    Full Text Available Carcinomatous meningitis (CM occurs in 3 to 8% of cancer patients. Patients present with a focal symptom, and multifocal signs are often found following neurological examination. The gold standard for diagnosis remains the demonstration of carcinomatous cells in the cerebrospinal fluid on cytopathological examination. Despite the poor prognosis, palliative treatment could improve quality of life and, in some cases, overall survival. We report on a patient who presented with vertigo, tinnitus and left-sided hearing loss followed by progressive diffuse facial nerve paralysis. Lumbar cerebrospinal fluid confirmed the diagnosis of CM. However, no primary tumor was discovered, even after multiple invasive investigations. This is the first reported case in the English-language medical literature of CM resulting from a carcinoma of unknown primary origin.

    We retrospectively evaluated 41 patients with metastatic cervical tumors from unknown primary sites at the Hyogo College of Medicine between 1997 and 2007. The N stage classification of cervical lymph nodes was: N1 in 3 cases, N2a in 10 cases, N2b in 10 cases, N2c in 4 cases, and N3 in 14 cases. The histopathological diagnoses of cervical lymph node were: squamous cell carcinoma in 33 cases, adenocarcinoma in 5 cases, undifferentiated carcinoma in 2 cases, and papillary carcinoma in 1 cases. Primary tumor sites were: tonsil in 5 cases, esophaguses in 2 cases, hypopharynxies in 2 cases, and thyroid, oral floor, submandibular gland, lung, gastric and colon in 1 case each. The useful tests were gastric endoscope, positron emission tomography-computed tomography (PET-CT), and blind biopsy of tonsil. We treated 24 of the 41 patients. Therapies were: neck dissection with postoperative radiation therapy in 11 cases, neck dissection alone in 1 case, only radiation or chemoradiation therapy alone in 8 cases, and chemotherapy alone in 4 cases. The 5-year survival rate was 40.1% in all cases and 81.5% in cases who underwent neck dissection. (author)

    2015-04-01

    Merkel cell nodal carcinoma of unknown primary (MCCUP) is a rare neuroendocrine tumour with distinct clinical and biological behaviour. We conducted a review of retrospective data extracted from 90 patients focusing on the management and outcome of this disease. We also compared life expectancy of these patients with the outcome of patients with known Merkel primaries and with neuroendocrine cancers of unidentifiable primary. There is a limited body of data for this type of malignancy, however, patients with Merkel cell nodal carcinoma of unknown primary site, seem to have better survival when treated aggressively than patients with cutaneous Merkel tumours of the same stage and equal survival with patients with low-grade neuroendocrine tumour of unknown origin. The lack of prospective trials, and the inadequate data, hamper the management of these tumours. Establishment of treatment guidelines is urgently needed. Copyright © 2014 Elsevier Ireland Ltd.

    Full Text Available Kidney disease frequently complicates malignancy and its treatment. Although many solid and hematologic cancers may involve the renal parenchyma, clinical sequelae are usually not prominent. Published reports cite membranous nephropathy as the most common malignancy-associated glomerulopathy, occurring with many carcinomas and occasionally with leukemia and lymphoma followed by minimal change disease. Rarely membranoproliferative glomerulonephritis (MPGN has been reported in patients with malignancy. The mechanism by which malignancy induces disease remains unproved, but may involve deposition of tumor antigen in the subepithelial space with in situ immune complex formation and subsequent complement activation. Treatment of the underlying malignancy may lead to resolution of nephrotic syndrome, lending indirect support to this theory. We report a rare autopsy case of a patient with metastatic carcinoma (with unknown primary associated with MPGN. The association between MPGN and metastatic carcinoma with unknown primary is uncommon and has not been previously reported in the literature.

    Full Text Available Multiple sclerosis (MS is a chronic autoimmune disease that targets myelinated axons in the central nervous system (CNS. Cancer of unknown primary site (CUP is a well-recognised clinical disorder, accounting for 3–5% of all malignant epithelial tumors. CUP is clinically characterised as an aggressive disease with early dissemination. Studies of cancer risk in MS patients have shown inconsistent findings. An increased risk of malignancy in patients with MS has been suggested, but recently serious questions have been raised regarding this association. Use of disease-modifying therapies might contribute to an increased cancer risk in selected MS patients. The concurrence of MS and CUP is exceptionally rare. Here we describe the case of a neuroendocrine carcinoma of unknown primary diagnosed in a male patient with a nine-year history of MS. The discussion includes data from all available population-based register studies with estimates of certain malignancies in patients with MS.

    PURPOSE/OBJECTIVE: To evaluate the outcome of patients treated with radiotherapy for carcinoma metastatic to cervical lymph nodes from an unknown primary site. This large retrospective series updates the results of our treatment policy in which patients receive radiation both to the involved neck(s) at risk as well as putative mucosal primary sites along the pharyngeal axis. MATERIALS/METHODS: Between July 1968 and December 1992, 196 patients with carcinoma metastatic to cervical lymph nodes from an unknown primary site were treated with curative intent using megavoltage external beam radiotherapy. One hundred thirty-nine patients received adjuvant radiation following either an excisional biopsy or neck dissection (S+XRT), and 57 received radiation to gross disease following either a diagnostic biopsy or incomplete resection (XRT). A neck dissection was performed following radiation in patients in the XRT group who were medically and technically operable if there were residual masses following radiation. Nodal stage distribution was as follows: N1 - 32 patients, N2a - 65, N2b - 35, N2c - 15, N3 - 36, and NX - 13. Thirty percent of patients in the XRT group had N3 disease vs. 14% in the S+XRT group (p = .008). Similarly, 33% of patients in the XRT group presented with low jugular or supraclavicular adenopathy compared with 16% in the S+XRT group (p = .006). Radiation was delivered to putative mucosal sites in 173 patients. Of these, 172 were treated to the oropharynx, 167 to the nasopharynx, 124 to the larynx and hypopharynx, and 5 to the oral cavity. All but one patient received bilateral treatment when covering putative mucosal primary sites. Treatment was limited to the ipsilateral neck only in 23 patients. Doses ranged from 24 to 90 Gy. The median doses to the sites of nodal involvement were 63 Gy and 68.1 Gy for the S+XRT and XRT groups, respectively. RESULTS: The range of follow-up was 1-267 months with a median follow-up in surviving patients of 87 months

  11. An Unusual Presentation of Isolated Leptomeningeal Disease in Carcinoma of Unknown Primary With Pancreatic Features

    Full Text Available Leptomeningeal disease (LMD can occur in a small percentage of patients with active metastatic cancer. However, we report a case of LMD occurring during disease remission in a patient with carcinoma of unknown primary with panreaticobiliary features. A 45-year-old woman was found with mediastinal and abdominal lymphadenopathy with lymph node biopsy consistent with adenocarcinoma, expressing immunomarkers CK7, CK20, and Ca19-9 along with markedly elevated serum Ca19-9 level. The patient was started on a pancreatic cancer directed chemotherapy regimen of Folfirinox (5-fluorouracil, leucovorin, oxaliplatin, irinotecan and achieved complete response. She was then noted to have slowly rising Ca19-9 level that did not correlate with her lack of evidence of systemic disease progression. Eventually, she presented with neurologic symptoms and was found on imaging to have isolated LMD.

    The carcinoma of unknown primary occupied 5 - 10 % of all malignancies. It is heterogenous in origin and has poor prognosis. The indentification of primary site and definition of involved area are more helpful in the management. The efficacy of positron emission tomography (PET) with fluorine-18- fluorodeoxyglucose (F18-FDG) positron emission tomography (PET) with fluorine-18-fluorodeoxyglucose (F18-FDG) was evaluated in several tumors such as breast, pancreas and head and neck cancers. In carcinoma of unknown primary, it was reported that the concentration of FDG was increased in tumor tissues, and that PET with F18-FDG may be much helpful in identifying primary site and defining involved area. The authors evaluated the usefulness of PET with F18-FDG in initial work-up and in evaluation after radical therapy for the patients with carcinoma of unknown primary. The visual analysis of FDG-PET would be helpful in identifying primary site and defining involved area. In detecting recurrent of residual lesions, FDG-PET seemed to be less helpful than conventional diagnostic work-up. But more studies with larger number of cases and longer follow-up were required. The results of this study can be bases for the direction of future studies for the usefulness of PET in carcinoma of unknown primary.

    Full Text Available Background/Aim. Unknown primary tumors represent a heterogeneous group of malignancies that are indicative of ominous prognosis. Cancer of unknown primary site (CUP is defined as the lack of any detectable primary site after full evaluation, and accounts for approximately 3-5% of all newly diagnosed patients with malignancies. The aim of this report was to present the prognostic and predictive value of 8 serum tumor markers in this group of patients. Methods. The study involved 63 patients. On histological examination, all the patients were presented with metastatic tumors whose primary site (origin could not be detected with noninvasive diagnostic techniques. Following the routine light microscopy, all histological findings were classified into one of the following three groups: plano-cellular carcinoma - 8 patients; adenocarcinoma - 33 patients; unclassifiable (undifferentiated carcinoma - 22 patients. In all the cases we evaluated 8 serum tumor markers: alpha-fetoproteins (AFP, chronic gonadotrophin beta submit, human (beta-HCG, neuron specific enolase (NSE, marker of malignant ovarian tumors (CA 125, prostate-specific antigene (PSA, marker of malignant brest tumor (CA 15-3, marker of malignant pancreas tumor and gastrointestinal tumor (Ca 19-9, carcinoembryonic antigen (CEA at the time of diagnosis. The patients on chemotherapy had the markers determined after the third and sixth chemocycle, i.e. at the time of illness progression observation, if present. The patients responding to chemotherapy with complete response (CR, partial response (PR or stable disease (SD had the markers determined after three-month periods until the time of relapse or progression. Chemotherapy was applied in 32 patients (20 females and 12 males, aged 29-70 years, who met the inclusion criteria. The following chemotherapy regimen was used: doxorubicin 50mg/m2 (day 1, cisplatin 60mg/m2 (day 1, and etoposide 120 mg/m2 (days 1-3. The period between two chemotherapy

    Full Text Available Abstract Background Carcinomas of unknown primary site (CUP are epithelial malignancies revealed by metastatic lesions in the absence of any detectable primary tumor. Although they often adopt an aggressive clinical pattern, their basic biology remains poorly understood. Laboratory research on their biology have been hampered so far by the absence of cell lines representative of CUPs. Methods We attempted xenografts of CUP clinical specimens in immunodeficient mice and subsequent in vitro culture of transplanted malignant cells. Whenever possible, malignant xenografted or cultured cells were characterized by microsatellite genotyping, immunohistology, electron microscopy, multifish chromosome analysis and search of TP 53 gene mutations. Results Successful xenografts were achieved in 2 cases out of 4. One of them (Capi1 was lost after 3 passages whereas the other one (Capi3 has been adapted to in vitro culture and is currently available to the scientific community with reliable identification based on microsatellite genotyping. Both Capi1 and Capi3 have histological characteristics of adenocarcinomas and display intense expression of EMA, CEA and cytokeratin 7. Multifish chromosome analysis demonstrated a translocation involving chromosomes 4 and 21 in both specimens. Distinct rare missense mutations of the TP53 gene were detected in Capi1 (codon 312 and Capi3 (codon 181; the codon 181 mutation is consistent with a previously reported similar finding in a small series of CUP specimens. Finally, intense membrane expression of c-kit was recorded in Capi3. Conclusion Our data suggest that xenografted tumors can be obtained from a substantial fraction of CUP clinical specimens. The hypothesis of a preferential association of CUPs with TP 53 mutations of codon 181 deserves further investigations. The Capi3 cell line will be a useful tool for assessment of novel c-kit inhibitors.

    Shah, Ameer T; Dagher, Walid I; O'Leary, Miriam A; Wein, Richard O

    The differential diagnosis of facial anesthesia is vast. This may be secondary to trauma, neoplasm, both intracranial and extracranial, infection, and neurologic disease. When evaluating a patient with isolated facial anesthesia, the head and neck surgeon often thinks of adenoid cystic carcinoma, which has a propensity for perineural invasion and spread. When one thinks of head and neck squamous cell carcinoma with or without unknown primary, the typical presentation involves dysphagia, odynophagia, weight loss, hoarseness, or more commonly, a neck mass. Squamous cell carcinoma presenting as facial anesthesia and perineural spread, with no primary site is quite rare. Case presentations and review of the literature. Trigeminal anesthesia is an uncommon presentation of head and neck squamous cell carcinoma with unknown primary. We present two interesting cases of invasive squamous cell carcinoma of the trigeminal nerve, with no primary site identified. We will also review the literature of head and neck malignancies with perineural spread and the management techniques for the two different cases presented. Copyright © 2016 Elsevier Inc.

    Objectives: Carcinoma of unknown primary (CUP) in the abdomen and pelvis is a heterogeneous group of cancers with no standard treatment. Considered by many to be incurable, these patients are often treated with chemotherapy alone. In this study, we determined the effectiveness of radiation therapy in combination with chemotherapy in patients with CUP in the abdomen and pelvis. Patients and Methods: Medical records were reviewed for 37 patients with CUP treated with radiation therapy for disease located in the soft tissues and/or nodal basins of the abdomen and pelvis at University of Texas M.D. Anderson Cancer between 2002 and 2009. All patients underwent chemotherapy, either before or concurrent with radiation therapy. Patients were selected for radiation therapy on the basis of histologic type, disease extent, and prior therapy response. Twenty patients underwent definitive radiation therapy (defined as radiation therapy targeting all known disease sites with at least 45 Gy) and 17 patients underwent palliative radiation therapy. Only 6 patients had surgical resection of their disease. Patient and treatment characteristics were extracted and the endpoints of local disease control, progression-free survival (PFS), overall survival (OS), and treatment-related toxicity incidence were analyzed. Results: The 2-year PFS and OS rates for the entire cohort were 32% and 57%, respectively. However, in patients treated with definitive radiation therapy, the rates were 48% and 76%, and 7 patients lived more than 3 years after treatment with no evidence of disease progression. Nevertheless, radiation-associated toxicity was significant in this cohort, as 40% experienced Grade 2 or higher late toxicities. Conclusions: The use of definitive radiation therapy should be considered in selected patients with CUP in the soft tissues or nodal basins of the abdomen and pelvis.

    Merkel cell carcinoma is a rare and aggressive neuroendocrine tumor that commonly arises in the skin. It is rare for it to occur in the testes. There are only seven cases of testicular Merkel cell carcinoma reported in the literature. A 66-year-old Maori man presented to our hospital with left testicular swelling. His alpha-fetoprotein and beta-human chorionic gonadotrophin levels were within normal limits. His lactate dehydrogenase concentration was elevated to 267 U/L. Ultrasound imaging confirmed a large testicular mass, and he underwent left orchiectomy. His histological examination revealed a neuroendocrine tumor with an immunostaining pattern suggesting Merkel cell carcinoma. He presented to our hospital again 3 months later with right testicular swelling that was confirmed on ultrasound sonography to be a tumor. He underwent a right orchiectomy, and his histological examination revealed metastatic Merkel cell carcinoma. A primary lesion was not identified, and computed tomographic imaging did not reveal spread to other organs. He received six cycles of adjuvant carboplatin and etoposide chemotherapy and remained disease-free 18 months after completion of chemotherapy. Given the paucity of studies, standard adjuvant treatment for testicular Merkel cell carcinoma remains uncertain, although platinum-based chemotherapy seems to be an appropriate option.

    Full Text Available Objective: To analyse the clinicopathologic characteristics of visceral metastatic carcinoma of unknown primary site (VMCUP, discuss the relationship between its treatment and prognosis, and provide the basis for individualized clinical diagnosis and treatment. Methods: A retrospective analysis on clinical pathologic data was performed on 21 VMCUP cases from Fujian Union Hospital from January 2007 to January 2012. Follow-up visits on patients were made and analysis of their survival conditions and relevant influencing factors were collated. Results: The gender distribution of the 21 VMCUP cases was 1:1.1; the median age was 63 years and the pathology type was dominated by adenocarcinoma. The median survival time and survival rate in patients accepting treatment were evidently higher than those in patients not accepting treatment. The median survival time of those patients receiving more than one treatment procedure was higher than in those patients only receiving chemotherapy. Among those patients who received comprehensive therapy, the median survival time in those mainly receiving operative therapy was also higher than in those only receiving chemotherapy (p two cycles or > four cycles was evidently longer than those receiving chemotherapy ≤ two cycles or ≤ four cycles separately. For those choosing paclitaxel in combination with platinum as first-line chemotherapy, their median survival time was longer than those primarily taking fluorouracil (p 0.05 in the median survival times among groups receiving the same treatment but with different age, gender or pathological types. It was indicated by multiple-factor analysis that the chemotherapeutics, chemotherapy times and treatment methods were prognostic factors affecting the survival of VMCUP. Conclusion: The overall progression of VMCUP patients deteriorates quickly, with a poor prognosis and without a standard treatment pattern. Appropriate chemotherapy, surgery and radiotherapy, however

    Patients with Cancer of unknown primary (cup) represent 2-10%, and have disseminated cancers for which we cannot find the primary site despite the clinical, pathological and radiological exams at our disposal. Diagnosis is based on a thorough clinical and histopathologic examination as well as new imaging techniques. Several clinicopathologic entities requiring specific treatment can be identified. Genome sequencing and liquid biopsy (circulating tumor cells and tumor free DNA) could allow further advances in the diagnosis. Therapeutically, in addition to surgery, radiotherapy and chemotherapy, precision medicine provides new therapeutic approaches. Copyright © 2016 Société Française du Cancer.

    2018-02-01

    Full Text Available Lenvatinib is an oral tyrosine kinase inhibitor of vascular endothelial growth factor receptors 1, 2, and 3, fibroblast growth factor receptors 1 through 4, as well as platelet-derived growth factor receptor α, RET, and KIT. At present, lenvatinib is used in the treatment of thyroid cancer and renal cell carcinoma. We herein report a case of a 67-year-old patient with squamous cell carcinoma of unknown primary who was effectively treated with lenvatinib. The patient was initially diagnosed as having undifferentiated thyroid cancer, and after total thyroidectomy and bilateral lymph node dissection, lenvatinib was administered for the treatment of residual lymph node metastasis. A computed tomography scan after 1 month of lenvatinib administration showed marked regression of the lymph nodes, but interstitial pneumonia was also detected. Because the drug lymphocyte stimulation test for lenvatinib was strongly positive, we concluded that the interstitial pneumonia was induced by lenvatinib. The interstitial pneumonia only improved by the withdrawal of lenvatinib. Finally, his thyroid tumor was diagnosed as a metastasis of squamous cell carcinoma; however, we were unable to identify the primary lesion. This is the first reported case of interstitial pneumonia induced by lenvatinib.

    Background Carcinoma of unknown primary (CUP) encompasses a heterogeneous group of tumors with varying clinical features. The management of patients of CUP remains a clinical challenge. The purpose of this study was to evaluate the clinical applications of integrated 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) information in patients with CUP,including detecting the occult primary tumor and effecting on disease therapy.Methods One hundred and forty-nine patients with histologically-proven metastases of CUP were included. For all patients,the conventional diagnostic work-up was unsuccessful in localizing the primary site. Whole-body PET/CT images were obtained approximately 60 minutes after intravenous injection of 350-425 MBq of 18F-FDG.Results In 24.8% of patients,FDG PET/CT detected primary tumors that were not apparent after conventional workup.In this group of patients,the overall sensitivity,specificity,and accuracy rates of FDG PET/CT in detecting unknown primary tumors were 86.0%,87.7%,and 87.2%,respectively. FDG PET/CT imaging also led to the detection of previously unrecognized metastases in 29.5% of patients. Forty-seven (31.5%,47 of 149) patients underwent a change in therapeutic management.Conclusions FDG PET/CT is a valuable tool in patients with CUP,because it assisted in detecting unknown primary tumors and previously unrecognized distant metastases,and optimized the mangement of these patients.

    Full Text Available Metastatic carcinoma of unknown primary (CUP has a very poor prognosis, and no standard first-line therapy currently exists. Here, we report the results of a phase II study utilizing a combination of gemcitabine and irinotecan as first-line therapy. Treatment was with gemcitabine 1000 mg/m(2 and irinotecan 75 mg/m(2 weekly times four on a six week cycle (Cohort I. Due to excessive toxicity, the dose and schedule were modified as follows: gemcitabine 750 mg/m(2 and irinotecan 75 mg/m(2 given weekly times three on a four week cycle (Cohort II. The primary endpoint was the confirmed response rate (CR + PR. Secondary endpoints consisted of adverse events based upon the presence or absence of the UDP glucuronosyltransferase 1 family, polypeptide A1*28 (UGT1A1*28 polymorphism, time to progression, and overall survival. Thirty-one patients were enrolled with a median age of 63 (range: 38-94, and 26 patients were evaluable for efficacy. Significant toxicity was observed in Cohort 1, characterized by 50% (7/14 patients experiencing a grade 4+ adverse event, but not in cohort II. The confirmed response rate including patients from both cohorts was 12% (95% CI: 2-30%, which did not meet the criteria for continued enrollment. Overall median survival was 7.2 months (95% CI: 4.0 to 11.6 for the entire cohort but notably longer in cohort II than in cohort I (9.3 months (95% CI: 4.1 to 12.1 versus 4.0 months (95% CI: 2.2 to 15.6. Gemcitabine and irinotecan is not an active combination when used as first line therapy in patients with metastatic carcinoma of unknown primary. Efforts into developing novel diagnostic and therapeutic approaches remain important for improving the outlook for this heterogeneous group of patients.ClinicalTrials.gov NCT00066781.

We report the case of nodal metastasis of unidentified primary squamous cell carcinoma in a 58 years old patient with white skin and a history of good health. The patient was a housekeeper who smoked from early age and frequently consumed alcohol. She was admitted with an enlargement of the neck glands. Metastases of squamous cell carcinoma were diagnosed through biopsy. Primary cancer was not identified neither while still alive or at necropsy. Primary metastatic cancers of unknown origin remain a challenge for clinical practice.

    Carcinoma of unknown primary is one of the ten most frequent cancers worldwide. Its median survival time is less than 10 months. Detecting primary tumour locations and/or occult metastatic lesions may inform definitive treatment and improve patients' prognosis. We aimed to determine: (1) the sensitivity, specificity and accuracy of (18)F-fluoro-2-deoxyglucose positron emission tomography/computed tomography; (2) its detection rate of primary tumour locations and occult metastases and (3) factors associated with improved survival times. We retrospectively reviewed all cases in the West of Scotland for the period 1 December 2007 to 31 May 2011 that met all our selection criteria: (1) diagnosis of carcinoma of unknown primary; (2) a thorough but negative 'work-up' and (3) (18)F-fluoro-2-deoxyglucose positron emission tomography/computed tomography report. Statistical methods included frequencies, Kaplan-Meier graphs and log-rank tests to compare survival times. (18)F-fluoro-2-deoxyglucose positron emission tomography/computed tomography detected primary tumour sites in 19/51 (37.3%) and occult metastases in 28/51 (54.9%) of eligible patients. Its sensitivity, specificity and accuracy were 79.2%, 70.4% and 74.5%, respectively; 20/51 (39.2%) patients died during the study period with a median survival of 8.4 months (range 21.4, SD ± 6.2). The number of metastatic locations was strongly associated with survival (p = 0.002), but detection of a primary tumour site (p = 0.174) or histopathology (p = 0.301) was not. (18)F-fluoro-2-deoxyglucose positron emission tomography/computed tomography detected occult metastatic sites in the majority and a primary cancer location in a substantial minority of patients. Our results were comparable with international literature and may indicate that (18)F-fluoro-2-deoxyglucose positron emission tomography/computed tomography have an early role to improve the accuracy of cancer staging and to optimise carcinoma of unknown

    Full Text Available BACKGROUND Carcinoma of unknown primary with secondary metastasis to neck (CUPS Neck is involvement of cervical nodes with squamous cell carcinoma without identifiable primary lesion in oral cavity, oropharynx and upper aerodigestive tract. Most commonly affects older male with history of tobacco and alcohol abuse. Commonly involved neck nodes are level II and III. Metastasis to these nodes usually comes from head and neck tumours. The aims of this study are to evaluate the factors (relating to patient and disease associated with improved outcomes following treatment in patients with metastatic squamous cell carcinoma of neck with unknown primary site. MATERIALS AND METHODS Study was done in ENT and Head Neck Centre, Base Hospital, Delhi Cantt. The investigation and treatment of such cases aim to detect a primary lesion, if possible in the upper aerodigestive tract (UADT and in any case to institute the optimal management protocol. Many factors impact the outcomes of treatment in terms of survival and quality of life. RESULTS After followup of 0.5 to 2 years data were compared among various groups, various disease related factors like volume of disease, staging of neck node, extracapsular spread in final HPE report and various patient related factors like age and sex of patient, performance status of patient, and presence of comorbidities were compared with final outcome in terms of recurrence or disease free survival with less complications. CONCLUSION 1. Most prominent tumour related prognostic factors were low volume nodal disease in the neck and absence of extracapsular spread. Patients with TNM stage I (T0N1M0 were associated with lower recurrence and less complication postoperatively as compared to advanced stage disease (T0N2M0 and T0N3M0. 2. In our study, patient related variables associated with superior patient outcomes in terms of locoregional recurrence or disease free survival were good performance status, females, young age

    To determine the rate of subsequent primary site failure in patients with head and neck squamous cell carcinoma of unknown primary (UKP HNSCC) in a region with a high prevalence of cutaneous squamous cell carcinoma, according to a pre-determined institutional policy. Secondary aims included regional and distant control, and overall survival. Patients presenting between April 2005 and June 2016 to the Princess Alexandra Hospital Head and Neck Multidisciplinary Meeting with UKP HNSCC from either presumed mucosal or cutaneous sites treated with curative intent were eligible. Patients with presumed mucosal origin were treated with radiation therapy (RT) with or without chemotherapy, while patients with presumed cutaneous SCC were treated with surgery and post-operative RT with or without chemotherapy. A total of 63 patients met the inclusion criteria. Median follow up duration was 3.9 years (IQR 2.07-5.14). There were no subsequent primary site failures. The rate of nodal failure among presumed mucosal patients was 11.5%, and 8.1% among presumed cutaneous patients. The rate of distant metastatic failure was 11.1% among all patients. The estimated 5 year overall survival was 71.2% (95% CI 59.2-85.7%). Treatment according to our pre-defined institutional policy for UKP HNSCC in a region with a high prevalence of cutaneous SCC appears to be safe and effective with low rates of mucosal primary emergence and nodal failure.

    Objective: Carcinoma of unknown primary (CUP) is not uncommon in usual clinical settings. They are, by definition, those cases with clinically suspected primary malignancy but not revealed by conventional investigation. The aim of this study was to investigate the efficacy of whole-body 18 F-fluoro- deoxyglucose (FDG) PET/CT in detecting a primary neoplasm for these patients. Methods: A totle of 150 patients with retrievable records from 169 CUP patients were selected within a group of consecutive 2589 patients from Jan. 2006 to Jun. 2007. All cases underwent whole-body FDG PET/CT scan. The final diagnoses were confirmed by pathologic results, other imaging modalities or clinical follow-up. Results: Among 150 patients, primary tumor sites were successfully detected by whole-body 18 F-FDG PET/CT scan in 70 cases (46.7%), of which 52 were pathologically confirmed and 18 by clinical follow-up. And 38 cases (54.3%) were lung cancer, 8 (11.4%) were nasopharyngeal carcinoma, 13 (18.6%) in digestive sys- tem, and 11 (15.7%) in other systems. Three clinically suspected CUP cases with negative 18 F-FDG PET/ CT were subsequently confirmed of benign processes by clinical follow-up. Six patients were wrongly diagnosed by 18 F-FDG PET/CT, and 15 patients did not have a confirmed diagnosis by the end of research. The primary cause of malignancy after 18 F-FDG PET/CT remained obscure in 56 patients, only 3 of whom be- came known during the course of clinical follow-up (nasopharyngeal bladder and esophageal carcinoma). Conclusion: 18 F-FDG PET/CT whole-body imaging plays an important role in patients with metastatic CUP. (authors)

    Aim: Treatment of patients with carcinoma of unknown primary localized to the neck only is still controversial. To determine both patient related prognostic factors and the influence of treatment parameters the records of 99 patients were analyzed retrospectively, to evaluate the role of F-18-FDG PET for diagnostics and therapy management 33 patients were analyzed prospectively. Material and Methods: Retrospectively: Out of 99 patients with carcinoma of unknown primary, 51 received surgery as a sole treatment. 48 were treated with a combination of surgery and radiation therapy. 8/99 patients received a F-18-FDG PET. Statistical analyses: Kaplan-Meier, log-rank-test, chi-square-test. Prospectively: All PET studies were carried out after conventional diagnostic procedures failed to detect the primary tumor. PET findings were correlated with histology and/or clinical course of the patients. Results: Retrospectively: Disease specific survival (DSS) was significant longer for patients with N1/N2 vs. N3 (p=0.03), for upper nodal involvement vs. lower and/or supraclavicular nodal involvement (p=0.031) and for absence of extracapsular spread (p=0.041). No influence of DSS was noted for grading (p=0.469), treatment volume (p=0.82) and applied dose (>50Gy vs. <50Gy). In 2/8 patients, PET detected the primary tumor, in 1/8 bone metastases. Prospectively: Detection of the primary tumor by PET was successful in 21%, mostly in patients with lower and/or supraclavicular nodal involvement. In these patients the primary tumor was located extracervically in 72%, e.g. lung or gastric cancer. Distant metastases were detected in 33%. Conclusion: The presence of ECS, the extend and localization of nodal involvement are prognostic factors in patients suffering from CUP localized to the neck only. Patients with upper nodal involvement should be treated with curative intention. The irradiation fields should cover the whole neck including the potential region of the primary tumor with doses

    Purpose: To compare the outcome for patients with squamous cell carcinoma of cervical lymph nodes metastatic from an unknown primary site who were irradiated to both sides of the neck and potential mucosal sites with opposed photon beams, and for those irradiated to the ipsilateral side of the neck alone with an electron beam. Methods and Materials: Fifty-two patients with squamous cell carcinoma metastatic to cervical lymph nodes from an unknown primary site were irradiated by two different methods. Thirty-six were irradiated with a bilateral technique (BT), i.e., to both sides of the neck, including the naso-oro-hypopharyngeal mucosa, and 16 were irradiated with an electron beam (EB) to the ipsilateral side of the neck alone. Twenty patients of the BT group and 11 of the EB group had cervical lymph node dissections, and the remaining 21 patients had lymph node biopsies, prior to radiotherapy. Results: Tumor control in the ipsilateral side of the neck did not differ for either radiation technique, but was significantly higher after lymph node dissection than after biopsy (90 vs. 48%; p = 0.0004). Control of subclinical metastases in the contralateral cervical lymph nodes was higher for patients irradiated with BT than for patients irradiated with EB (86 vs. 56%; p 0.03). The occult primary was later discovered in 8% of the patients in the BT group and 44% of the EB group (p = 0.0005). The disease-free survival rate at 5 years for patients who had lymph node dissection prior to irradiation was 61%, and was 37% for those who had biopsy (p = 0.05). Only 20% of patients who subsequently developed an occult primary were salvaged and survived for 5 years after salvage treatment. Conclusion: Bilateral neck and mucosal irradiation is superior to ipsilateral neck irradiation in preventing contralateral cervical lymph node metastases and the subsequent appearance of an occult primary cancer. Both techniques combined with cervical lymph node dissection were equally effective

    The goal was to retrospectively review the outcome of patients with cervical lymph node metastases of squamuos cell carcinoma of unknown primary site (CUP) treated with radio(chemo)therapy. Patients and methods A total of 65 patients with CUP N1-3, M0, treated between 1988 and 2009 were evaluated: 61 patients underwent surgical resection followed by postoperative radio(chemo)therapy, 4 patients received definitive radiochemotherapy. Radiotherapy of bilateral neck nodes + the parapharyngeal region (COMP-RT) was performed in 48 patients (80%) and a unilateral radiotherapy of lymph nodes (UL-RT) in 17 patients (20%). Results After a median follow-up time of 64 months (range 3-219 months), the estimated 2- and 5-year overall survival (OS) rates were 71 ± 6% and 48 ± 7%, respectively. The recurrent free survival (RFS) rate at 2- and 5-years was 58 ± 6% and 48% ± 7%, respectively. Extracapsular spread, resection status (R0 vs. R1/R2), neck lymph node level (I-III vs. IV-V), and Karnofsky index (60-70 vs. 80-100) were significant prognostic factors for OS and RFS in the univariate analysis. Lower nodal stage (N1/N2a vs. N2b/N2c/N3) was significantly associated with a better OS. Resection status and involvement of lymph node level IV significantly affected the OS and RFS in the multivariate analysis. COMP-RT or concurrent chemotherapy was not associated with a better OS or RFS. Conclusion An advantage of comprehensive radiotherapy or radiochemotherapy compared with unilateral radiotherapy of lymph nodes was not observed. (orig.)

    Full Text Available Little is known about the clinical importance of intramammary lymph node metastasis of breast cancer, even though it is not rare. In the present paper, the authors present an unusual, rare case of an intramammary lymph node metastasis of an unknown primary, probably occult breast cancer, and its management. The patient was submitted to various staging exams and surgical procedures and a definitive diagnosis was not established. From a multidisciplinary context, it was assumed that the patient had a breast triple negative primary with axillary involvement. This decision lead to adjuvant chemo and radiotherapy. Challenging cases like the one described here, should always be managed within the multidisciplinary team context and recorded in the institution’s database.

    Full Text Available Carcinoma of unknown primary origin (CUP accounts for 2-10% of all malignancies. The apparent absence of the primary tumour, the development of early, uncommon systemic metastases and the resistance to therapy and poor prognosis are hallmarks of this heterogeneous clinical entity and are a challenge for physicians. The diagnostic workup of patients with CUP includes a large amount of histopathological examination, as well as the use of imaging techniques that often fail to identify the primary tumour. Therefore, the optimal workup and treatment for these patients remains to be determined. Molecular diagnostic tools, such as DNA microarray analysis, could help in the search for "lost" CUP origin and guide the further treatment approach. We report the case of a 66-year-old man, with mediastinal lymph nodes metastasis of carcinoma and neurological syndrome with diplopia and balance disorders, in which many exams have been performed without finding the primary tumour.

    Merkel cell carcinoma (MCC) is an aggressive skin tumor with a high tendency for metastases. We report a case of MCC initially presenting as axillary and pancreatic metastases. A 33-year-old HIV-positive Hispanic male presented with a history of a rapidly growing axillary mass. A needle core biopsy demonstrated an epithelioid neoplasm composed of small to medium-sized cells with high nuclear-cytoplasmic ratio, nuclear molding, and frequent mitotic figures. A subsequent PET scan revealed a 1.5 cm FDG avid mass in the pancreas. Endoscopic ultrasound-guided FNA of the pancreatic mass showed neoplastic cells with similar morphology to those of the axillary mass. The tumor cells were positive with pancytokeratin AE1/AE3, CK20, CD56, synatophysin, chromogranin, and Merkel cell polyomavirus (MCPyV). This case of MCC most likely originated from a resolved primary skin lesion drained by the involved axillary lymph node with subsequent metastases to the pancreas and distant lymph nodes. © 2017 Wiley Periodicals, Inc.

    Highlights: • Both 18F-FDG PET/CT and 18F-FDG PET/MRI provide a comparable diagnostic ability for detection of primary cancer and metastases in CUP-syndrome. • Both imaging methods showed comparably high lesion conspicuity and diagnostic confidence (superior assessment of cervical lesions in PET/MRI). • PET/MRI may serve as a powerful alternative, particularly for therapy monitoring or surveillance considering the long-term cumulative dose. - Abstract: Purpose: The aim of this study is to evaluate and compare the diagnostic potential of integrated whole-body [18F]FDG-PET/MRI to [18F]FDG-PET/CT for detection of a potential primary cancer and metastases in patients suspected for cancer of unknown primary (CUP). Methods: A total of 20 patients (15 male, 5 female, age 53 ± 13 years) suspect for CUP underwent a dedicated head and neck & whole-body [18F]FDG-PET/CT (Biograph mCT 128, Siemens Healthcare) and a subsequent simultaneous [18F]FDG-PET/MRI examination (Biograph mMR, Siemens Healthcare). Two readers rated the datasets (PET/CT; PET/MRI) regarding the detection of the primary cancer and metastases, lesion conspicuity (4-point ordinal scale) and diagnostic confidence (3-point ordinal scale). PET analysis comprised the assessment of maximum standardized uptake values (SUVmax) of all PET-positive lesions using volume of interest (VOI) analysis derived from the PET/CT and PET/MR datasets. All available data considering histology and imaging including prior and clinical follow-up examinations served as reference standard. Statistical analysis included comparison of mean values using Mann-Whitney U test and correlation of SUVmax using Pearson‘s correlation. Results: In 14 out of 20 patients 49 malignant lesions were present. The primary cancer could be correctly identified in 11/20 patients with both PET/CT and PET/MRI. PET/CT enabled the detection of a total 38 metastases, PET/MR respectively of 37 metastases (one lung metastasis <5mm was missed). PET/CT and

    The records of 54 consecutive patients who were irradiated for metastatic disease in the neck from an unknown primary tumor were reviewed. The overall survival results are comparable to those of other reported series. Patients with high or posterior cervical lymph node involvement were irradiated with fields including the nasopharynx and oropharynx. Patients with high neck nodes had a better survival rate than those with low neck nodes. The size of the neck tumors and the local control after treatment also have prognostic significance. (Auth.)

    Full Text Available Primary Fallopian Tube Carcinoma (PFTC is rare and accounts for about 0.3% of all gynecologic cancers. Less than 1500 cases have been reported in the literature. It arises in postmenopausal women and typically presents with abdominal pelvic pain, vaginal bleeding and watery discharge. However, a correct diagnosis is rarely achieved preoperative, and in many cases, the diagnosis is made after incidental surgery for unrelated conditions commonly being ovarian carcinoma . Compared with ovarian carcinoma, PFTC more often presents at early stages, but it has a worse prognosis. PFTC is usually managed in the same manner as ovarian cancer. We report a case of Left PFTC that presented as Left ovarian mass, and we briefly review the literature.

    The aim of this retrospective study was to describe clinical features, treatment and outcome of 21 dogs with metastatic cancer of unknown primary (MCUP), a biopsy-proven malignancy being diagnosed at a metastatic stage, in which the anatomical origin of the primary tumour cannot be detected. All dogs underwent total-body computed tomography. Signalment, type and duration of clinical signs, metastasis site, pathology results, treatment and outcome were recorded. Carcinoma was the most common diagnosis (57.1%), followed by sarcoma, melanoma and mast cell tumour. The median number of disease sites per dog was 2, with bones, lymph nodes, lungs and spleen being the most frequent metastatic locations. The median survival for all dogs was 30 days. Overall, a primary site was not identified in 20 (95.2%) dogs. MCUP encompasses a variety of different pathologic entities and harbours a poor prognosis. © 2013 Blackwell Publishing Ltd.

    Primary carcinoma of the duodenum represents about 0.35% of all gastrointestinal carcinomas and is thus a rare disease. The radiological diagnosis of a duodenal origin is made more difficult by the close proximity of the pancreas, biliary system, right kidney and transverse colon. Histologically, duodenal malignant tumours are usually adenocarcinomas. Between 1973 and 1983, eight patients with primary duodenal carcinomas were diagnosed at the University of Tuebingen. Average age of the patients was 67 years. There was no sex difference. Average survival was 3.3 years. (orig.) [de

    A case of metastatic carcinoma of unknown primary is reported that had widely disseminated disease from the very outset. Every effort was made to find out the primary by integrating all results and specially tumor markers. It was assumed that lung was the most possible site for primary. Tumor markers did not show their diagnostic value even in combined panel, they only showed their prognostic value. (author)

    Full Text Available Adrenal sarcomatoid carcinomas are extremely rare tumors presenting with extensive locoregional spread at the time of diagnosis. Patients succumb to metastases within a couple of months. As a result, very few cases are reported in the literature until now. We present a case of a 62-year old female with non-functional sarcomatoid carcinoma of the right adrenal gland. There was no radiological evidence of locoregional metastases. Patient underwent right adrenalectomy. Follow up after 3 months showed para-aortic lymphadenopathy and similar left adrenal mass on computed tomography. Patient refused further treatment and succumbed to the disease. A brief case report with review of literature is presented.

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

    Cancer of unknown primary origin (CUP) is one of the ten most frequent cancers worldwide. It constitutes of 3-5% of all human malignancies. At time of diagnosis patients with CUP present with disseminated metastases without established primary origin. CUP manifests as heterogenous group of mainly epithelial cancers recognised by distinct clinico pathological entities. The diagnostic work-up includes extensive histopathology investigations and modern imaging technology. Nevertheless, the primary tumour remains undetected most of the time. (author)

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

    Science.gov (United States)

    2015-01-01

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

    Full Text Available We describe a case of anaplastic meningioma presenting in an extracranial osseous location, initially diagnosed as cancer of unknown primary. Although anaplastic meningioma comprise 3% of all meningiomas, this subtype is more likely to be associated with metastases. The increased degree of dedifferentiation in anaplastic meningioma makes diagnosis difficult, especially if characteristic imaging findings of meningioma are not identified. Adequate tissue for diagnostic purposes and appropriate imaging studies may help in establishing a definitive diagnosis.

    Cancer of unknown primary remains a mallignancy of elusive biology and grim prognosis that lacks effective therapeutic options. We investigated angiogenesis in cancer of unknown primary to expand our knowledge on the biology of these tumors and identify potential therapeutic targets. Paraffin embedded archival material from 81 patients diagnosed with CUP was used. Tumor histology was adenocarcinoma (77%), undifferentiated carcinoma (18%) and squamous cell carcinoma (5%). The tissue expression of CD34, VEGF and TSP-1 was assessed immunohistochemically by use of specific monoclonal antibodies and was analyzed against clinicopathological data. VEGF expression was detected in all cases and was strong in 83%. Stromal expression of TSP-1 was seen in 80% of cases and was strong in 20%. The expression of both proteins was not associated with any clinical or pathological parameters. Tumor MVD was higher in tumors classified as unfavorable compared to more favorable and was positively associated with VEGF and negatively with TSP-1. Angiogenesis is very active and expression of VEGF is almost universal in cancers of unknown primary. These findings support the clinical investigation of VEGF targeted therapy in this clinical setting

    Head and neck squamous cell carcinoma with occult primary site represents a controversial clinical problem. Conventional total mucosal irradiation (TMI) maximizes local control, but at the expense of xerostomia. IMRT has been shown to spare salivary tissue in head and cancer patients. This study has been performed to investigate the potential of IMRT to perform nodal and TMI and also allow parotid gland sparing in this patient group. Conventional radiotherapy (CRT) and IMRT plans were produced for six patients to treat the ipsilateral (involved) post-operative neck (PTV1) and the un-operated contralateral neck and mucosal axis (PTV2). Plans were produced with and without the inclusion of nasopharynx in the PTV2. The potential to improve target coverage and spare the parotid glands was investigated for the IMRT plans. There was no significant difference in the mean doses to the PTV1 using CRT and IMRT (59.7 and 60.0 respectively, p = 0.5). The maximum doses to PTV1 and PTV2 were lower for the IMRT technique as compared to CRT (P = 0.008 and P < 0.0001), respectively, and the minimum doses to PTV1 and PTV2 were significantly higher for IMRT as compared to CRT (P = 0.001 and P = 0.001), respectively, illustrating better dose homogeneity with IMRT. The mean dose to the parotid gland contralateral to PTV1 was significantly lower for IMRT (23.21 ± 0.7) as compared to CRT (50.5 ± 5.8) (P < 0.0001). There was a significant difference in parotid dose between plans with and without the inclusion of the nasopharynx. IMRT offers improved dose homogeneity in PTV1 and PTV2 and allows for parotid sparing

    2013-01-01

    Cancer of unknown primary origin (CUP) comprises a heterogenous group of cancers with distinct biology and prognosis. There is, however, a specific group of patients with curable diseases, or incurable diseases with good prognosis. The main aim of treatment in the group of patients with CUP is timely initiation of therapy in the cases of curable disease. There is no known standard of care in the cases of CUP with poor prognosis, but most frequently, platinum-based regimens are used. In the cases of specific immunohistochemistry (IHC) or molecular gene expression profile, there are used the treatment regimens similar to those used in the patients with known primary tumor and similar IHC or molecular profile. Currently, most of data in patients with CUP are from phase II clinical trials. Thus proficiently designed phase III randomized clinical trials with translation research is priority, with aim to improve our knowledge and personalize treatment of such heterogenous group of patients as is a group of patients with CUP.

    2-4% of newly diagnosed cases of malignant disease involve cancer of unknown primary (CUP). This mixed entity is one of the 6 most common types of malignant disease in Germany. Highly refined treatment strategies can now be offered to patients with CUP. This review is based on pertinent publications retrieved by a selective search in PubMed with an emphasis on articles from the past decade. The current guidelines and recommendations of specialty societies were also considered in the evaluation. CUP most commonly manifests itself as metastases to the lymph nodes, lungs, liver, or bones. With the aid of imaging studies, including functional hybrid imaging and further medical examination, a primary tumor can be discovered in up to 40% of patients initially diagnosed with CUP. Immunohistochemistry guided by histomorphology often enables precise characterization of the lesion and can be supplemented, in selected cases, by molecular-genetic diagnostic evaluation. The most commonly detected types of primary tumor are cancers of the lung, pancreas, liver, and biliary system. For patients with local metastases, surgical resection or radiotherapy with curative intent is usually indicated, sometimes in the framework of a multimodal treatment concept. The median 2-year survival of patients with disseminated CUP is only 20%. For such patients, specific types of systemic therapy are recommended on the basis of the diagnostic characterization of the disease. Immune-modulatory antibodies can be effective, particularly in the treatment of CUP that has been characterized with biomarkers, but should still be considered experimental at present. A combination of conventional and innovative diagnostic methods enables the provision of highly refined therapeutic strategies to patients with CUP who are undergoing treatment in interdisciplinary cancer centers.

    Full Text Available (1 Background: The purpose of this retrospective study was to evaluate the recurrence and survival rates of metastatic melanoma of unknown primary origin (MUP, in order to further refine current recommendations for the surgical treatment; (2 Methods: Medical data of all MUP patients registered between 2000 and 2011, were analyzed. Seventy-eight patients were categorized in either lymph node (axilla, groin, head-and neck or subcutaneous MUP. Axillary node MUPs were generally treated with dissections of levels I-III, inguinal node MUPs with combined superficial and deep groin dissections, and head-and-neck node MUPs with neck dissections to various extents, based on lymph drainage patterns. Subcutaneous lesions were excised with 1–2 cm margins. The primary outcome was treatment outcomes in terms of (locoregional recurrence and survival rates; (3 Results: Lymph node MUP recurred regionally in 11% of patients, with an overall recurrence rate of 45%. In contrast, subcutaneous MUP recurred locally in 65% of patients with an overall recurrence rate of 78%. This latter group had a significantly shorter disease-free interval than patients with lymph node MUP (p = 0.000. In the entire study population, 5-year and 10-year overall survival rates were 56% and 47% respectively, with no differences observed between the various subgroups; (4 Conclusion: The relatively low regional recurrence rate after regional lymph node dissection (11% supports its current status as standard surgical treatment for lymph node MUP. Subcutaneous MUP, on the contrary, appears to recur both locally (65% and overall (78% at a significantly higher rate, suggesting a different biological behavior. However, wide local excision remains the best available option for this specific group.

    The term cancer of unknown primary (CUP) encompasses a group of entities which differ to a great extent regarding etiology, prognosis and therapeutic management. The aim of the study was an elaboration of the role of radiotherapy in CUP syndrome. Systematic literature search and specification of the available treatment options. Radiotherapy is an integral part of interdisciplinary management approaches for patients with CUP in both curative and palliative situations. Radio-oncological techniques, such as intensity-modulated radiotherapy and stereotactic body radiotherapy increase the therapeutic window. Modern diagnostic modalities from radiology and nuclear medicine are the cornerstone of radiotherapeutic interventions, especially in terms of target volume definition and pretherapeutic staging. In the interdisciplinary setting radiation oncology offers the possibility of curative and often organ preserving approaches in patients with axillary and cervical CUP. In addition, improvement and preservation of quality of life can be achieved in patients with metastatic disease. Radiation oncology is a crucial component of the interdisciplinary management of patients with CUP. Therapeutic decisions in patients with CUP should be made in an interdisciplinary setting. (orig.)

    Full Text Available 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 bladder represent a challenge both to the pathologist and urologists for its diagnosis and treatment, respectively.

