    Full Text Available A 77-year-old female, who suffered from rheumatoid arthritis and hypothyroidism, developed severe muscle weakness. Clinical features, blood results and muscle biopsy suggested a possible diagnosis of dermatomyositis. A computed tomography of the chest, abdomen and pelvis showed a solid mass in the left kidney. She underwent a left laparoscopic nephrectomy and histology confirmed conventional (clear cell renal cell carcinoma. She recovered slowly and almost back to normal life after 6 months. Early appreciation of the typical skin rash may provide a clue to the diagnosis and screening for neoplasm may improve prognosis.

    To investigate the therapeutic effect of dendritic cells pulsed with lysates of heat-treated CT26 colon carcinoma cells. Bone marrow-derived DCs were pulsed with lysates of heat-treated tumor cells and were used to immunize BALB/c mice with established colon carcinoma. Cytotoxic T lymphocyte (CTL) response was detected. The therapeutic effect induced by DCs was observed by tumor weight and survival time. DCs pulsed with lysates of heat-treated tumor cells markedly induced specific cytotoxic activity of CTLs. Tumor growth in the immunized BALB/c mice was significantly inhibited and the survival time of the tumor-bearing mice was prolonged, DCs pulsed with lysates of heat-treated tumor cells have an observable therapeutic effect on established colon carcinoma-bearing mice.

    Background Papillomatosis presents, most frequently, as multiple lesions of the respiratory tract, which are usually considered benign. Malignant degeneration into squamous cell carcinoma is quite common, although curative approaches vary a lot in modern literature. Case report We report a case of a 66-year-old male patient with the coexistence of multiple squamous cell papilloma and carcinoma in the upper trachea with severe airway obstruction that was diagnosed through bronchoscopy and treated by performing an urgent tracheostomy, followed by concurrent chemotherapy and radiotherapy. There was no evidence of recurrence after a 12-month follow-up period. Conclusion This study underlines the diagnostic and therapeutic value of bronchoscopy as well as multimodality palliative treatment in such cases. To the best of our knowledge, this is the first study to describe an immediate treatment protocol with tracheostomy and concurrent chemotherapy/radiotherapy in a patient with squamous cell tracheal papilloma and carcinoma.

    Renal cell carcinoma is a rare pediatric malignant tumor of the kidney. Unlike Wilms tumor, the efficacy of chemotherapy and radiation therapy in pediatric renal cell carcinoma remains uncertain. Surgery is the best treatment and prognosis is favorable when the tumor is localized and completely eradicated. We report an exceptional observation in a 7-year-old girl with renal cell carcinoma who had been treated 20 months previously for Ewing sarcoma with chemotherapy and radiotherapy. The renal tumor was revealed by abdominal pain without hematuria. She underwent a radical nephrectomy, and histopathology concluded in renal carcinoma associated with translocation Xp 11.2 grade 3 of Furhrman pT3a N1. No adjuvant therapy was given. After 3 years of follow-up, there is no evidence of local or metastatic recurrence. This observation is significant given the very young age of this patient, the occurrence after Ewing sarcoma with a short disease-free interval. It seems that translocation renal cell carcinoma is associated with previous exposure to chemotherapy, particularly topoisomerase II inhibitors or alkylating agents. PMID:26702489

    High grade neuroendocrine carcinomas (HGNEC) treated by cystectomy often carry an original diagnosis of typical urothelial carcinoma (UC). The correct diagnosis of HGNEC is critical in influencing the decision for early chemotherapy, potentially followed by cystectomy. The objective of this study was to characterise the features of HGNEC treated by radical cystectomy. The study consisted of 79 patients with HGNEC including small cell (68 patients), large cell neuroendocrine (LCNEC) (5 patients) and mixed neuroendocrine (mixed-NEC) carcinoma (6 patients) matched with 122 patients with UC, treated at our institution between 1987 and 2014. Morphometric analysis for cell and nuclear size as well as immunophenotyping for neuroendocrine markers and cell-cycle regulators were applied to tissue microarrays. Small cell, LCNEC and mixed-NEC are a morphological spectrum of high grade neuroendocrine carcinoma with overlapping histological features, identical immunophenotype, Ki-67 proliferative rate and patient outcomes. Finally, the nuclear size criteria is misleading as HGNEC, particularly cases of LCNEC and mixed-NEC, may have enlarged nuclei compared to small cell carcinomas and are more prone to be misdiagnosed as UC, thereby preventing appropriate management.

    Background Treatment of primary renal cell carcinoma using radiotherapy with curative intent is rare, because renal cell carcinoma is generally regarded as a radiation-resistant tumor. Recently, stereotactic body radiation therapy has been radically applied for cancers in various organs including renal cell carcinoma. However, there were few reports describing pathological changes of renal cell carcinoma post stereotactic body radiation therapy. This is the first report we are aware of docume...

  11. Risk stratification of patients with advanced squamous cell carcinoma of cervix treated by radiotherapy alone

    International Nuclear Information System (INIS)

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

    Full Text Available Basal cell carcinoma (BCC is the most common skin cancer worldwide. Surgical excision is considered to be the primary therapeutic modality wherever possible. For inoperable cases, 5% imiquimod seems to be a good alternative. We present two cases of nodular pigmented BCCs on the face in elderly women successfully treated with 5% imiquimod cream application resulting in complete clinical clearance of lesion as well as on histology and dermatoscopy. There was no recurrence of the lesion on 2 years follow-up for the first and 1.5 years for the second patient.

    Xeroderma pigmentosum (XP) is an autosomal recessive disease characterized by solar sensitivity, photophobia, early onset of freckling, and solar-induced cutaneous neoplastic changes. Management of patients with XP is a therapeutic challenge as they usually develop multiple cutaneous malignancies, making surgical therapy difficult, and continue to form skin malignancies at a high rate. We describe a 30-year-old Chinese man with XP who had been previously treated with excision and dermatoplasty. Upon recurrence of multiple superficial, ulcerative, and pigmented lesions, imiquimod 5% cream was recommended for 4 months. His multiple facial lesions demonstrated an excellent response to topical imiquimod 5% cream with minor side effects. This favorable response indicates that topical application of imiquimod 5% cream is an effective means of treating multiple basal cell carcinomas in XP. PMID:25754701

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

  20. Prognosis of esophageal squamous cell carcinoma treated by endoscopic submucosal dissection

    International Nuclear Information System (INIS)

    One hundred and fifty eight patients who had esophageal squamous cell carcinoma (SCC) were treated by endoscopic submucosal dissection (ESD) from Jan. 2,000 to Dec. 2006. The invasion depth was divided as epithelium (EP), Lamina propria mucosa (LPM), muscularis mucosa (MM) and submuosal layer. When the depth of submucosal invasion was 200 micrometers or less, the invasion depth was defined as SM1. In this study, out of 158 patients 28 patients had MM SCC, and 12 patients had SM1 SCC. The additional therapies such as Esophagectomy or Chemo Radio Therapy (CRT) were recommended to the patients, when lymphatic permeation was found. Among the patients who had MM SCC, 5 patients had lymphatic permeation. Among the patients who had SM1 SCC, 4 patients had lymphatic permeation. 2 MM and 2 SM1 patients were treated by CRT and the other 5 patients who had lymphatic permeation refused the additional therapy because of other diseases. All 4 patients who were treated by CRT are alive, but lymph node metastasis was found in 2 of the patients who refused CRT. One died of esophageal SCC, and one died of another disease. No lymph node metastasis was found in 23 patients who had MM without lymphatic permeation, and 8 patients who had SM1 without lymphatic permeation. According to our data, the indication of esophageal ESD could be expanded for MM or SM1 SCC without lymphatic permeation. (author)

    Full Text Available Abstract Background Conventional cancer therapy including surgery, radiation, and chemotherapy often are physically debilitating and largely ineffective in previously treated patients with recurrent head and neck squamous cell carcinoma (SCC. A natural photochemical, hypericin, could be a less invasive method for laser photodynamic therapy (PDT of these recurrent head and neck malignancies. Hypericin has powerful photo-oxidizing ability, tumor localization properties, and fluorescent imaging capabilities as well as minimal dark toxicity. The current study defined hypericin PDT in vitro with human SCC cells before the cells were grown as tumor transplants in nude mice and tested as a model for hypericin induced tumor fluorescence and PDT via laser fiberoptics. Methods SNU squamous carcinoma cells were grown in tissue culture, detached from monolayers with trypsin, and incubated with 0.1 μg to 10 μg/ml of hypericin before exposure to laser light at 514, 550, or 593 nm to define optimal dose, time, and wavelength for PDT of tumor cells. The SCC cells also were injected subcutaneously in nude mice and grown for 6–8 weeks to form tumors before hypericin injection and insertion of fiberoptics from a KTP532 surgical laser to assess the feasibility of this operating room instrument in stimulating fluorescence and PDT of tumors. Results In vitro testing revealed a hypericin dose of 0.2–0.5 μg/ml was needed for PDT of the SCC cells with an optimal tumoricidal response seen at the 593 nm light absorption maximum. In vivo tumor retention of injected hypericin was seen for 7 to10 days using KTP532 laser induced fluorescence and biweekly PDT via laser fiberoptics led to regression of SCC tumor transplants under 0.4 cm2 diameter, but resulted in progression of larger size tumors in the nude mice. Conclusion In this preclinical study, hypericin was tested for 514–593 nm dye laser PDT of human SCC cells in vitro and for KTP532 surgical laser targeting

  4. Prognostic factors in invasive squamous cell carcinoma of the vulva treated with surgery and irradiation

    International Nuclear Information System (INIS)

    From 1958 through 1980, 113 women with invasive squamous cell carcinoma of the vulva were treated with vulvectomy. Postoperative irradiation was given with cobalt-60 beam or 10 MV photons from a linear accelerator from anterior fields including the vulva and groins, with the intention of delivering 40-52 Gy with 2-4 Gy/day at a depth of 0.5 cm or 2 cm. The overall corrected five-year survival rate was 68%. The prognosis was shown to worsen significantly with advancing stages (I/96%, II/75%, III/62% and IV/19%), increasing grades (G1/78%, G2/70% and G3/22%) and increasing size of the tumor (T1/90%, T2/71% and T3/37%), as it also did when there were signs of vascular invasion, multifocal tumors or positive nodes in the inguinal regions. Recurrences were diagnoses in 32% of the patients. With the less aggressive surgical approach used, combined with radiation therapy to eradicate subclinical disease, the morbidity rate was acceptable and the survival rate comparable to that reported after more aggressive surgery.

    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 immunosuppressant azathioprine is used to prevent graft rejection after organ transplantation. To investigate whether azathioprine-associated mutagenesis contributes to the high incidence of skin tumours in organ transplant recipients (OTRs), we analysed PTCH gene mutations in 60 basal cell carcinomas (BCC); 39 from OTRs receiving azathioprine and 21 from individuals never exposed to azathioprine. PTCH was mutated in 55% of all tumours, independent of azathioprine treatment. In both the a...

  13. FADD Expression as a Prognosticator in Early-Stage Glottic Squamous Cell Carcinoma of the Larynx Treated Primarily With Radiotherapy

    International Nuclear Information System (INIS)

    Purpose: We recently reported on the identification of the Fas-associated death domain (FADD) as a possible driver of the chromosome 11q13 amplicon and the association between increased FADD expression and disease-specific survival in advanced-stage laryngeal carcinoma. The aim of this study was to examine whether expression of FADD and its Ser194-phosphorylated isoform (pFADD) predicts local control in patients with early-stage glottic carcinoma primarily treated with radiotherapy only. Methods and Materials: Immunohistochemical staining for FADD and pFADD was performed on pretreatment biopsy specimens of 92 patients with T1–T2 glottic squamous cell carcinoma primarily treated with radiotherapy between 1996 and 2005. Cox regression analysis was used to correlate expression levels with local control. Results: High levels of pFADD were associated with significantly better local control (hazard ratio, 2.40; 95% confidence interval, 1.04–5.55; p = 0.040). FADD overexpression showed a trend toward better local control (hazard ratio, 3.656; 95% confidence interval, 0.853–15.663; p = 0.081). Multivariate Cox regression analysis showed that high pFADD expression was the best predictor of local control after radiotherapy. Conclusions: This study showed that expression of phosphorylated FADD is a new prognostic biomarker for better local control after radiotherapy in patients with early-stage glottic carcinomas.

  14. Squamous cell carcinoma of the floor of the mouth treated by radiotherapy

    International Nuclear Information System (INIS)

    Retrospective analysis was made of 110 cases of squamous cell carcinoma of the floor of the mouth. Age of the cases ranged from 34 to 86, with the mean value of 59.9 years. There was high sex preponderance to male(male: 93, female:17). Habitual heavy intake of alcohol and tobacco was also detected. Five- and 10-year survival rates according to Stages were; Stage I: 69%, 38%, Stage II: 40%, 20%, Stages III-IV: 33%, 15%, respectively. Local control rates by radiotherapy were; T1:80%, T2:56%, T3:17%. Small lesion tends to be localized to the floor of the mouth and was successfully controlled by implant without complication. As the size of the tumor increases, lesion tends to infiltrate into the ventral side of the mobile tongue, alveolar ridge of mandible as well as muscle of the floor and mandibular body. External radiotherapy of 3,000 cGy/3 weeks with concomitant i.v. injection of 90 mg of Bleomycin yielded remarkable reduction of mass size in most cases with T2, and complete disappearance of the tumor after sufficient period of follow-up in 21% of the cases treated. Among the complications attributable to radiotherapy, osteoradionecrosis was most common and serious and appeared in 13 out of 29 cases withou local recurrence after radiotherapy. Incidence of complications was higher in cases with linear-arrayed sources than with seed sources, higher in combined external and interstitial radiotherapy than in interstitial alone, and was higher in the dentulous cases than in the edentulous. Cases with positive nodes on first referral were 44(40%), of which 12 cases were later proved to be false during the clinical course. Fifteen N0 cases developed neck nodes during or after the treatment to the primary site which necessitated surgery. Prognosis was related to the surgical results of the neck. Homo- and contralateral submandibular, homolateral upper jugular, homolateral middle jugular nodes were the common sites involved. (author)

    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.

  2. Development of coronary artery stenosis in a patient with metastatic renal cell carcinoma treated with sorafenib

    International Nuclear Information System (INIS)

    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. 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. 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

  4. Locally-regionally advanced tonsillar squamous cell carcinoma treated with concurrent chemoradiotherapy

    International Nuclear Information System (INIS)

    Purpose: To perform a retrospective review of stage III-IV squamous cell carcinoma of the tonsil managed by definitive concurrent chemoradiotherapy (CCRT) in order to analyze the patients’ outcome and to evaluate the acute and late toxic effects of this treatment modality. Material and methods: Between January 2005 and December 2010, 36 patients with locally and/or regionally advanced tonsillar cancer underwent three dimensional conformal radiotherapy (3DCRT) with concurrent platinum-based chemotherapy. The dose prescription of the planning target volume for gross tumor and low-risk subclinical disease was 70 Gy and 50 Gy, respectively. Conventional fractionation with a daily dose of 2.0 Gy, 5 times per week was used. Concurrent chemotherapy consisted of cisplatin 30 mg/m2 given on a weekly basis. Acute and late radiotherapy-related toxicities were recorded using European Organization for Research and Treatment of Cancer/Radiation Therapy Oncology Group (EORTC/RTOG) grading system. The 3-year locoregional relapse-free survival (LRRFS), disease-free survival (DFS), and overall survival (OS) rates were calculated using the Kaplan-Meier method. Results: The median follow-up of all patients was 20.5 months (range, 5 to 90 months). The median followup of living patients was 59 months (range, 30 to 90 months). Complete response rates of the primary tumor and of the nodal disease were 72.2% and 64.0%, respectively. A complete composite response was present in 25 patients (69.4%). Treatment failure occurred in 15 out of 25 patients who achieved complete composite response following CCRT. The 3-year LRRFS, DFS, and OS rate was 38.8%, 27.8%, and 27.3%, respectively. Grade 3 mucositis occurred in 58.3% of patients. Xerostomia grade 2 was revealed in 72.2% of patients. Conclusion: Taking into account the low 3-year survival rates observed in our study and the high percentage of grade 2 xerostomia, it can be concluded that in the future, instead of 3DCRT with concurrent

    Full Text Available Abstract Background Liver transplantation is the most effective therapy for cirrhosis-associated hepatocellular carcinoma (HCC but its utility is limited by post-transplant tumor recurrence. Use of the Milan, size-based criteria, has reduced recurrence rate to less than 10% but many patients remain ineligible. Reduction of tumor size with local therapies has been used to “downstage” patients to allow them to qualify for transplantation, but the optimal criteria to predict tumor recurrence in these latter patients has not been established. The existence of a progenitor cell population, sometimes called cancer stem cells (CSCs, has been proposed to be one mechanism accounting for the chemotherapy resistance and recurrence of hepatocellular carcinoma. The aim of this study was to determine if transcatheter arterial chemoemolization (TACE treated tumors have increased CSC marker expression and whether these markers could be used to predict tumor recurrence. Methods Formalin fixed specimens were obtained from 39 HCC liver explants (23 with no treatment and 16 after TACE. Immunohistochemical staining was performed for EpCAM, CD44, CD90, and CD133. Staining for each marker was scored 0–3 by evaluating the number and intensity of positive tumor cells in 5 hpf of tumor in each specimen. Results TACE treated tumors displayed greater necrosis and fibrosis than non-TACE treated samples but there were no differences in morphology between the viable tumor cells of both groups. In TACE treated specimens, the staining of both EpCAM and CD133 was greater than in non-TACE specimens but CD44 and CD90 were the same. In the TACE group, the presence of high EpCAM staining was associated with tumor recurrence. Four of ten EpCAM high patients recurred while 0 of 6 EpCAM low patients recurred (P = 0.040. None of the other markers predicted recurrence. Conclusion High pre-transplant EpCAM staining predicted HCC recurrence. This suggests that the abundance of

  15. Oropharyngeal squamous cell carcinoma with known human papillomavirus status treated with definitive chemoradiotherapy: patterns of failure and toxicity outcomes

    International Nuclear Information System (INIS)

    Tumor human papillomavirus (HPV) status has emerged as one of the most powerful prognostic factors for disease control and survival in patients with oropharyngeal squamous cell carcinoma (OPSCC). We reviewed our experience in patients with OPSCC and known tumor HPV status treated with definitive chemoradiotherapy (CRT). Patients with stage III-IVb OPSCC and known tumor HPV status treated with CRT between 2006 and 2011 were identified from an IRB approved registry for this retrospective review. Outcomes were estimated using the Kaplan-Meier method and compared between HPV-positive and negative patients using the log-rank test. Of the 121 pts (89% male, 93% Caucasian) included in this study, median age was 57 (range: 40–73) and median follow-up was 21 months (range: 6–63). Ninety-seven (80%) patients were HPV-positive and 24 (20%) were HPV-negative. Primary site was base of tongue (55%), tonsil (44%), and oropharyngeal wall (2%). Two year rates of locoregional recurrence (3% vs. 26%; p = 0.002), disease free survival (93% vs. 64%; p = 0.001) and overall survival (94% vs 73%; p = 0.002) were superior in HPV-positive patients, while rates of distant recurrence were similar (3% vs. 5%; p = 0.98). While acute toxicities were similar between both groups, patients with HPV-positive disease were more likely to resume a normal diet (90% vs. 65%; p = 0.017) at last follow up. Also, no HPV-positive patient required a feeding tube beyond 6 months after treatment, compared with 24% of HPV-negative patients. Definitive CRT produces excellent rates of disease control with minimal late toxicity for patients with HPV-positive OPSCC.

    BACKGROUND: It is unknown whether lymph node metastases (LNM) and their localization negatively affect clinical outcome in metastatic renal cell carcinoma (mRCC) patients. OBJECTIVE: To evaluate the clinicopathological features, survival outcome, and treatment response in mRCC patients with LNM...... supradiaphragmatic (SPD) LNM, subdiaphragmatic (SBD) LNM, and patients with LNM in both locations (SPD+/SBD+) without histologic considerations, and then separately in clear cell RCC (ccRCC) and non-clear cell RCC (nccRCC) patients, respectively. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was...... with shorter survival outcome when metastatic renal cell carcinoma (mRCC) patients are treated with targeted therapies. Clinical trials should evaluate whether surgical removal of regional lymph nodes at the time of nephrectomy may improve outcomes in high-risk RCC patients....

  17. Follow-up neurological evaluation in patients with small cell lung carcinoma treated with prophylactic cranial irradiation and chemotherapy

    International Nuclear Information System (INIS)

    The safety of prophylactic cranial irradiation (PCI) has recently been questioned, based on reports of computerized tomographic abnormalities mainly seen in children, who received PCI and chemotherapy, primarily for acute lymphocytic leukemia. In order to clarify the significance of these findings, we examined a series of adult patients who were long term survivors (18 to 48 months, median 26 months, after all treatment). These patients were treated with combination radiotherapy and chemotherapy for small cell lung carcinoma and received cranial irradiation in the absence of known brain involvement by tumor. Patients were divided into three groups: three patients who received PCI + intrathecal methotrexate (MTX) (Group 1), and ten who received only PCI (Group 2). An additional three patients (Group 3) were identified as long term survivors (41 to 70 months after all treatments) of a similar treatment program without any central nervous system (CNS) prophylaxis. All patients received an extensive evaluation of a variety of clinical parameters, EEG, and computer tomography (CT). Although CT abnormalities were detectable (mild cerebral atrophy in eight patients, encephalomalacia in one of the 13 patients with CNS prophylaxis, and mild atrophy in two of the three patients without CNS prophylaxis), no significant clinical abnormalities or EEG changes were detectable. While this group of patients is small, it is a unique cohort: adults who have received cranial irradiation in the absence of known brain tumor with long term follow-up. The precise role of CNS prophylaxis in the etiology of CT abnormalities is unclear, and the lack of clinically significant changes would suggest no contraindication to PCI when indicated

    We have used ultra-low light level fluorescence microscopy to examine the suggestion that the relatively poor response of human basal cell carcinomas (BCC) to topical 5-aminolaevulinic acid (ALA)-based photodynamic therapy (PDT) arises from limited drug penetration into the lesion. The distribution of ALA-induced protoporphyrin IX (PpIX) in human BCC and Bowen's disease was examined and, in almost all cases, was found to be most intense in those regions of tumor immediately adjacent to the dermis. This distribution was independent of tumor type, and did not appear to be affected by tumor depth in the skin. It is suggested that ALA penetration may not limit the efficacy of ALA-PDT in the treatment of BCC. Failure of superficial ALA-based PDT in basal cell carcinoma may, instead, be related to the histological structure of this type of lesion.

  19. Body composition by computed tomography as a predictor of toxicity in patients with renal cell carcinoma treated with sunitinib.

    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.

  20. Risk factors of distant metastasis in patients with squamous cell carcinoma of the uterine cervix treated with postoperative irradiation

    International Nuclear Information System (INIS)

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

    Renal cell carcinoma is the most common renal tumor in adults. Clear cell carcinoma represents 85% of all histological subtypes. In February 2012 a 72-year-old woman came to our department due to the appearance of massive hemoptysis and pharyngodinia. Previously, this patient was diagnosed with a renal cell carcinoma treated with left nephrectomy. We observed an exophytic, grayish, and ulcerated mass in the left tonsillar lodge and decided to subject the patient to an immediate tonsillectomy....

    Sarcomatoid renal cell carcinoma (SRCC) is an aggressive tumor variant thought to arise predominantly from differentiation of clear cell carcinoma. A few reports of SRCC asso-ciated with non-clear cell tumors led to the presumption that SRCC may arise from any renal cell carcinoma, although direct evidence of this is lacking. We report a case of a 70-year-old male patient, who presented with acute left upper quadrant abdominal pain and was diagnosed to have SRCC after pathological examination...

  6. MVP expression in the prediction of clinical outcome of locally advanced oral squamous cell carcinoma patients treated with radiotherapy

    International Nuclear Information System (INIS)

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

    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.

    Our knowledge of renal cell carcinoma (RCC) is rapidly expanding. For those who diagnose and treat RCC, it is important to understand the new developments. In recent years, many new renal tumors have been described and defined, and our understanding of the biology and clinical correlates of these tumors is changing. Evolving concepts in Xp11 translocation carcinoma, mucinous tubular and spindle cell carcinoma, multilocular cystic clear cell RCC, and carcinoma associated with neuroblastoma are addressed within this review. Tubulocystic carcinoma, thyroid-like follicular carcinoma of kidney, acquired cystic disease-associated RCC, and clear cell papillary RCC are also described. Finally, candidate entities, including RCC with t(6;11) translocation, hybrid oncocytoma/chromophobe RCC, hereditary leiomyomatosis and RCC syndrome, and renal angiomyoadenomatous tumor are reviewed. Knowledge of these new entities is important for diagnosis, treatment and subsequent prognosis. This review provides a targeted summary of new developments in RCC. PMID:24364021

  15. Laryngeal adenocystic carcinoma treated by proton therapy

    International Nuclear Information System (INIS)

    Adenocystic carcinoma most commonly develops in the major salivary glands, on the other hand it is rare for adenocystic carcinoma to develop in the larynx. We report a case of adenocystic carcinoma in the larynx. A 54-year-old male was hospitalized with symptoms of hoarseness and dyspnea on exertion. He presented a tumor that developed at the base of the right arytenoid, and covered over the glottis. It was confirmed to be adenocystic carcinoma (solid type) by biopsy. Positron emission tomography (PET)-CT also revealed a left cervical lymph node metastasis and multiple pulmonary metastases (T1N2cM1). He was treated with proton therapy to the larynx to prevent airway obstruction by growth of the tumor and to preserve the larynx because he had uncontrollable pulmonary metastasis. Although the tumor vanished after the treatment, one month later he had halitosis, dyspnea and bilateral vocal cord palsy. Despite administration of an antibacterial drug and steroid, there was no improvement to the narrowness of the glottis. A tracheotomy was therefore performed three months after the proton therapy. PET-CT, which was performed after the tracheotomy, suggested growth of the residual tumor or laryngeal radionecrosis. This study confirmed that proton therapy is effective for adenocystic carcinoma in the larynx. However, proton therapy also was found to cause laryngeal radionecrosis. These results indicate the importance of evaluating the side effects of radiation therapy and providing that information to the patient. (author)

    Background: Predicting the efficacy of antiangiogenic therapy would be of clinical value in patients (pts) with metastatic renal cell carcinoma (mRCC). We tested the hypothesis that circulating endothelial cell (CEC), bone marrow-derived CD45dimCD34+VEGFR2+ progenitor cell or plasma angiogenic factor levels are associated with clinical outcome in mRCC pts undergoing treatment with tyrosine kinase inhibitors (TKI). Methods: Fifty-five mRCC pts were prospectively monitored at baseline (day 1) and day 14 during treatment (46 pts received sunitinib and 9 pts received sorafenib). Circulating endothelial cells (CD45−CD31+CD146+7-amino-actinomycin (7AAD)− cells) were measured in 1 ml whole blood using four-color flow cytometry (FCM). Circulating CD45dimCD34+VEGFR2+7AAD− progenitor cells were measured in progenitor-enriched fractions by four-color FCM. Plasma VEGF, sVEGFR2, SDF-1α and sVCAM-1 levels were determined by ELISA. Correlations between baseline CEC, CD45dimCD34+VEGFR2+7AAD− progenitor cells, plasma factors, as well as day 1–day 14 changes in CEC, CD45dimCD34+VEGFR2+7AAD− progenitor, plasma factor levels, and response to TKI, progression-free survival (PFS) and overall survival (OS) were examined. Results: No significant correlation between markers and response to TKI was observed. No association between baseline CEC, plasma VEGF, sVEGFR-2, SDF-1α, sVCAM-1 levels with PFS and OS was observed. However, baseline CD45dimCD34+VEGFR2+7AAD− progenitor cell levels were associated with PFS (P=0.01) and OS (P=0.006). Changes in this population and in SDF-1α levels between day 1 and day 14 were associated with PFS (P=0.03, P=0.002). Changes in VEGF and SDF-1α levels were associated with OS (P=0.02, P=0.007). Conclusion: Monitoring CD45dimCD34+VEGFR2+ progenitor cells, plasma VEGF and SDF-1α levels could be of clinical interest in TKI-treated mRCC pts to predict outcome. PMID:21386843

    Purpose: To report atypical clinical behavior observed in human papillomavirus (HPV)-related oropharyngeal carcinoma (OPC) treated with radiotherapy. Methods and Materials: A retrospective cohort study was conducted for all newly diagnosed OPC cases treated with radiotherapy on July 1, 2003 to April 30, 2009. HPV positivity was determined by p16 immunostaining in tumors. The incidence of additional malignancies and the pattern of distant metastases (DMs) were compared between the HPV-positive (HPV+) and HPV-negative (HPV-) cohorts. Results: HPV status was evaluated in 318 of 613 consecutive OPC cases (52%), showing 236 HPV+ and 82 HPV- patients. Compared with HPV-, HPV+ cases were less likely to have additional malignancies (prior: 11% vs. 20%, p = 0.038; synchronous: 1% vs. 9%, p = 0.001; metachronous: 6% vs. 16%, p = 0.003). Whereas the majority (10 of 12) of HPV- additional head-and-neck (HN) mucosal malignancies were in the oral cavity, there was none (0 of 7) in the HPV+ cohort (p < 0.001). HPV+ synchronous HN second primaries (SPs) were in the supraglottis, post-cricoid, and nasopharynx; metachronous HN SPs were in the glottis, supraglottis, and ethmoid plus glottis/post-cricoid region. All SPs that could be tested were HPV+. There was no difference in DM rate (10% vs. 15%, p = 0.272), but HPV+ DMs were more likely to involve multiple organs (46% vs. 0%, p = 0.005) and unusual sites. Conclusions: This study reports atypical clinical behavior seen in HPV+ OPC, including multicentric lesions in HN mucosa and DM to multiple organs and unusual sites. The frequency of these events is low, but they may have clinical implications. The routine assessment of HPV status for all OPC is warranted.

