    Full Text Available Squamous cell carcinoma of the larynx continues to be the commonest head and neck cancer in many Western countries. The larynx plays a key role for many essential functions, including breathing, voice production, airway protection, and swallowing. The goals of laryngeal cancer treatment are thus to provide best possible oncologic control, while optimizing functional outcomes. In recent decades, the treatment paradigm for advanced laryngeal cancer has shifted from one of primary surgery (total laryngectomy as gold standard, toward non-surgical organ-preserving treatment using radiotherapy or chemoradiotherapy. However, concerns have emerged regarding functional outcomes after chemoradiotherapy, as well as possible decreased overall survival in patients with laryngeal cancer. The purpose of the present review is to review surgical and non-surgical options for treatment of advanced laryngeal cancer, as well as the evidence supporting each of these.

    The diagnostic capabilities of nuclear medicine imaging in the detection and assessment of the spread of laryngeal/hypopharyngeal cancer were studied. A total of 40 patients with histologically verified laryngeal and hypopharyngeal cancer and 20 patients with benign laryngeal lesions were included into the study. Submucosal injections of 99mTc-MIBI and 99mTc-Alotech were made around the tumor. Single photon emission computed tomography (SPECT) was performed 20 minutes after the injection of 99mTc-MIBI. Sentinel lymph nodes (SLNs) were detected in 26 patients. In 18 hours after the injection of 99mTc-Alotech, SPECT was performed. In 24 hours after the injection of 99mTc-Alotech, intraoperative SLN detection was performed using Gamma Finder II. SPECT with 99mTc-MIBI revealed laryngeal and hypopharyngeal tumors in 38 of the 40 patients. The 99mTc-MIBI uptake in metastatic lymph nodes was visualized in 2 (17%) of the 12 patients. Twenty eight SLNs were detected by SPECT and 31 SLNs were identified using the intraoperative gamma probe. The percentage of 99mTc-Alotech in the SLN was 5-10% of the radioactivity in the injection site by SPECT and 18-33% by intraoperative gamma probe detection. Thus, SPECT with 99mTc-MIBI is an effective tool for the diagnosis of laryngeal/hypopharyngeal cancer. The sensitivity, specificity and accuracy of this technique were 95%, 80% and 92%, respectively. The use of 99mTc-Alotech for the detection of SLNs in patients with laryngeal/hypopharyngeal cancer is characterized by 92.8% sensitivity.

    The aim of the study was to assess the efficacy of radiotherapy alone in patients with locally advanced laryngeal cancer T3 - T4, and to establish the prognostic value of the size and the location of the extra laryngeal infiltrations and of emergency tracheostomy. 296 patients with advanced squamous cell cancer of the larynx were radically treated with radiotherapy alone in Center of Oncology in Gliwice between the years 1990 and 1996. There were 221 cases of supraglottic cancer (75%) and 75 of glottic cancer (25%). The stages were as follows: supraglottic cancer: T3 - 113 (51%), T4 - 108 (49%), glottic cancer: T3 - 69 (92%), T4 - 6 (8%). Positive neck nodes were found in 100 patients with supraglottic cancer (45%), and only in 11 patients with glottic cancer (15%). In cases of extra laryngeaI invasion (T4) the pyriform recess was involved in 33%, the base of tongue and valleculae glosso-epiglotticae in 30%, the hypopharyngeal wall in 9% of cases, while a massive involvement of the larynx, the pyriform recess and the base of the tongue was found in 6% of patients. Cartilage involvement was suspected in 22% of patients. Thirty six patients (12%) underwent emergency tracheostomy. Generally, the 3-year local control rate (LC) and disease free survival rate (DSF) were 46% and 41%, respectively. The probability of LC was similar in both supraglottic and glottic cancer: 44% and 47.5% respectively. The presence of involved neck nodes significantly decreased LC and DFS rates in both groups (about 20%). For stage T4 laryngeal cancer the LC rate was correlated with the location of the extra laryngeal infiltrations. Best prognosis was connected with the suspicion of cartilage infiltration - 56% of 3-year LC rate. The worst results were noted in cases of massive infiltrations spreading from larynx through the hypopharynx - 13.5% of 3-year LC rate. Emergency tracheostomy before radiotherapy was very significantly linked to poorer treatment results. The 3-year LC rate in