    Full Text Available Squamous cell carcinoma (SCC arising from odontogenic cyst lining is rare. The exact incidence of carcinoma arising in odontogenic cyst is unknown, but it is estimated to vary between 1 and 2/1000. The pathogenesis is unknown, but a long-standing inflammation and continuous intracystic pressure have been suggested as possible causative factors. Metastasis from these lesions is not common (< 20%, and most of the carcinomas are moderately to well differentiated. To qualify as a primary intraosseous carcinoma, there must be no initial connection with the oral mucosa, overlying skin, or antral or nasal mucosa. This paper presents a case of primary intraosseous carcinoma arising from odontogenic keratocyst in the anterior mandible with metastasis to left parotid lymph nodes.

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

    Primary intraosseous carcinoma (PIOC) is a rare odontogenic carcinoma defined as a squamous cell carcinoma arising within a jaw having no initial connection with the oral mucosa, and presumably developing from residues of the odontogenic epithelium. A 56-year-old patient who complained of delayed healing after extraction of upper left central incisor visited our department. The conventional radiographs showed a bony destructive lesion with ill-defined margin and moth-eaten appearance. On the computed tomographic images, the lesion perforated the labial cortex of alveolar bone, elevated the left nasal floor superiorly, and perforated partially both nasal floor. The magnetic resonance images showed low signal intensity at T2 and T1 weighted images at the area and adjacent soft tissue. Histologically, there were irregular epithelial islands with cell atypia, nuclear hyperchromatism, pleomorphism, atypical mitosis. The final diagnosis was PIOC.

    2008-01-01

    Purpose: To compare the effectiveness of intensity-modulated radiotherapy (IMRT) and conventional (two-dimensional) radiotherapy in the treatment of cervical lymph node metastases from unknown primary cancer (UPC). Methods and Materials: Between February 2003 and September 2006, 23 patients with UPC of squamous cell carcinoma were treated with IMRT. Extended putative mucosal and bilateral nodal sites were irradiated to a median dose of 66 Gy. In 19 patients, IMRT was performed after lymph node dissection, and in 4 patients primary radiotherapy was given. The conventional radiotherapy group (historical control group) comprised 18 patients treated to a median dose of 66 Gy between August 1994 and October 2003. Results: Twenty patients completed treatment. As compared with conventional radiotherapy, the incidence of Grade 3 acute dysphagia was significantly lower in the IMRT group (4.5% vs. 50%, p = 0.003). By 6 months, Grade 3 xerostomia was detected in 11.8% patients in the IMRT group vs. 53.4% in the historical control group (p = 0.03). No Grade 3 dysphagia or skin fibrosis was observed after IMRT but these were noted after conventional radiotherapy (26.7%, p = 0.01) and 26.7%, p = 0.03) respectively). With median follow-up of living patients of 17 months, there was no emergence of primary cancer. One patient had persistent nodal disease and another had nodal relapse at 5 months. Distant metastases were detected in 4 patients. The 2-year overall survival and distant disease-free probability after IMRT did not differ significantly from those for conventional radiotherapy (74.8% vs. 61.1% and 76.3% vs. 68.4%, respectively). Conclusions: Use of IMRT for UPC resulted in lower toxicity than conventional radiotherapy, and was similar in efficacy

    Full Text Available We report a unique case of combined primary neuroendocrine carcinoma (NEC and hepatocellular carcinoma (HCC of the liver in a 65-year-old male patient. The patient underwent segmental resection of the liver and regional lymph node dissection for a tumor mass that measured 7.5 cm in diameter in the right lobe, with regional lymphadenopathy. Histologically, the hepatic tumor was composed of predominantly small-cell NEC, but admixed with a small island of moderately differentiated HCC. We speculate that the NEC originated from a poorly differentiated tumor clone of an HCC that underwent neuroendocrine differentiation, and that this tumor was now at the end stage of the transitional period from HCC to NEC, based on the small amount of disappearing HCC. Ki-67 and p53 expression were higher in the NEC than in the HCC, and the lymph nodes showed only metastatic NEC. Therefore, this kind of tumor had a more aggressive clinical course in accordance with being an NEC rather than a conventional HCC. Three months after operation, the patient had multiple recurrent tumor nodules within the liver, spreading the metastasis to the adrenal glands and para-aortic lymph nodes. The patient died 1 year after operation.

We conducted a retrospective multi-institutional case series including all patients diagnosed with an unknown primary HNSCC who underwent TORS to identify the primary site from January 1, 2010 to June 30, 2016. We excluded those with recurrent disease, ≤6months of follow up from TORS, previous history of radiation therapy (RT) to the head and neck, or evidence of primary tumor site based on previous biopsies. Our main outcome measure was receipt of post-operative therapy. The tumor was identified in 26/35 (74.3%) subjects. Post-TORS, 2 subjects did not receive adjuvant therapy due to favorable pathology. Volume reduction of RT mucosal site coverage was achieved in 12/26 (46.1%) subjects who had lateralizing tumors, ie. those confined to the palatine tonsil or glossotonsillar sulcus. In addition, for 8/26 (30.1%), the contralateral neck RT was also avoided. In 9 subjects, no primary was identified (pT0); four of these received RT to the involved ipsilateral neck nodal basin only without pharyngeal mucosal irradiation. Surgical management of an unknown primary with TORS can lead to deintensification of adjuvant therapy including avoidance of chemotherapy and reduction in RT doses and volume. There was no increase in short term treatment failures. Treatment after TORS can vary significantly, thus we advocate adherence to NCCN guideline therapy post-TORS to avoid treatment-associated variability. Published by Elsevier Ltd.

    Neuroendocrine tumors (NETs) with unknown primary (CUP-NET) are associated with a poor prognosis (10-year survival 22 %), grade 1 and 2 NETs having a more favorable outcome than grade 3 (also called carcinoma). There is evidence that an effort should be made to localize the primary tumor even in the presence of metastasis because resection of the primary tumor(s) may improve disease-free and overall survival, and because the choice of chemotherapeutic agent depends on the location of the primary tumor. Localization of the tumors remains challenging and often relies on a combination of radiological, endoscopic and functional imaging. The functional imaging protocol for evaluation of these patients has historically relied on somatostatin receptor scintigraphy (SRS). However, the sensitivity and specificity of SRS may be unsatisfactory, especially for NETs of midgut origin. Newer PET radiotracers such as {sup 68}Ga-labeled somatostatin analogs ({sup 68}Ga-DOTA-SSTa) and {sup 18}F-DOPA have shown promise. In direct comparisons between {sup 68}Ga-DOTA-SSTa PET/CT and {sup 99m}Tc-HYNIC-octreotide/{sup 111}In-pentetreotide SPECT(/CT), {sup 68}Ga-DOTA-SSTa performed better than other techniques, giving a compelling reason for switching from SPECT/CT to PET/CT imaging. {sup 18}F-DOPA performs better than SRS and CT in well-differentiated NETs of the small intestine. For detecting pancreatic NETs, the high background uptake of {sup 18}F-DOPA by the normal exocrine pancreas can be somewhat overcome by pretreatment with carbidopa. We have suggested a protocol in which SRS is replaced by one of the two agents (preferably with {sup 68}Ga-DOTA-SSTa, alternatively {sup 18}F-DOPA) as first-line nuclear tracer for detection of CUP-NET in patients with well-differentiated NETs and {sup 18}F-FDG PET/CT may be an additional diagnostic test for poorly differentiated tumors and for prognostication.

    Adenosquamous carcinoma, a rare malignant tumor of the stomach, is characterized by the presence of two different cell components, one adenomatous and the other squamous. Adenosquamous carcinoma of the stomach tends to more aggressive clinicopathologic features than common adenocarcinoma. There are few reports about radiologic features of adenosquamous carcinoma of the stomach. We experienced a case of a primary adenosquamous carcinoma of the stomach in a 67-year-old man, and report here the ultrasonographic and computed tomographic (CT) findings

    Operative treatment offers the best chance for long term survival in lung cancer of early stage. In the same way surgery may be the most efficient treatment of lung metastases from tumors of extrapulmonary site. The preoperative investigations have to prove that in case of lung cancer this is restricted to one hemithorax and in lung metastases that these are restricted to the lungs exclusively. They also have to prove that the lung function allows adequate resection. This is mainly lobectomy and pneumonectomy, sometimes sleeve resection and rarely segmentectomy for primary lung cancers. Resection of metastases preferably is by wedge excision or enucleation. In bilateral lesions median sternotomy is the favoured approach to both lungs in a single session. Long term results in primary lung cancer depend on the tumor stage. As a rule of thumb by each step of tumor stage the 5-year-survival rate is cut to half. In regard to histology small cell undifferentiated carcinomas are considered surgical indications only in the very early stage and need to be treated by adjuvant chemotherapy. The operative mortality is correlated to the extent of resection and by average is higher for primary carcinoma of the lung because of the usually higher age level and additional pulmonary damage. Patients operated for pulmonary metastases, however, are in lower age range and due to less functional risks, the operative mortality in most series is between 0 and 3%. Early detection of lung cancer, i.e., immediate and expert exploration of suspicious X-ray findings or respiratory symptoms particularly in smokers and with asbestos exposed individuals will contribute to an increasing efficacy of surgical treatment.

    In order to detect and to evaluate the frequency, the distribution, and the radiological findings of skeletal metastases from hepatocellular carcinoma, the authors retrospectively analyzed radiographic, scintigraphic, and CT findings of 257 patients with hepatocellular carcinoma. The results were as follows: 1. Skeletal metastases were demonstrated in 21 patients (8.2%). 2. Frequent symptoms were pain, limitation of motion, paralysis, and mass. In nine of them the initial symptoms were due to skeletal metastases. 3. The common sites of metastases were spine (13 cases), ribs (8 cases), pelvis (8 cases) and femur (6 cases). Humerus, skull and sternum were also frequently involved. 4. Plain film findings were purely osteolytic in all cases and pathologic fractures were noted in 5 cases. 5. The lesions appear expansible in 7 cases, and 4 of them showed associated soft tissue masses on CT scans. 6. Bone scans were performed in 13 cases of them and showed increased radiotracer uptake in all. 7. Angiographic studies of 3 cases showed hypervascularity of the metastatic lesions as well as the primary hepatic tumor.

    Forty-three cases of primary vaginal squamous cell cancer were treated at the University of Wisconsin Hospital between 1956 and 1971. These cases comprised of 1.2% of patients admitted to the University Hospital with female genital tract cancer. Evidence is presented to support a modification of the currently accepted FIGO staging system for vaginal carcinoma (Stage II disease). Radiation therapy using both external beam and brachyradium equivalents or interstitial implantation of suitable isotopes was an effective method for the treatment of patients having early and locally advanced invasive vaginal cancer. The 5-year absolute survival rate for the entire series was 37.2%. Absolute survival rate by modified FIGO clinical staging was 66% for Stages I and IIA, 31% for Stage IIB, 25% for Stage III, and 0% for Stage IV

    Full Text Available Hydatic cyst is an illness that appears in consequence of the cystic form of small strap-shaped worm Echinococcus granulosis. Frequently, cysts exist in the lungs and liver. Peritoneal involvement is rare, and generally occurs as a result of second inoculation from rupture of a liver-located hydatic cyst. Primary ovarian hydatic cyst is very rare. A 56-year-old female patient was admitted to Emergency Service with the complaint of stomachache and swollen abdomen. From ultrasonographic examination, a right ovarian 52 × 45-mm heterogeneous semi-solid cystic mass and right hydronephrosis were detected. As a result of the tomographic examination, the right ovarian growth was judged to be a 60 × 45-mm lobule contoured, septal, heterogeneously cystic mass (ovarian carcinoma. Depending on these indicators and with the diagnosis of ovarian carcinoma, laparotomy was planned. During the observation, a mass that compressed on the right ureter and dilatation in the right ureter were determined. The mass was approximately 6 cm long and smoothly contoured, including widespread adhesions, and also obliteration of the pouch of Douglas. The mass was excised and total abdominal hysterectomy and bilateral salpingo-oopherectomy performed. After a pathological examination, hydatid cyst was diagnosed. Although pointing at the issue of the distinctive diagnosis of pelvic and peritoneal mass, it should be realized that the existence of primary peritoneal and pelvic involvement of the hydatic cyst is generally a result of the second inoculation, and is also more common in regions in which Echinococcus granulosa is endemic and livestock production is prevalent.

    Purpose: To determine the effectiveness and rate of complications of intensity-modulated radiotherapy (IMRT) in the treatment of cervical lymph node metastases from unknown primary cancer. Methods and Materials: Between February 2005 and November 2008, 25 patients with an unknown primary cancer underwent IMRT, with a median radiation dose of 70 Gy. The bilateral neck and ipsilateral putative pharyngeal mucosa were included in the target volume. All patients had squamous cell carcinoma, except for 1 patient who had adenosquamous differentiation. They were all treated with curative intent. Of the 25 included patients, 20 were men and 5 were women, with a median age of 54 years. Of these patients, 3 had Stage III, 18 had Stage IVa, and 4 had Stage IVb. Of the 25 patients, 18 (72%) received platinum-based chemotherapy in a combined-modality setting. Neck dissection was reserved for residual disease after definitive IMRT. Overall survival, disease-free survival, and locoregional control were calculated using the Kaplan-Meier method. Results: With a median follow-up of 38 months, the overall survival, disease-free survival, and locoregional control rates were all 100% at 3 years. No occurrence of primary cancer was observed during the follow-up period. The reported rates of xerostomia reduced with the interval from the completion of treatment. Nine patients (36%) reported Grade 2 or greater xerostomia at 6 months, and only 2 (8%) of them reported the same grade of salivary function toxicity after 24 months of follow-up. Conclusion: In our institution, IMRT for unknown primary cancer has provided good overall and disease-free survival in all the patients with an acceptable rate of complications. IMRT allowed us to address the bilateral neck and ipsilateral putative pharyngeal mucosa with minimal late salivary function toxicity. The use of concurrent chemotherapy and IMRT for more advanced disease led to good clinical results with reasonable toxicities.

    Carcinoma of unknown primary (CUP) is a heterogeneous group of histologically proven metastatic malignancies for which the primary tumor could not be detected despite thorough diagnostic evaluation. CUP accounts for 2.3-4.2% of cancer in both sexes and follows an aggressive behavior with a median survival less than 1 year. Identification of a primary tumor has an impact on therapy and life expectancy and it is often detected only in 10-35% of all cases by conventional imaging modalities. Hence there is clearly a need of whole body, non invasive imaging modality with a high diagnostic yield

    Peritoneum is a site for both primary and secondary tumors. Primary peritoneal tumors are fairly rare. The most common primary tumors of the peritoneum are malignant mesothelioma and serous papillary adenocarcinoma. Clear cell carcinoma of the peritoneum is extremely rare and often misdiagnosed as mesothelioma, serous carcinoma, or metastatic adenocarcinoma, so it represents a diagnostic challenge for both clinicians and pathologists. Up to date, to the best of our knowledge, only 11 cases of primary peritoneal clear cell carcinoma have been reported in the English literature. Distinguishing this tumor of the peritoneum versus ovarian carcinoma can be problematic. Herein, we report a rare case of primary peritoneal clear cell carcinoma occurring in a 49-year-old woman, along with a review of the literature. © The Author(s) 2015.

    Minimal information has been published about the results of palliative irradiation for squamous cell carcinoma metastatic to cervical lymph nodes from an unknown head and neck primary site. Forty patients with this diagnosis were treated at the University of Florida with radiation therapy with palliative intent. The nodal response rate was 65% and the symptomatic response rate was 57% at 1 year. The absolute survival rate was 25% at 1 year, as was the cause-specific survival rate. Radiotherapy successfully palliates more than half of those treated. Approximately one fourth are alive 1 year after irradiation

    Full Text Available Cancer complicates approximately 0.1% of all pregnancies. Primary tracheal carcinoma is one of very rarely seen tumors and the rate of its being seen makes up approximately % 0,2 of all tumors of respiratory tract. The patient, 28 years old, who has 28-weeks-pregnant, was diagnosed with primary tracheal adenocystic carcinoma. Patient was made operation as thoracotomy and tracheal tumor was removed at the 28th week of pregnancy. Patient was delivered with sectio abdominale at the 39th week of pregnancy. Primary tracheal adenocystic carcinoma is very rarely seen tumors and it is the first tracheal ACC with pregnancy case in literature to have been detected and surgically treated during pregnancy. We discussed primary tracheal adenocystic carcinoma and tracheal tumors during pregnancy with literature.

    Purpose: To compare differences in dosimetric, clinical, and quality-of-life endpoints among a cohort of patients treated by intensity-modulated radiotherapy (IMRT) and conventional radiotherapy (CRT) for head-and-neck cancer of unknown primary origin. Methods and Materials: The medical records of 51 patients treated by radiation therapy for squamous cell carcinoma of the head and neck presenting as cervical lymph node metastasis of occult primary origin were reviewed. Twenty-four patients (47%) were treated using CRT, and 27 (53%) were treated using IMRT. The proportions of patients receiving concurrent chemotherapy were 54% and 63%, respectively. Results: The 2-year estimates of overall survival, local-regional control, and disease-specific survival for the entire patient population were 86%, 89%, and84%, respectively. There were no significant differences in any of these endpoints with respect to radiation therapy technique (p > 0.05 for all). Dosimetric analysis revealed that the use of IMRT resulted in significant improvements with respect to mean dose and V30 to the contralateral (spared) parotid gland. In addition, mean doses to the ipsilateral inner and middle ear structures were significantly reduced with IMRT (p < 0.05 for all). The incidence of severe xerostomia in the late setting was 58% and 11% among patients treated by CRT and IMRT, respectively (p < 0.001). The percentages of patients who were G-tube dependent at 6 months after treatment were 42% and 11%, respectively (p < 0.001). Conclusions: IMRT results in significant improvements in the therapeutic ratio among patients treated by radiation therapy for head-and-neck cancer of unknown primary origin.

    Time to treatment and pretreatment costs may be affected by unknown primary tumor site. This retrospective study used electronic medical record data from patients in ten US community oncology practices. Eligible patients were ≥18 years, diagnosed with cancer of unknown primary (CUP) or known metastatic solid tumor, and presented between 1 January 2012 and 30 June 2014. Patients with CUP (n = 294) had a longer interval than non-CUP patients (n = 92) from presentation to treatment initiation (1.18 vs 0.49 months, p < 0.0001), and had higher pretreatment costs (US$27,882 vs US$20,449, p = 0.0075). When analyzed as monthly cost, the difference between groups in log-cost per month was nonsignificant. Higher pretreatment costs in CUP patients appeared attributable to significantly longer time to initiation of therapy.

    Full Text Available Primary peritoneal serous carcinoma (PPSC is a rare primary malignancy that diffusely involves the peritoneum, indistinguishable clinically and histopathologically from primary serous ovarian carcinoma. The origin of PPSC has not been well characterized. Here we present a case of PPSC diagnosed in ultrasonography-guided fine needle aspiration cytology (FNAC in a 76- old female presenting with ascites, abdominal pain, distension and constipation. PPSC is an unusual tumour but cytomorphology is distinctive enough to diagnose preoperatively. In the case report hereby described PPSC is an inoperable malignancy, hence chemotherapy and palliative care are the only offered treatment.

    Full Text Available Abstract Background Cancer of unknown primary site (CUP is considered an aggressive metastatic disease but whether the prognosis differs from metastatic cancers of known primary site is not known. Such data may give insight into the biology of CUP and the metastatic process in general. Methods 6,745 cancer patients, with primary metastatic cancer at diagnosis, were identified from the Swedish Cancer Registry, and were compared with 2,881 patients with CUP. Patients were diagnosed and died between 2002 and 2008. The influence of the primary site, known or unknown, on survival in patients with metastases at specific locations was investigated. Hazard ratios (HRs of death were estimated for several sites of metastasis, where patients with known primary sites were compared with CUP patients. Results Overall, patients with metastatic cancers with known primary sites had decreased hazards of death compared to CUP patients (HR = 0.69 [95% CI = 0.66–0.72]. The exceptions were cancer of the pancreas (1.71 [1.54–1.90], liver (1.58 [1.36–1.85], and stomach (1.16 [1.02–1.31]. For individual metastatic sites, patients with liver or bone metastases of known origin had better survival than those with CUP of the liver and bone. Patients with liver metastases of pancreatic origin had an increased risk of death compared with patients with CUP of the liver (1.25 [1.06–1.46]. The median survival time of CUP patients was three months. Conclusions Patients with CUP have poorer survival than patients with known primaries, except those with brain and respiratory system metastases. Of CUP sites, liver metastases had the worst prognosis. Survival in CUP was comparable to that in metastatic lung cancer. The aggressive behavior of CUP may be due to initial immunosuppression and immunoediting which may allow accumulation of mutations. Upon escape from the suppressed state an unstoppable tumor spread ensues. These novel data on the epidemiology of the

    Multiple malignant esophageal tumors of the same cell type are described. In the esophageal mucosa, widespread carcinomatous transformation may be observed and multicentric invasive squamous cell carcinomas may develop. The concomitance of two independent esophageal malignant neoplasms of different epithelial histogenesis is uncommon. Synchronous adenocarcinoma and squamous cell carcinoma of the esophagus is reported. Adenosquamous carcinoma of the esophagus is a rare tumor. Adenocarcinoma of the esophagus represents 10% of esophageal cancer. We report a case of a synchronous primary invasive adenosquamous carcinoma and adenocarcinoma of the esophagus. Both tumors were demonstrated radiographically. The peculiarity of this neoplastic association and the importance of complete radiographic esophageal evaluation in patients with one obvious obstructing tumor of the esophagus are emphasized.

    Urethral carcinoma in women is uncommon. This study was undertaken to evaluate the role of radiotherapy in the treatment of these tumors. The hospital records of 34 women with primary urethral carcinoma were retrospectively reviewed. There were 15 squamous cell carcinomas, 13 transitional cell carcinomas, and six adenocarcinomas. The primary tumor was >4 cm in size in eight patients, involved the proximal urethra in 19 and extended to adjacent organs in 22. Inguinal or iliac lymphadenopathy was present in nine patients. There were eight TNM stage I/II tumors, 11 stage III tumors and 15 stage IV tumors. Radiotherapy was administered only to the primary tumor in 15 patients, and to the primary tumor and regional lymph nodes in the remaining 19 patients. Brachytherapy with or without external radiation was used to treat the primary tumor in 20 patients. Tumor recurred in 21 patients. The 7-year actuarial overall and cause-specific survivals were 41 and 45%, respectively. Large primary tumor bulk and treatment with external beam radiation alone (no brachytherapy) were independent adverse prognostic factors for local tumor recurrence. Brachytherapy reduced the risk of local recurrence by a factor of 4.2. The beneficial effect of brachytherapy was most prominently seen in patients with bulky primary disease. Large tumor size was the only independent adverse predictor of overall disease recurrence and death from cancer. Radiotherapy is an effective treatment for carcinoma of the female urethra and preserves normal anatomy and function. Brachytherapy improves local tumor control, possibly as a result of the higher radiation dose that can safely be delivered. (author)

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

    Purpose: No single standard treatment paradigm is available for head-and-neck squamous cell carcinoma of an unknown primary (HNCUP). Bilateral neck radiotherapy with mucosal axis irradiation is widely used, with or without chemotherapy and/or surgical resection. Intensity-modulated radiotherapy (IMRT) is a highly conformal method for delivering radiation that is becoming the standard of care and might reduce the long-term treatment-related sequelae. We report the Dana-Farber Cancer Institute experience with IMRT-based treatment for HNCUP. Patients and Materials: A retrospective study of all patients treated at the Dana-Farber Cancer Institute for HNCUP with IMRT between August 2004 and January 2009. The primary endpoint was overall survival; the secondary endpoints were locoregional and distant control, and acute and chronic toxicity. Results: A total of 24 patients with HNCUP were included. Of these patients, 22 had Stage N2 disease or greater. All patients underwent neck computed tomography, positron emission tomography-computed tomography, and examination under anesthesia with directed biopsies. Of the 24 patients, 22 received concurrent chemotherapy, and 7 (29%) also underwent induction chemotherapy. The median involved nodal dose was 70 Gy, and the median mucosal dose was 60 Gy. With a median follow-up of 2.1 years, the 2-year actuarial overall survival and locoregional control rate was 92% and 100%, respectively. Only 25% of the patients had Grade 2 xerostomia, although 11 patients (46%) required esophageal dilation for stricture. Conclusion: In a single-institution series, IMRT-based chemoradiotherapy for HNCUP was associated with superb overall survival and locoregional control. The xerostomia rates were promising, but the aggressive therapy was associated with significant rates of esophageal stenosis.

    The term cancer of unknown primary (CUP) encompasses a group of entities which differ to a great extent regarding etiology, prognosis and therapeutic management. The aim of the study was an elaboration of the role of radiotherapy in CUP syndrome. Systematic literature search and specification of the available treatment options. Radiotherapy is an integral part of interdisciplinary management approaches for patients with CUP in both curative and palliative situations. Radio-oncological techniques, such as intensity-modulated radiotherapy and stereotactic body radiotherapy increase the therapeutic window. Modern diagnostic modalities from radiology and nuclear medicine are the cornerstone of radiotherapeutic interventions, especially in terms of target volume definition and pretherapeutic staging. In the interdisciplinary setting radiation oncology offers the possibility of curative and often organ preserving approaches in patients with axillary and cervical CUP. In addition, improvement and preservation of quality of life can be achieved in patients with metastatic disease. Radiation oncology is a crucial component of the interdisciplinary management of patients with CUP. Therapeutic decisions in patients with CUP should be made in an interdisciplinary setting. (orig.)

    Background and purpose: up to 10% of all neck lymph node metastases present without a known primary site. The optimal treatment strategy for these patients is still undefined. The purpose of this retrospective analysis is to assess the outcome in patients with neck metastases from an unknown primary tumor (CUP). Furthermore, prognostic factors and treatment modalities are discussed. Patients and methods: from 1984 to 2003, 28 patients with squamous cell neck metastases from a CUP were treated at the authors' institution. In 17 patients, neck dissection (twelve radical, five modified radical) was performed. In that case, adjuvant radiotherapy was carried out with a mean of 56.7 Gy. In eleven patients, only biopsies were done. These patients received definitive radiotherapy with a mean of 66.8 Gy. In summary, 25 patients received extended radiotherapy including both sides of the neck and potential mucosal primary sites. Additional chemotherapy was administered to five patients. Results: the duration of follow-up was 4.1-189.5 months (median 45.1 months). After this period of time, ten patients (36%) remained alive. 5-year overall survival was 40.1%, neck control rate 72.7%. No subsequent primary could be detected. Extracapsular extension and surgery had significant influence on prognosis. Grade 3 toxicity (mucositis or skin reactions) was seen in three patients; no hematologic toxicity > grade 2 was observed. 19 patients suffered from grade 2 xerostomia. Conclusion: with radical surgery followed by radiotherapy good survival rates in patients with neck metastases from a CUP can be obtained. Whether limited radiotherapy might be equal to extended irradiation and can reduce side effects, must be shown in ongoing clinical trials. (orig.)

    Eight patients with undifferentiated carcinoma of the esophagus were treated by radiation therapy. Loco-regional control was easily achieved by radiation therapy alone and no loco-regional recurrence was observed for six patients treated with total dose of more than 30 Gy. However four patients developed distant metastases and died of tumor. Median survival was 3.5 months with a range of 0 to 48 months. Only one patient is alive with no evidence of tumor for 48 months. Combination chemotherapy should be recommended for primary undifferentiated carcinoma of the esophagus because of having a high incidence of distant metastases. (author)

    Head and neck cancer of unknown primary (HNCUP) is rare and prospective studies are lacking. The impact of different prognostic factors such as age and N stage is not completely known, the optimal treatment is not yet established, and the reported survival rates vary. In the last decade, human papilloma virus (HPV) has been identified as a common cause of and important prognostic factor in oropharyngeal cancer, and there is now growing interest in the importance of HPV for HNCUP. The aim of the present study on curatively treated HNCUP was to investigate the prognostic importance of different factors, including HPV status, treatment, and overall survival. A search for HNCUP was performed in the Swedish Cancer Registry, Western health district, between the years 1992-2009. The medical records were reviewed, and only patients with squamous cell carcinoma or undifferentiated carcinoma treated with curative intent were included. The tumor specimens were retrospectively analyzed for HPV with p16 immunostaining. Sixty-eight patients were included. The mean age was 59 years. The majority were males, and had N2 tumors. Sixty-nine percent of the tumors were HPV positive using p16 staining. Patients who were older than 70 years, patients with N3-stage tumors, and patients with tumors that were p16 negative had a significantly worse prognosis. The overall 5-year survival rate for patients with p16-positive tumors was 88% vs 61% for p16-negative tumors. Treatment with neck dissection and postoperative radiation or (chemo) radiation had 81 and 88% 5-year survival rates, respectively. The overall and disease-free 5-year survival rates for all patients in the study were 82 and 74%. Curatively treated HNCUP had good survival. HPV infection was common. Independent prognostic factors for survival were age over 70 years, HPV status and N3 stage. We recommend that HPV analysis should be performed routinely for HNCUP. Treatment with neck dissection and postoperative radiation or

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

    Adenocarcinoma of unknown primary (AUP) has generally a poor prognosis. Previous studies have suggested that Cisplatin and Etoposide have activity in AUP. The aim of this study was to determine if dose intensification of this combination would result in increased efficacy. Each 28 day cycle consisted of Cisplatin 100 mg/m2 given on Day 1 and 8 with Etoposide 80 mg/m2 given on day 1, 2, 8 and 9. Sixteen patients (Pts) with no prior chemotherapy were accrued to this study. Predominant sites of disease were lung, liver, and bone. BHCG and AFP were not elevated. One complete remission was seen in a patient with a mediastinal mass (duration of remission = 59 weeks). Two other patients had a partial response. Overall response rate was 19%. Moderate to severe renal toxicity was recorded in 8 patients, with neuro- and ototoxicities in 2 patients each. Severe granulocytopenia occurred in 8 patients, and one patient died of congestive heart failure on day 1 of cycle 2. This excessive toxicity, without enhanced efficacy does not encourage a more extensive empiric trial by this dose schedule in the treatment of AUP.

    To determine MR features suggestive of mass-forming cholangiocarcinoma (CCA) or liver metastases of adenocarcinoma of unknown primary (AUP), and to compare the ability of two experienced radiologists to establish the correct diagnosis. 61 patients with CCA or AUP, with MRIs were placed into two groups: population 1, 28 patients with certain diagnosis of either CCA or AUP; and population 2, 33 patients with uncertain diagnosis. Using population 1 with known diagnosis, two investigators formulated imaging criteria for CCA or AUP, which represented phase 1 of the study. In phase 2, two independent radiologists categorized the patients in populations 1 and 2 as CCA or AUP using the formulated criteria. This categorization was compared with the patient medical records and pathologist review. Findings were tested for statistical significance. In phase 1, solitary lesion, multifocal lesions with dominant lesion, capsule retraction, and porta hepatis lymphadenopathy were features of CCA; multifocal lesions with similar size, and ring enhancement were features of AUP. The number of lesions, capsule retraction, and early tumor enhancement pattern were observed to be significant features (P AUP are identifiable on MRI images, which may aid the radiologist to establish the correct diagnosis.

    A rat monoclonal antibody, YPC2/38.8, was selected from a panel of antibodies derived by immunising rats with fresh human colorectal carcinoma. It was found to bind to a 30,000 dalton protein present on the cell surface of normal colon and liver. This protein was increased 10-fold on primary hepatocellular carcinoma (PHC) cells. After labelling with /sup 131/I, YPC2/38.8 was shown to localise human PHCs grown as xenografts in immunosuppressed mice. The authors conclude that YPC2/38.8 may have potential for diagnostic localisation and possibly thence for the selective targeting of drugs or toxins in patients with PHC arising in a liver unaffected by significant parenchymal disease. 16 refs.; 4 figs.; 1 table.

    To explore the added value of histogram analysis of apparent diffusion coefficient (ADC) values over magnetic resonance (MR) imaging and fluorine 18 ((18)F) fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) for the detection of occult palatine tonsil squamous cell carcinoma (SCC) in patients with cervical nodal metastasis from a cancer of an unknown primary site. The institutional review board approved this retrospective study, and the requirement for informed consent was waived. Differences in the bimodal histogram parameters of the ADC values were assessed among occult palatine tonsil SCC (n = 19), overt palatine tonsil SCC (n = 20), and normal palatine tonsils (n = 20). One-way analysis of variance was used to analyze differences among the three groups. Receiver operating characteristic curve analysis was used to determine the best differentiating parameters. The increased sensitivity of histogram analysis over MR imaging and (18)F-FDG PET/CT for the detection of occult palatine tonsil SCC was evaluated as added value. Histogram analysis showed statistically significant differences in the mean, standard deviation, and 50th and 90th percentile ADC values among the three groups (P histogram analysis was 52.6% over MR imaging alone and 15.8% over combined conventional MR imaging and (18)F-FDG PET/CT. Adding ADC histogram analysis to conventional MR imaging can improve the detection sensitivity for occult palatine tonsil SCC in patients with a cervical nodal metastasis originating from a cancer of an unknown primary site. © RSNA, 2015.

    Primary fallopian tube carcinoma (PFTC) is a rare tumour of the female genital tract with an incidence of 0.1-1.8% of all genital malignancies, and it is very difficult to diagnose preoperatively, because of its non-specific symptomatology. In most cases, it is an intraoperative finding or a histopathological diagnosis. It is a tumour that histologically and clinically resembles epithelial ovarian cancer. We are reporting a case of a 62-year-old, postmenopausal women with primary fallopian tube carcinoma of the right fallopian tube in stage IA. The patient has lower abdominal pain, watery vaginal discharge and repeated episodes of bleeding from the vagina. The clinical and radiological findings suggested a right adnexal tumour with elevated CA-125 levels. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy and peritoneal washing were performed. Pathologic confirmation of primary serous cystadenocarcinoma of the right fallopian tube was made. Peritoneal washings were negative for malignancy. FIGO stage was considered as IA, and the patient received no courses of chemotherapy and postoperative radiation because she refused it. Ten months after initial surgery, the patient is alive and in good condition. Cytoreduction surgery followed by adequate cycles of chemotherapy is an important strategy to improve patients' prognosis.

    While fibroblast growth factor receptor 3 (FGFR3) is frequently mutated or overexpressed in nonmuscle-invasive urothelial carcinoma (UC), the prevalence of FGFR3 protein expression and mutation remains unknown in muscle-invasive disease. FGFR3 protein and mRNA expression, mutational status, and copy number variation were retrospectively analyzed in 231 patients with formalin-fixed paraffin-embedded primary UCs, 33 metastases, and 14 paired primary and metastatic tumors using the following methods: immunohistochemistry, NanoString nCounterTM, OncoMap or Affymetrix OncoScanTM array, and Gain and Loss of Analysis of DNA and Genomic Identification of Significant Targets in Cancer software. FGFR3 immunohistochemistry staining was present in 29% of primary UCs and 49% of metastases and did not impact overall survival (P = 0.89, primary tumors; P = 0.78, metastases). FGFR3 mutations were observed in 2% of primary tumors and 9% of metastases. Mutant tumors expressed higher levels of FGFR3 mRNA than wild-type tumors (P < 0.001). FGFR3 copy number gain and loss were rare events in primary and metastatic tumors (0.8% each; 3.0% and 12.3%, respectively). FGFR3 immunohistochemistry staining is present in one third of primary muscle-invasive UCs and half of metastases, while FGFR3 mutations and copy number changes are relatively uncommon

    Background: Identification of primary tumor in patients with cervical lymph node metastasis of unknown primary (MUO) has a great impact on therapy approach and potentially on patient prognosis. Purpose: To assess the diagnostic accuracy of combined positron emission tomography (PET)/computer tomography (CT) for primary tumor detection in cervical metastases of unknown origin compared to PET, CT, and PET+CT side-by-side evaluation. Material and Methods: 39 consecutive patients (eight women, 31 men; mean age 59.9±11.2 years) with MUO were enrolled in this study. PET/CT images were obtained 1 hour after injection of 350 MBq of fluorodeoxyglucose. Oral and intravenous contrast agents were administered in all patients to ensure diagnostic CT data. Fused PET/CT data were evaluated for primary tumor detection. Diagnostic accuracy was calculated and compared with CT alone, PET alone, and side-by-side PET+CT evaluation. Statistical analysis of differences in diagnostic performance between the different imaging procedures was based on the McNemar test. Results: Fused PET/CT depicted the primary tumor in 11 of 39 (28%) patients. In 28 (72%) patients, the primary tumor remained occult. CT revealed the primary in five (13%), PET alone in 10 (26%), and side-by-side evaluation of PET+CT in 10 (26%) of 39 patients. Statistical analysis showed no significant differences between the imaging modalities. Conclusion: PET, side-by-side PET+CT, and PET/CT revealed similar detection rates for primary tumors in cervical MUO patients. Therefore, cervical metastases of an unknown primary may be assessed with either of these imaging modalities. Detection rates with CT were substantially lower. Thus, inclusion of functional data for assessment of cervical MUO patients must be recommended

    The aim of this study was to systematically review and meta-analyze published data on the diagnostic performance of combined 18F-fluoro-2-deoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) in the detection of primary tumors in patients with cancer of unknown primary (CUP). A systematic search for relevant studies was performed of the PubMed/MEDLINE and Embase databases. Methodological quality of the included studies was assessed. Reported detection rates, sensitivities and specificities were meta-analyzed. Subgroup analyses were performed if results of individual studies were heterogeneous. The 11 included studies, comprising a total sample size of 433 patients with CUP, had moderate methodological quality. Overall primary tumor detection rate, pooled sensitivity and specificity of FDG-PET/CT were 37%, 84% (95% CI 78-88%) and 84% (95% CI 78-89%), respectively. Sensitivity was heterogeneous across studies (P = 0.0001), whereas specificity was homogeneous across studies (P = 0.2114). Completeness of diagnostic workup before FDG-PET/CT, location of metastases of unknown primary, administration of CT contrast agents, type of FDG-PET/CT images evaluated and way of FDG-PET/CT review did not significantly influence diagnostic performance. In conclusion, FDG-PET/CT can be a useful method for unknown primary tumor detection. Future studies are required to prove the assumed advantage of FDG-PET/CT over FDG-PET alone and to further explore causes of heterogeneity. (orig.)

    Purpose: To determine how the addition of cisplatin-based concurrent chemotherapy to radiation therapy influences outcomes among a cohort of patients treated for head-and-neck cancer of unknown primary origin. Methods and Materials: The medical records of 60 consecutive patients treated by radiation therapy for squamous cell carcinoma of the head and neck presenting as cervical lymph node metastasis of occult primary origin were reviewed. Thirty-two patients (53%) were treated by concurrent chemoradiation, and 28 patients (47%) were treated by radiation therapy alone. Forty-five patients (75%) received radiation therapy after surgical resection, and 15 patients (25%) received primary radiation therapy. Thirty-five patients (58%) were treated by intensity-modulated radiotherapy. Results: The 2-year estimates of overall survival, local-regional control, and progression-free survival were 89%, 89%, and 79%, respectively, among patients treated by chemoradiation, compared to 90%, 92%, and 83%, respectively, among patients treated by radiation therapy alone (p > 0.05, for all). Exploratory analysis failed to identify any subset of patients who benefited from the addition of concurrent chemotherapy to radiation therapy. The use of concurrent chemotherapy was associated with a significantly increased incidence of Grade 3+ acute and late toxicity (p < 0.001, for both). Conclusions: Concurrent chemoradiation is associated with significant toxicity without a clear advantage to overall survival, local-regional control, and progression-free survival in the treatment of head-and-neck cancer of unknown primary origin. Although selection bias cannot be ignored, prospective data are needed to further address this question.

    The goal of this study was to evaluate the anti-tumour activity and toxicoses of vinorelbine as a palliative rescue therapy for dogs with primary urinary bladder carcinoma. Thirteen dogs refractory to prior chemotherapeutics and one dog naïve to chemotherapeutic treatment were enrolled. Vinorelbine (15 mg m(-2) IV) was administered intravenously along with concurrent oral anti-inflammatory drugs, if tolerated. A median of six doses of vinorelbine (range: 1-16) was administered. Two dogs (14%) had partial responses, and eight (57%) experienced stable disease. Subjective improvement in clinical signs was noted in 11 dogs (78%). Adverse events were mild and primarily haematological in nature. Median time to progression was 93 days (range: 20-239 days). Median survival time for all dogs was 187 days; median survival for 13 pre-treated dogs was 207 days. Vinorelbine may have utility in the management of canine primary urinary bladder carcinoma and should be evaluated in a prospective study. © 2013 John Wiley & Sons Ltd.

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

    Conclusion: Our data confirm the heterogeneity of CUP cases and variable treatment courses. This highlights the importance of establishing a national registry for this subgroup of cancer patients. Moreover, there is a need to develop multidisciplinary specialist teams and protocols to manage this group of patients, and participation in clinical trials should be strongly encouraged.

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

    Objective: To evaluate the value of 18 F-deoxyglucose (FDG) positron emission tomography (PET) in detecting the primary focus of metastatic cancer with an unknown primary. Methods: Twenty-nine patients with various histological types of metastases from an unknown primary after extensive conventional diagnostic work-up were studied. After intravenous 370 MBq FDG, whole body scan was made 50 minutes after injection. The results of FDG PET were compared with those of CT or MRI. Results: With FDG PET, the primary tumors were identified in 13 patients and confirmed by pathology. The corresponding detection rate was 44.8% (13/29) as compared with 27.6% (8/29) by CT or MRI. In addition, 26 metastases were discovered by FDG PET whole body imaging but only 13 were found by CT or MRI. During 2-13 months' follow-up, the mortality rates were 15.4%(2/13) and 42.9%(6/14) for patients with the primary tumor identified or unidentified. Conclusions: FDG PET is valuable in staging, selecting appropriate treatment protocol and predicting prognosis for patients suffering from metastatic cancers with an unknown primary

    The results are reported of a selected series of 41 patients with medullary carcinoma of the breast, treated with primary radiotherapy with (24 patients) or without (17 patients) adjuvant chemotherapy. Complete responses to radiotherapy occurred with moderate doses (67% of the patients had a complete response after a dose of 55-60 Gy) and were increased by the addition of an irradiation boost. The 6-year actuarial free of local recurrence survival, metastase-free survival and survival rates were 86, 83, and 83%, respectively. The 6-year actuarial probability of living with breast preserved was 72%. Recurrences and survivals were not influenced by the tumor size or clinical axillary node status. Adjuvant chemotherapy had no effect on the rate of recurrence or survival. 14 refs.; 3 tabs

  16. Research advances in cellular immunotherapy for primary hepatocellular carcinoma

    2014-09-01

    Full Text Available The present therapy for primary hepatocellular carcinoma (HCC consists of surgery as well as local radiotherapy and chemotherapy. However, the majority of patients are susceptible to recurrence after comprehensive treatment, and the overall treatment outcome is not ideal due to the lack of effective drugs and strategies. Increasing evidence has demonstrated that the immune system is closely related to the development, progression, metastasis, and recurrence of HCC. Thus, immune therapy, especially cellular immunotherapy, could regulate immune function and induce specific antitumor immunity to achieve the goal of controlling HCC and reducing its recurrence and metastasis, which has become an essential part in the comprehensive treatment of HCC. The findings in preclinical and clinical studies on cellular immunotherapy for HCC data are reviewed, and the current problems are discussed.

    2012-01-01

    Full Text Available Colorectal cancer (CRC is a heterogeneous disease, developing through a multipathway sequence of events guided by clonal selections. Pathways included in the development of CRC may be broadly categorized into (a genomic instability, including chromosomal instability (CIN, microsatellite instability (MSI, and CpG island methylator phenotype (CIMP, (b genomic mutations including suppression of tumour suppressor genes and activation of tumour oncogenes, (c microRNA, and (d epigenetic changes. As cancer becomes more advanced, invasion and metastases are facilitated through the epithelial-mesenchymal transition (EMT, with additional genetic alterations. Despite ongoing identification of genetic and epigenetic markers and the understanding of alternative pathways involved in the development and progression of this disease, CRC remains the second highest cause of malignancy-related mortality in Canada. The molecular events that underlie the tumorigenesis of primary and metastatic colorectal carcinoma are detailed in this manuscript.

    Full Text Available The thyroglossal duct cysts (TGDCs are the most common congenital anomaly of the thyroid, usually manifested as painless midline neck mass. Malignancy is very rare and is reported in around 1% of cases as an incidental finding after histopathological evaluation of resected cyst. Papillary carcinoma is the most common carcinoma reported in TGDC. Here, we report a case of 17-year-old-female, who presented with a gradually increasing midline neck mass which moves with swallowing. On imaging a diagnosis of infected TGDC was made. The Sistrunk operation was done and a diagnosis of primary papillary carcinoma arising in a TGDC was rendered histopathologically. The contemporary appearance of papillary carcinoma thyroid was reported in about 20% cases of TGDC carcinoma, thus it is essential to differentiate primary papillary carcinoma arising in a TGDC from those of metastatic papillary carcinoma thyroid by strict diagnostic criteria.

    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.

    Background and purpose: We investigated the results of using stereotactic radiotherapy (SRT) for 58 patients with renal cell carcinomas (RCC) who were evaluated restrospectively for response rates, local control rates and side effects. Patients and methods: From October 1997 to January 2003, 50 patients suffering from metastatic RCC and eight patients with inoperable primary RCC received high-dose fraction SRT while placed in a stereotactic body-frame. The most common dose/fractionation schedules used were 8 Gyx4, 10 Gyx4 and 15 Gyx3 during approximately 1 week. Results: SRT-treated tumor lesions regressed totally in 30% of the patients at 3-36 months, whereas 60% of the patients had a partial volume reduction or no change after a median follow-up of 37 months (SD 17.4) for censored and 13 months (SD 12.9) for uncensored patients. Side effects were generally mild. Of 162 treated tumors, only three recurred, yielding a local control rate of 90-98%, considering the 8% non-evaluable sites as defined here. For patients with one to three metastases, the time to new spread was 9 months. Conclusions: Our use of SRT for patients with primary and metastatic RCC yielded a high local control rate with low toxicity. Patients with one to three metastases, local recurrences after nephrectomy or inoperable primary tumors benefited the most, i.e. had fewer distant recurrences (13/23) and longer survival times compared to patients with >3 metastases (24/27 recurrences)

    Primary signet-ring carcinoma is a very aggressive and rare variant of a primary urinary bladder cancer, accounting for less than 1% of cases. We reported on a 76-year-old patient with primary signet-ring carcinoma who occurred metastatic lymphadenopathy with extranodal invasion causing intraluminal tumor thrombi in the adjacent vein, and pulmonary metastasis over the course of three months. We demonstrated the computed tomography findings of primary signet-ring carcinoma of the bladder and correlated the imaging findings with the pathologic features. We reviewed the distinguishing imaging findings of the primary signet-ring carcinoma compared with urothelial cell carcinoma, the most common subtype of the bladder cancer.

    Full Text Available Background and objective The aim of this study is to investigate the clinical characteristics of patients with primary bronchopulmonary carcinoma complicated with chronic obstructive pulmonary disease (COPD, and to optimize the early diagnoses in the coexistence of COPD and primary bronchopulmonary carcinoma. Methods The clinical data of 118 patients with COPD complicated with primary bronchopulmonary carcinoma were analyzed retrospectively, including age, sex, smoking history, smoking index, clinical symptoms and signs, pathological type, staging, metastasis site and lung function index. 120 patients with simple COPD were selected as control. Results The smoking rate (55.1% and smoking index ≥400 branch /year (90.8% of the patients with COPD complicated with primary bronchopulmonary carcinoma were higher than the simple COPD group (20.8%, 48.0%. The difference between the two groups was statistically significant (P0.05, while the incidence of hemoptysis, weight loss, chest pain, hoarseness, pleural effusion and atelectasis were significantly higher than those in simple COPD group (P0.05, but the diffusing capacity of carbon monoxide (DLCO of COPD patients complicated with primary bronchopulmonary carcinoma was lower than that of simple COPD patients (P<0.05 . In the COPD patients with primary bronchopulmonary carcinoma, squamous cell carcinoma was the most common pathological type (51.7%. Male patients were mainly squamous cell carcinoma (60.7%, while female patients with adenocarcinoma (69.0%. Conclusion COPD combined with primary bronchopulmonary carcinoma occurs in male smokers more. There is higher incidence of squamous cell carcinoma. When they are first diagnosed, most of them are advanced or located late, due to no specific clinical symptoms at the early stages. Periodic chest CT examination for COPD patients can help early diagnoses of primary bronchopulmonary carcinoma.

