    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.

    The coexistence of two malignancies is rarely seen. A little association between hematologic malignancies especially multiple myeloma and renal cell carcinoma has been reported in the recent past. Several case series revealed a bidirectional association between these two malignancies which may be due to the common risk factors, similar cytokine growth requirements and clinical presentation. Here, we aim to describe a patient who had multiple myeloma and in his work up renal cell carcinoma was found out incidentally. We would like to create awareness among clinicians for the coincidence of Renal cell carcinoma and Multiple myeloma.

    Mutations in the PTCH gene, the human homolog of the Drosophila patched gene, have been found to lead to the autosomal dominant disorder termed Nevoid Basal Cell Carcinoma Syndrome (NBCCS, also called Gorlin Syndrome). Patients display an array of developmental anomalies and are prone to develop a variety of tumors, with multiple Basal Cell Carcinomas occurring frequently. We provide here the results of molecular testing of a set of Italian Nevoid Basal Cell Carcinoma Syndrome patients. Twelve familial patients belonging to 7 kindreds and 5 unaffected family members, 6 non-familial patients and an additional set of 7 patients with multiple Basal Cell Carcinoma but no other criteria for the disease were examined for mutations in the PTCH gene. All of the Nevoid Basal Cell Carcinoma Syndrome patients were found to carry variants of the PTCH gene. We detected nine novel mutations (1 of which occurring twice): 1 missense mutation (c.1436T>G [p.L479R]), 1 nonsense mutation (c.1138G>T [p.E380X]), 6 frameshift mutations (c.323_324ins2, c.2011_2012dup, c.2535_2536dup, c.2577_2583del, c.3000_3005del, c.3050_3051del), 1 novel splicing variant (c.6552A>T) and 3 mutations that have been previously reported (c.3168+5G>A, c.1526G>T [p.G509V], and c.3499G>A [p.G1167R]). None of the patients with multiple Basal Cell Carcinoma but no other criteria for the syndrome, carried germline coding region mutations.

    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.

    A 75-year-old-man, with a 2-month history of abdominal pain, underwent a standard diagnostic workup that included a CT scan that showed a large right renal mass and subcentimeter nodes in the right and left lung lobes. In December 2003, the patient underwent right nephrectomy with adrenalectomy and a diagnosis of renal cell carcinoma (pT3N0M0 stage) was made. No further treatment was proposed and patient was followed up regularly. In October 2006, the annual gastrointestinal endoscopy showed asymptomatic multilobulated and polypoid masses in the gastric fundus and gastric body that corresponded to metastasis of the renal carcinoma that had been resected three years ago. Surgical treatment was refused and oral treatment with sunitinib (50 mg/day consecutively for 4 weeks followed by 2 weeks off) was initiated. Patient completed one cycle and development of acute toxicity (grade 3 asthenia, anorexia and mucositis) led to treatment interruption. After recovering from acute toxicity, the patient was proposed to reinitiate treatment with dose reduction, but he refused any medical treatment. At the follow-up visit, three months later, the gastrointestinal endoscopy showed four unspecific 2 mm nodules without malignant evidence. The whole-body CT did not reveal any other abnormality except for the known lung nodes. PET scan six months after treatment confirmed complete gastric response.

    Objective. To evaluate the use of flexible esophagoscopy and chromoendoscopy with Lugol's solution in the detection of early esophageal carcinomas (second primary carcinomas) in patients with squamous cell carcinoma of the head and neck (HNSCC). Methods. All patients with newly diagnosed HNSCC underwent office-based Lugol's chromoendoscopy. After flexible esophagoscopy with white light, 3.0% Lugol's iodine solution was sprayed over the entire esophageal mucosa. Areas with less-intense staining (LVLs) were evaluated and biopsies taken. Results. 132 patients with HNSCC were enrolled in this study. The most frequent primary tumors were oropharyngeal (49/132), tumors of the oral cavity (36/132), and larynx (35/132). The majority of subjects (107/132 patients, 81.1%) had advanced HNSCC carcinomas (stages III and IV). Multiple LVLs were discovered in 24 subjects (18.2%) and no LVLs in 108 (81.8%) subjects. Fifty-five LVL biopsy specimens were obtained and assessed. Squamous cell carcinomas were detected in two patients, peptic esophagitis in 11 patients, gastric heterotopic mucosa in two patients, hyperplasia in two patients, and low- and high-grade dysplasia in three patients. Conclusion. Although only two patients with synchronous primary carcinomas were found among the patients, esophagoscopy should be recommended after detection of HNSCC to exclude secondary esophageal carcinoma or dysplasia.

    Mycobacteria cause a range of diseases in both immunocompetent and immunosuppressed individuals. An increase in non-tuberculous mycobacterial (NTM) infections targeting skin has been described. Many hypotheses have been developed in order to explain it: the increasing burden of immunocompromised individuals, immigration from endemic countries, improved laboratory identification techniques, and changes inhuman behavior that expose individuals to this NTM. Mycobacterium mucogenicum group comprises M. mucogenicum, Mycobacterium aubagnense, and Mycobacterium phocaicum. This group of organisms was first named Mycobacterium chelonae-like organism in 1982. Most clinically significant cases of those organisms involved catheter-related infections. Nevertheless, we report an interesting patient with a cutaneous infection produced by M. mucogenicum mimicking a squamous cell carcinoma; an excellent response to combined therapy with rifampicin and clarythromicin was observed.

    Full Text Available Bacground/Aim. Systemic candidiasis in intensive care units remains an improtant problem due to antifungal resistance. 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

    We evaluated dendritic cells (DC), regulatory T lymphocytes (Treg) and neutrophils in 37 patients with newly diagnosed renal cell carcinoma (RCC) in the tumor and peripheral blood (PB) and correlated these parameters with tumor staging (early-T1, 2, late-T3, 4 and metastatic disease). The number of myeloid and plasmacytoid DC in blood of RCC patients was higher than in healthy controls. The percentage of myeloid dendritic cells (mDC) from CD45+ cells in tumors was higher in comparison with peripheral blood irrespective of disease stage. Higher percentage of these cells expressed a maturation marker in the periphery in the early stage (CD83 expressing cells). The number of plasmacytoid dendritic cells (pDC) in PB was similar in both early and late stage groups, but the early group displayed a significantly higher percentage of pDC in tumor cell suspension. Neutrophil counts in the peripheral blood of RCC patients were higher than in healthy controls, but the counts in both tumor stage groups were similar. The proportion of neutrophils from CD45+ cells was higher in late stage tumors. Higher percentage of Treg from CD4+ cells was detected in renal carcinoma tissue in comparison to PB with no difference between stages of the disease. Our results reflect the complex interplay between various cells of the immune system and the tumor microenvironment. Activation of dendritic cell subpopulations at early stages of the disease course is counterbalanced by the early appearance of T regulatory cells both in the periphery and tumor tissue. Later stages are characterized by the accumulation of neutrophils in the tumor. Appropriate timing of anticancer strategies, especially immunotherapy, should take these dynamics of the immune response in RCC patients into account.

    Full Text Available Cytoreductive nephrectomy as an independent option in patients with metastatic renal cell carcinoma (mRCC cannot be considered as the only effective method, with rare exception, of a few patients with solitary metastases. Cytoreductive nephrectomy is now part of a multimodal approach encompassing surgical treatment and systemic drug therapy. Many retrospective and two prospective studies have demonstrated that it is expedient to perform cytoreductive nephrectomy. Immunotherapy should not be used as preoperatively in the era of cytokine therapy for mRCC due to that fact that it has no impact on primary tumor. In the current targeted therapy era, many investigators have concentrated attentionon the role of neoadjuvant targeted therapy for the treatment of patients with both localized and locally advanced mRCC. The potential benefits of neoadjuvant therapy for localized and locally advanced RCC include to make surgery easier and to increase the possibility of organsparing treatment, by decreasing the stage of primary tumor and the size of tumors. The possible potential advantages of neoadjuvant targeted therapy in patients with mRCC include prompt initiation of necessary systemic therapy; identification of patients with primary refractory tumors; and a preoperative reduction in the stage of primary tumor. Numerous retrospective and some prospective phase II studies have shown that neoadjuvant targeted therapy in patients with localized and locally advanced RCC is possible and tolerable and surgical treatment after neoadjuvant targeted therapy is safe and executable with a low incidence of complications. If neoadjuvant therapy is to be performed, it should be done within 2–4 months before surgery. Sorafenib and sunitinib are now most tested and suitable for neoadjuvant targeted therapy. Sorafenib is a more preferred drug due to its shorter half-life and accordingly to the possibility of discontinuing the drug immediately prior to

    Background & Aims 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). Methods 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). Results 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. Conclusions SART3 is an immunotherapeutic candidate, and peptides from this antigen may be applied in HCC immunotherapy. Trial Registration UMIN000005677 PMID:28114424

    2011-01-01

    Full Text Available 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.

    Objective: To analyze the clinical application of interleukin-2 therapy in patients with metastatic renal cell carcinoma.Methods:From January 2010 to July 2014 of 108 patients with metastatic renal cell carcinoma patients in our hospital as research subjects were randomly divided into the experimental group and the control group. The experimental group received IL-2 combined with Nexavar therapy, and the control group only received Nexavar treatment, clinical efficacy and incidence of adverse reactions between the two groups of patients were compared.Results:Compared with the control group, clinical efficacy in the experimental group was significantly higher, the difference was statistically significant. The incidence of adverse events was higher in patients than that in the experimental group, the difference was statistically significant, but IL-2 had no new adverse reactions and side effects.Conclusions:Interleukin-2 combined with Nexavar treatment of metastatic renal cell carcinoma can improve the clinical efficacy of metastatic renal cell carcinoma in patients, and ease the patient's condition from worsening and promote the quality of life. However, adverse reactions caused by drugs were inevitable; we should pay attention to treatment and prevention of adverse reactions in order to improve the quality of life of patients with metastatic renal cell carcinoma.

This report describes a rare left portal hypertension in a patient who presented with a dilated esophagogastric vein upon esophagogastroduodenoscopic examination of a gastric polyp. A contrast-enhanced computed tomography scan revealed a pancreatic tumor, with obstruction of the splenic vein and portal-systemic shunt. The patient was diagnosed with an acinar cell carcinoma of the pancreatic tail. This patient highlights that pancreatic acinar cell carcinoma should be considered as a differential diagnosis in patients with a dilated esophagogastric vein and without signs of liver disease.

    AIM: To investigate the immune function of dendritic cells from both peripheral blood and operated tissues of esophageal carcinoma patients in order to find the relationship between the immune function of dendritic cells and the pathogenesis of esophageal carcinoma.METHODS: The expression of CD83, CD80, and CD86 on the surface of dendritic cells cultured from the peripheral blood of patients was detected compared with that from health donors using flow cytometry. The ability of dendritic cells to induce T lymphocyte proliferation was evaluated by a liquid scintillation counter. The expression of CD80, CD86,CD83, and S-100 proteins was assessed in esophageal carcinoma tissues using immunohistochemical method.RESULTS: Compared with those from healthy donors,dendirtic cells cultured from the peripheral blood of patients expressed lower CD80 and CD86. Furthermore, the ability of dendritic cells in patients to induce T lymphocyte proliferation was significantly lower than that of the control group. Compared with the control group, the positive expression ratio and frequencies of CDS0, CD86, and S100 in esophageal carcinoma tissues were significantly down regulated. The expression of CD83 was up-regulated in the pericancerous tissues, but no expression was found in the cancerous nodules,CONCLUSION: The impaired immune function and the decreased number of dendritic cells cause pathogenesis and progression of esophageal carcinoma.

    The aim of this study was to describe pathologic features found at autopsy of 14 patients with penile cancer. Nine patients died from disseminated disease; 5 of them presented local/regional recurrences. Five patients died from other causes, 2 of them postoperatively. Local recurrence sites were corpus cavernosum, Buck's fascia and urethra, regional skin, and prostate. Metastatic sites were lymph nodes (9 cases), liver (7 cases), lungs (6 cases), heart (5 cases), adrenals, bone and skin (3 cases each), thyroid and brain (2 cases each), and pancreas, spleen, and pleura (1 case each). Patients with heart metastasis had arrhythmias. Patients who died and who did not die from penile cancer had different profiles: low-grade superficial tumors with usual and warty subtypes versus high-grade deeply invasive basaloid or hybrid verrucous/sarcomatoid carcinomas. A natural history model for penile cancer routes of spread is proposed: local intrapeneal, regional and systemic nodes, regional skin, liver, lungs, heart, and other multiple sites.

    2012-01-01

    Celiac disease is a gluten-related malabsorption in small intestine occurring in genetically susceptible patients. In this disease the risk of many malignancies is increased the most important of which being non-Hodgkin lymphoma of small intestine. Other malignancies include adenocarcinoma of small intestine and squamous cell carcinoma of esophagus and melanoma. As to our knowledge so far only one case of celiac disease associated with hypopharyngeal squamous cell carcinoma has been reported. In this article we presented a patient suffering from celiac disease with squamous cell carcinoma of hypopharynx. She underwent chemotherapy and radiation therapy, unfortunately however she died because of progress of disease. So, in patients with celiac disease we should pay attention to various malignancies and when cases of cancers are accompanied by malabsorption we must think of celiac disease involvement.

    The combination of renal cell carcinoma (RCC) and hepatocellular carcinoma (HCC) is extremely rare, and the prognosis for patients with these two cancers is poor. In the past decade, molecular targeted therapy and radiofrequency ablation (RFA) have emerged and these treatments are now playing an increasingly important role in the management of patients with advanced primary RCC and HCC. In this case report, a 72-year-old male patient diagnosed as having RCC invading the renal vein and grade I-II HCC was treated with RFA and sorafenib (400 mg twice daily). After 3 months of this combination treatment, an evaluation of his target lesions showed stable disease (SD), and progression-free survival (PFS) times were 28 months weeks for RCC and 16 months weeks for HCC. Overall survival (OS) was 40 weeks.

    Introduction The majority of cases of lung cancer are still diagnosed at a late stage. 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.

    Xp11 translocation renal cell carcinoma (RCC) is a relatively rare tumor mainly affecting children and adolescents. It shows significant morphological overlap with the 2 most common adult renal tumors, which are the clear cell (conventional) RCC and papillary RCC. We describe case of a young adult female who presented with right flank pain and abdominal mass. Radiological investigations showed features suggestive of renal cell carcinoma in the right kidney. Histopathological findings while suggestive of Xp11 carcinoma, showed significant overlap with the recently described entity clear cell papillary RCC. TFE3 immunohistochemistry confirmed the tumor to be Xp11 translocation RCC. The patient had an aggressive course with lymph node metastasis. In this report, we discuss differential diagnosis and the diagnostic challenges of Xp11 translocation RCC in adults.

    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.

    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

    Objective: To understand the relationship between the expression of ras and p53 and histological types, degree of differentiation, TNM classification, stage, and patients'prognoses of non-small-cell lung cancer, we examined Haras and p53 production in 143 non-small-cell lung carcinomas. Methods: One hundred and forty-three paraffin-embedded surgically resected specimens of primary non-small-cell lung carcinomas (57 squamous cell carcinomas, 63 acinar adenocarcinomas, 15 bronchioloalveolar carcinomas, and 8 large-cell carcinomas) were stained by streptavidin-peroxidase immunohistochemical method using anti-Ha-ras monoclonal and anti-p53monoclonal (DO-1) antibodies. Results: Ha-ras was found in 68% (87 of 143) of lung carcinomas. The positive rate of Ha-ras staining in well differentiated carcinoma was 89%,significantly higher than that in moderately differentiated carcinoma (66%, P<0.05) and that in poorly differentiated carcinoma (48%, P<0.01). The 5-year survival rates of patients whose tumors had no (39%, P<0.01) or moderate (33%, P<0.05) Ha-ras production were significantly higher than that of patients whose tumors had strong staining (14%) for Ha-ras. Sixty percent lung carcinomas (86 of 143)had p53 accumulation. Patients whose tumors did not express p53 survived, on average, significantly longer after tumor resection than did patients whose tumors expressed p53. With increasing p53 accumulation, the average length of survival after tumor resection significantly decreased.Conclusion: Ha-ras overproduction and p53 accumulation correlate with unfavorable prognoses of patients with nonsmall-cell lung carcinomas. Ha-ras production in non-smallcell lung carcinoma was related to the degree of differentiation.

    Full Text Available Abstract Background In the era of cytokines, patients with brain metastases (BM from renal cell carcinoma had a significantly shorter survival than patients without. Targeted agents (TA have improved the outcome of patients with metastatic renal cell carcinoma (mRCC however, their impact on patients with BM is less clear. The aim of this analysis was to compare the outcome of patients with and without BM in the era of targeted agents. Methods Data from 114 consecutive patients who had access to targeted agent were analyzed for response rates (ORR, progression free survival (PFS and overall survival (OS. All patients diagnosed with BM underwent local, BM-specific treatment before initiation of medical treatment. Results Data of 114 consecutive patients who had access to at least one type of targeted agents were analyzed. Twelve out of 114 renal cell carcinoma (RCC patients (10.5% were diagnosed with BM. Systemic treatment consisted of sunitinib, sorafenib, temsirolimus or bevacizumab. The median PFS was 8.7 months (95% CI 5.1 - 12.3 and 11.4 months (95% CI 8.7 - 14.1 for BM-patients and non-BM-patients, respectively (p = 0.232. The median overall survival for patients with and without BM was 13.4 (95% CI 1- 43.9 and 33.3 months (95% CI 18.6 - 47.0 (p = 0.358, respectively. No patient died from cerebral disease progression. ECOG Performance status and the time from primary tumor to metastases (TDM were independent risk factors for short survival (HR 2.74, p = 0.001; HR: 0.552, p = 0.034. Conclusions Although extracerebral metastases determine the outcome of patients with BM, the benefit from targeted agents still appears to be limited when compared to patients without BM.

    Full Text Available The aim of the present study was to examine the epidemiology, natural history, treatment and long-term survival of patients with adenosquamous cell carcinoma of the prostate. The Surveillance, Epidemiology, and End Results (SEER Program database was used to identify ASCC of prostate cases between January 1973 and December 2006. Survival probabilities were estimated using the Kaplan-Meier methods and compared using the log-rank test. A total of 25 patients with adenosquamous cell carcinoma of the prostate were identified during the study period. The median age was 74 years (range 53-98. Twenty percent of study subjects presented with metastatic disease. Among those patients with known grade (n=16, 75% had poorly or undifferentiated histology. A total of 40% of study subjects received radical prostatectomy, while 24% of the patients had primary radiation therapy. The 1-, 3-, and 5-year cancer specific survival rates for the entire cohort were 55.2%, 37.8%, and 30.3%, respectively. For patients who underwent prostatectomy, the 1-, 3-, and 5-year survival rates were 78%, 78%, and 63%, respectively. For the patients who did not receive prostatectomy, the 1-year survival rates were 38.7% and none survived to three years. Adenosquamous cell carcinoma is a rare aggressive subtype of prostate cancer with poor cancer specific survival. The development of new therapeutic approaches for this aggressive tumor is urgently needed.

    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.

    2012-07-01

    Vismodegib is a novel, small-molecule inhibitor of smoothened, a key component of the hedgehog signaling pathway. Increased hedgehog pathway signaling is critical in the development of hereditary and spontaneous basal cell carcinomas of the skin, and has been implicated in the development of a number of other tumors. In preclinical models, vismodegib demonstrated potent antitumor activity in hedgehog-dependent tumors, particularly basal cell carcinomas. Clinically, phase I and II studies showed dramatic anticancer activity in patients with advanced basal cell carcinomas. In January 2012, vismodegib was approved by the FDA for the treatment of unresectable or metastatic basal cell carcinomas of the skin.

  18. Telomere length in relation to immunological parameters in patients with renal cell carcinoma.

    Ulrika Svenson

    Full Text Available Over the last decade, telomere length (TL has gained attention as a potential biomarker in cancer disease. We previously reported that long blood TL was associated with a poorer outcome in patients with breast cancer and renal cell carcinoma. Based on these findings, we hypothesized that certain immunological components may have an impact on TL dynamics in cancer patients. One aim of the present study was to investigate a possible association between serum cytokines and TL of peripheral blood cells, tumors and corresponding kidney cortex, in patients with clear cell renal cell carcinoma. For this purpose, a multiplex cytokine assay was used. Correlation analysis revealed significant positive correlations between tumor TL and peripheral levels of three cytokines (IL-7, IL-8 and IL-10. In a parallel patient group with various kidney tumors, TL was investigated in whole blood and in immune cell subsets in relation to peripheral levels of regulatory T cells (Tregs. A significant positive association was found between whole blood TL and Treg levels. However, the strongest correlation was found between Tregs and TL of the T lymphocyte fraction. Thus, patients with higher Treg levels displayed longer T cell telomeres, which might reflect a suppressed immune system with fewer cell divisions and hence less telomere shortening. These results are in line with our earlier observation that long blood TL is an unfavorable prognostic factor for cancer-specific survival. In summary, we here show that immunological components are associated with TL in patients with renal cell carcinoma, providing further insight into the field of telomere biology in cancer.

    The significance of serum p53-Abs in patients with esophageal squamous cell carcinoma was determined. Examination of clinicopathological features and assessment of tumor marker sensitivities of carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCC-Ag) and CYFRA21-1 were performed. Thirty-three (58%) of 57 patients were positive for serum p53-Abs, however, no relation with cancer progression existed. Fourteen of the 33 sero-positive patients revealed normal levels of all tumor markers tested. Thus, serum p53-Abs appears to be a useful marker for the detection of esophageal squamous cell carcinoma.

    Despite the radical surgical resection performed in patients with colorectal carcinoma, there is a high rate of tumor recurrence. Over an observation period of 3 years, 18% of the patients in our collective suffered a tumor relapse with local or distinct metastases after initial R0-resection. Some evidence suggests that this may be due to suppression of anti-tumor responses, a phenomenon that might be attributed to regulatory T cells. The aim of our study was to investigate the tumor-specific immune response depending on the UICC stage of patients with colorectal cancer. The cellular immune responses against defined antigens that are overexpressed in most of the patients with colorectal cancer were characterized. For this purpose, the tumor suppressor gene, p53, was chosen as the tumor-associated antigen that exhibits mutations and overexpression in up to 60% of colorectal carcinoma. We observed that p53 induced both IFN-gamma and IL-10 secretion. The predominance of IL-10 production indicated that regulatory T cells directly participate in modulating the anti-tumor immune response. IL-10 levels in the blood as well as the expression of regulatory T-cell specific genes at the tumor site correlate with the UICC stage of the disease. These results may provide an explanation for the poor prognosis and increased recurrence rate in patients with advanced carcinoma.

    AIM: To investigate the expression of thymidylate synthase (TS) and glutathione-s-transferase π (GST-π) in esophageal squamous cell carcinoma and their association with the clinicopathologic characteristics. METHODS: Immunohistochemical methods were used to detect the expression of TS and GST-π in surgically resected formalin-fixed, paraffin-embedded esophageal squamous cell carcinoma (ESCC) tissue sections from 102 patients (median age, 58 years) and in 28 normal esophageal mucosa (NEM) samples. The relationship between TS and GST-π expression and clinicopathologic factors was examined. RESULTS: The expression of TS and GST-π was not statistically significantly associated with age of the patients, tumor size, lymph node metastasis, depth of invasion or tumor stage. TS staining was positive in 17.86% of normal esophageal mucosa and in 42.16% of ESCC samples (P < 0.05). The expression level of TS was not only significantly lower in well-differentiated (21.88%) than in poorly-differentiated carcinomas (51.43%, P < 0.05), but was also significantly higher in samples from male patients (46.51%) than from female patients (18.75%, P < 0.05). GST-π was positively stained in 78.57% of normal esophageal mucosa and in 53.92% of ESCC samples (P < 0.05). The expression level of GST-π was also significantly higher in welldifferentiated carcinomas (65.63%) than in poorlydifferentiated carcinomas (35.00%, P < 0.05). CONCLUSION: The expression of TS and of GST-π may be used as molecular markers for the characterization of ESCC. Poorly-differentiated cells showed increased expression of TS and reduced expression of GST-π.

    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

    Full Text Available Objective: to improve the results of treatment in patients with squamous cell carcinoma of the anal canal, by creating a new combination treatment option, and to increase the rate of organ-sparing treatment.Subjects and methods. A new combination treatment option for squamous cell carcinoma of the anal canal was created, which involved a combination of radiotherapy and a multiple radio modification program (ultrahigh-frequency (UHF hyperthermia and local metronidazole (MZ injection and systemic polychemotherapy (RF patent No. 2427399 “A treatment option for squamous cell carcinoma of the anal canal” registered on 27 August 2011. To evaluate the created treatment option, the latter was analyzed in 157 patients with Т1–4N0–3M0 squamous cell carcinoma of the anal canal, who had been treated in 1990 to 2012. In 22 patients, radiotherapy was performed in combination with 3–5 sessions of local UHF hyperthermia (thermoradiotherapy (TRT; 88 patients received the latter in combination with polychemotherapy (thermoradiochemotherapy (TRCT; in addition to TRCT, 47 patients used MZ (TRCT + MZ.Results. In the TRT, TRCT, and TRCT + MZ groups, organ-sparing treatment was performed in 11 (50 %, 71 (80.7 %, and 44 (93.6 % patients, respectively. In these groups, the median follow-up was 18.6; 51.7, and 15.5 months, respectively. In the 3 groups, the three-year overall survival rates were 71.4; 90.0, and 96.3 % and the three-year relapse free survival rates were 46.7; 60.6, and 75.0 %, respectively.Conclusion. The created combination thermochemoradiotherapy involving a polymer combination with MZ (TRCT + MZ makes it possible to achieve organ-sparing treatment in 93.6 % of the patients and to slightly improve 3-year overall and relapse-free survival rates in patients with squamous cell carcinoma of the anal canal who have received organ-sparing treatment although there is only a tendency for statistical survival difference in this patient group.

    Background Oral squamous cell carcinoma is an important cause of death and morbidity wordwide and effective prognostic markers are still to be discovered. HIF1α protein is associated with hypoxia response and neovascularization, essential conditions for solid tumors survival. The relationship between HIF1α expression, tumor progression and treatment response in head and neck cancer is still poorly understood. Patients and Methods In this study, we investigated HIF1α expression by immunohistochemistry in tissue microarrays and its relationship with clinical findings, histopathological results and survival of 66 patients with squamous cell carcinoma of the lower mouth. Results Our results demonstrated that high HIF1α expression is associated with local disease-free survival, independently from the choice of treatment. Furthermore, high expression of HIF1α in patients treated with postoperative radiotherapy was associated with survival, therefore being a novel prognostic marker in squamous cell carcinoma of the mouth. Additionally, our results showed that MVD was associated with HIF1α expression and local disease relapse. Conclusion These findings suggest that HIF1α expression can be used as a prognostic marker and predictor of postoperative radiotherapy response, helping the oncologist choose the best treatment for each patient.

    Objective: To explore the treatment of clinically negative neck (CN0) patients with squamous cell carcinoma of the tongue. Methods: 165 CN0 patients with squamous cell carcinoma of the tongue from 1985 to 2002 were investigated retrospectively. Parts of the patients staged at T1, T2 and T3 underwent resection of primary lesion followed by neck observation, and other patients staged above T2 or at T1 but without follow-up were treated with elective neck dissection (END). All patients were followed up for more than 3 y or until their death. Results: Lymphatic metastasis was identified histologically after operation in 33 of 120 patients treated with END, and 9 of 45 patients treated with resection of primary lesion alone. The overall rate of occult lymphatic metastasis was 25.45%, which increased with the elevating of clinical T stage. The overall rate of neck uncontrolled death was 20.00% for observation group and 5.00% for END group, and significant difference was found between them (P<0.05). For T1 patients in the two groups, the rate of neck uncontrolled death was 7.71% and 4.00% respectively, and no significance was found between them (P>0.05). When stage T2 and T3 were considered as middle stage together, significant difference (P<0.05) could be obtained between observation (70.00%) and END group (0%). Conclusion: The occult metastasis rate of squamous cell carcinoma of tongue increases with the elevating of clinical stage, and elective neck dissection could be considered for N0 patients staged over T2 to improve neck control and survival rate; and regional resection alone of primary lesion could be considered for T1N0 patients to improve quality of life if closely followed up is conducted.

    Renal cell carcinoma (RCC) accounts for approximately 3% of adult malignancies. For stage I - III RCC surgery is the primary treatment. Systemic therapy is used in the patients with disseminated disease (stage IV). Sunitinib malate is commonly used in the patients with clear cell renal cell carcinoma (ccRCC) rated as 'low' or 'intermediate' risk according to the Motzer scale. Treatment with sunitinib malate is associated with myelotoxicity. To assess its clinical significance we conducted a pilot study in a group of 10 patients. We noticed a gradual decrease in the mean haemoglobin level during subsequent treatment cycles. Alternations in the platelet count were of no clinical significance. Episodes of the neutropenia were noticed in the study group. In some patients neutrophil count decreased to the level that put them at risk of the infectious complications.

    AIM: To analyze the phenotype and function of dendritic cells (DC) from patients with hepatocellular carcinoma (HCC) in order to understand their role in this disease.METHODS: Myeloid dendritic cells were enumerated in peripheral blood of HCC patients. CD80, CD83, CD86 and HLA-DR expression on naive and stimulated myeloid dendritic cells from peripheral blood were analyzed. Myeloid dendritic cells were isolated from peripheral blood and their function was tested. Phagocytosis was analyzed using FITC-dextran beads, peptide specific stimulation, the capacity to stimulate allogeneic T cells and secretion of cytokines upon poly dI:dC was tested.RESULTS: Myeloid dendritic cells were reduced in patients with HCC. No differences in CD80, CD83, CD86 and HLA-DR expression were found on naive and stimulated myeloid dendritic cells from HCC patients and healthy controls. Normal phagocytosis or stimulation of peptide specific T cells was observed in contrast to an impaired allo-stimulatory capacity and a reduced IL-12 secretion.CONCLUSION: Impaired IL-12 production of mDCs in patients could lead to an impaired stimulatory capacity of naive T cells suggesting that IL-12 directed therapies may enhance tumor specific immune responses in HCC patients.

    Full Text Available Abstract Background The relationship between Human Papillomavirus (HPV infection and conjunctiva cancer is controversial. HPV detection will provide more information about the role of this infectious agent in the biology of conjunctiva cancer. In the present study, DNA extracted and purified from 36 Conjunctival Squamous Cell Carcinomas (CSCC was evaluated by PCR for HPV DNA sequences. The results were correlated with the clinical and histopathological variables. Results The results showed that HPV DNA was present in 8 CSCC samples (22%; HPV16 was the sole type detected. Significant association was found between HPV detection and the limbus tumor subtype (p = 0.03. All the samples were non-metastatic squamous cell carcinoma. Conclusions The HPV presence in CSCC from Mexican patients is not a common event.

    The aim of the present study was to clarify the therapeutic range and adequate dose of sunitinib in Japanese renal cell carcinoma patients by means of a pharmacokinetic-pharmacodynamic analysis of sunitinib-induced thrombocytopenia. Six patients with renal cell carcinoma were enrolled in this study. After starting the sunitinib treatment, between three and seven blood samples were obtained from each patient just before the administration of sunitinib. Serum concentrations of sunitinib and its active metabolite N-desethyl-sunitinib were fit to the 1-compartment model with first-order absorption. Changes in platelet counts were fit to the pharmacokinetic-pharmacodynamic model, in which the proliferation of platelet progenitor cells was assumed to be linearly inhibited by sunitinib and its metabolite. All patients using 50 mg as an initial dose of sunitinib developed grade 2 or 3 thrombocytopenia. The pharmacokinetic-pharmacodynamic model created successfully described the time course of sunitinib-induced thrombocytopenia and could predict changes in platelet counts after alterations to the dosage of sunitinib administered. The simulation results indicated that the total trough level of sunitinib to avoid severe thrombocytopenia should be Japanese patients. In addition to the pharmacokinetic-guided dosage adjustment, the careful monitoring of platelet counts is required for the safe use of sunitinib.

    Full Text Available Up to half of all patients with squamous cell carcinoma of the oropharyngeal area start their treatment when they have malnutrition that results from the primary disease. The main causes of weight loss in oropharyngeal tumors are pain syndrome and dysphagia of various etiologies, which lead to malnutrition and dehydration, as well as intoxication caused by tumor lysis and contamination. This results in impaired metabolic processes, worsening the general condition of patients. During further antitumor therapy, the manifestations of malnutrition are only aggravated, which is due to the high toxicity of chemoradiation therapy and the traumaticity of surgical interventions.

    Both long-term administration of immunosuppressive agents and chronic inflammatory conditions, such as autoimmune disease, could be risk factors for the development of cutaneous squamous cell carcinoma (cSCC). In this report, we present a case of recurrent multiple cSCC on the scalp in a patient with juvenile dermatomyositis who had been administered cyclosporine and Predonine since she was a 1-year-old infant. Interestingly, immunohistochemical staining revealed IL-17-producing cells adjacent to IL-17R-expressing atypical keratinocytes. Our present case suggested that IL-17/IL-17R signaling might contribute to the carcinogenesis of cSCC. PMID:28203172

    Primary squamous cell carcinoma of the pancreas is a rare malignant neoplasia, accounting for approximately 0.5-2% of all malignant pancreatic tumors. These lesions are characterized by poor prognosis. Here we report on a case of a 57-year-old female patient with known BRCA2 germline mutation presenting with primary squamous cell carcinoma of the pancreas as the only malignancy. The tumor was locally advanced at the first presentation but responded almost completely to neoadjuvant radio-chemotherapy. Our case highlights the facts (i) that pancreatic carcinomas belong to the tumor spectrum of patients with the BRCA2-associated hereditary breast and ovarian cancer syndrome (HBOC) and (ii) that tumors of the pancreas can represent the first or even the only manifestation of HBOC. Furthermore, this case of a nonkeratinizing squamous cell carcinoma indicates that HBOC-associated carcinomas of the pancreas might be characterized by a broader morphological spectrum than was previously thought. Since BRCA mutations cause deficiency of DNA double-strand breakage repair in tumors, neoadjuvant treatment regimens might become a reasonable option in HBOC-associated pancreatic carcinomas. To our knowledge, this is the first reported case of a primary pancreatic squamous cell carcinoma in a patient with this particular genetic background of BRCA2-associated HBOC.

    Objective To gather preliminary data concerning the feasibility of using salivary basic fibroblast growth factor (bFGF) for detecting development of oral squamous cell carcinoma (OSCC) in oral lichen planus (OLP) patients, and in OSCC patients whose disease was in remission. Study Design Saliva samples were collected from five patient groups: newly diagnosed OSCC patients; OSCC patients in remission; OLP patients in disease-active state; OLP patients in disease-inactive state; and normal controls. Salivary bFGF levels were determined by ELISA, and data was analyzed using the Mann Whitney U test. Results Salivary bFGF levels were significantly elevated in newly diagnosed OSCC patients compared with OSCC remission patients, disease-active OLP patients, and normal controls. No significant difference was found between newly diagnosed OSCC patients and disease-inactive OLP patients. Conclusion Our results suggested that salivary bFGF might be a potential biomarker for detecting OSCC development in OSCC patients in remission, but not in OLP patients. PMID:22769407

    Full Text Available The association of squamous cell carcinoma of the larynx with thyroid papillary carcinoma is an unusual finding. From 2004 to 2011, approximately 250 patients underwent laryngectomies due to squamous cell carcinoma of the larynx at the Otolaryngology Department of Khalili Hospital, affiliated with Shiraz University of Medical Sciences, Shiraz, Iran. In three patients, synchronous occurrence of squamous cell carcinoma and thyroid papillary carcinoma was found. Histopathologic study of the lymph nodes revealed metastatic papillary thyroid carcinoma in one case. We report three cases of thyroid papillary carcinoma incidentally found on histological examinations of resected thyroid lobes, as a procedure required for treatment of head and neck squamous cell carcinoma. In comparison, laryngeal squamous cell carcinoma needs more aggressive treatment than well-differentiated thyroid carcinoma. The prevalence of thyroid papillary carcinoma, as an incidental finding in our study was 0.01%. Therefore, preoperative evaluation of the thyroid gland by ultrasonography and fine needle aspiration biopsy of suspicious lesions is recommended in patients who are candidates for open laryngectomy.

    We report hyperamylasemia, macroamylasemia, and a markedly increased amylase clearance/creatinine clearance ratio in a patient with renal cell carcinoma. Serum amylase activity was characterized as macroamylase by gel exclusion chromatography. Electrophoretic separation revealed an atypical band of amylase, migrating anodal to the S2 control fraction. Electrophoresis of urine revealed the presence of both S1 and S2 fractions, but not the atypical band found in serum. Quantification of the salivary- and pancreatic-type amylase fractions showed amylase in urine to be 100% salivary. Immunofixation disclosed the macroamylase to consist of an immune complex between amylase and IgA-lambda antibody. Binding-capacity studies showed that the serum immunoglobulin was present in excess and could bind 46% and 49% additional S-type amylase activity derived from saliva and the patient's urine, respectively. The amylase clearance/creatinine clearance ratio was markedly supranormal (0.134), unexpected in a patient with macroamylasemia. A biopsy specimen of the renal cell tumor was found to contain significant salivary-type amylase activity. These results suggest production of amylase by tumor tissue in the renal carcinoma and secretion of S-type amylase into the patient's urine. Evidently, macroamylase should be confirmed by gel exclusion chromatography.

    Full Text Available Sorafenib, a multikinase inhibitor, is approved for treatment of renal cell cancer and hepatocellular cancer. Hand-foot syndrome (HFD is a condition where erythema, scaling, and bullous lesion affect the hand and feet. In this case, a post-nephrectomy renal carcinoma patient prescribed sorafenib developed HFD 1 week after the drug usage. All laboratory parameters were within normal limits. The dose of sorafenib was reduced and topical corticosteroids, antihistamines, and emollients were prescribed. The reaction reduced after 2 weeks of therapy, only to reappear again when the second cycle of sorafenib-targeted therapy was started. The case was diagnosed as sorafenib-induced HFD.

    AIM: To assess whether the molecular markers of malignant tumors could improve the understanding of tumor characteristics, and to observe the characteristics of expression of cell cycle markers Ki-67 and cydin A in esophageal carcinoma and to analyze the relationship between proliferative activity of cancer cells and clinicopathological factors.METHODS: Seventy of surgically resected esophageal squamous cell carcinoma (SCC) were examined by immunohistochemistry utilizing commercially available antibodies. Nuclear staining was regarded as a positive result. At least 50 fields in each tumor and non-tumor section were evaluated at a medium power (x200) to determine the proportion of tumor cells and the staining intensity of nuclei in the entire sections.RESULTS: Ki-67 and cyclin A were only expressed in base cells of normal esophageal mucosa. The positive immunostaining of nuclei of SCC was significantly higher than that in normal esophageal mucosa (t= 13.32 and t= 7.52,respectively, P<0.01). The distribution of positively stained was more diffuse and stronger in poorly differentiated SCC. Both Ki-67 and cyclin A expressions were related to histological grades of tumors (t = 3.5675 and t = 3.916; t= 2.13, respectively, P<0.05) but not to the sex and age of the patients, tumor size, lymphatic invasion, location, or stage grouping.CONCLUSION: The proliferative activity of cancer cells may be understood by immunohistochemistry of Ki-67 and cyclin A in Chinese patients with esophageal SCC. These cell cycle markers may serve as an indicator of cancer cell proliferation rate. The overexpression of cell cycle markers Ki-67 and cyclin A suggests the poor SCC differentiation in patients with esophageal carcinoma.