    Twenty-five patients with advanced laryngeal cancer were treated with twice-a-day fractionated radiotherapy (TDFR) to a total dose of 65 Gy to 82 Gy combined with chemotherapy of CDDP and 5-FU between 1994 and 1997. Twenty-two cases (88%) became complete response and 9 cases recurred. The relapse-free rate at 2 years was 49.8%. The laryngeal conserving rate at 2 years was 71.0%, the actuarial 2-year survival rate was 89.9%. In induction chemotherapy (12 cases) no severe toxicity has been observed. In TDFR with concurrent chemotherapy (22 cases), grade 3 hematological toxicity was observed in 4 cases and grade 4 mucosal toxicity in 16 cases. Based on this investigation, it is concluded that TDFR with chemotherapy is a promising modality for advanced laryngeal cancer and toxicity is acceptable. (author)

    Purpose: To perform a retrospective review of laryngeal/hypopharyngeal carcinomas treated with concurrent chemotherapy and intensity-modulated radiotherapy (IMRT). Methods and Materials: Between January 2002 and June 2005, 20 laryngeal and 11 hypopharyngeal carcinoma patients underwent IMRT with concurrent platinum-based chemotherapy; most patients had Stage IV disease. The prescription of the planning target volume for gross, high-risk, and low-risk subclinical disease was 70, 59.4, and 54 Gy, respectively. Acute/late toxicities were retrospectively scored using the Common Toxicity Criteria scale. The 2-year local progression-free, regional progression-free, laryngectomy-free, distant metastasis-free, and overall survival rates were calculated using the Kaplan-Meier method. Results: The median follow-up of the living patients was 26 months (range, 17-58 months). The 2-year local progression-free, regional progression-free, laryngectomy-free, distant metastasis-free, and overall survival rate was 86%, 94%, 89%, 92%, and 63%, respectively. Grade 2 mucositis or higher occurred in 48% of patients, and all experienced Grade 2 or higher pharyngitis during treatment. Xerostomia continued to decrease over time from the end of RT, with none complaining of Grade 2 toxicity at this analysis. The 2-year post-treatment percutaneous endoscopic gastrostomy-dependency rate for those with hypopharyngeal and laryngeal tumors was 31% and 15%, respectively. The most severe late complications were laryngeal necrosis, necrotizing fascitis, and a carotid rupture resulting in death 3 weeks after salvage laryngectomy. Conclusion: These preliminary results have shown that IMRT achieved encouraging locoregional control of locoregionally advanced laryngeal and hypopharyngeal carcinomas. Xerostomia improved over time. Pharyngoesophageal stricture with percutaneous endoscopic gastrostomy dependency remains a problem, particularly for patients with hypopharyngeal carcinoma and, to a lesser

    Pneumothorax is a possible complication of tracheostomy. We report a rare case of bilateral pneumothoraces resulting from tracheostomy in an advanced laryngeal cancer patient. A 59-year-old man was referred to our clinic for evaluation and treatment of laryngeal tumor. Laryngeal endoscopy showed limited movement of bilateral vocal cords, and computed tomography revealed a tumor lesion extending from the vocal cords to the subglottic area. Three days after the first visit, the patient developed respiratory difficulty, and we elected to perform emergency tracheostomy for airway management. Immediately after the start of the procedure, he began hyperventilating, and complained of respiratory discomfort and chest pain. We then recognized a mediastinal air leak, and we suspected pneumothorax resulting from the tracheostomy. Chest X-ray showed bilateral pneumothoraces; therefore, we inserted bilateral chest drainage tubes, which stabilized his respiratory condition. We speculated that the pathogenesis of the bilateral pneumothoraces was weakened alveolar walls secondary to long-term smoking, and a significant rise in airway pressure because of airway constriction by the neck-extended position and hyperventilation, during tracheostomy.

    The objective was the comparison of the quality of life in patients with advanced laryngeal cancer treated with organ preservation versus surgical treatment. We performed a systematic review in the databases MedLine, EMBASE, and PubMed (2014 1991) and Web of Science (2012 - 2014). The search terms were: Laryngeal cancer, organ preservation, chemotherapy, laryngectomy, treatment outcomes and quality of life. Systematic reviews, meta-analysis, reports of health technology assessment and comparative studies with control group, published in Spanish, French or English were included. The selection and quality assessment was made by two researchers. The criteria of the Cochrane Collaboration were used to assess the risk of bias and Scottish Intercollegiate Guidelines Network (SIGN) for the level of evidence. Of the 208 studies identified in the search, three were included a clinical trial and two observational studies, with a total of 211 patients. Quality and level of evidence was low. The results were contradictory, on occasion they favoured surgery, and on other occasions chemotherapy, but in general there were no statistical differences between the treatments. The studies were heterogeneous, with different methodology, undersized, limitations in quality with high risk of bias and use of different measurement scales. There are not enough studies of quality to establish differences in the quality of life in patients with advanced laryngeal cancer according to the treatment received.

