    Full Text Available The rarity of adrenocortical carcinoma prompted us to report a case who came with a history of swelling in the left flank associated with pain, weakness and loss of appetite. Ultrasonography revealed a left retroperitoneal mass which was removed by radical surgery along with the left kidney and spleen. On histopathological examination, a diagnosis of adrenocortical carcinoma was made. (Hough criteria score 2.97. The cells of the tumor were arranged in closely packed columns and cords supported by fibrovascular stroma. There was no evidence of metastasis.

The objectives of this study were to evaluate the efficacy and toxicity of cisplatin...

  3. Adrenocortical carcinoma in preoperative diagnostic

    International Nuclear Information System (INIS)

    Decisions concerning surgical treatment of patients with adrenocortical tumor without hormonal hyperactivity are based on tumor size exceeding 3-6 cm and morphological features of malignancy. The aim of the study was to analyze results of diagnostic imaging in patients with adrenocortical carcinoma (ACC). Results of diagnostic imaging of 8 patients in whom postoperative pathological examination revealed ACC were analyzed. There were 3 women and 5 men in the analyzed group, with an age range of 32 to 75 years. Imaging was based on US and CT examination supported by MRI in 2 patients. The obtained results were compared with a group of 10 patients with adrenocortical adenoma (ACA). Results are presented as median values and 95% CI. CT results of patients with ACC showed local spread into surrounding fat tissue in 87.5%, adjacent organ invasion in 75%, local lymph node enlargement in 75%, irregular tumor margins in 88%, and heterogeneous structure of all tumors. In patients with ACA, tumor heterogeneity was observed in 40% and local lymph node enlargement in 10%. ACC tumors were significantly larger than ACA ones [77 (66-97) vs. 31 (24-48) mm, respectively, p=0.0002] and more dense [60 (34-85) vs. 16 (10-26) HU, respectively, p=0.0007]. In arterial phase, enhancement of ACC tumors tended to be stronger compared with ACA [81 (29-162) vs. 55 (33-76), p=0.09]. On the basis of CT results, 1 patient was classified as stage II according to Mac Farlane, 6 as stage III, and 1 as stage IV. Intraoperative examination down-staged 2 patients from stage III to stage II. Computed tomography is a method that allows distinguishing adrenocortical adenoma from carcinoma as well as to determine the stage of adrenocortical carcinoma. (author)

    Adrenocortical carcinoma (ACC) is a tumor with poor prognosis and limited therapeutic options. Therefore, in addition to multi-chemotherapeutic regimens IGF-1 receptor (IGF-1R) targeting approaches have been evaluated including immunoliposomal (IL) preparations utilizing an IGF-1R inhibiting antibody. In the current study, we extended our experiments by long-term treatment regimens in the classical adrenocortical NCIH295R xenograft model as well as by short-term experiments in two novel xenograft models, which all displayed different levels of IGF-1R and IGF-2 expression. Interestingly, these experiments reveal sub-group dependent differences in therapeutic outcome, reflecting clinical observations and indicate, thus, that implementation of this panel of tumor models might be helpful for clinical translation of novel therapeutic regimens in the future.

    There is a paucity of literature describing and comparing the imaging features of adrenocortical adenomas and carcinomas in children and adolescents. To document the CT and MRI features of adrenocortical neoplasms in a pediatric population and to determine whether imaging findings (other than metastatic disease) can distinguish adenomas from carcinomas. We searched institutional medical records to identify pediatric patients with adrenocortical neoplasms. Pre-treatment CT and MRI examinations were reviewed by two radiologists in consensus, and pertinent imaging findings were documented. We also recorded relevant histopathological, demographic, clinical follow-up and survival data. We used the Student's t-test and Wilcoxon rank sum test to compare parametric and nonparametric continuous data, and the Fisher exact test to compare proportions. We used receiver operating characteristic (ROC) curve analyses to evaluate the diagnostic performances of tumor diameter and volume for discriminating carcinoma from adenoma. A P-value ≤0.05 was considered statistically significant. Among the adrenocortical lesions, 9 were adenomas, 15 were carcinomas, and 1 was of uncertain malignant potential. There were no differences in mean age, gender or sidedness between adenomas and carcinomas. Carcinomas were significantly larger than adenomas based on mean estimated volume (581 ml, range 16-2,101 vs. 54 ml, range 3-197 ml; P-value = 0.003; ROC area under the curve = 0.92) and mean maximum transverse plane diameter (9.9 cm, range 3.0-14.9 vs. 4.4 cm, range 1.9-8.2 cm; P-value = 0.0001; ROC area under the curve = 0.92). Carcinomas also were more heterogeneous than adenomas on post-contrast imaging (13/14 vs. 2/9; odds ratio [OR] = 45.5; P-value = 0.001). Six of 13 carcinomas and 1 of 8 adenomas contained calcification at CT (OR = 6.0; P-value = 0.17). Seven of 15 children with carcinomas exhibited metastatic disease at diagnosis, and three had inferior vena cava invasion. Median

    Full Text Available Adrenocortical carcinoma (ACC is a rare neoplasm with a slight predilection for female patients. We report two cases of ACC. The first case was of a 7-year-old girl who presented with clitoromegaly. The second case was of a 22-Year-old female who presented with a lump in the abdomen and features of Cushing′s syndrome with virilization.The clinical, biochemical, histological features along with differential diagnosis are discussed. These cases are presented because of their rarity, and also to highlight the importance of differentiating ACC from an adenoma particularly in pediatric patients.

    Full Text Available Adrenocortical carcinomas are rare tumors with an incidence of one to two cases per million population and are still more rarer in the pediatric age group. Adrenocortical carcinomas can be functional or may be unassociated with syndromes of hormone overproduction. It is very important to differentiate an adrenocortical adenoma from a carcinoma, as both share a large number of phenotypic features, and assess their prognosis, as adrenocortical carcinoma may need an adjuvant therapy. In this communication, we describe the case of a two-year-old boy, who presented with iso-sexual precocious puberty, having features of virilization, which included growth of facial and pubic hair, deepening of voice, and penile growth.

    Full Text Available Functioning adrenocortical carcinomas are rare diseases with dismal prognosis. A 41-year-old man presenting with gynecomastia had a giant feminizing adrenocortical carcinoma at stage IV. Although surgical resection was controversial, we removed the primary tumor to reduce the mass effects. He lived for 12 months with an acceptable quality of life. Gynecomastia may be the first sign of feminizing adrenal malignancies. Surgery may ameliorate the quality of life in selected patients with metastatic disease.

    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.

Androgen levels were increased and a pelvic sonogram revealed a suprarenal mass of the left kidney. The tumor was successfully removed. At 6 years 11 months, androgen levels increased again. Workup for tumor recurrence was negative and the findings likely represented early adrenarche. The patient had menarche at an appropriate time and attained a height appropriate for her family.

    Full Text Available We report the case of a 73-year-old man who presented with an asymptomatic hepatic mass during investigation of mild chronic obstructive pulmonary disease by a plain chest radiograph, followed by ultrasonography, which revealed a solitary hepatic lesion measuring 7.1 cm × 6.5 cm × 5.8 cm in dimension. Fine- needle aspiration of the mass revealed malignant cells compatible with hepatocellular carcinoma. Interestingly, the patient had a left adrenalectomy and complete left nephrectomy in 1987, for a non-functioning left adrenocortical carcinoma (ACC. The ACC was diagnosed as stage two, with no evidence of local invasion or distant metastases. No adjuvant therapy was recommended postoperatively. After a five-year follow-up, there was no evidence of ACC recurrence and the patient was declared cured from his ACC. The patient underwent a complete segmental resection of the right lobe of the liver successfully. The final diagnosis of the mass was a well-differentiated metastatic adrenocortical carcinoma.

    Adrenocortical carcinoma (ACC) in pediatric and adolescent patients is rare, and it is associated with various clinical symptoms. We introduce the case of an 8-year-old boy with ACC who presented with peripheral precocious puberty at his first visit. He displayed penis enlargement with pubic hair and facial acne. His serum adrenal androgen levels were elevated, and abdominal computed tomography revealed a right suprarenal mass. After complete surgical resection, the histological diagnosis was ACC. Two months after surgical removal of the mass, he subsequently developed central precocious puberty. He was treated with a gonadotropin-releasing hormone agonist to delay further pubertal progression. In patients with functioning ACC and surgical removal, clinical follow-up and hormonal marker examination for the secondary effects of excessive hormone secretion may be a useful option at least every 2 or 3 months after surgery.

    We describe a comprehensive genomic characterization of adrenocortical carcinoma (ACC). Using this dataset, we expand the catalogue of known ACC driver genes to include PRKAR1A, RPL22, TERF2, CCNE1, and NF1. Genome wide DNA copy-number analysis revealed frequent occurrence of massive DNA loss followed by whole-genome doubling (WGD), which was associated with aggressive clinical course, suggesting WGD is a hallmark of disease progression. Corroborating this hypothesis were increased TERT expression, decreased telomere length, and activation of cell-cycle programs. Integrated subtype analysis identified three ACC subtypes with distinct clinical outcome and molecular alterations which could be captured by a 68-CpG probe DNA-methylation signature, proposing a strategy for clinical stratification of patients based on molecular markers.

    Context: Adrenocortical carcinoma (ACC) is a rare endocrine malignancy with a poor prognosis. Although the majority of childhood ACC arises in the context of inherited cancer susceptibility syndromes, it remains less clear whether a hereditary tumor predisposition exists for the development of ACC in adults. Here, we report the first occurrence of familial ACC in a kindred with Lynch syndrome resulting from a pathogenic germline MSH2 mutation. Case: A 54-year-old female with a history of ovarian and colorectal malignancy was found to have an ACC. A detailed family history revealed her mother had died of ACC and her sister had previously been diagnosed with endometrial and colorectal cancers. A unifying diagnosis of Lynch syndrome was considered, and immunohistochemical analyses demonstrated loss of MSH2 and MSH6 expression in both AACs (proband and her mother) and in the endometrial carcinoma of her sister. Subsequent genetic screening confirmed the presence of a germline MSH2 mutation (resulting in deletions of exons 1–3) in the proband and her sister. Conclusion: Our findings provide strong support for the recent proposal that ACC should be considered a Lynch syndrome-associated tumor and included in the Amsterdam II clinical diagnostic criteria. We also suggest that screening for ACC should be considered in cancer surveillance strategies directed at individuals with germline mutations in DNA mismatch repair genes. PMID:27144940

    .1 grams was removed, which was encapsulated and lobulated. Tumour diameter was 3.5 cm. Histopathological examination showed focal necrosis. The tumour infltrated its capsule and sinusoidal invasion was present. 20 mitotic cells/10 high power fields were seen. Ki-67 proliferation index was %25. Vimentine, synaptophysin and melan-A were positive, chromogranin was focal positive and pancreatin was negative with immunohistochemical examination. The tumor met five of the criteria of Weiss used in histological diagnosis of adrenocortical carcinoma (number of mitosis, nuclear atypia, atypical mitosis, capsular invasion and sinusoidal invasion. Pathological diagnosis was adrenocortical carcinoma. There were no sign of adrenal insufficiency during and after the surgery. He did not take any treatment after surgery. Serum potassium and aldosterone returned to normal after adrenalectomy. His symptoms such as weakness and pain were also resolved. One year after adrenalectomy, the patient is alive, normotensive, normokalemic and with no signs of recurrence of the primary adrenal tumor (Table 1. In summary, we reported the case of a 32-year-old male who initially presented with hypertension and severe hypokalemia and was found to have an aldosterone-secreting adrenocortical carcinoma. Aldosterone-producing adrenocortical carcinom (APAC is a rare cause of hypertension often diagnosed late. Aldosterone hypersecretion often concurs with that of other steroids, including glucocorticoids, estrogens or androgens. In most cases clinical picture reveals classical signs of Conn’s syndrome; hypertension and hypokalemia. Weakness and diffuse muscular pain are common due to severe hypokalemia, but these symptoms are not useful in differentiating APAC from an aldosterone secreting adenoma or hyperplasia (5.

    function improved with intravenous hydration and anti-coagulation treatment. Unfortunately, the adrenal mass was unresectable because of the extent of the tumor. Treatment with mitotane, an adrenocorticolytic drug, was started with concomitant with irradiation of a lesion at T5, followed by combination chemotherapy thereafter. Conclusion Unilateral right-sided varicoceles are rare and should alert the clinician to possible underlying pathology causing inferior vena caval obstruction. Left-sided varicoceles, in contrast, are common secondary to the venous anatomy of the left testis; however, the enlargement of the left testicle can be associated with blockage of the left testicular vein by tumor invasion of the left renal vein. Varicoceles could be an early presentation of a non-functioning adrenocortical carcinoma. Acute kidney injury can occur as a result of mass effect or thrombosis of renal vessels. Large tumors can cause abdominal pain as a late manifestation. Physicians should perform a complete abdominal examination in every patient with varicocele or testicular pain.

    Histopathologic diagnosis of adrenocortical tumors is based on adverse features that indicate malignant potential. Proliferation index has served as a supplemental tool in assessing the malignant potential of adrenocortical tumors. None of the current histologic classification systems can sufficiently accurately predict tumors' metastatic potential. We studied 177 consecutive adult patients with primary adrenocortical tumors operated on at Helsinki University Central Hospital between 1990 and 2003, all patients with a minimum follow-up of 5 years. We determined for each tumor the Weiss score and the Weiss revisited score by Aubert. Proliferation index was measured by computer-assisted image analysis. Each of the 9 Weiss criteria and the proliferation index were then used to establish a scoring system to predict the metastatic potential of adrenocortical tumors. Use of stepwise regression analysis led us to propose a calculation: 3 × mitotic rate (>5/50 high-power fields) + 5 × presence of necrosis + proliferation index in the most proliferative area of the tumor. Using a cutoff value of 8.5, the new scoring system was able to diagnose metastatic adrenocortical carcinoma with 100% sensitivity (confidence interval [CI], 76.8%-100%) and 99.4% specificity (CI, 96.6%-100%). The corresponding sensitivity of the Weiss system was 100% (CI, 76.8%-100%), and specificity, 90.2% (CI, 84.6%-94.3%), with sensitivity of the Weiss revisited system at 100% (CI, 76.8%-100%) and specificity at 96.9% (CI, 93.0%-99.0%). The new Helsinki score thus was accurate in predicting the metastatic potential of adrenocortical tumors. PMID:25582500

    Full Text Available Multiple endocrine neoplasia-1 (MEN1 is an autosomal dominant syndrome with classic triad of parathyroid hyperplasia, pancreatic neuroendocrine tumors, and pituitary adenomas. Other recognized manifestations include carcinoid, cutaneous or adrenocortical tumors. It is commonly presented with clinical features related to parathyroid, pancreas or pituitary lesions. Here, we have presented a case that had virilization and biochemical Cushing′s syndrome due to adrenocortical carcinoma as presenting feature of MEN1. Cushing′s syndrome in MEN1 is an extremely rare and usually late manifestation and most cases are due to corticotropin-producing pituitary adenomas. Although Cushing′s syndrome generally develops years after the more typical manifestations of MEN1 appear, it may be the primary manifestation of MEN1 syndrome particularly when related to adrenal adenoma or carcinoma.

    Full Text Available Adrenocortical carcinoma (ACC is a rare malignancy and cytodiagnosis of this tumor is not routinely encountered by a cytopathologist. Here, we report a case of ACC initially diagnosed by computed tomography (CT-guided fine needle aspiration cytology (FNAC with the help of immunocytochemistry. A 48-year-old lady presented with flank pain and abdominal mass for the last 6 months. A CT scan of her abdomen revealed a large mass arising from the upper part of the left kidney. CT-guided FNAC was performed. Cytologic smears showed pleomorphic large cells arranged discretely and in small aggregates against a myxoid background. The cells had a high nucleocytoplasmic ratio, anisonucleosis and conspicuous nucleoli. Based on cytomorphology, differential diagnoses of ACC and renal cell carcinoma (RCC were made. On immunocytochemistry, the tumor cells were synaptophysin, inhibin, vimentin and Melan-A positive but cytokeratin and epithelial membrane antigen negative. Thus, a cytodiagnosis of myxoid ACC was made and histopathologic examination was suggested. Subsequent histologic examination and immunohistochemistry proved the case to be myxoid ACC.

    Full Text Available A 20-month-old female presented with respiratory distress and a right adrenal mass extending into the inferior vena cava and right atrium. The mass was initially thought to be neuroblastoma. Pathology later revealed adrenocortical carcinoma. Inferior vena cava extension is far more common in adrenocortical carcinoma than neuroblastoma, and its presence should prompt clinical and laboratory evaluation for an adrenocortical tumor. The genetic findings in TP53 associated with this disease are discussed.

    Full Text Available Adrenocortical carcinoma, a rare malignancy is a rare cause of Cushing’s syndrome. Open adrenalectomy, a preferred modality for its treatment has inherent problems of difficult surgical access, bleeding, massive blood transfusion, coagulation defect, pulmonary embolism, large fluid shifts, cardiovascular collapse and postoperative complications. Cushing syndrome also poses challenge to anaesthesiologist in perioperative period, due to presence of hyper-cortisolism, volume overload, hypertension, hyperglycemia, hypokalaemia, difficult airway and difficult ventilation. We report a case of Cushing’s syndrome due to adrenocortical carcinoma in 50 year old female, who was diagnosed by her clinical presentation, blood investigations and radiological reports. During open adrenalectomy, excessive bleeding had occurred as tumour had invaded inferior vena cava. This was successfully managed with crystalloids, colloids, whole blood, fresh frozen plasma, platelet transfusion and vasopressor support. Postoperative management in PACU included mechanical ventilation, anti-hypertensive and steroids. Inferior vena cava invasion by tumour was not there in earlier CT scan images. Inadvertent inferior vena cava invasion by tumour adds not only to surgical difficulty but also to the problems of anaesthesiologist in managing Cushing syndrome. For successful outcome one has to be prepared for such an un-anticipated problem.

    Full Text Available Abstract Background Adrenocortical carcinoma is a rare, highly malignant tumor. Cardiac involvement of the tumor is very rare. Echocardiography facilitates the evaluation of the cardiac involvement of the tumor. Case Presentation We describe a patient with an adrenal tumor. Transthoracic echo showed its extension into the right atrium. Accordingly, a combined abdominal and cardiac operation was performed, monitored by transesophageal echocardiography. Conclusion This case highlights the importance of echocardiography in revealing the cardiac involvement by this tumor and in planning the operative procedure.

    Full Text Available Abstract Background Adrenal cortex oncocytic carcinoma (AOC represents an exceptional pathological entity, since only 22 cases have been documented in the literature so far. Case presentation Our case concerns a 54-year-old man with past medical history of right adrenal excision with partial hepatectomy, due to an adrenocortical carcinoma. The patient was admitted in our hospital to undergo surgical resection of a left lung mass newly detected on chest Computed Tomography scan. The histological and immunohistochemical study revealed a metastatic AOC. Although the patient was given mitotane orally in adjuvant basis, he experienced relapse with multiple metastases in the thorax twice in the next year and was treated with consecutive resections. Two and a half years later, a right hip joint metastasis was found and concurrent chemoradiation was given. Finally, approximately five years post disease onset, the patient died due to massive metastatic disease. A thorough review of AOC and particularly all diagnostic difficulties are extensively stated. Conclusion Histological classification of adrenocortical oncocytic tumours has been so far a matter of debate. There is no officially established histological scoring system regarding these rare neoplasms and therefore many diagnostic difficulties occur for pathologists.

    Background Adrenocortical carcinoma (ACC) is a rare malignancy. The aim of this study was to determine the incidence and patterns of recurrence after curative-intent surgery for ACC. Methods Patients who underwent curative-intent resection for ACC between 1993 and 2014 were identified from 13 academic institutions participating in the United States ACC study group. Patients with metastasis or an R2 margin were excluded. Patterns and rates of recurrence were determined and classified as locoregional and distant recurrence. Results A total of 180 patients with a median age of 52 years (interquartile range 43–61) were identified. Most patients underwent open surgery (n = 111, 64.5 %) and had an R0 resection margin (n = 117, 75.0 %). At last followup, 116 patients (64.4 %) had experienced recurrence (locoregional only, n = 41, 36.3 %; distant only, n = 51, 45.1 %; locoregional and distant, n = 21, 18.6 %). Median time to recurrence was 18.8 months. Several factors were associated with locoregional recurrence, including left-sided ACC location (odds ratio [OR] 2.71, 95 % confidence interval [CI] 1.06–6.89) and T3/T4 disease (reference T1/T2, OR 3.04, 95 % CI 1.19–7.80) (both p prognosis.

  19. Phase I trial of systemic intravenous infusion of interleukin-13-Pseudomonas exotoxin in patients with metastatic adrenocortical carcinoma

    International Nuclear Information System (INIS)

    Adrenocortical carcinoma (ACC) is a rare but lethal malignancy without effective current therapy for metastatic disease. IL-13-PE is a recombinant cytotoxin consisting of human interleukin-13 (IL-13) and a truncated form of Pseudomonas exotoxin A (PE). The main objectives of this Phase I dose-escalation trial were to assess the maximum-tolerated dose (MTD), safety, and pharmacokinetics (PK) of IL-13-PE in patients with metastatic ACC. Eligible patients had confirmed IL-13 receptor alpha 2 (IL-13Rα2) expressions in their tumors. IL-13-PE at dose of 1–2 μg/kg was administered intravenously (IV) on day 1, 3, and 5 in a 4-week cycle. Six patients received 1 μg/kg and two patients received 2 μg/kg of IL-13-PE. Dose-limiting toxicity was observed at 2 μg/kg, at which patients exhibited thrombocytopenia and renal insufficiency without requiring dialysis. PK analysis demonstrated that at MTD, the mean maximum serum concentration (Cmax) of IL-13-PE was 21.0 ng/mL, and the terminal half-life of IL-13-PE was 30–39 min. Two (25%) of the eight patients had baseline neutralizing antibodies against PE. Three (75%) of the remaining four tested patients developed neutralizing antibodies against IL-13-PE within 14–28 days of initial treatment. Of the five patients treated at MTD and assessed for response, one patient had stable disease for 5.5 months before disease progression; the others progressed within 1–2 months. In conclusion, systemic IV administration of IL-13-PE is safe at 1 μg/kg. All tested patients developed high levels of neutralizing antibodies during IL-13-PE treatment. Use of strategies for immunodepletion before IL-13-PE treatment should be considered in future trials

  1. Determination by R/A of plasma cortisol levels as a parameter of adrenocortical function before and after radiotherapy of gynaecological genital carcinoma

    International Nuclear Information System (INIS)

    rn 20 female patients with carcinoma of the genitals, day profiles of cortisol were established and ACTH stimulation tests carried out directly after radiotherapy and 6 months later. Plasma concentrations of cortisol were determined in a RIA as parameters of the adrenocortical function. The assumption of a change in adrenocortical activity after radiotherapy of gynaecological genital carcinoma could not be validated. Instead, there was a typical diurnal rhythm of plasma cortisol, with a peak in the early morning hours and a decrease until midnight. The same applies to the ACTH stimulation tests: In all cases, plasma cortisol levels were elevated after intravenous application of ACTH. This means that the 1976 findings of Samundzham and Butsan could not be proved. Since adrenal functions were absolutely normal in the observed cases, the adynamic clinical picture of patients after radiotherapy, which is rather infrequent, cannot be explained as being due to an impaired adrenocortical function.

    Full Text Available Abstract Background Drug repurposing for cancer treatment is an emerging approach to discover clinically approved drugs that demonstrate antineoplastic effect. The effective therapeutics for patients with advanced adrenocortical carcinoma(ACC are greatly needed. The objective of this study was to identify and validate drugs with antineoplastic effect in ACC cells using a novel quantitative high-throughput drug screening (qHTS technique. Methods A quantitative high-throughput proliferation assay of 2,816 clinically approved drugs was performed in the NCI-H295R ACC cell line. We validated the antiproliferative effect of candidate compounds in NCI-H295R cells. Further validation was performed in 3-dimensional multicellular aggregates (MCA of NCI-H295R and SW-13 cell lines. Results We identified 79 active compounds against ACC cells; 21 had an efficacy ≥60% and IC50 50. Methotrexate inhibited growth and caused disintegration of MCA in both cell lines at concentrations well below the maximum serum level (10 to 100 fold of IC50. Pyrimethamine caused growth inhibition in both cell lines at 10 fold of IC50 concentration. Conclusions qHTS of previously approved compounds is an effective and efficient method to identify anticancer drugs for a rare cancer such as ACC. We have validated the antineoplastic effect of Bortezomib, ouabain, Methotrexate and pyrimethamine, which could be translated into clinical trials in patients with locally advanced and/or metastatic ACC.

  3. n-3 polyunsaturated fatty acids abrogate mTORC1/2 signaling and inhibit adrenocortical carcinoma growth in vitro and in vivo.

    n-3 polyunsaturated fatty acids (PUFAs) are essential for human health and have been reported to reduce the risk of cancer, inhibit the growth of various types of tumors both in vitro and in vivo, and affect adrenal function. However, their effects on adrenocortical carcinoma (ACC) are not known. In the present study, we demonstrated that docosahexenoic acid (DHA) inhibited ACC cell proliferation, colony formation and cell cycle progression, and promoted apoptosis. In addition, ectopic expression of fat-1, a desaturase that converts n-6 to n-3 PUFAs endogenously, also inhibited ACC cell proliferation. Moreover, supplementing n-3 PUFAs in the diet efficiently prevented ACC cell growth in xenograft models. Notably, implanted ACC cells were unable to grow in fat-1 transgenic severe combined immune deficiency mice. Further study revealed that exogenous and endogenous n-3 PUFAs efficiently suppressed both mTOR complex 1 (mTORC1) and mTORC2 signaling in ACC in vitro and in vivo. Taken together, our findings provide comprehensive preclinical evidence that n-3 PUFAs efficiently prevent ACC growth by inhibiting mTORC1/2, which may have important implications in the treatment of ACC.

    Full Text Available Abstract The incidence of adrenal involvement in MEN1 syndrome has been reported between 9 and 45%, while the incidence of adrenocortical carcinoma (ACC in MEN1 patients has been reported between 2.6 and 6%. In the literature data only unilateral development of ACCs in MEN1 patients has been reported. We report a 31 years-old female MEN1-patient, in whom hyperplasia of the parathyroid glands, prolactinoma, non functioning pancreatic endocrine carcinoma and functioning bilateral adrenal carcinomas were diagnosed. Interestingly, a not previously described in the literature data, novel germline mutation (p.E45V in exon 2 of MEN1 gene, was detected. The association of exon 2 mutation of the MEN1 gene with bilateral adrenal carcinomas in MEN1 syndrome, should be further investigated.

    Purpose: Adrenocortical carcinoma (ACC) is a rare malignancy known for high rates of local recurrence, though the benefit of postoperative radiation therapy (RT) has not been established. In this study of grossly resected ACC, we compare local control of patients treated with surgery followed by adjuvant RT to a matched cohort treated with surgery alone. Methods and Materials: We retrospectively identified patients with localized disease who underwent R0 or R1 resection followed by adjuvant RT. Only patients treated with RT at our institution were included. Matching to surgical controls was on the basis of stage, surgical margin status, tumor grade, and adjuvant mitotane. Results: From 1991 to 2011, 360 ACC patients were evaluated for ACC at the University of Michigan (Ann Arbor, MI). Twenty patients with localized disease received postoperative adjuvant RT. These were matched to 20 controls. There were no statistically significant differences between the groups with regard to stage, margins, grade, or mitotane. Median RT dose was 55 Gy (range, 45-60 Gy). Median follow-up was 34 months. Local recurrence occurred in 1 patient treated with RT, compared with 12 patients not treated with RT (P=.0005; hazard ratio [HR] 12.59; 95% confidence interval [CI] 1.62-97.88). However, recurrence-free survival was no different between the groups (P=.17; HR 1.52; 95% CI 0.67-3.45). Overall survival was also not significantly different (P=.13; HR 1.97; 95% CI 0.57-6.77), with 4 deaths in the RT group compared with 9 in the control group. Conclusions: Postoperative RT significantly improved local control compared with the use of surgery alone in this case-matched cohort analysis of grossly resected ACC patients. Although this retrospective series represents the largest study to date on adjuvant RT for ACC, its findings need to be prospectively confirmed.

    The efficacy and tolerability of a combination of vincristine, cisplatin, teniposide, and cyclophosphamide (OPEC) in 11 patients (median age, 45 yr) with recurrent and/or metastatic adrenocortical cancer (ACC) (seven functional and four nonfunctional) were evaluated. All patients received this regimen after the failure of streptozocin and o,p'-DDD (SO) combination therapy. The regimen comprised cyclophosphamide, 600 mg/m2, and vincristine, 1.5 mg/m2, maximum dose 2.0 mg (d 1); cisplatin, 100 mg/m2 (d 2) and teniposide, 150 mg/m2 (d 4). Cycles were repeated every 4 wk. One to eight cycles (median, six cycles) of OPEC were administered to each patient. The median duration of treatment was 6 mo. The overall 2-yr survival rate was 82% and the median survival since diagnosis was 44 mo while it was 21 mo since start of OPEC therapy. Responses were obtained in nine patients: partial response in two patients, and stable disease in seven patients. The median duration of response was 6.75 mo. A total of 60 cycles of chemotherapy were given to all patients; grade 1-2 toxicity occurred in 57 cycles, while grade 3 toxicity was observed only in two cycles, according to NCI's Common Toxicity Criteria. We conclude that the OPEC regimen may be considered in recurrent or metastatic ACC as a second-line medical treatment. However, the combination is accompanied by considerable side effects and dose modifications are necessary in order to be able to recommend the treatment. This regimen needs further evaluation compared with SO therapy preferably in a randomized multicenter trial. PMID:15299189

    Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy. Limited data are available about on value of {sup 18}F-FDG PET/CT in ACC. We evaluated the impact of PET/CT on the management of ACC. We performed a retrospective review in patients with ACC who had undergone PET/CT. The impact of PET/CT on the management plan was evaluated by comparing the findings on PET/CT to the findings on contrast-enhanced CT. The sensitivity, specificity, and accuracy of each form of imaging were calculated. The correlations between PET/CT parameters, including maximum standardized uptake value (SUV{sub max}), total lesion glycolysis, and decline in SUV{sub max} after chemotherapy, and clinical outcome were evaluated. Included in the analysis were 106 patients with 180 PET/CT scans. Of the 106 patients, 7 underwent PET/CT only for initial staging, 84 underwent PET/CT only for restaging, and 15 underwent PET/CT for both initial staging and restaging. PET/CT changed the management plan in 1 of 22 patients (5 %) at initial staging and 9 of 99 patients (9 %) at restaging. In 5 of the patients in whom PET/CT changed the management plan, PET/CT showed response to chemotherapy but contrast-enhanced CT showed stable disease. Sensitivity, specificity, and accuracy were 100 %, 100 %, and 100 % for PET/CT at initial staging; 92.6 %, 100 %, and 96.4 % for CT at initial staging; 98.4 %, 100 %, and 99.5 % for PET/CT at restaging; and 96.8 %, 98.6 %, and 98.0 % for CT at restaging, respectively. No PET/CT parameters were associated with survival at either initial diagnosis or recurrence. PET/CT findings could substantially change the management plan in a small proportion of patients with ACC. Although lesion detection was similar between PET/CT and CT, PET/CT may be preferred for chemotherapeutic response assessment because it may predict response before anatomic changes are detected on CT.

  9. Adrenocortical oncocytoma

    International Nuclear Information System (INIS)

    Adrenocortical oncocytoma is an exceedingly rare pathological variant of an adrenal neoplasm. The pathogenesis of oncocytic neoplasms is poorly understood. Females have been reported to be affected 2.5 times more frequently than males, and left-sided lesions are more common than those on right side. This case describes a 20 years old female with right lumbar pain. She found to have a right adrenal gland mass measuring about 6 x 5 cm. A computed tomogram showed hypodense mass lesion 6 x 4.2 cm involving right adrenal gland. Differential diagnosis of non-functional adrenal adenoma was made. A laparoscopic right adrenalectomy was performed using the 3-ports lateral transperitoneal approach. Histopathology showed adrenocortical oncocytoma of adrenal gland. (author)

  10. Adrenocortical tumors in children

    Directory of Open Access Journals (Sweden)

    R.C. Ribeiro

    2000-10-01

    Full Text Available Childhood adrenocortical tumors (ACT are rare. In the USA, only about 25 new cases occur each year. In Southern Brazil, however, approximately 10 times that many cases are diagnosed each year. Most cases occur in the contiguous states of São Paulo and Paraná. The cause of this higher rate has not been identified. Familial genetic predisposition to cancer (p53 mutations and selected genetic syndromes (Beckwith-Wiedemann syndrome have been associated with childhood ACT in general but not with the Brazilian counterpart. Most of the affected children are young girls with classic endocrine syndromes (virilizing and/or Cushing. Levels of urinary 17-ketosteroids and plasma dehydroepiandrosterone sulfate (DHEA-S, which are abnormal in approximately 90% of the cases, provide the pivotal clue to a diagnosis of ACT. Typical imaging findings of pediatric ACT consist of a large, well-defined suprarenal tumor containing calcifications with a thin capsule and central necrosis or hemorrhage. The pathologic classification of pediatric ACT is troublesome. Even an experienced pathologist can find it difficult to differentiate carcinoma from adenoma. Surgery is the single most important procedure in the successful treatment of ACT. The role of chemotherapy in the management of childhood ACT has not been established although occasional tumors are responsive to mitotane or cisplatin-containing regimens. Because of the heterogeneity and rarity of the disease, prognostic factors have been difficult to establish in pediatric ACT. Patients with incomplete tumor resection or with metastatic disease at diagnosis have a dismal prognosis. In patients with localized and completely resected tumors, the size of the tumor has predictive value. Patients with large tumors have a much higher relapse rate than those with small tumors.

    @@ Myxoid adrenocorticfal adenomas are extremely rare with only 24 cases reported.1-12 The first case was reported by Tang et al1 in 1979 which was diagnosed as a myxoid adrenocortical carcinoma. Nearly all the reports were of single case except Browen et al3 who described a group of 14 cases. We report here an additional case of myxoid adrenocortical adenoma with an immunohistochemical study of the tumor and discuss the diagnosis with reference to the current literature.

    Renal cell carcinoma presents several unique features, which distinguish it from other tumours. The increase in survival that has been described in patients with renal cell carcinoma following nephrectomy breaks a classical rule of oncology, which states that surgery of the primary tumour has no role in the treatment of patients with advanced disease. Together with melanoma, it is the only tumour in which immunomodulatory treatments with drugs such as interleukin-2 produces a clinical benefit...

    Adrenocortical carcinoma (ACC) is an aggressive malignancy, which lacks an effective systemic treatment. Abnormal activation of insulin-like growth factor receptor 1 (IGF1R) has been frequently observed. Preclinical studies demonstrated that pharmacological inhibition of IGF1R signaling in ACC has antiproliferative effects. A previous phase I trial with an IGF1R inhibitor has demonstrated biological activity against ACC. The objective of this study is to assess the efficacy of the combination of the IGF1R inhibitor cixutumumab (IMC-A12) in association with mitotane as a first-line treatment for advanced/metastatic ACC. We conducted a multicenter, randomized double-arm phase II trial in patients with irresectable recurrent/metastatic ACC. The original protocol included two treatment groups: IMC-A12 + mitotane and mitotane as a single agent, after an initial single-arm phase for safety evaluation with IMC-A12 + mitotane. IMC-A12 was dosed at 10 mg/kg intravenously every 2 weeks. The starting dose for mitotane was 2 g daily, subsequently adjusted according to serum levels/symptoms. The primary endpoint was progression-free survival (PFS) according to RECIST (Response Evaluation Criteria in Solid Tumors). This study was terminated before the randomization phase due to slow accrual and limited efficacy. Twenty patients (13 males, 7 females) with a median age of 50.2 years (range 21.9-79.6) were enrolled for the single-arm phase. Therapeutic effects were observed in 8/20 patients, including one partial response and seven stable diseases. The median PFS was 6 weeks (range 2.66-48). Toxic events included two grade 4 (hyperglycemia and hyponatremia) and one grade 5 (multiorgan failure). Although the regimen demonstrated activity in some patients, the relatively low therapeutic efficacy precluded further studies with this combination of drugs. PMID:24849545

    Shortly after treatment with the cytostatic combination of cisplatin and paclitaxel was generally accepted as the standard therapy for patients with epithelial ovarian carcinoma, many have come to regard the combination of carboplatin and paclitaxel as a better choice. The latter combination causes fewer side effects and may be used in the outpatient clinic. Conceivably, the carboplatin-paclitaxel scheme will shortly have to be adjusted again owing to results of current research. The intensive basic research of recent years, namely, is beginning to yield benefits for the therapeutic arsenal against ovarian carcinoma. Possibilities are inhibitors of the breakdown of extracellular matrix (such as marimastat) and inhibitors of signal transduction (such as trastuzumab). PMID:10578409

    Full Text Available Hepatocellular carcinoma (HCC is an epithelial tumor derived from hepatocytes; it accounts for 80% of all primary liver cancers and ranks globally as the fourth leading cause of cancer-related deaths. HCC treatment is a multidisciplinary and a multimodal task, with surgery in the form of liver resection and liver transplantation (LT representing the only potentially curative modality. However, there are variable opinions and discussions about applying these surgical options and using other supporting treatments. This article is a narrative review that includes articles published from 1984 to 2013 located by searching scientific databases such as PubMed, SCOPUS, and Elsevier, with the main keyword of hepatocellular carcinoma in addition to other keywords such as liver transplantation, liver resection, transarterial chemoembolization, portal vein embolization, bridging therapy, and downstaging. In this review, we focus mainly on the surgical treatment options offered for HCC, in order to illustrate the current relevant data available in the literature to help in applying these surgical options and to use other supporting treatment modalities when appropriate.

    External auditory canal (EAC) carcinomas are relatively rare conditions lack on established treatment strategy. We analyzed a treatment modalities and outcome in 32 cases of EAC squamous cell carcinoma treated between 1980 and 2008. Subjects-17 men and 15 women ranging from 33 to 92 years old (average: 66) were divided by Arriaga's tumor staging into 12 T1, 5 T2, 6 T3, and 9 T4. Survival was calculated by the Kaplan-Meier method. Disease-specific 5-year survival was 100% for T1, T2, 44% for T3, and 33% for T4. In contrast to 100% 5-year survival for T1+T2 cancer, the 5-year survival for T3+T4 cancer was 37% with high recurrence due to positive surgical margins. The first 22 years of the 29 years surveyed, we performed surgery mainly, and irradiation or chemotherapy was selected for early disease or cases with positive surgical margins as postoperative therapy. During the 22-years, 5-year survival with T3+T4 cancer was 20%. After we started superselective intra-arterial (IA) rapid infusion chemotherapy combined with radiotherapy in 2003, we achieved negative surgical margins for advanced disease, and 5-year survival for T3+T4 cancer rise to 80%.

    Full Text Available Hepatocellular carcinoma (HCC is the fifth most common cancer worldwide, and it is responsible for up to one million deaths annually. Although multiple risk factors for HCC have been identifi ed, and despite preventive measures, the incidence of HCC continues to rise to epidemiologic proportions in the United States. In general, tumor resection and orthotopic liver transplantation are the treatment with the best outcome; however, HCC is generally diagnosed late in its course when patients are not eligible for curative treatment options. HCC is a relatively Chemo-refractory tumor secondary to heterogeneity of the tumor and the high rate of multidrug resistant gene expression. There are no standard treatments for HCC, multiple palliative treatment modalities have been used for patients with unresectable disease. None of these modalities have shown any superiority; and the retrospective nature of these available data has confounded any reasonable conclusions. Different institutions use different treatment schema dependent on the center expertise. Sorafenib, a tyrosine kinase inhibitor, has recently demonstrated a survival advantage in metastatic HCC, and if approved by the FDA, might become the standard of care. In this article we will review the rationale behind the currently available treatment options for HCC.

    The last decade witnessed the emergence of genomics, a set of high-throughput molecular measurements in biological samples. These pan-genomic and agnostic approaches have revolutionized the molecular biology and genetics of malignant and benign tumors. These techniques have been applied successfully to adrenocortical tumors. Exome sequencing identified new major drivers in all tumor types, including KCNJ5, ATP1A1, ATP2B3 and CACNA1D mutations in aldosterone-producing adenomas (APA), PRKACA mutations in cortisol-producing adenomas (CPA), ARMC5 mutations in primary bilateral macronodular adrenocortical hyperplasia (PBMAH) and ZNRF3 mutations in adrenocortical carcinomas (ACC). Moreover, the various genomic approaches - including exome sequencing, transcriptome, miRNome, genome and methylome - converge into a single molecular classification of adrenocortical tumors. Especially for ACC, two main molecular groups have emerged, showing major differences in outcomes. These ACC groups differ by their gene expression profiles, but also by recurrent mutations and specific DNA hypermethylation patterns in the subgroup of poor outcome. The clinical impact of these findings is just starting. The main altered signaling pathways now become therapeutic targets. The molecular groups of diseases individualize robust subtypes within diseases such as APA, CPA, PBMAH and ACC. A revised nosology of adrenocortical tumors should impact the clinical research. Obvious consequences also include genetic counseling for the new genetic diseases such as ARMC5 mutations in PBMAH, and a better prognostication of ACC based on targeted measurements of a few discriminant molecular alterations. Identifying the main molecular groups of adrenocortical tumors by extensively gathering the molecular variations is a significant step forward towards precision medicine. PMID:26739091

    BACKGROUND: Hepatocellular carcinoma (HCC) is one of the most frequent primary malignant tumors in the world. Hepatic resection and liver transplantation are considered optimal for potential treatment of HCC. However, only 20%of HCCs can be surgically treated. And most of surgically-noneligible patients have to receive interventional managements including local ablation and transarterial chemoembolization (TACE). In this paper, we review the interventional treatments of HCC. DATA SOURCES:A literature search of PubMed database was conducted and research articles were reviewed. RESULTS: Percutaneous ethanol injection (PEI) is usually applied to small HCC for a complete necrosis. Radiofrequency ablation, an alternative to PEI, also causes tumor necrosis and needs fewer times of ablation. Other methods such as acetic acid injection, laser, microwave, etc have enriched local ablation for HCC. High intensity focus ultrasound (HIFU) is thought to be promising. TACE, another common modality, can improve the survival rate of patients with HCC. The newly developed embolic agents and adjuvant rAd-p53 gene therapy are well reported. CONCLUSIONS:Surgically-noneligible HCC can be treated with interventional procedures. Each method has its advantages and disadvantages. However, it is still pressing to develop ablative methods as well as new embolic agents for a better prognosis of HCC.

    2010-07-01

    Full Text Available Abstract Introduction Primary pigmented nodular adrenocortical disease is a rare cause of adrenocorticotropic hormone-independent Cushing's syndrome. We report an uncommon primary pigmented nodular adrenocortical disease case presenting with a unilateral adrenocortical nodule and provide a brief overview of the existing literature. Case presentation A 27-year-old Caucasian woman was admitted to our Department with adrenocorticotropic hormone-independent Cushing's syndrome. Its cause was initially considered a left adrenocortical adenoma based on computer tomography imaging. The patient underwent left laparoscopic adrenalectomy and histological examination revealed pigmented micronodular adrenal hyperplasia. Evaluation for the presence of Carney complex was negative. Six months later recurrence of hypercortisolism was documented and a right laparoscopic adrenalectomy was performed further establishing the diagnosis of primary pigmented nodular adrenocortical disease. After a nine-year follow-up there is no evidence of residual disease. Conclusions Even though primary pigmented nodular adrenocortical disease is a rare cause of Cushing's syndrome, it should be included in the differential diagnosis of adrenocorticotropic hormone-independent Cushing's syndrome, especially because adrenal imaging can be misleading mimicking other adrenocortical diseases. Bilateral laparoscopic adrenalectomy is the preferred treatment in these subjects.

    On the biological point, estrogen overproduction with or without increase in other adrenal hormones are the main abnormalities. Radiological examination usually shows the tumor, describes its limits and its eventual metastases. Adrenal and endocrine origins are confirmed by biochemical assessments and histology, but that one is unable to distinguish between benign and malignant tumors, except if metastases are already present. Immunostaining using anti-aromatase antibodies is the only tool that distinguishes FAT from other adrenocortical tumors. Abdominal surgery is the best and the first line treatment. For large tumors (≥10 cm, an open access is preferred to coeliosurgery, but for the small ones, or when the surgeon is experienced, endoscopic surgery seems to give excellent results. Surgery can be preceded by adrenolytic agents such as ortho paraprime dichloro diphenyl dichloroethane (Mitotane, ketoconazole or by aromatase inhibitors, but till now there is not any controlled study to compare the benefit of different drugs. New anti-estrogens can be used too, but their results need to be confirmed in malignant tumors resistant to classical chemotherapy and to conventional radiotherapy. Targeted therapy can be used too, as in other adrenocortical tumors, but the results need to be confirmed.

    OBJECTIVE To determine the ideal method of surgical preoperative treatment for perforation with esophageal carcinoma.METHODS 36 cases of perforation with esophageal carcinoma were treated surgically in this series.Perforations occurred into the right lung in14 cases ,the mediastinum in 17 cases and trachea in 5 cases.Open thoracic surgery was performed in 34 cases,in which the right thoracic approach using a 3-incision method was applied in 16 cases,and operation by stages in 15 cases.Of the 34 cases,retrosternal substitution of the esophagus with stomach or colon was performed in 26 cases.RESULTS Surgery was successful in 31 cases and operative death occurred in 3 cases.The postoperative follow up study was from 3~72months.Of these cases 15 wree alive at 7~12 months, 2 at 24 months,and 1 at 72 months. The results can be considered satisfactory.CONCLUSION The therapeutic results of surgical treatment of perforation with esophageal carcinoma were markedly superior to that of conventional conservative treatment. The authors suggest that surgical intervention without delay should be undertaken for patients having a perforation with carcinoma of the esophagus. A right thoracic approach with a 3-incision method (retrosternal replacement of esophagus with stomach or colon) or operation by stages is preferable.

  12. A black adrenocortical adenoma causing Cushing's syndrome not imaged by radiocholesterol scintigraphy

    International Nuclear Information System (INIS)

    In a 33-year-old female patient with left adrenal tumour and Cushing's syndrome, adrenocortical scintigraphy with radiocholesterol did not image the tumour nor the suppressed contralateral gland. Histology showed a black adrenocortical adenoma composed only of compact cells; there was no evidence of malignancy. This demonstrates that non-visualization of the adrenal glands in a patient with Cushing's syndrome is not invariably due to adrenal carcinoma. The literature on black adrenal adenomas causing Cushing's syndrome is reviewed. (orig.)

    International Nuclear Information System (INIS)

    Thiazolidinediones, specific peroxisome proliferator-activated receptor-γ (PPAR-γ) ligands, used in type-2 diabetes therapy, show favourable effects in several cancer cells. In this study we demonstrate that the growth of H295R and SW13 adrenocortical cancer cells is inhibited by rosiglitazone, a thiazolidinediones member, even though the mechanisms underlying this effect appeared to be cell-specific. Treatment with GW9662, a selective PPAR-γ-inhibitor, showed that rosiglitazone acts through both PPAR-γ-dependent and -independent mechanisms in H295R, while in SW13 cells the effect seems to be independent of PPAR-γ. H295R cells treated with rosiglitazone undergo an autophagic process, leading to morphological changes detectable by electron microscopy and an increased expression of specific proteins such as AMPKα and beclin-1. The autophagy seems to be independent of PPAR-γ activation and could be related to an increase in oxidative stress mediated by reactive oxygen species production with the disruption of the mitochondrial membrane potential, triggered by rosiglitazone. In SW13 cells, flow cytometry analysis showed an arrest in the G0/G1 phase of the cell cycle with a decrease of cyclin E and cdk2 activity, following the administration of rosiglitazone. Our data show the potential role of rosiglitazone in the therapeutic approach to adrenocortical carcinoma and indicate the molecular mechanisms at the base of its antiproliferative effects, which appear to be manifold and cell-specific in adrenocortical cancer lines.