    2011-12-01

    Full Text Available Squamous cell carcinoma (SCC is the second most common type of skin cancer with potential risks for metastasis and recurrence if left untreated or incompletely excised. This case series study was designed to determine the frequency of incompletely excised SCCs and the related risk factors. A total of 273 SCCs (253 patients excised in Razi dermatology hospital of Tehran from 2006-2008, were evaluated and were analyzed by Chi-square or t-test. The incidence of incomplete excision was 17.58 % and deep margin involvement was observed in 73% of lesions. Risk factors associated with incomplete excision of SCCs were being female, location of the tumors (in particular the lesions on lateral canthus, upper lip, foot, forehead, cheek, neck, nose and ear, large lesions and grafting method of repair. There was no statistically significant difference for the age, degree of histological differentiation, childhood history of radiotherapy for tinea capitis and the type of anesthesia. More care should be taken for high risk SCCs as complete excision avoids potential risk of recurrence and metastasis.

    2014-01-01

    We report a case of squamous cell carcinoma of external auditory canal in an Omani man with oculocutaneous albinism. The disease mimicked inflammatory process revealing positive cultures for various microorganisms during the course of his illness. He was eventually biopsied to rule out atypical infective process or presence of malignancy. He was staged as T4N0M0 and treated with radical doses of palliative radiation therapy which was very well tolerated and resulted in a complete resolution of disease clinically and a major soft tissue response on radiological imaging. Another unique finding was the absence of epidermal growth factor receptor (EGFR) protein overexpression in the tumour specimen. More than 90% of mucosal squamous cell carcinoma (SCC) involving the head and neck region overexpress the EGFR protein in normal skin patients. SCC is the predominant cutaneous malignancy in albinos, and the presence of EGFR protein overexpression in cutaneous SCC is believed to be 56–58% in normal skin patients. The scientific literature is scarce on reporting incidence of EGFR overexpression in either cutaneous or mucosal SCC in albinos, and it remains to be defined whether being albino is the cause for its absence.

  3. Oropharyngeal Squamous Cell Carcinoma Treated With Radiotherapy or Radiochemotherapy: Prognostic Role of TP53 and HPV Status

    International Nuclear Information System (INIS)

    Purpose: To study the prognostic value of the TP53 mutation and human papilloma virus (HPV) status in oropharyngeal squamous cell carcinoma (OPSCC). Methods and materials: The TP53 mutation and HPV status were analyzed in 78 cases of locoregionally advanced OPSCC. The possible correlation of these factors with locoregiownal control, relapse-free survival, disease-specific survival, and overall survival (OS) was also investigated. Results: Of these 78 cases, 22 had disruptive and 22 had non-disruptive (silent) TP53 mutations; the remaining 34 cases had wild-type (WT) TP53. HPV 16 DNA was found in 9 cases (11%), but all HPV-positive (HPV+) cases carried a functional p53 protein, except for 1 case that had a silent mutation. HPV+ patients fared better than HPV-negative (HPV-) patients in terms of all survival parameters, with highly statistically significant differences between the groups. Specifically, no distant metastases were observed in the HPV+ patients, whereas they occurred in 17% of the HPV- patients. However, no difference was observed between the WT TP53 and mutation group, even when this was analyzed in terms of disruptive and non-disruptive mutations. Regardless, treatment with chemotherapy nearly doubled the 5-year OS rates, both in the mutation (42% vs. 22%) and WT (30 vs. 16%) group, but only the mutation group showed improvement in all survival parameters. In addition, the second tumor-free 5-year survival rate was 72% in HPV- cases, but no second tumors were observed in HPV+ and WT p53 cases. Conclusions: Patients with HPV+ OPSCC have an excellent prognosis after radiochemotherapy, but cisplatin-based chemotherapy may not confer a satisfactory outcome, especially in WT cases, thereby justifying the additional or alternative use of taxanes and epidermal growth factor receptors inhibitors. Uncommon distant metastases and second tumors in the HPV+ group may be cause for clinicians to review the follow-up policies in these patients.

  4. Prognostic stratification of patients with advanced renal cell carcinoma treated with sunitinib: comparison with the Memorial Sloan-Kettering prognostic factors model

    International Nuclear Information System (INIS)

    The treatment paradigm in advanced renal cell carcinoma (RCC) has changed in the recent years. Sunitinib has been established as a new standard for first-line therapy. We studied the prognostic significance of baseline characteristics and we compared the risk stratification with the established Memorial Sloan Kettering Cancer Center (MSKCC) model. This is a retrospective analysis of patients treated in six Greek Oncology Units of HECOG. Inclusion criteria were: advanced renal cell carcinoma not amenable to surgery and treatment with Sunitinib. Previous cytokine therapy but no targeted agents were allowed. Overall survival (OS) was the major end point. Significance of prognostic factors was evaluated with multivariate cox regression analysis. A model was developed to stratify patients according to risk. One hundred and nine patients were included. Median follow up has been 15.8 months and median OS 17.1 months (95% CI: 13.7-20.6). Time from diagnosis to the start of Sunitinib (<= 12 months vs. >12 months, p = 0.001), number of metastatic sites (1 vs. >1, p = 0.003) and performance status (PS) (<= 1 vs >1, p = 0.001) were independently associated with OS. Stratification in two risk groups ('low' risk: 0 or 1 risk factors; 'high' risk: 2 or 3 risk factors) resulted in distinctly different OS (median not reached [NR] vs. 10.8 [95% confidence interval (CI): 8.3-13.3], p < 0.001). The application of the MSKCC risk criteria resulted in stratification into 3 groups (low and intermediate and poor risk) with distinctly different prognosis underlying its validity. Nevertheless, MSKCC model did not show an improved prognostic performance over the model developed by this analysis. Studies on risk stratification of patients with advanced RCC treated with targeted therapies are warranted. Our results suggest that a simpler than the MSKCC model can be developed. Such models should be further validated

  7. Incidence of bowel wall oedema on computed tomography exams and association with diarrhoea in renal cell carcinoma patients treated with sunitinib

    International Nuclear Information System (INIS)

    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.)

    Full Text Available Everolimus is an orally administered inhibitor of the mammalian target of rapamycin (mTOR recommended for patients with metastatic renal cell carcinoma (mRCC who progressed on previous vascular endothelial growth factor (VEGF receptor-tyrosine kinase inhibitor therapy. Efficacy of everolimus in patients who progressed on anti-VEGF monoclonal antibody bevacizumab is unknown. We did a multicenter prospective trial of everolimus in patients with mRCC whose disease had progressed on bevacizumab ± interferon alpha (IFN. Patients with clear-cell mRCC which had progressed on bevacizumab ± IFN received everolimus 10 mg once daily. The primary end point was the proportion of patients remaining progression-free for 56 days, and a two-stage Simon design was used, with 80 % power and an alpha risk of 5 %. This study is registered with ClinicalTrials.gov, number NCT02056587. From December 2011 to October 2013, a total of 37 patients (28 M, 9 F were enrolled. Median age was 60.5 years (range 41-66, 11 % had Eastern Cooperative Oncology Group Performance Status (ECOG PS > 2, and Memorial Sloan-Kettering Cancer Center (MSKCC favorable/intermediate risk was 38/62 %. Five (14 % patients had a confirmed partial response and 26 (70 % patients had a stable disease. Median progression-free survival was 11.5 months (95 % CI, 8.8–14.2. Median overall survival was not reached. No grade 3 or 4 treatment-related toxicities were observed. The most common grade 2 adverse events were fatigue (19 % and pneumonitis (8 %. Everolimus demonstrated a favorable toxicity profile and promising anti-tumor activity as a second-line therapy in metastatic renal cell carcinoma (RCC patients previously treated with bevacizumab ± IFN.

  10. Papillary renal cell carcinoma

    International Nuclear Information System (INIS)

    Between 1976 and 1987, 395 patients with kidney tumors were studied with radiological techniques and sonography. In 37 cases (9.4%) histopathology diagnosed pure papillary renal cell carcinoma. Analyzing the radiographic patterns of these neoplasms, the authors observed constantly diminished vascularity (100%) frequent calcifications (35.1%) and necrotic areas (51.3%). Such X-ray features are not specific: nevertheless, their coexistence is strongly suggestive of papillary renal cell cancer. No consistent US pattern was found; however, necrotic areas were easily demonstrated in most cases. It must be stressed how patients with papillary carcinoma experienced a longer post-operative survival; it has not yet been established whether such favorable behavior is due to low biological aggressiveness or to earlier diagnosis

  14. The importance of immunohistochemical expression of EGFr in squamous cell carcinoma of the oral cavity treated with surgery and postoperative radiotherapy

    International Nuclear Information System (INIS)

    Purpose: The aim of this study was to investigate the prognostic significance of epidermal growth factor (EGFr) expression in oral cavity squamous cell carcinoma (OCSCC) treated with curative surgery and postoperative radiotherapy. Methods and Materials: This retrospective study included 165 OCSCC patients. The expression of EGFr was assessed on paraffin-embedded tissue of the primary tumor by immunohistochemistry using a monoclonal antibody directed against EGFr. Intensity of the EGFr expression was scored by two authors blinded for the clinical outcome. Results: In the univariate analysis, locoregional control at 3 years (LRC) in the EGFr-negative cases was 69% compared with 77% in the EGFr-positive cases (p 0.22). In the multivariate analysis for local control, a significant interaction was found between EGFr and overall treatment time of radiation (OTT). After stratification for EGFr expression, the OTT was of no importance in the EGFr-negative cases, whereas a significant difference in LRC was found in the EGFr-positive cases, in which the LRC after 3 years was 69% and 94% in case of an OTT of 0-42 days and >42 days, respectively (p = 0.009; hazard ratio = 3.42; 95% confidence interval, 1.28-8.96). No significant association was found between EGFr expression and overall survival. Conclusions: In the present study, no association was found between EGFr expression and outcome regarding locoregional control and overall survival. However, the results of the present study suggest that patients with squamous cell carcinoma of the oral cavity with high EGFr expression benefit more from a reduction of the overall treatment time of postoperative radiation than those with low EGFr expression

    Treatment of anorectal Buschke-Löwenstein tumor (BLT) with squamous cell carcinoma (SCC) transformation is not univocal given the rarity of the disease. BLT is characterized by its large size and tendency to infiltrate into underlying tissues. Malignant transformation can occur and it is important to identify the presence of neoplastic foci to decide the proper treatment. Our aim was to assess the effectiveness of neo-adjuvant chemo-radiation therapy (CRT) and local excision in order to avoid abdomino-perineal resection (APR). Three cases of anorectal BLT with SCC transformation are presented. All patients were HIV positive and treated with antiretroviral drugs. They underwent preoperative endoanal ultrasound, biopsies, total body tomography and anal brushing. Treatment consisted of neo-adjuvant chemo-radiation therapy (45 Gy to the pelvis plus a boost with 14.40 Gy to the primary tumor for a total of 59.40 Gy, and mitomycin-C in bolus on the first day, plus 5-fluorouracil by continuous infusion in the first and in the sixth week) and subsequent local surgical excision. During the follow-up, patients were subjected to the same preoperative diagnostic investigations and high resolution anoscopy. All patients showed a complete regression of the lesion after CRT and were treated by local surgical excision, thus avoiding permanent colostomy. In conclusion neo-adjuvant chemo-radiation therapy with local surgical excision could be considered an effective therapy in the treatment of anorectal BLT with SCC transformation to avoid APR.

  17. Use of serum squamous cell carcinoma antigen for follow-up monitoring of cervical cancer patients who were treated by concurrent chemoradiotherapy

    International Nuclear Information System (INIS)

    To investigate the significance of monitoring the levels of the serum squamous cell carcinoma antigen (SCC-Ag) for the detection of recurrent disease in patients with cervical cancer treated by concurrent chemoradiotherapy. The records of 112 patients with cervical cancer were reviewed. Serum SCC-Ag levels were measured at regular follow-up visits. A SCC-Ag level of 2 ng/mL was considered the upper limit of normal. Biochemical failure was defined as two consecutively increasing SCC-Ag values above normal. Recurrent disease was confirmed by histologic and radiographic studies. Eighteen patients (16%) developed recurrent disease. Sixteen patients had initially elevated SCC-Ag, post-treatment normalization of SCC-Ag, and tumor recurrence. The SCC-Ag difference (ΔSCC-Ag), defined as the difference between the last value after two consecutively increases above normal and the value immediately before the elevation, had good clinical performance in predicting cancer recurrence. The cutoff value of ΔSCC-Ag was 0.95 ng/mL. SCC-Ag is a relatively good method for the detection of disease recurrence in patients with cervical cancer who were treated by concurrent chemoradiotherapy

    Background The benefit of combined chemoradiation in elderly patients with human papillomavirus (HPV)-positive locally advanced oropharyngeal squamous cell carcinoma (SCC) must be balanced with the potential for higher toxicity rates. We performed a retrospective review of our institutional experience. Methods Patients 70 years or older with p16-positive oropharyngeal SCC treated with definitive chemoradiation from 2005 to 2013 were evaluated. Overall survival (OS), disease-free survival (DFS), and locoregional failure–free survival were calculated. Results Twenty-one eligible patients had a follow-up of 22.4 months. Estimated 5-year OS, DFS, and locoregional failure–free survival were 76.0%, 40%, and 95%, respectively. There was 1 death from acute toxicity, and 50% had unplanned hospitalizations. Sixty percent had late toxicity, and 6-month feeding tube dependence was 25%. Conclusion Elderly patients with HPV-positive locally advanced SCC of the oropharynx treated with definitive chemoradiation had good OS but high rates of acute and long-term toxicity. PMID:25899391

    Background: To examine whether nuclear NF-κB expression correlates with outcome in patients with head and neck squamous cell carcinoma (HNSCC) treated with primary chemoradiation therapy (CRT). Methods and Materials: Between 2007 and 2010, 101 patients with locally advanced primary HNSCC were treated with definitive simultaneous CRT. Pretreatment biopsy specimens were analyzed for NF-κB p65 (RelA) nuclear immunoreactivity. A sample was assigned to be positive with more than 5% positive nuclear expression. The predictive relevance of NF-κB and clinicopathologic factors for overall survival (OS), progression-free survival (PFS), local progression-free survival (LPFS), and metastasis-free survival (DMFS) was examined by univariate and multivariate analysis. Results: No significant differences between the groups were observed with regard to age, sex, total radiation dose, fractionation mode, total chemotherapy applied, T stage or grading. Patients with p65 nuclear positive biopsy specimens showed significantly a higher rate of lymph node metastasis (cN2c or cN3 status, P=.034). Within a mean follow-up time of 25 months (range, 2.33-62.96 months) OS, PFS, and DMFS were significantly poorer in the p65 nuclear positive group (P=.008, P=.027, and P=.008, respectively). These correlations remained significant in multivariate analysis. Conclusion: NF-κB/p65 nuclear expression is associated with increased lymphatic and hematogenous tumor dissemination and decreased survival in HNSCC patients treated with primary CRT. Our results may foster further investigation of a predictive relevance of NF-κB/p65 and its role as a suitable target for a molecular-based targeted therapy in HNSCC cancer.

  3. The apparent diffusion coefficient of a primary lesion correlates with local failure of head and neck squamous cell carcinoma treated with radiotherapy. President award proceedings

    International Nuclear Information System (INIS)

    We prospectively investigated whether the value of the apparent diffusion coefficient (ADC) of a primary lesion prior to treatment correlated with local failure of head and neck squamous cell carcinoma (HNSCC) following radiotherapy. In 17 patients who underwent radiotherapy for primary HNSCC, we compared variables considered to affect local failure, including parameters related to magnetic resonance (MR) imaging, such as ADC and its alteration ratio, between cases of local failure and controls and analyzed survival among those patients in whom the variables differed or demonstrated association with local failure. We also retrospectively analyzed variables in a validation study of 40 patients. In the prospective study, pretreatment values of ADChigh (calculated with b-values of 300, 500, 750, and 1000 s/mm2) alone showed significant association with local failure (P=0.0186). In the validation study, pretreatment values of tumor volume (P=0.0217) and ADChigh (P=0.0001) were significantly associated with local failure. Pretreatment ADChigh was superior to pretreatment tumor volume regarding association with local failure. These results suggest that pretreatment values of both ADC obtained using high b-values and tumor volume correlate with local failure of HNSCC treated with radiotherapy. (author)

  4. Outcomes of patients with loco-regionally recurrent or new primary squamous cell carcinomas of the head and neck treated with curative intent reirradiation at Mayo Clinic

    International Nuclear Information System (INIS)

    We reviewed outcomes of patients with loco-regionally recurrent (LRR) or new primary (NP) squamous cell carcinoma of the head and neck (SCCHN) treated at our institution with reirradiation (RRT). Patients received definitive RRT (DRRT) or post-operative RRT following salvage surgery (PRRT) from 2003 to 2011. Measured survival outcomes included loco-regional relapse free survival (LRFS) and overall survival (OS). Among 81 patients (PRRT, 42; DRRT, 39), median PRRT and DRRT doses were 60 Gy (12–70 Gy) and 69.6 Gy (48–76.8 Gy). The majority of patients received IMRT-based RRT (n = 77, 95 %). With median follow-up of 78.1 months (95 % CI, 56–96.8 months), 2-year OS was 53 % with PRRT and 48 % with DRRT (p = 0.12); 23 % of patients were alive at last follow-up. LRFS at 2 years was 60 %, and did not differ significantly between PRRT and DRRT groups. A trend toward inferior LRFS was noted among patients receiving chemotherapy with RRT versus RRT alone (p = 0.06). Late serious toxicities were uncommon, including osteoradionecrosis (2 patients) and carotid artery bleeding (1 patient, non-fatal). OS of PRRT- and DRRT-treated patients in this series appears superior to the published literature. We used IMRT for the majority of patients, in contrast to several series and trials previously reported, which may account in part for this difference. Future studies should seek to improve outcomes among patients with LRR/NP SCCHN via alternative therapeutic modalities such as proton radiotherapy and by incorporating novel systemic agents

    Use of angiotensin system inhibitors (ASIs; angiotensin receptor blockers or angiotensin-converting enzyme inhibitors) has been reported to be associated with improved survival in metastatic renal cell carcinoma (mRCC), particularly when used with vascular endothelial growth factor-targeted therapies. This study was a secondary pooled analysis of two Phase III randomized controlled trials (RCTs) of patients with mRCC: NCT00334282 comparing pazopanib to placebo and NCT00720941 comparing pazopanib to sunitinib. ASI users were defined as patients using an ASI at baseline. Association with overall survival (OS; primary outcome) and progression-free survival (PFS) was evaluated using Cox proportional hazards regression. The association was adjusted in multivariable analysis for baseline systolic blood pressure (SBP), use of other antihypertensive drugs and prognostic factors comprising the Heng risk criteria for mRCC. Of 1,545 patients pooled from the two RCTs, 649 (42%) were using one or more antihypertensive drugs at baseline, 385 (59%) of which were using an ASI. In the multivariable analysis of patients using pazopanib or sunitinib, no significant association was observed between baseline ASI use and OS (hazard ratio [HR] 0.97 [95% confidence interval (CI) 0.80-1.18], p = 0.80) or PFS (HR 0.88 [95% CI 0.73-1.06], p = 0.17). Exploratory subgroup analysis of NCT00720941 highlighted that the effect of baseline ASI use on OS may differ between patients treated with sunitinib and pazopanib. In conclusion, use of ASIs at baseline was not a significant independent prognostic factor for improved survival in a pooled analysis of mRCC patients treated with pazopanib or sunitinib.

    Full Text Available We should accept that there are attempts in all over the world to do much less invasive treatments especially in surgical procedures. Nowadays, one of the interest areas of urologists is conservative management of upper urinary tract urothelial cancers (UUTCs. Is nephroureterectomy an overtreatment for all cases or which cases are eligible for minimally invasive therapy in UUTC. Recently, the European Association of Urology guidelines accepted conservative endoscopic treatment using ureterenoscopy for a selected group of UUTC patients with low-volume, low-grade, and low-stage disease. This study tried to explain a new technique, confocal laser endomicroscopy (CLE, for increasing accuracy of sampling in UUTC and improving the conservative management. CLE is an ultrahigh-resolution microscopy technique that allows imaging of tissue at a depth of 400 µm. A negative point for CLE is the sensitivity to tissue movement leading to motion artifacts that could result in blurred images. In other studies, the benefit of CLE was shown in colon, gastric and bronchial pathologies which are luminal organs like urinary tract. Eleven patients were enrolled in this study. Four patients were previously treated endoscopically and one patient had positive cytology with no evidence of a disease in the bladder. A digital ureteroscope Flex-XC was used in all cases. After fluorescein injection, real time video sequences were acquired. Biopsies were obtained from the suspicious lesions. According to CLE findings, there were three high-grade, seven low-grade tumors and one negative tumor. Biopsy findings revealed with four not reliable, one inflammation (negative one in CLE, one dysplasia, four low-grade tumors and one highgrade tumor. It is very hard to comment on a new technique with a small amount of patients. May be it is better to say the cliché words: This study should be confirmed or validated by wide variety of studies. In addition, although this study showed

  8. FAZA PET/CT hypoxia imaging in patients with squamous cell carcinoma of the head and neck treated with radiotherapy: Results from the DAHANCA 24 trial

    International Nuclear Information System (INIS)

    Purpose: Hypoxia is a cause of resistance to radiotherapy, especially in patients with head and neck squamous cell carcinoma (HNSCC). The purpose of this study was to evaluate 18F-fluoroazomycin arabinoside (FAZA) positron emission tomography (PET)/computed tomography (CT) hypoxia imaging as a prognostic factor in HNSCC patients receiving radiotherapy. Material and methods: Forty patients with HNSCC treated with radiotherapy (66–76 Gy) were included. Static FAZA PET/CT imaging 2 h post injection was conducted prior to irradiation. The hypoxic volume (HV) was delineated using a tumor-to-muscle value ⩾1.4. In 13 patients, a repetitive FAZA PET/CT scan was conducted during the radiotherapy treatment. Results: A hypoxic volume could be identified in 25 (63%) of the 40 tumors. FAZA PET HV varied considerably with a range from 0.0 to 30.9 (median: 0.3) cm3. The Tmax/Mmed ranged from 1.1 to 2.9 (median: 1.5). The distribution of hypoxia among the Human Papillomavirus (HPV) positive (12/16) and negative (13/24) tumors was not significant different. In the FAZA PET/CT scans performed during radiotherapy, hypoxia could be detected in six of the 13 patients. For these six patients the location of HV remained stable in location during radiotherapy treatment, though the size of the HV decreased. In 30 patients a positive correlation was detected between maximum FAZA uptake in the primary tumor and the lymph node. During a median follow up of 19 months a significant difference in disease free survival rate with 93% for patients with non hypoxic tumors and 60% for patients with hypoxic tumors could be detected. Conclusion: This study emphasizes the role of FAZA PET/CT imaging as a suitable assay with prognostic potential for detection of hypoxia in HNSCC.