    Combinations of treatment modalities for locally extensive carcinomas of the larynx constitute the standard of care. Advanced 'horseshoe' anterior commissure laryngeal cancer (HACLC) is a disease entity that has not received much attention in the literature. The aims of this study were to evaluate prolonged survival in patients after standard combined therapy for HACLC and to identify clinicopathological factors influential towards an extended outcome. Fourteen patients (10-year survivors) with stage III or IV laryngeal cancer involving the anterior commissure and both true vocal cords were treated with total laryngectomy (and postoperative radiotherapy in 11 individuals). During follow-up, ranging from 123 to 256 months, locoregional recurrent disease and distant metastasis were not observed. Complications after therapy were manageable and few. The long-term survivors were particularly difficult to characterize. The optimal treatment for advanced HACLC has not been clarified; however, in this study, total laryngectomy and the indicated use of postoperative radiotherapy, were successful in achieving long-term disease-free survival. Predictive factors for longevity were not detected in this limited experience. Copyright© 2016 International Institute of Anticancer Research (Dr. John G. Delinassios), All rights reserved.

    Introduction: Organ-preservation treatment approaches for advanced laryngeal cancer patients that use combination chemoradiotherapy result in cure rates similar to primary laryngectomy with postoperative radiotherapy. In the national VA Larynx Cancer Trial, successful organ preservation was associated with an overall improvement in quality of life but not in subjective speech compared with long-term laryngectomy survivors. As part of a Phase II clinical trial, a prospective study of speech and swallowing results was conducted to determine if larynx preservation is associated with improved voice and swallowing compared with results in patients who require salvage laryngectomy. Subjects: A total of 97 patients with advanced laryngeal cancer (46 Stage III, 51 Stage IV) were given a single course of induction chemotherapy (cisplatin 100 mg/m 2 on Day 1 and 5-FU 1,000 mg/m 2 /day x 5 days), followed by assessment of response. Patients with less than 50% response underwent early salvage laryngectomy, and patients with 50% or better response underwent concurrent chemoradiation (72 Gy and cisplatin 100 mg/m 2 on Days 1, 22, and 43), followed by two cycles of adjuvant chemotherapy (DDP/5-FU). Direct laryngoscopy and biopsy were performed 8 weeks after radiation therapy to determine final tumor response. Late salvage surgery was performed on patients with persistent or recurrent disease. Methods: Completed survey data on voice and swallowing utilizing the Voice-Related Quality of Life Measure (V-RQOL) and the List Performance Status Scale for Head and Neck Cancer Patients (PSS-HN) were obtained from 56 patients who were alive and free of disease at the time of survey, with a minimum follow-up of 8 months. Comparisons were made between patients with an intact larynx (n = 37) vs. laryngectomy (n = 19), as well as early (n = 12) vs. late salvage laryngectomy (n = 7). Multivariate analysis was performed to determine factors predictive of voice and swallowing outcomes. Overall 3

    Purpose: To determine the rates of organ preservation and function in patients with advanced laryngeal and hypopharyngeal carcinomas treated with concurrent chemoradiotherapy (CRT). Methods and Materials: Between April 1999 and September 2005, 82 patients with advanced laryngeal (67%) and hypopharyngeal carcinomas (33%) underwent conventional radiotherapy and concurrent platinum-based chemotherapy with curative intent. Sixty-two patients were male (75.6%). The median age was 59 years. Eighteen patients (22%) were in Stage III and 64 (78%) were in Stage IV. The median radiation dose was 70 Gy. The median potential follow-up was 3.9 years. Results: Overall survival and disease-free survival were respectively 63% and 73% at 3 years. Complete response rate from CRT was 75%. Nineteen patients (23%) experienced significant long-term toxicity after CRT: 6 (7.3%) required a percutaneous endoscopic gastrostomy, 5 (6%) had persistent Grade 2 or 3 dysphagia, 2 (2.4%) had pharyngoesophageal stenosis requiring multiple dilations, 2 (2.4%) had chronic lung aspiration, and 7 (8.5%) required a permanent tracheostomy. Four patients (4.9%) underwent laryngectomy without pathologic evidence of disease. At last follow-up, 5 (6%) patients were still dependent on a gastrostomy. Overall, 42 patients (52%) were alive, in complete response, with a functional larynx and no other major complications. Conclusions: In our institution, CRT for advanced hypopharyngeal and laryngeal carcinoma has provided good overall survival and locoregional control in the majority of patients, but a significant proportion did not benefit from this approach because of either locoregional failure or late complications. Better organ preservation approaches are necessary to improve locoregional control and to reduce long-term toxicities.