    Polychlorinated biphenyls (PCB), synthetic, persistent organic pollutants (POP), are detected ubiquitously, in water, soil, air, and sediments, as well as in animals and humans. PCB are associated with range of adverse health effects, such as interference with the immune system and nervous system, reproductive abnormalities, fetotoxicity, carcinogenicity, and endocrine disruption. Our objective was to determine the effects of three structurally different PCB congeners, PCB118, PCB 126, and PCB 153, each at two concentrations, on the steroidogenic capacity and proteome of human adrenocortical carcinoma cell line cultures (H295R) . After 48 h of exposure, cell viability was monitored and estradiol, testosterone, cortisol and progesterone secretion measured to quantify steroidogenic capacity of the cells. Two-dimensional (2D) gel-based proteomics was used to screen for proteome alterations in H295R cells in response to the PCB. Exposure to PCB 118 increased estradiol and cortisol secretion, while exposure to PCB 153 elevated estradiol secretion. PCB 126 was the most potent congener, increasing estradiol, cortisol, and progesterone secretion in exposed H295R cells. Seventy-three of the 711 spots analyzed showed a significant difference in normalized spot volumes between controls (vehicle only) and at least one exposure group. Fourteen of these protein spots were identified by liquid chromatography with mass spectroscopy (LC-MS/MS). Exposure to three PCB congeners with different chemical structure perturbed steroidogenesis and protein expression in the H295R in vitro model. This study represents an initial analysis of the effects on proteins and hormones in the H295R cell model, and additional studies are required in order to obtain a more complete understanding of the pathways disturbed by PCB congeners in H295R cells. Overall, alterations in protein regulation and steroid hormone synthesis suggest that exposure to PCB disturbs several cellular processes, including

Radiotherapy is the primary treatment modality. The role of systemic therapy has become more prominent. Based on multiple phase III studies and meta-analyses, concurrent cisplatin-based chemoradiotherapy is the current standard of care for locally advanced disease (American Joint Committee on Cancer manual [7th edition] stages II–IVb. The reported failure-free survival rates from phase II trials are encouraging for induction + concurrent chemoradiotherapy. Data from ongoing phase III trials comparing induction + concurrent chemoradiotherapy with concurrent chemoradiotherapy will validate the results of these phase II studies. Intensity-modulated radiotherapy techniques are recommended if the resources are available. Locoregional control exceeding 90% and reduced xerostomia-related toxicities can now be achieved using intensity-modulated radiotherapy, although distant control remains the most pressing research problem. The promising results of targeted therapy and Epstein–Barr virus-specific immunotherapy from early clinical trials should be validated in phase III clinical trials. New technology, more effective and less toxic chemotherapy regimens, and targeted therapy offer new opportunities for treating nasopharyngeal carcinoma.Keywords: nasopharyngeal carcinoma, intensity-modulated radiotherapy, chemoradiotherapy, molecular targeted agents, immunotherapy, prognostic markers

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

  20. Analysis of adrenocortical tumours morphology as regards their structure and potential malignancy

    International Nuclear Information System (INIS)

    Introduction: A consequence of diagnosis of adrenocortical carcinoma (ACC) is introduction of pharmacological therapy, precise monitoring of the patients and in some cases re-operation. The aim of the study is to analyse morphology of adrenocortical tumours as regards their malignancy by use of criteria proposed by Weiss. Material and methods: 110 adrenocortical tumours in 107 patients were analysed (M 27.1%, F 72.9%; age 32 to 77 years, mean 55.2 ± 9.7). Conn syndrome was diagnosed in 16 patients (14.9%), Cushing syndrome in 12 (11.2%), and virilisation in 3 (2.8%). In 76 patients (71.0%) biochemical tests did not reveal hormonal hyperactivity of the tumour. Results: In routine histopathological examination ACC was diagnosed in 6 tumours (5.4%), adrenocortical adenoma (ACA) in 92 (83.6%) and adrenocortical hyperplasia in 12 (10.9%). Nuclear grade III or IV was observed in 8 tumours (7.3%), mitotic rate > 5/50 high power fields in 6 (5.4%), atypical mitoses in 5 (4.5%), clear cells constituting < 25% of the tumour in 10 (9.1%), diffuse architecture in 8 (7.3%), necrosis in 16 (14.5%), veins infiltration in 4 (3.6%), sinusoids infiltration in 7 (6.3%), and tumour capsule infiltration in 5 (4.5%). Among ACC tumours 4 - 9 features of malignancy were present, among ACA - 0 - 3 features. Statistical analysis revealed correlation between number of criteria proposed by Weiss and maximal tumour size (p < 0.05). Conclusion: The structure and cell arrangement in adrenocortical adenoma are heterogeneous. Application of criteria proposed by Weiss in histopathological examination of adrenocortical tumours can be useful in differentiating adrenocortical adenoma from carcinoma. (author)

  1. Review of Topical Treatment of Upper Tract Urothelial Carcinoma

    Full Text Available A select group of patients with upper tract urothelial carcinoma may be appropriate candidates for minimally invasive management. Organ-preserving endoscopic procedures may be appropriate for patients with an inability to tolerate major surgery, solitary kidney, bilateral disease, poor renal function, small tumor burden, low-grade disease, or carcinoma in situ. We review the published literature on the use of topical treatment for upper tract urothelial carcinoma and provide our approach to treatment in the office setting.

    Daily treatment of female rats with medroxyprogesterone acetate in aqueous suspension resulted in adrenocortical atrophy. The doses given were those used for oestrus synchronisation. Intramuscular injections of 2-0 mg medroxyprogesterone acetate were used to investigate the atrophic process. Adrenocortical involution was associated with extensive single cell deletion (apoptosis). It is suggested that theses changes were due to suppression of pituitary ACTH secretion. The cytological changes support the concept that single cell death plays an important role in organ remodelling. Biochemical determinations of DNA, RNA, protein and dry matter, and histological examination, did not reveal significant changes in the liver. PMID:560035

    From October 1982 to August 1984, 30 previously untreated patients with biopsy-proven carcinoma of the nasopharynx, stage III (26.5%) and stage IV (73.5%), received combined radiotherapy (6,000 to 7,000 cGy over a period of 7 to 7.5 weeks) and chemotherapy (mitomycin-C 10 mg/M2, IV; 5-fluorouracil 750 mg/M2, IV; and methotrexate 30 mg/M2, IV) concomitantly. There were 20 males and 10 females, with a median age of 40 years. Minimal follow-up duration was 24 months. Actuarial overall survival rate at 48 months was 49%. Complete local response was achieved in 75% of the patients, with 31% of the cases failing distantly. The complication rate was high and included severe mucositis, xerostomia, and septicemia (fatal in two cases). Despite high local disease control, survival rate did not increase. A randomized trial is urgently needed to establish whether or not combined treatment is of value in advanced carcinoma of the nasopharynx.

    2016-01-01

    Treatment of hepatocellular carcinoma (HCC) is guided by the tumour stage. The Barcelona clinical liver cancer (BCLC) score endorsed by the European Society of the Liver EASL divides patients into five prognostic categories, each with a distinct treatment indication. Hepatic resection, orthotopic liver transplantation and percutaneous local ablation are strongly indicated in accurately selected patients with very early (BCLC 0) and early stage (BCLC A) tumours providing a survival rate of between 50 and 75% at year five. In patients with a large tumour burden such as those with intermediate stage BCLC B, repeated treatments with transarterial chemoembolization (TACE) are advocated with clinical benefits (from 16 to 22 months). Survival may also improve in patients who are in poor condition or who do not respond to TACE and those with an advanced HCC (BCLC C), following oral therapy with the multikinase inhibitor, sorafenib. However, most recommendations are based on uncontrolled studies and expert opinions rather than well-designed controlled trials, and up to one-third of patients do not fit recommendations because of advanced age, the presence of significant comorbidities or a strategic location of the nodule. For these patients, treatment of HCC beyond guidelines is often advocated. PMID:26725909

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

  8. Effects of bisphenol A-related diphenylalkanes on vitellogenin production in male carp (Cyprinus carpio) hepatocytes and aromatase (CYP19) activity in human H295r adrenocortical carcinoma cells

    International Nuclear Information System (INIS)

    The present study investigated the effects of the known xenoestrogen bisphenol A (BPA) relative to eight BPA-related diphenylalkanes on estrogen receptor (ER)-mediated vitellogenin (vtg) production in hepatocytes from male carp (Cyprinus carpio), and on aromatase (CYP19) activity in the human adrenocortical H295R carcinoma cell line. Of the eight diphenylalkanes, only 4,4'-(hexafluoropropylidene)diphenol (BHF) and 2,2'-bis(4-hydroxy-3-methylphenyl)propane (BPRO) induced vtg, i.e., to a maximum of 3% to 4% (at 100 μM) compared with 8% for BPA relative to the maximum induction by 17β-estradiol (E2, 1 μM). Bisphenol A diglycidyl ether (BADGE) was a potent antagonist of vtg production with an IC50 of 5.5 μM, virtually 100% inhibition of vtg at 20 μM, and an inhibitive (IC50) potency about one-tenth that of the known ER antagonist tamoxifen (IC50, 0.6 μM). 2,2'-Diallyl bisphenol A, 4,4'-(1,4-phenylene-diisopropylidene)bisphenol, BPRO, and BHF were much less inhibitory with IC50 concentrations of 20-70 μM, and relative potencies of 0.03 and 0.009 with tamoxifen. Bisphenol ethoxylate showed no anti-estrogenicity (up to 100 μM), and 4,4'-isopropylidene-diphenol diacetate was only antagonistic at 100 μM. When comparing the (anti)estrogenic potencies of these bisphenol A analogues/diphenylalkanes, anti-estrogenicity occurred at lower concentrations than estrogenicity. 4,4'-Isopropylidenebis(2,6-dimethylphenol) (IC50, 2.0 μM) reduced E2-induced (EC50, 100 nM) vtg production due to concentration-dependent cytotoxicity as indicated by a parallel decrease in MTT activity and vtg, whereas the remaining diphenylalkanes did not cause any cytotoxicity relative to controls. None of the diphenylalkanes (up to 100 μM) induced EROD activity indicating that concentration-dependent, CYP1A enzyme-mediated metabolism of E2, or any Ah-receptor-mediated interaction with the ER, was not a likely explanation for the observed anti-estrogenic effects. At concentrations as great as 100

    Highlights: ► A method for isolation of adrenocortical mitochondria from the adrenal gland of rats is described. ► The purified isolated mitochondria show excellent morphological integrity. ► The properties of oxidative phosphorylation are excellent. ► The method increases the opportunity of direct analysis of adrenal mitochondria from small animals. -- Abstract: This report describes a relatively simple and reliable method for isolating adrenocortical mitochondria from rats in good, reasonably pure yield. These organelles, which heretofore have been unobtainable in isolated form from small laboratory animals, are now readily accessible. A high degree of mitochondrial purity is shown by the electron micrographs, as well as the structural integrity of each mitochondrion. That these organelles have retained their functional integrity is shown by their high respiratory control ratios. In general, the biochemical performance of these adrenal cortical mitochondria closely mirrors that of typical hepatic or cardiac mitochondria.

  15. Combined treatment of the hypopharyngeal carcinoma

    International Nuclear Information System (INIS)

    From 1978 through 1984, 120 patients with hypopharyngeal carcinomas were treated cooperatively by the University Hospitals of Erlangen, 114 out of these patients were men and 6 women. 96 patients (80%) suffered from cervical lymph node metastases, 91 (76%) were already in UICC stage IV. There were two cases with stage I, eight cases (7%) with stage II, and 19 cases (16%) with stage III. Among the 116 patients treated by causal therapy, 70 (60%) reached complete remission (CR), 34 (29.5%) partial remission (PR), and 12 (10.5%) were non-responders (NC, P). The cumulative survival at five years was 14% in 120 patients and 24% in 70 patients after CR. None of the patients with PR or NC survived more than two years. 111 patients were irradiated. Group 1: radiotherapy alone (41 patients), group 2: surgery and radiotherapy (47 patients), group 3: chemotherapy and radiotherapy (19 patients). The medium treatment period was 76, 107, and 141 days, respectively. The cumulative survival at five years was 3% in group 1, 28% in group 2, the survival at three years in group 3 was 14%. The results of postoperative radiotherapy, amounting to 36%, were better than the rate of 20% achieved by preoperative radiotherapy and surgery. A survival at five years of 46% was obtained after transoral microlaryngoscopic laser resection and postoperative irradiation, which was therefore superior to conventional operation techniques combined with radiotherapy (16%). Moreover, better functional and cosmetic results were achieved with this method. The prognosis is unfavorably influenced by a high stage, lymph node manifestations, and dedifferentiated tumor histology. (orig.)

  16. Brachytherapy as sole treatment modality in initial cervix carcinoma

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate brachytherapy as the only treatment modality in inoperable early cervix carcinoma patients (carcinoma in situ, IA and IBocc). In a retrospective analysis 36 patients were treated with intracavitary irradiation between 1984 and 1988 in the Radiotherapy Department of the National Institute of Neoplasmic Diseases. Distribution by stage was; carcinoma in situ: one patient (2,47%), IA: six patients (16,6%), IBooc: twenty-nine patients (80,7%). Histology revealed epidermoid carcinoma in all cases. Mean age 55 years (range: 32-78). Treatment consisted in: two intracavitary applications of Radium, for 120 hours each, with a month interval, in 30 patients (carcinoma in situ: one, IA: four, IBocc: twenty-five patients), two applications of 72 hours each, with 15 days interval in four patients (IA: one, IBocc: 3) and one single intracavitary radium application in two patients (IA and IBocc). Local control was complete in all carcinoma in situ and IA patients. Only 1 of 29 patients with IBocc stage failed to respond, in spite of having received two applications, this shows that local response is independent of the number of insertions. Incidence of complications was low, and resolved with medical treatment. One patient had rectal adenocarcinoma 3 years after treatment -it was considered as radio induced neoplasm, since time of appearance was more than two years and localization was within irradiated area. Two patients died form intercurrent diseases, one (IBocc) from persistent diseases. Two patients were lost to follow-up. Three years survival was: 100% for carcinoma in situ and IA 86,2% for IBocc. Five years survival was 80% for IA and IBocc. Brachytherapy as unique modality of treatment is highly effective in initial cervix carcinoma stages. (author). 41 refs., 14 tabs., 2 figs., 1 ill

    Full Text Available Cushing syndrome is rare in infancy and usually due to an adrenocortical tumor (ACT. We report an infant with Cushing syndrome due to adrenocortical carcinoma. The patient presented at six months of age with a three-month history of growth failure, rapid weight gain, acne, and irritability. Physical examination showed obesity, hypertension, and Cushingoid features. Biochemical evaluation showed very high serum cortisol, mildly elevated testosterone, and suppressed ACTH. Abdominal MRI revealed a heterogeneous right adrenal mass extending into the inferior vena cava. Evaluation for metastases was negative. The tumor was removed surgically en bloc. Pathologic examination demonstrated low mitotic rate, but capsular and vascular invasion. She received no adjuvant therapy. Her linear growth has improved and Cushingoid features resolved. Hormonal markers and quarterly PET scans have been negative for recurrence 24 months postoperatively. In conclusion, adrenocortical neoplasms in children are rare, but should be considered in the differential diagnosis of Cushing syndrome.

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

    Full Text Available The current standard of care for metastatic urothelial carcinoma (UC is cisplatin-based chemotherapy but treatment is generally not curative. Mechanisms of resistance to conventional cytotoxic regimens include tumor cell drug efflux pumps, intracellular anti-oxidants and enhanced anti-apoptotic signaling. Blockade of signaling pathways with small molecule tyrosine kinase inhibitors has produced dramatic responses in subsets of other cancers. Multiple potential signaling pathway targets are altered in UC. Blockade of the PI3K/Akt/mTOR pathway may prove efficacious because 21% have activating PI3K mutations and another 30% have PTEN inactivation (which leads to activation of this pathway. The fibroblast growth factor receptor 3 protein may be overactive in 50-60% and agents which block this pathway are under active development. Blockade of multiple other pathways including HER2 and aurora kinase also have potential efficacy. Anti-angiogenic and immunotherapy strategies are also under development in UC and are discussed in this review. Novel therapeutic approaches are needed in UC. We review the various strategies under development in this disease and discuss how best to evaluate and optimize their efficacy.

    Full Text Available Pain in carcinoma cervix is a multidimensional experience with sensory, affective and cognitive-evaluative components. Many patients do not receive adequate pain management because of a lack of proper assessment, misconceptions regarding the pharmacologic and non pharmacologic methods of pain management and failure to distinguish between different types of pain. In our audit pelvic and nodal recurrence were the commonest cause of pain presenting as as pelvic pain, [42%], lumbosacral plexopathy [40%] and abdominal pain [34%] [n = 30]. Pain on defaecation caused by rectal obstruction, and suprapubic pain due to pyometra can be relieved by colostomy and drainage. Very little literature is available on the pain syndromes associated with carcinoma cervix. The present article is a review of cancer and treatment related pains in carcinoma cervix.

An etiologic association between HBV infection and the development of HCC has been established. Hepatitis C virus is also proving an important predisposing factor for this malignancy, the use of minimally invasive Percutaneous ablative technique (e.g. Radiofrequency (RF and Microwave ablation (MW has gained great momentum and because of the drawbacks of RF ablation, several groups have successfully proved the efficacious nature of Microwave ablation in the treatment of hepatocellular carcinoma. Aim of the Work: The aim of this work is to highlight the role, the principles and the applications of percutaneous Microwave Ablation in Hepatocellular carcinoma. Methods: The studied group included 30 patients (25 men and 5 women with hepatocellular carcinoma. All patients underwent microwave ablation for the hepatocellular carcinoma. Results: The results of the procedures will be assessed as regarding sizeand enhancement of the lesion (s on triphasic CT abdomen before the procedure and at the follow up at one month as well as the Alpha fetoprotein levels. Conclusion: MWA technique represents a safe, fast and efficacious way to perform hepatic ablation in patients with HCC. Initial results are encouraging; however, longer follow-up is needed for further classification of our results.

    Endocrine neoplasia is the most common tumor type in domestic ferrets, especially in middle-aged to older ferrets. Islet cell tumors and adrenocortical tumors constitute the major types of endocrine neoplasms. Insulinoma is a tumor that produces and releases excessive amounts of insulin. Evaluation of fasted blood glucose levels provides a quick diagnostic assessment for the detection of insulinomas. Use of glucocorticoids, diazoxide, and diet modification are some of the medical treatment options for insulinomas. Adrenocortical neoplasia in ferrets usually overproduces one or more sex hormones. Sex hormones which can result in progressive alopecia, vulvar swelling in females, and prostagomegaly in males. Abdominal ultrasonography and sex hormone assays can be used to diagnose adrenocortical neoplasms. Drugs such as leuprolide acetate, deslorelin acetate, and the hormone melatonin can be used to treat adrenocortical neoplasms in ferrets when surgery is not an option. PMID:20682429

    With substantially increased survival after most paediatric cancers over the past decades have come the late sequelae of treatment. Of all late complications of treatment, second malignancies are generally considered to be the most serious. We report on a 20-year-old man with an oral squamous cell carcinoma 17 years after initial chemotherapy and irradiation for acute lymphoblastic leukaemia. Although occurrence of the oral malignancy in this patient could have been treatment-related, one should keep in mind that the occurrence of second tumours may also be based on a shared genetic aetiology.

Angiogenesis inhibitors have been shown to be very effective for the treatment of metastatic renal cancer cell. Axitinib is a third-generation inhibitor of vascular endothelial growth factor receptor and is currently being developed for the treatment of various malignancies. The pharmacokinetic properties of axitinib may have a selective therapeutic effect, with minimal adverse reactions and enhanced safety. In a large Phase III study of previously treated patients with metastatic renal cell carcinoma, axitinib achieved a longer progression-free survival than sorafenib with an acceptable safety profile and good quality of life. This review focuses on the pharmacology, pharmacokinetics, and clinical activity of axitinib in the current treatment of renal cell carcinoma. The role of axitinib in the adjuvant and/or neoadjuvant setting needs to be evaluated in further clinical trials.Keywords: axitinib, renal cell carcinoma, vascular endothelial growth factor receptor, angiogenesis

    Functioning adrenocortical oncocytoma is very rare neoplasm. It is usually nonfunctional and benign and incidentally detected. Generally, these tumors originate in the kidneys, thyroid, parathyroid, and salivary or pituitary glands; they have also been reported in other sites including choroid plexus, respiratory tract, and larynx. Histologically, they are characterized by cells with eosinophilic granular cytoplasm and numerous packed mitochondria. We reported a case of a 44-year-old female who presented with Cushing syndrome for hypersecretion of cortisol due to adrenocortical oncocytoma. Magnetic resonance of abdomen revealed a right adrenal mass. Laparoscopic adrenalectomy was performed and the tumor was pathologically confirmed as benign adrenocortical oncocytoma. After surgical treatment, Cushing's syndrome resolved. PMID:26989553

    Conclusion: We report two consecutive rare cases of adrenohepatic fusion in giant right adrenocortical carcinoma, not detectable by imaging, what has important implications for the surgical decision-making. As radical surgery is the best choice to offer a curative treatment, it has to be performed by a multidisciplinary well-assembled team, counting with endocrine and liver surgeons, and transplant surgeons in case of vena cava involvement, in order to maximize the disease-free survival.

  2. Curative treatment of oesophageal carcinoma: current options and future developments

    International Nuclear Information System (INIS)

    Since the 1980s major advances in surgery, radiotherapy and chemotherapy have established multimodal approaches as curative treatment options for oesophageal cancer. In addition the introduction of functional imaging modalities such as PET-CT created new opportunities for a more adequate patient selection and therapy response assessment. The majority of oesophageal carcinomas are represented by two histologies: squamous cell carcinoma and adenocarcinoma. In recent years an epidemiological shift towards the latter was observed. From a surgical point of view, adenocarcinomas, which are usually located in the distal third of the oesophagus, may be treated with a transhiatal resection, whereas squamous cell carcinomas, which are typically found in the middle and the upper third, require a transthoracic approach. Since overall survival after surgery alone is poor, multimodality approaches have been developed. At least for patients with locally advanced tumors, surgery alone can no longer be advocated as routine treatment. Nowadays, scientific interest is focused on tumor response to induction radiochemotherapy. A neoadjuvant approach includes the early and accurate assessment of clinical response, optimally performed by repeated PET-CT imaging and endoscopic ultrasound, which may permit early adaption of the therapeutic concept. Patients with SCC that show clinical response by PET CT are considered to have a better prognosis, regardless of whether surgery will be performed or not. In non-responding patients salvage surgery improves survival, especially if complete resection is achieved

El aumento de supervivencia observado en pacientes con carcinoma renal metastásico tras la realización de nefrectomía, rompe un concepto clásico de la oncología según el cual la extirpación del tumor primario en tumores avanzados carece de sentido. Junto con el melanoma, es el único tumor en el que tratamientos inmunomoduladores, como interleukina-2 producen un beneficio clínico al paciente. El tratamiento del cáncer renal metastásico con interleukina-2 intravenosa a dosis altas ha confirmado en estudios aleatorios que puede producir respuestas completas de muy larga duración, en la práctica equivalentes a la curación. Por último, el cáncer renal está siendo empleado como modelo clínico para demostrar la eficacia de múltiples tratamientos dirigidos frente a nuevas dianas. En la actualidad se están estudiando más de 30 nuevos fármacos como tratamiento del cáncer renal, habiendo sido el primer tumor en el que se ha demostrado el beneficio clínico del tratamiento con inhibidores de la angiogénesis. En este artículo se revisan los aspectos más relevantes sobre el cáncer renal, incluyendo epidemiología, factores pronósticos, presentación clínica; bases moleculares y el estado actual de desarrollo de varios de los múltiples fármacos que se están estudiando en esta enfermedad.Renal cell carcinoma presents several unique features, which distinguish it from other tumours. The increase in survival that has been described in patients with renal cell carcinoma following nephrectomy breaks a classical rule of oncology, which states that surgery of the primary tumour has no role in the treatment of patients with advanced disease.

    International Nuclear Information System (INIS)

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

  8. Silencing mutated β-catenin inhibits cell proliferation and stimulates apoptosis in the adrenocortical cancer cell line H295R.

    Directory of Open Access Journals (Sweden)

    Sébastien Gaujoux

    Full Text Available CONTEXT: Adrenocortical carcinoma (ACC is a rare and highly aggressive endocrine neoplasm, with limited therapeutic options. Activating β-catenin somatic mutations are found in ACC and have been associated with a poor clinical outcome. In fact, activation of the Wnt/β-catenin signaling pathway seems to play a major role in ACC aggressiveness, and might, thus, represent a promising therapeutic target. OBJECTIVE: Similar to patient tumor specimen the H295 cell line derived from an ACC harbors a natural activating β-catenin mutation. We herein assess the in vitro and in vivo effect of β-catenin inactivation using a doxycyclin (dox inducible shRNA plasmid in H295R adrenocortical cancer cells line (clone named shβ. RESULTS: Following dox treatment a profound reduction in β-catenin expression was detectable in shβ clones in comparison to control clones (Ctr. Accordingly, we observed a decrease in Wnt/βcatenin-dependent luciferase reporter activity as well as a decreased expression of AXIN2 representing an endogenous β-catenin target gene. Concomitantly, β-catenin silencing resulted in a decreased cell proliferation, cell cycle alterations with cell accumulation in the G1 phase and increased apoptosis in vitro. In vivo, on established tumor xenografts in athymic nude mice, 9 days of β-catenin silencing resulted in a significant reduction of CTNNB1 and AXIN2 expression. Moreover, continous β-catenin silencing, starting 3 days after tumor cell inoculation, was associated with a complete absence of tumor growth in the shβ group while tumors were present in all animals of the control group. CONCLUSION: In summary, these experiments provide evidences that Wnt/β-catenin pathway inhibition in ACC is a promising therapeutic target.

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

    International Nuclear Information System (INIS)

    PhotoDynamic Therapy with porphyrins has been known for a long time; however, in tumor therapy it has been used only over the last 15 years. The effectiveness of PDT stems from the interaction between the photosensitizing substance which is stored selectively in the tumor tissue and the light of a specific wave-length. This leads to the formation of singulet oxygen which induces non-thermal tissue necrosis. Among other things, PDT can be used as a curative treatment for patients with visible early-stage endobronchial carcinoma. (author). 4 refs

    Fifteen patients with inoperable squamous cell carcinoma of the vulva were treated with Bleomycin and irradiation. Only 2 patients were also treated with vulvectomy and bilateral lymphadenectomy 2 weeks later. One patient survived more than 4 years without signs of recurrence, another survived 2 1/2 years and 2 more 18 and 12 months respectively. The rest died less than 6 months after the treatment. Three patients developed signs of lung fibrosis. Bleomycin and irradiation may render a tumor operable, but in most cases this regime merely aims at palliation.

    Immunotherapy has long played a role in urothelial cancers with the use of bacille Calmette Guérin (BCG) being a mainstay in the treatment of nonmuscle invasive bladder cancer. Novel therapeutic approaches have not significantly impacted mortality in this population and so a renaissance in immunotherapy has resulted. This includes recombinant BCG, oncolytic viruses, monoclonal antibodies, vaccines, and adoptive T-cell therapy. Herein, we provide a review of the current state of the art and future therapies regarding immunotherapeutic strategies for urothelial carcinoma. PMID:27247630

  15. The role of adrenocortical scintigraphy in the evaluation of unilateral incidentally discovered adrenal and juxtaadrenal masses

    International Nuclear Information System (INIS)

    We reviewed the findings of adrenocortical scintigraphy with 131I-6-beta-iodomethyl-19-norcholesterol (NCL-6131I) of 39 patients to clarify its role in the evaluation of unilateral adrenal or juxtaadrenal masses incidentally discovered by CT, ultrasonography or plain radiography. Twenty-seven benign adrenal masses showed various scintigraphic findings (hot nodules: 12 silent adenomas, warm nodule: one solid mass, normal appearance: one cyst and 2 solid masses, diffuse decrease: each one; solid mass, myelolipoma, ganglioneuroma and calcified adrenal and partial or complete defect: each one; solid mass, myelolipoma and ganglioneuroma and 2 cysts and 2 pheochromocytomas); while a partial or complete defect was shown in a nonfunctioning carcinoma and 3 metastases and a complete defect or inhomogenous uptake without opposite adrenal visualization was shown in 2 patients with cortisol-producing carcinoma. Therefore a hot nodule and an inhomogenous uptake or complete defect with nonvisualization of the opposite adrenal are specific to a benign tumor and a corticol-producing carcinoma, respectively. The impaired tumor uptake of NCL-6-131I is a nonspecific finding. The scintigraphic findings of juxtaadrenal masses were normal in 4 and deviated adrenals in 2. Thus adrenocortical scintigraphy can identify silent adenomas and cortisol-producing carcinomas among the adrenal masses and may help to differentiate juxtaadrenal from adrenal masses. (author)

  16. Treatment results of pediatric nasopharyngeal carcinoma, NCI, Cairo University experience

    International Nuclear Information System (INIS)

    Investigate treatment outcome, prognostic factors and survival among selected group of Egyptian pediatric nasopharyngeal carcinoma patients. Patients and methods Thirty patients treated from non-metastatic nasopharyngeal carcinoma between 1997 and 2012 were retrospectively evaluated including: TNM staging, chemo-radiotherapy regimens. Survival analysis was done using Kaplan–Meier survival curves. Results Twenty-three males and 7 females (M:F 3.2:1) with median age of 14 years; 84% with stages III/IV. Neck node enlargement was reported in 90% (27/30). Induction chemotherapy followed by radiotherapy was implemented in 80% of patients. Mucositis (87%) was the commonest treatment related toxicity. Nineteen patients (63%) were in CR with a median FU of 69 months (range 24–160). Eleven patients had treatment local and distant failures (2 local, 7 distant and 2 local/distant) at a median FU of 24 and 34 months respectively. 5-year overall and event-free survival rates were 77% and 63% respectively. Prolonged OAP of RT ⩾ 50 days, Hb<11 g% and T4 stage affected EFS and OAS on UVA; while on MVA; prolonged OAP of RT ⩾ 50 days (ρ = 0.002) and T4 stage (ρ = 0.004) affected EFS and only Hb < 11 g% (ρ = 0.019) affected OAS. Late toxicity was reported in 70% of irradiated patients. Conclusion Radio-chemotherapy management for pediatric NPC resulted in comparable treatment outcomes with tolerable late effects. Response adapted radio-chemotherapy regimens in addition to the potential use of IMRT should be recommended to decrease treatment related side effects. Prolonged OAP of RT ⩾ 50 days and low Hb level were encountered as adverse prognostic factors; findings that need further investigation.

  17. Primary radiation therapy in the treatment of anal carcinoma

    International Nuclear Information System (INIS)

    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 N0 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

    2005-01-01

    Hepatocellular carcinoma (HCC) is one of the most common cancers in the world.Surgical resection has been considered the optimal treatment approach, but only a small proportion of patients are suitable candidates for surgery, and the relapse rate is high. Approaches to prevent recurrence, including chemoemboliza-tion before and adjuvant therapy after surgery, have proven to have a limited benefit;liver transplantation is successful in treating limited-stage HCC because only a minority of patients qualify for transplantation. Therefore, new therapeutic strategies are urgently needed. Because in addition to the classical genetic mechanisms of deletion or inactivating point mutations, epigenetic alterations, such as hyperacetylation of the chromatin-associated histones (responsible for gene silencing), are believed to be involved in the development and progression of HCC, novel compounds endowed with a histone deacetylase (HDAC) inhibitory activity are an attractive therapeutic approach. In particular, pre-clinical results obtained using HA-But, an HDAC inhibitor in which butyric acid residues are esterified to a hyaluronic acid backbone and characterized by a high affinity for the membrane receptor CD44, indicated that this class of compounds may represent a promising approach for hepatocellular carcinoma treatment.

  20. Three cases of temporal bone osteoradionecrosis after nasopharyngeal carcinoma treatment

    International Nuclear Information System (INIS)

    Osteoradionecrosis is most commonly caused by radiation-induced injury. We report on 3 cases of temporal bone necrosis that occurred after chemoradiotherapy for nasopharyngeal carcinoma performed more than 10 years previously. Case 1 was a 42-year-old woman who had nasopharyngeal carcinoma in 1991. The patient underwent chemoradiotherapy (70 Gy total) in 1991, and gamma knife irradiation (20 Gy) in 1998 for local recurrence. The bone in the posterior wall of the left external auditory canal began to be exposed in 2003. Otorrhea from the left ear increased and we found a skin defect and ulcer formation in the postauricular region. We performed radical mastoidectomy and debridement on April, 2010. The area of the defect was covered and filled in with a pedicle musculoperiosteal flap. The intra-aural skin became dry in 6 months, however, she lost consciousness due to a temporal lobe abscess and underwent an emergency operation on April, 2011. After operation, the patient recovered with no neurological symptoms and infections up to the present date. Case 2 was a 58-year-old man who had nasopharyngeal carcinoma in 2001. The patient underwent chemoradiotherapy (66 Gy total) in 2001, and X knife irradiation (15 Gy) 3 months later due to the remaining tumor. The left posterior ear canal wall collapsed and the tympanic membrane retracted with pooling epithelial debris appearing in 2007. Left facial nerve palsy was seen in December 2010. We performed a mastoidectomy on January, 2011. Cholesteatoma and necrotic granuloma with fragile bone filled the mastoid cavity, and a facial canal bone defect was seen. Bone necrosis with cholesteatoma and inflammatory granuloma was revealed by the pathological examination. The facial palsy improved after the operation. Case 3 was a 59-year-old man who had left abducens palsy with nasopharyngeal carcinoma invading the clivus. The patient underwent chemoradiotherapy (60 Gy total) in 2001, and X knife irradiation (24 Gy) 4 months later for

    Full Text Available A small percentage of patients with hepatocellular carcinoma (HCC are candidates for curative treatment in form of resection or transplantation. There are different treatment options for unresectable HCC-like local ablative therapies and recently systemic therapy with Sorafenib. All of these have variable response rate and had been proven to improve survival. In the last few years, there is a growing interest in TheraSphere radioembolization. It consists of yttrium90 (Y-90 embedded into nonbiodegradable glass microspheres. It is selectively administered by intraarterial hepatic injection giving high doses of radiation to the tumor and sparing the liver parenchyma. It has been shown to improve survival and used as a bridge to transplantation and to downstage tumors for resection. Therasphere seems to have favorable safety profile and has been used in patients with portal vein thrombosis with successful outcome.

    The risk of developing renal cell carcinoma (RCC) increases with age, and given the constant gain in life expectancy of the general population, both localized RCC and metastatic RCC (mRCC) are more frequently observed in the elderly population. The elderly are a heterogeneous group of patients often characterized by the presence of comorbidities, different compliance to treatment and polypharmacy. Here we review the available data with the aim to analyze the safety and efficacy of new targeted therapies (TTs) in elderly mRCC patients. TTs seem to be effective in both older and younger patients, but elderly patients appear to show reduced tolerance to treatments compared to younger patients. Prospective trials are needed to better understand how to manage mRCC in elderly patients. PMID:26654225

  6. Carcinoma of the endometrium-prognostic factors and treatment decisions

    International Nuclear Information System (INIS)

    PURPOSE: Carcinoma of the endometrium is the most common gynecological malignancy in the U.S. As the treatment for endometrial cancer has evolved, FIGO has modified the staging three times over the past 25 years This course will review current staging, prognostic factors, treatment options, rationale and management strategies for patients with endometrial carcinoma. The data regarding local control and survival, and the ongoing clinical trials and controversies will be discussed in depth. MATERIALS AND METHODS: Despite the continued controversy regarding the true contribution of extensive surgical staging, the standard treatment for operable patients is total abdominal hysterectomy-bilateral salpingoopherectomy with regional lymph node staging. Various combinations of surgery and radiation have been used in the past, but the precise role of radiation as an adjuvant treatment is not well defined due to lack of well conducted randomized trials. With better knowledge and understanding of the natural history of the disease and significance of prognostic factors, three different risk groups have been identified; low risk, intermediate risk, high risk. Postoperative radiation has been shown to decrease local failures and improve survival in the majority of the intermediate risk group and high risk group of patients. Considerable experience has been accumulated in the use of High Dose Rate fractionated intravaginal treatment, and it probably has a very broad application in optimizing local control, with minimal morbidity. A stage-specific treatment algorithm, including critical pathways for the management of early and advanced endometrial cancer will be presented. RESULTS: As is evident from the long-term published data, the results of combined surgery and radiation treatment have been very satisfactory with minimal complications. CONCLUSION: A thorough assessment of the clinical and surgicopatho-logic prognostic parameters, in the context of the natural history of the

  7. Ethmoid sinus carcinomas: natural history and treatment results

    International Nuclear Information System (INIS)

    Purpose: This retrospective study was undertaken to assess the clinical features and results of treatment of carcinomas of the ethmoid sinus. Materials and methods: The records of 34 patients with ethmoid sinus carcinomas treated with curative intent at the U.T.M.D. Anderson Cancer Center (UTMDACC) between January 1969 and December 1993 were reviewed. The age of the patients ranged from 28 to 73 years with a median of 57 years. There were 28 Whites, four Hispanics, one Black and one Asian. A simple staging based on anatomical criteria was used to describe the extent of the disease. Six patients had T1, 13 patients had T2 and 15 patients had T3 disease. Twenty-one patients were treated with surgery plus radiation and 13 patients were treated with radiotherapy alone; nine patients received adjuvant chemotherapy. Radiation was given at ∼2 Gy per fraction to total doses of 50 Gy preoperatively, 52-66 Gy (median 60 Gy) postoperatively and 50-70 Gy (median 63 Gy) when no surgery was performed. Results: The actuarial 5-year overall, disease-free and disease-specific survival rates were 55%, 58% and 63%, respectively. The actuarial 5-year local control rate was 71% for the whole group (74% for surgery plus radiation and 64% for radiation alone). Local recurrence occurred in nine patients, nodal relapse occurred in three patients and distant metastases occurred in four patients. Histologically proven dura mater invasion was associated with a poorer local control rate in patients undergoing surgery and radiation. The simple T-staging system used in this study was a good discriminator for local control. Of nine patients receiving chemotherapy, three had complete responses and four had partial responses; six of the seven responders had undifferentiated carcinoma. Severe complications of therapy occurred in patients treated between 1969 and 1984 and consisted mainly of visual impairment and brain necrosis. Conclusions: This retrospective review of a large single institutional

  8. Advanced supraglottic carcinoma: a comparative study of sequential treatment policies

    International Nuclear Information System (INIS)

    Data from 131 consecutive patients with operable stage III or IV (American Joint Committee) supraglottic carcinoma were analyzed. Based on existing treatment policies at the time of presentation, patients received either preoperative radiation therapy (RT) (48 patients), surgery alone (42 patients), or postoperative RT (41 patients). Preoperative RT dose levels were either 2000 rad in five fractions (33 patients) or 5000 rad in 25 fractions (15 patients). Postoperative RT dosages were 5000 to 6000 rad in 6 to 6 1/2 weeks. Surgical procedures included either subtotal or total laryngectomy and radical neck dissection. Tumor control was achieved in 21 of 42 patients (50%) treated with surgery alone, 23 of 48 patients (48%) treated with preoperative RT, and 29 of 41 patients (71%) treated with postoperative RT (P . 0.005). The actuarial, recurrence-free survival at 5 years was 36% and 35%, respectively, in the surgery alone or preoperative RT groups as compared to 55% in postoperatively irradiated patients. The authors conclude that advanced but resectable supraglottic carcinomas may be best treated with surgery followed by RT, rather than with surgery alone or with combined preoperative RT and surgery

    Full Text Available Daniel E Spratt, Nancy LeeDepartment of Radiation Oncology, Memorial Sloan-Kettering Cancer Center, New York, NY, USAAbstract: In this article, we focus on the current and emerging treatments in nasopharyngeal cancer (NPC. A detailed evolution of the current standard of care, and new techniques and treatment options will be reviewed. Intergroup 0099 established the role for chemoradiotherapy (chemo-RT in the treatment of nasopharyngeal carcinoma. Multiple randomized Phase III trials have shown the benefit of chemo-RT; however, none of these studies utilized modern radiotherapy (RT techniques of intensity-modulated radiation therapy (IMRT. IMRT has the ability to deliver high doses of radiation to the target structures while sparing adjacent bystander healthy tissues, and has now become the preferred RT treatment modality. Chemotherapy also has had a shifting paradigm of induction and/or adjuvant chemotherapy combined with RT alone, to the investigation with concurrent chemo-RT. New treatment options including targeted monoclonal antibodies and small molecule tyrosine kinase inhibitors are being studied in NPC. These new biologic therapies have promising in vitro activity for NPC, and emerging clinical studies are beginning to define their role. RT continues to expand its capabilities, and since IMRT and particle therapy, specifically intensity-modulated proton therapy (IMPT, has reports of impressive dosimetric efficacy in-silica. Adaptive RT is attempting to reduce toxicity while maintaining treatment efficacy, and the clinical results are still in their youth. Lastly, Epstein–Barr virus (EBV DNA has recently been studied for prediction of tumor response and its use as a biomarker is increasingly promising to aid in early detection as well as supplementing the current staging system. RT with or without chemotherapy remains the standard of care for nasopharyngeal carcinoma. Advances in RT technique, timing of chemotherapy, biologically

    International Nuclear Information System (INIS)

    A patient with bilateral adrenal hyperplasia, due to the ectopic adrenocorticotrophic hormone (ACTH) syndrome, received a 3-month course of treatment with 1,1 dichloro-2(o-chlorophenyl)-2-(p-chlorophenyl)ethane (o,p' DDD), which caused adrenal hypofunction requiring steroid therapy. Eleven months later, Cushing's syndrome recurred. His CT scan showed a left adrenal gland that was enlarged and a normal-sized right adrenal gland. However, the NP-59 image showed increased uptake by both glands. Venous effluent was sampled from each adrenal vein. The plasma cortisol level from the left gland was 1392 ng/ml, and that from the right gland was 667 ng/ml. The latter value was not significantly different from the values obtained at peripheral sites (517-744 ng/ml). In the course of recovery from o,p' DDD damage, the ability of the adrenal gland to take up NP-59 may be restored before the return of its biosynthetic and secretory functions. Serial NP-59 adrenal images can anticipate the recurrence of Cushing's syndrome after adrenolytic therapy, thereby permitting early retreatment

    The pathologic diagnosis of adrenocortical carcinoma (ACC) still needs to be improved, because the renowned Weiss Score (WS) system has a poor reproducibility of some parameters and is difficult to apply in borderline cases and in ACC variants. The "reticulin algorithm" (RA) defines malignancy through an altered reticulin framework associated with 1 of the 3 following parameter: necrosis, high mitotic rate, and vascular invasion. This study aimed at validating the interobserver reproducibility of reticulin stain evaluation in an unpublished series of 245 adrenocortical tumors (61 adenomas and 184 carcinomas) from 5 Italian centers, classified according to the WS. Eight pathologists reviewed all reticulin-stained slides. After training, a second round of evaluation on discordant cases was performed 10 weeks later. The RA reclassified 67 cases (27%) as adenomas, including 44 with no reticulin alterations and 23 with an altered reticulin framework but lacking the subsequent parameters of the triad. The other 178 cases (73%) were carcinomas according to the above-mentioned criteria. A complete (8/8 pathologists) interobserver agreement was reached in 75% of cases (κ=0.702), irrespective of case derivation, pathologists' experience, and histologic variants, and was further improved when only those cases with high WS and clinically malignant behavior were considered. After the training, the overall agreement increased to 86%. We conclude that reticulin staining is a reliable technique and an easy-to-interpret system in adrenocortical tumors; moreover, it has a high interobserver reproducibility, which supports the notion of using such a method in the proposed 2-step RA approach for ACC diagnosis.

  12. Intraluminal brachytherapy in the treatment of bile duct carcinoma

    International Nuclear Information System (INIS)

    Patients with carcinoma of the biliary tract have a poor prognosis because the disease is often unresectable at diagnosis. Intraluminal brachytherapy has been reported as an effective treatment for localized cholangiocarcinoma of the biliary tract. The purpose of our study was to analyse the survival of patients treated with brachytherapy and make some recommendations regarding its use. Fifteen patients underwent brachytherapy via a trans-hepatic approach at the Royal Prince Alfred Hospital from 1983 to 1993. Eleven patients had low-dose rate brachytherapy and four patients had high-dose rate treatment. There were nine males and six females. The median age was 64 years. Other treatment included bypass procedures in two patients, endoscopic stents in 14 patients and external beam irradiation in one patient. The median survival was 12.5 months and 47% of the patients survived 1 year. The only complication reported was cholangitis which was seen in one patient. There did not seem to be any difference in survival or complications between low- and high-dose rate brachytherapy. It is concluded that the addition of intraluminal brachytherapy after biliary drainage prolongs survival and is a safe and effective treatment, but patients still have a high rate of local failure, and further studies will be needed to address this problem.

  13. The present approach to treatment of renal cell carcinoma

    International Nuclear Information System (INIS)

    Until the turn of the millennium, metastatic renal cell carcinoma (mRCC) was regarded as one of the most refractory cancers; highly resistant to both radiation and systemic therapy, and only small group of patients responded to immune modulation. Involved targeted therapies, which influence specific signal transduction pathways of tumor formation and progression, opened new options of treatment to give patients a new hope. After the first experiences with the new biologic agents we can claim, that these patients have improved a quality of life, provided stabilization of disease and prolong life of patients, but the cure is not available. However, there are so many studies with target therapies in RCC, but the most correct algorithm of treatment does not exist. Targeted therapies rarely achieve remission, prevailing a stabilisation of disease so patients have to undergo chronic treatment. In choice of optimal treatment is necessary to regard for quality of life, so usually the winner is the drug with the lowest toxic potential. (author)

  14. Treatment of hepatocellular carcinoma: A single-center experience

    International Nuclear Information System (INIS)

    Purpose. The comparative efficacy of transcatheter arterial chemoembolization (TACE) and percutaneous ethanol injection (PEI) in the treatment of hepatocellular carcinoma (HCC) was investigated. Methods. Two hundred and sixty consecutive patients were retrospectively analyzed: 156 had received between one and six chemoembolization sessions at 3-month intervals, 33 had had PEI, and the remaining 71 patients refused any treatment. The follow-up ranged from 3 to 36 months. Survival rates were statistically analyzed by life-table analysis. Results. Patients' survival was affected by the number of nodules and by the Child's and Okuda's classes; no relationship was found between survival rates and the histologic grade or vascular supply of the tumor. In the case of a single lesion of Okuda's class I, TACE was more effective than PEI. In multifocal HCC, TACE was better than no treatment in Okuda's class I and Child's class A. Conclusion. We suggest TACE as the treatment of choice in Child A or Okuda I patients with multifocal HCCs; it seems of little help in Child B-C or Okuda II-III patients

    Full Text Available We report a case of hepatocellular carcinoma (HCC that caused a severe arterioportal shunt (APS. A 49-year-old man was admitted to hospital due to esophagogastric variceal hemorrhage and HCC, and underwent endoscopic variceal ligation (EVL and endoscopic injection sclerotherapy (EIS. He was then referred to our hospital. Abdominal computed tomography revealed a low-density lesion in the posterior segment of the liver and an intratumoral APS, which caused portal hypertension. Although the patient underwent EVL, EIS, Hassab’s operation, and transcatheter arterial embolization for APS, he vomited blood due to rupture of esophagogastric varices. Right hepatectomy was performed for the treatment of HCC and APS, although the indocyanine green retention value at 15 min after intravenous injection was poor (30%. The patient’s postoperative course was uneventful. Eventually, APS disappeared and the esophagogastric varices improved.

    Radiotherapy is used to treat a wide variety of head and neck tumours that arise in and around the skull base. The delayed effects of radiation damages a range of structures, including the nervous system, bone, major vessels, mucus membranes, pituitary and salivary glands, as well as increasing the risk of radiation-induced neoplasms. In this review the complications resulting from radiation treatment for nasopharyngeal carcinoma (NPC), a cancer treated with a high dose of radiation to a fairly large region, are illustrated. Many patients with NPC have a long-term survival, so are at risk of developing delayed radiation effects, and hence may demonstrate a wide range of complications on imaging. Other tumours around the skull base treated with radiotherapy include meningiomas, chordomas, chondrosarcomas, pituitary adenomas, paranasal sinus and nasal cavity tumours. In these cases similar complications may be encountered on imaging, although the severity, incidence and location will vary.

    International Nuclear Information System (INIS)

    Forty-nine patients with squamous cell carcinoma of the floor of the mouth were studied retrospectively. The age of patients ranged from 30 to 84 years, with a mean age of 56 years. Treatment methods were interstitial brachytherapy alone or combined interstitial brachytherapy and external irradiation in cases without lymph node involvement. Cases in which lymph nodes were involved were treated by irradiation alone or combined irradiation and neck dissection. Some cases were treated by combined irradiation and radical resection. Two-and 5-year overall survival rates were 73.5% and 51.3%. Two-and 5-year cause-specific survival rates were 85.5% and 80.0%. Second primary cancers were observed in 10 cases (20.4%). T-factor, stage, and tumor size were significant prognostic indicators. (author)

    The incidence of primary cancer has been increasing globally and now-a-days it constitutes the 5th most frequent cancer of humans representing around 5% of all cancers worldwide. Chronic HBV infection assumes greater significance because of its reported association with cirrhosis, and more ominously hepatocellular carcinoma or HCC. Hepatitis B infection constitutes a major global problem with nearly 400 million infected individuals. It contributes to a significant degree of morbidity on account of the associated chronicity that develops in 5-10% of infected adults and more than 90% of infected neonates. Globally, around one million people suffering from HBVrelated chronic heptatitis and HCC die per year. Despite the availability of an effective prophylactic vaccine against hepatitis B for over 20 years, effective treatment of the chronic disease and associated HCC remains elusive. Therefore, identification of the cellular mediators and effectors of HCC is an important medical objective for developing new diagnostic tools and therapeutic strategies against it. Molecular biomarkers hold great promise for refining our ability to establish early diagnosis and prognosis for HCC, and to predict response to therapy. Proteomics is a rapidly expanding discipline that is expected to change the way in which disease can be diagnosed, treated and monitored in the near future. The proteomic analysis of serum and tumors should allow accurate prediction of what is happening at the protein level in a cancer cell or a body fluid proteome. It is the hope that, by deciphering the alterations in serum and liver proteome, biomarkers and patterns of biomarkers will be found that should be helpful in improving early detection, diagnosis and treatment monitoring of HCC. In the last few years, HCC has been extensively investigated using different proteomic approaches on HCC cell lines

    The prognosis of patients with hepatocellular carcinoma (HCC)accompanied by portal vein tumor thrombus (PVTT) is generally poor if left untreated: a median survival time of 2.7-4.0 mo has been reported. Furthermore, while transcatheter arterial chemoembolization (TACE) has been shown to be safe in selected patients, the median survival time with this treatment is still only 3.8-9.5 mo. Systemic single-agent chemotherapy for HCC with PVTT has failed to improve the prognosis, and the response rates have been less than 20%. While regional chemotherapy with low-dose cisplatin and 5-fluorouracil or interferon and 5-fluorouracil via hepatic arterial infusion has increased the response rate, the median survival time has not exceeded 12 (range 4.5-11.8) mo.Combined treatment consisting of radiation for PVTT and TACE for liver tumor has achieved a high response rate, but the median survival rates have still been only 3.8-10.7 mo. With hepatic resection as monotherapy,the 5-year survival rate and median survival time were reportedly 4%-28.5% and 6-14 mo. The most promising results were reported for combined treatments consisting of hepatectomy and TACE, chemotherapy, or internal radiation. The reported 5-year survival rates and median survival times were 42% and 31 mo for TACE followed by hepatectomy; 36.3% and 22.1 mo for hepatectomy followed by hepatic arterial infusion chemotherapy; and 56% for chemotherapy or internal radiation followed by hepatectomy.