    2014-08-01

    Purpose: A subset of patients with oropharyngeal squamous cell carcinoma (OP-SCC) managed with transoral robotic surgery (TORS) and postoperative radiation therapy (PORT) developed soft tissue necrosis (STN) in the surgical bed months after completion of PORT. We investigated the frequency and risk factors. Materials and Methods: This retrospective analysis included 170 consecutive OP-SCC patients treated with TORS and PORT between 2006 and 2012, with >6 months' of follow-up. STN was defined as ulceration of the surgical bed >6 weeks after completion of PORT, requiring opioids, biopsy, or hyperbaric oxygen therapy. Results: A total of 47 of 170 patients (28%) had a diagnosis of STN. Tonsillar patients were more susceptible than base-of-tongue (BOT) patients, 39% (41 of 104) versus 9% (6 of 66), respectively. For patients with STN, median tumor size was 3.0 cm (range 1.0-5.6 cm), and depth of resection was 2.2 cm (range 1.0-5.1 cm). Median radiation dose and dose of fraction to the surgical bed were 6600 cGy and 220 cGy, respectively. Thirty-one patients (66%) received concurrent chemotherapy. Median time to STN was 2.5 months after PORT. All patients had resolution of STN after a median of 3.7 months. Multivariate analysis identified tonsillar primary (odds ratio [OR] 4.73, P=.01), depth of resection (OR 3.12, P=.001), total radiation dose to the resection bed (OR 1.51 per Gy, P<.01), and grade 3 acute mucositis (OR 3.47, P=.02) as risk factors for STN. Beginning May 2011, after implementing aggressive avoidance of delivering >2 Gy/day to the resection bed mucosa, only 8% (2 of 26 patients) experienced STN (all grade 2). Conclusions: A subset of OP-SCC patients treated with TORS and PORT are at risk for developing late consequential surgical bed STN. Risk factors include tonsillar location, depth of resection, radiation dose to the surgical bed, and severe mucositis. STN risk is significantly decreased with carefully avoiding a radiation dosage of >2 Gy/day to

  13. Effect of smoking on oxygen delivery and outcome in patients treated with radiotherapy for head and neck squamous cell carcinoma – A prospective study

    International Nuclear Information System (INIS)

    Background: Head and neck cancer patients with high hemoglobin respond better to irradiation compared to patients with low hemoglobin possibly due to hypoxia induced radioresistance. The hemoglobin level is, however, a crude indicator of the amount of oxygen available to the tissue and may be influenced by a number of factors, smoking being of potential importance. The aim of the present study was to examine the effect of smoking on available oxygen to tumors and the effect on outcome in head and neck cancer patients treated with radiotherapy in a prospective study. Materials and methods: A total of 232 consecutive patients with squamous cell carcinoma of the larynx, pharynx and oral cavity completed questionnaires on smoking habits prior to treatment. Venous blood samples were collected before and/or during treatment to determine the hemoglobin and carboxyhemoglobin level. Patients were treated with primary curative radiotherapy 62–68 Gy, 2 Gy/fx, 5 fx/week. Results: All but 12 patients had a history of smoking, 35 were long term quitters, 23 recent quitters, 54 moderate smokers and 108 heavy smokers (>1 pack/day). There was no relationship between total hemoglobin and carboxyhemoglobin, but effective hemoglobin and carboxyhemoglobin were linearly correlated. The amount of carboxyhemoglobin increased with increasing smoking status. Actuarial 5-year univariate analysis showed that heavy smokers had a significantly reduced probability of loco-regional control (44% vs. 65%, p = 0.001), disease-specific (56% vs. 77%, p = 0.003) and overall survival (39% vs. 66%, p = 0.0004) compared to non-smoking patients. Multivariate analyses showed that patients characterized as non-smokers, with low T and N classifications and high hemoglobin level had the best outcome measurements. A rise in carboxyhemoglobin significantly decreased the probability of loco-regional control and each additional pack year increased the risk of death. Smokers and former smokers develop secondary

    Purpose/Objective(s): This study aimed to analyze outcomes in a multi-institutional cohort of patients with advanced or recurrent renal cell carcinoma (RCC) who were treated with intraoperative radiation therapy (IORT). Methods and Materials: Between 1985 and 2010, 98 patients received IORT for advanced or locally recurrent RCC at 9 institutions. The median follow-up time for surviving patients was 3.5 years. Overall survival (OS), disease-specific survival (DSS), and disease-free survival (DFS) were estimated with the Kaplan-Meier method. Chained imputation accounted for missing data, and multivariate Cox hazards regression tested significance. Results: IORT was delivered during nephrectomy for advanced disease (28%) or during resection of locally recurrent RCC in the renal fossa (72%). Sixty-nine percent of the patients were male, and the median age was 58 years. At the time of primary resection, the T stages were as follows: 17% T1, 12% T2, 55% T3, and 16% T4. Eighty-seven percent of the patients had a visibly complete resection of tumor. Preoperative or postoperative external beam radiation therapy was administered to 27% and 35% of patients, respectively. The 5-year OS was 37% for advanced disease and 55% for locally recurrent disease. The respective 5-year DSS was 41% and 60%. The respective 5-year DFS was 39% and 52%. Initial nodal involvement (hazard ratio [HR] 2.9-3.6, P<.01), presence of sarcomatoid features (HR 3.7-6.9, P<.05), and higher IORT dose (HR 1.3, P<.001) were statistically significantly associated with decreased survival. Adjuvant systemic therapy was associated with decreased DSS (HR 2.4, P=.03). For locally recurrent tumors, positive margin status (HR 2.6, P=.01) was associated with decreased OS. Conclusions: We report the largest known cohort of patients with RCC managed by IORT and have identified several factors associated with survival. The outcomes for patients receiving IORT in the setting of local recurrence compare favorably to

    Purpose: To examine the prognostic significance of c-Met expression in relation to p16 and epidermal growth factor receptor (EGFR) in patients with locally advanced head and neck squamous cell carcinoma (HNSCC) treated with definitive concurrent chemoradiation. Methods and Materials: Archival tissue from 107 HNSCC patients treated with chemoradiation was retrieved, and a tissue microarray was assembled. Immunohistochemical staining of c-Met, p16, and EGFR was performed. c-Met expression was correlated with p16, EGFR, clinical characteristics, and clinical endpoints including locoregional control (LRC), distant metastasis (DM), disease-free survival (DFS), and overall survival (OS). Results: Fifty-one percent of patients were positive for p16, and 53% were positive for EGFR. Both p16-negative (P≤.001) and EGFR-positive (P=.019) status predicted for worse DFS. Ninety-three percent of patients stained positive for c-Met. Patients were divided into low (0, 1, or 2+ intensity) or high (3+ intensity) c-Met expression. On univariate analysis, high c-Met expression predicted for worse LRC (hazard ratio [HR] 2.27; 95% CI, 1.08-4.77; P=.031), DM (HR 4.41; 95% CI, 1.56-12.45; P=.005), DFS (HR 3.00; 95% CI, 1.68-5.38; P<.001), and OS (HR 4.35; 95% CI, 2.13-8.88; P<.001). On multivariate analysis, after adjustment for site, T stage, smoking history, and EGFR status, only high c-Met expression (P=.011) and negative p16 status (P=.003) predicted for worse DFS. High c-Met expression was predictive of worse DFS in both EGFR-positive (P=.032) and -negative (P=.008) patients. In the p16-negative patients, those with high c-Met expression had worse DFS (P=.036) than did those with low c-Met expression. c-Met expression was not associated with any outcome in the p16-positive patients. Conclusions: c-Met is expressed in the majority of locally advanced HNSCC cases, and high c-Met expression predicts for worse clinical outcomes. High c-Met expression predicted for worse DFS in p16

    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.

The results showed that high concentration of H2O2 (600 μM could decrease cell viability, inhibit cell proliferation, induce cell cycle arrest, and finally promote cell apoptosis. Conversely, no significant effects could be found under treatment with low concentration (30 μM. miRNAs array analysis identified 131 differentially expressed miRNAs (125 were upregulated and 6 were downregulated and predicted 13504 putative target genes of the deregulated miRNAs. Gene ontology (GO analysis revealed that the putative target genes were associated with H2O2-induced cell growth arrest and apoptosis. The subsequent bioinformatics analysis indicated that H2O2-response pathways, including MAPK signaling pathway, apoptosis, and pathways in cancer and cell cycle, were significantly affected. Overall, these results provided comprehensive information on the biological function of H2O2 treatment in HepG2 cells. The identification of miRNAs and their putative targets may offer new diagnostic and therapeutic strategies for liver cancer.

  13. Squamous cell carcinoma of the oral cavity

    International Nuclear Information System (INIS)

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

  16. Impact of the prophylactic gastrostomy for unresectable squamous cell head and neck carcinomas treated with radio-chemotherapy on quality of life: Prospective randomized trial

    International Nuclear Information System (INIS)

    Background and purpose: Concomitant radio-chemotherapy is the gold standard treatment for unresectable head and neck carcinomas. Placement of prophylactic gastrostomy has been proposed to provide adequate nutrition during the therapeutic sequence. The objectives of this study were to assess the impact of prophylactic gastrostomy on the 6-month quality of life, and to determine the factors related to this quality of life. Materials and methods: Design. randomized, controlled, open study ('systematic percutaneous gastrostomy' versus 'no systematic gastrostomy'). Patients. squamous cell head and neck carcinoma (stages III and IV, UICC 1997). Setting. oncological departments of French university teaching hospitals. Treatment. optimal concomitant radio-chemotherapy. Evaluations. T0 baseline evaluation, T1 during the treatment, T2 end of the treatment, and T3 6-month post-inclusion. Primary endpoint. 6-month quality of life (Qol) assessed using SF36, EORTC QLQ-C30, EORTC QLQ H and N35 questionnaires. Results: The Qol changes from baseline included a decline (T1 and T2) followed by an improvement (T3). Qol at 6 months was significantly higher in the group receiving systematic prophylactic gastrostomy (p = 10-3). Higher initial BMI and lower initial Karnofsky index were significant factors related to a higher 6-month Qol. Conclusions: The study results suggest that prophylactic gastrostomy improves post-treatment quality of life for unresectable head and neck cancer patients, after adjusting for other potential predictive quality of life factors.

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

  18. MRI analysis of renal cell carcinoma

    International Nuclear Information System (INIS)

    Objective: To analyze MRI manifestation and enhancement of renal cell carcinoma, and to improve the diagnosis of renal cell carcinoma. Methods: 48 cases of renal cell carcinoma proven by surgery and pathology were reviewed. MRI scans including T1WI, T2WI, TRUFI and contrast enhancement were carried out in all cases and dynamic contrast-enhanced MRI was performed in 15. Results: Of the 48 cases, there were clear cell carcinoma in 41, chromophobe cell carcinoma in 4 and papillary cell carcinoma in 3. The tumors were homogeneously T1 iso- or hypointense in 33 and heterogeneous in 15; homogeneously T2 hyperintense in 14, isointense in 6 and heterogeneous in 28 patients. Pseudocapsule was found in 10 cases. Contrast enhancement was homogeneous in 6, heterogeneous in 34, irregularly peripheral within the wall in 5, and homogeneously circular in 3. Conclusion: MRI can accurately diagnose renal cell carcinoma and help to determine the cell subsets. (authors)

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

    International Nuclear Information System (INIS)

    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 (p>0.10). 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. (orig.)

    2009-06-01

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

    In this study, immunotoxin (IT) was prepared by conjugating BAC5 and CT with SPDP. The effects of IT on NPC and its mechanisms were explored using double labeled with radioactive nuclides, immunography and electron microscope technique in vivo and in vitro. The specific concentration of BAC5 in the tumor area showed. The radioactivity rate of tumor/nontumor (T/NT) was up to 10.26. IT had cytotoxic effects both on the cultured CNE-2 cell line and tumor multicell spheroides. In vivo, the preliminary result indicated that IT also had a inhibitory action on the nude mice models bearing human NPC (Reported in another article). Under electron microscope, the necrosis and apoptosis of tumor cells were found. The membranes of most tumor cells were found intacted not or corrosined, some of them had the character of apoptosis, including reduce of tumor cells membrane villi, condensation of cytoplasm and pyknosis or cleavage of nuclear. There were many of apoptosis bodies, which were occasionally phagocytosed by tumor cells. The infiltration of immunocytoes in tumor tissue could be seen. The results indicated that BAC5 can specifically combine with NPC cells and BAC5-CT has the inhibitory effect on NPC in vitro and in vivo, mechanism of which may be related to the effects that ‘warhead' CT dissolute the membrane of tumor cells directly, or/and IT promote the infiltration of immunocytoes so as to induce the apoptosis of tumor cell.

    Background Axitinib, a selective and potent tyrosine kinase inhibitor of vascular endothelial growth factor receptors, was available to patients from Canada and Australia, prior to regulatory approval of axitinib in these countries, for treatment of clear-cell metastatic renal cell carcinoma (mRCC) after failure of one prior systemic regimen. Methods This single-arm, open-label study of axitinib evaluated the efficacy, safety, and quality of life (QoL) in patients with mRCC whose disease progressed after one prior systemic first-line regimen. Primary objective was objective response rate evaluated per Response Evaluation Criteria in Solid Tumors (RECIST) and Choi criteria. Progression-free survival, overall survival, safety, and QoL were secondary end points. Due to the small study size, analyses comprised of descriptive statistics. Results Fifteen patients were recruited, five from Canada and ten from Australia, over a limited recruitment period. Thirteen patients received sunitinib as prior therapy. All patients had clear-cell carcinoma, eleven had prior nephrectomy. Liver, lung, and lymph nodes were the most frequent sites of metastases; one patient had brain metastasis. Median time on axitinib was 118.0 days (range: 3.5–645.0 days); estimated survival probability at 12 months was 57.8%. Two (13.3%) patients had objective responses per RECIST versus nine (60.0%) per Choi criteria. Six patients had progressive disease based on RECIST versus three per Choi criteria. Nine (60.0%) events of progression or death occurred by the end of study, and three patients continued to receive the study drug. Fatigue (33%) and diarrhea (20%) were the most common grade ≥3 all-causality, treatment-emergent adverse events. The mean change in European Quality of Life – 5 Dimensions score from baseline to end of treatment was −0.0837. Conclusion The small number of patients and lack of a comparator arm limit the ability to draw definitive conclusions; however, safety and

    Full Text Available Abstract Background Bladder small cell carcinoma is an uncommon tumour. Through a retrospective study we will present the evolution of recurrent and metastatic disease and outcome of patients treated at Léon-Bérard Cancer Centre. Methods Only 15 patients having recurrent or metastatic bladder small cell carcinoma were treated at Léon-Bérard Cancer Centre between 1996 and 2007. The patients were divided in two groups: a mixed small cell carcinoma group (9 patients and a pure small cell carcinoma group (6 patients. All the records and informations related to treatment and outcome of the 15 patients were retrospectively analyzed. Various characteristics of small cell carcinoma were investigated. Results The median age of the 15 patients having recurrent or metastatic bladder small cell carcinoma and treated at Léon-Bérard Cancer Centre was 63 years and the disease was at stage IV for all cases. Nine patients were treated by chemotherapy. Four patients were treated by local radiotherapy (3 with radiotherapy without previous surgery and 1 with surgery followed by radiotherapy and chemotherapy. One patient was treated by whole brain radiotherapy. And one patient died before treatment. After 52.4 months median follow up, 12 patients died. Median overall survival was 7.6 months. Survival probability at 1 year was 33%. Median overall survival was 9.9 months in the mixed small cell carcinoma group, and was only 4.6 months in the pure small cell carcinoma group. Survival probability at 1 year in the mixed small cell carcinoma group was 44% as compared to 17% in the pure small cell carcinoma group (Log-rank test: p = 0.228. Conclusion Recurrent and metastatic bladder small cell carcinoma is associated with very poor prognosis. The pure bladder small cell carcinoma appears to have poorer outcome than the mixed bladder small cell carcinoma. Chemotherapy using platinum drugs is a mainstay treatment.

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

  7. Immunotherapy in renal cell carcinoma.

    Science.gov (United States)

    Bukowski, R M

    1999-06-01

    Patients with metastatic renal cell carcinoma continue to present a therapeutic challenge. Current therapeutic approaches involve surgery and various types of immunotherapy. The rationale for this latter form of therapy include the observations of spontaneous tumor regression, the presence of a T-cell-mediated immune response, and the tumor responses observed in patients receiving cytokine therapy. Analysis of prognostic factors in these patients demonstrates that clinical responses occur most frequently in individuals with good performance status. The cytokines interleukin-2 (IL-2, aldesleukin [Proleukin], interferon-alfa (Intron A, Roferon-A), or the combination produce responses in 15% to 20% of patients. Randomized trials suggest that administration of interferon-alfa may result in a modest improvement in median survival. Investigation of the molecular genetics of renal cell carcinoma and the presence of T-lymphocyte immune dysregulation have suggested new therapeutic strategies. Further preclinical and clinical studies investigating inhibitors of angiogenesis or pharmacologic methods to reverse immune dysregulation are ongoing. Therapeutic results in patients with renal cell carcinoma remain limited, and investigational approaches are warranted. PMID:10378218

    2014-03-01

    Although rare, severe hidradenitis suppurativa (HS) of the anal, perianal, gluteal, thigh, and groin regions can evolve into squamous cell carcinoma (SCC). This usually does not occur until the HS has been present for more than 20 years. Malignant degeneration of HS in the axilla has not been reported. SCC has developed in dissecting cellulitis, acne conglobata, and pilonidal cysts (other members of the follicular tetrad). Whereas the male to female ratio of HS is 1:3, SCC in HS has a male to female ration of 5:1. The reasons behind malignant degeneration in HS are complex and might differ from the malignant degeneration causing Marjolin ulcers. It likely involves the presence of human papilloma virus (HPV) in affected areas (a rarity in the axilla), and impaired defensins, which combat HPV, in the skin of Hurley Stage III HS. In familial HS, the odds of developing SCC are likely greater because of independent loss-of-function mutations in the γ-secretase multiprotein complex, which regulates the Notch signaling pathway. Compromise of the Notch signaling pathway can undermine immune function and increase the risk of neoplastic development. Coincident SCC with use of tumor necrosis factor α blockers has been reported. I report a patient with long standing Hurley Stage III, familial HS, wwho developed metastatic SCC after 3 courses of infliximab and expired 11 months after the infliximab was started. A 47-year-old male presented with progressive HS since early adulthood. His stage III hidradenitis suppurativa (HS) involved his groin, legs buttocks, and perineal areas. Interestingly, his HS was familial; one daughter also suffered from HS. A pilonidal cyst had been excised in the past. He suffered from hypertension for which he took ramipril, 2.5 mg per day. He did not admit to smoking. He had undergone numerous surgeries and courses of clindamycin with rifampin and clindamycin with minocycline. He used pregablin among other stronger medications for pain control. He

    Full Text Available Basal cell carcinoma (BCC remains the most common form of nonmelanoma skin cancer (NMSC in Caucasians, with perhaps as many as 2 million new cases expected to occur in the United States in 2010. Many treatment options, including surgical interventions and nonsurgical alternatives, have been utilized to treat BCC. In this paper, two non-surgical options, imiquimod therapy and photodynamic therapy (PDT, will be discussed. Both modalities have demonstrated acceptable disease control rates, cosmetically superior outcomes, and short-term cost-effectiveness. Further studies evaluating long-term cure rates and long-term cost effectiveness of imiquimod therapy and PDT are needed.

    Full Text Available OBJECTIVE: Non-small cell lung carcinoma (NSCLC is the most common type of lung cancer. Most patients are diagnosed at an advanced stage, palliative chemotherapy therefore being the only treatment option. This study was aimed at evaluating the health-related quality of life (HRQoL of advanced-stage NSCLC patients receiving palliative chemotherapy with carboplatin and paclitaxel. METHODS: This was a multiple case study of advanced-stage NSCLC outpatients receiving chemotherapy at a public hospital in Rio de Janeiro, Brazil. The European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire was used in conjunction with its supplemental lung cancer-specific module in order to assess HRQoL. RESULTS: Physical and cognitive functioning scale scores differed significantly among chemotherapy cycles, indicating improved and worsened HRQoL, respectively. The differences regarding the scores for pain, loss of appetite, chest pain, and arm/shoulder pain indicated improved HRQoL. CONCLUSIONS: Chemotherapy was found to improve certain aspects of HRQoL in patients with advanced-stage NSCLC.

    Small cell lung carcinoma (SCLC) commonly metastasizes to distant organs. However, metastasis to the pancreas is not a common event. Moreover, obstructive jaundice as a first clinical presentation of SCLC is extremely unusual. This case reports a 51-year-old male with SCLC, manifesting with obstructive jaundice as the initial clinical presentation. Endoscopic retrograde cholangiopancreatograghy (ERCP) and abdominal computed tomography (CT) scan showed a mass at the head of the pancreas. The patient underwent pancreatoduodenectomy (Whipple procedure). Histopathology revealed a chromogranin- A-positive poorly-differentiated neuroendocrine carcinoma of the pancreas. No imaging study of the lung was performed before surgery. A few months later, a follow-up CT revealed unilateral lung nodules with ipsilateral hilar nodes. A lung biopsy was done and histopathology reported a TTF- 1-positive, chromogranin A-positive, small cell carcinoma of the lung. On review, the pancreatic tumour was also TTF-1-positive. He was then treated with combination chemotherapy (cisplatin, etoposide). These findings highlight that presentation of a mass at the head of pancreas could be a manifestation of a metastatic tumour from elsewhere such as the lung, and thorough investigations should be performed before metastases can be ruled out.

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

    2012-01-01

    Renal cell carcinoma is the most common type of renal malignancy and it originates from the renal tubular epithelium. Due to the diversity in the histopathological and molecular characteristics, it is typically subclassified into five different categories. Papillary renal cell carcinoma is one subclassification and it includes two variants: sporadic and hereditary. Although the hereditary form comprises a smaller number of cases of papillary renal cell carcinoma, an understanding of the molec...

    Full Text Available Spindle cell carcinoma (SpCC is a unique variant of squamous cell carcinoma (SCC. SpCC confined to the nasal cavity is extremely rare, with only one case having been previously reported. We present a case report of nasal cavity SpCC and review the literature on this rare entity. A 29-year-old male presented with intermittent epistaxis from the left nasal cavity. On physical examination, the patient had an ulcerated mass in the left nasal vestibule and a biopsy showed a proliferation of spindle and epitheliod cells. The patient underwent wide local excision of the mass via a lateral alotomy approach and reconstruction with a composite conchal bowl skin and cartilage graft. Histologically, the mass had dyplastic squamous epithelium and spindle-shaped cells admixed with epitheliod cells. Immunohistochemistry was only positive for pancytokeratin AE1/AE3 and vimentin. Six months after surgery, the patient continues to have no evidence of disease. On literature review, only one previous case of SpCC confined to the nasal cavity was identified. We present a rare case of nasal cavity SpCC. No definite treatment protocol exists for this unique entity, but we believe that this tumor should primarily be treated with aggressive, wide local excision. Adjuvant radiation and/or chemotherapy have also been used anecdotally.

    Full Text Available Abstract Background The SINS trial (Controlled Clinical Trials ISRCTN48755084; Eudract No. 2004-004506-24 is a randomised controlled trial evaluating long term success of excisional surgery vs. imiquimod 5% cream for low risk nodular and superficial basal cell carcinoma (BCC. The trial included a discrete choice experiment questionnaire to explore patient preferences of a cream versus surgery for the treatment of their skin cancer. Methods The self-completed questionnaire was administered at baseline to 183 participants, measuring patients’ strength of preferences when choosing either alternative ‘surgery’ or ‘imiquimod cream’ instead of a fixed ‘current situation’ option (of surgical excision as standard practice in UK. The treatments were described according to: cost, chance of complete clearance, side effects and appearance. Participants had to choose between various scenarios. Analysis was performed using a mixed logit model, which took into account the impact of previous BCC treatment and sample preference variability. Results The analysis showed that respondents preferred ‘imiquimod cream’ to their ‘current situation’ or ‘surgery’, regardless of previous experience of BCC symptoms and treatment. Respondents were more likely to be worried about their cosmetic outcomes and side effects they might experience over and above their chance of clearance and cost. Those with no experience of surgery (compared with experience valued more the choice of ‘imiquimod cream’ (£1013 vs £781. All treatment characteristics were significant determinants of treatment choice, and there was significant variability in the population preferences for all of them. Conclusions Patients with BCC valued more ‘imiquimod cream’ than alternative ‘surgery’ options, and all treatment characteristics were important for their choice of care. Understanding how people with a BCC value alternative interventions may better inform the

  3. BRCA1 mRNA expression as a predictive and prognostic marker in advanced esophageal squamous cell carcinoma treated with cisplatin- or docetaxel-based chemotherapy/chemoradiotherapy.

    Directory of Open Access Journals (Sweden)

    Yong Gao

    Full Text Available BACKGROUND: The molecular backgrounds that determine therapeutic effectiveness in esophageal cancer remain largely unknown. Breast cancer susceptibility gene 1 (BRCA1 expression has been found to switch the response to cisplatin- or paclitaxel-based chemotherapy. It remains unclear how variations in BRCA1 expression influence clinical outcomes in esophageal cancer. PATIENTS AND METHODS: Quantitative real-time polymerase chain reaction (qPCR was performed to examine BRCA1 mRNA expressions in paraffin-embedded specimens from 144 patients with advanced or metastatic esophageal squamous cell carcinoma who received cisplatin- or docetaxel-based first-line treatments. RESULTS: Low BRCA1 mRNA expression correlated with increased response rate (RR; P = 0.025 and 0.017, respectively and median overall survival (mOS; P = 0.002 and P<0.001, respectively in cisplatin-based chemotherapy or chemoradiotherapy group and also correlated with decreased RR (P = 0.017 and 0.024, respectively and mOS (both P<0.001 in docetaxel-based chemotherapy or chemoradiotherapy group. Multivariate analysis revealed that low BRCA1 expression was an independent prognostic factor in cisplatin-based chemotherapy (HR 0.29; 95%CI 0.12-0.71; P = 0.007 or chemoradiotherapy (HR 0.12; 95%CI 0.04-0.37; P<0.001 group and higher risk for mortality in docetaxel-based chemotherapy (HR 5.02; 95%CI 2.05-12.28; P<0.001 or chemoradiotherapy (HR 7.02; 95%CI 2.37-27.77; P<0.001 group. CONCLUSIONS: BRCA1 mRNA expression could be used as a predictive and prognostic marker in esophageal cancer who underwent first-line cisplatin- or docetaxel-based treatments.

  7. Perineural Infiltration of Cutaneous Squamous Cell Carcinoma and Basal Cell Carcinoma Without Clinical Features

    International Nuclear Information System (INIS)

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

    2016-04-01

    Small cell carcinoma of the gall bladder (SCCGB) is a rare condition, with only 53 prior cases reported in the world literature when our case was first diagnosed. Our patient was found to have limited stage disease and was treated with sequential laparoscopic cholecystectomy, etoposide/carboplatin chemotherapy followed by consolidating loco-regional radiation therapy. She is alive and well without evidence of disease more than 132 months since diagnosis. We describe here our experience in the diagnosis, staging workup, treatment, and surveillance of a case of SCCGB and review the published literature. Treated aggressively with currently available methods, patients with limited stage SCCGB can have an excellent prognosis. The authors' intent is to provide a reasonable plan of treatment for other physicians facing such an unusual patient. PMID:27197345

  10. Clear cell carcinoma of the uterine corpus following irradiation therapy for squamous cell carcinoma of the cervix

    International Nuclear Information System (INIS)

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

    Full Text Available We previously published our and Johns Hopkins data titled: "Platinum-based therapy in adenosquamous pancreatic cancer: experience at two institutions” [1]. We will here like to submit a related case report as a letter to the editor to JOP in reference to the above paper. Squamous cell carcinoma of the pancreas has various reported incidence rates, ranging from 0.5% to as high as 5% of pancreatic ductal carcinomas [2, 3]. Of the 1300 cases of pancreatic cancers observed at autopsy in a survey in Japan in 1992, 0.7% were squamous cell carcinoma [4]. A Mayo clinic review of very rare exocrine tumors showed an even rarer incidence of squamous cell carcinoma when compared to acinar and small cell carcinoma of the pancreas [5]. This discrepancy in the reported incidence rates related to the fact that some of the cases represent adenosquamous carcinoma rather than pure squamous cell carcinoma of pancreas. In an analysis of 25 patients, mean age at diagnosis of pancreatic squamous cell carcinoma was 62 years (range: 33–80 years and there was no gender difference [6]. There is no study about the molecular profile of squamous carcinoma of the pancreas. There are no retrospective or prospective studies about the best therapy for these tumors

  12. Early assessment by FDG-PET/CT of patients with advanced renal cell carcinoma treated with tyrosine kinase inhibitors is predictive of disease course

    International Nuclear Information System (INIS)

    We reported previously that 18F-2-fluoro-2-deoxyglucose positron emission tomography/ computed tomography (FDG PET/CT) had potential for evaluating early response to treatment by tyrosine kinase inhibitors (TKIs) in advanced renal cell carcinoma (RCC). This time we investigated the relation of the early assessment by FDG PET/CT to long-term prognosis with an expanded number of patients and period of observation. Patients for whom TKI treatment for advanced RCC was planned were enrolled. FDG PET/CT was performed before TKI treatment and after one month of TKI treatment. The relations of the FDGPET/CT assessment to progression free survival (PFS) and overall survival (OS) were investigated. Thirty-five patients were enrolled (sunitinib 19 cases, sorafenib 16 cases). The patients with RCC showing high SUVmax in pretreatment FDG PET/CT demonstrated short PFS (P =0.024, hazard ratio 1.137, 95% CI 1.017-1.271) and short OS (P =0.004, hazard ratio 1.210 95% CI 1.062-1.379). Thirty patients (sunitinib 16 cases, sorafenib 14 cases) were evaluated again after 1 month. The PFS of the patients whose SUVmax decreased<20% was shorter than that of the patients whose SUVmax decreased<20% (P = 0.027, hazard ratio 3.043, 95% CI 1.134-8.167). The PFS of patients whose tumor diameter sum increased was shorter than that of the patient with tumors whose diameter sum did not (P =0.006, hazard ratio 4.555, 95% CI 1.543-13.448). The patients were classified into three response groups: good responder (diameter sum did not increase, and SUVmax decreased ≥ 20%), intermediate responder (diameter sum did not increase, and SUVmax decreased<20%), and poor responder (diameter sum increased, or one or more new lesions appeared). The median PFS of good, intermediate, and poor responders were 458 ± 146 days, 131 ± 9 days, and 88 ± 26 days (good vs. intermediate P = 0.0366, intermediate vs. poor P = 0.0097, log-rank test). Additionally the mean OSs were 999 ± 70 days, 469 ± 34 days, and 374

  3. Impact of Prophylactic Cranial Irradiation Timing on Brain Relapse Rates in Patients With Stage IIIB Non–Small-Cell Lung Carcinoma Treated With Two Different Chemoradiotherapy Regimens

    International Nuclear Information System (INIS)

    Purpose: To retrospectively assess the influence of prophylactic cranial irradiation (PCI) timing on brain relapse rates in patients treated with two different chemoradiotherapy (CRT) regimens for Stage IIIB non–small-cell lung cancer (NSCLC). Methods and Materials: A cohort of 134 patients, with Stage IIIB NSCLC in recursive partitioning analysis Group 1, was treated with PCI (30 Gy at 2 Gy/fr) following one of two CRT regimens. Regimen 1 (n = 58) consisted of three cycles of induction chemotherapy (ICT) followed by concurrent CRT (C-CRT). Regimen 2 (n = 76) consisted of immediate C-CRT during thoracic radiotherapy. Results: At a median follow-up of 27.6 months (range, 7.2–40.4), 65 patients were alive. Median, progression-free, and brain metastasis-free survival (BMFS) times for the whole study cohort were 23.4, 15.4, and 23.0 months, respectively. Median survival time and the 3-year survival rate for regimens 1 and 2 were 19.3 vs. 26.1 months (p = 0.001) and 14.4% vs. 34.4% (p < .001), respectively. Median time from the initiation of primary treatment to PCI was 123.2 (range, 97–161) and 63.4 (range, 55–74) days for regimens 1 and 2, respectively (p < 0.001). Overall, 11 (8.2%) patients developed brain metastasis (BM) during the follow-up period: 8 (13.8%) in regimen 1 and 3 (3.9%) in regimen 2 (p = 0.03). Only 3 (2.2%) patients developed BM at the site of first failure, and for 2 of them, it was also the sole site of recurrence. Median BMFS for regimens 1 and 2 were 17.4 (13.5–21.3) vs. 26.0 (22.9–29.1 months), respectively (p < 0.001). Conclusion: These results suggest that in Stage IIIB NSCLC patients treated with PCI, lower BM incidence and longer survival rates result from immediate C-CRT rather than ITC-first regimens. This indicates the benefit of earlier PCI use without delay because of induction protocols.