    To determine the functional disabilities and overall quality of life of patients operated for advanced (Stages III-IV) or recurrent squamous cell carcinomas (SCCA) after radiation therapy of the (pharyngo)larynx. From 1984 to 1997, 135 patients were consecutively treated for SCCA of the (pharyngo)larynx. There were 118 men and 17 women with a mean age of 60 years. The University of Washington QOL questionnaire (UW-QOL) (Deleyiannis et al) was administered to 19 long term survivors. Self-administered scale consisting of nine domains affected by treatment for head and neck cancer: pain, physical appareance, global activity, entertainement, employment, chewing, swallowing, speech and shoulder function. For each patient, a total score and weighted score were determined. Descriptive statistics were used. 9/19 patients reported that compared with one year prior to the diagnosis of cancer their general health was the same. Pain resolved in 78%; the physical appearance was juged not modified in 52% of the cases. Chewing and swallowing functions were respected in 94% of the cases. These functions were considered as very important in 53% and 68% respectively. Five patients are still at work; 11 patients retired. Work was considered as very important for 9/19 patients. Speech rehabilitation permitted a modified but well understandable communication in 63% of the cases. This function was considered by 88% of the patients as very important. Finally, 73% of the patients (14/19) reported having a good to excellent overall QOL. Though disabling, pharyngolaryngectomies do not necessarily translate into worse overall QOL; ultimate disabilities are widely variable. Many factors such family, friends, personal leisure, activities, employement, cultural habits were important and depending on each patient in enjoyement of life's estimation.

    Purpose: To determine the safety and radiation-enhancing effect of sodium glycididazole in laryngeal squamous cell carcinoma (stage T3-4,N0-3,M0) with conventional radiotherapy. Patients and methods: Patients with locoregional advanced laryngeal cancer (stage T3-4,N0-3,M0) were included: group 1(control, n = 30)were not administered of sodium glycididazole; group 2 (test, n = 30) received sodium glycididazole at a dose of 700 mg/m2 intravenous infusion 30 minutes before radiotherapy three times a week. Surrogate end-points of efficacy were tumor and nodal size. Safety parameters were vomiting, nausea, mucositis, laryngeal edema, esophagus and skin reaction, dysphagia, dyspnea, neurological deficit. Patients were evaluated weekly during treatment for 7 weeks and thereafter monthly for 3 months. Results: In the test, the overall response rate was 88.89% (95% CI, 71.00-97.00%) at 7 weeks and 92.59% (95% CI, 76.00 to 99.00%) at 1 month of follow-up. In the control, the overall response rate was 62.5% (95% CI, 41.00 to 81.00%) at 7 weeks and 58.33% (95% CI, 37.00 to 78.00%) at 1 month of follow-up. The short-term locoregional response rate was better in the test group at 7 weeks (p = 0.027) and at 1 month (p = 0.005) of follow-up. The test group had significantly more nausea and vomiting in weeks 1 (p = 0.047), 2 (p = 0.007), and 3 (p = 0.01) of treatment. Conclusions: The study indicates sodium glycididazole is an effective radiation-enhancing agent that improves short-term locoregional control and is well tolerated in patients with loco regionally advanced laryngeal cancer.

    Laryngeal cancer is the commonest head and neck cancer seen at the Ear Nose and Throat (ENT) Unit Korle Bu Teaching Hospital. The aim of this study was to determine the number of cases of laryngeal cancer seen at the Korle Bu Teaching Hospital, establish epidemiological parameters of the disease and to outline preventive measures. One hundred and fifteen (115) patients who were managed for laryngeal cancer from 1st January 1998 to 31st December 2003 were studied retrospectively with respect to age, sex, duration of symptoms at presentation, risk factors, symptoms complex, histopathology, stage of tumor, details of treatment offered and follow up. The age range was 17-85 years with a mean of 55.5 years (SD10.7). Majority of the patients (90.4%) were above 40 years. The commonest symptom at presentation was dysphonia. A significant proportion of cases (37.3%) presented with locally advanced disease. The commonest histological type of laryngeal tumour seen was squamous cell carcinoma. The treatment offered consisted of radiotherapy for 83 (79.8%) patients and total laryngectomy with neck dissection when necessary for 17 (16.3%) patients who also had postoperative radiotherapy. Only 58 (69.9%) patients completed radiotherapy treatment and in all 32 (24.3 %) patients did not report for any treatment. Majority of patients failed to report for post treatment follow-up. We conclude that significant number of patients with laryngeal cancer presented with locally advanced disease and dysphonia was the commonest symptom. (au)