    International Nuclear Information System (INIS)

    Full text: Biliary papillomatosis, is a rare, benign tumour characterised by extensive mucosal involvement of the bile duct with carcinoma in 30% of cases. Treatment has been largely limited to surgical resection and is often accompanied by tumour recurrence. Photodynamic therapy (PDT) was used to treat a 64 year old man with mucous-secreting papillomatosis of the common bile hepatic duct which presented with obstructive jaundice and recurrent cholangitis. The successful use of PDT in treating a case of cholangiocarcinoma and the treatment of similar colonic villous tumours encourage the use of PDT in this patient. Porfimer Sodium (Photofrin), 2 mg/kg was given intravenously 64 hours prior to light exposure. A Spectra Physics argon-ion pumped dye laser was used to provide 50 mW of 630 nm wavelength light at a 3 cm long diffusing tip attached to a 3 m optical fibre. A power density of approximately 15 mW.cm-2 was provided at the tissue surface under illumination at a radial distance of approximately 1.8 mm from the diffusing tip. The dose was designed to give a necrosis depth of 3 mm. A transparent 3.6 mm outer diameter catheter was placed in the duct using fluoroscopy and the fibre and diffusing tip then manoeuvred into position. The transparent catheter was left in place during the treatment and forced a minimum inner diameter on the duct of 3.6 mm and also helped to centre the diffuser within the duct. Repeat endoscopy, 48 hours after treatment revealed little duct mucous; necrosed tissue was removed with a balloon catheter with significant increase in size of the duct lumen. Since then, the patient's bilirubin has remained normal. Repeat endoscopic cholangiography one month later has shown no diminution in the diameter of the bile duct. The use of Photodynamic Therapy in the biliary tree using endoscopic retrograde placement of light source is feasible and the results in this patient encourage a trial of its use in operable bile duct carcinoma

    One hundred and four patients with histologic proven carcinoma of the endometrium were referred to our department for treatment. The median age was 65.5 years and the median follow-up was 38 months. Ninety-five was pos-menopaused, 7 peri and 2 were pre-menopaused. Sixteen patients were staged (pos-surgery) IA, 5 GI, 8 G2 and 3 G3. Thirty and four stage IB, 10 G1, 18 G2 and 1 G3. Twenty-five were stage IC, 9 G1, 9 G2 and 7 G3. Six were stage IIA, 2 GI, 3 G2 and 1 G3. Eight were stages IIB, 1 G1,3 G2 and 4 G3. Nine were stage IIA, 2 GI, 5 G2, 2 G3. Three were stage IIIB, 2 GI and 1 G2. One was stage III C G3, and two were IVA G3. Depending of the extension of the disease, patients underwent total hysterectomy and bilateral salpino-ooforectomy, or total hysterectomy and bilateral salpino-ooforectomy plus omentectomy or Werthein-Megs technique. All the patients IA and IB have no evidence of disease (NED). Twenty-four patients IC are NED and one presented distant metastasis. From the IIB patients, 6 are NED, one shown progressive local disease (PLD) and one died from disease. From the patients IIIA, 7 are NED, one DM and one PLD. From the IIIB patients one is NED and TWO are PLD. From the IIIC patient is NED two months after treatment and the IVA patients are NED three and four month after treatment. Eight patients have shown mild complications of treatment. The results of survival and complications are similar to the therapeutic with low dose rate brachytherapy, with the advantage of an outpatient treatment, without the inconvenience of impatient regime.

  2. Abdominopelvic radiation therapy in the treatment of ovarian carcinoma

    International Nuclear Information System (INIS)

    From May 1981 through December 1990, 167 patients with ovarian carcinoma were treated with whole abdominal irradiation. All patients of the first group (n = 62) presented with no or minimal (< 2 cm) residual disease at the time of irradiation. They received whole abdominal irradiation after initial surgery. Residual disease was left after initial surgery for patients of the second group (n = 105). They underwent a cisplatin polychemotherapy regimen followed by second-look laparotomy and abdominopelvic irradiation. The irradiation was performed by a four orthogonal field's technique. Thirty grays were given with a 25 MV photon beam. Boosts were performed in 50 cases (mean dose of 15 Gy): 91% have completed irradiation at the prescribed dose level: 5% had severe intestinal toxicity requiring surgery. The median follow-up was 68 months. The 5-year actuarial survival rate was 50%, 67% group 1, 40% group 2. Five-year actuarial survival was 84% for T1, 61.5% for T2, 38% for T3. Five-year survival depended on tumor rest after initial surgery (residual disease 36.5%, no residual disease 70%). For patients in group 2, the size of residual disease at second-look laparotomy was a significant prognostic factor: five-year actuarial survival 76% with negative second-look, microscopic residual disease (positive cytology or random biopsies) 60% microscopic disease after cytoreductive surgery at second-look 22%, macroscopic residual disease (small nodules) 10%. These results indicate that abdominopelvic irradiation is valuable in the treatment of ovarian carcinoma when there is no macroscopic residual disease after initial surgery or second-look laparotomy. To assess the place of radiotherapy, randomized trials comparing whole abdominal irradiation with chemotherapy, watch policy for staged patients is warranted. 42 Refs

  3. Radiotherapy. The mainstay in the treatment of early glottic carcinoma

    International Nuclear Information System (INIS)

    Early squamous cell carcinoma of the glottis may be effectively treated with surgery or radiation therapy. Controversy exists as to whether radiation therapy effects survival at the expense of vocal function by ultimately requiring more total laryngectomies for salvage of local tumor recurrence. This study reviewed the medical records of 185 patients with T1 or T2, NO invasive squamous cell carcinoma of the glottis treated with primary radiation therapy between 1969 and 1984. All patients were followed up for a minimum of 5 years after completion of therapy. One hundred sixty-one patients met the criteria for local control analysis. Radiation therapy controlled disease in 93% (105 of 113) of patients with T1 lesions and 73% (38 of 48) of those with T2 tumors. Ultimate control of disease for T1 and T2 lesions, including surgical salvage, was 111 (98%) of 113 and 44 (92%) of 48 patients, respectively. The rate of successful surgical salvage was 75% (T1) and 70% (T2). The T2 lesions with impaired vocal cord mobility or anterior commissure disease were identified as being at increased risk for recurrence after primary radiation therapy. Overall voice preservation was 90%. Our data demonstrate that radiation therapy effects disease-free survival rates that are comparable to those produced by surgery, without sacrificing voice. Although a small percentage of patients with selected early glottic lesions may be more effectively treated with primary conservation surgery, these data do not support a change in philosophy concerning primary treatment of early glottic cancer with radiation therapy

  4. Shen's Experience in Application of the Drugs for Tonifying the Kidney to Reduce and Withdraw Adrenocortical Hormone

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    @@Adrenocortical hormone (ACH) has antiinflammatory and antiallergic actions, changes stress state and controls the attack of some severe and obstinate diseases. The treatment of chronic diseases with ACH often leads to its dependence; especially oral administration of ACH for a long time is liable to inhibit the function of hypothalamus-pituitary-adrenocortical-thymic axis (HPAT), and results in the hypo-reservation of adrenal cortex. Hence, sudden ACH withdrawal or decrease often causes the disease recurrence, even adrenocortical crisis. Academician Shen Ziyin has a wealth of clinical experience in both the withdrawal and reduction of ACH and the keeping of therapeutical effectiveness to form his unique remedy in the application of drugs. Shen's rich experience is described as follows.

    Bevacizumab is a humanized monoclonal antibody that inhibits vascular endothelial growth factor, and it has been found to increase both progression-free survival and overall survival when it is combined with chemotherapeutic agents in the first-line and subsequent treatment of metastatic colorectal carcinoma. The objective of this study was to show the efficacy of maintenance treatment with capecitabine plus bevacizumab in patients with metastatic colorectal cancer who responded to treatment with FOLFIRI plus bevacizumab. The study included patients with metastatic colorectal cancer who received FOLFIRI plus bevacizumab as a first-line treatment. Patients who had objective response with FOLFIRI plus bevacizumab treatment after an average period of 6 months received a maintenance treatment with capecitabine plus bevacizumab (capecitabine 2 x 1000 mg/m2, 1 - 14 days, every 21 days, bevacizumab 7.5 mg/m2, every 21 days) until disease progression or toxicity. The time to progression on bevacizumab treatment was evaluated. A total of 29 patients (15 male, 14 female) were included. The mean age was 62 years. The mean number of cycles for maintenance treatment with capecitabine plus bevacizumab was 12. The median PFS was 16 ± 3 months, and OS was 42 ± 11 months. PFS and OS were remarkably higher in patients with a complete or near complete response to induction treatment. Fourteen patients (48%) experienced hand-foot syndrome associated with capecitabine plus bevacizumab treatment, without any severe toxicity. Inselected patients with metastatic colorectal carcinoma who had a remarkable objective response to FOLFIRI plus bevacizumab treatment, a maintenance treatment with capecitabine plus bevacizumab following FOLFIRI plus bevacizumab until disease progression may be a suitable, effective and tolerable regimen, which requires further studies.

    Full Text Available Pituitary carcinoma is a rare malignancy and is difficult to manage. Pituitary carcinomas commonly produce either PRL or ACTH, but some do not produce pituitary hormones. The alkylating reagent temozolomide (TMZ was recently shown to be effective as a treatment for pituitary carcinoma. Most of the published reports of TMZ use in pituitary carcinoma cases were against hormone-producing carcinomas. Only a few patients with a nonfunctioning pituitary carcinoma treated with TMZ have been reported. Here we describe our treatment of a patient with nonfunctioning pituitary carcinoma and a background of multiple endocrine neoplasia type 1. The pituitary carcinoma was accompanied by meningeal dissemination with cerebral and L1 spinal bone metastasis. The patient received continuous dosing of TMZ along with external radiation, followed by standard dosing of TMZ. There was an apparent antitumor response seen in MRI. MGMT, an enzyme antagonized by TMZ, was negative in the tumor. The therapeutic efficacy of TMZ and dosing schedules of TMZ in pituitary carcinoma are discussed.

    Full Text Available Temsirolimus is a novel inhibitor of mammalian target of rapamycin (mTOR, which is a central regulator of the response of tumour cells to growth and survival signals. When heavily pretreated patients with advanced solid tumours received intravenous (IV temsirolimus over a broad dose range, antitumour activity was observed in various tumour types, including advanced renal cell carcinoma (RCC. A study of singleagent temsirolimus in patients with cytokine-refractory metastatic RCC subsequently demonstrated antitumour activity and encouraging progression- free survival and overall survival. Temsirolimus was generally well tolerated over the 3 dose levels tested (25 mg, 75 mg or 250 mg weekly as a 30-minute IV infusion. The most frequent grade 3 or 4 treatment-related adverse events reported (n=110 were hyperglycemia (17%, hypophosphatemia (13%, anemia (9%, and hypertriglyceridemia (6%. Results from a randomized phase III study that enrolled previously untreated patients with advanced RCC and poor-prognostic features have recently demonstrated a significant increase in overall survival (p=0.0089 for patients who received temsirolimus 25 mg IV, 30-minute infusion once weekly compared with those who received interferon-alpha up to 18 million units subcutaneously thrice weekly. On the basis of improved survival, temsirolimus can be considered a first-line treatment for patients with advanced RCC.

  9. How can laparoscopic management assist radiation treatment in cervix carcinoma?

    International Nuclear Information System (INIS)

    Purpose: To determine the role of laparoscopic lymphadenectomy (pelvis ± para-aortic nodes) and laparoscopic hysterectomy in cervical cancer compared to 'classic radical surgery' in patients undergoing surgery in comparison with modern imaging in patients treated with radiotherapy alone.Materials and methods: The limitations of modern imaging are presented as well as how complication rates can be increased when classic laparotomy is followed by radiation therapy.Laparoscopic procedures are described with particular emphasis on how to provide information on lymph node metastases with the risk of overlooking microscopic involvement. A number of clinical experiences are cited to illustrate this problem and show how treatment approaches can be adapted.Results: The role of laparoscopy is evaluated according to different clinical situations and treatment protocols emphasizing the possibilities offered by this method to the radiotherapist. Conclusion: When developing laparoscopic techniques for the management of cervical carcinoma, caution must be exercised to ensure that these techniques are not detrimental to the prognosis.

    2011-12-01

    Full Text Available Despite its place as the third leading cause of cancer deaths worldwide, there are currently no approved chemotherapeutic agents, devices or techniques to treat hepatocellular carcinoma. Importantly, there have been no phase III studies demonstrating survival benefit, nor any randomized studies of treatment except for transarterial chemoembolization and most recently sorafenib. The importance of well-designed clinical trials of agents to treat HCC has never been greater. However, general clinical study design issues, combined with HCC-specific issues pose significant challenges in structuring such studies. HCC-related challenges include the heterogeneity of this cancer and the fact that it is frequently accompanied by significant comorbidities at diagnosis, such as active hepatitis B or C virus replication, substantial past or on-going alcohol use, and cirrhosis, itself often a fatal disease. The recently published comparison of a newer treatment, nolatrexed to doxorubicin, and comments about this study’s initial HCC diagnostic criteria, staging system, comparator therapy and choice of endpoints have provided a platform to discuss the challenges unique to the design of HCC clinical trials. The difficulty in accurately framing study results obtained from the constantly changing HCC clinical landscape and approaches to meet these challenges will be reviewed.

  11. Comparison of Treatment Results Between Adult and Juvenile Nasopharyngeal Carcinoma

    International Nuclear Information System (INIS)

    Purpose: Nasopharyngeal carcinoma (NPC) has a bimodal age distribution. In contrast to the adult variant, little is known about the juvenile form. This study examined the treatment results between adult (aNPC) and juvenile NPC (jNPC) patients for future treatment considerations in jNPC. Methods and Materials: The jNPC population included 53 patients treated at two institutions between 1972 and 2004. The aNPC population included 84 patients treated at one institution. The patients had received a median dose of 66 Gy of external beam radiotherapy and 72% underwent chemotherapy. The mean follow-up for surviving patients was 12.6 years for jNPC and 6.6 years for aNPC. Results: The jNPC patients presented with more advance stages than did the aNPC patients (92% vs. 67% Stage III-IV, p = .006). However, jNPC patients had significantly better overall survival (OS) than did aNPC patients. The 5-year OS rate was 71% for jNPC and 58% for aNPC (p = .03). The jNPC group also demonstrated a trend for greater relapse-free survival than the aNPC group (5-year relapse-free survival rate, 69% vs. 49%; p = .056). The pattern of failure analysis revealed that the jNPC patients had greater locoregional control and freedom from metastasis but the differences were not statistically significant. Univariate analysis for OS revealed that age group, nodal classification, and chemotherapy use were significant prognostic factors. Age group remained significant for OS on multivariate analysis, after adjusting for N classification and treatment. Conclusion: Despite more advance stage at presentation, jNPC patients had better survival than did aNPC patients. Future treatment strategies should take into consideration the long-term complications in these young patients.

    Background Adrenocortical carcinoma (ACC) is associated with poor survival rates. The objective of the study was to analyze ACC gene expression profiling data for prognostic biomarkers and therapeutic targets. Methods 44 ACC and 4 normal adrenals were profiled on Affymetrix U133 Plus 2 expression microarrays. Pathway and transcriptional enrichment analysis was performed. Protein levels were determined by western blot. Drug efficacy was assessed against ACC cell lines. Previously published expression datasets were analyzed for validation. Results Pathway enrichment analysis identified marked dysregulation of cyclin-dependent kinases and mitosis. Over-expression of PTTG1, which encodes securin, a negative regulator of p53, was identified as a marker of poor survival. Median survival for patients with tumors expressing high PTTG1 levels (log2 ratio of PTTG1 to average beta-actin <-3.04 ) was 1.8 years compared to 9.0 years if tumors expressed lower levels of PTTG1 (P<0.0001). Analysis of a previously published data set confirmed the association of high PTTG1 expression with a poor prognosis. Treatment of two ACC cell lines with vorinostat decreased securin levels and inhibited cell growth (IC50s of 1.69 uM and 0.891 uM, for SW-13 and H295R, respectively). Conclusion Over-expression of PTTG1 is correlated with poor survival in ACC. PTTG1/securin is a prognostic biomarker and warrants investigation as a therapeutic target. PMID:24238056

    Full Text Available Mehmet Hepgur, Sarmad Sadeghi, Tanya B Dorff, David I Quinn Division of Medical Oncology, University of Southern California Norris Comprehensive Cancer Center, Keck School of Medicine, Los Angeles, CA, USA Abstract: Renal cell carcinoma (RCC is an aggressive malignancy compared to other urological malignancies and has been associated with poor responses to conventional cytotoxic chemotherapy. Interferon-a and interleukin-2 were previously utilized in a limited number of patients with good performance status due to toxicity and safety issues. Over the last decade, through advances in the understanding of the biology and pathology of RCC, the important role of vascular endothelial growth factor (VEGF in RCC has been identified. Data from randomized trials have led to the approval of first-generation tyrosine kinase inhibitors (TKIs sorafenib, sunitinib, and pazopanib; however, these agents inhibit a wide variety of kinase targets and are associated with a range of adverse effects. More recently, a new generation TKI, axitinib, has been approved by the US Food and Drug Administration. Tivozanib is a novel TKI, which is a potent inhibitor of VEGF-1, VEGF-2, VEGF-3, c-kit, and PDGR kinases, with a more restricted target spectrum. Phase II and III studies have demonstrated significant activity and a favorable safety profile as an initial targeted treatment for advanced RCC. This review examines the emerging data with tivozanib for the treatment of advanced RCC. Preclinical investigations as well as Phase I, II, and III data are examined; data on the comparative benefits of tivozanib are reviewed. Finally, we discuss the future potential of tivozanib in combination, biomarkers associated with tivozanib response, and acquisition of resistance and nonkidney cancer indications.

  1. Trends and practices in diagnosis and treatment of hepatocellular carcinoma

    International Nuclear Information System (INIS)

    Hepatocellular carcinoma (HCC), or primary liver cancer, is one of the most common causes of cancer and cancer death globally, and has an increasing incidence. It is currently the fifth most common cancer among men and eighth among women. In some Asian and African countries, its incidence is similar to that of lung cancer. It carries a very poor prognosis; the majority of patients die within a year, making it the third most common cause of cancer death. Currently, the main treatments offering the chance of cure are surgical resection and liver transplantation. However, owing to late presentation and underlying liver cirrhosis, these are suitable only for a small minority of patients. Therefore, new investigative protocols in radiotherapy using the most advanced technologies have been developed with some promise of cure and effective palliation. However, no uniform recommendations exist and the use of radiotherapy is limited by pre-existing liver disease. The IAEA has extensive projects in radiation oncology in low and middle income countries, including areas in Asia and Africa where HCC is a common problem. Since there has been a reported significant increase in the use of radiotherapy in HCC, an expert review was considered timely to assess the role of radiotherapy within the entire framework of HCC management. This publication developed from the need to address this issue. A meeting on the current knowledge of HCC epidemiology and management protocols was convened in October 2008. The given task was to define the current role of radiotherapy in the management of HCC. The greatest number of patients requiring optimal management protocols for HCC lives in Asia and sub-Saharan Africa, where in many countries access to radiotherapy and cancer care in general is limited and resources for research and access to the most advanced technologies are not available. This review is intended for use in training courses and as a source of information on treatment decisions. It

    Thyroglossal duct carcinoma, which is usually diagnosed postoperatively, is a rare malignant tumor arising in the thyroglossal duct cyst. The definitive diag-nosis can be made only after microscopic examination. We retrospectively reviewed three cases of thyroglossal duct carcinoma diagnosed in Peking University School and Hospital of Stomatology from January 1986 to August 2006. Clinical and pathological features were investigated and the optimal treatment protocol was proposed. The constituent ratio of thyroglossal duct car-cinoma among surgically excised thyroglossal duct lesions was 2.9%. The clinical presentation of thyroglos-sal duct carcinoma was very similar to that of its benign counterpart. Two cases were diagnosed as thyroglossal duct cyst prior to the operation, the remaining one as dermoid cyst. All three cases were diagnosed as papillary carcinoma of thyroid origin after microscopic examina-tion. Primary thyroglossal duct carcinoma should con-form to the following criteria: localization of the carcinoma to a clearly demonstrable thyroglossal duct cyst or tract; clinically or histologically confirmed absence of carcinoma of the thyroid gland. Papillary carcinoma is the most common histological type, which usually develops slowly with an excellent Prognosis. The histological characteristics including: formation of pap-illary structure; nuclear morphological variations such as ground glass nuclei, pseudoinclusions, intranuclear grooves and filaments; concentrically calcified struc-tures termed psammoma bodies which is regarded as a strong indication of papillary carcinoma; and positiv-ity in immunohistological staining for thyroglobin. Sistrunk procedure of excision is the choice for treat-ment. A close follow-up is needed. In the presence of thyroid gland masses or cervical lymphadenopathy, thyroidectomy or neck dissection should be recom-mended. The effect of thyroid suppression therapy and radioactive iodine therapy is not conclusive.

    Full Text Available The predictive factors of prognosis and treatment strategies for small-cell carcinoma (SCC of the urinary tract are controversial. This study was aimed to investigate the clinical experience and management of patients with SCC of the urinary tract. We collected data of patients who were diagnosed with genitourinary SCC (GSCC between 2002 and 2013 and were treated in the Fudan University Shanghai Cancer Center. A total of 18 patients were diagnosed with GSCC of which 10 originated from the prostate, seven from the bladder and one from the adrenal gland. The mean follow-up time was 15.5 months and progression-free survival (PFS was 9.3 months. Primary tumor resection was attempted in 13 of 18 patients (72.2% in whom radical surgery was performed in six of 14 (42.9% limited disease patients. Most of the patients (13, 72.2% received cisplatin-based chemotherapy. Patients who had normal lactic dehydrogenase (LDH levels showed a significantly higher median PFS and overall survival (OS compared with patients with high LDH levels (P = 0.030, P= 0.010. Patients with limited disease treated with a radical operation experienced a non-significant (P = 0.211 longer PFS compared with patients who were not treated, but this reached statistical significance after analyzing OS (P = 0.211, P= 0.039. Our patients showed a poor prognosis as reported previously. Serum LDH levels beyond the normal range indicate a poor prognosis. For GSCC patients who are diagnosed with limited disease, radical surgery is strongly recommended along with cisplatin-based chemotherapy.

  5. Natural history, treatment, and course of papillary thyroid carcinoma

    International Nuclear Information System (INIS)

    We have analyzed the course of papillary thyroid carcinoma in 269 patients managed at the University of Chicago, with an average follow-up period of 12 yr from the time of diagnosis. Patients were categorized by clinical class; I, with intrathyroidal disease; II, with cervical nodal metastases; III, with extrathyroidal invasion; and IV, with distant metastases. Half of the patients had a history of thyroid enlargement known, on the average, for over 3 yr. In 15% of patients given thyroid hormone, the mass decreased in size. The peak incidence of cancer was when subjects were between 20-40 yr of age. Tumors averaged 2.4 cm in size; 21.6% had tumor capsule invasion, and 46% of patients had multifocal tumors. Sixty-six percent of the patients had near-total or total thyroidectomy. The overall incidence of postoperative hypoparathyroidism was 8.4%, but the incidence was zero in 83 near-total or total thyroidectomies carried out by 1 surgeon. Twenty-five percent of the patients had continuing or recurrent disease, and 8.2% died from cancer. Deaths occurred largely in patients with class III or IV disease. Cervical lymph nodes were associated with increased recurrences, but not increased deaths. Extrathyroidal invasion carried an increased risk of 5.8-fold for death, and distant metastases increased this risk 47-fold. Age over 45 yr at diagnosis increased the risk of death 32-fold. Tumor size over 3 cm increased the risk of death 5.8-fold. Surgical treatment combining lobectomy plus at least contralateral subtotal thyroidectomy was associated, by Cox proportional hazard analysis, with decreased risk of death in patients with tumors larger than 1 cm and decreased risk of recurrence among all patients, including patients in classes I and II, compared to patients who underwent unilateral thyroid surgery or bilateral subtotal resections

  10. The application of molecular nuclear medicine in imaging diagnosis and targeted treatment of thyroid carcinoma

    International Nuclear Information System (INIS)

    Thyroid carcinoma is the most common malignancy of endocrine system. Different pathological classifications of thyroid carcinoma differ greatly in biological behavior and prognosis. As a newly-emerging subject, molecular nuclear medicine has made rapid advances in both diagnosis and treatment of thyroid carcinoma. With the application of new imaging agents and devices such as SPECT/CT and PET/CT, molecular nuclear imaging can demonstrate, both qualitatively and quantitatively, the alterations in specific molecules of thyroid cancer on cellular and molecular level. Meanwhile, it is capable of utilizing radiopharmaceuticals to target specifically to these molecules. Here we present a review on the latest progresses in this field. (authors)

  11. Intestinal damage and malabsorption after treatment for cervical carcinoma

    International Nuclear Information System (INIS)

    Sixty-two patients with cervical carcinoma were treated in 1966 to 1968. Thirty-two patients who were alive in 1982 were reevaluated concerning intestinal function. An initial low folate value associated with the disease did not correlate with prognosis. A late low folate value indicated malabsorption and not recurrence of the carcinoma. Malabsorption was found in 5/23 patients (22%) and 3 of these (13%) had vitamin B12 deficiency. Intestinal damage in tumour free patients occurred in 2/62 (3%) patients. It is suggested that late silent complications such as malabsorption should be looked for in the preventive care of these patients. (Auth.)

  12. Role of radiation therapy in the treatment of parotid carcinomas

    International Nuclear Information System (INIS)

    Radiation therapy appears to be useful in postoperative management of patients with parotid gland tumors. Because the local recurrence rate is excessive, postoperative irradiation should be routinely considered for high grade mucoepidermoid carcinomas, all squamous cell, adeno- and undifferentiated carcinomas of the parotid. Doses should be at least equivalent to 6500 rads in 6 weeks to 4 cm. depth (or measured tumor depth). The radiation fields should cover the base of skull and lower neck to prevent extension of the cancer. (U.S.)

  13. Hepatocellular carcinoma with obstructive jaundice:diagnosis,treatment and prognosis

    2003-01-01

    Obstructive jaundice as the main clinical feature is uncommon in patients with hepatocellular carcinoma (HCC). Only 1-12 %of HCC patients manifest obstructive jaundice as the initial complaint. Such cases are clinically classified as "icteric type hepatoma", or "cholestatic type of HCC". Identification of this group of patients is important, because surgical treatment may be beneficial. HCC may involve the biliary tract in several different ways: tumor thrombosis, hemobilia,tumor compression, and diffuse tumor infiltration. Bile duct thrombosis (BDT) is one of the main causes for obstructive jaundice, and the previously reported incidence is 1.2-9 %.BDT might be benign, malignant, or a combination of both.Benign thrombi could be blood clots, pus, or sludge.Malignant thrombi could be primary intrabiliary malignant tumors, HCC with invasion to bile ducts, or metastatic cancer with bile duct invasion. The common clinical features of this type of HCC include: high level of serum AFP; history of cholangitis with dilation of intrahepatic bile duct; aggravating jaundice and rapidly developing into liver dysfunction. It is usually difficult to make diagnosis before operation, because of the low incidence rate, ignorant of this disease, and the difficulty for the imaging diagnosis to find the BDT preoperatively. Despite recent remarkable improvements in the imaging tools for diagnosis of HCC, such cases are still incorrectly diagnosed as cholangiocarcinoma or choledocholithiases. Ultrasonography (US) and CT are helpful in showing hepatic tumors and dilated intrahepatic and/or extrahepatic ducts containing dense material corresponding to tumor debris. Direct cholangiography including percutaneous transhepatic cholangiography (PTC) and endoscopic retrograde cholangiopancreatography (ERCP)remains the standard procedure to delineate the presence and level of biliary obstruction. Magnetic resonance cholangiopancreatography (MRCP) is superior to ERCP in interpreting the cause and

    Laser treatment is considered to be effective in treating carcinoma in situ of the penis. We, however, report a case with carcinoma in situ of the penis which developed invasive carcinoma and inguinal lymphnode metastases only 6 months after the laser treatment. A 74-year-old man with pseudophimosis presented with redness of the glans penis. A physical examination revealed thick erythema, 12 millimeters in diameter, around the external urethral meatus. Histologically, biopsy revealed squamous cell carcinoma in situ. No metastasis was suspected by physical examination and imaging studies. Although the lesion appeared to slightly extend into the urethra, it was primarily treated with the CO2 laser. Six months after the treatment, however, local recurrence was confirmed by the touch smear cytology, resulting in the partial amputation of the penis. The histopathological examination revealed subepithelial and marked lymphatic invasion of the tumor and positive margin in the urethral stump (squamous cell carcinoma in situ). Further, since bilateral superficial inguinal lymphnode swelling appeared, total amputation of the penis with perineal urethrotomy and pelvic/inguinal lymphnode dissection was performed subsequently. The metastases to bilateral inguinal lymphnodes were confirmed histologically. The patient received adjuvant chemotherapy and has been alive and well without evidence of disease 40 months after the initial treatment. PMID:11968805

    Oral verrucous carcinoma (OVC) is a verrucous variant of oral squamous cell carcinoma (OSCC), which accounts for 2-12% of all oral carcinomas with a 5-year survival rate of only approximately 50%. Enormous effort has been dedicated to this cancer, and the past decades have witnessed significant advances in relevant diagnostic and therapeutic approaches. Currently, there exist three challenges from primary sub-fields of research and clinical practice of the cancer, namely multifactorial etiology, complex molecular mechanism, and deficient treatment. This study reviews the existing literature on the cancer, encompassing its etiology, clinical manifestations and pathology, molecular mechanism, diagnosis and differential diagnosis, and treatment. For improved treatment of OVC, multifactorial etiology analysis, incorporation of effective biomarkers for mechanism illustration, and integration of multidisciplinary modalities are expounded, in an attempt to resolve the challenges and to provide a useful guide for future research in the field.

    The usefulness of gallium-67 as a radiopharmaceutical for the detection of carcinoma of the thyroid gland is investigated. Gallium-67 does not accumulate in a benign goitre. In combination with iodide and pertechnetate scintigraphy of the thyroid, the application of gallium-67 is important for the detection of malignancy in large goitres. To increase the efficiency of iodine-131 therapy, a low-iodine diet and intensive diuresis during four days preceding administration of radioactive iodide is recommended

  3. Hypofractionated radiation therapy for the treatment of feline facial squamous cell carcinoma

    International Nuclear Information System (INIS)

    The efficacy of hypofractionated radiation protocol for feline facial squamous cell carcinoma was evaluated. Hypofractionated radiation therapy was applied to five cats showing single or multiple facial squamous cell carcinomas, in a total of ten histologically confirmed neoplastic lesions. Of the lesions, two were staged as T1, four as T2, two as T3, and two as T4. The animals were submitted to four radiation fractions from 7.6 to 10 grays each, with one week intervals. The equipment was a linear accelerator with electrons beam. The cats were evaluated weekly during the treatment and 30 and 60 days after the end of the radiation therapy. In this study, 40% of the lesions had complete remission, 40% partial remission, and 20% did not respond to the treatment. Response rates were lower as compared to other protocols previously used. However, hypofractionated radiation protocol was considered safe for feline facial squamous cell carcinoma. (author)

  5. Adjuvant treatment and outcomes of stage III endometrial carcinoma

    International Nuclear Information System (INIS)

    Surgery with staging using FIGO (1988) classification is accepted management for stage III endometrial carcinoma. The delivery of adjuvant therapy is controversial and tends to be individualised. Retrospective review of stage III endometrial carcinoma patients who underwent radical surgery at the Royal Adelaide and Queen Elizabeth Hospitals from 1984 to 2003 was carried out. Medical records were reviewed for details of patient characteristics, surgery, histopathology, adjuvant therapy and recurrence/survival. Sixty-six patients with a median age of 69 (37-97), had a median follow-up of 26 months (1-188 ). For all stage III patients, the actuarial 5-year disease-free and overall survivals were 50 and 43% respectively. Thirty-five patients received pelvic +/- paraaortic radiotherapy, 5 whole abdominal radiotherapy, 14 vaginal brachytherapy boost, 10 chemotherapy and 13 adjuvant hormones. Forty-six percent of patients recurred in a median time of 13 months (0-95). For these patients, the sites of first recurrence were pelvis in 27%, pelvis and abdomen in 23%, abdomen alone in 13%, distant alone in 27%, distant and abdominal in 7% and all three sites in 3%. On univariate analysis disease-free survival was impacted by; age, grade, parametrial involvement, number of extrauterine sites, lymphovascular invasion, adjuvant radiotherapy to the pelvis alone and postoperative macroscopic residual disease. Lymphovascular invasion, post-operative residual disease and adjuvant pelvic radiotherapy remained significant on multivariate analysis. These outcomes for stage III endometrial carcinoma are comparable to the current literature. Ongoing research is required to establish the most appropriate adjuvant therapy in these high risk patients

    Irreversible electroporation (IRE) is a new nonthermal ablation modality that can be used to treat primary and metastatic lesions in the liver. This article describes the way IRE works, reviews safety and efficacy data, and presents strategies and recommendations for its use in everyday practice. In a series of liver lesions of various histologies, initial success was 100%; local recurrence rates were greater in larger lesions. In another series of hepatocellular carcinoma only, there was a 79% complete response rate overall and 93% in lesions less than 3 cm. Safety is comparable with those of other ablation modalities. IRE has advantages over other ablation modalities with comparable success rates. PMID:26365542

  7. Preliminary results of chemoradiation as a primary treatment for vulvar carcinoma

    International Nuclear Information System (INIS)

    Purpose: To assess the role of chemoradiation as a primary treatment for vulvar carcinoma. Methods and Materials: Between December 1989 and August 1997, there were 14 patients with the diagnosis of squamous cell carcinoma of the vulva. Two patients were excluded from this study because of advanced stage at presentation. Key information about the remaining 12 patients was extracted from their charts. All patients had biopsy prior to treatment, and were treated with chemoradiation. Radiation was administered to the vulva only. Surgical biopsies from the vulva and inguinal nodal dissection were done 4-6 weeks after radiation treatment. All patients were followed for evaluation of response and clinical detection of recurrence. The period of follow-up ranged from 8 to 125 months. Mean follow-up period was 41 months. Results: All 12 patients showed complete response to the treatment. Only 1 patient (8.3%) developed local recurrence at 3 months posttreatment. Another patient (8.3%) developed nodal recurrence at 30 months posttreatment. Both patients were salvaged by surgical treatment and remained disease free. The actuarial 5-year disease-free survival was 43%. The actuarial 3-year disease-free survival was 84%. The majority of patients developed mild-to-moderate complications due to chemoradiation. These were well tolerated and responded to medical treatment. None of the patients developed late complications to chemoradiation treatment. Conclusions: Chemoradiation is an effective primary treatment for vulvar carcinoma as shown by these successfully managed cases

    To study the clinical biocharacteristics of primary esophageal small-cell carcinoma (PESC) and factors influencing prognosis and to find rational indications for combination therapy. Methods: To analyze the clinical materials of 47 patients who had undergone an operation with PESC and to compare it with those patients with esophageal squamous-cell carcinoma (ESCC) or primary esophageal adenocarcinoma (PEAC). Results: The overall resectability, morbidity and 30-day mortality rates of PESC were 93.6%, 17.0%and 2.1% respectively, similar to those of ESCC or PEAC. TNM staging and lymph node metastasis were the major determinants influencing long-term survival. Tumor length, depth of tumor invasion and type of operation had little influence on long-term prognosis. The 5-year survival rate of PESC was 7.5%, which was much lower than that of ESCC and PEAC (P<0.01). Among the 42 deceased patents, one died of anastomotic leakage and the others died of remote metastasis and recurrence. Adjuvant chemotherapy did not help improve the patients' long-term survival. Conclusions: Compared with ESCC and PEAC, PESC is the most malignant type with early lymphatic and hematogenous metastases and poor prognosis. Lymph node metastasis is the major factor influencing the prognosis. Patients in stage 0, I and II a of PESC are indicated for surgical resection, while those in stage II b, III or IV should be managed with non-surgical combined therapy.

    Objective: To compare the transcatheter hepatic arterial chemoembolization (TACE) combined percutaneous ethanol injection (PEI)in treating primary hepatic carcinoma and the simple TACE treatment. Methods: 64 primary hepatic carcinoma patients were divided into union treatment group (n=32) and TACE group(n=32), with TACE combined PEI treatment and simple TACE treatment, respectively. The tumor size, AFP change, one year, two years, three years survival time and median survival time were observed and recorded during the course of treatment. Results: The tumor shrinkage rates and the AFP transferring into negative rates of the union and simple TACE groups were 84.4%, 62.7% and 77.4%, 50% respectively after the treatment with significant difference between the two groups. The 1 years, 2 years, 3 years and median survival rates of the union and simple TACE groups were 96.9%, 71.9%, 37.5%, 34.5 mo and 81.3%, 31.3%, 12.5%, 19.5 mo, respectively, showing conspicuously significance of both groups. Conclusion: TACE combined PEI for primary hepatic carcinoma is a better treatment of choice. (authors)

  16. Assessment of survey radiography and comparison with x-ray computed tomography for detection of hyperfunctioning adrenocortical tumors in dogs

    International Nuclear Information System (INIS)

    Results of abdominal survey radiography and x-ray computed tomography (CT) were compared in 13 dogs with hyperadrenocorticism histologically attributed to adrenocortical tumors. X-ray computed tomography enabled accurate localization of the tumor in all 13 dogs. Apart from 2 poorly demarcated irregular-shaped and mineralized carcinomas, there were no differences between adenoma (n = 3) and carcinoma (n = 10) on CT images. In 1 dog, invasion of the caudal vena cava by the tumor was suggested on CT images and was confirmed during surgery. Suspicion of adhesions between tumors of the right adrenal gland and the caudal vena cava on the basis of CT images was confirmed during surgery in only 2 of 6 dogs. Survey radiography allowed accurate localization of the tumor in 7 dogs (4 on the right side and 3 on the left). In 6 of these dogs, the tumor was visible as a well-demarcated soft tissue mass and, in the other dog, as a poorly demarcated mineralized mass. The smallest tumor visualized on survey radiographs had a diameter of 20 mm on CT images. Six tumors with diameter less than or equal to 20 mm were not visualized on survey radiographs. In 1 of these dogs, a mineralized nodule was found in the left adrenal region, without evidence of a mass. In a considerable number of cases, survey radiography can provide presurgical localization of adrenocortical tumors in dogs with hyperadrenocorticism; CT is redundant in these instances. In the absence of positive radiographic findings, CT is valuable for localization of adrenocortical tumors

    2002-01-01

    Objective: Bronchoplastic and pulmonary arterioplastic procedures have become increasingly popular in recent years as an alternative to pneumonectomy, especially for the patients with compromised cardiopulmonary reserve. Our experience with the procedures was reviewed and the operative technique, indication for the procedures, and long-term results were analyzed. Methods: From January 1977 to December 1996, 65 bronchoplasties, 4 pulmonary arterioplasties, and 3 combinedbroncho-angioplasties were performed for bronchogenic carcinoma. Of the 72 patients, thirty-one had stage I disease, 29 stage II and 12 stage III. Results: Onepatient (1.4%) died of bilateral pneumonitis after operation. Atelectasis occurred in 2 patients (2.8%), empyema in one (1.4%) and bronchial fistula in one (1.4%). There were no bronchial stenoses after bronchoplastic procedures, and no vascular complications after angioplastic procedures. The one-years, 3-year and 5-year survival rates for the entire group were 86.0%, 47.0%, and 29.8%, respectively. The three-year survival rates for the patients with stage I, II and III disease were 69.4%, 32.3% and 25.0%, respectively. There was no 5-year survival forpatients with stage III disease, whereas for patients with stage I and II disease, the 5-year survival rates were 48.6% and 10.8%, respectively. The differencein survival was significant between stage I and II disease (P=0.0001) and between stage I and III disease (P<0.0001), but not between stage II and III (P=0.0779). Conclusion: Bronchoplastic, pulmonary arterioplastic and broncho-angioplastic procedures can be performed safely. Brochoplastic procedures offer patients with bronchogenic carcinoma a long-term result comparable to that for radical lung resections. Angioplastic and combined angio-bronchoplastic procedures should only be employed in the patients who can not tolerate a pneumonectomy due to poor carciopulmonary reserve.

    BACKGROUND: α-fetoprotein (AFP) is used as a marker for hepatocellular carcinoma (HCC), which is influenced by hepatitis. Protein-induced vitamin K absence or antagonist II (PIVKA-II) is a sensitive diagnostic marker. Changes in these markers after treatment may reflect curability and predict outcome. METHODS: We conducted an analysis of prognosis in 470 HCC patients who received curative treatments, and examined the relationship between changes in AFP and PIVKA-II levels after 1 month of tre...

  4. Multidisciplinaly total-cell-kill treatment of bronchogenic small cell anaplastic carcinoma

    International Nuclear Information System (INIS)

    Survival time of the patients with bronchogenic small cell anaplastic cancer was studied. Combined treatment with six-drug combination chemotherapy ''METVFC'' (mitomycin C + cyclophosphamide + toyomycin + vincristine + 5-FU + cytosine arabinoside) and radiotherapy (5,000 rads in total) was given to 14 cases of limited disease of small cell carcinoma. Median survival was 8 months, one year and two year survival rates were 47% and 27%, respectively. Combined treatment with METVFC and small dose radiotherapy of 100 or 200 rads irradiation 4 hours before chemotherapy, followed by remission consolidation of 3,000 -- 4,000 rads radiotherapy, thereafter second line chemotherapy of ''COAM'' (cyclophosphamide + vincristine + ACNU + methotrexate) was given to 4 cases of limited disease of small cell carcinoma. All cases survived more than 1.5 years and two of them have retained complete remission more than 1.5 years. There are 6 cases with small cell carcinoma survived more than 3 years out of total 128 cases. They are all those of limited disease. They received combined treatment of chemotherapy and radiotherapy simultaneously or alternatively, followed by remission maintenance chemotherapy. One case of them died from cancer. Two cases died from another disease without lung cancer. Three cases survived healthy more than 3 to 8 years. In the limited disease, small cell carcinoma of the lung might be curable if the complete remission could continue more than three years. (author)

    The purpose of this work was to preliminarily investigate the efficacy and safety of high-intensity focused ultrasound treatment of hepatocellular carcinoma and hypersplenism. Nine patients with hepatocellular carcinoma complicated by hypersplenism (5 male and 4 female; median age, 56 years; range, 51-66 years) were treated with ultrasound-guided high-intensity focused ultrasound. Complications were recorded. Laboratory examination and magnetic resonance imaging were used to evaluate the efficacy. After high-intensity focused ultrasound treatment, mean spleen ablation ± SD of 28.76% ± 6.1% was discovered; meanwhile, the white blood cell count, platelet count, and liver function of the patients were substantially improved during the follow-up period. In addition, symptoms such as epistaxis and gingival bleeding were ameliorated or even eliminated, and the quality of life was improved. Follow-up imaging showed a nonperfused volume in the spleen and an absence of a tumor blood supply at the treated lesions in the liver. For the first time to our knowledge, high-intensity focused ultrasound ablation was used to treat hepatocellular carcinoma complicated by hypersplenism. High-intensity focused ultrasound may be an effective and safe alternative for treatment of hepatocellular carcinoma complicated by hypersplenism, but further studies are necessary to clarify the mechanisms.

  6. Evaluation of multi-disciplinary treatment combined with intraarterial chemotherapy for carcinoma of the mesopharynx

    International Nuclear Information System (INIS)

    Forty-seven cases of carcinoma of the mesopharynx, treated from 1973 to 1981 at Gunma Cancer Center, were evaluated. The following results were obtained, 1) According to histopathologic diagnosis, 37 were well-differentiated squamous cell carcinoma and other cases were poorly differentiated squamous cell carcinoma. 2) Classification of the site of the disease showed the most frequent site was lateral wall type (31 cases, 65.9 per cent) followed by anterior wall (9 cases), superior wall (5 cases), and posterior wall types (2 cases). 3) According to TN classification, there were 1 case in T1, 14 cases in T2, 24 cases in T3, and 7 cases in T4, N distribution revealed 27 cases N0, 20 cases N1, N2 and N3. 4) The most common treatment was intraarterial chemotherapy using 5-FU combined with external irradiation (15 cases, 31.9 per cent), external irradiation alone (14 cases, 29.7 per cent), external irradiation with Radium (8 cases, 17.0 per cent), and combined with cryosurgery 5 cases, 10.6 per cent). The five-year cumulative survival rate was 35.3 per cent. The lesion of mesopharyngeal carcinoma takes verious forms, so the treatment policy cannot be a standard one. Thus multi-disciplinary treatment should be applied for this disease. (author)

    Radiation therapy (RT) has been used for many years in the treatment of squamous cell carcinoma of the penis, both for the primary tumour and for lymph node involvement in the groin. The main advantage of RT is preservation of the penis, which eliminates the psychological distress associated with amputation. Further, the proponents of RT claim that it is curative and allows surgical salvage without affecting the ultimate disease-free survival (DFS). Cancer of the penis is a common disease in southern India with a crude incidence of 1.9 per 100 000 men (population-based cancer registry, Cancer Institute, Madras). At the centre an average of 70 patients with penile carcinoma are treated every year. This study reports our experience with the use of RT for patients with penile carcinoma. (author).

    Full Text Available There have been major advances recently on the therapeutic approaches of hepatitis B virus (HBV-related hepatocellular carcinoma (HCC. Surgical treatments are the key curative treatments of HCC, whereas local ablative treatments may also achieve clinical remission in selected cases. Trans-arterial locoregional therapies are regarded as palliative but still lead to improved survival. There have been major breakthroughs in the systemic therapies for HCC. The first marketed targeted therapy, sorafenib, was shown to improve survival in patients with advanced HCC. Studies on other targeted therapies also showed promising results. Suppressing HBV with effective antiviral treatment would also benefit HCC patients by reducing recurrence and improving liver function.

  11. Treatment of nasopharyngeal carcinoma and carcinoma of the nasal cavity and paranasal sinuses

    International Nuclear Information System (INIS)

    This course will address the primary and adjuvant role of ionizing radiation in the management of nasopharyngeal, nasal cavity and paranasal sinus cancers. Nasopharynx: Primary irradiation of nasopharyngeal carcinoma is technically challenging because of its proximity to the base of skull and central nervous system. Careful planning and an in-depth understanding of skull-base anatomy, patterns of local-regional spread and radiation tolerance of brain, spinal cord, optic nerves and retina are required. The theoretical advantages of three-dimensional planning and delivery of dose with modulated-intensity x-ray beams and protons, though promising, remain unsubstantiated. What has been established is that non-keratinizing WHO 2 and 3 cancers of the nasopharynx are more radiocurable than keratinizing ones and that chemotherapy in addition to radiation, though toxic, improves disease-free survival. The limited role of surgery and retreatment by external beam and endocavity brachytherapy will be discussed. Nasal Cavity: Radiation alone is preferentially used for cancers within the vestibule of the external nose because of its cosmetic importance and the impossible task of reconstructing it after rhinectomy. Cancers of the nasal cavity often behave like paranasal sinus cancers and require resection with adjuvant pre- or postoperative irradiation. Techniques of interrstitial implantation and external irradiation of the nose will be described. Paranasal Sinus: Radiation is used before or after surgery for resectable cancers of the paranasal sinus or as a single modality for unresectable ones. Those which involve the maxillary suprastructure are irradiated with ethmoido-maxillary technique while those of the infrastructure, are irradiated with a classic wedge-pair technique. Dose escalation is limited by the tolerance of the retina, optic nerves and brain

    Full Text Available Abstract Background Renal cell carcinoma (RCC represents approximately 3% of all adult cancers and is more common in males. Systemic treatment for RCC has improved following the introduction of tyrosine kinase inhibitors, such as sunitinib. The molecular targets of sunitinib are receptor tyrosine kinases (RTKs. Moreover, sunitinib has an additional anti-angiogenic effect through its inhibition of the vascular endothelial growth factor receptor activation. Case presentation We present a case of intra-abdominal abscess formation mimicking disease progression, in a patient with metastatic renal cell carcinoma during sunitinib treatment. Conclusion In the advancing era of molecular therapy of solid tumours, sunitinib has demonstrated significant efficacy in the post-cytokine setting treatment of metastatic renal cancer. Concurrently, however, increasing evidence has emerged to indicate that this class of drugs exert profound immunomodulatory effects on T cells and play major roles in immune tumor surveillance.

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

    Background The purpose of the study was to evaluate the role of neoadjuvant chemotherapy and embolization via the anterior branches of the bilateral internal iliac arteries in treating patients with advanced ovarian epithelial carcinoma.Methods Forty-two patients with advanced ovarian epithelial carcinoma (study group) were treated via the anterior branches of the bilateral internal iliac arteries after cytoreductive surgery and 7 courses of adjuvant platinum-based combination chemotherapy. Primary cytoreductive surgery was performed in 43 patients with advanced ovarian epithelial carcinoma (control group), and then followed by 8 courses of adjuvant platinum-based combination chemotherapy. The rate of optimal cytoreductive surgery, survival rate, blood loss during operation and operative time were investigated in the two groups. Statistical significance was asessed using Student's t test, the Chi-squre test and the log-rank test. Results In the study group, the rate of optimum debulking after platinum-based chemotherapy and embolization via the anterior branches of the bilateral internal iliac arteries was 71.43%(30/42) (χ2=10.06, P0.05).Conclusions Neoadjuvant platinum-based combination chemotherapy and embolization via the anterior branches of the bilateral internal iliac arteries is an alternative treatment for patients with advanced ovarian epithelial carcinoma, in whom the chance of optimal cytoreductive surgery is low. The treatment can reduce blood loss, decrease operative time, and increase the rate of optimal cytoreductive surgery; but the median survival can't be improved significantly.