    Full Text Available Radiofrequency ablation (RFA recently has been applied to benign thyroid nodules, mainly for the cosmetic reasons, and limited cases of local recurrences or focal distant metastases of well-differentiated thyroid cancer, in the high-risk reoperative condition or for the palliative purpose. But no report has been made on the RFA for primary thyroid cancer to date. We report on a patient with primary papillary carcinoma of thyroid gland who had undergone RFA before the cytological diagnosis of malignancy, later referred and treated with robotic surgery successfully. We can learn the following lessons from our case; (1 the RFA for operable primary thyroid malignancy should be avoided, because of the possibility of remnant viable cancer and undetectable nodal metastasis, and (2 robotic or endoscopic thyroid surgery may be a feasible operative method for benign or malignant thyroid nodules previously treated with RFA.

    Purpose: This randomized phase III trial investigated the potential benefit of concurrent re-irradiation, fluorouracil and hydroxyurea versus methotrexate for patients treated with palliative intent for recurrent or second primary head and neck squamous cell carcinoma (HNSCC) in previously irradiated area. Patients and methods: Patients with recurrent HNSCC or a second primary not amenable to curative-intent treatment were randomized to the R-RT arm (concurrent re-irradiation, fluorouracil and hydroxyurea) or to the Ch-T arm (methotrexate). The primary endpoint was overall survival (OS). Due to a very slow accrual, the trial was closed after inclusion of 57 patients. Results: Fifty-seven patients were included. All patients died in the two arms with a maximal follow-up of 5 years. Although four complete responses were achieved in R-RT arm, (none in Ch-T arm) re-irradiation did not improve OS compared with methotrexate (23% versus 22% at 1 year, NS). Sixteen patients experienced clinical grade ≥3 late toxicities (>6 months), 11 in R-RT arm and five in Ch-T arm. Conclusions: Premature discontinuation of the trial did not allow us to draw firm conclusions. However, there was no suggestion that concurrent re-irradiation, fluorouracil and hydroxyurea improved OS compared to methotrexate alone in patients treated with palliative intent for a recurrent or second primary HNSCC.

    Full Text Available Tumors of nail unit may be benign or malign. Different histological variants of subungual tumours have been reported. Subungual squamous cell carcinoma is rare, and the disease is often misdiagnosed as a benign condition, therefore it is difficult to estimate the real incidence of this disease. We hereby present a case of subungual squamous cell carcinoma that has previously been treated as leading to a delay in diagnosis and treatment. For this reason, the nail unit changes should be examined carefully and the diagnosis should be done with the histopathological examinations. Proper treatment should be planned according to the histopathological diagnosis.

    International Nuclear Information System (INIS)

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

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

  20. Impact of adverse events, treatment modifications, and dose intensity on survival among patients with advanced renal cell carcinoma treated with first-line sunitinib: a medical chart review across ten centers in five European countries

    International Nuclear Information System (INIS)

    Angiogenesis inhibitors have become standard of care for advanced and/or metastatic renal cell carcinoma (RCC), but data on the impact of adverse events (AEs) and treatment modifications associated with these agents are limited. Medical records were abstracted at 10 tertiary oncology centers in Europe for 291 patients ≥18 years old treated with sunitinib as first-line treatment for advanced RCC (no prior systemic treatment for advanced disease). Logistic regression models were estimated to compare dose intensity among patients who did and did not experience AEs during the landmark periods (18, 24, and 30 weeks). Cox proportional hazard models were used to explore the possible relationship of low-dose intensity (defined using thresholds of 0.7, 0.8, and 0.9) and treatment modifications during the landmark periods to survival. 64.4% to 67.9% of patients treated with sunitinib reported at least one AE of any grade, and approximately 10% of patients experienced at least one severe (grade 3 or 4) AE. Patients reporting severe AEs were statistically significantly more likely to have dose intensities below either 0.8 or 0.9. Dose intensity below 0.7 and dose discontinuation during all landmark periods were statistically significantly associated with shorter survival time. This study of advanced RCC patients treated with sunitinib in Europe found a significant relationship between AEs and dose intensity. It also found correlations between dose intensity and shorter survival, and between dose discontinuation and shorter survival. These results confirm the importance of tolerable treatment and maintaining dose intensity

    Twenty-two patients with squamous carcinoma of the nasal vestibule were treated at the University of Florida Division of Radiation Therapy with curative intent. Fifteen lesions were de novo and seven recurrent after surgery. By AJCC classification, 7 lesions were Tx or T1, 2 were T2, 2 were T3, and 11 were T4. Management of the primary tumor and regional lymphatic drainage was highly individualized. Local control was achieved in 19 out of 22 lesions. The ultimate regional lymph node control rate was 22 out of 22, although two patients required radical neck dissection after development of lymph node disease in untreated regional lymphatics. Two patients have died of cancer and three of intercurrent disease. Cosmetic results are generally excellent but may be compromised by previous surgery in recurrent lesions or tumor destruction of normal tissues in advanced lesions. Complications of treatment are minimal.

    International Nuclear Information System (INIS)

    Purpose: To describe the outcome of patients with nonmetastatic nasopharyngeal carcinoma (NPC) treated with conventional radiotherapy at a single institution. Methods and materials: From 1990 to 1999, 171 consecutive patients with NPC were treated with conventional (two-dimensional) radiotherapy. Tumor histology was undifferentiated in 82% of cases. Tumor-node-metastasis Stage (American Joint Committee on Cancer/International Union Against Cancer 1997 system) was I in 6%, II in 36%, III in 22%, and IV in 36% of patients. Mean total radiation dose was 68.4 Gy. Chemotherapy was given to 62% of the patients. The median follow-up for surviving patients was 6.3 years (range, 3.1-13.1 years). Results: The 5-year overall survival, disease-specific survival, and disease-free survival rates were 72%, 74%, and 62%, respectively. The 5-year local, regional, and distant control rates were 84%, 80%, and 83% respectively. Late effects of radiotherapy were prospectively recorded in 100 patients surviving without relapse; 44% of these patients had Grade 3 xerostomia, 33% had Grade 3 dental damage, and 11% had Grade 3 hearing loss. Conclusions: This analysis shows an improved outcome for patients treated from 1990 to 1999 compared with earlier retrospective series, despite the use of two-dimensional radiotherapy. Late toxicity, however, was substantial with conventional radiotherapy

  7. Small cell carcinoma of the urinary bladder

    International Nuclear Information System (INIS)

    Small cell carcinoma of the urinary bladder (SCCUB) is an extremely rare tumor that exhibits aggressive behavior and accounts for approximately less than 1% of all primary bladder tumors. Small cell carcinoma generally occurs in the lung, accounting for 25% of all pulmonary malignancies. SCCUB exhibits a similar microscopic and immunohistochemical appearance to that of small cell carcinoma of the lung. There is no consensus about the standard therapy, owing to its rarity. Surgical resection seems to be the mainstay of treatment for patients with limited stage, together with neoadjuvant or adjuvant platinum-based chemotherapy. Radiation therapy has same small effect for palliative purposes, as well as being an alternative to radical cystectomy. Patients with advanced stage, although given platinum-based chemotherapy, have a poor prognosis. We herein review epidemiology, clinical presentation, diagnosis, pathological features, and current management of small cell carcinoma of the urinary bladder. (author)

    From 1969 to 1978, 345 patients with endometrial carcinoma were treated at the Medical College of Virginia. Twenty-three of these were clear cell carcinoma (6.6%). Previous reports indicate a poor prognosis with this histological entity. In this series no differences were noticed between clear cell carcinoma and classical adenocarcinoma with regard to variables such as age, race, stage at presentation or response to treatment. Clear cell carcinoma is a distinct histological entity and does not appear to be different than classical adenocarcinoma in its behavior and response to therapy. It is recommended that these tumors be managed by a combination of surgery and radiotherapy

    The objective of this study was to compare the prognostic utility of the 2-[18F] fluoro-2-deoxy-D-glucose (FDG) maximum standardized uptake value (SUVmax), primary gross tumor volume (GTV), and FDG metabolic tumor volume (MTV) for disease control and survival in patients with head and neck squamous cell carcinoma (HNSCC) undergoing intensity-modulated radiotherapy (IMRT). Between 2007 and 2011, 41 HNSCC patients who underwent a staging positron emission tomography with computed tomography and definitive IMRT were identified. Local (LC), nodal (NC), distant (DC), and overall (OC) control, overall survival (OS), and disease-free survival (DFS) were assessed using the Kaplan-Meier product-limit method. With a median follow-up of 24.2 months (range 2.7-56.3 months) local, nodal, and distant recurrences were recorded in 10, 5, and 7 patients, respectively. The median SUVmax, GTV, and MTV were 15.8, 22.2 cc, and 7.2 cc, respectively. SUVmax did not correlate with LC (p=0.229) and OS (p=0.661) when analyzed by median threshold. Patients with smaller GTVs (max, with larger tumor volumes correlating with inferior local control and overall survival in HNSCC patients treated with definitive IMRT. (author)

    Full Text Available Circulating tumor cells (CTCs are those cells present in the blood and have antigenic and/or genetic characteristics of a specific tumor type. CTCs can be detected in the peripheral blood of cancer patients. Various techniques are available for detection of CTCs, which provide evidence for future metastasis. CTCs may provide new insight into the biology of cancer and process of metastasis in oral squamous cell carcinoma (OSCC. The detection of CTCs may represent a new diagnostic tool for predicting the occurrence of metastatic disease in OSCC and endow with the treatment strategies to efficiently treat and prevent cancer metastasis. This review gives an insight into the significance of CTCs and different techniques for detection of CTCs.

Case Report: A 58-year-old woman who presented with jaundice and preoperative endoscopic and radiological procedures could not show whether the tumour was carcinoma planoepitheliale. The clinical presentation, biochemical, radiographic and endoscopic investigation pronounced advanced pancreatic adenocarcinoma. Results: We performed pancreaticoduodenectomy with curative intention. Histological examination revealed: planoepitheliale cell carcinoma of the ampullo-pancreatic unit. Conclusions: In conclusion, preoperative endoscopic and radiological evaluations can all prove insufficient to distinguish between benign and malignant tumour. Thus, for malignant tumours surgeons may be forced to perform extensive surgery. (authors)

    Full Text Available Abstract Background Novel therapies are necessary to improve outcomes for patients with squamous cell carcinomas (SCC of the head and neck. Historically, vaccinia virus was administered widely to humans as a vaccine and led to the eradication of smallpox. We examined the therapeutic effects of an attenuated, replication-competent vaccinia virus (GLV-1h68 as an oncolytic agent against a panel of six human head and neck SCC cell lines. Results All six cell lines supported viral transgene expression (β-galactosidase, green fluorescent protein, and luciferase as early as 6 hours after viral exposure. Efficient transgene expression and viral replication (>150-fold titer increase over 72 hrs were observed in four of the cell lines. At a multiplicity of infection (MOI of 1, GLV-1h68 was highly cytotoxic to the four cell lines, resulting in ≥ 90% cytotoxicity over 6 days, and the remaining two cell lines exhibited >45% cytotoxicity. Even at a very low MOI of 0.01, three cell lines still demonstrated >60% cell death over 6 days. A single injection of GLV-1h68 (5 × 106 pfu intratumorally into MSKQLL2 xenografts in mice exhibited localized intratumoral luciferase activity peaking at days 2–4, with gradual resolution over 10 days and no evidence of spread to normal organs. Treated animals exhibited near-complete tumor regression over a 24-day period without any observed toxicity, while control animals demonstrated rapid tumor progression. Conclusion These results demonstrate significant oncolytic efficacy by an attenuated vaccinia virus for infecting and lysing head and neck SCC both in vitro and in vivo, and support its continued investigation in future clinical trials.

  2. Effectiveness of brachytherapy in treating carcinoma of the vulva

    International Nuclear Information System (INIS)

    Purpose: Radical radiotherapeutic management of vulvar cancer often incorporates brachytherapy as a portion of the treatment regimen. However, few studies using this modality alone to manage vulvar cancer have been published. Methods and Materials: Thirty four patients were treated with iridium-192 (192Ir) brachytherapy for vulvar cancer between 1975 and 1993 at Centre Alexis Vautrin. Twenty-one patients were treated at first presentation when surgery was contraindicated or declined. Of these patients, 12 had International Federation of Gynecology and Obstetrics Classification Stage III or IV disease, 8 were Stage II, 1 was Stage I, and 1 was Stage 0. Thirteen patients were treated for recurrent disease. Paris system rules for implantation and dose prescription were followed. The median reference dose was 60 Gy (range 53 to 88 Gy). At the time of analysis, 10 of 34 patients were alive. Median follow-up in these 10 patients was 31 months (range: 21 months to 107 months). Fourteen of the 24 deaths were from causes other than vulvar cancer. Results: Kaplan-Meier actuarial 5-year local control was 47% (95% confidence interval (CI) = 23 to 73%) and 5-year actuarial loco-regional control was 45% (95% CI = 21 to 70%). Kaplan-Meier actuarial 5-year disease-specific survival was 56% (95% CI = 33 to 76%) and actuarial 5-year survival was 29% (95% CI = 15 to 49%). Median time to death was 14 months. Subset analysis revealed a higher actuarial 5-year local control in patients treated at first presentation than those treated for recurrence (80 vs. 19%, log rank, p = 0.04). Similarly, actuarial 5-year loco-regional control was higher in patients treated at first presentation (80 vs. 16%, log rank, p 0.01). The two groups did not differ significantly in disease-specific or overall survival. The actuarial 5-year disease specific survival of 56% is somewhat less than the expected 5-year disease-specific survival after surgery in a group having a similar proportion of early stage

    Dracaena cinnabari Balf.f. is a red resin endemic to Socotra Island, Yemen. Although there have been several reports on its therapeutic properties, information on its cytotoxicity and anticancer effects is very limited. This study utilized a bioassay-guided fractionation approach to determine the cytotoxic and apoptosis-inducing effects of D. cinnabari on human oral squamous cell carcinoma (OSCC). The cytotoxic effects of D. cinnabari crude extract were observed in a panel of OSCC cell lines and were most pronounced in H400. Only fractions DCc and DCd were active on H400 cells; subfractions DCc15 and DCd16 exhibited the greatest cytotoxicity against H400 cells and D. cinnabari inhibited cells proliferation in a time-dependent manner. This was achieved primarily via apoptosis where externalization of phospholipid phosphatidylserine was observed using DAPI/Annexin V fluorescence double staining mechanism studied through mitochondrial membrane potential assay cytochrome c enzyme-linked immunosorbent and caspases activities revealed depolarization of mitochondrial membrane potential (MMP) and significant activation of caspases 9 and 3/7, concomitant with S phase arrest. Apoptotic proteins array suggested that MMP was regulated by Bcl-2 proteins family as results demonstrated an upregulation of Bax, Bad, and Bid as well as downregulation of Bcl-2. Hence, D. cinnabari has the potential to be developed as an anticancer agent.

Human EK exists as EK1, EK2α and EK2β isoforms, encoded by two separate genes, named ek1 and ek2. EK activity is stimulated by carcinogens and oncogenes, suggesting the involvement of EK in carcinogenesis. Currently, little is known about EK transcriptional regulation by endogenous or exogenous signals, and the ek gene promoter has never been studied.In this report, we mapped the important regulatory regions in the human ek1 promoter. 5' deletion analysis and site-directed mutagenesis identified a Sp site at position (-40/-31 that was essential for the basal transcription of this gene. Treatment of HCT116 cells with trichostatin A (TSA, a histone deacetylase inhibitor, significantly upregulated the ek1 promoter activity through the Sp(-40/-31 site and increased the endogenous expression of ek1. Chromatin immunoprecipitation assay revealed that TSA increased the binding of Sp1, Sp3 and RNA polymerase II to the ek1 promoter in HCT116 cells. The effect of TSA on ek1 promoter activity was cell-line specific as TSA treatment did not affect ek1 promoter activity in HepG2 cells.In conclusion, we showed that Sp1 and Sp3 are not only essential for the basal transcription of the ek1 gene, their accessibility to the target site on the ek1 promoter is regulated by histone protein modification in a cell line dependent manner.

    Uterine clear cell carcinoma (UCC) and uterine papillary serous carcinoma (UPSC) are rare entities that differ in clinical behavior from endometrial adenocarcinoma. Compared with endometrioid adenocarcinoma, they more often metastasize early and more commonly in the upper abdomen including the omentum. Treatment programs of UCC and UPSC at different stages vary and range from no adjuvant therapy in stage Ia to a wide variety of chemotherapies and radiotherapies in more advanced stages. This study presents the outcome of 109 patients with UCC or UPSC treated according to essentially the same treatment program from May 1993 to December 2004. Most patients were treated with a simple hysterectomy with no further adjuvant treatment. In stage Ia, 2/46 patients died of their disease and amongst all the stages, 30/109 patients died of their disease. These survival outcomes are comparable to or better than those presented previously. PMID:20944161

    AIM: To study the effect of octreotide on cell proliferation and apoptosis in different hepatocellular carcinoma (HCC) cells and hepatocytes. METHODS: The proliferation of HCC cells (HepG2, SMMC-7721) and hepatocytes (L-02) was determined by MTT assay. Apoptosis was detected either by fluorescent staining, transmission electron microscopy or flow cytometry. The content of AFP in the supernatant of cultured HCC cells was determined by electrochemiluminescence immunoassay. The expression of SSTR subtypes was identified by RT-PCR.RESULTS: The proliferation of HCC cells and L-02 cells was inhibited significantly by octreotide (0.25, 0.5, 1.0,2.0 and 4.0 mg/L). However, the apoptosis of HCC cells markedly increased in a concentration-dependent manner.Both the apoptosis index and the percentage of apoptotic cells in L-02 cells were significantly lower than those of HepG2 and SMMC-7721 cells. The content of AFP in the supematant of cultured HepG2 cells treated with octreotide was also statistically reduced. Furthermore, SSTR2 and SSTR4 were positive in both the hepatocellular carcinoma cells and in the L-02 cells. SSTR3 was only expressed in the two heptatocellular carcinoma cells, and SSTR5 was found in the SMMC-7721 cells. No SSTR1 was detected either in HCC cells or L-02 cells. CONCLUSIONS:Apoptosis induction is a major mechanism of octreotide inhibition on hepatocellular cells. SSTR3 is expressed in the HCC cells, but not in the L-02 cells, which suggests a molecular basis for the HCC-selective effects of octreotide.

    Merkel cell carcinoma (MCC) in the eyelid and periocular region can be treated surgically, in most cases, with preservation of the eye and reasonable visual function. Adjuvant radiation therapy, sentinel lymph node biopsy, and chemotherapy should be considered for MCC of the eyelid and periocular region, especially for larger tumors that are T2b or more advanced and lesions that present with regional nodal or distant metastasis.

    Renal cell carcinoma is often characterized by the presence of metachronous metastases in unusual sites. The presence of isolated metastases is treated with surgical excision with good anticipated results. On the other hand, systemic chemotherapy is administered in the context of metastatic spread, usually sunitib or sorafenib. In such cases, however, the presence of symptomatic foci calls for minimal intervention. We present a case of a 77-year-old patient who presented with obstructive jaun...

    This is an analysis of 34 patients with carcinoma of the cervical esophagus treated with radiation therapy with curative intent at the University of Florida between September 1966 and May 1985. All patients have a minimum 2-year follow-up and 28 (82%) have at least 5 years of follow-up. Patients were staged according to the recommendations of the AJCC. Patients who died within 2 years of treatment with the primary site continuously disease-free were excluded from the local control analysis; all patients were included in the analysis of complications and survival. Irradiation resulted in control of the primary lesion in 1 of 2 patients who presented with T1 lesions, in 4 of the 12 patients with T2 lesions, and 3 of 17 patients who presented with T3 lesions. One patient with a T3 lesion that recurred locally was successfully salvaged by an operation. The 5-year absolute survival rates by stage were as follows: no patients with stage I lesions survived; of 11 stage II patients, one survived; and of 16 stage III patients, three survived. Interestingly, all four of the 5-year survivors were women.

    Full Text Available Pelvic squamous cell carcinoma of unknown primary origin has been described in several case reports of female patients. However, there have been no published reports describing male patients with pelvic squamous cell cancer of unknown primary origin. Our case describes a 52-year-old man who presented with right buttock pain, rectal urgency, and constipation. His physical examination demonstrated tenderness to palpation around his gluteal folds. Computed tomography scan of his abdomen and pelvis demonstrated a large mass in his retroperitoneum. The mass was determined to be squamous cell carcinoma of unknown primary origin. Additionally, the patient had small nodules in his right lower lung lobe and right hepatic lobe. The patient was treated with concomitant chemoradiation, including cisplatin and intensity-modulated radiation therapy, followed by carboplatin and paclitaxel. The patient achieved partial remission, in which he remained one year after his presentation. Our case is consistent with the literature which suggests that squamous cell carcinoma of unknown primary origin occurring outside of the head and neck region may have a more favorable prognosis than other carcinomas of unknown primary origin. Further studies are necessary to determine the most appropriate work-up, diagnosis, and optimal treatment strategies.

    Full Text Available PURPOSE: The determination of prognosis in patients with renal cell carcinoma (RCC is based, classically, on stage and histopathological aspects. The metastatic disease develops in one third of patients after surgery, even in localized tumors. There are few options for treating those patients, and even the new target designed drugs have shown low rates of success in controlling disease progression. Few studies used high throughput genomic analysis in renal cell carcinoma for determination of prognosis. This study is focused on the identification of gene expression signatures in tissues of low-risk, high-risk and metastatic RCC clear cell type (RCC-CCT. MATERIALS AND METHODS: We analyzed the expression of approximately 55,000 distinct transcripts using the Whole Genome microarray platform hybridized with RNA extracted from 19 patients submitted to surgery to treat RCC-CCT with different clinical outcomes. They were divided into three groups (1 low risk, characterized by pT1, Fuhrman grade 1 or 2, no microvascular invasion RCC; (2 high risk, pT2-3, Fuhrman grade 3 or 4 with, necrosis and microvascular invasion present and (3 metastatic RCC-CCT. Normal renal tissue was used as control. RESULTS: After comparison of differentially expressed genes among low-risk, high-risk and metastatic groups, we identified a group of common genes characterizing metastatic disease. Among them Interleukin-8 and Heat shock protein 70 were over-expressed in metastasis and validated by real-time polymerase chain reaction. CONCLUSION: These findings can be used as a starting point to generate molecular markers of RCC-CCT as well as a target for the development of innovative therapies.

    Full Text Available O carcinoma basocelular é a neoplasia maligna mais comum em humanos e sua incidência vem aumentando nas últimas décadas. Sua grande frequência gera significativo ônus ao sistema de saúde, configurando problema de saúde pública. Apesar das baixas taxas de mortalidade e de rara ocorrência de metástases, o tumor pode apresentar comportamento invasivo local e recidivas após o tratamento, provocando importante morbidade. Exposição à radiação ultravioleta representa o principal fator de risco ambiental associado a sua gênese. Entretanto, descrevem-se outros elementos de risco: fotótipos claros, idade avançada, história familiar de carcinomas de pele, olhos e cabelos claros, sardas na infância e imunossupressão, além de aspectos comportamentais, como exercício profissional exposto ao sol, atividade rural e queimaduras solares na juventude. Entre 30% e 75% dos casos esporádicos estão associados à mutação do gene patched hedgehog, mas outras alterações genéticas são ainda descritas. A neoplasia é comumente encontrada concomitantemente com lesões cutâneas relacionadas à exposição solar crônica, tais como: queratoses actínicas, lentigos solares e telangiectasias faciais. A prevenção do carcinoma basocelular se baseia no conhecimento de fatores de risco, no diagnóstico e tratamento precoces e na adoção de medidas específicas, principalmente, nas populações susceptíveis.