    Hypothyroidism following total laryngectomy or radiotherapy treatment for laryngeal cancer is not a rare event, especially in advanced stages. There are no reports on the incidence of hypothyroidism in patients who received chemotherapy and radiotherapy. The objective of this study is to determine the incidence of thyroid dysfunction in a group of patients with laryngeal cancer who underwent surgery as sole treatment, total laryngectomy or radiotherapy alone, and patients with combined treatment: surgery plus radiotherapy, concomitant chemoradiation therapy and chemoradiation therapy plus salvage surgery. A prospective study of patients diagnosed with laryngeal cancer whose serum TSH and T4 levels were evaluated in a serial fashion. 70 patients with laryngeal cancer were studied; the average age at diagnosis was 70.2 years. Male patients were more affected, with a men-women ratio of 3.6:1. Glottic localization was the most frequent (44%). 64% of tumors were locally advanced carcinomas and 51% received multimodal treatment. 45 patients (63%) were diagnosed with hypothyroidism; 49% of the patients with subclinical hypothyroidism, and 51% with clinical hypothyroidism. Hypothyroidism is a complication following treatment for laryngeal cancer. It is recommended to evaluate the thyroid function periodically for timely detection.

    Between 1989 and 2003, we treated 129 patients with T1 and T2 laryngeal cancers. The purpose of this study was to estimate the management of T1 and T2 laryngeal cancers, referring to the relationship with the T classification, subtype, treatment, prognosis and laryngeal preservation. The treatment plan for T1 and T2 laryngeal cancers is fundamentally radiotherapy. To raise the laryngeal preservation rate, concurrent chemoradiotherapy by FAR therapy, carboplatin (CBDCA), docetaxel (DOC) and laser treatment was performed for the T2 cases. The 5-year survival rates of the T1 and T2 cases were 94.7% and 94.8%, respectively. The 5-year laryngeal preservation rates of the T1 and T2 cases were 97.1% and 72.3%, respectively. The 5-year survival rates of the glottic cancer and supraglottic cancer cases were 96.7% and 87.0% and the 5-year laryngeal preservation rates of these cases were 97.1% and 57.2%, respectively. Particularly in T2 supraglottic laryngeal cancer, the laryngeal preservation rate is not improved even with concurrent chemoradiotherapy by CBDCA and FAR therapy. To improve the laryngeal preservation rate in T2 supraglottic laryngeal cancer, it is necessary to consider concurrent chemoradiotherapy by DOC or hyperfractionation. (author)

    Creation of a tunneled mucosal shunt between the trachea and pharynx that is controlled by remaining intrinsic laryngeal musculature with its nerve supply is an acceptable voice restoration procedure for advanced T3 and T4 laryngeal cancer. Such a tunnel will allow unilateral direction of air from lung to pharynx during phonation and will prevent aspiration since deglutition is a vagal mediated response which will induce contraction of tubed laryngeal musculature preventing aspiration. We previously reported our preliminary experience with the technique and we adopted the voice restoration approach based on the concept of the near total laryngectomy thereafter. Methods: Forty five patients with histologically proven squamous cell carcinoma of the larynx were included in this study (between January 1998 and February 2001). They were 42 males and 3 females with a mean age of 52.6 years. Criteria for selection were a normal vocal process and arytenoid cartilage on the opposite side of the lesion as evidenced by endoscopy and CT scan with no major sub glottic extension. In two patients supraglottic laryngectomy was carried out and in four other patients, complete tumor extirpation necessitated total laryngectomy. Accordingly, near total laryngectomy was carried out in the remaining 39 patients. Following a near total laryngectomy, where all laryngeal mucosa and cartilages are resected sparing the contralateral arytenoid cartilage with the overlying mucosa and surrounding musculature, the shunt was created by tubing the remaining mucosa with augmentation by pyroform sinus mucosa if necessary. The resulting tube was fashioned over 14 FG catheter for diameter control only and the remaining muscles were sutured over the tube. A permanent tracheostomy was established. Voice training was started postoperatively following resumption of oral feeding. Results: Only one patient died in the immediate postoperative period due to massive myocardial infarction. One patient developed