    Adrenocortical cancer (ACC) is an uncommon primary neoplasm of the adrenal cortex with dismal prognosis. It often presents with symptoms and signs of adrenal cortical hormone hypersecretion and abdominal mass effect or is incidentally detected as an adrenal mass on imaging performed for other indications. Endocrine evaluation, comprehensive staging, and meticulous resection are crucial to ensure the best possible outcome. Despite extensive initial surgical resection, local and distant metastases are not uncommon with disappointing 5-year survival, although progress is being made at high-volume centers. Accurate restaging of recurrent disease is important to guide further management. Mitotane, external beam radiation and chemotherapy, and newer anticancer systemic treatments are used as adjunctives for inoperable disease and distant metastases. Contrast-enhanced CT and MRI are first-line imaging modalities for evaluation of ACC to characterize adrenal masses and to determine tumor resectability. Emerging literature supports F-FDG PET/CT use to determine the malignant potential of adrenal masses. In patients with a diagnosis of ACC, FDG PET/CT is sensitive for detecting metastatic disease, and its tumor accumulation has been correlated to pathology, Weiss scores, and prognosis. Metomidate, labeled with C for PET or with I for SPECT/CT, allows characterization of an adrenal mass as being of adrenocortical origin with high specificity. Taking advantage of its adrenocortical avidity, metomidate has been labeled with I for radionuclide therapy in a subset of ACC. In this review, we describe how nuclear medicine imaging, and specifically PET, can assist surgical management of ACC. PMID:26825212

    Full Text Available Liver cancer is the fifth most common cancer in men, the seventh most common in women, and the third most common cause of death from cancer worldwide. Only 30-40% of liver cancer patients present early enough to undergo curative treatments such as surgery or liver transplantation. Local treatment with radiofrequency ablation or ethanol injection is often reserved for non-surgical candidates with early stages of disease. Transarterial embolization has become a widely accepted treatment for asymptomatic patients with unresectable lesions. This review discusses in details the three major forms of transarterial therapies: Bland embolization, chemoembolization, and radioembolization.

  19. Treatment of squamous cell carcinoma of the maxillary alveolus and hard palate

    International Nuclear Information System (INIS)

    We report the treatment and clinical results for squamous cell carcinoma of the maxillary alveolus and hard palate. Fifty-nine cases with squamous cell carcinoma of the maxillary alveolus and hard palate treated between April 2001 and March 2009 were reviewed. For the initial treatment, 3 patients received brachytherapy, 43 patients underwent surgical resection alone, and 13 patients underwent surgical resection combined with radiotherapy or chemoradiotherapy. Local failure developed in 11 patients (18.6%), of which 7 patients were salvaged with further surgery. Five-year cumulative survival rates were 89.1% for all patients, 93.9% for the surgery-alone group and 71.3% for the preoperative treatment group. Further study is necessary to decide the optimal strategy and indications for preoperative treatment. Cervical lymph node metastasis was histologically confirmed in 16 patients (27.1%). Contralateral cervical lymph node metastasis developed in 8 patients. Five-year cumulative survival rates were 94.0% for pN0, 83.3% for pN1 and pN2b, and 70.0% for pN2c patients. Metastasis to the contralateral cervical lymph node should be considered in patients with maxillary alveolus and hard palate carcinoma. (author)

    International Nuclear Information System (INIS)

    Objective: To evaluate the efficacy of interventional therapy for hepatocellular carcinoma complicated by Budd-Chiari syndrome. Methods: Clinical data and imaging studies of 17 patients with hepatocellular carcinoma complicated by Budd-Chiari syndrome were retrospectively analyzed. Budd-Chiari syndrome was diagnosed by color Doppler ultrasound and confirmed by cavography in 17 patients. Hepatocellular carcinoma was diagnosed by fine-needle aspiration cytology in 5 patients,and by color Doppler ultrasound, computed tomography and/or MRI, and elevated level of alpha-fetoprotein in 12 patients. Both percutaneous transluminal angioplasty for treatment of obstruction of the inferior vena cava and transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma were performed in all patients. During follow-up, the tumor size, liver function, serum alpha-fetoprotein level and the recanalized inferior vena cava were evaluated by liver ultrasound, CT and laboratory examination. t test was used to compare the pressure. Results: Thirty-nine interventional procedures were performed in 17 patients and all operations were successful without complications, Over the follow-up period of 2 to 90 months after percutaneous transluminal angioplasty in 17 patients, re-occlusion of inferior vena cava occurred in only one patient. Following TACE, all 17 patients survived at two months follow- up, 13 patients survived at 6 months follow-up, 10 patients survived at 1 year follow-up, 5 patients survived at 2 years follow-up. The pressure of vena cava was (20.5±2.1) cm H2O (1 cm H2O=0.098 kPa) before the interventional therapy, while it was (3.6±1.0) cm H2O after it (t=30.32, P<0.05). Conclusion: Interventional therapy can be effectively performed for treatment of hepatocellular carcinoma complicated by Budd-Chiari syndrome. (authors)

    Full Text Available Renal cell carcinoma (RCC is the most common renal tumor and accounts for 3% of all adult cancers. The treatment of metastatic renal cell carcinoma (mRCC has recently evolved from being a predominantly cytokine-based treatment to the use of targeted agents, which include Sorafenib, Sunitinib, Bevacizumab, Temsirolimus, Everolimus, Pazopanib, Axitinib, and most recently Tivozanib. Despite these advances mRCC remains a major health problem. Additional studies are needed to optimize the use of these agents in both advanced and early stage disease, either in combination or sequentially. In addition the development of biomarkers should be a priority in order to guide rational tailored development of emerging agents. This literature review was conducted using PubMed, Medline, and Cochrane databases for articles published until January 2013. Abstracts from relevant meeting of the American Society of Clinical Oncology and the European society of medical oncology were also included.

    Full Text Available A 58-year old man, affected by metastatic thyroid carcinoma, experienced a progressive bilateral visual impairment. Ophthalmic examination revealed the presence of a choroidal mass with an associated exudative retinal detachment in both eyes. Twelve years before, a diagnosis of metastatic thyroid carcinoma had been established and the patient had been subject to several therapeutic procedures. In May 2007, he received a radiotherapy treatment to the left eye with an episcleral plaque and bilateral bulbar injection of bevacizumab. The patient had a rapid and stable visual acuity recovery. Twenty months after treatment, the lesion treated with radiotherapy was still stable whereas the contra-lateral lesion had evolved and determined a vitreal hemorrhage.

  4. Radiotherapy for maxillary carcinoma with special emphasis on treatment modalities used during the past 25 years

    International Nuclear Information System (INIS)

    We analyzed 419 patients with maxillary squamous cell carcinoma treated by different radiotherapeutic modalities during a 25-year period. Although the cure rate was relatively high in patients subjected to intensive short-period irradiation (50 - 65 Gy/3 - 4 wk), there were severe complications. The prognosis of patients treated with usual fractionated radiotherapy (60 - 70 Gy/5 - 6 wk) was as poor as that of patients exposed to orthovoltage X-ray. Combined treatment consisting of radiation, intra-arterial infusion of 5-Fu and necrotomy was most successful; the 5-year survival rate was 40% (19/47). Based on our findings, we conclude that necrotomy or partial post-radiotherapy resection are most important in the successful treatment of maxillary carcinoma. (author)

    Cryptogenic organizing pneumonia (COP) is an inflammatory lung disease involving the distal bronchioles, respiratory bronchioles, bronchiolar ducts, and alveolae. The etiology is usually unknown; however, there are several known causes and associated systemic diseases. Corticosteroid therapy is the best treatment option and the prognosis of COP is good, with recovery in up to 80% of patients. We described a patient with in-operable hepatocellular carcinoma (HCC) undergoing chemoembolization w...

    Background: interstitial low-dose-rate (LDR) brachytherapy allows conservative treatment of T1-T2 penile carcinoma. High-dose-rate (HDR) is often considered to be dangerous for interstitial implants because of a higher risk of complications, but numerous reports suggest that results may be comparable to LDR. Nevertheless, there are no data in the literature available regarding HDR interstitial brachytherapy for carcinoma of the penis. Case report: a 64-year-old man with T1 NO MO epidermoid carcinoma of the glans is reported. Interstitial HDR brachytherapy was performed using the stainless hollow needle technique and a breast template for fixation and good geometry. The dose delivered was 18 x 3 Gy twice daily. Results: after 232 days from brachytherapy, the patient was without any evidence of the tumor, experienced no serious radiation-induced complications, and had a fully functional organ. Conclusion: HDR interstitial brachytherapy is feasible in selected case of penis carcinoma, when careful planning and small single fractions are used. (orig.)

    The versatility of the omentum has led to its use as a surgical adjunct in the total oncological management of primary and recurrent colorectal carcinoma. The omentum is used as a transposition pedicle flap, broadly based on the left gastroepiploic vascular supply. Following abdominoperineal resection or low anterior resection of the rectum, the small bowel is elevated out of the pelvis by the omental bulk. The pelvic defect is reperitonealized and the risk of pelvic small bowel adhesions is diminished. With the increasing use of postoperative radiation to the pelvis for rectal carcinoma, the tolerance to therapy may be improved and the incidence of radiation enteritis and enteropathy should be reduced. Surgical complications such as leakage from low anterior anastomoses and pelvic abscesses, which may delay or contraindicate necessary postoperative radiation, are dramatically decreased. Reconstruction of the perineum with omental flap provides adequate soft tissue bulk and contour when a radical resection has been performed. The omental flap has been used in 24 patients with colorectal carcinoma; one flap was lost as a result of distal omental infarction in a patient with recurrent rectal carcinoma and radionecrosis of the perineum. The safety and ease of this procedure has allowed increased surgical innovation, especcially in the prevention and treatment of radiation complications.

  16. Clinical evaluation of multimodal treatment for squamous cell carcinoma of the maxillary sinus

    International Nuclear Information System (INIS)

    Seventy-seven patients with squamous cell carcinoma of the maxillary sinus were treated with radiotherapy and surgery (with or without intra-arterial infusion chemotherapy) from 1969 to 1986 at Tokyo Women's Medical College. The treatment given to the subjects was broadly separated into three categories: Treatment I (1969-1974), Treatment II (1975-1977), and Treatment III (1978-1986). Treatment I consisted of surgery and radiotherapy; Treatment II consisted of multimodal treatment by surgery and radiotherapy with 5-FU intra-arterial infusion chemotherapy (IAIC) from the superficial temporal artery; Treatment III consisted of surgery and radiotherapy with Adriamycin IAIC replacing 5-FU IAIC. Radiotherapy involved a total dose of 60 Gy/6 weeks in Treatment I as the standard, 50 Gy/5 weeks with 5-FU (250 mgx20 times/4 weeks) in Treatment III. Surgery by antrotomy was performed before radiotherapy and IAIC, and Denker's operation was done after radiotherapy with IAIC. The influence of patients' age, sex, T stage and N stage were examined as prognostic factors and no statistically significant differences were seen among each treatment periods. The 2-year control rate was 29% in period I, 27% in period II, and 58% in period III. The 5-year cumulative survival rate was 13% for period I, 40% for period II, and 54% for period III; the incidence of side effects during radiotherapy did not appear to increase, and the severity was at a tolerable level considering the results. However, late complications were seen in 6 cases (cataract, 5; obstinate sinusitis, 1). Thus, the study indicates that multimodal treatment using Adriamycin IAIC can minimize face deformity and allows effective function-saving treatment for carcinoma of the maxillary sinus. (author)

  17. The possibilities of radioimmune and radiologic monitoring of the treatment of patients with rectal carcinoma

    International Nuclear Information System (INIS)

    Full text: The method of dynamic control (monitoring) of the treatment efficiency of the patients with rectal carcinoma was developed. Data of dynamic examination (every 10 days) of 174 patients with rectal carcinoma received a specific treatment at the clinic of NOSC of Uzbekistan (Tashkent) were presented. Complex examination of the patients included the data of conventional clinical, special and radionuclide methods (RIA CEA, AFP, IRI ACTH in serum, gamma scintigraphy of liver) was carried out. For a selection of 17 parameters the factor analysis was used. Diagnostic significance of every parameter was determined. CEA and AFP markers were included as indices of tumor activity, ACTH and IRI markers were used as characterization of an organism's response to therapy. In the results of the multifactor investigations the monitoring programs 'Diagnosis-1' and 'Diagnosis-2' were developed. These programs permit to evaluate the treatment efficiency and correct the treatment schemes the case of the absence of the effect. Programmes 'Diagnosis-1' and Diagnosis-2' have a high both the diagnostic (89.9 ± 0.9% and 87.1 ± 0.9 %) and the prognostic (85.2 ± 1.3 % and 83.2 ± 1.3 %) significance. It is concluded that use of radionuclide methods permit to provide an adequate treatment in every case of rectal carcinoma. We suggesting: Use the Diagnosis-1' for evaluation of efficiency of different methods of treatment (CEA-produced tumors of rectum). Use the 'Diagnosis-2' for evaluation of efficiency of treatment of the CEA un-produced tumors of rectum. For objective and quantitative evaluation of the cancer of rectum it is necessary to determine the CEA and AKTH level in blood serum

  18. Breast carcinoma conservative treatment. Stages I and II

    International Nuclear Information System (INIS)

    From 1981 to 1988, 265 patients with breast cancer stages I and II (UICC-1987), were evaluated after conservative treatment with quadrantectomy plus axillectomy, radiotherapy and chemotherapy. After surgical treatment, the patients were submitted to radiation therapy in the breast. One hundred and fifty six (58,8%) patients were submitted to adjuvant chemotherapy. The median clinical follow-up period was 42.8 months with a minimum of 24 and a maximum of 99 months. Six (2,3%) patients presented local recurrence and 48 (18,1%) presented distant metastasis. After five years the total survival rate was 89,7% and the disease free survival rate was 75% in the same period. The study did not show significant differences among the clinical stages classified after surgery and the use of adjuvant chemotherapy did not influence the results of the many stages.

  19. Indications of endoscopic and thoracoscopic treatments for superficial esophageal carcinoma

    International Nuclear Information System (INIS)

    Explained are the treatments in the title involving chemo-radiotherapy application. At present, the endoscopic mucosal resection (EMR) and esophagectomy/reconstruction surgery are the major treatments of the esophageal cancer and EMR results in complete cure in most cases with superficial lesion. Authors' step-up strategy is the EMR for superficial cancer even with suspicious submucosal lesion, followed by histological examination for subsequent therapy below. For cases out of EMR indication or with high metastatic risk revealed after EMR above, the surgery and subsequent chemo-radiotherapy are indicated but significance of the latter is not established despite its recent increasing application. Endoscopic submucosal dissection (ESD) has been recently approved in the health insurance and is to be widely applied in future. However, these endoscopic treatments of esophagus, differing from those of stomach and large intestine, already have a wide range of indication and result in a sufficiently good local control, and therefore will not greatly contribute to the further improvement of quality of life (QOL) and survival. Endoscopic options other than EMR and ESD are the disruption by radiofrequency, photo-dynamic therapy by laser or photo-sensitizer, argon plasma coagulation (APC), authors' APC-subepthelial ablation, pure alcohol injection, etc. Thoracoscopic esophagectomy is now under clinical trial for submucosal cancer.

    Thyroid carcinomas may originate in the thyroid cells (follicular and papillary carcinoma, so-called differentiated carcinomas, constituting roughly 80-90% of cases), and the calcitonin-producing parafollicular C cells (medullary carcinoma, roughly 10%). The suspected diagnosis is clarified with the aid of ultrasonography, scintigraphy and fine-needle aspiration cytology. Primarily, carcinomas of the thyroid are treated surgically; in the case of differentiated carcinomas, surgery is followd by radio-iodine treatment, and in the follow-up period I-131 scintigraphy is performed. During this period, physical examination, ultrasonography of the neck, monitoring of the tumor markers, and treatment with levothyroxine are applied (TSH-suppressive in cases of differentiated carcinoma). In the event of a recurrence showing rapid progression, when surgical and nuclear medical treatment modalities have been exhausted, chemotherapy can be given. (orig.)

    To assess the clinical value of treatment with 131I for brain metastases from differentiated thyroid cancer (DTC), we have observed 8 cases of brain metastases from DTC who received follow-up after 131I therapy (2male, 6 female, aged 12~65 years). The results of 131I therapy were evaluated with clinical presentation, imaging scan and survival analysis. The main results are as follows. (1) All cases had been survival for 2~35 years in follow-up. (2)A space-occupying lesion in right cerebellum was reduced after taking 20.65 GBq and disappeared after 23.61 GBq,demonstrated by computed tomography. (3) The sequences and doses of 131I therapy were clearly decreased for the cases with total thyroidectomy in comparison with those with semithyroidectomy (p<0.01). (4) The brain metastases with lung and/or bone metastasis from DTC were 75% (6/8) and it was difficult to cure these metastases at the same time. It is concluded that the postoperative treatment of 131I for brain metastases from DTC after undergoing thyroidectomy may improve clinical symptoms and life quality, reduce lesions, and prolong survival.

    Hepatocellular carcinoma(HCC) is the sixth-most common type of cancer worldwide. The only definitive treatment modalities capable of achieving a cure are hepatic resection and hepatic transplantation. However, most patients are not candidates for these therapies. Overall, treatment options are driven by the stage of HCC. Early-stage disease is treated with ablative therapies, with radiofrequency ablation the ablative therapy of choice. Microwave ablation and irreversible electroporation are the other upcoming alternatives. Intermediate-stage disease is managed with transarterial chemoembolization(TACE), while advanced-stage disease is managed by sorafenib, with TACE and radioembolization as other alternatives.

  6. Radiation therapy for the treatment of feline advanced cutaneous squamous cell carcinoma

    International Nuclear Information System (INIS)

    The efficacy of radiation therapy for feline advanced cutaneous squamous cell carcinoma was evaluated. A full course radiation therapy protocol was applied to six cats showing single or multiple facial squamous cell carcinomas, in a total of seven histologically confirmed neoplastic lesions. Of the lesions, one was staged as T1, and six as T4 according to WHO staging system of epidermal tumors. The animals were submitted to twelve radiation fractions of 4 Gy each, on a Monday-Wednesday-Friday schedule, and the equipment used was an orthovoltage unit. Energy used was 120 kV, 15 mA and 2 mm aluminum filter. The cats were evaluated during the treatment and 30 and 60 days after the end of the radiation therapy. In this study, 87% of the lesions had complete remission and 13% partial remission to the treatment. Side effects were considered mild according to Veterinary Radiation Therapy Oncology Group Toxicity criteria, and included erythema, epilation and rhinitis. Radiation Therapy was considered safe for feline cutaneous squamous cell carcinoma, leading to mild side effects and can represent a good therapeutic option. (author)

    A review of the literature suggested that prolonged treatment time may lessen the probability of cure for patients with advanced squamous cell carcinoma of the upper aerodigestive tract. To shorten treatment time, rapid sequence treatment (RST) was devised in which chemotherapy, surgery, and irradation were administered in a total treatment time of 8 weeks. Twelve patients were treated and followed 3 years or longer. Medical complications were minor. Osteonecrosis occurred in each of the first five patients and was the only major complication of the protocol. Surgical techniques were modified, and no additional patient developed osteonecrosis. No patient developed local or regional recurrence. Two patients developed distant metastases and three other patients developed second primaries. Absolute survival was 50%. Rapid sequence treatment is an aggressive and potentially hazardous protocol that yielded encouraging results in this pilot study.

    In carcinoma of the vulva radical vulvectomy and lymphadenectomy are the treatments of choice if general, condition of the patient size and site of tumor are apt for surgery. The alternative method in high risk patients is a combination of surgical and radiotherapeutic treatment like electrocoagulation, resection, and radiation of the lymph vessels or electroresection and local electron-radiation at the surgically exposed area as well as inguinal and iliacal telecobalt treatment of the lymphnodes sometimes combined with selective lymphadenectomy. Radiation therapy itself as primary treatment seems to be inferior to other methods. The interstitial radiation treatment is only indicated in recurrencies or small tumors which are located in regions which are difficult to reach by surgery. (orig.)

    Sacrococcygeal teratomas and their malignant counterparts (germ cell tumors) are the most common solid tumors in neonates. Prompt diagnosis is essential because the frequency of malignant transformation increases from 10-20 % in neonates to 67 % in patients over 2 months of age. Cross-sectional imaging has largely replaced surgical exploration for staging these tumors and assessing their response to chemotherapy. Radiologists must be familiar with changes in the imaging findings of these tumors during and after treatment so that they can advise clinicians regarding the efficacy of therapy and the presence or absence of recurrent disease. From our study, magnetic resonance imaging appears to be a better modality for assessing sacral invasion and metastases and distinguishing fibrotic masses from recurrent tumor. (orig.).

  12. Locoregional Treatment for Breast Carcinoma After Hodgkin's Lymphoma: The Breast Conservation Option

    International Nuclear Information System (INIS)

    Purpose: To report clinical and pathologic characteristics and outcome of breast cancer (BC) after irradiation for Hodgkin’s lymphoma (HL) in women treated at the Institut Curie, with a special focus on the breast-conserving option. Methods and Materials: Medical records of 72 women who developed either ductal carcinoma in situ or Stage I–III invasive carcinoma of the breast after HL between 1978 and 2009 were retrospectively reviewed. Results: Median age at HL diagnosis was 23 years (range, 14–53 years). Median total dose received by the mediastinum was 40 Gy, mostly by a mantle-field technique. Breast cancers occurred after a median interval of 21 years (range, 5–40 years). Ductal invasive carcinoma and ductal carcinoma in situ represented, respectively, 51 cases (71%) and 14 cases (19%). Invasive BCs consisted of 47 cT0–2 tumors (82%), 5 cN1–3 tumors (9%), and 20 Grade 3 tumors (35%). Locoregional treatment for BCs consisted of mastectomy with (3) or without (36) radiotherapy in 39 patients and lumpectomy with (30) or without (2) adjuvant radiotherapy in 32 patients. The isocentric lateral decubitus radiation technique was used in 17 patients after breast-conserving surgery (57%). With a median follow-up of 7 years, 5-year overall survival rate and locoregional control rate were, respectively, 74.5% (95% confidence interval [CI], 64–88%) and 82% (95% CI, 72–93%) for invasive carcinoma and 100% (95% CI, 100 –100%) and 92% (95% CI, 79–100%) for in situ carcinoma. In patients with invasive tumors, the 5-year distant disease-free survival rate was 79% (95% CI, 69–91%), and 13 patients died of progressive BC. Contralateral BC was diagnosed in 10 patients (14%). Conclusions: Breast-conserving treatment can be an option for BCs that occur after HL, despite prior thoracic irradiation. It should consist of lumpectomy and adjuvant breast radiotherapy with use of adequate techniques, such as the lateral decubitus isocentric position, to protect the

Conclusions: Breast-conserving treatment can be an option for BCs that occur after HL, despite prior thoracic irradiation. It should consist of lumpectomy and adjuvant breast radiotherapy with use of adequate techniques, such as the lateral decubitus isocentric position, to protect the underlying heart

    Fifteen patients with advanced or recurrent squamous-cell carcinoma of the cervix, vulva, vagina, and urethra were treated with simultaneous combination chemotherapy (5-fluorouracil infusion and mitomycin C) and radiotherapy (3,000 rad for a period of three weeks). Three to four weeks after completion of radiotherapy, 13 of 15 patients achieved partial or complete tumor shrinkage. Nine of 15 patients are alive, eight of whom (at a median follow-up time of 24 months) have no evidence of disease. The longest survival time was 45 + months. There was minimal toxicity associated with this therapy. The results of this pilot study suggest that the simultaneous administration of radiation and chemotherapy is an effective method of treatment of advanced female genital tract carcinoma.

    The purpose of this study was to assess the anatomic and functional outcomes and compare the voice quality in patients affected by T1a glottic carcinoma treated with curative intent with radiotherapy or laser cordectomy. Fifty-seven cases were analysed: 27 after curative radiotherapy and 30 after laser cordectomy. All patients were studied with videolaryngostroboscopy, voice analysis by narrow spectrogram, and vocal parameters (Jitter, Shimmer, noise/harmonic ratio, and diplophonia). Videolaryngostroboscopy showed severe glottic inadequacy in 25% of cases treated with radiation and insufficient compensation 'ventricular band' or 'with arytenoid hyperadduction' in 65% of cases after surgery. Severe dysphonia on the electro-acoustic analysis of voice was observed in 25% of cases after radiation and 70% after laser (p radiotherapy compared with laser cordectomy. Voice outcome should be carefully considered in the treatment decision for T1 glottic carcinoma. PMID:15244253

    The results and experience gained with soft-radiation therapy of eyelid basal-cell carcinomas at the Dermatological University Clinic of Munich are presented in this thesis which supplies statistical data specific of patients and basilomas, discusses the irradiation technique used and compares it with those applied in other medical centres. Next it submits the curative results of eyelid basiloma irradiation comparing these with those obtained in other clinics. A separate chapter is dedicated to relapses showing i.a. possible recidivation causes followed by a presentation of each relapse case. The thesis concludes with a comparison of X-ray therapy and its results in the treatment of eyelid basal-cell carcinomas with other therapeutical methods and their results. (orig./MG)

  18. Treatment of clinically negative neck of squamous cell carcinoma in floor of mouth

    International Nuclear Information System (INIS)

    To determine how surgical treatment of the neck for N0 cases of squamous cell carcinoma in the floor of the mouth should be done, the pattern of occult cervical lymph node metastases was evaluated. The number of N0 cases without local failure from 1970 to 1999 was 53 (48 males and 5 females, average age 60.3 years old). T classification was as follows: T1: 14 patients, T2: 35 patients, T3: 4 patients. Initial treatment consisted of surgery only (29 patients), radiation therapy only (7 patients), surgery and radiation therapy (14 patients), surgery and chemotherapy (3 patients). Elective neck dissection (ENT) was performed in 16 patients. Histological cervical lymph node metastasis was detected in 18.9%, 2 of 16 patients who underwent ENT and 8 of 37 patients who underwent therapeutic neck dissection (TND). Frequency of secondary cervical lymph node metastasis by initial treatment and T classification distinction was not different. The sites of metastasis were level III except one case. The 5-year survival rate was 73.1% in the ENT group and 66.9% in the TND group. The results suggest that surgical treatment of the neck is not necessary for initial treatment for N0 cases of squamous cell carcinoma in the floor of the mouth. (author)

    Thyroid carcinoma is the most common malignancy of the endocrine system and it accounts approximately 1%-3% of all human cancers. Among the three subtypes of thyroid cancers, medullary thyroid carcinoma (MTC) is the most common cause of death in patients with multiple endocrine neoplasia (MEN) type 2A (MEN2A), MEN type 2B (MEN2B) and familial medullary thyroid carcinoma (FMTC). Generally, MTC accounts for up to 10% of all types of thyroid cancers. It is one of the aggressive forms of thyroid carcinoma which is manifested in childhood ages more than adults, and it comprises about 17% of all pediatric thyroid cancer. Like the other cancers, prevention of MTC is easier than its cure. In the recent decades (from 1993) the diagnosis of asymptomatic child carrying RET mutations in the affected families by MTC, has been provided by genetic screening, and prophylactic thyroidectomy is an efficacy therapeutic procedure. On the one hand, according to near the complete penetrance of the disease and its onset in the early years of life, it is required to accelerate the protection of at-risk children with relative affected by MTC and on the other hand, there are several obstructions to MTC treatment including: 1) the proband's refusal to disclose the RET mutation genetic testing results, 2) children's vulnerability because of their inability to participate in the informed consent, and 3) the existence of conflict between physicians and children's guardian. In this review article, the recommendations and ethical issues of MTC treatment in asymptomatic and at-risk children have been summarized. PMID:26974132

  2. Rearrangements at the 11p15 locus and overexpression of insulin-like growth factor-II gene in sporadic adrenocortical tumors

    Little is known about the pathophysiology of sporadic adrenocortical tumors in adults. Because loss of heterozygosity at the 11p15 locus has been described in childhood tumors, particularly in adrenocortical tumors associated with the Beckwith-Wiedemann syndrome, and because insulin-like growth factor-II (IGF-II) is a crucial regulator of fetal adrenal growth, the authors looked for structural analysis at the 11p15 locus and IGF-II gene expression in 23 sporadic adrenocortical adult tumors: 6 carcinomas (5 with Cushing`s syndrome and 1 nonsecreting) and 17 benign adenomas (13 with Cushing`s syndrome, 1 pure androgen secreting, and 3 nonsecreting). Twenty-one patients were informative at the 11p15 locus, and six (four carcinomas and two adenomas) of them (28.5%) exhibited 11p15 structural abnormalities in tumor DNA (five, a uniparental disomy and one, a mosaicism). In a single case that could be further studied, a paternal isodisomy was observed. Very high IGF-II mRNA contents were detected in seven tumors (30%; 5 of the 6 carcinomas and 2 of the 17 adenomas). They were particularly found in tumors with uniparental disomy at the 11p15 locus. Overall, a strong correlation existed between IGF-II mRNA contents and DNA demethylation at the IGF-II locus. These data show that genetic alterations involving the 11p15 locus were highly frequent in malignant tumors, but found only in rare adenomas. These results in combination with evidence for overexpression of IGF-II from the 11p15.5 locus suggest that abnormalities in structure and/or expression of the IGF-II gene play a role as a late event of a multistep process of tumorigenesis. 58 refs., 6 figs., 4 tabs.

  3. Interdependence of Gemcitabine Treatment, Transporter Expression, and Resistance in Human Pancreatic Carcinoma Cells

    Full Text Available Gemcitabine is widely used as first-line chemotherapeutic drug in the treatment of pancreatic cancer. Our previous experimental chemotherapy studies have shown that treatment of human pancreatic carcinoma cells with 5-fluorouracil (5-FU alters the cellular transporter expression profile and that modulation of the expression of multidrug resistance protein 5 (MRP5; ABCC5 influences the chemoresistance of these tumor cells. Here, we studied the influence of acute and chronic gemcitabine treatment on the expression of relevant uptake and export transporters in pancreatic carcinoma cells by reverse transcription-polymerase chain reaction (RT-PCR, quantitative RT-PCR, and immunoblot analyses. The specific role of MRP5 in cellular gemcitabine sensitivity was studied by cytotoxicity assays using MRP5-overexpressing and MRP5-silenced cells. Exposure to gemcitabine (12 nM for 3 days did not alter the messenger RNA (mRNA expression of MRP1, MRP3, MRP5, and equilibrative nucleoside transporter 1 (ENT1, whereas high dosages of the drug (20 µM for 1 hour elicited up-regulation of these transporters in most cell lines studied. In cells with acquired gemcitabine resistance (up to 160 nM gemcitabine, the mRNA or protein expression of the gemcitabine transporters MRP5 and ENT1 was upregulated in several cell lines. Combined treatment with 5-FU and gemcitabine caused a 5- to 40-fold increase in MRP5 and ENT1 expressions. Cytotoxicity assays using either MRP5-overexpressing (HEK and PANC-1 or MRP5-silenced (PANC1/shMRP5 cells indicated that MRP5 contributes to gemcitabine resistance. Thus, our novel data not only on drug-induced alterations of transporter expression relevant for gemcitabine uptake and export but also on the link between gemcitabine sensitivity and MRP5 expression may lead to improved strategies of future chemotherapy regimens using gemcitabine in pancreatic carcinoma patients.

  4. Squamous cell carcinoma of the anal canal: treatment by external beam irradiation

    International Nuclear Information System (INIS)

    External beam radiation therapy alone or in combination with curietherapy is the recommended treatment for anal canal carcinoma in some countries. In others, surgery is the sole accepted treatment. The results for 64 patients treated by external radiotherapy alone show excellent survival for stage T1T2 tumors but results are poor for large tumors (stage T4). Complications follow radiotherapy more frequently in those with stage T3 and T4 tumors. The analysis of local recurrences, complications and survival shows that radiation therapy may be sufficient treatment for stage T1 and T2 and for some stage T3 tumors. The importance of anal sphincter involvement and the poor quality of life for patients who are cured but develop complications, shows the need for combined treatment with surgery and perhaps with chemotherapy. For small tumors the results obtained by external radiotherapy alone are comparable with those obtained by external radiotherapy and curietherapy in terms of survival and complications. (Auth.)

  5. Investigation of acupuncture-point injection combined with intratumor injection of radionuclide phosphorus 32 in treatment of metastatic carcinoma

    International Nuclear Information System (INIS)

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

  6. Biological behavior and Treatment of Adenoid Cystic Carcinoma in the Head and Neck

    International Nuclear Information System (INIS)

    Biological Behavior and treatment results of 33 patients with Adenoid Cystic Carcinoma (ACC) in the Head and Neck at Yonsei Cancer Center for 10 years between 1971 and 1980 were retrospectively analyzed. Most common, primary site was minor salivary glands such as maxillary sinus, nasal cavity and base of tongue. The typical biological behavior of these tumors was very slowly in growth with long rime of duration (mean 19 months) from I month to 10 years and more frequent of nerve invasion but rare invasion of neck nodes. Local control and failure pattern in the results of treatment, 16 of 17 patients with irradiation alone were seen complete or partial response but 5 cases of loco regional recurrence, 2 cases of failure of neck node and 4 cases of distant metastasis as lung and brain. On the other hand, among 10 cases of surgery and postoperative irradiation, 2 cases of locoreginal failure and 3 cases of distant metastasis as lung and bone. 2 of 4 cases with surgery alone were recurred within primary site. Actuarial overall NED survival at 5 and 10 years were 52.6% and 42.8%, respectively. Survival rate of 10 patients with surgery and postoperative irradiation was more high than 17 patients of radiation alone. Therefore, we have known that surgery with postoperative adjunctive irradiation is most effective treatment modality of adenoid cystic carcinoma in the head and neck. Primary site, treatment modality and with or without nerve and bone invasion have influenced on prognosis

    Full Text Available G Anandappa, AE Hollingdale, TG EisenDepartment of Oncology, Cambridge University Hospitals NHS Foundation Trust, Cambridge, UKAbstract: With the increasing understanding of the biology of the disease and the development of targeted therapy, there has been a paradigm shift in the treatment of clear cell metastatic renal cell carcinoma (mRCC. Traditionally patients with metastatic RCC have been treated with immunotherapy which has limited efficacy. The multikinase inhibitors sunitinib, sorafenib and pazopanib, the VEGF antibody bevacizumab in combination with interferon and the mTOR inhibitor temsirolimus have all been shown to prolong progression-free survival in phase III studies. Here we review another mTOR inhibitor, everolimus (Afinitor®; Novartis, USA which was approved in March 2009 by the US FDA for treatment of targeted-therapy refractory metastatic renal cell cancer. The phase III study of everolimus (the RECORD study was terminated early after a significant difference in efficacy was noted in the treatment arm with everolimus (progression-free survival of 4.0 months in patients on the treatment arm vs 1.9 months in the placebo arm. The most common adverse events were stomatitis, pneumonitis, fatigue and infections. We review Phase I–III data with a particular emphasis on safety data and patient focused outcomes.Keywords: metastatic renal cell carcinoma, targeted therapy, mTOR, everolimus

  8. Prognostic factors in the treatment of locally advanced hepatocellular carcinoma with radiotherapy and arterial infusion

    International Nuclear Information System (INIS)

    Prognostic factors in the treatment of local advanced hepatocellular carcinoma with radiotherapy, transcatheter arterial embolization and arterial infusion. The treatment effects of radiotherapy and combination modality therapy for the local advanced hepatocellular carcinoma (HCC) were retrospectively reviewed. Three hundred and fifty-six patients of HCC (187 recurrent cases after surgical resection) were treated by: radiotherapy only ; bi-therapeutic method: hepatic artery ligation (HAL) and/or hepatic artery embolization (HAE) plus radiotherapy; and tri-therapeutic method (bi-therapeutic method plus hepatic artery infusion) from 1975 to 1996. Kaplan-Meier method has been used to evaluate the survival rates. There were no significant differences among these three treatment groups in the symptom relied rate, but the mean relief time period was much shorter in radiotherapy alone group (2.5 vs 44 months, P 0.05). There were evident differences in five-year survivals among these three treatment groups: 0 % for radiotherapy alone, 22.8 % for bi-therapeutic method and 38.8 % for tri-therapeutic method (P < 0.01). The prognosis was influenced by Okuda classification. Non-resectable local advanced HCC can be treated by the combination modality therapy, including radiotherapy, with a quite high cure rate. Radiotherapy alone can relief the symptoms. (authors)

The dogs received, twice in day, 0.5ml of corresponding solution into each external ear canal for 14 days. During the treatments were realized collections of data on 7th and 14th day and in post-treatment (seven days later the end of treatments. In these times were obtained blood samples by jugular venopunction, for serologic determination of level serum cortisol pre- and post-ACTH. The pre- and post-ACTH cortisol concentrations of fludrocortisone and betamethasone groups reduced significantly (P<0.05 compared with control, during the experiment. Betamethasone and fludrocortisone by otic administration produce considerable effects in the adrenocortical function.

    The pathogenetic mechanisms underlying the onset of adrenocortical tumors (ACTs) are still largely unknown. Recently, more attention has been paid to the role of insulin and insulin-like growth factor (IGF) system on general tumor development and progression. Increased levels of insulin, IGF-1 and IGF-2 are associated with tumor cell growth and increased risk of cancer promotion and progression in patients with type 2 diabetes. Insulin resistance and compensatory hyperinsulinemia may play a role in adrenal tumor growth through the activation of insulin and IGF-1 receptors. Interestingly, apparently non-functioning ACTs are often associated with a high prevalence of insulin resistance and metabolic syndrome. However, it is unclear if ACT develops from a primary insulin resistance and compensatory hyperinsulinemia or if insulin resistance is only secondary to the slight cortisol hypersecretion by ACT. The aim of this review is to summarize the current evidence regarding the relationship between hyperinsulinemia and adrenocortical tumors. PMID:26637955

    Forty-two patients with advanced squamous cell carcinoma of the vulva were treated with a combination regimen of bleomycin 180 mg and external irradiation 30-45 Gy. Twenty patients had primary lesions, and 22 patients had recurrent disease. Fifteen (75%) of the patients with primary disease showed objective response (five complete and ten partial response). Four underwent surgery. Of these, one is alive after 60 months with no evidence of disease. Two have died of unrelated causes without signs of recurrence. Seventeen relapsed and died of carcinoma of the vulva. Median survival for patients treated for primary disease was 8.0 months. Thirteen (59%) of 22 patients treated for recurrence showed objective response (two complete and eleven partial responses). None underwent surgery. All these patients died of carcinoma of the vulva. Median survival was 6.4 months. Toxicity was acceptable, and there were no treatment-related deaths. Even taking into account that our patients had very advanced disease, the results are disappointing. An increase of the radiation dose beyond the maximum of 45 Gy given, and more aggressive surgery, might have improved the results. (orig.).

    Osseous deposits secondary to advanced carcinoma of the prostate are a common feature of the disease. These deposits are most often seen in the lumbar spine and pelvis and cause severe and intractable pain, often requiring large quantities of strong analgesia for alleviation of pain. Relief of pain can be achieved by external irradiation of these deposits, but this relief may not be permanent and the disease may be so widespread that it is impracticable to treat all the deposits by irradiation. Deposits from carcinoma of the prostrate are usually multiple and all may cause pain at the same time. A method of delivering the radiation to all the deposits at the same time has been sought. Previous studies have shown that radioactive phosphorus (P32) can be used to obtain this localisation of radioactivity at sites of osseous activity. In this study 24 patients with bone metastases from carcinoma of the prostate were treated with radiophosphorus and methyl testosterone, or radiophosphorus with parathormone and calcium. An overall response rate of 58% shows this to be an effective palliative treatment. The results suggest there is a greater response when P32 is used in conjunction with parathormone and calcium, than with methyl testosterone. PMID:7307444

    Full Text Available An 18-year-old, male, castrated, captive-born leopard (Panthera pardus presented to Colorado State University’s Veterinary Teaching Hospital with a two-week history of regurgitation. Thoracic radiographs and ultrasound revealed a well-differentiated cranioventral mediastinal mass measuring 7.5 × 10 × 5.5 cm, impinging the esophagus. A sternotomy followed by mass excision was performed. The mass was diagnosed as an ectopic thyroid carcinoma. The leopard recovered from surgery with minimal complications and returned to near-normal activity levels for just under 6 months before rapidly declining. He had an acute onset of severe dyspnea and lethargy and was euthanized. On postmortem examination the tumor was found to involve the lung, liver, thyroid, parietal pleura, bronchial lymph nodes, and the internal intercostal muscles. This case report describes the history, diagnosis, surgical treatment, postoperative care, and recovery as well as the eventual decline, euthanasia, and necropsy of a leopard with thyroid carcinoma. When compared to thyroid carcinomas of domestic animals, the leopard’s disease process more closely resembles the disease process seen in domestic canines compared to domestic cats.

Currently available curative options, such as surgery and transplantation, are not available to patients with advanced stages of disease. Among the potential new treatments being investigated are microRNA (miRNA-based therapies. A number of preclinical studies have reported antitumor activities of miRNA mimics or anti-miRNA molecules. Optimal in vivo delivery of miRNA molecules is crucial to their action. To this end, significant progress has been made in the development of nanoparticles for in vivo delivery of miRNA molecules. Delivery of these molecules, alone or in combination with other drugs, promises to open new possibilities for therapeutic approaches to hepatocellular carcinoma.

    Parrots kept in zoos and private households often develop psychological and behavioural disorders. Despite knowing that such disorders have a multifactorial aetiology and that chronic stress is involved, little is known about their development mainly due to a poor understanding of the parrots’ physiology and the lack of validated methods to measure stress in these species. In birds, blood corticosterone concentrations provide information about adrenocortical activity. However, blood sampling techniques are difficult, highly invasive and inappropriate to investigate stressful situations and welfare conditions. Thus, a non-invasive method to measure steroid hormones is critically needed. Aiming to perform a physiological validation of a cortisone enzyme immunoassay (EIA) to measure glucocorticoid metabolites (GCM) in droppings of 24 Blue-fronted parrots (Amazona aestiva), two experiments were designed. During the experiments all droppings were collected at 3-h intervals. Initially, birds were sampled for 24 h (experiment 1) and one week later assigned to four different treatments (experiment 2): Control (undisturbed), Saline (0.2 mL of 0.9% NaCl IM), Dexamethasone (1 mg/kg IM) and Adrenocorticotropic hormone (ACTH; 25 IU IM). Treatments (always one week apart) were applied to all animals in a cross-over study design. A daily rhythm pattern in GCM excretion was detected but there were no sex differences (first experiment). Saline and dexamethasone treatments had no effect on GCM (not different from control concentrations). Following ACTH injection, GCM concentration increased about 13.1-fold (median) at the peak (after 3–9 h), and then dropped to pre-treatment concentrations. By a successful physiological validation, we demonstrated the suitability of the cortisone EIA to non-invasively monitor increased adrenocortical activity, and thus, stress in the Blue-fronted parrot. This method opens up new perspectives for investigating the connection between behavioural

    Adrenocortical oncocytic neoplasms (oncocytomas) are extremely rare; only approximately 159 cases have been described so far. The majority are nonfunctional and benign. We describe an unusual case of a functional oncocytoma secreting an excess of glucocorticoids (cortisol) and androgens (androstenedione and DHEAS), a pattern of plurihormonal cosecretion previously not reported in men, presenting with endocrine manifestations of Cushing's syndrome. The neoplasm was considered to be of uncertain malignant potential (borderline) according to the Lin-Weiss-Bisceglia criteria. PMID:27413559

    When incubated with [3H]cholesterol, a bovine adrenocortical mitochondrial pellet obtained by centrifugation at 12,000 x g yielded, as expected, only the C21O2 metabolites progesterone and pregnenolone. However, the steroidogenic potential of the 12,000 x g pellet fraction was augmented significantly by lyophilization. After lyophilization, the 12,000 x g pellet converted the sterol into C19 androgens and corticosteroids, in addition to C21O2 pregnane derivatives. Leaching the lyophilized mit...

    A 69-year-old man with a 100 pack-year history of smoking developed gross hematuria. His medical history included hypertension, a silent myocardial infarction, and a cerebrovascular accident complicated by seizures. Cystoscopy and biopsy showed a 4-cm mass at the right ureteral orifice positive for a high-grade papillary transitional cell carcinoma (TCC) with muscularis propria invasion (Fig 1). The computed tomography (CT)/positron emission tomography (PET) scan of the chest, abdomen, and pelvis showed hydronephrosis and hydroureter with marked cortical thinning and multiple bilateral PET-avid pulmonary nodules, with the largest in the left upper lung measuring 3.0 × 2.5 cm (Figs 2A, 3A), biopsy of which showed invasive high-grade urothelial carcinoma. The patient consented to join a clinical trial for metastatic TCC (USON [US Oncology Network study] 06040) involving treatment with gemcitabine, cisplatin, and sunitinib (GCS) 37.5 mg per day. Four days later, he experienced a 10-day hospitalization for acute pancreatitis and neutropenia. Sunitinib was discontinued, and he completed four additional cycles of GC. CT/PET showed that the right ureteral mass and all lung nodules had regressed or disappeared (Figs 2B, 3B). The largest remaining lung nodule at 1.4 cm showed no metabolic activity. He underwent a radical cystoprostatectomy and right nephroureterectomy, disclosing residual high-grade urothelial carcinoma infiltrating the full thickness of the ureteral wall. There was carcinoma in situ of the bladder, and 42 nodes were negative for cancer. The surgery was followed by a small, uncomplicated myocardial infarction. A scheduled left thoracotomy to remove the remaining nodule was cancelled. No additional chemotherapy was administered, and the patient remains free of recurrence 2 years from initiation of chemotherapy. The 1.4-cm nodule has calcified and remains stable and metabolically inactive. He has no sequelae of chemotherapy or surgery, with a creatinine

  5. Second malignancies following the treatment of differentiated thyroid carcinoma with radioiodine

    International Nuclear Information System (INIS)

    Full text: To see the incidence of second cancers in patients with well differentiated thyroid carcinoma after being treated with radioiodine. Medical records of 814 (417 males, 397 females) patients with differentiated thyroid cancer treated at Institute of Nuclear Medicine and Ultrasound, Dhaka were reviewed. The purpose was to investigate the incidence of second cancer in these patients after radioiodine therapy. The age range of the patient population treated with radioiodine was 9 to 69 years. Doses of radioiodine given were in the range of 30 to 100mCi for ablation and 150 to 250mCi for treatment of metastasis. The median follow-up period was 93.7± 15 months. Eleven (1.35 %) of the 814 patients developed a second malignancy. Two patients (0.25%) developed chronic myelogenous leukemia within a latency period of 5 years and after receiving a cumulative dose of 600- 670mCi. The over all incidence of second malignancy in the form of solid tumors was 1.10%. Of the nine patients with solid tumors, there were two patients with renal cell carcinoma, three patients with parotid gland tumor, one patient with pancreatic cancer, one with adenocarcinoma of the stomach, one with carcinoid tumor and one with small cell carcinoma of the lungs. The mean latency period for development of these tumors was 6.92 ± 3.934 years and the mean cumulative dose received by all these patients was 537.25±120.55 mCi. Follow-up of a fairly large cohort of patients treated with radioiodine showed a low incidence of second neoplasm. No relation was observed between the cumulative dose received and the development of a second malignancy. Thyroid carcinoma is a polygenic disease, which may be associated with other malignancies. Common environmental or genetic factors as well as long-term carcinogenic effects of radioiodine therapy should be considered. (author)

  6. Randomized study on late course accelerated hyperfractionation radiotherapy plus cisplatin in the treatment of esophageal carcinomas

    International Nuclear Information System (INIS)

    Objective: To investigate the therapeutic results of late course accelerated hyperfractionation (LCAH) radiotherapy plus cisplatin as a radiosensitizer in the treatment of esophageal carcinoma. Methods: One hundred and four patients with squamou s cell carcinoma of the esophagus were randomized into two groups: LCAH alone group (53 patients) and LCAH + cisplatin group (51 patients). The same irradiation technique was given for both groups with conventional fractionation (2 Gy daily, 5 times a week) in the first 3 weeks and late course accelerated hyperfractionation (1.5 Cry twice daily, a minimum interfraction interval of 6 hours, 5 days per week) in the last 2 weeks. The total dose was 60 Gy/5 wks. In LCAH + cisplatin group, cisplatin was given simultaneous with 20 mg once daily for 5 days in the 1st and 5th weeks. The acute and late side effects were evaluated during :and after the treatment. Results: The median survival time was 12.2 months and 17.0 months in the LCAH alone group and LCAH + cisplatin group. The 1- and 3-year survival rates in LCAH group were 52.8 % and 20.8%; while those of LCAH + cisplatin group were 58.0 % and 24.0% (P>0.05). The acute gastrointestinal toxicities and hematological toxicities were obvious in LCAH + cisplatin group, but no increased acute esophagitis or late complications was observed. Conclusions: Late course accelerated hyperfractionation radio-therapy used simultaneously with cisplatin tends to increase the overall survival rate compared with the late course accelerated hyperfractionation radiotherapy alone in the treatment of esophageal carcinoma.