    Laryngeal spindle cell carcinoma (SpCC) is an uncommon subtype of squamous cell carcinoma which represents 0.5% of all laryngeal squamous cell carcinomas. It is a biphasic tumor consisting of the combination of a malignant mesenchymal spindle cell component and a squamous cell component that includes dysplasia, carcinoma in situ, or invasive carcinoma. Although it has aggressive biological features, the probability of making a diagnosis in the early stages is high as it often leads to obstructive symptoms in the early period. Due to its low incidence, there is no clear consensus on prognostic factors and optimal treatment strategies yet. In this paper, a 60-year-old laryngeal SpCC case that was effectively treated with wide local excision followed by adjuvant radiotherapy was presented with the literature. PMID:26788392

    Primary squamous cell colorectal carcinomas are uncommon, and their characteristics are not well known. They seem to occur most commonly in the fifth decade of life with a slight predominance for men. The most commonly reported anatomic locations are the rectum and the proximal colon. Clinical features and common diagnostic methods do not easily differentiate squamous cell colorectal carcinomas from adenocarcinomas. Because of their extremely rare occurrence, it is difficult to study their natural course, clinical behavior, and response to therapy. This report presents the case of a pure squamous cell colorectal cancer and provides a brief review of the literature, which includes 60 previously published cases. The case of a patient with T3N2M0 primary squamous cell carcinoma of the rectosigmoid colon, which was initially treated with abdominoperineal resection followed by adjuvant chemotherapy and radiation, is presented. During the follow-up, an elevated squamous cell carcinoma antigen (SCC Ag) level led to restaging computed tomography scans, which confirmed recurrent metastatic disease in the liver. Response to chemotherapy with a decrease in tumor size correlated with a decrease in the serum SCC Ag level. Although SCC Ag has been used as a tumor marker for squamous cell cancers of the lung, head and neck, uterine cervix, and esophagus, this is the first reported case of a squamous cell colon carcinoma presenting with an elevated SCC Ag at the time of recurrence. In addition, this patient showed an objective partial response to combination chemotherapy, with a decrease in the serum level of this tumor marker. PMID:12445380

    Full Text Available Abstract Nevoid basal cell carcinoma syndrome (NBCCS, also known as Gorlin syndrome, is a hereditary condition characterized by a wide range of developmental abnormalities and a predisposition to neoplasms. The estimated prevalence varies from 1/57,000 to 1/256,000, with a male-to-female ratio of 1:1. Main clinical manifestations include multiple basal cell carcinomas (BCCs, odontogenic keratocysts of the jaws, hyperkeratosis of palms and soles, skeletal abnormalities, intracranial ectopic calcifications, and facial dysmorphism (macrocephaly, cleft lip/palate and severe eye anomalies. Intellectual deficit is present in up to 5% of cases. BCCs (varying clinically from flesh-colored papules to ulcerating plaques and in diameter from 1 to 10 mm are most commonly located on the face, back and chest. The number of BBCs varies from a few to several thousand. Recurrent jaw cysts occur in 90% of patients. Skeletal abnormalities (affecting the shape of the ribs, vertebral column bones, and the skull are frequent. Ocular, genitourinary and cardiovascular disorders may occur. About 5–10% of NBCCS patients develop the brain malignancy medulloblastoma, which may be a potential cause of early death. NBCCS is caused by mutations in the PTCH1 gene and is transmitted as an autosomal dominant trait with complete penetrance and variable expressivity. Clinical diagnosis relies on specific criteria. Gene mutation analysis confirms the diagnosis. Genetic counseling is mandatory. Antenatal diagnosis is feasible by means of ultrasound scans and analysis of DNA extracted from fetal cells (obtained by amniocentesis or chorionic villus sampling. Main differential diagnoses include Bazex syndrome, trichoepithelioma papulosum multiplex and Torre's syndrome (Muir-Torre's syndrome. Management requires a multidisciplinary approach. Keratocysts are treated by surgical removal. Surgery for BBCs is indicated when the number of lesions is limited; other treatments include laser

    Background and purpose: imatinib (Gleevec {sup registered}, Glivec {sup registered}) is an inhibitor of {alpha}-and {beta}-platelet-derived growth factor receptors and other tyrosine kinases, that are also associated with the function of growth factors. Imatinib has been approved for the treatment of chronic myelogenous leukemia and gastrointestinal stromal tumors and is under investigation for the therapy of several other malignant tumors. Since radiotherapy is an important treatment option in many tumors, combined effects of imatinib and radiation were analyzed here. Material and methods: in vitro, U87 cells (human glioblastoma), A431 cells (human epidermoid carcinoma), and HUVECs (human umbilical, venous endothelial cells) were treated with imatinib alone and in combination with radiation. Clonogenic survival and cell proliferation were determined with and without additional radiation (0-10 Gy). In vivo, U87 and A431 cells (5 x 10{sup 6}) were subcutaneously injected into hind limbs of balb c nu/u mice. Drug and radiation treatments started on day 0 when tumor volumes were approximately 400-500 mm{sup 3}. Tumors were treated with 5 x 5 Gy (U87) or 6 x 5 Gy (A431) on consecutive days from day 0. Imatinib was administered orally via the mouse diet starting on day 0 until the end of observation. Tumor growth and microvessel density (CD31 IHC) were analyzed. Results: in vitro, imatinib increased radiosensitivity of U87 and A431 tumor cells as well as HUVECs in both clonogenic and cell number/proliferation assays. The enhancement of radiosensitivity in HUVECs was comparable to that observed in the tumor cells. In vivo, the concurrent and continuous administration of imatinib increased tumor growth delay of fractionated radiotherapy in the carcinoma and the glioblastoma models at reduced microvessel densities. No apparent additional toxicity by the combination of radiation and imatinib versus monotherapies was observed in terms of weight, skin, or general behavior

    Full Text Available Renal preservation therapy has been a promising concept for the treatment of localized renal cell carcinoma (RCC for 20 years. Nowadays partial nephrectomy (PN is well accepted to treat the localized RCC and the oncological control is proved to be the same as the radical nephrectomy (RN. Under the result of well oncological control, minimal invasive method gains more popularity than the open PN, like laparoscopic partial nephrectomy (LPN and robot assisted laparoscopic partial nephrectomy (RPN. On the other hand, thermoablative therapy and cryoablation also play an important role in the renal preservation therapy to improve the patient procedural tolerance. Novel modalities, but limited to small number of patients, include high-intensity ultrasound (HIFU, radiosurgery, microwave therapy (MWT, laser interstitial thermal therapy (LITT, and pulsed cavitational ultrasound (PCU. Although initial results are encouraging, their real clinical roles are still under evaluation. On the other hand, active surveillance (AS has also been advocated by some for patients who are unfit for surgery. It is reasonable to choose the best therapeutic method among varieties of treatment modalities according to patients' age, physical status, and financial aid to maximize the treatment effect among cancer control, patient morbidity, and preservation of renal function.

  11. Clinical analysis of ear carcinoma treated in the Department of Otolaryngology, Niigata University Hospital. Focus on correlation between treatment method and prognosis

    International Nuclear Information System (INIS)

    Thirty-six patients of ear carcinoma treated in our department were clinically analyzed. Those ear carcinoma patients accounted for 3.5% of all head and neck carcinoma patients. The most common primary site was the external auditory canal (67%), followed by the middle ear (19%) and the auricle (14%). The mean age of the patients was 66 years old, and the male to female ratio was 3:2. The most common chief complaint of the external auditory canal and middle ear carcinoma was otorrhea followed by ear itching and ear ache. Of patients with external auditory canal carcinoma and middle ear carcinoma, 26% had a history of ear surgery, and 35% had a habit of ear-picking. Histopathologically, 94% of the patients were squamous cell carcinoma, and 6% were malignant melanoma. Sixty-two % of squamous cell carcinoma patients underwent surgery, and the remaining 38% had radiotherapy without surgery. Postoperative radiotherapy was added for 67% of the surgery group. Five-year survival rates of the patients with squamous cell carcinoma were 74% for external auditory canal carcinoma, 67% for auricular carcinoma, and 34% for middle ear carcinoma, respectively. The five-year survival rate of the surgery group was 82%, and that of the non-surgery group was 29%. There was a statistical significance between the two groups. No statistical significance was seen between with and without postoperative radiotherapy. In the treatment of squamous cell carcinoma in the ear, radical en bloc surgery followed by postoperative radiotherapy was considered to be an appropriate treatment strategy. (author)

    AIM: Cell adhesion molecules and their signal molecules play a very important role in carcinogenesis. The aim of this study is to elucidate the role of these molecules and the signal molecules of integrins and E-cadherins, such as (focal adhesion kinase) FAK, (integrin linked kinase)ILK, and β-catenin in hepatocellular carcinoma cell apoptosis.METHODS: We first synthesized the small molecular compound, S-(1,2-dichlorovinyl)-L-cysteine (DCVC), and identified it, by element analysis and 1H NMR. To establish the apoptosis model of the SMMC-7721 hepatocellular carcinoma cell, we treated cells with DCVC in EBSS for different concentrations or for various length times in the presence of 20 μmol/L N,N-diphenyl-p-phenylenediamine,which blocks necrotic cell death and identified this model by flow cytometry and DNA ladder. Then we studied the changes of FAK, ILK, β-catenin, and PKB in this apoptotic model by Western blot.RESULTS: We found that the loss or decrease of cell adhesion signal molecules is an important reason in apoptosis of SMMC-7721 hepatocellular carcinoma cell and the apoptosis of SMMC-7721 cell was preceded by the loss or decrease of FAK, ILK, PKB, and β-catenin or the damage of cell-matrix and cell-cell adhesion.CONCLUSION: Our results suggested that the decrease of adhesion signal molecules, FAK, ILK, PKB, and β-catenin,could induce hepatocellular carcinoma cell apoptosis.

    The traditional view that adult human liver tumors, mainly hepatocellular carcinoma (HCC), arise from mature cell types has been challenged in recent dec-ades. The results of several studies suggest that HCC can be derived from liver stem cells. There are four levels of cells in the liver stem cell lineage: hepatocytes, hepatic stem cells/oval cells, bone marrow stem cells and hepato-pancreas stem cells. However, whether HCC is resulted from the differentiation block of stem cells and, moreover, which liver stem cell lineage is the source cell of hepatocarcinogenesis remain controversial. In this review, we focus on the current status of liver stem cell research and their roles in carcinogenesis of HCC, in order to explore new approaches for stem cell therapy of HCC.

    Full Text Available : Granulomatous inflammation is a distinctive pattern of chronic inflammatory reaction characterized by microscopic aggregation of activated macrophages which often develop epithelioid appearance and multinucleate giant cells. Granulomas are encountered in limited number of infectious and some non-infectious conditions. Granulomas have been described within the stroma of malignancies like carcinomas of the breast and colon, seminoma and Hodgkin’s lymphoma, where they represent T-cell-mediated reaction of the tumor stroma to antigens expressed by the tumor. Granulomatous reaction in association with renal cell carcinoma (RCC is uncommon, with only few published reports in the literature. We describe a case of conventional (clear cell RCC associated with epithelioid cell granulomas within the tumor parenchyma.

  20. CT differentiation of renal tumor invading parenchyma and pelvis: renal cell carcinoma vs transitional cell carcinoma

    International Nuclear Information System (INIS)

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

  4. Local thermal ablation of renal cell carcinoma

    International Nuclear Information System (INIS)

    Purpose: With evolving local thermal ablation technology, the clinical application of thermal ablation has been actively investigated in the treatment for renal cell carcinoma. We review the evolution and current status of radiofrequency ablation and microwave ablation for renal cell carcinoma. Materials and methods: All articles published in English on radiofrequency ablation or microwave ablation as a treatment for renal cell carcinoma were identified with a MEDLINE® and PubMed® search from 1990 to 2010. Results: Local thermal ablation has several advantages, including keeping more normal renal units, relatively simple operation, easy tolerance, fewer complications, a shorter hospitalization and convalescence period. Long-term data has determined radiofrequency ablation is responsible for poor surgical candidates with renal cell carcinoma, however, tumor size, location and shape might affect the efficacy of radiofrequency ablation. Microwave ablation can induce large ablation volumes and yield good local tumor control. Associated complications appear to be low. Conclusions: Local ablative approaches seem to represent an attractive alternative to extirpative surgery for the treatment of small renal neoplasms in select patients. Potential developments include concepts to improve the accuracy and effectiveness of thermal ablation by improving the guiding, monitoring capabilities and detection capacity of multi-center lesions to provide at least equivalent cancer control to conventional surgery.

  6. All delays before radiotherapy risk progression of Merkel cell carcinoma

    International Nuclear Information System (INIS)

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

  7. Octreotide scintigraphy localizes somatostatin receptor-positive islet cell carcinomas

    International Nuclear Information System (INIS)

    Tyr-3-octreotide is a synthetic derivative of somatostatin and a somatostatin-receptor analogue. The iodine-123-labelled compound localizes somatostatin-receptor-positive tumours. In this paper two patients are reported in whom somatostatin receptors were demonstrated in vitro. In a 60-year-old female with an islet cell carcinoma of the pancreas, multiple liver metastases and previously uncrecognized bone metastases in the right acetabulum could be diagnosed as the reason for a persistent hypoglycaemia. In a 60-year-old male an islet cell carcinoma of the pancreas was localized with 123I-Tyr-3-octreotide. The somatostatin receptors were demonstrated in vitro and the tumour was successfully treated with somatostatin. These studies demonstrate that 123I-Tyr-3-octreotide offers the possibility of localizing somatostatin-receptor-positive tumours and their metastases. Moreover the method makes it possible to determine the receptor status of a tumour in vivo. (orig.)

  14. Higher Biologically Effective Dose of Radiotherapy Is Associated With Improved Outcomes for Locally Advanced Non–Small Cell Lung Carcinoma Treated With Chemoradiation: An Analysis of the Radiation Therapy Oncology Group

    International Nuclear Information System (INIS)

    Purpose: Patients treated with chemoradiotherapy for locally advanced non–small-cell lung carcinoma (LA-NSCLC) were analyzed for local-regional failure (LRF) and overall survival (OS) with respect to radiotherapy dose intensity. Methods and Materials: This study combined data from seven Radiation Therapy Oncology Group (RTOG) trials in which chemoradiotherapy was used for LA-NSCLC: RTOG 88-08 (chemoradiation arm only), 90-15, 91-06, 92-04, 93-09 (nonoperative arm only), 94-10, and 98-01. The radiotherapeutic biologically effective dose (BED) received by each individual patient was calculated, as was the overall treatment time-adjusted BED (tBED) using standard formulae. Heterogeneity testing was done with chi-squared statistics, and weighted pooled hazard ratio estimates were used. Cox and Fine and Gray’s proportional hazard models were used for OS and LRF, respectively, to test the associations between BED and tBED adjusted for other covariates. Results: A total of 1,356 patients were analyzed for BED (1,348 for tBED). The 2-year and 5-year OS rates were 38% and 15%, respectively. The 2-year and 5-year LRF rates were 46% and 52%, respectively. The BED (and tBED) were highly significantly associated with both OS and LRF, with or without adjustment for other covariates on multivariate analysis (p < 0.0001). A 1-Gy BED increase in radiotherapy dose intensity was statistically significantly associated with approximately 4% relative improvement in survival; this is another way of expressing the finding that the pool-adjusted hazard ratio for survival as a function of BED was 0.96. Similarly, a 1-Gy tBED increase in radiotherapy dose intensity was statistically significantly associated with approximately 3% relative improvement in local-regional control; this is another way of expressing the finding that the pool-adjusted hazard ratio as a function of tBED was 0.97. Conclusions: Higher radiotherapy dose intensity is associated with improved local-regional control

    Full Text Available Context Acinar cell carcinoma of the pancreas is a rare malignancy, accounting for 1-2% of pancreatic exocrine malignancies. This rarity makes it difficult to standardize a protocol of treatment for acinar cell carcinoma. Case report A 71-year-old male without any particular past history was referred to our institute with abdominal distention and mild liver dysfunction. Computed tomography (CT revealed a cystic lesion with a diameter of 3.5 cm, which originated from the neck of pancreas and had solid nodules inside. Several nodules were demonstrated surrounding the cystic tumor. Laparotomy and histological study demonstrated peritoneal dissemination of acinar cell carcinoma. The patient was treated with S-1 monotherapy (80 mg/m2 for four weeks with a two-week interval as one cycle. After one cycle of S-1 monotherapy, CT demonstrated remarkable shrinkage of the main tumor and disappearance of the nodules on the peritoneum. The patient underwent a radical distal pancreatectomy. The patient was then treated with 16 cycles of S-1 monotherapy after the radical pancreatectomy and remains without any recurrence of the disease two years later. Conclusion Initially inoperable acinar cell carcinoma was treated by monotherapy using S-1, resulting in curative operation and two years disease free survival post operation. S-1 might be more effective on acinar cell carcinoma, rather than gemcitabine

    Malignant germ cell tumors of the ovary are very rare and account for about 2-5% of all ovarian tumors of germ origin. Most patients are adolescent and young women, approximately two-thirds of them are under 20 years of age, occasionally in postmenopausal women. But clear cell carcinoma usually occurs in older patients (median age: 57-year old), and closely related with endometriosis. Here we report a case of a 55-year old woman with right ovarian mass that discovered by B ultrasonic. Her serum levels of human chorionic gonadotropin (hCG) and α-fetoprotein (AFP) were elevated. Pathological examination revealed the tumor to be a mixed germ cell tumor (yolk sac tumor, embryonal carcinoma and mature teratoma) with clear cell carcinoma in a background of endometriosis. Immunohistochemical staining showed SALL4 and PLAP were positive in germ cell tumor area, hCG, CD30 and OCT4 were positive in epithelial-like cells and giant synctiotrophoblastic cells, AFP, AAT, CD117 and Glyp3 were positive in yolk sac component, EMA and CK7 were positive in clear cell carcinoma, CD10 was positive in endometrial cells of endometriotic area. She was treated with surgery followed by seven courses of chemotherapy. She is well and serum levels of hCG and AFP have been decreased to normal levels. PMID:25674278

    Full Text Available Elena Verzoni, Paolo Grassi, Isabella Testa, Roberto Iacovelli, Pamela Biondani, Enrico Garanzini , Filippo De Braud, Giuseppe ProcopioDepartment of Medical Oncology 1, Fondazione IRCCS Istituto Nazionale Tumori, Milan, ItalyAbstract: Antiangiogenesis options have evolved rapidly in the last few years, with an increasing number of agents currently approved by the US Food and Drug Administration and European Medicines Agency. Angiogenesis inhibitors have been shown to be very effective for the treatment of metastatic renal cancer cell. Axitinib is a third-generation inhibitor of vascular endothelial growth factor receptor and is currently being developed for the treatment of various malignancies. The pharmacokinetic properties of axitinib may have a selective therapeutic effect, with minimal adverse reactions and enhanced safety. In a large Phase III study of previously treated patients with metastatic renal cell carcinoma, axitinib achieved a longer progression-free survival than sorafenib with an acceptable safety profile and good quality of life. This review focuses on the pharmacology, pharmacokinetics, and clinical activity of axitinib in the current treatment of renal cell carcinoma. The role of axitinib in the adjuvant and/or neoadjuvant setting needs to be evaluated in further clinical trials.Keywords: axitinib, renal cell carcinoma, vascular endothelial growth factor receptor, angiogenesis

    Co-culture of periodontal ligament fibroblasts (PDLs) and SCC-25 oral squamous carcinoma cells (OSCC) results in conversion of PDLs into carcinoma-associated fibroblasts (CAFs) and induces epithelial-to mesenchymal transition (EMT) of OSCC tumor cells. We hypothesized that Curcumin targets this dynamic mutual interaction between CAFs and tumor cells. Normal and 2 μM Curcumin-treated co-culture were performed for 4 days, followed by analysis of tumor cell invasivity, mRNA/protein expression of EMT-markers and mediators, activity measure of matrix metalloproteinase 9 (MMP-9), and western blot analysis of signal transduction in tumor cells and fibroblasts. In Curcumin-treated co-culture, in tumor cells, the levels of nuclear factor κB (NFκBα) and early response kinase (ERK)—decreased, in fibroblasts, integrin αv protein synthesis decreased compared to corresponding cells in normal co-culture. The signal modulatory changes induced by Curcumin caused decreased release of EMT-mediators in CAFs and reversal of EMT in tumor cells, which was associated with decreased invasion. These data confirm the palliative potential of Curcumin in clinical application. - Graphical abstract: Co-culture of periodontal ligament fibroblasts (PDLs) and SCC-25 oral squamous carcinoma cells (OSCC) results in conversion of PDLs into carcinoma-associated fibroblasts (CAFs) and induces epithelial-to mesenchymal transition (EMT) of tumor cells. Curcumin targets this dynamic mutual interaction between CAFs and tumor cells by inhibiting the production of EMT mediators in CAFs and by modification of intracellular signaling in tumor cells. This causes less invasivity and reversal of EMT in tumor cells. Highlights: ► Curcumin targets tumor–fibroblast interaction in head and neck cancer. ► Curcumin suppresses mediators of epithelial–mesenchymal transition. ► Curcumin decreases the invasivity of tumor cells.

    Full Text Available Objective: The aim of this study was to investigate p53 and COX-2 expressions in basal cell carcinoma, squamous cell carcinoma and actinic keratoses, and to determine a possible relationship.Material and Method: 50 basal cell carcinoma, 45 squamous cell carcinoma and 45 actinic keratosis cases were evaluated. The type of tumor in basal cell carcinoma and tumor differentiation in squamous cell carcinoma were noted and the paraffin block that best represented the tumor was chosen. Immunostaining by p53 and COX-2 was performed on sections of the paraffin blocks.Results: p53 expression was observed in 98% of basal cell carcinoma, 88.9% of squamous cell carcinoma and all actinic keratosis cases. p53 expression was also noted in non-dysplastic appearing epithelium in actinic keratosis cases. COX-2 expression was seen in 90, 100 and 88.9% of the basal cell carcinoma, squamous cell carcinoma and actinic keratosis groups, respectively. Skin appendages, inflammatory cells and vascular structures were also stained by COX-2 besides tumor tissue. COX-2 expression increased by the p53 expression increase in basal cell carcinoma and squamous cell carcinoma. p53 and COX-2 expressions were not related in terms of tumor type in the BCC and were not related in terms of differentiation in SCC.Conclusion: The existence of p53 expression in actinic keratosis cases has supported the idea that p53 plays a role in the early steps of carcinogenesis in skin cancers. The fact that the expression of COX-2 increases in line with the increase of p53 expression in basal cell carcinoma and squamous cell carcinoma cases indicates that COX-2 expression may be affected by p53

  4. Treatment outcome and analysis of the prognostic factors of ductal carcinoma in situ treated with breast conserving surgery and radiotherapy

    International Nuclear Information System (INIS)

    To evaluate the survival rate, local failure rate and patterns of failure, and analyze the prognostic factors affecting local relapse of ductal carcinoma in situ treated with breast conserving surgery and radiotherapy. From June 1995 to December 2001, 96 patients with ductal carcinoma in situ treated with breast conserving surgery and radiotherapy were retrospectively analyzed. The operations were either local or wide excision in all patients, with an axillary lymph node dissection performed in some patients. Radiation dose to the whole breast was 50.4 Gy, over 5 weeks, with 1.8 Gy daily fractions, with additional doses (10 ∼ 14 Gy) administered to the primary tumor bed in some patients with close (≤ 2 mm) or positive resection margin. The median follow-up period was 43 months (range 12 ∼ 102 months). The 5-year local relapse free survival and overall survival rates were 91 and 100% respectively. Local relapse occurred in 6 patients (6.3%). Of the 6 recurrences, one was invasive ductal cell carcinoma. With the exception of one, all patients recurred 2 years after surgery. There was no regional recurrence or distant metastasis. Five patients with local recurrence were salvaged with total mastectomy, and are alive with no evidence of disease. One patient with recurrent invasive ductal cell carcinoma will receive salvage treatment. On analysis of the prognostic factors affecting local relapse, none of the factors among the age, status of resection margin, comedo type and nuclear grade affected local relapse. Operation extent also did not affect local control (ρ = 0.30). In the patients with close resection margin, boost irradiation to the primary tumor bed did not affect local control (ρ = 1.0). The survival rate and local control of the patients with ductal carcinoma in situ treated with breast conserving surgery and radiotherapy were excellent. Close resection margin and boost irradiation to the primary tumor bed did not affect local relapse, but further

  5. Testicular function in patients with differentiated thyroid carcinoma treated with radioiodine

    International Nuclear Information System (INIS)

    The aim of the present study was to assess whether 131I therapy for differentiated thyroid carcinoma (DTC) can affect endocrine testicular function. Serum follicle-stimulating hormone (FSH) and testosterone (T) concentrations were measured in 103 patients periodically submitted for radioiodine therapy for residual or metastatic disease. Mean follow-up was 93.7±54 mo (range 10-243 mo). Mean FSH values in 131I-treated patients tested after their last treatment were 15.3±9.9 mU/ml, significantly higher than those of 19 untreated patients (6.5±3.1 mU/ml). Considering the mean +3 s.d. FSH of untreated subjects as the upper limit of normal range, 36.8% of the patients had an abnormal increase in serum FSH. Longitudinal analysis performed in 21 patients showed that the behavior of FSH in response to 131I therapy was not universal. Six patients had no change or a slight increase in serum FSH after 131I administration; eleven patients had a transient increase above normal values 6-12 mo after 131I treatment, with return to normal levels in subsequent months. The administration of a second dose was followed by a similar increase in FSH levels. Finally, four patients, followed for a long period of time and treated with several 131I doses, showed a progressive increase in serum FSH, which eventually became permanent. Semen analysis, performed in a small subgroup of patients, showed a consistent reduction in the number of normokinetic sperm. No change was found in serum T levels between treated and untreated patients. The results indicate that 131I therapy for thyroid carcinoma is associated with transient impairment of testicular germinal cell function. The damage may become permanent for high-radiation activities delivered year after year and might pose a significant risk of infertility. 14 refs., 8 figs., 1 tab

  6. Carcinoma of penis. Review of cases treated by surgery and radiation therapy 1960-1977

    International Nuclear Information System (INIS)

    Cases of squamous cell carcinoma of the penis treated by surgery and radiation therapy at Moffitt Hospital, University of California, and Mount Zion Hospital and Medical Center are reviewed. Only cases followed for more than three years or with autopsy findings are presented. For the primary lesion, over-all surgical control rate locally was 15/17 or 88 per cent. Over-all control rate with radiation therapy alone was 9/12 (75 per cent), and with surgical salvage 11/12 (92 per cent). Radiation therapy appears to be the treatment of choice for early stage lesions, reserving surgery for salvage. Prophylactic ilioinguinal lymph node dissection for N0 lesions is not warranted. The role of chemotherapy needs further investigation

    2016-02-10

    The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice.A 78-year-old woman with a past medical history of hepatitis C virus (HCV) presented on routine examination to her family doctor with abnormal liver function tests. She was referred for liver ultrasound, which detected a liver mass. Multiphasic magnetic resonance imaging (MRI) diagnosed liver cirrhosis and a segment 7/8 lesion measuring 4 cm, suspicious for a hepatocellular carcinoma (HCC), without evidence of portal hypertension. Child-Pugh (CP) score (ranging from 5 to 15) is a clinically relevant measure of synthetic liver function, based on international normalized ratio and albumin and bilirubin levels, as well as presence or absence of ascites and encephalopathy. A score of A5 or 6 is associated with better postoperative survival compared with CP B7 to 9 or CP C10 to 15, in which surgery is contraindicated. Her CP score was A6, based on a low albumin of 34 g/L. Platelets were slightly depressed at 121,000 μL, and alpha-fetoprotein level was 89 μg/L. She had not received treatment of her HCV because of her age and low viral load. She does not drink alcohol. Clinically the patient had an Eastern Cooperative Oncology Group performance status (PS) of 1, no stigmata of chronic liver disease, and no ascites or encephalopathy or other associated clinical symptoms. An HCC multidisciplinary cancer conference recommended surgical resection. The patient was taken to the operating room for a planned liver nonanatomic wedge resection. At the time of laparotomy

  8. Carcinoma of the nasopharynx treated by radiotherapy alone: determinants of distant metastasis and survival

    International Nuclear Information System (INIS)

    Purpose: This retrospective study was conducted to identify the prognostic factors for distant metastasis and survival in a population of 378 patients with nasopharyngeal carcinomas treated by radiation therapy alone. Materials and methods: All patients were treated at the University of Texas M.D. Anderson Cancer Center between 1954 and 1992, following a consistent dose and volume prescription policy. There were 286 males and 92 females. The median age was 52 years (range: 16-86 years). The majority of the patients were white Caucasians (282 patients, 75%). Tumors were classified as squamous cell carcinomas (193; 51%), lymphoepitheliomas (154; 41%), or unclassified carcinomas (31, 8%). Three fourths of the patients presented with AJCC Stage IV disease (T4, N0-3, 118 patients; T1-3, N2-3 164 patients). The treatment techniques included opposed lateral fields with or without an anteroposterior or an anterior oblique pairs for dose supplementation to the primary site. Average total doses per T-stage ranged between 60.2 and 72.0 Gy. Median follow-up time was 10 years (range 0.3 to 28.6 years). Results: A total of 103 patients (27%) developed distant metastases at a median time of 8 months (range: 1-90 months). Actuarial rates for distant metastasis were 30%, 32%, 32% at 5, 10, and 20 years, respectively. Actuarial rates for disease specific survival at the same time points were 53%, 45%, and 39% with 184 patients (49%) dying of their nasopharyngeal cancer. Advanced T-stage, N-stage, and non-lymphoepithelioma histology were independent adverse prognostic factors for disease specific survival. Advanced N-stage and low neck disease were independent adverse prognostic factors for distant metastasis with a very high rate of distant metastases for those patients who presented with both adverse factors (relative risk 7.86). On average, patients with distant metastasis lived 5 months after they were diagnosed with metastatic disease (range: 0-172 months), although four

    Full Text Available Renal cell carcinoma is one of the most common tumours after lung and breast cancer to metastasize to the head and neck. Initial presentation by tongue metastasis is extremely rare. A 67-year-oldmale presented with a 4.8 cm mass on his tongue. The result of the punch biopsy from the tongue was diagnosed as a clear cell variant of squamous cell carcinoma. The biopsy was reevaluated due to the renal mass found during the check-up and the rapid enlargement of the mass. The excision of the tongue mass and the radical nephrectomy material confirmed the diagnosis of a metastatic renal cell carcinoma in the tongue and renal cell carcinoma in the kidney. Since metastasis of renal cell carcinoma to the tongue is uncommon it may cause difficulties in diagnosis and proper management. The metastasis of renal cell carcinoma should always be considered in the differential diagnosis among the clear cell neoplasms.

