, including T1mic. We performed a retrospective analysis of clinical and pathology data of all consecutive patients with node-negative T1mic, T1a, and T1b invasive ductal carcinoma who received surgery between Jan 2000 and Dec 2006. The recurrence free survival (RFS) and risk factors for recurrence were identified. Out of 3889 patients diagnosed with breast cancer, 375 patients were enrolled (T1mic:120, T1a:93, T1b:162). Median age at diagnosis was 49. After a median follow up of 60.8 months, 12 patients developed recurrences (T1mic:4 (3.3%), T1a:2 (2.2%), T1b:6 (3.7%)), with a five-year cumulative RFS rate of 97.2%. Distant recurrence was identified in three patients. Age younger than 35 years (HR 4.91; 95% CI 1.014-23.763, p = 0.048) and triple negative disease (HR 4.93; 95% CI 1.312-18.519, p = 0.018) were significantly associated with a higher rate of recurrence. HER2 overexpression, Ki-67, and p53 status did not affect RFS. Prognosis of node-negative breast cancer with T1mic, T1a and T1b is excellent, but patients under 35 years of age or with triple negative disease have a relatively high risk of recurrence

    Full Text Available Introduction. This is an extremely rare case of a patient with metastatic follicular thyroid cancer who continued to produce thyroid hormone and was iodine scan positive without stimulation after thyroidectomy and radioiodine (I-131 therapy. Patient Findings. A 76-year-old Caucasian male was diagnosed with metastatic follicular thyroid carcinoma on lung nodule biopsy. Total thyroidectomy was performed and he was ablated with 160 mCi of I-131 after recombinant human thyrotropin (rhTSH stimulation. Whole body scan (WBS after treatment showed uptake in bilateral lungs, right sacrum, and pelvis. The thyroglobulin decreased from 2,063 to 965 four months after treatment but rapidly increased to 2,506 eleven months after I-131. Thyroid stimulating hormone (TSH remained suppressed and free T4 remained elevated after I-131 therapy without thyroid hormone supplementation. He was treated with an additional 209 mCi with WBS findings positive in lung and pelvis. Despite I-131, new metastatic lesions were noted in the left thyroid bed and large destructive lesion to the first cervical vertebrae four months after the second I-131 dose. Conclusions. This case is exceptional because of its rarity and also due to the dissociation between tumor differentiation and aggressiveness. The metastatic lesions continued to secrete thyroid hormone and remained radioiodine avid with rapid progression after I-131 therapy.

    Full Text Available Relapse and metastasis are two key risk factors of hepatocellular carcinoma (HCC prognosis; thus, it is emergent to develop an early and accurate detection method for prognostic evaluation of HCC after surgery. In this study, we sought to acquire oligonucleotide DNA aptamers that specifically bind to HCC cells with high metastatic potential. Two HCC cell lines derived from the same genetic background but with different metastatic potential were employed: MHCC97L (low metastatic properties as subtractive targets and HCCLM9 (high metastatic properties as screening targets. To mimic a fluid combining environment, initial DNA aptamers library was firstly labelled with magnetic nanoparticles using biotin-streptavidin system and then applied for aptamers selection. Through 10-round selection with subtractive Cell-SELEX, six aptamers, LY-1, LY-13, LY-46, LY-32, LY-27/45, and LY-7/43, display high affinity to HCCLM9 cells and do not bind to MHCC97L cells, as well as other tumor cell lines, including breast cancer, lung cancer, colon adenocarcinoma, gastric cancer, and cervical cancer, suggesting high specificity for HCCLM9 cells. Thus, the aptamers generated here will provide solid basis for identifying new diagnostic targets to detect HCC metastasis and also may provide valuable clues for developing new targeted therapeutics.

Methods: Twenty mGEP-NEC patients were treated with cisplatin or carboplatin/etoposide between April 2010 and October 2014. Both large-cell and small-cell histologies were included. Cisplatin 25 mg/m2 was administered on days 1–3 followed by etoposide 100 mg/m2 on days 1–3 every 21 days. Carboplatin 300 mg/m2 was administered on day 1 followed by etoposide 100 mg/m2 on days 1–3. Results: Of the 19 evaluable patients, 13 obtained a partial response, four showed stable disease, and two progressed. Median overall survival (mOS was 13.5 months and median progression-free survival (mPFS was 10.9 months. Gallium-68 positron emission tomography/computerizsed tomography-positive patients had a higher, albeit not significantly, OS than those with negative results (75% vs 34.3% at 18 months; P=0.06. mPFS was 19.3 and 6.3 months (P<0.01 in mGEP-NEC patients with Ki67 ≤55% or >55%, respectively. mOS was 8.1 months in the latter group but was not reached in the Ki67 ≤55% group (P-value =0.039. Patients with a lower body mass index (BMI had a better prognosis in terms of both OS and PFS. Patients with BMI ≥25 had a mOS of 11.7 months (P=0.0293 and a mPFS of 6.2 months (P=0.0057.