    Purpose/Objective: Nasopharyngeal carcinoma (NPC) is not a common malignancy of the head and neck in the United States and presents a great challenge to the radiation oncologists in this country. Its management is radiotherapeutic and technically demanding and calls for careful treatment techniques to include the primary and the lymphatic drainage areas to high doses while sparing the neighboring organs such as the spinal cord, eyes, temporal lobes and midrain. This refresher course will review the clinical course, pattern of spread with manifestations of various neurologic syndromes of the disease. The radiotherapeutic management of primary lesion will be discussed in detail including the treatment techniques, placement of the irradiation portals, dose levels, etc. Treatment results as reported in the literature as well as those achieved at the MGH will be presented. Special emphasis will be placed on the routine use of intracavitary implant to boost the primary site and its technical aspects. Relapsed NPC after previous radiation therapy presents a difficult problem in management, but can be re-irradiated with occasional success by observing careful technique and fractionated intracavitary brachytherapy and the local control rates will be briefly covered. Recurrent disease in the neck will be managed by neck dissection. Xerostomia is undesirable and common sequelae following radical radiation therapy for NPC. Efforts are being made to decrease its magnitude by using higher energies of photons, i.e. 10 MV to spare a portion of the parotid glands with some promising results. Because of the unique location of the primary lesion, currently a modified BID program (MBID) is used and its techniques and treatment concept are discussed

    Purpose: To retrospectively analyze results of external beam therapy (EBT) with brachytherapy (BT) for primary vaginal squamous cell carcinoma (PVSCC). Materials and methods: From 1970 to 2001, 91 patients were included. FIGO stages were: I (29%), II (38%), III (29%) and IVa (4%). EBT delivered a median total dose of 50 Gy to the pelvis. BT was performed with a customized intra-vaginal applicator and in 36% of applications combined endocavitary and interstitial BT. ICRU Report 38 parameters were reported. Results: The 5-year cause specific survival (CSS) rates were: 83% for stage I, 76% for stage II, 52% for stage III, and 2 of the 4 stage IVa patients died 9 and 36 months after treatment. The 5-year pelvis control rates were: 79% for stage I and II and 62% for stage III. Recurrences as a first event were local only in 68% of cases, nodal only in 10%, metastatic only in 13% and combined in 9%. In multivariate analysis: stage (I and II versus II and IV), response to EBT (evaluated at BT), and the number of BT applications were statistically significant for CSS. Grade 2-3 toxicities were as follows (Franco-Italian Glossary): rectum (n = 3), sigmoid colon and small bowel (n = 8), bladder (n = 5), ureter (n = 4) and vagina (n = 13). Anterior location of the tumor increased bladder toxicity (p = 0.01) and total reference air kerma was higher in patients who experienced grade 2-3 urinary or digestive toxicity (p = 0.03). Conclusion: EBT with BT is an effective treatment for patients with stage I-II PVSCC. The incidence and severity of late toxicity were relatively low. Recent advances in the treatment of cervix carcinoma emphasize the need for concomitant radio-chemotherapy in stages III-IV and the use of MRI for treatment planning

    Despite the clinical significance of liver metastases, the difference between molecular and cellular changes in primary colorectal cancers (CRC) and matched liver metastases is poorly understood. In order to compare gene expression patterns and identify fusion genes in these two types of tumors, we performed high-throughput transcriptome sequencing of five sets of quadruple-matched tissues (primary CRC, liver metastases, normal colon, and liver). The gene expression patterns in normal colon and liver were successfully distinguished from those in CRCs; however, RNA sequencing revealed that the gene expression between primary CRCs and their matched liver metastases is highly similar. We identified 1895 genes that were differentially expressed in the primary carcinoma and liver metastases, than that in the normal colon tissues. A major proportion of the transcripts, identified by gene expression profiling as significantly enriched in the primary carcinoma and metastases, belonged to gene ontology categories involved in the cell cycle, mitosis, and cell division. Furthermore, we identified gene fusion events in primary carcinoma and metastases, and the fusion transcripts were experimentally confirmed. Among these, a chimeric transcript resulting from the fusion of RNF43 and SUPT4H1 was found to occur frequently in primary colorectal carcinoma. In addition, knockdown of the expression of this RNF43-SUPT4H1 chimeric transcript was found to have a growth-inhibitory effect in colorectal cancer cells. The present study reports a high concordance of gene expression in the primary carcinoma and liver metastases, and reveals potential new targets, such as fusion genes, against primary and metastatic colorectal carcinoma.

    This bi-centric study aimed to determine the role of receptor PET/CT using {sup 68}Ga-DOTA-NOC in the detection of undiagnosed primary sites of neuroendocrine tumours (NETs) and to understand the molecular behaviour of the primarily undiagnosed tumours. Overall 59 patients (33 men and 26 women, age: 65 {+-} 9 years) with documented NET and unknown primary were enrolled. PET/CT was performed after injection of approximately 100 MBq (46-260 MBq) of {sup 68}Ga-DOTA-NOC. The maximum standardised uptake values (SUV{sub max}) were calculated and compared with SUV{sub max} in known pancreatic NET (pNET) and ileum/jejunum/duodenum (SI-NET). The results of PET/CT were also correlated with CT alone. In 35 of 59 patients (59%), {sup 68}Ga-DOTA-NOC PET/CT localised the site of the primary: ileum/jejunum (14), pancreas (16), rectum/colon (2), lungs (2) and paraganglioma (1). CT alone (on retrospective analyses) confirmed the findings in 12 of 59 patients (20%). The mean SUV{sub max} of identified previously unknown pNET and SI-NET were 18.6 {+-} 9.8 (range: 7.8-34.8) and 9.1 {+-} 6.0 (range: 4.2-27.8), respectively. SUV{sub max} in patients with previously known pNET and SI-NET were 26.1 {+-} 14.5 (range: 8.7-42.4) and 11.3 {+-} 3.7 (range: 5.6-17.9). The SUV{sub max} of the unknown pNET and SI-NET were significantly lower (p < 0.05) as compared to the ones with known primary tumour sites; 19% of the patients had high-grade and 81% low-grade NET. Based on {sup 68}Ga-DOTA-NOC receptor PET/CT, 6 of 59 patients were operated and the primary was removed (4 pancreatic, 1 ileal and 1 rectal tumour) resulting in a management change in approximately 10% of the patients. In the remaining 29 patients, because of the far advanced stage of the disease (due to distant metastases), the primary tumours were not operated. Additional histopathological sampling was available from one patient with bronchial carcinoid (through bronchoscopy). Our data indicate that {sup 68}Ga-DOTA-NOC PET/CT is

    Full Text Available Primary infiltrating ductal carcinoma of the axillary breast is rare and has a high frequency of lymph node (LN involvement. We report a woman with primary infiltrating ductal carcinoma arising from the right axillary breast with metastasis to the contralateral chest wall. Excisional biopsy of the left chest wall nodule and the right axillary mass was carried out and both showed invasive ductal carcinomas histologically. The lesion of the right axillary mass arose from the breast tissue, rather than the LN. Further surgery proved the right axillary LN metastasis. After further review, a primary infiltrating ductal carcinoma of the right axillary breast with metastasis to axillary LNs and contralateral chest wall was diagnosed. The patient also received chemotherapy and radiation and there was no evidence of tumor recurrence after treatment. The present report demonstrated a rare case with uncommon manifestation. Lesions of uncertain origin around the periphery of the breast should be suspected for breast carcinoma.

    We present here a case of a 42-year-old woman diagnosed with primary neuroendocrine carcinoma of the breast (NECB). We discuss the importance of histological criteria for primary neuroendocrine mammary carcinoma, established by WHO in 2003 and 2012. After an overview of different cases of primary neuroendocrine carcinoma of the breast published in the literature, we present information about differential diagnosis, prognostic factors, and surgical and adjuvant treatment. Prognosis of NECB is not different from that of other invasive breast carcinomas and the most important prognostic factor is tumor grade (G). There is no standard treatment and patients should be treated similarly to patients with invasive ductal carcinoma, NOS (not otherwise specified), whose choice of therapy depends on tumor's size, degree of differentiation, clinical stage, and hormonal status.

    Objective: To investigate the expression and clinical significance of KIAA1199 in primary hepatocellular carcinoma. Methods: A total of 136 cases of primary hepatocellular carcinoma tissues and paired adjacent tissues were collected. Immunohistochemistry and Western blot were used to detect the expression of KIAA1199 in primary hepatocellular carcinoma tissues and paired adjacent tissues. The relationship between KIAA1199 and clinicopathological parameter of primary hepatocellular carcinoma was analyzed. Results: The positive rate of KIAA1199 in primary hepatocellular carcinoma was 82.3% (112/136), which was higher than that in paired para-cancerous tissues (14.7%, 20/136). High expression of KIAA1199 was significantly correlated with age, cirrhosis history, tumor size, tumor number, degree of differentiation, TNM staging and microvenous invasion (MVI) ( P 0.05). The Kaplan-Meier survival curves indicated that high KIAA1199 expression was associated with poor survival ( P hepatocellular carcinoma, which is significantly correlated with the clinicopathological features and prognosis, high expression of KIAA1199 increased the risk of death in patients with primary hepatocellular carcinoma.

    Full Text Available Although pulmonary small cell carcinoma (SCC is seen frequently, SCC that originates from the extrapulmonary organs is extremely rare. We herein report a case of a SCC located in the lesser omentum. A 61-year-old male was admitted to our department due to intermittent epigastralgia for 2 months. Ultrasonography (US revealed an irregular hypoechoic mass measuring about 58 mm × 50 mm × 45 mm under the left lobe of the liver. Magnetic resonance imaging (MRI was performed to verify the irregular mass with T1- and T2- weighted images between the left lobe of liver and the stomach. At laparotomy, the well-circumscribed neoplasm was found in the lesser omentum, and the fundus of the neoplasm was located in the root of left gastric artery. Intraoperative microscopic evaluation of frozen sections revealed malignancy of the lesser omentum. Resection of the neoplasm was performed, and the combined resection of the vagal nerve was also performed for the partial adhesion. Pyloroplasty was performed for avoiding delayed gastric emptying caused by combined resection of vagal nerve. The lymph nodes dissection at lesser curvature and right cardia was also performed with a negative result. Based on the histological findings, the final diagnosis of primary lesser omental SCC was confirmed. The pathologic staging showed locoregional disease.

The tumor is located on the lesser curvature of the stomach under the appearance of a crateriform formation, 3.5 cms. in diameter, fast adhering to the pancreas. The esophagus and cardia are not affected by this process. Metastases were found in the heart, liver, capsule of the pancreas, lungs and adrenal glands. The histological examination reveals in te primary tumor and in the metastatic foci a carcinoma of epidermoid type. The AA. are inclined to believe that the tumor might have arisen through an epidermoid-metaplastic process of the gastric mucosa.

    A diagnosis of primary peritoneal serous carcinoma (PPSC) requires exclusion of a source in other reproductive organs. Serous tubal intraepithelial carcinoma (STIC; stage 0) has been described in asymptomatic women with BRCA mutations and linked to a serous cancer precursor in the fimbria. This study examined the frequency of STIC in PPSC and its clinical outcome in BRCA-positive women. Presence or absence of STIC was recorded in consecutive cases meeting the 2001 WHO criteria for PPSC, including 26 patients with nonuniform sampling of the fallopian tubes (group 1) and 19 patients with complete tubal examination (group 2; sectioning and extensively examining the fimbriated end, or SEE-FIM protocol). In selected cases, STIC or its putative precursor and the peritoneal tumor were analyzed for p53 mutations (exons 1 to 11). Outcome of STIC was ascertained by literature review. Thirteen (50%) of 26 PPSCs in group 1 involved the endosalpinx, with nine STICs (35%). Fifteen (79%) of 19 cases in group 2 contained endosalpingeal involvement, with nine STICs (47%). STIC was typically fimbrial and unifocal, with variable invasion of the tubal wall. In five of five cases, the peritoneal and tubal lesion shared an identical p53 mutation. Of 10 reported STICs in BRCA-positive women, all patients were without disease on follow-up. The fimbria is the source of nearly one half of PPSCs, suggesting serous malignancy originates in the tubal mucosa but grows preferentially at a remote peritoneal site. The generally low risk of recurrence in stage 0 (STIC) disease further underscores STIC as a possible target for early serous cancer detection and prevention.

    Aberrant expression of E-cadherin has been associated with the development of metastases in patients with breast cancer. Even though the expression of E-cadherin has been studied in primary breast tumors, little is known about its expression at the distant metastatic sites. We investigate the relationship between E-cadherin expression in primary breast carcinoma and their distant, non-nodal metastases. Immunohistochemical analysis of E-cadherin was performed in tissues from 30 patients with primary invasive breast carcinoma and their distant metastases. E-cadherin expression was evaluated as normal or aberrant (decreased when compared with normal internal positive controls, or absent). Twenty-two (73%) invasive carcinomas were ductal, and eight (27%) were lobular. Of the primary invasive ductal carcinomas, 55% (12/22) had normal E-cadherin expression and 45% (10/22) had aberrant expression. All of the metastases expressed E-cadherin with the same intensity as (12 tumors) or with stronger intensity than (10 tumors) the corresponding primaries. Of the invasive lobular carcinomas, one of eight (12%) primary carcinomas and none of the metastases expressed E-cadherin in the cell membranes, but they accumulated the protein in the cytoplasm. Aberrant E-cadherin expression is frequent in invasive ductal carcinomas that progress to develop distant metastases. Distant metastases consistently express E-cadherin, often more strongly than the primary tumor. Invasive lobular carcinomas have a different pattern of E-cadherin expression, suggesting a different role for E-cadherin in this form of breast carcinoma

    Reports on the outcome of curative radiotherapy for the primary hepatocellular carcinoma (HCC) are rarely encountered in the literature. In this study, we report our experience of a clinical trial where fractionated stereotactic radiotherapy (SRT) was used in treating a primary HCC. A retrospective analysis was performed on 20 patients who had been histologically diagnosed as HCC and treated by fractionated SRT. The long diameter of tumor measured by CT was 2 ∼ 6.5 cm (average: 3.8 cm). A single dose of radiation used in fractionated SRT was 5 or 10 Gy; each dose was prescribed based on the planning target volume and normalized to 85 ∼ 99% isocenter dose. Patients were treated 3 ∼ 5 times per week for 2 weeks, with each receiving a total dose of 50 Gy (the median dose: 50 Gy). The follow up period was 3 ∼ 55 months (the median follow up period: 23 months). The response rate was 60% (12 patients), with 4 patients showing complete response (20%), 8 patients showing partial response (40%), and 8 patients showing stable disease (40%). The 1-year and 2-year survival rates were 70.0% and 43.1%, respectively,and the median survival time was 20 months. The 1-year and 2-year disease free survival rates were 65% and 32.5%, respectively, and the median disease-free survival rate was 19 months. Some acute complications of the treatment were noted as follows: dyspepsia in 12 patients (60%), nausea/emesis in 8 patients (40%), and transient liver function impairment in 6 patients (30%). However, there was no treatment related death. The study indicates that fractionated SRT is a relatively safe and effective method for treating primary HCC. Thus, fractionated SRT may be suggested as a local treatment for HCC of small lesion and containing a single lesion, when the patients are inoperable or operation is refused by the patients. We thought that fractionated SRT is a challenging treatment modality for the HCC

    Full Text Available BACKGROUND: A direct comparison of prognosis between patients with regional lymph node metastases (LNM detected synchronously with the primary melanoma (primary LNM, patients who developed their first LNM subsequently (secondary LNM and those with initial LNM in melanoma with unknown primary site (MUP is missing thus far. PATIENTS AND METHODS: Survival of 498 patients was calculated from the time point of the first macroscopic LNM using Kaplan Meier and multivariate Cox hazard regression analysis. RESULTS: Patients with secondary LNM (HR = 0.67; p = 0.009 and those with initial LNM in MUP (HR = 0.45; p = 0.008 had a better prognosis compared to patients with primary LNM (median survival time 52 and 65 vs. 24 months, respectively. A high number of involved nodes, the presence of in-transit/satellite metastases and male gender had an additional independent unfavourable effect. CONCLUSIONS: Survival of patients with LNM in MUP and with secondary LNM is similar and considerably more favourable compared to those with primary LNM. This difference needs to be considered during patient counselling and for stratification purposes in clinical trials. The assumption of an immune privilege of patients with MUP which is responsible for rejection of the primary melanoma, and results in a favourable prognosis is not supported by our data.

    Purpose: The management of patients with cervical lymph-node metastases from unknown primary site (UPS) remains a matter of discussion. This study aimed to analyze the results and prognostic factors in a series of patients treated with radiotherapy. Methods and Materials: Data from 113 patients who presented with cervical lymph nodes metastases from UPS treated from 1980 to 2004 were reviewed. Eighty-seven patients (77.0%) were squamous cell carcinoma (SCC). Ninety-one patients were treated with curative and 22 with palliative intent. Fifty-nine of 113 patients (52.2%) received surgery followed by radiotherapy and 54 of 113 (47.8%) received radiotherapy alone. Radiotherapy was delivered to the neck and pharyngeal mucosa in 67 patients and to the ipsilateral or bilateral neck in 45 patients. Twenty-one patients (18.5%) also received chemotherapy. Results: The 5-year overall survival rates were 40.7% for the entire group and 46.6% for the SCC subgroup. The occurrence of the occult primary was observed in 23 of 113 patients (20.3%), 19 (82.6%) within the head and neck region. At multivariate analysis, treatment with curative intent and extensive irradiation of bilateral neck and pharyngeal mucosa were favorable prognostic factors for the whole series, and treatment with curative intent, extensive irradiation of bilateral neck and pharyngeal mucosa, and absence of extracapsular spread were favorable prognostic factors for the SCC subgroup. Conclusions: Patients with cervical lymph node metastases from UPS have a similar prognosis to those affected by other head and neck malignancies. Curative treatment strategies including neck dissection and extensive irradiation by three-dimensional conformal radiation therapy resulted in significantly better outcomes

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

    Full Text Available The molecular and cellular mechanisms which drive metastatic spread are the topic of constant debate and scientific research due to the potential implications for cancer patients' prognosis. In addition to genetics and environmental factors, mechanics of single cells and physical interaction with the surrounding environment play relevant role in defining invasive phenotype. Reconstructing the physical properties of metastatic clones may help to clarify still open issues in disease progression as well as to lead to new diagnostic and therapeutic approaches. In this perspective cancer of unknown primary origin (CUP identify the ideal model to study physical interactions and forces involved in the metastatic process. We have previously demonstrated that MET oncogene is mutated with unexpected high frequency in CUPs. We here analyze and discuss how the MET activation by somatic mutation may affect physical properties in giving rise to such a highly malignant syndrome, as that defined by CUP.

    Full Text Available Squamous cell ovarian and sigmoid colon carcinomas are extremely rare malignancies. Because of their rarity, it is difficult to investigate the clinical characteristics and prognosis of patients with theses malignancies, and therefore, the increased interest in each clinical case report is highly relevant. Multiple primary squamous cell ovarian and sigmoid colon carcinomas are the subject of discussion and differential diagnosis of sigmoid colon cancer with secondary ovarian cancer. Histopathological and clinical characteristics of the tumors were present and evidences in favor of the multiple primary malignancies were given. The association of squamous cell ovarian and sigmoid colon carcinomas with human papilloma virus type 16 was shown.

    To evaluate the surgical diagnosis and treatment of primary hyperthyroidism complicated with occult thyroid carcinoma. Data of 51 cases of primary hyperthyroidism complicated with occult thyroid carcinoma admitted during January 2004 to November 2014 were analyzed retrospectively. The incidence of occult thyroid carcinoma was 5.03% in hyperthyroidism,and 47 cases (92.16%) were female. The preoperative diagnosis of all these 51 cases was primary hyperthyroidism and 11 cases were diagnosed thyroid carcinoma at the same time;25 cases were diagnosed thyroid carcinoma by frozen section and the remaining 26 cases were diagnosed by postoperative pathology. Finally,26 cases underwent subtotal thyroidectomy,4 cases underwent total thyroidectomy, and 21 cases underwent total thyroidectomy with lymphadenectomy. The tumor size ranged from 0.1 to 1.0 cm [mean:(0.63 ± 0.35) cm]. The lesions were less than or equal to 0.5 cm in 28 cases (54.9%). The follow-up lasted from 1 to 121 months [mean:(28.6 ± 22.7)months] in 43 patients,and all of them survived. Primary hyperthyroidism complicated with occult thyroid carcinoma is commonly found in female patients. Preoperative diagnosis is difficult. Ultrasound is the major examining method. Frozen section can increase the detection rate. The postoperative prognosis of hyperthyroidism complicated with occult thyroid carcinoma is satisfactory.

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

    Primary neuroendocrine carcinoma of the breast is a very rare malignant tumor. There are not many cases reported in the English literature since it was first documented in 1983. Reports on the imaging features, in particular the ultrasonographic features of this rare tumor are scarce. Herein, we report a case of aggressive primary infiltrating neuroendocrine carcinoma of the breast, masquerading as an inflammatory breast condition in a 22-year-old young lady, perhaps the youngest case ever reported in the English literature. We discuss the imaging features and highlight the Doppler ultrasonographic findings of this rare breast carcinoma. This is the first documentation on Doppler ultrasonographic findings of primary neuroendocrine carcinoma of the breast in the literature

    To evaluate the prognostic value of maximum primary tumor diameter (MPTD) in nasopharyngeal carcinoma (NPC). Three hundred and thirty-three consecutive, newly-diagnosed NPC patients were retrospectively reviewed. Kaplan-Meier analysis and the log-rank test were used to estimate overall survival (OS), failure-free survival (FFS), distant metastasis-free survival (DMFS) and local relapse-free survival (LRFS). Cox proportional hazards regression analysis was used to assess the prognostic value of MPTD. Median follow-up was 66 months (range, 2–82 months). Median MPTD in stage T1, T2, T3 and T4 was 27.9, 37.5, 45.0 and 61.3 mm, respectively. The proportion of T1 patients with a MPTD ≤ 30 mm was 62.3%; 72% and 62.9% of T2 and T3 patients had a MPTD > 30–50 mm, and 83.5% of T4 patients had a MPTD > 50 mm. For patients with a MPTD ≤ 30 mm, > 30–50 mm and > 50 mm, the 5-year OS, FFS, DMFS and LRFS rates were 85.2%, 74.2% and 56.3% (P < 0.001); 87%, 80.7% and 62.8% (P < 0.001); 88.7%, 86.4% and 72.5% (P = 0.003); and 98.2%, 93.2% and 86.3% (P = 0.012), respectively. In multivariate analysis, MPTD was a prognostic factor for OS, FFS and DMFS, and the only independent prognostic factor for LRFS. For T3-T4 patients with a MPTD ≤ 50 mm and > 50 mm, the 5-year OS, FFS and DMFS rates were 70.4% vs. 58.4% (P = 0.010), 77.5% vs. 65.2% (P = 0.013) and 83.6% vs. 73.6% (P = 0.047), respectively. In patients with a MPTD ≤ 30 mm, 5-year LRFS in T1, T2, T3 and T4 was 100%, 100%, 88.9% and 100% (P = 0.172). Our data suggest that MPTD is an independent prognostic factor in NPC, and incorporation of MPTD might lead to a further refinement of T staging

    Full Text Available primary treatment for unresectable hepatocellular carcinoma (HCC. In this unit, 185 patients with a new diagnosis of HCC not amenable to surgery were seen between 1988 and 1991. Intended therapy for these patients was chemoembolisation with doxorubicin (60 mg/m2 and lipiodol, repeated at six week intervals until it was technically no longer possible o.r until complete tumour response had been obtained. Chemoembolisation was possible in 67 of the 185 (37%. Reasons for exclusion were portal vein occlusion (n=36, decompensated cirrhosis (n 44, distant metastases (n=5, diffuse tumour or unsuitable anatomy (tumour or vasculature (n=11, patient refusal (n=11, and other (n=11. Patients excluded from treatment survived for a median of 10 weeks (range 3 days-19 months. In patients treated, 18 had small HCC (4cm and 49 had large or multifocal HCC. Chemoembolisation was carried out a median of two sessions for small and three sessions for large tumours. Ten of 18 patients with small HCC showed a 50% or greater reduction in tumour size. Five of 49 patients with large or multifocal tumours showed a response to treatment. Median overall survival for treated patients was 36 weeks (range 3 days–4 years. One patient has subsequently undergone liver transplantation with no recurrence and minimal residual disease at transplantation. Two other patients are alive three years after chemoembolisation, one with no evidence of recurrent disease. No patient was thought suitable for surgery after their response to chemoembolisation. Chemotherapy related complications were seen in 22%. Complications were significantly more common in patients with larger tumours and poor liver reserve. Five patients died as a result of chemotherapy related complications. In conclusion, only one third of UK patients with unresectable HCC are treatable by chemoembolisation. Results with small tumours are encouraging, with a high response rate and the possibility of surgical intervention in

    Patients with cancer of unknown primary (CUP) in the head neck region are generally treated with neck dissection followed by radiotherapy at times combined with chemotherapy, a treatment associated with considerable side effects. Some of these tumors may originate as human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OSCC), with better clinical outcome than head neck squamous cell cancer (HNSCC) in general, and could potentially do well with less treatment. Here, we therefore investigated whether HPV status and p53-expression correlated to clinical outcome in patients with CUP in the head neck region. Fifty metastases were analyzed for presence of HPV DNA, and expression of p16 INK4A and p53 and the data were correlated to clinical outcome. Patients with HPV DNA-positive (HPV DNA+ ) metastases had significantly better 5-year overall survival (OS) compared to those with HPV DNA− metastases (80.0% vs. 36.7%, respectively; P = 0.004), with a similar tendency for disease-free survival (DFS). These survival rates showed excellent concordance with those of HPV DNA+ and HPV DNA− OSCC in Sweden during the same time period, strengthening the hypothesis that HPV DNA+ head and neck CUP may originate from HPV DNA+ OSCC. In addition, having absent/intermediary-low as compared to high expression of p53 correlated to a better prognosis with a 69% as compared to 14% 5-year OS, respectively (P < 0.001), and for DFS the tendency was analogous. In conclusion, both HPV status and p53 expression are valuable prognostic factors in patients with CUP in the head and neck region and should be further explored for clinical use

    Primary small cell carcinoma of the esophagus (SCCE) is a highly aggressive disease characterized by early dissemination and poor prognosis. Because of the rarity of this disease, few previous studies have investigated the biomarkers associated with its prognosis. Leucine-rich repeat-containing G-protein coupled receptor 5 (Lgr5) is a stem cell marker and a member of the canonical Wnt-signaling cascade. However, the clinical role of Lgr5 in SCCE remains unknown. Tissue sections were obtained from 44 patients diagnosed with SCCE and expression of Lgr5 was examined by immunohistochemistry. The correlations between Lgr5 expression, and clinical parameters and prognostic significance were evaluated. Lgr5 was expressed in SCCE cancer tissues. High Lgr5 expression was significantly correlated with lymph node metastasis (p = 0.003), late stage (p = 0.003) and unfavorable response to chemotherapy (p = 0.013) according to RECIST 1.0 criteria. Patients with higher Lgr5 expression levels had shorter overall survival times than those with lower expression levels. These results demonstrated that overexpression of Lgr5 was significantly correlated with lymph node metastasis, tumor stage, and response to chemotherapy. Furthermore, high levels of Lgr5 expression appeared to be associated with poorer survival in patients with SCCE

    Background and Purpose: In a retrospective study the role of radiation therapy for the treatment of primary tracheal carcinoma was investigated. Patients and Methods: Between 1984 and 1997, 25 patients with primary tracheal carcinoma were treated with external beam radiotherapy (17 squamous-cell carcinoma [SCC], 8 adenoid cystic carcinoma [ACC], median dose SCC 60 Gy, ACC 55 Gy). An additional brachytherapy boost was carried out in 10/25 patients (median dose SCC 18 Gy, ACC 15 Gy). Ten patients underwent operative treatment. Results: The median survival (Kaplan-Meier) for patients with SCC was 33 months (ACC 94.2). The 1-, 2- and 5-year survival rates (Kaplan-Meier) for patients with SCC were 64.7% (ACC 85.7%), 64.7% (ACC 85.7%), and 26% (ACC 85.7%). Patients with ACC and patients with a complete remission after treatment had a significantly better survival probability (log rank test, p [de

    Conclusion: PFTC is infrequently diagnosed preoperatively or intraoperatively due to its rarity, and has a varied and nonspecific presentation. Only 6.3% of the patients had typical symptoms suggestive of tubal carcinoma. This report may benefit surgeons by providing additional information about the clinicopathologic behavior of PFTC so that patients can be appropriately counseled.

    Background and purpose: Surgical excision remains the standard and most reliable curative treatment for eyelid carcinoma, but frequently causes functional and cosmetic impairment of the eyelid. We therefore investigated the efficacy and safety of radiation therapy in eyelid carcinoma. Patients and methods: Twenty-three patients with primary carcinoma of the eyelid underwent radiation therapy. Sebaceous carcinoma was histologically confirmed in 16 patients, squamous cell carcinoma in 6, and basal cell carcinoma in 1. A total dose of 50-66.6 Gy (median, 60 Gy) was delivered to tumor sites in 18-37 fractions (median, 30 fractions). Results: All but 3 of the 23 patients had survived at a median follow-up period of 49 months. The overall survival and local progression-free rates were 87% and 93% at 2 years, and 80% and 93% at 5 years, respectively. Although radiation-induced cataracts developed in 3 patients, visual acuity in the other patients was relatively well preserved. There were no other therapy-related toxicities of grade 3 or greater. Conclusion: Radiation therapy is safe and effective for patients with primary carcinoma of the eyelid. It appears to contribute to prolonged survival as a result of good tumor control, and it also facilitates functional and cosmetic preservation of the eyelid. (orig.)

    Neuroendocrine tumors are derived from cells that have the unique ability to synthesize, store and secrete a variety of metabolically active substances, peptides and amines, characteristic of the tissue of origin, which can cause distinct clinical syndromes. We present the case of a 58-year-old patient diagnosed and surgically treated in January 1996 for stage III inferior rectal cancer, who was readmitted after 18 years presenting persistent diarrheic syndrome and asthenia. Investigations performed (abdominal CT) showed multiple liver metastases, initially suspected as being related to the rectal cancer. Biopsy of liver metastases and pathological and immunohistochemical analysis demonstrated the neuroendocrine origin (moderately differentiated neuroendocrine tumor). Seven months after the identification of liver metastases and after initiation of oncological therapy with Interferon and Somatostatin, the patient presented severe hypoglycemia (serum glucose 13-70 mg/dl) proved to be due to insulin-like factors (serum insulin level 64.9 ìU/ml) secreted by metastases. Due to the aggressive evolution of neuroendocrine tumor, with multiple episodes of severe hypoglycemia, resistant to treatment, the patient died approximately one month after the occurrence of hypoglycemic episodes. Despite comprehensive tests (abdominal CT scan, colonoscopy, bone scintigraphy and PET/CT), the primary site of the neuroendocrine tumors remained unknown.

    Background: The results of treatment at the Free University Hospital of 44 patients with cervical lymph node metastasis of an unknown primary tumor were reviewed in order to establish an optimal treatment policy and to look for prognostic parameters. These results were compared with results of other treatment policies known from the literature. Patients and Method: Thirty-three out of the 44 patients received a treatment with curative intent; 22 cases received a unilateral neck dissection and postoperative radiotherapy, 7 were irradiated after an excisional biopsy and 4 received radical radiotherapy alone. Results: For the whole group 5- and 10-year overall survival was 50% and 44%, respectively, and for the group treated with curative intent 68% and 56%, respectively. Disease-free survival at 5 and 10 years after treatment for the whole group was 48% and 32%, respectively, and for the group treated with curative intent 63% and 37%, respectively. Conclusions: Multivariate analysis showed only treatment with intent and histology as significant independent prognostic factors for the whole group. For the patients treated with curative intent no significant influences of variables were found. (orig.) [de

    Thymic carcinoma is a rare, highly aggressive type of tumor that typically occurs in the anterior mediastinum. We describe the case of a 73-year-old man who presented with weakness, cough, dyspnea, anorexia, and weight loss. An echocardiogram showed an intrapericardial mass that occupied the space around the lateral walls of the left ventricle and distally compressed the right ventricle. Magnetic resonance imaging and a biopsy confirmed the presence of intrapericardial primary thymic carcinoma. The patient underwent surgical excision of the tumor and died of right ventricular rupture during the procedure. This case highlights the importance of considering thymic carcinoma whenever an otherwise unexplained intrapericardial mass is encountered.

    Primary gastric carcinoma is the most common cause of linitis plastica. Less frequently, metastatic gastric cancer from the breast, omental metastases and non-Hodgkin lymphoma involving the stomach have been reported to show similar radiographic findings as for linitis plastica. A metastatic gastric cancer from bladder cancer is extremely rare. We present an unusual case, the first to our knowledge, of gastric linitis plastica that resulted from a metastatic urothelial carcinoma of the bladder

    Signet ring cell carcinoma, a subtype of adenocarcinoma, is a rare cause of primary lung cancer. The authors report a case of primary lung signet ring cell carcinoma presenting as a cavitary Pancoast tumor in a 32-year-old male smoker. Beyond the rarity of primary lung signet ring cell carcinoma itself, the youth of the patient, his smoking status, the presence of cavitation, and the location of the tumor in the superior sulcus make it especially atypical.

    Purpose: The present study presents the experience at the University of Florida with treatment of patients with squamous cell carcinomas (SCC) metastatic to cervical lymph nodes from an unknown head-and-neck mucosal (H and NM) site with radiotherapy (RT) alone or in combination with neck dissection (ND). Methods and Materials: The study included 126 patients treated with curative intent from 1964 to 1997. All patients had follow-up for at least 2 years. No patients were lost to follow-up. Results: Twelve patients (10%) developed SCC in H and NM sites at 0.5 to 10.9 years (median, 1.8 years). The rate of developing carcinomas in H and NM sites at 5 years was 13%. Histologic differentiation significantly affected the rate of developing carcinomas in H and NM sites in multivariate analysis. Sixteen patients (13%) had persistent nodal disease and 12 patients (10%) developed recurrent nodal disease at 0.5 to 10.9 years (median, 1.1 years). The nodal control rate at 5 years was 78%. Nodal size, N stage, and planned ND significantly affected the rate of nodal control in multivariate analysis. Nineteen patients (15%) developed distant metastasis at 0.2-5.1 years (median, 0.9 years). The distant metastases rate at 5 years was 14%. Extracapsular extension and RT dose significantly affected the risk of distant metastases in multivariate analysis. The overall absolute survival rate at 5 years was 47%. Extracapsular extension, N stage, RT dose for H and NM sites, and planned ND significantly affected absolute survival in multivariate analysis. The rate of cause-specific survival at 5 years was 67%. Extracapsular extension, nodal size, N stage, overall treatment time, and planned ND significantly affected cause-specific survival in multivariate analysis. Eight patients (6%) had severe postoperative complications and 6 patients (5%) had severe late complications. Conclusion: The present study supports the effectiveness of RT in lowering the rate of developing carcinomas in the H

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

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

    Molecular heterogeneity within primary breast carcinomas and among axillary lymph node (LN) metastases may impact diagnosis and confound treatment. In this study, we used short tandem repeated sequences to assess genomic heterogeneity and to determine hereditary relationships among primary tumor areas and regional metastases from 30 breast cancer patients. We found that primary carcinomas were genetically heterogeneous and sampling multiple areas was necessary to adequately assess genomic variability. LN metastases appeared to originate at different time periods during disease progression from different sites of the primary tumor and the extent of genomic divergence among regional metastases was associated with a less favorable patient outcome (P = 0.009). In conclusion, metastasis is a complex process influenced by primary tumor heterogeneity and variability in the timing of dissemination. Genomic variation in primary breast tumors and regional metastases may negatively impact clinical diagnostics and contribute to therapeutic resistance. PMID:26279627

    This investigation was undertaken to evaluate the relationship between Ga-67 uptake and radiotherapeutic response of primary lung cancer (squamous cell carcinoma), Ga-67 uptake of tumor was estimated on 16 patients with untreated primary lung cancer (squamous cell carcinoma). Ga-67 uptake was then compared with the response to radiation therapy (tumor reduction ratio). There was statistically significant inverse correlation between Ga-67 uptake and response to radiation therapy (r=-0.701, p<0.01). The fewer the Ga-67 accumulation in the tumor, the more effective radiotherapy in reducing tumor size. In conclusion, Ga-67 scintigraphy appears to be able to predict the response of primary lung cancer (squamous cell carcinoma) to radiation therapy. (author)

    We aimed to investigate the cost-effectiveness of a 2000-gene-expression profiling (GEP) test to help identify the primary tumor site when clinicopathological diagnostic evaluation was inconclusive in patients with cancer of unknown primary (CUP). We built a decision-analytic-model to project the lifetime clinical and economic consequences of different clinical management strategies for CUP. The model was parameterized using follow-up data from the Manitoba Cancer Registry, cost data from Manitoba Health administrative databases and secondary sources. The 2000-GEP-based strategy compared to current clinical practice resulted in an incremental cost-effectiveness ratio (ICER) of $44,151 per quality-adjusted life years (QALY) gained. The total annual-budget impact was $36.2 million per year. A value-of-information analysis revealed that the expected value of perfect information about the test's clinical impact was $4.2 million per year. The 2000-GEP test should be considered for adoption in CUP. Field evaluations of the test are associated with a large societal benefit.

    Mesenchymal origin of ureter tumors account for less than 3 percent of all primary ureteral tumors. Among mesenchymal tumors, primary leiomyoma of ureter is extremely rare. Here, we present a case of primary leiomyoma of ureter coexisting with renal cell carcinoma. When encountering well-defined homogeneously enhanced mass of ureter on computed tomography, radiologist should keep in mind that ureteral leiomyoma should be considered as differential diagnosis.

    Purpose: Patients with cancer of unknown primary (CUP) account for about 10% of patients with metastatic spinal cord compression (MSCC). This study aims to define the appropriate radiation regimen for these patients. Methods and Materials: Data of 143 CUP patients irradiated for MSCC were retrospectively evaluated. Short-course radiotherapy (RT) (1x8 Gy, 5x4 Gy, n = 68) and long-course RT (10x3 Gy, 15x2.5 Gy, 20x2 Gy, n = 75) plus 8 further potential prognostic factors (age, gender, performance status, visceral metastases, other bone metastases, number of involved vertebrae, ambulatory status, time of developing motor deficits before RT) were compared for functional outcome and survival. Results: Improvement of motor function occurred in 10% of patients, no further progression of motor deficits in 57%, and deterioration in 33%. On multivariate analysis, functional outcome was positively associated with slower development of motor deficits (p < 0.001), absence of visceral metastases (p = 0.008) and other bone metastases (p = 0.027), and ambulatory status (p = 0.054), not with the radiation regimen (p = 0.74). Recurrence of MSCC in the irradiated region occurred in 7 patients after median 6 months. Median survival was 4 months. On multivariate analysis, better survival was significantly associated with absence of visceral metastases (p < 0.001), absence of other bone metastases (p = 0.005), ambulatory status (p = 0.001), and slower development of motor deficits (p = 0.030). Conclusions: For MSCC treatment in patients with CUP, no significant difference was observed between short-course and long-course RT regarding functional outcome and survival. Short-course RT appears preferable, at least for patients with a poor predicted survival, as it is more patient convenient and more cost-effective

    {sup 99m}Tc-Sulfur Colloid is concentrated in Kupffer cells of the liver, whereas the new biliary agents such as {sup 99m}Tc-HIDA are processed by hepatic parenchymal cells. The distant metastatic lesions in skull and lung of the primary hepatocellular carcinoma in 38-year old Korean male were detected with {sup 99m}Tc-HIDA scintigraphy. The chest PA, skull bone X-ray and radionuclide scintigraphic studies are illustrated. This observation suggests that {sup 99m}Tc-HIDA scintigraphy is useful for detection of distant metastases of primary hepatocellular carcinoma.

    Primary vaginal carcinoma is a rare malignancy. There is little information regarding the optimal treatment. Management has primarily been with external-beam radiation therapy and brachytherapy. This paper examines the importance of brachytherapy and the significance of its techniques in the treatment of this disease. Brachytherapy plays an important part in the management of primary vaginal carcinoma. External-beam radiation therapy alone is not an adequate treatment for this disease. For stages II and III disease, there is a trend toward improved disease-free survival with the use of a temporary interstitial implant compared to an intracavitary application

    Full Text Available Primary signet ring cell carcinoma of the appendix is a very rare neoplasm that usually presents with signs and symptoms of acute appendicitis and in particular with a right lower abdominal pain. Preoperative imaging detection of appendiceal adenocarcinoma has an important value because it may result in an appropriate surgical procedure. We report a rare case of primary signet ring cell carcinoma of the vermiform appendix in an 80-year-old man who was misdiagnosed on computed tomography (CT scan as acute appendicitis.

    Liver cirrhosis and primary carcinoma of the liver were investigated in 1699 autopsies of atomic bomb survivors carried out in Hiroshima from 1956 to 1980. Liver cirrhosis, hepatocellular carcinoma and intrahepatic biliary carcinoma were observed in 116, 111, and 17 cases respectively, the ratios of man to woman and were 2.3, 3.9, and 1.8 with a mean age of 56, 60, and 67 years respectively. There was no evidence that exposure to a-bomb increased the risk of these diseases significantly. About 90% of the hepatocellular carcinomas was combined with liver cirrhosis. Weight of liver and spleen, amount of ascites, hemorrhage from the digestive canals, esophageal varix, combination with other diseases, and histologic correlation with the activities of HBs antigen and ..cap alpha..-fetoprotein were discussed with the relation to the exposure.

    Laryngeal tuberculosis is a rare disease. It is almost always associated with pulmonary tuberculosis. It occurs generally in adults without BCG vaccination or in cases of the acquired immune deficiency syndrome. On laryngoscopy and imaging, it often simulates laryngeal carcinoma, and confirmation is always histological. We report the case of a 36-year-old man who presented to our hospital with dysphonia and dysphagia. Laryngoscopy revealed a lesion of the left vocal cord and the ventricular strip. CT scan found focal, regular thickening of the left vocal cord, associated with irregular thickening of the posterior laryngeal wall. A biopsy confirmed the diagnosis of tuberculosis

    Full Text Available The detection of breast carcinoma cells in effusions is associated with rapidly fatal outcome, but these cells are poorly characterized at the molecular level. This study compared the gene array signatures of breast carcinoma cells in primary carcinomas and effusions. The genetic signature of 10 primary tumors and 10 effusions was analyzed using the Array-Ready Oligo set for the Human Genome platform. Results for selected genes were validated using PCR, Western blotting, and immunohistochemistry. Array analysis identified 255 significantly downregulated and 96 upregulated genes in the effusion samples. The majority of differentially expressed genes were part of pathways involved in focal adhesion, extracellular matrix-cell interaction, and the regulation of the actin cytoskeleton. Genes that were upregulated in effusions included KRT8, BCAR1, CLDN4, VIL2, while DCN, CLDN19, ITGA7, and ITGA5 were downregulated at this anatomic site. PCR, Western blotting, and immunohistochemistry confirmed the array findings for BCAR1, CLDN4, VIL2, and DCN. Our data show that breast carcinoma cells in primary carcinomas and effusions have different gene expression signatures, and differentially express a large number of molecules related to adhesion, motility, and metastasis. These differences may have a critical role in designing therapy and in prognostication for patients with metastatic disease localized to the serosal cavities.

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

    From 1966 to 1981, 47 patients with a diagnosis of anal carcinoma were irradiated. This group was composed of 23 males and 24 females, with age ranging from 38 to 84 years (average 64.4 years). Five patients were treated preoperatively and 34 were treated definitively with cancericidal doses of irradiation. Acute radiation reactions requiring a rest-break were noted in 28% of patients, but all were managed as outpatients without untoward chronic sequelae. Chronic complications were noted in 13 patients, including two patients who required colostomy for severe anal stenosis and two who required A-P resection for large painful ulcers. Twenty-eight of 35 patients (80%) treated with irradiation alone have remained locally controlled without further treatment. An additional four have been salvaged by surgery. Only three patients had interstitial implants as part of their treatment course. Actuarial survival at five years for the N/sub 0/ patients and the group as a whole are 95.6 and 79.3%, respectively. It is concluded that external beam irradiation alone, properly fractionated to cancericidal doses, can control anal carcinoma with acceptable morbidity rates and without the use of either chemotherapy or interstitial implants in most cases. There is also a strong correlation suggesting that anal intercourse and male homosexuality play a significant role in the etiology of this disease.

    It was in 1994 when published studies appear that evaluate the utility of the 18 F-FDG PET in the patients with primary tumors of unknown origin (TOD); starting from then diverse studies that support the clinical utility of the study arise with 18 F-FDG PET in the detection of the primary tumor. It is as well as it has been calculated that the study with 18 F-FDG PET is able to detect the primary tumor in around 40% of the patients with negative results in the conventional diagnostic procedures. Until the moment, most of the studies published in relation to the primary tumors of unknown origin only evaluate the paper of the study with 18 F-FDG PET, without including the image fusion technique PET/CT, which has demonstrated in diverse studies; in oncological scenarios different from the TOD, a superior diagnosis certainty.

    Two cases of biopsy-proven conjunctival squamous cell carcinoma (SCC) that developed local and regional spread are described. The cases involved a 65-year-old woman and a 79-year-old man who were initially treated at outside institutions for SCC of the conjunctiva. The patients did not have a history of immune compromise. The female patient presented with direct extension into the lacrimal gland but deferred recommended exenteration. Despite eventual exenteration, she developed metastasis to a neck node 6 months later, which was treated with radiotherapy. The male patient presented with local recurrence and a parotid node metastasis treated with exenteration, parotidectomy, selective neck dissection, and postoperative radiotherapy. Review of the outside pathology of both cases revealed positive tumor margins at the time of original resection. Local control of conjunctival SCC is of critical importance to reduce the risk of orbital extension and regional spread.

    Parathyroid carcinoma is a rare clinical entity, which represents one of the main reasons, why surgery should be performed in specialized centres. Preoperatively, it is very difficult to distinguish between benign and malignant hyperparathyroidism. During the years 1996-2016, we performed 2,220 operations in 2,075 patients with a diagnosis of primary hyperparathyroidism. Among these 2,220 operations, there were 16 operations for parathyroid carcinoma. These 16 operations, including reoperations, were performed in four patients. Two patients had no reoperation, but another 2 patients required 14 reoperations in total. Parathyroid carcinoma was described in 0.2% of all patients with a diagnosis of primary hyperparathyroidism. The number of operations was 0.73% of all operations of primary hyperparathyroidism in years 1996-2016. Prognosis of parathyroid carcinoma is quite favourable, patients evidence a long-term survival rate after the primary operation. However, every reoperation increases the number of possible complications, including recurrent laryngeal nerve injury. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

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

    Full Text Available Primary urethral carcinoma is a rare cancer, comprising <1% of all malignancies. The location of this lesion presents a certain dilemma of treatment between efficacy and quality of life. We report an 84-year-old male patient, with a history of chronic hepatitis C, hypertension, and transient ischemic accident, who presented with dysuria and acute urinary retention. The intravenous urography showed mild prostatic enlargement, but no stone or filling defect was noted in the upper urinary tract. On urethrocystoscopy, multiple papillary tumors were found at the pendulous urethra, and the pathology of biopsy confirmed urothelial carcinoma. The patient was admitted, and electroresection with fulguration of urethral tumors was performed owing to the patient's old age and poor performance status. Intraurethral and intravesical chemotherapy with mitomycin C was regularly given at the outpatient clinic. Recurrent urothelial carcinomas were noted twice in the first 2 years of follow up, and repeated transurethral resections were done. Unfortunately, liver cirrhosis with hepatocellular carcinoma was diagnosed last June, for which he received transcatheter arterial chemoembolization. No recurrence of urethral cancer has been found on semiannual cystoscopy in the past 3 years. Penile-preserving surgery is a reasonable surgical option for elderly primary urethral carcinoma patients with acceptable oncological outcome and good quality of life.

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

    Recent advances in chemoradiotherapy for esophageal carcinoma have resulted in improved survival rates. However, there are few options for recurrent dysphagia due to refractory carcinoma after failure of primary chemoradiotherapy. The aim of this study was to evaluate the safety and efficacy of self-expandable metallic stent placement for patients with recurrent esophageal carcinoma where definitive chemoradiotherapy has failed. Thirteen consecutive patients with recurrent squamous cell carcinoma of the esophagus, in whom self-expandable metallic stents were placed after failure of primary chemoradiotherapy, were studied retrospectively. All patients had esophageal obstruction or malignant fistula. The oral alimentation status of nine of 13 patients (69%) improved after successful placement of the stent. Following placement of the stent, fever (>38 deg C) and severe chest pain occurred in 85% (11/13) of the patients. In all patients examined, C-reactive protein was elevated within 1 week of the operation. Esophageal perforation occurred in three patients. Stent-related mediastinitis and pneumonia developed in six (46%) and three (23%) patients, respectively. Seven of the 13 patients (54%) died of stent-related pulmonary complications. Although the placement of a self-expandable metallic stent for patients with recurrent esophageal carcinoma after failure of chemoradiotherapy improved their oral alimentation status, we found that this treatment increases the risk of life-threatening pulmonary complications.