    Cryptogenic organizing pneumonia (COP) is an inflammatory lung disease involving the distal bronchioles, respiratory bronchioles, bronchiolar ducts, and alveolae. The etiology is usually unknown; however, there are several known causes and associated systemic diseases. Corticosteroid therapy is the best treatment option and the prognosis of COP is good, with recovery in up to 80% of patients. We described a patient with in-operable hepatocellular carcinoma (HCC) undergoing chemoembolization with doxorubicin in a drug-eluting bead (DEB). COP developed in the patient after chemoembolization but resolved spontaneously in several months. PMID:26508948

    International Nuclear Information System (INIS)

    Objective: To discuss the technique, efficacy and clinical significance of cryoablation combined with transcatheter arterial chemoembolization(TACE) for the treatment of advanced hepatic carcinoma. Methods: One hundred and ninety-two patients, who accorded with the selected criterion, were divided into TACE group (n=100) and combination group (cryotherapy combined with TACE, n=92). Pre-and post-treatment AFP level, recurrence rate and life span between two groups were compared. Results: The complete necrosis rate of the tumor and the recurrence rate in TACE group were 29% and 42%, which were 88.04% and 24% in combination group, respectively. The serum AFP level was significantly decreased after treatment in both groups (P<0.05), and the reduction in AFP level was significantly greater in combination group than that in TACE group (P<0.05). During a follow-up of 30 months the survival rate at each evaluation period of combination group was higher than that of TACE group without exception. Conclusion: As an effective and safe technique, cryoablation combined with chemoembolization is far superior to simple TACE in treating advanced hepatic carcinoma. (authors)

    OBJECTIVE To evaluate the efficiency of surgery plus radiotherapy and chemotherapy versus radiotherapy plus chemotherapy in the treatment of older patients with stage I or II cervical carcinoma and to seek suitable treatment for such patients. METHODS The clinical data of 179 elderly women with stage la or lib cervical cancer were analyzed retrospectively. One hundred and thirty-four cases underwent radical hysterectomy followed by adjuvant radiotherapy and/or chemotherapy (Group 1). Forty-five cases underwent radiation therapy plus adjuvant chemotherapy (Group 2). RESULTS The 5-year survival rates in group 1 and group 2 were 78.3% and 49.1%(P=0.04), respectively. The incidence of complications in group1 was 47.0%. Three patients died of complications after radical hysterectomy. The incidence of complications in group 2 was 75.6%. CONCLUSION Elderly patients with stage I or II cervical carcinoma should receive an operation if possible. In addition they should receive adjuvant treatments according to their personal conditions, and be treated with appropriate adjuvant chemo-and/or radiotherapy.

  14. Treatment of carcinoma of the penis by iridium 192 wire implant

    International Nuclear Information System (INIS)

    Since 1971, a group of 22 adult patients with squamous cell carcinoma of the penis have been treated by iridium 192 wire implants. There were 6 T1 tumors, 14 T2 tumors and 2 T3; only one patient (T3) presented with local failure after implant. Local necrosis occurred in 2 patients without local tumoral recurrence, but was sufficient enough to warrant amputation. Thus 19/22 (86%) patients were locally cured with penile conservation. In these patients the most frequent posttherapeutic complication is chronic urethral stenosis (9/19 patients, 47%) requiring repeated instrumental dilations. Four patients presented with initial inguinal mestastatic nodes; only one was cured by radiosurgical treatment. Among patients without metastatic nodes at the time of diagnosis, none had delayed metastatic nodes. Three patients died of nodal evolution, 5 patients died of intercurrent disease without evidence of disease and 14 are now alive and NED. It appears that iridium 192 wire implant is the most effective conservative treatment of invasive squamous cell carcinoma of the penis; however, these results confirm that no particular treatment is required for inguinal nodal areas for patients who initially present with no disease

    Fibrolamellar hepatocellular carcinoma (FL-HCC) is a malignant liver tumor which is thought to be a variant of conventional hepatocellular carcinoma (HCC). It accounts for a small proportion of HCC cases and occurs in a distinctly different group of patients which are young and usually not in the setting of chronic liver disease. The diagnosis of FL-HCC requires the integration of clinical information, imaging studies, and histology. In terms of the treatment options, the only potentially curative treatment option for patients who have resectable disease is surgery either liver resection (LR) or liver transplantation (LT). When performed in a context of aggressive therapy, long-term outcomes after surgery, particularly liver resection for FL-HCC, were favorable. The clinical outcome of patients with unresectable disease is suboptimal with median survival of less than 12 months. The aim of this review is to update the available evidence on diagnosis, treatment options, outcome predictors, and recent developments of patients with this rare disease and to provide a summarized overview of the available literature.

  17. Squamous cell carcinoma of the oropharynx--an analysis of treatment results in 289 consecutive patients

    International Nuclear Information System (INIS)

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

    To evaluate the incidence and risk factors of post-treatment intracranial hemorrhage of brain metastases from hepatocellular carcinoma (HCC). Medical records of 81 patients who have been diagnosed of brain metastases from HCC and underwent surgery, radiosurgery and/or whole brain radiotherapy (WBRT) between January 2000 and December 2013 were retrospectively reviewed. Intracranial hemorrhage was present in 64 patients (79%) at the time of diagnosis. Median value of alpha-fetoprotein (AFP) level was 1,700 ng/mL. The Eastern Cooperative Oncology Group (ECOG) performance status for 20 patients was greater than 2. Fifty-seven patients underwent WBRT and the others were treated with surgery and/or radiosurgery without WBRT. During follow-up, 12 events of intracranial hemorrhage after treatment were identified. Three-month post-treatment hemorrhage rate was 16.1%. Multivariate analyses revealed that ECOG performance status, AFP, and WBRT were associated with post-treatment hemorrhage (p = 0.013, 0.013, and 0.003, respectively). Kaplan-Meier analysis showed that 3-month post-treatment hemorrhage rate of new lesion was higher in patients treated without WBRT, although statistical significance was not reached. (18.6% vs. 4.6%; p = 0.104). Ten of 12 patients with post-treatment hemorrhage died with neurologic cause. WBRT should be considered to prevent post-treatment hemorrhage in the treatment of brain metastases from HCC.

    2012-06-01

    Full Text Available PURPOSE: The objective of this study was to compare the estimated cost of clinical and surgical treatment for basl cell carcinoma of the eyelid. METHODS: This was a pilot study of 12 patients with basal cell carcinoma receiving treatment with 5% imiquimod cream at the ocular plastic surgery center, medical school University of São Paulo (HC-FMUSP, Brazil. The cost of clinical treatment was estimated based on the time of treatment and amount of medication consumed by patients in the home setting. The cost of surgical treatment was estimated by ophthalmologists with experience in reconstructive plastic surgery based on analysis of images of the same patients. Surgeons responded to a questionnaire with four questions about surgical technique, surgical materials required, estimated duration of surgery and type of anesthesia. RESULTS: Immunotherapy lasted from 8 to 12 weeks.All patients reported each coldstored sachet with 5% imiquimod cream lasted 3 days.According to the institution, a box with 12 sachets costs BRL 480.00. Patients required 1.58-3.11 boxes for complete treatment, corresponding to a total cost of BRL 758.401,492.80. Based on image analysis, surgeons evaluated surgery would require 1-3 hours. The estimated cost of surgery room and staff was BRL 263.00, to which the cost of supplies was added. Thus, the total cost of surgical treatment was BRL 272.61-864.82. On the average, immunotherapy was 57,64% more costly than surgical treatment. CONCLUSIONS: Malignant eyelid tumors are a common finding in clinical ophthalmology. Surgery is still the treatment of choice at our institution, but immunotherapy with 5% imiquimod cream may be indicated for patients with multiple lesions or high surgical risk and for patients declining surgery for reasons of fear or esthetic concerns.The ability to estimate costs related to the treatment of malignant eyelid tumors is an important aid in the financial planning of health care institutions.

    Full Text Available SUMMARY: Carcinomas of the lip and the commisure show a milder biological behavior as well as higher differentiation and better prognosis in comparison with these of the oral cavity. Therapeutic management, as for malignant tumors, includes radical resection together with functional and aesthetic rehabilitation. Aim of the paper is to present the multidisciplinary treatment of a case of a lip commissure carcinoma. Case presentation: Α 68 years old patient with a recurrent squamous carcinoma of the lower lip and the commissure was referred for treatment. The treatment plan included an extensive surgical excision of the lesion, suprahomohyoid neck dissection, reconstruction of the defect with local flaps, additional radiotherapy and dental rehabilitation with implants in a later stage. Seven years post- operation the patient is free of disease.The functional and aesthetic results are satisfying, considering the large soft tissue defect.

  3. Treatment Trends and Outcomes of Small-Cell Carcinoma of the Bladder

    International Nuclear Information System (INIS)

    Purpose: Treatment for small-cell carcinoma of the bladder is largely guided by case reports, retrospective reviews, and small prospective trials. This study aimed to study outcomes using a large population-based database. Methods: The Surveillance, Epidemiology, and End Results–Medicare database (1991–2005) was used to analyze how different treatment combinations of specific bladder surgeries, chemotherapy, and radiation affected patient outcomes. Trends in the use of these combinations over time were also analyzed. Results: A total of 533 patients were retrieved from the database. A bladder-sparing approach involving transurethral resection of the bladder tumor (TURBT) combined with chemotherapy and radiation yielded no significant difference in overall survival compared with patients undergoing at least a cystectomy (of whom over 90% received radical cystectomy) with chemotherapy (p > 0.05). The analysis of treatment trends indicated that these two general strategies for cure combined to account for fewer than 20% of patients. A majority of patients (54%) received TURBT as their only surgical treatment, and a subset analysis of these patients indicated that chemotherapy played a role in all stages of disease (p < 0.05) whereas radiation improved overall survival in regional-stage disease (p < 0.05). Conclusion: Relatively few patients with small-cell carcinoma of the bladder receive potentially curative therapies. Chemotherapy should be a major component of treatment. Cystectomy and bladder-sparing approaches represent two viable strategies and deserve further investigation to identify the patients who may benefit from organ preservation or not. In addition, the role of radiation in regional-stage disease should be investigated further, because it positively affects survival after TURBT.

    Full Text Available As a result of mammographic detection, ductal carcinoma in situ (DCIS is an increasing problem in breast clinics. Both histopathology and molecular profiling can identify subtypes likely to progress to invasive disease, but there is no subgroup with a zero likelihood of subsequent invasion. In patients with low/intermediate grade DCIS, if breast irradiation is not being carried out after free margins have been achieved the patient should be aware of the risks of withholding and the benefits and morbidity of adjuvant radiotherapy. Either tamoxifen or an aromatase inhibitor may be of value in those with low/intermediate ER+ve disease if radiotherapy is being withheld. For those patients with extensive or multicentric DCIS, mastectomy is the appropriate treatment. This is best combined with sentinel node biopsy and all such cases should be offered immediate reconstruction.----------------------------Cite this article as:Fentiman IS.

  6. Analysis of treatment and results in patients with advanced hypopharyngeal carcinomas

    International Nuclear Information System (INIS)

    Between 1991 and 1997, 42 patients with advanced stage III or IVA or IVB hypopharyngeal cancer received primary treatment at our clinic. Treatment and results in these cases were analyzed retrospectively. Thirty three patients with resectable hypopharyngeal carcinomas received 1-3 courses of neoadjuvant chemotherapy (NAC) involving a combination of cisplatin 60 mg/m2 and 5-fluorouracil 800 or 1,000 mg/m2 x 5 days, followed by total laryngopharyngectomy plus postoperative radiotherapy in 24 patients (group A) or followed by 70 Gy radiotherapy with radiation sensitizer in 9 patients because of self rejection of the operation (group B). Nine patients with unresectable hypopharyngeal carcinomas received neoadjuvant chemotherapy followed by radiotherapy or received radiotherapy only (group C). For the entire group, 5-year overall survival was 38% (group A 53%, group B 22%, group C 0%). The survival was statistically better (p<0.05) in group A than in group B. Better results were obtained for combined therapy including radical surgery in terms of overall survival. The response rate of NAC was 70%. In the patients who received operation, clinical and pathological CR rate was (8% in primary lesion, clinical CR rate was 5% and pathological CR rate was 23% in regional lymph nodes. Therefore sensitivity of the clinical CR evaluation was 50% in primary lesion and 20% in regional lymph nodes. Specificity of the clinical CR evaluation was 95% in primary lesion and 100% in regional lymph nodes. (author)

  7. Sensorineural Hearing Loss After Treatment of Nasopharyngeal Carcinoma: A Longitudinal Analysis

    International Nuclear Information System (INIS)

    Purpose: To analyze the effects of radiotherapy (RT) and chemotherapy in relation to sensorineural hearing loss (SNHL) after contemporary treatment of nasopharyngeal carcinoma. Methods and Materials: A total of 87 nasopharyngeal carcinoma patients were treated with RT or chemoradiotherapy using either three-dimensional conformal RT or intensity-modulated RT between 2004 and 2005. Tympanometry and pure-tone audiogram assessments were performed before treatment and then serially at 6-month intervals. The dose-volume data of the cochlea were analyzed. The effects of cisplatin administered in concurrent and nonconcurrent phases was explored. Results: Of the 170 eligible ears, RT (n = 30) and chemoradiotherapy (n = 140) resulted in 40% (n = 12) and 56.4% (n = 79) persistent SNHL (≥15 dB loss), respectively, after a median follow-up of 2 years. SNHL at a high frequency was more frequent statistically in the chemoradiotherapy group than in the RT-alone group (55% vs. 33.3%, p 2 increase (p < 0.01), respectively. Age, gender, and nonconcurrent cisplatin dose were not statistically significant factors. A mean radiation dose to the cochlea of <47 Gy would result in <15% of patients developing severe (≥30 dB) high-frequency SNHL. Conclusion: The results of our study have shown that high-frequency SNHL is significantly related to the mean cochlea dose and the concurrent cisplatin dose. A mean dose constraint of 47 Gy to the cochlea is recommended to minimize SNHL after chemoradiotherapy.

  9. Treatment Result in Advanced T3 and T4 Glottic Carcinoma; YUMC Experience

    International Nuclear Information System (INIS)

    Between January 1980 and September 1988, 68 patients with advanced T3 and T4 glottic carcinoma were treated with RT and surgery/RT in the Department of Radiation Oncology, Yonsei Cancer Center and ENT, Yonsei University College of Medicine. The mean age was 60 years old (range 33 to 79 year old). The 34 patients were treated with irradiation alone, and the remaining 34 patients with surgery and irradiation. Initial nodal presentation was 37% (25/68); 31% (11/34) in RT alone group and 41% (14/34) in combined treatment group. The minimum follow-up was 2 years. The local control rate after treatment was 47% in RT alone group and 65% in combined treatment group; 57% for node negative and 27% for node positive patients treated with RT alone; 65% for node negative and 64% for node positive patients treated with combined treatment. The treatment failure was observed in 30 patients; 14 patients for primary local failure, 6 patients for regional nodal failure, 6 patients for local and regional failure, 26 patients for primary failure and/or distant metastasis, and 2 patient for regional failure and/or distant metastasis. The overall 5-year survival rate was 57%; 37% in RT alone group and 76% in combined treatment group; 55% for node negative and 20% for node positive patients treated with RT alone; 73% for node negative and 77% for node positive patients treated with combined treatment. In conclusion, the combined treatment groups in the treatment of advanced T3 and T4 glottic cancer showed the better results in local control rates and 5-year actuarial survival rates than RT alone group. We suggest that total laryngectomy and postoperative RT in the most patients of advanced glottic cancer were performed. However, in cases of node negative patients, RT alone is prefer as a treatment modality over combined surgery and RT since the treatment results were comparable and furthermore functional preservation could be achieved

  10. Cushing's Syndrome caused by pigmented adrenocortical micro nodular dysplasia - A familial case

    International Nuclear Information System (INIS)

    Introduction: We present a Case of Cushing's syndrome (CS) in a 16 year old male adolescent. Adrenocortical micro nodular dysplasia is a rare cause of CS. It mostly develops in the first two decades of life. In pathogenesis a stimulatory effect of circulating Immunoglobulins on adrenal steroidogenesis has been postulated. Familial cases have been reported in relation to Carney's Syndrome. We report the clinical case at first diagnosis and preoperative follow up of 1 year prior to treatment. The leading symptoms were severe bilateral (fibrotic) gynaecomastia, weight gain and growth retardation, without hypertension,but osteoporosis, secondary hypogonadism and glucose intolerance. Laboratory findings and the results of functional tests were diagnostic for CS. In addition LDH (I-131 Isotopes), CK, Lipoproteins, GPT, Androstendion, Prolactin were elevated. MRI abdomen revealed a slight enlargement of the adrenals, and suspected a bilateral micro nodular dysplasia. Iodo-cholesterol-scan under dexamethason suppression showed a diffuse bilateral Iodo-cholesterol uptake confirming the autonomous production of cortisol bilateral in the adrenals.Whole body bone scan showed a diffuse reduced diphosphonate uptake in the skeleton and the growth plates. The bone mineral density was significantly reduced.Radiologically osteoporosis was overt. The rapid increase of free urinary cortisol excretion/24h within one year of observation led to a total bilateral adrenalectomy. Postoperative 5 year follow up examinations. Documentation of the outcome and recovery of clinical signs,symptoms and laboratory findings, discussion about the most appropriate long-term substitution therapy. Familial anamnesis:affected family member was the father (micro nodular bilateral adrenocortical dysplasia), the aunt (pararenal incidentaloma, histologically lipoma) and a cousin (micro nodular adrenocortical dysplasia). Sequential analysis of the menin gene from the patient was negative.The detection of

    We evaluated the effectiveness of radiotherapy combined with chemotherapy in patients with oral squamous cell carcinoma. Therefore, 1042 cases where reviewed in School Dentistry - Osaka Univ. Seven hundred and fifteen were male and three hundred and twenty-seven were female. Ora cancer was affected more male than female patients, with mean age of 582 years old. The tongue was the most common anatomic localization of oral cancer. In tongue, the use of external radiotherapy y combined with brachytherapy and brachytherapy isolated presented better results than chemotherapy combined with external radiotherapy. In buccal mucosa, there was not differences in the treatment's results using external radiotherapy and combined chemotherapy and external radiotherapy. In tongue's floor and upper and jaw gingiva the combined treatment with chemotherapy and external radiotherapy presented better results than isolated external radiotherapy. (author)

  13. Adjuvant chemotherapy in the treatment of intra-oral squamous cell carcinoma

    International Nuclear Information System (INIS)

    Forty five patients with intra-oral squamous cell carcinoma were treated with bleomycin (150 mg) and external irradiation (50 Gy/5 weeks). The response to treatment was observed in 82.2 per cent patients. Another group of 47 patients was irradiated with radical doses of radiotherapy (65 Gy/6 weeks). The response rate was 68.1 per cent. In the former group twenty six patients (57.8 per cent) survived, free from recurrence at five years. The survival rate in the control group was 40.4 per cent (19 out of 47). The toxicity was slightly more pronounced in the patients treated by the combination regime. However, most of them were able to complete the treatment uninterrupted. The literature has been reviewed to evaluate the efficacy of various dosage and fractionation schedules of the bleomycin and radiation, combination. (author). 4 tabs., 12 refs

    Full Text Available Although very rare, medullary thyroid carcinoma (MTC is the most aggressive in differentiated thyroid malignancies. We report a 48-year-old male patient with the diagnosis of MTC, who was monitored for fifteen years and showed no serious adverse events due to long-term chemotherapy. Total thyroidectomy, neck dissection, retrosternal nodule excision and pericardiectomy were performed, and radiotherapy was applied to the neck area. Due to progressive metastatic disease cyclophosphamide, dacarbazine, and vincristine were administrated. He tolerated chemotherapy well, and no severe systemic side effects were detected. He died due to multi-organ failure after fifteen years of diagnosis. The only curative treatment is surgery in MTC, however; radiotherapy, chemotherapy, and embolization may be used for patients for whom surgery cannot be performed. Although success rates of systemic chemotherapy are low, it is a treatment option in the progressive metastatic disease.

  15. Clinical study on external carotid artery infusion (trans-femoral) treatment of recurrent nasopharyngeal carcinoma

    International Nuclear Information System (INIS)

    Objective: To evaluate the effect and safety of external carotid artery infusion treatment of recurrent nasopharyngeal carcinoma (NPC). Methods: 20 cases of recurrent NPC (13 male and 7 female, age 36-65 years, mean 50 years) diagnosed by clinical examination (including nasopharyngoscope), serology (VCA-IgA) and imaging (CT, MR) and treated by external carotid artery infusion (trans-femoral) with adriamycin (or epi-adriamycin), cisplatin (or carboplatin), Pingyangmycin and 5-Fluorouracil. Results: Of all the patients, 8 cases (40%) had a complete response (CR), 7 cases (35%) had a partial response (PR). The overall response rate (CR + PR) was 75%. Cumulative survival rates at 1, 3 years were 90% (18/20), 50%(10/20) respectively. No severe side-effects and complications found. Conclusion: External carotid artery infusion (trans-femoral) should be effective and safe in the treatment of recurrent NPC

    Dose distributions that result from treating a patient with orthovoltage beams are best determined with a treatment planning system that uses the Monte Carlo method, and such systems are not readily available. In the present work, the Monte Carlo method was used to develop a computer code for determining absorbed dose distributions in orthovoltage radiation therapy. The code was used in planning treatment of a patient with a neuroendocrine carcinoma of the maxillary sinus. Two lateral high-energy photon beams supplemented by an anterior orthovoltage photon beam were utilized in the treatment plan. For the clinical case and radiation beams considered, a reasonably uniform dose distribution is achieved within the target volume, while the dose to the lens of each eye is 4 - 8% of the prescribed dose. Therefore, an orthovoltage photon beam, when properly filtered and optimally combined with megavoltage beams, can be effective in the treatment of cancers below the skin, providing that accurate treatment planning is carried out to establish with accuracy and precision the doses to critical structures.

  17. Antiangiogenic treatment in hepatocellular carcinoma: the balance of efficacy and safety

    International Nuclear Information System (INIS)

    Hepatocellular carcinoma (HCC) is a severe complication of advanced liver disease with a worldwide incidence of more than 600,000 patients per year. Liver function, clinical performance status, and tumor size are considered in the Barcelona Clinic Liver Cancer (BCLC) system. While curative treatment options are available for early stages, most patients present with intermediate- or advanced-stage HCC, burdened with a poor prognosis, substantially influenced by the degree of liver-function impairment. Hypervascularization is a major characteristic of HCC, and antiangiogenic treatments are the basis of treatment in noncurative stages, including interventional and pharmacological treatments. Currently, the tyrosine-kinase inhibitor sorafenib is still the only approved drug for HCC. Further improvements in survival in patients with intermediate- and advanced-stage HCC may be anticipated by both multimodal approaches, such as combination of interventional and systemic treatments, and new systemic treatment options. Until now, the Phase III development of other tyrosine-kinase inhibitors in patients with advanced HCC has failed due to minor efficacy and/or increased toxicity compared to sorafenib. However, promising Phase II data have been reported with MET inhibitors in this hard-to-treat population. This review gives a critical overview of antiangiogenic drugs and strategies in intermediate- and advanced-stage HCC, with a special focus on safety

  18. Hyperthermia and PARP1-inhibition for sensitization of radiation and cisplatin treatment of cervical carcinoma cells

    International Nuclear Information System (INIS)

    Ionizing radiation causes single and double strand breaks (SSBs and DSBs). DSBs are among the most critical DNA lesions and can be repaired via either non-homologous end joining (NHEJ) in which PARP1, Ku70 and DNA-PKcs are important, or homologous recombination (HR), where BRCA2 and Rad51 are essential. Hyperthermia disturbs HR by temporary inactivation of BRCA2. Cisplatin disrupts NHEJ and PARP1-inhibitor blocks Poly-(ADP-ribose)polymerase- 1, which is important in SSB repair, NHEJ and backup-NHEJ. Our goal was to investigate the additional effectiveness of hyperthermia and PARP1-inhibition on radiation and/or cisplatin treatment. Cervical carcinoma cells (SiHa) were treated at different temperature levels levels (41.0-43.0℃, PARP1-inhibitor (100 μM; NU1025), gamma-irradiation doses (0-8 Gy) or cisplatin (1'R for 1 h). Clonogenic assays were carried out to measure survival and γH2AX staining was used to visualize DSBs. To elucidate mechanisms of action expression levels of DNA repair proteins BRCA2 and DNA-PKcs were investigated after 42.0℃ (1 h) using western blot. Combined hyperthermia and radiation resulted in an increased number of γH2AX foci as compared to radiation alone. Hyperthermia treatment in combination with cisplatin and PARP1 inhibitor and with radiation and PARP1 inhibitor significantly decreased cell survival. Western blot demonstrated a decreased expression of BRCA2 protein at 30 min after hyperthermia treatment. Adding PARP1-inhibitor significantly improves the effectiveness of combined hyperthermia radiotherapy and combined hyperthermia-cisplatin treatment on cervical carcinoma cells. Hyperthermia affects DNA-DSB repair as is indicated by increased γH2AX foci numbers and decreased BRCA2 expression. (author)

  19. The effect of interventional treatment on the expression of drug-resistance gene in primary lung carcinomas

    International Nuclear Information System (INIS)

    Objective: To study the effect of interventional treatment on the expression of PgP and GST-π in different histopathological types of primary lung carcinoma. Methods: One-hundred and eighteen cases of histopathologically verified primary lung carcinoma were studied. SCLC was found in 26 cases and NSCLC in 92 cases. The non-chemotherapy group had 50 cases, and the interventional treatment group had 68 cases. PgP and GST-π were examined in all specimens with 2-step immunohistochemistry. Results: The positive expression rates of PgP and GST-π were 32.0% and 34.0% in non- chemotherapy group, respectively, 75.0% and 78.6% in interventional treatment with non-embolization group, respectively, and 50.0% and 52.5% in interventional treatment with embolization group, respectively. The positive expression rates of PgP and GST-π had significant difference between non-chemotherapy group and interventional treatment with non-embolization group (P 0.05) . There was a tendency of positive correlation between differentiated degree of carcinoma and the expression of PgP anti GST-π in NSCLC. Conclusion: To detect PgP and GST-π in carcinoma tissue is important and has the instructive significance for chemotherapy of lung carcinoma. The positive rate of multidrug resistant gene is obviously increased in the primary lung carcinoma with bronchial arterial chemotherapy. The inducement to multidrug resistance gene in bronchial arterial embolization with the emulsifying agent of oil anticarcinogen was lower

  20. Avoidance of treatment interruption: an unrecognized benefit of accelerated radiotherapy in oropharyngeal carcinomas?

    International Nuclear Information System (INIS)

    Purpose: To assess the impact of treatment interruption on the potential gain in locoregional control obtained with accelerated radiotherapy (RT) compared with conventionally fractionated RT in patients with oropharyngeal carcinomas. Methods and Materials: 152 patients treated with radical RT for oropharyngeal carcinomas between 1979 and 1996 were retrospectively analyzed. According to the American Joint Committee on Cancer (AJCC) staging system, there were 6/30/43/73 stages I/II/III/IV. Sixty-one patients were treated with a conventional RT schedule (median dose 70 Gy in 35 fractions), and 91 patients with either of two 5/5.5-week accelerated RT schedules (median dose 69.6-69.9 Gy in 41 fractions). Discounting weekends, RT was interrupted for 2 consecutive days or more in 53 patients (median duration 11 days, range 2-97), including 67% of the patients in the conventional RT group and 13% in the accelerated RT group. Median follow-up for surviving patients was 55 months (range 23-230). The Cox proportional hazards model was used for the multivariate analysis of factors influencing locoregional control. Results: In univariate analysis, factors associated with a significant decrease in locoregional control included WHO performance status ≥1, advanced AJCC stages (III and IV), conventional RT fractionation, overall treatment time ≥44 days (median), and RT interruption. In the multivariate analysis, when introduced into the model individually, the three significant therapeutic factors remained significant after adjustment for the forced clinical variables. However, when the three therapeutic factors were introduced together into the model, beside the AJCC stage (P = 0.017), only RT interruption remained a significant independent adverse prognostic factor (P = 0.026). Conclusions: This multivariate analysis highlights the potential negative impact of treatment gaps on locoregional control in oropharyngeal carcinomas. This suggests that treatment interruption may be

    International Nuclear Information System (INIS)

    Purpose. - Hypopharyngeal squamous cell carcinoma is associated to one of the most unfavorable prognosis among the cancers of the head and neck. The purpose of this study is to analyze its therapeutic modalities in the Salah-Azaiz Institute (Tunis) and to compare their results. Patients and method. - This retrospective study concerns 271 hypopharyngeal squamous cell carcinomas, compiled in the Carcinologic Surgery Department of Head and Neck of the Salah-Azaiz Institute over a period of 25 years (from 1977 to 2002). The average age of the patients was of 56 years; sex-ratio was on average of 1.2 (man/woman). The indication of a curative treatment was initially retained for 149 (55%) patients, who were the only ones retained for the analysis of results. Results. - We retained the indication of a protocol including surgery and post-operating radiotherapy for 26.2% of the patients. Post-operation mortality rate was 5.1%; the operating rate of morbidity was 46.2%. For 13.5% of the patients, post-operating radiotherapy was permanently interrupted because of a gradual deterioration of the patients' health in the course of treatment. We retained the indication of exclusive radiotherapy for 59.7% of the patients. The average age was of 56 years and the sex-ratio of 1.2. The external radiotherapy was conventional. Radiotherapy had to be permanently interrupted in progress in 32.6% of cases on account of an deterioration of the patients' health; the rate of morbidity of the radiotherapy was 33.3%. We indicated a protocol of conservation of organ with induction chemotherapy for 21 patients (14.1%). The average age was of 53 years (28-65 years) and sex-ratio (man/woman) of 0.5. The global survival was 25.5% at one year, 18.1% at two years, 11.4% at three years and 7.4% at five years. All the patients selected for chemotherapy died in the course of treatment. The rates of survival in two and five years according to protocols surgery-radiotherapy and exclusive radiotherapy were

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

  3. Evaluating the safety and efficacy of axitinib in the treatment of advanced renal cell carcinoma

    International Nuclear Information System (INIS)

    Axitinib is a tyrosine kinase inhibitor of vascular endothelial growth factor receptor, platelet-derived growth factor receptor-α, and c-kit. Phase I studies demonstrated 5 mg twice daily as the recommended starting dose with notable effects seen in renal cell carcinoma, an observation confirmed in Phase II trials. The trial of comparative effectivess of axitinib versus sorafenib in advanced renal cell carcinoma (AXIS) was an international randomized Phase III study designed for registration purposes, compared axitinib to sunitinib. This trial randomized 723 patients with metastatic kidney cancer to axitinib or sunitinib in the second-line setting and demonstrated a median progression-free survival of 6.7 months for axitinib versus 4.7 months for sorafenib (P<0.0001). Clinical benefit was detected regardless of prior therapy, but no overall survival benefit has been observed. Axitinib is well tolerated without a significant effect on quality of life. The most common grade 3 toxicities are hypertension (16%), diarrhea (11%), and fatigue (11%), with other notable side effects being anorexia, nausea, hand–foot syndrome, and rash. Patients who developed diastolic blood pressure >90 mmHg were noted to have significantly longer median overall survival and overall response rates when compared to normotensive patients. Therefore, the manufacturer recommends escalating the twice-daily dose to 7 mg and 10 mg, as tolerated, if there is no significant increase in blood pressure on treatment. Currently, axitinib is approved for use in the second-line setting for patients with metastatic renal cell carcinoma. Research is ongoing in other disease settings

  6. Treatment results and prognostic factors in 101 men treated for squamous carcinoma of the penis

    International Nuclear Information System (INIS)

    Purpose: This retrospective study was performed to assess the treatment outcome and prognostic factors in 101 men with invasive squamous carcinoma of the penis treated at the Royal Marsden Hospital between 1960-1990. Methods and Materials: The tumor was confined to the glans penis (T1) in 79 patients, 82 were node negative (N0), and two patients had distant metastases at presentation. The histology was Grade 1 (G1) in 36, Grade 2 (G2) in 18, Grade 3 (G3) in 28, and unknown in 19 patients. Node-positive disease was commoner in patients with G3 (p = 0.02) or T2/3/4 tumors (p = 0.007). Treatment for the primary tumor was external beam radiotherapy (EBRT) in 59, interstitial brachytherapy in 13, and partial or total penectomy in 29 patients. The median dose, dose/fraction, and treatment time for EBRT was 60 Gy, 2 Gy/fraction, and 46 days, respectively. Eighty patients received no inguinal node treatment, 13 had EBRT (4 with chemotherapy), and 8 underwent groin dissection at presentation. Results: During a median follow-up of 5.2 years (2 months-22 years), 56 patients died (penile cancer 31, inter-current illness 23 and unknown cause 2), giving 10 year overall and cause-specific survival (CSS) of 39 and 57%, respectively. Adverse prognostic factors for CSS on univariate analysis were G3, ulcerative/fungating or T2/3/4 tumors, node positive, Jackson's Stage 2/3/4, and surgical treatment for the primary. All but the last two were significant independent prognostic factors for CSS on multivariate analysis. Penile or perineal recurrence or residual disease after initial treatment was seen in 36 out of 98 evaluable patients, giving a 10-year local failure rate (LFR) of 45%. Local failure after initial treatment was successfully salvaged in the majority (26 out of 36) of patients with further surgery or radiotherapy, and local control was achieved ultimately in 74 out of 77 T1, 7 out of 12 T2; 3 out of 3 T3, and 3 out of 5 T4 tumors. In the 44 evaluable patients with T1

    The efficacy of radiation therapy for feline advanced cutaneous squamous cell carcinoma was evaluated. A full course radiation therapy protocol was applied to six cats showing single or multiple facial squamous cell carcinomas, in a total of seven histologically confirmed neoplastic lesions. Of the lesions, one was staged as T{sub 1}, and six as T{sub 4} according to WHO staging system of epidermal tumors. The animals were submitted to twelve radiation fractions of 4 Gy each, on a Monday-Wednesday-Friday schedule, and the equipment used was an orthovoltage unit. Energy used was 120 kV, 15 mA and 2 mm aluminum filter. The cats were evaluated during the treatment and 30 and 60 days after the end of the radiation therapy. In this study, 87% of the lesions had complete remission and 13% partial remission to the treatment. Side effects were considered mild according to Veterinary Radiation Therapy Oncology Group Toxicity criteria, and included erythema, epilation and rhinitis. Radiation Therapy was considered safe for feline cutaneous squamous cell carcinoma, leading to mild side effects and can represent a good therapeutic option. (author)

  8. Critical appraisal of pazopanib as treatment for patients with advanced metastatic renal cell carcinoma

    International Nuclear Information System (INIS)

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

    PURPOSE: The administration of interleukin-2 (IL-2) may increase the frequency of peripherally circulating FOXP3-positive regulatory immune cells, thus potentially compromising this treatment option for patients with metastatic renal cell carcinoma. The impact of IL-2-based therapy on the...... accumulation of FOXP3-positive immune cells in the tumor microenvironment in metastatic renal cell carcinoma is unknown. EXPERIMENTAL DESIGN: Baseline (n = 58) and on-treatment (n = 42) tumor core biopsies were prospectively obtained from patients with clear cell metastatic renal cell carcinoma before and...... during IL-2-based immunotherapy. Immunohistochemical expression of FOXP3 was estimated by stereological counting technique and correlated with other immune cell subsets and overall survival. RESULTS: A significant increase in absolute intratumoral FOXP3-positive immune cells was observed comparing...

  10. Comparative observations on intersitial treatment of lower lip carcinoma with radium226 and iridium192

    International Nuclear Information System (INIS)

    Three methods of interstitial radiotherapy of lower lip carcinoma were compared. The material included 155 patients treated with radium by the method of vertical application of Ra226 needles, 445 patients with treatment by the method of transverse application of Ra226 needles and 35 patients treated by the after-loading with iridium192. As comparative criteria the authors accepted: the frequency of recurrences, the duration of radiation-induced reaction, the frequency of necrosis and the cosmetic effect after treatment. In Ra226 treatment after vertical application recurrences developed in 6 out of 155 patients (4%), after translowing iridium192 application no recurrences of neoplasm were observed in any out of 35 cases. Immediate post-radiation reactions lasted on the average 5.8; 6.4; and 7.7 weeks with these 3 methods respectively. Necrosis developed in 6 out of 155 cases (4%) after vertical application, in 23 out of 445 cases (5.2%) after transverse application and in 4 out of 35 cases (11%) after iridium192 application. The best cosmetic effects were obtained with iridium192 with 34.6% of very good results, 65.4% of good results and 0% of scars. The method of interstitial treatment with iridium192 by the after-loading technique provides a better protection of personnel against irradiation as compared with other methods of radium226 treatment.

    Advanced basal cell carcinoma (aBCC) encompasses locally advanced BCC (laBCC) and metastatic BCC (mBCC), two variants of BCC with a limited prevalence worldwide. Treatment of aBCC is still very challenging for the lack of randomized controlled trials/guidelines and the scarcity of available therapeutic options. Based on current data, surgical procedures and radiotherapy are considered the treatments of choice for aBCC although often associated with substantial morbidity and/or deformity. Alternatively, systemic chemotherapy and electrochemotherapy can be used but standardized treatment schedules and randomized clinical trials are not available for both treatments. In recent years, novel tumor-specific and pathogenesis-based molecules have been developed for the treatment of aBCC. A number of clinical trials have recently demonstrated the efficacy and tolerability of vismodegib, the first novel systemic, anti-Smo target cancer therapy for aBCC. Additional molecules currently investigated in phase I-III clinical trials include other Smo antagonists and itraconazole. The contribution of a multidisciplinary team composed of dermatologists, surgeons, oncologists, pathologists, radiologists and radiotherapists is required to deal with the spectrum of issues that emerge from managing patients affected by aBCC.

    The aim of the study was to evaluate the effectiveness of combined treatment of locally advanced lung cancer with the use of neoadjuvant chemotherapy and surgery with the use of pre- and intraoperative photodynamic therapy. 20 patients with IIIa (n=7) and IIIb (n=13) stage of non-small cell lung carcinoma were included. At the time of diagnosis the surgical treatment was decided to abstain because of the trachea invasion in 9 patients, wide mediastinal invasion in 2 patients and contralateral mediastinal lymph nodes metastases in 2 patients; pneumonectomy was not possible due to the poor respiratory function in 7 patients. Neoadjuvant therapy included 3 courses of chemotherapy and endobronchial photodynamic therapy. During the operation, along with the lung resection (pneumonectomy - 15, lobectomy - 5), photodynamic therapy of the resection margins were carried out. No adjuvant treatment was done. Preoperative treatment led to partial regress of the disease in all cases; the goal of surgery was the complete tumor removal. No complications of the photodynamic therapy were observed. 18 surgical interventions were radical and two non-complete microscopically (R1). Postoperative morbidity was 20%, one patient died due to massive gastrointestinal bleeding. The average follow-up period was 18 months: 19 patients were alive, of them 18 with no signs of the disease recurrence. The first experience of the combined use of neoadjuvant chemotherapy and surgery with pre- and intraoperative photodynamic therapy demonstrates safety and efficacy of the suggested treatment tactics.

  13. Thallium-201 single-photon emission tomography in the treatment follow-up of nasopharyngeal carcinoma

    International Nuclear Information System (INIS)

    In order to assess the usefulness of thallium-201 single-photon emission tomography (SPET) in the treatment follow-up of nasopharyngeal carcinoma (NPC), a total of 75 201Tl SPET studies were performed in 18 patients with histologically proven NPC. The findings were compared with those of magnetic resonance imaging (MRI) before and after therapy. Four patients received radiotherapy alone while the other 14 received concurrent chemo-radiotherapy. Treatment response was classified as complete (CR) or partial (PR) based on the findings of MRI and 201Tl SPET. Intense 201Tl uptake by the tumour was seen in all 18 patients before treatment. After treatment, MRI showed seven CRs and 11 PRs, whereas 201Tl SPET showed 13 CRs and five PRs. In 12 patients, the results of 201Tl SPET were in agreement with those of MRI. In six patients MRI showed PR but 201Tl showed CR. Follow-up (mean 10.6 months) MRI and 201Tl SPET studies of these six patients revealed that tumour gradually decreased and finally vanished in three patients. This preliminary study indicates that 201Tl SPET has potential in the assessment of early response to treatment of patients with NPC when compared with MRI. (orig.)

  14. Potential of radioiodine therapy in the treatment of medullary thyroid carcinoma

    International Nuclear Information System (INIS)

    Full text: The effect of I-131 ablation therapy as an adjunct to surgery in the management of patients with medullary thyroid carcinoma (MTC) was studied in our institute. The theme of the study was that among post surgical management of MTC, radioiodine therapy may be considered as a promising adjunct to surgery. No other therapeutic alternative is found to be practical and in recent years there have been several somewhat encouraging reports of treatment of medullary carcinoma of the thyroid with I-131. We have had the opportunity to address this notion on our group of patients. The patients underwent total thyroidectomy and hemithyroidectomy as a procedure. During the year 1988- 2007, 402 Ca thyroid patients were treated with radioiodine in our department of nuclear medicine for ablation of post thyroidectomy remnant tissue. Of these, 14 (3.48%) patients had been suffering from MTC; male to female ratio was 1:1 with mean age of 37.7 yrs ranging from 24-53 yrs. Among these 14 patients, 11(77%) had total thyroidectomy and 3 (23%) hemithyroidectomy. Hemithyroidectomy cases were accepted for ablation, where patients refused second surgery or the cases were inoperable according to the opinion of the concerned Surgeon. They were treated with a mean dose of 89 mCi of I-131 ranging from 75-100 mCi. The post therapy follow up was done at 6 months and 12 months following I- 131 treatments and imaged at 72 hrs. The following parameters were used as success indicator- i) Observation of reduced plasma calcitonin level; ii) Absence of any focal visible uptake in the anterior neck area of thyroid bed. iii) No physical complaints. High success rate and a set of good agreements were obtained from the study. Ablation was achieved in 11 (78%) cases out of 14 patients who were given RIT after thyroidectomy. Reduced/normal plasma calcitonin level was observed in almost in all patients. Out of 14 patients, only 1 patient died of his disease who had extensive metastasis during the

    Full Text Available Thyroid surgeons are becoming increasingly more aware of a histologically distinct subset of thyroid carcinoma whose classification falls between well-differentiated and anaplastic carcinomas with respect to both cell differentiation and clinical behavior. This subtype of tumors has been categorized as poorly differentiated or insular carcinoma, based on its characteristic cell groupings. Although the differentiation of insular carcinoma from other thyroid carcinomas has important prognostic and therapeutic significance, relatively little about insular carcinoma has been published in the otolaryngology literature. In this article, we discuss a case of insular carcinoma of thyroid presenting with concurrent distant metastasis to skull, lung, ribs, and inguinal region with review of the literature. We conclude that insular thyroid carcinoma warrants aggressive management with total thyroidectomy and excision of accessible giant lesion followed by radioactive iodine ablation of any remaining thyroid tissue.

  16. Treatment results for nasopharyngeal carcinoma in the modern era: The Hong Kong experience

    International Nuclear Information System (INIS)

    Purpose: To analyze the treatment results achievable for nasopharyngeal carcinoma in the modern era to identify the key failures for future improvement and to provide an updated baseline for future trials. Methods and materials: The results of 2687 consecutive patients treated at all public oncology centers in Hong Kong during 1996-2000 were retrospectively analyzed. The stage distribution (by American Joint Committee on Cancer and International Union Against Cancer staging system, 1997) was 7% Stage I, 41% Stage II, 25% Stage III, and 28% Stage IVA-B. All patients were irradiated with 6-MV photons and the median total dose was 66 Gy. Only 23% of patients had additional treatment with chemotherapy. Results: The 5-year local, nodal, and distant failure-free rates were 85%, 94%, and 81%, respectively; patients with local failure had significantly higher risk of nodal and distant failures. The 5-year progression-free, overall, and cancer-specific survival rates were 63%, 75%, and 80%, respectively. The presenting stage was the most important prognostic factor for all endpoints: with overall survival decreasing from 90% for Stage I to 58% for Stage IVA-B. The results achieved by the 2070 patients treated by radiotherapy alone were almost identical to that of the whole series, the distant failure-free rate among patients with locoregional control was 89% for Stage I-II and 75% for Stage III-IVB. The 860 patients (32%) staged with magnetic resonance imaging achieved significantly better results than those staged by computed tomography, the overall survival being 93% vs. 83% for Stages I-II, and 72% vs. 63% for Stages III-IVB (p = 0.001). Conclusions: Treatment results for nasopharyngeal carcinoma have substantially improved in the modern era; future trials should be based on updated baseline results. Further reduction of distant failure is important for future breakthrough, particularly for patients with advanced disease

    To report on the safety and efficacy of superselective transcatheter arterial chemoembolization(TACE) of tumor feeding branches originating from the cystic artery for the treatment of hepatocellular carcinoma(HCC). From, May 1955 to, September 1999, eleven HCC patients aged between 38 and 82 (mean, 57.4) years with tumor-feeding branches originating from the cystic artery underwent TACE. In eight, for whom superselection of these branches was possible, TACE was done with the use of Gelform and a mixture of Lipiodol and cisplatin, while for three, for whom superselection was impossible, a mixture of Lipiodol and cisplatin only was used. Immediately after TACE, remnant tumor staining was angiographically evaluated, and tumor response was determined by follow-up CT at one month. After procedure, the development of cholecystitis was clinically. Post-FACE angiography showed remnant tumor staining in one patients who underwent embolization with Gelform and the mixture fo Lipiodol and cisplatin, and in one for whom the mix ture of Lipodol and cisplationly was used. Among the eight for whom Gelfoam and the mixture of Lipiodol and cisplatin was used, one-month follow up CT showed compact Lipiodol uptake in five, partial Lipiodol uptake in three, no change in tumor size in six, increased tumor size in one, and decreased tumor size in one. Among the three for whom the mixture of Lipiodol and cisplatin only was used,one-month follow-up CT showed neither Lipiodol uptake nor change in tumor size in one patient, partial Lipiodol uptake and increased tumor size in one, and compact Lipiodol uptake and decreased tumor size in one. Cholecystitis developed in only one patient who underwent embolization with Gelfoam and the mixture of Lipiodol and cisplatin, but was cured by conservative treatment. Superselective TACE of tumor feeding branches originating from the cystic artery seems to be a safe and effective method for the treatment of hepatocellular carcinoma.

Ultraviolet radiation exposure, including tanning bed use, as well as host factors play a role in its development. The majority of cases are treated and cured with local therapies including surgery. Yet, the health care costs of diagnosis and treatment of BCCs in the US is substantial. In the United States, the cost of nonmelanoma skin cancer care in the Medicare population is estimated to be US$426 million per year. While rare, locally advanced BCCs that can no longer be controlled with surgery and/or radiation, and metastatic BCCs do occur and can be associated with significant morbidity and mortality. Vismodegib (GDC-0449, a smoothened inhibitor targeted at the hedgehog pathway, is the first US Food and Drug Association (FDA-approved agent in the treatment of locally advanced, unresectable, and metastatic BCCs. This class of agents appears to be changing the survival rates in advanced BCC patients, but appropriate patient selection and monitoring are important. Multidisciplinary assessments are essential for the optimal care and management of these patients. For some patients with locally advanced BCC, treatment with a hedgehog inhibitor may eliminate the need for an excessively disfiguring or morbid surgery.

  19. radio embolization of yttrium 90 glass microspheres in treatment of hepatocellular carcinoma

    International Nuclear Information System (INIS)

    Hepatocellular carcinoma (HCC) is a common cancer that typically occurs in the setting of cirrhosis and chronic hepatitis virus infections. HCC is considered currently as global problem; its incidence is expected to increase dramatically by the next few decades. More than 90 % of the accidentally diagnosed patients have non resectable tumor. Portal vein thrombosis, diffuse multifocal liver infiltration and large tumor burden are considered to be a great obstacle in front of the modern lines of treatment, even with Child A liver cirrhosis. Transarterial intrahepatic application of Yttrium-90 glass microspheres may allow effective local ablative treatment of patients with intrahepatic advanced hepatocellular carcinoma (HCC) with or without portal vein thrombosis. The aim of this open-label phase II study was to validate evidence on the safety and efficacy of this treatment in an European cohort of patients with locally advanced HCC such as (large tumor burden, multifocal distribution, portal vein thrombosis). And to assess the response rate according to different approved response assessment guidelines (WHO, RECIST and EASL). Patients and Methods Starting from November 2006 till March 2009, one hundred and eight advanced unresectable HCC patients with and without portal vein thrombosis were included in this prospective study. Yttrium-90 microspheres radiotherapy was performed in a lobar fashion through the right or left hepatic artery. In bilobar disease, right and left liver lobe were treated with 4-6 weeks intervals in between. Response rate was assessed according to different international response assessment criteria (WHO, RECIST and EASL) with sequential computed tomography scans till the last clinical visit or death. The safety of this technique was assessed according to the Common Toxicity Criteria version 3

  20. Glandectomy with preservation of corpora cavernosa in the treatment of penile carcinoma

    2003-01-01

    Full Text Available INTRODUCTION: The objective of this work is to describe a conservative surgical technique as an alternative to classic penile amputations, aiming the local control of the disease, in addition to trying to preserve the patient's sexual function. SURGICAL TECHNIQUE: After a circular incision of the skin around the penis, the subfascial plane is developed until the base of the organ. The dorsal neurovascular bundle and the urethra are isolated in their distal extremities. The neurovascular bundle is sectioned distally. A retrocoronal dissection plane is developed between the glans and the corpora cavernosa. When this stage is complete, the glans is fixed only to the urethra, which is distally sectioned as well. The neurovascular bundle is fixed to the dorsal albuginea. Following the spatulation of the urethra, a neomeatus is created using the overlay skin of the penis. Between January 2001 and July 2002, we employed this technique in 6 patients who had epidermoid carcinoma of the penis, which were limited to the glans, superficial, well or moderately differentiated and measuring up to 3 cm. COMMENTS: Several conservative surgical methods for treatment of carcinoma of the penis aim the organ's preservation, in an attempt of improving the quality of life of patients, however the indexes of local recurrence and failure in disease control are significant. The described technique showed to be safe and effective for disease control, in addition to preserving sexual function in all patients who were treated, representing, thus, a quite appealing conservative surgical alternative in selected cases.