    The initial and follow-up CT and MRI images of ten patients with hepatic metastases from ovarian tumors were retrospectively analyzed to establish their features and sequential changes in appearance. Ten patients with hepatic metastasis from ovarian tumors received initial and follow-up CT and MRI examinations. Six patients were followed up every two to three weeks before surgical tumor resection. Both CT and MR images were analyzed by two radiologists. A total of fourteen lesions were detected by CT and MRI in 10 patients. All 14 lesions were demonstrated as areas of marked hyperintensity on T2-weighted MRI. Eleven cyst-like tumors were demonstrated as round or oval low density lesions on CT and as areas of hypointensity on T1-weighted imaging. Three lesions were shown as solid masses with slightly low attenuation at the initial CT examination and slightly low or iso-intensity areas on T1-weighted imaging, and these lesions showed early peripheral globular enhancement and delayed enhancement on contrast-enhanced CT and MR imaging. Cystic formation was observed two to three weeks later after initial study in all the 3 solid lesions. Rapid subcapsular effusion, which showed obvious enhancement on delayed Gd-DTPA enhanced MR imaging, was observed in two patients. The hepatic metastatic tumor from cystic ovarian carcinoma may manifest as a well-defined cystic lesion or as a solid mass, and the solid mass shows delayed enhancement on contrast-enhanced CT and MR imaging. Furthermore, rapid cystic formation and rapid subcapsular extension is frequently seen. (author)

    Sunitinib is a tyrosine kinase inhibitor (TKI) used in treatment of metastatic renal cell carcinoma (mRCC), gastrointestinal stromal tumors and pancreatic neuroendocrine tumors. One of the most common side effects related to sunitinib is hypothyroidism. Recent trials suggest correlation between the incidence of hypothyroidism and treatment outcome in patients treated with TKI. This study evaluates whether development of hypothyroidism is a predictive marker of progression-free survival (PFS) in patients with mRCC treated with sunitinib. Twenty-seven patients diagnosed with clear cell mRCC, after nephrectomy and in 'good' or 'intermediate' MSKCC risk prognostic group, were included in the study. All patients received sunitinib as a first-line treatment on a standard schedule (initial dose 50 mg/day, 4 weeks on, 2 weeks off). The thyroid-stimulating hormone serum levels were obtained at the baseline and every 12 weeks of treatment. In statistic analyses, we used Kaplan-Meier method for assessment of progression-free survival; for comparison of survival, we used log-rank test. In our study, the incidence of hypothyroidism was 44%. The patients who had developed hypothyroidism had better median PFS to patients with normal thyroid function 28,3 months [95% (CI) 20.4-36.2 months] versus 9.8 months (6.4-13.1 months). In survival analysis, we perceive that thyroid dysfunction is a predictive factor of a progression-free survival (PFS). In the unified group of patients, the development of hypothyroidism during treatment with sunitinib is a positive marker for PFS. During that treatment, thyroid function should be evaluated regularly.

    Adrenocortical carcinoma (ACC) is a rare malignancy with generally poor outcomes and limited treatment options. While surgical resection can be curative for early local disease, most patients present with advanced ACC owing to nonspecific symptoms. For those patients, treatment options include systemic chemotherapy and locoregional therapies including radiofrequency ablation and transarterial chemoembolization. We present the first reported case of utilizing yttrium-90 microsphere selective internal radiation therapy (SIRT) in combination with first line EDP-M (Etoposide, Doxorubicin, Cisplatin, Mitotane) chemotherapy and debulking surgical primary tumor resection for treatment of metastatic ACC. Stable complete radiologic response has been maintained after twelve months with resolution of clinical symptoms. These findings prompt the need for further consideration and studies to elucidate the role of SIRT in combination with systemic and surgical treatment for metastatic ACC.