    2014-03-01

    Full Text Available Primary signet-ring cell carcinoma (SRCC of vermiform appendix is extremely rare; only three cases have been reported in the English literature. An 89-year-old man suddenly presented right lower abdominal pain, and transferred to a hospital, where he was diagnosed with acute appendicitis by physical data, blood data, and CT. He was further transferred to our hospital for emergency operation. Physical examination showed positive abdominal pain, Blunberg sign, and Rosenstein sign. Blood test showed leukocytosis and increased C-reactive protein. An appendectomy was performed. Gross examination during operation showed inflamed appendix, appendiceal adhesion, and acute peritonitis. Gross pathological examination showed no apparent tumor, but the proximal appendix showed wall thickening and luminal occlusion. The appendix was cut into three sections, and was observed under microscopically. Nests of carcinoma cells were seen in the proximal appendix. The carcinoma was composed of SRCC (70% and mucinous carcinoma (30%. The size of carcinoma was 6 × 7 mm. The carcinoma cells invaded into muscular layer. No lymphovascular permeation was seen. The cut margins were negative for carcinoma cells. Immunohistochemically, SRCC cells were positive for cytokeratin (CK AE1/3, CK CAM5.2, CK8, CK18, CK19, CK20, EMA, CEA, CA19-9, p53, Ki-67 (labeling = 30%, CDX2, MUC2, and MUC5AC. They were negative for CK34PE1, CK5/6, CK7, CK14, p63, vimentin, TTF-1, MUC1, MUC 5AC, NSE, synaptophysin, chromogranin, and CD56. No further treatments were performed, because the appendiceal carcinoma was small, the surgical margins were negative and the patient was very old. He was followed up by various imaging modalities. No recurrence or metastasis is found 17 months after the operation.

    Full Text Available Primary Squamous Cell Carcinoma in the kidney is a rare malignant neoplasm associated with nephrolithiasis, typically monobacterial pyonephrosis and rarely Xanthogranulomatous pyelonephritis. It is an aggressive disease with a poor prognosis mostly due to lack of presenting clinical features like a palpable mass, gross haematuria and pain. We report a case presenting with renal calculus and pyonephrosis managed initially with percutaneous nephrostomy followed by nephrectomy due to complete loss of renal function. Histopathological evaluation revealed poorly differentiated squamous cell carcinoma which is managed by chemotherapy, although initially beneficial, patients later develop disseminated metastatic disease which holds a poor prognosis.

    Full Text Available Abstract Background The optimal treatment for pulmonary mucoepidermoid carcinoma (MEC, a rare type of tumor, has not been established yet. This study analyzed the survival of pulmonary MEC patients and attempted to find clues for optimal treatment. Methods A total of 21 patients with pulmonary MEC from November 2004 to January 2011 were included in the investigation. Immunohistochemistry, epidermal growth factor receptor (EGFR mutation, and survival were retrospectively studied. Results Among the 21 pulmonary MEC patients, 17 were diagnosed with low-grade malignancy and 4 with high-grade malignancy through pathological examination. The prognosis was found to be poor in the presence of lymph nodes. The expression rates of EGFR and HER2 were 28.6% and 0%, respectively, which correlated with neither grade nor prognosis. The mutation rate of EGFR was 0. Log-rank test results indicated that age, grade, lymph node metastasis, and tumor-node-metastasis stage were prognostic factors.

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

    Full Text Available Abstract Primary mesenchymal chondrosarcoma of the kidney is rare, and it shows distinct undifferentiated tumor cells and well differentiated cartilagenous components. Also assident infiltrating urothelial carcinoma of the ureter is an extremely rare cancer. We report a case of primary mesenchymal chondrosarcoma occurring in the left kidney with an ipsilateral and distinct distal ureteric implant, and a coexisting infiltrating urothelial carcinoma of the ureter in a 64-year-old man. Histopathological examination and immunohistochemical studuies showed the classic features of mesenchymal chondrosarcoma in kidney, as well as a few infiltrating urothelial in ureter. Multitarget fluorescence in situ hybridization (FISH suggested that the development of the urothelial carcinoma in the ureter may be triggered or induced by the chondrosarcoma component. The patient died 2 month after left nephro-ureterectomy. This is the first reported case of a primary mesenchymal chondrosarcoma of the kidney with coexisting infiltrating urothelial carcinoma of the ureter.

    Full Text Available Abstract Background Despite the fact that metastases are the leading cause of colorectal cancer deaths, little is known about the underlying molecular changes in these advanced disease stages. Few have studied the overall gene expression levels in metastases from colorectal carcinomas, and so far, none has investigated the peritoneal carcinomatoses by use of DNA microarrays. Therefore, the aim of the present study is to investigate and compare the gene expression patterns of primary carcinomas (n = 18, liver metastases (n = 4, and carcinomatoses (n = 4, relative to normal samples from the large bowel. Results Transcriptome profiles of colorectal cancer metastases independent of tumor site, as well as separate profiles associated with primary carcinomas, liver metastases, or peritoneal carcinomatoses, were assessed by use of Bayesian statistics. Gains of chromosome arm 5p are common in peritoneal carcinomatoses and several candidate genes (including PTGER4, SKP2, and ZNF622 mapping to this region were overexpressed in the tumors. Expression signatures stratified on TP53 mutation status were identified across all tumors regardless of stage. Furthermore, the gene expression levels for the in vivo tumors were compared with an in vitro model consisting of cell lines representing all three tumor stages established from one patient. Conclusion By statistical analysis of gene expression data from primary colorectal carcinomas, liver metastases, and carcinomatoses, we are able to identify genetic patterns associated with the different stages of tumorigenesis.

    1984-01-01

    Sixty-two patients with primary carcinoma of the female urethra were treated with a combined radiation therapy (high-dose intracavitary vaginal radium and external beam). Treatment was strictly individualized, but an administered tumor dose of 5500-7000 rad (55-70 Gy) was always attempted. Forty-two patients (67.7%) had tumors of the anterior urethra, and in 20 women (32.3%) the posterior urethra was involved. In 19 patients (30.6%) the clinical diagnosis of lymph node involvement was made. The overall 5-year-survival rate was 64.5%. Patients with anterior urethral carcinoma had a higher 5-year-survival rate (71.4%) than patients with posterior carcinoma (50.0%). The favorable results underline the substantial role of radiation therapy for this malignancy.

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

    Full Text Available Abstract Background Extramedullary plasmacytomas are seldom solitary and usually progress to diffuse myelomatosis. Plasmacytomas of the breast are rare, especially when not associated multiple myeloma. Synchronous infiltrating ductal carcinoma and primary extramedullary plasmacytoma of the breast have not previously reported. Case presentation A 27-years-old woman with an untreated upper outer quadrant breast mass for 1-year was referred to our cancer hospital for surgical evaluation of increasing breast pain. Postoperatively, microscopic examination revealed an infiltrating ductal carcinoma complicated by an extramedullary plasmacytoma divided by fibrous tissue in one section. Following surgery, the patient received chemotherapy for the carcinoma and radiotherapy for the plasmacytoma. Conclusion In this case, careful histopathology examination was essential to make the correct diagnosis and therapy for these synchronous lesions. The patient finished chemotherapy and radiotherapy without significant adverse effects.

    The search for a primary malignancy in patients with a metastatic cervical lymph node is challenging yet ultimately of utmost clinical importance. This study evaluated the efficacy of positron emission tomography computed tomography in detecting the occult primary, within the context of a tertiary referral centre head and neck cancer multidisciplinary team tumour board meeting. Thirty-two patients (23 men and 9 women; mean and median age, 61 years) with a metastatic cervical lymph node of unknown primary origin, after clinical examination and magnetic resonance imaging, underwent positron emission tomography computed tomography. The primary tumour detection rate was 50 per cent (16/32). Positron emission tomography computed tomography had a sensitivity of 94 per cent (16/17) and a specificity of 67 per cent (10/15). Combining these results with those of 10 earlier studies of similar patients gave an overall detection rate of 37 per cent. Positron emission tomography computed tomography has become an important imaging modality. To date, it has the highest primary tumour detection rate, for head and neck cancer patients presenting with cervical lymph node metastases from an unknown primary.

    Objective: To investigate MRI examination methods and imaging manifestations of primary ureteral carcinoma, and to evaluate its clinical values when comparing with other diagnostic imaging facilities. Methods: Eighty-seven cases of primary ureteral carcinoma who were operated within recent 8 years came into the study, among which, 35 cases had MRI examinations. For MRI examination, coronal heavy T 2 WI (water imaging) was performed to show the dilated ureter, then axial T 2 WI and T 1 WI were scanned at the obstruction level. 11 cases underwent additional Gd-DTPA dynamic contrast enhanced scans. The original pre-operative diagnostic reports of various imaging facilities were analyzed comparing with the results of operation and pathology. Results: MRI showed ureteral dilatation in 33 of 35 cases, no abnormal appearance in 1 case, and only primary kidney atrophy post renal transplantation in 1 case. Among the 33 cases with ureteral obstruction, soft mass at the obstruction level was detected on axial scans in 32 cases. The lesions showed gradual and homogeneous mild to moderate enhancement on contrast MRI. The overall employment rate of imaging facilities was as follows: ultrasound (94.3%), IVU (59.8%), CT (52.9%), MRI (40.2%), and RUP (35.6%). The accurate diagnostic rate was as follows :MRI (91.4%), RUP (80.6%), CT (63.0%), ultrasound (47.6%), and IVU (11.5%). Conclusion: Combination of MR water imaging and conventional sequences can demonstrate most primary ureteral carcinoma lesions and has a highest diagnostic accuracy among the current diagnostic imaging facilities. It should be taken as the first diagnostic imaging method of choice when primary ureteral carcinoma is suspected after ultrasound screening

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

    CDC73 mutations frequently underlie the hyperparathyroidism-jaw tumor syndrome, familial isolated hyperparathyroidism (FIHP), and parathyroid carcinoma. It has also been suggested that CDC73 deletion analysis should be performed in those patients without CDC73 mutations. To investigate for CDC73 deletion in a family with FIHP previously reported not to have CDC73 mutations. Eleven members (six affected with primary hyperparathyroidism and five unaffected) were ascertained from the family, and multiplex ligation-dependent probe amplification was performed to detect CDC73 deletion using leukocyte DNA. A previously unreported deletion of CDC73 involving exons 1-10 was detected in five affected members and two unaffected members who were 26 and 39 years of age. Two affected members had parathyroid carcinomas at the ages of 18 and 32 years, and they had Ki-67 proliferation indices of 5 and 14.5% and did not express parafibromin, encoded by CDC73. Primary hyperparathyroidism in the other affected members was due to adenomas and atypical adenomas, and none had jaw tumors. Two affected members had thoracic aortic aneurysms, which in one member occurred with parathyroid carcinoma and renal cysts. A previously unreported intragenic deletion of exons 1 to 10 of CDC73 was detected in a three-generation family with FIHP, due to adenomas, atypical adenomas, and parathyroid carcinomas. In addition, two affected males had thoracic aortic aneurysms, which may represent another associated clinical feature of this disorder.

    Gastric cancers (GC) with methylation of multiple CpG islands have a CpG island methylator phenotype (CIMP) and they can have different biological features. The aim of this study was to investigate the DNA methylation status of GCs and its association with their clinicopathological features. We evaluated the methylation status of four genes (MINT1, MINT2, MINT25 and MINT31) in 105 primary GCs using bisulfite-pyrosequencing analysis. We classified tumors as CIMP-high (CIMP-H), CIMP-low (CIMP-L...

    In conclusion, primary non-urachal enteric-type adenocarcinoma of the urinary bladder is morphologically and immunophenotypically similar – if not identical – to colonic adenocarcinoma. The frequent association of enteric carcinomas of the urinary bladder with intestinal metaplasia and/or colonic-type adenomas with dysplasia suggests possible carcinogenetic pathways similar to that observed in colorectal carcinomas.

    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.

    2013-01-01

    Clear cell carcinoma (CCC) is a rare low-grade carcinoma that represents only 1% to 2% of all salivary glands tumors. The finding of a clear cell tumor in a parotid gland involves the necessity of differential diagnosis between primary clear cell parotid tumors and metastases, mainly from kidney. The biological behavior is not very aggressive and development, which is very slow, is usually asymptomatic and indeed, the tumor often reaches considerable dimensions before being diagnosed. The treatment of choice is the surgical excision. There are rare cases of local recurrence and distant metastases. The aim of this article is to report a primary CCC in the parotid gland that microscopically closely resembled a metastatic CCC of renal origin, making microscopic differentiation difficult.

    Primary surgery is the preferred treatment of T1-T4a sinonasal squamous cell carcinoma (SNSCC). Patients with SNSCC in the National Cancer Data Base (NCDB) were analyzed. Factors that contributed to selecting primary surgical treatment were examined. Overall survival (OS) in surgical patients was analyzed. Four-thousand seven hundred and seventy patients with SNSCC were included. In T1-T4a tumors, lymph node metastases, maxillary sinus location, and treatment at high-volume centers were associated with selecting primary surgery. When primary surgery was utilized, tumor factors and positive margin guided worse OS. Adjuvant therapy improved OS in positive margin resection and advanced T stage cases. Tumor and non-tumor factors are associated with selecting surgery for the treatment of SNSCC. When surgery is selected, tumor factors drive OS. Negative margin resection should be the goal of a primary surgical approach. When a positive margin resection ensues, adjuvant therapy may improve OS. © 2017 Wiley Periodicals, Inc.

    Full text: The purpose of this study was to evaluate the relation between hepatitis B virus surface antigen (HBs antigen) and serum alpha fetoprotein (AFP) levels in patients with liver cirrhosis and primary liver cancer (PLC) in Mali. Between September 1994 to December 1999 a prospective case control study was carried out in Hopital du Point 'G', in 104 patients (27 females, 77 males). Of these 104 patients, 57 were of cirrhosis and 47 of PLC. Age and sex matched 104 healthy controls were also included in the study. HBs antigen, antiHBs antibody and AFP were systematically measured by radioimmunoassay method. HBs antigen was found in 75% of patients as compared to 15.4% in healthy controls (p < 0.01). There was no difference in the frequency of HBs antigen in patients with cirrhosis and PLC. HBs antigen presence was found to be well correlated to AFP level. In fact, 81.5% of our patients with a serum AFP level greater than the normal value were HBs antigen positive. Of the 63% patients having AFP serum concentration greater than 8 times of our laboratory standardizes normal value, only 4 patients (6.3%) were negative for HBs antigen. AFP serum concentration greater than 16 times of the normal value was found only in HBs antigen patients. In our opinion, this data gives a new element to the role of Hbs antigen in the pathogenesis of liver cirrhosis and PLC. (author)

    Full text: To determine the overall survival and gastrointestinal toxicity for patients treated with salvage definitive chemo-radiotherapy after primary surgery for locoregional relapse of oesophageal carcinoma. A retrospective review of 525 patients who had a resection for oesophageal or oesophagogastric carcinoma at Princess Alexandra Hospital identified 14 patients treated with salvage definitive radiotherapy or chemo-radiotherapy, following localized recurrence of their disease. We analysed the patient and treatment characteristics to determine the median overall survival as the primary end point. Gastrointestinal toxicity was examined to determine if increased toxicity occurred when the stomach was irradiated within the intrathoracic radiotherapy field. The median overall survival for patients treated with curative intent using salvage definitive chemo-radiotherapy was 16 months and the 2-year overall survival is 21%. One patient is in clinical remission more than 5 years after therapy. Age <60 years old and nodal recurrence were favourable prognostic factors. Treatment compliance was 93% with only one patient unable to complete the intended schedule. Fourteen per cent of patients experienced grade 3 or 4 gastrointestinal toxicity. Salvage definitive chemo-radiotherapy should be considered for good performance status patients with oesophageal carcinoma who have a locoregional relapse after primary surgery. The schedule is tolerable with low toxicity and an acceptable median survival

    Objective: To investigate the effect of cryotherapy of employing Argon/Helium assisted with TACE for the unresectable primary liver carcinoma. Methods: 124 cases with primary liver carcinoma were randomly divided into two groups: 60 cases were treated by TACE and cryotherapy; the other 64 cases were simply done by TACE as control. In general, TACE was undertaken once a month and altogether three times for a course. Cryotherapy was undergone 1-3 times for a course. Results: The total effective rates (CR + PR) were 45.3% for the control group and 68.3% for the combined therapy group, with an obvious difference between the two groups, 0.5, 1, 1.5 years survival rate were 81.3%, 62.5%, 43.8% respectively in the control group; 93.3%, 83.3%, 63.3% respectively for the combined group. There was an obvious difference between the two groups of 1, 1.5 years of survival rates. Conclusions: Cryotherapy of employing Argon/Helium assisted with TACE for the unresectable primary liver carcinoma is feasible with raising the effective rate and prolonging survival time. (authors)

    Transitional cell carcinoma (TCC) of the female urethra is a rare urological malignancy, and intracranial metastasis of this cancer has not yet been reported in the literature. This review is intended to present a case of multiple intracranial metastasis in a female patient with a remote history of primary urethral TCC. A 49-year-old woman, presented with a prolapsed mass in urethral orifice that was diagnosed as primary urethral TCC with distant lung and multiple bone metastases. The patient subsequently underwent chemotherapy under various regimens. A year later, the patient developed headache and vomiting which as was found to be due to multiple intracranial metastasis. The patient underwent surgical resection of the largest lesion located on the cerebellum, and consecutively gamma knife radiosurgery was performed for other small-sized lesions. Pathological examination of the resected mass revealed a metastatic carcinoma from a known urethral TCC. Serial work-up of systemic metastasis revealed concomitant aggravation of lung, spleen, and liver metastasis. The patient died of lung complication 2 months after the diagnosis of brain metastasis. To the best of our knowledge, this is the first reported case of cerebral metastasis from primary urethral TCC, with pathological confirmation. As shown in intracranial metastasis of other urinary tract carcinoma, this case occurred in the setting of uncontrolled systemic disease and led to dismal prognosis in spite of aggressive interventional modalities

    Full Text Available Primary carcinoma of the fallopian tube is rare and accounts for about 0.14-1.8% of all gynecological malignancies. Correct diagnosis is rarely made preoperatively as clinically tubal carcinoma closely resembles ovarian carcinoma. Here, we report two cases of bilateral primary fallopian tube carcinomas. Case 1: A 54-year-old female presented with postmenopausal bleeding, abdominal pain, and pervaginal watery discharge for 10 days. Ultrasonography (USG of pelvis showed endometrial thickening and multiple tiny echogenic foci in omentum suggestive of omental cake. With a provisional diagnosis of endometrial carcinoma, total abdominal hysterectomy with bilateral salpingo-oophorectomy and omentectomy was done. On gross examination, small and rudimentary right ovary was adherent to the fimbrial end of the tube. Left-sided tubo-ovarian mass was present, cut section of which showed yellowish solid area in tubal wall and encroaching on ovarian surface. On histological examination, sections from the fimbrial end of both fallopian tubes showed features of papillary serous adenocarcinoma. Case 2: 70-year-old lady, 15 years postmenopausal presented with gradual onset pain and swelling of abdomen, urinary incontinence since 4 days. USG showed bulky uterus, 5 cm × 2 cm fibroid, bilateral tubes, and ovaries were not visualized. Serum cancer antigen-125 was raised (159.7 U/ml. Total hysterectomy and bilateral salpingo-oophorectomy with infracolic omentectomy was done. On gross examination, ovaries were firmly attached to tubes and no apparent solid area was noted. On microscopy, papillary serous adenocarcinoma arising from tubal wall was seen infiltrating focally into ovarian stroma; tubal epithelium showed dysplastic change. Sections from omentum showed numerous psammoma bodies.

    2013-01-01

    Full Text Available Primary squamous cell carcinoma of the thyroid is an extremely rare neoplasm with aggressive behavior. Until date, only around 60 cases have been reported in the literature. Primary treatment of the patient is radical surgery. With optimum treatment survival is not more than 6 months in this aggressive malignancy. However in our patient surgery it was not possible because of unresectability of the mass due to encroachment of major vessels. Hence, we have delivered radiotherapy alone, with which effective palliation could be achieved and patient is leading a good quality-of-life for last 1 year.

    Full Text Available Primary squamous cell carcinoma of breast is a rare disease. Incidence for primary SCC breast is 0.04-0.1 % of all malignancies of breast. A pure form of primary SCC breast is also described and its incidence is still less. Biologically it behaves differently and usually doesn’t metastasize to lymph nodes, though distant metastasis is more common. They occur usually in elderly women. Mean age of presentation is 54 years. We report the youngest patient so far - a 27 years old woman diagnosed initially as having fibrocystic disease and later as primary pure SCC breast. She did not have any other focus of malignancy in the body and is doing well 3-1/2 years post surgery and radiotherapy.

    AIMS: To report two cases of lymph node enhancement in primary hepatic carcinoma following the administration of Mangafodipir trisodium (MnDPDP, Teslascan[reg ], Nycomed Amersham U.K.), an hepatocyte specific magnetic resonance imaging (MRI) contrast agent. To review our experience with this contrast agent and the literature to establish if such enhancement occurs in normal lymph nodes or has been previously described in hepatocellular carcinoma (HCC) or other lesions. MATERIALS AND METHODS: The radiological reports of all MnDPDP enhanced abdominal MRI examinations were reviewed for lymph node enlargement. The MR images from examinations with reported nodal enlargement were re-evaluated for evidence of nodal enhancement and the hospital notes and histological reports were reviewed. Nodal enhancement was considered present if lymph node signal intensity was greater than that of the spleen following MnDPDP. Literature searches were performed on Medline and PubMed for previous descriptions of lymph node enhancement following MnDPDP. RESULTS: The reports of 90 MnDPDP abdominal MRI examinations were reviewed. Of 18 cases of lymph node enlargement, two had evidence of lymph node enhancement following MnDPDP. These two cases had hepatocellular carcinoma and fibrolamellar hepatocellular carcinoma, respectively, confirmed on liver biopsy. No reports of lymph node enhancement following MnDPDP were identified in the literature. CONCLUSION: Two cases of lymph node enhancement following MnDPDP have been presented. Although histological confirmation of the lymph nodes was not obtained, the authors propose that the lymph node enhancement was due to functioning hepatocytes in lymph node metastases from the patients' histologically confirmed hepatocellular carcinomas.

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

    Full Text Available Primary squamous cell carcinoma of the breast (SCCB is a very rare malignancy of the breast and is generally aggressive. It is even rarer during the gestational period. Only few cases have been reported during pregnancy and lactation (Rokutanda et al., 2000. SCCB seen within the gestational period tends to be very aggressive and has a larger size than other breast carcinomas. Pure SCCB is derived from the epidermis of the breast, nipple, or metaplasia on chronic inflammatory background (Bige et al., 2007, such as complicated breast cyst, dermoid cyst, or abscess. We report a case of SCCB in a 30-year-old primigravida that had an aggressive propensity and fatal outcome.

    Full Text Available We report the case of an 86-year-old man with primary gastric small cell carcinoma (SmCC. He was admitted to our hospital owing to gastrointestinal bleeding complicated by anemia. An upper gastrointestinal endoscopic examination revealed a large, irregularly ulcerated tumor on the upper to middle body of the stomach. Small cell carcinoma was diagnosed based on the results of histologic and immunohistochemical studies of an endoscopic biopsy specimen. According to previous reports of gastric SmCC, only one-sixth of cases have been correctly diagnosed preoperatively. In our case, it was an aggressive malignancy that had an extremely poor prognosis. We believe that careful endoscopic examination including immunohistochemical investigation is necessary to accurately diagnose gastric SmCC in clinical practice.

    Primary intraosseous squamous cell carcinoma (PIOSCC) is a rare carcinoma, which arises within the jaws without connection to the oral mucosa and presumably develops from a remnant of odontogenic epithelium. We present a case of solid type PIOSCC in a 52-year-old male patient complaining of dull pain on his left lower molar. In this case, early stage PIOSCC mimicking a periapical lesion might lead to a one-year delay in treatment due to the misdiagnosis of osteomyelitis after extraction of the third molar. The clinical, radiological, and histologic features are described. In this case, there was initial radiographic evidence for PIOSCC mimicking a periapical lesion. Incautious radiographic interpretation and treatment procedures had delayed the correct diagnosis and resulted in extensive bony destruction during the patient's disease progression.

    Full Text Available Merkel cell carcinoma (MCC is a rare and highly aggressive neuroendocrine tumor of the skin which almost exclusively presents as a solitary tumor. It is most often seen on sun-exposed regions, historically almost exclusively on the head and neck, with only rare case reports on the extremities. Although recent studies have shown increased incidence with up to 20% on the extremities, here we present one of these rare emerging presentations, with the addition of a unique treatment option. Our patient is an 80-year-old male with a 3-month history of multiple raised, rapidly enlarging tumors on the right ankle. Two separate biopsies were performed and demonstrated sheets and clusters of small blue cells filling the dermis with scant cytoplasm, dusty chromatin, and nuclear molding. Subsequent immunohistochemical stains confirmed the diagnosis of multiple primary MCC. Despite the characteristic immunohistochemical profile of primary MCC, the possibility of a metastatic neuroendocrine carcinoma from an alternate primary site was entertained, given his unusual clinical presentation. A complete clinical workup including CT scans of the chest, abdomen, and pelvis showed no evidence of disease elsewhere. Instead of amputation, the patient opted for nonsurgical treatment with radiation therapy alone, resulting in a rapid and complete response. This case represents an unusual presentation of primary MCC and demonstrates further evidence that radiation as monotherapy is an effective local treatment option for inoperable MCC.

    Primary peritoneal serous carcinoma (PPSC) is a rare neoplasm histologically indistinguishable from ovarian serous carcinoma primarily occurring in the female population. To date, extremely rare cases of PPSC have been reported in men; however, diagnosis by cytology has yet to be described. Here we present the clinical, radiographic, cytomorphologic, histologic and immunohistochemical (IHC) findings of a high-grade (HG) PPSC in a 70-year-old man with a history of prostatic adenocarcinoma. Core needle biopsy (CNB) touch preparation smears showed pleomorphic, round, columnar and polygonal epithelioid cells present singly or arranged in loosely cohesive three-dimensional clusters. The tumor cells are characterized by enlarged nuclei containing prominent nucleoli, and variable scant to moderate, slightly dense cytoplasm. Scattered cells contained cytoplasmic vacuoles. Examination of CNB revealed an infiltrating tumor in sheets with focal papillary configuration. Tumor cells were morphologically consistent with HG carcinoma. IHC studies demonstrated diffuse positivity for CK7, PAX-8, ER, WT1, p53, p16 and BerEP4 with focal/weak staining for calretinin and CK5/6, which supporting the diagnosis of HG PPSC. The patient was treated with 6 cycles of carboplatin and paclitaxel with near resolution of the mass at 10 month follow-up. To the best of our knowledge, this is the first reported case in the literature of PPSC in a man diagnosed by cytology. This article is protected by copyright. All rights reserved.

    With age, oestradiol receptor concentrations increased in primary breast carcinoma while age did not seem to affect the progesterone receptor levels. Above the age of 70, all tumours examined proved to be hormone-dependent. Analysis by light microscope did not allow correlation of the receptor-positive tumours to any specific or predominant cellular structure. Presurgical radiotherapy of 20 gray significantly reduced the oestradiol and to an even greater extent the progesterone receptor concentrations in the tumours. Prebioptic irradiation with 8 gray accentuated the inhibition of steroid receptor proteins. This reduction in receptor concentration after radiotherapy should be taken into account when interpreting steroid receptor values. (author)

    Full Text Available Sjogren%u2019s syndrome is a chronic autoimmune disease characterized by xerostomia and xerophthalmia, known as the %u2018sicca symptoms%u2019. Patients with Sjogren%u2019s syndrome, characteristically have positive nuclear and cytoplasmic antigens, typically Anti-Ro/SSA and Anti-La/SSB because of lymphocytic infiltration of the exocrine glands. Patients with primary Sjogren%u2019s syndrome, develop systemic complications, non-Hodgkin lymphoma being the most feared of these. We describe here a case of Sjogren%u2019s syndrome with basal cell carcinoma, which presented with an ulcerated lesion on nasal dorsum.

    2009-02-01

    Small-cell carcinoma of a minor salivary gland is a rare and to the best of our knowledge previously unreported cause of vocal fold immobility. We describe the case of a 68-year-old woman who presented with hoarseness, dysphagia, and weight loss. Examination revealed left vocal fold immobility. She had no other obvious abnormality of the upper airway, neck, or skin. Computed tomography and magnetic resonance imaging demonstrated a 4-cm submucosal oropharyngeal mass with extension to the parapharyngeal space and involvement of the carotid sheath and the foramen ovale at the skull base; imaging also revealed cervical adenopathy. Fine-needle aspiration biopsy identified the mass as a small-cell carcinoma, a finding that was confirmed by immunohistochemistry. Extensive tumor invasion and multiple comorbidities precluded an aggressive management strategy, and the patient was treated palliatively. She died of her disease shortly after her diagnosis. Vocal fold immobility of unknown etiology mandates imaging from the skull base to the upper mediastinum.

    Full Text Available Unsatisfactory effects of treatment of laryngeal carcinoma patients stimulate the clinicians as well as researchers to develop new more effective treatment models and to find new reliable prognostic factors. The aim of the present study was the evaluation of the use of primary cell cultures of the laryngeal carcinoma and laser scanning cytometry (LSC in the assessment of tumor reactivity to cisplatinum. Nineteen primary cultures of laryngeal carcinoma cells established from fragments of laryngeal carcinoma infiltrations were cultured with or without cisplatin, stained with monoclonal antibodies against P53 and BCL-2 proteins and analyzed by LSC. Cisplatin added to the culture medium leads to the significant increase of P53 expression and decrease of BCL-2 expression. Moreover, changes of P53 and BCL-2 expressions were significantly correlated. Our findings of apoptosis regulatory mechanisms could be useful in patient qualification for the chemotherapeutic follow-up treatment.

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

    2005-01-01

    The primary control of upper gingiva and hard palate squamous cell carcinoma was evaluated clinically. From 1985 to 1999, there were 51 cases that received definitive treatment in our hospital with a primary control rate of 70.6%. The primary control rates according to treatment modality were: 73.3% for surgery alone (69.2% for partial maxillectomy, 80% for total maxillectomy); 71.4% for definitive radiation therapy; and 68% for combined surgery and radiation therapy. The primary control rates according to the T stage were: 85.7% for T1; 60% for T2; 77.8% for T3; and 80% for T4. In general, primary control was better when the tumor was located anteriorly rather than posterolaterally in the oral cavity. Frequent recurrent sites following the operation were the infratemporal fossa and/or the pterygopalatine fossa, especially when the tumor had been located posterolaterally. In such cases, a salvage operation was often impossible, and the uncontrollable primary lesion progressed and caused death. Therefore, when the tumor is located posterolaterally, and especially if it has invaded deeply into the infratemporal fossa and the pterygopalatine fossa, it is vitally important to properly plan the surgical approach and to ensure a good visual operative field.

    Full Text Available Background: In the era of well-developed site-specific treatment strategies in cancer, identification of occult primary is of paramount importance in CUP patients. Furthermore, exact determination of the extent of the disease may help in optimizing treatment planning. The aim of the present study was to investigate additional value of F-18 FDG PET/CT in patients with cancer of unknown primary (CUP as an appropriate imaging tool in early phase of initial standard work up.Materials and Methods: Sixty-two newly diagnosed CUP patients with inconclusive diagnostic CT scan of chest, abdomen and pelvis referring for F-18 FDG PET/CT were enrolled in this study. Standard of reference was defined as histopathology, other diagnostic procedures and a 3-month formal clinical follow up. The results of PET/CT were categorized as suggestion for primary site and additional metastasis and classified as true positive, false positive, false negative and true negative. The impact of additional metastasis revealed by F-18 FDG PET/CT on treatment planning and the time contribution of F-18 FDG PET/CT in diagnostic pathway was investigated.Results: Sixty-two patients with mean age of 62 (30 men, 32 women, PET/CT correctly identified primary origin in 32% with false positive rate of 14.8%. No primary lesion was detected after negative PET/CT according to standard of reference. Sensitivity, Specificity and accuracy were 100%, 78% and 85%, respectively. Additional metastatic site was found in 56% with 22% impact on treatment planning. Time contribution for PET/CT was 10% of total diagnostic pathway.Conclusion: Providing higher detection rate of primary origin with excellent diagnostic performance, shortening the diagnostic pathway and improving treatment planning, F-18 FDG PET/CT may play a major role in diagnostic work up of CUP patients and may be recommended as an alternative imaging tool in early phase of investigation.

    Aim: The aim of this study was to evaluate the role of whole body PET/CT scan with 1 8F -fluorodeoxyglucose (FDG) in the detection of the primary tumor in patients with metastatic cancer from unknown primary origin (CUP syndrome). Methods: Sixty-eight consecutive patients, with CUP syndrome (39 lymph nodes, 29 visceral biopsy proven tumor metastases), underwent a whole-body FDG-PET/CT study. All enrolled patients were unsuccessfully studied, within the previous month, with physical examination, laboratory tests and conventional diagnostic procedures. All the pathological findings identified at PET/CT scan and suspected for primaries, were further investigated. After PET study, the minimum follow-up period for the inclusion in the studied population was 3 months. Results: The primary tumor site was correctly identified by FDG-PET/CT in 24 patients (24/68, 35.3%): long (0-9). rino/oro-pharynx (n=6), pancreas (n=5), colon (n=2). uterus (n=2). In 5 cases, FDG-PET scan did not identify a primary pathological focus, which was subsequently detected by other diagnostic methods within 3 months. In 39 patients (39168, 57.4%), the primary tumor site was not localized. However, in 9 of them, FDG-PET/CT scan identified further unexpected metastases, modifying the stage of disease. Overall, the following oncological treatment was influenced by the PET scan, in a total of 33 patients (33/68, 48.5%). Conclusion: Our data strongly support the diagnostic contribution of whole body FDG-PET/CT scan in the evaluation of patients with CUP syndrome and suggest its use in an early phase of the diagnostic iter to optimize patient management

    Primary ectopic breast carcinoma is a rare disease and, at present, no specific guidelines on its diagnosis and treatment are available. The purpose of this article is to review the world literature in English on primary ectopic breast carcinoma located in the armpit and to offer guidelines for diagnosis and treatment. Data for this review were identified by searches of MEDLINE, PubMed, The Cochrane Library, ACNP (Italian catalogue of journals) and references from relevant articles using relevant search terms and data published in the previous reviews. Primary ectopic breast carcinoma of the axilla mostly affects women of over 40 (range 28-90 yrs) years of age. The most frequent histological diagnosis is invasive ductal carcinoma not otherwise specified (NOS) (72%). Because of its rareness, in most cases, the diagnosis is delayed for on average 40.5 months. This disease is rare, but a high level of suspicion for carcinoma is mandatory when confronted with a tumour in this area. Once diagnosed, patients should undergo staging, and prognostic and adjuvant treatment procedures identical to orthotopic breast carcinoma guidelines. There are some limitations for the staging. Loco-regional treatment, on indication, combined with endocrine therapy and/or chemotherapy seems the treatment of choice.

    Full Text Available 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.

    Objective: To study the significance of E-cadherin (E-cad) expression of primary hepatocellular carcinoma (PHC), and the effect of the different chemo-embolization treatment on E-cad. Methods:Ninety-eight histopathological verified PHC specimens were obtained. The patients were treated with surgical resection alone (57 cases), and second stage surgical resection after four kinds of chemo-embolization (41 cases). Strept avidin-biotin complex (SABC) immunohistochemical staining with monoclonal antibody against human E-cad was used to observe the E-cad in all specimens. The experimental results were compared with the surgical and clinical findings. Results: The metastatic rates in E-cad (+) and (-) were 43.3%, 70.4% respectively (x 2 = 4.22, P 0.05). The E-cad expression of trabecular and clear cell PHC was higher than that of solid and poorly differentiated PHC. After chemo-embolization, the E-cad expression of the former decreased, the latter increased. The E-cad expression decreased as pathologic grades increasing. After chemo-embolization, the E-cad expression increased as pathological grades increasing. The metastatic rates in interventional group and surgical resection alone were 48.8%, 56.1% respectively (P > 0.05). Conclusions: The increased expression of E-cad would restrain PHC from metastasis. It could act as a prognosis-predictive marker. The effect of chemo-embolization on E-cadherin expression of primary hepatocellular carcinoma had histopathologic difference

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

  9. Primary merkel cell carcinoma clinically presenting as deep oedematous mass of the groin

    Full Text Available Abstract Merkel cell carcinoma (MCC is a relatively rare, polyomavirus associated, primary neuroendocrine carcinoma of the skin which is usually arising from dermal skin layers. However, the origin of MCC in the subcutaneous tissue is debatable. We report a 58-yearold female patient with an oedematous mass on her left groin that was firm in consistency and had no discoloration or other visible abnormality of the overlying skin. On histology and immunohistology the tumour was consistent with the diagnosis of MCC showing a predominant subcutanous growth pattern. Pelvic magnetic resonance tomography revealed a tumour conglomerate reaching from the subcutis of the left groin to the left paraaortal and parailiacal region indicating widespread lymphogenic metastisation. Despite complete medical work-up no other MCC primary could be detected. In conclusion, predominant subcutaneous growth pattern as well as tumour localization in the groin are uncommon features of MCC. MCC showing the aforementioned features may be associated with significant delay of diagnosis and therefore represents an unfavourable prognostic factor.

    Background Primary mucinous carcinoma of the skin (PMCS) is a rare malignant tumor deriving from the sweat glands. It is typically located on the head and is often mistaken for a metastasis from a more common primary tumor of the breast or gastrointestinal tract. We present the first population......-based study of PMCS. Materials and methods Data on PMCS was obtained from the Danish Cancer Registry, which has recorded incident cases of cancer on a nationwide basis since 1943. We extracted all patients diagnosed 1978-2003 with PMCS. Results Fifteen cases of PMCS have been registered during the study...... or PMCS related deaths were reported. Conclusion PMCS is a rare, slow-growing tumor which rarely metastasizes and is associated with low mortality. The age-standardized incidence rate, based on data from a population-based cancer registry of high quality and validity, is less than 0.1 per million. However...

    Tumor-infiltrating lymphocytes and immune checkpoint proteins such as PD-L1 are potential prognostic factors and therapeutic targets in breast cancer. Most studies characterizing the breast tumor immune microenvironment have focused on ductal carcinomas. Here we investigate the tumor microenvironment of primary invasive lobular carcinomas. Previously constructed tissue microarrays of 47 lobular carcinomas were labeled by immunohistochemistry for PD-L1, CD8, CD20, and FoxP3. The stromal immune infiltrate density was qualitatively scored as a percentage of tumor area: 1+ (50%). The average immune cell subtype per high-power field was quantitatively scored. The percentage PD-L1 labeling on tumor-infiltrating lymphocytes was scored as none, focal (lobular carcinomas contained PD-L1 + tumor-infiltrating lymphocytes with the majority showing 1+ immune infiltrates with focal-moderate PD-L1 labeling. PD-L1 was expressed by tumor cells in 17% of lobular carcinomas. In contrast to ductal carcinomas, there was no correlation between the immune infiltrate density, the PD-L1 expression by lobular carcinoma cells, tumor grade, or the expression of estrogen receptor or human epidermal growth factor receptor-2. However, both the tumor-infiltrating lymphocyte density and the average CD8 + T-cell counts correlated with immune cell PD-L1 status (P=0.004 and 0.03, respectively). Similar to breast ductal carcinomas, PD-L1 + lobular breast carcinomas had higher numbers of PD-L1 + tumor-infiltrating lymphocytes (63%) than PD-L1 - lobular carcinomas (23%; P=0.04). These data show that a subset of primary breast lobular carcinomas both express PD-L1 on tumor cells and contain PD-L1 + tumor-infiltrating lymphocytes, suggesting the possibility of both constitutive and adaptive PD-L1 expression. Together, these results support immunotherapy as a potential treatment for a subset of patients with primary invasive lobular breast carcinomas.

    Little is known about patterns of care after a cancer of unknown primary (CUP) diagnosis. We performed a retrospective cohort study to describe and compare the treatment, health service use and survival of patients with CUP and metastatic cancer of known primary among 143,956 Australian Government Department of Veterans' Affairs clients, 2004-2007. We randomly matched clients with CUP (C809; n=252) with clients with a first diagnosis of metastatic solid cancer of known primary (n=980). We ascertained health services from the month of diagnosis up to 2 months post-diagnosis for consultations, hospitalizations and emergency department visits, and up to 1 year for treatment. We compared cancer treatments using conditional logistic regression; consultation rates using negative binomial regression; and survival using stratified Cox regression. 30% of CUP patients and 70% of patients with known primary received cancer treatment and the median survival was 37 days and 310 days respectively. CUP patients received fewer cancer medicines (odds ratio (OR)=0.54, 95% confidence interval (CI) 0.33-0.89) and less cancer-related surgery (OR=0.25, 95% CI 0.15-0.41); males with CUP received more radiation therapy (OR=2.88, 95% CI 1.69-4.91). CUP patients had more primary care consultations (incidence rate ratio (IRR)=1.25, 95% CI 1.11-1.41), emergency department visits (IRR=1.86, 95% CI 1.50-2.31) and hospitalizations (IRR=1.18, 95% CI 1.03-1.35), and a higher risk of death within 30 days (hazard ratio=3.30, 95% CI 1.69-6.44). Patients with CUP receive less treatment but use more health services, which may reflect underlying patient and disease characteristics. Copyright © 2015 Commonwealth of Australia.

    Chun-Ping Wu

    Full Text Available Cancer stem-like side population (SP cells have been identified in many solid tumors; however, most of these investigations are performed using established cancer cell lines. Cancer cells in tumor tissue containing fibroblasts and many other types of cells are much more complex than any cancer cell line. Although SP cells were identified in the laryngeal squamous cell carcinoma (LSCC cell line Hep-2 in our pilot study, it is unknown whether the LSCC tissue contains SP cells. In this study, LSCC cells (LSCCs were primary cultured and purified from a surgically resected LSCC specimen derived from a well-differentiated epiglottic neoplasm of a Chinese male. This was followed by the verification of epithelium-specific characteristics, such as ultrastructure and biomarkers. A distinct SP subpopulation (4.45±1.07% was isolated by Hoechst 33342 efflux analysis from cultured LSCCs by using a flow cytometer. Cancer stem cell (CSC-associated assays, including expression of self-renewal and CSC marker genes, proliferation, differentiation, spheroid formation, chemotherapy resistance, and tumorigenicity were then conducted between SP and non-SP (NSP LSCCs. In vitro and in vivo assays revealed that SP cells manifested preferential expression of self-renewal and CSC marker genes, higher capacity for proliferation, differentiation, and spheroid formation; enhanced resistance to chemotherapy; and greater xenograft tumorigenicity in immunodeficient mice compared with NSP cells. These findings suggest that the primary cultured and purified LSCCs contain cancer stem-like SP cells, which may serve as a valuable model for CSC research in LSCC.

    Patients with spinal metastasis from cancer of unknown primary origin have limited life expectancy and poor quality of life. Surgery and radiation therapy remain the main treatment options, but, to our knowledge, there are limited data concerning quality-of-life improvement after surgery and radiation therapy and even fewer data on whether surgical intervention would affect quality of life. Patients were enrolled between January 2009 and January 2014 at the Changzheng Hospital, Shanghai, People's Republic of China. The quality of life of 2 patient groups (one group that underwent surgery followed by postoperative radiation therapy and one group that underwent radiation therapy only) was assessed by the Functional Assessment of Cancer Therapy-General (FACT-G) questionnaire during a 6-month period. A subgroup analysis of quality of life was performed to compare different surgical strategies in the surgical group. A total of 287 patients, including 191 patients in the group that underwent surgery and 96 patients in the group that underwent radiation therapy only, were enrolled in the prospective study; 177 patients completed all 5 checkpoints and 110 patients had died by the final checkpoint. The surgery group had significantly higher adjusted quality-of-life scores than the radiation therapy group in each domain of the FACT-G questionnaire (all p quality of life in patients with spinal metastasis from cancer of unknown primary origin in the 6-month assessment. In terms of surgical strategies, circumferential decompression seems better than laminectomy alone in quality-of-life improvement. Therapeutic Level II.

    Gastro-entero-pancreatic neuroendocrine tumors (GEPNETs) are increasing in incidence, and accurate staging is important for selecting the appropriate treatment. (68)Ga-DOTATATE imaging is a promising approach for detecting GEPNETs and could help in selecting optimal therapeutic strategies. The aim of this study was to prospectively determine the clinical utility of (68)Ga-DOTATATE positron emission tomography (PET)/computed tomography (CT) in detecting unknown primary and metastatic GEPNETs. One hundred thirty-one patients were enrolled in a prospective study of patients undergoing (68)Ga-DOTATATE PET/CT, (111)In-pentetreotide single-photon emission computed tomography (SPECT)/CT and multiphasic CT scan, and/or magnetic resonance imaging in a blinded fashion with comprehensive biochemical testing. The primary outcome measure was the detection of lesions by each imaging study. (68)Ga-DOTATATE PET/CT imaging detected 95.1% of lesions (95% CI, 92.4% to 96.8%) with an average maximum standardized uptake value of 65.4 ± 47 (range, 6.9 to 244), anatomic imaging detected 45.3% of lesions (95% CI, 37.9% to 52.9%), and (111)In-pentetreotide SPECT/CT detected 30.9% of lesions (95% CI, 25.0% to 37.5%), with a significant difference between imaging modalities (P < .001). In four of 14 patients (28.6%), (68)Ga-DOTATATE PET/CT found a previously unknown primary tumor, and detected primary GEPNET, lymph node, and distant metastases correctly in 72 of 113 lesions (63.7%) when compared with histopathology, with 22.1% and 38.9% detected by using (111)In-pentetreotide SPECT/CT and anatomic imaging, respectively. On the basis of findings with (68)Ga-DOTATATE PET/CT, 43 of 131 patients (32.8%) had a change in management recommendation. In patients with carcinoid symptoms but negative biochemical testing, (68)Ga-DOTATATE PET/CT detected lesions in 65.2% of patients, 40% of which were detected neither by anatomic imaging nor by (111)In-pentetreotide SPECT/CT.

    Primary squamous cell carcinomas arising from the thyroid gland (SCCTh) is extremely rare diseases, which have never been fully studied. Thus, we performed a systematic review and individual participant data meta-analysis of published SCCTh cases, to understand the clinical characteristics and to identify the prognostic factors of primary SCCTh. A literature search was conducted within Medline, EMBASE, Cochrane library databases and KoreaMed using the following Medical Subject Headings (MeSH) keywords: “primary,” “squamous,” “carcinoma,” “cancer,” and “thyroid.” Eighty-four patients' individual data from 39 articles and five patients' data in our institute were selected for analysis (N = 89). The mean age at diagnosis was 63.0 years (range, 24–90) and female preponderance (M:F = 1:2) was noted. The commonest complaint was the anterior neck mass, followed by dyspnea or dysphagia, and extension to the adjacent structure was found in 72%. The median survival was 9.0 months (95% CI, 6.0–23.0) and 3-year survival rate (3YSR) was 37.6% by Kaplan–Meier method, but only 20.1% by a shared frailty model for adjusting heterogeneity. Complete resection (R0) of tumors was the only significant prognostic factor in multivariable analysis, and the benefit of adjuvant treatment was not proved. The prognosis of patients with SCCTh is very poor (20% in 3YSR), but complete resection of disease is correlated with improved survival. To achieve complete surgical eradication of tumors, early detection and accurate diagnosis should be emphasized

    Full Text Available Background. Sweat gland carcinoma is a rare malignancy with a high metastatic potential seen more commonly in elderly patients. The scalp is the most common site of occurrence and it usually spreads to regional lymph nodes. Liver, lungs, and bones are the most common sites of distant metastasis. Late lung metastasis of sweat gland adenocarcinoma after a time span of 5 years is extremely rare. Aim. We report a patient with late lung metastasis of a primary sweat gland carcinoma 10 years after initial surgical resection. Conclusion. Sweat gland carcinomas are rare cancers with a poor prognosis. Surgery in the form of wide local excision and lymph node dissection is the mainstay of treatment. Late pulmonary metastases with a latency of 10 years have never been reported in the literature. This is the first clinical documentation of late lung metastasis from sweat gland carcinoma with a latency period of 10 years.

    Full Text Available We are describing a 19-year-old white woman who presented with two synchronous primary cancers, namely glioblastoma multiforme and papillary thyroid cancer. The patient was admitted with dizziness, headache, and vomiting. CT head revealed acute intraparenchymal hematoma in the right cingulate gyrus and the splenium of the corpus callosum. Carotid and cerebral angiogram were unremarkable. MRI of the brain demonstrated a non-enhancing and non-hemorrhagic component of the lesion along the lateral margin of the hemorrhage just medial to the atrium of the right lateral ventricle that was suspicious for a tumor or metastasis. Brain biopsy confirmed it as glioblastoma mutiforme. CT chest was done to rule out primary cancer that revealed a 11 mm hypodense lesion in the left lobe of the thyroid and ultrasound-guided fine-needle aspiration biopsy confirmed it as papillary thyroid carcinoma. We should evaluate for multiple primary malignancies in young patients who are found to have primary index cancer.

