    Merkel cell carcinoma is an uncommon neuroendocrine carcinoma with a rising incidence and an aggressive behavior. It predominantly occurs in older patients, with onset occurring at a mean age of 75-80 years. Recognized risk factors are ultraviolet sunlight exposure, immunosuppression, and, more recently, Merkel cell polyomavirus. We report a case of Merkel cell carcinoma in a young HIV positive patient with Merkel Cell polyomavirus detected in the tumor.

    Although emerging evidence demonstrates increased circulating endothelial progenitor cells in patients with solid tumors, to our knowledge it is still unknown whether such cells can be cultured from patients with highly angiogenic renal cell carcinoma. We cultured and characterized circulating endothelial progenitor cells from patients with renal cell carcinoma. The circulating endothelial progenitor cell level (percent of CD45(-)CD34(+) VEGF-R2(+) cells in total peripheral blood mononuclear cells) was quantified in 47 patients with renal cell carcinoma and 40 healthy controls. Peripheral blood mononuclear cells were then isolated from 33 patients with renal cell carcinoma and 30 healthy controls to culture and characterize circulating endothelial progenitor cells. The circulating endothelial progenitor cell level was significantly higher in patients with renal cell carcinoma than in healthy controls (0.276% vs 0.086%, p cells first emerged significantly earlier in patient than in control preparations (6.72 vs 14.67 days, p culture success rate (87.8% vs 40.0% of participants) and the number of colonies (10.06 vs 1.83) were significantly greater for patients than for controls (each p cell level correlated positively with the number of patient colonies (r = 0.762, p Cells cultured from patients and controls showed a similar growth pattern, immunophenotype, ability to uptake Ac-LDL and bind lectin, and form capillary tubes in vitro. However, significantly more VEGF-R2(+) circulating endothelial progenitor cells were found in preparations from patients with renal cell carcinoma than from healthy controls (21.1% vs 13.4%, p cell colonies, a higher cell culture success rate and more colonies were found for patients with renal cell carcinoma than for healthy controls. Results indicate the important significance of VEGF-R2(+) circulating endothelial progenitors in patients with renal cell carcinoma.

    Basal cell carcinoma of the axilla, an area that is not usually exposed to the sun, is rare. Individuals with basal cell nevus syndrome, a disorder associated with a mutation in the patch 1 (PTCH1) gene, develop numerous basal cell carcinomas. To describe a woman with basal cell nevus syndrome who developed a pigmented basal cell carcinoma in each of her axilla and to review the features of axillary basal cell carcinoma patients with Goltz-Gorlin syndrome. Pubmed was used to search the following terms: axillary basal cell carcinoma and basal cell nevus syndrome. The papers and their citations were evaluated. Basal cell nevus syndrome patients with basal cell carcinoma of the axilla were observed in two women; this represents 2.5% (2 of 79) of the patients with axillary basal cell carcinoma. Both women had pigmented tumors that were histologically nonaggressive. The cancers did not recur after curettage or excision. Basal cell carcinoma of the axilla has only been described in 79 individuals; two of the patients were women with pigmented tumors who had basal cell nevus syndrome. Similar to other patients with axillary basal cell carcinoma, the tumors were histologically nonaggressive and did not recur following treatment. Whether PTCH1 gene mutation predisposes basal cell nevus patients to develop axillary basal cell carcinomas remains to be determined.

    Gorlin syndrome (Naevoid Basal Cell Carcinoma Syndrome) is a rare autosomal dominant syndrome caused by mutations in the PTCH gene with a birth incidence of approximately 1 in 19,000. Patients develop multiple basal cell carcinomas of the skin frequently in early life and also have a predisposition to additional malignancies such as medulloblastoma. Gorlin Syndrome patients also have developmental defects such as bifid ribs and other complications such as jaw keratocysts. We studied the incidence and frequency of basal cell carcinomas in 202 Gorlin syndrome patients from 62 families and compared this to their gender and mutation type. Our data suggests that the incidence of basal cell carcinomas is equal between males and females and the mutation type cannot be used to predict disease burden

    The aim of this study is to measure and compare the dynamic thiol/disulphide homeostasis of patients with basal cell carcinoma and healthy subjects with a newly developed and original method. Thirty four patients attending our outpatient clinic and clinically and histopathologically diagnosed as nodular basal cell carcinoma, and age and gender matched 30 healthy individuals have been involved in the study. Thiol/disulphide homeostasis tests have been measured with a novel automatic spectrophotometric method developed and the results have been compared statistically. Serum native thiol and disulphide levels in the patient and control group show a considerable variance statistically (p = 0.028, 0.039, respectively). Total thiol levels do not reveal a considerable variation (p = 0.094). Disulphide/native thiol ratios and native thiol/total thiol ratios also show a considerable variance statistically (p = 0.012, 0.013, 0.010, respectively). Thiol disulphide homeostasis in patients with basal cell carcinoma alters in the way that disulphide gets lower and thiols get higher. Thiol/disulphide level is likely to have a role in basal cell carcinoma pathogenesis.

    Full Text Available We report a case of primary small-cell carcinoma of the stomach in a 75-year-old man. The patient was admitted to our hospital with a 1-week history of intermittent tarry stool. An upper gastrointestinal examination revealed a large stage A2 ulcer in the greater curvature of the body of the stomach, and pathological findings from biopsy specimens revealed small-cell carcinoma. The tumor cells were small-sized, composed of hyperchromatic nuclei with scant cytoplasm, and stained positive for cytokeratin, synaptophysin, and chromogranin A. The patient was diagnosed with primary small-cell carcinoma of the stomach. He declined further evaluation and received palliative management. This is a rare carcinoma of the stomach, with aggressive manifestations and a poor prognosis. The mean survival of patients with primary gastric small-cell carcinoma is reported to be 7 months. The choice of treatment for this disease is still controversial. This rare gastric tumor should be listed in the differential diagnosis of gastric carcinoma in the elderly.

    Skin squamous cell carcinomas (SCCs) are arguably the second most common carcinoma of the skin and are responsible for the majority of non-melanoma skin cancer deaths. Gynecologist treated a Caucasian 56-years old female patient for genital wart with podophyllotoxin cream. She did not achieve complete response and therefore she has interrupted the therapy and the collaboration with the gynecologist. At the time of evaluation the lesion had a size of man's palm in anogenital region and showed characteristic features of neoplasm. The regional lymph nodes have produced infiltrated painful bubo. PCR analysis for HPV proved negative. Histopathology revealed well-differentiated squamous cell keratinizing carcinoma from the tumor as well as from the regional lymph node packet. Staging computed tomography scans proved negative and pelvis scans disclosed regional lymphadenopathy underlying the tumor. Palliative radiation therapy (by linear accelerator) was administered for the oversized tumor to the total TD 50.0Gy. The patient died 6 months after diagnostic assessment from cardio-respiratory failure. Staging computed tomography before her death did not disclose distinct metastases in her inner organs. Well-differentiated squamous cell keratinizing carcinoma could be growing endophytically affecting the underlying adipose tissue and musculature, with spreading into the regional lymph nodes. The rate of metastases into inner organs seems to vary according to the aggressiveness and metastatic behavior of each SCC. The case report calls for attention to the importance of collaboration among various specialists assisting in the diagnosis and management of skin neoplasm (Fig. 5, Ref. 12).

    To investigate the change of serum prolactin (PRL) level in patients with oral cavity squamous cell carcinoma, serum PRL level in 79 normal person and 68 cases of patient s was measured by RIA. The result showed that serum PRL level was significantly higher in 26 patients (38.2%, 26/68) than that in the control (P 0.05) between the sex and region of lesion. The above results indicated that proportion of patient with oral cavity squamous cell carcinoma was hyperprolactinaemia and the change of PRL was related to the development in oral cavity squamous cell carcinoma.

    The carcinoma at Merkel cells is a rare and aggressive skin cancer, principally of the aged adult. The surgery is the fundamental treatment. The interest of the adjuvant radiotherapy is discussed for the aged patient. In the limits of this retrospective analysis, the postoperative radiotherapy appeared to bring a similar benefit as for younger patients. (N.C.)

    Full Text Available Primary renal cell carcinomas have rarely been reported in patients with crossed fused renal ectopia. We presented a patient with right to left crossed fused kidney harbouring renal tumor. The most frequent tumor encountered in crossed fused renal ectopia is renal cell carcinoma. In this case, partial nephrectomy was performed which pave way to preservation of the uninvolved both renal units. Due to unpredictable anatomy, careful preoperative planning and meticulous delineation of renal vasculature is essential for preservation of the uninvolved renal units.

    To assess the combined effectiveness of angioinfarction and immunotherapy for improving survival in patients with stage IV renal cell carcinoma. During the past 3 years, 13 patients of stage IV renal cell carcinoma were treated with angioinfarction and immunotherapy. Angioinfarction was performed on these 13 patients using absolute ethanol and occlusive balloon catheter. After angioinfarction, Interferon alpha was used for immunotherapy. For our analysis, 12 control patients of stage IV renal cell carcinoma without treatment were included in the study. Survival has been calculated according to the Kaplan and Meier method. The 1 year survival rate and median survival time in patients treated with angioinfarction and immunotherapy, were 46% and 13 months and in patients without treatment, 16% and 4 months, respectively. The combined treatment of angioinfarction and immunotherapy is of considerable value for improving survival in patients with stage IV renal cell carcinoma

  15. Treatment recommendations in patients diagnosed with high-risk cutaneous squamous cell carcinoma

    Non-melanoma cutaneous cancers occur at an epidemic rate in Australia. With an ageing population, more Australians will develop these cancers and at an increasing rate. In the majority of cases local treatment is highly curative. However, a subset of the population will be diagnosed with a high-risk cutaneous squamous cell carcinoma. These can be defined as patients at risk of having subclinical metastases to regional lymph nodes based on unfavourable primary lesion features (including inadequately excised and recurrent lesions), patients with metastatic squamous cell carcinoma to regional lymph nodes, and squamous cell carcinoma in immunosuppressed patients. The mortality and morbidity associated with high-risk cutaneous squamous cell carcinoma is usually as a consequence of uncontrolled metastatic nodal disease and, to a lesser extent, distant metastases. Radiotherapy has an essential role in treating these patients and in many cases the addition of adjuvant radiotherapy may be life saving. It is therefore important that all clinicians treating skin cancers have an understanding and awareness of the optimal approach to these patients. The aim of this article is to present treatment recommendations based on an overview of the current published literature. Copyright (2005) Blackwell Science Pty Ltd

    Sentinel lymph node biopsy is used to stage Merkel cell carcinoma, but its prognostic value has been questioned. Furthermore, predictors of outcome in sentinel lymph node positive Merkel cell carcinoma patients are poorly defined. In breast carcinoma, isolated immunohistochemically positive tumor cells have no impact, but in melanoma they are considered significant. The significance of sentinel lymph node metastasis tumor burden (including isolated tumor cells) and pattern of involvement in Merkel cell carcinoma are unknown. In this study, 64 Merkel cell carcinomas involving sentinel lymph nodes and corresponding immunohistochemical stains were reviewed and clinicopathological predictors of outcome were sought. Five metastatic patterns were identified: (1) sheet-like (n=38, 59%); (2) non-solid parafollicular (n=4, 6%); (3) sinusoidal, (n=11, 17%); (4) perivascular hilar (n=1, 2%); and (5) rare scattered parenchymal cells (n=10, 16%). At the time of follow-up, 30/63 (48%) patients had died with 21 (33%) attributable to Merkel cell carcinoma. Patients with pattern 1 metastases had poorer overall survival compared with patients with patterns 2-5 metastases (P=0.03), with 22/30 (73%) deaths occurring in pattern 1 patients. Three (10%) deaths occurred in patients showing pattern 5, all of whom were immunosuppressed. Four (13%) deaths occurred in pattern 3 patients and 1 (3%) death occurred in a pattern 2 patient. In multivariable analysis, the number of positive sentinel lymph nodes (1 or 2 versus >2, PMerkel cell carcinoma, the pattern of sentinel lymph node involvement provides important prognostic information and utilizing this data with other clinicopathological features facilitates risk stratification of Merkel cell carcinoma patients who may have management implications.

    Full Text Available Merkel cell carcinoma (MCC is a rare cutaneous tumor arising from neuroendocrine cells and Merkel cells. Early diagnosis and treatment is important because of its aggressive course. We here report a 61 years old man with chronic renal failure, 3x5 cm mass on his right leg and inguinal-paraaortic lymph node metastases and resulting in death. MCC in the literature of the AIDS disease, organ transplantation, immunosuppressive therapy areas, and additional malignancies (multiple myeloma, chronic lymphocytic leukemia, non-Hodgkin's lymphoma, and melanoma have been reported in patients with increased incidence. Up to date a patient with renal transplantation and Merkel cell carcinoma have been reported in the literature, Merkel cell carcinoma with chronic renal failure have not been reported.

  18. Oat cell carcinoma of esophagus: a report of six British patients with a review of the literature

    1984-01-01

    This paper presents 6 British patients with a diagnosis of oat cell carcinoma of the esophagus. Sixty-six patients have previously been reported in the literature, the majority (30) being British. Approximately two-thirds of these tumors have been reported as pure oat cell carcinoma of the esophagus. Four other histological patterns have been described: oat cell carcinoma with squamous carcinoma in situ; oat cell carcinoma with squamous carcinoma; oat cell carcinoma with adenocarcinoma; and oat cell carcinoma with carcinoid differentiation. A preponderance of males has also been noted, although this series shows a 2:1 female:male ratio. The tumor arises most commonly in the mid or lower esophagus. The cell of origin of these tumors is considered to be the Kulchitsky or APUD cell of neuroectodermal derivation. They may show neurosecretory granules on electron microsopy. Polypeptides have been identified within the tumor cells. One previous report describes a patient with primary oat cell carcinoma of the esophagus and hypercalcemia. A patient with the syndrome of inappropriate anti-diuretic hormone secretion is described in this paper. Survival is poor following radiotherapy, with a median survival of 3 months in this series. On reviewing the records of the Radiation Oncology Unit in Edinburgh, no patient with oat cell carcinoma of the esophagus was reported before 1972. This suggests that awareness of this tumor is increasing and, although rare, its incidence is greater than previously reported

    Extrapulmonary small-cell carcinoma (EPSCC) is a rare disease. Management is based on small-cell lung carcinoma. Prophylactic cranial irradiation (PCI) is not routinely administered in EPSCC. This study investigates the role of PCI in EPSCC, by analyzing the incidence, treatment, and survival of patients with brain metastases in a national cohort. Disease biology and epidemiology are also investigated.

    Patients with esophageal squamous cell carcinoma have poor survival and high recurrence rate, thus an effective prognostic biomarker is needed. Endothelin-converting enzyme-1 is responsible for biosynthesis of endothelin-1, which promotes growth and invasion of human cancers. The role of endothelin-converting enzyme-1 in esophageal squamous cell carcinoma is still unknown. Therefore, this study investigated the significance of endothelin-converting enzyme-1 expression in esophageal squamous cell carcinoma clinically. We enrolled patients with esophageal squamous cell carcinoma who provided pretreated tumor tissues. Tumor endothelin-converting enzyme-1 expression was evaluated by immunohistochemistry and was defined as either low or high expression. Then we evaluated whether tumor endothelin-converting enzyme-1 expression had any association with clinicopathological findings or predicted survival of patients with esophageal squamous cell carcinoma. Overall, 54 of 99 patients with esophageal squamous cell carcinoma had high tumor endothelin-converting enzyme-1 expression, which was significantly associated with lymph node metastasis ( p = 0.04). In addition, tumor endothelin-converting enzyme-1 expression independently predicted survival of patients with esophageal squamous cell carcinoma, and the 5-year survival was poorer in patients with high tumor endothelin-converting enzyme-1 expression ( p = 0.016). Among patients with locally advanced and potentially resectable esophageal squamous cell carcinoma (stage II and III), 5-year survival was poorer with high tumor endothelin-converting enzyme-1 expression ( p = 0.003). High tumor endothelin-converting enzyme-1 expression also significantly predicted poorer survival of patients in this population. In patients with esophageal squamous cell carcinoma, high tumor endothelin-converting enzyme-1 expression might indicate high tumor invasive property. Therefore, tumor endothelin-converting enzyme-1 expression

  1. Red Dot Basal Cell Carcinoma: Report of Cases and Review of This Unique Presentation of Basal Cell Carcinoma.

    2017-03-22

    Red dot basal cell carcinoma is a unique variant of basal cell carcinoma. Including the three patients described in this report, red dot basal cell carcinoma has only been described in seven individuals. This paper describes the features of two males and one female with red dot basal cell carcinoma and reviews the characteristics of other patients with this clinical subtype of basal cell carcinoma. A 70-year-old male developed a pearly-colored papule with a red dot in the center on his nasal tip. A 71-year-old male developed a red dot surrounded by a flesh-colored papule on his left nostril. Lastly, a 74-year-old female developed a red dot within an area of erythema on her left mid back. Biopsy of the lesions all showed nodular and/or superficial basal cell carcinoma. Correlation of the clinical presentation and pathology established the diagnosis of red dot basal cell carcinoma. The tumors were treated by excision using the Mohs surgical technique. Pubmed was searched with the keyword: basal, cell, cancer, carcinoma, dot, red, and skin. The papers generated by the search and their references were reviewed. Red dot basal cell carcinoma has been described in three females and two males; the gender was not reported in two patients. The tumor was located on the nose (five patients), back (one patient) and thigh (one patient). Cancer presented as a solitary small red macule or papule; often, the carcinoma was surrounded by erythema or a flesh-colored papule. Although basal cell carcinomas usually do not blanch after a glass microscope slide is pressed against them, the red dot basal cell carcinoma blanched after diascopy in two of the patients, resulting in a delay of diagnosis in one of these individuals. Dermoscopy may be a useful non-invasive modality for evaluating skin lesions when the diagnosis of red dot basal cell carcinoma is considered. Mohs surgery is the treatment of choice; in some of the patients, the ratio of the area of the postoperative wound to that

    The uv-induced DNA repair synthesis in peripheral leukocytes from 7 patients with the nevoid basal cell carcinoma syndrome was compared to that in peripheral leukocytes from 5 patients with basal cell carcinomas and 39 healthy subjects. A dose response curve was established for each individual, and maximum DNA repair synthesis was used as a measure of the capacity for DNA repair. The patients with the nevoid basal cell carcinoma syndrome had about 25% lower level of maximum DNA repair synthesis as compared to the patients with basal cell carcinomas and control individuals. The possibility that DNA repair mechanisms may be involved in the etiology to the nevoid basal cell carcinoma syndrome is discussed

    This study investigated the expression of wingless-type inhibitory factor-1 (WIF-1) and Ihh protein in tumor tissues and their clinical significance in patients with lung squamous cell carcinoma and adenocarcinoma. The expression of WIF-1 and Ihh protein in 74 squamous cell carcinomas and 76 adenocarcinomas was measured by immunohistochemistry. The percentage of positive WIF-1 protein expression was significantly higher, while positive Ihh protein expression was significantly lower in patients with well-differentiated lung squamous cell carcinoma and adenocarcinoma, tumor node metastasis (TNM) stage I disease, and lymph node metastasis than that in patients with poorly differentiated tumor, TNM stage III disease, and lymph node metastasis (PIhh protein expression survived significantly shorter than patients with negative Ihh protein expression. In contrast, no significant difference in mean survival was observed in patients with lung squamous cell carcinoma and adenocarcinoma with positive and negative WIF-1 protein expression (P>0.05). Ihh is a marker for poor prognosis in patients with lung squamous cell carcinoma and adenocarcinoma. WIF-1 is not a predictive marker for lung cancer.

    Purpose: An increased incidence of renal tumors has been observed in patients with end-stage-renal-disease (ESRD). The very strong association with acquired renal cystic disease (ACRD) and increased incidence of the renal tumors (conventional renal cell carcinoma (CRCC), papillary renal cell carcinoma (PRCC) or papillary renal cell adenoma (PRCA)) was reported. This study discusses the role of computed tomography (CT) in detecting renal tumors in patients with renal impairment: pre-dialysis, those receiving dialysis or with renal allograft transplants. Materials and methods: Ten patients (nine male, one female) with renal cell tumors were enrolled into a retrospective study; two were new dialysis patients, three on long-term dialysis, and five were renal transplant recipients with history of dialysis. All patients underwent helical CT, a total of 11 procedures were performed. Sixteen-row detector system was used five times, and a 64-row detector system for the six examinations. All patients underwent nephrectomy of kidney with suspected tumor, 15 nephrectomies were performed, and 1 kidney was assessed during autopsy. CT findings were compared with macroscopic and microscopic assessments of the kidney specimen in 16 cases. Results: Very advanced renal parenchyma atrophy with small cysts corresponding to ESRD was found in nine patients, chronic pyelonephritis in remained one. A spontaneously ruptured tumor was detected incidentally in one case, patient died 2 years later. In the present study, 6.25% (1/16) were multiple PRCA, 12.5% (2/16) were solitary PRCC, 12.5% tumors (2/16) were solitary conventional renal cell carcinomas (CRCC's), 12.5% tumors (2/16) were multiple conventional renal cell carcinomas (CRCC's), 25% (4/16) were CRCC's combined with multiple papillary renal cell carcinomas with adenomas (PRCC's and PRCA's), and 25% (4/16) of the tumors were multiple PRCC's combined with PRCA's without coexisting CRCC's. Bilateral renal tumors were found in our study

    1985-01-01

    The diagnosis of basosquamous cell carcinoma is controversial. A review of cases of basal cell carcinoma showed 23 cases that had conspicuous areas of squamous cell carcinoma. This was distinguished from squamous differentiation and keratotic basal cell carcinoma by a comparative study of 40 cases of compact lobular and 40 cases of keratotic basal cell carcinoma. Areas of intermediate tumour differentiation between basal cell and squamous cell carcinoma were found. Basal cell carcinomas with ...

    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.

    Full Text Available Squamous cell carcinoma antigen recognized by T cells 3 (SART3, a tumor-associated antigen expressed in many cancers, functions in tumor rejection. In this study, we investigated its usefulness as an immunotherapeutic target in hepatocellular carcinoma (HCC.The expression of SART3 in hepatoma cell lines and HCC tissues was investigated by immunofluorescence and immunohistochemical analyses. Two peptides derived from SART3 (SART3109 and SART3315 were used for immunological analysis. T-cell responses were investigated by interferon-gamma (IFN-γ enzyme-linked immunospot and cytotoxic T lymphocyte (CTL assays using peripheral blood mononuclear cells (PBMCs in 47 patients, and tumor-infiltrating lymphocytes in 8 of 47 patients with HCC. The safety of immunotherapy using a SART3-derived peptide was investigated by vaccinations of SART3109 in 12 patients with HCC (trial registration: UMIN000005677.The immunofluorescence and immunohistochemical analyses showed that SART3 was expressed in six HCC cell lines, and in HCC tissues including of alpha-fetoprotein-negative individuals. SART3-specific CTLs were generated by stimulating PBMCs with the peptides, and they showed cytotoxicity against HCC cells expressing the protein. Of the 47 HCC patients, 25.5% and 10.6% showed significant responses to SART3109 and SART3315, respectively. The infiltration of SART3109-specific IFN-γ-producing CTLs into the tumor site was confirmed. In the vaccination study, no severe adverse events were observed, and the peptide-specific CTLs were newly induced in four of five patients tested.SART3 is an immunotherapeutic candidate, and peptides from this antigen may be applied in HCC immunotherapy.UMIN000005677.

    Both small cell carcinoma and sarcomatoid carcinoma of the urinary bladder are highly aggressive tumors, and a concurrence of these tumors is extremely rare. We report a case of urinary bladder cancer with small cell carcinoma as a predominant component, accompanied by sarcomatoid carcinoma and conventional urothelial carcinoma (UC). Although the small cell carcinoma component had resolved on receiving chemoradiotherapy, rapid growth of the residual tumor led to a fatal outcome. A 47-year-old man presented with occasional bladder irritation and had a 2-year history of asymptomatic hematuria. Cystoscopy revealed a huge mass in the urinary bladder, and transurethral resection was performed. Microscopically, small cell carcinoma was detected as the major tumor component. Spindle-shaped sarcomatoid cells were also observed that were intermingled with small cell carcinoma and conventional UC. In addition, a sheet-like growth of the lipoblast-like neoplastic cells was observed focally. Initially, by providing chemoradiotherapy, we achieved a marked tumor regression; however, the tumor rapidly regrew after the completion of chemoradiotherapy, and the patient underwent radical cystectomy. Only conventional UC and sarcomatoid carcinoma were identified in the cystectomy specimen. The patient died of the disease 4 months after cystectomy. Urinary bladder cancer may include a combination of multiple aggressive histologies as in the present case. Because the variation in the tumor components may affect the efficacy of therapy, a correct diagnosis of every tumor component is necessary. Copyright © 2016 Elsevier GmbH. All rights reserved.

    2006-01-01

    PURPOSE: The aim of this study was to investigate symptoms of depression and anxiety in the patients with oral squamous cell carcinoma (OSCC). METHODS: 76 patients with oral squamous cell carcinoma participated in this program. All patients were rated with the self-rating anxiety scale (SAS) and the self-rating depression scale (SDS). The mean scores of SAS and SDS were compared to those scores of the Norm of Chinese people. In addition, the different treatment results of the patients with different levels of anxiety and depression were studied. Further, the number of patients of SAS, SDS with more than 50 score were compared between primary cancer patients and recurrent cancer patients. RESULTS: The scores of SAS, SDS and the number of patients with more than 50 score in the patients group were obviously higher than those in Chinese Norm (P<0.01).The levels of anxiety and depression in 32 patients with recurrent cancer were more severe than those of 44 patients with primary cancer. The patients with anxiety and/or depression showed poor prognosis. CONCLUSION: Anxiety and depression are common symptoms in patients with OSCC and have negative effects on the prognosis, thus the psychological intervention for the patients must be carried out.

    This study aims to investigate the effects of treatments on the quality of life for patients with esophageal squamous cell carcinoma patients diagnosed at early and late stages. From a medical center in central Taiwan, patients who had been diagnosed with esophageal squamous cell carcinoma from February 2007 and March 2011 were recruited. Using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) and the Quality of Life Questionnaire Oesophageal 18 (QLQ-OES18), quality of life scores for 105 esophageal squamous cell carcinoma patients were obtained and assessed. Multivariate analysis was performed on the quality of life scores after stratification by cancer stage. Among early-stage esophageal squamous cell carcinoma patients, those received only surgery (S-only) performed better in physical and social functioning compared with patients who underwent surgery and concurrent chemoradiotherapy (S+CCRT) (β = 9.0, P = 0.03; β = 12.1, P = 0.04, respectively). For those that received only concurrent chemoradiotherapy (CCRT-only), they performed worse in role and emotional functioning relative to S+CCRT patients (β = -17.2, P = 0.02; β = -15.7, P = 0.05, respectively). Among late-stage patients, CCRT-only treatment gave insignificantly better global health status and functional scale scores and less severe symptoms compared to the S+CCRT option. Better functional scores and less aggravated symptoms are observed in early-stage esophageal squamous cell carcinoma patients who received surgery-only treatment relative to those that underwent both surgery and chemoradiotherapy. For late-stage esophageal cancer patients, the measured difference of quality of life is not significant between CCRT-only and S+CCRT treatments. © The Authors 2017.

    Merkel cell carcinoma (MCC) is a rare and aggressive cutaneous malignancy. The infectivity of Merkel cell polyomavirus (MCPyV), an apparent agent in MCC development, may be exacerbated with impaired immune responses. This paper reviews relevant data regarding the role of immunosuppression in the development of MCC and describes modes of immunodeficient states. Because of the inherently low incidence rate of MCC, several case studies and series are also briefly mentioned to provide a more comprehensive summary of MCC in the setting of immunosuppression. We describe immunosuppressed patients who have experienced excessive UV radiation, organ transplantation, human immunodeficiency virus infection/AIDS, autoimmune diseases, and lymphoproliferative disorders. Iatrogenic forms of immunosuppression are also highlighted. Studies that quantify risks consistently report that individuals with a history of solid organ transplantation, autoimmune diseases, AIDS, and/or lymphoproliferative diseases have a significantly elevated risk of developing MCC. Overall, immunocompromised patients also appear to have an early onset and more aggressive course of MCC, with poorer outcomes. Recommendations for multidisciplinary approaches are proposed to effectively prevent and manage MCC in these patients.

    Xeroderma pigmentosum is a rare autosomal-recessive disorder that appears in early childhood. Squamous cell carcinoma is not uncommon in patients with xeroderma pigmentosum and mostly involving the face, head, neck, and scalp. However, squamous cell carcinoma of the scalp may exhibit an aggressive course. Here, we present a huge squamous cell carcinoma of the scalp in a three-years-old child with xeroderma pigmentosum. In addition, we illustrate the challenges of a child with xeroderma pigmentosum who grows up in a sunny environment where the possibility of early onset of squamous cell carcinoma is extremely high in any suspected skin lesion. In xeroderma pigmentosum patients, squamous cell carcinoma of the scalp can present early and tends to be unusually aggressive. In sunny areas, proper education to the patient and their parents about ultra-violet light protection and early recognition of any suspicious lesion could be life-saving.

    Sixty patients with squamous cell carcinoma of the oropharynx treated at our hospital from 1991 through 1999 were analyzed. In terms of curative treatments, definitive radiotherapy or curative surgery after neoajuvant chemotherapy had been mainly applied for advanced cases until 1997. Since 1998, advanced cases have been treated with concomitant chemoradiotherapy. The cause-specific survival rate at 5 years for the 60 patients was 50% (stage I, II, 100%; III, 45%; IV A, 36%; IV B, 0%). In the 35 patients with operable advanced-stage disease, the 5-year cause-specific survival rate was 35% in cases treated with definitive radiotherapy, and 66% in those treated with curative surgery, respectively. All 12 operable patients treated with concomitant chemoradiotherapy showed complete response, and 10 patients in this group are disease-free now. However, many problems in definitive treatment modalities, including concomitant chemoradiotherapy for advanced cases with oropharyngeal carcinoma, have not been clarified yet. (author)

    This study was to evaluate the prognostic significance of serum lipids in esophageal squamous cell carcinoma patients who underwent esophagectomy. Preoperative serum lipids were collected from 214 patients who were diagnosed with esophageal squamous cell carcinoma. All of the patients received esophagectomy in Qilu Hospital of Shandong University from January 2007 to December 2008. The records and data were analyzed retrospectively. We found that low total cholesterol (for T stage, p = 0.006; for TNM stage, p = 0.039) and low-density lipoprotein cholesterol (for T stage, p = 0.031; for TNM stage, p = 0.035) were associated with advanced T stage and TNM stage. Kaplan-Meier survival analysis indicated that low total cholesterol and low-density lipoprotein cholesterol were associated with shorter disease-free survival(for total cholesterol, p = 0.045; for low-density lipoprotein cholesterol, p squamous cell carcinoma patients who underwent esophagectomy. LHR can serve as a promising serum lipids-based prognostic indicator.

    Merkel cell carcinoma (MCC) is a rare, very aggressive tumour. The pathogenesis remains unclear, but UV radiation, immunosuppression, and the presence of Merkel cell polyomavirus in the tumour genome appear to have a key role. Merkel cell carcinoma is a highly aggressive tumour that often has a lethal end. A patient at 93 years of age comes for an examination by a dermatologist due to a rapidly growing nodular tumour growth in the forehead area. A tumour was about 3 cm in size. It had no signs of basal-cell carcinoma, no arborising vascularisation, no pigmentations on dermoscopy. Clinically, an eventual Merkel cell carcinoma was considered for the patient, but other primary skin tumours had to be excluded, as well as the possibility that regarding the patient's age, it may be a metastatic deposit. A skin biopsy was performed, as well as H-E examination and immunohistochemical analyses (positive CD56, positivity of neuroendocrine markers synaptophysin, chromogranin) which were in favour of Merkel cell carcinoma of the skin. After setting the diagnosis, our patient was treated with therapy which led to a complete withdrawal of a tumour. However, after 3 months the patient had repeated relapse of a tumour at the same site on the forehead and metastases in the retroauricular lymph nodes bilaterally. It shows that the radiotherapy as monotherapy has a great effect on the removal of the tumour formation, but unfortunately, it has no impact on lesion recurrence. It is also compatible with the literature data. In many adult patients, as our case suggests, radiotherapy could be a good palliative treatment opportunity that should be considered, as well as a combination of radiation therapy with other oncologic therapeutic options.

    The diagnosis value of a new tumor marker, CYFRA 21-1, was studied in the blood samples collected from 22 controls, and 87 pre-treatment patients with squamous cell carcinoma of the cervix. Sensitivity and specificity of CYFRA 21-1 was was compared with those of squamous cell carcinoma antigen (SCC) measured in the sera of the same patients. Serum CYFRA 21-1 levels were higher in patients with squamous cell carcinoma than in controls (p < 0.05), and correlated with FIGO stage (Stage IIb-IV vs. Stage Ib-IIa, p = 0.0477). Using 2.5 ng/ml as cut-off value, elevated CYFRA 21-1 levels were found in 13.6% of controls, 34.8% of patients with Stage Ib-IIa squamous cell carcinoma of the cervix, and 63.5% of patients with Stage IIb-IV squamous cell carcinoma of the cervix. However, there was less sensitivity and specificity of CYFRA 21-1 than those of SCC in detecting squamous cell carcinoma of the cervix. CYFRA 21-1 may not be a better tumor marker than SCC for squamous cell carcinoma of the cervix. (author)

    Serum glycoproteins were evaluated in oral squamous cell carcinoma patients treated with radiotherapy and also the effect of vitamin E was studied. Cell surface glycoconjugates are important parameters in the detection of malignancy. Thus, the objective of the present study is to evaluate the efficacy of vitamin E on glycoproteins in oral cavity cancer patients treated with radiotherapy. The study includes 26 age and sex matched normal healthy individuals and 26 patients with squamous cell carcinoma of oral cavity. These patients were divided into two groups, one for radiotherapy alone (at a dosage of 6000 cGy in five fractions per week for a period of six weeks) and the other for radiotherapy plus vitamin E supplementation (at a dosage of 400 IU/day of vitamin E) for the entire period of radiotherapy. Levels of hexose, hexosamine, fucose and sialic acid were increased in oral squamous cell carcinoma patients and a significant decrease was observed in radiation treated patients when compared to control. The levels of glycoconjugates were significantly decreased in radiation treated patients supplemented with vitamin E. This measurement may be useful in assessing disease progression and identifying patients resistant to therapy and a possible role of vitamin E on reduction in glycoconjugate levels of radiation treated oral squamous cell carcinoma patients.

    The authors studied seven patients with gingival carcinoma attended at the Head and Neck Surgery and Otorrhinolaryngology Service and the Diagnostic Imaging Service of 'Complexo Hospitalar Heliopolis', Sao Paulo, SP, Brazil, between 1985 and 1996. Squamous cell type carcinomas were identified in all cases. All patients were male (100%) aged 48-72 years. Computed tomography was performed in six patients (85.6%). Four patients (57.1%) had not received any treatment before imaging examination whereas three patients (42.8%) had already been submitted to surgery or radiotherapy. The authors analyzed the primary site of the tumor and its extension to the mandible (5/7 cases; 71.4%), the floor of the mouth (3/7 cases; 42.8%), the floor of the maxillary sinus (1/7 cases; 14.2%) and the retromolar trigonum (1/7 cases; 14.2%). Metastatic lymph nodes were observed in five patients (71.4%). Diagnosis was confirmed by biopsy and histopathological examination in all cases. Comparison with surgical findings was possible in five cases (71.4%). (author)

    The purpose of this study was to investigate the clinical findings, treatment, and outcome of patients with glassy cell carcinoma of cervix. We reviewed all cases of glassy cell carcinoma of the uterine cervix confirmed and treated at the Dongsan Medical Center, Keimyung University, between January 1993 and December 2005. There were 7 cases with histopathologically confirmed gassy cell carcinoma. A tumor was diagnosed as glassy cell carcinoma if over 50% of the tumor cell type displayed glassy cell features. Six patients with stage IB had radical hysterectomy and bilateral pelvic node dissection, and 2 of them received adjuvant external pelvic irradiation with concurrent chemotherapy. Remaining one patient with stage IIA had curative concurrent chemoradiotherapy with external pelvic irradiation and brachytherapy. There were 7 patients diagnosed as glassy cell carcinoma among the 3,745 (0.2%) patients of carcinoma of uterine cervix. The mean age of 7 patients was 44 years with range of 35 to 53 years of age. The most frequent symptom was vaginal bleeding (86%). By the punch biopsy undertaken before treatment of 7 cases, 2 only cases could diagnose as glassy cell carcinoma of uterine cervix, but remaining of them confirmed by surgical pathological examination. The mean follow up duration was 73 months with range of 13 to 150 months. All 7 patients were alive without disease after treatment. Glassy cell carcinoma of the uterine cervix is a distinct clinicopathologic entity that demonstrates an aggressive biologic behavior. However for early-stage disease, we may have more favorable clinical outcome with radical surgery followed by chemoradiotherapy

    Full Text Available Background: Development of skin neoplasms is one of the most important chronic complications of radiation therapy. Basal cell carcinoma (BCC is the most frequent carcinoma occurring at the region of the body to which radiotherapy was delivered. Aim: The aim of this study was to evaluate clinical and histological aspects of basal cell carcinoma in patients with a history of radiotherapy. Materials and Methods: Medical records and microscopic slides of 80 patients with basal cell carcinoma who had received radiotherapy (1996-2006 were reviewed in pathology department of Imam Reza hospital of Mashhad, Iran. Collected data were analyzed statistically using descriptive test. Results: 60 men and 20 women were included, majority of them in their sixties. Plaque was the most common clinical pattern of basal cell carcinoma. Fifty one percent of the patients had pigmented and 42.5% had multiple lesions. Scalp was the most common site of involvement. Histologically, macronodular and pigmented carcinoma were the most predominant forms of basal cell carcinoma. Discussion: Majority of patients had scalp involvement and multiple lesions. Nodular and pigmented forms were the most common histological findings. We suggest the need for close supervision in patients with a history of radio therapy in the past.

    Purpose Merkel cell carcinoma carcinoma (M.C.C.) or primary cutaneous neuroendocrine carcinoma is a rare and aggressive malignancy affecting elderly. Optimal therapeutic strategy has not yet been established in elderly patients. Patients and methods From March 1996 to March 2007, 29 patients with Merkel cell carcinoma of were treated at the University Hospital of Amiens, France. Adjuvant radiotherapy (R.T.) was performed for 14 patients (50%) on the tumor bed with margins of 3 to 5 cm, an average dose of 46 Gy (30-60 Gy), by 2 Gy per fraction. Ten of them also received R.T. to the lymph node area at mean dose of 44.3 Gy (26-50 Gy). Duration of R.T. was 35 days. A retrospective analysis was conducted to better evaluate survival and prognostic factors. Results Median overall survival (O.S.) was 18.9 months (3-122) and the median time to progression (M.T.P.) 5.5 months (1-26). At 5 years, O.S. for irradiated patients was 47% (IC95: 12-82%) versus 27% (IC95: 5-49%) in cases of surgery alone (p = 0.032). The most frequent sites of recurrence were nodal (34.5%), local (24.1%) and metastatic (17.2%). For patients over 70 years, eight (36.5%) were free of disease at last news, 8 (36.5%) had died from cancer and six from other causes (27%). In this subgroup, M.T.P. was 6 months (2-19) and median O.S. of 19 months (4-87). There was no acute toxicity greater than grade 2. Conclusion Although limited by a retrospective analysis, this report suggests an advantage of postoperative R.T. for patients with M.C.C.. It combined low toxicity and improvement of survival. Prospective multicenter trials are needed to clarify and validate the optimal strategy. (authors)

    Lymph node metastasis with extranodal extension represents one of the most important adverse prognostic factors for survival in patients with head and neck squamous cell carcinoma. We propose that extranodal extension occurs to differing extents. The aim of this study was to determine the prognostic significance of extranodal extension in patients with head and neck squamous cell carcinoma. Two hundred and ninety-eight patients with head and neck squamous cell carcinoma who underwent surgical resection and neck dissection were included. Cervical lymph nodes were classified into four categories: (i) pathological N negative, (ii) extranodal extension negative, (iii) non-surgical extranodal extension and (iv) surgical extranodal extension. Lymph node metastases were detected in 67.1% of laryngeal/hypopharyngeal cancer patients and 52.7% of oral cancer patients. The 3-year disease-specific survival rates for patients in the pathological N negative, extranodal extension negative, non-surgical extranodal extension and surgical extranodal extension groups were 90.9%, 79.6%, 63.8% and 48.3%, respectively. In laryngeal/hypopharyngeal cancer patients, surgical extranodal extension was associated with a significantly poorer disease-specific survival than a pathological N negative, extranodal extension negative or non-surgical extranodal extension status. In oral cancer patients, no significant differences were observed between the non-surgical and surgical extranodal extension groups. However, non-surgical extranodal extension was associated with a poorer disease-specific survival than a pathological N negative or extranodal extension negative status. Surgical extranodal extension was a poor prognostic factor in patients with head and neck squamous cell carcinoma. The prognostic significance of surgical extranodal extension differed between laryngeal/hypopharyngeal and oral cancer patients. The clinical significance of surgical extranodal extension was much greater for

  13. Ultrastructural proof of polyomavirus in Merkel cell carcinoma tumour cells and its absence in small cell carcinoma of the lung.

    Directory of Open Access Journals (Sweden)

    Charlotte T A H Wetzels

    Full Text Available BACKGROUND: A new virus called the Merkel Cell Polyomavirus (MCPyV has recently been found in Merkel Cell Carcinoma (MCC. MCC is a rare aggressive small cell neuroendocrine carcinoma primarily derived from the skin, morphologically indistinguishable from small cell lung carcinoma (SCLC. So far the actual presence of the virus in MCC tumour cells on a morphological level has not been demonstrated, and the presence of MCPyV in other small cell neuroendocrine carcinomas has not been studied yet. METHODOLOGY/PRINCIPAL FINDINGS: We investigated MCC tissue samples from five patients and SCLCs from ten patients for the presence of MCPyV-DNA by PCR and sequencing. Electron microscopy was used to search ultrastructurally for morphological presence of the virus in MCPyV-DNA positive samples. MCPyV was detected in two out of five primary MCCs. In one MCC patient MCPyV-DNA was detected in the primary tumour as well as in the metastasis, strongly suggesting integration of MCPyV in the cellular DNA of the tumour in this patient. In the primary MCC of another patient viral particles in tumour cell nuclei and cytoplasm were identified by electron microscopy, indicating active viral replication in the tumour cells. In none of the SCLCs MCPyV-DNA was detected. CONCLUSIONS/SIGNIFICANCE: Our results strongly suggest that MCPyV is an oncogenic polyomavirus in humans, and is potentially causally related to the development of MCC but not to the morphological similar SCLC.

    Background: Circulating tumour cells (CTCs) can provide information on patient prognosis and treatment efficacy. However, there is no universal method to detect CTC currently available. Here, we compared the performance of two CTC detection systems based on the expression of the EpCAM antigen (CellSearch assay) or on cell size (ISET assay). Methods: Circulating tumour cells were enumerated in 60 patients with metastatic carcinomas of breast, prostate and lung origins using CellSearch according to the manufacturer's protocol and ISET by studying cytomorphology and immunolabelling with anti-cytokeratin or lineage-specific antibodies. Results: Concordant results were obtained in 55% (11 out of 20) of the patients with breast cancer, in 60% (12 out of 20) of the patients with prostate cancer and in only 20% (4 out of 20) of lung cancer patients. Conclusion: Our results highlight important discrepancies between the numbers of CTC enumerated by both techniques. These differences depend mostly on the tumour type. These results suggest that technologies limiting CTC capture to EpCAM-positive cells, may present important limitations, especially in patients with metastatic lung carcinoma. PMID:21829190

    Primary treatment of basal cell carcinoma of the lower eyelid and the inner corner is essentially surgical, but advanced lesions require extensive surgical interventions. In some cases it is necessary to continue with the mutilating surgery--exenteration of the orbit. In this work we evaluate the indications of radical solutions in patients with basal cell carcinoma invading the orbit and the subsequent possibility for individually made prosthesis to cover the defect of the cavity. Indications to exenteration of the orbit in patients with basal cell carcinoma findings in 2008-2013. Case report of 2 patients. In period 2008-20013 at the Dept. of Ophthalmology, Comenius University in Bratislava totally 221 patients with histologically confirmed basal cell carcinoma of the eyelids and the inner corner were treated. In 5 cases (2.7 %) with infiltration of the orbit the radical surgical procedure, exenteration was necessary. In 3 patients exenteration was indicated as the first surgical procedure in the treatment of basal cell carcinoma, since they had never visited ophthalmologist before only at in the stage of infiltration of the orbit (stage T4). In one case was indicated exenteration after previous surgical interventions and relapses. After healing the cavity patients got individually prepared epithesis. Surgical treatment of basal cell carcinoma involves the radical removal of the neoplasm entire eyelid and stage T1 or T2 can effectively cure virtually all tumors with satisfactory cosmetic and functional results. In advanced stages (T4 stage) by infiltrating the orbit by basal cell carcinoma exenteration of the orbit is necessary. This surgery is a serious situation for the patient and also for his relatives. Individually made prosthesis helps the patient to be enrolled to the social environment.

    Full Text Available Abstract Background Renal cell carcinoma can cause various paraneoplastic syndromes including metabolic and hematologic disturbances. Paraneoplastic hypereosinophilia has been reported in a variety of hematologic and solid tumors. We present the first case in the literature of severe paraneoplastic hypereosinophilia in a patient with renal cell carcinoma. Case presentation A 46 year-old patient patient with a history of significant weight loss, reduced general state of health and coughing underwent radical nephrectomy for metastasized renal cell carcinoma. Three weeks after surgery, the patient presented with excessive peripheral hypereosinophilia leading to profound neurological symptoms due to cerebral microinfarction. Systemic treatment with prednisolone, hydroxyurea, vincristine, cytarabine, temsirolimus and sunitinib led to reduction of peripheral eosinophils but could not prevent rapid disease progression of the patient. At time of severe leukocytosis, a considerable increase of cytokines associated with hypereosinophilia was measurable. Conclusions Paraneoplastic hypereosinophilia in patients with renal cell carcinoma might indicate poor prognosis and rapid disease progression. Myelosuppressive therapy is required in symptomatic patients.

    Lymphocyte subpopulations and cell-mediated cytotoxicity (CMI) were studied during radiation therapy in 16 patients with ovarian carcinoma. The total lymphocyte count became depressed in all patients. The depression was more marked among T cells, while the proportion of B cells remained unaffected. In patients with Stage I and II ovarian cancer, CMI was depressed significantly by radiotherapy after 7 days of treatment, remained low at 14 days but recovered despite continuation of radiation. This depression of CMI occurred at a delivered dose of 1,000 rads with subsequent recovery. Patients with Stage III ovarian cancer given pelvic and abdominal radiation were found to have no consistent depression of CMI, a finding similar to that in Stage III ovarian carcinoma patients given chemotherapy

    Circulating hepatocellular carcinoma cells may be detected by reverse transcription-polymerase chain reaction. We investigated the relationship between circulating hepatocellular carcinoma cells and hepatoma patient survival after different managements and survival periods. Peripheral vein blood (5 ml) samples were obtained from 113 patients with hepatocellular carcinoma and from 33 control subjects (9 with liver cirrhosis after hepatitis B, 14 with chronic hepatitis B, 10 healthy individuals) between January 1, 2009, and December 31, 2013. To detect circulating hepatocellular carcinoma cells in peripheral blood, alpha-fetoprotein messenger RNA was amplified from total RNA extracted from whole blood by reverse transcription-polymerase chain reaction. Alpha-fetoprotein messenger RNA was detected in 59 blood samples from the hepatocellular carcinoma patients (59/113, 52.2%). In contrast, there were no clinical control subjects whose samples showed detectable alpha-fetoprotein messenger RNA. The presence of alpha-fetoprotein messenger RNA in blood seemed to be correlated with the stage (by TNM classification) of hepatocellular carcinoma, serum alpha-fetoprotein value, and the presence of intrahepatic metastasis, portal vein thrombosis, tumor diameter and/or distant metastasis. In addition, alpha-fetoprotein messenger RNA was detected in the blood of 25 patients showing distant metastasis at extrahepatic organs (100%), in contrast to 32 of 88 cases without metastasis (36.4%). All the patients with hepatocellular carcinoma were followed. Seventeen patients with resection of a T 2 stage hepatocellular carcinoma had a survival of 3.2 years after surgical management, 38 cases with resection of a T3 stage hepatocellular carcinoma had a 1.3-year survival, and only 37 cases with T4 stage disease after different treatments except surgery survived for 0.6 years (P <0.01). The presence of alpha-fetoprotein messenger RNA in peripheral blood may be an indicator of circulating

    A case of clear cell carcinoma of the endometrium following squamous cell carcinoma of the cervix is reported. The patient had had a previous cervical biopsy which revealed squamous cell carcinoma (large cell non-keratinizing type), classified clinically as a stage IIb lesion. She was treated with external pelvic irradiation delivering an estimated tumor dose of approximately 7,000 rads and intracavital radium application delivering 4,995 mg.hr.radiation when she was 51 years old. She complained of post-menopausal bleeding at age 66 and was diagnosed by endometrial cytology as having clear cell carcinoma of the endometrium. Total abdominal hysterectomy, bilateral salpingo-oophorectomy and omentectomy were performed. The clinical stage of the endometrial cancer was Ib. She is alive after 2 years with no evidence of disease. Endometrial cytology revealed several adenocarcinoma cells in small clusters. The shape of the nuclei was somewhat irregular, the chromatin pattern was fine granular, and single or multiple nucleoli were seen. The diameter of these nuclei ranged from 10 to 30 μm. The cytoplasm was pale green or vacuolated. The volume of the cytoplasm varied from scanty to abundant. These findings suggested clear cell carcinoma. Histopathologically, an irregular shaped polypoid tumor, 3 x 1.5 cm in size, was located on the lower anterior wall of the uterine corpus. The tumor was a clear cell carcinoma showing a solid and papillary pattern. A hobnail pattern was not observed. The cytoplasm was clear and abundant, and PAS-positive granules digestible by diastase were seen. These 2 cancers had different pathological features and their immunohistochemical reactivities for CEA and keratin were also different. The patient was regarded as having a rare heterochronous double cancer consisting of squamous cell carcinoma of the cervix and clear cell carcinoma of the endometrium. (author)

    Differentiation is a major histological parameter determining tumor aggressiveness and prognosis of the patient; cancer stem cells with their slow dividing and undifferentiated nature might be one of the factors determining the same. This study aims to correlate cancer stem cell markers (CD44 and CD147) with tumor differentiation and evaluate their subsequent effect on prognosis. Immunohistochemical analysis in treatment naïve oral cancer patients (n = 53) indicated that the expression of CD147 was associated with poorly differentiated squamous cell carcinoma and moderately differentiated squamous cell carcinoma (p squamous cell carcinoma and poorly differentiated squamous cell carcinoma patients were CD44 high /CD147 high as compared to only 10% of patients with well-differentiated squamous cell carcinoma. A three-way analysis indicated that differentiation correlated with recurrence and survival (p oral squamous cell carcinoma cell lines originating from different grades of oral cancer. Flowcytometry-based analysis indicated an increase in CD44 + /CD147 + cells in cell lines of poorly differentiated squamous cell carcinoma (94.35 ± 1.14%, p squamous cell carcinoma origin (93.49 ± 0.47%, p squamous cell carcinoma origin (23.12% ± 0.49%). Expression profiling indicated higher expression of cancer stem cell and epithelial-mesenchymal transition markers in SCC029B (poorly differentiated squamous cell carcinoma originated; p ≤ 0.001), which was further translated into increased spheroid formation, migration, and invasion (p squamous cell carcinoma origin. This study suggests that CD44 and CD147 together improve the prognostic efficacy of tumor differentiation; in vitro results further point out that these markers might be determinant of differentiation characteristics, imparting properties of increased self-renewal, migration, and invasion.