    To investigate the associations of diabetes mellitus with recurrence and prognosis after surgery for non-metastatic renal cell carcinoma and the effect modification of obesity on the above relationships. We retrospectively evaluated 543 patients with non-metastatic renal cell carcinoma (pT1-4N0M0) who underwent radical or partial nephrectomy. The association of diabetes mellitus with recurrence was analyzed using the Kaplan-Meier method and the Cox regression model. We also examined whether the above relationships were modified by obesity using subgroup analysis and tests of interaction. For subgroup analysis, the body mass index was categorized as non-obese (obese (≥25 kg/m(2)). Eighty-two patients (15.1%) had a history of diabetes mellitus. During the mean follow-up of 66.7 months, 68 patients (12.5%) developed recurrence. Although the body mass index was not associated with recurrence, diabetes mellitus was an independent predictor of recurrence in multivariate analysis (hazard ratio 2.43, P = 0.003), along with tumor diameter, grade and pathological T stage. In further subgroup analysis, the same relationship between diabetes mellitus and recurrence was clearly shown in the obese group (hazard ratio 4.07, P = 0.010), but not in the non-obese group (hazard ratio 1.95, P = 0.125). At the same time, obesity modified the effect of diabetes mellitus on recurrence with a trend (P-interaction = 0.086). In the obese group, 5-year recurrence-free survival rates were 75.3 and 91.9% for diabetes mellitus and non-diabetes mellitus patients, respectively (P Diabetes mellitus is a predictor of recurrence following surgery for non-metastatic renal cell carcinoma, especially in obese patients.

    The goal of this study was to examine time-dependent effects of prognostic biomarkers of systemic inflammation in patients with metastatic renal cell carcinoma. Retrospective chart reviews were conducted at the Winship Cancer Institute of Emory University and the Atlanta Veterans Administration Medical Center with authorization from the Emory University Institutional Review Board and the Veterans Administration Research and Development Committee. Inclusion criteria included age ⩾18 years, treatment with targeted therapy for clear cell or non-clear cell metastatic renal cell carcinoma and concomitant assessment of C-reactive protein and albumin levels on ⩾3 occasions that were ⩾10 days apart. Discovery, expansion, and external validation cohorts were identified. Established prognostic variables were evaluated by univariate and multivariate analyses. Intensity of systemic inflammation was assessed at all time points with C-reactive protein and albumin as prognostic covariates for overall survival in an extended Cox regression model. Intensity of systemic inflammation was assessed on 3186 occasions in 181 patients. Risk status changed in 131 patients (72%). The hazard ratio for overall survival was 21.41 (95% confidence interval = 8.26-55.50) with a type 3 p value of inflammation were compared to all other time points. The bias-corrected c-statistic was 0.839 (0.773-0.905) and 0.818 (0.691-0.946), respectively. Terminal disease progression with severe systemic inflammation was detected in 87% of the 90 patients who died. In conclusion, time-dependent effects are a prominent feature of intensity of systemic inflammation, a powerful prognostic biomarker for metastatic renal cell carcinoma.

    Full Text Available Objective  To evaluate the clinical efficacy, the immune function and follow-up observation of autologous dendritic cells (DCs combined with cytokine-induced killer (CIK cells in the treatment of metastatic renal cell carcinoma. Methods  Peripheral blood mononuclear cells (PBMCs were collected from 27 patients with metastatic renal cell carcinoma, and cultured in vitro to produce DCs and CIK cells. After sterility test, phenotypic characterization by flow cytometry and cell count, the produced DCs and CIK cells were then returned to the patient. DCs were given subcutaneously on day 7, 9, 11 and 13 respectively, after PBMCs collection, and CIK cells were given intravenously on day 11 and 13 respectively. This treatment regimen was repeated at a 3 months interval until the disease progresses. Clinical outcomes and immune function were recorded during the treatment period. Results  After DCs-CIK cells treatment, clinical efficacy showed an objective response rate (ORR of 37%, a disease control rate (DCR of 85% and 2 years overall survival rate of 81.5%. There were no significant changes of T cell subsets including CD3 +CD4+CD8–, CD3+CD4–CD8+, CD3+CD19–, CD3–CD19+, CD3–CD16+CD56+, CD3+CD16+CD56+, CD3+HLA-DR–, CD3+HLA-DR+, CD3+CD28+CD8+ and Th2 cells except CD3+CD4+CD25+ T cells (Treg cells and Th1 in peripheral blood between pre-and post-treatment. No serious adverse events were observed. Conclusion  DCs-CIK cells immunotherapy provides a safe and effective treatment approach for patients with metastatic renal cell carcinoma, and may improve the immunosuppression status and enhance the anti-tumor immunity without obvious adverse reaction.