    Full Text Available Abstract Background Primary Non-Hodgkin's Lymphoma (PHNL of the breast is a rare entity, while secondary involvement of the breast with diffuse disease of Non-Hodgkin's lymphoma (NHL is more common. However, PNHL is the most frequent haematopoietic tumour of the breast. Diagnostic criteria for PNHL of the breast are presence of technically adequate pathologic specimens, close association of mammary tissue and lymphomatous infiltrate, no prior diagnosis of an extarammamary lymphoma, and no evidence of concurrent widespread disease, except for ipsilateral axillary lymph nodes if concomitant with the primary lesion. Case presentation A 57-year-old woman was recalled because her screening mammograms revealed three separate lesions in her right breast and one in the left. Histology of the lesions confirmed lymphoma in one breast with ductal carcinoma in the other. Conclusion Most of reported cases in literature have been involving the right breast, and almost all the patients were females. NHLs of the breast typically present as unilateral mass; the frequency of bilateral disease at first presentation ranges from 5–25%. Our objective is to report a case of primary lymphoma of the breast involving both axillae with concomitant bilateral primary breast cancer which has not been reported yet to our best of knowledge in literature.

    The aim of the study was to investigate the efficacy of hyperfractionation as altered fractionation treatment schedule in comparison with conventional fractionation in primary definitive radiotherapy for laryngeal squamous cell carcinoma. From March 1999 to December 2000, a group of 28 patients with previously untreated squamous cell carcinoma of the larynx were irradiated with conventional fractionation to to total doses of 66 to 70 Gy in 33 to 35 fraction/6.5 to 7 weeks, 2 Gy/fraction/day, 5 days/week. From January 2001 to June 2004, the other 27 patients with the same diagnosis, were treated prospectively with hyperfractionation receiving radiotherapy delivered at 1.2 Gy/fraction, twice daily, 5 days/week to 74.4 to 79.2 Gy/62 to fractions/6.2 to 7 weeks. Complete response rates after two mounts of radiotherapy completion were 78.6% (22 of 28) and 66.7% (18 of 27) in the conventional fractionation and hyperfractionation group, respectively (Fisher exact test; P=0.246). The two year loco-regional control rates were 61 .0%±18.1 (95% CI) in the conventional fractionation group and 45.0%±18.8 (95% CI) in the hyperfractionation group (long-rank test; P=0.075). Overall survival rate at two years was 71.0%±16.8 (95% CI) for the conventional group and 43.0%±18.7 (95% CI) for the hyperfractionation group (long- rank test; P=0.071). The absence of statistically significant differences either in loco-regional control or overall survival observed between the two treatment modalities suggested that hyperfractionation regimen was not more efficacious than conventionally fractionated radiotherapy for previously untreated carcinoma of the larynx.

  1. MAML2 rearrangement in primary pulmonary mucoepidermoid carcinoma and the correlation with FLT1 expression.

    Fen Zhu

    Full Text Available INTRODUCTION: Primary pulmonary mucoepidermoid carcinoma (PMEC is an uncommon neoplasm with remarkable resemblance to mucoepidermoid carcinoma of the salivary glands. The latter has been shown to harbor t(11,19 resulting in MECT1-MAML2 fusion, which may be of diagnostic and prognostic values. However, the importance of such feature in PMEC has not been well studied. METHODS: We detected MAML2 rearrangement using fluorescence in situ hybridization (FISH in tissue samples from 42 cases of PMEC and 40 of adenosquamous carcinoma (ASC, and the expression of potential downstream targets of MECT1-MAML2, including HES1, FLT1 and NR4A2 with immunohistochemistry (IHC. The findings were then examined regarding the clinicopathological parameters and patient outcomes. RESULTS: FISH analysis revealed MAML2 rearrangement in 50% of the PMEC cases, and such property was prominent in considerable younger patients (33 versus 60 years; p = 0.001 and restricted to cases of low and intermediate grades. IHC analysis showed that FLT1 and HES1 were expressed at lower level in MAML2 rearranged group than MAML2 non-rearranged group (p<0.001 and p = 0.023, respectively. Survival analysis showed significant correlation between MAML2 rearrangement and overall survival (p = 0.023 or disease-free survival (p = 0.027 as well as correlation between FLT1 and overall survival (p = 0.009. CONCLUSIONS: MAML2 rearrangement appears frequent in PMEC and specific with this tumor. Both the presence of MAML2 rearrangement and absence of FLT1 tend to confer a favorable clinical outcome. These findings suggest that molecular detection of MAML2 rearrangement combined with FLT1 may be of important clinical value for PMEC.

    The purpose of this study was to evaluate treatment results in terms of the survival and failure patterns subsequent to radiation therapy in recurrent cervical cancer, following primary surgery. Between January 1990 and December 1999, 27 patients, with recurrent cervical cancer following primary surgery, were subsequently treated with radiation in the Department of Radiation Oncology, at the Keimyung University Dongsan Medical Center. Their median age was 48, ranging from 31 to 70 years old. With regard to the initial FIGO stage on presentation, 20 and 7 patients were stages I and II, respectively. Twenty three patients had squamous ceH carcinomas and 4 had adenocarcinomas. The time interval from the primary surgery to the recurrence ranged from 2 to 90 months with a median of 29 months. The recurrent sites were the vaginal cuff alone, the pelvic cavity and combined recurrence in 14, 9 and 4 patients, respectively. Radiation was performed, with external and vaginal intracavitary radiation in 13 patients, external radiation alone in 13 and vaginal intracavitary radiation alone in another one. The median follow-up period was 55 months, ranging from 6 to 128 months. The five year disease free survival (5y DFS) and five year overall survival (5y OS) rates were 68.2 and 71.9%, respectively. There was a marginal statistically significant difference in the 5y DFS in relation to the recurrent site (5y DFS, 85.7% in vaginal cuff recurrence alone, 53.3% in pelvic cavity recurrence, p=0.09). There was no difference in the survival according to the time interval between the primary surgery and a recurrence. There was only a 7% local failure rate in the patients with a vaginal cuff recurrence. The major failure patterns were local failure in the patients with pelvic cavity recurrence, and distant failure in the patients with a combined recurrence. There were no complications above grade 3 after the radiation therapy. Radiation therapy was safe and effective treatment for a

    Full Text Available RACIONAL: Metástases podem ser a primeira manifestação de adenocarcinoma. Cerca de 60% destas podem ser cutâneas e correspondem a casos de neoplasia em estágio avançado. A procura pelo sítio primário é onerosa, sendo necessário o emprego de diversos exames de imagem, endoscópicos e imunoistoquímicos. Apesar disto, o sítio primário é descoberto somente em 15% a 20% dos pacientes, sendo os demais casos reconhecidos nas autopsias. OBJETIVO: Relatar um caso de adenocarcinoma, moderadamente diferenciado metastático cutâneo, de sítio primário desconhecido. A região acometida foi a pele da fossa ilíaca esquerda. RESULTADOS: A lesão foi ressecada cirurgicamente. O sítio primário não foi identificado por nenhum exame de imagem ou endoscópico. O estudo imunoistoquímico revelou o seguinte padrão de imunoperoxidase: CEA negativo, CK7 positivo, CK20 negativo e PSA negativo. Com base nestes achados, foram afastados tumores primários do intestino grosso e da próstata (PSA, CK20 e CEA negativos. Os principais sítios primários aventados foram pâncreas e vias biliares. CONCLUSÃO: A procura pelo sítio primário de adenocarcinoma metastático continua sendo tarefa difícil, onerosa e com pouco impacto no tratamento dos pacientes acometidos.BACKGROUND: Metastases may be the first manifestation of adenocarcinoma. Up to 60% are cutaneous and present in advanced stage neoplasms. Research for the primary site is costly and requires endoscopy, imaging and immunohistochemical exams. The primary site becomes obvious in only 15% to 20% of live patients and is detected mainly at autopsy. AIM: To report a case of metastatic cutaneous moderately differentiated adenocarcinoma of unknown primary site, located in the lower left abdomen. RESULTS: The lesion was surgically resected. Primary site was not found by any imaging or endoscopy exams. The immunohistochemistry was negative for CEA, CK20, PSA and positive for CK7. Based on these exams

    Virtually all primary peritoneal carcinomas (PPCs) are of serous papillary type. We report an unusual histologic type of PPC composed of anaplastic giant cells, which exhibited an aggressive clinical course. A 72-year-old woman presented with lower abdominal pain. Computed tomography showed a diffuse omental thickening. The patient underwent an exploratory laparotomy with omentectomy, total hysterectomy, bilateral salpingo-oophorectomy, and appendectomy. Pathologic examination revealed extensive omental replacement by tumor but only superficial surface cortical involvement of both ovaries, a disease distribution consistent with a typical müllerian-derived PPC. However, this neoplasm was composed of diffuse anaplastic tumor giant cells, rather than serous carcinoma, which is the usual histologic type encountered in PPC. The patient died within 1 month after surgery. We report this unusual histologic variant of PPC to raise awareness that anaplastic giant cell carcinoma may arise in the pelvic peritoneum as a primary tumor.

    Peripheral T-cell lymphomas (PTCLs) are aggressive neoplasms which may involve the liver. The imaging manifestations of hepatic lymphoma are highly variable and show overlapping appearances of numerous other hepatic diseases. As the management and prognosis of lymphoma differ markedly from those of other malignant diseases, prompt diagnosis and early effective treatment are very important. Here, we report an atypical case of primary PTCL not otherwise specified involving the liver that exhibited a solitary hepatic mass mimicking hepatocellular carcinoma (HCC) on CT. Liver biopsy is not commonly recommended in highly suspicious cases of HCC. However, in a patient without risk factors for HCC, consideration of other diagnostic possibilities is required and needle biopsy may be a more rational choice. An imaging approach, based on a careful review of clinical and laboratory findings is essential to prevent false-positive diagnosis of HCC and subsequent invasive treatment.

    A pilot trial is currently under way at our institution to determine the potential of new Y-90 glass microspheres (Theraspheres, Theragenics Corp., Atlanta) for the treatment of primary hepatocellular carcinoma. The Y-90 microspheres are injected through a percutaneous hepatic artery catheter positioned angiographically. The injection is facilitated by a new delivery system. Prior to the injection of the Y-90 microspheres, the presence of shunting is assessed by injecting Tc-99m human albumin microspheres (HAM) via the hepatic artery catheter. Bremsstrahlung scans done after injection demonstrate the distribution the Y-90 microspheres within the liver and the lack of extrahepatic activity. In the first group of patients treated, no significant toxicity was demonstrated for absorbed doses between 5,000 and 10,000 rad to the liver, and up to 20,000 rad to the tumor itself

  7. In situ identification of CD44+/CD24- cancer cells in primary human breast carcinomas.

    Giuseppe Perrone

    Full Text Available Breast cancer cells with the CD44+/CD24- phenotype have been reported to be tumourigenic due to their enhanced capacity for cancer development and their self-renewal potential. The identification of human tumourigenic breast cancer cells in surgical samples has recently received increased attention due to the implications for prognosis and treatment, although limitations exist in the interpretation of these studies. To better identify the CD44+/CD24- cells in routine surgical specimens, 56 primary breast carcinoma cases were analysed by immunofluorescence and confocal microscopy, and the results were compared using flow cytometry analysis to correlate the amount and distribution of the CD44+/CD24- population with clinicopathological features. Using these methods, we showed that the breast carcinoma cells displayed four distinct sub-populations based on the expression pattern of CD44 and CD24. The CD44+/CD24- cells were found in 91% of breast tumours and constituted an average of 6.12% (range, 0.11%-21.23% of the tumour. A strong correlation was found between the percentage of CD44+/CD24- cells in primary tumours and distant metastasis development (p = 0.0001; in addition, there was an inverse significant association with ER and PGR status (p = 0.002 and p = 0.001, respectively. No relationship was evident with tumour size (T and regional lymph node (N status, differentiation grade, proliferative index or HER2 status. In a multivariate analysis, the percentage of CD44+/CD24- cancer cells was an independent factor related to metastasis development (p = 0.004. Our results indicate that confocal analysis of fluorescence-labelled breast cancer samples obtained at surgery is a reliable method to identify the CD44+/CD24- tumourigenic cell population, allowing for the stratification of breast cancer patients into two groups with substantially different relapse rates on the basis of CD44+/CD24- cell percentage.

    In Denmark there is an increasing frequency of laryngeal carcinoma, in particular in women and among these especially in supraglottic tumours. The incidence during the past 20 years has risen from about 40 to 60 cases per million per year. A series of 335 consecutive patients treated with primary radiation is presented. In one-third of all patients the tumour was localized in the supraglottic area; in women in more than half and in men in about one-fourth of the cases. The frequency of primary lymph node metastases in the supraglottic and the glottic tumours was 24% and 2% respectively. A multivariate analysis identified sex and tumour size as independent prognostic parameters of local control. Five-year survival corrected for intercurrent deaths was obtained in 59% of all cases, in 56% of supraglottic and in 92% of glottic tumours. A multivariate analysis defined localization, tumour grade and stage as independent prognostic parameters of survival. Salvage surgery was performed in about 32% of the cases, total laryngectomy in 26%, and partial laryngectomy in 6%. The survival rate among all total laryngectomies was 55%. A tracheostomy during or before radiation treatment prior to total laryngectomy had no influence on complication rate, admission time or recurrence rate. The frequency of pharyngo-cutaneous fistulae in the entire series was 11.5%; after routine use of metronidazol, however, only 5.7%. Radical neck dissection was carried out in 7.8% of the cases, by far most in the supraglottic group, only a few in the glottic carcinomas, in three-fourth in connection with a laryngectomy and in one-fourth without local recurrence in the larynx.

    Borderline ovarian tumors (BOTs) represent a heterogeneous group of ovarian epithelial neoplasms. Despite a favorable prognosis, 10-20% of BOTs exhibit progressively worsening clinic. Primary involvement of pelvic organs with echinococcus is very rare. Lymphoepithelioma-like gastric carcinoma is a rare neoplasm of the stomach. A 58-year-old woman referred with abdominal swelling and gastric complaints. Imaging studies revealed a huge cystic mass with multiple septations and solid component, another cystic mass with an appearance of cyst hydatid in the pelvis, and thickening of the small curvature of stomach. Gastroscopy revealed an ulcer with a suspicious malignant appearance, and histology of the endoscopic specimen showed severe chronic inflammation and lymphocytic infiltration. No other involvement of hydatid cyst was detected. In the exploration, there was a 25cm cystic lesion with solid components arising from right ovary, another 6cm cyst over the former, 7cm cystic lesion arising from left ovary, and 10cm mass near the small curvature of the stomach. Excision of the masses; total gastrectomy with esophagojejunal anastomosis; total abdominal hysterectomy; bilateral salpingo-oophorectomy; omentectomy; appendectomy; splenectomy; and pelvic, paraaortic, and coeliac lympadenectomy were performed. Final pathology revealed lymphoepithelioma-like gastric carcinoma, bilateral serous BOT, and hydatid cyst. Hydatid cyst should always be considered in the differential diagnosis of abdominopelvic masses in endemic regions of the world. Preoperative diagnosis of primary pelvic hydatid disease is difficult and awareness of its possibility is very important especially in patients residing in or coming from endemic areas.

    Purpose: The purpose was to evaluate the contralateral nodal control (CLNC) in postoperative patients with oral and oropharyngeal cancer treated with ipsilateral irradiation of the neck and primary site. Late radiation-induced morbidity was also evaluated. Methods and Materials: The study included 123 patients with well-lateralized squamous cell carcinomas treated with surgery and unilateral postoperative irradiation. Most patients had tumors of the gingiva (41%) or buccal mucosa (21%). The majority of patients underwent surgery of the ipsilateral neck (n = 102 [83%]). The N classification was N0 in 73 cases (59%), N1 or N2a in 23 (19%), and N2b in 27 cases (22%). Results: Contralateral metastases developed in 7 patients (6%). The 5-year actuarial CLNC was 92%. The number of lymph node metastases was the only significant prognostic factor with regard to CLNC. The 5-year CLNC was 99% in N0 cases, 88% in N1 or N2a cases, and 73% in N2b cases (p = 0.008). Borderline significance (p = 0.06) was found for extranodal spread. Successful salvage could be performed in 71% of patients with contralateral metastases. The prevalence of Grade 2 or higher xerostomia was 2.6% at 5 years. Conclusions: Selected patients with oral or oropharyngeal carcinoma treated with primary surgery and postoperative ipsilateral radiotherapy have a very high CLNC with a high probability of successful salvage in case of contralateral metastases. However, bilateral irradiation should be applied in case of multiple lymph node metastases in the ipsilateral neck, particularly in the presence of extranodal spread. The incidence of radiation-induced morbidity is considerably lower as observed after bilateral irradiation.

    MTT staining procedures have been used in chemosensitivity testing of established cell lines of human and other sources as well as of human leukaemias, but only limited information on its application in primary solid human tumors is presently available. We have evaluated MTT staining in primary human Renal Cell Carcinomas (RCCs), studied various factors interfering with the optimal use, and finally applied it in subsequent chemosensitivity testing. The method depends on the conversion of a water-soluble tetrazolium salt (MTT) to a purple colored formazan precipitate, a reaction effected by enzymes active only in living cells. Single cell suspensions of RCCs were obtained either by enzymatic dispersion or by mechanical dissagregation, filtered through gauze, and purified by Ficoll density centrifugation. Tests were carried out in 96-well microculture plates. 10(4) viable tumor cells per well at 4 h incubation time with 20 micrograms MTT/100 microliters total medium volume yielded best results. Formazan crystals were dissolved with DMSO, and the plates were immediately measured on a microculture plate reader at 540 nm. Under these criteria, linearity of the system could be demonstrated. For chemosensitivity testing, cells were continuously exposed to a number of drugs prior to the MTT staining procedure. Reproducibility of results was assessed and confirmed by culturing RCCs in flasks additionally, resubmitting them after 1, 2, and 4 weeks to the MTT assay. We conclude that the semiautomated MTT assay offers a valid, rapid, reliable and simple method to determine the degree of chemoresistance in primary human RCCs.

    Full text: To explore the clinical value of PET/CT scanning in search of the primary carcinoma, we selected 4 patients who were subjected to PET/CT examination during Oct. 2002 to Dec. 2002. The primary lesion in all these patients was not detected. One of them had metastasis to liver, one had metastases in both lungs and the other two were having metastases to the bones. 18F-FDG in doses of 5.55MBq / kg body weight was injected to a fasting patient (at least 6 hours). PET/CT whole body examination was done using Discovery LS-PET/CT (GE Medical System, U.S.A.) 40-60 minutes later. In the first patient with metastasis to liver, primary lesion was localized in the transverse colon near the liver. The PET/CT showed multiple high radioactive uptake lesions of different sizes in the liver. No obvious change in position of the colon uptake was seen on the delayed images. After PET/CT, barium examination showed thinned cavity of the colon near the liver with coarse ankylosis of colon wall just like saw tooth. The mucous membrane was destroyed. Of the two patients with metastases in the bone, first - a 31 years old, was diagnosed to have primary lung cancer with multiple metastases to the liver and the bones. PET/CT showed high radioactive uptake in the inferior left lobe near the hilum with irregular shaped uneven distribution. A round high radioactive uptake area of 1.82 x 1.84 x 1.46cm size was also seen in the right lobe of the liver having clear edge and uneven distribution. The destroyed bones (L-10, L-11, L-12, T-1 and ala ossis i lii) showed high radioactive uptake. Second patient, 57-year male was diagnosed to have malignant lymphoma. PET/CT fusion showed high radioactive uptake in the marrow of whole body. Few destroyed parts of bones were also seen on CT images. Several cervical and the thoracic vertebrae as well as the ninth rib showed irregular radioactive accumulation with clear edges and well-distributed tracer raising the possibility of multiple myeloma or

    Objective: To evaluate the usefullness of flexible esophagoscopy and chromoendoscopy with Lugol's solution in the detection of synchronous esophageal neoplasm in patients with hypopharyngeal squamous cell carcinoma (HSCC). Methods: A retrospective review of 96 cases with HSCC that received surgical treatment from March 2016 to March 2017 was accomplished. In these patients, the site of origin were pyriform sinus ( n =75), posterior pharyngeal wall ( n =11) and postcricoid ( n =10). Esophagoscopy was prospectively performed on all patients before treatment for HSCC. All patients underwent conventional white-light endoscopic examination with Lugol chromoendoscopy and narrow band image. Suspicious areas of narrow band image or Lugol-voiding lesions were observed and biopsied. The treatment strategy of primary HSCC was modified according to the presence of synchronous esophageal squamous cell neoplasms by a multidisciplinary approach. Results: Ninety-six patients were enrolled (age ranging from 37-80 years). All patients did not have previous treatment.Histopathological analysis revealed middle to high-grade dysplasia in 5 cases, Tis cancer in 5 cases, cancer in 16 cases and inflammation or normal findings in the others. Four cases were treated with endoscopic submucosal dissection before hypopharygeal surgery, 3 cases with lower esophageal cancers were treated with gastric pull-up combined with free jejunal flap after total circumferential pharyngolaryngectomy (TCPL) and certical esophagectomy, and 14 cases were treated with TCPL, total esophagectomy and gastric pull-up. Conclusions: Esophagoscopy is a feasible and justified procedure in HSCC cases as it enhances the detection of premalignant lesion or second primary cancer. Routine esophagoscopy for detecting synchronous second primary tumor should be recommended for patients with HSCC. The treatment strategy for primary HSCC is modified according to the presence of synchronous second primary tumor.

    Primary squamous cell carcinoma of the breast is a very rare tumor accounting for less than 0.4% of all breast cancers. Fewer than 100 cases have been reported in the literature so far. The diagnosis requires strict pathologic criteria to be fulfilled. Due to the rarity of this tumor the optimal treatment and prognosis are both unclear. Breast abscess as the initial presentation of a primary squamous cell breast carcinoma is an extremely rare clinical entity. In this study, we describe a case of a 61-year-old postmenopausal woman who presented with typical manifestations of a breast abscess and was diagnosed with a pure primary squamous cell breast carcinoma. Diagnostic evaluation and management of the patient are discussed along with a review of the literature. Despite its rarity, the possibility of a primary pure squamous cell breast carcinoma should always be considered in the differential diagnosis in postmenopausal patients presenting with manifestations of a breast abscess, especially in those who respond poorly to the initial treatment. Physicians should be aware of this rare malignancy in order to avoid delays in diagnosis and treatment.

    First of all, this study was performed to assess the result of curative radiotherapy and to evaluate different possible prognostic factors for squamous cell carcinoma of the supraglottic larynx treated at the Pusan National University Hospital. The second goal of this study was by comparing our data with those of other study groups, to determine the better treatment policy of supraglottic cancer in future. Thirty-two patients with squamous cell carcinoma of the supraglottic larynx were treated with radiotherapy at Pusan National University Hospital, from August 1985 to December 1996. Minimum follow-up period was 29 months. Twenty-seven patients (84.4%.) were followed up over 5 years. Radiotherapy was delivered with 6 MV photons to the primary laryngeal tumor and regional lymphatics with shrinking field technique. All patients received radiotherapy under conventional fractionated schedule (once a. day). Median total tumor dose was 70.2 Gy (range, 55.8 to 75.6 Gy) on primary or gross tumor lesion. Thirteen patients had induction chemotherapy with cisplatin and 5-fluorouracil (1-3 cycles). Patient distribution, according to the different stages, were as follows: stage I, 5/32 (15.6%); stage II, 10/32 (31.3%); stage III, 8/32 (25%); stage IV, 9/32 (28. 1 %). The 5-year overall survival rate of the whole series (32 patients) was 51.7%. The overall survival rate at 5-years was 80% in stage I, 66.7% in stage II, 42.9% in stage III, 25% in stage IV.(p= 0,0958). The 5-year local control rates after radiotherapy were as follows: stage I, 100%; stage II, 60%; stage III, 62.5%; stage lV, 44.4% (p=0.233). Overall vocal preservation rates was 65.6%,100% in stage I, 70% in stage II, 62.5% in stage III, 44.4% in stage IV (p=0.210). There was no statistical significance in survival and local control rate between neoadjuvant chemotherapy followed by radiotherapy group and radiotherapy alone group. Severe laryngeal edema was found in 2 cases after radiotherapy. emergent tracheostomy

    Purpose: To determine whether findings on CT studies, done 6 weeks after radiotherapy (RT), can predict the likelihood of ultimate control at the primary site in oropharyngeal carcinoma. Methods and Materials: Forty-six patients with oropharyngeal squamous cell carcinoma underwent RT with curative intent. A minimal 2-year clinical follow-up after RT was required. The primary site CT findings were graded for risk of recurrence on a modified 3-point scale as follows: Grade 0, no detectable focal abnormalities; Grade 1, anatomic asymmetry or focal mass 10 mm (2a) or 10 mm at the primary site, the likelihood of local control is high (93%). The study results indicate that CT findings, based on this relatively small series, may not add incremental information beyond that of clinical examination for predicting local control but may be useful as a baseline if imaging surveillance is contemplated

    Full Text Available Abstract: We present a rare case of extraovarian primary peritoneal carcinoma in 65-year-old female with a history of total abdominal hysterectomy and bilateral salpingo-oophorectomy for larger symptomatic leiomyoma 13 years ago. In October 2005 the patient had abdominal swelling, ascites with positive cytology peritonal adenocarcinoma and significantly elevated serum Ca-125 was 500 U/ml. Clinical examinations were performed, but could not identify a unique origin of disease. Background: Aproximatly 3.2 % to 21 % of extraovarian primary peritoneal carcinoma patients have a history bilateral oophorectomy for benign disease or prophylaxis – family history of ovar- ian carcinoma.1 Patients and methods: A 65-year old woman with a history of total abdominal hysterectomy and bileteral salpin- go-oophorectomy was operated for larger symptomatic leiomyoma 13 years ago. In Octobre 2005 the patient had abdominal swelling, ascites with positive cytology peritonal adeno- carcinoma and significantly elevated serum Ca-125 was 500 U/ml. Radiologic imaging, gastroscopy, colonoscopy, mammography were performed, but couldn`t identify a unique origin of disease. Patient was treated for two years at the Oncology Institute Ljubljana. Significantly elevated serum Ca-125 and citology with immunohistochemical analysis pre- sented correct diagnosis of extraovarian primary peritoneal carcinoma. The patient was treated with combination systemic chemotherapy (Paclitaxel and Carboplatin with initial good response. In year 2006 and 2007 because of the progression of disease, the treatment was repeated with adjuvant chemotherapy. Conclusions: Look like in other similar cases we have confirmed our disease with three cytologic punction procedures, with significant elevated valves of Ca-125 and with several other directed proce- dures.1–3 Our patient has survived the characteristic critical period for this form of cancer of 7 to 27.8 months because of well orientated

    To test the performance of sequential {sup 18}F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) in predicting survival after sunitinib therapies in patients with cancer of unknown primary (CUP). CUP patients were enrolled for sequential PET/CT scanning for sunitinib and a control group. Univariate and multivariate analysis were applied to test the efficacy of sunitinib therapy in CUP patients. Next, sequential analyses involving PET/CT parameters were performed to identify and validate sensitive PET/CT biomarkers for sunitinib therapy. Finally, time-dependent receiver operating characteristic (TDROC) analyses were performed to compare the predictive accuracy. Multivariate analysis proved that sunitinib group had significantly improved survival (p < 0.01) as compared to control group. After cycle 2 of therapy, multivariate analysis identified volume-based PET/CT parameters as sensitive biomarkers for sunitinib (p < 0.01). TDROC curves demonstrated whole-body total lesion glycolysis reduction (Δ WTLG) and follow-up WTLG to have good accuracy for efficacy prediction. This evidence was validated after cycle 4 of therapy with the same method. Sunitinib therapy proved effective in treatment of CUP. PET/CT volume-based parameters may help predict outcome of sunitinib therapy, in which Δ WTLG and follow-up WTLG seem to be sensitive biomarkers for sunitinib efficacy. Patients with greater reduction and lower WTLG at follow-up seem to have better survival outcome. (orig.)

    OBJECTIVES: Changes, over the last 20 years, in the diagnostic procedures and treatment of primary liver cancer (PLC) and liver metastases of unknown origin (LMUO) may have affected the clinical course of both cancers. Few longitudinal studies examined this issue. In a population-based setting, we...... studied changes in the incidence and prognosis of PLC and LMUO over time. METHODS: Between 1985 and 2004, we identified 2675 patients with PLC and LMUO in three Danish counties, with a population of 1.4 million. We computed the standardized incidence rate (SIR), ratio of PLC to LMUO diagnoses, median...... survival, and estimated mortality rate ratio adjusted for age, sex, and comorbidity. RESULTS: The SIR of PLC increased from 3.2 in 1985 to 5.0 in 2003, and the SIR of LMUO increased from 3.7 to 6.4. No increase was noted in the PLC-to-LMUO ratio over time (P=0.1 for trend). From 1985 to 2004, the median...

    Background and purpose: In this prospective study, the effect of a second course of primary radiotherapy on locoregional control, survival and toxicity was investigated, in patients who underwent a second course of high dose irradiation for second primary or locoregional recurrent squamous cell head and neck carcinoma (HNSCC) in a previously irradiated area. Patients and methods: A total of 34 patients with second primary (n=26) or locoregional recurrent (n=8) tumours were treated with a second course of high dose radiotherapy. Patients were selected for re-irradiation in case of inoperable and/or unresectable tumours. In most cases, the target volume for re-irradiation was confined to the gross tumour volume (GTV). No elective radiotherapy was applied in the former high-dose area. A total dose of 46 Gy was applied to elective areas with a boost up to 60 Gy with conventional fractionation. The median follow-up period was 32 months. Results: The locoregional control rate after 2 years was 27%. The 3-year overall survival was 22%. The most frequently reported acute side-effect was acute mucositis resulting in swallowing complaints. Pharyngeal and oesophageal late morbidity was also the most important late side-effect. In general, acute and late radiation-induced morbidity remained within acceptable limits. Conclusions: In conclusion, primary re-irradiation appears to be feasible in terms of acute and late radiation-induced toxicity. To improve outcome in terms locoregional control and survival, future studies should be focussed on optimising radiation schedules and the addition of concomitant chemotherapy

    Purpose: To evaluate the significant prognosticators in nasopharyngeal carcinoma (NPC). Methods and Materials: From 1984 to 1989, 903 treatment-naive nondisseminated (MO) NPC were given primary radical radiotherapy to 60-62.5 Gy in 6 weeks. All patients had computed tomographic (CT) and endoscopic evaluation of the primary tumor. Potentially significant parameters (the patient's age and sex, the anatomical structures infiltrated by the primary lesion, the cervical nodal characteristics, the tumor histological subtypes, and various treatment variables were analyzed by both monovariate and multivariate methods for each of the five clinical endpoints: actuarial survival, disease-free survival, free from distant metastasis, free from local failure, and free from regional failure. Results: The significant prognosticators predicting for an increased risk of distant metastases and poorer survival included male sex, skull base and cranial nerve(s) involvement, advanced Ho's N level, and presence of fixed or partially fixed nodes or nodes contralateral to the side of the bulk of the nasopharyngeal primary. Advanced patient age led to significantly worse survival and poorer local tumor control. Local and regional failures were both increased by tumor infiltrating the skull base and/or the cranial nerves. In addition, regional failure was increased significantly by advancing Ho's N level. Parapharyngeal tumor involvement was the strongest independent prognosticator that determined distant metastasis and survival rates in the absence of the overriding prognosticators of skull base infiltration, cranial nerve(s) palsy, and cervical nodal metastasis. Conclusions: The significant prognosticators are delineated after the advent of CT and these should form the foundation of the modern stage classification for NPC

    Despite advances in therapeutics, outcomes for hepatocellular carcinoma (HCC) remain poor and there is an urgent need for efficacious systemic therapy. Unfortunately, drugs that are successful in preclinical studies often fail in the clinical setting, and we hypothesize that this is due to functional differences between primary tumors and commonly used preclinical models. In this study, we attempt to answer this question by comparing tumor morphology and gene expression profiles between primary tumors, xenografts and HCC cell lines. Hep G2 cell lines and tumor cells from patient tumor explants were subcutaneously (ectopically) injected into the flank and orthotopically into liver parenchyma of Mus Musculus SCID mice. The mice were euthanized after two weeks. RNA was extracted from the tumors, and gene expression profiling was performed using the Gene Chip Human Genome U133 Plus 2.0. Principal component analyses (PCA) and construction of dendrograms were conducted using Partek genomics suite. PCA showed that the commonly used HepG2 cell line model and its xenograft counterparts were vastly different from all fresh primary tumors. Expression profiles of primary tumors were also significantly divergent from their counterpart patient-derived xenograft (PDX) models, regardless of the site of implantation. Xenografts from the same primary tumors were more likely to cluster together regardless of site of implantation, although heat maps showed distinct differences in gene expression profiles between orthotopic and ectopic models. The data presented here challenges the utility of routinely used preclinical models. Models using HepG2 were vastly different from primary tumors and PDXs, suggesting that this is not clinically representative. Surprisingly, site of implantation (orthotopic versus ectopic) resulted in limited impact on gene expression profiles, and in both scenarios xenografts differed significantly from the original primary tumors, challenging the long

    We present here the case report of a postmenopausal woman who complained of recurrent pus-like vaginal discharge and perianal pain 1 year after Le Fort colpocleisis, which was subsequently identified as a primary invasive carcinoma of the vagina. Biopsy confirmed a squamous cell carcinoma in the vagina, and the disease was classified as stage III according to FIGO staging. The patient received pelvic radiotherapy. This case emphasizes that differential diagnosis of recurrent vaginal discharge that presents remote from obliterative procedure for pelvic organ prolapse should consider not only pyometra, but also other causes.

    AIM: To review the surgical outcomes in terms of the surgical indications and relevant prognostic factors. METHODS: Sixteen patients underwent therapeutic lung surgery between March 1999 and May 2006. The observation period was terminated on May 31, 2007. The surgical outcomes and the clinicopathological factors were compared. RESULTS: There was no mortality or major morbidity encountered in this study. The mean follow-up period after metastasectomy was 26.7 ± 28.2 (range: 1-99 mo), and the median survival time was 20 mo. The 1- and 5-year survival rates were 56% and 26%, respectively. At the end of the follow-up, 1 patient died from hepatic failure without recurrence, 6 died from hepatic failure with a recurrent hepatocellular carcinoma (HCC), and 4 died from recurrent HCC with cachexia. Among several clinical factors, Kaplan-Meier analysis revealed that liver transplantation as a treatment for the primary lesion, grade of cell differentiation, and negative evidence HBV infection were independent predictive factors. On Cox’s proportional hazard model, there were no significant factors affecting survival after pulmonary metastasectomy in patients with HCC. CONCLUSION: A metastasectomy should be performed before other treatments in selected patients. Although not significant, patients with liver transplantation of a primary HCC survived longer. Liver transplantation might be the most beneficial modality that can offer patients better survival. A multi-institutional and collaborative study would be needed for identifying clinical prognostic factors predicting survival in patients with HCC and lung metastasis. PMID:18837090

    The incidence of renal cell carcinoma (RCC) and metastatic adrenal lesions continues to rise and present evolving complexities in terms of management. Technical challenges in treatment delivery are compounded by the setting of an ageing patient population with multiple medical co-morbidities. While the standard of care treatment for both primary RCC and oligometastatic adrenal lesions has typically been surgery, a number of patients may be medically or surgically inoperable, and for whom alternative options require consideration. Additionally, in metastatic disease, surgery presents an invasive option, sometimes with unacceptable risks of perioperative morbidity and therefore is considered a less desirable option to some. Stereotactic body radiotherapy (SBRT) is an established radiotherapy technique that is rapidly being incorporated into many radiotherapy departments, particu-larly with the increasing availability and capabilities of modern linear accelerators to deliver precise image guided treatment. There are considerable advantages of SBRT including its ability to provide a non-invasive ablative treatment with very few treatment sessions, with emerging evidence showing promising rates of local control (LC) and low associated mor-bidity. This review details the use of SBRT for primary RCC as well as adrenal metastases, focusing on issues including patient selection, technical considerations, and patient out-comes. Furthermore, this review explores some recent insights into the radiobiology of RCC, the immunomodulatory effects of SBRT, and the use of systemic agents with SBRT.

    Primary carcinoma of the fallopian tube is a very unusual gynecologic malignancy that accounts for less than 1% of all malignancies of the female genitalia. A 55-year-old, gravida 7, para 3 woman presented with no gynecologic complaints other than backache. TVS demonstrated a 35 x 25 mm heterogeneous mass that was not clearly separated from the left ovary, and another 31 x 14 mm cystic septated lesion in the left ovary region. Pelvic MRI demonstrated a 35 x 35 x 20 mm left adnexal mass that enhanced with contrast and a neighboring tubular-cystic mass. Upper and lower gastrointestinal endoscopy revealed no malignancy. Serum CA 125-level was merkedly elevated at 369 U/ml (normal serous adenocarcinoma. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, appendectomy, omentectomy, pelvic and para-aortic lymph node dissection, and peritoneal washing were performed. The definitive histopathological diagnosis was primary serous adenocarcinoma of the fallopian tube with six of 25 lymph node biopsies showing metastasis. Six cycles of paclitaxel (175 mg/m2) plus cisplatin (75 mg/m2) combinatin chemotherapy were administered with 3-week intervals between cycles. Second-look laparotomy was performed; there was no evidence of disease. At the time of writing 12 months after the second-look laparotomy, she was still disease-free.

    To compare the prognosis of patients with advanced-stage primary peritoneal serous papillary carcinoma (PSPC) or papillary serous ovarian cancer (PSOC). This was a retrospective case-control study and included two study groups: one with stage III/IV PSPC (n = 38) patients and the other with PSOC (n = 53) patients. Patients were matched for histologic subtype (serous tumor), tumor stage, tumor grade, residual disease at the end of debulking surgery (primary or interval), and age (±5 years). Mean age was significantly greater for patients with PSPC (63.03 ± 11.88 years) than for patients with PSOC (55.92 ± 12.56 years, p = 0.008). Optimal debulking surgery was performed initially in 71.9% of PSPC patients and 66.0% of PSOC patients. In addition, 93.9% of PSPC patients and 92.3% of PSOC patients were treated with platinum-paclitaxel chemotherapy. The frequency of high-grade tumors was significantly higher in the PSPC (100%) than in the PSOC group (68.3%; p statistic). PFS was similar for advanced-stage PSPC and PSOC patients. Since the PSPC patients tended to be older and have more high-grade tumors, OS was shorter for PSPC than for POSC patients. Thus, management of the two types of cancer should not differ.

    Objective: To investigate the diagnostic value of combined detection of four tumor markers in patients with possible malignant change in liver disorders. Methods: Serum AFP, CEA, CA199 and SF levels were determined with chemiluminescence immunoassay (CLIA) in 49 patients with primary liver carcinoma, 7 patients with metastatic liver carcinoma, 40 patients with hepatic cirrhosis, 47 patients with HBV hepatitis and 30 controls. Results: The serum levels of AFP, CEA, SF in patients with primary hepatic cancer and serum levels of AFP, SF in patients with hepatic cirrhosis were all significantly higher than those in controls (P 0.05). Moreover, positive rate of combined determination of AFP, CEA, CA199, SF in patients with primary hepatic cancer was significantly higher than that in patients with metastatic liver cancer. Conclusion: With combined determination of these four tumor markers, the detection rate of primary hepatic carcinoma could be enhanced to above 95%. Also, differential diagnosis between primary and metastatic hepatic cancers could be facilitated. (authors)

    Clear cell renal cell carcinoma (ccRCC) is characterized by recurrent copy number alterations (CNAs) and loss of heterozygosity (LOH), which may have potential diagnostic and prognostic applications. Here, we explored whether ccRCC primary cultures, established from surgical tumor specimens, maintain the DNA profile of parental tumor tissues allowing a more confident CNAs and LOH discrimination with respect to the original tissues. We established a collection of 9 phenotypically well-characterized ccRCC primary cell cultures. Using the Affymetrix SNP array technology, we performed the genome-wide copy number (CN) profiling of both cultures and corresponding tumor tissues. Global concordance for each culture/tissue pair was assayed evaluating the correlations between whole-genome CN profiles and SNP allelic calls. CN analysis was performed using the two CNAG v3.0 and Partek software, and comparing results returned by two different algorithms (Hidden Markov Model and Genomic Segmentation). A very good overlap between the CNAs of each culture and corresponding tissue was observed. The finding, reinforced by high whole-genome CN correlations and SNP call concordances, provided evidence that each culture was derived from its corresponding tissue and maintained the genomic alterations of parental tumor. In addition, primary culture DNA profile remained stable for at least 3 weeks, till to third passage. These cultures showed a greater cell homogeneity and enrichment in tumor component than original tissues, thus enabling a better discrimination of CNAs and LOH. Especially for hemizygous deletions, primary cultures presented more evident CN losses, typically accompanied by LOH; differently, in original tissues the intensity of these deletions was weaken by normal cell contamination and LOH calls were missed. ccRCC primary cultures are a reliable in vitro model, well-reproducing original tumor genetics and phenotype, potentially useful for future functional approaches

    Primary epithelial myoepithelial carcinoma of lung is a rare entity and is thought to arise from the submucosal bronchial glands distributed throughout the lower respiratory tract. Because of the rarity of this tumor, we describe one case of epithelial myoepithelial carcinoma arising in the bronchus intermedius and presenting as an endobronchial mass. A 57-year-old male patient presented with an incidental finding of an endobronchial mass located in the lumen of the right lower lobe bronchus and caused near total luminal occlusion of the bronchus. An endobronchial carcinoid tumor was entertained clinically. Subsequently the patient underwent an uneventful videothoracoscopic lobectomy of lower and middle lobes of the right lung. Morphologically and immunohistochemically the tumor was characterized by two cell populations with epithelial and myoepithelial cells forming duct-like structure. The final diagnosis of epithelial myoepithelial carcinoma of lung was rendered.

    AIM: To provide an update on the aetiology, pathogenesis, diagnosis, staging and management of rectal squamous cell carcinoma (SCC). METHODS: A systematic review was conducted according to the preferred reporting items for Systematic Reviews and Meta-Analyses guidelines. A comprehensive search of Ovid MEDLINE was performed with the reference list of selected articles reviewed to ensure all relevant publications were captured. The search strategy was limited to the English language, spanning from 1946 to 2015. A qualitative analysis was undertaken examining patient demographics, clinical presentation, diagnosis, staging, treatment and outcome. The quantitaive analysis was limited to data extracted on treatment and outcomes including radiological, clinical and pathological complete response where available. The narrative and quantitative review were synthesised in concert. RESULTS: The search identified 487 articles in total with 79 included in the qualitative review. The quantitative analysis involved 63 articles, consisting of 43 case reports and 20 case series with a total of 142 individual cases. The underlying pathogenesis of rectal SCC while unclear, continues to be defined, with increasing evidence of a metaplasia-dysplasia-carcinoma sequence and a possible role for human papilloma virus in this progression. The presentation is similar to rectal adenocarcinoma, with a diagnosis confirmed by endoscopic biopsy. Many presumed rectal SCC’s are in fact an extension of an anal SCC, and cytokeratin markers are a useful adjunct in this distinction. Staging is most accurately reflected by the tumour-node-metastasis classification for rectal adenocarcinoma. It involves examining locoregional disease by way of magnetic resonance imaging and/or endorectal ultrasound, with systemic spread excluded by way of computed tomography. Positron emission tomography is integral in the workup to exclude an external site of primary SCC with metastasis to the rectum. While the

    Purpose: To determine quality of life functional outcome after primary radiotherapy for carcinoma of the base of tongue. Methods and Materials: At the University of Florida, essentially all patients with squamous cell carcinoma of the base of tongue are treated with primary continuous-course, external-beam radiotherapy alone or followed by a neck dissection. Fifty-three patients who remained continuously free of disease at 2 to 23 years were eligible to participate in an assessment of the posttreatment quality of their lives. Three patients could not be located for quality of life assessment, and one patient refused to participate, leaving 49 evaluable patients. Radiotherapy doses were 60 to 75 Gy in once daily fractions, or 74 to 79 Gy in twice daily fractions. The subjective Performance Status Scale for Head and Neck Cancer, which assigns a functional score ranging from 0 to 100, was completed by each of the patients during routine follow-up appointments. The scale measures ability to eat in public, understandability of speech, and normalcy of diet. Results: Patients treated with external-beam radiotherapy alone had excellent results with regard to eating in public, though scores showed a decline as T stage increased (average scores were T1: 90.6%; T2: 88.1%; T3: 82.8%; T4: 75.0%). Results for understandability of speech were T1: 93.75%; T2: 100%; T3: 82.8%; and T4: 87.5%. Fixation of the tongue at diagnosis was not a predictor of poor function. Normalcy of diet scores likewise decreased with increasing T stage: T1: 93.8%; T2: 89.5%; T3: 71.3%; T4: 60.0%. The addition of a neck dissection had no impact on the functional outcomes that were evaluated. Functional results did not deteriorate with prolonged follow-up of more than 5 years. Results were compared with those from the literature for patients treated by surgery plus postoperative radiotherapy or external-beam irradiation plus interstitial 192 Ir implant. The functional results of high-dose external

    The development of accessory breast tissue, which is found anywhere along the milk line, is attributed to the failure of milk line remnants to regress during embryogenesis. Primary tumors may arise from any ectopic breast tissue. Accessory breast cancer occurring concurrently with primary invasive breast cancer is extremely rare. Two such cases were reported in this article. One was a 43-year-old Chinese female who exhibited bilateral breast cancer (invasive ductal carcinoma, not otherwise specified, IDC-NOS) and an accessory breast carcinoma (IDC-NOS) incidentally identified in her left axilla. The ectopic breast tissue in her right axilla presented with adenosis. The patient was surgically treated, followed by postoperative docetaxel epirubicin (TE) chemotherapy. The second case was a 53-year-old Chinese female with bilateral breast cancer (apocrine carcinoma) accompanied by an accessory breast carcinoma (IDC-NOS) in her right axilla that was also incidentally identified. The patient was surgically treated after three doses of cyclophosphamide epirubicin docetaxel (CET) neoadjuvant chemotherapy, followed by adjuvant chemotherapy of the same regimen

    The results of Thallium-201(Tl-201) per-rectal scintigraphy in 10 patients with primary hepatocellular carcinoma(HCC) were presented with other clinical findings of contrast hepatic angiography, computed tomography and ultrasonography. Tl-201 accumulation within the tumor was seen in 7 of 10 patients. This accumulation was thought to be due to Tl-201 supply not from the portal vein but from the hepatic artery since significant high heart to liver uptake ratio(H/L) from 0.71 to 1.21(mean 0.95) was observed. Clear visualization of the heart and kidneys indicated the presence of abundant portal-to-systemic shunting. Other 3 patients showed negative Tl-201 accumulation within the tumor and near-normal H/L from 0.32 to 0.47(mean 0.37)which indicates a little portal-to-systemic shunting. This finding reveals the evidence of the lack of Tl-201 supply to the tumor from the portal vein. The results support the idea that HCC does not receive any significant amount of blood flow from the portal system.

    A 69-year-old male smoker was referred to 18F-fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET/CT) with the indication of a suspicious solitary pulmonary nodule. FDG PET/CT determined a 2.5 × 2-cm soft-tissue lesion (SUV{sub ma{sub x}}, 16.2) with spiculated margins in the hilum of the right lung. A 1-cm diameter lymphadenopathy on the right hilum with an SUV{sub max} of 3.2 was also determined. Transbronchial biopsy of the right hilar lymphadenopathy did not reveal any malignant features in histopathologic examination, and it was determined to be reactive. The patient underwent a right upper lobe segmentectomy, and the histopathologic evaluation revealed that the tumor was a primary lymphoepithelioma-like carcinoma (LELC) of the lung with negative Epstein-Barr virus (EBV) on in situ hybridization studies. In this case report, we mainly focus on the FDG avidity of this very rare kind of tumor comparatively with previous reports and possible explanations of discordancy in FDG avidity in relation to histopathologic characteristics.