    Overall, head and neck sqamous cell carcinoma accounts for more than 550,000 cases annually worldwide. It is well known that human papillomavirus (HPV) is the main risk factor for cervical cancer development. As the incidence and the mortality of cervical cancer are closely related to the HPV prevalence, we hypothesized that there is the same association between HPV prevalence and head and neck squamous cell carcinoma. Therefore we performed the study aiming to compare the level of HPV infection and HPV type distribution between two groups of Lithuanian and Belarusian patients with head and neck sqamous cell carcinoma. One hundred ninety head and neck sqamous cell carcinoma patients were included in the study, 75 from Lithuania and 115 from Belarus. PCR was used for HPV detection and typing. The distribution of HPV infection among head and neck sqamous cell carcinoma patients was similar in the Lithuanian (20.0%) and Belarusian (18.3%) patient groups, however differences were found in the distribution of HPV types.

    AIM: To elucidate the immunologic parameters for the outcome of patients with malignant tumors, especially esophageal squamous cell carcinoma (ESCC) associated with high malignant potential.METHODS: Clinicopathologic features were compared between patients with lower and higher CD4 and CD8values as well as CD4/CD8 ratio in peripheral blood.RESULTS: The survival rate of patients with higher CD4 value was significantly better than that in patients with lower CD4 value (P = 0.039). The survival rate of patients with higher CD8 value was significantly worse than that of patients with lower CD8 value (P = 0.026).Similarly, the survival rate of patients with higher CD4/CD8 ratio was significantly better than that of patients with lower CD4/CD8 ratio (P = 0.042). Additionally,multivariate analysis demonstrated that lower CD8and lower CD4/CD8 ratio were factors independently associated with worse prognosis of patients.CONCLUSION: All the immunologic parameters can predict the outcome of patients with ESCC.

    Renal cell carcinoma (RCC) with rhabdoid differentiation is thought to portend a poor prognosis, similar to RCC with sarcomatoid differentiation. Both features are currently classified as grade 4 RCC based on the most recent International Society of Urological Pathology (ISUP) grading system. We reviewed a large series of patients with grade 4 RCC to determine the differential effects of rhabdoid and sarcomatoid differentiation on patient outcome. We identified 406 patients with ISUP grade 4 RCC including 111 (27%) with rhabdoid differentiation. In multivariable analysis of grade 4 RCC tumors, the presence of rhabdoid differentiation was not associated with death from RCC (hazard ratio [HR]: 0.95; p=0.75); in contrast, sarcomatoid differentiation was significantly associated with death from RCC (HR: 1.63; pISUP grade 4 category.

    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.

    Full Text Available Background: We conducted a retrospective analysis to evaluate overall survival(OAS and disease free survival (DFS rates in patients with squamous cell carcinoma of the urinary bladder according to different prognostic factors. Methods: This retrospective study analyzed the medical records of patients with non-metastatic squamous cell carcinoma of the urinary bladder. All men underwent radical cystectomy and women underwent anterior pelvic exentration. Most patients had postoperative radiation therapy. The log-rank test examined differences in OASand DFS rates. Results: The medical records of 106 patients were analyzed. The median follow-up from the date of enrollment was 30 months and ranged from 2 to 73 months. For the entire group, three-year OAS rates were 46.9% and DFS rates were 44%. For patients with P2 (tumor invasion into the muscularis propria the three-year OAS rate was 53%, for P3 (tumor invasion into perivesical fat it was 45% and 9% for P4 (tumor invasion into adjacent organs, pelvic wall or abdominal wall The OAS rate was statistically significant in favor of P2 disease (P=0.0041. The three-year DFS rate was 50% for P2, 45% for P3 and 9% for P4 disease (P=0.0125. Administration of post-operative radiotherapy did not result in statistically significant improvement in three-year OASand DFS rates. Conclusion: Survival rates were statistically significant and higher in patients with P2 and P3 disease compared to P4 disease. Adjuvant radiotherapy did not result in statistically significant survival improvement.

    Full Text Available Ronald M BukowskiCleveland Clinic Taussig Cancer Center, Cleveland Clinic Foundation, Cleveland, OH, USAAbstract: The management of renal cell carcinoma (RCC has undergone significant changes during the past 10 years, with the treatment of metastatic RCC undergoing the most radical changes. These developments reflect an enhanced understanding of this tumor's underlying biology, which was then translated into the development of a new treatment paradigm. Current therapeutic approaches for the management of patients with metastatic RCC utilize knowledge of histology, molecular abnormalities, clinical prognostic factors, the natural history of this malignancy, and the treatment efficacy and toxicity of available agents. The treatment options available for patients with metastatic RCC have changed dramatically over the past 6 years. Interferon-α and interleukin-2 were the previous mainstays of therapy, but since December 2005, six new agents have been approved in the US for the treatment of advanced RCC. Three are multi-targeted tyrosine kinase inhibitors (TKI including sunitinib, sorafenib, and pazopanib, two target the mammalian target of rapamycin (temsirolimus and everolimus, and one is a humanized monoclonal antibody (bevacizumab in combination with interferon-α. The current review focuses on the newest TKI available to treat patients with metastatic RCC, pazopanib. The development of this agent both preclinically and clinically is reviewed. The efficacy and safety data from the pivotal clinical trials are discussed, and the potential role of pazopanib in the treatment of patients with metastatic RCC in comparison to other treatment alternatives is critically appraised. This agent has a favorable overall risk benefit, and the available data demonstrate efficacy in patients with metastatic RCC who are either treatment-naïve or cytokine refractory. It therefore represents another alternative for treatment of metastatic RCC patients

    Since oral squamous cell carcinoma (OSCC) is one of the most important causes of death worldwide, the prevention and early detection plays a crucial role. Recent epidemiological studies have incriminated diabetes as a risk factor for the development of OSCC, as well as oral premalignant lesions. As for the last 20 years diabetes and oral squamous cell carcinoma rates have been increasing rapidly, therefore a reliable detection method of major saliva proteins as possible biomarkers for OSCC is of key priority. In this study we collected whole saliva samples from patients with diabetes and from healthy subjects. To reduce the risk of failure and to keep the investigation good reproducible, we proposed an examination and saliva collecting technique. The proteins were analyzed using SDS-PAGE and MALDI TOF/TOF mass spectrometry. Our findings show that the expression of Annexin A8, Peroxiredoxin-2 and Tyrosine kinase is elevated by patients having diabetes. All these proteins have been previously described in cancer saliva samples also in OSCC. Our current findings showed that testing saliva may be an effective and reliable method for detecting oral cancer in early stages.

    Full Text Available Background. The perception that older cancer patients may be at higher risk than younger patients of toxic effects from cancer therapy but may obtain less clinical benefit from it may be based on the underrepresentation of older patients in clinical trials and the known toxic effects of cytotoxic chemotherapy. It is not known how older patients respond to targeted therapy.Methods.  This retrospective subgroup analysis of data from the phase 3, randomized Treatment Approach in Renal Cancer Global Evaluation Trial examined the safety and efficacy of sorafenib in older (age ≥ 70 years, n = 115 and younger patients (age <70 years, n = 787 who received treatment for advanced renal cell carcinoma. Patient demographics and progression-free survival were recorded. Best tumor response, clinical benefit rate (defined as complete response plus partial response plus stable disease, time to self-reported health status deterioration, and toxic effects were assessed by descriptive statistics. Health-related quality of life was assessed with a Cox proportion- al hazards model. Kaplan - Meier analyses were used to summarize time-to-event data.Results. Median progression-free survival was similar in sorafenib-treated younger patients (23.9 weeks; hazard ratio [HR] for progression compared with placebo = 0.55, 95% confidence interval [CI] = 0.47 to 0.66 and older patients (26.3 weeks; HR = 0.43, 95% CI = 0.26 to 0.69. Clinical benefit rates among younger and older sorafenib-treated patients were also similar (83.5% and 84.3%, respectively and were superior to those of younger and older placebo-treated patients (53.8% and 62.2%, respectively. Adverse events were predictable and manageable regardless of age. Sorafenib treatment delayed the time to self-reported health status deterioration among both older patients (121 days with sorafenib vs 85 days with placebo; HR = 0.66, 95% CI = 0.43 to 1.03 and younger patients (90 days with sorafenib vs 52 days with placebo

    Sorafenib is a tyrosine kinase inhibitor (TKI) of the vascular endothelial growth factor receptor (VEGFR) used for advanced renal cell carcinoma. Treatment with sorafenib prolongs progression-free survival in patients with advanced clear-cell renal cell carcinoma. However, in spite of its therapeutic efficacy, sorafenib causes a wide range of adverse events. Cardiovascular adverse events have been observed when sorafenib was used with targeted agents. Although these adverse events like hypertension, reduced left ventricular ejection fraction, cardiac ischemia or infarction were manageable with standard medical therapies in most cases, some had a poor clinical outcome. We report three cases of acute myocardial infarction associated with sorafenib in patients with metastatic renal cell carcinoma.

    OBJECTIVE To investigate the detection rate of human papilloma virus (HPV) DNA in the Kazakh esophageal carcinoma (EC) patients of Xinjiang.METHODS We detected the prevalence of a HPV gene in tumor tissues from 318 esophageal squamous cell carcinoma (ESCC).Tumor tissues were kept in formalin and embedded in paraffin.One hundred seventeen samples used crude cell suspension, while the other 201 used the method of DNA extraction with phenol-Tris/chloroform. We analyzed the relevance to EC of Kazakh's in Xinjiang.RESULTS In the ESCC samples of Kazakh's in Xinjiang, total detection rate for HPV DNA was 64.5% (205/318). The positive rate of HPV in group of crude cell suspensions was 82.9% (97/117) compared with the rate of 53.7% (108/201) in the group of DNA extraction. The results in the two groups showed significant diffference (X2 = 5.711, P < 0.05).CONCLUSION HPV DNA infection may be one of the most important factors related to EC of Kazakh's in Xinjiang.

    Full Text Available The aim of this study is to evaluate tumor angiogenesis in patients with non-small cell lung carcinoma. A total of 20 patients with pulmonary adenocarinoma have been included in the study. In order to evaluate tumor angiogenesis we studied the importance of CD34 expression. Evaluation of vascular density was performed with a semiautomated method using the dedicated software called ImageJ. We introduced in our study 20 patients with lung adenocarcinoma. We were able to identify tumor angiogenesis in 19 cases (95%. Immunolabeling of CD34 positive endothelial cells provided a good overview of tumor vascularization. Immunohistochemical staining of CD34 positive endothelium cells provided a good basis for tumor vascularity assessment, and also an excellent contrast for computer assisted morphometric measurements. Also we studied the intensity of the immunohistochemical staining of CD34 in the tumoral cells. We obtained the following results: a minor expression in 4 cases (20%, a moderate expression in 9 cases (45% and an intense expression in 6 cases (30%. The histological type of adenocarcinomas influences the architecture and branching of the vessels. The density of newly developed vessels is higher in patients with papillary pulmonary adenocarcinomas, which may indicate a possible relationship between the histological type and development of vascular supply.

    Renato Fortes Bittar

    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 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.

    Full Text Available Renal cell carcinoma (RCC is one of the most urgent topics in modern oncourology. This is attributable to the high morbidity and mortality rates associated with this pathology. Renal dystopia is a rather rare developmental anomaly. The literature data describing cases of the diagnosis and treatment in patients with dystopic kidney malignancies are scarce. Moreover, if a tumor is present in the solitary dystopic kidney, it is often extremely difficult to perform an organ-saving operation for a number of features of the anatomic structure of the dystopic kidney and its vascular architectonics. The paper describes a clinical case of S-shaped crossed dystopic kidney resection in a patient with RCC.

    A 36-year-old African man from Guinea with a history of albinism presented with a many-year history of scaling and erythema of the face, neck, and arms. The patient had light eyes, hair, and skin. Physical examination showed extensive photodamage. A skin biopsy specimen from the posterior aspect of the lower leg showed a squamous-cell carcinoma in situ. The most common types of oculocutaneous albinism (OCA), OCA 1 and OCA 2, are autosomal recessive disorders of pigmentation that commonly affect the skin, hair, eyes, and ears. Photodamage and skin cancers plague patients with albinism. In Africa, where albinism is prevalent, albinos face a myriad of social and medical issues. Skin cancer surveillance is an important consideration for albinos, and sun protection is paramount.

    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 Background: Oral cancers are one of the ten leading cancers in the world. However, in India, it is one of the most common cancer and constitutes a major public health problem. Aim: The purpose of this study was to evaluate, retrospectively, the epidemiologic profile of patients with oral squamous cell carcinoma (OSCC. Materials and Methods: OSCC cases were retrospectively analyzed from January 2008 to September 2010 for age, gender, occupation, duration of the symptoms, habits (tobacco and alcohol consumption, site of primary tumor, and TNM staging, and the findings were formulated to chart the trends in central India population. Results: Male to female ratio was 4.18:1. Mean age was 49.73 years. The most common site of presentation of tumor was in mandibular alveolus region. Tobacco chewing was the major cause for the development of OSCC. Maximum number of patients, i.e., 201 (68.14% were presented within 6 months of onset of symptoms. Majority of patients were presented in Stage III (82.37%. Correlation between the two variables, i.e., site to habits, staging to site involved, staging to duration of the disease, staging to habits, and staging to age of the patient, were found to be statistically nonsignificant (P>0.05. Conclusions: The aim of the study was the demographic description of oral squamous cell carcinoma. Most of the cases report at advanced stages of the disease which often leads to delay in the management coupled with the fact that health care centers are burdened with long waiting lists. Strategies to overcome the present situation must be undertaken by oral health programs for the early diagnosis and prevention and management and follow up of oral cancer.

    Although undifferentiated carcinoma (UC) and squamous cell carcinoma (SCC) of the nasopharynx are regarded as two distinct histopathologic and clinical entities, it is unclear whether, like UC, SCC carries Epstein-Barr virus (EBV) genomes. We used the polymerase chain reaction (PCR) on paraffin-embedded biopsy specimens to test for the presence of EBV DNA in 20 cases of UC and 9 cases of SCC. Multiple copies of the viral genome were regularly detected in all UCs; however, of the nine cases of SCC, seven had no detectable EBV DNA and two contained viral genomes in a low copy number. In parallel, a marked difference in the serum levels of anti-EBV antibodies between patients with UC and SCC was found. Our findings provide evidence for the specific association of EBV with UC in Italian patients and prove by means of a highly sensitive molecular technique that SCC is occasionally related to EBV DNA. Because of the absence of EBV DNA in most cases of SCC and the minimal viral DNA copy number in the few EBV-associated cases of SCC, a different pathway of oncogenic transformation and growth of the nasopharyngeal epithelium is suggested for SCC and UC.

    Objective: Although renal sinus fat invasion has prognostic significance in patients with renal cell carcinomas (RCCs), there are no previous studies about the value of multidetector computed tomography (MDCT) about this issue in the current literature. Materials and methods: A total of 863 consecutive patients (renal sinus fat invasion in 110 patients (12.7%)) from single institutions with surgically-confirmed renal cell carcinoma who underwent MDCT between 2010 and 2012 were included in this study. The area under the curves (AUCs) of the receiver operating characteristic (ROC) analysis was used to compare diagnostic performance. Reference standard was pathologic examination. Weighted κ statistics were used to measure the level of interobserver agreement. Multivariate logistic regression model was used to find the predictors for renal sinus fat invasion. Image analysis was first performed with axial-only CT images. A second analysis was then performed with both axial and coronal CT images. A qualitative analysis was then conducted by two reviewers who reached consensus regarding tumor size, decreased perfusion, tumor margin, vessel displacement, and lymph node metastasis. The reference standard was pathologic evaluation. Results: The AUCs of the ROC analysis were 0.881 and 0.922 for axial-only images and 0.889 and 0.902 for combined images in both readers. The AUC of tumor size was 0.884, a similar value to that of the reviewers. In multivariate analysis, tumor size, a linear-nodular or nodular type of fat infiltration, and an irregular tumor margin were independent predicting factors for perinephric fat invasion. Conclusion: MDCT shows relatively high diagnostic performance in detecting perinephric fat invasion of RCC but suffers from a relatively low PPV related to low prevalence of renal sinus fat invasion. Applying tumor size alone we could get similar diagnostic performance to those of radiologists. Tumor size, fat infiltration with a nodular appearance, and

  12. Basal Cell Carcinoma in Gorlin's Patients: a Matter of Fibroblasts-Led Protumoral Microenvironment?

    Directory of Open Access Journals (Sweden)

    Full Text Available 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 Ji-Feng Feng, Qi-Xun Chen Department of Thoracic Surgery, Zhejiang Cancer Hospital, Key Laboratory Diagnosis and Treatment Technology on Thoracic Oncology, Hangzhou, People's Republic of China Background: The prognostic nutritional index (PNI is related to the prognosis in many cancers; however, its role in esophageal cancer is still controversial. Further, controversy exists concerning the optimal cut-off points for PNI to predict survival. The aim of this study was to determine the prognostic value of PNI and propose the optimal cut-off points for PNI in predicting cancer-specific survival (CSS in esophageal squamous cell carcinoma (ESCC. Methods: This retrospective study included 375 patients who underwent esophagectomy for ESCC. The PNI was calculated as 10 × serum albumin (g/dL + 0.005 × total lymphocyte count (per mm3. With the help of the fit line on the scatter plot, we classified the patients into three categories according to the PNI, ie, >52, 42–52, and <42. Results: Our study showed that PNI was associated with tumor length (P=0.007, T grade (P=0.001, and N staging (P<0.001. The 5-year CSS in patients with PNI <42, 42–52, and >52 were 11.0%, 39.1%, and 55.2%, respectively (P<0.001. Multivariate analysis showed that PNI was a significant predictor of CSS (42–52 versus >52, P=0.011; <42 versus PNI >52, P<0.001. Conclusion: PNI is a predictive factor for long-term survival in ESCC. The survival rate of ESCC can be discriminated between three groups, ie, PNI ,42, 42–52, and .52.

    Surgical and radiation therapy for oral squamous cell carcinoma (OSCC) may generate orofacial pain. The aims of this study were to (1) characterize the pain experienced by people with orofacial pain, and (2) determine the factors associated with changes in orofacial pain in OSCC patients during the postoperative and post-radiation therapy periods. The study had a prospective longitudinal design with consecutive sampling. Seventy-two eligible patients were recruited from the outpatient department of otolaryngology, head and neck cancer, and radiation therapy of a medical center in northern Taiwan. A set of questionnaires was used for patient assessment, including the University of California San Francisco Oral Cancer Pain Questionnaire, Symptom Severity Scale, Hospital Anxiety and Depression Scale, and Karnofsky's Performance Status Index. Patients were assessed at two time points: 1 month after surgery (T1) and 1 month after completion of radiation treatment (T2). The findings showed that (1) patients reported moderate orofacial pain at both time points; (2) orofacial pain, oral function-related symptoms, and psychological distress were significantly higher at T1 than at T2; and (3) older age, eating difficulty, speech difficulty, and depression were significant predictors of orofacial pain. Oral rehabilitation and relaxation training may reduce orofacial pain in this patient population.

    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

    Merkel cell carcinoma (MCC) is a rare, aggressive neuroendocrine carcinoma of the skin. Although it is 40 times less common than malignant melanoma, its mortality is much higher compared to melanoma. From 1986 to 2001 there was rapidly increasing incidence in reported cases of MCC, with a tripling in the rate over this 15-year period. The vast majority of MCC presents on sun-exposed skin. The head and neck area is the most common site of tumor occurrence. We present 70-year old female patient with painless red-colored nodule, size 2 x 2 x 2 cm on the dorsal side of mid left forearm. The surgical excision with negative margins was performed, and pathohistological analysis confirmed Merkel cell carcinoma. Sentinel lymph node biopsy was negative. In conclusion, as MCC is a very aggressive rare skin carcinoma with lethal outcome, it should be mandatory to perform biopsies of any suspected skin lesion.

    Full Text Available Abstract 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. In 133 stages II + III patients receiving surgery, absence of preoperative bone scan was significantly associated with inferior bone recurrence

    Full Text Available Abstract Background Intratumoral and circulating regulatory T cells (Tregs have been shown to be critical in the pathogenesis of hepatocellular carcinoma (HCC. However there is limited knowledge on the alterations of regulatory B cells (Bregs. We here investigated perioperative dynamic alterations of peripheral circulating Tregs and Bregs in HCC patients to reveal the relationship between regulatory lymphocytes and its clinical implications. Methods 36 patients with HCC, 6 with chronic hepatitis B infection and 10 healthy donors were enrolled for this study. Frequencies of peripheral Tregs and Bregs were measured by flow cytometry with antibodies against CD4, CD25, CD127, CD19 and IL-10 before, and after radical surgery. Then, clinical informatics of HCC patients was achieved through Digital Evaluation Score System (DESS for the assessment of disease severity. Finally, we analysed correlations between digitalized clinical features and kinetics of circulating regulatory lymphocytes. Results Level of circulating CD4+CD25+CD127- Tregs in HCC patients was significantly lower than that in healthy donors and patients with chronic hepatitis B infection before surgery, but was increased after surgery. Preoperative level of CD19+ IL-10+ Bregs in HCC patients was also significantly lower than the other groups. However it dramatically was elevated right after surgery and remained elevated compared to controls (about 7 days after surgery, P = 0.04. Frequency of circulating Tregs was correlated with circulating leukocytes, ferritin, and clinical features suggesting tumor aggressiveness including portal vein thrombosis, hepatic vein involvement and advanced clinical stages. Frequency of circulating Bregs was associated with Hepatitis B e Antigen (HBeAg and Hepatitis B virus (HBV DNA copy number. In addition, DESS was significantly and positively correlated with other staging systems. Conclusion Frequencies of peripheral Tregs and Bregs in HCC patients

    Full Text Available Abstract Background In experimental systems, interference with coagulation can affect tumor biology. We suggested that abnormal coagulation could be a negative predictor for response to immunotherapy and survival among patients with metastatic renal cell carcinoma (MRCC. Methods To address this issue, retrospective analysis of 289 previously untreated MRCC patients entering on institutional review board-approved clinical trials was conducted between 2003 and 2006. In addition, two groups of MRCC patients with (n = 28 or without (n = 28 hypercoagulability were compared in a case-control study. Baseline and treatment characteristics were well balanced. Results Hypercoagulability was present at treatment start in 40% of patients. Median baseline fibrinogen was 6.2 mg/dl. Serious disorders were found in 68% of patients. Abnormal coagulation was strongly associated with a number of metastatic sites (2 and more metastatic sites vs. 0–1 (P = .001. Patients with high extent of hypercoagulability had significantly higher number of metastatic sites (P = .02. On univariate analysis, patients with hypercoagulability had significantly shorter overall survival than patients with normal coagulation; median survivals of 8.9 and 16.3, respectively (P = .001. Short survival and low response rate also were significantly associated with hypercoagulability in a case-control study. Median survival was 8.2 months and 14.6 months, respectively (P = .0011. Disease control rate (overall response + stable disease was significantly higher in patients with normal coagulation: 71.4 versus 42.9% (P = .003. Conclusion Hypercoagulability disorders were found to be prognostic factor for response rate to systemic therapy and survival in patients with MRCC.

    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.

    Full Text Available Merkel cell carcinoma is a rare primary cutaneous tumor. So far, few cases have been reported.  Herewith we report a case of an 87-years-old male with painless, ulceroproliferative growth measuring 6x6 cm, over right upper outer quadrant of buttock; stage IIB (TNM, T3cNoMo. Patient received neo-adjuvant chemotherapy, injection of carboplatin 420 mg (day one and etoposide 140 mg (day one to three three weekly for three cycles followed external beam radiotherapy by Cobalt 60. At three months post-treatment follow-up, clinically no evidence of residual disease or recurrences noted. The purpose of reporting this case was to emphasize to its rarity, early asymptomatic clinical course leading to possibility of delayed diagnosis and paramount importance of high index of clinical suspicion in definitive diagnosis for better treatment result.

    The prognosis of renal cell carcinoma (RCC) with venous tumour thrombus (VTT) is variable and not always possible to predict. The prognostic impact and independence of tumour thrombus-related factors including the recently introduced tumour thrombus consistency (TTC) on overall survival remain controversial. The aim of this study was to investigate the prognostic role of TTC in patients' survival. We determined the tumour thrombus consistency (solid vs. friable) in a cohort of 84 patients with RCC and VTT who underwent nephrectomy with thrombectomy, and performed a retrospective evaluation of the patients' data from the prospectively maintained database. A total of 45% of patients had solid thrombus (sTT) and 55% had friable thrombus (fTT). The venous tumour thrombus consistency was not predictive of overall survival. Further studies, preferably prospective and with a larger number of patients, are needed to validate the obtained results, as well as to evaluate the usefulness of tumour thrombus consistency in clinical practice for stratifying the risk of recurrence and planning further follow-up.

    Full Text Available Objective: to estimate the rate, predictive and prognostic value of VHL gene alterations in the population of patients with sporadic metastatic renal cell carcinoma (mRCC.Subjects and methods. Paraffin embedded tumor tissue blocks were available from 88 patients with mRCC who had undergone antitumor therapy in 1994- 2010. Of them, 53 patients received only immunotherapy regimens with interferon (IFN-α and 35 patients had targeted therapy with VEGFR inhibitors. VHL mutations were detected by polymerase chain reaction (PCR for exons of 1-3, single-strand conformation polymorphism analysis of PCR products, and further sequencing.

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

    Full Text Available Statement of Problem: Many studies have indicated that genetic disturbances are common findings in patients with Oral Squamous Cell Carcinoma (OSCC. Identification of these changes can be helpful in diagnostic procedures of these tumors.Purpose: The aim of this study was to appraise the chromosomal disorders in blood and tissue patients with OSCC.Methods and Materials: In this descriptive study, the study group consisted of all OSCC patients who were referred to the Faculty of Dentistry, Tehran University of Medical Sciences, Maxillofacial Surgery Clinic of Shariati Hospital, and Amir Aalam Hospital fromSeptember 2000 to November 2002. In order to study chromosomal disorders in the peripheral blood lymphocytes, 5 mL of blood was obtained from each patient In patients with the large lesion, a piece of involved tissue were obtained and cultured for 24 hours.This led to 29 blood samples and 16 tissue specimens and any relation between OSCC and age, sex, smoking and alcohol use were evaluated.Results: In this study, OSCC was more common in males than in females (3 to 5. 31% of our patients were smokers, and one had a history of alcoholic consumption. There was an increase in incidence of OSCC with age. In this study, all patients had numerical(aneuploidy, polyploidy and structural chromosomal disorders (double minute, fragment,breakage and dicentric. There was significant difference between blood and tissue chromosomal disorders (aneuploidy, polyploidy,breakage in OSCC patients.Conclusion: It can be concluded that chromosomes in patients with OSCC might show some genetic aberration and evaluation of involved tissue might be better way for determining this disorders.

    Study Design Case report. Objective Merkel cell carcinoma (MCC), an uncommon cutaneous neuroendocrine malignancy, is a rare cause of spinal metastasis, with only five cases previously reported. We report a rare case of MCC metastatic to the spine in an immunocompromised patient. Methods A 55-year-old male with previously resected MCC, immunocompromised due to cardiac transplant, presented with sharp mid-thoracic back pain radiating around the trunk to the midline. Computed tomography of the thoracic spine showed a dorsal epidural mass from T6 to T8 with compression of the spinal cord. Laminectomy and subtotal tumor resection were performed, and pathology confirmed Merkel cell tumor through immunohistochemistry staining positive for cytokeratin 20 and negative for thyroid transcription factor-1. Results Further treatment with radiation therapy was initiated, and the patient did well for 4 months after surgery, but returned with a lesion in the cervical spine. He then opted for hospice care. Conclusions With an increasing number of immunocompromised patients presenting with back pain, MCC should be considered in the differential diagnosis of spinal metastatic disease.

    We undertook a study of tumour infiltrating lymphocytes (TILs) in a large and relatively homogeneous group of patients with completely resected esophageal squamous cell carcinoma (ESCC). Hematoxylin and eosin-stained sections of 235 ESCC tumours were evaluated for density of TILs in intratumoural (iTIL) and stromal compartments (sTIL). Foxp3+, CD4+, and CD8+ T cells in tumoural and stromal areas were evaluated by immunohistochemistry. Of the 235 tumours, high sTIL (>10%), and iTIL (>10%) were observed in 101 (43.0%) and 98 (41.7%), respectively. The median follow-up period was 36.0 months (95% CI 29.929-42.071). Univariate analysis revealed that sTIL (>10%), iTIL (>20%), vessels involvement, lymph node metastasis, and clinical stage were significantly associated with postoperative outcome. In multivariate analysis, high sTIL (HR: 0.664, P = 0.019 for Disease free survival; HR: 0.608, P = 0.005 for Overall survival) was identified as independent better prognostic factor. Further analysis, sTIL was identified as independently prognostic factor in Stage III-IVa disease, which was not found in Stage I-II disease. Our study demonstrated that sTIL was associated with better ESCC patients' survival, especially in Stage III-IVa disease. Assessment of sTIL could be useful to discriminate biological behavior for ESCC patients.

    Full Text Available Oral cancer, more specifically oral squamous cell carcinoma (OSCC consider as common cancer that 300,000 people diagnosed per year worldwide. The only effective treatment for OSCC is surgical intervention. Over the past two decades, overall disease condition has not improved although advancement of treatment has considerably increased. The phosphodiesterase (PDEs are responsible for the hydrolysis of the second messengers with a fundamental role in the transduction of the intracellular signals. In numerous pathological conditions such as cellular differentiation, apoptosis, and tumor invasivity the different PDF activity has been observed that shown role in pathophysiological mechanism. The role of PDEs as an intervention factor for activation of angiogenesis by influencing a tumor growth has been shown. The objective of this study was to estimate and compare salivary PDEs levels in healthy controls and biopsy-proven oral cancer patients before definitive therapy. Study was done in patients age between 25-65 years biopsy proven oral cancer patients and control group. After obtaining prior consent from biopsy-proven oral cancer patients (n=26 (before onset of any definitive treatment and age- and sex-matched healthy controls (n=29, salivary sample was collected for estimation of the activity of phosphodiesterases (PDEs.

    Full Text Available Background: Oral Squamous Cell Carcinoma (OSCC is commonly noted in elder men, when occurring in younger individuals, its aggression and prognosis is questioned due to biased data in literature. Traditionally, various histopathological grading systems have been used for assessing aggression and prognosis of OSCC. However, multifactorial grading of Anneroth et al., is considered effective. Materials and Methods: In this retro-prospective study, files of 75 OSCC patients were retrieved from Oral Pathology Department; among this 50 patients were >40 years and 25 patients were ≤40 years of age. Archival formalin fixed paraffin embedded tissue blocks of these patients were used to prepare hematoxylin and eosin (H and E stained sections for grading OSCC based on Broder′s and Anneroth et al., criteria. Further, recurrence of OSCC among study subjects within 5 years of treatment was evaluated. Chi-square test was used to compare the disease in patients who were >40 years with ≤40 years. Results: Comparison according to Broder′s classification didn′t show any relevant variation. Three of the six parameters and overall grading according to Anneroth et al., criteria showed statistically higher grades of OSCC in the younger age-group; however, there was no significant difference in 5-year recurrence rate. Interpretation and Conclusion: Results of the study are suggestive of aggressive OSCC among young patients when compared to older. Conversely, this aggression didn′t affect the recurrence in younger patients. Further studies on genetics, diet and demographics of patients below 40 years of age affected by OSCC will be of greater value.

    Full Text Available Abstract Background Renal cell carcinoma (RCC has multiple symptoms stemming from disease and treatments. There are few validated scales for evaluating RCC symptoms. Methods A national cross-sectional study of adult RCC patients was conducted from October to December 2003 to define patient-reported RCC symptomology. Participants were asked open-ended questions regarding their signs and symptoms and completed an 86-item pilot questionnaire of physical and psychological symptoms. Patients were asked to rate the relevancy and clarity of each pilot question using a 5-point Likert scale. Subsequent open-ended caregiver interviews and a provider panel relevance ranking contributed additional information. Results The average age of the participants (n = 31 was 55 years; 55% of patients were male, 74% had attended college, and 97% were Caucasian. The five most frequent symptoms among localized-stage patients (n = 14 were irritability (79%, pain (71%, fatigue (71%, worry (71%, and sleep disturbance (64%. Among metastatic patients (n = 17, the five most frequent symptoms were fatigue (82%, weakness (65%, worry (65%, shortness of breath (53%, and irritability (53%. More than 50% of localized and metastatic-stage patients reported pain, weakness, fatigue, sleep disturbance, urinary frequency, worry, and mood disorders as being moderately to highly relevant. Conclusion A brief, self-administered RCC Symptom Index was created that captures the relevant signs and symptoms of both localized and metastatic patients. Pending additional content validation, the Index can be used to assess the signs and symptoms of RCC and the clinical benefit resulting from RCC treatment.

    Urothelial cell carcinoma (UCC) includes urothelial bladder carcinoma (UBC), renal pelvic carcinoma (RPC) and ureter carcinoma (UC), and its incidence varies dependent on geographical areas and tumor locations, which indicates different oncogenic mechanisms and/or different genetic susceptibility/environment exposure. The activating mutations of the fibroblast growth factor receptor 3 (FGFR3) gene and telomerase reverse transcriptase (TERT) promoter are the most frequent genetic events in UCCs. These mutations have clinical utilities in UCC initial diagnostics, prognosis, recurrence monitoring and management. However, the vast majority of the results are obtained from studies of UCC patients in Western countries, and little has been known about these in Han Chinese patients. In the present study, we screened the FGFR3 gene and TERT promoter for mutations in 116 UBC, 91 RPC and 115 UC tumors from Han Chinese patients by using Sanger Sequencing. TERT promoter mutations occurred at a high frequency in these UCC patients, comparable with that seen in Western patients, however, the FGFR3 mutation was surprisingly lower, only 9.4% for UBCs, 8.8% for RPCs and 2.6% for UCs, respectively. Taken together, the FGFR3 gene is an infrequent target in the pathogenesis of Han Chinese UCCs, and its mutation detection and targeted therapy have limited clinical utility in these patients. Our results underscore the need for extensive characterization of cancer genomes from diverse patient populations, thereby contributing to precision medicine for cancer treatment and prevention.

    2001-01-01

    @@Eosinophilic ulcer of oral mucosa (EUOM) is a nonspecific clinical appeara nce, which appears to be frequently unrecognized or misdiagnosed usual ly as squamous cell carcinoma (SCC), especially in old patients. It i s a rare self-limited benign ulcerative disease, and it is characterized with t he infiltration of eosinophilic leukocytes mixed with other inflammatory cells, 1,2 such as th e mitotically active large mononuclear cells with round or ovoid pale nu cleus. This cell type, often interpreted as a histiocyte, confounds the histolog ic evaluation and occasionally leads to the erroneous diagnosis of lymphohistioc ytic malignant condition. Although it has assumed that trauma is an important et iologic factor, the exact pathogenesis remains unclear.3 The morbidity of this disease is low and there are few Chinese literatures about it,4 so it is n ecessary to pay more attention to it. In this article, 3 out of 5 cases of EU OM are misdiagnosed as SCC, and we will report the records in order to identify it from SCC well.

    Full Text Available Abstract Background The association between human papillomavirus (HPV infection and non-melanoma skin cancers (NMSCs such as squamous cell carcinoma (SCC and basal cell carcinoma (BCC is not yet fully understood. We analysed the prevalence and spectrum of cutaneous beta-HPV types and mucosal/genital HPV types in paired biopsies (tumour and corresponding perilesional skin obtained from 50 BCC immunocompetent patients. A small group of SCC patients (n=9 was also included. We also evaluated some previously postulated risk factors for HPV infection in NMSC patients. Results All biopsies were negative for mucosal/genital HPV types. Overall, beta-HPV DNA was detected more often in SCC compared to BCC patients (78% vs 55% of total samples. The frequency of infection increased with the patient’s age [OR=4.88 (95% CI 1.29-18.39]. There was no significant correlation between beta-HPV positivity and sex, skin type and UV exposure. The prevalence of beta-HPV species 1 types was significantly higher than those belonging to other beta-HPV species in biopsies from BCC (p=0.022 but not from SCC subjects (p=0.091. There was no significant difference in the overall prevalence of beta-HPV infection and the number of viral types between tumour lesions and perilesional skin. BCC samples were significantly more likely to be infected with beta-HPV species 1 types compared to perilesional skin (p=0.036 and showed a higher frequency of mixed infections (p=0.028. Conclusions These findings demonstrate that beta-HPV types belonging to species 1 are the most common HPV types detected in the skin of BCC patients. Moreover beta-1-HPV types and mixed infections are significantly more frequent in tumour samples than in healthy perilesional skin. Our results suggest that beta-1-HPVs as well as co-infection with more than one viral type could be important in NMSC and in particular in BCC. Further studies aimed to compare the biological activity of viral types in tumours and in

    Background and study aims: Multiple squamous cell carcinomas (SCCs) frequently arise in the upper aerodigestive tract, referred to as the field cancerization phenomenon. The aim of this study was to elucidate the detailed clinical features of second primary head and neck (H&N) SCCs arising in patients with esophageal SCC. Patients and methods: A total of 818 patients underwent endoscopic resection for superficial esophageal cancer between January 2006 and December 2013. Of these, 439 patients met our inclusion criteria, and we retrospectively investigated the incidence, primary sites, and stages of second primary H&N SCCs in these patients. Results: A total of 53 metachronous H&N SCCs developed in 40 patients after a median follow-up period of 46 months (range 9 – 109). The cumulative incidence rates of metachronous H&N SCCs at 3, 5, and 7 years were 5.3 %, 9.7 %, and 17.2 %, respectively. These lesions were frequently located at pyriform sinus or in the posterior wall of the pharynx (70 %, 37/53 lesions). Most of the lesions were detected at an early stage, though 4 lesions were associated with lymph node metastasis when their primary sites were detected (1 postcricoid area, 2 posterior wall of hypopharynx, and 1 lateral wall of oropharynx). Conclusions: Patients with esophageal SCC should undergo careful inspection of the pyriform sinus and posterior wall of the pharynx for detection of H&N SCCs. Methods to open the hypopharyngeal space, such as the Valsalva maneuver, should be included in the surveillance program. PMID:27556090

    Pseudoepitheliomatous hyperplasia is a benign condition that may be caused by prolonged inflammation, chronic infection, and/or neoplastic conditions of the mucous membranes or skin. Due to its histological resemblance to well-differentiated squamous cell carcinoma, pseudoepitheliomatous hyperplasia may occasionally be misdiagnosed as squamous cell carcinoma. The importance of pseudoepitheliomatous hyperplasia is that it is a self-limited condition that must be distinguished from squamous cell carcinoma before invasive treatment. We report here on a rare case of esophageal pseudoepitheliomatous hyperplasia in a 67-year-old Korean woman with a lye-induced esophageal stricture. Although esophageal pseudoepitheliomatous hyperplasia is infrequently encountered, pseudoepitheliomatous hyperplasia should be considered in the differential diagnosis of esophageal lesions.