    Full Text Available We report a case of synchronous bilateral adrenal metastasis of renal cell carcinoma. The contralateral metastatic adrenal mass was treated by the laparoscopic transperitoneal approach. The renal mass and its huge ipsilateral metastatic adrenal gland were removed en bloc with open procedure. A 54-year-old man presented to our clinic with left-sid renal cell carcinoma synchronously bilateral adrenal metastases. The primary tumor was localized in the upper-mid pole of the kidney. The diagnosis was established preoperatively by computed tomography. The size of the contralateral adrenal mass was 65 x 45 mm, but the ipsilateral metastatic adrenal mass was huge (140 x 65 mm. After all analysis and other scannings for any metastasis, a contralateral lapararoscopic transperitoneal adrenalectomy and a left open nephroadrenalectomy were performed simultaneously. Synchronous bilateral adrenal metastases from primary renal cell carcinoma without another metastasis is very rare. The optimal surgical procedure should be selected according to the metastatic adrenal masses size and the patient%u2019s status.

    Full Text Available Context Squamous carcinoma of the ampulla of Vater is a very rare tumor with only three cases been reported so far. Case report Here, we report the case of a 68-year-old man who presented with painless obstructive jaundice, general fatigue, loss of appetite and weight loss. Laboratory tests revealed hypochromic anemia. Total and direct bilirubin, alkaline phosphatase, liver enzymes, carbohydrate antigen 19-9 (CA 19-9 and carcinoembryonic antigen (CEA were all elevated. Abdominal ultrasonography and computed tomography showed a distended gallbladder, dilatation of the intra- and extra-hepatic bile ducts and enlargement of the pancreatic head. Endoscopic retrograde cholangiopancreatography revealed a bulging papilla with infiltrative growth at the ampulla of Vater but endoscopic biopsies were inconclusive. The patient was treated with classical Whipple’s pancreaticoduodenectomy. Histopathological examination showed a moderately differentiated squamous cell carcinoma. Multiple serial sectioning of the tumor specimen failed to detect an adenomatous component. Regional lymph nodes and resection margins were free of tumor and the disease was classified as stage IIA (T3N0M0 according to the TNM system. Adjuvant treatment was not given. Despite curative resection, multiple liver metastases developed after four months and the patient succumbed to progressive hepatic failure 5 months after the operation. Conclusion Primary pure squamous cell carcinoma of the ampulla of Vater is a very rare histological type of carcinoma. Clinical characteristics and optimal treatment are obscure. Primary surgical treatment with curative intent should be performed although this type of carcinoma associates with dismal prognosis.

  16. Coexpression of cyclooxygenase-2 and thymidine phosphorylase as a prognostic indicator in patients with FIGO stage IIB squamous cell carcinoma of uterine cervix treated with radiotherapy and concurrent chemotherapy

    International Nuclear Information System (INIS)

    Purpose: To evaluate the prognostic significance of thymidine phosphorylase (TP) and coexpression of cyclooxygenase-2 (COX-2)/TP, and to investigate the relationship between COX-2 and TP expression in squamous cell carcinoma of the uterine cervix. Methods and Materials: Cancer specimens from 75 patients with International Federation of Gynecology and Obstetrics Stage IIB squamous cell carcinoma of the uterine cervix who had undergone radiotherapy and concurrent chemotherapy were immunohistochemically stained with COX-2 and TP antibodies and scored. The prognostic significance of their expression status, and the relationship between COX-2 and TP was investigated. Results: TP predominantly stained cytoplasm and the cell membrane of the tumor cells mainly in a diffuse and intense manner. TP was negative (50%) in 57% of patients. TP overexpression was related to a marginal prognostic significance of a poor 5-year overall survival (p = 0.082, log-rank test) and a high locoregional recurrence rate (p < 0.1, chi-square test). COX-2 and TP coexpression was observed in 24% of patients and was significantly related to poor 5-year disease-free and overall survival rates (p = 0.0083 and p 0.025, respectively), a high pelvic lymph node involvement rate, a poor response to treatment, and a greater incidence of locoregional recurrence (p < 0.05). By multivariate analyses, only COX-2, TP, and coexpression of COX-2/TP were significant independent prognostic indicators of patient survival. All tumors showed 1+ or 2+ TP expression when COX-2 was positive, and no tumor expressed COX-2 when TP was negative (p = 0.03). In contrast, 77% of tumors expressed 1+ or 2+ TP without the synchronous expression of COX-2. Conclusions: Thymidine phosphorylase expression or COX-2/TP coexpression may be used as a molecular prognostic marker for squamous cell carcinoma of the uterine cervix. TP appears to be an important downstream molecule of COX-2 during angiogenesis and may be a new target for the

    A 69-year-old white Italian woman was first seen at Memorial Sloan-Kettering Cancer Center in 1981 concerning several skin growths on her back. The patient had had several basal cell carcinomas surgically removed from her back during the preceding 5 years. There was no history of arsenic ingestion or prolonged sun exposure and her family history was negative for skin cancer. The patient had developed pulmonary tuberculosis in 1938 and was treated with pneumothorax therapy. She had had more than 50 fluoroscopic examinations of the chest following this therapy, as well as multiple diagnostic x-ray films since that time. On the back, clustered in the interscapular region, were multiple scars and nine erythematous nodules with pearly borders, telangiectasia, and translucent surfaces. Within several nodules there were areas of light and dark brown pigmentation. Biopsy of all lesions revealed basal cell carcinoma, some of which were pigmented, without evidence of chronic radiodermatitis. All lesions were treated with curettage and electrodesiccation three times with good cosmetic results

    Basal cell carcinoma (BCC) presents with diverse clinical features, and several morphologic and histologic variants of BCC have been reported [Sexton et al.: J Am Acad Dermatol 1990;23:1118-1126]. Linear BCC was first described as a new clinical subtype in 1985 by Lewis [Int J Dematol 1985;24:124-125]. Here, we present a case of linear BCC that we recently encountered in an elderly Japanese patient, and review other cases reported in Japan.

    Basal cell carcinoma (BCC) is the most common nonmelanoma skin cancer. Most BCCs are found on areas of UV-damaged skin, The study of BCCs of sun-protected regions, however, suggests a more complex pathogenesis. We present a case of BCC of the perineum in a man with no previous history of skin cancer. This is the first report of BCC in this region and one of a small body of cases arising on or near the genital and perianal regions.

    A 64-year-old male presented with lower back pain, radiating in a sciatic-type distribution, swelling in his lower abdomen and right leg, and edema of the scrotum and penile shaft. A sonogram and CT imaging indicated an enhancing mass in the right kidney and a spinal metastasis. The right lower extremity and penoscrotal lymphedema was caused by lymphatic obstruction due to a sacral metastasis of renal cell carcinoma. He was treated with cytoreductive nephrectomy, radiation and a systemic tyrosine kinase inhibitor. Pelvic imaging is suggested to determine whether malignant lymphatic obstruction is present when presented with idiopathic penoscrotal edema. PMID:26267035

    1984-11-01

    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.

    A multifocal biphasic squamoid alveolar renal cell carcinoma in a 68-year-old man is reported. Four different peripheral tumor nodules were identified on gross examination. A fifth central tumor corresponded to a conventional clear cell renal cell carcinoma. Biphasic squamoid alveolar renal cell carcinoma is a rare tumor that has been very recently characterized as a distinct histotype within the spectrum of papillary renal cell carcinoma. Immunostaining with cyclin D1 seems to be specific of this tumor subtype. This is the first reported case with multifocal presentation. PMID:27158455

    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.

  4. Multiple basal cell carcinomas arising in a port-wine stain with a remote history of therapeutic irradiation

    International Nuclear Information System (INIS)

    The coexistence of a basal cell carcinoma and a port-wine stain is a very rare condition that may be associated with previous treatments. We present a case of multiple basal cell carcinomas developing within the boundaries of a port-wine stain, which had been treated with a tholium X and argon laser. Our case suggests that port-wine stains which were previously treated with irradiation or argon laser should be examined carefully and regularly by both physician and patient, because they may hide basal cell carcinomas.

  5. Radiotherapy preserves fingers in the management of subungual squamous cell carcinoma, obviating the need for amputation

    International Nuclear Information System (INIS)

    A retrospective study of the use of radiotherapy in 12 patients with subungual squamous cell carcinoma of the finger was conducted at two radiotherapy departments in the Netherlands. This malignancy has little tendency to metastasize and is usually treated by amputation. Primary radiotherapy resulted in a permanent local control of 92% with only one serious adverse effect leading to an amputation of the initially involved digit. No regional or distant failure was seen during follow-up. Radiotherapy should be considered as an alternative for amputation to treat patients with subungual squamous cell carcinoma of the finger

    Squamous cell carcinoma ofthe anal canal represents 1.5% of all malignancies affectingthe gastrointestinal tract. Over the past 20 years dramatic changes have been seen in both the epidemiological distribution of the disease and in the therapeutic modalities utilised to manage it. CLINICAL MANAGEMENT: Historically abdominoperineal resection had been the treatment of choice with local resection reserved for early stage disease. Work by Nigro et al. has revolutionised how we currently manage carcinoma of the anal canal, demonstrating combined modality chemoradiotherapy as an appropriate alternative to surgical resection with the benefit of preserving sphincter function. Surgery is then reserved for recurrent disease with salvage abdominoperineal resection. This article reviews current literature and highlights the changing therapeutic modalities with selected clinical cases

    Full Text Available Abstract Introduction Merkel cell carcinoma is a rare malignant cutaneous neoplasm that is locally invasive and frequently metastasizes to lymph nodes, liver, lungs, bone and brain. The incidence of Merkel cell carcinoma has increased in the past three decades. Case presentation A 65-year-old Caucasian man presented with a sudden onset of severe headache and a three-month history of balance disturbance. Magnetic resonance imaging revealed a large meningeal metastasis. The radiologic workup showed retroperitoneal and inguinal lymph node metastases. Biopsy of the inguinal lymph nodes showed metastases of Merkel cell carcinoma. Biopsy from three different suspected skin lesions revealed no Merkel cell carcinoma, and the primary site of Merkel cell carcinoma remained unknown. Leptomeningeal metastases, new axillary lymph node metastases, and intraspinal (epidural and intradural metastases were detected within six, seven and eight months, respectively, from the start of symptoms despite treating the intracranial metastasis with gamma knife and the abdominal metastases with surgical dissection and external radiotherapy. This indicates the aggressive nature of the disease. Conclusion To the best of our knowledge, this is the first report in the literature of an intracranial meningeal metastasis of Merkel cell carcinoma treated with gamma knife and of intraspinal intradural metastases of Merkel cell carcinoma. Despite good initial response to radiotherapy, recurrence and occurrence of new metastases are common in Merkel cell carcinoma.

    2016-08-01

    Primary squamous cell carcinoma of the thyroid gland is rare, and mixed squamous cell and follicular carcinoma is even rarer still, with only a few cases reported in the literature. The simultaneous presentation of three primary cancers of the thyroid has not been reported previously. Here we report a case of primary squamous cell carcinoma of the thyroid, follicular thyroid carcinoma, and micropapillary thyroid carcinoma. A 62-year-old female patient presented with complaints of pain and a 2-month history of progressively increased swelling in the anterior region of the neck. Fine-needle-aspiration cytology of both lobes indicated the possibility of the presence of a follicular neoplasm. Total thyroidectomy with left-sided modified radical neck dissection was performed. Postoperative pathological examination confirmed the diagnosis of thyroid follicular carcinoma with squamous cell carcinoma and micropapillary carcinoma of the thyroid. Thyroid-stimulating hormone suppressive therapy with l-thyroxine was administered. Radioiodine and radiotherapy also were recommended, but the patient did not complete treatment as scheduled. The patient remained alive more than 9 months after operation. The present case report provides an example of the coexistence of multiple distinct malignancies in the thyroid. PMID:26589365

  20. Potential of HSV-TK gene in gene-radiotherapy for human bladder carcinoma cells

    International Nuclear Information System (INIS)

    Objective: To explore the killing effect of retrovirus-mediated HSV-TK/GCV system combined with radiotherapy on human bladder carcinoma cells. Methods: By using retrovirus-mediated gene transfer technique, hygromycin phosphotransferase-thymidine kinase fusion gene (HyTK) was transferred into EJ bladder carcinoma cells. Antitumor effects were observed after irradiation with 60Co γ-rays as well as gancyclovir treatment. Results: EJ bladder carcinoma cells transduced with HyTK gene and treated with low concentrations of gancyclovir, which alone showed little cytotoxicity, were highly sensitive to radiation. The sensitizer enhancement ratio (SER) was 1.36. Conclusion: The combination of retrovirus-mediated HyTK/GCV gene therapy with standard radiation therapy might improve the therapeutic effectiveness for bladder carcinoma in clinical practice

    2016-01-01

    Acanthosis nigricans (AN), an entity recognized since the 19th century, is a dermatopathy associated with insulin-resistant conditions, endocrinopathies, drugs, chromosome abnormalities and neoplasia. The latter, also known as malignant AN, is mostly related to abdominal neoplasms. Malignant AN occurs frequently among elderly patients. In these cases, the onset is subtle, and spreading involves the flexural regions of the body, particularly the axillae, palms, soles, and mucosa. Gastric adenocarcinoma is the most frequent associated neoplasia, but many others have been reported. Renal cell carcinoma (RCC), although already reported, is rarely associated with malignant AN. The authors report the case of a woman who was being treated for depression but presented a long-standing and marked weight loss, followed by darkening of the neck and the axillary regions. Physical examination disclosed a tumoral mass in the left flank and symmetrical, pigmented, velvety, verrucous plaques on both axillae, which is classical for AN. The diagnostic work-up disclosed a huge renal mass, which was resected and further diagnosed as a RCC. The post-operative period was uneventful and the skin alteration was evanescent at the first follow-up consultation. The authors call attention to the association of AN with RCC. PMID:27284539

The female:male ratio was 2.4:1 and the median age at presentation was 70 (range 38-92) years. All patients had a thyroid mass at presentation and the most common symptoms were dyspnoea, dyspnagia and dysphonia. Five patients had a total thyroidectomy and 28 partial thyroidectomy. Ninety five per cent of patients received external beam radiotherapy. Results show dyspnoea to be the only symptom strongly influencing survival. Total or partial thyroidectomy is associated with increased survival. This association is most marked for patients presenting without dyspnoea. Eighty per cent of patients responded to radiotherapy.

    Ninety-one patients with histologically proven anaplastic carcinoma of the thyroid were referred to the Beatson Oncology Centre between 1961 and 1986. The female:male ratio was 2.4:1 and the median age at presentation was 70 (range 38-92) years. All patients had a thyroid mass at presentation and the most common symptoms were dyspnoea, dysphagia and dysphonia. Five patients had a total thyroidectomy and 28 partial thyroidectomy. Ninety five per cent of patients received external beam radiotherapy. Results show dyspnoea to be the only symptom strongly influencing survival. Total or partial thyroidectomy is associated with increased survival. This association is most marked for patients presenting without dyspnoea. Eighty per cent of patients responded to radiotherapy.

    Squamous cell carcinoma (SCC) of the endometrium, whether primary or secondary to cervical cancer, is a rare entity. Primary endometrial squamous cell carcinoma in situ is even more uncommon; it usually occurs in postmenopausal women and has a strong association with pyometra. We report a 60-year-old multiparous postmenopausal woman who presented to the Hakeem Abdul Hameed Centenary Hospital, New Delhi, India, in May 2014 with a lower abdominal swelling corresponding in size to a pregnancy of 26 gestational weeks and vaginal discharge of one year’s duration. A total abdominal hysterectomy with a bilateral salpingooophorectomy was performed, which revealed an enlarged uterus with pyometra. Histopathology showed that the entire endometrial lining had been replaced with malignant squamous cells without invasion of the myometrium. Immunohistochemistry revealed that the tumour cells were positive for p63 with a high Ki-67 labelling index. No adjuvant therapy was required and the patient was disease-free at a seven-month follow-up. PMID:26629388

    Recently, vitamin D analogues have shown antineoplastic effect in several diseases. Vitamin D analogues exert its effect by interacting with the vitamin D receptor (VDR). Studies of VDR in transitional cell carcinoma (TCC) have not been reported. The purpose of the present study was therefore.......05). Similarly, also tumor grade appeared to be related to the number of cells expressing the receptor. Normal urothlium also expressed VDR but only with low intensity. Our study shows that TCC cells possess the VDR receptor which may make them capable to respond to stimulation with vitamin D, but functional...... studies of vitamin D's effect on TCC cells in vitro are necessary before the efficacy of treatment with vitamin D analogues in TCC can be evaluated in patients....

    Malignant melanoma can be successfully treated when it is identified in its early stages, but the disease is associated with a poor prognosis when it is detected in an advanced stage. Papillary thyroid carcinoma is a thyroid cancer that has a good prognosis. The present study reports a rare case of malignant melanoma and papillary thyroid carcinoma that were diagnosed concurrently and treated simultaneously. The present patient was a 37-year-old male, in whom examination of a skin biopsy that was obtained from a lesion in the right retroauricular region revealed the lesion to be consistent with malignant melanoma. The patient underwent radical neck dissection upon the detection of malignant melanoma metastasis to the sentinel lymph node. Metastases of papillary thyroid carcinoma were detected in four out of 38 lymph nodes. The patient was then diagnosed with papillary thyroid carcinoma and underwent total thyroidectomy. The patient was administered with high-dose followed by moderate-dose interferon-α therapy for the treatment of malignant melanoma. The patient also received concurrent radioactive iodine therapy for the treatment of papillary thyroid carcinoma, at the same time as the interferon therapy. The two primary tumors of the patient were treated successfully. During therapy, no serious side-effects were observed, with the exception of fever caused by high-dose interferon therapy. Malignant melanoma and papillary thyroid carcinoma may occur concurrently, although this is rarely observed. The present study reports a rare case that demonstrates that the two tumors can be successfully treated simultaneously. PMID:25436010

    Full Text Available Granuloma inguinale (GI is an acquired chronic, slowly progressive, mildly contagious disease of venereal origin, characterized by granulomatous ulceration of the genitalia and neighboring sites, with little or no tendency to spontaneous healing caused by Klebsiella (Calymmatobacterium granulomatis. A 55-year-old male presented with fissured, foul smelling, fungating growth over prepuce with phimosis mimicking squamous cell carcinoma (SCC without lymphadenopathy. It started with painless papulonodular showed pseudoepitheliomatous hyperplasia, infiltration in dermis, acanthosis and vacuolated macrophages suggestive of GI and not showing any histopathological features of SCC. Patient was successfully treated by giving cotrimoxazole twice a day for 21 days. Here, we presented a case of GI mimicking SCC of penis, which was diagnosed on basis of histopathology and treated with excision followed by medical therapy with cotrimoxazole.

    Aggressive prostatic carcinomas most frequently metastasize to the skeletal system. We have previously shown that cultured human prostatic carcinoma cells are highly responsive to growth factors found in human bone marrow. To identify the factor(s) responsible for the increased prostatic carcinoma cell proliferation, we fractionated crude bone marrow preparations by using hydroxylapatite HPLC. The major activity peak contained two high molecular weight bands (M(r) = 80,000 and 69,000) that cr...

    Background Our preliminary data on the protein expression of SORT1 in ovarian carcinoma tissues showed that sortilin was overexpressed in ovarian carcinoma patients and cell lines, while non-malignant ovaries expressed comparably lower amount of this protein. In spite of diverse ligands and also different putative functions of sortilin (NTR3), the function of overexpressed sortilin in ovarian carcinoma cells is an intriguing subject of inquiry. The aim of this study was, therefore, to investi...

    Basal cell carcinoma (BCC) is the most frequent non-melanoma skin cancer. Only 5-15% of BCC cases can be found in patients aged 20-40 years (so-called early onset). The early onset BCC is characterized by active and aggressive tumour growth, clinically presenting in most of the cases as a morpheaform, locally infiltrating or recurrent BCC. Despite the advances in the study of the pathogenesis of this tumour, surgery remains the most used, most effective and most suitable treatment modality. W...

  17. Percutaneous Cryoablation for Renal Cell Carcinoma

    Directory of Open Access Journals (Sweden)

    2015-06-01

    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.

  18. Aldesleukin in advanced renal cell carcinoma.

    Schmidinger, Manuela; Hejna, Michael; Zielinski, Christoph C

    2004-12-01

    Renal cell carcinoma accounts for 2-3% of all malignancies. The most common subtype [85%] is the clear cell variant. A total of 30% of patients present with metastatic disease at diagnosis and another 30-40% will develop metastases during the course of the disease. Conventional cancer treatment is not effective, but cytokines including recombinant interleukin-2 (aldesleukin) have demonstrated clinical activity of various degrees. This drug profile provides a review of the literature on studies using aldesleukin in patients with metastatic renal cell carcinoma. Aldesleukin has been used in different dose schedules applying various administration routes, as either monotherapy or in combination with other cytokines, chemotherapy, endocrine treatment and adoptive cellular immunotherapy. Although a large number of randomized trials have been performed with different treatment strategies, it still remains uncertain whether the dose or combination of aldesleukin with other agents substantially influence treatment outcome. It appears that factors other than those that are treatment related are responsible for the course of the disease. PMID:15606326

  19. CT findings of signet ring cell carcinoma of the stomach

    International Nuclear Information System (INIS)

    Signet-ring cell carcinoma is rather invasive and infiltrative than other histologic types of gastric cancer. We evaluated the characteristic CT findings of signet-ring cell carcinoma especially in the intensity and pattern of contrast enhancement. We analyzed the CT findings of 22 cases with histologically proven signet-ring cell carcinoma, and compared them with those of 35 cases with histologically proven tubular adenocarcinoma. The double ring enhancement of the gastric mass was seen in 12 cases of signet-ring cell carcinoma and only one case of tubular adenocarcinoma. The masses of signet-ring cell carcinoma were enhanced more by the CT number of 10.2 than those of tubular adenocarcinoma. Of the masses of signet-ring cell carcinoma, those showed double ring enhancement were more intensely enhanced than those showed diffuse enhancement by the CT number of 22.9. We thought that neovascularity and different infiltration of the tumor cells in the gastric wall were responsible for the intense enhancement and double ring sign of signet-ring cell carcinoma. The possibility of signet-ring cell carcinoma is high if a gastric mass show double ring sign and strong contrast enhancement

  20. P53 and radiation response. The impact of oncogene activation in oesophagus carcinoma treated by radiotherapy only

    International Nuclear Information System (INIS)

    We studied a group of patients with locally advances oesophageal carcinoma, managed by radiotherapy exclusively, and determined the p53 protein expression by immunohistochemistry (IHC), in relationship to local control and survival. IHC for p53 protein was performed on paraffin-embedded specimens from 69 patients with adeno- and squamous cell carcinoma of the oesophagus. All patients were treated by external beam irradiation combined with intraluminal brachytherapy. Fifty-four percent (37/69) of the tumours showed overexpression of the p53 protein. No correlation with pretreatment parameters for p53-positive and p53-negative cases was detected. Overall survival as well as distant metastases-free survival was superior for p53 negative tumours. Local recurrence free-survival was slightly better in the p53 negative group, but this was dose dependent. (author)

    Engulfment and cell motility 1 (Elmo1) has been linked to the invasive phenotype of glioma cells. The use of Elmo1 inhibitors is currently being evaluated in hepato-cellular carcinoma (HCC), but the molecular mechanisms of their therapeutic effect have yet to be determined. Elmo1 expression in HCC tissue samples from 131 cases and in 5 HCC cell lines was determined by immunohistochemistry, quantitative RT-PCR and Western blotting. To functionally characterize Elmo1 in HCC, Elmo1 expression in the HCCLM3 cell line was blocked by siRNA. Cell migration was measured by wound healing and transwell migration assays in vitro. Elmo1 overexpression was significantly correlated with cell invasion and the poor prognosis of HCC. Elmo1-siRNA-treated HCCLM3 cells demonstrated a reduction in cell migration. The present study demonstrated for the first time that the suppression of Elmo1 expression inhibits cell invasion in HCC. PMID:22977532

    Background Glypican 3 (GPC3) is a member of the family of glypican heparan sulfate proteoglycans (HSPGs). The GPC3 gene may play a role in controlling cell migration, negatively regulating cell growth and inducing apoptosis. GPC3 is downregulated in several cancers, which can result in uncontrolled cell growth and can also contribute to the malignant phenotype of some tumors. The purpose of this study was to analyze the mechanism of action of the GPC3 gene in clear cell renal cell carcinoma. ...

    2013-01-01

    Full Text Available Solitary necrotic nodule of the liver is a rare benign lesion with a completely necrotic core and a hyalinized fibrotic capsule containing elastic fibers. The pathogenetic mechanism is still unclear. We here describe a case of SNN, whose central reticulin fibers within the nodule suggest the origin as hepatocellular carcinoma or other hepatocyte-origin tumors, treated with laparoscopic anatomical segmentectomy of the liver. A 76-year-old Japanese female, with no prior medical history and no symptom, visited our hospital with the heterogeneous hypoechoic lesion in the liver segment VI incidentally pointed out in abdominal ultrasonography. Computed tomography with contrast demonstrated a 1.1 cm sized low-density lesion with mild ring enhancement on the rim in the arterial phase. Since the possibility of malignant tumor with necrotic change could not be ruled out, she underwent laparoscopic anatomical segmentectomy of the liver. In the histological examination of the surgical specimen, the liver nodule was necrotic tissue without viable cells and signs of inflammation, which had fibrous capsule and central cystic change and showed trabecular pattern alignment of ghost cells and reticulin fibers orthogonal to the capsule. Also, the findings of chronic hepatitis were observed in the background liver.

We found three genes encoding metallothioneines that showed reduced expression in different types of renal tumors, using protocol of the cross-platform meta-analysis of microarray data with normalization on several reference genes. Decreased expression of the MT1G, MT1F, and MT1H genes in clear cell renal cell carcinoma was confirmed by qPCR. Conclusions. The MT1G, MT1F and MT1H genes as well as may be considered as the candidate tumor suppressor genes for ccRCC.

  5. 11C-Acetate PET imaging for renal cell carcinoma

    International Nuclear Information System (INIS)

    In this study, we investigated the effectiveness of positron emission tomography (PET) with 11C-acetate (AC) for evaluation of renal cell carcinoma. Enrolled in the study were 20 patients with suspected renal tumour, one of whom had three renal lesions. In all, 22 renal lesions were evaluated. Following administration of 350 MBq (10 mCi) of AC, whole-body PET images were obtained. Based on these PET findings, kidney lesions were scored as positive or negative. The PET results were correlated with the CT findings and histological diagnosis after surgery. In 18 patients, 20 tumours were diagnosed as renal cell carcinoma. Lesions in the remaining two patients were diagnosed as complicated cyst without malignant tissue. Of the 20 renal cell carcinomas. 14 (70%) showed positive AC PET findings; 6 were negative. The two patients with complicated cyst had negative AC PET findings. Of the 20 renal cell carcinomas, 19 were clear-cell carcinoma and 1 was a papillary cell carcinoma. This papillary cell carcinoma showed high AC uptake. AC demonstrates marked uptake in renal cell carcinoma. These preliminary data show that AC is a possible PET tracer for detection of renal cancer.