    Laryngeal cancer is the commonest carcinoma of the head and neck region with Squamous-cell carcinomas (SCC) in 90 % of cases (Birchall Met al 2008) The incidence of laryngeal cancer was relatively about 160,000 new cases per year. The disease predominantly affects men; about 2.4% of all cancer cases and 2.1% of all cancer deaths worldwide ,also in United States in 2012 the Es)mated new cases is 12,360 and deaths from laryngeal cancer is 3,650. The majority of patients with SCC of larynx present with locally advanced (LA) disease.(American Cancer Society, 2012) The incidence of laryngeal cancer in the Kasr El-Aini Center of Radiation Oncology and Nuclear Medicine (NEMROCK), Faculty of Medicine, Cairo University from year 2005 - 2008 is 3.1%per year. Advanced laryngeal cancer is generally considered as the disease in stages III and IV based on the primary tumor extension and/or the presence of metastatic lymph node(s) in the neck and it accounts for roughly 40% to 50% of patients with laryngeal cancer (Chen AY, et al 2006). From the second half of the 20th century total laryngectomy combined with a neck dissection was considered a treatment of choice for advanced laryngeal cancer (Genden EM et al, 2007). In most institutions, postoperative radiotherapy as adjuvant treatment following ablative surgery with radiation doses up to 60-66 Gy has also become the standard approach for patients with stage III-IV laryngeal cancer (Corvo R , 2007). However, the treatment of advanced laryngeal cancer seams to be a permanent challenge, but the management of patients with advanced laryngeal cancer has become more complex as other modalities including induction chemotherapy followed by radiotherapy or concurrent chemo-radiotherapy have evolved with the goal of preserving the larynx and reserved total laryngectomy as a salvage procedure for cases with less than 50% response to induction chemotherapy or in those who have persistent disease following concurrent chemo

    From 1974 through 1992, 37 previously untreated patients with T3 laryngeal cancer (supraglottic 15, glottic 22) were treated with initial radical radiotherapy and surgery for salvage. Two-year local control rate with radiotherapy alone, ultimate voice preservation rate, and ultimate local control rate for T3 supraglottic cancer were 33%, 33%, and 60%, respectively. Corresponding figures for T3 glottic cancer were 32%, 23%, and 77%, respecitvely. Five-year cause-specific survival rate for T3 supraglottic cancer and glottic cancer were 47% and 77%, respectively. In T3 supraglottic cancer, none of the 4 patients with subglottic tumor extension attained local control by radiotherapy alone, and local-regional recurrence-free time were significantly shorter in patients with subglottic tumor extension or tracheostomy before radiotherapy. There were no serious late complications such as chondronecrosis, rupture of carotid artery attributed to radical radiotherapy, while 3 patients had severe laryngeal edema requiring total laryngectomy.

    Multispiral computed tomography (MSCT) with intravenous bolus contrasting is a currently available method for radiodiagnosis of laryngeal cancer. MSCT is of much higher informative value in estimating the extent of a tumorous lesion than the traditional radiodiagnostic techniques: linear tomography, lateral X-ray study, roentgenoscopy and roentgenography of the laryngopharynx and esophagus with barium meal.

    We retrospectively analyzed 71 consecutive cases of early laryngeal cancer (stage I or II) that had undergone primary treatment in our department between 1999 and 2004. There were 68 males and 3 females, and their ages ranged from 40 to 85 years of age (average; 67.7 years). Eight patients had the supraglottic type, 61 had the glottic type, and 2 had the subglottic type. Chemoradiotherapy was performed as the primary treatment except in the patients with glottic T1a cancer, who received radiotherapy alone. The 5-year survival rates was 91.1% for glottic cancer (T1a: 100%, T1b: 92.3%, T2: 85.8%) and 75.0% for supraglottic cancer. The local control rate of glottic cancer was 79.6% (T1a: 80.0%, T1b: 74.0%, T2: 85.2%), and significantly higher than that of supraglottic cancer (56.2%, p<0.05). The laryngeal preservation rate was 84.4% in glottic cancer (T1a: 100%, T1b: 76.9%, T2: 77.5%) and 58.3% in supraglottic cancer, and the difference between T1a and T2 glottic cancer was significant (p<0.05). Local recurrence and cervical lymph node metastasis were seen in 9 patients and 6 patients, respectively. Distant metastasis occurred in 4 patients, all of whom had the glottic type. Four patients died of their disease, and distant metastasis was the major cause of death in 3 of them. These results indicate that additional treatment should be performed in cases in which radiotherapy/chemoradiotherapy is ineffective and that both in the early stages glottic and supraglottic cancers can be successfully treated by radiotherapy/chemoradiotherapy. The results also suggested that the survival of patients with early laryngeal cancer depends on whether they develop distant metastasis. Introduction of adjuvant chemotherapy to improve their prognosis remains to be assessed. (author)