  6. 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 Hedgehog pathway inhibitor vismodegib has shown clinical benefit in patients with advanced basal cell carcinoma and is approved for treatment of patients with advanced basal cell carcinoma for whom surgery is inappropriate. STEVIE was designed to assess the safety of vismodegib in a situation similar to routine practice, with a long follow-up. In this multicentre, open-label trial, adult patients with histologically confirmed locally advanced basal cell carcinoma or metastatic basal cell carcinoma were recruited from regional referral centres or specialist clinics. Eligible patients were aged 18 years or older with an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2, and adequate organ function. Patients with locally advanced basal cell carcinoma had to have been deemed ineligible for surgery. All patients received 150 mg oral vismodegib capsules once a day on a continuous basis in 28-day cycles. The primary objective was safety (incidence of adverse events until disease progression or unacceptable toxic effects), with assessments on day 1 of each treatment cycle (28 days) by principal investigator and coinvestigators at the site. Efficacy variables were assessed as secondary endpoints. The safety evaluable population included all patients who received at least one dose of study drug. Patients with histologically confirmed basal cell carcinoma who received at least one dose of study drug were included in the efficacy analysis. An interim analysis was pre-planned after 500 patients achieved 1 year of follow-up. This trial is registered with ClinicalTrials.gov, number NCT01367665. The study is still ongoing. Between June 30, 2011, and Nov 6, 2014, we enrolled 1227 patients. At clinical cutoff (Nov 6, 2013), 499 patients (468 with locally advanced basal cell carcinoma and 31 with metastatic basal cell carcinoma) had received study drug and had the potential to be followed up for 12 months or longer. Treatment was discontinued in 400 (80

    Limited information is available regarding disease awareness and sun protection behaviour in patients previously treated for non-melanoma skin cancer. Using a telephone-administered questionnaire, we investigated these characteristics in 250 patients in the west of Ireland who had undergone excision of basal cell carcinomas between January 2011 and December 2012. Only 28.8% of respondents knew that the lesion they had excised was a BCC and understood that there was a significant chance of developing another similar lesion in the next 3 years. Women and patients under age 65 were significantly better informed about their diagnosis than men (p = 0.021 and 0.000 respectively). The majority of patients (71.2%) knew that the overall effect of UV radiation on the skin was harmful and did employ some form of sun protection (avoid midday sun 72%; stay in shade 74%; wear hat 73.6%; wear sunscreen 72.8%). Females were statistically more likely to exercise better sun-protection behaviour (p = 0.002). While 76.8% of patients undertook some form of outdoor activity every day, only 22.8% wore sunscreen every day. Greater efforts should be made to communicate disease details and sun protection implications associated with basal cell carcinoma, especially to male patients. Improved population specific skin cancer awareness may lead to earlier detection and thus decrease both the patient morbidity and economic burden associated with locally advanced basal cell carcinoma.

    Background Correct detection of bone metastases in patients with esophageal squamous cell carcinoma is pivotal for prognosis and selection of an appropriate treatment regimen. Whole-body bone scan for staging is not routinely recommended in patients with esophageal squamous cell carcinoma. The aim of this study was to investigate the role of bone scan in detecting bone metastases in patients with esophageal squamous cell carcinoma. Methods We retrospectively evaluated the radiographic and scintigraphic images of 360 esophageal squamous cell carcinoma patients between 1999 and 2008. Of these 360 patients, 288 patients received bone scan during pretreatment staging, and sensitivity, specificity, positive predictive value, and negative predictive value of bone scan were determined. Of these 360 patients, surgery was performed in 161 patients including 119 patients with preoperative bone scan and 42 patients without preoperative bone scan. Among these 161 patients receiving surgery, 133 patients had stages II + III disease, including 99 patients with preoperative bone scan and 34 patients without preoperative bone scan. Bone recurrence-free survival and overall survival were compared in all 161 patients and 133 stages II + III patients, respectively. Results The diagnostic performance for bone metastasis was as follows: sensitivity, 80%; specificity, 90.1%; positive predictive value, 43.5%; and negative predictive value, 97.9%. In all 161 patients receiving surgery, absence of preoperative bone scan was significantly associated with inferior bone recurrence-free survival (P = 0.009, univariately). In multivariate comparison, absence of preoperative bone scan (P = 0.012, odds ratio: 5.053) represented the independent adverse prognosticator for bone recurrence-free survival.

    Heparanase is an enzyme that cleaves heparan sulfate chains. Oligosaccharides generated by heparanase induce tumor progression. Basal cell carcinoma and squamous cell carcinoma comprise types of nonmelanoma skin cancer. Evaluate the glycosaminoglycans profile and expression of heparanase in two human cell lines established in culture, immortalized skin keratinocyte (HaCaT) and squamous cell carcinoma (A431) and also investigate the expression of heparanase in basal cell carcinoma, squamous cell carcinoma and eyelid skin of individuals not affected by the disease (control). Glycosaminoglycans were quantified by electrophoresis and indirect ELISA method. The heparanase expression was analyzed by quantitative RT-PCR (qRTPCR). The A431 strain showed significant increase in the sulfated glycosaminoglycans, increased heparanase expression and decreased hyaluronic acid, comparing to the HaCaT lineage. The mRNA expression of heparanase was significantly higher in Basal cell carcinoma and squamous cell carcinoma compared with control skin samples. It was also observed increased heparanase expression in squamous cell carcinoma compared to the Basal cell carcinoma. The glycosaminoglycans profile, as well as heparanase expression are different between HaCaT and A431 cell lines. The increased expression of heparanase in Basal cell carcinoma and squamous cell carcinoma suggests that this enzyme could be a marker for the diagnosis of such types of non-melanoma cancers, and may be useful as a target molecule for future alternative treatment.

    Literature data indicates that measurement of certain salivary constituents might serve as a useful diagnostic/prognostic tool in the patients with oral squamous cell carcinoma (OSCC). In 24 patients with OSCC (60 +/- 2.5 yrs) and in 24 controls (24 +/- 3.7 yrs) we have determined levels of salivary magnesium, calcium, copper, chloride, phosphate, potassium, sodium, total proteins and amylase. Sodium, potassium and chloride were determined by indirect potentiometry whereas copper, magnesium and phosphate were determined by atomic absorption spectrophotometry. Total proteins were determined by pyrogalol colorimetric method. Amylase levels were determined by continued colorimetric method. Statistical analysis was performed by use of chi2 test and Spearman's correlation test. The results of this study indicate that the concentrations of sodium and chloride were significantly elevated in patients with OSCC when compared to the controls. However, level of total protein was significantly decreased when compared to the healthy controls. Furthermore, there was a negative correlation between alcohol consumption and total protein concentration in patients with oral carcinoma. We might conclude that in patients with OSCC increased salivary sodium and chloride might reflect their overall dehydration status due to alcohol consumption rather than consequence of OSCC itself.

    Full Text Available Purpose: In clinical practice, radiation therapy often fails in cervical carcinoma stage IIIB and there is a need to develop a predictive assay for prognosis of radiation treatment outcome in cancer patient. We have attempted to evaluate the relevance of changes in Membrane Fluidity (MF and associated apoptotic cell death in cervical cancer cells after first fractionated dose of radiation therapy to treatment outcome of stage IIIB cervical carcinoma patients. Materials and Methods: Biopsies of 15 patients with histologically proven cervix cancer were collected from the patients before and 24 h after first fractionated radiation dose of 2 grays (Gy. Cell suspension made in Dulbecco′s Modified Eagle′s Medium (DMEM were used for further investigations and cell suspension of cervix cancer patient were used to measure MF by fluorescence polarization method and apoptotic index (AI was determined by Tdt dUTP Nucleotide End Labeling (TUNEL assay. Results: A substantial increase in MF and AI was observed in cervical cancer cells irradiated ex vivo . A significant correlation ( P < 0.001 was found between the changes in AI after first fractionated dose of radiotherapy and treatment outcome of patients. No significant correlation ( P > 0.1 was detected between changes in MF and treatment outcome of patients. Conclusion: Preliminary results showed significant change in MF and a marked increase in percentage apoptosis of cervix cancer cells irradiated ex vivo . The changes in AI after first fractionated dose of radiotherapy in cervical carcinoma patients may provide a predictor of prognosis for radiotherapy in uterine cervical carcinoma patients.

    Introduction. Basal cell carcinoma (BCC) is a locally invasive malignant epidermal tumour. Incidence is increasing by 10% per year; incidence of metastases is minimal, but relapses are frequent (40%-50%). The complete excision of the BCC allows reduction of relapse. Materials and Methods. The study cohort consists of 1123 patients underwent surgery for basal cell carcinoma between 1999 and 2009. Patient and tumor characteristics recorded are: age; gender; localization (head and neck, trunk, and upper and lower extremities), tumor size, excisional margins adopted, and relapses. Results. The study considered a group of 1123 patients affected by basal cell carcinoma. Relapses occurred in 30 cases (2,67%), 27 out of 30 relapses occurred in noble areas, where peripheral margin was <3mm. Incompletely excised basal cell carcinoma occurred in 21 patients (1,87%) and were treated with an additional excision. Discussion. Although guidelines indicate 3mm peripheral margin of excision in BCC <2cm, in our experience, a margin of less than 5mm results in a high risk of incomplete excisions

    Full Text Available Gorlin-Goltz syndrome or basal cell nevus syndrome is an autosomal dominant syndrome characterized by skeletal anomalies, numerous cysts observed in the jaw, and multiple basal cell carcinoma of the skin, which may be accompanied by falx cerebri calcification. Basal cell carcinoma is the most commonly skin tumor with slow clinical course and low metastatic potential. Its concomitance with Gorlin syndrome, resulting from a mutation in a tumor suppressor gene, may substantially change morbidity and mortality. A 66-year-old male patient with a history of recurrent basal cell carcinoma was presented with exophthalmus in the left eye and the lesions localized in the left lateral orbita and left zygomatic area. His physical examination revealed hearing loss, gapped teeth, highly arched palate, and frontal prominence. Left orbital mass, cystic masses at frontal and ethmoidal sinuses, and multiple pulmonary nodules were detected at CT scans. Basal cell carcinoma was diagnosed from biopsy of ethmoid sinus. Based on the clinical and typical radiological characteristics (falx cerebri calcification, bifid costa, and odontogenic cysts, the patient was diagnosed with metastatic skin basal cell carcinoma accompanied by Gorlin syndrome. Our case is a basal cell carcinoma with aggressive course accompanying a rarely seen syndrome.

    OBJECTIVE: To compare the repetitive DNA patterns of human actinic keratoses and squamous cell carcinomas to determine the genetic alterations that are associated with malignant transformation. INTRODUCTION: Cancer cells are prone to genomic instability, which is often due to DNA polymerase slippage during the replication of repetitive DNA and to mutations in the DNA repair genes. The progression of benign actinic keratoses to malignant squamous cell carcinomas has been proposed by several authors. MATERIAL AND METHODS: Eight actinic keratoses and 24 squamous cell carcinomas (SCC), which were pair-matched to adjacent skin tissues and/or leucocytes, were studied. The presence of microsatellite instability (MSI) and the loss of heterozygosity (LOH) in chromosomes 6 and 9 were investigated using nine PCR primer pairs. Random Amplified Polymorphic DNA patterns were also evaluated using eight primers. RESULTS: MSI was detected in two (D6S251, D9S50) of the eight actinic keratosis patients. Among the 8 patients who had squamous cell carcinoma-I and provided informative results, a single patient exhibited two LOH (D6S251, D9S287) and two instances of MSI (D9S180, D9S280). Two LOH and one example of MSI (D6S251) were detected in three out of the 10 patients with squamous cell carcinoma-II. Among the four patients with squamous cell carcinoma-III, one patient displayed three MSIs (D6S251, D6S252, and D9S180) and another patient exhibited an MSI (D9S280). The altered random amplified polymorphic DNA ranged from 70% actinic keratoses, 76% squamous cell carcinoma-I, and 90% squamous cell carcinoma-II, to 100% squamous cell carcinoma-III. DISCUSSION: The increased levels of alterations in the microsatellites, particularly in D6S251, and the random amplified polymorphic DNA fingerprints were statistically significant in squamous cell carcinomas, compared with actinic keratoses. CONCLUSION: The overall alterations that were observed in the repetitive DNA of actinic keratoses and

    Full Text Available Background and objective Activating mutations in epidermal growth factor receptor (EGFR and KRAS are important markers in non-small cell lung cancer. However, EGFR and KRAS gene mutations in lung squamous cell carcinoma are rarely reported. The aim of this study was to analyze EGFR and KRAS gene mutation rate and their relationship with clinical features in patients with lung squamous cell carcinomas. Methods A total of 139 patients undergoing treatment for naïve lung squamous cell carcinomas with tumor tissue samples available for testing were recruited. EGFR and KRAS mutation statuses of the tumor samples were detected using a mutant enriched liquid chip. Results Of the 139 cases of lung squamous cell carcinoma, EGFR mutations were detected in 25 cases (18%, KRAS mutations were detected in 7 cases (5%, and the presence of both EGFR and KRAS mutations was detected in 1 case (0.7%. EGFR mutations occurred more often in females than in males (33.3% vs 16.5% and in patients that never smoked than in those who smoke (29.6% vs 16.1%. However, the difference did not reach statistical significance (P>0.05. No significant differences were observed in age, stage, and different biopsy type. KRAS mutations occurred more often in males than in females (5.5% vs 0%, but the difference did not reach statistical significance (P>0.05. No significant differences were observed in age, stage, different biopsy type, and smoking status (P>0.05. Conclusion EGFR and KRAS mutations were low in lung squamous cell carcinomas, and had no significant correlation with clinical features. Before using tyrosine kinase inhibitor targeted therapy, EGFR and KRAS mutations should be detected in patients with lung squamous cell carcinomas.

    Full Text Available Two kinds of different malignant tumors occurring within the same organ is defined as collision tumor. Small Cell Carcinoma (SmCC is high-grade derived from neuroendocrine cell tumors, occurance in the head and neck is rare. Squamous Cell Carcinoma (SCC is the most common malignancies encountered in head and neck area, but the occuranceof collision tumor is very rare. This report describe a 82 year-old woman patient with a SmCC and SCC that occurred in the maxillary sinus. CT was performed including with enhancement, MRI examination was T1WI, STIR and contrast enhancement. We also conducted analysis of Dynamic Contrast Enhancement (DCE. Histopathologic examination revealed small cell carcinoma. A distant metastasis was not detected. After patient received chemoradiotherapy (CCRT, most of  tumorwas reduced although a part of the tumor was remained. Pathological examination of surgery tumor specimen revealed that specimen consisted of SCC and SmCC was disappeared, and six months after surgery, the patient suffered tumor recurrence and multiple metastasis to the organs in the abdomen. This time we have to report that the experience one cases that are considered collision cancer of SmCC and SCC that occurred in the maxillary sinus.

    1977-01-01

    A heterologous antiserum for human cervical squamous cell carcinoma was prepared and specificity determined by Ouchterlony immunodiffusion and immunofluorescence studies. With this antiserum, a tumor antigen was purified from human cervical squamous cell carcinoma tissue. The specificities of the antigen and the antiserum were then re-examined by a radioimmunoassay method using 125 I-labeled purified antigen. Although normal cervical tissue extract showed a moderate cross-reactivity in the radioimmunoassay, the circulating antigen activity could not be detected in normal women or in several patients with other carcinomas, whereas 27 of 35 patients with cervical squamous cell carcinoma showed detectable serum antigen activity. All patients with advanced stages of cervical squamous cell carcinoma showed detectable antigen levels. These results indicate that there is a quantitative abnormality, at least, of this tumor antigen in patients with cervical squamous cell carcinoma and that the radioimmunoassay for the antigen is a potentially useful tool in clinical care

    Full Text Available Primary orbital squamous cell carcinoma is a rare entity. There is little published literature. We report a case of primary squamous cell carcinoma of the orbital soft tissues. Surgical resection offered the best treatment for the patient. Complete resection of the lesion was achieved. The patient received adjuvant radiotherapy due to the proximity of the lesion to the surgical margins. Surgical treatment is feasible and should be considered as part of the surgeon's arsenal. However, therapeutic decisions must be made on a case-by-case basis

    2011-12-01

    Full Text Available The treatment of metastatic renal cell carcinoma (RCC has changed dramatically with the introduction of targeted therapies including sunitinib, sorafenib, and temsirolimus. Because patients with conventional clear cell histology account for 75- 80% of all patients with RCC, there has been little accumulated evidence on the treatment of patients with non-clear cell histologies. Most clinical trials have excluded them from enrolment, except for randomized studies investigating temsirolimus. Many retrospective studies on the use of all three of these targeted therapies in patients with non-clear cell histology have demonstrated response rates ranging from 3.7%–16%. Although response rates may not be as high compared to patients with clear cell histologies, targeted therapy does provide a clinically meaningful response.

    Despite aggressive regimens, the clinical outcome of head and neck squamous cell carcinoma remains poor. The detection of circulating tumor cells could potentially improve the management of patients with disseminated cancer, including diagnosis, treatment strategies, and surveillance. Currently, CellSearch ® is the most widely used and the only Food and Drug Administration-cleared system for circulating tumor cells detection in patients with metastatic breast, colorectal, or prostate cancer. In most cases of head and neck squamous cell carcinoma, only low counts of circulating tumor cells have been reported. A 56-year-old white male with no particular medical history, was diagnosed with a squamous cell carcinoma of oral cavity. According to the imaging results (computed tomography and 18 F-fluorodeoxyglucose positron emission tomography / computed tomography) and panendoscopy, the TNM staging was classified as T4N2M0. A non-interruptive pelvimandibulectomy was conducted according to the multidisciplinary meeting advices and the postoperative observations were normal. The patient complained of a painful cervical edema and a trismus 6 weeks after the surgery. A relapse was found by computed tomography and the patient died two weeks later. The search for circulating tumor cells in peripheral venous blood by using the CellSearch ® system revealed a very high count compared with published reports at three time points (pre-operative: 400; intra-operative: 150 and post-operative day 7: 1400 circulating tumor cells). Of note, all detected circulating tumor cells were epidermal growth factor receptor negative. We report here for the first time a rare case of oral squamous cell carcinoma with extremely high circulating tumor cells counts using the CellSearch ® system. The absolute number of circulating tumor cells might predict a particular phase of cancer development as well as a poor survival, potentially contributing to a personalized healthcare

    The behaviour of each basal cell carcinoma is known to be different according to the histological growth pattern. Among these aggressive lesions, sclerodermiform basal cell carcinomas are the most common type. This is a challenging-to-treat lesion due to its deep tissue invasion, rapid growth, risk of metastasis and overall poor prognosis if not diagnosed in early stages. To investigate if sclerodermiform basal cell carcinomas are diagnosed later compared to non-sclerodermiform basal cell carcinoma Method: All lesions excised from 2000 to 2010 were included. A pathologist classified the lesions in two cohorts: one with specimens of non-aggressive basal cell carcinoma (superficial, nodular and pigmented), and other with sclerodermiform basal cell carcinoma. For each lesion, we collected patient's information from digital medical records regarding: gender, age when first attending the clinic and the tumor location. 1256 lesions were included, out of which 296 (23.6%) corresponded to sclerodermiform basal cell carcinoma, whereas 960 (76.4%) were non-aggressive subtypes of basal cell carcinoma. The age of diagnosis was: 72.78±12.31 years for sclerodermiform basal cell and 69.26±13.87 years for non-aggressive basal cell carcinoma (Pbasal cell carcinomas are diagnosed on average 3.52 years later than non-aggressive basal cell carcinomas. Sclerodermiform basal cell carcinomas were diagnosed 3.40 years and 2.34 years later than non-aggressive basal cell carcinomas in younger and older patients respectively (P=.002 and P=.03, respectively). retrospective design. The diagnostic accuracy and primary clinic conjecture of sclerodermiform basal cell carcinomas is quite low compared to other forms of basal cell carcinoma such as nodular, superficial and pigmented. The dermoscopic vascular patterns, which is the basis for the diagnosis of non-melanocytic nonpigmented skin tumors, may not be particularly useful in identifying sclerodermiform basal cell carcinomas in early stages

    The purpose of this study was to evaluate the prognostic impact of endoscopic traversability in patients with locally advanced esophageal squamous cell carcinoma.This retrospective study was based on medical records from a single tertiary medical center. The records of 317 patients with esophageal squamous cell carcinoma treated with surgery or definitive chemoradiotherapy (CRT) between January 2009 and March 2016 were reviewed. Finally, we retrieved the data on 168 consecutive patients. These 168 patients were divided into 2 groups based on their endoscopic traversability findings: Group A (the endoscope traversable group), and Group B (the endoscope non-traversable group). We then retrospectively compared the clinical characteristics of these 2 groups.The endoscope non-traversable group (Group B) revealed an advanced clinical stage, a poor Eastern Cooperative Oncology Group (ECOG) score, a lower serum albumin level, a higher rate of requirement for esophageal stent insertion and definitive CRT as initial treatment than the endoscope traversable group (Group A). Patients with endoscope traversable cancer showed a significantly higher 3-year overall survival and 3-year relapse-free survival than patients who were endoscope non-traversable (53.8% vs 17.3%, P squamous cell carcinoma treated with definitive CRT, the serum albumin level squamous cell carcinoma treated with definitive CRT is a significant prognostic factor.

  10. Vismodegib (ERIVEDGE°) In basal cell carcinoma: too many unknowns.

    Science.gov (United States)

    2015-01-01

    Basal cell carcinomas are the most common skin cancers. They are usually localised and carry a good prognosis. There is no standard treatment for the rare patients with metastatic basal cell carcinoma or very extensive basal cell carcinoma for whom surgery or radiotherapy is inappropriate. Vismodegib, a cytotoxic drug, is claimed to prevent tumour growth by inhibiting a pathway involved in tissue repair and embryogenesis. It has been authorised in the European Union for patients with metastatic or locally advanced and extensive basal cell carcinoma. Clinical evaluation of vismodegib is based on a non-comparative clinical trial involving 104 patients, providing only weak evidence. Twenty-one months after the start of the trial, 7 patients with metastases (21%) and 6 patients with advanced basal cell carcinoma (10%) had died. Given the lack of a placebo group, there is no way of knowing whether vismodegib had any effect, positive or negative, on survival. There were no complete responses among patients with metastases, but about one-third of them had partial responses. Among the 63 patients with locally advanced basal cell carcinoma, there were 14 complete responses and 16 partial responses. The recurrence rate in patients with complete responses was not reported. Similar results were reported in two other uncontrolled trials available in mid-2014. Vismodegib has frequent and sometimes serious adverse effects, including muscle spasms, fatigue and severe hyponatraemia. Cases of severe weight loss, alopecia, ocular disorders, other cancers (including squamous cell carcinoma) and anaemia have also been reported. More data are needed on possible hepatic and cardiovascular adverse effects. A potent teratogenic effect was seen in experimental animals. As vismodegib enters semen, contraception is mandatory for both men (condoms) and women. In practice, vismodegib has frequent and varied adverse effects, some of which are serious, while its benefits are poorly documented

    Full Text Available We report a case of primary extrapulmonary small cell carcinoma of the distal ureter, with a synchronous small cell carcinoma of the ipsilateral renal pelvis. These tumors, rarely reported in the urinary tract, are locally aggressive and have a poor prognosis. A 77-year-old male bedridden patient presented with fever and chills with left side-flank pain for 3 days. Following a diagnosis of ureteral urothelial carcinoma, hand-assisted laparoscopic nephroureterectomy with bladder cuff excision was carried out. Adjuvant chemotherapy was given after pathologic report of primary small cell carcinoma of the distal ureter and a synchronous small cell carcinoma of the ipsilateral renal pelvis. After 3 cycles of combination chemotherapy, the patient died 4 months postoperatively due to sepsis.

    Merkel cell carcinoma is a rare skin tumor of neural crest origin and is part of the amine precursor uptake and decarboxylase system. It typically occurs on the face of elderly people. Distant metastasis is almost uniformly fatal. Choroidal metastasis, to our knowledge, has not been described. We report a patient with Merkel cell carcinoma who had a synchronous solid choroidal tumor and a biopsy-proven brain metastasis. Our 56-year-old patient presented with a rapidly growing, violaceous preauricular skin tumor. Computed tomography of the head disclosed incidental brain and choroidal tumors. Light and electron microscopy of biopsy specimens of both the skin and the brain lesions showed Merkel cell carcinoma. Ophthalmoscopy, fluorescein angiography, and A and B echography revealed a solid choroidal mass. The brain and skin tumors responded well to irradiation. A radioactive episcleral plaque was applied subsequently to the choroidal tumor. All tumors regressed, and the patient was doing well 28 months later. To our knowledge this is the first case of presumed choroidal metastasis of Merkel cell carcinoma

    Gorlin-Goltz syndrome, also known as nevoid basal cell carcinoma syndrome, is an autosomal dominant inherited disorder which is characterized by the presence of multiple basal cell carcinomas, maxillary keratocysts, and musculoskeletal anomalies. We present a case of a patient suffering from Gorlin-Goltz syndrome who developed an intraosseous basal cell carcinoma associated with a recurrent maxillary keratocyst. To our knowledge, this is the first case of malignant transformation of a keratocyst into a basal cell carcinoma described in the literature. This case highlights the importance of careful histologic examination of keratocysts excised in patients suffering from Gorlin-Goltz syndrome.

    Currently, non-small cell lung carcinomas are primarily classified by light microscopy. However, recent studies have shown that poorly-differentiated tumors are more accurately classified by immunohistochemistry. In this study, we investigated the use of immunohistochemical analysis in reclassifying lung carcinomas that were originally diagnosed as squamous cell carcinoma. Tumor slides and blocks were available for histologic evaluation, and tissue microarrays were constructed from 480 patients with resected lung carcinomas originally diagnosed as squamous cell carcinoma between 1999 and 2009. Immunohistochemistry for p40, p63, thyroid transcription factor-1 (TTF-1; clone SPT24 and 8G7G3/1), Napsin A, Chromogranin A, Synaptophysin, and CD56 were performed. Staining intensity (weak, moderate, or strong) and distribution (focal or diffuse) were also recorded. Of all, 449 (93.5%) patients were confirmed as having squamous cell carcinomas; the cases were mostly diffusely positive for p40 and negative for TTF-1 (8G7G3/1). Twenty cases (4.2%) were reclassified as adenocarcinoma since they were positive for TTF-1 (8G7G3/1 or SPT24) with either no or focal p40 expression, and all of them were poorly-differentiated with squamoid morphology. In addition, 1 case was reclassified as adenosquamous carcinoma, 4 cases as large cell carcinoma, 4 cases as large cell neuroendocrine carcinoma, and 2 cases as small cell carcinoma. In poorly-differentiated non-small cell lung carcinomas, an accurate distinction between squamous cell carcinoma and adenocarcinoma cannot be reliably determined by morphology alone and requires immunohistochemical analysis, even in resected specimens. Our findings suggest that TTF-1 8G7G3/1 may be better suited as the primary antibody in differentiating adenocarcinoma from squamous cell carcinoma. PMID:25871623

    Full Text Available We report a rare case of synchronous presentation of nasopharyngeal and renal cell carcinomas in a-50-year old male patient with long standing smoking history. The patient was initially presented with a diagnosis of nasopharyngeal carcinoma. During staging process, the abdominal computed tomography detected a right renal solid mass, 6.5 cm in diameter, originating from posterior portion of the right renal cortex. Right radical nephrectomy was performed and pathological examination revealed renal cell carcinoma. Smoking was thought to be a risk factor for both cancers. Systemic evaluation of kidney should not be discarded in patients diagnosed with nasopharyngeal carcinoma living in western countries with a smoking history.

    Full Text Available Squamous cell carcinoma of the skin (SSCC is one of the most common malignant skin tumors. Syphilis is a sexually transmitted disease caused by Treponema pallidum, with human beings as the only host. The combination of syphilis and squamous cell carcinoma of the skin is not uncommon, particularly if the lesions are located on different parts of the body. However, simultaneous development of the chancre and squamous cell carcinoma of the glans penis seems exceptional. Considering rarity of the manifestation observed we feel the rare case of combined syphilis and squamous cell skin cancer is of interest.

    Most common malignant tumour of the kidney is Renal Cell Carcinoma (RCC) and is known for its unpredictable clinical behaviour. Aetiology and risk factors are not completely understood. Extensive workup is being done in the understanding of the disease, especially to diagnose early and to treat promptly. The objective of this study was to determine the clinical presentation and pathological pattern of RCC. Methods: After approval from ethical committee a retrospective review of records was conducted extending from January 2012 to January 2014 to identify clinical characteristics of renal cell carcinomas. The study included all renal cancer patients presented to Sheikh Zayed Hospital Lahore with in this specified period. The data was retrieved regarding, history, physical examination and necessary investigations such as ultrasonography of abdomen and pelvis and CT scan of abdomen and pelvis. Results: There were total of 50 cases. The male to female ratio was 3:2. Mean age of patients were 52.38 (18-93) years old. Most common clinical presentation was gross haematuria(66%).The mean tumour size was 8.34 (3-24) cm. Tumour histology were clear cell (84%), papillary transitional cell carcinoma (12%) and oncosytoma contributed 4%. Conclusion: We observed that large number of the patients with RCC presented with haematuria and most of them were male. Common pathological type was clear cell carcinoma. (author)

    Primary squamous cell carcinoma of the stomach is very rare. Its pathogenesis is unclear and the treatment strategy is controversial. We report an agressive primary squamous cell carcinoma of the stomach with liver and lung metastases in a 55-year-old man. The patient presented with a 1-month history of abdominal pain, vomiting and weight loss. Abdominal ultrasound revealed multiple liver metastases. Endoscopic examination showed two tumour masses on the fundus of the stomach. Biopsy of the lesions revealed squamous cell carcinoma of the stomach. Chest x-ray showed multiple large pulmonary nodules highly suggestive of pulmonary metastases. The patient died ten days after he was admitted because of progression of the tumour and before any therapeutic decision.

    Fanconi anemia is a recessively inherited disease that is characterized by congenital abnormalities, bone marrow failure, and a predisposition to develop cancer, particularly squamous cell carcinomas (SCCs) in the head and neck and anogenital regions. Previous studies of Fanconi anemia SCCs, mainly from US patients, revealed the presence of high-risk human papillomavirus (HPV) DNA in 21 (84%) of 25 tumors analyzed. We examined a panel of 21 SCCs mainly from European Fanconi anemia patients (n = 19 FA patients; 16 head and neck squamous cell carcinomas [HNSCCs], 2 esophageal SCCs, and 3 anogenital SCCs) for their clinical and molecular characteristics, including patterns of allelic loss, TP53 mutations, and the presence of HPV DNA by GP5+/6+ polymerase chain reaction. HPV DNA was detected in only two (10%) of 21 tumors (both anogenital SCCs) but in none of the 16 HNSCCs. Of the 18 tumors analyzed, 10 contained a TP53 mutation. The patterns of allelic loss were comparable to those generally found in sporadic SCCs. Our data show that HPV does not play a major role in squamous cell carcinogenesis in this cohort of Fanconi anemia patients and that the Fanconi anemia SCCs are genetically similar to sporadic SCCs despite having a different etiology.

    Basal cell carcinoma is the most common skin cancer. Myoepithelial cells are specialized epithelial cells. Basal cell carcinoma with myoepithelial differentiation is a rare tumor. A 71-year-old man with a basal cell carcinoma with myoepithelial differentiation that presented as an asymptomatic red papule of two months duration on his forehead is described. Including the reported patient, this variant of basal cell carcinoma has been described in 16 patients: 11 men and five women. The patients ranged in age at diagnosis from 43 years to 83 years; the median age at diagnosis was 66 years. All of the tumors were located on the face-most were papules or nodules of less than 10 x 10 mm. Their pathology demonstrated two components: one was that of a typical basal cell carcinoma and the other was myoepithelioma-like in which the tumor cells were plasmacytoid or signet ring in appearance and contained abundant eosinophilic cytoplasm or hyaline inclusions or both. The myoepithelial tumor cells had variable immunohistochemical expression that included not only cytokeratin but also actin, glial fibrillary acid protein, S100, and vimentin. The most common clinical impression, prior to biopsy, was a basal cell carcinoma. The pathologic differential diagnosis included cutaneous mixed sweat gland tumor of the skin, myoepithelioma, myoepithelial carcinoma, and tumors that contain a prominent signet ring cell component (such as metastatic gastrointestinal and breast carcinoma, melanoma, plasmacytoid squamous cell carcinoma, and T-cell lymphoma). Mohs micrographic surgical excision, with complete removal of the tumor, was recommended for treatment of the carcinoma.

    Non-specific cellular immunity of patients with upper urinary tract carcinoma was studied by PPD reaction (in vivo or in vitro), lymphocytes subpopulation and macrophage migration inhibition test and the results were compared with those of patients with bladder carcinoma or benign urological diseases. 1) The preoperative cellular immunity of the malignant tumor group gave low values as compared to that in the benign disease group. Although the cellular immunity of patients with renal cell carcinoma showed no difference in the points of their grade and stage, significant differences were noted in patients with bladder carcinoma. The patients with renal pelvic and ureter carcinoma appeared to be similar to the patients with bladder carcinoma in the aspects of immune reactions. 2) In the majority of patients with upper urinary tract and bladder carcinoma, the cellular immunity after complete removal of the carcinoma gave an increased value of each marker as compared to the preoperative value. 3) The cellular immunity after irradiation decreased in the majority of the cases in terms of PPD reaction and T-cell ratio in lymphocyte subpopulation. Irradiation of 4000 - 6000 Rad. showed greater influence on T-cell than on B-cell, but influence of irradiation on cellular immunity was not different by irradiation dose. 4) The cellular immunity indicated decreased values for one to two months after discontinuation of irradiation, but then it showed a tendency to increase in terms of PPD and lymphocytes subpopulation in the patients with satisfactory postoperative courses. 5) Through the pre and postoperative courses, the immunity of the carcinomatous stage seems to be reflected better by the T-cell ratio than by the absolute number of T-cell. It is likely that macrophage migration inhibition test shows much sharper reaction than PPD reaction. (author)

    The aim was to determine the long-term prognosis in patients with stage IIIb-IVa squamous cell carcinoma of the cervix who were treated with intra-arterial neoadjuvant chemotherapy (NAC), and to analyze factors related to prognostic value. The authors assessed the disease-free survival of 21 patients with FIGO stage IIIb-IVa squamous cell carcinoma of the cervix treated with intra-arterial NAC followed by irradiation therapy. Before chemotherapy, five factors (age, clinical stage, histologic type, parametrial involvement and serum level of SCC) were evaluated for their correlation with disease-free survival. Univariate Cox's proportional hazard model also demonstrated that age was a significant prognostic factor as a continuous variable. Intra-arterial NAC thus appeared to be effective in treating older patients with stage IIIb-IVa squamous cell carcinoma of the cervix

    Full Text Available We herein report a rare case of squamous cell carcinoma of the hilar bile duct. A 66-year-old Japanese male patient was admitted to our hospital because of appetite loss and jaundice. Abdominal computed tomography revealed an enhanced mass measuring 10 × 30 mm in the hilar bile duct region. After undergoing biliary drainage, the patient underwent extended right hepatic lobectomy with regional lymph nodes dissection. The tumor had invaded the right portal vein. Therefore, we also performed resection and reconstruction of the portal vein. Histopathologically, the carcinoma cells exhibited a solid structure with differentiation to squamous cell carcinoma with keratinization and intercellular bridges. Immunohistochemical staining of the tumor cells revealed positive cytokeratin staining and negative CAM 5.2 staining. Based on these findings, a definitive diagnosis of well-differentiated squamous cell carcinoma of the hilar bile duct was made.

    A case of clear cell carcinoma of the endometrium following squamous cell carcinoma of the cervix is reported. The patient had had a previous cervical biopsy which revealed squamous cell carcinoma (large cell non-keratinizing type), classified clinically as a stage IIb lesion. She was treated with external pelvic irradiation delivering an estimated tumor dose of approximately 7,000 rads and intracavital radium application delivering 4,995 mg.hr.radiation when she was 51 years old. She complained of post-menopausal bleeding at age 66 and was diagnosed by endometrial cytology as having clear cell carcinoma of the endometrium. Total abdominal hysterectomy, bilateral salpingo-oophorectomy and omentectomy were performed. The clinical stage of the endometrial cancer was Ib. She is alive after 2 years with no evidence of disease. Endometrial cytology revealed several adenocarcinoma cells in small clusters. The shape of the nuclei was somewhat irregular, the chromatin pattern was fine granular, and single or multiple nucleoli were seen. The diameter of these nuclei ranged from 10 to 30 {mu}m. The cytoplasm was pale green or vacuolated. The volume of the cytoplasm varied from scanty to abundant. These findings suggested clear cell carcinoma. Histopathologically, an irregular shaped polypoid tumor, 3 x 1.5 cm in size, was located on the lower anterior wall of the uterine corpus. The tumor was a clear cell carcinoma showing a solid and papillary pattern. A hobnail pattern was not observed. The cytoplasm was clear and abundant, and PAS-positive granules digestible by diastase were seen. These 2 cancers had different pathological features and their immunohistochemical reactivities for CEA and keratin were also different. The patient was regarded as having a rare heterochronous double cancer consisting of squamous cell carcinoma of the cervix and clear cell carcinoma of the endometrium. (author).

    Of 47 elderly patients treated by simple radiotherapeutic techniques for basal cell carcinomas, 12 are alive and free of disease more than 10 years after treatment. They were asked to rate their perception of the current cosmetic appearance of their lesions on a scale consisting of: excellent, very good, good, mediocre, and poor. Six of the 12 rated their cosmetic appearance as excellent, three considered it very good, and three called it good. Despite undeniable objective deterioration of the cosmetic appearance of irradiated basal cell carcinomas, patients appear to be pleased with the results. (author)

    The brain is a common site of metastases in small-cell carcinoma of the lung. Prophylactic brain irradiation with doses of 4000-4500 rads in 3-4 weeks appears to decrease the occurrence of brain metastases although it does not prevent this completely. In a group of patients with small-cell carcinoma of the lung and without evidence of brain metastases, the authors review the site and extent of the primary, the methods of treatment, the techniques of brain irradiation, and the relapses rate in relation to the status of the primary and the rate of brain metastases in another group without prophylactic brain irradiation. They further attempt to investigate combined modalities of treatment which would prolong life and prevent neurological complications in the small number of long survivors with small-cell carcinoma of the lung.

    To investigate differences between Hispanics and non-Hispanic whites diagnosed with and treated for renal cell carcinoma in an equal access healthcare system. We carried out a retrospective cohort study within the Kaiser Permanente healthcare system using records from renal cell carcinoma cases. Ethnicity was identified as Hispanic or non-Hispanic whites. Patient characteristics, comorbidities, tumor characteristics and treatment were compared. Overall and disease-specific survival was calculated, and a Cox proportion hazard model estimated the association of ethnicity and survival. A total of 2577 patients (2152 non-Hispanic whites, 425 Hispanic) were evaluated. Hispanics were diagnosed at a younger age (59.6 years vs 65.3 years). Clear cell renal cell carcinoma was more prevalent, whereas papillary renal cell carcinoma was less common among Hispanics. Hispanics had a lower American Joint Committee on Cancer stage (I/II vs III/IV) than non-Hispanic whites (67.4% vs 62.2%). Hispanics were found to have a greater frequency of comorbidities, such as chronic kidney disease and diabetes, but were more likely to receive surgery. The presence of metastases, nodal involvement, increased tumor size, non-surgical management, increasing age and Hispanic ethnicity were independent predictors of worse cancer-specific outcome. Within an equal access healthcare system, Hispanics seem to be diagnosed at younger ages, to have greater comorbidities and to present more frequently with clear cell renal cell carcinoma compared with non-Hispanic white patients. Despite lower stage and greater receipt of surgery, Hispanic ethnicity seems to be an independent predictor of mortality. Further work is necessary to confirm these findings. © 2017 The Japanese Urological Association.

    The evaluation of a cancer patient can be affected by many factors. Cancer patients often have other diseases or medical conditions in addition to their cancer. These conditions are referred to as comorbidities. They can influence the treatment option, the rate of complications, the outcome, and can confound the survival analysis. It was the aim of this study to measure comorbidities in patients with laryngeal squamous cell carcinoma. Ninety adult patients treated for newly diagnosed laryngeal squamous cell carcinoma were studied. We measured comorbid illness applying the following validated scales: the Cumulative Illness Rating Scale (CIRS), the Kaplan-Feinstein Classification (KFC), the Charlson index, the Index of Coexistent Disease (ICED), the Adult Comorbidity Evaluation-27 (ACE-27), the Alcohol-Tobacco-Related Comorbidities Index (ATC), and the Washington University Head and Neck Comorbidity Index (WUHNCI). Survival analysis was performed using the Kaplan-Meier method (with the log-rank test value being used to compare groups). The Cox proportional hazards model was chosen to identify independent prognostic factors. The mean age was 62.3 years. The majority of patients (36.7%) had early tumors. Forty patients were treated by surgery only, while the remaining 49 patients also received postoperative radiation therapy. Only 5 patients (5.6%) were lost to follow-up. Median follow-up time was 42.5 months. The 4-year overall survival was 63%. There was a statistically significant difference between survival rates according to clinical stage (CS I 87.3%, CS II 48.9%, CS III 74.7%, CS IV 23.9%; p KFC (p = 0.001), and ICED (p = 0.010). However, in the multivariate analysis, only CIRS and TNM staging were identified as independent prognostic factors. The comorbidity is an independent prognostic factor in patients with surgically treated laryngeal cancer. In the univariate analysis, all indexes were able to stratify patients. However, in the multiple analysis, only the

    Full Text Available Abstract Small cell carcinoma of the bladder (SCCB is rare, highly aggressive and diagnosed mainly at advanced stages. Hematuria is the main symptom of this malignancy. The origin of the disease is unknown; however the multipotent stem cell theory applies best to this case. Histology and immunohistochemistry shows a tumour which is indistinguishable from small cell lung carcinoma (SCLC. Coexistence of SCCB with other types of carcinoma is common. The staging system used is the TNM-staging of bladder transitional cell carcinoma. The treatment is extrapolated from that of SCLC. However, many patients with SCCB undergo radical resection which is rarely performed in SCLC. Patients with surgically resectable disease ( or = cT4bN+M+ should be managed with palliative chemotherapy based on neuroendocrine type regimens comprising a platinum drug (cisplatin in fit patients. The prognosis of the disease is poor mainly in the case of pure small cell carcinoma. Other research programs are needed to improve the outcome of SCCB.

    2013-01-01

    Merkel cell carcinoma (MCC) is a rare, aggressive neuroendocrine tumor of the skin with a mortality rate of approximately 25% (Peloschek et al., 2010). Accurate assessment of nodal involvement in patients with MCC predicts significantly overall outcome (Smith et al., 2012 and Ortin-Perez et al., 2007). Due to the rarity of this highly aggressive disease, only a few imaging reports on MCC were published, and subsequently still to date no accepted imaging algorithm for MCC is available. For primary staging of MCC, general recommendations have included ultrasonography, chest X-ray CT, and MRI, but recent articles show that the use of sentinel node and FDG-PET/PET-CT is gaining more and more importance

    Purpose: To review the factors that influence outcome and patterns of relapse in patients with cutaneous squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) with perineural infiltration (PNI) without clinical or radiologic features, treated with surgery and radiotherapy. Methods and Materials: Between 1991 and 2004, 222 patients with SCC or BCC with PNI on pathologic examination but without clinical or radiologic PNI features were identified. Charts were reviewed retrospectively and relevant data collected. All patients were treated with curative intent; all had radiotherapy, and most had surgery. The primary endpoint was 5-year relapse-free survival from the time of diagnosis. Results: Patients with SCC did significantly worse than those with BCC (5-year relapse-free survival, 78% vs. 91%; p < 0.01). Squamous cell carcinoma with PNI at recurrence did significantly worse than de novo in terms of 5-year local failure (40% vs. 19%; p < 0.01) and regional relapse (29% vs. 5%; p < 0.01). Depth of invasion was also a significant factor. Of the PNI-specific factors for SCC, focal PNI did significantly better than more-extensive PNI, but involved nerve diameter or presence of PNI at the periphery of the tumor were not significant factors. Conclusions: Radiotherapy in conjunction with surgery offers an acceptable outcome for cutaneous SCC and BCC with PNI. This study suggests that focal PNI is not an adverse feature.

    Metastatic renal cell carcinoma of the nasopharynx, nasal cavity, and paranasal sinuses can be misdiagnosed as primary malignant or benign diseases. A 33-year-old male attended our outpatient clinic complaining of difficulty breathing through the nose, bloody nasal discharge, postnasal drop, snoring, and discharge of phlegm. Endoscopic nasopharyngeal examination showed a vascularized nasopharyngeal mass. Under general anesthesia, multiple punch biopsies were taken from the nasopharynx. Pathologically, the tumor cells had clear cytoplasm and were arranged in a trabecular pattern lined by a layer of endothelial cells. After the initial pathological examination, the pathologist requested more information about the patient's clinical status. A careful history revealed that the patient had undergone left a nephrectomy for a kidney mass diagnosed as renal cell carcinoma 3 years earlier. Subsequently, nasopharyngeal metastatic renal cell carcinoma was diagnosed by immunohistochemical staining with CD10 and vimentin. Radiotherapy was recommended for treatment.

    Science.gov (United States)

    2014-01-01

    Accurate identification of the microscopic risk factors of oral and oropharyngeal (OP) squamous cell carcinomas (SCC) and their morphologic variants is of at most importance, as these generally determine treatment modalities, prognosis and overall patient outcome. The great majority of oral and oropharyngeal squamous cell carcinomas are microscopically described as kerartinizing squamous cell carcinoma (KSCC). They bear certain resemblance to keratinizing stratified squamous epithelium. Tobacco habits and excessive consumption of alcoholic beverages have been considered to be the main etiologic agents in these carcinomas. The tumors occurred in older patients more commonly affected the oral tongue and floor of the mouth with well established morphologic risk factors including tumor grade, pattern of invasion and perineural involvement. Within the last 30 years however, the advent and expanding prevalence of high risk human papillomavirus (HPV) as an important etiologic agent for head and neck squamous cell carcinoma, particularly in the OP, has resulted in a significant change in the established morphologic criteria for risk assessment. The majority of HPV relate carcinomas of the OP are nonkeratinizing squamous cell carcinoma (NKSCC). These tumors are found to be more responsive to treatment with a favorable patient outcome and good prognosis. Consequently, alterations in treatment protocols aimed at de-escalation are currently being evaluated. More recently, other morphologic variants that are HPV positive are reported with increasing frequency in the OP and other head and neck sites. As a result, several clinical and pathologic questions have emerged. Importantly, whether the virus is biologically active in these tumors and involved in their pathogenesis, and second, what are the clinical implications with regard to patient management and outcome in the HPV-related variants. Examples of HPV-related squamous cell carcinoma variants that will be addressed here are

    2012-01-01

    Full Text Available Oral squamous cell carcinomas represent 3% of cancers in men and 2% of cancers in women. More than 90% of oral cancer occurs in people older than 45 years Lesions of gingiva account for approximately 10% of the oral squamous cell carcinomas and may present clinically as an area of ulceration, exophytic mass, or red/white speckled patches. The proximity to the underlying periosteum may invite early bone invasion. Carcinoma of gingiva constitutes an extremely important group of neoplasms as the lesion frequently mimics the reactive and inflammatory conditions affecting the periodontium, delaying the diagnosis and making the prognosis of the patient poorer. A rare case of gingival squamous cell carcinoma has been reported here, in a 40 Year old male patient. Careful recording of the case history and results of clinical examination, radiographic, and laboratory investigations, along with a critical review of similar conditions led to the diagnosis, and treatment was initiated.

    Objectives The aim of this study was to investigate somatic mutations in the D-loop of mitochondrial DNA (mtDNA) and their impact on survival in oral squamous cell carcinoma patients. Materials and Methods Surgical specimen confirmed by pathological examination and corresponding non-cancerous tissues were collected from 120 oral squamous cell carcinoma patients. The sequence in the D-loop of mtDNA from non-cancerous tissues was compared with that from paired cancer samples and any sequence differences were recognized as somatic mutations. Results Somatic mutations in the D-loop of mtDNA were identified in 75 (62.5%) oral squamous cell carcinoma patients and most of them occurred in the poly-C tract. Although there were no significant differences in demographic and tumor-related features between participants with and without somatic mutation, the mutation group had a better survival rate (5 year disease-specific survival rate: 64.0% vs. 43.0%, P = 0.0266). Conclusion Somatic mutation in D-loop of mtDNA was associated with a better survival in oral squamous cell carcinoma patients. PMID:25906372

    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.

    Full Text Available Abstract Background Leptomeningeal carcinomatosis occurs in patients with cancer at the rate of approximately 5%; it develops particularly in patients with breast cancer, lung cancer, melanoma, leukemia, or malignant lymphoma. We describe a rare case of leptomeningeal carcinomatosis in which spinal intradural squamous cell carcinoma with no lesions in the cerebral meninges and leptomeninx, was the primary lesion. Methods A 64-year-old man complained of sacral pain. Although the patient was treated with analgesics, epidural block and nerve root block, sacral pain persisted. Since acute urinary retention occurred, he was operated on. The patient was diagnosed as having an intradural squamous cell carcinoma of unknown origin. Results Since the patient presented with a slightly decreased level of consciousness 2 months after surgery, he was subjected to MRI scanning of the brain and spinal cord, which revealed disseminated lesions in the medulla oblongata. The patient died of pneumonia and sepsis caused by methicillin-resistant Staphylococcus aureus 5 months after surgery. Conclusion We report the first case of a patient with intradural squamous cell carcinoma with unknown origin that developed independently in the sacrum.

    Nevoid Basal Cell Carcinoma Syndrome (NBCCS) is an autosomal-dominant disorder characterized by multiple basal cell carcinomas, jaw cysts, palmar/plantar pits, calcification of the falx cerebri, and spine and rib anomalies. The combination of clinical, imaging, and histological findings is helpful in identifying NBCCS patients. Imaging plays a crucial role in evaluation of these patients. We present a wide variety of clinical and radiological findings characteristic of this disease. (orig.)

    Outcomes of metastatic papillary renal cell carcinoma (pRCC) patients are poorly characterized in the era of targeted therapy. A total of 5474 patients with metastatic renal cell carcinoma (mRCC) in the International mRCC Database Consortium (IMDC) were retrospectively analyzed. Outcomes were...... compared between clear cell (ccRCC; n = 5008) and papillary patients (n = 466), and recorded type I and type II papillary patients (n = 30 and n = 165, respectively). Overall survival (OS), progression-free survival (PFS), and overall response rate (ORR) favored ccRCC over pRCC. OS was 8 months longer...

    Background: Merkel cell carcinoma is a rare tumor that occurs on areas exposed to ultraviolet light. It is usually asymptomatic and it is diagnosed late often. The treatment is surgical, associated with adjuvant radiotherapy. The objective was to present the experience in the management of Merkel cell carcinoma in a reference medical center. Methods: all patients with Merkel cell carcinoma treated at the Instituto de Investigaciones Médico-Biológicas of the Universidad Veracruzana during the period 2008 to 2011 were studied. Sex, age, evolution time, tumor localization, size, metastases and treatment were analyzed. Results: of 3217 patients treated, three cases were Merkel cell carcinoma (0.09 %), their age was 52.1 ± 14.17, male predominance of 66.67 %; the evolution time was of 29.66 ± 35.36 months; the tumour localization was on inguinal region, anterior chest and left arm; the noodle size was of 6.0 ± 5.19 cm; two patients had lymph node metastases. In two cases, resection and lymphadenectomy were performed. They all received radiation therapy and chemotherapy in one case. Histologically the medium variant predominated; immunohistochemistry was positive in the three cases. One patient died ten months after the study was done. Conclusions: our experience is similar with others authors, Merkel cell carcinoma is a rare tumor, usually diagnosed late, and it has poor survival.

    Full Text Available Renal clear cell carcinoma (RCC has different manifestations, including uncommon metastasis and paraneoplastic syndromes. Here we report a rare case of RCC presenting as metastasis to the mandible. A 57-year-old patient with mandibular swelling was referred to the dentist. After necessary evaluations, an incisional biopsy of mandible showed metastatic RCC. The patient was referred to the urologist. The patient underwent right radical nephrectomy. Pathological examination showed clear renal cell carcinoma. Every abnormal bone lesion in the oral cavity should be evaluated carefully and the possibility of a malignant lesion should always be considered.