    Full Text Available Abstract Background Recent studies suggest an association between chronic inflammation, modulating the tissue microenvironment, and tumor biology. Tumor environment consists of tumor, stromal and endothelial cells and infiltrating macrophages, T lymphocytes, and dendritic cells, producing an array of cytokines, chemokines and growth factors, accounting for a complex cell interaction and regulation of differentiation, activation, function and survival of tumor and surrounding cells, responsible for tumor progression and spreading or induction of antitumor immune responses and rejection. Tumor Necrosis Factor (TNF family members (19 ligands and 29 receptors represent a pleiotropic family of agents, related to a plethora of cellular events from proliferation and differentiation to apoptosis and tumor reduction. Among these members, BAFF and APRIL (CD257 and CD256 respectively gained an increased interest, in view of their role in cell protection, differentiation and growth, in a number of lymphocyte, epithelial and mesenchymal structures. Methods We have assayed by immunohistochemistry 52 human breast cancer biopsies for the expression of BAFF and APRIL and correlated our findings with clinicopathological data and the evolution of the disease. Results BAFF was ubiquitely expressed in breast carcinoma cells, DCIS, normal-appearing glands and ducts and peritumoral adipocytes. In contrast, APRIL immunoreactive expression was higher in non-malignant as compared to malignant breast structures. APRIL but not BAFF immunoreactivity was higher in N+ tumors, and was inversely related with the grade of the tumors. Neither parameter was related to DFS or the OS of patients. Conclusion Our data show, for the first time, an autocrine secretion of BAFF and APRIL from breast cancer cells, offering new perspectives for their role in neoplastic and normal breast cell biology and offering new perspectives for possible selective intervention in breast cancer.

    In a biennial screening mammography programme, we analysed the trends in incidence of screen-detected DCIS and invasive breast cancers in the era of screen-film mammography (SFM) screening, the period of the transition to full-field digital mammography (FFDM) screening and the period of FFDM screening. We also investigated a possible association between the incidence and grading of screen-detected DCIS and invasive breast cancer. In the southern part of the Netherlands, FFDM screening gradually replaced SFM screening between May 2009 and April 2010. We included a consecutive series of 484, 422 screens obtained between July 2005 and July 2015 and divided these screens into three groups; SFM-only cohort, transition cohort and FFDM-only cohort. A total of 3059 referred women were diagnosed with DCIS (n = 623) or invasive breast cancer (n = 2436). The majority of DCIS were high-grade (48.2%), whereas the majority of the invasive breast cancers were low-grade (45.4%) or intermediate-grade (41.6%). The cancer detection rate (CDR) per 1000 screened women showed the same distribution by grade in both groups. The transition to FFDM was characterised by an increased overall detection rate of invasive cancers. Screening mammography detects mostly high-grade DCIS and low- or intermediate-grade invasive cancers. The grade distribution as well as the CDR in the years after the introduction of FFDM remained stable compared to the era of SFM screening. By diagnosing and treating high-grade DCIS, which otherwise may develop into high-grade invasive carcinoma, our findings provide new evidence for the beneficial value of screening mammography programmes.

    A patient with progressively worsening thyrotoxicosis, refractory to medical therapy, is described. Repeated measurements of thyroidal RAI uptake over a 13 month period were low consistently and could not be explained by iodine ingestion, thyroiditis, or administration of exogenous thyroid hormone. An I-131 scan ultimately revealed striking activity at the base of the skull, reflecting ectopic excessive production of thyroid hormone by a solitary functioning metastatic thyroid carcinoma. The thyrotoxic state resolved after large doses of therapeutic I-131. Typical features of this rare cause of hyperthyroidism are discussed

    Full Text Available Purpose: The aim of this article is to illustrate the diagnostic challenges and management of paraneoplastic neurological syndromes in Merkel cell carcinoma. Materials and Methods: We describe a previously functionally independent 85-year-old woman who presented with subacute onset of dizziness and gait ataxia in the setting of metastatic Merkel cell carcinoma. Results: Diagnosis was made on biopsy after positron emission tomography imaging revealed increased metabolic activity in 2 left inguinofemoral lymph nodes. Cerebrospinal fluid analysis was positive for anti-Hu on subsequent admission. Her functional status improved with methylprednisolone treatment and radiotherapy. Conclusion: The case highlights the challenge of the evaluation of patients who present with progressive cerebellar signs and the need to consider a paraneoplastic syndrome, especially in the setting of previous malignancy.