  8. T but not N stage predicts survival for patients with tonsillar carcinoma treated with external radiotherapy and brachytherapy

    International Nuclear Information System (INIS)

    Background. Our aim was to determine the efficacy of a therapeutic schedule including external radiation and brachytherapy in a consecutive and retrospective series of tonsillar carcinoma patients. Patients and methods. Ninety-six patients with tonsillar carcinoma were treated between 1988 and 2000 and were followed up for at least for three years. All patients were treated with accelerated hyperfractionated external radiotherapy, 68 patients had additional brachytherapy and 69 patients with advanced stages also received chemotherapy. There was no planned surgery even though 73% had N+ disease. Eleven patients with persistent neck nodes underwent ultimate salvage surgery. Results. The overall three-year survival (OS) was 70%. OS for the T stage was T1 90%, T2 89%, T3 54% and T4 60%. The corresponding numbers for the N stage were N0 61.5%, N1 73%, N2 78% and N3 66%. Accordingly OS was influenced by the T stage (p>0.001) rather than by N stage. Only four patients with salvage surgery had viable tumour cells in the specimen, their survival was not inferior. Discussion. The primary tumour stage is an essential determinant for survival in patients with irradiated tonsillar carcinoma. Neck dissection should be confined only as a salvage procedure

  9. Mechanical Stress Promotes Cisplatin-Induced Hepatocellular Carcinoma Cell Death

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Cisplatin (CisPt is a commonly used platinum-based chemotherapeutic agent. Its efficacy is limited due to drug resistance and multiple side effects, thereby warranting a new approach to improving the pharmacological effect of CisPt. A newly developed mathematical hypothesis suggested that mechanical loading, when coupled with a chemotherapeutic drug such as CisPt and immune cells, would boost tumor cell death. The current study investigated the aforementioned mathematical hypothesis by exposing human hepatocellular liver carcinoma (HepG2 cells to CisPt, peripheral blood mononuclear cells, and mechanical stress individually and in combination. HepG2 cells were also treated with a mixture of CisPt and carnosine with and without mechanical stress to examine one possible mechanism employed by mechanical stress to enhance CisPt effects. Carnosine is a dipeptide that reportedly sequesters platinum-based drugs away from their pharmacological target-site. Mechanical stress was achieved using an orbital shaker that produced 300 rpm with a horizontal circular motion. Our results demonstrated that mechanical stress promoted CisPt-induced death of HepG2 cells (~35% more cell death. Moreover, results showed that CisPt-induced death was compromised when CisPt was left to mix with carnosine 24 hours preceding treatment. Mechanical stress, however, ameliorated cell death (20% more cell death.

    Full Text Available Kidney cancer (renal cell carcinoma is one of the major problems of modern urological oncology. In Russia renal cell carcinoma accountsfor 4.3 % of all cancers. The global incidence of renal cell carcinoma has increased over the past two decades. Worldwide renal cell carcinoma accounts for 3.6 % of all cancers and is 10th frequent malignancy. For some malignancies, for instance tumours of prostate, there are markers known that allowed improved early diagnostics. Kidney cancer, however, remains to be hard to diagnose and to treat, since the symptoms can be detected on advanced stages of the disease. In Russia 75.4 % of renal cell carcinoma cases detected at the stage of local and locally advanced disease. Though there are various target drugs on the market aimed to treat this disease, the results of renal cell carcinoma treatment did not reach any substantial success. Most of existing target drugs for kidney cancer treatment include inhibitors of a single signalingpathway regulated by VHL1, which expression is lost in the vast majority of renal-cell carcinomas. Till now existing drugs did not reach sufficient efficacy. Therefore, it is highly important to search for new signaling pathways, regulating such cellular processes as proliferation, migration and apoptosis. Further, prognostic markers and therapy targets identified so far are not sufficient and poorly specific. Therefore identification and validation of new markers, and especially new specific targets for the treatment of kindey oncopathologies is highly important and timely task.

    Full Text Available Reena Kabaria, Zachary Klaassen, Martha K Terris Department of Surgery, Section of Urology, Augusta University, Augusta, GA, USA Abstract: This review provides an overview of the incidence of renal cell carcinoma (RCC and a summary of the most commonly associated risk factors. A literature review was performed with a focus on recent studies with a high level of evidence (large prospective cohort studies and meta-analyses. The incidence rate of RCC varies globally, with the rate rising rapidly in more developed regions, demonstrating the effects of increased use of diagnostic imaging and prevalence of modifiable risk factors. Based on the current evidence, cigarette smoking, obesity, and hypertension are the most well-established risk factors for sporadic RCC worldwide. Acquired cystic kidney disease is also a significant risk factor, specifically in dialysis patients. There is increasing evidence for an inverse association between RCC risk and moderate alcohol consumption. Certain analgesics and occupational exposure have been linked to an increased risk of RCC, although data are limited. Diets rich in fruits and vegetables may provide a protective effect.

    Incidental papillary carcinoma of the thyroid in patients treated surgically for benign thyroid diseases including Graves' disease is a known phenomenon. However, the management of these patients remains an issue of concern and controversy for those who care for them. We report a case of metastatic papillary carcinoma of the thyroid in a patient previously treated for Graves' disease. The subject of this presentation is a 50-year-old lady who was diagnosed with Graves' disease at the age of 29, for which she had a subtotal thyroidectomy following failure of medical and radioactive iodine treatment. Three years later, the patient was referred to our nuclear medicine department with a clinical diagnosis of suspected metastatic lymph nodes presumably from a thyroid malignancy.She had an 123I diagnostic whole body scan that showed 123I avid areas in the thyroid bed as well as left cervical lymph nodes, which later turned out to be metastatic papillary carcinoma of the thyroid on histology. She was treated with therapeutic doses of 131I. Follow-up radioactive iodine scans and serum thyroglobulin assays showed no evidence of malignant thyroid tissue. The occurrence of papillary carcinoma of the thyroid after a subtotal thyroidectomy for Graves' disease is hereby reported. The need for vigilance and regular follow-up in patients who receive all forms of treatment for benign thyroid diseases is emphasized. PMID:24705115

    International Nuclear Information System (INIS)

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

    Background Prognostic factors in predicting outcomes in patients with head and neck squamous‐cell carcinoma (HNSCC) are limited to the clinical–pathological parameters, including lymph node metastasis, location, grade and stage of the disease. Aim To determine whether the expression of these proteins has a value in predicting patient outcome. Methods Ezrin, maspin and nm23‐H1 immunohistochemistry in tissue samples of 120 patients with HNSCC were evaluated using the microarray technique. Results In determining the association among each of the three proteins and the clinical–pathological parameters, low maspin expression was the only one found to be significantly associated with high tumour grade (p = 0.007); all others showed no significant associations. In univariate analysis, patients with tumours expressing high ezrin had a shorter disease‐free survival (DFS) of 51% than those with low ezrin expression (DFS 84%; p = 0.08). In multivariate analysis, tumours with the combination of loss of maspin and low histological grade had longer DFS (83%) compared with those with high maspin and high histological grade (DFS 42%; p = 0.08). Conclusion Our study is the first to determine the value of ezrin and maspin in HNSCC in a large series of patients with long follow‐up. Ezrin and maspin seem to have a potential prognostic value in patients with HNSCC but results should be confirmed with further studies. PMID:16698950

    Full Text Available True metastases to prostate from solid tumors are reported only in 0.2% of all surgical prostatic specimens and 2.9% of all male postmortems. Clinical context, morphological features, and immunohistochemical localization of prostate specific antigen (PSA are supposed to clarify the differential diagnosis between a secondary and a primary tumor. We report an unusual and rare case of secondary signet ring cell carcinoma (SRCC of prostate in which the clinical data and signet ring cell morphology pointed toward the diagnosis of a primary SRCC. Immunohistochemistry (IHC for PSA not only proved the case to be a secondary SRCC but also initiated the process for diagnosis of the occult primary malignancy in the patient′s stomach.

  1. Salvage surgery for local failure of oral squamous cell carcinoma

    International Nuclear Information System (INIS)

    Local failure rates following treatment for squamous cell carcinoma of the oral cavity have been reported to be in the range of 25%-48%. This study investigated the pattern of failure for squamous cell carcinoma (SCC) of the oral cavity and evaluated salvage surgery for local recurrent disease. The tumor files of 549 patients undergoing treatment for SCC of the oral cavity between 1980 and 2000 at Chiba Cancer Center Hospital were reviewed. Of 549 patients, 289 were initially treated with radiation therapy for their primary tumor, and 260 with surgery, either with or without radiation therapy. One hundred and sixty-one patients developed failures, yielding a failure rate of 29.3%. The site of recurrent tumor was local in 72 (13.1%) patients, regional in 89 (16.2%) patients, and distant in 5 (0.9%) patients. Local failure developed in 49 (17.0%) patients with radiation therapy and in 23 (8.8%) patients with surgery. Out of these 72 patients with local failure, 41 (56.9%) patients had salvage surgery for their disease. Twenty-five (73.5%) of the 34 patients initially treated with radiation therapy were salvaged with surgery, and 4 (57.1%) of the 7 patients initially treated with surgery were cured with further surgery. For the treatment of patients with local failure, the disease should be diagnosed more carefully than untreated disease. The disease that has recurred after radiation therapy may be more likely to be salvaged by surgery, however, the disease that has developed after surgery may have a limited indication for re-surgery.

  2. Targeting Btk with ibrutinib inhibit gastric carcinoma cells growth

    2016-01-01

    Bruton’s tyrosine kinase (Btk) is a member of the Tec-family non-receptor tyrosine kinases family. It has previously been reported to be expressed in B cells and has an important role in B-cell malignancies. While the roles of Btk in the pathogenesis of certain B-cell malignancies are well established, the functions of Btk in gastric carcinoma have never been investigated. Herein, we found that Btk is over-expressed in gastric carcinoma tissues and gastric cancer cells. Knockdown of Btk expression selectively inhibits the growth of gastric cancer cells, but not that of the normal gastric mucosa epithelial cell, which express very little Btk. Inhibition of Btk by its inhibitor ibrutinib has an additive inhibitory effect on gastric cancer cell growth. Treatment of gastric cancer cells, but not immortalized breast epithelial cells with ibrutinib results in effective cell killing, accompanied by the attenuation of Btk signals. Ibrutinib also induces apoptosis in gastric carcinoma cells as well as is a chemo-sensitizer for docetaxel (DTX), a standard of care for gastric carcinoma patients. Finally, ibrutinib markedly reduces tumor growth and increases tumor cell apoptosis in the tumors formed in mice inoculated with the gastric carcinoma cells. Given these promising preclinical results for ibrutinib in gastric carcinoma, a strategy combining Btk inhibitor warrants attention in gastric cancer. PMID:27508020

    Resistance is one limitation of sorafenib in the treatment of hepatocellular carcinoma (HCC). Insulin-like growth factor-1 receptor (IGF-1R) is involved in cancer cell proliferation. To assess the potential synergistic antitumor effects of picropodophyllin (PPP), an IGF-1R inhibitor, HLF and PLC/PRL/5, HCC cells were treated with PPP alone or PPP in combination with sorafenib, a multikinase inhibitor. Normal human umbilical vein endothelial cells (HUVECs) were also used to analyze the antiang...

  5. Carcinoma of the maxillary antrum treated by pre-operative radiotherapy or radical radiotherapy alone

    International Nuclear Information System (INIS)

    The results of pre-operative radical radiotherapy and subsequent maxillary resection are reported in 54 consecutive patients with carcinoma of the maxillary antrum treated at The Royal London Hospital from 1965 to 1989. The actuarial two and five year survivals were 50.3 per cent and 38.5 per cent respectively. Patients with adenocarcinomas fared better when compared with squamous and undifferentiated carcinomas (log rank p = <0.01). Undifferentiated carcinoma and involved regional lymph nodes were both very poor prognostic factors. In those patients who were either unfit for or refused maxillary resection, radical radiotherapy alone was still an effective treatment, with only a slight disadvantage in terms of local control and survival.

  7. Interaction of Stellate Cells with Pancreatic Carcinoma Cells

    International Nuclear Information System (INIS)

    Pancreatic cancer is characterized by its late detection, aggressive growth, intense infiltration into adjacent tissue, early metastasis, resistance to chemo- and radiotherapy and a strong “desmoplastic reaction”. The dense stroma surrounding carcinoma cells is composed of fibroblasts, activated stellate cells (myofibroblast-like cells), various inflammatory cells, proliferating vascular structures, collagens and fibronectin. In particular the cellular components of the stroma produce the tumor microenvironment, which plays a critical role in tumor growth, invasion, spreading, metastasis, angiogenesis, inhibition of anoikis, and chemoresistance. Fibroblasts, myofibroblasts and activated stellate cells produce the extracellular matrix components and are thought to interact actively with tumor cells, thereby promoting cancer progression. In this review, we discuss our current understanding of the role of pancreatic stellate cells (PSC) in the desmoplastic response of pancreas cancer and the effects of PSC on tumor progression, metastasis and drug resistance. Finally we present some novel ideas for tumor therapy by interfering with the cancer cell-host interaction

    Full Text Available Penile cancer shows variable incidence in different countries with a higher prevalence in developing countries. Squamous cell carcinoma represents the most common histologic type. The seventh decade of life corresponds to the mean age at diagnosis, but it is not an unusual diagnosis among young adults. Most cases present as “in situ” neoplasia or loco regional disease; however, systemic disseminated disease occurs via lymphatic and/or hematogeneous routes. The lymph nodes, liver, and lungs are the most frequently involved sites whereas the heart constitutes an exceptional and atypical site for penile cancer metastases. We report a case of a 79-year-old patient who presented a metastatic squamous cell carcinoma of the penis with intracardiac dissemination. The patient had a past history of cardiomyopathy, which required an artificial cardiac pacemaker implantation. He had been treated 1 year before with a partial penectomy but was admitted for emasculation due to the cancer relapse. During the postoperative period, he experienced sudden respiratory distress and died. The autopsy findings showed metastatic disease into the cardiac right chambers, pulmonary tumoral thrombi, and pulmonary hilar involvement. The authors call attention to the possibility of the presence of pacing leads, cardiomyopathy and the altered low blood flow in the right chambers, as predisposing factors for the tumoral seeding in this case.

    Anal squamous cell carcinoma (ASCC) is a rare, HPV-associated malignancy typically diagnosed in early stages and definitively treated with chemoradiation. In situations where patients exhibit metastatic or recurrent disease, treatment options are severely limited. In this study, molecular alterations were identified that could be used to aid in therapeutic decisions for patients with metastatic or recurrent anal squamous cell carcinoma. Specimens from patients with this cancer were tested via a multiplatform profiling service (Caris Life Sciences, Phoenix, AZ) consisting of gene sequencing, protein expression by immunohistochemistry, and gene amplification with in situ hybridization. Utilizing these techniques, novel treatment strategies that could be explored were identified, including potential benefit with anti-EGFR therapies, immune checkpoint inhibitors, topoisomerase inhibitors, and taxanes. The frequency of overexpression of proteins that mark resistance to chemotherapeutic drugs, such as MRP1 (chemotherapy efflux pump), ERCC1 (resistance to platinum-based chemotherapy), and thymidylate synthase (resistance to fluoropyrimidines) were also identified, suggesting a lack of benefit. This multiplatform strategy could be explored for its potential to generate a personalized treatment selection for patients with advanced ASCC, provide a guide for future therapeutic development for this cancer, and be extended to other rare cancer types as well.

    An eight-year-old, neutered male Burmese cat presented with five days vomiting and anorexia. Physical examination, clinical pathology and diagnostic imaging findings suggested a perirenal pseudocyst. After partial resection of the perirenal capsule clinical signs temporarily resolved, but the cat was euthanased 34 days postoperatively as a result of seizures and recurrence of vomiting. Postoperative histopathology showed neoplastic transitional cells within and lining the resected perirenal capsule; a diagnosis of transitional cell carcinoma was confirmed post-mortem. To the authors' knowledge, this is the first report of this presentation of transitional cell carcinoma. Transitional cell carcinoma should be a differential diagnosis for the aetiology of perirenal pseudocyst. PMID:17784930

  12. Inflammatory Cell Distribution in Primary Merkel Cell Carcinoma

    International Nuclear Information System (INIS)

    Merkel cell carcinoma (MCC) is an aggressive poorly differentiated neuroendocrine cutaneous carcinoma associated with older age, immunodeficiency and Merkel cell polyomavirus (MCPyV) integrated within malignant cells. The presence of intra-tumoural CD8+ lymphocytes reportedly predicts better MCC-specific survival. In this study, the distribution of inflammatory cells and properties of CD8+ T lymphocytes within 20 primary MCC specimens were characterised using immunohistochemistry and multicolour immunofluorescent staining coupled to confocal microscopy. CD8+ cells and CD68+ macrophages were identified in 19/20 primary MCC. CD20+ B cells were present in 5/10, CD4+ cells in 10/10 and FoxP3+ cells in 7/10 specimens. Only two specimens had almost no inflammatory cells. Within specimens, inflammatory cells followed the same patchy distribution, focused at the edge of sheets and nodules and, in some cases, more intense in trabecular areas. CD8+ cells were outside vessels on the edge of tumour. Those few within malignant sheets typically lined up in fine septa not contacting MCC cells expressing MCPyV large T antigen. The homeostatic chemokine CXCL12 was expressed outside malignant nodules whereas its receptor CXCR4 was identified within tumour but not on CD8+ cells. CD8+ cells lacked CXCR3 and granzyme B expression irrespective of location within stroma versus malignant nodules or of the intensity of the intra-tumoural infiltrate. In summary, diverse inflammatory cells were organised around the margin of malignant deposits suggesting response to aberrant signaling, but were unable to penetrate the tumour microenvironment itself to enable an immune response against malignant cells or their polyomavirus

  16. BRCC3 acts as a prognostic marker in nasopharyngeal carcinoma patients treated with radiotherapy and mediates radiation resistance in vitro

    International Nuclear Information System (INIS)

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

    Full Text Available Basal cell carcinoma originates from pluripotent cells of basal layer of epiderm, external covering of hair follicles, sebaceous glands or other skin adnexa. It is characterized by local infiltrating and sometimes destructive growth. There are several types of basal cell carcinomas that may be manifested in over 12 clinical forms. Surgical treatment depends to a large extent on the histological type, localization and its clinical manifestation. The analysis included 250 patients of both gender and different age, operated for basal cell carcinoma. Clinical characteristics of basal cell carcinoma and the width of the excision were described. It was concluded that the width of the excision of basal cell cancer was in relation to histological type. .

    Treatment of renal cell carcinoma has evolved considerably over the last few years. While total nephrectomy is necessary at times, nephron-sparing surgery, with a goal of renal function preservation, should always be considered. Although open partial nephrectomy is considered the gold standard approach for nephron-sparing surgery, laparoscopic- or robotic-assisted techniques allow urologists to perform renal surgery less invasively, with excellent long-term oncological outcomes. Cryotherapy and radiofrequency ablation are less invasive management approaches for carefully selected patients with small renal masses. Active surveillance should be considered in elderly or patients who are unfit for surgery. Ultimately, the method chosen for management of a renal mass is an informed decision made by the physician and patient. PMID:26892144

    Full Text Available Basal cell carcinoma (BCC is the most frequent non-melanoma skin cancer. Only 5-15% of BCC cases can be found in patients aged 20-40 years (so-called early onset. The early onset BCC is characterized by active and aggressive tumour growth, clinically presenting in most of the cases as a morpheaform, locally infiltrating or recurrent BCC. Despite the advances in the study of the pathogenesis of this tumour, surgery remains the most used, most effective and most suitable treatment modality. We describe a case of a 39-year-old woman who developed an early onset BCC of the nasolabial fold. After the subsequent surgical excision an excellent cosmetic result was achieved.

    This review provides an overview of the incidence of renal cell carcinoma (RCC) and a summary of the most commonly associated risk factors. A literature review was performed with a focus on recent studies with a high level of evidence (large prospective cohort studies and meta-analyses). The incidence rate of RCC varies globally, with the rate rising rapidly in more developed regions, demonstrating the effects of increased use of diagnostic imaging and prevalence of modifiable risk factors. Based on the current evidence, cigarette smoking, obesity, and hypertension are the most well-established risk factors for sporadic RCC worldwide. Acquired cystic kidney disease is also a significant risk factor, specifically in dialysis patients. There is increasing evidence for an inverse association between RCC risk and moderate alcohol consumption. Certain analgesics and occupational exposure have been linked to an increased risk of RCC, although data are limited. Diets rich in fruits and vegetables may provide a protective effect.

    Targeted therapies have fundamentally altered the therapy of metastatic renal cell carcinoma (mRCC). Sunitinib today is an internationally recommended reference standard in first-line therapy; other drugs such as Temsirolimus, Everolimus, Bevacizumab (in combination with Interferon-alpha) and Sorafenib are part of the therapeutic arsenal. Practitioners thus have now more and better therapeutic options at hand, leading to a significantly improved prognosis for mRCC patients. Numerous ongoing research activities aim at the improvement of the benefits of the new compounds in the metastatic situation or application earlier in the course of the disease. Key aspects of future development in RCC are the optimization of the current therapy options by developing new targeted therapies, the search for the best combinations and sequences including the role of nephrectomy and the assessment in the adjuvant or neo-adjuvant setting. The following contribution provides an overview of ongoing studies, thus giving insight into the future therapy of RCC. PMID:20164673

    Full Text Available Abstract Background The head and neck/oral squamous cell carcinoma (HNOSCC is a diverse group of cancers, which develop from many different anatomic sites and are associated with different risk factors and genetic characteristics. The oral tongue squamous cell carcinoma (OTSCC is one of the most common types of HNOSCC. It is significantly more aggressive than other forms of HNOSCC, in terms of local invasion and spread. In this study, we aim to identify specific transcriptomic signatures that associated with OTSCC. Results Genome-wide transcriptomic profiles were obtained for 53 primary OTSCCs and 22 matching normal tissues. Genes that exhibit statistically significant differences in expression between OTSCCs and normal were identified. These include up-regulated genes (MMP1, MMP10, MMP3, MMP12, PTHLH, INHBA, LAMC2, IL8, KRT17, COL1A2, IFI6, ISG15, PLAU, GREM1, MMP9, IFI44, CXCL1, and down-regulated genes (KRT4, MAL, CRNN, SCEL, CRISP3, SPINK5, CLCA4, ADH1B, P11, TGM3, RHCG, PPP1R3C, CEACAM7, HPGD, CFD, ABCA8, CLU, CYP3A5. The expressional difference of IL8 and MMP9 were further validated by real-time quantitative RT-PCR and immunohistochemistry. The Gene Ontology analysis suggested a number of altered biological processes in OTSCCs, including enhancements in phosphate transport, collagen catabolism, I-kappaB kinase/NF-kappaB signaling cascade, extracellular matrix organization and biogenesis, chemotaxis, as well as suppressions of superoxide release, hydrogen peroxide metabolism, cellular response to hydrogen peroxide, keratinization, and keratinocyte differentiation in OTSCCs. Conclusion In summary, our study provided a transcriptomic signature for OTSCC that may lead to a diagnosis or screen tool and provide the foundation for further functional validation of these specific candidate genes for OTSCC.

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

    Directory of Open Access Journals (Sweden)

    Charlotte T A H Wetzels

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

Liver CSCs have emerged as an important therapeutic target against HCC. Numerous surface markers for liver CSCs have been identified, and include CD133, CD90, CD44, CD13, and epithelial cell adhesion molecules. These surface markers serve not only as tools for identifying and isolating liver CSCs but also as therapeutic targets for eradicating these cells. In studies of animal models and large-scale genomic analyses of human HCC samples, many signaling pathways observed in normal stem cells have been found to be altered in liver CSCs, which accounts for the stemness and aggressive behavior of these cells. Antibodies and small molecule inhibitors targeting the signaling pathways have been evaluated at different levels of preclinical and clinical development. Another strategy is to promote the differentiation of liver CSCs to less aggressive HCC that is sensitive to conventional chemotherapy. Disruption of the tumor niche essential for liver CSC homeostasis has become a novel strategy in cancer treatment. To overcome the challenges in developing treatment for liver CSCs, more research into the genetic makeup of patient tumors that respond to treatment may lead to more effective therapy. Standardization of HCC CSC tumor markers would be helpful for measuring the CSC response to these agents. Herein, we review the current strategies for developing treatment to eradicate liver CSCs and to improve the outcome for patients with

  18. Leptomeningeal carcinomatosis from squamous cell carcinoma of the supraglottic larynx

    International Nuclear Information System (INIS)

    Leptomeningeal carcinomatosis is an uncommon but devastating form of metastatic spread. To our knowledge, only 16 cases originating from a head and neck cancer have been reported. We describe the first case of a patient with leptomeningeal carcinomatosis arising from a laryngeal squamous cell carcinoma. Shortly after completing treatment for an advanced supraglottic laryngeal cancer, this 63-year-old man presented with lower limb neurological symptoms and signs. Radiological and cytological evidence of leptomeningeal carcinomatosis of the distal spinal canal was identified. He was treated with intrathecal methotrexate and palliative radiotherapy. Although his pain improved, his lower limb weakness worsened. He died 3 weeks after completing radiotherapy. Presumed mode of spread was via the haematogenous route. The natural history and management of leptomeningeal carcinomatosis are discussed. Clinicians should be aware of the uncommon possibility of leptomeningeal carcinomatosis in a patient presenting with an appropriate constellation of symptoms and signs, and a past history of cancer.

  19. Long term survivors with small cell carcinoma of the lung

    International Nuclear Information System (INIS)

    A retrospective study was done of all patients who survived 2 years or more with small cell carcinoma (SCC) of the lung. The study period was 1970 to 1978 and patients with either local or metastatic disease were included. Pathology review documented 17 patients with an unequivocal diagnosis of SCC surviving 2 years or more. The important conclusions of this study are: (1) Local treatment (either surgery or radiation therapy) was an important part of therapy for long term survival; (2) Local tumor control in the lung was superior in those patients treated with surgery or high dose lung irradiation (>4800 rad) compared to patients with low dose lung irradiation (<3500 rad); and (3) 33% of the patients who were without evidence of disease at 2 years eventually relapsed, implying that even a 2 year follow-up is inadequate to fully assess treatment efficacy

    Continuous follow-up of 244 patients treated for primary invasive squamous cell carcinoma of the vulva during a 20-year period (1960-1979) resulted in the detection of recurrent (or persistent) disease in 60 cases. Forty-one of these cases developed local or regional recurrence, or both, later than six months after treatment, and an analysis of the result of retreatment in this group is presented. Twenty-nine had local recurrences, nine regional metastases and three local recurrences and regional metastases. The treatment technique for local recurrences was surgery, in a few cases combined with irradiation and chemotherapy. In approximately one-third of the cases, this treatment resulted in long-term or permanent cure. In cases of regional metastases the prognosis was often extremely poor, but treatment normally gave good palliation although of short duration. (orig.)

    Full Text Available Squamous cell carcinoma is the most common malignant neoplasm of the Oral Cavity, usually affecting individuals over 50 years of age. It rarely occurs in patients who are less than 40 years old (0.4-5.5%. However, since it is so rare, when cases occur they are often misdiagnosed and inappropriately treated leading to delay in definitive treatment. This report describes a case of squamous cell carcinoma, involving the posterolateral border of the tongue of a 19-year-old female patient, with no deleterious habits usually associated with oral cancer. This report focuses on the etiological factors and prognosis related to the case. Additionally, a brief literature review regarding squamous cell carcinoma in young patients is also included.