    Primarily palliative renal embolization is a relatively rare procedure which is indicated in patients with unresectable kidney malignancies and in patients in poor general condition. The aim of this paper was to evaluate the role of primarily palliative transarterial renal embolization for the treatment of inoperable patients with renal cell carcinoma, assessing the indications, safety, and efficacy of this procedure. Seventy-three patients scheduled for palliative embolization between 1998 and 2005 were retrospectively analyzed regarding their medical history, the procedure report, and data from the early postoperative period. Sixty-six of the 73 patients presented with renal cell carcinoma stage IV. The most common indication for embolization was hematuria (34%), followed by flank pain (32%), prophylaxis in stage IV (25%), lack of consent for surgery (7%), and poor general condition (3%). Embolizations were performed under local anesthesia with a mixture of enbucrilate and iodinated oil, with the use of additional embolizing materials in two cases. The procedure eliminated hematuria in 100% of cases and removed the loin pain completely in 72%. Migration of the embolizing material was observed in 10% of cases, and in 4% it resulted in symptomatic occlusion of the lower extremity distal arteries. Postembolic syndrome was noted in 92% of the patients Percutaneous palliative embolization with enbucrilate is a safe and effective method of treating patients with unresectable renal cell carcinoma. The potential effect of the embolization on cancer progression and improvement of survival in these patients still requires prospective investigation.

    Purpose: In 1960 Gorlin and Goltz defined the nevoid basal cell carcinoma syndrome (NBCCS, Gorlin-Goltz Syndrome) as a syndrome comprising multiple basal cell carcinoma, odontogenic keratocysts, and skeletal anomalies. NBCCS is an autosomal dominantly inherited disease with an estimated prevalence of 1:150 000 and diagnosis of this syndrome is often an accidental finding of radiological investigations. The purpose of this study was to report the varied radiological and dermatological manifestations of our patients affected with NBCCS and to present this rare syndrome as a differential diagnosis of skeletal anomalies. Materials and Methods: Between 1994 and 2005 the demographic, clinical, radiological and histological data of 8 patients with NBCCS were retrospectively analyzed. Nevoid basal cell carcinoma syndrome was diagnosed in the event of two major or one major and two minor criteria. The major criteria are more than 2 basal cell carcinoma, odontogenic keratocysts, three or more palmar pits, and calcification of the falx cerebri. Results: Between 1994 and 2005 8 patients (3 females and 5 males) with NBCCS were treated in our departments. The average age at the time of diagnosis of NBCCS was 49.9 years. All patients had a minimum of two major criteria. The major criteria with the most frequency were the basal cell carcinoma (6 patients) and the odontogenic keratocysts (5 patients), followed by the calcification of the falx cerebri and palmoplantar pits (4 patients). There was no gender-related or age-related predilection and only one patient was affected with pain in his fingers which radiologically correlated to small cystic bone lesions (''flame-shaped lucencies'').

    Nevoid basal cell carcinoma syndrome, or basal cell nevus syndrome (Gorlin syndrome), is a rare autosomal dominantly inherited disorder that is characterized by development of basal cell carcinomas from a young age. Other distinguishing clinical features are seen in a majority of patients, and include keratocystic odontogenic tumors (formerly odontogenic keratocysts) as well as dyskeratotic palmar and plantar pitting. A range of skeletal and other developmental abnormalities are also often seen. The disorder is caused by defects in hedgehog signaling which result in constitutive pathway activity and tumor cell proliferation. As sporadic basal cell carcinomas also commonly harbor hedgehog pathway aberrations, therapeutic agents targeting key signaling constituents have been developed and tested against advanced sporadically occurring tumors or syndromic disease, leading in 2013 to FDA approval of the first hedgehog pathway-targeted small molecule, vismodegib. The elucidation of the molecular pathogenesis of nevoid basal cell carcinoma syndrome has resulted in further understanding of the most common human malignancy.

    Objective: To investigate the clinical characteristics and treatment of primary parotid squamous cell carcinoma through 16 patients. Methods: Sixteen such patients treated in our hospital from 1984 to 2005 were analyzed retrospectively. There were T1 2 patients, T2 and T3 5 patients each and T4 4. Ten patients had NO, and 6 N + lesions. Six patients were treated by monotherapy, ie-mono group (surgery alone or radiotherapy alone), the other 10 patients by surgery combined with postoperative radiotherapy. Results: The overall neck metastastic lymph nodes was observed in 12 patients (75%). The 3- and 5-year local control, overall survival and disease-free survival for the whole group was 45% and 30%, 58% and 58%; 36% and 27%, respectively. The 5-year survival for T1-T2 and T3-T4 patients was 100% and 29% (χ 2 =4.50, P=0.034), respectively. The 3-year overall survival of NO and N + patients was 80%, and 20% (χ 2 =8.70, P=0.003), with a disease-free survival of 54% and 0 (χ 2 =9.83, P=0.002), respectively. Conclusions: The choice of suitable treatment for locally advanced primary parotid squamous cell carcinoma is surgery plus postoperative radiotherapy. Prophylactic ipsilateral neck irradiation is necessary e- ven for N0 patients for the sake of high risk of neck node metastasis. (authors)

    2016-09-01

    Full Text Available Nevoid basal cell carcinoma syndrome (BCNS is an autosomal dominant inherited disorder. Multiple organ systems may be affected in this syndrome including abnormalities of the skin, skeletal system, genitourinary system and central nevus system. In this report, we present a case of Nevoid basal cell carcinoma syndrome in a 26-year-old male patient. The patient had multiple odontogenic keratocyst in the posterior of mandible, syndactyly in both hand and bifid rib. After enucleation and curettage, he was followed for two years. A number of both clinical and radiological criteria are used to diagnose this syndrome. Basal cell carcinoma syndrome is diagnosed with two major criteria or one major and two minor criteria. We must suspect this disorder in young patients with multiple odontogenic keratocyst and dental abnormalities whether related or not with other clinical manifestations or familial history.

    The use of prosthetic implants for breast augmentation has become commonplace. Although implants do not increase the risk of conventional mammary carcinoma, they are rarely associated with anaplastic large cell lymphoma. We report 2 cases of breast implant capsule-associated squamous cell carcinoma with poor clinical outcomes. Both patients (56-year-old woman and 81-year-old woman) had long-standing implants (>25 years) and presented with acute unilateral breast enlargement. In both cases, squamous cell carcinoma arose in (focally dysplastic) squamous epithelium-lined breast implant capsules and widely invaded surrounding breast parenchyma or chest wall. Neither patient had evidence of a primary mammary carcinoma or squamous cell carcinoma at any other anatomic site. Within 1 year, one patient developed extensive, treatment-refractory, locoregional soft tissue metastasis, and the second patient developed hepatic and soft tissue metastases and died of disease. There are 2 prior reported cases of implant-associated squamous cell carcinoma in the plastic surgery literature; one provides no pathologic staging or outcome information, and the second case was a capsule-confined squamous cell carcinoma. Together, all 4 cases share notable commonalities: the patients had long-standing breast implants and presented with acute unilateral breast pain and enlargement secondary to tumors arising on the posterior aspect of squamous epithelialized implant capsules. Because of both its rarity and its unusual clinical presentation, implant capsule-associated squamous cell carcinoma may be underrecognized. The aggressive behavior of the tumors in this series underscores the importance of excluding malignancy in patients with long-standing breast implants who present with acute unilateral breast pain and enlargement.

    Collision tumor is an extremely rare tumor which defined as the concrescence of two distinct primaries neoplasms. We report here a case of collision tumor at lower third esophagus composed of small cell type neuroendocrine carcinoma (NEC), which is an very rare, highly aggressive and poorly prognostic carcinoma and squamous cell carcinoma (SqCC). In our case, pathologically, the small cell carcinoma display the characteristic of small, round, ovoid or spindle-shaped tumor cells with scant cytoplasm, which colliding with a moderately differentiated squamous cell carcinoma. Immunohistochemical staining demonstrated positive activities for CD56, synaptophysin, 34βE12, CK 5/6, ki-67 (70%-80%), but negative for CD99, chromogranin A, and TTF-1. Accurate diagnosis was made base on these findings. PMID:24817981

    Full Text Available Abstract Background Merkel cell polyomavirus (MCPyV was identified originally in Merkel cell carcinoma (MCC, a rare form of human skin neuroendocrine carcinoma. Evidence of MCPyV existence in other forms of malignancy such as cutaneous squamous cell carcinomas (SCCs is growing. Cervical cancers became the focus of our interest in searching for potentially MCPyV-related tumors because: (i the major histological type of cervical cancer is the SCC; (ii the uterine cervix is a common site of neuroendocrine carcinomas histologically similar to MCCs; and (iii MCPyV might be transmitted during sexual interaction as demonstrated for human papillomavirus (HPV. In this study, we aimed to clarify the possible presence of MCPyV in cervical SCCs from Japanese patients. Cervical adenocarcinomas (ACs were also studied. Results Formalin-fixed paraffin-embedded tissue samples from 48 cervical SCCs and 16 cervical ACs were examined for the presence of the MCPyV genome by polymerase chain reaction (PCR and sequencing analyses. PCR analysis revealed that 9/48 cervical SCCs (19% and 4/16 cervical ACs (25% were positive for MCPyV DNA. MCPyV-specific PCR products were sequenced to compare them with reference sequences. The nucleotide sequences in the MCPyV large T (LT-sequenced region were the same among MCPyV-positive cervical SCCs and AC. Conversely, in the MCPyV viral protein 1 (VP1-sequenced region, two cervical SCCs and three cervical ACs showed several nucleotide substitutions, of which three caused amino acid substitutions. These sequencing results suggested that three MCPyV variants of the VP1 were identified in our cases. Immunohistochemistry showed that the LT antigen was expressed in tumor cells in MCPyV-positive samples. Genotyping of human HPV in the MCPyV-positive samples revealed that infected HPVs were HPV types 16, 31 and 58 for SCCs and HPV types 16 and 18 for ACs. Conclusions This study provides the first observation that MCPyV coexists in a subset

    Full Text Available Introduction. The incidence of gallbladder cancer presenting with acute cholecystitis is 2.3%, squamous cell carcinoma is rarely seen, and overlap of acute cholecystitis and squamous cell carcinoma is a very rare condition in the literature. Presentation of Case. A 75-year-old woman was admitted to emergency service with a pain in the right upper quadrant, nausea, and vomiting. The patient was considered as having acute cholecystitis. During the exploration because Hartman’s pouch was not dissected, it was adhered to the cystic duct and had fibrotic adhesion. It could not be understood whether this adhesion was a tumor or a fibrotic tumor and thus we performed cholecystectomy with a 1 cm resection of the choledochus. Pathological examination revealed the presence of (R0, T1 N0 M0 squamous cell carcinoma with clean resection borders and there was no in tumor five dissected lymph nodes. The patient has been followed up for about two years and no clinical problem has been observed throughout the follow-up. Discussion. Acute cholecystitis with gallstones may overlap with gallbladder cancer and generally presents nonspecific symptoms. No additional imaging techniques were performed since no clinical sign except for the wall thickening was detected and no suspected malignancy such as mass was detected on USG. Squamous cell carcinoma of the gallbladder shows poor diagnosis, but since its overlap with cholecystitis presents early symptoms and thus leads to early diagnosis and effective treatment, the localization of the carcinoma is of prime importance. Conclusion. Gallbladder cancer should be kept in mind in elderly patients with acute cholecystitis.

    Patients with metastatic Merkel cell carcinoma are treated similarly to small cell lung cancer (SCLC). Poly ADP-ribose polymerase-1 (PARP1) is overexpressed in SCLC and response to PARP inhibitors have been reported in patients with SCLC. Our study explores PARP as a therapeutic target in Merkel cell carcinoma. We evaluated PARP1 expression and Merkel cell polyomavirus (MCPyV) in 19 patients with Merkel cell carcinoma. Target exome-sequencing was performed in 14 samples. Sensitivity to olaparib was tested in 4 Merkel cell carcinoma cell lines. Most Merkel cell carcinomas (74%) express PARP1 at high levels. Mutations in DNA-damage repair genes were identified in 9 samples (64%), occurred exclusively in head neck primaries, and correlated with TP53/RB1 mutations. The TP53/RB1 mutations were more frequent in MCPyV-negative tumors. Sensitivity to olaparib was seen in the Merkel cell carcinoma line with highest PARP1 expression. Based on PARP1 overexpression, DNA-damage repair gene mutations, platinum sensitivity, and activity of olaparib in a Merkel cell carcinoma line, clinical trials with PARP inhibitors are warranted in Merkel cell carcinoma. © 2018 Wiley Periodicals, Inc.

    Since the first description of the Merkel cell carcinoma by Cyril Toker in 1972, the number of studies has significantly increased over the last 4 decades. In this review, we will illustrate the historical background of the Merkel cell carcinoma beginning with the 19th century, the first description of the Merkel cell to the finding of the CK20 as a highly specific diagnostic marker and finally to the recently detected Merkel cell polyoma virus (MCPyV). Moreover, we will highlight the beginning of adjuvant therapeutic regimens with radiotherapy and chemotherapy and discuss the diagnostic work-up including imaging and histology of patients with Merkel cell carcinoma. Another very rapidly growing and interesting field of research is the development of patients' specific and tailored targeted therapy, in particular in patients with distant metastatic disease.

    Full Text Available Adenoid cystic carcinoma of uterine cervix is a rare tumor. Its origin is debatable. It has a high incidence in postmenopausal women but rarely can develop in patients under 40. An association with squamous cell carcinoma has been described. We report a case of adenoid cystic carcinoma of the endocervical canal with foci of squamous cell carcinoma in a 34-year-old suffering from menorrhagia associated with blood-stained vaginal discharge. Per vaginum and per speculum examination revealed a growth. Cervical biopsy showed bits of tissue, suggesting adenoid cystic carcinoma. Patient was operated upon and uterus with cervix sent for histopathological examination. We report this case because of its rarity, particularly in young patients, with description of illustrative pathology and discussion on the histological diagnosis.

    A total of 98 patients with malignant tumors of the tonsil (Squamous cell carcinoma, 34 patients, Non-Hodgkin's lymphoma, 64 patients) werw treated with radiation therapy between 1962 and 1979 at the National Cancer Center Hospital. All were staged by the TNM system, using UICC Classification 1978. With regard to stage distribution, Stage III is most frequent (47.1 %) in squamous cell carcinoma, Stage IV is most frequent (48.4 %) in Non-Hodgkin's lymphoma. Much more advanced cases were included in Non-Hodgkin's lymphoma. Five year survival rate for patients with squamous cell carcinoma and Non-Hodgkin's lymphoma were 49 % and 62 %, respectively. 50 % survival months with squamous cell carcinoma and Non-Hodgkin's lymphoma were 58.7 months and 195.5 months, respectively. Better prognosis was observed in Non-Hodgkin's lymphoma than squamous cell cacinoma. (author)

    Full Text Available Abstract Background Our objective was to test a brief, symptom index for advanced renal cell carcinoma, a disease affecting over 38,000 Americans each year and often diagnosed in late stages. Methods We conducted secondary data analyses on patient-reported outcomes of 209 metastatic renal cell carcinoma patients participating in a Phase III clinical trial. Patient-reported outcomes, obtained from the FACT-Biological Response Modifier (FACT-BRM scale, were available at baseline, 2, and 8 weeks. We analyzed data from eight FACT-BRM items previously identified by clinical experts to represent the most important symptoms of advanced renal cell carcinoma. Items comprising this index assess nausea, pain, appetite, perceived sickness, fatigue and weakness, with higher scores indicating fewer symptoms. We determined reliability and validity of the index and estimated a minimally important difference. Results The index had excellent internal reliability at all three time points (alphas ≥ 0.83. Baseline scores were able to discriminate patients across Karnofsky performance status, number of metastatic sites, and risk group categories (ps Conclusion The 8-item index of patient-reported symptoms of renal cell carcinoma appears to be a psychometrically sound measure. It is a brief, reliable, and valid measure that can easily be adapted for use in clinical trials and observational studies.

    To determine the computed tomographic (CT) characteristics of nonfunctioning islet cell carcinoma of the pancreas, the CT scans of 27 patients with that disease were reviewed. The pancreatic tumor was identified as a mass in 26 patients (96%) Of the 25 tumors evaluated with contrast enhancement, 20 became partially diffusely hyperdense relative to nearby normal pancreatic tissue. Hepatic metastases were identified in 15 patients (56%), regional lymphadenopathy in 10 (37%), atrophy of the gland proximal to the tumor in six (22%), dilatation of the biliary ducts in five (19%), and dilatation of the pancreatic duct in four (15%). The CT appearances of the nonfunctioning islet cell tumors were compared with those of 100 ordinary (ductal) pancreatic adenocarcinomas. Although the two types of tumors were sometimes indistinguishable, features found to be more characteristic of islet cell carcinoma included a pancreatic mass of unusually large size, calcification within the tumor, and contrast enhancement of either the primary tumor or hepatic metastases. Involvement of the celiac axis or proximal superior mesenteric artery was limited to ductal carcinoma.

    Merkel cell carcinoma is a rare, aggressive neurocutaneous malignancy. This study investigated whether patients with Merkel cell carcinoma in the head and neck had poorer outcomes than patients with Merkel cell carcinoma located elsewhere. A retrospective study was performed of patients with Merkel cell carcinoma treated at the Jewish General Hospital in Montréal, Canada, from 1993 to 2013. Associations between clinicopathological characteristics and disease-free and disease-specific survival rates were examined according to the Kaplan-Meier method. Twenty-seven patients were identified. Although basic clinicopathological characteristics and treatments were similar between head and neck and non-head and neck Merkel cell carcinoma groups, disease-free and disease-specific survival rates were significantly lower in the head and neck Merkel cell carcinoma group (log-rank test; p = 0.043 and p = 0.001, respectively). Mortality was mainly due to distant metastasis. Patients with head and neck Merkel cell carcinoma had poorer survival rates than patients with non-head and neck Merkel cell carcinoma in our study. The tendency to obtain close margins, a less predictable metastatic pattern, and/or intrinsic tumour factors related to the head and neck may explain this discrepancy.

At this stage, palliative therapeutic options including nonspecific cytotoxic drugs, targeted therapy, or immunotherapy can be utilized. In 2016, immunotherapy was approved in Europe for squamous cell carcinoma and adenocarcinoma. Moreover, afatinib was also approved as second-line therapy for squamous cell carcinoma. Case report: This article presents a case of a 76-year-old male with squamous cell carcinoma who received nab-paclitaxel as first-line therapy, and his treatment was switched to the tyrosine kinase inhibitor afatinib (40 mg after disease progression with left lung atelectasis. After receiving afatinib for only 28 days, the atelectasis resolved. No adverse effects were observed from the afatinib therapy. Discussion: In this case, afatinib 40 mg proved to be an effective alternative treatment for an elderly patient. Treatment choice should be based on the performance status of the patient, cost-effectiveness, and drug treatment guidelines. Keywords: lung cancer, EGFR, afatinib

    We initially proposed a useful and novel prognostic model, named CCS [Combination of c-reactive protein (CRP) and squamous cell carcinoma antigen (SCC)], for predicting the postoperative survival in patients with esophageal squamous cell carcinoma (ESCC). Two hundred and fifty-two patients with resectable ESCC were included in this retrospective study. A logistic regression was performed and yielded a logistic equation. The CCS was calculated by the combined CRP and SCC. The optimal cut-off value for CCS was evaluated by X-tile program. Univariate and multivariate analyses were used to evaluate the predictive factors. In addition, a novel nomogram model was also performed to predict the prognosis for patients with ESCC. In the current study, CCS was calculated as CRP+6.33 SCC according to the logistic equation. The optimal cut-off value was 15.8 for CCS according to the X-tile program. Kaplan-Meier analyses demonstrated that high CCS group had a significantly poor 5-year cancer-specific survival (CSS) than low CCS group (10.3% vs. 47.3%, P <0.001). According to multivariate analyses, CCS ( P =0.004), but not CRP ( P =0.466) or SCC ( P =0.926), was an independent prognostic factor. A nomogram could be more accuracy for CSS (Harrell's c-index: 0.70). The CCS is a usefull and independent predictive factor in patients with ESCC.

    FBXW7 (F-box and WD repeat domain containing-7) is a tumor suppressor protein that regulates the degradation of various oncoproteins in several malignancies. However, limited information is available regarding FBXW7 expression in oral squamous cell carcinoma. Therefore, this study aimed to determine the clinical significance of FBXW7 expression in oral squamous cell carcinoma. The FBXW7 expression patterns in oral squamous cell carcinoma and adjacent normal tissues from 15 patients who underwent radical resection were evaluated using quantitative real-time polymerase chain reaction and immunohistochemical staining. In addition, immunohistochemistry was performed using paraffin-embedded sections from biopsy specimens obtained from 110 patients with oral squamous cell carcinoma who underwent surgery after 5 fluorouracil-based chemoradiotherapy. The associations of FBXW7 expression with various clinicopathological features and prognosis were evaluated in these patients. As a results, in the 15 matched samples, the FBXW7 expression was significantly decreased in the oral squamous cell carcinoma tissues compared to that in the adjacent normal tissues. In the clinicopathological analysis, compared to high protein expression, low FBXW7 expression was found to significantly associate with a poor histological response to preoperative chemoradiotherapy. Kaplan-Meier curve analysis revealed that low FBXW7 expression was significantly associated with a poor prognosis, and FBXW7 expression was found to be an independent predictor of overall survival in the multivariate analysis. Our results suggest that FBXW7 may function as a tumor suppressor protein in oral squamous cell carcinoma. In addition, FBXW7 could be a potential biomarker for predicting not only the clinical response to chemoradiotherapy but also overall survival in patients with oral squamous cell carcinoma.

    Avelumab is a promising new therapeutic agent for patients with metastatic Merkel cell carcinoma, a rare and aggressive type of neuroendocrine tumor of the skin. Until the recent approval of avelumab (Bavencio), no therapies were approved by the U.S. Food and Drug Administration for the treatment of metastatic Merkel cell carcinoma. In a recent trial, avelumab, an anti-programmed death ligand-1 antibody, demonstrated an objective response in 28 of 88 patients (31.8% [95.9% CI, 21.9-43.1]) with advanced, chemotherapy-refractory Merkel cell carcinoma. Overall, avelumab was well tolerated at a dose of 10 mg/kg administered intravenously every 2 weeks. Serious treatment-related adverse events were reported in 5 patients (6%), but no grade 4 adverse events or treatment-related deaths were reported. Preliminary data evaluating avelumab in chemotherapy-naive patients is also encouraging. Copyright 2017 Clarivate Analytics.

    Ultraviolet light (UV) is an important risk factor for cutaneous basal cell carcinoma, cutaneous squamous cell carcinoma and cutaneous melanoma of the skin. These cancers most commonly affect persons with fair skin and blue eyes who sunburn rather than suntan. However, each of these cancers appears to be associated with a different pattern of UV exposure and to be mediated by different intracellular molecular pathways.Some melanocortin 1 receptor (MC1R) gene variants play a direct role in the pathogenesis of cutaneous basal cell carcinoma, cutaneous squamous cell carcinoma and cutaneous melanoma apart from their role in determining a cancer-prone pigmentory phenotype (fair skin, red hair, blue eyes) through their interactions with other genes regulating immuno-inflammatory responses, DNA repair or apoptosis.In this short review we focus on the aetiological role of UV in cutaneous basal cell carcinoma, cutaneous squamous cell carcinoma and cutaneous melanoma of the skin, and on some associated biopathological events.

    We aimed to evaluate the feasibility and reliability of brush cytology in the biomarker expression profiling of oral squamous cell carcinomas within the concept of theranostics, and to correlate this biomarker profile with patient measurable outcomes. Markers representative of prognostic gene expression changes in oral squamous cell carcinoma was selected. These markers were also selected to involve pathways for which commercially available or investigational agents exist for clinical application. A set of 7 markers were analysed by immunocytochemistry on the archival primary tumour material of 99 oral squamous cell carcinoma patients. We confirmed the feasibility of the technique for the expression profiling of oral squamous cell carcinomas. Furthermore, our results affirm the prognostic significance of the epidermal growth factor receptor (EGFR) family and the angiogenic pathway in oral squamous cell carcinoma, confirming their interest for targeted therapy. Brush cytology appears feasible and applicable for the expression profiling of oral squamous cell carcinoma within the concept of theranostics, according to sample availability.

    Objective: To evaluate the value of lymphoscintigraphy for cervical sentinel lymph node (SLN) detection in patients with oral squamous cell carcinoma. Methods: Twenty-one patients with clinically N 0 oral squamous carcinoma underwent preoperative lymphoscintigraphy and intraoperative methylene blue location. The results were compared with pathological findings. Results: 1) The sensitivity of lymphoscintigraphy for detecting SLN was 100%(21/21), and methylene blue was 85% (17/20). 2)Both SLN biopsy and cervical ablative dissection confirmed that 33.3% (7/21) patients were with cervical lymph node metastasis. Fourteen non-metastatic SLNs comfirmed by biopsy were also proved with the findings of neck dissection, and the specificity was 100%. Conclusion: Lymphoscintigraphy can detect the cervical SLN and accurately predict cervical lymph node metastasis in patients with oral squamous cell carcinoma.(authors)

    The clear evidence that tumor-infiltrating lymphocytes (TIL) exists in the tumor microenvironment raises the question why renal cell carcinoma (RCC) progresses. Numerous studies support the implication of CD4(+)CD25(high) regulatory T (Treg) cells in RCC development. We aimed in this study to characterize the phenotype and function of circulating and intratumoral Treg cells of RCC patient in order to evaluate their implication in the inhibition of the local antitumor immune response. Our results demonstrate that the proportion of Treg in TIL was, in average, similar to that found in circulating CD4(+) T cells of patients or healthy donors. However, intratumoral Treg exhibit a marked different phenotype when compared with the autologous circulating Treg. A higher CD25 mean level, HLA-DR, Fas, and GITR, and a lower CD45RA expression were observed in intratumoral Treg, suggesting therefore that these cells are effector in the tumor microenvironment. Additionally, intratumoral Treg showed a higher inhibitory function on autologous CD4(+)CD25(-) T cells when compared with circulating Treg that may be explained by an overexpression of FoxP3 transcription factor. These findings suggest that intratumoral Treg could be major actors in the impairment of local antitumor immune response for RCC patients.

    Hürthle cell carcinoma (HCC) is an uncommon thyroid cancer historically considered to be a variant of follicular thyroid carcinoma (FTC). The aim of this study was to assess the differences between these groups in terms of clinical factors and prognoses. A total of 230 patients (153 with FTC and 77 with HCC) with a median follow-up of 13.4 years were studied. The different characteristics were compared using SPSS version 20 statistical software. Patients with HCC were older (57.3±13.8 years vs. 44.6±15.2 years; P<.001). More advanced TNM stages were also seen in patients with HCC and a greater trend to distant metastases were also seen in patients with HCC (7.8% vs. 2.7%, P=.078). The persistence/recurrence rate at the end of follow-up was higher in patients with HCC (13% vs. 3.9%, P=.011). However, in a multivariate analysis, only age (hazard ratio [HR] 1.10, confidence interval [CI] 1.04-1.17; P=.001), size (HR 1.43, CI 1.05-1.94; P=.021), and histological subtype (HR 9.79, CI 2.35-40.81; P=.002), but not presence of HCC, were significantly associated to prognosis. HCC is diagnosed in older patients and in more advanced stages as compared to FTC. However, when age, size, and histological subtype are similar, disease-free survival is also similar in both groups.

    Merkel cell carcinoma is a rare cutaneous, aggressive tumor. Although it shares many neuroendocrine features with small cell lung carcinoma, it has only occasionally been reported with paraneoplastic neurological syndromes. A healthy 67-year-old man developed acute ataxia, vertigo, and nausea. Subsequently he also developed dysarthria, diplopia, xerostomia, fatigability and progressive anorexia. He underwent a full diagnostic workup and was found to have a high titer of voltage-gated calcium channel antibodies in serum and cerebrospinal fluid, neurophysiological findings compatible with Lambert-Eaton myasthenia and neurological signs compatible with cerebellar degeneration. A positron emission tomography study revealed a hypermetabolic lesion in the axilla, subsequently biopsied and consistent with Merkel cell carcinoma. In most previous reports, neurological symptoms preceded the Merkel cell carcinoma diagnosis, and the primary localization was in lymph nodes. This tumor should be considered in patients with paraneoplastic syndrome, and particularly Lambert-Eaton myasthenia after exclusion of small cell lung carcinoma.

    The aim of the study is to determine the levels of E-cadherin, vimentin expression in tumor tissues from patients with oral squamous cell carcinoma (OSCC), and the relationship between the expression of E-cadherin, vimentin and epithelial-mesenchymal transition, in order to explore its values for predicting the invasion and metastasis of oral squamous cell carcinoma, short survival of patients in many types of cancer. E-cadherin and vimentin expression of 10 benign and 42 OSCC tumor tissues was examined by immunohistochemical staining. E-cadherin is positively expressed in normal oral mucosa epithelium, but vimentin expression is not found in normal oral mucosa epithelia; the E-cadherin and vimentin were expressed in 26 of 42 (61.9%) and 16 of 42 (38.1%), respectively. No statistically difference was found for E-cadherin and vimentin expression in patients with different age, gender and tumor location, E-cadherin and vimentin expression was significantly associated with lymph node metastasis and tissue location (P oral squamous cell carcinoma for E-cadherin and vimentin positive expression (P oral squamous cell carcinoma. Our study preliminarily confirmed that EMT phenomenon is existed during the development of oral squamous cell carcinoma. Co-evaluation of E-cadherin and vimentin might be a valuable tool for predicting OSCC patient outcome. PMID:26045832

    Squamous cell oesophageal carcinoma is the most common carcinoma of the oesophagus worldwide. The tumour stage as most important prognostic factor determines the clinical management. Aim of this study was to evaluate the value of FDG-PET 1. in imaging the primary tumour and 2. in N- and M-staging of squamous cell oesophogeal carcinoma. Patients, methods: in 20 patients with histological proven squamous cell carcinoma of the upper and middle oesophagus, FDG-PET was performed in standard technique prior to therapy. FDG uptake in the primary was determined by calculation of the SUVmax. NM-staging due to PET findings was performed as designated by the AJCC/UICC group classification and was compared with pathological and clinically based staging. Sensitivities, specificities and accuracies were calculated. Results: in 19 of 20 patients, primary squamous cell oesopohageal carcinoma was detected by FDG-PET findings with a maximum SUV of 12.5 (mean) ± 5.1 (median 11.5; range 4.8-23.8). One carcinoma in situ was missed. The sensitivity of FDG-PET in imaging the primary tumour was 96%. The sensitivities, specificities and accuracies were 20%, 100%, 58% for N-staging, and 60%, 86% and 93% for M-staging. PET findings caused changes of therapy in 5% (1 patient). Conclusions: FDG-PET was excellent in imaging the primary of squamous cell oesophageal carcinoma in stage T1-T4 and was efficient in M-staging. The low sensitivity in N-staging is of inferior clinical importance. The efficacy of FDG-PET seems to be not significantly be influenced by the histological subtype of oesophageal carcinoma. (orig.)

    This work consists of a retrospective definition of disease courses of 859 patients with lung tumors and the definition of the survival curves in their dependence on histology, radiation dose and sex. With 721 larger-celled bronchial carcinomas the ratio of men to women was 12:1. The age peak lay between 60 and 70 years. The one/five year survival rate of all included larger-celled bronchial carcinomas (n=701) was, independent from the therapy form, 35.7, resp. 4.78%. The one year/five year survival rates were for the squamous epithelia 31.08/0.58%, for the undifferentiated carcinomas 25.34/3.41%, and for the lung tumors without histology 35.4/5.14%. Lobectomized patients with squamous epithelium carcinoma had in comparison to pneumonectomized patients a clearly higher survival chance. A clearly sex-dependent predisposition for a certain type of carcinoma was not present. (TRV) [de

    High-dose interleukin-2 (HD IL-2) is used in the treatment of metastatic renal cell carcinoma (mRCC) and has an overall response rate (ORR) of 12-20% and a complete response rate (CR) of 8% in unselected populations with predominantly clear cell type renal cell carcinoma. Nearly 10-15% of patients with renal cell carcinoma exhibit sarcomatoid differentiation, a feature which correlates with a median overall survival (OS) of 9 months and overall poor prognosis. We report a single institution experience with 21 patients with mRCC with sarcomatoid features post-nephrectomy who were treated with HD IL-2. Twenty one patients with mRCC with sarcomatoid features post-nephrectomy who underwent therapy with HD IL-2 were identified at the University of Pittsburgh Medical Center from 2004 to 2016. Baseline patient characteristics, HD IL-2 cycles, time to progression, and subsequent therapies were evaluated. OS and progression-free survival (PFS) in the cohort were calculated using the Kaplan-Meier method. Disease characteristics were evaluated for significance using the Fischer's exact test and Wilcoxon rank sum test. Patients were predominantly Caucasian males with a median age of 54 years. A majority, 86% of these patients, had metastatic disease at time of initial presentation, primarily with lung and lymph node involvement. The ORR and CR with HD IL-2 was 10% and 5%, respectively. Initial localized disease presentation is the only variable that was significantly associated with response to HD IL-2 (p = 0.0158). Number of HD IL-2 doses did not correlate with response with a mean of 16.5 and 15.0 total doses in responders and non-responders, respectively (p = 0.53). Median PFS with HD IL-2 was 7.9 months (95% CI, 5.0-21.3). Median OS was 30.5 months (95% CI 13.3-57.66). Within the subset of patients who had progression on IL-2, median OS was 19.4 months (95% CI, 13.3-35.3). In patients who received second-line therapy, median PFS was 7.9 months (95% CI 2.4-10.2).

    Esophageal squamous cell carcinoma is one of the most common malignant tumors. The oncogene c-MYC is thought to be important in the initiation, promotion, and therapy resistance of cancer. In this study, we aim to investigate the clinicopathologic roles of c-MYC in esophageal squamous cell carcinoma tissue. This study is aimed at discovering and analyzing c-MYC expression in a series of human esophageal tissues. A total of 95 esophageal squamous cell carcinoma samples were analyzed by the western blotting and immunohistochemistry techniques. Then, correlation of c-MYC expression with clinicopathological features of esophageal squamous cell carcinoma patients was statistically analyzed. In most esophageal squamous cell carcinoma cases, the c-MYC expression was positive in tumor tissues. The positive rate of c-MYC expression in tumor tissues was 61.05%, obviously higher than the adjacent normal tissues (8.42%, 8/92) and atypical hyperplasia tissues (19.75%, 16/95). There was a statistical difference among adjacent normal tissues, atypical hyperplasia tissues, and tumor tissues. Overexpression of the c-MYC was detected in 61.05% (58/95) esophageal squamous cell carcinomas, which was significantly correlated with the degree of differentiation (p = 0.004). The positive rate of c-MYC expression was 40.0% in well-differentiated esophageal tissues, with a significantly statistical difference (p = 0.004). The positive rate of c-MYC was 41.5% in T1 + T2 esophageal tissues and 74.1% in T3 + T4 esophageal tissues, with a significantly statistical difference (p = 0.001). The positive rate of c-MYC was 45.0% in I + II esophageal tissues and 72.2% in III + IV esophageal tissues, with a significantly statistical difference (p = 0.011). The c-MYC expression strongly correlated with clinical staging (p = 0.011), differentiation degree (p = 0.004), lymph node metastasis (p = 0.003), and invasion depth (p = 0.001) of patients with esophageal squamous cell carcinoma. The c-MYC was

    Full Text Available Metastatic renal cell carcinoma of the nasopharynx, nasal cavity, and paranasal sinuses can be misdiagnosed as primary malignant or benign diseases. A 33-year-old male attended our outpatient clinic complaining of difficulty breathing through the nose, bloody nasal discharge, postnasal drop, snoring, and discharge of phlegm. Endoscopic nasopharyngeal examination showed a vascularized nasopharyngeal mass. Under general anesthesia, multiple punch biopsies were taken from the nasopharynx. Pathologically, the tumor cells had clear cytoplasm and were arranged in a trabecular pattern lined by a layer of endothelial cells. After the initial pathological examination, the pathologist requested more information about the patient′s clinical status. A careful history revealed that the patient had undergone left a nephrectomy for a kidney mass diagnosed as renal cell carcinoma 3 years earlier. Subsequently, nasopharyngeal metastatic renal cell carcinoma was diagnosed by immunohistochemical staining with CD10 and vimentin. Radiotherapy was recommended for treatment.

    Basal cell carcinoma is the most common form of cancer in humans and comprises the vast majority of skin cancers. It predominantly affects fair-skinned individuals, and its incidence is rapidly increasing. The objective of the study is to identify the epidemiology, its topography and different histological subtypes of basal cell carcinoma in patients with or without Xeroderma Pigmentosum. A cross-sectional descriptive study was conducted at Manipal Teaching Hospital, Pokhara from Jan 2009 to Dec 2016. Ethical approval was taken from MEMG/IRC/GA. The study included patients with a confirmed diagnosis of basal cell carcinoma irrespective of their age and sex. This study showed 77 individuals with 91 biopsies of BCC including 5 cases of Xeroderma Pigmentosum. The predominant histological subtype was nodular with 41 (53.94%) cases, followed by the 14 (18.42%) cases of pigmented and 10 (13.15%) cases baso-squamous subtype. The most frequent sites of involvement were the head and neck, with predominance in the nasal and orbital region. The mean age was 57.68 years but the basal cell carcinoma in cases of Xeroderma Pigmentosum was seen more in younger age groups. There were 43 (55.84 %) male patients and 34 (44.16 %) female patients with a male to female ratio of 1.26:1. Nodular and pigmented varieties were the most frequent subtypes with nose being the commonest site of involvement. Basal cell carcinomas in cases of Xeroderma Pigmentosum were noted in younger age group with multiple lesions.

    Full Text Available Nonmelanoma skin cancers (squamous cell and basal cell carcinomas occur at an epidemic rate in many countries with the worldwide incidence increasing. The sun-exposed head and neck are the most frequent sites for these cancers to arise and in most patients diagnosed with a cutaneous squamous cell carcinoma, local treatment is usually curative. However, a subset is diagnosed with a high-risk cutaneous squamous cell carcinoma. High-risk factors include size (> 2 cm, thickness/depth of invasion (> 4 mm, recurrent lesions, the presence of perineural invasion, location near the parotid gland, and immunosuppression. These patients have a higher risk (> 10–20% of developing metastases to regional lymph nodes (often parotid nodes, and in some cases also of experiencing local morbidity (perineural invasion, based on unfavourable primary lesion and patient factors. Despite treatment, many patients developing metastatic cutaneous squamous cell carcinoma experience mortality and morbidity usually as a consequence of uncontrolled metastatic nodal disease. It is therefore important that clinicians treating nonmelanoma skin cancers have an understanding and awareness of these high-risk patients. The aim of this article is to discuss the factors that define a high-risk patient and to present some of the issues pertinent to their management.

    To evaluate the prognostic significance of urinary collecting system invasion (UCSI) in a large series of patients with clear-cell renal cell carcinoma (RCC). Patients with clear-cell RCC treated with nephrectomy between 2001 and 2010 were reviewed from a prospectively maintained registry. One urological pathologist re-reviewed all slides. Cancer-specific survival was estimated using the Kaplan-Meier method, and associations of UCSI with death from RCC were evaluated using Cox models. Of the 859 patients with clear-cell RCC, 58 (6.8%) had UCSI. At last follow-up, 310 patients had died from RCC at a median of 1.8 years after surgery. The median follow-up for patients alive at last follow-up was 8.2 years. The estimated cancer-specific survival at 10 years after surgery for patients with UCSI was 17%, compared with 60% for patients without UCSI (P system invasion is associated with poor prognosis among patients with clear-cell RCC. If validated, consideration should be given to including UCSI in future staging systems. © 2016 The Authors BJU International © 2016 BJU International Published by John Wiley & Sons Ltd.

    Background Papillary renal cell carcinoma, accounting for 15% of renal cell carcinoma, is a heterogeneous disease consisting of different types of renal cancer, including tumors with indolent, multifocal presentation and solitary tumors with an aggressive, highly lethal phenotype. Little is known about the genetic basis of sporadic papillary renal cell carcinoma; no effective forms of therapy for advanced disease exist. Methods We performed comprehensive molecular characterization utilizing whole-exome sequencing, copy number, mRNA, microRNA, methylation and proteomic analyses of 161 primary papillary renal cell carcinomas. Results Type 1 and Type 2 papillary renal cell carcinomas were found to be different types of renal cancer characterized by specific genetic alterations, with Type 2 further classified into three individual subgroups based on molecular differences that influenced patient survival. MET alterations were associated with Type 1 tumors, whereas Type 2 tumors were characterized by CDKN2A silencing, SETD2 mutations, TFE3 fusions, and increased expression of the NRF2-ARE pathway. A CpG island methylator phenotype (CIMP) was found in a distinct subset of Type 2 papillary renal cell carcinoma characterized by poor survival and mutation of the fumarate hydratase (FH) gene. Conclusions Type 1 and Type 2 papillary renal cell carcinomas are clinically and biologically distinct. Alterations in the MET pathway are associated with Type 1 and activation of the NRF2-ARE pathway with Type 2; CDKN2A loss and CIMP in Type 2 convey a poor prognosis. Furthermore, Type 2 papillary renal cell carcinoma consists of at least 3 subtypes based upon molecular and phenotypic features. PMID:26536169

    The dystrophic form of hereditary epidermo-lysis bullosa is associated with an increased frequency of squamous cell carcinoma. We report a new case. An 18-year-old patient, carrying a Hallopeau Siemens hereditary epidermo-lysis bullosa, presented a subcutaneous nodular lesion, for 1 year that ulcerated and budded with inguinal lymphadenopathy. The histological study ted to the conclusion of a well differentiated squamous cell carcinoma. The patient was treated surgically. Tumor and metastatic lymph nodes were excised. A radiotherapy was decided but the postoperative course was fatal due to an infection and to a deterioration of her general condition. Squamous cell carcinoma frequently occurs on the cicatricial lesion of hereditary epidermo-lysis bullosa and usually affects males with recessive hereditary epidermo-lysis bullosa. Metastases are frequent, precocious and multiple. The treatment may be surgical. The particularities of our observation are the young age of patient and the localization. (author)

    Clinical features of multiple squamous cell carcinoma (SCC) cases within the head and neck that were treated in our department during the recent 10 years are discussed. Multiple SCCs arose in 6.6% of the cases with primary SCC; 67% of the cases had two carcinomas, and 33% had more than three carcinomas. The most common site of the multiple SCCs was the oral cavity (54%). The most frequent interval between treatment of previous carcinoma and diagnosis of subsequent carcinoma was simultaneous, but more than 5 years' interval was observed in 36% of the patients. The most common initial treatment of the carcinoma was irradiation, but the ratio of surgery increased for subsequent carcinomas. Prognosis of the patients with more than three carcinomas was not worse than that of patients with two carcinomas. Therefore, early diagnosis of the subsequent carcinomas based on careful long-term observation in the head and neck is necessary for follow-up of the patients with SCC of the head and neck. Treatment strategies considering the treatment of subsequent carcinomas are needed for the patients with primary head and neck SCC. (author)

    To assess the prognostic importance of serum levels of retinol, retinol-binding protein 4 (RBP4) and vitamin E at the time of diagnosis in patients with renal cell carcinoma (RCC). In this prospective study, in a cohort of 102 renal cell carcinoma patients, relationships between serum levels of the aforementioned markers and recurrence-free survival (RFS), overall survival (OS), as well as cancer-specific survival (CSS), were evaluated. The vitamin A and vitamin E levels were determined by high-performance liquid chromatography (HPLC), while the RBP4 level by enzyme-linked immunosorbent assay (ELISA). The median follow-up period was 39 months. Renal cell carcinoma recurred in 9 patients; 23 patients died with 12 of them from RCC. The preoperative vitamin E level was associated to RFS (p=0.02). We found a significant relationship between OS and the level of RBP4 (p=0.002), retinol (p=0.037) and vitamin E (p=0.007). The CSS period was significantly associated with the level of RBP4 (p=0.0001) and retinol (p=0.0003). Patients with an RBP4 level less than 21.0 mg/l at the time of diagnosis had a 13.5-times higher risk of death due to RCC progression; this risk was up to 7.7-times higher with vitamin A levels under 0.52 mg/l. Low levels of vitamin A, E and RBP4 at the time of RCC diagnosis are associated with a poorer prognosis after surgery. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

    Intracranial metastasis is one of the most morbid manifestations of cancer of the lung. The resulting seizures, headaches, and motor loss severely compromise the individual in the remaining days of his life. The median survival of patients with brain metastasis is only three to four months. Symptoms and signs resulting from brain metastasis are reversible to some degree with cranial irradiation in most patients. Headaches and seizures are most frequently controlled, but motor loss and impaired mentation are less reversible. The high frequency with which small cell carcinoma spreads to the brain has been recognized for many years. For the past decade, prophylactic cranial irradiation has been used widely in conjunction with combination chemotherapy for small cell carcinoma

    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...

    This report represents one case of infiltrative thymoma followed by squamous cell carcinoma of the lungs. A 69-year-old man suffered from infiltrative thymoma which reduced by the radiation therapy. Seven years later its replase and the onset of squamous cell carcinoma were found simultaneously. Infiltrative thymoma metastasized not only to the mediastinum but also to the liver and bronchus. Squamous cell carcinoma developed in the right upper lobe. In spite of chemotherapy against them, the patient died. There are many cases in which infiltrative thymoma is accompanied by squamous cell carcinoma of the lung simultaneously; however, secondary onset of squamous cell carcinoma after the radiation therapy of infiltrative thymoma is rare. Secondary carcinogenesis of this case was considered to be closely related with immunological abnormalities caused by thymoma, effects of radiation, smoking and so on. (author)

    Small cell carcinoma is a rare malignant tumor of the larynx. Since this lesion was first described, only 58 cases have been reported in the literature. Between December 1985 and March 1992, five patients with small cell carcinoma of the larynx were treated at the Hospital de la Santa Creu i Sant Pau in Barcelona, Spain. One patient was treated with radiation therapy alone, three patients with chemotherapy and radiation therapy, and one patient with surgery, chemotherapy and radiation therapy. Local and distant control was achieved in only one patient who was observed for 12 months after radiation therapy. Four patients died, one of local disease without distant metastasis at 6 months following treatment, one of local and distant disease at 53 months after radiation therapy, and two of distant metastasis without local disease at 22 and 36 months following treatment. In spite of the fact that only one of the five patients presented in this series is alive and free of disease 12 months following treatment, recent published information suggests that chemotherapy and radiotherapy are currently the most effective form of therapy for small cell carcinoma of the larynx. 16 Refs

    We report 12 renal cell carcinomas in 6 patients with Von Hippel-Lindau (VHL) disease treated with radiofrequency ablation (RFA). The mean age of the patients was 46 (range 38-53) years (male : 4, female : 2). Computed tomography (CT)-guided transcutaneous RFA was performed under conscious sedation with local anesthetics. The mean size of the tumors was 2.4 (range 0.7-8.1) cm. Nine of the 12 tumors (75%) were locally well controlled. However, 3 tumors in 2 patients developed visceral metastases after RFA. While minimal flank pain, nausea, perinephritic hematoma and lumbago were observed, there was no major complication during or after the procedure. The therapy with CT-guided transcutaneous RFA is efficient and minimal invasive for renal cell carcinoma in patients with VHL, leading to preservation of renal function.

  4. Development of Cerebral Metastasis after Medical and Surgical Treatment of Anal Squamous Cell Carcinoma

    Full Text Available Squamous cell carcinoma of the anus is a relatively uncommon GI malignancy. When it does occur, it metastasizes in only a small minority of patients. Spread of anal squamous cell carcinoma to the brain is exceedingly rare, and has been previously reported only three times in the medical literature. We report the case of a 67 year old male who was diagnosed on presentation with a poorly differentiated anal squamous cell carcinoma that already had a solitary metastasis to the liver. While the tumors were initially responsive to chemoradiotherapy, the patient’s primary and liver lesions recurred. The patient then underwent synchronous abdominoperineal resection for the primary lesion and a liver lobectomy for the metastasis. Soon thereafter, the patient developed focal neurologic symptoms and was found to have an intracranial lesion that on biopsy demonstrated metastatic squamous cell carcinoma. This case highlights the fact that patients with a previous history of anal squamous cell carcinoma can occasionally develop cerebral metastasis. Furthermore, cerebral metastases from anal squamous cell carcinoma portend a dismal prognosis even in the face of aggressive medical and surgical therapy.

    Purpose: To identify prognostic factors for local and distant relapse and perform risk stratification for patients with advanced cervical cancer treated with radiotherapy (RT) alone. Methods and Materials: A total of 1031 patients with Stage IB-IVA squamous cell carcinoma of the cervix treated with full-course RT but without any chemotherapy were included for analysis. Of these, 311 patients with nonbulky Stage IB-IIA disease were designated the reference group and the other 720 patients were the study group. The associations of stage, squamous cell carcinoma antigen (SCC-ag) level, hemoglobin level, age, cell differentiation, and pelvic lymph node status with treatment failure were evaluated. The independent prognostic factors were identified by multivariate analysis. The study group was further stratified into subgroups using combinations of these risk factors. Results: In the study group, independent risk factors for local relapse were advanced stage and age 2, and positive pelvic lymph nodes. The 5-year distant relapse-free survival rate was 83% for patients with bulky Stage IB-IIA and IIB disease, SCC-ag level 2, and positive lymph nodes. Conclusion: The risk of treatment failure in advanced-stage cervical cancer patients treated by RT alone can be more precisely predicted by risk stratification. A certain subgroup of patients had better control than the others. The benefit of treating these relatively low-risk patients with additional treatment such as concurrent chemotherapy should be further evaluated in prospective studies or meta-analyses

    Merkel cell carcinoma is a rare lymphophilic skin tumor of neuroendocrine origin with the potential for rapid progression. Small, localized lesions are diagnosed and treated clinically, but advanced tumors often undergo imaging evaluation. Due to its rarity, radiologists are unaware of evocative imaging features and usually do not consider Merkel cell carcinoma in the differential diagnosis of soft tissue tumors. Appropriate staging is important to determine appropriate treatment and has an impact on patient prognosis. Multimodality imaging is usually needed, and there is no consensus on the optimal imaging strategy. The purpose of this article is to review various aspects of Merkel cell carcinoma imaging and look in detail at how optimal multimodality staging should be carried out. (orig.)

    Radiochemotherapy is the main treatment for patients with squamous cell carcinoma of the anal canal. Anaemia is reported to have adverse effect on survival in cancer patients. The aim of the study was to evaluate the influence of anaemia on radiochemotherapy treatment outcome in patients with squamous cell carcinoma of the anal canal. One hundred consecutive patients with histologically confirmed squamous cell carcinoma of the anal canal were treated radically with 3-dimensional conformal or intensity-modulated radiation therapy followed by brachytherapy or external beam radiotherapy boost and with concurrent mitomycin C and 5-fluorouracil. The influence on survival of pre-treatment, mean on-treatment and end-of-treatment haemoglobin (Hb) concentrations was studied. The 5-year locoregional control, disease free survival, disease specific survival and overall survival rates for all patients were 72%, 71%, 77% and 62%, respectively. In univariate analysis, patients with pre-treatment and end-of-treatment Hb > 120 g/L survived statistically significantly better compared to patients with Hb ≤ 120 g/L. Patients with mean on-treatment Hb > 120 g/L only had statistically significant better locoregional control and overall survival than patients with Hb ≤ 120 g/L. In multivariate analysis, independent prognostic factors were pre-treatment Hb (> 120 g/L vs. ≤ 120 g/L) for overall survival (hazard ratio [HR] = 0.419, 95% confidence interval [CI] = 0.190-0.927, p = 0.032) and stage (I & II vs. III) for disease specific (HR = 3.523, 95% CI = 1.375-9.026, p = 0.009) and overall survival (HR = 2.230, 95% CI = 1.167-4.264, p = 0.015). The pre-treatment, mean on-treatment and end-of-treatment Hb concentration > 120 g/L carried better prognosis for patients for with squamous cell carcinoma of the anal canal treated with radiochemotherapy. The pre-treatment Hb > 120 g/L was an independent prognostic factor for overall survival of patients with anal canal cancer.