    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.

    Four cases of distinctive radiation-induced pneumonitis with severe clinical symptoms were observed during combined therapy of 52 patients with small-cell bronchial carcinoma. Withdrawal of corticosteroids was identified as the most probable cause, due to the fact that a time correlation between cortison withdrawal and the onset of clinical symptoms was found in all four patients. Possible consequences for future therapy measures are pointed out.

    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.

    Background The coagulation function in carcinoma patients is abnormal, but in renal cell carcinoma the extent and relationships of coagulation function remain unclear. This study retrospectively investigated the relationships between coagulation function, clinical stage and metastasis in patients with renal cell carcinoma.Methods A total of 350 consecutive patients admitted to our Urology Department from 2004 to 2010 were diagnosed with renal cell carcinoma by histolopathologic examination and were included in this study. A total of 231 cases of renal benign tumors were considered as the control group. Fibrinogen, prothrombin time, activated partial thromboplastin time and international normalized ratio were evaluated in all subjects. Tumor size, clinical stage, lymph node metastasis, and distant metastasis were evaluated using radiologic imaging, intraoperative findings, and histological studies.Results The preoperative plasma fibrinogen levels of patients with renal cell carcinoma ((383.9±146.7) mg/dl) were significantly higher than those of the control group ((316.7±62.0) mg/dl) (P <0.01). We divided the renal cell carcinoma group into stages la, lb, Ⅱ, Ⅲ, and Ⅳ. The fibrinogen values were (315.6±64.6) mg/dl, (358.3±91.1) mg/dl, (465.6±164.7)mg/dl, (500.0±202.1) mg/dl, and (585.8±179.7) mg/dl, respectively. There were no significant differences in fibrinogen values between stage la and control groups. However, results of other stages showed significant differences when compared to control group values (P <0.01). Using the cutoff value of 440 mg/dl, which defines hyperfibrinogenemia,plasma fibrinogen levels had a positive predictive value of 39.8% and a negative predictive value of 93.3% for predicting distant metastasis, with a sensitivity of 64.7% and specificity of 83.3%.Concluslons Preoperative plasma fibrinogen levels are elevated in patients with renal cell carcinoma with distant metastasis or lymph node metastasis. Potential metastasis is

    Heparan sulfate-specific endosulfatase-2 (SULF-2) can modulate the signaling of heparan sulfate proteoglycan-binding proteins. The involvement of SULF-2 in cancer growth varies by cancer type. The roles of SULF-2 expression in the progression and prognosis of renal cell carcinomas (RCC) have not yet been fully clarified. In the present study, the expression levels of SULF-2 mRNA and protein in 49 clinical RCC samples were determined by RT-PCR and immunostaining. The existence of RCC with higher SULF-2 expression and lower SULF-2 expression compared to the adjacent normal kidney tissues was suggested. High SULF-2 expression was correlated with an early clinical stage and less invasive pathological factors. Low SULF-2 expression was correlated with an advanced stage and higher invasive factors. Three-year cancer-specific survival (CSS) for high SULF-2 RCC and low SULF-2 RCC were 100% and 71.4%, respectively (log-rank P = 0.0019), with a significantly shorter CSS observed in low SULF-2 RCC patients. The influence of SULF-2 expression level on Wnt/VEGF/FGF signaling, cell viability and invasive properties was examined in three RCC cell lines, Caki-2, ACHN and 786-O, using a SULF-2 suppression model involving siRNA or a SULF-2 overexpression model involving a plasmid vector. High SULF-2 expression enhanced Wnt signaling and Wnt-induced cell viability, but not cell invasion. In contrast, low levels of SULF-2 expression significantly enhanced both cell invasion and viability through the activation of VEGF/FGF pathways. RCC with lower SULF-2 expression might have a higher potential for cell invasion and proliferation, leading to a poorer prognosis via the activation of VEGF and/or FGF signaling.

    Objective: To study recurrence factors and set up a model to evaluate the prognosis of patients with bladder cancer.Methods: An analysis on recurrence-related factors was made by Cox's proportional hazards model analysis and logistic multiple linear regression model analysis in 212 patients with transitional cell carcinoma treated surgically from 1995~2001.These factors included clinical and pathologic figures. Results: The most important factor is metastasis to the regional lymph nodes, the Hazards ratio is 6.6 (P=0.0004), followed by multiple tumors (Hr=2.255, P<0.0001), tumor in trigone and bladder neck (Hr=2.053, P<0.0001), stage (Hr=2.057, P<0.0001), grade (Hr=1.569, P=0.0081), intravesical chemotherapeutic instillations (Hr-0.559, P=0.0011) and hematuria (Hr=0.762, P=0.0076). A predicting equation was established, and the predicting values were calculated according to the individual features of patients. The predicting and actual values were compared, and the sensitivity, specificity and overall concordance were 83.5%, 67.6% and 80.1% respectively. Conclusion:The evaluation of prognosis could be made quite accurately based on these factors.

    Full Text Available Abstract Background Tyrosine kinase inhibitors (TKIs are currently approved for the treatment of metastatic renal cell carcinoma (mRCC. The cardiotoxic effects of sorafenib and sunitinib may cause hypertension, left ventricular ejection fraction (LVEF dysfunction and/or congestive heart failure (CHF, and arterial thrombo-embolic events (ATE. Only three cases of coronary artery disease related to sorafenib therapy have been described in the literature, and all were due to arterial vasospasm without evidence of coronary artery stenosis on angiography. Cardiotoxicity is commonly associated with the presence of cardiovascular risk factors, such as a history of hypertension or coronary artery disease. Case presentation We describe a patient who experienced an unusual cardiac event after 2 years of sorafenib treatment. A 58-year-old man with mRCC developed acute coronary syndrome (ischemia/infarction associated with critical sub-occlusion of the common trunk of the left coronary artery and some of its branches, which was documented on coronary angiography. The patient underwent triple coronary artery bypass surgery, and sorafenib treatment was discontinued. He did not have any cardiovascular risk factors, and his cardiac function and morphology were normal prior to sorafenib treatment. Conclusions Further investigation of a larger patient population is needed to better understand cardiac damage due to TKI treatment. Understanding the usefulness of careful cardiovascular monitoring might be important for the prevention of fatal cardiovascular events, and to avoid discontinuation of therapy for the underlying cancer.

    Full Text Available Definitive cytomorphologic diagnosis of small cell carcinoma of the uterine cervix is possible but can be challenging in routine cervicovaginal cancer screening specimens. Several small series of reported cases of cervical small cell carcinoma have shown this uncommon malignancy to represent fewer than 2% of all invasive cervical cancers. This tumor type is associated with poor prognosis and rapid disease progression and can develop to an advanced stage in the interval between screening visits. Only rare case reports of small cell carcinoma arising in gravid cervices are known. In the current case a 29-year-old, gravida 6, para 2, pregnant (10-week gestation female presented with postcoital bleeding. A definitive diagnosis of small cell carcinoma of the cervix was made possible by liquid based Pap testing with ancillary cell block preparation allowing for immunocytochemical characterization of the lesional cell population.

    AIM: The aim of the study was to evaluate the predictive factors of survival in patients with locally advanced squamous cell esophageal carcinoma (LASCOC) treated with definitive chemoradiotherapy (CRT)regimen based on the 5FU/CDDP combination.METHODS: All patients with LASCOC treated with a definitive CRT using the 5FU/CDDP combination between 1994 and 2000 were retrospectively included.Clinical complete response (CCR) to CRT was assessed by esophageal endoscopy and CT-scan 2 mo after CRT completion. Prognostic factors of survival were assessed using univariate and multivariate analysis by the Cox regression model.RESULTS: A total of 116 patients were included in the study. A CCR to CRT was observed in 86/116 (74.1%).The median survival was 20 mo (range 2-114) and the 5-year survival was 9.4%. Median survival of responder patients to CRT was 25 mo (range 3-114) as compared to 9 mo (range 2-81) in non-responder patients (P <0.001). In univariate analysis, survival was associated with CCR (P < 0.001), WHO performance status < 2 (P= 0.01), tumour length < 6 cm (P = 0.045) and weight loss < 10% was in limit of significance (P = 0.053). In multivariate analysis, survival was dependant to CCR (P< 0.0001), weight loss < 10% (P = 0.034) and WHO performance < 2 (P = 0.046).CONCLUSION: Our results suggest that survival in patients with LASCOC treated with definitive CRT was correlated to CCR, weight loss and WHO performance status.

    The management of renal cell carcinoma (RCC) has undergone significant changes during the past 10 years, with the treatment of metastatic RCC undergoing the most radical changes. These developments reflect an enhanced understanding of this tumor's underlying biology, which was then translated into the development of a new treatment paradigm. Current therapeutic approaches for the management of patients with metastatic RCC utilize knowledge of histology, molecular abnormalities, clinical prognostic factors, the natural history of this malignancy, and the treatment efficacy and toxicity of available agents. The treatment options available for patients with metastatic RCC have changed dramatically over the past 6 years. Interferon-α and interleukin-2 were the previous mainstays of therapy, but since December 2005, six new agents have been approved in the US for the treatment of advanced RCC. Three are multi-targeted tyrosine kinase inhibitors (TKI) including sunitinib, sorafenib, and pazopanib, two target the mammalian target of rapamycin (temsirolimus and everolimus), and one is a humanized monoclonal antibody (bevacizumab in combination with interferon-α). The current review focuses on the newest TKI available to treat patients with metastatic RCC, pazopanib. The development of this agent both preclinically and clinically is reviewed. The efficacy and safety data from the pivotal clinical trials are discussed, and the potential role of pazopanib in the treatment of patients with metastatic RCC in comparison to other treatment alternatives is critically appraised. This agent has a favorable overall risk benefit, and the available data demonstrate efficacy in patients with metastatic RCC who are either treatment-naïve or cytokine refractory. It therefore represents another alternative for treatment of metastatic RCC patients.

    Full Text Available Background: Basal cell carcinoma of the nose is common, with a potential of local recurrence and high-risk features. Materials and Methods: We provide a review on anatomy of the nose, tumour surgery and defect closure on the nose. We analysed our own patients with nasal BCC of a 24 months period. Results: We identified 321 patients with nasal BCC. There was a predominance of female patients of 1.2 to 1. The mean age was 74.8 years. Slow Mohs technique was employed for all tumours until 3D tumour-free margins were achieved. That resulted on average in 1.8 ± 0.7 Mohs stages. The most common histologic types were solitary (n = 182, morpheic (79, and micronodular (20, Perineural infiltration was evident in 56 tumours. Primary closure after mobilisation of soft tissue was possible in 105 BCCs. Advancement flaps were used in 91 tumours, rotation flaps in 47, transposition flaps in 34 tumours, and combined procedures in 6 cases. In 36 patients full-thickness skin grafting was performed. In two patients healing by second intention was preferred. Partial flap loss was seen in four patients (1.4%. All of them had significant underlying pathologies. None of the tumours treated showed a relapse during the observation time. However, this is a limitation of the present study since follow-up was on average only 10 months. Conclusions: BCCs of the nose are common. Only 3D-controlled micrographic surgery (Mohs or slow Mohs guarantee a high rate of complete tumour removal and a very low risk of recurrence.

    Renal cell carcinoma represents approximately 3% of adult malignancies and 90-95% of neoplasms arising from the kidney. Many agents that target angiogenesis (e.g., sunitinib, sorafenib, bevacizumab and pazopanib) and mTOR-targeted therapy (e.g., temsirolimus and everolimus) have been approved as first-line agents. The choice of the most suitable treatment for advanced renal cell carcinoma depends on the definition of risk. In this article, we reviewed the scientific literature identifying predictive factors on the activity/efficacy of a specific therapy.

    Human papillomavirus (HPV) is a major etiologic factor for oropharyngeal squamous cell carcinoma (OPSCC). However, little is known about HPV-related OPSCC in Japan. During the study, formalin-fixed, paraffin-embedded OPSCC specimens from Japanese patients were analyzed for HPV DNA by the polymerase chain reaction (PCR) and for the surrogate marker p16 by immuno-histochemistry. For HPV DNA-positive, p16-negative specimens, the methylation status of the p16 gene promoter was examined by methylation-specific PCR. Overall survival was calculated in relation to HPV DNA and p16 status and was subjected to multivariate analysis. OPSCC cell lines were examined for sensitivity to radiation or cisplatin in vitro. The study results showed that tumor specimens from 40 (38%) of the 104 study patients contained HPV DNA, with such positivity being associated with tumors of the tonsils, lymph node metastasis, and nonsmoking. Overall survival was better for OPSCC patients with HPV DNA than for those without it (hazard ratio, 0.214; 95% confidence interval, 0.074-0.614; P = 0.002). Multivariate analysis revealed HPV DNA to be an independent prognostic factor for overall survival (P = 0.015). Expression of p16 was associated with HPV DNA positivity. However, 20% of HPV DNA-positive tumors were negative for p16, with most of these tumors manifesting DNA methylation at the p16 gene promoter. Radiation or cisplatin sensitivity did not differ between OPSCC cell lines positive or negative for HPV DNA. Thus, positivity for HPV DNA identifies a distinct clinical subset of OPSCC with a more favorable outcome in Japanese.

    Renal cell carcinoma (RCC) associated with neuroblastoma (NB) was included as a distinct entity in the 2004 World Health Organization classification of kidney tumors. A spectrum of RCC subtypes has been reported in NB survivors. We herein describe a series of 8 RCCs diagnosed in 7 patients with a history of NB. Microscopic evaluation, immunohistochemical staining for PAX8, cathepsin K, and succinate dehydrogenase subunit B (SDHB), and fluorescence in situ hybridization (FISH) for TFE3 and TFEB were performed. Four distinct morphologic subtypes were identified: 3 tumors were characterized by cells with abundant oncocytoid cytoplasm and irregular nuclei; 3 showed features of microphthalmia transcription factor family translocation RCC (MiTF-RCC); 1 had features of hybrid oncocytic-chromophobe tumor; 1 had papillary RCC histology. All RCCs expressed PAX8 and retained SDHB expression. Cathepsin K was positive in 2 MiTF-RCCs, 1 was TFEB FISH positive, and the other was indeterminate. Cathepsin K was negative in a third MiTF-RCC with TFE3 rearrangement. TFE3 FISH was negative in 4 and insufficient in 1 of the other 5 RCCs. While a subset of RCCs associated with NB is characterized by cells with prominent oncocytoid cytoplasm, other RCC subtypes also occur in post-NB patients. Renal neoplasms occurring in patients with a history of NB do not represent a single entity but a heterogenous group of RCCs. SDHB mutations do not explain the subset of nontranslocation RCCs with oncocytoid features; therefore, further studies are needed to clarify whether they may represent a distinct entity with unique molecular abnormalities or may belong to other emerging RCC subtypes.

    Since the introduction of combination antiretroviral therapy (ART), the life expectancy has increased for patients infected with human immunodeficiency virus (HIV). This has been associated with reductions in the incidences of some AIDS-defining malignancies, such as Kaposi sarcoma and non-Hodgkin lymphoma, but has coincided with an increased incidence of non-AIDS-defining malignancies, such as anal cancer. However, anal cancers are rare in patients with HIV in Japan. We report the case of an HIV-infected patient with anal cancer treated with chemoradiotherapy. A 37-year-old man receiving ART for HIV infection presented with a 1-month history of left inguinal lymphadenopathy and anal pain. Magnetic resonance imaging and computed tomography revealed a 56-mm mass, left inguinal lymphadenopathy, and left external iliac lymphadenopathy. The mass had infiltrated from the anal canal to the right levator ani and corpus spongiosum. Colonoscopy revealed a tumor with an ulcer in the anal canal. Histological examination of the tumor biopsy specimens confirmed the diagnosis of squamous cell carcinoma. The patient was diagnosed with anal cancer (T4N2M1 stage IV), and he received 5-fluorouracil (1000mg/m(2) on days 1-4 and 29-32) plus mitomycin C (10mg/m(2) on days 1 and 29) and concurrent radiotherapy (total dose, 59.4Gy in 33 fractions) along with ART. The treatment-related adverse events were grade 4 leukopenia and neutropenia, grade 3 thrombocytopenia, and grade 2 radiation dermatitis. Moreover, CD4 suppression was observed:the CD4 count decreased from 190 cells/μl before chemoradiotherapy to 138 cells/μl after 3 months, but increased to 210 cells/μl after 1 year. Because of the grade 4 leukopenia and neutropenia, the dose of 5-fluorouracil was reduced to 800mg/m(2) on days 29-32. A complete response was confirmed on magnetic resonance imaging, and colonoscopy confirmed the disappearance of the anal cancer. The patient is living with no signs of recurrence at 2 years

    The best treatment for advanced esophageal cancer is chemoradiotherapy followed by surgery. In spite of the advance of multimodality therapy, most patients with esophageal cancer are treated with radiation therapy alone. This study reports the outcome of the use of conventional external beam radiotherapy alone for the treatment of esophageal cancer. Between January 1998 and December 2005, 30 patients with squamous cell carcinoma of the esophagus were treated with external beam radiotherapy using a total dose exceeding 40 Gy. Radiotherapy was delivered with a total dose of 44-60 Gy (median dose, 57.2 Gy) over 36 {approx}115 days (median time, 45 days). Thirteen patients (43.3%) had a history of disorders such as diabetes, hypertension, tuberculosis, lye stricture, asthma, cerebral infarct, and cancers. Four patients metachronously had double primary cancers. The most common location of a tumor was the mid-thoracic portion of the esophagus (56.7%). Tumor lengths ranged from 2 cm to 11 cm, with a median length of 6 cm. For AJCC staging, stage III was the most common (63.3%). Five patients had metastases at diagnosis. The median overall survival was 8.3 months. The survival rates at 1-year and 2-years were 33.3% and 18.7%, respectively. The complete response rate 1{approx}3 months after radiotherapy was 20% (6/30) and the partial response rate was 70% (21/30). Sixteen patients (53.3%) had an improved symptom of dysphagia. Significant prognostic factors were age, tumor length, stage, degree of dysphagia at the time of diagnosis and tumor response. Cox regression analysis revealed the aim of treatment, clinical tumor response and tumor length as independent prognostic factors for overall survival. Twenty-eight patients had local failure and another four patients had metastases. Three patients were detected with double primary cancers in this analysis. A complication of esophageal stricture was observed in three patients (10%), and radiation pneumonitis occurred in two

    The aim of our study was to explore the clinicopathological and prognostic significance of extracellular matrix metalloproteinase inducer (EMMPRIN) expression in oral squamous cell carcinomas (OSCC), and its relation with the proliferative tumor status of OSCC. We examined EMMPRIN and Ki-67 proteins expression by immunohistochemistry in 74 cases with OSCC. Statistical analysis was conducted to examine their clinicopathological and prognostic significance in OSCC. EMMPRIN membrane expression was observed in all cases, with both membrane and cytoplasmic tumor expression in 61 cases (82.4%). EMMPRIN overexpression was observed in 56 cases (75.7%). Moderately or poorly differentiated tumors showed EMMPRIN overexpression more frequently than well-differentiated tumors (P = 0.002). Overexpression of EMMPRIN was correlated with high Ki-67 expression (P = 0.004). In the multivariate analysis, EMMPRIN overexpression reveals an adverse independent prognostic value for cancer-specific survival (CSS) (P = 0.034). Our results reveal that EMMPRIN protein is overexpressed in more than two-thirds of OSCC cases, especially in high proliferative and less differentiated tumors. The independent value of EMMPRIN overexpression in CSS suggests that this protein could be used as an important biological prognostic marker for patients with OSCC. Moreover, the high expression of EMMPRIN makes it a possible therapeutic target in OSCC patients.

    Full Text Available Abstract Background We investigated the association between exposure to trichloroethylene (TCE and mutations in the von Hippel-Lindau (VHL gene and the subsequent risk for renal cell carcinoma (RCC. Methods Cases were recruited from a case-control study previously carried out in France that suggested an association between exposures to high levels of TCE and increased risk of RCC. From 87 cases of RCC recruited for the epidemiological study, 69 were included in the present study. All samples were evaluated by a pathologist in order to identify the histological subtype and then be able to focus on clear cell RCC. The majority of the tumour samples were fixed either in formalin or Bouin's solutions. The majority of the tumours were of the clear cell RCC subtype (48 including 2 cystic RCC. Mutation screening of the 3 VHL coding exons was carried out. A descriptive analysis was performed to compare exposed and non exposed cases of clear cell RCC in terms of prevalence of mutations in both groups. Results In the 48 cases of RCC, four VHL mutations were detected: within exon 1 (c.332G>A, p.Ser111Asn, at the exon 2 splice site (c.463+1G>C and c.463+2T>C and within exon 3 (c.506T>C, p.Leu169Pro. No difference was observed regarding the frequency of mutations in exposed versus unexposed groups: among the clear cell RCC, 25 had been exposed to TCE and 23 had no history of occupational exposure to TCE. Two patients with a mutation were identified in each group. Conclusion This study does not confirm the association between the number and type of VHL gene mutations and exposure to TCE previously described.

    Full Text Available The throat is an ecological assemblage involved human cells and microbiota, and the colonizing bacteria are important factors in balancing this environment. However, this bacterial community profile has thus been poorly investigated. The purpose of this study was to investigate the microbial biology of the larynx and to analyze the throat biodiversity in laryngeal carcinoma patients compared to a control population in a case-control study. Barcoded pyrosequencing analysis of the 16S rRNA gene was used. We collected tissue samples from 29 patients with laryngeal carcinoma and 31 control patients with vocal cord polyps. The findings of high-quality sequence datasets revealed 218 genera from 13 phyla in the laryngeal mucosa. The predominant communities of phyla in the larynx were Firmicutes (54%, Fusobacteria (17%, Bacteroidetes (15%, Proteobacteria (11%, and Actinobacteria (3%. The leading genera were Streptococcus (36%, Fusobacterium (15%, Prevotella (12%, Neisseria (6%, and Gemella (4%. The throat bacterial compositions were highly different between laryngeal carcinoma subjects and control population (p = 0.006. The abundance of the 26 genera was significantly different between the laryngeal cancer and control groups by metastats analysis (p<0.05. Fifteen genera may be associated with laryngeal carcinoma by partial least squares discriminant analysis (p<0.001. In summary, this study revealed the microbiota profiles in laryngeal mucosa from tissue specimens. The compositions of bacteria community in throat were different between laryngeal cancer patients and controls, and probably were related with this carcinoma. The disruption of this bio-ecological niche might be a risk factor for laryngeal carcinoma.

    Objective To compare the survival outcomes of patients with cervical squamous cell carcinoma (SCC) and adenocarcinoma/adenosquamous carcinoma (AC/ASC) among patients with locally advanced cervical cancer that were treated with definitive radiotherapy. Methods The baseline characteristics and outcome data of patients with locally advanced cervical cancer who were treated with definitive radiotherapy between November 1993 and February 2014 were collected and retrospectively reviewed. A Cox proportional hazards regression model was used to investigate the prognostic significance of AC/ASC histology. Results The patients with AC/ASC of the cervix exhibited significantly shorter overall survival (OS) (p=0.004) and progression-free survival (PFS) (p=0.002) than the patients with SCC of the cervix. Multivariate analysis showed that AC/ASC histology was an independent negative prognostic factor for PFS. Among the patients who displayed AC/ASC histology, larger tumor size, older age, and incomplete response to radiotherapy were found to be independent prognostic factors. PFS was inversely associated with the number of poor prognostic factors the patients exhibited (the estimated 1-year PFS rates; 100.0%, 77.8%, 42.8%, 0.0% for 0, 1, 2, 3 factors, respectively). Conclusion Locally advanced cervical cancer patients with AC/ASC histology experience significantly worse survival outcomes than those with SCC. Further clinical studies are warranted to develop a concurrent chemoradiotherapy (CCRT) protocol that is specifically tailored to locally advanced cervical AC/ASC. PMID:28028992

    Full Text Available Abstract Background To test if the expression of Smad1-8 mRNAs were predictive of survival in patients with oral squamous cell carcinoma (SCC. Patients and Methods We analyzed, prospectively, the expression of Smad1-8, by means of Ribonuclease Protection Assay in 48 primary, operable, oral SCC. In addition, 21 larynx, 10 oropharynx and 4 hypopharynx SCC and 65 matched adjacent mucosa, available for study, were also included. For survival analysis, patients were categorized as positive or negative for each Smad, according to median mRNA expression. We also performed real-time quantitative PCR (QRTPCR to asses the pattern of TGFβ1, TGFβ2, TGFβ3 in oral SCC. Results Our results showed that Smad2 and Smad6 mRNA expression were both associated with survival in Oral SCC patients. Cox Multivariate analysis revealed that Smad6 positivity and Smad2 negativity were both predictive of good prognosis for oral SCC patients, independent of lymph nodal status (P = 0.003 and P = 0.029, respectively. In addition, simultaneously Smad2- and Smad6+ oral SCC group of patients did not reach median overall survival (mOS whereas the mOS of Smad2+/Smad6- subgroup was 11.6 months (P = 0.004, univariate analysis. Regarding to TGFβ isoforms, we found that Smad2 mRNA and TGFβ1 mRNA were inversely correlated (p = 0.05, R = -0.33, and that seven of the eight TGFβ1+ patients were Smad2-. In larynx SCC, Smad7- patients did not reach mOS whereas mOS of Smad7+ patients were only 7.0 months (P = 0.04. No other correlations were found among Smad expression, clinico-pathological characteristics and survival in oral, larynx, hypopharynx, oropharynx or the entire head and neck SCC population. Conclusion Smad6 together with Smad2 may be prognostic factors, independent of nodal status in oral SCC after curative resection. The underlying mechanism which involves aberrant TGFβ signaling should be better clarified in the future.

    Purpose: To investigate whether single nucleotide polymorphisms (SNPs) in the ataxia telangiectasia mutated (ATM) gene are associated with survival in patients with esophageal squamous cell carcinoma (ESCC) receiving radiation therapy or chemoradiation therapy or surgery only. Methods and Materials: Four tagSNPs of ATM were genotyped in 412 individuals with clinical stage III or IV ESCC receiving radiation therapy or chemoradiation therapy, and in 388 individuals with stage I, II, or III ESCC treated with surgery only. Overall survival time of ESCC among different genotypes was estimated by Kaplan-Meier plot, and the significance was examined by log-rank test. The hazard ratios (HRs) and 95% confidence intervals (CIs) for death from ESCC among different genotypes were computed by a Cox proportional regression model. Results: We found 2 SNPs, rs664143 and rs664677, associated with survival time of ESCC patients receiving radiation therapy. Individuals with the rs664143A allele had poorer median survival time compared with the rs664143G allele (14.0 vs 20.0 months), with the HR for death being 1.45 (95% CI 1.12-1.89). Individuals with the rs664677C allele also had worse median survival time than those with the rs664677T allele (14.0 vs 23.5 months), with the HR of 1.57 (95% CI 1.18-2.08). Stratified analysis showed that these associations were present in both stage III and IV cancer and different radiation therapy techniques. Significant associations were also found between the SNPs and locosregional progression or progression-free survival. No association between these SNPs and survival time was detected in ESCC patients treated with surgery only. Conclusion: These results suggest that the ATM polymorphisms might serve as independent biomarkers for predicting prognosis in ESCC patients receiving radiation therapy.

    Although subungual squamous cell carcinoma is rare, it is the most common primary malignant neoplasms in this location. The higher incidence occurs in the fingernails, but involvement of the toenails is also possible. Subungual squamous cell carcinoma often looks like other more common benign lesions, such as fungal infection, onychomycosis, or viral wart. These factors, together with a general lack of awareness of this disease among physicians, often result in delayed diagnosis. Therefore, it is underdiagnosed, with few reports in the literature. The authors present a case of a man with a diagnosis of subungual squamous cell carcinoma in the hallux, without bone involvement, which was submitted to the appropriate surgical treatment.

    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.

    Full Text Available Renal cell carcinoma (RCC is a heterogeneous disease in which the patients survive for months to years. At the present time the prognostic models have no sufficient information or exact prognostic value. Cell proliferation and apoptosis play a key role in cell cycle regulation; and impairment in these processes is commonly detected in different human tumors. The investigation enrolled 76 patients (49 men, 27 women aged 32 to 73 years (mean age 56 ± 7.6 years diagnosed with RCC. The follow-up was 8 to 116 months (mean 36.5 months. All the patients underwent nephrectomy; antibodies against р53, Bcl-2, and Ki-67 were investigated by immunohistochemistry. The expression of p53 and none or reduced expression of Bcl-2 are poor prognostic factors and associated with the metastatic potential of a tumor and with low relapse-free survival. High Ki-67 levels are a risk factor for metastases. A combination of p53 expression and high proliferative activity reflects the aggressive potential of a tumor and suggests the high risk of metastases just at the disease diagnosis and early tumor dissemination.

    An 80-year-old man with prostate cancer receiving hormone therapy presented with urinary retention. The computed tomographic scan showed metastases to the lung, liver, and lymph nodes, as well as increased prostate volume. Transurethral resection of the prostate (TURP) was performed, and the resected specimen was pathologically found to be a small cell carcinoma of the prostate. The patient was treated with a combination of carboplatin and irinotecan, and achieved a partial response : size reduction of the prostate and the metastatic lesions, and decreased neuron specific enolase (NSE) level. The chemotherapy with carboplatin and irinotecan is reported to have fewer serious adverse effects, and equivalent efficacy to the cisplatin/etoposide chemotherapy. Therefore, this regimen could also be a treatment option for the patients with small cell carcinoma of the prostate.

    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.

  3. Monocarboxylate transporter 4 facilitates cell proliferation and migration and is associated with poor prognosis in oral squamous cell carcinoma patients.

    Directory of Open Access Journals (Sweden)

    Jiang Zhu

    Full Text Available Monocarboxylate transporter 4 (MCT4 is a cell membrane transporter of lactate. Recent studies have shown that MCT4 is over-expressed in various cancers; however, its role in cancer maintenance and aggressiveness has not been fully demonstrated. This study investigated the role of MCT4 in oral squamous cell carcinoma (OSCC, and found that it is highly expressed in OSCC patients by using immunohistochemistry. Moreover, this over-expression of MCT4 was closely associated with tumor size, TNM classification, lymphatic metastasis, distant metastasis and tumor recurrence, and also poor prognosis. To further study mechanisms of MCT4 in vitro, we used small-interfering RNA to silence its expression in OSCC cell lines. The results showed that knock-down of MCT4 decreased cell proliferation, migration, and invasion. The inhibition of proliferation was associated with down-regulation of p-AKT and p-ERK1/2, while decreased cell migration and invasion may be caused by down-regulation of integrin β4-SRC-FAK and MEK-ERK signaling. Together, these findings provide new insight into the critical role of MCT4 in cell proliferation and metastasis in OSCC.

    2004-01-01

    Anaplastic (giant cell) thyroid carcinoma (ATC), is one of the most aggressive malignancies in humans with a median survival time after diagnosis of 3-6 months. Death from ATC was earlier seen because of local growth and suffocation. ATC is uncommon, accounting for less than 5 % of all thyroid carcinomas. The diagnosis can be established by means of multiple fine needle aspiration biopsies, which are neither harmful nor troublesome for the patient. The cytological diagnosis of this high-grade malignant tumour is usually not difficult for a well trained cytologist. The intention to treat patients with ATC is cure, although only few of them survive. The majority of the patients are older than 60 years and treatment must be influenced by their high age. We have by using a combined modality regimen succeeded in achieving local control in most patients. Every effort should be made to control the primary tumour and thereby improve the quality of remaining life and it is important for patients, relatives and the personnel to know that cure is not impossible. Different treatment combinations have been used since 30 years including radiotherapy, cytostatic drugs and surgery, when feasible. In our latest combined regimen, 22 patients were treated with hyper fractionated radiotherapy 1.6Gy x 2 to a total target dose of 46 Gy given preoperatively, 20 mg doxorubicin was administered intravenously once weekly and surgery was carried out 2-3 weeks after the radiotherapy. 17 of these 22 patients were operated upon and none of these 17 patients got a local recurrence. In the future we are awaiting the development of new therapeutic approaches to this aggressive type of carcinoma. Inhibitors of angiogenesis might be useful. Combretastatin has displayed cytotoxicity against ATC cell lines and has had a positive effect on ATC in a patient. Sodium iodide symporter (NIS) genetherapy is also being currently considered for dedifferentiated thyroid carcinomas with the ultimate aim of

    Full Text Available Objective : To derive further studies evaluating the effectiveness of Cultured Wild Ginseng Pharmacopuncture (CWGP Therapy on squamous cell carcinoma as a first line. Methods : Three cycles (4 weeks/cycle of CWGP were administered as a dosage of 10 ml per day. Patient was diagnosed with stage IIIB squamous cell carcinoma and refused all therapy of conventional medicine because of old age and cardiac invasion of tumor. Intensive treatment of CWGP for 3 cycles was done on the patient. Computed Topography (CT was performed to evaluate the therapeutic efficacy. Results : After the intravenous infusion of 2 cycles of CWGP, chest CT revealed the mass size and pleural invasion sustained stable disease. After the point injection of 1 cycle of CWGP, chest CT revealed progressive disease. The disease free survival rate was 1 month. Conclusion : This case may provide us the possibility that CWGP offers potential benefits for patients with squamous cell lung carcinoma. But this is a single case study and further case-series research should be compensated.

    Chromoendoscopy with Lugol's staining remains the gold standard technique for detecting superficial SCC. An alternative technique, such as narrow-band imaging (NBI), for "optical staining" would be desirable, since NBI is a simpler technique and has no known complications. In this study, we compare NBI without magnification and chromoendoscopy with Lugol's staining for detecting high-grade dysplasia and intramucosal esophageal squamous cell carcinoma (SCC) in patients with achalasia. This was a prospective observational study of 43 patients with achalasia referred to the Gastrointestinal Endoscopy Unit of the Hospital of Clinics, São Paulo, University Medical School, Brazil, from October 2006 to February 2007. Conventional examinations with white light, NBI, and Lugol staining were consecutively performed, and the suspected lesions were mapped, recorded, and sent for biopsy. The results of the three methods were compared regarding sensitivity, specificity, accuracy, positive predictive value, negative predictive value, positive likelihood value, and negative likelihood value. Of the 43 patients, one was diagnosed with esophageal squamous cell carcinoma, and it was detected by all of the methods. NBI technology without magnification has high sensitivity and negative predictive value for detecting superficial esophageal squamous cell carcinoma, and it has comparable results with those obtained with Lugol's staining.

    Full Text Available Chromoendoscopy with Lugol's staining remains the gold standard technique for detecting superficial SCC. An alternative technique, such as narrow-band imaging (NBI, for “optical staining” would be desirable, since NBI is a simpler technique and has no known complications. In this study, we compare NBI without magnification and chromoendoscopy with Lugol's staining for detecting high-grade dysplasia and intramucosal esophageal squamous cell carcinoma (SCC in patients with achalasia. This was a prospective observational study of 43 patients with achalasia referred to the Gastrointestinal Endoscopy Unit of the Hospital of Clinics, São Paulo, University Medical School, Brazil, from October 2006 to February 2007. Conventional examinations with white light, NBI, and Lugol staining were consecutively performed, and the suspected lesions were mapped, recorded, and sent for biopsy. The results of the three methods were compared regarding sensitivity, specificity, accuracy, positive predictive value, negative predictive value, positive likelihood value, and negative likelihood value. Of the 43 patients, one was diagnosed with esophageal squamous cell carcinoma, and it was detected by all of the methods. NBI technology without magnification has high sensitivity and negative predictive value for detecting superficial esophageal squamous cell carcinoma, and it has comparable results with those obtained with Lugol's staining.

    Oral cancer is the leading cause of death worldwide and it is the eighth most common cause of cancer death. Cancer cells utilize more glucose and amino acids than their benign counterparts. Diagnosis of disease via the analysis of saliva is potentially valuable, as the collection of fluid is associated with fewer compliance problems than the collection of blood. Hence, the present study was undertaken to evaluate the comprehensive amino acid profiling of saliva by high performance liquid chromatography (HPLC). The study group comprised 16 subjects, of whom eight were classified as having well-differentiated oral squamous (OSCC) cell carcinoma (Group I) and eight were classified as having moderately differentiated oral squamous cell carcinoma (Group II). Eight healthy individuals comprised the control group (Group III). The results showed increased salivary levels of all the amino acids in both groups of OSCC patients (Groups I and II) when compared with healthy controls (Group III). Hence, our study showed higher levels of all amino acids in the saliva of OSCC patients than in the saliva of healthy controls. The increased levels may serve as a "diagnostic and prognostic marker" for oral squamous cell carcinoma and for further detection of metastatic spread.

    Background The clinical and histopathological characteristics of basal cell carcinoma (BCC) have been relatively well studied in Caucasian population.To characterize BCC in Chinese population,we analyzed the association of the histopathological subtypes with gender,age and anatomical location in this study.Methods The clinical and histopathological data of 243 BCC cases diagnosed at three hospitals in Beijing from January 2000 to April 2009 were reviewed retrospectively.Gender,age,location and histopathological subtype were analyzed.Results Among 243 patients enrolled,118 were males and 125 were females.The male/female ratio was 0.94∶1.The mean age was (65.16±12.62) years old.The head and neck were the most common sites of BCC (77.4%).Of the BCCs,53.9% were nodular,18.9% superficial and 18.5% infiltrative-morphoeic.The nodular,infiltrative-morphoeic and micronodular subtypes were predominant located on the head and neck,whereas the trunk was the most common location for the superficial subtype (P <0.05).The age at first presentation for females was lower than that for males (P<0.05).The age at first presentation for the superficial BCCs was younger than the non-superficial subtypes (P <0.05).Women with superficial BCC subtype visited hospital earlier than men (P <0.05).Conclusions Consistent with previous reports in Caucasian patient,our study find that different histopathological subtypes of BCC has distinct clinical features.It is speculated that the mechanisms underlining the pathogenesis of the superficial BCC may be different than those of non-superficial subtypes of BCC.