    Current standard of care for muscle-invasive urothelial cell carcinoma (UCC) is surgery along with perioperative platinum-based chemotherapy. UCC is sensitive to cisplatin-based regimens, but acquired resistance eventually occurs, and a subset of tumors is intrinsically resistant. Thus, there is an unmet need for new therapeutic approaches to target chemotherapy-resistant UCC. Yes-associated protein (YAP) is a transcriptional co-activator that has been associated with bladder cancer progression and cisplatin resistance in ovarian cancer. In contrast, YAP has been shown to induce DNA damage associated apoptosis in non-small cell lung carcinoma. However, no data have been reported on the YAP role in UCC chemo-resistance. Thus, we have investigated the potential dichotomous role of YAP in UCC response to chemotherapy utilizing two patient-derived xenograft models recently established. Constitutive expression and activation of YAP inversely correlated with in vitro and in vivo cisplatin sensitivity. YAP overexpression protected while YAP knockdown sensitized UCC cells to chemotherapy and radiation effects via increased accumulation of DNA damage and apoptosis. Furthermore, pharmacological YAP inhibition with verteporfin inhibited tumor cell proliferation and restored sensitivity to cisplatin. In addition, nuclear YAP expression was associated with poor outcome in UCC patients who received perioperative chemotherapy. In conclusion, these results suggest that YAP activation exerts a protective role and represents a pharmacological target to enhance the anti-tumor effects of DNA damaging modalities in the treatment of UCC.

    The purpose of this study was to assess the anatomic and functional outcomes and compare the voice quality in patients affected by T1a glottic carcinoma treated with curative intent with radiotherapy or laser cordectomy. Fifty-seven cases were analysed: 27 after curative radiotherapy and 30 after laser cordectomy. All patients were studied with videolaryngostroboscopy, voice analysis by narrow spectrogram, and vocal parameters (Jitter, Shimmer, noise/harmonic ratio, and diplophonia). Videolaryngostroboscopy showed severe glottic inadequacy in 25% of cases treated with radiation and insufficient compensation 'ventricular band' or 'with arytenoid hyperadduction' in 65% of cases after surgery. Severe dysphonia on the electro-acoustic analysis of voice was observed in 25% of cases after radiation and 70% after laser (p<0.001). Fundamental frequency and vocal parameters showed more favourable results in the radiation group (p<0.001). Voice assessment showed better results after radiotherapy compared with laser cordectomy. Voice outcome should be carefully considered in the treatment decision for T1 glottic carcinoma.

    In a prospective study of 69 patients being treated for oesophageal carcinoma, quality of life was assessed with the Rotterdam Symptom Checklist, a dysphagia score and an activities of daily living questionnaire. Significant correlations were found between the results of the Rotterdam Symptom Checklist, the dysphagia score and most aspects of the activities of daily living questionnaire. Eighteen patients underwent surgery, 43 radiotherapy or intubation, and eight a combination of surgery and other therapy. Patients undergoing surgery were significantly younger and had better scores in all parameters examined before operation, including significantly better scores in 'knowledge and communication' and 'mobility and fatigue'. The dysphagia score fell significantly after intervention both in patients undergoing surgery alone and in those receiving palliative therapy. The activities of daily living questionnaire showed significant improvements in two parameters in the surgical group ('self-care' and 'eating and drinking') and in none of the parameters assessed in the palliation group in 16 weeks. Quality-of-life assessment is useful in assessing quality of care and patient well-being after the diagnosis and treatment of oesophageal carcinoma. PMID:8548241

  4. Voice Quality after Treatment for T1a Glottic Carcinoma - Radiotherapy Versus Laser Cordectomy

    International Nuclear Information System (INIS)

    The purpose of this study was to assess the anatomic and functional outcomes and compare the voice quality in patients affected by T1a glottic carcinoma treated with curative intent with radiotherapy or laser cordectomy. Fifty-seven cases were analysed: 27 after curative radiotherapy and 30 after laser cordectomy. All patients were studied with videolaryngostroboscopy, voice analysis by narrow spectrogram, and vocal parameters (Jitter, Shimmer, noise/harmonic ratio, and diplophonia). Videolaryngostroboscopy showed severe glottic inadequacy in 25% of cases treated with radiation and insufficient compensation 'ventricular band' or 'with arytenoid hyperadduction' in 65% of cases after surgery. Severe dysphonia on the electro-acoustic analysis of voice was observed in 25% of cases after radiation and 70% after laser (p<0.001). Fundamental frequency and vocal parameters showed more favourable results in the radiation group (p<0.001). Voice assessment showed better results after radiotherapy compared with laser cordectomy. Voice outcome should be carefully considered in the treatment decision for T1 glottic carcinoma

  5. The hyperfractionation in the oropharynx carcinomas treatment: stages III and IV

    International Nuclear Information System (INIS)

    From April 1986 until May 1989. 112 patients with stages III and IV oropharynx carcinomas were included in a protocol comparing the use of Hyperfractionation and Conventional Fractionation. The doses were 6600 rad in 33 fractions of 200 rad for the conventional fractionation and 7040 rad in 64 fractions, two fractions of 110 rad per day for the hyperfractionation. As of January 1990 an analysis was performed in 98 patients, with a median follow-up of 14 months. The probability of complete responses in the oropharynx was 74%, with 84% for the hyperfractionation and 64% for the conventional fractionation ( p < 0,05). Survival was improved in 42 months for those patients treated with hyperfractionation: 27% versus 8% (p < 0,05). In patients with lesions out of the base of the tongue and in those with Karnofsky performance status of 50%, 60% and 70%, survival was improved with the use of hyperfractionation (p = 0,02 and p 0,006 respectively. The study demonstrates the superiority of hyperfractionation over the classical fractionation in the treatment of patients with carcinoma of the oropharynx. (author)

    Full Text Available Gastric cancer is one of the most common cancers and most frequent causes of cancer-related deaths in the world. The overall survival rate is 15-20%. Although the incidence is declining, its prognosis remains poor. The etiological factors and pathogenesis of gastric cancer are not yet fully understood. The integrated research in molecular pathology clarified the details of genetic and epigenetic abnormalities of cancer-related genes in the course of development and progression of gastric cancer. Although epidemiological evidences indicate that environmental factors play a major role in the carcinogenesis, the role of immunological, genetic and immunogenetic factors are thought to contribute to etiopathogenesis of gastric carcinoma. In addition to better understanding of pathogenesis of gastric cancer, the incidence, diagnostic studies and the therapeutic options have also undergone important changes in the last decade. There is ongoing debate regarding the role of adjuvant treatment. In advanced disease, palliation of symptoms, rather than cure, is the primary goal of patient management. Several combination therapies have been developed and have been examined in phase III trials; however, in most cases, they have failed to demonstrate a survival advantage over the reference arm. This review summarizes the newer concepts of molecular biology on gastric carcinogenesis and the new important recommendations for the management of patient with gastric carcinoma.

  7. Merkel cell carcinoma in patients on long-term immunosuppressive treatment

    International Nuclear Information System (INIS)

    Merkel cell carcinoma is a rare form of skin cancer of neuroendocrine origin that has been described as one of the most aggressive cutaneous malignancies. The annual incidence is estimated to be 0.23 per 100,000 in the white population. Most cases occur in elderly people, the average age being 69 years. MCC is most common in sun-exposed areas, with nearly 50% of lesions developing within the head and neck. It typically appears as a red-blue nodule with a shiny surface, often with overlying telangiectasia. One of the most important etiological factors is long-term immunosuppression, mainly in organ transplant recipients. Nowadays it is speculated that previously unknown polyoma virus - Merkel cell polyoma virus (MCV) - can be another probable etiologic agent of the disease. This paper presents the latest data on the pathogenesis of Merkel cell carcinoma and analyses the differences between MCC occurring in patients undergoing immunosuppressive treatment and MCC developing in immunocompetent patients.

    Full Text Available Long-term outcome after operation for benign functional adrenal tumours [aldosteronoma (PA, subclinical (SCS or clinical Cushing ́s syndrome (CS] has not been reported extensively, especially not in the era of robotic-assisted laparoscopic surgery why pheochromocytomas has not been included in the group of benign functional masses? We have excluded pheocromocytoma because it is well known that it is very difficult to distinguish between malignant and benign pheocromocytomas. Since our aim was to evaluate benign lesions, we excluded pheocromocytomas. The purpose of this study was to investigate the clinical outcome for patients having undergone adrenalectomy for non-malignant clinical or subclinical functional adrenocortical tumors. The records of 65 patients with benign functional adrenocortical tumors treated with laparoscopic adrenalectomy (80% robotic assisted were surveyed retrospectively. Clinical and biochemical data were evaluated at baseline and follow-up data was collected by a survey distributed to referring endocrinology centers. Cure was defined both in objective measurements and in the subjective validation of the endocrinologists referring the patients for surgery. According to our definition, 83% of patients with PA were either cured (normotension without anti-hypertensive medication, or improved (better blood pressure control with equal or fewer medications. For CS, 89% of patients were cured (biochemical normalization and lack of or significant improvement in co-morbidities. With the same definition, 73% of SCS patients were cured. The endocrinologists considered 86% of PA patients, 100% of CS and 64% of SCS patients as cured. Complications were few and there was no mortality. Robotic assisted adrenalectomy provides safe and effective treatment for PA, CS and SCS. Our objective definition of cure matched the assessment of cure of the endocrinologists in patients with PA and CS.

    The occurrence of stress-inducing factors in captive crocodilians is a concern, since chronic stress can negatively affect animal health and reproduction, and hence production. Monitoring stress in wild crocodiles could also be beneficial for assessing the state of health in populations which are potentially threatened by environmental pollution. In both cases, a non-invasive approach to assess adrenocortical function as a measure of stress would be preferable, as animals are not disturbed during sample collection, and therefore sampling is feedback-free. So far, however, such a non-invasive method has not been established for any crocodilian species. As an initial step, we therefore examined the suitability of two enzyme-immunoassays, detecting faecal glucocorticoid metabolites (FGMs) with a 11β,21-diol-20-one and 5β-3α-ol-11-one structure, respectively, for monitoring stress-related physiological responses in captive Nile crocodiles (Crocodylus niloticus). An adrenocorticotropic hormone (ACTH) challenge was performed on 10 sub-adult crocodiles, resulting in an overall increase in serum corticosterone levels of 272% above the pre-injection levels 5h post-injection. Saline-treated control animals (n=8) showed an overall increase of 156% in serum corticosterone levels 5h post-administration. Faecal samples pre- and post-injection could be obtained from three of the six individually housed crocodiles, resulting in FGM concentrations 136-380% above pre-injection levels, always detected in the first sample collected post-treatment (7-15 days post-injection). FGM concentrations seem comparatively stable at ambient temperatures for up to 72 h post-defaecation. In conclusion, non-invasive hormone monitoring can be used for assessing adrenocortical function in captive Nile crocodiles based on FGM analysis. PMID:25066028

  10. Treatment of patients with Huerthle cell thyroid carcinoma using [Lu-177-DOTAO, Tyr3]octreotate

    International Nuclear Information System (INIS)

    Full text of publication follows. Aim: Huerthle cell thyroid carcinoma (HCTC) is a variant of follicular thyroid carcinoma. Although radioiodine (I-131) is given for ablation of the thyroid remnant to enable serum thyroglobulin levels for follow-up, it is rarely used for the treatment of residual or metastatic disease, related to the Huerthle cell tumour's poor capacity of taking up radioiodine. Since thyroid tumour cells express somatostatin receptors, peptide receptor radionuclide therapy using radiopharmaceuticals such as [Lu-177-DOTA0,Tyr3]octreotate (Lu-177-octreotate) has been proposed as a potential treatment option. Materials and Methods: 15 patients with pathology proven HCTC treated with Lu-177-octreotate between January 2000 and April 2012 were studied. CT or MRI scans were analysed using SWOG criteria for response outcome. Thyroglobulin levels were analysed and a decrease of more than 50% was considered as a significant biochemical response. All patients had received radioiodine to ablate the thyroid remnant. Six patients received an additional treatment dose of I-131 (total cumulative dose range: 0.7 to 14.8 GBq I-131). Results: Acute side effects such as nausea, vomiting, pain, and hair loss were present during 22%, 2%, 8% and 27% of all administrations respectively. WHO grade 3 bone marrow toxicity for both platelets and leukocytes was present in 2% of all treatment cycles. No long-term side effects such as myelodysplasia or kidney failure were found during a median follow-up of 25 months (range 2-119 months). Twelve patients received the intended cumulative dose (22.2-29.6 GBq) of Lu-177-octreotate whereas 3 did not, due to persisting thrombocytopenia, concomitant cardiac atrial fibrillation, or to the diagnosis of rectal adenocarcinoma as a second primary tumour. In 11 out of the 12 remaining patients sufficient follow-up data were available for evaluation. Four (36%) patients had a partial response (PR) at 3 months after the last treatment

    We aimed to develop and validate a simplified, novel quantification method for radioiodine whole-body scans (WBSs) as a predictor for the treatment response in differentiated thyroid carcinoma (DTC) patients with distant metastasis. We retrospectively reviewed serial WBSs after radioiodine treatment from 2008 to 2011 in patients with metastatic DTC. For standardization of TSH simulation, only a subset of patients whose TSH level was fully enhanced (TSH > 80 mU/l) was enrolled. The radioiodine scan index (RSI) was calculated by the ratio of tumor-to-brain uptake. We compared correlations between the RSI and TSH-stimulated serum thyroglobulin (TSH{sub sT}g) level and between the RSI and Tg reduction rate of consecutive radioiodine treatments. A total of 30 rounds of radioiodine treatment for 15 patients were eligible. Tumor histology was 11 papillary and 4 follicular subtypes. The TSH{sub sT}g level was mean 980 ng/ml (range, 0.5–11,244). The Tg reduction rate after treatment was a mean of −7 % (range, −90 %–210 %). Mean RSI was 3.02 (range, 0.40–10.97). RSI was positively correlated with the TSH{sub sT}g level (R2 = 0.3084, p = 0.001) and negatively correlated with the Tg reduction rate (R2 = 0.2993, p = 0.037). The regression equation to predict treatment response was as follows: Tg reduction rate = −14.581 × RSI + 51.183. Use of the radioiodine scan index derived from conventional WBS is feasible to reflect the serum Tg level in patients with metastatic DTC, and it may be useful for predicting the biologic treatment response after radioiodine treatment.

  12. A clinical staging system and treatment guidelines for maxillary osteoradionecrosis in irradiated nasopharyngeal carcinoma patients

    International Nuclear Information System (INIS)

    Purpose: To develop a clinical staging system for maxillary osteoradionecrosis (ORN) in irradiated nasopharyngeal carcinoma (NPC) patients. Methods and Materials: The data of maxillary ORN cases among 1,758 irradiated NPC patients were analyzed. A staging system based on the degrees of bone exposure (E), infection (I), and bleeding (B) was developed. Correlations between various clinical parameters and stages of maxillary ORN and relationships between treatment modalities and outcomes at each stage were evaluated. Cumulative success of treatment and risk factors that affect treatment outcomes were analyzed. Results: The incidence of maxillary ORN was 2.7% (48/1,758). TNM stage of NPC (p < 0.001), radiation dose (p = 0.029), and tooth extraction (p < 0.001) appeared to have significant influences on disease severity. Success rates between conservative therapy and surgical treatment were not significantly different for Stage I ORN but differed significantly for Stage II (p = 0.013) and Stage III (p = 0.008) lesions. Grade 3 infection and bleeding significantly jeopardized treatment success (p = 0.043 and 0.015, respectively). The risk ratios of treatment failure for Grade 3 infection and bleeding were 2.523 (p = 0.034) and 3.141 (p = 0.027), respectively. Conclusions: More serious maxillary ORN tended to occur in cases with more advanced NPC, higher radiation dose, and history of tooth extraction. Surgical treatment was usually required in Stage II and III ORN. The grades of infection and bleeding are important factors in guidance of treatment and prediction of outcomes

    Many endocrine systems are sensitive to external changes in the environment. Both the pituitary adrenal and pituitary gonadal systems are affected by stress including centrifugation stress. The effect of centrifugation on the pituitary gonadal and pituitary adrenocortical systems was examined by measuring the gonadal and adrenal steroids in the plasma and brain following different duration and intensity of centrifugation stress in rats. Two studies were completed and the results are presented. The second study was carried out to describe the developmental changes of brain, plasma and testicular testosterone and dihydrotestosterone in Sprague Dawley rats so that the effect of centrifugation stress on the pituitary gonadal syatem could be better evaluated in future studies.

    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

    Hepatocellular carcinoma(HCC)is one of the 10 most common cancers worldwide.There is no ideal treatment for HCC yet and many researchers are trying to improve the effects of treatment by changing therapeutic strategies.As the majority of human cancers seem to exhibit either abnormal p53 gene or disrupted p53 gene activation pathways,intervention to restore wild-type p53 (wt-p53)activities is an attractive anti-cancer therapy including HCC.Abnormalities of p53 are also considered a predisposition factor for hepatocarcinogenesis.p53 is frequently mutated in HCC.Most HCCs have defects in the p53-mediated apoptotic pathway although they carry wt-p53.High expression of p53 in vivo may exert therapeutic effects on HCC in two aspects:(1)High expression of exogenous p53 protein induces apoptosis of tumor cells by inhibiting proliferation of cells through several biologic pathways and(2)Exogenous p53 renders HCC more sensitive to some chemotherapeutic agents.Several approaches have been designed for the treatment of HCC via the p53 pathway by restoring the tumor suppression function from inactivation,rescuing the mutated p53 gene from instability,or delivering therapeutic exogenous p53.Products with p53 status as the target have been studied extensively in vitro and in vivo.This review elaborates some therapeutic mechanisms and advances in using recombinant human adenovirus p53 and oncolytic virus products for the treatment of HCC.

    Squamous cell carcinoma arises from multiple anatomic subsites in the head and neck region. The risk factors for development of cancers of the oral cavity, oropharynx, hypopharynx, and larynx include tobacco exposure and alcohol dependence, and infection with oncogenic viruses is associated with cancers developing in the nasopharynx, palatine, and lingual tonsils of the oropharynx. The incidence of human papillomavirus-associated oropharyngeal cancer is increasing in developed countries, and by 2020, the annual incidence could surpass that of cervical cancer. The treatment for early-stage squamous cell cancers of the head and neck is generally single modality, either surgery or radiotherapy. The treatment for locally advanced head and neck cancers is multimodal, with either surgery followed by adjuvant radiation or chemoradiation as indicated by pathologic features or definitive chemoradiation. For recurrent disease that is not amenable to a salvage local or regional approach and for metastatic disease, chemotherapy with or without a biological agent is indicated. To date, molecular testing has not influenced treatment selection in head and neck cancer. This review will focus on the changing epidemiology, advances in diagnosis, and treatment options for squamous cell cancers of the head and neck, along with data on risk stratification specific to oropharyngeal cancer, and will highlight the direction of current trials.

    Radioactive iodine (/sup 131/I) was used in the treatment of a 12-year-old female dog with hyperthyroidism resulting from a large, unresectable (and metastatic) thyroid carcinoma associated with signs of severe inspiratory stridor and dyspnea. Hyperthyroidism was diagnosed on the basis of clinical signs (polyuria, polydipsia, polyphagia, weight loss, nervousness) and high basal serum thyroxine (T4) concentrations, as well as thyroid radioiodine kinetic studies that showed a high radioiodine uptake into the thyroid (% thyroid uptake) and markedly increased serum concentrations of protein-bound iodine-131 (PB/sup 131/I) after /sup 131/I tracer injection. Thyroid imaging revealed diffuse radionuclide accumulation by the tumor, which involved both thyroid lobes. The dog was treated with three large doses of radioiodine (/sup 131/I), ranging from 60 to 75 mCi, given at intervals of 5 to 7 months. The dog became euthyroid, and the size of the tumor decreased by approximately 25% after each /sup 131/I treatment, improving the severe inspiratory stridor and dyspnea, but both the hyperthyroid state and breathing difficulty recurred within a few months of each treatment. The dog was euthanatized 5 months after the last treatment because of progressive tracheal compression and pulmonary metastasis.

  18. Everolimus – a new approach in the treatment of renal cell carcinoma

    International Nuclear Information System (INIS)

    With the increasing understanding of the biology of the disease and the development of targeted therapy, there has been a paradigm shift in the treatment of clear cell metastatic renal cell carcinoma (mRCC). Traditionally patients with metastatic RCC have been treated with immunotherapy which has limited efficacy. The multikinase inhibitors sunitinib, sorafenib and pazopanib, the VEGF antibody bevacizumab in combination with interferon and the mTOR inhibitor temsirolimus have all been shown to prolong progression-free survival in phase III studies. Here we review another mTOR inhibitor, everolimus (Afinitor®; Novartis, USA) which was approved in March 2009 by the US FDA for treatment of targeted-therapy refractory metastatic renal cell cancer. The phase III study of everolimus (the RECORD study) was terminated early after a significant difference in efficacy was noted in the treatment arm with everolimus (progression-free survival of 4.0 months in patients on the treatment arm vs 1.9 months in the placebo arm). The most common adverse events were stomatitis, pneumonitis, fatigue and infections. We review Phase I–III data with a particular emphasis on safety data and patient focused outcomes

    Hepatocellular carcinoma (HCC) is a major health problem worldwide, affecting more than 600,000 new patients per year. Curative treatments are available in a small percentage of patients, while most of them present in stages requiring locoregional treatments such as thermoablation, transarterial chemoembolization, and/or radioembolization. These therapies result in specific imaging features that the general radiologist has to be aware of in order to assess the response to treatment and to correctly manage the follow-up of treated patients. Multiphasic helical computed tomography has become a popular imaging modality for detecting hypervascular tumors and characterizing liver lesions. On this basis, many staging and diagnostic systems have been proposed for evaluating response to all different existing strategies. Radiofrequencies and microwaves generate thermoablation of tumors, and transarterial chemoembolization exploits the double effect of the locoregional administration of drugs and embolizing particles. Eventually radioembolization uses a beta-emitting isotope to induce necrosis. Therefore, the aim of this comprehensive review is to analyze and compare CT imaging appearance of HCC after various locoregional treatments, with regard to specific indications for all possible procedures.

    Evidence of relative effectiveness of local treatments for hepatocellular carcinoma (HCC) is scanty. We investigated, in a retrospective cohort study, whether surgical resection, radiofrequency ablation (RFA), percutaneous ethanol injection (PEI), and transarterial embolization with (TACE) or without (TAE) chemotherapy resulted in different survival in clinical practice. All patients first diagnosed with HCC and treated with any locoregional therapy from 1998 to 2002 in twelve Italian hospitals were eligible. Overall survival (OS) was the unique endpoint. Three main comparisons were planned: RFA versus PEI, surgical resection versus RFA/PEI (combined), TACE/TAE versus RFA/PEI (combined). Propensity score method was used to minimize bias related to non random treatment assignment. Overall 425 subjects were analyzed, with 385 (91%) deaths after a median followup of 7.7 years. OS did not significantly differ between RFA and PEI (HR 1.11, 95% CI 0.79–1.57), between surgery and RFA/PEI (HR 0.95, 95% CI 0.64–1.41) and between TACE/TAE and RFA/PEI (HR 0.88, 95% CI 0.66–1.17). 5-year OS probabilities were 0.14 for RFA, 0.18 for PEI, 0.27 for surgery, and 0.15 for TACE/TAE. No locoregional treatment for HCC was found to be more effective than the comparator. Adequately powered randomized clinical trials are still needed to definitely assess relative effectiveness of locoregional HCC treatment. PMID:22654628

    AIM: To prospectively evaluate the efficacy and safety of partial splenic embolization (PSE) combined with transcatheter hepatic arterial chemoembolization (TACE)in treatment of hepatocellular carcinoma (HCC).METHODS: Fifty patients suffering from primary HCC associated with hypersplenism caused by cirrhosis were randomly assigned to 2 groups: group A receiving PSE combined with TACE (n = 26) and group B receiving TACE alone (n = 24). Follow-up examinations included calculation of peripheral blood cells (leukcytes,platelets and red blood cells) and treatment-associated complications.RESULTS: Prior to treatment, there was no significant difference in sex, age, Child-Pugh grade, tumor diameter,mass pathology type and peripheral blood cell counts between the 2 groups. After treatment, leukocyte and platelet counts were significantly higher in group A during the 3-mo follow-up period (P < 0.05), but lower in group B (P < 0.05). Severe complications occurred in 3 patients (11.5%) of group A and in 19 patients (79.2%) of group B (P < 0.05), and there was no significant difference in symptoms of post-embolization syndrome,including abdominal pain, fever, mild nausea and vomiting between the 2 groups (P > 0.05).CONCLUSION: PSE combined with TACE is more effective and safe than TACE alone for patients with HCC associated with hypersplenism caused by cirrhosis.

    Treatment options for localized resectable basal cell carcinoma (BCC) include micrographically controlled surgery, simple excision, curettage, laser ablation, cryosurgery, imiquimod, 5-fluorouracil, photodynamic therapy and radiotherapy. The aim of this study was to assess the preferences of patients with BCC for outcome (cure and recurrence rate, cosmetic outcome, risk of temporary and permanent complications) and process attributes (type of therapy, treatment location, anaesthesia, method of wound closure, duration of wound healing, out-of-pocket costs) of these treatments with conjoint analysis. Participants (n = 124) attached greatest importance to recurrence rate (relative importance score (RIS) = 17.28), followed by cosmetic outcome (RIS = 16.90) and cure rate (RIS = 15.02). Participants with BCC on the head or neck were particularly interested in cosmetic outcome. Those with a recurrence were willing to trade risk of recurrence, treatment location and duration of wound healing for a better cosmetic result. In summary, participants particularly valued cure and cosmetic outcome, although preferences varied with individual and tumour-associated characteristics. PMID:26537095

    Full Text Available As the fifth most common cancer in men and the eighth most common cancer in women, hepatocellular carcinoma (HCC is the leading cause of cancer-related deaths worldwide, with standard chemotherapy and radiation being minimally effective in prolonging survival. Virus hepatitis, particularly HBV and HCV infection is the most prominent risk factor for HCC development. Mammalian target of rapamycin (mTOR pathway is activated in viral hepatitis and HCC. mTOR inhibitors have been tested successfully in clinical trials for their antineoplastic potency and well tolerability. Treatment with mTOR inhibitor alone or in combination with cytotoxic drugs or targeted therapy drug scan significantly reduces HCC growth and improves clinical outcome, indicating that mTOR inhibition is a promising strategy for the clinical management of HCC.

  5. Effect of combined treatment with radiation therapy and peplomycin on the carcinoma of the oral cavity

    International Nuclear Information System (INIS)

    One hundred and seventeen patients with squamous cell carcinoma of the oral cavity were treated by radiation therapy combined with peplomycin analized the results. The complete regression (CR) rate after radiation (30 Gy/3 wks) combined with peplomycin (45 mg/3 wks) was 42 % (49/117). Of these 49 patients with CR, 16 patients were followed without additional treatment 12 patients (75 %) achieved local control at 2 years or more. Overall two-year local control rate was 85 % (hard palate : 100 %, mouth floor : 95 %, tongue : 84 %, lower gingiva : 73 %, upper gingiva : 82 %, cheek mucosa : 74 %). Three-year survival rate was 76 % (tongue : 75 %, lower gingiva : 75 %, mouth floor : 70 %, upper gingiva : 82 %, cheek mucosa : 87 %, hard palate : 67 %). (author)

    A case is presented of a patient with a skin basosquamous cell carcinoma of the frontal region infiltrating the cerebral tissue and with a widespread unresectable regional metastatic ulceration of the left parotid region. The patient underwent combined palliative treatment: surgical coverage of the ulceration by means of a pectoralis mayor flap transposition and radiotherapy. After 18 months of follow-up, no signs of tumour progression were noted, the patient is currently free from pain, no increase in trismus was seen, and a slight gain in weight was recorded. Unresectable cancer is mainly treated by concurrent chemoradiation; radiotherapy, however, is contraindicated in deep neoplastic ulcerations with exposure of large vessels. The data reported suggest that surgical coverage of an unresectable neoplastic ulcer is feasible, and combined with early administration of radiation permits a palliative approach in an otherwise untreatable condition.

    Hepatocellular carcinoma(HCC) is one of the major malignant diseases in many healthcare systems. The growing number of new cases diagnosed each year is nearly equal to the number of deaths from this cancer. Worldwide, HCC is a leading cause of cancerrelated deaths, as it is the fifth most common cancer and the third most important cause of cancer related death in men. Among various risk factors the two are prevailing: viral hepatitis, namely chronic hepatitis C virus is a well-established risk factor contributing to the rising incidence of HCC. The epidemic of obesity and the metabolic syndrome, not only in the United States but also in Asia, tend to become the leading cause of the long-term rise in the HCC incidence. Today, the diagnosis of HCC is established within the national surveillance programs in developed countries while the diagnosis of symptomatic, advanced stage disease still remains the characteristic of underdeveloped countries. Although many different staging systems have been developed and evaluated the BarcelonaClinic Liver Cancer staging system has emerged as the most useful to guide HCC treatment. Treatment allocation should be decided by a multidisciplinary board involving hepatologists, pathologists, radiologists, liver surgeons and oncologists guided by personalized-based medicine. This approach is important not only to balance between different oncologic treatments strategies but also due to the complexity of the disease(chronic liver disease and the cancer) and due to the large number of potentially efficient therapies. Careful patient selection and a tailored treatment modality for every patient, either potentially curative(surgical treatment and tumor ablation) or palliative(transarterial therapy, radioembolization and medical treatment, i.e., sorafenib) is mandatory to achieve the best treatment outcome.

    A 58-year-old woman was referred to our hospital for Cushingoid features and diagnosed as adrenal Cushing's syndrome due to a right adrenocortical mass (60 × 55 mm). The mass was composed of three different tumors; the first one was homogeneously lipid-poor neoplasm measuring 20 × 13 mm located at the most dorsal region, the second one was heterogeneous and lipid-rich tumor containing multiple foci of calcification measuring 50 × 32 mm located at the central region, and the last one was heterogeneous harboring dilated and tortuous vessels and lipid-poor one measuring 35 × 18 mm at the most ventral region of the adrenal gland. A right adrenalectomy was subsequently performed by open surgery. Macroscopic and microscopic analyses revealed that all three tumors were adrenocortical adenomas; the first one represents a pigmented adrenocortical adenoma, the second one adrenocortical adenoma associated with degeneration, and the third one adrenocortical adenoma harboring extensive degeneration. Immunohistochemical analysis of the steroidogenic enzymes also revealed that all of the tumors had the capacity of synthesizing cortisol. This is a very rare case of Cushing's syndrome caused by multiple adrenocortical adenomas including a pigmented adenoma. Immunohistochemical analysis of steroidogenic enzymes contributed to understanding of steroidogenesis in each of these three different adrenocortical adenomas in this case. PMID:26961704

    2004-12-01

    Background and purpose: to date none of the studies examined the feasibility and efficacy of interstitial high-dose-rate (HDR) brachytherapy in the treatment of carcinoma of the tongue base. Therefore the aim of this study was to contribute to this issue. Patients and methods: between 1992 and 2000 37 patients (mean age 55 years) with T1-4 and NO-3 carcinoma of the base of tongue were presented. Neck dissection was carried out in twelve cases (32%). 30 patients with advanced stage received brachytherapy boost after 50-66.5 Gy (mean, 60 Gy) locoregional external beam irradiation (EBI) and 7 patients with early stage (T1-2, NO) were managed locally with wide tumor excision and sole brachytherapy. 4 of them underwent neck dissection and the others were subjected to 50 Gy regional EBI. The mean dose of boost and sole brachytherapy was 18 Gy and 28 Gy, respectively. Results: the median follow-up time for surviving patients was 51 months. The 7 sole brachytherapy patients are living with no evidence of disease. For patients treated with EBI and brachytherapy boost, the 5-year actuarial rate of local, locoregional recurrence-free and overall survival was 60%, 52% and 46%, respectively. For all patients in univariate analysis larger tumor size (T4 vs. T1-3) was significant negative predictor of local (RR: 7.23) and locoregional control (RR: 3.87), but nodal involvement was not. Delayed soft tissue ulceration and osteoradionecrosis occurred in 4 (13%) EBI and brachytherapy treated patients. None of the sole brachytherapy patients experienced severe late radiation toxicity. Conclusion: EBI combined with interstitial HDR brachytherapy boost result in acceptable local tumor control with low incidence of late side effects in patients with advanced disease. Fractionated sole HDR brachytherapy following tumor excision is a feasible treatment option for patients with early stage cancer and gives excellent local results. (orig.)

    Background Nasopharyngeal carcinoma (NPC) is a squamous-cell carcinoma especially prevailing among the natives of southern China.The regimen of concurrent chemoradiotherapy (CCRT) that include platinum and 5-fluorouracil (5-FU)is considered to be the standard treatment for NPC.However,its clinical use is limited by its toxicity.Our purpose was to evaluate the efficacy and safety of the regimen of CCRT with taxanes and platinum versus the regimen of CCRT with 5-FU and platinum in NPC treatment.Methods Medline,the Cochrane library,and the Chinese medical literature database were searched for eligible studies.Meta-analysis was performed using Review Manager (Version 5.2).Results Six random controlled trials (RCTs) including 514 patients met our criteria.Meta-analysis showed that the regimen of CCRT with taxanes and platinum had an improved significant difference in complete remission (CR) and less incidence rate in adverse reactions such as gastrointestinal impairment grades Ⅲll-Ⅳ,liver and kidney impairment grades Ⅰ-Ⅱ,and radiodermatitis grades Ⅲ-Ⅳ versus the conventional regimen of CCRT with 5-FU and platinum,while the long-term effectiveness rate of overall survival,Iocoregional failure-free survival,or distant metastasis failure-free survival between the two groups was therapeutic equivalence.Conclusions The regimen of CCRT with taxanes and platinum in NPC therapy may be more efficient and safe compared to the conventional modality of 5-FU and platinum in CCRT.However,we need more high-quality studies of multi-center and randomized double-blind clinical trials to further compare,analyze,and confirm the findings.

  11. Treatment of esophagorespiratory fistulas associated with esophageal carcinoma: effectiveness and problems of a modified gianturco stent

    International Nuclear Information System (INIS)

    To evaluate the effectiveness and problems of Gianturco stent for treatment of esophagorespiratory fistulas caused by esophageal carcinoma. In a 6-year period, we have treated 95 patients of esophageal carcinomas with silicone-covered modified Gianturco stent. Among those patients, ten had an esophagorespiratory fistula. We retrospectively analyzed the effect of stent for the occlusion of esophagorespiratory fistula, food intake capacity of patients, clinical and procedural problems of the stent. After procedure, all fistulas were occluded successfully. Of the 10 patients, two could swallow all kinds of food, four most of foods, three soft foods, and one only liquid foods. In one patient, the fistula was reopened probably resulting from the reflux due to the presence of another lesion in the distal esophagus at 1 week after procedure. Two patients complained of dyspnea the to tracheal compression by the proximal tip of the stent and tracheal invasion of tumor after 4 and 11 weeks. In one patient, fistula was recurred due to tumor overgrowth on proximal and distal portion after 24 weeks. The fistulas recurred from the tumor overgrowth of reflux were successfully treated with another esophageal stent. The tracheal compression by the proximal tip of the stent and invasion by esophageal cancer was treated with tracheal stent and radiation therapy. Insertion of silicone-covered modified Gianturco stent was an effective method for the palliative treatment of esophagorespiratory fistula caused by esophageal cancer. Simultaneous use of tracheal stent is also recommended in patients with tracheal compression by the proximal tip of the stent and invasion by esophageal cancer

  12. Combination chemotherapy including high dose methotrexate and radiotherapy, in the treatment of small cell carcinoma of the lung

    International Nuclear Information System (INIS)

    Twenty-nine (88%) of thirty-three patients who were treated with multiple drug chemotherapy, including high dose methotrexate, and radiotherapy for small cell carcinoma of the lung showed significant improvement in their clinical condition and quality of life. Treatment was well tolerated and toxicity acceptable. Cerebral metastases were not detected in any patient on presentation and only developed in three patients (9%). Little information exists regarding the use of high dose methotrexate in small cell carcinoma of the lung. There is no evidence, on the data available, that high dose methotrexate is any more effective than conventional doses. (author)

    A 31-year-old woman was referred to our hospital with symptoms of hypertension and bilateral adrenocortical masses with no feature of Cushing syndrome. The serum aldosterone/renin ratio was elevated and the saline loading test showed no suppression of the plasma aldosterone level, consistent with a diagnosis of primary hyperaldosteronism. Overnight and low-dose dexamethasone suppression tests showed no suppression of serum cortisol, indicating a secondary diagnosis of subclinical Cushing syndrome. Adrenal vein sampling during the low-dose dexamethasone suppression test demonstrated excess secretion of cortisol from the left adrenal mass. A partial right adrenalectomy was performed, resulting in normalization of blood pressure, hypokalemia, and high aldosterone level, implying that the right adrenal mass was the main cause of the hyperaldosteronism. A total adrenalectomy for the left adrenal mass was later performed, resulting in a normalization of cortisol level. The final diagnosis was bilateral adrenocortical adenomas, which were secreting aldosterone and cortisol independently. This case is the first report of a concurrent cortisol-producing left adrenal adenoma and an aldosterone-producing right adrenal adenoma in Korea, as demonstrated by adrenal vein sampling and sequential removal of adrenal masses.

    Mother squirrel monkeys stop carrying infants at earlier ages in high-demand (HD) conditions where food is difficult to find relative to low-demand (LD) conditions. To characterize these transitions in psychosocial development, from 10- to 21-weeks postpartum we collected measures of behavior, adrenocortical activity, and social transactions coded for initiator (mother or infant), goal (make-contact or break-contact), and outcome (success or failure). Make-contact attempts were most often initiated by HD infants, but mothers often opposed these attempts and less than 50% were successful. Break-contact attempts were most often initiated by LD infants, but mothers often opposed these attempts and fewer LD than HD infant break-contact attempts were successful. Plasma levels of cortisol were significantly higher in HD than LD mothers, but differences in adrenocortical activity were less consistent in their infants. HD and LD infants also spent similar amounts of time nursing on their mothers and feeding on solid foods. By rescheduling some transitions in development (carry-->self-transport), and not others (nursing-->self-feeding), mothers may have partially protected infants from the immediate impact of an otherwise stressful foraging task.

  15. Proton Beam Therapy for Hepatocellular Carcinoma: A Comparison of Three Treatment Protocols

    International Nuclear Information System (INIS)

    Background: Our previous results for treatment of hepatocellular carcinoma (HCC) with proton beam therapy revealed excellent local control with low toxicity. Three protocols were used to avoid late complications such as gastrointestinal ulceration and bile duct stenosis. In this study, we examined the efficacy of these protocols. Methods and Materials: The subjects were 266 patients (273 HCCs) treated by proton beam therapy at University of Tsukuba between January 2001 and December 2007. Three treatment protocols (A, 66 GyE in 10 fractions; B, 72.6 GyE in 22 fractions; and C, 77 GyE in 35 fractions) were used, depending on the tumor location. Results: Of the 266 patients, 104, 95, and 60 patients were treated with protocols A, B, and C, respectively. Seven patients with double lesions underwent two different protocols. The overall survival rates after 1, 3 and 5 years were 87%, 61%, and 48%, respectively (median survival, 4.2 years). Multivariate analysis showed that better liver function, small clinical target volume, and no prior treatment (outside the irradiated field) were associated with good survival. The local control rates after 1, 3, and 5 years were 98%, 87%, and 81%, respectively. Multivariate analysis did not identify any factors associated with good local control. Conclusions: This study showed that proton beam therapy achieved good local control for HCC using each of three treatment protocols. This suggests that selection of treatment schedules based on tumor location may be used to reduce the risk of late toxicity and maintain good treatment efficacy.

    The authors investigated the accuracy of contrast-enhanced color Doppler US in the assessment of the effectiveness of intralesional treatment of hepato carcinomas. The absence of any intralesional vascular signals in all treated patients and the possible demonstration of complete tumor necrosis seems to confirm the important role of the contrast-enhanced color Doppler US in monitoring focal hepatic lesions after intralesional treatment

    Evidence-based management of patients with hepatocellular carcinoma (HCC) is key to their optimal care. For individuals at risk for HCC, surveillance usually involves ultrasonography (there is controversy over use of biomarkers). A diagnosis of HCC is made based on findings from biopsy or imaging analyses. Molecular markers are not used in diagnosis or determination of prognosis and treatment for patients. The Barcelona Clinic Liver Cancer algorithm is the most widely used staging system. Patients with single liver tumors or as many as 3 nodules ≤3 cm are classified as having very early or early-stage cancer and benefit from resection, transplantation, or ablation. Those with a greater tumor burden, confined to the liver, and who are free of symptoms are considered to have intermediate-stage cancer and can benefit from chemoembolization if they still have preserved liver function. Those with symptoms of HCC and/or vascular invasion and/or extrahepatic cancer are considered to have advanced-stage cancer and could benefit from treatment with the kinase inhibitor sorafenib. Patients with end-stage HCC have advanced liver disease that is not suitable for transplantation and/or have intense symptoms. Studies now aim to identify molecular markers and imaging techniques that can detect patients with HCC at earlier stages and better predict their survival time and response to treatment.

    Narayan, Vivek; Haas, Naomi Balzer

    2016-01-01

    Background Axitinib is a next-generation, selective tyrosine kinase inhibitor targeting the vascular endothelial growth factor receptors. It is approved for the treatment of metastatic renal cell carcinoma (mRCC) based on a demonstrated progression-free survival advantage over sorafenib in the second-line treatment setting. However, given the variety of available targeted therapies for mRCC, appropriate patient selection for the available therapies remains a significant clinical challenge. Purpose This review summarizes the available evidence on the clinical, toxicity, and pharmacologic considerations for determining appropriate patient selection for axitinib therapy. In addition, it describes recent data on the use of predictive biomarkers to guide clinical management. This paper consists of material obtained via PubMed and Medline literature searches through October 2015. Conclusion Axitinib has a well-established role in the management of mRCC. Consistent clinical efficacy has been demonstrated across prognostic risk groups and prior therapeutic exposures. Although axitinib is generally well tolerated, appropriate toxicity management is critical to maximizing drug delivery and optimizing treatment outcomes. Although incident hypertension has been associated with improved clinical outcomes on axitinib, there are currently no validated clinical or genetic predictive biomarkers to guide patient selection.

  2. The role of radiotherapy and chemotherapy in the treatment of merkel cell carcinoma

    International Nuclear Information System (INIS)

    Purpose/Objective: To determine the role of radiation therapy and chemotherapy in the treatment of Merkel Cell Carcinoma (MCC), a highly aggressive skin tumor. Materials and Methods: A retrospective analysis of 27 patients treated at the Rabin Medical Center in Israel is presented. Data on 40 patients, including 13 additional patients from the Israel Cancer Registry, were analyzed for prognostic factors using uni- and multivariate analysis. Results: Univariate analysis revealed regional lymph node involvement and coexistence of secondary primary as unfavorable prognostic factors. In multivariate analysis only lymph node involvement showed borderline statistical significance. Radiation therapy was highly effective when given as consolidation after surgery or chemotherapy. In 11 patients irradiated prophylactically only one in-field relapse (9%) occurred. Radiation therapy yielded responses in 15 of 15 measurable sites (5CR, 10 PR). Chemotherapy produced responses in 18 of 26 treatments (70%), mostly CR (41%). However, in the absence of radiation therapy the responses were of short duration. Conclusion: Our data support combined treatment with chemotherapy followed by irradiation for advanced loco-regional disease. Further large scale investigations are warranted to confirm this approach

  3. The importance of postoperative radiation therapy in the treatment of Merkel cell carcinoma

    International Nuclear Information System (INIS)

    Purpose: To determine the role of postoperative radiation therapy in the treatment of Merkel cell carcinoma (MCC). Methods and Materials: Eighty patients with MCC of the skin were treated with curative intent at the Queensland Radium Institute between 1981 and 1991. Fifty-one patients (63.7%) were referred after initial biopsy for further treatment and 29 patients (36.3%) were referred with locally recurrent disease following primary surgery elsewhere. Thirteen patients (16.3%) presented with nodal disease without a clinically definable primary skin lesion. Results: Of the 80 patients, 38 had undergone surgery (S) alone, 34 surgery plus radiotherapy (S + RT), 7 RT after incomplete S, and 1 patient had chemotherapy (CT) plus RT. Overall survival at 36 months for all patients was 68%. All of the 38 patients treated with S alone relapsed. The median time to recurrence was 5.5 months. Ten of the 34 patients treated with S + RT relapsed. The median time to recurrence was 16.5 months. Of the 80 patients, 55 have relapsed after primary treatment, 25 have developed systemic metastases, and 26 patients have died as a direct result of MCC. Conclusion: Our large series confirms earlier reports from this Institute and highlights the importance of S + RT over S alone in preventing local recurrence of this highly malignant skin cancer

    2011-01-01

    Hepatocellular carcinoma (HCC) is among the most common cancer diseases worldwide. Arterial hypervascularisation is an essential step for HCC tumorigenesis and can be targeted by transarterial chemoembolization (TACE). This interventional method is the standard treatment for patients with intermediate stage HCC, but is also applied as "bridging" therapy for patients awaiting liver transplantation in many centers worldwide. Usually the devascularization effect induced by TACE is transient, consequently resulting in repeated cycles of TACE every 4-8 wk. Despite documented survival benefits, TACE can also induce the up-regulation of proangiogenic and growth factors, which might contribute to accelerated progression in patients with incomplete response. In 2007, sorafenib, a multi-tyrosine kinase and angiogenesis inhibitor, was approved as the first systemic treatment for advanced stage HCC. Other active targeted compounds, either inhibitors of angiogenesis and/or growth factors, are currently being investigated in numerous clinical trials. To overcome revascularisation or tumor progression under TACE treatment it seems therefore attractive to combine TACE with systemic targeted agents, which might theoretically block the effects of proangiogenic and growth factors. Over the last 12 mo, several retrospective or prospective cohort studies combining TACE and sorafenib have been published. Nevertheless, robust results of the efficacy and tolerability of such combination strategies as proven by randomized, controlled trials are awaited in the next two years.

    Full Text Available Abstract Background The aim of this treatment planning study was to investigate the potential advantages of intensity-modulated (IM proton therapy (IMPT compared with IM photon therapy (IMRT in nasopharyngeal carcinoma (NPC. Methods Eight NPC patients were chosen. The dose prescriptions in cobalt Gray equivalent (GyE for gross tumor volumes of the primary tumor (GTV-T, planning target volumes of GTV-T and metastatic (PTV-TN and elective (PTV-N lymph node stations were 72.6 GyE, 66 GyE, and 52.8 GyE, respectively. For each patient, nine coplanar fields IMRT with step-and-shoot technique and 3D spot-scanned three coplanar fields IMPT plans were prepared. Both modalities were planned in 33 fractions to be delivered with a simultaneous integrated boost technique. All plans were prepared and optimized by using the research version of the inverse treatment planning system KonRad (DKFZ, Heidelberg. Results Both treatment techniques were equal in terms of averaged mean dose to target volumes. IMPT plans significantly improved the tumor coverage and conformation (P E were more than doubled by IMRT plans. Conclusion In radiotherapy of NPC patients, three-field IMPT has greater potential than nine-field IMRT with respect to tumor coverage and reduction of the integral dose to OARs and non-specific normal tissues. The practicality of IMPT in NPC deserves further exploration when this technique becomes available on wider clinical scale.

  6. Evaluating adherence to the Dutch guideline for diagnosis, treatment and follow-up of laryngeal carcinomas

    International Nuclear Information System (INIS)

    Background and purpose: An evidence-based clinical practice guideline for laryngeal carcinomas was introduced in the Netherlands late 1999. The objective of this guideline was to ensure uniformity in the diagnosis, treatment, and follow-up. We retrospectively evaluated whether clinical practice changed according to the recommendations of this guideline and whether it succeeded in its aim. Material and methods: In five out of eight Dutch university hospitals, chart data of 459 patients treated before the guideline introduction were compared to data of 363 patients treated after the guideline introduction. Results: Patient and tumour characteristics were comparable among both groups. In general, the guideline recommendations were properly complied with. The patients treated before the guideline introduction were actually also for a large part already treated according to the guideline's recommendations. After its introduction, several changes according to the guideline were observed: increased rates of reassessment of biopsy samples taken in local hospitals, psychological screening (although still only performed in 10.5% of patients), application of accelerated radiotherapy schedules, clinical trial treatments, function-preserving treatments, and decreased rates of total laryngectomy, and annual chest X-rays during follow-up. Conclusions: Although a causal relationship cannot be established in this kind of observational studies, several positive changes were observed after the introduction of the guideline, and therefore the guideline seems to have contributed to more uniformity. The largest changes were seen for the guideline recommendations based on the highest levels of evidence

  7. Yttrium-90 microspheres for the treatment of hepatocellular carcinoma: A review

    International Nuclear Information System (INIS)

    To present a critical review of yttrium-90 (TheraSphere) for the treatment of hepatocellular carcinoma (HCC). Medical literature databases (Medline, Cochrane Library, and CANCERLIT) were searched for available literature concerning the treatment of HCC with TheraSphere. These publications were reviewed for scientific and clinical validity. Studies pertaining to the use of yttrium-90 for HCC date back to the 1960s. The results from the early animal safety studies established a radiation exposure range of 50-100 Gy to be used in human studies. Phase I dose escalation studies followed, which were instrumental in delineating radiation dosimetry and safety parameters in humans. These early studies emphasized the importance of differential arteriolar density between hypervascular HCC and surrounding liver parenchyma. Current trends in research have focused on advancing techniques to safely implement this technology as an alternative to traditional methods of treating unresectable HCC, such as external beam radiotherapy, conformal beam radiotherapy, ethanol ablation, trans-arterial chemoembolization, and radiofrequency ablation. Yttrium-90 (TheraSphere) is an outpatient treatment option for HCC. Current and future research should focus on implementing multicenter phase II and III trials comparing TheraSphere with other therapies for HCC

    Full Text Available Paraneoplastic syndromes of hepatocellular carcinoma (HCC are not uncommon. However, the prognosis is poor and follow-up and improvement of paraneoplastic syndromes with treatment have been reported rarely. We report a successful case in an aged man of a massive HCC with paraneoplastic syndrome, treated by combined intraarterial chemotherapy and hepatic resection. Paraneoplastic syndrome (erythrocytosis and hyperlipidemia was monitored throughout the treatment and erythropoietin (EPO mRNA also was analyzed in the resected liver. The hemoglobin level and serum levels of EPO and total cholesterol (T-cho decreased dramatically with treatment, along with a decrease in serum levels of α-fetoprotein and protein induced by vitamin vitamin K absence II (PIVKA-II. Semiquantitative reverse transcription polymerase chain reaction (RT-PCR revealed that the residual cancer expressed EPO RNA but the nontumor tissue did not. This was a rare case of paraneoplastic syndrome of HCC that was treated successfully. This case indicates that paraneoplastic syndrome reflected tumor progression and that serum levels of both EPO and T-cho might be used as tumor markers.