    Papillary renal-cell carcinoma, which accounts for 15 to 20% of renal-cell carcinomas, is a heterogeneous disease that consists of various types of renal cancer, including tumors with indolent, multifocal presentation and solitary tumors with an aggressive, highly lethal phenotype. Little is known about the genetic basis of sporadic papillary renal-cell carcinoma, and no effective forms of therapy for advanced disease exist. We performed comprehensive molecular characterization of 161 primary papillary renal-cell carcinomas, using whole-exome sequencing, copy-number analysis, messenger RNA and microRNA sequencing, DNA-methylation analysis, and proteomic analysis. Type 1 and type 2 papillary renal-cell carcinomas were shown to be different types of renal cancer characterized by specific genetic alterations, with type 2 further classified into three individual subgroups on the basis of molecular differences associated with patient survival. Type 1 tumors were associated with MET alterations, whereas type 2 tumors were characterized by CDKN2A silencing, SETD2 mutations, TFE3 fusions, and increased expression of the NRF2-antioxidant response element (ARE) pathway. A CpG island methylator phenotype (CIMP) was observed in a distinct subgroup of type 2 papillary renal-cell carcinomas that was characterized by poor survival and mutation of the gene encoding fumarate hydratase (FH). Type 1 and type 2 papillary renal-cell carcinomas were shown to be clinically and biologically distinct. Alterations in the MET pathway were associated with type 1, and activation of the NRF2-ARE pathway was associated with type 2; CDKN2A loss and CIMP in type 2 conveyed a poor prognosis. Furthermore, type 2 papillary renal-cell carcinoma consisted of at least three subtypes based on molecular and phenotypic features. (Funded by the National Institutes of Health.).

    The red cell distribution width (RDW) has also been reported to reliably reflect the inflammation and nutrition status and predict the prognosis across several types of cancer, however, the prognostic value of RDW in esophageal carcinoma has seldom been studied. A retrospective study was performed to assess the prognostic value of RDW in patients with esophageal carcinoma by the Kaplan-Meier analysis and multivariate Cox regression proportional hazard model. All enrolled patients were divided into high RDW group (≧15%) and low RDW group (<15%) according to the detected RDW values. Clinical and laboratory data from a total of 179 patients with esophageal carcinoma were retrieved. With a median follow-up of 21months, the high RDW group exhibited a shorter disease-free survival (DFS) (p<0.001) and an unfavorable overall survival (OS) (p<0.001) in the univariate analysis. The multivariate analysis revealed that elevated RDW at diagnosis was an independent prognostic factor for shorter PFS (p=0.043, HR=1.907, 95% CI=1.020-3.565) and poor OS (p=0.042, HR=1.895, 95% CI=1.023-3.508) after adjustment with other cancer-related prognostic factors. The present study suggests that elevated preoperative RDW(≧15%) at the diagnosis may independently predict poorer disease-free and overall survival among patients with esophageal carcinoma.

    Merkel cell carcinoma (MCC), being a small cell carcinoma, would be expected to be sensitive to radiation. Clinical analysis of patients at our center, especially those with macroscopic disease, would suggest the response is quite variable. We have recently established a number of MCC cell lines from patients prior to radiotherapy, and for the first time are in a position to determine their sensitivity under controlled conditions. Some of the MCC lines grew as suspension cultures and could not be single cell cloned; therefore, it was not possible to use clonogenic survival for all cell lines. A tetrazolium based (MTT) assay was used for these lines, to estimate cell growth after {gamma} irradiation. Control experiments were conducted on lymphoblastoid cell lines (LCL) and the adherent MCC line, MCC13, to demonstrate that the two assays were comparable under the conditions used. We have examined cell lines from MCC, small cell lung cancer (SCLC), malignant melanomas, Epstein Barr virus (EBV) transformed lymphocytes (LCL), and skin fibroblasts for their sensitivity to {gamma} irradiation using both clonogenic cell survival and MTT assays. The results show that the tumor cell lines have a range of sensitivities, with melanoma being more resistant (surviving fraction at 2 Gy (SF2) 0.57 and 0.56) than the small cell carcinoma lines, MCC (SF2 range 0.21-0.45, mean SF2 0.30, n = 8) and SCLC (SF2 0.31). Fibroblasts were the most sensitive (SF2 0.13-0.20, mean 0.16, n = 5). The MTT assay, when compared to clonogenic assay for the MCC13 adherent line and the LCL, gave comparable results under the conditions used. Both assays gave a range of SF2 values for the MCC cell lines, suggesting that these cancers would give a heterogeneous response in vivo. The results with the two derivative clones of MCC14 (SF2 for MCC14/1 0.38, MCC14/2 0.45) would further suggest that some of them may develop resistance during clonogenic evolution. 25 refs., 3 figs., 1 tab.

    Oral squamous cell carcinoma is the sixth most common malignancy worldwide. In Bangladesh, it comprises 20% of the whole body malignancies. Several studies found that 15% to 25% of oropharyngeal cancer cases are associated with human papilloma virus (HPV). This study is done to find the association of human papilloma virus subtypes, particularly HPV type 16 and HPV type 18, with the oral squamous cell carcinoma in Bangladeshi patients. In total, 34 diagnosed patients of oral squamous cell carcinoma were included in the study. Extracted DNA from the cancerous tissues was checked for PCR reaction to detect the subtypes of human papilloma virus. Data of the present study suggest that oral squamous cell carcinoma are almost absent in Bangladeshi patients with human papilloma virus, particularly HPV 16 and 18.

    To investigate the clinical usefulness of a follow-up examination using serum squamous cell carcinoma antigen (SCC) for the early detection of recurrence in patients treated for cervical squamous cell carcinoma. 20 patients who were treated for recurrent cervical squamous cell carcinoma between 1997 and 1998, who had experienced a complete remission after radiotherapy and who underwent an SCC test around the time when recurrence was detected, were included in this study. The levels of SCC were measured from the serum of the patients by immunoassay and values less than 2 ng/mL were regarded as normal. The sensitivity of the SCC test for use in the detection of recurrence, the association between the SCC values and the recurrence patterns and the tumor size and stage, and the temporal relation between the SCC increment and recurrence detection were evaluated. The SCC values were above normal in 17 out of 20 patients, so the sensitivity of the SCC test for the detection of recurrence was 85%, and the mean and median of the SCC values were 15.2 and 9.5 ng/mL, respectively. No differences were observed in the SCC values according to the recurrence sites. For 11 patients, the SCC values were measured over a pero id of 6 months before recurrence was detected, and the mean and median values were 13.6 and 3.6 ng/mL, respectively. The SCC values of 7 patients were higher than the normal range, and the SCC values of the other 4 patients were normal but 3 among them were above 1.5 ng/mL. At the time of diagnosis, the SCC valuess were measured for 16 of the 20 recurrent patients, and the SCC values of the patients with a bulky tumor (≥ 4 cm) or who were in stage IIb or III were higher than those of the patients with a non-bulky tumor or who were in stage Ib or IIa. The SCC test is thought to be useful for the early detection of recurrence during the follow up period in patients treated for cervical squamous cell carcinoma.

    Full Text Available ABSTRACT INTRODUCTION: It is well established that cervical lymph node metastasis is the most important prognostic factor in patients with oral squamous cell carcinoma of the upper aerodigestive tract. The definition of parameters and classifications that could separate patients in groups of low, intermediate and high-risk is being attempted for several years. OBJECTIVE: The objective of this study was to determine possible predictive factors related to the occurrence of occult cervical lymph node metastasis through the analysis of histopathological reports of surgical specimens obtained after oral squamous cell carcinoma resection and selective neck dissections of patients initially classified as N0. METHODS: This was a primary, retrospective, observational, case-control study. Histopathological reports were reviewed to determine if some findings were related to the occurrence of occult lymph node metastasis. The events analyzed were oral cavity subsites, pT-stage, muscular infiltration, desmoplasia, vascular emboli, perineural infiltration, tumor thickness and compromised margins. RESULTS: Occult cervical metastasis accounted for 19.10 percent of the cases. Desmoplasia, perineural infiltration, tumor thickness and pT4a stage are predictive factors of occult neck metastasis (p-value = 0.0488, 0.0326, 0.0395, 0.0488, respectively. CONCLUSION: The accurate definition of predictive factors of occult cervical metastasis may guide the selection of patients that should be referred to radiotherapy, avoiding the unnecessary exposure of low-risk patients to radiation and allowing a better regional control of the disease in those of moderate or high risk.

    Full Text Available Merkel cell carcinoma (MCC is a rare aggressive neuroendocrine carcinoma of the skin that shows locoregional or distant metastasis. Metastasis of MCC to body cavity effusion is extremely rare; only three cases have been reported so far. Metastatic MCC in effusion cytology shows small blue round cells with fine stippled chromatin like other small blue round cell tumors such as small cell lung carcinoma or lymphoma. The diagnosis of metastatic MCC can grant patients good chances at recently advanced therapeutic options. Here, we present a case of metastatic MCC to pleural effusion with characteristic single file-like pattern.

    Full Text Available Pulmonary squamous cell carcinoma is the second most common non–small cell malignancy of the lung. It commonly metastasizes to the adrenal glands, bone, liver, brain, and kidneys. Most occurrences of metastatic squamous cell carcinoma involving the gastrointestinal tract originate from primary lung tumors. Metastasis to the duodenum, however, is exceedingly rare, with very few cases of stomach or duodenal involvement described in the literature. We report the case of a patient with stage IV pulmonary squamous cell carcinoma metastasizing to the duodenum with an uncommon presentation to add to the paucity of literature available regarding this rare finding.

    Objective: To provide a reference for determination of the postoperative radiotherapy target volume for thoracic esophageal squamous cell carcinoma. Background data: The irradiation target volume is important for effective postoperative treatment of thoracic esophageal squamous cell carcinoma. Methods: One hundred forty patients with recurrent or metastatic thoracic esophageal squamous cell carcinoma who had been treated with radical surgery but not with postoperative radiotherapy were enrolled in this study. The information of locoregional recurrence and distant metastasis for these patients was analyzed. Results: The median time to progression in the 140 patients with recurrence or metastasis was 18.3 months (range 15.4-21.1 months). Anastomotic recurrence accounted for 13.6% of treatment failures. The supraclavicular and station 1-5 and 7 lymph nodes had high metastasis rates for esophageal squamous cell carcinomas in all locations. The order from highest to lowest metastasis rate for the station 3 and 4 lymph nodes was middle, upper and lower thoracic esophageal regions and the order for upper abdominal lymph nodes was lower, middle, and upper thoracic esophageal regions. Locoregional recurrence was the most common type of recurrence. Conclusions: For upper and middle thoracic esophageal squamous cell carcinomas, the anastomosis, supraclavicular, and station 1-5 and 7 lymph nodes should be delineated as the postoperative prophylactic irradiation target volume with upper abdominal lymph nodes excluded; for lower thoracic esophageal squamous cell carcinomas, anastomosis, supraclavicular, station 1-5 and 7 lymph nodes and upper abdominal lymph nodes should be delineated as the postoperative prophylactic irradiation target volume.

    Full Text Available Spindle cell carcinoma of hpopharynx is a rare pathology. It is a poorly differentiated variant of squamous cell carcinoma and morphologically resembles sarcoma. This is a disease of old age. It is usually associated with smoking and alcohol abuse. When it is associated with radiation exposure history it behaves more aggressively. Surgery is considered as the main modality of treatment and adjuvant radiotherapy if necessary. Here we present a case of 79 year old male with spindle cell carcinomaof right piriform fossa with 2-month history of progressive dysphasia and hoarseness that has been affecting his ability to speak and swallow with history of weight loss and past history of radiotherapy. So possibility of spindle cell carcinoma of the hypopharynx should beconsidered in an old patient with rapidly developing swelling of the hypopharynx with past history of radiation exposure. As it is a highly aggressive disease it should be treated timely and more aggressively to prolong the survival of the patient.

    1997-01-01

    Purpose: To determine the proportion of patients with squamous cell carcinoma of the maxillary sinus who will fail in regional nodes without elective neck treatment and to identify any prognostic factors that may influence neck control. Methods and Materials: From 1971-1995, 42 consecutive patients with squamous cell carcinoma of the maxillary sinus were seen at our department for curative treatment. There were 35 males and 7 females, with a median age at diagnosis of 63.5 years (range, 42-77 years). One tumor was classified as T1, 5 had T2, 15 had T3, and 21 had T4 disease. Four of 42 patients (9.5%) had cervical lymphadenopathy at initial presentation. Thirty-three patients had surgical resection and radiotherapy and nine had radiotherapy alone. None of the 38 patients with clinical NO necks received elective treatment to the cervical nodes. Results: Median overall survival was 30 months for all patients. Of the 38 patients with NO disease, 11 (28.9%) had neck recurrence. Of the 11 neck failures, 9 were ipsilateral only, 1 was contralateral, and 1 had bilateral neck recurrence. The most common site of neck failure was in the upper neck (submandibular and jugulodigastric lymph nodes). Four of the 38 patients (10.5%) had isolated neck failure. Only tumor stage was found to be significant for neck relapse, with T1 and T2 doing worse compared to T3 and T4 tumors. Location of tumor (infrastructure vs. suprastructure), involvement of the oral cavity/oropharynx, nasal cavity, nasopharynx or orbit did not predict for cervical node relapse. Local control at the primary site was likewise not prognostic. The median overall survival for patients who remained NO was 80 months and for those with initial cervical involvement or recurred in the neck without elective neck irradiation was 25 months (p = 0.05). Conclusion: Based on the 28.9% rate of neck recurrence and the poor median survival of patients who recur in the neck, we recommend prophylactic ipsilateral neck irradiation

    The Purpose of this study was to evaluate retrospectively the management and prognosis of Merkel cell carcinoma of the eyelid in Japanese patients. Cases diagnosed as Merkel cell carcinoma of the eyelid from January 1993 to February 2005 in 111 institutions in Japan were included in this retrospective study. Management and prognosis were evaluated. The total number of cases enrolled was 21 (5 male and 16 female patients). Excision of the tumor was carried out in 18 cases. Two cases were treated with either irradiation or local injection of interferon after biopsy of the tumor. After initial treatment, there were recurrences in 3 cases; local recurrence in one case and nodal metastasis in two cases. No patient died because of Merkel cell carcinoma of the eyelid. Excision with wide surgical margins with irradiation is recommended as the first choice of treatment for Merkel cell carcinoma of the eyelid. Because the number of patients was only 21 and the duration of observation was short, further investigation is necessary to determine the optimal management and more accurate prognosis for Merkel cell carcinoma.

    Full Text Available Abstract Background The incidence of multiple primary malignant neoplasms increases with age and they are encountered more frequently nowadays than before, the phenomenon is still considered to be rare. Case presentation We report a case of a man in whom urinary bladder transitional cell carcinoma, metachronous prostate adenocarcinoma and small cell lung carcinoma were diagnosed within an eighteen-month period. The only known predisposing factor was that he was heavy smoker (90–100 packets per year. The literature on the phenomenon of multiple primary malignancies in a single patient is reviewed and the data is summarized. Conclusion It is important for the clinicians to keep in mind the possibility of a metachronous (successive or a synchronous (simultaneous malignancy in a cancer patient. It is worthy mentioning this case because clustering of three primary malignancies (synchronous and metachronous is of rare occurrence in a single patient, and, to our knowledge, this is the first report this combination of three carcinomas appearing in the same patient.

    A bibliographic review was conduced on the use of 5-methyl aminolevulinate in dermatology, specifically in the treatment of actinic keratosis, epidermoid carcinoma and basal cell carcinoma. The basic fundamentals of photodynamic therapy are described. The preparation and method of use of photodynamic therapy with 5-methyl aminolevulinate (MAL-PDT) are detailed. The clinical studies that were realized with photodynamic therapy for the treatment of actinic keratosis, epidermoid carcinoma and basal cell carcinoma are mentioned. Different photo-inducible agents and other current therapeutic options of first-line are compared. The MAL-PDT has have the advantage of to present less side effects and the same have been more tolerable than liquid nitrogen and 5 fluorouracil. The MAL-PDT has been considered as an effective option for the treatment of Bowen's disease. Invasive epidermoid carcinoma has existed without evidence to support the routine use of this therapeutic. For superficial basal cell carcinoma, the MAL-PDT has presented a high cure rate and transient and manageable side effects in extensive and multiple lesions. The MAL-PDT has been an effective and safe treatment in patients with basal cell carcinoma, for those with less depth of 2mm. The MAL-PDT could play an important role in the field of prevention with immunosuppressed patients, particularly, those that have required transplant and its immunosuppression has been pharmacological. The use or not of the MAL-PDT, should be evaluated individually for each patient and to have suitable characteristics for each disease that was cited in this review. The photodynamic therapy with 5-methyl aminolevulinate has been a therapeutic modality of considerable economy, however, it should be evaluated in the context of number of inquiries and side effects that have offered other therapeutic modalities [es

    Recurrent oropharyngeal squamous cell carcinoma causes great morbidity and mortality. This systematic review analyses survival outcomes following salvage surgery for recurrent oropharyngeal squamous cell carcinoma. A comprehensive search of various electronic databases was conducted. Studies included patients with recurrent or residual oropharyngeal squamous cell carcinoma treated with salvage surgery. Primary outcomes were survival rates following salvage surgery. Secondary outcomes included time to recurrence, staging at time of recurrence, post-operative complications, and factors associated with mortality and recurrence. Methodological appraisal and data extraction were conducted as per Joanna Briggs Institute methodology. Eighteen articles were included. The two- and five-year survival rates of the patients were 52 per cent and 30 per cent respectively. Improvements in treatment modalities for recurrent oropharyngeal squamous cell carcinoma were associated with improvements in two-year overall survival rates, with minimal change to five-year overall survival rates. Various factors were identified as being associated with long-term overall survival, thus assisting clinicians in patient counselling and selection for salvage surgery.

    Full Text Available Abstract Background The goal of this study was to evaluate the somatic and psychological effects by means of QUALITY OF LIFE (QOL of surgical treatment of patients with oral squamous cell carcinoma. The factors gender, age, nicotine consumption, and tumour stage were taken into consideration. Methods 54 patients after surgical resection of oral squamous cell carcinomas (OSCC were analysed from 01.09.2005 to 31.05.2008. Inclusion criteria for the study were: age at least 18 years, no indication or treatment of synchronous and metachronous tumours. German translations of the EORTC H&N-35 and EORTC QLQ-C-30 questionnaires, as well as a general socioeconomic patient history were used as measuring instruments. The questionnaires were completed independently by the patients. The answers were translated into scale values for statistical evaluation using appropriate algorithms. Results Analysis of the EORTC-QLQ-C-30 questionnaires demonstrated a tendency of more negative assessment of emotional function among the female participants, and a more negative evaluation of social function among the male participants. Greater tumour sizes showed significantly lower bodily function (p = 0.018. While a smaller tumour size was significantly associated with lower cognitive functioning (p = 0.031. Other cofactors such as age, nicotine consumption, and tumour stage only showed a tendency to influence the quality of sleep and daily life. Conclusions The data obtained within this investigation demonstrated that gender had the most significant power on the subjectively perceived postoperative quality of life. This factor is important e.g. in preoperative decision making regarding immediate microvascular reconstruction after e.g. mandibular resection and therefore QOL assessment should become integral component of the care of patients with OSCC.

    1997-01-01

    Purpose/Objective: Merkel cell carcinoma is a rare, aggressive neuroendocrine tumor of the skin with a predisposition for local-regional and distant spread. The addition of radiotherapy after wide local excision has improved local control, but distant spread continues to be a significant problem. This is an update of our experience in the treatment of Merkel cell carcinoma at the University of Florida. Materials and Methods: Of 25 patients treated for Merkel cell carcinoma at the University of Florida between 1984 and 1996, minimum follow-up was 1 year; no patient was lost to follow-up. Nineteen patients were treated at the time of the initial diagnosis, and six were treated after local-regional recurrence. Of the 19 previously untreated patients, 14 had primary sites in the head and neck region, and five had primary sites elsewhere. Results: The 5-year absolute survival, cause-specific survival, and local-regional control rates for the entire group were 26%, 30%, and 79%, respectively. Patients treated with radiotherapy at the time of initial presentation had 5-year absolute survival, cause-specific survival, and local-regional control rates of 36%, 42%, and 74%, respectively. Most deaths were due to distant metastasis. Site of the primary tumor (in or out of the head and neck region) was not associated with any difference in the outcome. Of six patients treated at the time of local-regional recurrence, five died of distant metastasis at 8, 16, 27, 37, and 38 months from the time of treatment. One patient was alive and without evidence of disease 24 months after treatment. All patients treated at the time of local-regional recurrence had local-regional control after radiotherapy. Conclusion: This update confirms that radiotherapy and wide local excision is effective local-regional treatment for Merkel cell carcinoma of the skin, but distant metastasis remains a significant problem in this disease. The role and effectiveness of chemotherapy as part of the initial

    The prognoses of submucosal esophageal squamous cell carcinoma patients vary. Patients with favorable prognoses may receive less invasive or nonsurgical interventions, whereas patients with poor prognoses or advanced esophageal cancer may require aggressive treatments. We sought to identify prognostic factors for patients with submucosal esophageal squamous cell carcinoma, focusing on lymph node metastasis and recurrence. We included 137 submucosal esophageal squamous cell carcinoma patients who had undergone transthoracic esophagectomy with systematic extended lymph node dissection. Submucosal tumors were classified as SM1, SM2, and SM3 according to the depth of invasion. Prognostic factors were determined by univariable and multivariable analyses. Lymph node metastasis was observed in 18.8%, 30.5%, and 50.0% of SM1, SM2, and SM3 cases, respectively. The overall 5-year recurrence rate was 21.9%; the rates for SM1, SM2, and SM3 tumors were 9.4%, 18.6%, and 34.8%, respectively. The SM1 tumors all recurred locoregionally; distant metastasis occurred in SM2 and SM3 cases. The 5-year overall survival rates were 83%, 77%, and 59% for SM1, SM2, and SM3 cases, respectively. On univariable analysis, lymph node metastasis, depth of submucosal invasion (SM3 versus SM1/2), and tumor location (upper thoracic versus mid/lower thoracic) were poor prognostic factors for overall survival. Multivariable Cox regression analyses identified depth of submucosal invasion (hazard ratio 2.51, 95% confidence interval: 1.37 to 4.61) and tumor location (hazard ratio 2.43, 95% confidence interval: 1.18 to 4.63) as preoperative prognostic factors. Tumor location (upper thoracic) and infiltration (SM3) are the worse prognostic factors of submucosal esophageal squamous cell carcinoma, but lymph node metastasis is not a predictor of poorer prognosis.

    Full Text Available Nevoid basal cell carcinoma syndrome (also named Gorlin-Goltz syndrome is a rare disease. Commonly seen features include multiple odontogenic keratocysts (OKCs, nevus-like basal cell carcinoma, and bifid ribs. Genetic alterations of the PTCH1 gene are associated with the disease. Herein, we report the case of a 15-year-old girl who presented with multiple OKCs, a bifid rib, ectopic calcification of the falx cer-ebri, and an arachnoid cyst of the cerebrum. No basal cell carcinoma was identified. In addition, a search for genetic alterations was performed on the patient. We identified a genetic mutation of C→T in exon 12 (c.1686 bp and a G→C mutation in intron 13 (g.91665 bp of the PTCH1 gene. Although a similar mutation in exon 12 was reported in a literature search, the mutation in intron 13 has not previously been reported. The patient has continued to be followed-up almost 3 years after the surgery with no recurrence of the OKCs or development of basal cell carcinoma.

    This paper reports the results of a study of risk factors for recurrence in non-irradiated sites in patients with squamous cell carcinoma of the uterine cervix who received postoperative irradiation. It also discusses clinical experience with such patients, particularly those with a poor prognosis, based on a review of the literature. The study was conducted at the National Shikoku Cancer Center in 62 patients with squamous cell carcinoma of the uterine cervix (mean age=50.5, range=30-66) who received 10 MeV postoperative irradiation with a Linac between 1981 and 1990. An analysis was performed in terms of sites and times of recurrence, risk factors for distant metastasis, and groups at high risk for distant metastasis. Based on the results of the study as well as the review of the literature, it was concluded that squamous cell carcinoma of the uterine cervix is sensitive to radiation therapy and that the clinical outcome of local treatment is satisfactory. However, systemic chemotherapy should be considered for patients who are suspected of having minute distant metastasis at the time of surgical operation, i.e., those with moderate to severe vascular space invasion, multiple lymph node metastasis, parametrium infiltration, and/or endometrial infiltration.

    Objective: Small cell carcinoma of the uterine cervix is a rare and aggressive tumor. This tumor is similar to small cell carcinoma of the lung with a tendency to metastasize early. While there has been an increasing interest in the use of chemotherapy regimens similar to those used for small cell carcinoma of the lung, the optimum local therapy for small cell carcinoma of the cervix remains unknown. We reviewed the treatment outcome of patients with small cell carcinoma of the cervix diagnosed in our cancer center with an emphasis on the local/regional disease control. Material and Methods: Between 1983 and 1993, medical records of patients diagnosed with carcinoma of the uterine cervix were reviewed. There were 281 patients with carcinoma of the uterine cervix referred to our department for radiation treatment. Seven patients had pathologic diagnosis of either small cell or neuroendocrine histology. Details of the treatments and follow-up information of these patients were reviewed with a medium follow-up period of three years (range - 1 to 4 years). Results: Five patients had pure small cell histology. Two patients had mixed histology: one with mixed small cell anaplastic neuroendocrine cells and a small foci of adenocarcinoma, the other had mixed small cell and squamous cell histology. Four patients had clinical stage IB disease. The others had IIA, IIB, and IIIB disease, respectively. All patients received either irradiation (XRT) alone or as part of the local therapy. Three patients received XRT alone, one received surgery followed by XRT, one received XRT followed by surgery, and the remaining two had triple modality treatment (chemotherapy, surgery, and XRT). Three patients were alive without evidence of disease recurrence at the last follow-up. Two of these received adjuvant chemotherapy in addition to local therapy. The third patient, whose tumor was smaller than one cm at the time of diagnosis, received XRT alone. Four patients died with disease

    Basaloid squamous cell carcinoma (BSCC) of the esophagus is a rare carcinoma with distinct characteristics. No standard treatment has been established. This retrospective study was designed to investigate the clinical and pathological characteristics, diagnosis, treatment, and prognosis of esophageal BSCC. Clinical data were retrospectively analyzed from 26 patients with pathologically confirmed esophageal BSCC who underwent transthoracic esophagectomy with lymphadenectomy between January 1995 and June 2010 at the Cancer Hospital of Shantou University Medical College. Clinicopathologic data between BSCC patients and different histologic grades of esophageal squamous cell carcinoma (ESCC) patients were statistically compared by means of the χ(2) test or Fisher's exact test. The Kaplan-Meier and log-rank methods were used to estimate and compare survival rates. Microscopically, BSCC was characterized by a nesting, lobular, or trabecular arrangement of small crowded cells with scant cytoplasm. None of the histologic specimens taken at preoperative esophagoscopy were diagnosed as BSCC. The median survival time (MST) of the 26 patients was 29.0 months (95% confidence interval, 9.0-49.0), and the 1-, 3-, and 5-year overall survival rates were 73.1, 42.7, and 36.6%, respectively. The MST for BSCC patients was significantly lower than that of well-differentiated SCC patients (P = 0.024), but there were no significant differences between the MST for BSCC patients and that of moderately or poorly differentiated SCC patients (P > 0.05). BSCC of the esophagus is a rare but distinctive disease and is prone to be misdiagnosed by endoscopic biopsy. The prognosis is poorer than well-differentiated SCC, but similar to moderately or poorly differentiated SCC.

    Nevoid basal cell carcinomas (NBCCs) are a prototype of a genetic form of basal cell carcinoma. These basal cell cancers, rather than being caused by genetic factors alone, are most likely the product of genetic and environmental factors. The NBCC syndrome provides a model for studying tumors induced by ionizing radiation and for viewing carcinogenesis as a multistage process explainable by a minimum of two steps. The interaction of genetic and environmental factors in producing tumors to which an individual is predisposed can be studied in patients with the NBCC syndrome and childhood medulloblastoma that was treated by radiation therapy. Individuals with the NBCC syndrome represent a special subgroup with a hereditary predisposition to basal cell carcinoma in whom ionizing radiation may supply the subsequent mutation necessary for tumor development. The genetically altered epidermis underlying the palm and sole pits found in patients with the syndrome represents basal cell carcinoma in situ from which basal cell carcinomas develop, albeit infrequently. The restrained biologic behavior of most of these tumors contrasts with the usual destructive behavior of the NBCCs of the head and neck in the same patient

    Background and purpose: several multimodal strategies have been developed to treat patients with squamous cell carcinoma of the oral cavity. The advantages of preoperative radiochemotherapy are downstaging of the primary tumor, an increased resectability rate, and the elimination of micrometastases. After successful phase II trials, the following therapy regimen for resectable advanced oral carcinoma was applied. Patients and methods: 134 patients with resectable squamous cell carcinoma of the oral cavity stage II-IV received neoadjuvant radiochemotherapy consisting of 39.6 Gy in daily fractions of 1.8 Gy and concomitant carboplatin (70 mg/m 2 days 1-5). Radical resection and neck dissection were carried out afterwards. Results: after a median follow-up of 73 months, 82 patients (61%) had died. 54 patients (40%) experienced locoregional relapses or distant metastases. The overall survival was 65% ± 4% after 2 years and 45% ± 4% after 5 years. Cox regression survival analysis identified tumor regression, extracapsular lymph node spread and resection state as prognostic factors. Side effects of grade 3-4 were rare. Conclusion: neoadjuvant radiochemotherapy with subsequent radical surgery can be recommended as an effective and safe treatment for primary resectable advanced tumors of the oral cavity. Acute and long-term toxicities appear to be moderate. (orig.)

    Testicular germ cell tumours (TGCT), including seminomas, embryonal carcinomas, teratomas and yolk sac tumours, have a common precursor, the carcinoma in situ (CIS) cell. Recent gene expression studies displaying close similarity of CIS cells to embryonic stem cells support the longstanding theory...... should be made to obtain diagnosis at the CIS stage, as intervention is possible before an invasive tumour develops, thus reducing the necessity for intensive therapy. CIS may be suspected in patients with an assumed extragonadal GCT or cryptorchidism, and in intersex patients and selected cases...

    Nasopharyngeal carcinoma (NPC) is one of head and neck cancer with a poor prognosis because of the position of the tumor adjacent to the skull base and vital structures. Degradation of extracellular matrix that will cause tumor cells to invade surrounding tissues, vascular or lymphatic vessels. One that plays a role in the extracellular matrix degradation process is matrix metalloproteinase-9 (MMP-9). MMP-9 plays a role in tumor invasion process, metastasis and induction of tumor tissue vascularization. To determine the expression of MMP-9 in patients with nasopharyngeal carcinoma, a descriptive study was conducted by examining immunohistochemistry MMP-9 in 30 NPC tissues that had never received radiotherapy, chemotherapy or combination. Frequency distribution of NPC patient mostly in the age group 41-50 years old and 51-60 years were nine people (30.0%); men (73.3%) and non-keratinizing squamous cell carcinoma (53.3%) histopathology type. The overexpression of MMP-9 in patients with nasopharyngeal carcinoma were mostly found in advance stage.

    To explore the role of Major Vault Protein (MVP) in oral cavity squamous cell carcinoma patients. 131 consecutive patients suffering from oral cavity squamous cell carcinoma were included in the study. In the whole series, the mean follow-up for survivors was 123.11 ± 40.36 months. Patients in tumour stages I and II were referred to surgery; patients in stage III-IV to postoperative radiotherapy (mean dose = 62.13 ± 7.74 Gy in 1.8-2 Gy/fraction). MVP expression was studied by immunohistochemistry in paraffin-embedded tumour tissue. MVP expression was positive in 112 patients (85.5%) and no relation was found with clinic pathological variables. MVP overexpression (those tumours with moderate or strong expression of the protein) was related to insulin-like growth factor receptor-1 (IGF-1R) expression (P = 0.014). Tumour stage of the disease was the most important prognostic factor related to survival. Tumours overexpressing MVP and IGF-1R were strongly related to poor disease-free survival (P = 0.008, Exp(B) = 2.730, CI95% (1.302-5.724)) and cause-specific survival (P = 0.014, Exp(B) = 2.570, CI95% (1.215-5.437)) in patients achieving tumour stages III-IV, in multivariate analysis. MVP and IGF-1R expression were related in oral squamous cell carcinoma and conferred reduced long-term survival in patients suffering from advanced stages of the disease.

    2009-01-01

    Serum Squamous Cell Carcinoma Antigen (SCC-Ag) by ELISA technique and Alpha-fetoprotein (AFP) by IRMA technique were measured in 65 patients with hepatic focal lesion. 49 patients suffered from proved hepatocellular carcinoma and 16 patients were having cirrhosis and 20 normal controls. Median levels of serum AFP and SCC-Ag in HCC patients was significantly higher when compared with both cirrhotic patients and controls. On using receiver operator characteristic curve to improve sensitivity and specificity of AFP and SCC-Ag for detection of HCC, the best chosen cut-off values were 40 IU/mL for AFP and 2.55 ng/L for SCC-Ag, these yielded a sensitivity of 67.2% and 61.2% respectively and specificity 100%. The diagnostic sensitivity of them increased to 87.7% when they was combiendly calculated. It was found that the combined use of AFP and SCC-Ag is useful in screening patients with hepatic focal lesion to increase the chance of early diagnosis of HCC patients.

  10. SQUAMOUS CELL CARCINOMA OF THE HEAD AND NECK: NEW AVENUES OF TREATMENT?

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Squamous cell carcinoma of the head and neck counts for 3 % of all cancers in men and half of this number less in women with a 5-year survival of 61 %. While the number of laryngeal carcinoma is decreasing, carcinoma of the oral cavity related to an infection by the human papilloma virus (HPV, high-risk subtypes is increasing, especially in younger patients. HPV related squamous cell carcinomas show better survival data, especially in regard to recurrence free rates or secondary carcinoma of adjacent locations. Squamous cell carcinomas related to the presence of HPV DNA material is almost exclusively found in carcinoma of the oral cavity and oropharyngeal mucosa. Much less frequently HPV is present in hypopharyngeal carcinomas and even less number of cases of squamous cell carcinoma with proof for HPV in the nasopharynx and larynx. In case of evidence for HPV DNA; most cases are positively tested for subtype 16, followed by subtype 18. As a surrogate immunhistochemical marker, p16 INK4A is stained positive, cytoplasmic and nuclear. In a small study by ourselves, we found a positive correlation in 100 % of p16 INK4A positivity and positive HPV testing. Oral squamous cell carcinoma is more frequently related to HPV in patients below 50 years of age with a prevalence of ca. 20 %. Whilst HPV high-risk positive carcinomas show very few mutations in single signalling molecules of the downstream receptor tyrosin kinase pathways, HPV negative carcinomas show in many cases a chaotic DNA mutation type with typical mutations in tumor suppressor genes, as p53 and CDKN2A. This pattern is often seen in carcinoma types develop from a summation of accidental mutations often caused by toxins (e.g. inhaled cigarette smoke. However, it is discussed and under investigation whether a subset of head and neck squamous cell carcinomasdevelop from so called driver mutations, as are called mutations in critical members of signalling pathways and receptor tyrosin kinases

Retrospective chart review of 6 consecutive patients with biopsy-proven orbital basal cell carcinoma and 2 additional patients with extensive periocular basal cell carcinoma who were treated with oral vismodegib (150 mg/day) was performed. Basal cell carcinoma extended in the orbit in 6 of 8 patients (involving orbital bones in 1 patient), and 2 of 8 patients had extensive periocular involvement (1 with basal cell nevus syndrome). Vismodegib therapy was the only treatment in 6 patients, off-label neoadjuvant in 1 patient, and adjuvant treatment in 1 patient. Orbital tumors in all 4 patients who received vismodegib as sole treatment showed partial response with a mean 83% shrinkage in tumor size after a median of 7 months of therapy. In the 2 patients receiving vismodegib as neoadjuvant or adjuvant therapies, there was complete response after a median of 7 months of therapy and no evidence of clinical recurrence after discontinuing therapy for a median of 15 months. The 2 patients with extensive periocular involvement experienced complete clinical response after a median 14 months of treatment. During treatment, the most common side effects were muscle spasm (75%) followed by alopecia (50%), dysgeusia (25%), dysosmia, and episodes of diarrhea and constipation (13%). Basal cell carcinoma with orbital extension and extensive periocular involvement responds to vismodegib therapy. The long-term prognosis remains unknown, and additional prospective studies are indicated.

    We studied overall survival and prognostic factors in patients with sarcomatoid renal cell carcinoma treated with nephrectomy and systemic therapy in the cytokine and targeted therapy eras. This is a retrospective study of patients with sarcomatoid renal cell carcinoma who underwent nephrectomy and received systemic therapy at our center in the cytokine era (1987 to 2005) or the targeted therapy era (2006 to 2015). Multivariate regression models were used to determine the association of covariables with survival. Of the 199 patients with sarcomatoid renal cell carcinoma 167 (83.9%) died (median overall survival 16.5 months, 95% CI 15.2-20.9). Survival of patients with clear cell histology was significantly longer vs those with nonclear cell histology (p = 0.034). Patients with synchronous metastatic disease had significantly shorter survival than patients with metachronous metastatic disease (median 12.1 vs 23.3 months, p = 0.0064). Biopsy of the primary tumor or a metastatic site could detect the presence of sarcomatoid features in only 7.5% of cases. Although a significant improvement in survival rate was observed in the first year in patients treated in the targeted therapy era (p = 0.011), this effect was attenuated at year 2, disappeared at years 3 to 5 after diagnosis and was not evident in patients with poor risk features. Patients with sarcomatoid renal cell carcinoma still have poor prognosis with no clear long-term benefit of targeted therapy. This underscores the need to develop more effective systemic therapies for these patients. Copyright © 2017 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

    Barilla, R.; Sycova-Mila, Z.

    2009-01-01

    Renal Cell Carcinoma (RCC) accounts for approximately 4 % of all malignancies. Much is known about the pathogenesis of RCC because of studies examining its close relationship with dysfunction of the Von Hippel-Lindau gene (VHL) and hypoxia inducible factor (HIF). Mammalian target of rapamycin (mTOR) regulates nutritional needs, cell growth, and angiogenesisi in cells by down regulating or up regulating a variety of proteins including HIF. Until 2005, only a single agent high dose interleukin 2 was approved by Food and Drug Administration (FDA) for treatment of advanced renal cell carcinoma. More recently thanks to better knowledge in the field of molecular biology new treatment options appeared. Sunitinib and bevacizumab are currently considered to be treatment of first choice for patients in good and intermediate prognostic group and sorafenib is preferred second line treatment in the same patient population pretreated with cytokines after disease progression. Temsirolimus and everolimus, rapamycin analouges, have recently been tested in III trials in first and second line treatment in patients with advanced metastatic clear cell renal cell carcinoma.

    2008-01-01

    Objective: To present computed tomography findings observed in four patients submitted to radical nephrectomy for renal cell carcinoma who developed pancreatic metastases afterwards. Materials and methods: The four patients underwent radical nephrectomy for stage Tz1 (n=2) and stage T3a (n=2) renal cell carcinoma. The mean interval between nephrectomy and detection of pancreatic metastases was eight years. Two asymptomatic patients presented with solitary pancreatic metastases (confined to the pancreas). Two symptomatic patients presented with single and multiple pancreatic metastases, both with tumor recurrence in the contralateral kidney. Results: Computed tomography studies demonstrated pancreatic metastases as solitary (n=2), single (n=1) or multiple (n=1) hypervascular lesions. Partial pancreatectomy was performed in two patients with solitary pancreatic metastases and both are free of disease at four and two years after surgery. Conclusion: Pancreatic metastases from renal cell carcinoma are rare and can occur many years after the primary tumor presentation. Multiple pancreatic metastases and pancreatic metastases associated with tumor recurrence in the contralateral kidney are uncommon. Usually, on computed tomography images pancreatic metastases are visualized as solitary hypervascular lesions, simulating isletcell tumors. Surgical management should be considered for patients with solitary pancreatic lesions. (author)

    Merkel cell carcinoma is a rare and aggressive neoplasm originating from mechanoreceptor Merkel cells of the stratum basale of the epidermis. Cases affecting the vulva are exceedingly rare, with the currently available literature primarily in case report form. Systematic review of the PubMed database returned 17 cases of Merkel cell carcinoma affecting the vulva. Patients presented at a mean age of 59.6 years with a firm, mobile vulvar mass. Symptoms of pain, erythema, pruritus, edema, and ulceration have been reported. Tumor histology is consistent with that of neuroendocrine tumors and typical Merkel cell carcinomas. Neuroendocrine and cytokeratin immunostains are frequently utilized in histopathological workup. Surgical management was the unanimous first-line therapy with adjuvant radiation in most cases. Recurrence occurred in 70.6% of patients at a mean follow-up of 6.3 months. Mortality was at 47.0% at a mean of 7.8 months after initial operation. Merkel cell carcinoma affecting the vulva is an extremely rare and highly aggressive neoplasm. The present review of published cases serves to comprehensively describe the clinical course and treatment approaches for vulvar Merkel cell carcinoma.

    Full Text Available Due to the rarity of Merkel cell carcinoma (MCC, prospective clinical trials have not been practical. This study aimed to identify biomarkers with prognostic significance. While sixty-two patients were identified who were treated for MCC at our institution, only seventeen patients had adequate formalin-fixed paraffin-embedded archival tissue and followup to be included in the study. Patients were stratified into good, moderate, or poor prognosis. Laser capture microdissection was used to isolate tumor cells for subsequent RNA isolation and gene expression analysis with Affymetrix GeneChip Human Exon 1.0 ST arrays. Among the 191 genes demonstrating significant differential expression between prognostic groups, keratin 20 and neurofilament protein have previously been identified in studies of MCC and were significantly upregulated in tumors from patients with a poor prognosis. Immunohistochemistry further established that keratin 20 was overexpressed in the poor prognosis tumors. In addition, novel genes of interest such as phospholipase A2 group X, kinesin family member 3A, tumor protein D52, mucin 1, and KIT were upregulated in specimens from patients with poor prognosis. Our pilot study identified several gene expression differences which could be used in the future as prognostic biomarkers in MCC patients.

    Agha, F.P.; Keren, D.F.

    1985-01-01

    Spindle-cell squamous carcinoma of the esophagus is a rare malignant tumor. It is characterized by a large bulky mass in the middle third of the esophagus with a lobulated surface and local expansion of the esophagus. This lesion may be pedunculated and cause relatively little obstruction despite its bulk. The current view, based on ultrastructure and immunohistochemical evidence, has confirmed that the sarcomatous component of the squamous cell carcinoma originates from mesenchymal metaplasia of squamous cells. On the basis of this evidence and clinical behavior, it seems appropriate to consider carcinosarcoma and pseudosarcoma as equivalents and as variants of squamous cell carcinoma. Four patients with spindle-cell squamous carcinoma, an unusual subset of squamous carcinoma, are described, and the salient radiographic and pathologic features of this disorder's distinctive biphasic morphology are discussed

    Purpose: To retrospectively evaluate the outcome after radical radiotherapy (RT) and surgical salvage and assess the risk of late toxicity for patients with primary subglottic squamous cell carcinoma treated at our center. Methods and Materials: Between 1971 and 1996, 43 patients with primary squamous cell carcinoma of the subglottis (35 men, 8 women) were treated with radical RT. All received megavoltage irradiation, most commonly to a dose of 50-52 Gy in 20 fractions during 4 weeks (39 patients). The median follow-up was 4.2 years. Results: Local control was achieved with RT alone in 24 (56%) of the 43 patients: 7 of 11 with T1, 8 of 12 with T2, 4 of 8 with T3, and 5 of 12 with T4. The 5-year actuarial local relapse-free rate was 52%. Subsequent local control was achieved in 11 of the 13 patients with failed RT and attempted surgical salvage, for an ultimate local control rate of 81.4% (35 of 43). The 5-year overall and cause-specific actuarial survival rate was 50.3% and 66.9%, respectively. No patients developed Grade 3 or 4 late radiation morbidity. Conclusion: These data support the use of primary RT in the treatment of patients with primary squamous cell carcinoma of the subglottis as an appropriate treatment approach providing an option for laryngeal conservation

    Gingival squamous cell carcinoma have a relatively poor prognosis and large differential diagnosis (periodontitis, osteomyelitis, etc.), therefore, it is usually diagnosed at a late stage. Hematogenous dissemination occurs in only about 10% of cases, including lung (66%), bone (22%), liver (10%), skin, bone marrow and mediastinum. Bone metastases are very rare compared to other malignancies, most commonly affect the axial skeleton (spine, pelvis, ribs and lumbar spine). In our case, we presented a patient with gingival squamous cell carcinoma and bone metastasis in the forearm detected with Whole Body Bone Scintigraphy (WBS), combined with Single Photon Emission Tomography /Computed Tomography (SPECT /CT). The obtained data suggest that the single use of WBS was not informative enough for making the final diagnosis, but the result of combined functional-morphological approach was the most pathognomonic. Thus, with single study can be obtained a complex information, which leads to a fast therapeutic decision. Key words: SPECT/CT. GINGiVAL. SQUAMOUS CELL CARCINOMA

    We investigated the tolerability of cetuximab plus radiotherapy in Japanese patients with untreated locally advanced squamous cell carcinoma of the head and neck. Patients with epidermal growth factor receptor-expressing locally advanced squamous cell carcinoma of the head and neck received cetuximab (400 mg/m 2 initial dose then 250 mg/m 2 weekly) for 7 weeks plus concomitant boost radiotherapy (weeks 2-7: once daily [1.8 Gy] for 3.6 weeks, then twice daily [1.8 Gy morning and 1.5 Gy afternoon] for 2.4 weeks). The primary endpoint was treatment completion rate (the rate of treated patients completing ≥70% of the planned cetuximab dose and the full dose of radiotherapy within 2 weeks over the planned schedule). Twenty-two patients were evaluable. The treatment completion rate was 100% (95% confidence interval 85-100). The response rate 8 weeks post-radiotherapy was 82% (95% confidence interval 60-95). The most common grade 3/4 treatment-emergent adverse events were mucosal inflammation (73%); dermatitis (27%); and infection, radiation skin injury and stomatitis (23% each). Cetuximab plus concomitant boost radiotherapy can be safely administered to Japanese patients with locally advanced squamous cell carcinoma of the head and neck. Tolerability and efficacy were in line with those reported in the Phase III Bonner trial in a Western population of patients with locally advanced squamous cell carcinoma of the head and neck.

    Human papillomavirus (HPV) has been implicated in the pathogenesis of a subset of oropharyngeal squamous cell carcinoma. As a result, traditional paradigms in relation to the management of head and neck squamous cell carcinoma have been changing. Research into HPV-related oropharyngeal squamous cell carcinoma is rapidly expanding, however many molecular pathological and clinical aspects of the role of HPV remain uncertain and are the subject of ongoing investigation. A detailed search of the literature pertaining to HPV-related oropharyngeal squamous cell carcinoma was performed and information on the topic was gathered. In this article, we present an extensive review of the current literature on the role of HPV in oropharyngeal squamous cell carcinoma, particularly in relation to epidemiology, risk factors, carcinogenesis, biomarkers and clinical implications. HPV has been established as a causative agent in oropharyngeal squamous cell carcinoma and biologically active HPV can act as a prognosticator with better overall survival than HPV-negative tumours. A distinct group of younger patients with limited tobacco and alcohol exposure have emerged as characteristic of this HPV-related subset of squamous cell carcinoma of the head and neck. However, the exact molecular mechanisms of carcinogenesis are not completely understood and further studies are needed to assist development of optimal prevention and treatment modalities.

    1993-01-01

    Squamous cell carcinoma antigen (SCC-A) in serum was serially measured during follow-up of 96 squamous cell carcinoma patients (75 head and neck cancers and 21 uterine cervical cancers), treated with radiotherapy. In 27 of the patients with head and neck cancer and in 12 of those with cervical cancer SCC-A had also been measured before radiotherapy. In this head and neck carcinoma group, the median level of SCC-A was 1.3 (95% CI: 1.2-1.9) ng/ml before radiotherapy and 1.4 (CI: 1.1-1.5) ng/ml after radiotherapy. In the cervical carcinoma group, the median SCC-A decreased significantly (p<0.001) from a pretreatment value of 7.5 (CI: 3.8-26.3) ng/ml to a posttreatment value of 0.9 (CI:<0.5-1.8) ng/ml. In the total group of 75 head and neck cancers 21 relapses occurred and in 4 of these the relapse was detected at a clinically silent stage by an elevation of serum SCC-A. The same was true for 4 of the 9 relapses that occurred in the total group of uterine cervical cancer. The study suggests that serum SCC-A may be useful for posttreatment monitoring of patients with uterine cervix cancer while its value in head and neck cancer probably is more marginal. (orig.)

    Vismodegib is a first-in-class agent targeting the hedgehog signaling pathway for treatment of patients with locally advanced basal cell carcinoma (BCC) and metastatic BCC. There have been concerns about the development of squamous cell carcinoma (SCC) in patients treated with this drug. We sought to determine whether treatment with vismodegib is associated with an increase in the risk of cutaneous SCC. In this retrospective cohort study, patients treated with vismodegib as part of phase I and II clinical studies were compared with participants from the University of California, San Francisco, Nonmelanoma Skin Cancer Cohort who received standard therapy for primary BCC. In total, 1675 patients were included in the analysis, and the development of SCC after vismodegib exposure was assessed. The use of vismodegib was not associated with an increased risk of subsequent development of SCC (adjusted hazard ratio, 0.57; 95% confidence interval, 0.28-1.16). Covariates including age, sex, history of previous nonmelanoma skin cancer, and number of visits per year were significantly associated with the development of SCC. A limitation of the study was that a historic control cohort was used as a comparator. Vismodegib was not associated with an increased risk of subsequent SCC when compared with standard surgical treatment of BCC. Copyright © 2017 American Academy of Dermatology, Inc.

    Full Text Available Abstract Objective To explore the role of Major Vault Protein (MVP in oral cavity squamous cell carcinoma patients. Subjects and Methods 131 consecutive patients suffering from oral cavity squamous cell carcinoma were included in the study. In the whole series, the mean follow-up for survivors was 123.11 ± 40.36 months. Patients in tumour stages I and II were referred to surgery; patients in stage III-IV to postoperative radiotherapy (mean dose = 62.13 ± 7.74 Gy in 1.8–2 Gy/fraction. MVP expression was studied by immunohistochemistry in paraffin-embedded tumour tissue. Results MVP expression was positive in 112 patients (85.5% and no relation was found with clinic pathological variables. MVP overexpression (those tumours with moderate or strong expression of the protein was related to insulin-like growth factor receptor-1 (IGF-1R expression (P = 0.014. Tumour stage of the disease was the most important prognostic factor related to survival. Tumours overexpressing MVP and IGF-1R were strongly related to poor disease-free survival (P = 0.008, Exp(B = 2.730, CI95% (1.302-5.724 and cause-specific survival (P = 0.014, Exp(B = 2.570, CI95% (1.215-5.437 in patients achieving tumour stages III-IV, in multivariate analysis. Conclusions MVP and IGF-1R expression were related in oral squamous cell carcinoma and conferred reduced long-term survival in patients suffering from advanced stages of the disease.

  13. Management of metastatic renal cell carcinoma in patients with poor prognosis

    Bullock, Andrea; McDermott, David F; Atkins, Michael B

    2010-01-01

    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

  14. A Case of Nonhealing Leg Ulcer: Basal Cell Carcinoma

    Directory of Open Access Journals (Sweden)

    Didem Didar Balcı

    2008-06-01

    Full Text Available A 75-year-old woman was admitted to our outpatient clinic with a three-year history of a painless, nonhealing ulcer located on the left lower leg. She had no response to previous therapy with local wound care. Skin examination revealed an ulcer 2.7 x 3.7 cm in size, and the surrounding skin showed minimal erythema. The surface of the ulcer demonstrated shiny granulation tissue. Biopsy of the ulcer edge and base showed basal cell carcinoma. Venous Doppler ultrasonography and dermatological examination did not reveal chronic venous insufficiency. Basal cell carcinomas rarely arise from previous long-term ulcers or developing de novo. We suggest that patients who develop non-healing leg ulcers, should be examined for basal cell carcinoma.