    Full Text Available Abstract Background Multiple primary cancers have a low incidence particularly when cancers are synchronous. Few cases of synchronous head and neck cancer and breast carcinoma are reported in the literature. Case presentation We report here an exceptional case of a 47 years old Moroccan woman presenting two synchronous cancers, the first in the nasopharynx and the second in the breast. The patient was treated successfully with a combined strategy associating chemotherapy, radiation therapy, and surgery. She remains disease free after 27 months of follow up. Conclusions Treatment strategy in the case of multiple primary cancers remains controversial because of the variety of presentations; initial aggressive treatment reports good results.

    Full Text Available Extrapulmonary small cell carcinomas (EPSCC are rare malignancies with poor patient prognoses. We present the case of a 63-year-old male who underwent surgical resection of a poorly differentiated small cell carcinoma, likely from a small intestinal primary tumor that metastasized to the cerebellopontine angle (CPA. A 63-year-old male presented with mild left facial paralysis, hearing loss, and balance instability. MRI revealed a 15 mm mass in the left CPA involving the internal auditory canal consistent with a vestibular schwannoma. Preoperative MRI eight weeks later demonstrated marked enlargement to 35 mm. The patient underwent a suboccipital craniectomy and the mass was grossly different visually and in consistency from a standard vestibular schwannoma. The final pathology revealed a poorly differentiated small cell carcinoma. Postoperative PET scan identified avid uptake in the small intestine suggestive of either a small intestinal primary tumor or additional metastatic disease. The patient underwent whole brain radiation therapy and chemotherapy and at last follow-up demonstrated improvement in his symptoms. Surgical resection and radiotherapy are potential treatment options to improve survival in patients diagnosed with NET brain metastases. We present the first documented case of skull base metastasis of a poorly differentiated small cell carcinoma involving the CPA.

    Data on sequential therapy in patients with metastatic renal cell carcinoma (mRCC) and intrinsic resistance to receptor tyrosine kinase inhibitor (rTKI) treatment remains vague. We retrospectively studied treatment characteristics and outcome of mRCC patients refractory to first rTKI therapy. Thirty-five mRCC patients (male, 18; female, 11) with primary resistance to first rTKI therapy (sunitinib, n = 28; sorafenib, n = 7) and a median treatment interval of 2.4 months (1 - 4.6) were identified. In 22 patients, progressive disease (PD) was determined by a new metastatic lesion. Of these, 16 patients received subsequent therapy with 12 patients remaining refractory and 4 patients achieving disease stabilization. In 13 patients continuous growth of existing metastatic lesions determined PD. Of these, 9 received sequential therapy with 6 achieving disease stabilization. Altogether, 25 patients were treated sequentially (rTKI: n = 15; mTOR-inhibitor: n = 10) and achieved a median PFS of 3.2 months (range, 1-16.6). Fifteen patients failed to respond to either line of therapy. Disease control was not associated with type of subsequent therapy. Median OS was 14.9 months (CI: 5.5-24.4). Intrinsic resistance to rTKI is associated with a low chance of response to sequential therapy and a poor prognosis in mRCC patients

    Epstein-Barr virus (EBV)-encoded latent membrane proteins (LMPs) expedite progression of EBV-relevant cancers. Of the full set of LMPs, latent membrane protein 1 (LMP1) was identified to uniquely augment store-operated Ca(2+) entry (SOCE). Previously, we reported that the suppression of SOCE exhibited inhibitory effects on cell migration and the extravasation from vasculature in EBV-negative nasopharyngeal carcinoma (NPC) cells. In this follow-up study, we aimed to expand our understanding of the modulation of SOCE by LMP1 and test the possibility that blockage of LMP1-modulated SOCE affects the LMP1-promoted metastatic potential. Here we showed that suppressions of the LMP1-boosted SOCE blunted the LMP1-promoted cell migration, VEGF-mediated angiogenesis and permeabilization in vitro. Blockage of SOCE inhibited vasculature-invasion of circulating cells and distant metastatic colonization in vivo. Notably, utilizing VEGFR2-EGFP-tag zebrafish we revealed that the LMP1-expressing cells arrested in a small-caliber vessel mobilized surrounding endothelial cells to facilitate vasculature-invasion. Thus, the LMP1-boosted SOCE promotes metastatic potential of NPC cells by solidifying their collaborations with the nearby non-cancer cells through the manipulation of oncogenic Ca(2+) signaling. Our study highlights the advantage of using both conventional mammal and transgenic zebrafish for developing a novel therapeutic strategy targeting the multiple steps of invasion-metastasis cascade.