    Full Text Available Background. The study aims to analyze in detail the incidence, mortality using the standardized incidence ratio (SIR, and standardized mortality ratio (SMR of hepatocellular carcinoma (HCC in primary biliary cirrhosis (PBC, because no large case studies have focused on the detailed statistical analysis of them in Asia. Methods. The study cohorts were consecutively diagnosed at Gunma University and its affiliated hospitals. Age- or sex-specific annual cancer incidence and deaths were obtained from Japanese Cancer Registry and Death Registry as a reference for the comparison of SIR or SMR of HCC. Moreover, univariate analyses and multivariate analyses were performed to clarify predictive factors for the incidence of HCC. Results. The overall 179 patients were followed up for a median of 97 months. HCC had developed in 13 cases. SIR for HCC was 11.6 (95% confidence interval (CI, 6.2–19.8 and SMR for HCC was 11.2 (95% CI, 5.4–20.6 in overall patients. The serum albumin levels were a predictive factor for the incidence of HCC in overall patients. Conclusions. The incidence and mortality of HCC in PBC patients were significantly higher than those in Japanese general population. PBC patients with low serum albumin levels were populations at high risk for HCC.

    Primary non-Hodgkin's lymphoma (LY) and anaplastic carcinoma (AC) of the thyroid gland are rare malignant tumors, and the initial symptoms of these diseases are very similar. The aim of our study was to compare the characteristics of the two diseases using computed tomographic (CT) scans in order to make an accurate differential diagnosis. Ten patients with LY and 10 with AC were analyzed. Differences in the CT findings of the two diseases were evaluated before treatment and statistically tested with either Student's t-test or the chi-square test. In the analysis of characteristics of CT imaging, the existence of calcification and necrosis, and heterogeneous tumor were dominant findings in AC, and there was a statistically significant difference in frequency between the two diseases (p<0.01). Calcification detected in AC was usually multiple and/or gross (mean size: φ8.2 mm). All lymphadenopathies were delineated as having the same homogeneous attenuation as the tumors in the thyroid gland in LY, but were shown as irregular rim enhancement in AC. The CT features of the two diseases are characteristic in terms of calcification, necrosis, and tumor composition. Evaluation by means of CT imaging is useful in distinguishing between LY and AC.

    Primary esophageal small cell carcinoma (SmCC) is a rare disease with a poor prognosis despite agressive multimodality combination treatment. This article presents the case of a 76-year old women diagnosed with pimary esophageal SmCC. The diagnosis was established by upper gastrointestinal endoscopy with biopsies that confirmed an esophageal SmCC positive to synaptophysin, chromogranin, CD56, TTF-1, and cytokeratin 8/18. Further staging procedures included CT, PET and EUS, followed by combination chemotherapy and radiotherapy. Restaging was then performed, again with PET and CT of the thorax, abdomen and pelvis. This was then followed by salvage esophagectomy due to the presence of residual tumor. Surgical pathology confirmed a 3 cm SmCC, with invasion of the submucosa and lymphovascular invasion. In conclusion, the article describes the rare occurrence of esophageal SmCC, together with the algorithm of diagnosis and staging based on state-of-the-art imaging methods. This was followed by combination chemoradiotherapy and surgical esophagectomy as the standard of care in this aggressive disease.

    Purpose: Primary cutaneous neuroendocrine (Merkel cell) carcinoma is a rare neoplasm with aggressive behavior but potential for response to radiotherapy and chemotherapy. Optimal treatment regimens are evolving based on reports of case series and a growing understanding of the natural history. Methods and Materials: A retrospective analysis of 34 cases treated at two Australian Institutions over 13 years is presented, focusing on clinical features and response to therapy. Results: The aggressive nature of this neoplasm is confirmed by the local recurrence rate of 22% following surgical excision, the development of regional node metastases in 76%, and of distant metastases in 70%. Overall median survival was 24 months with 65% of patients succumbing to metastatic disease. An association with B cell malignancies and immunosuppressive therapy is noted, with these patients having a poorer outcome, and one spontaneous remission was observed. Radiation therapy produced responses in 21 of 30 measurable sites (11 complete, 10 partial), and in 11 sites irradiated prophylactically there was only one infield relapse (9%). Responses to chemotherapy were observed in 8 of 20 applications (40%), particularly carboplatin and etoposide given in the setting of regional node disease. Conclusion: In this poor prognosis tumor, further investigation of adjuvant radiotherapy and chemotherapy is warranted, as responsiveness of recurrent disease is confirmed. Immunological factors appear important in the natural history, and their manipulation may offer additional therapeutic options

    Recently, a class of endogenous species of RNA called circular RNA (circRNA) has been shown to regulate gene expression in mammals and their role in cellular function is just beginning to be understood. To investigate the role of circRNAs in ovarian cancer, we performed paired-end RNA sequencing of primary sites, peritoneal and lymph node metastases from three patients with stage IIIC ovarian cancer. We developed an in-house computational pipeline to identify and characterize the circRNA expression from paired-end RNA-Seq libraries. This pipeline revealed thousands of circular isoforms in Epithelial Ovarian Carcinoma (EOC). These circRNAs are enriched for potentially effective miRNA seed matches. A significantly larger number of circRNAs are differentially expressed between tumor sites than mRNAs. Circular and linear expression exhibits an inverse trend for many cancer related pathways and signaling pathways like NFkB, PI3k/AKT and TGF-β typically activated for mRNA in metastases are inhibited for circRNA expression. Further, circRNAs show a more robust expression pattern across patients than mRNA forms indicating their suitability as biomarkers in highly heterogeneous cancer transcriptomes. The consistency of circular RNA expression may offer new candidates for cancer treatment and prognosis.

    Full Text Available BackgroundPulmonary mucoepidermoid carcinoma (PMEC and pulmonary adenoid cystic carcinoma (PACC are the two major types of primary salivary gland-type (PSGT lung cancers. The demographic profile, clinicopathological features, and predictors of survival as an overall group have not been described for PSGT cancers of lung.MethodsIn this study, we analyzed demographic, clinical, and survival data from 1,032 patients (546 PMEC and 486 PACC who were diagnosed of PSGT lung cancer in the Surveillance, Epidemiology and End Results database from 1973 to 2014.ResultsThe PSGT constituted 0.09% of all lung cancers with age-adjusted incidence rate of 0.07 per 100,000 person-years and change of −32% from 1973 to 2014. The incidence of PMEC was slightly higher than PACC but there were no differences in the age and sex distribution. PACCs (55% were significantly higher at trachea and main bronchus while PMECs were more common at peripheral lungs (85%. Most of the tumors were diagnosed at an early stage and were low grade irrespective of histology. As compared to PMEC, significantly higher number of patients with PACC underwent radical surgery and received adjuvant radiation. The 1- and 5-year cause-specific survival was 76.6 and 62.8%, respectively. On multivariate analysis, the survival was affected by age at diagnosis, tumor stage, histological grade, period of diagnosis, and surgical resection. The histology showed strong interaction with time and hazard ratio of patients with PACC was significantly worse than patients with PMEC only after 5 years.ConclusionThe incidence of pulmonary PSGT cancer is 7 cases per 10 million population in the United States and is decreasing. There was no difference between demographic profile of patients with PMEC and PACC but pathological features were diverse. The difference in the survival of patients with the two histological types surfaced only after 5 years when survival of patients with PMEC was better than PACC.

    Background: Whole brain radiotherapy (WBRT) is the most common treatment for brain metastases. Survival of patients with cancer of unknown primary (CUP) presenting with brain metastases is extremely poor. A radiation program with a short overall treatment time (short-course RT) would be preferable to longer programs if it provides similar outcomes. This study compares short-course RT with 20 Gy in 5 fractions (5 x 4 Gy) given over 5 days to longer programs in CUP patients. Patients and Methods: Data regarding 101 CUP patients who received either short course WBRT (n = 34) with 5 x 4 Gy or long-course WBRT (n = 67) with 10 x 3 Gy given over 2 weeks or 20 x 2 Gy given over 4 weeks for brain metastases were analyzed retrospectively. Six additional potential prognostic factors were investigated: age, gender, Karnofsky performance score (KPS), number of brain metastases, extracranial metastases, RPA-(Recursive Partitioning Analysis-)class. Results: On univariate analysis, the radiation program was not associated with survival (p = 0.88) nor intracerebral control (p = 0.36). Improved survival was associated with KPS ≥ 70 (p < 0.001), absence of extracranial metastases (p < 0.001), and RPA-class 1 (p < 0.001). On multivariate analyses, KPS (risk ratio [RR]: 4.55; p < 0.001), extracranial metastases (RR: 1.70; p = 0.018), and RPA-class (RR: 2.86; p < 0.001) maintained significance. On univariate analysis, KPS (p < 0.001) and RPA-class (p < 0.001) were significantly associated with intracerebral control. On multivariate analyses, KPS (RR: 2.72; p < 0.001) and RPA-class (RR: 2.09; p < 0.001) remained significant. Conclusion: Short-course WBRT with 5 x 4 Gy provided similar intracerebral control and survival as longer programs for the treatment of brain metastases in CUP patients. 5 x 4 Gy appears preferable because it is more convenient for patients.

    To determine whether the relative metabolic activity of pelvic or para-aortic LN compared with that of primary tumor measured by preoperative [{sup 18}F]FDG PET/CT scan has prognostic value in patients with endometrioid endometrial carcinoma. We retrospectively reviewed patients with endometrioid endometrial carcinoma who underwent preoperative [{sup 18}F]FDG PET/CT scans. Prognostic values of PET/CT-derived metabolic variables such as maximum standardized uptake value (SUV) of the primary endometrial carcinoma (SUV{sub Tumor}) and LN (SUV{sub LN}), and the LN-to-endometrial carcinoma SUV ratio (SUV{sub LN} / SUV{sub Tumor}) were assessed. Clinico-pathological data, imaging data, and treatment results were reviewed for 107 eligible patients. Median post-surgical follow-up was 23 months (range, 6-60), and 7 (6.5%) patients experienced recurrence. Regression analysis showed that SUV{sub LN} / SUV{sub Tumor} (P < 0.001), SUV{sub LN} (P = 0.003), International Federation of Gynecology and Obstetrics (FIGO) stage (P = 0.006), and tumor grade (P = 0.011) were risk factors of recurrence. Multivariate regression analysis revealed that FIGO stage (P = 0.034) was the independent risk factor of recurrence. SUV{sub LN} / SUV{sub Tumor} showed significant correlation with FIGO stage (P < 0.001), LN metastasis (P < 0.001), lymphovascular space invasion (P < 0.001), recurrence (P = 0.001), tumor grade (P < 0.001), and deep myometrial invasion of tumor (P = 0.022). Patient groups categorized by SUV{sub LN} / SUV{sub Tumor} showed significant difference in progression-free survival (Log-rank test, P = 0.001). Preoperative SUV{sub LN} / SUV{sub Tumor} measured by [{sup 18}F]FDG PET/CT was significantly associated with recurrence, and may become a novel prognostic factor in patients with endometrioid endometrial carcinoma.

    To determine the frequency of occult (node negative) cervical lymph node metastasis in primary head and neck squamous cell carcinoma, using contrast enhanced computed tomography (CT). Study Design: Cross sectional descriptive study. Place and Duration of Study: Study was conducted in Department of Radiology, Combined Military Hospital Rawalpindi. Duration of the study was 06 months i.e. from 19th February 2011 to 19th August 2011. Patients and Methods: A total of 141 cases, fulfilling the inclusion criteria, reporting to the radiology department, were included in the study after seeking written informed consent. All patients underwent contrast enhanced CT scan of the neck from base of skull to root of neck using Asteion Whole Body X-ray CT Scanner (Model TSX-021A). Images were evaluated for the presence or absence of cervical lymph node metastasis according to the cervical lymph node metastatic criteria at each level of the neck. Results: Of the 141 patients with clinically no head and neck squamous cell carcinoma, 45.4% were found to have lymph node metastases. Frequency of occult metastases in squamous cell carcinoma of oral cavity was 47.6%, oropharynx 23.5%, larynx 33.3% and hypopharynx 78.6%. Conclusion: In clinically node negative neck, the risk of lymph node metastases is significantly high in patients of head and neck squamous cell carcinoma in our population. All patients presenting with node negative neck should undergo CT scans for early detection of occult metastasis. (author)

    Objective: To study the correlation between the CT features of tumor blood supplies and the pathological changes in primary hepatocellular carcinoma (PHCC). Methods: Fifty cases with surgically and pathologically proved PHCC underwent spiral CT scanning (plain + dual-phase). One research group blindly evaluated the CT films obtained. According to tumor contrast enhancement and signals showed on CT, the patterns of PHCC was divided into 4 types: arterial blood supplying, portal blood supplying, arterial combining with portal blood supplying, and poorly blood supplying. Microscopically, PHCC was respectively classified into grade I to IV with Edmonson's standard, and into 4 types (trabecular, pseudo-glandular, compact, scirrhous) with WHO histological grading standard. At last, the CT features of tumor blood supplies were correlated with pathologic changes. Results: 36(72%) cases were supplied by hepatic arterial blood, 6(12%) by arterial combining with portal blood supplying, 4(8%) by portal, and 4(8%) were poorly blood supplying. The patterns of tumor blood supplies in PHCC correlated with tumor cells differentiation (P<0.05). PHCC with better tumor cells differentiation was more associated with portal blood supplies. The patterns of tumor blood supplying in PHCC correlated with the histological type of the tumor cell (P < 0.05). All of the scirrhous PHCC were lack of blood supplies, the entire compact and most of the trabecular PHCC were supplied by a arterial blood. Conclusion: The most of PHCC were supplied by hepatic arterial blood and others were supplied by portal blood, arterial combining with portal blood or lack of blood supplies. Evaluation of tumor blood supplies in PHCC is considered to be useful in differential diagnosis and treatment of PHCC

    Purpose: To assess the computed tomography (CT) findings of primary pulmonary lymphoepithelioma-like carcinoma (LELC). Materials and methods: Clinical information and CT findings of 41 patients with pulmonary LELC were reviewed. CT images of 2 or 5 mm thickness were obtained with a pre-treatment CT and were jointly evaluated by two radiologists. Results: Thirty central tumors and 11 peripheral tumors with diameters ranging from 1.0 to 8.7 cm (mean, 4.1 ± 1.9 cm) were identified. Central tumors appeared to be larger than peripheral tumors (P = 0.017). Tumors occurred more frequently in right middle lobe (31.7%) and left lower lobe (29.3%). CT findings of patients with early stage were similar to those observed in patients with advanced stage except that lymphadenopathy was significantly more common in patients with advanced stage. CT findings of pulmonary LELC consisted of well defined border (63.4%), lobulation (78.0%), vascular or bronchial encasement (43.9%), obstructive pneumonia (41.5%), pleural effusion (12.2%) and calcification (4.9%). On contrast-enhanced CT scans, inhomogeneously enhanced tumors were significantly larger than homogeneously enhanced tumors (P < 0.001). Lymphadenopathy was seen in 28 patients, and lymph nodes with homogeneous enhancement were observed in 24/28 patients. Enlarged lymph nodes were more frequently occurred in peribronchial or hilar nodes (53.7%), subcrinal nodes (39.0%), right lower paratracheal nodes (31.7%) and right upper paratracheal nodes (22.0%). Conclusion: Pulmonary LELC usually appeared as a large, central, well defined and lobulated tumor with vascular or bronchial encasement and obstructive pneumonia. Calcification was rare in pulmonary LELC. Lymphadenopathy was common, usually with homogeneous enhancement.

    In this study, the optical data of tongue color of different syndromes in primary hepatic carcinoma (PHC) were detected by optical spectrum colorimetry, and the chromaticity of tongue color was compared and analyzed. The tongue color characteristics of different syndromes in PHC and the relationship between different syndromes and tongue color were also investigated. Tongue color data from 133 eligible PHC patients were collected by optical spectrum colorimetry and the patients were divided into 4 syndrome groups according to their clinical features. The syndrome groups were liver depression and spleen deficiency (LDSD), accumulation of damp-heat (ADH), deficiency of liver and kidney yin (DLKY), and qi stagnation and blood stasis (QSBS). The variation characteristics of chromaticity coordinates, dominant wavelength, excitation purity and the distribution in the International Commission on Illumination (CIE) LAB uniform color space were measured. At the same time, the differences of overall chromatism, clarity, chroma, saturation and hue were also calculated and analyzed. PHC patients in different syndrome groups exhibited differences in chromaticity coordinates. The dominant wavelength of QSBS was distinctly different from that of the other 3 syndromes. Excitation purity in the syndromes of LDSD, ADH and DLKY showed gradual increases (Pcolorimetry technology. Different syndromes in PHC exhibit distinct chromatisms of tongue color through the calculation and analysis of chromaticity parameters of CIE, combined with colorimetric system and CIE LAB color space, and these are consistent with the characteristics of clinical tongue color. Applying optical spectrum colorimetry technology to tongue color differentiation has the potential to serve as a reference point in standardizing traditional Chinese medicine syndrome classification in PHC.

    To analyze patterns of local-regional failure after primary intensity modulated radiotherapy (IMRT) for nasopharyngeal carcinoma (NPC). A total of 370 non-metastatic NPC patients consecutively treated with IMRT (with or without chemotherapy) were analyzed. Radiotherapy was administered using a simultaneous integrated boost (SIB) technique at the total prescribed dose of 66-70.4Gy (2.0-2.2Gy per fraction). The location and extent of local-regional failures were transferred to the pretreatment planning computed tomography (CT) for dosimetric analysis. The dose of radiation received by V recur (volume of recurrence) was calculated and analyzed with dose-volume histogram (DVH). Failures were classified as: 'in field' if 95% of V recur was within the 95% isodose, 'marginal' if 20% to 95% of V recur was within the 95% isodose, or 'outside' if less than 20% of V recur was inside the 95% isodose. With a median follow up of 26 months, 25 local-regional failures were found in 18 patients. The 1- and 2-year actuarial local-regional control rates for all patients were 99.7% and 95.5% respectively. Among the 22 local–regional failures with available diagnostic images, 16 (64%) occurred within the 95% isodose lines and were considered in-field failures; 3 (12%) were marginal and 3 (12%) were outside-field failures. Intensity-modulated radiotherapy provides excellent local-regional control for NPC. In-field failures are the main patterns for local-regional recurrence. Reducing the coverage of critical adjacent tissues in CTV purposefully for potential subclinical diseases was worth of study. Great attention in all IMRT steps is necessary to reduce potential causes of marginal failures. More studies about radioresistance are needed to reduce in-field failures

A total of 221 cases of patients' imaging data with MRI examination(including ESWAN sequence) diagnosed as primary HCC were retrospectively analyzed.All the patients were collected from January 2014 to September 2015 in the First Affiliated Hospital of Dalian Medical University.The differences of R2(*) values in different MR types of HCC were analyzed.All patients were divided into infiltration group and non-infiltration group, tumor thrombus group and non-tumor thrombus group, the R2(*) values of the paired groups were compared.The diagnostic efficiency of R2(*) in HCC infiltration and tumor thrombus were evaluated by ROC curve, and to find out the threshold values. The MR types of 221 patients included 90 cases of nodular type, 62 cases of massive type, 69 cases of diffuse type.70 patients had tumor thrombus.The R2(*) values of different MR types were (21.82±8.52), (24.17±8.84)and (34.45±11.73) Hz, respectively.There was no statistically significant difference between the nodular and the massive types (P=0.144), while the difference between the nodular and diffuse type, the massive and diffuse types were statistically significant(P=0.000). The R2(*) values of infiltration group and non-infiltration group were (34.45±11.73) and (22.78±8.70) Hz , the R2(*) values of tumor thrombus group and non-tumor thrombus group were (31.20±12.17) and (24.21±9.90) Hz, the difference also had statistically significant(t=7.397 and 4.534, P=0.000 and 0.000). The AUC of R2(*) values for infiltration and tumor thrombus were 0.804, 0.681. R2(*) ≥24.68 Hz was the threshold value to diagnose the infiltration and tumor thrombus. R2(*) value can be used as a MR non-enhancement quantitative index to evaluate the biological behavior of HCC.

    A rare case of primary intraosseous squamous cell carcinoma arising in an odontogenic keratocyst (OKC) is presented here, with the clinical and histologic features of the first biopsy showing characteristics of OKC and the second biopsy disclosing a squamous cell carcinoma. Immunoprofile of this case was compared with five cases of classical OKC by using cytokeratins CK5, CK14, and CK19, CD138, p63, Ki-67, p53, and bcl-2. Classic OKCs showed expected positivity, mainly in the basal and/or suprabasal layers with most antibodies, except for p53, which was negative, whereas the present case showed irregular positivity in all layers, indicating that this can be useful for differential diagnosis and suggesting a possible role in malignant transformation into primary intraosseous squamous cell carcinoma. In conclusion, immunohistochemical differences between the first biopsy of the present case and classic OKC suggest that immunohistochemistry can be helpful in cases with areas of subtle initial malignant transformation.

    Geske, Michael J; Bloomer, Michele M; Kersten, Robert C; Vagefi, M Reza

    Orbital metastasis of hepatocellular carcinoma is exceedingly rare and caries a grave prognosis. Three cases of metastatic orbital hepatocellular carcinoma in which the primary tumor was initially unknown and the diagnostic challenges encountered are presented. With hepatocellular carcinoma, open biopsy and palliative tumor debulking has an increased bleeding risk due to the highly vascular nature of the tumor and coagulopathy associated with chronic liver disease. As an alternative, fine needle aspiration biopsy should be considered for hepatocellular carcinoma with a readily accessible mass and the availability of an experienced cytopathologist.

    Cutaneous carcinosarcoma is a rare primary tumor of the skin, characterized by biphasic epithelial and mesenchymal differentiation. Due to the limited number of cases reported, there is no consensus regarding treatment and prognosis. Some authors suggest that cutaneous carcinosarcomas should be viewed as aggressive tumors, with ancillary imaging used to evaluate potential metastatic disease. Other reports demonstrate an indolent disease course, especially with epidermal-type cutaneous carcinosarcomas. We report a case of cutaneous carcinosarcoma, which we treated with electrodessication and curettage following a shave biopsy. The tumor had an epithelial component resembling a basal cell carcinoma and a fibrosarcomatous stroma. At 1-year follow-up, our patient did not show evidence of recurrence or metastasis. Our case suggests that a cutaneous carcinosarcoma with an epithelial component composed of basal cell carcinoma can be regarded as a high-risk nonmelanoma skin cancer. © The Author(s) 2015.

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

    Full Text Available ObjectiveTo explore the early diagnostic values of serum alpha-fetoprotein (AFP, gamma-glutamyltransferase Ⅱ (GGTⅡ, and Golgi protein 73 (GP73 in patients with primary hepatocellular carcinoma (PHC. MethodsThe serum specimens of 100 patients with liver diseases (50 cases of hepatitis and liver cirrhosis and 50 cases of PHC and 50 healthy people were collected in our hospital from February 2013 to February 2014. Electrochemical luminescence technique, specific immuno-membrane adsorption assay, and enzyme-linked immunosorbent assay were used to measure the serum levels of AFP, GGTⅡ, and GP73. Comparison of continuous data between multiple groups was made by analysis of variance, and comparison between two groups was made by q test. The receiver operating characteristic (ROC curves of single or combined test results were made, and the areas under the ROC curves (AUCs were calculated. The sensitivity, specificity, and AUCs of AFP, GGTⅡ, GP73, and the combined test were analyzed and compared. ResultsThe level of serum GGTⅡ in the PHC group was significantly different compared with those in the other two groups (F=16.224, P<0.05, but there was no significant difference between the normal group and the hepatitis and liver cirrhosis group (P>0.05. Significant differences in serum levels of AFP and GP73 were observed by paired comparison between the PHC group, hepatitis and liver cirrhosis group, and normal group (F=193.128, F=20.231, P<0.05 for both. When assayed alone, the specificities of GP73, GGTⅡ, and AFP were 69%, 64% and 51%, respectively, and the sensitivities were 92%, 84%, and 76%, respectively. In combined test, the specificity was 94.6% and the sensitivity was 98.8%. ConclusionThe GP73 test is the best performer in the single assays. Combined test of serum AFP, GGTⅡ, and GP73 shows a good diagnostic value for PHC with greatly improved specificity and sensitivity.

    This is a planning study investigating the dosimetric advantages of gated volumetric-modulated arc therapy (VMAT) to the end-exhale and end-inhale breathing phases for patients undergoing stereotactic treatment of primary renal cell carcinoma. VMAT plans were developed from the end-inhale (VMATinh) and the end-exhale (VMATexh) phases of the breathing cycle as well as a VMAT plan and 3-dimensional conformal radiation therapy plan based on an internal target volume (ITV) (VMATitv). An additional VMAT plan was created by giving the respective gated VMAT plan a 50% weighting and summing the inhale and exhale plans together to create a summed gated plan. Dose to organs at risk (OARs) as well as comparison of intermediate and low-dose conformity was evaluated. There was no difference in the volume of healthy tissue receiving the prescribed dose for the planned target volume (PTV) (CI100%) for all the VMAT plans; however, the mean volume of healthy tissue receiving 50% of the prescribed dose for the PTV (CI50%) values were 4.7 (± 0.2), 4.6 (± 0.2), and 4.7 (± 0.6) for the VMATitv, VMATinh, and VMATexh plans, respectively. The VMAT plans based on the exhale and inhale breathing phases showed a 4.8% and 2.4% reduction in dose to 30 cm{sup 3} of the small bowel, respectively, compared with that of the ITV-based VMAT plan. The summed gated VMAT plans showed a 6.2% reduction in dose to 30 cm{sup 3} of the small bowel compared with that of the VMAT plans based on the ITV. Additionally, when compared with the inhale and the exhale VMAT plans, a 4% and 1.5%, respectively, reduction was observed. Gating VMAT was able to reduce the amount of prescribed, intermediate, and integral dose to healthy tissue when compared with VMAT plans based on an ITV. When summing the inhale and exhale plans together, dose to healthy tissue and OARs was optimized. However, gating VMAT plans would take longer to treat and is a factor that needs to be considered.

    To observe the primary tumor (PT) regression speed after radiotherapy (RT) in nasopharyngeal carcinoma (NPC) and evaluate its prognostic significance. One hundred and eighty-eight consecutive newly diagnosed NPC patients were reviewed retrospectively. All patients underwent magnetic resonance imaging and fiberscope examination of the nasopharynx before RT, during RT when the accumulated dose was 46–50 Gy, at the end of RT, and 3–4 months after RT. Of 188 patients, 40.4% had complete response of PT (CRPT), 44.7% had partial response of PT (PRPT), and 14.9% had stable disease of PT (SDPT) at the end of RT. The 5-year overall survival (OS) rates for patients with CRPT, PRPT, and SDPT at the end of RT were 84.0%, 70.7%, and 44.3%, respectively (P < 0.001, hazard ratio [HR] = 2.177, 95% confidence interval [CI] = 1.480-3.202). The 5-year failure-free survival (FFS) and distant metastasis-free survival (DMFS) rates also differed significantly (87.8% vs. 74.3% vs. 52.7%, P = 0.001, HR = 2.148, 95% CI, 1.384-3.333; 91.7% vs. 84.7% vs. 66.1%, P = 0.004, HR = 2.252, 95% CI = 1.296-3.912). The 5-year local relapse–free survival (LRFS) rates were not significantly different (95.8% vs. 86.0% vs. 81.8%, P = 0.137, HR = 1.975, 95% CI, 0.976-3.995). By multivariate analyses, the PT regression speed at the end of RT was the only independent prognostic factor of OS, FFS, and DMFS (P < 0.001, P = 0.001, and P = 0.004, respectively). The 5-year FFS rates for patients with CRPT during RT and CRPT only at the end of RT were 80.2% and 97.1%, respectively (P = 0.033). For patients with persistent PT at the end of RT, the 5-year LRFS rates of patients without and with boost irradiation were 87.1% and 84.6%, respectively (P = 0.812). PT regression speed at the end of RT was an independent prognostic factor of OS, FFS, and DMFS in NPC patients. Immediate strengthening treatment may be provided to patients with poor tumor regression at the end of RT

    Full Text Available The prognosis of maxillary sinus carcinomas is not very promising. Maxillary sinus carcinomas are usually diagnosed at advanced stages and the proximity of important organs such as the eyes and cranial nerves makes complete surgical resection difficult. We here present a case that presented late with squamous cell carcinoma and was treated by radiotherapy (RT followed by radical maxillectomy with en-bloc orbital exenteration. Patients who undergo RT followed by en-bloc radical maxillectomy with orbital exenteration as salvage, in these cases may have promising results. We had raised forehead fascio cutaneous flap and translocated it deep to the upper eyelid to bridge the cutaneous defect. Forehead defect was covered with split-thickness skin taken from left thigh. No microvascular surgery was done, but cosmetic results were comparable. In rural setups of developing countries where facilities for microvascular surgery are lacking flap translocation may have a positive outcome.

    [ 18 F]HX-01, a Fluorine-18 labeled berberine derivative, is a potential positron emission tomography (PET) tumor imaging agent, while [ 19 F]HX-01 is a nonradioactive reference substance with different energy state and has the same physical and chemical properties. In order to collect data for further study of [ 18 F]HX-01 PET imaging of hepatocellular carcinoma in vivo , this study compared the uptake of [ 19 F]HX-01 by human hepatocellular carcinoma and normal hepatocytes in vitro . The target compound, [ 19 F]HX-01, was synthesized in one step using berberrubine and 3-fluoropropyl 4-methylbenzenesulfonate. Cellular uptake and localization of [ 19 F]HX-01 were performed by a fluorescence microscope in human hepatocellular carcinoma HepG2, SMMC-7721 and human normal hepatocyte HL-7702. Cellular proliferation inhibition and cell cytotoxicity assay of the [ 19 F]HX-01 were conducted using cell counting kit-8 (CCK-8) on HepG2, SMMC-7721 and HL-7702 cells. Fluorescent microscopy showed that the combining ability of [ 19 F]HX-01 to the carcinoma SMMC-7721 and HepG2 was higher than that to the normal HL-7702. Cellular proliferation inhibition assay demonstrated that [ 19 F]HX-01 leaded to a dose-dependent inhibition on SMMC-7721, HepG2, and HL-7702 proliferation. Cell cytotoxicity assay presented that the cytotoxicity of [ 19 F]HX-01 to SMMC-7721 and HepG2 was obviously higher than that to HL-7702. This in vitro study showed that [ 19 F]HX-01 had a higher selectivity on human hepatocellular carcinoma cells (SMMC-7721, HepG2) but has less toxicity to normal hepatocytes (HL-7702). This could set up the idea that the radioactive reference substance [ 18 F]HX-01 may be worthy of further development as a potential molecular probe targeting human hepatocellular carcinoma using PET.

    Primary squamous cell carcinoma (SCC) of the thyroid gland is extremely rare. Infrequently, primary SCC of the thyroid gland is accompanied by other thyroid diseases such as Hashimoto's thyroiditis (HT). Recently, studies have demonstrated that differentiated thyroid cancer with coexisting HT has a better prognosis. However, the prognosis of patients with primary SCC of the thyroid gland and coexistent HT has not been clearly identified. We compared the clinical characteristics and disease stages of patients with primary SCC with and without lymphocytic thyroiditis (LT). We reviewed reports of primary SCC of the thyroid gland published in the English literature. We identified 46 papers that included 17 cases of primary SCC of the thyroid gland with LT and 77 cases of primary SCC of the thyroid gland without LT. Lymph node metastasis and local invasion rates did not differ between these two groups. Distant metastases were absent in patients with LT, and were observed in 13 (16.9%) patients without LT. A greater proportion of patients without LT had advanced stage disease (stage IV A-B-C) than patients with LT (p thyroid gland and coexisting LT had lower tumour-node-metastasis stage and frequency of distant metastasis than those without LT. Lymphocytic infiltration in patients with SCC appears to limit tumour growth and distant metastases.

    Full Text Available Objective: To analyze the malignant degree of primary hepatocellular carcinoma after endostar combined with transcatheter arterial chemoembolization (TACE treatment. Methods: A total of 68 cases of patients with primary hepatocellular carcinoma treated in our hospital from September 2011 to December 2014 were enrolled for study and divided into observation group 34 cases and control group 34 cases according to different treatment methods. Control group received transcatheter arterial chemoembolization (TACE treatment, observation group received endostar combined with TACE treatment, and then differences in serum amino acid levels, micro RNA levels, levels of GP73, GPC3, GS, etc as well as levels of ChE, TBA and AFP were compared between two groups after treatment. Results: Serum aspartic acid, leucine and arginine levels of observation group after treatment were higher than those of control group, and αα-aminoadipic acid, methionine, β-alanine and 3-methylhistidine levels were lower than those of control group; relative values of serum miR-106b, miR-222 and miR-21 expression of observation group after treatment were lower than those of control group, and relative values of miR-199a and miR-122 expression were higher than those of control group; GP73, IL-17, IL-6, GPC3, GS and HSP70 levels of observation group after treatment were lower than those of control group, and endostatin level was higher than that of control group; ChE level of observation group after treatment was higher than that of control group, and TBA and AFP levels were lower than those of control group. Conclusion: Endostar combined with TACE treatment for patients with primary hepatocellular carcinoma can effectively inhibit tumor proliferation, invasion and other malignant processes and improve liver function, and it has positive clinical significance.

    Purpose: To evaluate the applicability of carbon ion beams for the treatment of carcinoma of the lacrimal gland with regard to normal tissue morbidity and local tumor control. Methods and materials: Between April 2002 and January 2011, 21 patients with locally advanced primary epithelial carcinoma of the lacrimal gland were enrolled in a Phase I/II clinical trial of carbon-ion radiotherapy (CIRT) at the National Institute of Radiological Sciences. Acute radiation toxicity was the primary endpoint of this dose-escalation study and the late toxicity, local control, and overall survival were additionally evaluated as secondary endpoints. Of the 21 subjects enrolled, all patients were followed for more than 6 months and analyzed. Results: The radiation dose was increased from the initial dose of 48.0 Gy equivalents (GyE)/12 fractions at 10% increments up to 52.8 GyE. Of the 21 patients, five received a total dose of 48.0 GyE, and 16 received a total dose of 52.8 GyE. No patient developed grade 3 or higher skin toxicity. As late ocular/visual toxicity, three patients had grade 3 retinopathy and seven patients lost their vision. Among the 10 patients treated until May 2005, five patients had local recurrence, three of whom had marginal recurrence. Therefore, the margin for the CTV (clinical target volume) was set to a range according to the orbital exenteration since June 2005. After the application of the extended margin, no local recurrence has been observed. The three-year overall survival and local control rates were 82.2% and 79.0%, respectively. Conclusion: CIRT can be applied for primary epithelial carcinoma of the lacrimal gland, with a borderline acceptable morbidity and sufficient antitumor effect when an extended margin is adopted

    To make sure the feasibility with (18F)FDG PET/CT to guided dynamic intensity-modulated radiation therapy (IMRT) for nasopharyngeal carcinoma patients, by dosimetric verification before treatment. Chose 11 patients in III~IVA nasopharyngeal carcinoma treated with functional image-guided IMRT and absolute and relative dosimetric verification by Varian 23EX LA, ionization chamber, 2DICA of I'mRT Matrixx and IBA detachable phantom. Drawing outline and making treatment plan were by different imaging techniques (CT and (18F)FDG PET/CT). The dose distributions of the various regional were realized by SMART. The absolute mean errors of interest area were 2.39%±0.66 using 0.6 cc ice chamber. Results using DTA method, the average relative dose measurements within our protocol (3%, 3 mm) were 87.64% at 300 MU/min in all filed. Dosimetric verification before IMRT is obligatory and necessary. Ionization chamber and 2DICA of I'mRT Matrixx was the effective dosimetric verification tool for primary focal hyper metabolism in functional image-guided dynamic IMRT for nasopharyngeal carcinoma. Our preliminary evidence indicates that functional image-guided dynamic IMRT is feasible.

    The goal of this study was to isolate cancer stem-like cells marked by high expression of CD44, a putative cancer stem cell marker, from primary oral squamous cell carcinomas and identify distinctive gene expression patterns in these cells. From 1 October 2013 to 4 September 2015, 76 stage III-IV primary oral squamous cell carcinoma of the gingivobuccal sulcus were resected. In all, 13 tumours were analysed by immunohistochemistry to visualise CD44-expressing cells. Expression of CD44 within The Cancer Genome Atlas-Head and Neck Squamous Cell Carcinoma RNA-sequencing data was also assessed. Seventy resected tumours were dissociated into single cells and stained with antibodies to CD44 as well as CD45 and CD31 (together referred as Lineage/Lin). From 45 of these, CD44 + Lin - and CD44 - Lin - subpopulations were successfully isolated using fluorescence-activated cell sorting, and good-quality RNA was obtained from 14 such sorted pairs. Libraries from five pairs were sequenced and the results analysed using bioinformatics tools. Reverse transcription quantitative polymerase chain reaction was performed to experimentally validate the differential expression of selected candidate genes identified from the transcriptome sequencing in the same 5 and an additional 9 tumours. CD44 was expressed on the surface of poorly differentiated tumour cells, and within the The Cancer Genome Atlas-Head and Neck Squamous Cell Carcinoma samples, its messenger RNA levels were higher in tumours compared to normal. Transcriptomics revealed that 102 genes were upregulated and 85 genes were downregulated in CD44 + Lin - compared to CD44 - Lin - cells in at least 3 of the 5 tumours sequenced. The upregulated genes included those involved in immune regulation, while the downregulated genes were enriched for genes involved in cell adhesion. Decreased expression of PCDH18, MGP, SPARCL1 and KRTDAP was confirmed by reverse transcription quantitative polymerase chain reaction. Lower expression of

    2018-05-01

    Full Text Available Esophageal large-cell neuroendocrine carcinoma (NEC is a rare malignant tumor that is characterized by high-grade malignancy and a poor prognosis. However, the rarity of esophageal NEC has prevented the development of an established treatment, and no reports have described a discrepancy in the effectiveness of cisplatin plus irinotecan between primary and metastatic lesions. A 43-year-old Japanese man was referred to our hospital with refractory epigastralgia. A previous gastrointestinal endoscopy had revealed a 50-mm type 2 tumor in the abdominal esophagus. The pathological findings indicated poorly differentiated squamous cell carcinoma. Contrast-enhanced computed tomography revealed a metastatic liver tumor. One cycle of fluorouracil and cisplatin was not effective, and endoscopy was repeatedly performed. The pathological findings indicated a large-cell malignant tumor with tumor cells that were positive for CD56, synaptophysin, and Ki-67 (> 80%. Based on a diagnosis of esophageal large-cell NEC with a metastatic liver tumor, the patient received cisplatin plus irinotecan biweekly. After 4 months, computed tomography revealed marked shrinkage of the metastatic tumor, but the patient complained of dysphagia. Endoscopy revealed enlargement of the primary tumor, which was then treated using radiotherapy plus fluorouracil and cisplatin. The primary tumor subsequently shrank, and the patient’s symptoms were relieved, but the metastatic tumor grew. Thus, chemoradiotherapy could be an option for managing a primary esophageal large-cell NEC that does not respond to chemotherapy alone. However, the possibility of an inconsistent response to therapy in primary and metastatic lesions should be considered.

    Carcinomas of the mesopharynx, hypopharynx, and larynx with early-stage primary tumor and with cervical lymph node metastasis, were treated by neck dissection for cervical metastasis and definitive irradiation of the primary tumor. In this study, the primary sites of the 16 cases were the mesopharynx (10), the hypopharynx (3), and the larynx (3). Twelve cases of early T stages (T1 or T2) and 15 cases of advanced N stages (N2 or N3) were chosen for this treatment concept. Neck lesions were controlled in all cases and all the primary tumors showed complete response at the end of the initial treatment. One case of mesopharyngeal cancer died due to recurrence of the primary tumor and one case of hypopharyngeal cancer died due to complicated lung cancer. The treatment modality for cases of early primary cancer and advanced cervical lymph node metastasis requires well-balanced strategies for both lesions. In these cases, optimal prognosis was obtained because of careful patient selection. The treatment strategy described in this paper should be considered for cases of early T tumors and advanced N tumors. (author)

    2014-12-01

    Full Text Available Background: The assessment of human epidermal growth factor receptor 2 (HER2 gene amplification is essential in order to identify those patients affected by advanced gastric cancer who may benefit from Trastuzumab targeted therapy. Materials and Methods: With the aim to investigate the concordance rate in HER2 status between primary gastric carcinoma (GC and synchronous lymphnode metastases, we investigated HER2 status in a cohort of 108 surgical formalin-fixed paraffin-embedded specimens of GC and matched synchronous metastatic lymph nodes collected from three different units of Anatomic Pathology in southern of Italy. Fleiss-Cohen weighted k statistics were used to assess the concordance rate of HER2 status. Results: HER2 amplification was observed in 17% of primary GCs and the overall concordance rate with corresponding nodal metastases was 90.74%. Changes in HER2 status between primary GC and matched synchronous metastases were evidenced in 10 (9.26% cases. Of these, 6 cases were HER2 amplified in the primary GC and not amplified in the metastases, while 4 were HER2 not amplified in the primary tumour and amplified in the lymph node metastases. Conclusions: Although at present the simultaneous determination of HER2 in advanced gastric cancer and corresponding metastatic lymph nodes is not mandatory, the possibility that the synchronous metastases of GC have a different HER2 status from that of the primary tumour is of remarkable significance; Indeed this may have influence on the therapeutic management and prognosis of the patients.

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

    Background: The lung is the most common site of distant metastases from hepatocellular carcinoma. Correct differentiation between metastatic hepatocellular carcinoma of the lung and primary lung cancer is sometimes difficult without biopsy. Purpose: To evaluate the usefulness of measuring the attenuations of pulmonary nodules on early-phase contrast-enhanced computed tomography (CT) for the differentiation of pulmonary metastases from hepatocellular carcinoma and primary lung cancer. Material and Methods: Thirteen patients with pulmonary metastases from hepatocellular carcinoma (nine men, four women; age 53.9±14.2 years, range 16-70 years) and 25 patients with primary lung cancer (14 men, 11 women; age 62.2±9.4 years, range 43-72 years) were retrospectively evaluated. Contrast-enhanced scans were obtained 35 s after commencing intravenous injection of contrast medium. Attenuation values and the size of the pulmonary nodules were measured on contrast-enhanced CT scans. CT and clinical features were analyzed with regard to age, sex, body surface area of the patients, the attenuation values and size of the nodules, and CT machines using univariate analysis (Fisher's exact test for binary data sets and the Mann-Whitney U test for continuous data sets). Multiple linear regression analysis was used to eliminate confounding factors. Results: The mean attenuation value of metastatic pulmonary nodules from hepatocellular carcinoma (75.7±24.9 HU) was higher than that of primary lung cancer nodules (45.8±14.4 HU) (P<0.01). Other variables such as age, sex, body surface area of the patients, CT device, and nodule size were not significant variables on multiple regression analysis. When a cut-off value of 75 HU was applied, the positive predictive value for diagnosing metastatic nodules from hepatocellular carcinoma was 100%. Conclusion: Pending confirmation in a large study, our findings suggest that there is a difference in contrast enhancement between pulmonary

    Full Text Available Abstract Introduction Primary signet-ring cell carcinoma of the urinary bladder is a rare variant of mucus-producing adenocarcinoma constituting approximately 0.5% to 2.0% of all primary carcinomas of the bladder. This tumor initially presents as a high-grade, high-stage lesion and diffusely invades the bladder wall without forming intraluminal growth. The patients have no specific symptoms, which leads to delayed diagnosis and poor prognosis. Case presentation We report the case of a 51-year-old Moroccan Berber man consulting for gross hematuria. Ultrasonography and a computed tomography scan found a bladder tumor diffusely invading the bladder wall. A histopathological examination of the tumor chips from a transurethral resection of the bladder revealed signet-ring cell adenocarcinoma. The gastrointestinal tract exploration did not reveal any other tumor localization. A radical cystectomy and adjuvant cisplatin and gemcitabine chemotherapy were therefore performed resulting in 18 months of survival without metastasis and a good quality of life within that time. Conclusion The rarity and the successful management with carboplatin and gemcitabine as adjuvant chemotherapy of this entity, which is rarely reported in the literature, are two remarkable characteristics described in this case report.

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

    Squamous cell carcinoma (SCC) of the breast is an extremely rare form of cancer, accounting for approximately 0.04% of all malignant breast tumors. To date, only a limited number of cases of SCC of the breast have been reported, and most of them presented like the usual breast carcinomas. A 39-year-old woman presented with a large breast abscess and signs of sepsis. After surgical debridement of the lesion, histopathological examination of the abscess capsule revealed the presence of SCC of the breast. The definitive treatment for the tumor consisted of modified radical mastectomy with resection of the residual lesion in the right breast. This unusual case illustrates how an apparently benign disorder such as a breast abscess might be related to a clinically occult malignancy. A review of the literature on SCC of the breast is presented.

    The aim of this study was retrospective analysis of male urethral carcinoma to assess the best therapeutic approach to the management of this tumor. A review of 36 cases of male urethral carcinoma diagnosed and treated at our center was performed. Clinical features, treatment modality and outcomes were analysed. The overall median survival time was 55.16 months. The 5-year overall and disease-free survival rate for the cohort was 49% and 23%, respectively. The 5-year survival is 67% for low-stage versus 33% for high-stage tumors and is significantly different (P=0.001). The survival was 72% for tumors of the distal urethra versus 36% for tumors of the proximal, with a P-value of 0.02. The tumor location and clinicopathological stage were the most important predictors of the disease-free and overall survival. Multimodal approach is necessary for achieving local control especially for proximal and higher stage tumors. (author)

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

    Merkel cell carcinoma (MCC) is a rare and highly aggressive neuroendocrine tumor of the skin which almost exclusively presents as a solitary tumor. It is most often seen on sun-exposed regions, historically almost exclusively on the head and neck, with only rare case reports on the extremities. Although recent studies have shown increased incidence with up to 20% on the extremities, here we present one of these rare emerging presentations, with the addition of a unique treatment option.

    2010-01-01

    Currently cervical cancer represents approximately 4 % of all cancer diagnoses, being the seventh most common cancer (1, 2). The standard management of patients with early cervical carcinoma is surgical treatment. Chemo radiation therapy is accepted as a standard of care for locally advanced disease (>= II B). Concurrent chemotherapy (usually cisplatin based) produced significantly improved survival and local relapse rates. The future development will be based on the improvement of sexual education, prevention and therapeutical modalities. (author)

    Small cell carcinoma (SmCC) of the head and neck is an extremely rare neuroendocrine malignancy. In this study, we describe the incidence and determinants of survival of patients with SmCC of the head and neck between the years of 1973 and 2012 using the Surveillance, Epidemiology, and End Results database as differed by primary site. Retrospective, population-based cohort study. A total of 237 cases of SmCC of the head and neck were identified, which was divided into sinonasal primaries (n = 82) and all other head and neck primaries (n = 155). Clinicopathologic and epidemiologic variables were analyzed as predictors of overall survival (OS) and disease-specific survival (DSS) based on the Kaplan-Meier method. More than half of sinonasal primaries presented with Kadish stage C or D. On multivariate analysis, surgery was the only independent predictor of improved DSS (P = .008) for sinonasal primaries; in contrast, radiation therapy was a favorable prognosticator for OS (P = .007) and DSS (P = .043) in extrasinonasal sites. Comparison of survival between sinonasal primaries and all other sites demonstrated that sinonasal SmCC had uniformly better OS (P = .002) and DSS (P = .006). SmCC in the head and neck remains rare, and sinonasal primaries appear to have improved survival compared to other sites. Based on these results, optimal treatment for sinonasal SmCC appears to be surgical therapy, whereas radiation therapy is the preferred treatment for SmCC of other primary sites, particularly the larynx. 4.

    In order to evaluate diagnostic effectiveness of the infusion-study, the authors prospectively evaluated hepatic digital subtraction angiography of bolus and infusion studies in 71 patients with hepatocellular carcinoma. In contrast to Bolus-DSA, which involves a 2 second injection of 10cc of contrast medium, the Infusion-DSA uses a protracted (10sec) injection, a lower injection rate, and larger total dose of contrast medium (20cc). The information yield of arterial and capillary phases of Infusion-DSA was compared with that of Bolus-DSA and graded as 'improved(+)', 'equivalent( ± )', or 'poor(-)'. Also, the contribution of Infusion-DSA to the diagnosis was classified into one of five in a graded system. In 29 hepatocellular patients, the Infusion-DSA was helpful in detecting daughter nodules, fibrous capsule and arteriovenous shunt. Infusion-DSA is a useful complementary technique in the diagnosis of hepatocellular carcinoma and was also helpful in determining the selection of the therapeutic modality of hepatocellular carcinoma

  11. Initial-Stage Primary Intraosseous Squamous Cell Carcinoma Derived from Odontogenic Keratocyst with Unusual Keratoameloblastomatous Change of the Maxilla: A Case Report and Literature Discussion

    Directory of Open Access Journals (Sweden)

    2018-01-01

    Full Text Available Primary intraosseous squamous cell carcinoma (PIOSCC is a rare malignant neoplasm derived from odontogenic epithelial remnants in the central jaw bone. Most PIOSCCs originate from odontogenic cysts with a nonkeratinized epithelial lining, especially from radicular/residual and dentigerous cysts. There have been few reports of PIOSCCs derived from the odontogenic keratocyst (OKC, particularly those describing pathological features at the initial stage. The diagnosis of PIOSCC is difficult and based on exclusion of other carcinomas, including metastatic tumors from other primary sites. Here, we report an extremely rare case of initial-stage PIOSCC derived from the OKC with unusual keratoameloblastomatous change of the maxilla.