    We studied the production of heterophile antinuclear antibodies (ANAs) in the sera of 50 patients, 20 with nasopharyngeal carcinoma (NPC) and 30 with other head and neck cancers (laryngeal cancer and maxillary cancer), before and after radiation therapy. A higher incidence of ANAs was found in the sera of patients with NPC and ANA production in these patients was higher after radiation therapy. We therefore performed in vitro experiments to explore the mechanisms of ANA production in the serum of postirradiated NPC patients. X-ray-irradiated NPC-derived cells (NPC-KT) produced a large amount of Epstein-Barr virus (NPC EBV) compared with non-irradiated NPC-KT cells. Nasopharyngeal carcinoma EBV-infected lymphocytes produced high levels of ANAs. These data suggest that lymphocytes infected by EBV from NPC cells may produce ANAs in the sera of NPC patients.

    Despite improvements in surgical techniques and treatments introduced into clinical practice, the overall survival of patients with esophageal squamous cell carcinoma remains low. Several epidermal growth factor receptor inhibitors are being evaluated in the context of clinical trials, but there is little evidence of effectiveness in real-world conditions. This study aimed at assessing the effectiveness of nimotuzumab combined with onco-specific treatment in Cuban real-life patients with locally advanced or metastatic esophageal squamous cell carcinoma. A comparative and retrospective effectiveness study was performed. The 93 patients treated with nimotuzumab were matched, with use of propensity score matching, with patients who received a diagnosis of locally advanced or metastatic squamous cell carcinoma of the esophagus in three Cuban provinces reported between 2011 and 2015 to the National Cancer Registry. The Kaplan-Meier method was used to estimate event-time distributions. Log-rank statistics were used for comparisons of overall survival between groups. A two-component mixture model assuming a Weibull distribution was fitted to assess the effect of nimotuzumab on short-term and long-term survival populations. There was an increase in median overall survival in patients treated with nimotuzumab (11.9 months versus 6.5 months without treatment) and an increase in the 1-year survival rate (54.0% versus 21.9% without treatment). The 2-year survival rates were 21.1% for patients treated with nimotuzumab and 0% in the untreated cohort. There were statistically significant differences in survival between groups treated and not treated with nimotuzumab, both in the short-term survival population (6.0 months vs 4.0 months, p = 0.009) and in the long-term survival population (18.0 months vs 11.0 months, p = 0.001). Our study shows that nimotuzumab treatment concurrent with chemoradiotherapy increases the survival of real-world patients with locally advanced

    The objective of this study was to investigate therapeutic strategies for oropharyngeal squamous cell carcinoma based on an examination of clinical outcomes in our department. The patients were 99 cases with oropharyngeal squamous cell carcinoma treated in our hospital from March 2000 to March 2009. Five-year overall survival (OS) and 5-year cause-specific survival (CSS) were examined by the Kaplan-Meier survival curve. Subsite, stage, treatment (surgery group or radiotherapy or/and chemotherapy group) and prognosis were reviewed retrospectively. Five-year OS and 5-year CSS were 50% and 59%. Compared with the Stage I and II groups, the prognosis of Stage III and IV groups was significantly worse. As for the treatment, 5-year CSS of the surgery group was 76%, while that of the radiotherapy or/and chemotherapy group was 52%. Regarding the subsite, 5-year CSS of the lateral wall type Stage I and II groups was 90% (surgery group: 100%, radiotherapy or/and chemotherapy group: 83%), and that of the Stage III and IV groups was 63% (surgery group: 87%, radiotherapy or/and chemotherapy group: 55%). Five-year CSS of the superior wall type Stage I and II groups was 85% (surgery group: 100%, radiotherapy or/and chemotherapy group: 66%), and that of the Stage III and IV groups was 50% (surgery group: 75%, 5-year CSS was not obtained in the radiotherapy or/and chemotherapy group). The good outcome of the surgery group suggests that the indications for the operation were appropriate, and expansion of transoral resection should be considered in the near future. The outcomes of the radiotherapy or/and chemotherapy group require improvement. (author)

    To predict the incidence of moderate-to-severe patient-reported xerostomia among head and neck squamous cell carcinoma (HNSCC) and nasopharyngeal carcinoma (NPC) patients treated with intensity-modulated radiotherapy (IMRT). Multivariable normal tissue complication probability (NTCP) models were developed by using quality of life questionnaire datasets from 152 patients with HNSCC and 84 patients with NPC. The primary endpoint was defined as moderate-to-severe xerostomia after IMRT. The numbers of predictive factors for a multivariable logistic regression model were determined using the least absolute shrinkage and selection operator (LASSO) with bootstrapping technique. Four predictive models were achieved by LASSO with the smallest number of factors while preserving predictive value with higher AUC performance. For all models, the dosimetric factors for the mean dose given to the contralateral and ipsilateral parotid gland were selected as the most significant predictors. Followed by the different clinical and socio-economic factors being selected, namely age, financial status, T stage, and education for different models were chosen. The predicted incidence of xerostomia for HNSCC and NPC patients can be improved by using multivariable logistic regression models with LASSO technique. The predictive model developed in HNSCC cannot be generalized to NPC cohort treated with IMRT without validation and vice versa. PMID:25163814

    Full Text Available Squamous cell carcinoma of the ovary is a rare condition and usually arises in mature cystic teratoma (MCT or dermoid cyst of the ovary. The reported incidence of malignant transformation in MCT is approximately 2%. A case of squamous cell carcinoma arising in a dermoid cyst of the ovary presenting at an early stage is presented here. A 53-year-old postmenopausal lady, presented with the complaint of pain in right lower abdomen since one month and a large complex abdomino-pelvic mass on examination and investigations. Final histopathology was reported as squamous cell carcinoma of left ovary arising from dermoid cyst and a benign dermoid cyst in the right ovary. The patient was assigned to squamous cell carcinoma of the ovary arising in a mature cystic teratoma, surgical stage Ic2. In view of the poor prognosis, adjuvant chemotherapy was started.

    There has been much discussion recently about the risk category of tall cell variant (TVC) histology and its effects on the management of papillary thyroid carcinoma (PTC). We, therefore, undertook a retrospective study to compare stage-matched risk factors and recurrence rates between classical PTC (cPTC) patients and patients with TCV histology. A total of 3128 well-differentiated thyroid carcinoma patients who were treated and followed-up for more than 5 years in our clinic from 1995 to 2016 were included in this study. There were 2783 PTC (89%) patients, 1113 (40%) of them were cPTC and 56 (2%) of them were TCV patients. In all stages, the stage-matched incidence of extrathyroidal extension (ETE), lymphovascular invasion and initial lymph node metastases were significantly higher in TCV patients than in cPTC patients (Papproach and closer follow-up than classical patients.

    2016-01-01

    Spindle Cell Carcinoma (SpCC), also known as Sarcomatoid Carcinoma, is a rare and peculiar biphasic malignant neoplasm that occurs mainly in the upper aero-digestive tract, mostly in larynx. SCC accounts for 3% of all squamous cell carcinomas (SCCs) in the head and neck region. It is a rare variant of SCC which shows spindled or pleomorphic tumour cells simulating a true sarcoma. We present a case report of SpCC nasal cavity in a 50-year-old female patient, presented with intermittent epistaxis from left nasal cavity. On physical examination, the patient had an ulcero-exophytic type of mass in the left nasal cavity and a smooth bulge on the left side of anterior hard palate. Patient underwent excision of nasal mass along with partial palatectomy by facial degloving approach and reconstruction of palate with naso-labial flap. The postoperative histopathological report showed SCC. Surgery forms the mainstay of treatment. Radiotherapy and Chemotherapy is warranted in order to improve treatment results. As only few cases have been reported, we report a case of this rare entity to contribute for better understanding and awareness of this rare malignancy. PMID:27190843

    Highlights: • This study generates a monoclonal antibody CA27 against the mycoplasmal p37 protein. • CA27 isolates circulating tumor cells (CTCs) from the blood of liver cancer patients. • Results show the first evidence for mycoplasma infected-CTCs in cancer patients. - Abstract: Many studies have shown that persistent infections of bacteria promote carcinogenesis and metastasis. Infectious agents and their products can modulate cancer progression through the induction of host inflammatory and immune responses. The presence of circulating tumor cells (CTCs) is considered as an important indicator in the metastatic cascade. We unintentionally produced a monoclonal antibody (MAb) CA27 against the mycoplasmal p37 protein in mycoplasma-infected cancer cells during the searching process of novel surface markers of CTCs. Mycoplasma-infected cells were enriched by CA27-conjugated magnetic beads in the peripheral blood mononuclear cells in patients with hepatocellular carcinoma (HCC) and analyzed by confocal microscopy with anti-CD45 and CA27 antibodies. CD45-negative and CA27-positive cells were readily detected in three out of seven patients (range 12–30/8.5 ml blood), indicating that they are mycoplasma-infected circulating epithelial cells. CA27-positive cells had larger size than CD45-positive hematological lineage cells, high nuclear to cytoplasmic ratios and irregular nuclear morphology, which identified them as CTCs. The results show for the first time the existence of mycoplasma-infected CTCs in patients with HCC and suggest a possible correlation between mycoplasma infection and the development of cancer metastasis.

  6. HPV Carcinomas in Immunocompromised Patients

    Full Text Available Human papillomavirus (HPV infection is the most common sexually transmitted disease worldwide and can result in pre-malignancies or overt malignancies of the skin and mucosal surfaces. HPV-related illnesses are an important personal and public health problem causing physical, mental, sexual and financial detriments. Moreover, this set of malignancies severely affects the immunosuppressed population, particularly HIV-positive patients and organ-transplant recipients. There is growing incidence of HPV-associated anogenital malignancies as well as a decrease in the average age of affected patients, likely related to the rising number of high-risk individuals. Squamous cell carcinoma is the most common type of HPV-related malignancy. Current treatment options for HPV infection and subsequent disease manifestations include imiquimod, retinoids, intralesional bleomycin, and cidofovir; however, primary prevention with HPV vaccination remains the most effective strategy. This review will discuss anogenital lesions in immunocompromised patients, cutaneous warts at nongenital sites, the association of HPV with skin cancer in immunocompromised patients, warts and carcinomas in organ-transplant patients, HIV-positive patients with HPV infections, and the management of cutaneous disease in the immunocompromised patient.

    Merkel cell carcinoma is an aggressive skin malignancy. Primary Merkel cell carcinomas are treated by wide radical excision with or without adjuvant radiotherapy, while benefits of adjuvant chemotherapy remain doubtful. There are only several cases of gastrointestinal metastases of Merkel cell carcinoma reported so far. We report a case of recurrent Merkel cell carcinoma with metastases to the stomach and the small intestines after wide excision of primary Merkel cell carcinoma.

    Regardless of advances in diagnosis and treatment during the past 40 years, the overall 5-year survival rates for oral and oropharyngeal squamous cancers have only slightly improved and remain around 50%. Thus, the early diagnosis and treatment of carcinoma by health care providers are essential in achieving a good prognosis. We report a case of invasive squamous cell carcinoma that presented as a benign endodontic-periodontic lesion with a 7-mm periodontal pocket on tooth #15 in a 40-year-old, non-smoking woman. The subsequent management of the case is also discussed. The study was conducted in accordance with the Helsinki Declaration of 1975, as revised in 2000. Our patient was seen for a comprehensive periodontal examination including a periodontal charting, occlusal analysis, study casts, electronic pulp test for tooth #15, and complete mouth periapical radiographs. As there was a periapical radiolucency, an endodontic consultation was obtained. A periodontal flap surgical procedure was performed on teeth #13 to #15, and as there was bone erosion into the maxillary sinus, a biopsy of the soft tissue was submitted to the local hospital for histological analysis. The biopsied lesion was diagnosed as invasive, moderately differentiated squamous cell carcinoma with focal spindle and clear cell differentiation (grade II to III of IV). Bone invasion was also identified. The treatment of the carcinoma involved a hemimaxillectomy with the removal of the maxillary left posterior teeth. The patient remained free of tumor for 5 years after the initial presentation. Patient education and periodic oral cancer examinations by dental professionals are necessary to reduce diagnostic delay and improve prognosis. This case report emphasizes the important role of dental professionals, especially periodontists and endodontists, of being aware that squamous cell carcinoma may manifest itself clinically and/or radiographically as a common periodontal or endodontic lesion.

    Positive nodal status (pN1) is an independent predictor of survival in renal cell carcinoma (RCC) patients. However, no study to date has tested whether the location of lymph node (LN) metastases does affect oncologic outcomes in a population submitted to radical nephrectomy (RN) and extended lymph node dissection (eLND). To describe nodal disease dissemination in clear cell RCC (ccRCC) patients and to assess the effect of the anatomical sites and the number of nodal areas affected on cancer specific mortality (CSM). The study included 415 patients who underwent RN and eLND, defined as the removal of hilar, side-specific (pre/paraaortic or pre/paracaval) and interaortocaval LNs for ccRCC, at two institutions. Descriptive statistics were used to depict nodal dissemination in pN1 patients, stratified according to nodal site and number of involved areas. Multivariable Cox regression analyses and Kaplan-Meier curves were used to explore the relationship between pN1 disease features and survival outcomes. Median number of removed LN was 14 (IQR 9-19); 23% of patients were pN1. Among patients with one involved nodal site, 54 and 26% of patients were positive only in side-specific and interaortocaval station, respectively. The most frequent nodal site was the interaortocaval and side-specific one, for right and left ccRCC, respectively. Interaortocaval nodal positivity (HR 2.3, CI 95%: 1.3-3.9, p < 0.01) represented an independent predictor of CSM. When ccRCC patient harbour nodal disease, its spreading can occur at any nodal station without involving the others. The presence of interoartocaval positive nodes does affect oncologic outcomes. Lymph node invasion in patients with clear cell renal cell carcinoma is not following a fixed anatomical pattern. An extended lymph node dissection, during treatment for primary kidney tumour, would aid patient risk stratification and multimodality upfront treatment.

    Objectives To analyze the epidemiology and describe the prognostic indicators of patients with primary squamous cell carcinoma of the thyroid. Study Design and Setting Retrospective cohort study based on a national database. Methods The US National Cancer Institute's SEER registry (Surveillance, Epidemiology, and End Results) was reviewed for patients with primary squamous cell carcinoma of the thyroid from 1973 to 2012. Study variables included age, sex, race, tumor size, tumor grade, regional and distant metastases, and treatment modality. Survival measures included overall survival (OS) and disease-specific survival (DSS). Results A total of 199 cases of primary squamous cell carcinoma of the thyroid were identified. Mean age at diagnosis was 68.1 years; 58.3% were female; and 79.4% were white. Following diagnosis, 46.3% of patients underwent surgery; 55.7%, radiation therapy; and 45.8%, surgery with radiation therapy. Kaplan-Meier analysis demonstrated OS and DSS of 16% and 21% at 5 years, respectively. Median survival after diagnosis was 9.1 months. Multivariate Cox regression analysis showed that predictors of OS and DSS included age ( P Squamous cell carcinoma of the thyroid is a rare malignancy with a very poor prognosis. Surgical resection confers an overall survival benefit. Age, tumor grade, and tumor size are predictors of OS and DSS.

HCC generally has a more aggressive clinical behavior compared with the other differentiated thyroid cancers, and it is associated with a higher rate of distant metastases. Minimally invasive HCC demonstrates much less aggressive behavior; lesions <4 cm can be treated with thyroid lobectomy alone, and without radioactive iodine (RAI. HCC has been observed to be less iodine-avid compared with other differentiated thyroid cancers; however, recent data have demonstrated improved survival with RAI use in patients with HCC >2 cm and those with nodal and distant metastases. Patients with localized iodine-resistant disease who are not candidates for a wait-and-watch approach can be treated with localized therapies. Systemic therapy is reserved for patients with progressive, widely metastatic HCC. Keywords: thyroid cancer, thyroid nodule, follicular cell carcinoma, Hurthle cell lesion, minimally invasive HCC

    Full Text Available Human papillomavirus (HPV infection has been demonstrated in some of the nonmelanoma skin cancers as well as in precancerous lesions. Multiple infections of mucosal high-risk HPV may contribute to the onset of digital Bowen's disease through, if any, digital-genital transmission. We screened for the presence of the mucosal HPV DNA in patients with extragenital Bowen's disease (, squamous cell carcinoma (, bowenoid papulosis (, verrucous carcinoma (, actinic keratosis (, and basal cell carcinoma (. We used a PANArray HPV Genotyping Chip for high-risk and low-risk mucosal types. Genotyping data was confirmed using a conventional direct DNA sequencing method. Two cases of extragenital Bowen's disease were positive for types 16 and 33 of mucosal HPV, respectively. None of the squamous cell carcinoma cases were positive. Neither patients with digital Bowen's disease ( nor those with squamous cell carcinoma ( showed any mucosal high-risk HPV. Mucosal high-risk HPV DNA was confirmed in 5 (55.6% of the 9 patients with bowenoid papulosis. HPV 16 was most prevalent (, while the DNA of HPVs 35 and 67 was detected in one sample for each of the two types. Our study demonstrated that two (6.7% of the patients with 30 extragenital Bowen's disease were positive for types 16 and 33 of mucosal HPV, respectively. HPVs belonging to the mucosal high-risk group may participate in the development of extragenital Bowen's disease. However, we could not find any relationship between the mucosal high-risk HPV and Bowen's disease or squamous cell carcinoma in the fingers.

    The differentiation between renal cell carcinoma(RCC) and transitional cell carcinoma(TCC) is important due to the different methods of treatment and prognosis. But occasionally it is difficult to draw a distinction between the two diseases when renal parenchyma and renal collecting systems are invaded simultaneously. We reviewed CT scans of 37 cases of renal cell carcinoma and 12 cases of transitional cell carcinoma which showed involvement of renal parenchyma and renal sinus fat on CT. Retrospective analysis was performed by 3 abdominal radiologists. Check points were renal contour bulging or reinform shape, location of mass center, intact parenchyma overlying the tumor, cystic change, calcification, LN metastasis, vessel invasion, and perirenal extention. There were renal contour bulging due to the tumor mass in 33 out of 37 cases of renal cell carcinoma, where a and nine of 12 cases of transitional cell carcinoma maintained the reinform appearance. This is significant statiscal difference between the two(P<0.005). Center of all TCCs were located in the renal sinus, and 24 out of 35 cases of RCC were located in the cortex(P<0.005). Thirty-six out of 37 cases of RCC lost the overlying parenchyma, where as 4 out of 9 cases of well enhanced TCC had intact overlying parenchyma(P<0.005) RCC showed uptic change within the tumor mags in 31 cases which was significanity higher than the 4 cases in TCC(P<0.05). CT findings of renal cell carcinoma are contour bulging, peripheral location, obliteration of parenchyma, and cystic change. Findings of transitional cell carcinoma are reinform appearance, central location within the kidney, intact overlying parenchyma, and rare cystic change

    Dioctophyma renale (D. renale), or giant kidney worms, are the largest nematodes that infect mammals. Approximately 20 cases of human infection have been reported. We present a case of a 71-year-old man with a recent history of unintentional weight loss and painless haematuria, passing elongated erythematous tissue via his urethra. CT revealed a left renal mass with pulmonary nodules and hepatic lesions. On microscopy, the erythematous tissue passed was identified as D. renale. On subsequent renal biopsy, pathology was consistent with renal cell carcinoma. This is the first reported case of concomitant D. renale infection and renal cell carcinoma, and the second reported case of D. renale infection of the left kidney alone. 2016 BMJ Publishing Group Ltd.

    Introduction. Tattoos have increasingly become accepted by mainstream Western society. As a result, the incidence of tattoo-associated dermatoses is on the rise. The presence of a poorly differentiated squamous cell carcinoma in an old tattooed skin is of interest as it has not been previously documented. Case Presentation. A 79-year-old white homeless man of European descent presented to the dermatology clinic with a painless raised nodule on his left forearm arising in a tattooed area. A biopsy of the lesion revealed a poorly differentiated squamous cell carcinoma infiltrating into a tattoo. The lesion was completely excised and the patient remains disease-free one year later. Conclusion. All previous reports of squamous cell carcinomas arising in tattoos have been well-differentiated low-grade type or keratoacanthoma-type and are considered to be coincidental rather than related to any carcinogenic effect of the tattoo pigments. Tattoo-associated poorly differentiated invasive carcinoma appears to be extremely rare. PMID:21274289

    Mast cells and eosinophils are increased in oral squamous cell carcinoma. The significance of such an association has been variably thought to be either a potential diagnostic tool for stromal invasion or as a prognostic indicator. The aim of the study was to study the mast cells and eosinophils between normal oral mucosa, leukoplakia and oral squamous cell carcinoma and to study the significance of mast cells in the progression of the lesion. A retrospective study was done on archival tissue received from January 2015 to December 2015, in the Department of Oral Pathology, RUHS College of Dental Sciences, Jaipur, Rajasthan, India. Seventy (70) cases were studied (30 cases each of leukoplakia and carcinoma and 10 cases of control group), sections were stained with toluidine blue solution to reveal mast cells. Eosinophils were studied in Haematoxylin & Eosin stained sections. Mast cell density significantly increased from: normal mucosa to oral leukoplakia to carcinoma, suggesting a role of the mast cells in the development of these lesions. The higher eosinophil counts in carcinoma group compared to dysplasia group proved that they might have a role in stromal invasion. The assessment of these could become, in the future, useful for therapeutic approaches in this subset of the patient.

    Recent years have brought an enhanced understanding of Merkel cell carcinoma (MCC) biology, especially with regard to the Merkel cell polyoma virus as a causative agent. Differences between Merkel cell polyomavirus-positive and Merkel cell polyomavirus-negative MCC in morphology; gene expression, miRNA profiles and prognosis have been reported. Origin of MCC is controversial. Presence of neurosecretory granules has suggested that these carcinomas originate from one of the neurocrest derivatives, most probably Merkel cells; the name Merkel cell carcinoma is now widely accepted. Expression of PGP 9.5, chromogranin A and several neuropeptides, initially regarded as specific markers for neural and neuroendocrine cells, has recently been shown in a subset of lymphomas. MCC commonly expresses terminal deoxynucleotidyl transferase and PAX5. Their co-expression under physiologic circumstances is restricted to pro/pre-B cells and pre-B cells. These findings lead to the hypothesis by zur Hausen et al. that MCC originates from early B cells. This review was intended to critically appraise zur Hausen's hypothesis and discuss the possibility that MCC is a heterogenous entity with distinct subtypes. © 2014 John Wiley & Sons A/S.

    Full Text Available Basal Cell Carcinoma is the most common human malignant neoplasm. Vulvar basal cell carcinoma is rare, accounting for less than 5% of all vulvar neoplasms. Vulvar basal cell carcinomas are usually diagnosed late because they are often asymptomatic and tend to grow at slow rates. They are usually diagnosed late because they are often asymptomatic. However, these tumours may appear in areas which are normally covered with ultraviolet light. We present the case of a 60 years old woman diagnosed with invasive breast cancer for which she underwent surgery followed by chemotherapy and radiotherapy. The patient presented to our department with an ulcerated vulvar lesion. On inspection, the tumour measured 3/2 cm and was located on the left labium majus. The biopsy confirmed the diagnosis of vulvar basal cell carcinoma and a wide local excision was performed with no relapse at one year. In conclusion, early detection of BCC’s is critical to allow complete surgical cure so any abnormality on the vulva should be biopsied. A wide safety margin of 1cm should be achieved when resecting the tumour and the physician should keep in mind that the BCC’s of the vulva has a high recurrence rate. Previous chemotherapy is not associated with this type of non-melanoma skin cancer.

    Full Text Available OBJECTIVE: To report our experience with laparoscopic-assisted nephroureterectomy for upper tract transitional cell carcinomas after radical cystectomy and urinary diversion. MATERIALS AND METHODS: Seven patients (53-72 years-old underwent laparoscopic-assisted nephroureterectomy 10 to 53 months after radical cystectomy for transitional cell carcinoma at our institution. Surgical technique, operative results, tumor features, and outcomes of all patients were retrospectively reviewed. RESULTS: Mean operative time was 305 minutes with a significant amount of time spent on the excision of the ureter from the urinary diversion. Estimate blood loss and length of hospital stay averaged 180 mL and 10.8 days, respectively. Intraoperative and postoperative complications occurred in two patients each. There was one conversion to open surgery. Pathology confirmed upper-tract transitional cell carcinoma in all cases. Metastatic disease occurred in two patients after a mean follow-up of 14.6 months. CONCLUSIONS: Nephrouretectomy following cystectomy is a complex procedure due to the altered anatomy and the presence of many adhesions. A laparoscopic-assisted approach can be performed safely in properly selected cases but does not yield the usual benefits seen with other laparoscopic renal procedures.

    Full Text Available Background: Basaloid squamous cell carcinoma of oral mucosa is a rare and aggressive variant of squamous cell carcinoma. They can be differentiated from squamous cell carcinomas by their distinct clinical and histopathological features. Methods: 45 year old female patient presented with extra oral exophytic mass and intra-oral ulcerative lesion on right buccal mucosa and vestibule. The patient was referred for routine blood examination and radiography followed by incisional biopsy. The biopsy specimen was fixed, processed and stained with Hematoxylin and Eosin for further microscopic examination. Results: On microscopic examination basaloid cells were seen proliferating along with dysplastic squamous cells in the connective tissue stroma. Conclusion: Based on the histopathological findings a diagnosis of ′Basaloid squamous cell carcinoma′ was made. The patient was referred to department of Oral and Maxillofacial Surgery for excision of the lesion followed by radiotherapy.

    The renal cell cancer incidence is relatively low in younger patients, encompassing 3% to 7% of all renal cell cancers. While young patients may have renal tumors due to hereditary syndromes, in some of them sporadic renal cancers develop without any family history or known genetic mutations. Our recent observations from clinical practice have led us to hypothesize that there is a difference in histological distribution in younger patients compared to the older cohort. We queried the SEER (Surveillance, Epidemiology and End Results) 18-registry database for all patients 20 years old or older who were surgically treated for renal cell carcinoma between 2001 and 2008. Patients with unknown race, grade, stage or histology and those with multiple tumors were excluded from study. Four cohorts were created by dividing patients by gender, including 1,202 females and 1,715 males younger than 40 years old, and 18,353 females and 30,891 males 40 years old or older. Chi-square analysis was used to compare histological distributions between the cohorts. While clear cell carcinoma was still the most common renal cell cancer subtype across all genders and ages, chromophobe renal cell cancer was the most predominant type of nonclear renal cell cancer histology in young females, representing 62.3% of all nonclear cell renal cell cancers (p renal cell cancer remained the most common type of nonclear renal cell cancer. It is possible that hormonal factors or specific pathway dysregulations predispose chromophobe renal cell cancer to develop in younger women. We hope that this work provides some new observations that could lead to further studies of gender and histology specific renal tumorigenesis.

    Prognosis of advanced oral squamous cell carcinoma remains a challenge for clinicians despite progress in its diagnosis and treatment over the past decades. In this review, we assessed clinicopathological factors and potential biomarkers along with their prognostic relevance in an attempt to develop optimal treatment strategies for these patients. In addition to several pathologic factors that have been proposed to improve prognostic stratification and treatment planning in the eighth edition of the American Joint Committee staging manual on cancer, we reviewed some other imaging and clinicopathological parameters demonstrated to be closely associated with patient prognosis, along with the biomarkers related to novel target or immune therapy. Evaluation of current literature regarding the prognostic stratification used in contemporary clinicopathological studies and progress in the development of targeted or immune therapy may help these patients benefit from tailored and personalized treatment and obtain better oncological results.

    Radioresistance often leads to poor survival in concurrent chemoradiotherapy-treated cervical squamous cell carcinoma, and reliable biomarkers can improve prognosis. We compared the prognostic potential of hemoglobin, absolute neutrophil count, and absolute lymphocyte count with that of squamous cell carcinoma antigen in concurrent chemoradiotherapy-treated squamous cell carcinoma. We analyzed 152 patients with concurrent chemoradiotherapy and high-dose-rate intracavitary brachytherapy-treated cervical squamous cell carcinoma. Hemoglobin, absolute neutrophil count, absolute lymphocyte count, and squamous cell carcinoma antigen were quantitated and correlated with survival, using Cox regression, receiver operating characteristic curve analysis, and Kaplan-Meier plots. Both hemoglobin and absolute lymphocyte count in the second week of concurrent chemoradiotherapy (Hb2 and ALC2) and squamous cell carcinoma antigen in the third week of concurrent chemoradiotherapy (mid-squamous cell carcinoma antigen) correlated significantly with disease-specific survival and progression-free survival. The ratio of high-dose-rate intracavitary brachytherapy dose to total dose (high-dose-rate intracavitary brachytherapy ratio) correlated significantly with progression-free survival. Patients with both low Hb2 (≤11 g/dL) and ALC2 (≤639 cells/µL) showed a lower 5-year disease-specific survival rate than those with high Hb2 and/or ALC2, regardless of mid-squamous cell carcinoma antigen (mid-squamous cell carcinoma antigen: ≤4.7 ng/mL; 5-year disease-specific survival rate: 85.5% vs 94.6%, p = 0.0096, and mid-squamous cell carcinoma antigen: >4.7 ng/mL; 5-year disease-specific survival rate: 43.8% vs 66.7%, p = 0.192). When both Hb2 and ALC2 were low, the low high-dose-rate intracavitary brachytherapy ratio (≤0.43) subgroup displayed significantly lower 5-year disease-specific survival rate compared to the subgroup high high-dose-rate intracavitary brachytherapy ratio (>0

    Objectives: To evaluate quality of life (QOL) in patients with squamous cell carcinoma of oral and oropharyngeal region. Methodology: This is prospective longitudinal study was conducted at ENT department Dow University Hospital and Radiotherapy Department KIRAN from November 2012 to November 2015. It included 56 patients of squamous cell carcinoma (SCC) of oral cavity and oropharynx regions who had completed cancer treatment (Wide local excision +/-Neck dissection +/- Radiotherapy). UW QOL questionnaire is taken as the tool to analyze the quality improvement in the domains of pain, appearance, activity, recreation, swallowing, chewing, speech, shoulder, taste, saliva, mood and anxiety. Comparative analysis used to assess all 12 factors associated with cancer patients. A paired t-test was used to compare preoperative and 6 months or more post-operative QOL rating. Results: Six months or more after surgery, 13 patients were lost to follow up and 9 died. 34 patients completed the UW QOL. Cancer Survivors presented overall significantly poorer QOL. QOL improved in the domains of activity, shoulder pain, mood and anxiety. Conclusion: This study recommend Quality of life assessment of oral and oropharyngeal cancers which may contribute to functional, psychological and somatic limitations and likely alter the treatment methodology where cure of cancer is equally good for any modality. This study also identifies that cases of early cancer of oral and oropharyngeal region would not compromise QOL of the patients significantly. (author)

    Ubiquitin-specific protease 14, a deubiquitinating enzyme, has been implicated in the tumorigenesis and progression of several cancers, but its role in oral squamous cell carcinoma remains to be elucidated. The aim of this study was to explore the expression pattern and roles of Ubiquitin-specific protease 14 in the occurrence and development of oral squamous cell carcinoma. Interestingly, Ubiquitin-specific protease 14 was overexpressed in oral cancer tissues and cell lines at both mRNA and protein levels. b-AP15, a specific inhibitor of Ubiquitin-specific protease 14, significantly inhibited the growth of cancer cells and increased cell apoptosis in a dose-dependent manner. Moreover, knockdown of Ubiquitin-specific protease 14 by shRNA significantly inhibited the proliferation and migration of cancer cells in vitro. Finally, using a xenograft mouse model of oral squamous cell carcinoma, knockdown of Ubiquitin-specific protease 14 markedly inhibited tumor growth and triggered the cancer cell apoptosis in vivo, supporting previous results. In conclusion, for the first time we have demonstrated the expression pattern of Ubiquitin-specific protease 14 in oral squamous cell carcinoma and verified a relationship with tumor growth and metastasis. These results may highlight new therapeutic strategies for tumor treatment, application of Ubiquitin-specific protease 14 selective inhibitor, such as b-AP15, or knockdown by shRNA. Collectively, Ubiquitin-specific protease 14 could be a potential therapeutic target for oral squamous cell carcinoma patients. Copyright © 2016 Elsevier Ltd. All rights reserved.

    There are still controversies about the therapeutic strategies and subsequent outcome in head and neck Merkel cell carcinoma. Clinicopathological data of 23 Merkel cell carcinomas, 93 cutaneous head and neck squamous cell carcinomas (HNSCCs), 126 malignant melanomas, and 91 primary parotid gland carcinomas were comprehensively analyzed. Merkel cell carcinomas were cytokeratin 20 (CK20)/neuron-specific enolase (NSE)/chromogranin A (CgA)/synaptophysin (Syn)/thyroid transcription factor-1 (TTF-1)/MIB1 immunostained. All Merkel cell carcinomas underwent wide local excision. Parotidectomy/neck dissection was performed in 40%/33% cutaneous Merkel cell carcinoma and 100%/100% in parotid gland Merkel cell carcinoma. Five-year recurrence-free interval (RFI)/overall survival (OS) was significantly higher in malignant melanoma (81/80%) than in cutaneous Merkel cell carcinoma/HNSCC. Interestingly, 5-year RFI/OS was significantly higher in Merkel cell carcinoma (61%/79%) than in HNSCC (33%/65%; p Merkel cell carcinoma and parotid gland carcinomas, nor in the immunohistochemical profile. Five-year RFI/OS was significantly better in cutaneous Merkel cell carcinoma when compared with TNM classification matched HNSCC. Five-year RFI/OS was comparable in parotid gland Merkel cell carcinoma and other primary parotid gland malignancies. © 2016 Wiley Periodicals, Inc.

Patients undergoing radiotherapy for head and neck cancer are at increased risk of developing oral candidiasis and they more frequent have prior fungi colonization. Due to identification of specific risk factors predisposing to fungal infection in order to threat such patients the aim of this study was to determine the presence of Candida species in patients with oral squamous cell carcinoma and compare it to the control subjects (patients with benign oral mucosal lesions. Methods. A total number of 30 consecutive oral cancer examined patients were included in this prospective study (24 men and 6 women with a mean age of 61.47 years, range 41-81 years. The control group consisted of 30 consecutive patients with histologically proven benign oral mucosal lesions (16 men and 14 women with a mean age of 54.53 years, range 16- 83 years. The samples for mycological examination were obtained by using sterile cotton swabs from the cancer lesion surface and in the patients of the control group from the benign mucosal lesion surface. Samples were inoculated in Sabouraud' dextrose agar. For identification purposes, Mackenzie germ tube test was performend on all isolates. Results. The prevalence of Candida was significantly higher in oral cancer patients than in control subjects (χ2 = 5.455, p = 0.020. Candida was found on nine of the 30 cancer surfaces; 5 (16.7% were identified as non-albicans Candida and 4 (13.3% as Candida albicans. In the control group, only Candida albicans was isolated from 2 (6.7% patients. In this study, no statistically significant differences in the presence of Candida species was found with respect to gender, age, smoking, alcohol consumption, wearing of dental protheses and the site of cancer lesion. Conclusion. The increased prevalence of yeasts on the surfaces of oral carcinoma indicates a need for their

    Merkel cell carcinoma is a rare, aggressive skin cancer with poor prognosis in patients with advanced disease. Current standard care uses various cytotoxic chemotherapy regimens, but responses are seldom durable. Tumour oncogenesis is linked to Merkel cell polyomavirus integration and ultraviolet-radiation-induced mutations, providing rationale for treatment with immunotherapy antibodies that target the PD-L1/PD-1 pathway. We assessed treatment with avelumab, an anti-PD-L1 monoclonal antibody, in patients with stage IV Merkel cell carcinoma that had progressed after cytotoxic chemotherapy. In this multicentre, international, prospective, single-group, open-label, phase 2 trial, patients with stage IV chemotherapy-refractory, histologically confirmed Merkel cell carcinoma (aged ≥18 years) were enrolled from 35 cancer treatment centres and academic hospitals in North America, Europe, Australia, and Asia. Key eligibility criteria were an ECOG performance status of 0 or 1, measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, adequate haematological, hepatic, and renal function, and immune-competent status (patients with HIV, immunosuppression, haematological malignancies, and previous organ transplantation were excluded). Patient selection was not based on PD-L1 expression or Merkel cell polyomavirus status. Collection of biopsy material or use of archival tissue for these assessments was mandatory. Avelumab was given intravenously at a dose of 10 mg/kg every 2 weeks. The primary endpoint was confirmed objective response (complete response or partial response) assessed according to RECIST version 1.1 by an independent review committee. Safety and clinical activity were assessed in all patients who received at least one dose of study drug (the modified intention-to-treat population). This trial is registered with ClinicalTrials.gov as NCT02155647. Between July 25, 2014, and Sept 3, 2015, 88 patients were enrolled and received at

    Full Text Available Cervical carcinoma is the most common malignancy of the female genital tract and represents the second most common malignancy in women worldwide. Histologically 85 to 90% of cervical cancers are squamous cell carcinoma. Osteoclastic giant cell rich squamous cell carcinoma is an unusual histological variant of which only 4 cases have been reported. We present the case of a 49-year-old woman with a 6-month history of irregular vaginal bleeding. Examination revealed a 2.7 cm polypoid mass in the anterior lip of the uterine cervix. The patient underwent hysterectomy with bilateral salpingo-oophorectomy. Microscopically the tumor was composed of infiltrative nests of poorly differentiated nonkeratinizing squamous cell carcinoma. Interspersed in between these tumor cells were numerous osteoclastic giant cells with abundant eosinophilic cytoplasm devoid of nuclear atypia, hyperchromatism, or mitotic activity. Immunohistochemistry was performed; CK and P63 were strongly positive in the squamous component and negative in the osteoclastic giant cells, while CD68 and Vimentin were strongly positive in the giant cell population and negative in the squamous component. The patient received chemo- and radiotherapy for recurrent disease identified 3 months later on a follow-up CT scan; 7 months after the surgical procedure the patient is clinically and radiologically disease-free.

    Full Text Available Amruth R Palla, Donald Doll Department of Internal Medicine, Division of Hematology and Oncology, Ellis Fischel Cancer Center, University of Missouri, Columbia, MO, USA Abstract: Merkel cell carcinoma (MCC, a rare skin cancer, is associated with high mortality, especially in a metastatic setting. Though conventional chemotherapy with platinum and etoposide has had high response rates, many of the patients have had early relapse without any effective therapy thereafter. Recently, immune check point inhibitors have shown very good durable responses, leading to the approval of a programmed death-ligand 1 inhibitor Avelumab for these patients. We briefly review the epidemiology and immune basis of the pathogenesis of MCC, which therefore explains the excellent response to check point inhibitors, and throw light on future directions of immunotherapy for this cancer.

    Full Text Available We report a case of unexpected anal squamous cells carcinoma found in hemorrhoidectomy specimen. The patient had a 3-year history of prolapsing hemorrhoids. A prolapsing hemorrhoid was present at eleven o’clock in lithotomy. Milligan-Morgan was performed and gross examination of the specimen was unremarkable. Histopathologic evaluation showed noninvasive squamous cells carcinoma. The present case report evidences the opportunity of routine histopathologic analysis of hemorrhoidal specimens particularly in case of long-standing prolapse. Questions arise in the option of those techniques where no specimens are collected or tissue is excised far from deceased area.

    Full Text Available The use of sublobar resections as definitive management in stage I non-small cell lung carcinoma is a controversial topic in the medical community. We intend to report the latest developments and trends in relative indications for each of the above-mentioned surgical approaches for the treatment of stage I non-small cell lung carcinoma as well as the results of studies regarding local recurrence, disease-free survival and five-year survival rates. We reviewed 45 prospective and retrospective studies conducted over the last 25 years listed in the Pubmed and Scopus electronic databases. Trials were identified through bibliographies and a manual search in journals. Authors, citations, objectives and results were extracted. No meta-analysis was performed. Validation of results was discussed. Segmentectomies are superior to wedge resections in terms of local recurrences and cancer-related mortality rates. Sublobar resections are superior to lobectomy in preserving the pulmonary parenchyma. High-risk patients should undergo segmentectomy, whereas lobectomies are superior to segmentectomies only for tumors >2 cm (T2bN0M0 in terms of disease-free and overall 5-year survival. In most studies no significant differences were found in tumors <2 cm. Disease-free surgical margins are crucial to prevent local recurrences. Systematic lymphadenectomy is mandatory regardless of the type of resection used. In sublobar resections with less thorough nodal dissections, adjuvant radiotherapy can be used. This approach is preferable in case of prior resection. In pure bronchoalveolar carcinoma, segmentectomy is recommended. Sublobar resections are associated with a shorter hospital stay. The selection of the type of resection in T1aN0M0 tumors should depend on characteristic of the patient and the tumor. Patient age, cardiopulmonary reserve and tumor size are the most important factors to be considered. However further prospective randomized trials are needed to

    Three hundred and four patients with squamous cell carcinomas of the oral cavity were treated at the Finsen Institute in cooperation with the ENT-surgical departments between 1978 and 1982. The primary treatment consisted of radiotherapy alone in 74%, surgery alone in 4%, and a combination of radiotherapy and surgery in 15% of the patients. 2% received other treatment (cryotherapy), 5% did not complete the planned radiotherapy, and 1% were not treated at all. Of 203 patients with tumour remnant or first recurrence, 45% were operated, 2% received radiotherapy, and 2% combined treatment. This treatment strategy made 38% of the patients free of disease in the follow-up period (3 1/2 to 8 years) or until the patients died from other causes. Fifty-nine percent of the patients died from their oral carcinomas. Tumour size (T), lymph node status (N), and tumour stage were as expected important prognostic factors. (orig.)

    Cancer of the head and neck comprises a group of neoplasms that share a similar anatomical origin. Most originate from the epithelium of the aerodigestive tract and 90% correspond to squamous cell carcinoma. In the last 15 years, an increase in the incidence of squamous cell carcinoma induced by human papillomavirus (HPV) has been seen, mainly types 16 and 18, which are the most frequent found in cancers of the oral cavity and oropharynx, and types 6 and 11 in laryngeal cancer. There are reports in the literature that show HPV as the leading cause of oropharyngeal squamous cell carcinoma. Determine the prevalence of infection with high-risk HPV in patients diagnosed with squamous cell carcinoma of the oral cavity, oropharynx and larynx. An observational, cross-sectional, descriptive, unblinded study was performed. Prevalence of HPV infection was determined by polymerase chain reaction (PCR) in DNA samples from tumour tissue of patients with squamous cell carcinoma of the oral cavity, oropharynx and larynx. Typing was subsequently performed in HPV positive samples in order to detect types 18, 16, 11 and 6, using custom primers. A total of 45 patients were included. The association between laryngeal squamous cell carcinoma and HPV was established in two patients, which represented an overall prevalence of 4.4% in our population, and 10% for laringeal tumours. There is a low prevalence of HPV infection in squamous cell carcinoma of the oral cavity, oropharynx and larynx, in our population. Prospective studies on younger patients could provide more information. Copyright © 2016 Academia Mexicana de Cirugía A.C. Publicado por Masson Doyma México S.A. All rights reserved.

    2007-01-01

    The incidence of renal cell carcinoma is rising with the increased number of incidental detection of small tumours. During the past few years, percutaneous imaging-guided radiofrequency ablation has evolved as a minimally invasive treatment of small unresectable renal tumours offering reduced patient morbidity and overall health care costs. In radiofrequency ablation, thermal energy is deposited into a targeted tumour by means of a radiofrequency applicator. In recent studies, radiofrequency ablation was shown to be an effective and safe modality for local destruction of renal cell carcinoma. Radiofrequency applicator navigation can be performed via ultrasound, computed tomography or magnetic resonance guidance; however, ultrasound seems less favourable because of the absence of monitoring capabilities during ablation. On-line monitoring of treatment outcome can only be performed with magnetic resonance imaging giving the possibility of eventual applicator repositioning to ablate visible residual tumour tissue. Long-term follow-up is crucial to assess completeness of tumour ablation. New developments in ablation technology and radiological equipment will further increase the indication field for radiofrequency ablation of renal cell carcinoma. Altogether, radiofrequency ablation seems to be a promising new modality for the minimally invasive treatment of renal cell carcinoma, which was demonstrated to exhibit high short-term effectiveness.

    2013-05-01

    Full Text Available PURPOSE: To analyze the clinicopathological features and outcome of patients with pathologically proven superficial squamous cell carcinoma of the esophagus. METHODS: A total of 234 consecutive cases of esophageal carcinoma in a 15-year period were reviewed. RESULTS: Superficial esophageal cancer was found in five patients (2.1%. They were four men and one woman and the mean age was 52.5 years. Smoking and alcohol were the main risk factors. Achalasia due to Chagas disease occurred in one patient and a second primary tumor developed in the larynx in another patient. Four patients underwent esophagectomy and one patient received chemoradiotherapy. The histopathologic diagnosis was of squamous cell carcinoma in all cases. Intramucosal tumor (Tis was identified in three cases and superficially invasive carcinoma in two cases. Four patients are free of disease with survival times of two, four, six and nine years. The patient who developed laryngeal cancer died six years after esophagectomy. CONCLUSION: Long-term survival in patients with esophageal cancer is related to early diagnosis. Therefore, a less aggressive surgical approach, such as endoscopic resection, may be a good option for these patients, if depth of tumor invasion can be accurately predicted by the new imaging tools.

    The Gorlin-Goltz syndrome, also known as nevoid basal cell carcinoma syndrome (NBCCS), is an infrequent multisystemic disease inherited in a dominant autosomal way, which shows a high level of penetrance and variable expressiveness. It is characterized by odontogenic keratocysts in the jaw, multiple basal cell nevi carcinomas and skeletal abnormalities. This syndrome may be diagnosed early by a dentist by routine radiographic exams in the first decade of life, since the odontogenic keratocysts are usually one of the first manifestations of the syndrome. This case report presents a patient diagnosed as NBCCS by clinical, radiographic and histological findings in a 13-year-old boy. This paper highlights the importance of early diagnosis of NBCCS which can help in preventive multidisciplinary approach to provide a better prognosis for the patient.

It accounts for less than 1% of all urinary bladder carcinomas. The purpose of this study is to review the clinical features, the treatment modalities, and the overall survival of these patients. We also compare the clinical outcomes between patients of bladder small cell carcinoma (SCC and bladder urothelial carcinoma (UC. Materials and methods: We reviewed the charts of patients with bladder tumors from January 1995 to December 2012 in the Chang Gung Memorial Hospital. A total of 2421 malignant bladder tumor patients were reviewed and there were 18 patients who were diagnosed with primary bladder SCC. The patients' characteristics, including age, gender, smoking history, presented symptoms, tumor size, locations, clinical stages, treatment modalities, pathology appearance, recurrence conditions, and survival conditions were all recorded. We also compared the clinical outcomes and the overall survival rates between patients with bladder SCC and those with UC. Results: Bladder SCC accounted for about 0.74% of all bladder malignancies in our institution. The mean age at diagnosis was 70.67 years, and the male-to-female ratio was 2.6:1. Thirteen patients had a history of cigarette smoking. All patients presented with symptoms of gross hematuria, and three of them had bladder tamponade requiring blood clot evacuation by cystoscopy. Only one patient had T1 disease, ten patients had stage III disease, and seven patients had lymph node or distant metastasis (stage IV disease. The mean tumor size was 4.29 cm in diameter. For the majority (61.11% of patients, SCC coexisted with UC components. The average survival time

    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

  17. Unusual Upper Gastrointestinal Bleeding due to Late Metastasis from Renal Cell Carcinoma: A Case Report

    Directory of Open Access Journals (Sweden)

    Wen-Tsan Chang

    2004-03-01

    Full Text Available A case of recurrent massive upper gastrointestinal bleeding originating from metastatic renal cell carcinoma is reported. A 63-year-old woman underwent right nephrectomy 9 years previously and experienced no recurrence during follow-up. A gradually enlarging ulcerative tumor over the bulb of the duodenum and four subsequent episodes of massive bleeding from this tumor occurred between June 2001 and March 2002. The patient underwent surgery in April 2002 for intractable bleeding from the tumor. Renal cell carcinoma metastasis to the duodenum was confirmed from the surgical specimen. Upper gastrointestinal bleeding due to malignancy is very rare and the duodenum is the least frequently involved site. Furthermore, a solitary late renal cell carcinoma metastasis 9 years after a nephrectomy is extremely uncommon. This case suggests that life-long follow-up of renal cell carcinoma patients is necessary, owing to unpredictable behavior and the possibility of long disease-free intervals. In nephrectomized patients suffering from gastrointestinal bleeding, complete evaluation, especially endoscopic examination, is indicated. The possibility of late recurrent renal cell carcinoma metastasis to the gastrointestinal tract should be kept in mind, although it is rare. If the patient is fit for surgery, metastatectomy is the first choice of treatment.

    The prognostic value of the Fuhrman nuclear grading system has been questioned for chromophobe renal cell carcinoma (chRCC) because this subtype frequently displays nuclear and nucleolar pleomorphism. The present study reevaluates this grading system in a series of patients with nonsarcomatoid chRCC. We identified 176 patients (3.6%) with nonsarcomatoid chRCC in a total of 4897 patients who underwent surgery for renal cell carcinoma at 5 centers in Germany between 1990 and 2010. The mean follow-up was 51.1 months. The 3 groups (G1 versus G2 versus G3/4) were comparable in terms of age, sex, tumor diameter, and lymph node metastasis. They only differed significantly in tumor stage (P = .01) and the incidence of synchronous visceral metastasis (P = .04). The 5-year cancer-specific survival rates were 84.4% for G1 (n = 32), 84.3% for G2 (n = 108), and 74.1% for G3/4 tumors (n = 33) (P = .58). Accordingly, multivariate analysis including age, sex, tumor stage, and metastatic disease did not identify Fuhrman grading as an independent predictor of cancer-specific survival in patients with chRCC (P = .4). We were able to demonstrate in a large multicenter cohort that the Fuhrman grading system does not qualify as a prognostic tool in patients with chRCC. Copyright © 2014 Elsevier Inc.

    Full Text Available The most important prognostic factors for clear cell carcinoma (CCC are clinical and morphological signs and clinical stage of the disease. Analyses of 5-year survival in patients with I stage of CCC is 69 %, in II stage – 55 %, in III stage – 14 % and in IV stage – 4 % patients. We analyzed distant results of treatment of 71 patients with CCC and of 25 patients with mixed malignant ovaries neoplasm with obligatory clear cell component taking into consideration main clinical and morphological sings of disease. On the base of performed reseal we revealed that morphological structure of the tumors and stage of the disease exerted heist influence on the exponent of survival of the patients with clear CCC ovaries neoplasm. Besides, there is a correlation between exponent of patients’ survival and radicalized of surgery, character of tumor growth, differentiation degree, cell anaplasia and mitotic activity of tumor cells.

    Oral squamous cell carcinoma (OSCC) is a cancer subtype that lacks validated prognostic and therapeutic biomarkers, and human papillomavirus status has not proven beneficial in predicting patient outcomes. A gene expression pathway analysis was conducted using OSCC patient specimens to identify molecular targets that may improve management of this disease. RNA was isolated from 19 OSCCs treated surgically at the University of Alabama at Birmingham (UAB; Birmingham, AL) and evaluated using the NanoString nCounter system. Results were confirmed using the oral cavity subdivision of the Head and Neck Squamous Cell Carcinoma Cancer (HNSCC) study generated by The Cancer Genome Atlas (TCGA) Research Network. Further characterization of the in vitro phenotype produced by Notch pathway activation in HNSCC cell lines included gene expression, proliferation, cell cycle, migration, invasion, and radiosensitivity. In both UAB and TCGA samples, Notch pathway upregulation was significantly correlated with patient mortality status and with expression of the proinvasive gene FGF1 In vitro Notch activation in HNSCC cells increased transcription of FGF1 and induced a marked increase in cell migration and invasion, which was fully abrogated by FGF1 knockdown. These results reveal that increased Notch pathway signaling plays a role in cancer progression and patient outcomes in OSCC. Accordingly, the Notch-FGF interaction should be further studied as a prognostic biomarker and potential therapeutic target for OSCC. Patients with squamous cell carcinoma of the oral cavity who succumb to their disease are more likely to have upregulated Notch signaling, which may mediate a more invasive phenotype through increased FGF1 transcription.