    Laryngeal cancer is the most common malignant tumor in the head and neck region. Because early detection and treatment are possible, outcomes are relatively good. Many studies have reported on the treatment of laryngeal cancer. Different hospitals have used generally similar treatment regimens. However, factors such as laryngeal preservation and the treatment of choice for patients with T2 laryngeal cancer still differ among hospitals. Survival rates can be increased depending on treatment, sometimes at the cost of losing voice functions that could have been preserved. In our department, we have emphasized curative treatment and the preservation of organs and functions. We have mainly used chemoradiotherapy concurrently with S-1 and nedaplatin for the treatment of T2 laryngeal cancer. We studied 27 patients (23 men and 4 women) with T2 laryngeal cancer, who received first-line therapy in our department from April 2005 through March 2010. Their mean age was 64.1 years (range, 42 to 80). The mean follow-up period was 30.6 months (range, 2 to 60 months). The tumor-node-metastasis classification was T2N0M0 in 24 patients, T2N1M0 in 1, and T2N2bM0 in 2.In our department, the disease-specific survival rate was 96.3%. The complete response rate was 88.9%, and the laryngeal preservation rate was 92.6%. (author)

    We conducted a case-control study to investigate the effect of diet on laryngeal carcinogenesis. Our study population was made up of 140 participants-70 patients with laryngeal cancer (LC) and 70 controls with a non-neoplastic condition that was unrelated to diet, smoking, or alcohol. A food-frequency questionnaire determined the mean consumption of 113 different items during the 3 years prior to symptom onset. Total energy intake and cooking mode were also noted. The relative risk, odds ratio (OR), and 95% confidence interval (CI) were estimated by multiple logistic regression analysis. We found that the total energy intake was significantly higher in the LC group (p pastas) was also higher among the LC patients (p = 0.043), with logistic regression analysis showing that their negative effect was possibly associated with the sauces and dressings that traditionally accompany pasta dishes (p = 0.006; OR: 4.78). Conversely, a higher consumption of dairy products was found in controls (p < 0.05); logistic regression analysis showed that calcium appeared to be protective at the micronutrient level (p < 0.001; OR: 0.27). We found no difference in the overall consumption of fruits and vegetables between the LC patients and controls; however, the LC patients did have a greater consumption of cooked tomatoes and cooked root vegetables (p = 0.039 for both), and the controls had more consumption of leeks (p = 0.042) and, among controls younger than 65 years, cooked beans (p = 0.037). Lemon (p = 0.037), squeezed fruit juice (p = 0.032), and watermelon (p = 0.018) were also more frequently consumed by the controls. Other differences at the micronutrient level included greater consumption by the LC patients of retinol (p = 0.044), polyunsaturated fats (p = 0.041), and linoleic acid (p = 0.008); LC patients younger than 65 years also had greater intake of riboflavin (p = 0.045). We conclude that the differences in dietary consumption patterns between LC patients and controls

    Head and neck cancer patients commonly suffer from severe malnutrition at the time of tentative diagnosis. Percutaneous Endoscopic Gastrostomy [PEG] feeding is now considered as an efficient tool to reduce nutritional deterioration alongside concurrent treatment. We undertook the challenge to retrospectively evaluate the impact of a commercial, disease-specific, feeding formula [Supportan, Fresenius Kabi, Hellas] versus blenderized family food on nutritional outcome. This is a retrospective analysis of prospectively collected nutritional and anthropometric data at the time of PEG placement, at the 8th week [after treatment termination] and at 8 months [6mo of recovery from treatment]. All patients were prescribed a commercial feeding formula. The final dataset included 212 patients: 112 received the commercial formula, 69 voluntarily decided to switch into blenderized-tube-feeding, and 31 were prescribed to receive a home-made formula of standard ingredients. The commercial formula seemed to help patients to fight the catabolism of concurrent treatment, since, at the 8mo assessment, both Body Mass index and Fat Free Mass had almost recovered to the values at the time of first diagnosis. Neither group on blenderized or home-made formulas exhibited nutritional improvement, but experienced a significant deterioration throughout the study period, with the home-made formula group being the worst. These findings clearly indicate that home-made and blenderized foods do not adequately support the nutritional requirements of patients with HNC scheduled to receive concurrent CRT treatment.