    Primary hepatic small cell carcinoma (HSCC) is a rare malignancy that has previously been described in only few case reports. The clinicopathological course, natural history, molecular markers and ideal treatment strategy for this tumor have not been fully elucidated. Herein, we report on two cases of spontaneously arising, metastatic primary HSCC that were treated at our Institution. Both patients succumbed to their disease within two months of initial presentation. Both cases underwent postmortem examination and no evidence of a pulmonary or other non-hepatic small cell primary was found. Unlike pulmonary small cell tumors, these two hepatic primaries showed only locoregional spread and very few distant metastases. Formalin-fixed samples were obtained at autopsy and sequenced using single-nucleotide polymorphism arrays and whole-genome sequencing. Four mutations in the epidermal growth factor receptor (EGFR) gene known to be associated with response to tyrosine kinase inhibitors (TKIs) were detected in one of the two HSCC samples. A systematic review and pooled analysis of all previously reported cases of primary HSCCs was conducted. The median overall survival was estimated at 4 months. Surgical resection was significantly associated with longer overall survival (hazard ratio =0.13, 95% confidence interval=0.03-0.69). Although several case reports of primary HSCC have been reported prior to this publication, to our knowledge this is the first time that molecular and systematic analysis has been conducted in order to more fully characterize this rare disease. Our results indicate that surgical resection, when feasible, may be a valid option in primary HSCC, and that some tumors may respond to TKIs against EGFR.

    Although the phenomenon of transposition has been known for over 60 years, its overarching importance in modifying and streamlining genomes took some time to recognize. In spite of a robust understanding of transposition of some TE, there remain a number of important TE groups with potential high genome impact and unknown transposition mechanisms and yet others, only recently identified by bioinformatics, yet to be formally confirmed as mobile. Here, we point to some areas of limited understanding concerning well established important TE groups with DDE Tpases, to address central gaps in our knowledge of characterised Tn with other types of Tpases and finally, to highlight new potentially mobile DNA species. It is not exhaustive. Examples have been chosen to provide encouragement in the continued exploration of the considerable prokaryotic mobilome especially in light of the current threat to public health posed by the spread of multiple Ab R .

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

    Full text: In this paper we present our early experience with a new radio-conjugate, namely rhenium-188 HDD Lipiodol (Re-188 lipiodol). Imported radiopharmaceuticals are generally expensive, particularly for developing countries. A Tungsten (W-188-Re 188) generator obtained from ORNL (Oak Ridge National Laboratory, Tennessee, USA) allows us on-site production of a beta emitting therapeutic isotope (Re-188) for up to 6 months from a single generator. The objectives of this study were to establish the safety of trans-arterial Re-188 lipiodol in patients with inoperable HCC, and determine the adverse effects and efficacy for this radio-conjugate treatment in a multi-center study of patients with advanced HCC. A multi-center study was sponsored by the International Atomic Energy Agency (Vienna) to assess the safety and efficacy of trans-arterial Re-188 HDD conjugated lipiodol (radio-conjugate) in the treatment of patients with inoperable hepatocellular carcinoma (HCC), The radio-conjugate was prepared by using a HDD (4-hexadecyl 1-2, 9, 9-tetramethyl-4, 7-diaza-1, 10-decanethiol) kit developed in Korea, and lipiodol. Over a period of eighteen months seventy patients received at least one treatment of radio-conjugate. Some patients were re-treated if there was no evidence of disease progression. The level of radio-conjugate administered was based on radiation-absorbed dose to critical normal organs, calculated following a 'scout' dose of radio-conjugate. The organs at greatest risk for radiation toxicity are the normal liver, the lung and the bone marrow. A specially designed spreadsheet was used to determine maximum tolerated activity (MTA), defined as the amount of radioactivity calculated to deliver no more than 12 Gray (Gy) to lungs, or 30 Gy to liver, or 1.5 Gy to bone marrow. These doses have been found to be safe in multiple trials using external beam therapy and systemically administered radiopharmaceuticals. Patients were followed for at least twelve weeks

    Full Text Available Nocardiosis is a common opportunistic infection in the immunocompromised and in patients with chronic debilitating diseases,e.g continuous ambulatory peritoneal dialysis (CAPD patients. Primary abdominal nocardiosis is rare and is indeed a very rare infection in immunocompetent persons. Only two cases have been reported in immunocompetent patients so far and this may be third case to the best of our knowledge and first in India. About 11 cases have been reported in CAPD patients and AIDS patients.We report a case of Nocardiosis in an immunocompetent young female who presented with an abdomino-pelvic mass masquerading as carcinoma ovary.After initial resistance to various antibiotics, she responded to intraperitoneal and oral linezolid and oral ciprofloxacin.

    This paper reports a study of forty-seven patients with esophageal carcinoma who were treated definitively with radiation therapy (n = 18) and radical surgery (n = 18) or received palliative treatment (n = 11) at the Medical College of Virginia between 1967 and 1982. The average intervals between diagnosis and death were 5, 7, and 4 months, respectively. Autopsy revealed that 80% with radiation therapy and 50% in the surgery group had persistent local-regional disease. Eleven of 36 had adrenal metastasis and eight of 36 had a second primary in the head, neck, lung or prostate. The data show a significant incidence of persistent disease in spite of negative surgical margins. Additional treatment with chemotherapy or postoperative radiation therapy should be considered

    1991-01-01

    Patients with muscle invasive carcinoma of the urinary bladder were examined with contrast-enhanced CT of the primary tumor. A specially designed technique was developed to increase the diagnostic potential of CT. The most important points about the technique were controlled filling of the bladder, the use of thin slices, series of scans before and after intravenous injection of contrast medium, and long scanning times in the precontrast series. The absorbed dose to the patient resulting from the new technique was found to be within the range of the dose from urography or barium enema. This dose was considered to be acceptable given the diagnostic gain of the procedure. Features of irradiated bladder tumors were analysed to find which parameter correlated with persistent malignancy. High contrast enhancement of a tumor relative to the bladder wall was found to be the best indicator of a malignant tumour after irradiation. 127 refs

    Conclusions: Cancer-specific survival is statistically comparable for primary and deferred cystectomy in T1 bladder cancer, although there is a non-significant difference in favor of primary cystectomy. In the deferred cystectomy group, the number of TURBTs beyond three is associated with lower survival. Conservative treatment should be adopted for most cases in this category.

  2. Pancreatic Metastasis of High-Grade Papillary Serous Ovarian Carcinoma Mimicking Primary Pancreas Cancer: A Case Report

    Full Text Available Introduction. Reports of epithelial ovarian carcinomas metastatic to the pancreas are very rare. We herein present a metastasis of high grade papillary serous ovarian cancer to mid portion of pancreas. Case. A 42-year-old patient was admitted with a non-specified malignant cystic lesion in midportion of pancreas. She had a history of surgical treatment for papillary serous ovarian adenocarcinoma. A cystic lesion was revealed by an abdominal computerized tomography (CT performed in her follow up . It was considered as primary mid portion of pancreatic cancer and a distal pancreatectomy was performed. The final pathology showed high-grade papillary serous adenocarcinoma morphologically similar to the previously diagnosed ovarian cancer. Discussion. Metastatic pancreatic cancers should be considered in patients who present with a solitary pancreatic mass and had a previous non-pancreatic malignancy. Differential diagnosis of primary pancreatic neoplasm from metastatic malignancy may be very difficult. A biopsy for tissue confirmation is required to differentiate primary and secondary pancreatic tumors. Although, the value of surgical resection is poorly documented, resection may be considered in selected patients. Conclusion. Pancreatic metastasis of ovarian papillary serous adenocarcinoma has to be kept in mind when a patient with pancreatic mass has a history of ovarian malignancy.

  3. FLI1 Expression in Breast Cancer Cell Lines and Primary Breast Carcinomas is Correlated with ER, PR and HER2

    Full Text Available FLI1 is a member of ETS family of transcription factors that regulate a variety of normal biologic activities including cell proliferation, differentiation, and apoptosis. The expression of FLI1 and its correlation with well-known breast cancer prognostic markers (ER, PR and HER2 was determined in primary breast tumors as well as four breast cancer lines including: MCF-7, T47D, MDA-MB-231 and MDA-MB-468 using RT-qPCR with either 18S rRNA or ACTB (β-actin for normalization of data. FLI1 mRNA level was decreased in the breast cancer cell lines under study compared to the normal breast tissue; however, Jurkat cells, which were used as a positive control, showed overexpression compared to the normal breast. Regarding primary breast carcinomas, FLI1 is significantly under expressed in all of the stages of breast cancer upon using 18S as an internal control. This FLI1 expression was correlated with ER, PR and HER2 status. In conclusion FLI1 can be exploited as a preliminary marker that can predict the status of ER, PR and HER2 in primary breast tumors.

    Full Text Available A seven-year-old male, an intact miniature Schnauzer dog with history of vomiting, abdominal distention, anorexia, and dyspnea was referred for further evaluation and treatment. Thoracic radiographs showed the well marginated solitary mass with soft density in the right caudal lung field, and abdominal radiographs showed signs of ascites, such as abdominal distention and moderate serosal detail loss. On ultrasonograph and computed tomograph, it was observed that the mass compressed the caudal vena cava (CVC and adhered to the heart. Exploratory thoracotomy was performed, and then it was showed that mass adhered heart, CVC, and diaphragm. The mass was fully resected although adhered part of CVC could not be completely resected. On histopathological findings, the mass was diagnosed as small-cell anaplastic carcinoma.

  7. MiRNA-21 Expression Decreases from Primary Tumors to Liver Metastases in Colorectal Carcinoma.

    Directory of Open Access Journals (Sweden)

    Fabian Feiersinger

    Full Text Available Metastasis is the major cause of death in colorectal cancer patients. Expression of certain miRNAs in the primary tumors has been shown to be associated with progression of colorectal cancer and the initiation of metastasis. In this study, we compared miRNA expression in primary colorectal cancer and corresponding liver metastases in order to get an idea of the oncogenic importance of the miRNAs in established metastases.We analyzed the expression of miRNA-21, miRNA-31 and miRNA-373 in corresponding formalin-fixed paraffin-embedded (FFPE tissue samples of primary colorectal cancer, liver metastasis and healthy tissues of 29 patients by quantitative real-time PCR.All three miRNAs were significantly up-regulated in the primary tumor tissues as compared to healthy colon mucosa of the respective patients (p < 0.01. MiRNA-21 and miRNA-31 were also higher expressed in liver metastases as compared to healthy liver tissues (p < 0.01. No significant difference of expression of miRNA-31 and miRNA-373 was observed between primary tumors and metastases. Of note, miRNA-21 expression was significantly reduced in liver metastases as compared to the primary colorectal tumors (p < 0.01.In the context of previous studies demonstrating increased miRNA-21 expression in metastatic primary tumors, our findings raise the question whether miRNA-21 might be involved in the initiation but not in the perpetuation and growth of metastases.

    Full Text Available Objectives: Oral Squamous Cell Carcinoma (OSCC is the most frequent oral cancer worldwide. It is known as the eighth most common cancer in men and as the fifth most common cancer in women. Cytogenetic and biochemical studies in recent decades have emphasized the necessity of providing an appropriate tool for such researches. Cancer cell culture is a useful tool for investigations on biochemical, genetic, molecular and immunological characteristics of different cancers, including oral cancer. Here, we explain the establishment process of five primary oral cancer cells derived from an Iranian population.Materials and Methods: The specimens were obtained from five oral cancer patients. Enzymatic, explant culture and magnetic-activated cell sorting (MACS methods were used for cell isolation. After quality control tests, characterization and authentication of primary oral cancer cells were performed by short tandem repeats (STR profiling, chromosome analysis, species identification, and monitoring the growth, morphology and the expression of CD326 and CD133 markers.Results: Five primary oral cancer cells were established from an Iranian population. The flow cytometry results showed that the isolated cells were positive for CD326 and CD133 markers. Furthermore, the cells were free from mycoplasma, bacterial and fungal contamination. No misidentified or cross-contaminated cells were detected by STR analysis.Conclusions: Human primary oral cancer cells provide an extremely useful platform for studying carcinogenesis pathways of oral cancer in Iranian population. They may be helpful in explaining the ethnic differences in cancer biology and the individuality in anticancer drug response in future studies.

    Objective: To evaluate the reserved liver function of the primary liver cancer treated by interventional embolization. Methods: 116 patients with primary liver cancer treated by interventional embolization were classified into three groups: the better, the lightly-damaged, and the highly-damaged according to the liver function after operation. The liver function and the reserved liver function among the three groups were analyzed with simple factor (Kruskal-Wallis) and multiple factors (Logistic). The damage of liver function was forecasted for primary liver cancer treated by interventional embolization. Results: There was no difference in the ALT, AST, CGT, ALP of the pre-operation among the three groups (P>0.05), but the difference in the ICGR15 and the grade of Child was obvious (P<0.05). The three equations forecasting group division after-operation with Logistic were counted and the total according rate was 82.76%. Conclusion: ICGR15 and the grade of Child were the better standard in evaluating the function of the primary liver cancer treated by interventional embolization. The strong evaluable evidence is provided for the interventional embolization of primary liver cancer

    Population-based data on the use of health services and diagnostic investigations for patients with cancer of unknown primary (CUP) is scarce. It is uncertain whether the pathways to diagnosis are different for CUP compared to other cancers. We performed a population-based nested matched case-control study using linked routinely collected records for Australian Government Department of Veterans' Affairs clients, 2004-2007. We compared health care consultations, hospitalisations, emergency department visits, and diagnostic procedures in the three months prior and the month of diagnosis for 281 clients registered with a diagnosis of CUP (C809) and 1102 controls randomly selected from clients registered with a first diagnosis of metastatic cancer of known primary. Overall, the median age at cancer diagnosis was 83 years. CUP patients were slightly older and had significantly more comorbidities prior to diagnosis than those with known primary. Compared to known primary, a diagnosis of CUP was significantly more likely after an emergency department visit, less specialist input, fewer invasive diagnostic procedures such as resection or endoscopy, and more non-invasive procedures such as magnetic resonance imaging. There were no differences in primary care or allied health consultations and hospitalisations. This health care pathway suggests delayed recognition of cancer and scope for improvement in the medical management of high-risk individuals presenting to primary care. The pattern of diagnostic investigations reveals under-investigation in some CUP patients but this is likely to reflect recognition of limited treatment options and poor prognosis and is consistent with clinical guidelines.

    2004-01-01

    The purpose of this study was to evaluate the ultimate neck control after primary radiotherapy and surgical salvage in laryngeal and pharyngeal cancer patients. Some 1,782 consecutive patients with squamous cell carcinoma were treated by radiotherapy. At presentation 26% of the patients had metastatic lymph nodes. A total of 298 primary or secondary nodal recurrences were seen, 159 were treated, and 53 (∼18%) were controlled. Isolated N-recurrence was fatal in 2.7% (36/1,324) of the N0 patients. Univariate actuarial analysis of nodal control demonstrated that the region of origin, T-classification, T-size, N-classification, tumor stage, differentiation, hemoglobin, and radiation time were significant prognostic factors. In a Cox analysis the independent significant parameters were gender, region of origin, N-classification, and differentiation. The conclusions were that in patients with nodal recurrence a little over half were treated and of these a third of the nodal recurrences were controlled. Significant prognostic factors in multivariate analysis were gender, region of origin, N-classification, and tumor differentiation

    Full Text Available BACKGROUND AND AIM: Squamous cell carcinoma (SCC is usually considered a disease of older people. Recently, there is a change in the occurrence of such lesions in young patients and lacking the established risk factors. CASE REPORT: A 21-year-old male reported with an innocuous gingival growth over lower incisors since a month. Within 15 days he noticed another gingival growth in same region lingually. The growths were mildly tender with no suppuration. The associated teeth were non-mobile and vital. The radiographic findings were insignificant. An excisional biopsy was performed under local anesthesia. The stained H and E section showed a hyper-parakeratinized stratified squamous surface epithelium with underlying connective tissue with collagen fibers, fibroblasts, blood vessels and areas of dense chronic inflammatory cell infiltrate. Epithelium exhibited features of dysplasia. There was a breach in the continuity of the basement membrane and the malignant epithelial cells were seen invading the connective tissue in form of thin cord. CONCLUSION: The histopathological study confirmed the diagnosis of well differentiated SCC. Oral SCC is not a disease of the elderly anymore. We also reviewed the literature of SCC in young patients. Thus biopsy is mandatory for any non-resolving gingival growth.

  13. Contrast-enhanced harmonic ultrasound imaging in ablation therapy for primary hepatocellular carcinoma.

    The success rate of percutaneous radiofrequency (RF) ablation for hepatocellular carcinoma (HCC) depends on correct targeting via an imaging technique. However, RF electrode insertion is not completely accurate for residual HCC nodules because B-mode ultrasound (US), color Doppler, and power Doppler US findings cannot adequately differentiate between treated and viable residual tumor tissue. Electrode insertion is also difficult when we must identify the true HCC nodule among many large regenerated nodules in cirrhotic liver. Two breakthroughs in the field of US technology, harmonic imaging and the development of second-generation contrast agents, have recently been described and have demonstrated the potential to dramatically broaden the scope of US diagnosis of hepatic lesions. Contrast-enhanced harmonic US imaging with an intravenous contrast agent can evaluate small hypervascular HCC even when B-mode US cannot adequately characterize tumor. Therefore, contrast-enhanced harmonic US can facilitate RF ablation electrode placement in hypervascular HCC, which is poorly depicted by B-mode US. The use of contrast-enhanced harmonic US in ablation therapy for liver cancer is an efficient approach.

    Full Text Available Objective: To study the aggressiveness of basal cell carcinoma (BCC on the mid-face location. Methods: A total of 30 patients were diagnosed using specimen biopsy with hematoxylineosin stain at Moewardi Public Hospital in Surakarta, Central Java, Indonesia. The age, gender distribution, site of the lesion, as well as clinic-pathological appearance were analyzed. Results: There were 30 patients consisting of 46.7% males and 53.3% females with ages ranging from 33 to 91 years old and with the most common occupation, such as farmers (53.6% and housewives (26.7%. Morpheaform subtypes BCC were more frequent than other types. Based on the predilection, most of the BCC were found to be in the mid-face (76.7% and using determined criteria of histopathological examination, the aggressive appearance was 77% and non-aggressive BCC was 23%. The BCC on the mid-face location was more aggressive than the other sites (P < 0.05. Conclusions: BCC is the most common skin tumor in humans with rare metastases, which might cause significant damage due to its local recurrences and aggressiveness. BCC on the mid-face is significantly more aggressive than that on the other predilection sites.

    2015-03-01

    Conclusions: Cases of metastases to the penis are very rare and often carry a grave prognosis, as it is a late manifestation of malignant disease. The average survival from the diagnosis of penile metastases in our review was just under 4 months. It is however important to be aware and recognise this rare phenomenon, and differentiate it from primary penis cancer. Treatment of penile metastases is mostly palliative, but much can be done to improve the patient's quality of life. Early correct diagnosis may also alter the treatment of the primary tumour.

    2018-06-01

    In head and neck squamous cell carcinoma (HNSCC), the occurrence of concurrent lung malignancies poses a significant diagnostic challenge because metastatic HNSCC is difficult to discern from second primary lung squamous cell carcinoma (SCC). However, this differentiation is crucial because the recommended treatments for metastatic HNSCC and second primary lung SCC differ profoundly. We analyzed the origin of lung tumors in 32 patients with HNSCC using human papillomavirus (HPV) typing and targeted next generation sequencing of all coding exons of tumor protein 53 (TP53). Lung tumors were clearly identified as HNSCC metastases or second primary tumors in 29 patients, thus revealing that 16 patients had received incorrect diagnoses based on clinical and morphological data alone. The HPV typing and mutation analysis of all TP53 coding exons is a valuable diagnostic tool in patients with HNSCC and concurrent lung SCC, which can help to ensure that patients receive the most suitable treatment. © 2018 Wiley Periodicals, Inc.

    Objective: To investigate the delineation of gross tumor volume (GTV) in locally advanced nasopharyngeal carcinoma (LANC) according to imageological changes before and after induction chemotherapy (IC) in order to decrease high dose area and protect normal tissue better. Methods: Between Mar 2010 to Jan 2011, 11 patients with LANC were enrolled and treated with TPF regimen followed by intensity-modulated radiotherapy (IMRT) with concurrent chemotherapy, target volumes were delineated based on fused CT imaging before and after IC following project determination. Tumor target volumes after and before IC were respectively delineated according to imaging tumor residues and were overlaid by CTV nx in order to ensure radical doses for the imaging tumor volume before IC, the resulting differences of tumor target volumes of IC before and after were measured and analyzed by paired t-test. Results: Before and after IC, the average volumes of GTV nx were respectively 44.72 cm 3 and 28.87 (t=3.89, P=0.003), the average volumes of GTV nd were respectively 32.76 cm 3 and 19.82 cm 3 (t=2.47, P=0.033), the volumes of maximum dose area in brainstem and spinal cord as well as eyeball decreased (t=2.93-4.59, all P<0.05). Conclusions: LANC treated by 3 cycle TPF regimen followed by IMRT with concurrent chemotherapy shows significant shrinkage of tumor volume. The volume of high dose region which caused by normally recovered tissues were decreased by re-delineation of target volume in brainstem and spinal cord as well as eyeball of CT images after IC.

    2013-05-01

    Full Text Available We present a case report of a 47-year-old woman who was admitted to our University-Hospital following diagnosis of pelvic mass. Abdominal examination revealed a tender, palpable mass on the right iliac region. At the gynecological examination uterus was regular in size. On the left side of the uterus a mass of 9 cm was observed; its surface was irregular and no mobility was found. Abdominal CT and NMR revealed massive ascites, omental cake and increased volume of both ovaries. Patient underwent longitudinal suprombelical-pubic laparotomy. After opening abdominal cavity, a free-fluid sample was taken and the results were positive for malignant cells. Typical neoplastic localizations on both ovaries, Douglas’ peritoneum, rectum, sigmoid colon and omentum were observed. Extemporaneous histological examination diagnosed a peritoneal serous papillary carcinoma. Hysterectomy with salpingo oophorectomy, total omentectomy, appendectomy, pelvic and lumbo-aortic lymphadenectomy was performed. Retroperitoneal approach to remove the whole Douglas’ peritoneum together with the pouch malignant localizations was done. Sigmoid colon and rectum were resected. A latero-terminal anastomosis with stapler was performed. All the visible abdominal maligant lesions were cut out. No transfusion was necessary. The postoperative course was regular and after seven days the patient was discharged. Chemotherapy ended the therapeutic management (six cycles of carboplatin and paclitaxel. After one year the patient is in good health and instrumental investigations (Ultrasounds, TC and NMR are negative for recurrence. Such a case is very interesting for the discrepancy between slight symptoms and severity of the disease, the solution of which was very complex requiring a skillful polyspecialized oncological team.

    Between January 1 1974 and October 31 1987, 98 patients with biopsy proven unresectable adenocarcinoma of the pancreas were treated with I-125 implants during laparotomy. Presenting symptoms were pain, jaundice, and weight loss. All patients underwent laparotomy and surgical staging. Thirty patients had T1NoMo disease, 47 patients had T2-3NoMo disease, and 21 patients had significant regional lymph node involvement (T1-3N1Mo). The surgical procedure performed was biopsy only (16 patients), gastric bypass, biliary bypass, and partial or total pancreatectomy with incomplete resection. The total activity and the number of seeds used were determined from the Memorial Sloan Kettering Cancer Center (MSKCC) nomogram. Stereoshift localization X ray films were taken 3-6 days after operation. The mean activity, minimal peripheral dose (MPD), and volume of the implants were 35 mCi, 13,660 cGy, and 53 cm3, respectively. In addition, 27 patients received postoperative external irradiation and 27 patients received chemotherapy. Postoperative complications were observed in 19 patients. These included post-operative death (1 patient), biliary fistula (4), intraabdominal abscess (4), GI bleeding (3), gastric or small bowel obstruction (6), sepsis (5), and deep vein thrombophlebitis (4). Pain relief was obtained in 37/57 patients (65%) presenting with pain. A multivariate analysis showed that four factors significantly affected survival: T stage, N stage, administration of chemotherapy, and more than 30% reduction in the size of the implant on follow-up films. The median survival for the entire group was 7 months. A subgroup of patients with T1No stage disease who received chemotherapy survived 18.5 months. The indications for I-125 seed implantation in unresectable carcinoma of the pancreas are discussed.

    Objective: To evaluate the quality of life (QOL) for patients with hepatocellular carcinoma (HCC) undergoing interventional therapy (IVT) and to discuss the clinical application value. Methods: A QOL questionnaire specially for HCC patients (completed by Chonghua Wan) was used to investigate by face to face method in 175 HCC patients undergoing IVT from 3 hospitals in Guangdong province. The investigation time was before, 1 month, and 3 months after IVT. The changes of QOL scores were evaluated in total and four domains. The main affected factors of QOL were analyzed. The QOL classification standard was established by frequency curve intercross analysis. Results: The scores (x-bar±s) were respectively 115.4 ± 45.1 (before IVT), 128.1 ± 28.3 (1 month after IVT), and 129.8 ± 46.4 (3 months after IVT) (P<0.01). Multivariate analysis showed that tumor stage, liver function, superselective catheterization or not, chemoembolization or not, and number of IVT were the most significant factors (P<0.05). According to the change curves of QOL score, 3 types of QOL were classified in this group. The score more than 150 was QOL type I and its curve was descending to recovering. The QOL score between 89 and 143 before IVT was classified as QOL type II and variational curve was constantly ascending. Scores below 83 was QOL type III and the curve was ascending to descending. Conclusion: Totally, the QOL of HCC patients was obviously improved after IVT. The improvements are closely related with the tumor stage, liver function, and the managements. The QOL classification has favorable value in the choice of IVT methods and the estimation of change tendency in QOL post IVT

  5. Functions and Epigenetic Regulation of Wwox in Bone Metastasis from Breast Carcinoma: Comparison with Primary Tumors

    Directory of Open Access Journals (Sweden)

    Paola Maroni

    2017-01-01

    Full Text Available Epigenetic mechanisms influence molecular patterns important for the bone-metastatic process, and here we highlight the role of WW-domain containing oxidoreductase (Wwox. The tumor-suppressor Wwox lacks in almost all cancer types; the variable expression in osteosarcomas is related to lung-metastasis formation, and exogenous Wwox destabilizes HIF-1α (subunit of Hypoxia inducible Factor-1, HIF-1 affecting aerobic glycolysis. Our recent studies show critical functions of Wwox present in 1833-osteotropic clone, in the corresponding xenograft model, and in human bone metastasis from breast carcinoma. In hypoxic-bone metastatic cells, Wwox enhances HIF-1α stabilization, phosphorylation, and nuclear translocation. Consistently, in bone-metastasis specimens Wwox localizes in cytosolic/perinuclear area, while TAZ (transcriptional co-activator with PDZ-binding motif and HIF-1α co-localize in nuclei, playing specific regulatory mechanisms: TAZ is a co-factor of HIF-1, and Wwox regulates HIF-1 activity by controlling HIF-1α. In vitro, DNA methylation affects Wwox-protein synthesis; hypoxia decreases Wwox-protein level; hepatocyte growth factor (HGF phosphorylates Wwox driving its nuclear shuttle, and counteracting a Twist program important for the epithelial phenotype and metastasis colonization. In agreement, in 1833-xenograft mice under DNA-methyltransferase blockade with decitabine, Wwox increases in nuclei/cytosol counteracting bone metastasis with prolongation of the survival. However, Wwox seems relevant for the autophagic process which sustains metastasis, enhancing more Beclin-1 than p62 protein levels, and p62 accumulates under decitabine consistent with adaptability of metastasis to therapy. In conclusion, Wwox methylation as a bone-metastasis therapeutic target would depend on autophagy conditions, and epigenetic mechanisms regulating Wwox may influence the phenotype of bone metastasis.

    The SafeTy Events in VIsmodEgib study (STEVIE, ClinicalTrials.gov, NCT01367665), assessed safety and efficacy of vismodegib-a first-in-class Hedgehog pathway inhibitor demonstrating clinical benefit in advanced basal cell carcinoma (BCC)-in a patient population representative of clinical practice. Primary analysis data are presented. Patients with locally advanced or metastatic BCC received oral vismodegib 150 mg/d until progressive disease, unacceptable toxicity, or withdrawal. Primary objective was safety. Efficacy variables were assessed as secondary end-points. Evaluable adult patients (N = 1215, 1119 locally advanced; 96 metastatic BCC) from 36 countries were treated; 147 patients (12%) remained on study at time of reporting. Median (range) treatment duration was 8.6 (0-44) months. Most patients (98%) had ≥1 treatment-emergent adverse event (TEAE). The incidence of the most common TEAEs was consistent with reports in previous analyses. No association between creatine phosphokinase (CPK) abnormalities and muscle spasm was observed. Serious TEAEs occurred in 289 patients (23.8%). Exposure ≥12 months did not lead to increased incidence or severity of new TEAEs. The majority of the most common TEAEs ongoing at time of treatment discontinuation resolved by 12 months afterwards, regardless of Gorlin syndrome status. Response rates (investigator-assessed) in patients with histologically confirmed measurable baseline disease were 68.5% (95% confidence interval (CI) 65.7-71.3) in patients with locally advanced BCC and 36.9% (95% CI 26.6-48.1) in patients with metastatic BCC. The primary analysis of STEVIE demonstrates that vismodegib is tolerable in typical patients in clinical practice; safety profile is consistent with that in previous reports. Long-term exposure was not associated with worsening severity/frequency of TEAEs. Investigator-assessed response rates showed high rate of tumour control. CLINICALTRIALS.GOV: NCT01367665.

    Medullary thyroid carcinoma (MTC) is characterized by a high rate of metastasis. In this study we evaluated the ability of [ 18 F]DOPA PET/ceCT to stage MTC in patients with suspicious thyroid nodules and pathologically elevated serum calcitonin (Ctn) levels prior to total thyroidectomy and lymph node (LN) dissection. A group of 32 patients with sonographically suspicious thyroid nodules and pathologically elevated basal Ctn (bCtn) and stimulated Ctn (sCtn) levels underwent DOPA PET/ceCT prior to surgery. Postoperative histology served as the standard of reference for ultrasonography and DOPA PET/ceCT region-based LN staging. Univariate and multivariate regression analyses as well as receiver operating characteristic analysis were used to evaluate the correlations between preoperative and histological parameters and postoperative tumour persistence or relapse. Primary MTC was histologically verified in all patients. Of the 32 patients, 28 showed increased DOPA decarboxylase activity in the primary tumour (sensitivity 88%, mean SUVmax 10.5). Undetected tumours were exclusively staged pT1a. The sensitivities of DOPA PET in the detection of central and lateral metastatic neck LN were 53% and 73%, in contrast to 20% and 39%, respectively, for neck ultrasonography. Preoperative bCtn and carcinoembryonic antigen levels as well as cN1b status and the number of involved neck regions on DOPA PET/ceCT were predictive of postoperative tumour persistence/relapse in the univariate regression analysis (P PET/ceCT cN1b status remained significant in the multivariate analysis (P = 0.016, relative risk 4.02). This study revealed that DOPA PET/ceCT has high sensitivity in the detection of primary MTC and superior sensitivity in the detection of LN metastases compared to ultrasonography. DOPA PET/ceCT identification of N1b status predicts postoperative tumour persistence. Thus, implementation of a DOPA-guided LN dissection might improve surgical success.

    Full Text Available Pleomorphic carcinoma is a rare lesion and the literature contains few reports of pleomorphic carcinoma of the gallbladder. The present study reports a rare case of primary pleomorphic carcinoma of the gallbladder for which we were able to perform curative surgery. A 77-year-old woman with dementia developed nausea and anorexia, and computed tomography demonstrated irregular thickening of the gallbladder wall. Drip infusion cholangiography and endoscopic retrograde cholangiopancreatography revealed no stenosis of the common and intrahepatic bile ducts. We suspected carcinoma of the gallbladder without lymph node metastasis and invasion to the common bile duct. We guessed it to be resectable and performed open laparotomy. At operation, the fundus of the gallbladder was adherent to the transverse colon, but no lymph node and distant metastases were detected. Therefore, we performed curative cholecystectomy with partial colectomy. Histopathology and immunostaining showed coexistence of an adenocarcinoma, squamous cell carcinoma and sarcomatous tumor of spindle-shaped cell, as well as transition zones between these tumors. We diagnosed stage I pleomorphic carcinoma of the gallbladder. No recurrence has been observed for one and a half years. The biological behavior of pleomorphic carcinoma of the gallbladder remains unknown. It will be necessary to accumulate more case reports of this tumor in order to define diagnostic criteria.

    The resectability of hepatocellular carcinoma is determined by the extent of hepatic involvement, the presence or absence of venous invasion and the presence or absence of extrahepatic metastasis. Extrahepatic spread to regional lymph node represent contraindication to surgical resection. Despite the importance of regional node metastasis, their CT appearance is poorly understood. 19 cases of hepatoma collected during Oct, 1982 to May, 1985 at New York Hospital-Cornell Medical center and 73 cases of hepatoma collected during Mar, 1985 to Sept, 1986 at Yonsei University Medical College were reviewed and analysed. Regional lymph node involvement were divided into four main groups with subgrouping according to the location and lymphatic pathway. 1.lymph nodes in lesser omentum: hepatic, portocaval, left gastric and celiac nodes. 2.lymph nodes around pancrease head: subpyloric, superior mesenteric, preaortic retropancreatic, and precaval retropancreatic lymph nodes. 3.paraaortic nodes: left paraaortic, interaorticocaval, retrocaval and preaortic below 3rd duodenum. 4.phrenic nodes: lower parasternal, middle phrenic and retrocrural nodes. The results were as follows: 1.The frequency of regional node involvement, cases collected at New York Hospital-Cornell Medical center, is hepatic node in 5 (26.3%), portocaval node in 8 (42.1%), left gastric in 4 (21.1%), celiac in 7 (36.8%), precaval retropancreatic in 5 (26.3%) preaortic retropancreatic in 4 (21.1%) interaorticocaval in 7 (36.8%) retrocaval in 4 (21.4%) and lower parasternal in (5.3%). 2.The frequency of regional node involvement, cases collected at Yonsei University college of Medicine, is hepatic in 20.5%, portocaval in 24.7% left gastric in 19.2% celiac in 19.2%, precaval retropancreatic in 8.2%, preaortic retropancreatic in 5.5%, left paraaortic in 12.3%, interaorticocaval in 12.3%, retrocaval in 11.0% low parasternal in 0.8%, superior mesenteric in 4.1% subpyloric 1.4% and preaortic below 3rd duodenum in 1

    Full Text Available Purpose To assess the oncologic and functional outcomes of salvage renal surgery following failed primary intervention for RCC. Materials and Methods We performed a retrospective review of patients who underwent surgery for suspected RCC during 2004-2012. We identified 839 patients, 13 of whom required salvage renal surgery. Demographic data was collected for all patients. Intraoperative and postoperative data included ischemic duration, blood loss and perioperative complications. Preoperative and postoperative assessments included abdominal CT or magnetic resonance imaging, chest CT and routine laboratory work. Estimated glomerular filtration rate (eGFR was calculated according to the Modification of Diet in Renal Disease equation. Results The majority (85% of the patients were male, with an average age of 64 years. Ten patients underwent salvage partial nephrectomy while 3 underwent salvage radical nephrectomy. Cryotherapy was the predominant primary failed treatment modality, with 31% of patients undergoing primary open surgery. Pre-operatively, three patients were projected to require permanent post-operative dialysis. In the remaining 10 patients, mean pre- and postoperative serum creatinine and eGFR levels were 1.35 mg/dL and 53.8 mL/min/1.73 m2 compared to 1.43 mg/dL and 46.6 mL/min/1.73 m2, respectively. Mean warm ischemia time in 10 patients was 17.4 min and for all patients, the mean blood loss was 647 mL. The predominant pathological stage was pT1a (8/13; 62%. Negative surgical margins were achieved in all cases. The mean follow-up was 32.9 months (3.5-88 months. Conclusion While salvage renal surgery can be challenging, it is feasible and has adequate surgical, functional and oncological outcomes.

    Pancreatic neuroendocrine tumors (PNET) are primary, usually we 11-differentiated pancreatic tumors. Their origin is not fully understood, but they are thought to develop from the pluripotent cells in the exocrine part of the pancreas. PNET are a heterogeneous group with different malignant potential. In some of the patients with sporadical forms of PNET there is association with other malignancies such as ovarian cancer, breast cancer, bladder and prostate cancers. We present a case of 50-year-old woman, with incidentally found pancreatic neoplasm, during a follow-up CT for ovarian cancer. Laparotomy and pancreatic biopsy are performed. Histological diagnosis confirms a well- differentiated endocrine tumor of the pancreas. (authors)

    Full Text Available Primary hepatic carcinoma (PHC is one of the most common malignant tumours in the world. More and more research has shown that As2O3 combined with TACE has a good curative effect in treating PHC. The objectives of this study were to evaluate the therapeutic efficacy and safety of As2O3 combined with TACE in treating PHC. The CNKI, VIP, Wanfang, PubMed, and Cochrane databases were searched from their inception until December 2015. Randomized controlled trials (RCTs comparing As2O3 combined with TACE versus TACE alone in treating PHC were identified. Stata SE 12.0 was used for data analysis. 17 RCTs with 1055 patients were included. Meta-analysis showed that, compared with TACE alone, As2O3 combined with TACE showed significant effects in improving the clinical efficacy rate (P<0.01, decreasing the value of alpha-fetoprotein (P<0.01, increasing the one-year survival rate (P<0.01, and improving the quality of life of PHC patients (P<0.01. Fifteen studies had mentioned adverse events, but no serious adverse effects were reported in any of the included trials. In conclusion, As2O3 combined with TACE therapy appears to be potentially effective in treating PHC and is generally safe. However, further studies with rigorous designs trials and multiregional cooperation trials are needed.

    No study has done a comparative analysis of radiologic imaging findings between primary nasopharyngeal lymphoma (PNL) and nasopharyngeal carcinoma (NPC). The purpose of this study was to analyze computed tomography (CT) and magnetic resonance (MR) images and to evaluate the maximum standardized uptake value (SUV max) of positron emission tomography (PET)/CT between PNL and NPC, knowing the imaging features that distinguish PNL from NPC. Cross-sectional study. University tertiary care facility. The authors analyzed the features on CT, MR imaging, and PET/CT of 16 patients diagnosed with PNL and 32 patients diagnosed with NPC histopathologically. Patients with PNL had a larger tumor volume and showed symmetry of tumor shape than did patients with NPC. Patients with PNL also had higher tumor homogeneity than NPC patients on CT, T2-weighted, and postcontrast MR images. All PNL patients showed a high degree of enhancement without invasion to the adjacent deep structure. The involvement of the Waldeyer ring was significantly higher in PNL patients. Cervical and retropharyngeal lymphadenopathy and PET/CT SUV max showed no significant difference between PNL and NPC. If the images present a bulky, symmetric nasopharyngeal mass with marked homogeneity, a high degree of enhancement, and a higher Waldeyer ring involvement combined with no invasion into the deep structure, PNL should be considered over NPC.

    Primary small cell carcinoma of the esophagus (PSCCE) is a rare and aggressive tumor with poor prognosis. The aim of this study was to investigate the existence of EGFR, KRAS, PIK3CA and PTEN mutations in PSCCE. Clinical–pathological data and paraffin-embedded specimens were collected from 38 patients. Exons 18 to 21 of EGFR, KRAS and PIK3CA status were analyzed by real-time PCR based on ARMS and Scorpion technology in all patients, and the PTEN gene was also screened using real-time PCR and high-resolution melting curve analysis (HRMA). Only 1 (2.63%) out of 38 patients had EGFR mutations in L858R missense, and KRAS and PIK3CA were not found in the mutational spot in all patients. However, PTEN mutations presented in 14 (36.84%) out of 38 patients, including exon 5 coding for PTEN missense mutation (n =4, 10.53%), exon 6 (n =7, 18.42%), concurrent exon 5 and exon 6 (n =2, 5.26%), and exon 8 (n =1, 2.63%). Concurrent mutations of these genes were not detected in all samples. No statistically significant associations were found between the clinicopathological features and the mutation status of PTEN. The incidence of PTEN mutations in Chinese patients with PSCCE was higher than that of previous reports in other histological subtypes of esophageal cancer

    Background and purpose: To develop a normal tissue complication probability (NTCP) model of radiation-induced biochemical hypothyroidism (HT) after primary radiotherapy for head and neck squamous cell carcinoma (HNSCC) with adjustment for latency and clinical risk factors. Patients and methods: Patients with HNSCC receiving definitive radiotherapy with 66–68 Gy without surgery were followed up with serial post-treatment thyrotropin (TSH) assessment. HT was defined as TSH >4.0 mU/l. Data were analyzed with both a logistic and a mixture model (correcting for latency) to determine risk factors for HT and develop an NTCP model based on mean thyroid dose (MTD) and thyroid volume. Results: 203 patients were included. Median follow-up: 25.1 months. Five-year estimated risk of HT was 25.6%. In the mixture model, the only independent risk factors for HT were thyroid volume (cm 3 ) (OR = 0.75 [95% CI: 0.64–0.85], p 3 , respectively. Conclusions: Comparing the logistic and mixture models demonstrates the importance of latent-time correction in NTCP-modeling. Thyroid dose constraints in treatment planning should be individualized based on thyroid volume

    In 31 cases of Stages I or II carcinoma of the breast treated by primary radiation therapy, the cosmetic results were analyzed with regard to the details of treatment. Three principal treatment factors were identified which influenced the cosmetic outcome: (1) the extent and location of the biopsy procedure; (2) the time/dose factors of the radiation therapy; and (3) the technique of the radiation therapy. Cosmetic results were lessened when the biopsy procedure included a wide resection of adjacent breast tissue or when the biopsy scar was obvious. Increasing doses of external beam radiation were associated with greater degrees of retraction and fibrosis of the treated breast. All 6 patients who received 6000 rad by external beam had significant retraction, and fibrosis while patients who received 5000 rad rarely showed significant changes. Local boost doses by interstitial implantation did not diminsh the cosmetic outcome. All patients were treated using supervoltage equipment without bolus and skin changes secondary to treatment were infrequent. Seventeen patients developed localized areas of fibrosis and skin changes at the matchline between adjacent radiation fields. Recommendations are made for improved cosmetic results based on these findings

    In a prospective study on 20 subsequent patients with primary cervical carcinoma in Stages I to III simulator planning of a 4-field box-technique was performed. After defining the planning target volume (PTV) in the 3D planning system the field configuration of the simulator planning was transmitted. The resulting plan was compared to a second one based on the defined PTV and evaluated regarding a possible geographical miss and encompassment of the PTV by the treated volume (ICRU). Volumes of open and shaped portals were calculated for both techniques. Planning by simulation resulted in 1 geographical miss and in 10 more cases the encompassment of the PTV by the treated volume was inadequate. For a PTV of mean 1 729 cm 3 the mean volume defined by simulation was 3 120 cm 3 for the open portals and 2 702 cm 3 for the shaped portals. The volume reduction by blocks was 13,4% (mean). With CT-based 3D treatment planning the volume of the open portals was 3,3% (mean) enlarged to 3 224 cm 3 . The resulting mean volume of the shaped portals was 2 458 ccm. The reduction compared to the open portals was 23,8% (mean). The treated volumes were 244 cm 3 or 9% (mean) smaller compared to simulator planning. The 'treated volume/planning target volume ratio' was decreased from 1.59 to 1.42. (orig.) [de

Methods Thirty one patients with HCC who were treated with SBRT were used for the study. We studied 32 HCC lesions, where 23 lesions (22 patients were treated targeting small non-resectable primary HCC, and 9 lesions (9 patients targeting PVTT using the Cyberknife. All the 9 patients targeting PVTT received TACE for the advanced HCC. Tumor volume was 3.6–57.3 cc (median, 25.2 cc and SBRT dose was 30–39 Gy (median, 36 Gy in 3 fractions for consecutive days for 70–85% of the planned target volume. Results The median follow up was 10.5 months. The overall response rate was 71.9% [small HCC: 82.6% (19/23, advanced HCC with PVTT: 44.4% (4/9], with the complete and partial response rates of 31.3% [small HCC: 26.1% (6/23, advanced HCC with PVTT: 11.1% (1/9], and 50.0% [small HCC: 56.5% (13/23, advanced HCC with PVTT: 33.3% (3/9], respectively. The median survival period of small HCC and advanced HCC with PVTT patients was 12 months and 8 months, respectively. No patient experienced Grade 4 toxicity. Conclusion SBRT for small HCC and SBRT combined with TACE for advanced HCC with PVTT showed feasible treatment modalities with minimal side effects in selected patients with primary HCC.

    Full Text Available Store-operated Ca2+ entry (SOCE is activated following depletion of the inositol-1,4,5-trisphosphate (InsP3-sensitive Ca2+ pool to regulate proliferation in immortalized cell lines established from either primary or metastatic lesions. The molecular nature of SOCE may involve both Stim1, which senses Ca2+ levels within the endoplasmic reticulum (ER Ca2+ reservoir, and a number of a Ca2+-permeable channels on the plasma membrane, including Orai1, Orai3, and members of the canonical transient receptor (TRPC1–7 family of ion channels. The present study was undertaken to assess whether SOCE is expressed and controls proliferation in primary cultures isolated from secondary lesions of heavily pretreated metastatic renal cell carcinoma (mRCC patients. SOCE was induced following pharmacological depletion of the ER Ca2+ store, but not by InsP3-dependent Ca2+ release. Metastatic RCC cells express Stim1-2, Orai1–3, and TRPC1–7 transcripts and proteins. In these cells, SOCE was insensitive to BTP-2, 10 µM Gd3+ and Pyr6, while it was inhibited by 100 µM Gd3+, 2-APB, and carboxyamidotriazole (CAI. Neither Gd3+ nor 2-APB or CAI impaired mRCC cell proliferation. Consistently, no detectable Ca2+ signal was elicited by growth factor stimulation. Therefore, a functional SOCE is expressed but does not control proliferation of mRCC cells isolated from patients resistant to multikinase inhibitors.

    Objective: To identify the factors associated with radiation-induced liver disease (RILD) and to describe the probability of RILD using the Lyman normal tissue complication(NTCP) model for primary liver carcinoma(PLC) treated with hypofractionated conformal therapy (CRT). Methods: A total of 109 PLC patients treated with hypofractionated CRT were prospectively followed according to the Child-Pugh classification for liver cirrhosis, 93 patients in class A and 16 in class B. The mean dose of radiation to the isocenter was (53.5±5.5) Gy, fractions of (4.8±0.5) Gy, with interfraction interval of 48 hours and irradiation 3 times per week. Maximal likelihood analysis yielded the best estimates of parameters of the Lyman NTCP model for all patients; Child-Pugh A and Child-Pugh B patients, respectively. Results: Of all the patients, 17 developed RILD (17/109), 8 in Child-Pugh A (8/93) and 9 in Child-Pugh B (9/16). By multivariate analysis, only the Child-Pugh Grade of liver cirrhosis was the independent factor (P=0.000) associated with the developing of BILD. The best estimates of the NTCP parameters for all 109 patients were n=1.1, m=0.35 and TD 50 (1)=38.5 Gy. The n, m, TD 50 (1) estimated from patients with Child-Pugh A was 1.1, 0.28, 40.5 Gy, respectively, compared with 0.7, 0.43, 23 Gy respectively, for patients with Child-Pugh B. Conclusions: Primary liver cancer patients who possess Child-Pugh B cirrhosis would present a significantly greater susceptibility to RILD after hypofractionated CRT than patients with Child-Pugh A cirrhosis. The predominant risk factor for developing RILD is the severity of hepatic cirrhosis in the liver of PLC patients. (authors)

    The paper presents the most important features of the macro- and microangiographic picture of the liver primary carcinomata. Arterial ramifications of the liver were injected with a contrast medium - Micropaque, the liver was cut into 0.5 cm thick slices in the vertical and horizontal plane. The angiograms revealed radiological pictures of macroscopic arterial vascularization of the liver. In order to make a microangiographic estimation, the author cut the cubes about 20 x 20 x 5 mm in sizes out of 0.5 cm thick slices. The cubes were cut frozen in a microtome into sections of a thickness 1500 μ. Microangiographic pictures were taken and assessed in 8 x magnification. According to the author, the obtained results present a great cognitive importance and will help in better assessment of angiograms performed in patients with liver carcinomata. (orig.) [de

    A technique of short-term tests in vitro by means of the incubation of tumor cell suspensions is utilized as a radioactive-biochemical method for pretherapeutic determination of the resistance in human cancers of the breast. Cell suspensions from primary tumors and metastases reveal individually different responses to cytostatics in vitro. It is possible, therewith, to differentiate two tumor collectives related to in vivo resistant or in vivo sensitive tumors. The responses of the primary lesion and the axillary lymphatic metastasis of the same carcinoma may in single cases also differ in vitro, according to clinical experience with the therapy of breast cancer. A distinct relation can be shown between the histological type of a carcinoma and its in vitro capacity of resistance.