    Full Text Available Introduction: Papillary renal-cell carcinoma, which represents around 20% of renal cell carcinomas, is a heterogeneous disease that includes different tumor types with several clinical and molecular phenotypes. Nivolumab, a fully human IgG4 programmed cell death protein 1 immune checkpoint inhibitor antibody, has shown not only an overall survival advantage when compared to everolimus, but also a relatively good side-effect profile among patients with previously treated advanced or metastatic renal-cell carcinoma. Case report: We describe a case of a young man diagnosed with papillary renal-cell carcinoma that achieved a durable response to nivolumab despite a temporary suspension of the treatment due to a renal function side effect. To our knowledge, it is the first renal failure secondary to nivolumab in a metastatic renal-cell carcinoma patient.Concluding Remarks: Nivolumab is a promising drug in patients with metastatic papillary renal-cell carcinoma and long-term responses can be achieved. In case of acute renal failure secondary to this treatment, temporary therapy suspension and a low dose of systemic corticosteroids can recover renal function without a negative impact on treatment efficacy.

    Development of esophageal squamous cell carcinoma (ESCC) involves alterations in multiple genes with corresponding proteins. Recent studies have demonstrated that centrosomal protein 55 (CEP55) shares certain features with oncogenes, and CEP55 overexpression is associated with the development and progression of malignant tumors. The present study aimed to analyze, for the first time, whether CEP55 expression is related to clinicopothalogic features in the esophageal squamous cell carcinoma (ESCC), as well as patient survival. A total of 110 patients with mid-thoracic ESCC who suffered from Ivor-Lewis were enrolled. The CEP55 expression profile of these patients in tumour tissues and corresponding healthy esophageal mucosa (CHEM) was detected by immunohistochemistry and semi-quantitative reverse transcription-polymerase chain reaction analyses. Correlations between CEP55 expression and clinicopathological factors were analyzed using χ 2 test. The log-rank test was employed to calculate survival rate. A Cox regression multivariate analysis was performed to determine independent prognostic factors. The results demonstrated that CEP55 expression in ESCC was significantly higher than that of CHEM (POverexpression of CEP55 was significantly associated with differentiation degree (P=0.022), T stage (P=0.019), lymph node metastasis (P=0.033), clinicopathological staging (P=0.002) and tumor recurrence (P=0.021) in locally advanced ESCC patients. In addition, CEP55 overexpression was significantly associated with reduced overall survival of patients after surgery (P=0.012). The 5-year survival rate of patients without CEP55 overexpression was significantly higher than that of patients with CEP55 overexpression (P=0.012). Therefore, these findings suggest that CEP55 overexpression correlates with poor prognosis in locally advanced ESCC patients.

    Hereditary leiomyomatosis and renal cell carcinoma syndrome is characterized by an increased risk of agressive renal cell carcinoma, often of type 2 papillary histology, and is caused by FH germline mutations. A prominent eosinophilic macronucleolus with a perinucleolar clear halo is distinctive of hereditary leiomyomatosis and renal cell carcinoma syndrome-associated renal cell carcinoma according to the 2012 ISUP and 2016 WHO kidney tumor classification. From an immunohistochemistry perspective, tumors are often FH-negative and S-(2-succino)-cysteine (2SC) positive. We performed a pathology review of 24 renal tumors in 23 FH mutation carriers, and compared them to 12 type 2 papillary renal cell carcinomas from FH wild-type patients. Prominent eosinophilic nucleoli with perinucleolar halos were present in almost all FH-deficient renal cell carcinomas (23/24). Unexpectedly, they were also present in 58% of type 2 papillary renal cell carcinomas from wild-type patients. Renal cell carcinoma in mutation carriers displayed a complex architecture with multiple patterns, typically papillary, tubulopapillary, and tubulocystic, but also sarcomatoid and rhabdoid. Such pattern diversity was not seen in non-carriers. FH/2SC immunohistochemistry was informative as all hereditary leiomyomatosis and renal cell carcinoma-associated renal cell carcinomas were either FH- or 2SC+. For FH and 2SC immunohistochemistries taken separately, sensitivity of negative anti-FH immunohistochemistry was 87.5% and specificity was 100%. For positive anti-2SC immunohistochemistry, sensitivity, and specificity were 91.7% and 91.7%, respectively. All FH wild-type renal cell carcinoma were FH-positive, and all but one were 2SC-negative. In conclusion, multiplicity of architectural patterns, rhabdoid/sarcomatoid components and combined FH/2SC staining, but not prominent eosinophilic nucleoli with perinucleolar halos, differentiate hereditary leiomyomatosis and renal cell carcinoma-associated renal

Meanwhile, the local inflammation, which is characterized by dense intratumoral immune infiltrate, is a favorable predictor of survival outcome. Purpose: To evaluate the role of systemic and local inflammation in predicting outcome in patients with laryngeal squamous cell carcinoma. Patients and methods: In this retrospective study, 120 patients who had undergone postoperative radiotherapy were enrolled. Neutrophil-to-lymphocyte ratio (NLR and platelet-to-lymphocyte ratio (PLR, as calculated from pretreatment whole blood counts, were used to indicate systemic inflammation. The optimal cutoff values of NLR and PLR were determined using receiver operating characteristic curve analysis. Tumor infiltrating lymphocytes (TILs density, as assessed by pathologist review of hematoxylin and eosin-stained slides, was used to represent local inflammation. Overall survival (OS and recurrence-free survival (RFS were assessed using the Kaplan–Meier method and multivariate Cox regression analysis. Results: The best cutoff was 2.79 for NLR and 112 for PLR. Kaplan–Meier analysis revealed that high NLR, high PLR, and low TILs density were significantly correlated with inferior OS and RFS, respectively (all P<0.05. The Cox proportional multivariate hazard model showed that a high pretreatment PLR and a low TILs density were both independently correlated with poor OS and RFS, respectively (all P<0.05.

    Full Text Available Matrix metalloproteinases (MMPs, a family of proteolytic enzymes produced by both stromal and tumor cells, appear to have a key role in the events leading to local invasion and metastasis by malignant neoplasms. In the present study, we evaluated the role of MMP-2, squamous cell carcinoma antigen (SCCA, and tissue polypeptide – specific antigen (TPS in cervical neoplasia. Using Western blotting and enzyme immunoassay (EIA, we analyzed 50 patients with cervical carcinoma (CC and 25 normal controls for expression of MMP-2 in tissue cell lysates. We also quantified SCCA and TPS with microparticle immunoassay and EIA, respectively. The results were correlated with human papilloma virus (HPV infection, clinicopathological findings, and disease outcome. The cutoff point for each marker was estimated from receiver operating characteristic curves. Logistic regression analysis was performed to estimate the odds ratio (OR and 95% confidence interval (CI for each marker. MMP-2, SCCA, and TPS protein expression were significantly higher in patients with CC than in normal controls. While TPS was the best marker for discriminating between patients and controls, MMP-2 was associated with an advanced tumor stage (OR, 13.9 [95% CI, 1.4-133.9] and poor histological grade (OR, 10.2 [95% CI, 1.7-60.5]. Moreover, independent of the effect of an advanced CC stage and grade, the patients' age, and the presence of HPV infection, MMP-2 was considered a strong predictor for CC recurrence (OR, 8.1 [95% CI, 1.3- 49.1]. Tissue markers may be used to select high-risk patients for early detection of and adjuvant therapy for recurrence. Our MMP-2 findings are particularly relevant to the development of protease inhibitors as a new cancer therapy approach.

    Perineural invasion resulting in leptomeningeal carcinomatosis is a rare, but well-recognized phenomenon in head and neck carcinomas. We report the rare case of a patient with a squamous cell carcinoma of the lip resulting in leptomeningeal carcinomatosis and review the relevant published work. A 51-year-old man presented with progressive facial paraesthesia after treatment for a recurrent squamous cell carcinoma of the lower lip. Cavernous sinus involvement was confirmed on MRI and he received stereotactic radiotherapy. He subsequently developed progressive lower limb neurological signs. An MRI showed multiple enhancing leptomeningeal nodules in the cervical and lumbar spine consistent with leptomeningeal carcinomatosis. Whole spine radiotherapy and dexametha-sone resulted in short-term stabilization of symptoms only and he rapidly succumbed to progressive neurological disease. To our knowledge, this is the first published report of a squamous cell carcinoma of the lip resulting in leptomeningeal disease of the cauda equina.

    Immune competence was evaluated in 43 patients of carcinoma breast, 77 patients of cancer cervix, as compared to 30 normal healthy women. The study also included 25 women from the two carcinoma groups, who had undergone radiotherapy. A reduction in the white blood cell count, absolute lymphocyte count, active T-cell count and absolute T-cell count were observed in patients with carcinoma of the breast and cervix prior to irradiation. Radiation therapy resulted in a striking reduction of all the three parameters in both the carcinoma groups. Substantial recovery was observed within a year after cessation of therapy. Increased number of peripheral B lymphocytes was observed in carcinoma of the breast as well as the cervix prior to irradiation. At completion of radiation, the number decreased markedly in both groups of patients. Gradual recovery took place within a year. The reduction in lymphocyte numbers and its subpopulations could not be attributed to thymic irradiation, since patients receiving pelvic and mediastinal (including thymic) radiotherapy showed similar changes.

    Full Text Available In advanced cancers, transforming growth factor-beta (TGFβ promotes tumor growth and metastases and suppresses host antitumor immunity. GC1008 is a human anti-TGFβ monoclonal antibody that neutralizes all isoforms of TGFβ. Here, the safety and activity of GC1008 was evaluated in patients with advanced malignant melanoma and renal cell carcinoma.In this multi-center phase I trial, cohorts of patients with previously treated malignant melanoma or renal cell carcinoma received intravenous GC1008 at 0.1, 0.3, 1, 3, 10, or 15 mg/kg on days 0, 28, 42, and 56. Patients achieving at least stable disease were eligible to receive Extended Treatment consisting of 4 doses of GC1008 every 2 weeks for up to 2 additional courses. Pharmacokinetic and exploratory biomarker assessments were performed.Twenty-nine patients, 28 with malignant melanoma and 1 with renal cell carcinoma, were enrolled and treated, 22 in the dose-escalation part and 7 in a safety cohort expansion. No dose-limiting toxicity was observed, and the maximum dose, 15 mg/kg, was determined to be safe. The development of reversible cutaneous keratoacanthomas/squamous-cell carcinomas (4 patients and hyperkeratosis was the major adverse event observed. One malignant melanoma patient achieved a partial response, and six had stable disease with a median progression-free survival of 24 weeks for these 7 patients (range, 16.4-44.4 weeks.GC1008 had no dose-limiting toxicity up to 15 mg/kg. In patients with advanced malignant melanoma and renal cell carcinoma, multiple doses of GC1008 demonstrated acceptable safety and preliminary evidence of antitumor activity, warranting further studies of single agent and combination treatments.Clinicaltrials.gov NCT00356460.

    Prolonged waiting times for radiotherapy have resulted in many centres assigning priorities to various patient or diagnostic groups. A high risk of progression on a waiting list is one factor that would reasonably influence the priority. The present descriptive study of 27 patients with Merkel cell carcinoma (MCC) found that a median wait of 24 days for radiotherapy is associated with a high risk of progression. Eleven (41%) of 27 patients developed progressive disease, including five (45%) of 11 patients waiting for adjuvant radiotherapy. Patients treated adjuvantly also had longer waiting times prior to their initial radiotherapy consultation (median 41 days), which may have contributed to the rate of progression. Merkel cell carcinoma is an aggressive but curable malignancy and appropriate management should include efforts to minimize all potential delays prior to the commencement of radiotherapy.

    Full Text Available INTRODUCTION: Oral Myiasis, a condition of infestation of the body by fly larvae (maggots is a rare pathology in humans. It is associated with poor oral hygiene, alcoholism, senility, suppurating lesions, severe halitosis. It is seen frequently in tropical countries and hot climatic regions. The reported cases in literature of oral Myiasis associated with oral cancer are few. The treatment is a mechanical removal of the maggots but a systemic treatment with Ivermectin, a semi - synthetic macrolide antibiotic, has been used successfully for treatment for oral m yiasis. We present a case of 55 yr old male alcoholic patient with oral myiasis with extensive proliferative growth of oral cavity. Our patient was managed with manual debridement and administration of systemic ivermect in along with antibiotic coverage. Incisional biopsy of the proliferative lesion showed well differentiated squamous cell carcinoma. Thus our patient showed presence of oral myiasis in association with oral squamous cell carcinoma.

    The diabetic foot ulcer is one of the major complications of diabetes mellitus leading to prolonged hospital stay. Non-healing foot ulcers in diabetes may be due to peripheral neuropathy and/or vasculopathy. Non-healing occurs following a trivial trauma due to loss of local immunity and increased infection by bacteria and fungus. Candida and mucormycosis are common fungal infection in diabetic foot ulcer. Squamous cell carcinoma in any non-healing ulcer is a common occurrence. But squamous cell carcinoma in non-healing diabetic foot ulcer is rarely reported. Here, mucormycosis in a diabetic foot ulcer which turned into squamous cell carcinoma is reported in a 62-year-old male with poor glycaemic control for last 21 years who presented with a non-healing ulcer of 8 months' duration over dorsum of left forefoot. Microbiological examination revealed presence of mucormycosis infection and histopathology of ulcer showed infiltrating well-differentiated squamous cell carcinoma. The clinicians and pathologists should be aware of these combinations because only eradication of mucormycosis may not cure the ulcer, rather presence of squamous cell carcinoma may be ignored that may be an immediate threat to the patient's life.

    Esophageal cancer is located in the 8th position of the incidence of malignant tumors and the 6th most common cause of cancer-related mortality in the world, while China has the highest incidence and mortality of esophageal cancer. Esophageal squamous cell carcinoma (ESCC), the predominant histologic type of esophageal cancer in China, accounts for about 90%. Despite recent improvement of surgical techniques and philosophy, however, the prognosis of ESCC patients treated with surgery is still poor, and 5-year survival remains unsatisfactorily low. So far, the pathogenesis of esophageal squamous cell carcinoma is still unclear, and effective prevention is also out of the question. To find the main factors affecting the prognosis of esophageal squamous cell carcinoma, and to improve the survival of patients, are the main directions of all scholars. Postoperative pathology of esophageal squamous cell carcinoma is considered to be one of the most important predictors of prognosis. Currently, the evaluation of postoperative esophageal prognosis mainly depends on TNM staging, but some criteria of its specific content and staging remains controversial. In this paper recent domestic and foreign related researches and clinical trials reports are collected, and the postoperative pathological features affecting esophageal squamous cell carcinoma prognosis were reviewed.

    Merkel cell carcinoma is a rare, very aggressive neuroectodermal tumor of the skin. It is typically located on sun-exposed skin and frequently found in white men aged between 70 and 80 years. We report a case of a 58-year-old black woman diagnosed with Merkel cell carcinoma of the posterior face of the right elbow. She had biopsy excision and was lost to follow-up. Four months later, she presented with recurrent disease on the inferior third of the right arm with three ipsilateral axillary lymph node metastases. Amputation of the right arm and ipsilateral axillary lymph node dissection were performed, followed by adjuvant radiotherapy. Six months later, the patient died as a result of respiratory failure caused by lung metastasis. To the best of our knowledge, no specific studies have been done comparing the course and the characteristics of Merkel cell carcinoma in white and black populations, and no similar case has been reported in the literature. The Merkel cell carcinoma is very rare in black people. As described elsewhere in the literature, our patient had a poor outcome despite radical management. To date, to the best of our knowledge, there has been no comparison of the prognosis of this tumor in white and black populations.

    The automated fluorometric microculture cytotoxicity assay (FMCA) is based on the measurement of fluorescence generated from cellular hydrolysis of fluorescein diacetate (FDA) to fluorescein by viable cells after a 72-hr culture period in microtiter plates. The FMCA was adopted for chemosensitivity testing of tumor cells from patients with ovarian carcinoma. Thirty-seven samples of solid tumors and malignant effusions were obtained from 35 patients at diagnosis or relapse. Tumor cells from solid samples and effusions were prepared by enzymatic digestion and centrifugation, respectively, followed by Percoll or Ficoll purification. The fluorescence was proportional to the number of cells/well and considerably higher in tumor cells than in contaminating normal cells. The effect of up to 19 cytotoxic drugs was successfully assessed in 70% of the samples and there was a good correlation between drug sensitivity data reported by the FMCA and the DiSC assay performed in parallel. The overall drug sensitivity pattern in vitro corresponded well to the clinical experience. The effect of cisplatin varied considerably between patients and resistance was found also in cases not previously exposed to cytotoxic drugs. The FMCA is a rapid and simple method that seems to report clinically relevant cytotoxic drug sensitivity data in ovarian carcinomas. In the future, this method may contribute to optimizing chemotherapy by assisting in individualized drug selection and new drug development.

    2017-09-06

    Erythrocytosis, a rare paraneoplastic syndrome, generally occurs in patients with clear cell renal cell carcinoma and has never been reported in patients with chromophobe renal cell carcinoma. We report a case of a young man suffering from a giant (22-cm) mass on his left kidney. Because of a history of polycythemia vera, the patient had been treated for the condition for 9 years. Radical nephrectomy was successfully performed, and the postoperative pathologic examination confirmed a diagnosis of chromophobe renal cell carcinoma. Unexpectedly, the symptom of erythrocytosis disappeared after the surgery. Further examination and analysis were performed, and we finally attributed his erythrocytosis to chromophobe renal cell carcinoma. Chromophobe renal cell carcinoma could cause erythrocytosis, but the clear-cut mechanism needs further research. Secondary erythrocytosis such as those related with renal tumors should be taken into consideration during the diagnosis of polycythemia vera.

    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.

  5. Resistance to Antiangiogenic Therapies by Metabolic Symbiosis in Renal Cell Carcinoma PDX Models and Patients

    Directory of Open Access Journals (Sweden)

    Gabriela Jiménez-Valerio

    2016-05-01

    Full Text Available Antiangiogenic drugs are used clinically for treatment of renal cell carcinoma (RCC as a standard first-line treatment. Nevertheless, these agents primarily serve to stabilize disease, and resistance eventually develops concomitant with progression. Here, we implicate metabolic symbiosis between tumor cells distal and proximal to remaining vessels as a mechanism of resistance to antiangiogenic therapies in patient-derived RCC orthoxenograft (PDX models and in clinical samples. This metabolic patterning is regulated by the mTOR pathway, and its inhibition effectively blocks metabolic symbiosis in PDX models. Clinically, patients treated with antiangiogenics consistently present with histologic signatures of metabolic symbiosis that are exacerbated in resistant tumors. Furthermore, the mTOR pathway is also associated in clinical samples, and its inhibition eliminates symbiotic patterning in patient samples. Overall, these data support a mechanism of resistance to antiangiogenics involving metabolic compartmentalization of tumor cells that can be inhibited by mTOR-targeted drugs.

    Cutaneous squamous cell carcinomas arise as secondary cancers in hematopoietic stem cell transplant survivors. They have been documented primarily in Western cohorts and relatively little is known about their occurrence in Asian hematopoietic stem cell transplant recipients, with no reports of squamous cell carcinomas with high-risk features in Asian patients. We describe a case of a cutaneous squamous cell carcinoma with high-risk features on the scalp of a Japanese bone marrow transplant recipient approximately 6.5 years post-transplant, who was on long-term voriconazole. The history of a photodistributed erythema followed by the appearance of multiple actinic keratoses and solar lentigines, together with the rarity of cutaneous squamous cell carcinomas in Asian hematopoietic stem cell transplant cohorts revealed in our literature review, suggest that voriconazole use contributed to the development of high-risk squamous cell carcinoma in our patient. © 2017 Japanese Dermatological Association.

    Merkel cell carcinoma, though rare, is one of the most aggressive tumors a dermatologist faces. More than a third of patients with this diagnosis die from the disease. Numerous researchers have attempted to identify clinical and pathologic predictors to guide prognosis, but their studies have produced inconsistent results. Because the incidence of Merkel cell carcinoma is low and it appears in patients of advanced age, prospective studies have not been done and no clear treatment algorithm has been developed. This review aims to provide an exhaustive, up-to-date account of Merkel cell carcinoma for the dermatologist. We describe prognostic factors and the imaging techniques that are most appropriate for evaluating disease spread. We also discuss current debates on treating Merkel cell carcinoma.

    BRCC3 has been found to be aberrantly expressed in breast tumors and involved in DNA damage response. The contribution of BRCC3 to nasopharyngeal carcinoma prognosis and radiosensitivity is still unclear. Immunohistochemical analysis of BRCC3 was carried out in 100 nasopharyngeal carcinoma tissues, and the protein level was correlated to patient survival. BRCC3 expression of nasopharyngeal carcinoma cell lines was determined by Western-blotting and real-time PCR. Additionally, the effects of BRCC3 knockdown on nasopharyngeal carcinoma cell clongenic survival, DNA damage repair, and cell cycle distribution after irradiation was assessed. The BRCC3 protein level was inversely correlated with nasopharyngeal carcinoma patient overall survival (P < 0.001) and 3-year loco-regional relapse-free survival (P = 0.034). Multivariate analysis demonstrated that BRCC3 expression was an independent prognostic factor (P = 0.010). The expression of BRCC3 was much higher in radioresistant nasopharyngeal carcinoma cells than in radiosensitive cells. Knockdown of BRCC3 increased the cell survival fraction, attenuated DNA damage repair and resulted in G2/M cell cycle arrest in radioresistant NPC cells. High BRCC3 expression in nasopharyngeal carcinoma patients is associated with poor survival. BRCC3 knockdown could abate the radioresistance in nasopharyngeal carcinoma cells. These findings suggest the utility of BRCC3 as a prognostic biomarker and novel target for nasopharyngeal carcinoma

    Full Text Available Background: Squamous and basal cell carcinomas together constitute the majority of non-melanoma skin cancers. These malignancies are infrequent in Indians as compared to the white skinned population. Literature on squamous cell carcinoma in dark skin is limited. Aim: To analyze the risk factors and to characterize the histopathological subtypes of cutaneous squamous cell carcinoma in Indian patients in an area, non-endemic for arsenicosis. Methods: A retrospective analysis of data from January 2003 to August 2013 was performed to evaluate the predisposing factors and histopathological types of cutaneous squamous cell carcinoma at the Postgraduate Institute of Medical Education and Research (PGIMER, Chandigarh. Demographic and disease characteristics such as age, gender and predisposing factors, particularly premalignant dermatoses were recorded and histopathology slides were reviewed. Results: Of the 13,426 skin biopsy specimens received during the 10-year period, there were 82 (0.6% cases of squamous cell carcinoma and 170 (1.7% of basal cell carcinoma. The mean age at diagnosis of cutaneous squamous cell carcinoma was 53.7 years and the male to female ratio was 2:1. The most common site of involvement was the lower limbs in 34 (41.5% patients. Marjolin's ulcer was present in 36 (43.9% cases. No predisposing factor was identified in 35 (42.7% patients. Histopathologically, the tumors were classified most commonly as squamous cell carcinoma not otherwise specified in 33 (40.2% cases. Limitations: This was a retrospective study and details of occupation and interval between the precursor lesions and development of tumor were not recorded. Immunohistochemistry for human papilloma virus and p53 tumor suppressor protein were not performed as these tests were not available. Conclusion: Cutaneous squamous cell carcinoma is uncommon in Indian patients and a high index of suspicion is necessary when a rapidly enlarging nodule, verrucous fungating plaque

    Upper tract transitional cell carcinomas (TCC) are uncommon and aggressive tumours. There are a number of surgical approaches to manage this condition including open radical nephroureterectomy and laparoscopic procedures. To determine the best surgical management option for upper tract transitional cell carcinoma. A sensitive search strategy was developed to identify relevant studies for inclusion in this review. The following databases were searched for randomised trials evaluating surgical approaches to the management of upper tract TCC: Medline EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL, British Nursing Index, AMED, LILACS, Web of Science®, Scopus, Biosis, TRIP, Biomed Central, Dissertation Abstracts, and ISI Proceedings. The following criteria that were considered for this review.Types of studies - All randomised or quasi-randomised controlled trials comparing the various surgical methods and approaches for the management of localised upper tract transitional cell carcinoma. Types of participants - All adult patients with localised transitional cell carcinoma. Localised disease was defined as limited to the kidney or ureter with no gross regional lymph nodal enlargement on imaging. Types of interventions - Any surgical method or approach for managing localised upper tract transitional cell carcinoma. Types of outcome measures - Overall and cancer-specific survival were primary outcomes. Surgery-related morbidity. Quality of life and health economics outcomes were secondary outcomes. Two review authors examined the search results independently to identify trials for inclusion. We identified one randomised controlled trial that met our inclusion criteria. The trial showed that the laparoscopic approach had superior peri-operative outcomes compared to open approach. Laparoscopic was superior and statistically significant for blood loss (104 mL (millilitres) versus 430 mL, P management of upper tract transitional cell carcinoma

    Full Text Available Meningeal carcinomatosis occurs in 1–18% of patients with solid tumours, most commonly carcinomas of the breast and lung or melanomas. There are relatively few reports of meningeal carcinomatosis in transitional cell carcinoma of the bladder. Isolated meningeal recurrence is particularly uncommon, and we present an unusual case of this in a 58-year-old man. The case was further complicated by the somewhat atypical presentation with a confirmed ischaemic stroke. The patient died one month after presentation.

    Approximately 100 cases of collecting duct carcinoma have been reported in the medical literature. We herein report on a case of collecting duct carcinoma of the kidney in a 75-year-old patient. The abdominal sonography depicted a relatively poorly defined 7x6 cm sized, isoechoic mass lesion, as compared to the normal parenchyma, at the left kidney lower pole and the affected kidney showed preservation of the reniform shape. CT revealed a heterogeneous poorly defined low-attenuation mass that was mainly located in the medulla with involvement of the cortex and the lower half of the renal pelvis. Retrograde ureter opyelography showed a filling defect at the lower renal pelvis and severe narrowing of the left proximal ureter. We initially thought this lesion was invasive transitional cell carcinoma. Subsequent surgery confirmed a collecting duct 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

    Full Text Available Abstract Background Trastuzumab is currently approved for the clinical treatment of breast and gastric cancer patients with HER-2 positive tumors, but not yet for the treatment of esophageal carcinoma patients, whose tumors typically show 5 ~ 35% HER-2 gene amplification and 0 ~ 56% HER-2 protein expression. This study aimed to investigate the therapeutic efficacy of Trastuzumab in patient-derived esophageal squamous cell carcinoma xenograft (PDECX mouse models. Methods PDECX models were established by implanting patient esophageal squamous cell carcinoma (ESCC tissues into immunodeficient (SCID/nude mice. HER-2 gene copy number (GCN and protein expression were determined in xenograft tissues and corresponding patient EC samples by FISH and IHC analysis. Trastuzumab anti-tumor efficacy was evaluated within these PDECX models (n = 8 animals/group. Furthermore, hotspot mutations of EGFR, K-ras, B-raf and PIK3CA genes were screened for in the PDECX models and their corresponding patient’s ESCC tissues. Similarity between the PDECX models and their corresponding patient’s ESCC tissue was confirmed by histology, morphology, HER-2 GCN and mutation. Results None of the PDECX models (or their corresponding patient’s ESCC tissues harbored HER-2 gene amplification. IHC staining showed HER-2 positivity (IHC 2+ in 2 PDECX models and negativity in 3 PDECX models. Significant tumor regression was observed in the Trastuzumab-treated EC044 HER-2 positive model (IHC 2+. A second HER-2 positive (IHC 2+ model, EC039, harbored a known PIK3CA mutation and showed strong activation of the AKT signaling pathway and was insensitive to Trastuzumab treatment, but could be resensitised using a combination of Trastuzumab and AKT inhibitor AZD5363. In summary, we established 5 PDECX mouse models and demonstrated tumor regression in response to Trastuzumab treatment in a HER-2 IHC 2+ model, but resistance in a HER-2 IHC 2+/PIK3CA mutated model.

    The aim of this study is to investigate the number of negative lymph nodes (NLNs) as a prognostic factor for survival in patients with resected esophageal squamous cell carcinoma. A total of 381 esophageal squamous cell carcinoma patients who had underwent surgical resection as the primary treatment was enrolled into this retrospective study. The impact of number of NLNs on patient's overall survival was assessed and compared with the factors among the current tumor-nodes-metastasis (TNM) staging system. The number of NLNs was closely related to the overall survival, and the 5-year survival rate was 45.4% for number of NLNs of >20 (142 cases) and 26.4% for NLNs ≤ 20 (239 cases) (P = 0.001). In multivariate survival analysis, the number of NLNs remained an independent prognostic factor (P = 0.002) as did the other current TNM factors. For subgroup analysis, the predictive value of number of NLNs was significant in patients with T3 or T4 disease (P = 0.001) and patients with N1 and N2-3 disease (P = 0.025, 0.043), but not in patients with T1 or T2 disease or patients with N0 disease. The number of NLNs, which represents the extent of lymphadenectomy for esophageal squamous cell carcinoma, could impact the overall survival of patients with resected esophageal squamous cell carcinoma, especially among those with nodal-positive disease and advanced T-stage tumor. © 2016 John Wiley & Sons Australia, Ltd.

    International guidelines for management of basal cell carcinoma are reviewed and analyzed for decision-making in the appropriate therapeutic behavior for patients. The different therapies for the treatment of basal cell carcinoma are described. Different therapies are evaluated according to the risk (low or high) of recurrence to determine the appropriate treatment. According to the evidence, low-risk tumors have responded to topical therapy, curettage and electrodesiccation, cryotherapy or simple resection, and high-risk tumors are managed with surgery, radiotherapy or Mohs' micrographic surgery [es

    To identify candidate microRNAs (miRNAs) in the serum of patients with clear cell carcinomas in monitoring disease progression. The sera of patients with diagnosed ovarian clear cell carcinoma were collected from 2009 to 2012. Real-time quantitative polymerase chain reaction (PCR) analysis for 270 miRNAs was performed. To offset the potential extraction bias, an equal amount of Caenorhabditis elegans cel-miR-238 was added to each serum specimen before miRNA isolation. miRNA expression was analyzed using the ΔCt method, with cel-miR-238 as controls. Twenty-one patients with clear cell carcinoma were included. In the discovery phase on four pairs of pre- and postoperative sera, 18 differentially expressed miRNAs were selected from 270 miRNAs. In the validation phase on an independent set of 11 pairs of pre- and postoperative sera, 4 miRNAs (hsa-miR-130a, hsa-miR-138, hsa-miR-187, and hsa-miR-202) were confirmed to be higher in the preoperative sera. In the application phase, hsa-miR-130a remained consistent with the different time points in seven of the 10 patients during clinical follow-up periods. More importantly, in three patients, hsa-miR-130a levels were elevated in early disease recurrences before CA125 was found to be elevated. Hsa-miR-130a may be a useful serum biomarker for detecting recurrence of ovarian clear cell cancer, and warrants further studies. Copyright © 2014. Published by Elsevier B.V.

    Full Text Available Abstract Background Mucosal squamous cell carcinoma of the head and neck is a disease of high mortality and morbidity. Interactions between the squamous cell carcinoma and the host's local immunity, and how the latter contributes to the biological behavior of the tumor are unclear. In vivo studies have demonstrated sequential mast cell infiltration and degranulation during squamous cell carcinogenesis. The degree of mast cell activation correlates closely with distinct phases of hyperkeratosis, dysplasia, carcinoma in-situ and invasive carcinoma. However, the role of mast cells in carcinogenesis is unclear. Aim This study explores the effects of mast cells on the proliferation and gene expression profile of mucosal squamous cell carcinoma using human mast cell line (HMC-1 and human glossal squamous cell carcinoma cell line (SCC25. Methods HMC-1 and SCC25 were co-cultured in a two-compartment chamber, separated by a polycarbonate membrane. HMC-1 was stimulated to degranulate with calcium ionophore A23187. The experiments were done in quadruplicate. Negative controls were established where SCC25 were cultured alone without HMC-1. At 12, 24, 48 and 72 hours, proliferation and viability of SCC25 were assessed with MTT colorimetric assay. cDNA microarray was employed to study differential gene expression between co-cultured and control SCC25. Results HMC-1/SCC25 co-culture resulted in suppression of growth rate for SCC-25 (34% compared with 110% for the control by 72 hours, p Conclusion We show that mast cells have a direct inhibitory effect on the proliferation of mucosal squamous cell carcinoma in vitro by dysregulating key genes in apoptosis and cell cycle control.

    The diagnostic role of cyclooxygenase-2 (COX-2) expression in laryngeal atypical hyperplasia, vocal fold nodule, and laryngeal squamous cell carcinoma was examined. Specimens obtained from patients diagnosed with vocal fold nodule (n = 35), atypical hyperplasia (n = 35), laryngeal squamous cell carcinoma (n = 35), and clinical parameters were evaluated retrospectively. Although no staining was observed in patients with vocal fold nodules, staining was noted in laryngeal atypical hyperplasia and squamous cell carcinoma. The percentage of COX-2 staining was the highest in the carcinoma group. It was determined that COX-2 staining was significantly associated with laryngeal squamous cell carcinoma. It should be noted that overexpression of COX-2, a potentially important factor in the evolution of carcinogenesis in precancerous lesions, might be an indicator of the development of carcinoma.

    Full Text Available We report a 44-year-old man with primary gastric small cell carcinoma who showed a remarkable response to chemotherapy specific for pulmonary small cell carcinoma. The patient had been admitted to another local hospital because of intermittent epigastralgia. An upper gastrointestinal examination there revealed an ulcerative tumor, 5 cm in diameter, on the lesser curvature side of the cardia, and endoscopic biopsy reported adenocarcinoma. Computed tomography revealed a mass over the lesser curvature of the stomach and some enlarged regional lymph nodes. Radical total gastrectomy, lymph node dissection, Roux-en-Y esophagojejunostomy and splenectomy were performed at our hospital. Pathology revealed gastric mucosa infiltrated by small-sized tumor cells with scanty cytoplasm and hyperchromatic nuclei. Immunohisto- chemically, the tumor cells were positive for synaptophysin, chromogranin A, and CD56. Primary gastric small cell carcinoma was diagnosed. The postoperative course, complicated by shock due to bleeding, wound infection and intra-abdominal abscess, took more than 2 months to resolve. Follow-up computed tomography showed tumor recurrence with multiple enlarged lymph nodes in the aortocaval region and hepatic hilum. The patient received palliative chemotherapy consisting of cisplatin 80 mg/m2 on day 1 and etoposide 80 mg/m2 on days 1–3 every 28 days, and had partial response to the chemotherapy, with a progression-free survival of 10 months. Chemotherapy with cisplatin and etoposide used for small cell carcinoma of the lung is a good treatment for gastric small cell carcinoma.

    Renal cell carcinoma is a common neoplasia of the adult kidney that accounts for about 3% of adult malignancies. Clear cell renal carcinoma is the most frequent subtype of kidney cancer and 20–40% of patients develop metastases. The absence of appropriate biomarkers complicates diagnosis and prognosis of this disease. In this regard, small noncoding RNAs (microRNAs), which are mutated in several neoplastic diseases including kidney carcinoma, may be optimal candidates as biomarkers for diagnosis and prognosis of this kind of cancer. Here we show that patients with clear cell kidney carcinoma that express low levels of miR501-5p exhibited a good prognosis compared with patients with unchanged or high levels of this microRNA. Consistently, in kidney carcinoma cells the downregulation of miR501-5p induced an increased caspase-3 activity, p53 expression as well as decreased mTOR activation, leading to stimulation of the apoptotic pathway. Conversely, miR501-5p upregulation enhanced the activity of mTOR and promoted both cell proliferation and survival. These biological processes occurred through p53 inactivation by proteasome degradation in a mechanism involving MDM2-mediated p53 ubiquitination. Our results support a role for miR501-5p in balancing apoptosis and cell survival in clear cell renal carcinoma. In particular, the downregulation of microRNA501-5p promotes a good prognosis, while its upregulation contributes to a poor prognosis, in particular, if associated with p53 and MDM2 overexpression and mTOR activation. Thus, the expression of miR501-5p is a possible biomarker for the prognosis of clear cell renal carcinoma. PMID:25426415

    To investigate the role of neutrophil-to-lymphocyte ratio as a prognostic indicator in patients with localized clear cell renal cell carcinoma treated with radiofrequency ablation. We retrospectively analyzed data from patients with renal cell carcinoma who underwent radiofrequency ablation from 2006 to 2013. The Kaplan-Meier method was used to generate the survival curves according to different categories of neutrophil-to-lymphocyte ratio. Relationships between preoperative neutrophil-to-lymphocyte ratio or the change of neutrophil-to-lymphocyte ratio and survival were evaluated with multivariable Cox proportional hazards regression analysis. A propensity score matching analysis was carried out to avoid confounding bias. A total of 185 patients were included in present study. When stratified by preoperative neutrophil-to-lymphocyte ratio cutoff value of 2.79, 5-year recurrence-free survival, 5-year disease-free survival, and 5-year overall survival rates of neutrophil-to-lymphocyte ratio analysis, 5-year recurrence-free survival, 5-year disease-free survival, and 5-year overall survival rates of neutrophil-to-lymphocyte ratio ratio with the change of neutrophil-to-lymphocyte ratio, patients with both preoperative neutrophil-to-lymphocyte ratio ≥2.79 and the change of neutrophil-to-lymphocyte ratio ≥0.40 had the worst disease-free survival. Results of multivariable analysis showed that preoperative neutrophil-to-lymphocyte ratio and the change of neutrophil-to-lymphocyte ratio correlated with cancer relapse remarkably. High preoperative neutrophil-to-lymphocyte ratio and elevated postoperative neutrophil-to-lymphocyte ratio are associated with significant increase in risk of local recurrence as well as distant metastasis. The combination of neutrophil-to-lymphocyte ratio with the other prognostic indicators can be applied in the evaluation of relapse risk in patients with clear cell renal cell carcinoma after radiofrequency ablation.

    Squamous cell carcinoma arising in an odontogenic cyst is uncommon. The diagnosis of carcinoma arising in a cyst requires that there must be an area of microscopic transition from the benign epithelial cyst lining to the invasive squamous cell carcinoma. We report a histopathologically proven case of squamous cell carcinoma arising in a residual mandibular cyst in a 54-year-old woman.

This breakthrough in science led to the development of a variety of small molecules inhibiting the VEGF-dependent angiogenic pathway, such as sunitinib and sorafenib. These agents prolong overall and progression-free survival, respectively. The result was the development of robust front-line therapies which ultimately fail and are associated with disease progression. In this setting, there existed an unmet need for developing second-line therapies for patients with refractory metastatic renal cell carcinoma (MRCC. Everolimus (RAD 001 is an oral inhibitor of the mammalian target of rapamycin (mTOR pathway. The double-blind, randomized, placebo-controlled phase III trial of everolimus (RECORD-1 conducted in MRCC patients after progression on sunitinib or sorafenib, or both, demonstrated a progression-free survival benefit favoring the study drug (4.9 months vs 1.9 months, HR 0.33, 95% CI 0.25 to 0.43, P ≤ 0 0.001. Everolimus thus established itself as a standard of care in the second-line setting for patients with MRCC who have failed treatment with VEGF receptor inhibitors.Keywords: mTOR inhibitor, mammalian target of rapamycin inhibitor, signal transduction inhibitor, renal cell carcinoma, targeted therapy

  10. The importance of superficial basal cell carcinoma in a retrospective study of 139 patients who underwent Mohs micrographic surgery in a Brazilian university hospital

    Full Text Available OBJECTIVE: Mohs micrographic surgery is a specialized surgical procedure used to treat skin cancer. The purpose of this study was to better understand the profile of the patients who underwent the procedure and to determine how histology might be related to complications and the number of stages required for complete removal. METHODS: The records of patients who underwent Mohs micrographic surgery from October 2008 to November 2013 at the Dermatology Division of the Hospital of the Campinas University were assessed. The variables included were gender, age, anatomical location, histology, number of stages required and complications. RESULTS: Contingency tables were used to compare the number of stages with the histological diagnosis. The analysis showed that patients with superficial basal cell carcinoma were 9.03 times more likely to require more than one stage. A comparison between complications and histological diagnosis showed that patients with superficial basal cell carcinoma were 6.5 times more likely to experience complications. CONCLUSION: Although superficial basal cell carcinoma is typically thought to represent a less-aggressive variant of these tumors, its propensity for demonstrating “skip areas” and clinically indistinct borders make it a challenge to treat. Its particular nature may result in the higher number of surgery stages required, which may, as a consequence, result in more complications, including recurrence. Recurrence likely occurs due to the inadequate excision of the tumors despite their clear margins. Further research on this subtype of basal cell carcinoma is needed to optimize treatments and decrease morbidity.

    In developed countries, there has been increased incidental detection of renal cell carcinoma (RCC). The incidence, pathological stage and survival of incidentally detected carcinoma in a developing country in Asia where, from 1990 to 1998, 165 renal cell carcinomas were identified. The clinical presentation, diagnostic-imaging modality employed, pathological staging and patient survival was reviewed. Incidental renal cancers included those that were diagnosed through health screening or detected incidentally through imaging studies for other conditions. The survival between these incidentally detected lesions and their symptomatic counterparts (suspected group) was compared. Sixty-four patients (39%) had their tumours detected incidentally, including 39 who were entirely asymptomatic and 25 who presented with non-specific symptoms, not initially suggestive of RCC. For the entire group, computed tomography provided the definitive diagnosis in 81% of cases. The incidental detection group had significantly smaller size of tumour (5.9 cm c.f. 7.6 cm), lower stage and lower histological grading. In particular, 78% of patients with incidental RCC had stage I or II diseases (TNM stage classification), compared with 57% of patients with suspected tumour (p c.f. 66% at last follow up; p < 0.05; log-rank test) over a mean follow up period of 33 months (range 1-91). Regression analysis showed that stage of disease was the only independent variable predictive of clinical outcome. In conclusion, that significant numbers of RCC were detected incidentally. These tumours were of a lower clinical pathological stage and had a better prognosis.

    Objective: To evaluate treatment results and prognostic factors of 47 patients with primary urethral transitional cell carcinoma treated with post-operative adjuvant radiotherapy. Methods: From October 1998 to October 2008, 47 patients with primary urethral transitional cell carcinoma received postoperative adjuvant radiotherapy. Thirty-one patients had stage T 3 /T 4 disease, 7 had lymph node metastasis. Thirty-nine patients had G3 tumor, 13 had stump-positive. The median radiotherapy dose was 60 Gy (36-64 Gy). 81% patients (38/47) were treated with regional irradiation. Results: The median follow-up time was 21 months (6 -88 months). The follow-up rate was 92%. The median overall survival time was 35 months (5 -88 months). The 2-and 5-year overall survival rates were 57% and 49%, respectively. In univariate analysis, the median overall survival time was better in patients with stage T 1 or T 2 compared with stage T 3 or T 4 tumor (42 months vs. 19 months, χ 2 =7.28, P=0.007), with age of ≤65 years compared with >65 years (28 mouths vs 18 months,χ 2 =8.23, P =0.004). There was no significant difference in the long term survival in patients with non-radical surgery compared with radical mastectomy (21 months vs. 20 months, χ 2 = 0.90, P = 0.344). In multivariate analysis, the stage T 3 or T 4 (χ 2 = 7.89, P =0.005), >65 years old (χ 2 = 4.85, P = 0.028), renal pelvis involvement (χ 2 = 5.65, P = 0.018), and tumor located in the mid or inferior segment (χ 2 =6.08,P =0.014) were factors associated with poorer prognosis. Conclusions: Postoperative adjuvant radiotherapy can improve the efficacy of patients with locally advanced urethral transitional cell carcinoma. Advanced T stage and > 65 years age are associated with poorer prognosis. (authors)

    To identify those with a micropapillary pattern, ascertain relative frequency and document clinicopathological characteristics by reviewing gastric carcinomas. One hundred and fifty-one patients diagnosed with gastric cancer who underwent gastrectomy were retrospectively studied and the presence of a regional invasive micropapillary component was evaluated by light microscopy. All available hematoxylin-eosin (HE)-stained slides were histologically reviewed and 5 tumors were selected as putative micropapillary carcinoma when cancer cell clusters without a vascular core within empty lymphatic-like space comprised at least 5% of the tumor. Tumor tissues from these 5 invasive gastric carcinomas were immunostained using an anti-mucin 1 (MUC1) antibody (clone MA695) to detect the characteristic inside-out pattern and with D2-40 antibody to determine the presence of intratumoral lymph vessels. Detection of intraepithelial neutrophil apoptosis was evaluated in consecutive histological tissue sections by three independent methods, namely light microscopy with HE staining, the conventional terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end-labeling (TUNEL) method and immunohistochemistry for activated caspase-3 (clone C92-605). Among 151 gastric cancers resected for cure, 5 (3.3%) were adenocarcinomas with a micropapillary component. Four of the patients died of disease from 6 to 23 mo and one patient was alive with metastases at 9 mo. All patients had advanced-stage cancer (≥ pT2) and lymph node metastasis. Positive MUC1 immunostaining on the stroma-facing surface (inside-out pattern) of the carcinomatous cluster cells, together with negative immunostaining for D2-40 in the cells limiting lymphatic-like spaces, confirmed the true micropapillary pattern in these gastric neoplasms. In all five cases, several micropapillae were infiltrated by neutrophils. HE staining, TUNEL assay and immunostaining for caspase-3 demonstrated apoptotic neutrophils within

    Full Text Available Tumor formation is a complex process that occurs in different steps and involves many cell types, including tumor cells, endothelial cells, and inflammatory cells, which interact to promote growth of the tumor mass and metastasization. Epigenetic alterations occurring in transformed cells result in de-regulation of miRNA expression (a class of small non-coding RNA that regulates multiple functions which contributes to tumorigenesis. The specific miRNAs, which have an aberrant expression in tumors, are defined as oncomiRNAs, and may be either over- or under-expressed, but down-regulation is most commonly observed.Renal cell carcinoma is a frequent form of urologic tumor, associated with an alteration of multiple signaling pathways. Many molecules involved in the progression of renal cell carcinomas, such as HIF, VEGF or mTOR, are possible targets of deregulated miRNAs. Within tumor mass, the cancer stem cell population is a fundamental component that promotes tumor growth. The cancer stem cell hypothesis postulates that cancer stem cells have the unique ability to self-renew and to maintain tumor growth and metastasis. Cancer stem cells present in renal cell carcinoma were shown to express the mesenchymal stem cell marker CD105 and to exhibit self-renewal and clonogenic properties, as well as the ability to generate serially transplantable tumors. The phenotype of cancer stem cell has been related to the potential to undergo the epithelial-mesenchymal transition, which has been linked to the expression pattern of tumorigenic miRNAs or down-regulation of anti-tumor miRNAs. In addition, the pattern of circulating miRNAs may allow discrimination between healthy and tumor patients. Therefore, a miRNA signature may be used as a tumor biomarker for cancer diagnosis, as well as to classify the risk of relapse and metastasis, and for a guide for therapy.

    Full Text Available Background: Neo-angiogenesis is an essential process in physiological and pathological conditions. However, it is a complex process. Several studies demonstrated that intra-tumoural microvessel number is a significant predictor of metastasis and clinical outcome in many tumours, including oral malignancies. The immuno-surveillance cells, mast cells and eosinophils are implicated in the biological behaviour of tumours. Nevertheless, their function in tissues is uncertain. Mast cells are involved in homeostatic regulation of blood vessels as well as host defence. In some malignancies, high mast cell density has been found to correlate with favourable prognosis. However, others reported unfavourable associations. Tumour associated tissue eosinophilia is a well-known phenomena. It has been associated with good and poor prognosis. However, the role of eosinophils in tumours remains controversial. Therefore, this study was designed to investigate the prognostic value of microvessel, mast cell and eosinophil densities in the context of clinico-pathological parameters and survival in squamous cell carcinoma of the tongue.Materials and Methods: Anti-CD105 and anti-tryptase monoclonal antibodies were utilized to highlight and count microvessels and mast cells respectively in 81 cases of tongue squamous cell carcinoma. Eosinophils were demonstrated using carbol chromotrope histochemical stain. The densities were counted per mm2 and correlated with patients’ outcome and other clinico-pathological parameters using non-parametric tests and student’s t-test. Clinically, the cases were divided into 4 main groups depending on survival time, lymph-node or distant metastasis.Results: The 5 year survival was significantly lower in patients with a low mast cell density than those with a high density (p=0.006, Kruskal-Wallis test. The survival group-A demonstrated significantly higher mast cell and microvessel numbers than group-D (p=0.007, student’s t

    Objectives To assess the recent prognostic trends in oesophageal adenocarcinoma and oesophageal squamous cell carcinoma undergoing resectional surgery and no such surgery. Additionally, risk factors for death were assessed in each of these patient groups. Design Cohort study. Setting A population-based, nationwide study in Sweden. Participants All patients diagnosed with oesophageal adenocarcinoma and oesophageal squamous cell carcinoma in Sweden from 1 January 1990 to 31 December 2013, with follow-up until 14 May 2017. Outcome measures Observed and relative (to the background population) 1-year, 3-year and 5-year survivals were analysed using life table method. Multivariable Cox regression provided HR with 95% CI for risk factors of death. Results Among 3794 patients with oesophageal adenocarcinoma and 4631 with oesophageal squamous cell carcinoma, 82% and 63% were men, respectively. From 1990–1994 to 2010–2013, the relative 5-year survival increased from 12% to 15% for oesophageal adenocarcinoma and from 9% to 12% for oesophageal squamous cell carcinoma. The corresponding survival following surgery increased from 27% to 45% in oesophageal adenocarcinoma and from 24% to 43% in oesophageal squamous cell carcinoma. In patients not undergoing surgery, the survival increased from 3% to 4% for oesophageal adenocarcinoma and from 3% to 6% for oesophageal squamous cell carcinoma. Women with oesophageal squamous cell carcinoma had better prognosis than men both following surgery (HR 0.71, 95% CI 0.61 to 0.83) and no surgery (HR 0.86, 95% CI 0.81 to 0.93). Conclusions The prognosis has improved over calendar time both in oesophageal adenocarcinoma and oesophageal squamous cell carcinoma in Sweden that did and did not undergo surgery. Women appear to have better prognosis in oesophageal squamous cell carcinoma than men, independent of treatment. PMID:29748347

    Head and neck squamous cell carcinoma (HNSCC) is typically diagnosed at advanced stages with evident loco-regional and/or distal metastases. The prevalence of metastatic lesions directly correlates with poor patient outcome, resulting in high patient mortality rates following metastatic development. The progression to metastatic disease requires changes not only in the carcinoma cells, but also in the surrounding stromal cells and tumor microenvironment. Within the microenvironment, acellular contributions from the surrounding extracellular matrix, along with contributions from various infiltrating immune cells, tumor associated fibroblasts, and endothelial cells facilitate the spread of tumor cells from the primary site to the rest of the body. Thus far, most attempts to limit metastatic spread through therapeutic intervention have failed to show patient benefit in clinic trails. The goal of this review is highlight the complexity of invasion-promoting interactions in the HNSCC tumor microenvironment, focusing on contributions from tumor and stromal cells in order to assist future therapeutic development and patient treatment.