  9. Recent progress and future perspective of medical examination and treatment for bile duct carcinoma

    International Nuclear Information System (INIS)

    Explained are the progress during the past decade of medicare of bile duct carcinoma (BDC) leading to current status and the future perspective, from aspects of diagnosis, biliary drainage and treatment. The greatest progress in diagnosis is the introduction of multi-detector raw CT (MD-CT) with high time/space resolution resulting in, as well as of tumor site, the detection of extension, vascular invasion, remote metastasis, ascites and anatomical vascular running state essential for therapeutic planning. Advances in MD-CT image processing have also greatly contributed to the diagnostic progress. 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT and peroral cholangioscopy can cover the diagnostic defect of MD-CT for detecting small lymphatic metastasis and horizontal extension on superficies, respectively. Preoperative biliary drainage is common in Japan and this modality is negative in Western countries, which may be due to the difference in their surgical procedures of BDC. Endoscopic naso-biliary drainage through duodenal papilla is becoming popular because of its safety and low risk of dissemination. As for treatment, resection is a gold standard for BDC. Results are awaited of recent trials like the postoperative chemotherapy with gemcitabine, and neoadjuvant radio-chemotherapy with 45 Gy radiation+gemcitabine. A systematic scheme for current diagnosis and treatment of BDC is proposed in this paper. (T.T.)

  10. Could cryosurgery be an alternative treatment for basal cell carcinoma of the vulva?

    Full Text Available Basal cell carcinomas (BCC on the genital area account for less than 1% of all BCCs. Surgical management is indicated. Recurrence rate of vulvar BCC has been reported to be 10-20%. Mohs micrographic surgery (MMS is a superior surgical option. Other treatments include radiation and topical immuntherapy. Cryosurgery for vulvar BCC has not been reported. We present the case of a 88-year-old Hispanic woman with a vulvar ulcer that was confirmed as BCC by histopathology and treated with liquid nitrogen cryosurgery. Control biopsy was performed on day 90 was negative for BCC. No clinical evidence of recurrence was detected after one year. Although, the vulva is considered to be a high-risk site with respect to BCC and MMS is the gold standard for treatment, the delicate nature of the area may preclude complete removal by a surgical technique without compromising vital anatomical function. Liquid nitrogen cryosurgery uses the effects of extreme cold to effect deep destruction of the tumor and surrounding tissues. This is the first report of a vulvar BCC successfully treated with liquid nitrogen cryosurgery. We suggest this technique could be of benefit as an alternative treatment in cases where excisional procedures cannot be performed.

    Unlike other non-gynecologic solid tumors, such as breast cancer, lung cancer, metastasis to bone from endometrial carcinoma is rare, metastasis to extremity is extremely rare. We report a 51-year-old multiparous woman with FIGO Stage IVb Grade 2 endometrial adenocarcinoma which metastasized to left lower extremity bone. She received an amputation of left lower extremity below the knees, and a total abdominal hysterectomy and bilateral salpingo-oophorectomy, and followed by systemic chemotherapy, radiation therapy to the pelvis and progestational agent. She had a complete response to above treatments, and disease-free survival for 10 months. After recurrence, she received chemotherapy, radiotherapy and progestational agent once again. She had lived 56 months and is still alive by the time of report. Metastasis of endometrial carcinoma to extremity bone can rarely occur and should be considered when the patient with endometrial carcinoma complained of unexplained pain and swelling associated with extremity bone.

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

    International Nuclear Information System (INIS)

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

  13. Cetuximab in the treatment of metastatic mucoepidermoid carcinoma of the salivary glands: A case report and review of literature

    2008-09-01

    Full Text Available Abstract Introduction Patients with metastatic mucoepidermoid carcinoma of salivary glands have a poor outcome. The epidermal growth factor receptor protein is overexpressed in approximately 70% of mucoepidermoid carcinoma patients and may represent a therapeutic target. However, whether treatment with anti-epidermal growth factor receptor agents is effective is unclear and clinical trials are difficult due to the rarity of the disease. Here we assessed the activity of cetuximab in mucoepidermoid carcinoma on a molecular basis. Case presentation We present the case of a 40-year old Caucasian man with a mucoepidermoid carcinoma of the major salivary glands who developed distant bone and visceral metastases despite platinum-based chemotherapy. Epidermal growth factor receptor was overexpressed and fluorescence in situ hybridization analysis demonstrated a chromosome 7 polysomy. The patient was treated with the monoclonal antibody cetuximab in combination with cisplatin. After 11 doses of cetuximab, the patient developed brain metastases but evidence of response was documented at all extracranial metastatic sites. Conclusion This case report indicates that cetuximab can be active in mucoepidermoid carcinoma and may restore sensitivity to cisplatin in platinum-treated patients. Cetuximab does not cross the blood brain barrier and may select a metastatic clone to home the central nervous system while responding at other sites.

    Full Text Available Background: Inflammatory mammary carcinoma (IMC is locally aggressive, fast growing, highly malignant tumor that affects humans and dogs. Affected dogs usually are presented with generalized edema, pain, erythema, and skin ulceration in mammary glands. Surgery is not recommended and an effective treatment has not been established [1]. Calcarea carbonica derivative complex (M8 has demonstrated anticancer properties in a murine model, by improving innate immune response against tumor cells [2,3]. M8 is a complex high diluted medication comprised of a 10%-20% concentration of Calcarea carbonica, Aconitum napellus, Arsenicum album, Asa foetida, Conium maculatum, Ipecacuanha, Phosphorus, Rhus tox, Silicea, Sulphur, and Thuya occidentalis, all in decimal dilutions of Hahnemann in distilled water and submitted to vigorous shaking. Aim: Describe an association of M8 and piroxicam (Non-steroidal anti-inflammatory drug to treat a dog with IMC. Discussion: A 7 years old, mixed breed intact female dog was presented to the Federal University of Parana - Veterinary Hospital, Curitiba (HV-UFPR for mammary glands examination. The owners related inflammation of mammary glands with clinical course of approximately 10 days, which was treated for mastitis (cephalexin and metergoline without clinical improvement. Clinical examination revealed erythema, increased skin warmth, pain on palpation, and plaque involving the 4th and 5th right mammary glands. Abdominal ultrasound and serum biochemistry were unremarkable. Thoracic radiographs showed suspicious images of pulmonary metastasis. Fine needle biopsy was taken for cytologic examination. Cytological interpretation was a malignant epithelial neoplasm, probably a mammary carcinoma. Diagnosis of IMC was based on clinical signs and cytopathology. Dog was treated with oral (0.5 mL and topical M8 twice a day for 15 days, and pyroxican, 0.3mg/kg, PO, q24h. Clinical improvement was observed 7 days after starting

    Full Text Available Abstract Background Hepatocellular carcinoma is a primary malignant tumor of the liver that accounts for an important health problem worldwide. Only 10 to 15% of hepatocellular carcinoma patients are suitable candidates for treatment with curative intent, such as hepatic resection and liver transplantation. A majority of patients have locally advanced, liver restricted disease (Barcelona Clinic Liver Cancer (BCLC staging system intermediate stage. Transarterial loco regional treatment modalities offer palliative treatment options for these patients; transarterial chemoembolization (TACE is the current standard treatment. During TACE, a catheter is advanced into the branches of the hepatic artery supplying the tumor, and a combination of embolic material and chemotherapeutics is delivered through the catheter directly into the tumor. Yttrium-90 radioembolization (90Y-RE involves the transarterial administration of minimally embolic microspheres loaded with Yttrium-90, a β-emitting isotope, delivering selective internal radiation to the tumor. 90Y-RE is increasingly used in clinical practice for treatment of intermediate stage hepatocellular carcinoma, but its efficacy has never been prospectively compared to that of the standard treatment (TACE. In this study, we describe the protocol of a multicenter randomized controlled trial aimed at comparing the effectiveness of TACE and 90Y-RE for treatment of patients with unresectable (BCLC intermediate stage hepatocellular carcinoma. Methods/design In this pragmatic randomized controlled trial, 140 patients with unresectable (BCLC intermediate stage hepatocellular carcinoma, with Eastern Cooperative Oncology Group performance status 0 to 1 and Child-Pugh A to B will be randomly assigned to either 90Y-RE or TACE with drug eluting beads. Patients assigned to 90Y-RE will first receive a diagnostic angiography, followed by the actual transarterial treatment, which can be divided into two sessions in case

    Full Text Available Background: Cervical cancer remains the most common cancer among women in this part of the world. Bangladesh has the highest level of incidence and mortality rates due to cervical cancer among women. Cervical cancer is a preventable disease by screening and treatment of pre-invasive condition. Unfortunately, there is no effective screening program in Bangladesh.Objective: The objective was to analyze the clinico-pathologic characteristics and, subsequently the therapy delivered to the patients.Materials and method: This cross sectional study was done from January to December 2011 in oncology division of Delta Medical College and Hospital, Dhaka, Bangladesh. During this period a total of 2264 female carcinoma patients were registered. Out of them 523 patients were with the diagnosis of carcinoma of cervix. Evaluation and characterization of patients with carcinoma cervix were done according to the age group, clinical stages and surgical status. External beam radiotherapy (EBRT and doses, brachytherapy doses and fractions, time interval between EBRT and brachytherapy, neo-adjuvant and concurrent chemotherapy status were the factors taken into consideration for the analysis of treatment of these patients.Results: The study revealed that the incidence of carcinoma cervix was 23% and highest incidence was between 40-50 years of age group, most of the patients were in Stage IIB (34% and IIIB (28% and 31% with unknown stage. About 44% patients were referred postoperatively and most of them with unknown stage. Almost 90% patients received EBRT, 24% patients received concurrent chemo-radiation, 46% of them completed 5 cycles of concurrent chemotherapy and 8.6% patients received neo-adjuvant chemotherapy. About 69% patients received brachytherapy with HDR Co-60 sources and 23% of patients received their brachytherapy treatment after 12 weeks of completion of EBRT.Conclusion: Lack of proper clinical evaluation and documentation, delay in referral and lack

  18. Rationalization and regionalization of treatment for ductal carcinoma in situ of the breast

    International Nuclear Information System (INIS)

    Purpose: In ductal carcinoma in situ (DCIS) of the breast, conservative surgery plus radiotherapy (CS+RT) decreases risk of recurrence compared with CS alone. Although nearly one third of patients are reported as treated with CS alone, it is unclear whether this potentially 'undertreated' group represents high- or low-risk patients. We evaluated national patterns of DCIS treatment from 1996 to 2001 by patient risk profile. Methods and Materials: In a retrospective cohort of DCIS patients from the Surveillance, Epidemiology, and End Results data, patients were risk stratified on the basis of age at diagnosis, tumor grade, tumor size, and comedo histology. Treatment included CS alone, CS+RT, or mastectomy. Patients were followed for the development of ipsilateral invasive or in situ event. Results: Of 14,202 patients, 19% were low-risk, 46% moderate-risk, and 35% high-risk. A total of 28% received CS alone, 40% CS+RT, and 31% mastectomy. Overall, only 17% of high-risk patients but 44% of low-risk patients received CS alone (p < 0.001). In multivariable analysis, older age, smaller tumor size, and treatment in San Francisco/Los Angeles predicted treatment with CS alone (p < 0.01). Yet despite the tendency to receive CS alone, patients in San Francisco/Los Angeles did not experience an increased risk of ipsilateral event (hazard ratio = 0.79; 95% confidence interval, 0.55-1.12). Conclusion: Patient risk profiles rationally affect treatment choice in DCIS patients, and the vast majority of high-risk patients do not receive CS alone. Additional follow up is needed to determine whether geographic variation in care influences long-term outcomes

  19. Nephron sparing surgery as the treatment of choice in renal cell carcinoma

    International Nuclear Information System (INIS)

    Advances in imaging diagnostics have contributed to the frequent detection of small kidney tumours both at an early stage and of low grade. Although radical nephrectomy is still the gold standard in Renal Cell Carcinoma (RCC) treatment, yet it slowly ceases to be the standard approach and open or laparoscopic Nephron Sparing Surgery (NSS) is becoming more and more common. Ai m. The purpose of the study was to determine the functional and oncological outcomes of NSS for RCC basing on an analysis of 108 patients. Material and methods. The patients were divided into two groups: T1a (≤ 4 cm) and T1b (≥ 4 ≤ 7 cm). We performed an analysis of all patients with a minimal follow-up time of 24 months. In the majority of patients the diagnosis was clear cell carcinoma(83.9%). Results. G2 tumours were the most common (51.7%). The cumulative proportion of survivors without local relapse within the operated kidney and/or in the local lymph nodes and without distant metastases after 2 and 3 years was 99% and 93%, respectively. Our results support the fact that in pT1a and pT1b patients NSS is a safe and effective procedure. The size of pT1 tumours has no bearing on 2-year and 3-year recurrence-free survivals. Conclusion. Intraoperative ultrasound allows for further identification of additional neo plasmatic foci and for the use of the best surgical approach. Intraoperative ultrasound is useful in NSS, and especially in those cases, where the tumor lies in the central part of the kidney. (authors)

Clinical presentation is characterized by advanced stage at diagnosis and rapidly progressive disease. In daily clinical practice ...

  1. Radiation therapy for epidermoid carcinoma of the anal canal, clinical and treatment factors associated with outcome

    International Nuclear Information System (INIS)

    Background and purpose: In recent years, treatment with combined chemotherapy and radiation has become the standard of care for epidermoid carcinoma of the anus. However, optimal radiotherapy techniques and doses are not well established. Materials and methods: During the period 1975-1997, 106 patients with epidermoid carcinoma of the anal canal underwent radiation therapy. Treatment policies evolved from radiation therapy alone or with surgery, to combined chemotherapy and radiation followed by surgery, to combined chemotherapy and radiation. Results: Overall 74% of patients were NED (no evidence of disease) at last follow-up. The most important clinical correlate with ultimate freedom from disease (includes the contribution of salvage surgery) was extent of disease. The 5-year ultimate freedom from disease was 87±5% for T1/T2N0, 78±10% for T3N0 (15% salvaged by surgery), and 43±10% for either T4N0 or any N+ lesions (P<0.001, Tarone-Ware). There was no difference between planned vs. expectant surgery (5-year ultimate NED: 67±11% planned surgery vs. 73±5% expectant surgery). The most important correlate with late toxicity was a history of major pelvic surgery (surgical vs. non-surgical group: P=0.013, Fisher's exact test, two-tailed summation). Thirty-three additional malignancies have been seen in 26 patients. The most common additional malignancies were gynecologic (nine cases), head and neck (six cases), and lung cancer (five cases). Conclusions: For T1/T2N0 disease, moderate doses of radiation combined with chemotherapy provided adequate treatment. T4N0 and N+ lesions are the most appropriate candidates for investigational protocols evaluating dose intensification. T3N0 tumors may also be appropriate for investigation; however, dose intensification may ultimately prove counterproductive if the cure rate is not improved and salvage surgery is rendered more difficult. The volume of irradiated small bowel should be minimized for patients who have a past

    Topical application of anticancer drugs for the treatment of malignancies represents a new challenge in dermatology, potentially being an alternative therapeutic approach for the efficacious treatment of non-melanoma skin cancer, that is, actinic keratoses, and malignant lesions of the skin caused by ultraviolet radiation. Anti-proliferative and antimitotic drugs, including many of the taxanes, are currently under investigation for the treatment of cutaneous malignant transformation of actinic keratoses, particularly the squamous cell carcinoma. Paclitaxel-loaded ethosomes® are proposed as topical drug delivery systems for the treatment of this pathology due to their suitable physicochemical characteristics and enhanced skin penetration ability for deep dermal delivery. Our in vitro data show that the skin application of paclitaxel-loaded ethosomes® improved the permeation of paclitaxel in a stratum corneum-epidermis membrane model and increased its anti-proliferative activity in a squamous cell carcinoma model as compared to the free drug. The results obtained encouraged the use of the paclitaxel-loaded ethosomes® as the formulation for the potential treatment of squamous cell carcinoma, a malignant transformation of actinic keratoses.

  3. Sunitinib treatment for patients with clear-cell metastatic renal cell carcinoma: clinical outcomes and plasma angiogenesis markers

    International Nuclear Information System (INIS)

    Sunitinib is a protein tyrosine kinase-inhibitor targeting VEGFR, c-kit and PDGFR. It has been approved for the treatment of metastatic renal-cell carcinoma and gastrointestinal stromal tumors. Although it has been shown to prolong disease-free and overall survival in renal-cell carcinoma patients, only 70% of the treated population receive a clinical benefit (CB) from the treatment. Markers that could predict clinical benefit to sunitinib would be an important aid in monitoring and following their treatment. We assessed the outcome and plasma proangiogenic factors in patients with metastatic renal cell carcinoma (mRCC) treated with sunitinib in our institution. We have treated 42 patients with metastatic clear-cell renal carcinoma with sunitinib. Plasma concentrations of VEGF-A, sVEGFR2 and PDGF were determined by ELISA. At the time of analysis 39 patients were evaluable for response and 30 patients had obtained a clinical benefit (CB). Median progression-free survival was 268 days (8.93 months) and median overall survival was 487 days (16.23 months). Interestingly, disease stabilization or objective response resulted in comparable overall survival. Most treatment-related adverse events were of mild-to-moderate intensity with one treatment-related death. Plasma sVEGFR2 and PDGF levels had no predictive value. Fold-increase in plasma VEGF was significantly lower in patients that obtained a CB as compared to patients that progressed after two cycles of treatment. Plasma VEGF did not increase in patients with initial CB at the time of progression. Sunitinib showed substantial activity in mRCC. Disease stabilization or objective response resulted in comparable overall survival and both outcomes should be considered positive. Fold-increase in plasma VEGF predicts for CB and could be a candidate marker. Progression after initial CB is not associated with elevated plasma VEGF, implying a different mechanism of resistance

    The aim of the study was to assess the efficacy and toxicity of cetuximab in the combined treatment for patients with recurrent and/or metastatic nasopharyngeal carcinoma (R/M NPC). Between March 2007 and November 2011, a total of 30 R/M NPC patients treated with comprehensive therapy including cetuximab were retrospectively enrolled. Intensity-modulated radiation therapy was delivered in recurrent disease with a median dose of 60 Gy. Chemotherapy regimens included TP/TPF (docetaxel 60-75 mg/m d1+DDP 25 mg/m d1-3±5-FU 500 mg/m/day with 120-h infusion), GP (gemcitabine 1.0 g/m d1, d8+DDP 25 mg/m d1-3), and PC (paclitaxel 60 mg/m/week d1+carboplatin AUC 2/week d1). Acute and late toxicities were documented by the radiation oncologists. The median age of the patients was 44 years (range 26-62). A total of 21 patients (70%) achieved response (CR+PR). The median survival time, time to progression, and 2-year overall survival were 23.6, 12.2 months, and 53.3%, respectively. Cetuximab appears to be effective and well tolerated when combined with chemoradiation therapy for the treatment of R/M NPC. PMID:26352217

    Merkel cell carcinoma (MCC) is a rare tumour of the skin of neuro-endocrine origin probably developing from neuronal mechanoreceptors. A collaborative group of multidisciplinary experts form the European Dermatology Forum (EDF), The European Association of Dermato-Oncology (EADO) and the European Organization of Research and Treatment of Cancer (EORTC) was formed to make recommendations on MCC diagnosis and management, based on a critical review of the literature, existing guidelines and expert's experience. Clinical features of the cutaneous/subcutaneous nodules hardly contribute to the diagnosis of MCC. The diagnosis is made by histopathology, and an incisional or excisional biopsy is mandatory. Immunohistochemical staining contributes to clarification of the diagnosis. Initial work-up comprises ultrasound of the loco-regional lymph nodes and total body scanning examinations. The primary tumour should be excised with 1-2cm margins. In patients without clinical evidence of regional lymph node involvement, sentinel node biopsy is recommended, if possible, and will be taken into account in a new version of the AJCC classification. In patients with regional lymph node involvement radical lymphadenectomy is recommended. Adjuvant radiotherapy might be considered in patients with multiple affected lymph nodes of extracapsular extension. In unresectable metastatic MCC mono- or poly-chemotherapy achieve high remission rates. However, responses are usually short lived. Treatment within clinical trials is regarded as a standard of care in disseminated MCC. PMID:26257075

    2013-01-01

    Full Text Available Incidence of basal cell carcinoma (BCC, the most common skin cancer in humans, is rising. Surgery is the mainstay of treatment but there is no standard of care for locally advanced or metastatic disease. Hedgehog signaling proteins are critical for cell growth and differentiation during embryogenesis; Hh pathway is silenced in adults. Dysregulated or aberrant Hh signaling has been implicated in the pathogenesis of BCC. This hyperactive pathway can be inhibited by use of smoothened inhibitors such as vismodegib. Food and drug administration approved this oral, once-daily medication in 2012 to treat adults with metastatic BCC or locally advanced, recurrent BCC after surgery and also for patients with locally advanced BCC who are not candidates for surgery or radiation treatment. Clinical studies have shown it to be highly efficacious and the most common adverse effects include, muscle spasms, alopecia and dysgeusia. Use of targeted biologic modifiers, exemplified by Hh directed therapeutics offer a new hope to patients with high-surgical morbidity or inoperable tumors.

    Hepatocellular carcinoma (HCC) is the sixth most common cancer in the world. The majority of patients with HCC present with unresectable disease. These patients have historically had limited treatment options secondary to HCC demonstrating chemoresistance to the currently available systemic therapies. Additionally, normal liver parenchyma has shown intolerance to tumoricidal radiation doses, limiting the use of external beam radiation. Because of these limitations, novel percutaneous liver-directed therapies have emerged. The targeted infusion of radioactive microspheres (radioembolization) represents one such therapy. Radioembolization is a minimally invasive transcatheter therapy through which radioactive microspheres are infused into the hepatic arteries that supply tumor. Once infused, these microspheres traverse the hepatic vascular plexus and selectively implant within the tumor arterioles. Embedded within the arterioles, the 90Y impregnated microspheres emit high energy and low penetrating radiation doses selectively to the tumor. Radioembolization has recently shown promise for the treatment of patients with unresectable HCC. The objective of this review article is to highlight twocurrently available radioembolic devices (90Y, 188Rh) and provide the reader with a recent review of the literature.

    The last decades have known continuous development of therapeutic strategies in hepatocellular carcinoma (HCC). Unfortunately the disease it still not diagnosed until it is already at an intermediate or even an advanced disease. In these circumstances transarterial chemoembolization (TACE) is considered an effective treatment for HCC. The most important independent prognostic factor of both disease free survival and overall survival is the presence of complete necrosis. Therefore, treatment outcomes are dictated by the proper use of radiological imaging. Current guidelines recommend contrast enhanced computer tomography (CECT) as the standard imaging technique for evaluating the therapeutic response in patients with HCC after TACE. One of the most important disadvantage of CECT is the overestimation of tumor response. As an attempt to overcome this limitation contrast enhanced ultrasound (CEUS) has gained particular attention as an imaging modality in HCC patients after TACE. Of all available imaging modalities, CEUS performs better in the early and very early assessment of TACE especially after lipiodol TACE. As any other imaging techniques CEUS has disadvantages especially in hypovascular tumors or in cases of tumor multiplicity. Not far from now the current limitations of CEUS will be overcome by the new CEUS techniques that are already tested in clinical practice such as dynamic CEUS with quantification, three-dimensional CEUS or fusion techniques.

  10. FDG-PET/CT imaging for staging and radiotherapy treatment planning of head and neck carcinoma

    International Nuclear Information System (INIS)

    Positron emission tomography (PET) has a potential improvement for staging and radiation treatment planning of various tumor sites. We analyzed the use of 18F-fluorodeoxyglucose (FDG)-PET/computed tomography (CT) images for staging and target volume delineation of patients with head and neck carcinoma candidates for radiotherapy. Twenty-two patients candidates for primary radiotherapy, who did not receive any curative surgery, underwent both CT and PET/CT simulation. Gross Tumor Volume (GTV) was contoured on CT (CT-GTV), PET (PET-GTV), and PET/CT images (PET/CT-GTV). The resulting volumes were analyzed and compared. Based on PET/CT, changes in TNM categories and clinical stage occurred in 5/22 cases (22%). The difference between CT-GTV and PET-GTV was not statistically significant (p = 0.2) whereas the difference between the composite volume (PET/CT-GTV) and CT-GTV was statistically significant (p < 0.0001). PET/CT fusion images could have a potential impact on both tumor staging and treatment planning

  11. Fractionation study on 3F/wk or 5F/wk treatment of oral carcinoma

    International Nuclear Information System (INIS)

    Though significant advances have been made in the past 5 years in radiobiology, it has not been possible to reach the perfect mode of treatment policy. In the present series 90 patients of oral carcinoma were treated by two fracionation regimes 3F/wk and 5F/wk, on a random basis. It was observed that there was no appreciable difference in tumour response in both groups. The record of Hb percent fall and the fall during therapy was comparable in both groups. Acute skin reactions occurred more in 3F/wk group but they did not cross grade 3(WHO grading) and were by no means. prohibitive. Chronic skin reaction was observed to be commonest in the form of pigmentation and occurred in both groups with no statistical differences. Acute and chronic mucus membrane reactions occurred with equal intensity in both arms of the trial and both were markedly dependent on oral hygiene. The follow-up study revealed no major differences in both groups. It was notable that 5F/wk group had more defaulters. The authors' interim conclusion is that there are no contraindications to the clinical application of 3F/wk treatment regime. This is supported by statistical evaluation. (author)

  12. In vivo dose verification for photon treatments of head and neck carcinomas using MOSFET dosimeters

    International Nuclear Information System (INIS)

    In vivo dosimetry was performed for the head and neck carcinoma patients during the treatment of a large photon field using MOSFETs. This study followed the protocols recommended by the European Society for Therapeutic Radiology and Oncology. A total of 32 portals belonging to 12 patients were under investigation. Results showed that the deviation between in vivo midline doses and planned target doses was partly due to the manual dose calculations in the treatment planning which used the patient geometric thickness rather than the radiological thickness. Other factors responsible for this deviation included the difficult positioning of MOSFETs on the face mask, the asymmetric positioning of MOSFETs on the left and right sides of the mask, and the asymmetric tissue inhomogeneities with respect to the body midline. To reduce the deviation contributed from these factors, in vivo midline doses were calculated by averaging the results for each bilaterally opposed portals and compared with corresponding planned target doses. This comparison showed that MOSFET dosimeters are suitable for in vivo dosimetry of the present study

  13. Study of the diagnosis and treatment of renal cell carcinoma using monoclonal antibodies

    International Nuclear Information System (INIS)

    Among the potential applications of monoclonal antibodies (Mabs) in the diagnosis and treatment of human cancer is the use in the specific detection of cancer sites and the selective destruction of cancer cells. Fetal kidney was used as an immunogen to develop Mab A6H, which is highly reactive to 16/16 renal cell carcinoma (RCC) cell lines and to 16/19 human RCC specimens. RCC xenografts as small as 40 mg have been imaged clearly in radioimmunoscintigraphy studies using A6H labeled with iodine-131. In Mab-targeted radiotherapy studies, 2 doses of 100-150 uCi 131I-labeled A6H or an 131 I-labeled A6H-C5H cocktail caused tumor regression or tumor growth arrest in >80% of treated mice, while no such effect was observed in mice treated with 131I-labeled control Mab or unlabeled A6H. Internal radiation dosimetry, which was calculated by computer analysis of sequential radioimmunoscintigraphy, showed that A6H delivered approximately 35 rad/uCi of the injected dose to RCC xenografts. When the radiation dose to the tumor was 3000 rad resulted in tumor regression or growth arrest in >85% of mice. A clinical trial using 131I-labeled A6H in the diagnosis and treatment of RCC is now underway at our institution

  14. Meta-analysis of rates of erectile function after treatment of localized prostate carcinoma

    International Nuclear Information System (INIS)

    Purpose: The results of a 1997 meta-analysis of the rates of erectile function after external beam radiotherapy (EBRT) and radical prostatectomy have been widely used in patient and professional education materials and as a reference against which new findings are compared. With a number of recent publications, it is now possible to update this analysis and compare brachytherapy with or without EBRT with EBRT alone, standard and nerve-sparing radical prostatectomy, and cryotherapy. Methods: A comprehensive literature review and subsequent meta-analysis of the rates of erectile dysfunction associated with the treatments of localized prostate carcinoma was conducted. A simple logistic regression analysis was used to combine the data from the 54 articles that met the selection criteria. Results: The predicted probability of maintaining erectile function after brachytherapy was 0.76, after brachytherapy plus EBRT 0.60, after EBRT 0.55, after nerve-sparing radical prostatectomy 0.34, after standard radical prostatectomy 0.25, and after cryotherapy 0.13. When only studies reporting ≥2 years follow-up were considered, the only significant change was a decline in the probability for nerve-sparing radical prostatectomy. No brachytherapy studies had a follow-up of ≥2 years. When the probabilities were adjusted for age, the spread between the RT methods and surgical approaches was greater. Conclusion: The differences in the probability of maintaining erectile function after different treatments of localized prostate cancer are significant

    OBJECTIVE To study the diagnosis and treatment of chromophobe cell renal carcinoma (CCRC). METHODS Three cases of CCRC were studied by analyzing the results of an operation, by light microscopy, immunohistochemistry, Hale's colloidal iron staining and electronmicroscopy (EMC). RFESULTS Doppler ultrasonic and CT features were not specific. Histopathology: Grossly the tumor tissue was homogeneous, light brown in color with central necrotic foci; Light microscopy: Macrocyte, fine reticular cytoplasm with clear cell border; Hale's colloidal iron staining: positive; positive EMA, CK19, vimentin, Ckpan, and negative S-100; EMC: numerous intracyto-plasmic membranous small cysts. All patients were followed up for 14.1-31 months (19.7 months on average), one patient had lung metastasis 11 months after resection of a G,~ tumor, two alive patients had no local recurrences and metastases. CONCLUSIONS CCRC is histo-pathologically, immunohistochemically and electron microscopically distinct from other renal cancers. Surgical tumor removal is the best way for treatment. It is probably a type of cancer with low malignant potential and favorable prognosis.

    Full Text Available Basal cell carcinoma (BCC is the most common cancer in individuals with fair skin type (I–II and steadily increasing in incidence (70% of skin malignancy. It is locally invasive but metastasis is usually very rare, with an estimated incidence of 0.0028%–0.55%. Conventional therapy is surgery, especially for the H region of the face and infiltrative lesions; in case of inoperable tumors, radiotherapy is a valid option. Recently, topical photodynamic therapy (PDT has become an effective treatment in the management of superficial and small nodular BCC. PDT is a minimally invasive procedure that involves the administration of a photo-sensibilizing agent followed by irradiation at a pre-defined wavelength; this determines the creation of reactive oxygen species that specifically destroy target cells. The only major side effect is pain, reported by some patients during the irradiation. The high cure rate and excellent cosmetic outcome requires considering this possibility for the management of patients with both sporadic and hereditary BCC. In this article, an extensive review of the recent literature was made, in order to clarify the role of PDT as a possible alternative therapeutic option in the treatment of BCC.

    A study was made of adrenocortical hormone production under electroacupuncture stimulation of the Tsu-San-Li locus in rabbits with a lesion in the fornix, stria terminalis, ventromedial nucleus or arcuate nucleus. In rabbits with a lesion in the stria terminalis or ventromedial nucleus, electroacupuncture stimulation of Tsu-San-Li resulted in no increase in phase 1 but an increase in phase 2 of adrenocortical hormone production. In rabbits with a lesion in the fornix or arcuate nucleus electroacupuncture stimulation of Tsu-San-Li was followed by increased adrenocortical hormone production in the both phases. These results show that the stria terminalis and the ventromedial nucleus play a major role in the augmentation of adrenocortical hormone production by electroacupuncture stimulation of Tsu-San-Li.

    To evaluate the safety and efficacy of transcatheter arterial chemoembolization (TACE) followed by radiotherapy (RT) in treatment-naive patients with locally advanced hepatocellular carcinoma (HCC). Eligibility criteria were as follows: newly diagnosed with HCC, the Barcelona Clinic Liver Cancer stage C, Child-Pugh class A or B, and no prior treatment for HCC. Patients with extrahepatic spread were excluded. A total of 59 patients were retrospectively enrolled. All patients were treated with TACE followed by RT. The time interval between TACE and RT was 2 weeks as per protocol. A median RT dose was 47.25 Gy10 as the biologically effective dose using the α/β = 10 (range, 39 to 65.25 Gy10). At 1 month, complete response was obtained in 3 patients (5%), partial response in 27 patients (46%), stable disease in 13 patients (22%), and progressive disease in 16 patients (27%). The actuarial one- and two-year OS rates were 60.1% and 47.2%, respectively. The median OS was 17 months (95% confidence interval, 5.6 to 28.4 months). The median time to progression was 4 months (range, 1 to 35 months). Grade 3 or greater liver enzyme elevation occurred in only two patients (3%) after RT. Grade 3 gastroduodenal toxicity developed in two patients (3%). The combination treatment of TACE followed by RT with two-week interval was safe and it showed favorable outcomes in treatment-naive patients with locally advanced HCC. A prospective randomized trial is needed to validate these results.

  20. The Treatment Responses in Cases of Radiation Therapy to Portal Vein Thrombosis in Advanced Hepatocellular Carcinoma

    International Nuclear Information System (INIS)

    Purpose: To review the response to radiation therapy for hepatocellular carcinoma (HCC) with portal vein thrombosis (PVT) and determine the factors favoring its efficacy. Methods and Materials: Patients with HCC and PVT referred for radiation therapy between 1997 and 2005 were retrospectively reviewed. Patients who had undergone treatment to primary HCC before radiation or had extrahepatic metastasis were excluded. A radiation dose of 60 Gy with 2 to 3Gy per fraction was prescribed. Clinical features before therapy were investigated, and the most significant imaging change after radiotherapy was regarded as the treatment response. Survival times were compared and the hazard ratios of independent variables were determined. Results: The treatment response rate of the 326 patients included in the study was 25.2% (n = 82). The median survival times were 13.3, 11.6, 9.0, 4.5, and 2.1 months for complete response, partial response, vascular transformation, no response, and the lost follow-up patients, respectively. Statistically significant differences in survival were not found among responder groups (p = 0.224-0.916) but were found between responders and nonresponders (p = 0.002). The most significant independent variables associated with survival (p < 0.001) were performance status and radiation dose. Minor independent factors were ascites, alfa-fetoprotein, albumin, and HBsAg (p = 0.009-0.038). In patients with favorable performance status, those with no more than one minor risk factor had a superior prognosis after radiation therapy (p = 0.013). This result was verified by a review of similar patients in 2006. Conclusion: Radiation therapy is the treatment of choice for selected HCC patients with PVT

  1. Salvage Treatment With Hypofractionated Radiotherapy in Patients With Recurrent Small Hepatocellular Carcinoma

    International Nuclear Information System (INIS)

    Purpose: To investigate the rates of tumor response and local control in patients with recurrent small hepatocellular carcinoma (HCC) treated with hypofractionated radiotherapy (RT) as a salvage treatment and to evaluate treatment-related toxicities. Methods and Materials: Between 2006 and 2009, a total of 20 patients with recurrent small HCC were treated with hypofractionated RT after the failure of previous treatment. The eligibility criteria for hypofractionated RT were as follows: 1) HCC less than 5 cm, 2) HCC not adjacent to critical organs, 3) HCC without portal vein tumor thrombosis, and 4) less than 15% of normal liver volume that would be irradiated with 50% of prescribed dose. The RT dose was 50 Gy in 10 fractions. The tumor response was determined by CT scans performed 3 months after the end of RT. Results: The median follow-up period after RT was 22 months. The overall survival rates at 1 and 2 years were 100% and 87.9%, respectively. Complete response (CR) was achieved in seven of 20 lesions (35%) evaluated by CT scans performed 3 months after the end of RT. In-field local control was achieved in 85% of patients. Fourteen patients (70%) developed intra-hepatic metastases. Six patients developed grade 1 nausea or anorexia during RT, and two patients had progression of ascites after RT. There was no grade 3 or greater treatment-related toxicities. Conclusions: The current study showed a favorable outcome with respect to hypofractionated RT for small HCC. Partial liver irradiation with 50 Gy in 10 fractions is considered tolerable without severe complications.

  2. Transcatheter Treatment of Hepatocellular Carcinoma with Doxorubicin-loaded DC Bead (DEBDOX): Technical Recommendations

    International Nuclear Information System (INIS)

    Tranarterial chemoembolization (TACE) has been established by a meta-analysis of randomized controlled trials as the standard of care for nonsurgical patients with large or multinodular noninvasive hepatocellular carcinoma (HCC) isolated to the liver and with preserved liver function. Although conventional TACE with administration of an anticancer-in-oil emulsion followed by embolic agents has been the most popular technique, the introduction of embolic drug-eluting beads has provided an alternative to lipiodol-based regimens. Experimental studies have shown that TACE with drug-eluting beads has a safe pharmacokinetic profile and results in effective tumor killing in animal models. Early clinical experiences have confirmed that drug-eluting beads provide a combined ischemic and cytotoxic effect locally with low systemic toxic exposure. Recently, the clinical value of a TACE protocol performed by using the embolic microsphere DC Bead loaded with doxorubicin (DEBDOX; drug-eluting bead doxorubicin) has been shown by randomized controlled trials. An important limitation of conventional TACE has been the inconsistency in the technique and the treatment schedules. This limitation has hampered the acceptance of TACE as a standard oncology treatment. Doxorubicin-loaded DC Bead provides levels of consistency and repeatability not available with conventional TACE and offers the opportunity to implement a standardized approach to HCC treatment. With this in mind, a panel of physicians took part in a consensus meeting held during the European Conference on Interventional Oncology in Florence, Italy, to develop a set of technical recommendations for the use of DEBDOX in HCC treatment. The conclusions of the expert panel are summarized.

    AIM: To evaluate the efficacy of different treatment strategies for hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) and investigate factors influencing prognosis.METHODS: One hundred and seventy-nine HCC patients with macroscopic PVTT were enrolled in this study. They were divided into four groups and underwent different treatments: conservative treatment group (n = 18),chemotherapy group (n = 53), surgical resection group (n = 24) and surgical resection with postoperative chemotherapy group (n = 84). Survival rates of the patients were analyzed by the Kaplan-Meier method. A log-rank analysis was performed to identify group differences. Cox's proportional hazards model was used to analyze variables associated with survival.RESULTS: The mean survival periods of the patients in four groups were 3.6, 7.3, 10.1, and 15.1 mo respectively.There were significant differences in the survival rates among the groups. The survival rates at 0.5-, 1-, 2-, and 3-year in surgical resection with postoperative chemotherapy group were 55.8%, 39.3%, 30.4%, and 15.6% respectively, which were significantly higher than those of other groups (P<0.001). Multivariate analysis revealed that the strategy of treatment (P<0.001) and the number of chemotherapy cycles (P = 0.012) were independent survival predictors for patients with HCC and PVTT.CONCLUSION: Surgical resection of HCC and PVTT combined with postoperative chemotherapy or chemoembolization is the most effective therapeutic strategy for the patients who can tolerate operation.Multiple chemotherapeutic courses should be given postoperatively to the patients with good hepatic function reserve.

    BACKGROUND In many centers, 18F-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) is used to monitor treatment response after definitive (chemo)radiotherapy [(C)RT] for head and neck squamous cell carcinoma (HNSCC), but its usefulness remains somewhat controversial. We aimed at assessing the accuracy of FDG-PET/CT in detecting residual disease after (C)RT. METHOD All HNSCC patients with FDG-PET/CT performed to assess treatment response 10–18 weeks after definitive (C)RT at our institution during 2008–2010 were included. The patient charts were reviewed for FDG-PET/CT findings, histopathologic findings, and follow-up data. The median follow-up time for FDG-PET/CT negative patients was 26 months. RESULTS Eighty-eight eligible patients were identified. The stage distribution was as follows: I, n = 1; II, n = 15; III, n = 17; IV, n = 55. The negative predictive value, positive predictive value, specificity, sensitivity, and accuracy of FDG-PET/CT in detecting residual disease were 87%, 81%, 94%, 65%, and 85%, respectively. The corresponding specific figures for the primary tumor site were 91%, 71%, 94%, 59%, and 86% and for the neck 93%, 100%, 100%, 75%, and 94%, respectively. CONCLUSIONS In patients who have received definitive (C)RT for HNSCC, post-treatment FDG-PET/CT has good potential to guide clinical decision-making. Patients with negative scan can safely be followed up clinically only, while positive scan necessitates tissue biopsies or a neck dissection to rule out residual disease. PMID:25210484

    To describe the clinical characteristics, treatment patterns and outcomes in advanced small cell bladder cancer (aSCBC) patients and compare to those with urothelial carcinoma (UC). Individuals in the National Cancer Data Base with a diagnosis of either nodal (TxN+M0) or distant metastatic (TxNxM1) disease were identified from 1998 to 2010. We assessed the relationships between stage, treatment modalities and survival in the aSCBC cohort and compared these to UC patients. In the 960 patient aSCBC cohort (62% M1), 50% received palliative therapy alone, 68% in M1 versus 21% in M0 groups (P carcinoma patients (n = 27,796, 45% M1) lived longer compared to aSCBC patients in the N+M0 group (17.3 months vs. 13.0 months, P = 0.0007). There were not clinically significant differences in OS between UC and aSCBC patients in the M1 group. Advanced SCBC is a rare disease with a poor survival and palliative therapy is common, especially in M1 patients. In comparison to UC, the outcomes for aSCBC patients are worse in those with lymph node only involvement but similar in those with distant disease. PMID:26679712

    Purpose: To analyze whether serum squamous cell carcinoma (SCC) antigen and cytokeratin-19 fragments (CYFRA) levels can assist in selecting patients with locally advanced cervical cancer who will benefit from combined treatment or additive surgery. Methods and Materials: Of 114 patients with cervical cancer Stage IB-IV, the first 39 patients received radiotherapy, the following 75 patients received identical radiotherapy plus concomitant chemotherapy (3 cycles of carboplatin and 5-fluorouracil). SCC antigen and CYFRA 21-1 serum levels were measured before treatment, after therapy, and during follow-up. Baseline tumor markers were related to tumor stage and size and clinical outcome. Results: Before treatment, SCC antigen was elevated (>1.9 μg/L) in 60% and CYFRA 21-1 (>2.2 μg/L) in 46% of patients. For all patients, disease-free survival (DFS) was better after combined treatment (67% vs. 43%, p<0.0005). For patients with elevated baseline SCC antigen, DFS was better after combination therapy (67% vs. 27%, p=0.001) which resulted more frequently in a normal SCC antigen (93% vs. 65%, p=0.004). In contrast, in those with a normal baseline CYFRA 21-1, combined therapy resulted in a better DFS (p=0.04). Patients who achieved a normal SCC antigen or CYFRA 21-1 after treatment had a better DFS (respectively 63 vs. 17% and 64 vs. 30%). Elevated SCC antigen posttreatment indicated residual tumor in 11/12 patients (92%), elevated CYFRA 21-1 in 7/10 patients (70%). Forty-seven patients had a tumor recurrence. At recurrence, SCC antigen was raised in 70% and CYFRA 21-1 in 69%. Conclusions: In patients with an elevated pretreatment SCC antigen, SCC antigen normalized more frequently with combined treatment and those patients had a better DFS. Elevated SCC antigen or CYFRA 21-1 levels after treatment completion indicated residual tumor in respectively 92% and 70%. The presence of elevated posttreatment levels of SCC antigen or CYFRA 21-1 indicates the need for additional

    Highlights: •Although a patient with a ruptured HCC is generally considered to have a poor prognosis and treated as T4 in the 7th edition of the AJCC/UICC, some ruptured cases show a good clinical course. •There are no clear criteria established for treating a ruptured hepatocellular carcinoma (HCC) which is classified as T4 in TNM stage of UICC 7th. •This article describes that better prognosis can be expected with curative treatment in patients with a ruptured HCC, especially those with a single tumor, and without decompensated liver cirrhosis and PVTT/extrahepatic metastasis. T4 classification should not include all types of ruptured HCC. -- Abstract: Background: There are no clear criteria established for treating a ruptured hepatocellular carcinoma (HCC). To elucidate the clinical features of affected patients, we examined prognosis and therapy choices. Materials/methods: We enrolled 67 patients treated for a ruptured HCC (HCV 44, HBV 5, HBV + HCV 1, alcohol 2, others 15; naïve HCC 34, recurrent 33) from 2000 to 2013, and investigated their clinical background and prognosis. Results: Median survival time (MST) for all cases was 4 months. For patients who survived for more than 1 year after rupture, the percentages of Child-Pugh C and positive for portal vein tumor thrombosis (PVTT)/extrahepatic metastasis were less than for those who died within 1 year. Child-Pugh classification (A:B:C = 14:15:5 vs. 4:9:20, P < 0.001) was better, while the percentage of patients with multiple tumors was lower [19/34 (55.9%) vs. 29/33 (87.9%), respectively; P < 0.001] in the naïve group. The 1- and 3-year survival rates were better in the naïve as compared to the recurrent group (60.6% and 33.3% vs. 12.6% and 0%, respectively; P < 0.01). MST according to modified TNM stage (UICC 7th) calculated after exclusion of T4 factor of rupture, stage I was better than others (22.7 vs. (II) 2.2, (III) 1.2, and (IV) 0.7 months) (P = 0.010). Conclusion: In patients with a ruptured

To minimize selection bias, these patients were compared with 60 case-matched controls selected from a pool of 81 patients (in a 1:3 ratio who received TACE alone during the same period. The primary end point was overall survival (OS. The secondary end points were time to progression, disease control rate, and adverse events.Results: After a median follow-up period of 12.5 months (range, 1.03–44.23 months, the OS of the combined group was found to be significantly higher compared with the monotherapy group (14.9 vs 6.1 months, P=0.010. The time to progression was found to be significantly longer in the combined group (4.9 vs 2.4 months, P=0.016. Univariate and multivariate analyses revealed that the treatment allocation was an independent predictor of OS.Conclusion: Sorafenib plus TACE was well tolerated and was more effective in treating patients with advanced HCC and HVTT. Future trials with prospective larger samples are required to validate these results. Keywords: hepatocellular carcinoma, hepatic vein tumor thrombus, prognosis

    AIM: Tumor angiogenesis has been shown to be promoted by vascular endothelial growth factor (VEGF) via stimulating endothelial cell proliferation, migration, and survival.Blockade of VEGF signaling by different means has been demonstrated to result in reduced tumor growth and suppression of tumor angiogenesis in distinct tumor entities.Here, we tested a recombinant adenovirus, AdsFlt1-3,that encodes an antagonistically acting fragment of the VEGF receptor 1 (Flt-1), for systemic antitumor effects in pre-established subcutaneous CRC tumors in mice.METHODS: Murine colorectal carcinoma cells (CT26) were inoculated subcutaneously into Balb/c mice forin vivo studies. Tumor size and survival were determined. 293cell line was used for propagation of the adenoviral vectors.Human lung cancer line 4549 and human umbilical vein endothelial cells were transfected forin vitro experiments.RESULTS: Infection of tumor cells with AdsFlt1-3 resulted in protein secretion into cell supernatant, demonstrating correct vector function. As expected, the secreted sFlt1-3 protein had no direct effect on CT26 tumor cell proliferation in vitro, but endothelial cell function was inhibited by about 46% as compared to the AdLacZ control in a tube formation assay. When AdsFlt1-3 (5×109 PFU/animal) was applied to tumor bearing mice, we found a tumor inhibition by 72% at d 12 after treatment initiation. In spite of these antitumoral effects, the survival time was not improved.According to reduced intratumoral microvessel density in AdsFlt1-3-treated mice, the antitumor mechanism can be attributed to angiostatic vector effects. We did not detect increased systemic VEGF levels after AdsFlt1-3 treatment and liver toxicity was low as judged by serum alanine aminotransferase determination.CONCLUSION: In this study we confirmed the value of a systemic administration of AdsFlt1-3 to block VEGF signaling as antitumor therapy in an experimental metastatic colorectal carcinoma model in mice.

    2006-01-01

    Full Text Available Basal cell carcinoma (BCC is the most frequent type of skin cancer in humans, with cumulative exposure to ultraviolet radiation as an important risk factor for development of illness such as severe solar burns during childhood or adolescence. BCC is mainly located on sun-exposed sites, head and neck being the areas of more incidences; although nose, eyelids and periorbitary tissue are unfavorable due to cosmetic results that BCC involves. Tumors can be classified as nodular, superficial, micronodular, morphea variety, infiltrating, pigmented, metatypic and fibroepithelioma of Pinkus. Several treatment options such as surgical and nonsurgical are available. The goal of treatment is complete excision of the tumor with preservation of surrounding structures in a way aesthetically acceptable. Mohs′ micrographic surgery is the standard treatment for all nonmelanoma skin cancers. Orbital exenteration is also used for treatment of malignancies of ocular tissues, mainly squamous cell carcinoma, sebaceous cell carcinoma and BCC. The tissue beneath the surgical site can be left for second-intention granulation or covered with a cutaneous implant of partial thickness. The case of a 77-year-old patient is presented with BCC of inferior eyelid of 14 years′ duration, formerly managed with radiotherapy; however, due to recurrent illness and invasion to the maxillary antrum, he needed supraestructure maxillectomy with left orbital exenteration.