    The value of screen detection and treatment of ductal carcinoma in situ (DCIS) is a matter of controversy. At present, the extent to which the diagnosis and treatment of DCIS could prevent the occurrence of invasive breast cancer in the future is not clear. We sought to estimate the association between detection of DCIS at screening and invasive interval cancers subsequent to the relevant screen. We obtained aggregate data for screen-detected cancers from 84 local screening units within 11 regional Quality Assurance Reference Centres in England, Wales, and Northern Ireland from the National Health Service Breast Screening Programme. Data for DCIS diagnoses were obtained for women aged 50-64 years who were invited to and attended mammographic breast screening from April 1, 2003, to March 31, 2007 (4 screening years). Patient-level data for interval cancer arising in the 36 months after each of these were analysed by Poisson regression with invasive interval cancer screen detection rate as the outcome variable; DCIS detection frequencies were fitted first as a continuous and then as a categorical variable. We repeated this analysis after adjustment with both small size and high-grade invasive screen-detected cancers. We analysed data for 5,243,658 women and on interval cancers occurring in the 36 months after the relevant screen. The average frequency of DCIS detected at screening was 1·60 per 1000 women screened (median 1·50 [unit range 0·54-3·56] [corrected to] per 1000 women). There was a significant negative association of screen-detected DCIS cases with the rate of invasive interval cancers (Poisson regression coefficient -0·084 [95% CI -0·13 to -0·03]; p=0·002). 90% of units had a DCIS detection frequency within the range of 1·00 to 2·22 per 1000 women; in these units, for every three screen-detected cases of DCIS, there was one fewer invasive interval cancer in the next 3 years. This association remained after adjustment for numbers of small screen

    Purpose: Whole-breast radiation therapy (XRT) after breast-conserving surgery (BCS) for ductal carcinoma in situ (DCIS) may decrease the risk of local recurrence, but the optimal dose regimen remains unclear. Past studies administered 50 Gy in 25 fractions (conventional); however, treatment pattern studies report that hypofractionated (HF) regimens (42.4 Gy in 16 fractions) are frequently used. We report the impact of HF (vs conventional) on the risk of local recurrence after BCS for DCIS. Methods and Materials: All women with DCIS treated with BCS and XRT in Ontario, Canada from 1994 to 2003 were identified. Treatment and outcomes were assessed through administrative databases and validated by chart review. Survival analyses were performed. To account for systematic differences between women treated with alternate regimens, we used a propensity score adjustment approach. Results: We identified 1609 women, of whom 971 (60%) received conventional regimens and 638 (40%) received HF. A total of 489 patients (30%) received a boost dose, of whom 143 (15%) received conventional radiation therapy and 346 (54%) received HF. The median follow-up time was 9.2 years. The median age at diagnosis was 56 years (interquartile range [IQR], 49-65 years). On univariate analyses, the 10-year actuarial local recurrence–free survival was 86% for conventional radiation therapy and 89% for HF (P=.03). On multivariable analyses, age <45 years (hazard ratio [HR] = 2.4; 95% CI: 1.6-3.4; P<.0001), high (HR=2.9; 95% CI: 1.2-7.3; P=.02) or intermediate nuclear grade (HR=2.7; 95% CI: 1.1-6.6; P=.04), and positive resection margins (HR=1.4; 95% CI: 1.0-2.1; P=.05) were associated with an increased risk of local recurrence. HF was not significantly associated with an increased risk of local recurrence compared with conventional radiation therapy on multivariate analysis (HR=0.8; 95% CI: 0.5-1.2; P=.34). Conclusions: The risk of local recurrence among individuals treated with HF regimens