    Prediction models for outcome of decompressive surgical resection of spinal epidural metastases (SEM) have in common that they have been developed for all types of SEM, irrespective of the type of primary tumor. It is our experience in clinical practice, however, that these models often fail to accurately predict outcome in the individual patient. To investigate whether decision making could be optimized by applying tumor-specific prediction models. For the proof of concept, we analyzed patients with SEM from renal cell carcinoma that we have operated on. Retrospective chart analysis 2006 to 2012. Twenty-one consecutive patients with symptomatic SEM of renal cell carcinoma. Predictive factors for survival. Next to established predictive factors for survival, we analyzed the predictive value of the Motzer criteria in these patients. The Motzer criteria comprise a specific and validated risk model for survival in patients with renal cell carcinoma. After multivariable analysis, only Motzer intermediate (hazard ratio [HR] 17.4, 95% confidence interval [CI] 1.82-166, p=.01) and high risk (HR 39.3, 95% CI 3.10-499, p=.005) turned out to be significantly associated with survival in patients with renal cell carcinoma that we have operated on. In this study, we have demonstrated that decision making could have been optimized by implementing the Motzer criteria next to established prediction models. We, therefore, suggest that in future, in patients with SEM from renal cell carcinoma, the Motzer criteria are also taken into account. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Skin fibroblasts and tumor fibroblasts were extracted from a 64-year old male patient clinically diagnosed with laryngeal carcinoma. Control and tumor specific induced pluripotent stem cells were reprogrammed with 5 reprogramming factors, Klf-4, c-Myc, Oct-4, Sox-2, and Lin-28, using the messenger RNA reprogramming system. The transgene-free iPSC lines showed pluripotency, confirmed by immunofluorescence staining. The iPSC lines also showed normal karyotype, and could form embryoid bodies in vitro and differentiate into the 3 germ layers in vivo. This in vitro cellular model can be used to study the oncogenesis and pathogenesis of laryngeal carcinoma.

    Full Text Available Hepatocellular carcinoma (HCC shows many pathological features, and it varies architecturally and cytologically. There have been many reports and discussions of the morphological features of HCC. A 63-year-old man was found to have a solitary tumor in liver segment 7 that was diagnosed as HCC. A partial resection of liver segment 7 was performed. Microscopically, the tumor lesion showed a moderately differentiated HCC. There was also a lesion with foamy histiocyte-like cells corresponding to the white lesion in the face of the cut tumor. Immunohistochemical staining showed that they were negative for CD68, S-100, vimentin, and HMB-45. The cytoplasm itself was negative on periodic acid Schiff (PAS and Sudan staining. Without immunohistological analysis, it is difficult to distinguish this HCC variant from clear cell carcinoma or metastases of renal cell carcinoma. It is important to recognize this type as a specific cytological variant of HCC that requires confirmation by immunohistochemistry. This report describes the case of a patient with a morphologically distinctive pattern of HCC with prominent cell cytoplasm that had a foamy histiocyte-like appearance. To the best of our knowledge, this is the first report of this HCC variant.

    Extracellular matrix metalloproteinase inducer (EMMPRIN) has been reported to play crucial roles, including in angiogenesis, in several carcinomas. However, the correlation between EMMPRIN levels and angiogenesis expression profile has not been reported, and the role of EMMPRIN in renal cell carcinoma (RCC) is unclear. In the present study, we evaluated the association of EMMPRIN with angiogenesis, its value in prognosis, and its roles in RCC. EMMPRIN expression was examined in 50 RCC patients treated with radical nephrectomy. Angiogenesis, proliferation, and invasion activity were evaluated using EMMPRIN knockdown RCC cell lines. The size of EMMPRIN-overexpressing xenografts was measured and the degree of angiogenesis was quantified. EMMPRIN expression was evaluated in RCC patients who received sunitinib therapy and in sunitinib-resistant cells. Further, the relation between EMMPRIN expression and sensitivity to sunitinib was examined. EMMPRIN score was significantly associated with clinicopathological parameters in RCC patients, as well as being significantly correlated with microvessel area (MVA) in immature vessels and with prognosis. Down-regulation of EMMPRIN by siRNA led to decreased VEGF and bFGF expression, cell proliferation, and invasive potential. EMMPRIN over-expressing xenografts showed accelerated growth and MVA of immature vessels. EMMPRIN expression was significantly increased in patients who received sunitinib therapy as well as in sunitinib-resistant 786-O cells (786-suni). EMMPRIN-overexpressing RCC cells were resistant to sunitinib. Our findings indicate that high expression of EMMPRIN in RCC plays important roles in tumor progression and sunitinib resistance. Therefore, EMMPRIN could be a novel target for the treatment of RCC.

    Primary candidiasis is rare and often confused with a pre-cancerous lesion, squamous cell carcinoma, or verrucous carcinoma. We report an extremely rare case of squamous cell carcinoma of the vocal cord following primary candidiasis. A 62-year-old man presented to our department reporting a 1-month history of hoarseness. He underwent laryngeal microscopic surgery for a presumptive diagnosis of glottic carcinoma. Histopathologic examination revealed candidiasis and scattered moderate dysplasia. He was treated with itraconazole for 4 weeks, and followed up without any recurrence of candidiasis. However, the 42-month follow-up examination revealed a focal whitish lesion on the right true vocal cord, and a repeat biopsy of this area revealed squamous cell carcinoma without evidence of candidiasis. The patient was treated with radiotherapy and remains well with no signs of tumor recurrence or candidiasis.

    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.

    Full Text Available The small intestine is a very uncommon and peculiar site for metastasis from renal cell carcinoma (RCC. We present a clinical presentation of insidious and unusual development of a jejunal metastasis while having stable disease in a remainder of metastatic sites, in a patient undergoing immunotherapy with nivolumab. Due to the extreme rarity of metastatic renal cell carcinoma to the lumen of the small bowel, it is easy to overlook and misdiagnose symptoms of this pathologic entity, particularly when the remainder of metastatic disease responds well to ongoing therapy.

    Purpose: Papillary carcinoma is the most frequent type of thyroid cancer and was considered the most benign of all thyroid carcinomas, with a low risk of distant metastases. However, there are some variants of papillary thyroid carcinoma that have affinity to spread in many organs, such as: lymph nodes, lungs and bones. Aim: The aim of this study was presentation of a case with papillary carcinoma of the thyroid gland, very persistent and resistant in treatment with I 131. Material and results: A man 56 years old were diagnosed with papillary carcinoma of thyroid gland. He underwent a surgical removal of the tumor and right lobe of thyroid gland. With histopathology examination, were confirmed follicular variant of papillary carcinoma pT4. Two weeks later he underwent total thyroidectomy and was treated with 100 mCi of J 131. Six months later, the value of thyroglobulin was found elevated above upper measured limits (more than 500 ng/ml). Patient underwent surgical removal of 10 metastatic lymph nodes in the left side of the neck and has been treated with 145 mCi of radioiodine I 131. The examination after 5 months shows elevation of thyroglobulin, more than 20000 ng/ml and focally uptake of J 131 in the left lung. Patient was treated once again with 150 mCi radioiodine J 131. Whole body scintigraphy was registered focal uptake of radioiodine in the middle of the left collarbone. After a month, patient refers the enlargement of the lymph node in the right side of the neck. Currently patient is being treated with kinase inhibitor drug sorafenib and ibandronate. We have identified first positive response in treatment. Enlarged lymph node in the neck was reduced and the patient began feeling better. Conclusion: This study suggests that some subtypes of papillary thyroid carcinoma appear to have more aggressive biological course. Subtypes of papillary thyroid carcinoma such as diffuse sclerosing carcinoma, tall cell or columnar cell and insular variants, appears to

    Full Text Available Renal cell carcinoma is known to cause metastasis to unusual sites, which can be both synchronous or metachronous. Thyroid gland is a rare site for metastasis, but when it occurs, renal cell carcinoma is the most common primary neoplasm. We report the case of a 81-year-old female patient who had a significant medical history of right clear cell renal carcinoma with adrenal metastasis. She underwent right radical nephrectomy and adrenalectomy followed by radiofrequency ablation of left adrenal metastasis and systemic chemotherapy with sunitinib. Eleven years later, she presented with dysphagia and was found to have distal esophageal adenocarcinoma. On imaging, there was incidental detection of a left renal mass lesion and a right thyroid nodule, which on histopathology and immunohistochemistry were confirmed to be clear cell carcinoma of renal origin.

    Background. The HER-2 protein or p185her2 is a membrane receptor with tyrosine kinase activity encoded by HER-2/neu gene. Overexpression of HER-2/neu has been observed in many human cancers, including lung cancer. In the study, the expression of HER-2 protein is determined in the spectrum of lung cancer (adenocarcinoma, squamous cell carcinoma and small cell carcinoma). Patients and methods. The study population consisted of two groups: 19 patients that had undergone surgical treatment and 10 patients that had undergone fiber-optic bronchoscopy and biopsy for primary diagnosis only. Tissue specimens were neutral formaldehyde-fixed and paraffin-embedded. Standard histochemical and immunohistochemical staining were used for diagnosis. Expression of HER-2/neu protein was determined by immunohistochemical staining with Hercep Test (DAKO). The results were graded 0-1 as negative and 2-3 as positive. Results. Overall incidence of HER-2/neu overexpression was 34.4% (10 of 29). Higher incidence was found in the patients with adenocarcinoma 45.4% (5 of 11). In squamous cell carcinoma and small cell carcinoma, the overexpression incidence was 30.7% (4 of 13) and 20% (1 of 5), respectively. No statistically significant difference was seen given the age and gender. HER-2/neu overexpression was more pronounced in the patients with advanced tumour: all patients with squamous cell carcinoma and HER-2/neu overexpression had stage IIIB and stage IV disease, while 80 % of adenocarcinoma patients with HER-2/neu overexpression had stage IIIA and IIIB disease. Conclusions. These results are satisfactory and encourage us to continue this work in the follow-up study to evaluate HER-2/neu role as predictive and prognostic factor for the patients with lung cancer.

    Sunitinib is a standard first-line option for metastatic renal cell carcinoma (mRCC). Body composition is a prognostic factor in cancer patients and patients with loss of skeletal muscle mass and fat-free mass (FFM) are prone to dose-limiting toxicity (DLT) during targeted drug therapy. We investigated whether body composition by computed tomography predicted DLT from sunitinib in mRCC.

    The objective of this study was to clarify the magnetic resonance imaging (MRI) findings of large chromophobe renal cell carcinomas. Five patients diagnosed pathologically with chromophobe renal cell carcinoma are included. MRI findings were retrospectively evaluated for the tumor contour, uniformity and hypointensity of the rim of the tumor on T2-weighted images, ''micro-scopic fat'', enhancement degree and pattern on dynamic study, and necrosis in the tumor, among other findings. The tumor size ranged from 4.8 to 13.7 cm (mean 7.9 cm). The tumor contour was well defined in four patients. All but one tumor showed a hypointensity rim, and all tumors had a heterogeneous appearance on T2-weighted images. ''Microscopic fat'' was detected in one case. All tumors demonstrated low enhancement compared to that of the renal cortex. All tumors showed heterogeneous enhancement on postcontrast images. Necrosis was seen in four. Hemorrhage and renal vein thrombosis was seen in one. Chromophobe renal cell carcinomas of large size tend to have a heterogeneous appearance on post-contrast and T2-weighted images, a well-defined tumor contour with a hypointensity rim on T2-wighted images, and lower enhancement than that of the renal cortex. Tumor necrosis is easily apparent, and ''microscopic fat'' may be observed. (author)

    Cheng, Shaun Kian Hong; Chuah, Khoon Leong

    2016-06-01

    The pancreas is an unusual site for tumor metastasis, accounting for only 2% to 5% of all malignancies affecting the pancreas. The more common metastases affecting the pancreas include renal cell carcinomas, melanomas, colorectal carcinomas, breast carcinomas, and sarcomas. Although pancreatic involvement by nonrenal malignancies indicates widespread systemic disease, metastatic renal cell carcinoma to the pancreas often represents an isolated event and is thus amenable to surgical resection, which is associated with long-term survival. As such, it is important to accurately diagnose pancreatic involvement by metastatic renal cell carcinoma on histology, especially given that renal cell carcinoma metastasis may manifest more than a decade after its initial presentation and diagnosis. In this review, we discuss the clinicopathologic findings of isolated renal cell carcinoma metastases of the pancreas, with special emphasis on separating metastatic renal cell carcinoma and its various differential diagnoses in the pancreas.

    In the current study the presence of extracellular IL-1B, IL-8, OAZ and SAT mRNAs in the saliva was evaluated as a tool in the early detection of oral squamous cell carcinoma. 34 patients with primary oral squamous cell carcinoma stage T1N0M0/T2N0M0, 20 patients with oral leukoplakia and dysplasia (15 patients with mild dysplasia and 5 with severe dysplasia/in situ carcinoma) and 31 matched healthy-control subjects were included in the study. The presence of IL-1B, IL-8, OAZ and SAT mRNA was evaluated in extracellular RNA isolated from saliva samples using sequence-specific primers and real-time RT-PCR. ROC curve analysis was used to estimate the ability of the biomarkers to detect oral squamous cell carcinoma patients. The data reveal that the combination of these four biomarkers provides a good predictive probability of up to 80% (AUC=0.799, p=0.002) for patients with oral squamous cell carcinoma but not patients suffering from oral leukoplakia with dysplasia. Moreover, the combination of only the two biomarkers (SAT and IL-8) also raises a high predictive ability of 75.5% (AUC=0.755, p=0.007) approximately equal to the four biomarkers suggesting the use of the two biomarkers only in the prediction model for oral squamous cell carcinoma patients limiting the economic and health cost in half. SAT and IL-8 mRNAs are present in the saliva in high quality and quantity, with a good discriminatory ability for oral squamous cell carcinoma patients only but not for patients with oral leukoplakia and dysplasia an oral potentially malignant disorder.

    B-RAF inhibitors (BRAFi) have been shown to improve rates of overall and progression-free survival in patients with stage IV metastatic melanoma positive for the BRAF V600E mutation. However, the main drawback is the development of verrucal keratosis (hyperkeratotic papules with verruca-like characteristics with benign histological findings) and cutaneous squamous cell carcinomas (cuSCC). We have found upstream mutations in RAS as well as PIK3CA in both verrucal keratosis and cuSCC. This suggests that verrucal keratosis is an early clinical presentation of cuSCC in patients on BRAFi. © 2012 John Wiley & Sons A/S.

    Basal cell carcinoma (BCC) is the commonest tumor in human. About 70% sporadic BCCs bear somatic mutations in the PATCHED1 tumor suppressor gene which encodes the receptor for the Sonic Hedgehog morphogen (SHH). PATCHED1 germinal mutations are associated with the dominant Nevoid Basal Cell Carcinoma Syndrome (NBCCS), a major hallmark of which is a high susceptibility to BCCs. Although the vast majority of sporadic BCCs arises exclusively in sun exposed skin areas, 40 to 50% BCCs from NBCCS patients develop in non photo-exposed skin. Since overwhelming evidences indicate that microenvironment may both be modified by- and influence the- epithelial tumor, we hypothesized that NBCCS fibroblasts could contribute to BCCs in NBCCS patients, notably those developing in non photo-exposed skin areas. The functional impact of NBCCS fibroblasts was then assessed in organotypic skin cultures with control keratinocytes. Onset of epidermal differentiation was delayed in the presence of primary NBCCS fibroblasts. Unexpectedly, keratinocyte proliferation was severely reduced and showed high levels of nuclear P53 in both organotypic skin cultures and in fibroblast-led conditioning experiments. However, in spite of increased levels of senescence associated β-galactosidase activity in keratinocytes cultured in the presence of medium conditioned by NBCCS fibroblasts, we failed to observe activation of P16 and P21 and then of bona fide features of senescence. Constitutive extinction of P53 in WT keratinocytes resulted in an invasive phenotype in the presence of NBCCS fibroblasts. Finally, we found that expression of SHH was limited to fibroblasts but was dependent on the presence of keratinocytes. Inhibition of SHH binding resulted in improved epidermal morphogenesis. Altogether, these data suggest that the repertoire of diffusible factors (including SHH) expressed by primary NBCCS fibroblasts generate a stress affecting keratinocytes behavior and epidermal homeostasis.

    Full Text Available Small cell carcinoma of the gastrointestinal tract is a rare and aggressive neuroendocrine tumor. This study aims to analyze the clinical characteristics and potential prognostic factors for patients with limited stage small cell carcinoma of the gastrointestinal tract. The records of 27 patients with limited stage small cell carcinoma of the gastrointestinal tract, who all received surgery with lymphadenectomy, were retrieved and analyzed retrospectively. The median age of patients was 60 years old (range 38-79. The primary locations of tumor were the esophagus (74.1% and stomach (14.8%. The rate of preoperative accurate diagnosis (16.7% was low for small cell carcinoma of the esophagus and stomach. 40.7% of all the patients had regional lymph node metastases. Five patients underwent surgery alone, and the other 22 were treated with surgery + postoperative chemotherapy. All patients had disease progression or recurrence. The overall median survival time was 10 months and the 1-year survival rate was 37.0%. Patients who received postoperative chemotherapy had a median survival time of 12 months, which was superior to the 5-month survival of for those who only had surgery (P<0.0001. TNM stage (P=0.02 and postoperative chemotherapy (P<0.0001 were considered as two prognostic factors in univariate analysis. Postoperative chemotherapy was a significant independent prognostic factor in multivariate analysis (P=0.01. The prognosis for patients with limited stage small cell carcinoma of the gastrointestinal tract remains dismal, however, postoperative chemotherapy may have the potential to improve the outcome for these patients.

    Treatment of metastatic renal cell carcinoma comprises metastasectomy±systemic medical treatment. Specific immunotherapy after metastasectomy could be a complementary option. In this phase 1/2 study, safety and tolerability of an adjuvant multi-peptide vaccine (UroRCC) after metastasectomy was evaluated together with immune response and efficacy, compared with a contemporary cohort of patients (n=44) treated with metastasectomy only. Nineteen metastatic renal cell carcinoma patients received UroRCC via intradermal or subcutaneous application randomized to immunoadjuvants (granulocyte-macrophage colony-stimulating factor or Montanide). Adverse events of UroRCC were mainly grade I and II; frequency of immune response was higher for major histocompatibility complex class II peptides (17/19, 89.5%) than for major histocompatibility complex class I peptides (8/19, 42.1%). Median overall survival was not reached in the UroRCC group (mean: 112.6 mo, 95% confidence interval [CI]: 92.1-133.1) and 58.0 mo (95% CI: 32.7-83.2) in the control cohort (p=0.015). UroRCC was an independent prognosticator of overall survival (hazard ratio=0.19, 95% CI: 0.05-0.69, p=0.012). Adjuvant UroRCC multi-peptide vaccine after metastasectomy was well tolerated, immunogenic, and indicates potential clinical benefit when compared with a contemporary control cohort (NCT02429440). The application of a patient-specific peptide vaccine after complete resection of metastases in metastatic renal cell carcinoma patients resulted in favorable tolerability and outcome.

    A rare case of the choroid plexus metastasis of renal-cell carcinoma is reported. A 58-year-old man was admitted on March 3, 1982, with complaints of mild headache and a transient attack of muscle weakness of the left upper extremity. He had undergone a left nephrectomy because of renal-cell carcinoma 2 years before this admission. A CT scan revealed a small mass in the right lateral ventricle that was markedly enhanced by the contrast medium. A carotid angiogram was normal, but a left vertebral angiogram showed a round tumor stain in the distal portion of the right posterior choroidal artery. To determine the nature of the tumor, it was successfully removed via the right frontal transventricular approach. The immediate recovery from the operation was uneventful, but the patient became semicomatose 6 hours later because of a large subdural hematoma over the left hemisphere. An emergency operation for clot removal and external decompression failed to improve the patient's status, and he died on the 3rd postoperative day. An histological examination of the tumor determined the diagnosis of clear-cell-type renal-cell carcinoma. The CT demonstration of choroid plexus metastasis is quite rare. To our knowledge, only two cases have been described.

    Merkel cell carcinoma (MCC) is a rare and aggressive cutaneous neoplasm that has exhibited an exponential increase in incidence in the past 3 decades. Combined MCC and cutaneous squamous cell carcinoma (SCC/MCC) is an uncommon variant of MCC that exhibits worse prognosis than pure MCC. To describe the clinical presentation, dermoscopy, and histology of an unusual subtype of combined SCC/MCC. A 73-year-old white woman presented with an ulcerated and violaceous 10-mm plaque on her right jawline that had been present for 2 to 3 months. On dermoscopy, the lesion was predominantly milky pink to red with peripheral crusting and large-caliber polymorphous vessels. Histology revealed SCC in situ above and adjacent to MCC. The tumor was excised with clear margins, and sentinel lymph node scintography was negative for nodal involvement. © The Author(s) 2016.

    syndrome (GGS is an autosomal dominant inherited disorder that mainly predisposes to the proliferation of tumors, such as basal cell carcinomas and jaw keratocysts. GGS is caused by the Patched gene mutation on chromosome 9. Basal cell carcinomas in patients with GGS usually present as multiple tumors, with polymorphic clinical features, a non-gender predilection, sometimes occurring in the early stages of life, and even affecting areas not exposed to sunlight. The clinical behavior may vary, and sometimes can be very aggressive, especially in the face. In order to study the behavior of basal cell carcinomas in GGS patients, a study was performed on the patients who met criteria for the disease and were treated in our hospital in the period between 2001 and 2011. Material and methods: The study included 11 patients with clinical and/or genetic diagnosis of GGS. The patients were studied according sex and age, clinical aspects, histological features, surgical treatment provided, presence of recurrence, and follow-up. Results: Basal cell carcinomas were seen on the face in 36% of the patients. The number of tumors per patient ranged between 9 and 21. The preferred treatment was surgical excision, although all patients developed new lesions and recurrences which required several procedures. The histological study revealed a contact or proximity of the tumor to surgical margins in 28% of lesions. Conclusions: There is insufficient evidence in the literature to determine the treatment of choice among the different methods available for the management of the basal cell carcinoma in GGS. A preventive approach is necessary to avoid sunlight exposure.

    Controversy persists as regards the indications and results of surgery in the treatment of patients with stage pIIIA-N2 non-small cell lung cancer (NSCLC). The objective of this study was to analyze the overall survival of a multicentre series of these patients and the role of adjuvant treatment, looking for factors that may define subgroups of patients with an increased benefit from this treatment. A retrospective study was conducted on 287 patients, with stage pIIIA-N2 NSCLC subjected to complete resection, taken from a multi-institutional database of 2.994 prospectively collected consecutive patients who underwent surgery for lung cancer. Adjuvant treatment was administered in 238 cases (82.9%). Analyses were made of the age, gender, histological type, administration of induction and adjuvant chemotherapy and/or radiation therapy treatments. The 5-year survival was 24%, with a median survival of 22 months. Survival was 26.5% among patients receiving with adjuvant treatment, versus 10.7% for those without it (P=.069). Age modified the effect of adjuvant treatment on survival (interaction P=.049). In patients under 70 years of age with squamous cell carcinoma, adjuvant treatment reduced the mortality rate by 37% (hazard ratio: 0,63; 95% CI; 0,42-0,95; P=.036). Completely resected patients with stage pIIIA-N2 NSCLC receiving adjuvant treatment reached higher survival rates than those who did not. Maximum benefit was achieved by the subgroup of patients under 70 years of age with squamous cell carcinoma. Copyright © 2012 AEC. Published by Elsevier Espana. All rights reserved.

    To determine, with the use of polymerase chain reaction, the prevalence of human papillomavirus (HPV) 16 in 30 patients with primary oral squamous cell carcinoma (OSCC) and 30 healthy control patients. DNA was extracted from freshly frozen tumor tissues of 30 patients with primary oral squamous cell carcinoma and from the oral mucosa of 30 controls. A pair of specific primers of the E7 early gene of HPV 16 were designed. PCR products were run by 1.5% agarose gel and the results of electrophoresis were photographed. HPV 16 was detected in 36.7% (11/30) of oral squamous cell carcinoma patients and 11.1% (4/30) of controls. HPV 16 has a significant association with oral squamous cell carcinoma. However, the role HPV 16 plays in the tumorigenesis of oral cancer and its clinical significance remain to be investigated.

    Full Text Available Background. The Syndrome of Inappropriate Antidiuretic Hormone (SIADH is considered to be the most common cause of euvolemic hyponatremia. The most common malignancy associated with SIADH is small cell lung cancer. We present a rare case of a patient with SIADH secondary to well differentiated squamous cell carcinoma of the naso-oropharynx. Case. A 46-year-old Caucasian woman presented to emergency department with four-week history of progressive dysphagia. On examination, she was found to have a pharyngeal mass. CT scan and MRI of neck confirmed a mass highly suspicious of carcinoma. Patient’s serum sodium level decreased to 118 mEq/L and other labs including serum and urine osmolality confirmed SIADH. She was started on fluid restriction and oral sodium tablets which gradually improved her serum sodium levels. Biopsy confirmed diagnosis of squamous cell carcinoma of pharynx. Conclusion. SIADH can be caused by squamous cell carcinoma. Appropriate management includes fluid restriction.

Through this study, we understand that kidney disease over the years had higher incidence rates, especially in adults in the sixth decade of life. The renal cell carcinoma (RCC is the third most common malignancy of the genitourinary tract, affecting 2% to 3% of the population. There are numerous ways of diagnosis; however, the most important are ultrasonography, magnetic resonance imaging and computed tomography. In general most of the patients affected by the CCR, have a good prognosis when diagnosed early and subjected to an effective treatment. This study conducted a literature review about the CCR, through this it was possible to understand the development needs of the imaging methods used for precise diagnosis and classification of RCC through the TNM system.

    Full Text Available We report a 24-year-old woman presenting with a relapsed soy-bean-size tender mass at the junction of the soft and hard palate and a history of palatine tumor of small cell carcinoma. Reexcision surgery was performed and histopathological features were consistent. The patient was treated with six cycles of chemotherapy consisting of etoposide and cisplatin. After one year, the patient developed bone metastases and Cushing's syndrome, and successfully recovered with subsequent chemotherapy with irinotecan and cisplatin plus radiotherapy. There was no evidence of recurrence or metastasis for more than three years. Small cell carcinoma originating in the head and neck region has been reported to be highly aggressive and has a poor prognosis. This is the first case report of a patient with relapsed primary small cell carcinoma of the palate and successfully treated with second-line chemotherapy and local radiotherapy.

    To assess the differential imaging findings of metastatic lymph nodes in squamous cell carcinoma (SCC) and non-squamous cell carcinoma (non-SCC) on neck CT and to facilitate the identification of primary focus before performing a biopsy. We retrospectively analyzed 46 patients with SCC and 50 patients with non-SCC who underwent neck CT from January 2006 to January 2011. Patients were divided into two groups; SCC and non-SCC. The total number of lymph nodes was 204 in the SCC group and 530 in the non-SCC group. Two observers were asked to assess the characteristics of abnormal lymph nodes (number, margin types, enhancement patterns, size, bilaterality, calcification, fat infiltration, conglomeration, invasion of adjacent tissue, and nodal distribution). Nodal distribution was evaluated by imaging-based nodal classification on neck CT. Between the SCC group and the non-Succ group except for cases of thyroid cancer, the number of lymph nodes and the number of lymph nodes smaller than 3 cm in the non-Succ group except for cases of thyroid cancer were significantly greater than those in the Succ group (p < 0.05). The number of lymph nodes, the number of lymph nodes smaller than 3 cm, and nodal distribution are helpful in differential diagnosis between Succ and non-Succ before performing a biopsy.

    Thirty-two patients with hepatocellular carcinoma and six patients with renal cell carcinoma for whom the arterial embolization therapy was performed were studied by CT and clinical follow-up for investigating intratumoral gas detected on CT in post-embolization cases. The intratumoral air was found by CT in seven patients with hepatocellular carcinoma and four patients with renal cell carcinoma. The air was composed of a collection of multiple small round gas bubbles in the embolized tumor except in one case where it formed a serpiginous pattern. There was no hematologic nor clinical evidence of liver abscess in all the cases. It was possible to distinguish gas from abscess or fat by a combination of CT and clinical findings.

    Giant basal cell carcinoma, in which the tumour measures 5 cm or greater in diameter, is a very rare skin malignancy that accounts for less than 1 per cent of all basal cell tumours. Very few studies have reported on the incidence, resection and reconstruction of this lesion worldwide. In total, 17 patients with giant basal cell carcinoma of the head and neck region underwent surgical excision and reconstruction at our hospital. Medical charts were retrospectively reviewed and analysed. The lesion was usually in the forehead, eyelid, lips or nasal-cheek region. The greatest diameter ranged from 5 to 11 cm, with 5-6 cm being the most common size at the time of presentation. All patients had their tumour resected and reconstructed in a single-stage procedure, mostly with a local advancement flap, and with no post-operative flap failure. Giant basal cell carcinoma of the head and neck can be successfully treated with a local flap in a single-stage approach.

    Full Text Available Summary: Rarely, basal cell carcinoma grows to a giant size, invading the underlying deep tissue and complicating the treatment and reconstruction modalities. A giant basal cell carcinoma on the scalp is in some cases treated with a combination of surgery and radiation therapy, resulting in local control, a satisfactory long-term cosmetic and functional result. We present a case with a neglected basal cell scalp carcinoma, treated with wide excision and postoperative radiotherapy, reconstructed with a free latissimus dorsi flap. The cosmetic result is acceptable and there is no sign of recurrence 1 year postoperatively.

    Merkel cell carcinoma is a rare, highly aggressive cutaneous neuroendocrine carcinoma most commonly seen in sun-damaged skin. Histologically, the tumor consists of primitive round cells with fine chromatin and numerous mitoses. Immunohistochemical stains demonstrate expression of neuroendocrine markers. In addition, cytokeratin 20 (CK20) is expressed in ∼95% of cases. In 2008, Merkel cell carcinoma was shown to be associated with a virus now known as Merkel cell polyomavirus in ∼80% of cases. Prognostic and mechanistic differences between Merkel cell polyomavirus-positive and Merkel cell polyomavirus-negative Merkel cell carcinoma may exist. There has been the suggestion that CK20-negative Merkel cell carcinomas less frequently harbor Merkel cell polyomavirus, but a systematic investigation for Merkel cell polyomavirus incidence in CK20-negative Merkel cell carcinoma has not been done. To test the hypothesis that Merkel cell polyomavirus is less frequently associated with CK20-negative Merkel cell carcinoma, we investigated 13 CK20-negative Merkel cell carcinomas from the files of the Cleveland Clinic and the University of Michigan for the virus. The presence or absence of Merkel cell polyomavirus was determined by quantitative PCR performed for Large T and small T antigens, with sequencing of PCR products to confirm the presence of Merkel cell polyomavirus. Ten of these (77%) were negative for Merkel cell polyomavirus and three (23%) were positive for Merkel cell polyomavirus. Merkel cell polyomavirus is less common in CK20-negative Merkel cell carcinoma. Larger series and clinical follow-up may help to determine whether CK20-negative Merkel cell carcinoma is mechanistically and prognostically unique.

    Improving technologies for the detection and purification of bone marrow (BM) micrometastatic cells in breast cancer patients should lead to earlier prognosis of the risk of relapse and should make it possible to design more appropriate therapies. The technique used has to overcome the challenges resulting from the small number of target cells (one per million hematopoietic cells) and the heterogeneous expression of micrometastatic cell markers. In the present study, we have assessed the clinical relevance of current methods aimed at detecting rare disseminated carcinoma cells. BM aspirates from 32 carcinoma patients were screened for the presence of micrometastatic cells positive for epithelial cell adhesion molecule and positive for cytokeratins, using optimized immunodetection methods. A comparison with data obtained for 46 control BM aspirates and a correlation with the clinical status of patients were performed. We developed a sensitive and efficient immunomagnetic protocol for the enrichment of BM micrometastases. This method was used to divide 32 breast carcinoma patients into three categories according to their epithelial cell adhesion molecule status. These categories were highly correlated with the recently revised American Joint Committee on Cancer staging system for breast cancer, demonstrating the clinical relevance of this simple and reliable immunomagnetic technique. We also evaluated immunocytochemical detection of cytokeratin-positive cells and cytomorphological parameters. Immunocytochemistry-based methods for the detection of BM micrometastases did not provide any information about the clinical status of patients, but helped to refine the immunomagnetic data by confirming the presence of micrometastases in some cases. We also tested a new density gradient centrifugation system, able to enrich the tumor fraction of BM specimens by twofold to threefold as compared with standard Ficoll methods. These improved methods for the detection of

    The expression of E74-like factor 5 (ELF5) in epithelial ovarian carcinoma tissues and its effects on biological behavior in ovarian carcinoma cells were assessed in search for a new approach for gene treatment of epithelial ovarian carcinoma. RT-PCR technology was applied to detect the expression of ELF5 mRNA in epithelial ovarian carcinoma (n=49), borderline ovarian epithelial tumor (n=19), benign ovarian epithelial tumor (n=31) and normal ovarian tissues (n=40). Then, we transfected recombinant plasmid pcDNA3.1‑ELF5+EGFP into human ovarian carcinoma SKOV3 cells (recombinant plasmid group) in vitro and screened out stably transfected cells to conduct multiplication culture. Western blot analysis was performed to detect the expression of ELF5 protein in the different groups. Flow cytometry was employed to detect cell apoptosis and cycles. ELF5 mRNA in epithelial ovarian carcinoma and borderline ovarian epithelial tumor tissues were significantly lower (Pepithelial tumor and normal ovarian tissues. ELF5 protein expression in the cells of recombinant plasmid group was significantly higher compared with empty plasmid and blank control groups. The capacity of cell reproductive recombinant plasmid group at each time point decreased (P<0.05). Flow cytometry detection showed that 67.03% of cells in recombinant plasmid group was blocked in G0/G1 phase (P<0.05), compared with empty plasmid group (37.17%) and blank control group (38.24%). Apoptotic rate of recombinant plasmid group was significantly lower (31.4±1.9%; P<0.05), compared with that of empty plasmid group (9.1±2.2%) and blank control group (8.7±1.5%), and the differences were statistically significant. In conclusion, ELF5 interfered with cell cycle of human ovarian carcinoma SKOV3 cells and promoted apoptosis of human ovarian carcinoma SKOV3 cells inhibiting their growth and invasive capacity; and thus providing a new approach to gene treatment of ovarian carcinoma.

    Morphological changes are analysed and morphological assessment of the parenchyma, stroma, vessels and necrosis are provided in the squamous cell lung carcinoma tissue of 40 patients without preliminary irradiation, 40 patients after γ-beam therapy and 49 patients after radiotherapy combined with induced hyperglycemia (IH). The total focal dosage was 20 Gy (5 fractions during a week). In 25 patients IH was followed by irradiation and in 24 patients it followed irradiation. Operation was performed on the 7-8th day after therapy was initiated. It was concluded that preoperative γ-beam therapy followed by IH produced the most noticeable damaging effect on squamous cell lung carcinoma

    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.

    Monoclonal antibodies that block immune regulatory proteins such as programmed death-1 (PD-1) have demonstrated remarkable efficacy in controlling the growth of multiple tumor types. Unresectable or metastatic basal cell carcinoma, however, has largely gone untested. Because PD-Ligand-1 (PD-L1) expression in other tumor types has been associated with response to anti-PD-1, we investigated the expression of PD-L1 and its association with PD-1 expression in the basal cell carcinoma tumor microenvironment. Among 40 basal cell carcinoma specimens, 9/40 (22%) demonstrated PD-L1 expression on tumor cells, and 33/40 (82%) demonstrated PD-L1 expression on tumor-infiltrating lymphocytes and associated macrophages. PD-L1 was observed in close geographic association to PD-1+ tumor infiltrating lymphocytes. Additionally, we present, here, the first report of an objective anti-tumor response to pembrolizumab (anti-PD-1) in a patient with metastatic PD-L1 (+) basal cell carcinoma, whose disease had previously progressed through hedgehog pathway-directed therapy. The patient remains in a partial response 14 months after initiation of therapy. Taken together, our findings provide a rationale for testing anti-PD-1 therapy in patients with advanced basal cell carcinoma, either as initial treatment or after acquired resistance to hedgehog pathway inhibition.

    Background and purpose: To assess the usefulness of pathological stage according to the 7th edition of the Union for International Cancer Control–American Joint Committee on Cancer (UICC–AJCC) as a prognostic tool in patients undergoing neoadjuvant chemoradiation followed by esophagectomy (trimodality therapy, TMT) for locally advanced esophageal squamous cell carcinoma. Material and methods: One hundred twenty-five eligible patients completing TMT were enrolled for analysis. The clinical (cTNM7) and pathological (ypTNM7) stage groups of their tumors were prospectively classified, and re-grouped by the 6th edition (ypTNM6). Survival was analyzed using the Kaplan–Meier method. The Cox proportional hazard model and the Akaike information criterion (AIC) were used to compare the performance of staging systems. Results: With a median follow-up of 24.6 months, 54 patients (43.2%) died. Forty patients (32%) achieved pathological complete remission (pCR). The median survival was 31.8 months. On multivariate analysis, ypTNM7 (but not pCR or pN) was the only independent factor affecting overall survival (p < 0.001). The ypTNM7 was superior to cTNM7 or ypTNM6 in predicting both overall and recurrence-free survival after TMT based on AIC values and Cox proportional hazard model analysis. Conclusions: In patients with locally advanced esophageal squamous cell carcinoma undergoing TMT, ypTNM7 is the best predictor of survival

    Between November 1981 to May 1985, measurements were made of the exponential regression of 69 cervical nodes from 37 patients with squamous cell carcinoma treated with radiotherapy in the division of clinical oncology, the department of Radiology at the Tokyo Women's Medical College. The volume-halving time (T 1/2(V)) which was calculated in each case was analysed. The results were as follows. 1. T 1/2(V) of oral cavity, lung, hypopharynx and esophagus seemed to be longer than those of oropharynx, uterus, larynx and epipharynx. 2. T 1/2(V) of well differentiated squamous cell carcinoma seemed to be shorter than those of moderately and poorly differentiated squamous cell carcinoma, however no significant difference was found. 3. There were two patterns of initial regression. One half of lymph nodes regressed with an initial shoulder and the other half regressed without it. And T 1/2(V) of regression curve with it was statistically shorter than that without it. 4. There was no significant correlation between T 1/2(V) and the lymph node size. 5. The response rate of lymph node to radiotherapy was higher and the regrowth rate was lower in the fast regression group, compared with those in the slow regression group. (author)

    At the Proton Medical Research Centre, University of Tsukuba, a pilot study of proton-beam radiotherapy was performed in 12 patients with the following types of carcinoma: Bowen's disease (4), oral verrucous carcinoma (5), and squamous cell carcinoma (3). They received total doses of 51-99.2 Gy in fractions of 2-12.5 Gy. All tumours responded well to the treatment. All four lesions of Bowen's disease, three of the five oral verrucous carcinomas, and the three squamous cell carcinomas completely regressed following irradiation. Two squamous cell carcinomas recurred during the follow-up period. One recurrent squamous cell carcinoma was successfully treated by a salvage surgical operation, and in the other case the patient refused further therapy. In two verrucous carcinomas there was 90% regression of tumour volume. No severe radiation-related complication occurred. (Author)

    Merkel cell carcinoma is an ultra-rare cutaneous neuroendocrine cancer for which approved treatment options are lacking. To better understand potential actionability, the genomic landscape of Merkel cell cancers was assessed. The molecular aberrations in 17 patients with Merkel cell carcinoma were, on physician request, tested in a Clinical Laboratory Improvement Amendments (CLIA) laboratory (Foundation Medicine, Cambridge, MA) using next-generation sequencing (182 or 236 genes) and analyzed by N-of-One, Inc. (Lexington, MA). There were 30 genes harboring aberrations and 60 distinct molecular alterations identified in this patient population. The most common abnormalities involved the TP53 gene (12/17 [71% of patients]) and the cell cycle pathway (CDKN2A/B, CDKN2C or RB1) (12/17 [71%]). Abnormalities also were observed in the PI3K/AKT/mTOR pathway (AKT2, FBXW7, NF1, PIK3CA, PIK3R1, PTEN or RICTOR) (9/17 [53%]) and DNA repair genes (ATM, BAP1, BRCA1/2, CHEK2, FANCA or MLH1) (5/17 [29%]). Possible cognate targeted therapies, including FDA-approved drugs, could be identified in most of the patients (16/17 [94%]). In summary, Merkel cell carcinomas were characterized by multiple distinct aberrations that were unique in the majority of analyzed cases. Most patients had theoretically actionable alterations. These results provide a framework for investigating tailored combinations of matched therapies in Merkel cell carcinoma patients.

    Full Text Available Oral squamous cell carcinoma (OSCC is the most common epithelial malignancy affecting the oral cavity. The most common sites for the development are lateral surface of tongue and floor of mouth; the least common sites are soft palate, gingiva, and buccal mucosa. Gingival squamous cell carcinoma can mimic a multitude of oral lesions and enlargements, especially those of inflammatory origin. In addition, predisposing and presenting factors are different from those of other OSCCs. Careful examination as well as routine biopsy are crucial for accurate diagnosis.

    Male breast cancer is a rare entity accounting for Nipple skin/subcutaneous tumors in men are even rarer. Likewise, true neuroendocrine carcinoma of the breast, defined as > 50% of tumor cells staining for either chromogranin or synaptophysin, is not a common entity, usually occurring in older women. We present the case of a 70-year-old man with a slowly growing nipple mass that had enlarged over the previous 1.5 years. The histology consisted of nests, trabeculae and sheets of basaloid cells with rare abortive gland formation and a pushing edge. The case was originally misdiagnosed as a Merkel cell carcinoma, based largely on histologic morphology. Strong staining for synaptophysin (in greater than 50% of cells), CD56, keratins AE1 : AE3 and Cam 5.2, as well as estrogen receptor and progesterone receptor was noted. Myoepithelial cells within in situ areas were identified using stains for calponin and 4A4, supporting a primary mammary duct origin. Additionally, a substantial portion of cells stained for Gross Cystic Disease Fluid Protein-15 (GCDFP-15), confirming some overlap with sweat duct differentiation. To the best of our knowledge, although reported in the male breast, no case of primary nipple neuroendocrine carcinoma in a male patient has been reported in the literature. The gender of the patient and association with the skin of the chest wall probably contributed to the original misdiagnosis of Merkel cell carcinoma in this patient.

    Full Text Available We present an unusual case of concurrent occurrence of a multilocular cystic renal cell carcinoma and a leiomyoma in the same kidney of a patient with no evident clinical symptoms. A 38-year-old man was found incidentally to have a cystic right renal mass on computed tomography. Laparoscopic radical nephrectomy was performed under a preoperative diagnosis of cystic renal cell carcinoma. Histology revealed a multilocular cystic renal cell carcinoma and a leiomyoma. This is the first report of this kind of presentation.

    Full Text Available Background and objective Treatment options for patients with squamous cell carcinoma of the lung (SCC are limited in chemotherapy. However, not all patients could benefit form standard platinum regimen. Considering the dismal prognosis of patients with advanced SCC, a greater focus on selecting sensitive chemotherapy regimens remains of upmost importance to improve outcomes in this disease. In this study, we used matrix-assisted laser desorption/ionization time-of-flight mass spectrometry to detect pre-chemotherapy serum peptides in advanced lung squamous cell carcinoma patients accepting paclitaxel combined with platinum chemotherapy and to analyze the correlation between serum peptides and chemotherapy efficacy. Methods Patients with advanced lung squamous cell carcinoma received paclitaxel combining with platinum chemotherapy and evaluated the efficacy every two cycles. Evaluation of complete response (CR or partial response (PR patients defined as sensitive group, progressive disease (PD patients defined as resistant group. Serum samples were collected from patients with lung squamous cell carcinoma. Eighty-one patients were randomly divided into training group (sensitive group I and resistant group I and validation group (sensitive group II and resistant group II according to the ratio of 3:1. Serum samples were pretreated and Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS was used to detect serum peptide fingerprints. ClinProTools software was used to analyze the differences between the sensitive group I and the resistant group I. Three kinds of biological algorithms (SNN, GA, QC built in CPT software were used to establish the curative effect prediction model respectively and the optimal algorithm was selected. The validation group was used for blind verification. Results Thirty sensitive patients and 31 resistant patients were enrolled in the training group. Ten sensitive patients and 10

    Highlights: •Nesfatin-1 inhibits the proliferation and growth of HO-8910 cells by G1 phase arrest. •Nesfatin-1 enhances HO-8910 cell apoptosis. •Nesfatin-1 inhibits HO-8910 cell proliferation via mTOR and RhoA/ROCK signaling pathway. •The first report of nesfatin-1-mediated proliferation in ovarian epithelial carcinoma. -- Abstract: Nesfatin-1, an 82-amino-acid peptide derived from a 396-amino-acid precursor protein nucleobindin 2 (NUCB2), was originally identified in hypothalamic nuclei involved in the regulation of food intake. It was recently reported that nesfatin-1 is a novel depot specific adipokine preferentially produced by subcutaneous tissue, with obesity- and food deprivation-regulated expression. Although a relation between ovarian cancer mortality and obesity has been previously established, a role of nesfatin-1 in ovarian epithelial carcinoma remains unknown. The aim of the present study is to examine the effect of nesfatin-1 on ovary carcinoma cells proliferation. We found that nesfatin-1 inhibits the proliferation and growth of HO-8910 cells by G1 phase arrest, this inhibition could be abolished by nesfatin-1 neutralizing antibody. Nesfatin-1 enhances HO-8910 cell apoptosis, activation of mammalian target of rapamycin (mTOR) and RhoA/ROCK signaling pathway block the effects of nesfatin-1-induced apoptosis, therefore reverses the inhibition of HO-8910 cell proliferation by nesfatin-1. In conclusion, the present study demonstrated that nesfatin-1 can inhibit the proliferation in human ovarian epithelial carcinoma cell line HO-8910 cells through inducing apoptosis via mTOR and RhoA/ROCK signaling pathway. This study provides a novel regulatory signaling pathway of nesfatin-1-regulated ovarian epithelial carcinoma growth and may contribute to ovarian cancer prevention and therapy, especially in obese patients

    To describe the clinical characteristics, treatment patterns and outcomes in advanced small cell bladder cancer (aSCBC) patients and compare to those with urothelial carcinoma (UC). Individuals in the National Cancer Data Base with a diagnosis of either nodal (TxN+M0) or distant metastatic (TxNxM1) disease were identified from 1998 to 2010. We assessed the relationships between stage, treatment modalities and survival in the aSCBC cohort and compared these to UC patients. In the 960 patient aSCBC cohort (62% M1), 50% received palliative therapy alone, 68% in M1 versus 21% in M0 groups (P < 0.0001). Single modality local therapy (15%) and surgical (21%) or radiation-based (14%) multimodal therapy (MMT) were used in the other 50%. Cystectomy-based MMT was utilized in 45% of N+M0 versus 6.4% of NxM1 patients (P < 0.0001). Median overall survival (OS) for aSCBC patients was 8.6 months; 13.0 months in N+M0 versus 5.3 months in NxM1 patients (P < 0.0001). Survival was similar between TxN1M0 and TxN2-3M0 patients (14.8 months vs. 12.1 months, P = 0.15). Urothelial carcinoma patients (n = 27,796, 45% M1) lived longer compared to aSCBC patients in the N+M0 group (17.3 months vs. 13.0 months, P = 0.0007). There were not clinically significant differences in OS between UC and aSCBC patients in the M1 group. Advanced SCBC is a rare disease with a poor survival and palliative therapy is common, especially in M1 patients. In comparison to UC, the outcomes for aSCBC patients are worse in those with lymph node only involvement but similar in those with distant disease

    Tobacco and alcohol consumption are considered the main risk factors for oral squamous cell carcinoma (OSCC); however, the role of these factors in patients younger than 40 years is controversial, so it has been suggested that genomic instability and high-risk human papillomavirus (HR-HPV) infection may be contributing factors to oral carcinogenesis at a young age. Therefore, the aim of this study was to evaluate the immunoexpression of cell cycle proteins according HPV status in OSCC affecting young patients. A tissue microarray construction based on 34 OSCC samples from young patients (factor receptor, p53, and p16 antibodies. The clinicopathologic features and the immunoexpression of all tested proteins were similar in both groups. Patients with HPV-related OSSC tended to have better cancer-specific survival (CSS; 39% vs 60% 5-y CSS), and overall survival (OS; 29.2% vs 60% 5-year OS). However, this difference was not statistically significant. No significant difference exists in the expression of cell cycle proteins studied between HR-HPV DNA-positive and HR-HPV DNA-negative OSCC affecting young patients. Copyright © 2018 Elsevier Inc.

    The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice. A 55-year-old postmenopausal woman, gravida 5 para 5, with past medical history significant for hypertension, presented to the emergency department with profuse vaginal bleeding and a hemoglobin level of 9 g/dL. The biopsy from an irregular 6-cm cervical mass was consistent with moderately differentiated cervical squamous cell carcinoma. The physical examination did not reveal vaginal or parametrial extension of the tumor. Pelvic magnetic resonance imaging disclosed the known carcinoma, as well as a 9.2 × 7.7 × 6.7 cm anterior uterine fibroid (Fig 1). A staging positron emission tomography scan was negative for metastatic disease. After blood transfusion and vaginal packing, the patient was referred to discuss the immediate management of her newly diagnosed bleeding bulky cervical cancer. In the absence of parametrial or vaginal extension and in the absence of lymph node metastasis (both on clinical examination and imaging), she was classified as having International Federation of Gynecology and Obstetrics stage IB2 disease.

    Lymphatic vessel spread is considered a major route for head and neck squamous cell carcinoma metastasis. Formation of new lymphatic vessels could facilitate the process, raising the malignant potential of these tumours. Recent identification of lymphatic markers allows the study of the lymphangiogenesis phenomenon. We searched for molecular events involved in the lymphangiogenic process that could have prognostic value in laryngeal/pharyngeal carcinoma patients. 104 paraffin-embedded pharyngeal/laryngeal tumour samples were studied. Immunohistochemical analysis of podoplanin and double immunofluorescence analysis of Ki-67 and D2-40 were performed. Lymph vessel density (inside the tumour mass, at its periphery or considered as a whole) and the presence of tumour emboli inside lymphatics were recorded. The proliferative state of endothelial lymphatic cells was evaluated. Lymphatic vessels were detected inside the tumour mass (75%) and in the surrounding tissue (80%); some of them in a proliferative state. Tumour emboli were detected in a high proportion of the cases (45%). Lymphatic vessel density was higher in the pharyngeal cases (p = 0.0029), in greater size (p = 0.039), more advanced stage primary tumours (p = 0.006) and in carcinomas of patients with affected nodes (p = 0.019). The presence of tumour emboli and a high global vessel density were indicators of poor prognosis (recorded as death from tumour) in the laryngeal group (p = 0.015 and p = 0.027, respectively), but notably not in the pharyngeal one. Interestingly, high global vessel density showed a negative prognostic value among pathologically staged N0 laryngeal carcinomas (p = 0.03). The lymphangiogenic process correlated with aggressive tumour features (pN category, tumour size, tumour stage), but might play different roles in tumours arising from different anatomic sites. Our results suggest that detection of tumour emboli and assessment of global vessel density using the D2-40 antibody, may be

    Full Text Available We report a rare case of severe hypoglycemia after sunitinib treatment for pancreatic neuroendocrine carcinoma. We describe the initial clinical presentation, laboratory results, pathologic findings, and managment in a patient with a nonfunctioning pancreatic neuroendocrine carcinoma with liver metastases who developed life threatening hypoglycemia after 2 months of sunitinib therapy. A 46-year-old woman presented to the emergency department with loss of consciousness from hypoglycemia. Serum C-peptide and insulin levels at fasting state revealed that the hypoglycemia resulted from endogenous hyperinsulinemia. She had been diagnosed with nonfunctioning pancreatic neuroendocrine carcinoma based on a biopsy of metastatic cervical lymph node and was being treated with sunitinib, a small molecule tyrosine kinase inhibitor. Immunohistochemical stain of the metastatic liver mass demonstrated that the initially nonfunctioning neuroendocrine carcinoma cells had changed into insulin-producing cells after sunitinib therapy. Transarterial chemoembolization of the liver masses and systemic chemotherapy with streptozotocin/adriamycin relieved the hypoglycemia. A nonfunctioning pancreatic neuroendocrine carcinoma was transformed into an insulin-producing tumor after treatment with sunitinib, causing endogenous hyperinsulinemia and severe hypoglycemia.