  16. Differing von Hippel Lindau genotype in paired primary and metastatic tumors in patients with clear cell renal cell carcinoma

    Full Text Available In sporadic clear cell renal cell carcinoma (CCRCC, the von Hippel Lindau (VHL gene is inactivated by mutation or methylation in the majority of primary (P tumors. Due to differing effects of wild-type (WT and mutant (MT VHL gene on downstream signaling pathways regulating angiogenesis, VHL gene status could impact clinical outcome. In CCRCC, comparative genomic hybridization (CGH analysis studies have reported genetic differences between paired P and metastatic (M tumors. We thus sequenced the VHL gene in paired tumor specimens from 10 patients to determine a possible clonal relationship between the P tumor and M lesion(s in patients with CCRCC. Using paraffin embedded specimens, genomic DNA from microdissected samples (>80% tumor of paired P tumor and M lesions from all 10 patients, as well as in normal tissue from 6 of these cases, was analyzed. The DNA was used for PCR-based amplification of each of the 3 exons of the VHL gene. Sequences derived from amplified samples were compared to the wild-type VHL gene sequence (GeneBank Accession No. AF010238. Methylation status of the VHL gene was determined using VHL methylation-specific PCR primers after DNA bisulfite modification. In 4/10 (40% patients the VHL gene status differed between the P tumor and the M lesion. As expected, when the VHL gene was mutated in both the P tumor and M lesion, the mutation was identical. Further, while the VHL genotype differed between the primary tumor in different kidneys or multiple metastatic lesions in the same patient, the VHL germline genotype in the normal adjacent tissue was always wild-type irrespective of the VHL gene status in the P tumor. These results demonstrate for the first time that the VHL gene status can be different between paired primary and metastatic tissue in patients with CCRCC.

    Recently, novel molecular targeted agents markedly changed the treatment of renal cell carcinoma (RCC), with promising results. However, there is little understanding of how these agents affect immune cell populations in RCC, an immunogenic tumor. Therefore, we investigated the changes in the peripheral blood immune cells in 58 RCC patients during the first 4 weeks of treatment with sorafenib, sunitinib, everolimus, or temsirolimus and evaluated whether these changes were associated with clinical outcomes. The immunological parameters were the proportion of type-1 (Th1) and type-2 (Th2) T cells, regulatory T cells (Treg), mature dendritic cells, and the neutrophil-to-lymphocyte ratio (NLR). The changes in these immune cells varied with the agents and the clinical response, dichotomized by the median progression-free survival (PFS) time (PFS-short or PFS-long). A significant decrease in the Th1/Th2 ratio was seen after sunitinib treatment only in the PFS-short group, suggesting a shift toward Th2 that down-regulates host immunity. The NLRs indicative of the balance between host immunity and cancer-related inflammation were consistently lower in the PFS-long group than in the PFS-short group, suggesting that lower NLR is associated with better clinical response. Only sunitinib decreased NLR remarkably regardless of PFS status, which may favor anti-tumor immunity. When patients were dichotomized by the cutoff values, Th1/Th2 ratio was not associated with PFS in any targeted therapy, while lower pre-treatment NLR was associated with longer PFS in each targeted therapy. In addition, in RCC patients given sequential targeted therapy, those with a lower baseline NLR survived significantly longer compared with the counterparts. Moreover, those whose baseline NLR was sustained low during the initial therapy survived the longest. Our results suggest the diverse changes in host immune cells in RCC patients during targeted therapy. The changes in NLR during the early phase of

    Circulating tumor cells (CTCs) have emerged as promising tools for noninvasive cancer detection and prognosis. Most conventional approaches for capturing CTCs use an EpCAM-based enrichment strategy, which does not work well in cancers that show low or no expression of EpCAM, such as renal cell carcinoma (RCC). In this study, we developed a new set of cell surface markers including CA9 and CD147 as alternative CTC-capture antigens specifically designed for RCC patients. We showed that the expression of both CA9 and CD147 was prevalent in a RCC patient cohort (n=70) by immunohistochemical analysis, with both molecules in combination covering 97.1% of cases. The NanoVelcro platform combined with CA9-/CD147-capture antibodies demonstrated significantly higher efficiency for capturing both CTC-mimicking renal cancer cells and RCC CTCs in peripheral blood, compared to the conventional EpCAM-based method. Using immunofluorescence cytological validation at the single-cell level, we were able to identify bona fide CTCs in RCC patient blood following the well-accepted criteria in our CTC-capture system. We further demonstrated a significant association of CTC numbers as well as the CTC expression status of Vimentin, a mesenchymal marker, with disease progression, including pathologic features and clinical staging. These results provide new insights into developing novel, effective targets/approaches for capturing CTCs, making CTCs a valuable tool for improved cancer detection, prognosis and treatment in RCC.

    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.

    Vismodegib (GDC-0449, Genentech, USA), a small molecule inhibitor of the Hedgehog signalling pathway, has potent anti-tumour activity in advanced basal cell carcinoma (BCC). We report a case of a 67-year-old Australian man with metastatic BCC including pulmonary disease with malignant effusion who showed a dramatic complete response to vismodegib but subsequently experienced a recurrence of pulmonary disease, indicative of chemoresistance to vismodegib. This case is the first to illustrate chemoresistance in a patient with metastatic BCC, and demonstrates the need for closely monitoring metastatic BCC patients even after an apparently complete response.

    The aim of the present study was to determine the efficacy of immunotherapy with dendritic cells to elicit EBV-specific CTL-immunity in advanced cases of EBV-positive patients with nasopharyngeal carcinoma (NPC) and to determine the safety and toxicity of this preparation. Nine cases of histologically confirmed patients with NPC undergoing treatment with radiological therapy were enrolled in this study. Dendritic cells, generated in vitro from blood monocytes of patients were cultured and matured with cytokines and then infected with recombinant adenovirus vaccine containing EBV-latent membrane protein-2 (Ad-LMP2). On 9 days' cultivation of cells, the matured DCs were harvested, irradiated with 60Co and then injected intradermally to patients with NPC. The injections were performed 3 times totally. After immunization, the CTL responses were assayed by means of cytotoxicity and epitope-specific IFN-γ production. The results of this trial showed that all patients could tolerate this kind of treatment without any side effect, during which marked increase of LMP2-specific CTL-responses could be demonstrated in 5 patients of this group. And the level of IgA/VCA antibody decreased in 8 of 9 patients, thus accounting for a better prognosis for these patients. All patients will be followed up for another one year. At least, the present work shows that intradermal vaccination with autologous DCs infected with recombinant Ad-LMP2 adenovirus is a safe procedure in NPC patients, in which this procedure can enhance the LMP2-specific CTL responses in patients. These data are encouraging to develop more effective vaccine strategies for the treatment of nasopharyngeal carcinoma.

    Full Text Available OBJECTIVE: To analyze the results of the treatment of transitional cell carcinoma (TCC of the bladder with radical cystectomy and determine which prognostic factors can be utilized as disease-free survival and cancer-specific survival independent variables. MATERIALS AND METHODS: Medical records of 113 patients submitted to radical cystectomy and bilateral iliac lymphadenectomy between 1993 and 2005 were reviewed. The risk factors analyzed were age, sex, pathological stage, tumor grade, presence of carcinoma in situ and the presence of lymph nodes involvement. RESULTS: After a mean follow-up of 31.7 ? 28.5 months, 46 patients (40.7% presented recurrence and 24 patients (21.2% died due to cancer. Only pathological stage and the lymph nodes involvement became independent variables for recurrence and survival. Patients with T4 stage presented 9.6 times the risk of recurrence of the disease when compared with stage T0 patients (p = 0.010 and the patients with lymph node involvement presented 2.5 times the risk of recurrence (p = 0.047 and 3.1 times the risk of death (p = 0.022 when compared to patients without lymph nodes involvement. CONCLUSIONS: Pathological stage and the involvement of lymph nodes represented more important prognostic variables, and in the presence of advanced stage tumors (T3/T4 and involvement of lymph nodes, the institution of adjuvant treatment should be considered.

    In this retrospective study the results of primary and salvage treatment of oropharyngeal carcinoma were evaluated. A total of 289 consecutive patients (103 females and 186 males) were included in the study. Most tumours originated in the tonsil area (58%) and comprised stages I 8%, II 19%, III 46% and IV 28%. The primary treatment was delivered with curative intent in 276 cases (96%). Of these, 266 received primary radiotherapy. The median radiation dose was 62 Gy, given as laterally opposed fields to the primary tumour and bilateral neck. Eight patients were treated with primary surgery and two with chemotherapy as part of a curatively intended treatment programme including radiotherapy. Six patients received palliative treatment, and seven were not treated at all. Out of 276 tumours treated with curative intent, 173 reappeared; 72% recurred in T position, 38% in N position, and 12% at distant metastatic sites, some in combination. Salvage surgery was possible in 52 patients, and 24 treatments were successful. Salvage radiotherapy or cryotherapy was used in 22 patients and 4 were controlled. For the entire group, the 5-year locoregional tumour control, disease-specific survival and overall survival rates were 38%, 44% and 31%, respectively. For patients treated with curative intent, clinical T- and N-stage, stage, tumour size, gender, age, and pretreatment haemoglobin were significant prognostic parameters in a univariate analysis. The Cox multivariate analysis showed that T-stage, N-stage and gender were independent prognostic factors. It is concluded that T-stage, N-stage and gender are significant independent prognostic factors. The primary control of the carcinoma in the T-position is crucial for overall success, but salvage surgery is found to have a favourable success rate in patients suitable for relapse treatment.

The aim of this study was to ascertain relationship between the urine concentrations KIM-1 and AQP-1 with tumor size, grade, pT stage and type of operation (radical or partial nephrectomy in patients with cRCC. Methods. Urinary concentrations of urinary KIM-1 (uKIM-1 and urinary AQP-1 (uAQP-1 were determined by commercially available ELISA kits. The analysis included 40 patients undergoing partial or radical nephrectomy for cRCC and 40 age- and sex-matched healthy adult volunteers. Results. The median preoperative concentrations of KIM-1 in the cRCC group [0.724 ± 1.120 ng/mg urinary creatinine (Ucr] were significantly greater compared with controls (healthy volunteers (0.210 ± 0.082 ng/mgUcr (p = 0.0227. Postoperatively, uKIM-1 concentration decreased significantly to control values (0.177 ± 0.099 ng/mgUcr vs 0.210 ± 0.082 ng/mgUcr, respectively. The size, grade and stage of tumor were correlated positively with preoperative uKIM-1 concentrations. Contrary to these results, concentrations of uAQP-1 in the cRCC group were significantly lower (0.111 ± 0.092 ng/mgUcr compared with the control group (0.202 ± 0.078 ng/mgUcr (p = 0.0014. Postoperatively, the concentrations of uAQP-1 increased progressively up to control values, approximately. We find no significant correlation between preoperative uAQP-1 concentrations and tumor size, grade and stage. Conclusion. uKIM-1 was found to be a reliable diagnostic marker of cRCC, based on its significantly increased values before and decreased values after the nephrectomy.

    The aim of this study was to evaluate the results of the initial and salvage treatment for hypopharyngeal carcinoma. The study was conducted in 1963 to 1991 and included 138 patients (38 females and 100 males). Most of the tumours originated in the piriform sinus (86%). Tumour stage distribution was T1: 20%, T2: 27%, T3: 37% and T4: 17% and nodal stage distribution was N0: 45%, N1: 25%, N2: 10%, and N3: 20%. Primary treatment was delivered with curative intent in 124 out of 138 cases. Treatment failure was noted in 98 patients, with 55% recurrence in T-position, 39% in N-position, and 14% at distant metastases sites. Salvage surgery was successful in 9 out of 32 patients. The overall 5-year locoregional tumour control, cause-specific and overall survival rates were 20%, 25% and 19%, respectively. Univariate actuarial analysis showed that T- and N-stage, clinical stage, tumour size and well-differentiated tumours were significant prognostic parameters. A Cox multivariate analysis showed that only the T- and N-stages were independent prognostic factors. In conclusion, the prognosis for advanced hypopharyngeal carcinoma is extremely poor and the meagre results with conventional radiotherapy alone indicate that other treatment modalities should be introduced in the management of this disease.

    Full Text Available Nonislet cell tumor hypoglycemia (NICTH is a rare but serious paraneoplastic syndrome in which a tumor secretes incompletely processed precursors of insulin-like growth factor-II (IGF-II, causing hypoglycemia. Here, we report an exceptional case of NICTH caused by nonfunctioning adrenocortical carcinoma in a 39-year-old male with recurrent hypoglycemia. The patient’s serum IGF-II/IGF-I ratio had increased to 27.8. The serum level of the IGF-II/IGF-I ratio was normalized after removal of the tumor, and the hypoglycemic attacks no longer occurred after the operation.

    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.

    Objective: To improve the preparation of adherent lymphokine-activated killer (A-LAK) cells and study the synergistic anti-tumor effect of phenylacetate (PA) and A-LAK cells. Methods:\tA-LAK cells were obtained from peripheral blood mononuclear cells (PBMC) of patients with hepatocellular carcinoma (HCC) by using L-phenylalanine methyl ester (PME) to deplete immunosuppressive monocytes. The proliferation of SMMC7721 cell line treated with PA was studied. A-LAK cells were treated with the supernatant of SMMC7721 cells which had been pretreated with PA and the changes of the proliferation and anti-tumor activity of A-LAK cells were investigated. Results: The expansion of A-LAK cells was significantly higher than that of non-adherent LAK (NA-LAK) cells as well as regular LAK cells. The growth of SMMC7721 cells was significantly suppressed by PA. The supernatant of cultured tumor cells intensively suppressed the proliferation and cytotoxicity of A-LAK cells, but the suppressive effect of supernatant treated with PA previously was decreased. Conclusion: A-LAK cells could be simply prepared by using PME, and showed a synergistic anti-tumor effect with the combination of PA.

    2016-06-01

    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.

    AIM: To evaluate the correlation between serum vascular cellular adhesion molecule-1 (VCAM-1) levels and clinicopathological features in patients with hepatocellular carcinoma (HCC).METHODS: Ninety-six patients who underwent HCC resection were recruited in the study. Preoperative serum levels of soluble VCAM-1 were measured by enzyme-linked immunosorbent assay.RESULTS: Serum VCAM-1 level in HCC patients was inversely correlated with platelet count (r=-0.431, P<0.001)and serum albumin level (r=-0.279, P<0.001), and positively correlated with serum bilirubin level (r=0.379, P<0.001).Serum VCAM-1 level was not associated with tumor characteristics such as tumor size, venous invasion,presence of microsatellite nodules, tumor grade and tumor stage. Serum VCAM-1 level was significantly higher in HCC patients with cirrhosis compared with those without cirrhosis (median 704 vs 546 ng/mL, P<0.001). Furthermore, a significantly better disease-free survival was observed in HCC patients with low VCAM-1 level (P=0.019).CONCLUSION: Serum VCAM-1 level appears to reflect the severity of underlying chronic liver disease rather than the tumor status in HCC patients, and low preoperative serum VCAM-1 level is predictive of better disease-free survival after surgery.

    We sought to investigate the association of preoperative fibrinogen levels with clinicopathologic outcomes after surgical treatment of nonmetastatic renal cell carcinoma. We reviewed the records of 1511 patients who had their fibrinogen levels measured preceding surgery. The associations between preoperative fibrinogen level and risk of adverse clinicopathologic outcomes were tested using the multivariate logistic regression and multiple Cox-proportional hazards model, respectively. Based on plasma fibrinogen levels, we stratified the patients into 2 groups with a cut-off value of 328  mg/dL. Kaplan-Meier analysis showed significantly inferior survival outcomes in progression-free (P fibrinogen level (≥328  mg/dL) was significantly related to a higher Fuhrman grade (hazard ratio [HR] 1.374, P = 0.006) and a larger tumor size (≥7  cm) (HR 2.364, P fibrinogen level is a significant predictor for poor disease progression (HR 1.857, P fibrinogen levels were significantly associated with poor pathological features and worse survival outcomes in patients with nonmetastatic renal cell carcinoma after surgical treatment. Further evaluations such as prospective randomized trials are needed to understand the underlying mechanism for these associations.

    Paget's disease of the bone, historically known as osteitis deformans, is an uncommon disease typically affecting individuals of European descent. Patients with Paget's disease of the bone are at increased risk for primary bone neoplasms, particularly osteosarcoma. Many cases of metastatic disease to pagetic bone have been reported. However, renal cell carcinoma metastasized to pagetic bone is extremely rare. A 94-year-old male presented to the emergency department complaining of abdominal pain. A computed tomography scan of the abdomen demonstrated a large mass in the right kidney compatible with renal cell carcinoma. The patient was also noted to have Paget's disease of the pelvic bones and sacrum. Within the pagetic bone of the sacrum, there was an enhancing mass compatible with renal cell carcinoma. A subsequent biopsy of the renal lesion confirmed renal cell carcinoma. Paget's disease of the bone places the patient at an increased risk for bone neoplasms. The most commonly reported sites for malignant transformation are the femur, pelvis, and humerus. In cases of malignant transformation, osteosarcoma is the most common diagnosis. Breast, lung, and prostate carcinomas are the most common to metastasize to pagetic bone. Renal cell carcinoma associated with Paget's disease of the bone is very rare, with only one prior reported case. Malignancy in Paget's disease of the bone is uncommon with metastatic disease to pagetic bone being extremely rare. We report a patient diagnosed with concomitant renal cell carcinoma and metastatic disease within Paget's disease of the sacrum. Further research is needed to assess the true incidence of renal cell carcinoma associated with pagetic bone.

    Case: A 63-year-old male presented with unintentional weight loss of 20 pounds over a 4-month duration. He reported loss of appetite, intermittent post-prandial nausea, bloating and early satiety. He also complained of dyspepsia and had been treated for reflux during the previous 2 years. He denied vomiting, dysphagia, odynophagia, abdominal pain, melena, hematochezia, or alterations in bowel habits. Additionally, he denied fevers, night sweats, cough, or dyspnea. He quit smoking 25 years ago, and denied alcohol use. His past medical history was significant for basal cell carcinoma treated with local curative therapy and he was without recurrence on surveillance. Pertinent family history included a paternal uncle with lung cancer at the age of 74. Physical examination was unremarkable except for occult heme-positive stools. Laboratory evaluation revealed elevated liver enzymes (ALT-112, AST-81, AlkPhos-364). CT scan of the chest, abdomen and pelvis showed diffuse heterogeneous liver with extensive nodularity, raising the concern for metastases. Serum tumor-markers: PSA, CEA, CA 19-9, and AFP were all within normal limits. Screening colonoscopy was normal, but esophagogastroduodenoscopy revealed a malignant-appearing ulcerative lesion involving the gastro-esophageal junction and gastric cardia. Pathology confirmed an invasive gastric large cell neuroendocrine carcinoma. Ultrasound-guided fine needle aspiration of a hepatic lesion revealed malignant cells with cytologic features consistent with large-cell type carcinoma and positive immunostaining for synaptophysin favoring neuroendocrine differentiation. A PET-CT demonstrated intense diffuse FDG uptake of the liver, suggesting diffuse hepatic parenchymal infiltration by tumor. There were multiple foci of intense osseous FDG uptake with corresponding osteolytic lesions seen on CT scan. The remaining intra-abdominal and intra-thoracic structures were unremarkable. The patient will receive palliative systemic therapy

    Full Text Available Abstract Background Besides being the effectors of native anti-tumor cytotoxicity, NK cells participate in T-lymphocyte responses by promoting the maturation of dendritic cells (DC. Adherent NK (A-NK cells constitute a subset of IL-2-stimulated NK cells which show increased expression of integrins and the ability to adhere to solid surface and to migrate, infiltrate, and destroy cancer. A critical issue in therapy of metastatic disease is the optimization of NK cell migration to tumor tissues and their persistence therein. This study compares localization to liver metastases of autologous A-NK cells administered via the systemic (intravenous, i.v. versus locoregional (intraarterial, i.a. routes. Patients and methods A-NK cells expanded ex-vivo with IL-2 and labeled with 111In-oxine were injected i.a. in the liver of three colon carcinoma patients. After 30 days, each patient had a new preparation of 111In-A-NK cells injected i.v. Migration of these cells to various organs was evaluated by SPET and their differential localization to normal and neoplastic liver was demonstrated after i.v. injection of 99mTc-phytate. Results A-NK cells expressed a donor-dependent CD56+CD16+CD3- (NK or CD56+CD16+CD3+ (NKT phenotype. When injected i.v., these cells localized to the lung before being visible in the spleen and liver. By contrast, localization of i.a. injected A-NK cells was virtually confined to the spleen and liver. Binding of A-NK cells to liver neoplastic tissues was observed only after i.a. injections. Conclusion This unique study design demonstrates that A-NK cells adoptively transferred to the liver via the intraarterial route have preferential access and substantial accumulation to the tumor site.

    Purpose: When associated with radiotherapy the monoclonal antibodies such as cetuximab might be exacerbate skin toxicity. The aim of this study was to retrospectively analyze acute dermatological toxicity in ten consecutive patients with locally advanced head and neck squamous cell carcinoma treated from march 2008 to May 2009 according to Bonner protocol. Patients and methods: We have treated with radiotherapy and cetuximab ten patients with locally advanced head and neck squamous cell carcinoma of the oropharynx, hypopharynx, larynx or oral cavity, stage 3-4B and non metastatic. All our patients were 3D planned and scheduled for conventional fractionation 70 Gy/35 fractions over 47 days, five days weekly. Uninvolved neck received 50 Gy and gross nodal disease received 70 Gy as the primary tumor. Cetuximab was administered one week before radiotherapy at a loading dose of 400 mg per square meter of body surface area over 120 minutes, followed by weekly 60 minutes infusions at 250 mg per square meter for the duration of radiotherapy. Results: In eight patients (80%) grade 3 radiation dermatitis occurred as early as with 28 Gy at a median dose of 42 Gy (range 28-60 Gy). the median radiotherapy dose was 6 Gy with an overall treatment time of 57.7 days (range 41-70 days). were administered 78 cycles of cetuximab, one patient discontinued after five cycles due to infusion reactions. There was no correlation between toxicity and acne-like rash due to cetuximab. Conclusion: Our results albeit in disagreement with the original study are rather similar with the experience of other European centers that encounter grade 3-4 radiation dermatitis in 49% of their patients or Australian centers that reported 79% of same degree of toxicity.

    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.

    AIM: TO investigate the influence of autologous cytokineinduced killer (CIK) cells on the phenotypes of CIK effector cells, peripheral T lymphocyte subsets and dendritic cell subsets in patients with primary hepatocellular carcinoma (HCC).METHODS: Peripheral blood mononuclear cells (PBMC)were collected by a blood cell separator from 13 patients with HCC, then expanded by priming them with interferongamma (IFN-γ) followed by monoclonal antibody (mAb)against CD3 and interleukin-2 (IL-2) the next day. The phenotypic patterns of CIK cells were characterized by flow cytometry on d 0, 4, 7, 10, 13 and 15 of incubation,respectively. Then, 5 mL of venous blood was obtained from HCC patients before or 8-10 d after CIK cells were transfused into patients to assess the influence of CIK cells on the percentages of effector cells, and proportions of DC1 or DC2in peripheral blood by flow cytometry.RESULTS: After two weeks of in vitro incubation, the percentages of CD3+CD8+, CD3+CD56+, and CD25+ cells increased significantly from 33.5±10.1%, 7.7±2.8%, and 12.3±4.5% to 36.6±9.0% (P<0.05), 18.9±6.9% (P<0.01),and 16.4±5.9% (P<0.05), respectively. However, the percentages of CD3+CD4+ and NK cells had no significant difference. The percentages of CD3+ and CD3+CD8+ cells were kept at high levels during the whole incubation period, but those of CD25+, and CD3+CD56+ cells began to decrease on d 7 and 13, respectively. The proportions of type Ⅰ dendritic cell (DC1) and type Ⅱ dendriticcell (DC2) subsets increased from 0.59±0.23% and 0.26±0.12% before CIK cell therapy to 0.85±0.27% and 0.43±0.19% (all P<0.01) after CIK cell transfusion, respectively. The symptoms and characteristics of HCC patients were relieved without major side effects.CONCLUSION: Our results indicated that autologous CIK cells can efficiently improve the immunological status in HCC patients, and may provide a potent approach for HCC patients as the adoptive immunotherapy.

    Squamous cell carcinoma (SCC) is a relatively common, malignant neoplasm of dogs and cats that can arise in a variety of locations. The gross appearance of SCC can be variable and nonspecific, so definitive diagnosis requires microscopic examination of the tissue (cytology or histology). Several treatment modalities exist, but surgical excision, if possible, is regarded as the best treatment option. Early diagnosis and treatment of SCC are key because small, early-stage tumors are the most amenable to treatment and carry the best prognosis.

    To explore the potential of tumor-specific DNA as a biomarker for head and neck squamous cell carcinomas (HNSCC), we queried DNA from saliva or plasma of 93 HNSCC patients. We searched for somatic mutations or human papillomavirus genes, collectively referred to as tumor DNA. When both plasma and saliva were tested, tumor DNA was detected in 96% of 47 patients. The fractions of patients with detectable tumor DNA in early- and late-stage disease were 100% (n = 10) and 95% (n = 37), respectively. When segregated by site, tumor DNA was detected in 100% (n = 15), 91% (n = 22), 100% (n = 7), and 100% (n = 3) of patients with tumors of the oral cavity, oropharynx, larynx, and hypopharynx, respectively. In saliva, tumor DNA was found in 100% of patients with oral cavity cancers and in 47 to 70% of patients with cancers of the other sites. In plasma, tumor DNA was found in 80% of patients with oral cavity cancers, and in 86 to 100% of patients with cancers of the other sites. Thus, saliva is preferentially enriched for tumor DNA from the oral cavity, whereas plasma is preferentially enriched for tumor DNA from the other sites. Tumor DNA in saliva was found postsurgically in three patients before clinical diagnosis of recurrence, but in none of the five patients without recurrence. Tumor DNA in the saliva and plasma appears to be a potentially valuable biomarker for detection of HNSCC.

    BACKGROUND: Resection of the primary tumor followed by sentinel node biopsy (SNB) for the clinically N0 patient has been implemented in our Head and Neck University Center. The purpose of this study was to report on the outcome for patients with negative SNB. METHODS: From April 2007 to October...... 2009, 53 consecutive SNB-negative patients with oral cavity squamous cell carcinoma (SCC) T1 to T2 were accrued. Follow-up was done continuously with the most recent examination in October 2011. The location of the sentinel lymph nodes was determined using dynamic and planar lymphoscintigraphy...... and single photon emission CT (SPECT)-CT. Intraoperatively, a hand-held gamma probe was applied. The harvested sentinel lymph nodes underwent histopathologic examination using step-serial sectioning at 150-μm intervals and immunohistochemistry. In the follow-up period, we observed and examined the SNB...

    Full Text Available We report the case of a 64-year-old ex-smoker with metastatic poorly differentiated squamous cell carcinoma (SCC of the lung and an epidermal growth factor receptor (EGFR mutation in exon 21 (p.L858R who achieved prolonged clinical benefit from treatment with an EGFR tyrosine kinase inhibitor (TKI. The initial diagnosis of SCC of the lung obtained by bronchoscopic biopsy was based on immunohistochemical staining only with positivity for cytokeratin (CK 5/6 and p63 because morphological diagnosis was not possible. Patients with non-small cell lung cancer (NSCLC, not otherwise specified (NOS favouring SCC are usually not tested for the presence of EGFR mutations, and therefore may not receive EGFR TKI therapy. A bronchoscopic rebiopsy showed small nests of undifferentiated tumour cells with weak immunoreactivity of some tumour cells for CK5/6, p63 and no positivity of some tumour cells for thyroid transcription factor-1. These findings suggested a mixed squamous/glandular immunophenotype that has been missed at the initial biopsy. Our clinical case illustrates the problem of tumour heterogeneity encountered in small bronchoscopic biopsies and the difficulties of evaluating the histological subtype in poorly differentiated carcinomas. Initial bronchoscopy should be performed by an experienced pulmonologist who attempts to obtain sufficient material from different areas of the tumour. In the era of targeted therapy, a remote smoking history in a patient with NOS favouring SCC should also lead to EGFR mutation testing to allow highly effective therapy to be offered to mutation-positive patients.

    Sunitinib represents a reasonable therapeutic option for first-line treatment of poor-risk metastatic renal cell carcinoma and the treatment should aim at the delicate balance between managing side effects to improve the toxicity profile and patient compliance to treatment while maintaining anticancer efficacy. Achievement of a complete response, although rare, is possible, even in poor-risk patients. Treatment discontinuation represents a viable alternative for both tumour biology and patients' quality of life. To date, no molecular markers have been identified with prognostic and/or predictive value for guiding therapeutic decisions. Further research should aim at gaining in-depth knowledge of renal cell carcinoma biology for a tailored personalized therapy. We report a case of poor-risk metastatic renal cell carcinoma, with Von Hippel-Lindau loss of function, which achieved and maintained a complete remission after first-line therapy with sunitinib by using a reduced dosage and a modified schedule of treatment.

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

    Full Text Available Follicular cell-derived well-differentiated thyroid cancer, papillary (PTC and follicular thyroid carcinomas (FTC compose 95% of all thyroid malignancies. Familial follicular cell-derived well-differentiated thyroid cancers contribute to 5% of those cases. These familial follicular cell derived carcinomas or non-medullary thyroid carcinomas (NMTC divide into two clinical-pathological groups. One group, syndromic-associated, composed by predominately non-thyroidal tumors, is comprised of Pendred syndrome, Warner syndrome, Carney complex type 1, PTEN-hamartoma tumor syndrome (Cowden disease; PHTS, familial adenomatous polyposis (FAP/Gardner syndrome. Additionally other less established links correlated to the development of follicular cell-derived tumors have also included Ataxia-teleangiectasia syndrome, McCune Albright syndrome, and Peutz-Jeghers syndrome. The subsequent group encompasses syndromes typified by non-medullary thyroid carcinomas or NMTC, as well as, pure familial (f PTC with or without oxyphilia, fPTC with multinodular goiter and fPTC with papillary renal cell carcinoma. This heterogeneous group of diseases has not a established genotype-phenotype correlation as the well-known genetic events identified in the familial C-cell-derived tumors or medullary thyroid carcinomas (MTC. Clinicians should be have the knowledge to identify the likelihood of a patient presenting with thyroid cancer having an additional underlying familial syndrome stemming from characteristics through morphological findings that would alert the pathologist to have the patient undergo subsequent molecular genetics evaluations. This review will discuss the clinical and pathological findings of the patients with familial papillary thyroid carcinoma, such as familial adenomatous polyposis, Carney complex, Werner syndrome, and Pendred syndrome and the heterogeneous group of familial papillary thyroid carcinoma.

    Full Text Available Abstract Background The oncogene CDC25B phosphatase plays an important role in cancer cell growth. We have recently reported that patients with esophageal squamous cell carcinoma (ESCC have significantly higher serum levels of CDC25B autoantibodies (CDC25B-Abs than both healthy individuals and patients with other types of cancer; however, the potential diagnostic or prognostic significance of CDC25B-Abs is not clear. The aim of this study is to evaluate the clinical significance of serum CDC25B-Abs in patients with ESCC. Methods CDC25B autoantibodies were measured in sera from both 134 patients with primary ESCC and 134 healthy controls using a reverse capture enzyme-linked immunosorbent assay (ELISA in which anti-CDC25B antibodies bound CDC25B antigen purified from Eca-109 ESCC tumor cells. The clinicopathologic significance of CDC25B serum autoantibodies was compared to that of the tumor markers carcinoembryonic antigen (CEA, squamous cell carcinoma antigen (SCC-Ag and cytokeratin 19 fragment antigen 21-1(CYFRA21-1. Results Higher levels of CDC25B autoantibodies were present in sera from patients with ESCC (A450 = 0.917, SD = 0.473 than in sera from healthy control subjects (A450 = 0.378, SD = 0.262, P 450 greater than the cut-off value of 0.725. Relatively few patients tested positive for the tumor markers CEA, SCC-Ag and CYFRA21-1 (13.4%, 17.2%, and 32.1%, respectively. A significantly higher number of patients with ESCC tested positive for a combination of CEA, SCC, CYFRA21-1 and CDC25B-Abs (64.2% than for a combination of CEA, SCC-Ag and CYFRA21-1 (41.0%, P P P = 0.001, log-rank. In the N1 subgroup, the cumulative five-year survival rate of CDC25B-seropositive patients was 13.6%, while that of CDC25B-seronegative patients was 54.5% (P = 0.040, log-rank. Conclusions Detection of serum CDC25B-Abs is superior to detection of the tumor markers CEA, SCC-Ag and CYFRA21-1 for diagnosis of ESCC, and CDC25B-Abs are a potential prognostic

    Full Text Available Esophageal carcinomas have been shown to express Fas ligand (FasL and down-regulate Fas to escape from host immune surveillance. Circulating soluble FasL (sFasL has been suggested to provide protection from Fas-mediated apoptosis. The aim of this study was to assess serum sFasL levels in esophageal cancer. The pretreatment levels of sFasL in the serum of 100 patients with esophageal squamous cell cancer and 41 healthy volunteers were determined by ELISA. Probability of survival was calculated according to the method of Kaplan-Meier. The prognostic influence of high and low level of sFasL was analyzed with the log-rank test. The mean serum level of sFasL in patients with esophageal cancer was significantly higher than that in healthy donors (1.567+/-1.786 vs 0.261+/-0.435, p<0.0001. The levels of serum sFasL were significantly higher in advanced stages (II vs IV p<0.034; III vs IV p<0.041; except II vs III p=0.281, patients with lymph node (N0 vs N1 p<0.0389 or distant (M0 vs. M1 p<0.0388 metastases and significantly lower in patients with well differentiated tumors (G1 vs G2 p<0.0272. The serum levels of soluble FasL were not related to gender, age, tumor size, T-stage, tobacco smoking and history of chronic alcohol intake. The survival difference between pretreatment high and low level of sFasL in surgery and chemio- and/or radiotherapy group was not statistically significant (p=0.525; p=0.840. Our results indicate that elevated serum sFasL levels might be associated with a disease progression in patients with esophageal squamous cell carcinoma.

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

    The presence of IL-1 in human cancers is associated with aggressive tumor biology but its prognostic value is unknown. We studied whether IL-1α expression is a prognostic marker of distant metastasis in patients with head and neck squamous cell carcinoma (HNSCC). IL-1α mRNA and protein levels were determined in tumor samples and cancer cell lines using RT-PCR and ELISA. The effects of constitutive IL-1α expression by tumor lines were characterized. IL-1α mRNA and protein secretion were higher in tumor samples from patients who later developed distant metastasis than in patients who did not. By using distant metastasis as a dependent variable, patients were classified into two categories of IL-1α transcript-levels. The high-IL-1α group had a significantly lower five-year distant metastasis-free survival than the low-IL-1α group [70.0% (CI 95%: 55.9-84.1%) vs 94.7% (CI 95%:90.2-99.2%)]. When IL-1α transcript-levels were combined with clinical factors related to tumor metastasis, the predictive power of the model increased significantly. Additionally, transcript levels of IL-1α correlated significantly with those of the IL-1 family genes and genes related to the metastatic process. IL-1 treatment of microvascular endothelial cells increased adhesion of HNSCC cells but no differences were found based on constitutive IL-1α expression by tumor cells. Nevertheless, IL-1α produced by tumor cells effectively increased their transmigration across the endothelium. We found a significant relationship between IL-1α expression and development of distant metastasis in HNSCC patients. IL-1α expression could help to define a subset of patients at high risk of distant metastasis who could benefit from adjuvant treatment. PMID:26460957

    Full Text Available Synchronous bilateral renal cell carcinoma occurs in 1.4 % of cases. The probability of bilateral adrenal metastases from renal cell carcinoma is less than 0.5 %. The clinical observation presents a case of synchronous bilateral renal cell carcinoma and simultaneous metastatic involvement of both adrenal glands. A 55‑year-old male patient was adm tted with the signs of hematuria and anemia to the Unit of Urology, Clinic of General Surgery, Siberian State Medical University. He was found to have synchronous bilateral renal cell carcinoma and simultaneous bilateral adrenal involvement. Sequential surgical treatment – radical nephrectomy (with adrenal gland removal on the right side and, after 3 months, adrenalectomy and kidney resection on the left side were performed. All the organs removed displayed tumors that proved to be renal cell carcinomas (a clear cell variant. There were lymph node metastases in the right-sided renal portal. Postoperatively, the investigators performed hormone replacement therapy for adrenal insufficiency, an immunotherapy cycle, three cycles of targeted therapy withsorafenib and sunitinib (at an interval of 0.5–2 years, and insulin therapy for new-onset diabetes mellitus. The duration of a follow-up was 6.2 years. When describing the case, the patient was alive and showed a generalized tumorous process with extensive tumor involvement of the solitary kidney. Sunitinib therapy was used.

    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.

    Background Many cancers adopt a metabolism that is characterized by the well-known Warburg effect (aerobic glycolysis). Recently, numerous attempts have been made to treat cancer by targeting one or more gene products involved in this pathway without notable success. This work outlines a transcriptomic approach to identify genes that are highly perturbed in clear cell renal cell carcinoma (CCRCC). Methods We developed a model of the extended Warburg effect and outlined the model using Cytoscape. Following this, gene expression fold changes (FCs) for tumor and adjacent normal tissue from patients with CCRCC (GSE6344) were mapped on to the network. Gene expression values with FCs of greater than two were considered as potential targets for treatment of CCRCC. Results The Cytoscape network includes glycolysis, gluconeogenesis, the pentose phosphate pathway (PPP), the TCA cycle, the serine/glycine pathway, and partial glutaminolysis and fatty acid synthesis pathways. Gene expression FCs for nine of the 10 CCRCC patients in the GSE6344 data set were consistent with a shift to aerobic glycolysis. Genes involved in glycolysis and the synthesis and transport of lactate were over-expressed, as was the gene that codes for the kinase that inhibits the conversion of pyruvate to acetyl-CoA. Interestingly, genes that code for unique proteins involved in gluconeogenesis were strongly under-expressed as was also the case for the serine/glycine pathway. These latter two results suggest that the role attributed to the M2 isoform of pyruvate kinase (PKM2), frequently the principal isoform of PK present in cancer: i.e. causing a buildup of glucose metabolites that are shunted into branch pathways for synthesis of key biomolecules, may not be operative in CCRCC. The fact that there was no increase in the expression FC of any gene in the PPP is consistent with this hypothesis. Literature protein data generally support the transcriptomic findings. Conclusions A number of key genes have

    Full Text Available Tubulocystic renal cell carcinoma (TCRCC is a rare variant of renal cell carcinoma, which has distinct histology but there is some controversy about its association with papillary renal cell carcinoma (PRCC and cell of origin in literature. We report an 18-year-old girl with the rare TCRCC of kidney associated with PRCC with metastases to the para-aortic nodes. The patient presented with hematuria and a right renal mass with enlarged regional nodes for which a radical nephrectomy with retroperitoneal lymph node dissection was done. On gross examination, a solid cystic lesion involving the lower pole and middle pole of the kidney measuring 12x9x9 cm was seen along with an additional cystic lesion in upper pole of kidney. Microscopically the main tumor showed the typical histology of a tubulocystic carcinoma with multiple cysts filled with secretions lined by variably flattened epithelium with hobnailing of cells. The mass in the upper pole was a high-grade PRCC and the nodal metastases had morphology similar to this component. To conclude, at least a small but definite subset of TCRCC is associated with PRCC, and cases associated with PRCC do seem to have a higher propensity for nodal metastasis as in the case we report.