    Epigenetic mechanisms such as DNA methylation are being increasingly recognized to play an important role in cancer and may serve as a cancer biomarker. The aim of this study was to evaluate the promoter methylation status of MGMT (O6-methylguanine-DNA methyltransferase) and a possible correlation with the expression of MGMT and standard clinicopathological parameters in invasive ductal breast carcinoma patients (IDC) of Kashmir. Methylation-specific PCR was carried out to investigate the promoter methylation status of MGMT in breast tumors paired with the corresponding normal tissue samples from 128 breast cancer patients. The effect of promoter methylation on protein expression in the primary breast cancer and adjacent normal tissues was evaluated by immunohistochemistry (n = 128) and western blotting (n = 30). The frequency of tumor hypermethylation was 39.8 % and a significant difference in methylation frequency among breast tumors were found (p MGMT in 68/128 (53.1 %) tumors. MGMT promoter methylation mediated gene silencing was associated with loss of its protein expression (rs = -0.285, p = 0.001, OR = 3.38, 95 % CI = 1.59-7.17). A significant correlation was seen between loss of MGMT and lymph node involvement (p = 0.030), tumor grade (p MGMT methylation was found to be associated with tumor grade (p = 0.011), tumor stage (p = 0.009), and loss of ER (p = 0.003) and PR receptors (p = 0.009). To our knowledge, our findings, for the first time, in Kashmiri population, indicate that MGMT is aberrantly methylated in breast cancer and promoter hypermethylation could be attributed to silencing of MGMT gene expression in breast cancer. Our data suggests that MGMT promoter hypermethylation could have a potential function as molecular biomarker of breast oncogenesis. Also, based on their predictive value of response to therapy, the immunohistochemical evaluation and interpretation of MGMT may also help in future to

    A 67-year-old Taiwanese female presented to our institution in November 1997 with gastric signet ring cell carcinoma, pT2N0M0, status post subtotal gastrectomy. In February 2003 she was diagnosed with left breast invasive lobular carcinoma status post modified radical mastectomy, pT2N2M0. Further examination in January 2005 revealed proximal transverse colon cancer, Dukes' C2, with status post right hemicolectomy. She achieved disease-free status from all three malignancies after surgical resection and adjuvant chemotherapy for breast and colon cancers sequentially. In November 2011, she complained about sudden onset of gross hematuria for several days. Diagnostic cystoscopy showed a mass lesion over her urinary bladder. Cystoscope-assisted biopsy showed metastatic poorly differentiated adenocarcinoma with signet ring appearance. Herein we have discussed the pathologic role in the diagnosis of metastatic tumor involving a patient with multiple primary cancers. We also explored the epidemiologic risk and potential causal mechanism of patients with multiple primary cancers.

    Full Text Available Kinases are therapeutically actionable targets. Kinase inhibitors targeting vascular endothelial growth factor receptors (VEGFR and mammalian target of rapamycin (mTOR improve outcomes in metastatic clear cell renal cell carcinoma (ccRCC, but are not curative. Metastatic tumor tissue has not been comprehensively studied for kinase gene expression. Paired intra-patient kinase gene expression analysis in primary tumor (T, matched normal kidney (N and metastatic tumor tissue (M may assist in identifying drivers of metastasis and prioritizing therapeutic targets. We compared the expression of 519 kinase genes using NanoString in T, N and M in 35 patients to discover genes over-expressed in M compared to T and N tissue. RNA-seq data derived from ccRCC tumors in The Cancer Genome Atlas (TCGA were used to demonstrate differential expression of genes in primary tumor tissue from patients that had metastasis at baseline (n = 79 compared to those that did not develop metastasis for at least 2 years (n = 187. Functional analysis was conducted to identify key signaling pathways by using Ingenuity Pathway Analysis. Of 10 kinase genes overexpressed in metastases compared to primary tumor in the discovery cohort, 9 genes were also differentially expressed in TCGA primary tumors with metastasis at baseline compared to primary tumors without metastasis for at least 2 years: EPHB2, AURKA, GSG2, IKBKE, MELK, CSK, CHEK2, CDC7 and MAP3K8; p<0.001. The top pathways overexpressed in M tissue were pyridoxal 5'-phosphate salvage, salvage pathways of pyrimidine ribonucleotides, NF-kB signaling, NGF signaling and cell cycle control of chromosomal replication. The 9 kinase genes validated to be over-expressed in metastatic ccRCC may represent currently unrecognized but potentially actionable therapeutic targets that warrant functional validation.