    This retrospective study aimed to evaluate the feasibility and effectiveness of radiofrequency ablation (RFA) in patients with solitary kidney for the treatment of renal cell carcinoma (RCC). Within 2 years 10 patients (seven males, three females; age 65 ± 8 years) were treated. All patients had a history of nephrectomy of the contralateral kidney. The indications for RFA were inoperability or high probability of complete renal failure after surgical enucleation of the tumor. 13 tumors with a size between 1.9 and 4.2 cm (average 2.7 cm) were treated. In patients with a tumor diameter larger than 2.5 cm a transarterial embolization was performed prior to RFA to reduce heat sink effect and risk of bleeding. Therapeutical success was defined as a lack of contrast enhancement in follow up examinations and shrinking of the treated area. Furthermore all patients' renal function was monitored. RFA of renal tumors under CT-fluoroscopy was feasible in all patients. Within the follow up (3 and 24 months) no tumor recurrence or major complication was detected. One patient developed another RCC and was successfully treated with a second RF-ablation. None of the patients developed renal failure with the need of hemodialysis. In one of the patients a hemorrhage into the surrounding tissue was noticed, which stopped spontaneously. RFA is a valuable and effective therapeutical option in patients with solitary kidney suffering from inoperable renal cell carcinoma. The complication rate is small and an excellent tumor control can be achieved without deterioration of the renal function.

    Pancreatic acinar cell carcinoma is an uncommon neoplasm of the exocrine pancreas associated with a poor prognosis, especially when found to be metastatic. Since there are a lack of large studies and prospective, randomized data, no consensus treatment guidelines are available. Here, we report a case of a patient with recurrent metastatic acinar cell carcinoma involving the liver who had presented initially with pancreatic panniculitis. She received chemotherapy with capecitabine and oxaliplatin prior to resection of her primary tumor and liver metastases, after which she experienced a 30 months recurrence-free survival. Upon relapse, she was treated with a combination of capecitabine and oxaliplatin followed by maintenance capecitabine. Now, more than seven years after initial diagnosis, the patient remains stable without evidence of active disease. This case highlights the possibility of therapeutic success even for a patient initially deemed unresectable due to a poor performance status who responded to fluoropyrimidine-based therapy.

    Renal cell carcinoma (RCC) is a malignant lethal tumour with high potential of metastasis. However, metastasis from RCC to the skin is much less common. It is virtually a sign of poor prognosis. We represent a 42 years old man with bilateral RCC of clear cell type followed by metastasis to the scalp one month later. In this case the relatively young age of the patient, bilaterality of RCC and occurance of skin metastasis in the absence of recurrent kidney tumour are interesting.

    Renal cell carcinoma (RCC) is currently one of the most frequent urological malignancies. One of the important histological findings, which reflect biological behaviour of RCC and also provide significant prognostic data are sarcomatoid changes of tumor. In our paper we evaluated the incidence of sarcomatoid changes in renal cell carcinomas and their relationship with other clinico-pathological parameters. A study group consisted of 159 cancers from 157 patients (95 men, 62 women) in the age rage from 18 to 82 years. Out of all cases we found 18 carcinomas (11.3%) having varying degrees of sarcomatoid changes. These tumors were obtained from 18 subjects (11 men, 7 women) between 45 and 82 years of age (mean age 69.1 years). Among them, there were 13 conventional clear cell RCCs, 1 papillary RCC, 2 unclassified RCCs and 2 carcinomas, that entirely consisted of sarcomatoid tissue, were classified as sarcomatoid RCCs. Histologically, sarcomatoid component predominantly composed of spindle cells population with varying degrees of anaplasia and sometimes exhibited rhabdoid features. Six cases corresponded to the pathological stage limited to the kidney (pT1 and pT2) and ten cases were diagnosed in pathological stage with extrarenal propagation (pT3 and pT4). Four patients had metastases in the regional lymph nodes. Almost all cancers showed necrosis. Since sarcomatoid changes in RCC are usually associated with negative prognostic parameters and much less favourable prognosis of disease, if present, pathologist must describe them in a biopsy report. From a clinical point of view, these patients require more careful follow-up, as the literature data indicate the majority of them have metastases at the time of diagnosis. (author)

    Objective: To observing the relationship between apoptosis-related genes bcl-2,c-myc, p53 and the radiosensitivity of esophageal squamous cell carcinoma. Methods: The expression levels of bcl-2, c-myc and p53 genes in 57 biopsy samples from patients of esophageal squamous cell carcinoma were detected with the LSAB immunohistochemistry method. All the patients were treated with radiotherapy. The radiotherapeutic effect in these patients was observed and the relation between gene expression and radiosensitivity was analyzed. Results: Compared with the bcl-2-negative group, the radiosensitivity of bcl-2-positive one was lower(P<0.01). The radiosensitivity of p53-positive group was slightly lower than that of the p53-negative one (P<0.05). The c-myc protein expression was not related to radiosensitivity. Conclusion: Detection and comprehensive analysis of bcl-2, c-myc and p53 protein expressions are useful in forecasting the radiotherapeutic effect on squamous cell carcinoma of esophagus

The discovery of the Merkel cell polyomavirus (MCPyV) in 2008 significantly impacted the understanding of the etiopathogenesis of MCC. MCPyV is clonally integrated into the MCC genome and approximately 80% of MCC are MCPyV-positive. Recent results of clinical trials using blockade of the PD-1 immune modulatory pathway are promising for the future treatment of MCC. Despite this major progress of the past few years, the cellular origin of MCC still remains obscure. Based on histomorphology, gene expression profiling, and molecular analyses, we have recently hypothesized that MCC originates from pre‑/pro-B cells. Here we review putative cells of MCC, including Merkel cells, (epi‑)dermal stem cells, and pro‑/pre-B cells. In the present work, the focus is on the concept of pre‑/pro-B cells as the cellular origin of MCC, which might also impact the understanding of other human small cell malignancies of unknown cellular origin, such as small cell carcinomas of the lung and other anatomical locations. In addition, this concept might pave the way for novel treatment options, especially for advanced MCC.

    Full Text Available Metastasis of renal cell carcinoma to the pancreas is uncommon and, in most cases, presents as a single pancreatic mass that shows a more favorable prognosis than primary pancreatic tumors. We examined patients with renal cell carcinoma metastatic to the pancreas, and discuss the clinical findings, treatment administered, and final outcomes. The present study is a retrospective analysis of renal cell carcinoma patients with pancreatic metastasis. Pancreatic tumor specimens were obtained by surgical excision, surgical biopsy, fine-needle biopsy, or endoscopic ultrasound biopsy. The surgical approaches included distal splenopancreatectomy, total pancreatectomy, or distal pancreatectomy. The physician determined the postoperative treatment regimen with interferon-α or targeted therapy on the basis of patient's performance. A total of six patients with median age of 50 years were included in the study. The median time from the primary nephrectomy to the development of pancreatic metastasis was 16 years. In the biopsy-only group, the mean stable disease period was 16.5 months. In the patients treated with surgery combined with interferon-α or targeted therapy, the mean stable disease period was 29.5 months. The patients treated with repeat mastectomy showed a mean stable disease period of 33.3 months. Aggressive surgical management is more effective than observation or immunotherapy. Recent advances in the design of targeted therapies may provide alternative treatment strategies. Combination therapy may play an important role in the future. Considering patient compliance and cost-effectiveness, resection of pancreatic metastasis is currently the first choice of treatment.

    Merkel cell carcinoma is believed to be derived from Merkel cells after infection by Merkel cell polyomavirus (MCPyV) and other poorly understood events. Transcriptional profiling using cDNA microarrays was performed on cells from MCPy-negative and MCPy-positive Merkel cell carcinomas and isolated normal Merkel cells. This microarray revealed numerous significantly upregulated genes and some downregulated genes. The extensive list of genes that were identified in these experiments provides a large body of potentially valuable information of Merkel cell carcinoma carcinogenesis and could represent a source of potential targets for cancer therapy. © 2014 John Wiley & Sons A/S.

    2011-10-01

    Full Text Available Abstract Patients with ESCC (squamous cell carcinoma of the esophagus are most commonly diagnosed with locally advanced tumor stages. Early metastatic disease and late diagnosis are common reasons responsible for this tumor's poor clinical outcome. The prognosis of esophageal cancer is very poor because patients usually do not have symptoms in early disease stages. Squamous cell carcinoma of the esophagus frequently complicates patients with multiple co-morbidities and these patients often require interdisciplinary diagnosis and treatment procedures. At present time, neoadjuvant radiation therapy and chemotherapy followed by surgery are regarded as the international standard of care. Meta-analyses have confirmed that this approach provides the patient with better local tumor control and an increased overall survival rate. It is recommended that patients with positive tumor response to neoadjuvant therapy and who are poor surgical candidates should consider definitive radiochemotherapy without surgery as a treatment option. In future, EGFR antibodies may also be administered to patients during therapy to improve the current treatment effectiveness. Positron-emission tomography proves to be an early response-imaging tool used to evaluate the effect of the neoadjuvant therapy and could be used as a predictive factor for the survival rate in ESCC. The percentage proportions of residual tumor cells in the histopathological analyses represent a gold standard for evaluating the response rate to radiochemotherapy. In the future, early response evaluation and molecular biological tests could be important diagnostic tools in influencing the treatment decisions of ESCC patients.

    BACKGROUND: Basal cell carcinomas are the most prevalent of all skin cancers worldwide and form the majority of the surgical workload for most modern cutaneous malignancy centres. Primary surgical removal of basal cell carcinomas remains the gold standard of treatment but, despite almost two centuries of surgical experience, rates of incomplete surgical excision of up to 50% are still reported. The aim of this study was to assess, quantify and perform comparative analysis of the outcomes and predictive factors of consecutive primarily-excised basal cell carcinomas in a tertiary centre over a six-year period. METHODS: Retrospective audit was conducted on all patients who underwent surgical excision of basal cell carcinomas from January 2000 to December 2005. Assessment parameters included patient biographics, tumour management differences and detailed histopathological analysis of tumour margins and subtypes. RESULTS: One thousand eight hundred and thirty two basal cell carcinomas were excised from 1329 patients over the designated time period. Two hundred and fifty one (14%) lesions were incompletely excised with 135 (7.4%) involving the peripheral margin only, 48 (2.6%) the deep margin only and 41 (2.2%) involving both. Nasal location was the most common predictor of incomplete excision. CONCLUSIONS: Overall basal cell carcinomas excision rates compared favourably with international reported standards but attention to a variety of surgical and histological risk factors may improve this further.

    2008-12-01

    Full Text Available Abstract Background Squamous cells are normally not found inside the breast, so a primary squamous cell carcinoma of the breast is an exceptional phenomenon. There is a possible explanation for these findings. Case presentation A 72-year-old woman presented with a breast abnormality suspected for breast carcinoma. After the operation the pathological examination revealed a primary squamous cell carcinoma of the breast. Conclusion The presentation of squamous cell carcinoma could be similar to that of an adenocarcinoma. However, a squamous cell carcinoma of the breast could also develop from a complicated breast cyst or abscess. Therefore, pathological examination of these apparent benign abnormalities is mandatory.

    A new cell line of human uterine endometrial undifferentiated carcinoma, designated as TMG-L, was established from the metastatic lymph node of 56-year-old patient TMG-L cells have been cultured with Ham's F-12 medium supplemented with 10% FCS and grew as a loosely adherent monolayer with polygonal or spindle-shaped cells exhibiting poor cell-cell contact and piled up against each other, showing a tendency to grow as floating cells. The doubling time of this cell line was about 48 hours, and chromosomal analysis revealed aneuploidy at passage 25. The cells formed tumors in SCID mouse, the histology of which was similar to that of undifferentiated carcinoma component of primary tumor. TMG-L cells showed the loss of expression and membranous localization of either E-cadherin or alpha-catenin, implied corresponding loss of their adhesive function. And this dysfunction implicated the biological aggressive behavior of uterine endometrial undifferentiated carcinoma. This cell line appears to provide a useful system for studying uterine undifferentiated carcinoma in vivo and in vitro.

    Objective: to evaluate the role of computed tomography in the assessment of deep extension of squamous cell carcinoma of the external auditory canal. Materials and methods: in the period between May 1995 and December 2003 six patients with squamous cell carcinoma of the external auditory canal were submitted to computed tomography scan at 'Hospital Heliopolis', Sao Paulo, SP, Brazil, including axial and coronal slices with soft tissue and bone algorithms. Results: thickening of the soft tissue of the external auditory canal was seen in all patients, bone erosion and invasion of the middle ear in five (83.3%), invasion of the mastoid and parotid gland in four (66.7%), invasion of the temporomandibular joint in three (50%), and invasion of the middle cranial fossa, carotid canal and cervical lymph node enlargement in two (33.3%) patients. Conclusion: assessment of deep extension of squamous cell carcinoma of the external auditory canal using computed tomography is useful for clinical staging of the disease allowing better therapeutic planning for these patients.

    Objective: To assess the usefulness of computerized tomography (CT) in the characterization of renal masses, in order to stage them, determine their prognosis and their appropriate clinical and/or surgical management. Material and Methods: Between 1988 and 2001, we selected 63 patients with renal tumors that had been examined by pathology. Patient's ages ranged from 16 to 88 years (25 women, 38 men). The studies were performed with a sequential helical CT, using 5 mm thickness sections every 5mm evaluating the cortico medullar and nephrographic phases. Renal tumors were characterized and staged without any knowledge about the pathological findings; subsequently the tomographic characteristics were compared to such findings. The following characteristics were evaluated: 1) mixed solid-cystic nature; 2) size; 3) borders; 4) enhancement; 5) necrosis; 6) hemorrhage; 7) central scar; 8) presence of fat; 9) collecting system; 10) capsular invasion; 11) perirenal fat invasion; 12) vessels; 13) Gerota's fascia; 14) lymph nodes; and 15) local and/or distant metastases. Results: Of the 63 tumors, 2 were complicated cysts; of the 61 remaining tumors, 10 were angiomyolipomas, 1 was a renal lymphoma, 1 was a focal xantogranulomatose pyelonephritis, 1 was a metanephric adenoma, 3 papillary renal cell carcinoma (RCC), 4 transitional cell tumors, 4 oncocytomas, 37 clear cell renal carcinoma. The CT could correctly characterize the 2 cystic tumors as such, as well as the 9 angiomyolipomas and the 4 transitional cell tumors. The 48 other tumors (1 angiomyolipoma, 1 lymphoma, 1 focal xantogranulomatose pyelonephritis, 1 metanephric adenoma, 3 papillary RCC, 4 oncocytomas, and 37 cell renal carcinomas) remaining were characterized as renal adenocarcinomas and CT staged. Conclusion: CT is a useful method to characterize renal masses since it determines their solid-cystic or fatty structure; aiding in many cases to define a surgical treatment. For the CT staging of renal tumors, the

    Full Text Available Nivolumab is a humanized IgG4 and programmed death 1 (PD-1 monoclonal antibody that has demonstrated antitumor efficacy in clinical trials of various malignant tumors including non-small-cell lung cancer and head and neck squamous cell carcinoma (SCC. However, patients with multiple primary malignancies were excluded in clinical trials. Thus, the efficacy of nivolumab in such patients has not been revealed yet. The programmed death ligand 1 (PD-L1 expression level is currently the main predictive biomarker of PD-1 inhibitors in various types of solid tumors and hematological malignancies. Here we describe a patient with synchronous double primary carcinomas of hypopharyngeal SCC and lung adenocarcinoma who exhibited different responses to nivolumab. After nivolumab treatment, hypopharyngeal SCC with moderate PD-L1 positivity by immunohistochemical staining showed a remarkable response; conversely, nivolumab was not effective against lung adenocarcinoma, which was negative for PD-L1. This suggests that tumors with different PD-L1 expressions may exhibit different responses to PD-1 inhibitors when multiple primary malignancies are present within one patient.

  20. CD117 expression in fibroblasts-like stromal cells indicates unfavorable clinical outcomes in ovarian carcinoma patients.

    Ruixia Huang

    Full Text Available The stem cell factor (SCF receptor CD117 (c-kit, is widely used for identification of hematopoietic stem cells and cancer stem cells. Moreover, CD117 expression in carcinoma cells indicates a poor prognosis in a variety of cancers. However the potential expression in tumor microenvironment and the biological and clinical impact are currently not reported. The expression of CD117 was immunohistochemically evaluated in a serial of 242 epithelial ovarian cancer (EOC cases. Thirty-eight out of 242 cases were CD117 positive in fibroblast-like stromal cells and 22 cases were positive in EOC cells. Four cases were both positive in fibroblast-like stromal cells and EOC cells for CD117. CD117 expression in fibroblast-like stromal cells in ovarian carcinoma was closely linked to advanced FIGO stage, poor differentiation grade and histological subtype (p<0.05, and it was significantly associated with poor overall survival (OS and progression free survival (PFS (Kaplan-Meier analysis; p<0.05, log-rank test. CD117 expression in ovarian carcinoma cells was not associated with these clinicopathological variables. The CD117 positive fibroblast-like stromal cells were all positive for mesenchymal stem/stromal cell (MSC marker CD73 but negative for fibroblast markers fibroblast activation protein (FAP and α smooth muscle actin (α-SMA, indicating that the CD117+/CD73+ fibroblast-like stromal cells are a subtype of mesenchymal stem cells in tumor stroma, although further characterization of these cells are needed. It is concluded herewith that the presence of CD117+/CD73+ fibroblast-like stromal cells in ovarian carcinoma is an unfavorable clinical outcome indication.

    2008-01-01

    Purpose: To investigate the value of Foxo3a in predicting the response to neoadjuvant treatment of, and prognosis for, esophageal squamous cell carcinoma. Methods and Materials: Immunohistochemical staining was performed in a retrospective series of 60 biopsied esophageal squamous cell carcinomas, and the correlation between nuclear accumulation of Foxo3a and clinicopathologic features was analyzed, including patient survival. In addition, in vitro biologic changes, radiosensitivity, and in vivo tumorigenicity of esophageal carcinoma cells after experimental manipulation of Foxo3a expression levels were determined. Results: Clinical findings point to a significant correlation between the nuclear accumulation of Foxo3a and the survival rate of esophageal cancer patients. In addition, Foxo3a is a significant predictor for the response to neoadjuvant therapy. In cell culture, irradiation and oxidative stress seemed to result in nuclear accumulation of Foxo3a. Down-regulation of Foxo3a significantly decreased radiosensitivity but had no obvious effect on tumor growth, as measured by a clonogenic assay in vitro and growth delay in vivo. Conclusions: Nuclear accumulation of Foxo3a in tumor cells was correlated with increased radiosensitivity and with improved patient survival. Thus, it is suggested that Foxo3a may be a potential marker for esophageal cancer

    2015-01-01

    Squamous cell carcinoma (SCC) arising from the wall of an odontogenic cyst (also known as primary intraosseous carcinoma) is a rare tumor which occurs only in jaw bones. This tumor was first described by Loos in 1913 as a central epidermoid carcinoma of the jaw. Primary intraosseous carcinomas (PIOC) may theoretically arise from the lining of an odontogenic cyst or de novo from presumed odontogenic cell rests. According to the new histological classification of tumors of the World Health Organization, odontogenic keratocyst is nowadays considered a specific odontogenic tumor and the PIOC derived from it is considered as a specific entity which is different from other PIOCs derived from the odontogenic cysts. The following report describes a case of such extremely rare entity that is primary intraosseous SCC of the mandible derived from an OKC in a 60-year-old male patient with brief review of literature.

    2017-01-01

    Full Text Available Solid organ transplant recipients are at high risk of developing malignancies due to the prolonged use of immunosuppressant drugs. Squamous cell carcinoma of skin can occur in these patients even after decades of organ transplant. A 45-year-old male underwent renal transplant for end-stage renal disease 23 years ago and was on immunosuppressive drugs since then. The patient was on regular follow-up. Three years back, he developed squamous cell carcinoma of both forearms and hands, which was treated with radiation therapy using 8 MeV electrons, by parallel opposed fields to a dose of 60 Gy/30 fractions. Complete response to treatment was achieved at 3 months posttreatment. The patient is currently on follow-up and asymptomatic for skin lesions. Hence, these patients require longer follow-up, active surveillance, and screening for early diagnosis and prompt treatment of the premalignant and malignant conditions.

O objetivo é avaliar o seguimento desses doentes para verificar as recidivas e a evolução do NIAA para câncer. Apresentação da casuística da Equipe Técnica de Proctologia do Instituto de Infectologia Emílio Ribas, de São Paulo. MÉTODOS: Acompanhamos 45 doentes HIV-positivos portadores de carcinoma espinocelular anal e seu precursor no período de 1996 a 2006. Eram 30 neoplasias intra-epiteliais anais de alto grau (NIAA, tratadas com ressecção local e 15 carcinomas invasores do canal anal. Nove das 15 lesões invasivas foram submetidas ao esquema de Nigro isolado ou associado à ressecção local, amputação abdominoperineal ou colostomia para derivação. RESULTADOS: No seguimento ambulatorial das NIAA tivemos recidiva em 16,7% e não observamos evolução para carcinoma, num período mínimo de três anos. Entre os nove tumores submetidos ao esquema de Nigro, com ou sem operação complementar, cinco estão livres de tumor. Nenhum tratamento foi feito em cinco doentes. Em três, devido às péssimas condições clínicas, e em dois, pois recusaram tratamento. Outro teve diagnóstico na vigência de oclusão intestinal sendo submetido à colostomia de derivação. CONCLUSÃO: Concluímos que a NIAA pode reincidir após excisão local em doentes HIV-positivos, mas não evolui para carcinoma invasor e que os doentes de câncer anal invasor podem ser tratados da mesma maneira que a população soronegativa para o HIV desde que as condições clínicas o permitam.OBJECTIVE: Incidence of anal squamous cell carcinoma is increasing mainly among HIV-positive patients.

    Abstract In carcinoma, such as of the lung, the histological subtype is important to select an appropriate therapeutic strategy for patients. However, carcinomas with poor differentiation cannot always be distinguished on the basis of morphology alone nor on clinical findings. Hence, delineation of poorly differentiated adenocarcinoma and squamous cell carcinoma, the 2 most common epithelial-origin carcinomas, is pivotal for selection of optimum therapy. Herein, we explored the potential utility of trefoil factor 3 (TFF3) as a biomarker for primary lung adenocarcinoma and extrapulmonary adenocarcinomas derived from different organs. We observed that 90.9% of lung adenocarcinomas were TFF3-positive, whereas no expression of TFF3 was observed in squamous cell carcinomas. The subtype of lung carcinoma was confirmed by four established biomarkers, cytokeratin 7 and thyroid transcription factor 1 for adenocarcinoma and P63 and cytokeratin 5/6 for squamous cell carcinoma. Furthermore, expression of TFF3 mRNA was observed by quantitative PCR in all of 11 human lung adenocarcinoma cell lines and highly correlated with markers of the adenocarcinomatous lineage. In contrast, little or no expression of TFF3 was observed in 4 lung squamous cell carcinoma cell lines. By use of forced expression, or siRNA-mediated depletion of TFF3, we determined that TFF3 appeared to maintain rather than promote glandular differentiation of lung carcinoma cells. In addition, TFF3 expression was also determined in adenocarcinomas from colorectum, stomach, cervix, esophagus, and larynx. Among all these extrapulmonary carcinomas, 93.7% of adenocarcinomas exhibited TFF3 positivity, whereas only 2.9% of squamous cell carcinomas were TFF3-positive. Totally, 92.9% of both pulmonary and extrapulmonary adenocarcinomas exhibited TFF3 positivity, whereas only 1.5% of squamous cell carcinomas were TFF3-positive. In conclusion, TFF3 is preferentially expressed in adenocarcinoma and may function as an

    Squamous cell carcinomas are malignant tumours of epithelial origin that can appear on sites subjected to chronic inflammation after a period of several years. The rapid development of squamous cell carcinoma at the donor site for a thin skin graft is a rare and poorly understood situation. We report the case of a patient undergoing thin skin grafting to cover the area of removal of a vertex squamous cell carcinoma and in whom squamous cell carcinoma appeared at the donor site within 9 weeks. In our case, we ruled out intraoperative contamination because two sets of surgical instruments were used. Given the number of cases reported in the literature, a chance event seems unlikely. The hypothesis of an acute inflammatory process caused by scarring of the thin skin graft site appears to us the most convincing. Development of cancer at the graft donor site may thus be added to the list of complications of thin skin grafting. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Treatment for metastatic cutaneous head and neck squamous cell carcinoma is usually multimodal and associated with morbidity. This study aimed to evaluate the impact of treatment on patients' quality of life. Cross-sectional survey of 42 patients (35 men, 7 women) at least 6 months after metastatic cutaneous head and neck squamous cell carcinoma treatment, using two standardised quality of life questionnaires: the Functional Assessment of Cancer Therapy - Head and Neck questionnaire and the Facial Disability Index, with statistical analysis to identify potential predictors of outcome. Female gender correlated with significantly lower Facial Disability Index physical function scores (p = 0.017). Alcohol consumption correlated with significantly better scores for Functional Assessment social well-being (p = 0.016), general total score (p = 0.041) and overall total score (p = 0.033), and for Facial Disability Index physical function (p = 0.034). Marital status, education, employment, chemotherapy, time from last treatment, parotidectomy and facial nerve sacrifice did not affect quality of life. The commonest patient complaints were dry mouth (76 per cent), altered voice quality and strength (55 per cent), and physical appearance (45 per cent). Female gender predicts worse quality of life, while alcohol consumption (versus none) predicted for better quality of life.

    Background Podoplanin expression is attracting interest as a marker for cancer diagnosis and prognosis. We therefore investigated the expression pattern and clinical significance of podoplanin during the development and progression of laryngeal carcinomas. Results Podoplanin expression was determined by immunohistochemistry in paraffin-embedded tissue specimens from 84 patients with laryngeal premalignancies and 53 patients with laryngeal squamous cell carcinomas. We found podoplanin expression extending from the basal to the suprabasal layer of the epithelium in 37 (44%) of 84 dysplastic lesions, whereas normal epithelium showed negligible expression. Patients carrying podoplanin-positive lesions had a higher laryngeal cancer incidence than those with negative expression reaching borderline statistical significance (51% versus 30%, P = 0.071). Podoplanin expression in laryngeal carcinomas exhibited two distinct patterns. 20 (38%) cases showed diffuse expression in most tumour cells and 33 (62%) focal expression at the proliferating periphery of tumour nests. High podoplanin expression was inversely correlated with T classification (P = 0.033), disease stage (P = 0.006), and pathological grade (P = 0.04). There was a trend, although not significant, towards reduced disease-specific survival for patients with low podoplanin levels (P = 0.31) and diffuse expression pattern (P = 0.08). Conclusions Podoplanin expression increases in the early stages of laryngeal tumourigenesis and it seems to be associated with a higher laryngeal cancer risk. Podoplanin expression in laryngeal squamous cell carcinomas, however, diminishes during tumour progression. Taken together, these data support a role for podoplanin expression in the initiation but not in the progression of laryngeal cancers. PMID:20196862

    Renal cell carcinoma is rarely seen in children and adolescents. Patients with widespread disease at diagnosis have a particularly poor survival rate. Currently, all known chemotherapy has been ineffective in improving the median survival in patients with advanced disease. A 13-year-old black boy with stage IV renal cell carcinoma with rhabdoid features is a long-term disease-free survivor after aggressive multiagent chemotherapy. After the initial evaluation and histologic diagnosis of renal cell carcinoma, the patient received three courses of an aggressive chemotherapy regimen consisting of vincristine, doxorubicin, cyclophosphamide with mesna uroprotection, granulocyte colony-stimulating factor and erythropoietin (Epogen). After an almost complete response, a radical nephrectomy was performed and results demonstrated a solitary small nodule with viable tumor. After surgery, he received floxuridine infusion for 14 days by circadian schedule at 28-day intervals for a total of 1 year. The patient is well and free of disease 5 years after initial presentation. The dramatic response to treatment and long-term disease-free survival of this patient suggest this chemotherapeutic approach warrants additional investigation.

    Between 1969 and 1985, 30 patients with carcinomas of the eyelid were treated by radiation, including 19 primary cases and 11 secondary cases. The latter were less controlable than the former. According to histology, there were 21 squamous cell carcinomas, 6 basal cell carcinomas and 3 adenocarcinomas. Among the 21 patients with squamous cell carcinomas, 5 had local recurrences, 10 had lymph node metastasis and 3 had distant metastasis. Patients with other histological classifications had no local recurrences, except for one who received incomplete therapy due to diabetes. Almost all of the controlled patients with squamous cell carcinomas were treated with a TDF value greater than 90. Although the visual function was damaged by irradiation in seven patients, the lesions of 6 of them were too advanced to avoid radiation injuries. (author)

    Primary squamous cell carcinomas of the thyroid gland are extremely rare, comprising about 1% of thyroid malignancies. Although squamous cell carcinomas are readily identified as such on aspiration cytology in the majority of cases, the differentiation of primary versus metastatic tumour might not always be easy. Herein, we report three cases of squamous cell carcinomas involving the thyroid gland. Fine needle aspiration cytology (FNAC) was performed in three patients with a thyroid mass using standard guidelines. Smears were stained with Diff-Quik and Papanicolaou stains. Two patients were male and one was female, aged 59, 45 and 35 years, respectively. In all three patients a thyroid mass was present. FNAC smears in all cases showed cytological features of squamous cell carcinoma including keratinization and necrosis. After clinical and cytological correlation, one case appeared to be primary, one case metastatic, and in the third case no additional clinical information or biopsy follow-up was available for further characterization. Because primary squamous cell carcinoma of the thyroid is a rare finding, metastatic squamous cell carcinoma should always be excluded first. Metastatic disease usually presents in the setting of widespread malignancy, therefore a dedicated clinical and radiological investigation is necessary in these cases. In both clinical scenarios the patient's prognosis is poor. © 2010 Blackwell Publishing Ltd.

    The aim of this study was to evaluate the disease outcomes of patients treated with definitive and adjuvant radiotherapy for squamous cell carcinomas of the nasal cavity and paranasal sinuses in a single institution. Between 2007–2012 patients were retrospectively identified from electronic databases who had undergone surgery and adjuvant radiotherapy or definitive radiotherapy for sinonasal squamous cell carcinomas with curative intent. Fourty three patients with sinonasal squamous cell carcinoma were identified (22 nasal cavity, 21 paranasal sinuses). 31/43 (72 %) had T3 or T4 disease; nodal stage was N0 in 38, N1 in 4, Na/b in 0 and N2c in 1 patient. Median age was 67 years (range 41–86). 18 (42 %) received definitive and 25 (58 %) adjuvant radiotherapy. Radiotherapy was delivered using either conventional radiotherapy (n = 39) or intensity modulated radiotherapy (n = 4). Elective neck radiotherapy was delivered to two patients. Chemotherapy was delivered to 6/43 (14 %) of patients. Two-year local control, regional control, distant metastases free survival, progression free survival, cause specific survival and overall survival were 81 %, 90 %, 95 %, 71 %, 84 % and 80 % respectively. There was no significant difference in outcome comparing patients who underwent surgery and adjuvant radiotherapy with patients receiving definitive radiotherapy (2 year locoregional disease free survival 75 % and 70 % respectively, p = 0.98). Pooly differentiated tumours were significantly associated with inferior disease outcomes. Local, regional, combined local and regional, and distant failure occurred in 7 (16 %), 3 (7 %), 1 (2 %) and 2 (5 %) of patients; all 3 regional recurrences were in patients with nasal cavity squamous cell carcinomas who had not undergone elective neck treatment. Definitive or adjuvant radiotherapy provides an effective treatment for sinonasal malignancies. The main pattern of failure remains local, suggesting the need for investigation of

    One of the risk factors for squamous cell oropharyngeal carcinoma is infection with the human papilloma virus (HPV), with prevalences that vary depending on the geographical region.  To identify the most frequent HPV viral types in oropharyngeal cancer, the levels of expression and the physical condition of the viral genome.  Forty-six patients were included in the study from among those attending head and neck surgical services in the cities of Bogotá, Manizales and Bucaramanga. In the histopathological report all study samples were characterized as oropharyngeal squamous cell carcinoma. DNA extraction was subsequently performed for HPV genotyping and to determine the physical state of the viral genome, as well as RNA to determine viral transcripts using real-time PCR.  HPV prevalence in tumors was 21.74% (n=10) and the most common viral type was HPV-16 (nine cases). Viral expression for HPV-16 was low (one of 11 copies) and the predominant physical state of the virus was mixed (eight cases), with disruption observed at the E1 - E2 binding site (2525 - 3720 nucleotides).  The prevalence of HPV associated with oropharyngeal carcinoma among the Colombian study population was 21.7%, which is relatively low. The most frequent viral type was HPV-16, found in a mixed form and with low expression of E7, possibly indicating a poor prognosis for these patients.

    To compare the clinicopathologic features and prognosis of Chinese patients with ovarian clear cell carcinoma (CCC) and serous carcinoma (SC). A retrospective cohort study was designed to investigate the clinicopathologic characteristic and prognosis of patients with CCC and SC who were diagnosed and treated in in a tertiary referral center (Peking Union Medical College Hospital) between 1999 and 2009. The Kaplan-Meier method and Cox regression were employed in the survival analysis. A total of 504 cases were included in the study, comprising 197 cases of CCC and 307 cases of SC. The mean age of the patients with SC was greater than of CCC patients (3.6±0.94, PPatients with CCC were more likely to be early-stage and optimally debulked (Ppatients with CCC had normal values, and the level was significantly lower than in patients with SC (Ppatients had platinum-resistant tumors compared with platinum-sensitive disease (45.7% in CCC vs. 61.0% in SC [P=0.008]). The 5-year survival rate was 51.2% in the CCC group vs. 49.8% in the SC group (P=0.428). Patients with advanced CCC had a statistically significant poorer overall survival (OS) compared with their SC counterparts (38.0 vs. 52.0 months; hazard ratio 1.584, 95% confidence interval [CI] 1.167-2.150, P=0.003). However, the advantage of improved progression-free survival (PFS) existed across all stages. Women with ovarian CCC presented at a younger age and early stage. Patients with ovarian CCC also had improved PFS, but they had similar OS compared to patients with SC. However, patients with advanced CCC had decreased survival.

This case series was carried out in the Department of Ophthalmology Civil Hospital and, Dow University of Health Sciences, Karachi and were reviewed from June 2004 to December 2007. Socio-demographic data and clinical features of patients with biopsy proven conjunctival squamous cell carcinoma were recorded and analysed. All patients underwent complete ophthalmic examination by a fellow ophthalmologist and clinical findings were recorded on a prescribed Performa. Data was analysed in terms of frequency, means and median by SPSS for windows V.15. Seventy-two percent of the patients were male and 28% were female, more than 80% of patients were in the age group of seventy years and above. Eighteen percent of patients developed intraocular invasion and the eyes had to be enucleated. CSCC occurs in sun damaged ocular surface usually at limbus, elderly men are more commonly involve, recurrence is a feature of disease and high risk in older individual. In our treatment we used various therapies, excision with clear margin, topical mitomycin C adjunctive cryotherapy and amniotic graft. (author)

    Xeroderma pigmentosum is a rare autosomal recessive genetic disease. This disease predisposes patients to early-onset skin cancers, particularly squamous cell carcinoma. Here, we report 3 pediatric cases, including 2 deaths. The subjects included 2 boys and 1 girl with skin type VI. All subjects were from consanguineous marriages, and the average age was 7.6 years. The patients all had ulcerative budding tumor lesions in the cephalic region, and the mean disease duration was 18 months. In all 3 cases, the diagnosis of xeroderma pigmentosum was made before the poikilodermal appearance of sun-exposed areas and photophobia. Neurological-type mental retardation was noted in 1 case. Histology confirmed squamous cell carcinoma in all 3 cases. The evolutions were marked by the death of 2 children (cases 1 and 3). In one case, the outcome was favorable following cancer excision and subsequent chemotherapy with adjuvant radiotherapy. Squamous cell carcinoma is a serious complication related to xeroderma pigmentosum in Sub-Saharan Africa. Prevention is based on the early diagnosis of xeroderma pigmentosum, black skin photoprotection, screening and early treatment of lesions, and genetic counseling.

    To investigate the association between oral hygiene, chronic diseases, and oral squamous cell carcinoma. We performed a case-control study with 414 cases and 870 controls in Fujian during September 2010 to January 2015. Patients were newly diagnosed oral squamous cell carcinoma cases according to the pathologic diagnoses, control subjects were enrolled from community population. Epidemiological data were collected by in-person interviews using a standard questionnaire. The contents of the questionnaire included demography character, history of tobacco smoking and alcohol drinking, dietary habits, oral hygiene status, family history of cancer, etc. Using unconditional logistic regression analysis to estimate adjusted odds ratios (OR) and corresponding 95% confidence intervals (CI) for oral hygiene and chronic diseases. We also stratified by sex, smoking and drinking to explore possible difference in association between subgroups. The multivariate logistic regression analysis indicated that number of teeth (20-27 and oral ulceration were the risk factors of oral squamous cell carcinoma, the adjusted OR (95% CI) values were 2.01 (1.49-2.73), 3.51 (2.39-5.15), 2.33 (1.79-3.04), 3.96 (2.11-7.44), respectively; brushing tooth once per bay, brushing tooth more than once per day, regular oral health examination at least 5 years per time were the protective factors of oral squamous cell carcinoma, the adjusted OR (95% CI) values were 0.24 (0.13-0.43), 0.13 (0.07-0.24), 0.37 (0.26-0.53), respectively. The stratification analysis indicated that recurrent oral ulceration could increase the risk of oral squamous cell carcinoma for non-smokers and non-drinking, the adjusted OR (95% CI) value was 5.21 (2.42-11.18) and 4.71 (2.37-9.36); and a risky effect of hypertension on risk of oral squamous cell carcinoma was observed for non-smokers and non-drinking, the adjusted OR (95% CI) values were 1.70 (1.10-2.61) and 1.58 (1.07-2.34). Oral hygiene and chronic diseases could affect the

    Changes in genomic DNA methylation associated with cancer include global DNA hypomethylation and gene-specific hyper- or hypomethylation. We have previously identified a genetic variant in the MTHFR gene involved in the methylation pathway which confers risk for the development of squamous cell carcinoma (SCC) in renal transplant patients. This genetic variant has also been discovered to confer SCC risk in nontransplant patients with low folate status.

    Cutaneous neuroendocrine (Merkel cell) carcinoma most often arises de novo in the background of a clonally integrated virus, the Merkel cell polyomavirus, and is notable for positive expression of retinoblastoma 1 (RB1) protein and low expression of p53 compared with the rare Merkel cell polyomavirus-negative Merkel cell carcinomas. Combined squamous and Merkel cell tumors are consistently negative for Merkel cell polyomavirus. Little is known about their immunophenotypic or molecular profile. Herein, we studied 10 combined cutaneous squamous cell and neuroendocrine carcinomas for immunohistochemical expression of p53, retinoblastoma 1 protein, neurofilament, p63, and cytokeratin 20 (CK20). We compared mutation profiles of five combined Merkel cell carcinomas and seven 'pure' Merkel cell carcinomas using targeted next-generation sequencing. Combined tumors were from the head, trunk, and leg of Caucasian males and one female aged 52-89. All cases were highly p53- and p63-positive and neurofilament-negative in the squamous component, whereas RB1-negative in both components. Eight out of 10 were p53-positive, 3/10 p63-positive, and 3/10 focally neurofilament-positive in the neuroendocrine component. Six out of 10 were CK20-positive in any part. By next-generation sequencing, combined tumors were highly mutated, with an average of 48 mutations per megabase compared with pure tumors, which showed 1.25 mutations per megabase. RB1 and p53 mutations were identified in all five combined tumors. Combined tumors represent an immunophenotypically and genetically distinct variant of primary cutaneous neuroendocrine carcinomas, notable for a highly mutated genetic profile, significant p53 expression and/or mutation, absent RB1 expression in the context of increased RB1 mutation, and minimal neurofilament expression.

    The combination of an immune checkpoint inhibitor and a VEGF pathway inhibitor to treat patients with advanced renal-cell carcinoma might increase the clinical benefit of these drugs compared with their use alone. Here, we report preliminary results for the combination of avelumab, an IgG1 monoclonal antibody against the programmed cell death protein ligand PD-L1, and axitinib, a VEGF receptor inhibitor approved for second-line treatment of advanced renal-cell carcinoma, in treatment-naive patients with advanced renal-cell carcinoma. The JAVELIN Renal 100 study is an ongoing open-label, multicentre, dose-finding, and dose-expansion, phase 1b study, done in 14 centres in the USA, UK, and Japan. Eligible patients were aged 18 years or older (≥20 years in Japan) and had histologically or cytologically confirmed advanced renal-cell carcinoma with clear-cell component, life expectancy of at least 3 months, an Eastern Cooperative Oncology Group performance status of 1 or less, received no previous systemic treatment for advanced renal cell carcinoma, and had a resected primary tumour. Patients enrolled into the dose-finding phase received 5 mg axitinib orally twice daily for 7 days, followed by combination therapy with 10 mg/kg avelumab intravenously every 2 weeks and 5 mg axitinib orally twice daily. Based on the pharmacokinetic data from the dose-finding phase, ten additional patients were enrolled into the dose-expansion phase and assigned to this regimen. The other patients in the dose-expansion phase started taking combination therapy directly. The primary endpoint was dose-limiting toxicities in the first 4 weeks (two cycles) of treatment with avelumab plus axitinib. Safety and antitumour activity analyses were done in all patients who received at least one dose of avelumab or axitinib. This trial is registered with ClinicalTrials.gov, number NCT02493751. Between Oct 30, 2015, and Sept 30, 2016, we enrolled six patients into the dose-finding phase and 49 into the

    Full Text Available High-grade neuroendocrine carcinoma of the urinary bladder comprehends small-cell and large-cell variants. It is a rare and aggressive neoplasm, mostly diagnosed in advanced stages. It is more frequently encountered among Caucasian men in the sixth decade of life. Urinary symptoms are the most common clinical presentation. Diagnosis is generally not troublesome once the lesions are easily detectable by imaging exams and cystoscopy. This neoplasia is associated with tobacco smoking, and is frequently associated with other carcinomatous components such as urothelial carcinoma, adenocarcinoma, and sarcomatoid carcinoma. The authors report a case of an apparently healthy female patient who presented cervical lymph node enlargement not accompanied by systemic symptoms. The supraclavicular lymph node biopsy revealed metastatic small cell carcinoma. The computed tomography scan showed a bladder wall nodular thickening, enlarged lymph nodes along the iliac, periaortic, mediastinal, cervical and supraclavicular chains, as well as an insufflating lytic bone lesion in the right iliac wing. The positron emission tomography-fluorodeoxyglucose (PET-FDG added to these findings, the presence of a paraesophageal lymph node, lymphadenomegaly in the gluteal region and a vertebral lytic lesion in T10. Resected specimen of the bladder tumor revealed a high-grade neuroendocrine carcinoma with small-cell and large-cell features.

    Full Text Available INTRODUCTION: Basal cell carcinoma is the most common tumor of the eyelid. In this region, reconstruction is complex and damage to healthy tissue should be minimal. Objective: To define the relationship between margin clearance at excision and the recurrence rate of basal cell carcinoma of the eyelid. METHODS: This prospective study was conducted with 111 patients submitted to surgery for basal cell carcinoma of the eyelid between 2001 and 2003 and followed up for a period of five years. The patients were evaluated according to age, tumor site, recurrence rate and margin clearance at excision. RESULTS: No significant association was found between incomplete tumor excision and recurrence except in patients under 56 years of age, female patients and in the case of tumors of the medial canthus. CONCLUSION: A risk of recurrence in incompletely excised basal cell carcinomas of the eyelid was only confirmed in younger patients, females and for tumors of the medial canthus.INTRODUÇÃO: O carcinoma basocelular é o tumor mais comum entre os tumores das pálpebras.

    Full Text Available Cancer has become a first order health problem worldwide, despite the great diagnostic and therapeutic programs achieved during the last years. This is a clinical case of an 81- year-old patient with personal and social history of promiscuous and unprotected sexual behavior that shows a vegetative lesion in his gland and numerous inguinal adenopathies. Biopsy confirms the diagnosis of squamous cell carcinoma infiltrating the penis, which is a relatively rare pathology which is generally diagnosed belatedly. Partial amputation of the penis was considered to be performed, but there was no consent on behalf of his family. The patient’s general condition was getting worse until he died.

    Full Text Available The EGFR-specific mAb cetuximab is one of the most effective treatments for oropharyngeal carcinoma, while patient responses to EGFR inhibitors given alone are modest. Combination treatment with radiation can improve the efficacy of treatment through increasing radiosensitivity, while resistance to radiation after administration of cetuximab limits its efficiency. Radiation and drugs can damage the endoplasmic reticulum (ER homeostatic state and result in ER stress (ERS, subsequently causing resistance to radiation and drugs. Whether the ERS pathway is involved in radioresistance after administration of cetuximab has not been reported. Herein, we show that cetuximab could increase the radiosensitivity of FaDu cells but not Detroit562 cells. In addition, cetuximab inhibited the radiation-induced activation of the ERS signalling pathway IRE1α/ATF6-GRP78 in FaDu cells, while this effect was absent in Detroit562 cells. Silencing GRP78 increased the radiosensitivity of oropharyngeal carcinoma cells and inhibited radiation-induced DNA double-strand-break (DSB repair and autophagy. More interestingly, silencing GRP78 abrogated resistance to cetuximab and radiation in Detroit562 cells and had a synergistic effect with cetuximab in increasing the radiosensitivity of FaDu cells. Immunohistochemistry showed that overexpression of both GRP78 and EGFR was associated with a poor prognosis in oropharyngeal carcinoma patients (P<0.05. Overall, the results of this study show that radioresistance after EGFR inhibition by cetuximab is mediated by the ERS signalling pathway IRE1α/ATF6-GRP78. This suppression was consequently unable to inhibit radiation-induced DSB repair and autophagy in oropharyngeal carcinoma cells, which conferred resistance to radiotherapy and cetuximab. These results suggest that the cooperative effects of radiotherapy and cetuximab could be further improved by inhibiting GRP78 in non-responsive oropharyngeal carcinoma patients.

    To investigate the status and treatment of superficial pharyngeal squamous cell carcinoma in Japan. We analyzed all cases diagnosed between 2011 and 2013, as recorded in the national database of hospital-based cancer registries. We extracted data on patient sex, age, tumor locations, histology, presentation routes, initial treatments, and TNM stages. Additionally, we compared the characteristics of pharyngeal carcinoma to those of esophageal cancer. A total of 16,521 oropharyngeal and hypopharyngeal cancers from 409 institutions were included. Diagnosis of Tis tumors was infrequent, and both cancers were likely to be diagnosed at an advanced stage (n = 866, 5.3%). Tis diseases were the most commonly detected during follow-up examinations for other diseases (n = 608, 70%). While more oropharyngeal Tis patients were men compared to T1-4 patients (88 vs 82%, respectively), hypopharyngeal cancer patients comprised an equally high proportion of men (94 vs 92%, respectively). The most common location of oropharyngeal Tis tumors was the posterior wall (32%), whereas T1-4 tumors were most commonly found on the lateral wall (36%). In hypopharyngeal cancer, both Tis and T1-4 were most commonly located in the pyriform sinus (62%). The proportion of Tis tumors diagnosed at individual institutions showed a positive correlation with the number of endoscopic treatments (r = 0.32, P squamous cell carcinoma patients in Japan. Further improvements in early diagnosis and standardized treatments are warranted.

    Full Text Available Fanconi Anemia (FA is an autosomal recessive disease characterized by chromosome instability, cellular hypersensitivity to DNA cross-linking agents, and increased predisposition to malignancies. We describe here a 28 year-old female with FA and vaginal squamous cell carcinoma treated by radiation therapy alone. The patient developed arm phlebitis, pulmonary fungal infection, and severe rectal bleeding, followed by hypocalcaemia, hypokalemia, vaginal bacterial and fungal infection, with subsequent leg and arm phlebitis, perineal abscess, and sepsis. The patient died 12 weeks later.

    Gorlin-Goltz syndrome or nevoid basal cell carcinoma syndrome (NBCCS) comprises multiple basal cell carcinomas, keratocysts of the jaw, palmar/plantar pits, spine and rib anomalies, calcifications of the falx cerebri etc. The diagnosis is made according to clinical criteria (Kimonis Criteria) and genetic ones. We studied one family where father and then his sun resulted affected by each syndrome. Gorlin-Goltz syndrome is a rare disease diagnosed according to clinical criteria sometimes difficult to integrate. The family case we presented shows how you can get diagnosis even in older age and after numerous surgeries. Patients should be given special attention and therefore should be monitorized and need multidisciplinary treatments continued in time, even a trivial change of signs and symptoms may be an important indicator of a precipitating event which puts the patient's life under threat.

    Sunitinib, a vascular endothelial growth factor pathway inhibitor, is an effective treatment for metastatic renal-cell carcinoma. We sought to determine the efficacy and safety of sunitinib in patients with locoregional renal-cell carcinoma at high risk for tumor recurrence after nephrectomy. In this randomized, double-blind, phase 3 trial, we assigned 615 patients with locoregional, high-risk clear-cell renal-cell carcinoma to receive either sunitinib (50 mg per day) or placebo on a 4-weeks-on, 2-weeks-off schedule for 1 year or until disease recurrence, unacceptable toxicity, or consent withdrawal. The primary end point was disease-free survival, according to blinded independent central review. Secondary end points included investigator-assessed disease-free survival, overall survival, and safety. The median duration of disease-free survival was 6.8 years (95% confidence interval [CI], 5.8 to not reached) in the sunitinib group and 5.6 years (95% CI, 3.8 to 6.6) in the placebo group (hazard ratio, 0.76; 95% CI, 0.59 to 0.98; P=0.03). Overall survival data were not mature at the time of data cutoff. Dose reductions because of adverse events were more frequent in the sunitinib group than in the placebo group (34.3% vs. 2%), as were dose interruptions (46.4% vs. 13.2%) and discontinuations (28.1% vs. 5.6%). Grade 3 or 4 adverse events were more frequent in the sunitinib group (48.4% for grade 3 events and 12.1% for grade 4 events) than in the placebo group (15.8% and 3.6%, respectively). There was a similar incidence of serious adverse events in the two groups (21.9% for sunitinib vs. 17.1% for placebo); no deaths were attributed to toxic effects. Among patients with locoregional clear-cell renal-cell carcinoma at high risk for tumor recurrence after nephrectomy, the median duration of disease-free survival was significantly longer in the sunitinib group than in the placebo group, at a cost of a higher rate of toxic events.

    A rare but serious complication of endometriosis is the development of carcinoma, and clear cell and endometrioid carcinomas of the ovary are the two most common malignancies which arise from endometriosis. They are distinct diseases, characterized by unique morphologies, immunohistochemical profiles, and responses to treatment. However, both arise in endometriosis and can share common mutations. The overlapping mutational profiles of clear cell and endometrioid carcinomas suggest that their varied histologies may be due to a different cell of origin which gives rise to each type of cancer. Cochrane and colleagues address this question in a recent article in this journal. They show that a marker of ovarian clear cell carcinoma, cystathionine gamma lyase, is expressed in ciliated cells. Similarly, they show that markers of secretory cells (estrogen receptor and methylenetetrahydrofolate dehydrogenase 1) are expressed in ovarian endometrioid carcinoma. Taken together, they suggest that endometrioid and clear cell carcinomas arise from cells related to secretory and ciliated cells, respectively. We discuss Cochrane et al's work in the context of other efforts to determine the cell of origin of gynecological malignancies, with an emphasis on recent developments and challenges unique to the area. These limitations complicate our interpretation of tumor differentiation; does it reflect nature imposed by a specific cell of origin or nurture, by either mutation(s) or environment?

    to invasive carcinomas of the lung, i.e., in bronchial hyperplasia/metaplasia and atypical adenomatous hyperplasia. In the stages leading to pulmonary squamous cell carcinoma, expression is sustained in dysplasia, carcinoma in situ and invasive carcinomas, and this pertains to the normal presence of C4.4A...... in squamous epithelium. In pulmonary adenocarcinomas, a fraction of cases is positive for C4.4A, which is surprising, given the origin of these carcinomas from mucin-producing and not squamous epithelium. Interestingly, this correlates with a highly compromised patient survival and a predominant solid tumor...