    Purpose: This study aimed to evaluate the efficacy of high-dose-rate brachytherapy (HDRB) in the primary treatment of endometrial carcinoma. The results of 12 years of experience (1981-1992) covering 280 patients (mean age 72 years) and their follow-up over 10 years (mean 55 months) are reported. Methods and Materials: Staging was based on clinical examination and fractionated curettage. There were 116 patients in clinical Stage Ia, 119 in Stage Ib, 37 in Stage II, and 8 in Stage III. HDRB was performed four to five times (8.5 Gy) with a one-channel intracavitary applicator and one to two times (7 Gy) with an intravaginal cylinder applicator. Overall and disease-specific survival, local control according to stage and histology, and late side effects were analyzed retrospectively (actuarial method). Results: At 5 years, overall survival, disease-specific survival, and local control were 52.7%, 76.6%, and 75.4% (Stage Ia: 63.9%, 84.9%, and 86.0%; Stage Ib: 47.3%, 73.3%, and 68.8%; and Stage II: 40.2%, 68.6%, and 60.5%) according to histopathologic Grade 1: 65.1%, 83.5%, and 77.7%; for Grade 2: 44.7%, 75.4%, and 75.8%; and for Grade 3: 37.7%, 63.9%, and 74.1%. Eight patients showed progressive disease, 64 developed recurrence after a median of 13 months (45 of whom had a local recurrence only, and 6 of whom had a local recurrence with distant metastases), 6 developed a lymph node recurrence only, and 7 developed distant metastases only. The calculated probability for developing a Grade III late side effect was 5.2% at 5 years. Conclusion: At Stages Ia, Ib, and II in endometrial carcinoma, HDRB is a very effective treatment modality with acceptable local control rates and disease-specific survival for patients who are not fit for surgery. During the time frame of 12 years and in 280 patients the method has proven to have a low risk of acute complications and an acceptable risk of long-term side effects

    Carcinoma cervix is the most common gynecological malignancy among Indian women. The common symptoms at presentation include abnormal vaginal bleeding, unusual discharge from the vagina, or pain during coitus and postmenopausal bleeding. Rarely, few patients may present with distant metastases without local symptoms. We present two patients with an unusual presentation of metastatic disease without any gynecological symptoms, where 18 F-flouro deoxy glucose positron emission tomography/computed tomography helped in identifying the primary malignancy in the uterine cervix

    Among the solid malignancies, lung cancer is today the most common cancer in the world (850,000 new cases during 1990). Moreover, with an estimated increase of about 5 percent a year, it now represents the first cause of mortality for cancer in both sexes. The evidence of a close relationship between lung cancer and cigarette smoking was first pointed out by E. Graham in 1950. Since then, the responsibility of active cigarette smoking in determining lung cancer as well as that of nicotine causing addictiveness, have been assessed clearly. Nevertheless primary prevention, mainly through the campaign against cigarette smoking, has always faced great difficulties because it clashes with the economic power and interests of tobacco companies. Moreover the epidemiologic trends show a progressive increase of the disease with a silent epidemic-like worldwide diffusion, in close similarity to AIDS. So, more than 5 million new cases a year of lung cancer are expected to appear at the beginning of 2000. The primary prevention against the major factor of risk-the cigarette-is mainly based, in developed countries, through the following official measures: i) a heavy taxation on the finished goods; ii) the conversion of the tobacco growing to other crops and iii) the package-based health information for all tobacco products. On the other side, while waiting for new effective chemoprevention methods, the need of getting a true early clinical diagnosis of tumor is emphasised. Only by this means is it indeed possible to improve the rate of cure through performing conventional resections of those cancers which could be discovered in still limited clinical stage. In the same time, a strong effort for radically operating Stage III locally advanced cancers, is also attempted through the newer tracheobronchoplastic procedures as well as the other over extended resections done directly in the mediastinal area.

    Full Text Available Primary adenocarcinoma of duodenum is a very rare tumour with a prevalence of only 0.3 to 1% of among all the tumours of gastrointestinal tracts. Localised tumours, if resected have good prognosis but those with metastates entails a poor prognosis, where generally palliation may be the only feasible option. Low dose continous cytotoxic treatment or metronomic chemotherapy prevents neoangiogenesis and chemoresistance thereby, provides excellent symptom relief and palliation in many advanced heavily pretreated solid malignancies. It offers as an affordable, less toxic therapy with moderate to good efficacy. Here we report a case of a 52 year female who, presented with history of maleana, pallor and pedal edema for last 2 months. Her performance status was poor (KPS 40 and she had enlarged left supraclavicular lymph node, palpable liver and vague mass in paraumbilical region. Upper GI endoscopy revealed large ulceroproliferative growth in the D2 segment and HPE showed moderately differentiated adenocarcinoma. CT scan revealed paratracheal and retroperitoneal lymphadenopathy and bone scan revealed vertebral metastasis. Patient received oral cyclophosphamide and hematinic and vitamin support, along with radiation to spine. There was near complete clinical response, and progression free period of about 32 weeks. Thus, single agent cyclophosphamide in the present case provided near total clinical response and prolonged period of freedom from disease progression with excellent palliation of symptoms. Hence in patient of advanced and metastatic small bowel cancer, with poor performance status metronomic therapy with single agent cyclophosphamide may provide viable option both for treatment and palliation.

    Monoclonal antibody 791T/36, prepared against a tumor-associated 72,000 dalton glycoprotein, reacted with cells from primary and metastatic colorectal carcinomas. I-131 or In-111-labelled antibody localized in xenografts of colorectal carcinomas established from in vitro clonogenic populations. Clinically, with I-131-labelled antibody, 8/11 colonic tumors imaged positively. Imaging was negative in four patients with benign colon disease. 5/11 rectal tumors were positively imaged, but excreted I-131 in the bladder obscured tumors in several studies. In-111-labelled antibody gave superior images and positively imaged primary and metastatic sites in 13/14 patients. Prospectively in the detection of recurrent disease, I-131 or In-111-antibody detected 29/33 separate sites in 24 patients. Seven negative patients remain disease free. There were 3 false positives; overall sensitivity was 88%, with 70% specificity. Specific localization of radiolabel was confirmed immunochemically and by counting radioactivity in resected specimens. Antibody conjugates with methotrexate, vindesine and daunomycin retained drug activity and antibody function, including xenograft localization and conjugates were therapeutically effective against xenografts. 791T/36 antibody has potential for immunodetection of primary and recurrent colorectal carcinoma and for targeting of therapeutic agents

    Full Text Available Abstract Background Women that carry germ-line mutations for BRCA1 or BRCA2 genes are at an increased risk of developing breast, ovarian and peritoneal cancer. Primary peritoneal carcinoma is a rare tumour histologically identical to papillary serous ovarian carcinoma. Risk-reducing surgery in the form of mastectomy and oophorectomy in premenopausal women has been recommended to prevent breast and ovarian cancer occurrence and decrease the risk of developing primary peritoneal cancer. Case presentation We present a case report of a woman with a strong family history of breast cancer who underwent risk-reducing surgery in the form of bilateral salpingo-oophorectomy following a mastectomy for a right-sided breast tumour. Following the finding of a BRCA1 mutation, a prophylactic left-sided mastectomy was performed. After remaining well for twenty-seven years, she presented with rectal bleeding and altered bowel habit, and was found to have a secondary cancer of the sigmoid colon. She was finally diagnosed with primary papillary serous carcinoma of the peritoneum (PSCP. Conclusion PSCP can present many years after risk-reducing surgery and be difficult to detect. Surveillance remains the best course of management for patients with known BRCA mutations.

    Cases of primary neuroendocrine carcinoma (NEC) of the breast have been reported, though rare. We report the case of a 45-year-old woman presented with jaundice and evaluated to have liver metastasis from neuroendocrine origin. She underwent whole body positron emission tomography/computed tomography, which showed left breast lesion and bone metastasis. Fine-needle aspiration (FNA) of breast revealed a NEC. A diagnosis of a primary NEC of the breast was rendered with hepatic and bone metastasis. She was treated with peptide receptor radionuclide therapy and is on follow-up

    The purpose of this study was to find out what clinicopathologic or immunohistochemical parameter that may affect FDG uptake of primary tumor in PET/CT scan of the gastric carcinoma patient. Eighty-nine patients with stomach cancer who underwent pre-operative FDG PET/CT scans were included. In cases with perceptible FDG uptake in primary tumor, the maximum standardized uptake value (SUVmax) was calculated. The clinicopathologic results such as depth of invasion (T stage), tumor size, lymph node metastasis, tumor differentiation and Lauren's classification and immunohistochemical markers such as Ki-67 index, expression of p53, EGFR, Cathepsin D, c-erb-B2 and COX-2 were reviewed. Nineteen out of 89 gastric carcinomas showed imperceptible FDG uptake on PET/CT images. In cases with perceptible FDG uptake in primary tumor, SUVmax was significantly higher in T2, T3 and T4 tumors than T1 tumors (5.8±3.1 vs. 3.7±2.1, p=0.002). SUVmax of large tumors (above or equal to 3 cm) was also significantly higher than SUVmax of small ones (less than 3 cm) (5.7±3.2 vs. 3.7±2.0, p=0.002). The intestinal types of gastric carcinomas according to Lauren showed higher FDG uptake compared to the non-intestinal types (5.4±2.8 vs. 3.7±1.3, p=0.003). SUVmax between p53 positive group and negative group was significantly different (6.0±2.8 vs. 4.4±3.0, p=0.035). No significant difference was found in presence of LN metastasis, tumor differentiation, Ki-67 index, and expression of EGFR, Cathepsin D, c-erb-B2 and COX-2. T stage of gastric carcinoma influenced the detectability of gastric cancer on FDG PET/CT scan. When gastric carcinoma was perceptible on PET/CT scan, T stage, size of primary tumor, Lauren's classification and p53 expression were related to degree of FDG uptake in primary tumor

    Full Text Available Squamous cell carcinoma of the esophagus is frequently associated with other, synchronous or metachronous tumors, in the upper aerodigestive tract. All 264 patients with squamous cell carcinoma of the esophagus, treated in the Gastrointestinal Surgery, Esophagus section, of the "Hospital das Clínicas" (São Paulo University Medical School, Brazil, between 1979 and 1989 were analyzed retrospectively with regards to the occurrence of multiple primary tumors in the upper aerodigestive tract. Multiple primary tumors were encountered in 10 (3.8% patients. All patients were male and the mean age at the time of the first primary was 52.2 years. Tobacco smoke and alcohol were the principal carcinogens in these patients (n = 10. The sites of the tumors were: larynx (n = 4, tongue (n = 4, lung (n = 2, and oral cavity (n = 1. Two simultaneous, three synchronous and five metachronous multiple primary carcinomas were detected. The esophagus was the second primary tumor in nine patients. The mean overall survival after the diagnosis of the second primary was 2.8 months (SD = 0.89. Inquiry regarding other malignancies, associated with panendoscopy should be carry out prior to the treatment of the first primary to diagnose simultaneous or synchronous primary tumors, and careful follow-up should be performed after treatment of the first primary to detect new tumors in these high-risk patients.Carcinoma epidermóide do esôfago está freqüentemente associado a outros, sincrônicos ou metacrônicos tumores do trato aerodigestivo alto.

    Objective: To identify the risk factors of radiation-induced liver disease (RILD) after three-dimensional radiotherapy (3DCRT) for primary liver carcinoma (PLC) and the dosimetric threshold of RILD. Methods: Between April 1999 and August 2003, 128 PLC patients who were treated with 3DCRT received a mean dose of 53.6 ± 6.6 Gy with a 4-8 Gy/f, 3f/w, qod regimen. The relation between RILD and the possible clinical factors, such as gender, age, UICC/ AJCC T stage, GTV, HBV status, PTV, TACE, Child-Pugh grade of liver cirrhosis, BED calculated by LQ model and fraction size were analyzed. Among 84 patients who had full dose- volume histogram (DVH) data, the relation between RILD and dosimetric parameters were analyzed. Results: Nineteen patients (14.8%) developed RILD. It was found that T stage, GTV, PTV, Child-Pugh grade of liver cirrhosis and the acute hepatic toxicity proposed by common toxicity criteria version 2.0 (CTC2.0) were correlated with RILD (P=0.024, 0.002, 0.001, 0.000, 0.000, respectively). Multivariate analysis showed that only the Child-Pugh grade of liver cirrhosis was independent factor (P=0.000). The mean liver dose was significantly higher in patients with RILD (P=0.027). In patients with Child-Pugh grade A, V5 (percentage of normal liver volume with radiation dose > 5 Gy), V 10 and V 20 ≤81%, 69% and 42%, mean liver dose ≤28 Gy, RILD was not observed, whereas in patients with Child-Pugh grade B, the possibility of developing RILD was 53.3%(8/15). Conclusions: Comprehensive consideration of T stage, GTV, PTV and Child-Pugh grade of liver cirrhosis, especially the Child-Pugh grade of liver cirrhosis, when planning 3DCRT for PLC, may lower the incidence of RILD.

    Full Text Available Background : Mexico′s National Institute of Respiratory Diseases (NIRD is a third-level national reference center. Primary adenoid cystic carcinoma (PACC is an uncommon neoplastic disorder; hence improvements in the description of this disease are needed. Materials and Methods: This is a retrospective clinical study based on all consecutive patients with pathological diagnoses of PACC seen at the NIRD between January 1, 2000 and December 31, 2009. Results: We identified 9 cases of PACC (67% female out of a total of 2,634 patients with lung cancer seen during the period analyzed. The mean age of those 9 patients was 41 years (IQR 36-57, and the frequency of PACC at our center was 0.3%. It is important to note that 67% of those patients had a history of smoking and that 6 of the 9 had the antecedent of previous exposure to biomass fuel smoke. Baseline arterial blood gas analyses revealed a median of 61 mmHg for pO 2 and 28.5 mmHg for pCO 2 . Median FVC was 78%, while FEV 1 was 77% with an FEV 1 /FVC ratio of 78. Death occurred in 56% of cases, and the median survival time was 17 months (IQR 6-26 after the initial diagnosis. Conclusions: The frequency of tracheobronchial PACC among patients with lung cancer was similar to that previously reported (0.3%. According to our results, lung function has no specific phenotype in this disease; however, some abnormalities could be related to potential risk factors such as tobacco use and exposure to biomass fuel smoke.

    The prognostic significance of pathological response of primary tumor and metastatic axillary lymph nodes after neoadjuvant chemotherapy was assessed in patients with noninflammatory locally advanced breast carcinoma. Between January 1989 and April 1995, 148 consecutive patients with locally advanced breast carcinoma participated in the study. Of these, 140 fully evaluable patients (67, stage IIIA; 73, stage IIIB) were treated with three courses of 5-fluorouracil, doxorubicin, and cyclophosphamide (FAC), followed by modified radical mastectomy when technically feasible or definitive radiation therapy. The median age was 53 years (range, 26 to 75 years); 55% of patients were postmenopausal. Objective response was recorded in 99 of 140 patients (71%; 95% confidence interval, 63% to 79%). Complete response occurred in 11 patients (8%), and partial response occurred in 88 patients (63%). No change was recorded in 37 patients (26%), and progressive disease occurred in 4 patients (3%). One hundred and thirty-six patients underwent the planned surgery. Maximal pathological response of the primary tumor (in situ carcinoma or minimal microscopic residual tumor) was observed in 24 (18%); 112 patients (82%) presented minimal pathological response of the primary tumor (gross residual tumor). The number of metastatic axillary nodes after neoadjuvant chemotherapy was as follows: N0, 39 patients (29%); N1-N3, 35 patients (26%); > N3, 62 patients (45%). Considering the initial TNM status, 75% of the patients had decreases in tumor compartment after neoadjuvant chemotherapy. Also, 31% and 23% of patients with clinical N1 and N2, respectively, showed uninvolved axillary lymph nodes. A significant correlation was noted between pathological response of primary tumor and the number of metastatic axillary lymph nodes. Median disease-free survival was 34 months, whereas median overall survival was 66 months. Pathological responses of both primary tumor and metastatic axillary lymph nodes

    Gallium-67 scintigraphy is a commonly performed imaging modality in deteting pyrogenic lesions in cases of long-standing inexplainable fever. To re-evaluate the significance of gallium imaging in such cases, a retrospective review was made of 56 scans performed in febrile patients in whom sufficient clinical and laboratory findings were obtained. Gallium scans were true positive in 30 patients, false positive in 3, true negative in 19, and false negative in 4. In the group of true positive, local inflammatory lesions were detected in 23 patients with a final diagnosis of lung tuberculosis, urinary tract infection, and inflammatory joint disease. Abnormal gallium accumulation, as shown in the other 7 patients, provided clues to the diagnosis of generalized disorders, such as hematological malignancies (n=3), systemic autoimmune diseases (n=3), and severe infectious mononucleosis (n=one). In the group of false positive, gallium imaging revealed intestinal excretion of gallium in 2 patients and physiological pulmonary hilar accumulation in one. In the true negative group of 19 patients, fever of unknown origin was resolved spontaneously in 12 patients, and with antibiotics and corticosteroids in 2 and 5 patients, respectively. Four patients having false negative scans were finally diagnosed as having urinary tract infection (n=2), bacterial meningitis (n=one), and polyarteritis (n=one). Gallium imaging would remain the technique of choice in searching for origin of unknown fever. It may also be useful for early diagnosis of systemic disease, as well as focal inflammation. (N.K.)

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

    Incisional biopsy may not always provide a correct classification of histologic subtypes of basal cell carcinoma (BCC). High-frequency ultrasound (HFUS) imaging of the skin is useful for the diagnosis and management of this tumor. The main aim of this study was to compare the diagnostic value of HFUS compared with punch biopsy for the correct classification of histologic subtypes of primary BCC. We also analyzed the influence of tumor size and histologic subtype (single subtype vs. mixed) on the diagnostic yield of HFUS and punch biopsy. Retrospective observational study of primary BCCs treated by the Dermatology Department of Hospital Costa del Sol in Marbella, Spain, between october 2013 and may 2014. Surgical excision was preceded by HFUS imaging (Dermascan C © , 20-MHz linear probe) and a punch biopsy in all cases. We compared the overall diagnostic yield and accuracy (sensitivity, specificity, positive predictive value [PPV], and negative predictive value [NPV]) of HFUS and punch biopsy against the gold standard (excisional biopsy with serial sections) for overall and subgroup results. We studied 156 cases. The overall diagnostic yield was 73.7% for HFUS (sensitivity, 74.5%; specificity, 73%) and 79.9% for punch biopsy (sensitivity, 76%; specificity, 82%). In the subgroup analyses, HFUS had a PPV of 93.3% for superficial BCC (vs. 92% for punch biopsy). In the analysis by tumor size, HFUS achieved an overall diagnostic yield of 70.4% for tumors measuring 40mm 2 or less and 77.3% for larger tumors; the NPV was 82% in both size groups. Punch biopsy performed better in the diagnosis of small lesions (overall diagnostic yield of 86.4% for lesions ≤40mm 2 vs. 72.6% for lesions >40mm 2 ). HFUS imaging was particularly useful for ruling out infiltrating BCCs, diagnosing simple, superficial BCCs, and correctly classifying BCCs larger than 40mm 2 . Copyright © 2016 AEDV.

    BACKGROUND There is now evidence to support that some cases of high-grade serous papillary carcinoma arise from the fallopian tubes rather than the ovaries. Common symptoms at presentation include abdominal pain and swelling, vomiting, altered bowel habit and urinary symptoms. To our knowledge, this is the first case of serous papillary carcinoma presenting as a vaginal mass lesion. CASE REPORT A 41-year-old woman was referred to the Bnai-Zion Medical Center with the main complaint of irregular vaginal bleeding, vaginal mucous discharge, and suspected pelvic mass. Physical examination showed a soft, painless mass, measuring about 10 cm in diameter located mainly in the recto-vaginal septum, but not involving the uterus. Ultrasound examination showed no abnormal ovarian or uterine findings. Transvaginal biopsies of the mass showed a poorly differentiated serous papillary carcinoma of ovarian, tubal, or peritoneal origin. The physical examination and imaging findings strongly indicated an inoperable tumor, and the patient was treated with neoadjuvant (pre-surgical) chemotherapy. Pre-operative computed tomography (CT) imaging showed the partial involvement of the colon, and so surgical treatment included total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy, partial vaginectomy, anterior rectal resection, and lymph node dissection. Histopathology of the surgical specimens showed a poorly differentiated serous carcinoma originating from the fimbria of the right fallopian tube. CONCLUSIONS To the best of our knowledge, this is the first report to describe primary fallopian tube papillary serous carcinoma presenting as a vaginal mass. Therefore, physicians should be aware of this possible diagnosis.

    For a long time, badminton was considered to be only a slow and light game for children, a game that is played outdoors and is structurally undemanding.Today, it is not an unknown and unrecognised sport, especially after it was included into the Olympics Games in 1992. Badminton is one of the oldest sports in the world. It is suitable for all ages (for children and elderly equally), women and men and even handicapped persons. Beginners can start playing badminton matches early because the basics are learned quickly. As a recreational activity, badminton is very popular in Zagreb. In the last 10 years, a number of halls specialized for badminton or offering badminton as one of available sports activities have been opened in Zagreb. At present, there are over 70 professional playgrounds for training of top contestants but also for the citizens who can play recreational badminton.

    Squamous cell carcinoma of thyroid is an uncommon, very aggressive neoplasm, having a poor prognosis and poor response to chemotherapy and radiotherapy. Surgery is the initial treatment of choice, although it often presents as a widespread disease at the time of diagnosis, usually with cervical swelling that causes most of the symptoms due to local infiltration or metastasis. Local infiltration from adjacent tumour and metastatic disease needs to be excluded from other primary epidermoid carcinomas, in order to make a correct diagnosis. This also requires the typical cytokeratin pattern seen in histological studies. The case is presented of a 53 year-old man with a medical history of hepatocarcinoma, with a cervical hypermetabolic lesion detected in an 18 F-FDG PET/CT performed to exclude widespread disease. The follow-up of this lesion with this technique and its usefulness is also described. Copyright © 2017 Elsevier España, S.L.U. y SEMNIM. All rights reserved.

    Full Text Available Introduction. Intraabdominal abscesses are in 98-99% cases the result of secondary and only in 1-2% of primary peritonitis. They are easy and successfully diagnosed. Abdominal abscesses of unknown cause are extremely rare. Case Outline. The authors present a 68-year-old man, without significant data in past history, who suddenly developed epigastric pain, nausea, vomiting and leukocytosis which was treated with antibiotics resulting in the alleviation of complaints and reduction of white blood cells count. After five days ultrasonography showed incapsulated collection of dense fluid in the epigastrium confirmed by CT scan two days later. Upper endoscopy excluded ulcer and/or perforation of the stomach and duodenum. Under local anesthesia, through the upper part of the left rectal muscle, puncture followed by incision was done, and about 50 ml of dense pus was removed. Finger exploration of the cavity showed no foreign body within the cavity. Using drainage, the recovery was quick and uneventful. By preoperative and postoperative abdominal investigations no cause of the abscess was found. Two and a half years after surgery the patient remained symptom-free with normal clinical, laboratory and ultrasonographic findings. Conclusion. The authors presented an intraabdominal abscess of unknown cause that was successfully treated with antibiotics, percutaneous puncture and drainage under local anaesthesia. In spite of all diagnostic methods the cause of the abscess could not be found. Thus, such a possibility, although being rare, should be taken into account.

    The influence of family history, irradiation and anti-cancer drug (Mitomycin C) on the occurrence of multiple primary neoplasms was analysed using the person-year method in 1359 Japanese breast carcinoma patients. There were 111 multiple primary neoplasms, including bilaterl breast cancer, in 109 patients; the incidence rate was 0.0072 per person-year. The incidence rate in patients with a family history of cancer was 1.29 times higher than in those without. In the bilateral breast cancer group there was about a 3 times higher frequency of family history of breast cancer. Irradiation therapy raised the occurrence of multiple primary neoplasms 1.28 fold, and Mitomycin C (40 mg) had no effect on the occurrence of neoplasms during a 10-year observation period. (author)

    The distinction between primary and secondary ovarian tumors may be challenging for pathologists. The purpose of the present work was to develop genomic and transcriptomic tools to further refine the pathological diagnosis of ovarian tumors after a previous history of breast cancer. Sixteen paired breast-ovary tumors from patients with a former diagnosis of breast cancer were collected. The genomic profiles of paired tumors were analyzed using the Affymetrix GeneChip ® Mapping 50 K Xba Array or Genome-Wide Human SNP Array 6.0 (for one pair), and the data were normalized with ITALICS (ITerative and Alternative normaLIzation and Copy number calling for affymetrix Snp arrays) algorithm or Partek Genomic Suite, respectively. The transcriptome of paired samples was analyzed using Affymetrix GeneChip ® Human Genome U133 Plus 2.0 Arrays, and the data were normalized with gc-Robust Multi-array Average (gcRMA) algorithm. A hierarchical clustering of these samples was performed, combined with a dataset of well-identified primary and secondary ovarian tumors. In 12 of the 16 paired tumors analyzed, the comparison of genomic profiles confirmed the pathological diagnosis of primary ovarian tumor (n = 5) or metastasis of breast cancer (n = 7). Among four cases with uncertain pathological diagnosis, genomic profiles were clearly distinct between the ovarian and breast tumors in two pairs, thus indicating primary ovarian carcinomas, and showed common patterns in the two others, indicating metastases from breast cancer. In all pairs, the result of the transcriptomic analysis was concordant with that of the genomic analysis. In patients with ovarian carcinoma and a previous history of breast cancer, SNP array analysis can be used to distinguish primary and secondary ovarian tumors. Transcriptomic analysis may be used when primary breast tissue specimen is not available

    Here we report a case of successful treatment with combination chemotherapy of carboplatin(CBDCA)and paclitaxel for a patient undergoing hemodialysis(HD)with cancer of unknown primary, conducted by monitoring the observed AUC of ultrafilterable CBDCA. CBDCA was administered at a dose of 125 mg on day 1 in each course, an amount which had been calculated by the Calvert formula(GFR: 0, target AUC: 5). HD was started at a point in time one hour after the completion of each CBDCA administration, and performed for 5 hours in each course. Blood samples were collected during the first 3 courses of chemotherapy to measure the plasma concentration of free-platinum. The observed AUCs(o-AUC)of CBDCA in the first, second and third courses were 3. 03, 3. 44 and 3. 50mg·min/mL, respectively. The o-AUC in the first course was lower than that in the second course. The o-AUC in the second course was nearly equal to that in the third course, while each o-AUC was below the target AUC(t-AUC). Partial response was achieved after two courses of the CBDCA and paclitaxel combination chemotherapy, with adverse events of Grade 3 neutropenia and Grade 3 peripheral neuropathy observed in each course after the second course of chemotherapy. o-AUC of CBDCA administered to HD patients can not only be below t-AUC, as in this case, but also oppositely above t-AUC in cases with different doses of CBDCA or HD settings. Our results suggest that the monitoring of o-AUC of CBDCA is useful when practicing CBDCA-based chemotherapy safely and effectively in cancer patients undergoing HD.

  12. Different Response to Nivolumab in a Patient with Synchronous Double Primary Carcinomas of Hypopharyngeal Cancer and Non-Small-Cell Lung Cancer

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

    Multiple primaries in a single patient are uncommon, though not very rare. The existence of such cancers in two un-related, non-paired organs is even more un-common. Here, we present a case of 55 years old male who presented to us with a mucoepidermoid carcinoma of the parotid gland and was operated. Later on, he presented with a large cystic swelling in the pelvis which turned out to be pseudomyxoma peritonei. A review of slides and immunohistochemistry indicated it to be adenocarcinoma colon. He presented again with recurrent mucoepidermoid carcinoma of the parotid which was operated successfully with the use of myocutaneous flap for wound closure. He is currently undergoing chemotherapy. In order to establish a separate mono-clonal etiology of both tumours, immunohistochemistry was performed. To the best of our knowledge, carcinoma multiplex in the colon and the parotid has never been reported before. (author)

    Full Text Available Fibroblast growth factor receptor 3 (FGFR3 seems to play an inhibitory role in bone development, as activating mutations in the gene underlie disorders such as achondroplasia and thanatophoric dysplasia. Findings from multiple myeloma (MM indicate that FGFR3 also can act as an oncogene, and mutation of codon 249 in the fibroblast growth factor receptor 3 (FGFR3 gene was recently detected in 3/12 primary cervical carcinomas. We have analysed 91 cervical carcinomas for this specific S249C mutation using amplification created restriction site methodology (ACRS, and detected no mutations. Immunohistochemistry was performed on 73 of the tumours. Reduced protein staining was seen in 43 (58.8% samples. Six of the tumours (8.2% revealed increased protein staining compared with normal cervical tissue. These patients had a better prognosis than those with reduced or normal levels, although not statistically significant. This report weakens the hypothesis of FGFR3 as an oncogene of importance in cervical carcinomas.

    Transcatheter arterial chemoembolization (TACE) is one of the most commonly used therapeutic procedures for primary hepatocellular carcinoma (HCC). As an important and easily-available embolic agent, gelatin sponge (Gelfoam) particles have been constantly and widely employed in clinical practice. Various types of embolic agents have been continuously developed and effectively used in TACE for liver cancers. For recent years, great progress has been made in the clinical use of gelatin sponge particles, as the most traditional embolic agent, in the interventional therapeutic field for HCC. This article aims to make a comprehensive review about gelatin sponge. (authors)

    The natural history of metastatic melanoma involving lymph nodes, in the absence of a known primary site (cutaneous, ocular or mucosal) has, to date, been poorly defined; and the optimal management of this rare subtype of disease is therefore unclear. Melanomas of unknown primary site (MUP) are estimated to comprise between 3.7 and 6% of all melanomas (Anbari et al. in Cancer 79:1861-1821, 1997).

    The current paradigm of metastasis proposes that rare cells within primary tumors acquire metastatic capability via sequential mutations, suggesting that metastases are genetically dissimilar from their primary tumors. This study investigated the changes in the level of expression of a well-defined panel of cell proliferation, differentiation, and apoptosis markers between the primary colorectal cancer (CRC) and the corresponding synchronous lymph node (LN) metastasis from the same patients. DNA flow cytometry and immunostaining of p53, bcl-2, and c-myc were carried out on 36 cases of CRC radical resection specimens with their corresponding LN metastases. There was very low probability that the histological patterns of primary tumors and LN metastases are independent (p < 0.001). Metastatic tumors were significantly more diffusely positive for p53 than the primary tumors (p < 0.001). Conversely, primary tumors were significantly more diffusely positive for c-myc than metastatic tumors (p = 0.011). No significant difference was found between the LNs and the primary tumors in bcl-2 positivity (p = 0.538) and DNA aneuploidy (p = 0.35), with a tendency towards negative bcl-2 and less aneuploidy in LN metastases than primary tumors. In conclusion, LN metastatic colorectal carcinomas have a tendency of being less differentiated, with a higher incidence of diffuse p53 staining, lower incidence of bcl-2 staining, and less aneuploidy in comparison to their primary counterparts suggesting a more aggressive biological behavior, which could indicate the necessity for more aggressive adjuvant therapy.

    The purpose of this study was to evaluate a whole-organ perfusion protocol of the pancreas in patients with primary pancreas carcinoma and to analyse perfusion differences between normal and diseased pancreatic tissue. Thirty patients with primary pancreatic malignancy were imaged on a 320-slice CT unit. Twenty-nine cancers were histologically proven. CT data acquisition was started manually after contrast-material injection (8 ml/s, 350 mg iodine/ml) and dynamic density measurements in the right ventricle. After image registration, perfusion was determined with the gradient-relationship technique and volume regions-of-interest were defined for perfusion measurements. Contrast time-density curves and perfusion maps were generated. Statistical analysis was performed using the Kolmogorov-Smirnov test for analysis of normal distribution and Kruskal-Wallis test (nonparametric ANOVA) with Bonferroni correction for multiple stacked comparisons. In all 30 patients the entire pancreas was imaged, and registration could be completed in all cases. Perfusion of pancreatic carcinomas was significantly lower than of normal pancreatic tissue (P < 0.001) and could be visualized on colored perfusion maps. The 320-slice CT allows complete dynamic visualization of the pancreas and enables calculation of whole-organ perfusion maps. Perfusion imaging carries the potential to improve detection of pancreatic cancers due to the perfusion differences. (orig.)

    Full Text Available OBJECTIVE: To investigate the accuracy of preoperative computed tomography (CT, magnetic resonance (MR imaging and diffusion-weighted imaging with background body signal suppression (DWIBS in the prediction of nodal involvement in primary rectal carcinoma patients in the absence of tumor invasion into pelvic structures. METHODS AND MATERIALS: Fifty-two subjects with primary rectal cancer were preoperatively assessed by CT and MRI at 1.5 T with a phased-array coil. Preoperative lymph node staging with imaging modalities (CT, MRI, and DWIBS were compared with the final histological findings. RESULTS: The accuracy of CT, MRI, and DWIBS were 57.7%, 63.5%, and 40.4%. The accuracy of DWIBS with higher sensitivity and negative predictive value for evaluating primary rectal cancer patients was lower than that of CT and MRI. Nodal staging agreement between imaging and pathology was fairly strong for CT and MRI (Kappa value = 0.331 and 0.348, P<0.01 but was relatively weaker for DWIBS (Kappa value = 0.174, P<0.05. The accuracy was 57.7% and 59.6%, respectively, for CT and MRI when the lymph node border information was used as the criteria, and was 57.7% and 61.5%, respectively, for enhanced CT and MRI when the lymph node enhancement pattern was used as the criteria. CONCLUSION: MRI is more accurate than CT in predicting nodal involvement in primary rectal carcinoma patients in the absence of tumor invasion into pelvic structures. DWIBS has a great diagnostic value in differentiating small malignant from benign lymph nodes.

    It was in 1994 when published studies appear that evaluate the utility of the {sup 18}F-FDG PET in the patients with primary tumors of unknown origin (TOD); starting from then diverse studies that support the clinical utility of the study arise with {sup 18}F-FDG PET in the detection of the primary tumor. It is as well as it has been calculated that the study with {sup 18}F-FDG PET is able to detect the primary tumor in around 40% of the patients with negative results in the conventional diagnostic procedures. Until the moment, most of the studies published in relation to the primary tumors of unknown origin only evaluate the paper of the study with {sup 18}F-FDG PET, without including the image fusion technique PET/CT, which has demonstrated in diverse studies; in oncological scenarios different from the TOD, a superior diagnosis certainty.

Computed tomography revealed a mass in the right lobe of the thyroid gland, accompanied with right neck lymphadenectasis and airway deviation caused by tumor compression. Thyroid imaging suggested a thyroid malignant tumor and suspicious lymph node metastasis. Histologically, the tumor was characterized by the tumor cells arranged in small nests or trabeculae with an abundant extracellular mucoid matrix. The tumor cells formed diffuse invasion among thyroid follicles. In the peripheral regions, prominent signet-ring-cells formed a sheet-like structure and extended into the extrathyroidal fat tissue. The tumor cells were diffusely positive for thyroid transcription factor-1 (TTF-1 and PAX8, while they were focally positive for pan-cytokeratin (AE1/AE3 and weakly expressed thyroglobulin. Results: Based on the histological features and immunohistochemical profile, a diagnosis of primary mucinous carcinoma of the thyroid gland with signet-ring-cell differentiation was rendered.Conclusion: Using a panel of immunohistochemical markers may be helpful for differential diagnosis and for determining whether the tumor is primary or not.

    The purpose of our study is to compare oncologic and functional outcomes of p16-positive oropharyngeal squamous cell carcinoma (OPSCC) patients, in the presence and absence of planned radiation to the primary bed following transoral surgery (TOS), stratified by T-classification. Retrospective cohort study of 261, T1-T4, consecutively TOS-treated OPSCC patients. At a median follow-up of 61months, local recurrence (LR) occurred in 6 (2.3%)patients (3 each in T1-T2 and T3-T4 groups), of which 5 had tumors in the tongue base and one in the tonsil. Of patients not receiving planned primary bed radiation, LR occurred in 3% of T1-T2s versus 17% of T3-T4s. In patients with T1-T2 tumors, Absolute Risk Reduction of LR with primary bed radiation was 3.26% (95% CI: -0.37%, 7%); Number Needed to Treat to prevent one LR was 31 (95% CI: 14.5, 271). Absolute Risk Increase for gastrostomy-tube with primary bed radiation was 34.4% (95% CI: 24%, 45%); Number Needed to Harm was 3 (95% CI: 2.2, 4.2), i.e., for every three patients with T1-T2 tumors receiving primary bed radiation, one had a gastrostomy-tube. Elimination of primary bed radiation in margin-negative resected, T1-T2 p16-positive OPSCC was not associated with significant compromise of local control, and correlated with superior swallowing preservation, assessed using gastrostomy rate as a surrogate. Lack of primary bed radiation in T3-T4 tumors associated with significantly increased LR rates. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Fifty-five selected patients with previously untreated squamous cell carcinoma of the head and neck regions were studied in a randomized, prospective manner. The three treatment categories were primary radiation (Gp R), primary surgery (Gp S), and preoperative radiation of 4000 rads in four weeks (Gp R/S). The local control rates for the 44 evaluable patients with a two-year minimum followup were 24%, 39%, and 43%, respectively. Further treatment attempts in patients failing initial therapy yielded local control rates of 35%, 39%, and 43% for Gp R, Gp S, and Gp R/S, respectively. None of the local control rates nor the corresponding survival curves were significantly different at P < 0.10. However, the group sizes were sufficiently small that true differences might not have been detected. Postoperative complications were higher in the primary radiation failures subsequently operated upon compared to the primary surgery group (P = 0.07). A table is included in which the types of postoperative complications are listed and enumerated according to treatment regime

    In the experiments on the C57B1 mice the authors studied the effect of artificial hyperglycemia (AH), amputation of the extremities with tumors as well as combinations of these effects on the intensity of metastatic spreading of carcinoma RL-67 to the lungs. AH did not prove to intensify the process of metastatic spreading if it was conducted on the 1, 3, 5, 7, 9 and 11th days. The average number of metastases did not differ from that in the control group. AH which was conducted one day before amputation of the extremety with the tumor caused a more significant inhibition of metastatic spreading than a surgical intervention

    Full Text Available A 46-year-old man with severe back pain visited our hospital. Magnetic resonance imaging revealed extensive bone metastasis and rectal wall thickness. Colonoscopy revealed circumferential stenosis with edematous mucosa, suggesting colon cancer. However, histological findings of biopsy specimens revealed inflammatory cells but no malignant cells. The patient underwent endoscopic ultrasound, which demonstrated edematous wall thickness without destruction of the normal layer structure. After unsuccessful detection of neoplastic cells by boring biopsies, we performed endoscopic mucosal resection followed by boring biopsies that finally revealed signet ring cell carcinoma. Herein, we present a case and provide a review of the literature.

    Clear cell hidradenocarcinoma is a rare tumor of eccrine sweat gland origin that has a predilection for the head and neck. It has an indolent growth pattern and a higher incidence of regional and distant metastases. Metastasizing adnexal carcinomas are rare; thus, currently there is no uniform treatment guideline. We report a case of an 89-year-old female patient with clear cell hidradenocarcinoma manifesting in the right ear helix that metastasized to the right parotid gland who was treated by wide local excision and radiation therapy.

    We conducted a pilot study to prospectively evaluate the efficacy of PET/CT with 11 C-choline (choline PET/CT) for primary diagnosis and staging of urothelial carcinoma of the upper urinary tract (UUT-UC). Enrolled in this study were 16 patients (9 men, 7 women; age range 51 - 83 years, mean ± SD 69 ± 10.8 years) with suspected UUT-UC. The patients were examined by choline PET/CT, and 13 underwent laparoscopic nephroureterectomy and partial cystectomy. Lymphadenectomy and chemotherapy were also performed as necessary in some of the patients. Of the 16 patients, 12 were confirmed to have UUT-UC (7 renal pelvis carcinoma and 5 ureteral carcinoma), 1 had malignant lymphoma (ureter), 1 had IgG4-related disease (ureter), and 2 had other benign diseases (ureter). Of the 16 study patients, 13 showed definite choline uptake in urothelial lesions, and of these, 11 had UUT-UC, 1 had malignant lymphoma, and 1 had IgG4-related disease. Three patients without choline uptake comprised one with UUT-UC and two with benign diseases. Of the 12 patients with UUT-UC, 3 had distant metastases, 2 had metastases only in the regional lymph nodes, and 7 had no metastases. Distant metastases and metastases in the regional lymph nodes showed definite choline uptake. The outcome in patients with UUT-UC, which was evaluated 592 - 1,530 days after surgery, corresponded to the patient classification based on the presence or absence of metastases and locoregional or distant metastases. Choline uptake determined as SUVmax 10 min after administration was significantly higher than at 20 min in metastatic tumours of UUT-UC (p < 0.05), whereas there was no statistically significant difference between the SUVmax values at 10 and those at 20 min in primary tumours of UUT-UC. This study suggests that choline PET/CT is a promising tool for the primary diagnosis and staging of UUT-UC. (orig.)

    This study was done to evaluate the clinical feasibility of FDG-PET scan in patients with cervical carcinoma. PET-scans were performed in 74 patients with cervical carcinoma from March, 1998 to September, 1998. Fourteen cases were done at pretreatment period and sixty cases were done at post-treatment follow up period. In this study, the scans were obtained after bladder emptying by foley catheter insertion and diuretics to reduce the tracer activity in the bladder and improve the images of central lesions. We could find some incidental recurrent or metastatic lesions by FDG-PET scan (at pretreatment; 5 cases, at post-treatment; clinically no evidence of disease; 8 cases). FDG-PET scan had high sensitivity (100%) for central lesions and metastatic lymph nodes of cervical cancer but could not precisely define the anatomic location of the cancer and the sensitivity was not superior than MRI. Earlier detection of metastatic lymph nodes was superior than CT/MRI (sensitivity; 100 %) for metastatic lymph nodes. Also we found 3 double primary cancers incidentally (2 lung cancers and 1 thyroid cancer). In conclusion, FDG-FET scan might be useful for the earlier of hidden lesions that cannot be detected by routine conventional methods and differential diagnosis with radiation fibrosis and benign lymph adenophy.

    Patients treated with intravesical bacillus Calmette-Guérin therapy for urothelial carcinoma often become refractory and experience recurrent disease, thus necessitating alternative intravesical treatment modalities if the patient is to be spared the morbidities associated with radical cystectomy. Intravesical treatment with taxane-based chemotherapy, such as docetaxel, has gained traction in urologic oncology, proving to be an effective salvage therapy in such patients. Systemic taxane-based chemotherapeutic regimens have long been used in several advanced malignancies, and their systemic side-effects and associated histologic correlates have been extensively documented. In contrast to adverse effects associated with systemic administration, intravesical taxane administration has thus far proven to be well-tolerated, with little to no systemic absorption. To our knowledge, features of taxane-induced systemic effects have not been reported in this setting. Herein, we report a case of a patient with recurrent urothelial carcinoma treated with intravesical docetaxel, along with primary cutaneous anaplastic large cell lymphoma, who developed characteristic dermatotoxic histologic findings associated with intravenous taxane administration. As such histopathologic findings often represent close mimickers of neoplastic and infectious etiologies, knowledge of the potential for systemic manifestations of taxane therapy in patients treated topically may prevent potentially costly diagnostic pitfalls. © 2018 John Wiley & Sons A/S.

    The efficacy of adjuvant radiochemotherapy (RCT) in patients with advanced stage head and neck carcinoma has been proven in prospective randomized trials. However, these trials focused on different head and neck sites. Specific analyses for treatment effects in squamous cell carcinoma of the oral cavity (OSCC) are missing. We evaluated our experiences with adjuvant concomitant RCT in advanced OSCC to compare the results with other treatment schemes using adjuvant RCT. A total of 183 patients with OSCC of UICC stages II-IVb were reviewed retrospectively. All patients were treated with radical surgery followed by adjuvant, conventional fractionated concomitant RCT using carboplatin. Overall survival was plotted by Kaplan-Meier analysis. Prognostic factors were identified through univariate and multivariate analysis. Univariate analysis showed a significant impact of T, N, and UICC stage, histopathologic grading, surgical margins, extracapsular spread (ECS), and lymphangiosis carcinomatosa on overall survival (Table 3). Patients with stage IVa had a higher 5-year overall survival rate (42.8%) than patients with stage IVb (25.0%) (Figure 1). The differences were significant in multivariate analysis (p = 0.033) (Table 4). Adjuvant concomitant RCT is an effective treatment in patients with advanced stage OSCC. However, it remains unclear, which patients should be treated with adjuvant RCT. For patients with stage IVb, adjuvant RCT yields poor results. Prospective randomized trials are needed to confirm which patients should be treated with adjuvant RCT. (orig.)

    Purpose: To assess the outcomes, toxicity, and quality of life (QOL) of patients with primary parotid carcinoma treated with surgery and postoperative radiotherapy at the Daniel den Hoed Cancer Center. Methods and Materials: Between 1995 and 2010, 186 patients with parotid carcinoma were treated with parotidectomy with or without neck dissection, followed by radiotherapy. Elective nodal irradiation (ENI) was applied to high-risk, node-negative disease. End points were locoregional control (LRC), disease-free survival (DFS), cause-specific survival (CSS), and overall survival (OS), late toxicity, and QOL. Results: After a median follow-up of 58 months (range, 4-172 months), the 5-year Kaplan-Meier estimates for LRC, DFS, CSS, and OS were 89%, 83%, 80%, and 68%, respectively. Forty-five events were reported: 24 distant metastases (DM) and 21 locoregional failures (LRF). Event-free survival rates by histological types were 89%, 78%, 76%, 74%, and 70% for acinic cell, mucoepidermoid, adenoid cystic, adenocarcinoma, and squamous cell carcinoma, respectively. More LRF were reported in patients with squamous cell and high-grade mucoepidermoid carcinoma (21% and 19%, respectively) than in patients with other histological types (p = 0.04) and more DM in patients with adenoid cystic and adenocarcinoma (20% and 19%, respectively) than in patients with other types (p = 0.03). None of the high-risk node-negative patients who received ENI developed regional failure. On multivariate analysis, T stage, N stage, grade, and presence of perineural invasion and facial paralysis correlated significantly with DFS. The 5-year cumulative incidence of grade {>=}2 late toxicity was 8%. QOL scores deteriorate during and shortly after treatment but returned in almost all scales to baseline scores within 6 months. Conclusions: Of the entire group, surgery and postoperative radiotherapy resulted in excellent outcomes with minimal side effects and preservation of good QOL scores. However, in

    To date, this is the first report to monitor changes of intratumor vascularization and the response to radiation and Cyberknife therapy in a patient with recurrent primary papillary serous carcinoma of the peritoneum by three dimensional (3D) power Doppler ultrasonography (PDUS). Transvaginal 3D PDUS detected a recurrent presacral tumor with abundant intratumor vascularity. Serial examinations of the tumor volume and serum CA-125 level were studied before, during, and 6 mo after therapy. Meanwhile, the intratumor blood flow was measured and expressed as vascularity indices. All of the tumor volume, intratumor vascularity indices and serum CA-125 level decreased progressively following therapy. A remaining lesion with nearly absent intratumor power Doppler signals suggested a scarring lesion posttreatment. Indeed, CT-guided tissue biopsy confirmed fibrotic change. 3D PDUS is useful to monitor the response to treatments and to differentiate residual tumors from lesions of scarring change posttreatment. It provides more accurate posttreatment information than pelvic computed tomography.

    Asthma is a very common disease, but primary tracheal tumors are extremely rare in children. Wheezing is not pathognomonic, but is the typical presentation of asthma and could also be found in patients with tracheal tumors. This report describes a 12-year-old boy with a previous history of frequent asthma attacks and experienced responses to antiasthma treatment. He was admitted to the hospital due to persistent wheezing and progressive dyspnea. Hyperinflation in the bilateral lungs was detected on chest x-ray, but without other significant findings. Chest computed tomography revealed a mass at the carina. Tracheal mucoepidermoid carcinoma was diagnosed by histopathological assessment. Despite the rarity of tracheal tumors, chest computed tomography scans should be performed in the first place for children presenting persistent wheezing and having poor response to antiasthma treatment to rul