    Full Text Available Background. Thorough study of the molecular genetic alterations in patients with hereditary and sporadic renal cell carcinoma (RCC enabled to reveal potential therapeutic targets - vascular endothelial growth factor (VEGF, platelet-derived growth factor (PDGF, growth factor receptors (VEGFR, PDGFR, EGFR, FGFR, mTOR signaling protein. Advances in targeted therapy treatment in the current therapeutic practice have brought a problem of its rational use and ultimately effective outcomes. The main solution of solving this problem is to establish independent clinical and laboratory prognostic factors and molecular markers which could predict the efficacy of targeted therapy.Objective – optimization of targeted therapy in patients with RCC by using both molecular and genetic prognostic factors as predictors of the treatment efficacy.Materials and methods. We assessed the level of mRNA expression of 13 potential target genes in primary tumor and metastatic site of patients suffering from metastatic RCC (n = 43 and evaluated the influence of the selected genes’ expression on the therapeutic efficacy of mTOR inhibitors and VEGFR inhibitors.Conclusion. VEGFR1 mRNA overexpression in metastatic site as well as mTOR and/or PI3K mRNA overexpression could be assessed as potential biomarkers in predicting the treatment efficacy of VEGFR inhibitors and mTOR inhibitors respectively. The higher expression of RAF1 mRNA and mTOR signaling pathway are not typical molecular alterations in patients with mRCC. RAF1 mRNA overexpression in metastatic site as well as activation of the alternative signaling pathway (RAS-RAF-MAPK in tumor cell are negative prognostic factors of the efficacy of targeted therapy. Activation of the signaling RAS-RAF-MAPK pathway in tumor cells is probably an alternative independent mechanism that “drives” tumor development in certain groups of patients.

    Full Text Available Abstract Background The aim of this study was to clarify the clinical significance of TM4SF members CD9, CD63 and CD82 in human gastric carcinoma. Methods By employing RT-PCR and immunohistochemistry, we studied the expression of CD9, CD63 and CD82 in 49 paired tissue specimens of normal gastric mucosa and carcinoma. All tissues were obtained from patients who underwent curative surgery. Results All normal gastric epithelium and gastric ulcer tissues strongly expressed transcripts and proteins of CD9, CD63 and CD82 as compared with corresponding controls. We found a significant correlation between CD63 mRNA level and different pM statuses (P = 0.036. Carcinomas in M0 stage revealed a stronger expression of CD63 than carcinomas in M1 stage. Expression of CD9 protein was found significantly stronger in pN0, pM0 than in advanced pN stages (P = 0.03, pM1 (P = 0.013, respectively. We found the relationship between CD63 expression, gender (p = 0.09 and nodal status (p = 0.028, respectively. Additionally, advanced and metastasized tumor tissues revealed significantly down-regulated CD82 protein expression (p = 0.033 and p = 0, respectively, which correlated with the tumor pTNM stage (p = 0.001. Conclusion The reduction of CD9, CD63 and CD82 expression are indicators for the metastatic potential of gastric carcinoma cells. Unlike their expression in other tumor types, the constitutive expression of CD63 may indicate that this factor does play a direct role in human gastric carcinogenesis.

    gland. At the time of diagnosis, patients present lymph node and lung metastasis. It affects mainly young women. This case report describes a cardiac tamponade as the initial manifestation of an unusual variant of papillary thyroid carcinoma. A 32 year-old woman was attended at the emergency room with epigastric pain and dry cough. Physical examination revealed hypotension, tachycardia and decreased heart sounds. An echocardiogram confirmed severe pericardial effusion. Pericardial fluid cytology was positive for malignancy. The patient evolved with recurrent pericardial effusion and a pleuropericardial window was performed. At this procedure, a subpleural nodular lesion was found, which histology corresponded to metastases of papillary carcinoma, probably from thyroid origin. Total thyroidectomy was performed. The final diagnosis was papillary carcinoma, diffuse sclerosing variant. This variant infiltrates the connective tissue of the interfollicular spaces, mimicking thyroiditis and it is associated with early vascular permeation. This tumor, compared to the classic variants of thyroid carcinoma, is more aggressive and it has higher risk of recurrence. Papillary thyroid carcinoma should be considered as differential diagnosis in our population, in all metastatic papillary lesions, and even more in young female patients.