    Directory of Open Access Journals (Sweden)

    Annalisa Guida

    2016-07-01

    Full Text Available Agents targeting the vascular endothelial growth factor (VEGF/VEGF receptor (VEGFR pathway, as well as mammalian target of rapamycin (mTOR inhibitors have revolutionised the therapeutic landscape of metastatic renal cell carcinoma (mRCC in the past decade, greatly improving the survival rates of these patients. However, translating results of registrative Phase III trials into everyday clinical practice is often troublesome, since real-world patients are completely different from those enrolled in randomised controlled Phase III trials. Prospective data on active oncological treatments in mRCC patients on dialysis are dramatically lacking. This literature review summarises and critically comments on available data relative to mRCC patients on dialysis receiving either VEGF/VEGFR-targeting agents, or mTOR inhibitors. Although prospective studies would definitely be warranted in these specific patient populations, all the available data suggest that mRCC patients on dialysis have the same outcome, both in terms of efficacy and safety, as mRCC patients with normal or marginally impaired kidney function, when treated with VEGF/VEGFR-targeting agents and/or mTOR inhibitors.

    There has, to our knowledge, been no previous report of changes in the prevalence and outcomes of treatment of HPV-positive (+) oropharyngeal squamous cell carcinoma (SCC) in New Zealand. We identified all affected patients in the greater Wellington region between 1 January 1994 and 30 November 2014 from the New Zealand Cancer Registry. Their personal details, characteristics of their tumours, treatment, complications, and outcomes were collected retrospectively from their casenotes and the New Zealand Death Registry, followed by p16 immunohistochemical staining. Of the 161 patients included, 131 (81%) were men. p16 immunohistochemical staining was done routinely in 13 patients during investigations, and retrospectively for 135 patients. The proportion of p16+ oropharyngeal SCC increased from 24% during 1994-1999, to 76% during 2009-2014 (pp16+ than in non-Europeans (67% compared with 44%, p=0.036). Patients with p16+ disease were younger (mean (SD) 56 (10) compared with 66 (9) years, pp16+ disease (65/86 (76%) compared with 15/49 (31%), p=0.000). Interestingly, all-cause age at death was younger in p16+ patients (62 (11.1) compared with 71 (11.2) years, p=0.001). The prevalence of p16+ oropharyngeal SCC had tripled in this population between 1994 and 2014, and affected patients have distinct characteristics and outcomes of treatment.

    Abstract Introduction: Currently, the options are limited for the treatment of patients who have failed 2 lines of chemotherapy for advanced lung squamous cell carcinoma (SCC). Recently, nivolumab, a fully human IgG4 programmed death 1 immune checkpoint inhibitor antibody, was approved to treat patients with advanced stage, relapsed/refractory lung SCC. Although nivolumab has demonstrated antitumor activity with survival benefit in Caucasian patients, its efficacy in Asian patients is unknown. Case Report: In this report, we describe a Chinese patient with relapsed advanced stage lung SCC who had an excellent response to nivolumab after only 2 doses without any adverse effects. Immunohistochemical analysis indicated the tumor was stained positive for programmed death-ligand 1. Conclusion: To our knowledge, this is the first report of satisfactory efficacy of short-term nivolumab treatment in a Chinese patient with relapsed advanced-stage lung SCC. Further clinical trials in Asian countries are needed to test whether nivolumab immunotherapy is a safe and effective treatment for Asian patients with lung SCC. PMID:27749580

    Full Text Available Objective To analyze the clinical efficacy and safety of sunitinib combined with autologous dentritic cell (DC and cytokine induced killer cell (CIK for patients suffering from metastatic renal cell carcinoma (mRCC. Methods Clinical data of 27 mRCC patients treated with sunitinib combined with autologous DC and CIK were reviewed retrospectively. Efficacy, quality of life, immunology and safety of this treatment were evaluated. Results Follow-up time ranged from 4 to 25 months. Out of all the patients, sunitinib was reduced in 1 and discontinued in 2 due to side effects; 1 patient quit for personal reasons; 14 patients developed progressive disease. The progression-free survival (PFS was 4 to 19.5 months. Ten patients died from tumor, the overall survival time (OS was 6 to 21 months. The median PFS was 16 months (95%CI 12.5-19.5. The OS was not achieved. The efficacy was evaluated according to Response Evaluation Criteria in Solid Tumors (RECIST. All the patients received treatment over 1 cycle. After one course of treatment, among 27 patients, 0 had complete remission (CR, 4 had partial remission (PR, 17 had stable disease (SD, and 6 had progressive disease (PD. The overall objective remission rate (ORR and disease control rate (DCR were 14.8% (4/27 and 77.8% (21/27, respectively. Sunitinib and autologous transfusion of DC and CIK improved the immune function and quality of life. The major adverse events were fatigue, hand-foot syndrome, hypertension, hypothyroidism, thrombocytopenia, neutropenia and fever. Most of the adverse events were ameliorated by supportive treatment or dose reduction. Conclusions  Sunitinib combined with autologous DC and CIK may be beneficial in the treatment of mRCC with acceptable toxic reactions, and it may be considered as a new approach for the comprehensive treatment of RCC.

    Purpose: To evaluate the influence of preoperative and palliative embolization of renal cell carcinomas on survival, intra- and post-operative procedures, and symptom control for palliative and preoperative indications. Materials and Methods: 56 patients who underwent renal cell carcinoma embolization from 1981 to 1999 were included in this retrospective study. Results: 24 women and 32 men were included (mean age 59.4 years). Complete follow-up data was available for 49 patients. 42 patients underwent preoperative embolization at different tumor stages (pT1: 1 patient, pT2: 6, pT3 a: 4, pT3 b: 19, pT3 c: 2, pT4: 5). 14 patients underwent palliative embolization (T1: 0 patients, T2: 5, T3: 4, T4: 4). Indications for preoperative embolization were bleeding of the renal tumor in 6 cases - non-recurrent bleeding reported, flank pain in 4 patients - 3 of 4 patients had no further symptoms, recurrent tumor embolization in 1 patient, and 2 patients who wanted to be treated without symptoms. The mean survival time of preoperative embolized patients was 3.1{+-}5.11 years with a 5-year survival rate of 50%. The mean survival time of palliative embolized patients was 0.67{+-}0.76 years with initial metastases (n=7) and 2.33{+-}2.40 without metastases (n=6). Conclusion: Palliative embolization of renal cell carcinomas is a safe therapeutic method to treat advanced renal cell carcinomas allowing control of symptoms such as hematuria and flank pain in more than 90% of our cases. Preoperative embolization yields a patient survival time comparable to that of patients at earlier tumor stages and is dependent on the metastases. (orig.)

    This study aimed to identify a potential association of the number of involved extraspinal organs with the survival of patients with metastatic spinal cord compression (MSCC) from renal cell carcinoma. Data of 69 patients irradiated for MSCC from renal cell carcinoma were retrospectively evaluated for survival. The prognostic value of the number of involved extraspinal organs and eight additional factors were investigated. These additional factors included age, gender, performance status, number of involved vertebrae, interval from cancer diagnosis to radiotherapy (RT) of MSCC, ambulatory status prior to RT, time developing motor deficits, and the fractionation regimen (30 Gy in 10 fractions vs. higher doses). The 6-month survival rates for involvement of 0, 1, and ≥ 2 extraspinal organs were 93, 57, and 21 %, respectively (p < 0.001). In the multivariate analysis, the number of involved extraspinal organs maintained significance (risk ratio 2.65; 95 % confidence interval 1.64-4.52; p < 0.001). The interval from cancer diagnosis to RT of MSCC (p = 0.013) and ambulatory status prior to RT (p = 0.002) were also independent predictors of survival. The number of involved extraspinal organs is a new prognostic factor of survival in patients with MSCC from renal cell carcinoma and should be considered in future clinical trials. (orig.)

    Full Text Available Merkel cell carcinoma (MCC of the skin is a rare, aggressive, malignant neuroendocrine neoplasm. The tumor classically demonstrates positive immunohistochemistry (IHC staining for chromogranin A(ChrA, cytokeratin 20 (CK20, neuron specific enolase (NSE and/or achaete-acute complex-like 1 (MASH1. The newly identified Merkel cell polyomavirus (MCPyV has been found to be associated with most MCC cases. The primary histologic differential diagnoses of cutaneous MCC is small cell primary bronchogenic carcinoma (SCLC; moreover, both are of neuroendocrine origin. SCLC accounts for approximately 10-15% of all primary lung cancer cases; this histologic subtype is a distinct entity with biological and oncological features distinct from non-small cell lung cancer (NSCLC. In contradistinction to MCC, SCLC is classically IHC positive for cytokeratin 7 (CK7 and transcription factor (TTF-1. Similar to SCLC, MCC cell lines may be classified into two different biochemical subgroups designated as Classic and Variant. In our review and case report, we aim to emphasize the importance of a multidisciplinary approach to the approach to this difficult differential diagnosis. We also aim to comment about features of the cells of origin of MCC and SCLC; to summarize the microscopic features of both tumors; and to review their respective epidemiologic, clinical, prognostic and treatment features. We want to emphasize the initial workup study of the differential diagnosis patient, including evaluating clinical lymph nodes, a clinical history of any respiratory abnormality, and chest radiogram. If a diagnosis of primary cutaneous MCC is confirmed, classic treatment includes excision of the primary tumor with wide margins, excision of a sentinel lymph node, and computed tomography, positron emission tomography and/or Fluorine-18-fluorodeoxyglucose positron emission tomography scan studies

We aimed to assess the association between the baseline values and treatmentrelated modifications of total serum cholesterol (C, triglycerides (T, body mass index (BMI, fasting blood glucose level (FBG and blood pressure (BP levels and the outcome of patients treated with everolimus for mRCC.177 patients were included in this retrospective analysis. Time to progression (TTP, clinical benefit (CB and overall survival (OS were evaluated.Basal BMI was significantly higher in patients who experienced a CB (p=0,0145. C,T and C+T raises were significantly associated with baseline BMI (p=0.0412, 0.0283 and 0.0001. Median TTP was significantly longer in patients with T raise compared to patients without T (10 vs 6, p=0.030, C (8 vs 5, p=0.042 and C+T raise (10.9 vs 5.0, p=0.003. At the multivariate analysis, only C+T increase was associated with improved TTP (p=0.005. T raise (21.0 vs 14.0, p=0.002 and C+T increase (21.0 vs 14.0, p=0.006 were correlated with improved OS but were not significant at multivariate analysis.C+T raise is an early predictor for everolimus efficacy for patients with mRCC.

    The aim of the study was a determination of the levels of nitric oxide (NO) and its biological markers such as malonyldialdehyde (MDA) and nitrotyrosine in the serum of patients with squamous cell carcinoma (SCC) of the oral cavity and identification of the relationships between NO and those markers. These studies were performed on patients with SCC of the oral cavity before and after treatment. Griess reaction was used for the estimation of the total concentration of NO in serum. The nitrotyrosine level in serum was assessed with an enzyme-linked immunosorbent assay (ELISA) kit, and MDA level using a spectrophotometric assay. Higher concentrations of NO in blood serum were determined in patients with stage IV of the disease before treatment in comparison to the control group and patients with stages II and III of the disease. Moreover, higher concentrations of MDA and nitrotyrosine were determined in the serum of patients in all stages of the disease in comparison to healthy people. After treatment, lower concentrations of NO in the serum of patients with stage IV of the disease were observed in comparison to the amounts obtained prior to treatment. In addition, lower levels of nitrotyrosine in the serum of patients with all stages of the disease were recorded, whereas higher concentrations of MDA were determined in these patients in comparison to results obtained before treatment. The compounds formed with the contribution of NO, such as MDA and nitrotyrosine, may lead to cancer progression in patients with SCC of the oral cavity, and contribute to formation of resistance to therapy in these patients as well. Moreover, the lack of a relationship between concentrations of NO and MDA, and between NO and nitrotyrosine in serum suggests that the process of lipid peroxidation and nitration in patients with SCC does not just depend on NO.

However, little information is available on ZEB-1 expression in oral cavity squamous cell carcinoma (OSCC.Methods: The expression levels of ZEB-1 and E-cadherin were assessed by immunohistochemistry in a cohort of 120 patients with OSCC treated by curative operation, and then the correlations between ZEB-1 and E-cadherin expression and clinical factors were evaluated, including patient prognosis. Quantitative real-time polymerase chain reaction (qRT-PCR assays were performed to assess mRNA levels of ZEB-1 and E-cadherin in 20 matched OSCC specimens.Results: Patients were followed up for a median period of 66 months (range 8-116 months, and 5-year overall survival was 68.3%. Positive ZEB-1 and E-cadherin immunostaining reactivity was detected in 64 (53.3% and 53 (44.2% patients, respectively. There was a negative correlation between ZEB-1 expression and E-cadherin expression. In addition, overexpression of ZEB-1 was significantly associated with recurrence, lymph node metastasis, and pathologic grading of patients, loss of E-cadherin was significantly associated with lymph node metastasis and pathologic grading of patients. Univariate analysis showed that increased ZEB-1 expression, loss of E-cadherin expression, lymph node metastasis, recurrence, and pathology grade were prognostic factors. In multivariate analysis, increased ZEB-1 expression and recurrence remained independent prognostic factors. In particular

    Full Text Available Tumor responses in advanced basal cell carcinoma (BCC have been observed in clinical trials with vismodegib, a SMO antagonist. The result of SMO antagonism is inhibition Hedgehog Signaling Pathway (HHSP downstream target genes. HHSP inhibition has been shown to affect stem cells responsible for blood, mammary, and neural development. We report on our experience of treating two patients with advanced BCC participating. These two patients have had no new BCCs develop for at least 2.25 years. Both patients have been receiving ongoing daily treatment with vismodegib for greater than 2.75 years without experiencing any significant side effects. After prolonged continuous daily dosing with a SMO antagonist, we have not observed a significant alteration in hematologic parameters or physical abnormalities of the pectoral regions of two patients with advanced BCC.

    SPP1, PAI and caveolin-1 are known to be closely associated with tumor progression in several kinds of human tumors. This study aimed to investigate the expression of SPP1, PAI and caveolin-1 in oral squamous cell carcinoma (OSCC), and to evaluate their association with the prognosis in oral carcinoma. Immunohistochemical staining was used to examine the expression of SPP1, PAI and caveolin-1 in 17 normal oral mucosa, 6 oral epithelial dysplasia and 43 OSCC specimens by tissue microarrays. High expression of SPP1, PAI and caveolin-1 was found in OSCC patients, and SPP1 and PAI expression were significantly higher in OSCC than in normal oral mucosa. No significant correlations were found between SPP1, PAI and caveolin-1 expression and clinicopathological factors. Expression of SPP1, PAI and caveolin-1 was also not associated with overall survival. Moreover, SPP1 was closely correlated with PAI, caveolin-1 and Keap1, and PAI had significant correlations with caveolin-1, Keap1 and Nrf2, and caveolin-1 was associated with Keap1 by using the Pearson correlation coefficient test. Our findings suggest that overexpressed SPP1, PAI and caveolin-1 were linked to carcinogenesis and progression, and thus they may serve as potential prognostic factors in OSCC.

    Full Text Available Prostate cancer is the most common malignancy of men in the United States. Small-cell carcinoma (SCC, which typically presents as an aggressive lung malignancy, is a rare diagnosis within the setting of prostate cancer pathology. Due to its limited prevalence, little information regarding the treatment and prognosis of this disease in large populations is available. To date our current knowledge base is largely limited to case reports and retrospective case reviews. The mainstay of treatment for this particular histology most often involves a multimodality approach utilizing chemotherapy in conjunction with radiation therapy, androgen deprivation therapy, or prostatectomy. Here we present the case of an elderly 89- year-old Caucasian male who was diagnosed with SCC of the prostate. Despite proceeding with a course of definitive radiotherapy, the patient experienced rapid progression of disease and ultimately elected to discontinue radiation therapy and receive hospice care.

    The aims of this study were to clarify the effects of radiotherapy on haemostatic activity in patients with oral squamous cell carcinoma (SCC) and to investigate the differences in the clinical findings. The subjects were 61 patients with primary oral SCC (SCC group) who had undergone preoperative radiotherapy of 34.2{+-}7.2 Gy (mean{+-}SD). These patients were divided into early group (stage I and II) and advanced group (stage III and IV), and the region in the oral cavity. Before and after radiotherapy, activated partial thromboplastin time (APTT), fibrinogen, prothrombin fragment 1+2 (F1+2) and plasmin-{alpha}{sub 2} plasmin inhibitor complex (PAP) were measured. In SCC group, after the radiotherapy, APTT extended and PAP increased. In the early stage group, PAP increased and in the advanced group, there was the extension of APTT. The regional division of the patients, there was the extension of APTT in oral floor and lower gingiva groups. F1+2 in lower gingiva group increased, and PAP rose in tongue and buccal mucosa groups. These results indicate that irradiation affects blood coagulation fibrinolysis system in patients with oral SCC, but the amount of the activation differs by the clinical findings. (author)

    The aim of this study was to evaluate the demographic, clinical, and therapeutic characteristics and predictive factors of poor prognosis in patients with primary oral squamous cell carcinoma (OSCC) in Uruguay. Medical records of patients with the diagnosis of primary OSCC treated between 2000 and 2010 in Uruguayan public hospitals were selected. Data on demographic characteristics, risk factors, clinical features, treatment, and outcome were collected. Associations of independent variables with outcomes were assessed using Pearson chi-squared and Fisher's tests. Of 200 patients with OSCC, 79.4% were men (3.8:1 male:female ratio), with a mean age of 60.75 ± 11.26 years. Tobacco and alcohol consumption were reported by 85.3% and 63.5% of patients, respectively. The most commonly affected location was the tongue (42.5%), with lesions exhibiting ulcerous aspects in 87.9% of cases and pain at the time of diagnosis in 70.4% of cases. One hundred sixty-one (82.1%) patients had advanced-stage (III/IV) OSCC. Surgery was the most common treatment option, and the overall 5-year survival rate was 58.5%. Univariate analysis showed that the predictors of poor prognosis were clinical aspect, size, regional metastasis, clinical stage, and treatment. In Uruguay, OSCC is diagnosed late, which is associated with a low survival rate. Educational and preventive measures and investment to improve early diagnosis should be undertaken.

    Full Text Available Introduction: Squamous cell carcinoma (SCC is the most commonoral malignant neoplasm, affecting mainly men over 50 years, with themain risk factors of smoking and alcoholism. The incidence of thisneoplasm in young people under the age of 40 is rare (3 to 6% of cases. In these patients the course of the disease is even more aggressive, showing higher risk of cervical metastatization with unfavorable prognosis. Objective: The aim of this article was to describe a clinical case of aggressive cancer of the mouth and unfavorable development in a young patient, considering the use of marijuana and smoking as possible risk factors. Predisposing factors are discussed, as well as the literature review related to SCC in young people. Case report: It was reported a case of SCC of the mouth in a 21-year-old male patient, who was leukoderma, smoker and user of marijuana. The patient was diagnosed in very advanced stages of the disease and treated with concurrent chemotherapy and radiotherapy, due to the unresectable tumor, but he left the treatment during radiotherapy and evolved to death after two months of last contact. Conclusion: The case highlights the importance of early diagnosis of lesions of oral cancer, as well as the increase in prevention campaigns, focusing also young patients, users of marijuana.

The proportion of men and women was 72.3 % and 27.7 %, respectively; their ratio was 2.6:1. All the patients (100% underwent surgical treatment as nephrectomy or kidney resection for primary tumor. In the patients who had received radical treatment in different periods, the median relapse-free survival was 25.3 (0-187 months; the mean follow-up duration in the study was 33.2 (27.4–39.0 months. Out of the histological characteristics of a primary tumor, its Fuhrman grade was studied. Prior to initiation of mRCC therapy, Memorial Sloan Kettering Cancer Center (MSKCC prognosis groups were assessed; the patients were divided into good (n = 9 (19.1 %, interim (n = 28 (59.6 %, and bad (n = 10 (21.3 % prognosis groups. Their total somatic status was separately rated using the ECOG scale: 0, (n = 10 (21.3%, 1 (n = 24 (51.1 %, and 2, (n = 13 (27.6 %. The sites of metastases were as follows: the lung (n = 29, bones (n = 18, adrenals (n = 11, recurrence in the removed kidney bed (n = 10, and liver (n = 10. Multiple organ involvements were detected in 22 (46.8 % patients. There were more than 5 metastases in one organ in 18 (40.0 % patients and only 15 (33.3 % were found to have a single focus in one organ. Whether iCR might be used as a separate line treatment was studied. A comparative analysis was made between 2 groups of

    The dual pathway inhibitor rigosertib inhibits phosphoinositide 3-kinase (PI3K) pathway activation as well as polo-like kinase 1 (PLK1) activity across a broad spectrum of cancer cell lines. The importance of PIK3CA alterations in squamous cell carcinoma of the head and neck (HNSCC) has raised interest in exploring agents targeting PI3K, the product of PIK3CA. The genetic and molecular basis of rigosertib treatment response was investigated in a panel of 16 HNSCC cell lines, and direct patient tumor xenografts from eight patients with HNSCC [four HPV-serotype16 (HPV16)-positive]. HNSCC cell lines and xenografts were characterized by pathway enrichment gene expression analysis, exon sequencing, gene copy number, Western blotting, and immunohistochemistry (IHC). Rigosertib had potent antiproliferative effects on 11 of 16 HPV(-) HNSCC cell lines. Treatment sensitivity was confirmed in two cell lines using an orthotopic in vivo xenograft model. Growth reduction after rigosertib treatment was observed in three of eight HNSCC direct patient tumor lines. The responsive tumor lines carried a combination of a PI3KCA-activating event (amplification or mutation) and a p53-inactivating event (either HPV16- or mutation-mediated TP53 inactivation). In this study, we evaluated the in vitro and in vivo efficacy of rigosertib in both HPV(+) and HPV(-) HNSCCs, focusing on inhibition of the PI3K pathway. Although consistent inhibition of the PI3K pathway was not evident in HNSCC, we identified a combination of PI3K/TP53 events necessary, but not sufficient, for rigosertib sensitivity.

    The aims of this study were: (i) to analyze the perioperative outcomes of laparoscopic radical nephrectomy for renal cell carcinoma in patients with dialysis-dependent end-stage renal disease and (ii) to reveal perioperative management problems that are unique to these patients. Between June 2004 and June 2011, laparoscopic radical nephrectomy was performed in 39 patients who had renal cell carcinoma and dialysis-dependent end-stage renal disease. The operative outcomes of these patients were compared with the operative outcomes of 104 non-end-stage renal disease patients with sporadic renal cell carcinoma who underwent laparoscopic radical nephrectomy during the same period. Laparoscopic surgery was completed in thirty-eight end-stage renal disease patients. One patient was converted to open surgery because of an intraoperative injury to the inferior vena cava. This patient was excluded from the analysis. The mean operative time was 240 min; blood loss, 157 mL; and postoperative hospital stay, 9.6 days. Postoperative complications were observed in six patients, as follows: retroperitoneal hematoma and abscess in one patient, thrombosis of the arteriovenous fistula in three patients, pneumonia in one patient, and gastrointestinal bleeding in one patient. Eleven patients required blood transfusions. There was no significant difference between the end-stage renal disease patients and the non-end-stage renal disease patients in the mean operative time or the amount of blood loss. In conclusion, laparoscopic radical nephrectomy is feasible for dialysis-dependent end-stage renal disease patients, as well as for non-end-stage renal disease patients; however, end-stage renal disease patients may have a higher probability of experiencing non-life-threatening complications.

    Full Text Available Objective: Therapeutic vaccination with dendritic cells (DC showed promising results in first clinical trials in cases of metastatic renal cell carcinoma (RCC. Human telomerase reverse transcriptase (hTERT could be a potential target because it is detectable in more than 85% of human tumors including RCC. Design: 10 patients with progressive metastatic RCC were enrolled in a clinical phase I/II trial using DC pulsed with hTERT-peptide. Beside toxicity and feasibility aspects, a complex immune monitoring including in vitro data were evaluated. In addition to detection of tumor-specific effector cells we investigated their functionality like IFN-γ secretion and cytotoxic activity against tumor cells. Results: The vaccine was well tolerated. Two patients showed a mixed response (MR and one patient a stable disease (SD. Interestingly, responders showed cytotoxic activity already before start of therapy and there was a significant increase in cytotoxic activity of effector cells from all responders (SD and MR patients after the first vaccination. In contrast non-responders showed no cytotoxic activity before and during treatment. Therefore, cytotoxic activity might be used as a predictive marker in the future. Tetramer staining detected higher amounts of tumor-specific cytotoxic cells in responding patients compared to non-responders. Also, responders possessed increasing amounts of IFN-γ producing immunological effector cells. Conclusion: Telomerase-pulsed DC could enhance a tumor-specific immune response against RCC.

    Histamine inhibits formation and release of phagocyte-derived reactive oxygen species, and thereby protects natural killer and T cells against oxidative damage. Thus, the addition of histamine may potentially improve the efficacy of interleukin-2 (IL-2). Two randomised phase II trials of IL-2...... with or without histamine dihydrochloride (HDC) in patients with metastatic renal cell carcinoma (mRCC) were run in parallel. A total of 41 patients were included in Manchester, UK and 63 in Aarhus, Denmark. The self-administered, outpatient regimen included IL-2 as a fixed dose, 18 MIU s.c. once daily, 5 days...... median survival (18.3 vs 11.4 months, P = 0.07), time to PD (4.5 vs 2.2 months, P = 0.13) and clinical benefit (CR + PR + SD) (58 vs 37%, P = 0.10) in favour of IL-2/HDC, whereas the UK study was negative for all end points. Only three patients had grade 4 toxicity; however, two were fatal. A randomised...

    Full Text Available A Seventy-one-year-old man presented with icterus and malaise. A computed tomography scan showed a tissue mass in the head of the pancreas with compression and dilation of the common bile duct. The patient underwent endoscopic retrograde cholangiopancreatography, a metal stent was placed in the common bile duct and a pancreatoduodenectomy was planned. At operation invasion in the portal vein was observed. On-site histopathology of the tissue revealed only inflammation and no cancer cells. It was therefore decided to perform a gastroenterostomy instead. As autoimmune pancreatitis was suspected, treatment with corticosteroids was started, but did not result in a reduction of tissue mass. After a few months, the patient developed venous thrombosis in the portal and superior mesenteric veins, with colorectal varicose veins and episodes of bleeding. The patient died of excessive weight loss due to mesenteric venous thrombosis. Post-mortem histopathological examination of the soft tissue mass of the head of the pancreas showed signet ring cell carcinoma.

    Celia Prior

    Full Text Available PURPOSE: To identify tissue microRNAs predictive of sunitinib activity in patients with metastatic renal-cell-carcinoma (MRCC and to evaluate in vitro their mechanism of action in sunitinib resistance. METHODS: We screened 673 microRNAs using TaqMan Low-density-Arrays (TLDAs in tumors from MRCC patients with extreme phenotypes of marked efficacy and resistance to sunitinib, selected from an identification cohort (n = 41. The most relevant differentially expressed microRNAs were selected using bioinformatics-based target prediction analysis and quantified by qRT-PCR in tumors from patients presenting similar phenotypes selected from an independent cohort (n = 101. In vitro experiments were conducted to study the role of miR-942 in sunitinib resistance. RESULTS: TLDAs identified 64 microRNAs differentially expressed in the identification cohort. Seven candidates were quantified by qRT-PCR in the independent series. MiR-942 was the most accurate predictor of sunitinib efficacy (p = 0.0074. High expression of miR-942, miR-628-5p, miR-133a, and miR-484 was significantly associated with decreased time to progression and overall survival. These microRNAs were also overexpressed in the sunitinib resistant cell line Caki-2 in comparison with the sensitive cell line. MiR-942 overexpression in Caki-2 up-regulates MMP-9 and VEGF secretion which, in turn, promote HBMEC endothelial migration and sunitinib resistance. CONCLUSIONS: We identified differentially expressed microRNAs in MRCC patients presenting marked sensitivity or resistance to sunitinib. MiR-942 was the best predictor of efficacy. We describe a novel paracrine mechanism through which high miR-942 levels in MRCC cells up-regulates MMP-9 and VEGF secretion to enhance endothelial migration and sunitinib resistance. Our results support further validation of these miRNA in clinical confirmatory studies.

    Full Text Available OBJECTIVES: To investigate the most important factors affecting the prognosis of the patients with squamous cell carcinoma (SCC of the larynx. METHODS: Based on the clinical and follow-up data, 205 patients with SCC of the larynx receiving total laryngectomy, partial laryngectomy, or CO2 laser surgery in GuangDong General Hospital were retrospectively analyzed. A survival analysis was performed by the Kaplan-Meier method and a multivariable analysis of prognostic factors was carried out using the Cox proportional hazard model. RESULTS: Subtypes of carcinoma included 69.8% glottic and 30.2% supraglottic. Most patients were in N0 stage (77.6%, and 22.4% patients were in N1∼N3 stage. Over half of the patients were in T1∼T2 stage (55.1%, 20.0% in T3, and 24.9% in T4. Mean follow-up duration was 49.2 months. The survival rates 1, 2, and 3 years after the surgery were 99.0%, 91.7%, and 81.5%, respectively. The survival rate for those patients with clinical stage IV was significantly lower than for those with clinical stage I and II (p<0.001 and p = 0.013, respectively. The disease-free progression rates 1, 2, and 3 years after the surgery were 83.9%, 74.6%, and 71.2%, respectively. Futhermore, those patients with a Charlson score of 1 to 2 and ≥3 had higher risk of mortality than those with a Charlson score of 0 (hazard ratios of 1.8 and 2.41 p = 0.042 and p = 0.008. Multivariable analysis revealed that clinical stage, surgical margin, and comorbidity were significantly associated with both mortality and disease-free progression. CONCLUSION: The surgical resection margin, clinical stage, and comorbidity were independent factors affecting the laryngeal cancer prognosis. The survival rates were lower for patients with advanced laryngeal cancer, positive surgical margins, or severe comorbidity, suggesting the importance of early diagnosis, early treatment, negative surgical margins, and conditions of comorbidity.

    Squamous cell carcinoma arising from balanitis xerotica obliterans is rarely reported. We describe an 83-year-old man in whom metastatic penile squamous cell carcinoma developed after 18 years of observation for balanitis xerotica obliterans. It is important to recognize the possibility of this uncommon complication of balanitis xerotica obliterans, because survival of patients with squamous cell carcinoma depends on early diagnosis and treatment.

    2015-01-01

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

    Full Text Available Abstract Background Hürthle cell carcinoma is a variant of follicular cell carcinoma of thyroid. It may present as a low-grade tumour or as a more aggressive type. Prognosis depends upon the age of the patient, tumour size, extent of invasion and initial nodal or distant metastasis. Patient and methods The case of Hürthle cell carcinoma is reported in a 79-year-old man who presented with a rapidly increasing lump on the left side of his neck, having had a right hemithyroidectomy for colloid goitre 24-years-ago. Fine needle aspiration cytology confirmed the presence of Hürthle cells, raising the possibility of a Hürthle cell neoplasm. The patient underwent staging and surgery. Histology showed Hürthle cell carcinoma and the patient underwent adjuvant therapy. The literature on Hürthle cell neoplasms is reviewed. Conclusions Fine needle aspiration cytology may recognise Hürthle cell lesion but final diagnosis of carcinoma depends upon histological confirmation of vascular or capsular invasion. Staging and surgery in Hürthle cell carcinoma are similar to follicular carcinoma of thyroid with favourable outcome despite the controversy regarding the histological classification and adjuvant therapy. Elderly patients with Hürthle cell carcinoma need to be made aware of their poorer prognosis and should be offered more radical treatment.

    Full Text Available Duodenal metastasis from renal cell carcinoma is rare, and even rarer is a massive gastrointestinal bleeding from such tumours. Coeliac occlusive disease, although rarely symptomatic, can lead to ischaemic changes with anastomotic dehiscence and leaks when a patient undergoes pancreatoduodenectomy. A 41-year-old man with known metastasis to the adrenal glands and the second part of the duodenum close to the ampulla of Vater from clear cell renal cell carcinoma was admitted to our department due to massive gastrointestinal bleeding from the duodenal metastasis. Endoscopic control of the bleed was not possible, while the bleeding vessel embolization was able to control the haemorrhage only temporarily. An angiography during the embolization demonstrated the presence of stenosis of the coeliac artery and also hypertrophic inferior pancreaticoduodenal arteries supplying the proper hepatic artery via the gastroduodenal artery (GDA. The patient underwent emergency pancreatoduodenectomy with preservation of the gastroduodenal artery. The patient had an uneventful recovery and did not experience further bleeding. Also the blood flow to the liver was compromised as shown by the normal liver function tests (LFTs postoperatively. To the best of our knowledge, this is the first report of a preservation of the GDA during an emergency pancreatoduodenectomy.

    Full Text Available Purpose. Human papillomavirus (HPV as a risk factor for esophageal squamous cell carcinoma (ESCC has previously been studied, but importance of HPV status in ESCC for prognosis is less clear. Methods. A total of 105 specimens with ESCC were tested by in situ hybridization for HPV 16/18 and immunohistochemistry for p16 expression. The 5-year overall survival (OS and progression-free survival were calculated in relation to these markers and the Cox proportional hazards model was used to determine the hazard ratio (HR of variables in univariate and multivariate analysis. Results. HPV was detected in 27.6% (29 of the 105 patients with ESCC, and all positive cases were HPV-16. Twenty-five (86.2% of the 29 HPV-positive tumors were stained positive for p16. HPV infected patients had better 5-year rates of OS (65.9% versus 43.4% among patients with HPV-negative tumors; P = 0.002 by the log-rank test and had a 63% reduction in the risk of death (adjusted HR = 0.37, 95% CI = 0.16 to 0.82, and P = 0.01. Conclusions. HPV infection may be one of many factors contributing to the development of ESCC and tumor HPV status is an independent prognostic factor for survival among patients with ESCC.

    Full Text Available Results of clinical follow-up of the patient with squamous cell skin carcinoma of the nasal dorsum are represented. The patient underwent a course of combined photodynamic therapy (PDT with distant gamma-ray therapy. Distant gamma-ray therapy was performed daily during 12 days (single dose of 3 Gy, total dose of 36 Gy with the first session 24 h after injection of the photosensitization. For PDT the photosensitizer photosens at dose of 0,3 mg/kg was used. The method of prolonged PDT was applied, sessions of laser irradiation were performed daily during 7 days. The PDT sessions were carried out 2 h after session of gamma-ray therapy using distant (150 J/cm2, 40 mW/cm2 and contact (500 J/cm2, 100 mW/cm2 modalities. According to multiple cytological studies after treatment there were no signs of tumor, but inflammation. Four months after treatment according to cytological data continued tumor growth was detected. The patient underwent an additional course of PDT. Currently the patient is under follow-up: no recurrence during 8 months after repeated treatment.

    Full Text Available Abstract Background The autosomal dominant tumor syndrome tuberous sclerosis complex is caused by the mutated TSC1 gene, hamartin, and the TSC2 gene, tuberin. Patients with this complex develop typical cutaneus symptoms such as peau chagrin or angiofibromas of the skin as well as other lesions such as astrocytomas in the brain and lymphangioleiomyomatosis in the lung. Only a few tuberous sclerosis patients have been described who showed a multifocal micronodular pneumocyte hyperplasia of the lung. Another benign tumor which often occurs together with tuberous sclerosis is the angiomyolipoma of the kidney. Furthermore, an increased incidence of renal cell carcinoma in connection with tuberous sclerosis has also been proven. Case presentation We report a 13-year-old white girl with epilepsy and hypopigmented skin lesions. Radiological studies demonstrated the typical cortical tubers leading to the diagnosis of tuberous sclerosis. In the following examinations a large number of angiomyolipomas were found in both kidneys. One lesion showed an increasing size and tumor like aspects in magnetic resonance imaging. The pathological examination of the following tumorectomy demonstrated an unclassified renal cell carcinoma. Four months postoperatively, a follow-up computer tomography revealed multiple bilateral pulmonary nodules. To exclude lung metastases of the renal cell carcinoma, multiple open-lung biopsies were performed. Conclusion Here we report a diagnostically challenging case of a 13-year-old patient with tuberous sclerosis and angiomyolipomas of the kidney who developed an unclassified renal cell carcinoma as well as multifocal micronodular pneumocyte hyperplasia.

    Full Text Available Primary pancreatic small cell carcinoma (SCC is rare, with just over 30 cases reported in the literature. Only 7 of these patients underwent surgical resection with a median survival of 6 months. Prognosis of SCC is therefore considered to be poor, and the role of adjuvant therapy is uncertain. Here we report two institutions’ experience with resectable pancreatic SCC. Six patients with pancreatic SCC treated at the Johns Hopkins Hospital (4 patients and the Mayo Clinic (2 patients were identified from prospectively collected pancreatic cancer databases and re-reviewed by pathology. All six patients underwent a pancreaticoduodenectomy. Clinicopathologic data were analyzed, and the literature on pancreatic SCC was reviewed. Median age at diagnosis was 50 years (range 27-60. All six tumors arose in the head of the pancreas. Median tumor size was 3 cm, and all cases had positive lymph nodes except for one patient who only had five nodes sampled. There were no perioperative deaths and three patients had at least one postoperative complication. All six patients received adjuvant therapy, five of whom were given combined modality treatment with radiation, cisplatin, and etoposide. Median survival was 20 months with a range of 9-173 months. The patient who lived for 9 months received chemotherapy only, while the patient who lived for 173 months was given chemoradiation with cisplatin and etoposide and represents the longest reported survival time from pancreatic SCC to date. Pancreatic SCC is an extremely rare form of cancer with a poor prognosis. Patients in this surgical series showed favorable survival rates when compared to prior reports of both resected and unresectable SCC. Cisplatin and etoposide appears to be the preferred chemotherapy regimen, although its efficacy remains uncertain, as does the role of combined modality treatment with radiation.