  16. The Role of Radiotherapy in the Treatment of Portal Vein Thrombosis from Advanced Hepatocellular Carcinoma

    International Nuclear Information System (INIS)

    Purpose: To determine the role of radiotherapy for the treatment of portal vein thrombosis (PVT) from hepatocellular carcinoma (HCC). Material and Methods: A retrospective analysis was performed on 70 patients that had been diagnosed with HCC and were treated with three-dimensional conformal radiotherapy (3D-CRT) for the PVT. The radiation dose ranged from 40 Gy to 60 Gy (median dose: 48 Gy) and the biological effective dose (BED) ranged from 31.3 Gy to 78.0 Gy10 (median dose: 61.6 Gy10). Response was determined by measuring the extent of the PVT on a CT image at 0, 1 and 3 months after completion of the radiotherapy. The median follow-up period was 9 months. Results: The response rate was 47.1% (33 patients), with two patients (2.9%) showing a complete response, 31 patients (44.3%) showing a partial response, and 35 patients (50%) showing stable disease or no response. The 1-year progression-free survival rate was 60%, and the median progression-free survival time was 17 months. The median overall survival time was 11 months, the median survival time in the responders was 15 months and in the nonresponders was 8 months (p=0.032). Four patients (5.7%) had transient liver function impairment during treatment. Radiation induced liver disease (RILD) was observed in only one patient (1.4%). Conclusion: Three-dimensional conformal radiotherapy for the treatment of PVT from advanced HCC was a relatively effective and safe method

    International Nuclear Information System (INIS)

    Aim: To investigate the clinical value of computed tomography (CT)-guided radioactive 125I seed implantation for the treatment of multiple pulmonary metastases of hepatocellular carcinoma (HCC). Materials and methods: From March 2007 to August 2010, 27 HCC patients with pulmonary metastases who had received computed tomography (CT)-guided radioactive 125I seed implantation were enrolled in the study. All patients had ≥2 metastatic lesions (mean diameter 2 ± 0.6 cm). Under CT-guidance, 125I seeds were implanted into the pulmonary metastases using the plane implantation technique. Results: Among 27 cases, complete response, partial response, stable disease, and progressive disease were observed in four, 15, six, and two cases, respectively, during 6–48 months (mean 20.1 ± 2.2 months) of follow-up CT. The response rate was 92.6%. The mean follow-up time after 125I implantation was 20.1 months (range 6–48 months). The survival rates at 1 and 2 years were 67% and 30.8%, respectively, with a median survival of 13.5 months. Side effects during the procedure included minor pulmonary effusions and pneumothorax. Pulmonary haemorrhage was observed in 18 cases and haemoptysis occurred in five patients. Radial shadows were observed in three cases on follow-up CT images, and seed migration in two cases on follow-up spiral CT images. Conclusion: CT-guided radioactive 125I seed implantation may be a safe and effective treatment option for HCC patients with multiple pulmonary metastases. - Highlights: • HCC patients with pulmonary metastases received CT-guided radioactive 125I seed implantation. • CT-guided radioactive 125I seed implantation may be a safe and effective treatment option. • Prospective studies are needed to confirm its value

  18. Relevance of intra operative radiotherapy in the treatment of uterine carcinoma - Lyon preliminary experience

    International Nuclear Information System (INIS)

    Aim: Retrospective analysis of Intra operative Radiotherapy (IORT) in recurrent uterine carcinoma (RUC) and prospective pilot study of IORT in advanced cervix cancer (ACC) with high risk of local failure. Patients-Treatments: (1) RUC: from 1988 to 1991, 34 patients with RUC have been treated. Primary cancer was: cervix uterus: 28, endometrium: six. Site of recurrence: centro pelvis: four, latero pelvis: 25, lombo aortic: five. Total gross resection was only possible in 12 patients. A dose of 15 to 22 Gy was given by IORT according to the residual tumour size. External beam irradiation was added in 16 patients; (2) ACC: January 1991 to November 1992, 20 patients were included in this pilot study, stage IIB: seven, stage III: 12, stage IV: 1. Preoperative retroperitoneal pelviscopy showed 13 pN1 patients and NMR imaging ten tumours of 6 cm or larger in diameter. Treatment started with concomitant pelvic irradiation (44 Gy) and one concomitant cycle of 5 Fu-CDDP, followed by a short course of high dose rate upper vagina brachytherapy (4Gy). Four weeks later a radical Wertheim operation was performed together with IORT on the lateral pelvis. Results: (1) RUC: overall survival (Kaplan Meier) at 4 years is 32% (±8). Local relapse in the field of IORT was observed in six patients. Grade 2-3 complications: six patients (radiation proctitis, neuritis, vertebral collapse, ureteral stenosis); (2) ACC: the median follow up is short (18 months). Four cases of pelvic relapse, no postoperative death. The first line radio chemotherapy was associated with two G3 early complications. Postoperative radiation complication was less than 10% G3. Discussion: promising results of IORT in RUC have been observed especially if no irradiation is given during the primary treatment. Good feasibility of the pilot study of IORT in ACC was also observed. It could be followed by a multicentric feasibility trial. (authors). 38 refs., 4 tabs., 1 fig

    Purpose: The purpose of this work was to examine outcomes in patients with T4 nasopharyngeal carcinoma (NPC) treated with intensity-modulated radiation therapy (IMRT). Methods and materials: Between 2007 and 2010, 154 patients with nonmetastatic T4 NPC were treated with IMRT to a total dose of 70 Gy in 33-35 fractions. In addition, 97 % of patients received concurrent platinum-based chemotherapy. The median follow-up time was 52.8 months. Results: The rates of 5-year actuarial locoregional control, distant metastasis-free survival, progression free-survival, and overall survival (OS) were 81.2, 72.2, 61.9, and 78.1 %, respectively. A total of 27 patients had locoregional recurrence: 85.2 % in-field failures, 11.1 % marginal failures, and 3.7 % out-of-field failures. Fourteen patients with locoregional recurrence received aggressive treatments, including nasopharyngectomy, neck dissection, or re-irradiation, and the 5-year OS rate tended to be better (61.9 %) compared to those receiving conservative treatment (32.0 %, p = 0.051). In patients treated with 1 course of radiotherapy, grade {>=} 3 toxicities of ototoxicity, neck fibrosis, xerostomia, epistaxis, and radiographic temporal lobe necrosis occurred in 18.2, 9.8, 6.3, 2.1, and 5.6 % of patients, respectively. Increased ototoxicity, osteonecrosis, severe nasal bleeding, and temporal necrosis were observed in patients treated by re-irradiation. Conclusion: IMRT offers good locoregional control in patients with T4 NPC. For patients with locoregional recurrence after definitive radiotherapy, aggressive local treatment may be considered for a better outcome. (orig.)

    The adrenocortical function of cane toads (Rhinella marina) exposed to different experimental procedures, as well as captured from different environments, was assessed by challenging the hypothalamic-pituitary-adrenal (HPA) axis. It was found that restriction stress as well as cannulation increased plasma corticosterone (B) levels for up to 12h. A single dose of dexamethasone (DEX 2mg/kg) significantly reduced B levels demonstrating its potential for use in the evaluation of the HPA axis in amphibia. We also demonstrate that 0.05 IU/g BW (im) of synthetic adrenocorticotropic hormone (ACTH) significantly increased plasma B levels in cane toads. Changes in size area of the cortical cells were positively associated with total levels of B after ACTH administration. We also found differences in adrenal activity between populations. This was assessed by a DEX-ACTH test. The animals captured from the field and maintained in captivity for one year at the animal house (AH) present the highest levels of total and free B after ACTH administration. We also found that animals from the front line of dispersion in Western Australia (WA) present the weakest adrenal response to a DEX-ACTH test. The animals categorized as long established in Queensland Australia (QL), and native in Mexico (MX), do not shown a marked difference in the HPA activity. Finally we found that in response to ACTH administration, females reach significantly higher levels of plasma B than males. For the first time the adrenocortical response in cane toads exposed to different experimental procedures, as well as from different populations was assessed systematically. PMID:26877241

    Full Text Available Lymphoepithelioma-like carcinoma (LELC of the urinary bladder is a rare variant, which can occur in a pure form or in conjunction with transitional cell carcinoma. Owing to the scarcity of reported cases, the optimum treatment is yet to be defined, although the benefits of chemotherapy are increasingly recognised. We present a case of a 64-year-old man with pure LELC, treated with trans-urethral resection of the bladder tumor (TURBT and primary gemcitabine and platinum-based chemotherapy. He remained free of disease at six-month follow-up cystoscopy. The case adds to the growing evidence for the efficacy of chemotherapy, coupled with TUR, as part of a bladder-preserving treatment option for LELC.

    Different methods of treatment have been debated over the years for Stage IB carcinoma of the cervix, especially in view of the results and complications. We have reviewed the experience of the Norwegian Radium Hospital for carcinoma of the cervix, Stage IB, for the years 1968, 1969, and 1970; most of the patients receive preoperative intrauterine and intravaginal radium, followed by radical hysterectomy and pelvic lymphadenectomy; if the nodes are involved, they also receive external pelvic irradiation. During this period, 437 patients had Stage IB; the 5 year survival was 80.2 per cent (not corrected). We focused our attention on lymphedema following such a method of treatment; of 402 patients operated upon, 23.4% developed lymphedema ranging from mild to moderate to severe; 20 patients (5%) had severe lymphedema; factors involved are analyzed.

    Sorafenib is an orally available kinase inhibitor with activity at Raf, PDGFβ and VEGF receptors that is licensed for the treatment of advanced renal cell carcinoma (RCC) and hepatocellular carcinoma (HCC). Current evidence-based post-nephrectomy management of individuals with localized RCC consists of surveillance-based follow up. The SORCE trial is designed to investigate whether treatment with adjuvant sorafenib can reduce recurrence rates in this cohort. Here we report an idiosyncratic reaction to sorafenib resulting in fatal hepatotoxicity and associated renal failure in a 62 year-old man treated with sorafenib within the SORCE trial. This is the first reported case of sorafenib exposure associated fatal toxicity in the adjuvant setting and highlights the unpredictable adverse effects of novel adjuvant therapies

  6. Treatment outcome of ductal carcinoma in situ patients treated with postoperative radiation therapy

    International Nuclear Information System (INIS)

    To evaluate the outcome of ductal carcinoma in situ (DCIS) patients who underwent surgery followed by radiation therapy (RT). We retrospectively reviewed 106 DCIS patients who underwent surgery followed by postoperative RT between 1994 and 2006. Ninety-four patients underwent breast-conserving surgery, and mastectomy was performed in 12 patients due to extensive DCIS. Postoperative RT was delivered to whole breast with 50.4 Gy/28 fx. Tumor bed boost was offered to 7 patients (6.6%). Patients with hormonal receptor-positive tumors were treated with hormonal therapy. The median follow-up duration was 83.4 months (range, 33.4 to 191.5 months) and the median age was 47.8 years. Ten patients (9.4%) had resection margin <1 mm and high-grade and estrogen receptor-negative tumors were observed in 39 (36.8%) and 20 (18.9%) patients, respectively. The 7-year ipsilateral breast tumor recurrence (IBTR)-free survival rate was 95.3%. Resection margin (<1 or ≥1 mm) was the significant prognostic factor for IBTR in univariate and multivariate analyses (p < 0.001 and p = 0.016, respectively). Postoperative RT for DCIS can achieve favorable treatment outcome. Resection margin was the important prognostic factor for IBTR in the DCIS patients who underwent postoperative RT.

    Full Text Available Hepatocellular carcinoma (HCC and liver metastases arecommon cancers worldwide. Recent imaging modalities havebeen able to detect HCC and liver metastases at an early stage,with surgical resection as the choice of management.However, because of poor liver reserve, co-existing liver cirrhosisand multiplicity of tumors, resection is only feasible in10-30% of HCC or liver metastases on presentation. Thus, variouslocal tumor ablation modalities are being developed toeffectively ablate small liver tumors. Of these, percutaneousethanol injection and radiofrequency (RF ablation (RFA arethe two best options because of their high effectiveness andminimal invasiveness. RFA has the particular advantage ofmore predictable ablation areas and fewer treatment sessionsrequired. It has been applied for local ablation of liver malignancysince 1990 and is currently widely accepted as an alternativeto resection in small, un-resectable or even resectable liver malignancies. Becausecurrent RF devices can only effectively ablate 3 cm tumors in a single RF electrode introduction,recent advances have focused exclusively on improving RF devices, including thedesign of electrodes and the algorithm to magnify the ablation zone in a single session orover a short duration. This review article updates results of RFA for HCC and liver metastasisin terms of complete ablation, local recurrence, overall survival, and recent advances inRFA for liver malignancy.

    Therapeutic management of hepatocellular carcinoma (HCC) is quite complex owing to the underlying cirrhosis and portal vein hypertension. Different scores or classification systems based on liver function and tumoral stages have been published in the recent years. If none of them is currently "universally" recognized, the Barcelona Clinic Liver Cancer (BCLC) staging system has become the reference classification system in Western countries. Based on a robust treatment algorithm associated with stage stratification, it relies on a high level of evidence. However, BCLC stage B and C HCC include a broad spectrum of tumors but are only matched with a single therapeutic option. Some experts have thus suggested to extend the indications for surgery or for transarterial chemoembolization. In clinical practice, many patients are already treated beyond the scope of recommendations. Additional alternative prognostic scores that could be applied to any therapeutic modality have been recently proposed. They could represent complementary tools to the BCLC staging system and improve the stratification of HCC patients enrolled in clinical trials, as illustrated by the NIACE score. Prospective studies are needed to compare these scores and refine their role in the decision making process. PMID:27330679

    Primary liver cancer is the fifth most common malignancy in the world and is a leading cause of cancer-related mortality. Available treatment for hepatocellular carcinoma (HCC), the commonest primary liver cancer, is rarely curative and there is a need to develop therapy that is more effective. Specific and powerful gene silencing that can be achieved by activating RNA interference (RNAi) has generated enthusiasm for exploiting this pathway for HCC therapy. Many studies have been carried out with the aim of silencing HCC-related cellular oncogenes or the hepatocarcinogenic hepatitis B virus (HBV) and hepatitis C virus (HCV). Proof of principle studies have demonstrated promising results, and an early clinical trial assessing RNAi-based HBV therapy is currently in progress. Although the data augur well, there are several significant hurdles that need to be overcome before the goal of RNAi-based therapy for HCC is realized. Particularly important are the efficient and safe delivery of RNAi effecters to target malignant tissue and the limitation of unintended harmful non-specific effects.

    Head and neck squamous cell carcinoma (HNSCC) is one of the most common cancers in the world with a close relation with some risk factor like, tobacco, alcohol consumption and more recently, with human papilloma virus infection. A review of the literature about actual prognosis and quality of life in HNSCC has been done analysing the results of surgical treatment and their impact on the quality of life of patients. Despite the elevated incidence of HNSCC, the survival rate has increased considerably over the last years thanks to the development of new surgical techniques, such as, microvascular reconstruction or transoral robotic surgery and the most accurate adjuvant radiochemotherapy. Even in bad prognosis cases, there are many options to take into account not only with curative expectation, even, keeping in mind the preservation of the quality of life of patients. Due to the improvement of the prognosis, the interest of surgeons has been focused on preserve the aesthetics, functional and psychosocial aspect of patients without a worsening of the main objective which is the curative result. Although prognosis of HNSCC has improved, further studies are necessary to understand the behaviour in every case and determine how the impact on the quality of life can be a useful tool to individualize the therapies.

    To evaluate the outcome of ductal carcinoma in situ (DCIS) patients who underwent surgery followed by radiation therapy (RT). We retrospectively reviewed 106 DCIS patients who underwent surgery followed by postoperative RT between 1994 and 2006. Ninety-four patients underwent breast-conserving surgery, and mastectomy was performed in 12 patients due to extensive DCIS. Postoperative RT was delivered to whole breast with 50.4 Gy/28 fx. Tumor bed boost was offered to 7 patients (6.6%). Patients with hormonal receptor-positive tumors were treated with hormonal therapy. The median follow-up duration was 83.4 months (range, 33.4 to 191.5 months) and the median age was 47.8 years. Ten patients (9.4%) had resection margin <1 mm and high-grade and estrogen receptor-negative tumors were observed in 39 (36.8%) and 20 (18.9%) patients, respectively. The 7-year ipsilateral breast tumor recurrence (IBTR)-free survival rate was 95.3%. Resection margin (<1 or ≥1 mm) was the significant prognostic factor for IBTR in univariate and multivariate analyses (p < 0.001 and p = 0.016, respectively). Postoperative RT for DCIS can achieve favorable treatment outcome. Resection margin was the important prognostic factor for IBTR in the DCIS patients who underwent postoperative RT.

    In this commentary, we review our experience with early glottic carcinomas in an attempt to identify points to consider when developing a treatment protocol and technical considerations in oncologic resection to maintain laryngeal function. We highlight several consistent themes: (1) difficult exposure is not always a contraindication to endoscopic resection; (2) depth of invasion may be apparent only intraoperatively; (3) radiation therapy should be offered for deeply invasive cancers requiring extensive cordectomy or for patients who cannot afford lengthy vocal downtime; however, (4) radiation therapy leads to acute dysphagia and collateral damage to the contralateral vocal fold that is avoided with surgery; (5) good voice can be obtained after healing if resection is limited to intramuscular cordectomy; (6) the key to optimal vocal results is adequate glottal closure; and (7) second look operations are occasionally necessary, and therefore preoperative counseling should include this possibility. Since both surgery and radiation therapy achieve excellent oncologic control, a patient-centered approach is preferred in management. PMID:24201059

  13. Intratumor heterogeneity, variability and plasticity: questioning the current concepts in classification and treatment of hepatocellular carcinoma.

    2016-04-01

    In the classical view, the formation of a primary tumor is the consequence of a mutational event that first affects a single cell that subsequently passes through a multitude of consecutive hyperplastic and dysplastic stages. At the end of this pathogenetic sequence a cell arises that is potentially able to expanse infinitely having capacity to form a homogenous tumor mass. In contrary to this clonal expansion concept, the majority of primary human tumors display already a startling heterogeneity that can be reflected in different morphological features, physiological activities, and genetic diversity. In the past it was speculated that this cancer cell plasticity within a tumor is the result of an adaptive process that is induced by specific inhibiting therapies. In regard to the formation of hepatocellular carcinoma (HCC) this dogma was once challenged in a recent study that analysed tumor areas that were taken from HCC patients without medical pretreatment. Most of the analyzed samples showed highly significant intratumor heterogeneity. This affected morphological attributes, immunohistochemical stainability of five tumor-associated markers [α-fetoprotein (AFP), EpCAM, CK7, CD44 and glutamine synthetase], and integrity of genes (β-catenin and p53) that are critically involved in the pathogenesis of HCC. Altogether, this study showed that intratumor heterogeneity is a frequent finding in HCC that may contribute to treatment failure and drug resistance in HCC patients. PMID:27115013

  14. Radiotherapy alone or with chemotherapy in the treatment of small-cell carcinoma of the lung

    International Nuclear Information System (INIS)

    Findings at one year are given of a study comparing radiotherapy (Rt) with radiotherapy followed by 3-drug chemotherapy (RtC3) in the treatment of small-cell carcinoma of the lung of limited extent. Over the 12-month period there was a significantly increased survival for the RtC3 patients. The median survival for the Rt series was 25 weeks and for the RtC3 series 43 weeks. There was evidence of recurrence of the primary cancer in 32% of the Rt and 26% of the RtC3 patients who died. Distant metastases appeared earlier and were more frequent in the Rt series. At 12 months only 8% of the Rt but 26% of the RtC3 patients were alive and free of metastases. Adverse reactions occurred much more frequently in the RtC3 series; the most common being nausea and vomiting and the most serious being marrow depression. No important differences were found in general condition, physical activity or respiratory function. It is concluded that radiotherapy plus chemotherapy was superior to radiotherapy alone, although chemotherapy did not protect patients from recurrence of primary growth. (author)

  15. Combination of irradiation, carcinostatics, and urokinase for the treatment of uterine cervical carcinoma

    International Nuclear Information System (INIS)

    In the treatment of carcinoma of the cervix uteri, histological changes were studied by dividing patients into 2 groups. One group was treated with radio-therapy and the other was treated with radiotherapy combined with chemotherapy, using antineoplastic agents which were used alone or in combination with urokinase. In regard to radiotherapy alone, Linac 10 MeV x-ray, 60Co-teletherapy, and radium contiguous irradiation were evaluated, and marked changes in cancerous parenchyma were seen with irradiation over 3000 rad. Irradiation of 3000 rad caused destruction of cancer cells, separation of the cells, inclusion of the focus, necrosis of hyalinization, and infiltration of neutrophils and lymphocytes. Approximately 4000 rad caused hyperplasia of the interstitial connective tissues, in addition to the above-mentioned changes. Approximately 5000 rad caused destruction and disappearance of cancer tissues, and approximately 6000 rad caused disappearance of the cancer cells which were then only connective or necrostic tissues. When radiotherapy was combined with BLM and FAMT therapies, degenerative changes were observed in many cases with irradiation of 1200 - 2400 mgh of radium or 1000 - 3000 rad of Linac or 60Co. The addition of urokinase tended to further accelerate the degeneration begun by BLM therapy. (Tsunoda, M.)

    Full Text Available A 10-year-old, intact male, pinscher was presented with unilateral bloodstained nasal discharge, sneezing, dyspnea, zygomatic arch deformity, submandibular lymph node increase, blindness in right eye, and exophthalmia. After clinical examination, it was found that the animal presented with upper respiratory tract dyspnea origin, possibly caused by an obstructive process. Complete blood count (CBC, ocular ultrasonography, thoracic radiographs, mandibular lymph node, and nasal sinus fine needle aspiration were performed. The right mandibular lymph node excisional biopsy was conducted and a tumor sample was obtained through the nasal fistula at hard palate. The material was processed, paraffin embedded, sectioned, and stained with hematoxylin and eosin. Immunohistochemical staining for cytokeratin (AE1/AE3, vimentin, and COX-2 was performed. After histopathological evaluation nasal carcinoma diagnosis was obtained. Chemotherapy was established with carboplatin 300 mg/m2 intravenously—four cycles with intervals of 21 days—and firocoxib 5 mg/kg orally every 24 hours for 7 months. After 7 months the treatment started, the animal presented with ataxia, vocalization, hyperesthesia, and anorexia. Due the clinical condition presented, the animal owner opted for performing euthanasia. The chemotherapy protocol was effective causing the disease stagnation, minimizing the clinical signs, and extending patient survival and quality of life.

  17. Radiation treatment of glottic squamous cell carcinoma, Stage I and II: analysis of factors affecting prognosis

    International Nuclear Information System (INIS)

    Purpose: At least in some European Countries, there is still considerable controversy regarding the choice between surgery and radiotherapy for the treatment of patients with early laryngeal-glottic carcinoma. Methods and Materials: Two hundred and forty-six patients with laryngeal-glottic neoplasms, Stage I-II, were treated with radical radiotherapy. Before radiotherapy the patients were evaluated to determine the surgical procedure of choice. Either 66-68.4 Gy (33-38 fractions) or 63-65 Gy (28-29 fractions) of radiation therapy (RT) were administered. The overall disease free survival was determined for each subgroup of patients. Univariate and multivariate analyses were performed to determine significant prognostic variables. Results: Five- and 10-year overall survival rates were 83 and 72%, respectively. At a median follow-up of 6 years 204 patients are alive and disease free. No patient developed distant metastases. One patient died of a large local recurrence, 38 patients died of causes unrelated to their tumor, and 3 patients were lost to follow-up. The multivariate analysis confirmed that performance status (PS), macroscopic presentation of the lesion, and persistence of dysphonia after radiotherapy are significant prognostic factors. Conclusions: According to the multivariate analysis, the patients with PS >80 and with exophytic lesions are eligible for radical RT. The surgical procedure proposed for each patient was not found to be an independent prognostic factor

    To study the treatment of experimental metastatic lung carcinoma by intratracheal injection of IL-18 gene recombinant adenovirus. Methods: (1)The mouse IL-18 mRNA was detected by RT-PCR, and the concentration of IL-18 and associated cytokines in lung lavages and blood were determined by ELISA at different time points after intratracheal injection of IL-18 recombinant adenovirus. (2)The lung metastasis nodes, mouse survival periods and survival rates were evaluated. NK activity and CTL activity were determined by 51Cr 4 h release method. Results: (1)IL-18 mRNA was detectable in lung tissue 6 h after intratracheal use of IL-18 recombinant adenovirus, and the concentration of IL-18 in lung lavage was higher than that in pelipheral blood. Neither IL-18 mRNA nor IL-18 was detectable in control group. (2) Intratracheal use of IL-18 recombinant adenovirus resulted in increased CTL and NK activity, longer survival time and higher survival rates compared with the control group, showing significant therapeutic effect on experimental lung metastasis. Conclusion: Intratracheal use of adenovirus vector containing IL-18 gene has therapeutic effect on the lung metastasis, denoting that gene therapy of lung diseases could be applied through airway directly with recombinant adenovirus.

    To determine the cytogenetic and genotoxic risk associated with therapeutic exposure to {sup 131}I (3.7 GBq) in 50 patients with differentiated thyroid carcinoma, we estimated the dosimetric index that reflects the dose to the bone marrow on day 4 and at several time intervals after exposure over a period of 2 years. The dosimetric index is 2 to 4 times higher for the dose to the bone marrow than the results based on MIRD calculations, which are derived from individuals with normal thyroid function and normal metabolic activity. This study shows that chromosomal anomalies induced by radiation persist over long periods of time (2 years) and that a retrospective biological dosimetry can be established in patients exposed to ionizing radiations. Blood samples taken at 3 and 6 months and 1 and 2 years after administration of {sup 131}I demonstrated more reciprocal translocations than those taken at 4 days and the presence of the dicentrics without the `accompagnateur` fragment. Stem cells produce new lymphocytes to make-up for the loss after {sup 131}I treatment. Direct estimation of the dose using our dosimetric index will provide a more accurate quantification of the risk incurred by exposure to {sup 131}I which until now, has been based exclusively on approximate statistical calculations of cumulative {sup 131}I doses.

  1. Clinical trials with cyclophosphamide and misonidazole combination for maintaining treatment after radiation therapy of lung carcinoma

    International Nuclear Information System (INIS)

    Fifteen patients with inoperable non oat cell lung carcinoma, who had already been treated with telecobalt therapy in the mediastinum-hilar region, were treated with continuing therapy with misonidazole (MISO) and cyclophosphamide (Cy). MISO was administered in single doses of 1000 mg/m2 and 500 mg/m2, orally. Cy was administered in single doses of 500 mg/m2 and 250 mg/m2, i.v. This treatment was given every 4 weeks. All patients (15/15) suffered from hyporexia, nausea and vomiting within 48 hours from administration; furthermore, 2 patients had hemoragic cystitis, 2 had peripheral neurotoxicity, 3 had fever, and 2 had serious nervous depression. Leukopenia occurred in all patients immediately after drug administration, although it was not present in any patient by the time of the next administration. This clinical trial was concluded in December 1981. The follow-up at 18 months shows 7/15 cases of relapse. Eight of 15 patients are alive with progression of disease from 8 to 18 months

    Patients with hepatocellular carcinoma (HCC) accompanyingportal vein tumor thrombosis (PVTT) haverelatively few therapeutic options and an extremely poorprognosis. These patients are classified into barcelona clinic liver cancer stage C and sorafenib is suggested asthe standard therapy of care. However, overall survival(OS) gain from sorafenib is unsatisfactory and bettertreatment modalities are urgently required. Therefore,we critically appraised recent data for the varioustreatment strategies for patients with HCC accompanyingPVTT. In suitable patients, even surgical resection can beconsidered a potentially curative strategy. Transarterialchemoembolization (TACE) can be performed effectivelyand safely in a carefully chosen population of patientswith reserved liver function and sufficient collateral bloodflow nearby the blocked portal vein. A recent metaanalysisdemonstrated that TACE achieved a substantialimprovement of OS in HCC patients accompanyingPVTT compared with best supportive care. In addition,transarterial radioembolization (TARE) using yttrium-90microspheres achieves quality-of-life advantages and isas effective as TACE. A large proportion of HCC patientsaccompanying PVTT are considered to be proper forTARE. Moreover, TACE or TARE achieved comparableoutcomes to sorafenib in recent studies and it was alsoreported that the combination of radiotherapy withTACE achieved a survival gain compared to sorafenib inHCC patients accompanying PVTT. Surgical resectionbasedmultimodal treatments, transarterial approachesincluding TACE and TARE, and TACE-based appropriatecombination strategies may improve OS of HCC patientsaccompanying PVTT.

  4. Endocavitary radiation for treatment of distal rectal carcinoma and twenty years experience

    International Nuclear Information System (INIS)

    Purpose/Objective: Sphincter preservation in the treatment of rectal cancer. Materials/Methods: The majority of patients with adenocarcinoma of the rectum are treated with radical surgical procedures. Lesions located in the distal rectum by abdominal perineal resection and those situated in the proximal portion of the rectum are treated by low anterior resection. Since the inception of endocavitary radiation therapy at Highland Hospital in July of 1973 to June of 1993, 227 patients were selected for curative endocavitary radiation. Stringent patient selection criteria was applied, (1) Well to moderately differentiated adenocarcinoma which is mobile on rectal examination and not larger than 5 cm in diameter, (2) The lesion must be no further than 11-12 cm from the anal verge, without any lymph node metastasis. The patients were staged by digital rectal examination, transrectal ultrasound, high resolution CT scan of the pelvis and abdomen and chest x-ray and received 10,000-12,000 cGy in approximately 4 fractions over a period of about 60 days. The treatments are separated by an interval of two or three weeks. Results: Local control has been achieved in 216 (95%) of patients. This is defined as no evidence of local disease on clinical examination or on laboratory or imaging studies. 35 patients failed from treatment (16 failed only distally). 9 patients died of disease. 59 patients died of intercurrent disease. The minimal follow up was 30 months. During the same period of time, 169 patients were treated with palliative intent only because they were not eligible for curative therapy due to more extensive disease and poor medical condition. Local control was achieved in 77 patients (45%) and good palliation was achieved in 76 patients (44%). 18 patients (11%) did not respond to treatment. Endocavitary radiation therapy has been utilized for treatment of villous adenomas from July 1973 to June of 1993. A total of 39 patients were treated for villous adenomas, 33 (85

    Full Text Available AIM: To evaluate the efficacy and the safety of azathioprine (AZA and buthionine sulfoximine (BSO by localized application into HepG2 tumor in vivo. METHODS: Different hepatoma and colon carcinoma cell lines (HepG2, HuH7, Chang liver, LoVo, RKO, SW-48, SW-480 were grown in minimal essencial medium supplemented with 10% fetal bovine serum and 1% antibiotic/antimycotic solution and maintained in a humidified 37 °C incubator with 5% CO2. These cells were pretreated with BSO for 24 h and then with AZA for different times. We examined the effects of this combination on some proteins and on cellular death. We also studied the efficacy and the safety of AZA (6 mg/kg per day and BSO (90 mg/kg per day in HepG2 tumor growth in vivo using athymic mice. We measured safety by serological markers such as aminotransferases and creatine kinase. RESULTS: The in vitro studies revealed a new mechanism of action for the AZA plus BSO combination in the cancer cells compared with other thiopurines (6-mercaptopurine, 6-methylmercaptopurine, 6-thioguanine and 6-methylthioguanine in combination with BSO. The cytotoxic effect of AZA plus BSO in HepG2 cells resulted from necroptosis induction in a mitochondrial-dependent manner. From kinetic studies we suggest that glutathione (GSH depletion stimulates c-Jun amino-terminal kinase and Bax translocation in HepG2 cells with subsequent deregulation of mitochondria (cytochrome c release, loss of membrane potential, and proteolysis activation leading to loss of membrane integrity, release of lactate dehydrogenase and DNA degradation. Some of this biochemical and cellular changes could be reversed by N-acetylcysteine (a GSH replenisher. In vivo studies showed that HepG2 tumor growth was inhibited when AZA was combined with BSO. CONCLUSION: Our studies suggest that a combination of AZA plus BSO could be useful for localized treatment of hepatocellular carcinoma as in the currently used transarterial chemoembolization method.

    study are the analysis of pre, per and post-operative outcome of patients undergoing right hepatectomy for liver metastasis of colorectal carcinoma, their prognosis and the feasibility of repeat hepatectomy in case of recurrence. METHODS: Fifty-seven patients that underwent right hepatectomy for liver metastasis of colorectal carcinoma between 1990 and 2000 at Hospital Beaujon, Paris, were retrospectively analysed. Post-operative follow-up period was 33-+25 months. RESULTS: There was no operative mortality. Blood transfusion was necessary in 29,8% of the patients and post-operative morbidity was 57,9%. Tumors larger than 5cm were detected in 59% of the cases and 78,5% had more than one tumor. Five-year survival rate was 43% and desease-free five-year survival was 23%. Hepatic recurrence was observed in 19,3% and repeat resections could be performed in 45,5% of them, with no mortality. CONCLUSIONS: Right hepatectomy for treatment of hepatic metastasis from colorectal cancer is safe, with low mortality and acceptable morbidity. Five-year survival rate is in according to literature. Repeat resections were feasible in half the cases of hepatic recurrence.

    A total of 29 patients with advanced renal cell carcinoma entered a pilot study of combination therapy with interferon alpha (IFN-alpha) and interferon gamma (IFN-gamma). IFN-alpha (HLBI: 3 x 10(6) IU, BALL 1:5 x 10(6) IU, IFN-alpha-2a: 9 x 10(6) IU or IFN-alpha-2b: 6 x 10(6) IU) was given intramuscularly every day and IFN-gamma (IFN-gamma-1a: 3 x 10(6) JRU) was given intravenously by drip infusion 3 times a week (every 2-3 days). The treatment was continued for 3 months as the induction therapy, and then the tumor response was evaluated. Of the 22 evaluable patients, 4 achieved a partial response (PR), 10 showed no change (NC), and in 8 the disease had progressed (PD) during the therapy. Thus, the overall response rate was 18.2% [95% confidence interval (CI) 2.1-34.3%]. A favorable response tended to be obtained in patients with good performance status or small pulmonary metastases, or in those who had no prior therapy with IFN-alpha, who received this treatment immediately subsequent to radical nephrectomy, or who received IFN-gamma as much as possible according to this regimen. Toxicity was evaluated in 28 patients: fever, general fatigue, anorexia, leukocytopenia and impaired liver function were frequently noted, and 3 patients were withdrawn from the study because of such adverse effects. In patients who had a PR or NC, the same dosage of IFN-alpha was continued to be given intramuscularly 2-3 times a week (every 2-4 days) as the maintenance therapy.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7474618

  8. Transarterial infusion chemotherapy with cisplatin plus S-1 for hepatocellular carcinoma treatment: a phase I trial

    International Nuclear Information System (INIS)

    In Japan, transarterial infusion chemotherapy using cisplatin (CDDP-TAI) is frequently used for advanced hepatocellular carcinoma (HCC). Moreover, oral chemotherapy with S-1, an oral fluoropyrimidine derivative, has also elicited promising responses in HCC patients. We determined the recommended dosage for CDDP-TAI plus S-1 combination therapy for advanced HCC. Twelve Child–Pugh class A or B patients with advanced HCC who met the eligibility criteria were enrolled in this phase I trial. Patients received CDDP-TAI (infusion, day 1) plus S-1 (oral administration, days 1–21) every 5 weeks until disease progression. Cisplatin (65 mg/m2) was administered with S-1 at 50 mg · m-2 day-1 (level 1, 3 patients), 60 mg · m-2 day-1 (level 2, 3 patients), or 80 mg · m-2 day-1 (level 3, 6 patients). The total number of treatment courses was 25 (median, 2 courses/patient; range, 1–6 courses). Dose-limiting toxicity was not observed in any patient at any level; therefore, the recommended dosage for cisplatin and S-1 in combination was level 3. Grade 3 adverse events were elevated alanine aminotransferase levels (2 patients), elevated aspartate aminotransferase levels (2 patients), anemia (1 patient), and decreased platelet counts (1 patient). Median progression-free survival and overall survival were 73 days and 328 days, respectively. The disease control rate was 58% (7/12); 17% (2/12) of patients achieved partial response and 42% (5/12) achieved stable disease. CDDP-TAI plus S-1 is safe for the treatment of HCC. The recommended dosage for further evaluation of this combination therapy in phase II studies is 65 mg/m2 CDDP and 80 mg/m2 S-1.

    AIM: To evaluate the feasibility and efficacy of percutaneous radiofrequency ablation (RFA) of the feeding artery of hepatocellular carcinoma (HCC) in reducing the blood-flow-induced heat-sink effect of RFA.METHODS: A total of 154 HCC patients with 177 pathologically confirmed hypervascular lesions participated in the study and were randomly assigned into two groups. Seventy-one patients with 75 HCCs (average tumor size, 4.3 ± 1.1 cm) were included in group A, in which the feeding artery of HCC was identified by color Doppler flow imaging, and were ablated with multiple small overlapping RFA foci [percutaneous ablation of feeding artery (PAA)] before routine RFA treatment of the tumor. Eighty-three patients with 102 HCC (average tumor size, 4.1 ± 1.0 cm) were included in group B, in which the tumors were treated routinely with RFA. Contrast-enhanced computed tomography was used as post-RFA imaging, when patients were followed-up for 1, 3 and 6 mo.RESULTS: In group A, feeding arteries were blocked in 66 (88%) HCC lesions, and the size of arteries decreased in nine (12%). The average number of punctures per HCC was 2.76 ± 1.12 in group A, and 3.36 ± 1.60 in group B ( P = 0.01). The tumor necrosis rate at 1 mo post-RFA was 90.67% (68/75 lesions) in group A and 90.20% (92/102 lesions) in group B. HCC recurrence rate at 6 mo post-RFA was 17.33% (13/75) in group A and 31.37% (32/102) in group B ( P = 0.04).CONCLUSION: PAA blocked effectively the feeding artery of HCC. Combination of PAA and RFA significantly decreased post-RFA recurrence and provided an alternative treatment for hypervascular HCC.

    International Nuclear Information System (INIS)

    Purpose: To determine the impact of primary or adjuvant chemotherapy and radiation (CRT) on the survival rates of patients with locally advanced vulvar carcinoma. Methods and Materials: Between 1973 and 1998, 54 patients with vulvar cancer were treated with radiation therapy, among which 20 received CRT, while 34 patients received radiation therapy (RT) alone. Of the 20 patients, 14 were treated for primary or recurrent disease (pCRT), and 6 after radical vulvectomy for high-risk disease (aCRT). Of the 34 patients, 12 were treated primarily (pRT) and 22 received adjuvant treatment (aRT). Chemotherapy consisted of 2 courses of 5-fluorouracil (5-FU) and mitomycin C administered during RT. Six patients received cisplatin in place of mitomycin C. In CRT groups, radiation was administered to the vulva, pelvic, and inguinal lymph nodes to a median dose of 45 Gy with additional 6-17 Gy to gross disease. In RT groups, the median dose to the microscopic diseases was 45 Gy. Nine patients received external beam boost and 16 patients received supplementary brachytherapy in the forms of 226Ra or 241Am plaques to sites of macroscopic disease. Results: Overall survival was superior in the patients treated with pCRT versus pRT with statistical significance (p 0.04). There was also a statistically significant improvement in disease-specific (p = 0.03) and relapse-free survival (p = 0.01) favoring pCRT. No statistically significant trends of improved survival rates favoring aCRT over aRT were observed. Conclusion: Concurrent radiation therapy and chemotherapy decreases local relapse rate, improves disease-specific and overall survival over RT alone as primary treatment for locally advanced vulvar cancer

  12. Comparison of two different thermal techniques for the treatment of hepatocellular carcinoma

    International Nuclear Information System (INIS)

    Purpose: To compare the safety and efficacy of radiofrequency ablation (RFA) and microwave ablation (MWA) in treating hepatocellular carcinoma (HCC) while conforming to the Milan criteria. Materials and methods: The study was approved by the Institutional Review Board, and informed consent was waived due to the retrospective study design. One hundred ninety-eight patients met the inclusion criteria and were included in the study. Eighty-five patients with 98 lesions received RFA, and 113 patients with 131 lesions underwent MWA. Complete ablation rates, local recurrence rates, disease-free survival rates, cumulative survival rates, and major complications were compared between the two treatment groups. Results: Complete ablation rates were 99.0% for RFA and 98.5% for MWA (P = 1.000). Local recurrence rates were 5.2% for RFA and 10.9% for MWA (P = 0.127). Disease-free survival rates at 1, 2, 3, and 4 years were 80.3%, 61.8%, 39.5%, and 19.0% in the RFA group and 75.0%, 59.4%, 32.1%, and 16.1% in the MWA group, respectively (P = 0.376). Cumulative survival rates at 1, 2, 3, and 4 years were 98.7%, 92.3%, 82.7%, and 77.8% in the RFA group and 98.0%, 90.7%, 77.6%, and 77.6% in the MWA group, respectively (P = 0.729). Major complication rates were 2.4% and 2.7% in the RFA group and the MWA group, respectively (P = 1.000). There were no patient deaths due to treatment. Conclusion: RFA and MWA have the same clinical value in treating HCC conforming to the Milan criteria. RFA and MWA are both safe and effective techniques for HCC as clinical application

  13. Preoperative radiotherapy in rectal signet-ring cell carcinoma - magnetic resonance imaging and treatment outcome

    International Nuclear Information System (INIS)

    Background. Signet-ring cell carcinoma (SRCC) is an uncommon tumor entity in rectal cancer, often considered to be resistant to non-surgical therapy. In locally advanced primary or recurrent rectal cancer, diagnostic information from magnetic resonance imaging (MRI) is considered superior in planning the optimal treatment strategy, which usually includes preoperative radiotherapy. The recognition of MRI features that correlate with the radiation response might ultimately be used to select patients for tailored treatment and, in addition, avoid potentially toxic therapy in non-responding patients. Material and methods. In a cohort of 120 rectal cancer patients who had received preoperative radiotherapy (50 Gy in 2 Gy fractions), six patients were noted to have SRCC tumor differentiation. Initial diagnostic MRI examination included assessment of local T- and N-stage and tumor morphology. Histological tumor response was subsequently assessed in the resected specimens, and postoperative follow-up data was compiled until disease recurrence. Results. Following the preoperative radiotherapy, two distinctly different histological responses - complete response (ypT0N0) or no response - were observed. Extensive mesorectal lymph node metastasis (N2 disease) at the pretreatment MRI examination was unambiguously associated with lack of response and rapid development of disseminated disease. Importantly, patients with complete response have been observed for 23-52 months postoperatively without evidence of recurrent disease. Discussion. Our review may suggest that patients with locally advanced growth of rectal SRCC, despite poorer outcome when compared to patients with conventional-type rectal adenocarcinoma, when presenting limited lymph node disease should be offered preoperative radiotherapy in a tentatively curative setting

  14. Concurrent chemoradiotherapy in locoregionally advanced nasopharyngeal carcinoma: Treatment outcomes of a prospective, multicentric clinical study

    International Nuclear Information System (INIS)

    Background and purpose: To evaluate long-term outcome in locoregionally advanced nasopharyngeal carcinoma (NPC) treated with intensity-modulated radiation therapy (IMRT) and concurrent chemotherapy. Material and methods: Between January 2006 and August 2008, 249 patients with stage III–IVb NPC were treated by IMRT plus concurrent chemotherapy in this multicenter prospective study. Results: With a mean follow-up of 54.1 months, the 5-year actuarial rates of overall survival (OS), local recurrence-free survival (LRFS), regional recurrence-free survival (RRFS), and distant metastasis-free survival (DMFS) were 78.4%, 86.8%, 88.4%, 78.0%, respectively. There were 29 local recurrences, 25 regional recurrences and 52 distant metastases, respectively. Distant metastasis is the main cause of treatment failure. N-stage was an independent prognostic factor for LRFS, RRFS, DMFS and OS. Acute toxicity ⩾grade III mainly consisted of mucositis (34.9%), neutropenia (11.2%), xerostomia (5.6%), and dermatitis (5.2%). The main documented late toxicity was xerostomia, and the severity of xerostomia decreased over time. At 24 months after treatment, 13.2% of patients had grade 2 xerostomia, and none had grade 3 or 4 xerostomia. Conclusions: IMRT with concurrent cisplatin chemotherapy resulted in encouraging rates of local and distant control and overall survival with acceptable rates of acute and limited rates of late toxicity in patients with locoregionally advanced NPC. Distant metastasis remained the main cause of failure. More effective systemic therapy should be explored for patients with advanced N-stage

    AIM: To evaluate long-term outcomes of radiofrequency (RF) ablation as first-line therapy for single hepatocellular carcinoma (HCC) ≤ 3 cm and to determine survival and prognostic factors. METHODS: We included all 184 patients who underwent RF ablation as a first-line treatment for single HCC ≤ 3 cm between April 2005 and December 2013. According to the criteria of Livraghi, the 184 patients were divided into two groups: those suitable for surgical resection (84 cases) and those unsuitable for surgical resection (100 cases). The primary endpoints were the overall survival (OS) rate and safety; the secondary endpoints were primary technique effectiveness and recurrence rate. RESULTS: There were 19 (10.3%) cases of ablation related minor complications. The complete tumor ablation rate after one RF session was 97.8% (180/184). The rate of local tumor progression, extrahepatic metastases and intrahepatic distant recurrence were 4.9% (9/184), 9.8% (18/184) and 37.5% (69/184), respectively. In the 184 patients, the 1-, 3-, and 5-year OS rates were 99.5%, 81.0%, and 62.5%, respectively. The 1-, 3-, and 5-year OS rates were 100%, 86.9%, and 71.4%, respectively, in those suitable for surgical resection and 99.0%, 76.0%, and 55.0%, respectively, in those unsuitable for surgical resection (P = 0.021). On univariate and multivariate analyses, poorer OS was associated with Child-Pugh B class and portal hypertension (P < 0.05). CONCLUSION: RF ablation is a safe and effective treatment for single HCC ≤ 3 cm. The OS rate of patients suitable for surgical resection was similar to those reported in surgical series.

    Full Text Available BACKGROUND: Even with early stage hepatocellular carcinoma (HCC, patients are often ineligible for surgical resection, transplantation, or local ablation due to advanced cirrhosis, donor shortage, or difficult location. Stereotactic body radiation therapy (SBRT has been established as a standard treatment option for patients with stage I lung cancer, who are not eligible for surgery, and may be a promising alternative treatment for patients with small HCC who are not eligible for curative treatment. MATERIALS AND METHODS: A registry database of 93 patients who were treated with SBRT for HCC between 2007 and 2009 was analyzed. A dose of 10-20 Gy per fraction was given over 3-4 consecutive days, resulting in a total dose of 30-60 Gy. The tumor response was determined using dynamic computed tomography or magnetic resonance imaging, which was performed 3 months after completion of SBRT. RESULTS: The median follow-up period was 25.6 months. Median size of tumors was 2 cm (range: 1-6 cm. Overall patients' survival rates at 1 and 3 years were 86.0% and 53.8%, respectively. Complete and partial tumor response were achieved in 15.5% and 45.7% of patients, respectively. Local recurrence-free survival rate was 92.1% at 3 years. Most local failures were found in patients with HCCs > 3 cm, and local control rate at 3 years was 76.3% in patients with HCC > 3 cm, 93.3% in patients with tumors between 2.1-3 cm, and 100% in patients with tumors ≤ 2 cm, respectively. Out-of-field intrahepatic recurrence-free survival rates at 1 and 3 years were 51.9% and 32.4%, respectively. Grade ≥ 3 hepatic toxicity was observed in 6 (6.5%. CONCLUSIONS: SBRT was effective in local control of small HCC. SBRT may be a promising alternative treatment for patients with small HCC which is unsuitable for other curative therapy.

  18. Increased treatment-related mortality with additional cisplatin-based chemotherapy in patients with nasopharyngeal carcinoma treated with standard radiotherapy

    International Nuclear Information System (INIS)

    Background and purposes: We performed a meta-analysis of randomized controlled trials (RCTs) to determine the overall risk of treatment-related death associated with additional cisplatin-based chemotherapy in patients with nasopharyngeal carcinoma treated with standard radiotherapy. Material and methods: Eligible studies included RCTs in which cisplatin-based chemotherapy in combination with radiotherapy was compared with radiotherapy alone. Statistical analyses were conducted to calculate the summary incidence rates, relative risks (RRs), and 95% confidence intervals (CIs) using fixed- or random-effects models based on the heterogeneity of included studies. Results: A total of 2829 patients from 13 RCTs were included in this study. The overall incidence for treatment-related death in chemoradiotherapy and radiotherapy treated patients was 1.7% and 0.8%. Compared to radiotherapy alone, radiotherapy plus cisplatin-based chemotherapy significantly increased the risk of treatment-related mortality. On subgroup analyses, no difference was found in treatment-related mortality between different timings of chemotherapy and chemotherapeutic agents. Adding cisplatin-based chemotherapy was associated with higher incidences of severe acute toxicity. Conclusions: Cisplatin-based chemotherapy plus radiotherapy increased the risk of treatment-related death and severe acute toxicity, compared with radiotherapy alone. Better management of treatment toxicity might improve the therapeutic gain in patients with nasopharyngeal carcinoma.

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

    International Nuclear Information System (INIS)

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