    Purpose: To compare clinical behaviors and treatment outcomes between patients with squamous cell carcinoma (SCC) and adenocarcinoma/adenosquamous carcinoma (AC/ASC) of the cervix treated with radical hysterectomy (RH) and adjuvant radiotherapy (RT) or concurrent chemoradiotherapy (CCRT). Methods and Materials: A total of 318 Stage IB-IIB cervical cancer patients, 202 (63.5%) with SCC and 116 (36.5%) with AC/ASC, treated by RH and adjuvant RT/CCRT, were included. The indications for RT/CCRT were deep stromal invasion, positive resection margin, parametrial invasion, or lymph node (LN) metastasis. Postoperative CCRT was administered in 65 SCC patients (32%) and 80 AC/ASC patients (69%). Patients with presence of parametrial invasion or LN metastasis were stratified into a high-risk group, and the rest into an intermediate-risk group. The patterns of failure and factors influencing survival were evaluated. Results: The treatment failed in 39 SCC patients (19.3%) and 39 AC/ASC patients (33.6%). The 5-year relapse-free survival rates for SCC and AC/ASC patients were 83.4% and 66.5%, respectively (p = 0.000). Distant metastasis was the major failure pattern in both groups. After multivariate analysis, prognostic factors for local recurrence included younger age, parametrial invasion, AC/ASC histology, and positive resection margin; for distant recurrence they included parametrial invasion, LN metastasis, and AC/ASC histology. Compared with SCC patients, those with AC/ASC had higher local relapse rates for the intermediate-risk group but a higher distant metastasis rate for the high-risk group. Postoperative CCRT tended to improve survival for intermediate-risk but not for high-risk AC/ASC patients. Conclusions: Adenocarcinoma/adenosquamous carcinoma is an independent prognostic factor for cervical cancer patients treated by RH and postoperative RT. Concurrent chemoradiotherapy could improve survival for intermediate-risk, but not necessarily high-risk, AC/ASC patients.

    International Nuclear Information System (INIS)

    Objective: To detect the expression of protein kinase C (PKC) in multidrug resistant cells of colorectal carcinoma after ionizing irradiation and observe the effect of PKC on occurrence and development of the multidrug resistant. Methods: The effect of PKC on multidrug resistant HCG-8 cells of colorectal carcinoma after treated with X-ray was detected by indirect immunofluorescence technique and flow cytometry. Results: Compared with sham- irradiation group, the positive percentage of PKC was increased significantly (P<0.05) after HCT-8 cells were treated with 2 Gy X-ray, the positive percentages of PKC were increased insignificantly after HCT-8 cells were treated with low dose (50, 100 mGy) before high dose of irradiation, the increasing of positive percentage of PKC in the group of 200 mGy + 2 Gy was significant (P<0.05). Compared with the group only treated with high dose of irradiation, the positive percentage of PKC in the group of 100 mGy + 2 Gy was decreased significantly (P< 0.05). Conclusion: High dose of ionizing irradiation can increase the expression of PKC in colorectal carcinoma significantly, reversely when HCT-8 cells are pretreated with low dose before high dose there is no additional increase of PKC expression.

  12. Bone Metastasis from Renal Cell Carcinoma

    About one-third of patients with advanced renal cell carcinoma (RCC) have bone metastasis that are often osteolytic and cause substantial morbidity, such as pain, pathologic fracture, spinal cord compression and hypercalcemia. The presence of bone metastasis in RCC is also associated with poor prognosis. Bone-targeted treatment using bisphosphonate and denosumab can reduce skeletal complications in RCC, but does not cure the disease or improve survival. Elucidating the molecular mechanisms of tumor-induced changes in the bone microenvironment is needed to develop effective treatment. The “vicious cycle” hypothesis has been used to describe how tumor cells interact with the bone microenvironment to drive bone destruction and tumor growth. Tumor cells secrete factors like parathyroid hormone-related peptide, transforming growth factor-β and vascular endothelial growth factor, which stimulate osteoblasts and increase the production of the receptor activator of nuclear factor κB ligand (RANKL). In turn, the overexpression of RANKL leads to increased osteoclast formation, activation and survival, thereby enhancing bone resorption. This review presents a general survey on bone metastasis in RCC by natural history, interaction among the immune system, bone and tumor, molecular mechanisms, bone turnover markers, therapies and healthcare burden.

  13. Comparative study of MRI appearances in clear cell renal cell carcinoma, papillary renal cell carcinoma and chromophobe renal cell carcinoma

    International Nuclear Information System (INIS)

    Objective: To investigate the differential diagnostic features of subtypes of renal cell carcinoma (RCC) using dynamic contrast-enhanced MRI(DCE-MRI). Methods: The MRI appearances of 77 RCCs, including 55 clear cell RCCs (CCRCC), 14 papillary RCCs (PRCC) and 8 chromophobe RCCs (CRCC), were retrospectively analyzed and compared with findings of pathology. DCE-MRI was conducted in each case after intravenous administration of contrast agent. Region of interest measurements (cortical, nephrographic and delayed Phases) of signals within tumor and uninvolved renal cortex were used to calculate percentage signal intensity change and tumor-to-cortex enhancement index, and the data was analyzed by AVONA and t test. Results: On unenhanced and enhanced MRI, most CRCCs showed homogeneous signal (7/8). CCRCC and PRCC often show inhomogeneous signal with necrosis (36/55, 7/14). Hemorrhage and cystic degeneration were often found in PRCC (9/14). On the cortical, nephrographic and delayed phase images, CCRCCs showed greater signal intensity change [(296.15± 60.27)%, (236.33±58.31)% and (216.83±46.72)%, respectively than PRCCs (79.70±18.84)%, (122.81±27.35)% and (117.55±20.63)%, respectively], and CRCCs showed intermediate change [(119.56±40.76)%, (163.06±33.91)% and (179.72±32.89)%, respectively]. A phenomenon of quick staining and quick fainting was observed in CCRCCs. Both of CRCCs and PRCCs showed delayed enhancement. The tumor-to-cortex enhancement index at the cortical, nephrographic and delayed phases was highest for CCRCCs (1.26±0.34, 0.92±0.23 and 0.76±0.14, respectively), lowest for PRCCs (0.33±0.12, 0.41±0.23 and 0.35±0.11, respectively), and intermediate for CRCCs (0.54±0.10, 0.62±0.15 and 0.69±0.12, respectively, P<0.01). The degree of enhancement was significantly different among the 3 subtypes at the every contrast enhanced phase (F= 940.931, 124.515 and 38.194, P<0.01), so was the tumor-to-cortex enhancement index (F=798.625, 78.308 and 73.699, P

    Full Text Available Basal cell and squamous cell carcinoma of skin are common tumors which can be easily distinguished on hematoxylin and eosin stained sections, but basosquamous carcinoma is a controversial entity. The aim of our study was to distinguish basal cell carcinoma and basosquamous carcinoma using Ber-EP4, immunohistochemically in 52 skin tumors. Twenty basal cell carcinomas, 20 squamous cell carcinomas, 10 basosquamous carcinomas and 2 collision tumors of the skin were stained with Ber-EP4 immunohistochemically. All basal cell carcinomas were stained strongly and diffusely with Ber-EP4, whereas squamous cell carcinomas were not, and basosquamous carcinomas were partially stained. Our results suggest that, distinction of basal cell carcinoma and basosquamous carcinoma can be achieved with routine immunohistochemical Ber-EP4 staining.

    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.

  4. Local therapy for small cell carcinoma of the cervix

    International Nuclear Information System (INIS)

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

    2011-01-01

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

    Natural substances have been attracted several researchers in the recent years, because of its potential antioxidant, anti-inflammatory and anti-cancer properties. We have investigated the effect of carnosine on cell viability, apoptosis, DNA damage, reactive oxygen species (ROS) and caspase 3 enzyme expression in human cervical carcinoma and Madin-Darby Kidney Cells (MDCK) cells. Carnosine inhibited cancer cell growth up to 23%. ROS level was increased up to 30 and 31% in MDCK and HeLa cells respectively. Tunnel assay showed 42 and 14% of positive apoptotic cells in cancer and normal cells respectively. The alteration in mitochondrial and nuclear morphology was determined. The extended lace-like network of normal mitochondria found in control cells. Carnosine treatment significantly altered the mitochondrial morphology of normal cervical carcinoma cell. Mitochondria were condensed clump structures in carnosine treated cancer cells. Carnosine reduced the number of colonies of cervical carcinoma cells. Caspase 3 expression was corresponded to the appearance of immunofluorescence in the cytoplasm. Caspase 3 expression was gradually increased in cervical carcinoma cells. In Silico, docking study was performed to recognize the binding activity of carnosine against a subunit of the caspase 3, and carnosine was able to bind to the drug binding pocket of caspase 3. The glide energy is -5.2 kcal/mol, suggesting the high binding affinity of carnosine to caspase 3. Taking all these data together, the natural dipeptide L-carnosine could be a suitable antiproliferative agent in cervical carcinoma cells. Copyright © 2016 John Wiley & Sons, Ltd. PMID:27000946

  10. Peripheral T-lymphocytes and delayed hypersensitivity in surgically and radiologically treated patients with early stages of larynx-carcinoma

    International Nuclear Information System (INIS)

    122 patients with squamous-cell-carcinoma of the larynx (T1-stage) were examined after surgical or radiological treatment. None of these patients showed evidence of tumor recurrence. Peripheral T-lymphocytes and delayed hypersensitivity were studied in all these patients. According to their treatment, the patients were allotted into three groups and compared with a control group, consisting of 20 patients with nonneoplastic head- and neck-disease. The main finding was a significant decrease in the peripheral T-lymphocytes in surgically- or radiologically-treated patients with a squamous-cell-carcinoma of the larynx (T1-stage). This reduction of T-cells must be interpreted as a congenital or acquired defect of the immunocompetent system. In about half of the control cases the DNCB-tests showed no evidence of delayed hypersensitivity. In view of these results and those reported in the literature, the test should be used critically. In contrast to our earlier findings, where patients received radiotherapy over large areas including big vessels, radiation over a smaller, localised area does not lead to a significant depression of peripheral T-lymphocytes.

  14. Merkel Cell Carcinoma in Immunosuppressed Patients

    International Nuclear Information System (INIS)

    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

    AIM: To investigate the density of mast cells (MCs) in human hepatocellular carcinoma (HCC), and to determine whether the MCs density has any correlations with histopathological grading, staging or some baseline patient characteristics.METHODS: Tissue sections of 22 primary HCCs were histochemically stained with toluidine blue, in order to be able to quantify the MCs in and around the neoplasm using a computer-assisted image analysis system. HCC was staged and graded by two independent pathologists. To identify the sinusoidal capillarisation of each specimen 3μm thick sections were histochemically stained with sirius red, and semi-quantitatively evaluated by two independent observers. The data were statistically analysed using Spearman′s correlation and Student′s t-test when appropriate.RESULTS: MCs density did not correlate with the age or sex of the patients, the serum alanine aminotransferase (ALT) or aspartate aminotransferase (AST) levels, or the stage or grade of the HCC. No significant differences were found between the MCs density of the patients with and without hepatitis C virus infection, but they were significantly higher in the specimens showing marked sinusoidal capillarisation.CONCLUSION: The lack of any significant correlation between MCs density and the stage or grade of the neoplastic lesions suggests that there is no causal relationship between MCs recruitment and HCC. However, as capillarisation proceeds concurrently with arterial blood supply during hepatocarcinogenesis, MCs may be considered of primary importance in the transition from sinusoidal to capillary-type endothelial cells and the HCC growth.

  17. Osteoblastic bone metastases from renal cell carcinoma

    International Nuclear Information System (INIS)

    RCC accounts for only 2–3% of all cancers. Due to its’ non-specific symptoms disease is often diagnosed in advanced stage. Disseminated RCC frequently produces bone metastases that are almost always highly destructive, hyper vascularized and purely osteolytic. In this article we describe a case of a 71-year old male patient with disseminated osteoblastic bone metastases from renal cell carcinoma (RCC), and present a short review of published literature reporting cases of osteoblastic bone metastases from RCC. Our patient presented with thoracic pain aggravated by movement. He was diagnosed with predominantly osteoblastic bone metastases in the skeleton of thoracic and lumbar vertebra along with metastases in iliac bones, ribs, humerus and clavicles. Initially, origin of bone metastases was unknown, but later a small tumor in patient’s right kidney was identified. Microscopic evaluation of the open bone biopsy showed clear cell RCC with sarcomatoid differentiation. Although, due to its’ rarity, RCC is not included in the primary differential diagnosis in patients with osteoblastic metastases, such rare cases suggest that RCC may be considered in the diagnosis when there no other primary tumor is found

The pathogenesis of MCC is not well understood, and despite a recent plethora of mutational analyses, we have yet to find a set of signature mutations implicated in the majority of cases. Mutations, including TP53, Retinoblastoma and PIK3CA, have been documented in subsets of patients. Other mechanisms are also likely at play, including infection with the Merkel cell polyomavirus in a subset of patients, dysregulated immune surveillance, epigenetic alterations, aberrant protein expression, posttranslational modifications and microRNAs. In this review, we summarize what is known about MCC genetic mutations and chromosomal abnormalities, and their clinical significance. We also examine aberrant protein function and microRNA expression, and discuss the therapeutic and prognostic implications of these findings. Multiple clinical trials designed to selectively target overexpressed oncogenes in MCC are currently underway, though most are still in early phases. As we accumulate more molecular data on MCC, we will be better able to understand its pathogenic mechanisms, develop libraries of targeted therapies, and define molecular prognostic signatures to enhance our clinicopathologic knowledge.

    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 Abstract Introduction Pulmonary metastasis presenting as lymphangitic carcinomatosis arising from squamous cell carcinoma (SCC of the cervix is a rare event. Poorly represented in the literature, this event is associated with a difficulty in accurate diagnosis, b grave prognosis, and the c lack of recognized predisposing risk factors. Case Report A 50 year-old female presented at our practice with a three-month history of a productive cough associated with dyspnoea and shortness of breath. A chest x-ray and computed tomography (CT scan revealed multiple bilateral patchy areas with subsegmental atelectasis in both lungs which was investigated with a bronchoscopy, left thoracoscopy, and a left lung biopsy. Pathological examination of the wedge biopsy of the left upper lobe revealed neoplastic sheets of cell disturbed along the septal vessels, perivascular/peribronchial lymphatics, and the subpleural lymphatics. This lymphangitic carcinomatosis was confirmed to be metastatic from SCC of the cervix that had been diagnosed and treated two years ago. She was treated with systemic Carbo/Taxol chemotherapy and corticosteroids as a palliative measure. Despite temporary improvement, she died 13 months later. Conclusion Pulmonary lymphangitic carcinomatosis is a rare manifestation of metastatic SCC of the cervix. As clinical presentations including radiographic imaging mimics other pulmonary entities, accurate diagnosis remains a challenge. Increased clinical awareness of such patterns of metastases in cervical cancer supported by accurate pathological diagnosis is imperative to guide appropriate therapy in these patients.

  19. Elevated cyclooxygenase-2 expression correlates with diminished survival in carcinoma of the cervix treated with radiotherapy

    International Nuclear Information System (INIS)

    Purpose: The purpose of this study was to examine the relationship between overall survival and prognostic factors in carcinoma of the cervix treated with radiation therapy. A clinicopathologic study was performed on 24 patients. Methods and Materials: Formalin-fixed, paraffin-embedded tumor biopsies were stained for Cyclooxygenase-2 (COX-2), Topoisomerase I, Topoisomerase II, and p53. Clinical factors such as stage, grade, tumor size, pre- and post-treatment hemoglobin level, and radiotherapy dose were also evaluated. Results: Median follow-up was 75 months for living patients. The only immunohistochemical or clinical factor that was associated with improved survival was decreased COX-2 distribution staining. High COX-2 distribution staining was associated with decreased overall survival (p=0.021) and decreased disease-free survival (p=0.015) by log-rank comparison of Kaplan-Meier survival curves. The 5-year overall survival rates for tumors with low vs. high COX-2 distribution values were 75% and 35%, respectively. COX-2 staining intensity was found to correlate positively with tumor size (p=0.022). Conclusion: These findings indicate that increased expression of COX-2 portends a diminished survival in patients with invasive carcinoma of the cervix treated with radiotherapy. Because COX-2 is an early-response gene involved in angiogenesis and inducible by different stimuli, these data may indicate opportunity to intervene with specific inhibitors of COX-2 in carcinoma of the cervix

    Objectives. The aim was to compare demographics and pathological features of bladder carcinoma treated in a urology unit with findings of previous studies done in Sri Lanka. Materials and Methods. Data of newly diagnosed patients with bladder cancer in a tertiary referral centre from 2011 to 2014 were analysed. Data on bladder cancers diagnosed from 1993 to 2014 were obtained from previous publications and Sri Lanka Cancer Registry. Results. There were 148 patients and mean age was 65 years. Male to female ratio was 4.1 : 1. Urothelial carcinoma (UC) was found in 89.2% of patients. Muscle invasion was noted in 35% of patients compared to 48.4% two decades ago. In patients with UC, 16.5% were found to have pT1 high grade tumour. It was 5.3% from 1993 to 2000. Pure squamous cell carcinoma was found in 8.1% of patients while primary or de novo carcinoma in situ (not associated with high grade pT1 tumours) was seen in one patient only. Conclusions. The percentage of squamous carcinoma is higher among Sri Lankan patients while primary carcinoma in situ is a rarity. The percentage of muscle invasive disease has decreased while the percentage of pT1 high grade tumours has increased during the last two decades in Sri Lanka. PMID:26884756

    The aim of this study was to compare the prevalence of human papillomavirus (HPV) infection in laryngeal squamous cell carcinoma using two methods: PCR-DNA enzyme immunoassay (PCR/DEIA) and immunohistochemistry (IHC) for detection of HPV in specimens of laryngeal squamous cell carcinoma and to correlate the presence of HPV with the epidemiological and clinicopathological features of recurrence and survival. HPV DNA was amplified from 93 paraffin-embedded laryngeal squamous cell carcinoma tissue specimens by the short PCR fragment (SPF 10) primer set using PCR/DNA method. HPV detection using monoclonal anti-human papilloma virus antibodies Clone K1H8 for IHC reaction was performed on 130 specimens. HPV was identified in 35.5% of patients with laryngeal squamous cell carcinoma using PCR/DEIA and 27.7% using IHC. There was no statistically significant association between the presence of HPV and the epidemiological and clinicopathological features and recurrence. There was no statistically significant association between the presence of HPV and overall survival nor disease specific survival. Statistically significant correlation between HPV detection using PCR/DEIA technique and IHC technique was found. The presence of HPV infection in 27.7% and 38.9% of the patients suggests a possible role in the etiology of laryngeal squamous cell carcinoma. The SPF(10) PCR/DEIA technique is the most accurate method for detection of HPV in laryngeal squamous cell carcinoma. PMID:20419817

    Autophagy is evolutionarily conservative in eukaryotic cells that engulf cellular long-lived proteins and organelles, and it degrades the contents through fusion with lysosomes, via which the cell acquires recycled building blocks for the synthesis of new molecules. In this study, we revealed that peiminine induces cell death and enhances autophagic flux in colorectal carcinoma HCT-116 cells. We determined that peiminine enhances the autophagic flux by repressing the phosphorylation of mTOR through inhibiting upstream signals. Knocking down ATG5 greatly reduced the peiminine-induced cell death in wild-type HCT-116 cells, while treating Bax/Bak-deficient cells with peiminine resulted in significant cell death. In summary, our discoveries demonstrated that peiminine represses colorectal carcinoma cell proliferation and cell growth by inducing autophagic cell death. - Highlights: • Peiminine induces autophagy and upregulates autophagic flux. • Peiminine represses colorectal carcinoma tumor growth. • Peiminine induces autophagic cell death. • Peiminine represses mTOR phosphorylation by influencing PI3K/Akt and AMPK pathway.

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

    Small cell carcinoma of the bladder is a rare, aggressive, poorly differentiated neuroendocrine neoplasm accounting for only 0.3-0.7% of all bladder tumors. Since the tumor is very rare, pathogenesis is uncertain. Small cell carcinomas of the urinary bladder are mixed with classic urothelial carcinomas or adenocarcinomas of the bladder in 68% cases, making pure primary small cell carcinoma even a rarer entity. The unknown etiology and natural history of small cell carcinoma of the urinary bla...

  7. Prognostic factors for oral tongue carcinoma treated with intra-oral cone electron beam irradiation

    International Nuclear Information System (INIS)

    Twenty-five patients with squamous cell carcinoma of the oral tongue were treated with intra-oral cone electron beam irradiation (IOC) during the period from 1985 to 1995. We analyzed the prognostic factors for local control and complications. IOC was applied for T1 (16 cases) and T2 (9 cases) tumors. Hypofractionation was used for IOC (20, 10, or 8 Gy/fr, 1f/ wk). The total dose delivered ranged from 40 Gy to 78 Gy. Radiation dose homogenization was done through calculation of the normalized total dose (NTD) for α/β=10 (tumor) and α/β=3 (late normal tissue). The two-year local control rates for T1 and T2 were 80.4% and 77.8%, respectively. The two-year local control rates for patients whose overall treatment time (OTT) was ≤ 28 days (n=16) was 100% vs. 41.7% for patients whose OTT was >28 days (n=9) (p=0.002). Multivariate analysis was applied to identify possible prognostic factors for local control, OTT (p=0.02) was the only variable that significantly influenced local control. The incidence of radiation ulcer was 33.3% (7/21). Significant indicators of ulceration were fraction size (>>10 Gy) and NTD (α/β=3) (>>130 Gy) (p<0.05). These results indicate that prolonged OTT was the major reason for the failure of IOC radiotherapy to control local disease and that the relatively high rate of ulceration was due to large fraction size and high NTD (α/β=3).

  8. Retrospective Analysis of Local Control and Cosmetic Outcome of 147 Periorificial Carcinomas of the Face Treated With Low-Dose Rate Interstitial Brachytherapy

    International Nuclear Information System (INIS)

    Purpose: Skin cancer is the most common malignancy in white populations. We evaluated the local cure rate and cosmetic outcome of patients with basal cell carcinoma (BCC) or squamous cell carcinoma (SCC) of the face treated with low-dose rate brachytherapy. Methods and Materials: Between February 1990 and May 2000, 147 facial carcinomas in 132 patients were treated by 192Ir wire implantation. Side effects of brachytherapy were noted. Follow-up was 2 years or more. Locoregional recurrence-free survival (LRFS) and overall survival were recorded. Group A included patients treated by primary brachytherapy, and Group B included those treated after recurrence. Results: A total of 121 carcinomas were BCCs (82.3%) and 26 were SCCs (17.7%); the median tumor size was 10 mm. Of the tumors, 86 (58.5%) were in men and 61 (41.5%) were in women; the median age was 71 years. Group A comprised 116 lesions (78.9%), and Group B, 31 (21.1%). There were 17 relapses (11.6%) after a median follow-up of 72 months: 12 local, 4 nodal, and 1 local and nodal. Locoregional-free survival was 96.6% at 2 years and 87.3% at 5 years. Five-year LRFS was 82.6% in men and 93.3% in women (p = 0.027). After adjustment for gender, LRFS was better after primary treatment than after recurrence (hasard ratio HR, 2.91; 95% confidence interval, 1.06-8.03; p = 0.039). Five-year LRFS was 90.4% for BCC and 70.8% for SCC (p = 0.03). There were no Grade 3 complications. Conclusions: Low-dose rate brachytherapy offers good local control and cosmetic outcome in patients with periorificial skin carcinomas, with no Grade 3 complications. Brchytherapy is more efficient when used as primary treatment.

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

    Various imaging modalities are available for the diagnosis, staging and response evaluation of patients with renal cell carcinoma(RCC). While contrast enhanced computed tomography(CT) is used as the standard of imaging for size, morphological evaluation and response assessment in RCC, a new functional imaging technique like perfusion CT(p CT), goes down to the molecular level and provides new perspectives in imaging of RCC. p CT depicts regional tumor perfusion and vascular permeability which are indirect parameters of tumor angiogenesis and thereby provides vital information regarding tumor microenvironment. Also response evaluation using p CT may predate the size criteria used in Response Evaluation Criteria in Solid Tumors, as changes in the perfusion occurs earlier following tissue kinase inhibitors before any actual change in size. This may potentially help in predicting prognosis, better selection of therapy and more accurate and better response evaluation in patients with RCC. This article describes the techniques and role of p CT in staging and response assessment in patients with RCCs.

    In an ongoing screen for DNA sequence variants that confer risk of cutaneous basal cell carcinoma (BCC), we conduct a genome-wide association study (GWAS) of 24,988,228 SNPs and small indels detected through whole-genome sequencing of 2,636 Icelanders and imputed into 4,572 BCC patients and 266,358 controls. Here we show the discovery of four new BCC susceptibility loci: 2p24 MYCN (rs57244888[C], OR=0.76, P=4.7 × 10−12), 2q33 CASP8-ALS2CR12 (rs13014235[C], OR=1.15, P=1.5 × 10−9), 8q21 ZFHX4 (rs28727938[G], OR=0.70, P=3.5 × 10−12) and 10p14 GATA3 (rs73635312[A], OR=0.74, P=2.4 × 10−16). Fine mapping reveals that two variants correlated with rs73635312[A] occur in conserved binding sites for the GATA3 transcription factor. In addition, expression microarrays and RNA-seq show that rs13014235[C] and a related SNP rs700635[C] are associated with expression of CASP8 splice variants in which sequences from intron 8 are retained.

    Renal cell carcinoma (RCC) is one of the ten most frequent solid tumors worldwide. Recent innovations in the treatment of metastatic disease have led to new therapeutic approaches being investigated in the adjuvant setting. Observation is the only current standard of care after radical nephrectomy, although there is evidence of efficacy of adjuvant use of vaccine among all the strategies used. This article aims to collect published experiences with systemic adjuvant approaches in RCC and to describe the results of past and ongoing phase III clinical trials in this field. We explored all the systemic treatments, including chemotherapy, immunotherapy and targeted drugs while alternative approaches have also been described. Appropriate selection of patients who would benefit from adjuvant therapies remains a crucial dilemma. Although the international guidelines do not actually recommend any adjuvant treatment after radical surgery for RCC, no conclusions have yet been drawn pending the results of the promising ongoing clinical trials with the target therapies. The significant changes that these new drugs have made on advanced disease outcome could represent the key to innovation in terms of preventing recurrence, delaying relapse and prolonging survival after radical surgery for RCC.

    Full Text Available El carcinoma de células escamosas de tiroides (CCET es un tumor infrecuente y agresivo. Su etiología es incierta. Ante la presencia de carcinoma escamoso en la glándula tiroides debe excluirse la posibilidad de infiltración de un tumor originado en una estructura adyacente o de metástasis de otros carcinomas. El tratamiento de elección es la cirugía radical. La mayoría de los pacientes fallecen antes del año debido a progresión local de la enfermedad. Presentamos el caso de un paciente con una masa tiroidea, con diagnóstico histológico de carcinoma escamoso (con inmunohistoquímca negativa para tiroglobulina, TTF1 y calcitonina y positiva para p63 y citok5. Los estudios clínicos, endoscópicos y radiológicos excluyeron otros sitios de origen de carcinoma escamoso. Fue tratado con quimio y radioterapia, falleciendo por progresión local luego de 9 meses.Primary squamous cell thyroid carcinoma (PSCTC is a rare and aggressive tumor of uncertain origin. When squamous carcinoma is diagnosed, it is mandatory to exclude the possibility of primary tumor arising from an adjacent structure or representing metastases from a primary growth elsewhere. Aggressive surgical resection is the treatment of choice. However, the prognosis is poor, with a median survival of less than a year. Death is usually secondary to progression of local disease. We report a case of a patient presenting with a thyroid mass; biopsy was consistent with squamous cell carcinoma. On immunohistochemistry tumor cells were negative for TTF1, thyroglobulin and calcitonin. Cancer cells were positive for p63 and citok5. Extensive workup excluded the possibility of extrathyroid origin. The patient was treated with chemoradiotherapy; he died 9 months later due to local progression.

    Mesenchymal stem cells (MSCs), which are capable of differentiating into multiple cell types, are reported to exert multiple effects on tumor development. However, the relationship between MSCs and nasopharyngeal carcinoma (NPC) cells remains unclear. Exosomes are small membrane vesicles that can be released by several cell types, including MSCs. Exosomes, which can carry membrane and cytoplasmic constituents, have been described as participants in a novel mechanism of cell-to-cell communicat...