This study was designed to explore the prognostic significance of lymphocyte-to-monocyte ratio (LMR and serum C-reactive protein (CRP in nonmetastatic clear cell renal cell carcinoma (ccRCC patients after treatment.Methods: The retrospective study consisted of 985 patients with ccRCC who had undergone nephrectomy from 2005 to 2010 at multiple centers. The patients were divided into four groups using a quartile of LMR or CRP, and their associations with clinical characteristics and outcome were systematically estimated.Results: Both low LMR and high CRP significantly diminished overall survival (OS and metastasis-free survival (MFS in patients with ccRCC. Further investigation indicated that LMR and CRP were independent prognostic factors of both OS and MFS. Integration of LMR and CRP into a predictive model, including significant variables in multivariate analysis, established a nomogram to predict accurately the 3- and 5-year survival for nonmetastatic patients with ccRCC.Conclusion: LMR and CRP represent independent prognostic factors of OS and MFS for patients with ccRCC. Incorporation of LMR and CRP into the traditional TNM staging system may improve their predictive performance.

    Materials and Methods: Peripheral blood was collected by venepuncture and comet assay was performed using SCGE. Mean tail length was compared between diagnostic groups and between different oral habit groups using t-tests and analysis of variance (ANOVA. Pearson′s product moment correlation was used to examine the linear association between the extent of DNA damage and oral habit pack-years. Scheffe′s pair-wise test was employed to adjust for multiple comparisons. Results: None of the controls were associated with any oral habits. Mean (±SD tail lengths (in mm for cancer (24.95 ± 5.09 and leukoplakia (12.96 ± 2.68 were significantly greater than in controls (8.54 ± 2.55, P<0.05. After adjustment, well-, moderately, and poorly differentiated carcinomas had significantly greater tail length than controls. Whereas the extent of DNA damage in cancer cases was significantly greater in leukoplakia than in compared to OSMF (11.03 ± 5.92, the DNA damage in latter was not different from controls. DNA damage for people with any oral habit (19.78 ± 7.77 was significantly greater than those with no habits (8.54 ± 2.55; P<0.0001. Conclusions: DNA damage measured by SCGE is greater in leukoplakia and squamous cell carcinoma, but not in OSMF. Deleterious oral habits are also associated with greater DNA damage.

    Basaloid squamous cell carcinoma of the esophagus is a rare variant of squamous cell carcinoma. We reviewed 878 cases of esophageal squamous cell carcinoma and detected 22 cases (3%) of basaloid squamous cell carcinoma. These tumors and stage-matched paired conventional squamous cell carcinomas were investigated for clinicopathologic features and immunoreactivity of cytokeratin subtypes, p53, B-cell lymphoma 2 (bcl-2), β-catenin, and epidermal growth factor receptor. Molecular aberrations in p53, CTNNB1 (the gene encoding β-catenin), and epidermal growth factor receptor (EGFR) were also determined. Patients with basaloid squamous cell carcinomas demonstrated a 5-year survival rate of 42%, significantly worse than those with well-differentiated squamous cell carcinoma (Pcarcinomas, the basaloid squamous cell carcinomas were less immunoreactive for cytokeratin 14, cytokeratin 903, and membranous β-catenin (Pcarcinomas, low-level expression of cytokeratin 14/cytokeratin 903 and mutations of p53 and EGFR had a significant influence on worse survival (Pcarcinoma, a neoplasm with particularly aggressive biologic behavior, should be differentiated from conventional squamous cell carcinomas. In this context, immunohistochemical assessment of several markers might provide a useful adjunct diagnostic tool. Aberrations of p53 and epidermal growth factor receptor genes are possibly involved in progression of esophageal basaloid squamous cell carcinoma.

    Full Text Available Large-cell neuroendocrine carcinomas of the lung are extremely rare. There are difficulties related to the diagnosis and treatment and there are no consensus because of the small number of studies. 65-year-old male patient presented with hemoptysis. Chest X-ray and thoracic computorized tomography scan showed a mass lesion and it could not be diagnosed by bronchoscopic biopsy and lavage. Lobectomy was performed due to the high value of standardized uptake value in positron emission tomography. Large cell neuroendocrine carcinoma was diagnosed with pathological evaluation and immunohistochemical study and after 20-month follow-up there was no recurrence. The diagnosis, treatment, and prognosis of large cell neuroendocrine carcinoma in the light of the literature is presented.

    Oral squamous cell carcinoma (OSCC) is considered to be one of the most fatal diseases worldwide, owing to its late diagnosis and lack of availability of established reliable biomarkers. The aim of this study was to highlight the significance of immunosuppressive cytokines as potential biomarkers in OSCC. Whole unstimulated saliva was collected from each individual (30 OSCC patients and 33 age- and gender-matched healthy controls). Immunosuppressive cytokines, including IL-4, IL-10, IL-13, and IL-1RA, were evaluated in each sample using Luminex multianalyte profiling (xMAP) technology on BioPlex instrument. Our results showed that all the studied salivary cytokines were raised in OSCC patients as compared to controls, where IL-10 and IL-13 salivary levels showed statistically significant difference (p = .004 and p = .010, respectively). Mean levels of salivary cytokines in three histologically defined OSCC categories, compared employing one-way ANOVA, showed that salivary levels of IL-1RA were highest in patients having poorly differentiated OSCC tumors as compared to those having moderately and well-differentiated tumors (p = .000 and p = .002, respectively). Among OSCC individuals, duration of smokeless tobacco correlated positively with IL-1RA (p = .036). We conclude that salivary levels of immunosuppressive cytokines, IL-4, IL-10, IL-13, and IL-1RA, could prove to be potential biomarkers of OSCC and can be further investigated as markers of early detection and disease progression.

    In collaboration with the Radiotherapeutic Hospital, 87 patients with squamous cell carcinomas of the oral cavity and the oropharynx were treated by combined pre-irradiation and surgical intervention at the University ORL Hospital of Cologne. The study was supposed to improve the five-year survival of patients suffering from advanced carcinomas of the head and neck area. The male and female patient's ratio was 4,5 to 1. Half of the patients had squamous cell carcinomas of the oropharynx, 21 patients had tumors of the floor of the mouth, and another 21 had tumors of the anterior two thirds of the tongue. The tumor and lymph node status was classified according to the UICC regulations (1979). In the pre-irradiation, 40 to 50 Gy were applied to the primary tumor and the regional lymph nodes. Surgery was executed generally four weeks after pre-irradiation. The tumor remission following to pre-irradiation was very good. 27% of the patients showed little or moderate post-operative disturbances in wound healing. An osteoradionecrosis was found in 4,6%. Almost 25% of the patients developed local recurrences. The cumulated five-year survival of all patients is 32%. In dependence on TNM stages, the three-year survival rates are as follows: stage I and II 80%, stage III 44%, and stage IV 40%.

    Hürthle cell carcinoma is a rare variant of differentiated thyroid cancer that occasionally forms distant metastases. However, even in the presence of metastases, patients with Hürthle cell carcinoma have a relatively good prognosis. There are few reports of Hürthle cell carcinoma metastases to the vertebral column, and none describing aggressive resection of spinal metastases. Here, we report a 68-year-old woman with a solitary metastasis of Hürthle cell carcinoma to the T1 vertebral body causing severe kyphotic deformity, myelopathy, and pain. The patient was treated with aggressive excisional decompression of the spinal cord and T1 vertebral body resection from an entirely posterior approach. Reconstruction and stabilization of the anterior spine was accomplished with a transforaminal lumbar interbody fusion allograft spacer and posterior instrumentation. We discuss aspects of the diagnosis, management, patient selection, and surgical treatment of metastatic Hürthle cell carcinoma in reference to the literature.

We investigated the true prognostic effect of BMI and its potential modification by smoking status in ESCC. Methods: We retrospectively analyzed 459 patients who underwent curative treatment at a single institution between January 2007 and December 2010. BMI was calculated using the measured height and weight before surgery. Chi-square test was used to evaluate the relationships between smoking status and other clinicopathological variables. The Cox proportional hazard models were used for univariate and multivariate analyses of variables related to overall survival. Results: BMI <18.5 kg/m2 was a significantly independent predictor of poor survival in the overall population and never smokers after adjusting for covariates, but not in ever smokers. Among never smokers, underweight patients (BMI <18.5 kg/m2 had a 2.218 times greater risk of mortality than non-underweight (BMI =18.5 kg/m2 patients (P=0.015. Among ever smokers, BMI <18 kg/m2 increased the risk of mortality to 1.656 (P=0.019, compared to those having BMI =18 kg/m2. Conclusion: Our study is likely the first to show that the prognostic effect of BMI was substantial in ESCC, even after stratifying by smoking status. Furthermore, the risk of death due to low BMI would be significantly increased in never smokers. We believe that

However, coexpression of PN and EGFR in esophageal squamous cell carcinoma (ESCC still remains unknown. We aimed to clarify their relationship with clinicopathological factors and prognostic significance of their coexpression in ESCC. Patients and methods: In this single-center retrospective study, immunohistochemistry was performed to evaluate the expression of PN and EGFR in ESCC and paracarcinomatous tissues of 83 patients. The quantitative expression levels of PN and EGFR were examined in two ESCC and tumor-adjacent tissues. The levels of PN and EGFR expression were correlated with clinicopathological parameters by the χ2 or Kruskal–Wallis method. Spearman’s rank correlation test was performed to determine the relationship between PN and EGFR expression levels. Kaplan–Meier and Cox regression analyses were used to detect the prognostic factors of disease-free survival (DFS and overall survival (OS. Results: The high expression of PN protein in ESCC tissues was significantly associated with tumor length (P=0.044, differentiation grade (P=0.003, venous invasion (P=0.010, invasion depth (P=0.007, lymphatic metastasis (P=0.000, and tumor stage (P=0.000. The high expression of EGFR protein in ESCC tissues was only significantly related to lymphatic metastasis (P=0.000, invasion depth (P=0.022, and tumor stage (P=0.000. Kaplan–Meier analysis showed that high expression of PN was closely correlated to reduced OS (P=0.000 and DFS (P=0.000, which was consistent with EGFR expression. Cox regression analysis identified PN and EGFR as independent poor prognostic factors of OS and DFS

    We analysed the biologic properties of a small cell lung carcinoma cell line (designated KK0206) established from a patient with SCLC who had cancer-associated retinopathy (CAR). Morphological and immunohistochemical studies showed that KK0206 cells have features of the classic type of SCLC. KK0206 cells grew in suspension, forming relatively small clumps of cells with a doubling time of 72 h. On light microscopy, the cells were relatively small with little cytoplasm. On immunohistochemistry using anti-bovine recoverin rabbit antibody, the cells were intensely positive for recoverin. In addition, they were positive for NSE, Ki-67, and TP53. They also expressed human recoverin, a photoreceptor protein, whose presence was confirmed by RT-PCR analysis with cDNA sequencing and Western blot analysis. The point mutation of their TP53 gene (exon 156) was detected as well. The present study demonstrates that human recoverin is expressed in SCLC cells cultured from an anti-recoverin antibody-negative patient with CAR. KK0206 might be important for further research on SCLC related retinopathy.

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.

    Background Primary small cell carcinoma of the esophagus is rare. Although surgery is successful in eradicating local tumor, the five-year survival rate of patients with primary small cell carcinoma of the esophagus after resection is lower than that of patients with primary squamous cell carcinoma of the esophagus. The purpose of this study was to analyze the clinical manifestations, pathological features and treatment of primary small cell carcinoma of the esophagus.Methods A total of 73 patients with primary small cell carcinoma of the esophagus who had been treated by surgery from 1984 to 2003 were analyzed retrospectively.Results In this series, the overall resection rate was 94.5% (69/73), the radical resection rate 89.0% (65/73) and the operative mortality 1.4% (1/73). The 1-, 3- and 5-year survival rates of patients were 50.7%, 13.7% and 8.2%,respectively.Conclusions Primary small cell carcinoma of the esophagus is rare with a poor prognosis. Surgical resection is the leading method for patients with stage Ⅰ or Ⅱ primary small cell carcinoma of the esophagus. Postoperative chemotherapy is beneficial to these patients. The patients of stage Ⅲ or Ⅳ should be given chemotherapy and radiation therapy.

    The presence of pleomorphic tumor giant cells in thyroid carcinomas of follicular cell origin is always worrisome for the pathologist as they first of all refer to anaplastic carcinoma, one of the most aggressive human malignancies. However, non-anaplastic pleomorphic giant cells are well described in other thyroid diseases, most often benign. In this paper, we describe four cases of papillary thyroid carcinoma displaying pleomorphic tumor giant cells with features that differ from those of anaplastic carcinoma. Pleomorphic giant cells were admixed with the underlying thyroid carcinoma and constituted from 5% to 25% of the tumor. Cytologically, they had an abundant eosinophilic cytoplasm with large and irregular nuclei. Compared to pleomorphic giant cells of anaplastic carcinoma, they reproduced the growth pattern of the underlying carcinoma, had a low mitotic index without necrosis or inflammation, and were reactive with thyroglobulin and thyroid-specific transcription factor-1 and strongly and diffusely positive for cytokeratin AE1/AE3. After 16-84 months of follow-up, patients are relapse-free and still alive. These cases show that pleomorphic tumor giant cells arising in papillary thyroid carcinomas do not always represent dedifferentiation and progression to anaplastic carcinoma. Distinction among these processes is critical as their treatment and prognosis are very different.

    Full Text Available Lysosomal-associated membrane protein 3 (LAMP3, identified as a molecular marker of mature dendritic cells, is one of the LAMP family members. Its expression was induced by hypoxia, and was associated with hypoxia mediated metastasis in breast and cervical cancers. However, epithelial expression of LAMP3 and its prognostic value in esophageal squamous cell carcinoma (ESCC is still unknown. In the current study, mRNA expression of LAMP3 in 157 ESCC tissues and 50 adjacent normal tissues was detected by quantitative real-time PCR (qRT-PCR. LAMP3 protein expression in 46 paired cancerous and normal tissues was detected by immunohistochemistry (IHC. Then, DNA copy number was examined to observe its potential correlation with mRNA expression. The results showed that both mRNA and protein expression level of LAMP3 was significantly higher in cancerous tissues compared with normal controls (p < 0.001. LAMP3 DNA copy number was amplified in 70% of ESCC tissues and positive correlated with mRNA expression (p = 0.037. Furthermore, patients with higher LAMP3 expression had worse overall survival (HR = 1.90, 95% CI = 1.17–3.09, p = 0.010 and disease-free survival (HR = 1.80, 95% CI = 1.18–2.74, p = 0.006. In conclusion, our results suggest that epithelial LAMP3 expression is an independent prognostic biomarker for ESCC.

    Background:Recently, studies have shown that plasma D‑dimer and serum albumin are prognostic markers for esophageal cancer. The purpose of this study was to evaluate a novel prognostic scoring system—DA score (combi‑nation of preoperative plasma D‑dimer and serum albumin levels)—and analyze the association between survival of patients with esophageal squamous cell carcinoma (ESCC) and their Glasgow prognostic score. Methods:In this retrospective study, preoperative biochemical markers and clinicopathologic factors in 260 ESCC patients treated with transthoracic esophagectomy were reviewed. According to receiver operating characteristic analysis, the cutoff values of D‑dimer and albumin were deifned as 0.5μg/mL and 43.8g/L, respectively. Patients with high D‑dimer levels (≥0.5μg/mL) and low albumin levels (<43.8g/L) were assigned a score of 2, those with only one of the two abnormalities were assigned a score of 1, and those with neither of the two abnormalities were assigned a score of 0. Results:ESCC patients with a DA score of 0, 1, and 2 numbered 55, 116, and 89, respectively. Survival analysis showed that patients with a DA score of 2 had lower overall survival (OS) rates than those with DA scores of 1 and 0 (37.1% vs. 52.6% and 76.4%,P<0.001); similar ifndings were observed for disease‑free survival (DFS) rates (32.6% vs. 44.8% and 67.3%,P<0.001). In addition, the predictive value of the DA score was also signiifcant in patients with stages I–IIA and stages IIB–IV ESCC. Multivariate Cox regression analyses indicated that hazard ratios (HRs) for predicting OS of patients with DA scores 1 and 2 were 2.25 (P=0.010) and 3.14 (P<0.001), respectively, compared with those with a DA score of 0, and HRs for predicting DFS of patients with DA scores of 1 and 2 were 1.86 (P=0.023) and 2.68 (P<0.001), respectively, compared with those with a DA scores of 0. Conclusions:Our study suggests that preoperative DA scores are notably associated with

    Most Merkel cell carcinomas display pure neuroendocrine differentiation (pure Merkel cell carcinoma), whereas a minority show combined neuroendocrine and nonneuroendocrine elements (combined Merkel cell carcinoma). Recent identification of Merkel cell polyomavirus DNA and Merkel cell polyomavirus large T antigen expression in a proportion of Merkel cell carcinomas has suggested viral-induced oncogenesis. To date, Merkel cell polyomavirus immunohistochemistry has shown an absence of viral large T antigen expression in combined Merkel cell carcinoma as well as select non-Merkel cell carcinoma cutaneous lesions and visceral neuroendocrine tumors. In our series, we aimed to further characterize the frequency and pattern of Merkel cell polyomavirus large T antigen expression by CM2B4 immunohistochemistry in primary and metastatic Merkel cell carcinoma (pure Merkel cell carcinoma and combined Merkel cell carcinoma) and various non-Merkel cell carcinoma lesions from patients with Merkel cell carcinoma, patients without Merkel cell carcinoma, and individuals with altered immune function. Merkel cell polyomavirus large T antigen was detected in 17 (63%) of 27 pure Merkel cell carcinomas and absent in all 15 (0%) combined Merkel cell carcinomas. Furthermore, complete concordance (100%) of Merkel cell polyomavirus large T antigen expression was observed in 10 cases of primary Merkel cell carcinoma and subsequent tumor metastases. We also evaluated 70 non-Merkel cell carcinoma lesions including 15 cases each of pulmonary and gastrointestinal neuroendocrine tumors. All 70 non-Merkel cell carcinoma lesions were negative for Merkel cell polyomavirus by CM2B4 immunohistochemistry, irrespective of any known Merkel cell carcinoma diagnosis and immune status. In summary, our identification of Merkel cell polyomavirus large T antigen expression in a subset of Merkel cell carcinoma and lack of findings in combined Merkel cell carcinomas and non-Merkel cell carcinoma lesions concur with

Patients and methods: In this retrospective analysis, mRCC patients in two institutions in Latin America received sunitinib at a starting dose of either 50 mg/day for 4 weeks followed by 2 weeks off treatment (Schedule 4/2 in repeated 6-week cycles or sunitinib 37.5 mg on a continuous daily dosing schedule. Clinical characteristics, tolerability, and PFS data were collected. Results: Twenty-nine patients with long-term clinical benefit from sunitinib were identified between September 2005 and August 2009. Median PFS was 23 months (range: 15–54 months. Two of the 29 patients with prolonged PFS achieved a complete response and additional eleven had a partial response. Most patients were aged <60 years, had good performance status, favorable or intermediate Memorial Sloan Kettering Cancer Center prognostic risk, and disease limited to one or two sites. Dose reduction was necessary in all patients who started sunitinib at 50 mg/day administered on Schedule 4/2. Adverse events leading to dose reduction included grade 3 hand–foot syndrome, mucositis, fatigue, and hypertension. At the time of data cutoff, four patients were still receiving sunitinib treatment. Conclusion: Extended PFS can be achieved in Latin American patients with mRCC treated with sunitinib. Although the small sample size and retrospective nature of this evaluation preclude the identification of pretreatment predictive factors contributing to this benefit, the current analysis warrants

    Full Text Available Lung cancer (LC and colorectal cancer (CRC are the first and second deadliest types of cancer worldwide. EGFR-based therapy has been used in the treatment of these cancers with variable success. Presence of mutations in the KRAS driver oncogene, possibly induced by environmental factors such as carcinogens in diet and cigarette smoke, may confer worse prognosis and resistance to treatment for reasons not fully understood. Data on possible associations between KRAS mutational status and clinical and metabolic parameters, which may help in clinical management, as well as in identifying risk factors for developing these cancers, are limited in the current literature. We sequenced the KRAS gene and investigated the associations of variations in 108 patients with non-small cell lung carcinoma (NSCLC, the most common form of LC, and in 116 patients with CRC. All of the mutations originated from the guanosine nucleotide and over half of all transversions in NSCLC and CRC were c.34 G>T and c.35 G>T, respectively. c.35 G>A was the most frequent type of transition in both cancers. Excluding smoking, the clinical and metabolic parameters in patients carrying mutant and wild type KRAS were similar except that the CRC patients with transversion mutations were 8.6 years younger than those carrying the transitions (P < 0.01. Dyslipidemia, hypertension, family cancer history, and age of diagnosis older than 60 years were more frequent in NSCLC than CRC (P ≤ 0.04. These results suggest that most of the clinical and metabolic parameters investigated in this study are probably not associated with the more aggressive phenotype and differences in response to EGFR-based treatment previously reported in patients with KRAS mutations. However, the increased rates of abnormal metabolic parameters in patients with NSCLC in comparison to CRC indicate that these parameters may be more important in the management of NSCLC. CRC patients carrying transition mutations are

    Full Text Available Pulmonary diseases [asthma, chronic obstructive pulmonary disease (COPD, and tuberculosis (TB] are associated with lung cancer mortality. However, the relationship between coexisting pulmonary diseases and survival in patients with lung squamous cell carcinoma (SqCC has not been well defined.Patients newly diagnosed with SqCC between 2003 and 2008 were identified by linking the National Health Insurance Research Database and Taiwan Cancer Registry Database. Cases with SqCC were followed up until death, loss to follow-up, or study end in 2010. Information on health status, date of death and the main causes of death was ascertained from the National Death Registry Database. Cox proportional hazard regression was used to calculate the hazard ratio (HR of coexisting asthma, COPD and/or TB.During the study period, a total of 5406 cases with SqCC were enrolled. For all cause-mortality, HRs were 1.08 [95% confidence interval (CI, 0.99-1.18], 1.04 (95% CI, 0.97-1.12, and 1.14 (95% CI, 1.00-1.31 for individuals with asthma, COPD, and TB, respectively. Specifically, among men with coexisting pulmonary diseases, the HRs were 1.56 (95% CI, 1.23-1.97 and 1.11 (95% CI, 1.00-1.24 for individuals with asthma+COPD+TB and asthma+COPD, respectively. Among male patients with stage III SqCC, HRs were 3.41 (95%CI, 1.27-9.17 and 1.65 (95%CI, 1.10-2.47 for individuals with asthma+TB and asthma+COPD+TB, respectively. Among male patients with stage IV SqCC, HRs were 1.40 (95%CI, 1.00-1.97 and 1.25 (95%CI, 1.03-1.52 for individuals with asthma+ COPD+TB and asthma. Among female patients with stage I and II, HR was 0.19 (95%CI, 005-0.77 for individuals with asthma.Coexisting pulmonary diseases increased the risk of mortality from SqCC in male patients. For female patients with early stage SqCC, pre-existing asthma decreased mortality. These patients deserve greater attention while undergoing cancer treatment.

    Full Text Available Giant basal cell carcinomas (GBCCs are large basal cell carcinomas (BCCs; <5 cm with a greater propensity to invade and metastasize than standard BCCs. The presence of 2 GBCCs in a single individual is rare. We present the case of a 71-year-old Caucasian male with bilateral GBCCs on the dorsal forearms, measuring 130 cm2 and 24 cm2, respectively, that developed over a 21-year period. Over this period, the patient treated the tumors with herbal remedies. Histologic evaluation showed a conventional nodular BCC for both tumors. Computed tomography and magnetic resonance imaging revealed a T4N0M0 stage for the larger lesion. Surgical excision and grafting and reconstruction were offered, but he declined. This case highlights a shared belief in holistic treatments and rejection of Western medical interventions that are common among many patients with GBCC. Studies reporting nonsurgical treatments for GBCCs, including radiotherapy, vismodegib, topical imiquimod, and acitretin are reviewed.

    Squamous cell carcinoma (SCC) of the lung represents 30% of non-small cell lung cancers (NSCLC). Docetaxel and the EGFR tyrosine kinase inhibitor (TKI), erlotinib, are the only two drugs approved for second-line treatment of advanced SCC. The sensitivity of SCC to TKIs can be explained by EGFR overexpression. Erlotinib demonstrated a significant benefit in terms of overall survival (OS) in successive lines in NSCLC, including squamous histology. The magnitude of this benefit is similar to that of chemotherapy. Afatinib is an irreversible inhibitor of the entire ErbB family (EGFR, HER2-4) that has recently been approved for its current indication, advanced EGFR mutation-positive NSCLC and has well-defined and manageable toxicity, mainly gastrointestinal and cutaneous. The LUX-Lung 8 study was a phase III randomized trial in patients with NSCLC with squamous histology that compared erlotinib versus afatinib as second-line treatment. A total of 795 patients were included and a significant benefit was observed for afatinib in progression-free survival (2.7 vs 1.9 months (HR 0.79 [95%CI 0.68-0.91]; p=0.0012) and in OS (7.9 vs 6.8 months (HR 0.81 [95%CI 0.69-0.95]; p=0.0077), as well as a significant improvement in OS at 12 and 18 months. More diarrhoea and stomatitis was observed with afatinib and more rash with erlotinib, but the overall proportion of toxicity was similar in each group. Afatinib offered better results in quality of life. In summary, afatinib is a second-line treatment option in squamous NSCLC based on its survival advantage over erlotinib.

  6. Dll4 blockade potentiates the anti-tumor effects of VEGF inhibition in renal cell carcinoma patient-derived xenografts.

    Directory of Open Access Journals (Sweden)

    Kiersten Marie Miles

    Full Text Available BACKGROUND: The Notch ligand Delta-like 4 (Dll4 is highly expressed in vascular endothelium and has been shown to play a pivotal role in regulating tumor angiogenesis. Blockade of the Dll4-Notch pathway in preclinical cancer models has been associated with non-productive angiogenesis and reduced tumor growth. Given the cross-talk between the vascular endothelial growth factor (VEGF and Delta-Notch pathways in tumor angiogenesis, we examined the activity of a function-blocking Dll4 antibody, REGN1035, alone and in combination with anti-VEGF therapy in renal cell carcinoma (RCC. METHODS AND RESULTS: Severe combined immunodeficiency (SCID mice bearing patient-derived clear cell RCC xenografts were treated with REGN1035 and in combination with the multi-targeted tyrosine kinase inhibitor sunitinib or the VEGF blocker ziv-aflibercept. Immunohistochemical and immunofluorescent analyses were carried out, as well as magnetic resonance imaging (MRI examinations pre and 24 hours and 2 weeks post treatment. Single agent treatment with REGN1035 resulted in significant tumor growth inhibition (36-62% that was equivalent to or exceeded the single agent anti-tumor activity of the VEGF pathway inhibitors sunitinib (38-54% and ziv-aflibercept (46%. Importantly, combination treatments with REGN1035 plus VEGF inhibitors resulted in enhanced anti-tumor effects (72-80% growth inhibition, including some tumor regression. Magnetic resonance imaging showed a marked decrease in tumor perfusion in all treatment groups. Interestingly, anti-tumor efficacy of the combination of REGN1035 and ziv-aflibercept was also observed in a sunitinib resistant ccRCC model. CONCLUSIONS: Overall, these findings demonstrate the potent anti-tumor activity of Dll4 blockade in RCC patient-derived tumors and a combination benefit for the simultaneous targeting of the Dll4 and VEGF signaling pathways, highlighting the therapeutic potential of this treatment modality in RCC.

    Full Text Available Abstract Background Ten cancer patients (Six renal cell carcinoma and four breast cancer patients were treated in a phase I/II study with a vaccine composed of autologous dendritic cells (DCs and IL-2 to evaluate the DC vaccine-related toxicity and antigen-specific immune alteration. Methods Cancer patients were treated twice with autologous CD34+ hematopoietic stem cell-derived, GM-CSF/IFN-γ-differentiated DCs pulsed with autologous tumor lysate and KLH, by 4-week interval. Following each subcutaneous injection of therapeutic DCs, low-dose (200 MIU IL-2 was introduced for 14 consecutive days as an immune adjuvant. To determine the DC vaccine-induced immunological alterations, the KLH-specific lymphocyte proliferation, number of IFN-γ secreting T cells (ELISPOT assay, NK activity and the cytokine modulation were measured. Results Cultured-DCs expressing HLA-DR, CD11c, CD83, and B7.1/B7.2 produced IL-12p70. After vaccination, the patients tolerated it. Clinical response was observed in one RCC patient as stable disease. However DC-vaccine related antigen-specific immune responses including peripheral blood lymphocyte proliferation and the number of IFN-r secreting cells were induced in six patients without clear correlation with clinical responses. Also NK activity was induced significantly in six patients after vaccination. DC vaccine-related decrease of TGF-β level or increase of IL-12p70 level and decline of CD4+CD25+ T cells were observed in three patients. However only in the RCC patient whose disease stabilized, combination of stimulatory as well as inhibitory immune alterations including induction of IFN-γ secreting T cell with reduction of CD4+ CD25+ T cell were correlated with clinical responses. Conclusion Data indicated that DC vaccine combined with IL-2 is well tolerated without major side effects. DC vaccine induced the specific immunity against introduced antigen.

    Full Text Available Abstract We report two cases of gastrointestinal perforation (GIP after radiotherapy in patients receiving tyrosine kinase inhibitor (TKI for advanced renal cell carcinoma (RCC. Case 1 was a 61-year-old woman with lung metastases after a radical nephrectomy for a right RCC (cT3aN0M0 treated with interferon-alpha (OIF, 5 MIU, three times per week. She developed lytic metastases of the left femur and the left acetabulum. She was treated with palliative radiotherapy to the metastatic portion (3 Gy × 10 fractions, and 400 mg sorafenib twice per day plus continuing interferon alpha. She experienced sudden left lower abdominal pain after four weeks of treatment, and was diagnosed with a perforation of the sigmoid colon with fecal peritonitis. Case 2 was a 48-year-old man with lung, lymph node, and bone metastases after a radical nephrectomy for a right RCC (cT2N0M0, and was treated with 400 mg sorafenib twice per day. He developed lytic bone metastases of the lumbar vertebrae, which was treated with palliative radiotherapy to L2-4 (3 Gy × 10 fractions. He experienced sudden abdominal pain after two months of radiation treatment, and was diagnosed with a perforation of the sigmoid colon with fecal peritonitis. These cases underwent radiotherapy, and therefore this may be related to the radiosensitivity of TKI.

    Full Text Available We report a patient with metastatic clear-cell renal cell carcinoma (mRCC who presented with primary tumor in situ in the left kidney and metastases to bone, liver, lungs, and brain. After over 5 years of sunitinib therapy and subsequent cytoreductive left nephrectomy, the patient achieved radiographic complete response (CR and had pathologic CR in the nephrectomy specimen. Durable clinical and pathological CRs are possible with targeted agents, even with primary tumor in situ and widely disseminated metastases. Ongoing research will define the optimal duration of systemic therapy in exceptional responders and identify the molecular determinants of response and resistance.

O tratamento consiste de radio e/ou quimioterapia, eventualmente seguidos pela ressecção do tumor. 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.

  16. Analyses of potential predictive markers and survival data for a response to sunitinib in patients with metastatic renal cell carcinoma.

    Directory of Open Access Journals (Sweden)

    Juana Dornbusch

    Full Text Available BACKGROUND: Patients with metastatic clear cell renal cell carcinoma (ccRCC are frequently treated with tyrosine kinase inhibitors (TKI such as sunitinib. It inhibits angiogenic pathways by mainly targeting the receptors of VEGF and PDGF. In ccRCC, angiogenesis is characterized by the inactivation of the von Hippel-Lindau gene (VHL which in turn leads to the induction of HIF1α target genes such as CA9 and VEGF. Furthermore, the angiogenic phenotype of ccRCC is also reflected by endothelial markers (CD31, CD34 or other tumor-promoting factors like Ki67 or survivin. METHODS: Tissue microarrays from primary tumor specimens of 42 patients with metastatic ccRCC under sunitinib therapy were immunohistochemically stained for selected markers related to angiogenesis. The prognostic and predictive potential of theses markers was assessed on the basis of the objective response rate which was evaluated according to the RECIST criteria after 3, 6, 9 months and after last report (12-54 months of sunitinib treatment. Additionally, VHL copy number and mutation analyses were performed on DNA from cryo-preserved tumor tissues of 20 ccRCC patients. RESULTS: Immunostaining of HIF-1α, CA9, Ki67, CD31, pVEGFR1, VEGFR1 and -2, pPDGFRα and -β was significantly associated with the sunitinib response after 6 and 9 months as well as last report under therapy. Furthermore, HIF-1α, CA9, CD34, VEGFR1 and -3 and PDGRFα showed significant associations with progression-free survival (PFS and overall survival (OS. In multivariate Cox proportional hazards regression analyses high CA9 membrane staining and a response after 9 months were independent prognostic factors for longer OS. Frequently observed copy number loss and mutation of VHL gene lead to altered expression of VHL, HIF-1α, CA9, and VEGF. CONCLUSIONS: Immunoexpression of HIF-1α, CA9, Ki67, CD31, pVEGFR1, VEGFR1 and -2, pPDGFRα and -β in the primary tumors of metastatic ccRCC patients might support the

    {sup 18}F-fluoro-2-deoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) is widely used to diagnose and stage non-small cell lung cancer (NSCLC). The aim of this retrospective study was to evaluate the predictive ability of different FDG standardized uptake values (SUVs) in 74 patients with newly diagnosed NSCLC. {sup 18}F-FDG PET/CT scans were performed and different SUV parameters (SUV{sub max}, SUV{sub avg}, SUV{sub T/L}, and SUV{sub T/A}) obtained, and their relationship with clinical characteristics were investigated. Meanwhile, correlation and multiple stepwise regression analyses were performed to determine the primary predictor of SUVs for NSCLC. Age, gender, and tumor size significantly affected SUV parameters. The mean SUVs of squamous cell carcinoma were higher than those of adenocarcinoma. Poorly differentiated tumors exhibited higher SUVs than well-differentiated ones. Further analyses based on the pathologic type revealed that the SUV{sub max}, SUV{sub avg}, and SUV{sub T/L} of poorly differentiated adenocarcinoma tumors were higher than those of moderately or well-differentiated tumors. Among these four SUV parameters, SUV{sub T/L} was the primary predictor for tumor differentiation. However, in adenocarcinoma, SUV{sub max} was the determining factor for tumor differentiation. Our results showed that these four SUV parameters had predictive significance related to NSCLC tumor differentiation; SUV{sub T/L} appeared to be most useful overall, but SUV{sub max} was the best index for adenocarcinoma tumor differentiation.

    Purpose: Small cell carcinomas of the bladder (SCCB) account for fewer than 1% of all urinary bladder tumors. There is no consensus regarding the optimal treatment for SCCB. Methods and Materials: Fifteen academic Rare Cancer Network medical centers contributed SCCB cases. The eligibility criteria were as follows: pure or mixed SCC; local, locoregional, and metastatic stages; and age ≥18 years. The overall survival (OS) and disease-free survival (DFS) were calculated from the date of diagnosis according to the Kaplan-Meier method. The log-rank and Wilcoxon tests were used to analyze survival as functions of clinical and therapeutic factors. Results: The study included 107 patients (mean [±standard deviation, SD] age, 69.6 [±10.6] years; mean follow-up time, 4.4 years) with primary bladder SCC, with 66% of these patients having pure SCC. Seventy-two percent and 12% of the patients presented with T2-4N0M0 and T2-4N1-3M0 stages, respectively, and 16% presented with synchronous metastases. The most frequent curative treatments were radical surgery and chemotherapy, sequential chemotherapy and radiation therapy, and radical surgery alone. The median (interquartile range, IQR) OS and DFS times were 12.9 months (IQR, 7-32 months) and 9 months (IQR, 5-23 months), respectively. The metastatic, T2-4N0M0, and T2-4N1-3M0 groups differed significantly (P=.001) in terms of median OS and DFS. In a multivariate analysis, impaired creatinine clearance (OS and DFS), clinical stage (OS and DFS), a Karnofsky performance status <80 (OS), and pure SCC histology (OS) were independent and significant adverse prognostic factors. In the patients with nonmetastatic disease, the type of treatment (ie radical surgery with or without adjuvant chemotherapy vs conservative treatment) did not significantly influence OS or DFS (P=.7). Conclusions: The prognosis for SCCB remains poor. The finding that radical cystectomy did not influence DFS or OS in the patients with nonmetastatic disease

    Full Text Available Purposes To examine the factors related to the choice of cytoreductive nephrectomy (CN for patients with metastatic clear cell renal cell carcinoma (mCCRCC, and compare the population-based survival rates of patients treated with or without surgery in the modern targeted therapy era. Materials and Methods From 2006 to 2009, patients with mCCRCC were identified from SEER database. The factors that affected patients to be submitted to CN were examined and propensity scores for each patient were calculated. Then patients were matched based upon propensity scores. Univariable and multivariable cox regression models were used to compare survival rates of patients treated with or without surgery. Finally, sensitivity analysis for the cox model on a hazard ratio scale was performed. Results Age, race, tumor size, T stage and N stage were associated with nephrectomy univariablely. After the match based upon propensity scores, the 1-, 2-, and 3-year cancer-specific survival rate estimates were 45.1%, 27.9%, and 21.7% for the no-surgery group vs 70.6%, 52.2%, and 41.7% for the surgery group, respectively (hazard ratio 0.42, 95%CI: 0.35-0.52, log-rank P<0.001. In multivariable Cox proportional hazard regression model, race, T stage, N stage and median household income were significantly associated with survival. Sensitivity analysis on a hazard ratio scale indicated that the hazard ratio might be above 1.00 only when the unknown factor had an opposite effect on survival which was 3-fold than CN. Conclusion The results of our study showed that CN significantly improves the survival of patients with metastatic CCRCC even in the targeted therapy era.

    Objective:To study the effect of radiotherapy on serum SCC, CEA, CRFRA21-1, TAG72, CA199 and lymphocyte subsets in patients with esophageal squamous cell carcinoma. Methods: A total of 60 patients with esophageal squamous cell carcinoma in our hospital from January 2013 to January 2016 were selected as experiment group and 40 healthy subjects were selected as control group. Patients in experiment group were treated with 6MV X-ray radiation therapy. Serum SCC, CEA, CRFRA21-1, TAG72, CA199 and the cell percentage of peripheral blood CD4+, CD8+ were compared in control group and the experimental group before and after 1 month radiotherapy.Results:Before treatment, the levels of serum SCC, CEA and CRFRA21-1 in the experimental group were significantly higher than those in the control group (P0.05). Before treatment, the cell percentage of peripheral blood CD4+, CD8+ and the ratio of CD4+/CD8+ in experimental group was significantly lower than that of the control group, the percentage of peripheral blood CD8+ in the experimental group was significantly higher than that in the control group (P0.05), and in the experimental group, the proportion of CD4+ cells and the tatio of CD4+/CD8+in peripheral blood was significantly lower than that of the control group, the proportion of CD8+ was significantly higher than that of the control group (P<0.05).Conclusions: Radiotherapy can significantly reduce the serum SCC, CEA, CRFRA21-1, TAG72 and CA199 levels of the patients with esophageal squamous cell carcinoma, but have less influence on the T lymphocyte subsets.

    Objective: To study the clinical pathological characteristics of ovarian metastasis of endometrial carcinoma and the factors affecting prognosis. Methods: Retrospective analysis was made to the clinical pathological outcome of endometrial carcinoma patients receiving surgical treatment in our hospital from January 1990 to December 2002. Results:Among the 191 cases of endometrial carcinoma patients, 17 cases (8.9%) had ovarian metastasis and young patients were more likely to have ovarian metastasis. The multiple factor analysis showed that the independent risk factors of ovarian metastasis in endometrial carcinoma included the depth of myometrial invasion, lymph node metastasis and pathological types. Conclusion: Ovarian metastasis in patients with endometrial carcinoma is associated with poor prognosis, the depth of myometrial invasion, lymph node metastasis and histologic types are independent risk factors affecting the prognosis. For young patients at early stage of the disease, it should be prudent as to whether to retain the ovary.

    Lung cancer is the principal cause of cancer-related death worldwide. The use of targeted therapies, especially tyrosine kinase inhibitors (TKIs), in specific groups of patients has dramatically improved the prognosis of this disease, although inevitably some patients will develop resistance to these drugs during active treatment. The most common cancer-associated acquired mutation is the epidermal growth factor receptor (EGFR) Thr790Met (T790M) mutation. During active treatment with targeted therapies, histopathological transformation to small-cell lung carcinoma (SCLC) can occur in 3-15% of patients with non-small-cell lung carcinoma (NSCLC) tumors. By definition, SCLC is a high-grade tumor with specific histological and genetic characteristics. In the majority of cases, a good-quality hematoxylin and eosin (H&E) stain is enough to establish a diagnosis. Immunohistochemistry (IHC) is used to confirm the diagnosis and exclude other neoplasia such as sarcomatoid carcinomas, large-cell carcinoma, basaloid squamous-cell carcinoma, chronic inflammation, malignant melanoma, metastatic carcinoma, sarcoma, and lymphoma. A loss of the tumor-suppressor protein retinoblastoma 1 (RB1) is found in 100% of human SCLC tumors; therefore, it has an essential role in tumorigenesis and tumor development. Other genetic pathways probably involved in the histopathological transformation include neurogenic locus notch homolog (NOTCH) and achaete-scute homolog 1 (ASCL1). Histological transformation to SCLC can be suspected in NSCLC patients who clinically deteriorate during active treatment. Biopsy of any new lesion in this clinical setting is highly recommended to rule out a SCLC transformation. New studies are trying to assess this histological transformation by noninvasive measures such as measuring the concentration of serum neuron-specific enolase.

    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.

    Full Text Available Abstract Background To evaluate oncological and clinical outcome in patients with renal cell carcinoma (RCC and tumor thrombus involving inferior vena cava (IVC treated with nephrectomy and thrombectomy. Methods We identified 50 patients with a median age of 65 years, who underwent radical surgical treatment for RCC and tumor thrombus of the IVC between 1997 and 2010. The charts were reviewed for pathological and surgical parameters, as well as complications and oncological outcome. Results The median follow-up was 26 months. In 21 patients (42% distant metastases were already present at the time of surgery. All patients underwent radical nephrectomy, thrombectomy and lymph node dissection through a flank (15 patients/30%, thoracoabdominal (14 patients/28% or midline abdominal approach (21 patients/42%, depending upon surgeon preference and upon the characteristics of tumor and associated thrombus. Extracorporal circulation with cardiopulmonary bypass (CPB was performed in 10 patients (20% with supradiaphragmal thrombus of IVC. Cancer-specific survival for the whole cohort at 5 years was 33.1%. Survival for the patients without distant metastasis at 5 years was 50.7%, whereas survival rate in the metastatic group at 5 years was 7.4%. Median survival of patients with metastatic disease was 16.4 months. On multivariate analysis lymph node invasion, distant metastasis and grading were independent prognostic factors. There was no statistically significant influence of level of the tumor thrombus on survival rate. Indeed, patients with supradiaphragmal tumor thrombus (n = 10 even had a better outcome (overall survival at 5 years of 58.33% than the entire cohort. Conclusions An aggressive surgical approach is the most effective therapeutic option in patients with RCC and any level of tumor thrombus and offers a reasonable longterm survival. Due to good clinical and oncological outcome we prefer the use of CPB with extracorporal

    Full Text Available Xp11 translocation renal cell carcinoma (TRCC is a rare subtype of renal cell carcinoma characterized by chromosomal translocations involving the TFE3 gene located at the Xp11.2 locus. Initial cases were more common in children, but cases in older adults have begun to accrue and suggest a relatively more aggressive course. We report a case of Xp11 TRCC in a 63-year-old female patient with initial presentation mimicking upper urinary tract urothelial cell carcinoma, with biopsy proving TRCC. She underwent a radical nephrectomy and paracaval lymph node dissection and is followed up with the intent to initiate vascular endothelial growth factor–targeted therapy in case of recurrence.

    Introducción: la detección de grupos de riesgo de cáncer oral permite reducir las tasas de morbilidad y mortalidad típicas de esta patología. Objetivo: se analizó el rol de carnes rojas, macronutrientes y micronutrientes en pacientes con carcinoma oral de células escamosas (COCE) en un estudio de casos y controles llevado a cabo en Córdoba, Argentina. Métodos: estudio de casos y controles 3:1, ambos sexos, con edades comprendidas entre 24-80 años. La información sobre la dieta fue recogida mediante un cuestionario de frecuencia de alimentos cuali-cuantitativo. La regresión logística se aplicó para evaluar la asociación entre el estado caso/control y la ingesta diaria de carne roja/ macronutrientes/micronutrientes/energía. Resultados: los micronutrientes y minerales de la dieta que mostraron valores medios significativos de consumo común en los casos relativos a los controles eran hierro, fósforo, vitaminas B1, B5, B6, E y K y selenio. La medición de la asociación estimada por regresión logística mostró una asociación significativa entre carne roja, grasas, energía diaria, fósforo, vitamina B5, vitamina E, ingesta de selenio y presencia de COCE. Conclusión: un alto consumo de grasas, fósforo, vitamina B5, vitamina E, selenio y carne roja parece estar relacionado con la presencia de COCE en Córdoba, Argentina. En relación con el consumo de carne roja y el riesgo de COCE, la investigación futura debería centrar su atención en la reducción de la complejidad de las relaciones de la dieta y la enfermedad, así como en reducir la variabilidad de los datos de ingesta mediante la estandarización de los criterios de admisión a fin de aplicar estrategias sencillas en salud pública para el reconocimiento de grupos de riesgo de COCE.

    Antecedentes: La determinación del gasto energético basal (GEB) es esencial para la planificación de la terapia nutricional en pacientes con cáncer de esófago. Objetivos: El objetivo de este estudio fue determinar GEB por calorimetría indirecta (CI) en pacientes con carcinoma de células escamosas del esófago (CCS). Métodos: Estudio transversal con 30 pacientes ingresados con el diagnóstico de CCS que se sometieron CI antes de iniciar la terapia contra el cáncer. La abeja se evaluó con CI y estimó por medio de la ecuación de Harris-Benedict (EHB). La evaluación nutricional se realizó utilizando los parámetros antropométricos (índice de masa corporal, circunferencia del brazo, el pliegue del tríceps, circunferencia muscular del brazo y pérdida de peso), parámetros bioquímicos (albúmina, transferrina y la proteína C-reactiva) y bioimpedancia tetrapolar para evaluar la composición corporal (grasa masa). Además, la capacidad pulmonar se midió y la estadificación clínica del cáncer establecido por el método TNM. Resultados: La media de la abeja para la ecuación CI y Harris-Benedict fueron 1421,8 ± 348,2 kcal / día y 1310,6 ± 215,1 kcal / día, respectivamente. No se encontró asociación entre GEB medido por CI y la estadificación clínica (p = 0,255) o el índice Tiffeneau (p = 0,946). No se encontraron asociaciones significativas entre GEB medidos por dosis de CI y alteración de la transferrina, albúmina y proteína C reactiva (p = 0,364, 0,309 y 0,780, respectivamente). Los factores más asociados con GEB fueron el IMC y la masa libre de grasa. Conclusión: La abeja de los pacientes con CCS fue subestimada cuando se utiliza el EHB, y el resultado sobreestimado cuando se incorpora un factor de d2013 con el EHB. Por lo tanto, a pesar de las dificultades de aplicación práctica de CI, su uso debe ser considerado.

    The patient was a 77-year-old male former smoker, with history of several basal cell carcinomas (BCCs) in sun-protected areas around the waistline, who presented with another small ulceration on the anterior right upper scrotum near the base of the penis. BCC was suspected clinically and the lesion was treated with cryosurgery. The tumor recurred, became raised, and began to bleed. An excisional biopsy was performed. It showed nodular BCC surrounded by a cellular proliferation of round histiocytic cells with convoluted, lobulated and reniform nuclei and abundant cytoplasm . The patient had no history of exposure to ionizing radiation, chemotherapy, immunosuppressive medications, prior lymphoma or other malignancy. However, he spent 4 years on a ship loading coal into the furnace of a steam engine, during which he slept in adjacent quarters that were covered with coal dust. Additionally, he had a several-year history of occupational skin exposure to machine oil, oil refinery waste, sulfur waste, hydraulic fluid, and asbestos. He also reported a history of nude sunbathing. The scrotal lesion was re-excised and the patient remains disease-free more than 1 year after the diagnosis.

    Full Text Available The prognostic value of mTOR in ESCC is much controversial; this study aimed to determine the prognostic importance of mTOR and PTEN in patients with ESCC. A total of 148 consecutive patients who underwent esophagectomy from 2010 to 2012 were included in this study, tested by western bolt and immunohistochemistry for mTOR and PTEN expression. Correlation coefficient was calculated using Pearson’s correlation test. The 3-year overall survival (OS and disease-free survival (DFS were calculated in relation to the two markers. 94 (63.5% of 148 were mTOR high expression, and PTEN high expression was detected in 46 (31.1% of the 148 patients with ESCC. The Pearson correlation coefficient revealed a significant negative correlation in two proteins (correlation coefficient = −0.189, P<0.005. The 3-year OS and DFS time in the mTOR-high group was 23.9 and 18.4 months, respectively, and the time in the mTOR-low group was 33.9 months and 31.4 months, respectively. The difference of survival rate between the two groups remained statistically significant. mTOR-low or PTEN-high patients had better 3-year rates of OS and DFS than mTOR-high or PTEN-low group (P<0.001 by the log-rank test. This study also found that mTOR was an independence prognostic factor by multivariate analysis.

    Circulating tumor cells (CTCs) quantification may be helpful for evaluating cancer dissemination, predicting prognosis and assessing therapeutic effectiveness and safety. In the present study, CTCs from blood samples of 72 patients with hepatocellular carcinoma (HCC) were enriched with anti-EpCAM nanoparticles. AFP mRNA level was detected by nested polymerase chain reaction (PCR) after enrichment of CTCs from HCC blood samples at 0, 3, 6, 9 and 12 months after hepatectomy, respectively. AFP mRNA expression in CTCs was positive in 43 patients (59.7%) and negative in 29 patients (40.3%) before hepatectomy. Among 43 patients with positive AFP mRNA expression in CTCs before hepatectomy, 10 and 11 were diagnosed as intrahepatic/extrahepatic metastasis before and after hepatectomy, respectively. In addition, these 21 patients with metastasis had persisting positive AFP mRNA of CTCs during the whole tested year. Specifically, 3 patients with AFP mRNA negative in CTCs before hepatectomy changed to be positive at 6 and 9 months, and 2 of them were diagnosed as metastasis 12 months after hepatectomy. We conclude that the positive AFP mRNA of CTCs can be a pivotal predictor for HCC metastasis before and after hepatectomy. The release of AFP expression from hepatocellular carcinoma cells into circulation must be a major source of HCC metastasis.

    Previous investigations in our laboratory and others (Chen et al., 1998) have shown that the levels of certain inflammatory, proangiogenic cytokines in saliva and tissue specimens of patients with oral premalignant lesions (OPML) are elevated. We have also shown that these cytokines are elevated in tissue culture of oral squamous cell carcinoma (OSCC) cell lines. The purpose of this pilot study was to determine the level of several inflammatory, NF-kappaB-dependent cytokines in whole unstimulated saliva (WUS), in subjects with OPML as compared to those with diagnosed OSCC. Subjects (n=13) with OMPL, OSCC (n=13), and age-sex matched controls without oral lesions (C) (n=13) were enrolled. The mean age was 58.7 years. WUS was collected by standard techniques for 5 min (Navazesh, 1993). WUS samples were centrifuged and the cytokine analysis was performed on the supernatants by ELISA as previously described by Ondrey et al. (1991). The cytokines analyzed were: TNF-alpha, interleukin-1, interleukin-6, and interleukin-8 (TNF-alpha, IL-1, IL-6, and IL-8). The results as analyzed by Pairwise t-tests revealed significant differences in the salivary levels of: (1) TNF-alpha: (mean+/-S.E.M.: TNF-alpha-OSSC=28.9+/-14.6* pcg/ml versus OPML=10.5+/-7.4* pcg/ml versus controls=3.0+/-1.0 pcg/ml; *p<0.01); (2) IL-1: (IL-1-OSSC=454.4+/-215.8* pcg/ml versus OPML=255.1+/-124.8* pcg/ml versus controls=173.2+/-66.9 pcg/ml; *p<0.01); (3) IL-6: (mean+/-S.E.M.: IL-6-OSSC=88.2+/-43.2* pcg/ml versus OPML=70.8+/-24.3* pcg/ml versus controls=1.4+/-1.0 pcg/ml; *p<0.001) and (4) IL-8 in saliva: (mean+/-S.E.M.: IL-8-OSSC=3154.1+/-1023.2* pcg/ml versus OPML=1918.2+/-899.1* pcg/ml versus controls=1580.7+/-789.0 pcg/ml; *p<0.001). There was a significant increase in the levels of all cytokines in the saliva of the OPML as compared to controls, and a significant difference in the cytokines of OSSC saliva compared to the OPML and controls. These results suggest that these proangiogenic, proinflammatory

    AIM: To determine the incidence of brain metastasis in a contemporary group of patients with carcinoma of the esophagus. METHODS: Retrospective analysis of 53 patients with esophageal carcinoma who received radiotherapy as a component of treatment between 1998 and 2007, including patient and tumor characteristics, and subsequent diagnosis of brain metastasis. The association between the histological type of esophageal cancer and the incidence of brain metastasis was assessed using Fisher's exact test. RESULTS: Forty-four of the fifty-three patients in this study had adenocarcinoma and nine had squamous cell carcinoma, ranging from stage ⅡA-ⅣB. Primary treatment was surgery with neoadjuvant chemoradiotherapy (trimodality therapy) in 19% of patients; chemoradiotherapy in 42%; and surgery and adjuvant radiotherapy in 7%. Twenty-five percent of patients in this study received palliative radiotherapy. The overall incidence of brain metastasis in this cohort was 13%. Adenocarcinoma was the primary tumor histology in all of the patients who developed brain metastasis, representing an incidence of 16% in this subgroup. No patients with squamous cell carcinoma received trimodality therapy. The association between histology and brain metastasis was not statistically significant. CONCLUSION: The incidence of brain metastasis in this contemporary cohort of patients with esophageal carcinoma is higher than previously reported and was confined to those with adenocarcinoma.

    A 55-year-old man with a history of acute myeloid leukaemia treated with hematopoietic stem cell transplantation and with a 5-year history of bisphosphonate-related osteonecrosis of the jaws, following 12 cycles of intravenous zoledronic acid therapy, presented in December 2009 with a history of increasingly severe unilateral lower jaw pain. Oral examination revealed, as previously, exposed bone in the left mandible, but also a new exophytic mass on the lower-left buccal mucosa. Biopsy confirmed a diagnosis of oral squamous cell carcinoma. To the best of our knowledge, this is the first report of an oral squamous cell carcinoma that appeared adjacent to an area of osteochemonecrosis.

  5. 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 To reveal the specific features of hematopoiesis in patients with head and neck squamous cell carcinoma (HNSCC, the authors analyzed the indicators of 41 bone marrow aspirates in relation to the clinical and morphological characteristics of the tumor and micrometastases detected in bone marrow. Puncture samples were morphologically and molecularly examined at the Laboratory of Hematopoiesis Immunology, N.N. Blokhin Russian Cancer Research Center. The found changes in the bone marrow cell composition in HNSCC patients showed themselves as an increase in the relative count of segmented neutrophils and a decrease in the level of immature granulocytes with no alternations in the neutrophil maturation index and in the percentage of granulocyte lineage cells. Bone marrow hypocellularity is a characteristic feature of high-grade HNSCC. The significantly enhanced leuko-erythroblastic ratio was due to a reduction in red blood cells: the erythroid cell maturation index rose, by increasing the percentage of bone marrow oxyphilic normoblasts in patients with locally advanced HNSCC. A highly sensitive method for detecting mRNA of the specific squamous cell carcinoma protein E48 was perfected using reverse-transcription polymerase chain reaction and Southern blotting, followed by an enzyme immunoassay that could recognize bone marrow micrometastases in 35 % of the patients with HNSCC. The patients with found bone marrow micrometastases showed a significant decrease in the proportion of polychromatophilic normoblasts and a significant increase in granulocytes in the presence of normal values of lymphocytes and other cellular elements of myelograms. It was established that in the presence of regional lymph node involvement, bone marrow micrometastases were significantly more frequently in the patients with HNSCC and tumor progression over a period of up to 9 months.

    Background The coagulation function in patients with pancreatic carcinoma is abnormal and the reason is not very clear. In this study, we retrospectively analyzed the coagulation function in patients with pancreatic carcinoma.Methods From June 2004 to December 2007, 132 patients received diagnosis and treatment in our hospital. The coagulative parameters including the prothrombin time, activated partial thromboplastin time, and fibrinogen levels were collected and studied retrospectively.Results The average fibrinogen levels in patients with pancreatic carcinoma, (476.21±142.05) mg/dl, were significantly higher than in patients with cholangiolithiasis, (403.28±126.41) mg/dl (P 0.05).Conclusions The level of fibrinogen in patients with pancreatic carcinoma was elevated. The elevated fibrinogen level may be associated with invasiveness and lymphatic metastasis. Using vitamin K in perioperation management did not reduce intraoperative blood loss.

    Peritoneal carcinoma is a rare primary tumor, described in the literature almost exclusively in women. This report describes our clinicopathological findings in a 51-year-old male patient with peritoneal carcinoma and ascites. Pathologic studies included routine histology, immunohistochemistry and electron microscopy on biopsy and autopsy tumor tissue. After chemotherapy, the patient achieved a complete remission twice, lasting for 14 months and 8 months, respectively, and died after 3 years. His clinical course was similar to that of female patients with peritoneal carcinoma or advanced ovarian cancer. Our case confirms the existence of primary peritoneal carcinoma in males. In addition, it shows that this entity responds to the same chemotherapy as used for ovarian cancer and primary peritoneal carcinoma in females.

    We report the CT findings of four cases of squamous cell carcinoma, paying special attention to the epicenter of the lesion and the pattern of bony destruction. All four patients had a past history of chronic otitis media. Squamous cell carcinoma affected mainly the hypotympanum and inferior wall of the external auditory canal. and in all cases revealed an irregular pattern of bony destruction. Irregular destruction of the tegmen tympani occurred in two cases. In cases of squamous cell carcinoma, CT findings suggesting involvement of the promontory are usually noted. (author)

  14. Tumor-specific hypermethylation of epigenetic biomarkers, including SFRP1, predicts for poorer survival in patients from the TCGA Kidney Renal Clear Cell Carcinoma (KIRC project.

    Directory of Open Access Journals (Sweden)

    Christopher J Ricketts

    Full Text Available The recent publication of the TCGA Kidney Renal Clear Cell Carcinoma (KIRC project has provided an immense wealth and breadth of data providing an invaluable tool for confirmation and expansion upon previous observations in a large data set containing multiple data types including DNA methylation, somatic mutation, and clinical information. In clear cell renal cell carcinoma (CCRCC many genes have been demonstrated to be epigenetically inactivated by promoter hypermethylated and in a small number of cases to be associated with clinical outcome. This study created two cohorts based on the Illumina BeadChip array used to confirm the frequency of tumor-specific hypermethylation of these published hypermethylated genes, assess the impact of somatic mutation or chromosomal loss and provide the most comprehensive assessment to date of the association of this hypermethylation with patient survival. Hypermethylation of the Fibrillin 2 (FBN2 gene was the most consistent epigenetic biomarker for CCRCC across both cohorts in 40.2% or 52.5% of tumors respectively. Hypermethylation of the secreted frizzled-related protein 1 (SFRP1 gene and the basonuclin 1 (BNC1 gene were both statistically associated with poorer survival in both cohorts (SFRP1 - p = <0.0001 or 0.0010 and BNC1 - p = <0.0001 or 0.0380 and represented better independent markers of survival than tumor stage, grade or dimension in one cohort and tumor stage or dimension in the other cohort. Loss of the SFRP1 protein can potentially activate the WNT pathway and this analysis highlighted hypermethylation of several other WNT pathway regulating genes and demonstrated a poorer survival outcome for patients with somatic mutation of these genes. The success of demethylating drugs in hematological malignances and the current trials in solid tumors suggest that the identification of clinically relevant hypermethylated genes combined with therapeutic advances may improve the effectiveness and

    AIM: To assess the accuracy of ultrasound combined with fine-needle aspiration cytology (FNAC) in the detection of lymph node metastasis in patients with squamous cell carcinoma of the vulva. MATERIALS AND METHODS: The groin nodes of 44 consecutive patients with primary squamous cell carcinoma of the vulva undergoing groin node dissection were assessed with ultrasound and FNAC. The results were compared with histology from subsequent inguinofemoral lymph node dissection. Twenty-nine patients underwent bilateral groin node dissections and 15 unilateral providing comparable data for 73 groins. RESULTS: Histology demonstrated metastatic disease in 28 groins and no evidence of metastatic disease in 45. Ultrasound agreed with the histology in 67 of the 73 groins (92%), with two false-positives, four false-negatives and two indeterminate appearances. Cytology agreed with the histology in 65 of 72 FNAC samples obtained (90%), with six false-negatives, and one indeterminate result. No false-positive cytology results were seen. Ultrasound and FNAC together failed to detect metastatic disease in four groins, one with an indeterminate ultrasound appearance, another with indeterminate cytology, the two others each having a single positive inguinal node despite a negative ultrasound and FNAC. CONCLUSION: The combination of ultrasound and FNAC provides a sensitive and specific tool for pre-operative assessment and may prevent unnecessary groin dissection and the attendant morbidity in selected patients with vulval cancer.

    Objective To discuss treatment options for tonsillar squamous cell carcinoma.Methods A total of 108 patients with biopsy-proven tonsillar squamous cell carcinoma, treated between 1984 and 2000, were reviewed, including 82 men and 26 women, with ages ranging from 19 to 70 years. Treatments consisted of either radiotherapy and surgery reserved as salvage treatment (Salvage Surgery, 83 patients), or planned surgery with preoperative radiation (Planned Surgery, 25 patients). Radiotherapy was delivered primarily in a dosage of 60-70 Gy for Salvage Surgery patients and 40-50 Gy for Planned Surgery patients. Both salvage and planned surgeries were radical, with resection of the lateral oropharyngeal wall, segmental resection of the mandible and neck dissection. The pectoralis major myocutaneous flaps were used to repair surgical defects. Results The percentages of radical surgery used in the Salvage Surgery and Planned Surgery groups were 24.1% (20/83) and 88.0% (22/25), respectively (P=0.000). The local recurrence rates were 28.9% (24/83) and 20.0% (5/25) in the Salvage Surgery and Planned Surgery groups, respectively (P= 0.378). The neck recurrence rates were 9.6% (8/83) and 8.0% (2/25) in the Salvage Surgery and Planned Surgery groups respeatively (P= 0.804). The 5-year survival rates were 59.3% and 55.3% in the Salvage Surgery and Planned Surgery groups, respeatively (P= 0.7056).Conclusions Although the two treatments had a similar survival rate, Salvage Surgery avoided 60% commando operations compared with the Planned Surgery group, which benefits to recovery of oral functions. Primary radiotherapy is recommended as the treatment of choice for tonsillar squamous cell carcinoma. After radical radiotherapy, salvage surgery should be undertaken in the case of tumor remnants or recurrences.

    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.

    About 400,000 people worldwide are diagnosed with oral squamous cell carcinoma (SCC) annually, and the incidence is increasing. Many advanced carcinomas of the oral cavity require radical surgical treatment that can impair patient's quality of life (QoL) and severity of symptoms. We therefore aimed to identify coping strategies and disease-specific medical factors that affect QoL and severity of symptoms. Patients with oral SCC were asked to complete the Freiburg Questionnaire on Coping with Illness (FQCI), the University of Washington Quality of life Questionnaire (UW-QOL version 4), and the Brief Symptom Inventory (BSI) to measure psychological stress. We also assessed the impact of various factors on QoL and severity of symptoms, including stage and site of tumour, method of reconstruction, time of diagnosis, and social structure (age, sex, marital status, living arrangements, level of education, and employment). We enrolled a consecutive sample of 104 patients over a period of one year. Stepwise linear regression analyses indicated that both depressive coping and size of tumour had an adverse effect on QoL and severity of symptoms. Patients with high educational attainment and those who lived alone reported impaired QoL, and women experienced increased severity of symptoms. Impaired QoL and increased severity of symptoms were associated with a depressive style of coping, size of tumour, educational attainment, and living arrangements. It is important to identify these patients during treatment as they could benefit from psycho-oncological counselling.

    Although obesity increases the risk of renal cell carcinoma (RCC), obese patients with RCC experience longer survival than non-obese patients. However, the mechanism of this “obesity paradox” is unknown. We examined the impact of preoperative BMI, serum total adiponectin (sAd) level, total adiponectin secretion from perinephric adipose tissue, and intratumoral expression of adiponectin receptors on RCC aggressiveness and survival. We also investigated the mechanism underlying enhanced cancer aggressiveness in RCC cells stimulated with exogenous adiponectin. Overweight and obese patients had significantly lower grade cancers than normal patients in all patients and in those without metastasis (p = 0.003 and p = 0.027, respectively). Cancer-specific survival was significantly longer in overweight and obese patients than in normal patients in all patients (p = 0.035). There was a weak inverse correlation between sAd level and BMI in RCC patients (r = −0.344, p = 0.002). Tumor size was slightly correlated with sAd level, and high sAd was significantly associated with poor overall survival rates in patients with non-metastatic RCC (p = 0.035). Adiponectin levels in perinephric adipose tissue and intratumoral AdipoR1/R2 expression were not correlated with RCC aggressiveness or survival. Proliferation significantly increased in 786-O and Caki-2 cells exposed to exogenous adiponectin, whereas cell invasion and migration were unaffected. In addition, exogenous adiponectin significantly inhibited starvation- and metformin-induced apoptosis, and up-regulated p-AMPK and Bcl-xL levels. In summary, low BMI and high adiponectin levels are associated with aggressive cell behaviors and poor survival in surgically-treated RCC patients. The effects of adiponectin on proliferation and apoptosis might underlie the “obesity paradox” of RCC. PMID:28178338

    2008-08-01

    Full Text Available Abstract Introduction The etiology of seizure disorders in lung cancer patients is broad and includes some rather rare causes of seizures which can sometimes be overlooked by physicians. Paraneoplastic limbic encephalitis is a rather rare cause of seizures in lung cancer patients and should be considered in the differential diagnosis of seizure disorders in this population. Case presentation This case report describes the new onset of seizures in a 64-year-old male patient receiving chemotherapy for a diagnosed stage IV non-small cell lung carcinoma. After three cycles of therapy, he was re-evaluated with a chest computed tomography which showed a 50% reduction in the tumor mass and in the size of the hilar and mediastinal lymphadenopathy. Twenty days after the fourth cycle of chemotherapy, the patient was admitted to a neurological clinic because of the onset of self-limiting complex partial seizures, with motionless stare and facial twitching, but with no signs of secondary generalization. The patient had also recently developed neurological symptoms of short-term memory loss and temporary confusion, and behavioral changes. Laboratory evaluation included brain magnetic resonance imaging, magnetic resonance spectroscopy of the brain, serum examination for 'anti-Hu' antibodies and stereotactic brain biopsy. Based on the clinical picture, the patient's history of lung cancer, the brain magnetic resonance imaging findings and the results of the brain biopsy, we concluded that our patient had a 'definite' diagnosis of paraneoplastic limbic encephalitis and he was subsequently treated with a combination of chemotherapy and oral steroids, resulting in stabilization of his neurological status. Despite the neurological stabilization, a chest computed tomography which was performed after the 6th cycle showed relapse of the disease in the chest. Conclusion Paraneoplastic limbic encephalitis is a rather rare cause of new onset of seizures in patients with

    Basalomatosis is an uncommon skin condition characterized by the occurrence of multiple basal cell carcinomas. Many cases reported in the literature have been attributed to arsenic treatment in psoriasis patients. We report a patient with basalomatosis caused by cobalt-60 ({sup 60}Co) irradiation. A 55-year-old farmer developed 43 basal cell carcinomas 20 years after treatment of an immuno-blastoma with {sup 60}Co irradiation. All the tumours were located within the radiation fields. Other possible causes of basalomatosis, such as arsenic intoxication and basal cell naevus syndrome, were excluded. The patient`s multiple superficial basal cell carcinomas probably represent a late adverse effect of the {sup 60}Co irradiation. (Author).

    Although radical nephrectomy alone is widely accepted as the standard of care in localized treatment for renal cell carcinoma (RCC), it is not sufficient for the treatment of metastatic RCC (mRCC), which invariably leads to an unfavorable outcome despite the use of multiple therapies. Currently, sequential targeted agents are recommended for the management of mRCC, but the optimal drug sequence is still debated. This case was a 57-year-old man with clear-cell mRCC who received multiple therapies following his first operation in 2003 and has survived for over 10 years with a satisfactory quality of life. The treatments given included several surgeries, immunotherapy, and sequentially administered sorafenib, sunitinib, and everolimus regimens. In the course of mRCC treatment, well-planned surgeries, effective sequential targeted therapies and close follow-up are all of great importance for optimal management and a satisfactory outcome.

    Cancer cells exhibit characteristic damage of DNA and its expression. The expression of the tumor suppressors E-cadherin and p27(Kip1) has been tested on 57 head and neck squamous cell carcinomas (HNSCC) of Indonesian subjects. HNSCC tumor samples including both primary and (unrelated) nodal cases were obtained from the archives of Indonesian hospitals, in accordance with acknowledged ethical requirements. Only modest correlation was found between reduced expression of E-cadherin or p27(Kip1) with increased malignancy of primary and nodal growth. The observed strong correlation regardless of malignancy between the expressed levels of E-cadherin and p27(Kip1) suggests that also in combination these would not help to better predict the outcome of HNSCC.

    OBJECTIVE To conduct a comparative study of the effects of treatment using microwave ablation versus surgical resection on hematogenous dissemination of cancer cells, and on the level of immune cells of the peripheral blood in patients with small primary hepatocellular carcinoma (PHC, ≤5 cm).METHODS Forty patients with small PHC (maximal diameter ≤5 cm) were divided into a microwave group (19 cases) and a surgical operation group (21 cases). A real-time (RT) quantitative nested RT-PCR examination was performed for peripheral blood alpha-fetoprotein (AFP) mRNA. Studies were conducted to determine the level of CD3, CD4, CD8 and CD4/CD8 cells and for liver function at 30 min before, and 30 min,1 day and 3 days after the treatment.RESULTS Compared to the value before ablation, no obvious changes of CD3, CD4, CD8 and CD4/CD8 cells were found in patients of the microwave group within 7 days after ablation, but CD3, CD4 and CD4/CD8 cells in the operation group were lower compared to that before operatioh. The copy number of AFP mRNA in the peripheral blood samples of the patients of the 2 groups before operation was determined in 67.5% of the patients (27/40). There was an rise in the expression after treatment but no statistical difference was found in comparing the 2 groups. Follow-up of the patients was conducted for 1 to 16 months. For patients with continuous expression of peripheral blood AFP mRNA, the possibility of relapse and metastasis was increased.CONCLUSION Surgical resection or microwave ablation can cause more exfoliation of hepatoma carcinoma cells in the peripheral blood of patients with small PHC. The immune function of peripheral blood cells decreased in the patients after surgical resection, however, the immune function was better protected following microwave ablation. Microwave ablation causes minor reduction in liver function, and the treatment method presents a definite value for PHC therapy.

    Background 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. Objectives 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). Methods Glycosaminoglycans were quantified by electrophoresis and indirect ELISA method. The heparanase expression was analyzed by quantitative RT-PCR (qRTPCR). Results 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. Conclusion 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.

    Objective:To explore the effect of video-assisted thoracoscopic surgery (VATS) and traditional open surgery (TOS) on the inflammatory cytokine and immune function in patients with non-small cell lung carcinoma.Methods: A total of 68 patients with non-small cell lung carcinoma were included in the study and divided into VATS group and TOS group according to different surgical methods with 34 cases in each group. The operation time, intraoperative amount of bleeding, incision length, and lymph node dissection number after operation in the two groups were compared. The levels of serum IL-6 and CRP after operation in the two groups were detected and compared. The immunological function status before and after operation in the two groups was analyzed.Results: The operation time and intraoperative amount of bleeding in VATS group were significantly reduced, and the incision length was significantly shortened when compared with TOS group. IgG, CD4+, and CD8+ levels, and CD4+/CD8+ after operation in the two groups were significantly reduced when compared with before treatment, and those in TOS group were significantly lower than those in VATS group. IL-6 and CRP levels 1d after operation in the two groups were significantly elevated when compared with before operation, and those in TOS group were significantly higher than those in VATS group. IL-6 and CRP levels 5d after operation in VATS group were not significantly different from those before operation, while those in TOS group were significantly elevated when compared with before operation.Conclusions:VATS in the treatment of non-small cell lung carcinoma has a significant efficacy, can significantly alleviate the inflammatory reaction, and is beneficial to protect the immunological function.

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 Objective: to investigate the role of CD- 44 immunohistochemical expression within tumoural and non-tumoural tissue, aiming to understand if it can help us to predict the need of performing inguinal lymph nodes dissection to complete surgery of the penis. Materials and methods: CD44 immunohistochemical expression was investigated in tissue specimens from 39 patients with squamous cell carcinoma of the penis who underwent partial or total penectomy between 1987 and 2008. Patient age, tumour size, and grade; CD44 intensity score, cytological expression, topographic and distribution pattern were evaluated by immunohistochemistry on archived material and correlated with disease-specific survival. Results: mean patients age was 67.7 years; mean followup was 130.44 months. Bilateral inguinal lymphadenectomy was performed in 14 patients; there were 8 N+ patients (23.5%. pTis-pT1 vs. > pT1 and the EAU classification of risk group resulted to be predictive of lymph nodal metastases at univariate analysis (respectively p = 0.006 and p = 0.045, but not the grading. The intensity score, cytological expression, topographic and distribution pattern of CD44 staining did not correlate with stage, grade and lymph nodes metastases. All disease related deaths occurred only in patients showing an high CD44 intratumoral expression, but this correlation is not statistically significant. Multivariate analysis showed that only lymph node metastasis was an independent prognostic factor predictive of lymph nodes metastases. Conclusions: CD44 expression in patients with squamous cell carcinoma of the penis is not able to predict the need of performing inguinal lymphadenectomy; staging and the EAU classification of risk group resulted to be predictive of lymph nodal metastases.

    Comprehensive genomic characterizations of lung squamous cell carcinoma (LSCC) have been performed, but the differences between smokers (S-LSCC) and never smokers (NS-LSCC) are not clear, as NS-LSCC could be considered as a different disease from S-LSCC. In this study we delineated genomic alterations in a cohort of 21 NS-LSCC and 16 S-LSCC patients, and identified common gene mutations and amplifications as previously reported. Inclusion of more NS-LSCC patients enabled us to identify unreported S-LSCC- or NS-LSCC-specific alterations. Importantly, an amplification region containing FGF19, FGF3, FGF4 and CCND1 was found five-times more frequent in S-LSCC than in NS-LSCC. Amplification of FGF19 was validated in independent LSCC samples. Furthermore, FGF19 stimulated LSCC cell growth in vitro. These data implicate FGF19 as a potential driver gene in LSCC with clinic characteristics as smoking.

    Full Text Available Abstract Introduction The occurrence of multiple primary cancers is rare. Only a few cases and patient reviews of an association of triple malignancy have been reported. Case presentation We report here a case of a 78-year-old Moroccan woman presenting initially with a synchronous double malignancy, the first in her cervix and the second in her skin. Our patient was treated with radiation therapy for both tumors and remained in good control for 17 years, when she developed a metastatic disease from a neuroendocrine carcinoma of an unknown primary site. Conclusions Although the association of multiple primary cancers can be considered a rare occurrence, improving survival in cancer patients has made this situation more frequent.

    Cynthia A Batchelder

    Full Text Available Renal cell carcinomas arise from the nephron but are heterogeneous in disease biology, clinical behavior, prognosis, and response to systemic therapy. Development of patient-specific in vitro models that efficiently and faithfully reproduce the in vivo phenotype may provide a means to develop personalized therapies for this diverse carcinoma. Studies to maintain and model tumor phenotypes in vitro were conducted with emerging three-dimensional culture techniques and natural scaffolding materials. Human renal cell carcinomas were individually characterized by histology, immunohistochemistry, and quantitative PCR to establish the characteristics of each tumor. Isolated cells were cultured on renal extracellular matrix and compared to a novel polysaccharide scaffold to assess cell-scaffold interactions, development of organoids, and maintenance of gene expression signatures over time in culture. Renal cell carcinomas cultured on renal extracellular matrix repopulated tubules or vessel lumens in renal pyramids and medullary rays, but cells were not observed in glomeruli or outer cortical regions of the scaffold. In the polysaccharide scaffold, renal cell carcinomas formed aggregates that were loosely attached to the scaffold or free-floating within the matrix. Molecular analysis of cell-scaffold constructs including immunohistochemistry and quantitative PCR demonstrated that individual tumor phenotypes could be sustained for up to 21 days in culture on both scaffolds, and in comparison to outcomes in two-dimensional monolayer cultures. The use of three-dimensional scaffolds to engineer a personalized in vitro renal cell carcinoma model provides opportunities to advance understanding of this disease.

  2. Energy and protein intake and nutritional status in non-surgically treated patients with small cell anaplastic carcinoma of the lung

    Energy Technology Data Exchange (ETDEWEB)

    Enig, B.; Winther, E.; Hessov, I.

    The spontaneous food intake and nutritional status was assessed in 23 patients with small cell anaplastic carcinoma of the lung before and two times during a treatment period of 6 weeks. Radiation therapy was given for 2 weeks followed by a course of chemotherapy and another 2 weeks of radiation therapy. The energy intake decreased during the treatment from 146 to 130 per cent of basal metabolic rate. The protein intake remained unchanged (mean 0.9 g/kg body weight). There were insignificant and small losses of weight, body fat, free body mass and arm muscle circumference, and no changes were seen in serum albumin and serum transferrin. However, 6 patients suffered a weight loss of 5 per cent or more. No correlation existed between the nutritional parameters measured before treatment and the changes during treatment. Patients who suffered a loss of body weight could therefore not be singled out before the treatment.

    Full Text Available Merkel cell carcinoma is a rare, aggressive, malignant cutaneous tumor. It usually appears on the sun-exposed areas such as the head and neck in the elderly. A 72-year-old female patient was admitted to our clinic with the complaints of a big mass on her face. She described that the mass on her left cheek rapidly grew in three months. Her family and own medical history was unremarkable for skin cancers. On physical examination, there were no pathological findings except for a palpable submandibular lymphadenopathy. Dermatological examination revealed a giant tumoral lesion 9x9 cm in diameter, containing crusted and ulcerated areas on her left cheek. Histopathological examination of the specimen obtained from the lesion showed a neoplastic infiltration consisting small, atypic cells with big, round, hyperchromatic nucleus, narrow cytoplasms, and prominent nucleoulus in some areas, showing high mitotic activity. The neoplasm, which had apoptotic bodies and necrobiosis, also invaded the full thickness of the skin, and the epidermis was very thin. In immunochemistry, CK20 was strongly positive, S100 was focally positive, and EMA was positive, while synaptophysin, chromogranin, vimentin, CD3, CD20, as well as CD45, and CD99 were all negative. Based on these findings, the patient was diagnosed as having Merkel cell carcinoma. On the systemic screening for metastases, nodular lesions in the lungs compatible with metastases were detected on computed tomography. By the consultations with plastic and reconstructive surgeons and oncologists, she was accepted as inoperable and etoposide monotherapy was administered. In this report, we aimed to underline the importance of early diagnosis while presenting a case of giant Merkel cell carcinoma which shows an aggressive progression with lung metastases.

    Recent developments in chemotherapy have resulted in several new drug treatments for metastatic renal cell carcinoma (RCC). These therapies have shown improved progression-free survival and are applicable to many more patients than the conventional cytokine-based treatments for metastatic RCC. Consequently imaging is playing a greater part in the management of such patients. Computed tomography (CT) remains the primary imaging modality with other imaging modalities playing a supplementary role. CT is used in the diagnosis and staging of metastatic RCC. It is used in the follow-up of patients after nephrectomy, in assessing the extent of metastatic disease, and in evaluating response to treatment. This review looks at the role of CT in patients with metastatic RCC and describes the appearances of metastatic RCC before and following systemic therapy.

    @@ Transitional cell carcinoma (TCC) of bladder is the most common malignant tumor in uropoiesis system. Up to date, there is still lack of an ideal marker for the diagnosis of TCC except CT and MRI imaging and cystoscopy. Cystoscopy is an invasive examination, which increases the possibility of urinary tract infection. Urine cytology has low sensitivity (21%-40%) in diagnosis of bladder cancer, especially for those with medium or high differentiation. The specificity is often affected by factors such as specimen collection, urinary tract infection, etc. Detecting the expression of survivin mRNA in urine by real time-PCR is simple in specimen collection and is sensitive and relatively specific, which provides a simple and noninvasive diagnostic method for TCC. Moreover it allows comparing the gene expression levels at different stages and grades of TCC, which can help define malignancy degree of TCC.

    Full Text Available Buccal carcinoma is one of the most common oral malignant neoplasms, especially in the South Asian region. Radiotherapy, which plays a significant role in the treatment of this carcinoma, has severe adverse effects. Different types of prosthesis may be constructed to protect healthy tissues from the adverse effects of treatment and concentrate radiation in the region of the tumor mass. However, the technique for fabrication of shielding stent with Lipowitz's alloy (cerrobend/Wood's alloy has not been well documented. This article describes detailed technique for fabrication of such a stent for unilateral buccal carcinoma patients to spare the unaffected oral cavity from potential harmful effects associated with radiotherapy.

Patients and methods: A total of 327 patients with advanced renal cell carcinoma and mRCC who received targeted therapy in two Chinese clinical centers were analyzed retrospectively. The patients were stratified into three groups: young (aged <45 years, middle-aged (aged 45–64 years, and old (aged ≥65 years. Overall survival (OS and progression-free survival (PFS curves were drawn using the Kaplan–Meier method, and Cox's proportional hazard regression model was used to compare OS and PFS within age groups. Results: There were no significant differences among young, middle-aged, and old groups in terms of OS (P=0.087, whereas PFS in the old group was significantly better than in the young and middle-aged groups (P=0.043. Both OS and PFS in the younger groups (aged <65 years were significantly worse than in the old group (age ≥65 years; median OS, 28.1 vs 28.7 months [P=0.029]; median PFS, 11.4 vs 14 months [P=0.015]. No difference in OS or PFS was found between the young and middle-aged groups.

    Androgen-independent, human prostate carcinoma cells (DU145) develop into solid, carcinomatous xenotransplants on the diaphragm of nu/nu mice. Tumors encompass at least two poorly differentiated cell types: a rapidly dividing, eosinophilic cell comprises the main cell population and a few, but large basophilic cells able to invade the peritoneal stroma, the muscular tissue, lymph vessels. Poor cell contacts, intracytoplasmic lumina, and signet cells are noted. Lysosomal activities are reflected by entoses and programmed cell deaths forming cribriform carcinomas. In large tumors, degraded cells may align with others to facilitate formation of blood supply routes. Malignant cells would spread via ascites and through lymphatics.

    Full Text Available Background. In general, younger age is associated with better survival in patients with colon cancer. In this study, we aim to analyze the impact of age on cancer-specific survival (CSS in patients with signet-ring cell carcinoma (SRCC of the colon, a particularly aggressive type of colon cancer. Methods. Information on patients with SRCC of the colon with no distant metastasis was extracted from the US Surveillance, Epidemiology, and End Results (SEER database. An X-tile plot was used to determine the optimal cutoff age at diagnosis. Results. A total of 776 patients were included in data analysis. The X-tile program revealed an optimal cutoff at 35 years of age. A higher percentage of stage III disease and a higher percentage of N2 disease were observed in patients ≤ 35 years of age. The multivariate Cox proportional model demonstrated that patients ≤ 35 years of age were more likely to have a poorer survival outcome compared with patients aged >35 years (HR 1.411, 95% CI 1.032–1.929, and P=0.031. Conclusion. In contrast to the association of younger age with better survival in colon cancer patients, younger age (≤35 years is associated with poorer survival outcome in patients with SRCC of the colon without distant metastasis.

    Background We retrospectively analyzed the incidence and types of postoperative complications after mandibular continuity reconstructions with fibular free flaps (FFF) in patients with oral squamous cell carcinoma (OSCC) and identified potential risk factors for postoperative complications. Methods Data were retrieved from the medical records in the Department of Oral and Maxillofacial Surgery/Oral Pathology, VU University Medical Center/Academic Centre for Dentistry Amsterdam (ACTA), Amsterdam, The Netherlands from April 1995 to September 2013, and were statistically analyzed. Results In this study, 85 patients were included in whom 86 FFFs were used for mandibular reconstruction. Thirty-seven patients (43%) developed ≥ 1 surgical complication and 9 patients (10.5%) developed ≥ 1 systemic complication. Three patients (3.5%) developed total flap failure and six patients (7.0%) developed partial flap failure. Surgical complications were correlated with tobacco use, partial glossectomy, type of mandibular defect, and anatomic staging. Systemic complications were associated with age > 60 years and Charlson comorbidity index > 2. Hospitalization > 30 days was associated with type of mandibular defect. Conclusions The use of the FFF for reconstructing mandibular continuity defects in OSCC patients may be associated with postoperative complications. Patients with coexisting medical conditions and anterior mandibular defects have an increased risk for developing complications. Patients who undergo segmental mandibular resection including a partial glossectomy could have a reduced risk for complications.

    This work aims to estimate the prevalence of Helicobacter pylori ureA gene and evaluate cagA gene-positive strains in both patients of laryngeal squamous cell carcinoma (LSCC) and those with benign laryngeal polyps. This study included 49 patients confirmed pathologically to have LSCC and 15 patients with benign laryngeal polyps over a period from June 2013 to March 2015. Samples of laryngeal tissue were collected during direct laryngoscope under general anesthesia to be pathologically evaluated followed by analysis for H. pylori detection. Each laryngeal tissue sample was divided into three parts; one for bacteriological examination, the second for pathological examination and the third for PCR to detect both ureA and cagA genes. Out of 49 LSCC samples, 31 (64.6 %) was positive for ureA by PCR. Out of them, 29 samples (93.5 %) were cagA positive. Only three cases (20 %) of the benign laryngeal polyp were ureA positive by PCR and one of them was cagA positive by PCR. By the bacteriological culture, only eight samples (25.8 %) gave growth. All of them were ureA positive and only seven of them were cagA positive. There was a significant association between presence of H. pylori and LSCC as compared to benign laryngeal polyp which may contribute in the pathogenesis of laryngeal carcinoma. These results should be confirmed by further studies over larger number of cases.

    Lung large cell neuroendocrine carcinoma (L-LCNEC) is a rare, aggressive, and difficult-to-treat tumor. It is classified as a neuroendocrine subtype of large cell lung carcinoma (LCLC) belonging to the non-small cell lung cancer (NSCLC) group, but it is also included in the neuroendocrine tumor (NET) group. Most of the available data related to its treatment derive from retrospective analyses or small case series. For patients with L-LCNEC, prognosis is generally very poor. In early stages (I-II-III), surgery is recommended but does not seem to be sufficient. Platinum-based adjuvant chemotherapy may be useful while the role of neoadjuvant chemotherapy is still not well defined. In patients with advanced L-LCNEC, the chemotherapy regimens used in SCLC still remain the standard of treatment, but results are not satisfactory. Due to their peculiar clinical and biological features and the lack of literature data, there is an emerging need for a consensus on the best treatment strategy for L-LCNEC and for the identification of new therapeutic options. In this review, we will discuss the key aspects of L-LCNEC management with the aim to clarify the most controversial issues.

  1. Rapid tumor progression in a patient with HPV type 16 associated anal squamous cell carcinoma suffering from long-standing Crohn's disease: A case report

    2016-10-01

    Full Text Available Background and aim: Squamous cell carcinoma (SCC is the most common cancer of the anal region, typically associated with high-risk (hr HPV infection. Furthermore, there is evidence that Crohn's disease predisposes to adenocarcinoma in patients with perianal disease. Materials and methods: A 57-year old patient presenting with long history of Crohn's disease since the age of mid-twenties, went through several surgeries including ileocolectomy and anal fistula resection, combined with immunosuppressive therapy additionally periodically since 2008. One year before death (in 2015 a painful fistula was diagnosed with extensive high grade anal intraepithelial neoplasia (AIN-HG and evidence of invasive growth as non-keratinizing SCC. Tissue samples from several previous and current resection specimens were re-evaluated and extensively investigated for Crohn´s type inflammation, dysplasia and HPV both by immunohistochemistry (p16/Ki67 and molecular subtyping of HPV. Results: AIN-HG and invasive anal squamous cell carcinoma turned out to be strongly positive for p16/Ki67 staining and molecular analysis disclosed a HPV-16 subtype. In contrast, HPV-analysis was negative in all available previous tissue samples including one anal fistula resected five years before (in 2009 which was lined by non-keratinized squamous epithelium without any evidence of dysplasia. Thus, the patient was diagnosed as Crohn's disease with hr-HPV infection that rapidly (< 5ys progressed to AIN-HG and anal SCC. Finally, osseous metastases occurred and the patient died shortly after. Conclusions: This case of a patient diagnosed with SCC of the anal canal in combination with Crohn's disease as well as HPV Type 16 infection, points to the pathomechanism leading to dysplasia and finally cancer. We assume that immunosuppressive therapy in Crohn's disease may predispose to both persistent HPV infection and HPV related invasive anal carcinoma. The accelerated progression of HPV

    Cardiotoxicity is an emerging concern with a new class of drugs known as targeted agents, which include trastuzumab and sunitinib. Sunitinib is a small molecule that inhibits multiple tyrosine kinase receptors. This drug was approved by the United States Food and Drug Administration in 2006 for the treatment of clear cell metastatic renal cell carcinoma and advanced gastrointestinal stromal tumors. We describe a 65-year-old woman who was treated with sunitinib for metastatic clear cell renal cell carcinoma. After 5 months of therapy, she developed acute heart failure requiring hospitalization; sunitinib was immediately discontinued. The patient had classic symptoms of heart failure, including pleural effusion. An echocardiogram revealed a left ventricular ejection fraction of 30%. She received standard treatment for heart failure, including a beta-blocker, an angiotensin-converting enzyme inhibitor, and diuretics. Within 1 month, the patient's symptoms resolved, and subsequent cardiac evaluation showed that her left ventricular ejection fraction returned to normal. According to the Common Terminology Criteria for Adverse Events developed by the National Cancer Institute, her cardiac event associated with sunitinib was defined as grade III toxicity. One month later, sorafenib, another tyrosine kinase inhibitor, was started with the aim of continuing her previous response to sunitinib. After 7 months of sorafenib therapy, the patient had no evidence of heart failure, and her condition was responding to treatment. Clinicians should be aware that sunitinib-induced heart failure occurs occultly and that many--but not all--cases resolve with discontinuation of the drug. Use of sorafenib after sunitinib-induced heart failure appears to be safe and effective, which suggests that cardiotoxicity is not a general class effect of the tyrosine kinase inhibitors.

    Lactate dehydrogenase C is an isoenzyme of lactate dehydrogenase and a member of the cancer-testis antigens family. In this study, we aimed to investigate the expression and functional role of lactate dehydrogenase C and its basic mechanisms in renal cell carcinoma. First, a total of 133 cases of renal cell carcinoma samples were analysed in a tissue microarray, and Kaplan-Meier survival curve analyses were performed to investigate the correlation between lactate dehydrogenase C expression and renal cell carcinoma progression. Lactate dehydrogenase C protein levels and messenger RNA levels were significantly upregulated in renal cell carcinoma tissues, and the patients with positive lactate dehydrogenase C expression had a shorter progression-free survival, indicating the oncogenic role of lactate dehydrogenase C in renal cell carcinoma. In addition, further cytological experiments demonstrated that lactate dehydrogenase C could prompt renal cell carcinoma cells to produce lactate, and increase metastatic and invasive potential of renal cell carcinoma cells. Furthermore, lactate dehydrogenase C could induce the epithelial-mesenchymal transition process and matrix metalloproteinase-9 expression. In summary, these findings showed lactate dehydrogenase C was associated with poor prognosis in renal cell carcinoma and played a pivotal role in the migration and invasion of renal cell carcinoma cells. Lactate dehydrogenase C may act as a novel biomarker for renal cell carcinoma progression and a potential therapeutic target for the treatment of renal cell carcinoma.

    Molecular targeted therapy is a standard treatment for patients with advanced renal cell carcinoma (RCC). Sunitinib is one of the most common molecular-targeted drugs for metastatic RCC. Molecular mechanisms of sunitinib resistance in RCC cells is still ambiguous. The microRNA (miRNA) expression signature of patients with sunitinib failure in RCC was constructed using a polymerase chain reaction (PCR)-based array. Several miRNAs that were aberrantly expressed in RCC tissues from patients treated with sunitinib were identified in this analysis. MicroRNA-101 (miR- 101) was markedly suppressed in sunitinib treated RCC tissues. Restoration of miR-101 significantly inhibited cell migration and invasion in Caki-1 and 786-O cells. Ubiquitin-like with PHD and ring finger domains 1 (UHRF1) was directly suppressed by miR-101 in RCC cells, and overexpression of UHRF1 was confirmed in sunitinib-treated RCC tissues. The pathways of nucleotide excision repair and mismatch repair were significantly suppressed by knockdown of UHRF1. Our findings showed that antitumor miR-101- mediated UHRF1 pathways may be suppressed by sunitinib treatment. PMID:27487138

    Potent helper action is necessary for peptide-based vaccines to efficiently induce antitumor immune responses against advanced cancer. A phase I trial for advanced esophageal squamous cell carcinoma was carried out for patients with HLA-A*2402 using epitope peptides derived from novel cancer-testis antigens, LY6K and TTK, in combination with CpG-7909 (NCT00669292). This study investigated the feasibility and the toxicity as well as induction of tumor antigen-specific immune responses. Nine patients were vaccinated on days 1, 8, 15, and 22 of each 28-day treatment cycle with peptide LY6K-177, peptide TTK-567, and CpG-7909 (level-1; 0, level-2; 0.02, level-3; 0.1 mg/kg) and all were tolerated by this treatment. LY6K-specific T cell responses in PBMCs were detected in two of the three patients in each level. In particular, two patients in level-2/3 showed potent LY6K-specific T cell responses. In contrast, only two patients in level-2/3 showed TTK-567-specific T cell responses. The frequency of LY6K-177 or TTK-567-specific CD8+ T cells increased in patients in level-2/3 (with CpG). The vaccination with peptides and CpG-7909 increased and activated both plasmacytoid dendritic cells and natural killer cells, and increased the serum level of α-interferon. There were no complete response (CR) and partial response (PR), however, one of three patients in level-1, and four of six patients in level-2/3 showed stable disease (SD). In conclusion, vaccination with LY6K-177 and TTK-567 in combination with CpG-7909 successfully elicited antigen-specific CD8+ T cell responses and enhanced the innate immunity of patients with advanced esophageal squamous cell carcinoma. This vaccine protocol is therefore recommended to undergo further phase II trials.

    Trichoepitheliomas (TE) are benign tumours but occasionally can undergo transformation to malignant neoplasms more commonly as Basal Cell Carcinoma (BCC). The correct diagnosis between these tumours is very important because basal cell carcinoma is locally aggressive neoplasm and requires total surgical excision with wide healthy margins while trichoepithelioma needs simple excision. We describe three patients who developed basal cell carcinoma with facial trichoepitheliomas. The only clinical feature that distinguished the carcinomas from the trichoepitheliomas was their larger size, in all three patients, one patient with recurrent, hyper pigmented swelling with surface ulceration and in another patient there are multiple trichoepitheliomas, and other family members are also affected. The history, clinical features and histopathological findings were suggestive of the evolution of basal cell carcinoma directly from trichoepithelioma in our first two cases, but in the third case TE and BCC were separate lesions on face and we are uncertain about whether the BCC developed independently or by transformation from a trichoepithelioma. Based on our clinicopathological observations in the three patients and reports in the recent literature, BCC with follicular differentiation and trichoepithelioma are considered to be highly related.

    Full Text Available Abstract Background Tumours with high proportions of differentiated cells are considered to be of a lower grade to those containing high proportions of undifferentiated cells. This property may be linked to the differentiation properties of stem cell-like populations within malignancies. We aim to identify molecular mechanism associated with the generation of tumours with differing grades from malignant stem cell populations with different differentiation potentials. In this study we assessed microRNA (miRNA regulation in two populations of malignant Embryonal Carcinoma (EC stem cell, which differentiate (NTera2 or remain undifferentiated (2102Ep during tumourigenesis, and compared this to miRNA regulation in ovarian serous carcinoma (OSC patient samples. Methods miRNA expression was assessed in NTera2 and 2102Ep cells in the undifferentiated and differentiated states and compared to that of OSC samples using miRNA qPCR. Results Our analysis reveals a substantial overlap between miRNA regulation in 2102Ep cells and OSC samples in terms of miRNA biosynthesis and expression of mature miRNAs, particularly those of the miR-17/92 family and clustering to chromosomes 14 and 19. In the undifferentiated state 2102Ep cells expressed mature miRNAs at up to 15,000 fold increased levels despite decreased expression of miRNA biosynthesis genes Drosha and Dicer. 2102Ep cells avoid differentiation, which we show is associated with consistent levels of expression of miRNA biosynthesis genes and mature miRNAs while expression of miRNAs clustering to chromosomes 14 and 19 is deemphasised. OSC patient samples displayed decreased expression of miRNA biosynthesis genes, decreased expression of mature miRNAs and prominent clustering to chromosome 14 but not 19. This indicates that miRNA biosynthesis and levels of miRNA expression, particularly from chromosome 14, are tightly regulated both in progenitor cells and in tumour samples. Conclusion miRNA biosynthesis and

    NK cells play a role in many cancer immunotherapies. NK cell activity is tightly regulated by killer immunoglobulin-like receptor (KIR) and KIR-ligand interactions. Inhibitory KIR-ligands have been identified as HLA molecules, while activating KIR-ligands are largely unknown. Individuals that have not inherited the corresponding KIR-ligand for at least one inhibitory KIR gene are termed the "KIR-ligand missing" genotype, and they are thought to have a subset of NK cells that express inhibitory KIRs for which the corresponding KIR-ligand is missing on autologous tissue, and thus will not be inhibited through KIR-ligand recognition. In some settings where an anticancer immunotherapeutic effect is likely mediated by NK cells, individuals with a KIR-ligand missing genotype have shown improved clinical outcome compared to individuals with an "all KIR-ligands present" genotype. In addition, patients receiving hematopoietic stem cell transplants for leukemia may do better if their donor has more activating KIR genes (i.e., KIR haplotype-B). In a recent multi-institution clinical trial of patients with metastatic renal cell carcinoma receiving high-dose IL2 (HD-IL2), 25 % of patients showed a complete or partial tumor response to this therapy. We genotyped KIR and KIR-ligand genes for these patients (n = 107) and tested whether KIR/KIR-ligand genotypes correlated with patient clinical outcomes. In these analyses, we did not find any significant association of KIR/KIR-ligand genotype (either KIR-ligand missing or the presence of KIR haplotype-B) with patient outcome in response to the HD-IL2 therapy.

    The purpose of this study was to retrospectively assess the incidence of bowel wall oedema on computed tomography (CT) in patients with renal cell carcinoma (RCC) treated with sunitinib, and to investigate its association with diarrhoea. We conducted a retrospective analysis of all RCC patients treated with sunitinib at our hospital between December 2005 and December 2011. The presence or absence of bowel wall oedema on these CT examinations was scored. The presence of diarrhoea preceding, during, or after sunitinib treatment was identified from the patient files and retrospectively graded. For 54 of 87 patients, bowel wall oedema was present on at least one CT examination. Of these 54 patients, the right-sided colonic segment was affected in 87 %. Diarrhoea was the most common reported adverse event during treatment, with 58 patients (67 %) having grade 1/2 diarrhoea and 9 patients (10 %) having grade 3. There was a statistically significant correlation between the incidence of CT-scored bowel oedema and diarrhoea during sunitinib treatment (P = 0.004). This study shows a very high incidence of bowel wall oedema and a strong correlation between the incidence of bowel wall oedema and diarrhoea in patients treated with sunitinib. (orig.)

    TP53 mutations have been linked to reduced survival in patients with oral cavity squamous cell carcinoma (OSCC). However, the impact of different types of TP53 mutations remains unclear. Here, we demonstrate that the carriage of missense mutations in the TP53 DNA binding domain (DBD missense mutations) is associated with decreased disease-specific survival (DSS) compared with wild-type TP53 (P=0.002) in a cohort of 345 OSCC patients. In contrast, DSS of patients bearing all of the remaining TP53 mutations did not differ from that observed in wild-type TP53 patients (P=0.955). Our classification method for TP53 mutations was superior to previously reported approaches (disruptive, truncating, Evolutionary Action score, mutations in L2/L3/LSH) for distinguishing between low- and high-risk patients. When analyzed in combination with traditional clinicopathological factors, TP53 DBD missense mutations were an independent prognostic factor for shorter DSS (P=0.014) alongside with advanced AJCC T- and N-classifications and the presence of extracapsular spread. A scoring system that included the four independent prognostic factors allowed a reliable patient stratification into distinct risk groups (high-risk patients, 16.2%). Our results demonstrate the usefulness of TP53 DBD missense mutations combined with clinicopathological factors for improving the prognostic stratification of OSCC patients.

  11. Management for Patients with De Novo or Recurrent Tumors in the Residual Kidney after Surgery for Nonfamilial Bilateral Renal Cell Carcinoma

    Full Text Available The tumor de novo in the residual kidney after surgery for nonfamilial bilateral renal cell carcinoma (RCC is problematic. We reviewed 5 patients who experienced such a situation. Three patients had had metachronous bilateral RCC, treated with radical nephrectomy in one kidney and nephron-sparing surgery (NSS in the other. Two patients had had synchronous disease; one patient had received radical nephrectomy and NSS, and the other bilateral NSS. The 5 patients had another solid mass/de novo tumor in the residual kidney 16–88 (mean 46.8 months after surgery. For the tumor de novo in earlier years (1992–1999, one patient underwent surgery and hemodialysis, and the other selected a conservative observation. In recent years (2000–2007, one patient was conservatively observed; the remaining 2 received computerized-tomography-guided radiofrequency ablation, and the local tumors were well controlled postoperatively for 20 and 12 months with their renal function unimpaired. Ablative techniques can potentially strike a balance between oncological and nephrological outcomes in patients with sporadic multiple RCC, successful management of which was difficult previously.

    This study examined the biological and clinical significance of NAC1 (nucleus accumbens associated 1) expression in both cervical squamous cell carcinomas and adenocarcinomas/adenosquamous carcinomas. Using immunohistochemistry, the frequency of positive NAC1 expression in adenocarcinomas/adenosquamous carcinomas (31.0%; 18/58) was significantly higher than that in squamous cell carcinomas (16.2%; 12/74) (P = .043). NAC1 gene amplification was identified by fluorescence in situ hybridization in 5 (7.2%) of 69 squamous cell carcinomas. NAC1 amplification was not identified in the adenocarcinomas (0%; 0/58). Positive NAC1 expression was significantly correlated with shorter overall survival in squamous cell carcinomas (P NAC1 expression in squamous cell carcinomas was an independent prognostic factor for overall survival after standard radiotherapy (P = .0003). In contrast to squamous cell carcinomas, positive NAC1 expression did not correlate with shorter overall survival in adenocarcinomas/adenosquamous carcinomas (P = .317). Profound growth inhibition, increased apoptosis, decreased cell proliferation, and decreased cell migration and invasion were observed in silencing RNA-treated cancer cells with NAC1 overexpression compared with cancer cells without NAC1 expression. NAC1 overexpression stimulated proliferation, migration, and invasion in the cervical cancer cell lines TCS and Hela P3, which normally lack NAC1 expression. These findings indicate that NAC1 overexpression is critical to the growth and survival of cervical carcinomas irrespective of histologic type. Furthermore, they suggest that NAC1 silencing RNA-induced phenotypes depend on the expression status of the targeted cell line. Therefore, cervical carcinoma patients with NAC1 expression may benefit from a targeted therapy irrespective of histologic type.

    Small cell carcinoma of the uterine cervix accounts for 1-3% of all cervix cancers. It is an aggressive disease with a poor prognosis. To date, no effective treatment protocol has been determined. Surgery, radiotherapy, and chemotherapy have been used either alone or in combination. Recent data suggests that survival in patients with early staged small cell carcinoma of the cervix is better with surgery combined with chemo-radiotherapy. Here, we presented two patients with stage IB1 small cell carcinoma of the uterine cervix. For both patients, definitive surgery was performed with pelvic and para-aortic lymphadenectomy. Subsequently, they were treated with pelvic external radiotherapy and high-dose-rate intracavitary brachytherapy with concurrent cisplatin based chemotherapy. They were alive with no evidence of disease at 91 and 65 months, respectively.

    Full Text Available Abstract Background Cancer stem cell model suggested that tumor progression is driven by the overpopulation of cancer stem cells and eradicating or inhibiting the symmetric division of cancer stem cells would become the most important therapeutic strategy. However, clinical evidence for this hypothesis is still scarce. To evaluate the overpopulation hypothesis of cancer stem cells the association of percentage of CD133+ tumor cells with clinicopathological parameters in colon cancer was investigated since CD133 is a putative cancer stem cell marker shared by multiple solid tumors. Patients and methods Tumor tissues matched with adjacent normal tissues were collected from 104 stage IIIB colon cancer patients who were subject to radical resection between January, 1999 to July, 2003 in this center. The CD133 expression was examined with immunohistochemical staining. The correlation of the percentage of CD133+ cell with clinicopathological parameters and patients' 5-year survival was analyzed. Results The CD133+ cells were infrequent and heterogeneous distribution in the cancer tissue. Staining of CD133 was localized not only on the glandular-luminal surface of cancer cells but also on the invasive budding and the poorly differentiated tumors with ductal structures. Both univariate and multivariate survival analysis revealed that the percentage of CD133+ cancer cells and the invasive depth of tumor were independently prognostic. The patients with a lower percentage of CD133+ cancer cells (less than 5% were strongly associated with a higher 5-year survival rate than those with a higher percentage of CD133+ cancer cells (greater than or equal to 55%. Additionally, no correlation was obtained between the percentage of CD133+ cancer cells and the other clinicopathological parameters including gender, age, site of primary mass, pathologic types, grades, and invasive depth. Conclusion The fact that a higher percentage CD133+ cells were strongly associated

    Full Text Available Oral squamous cell carcinoma accounts for 90% to 95% of all oral malignancies. Though its diagnosis seldom presents difficulty, it is the cancer staging and histopathological grading that are important to prognostication; and micronuclei are good prognostic indicators. Micronucleus frequencies in oral exfoliated cells stained with papanicolaou stain were counted and correlated with the histopathological grades and clinical stages of squamous cell carcinoma patients. They were also compared with healthy control subjects. Micronuclei (MN frequencies were found higher in squamous cell carcinoma patients than in control subjects. MN frequencies were also found to be raised with increasing histological grades of squamous cell carcinoma.

    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

    Full Text Available Aim. Data from The Cancer Genome Atlas (TCGA show that the ZNF703 gene amplifies and overexpresses in head and neck squamous cell carcinomas (HNSCC. However, the clinical relevance of this observation in HNSCC is unclear. The purpose of this study was to clarify the expression of ZNF703 protein and its prognostic effect on HNSCC. Methods. Two hundred ten HNSCC patients from Sun Yat-Sen University Cancer Center with complete survival follow-up were included in this study. Tumor samples from primary sites were collected. The expression of the ZNF703 protein was tested by immunohistochemistry (IHC. Results. The high expression of ZNF703 in HNSCC tumor tissues was significantly higher than that of the matched noncancerous tissues (48.6% versus 11.6%, P<0.001. ZNF703 overexpression was correlated with tumor position (laryngeal carcinoma and recurrence (all P<0.05. Multivariate analysis revealed that ZNF703 protein overexpression was an independent prognostic factor (P=0.022, hazard ratio = 1.635, 95% CI 1.073–2.493 in HNSCC patients. Conclusion. ZNF703 overexpression is associated with adverse prognosis in HNSCC, which might be a novel biomarker of HNSCC.

    Full Text Available This study investigated the presence of human papillomavirus (HPV DNA and viral types in 33 cases of oral squamous cells carcinoma (OSCC and compared the immunohistochemical expression of the cell-cycle markers p21 and pRb between cases of the disease with and without HPV. DNA was extracted from paraffin-embedded tissue and amplified by PCR for the detection of HPV DNA. Viral typing was performed by dot blot hybridization. Immunohistochemistry was performed by the streptavidinbiotin technique. HPV DNA was detected in 11 (33.33% of the 33 cases. The prevalent viral type was HPV 18 (81.81%. A significant association was observed between the presence of HPV and immunohistochemical expression of pRb, but not between p21 expression and the presence of the virus. The low frequency of detection of HPV DNA in OSCC suggests a possible participation of the virus in the development and progression of only a subgroup of these tumors.

    Purpose We evaluated the efficacy and toxicity of mammalian target rapamycin inhibitors in Korean patients with metastatic renal cell carcinoma (mRCC) with chronic renal insufficiency not requiring dialysis. Materials and Methods Korean patients with mRCC and chronic renal insufficiency not requiring dialysis treated with everolimus or temsirolimus between January 2008 and December 2014 were included. Patient characteristics, clinical outcomes, and toxicities were evaluated. Overall survival (OS) and progression-free survival (PFS) durations were evaluated according to the degree of renal impairment. Results Eighteen patients were considered eligible for the study (median age, 59 years). The median glomerular filtration rate was 51.5 mL/min/1.73 m2. The best response was partial response in six patients and stable disease in 11 patients. The median PFS and OS durations were 8 months (95% confidence interval [CI], 0 to 20.4) and 32 months (95% CI, 27.5 to 36.5), respectively. The most common non-hematologic and grade 3/4 adverse events included stomatitis, fatigue, flu-like symptoms, and anorexia as well as elevated creatinine level. Conclusion Mammalian target rapamycin inhibitors were efficacious and did not increase toxicity in Korean patients with mRCC and chronic renal insufficiency not requiring dialysis. PMID:26875195

    Full Text Available The prognostic value of the Fuhrman renal-cell carcinoma (RCC gradation system has been supported by numerous studies. The high RCC  grade after Fuhrman is a sign of the high risk of recurrence even in patients with the early stages of the disease, in clear-cell tumor in par-  ticular. The anticancer vaccine Oncophage is recommended to prevent a recurrence and/or to increase a relapse-free period in patients with  early stages of RCC. While using this vaccine, one should follow the Fuhrman histological gradation system and use a coordinated multi-  disciplinary approach to treating this group of patients. This paper describes the Fuhrman histological gradation system, indications for the  use of Oncophage in patients with the early stages of ECC and a moderate risk of a recurrence. The role of urological surgeons, oncologists,  and pathomorphologists in the treatment of patients with early stages of ECC is also considered.

    Protein Tyrosine Phosphatase Receptor J (PTPRJ) has been reported to be a tumor suppressor in various human cancers. The aim of this study was to investigate the clinical significance of PTPRJ in ESCC patients and its effects on biological behaviors of ESCC cells. PTPRJ expression, at mRNA and protein levels, were respectively detected by quantitative real-time PCR, western blot and immunohistochemistry, based on 106 newly diagnosed ESCC patients. The associations between PTPRJ expression and clinicopathological characteristics of ESCC patients were statistically analyzed. Then, the effects of PTPRJ in migration and invasion were determined by wound healing and transwell assays based on ESCC cell line transfected with siRNA or expression vector of PTPRJ. Expression of PTPRJ at mRNA and protein levels were both significantly lower in ESCC tissues than those in normal esophageal mucosa. Immunohistochemistry showed that PTPRJ protein was localized in the cytoplasm of cancer cells in ESCC tissues. In addition, PTPRJ downregulation was found to be closely correlated with advanced tumor stage (P = 0.01) and poor differentiation (P = 0.03). Moreover, knockdown of PTPRJ in KYSE510 cells could significantly promote cell migration and invasion (both P ESCC patients. PTPRJ may function as a tumor suppressor and play an important role in the regulation of ESCC cell motility, suggesting its potentials as a therapeutic agent for human ESCC.

    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.

    John C Morris

    Full Text Available BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

    Full Text Available Renal cell carcinoma (RCC is the most common type of kidney cancer in adults. Nephron sparing resection (partial nephrectomy has been the “gold standard” for the treatment of resectable disease. With the widespread use of cross sectional imaging techniques, more cases of renal cell cancers are detected at an early stage, i.e. stage 1A or 1B.  This has provided an impetus for expanding the nephron sparing options and especially, percutaneous ablative techniques.  Percutaneous ablation for RCC is now performed as a standard therapeutic nephron-sparing option in patients who are poor candidates for resection or when there is a need to preserve renal function due to comorbid conditions, multiple renal cell carcinomas, and/or heritable renal cancer syndromes. During the last few years, percutaneous cryoablation has been gaining acceptance as a curative treatment option for small renal cancers. Clinical studies to date indicate that cryoablation is a safe and effective therapeutic method with acceptable short and long term outcomes and with a low risk, in the appropriate setting.  In addition it seems to offer some advantages over radio frequency ablation (RFA and other thermal ablation techniques for renal masses.

    Hypothyroidism in patients with metastatic renal cell carcinoma (mRCC) during treatment with the tyrosine kinase inhibitors (TKIs) sunitinib and sorafenib is a well-established side effect. Furthermore, the potential role of hypothyroidism as predictive marker of outcome has been studied but with conflicting results. The aim of the present meta-analysis was to assess the predictive value of hypothyroidism for progression-free (PFS) and overall survival (OS) in patients with mRCC during TKI therapy. We searched PubMed and the electronic abstract databases of the major international congresses' proceedings to identify all eligible studies that reported a correlation between the development of hypothyroidism during TKI treatment and outcome in patients with mRCC. Hazard ratios (HRs) with 95% confidence intervals (CIs) for PFS and OS were obtained from these publications and pooled in a meta-analysis. Eleven studies with a total of 500 patients fulfilled the inclusion criteria. We found no statistical significant difference in PFS between patients who developed hypothyroidism during sunitinib therapy and unaffected patients (HR, 0.82; 95% CI, 0.59-1.13; P = .22; 6 studies; 250 patients). The HR for OS was 0.52 (95% CI, 0.31-0.87; P = .01) for patients who developed hypothyroidism during sunitinib therapy compared with patients who did not (4 studies; 147 patients). The development of hypothyroidism during TKI therapy is not clearly shown to be predictive of efficacy in patients with mRCC. The observed advantage in OS for the patients with acquired hypothyroidism should be interpreted with caution.

    It has been suggested that FDG PET has predictive value for the prognosis of treated oesophageal carcinoma. However, the studies reported in the literature have shown discordant results. The aim of this study was to determine whether pretherapy quantitative metabolic parameters correlate with patient outcomes. Included in the study were 67 patients with a histological diagnosis of oesophageal squamous cell carcinoma. Each patient underwent {sup 18}F-FDG PET (4.5 MBq/kg) before chemoradiotherapy. Quantitative analysis was performed using the following parameters: age, weight loss, location, N stage, OMS performance status, MTV{sub p} and MTV{sub p'} (metabolic tumour volume determined by two different physicians), MTV{sub 40%} (volume for a threshold of 40 % of SUVmax), MTV{sub a} (volume automatically determined with a contrast-based adaptive threshold method), SUVmax, SUVmean and TLG (total lesion glycolysis). MTV{sub p} and MTV{sub 40%} were highly correlated (Pearson's index 0.92). SUVmean{sub p} and SUVmean{sub 40%} were also correlated (Pearson's index 0.86), as were TLG{sub p} and TLG{sub 40%} (Pearson's index 0.98). Similarly, the parameters obtained with the adaptive threshold method (MTV{sub a}, SUVmean{sub a} and TLG{sub a}) were correlated with those obtained manually (MTV{sub p}, SUVmean{sub p} and TLG{sub p}). The manual metabolic tumour volume determination (MTV{sub p} and MTV{sub p'}) was reproducible. Multivariate analysis for disease-free survival (DFS) showed that a larger MTV{sub p} was associated wit