    The standard treatment for advanced laryngeal cancer has been shifting from total laryngectomy to various organ preservation therapies such as subtotal laryngectomy and chemoradiotherapy. Robbins showed remarkable results with RADPLAT, the superselective intra-arterial infusion of supradose cisplatin (150 mg/m 2 ), against advanced head and neck cancer. However, the volume of laryngeal cancer is smaller than those of the other sites of head and neck cancers, and so a swaller less dose of cisplatin could save advanced laryngeal cancer patients. It may be reasonable to treat these subtypes of laryngeal cancer with a different modality. Thirty-five patients with laryngeal cancer were treated with tri-weekly intra-arterial infusion of cisplatin (100 mg/body). A 200 times molar excessive amount of sodium thiosulfate was intravenously infused to reduce the toxicity of cisplatin. Ten of 16 patients with glottic cancer and 10 of 19 patients with supraglottic cancer were followed for more than 2 years. Larynx preservation rate of glottic and supraglottic cancer was 80% and 70%, and progression-free survival rate was 80% and 50%, respectively. Grade III and IV toxic events were less frequent than with RADPLAT or systemic administration of a similar dose of cisplatin. Glottic and supraglottic cancers show different clinical behaviors. Our protocol with less cisplatin than RADPLAT is especially effective for glottic cancer. (author)

    Fifty-nine cases of laryngeal cancer treated by radiotherapy at the National Cancer Center Hospital between 1962 and 1990 were analyzed retrospectively. All the patients were less than 50 years old. The median total dose of the radiation delivered to the primary tumor site was 70 Gy. The overall 5-yr survival rate and 5-yr local control rate were 88% and 72%, respectively. Five (8.5%) of the 59 patients developed late recurrence more than five yr after initial treatment, but subsequent salvage operations were successful for disease control; three patients had T1 glottic cancer, one had T2-3 glottic cancer and one had T3N1 supraglottic cancer. Since the local control rate and the 5-yr survival rate after radiotherapy are satisfactory, radiotherapy, which allows both functional and esthetic conservation, has an important role in the treatment of laryngeal cancer in adults under 50 yr of age.

    Amyloidosis is a slowly progressive, benign disease that is characterized by the extracellular deposition of fibrillar proteins in many different tissues and organs throughout the body. Primary amyloidosis can be subdivided into the systemic and localized forms. The localized form is less common than the systemic form and the larynx is the most frequently affected site. The importance of laryngeal amyloidosis lies in its possible confusion with glottic cancer because of the clinical feature.

Laryngeal videostroboscopy (LVS has not been routinely used to assess post-radiotherapy (RT voice changes. We hypothesized that LVS would demonstrate improvement in laryngeal function after definitive RT for early-stage glottic cancer.Study designBlinded retrospective review of perceptual voice and stroboscopic parameters for patients with early glottic cancer and controls.SettingHigh-volume, single-institution academic medical center.Subjects and methodsFifteen patients underwent RT for Tis-T2N0M0 glottic cancer and were evaluated with serial LVS exams pre- and post-RT. Stroboscopic assessment included six parameters: vocal fold (VF vibration, VF mobility, erythema/edema, supraglottic compression, glottic closure, and secretions. Grade, roughness, breathiness, asthenia, strain (GRBAS voice perceptual scale was graded in tandem with LVS score. Assessments were grouped by time interval from RT: pre-RT, 0–4, 4–12, and >12 months post-RT.Results60 LVS exams and corresponding GRBAS assessments were reviewed. There were significant improvements in ipsilateral VF motion (P = 0.03 and vibration (P = 0.001 and significant worsening in contralateral VF motion (P < 0.001 and vibration (P = 0.008 at >12 months post-RT. Glottic closure significantly worsened, most prominent >12 months post-RT (P = 0.01. Composite GRBAS scores were significantly improved across all post-RT intervals.ConclusionLVS proved to be a robust tool for assessing pre- and post-RT laryngeal function. We observed post-RT improvement in ipsilateral VF function, a decline in contralateral VF function, and decreased glottic closure. These results demonstrate that LVS can detect meaningful changes in VF and glottic function and support its use for post-RT evaluation of glottic cancer patients.

    Four hundred and eighty six previously untreated patients with cancer of the larynx were radically irradiated at the Institute of Oncology in Krakow in the years 1951--1966. Five-year cure rate without cancer symptoms after irradiation as the only treatment was 43% or 209 of 486 cases, and after surgery for recurrent cancer there were in addition, 55 survivors (11%). Dosage schemes of /sup 60/Co therapy for laryngeal tumor have been devised giving a dose of 6,000 rads per 24 fractions in 5 weeks. When irradiating the larynx together with cervical lymph nodes the dose of 6,000 rads was given during 6 to 7 weeks plus further irradiation at a lower dose if necessary. Two techniques of /sup 60/Co irradiation of typical cases of laryngeal cancer are described.

    Full Text Available Abstract Background Aim of this longitudinal study was to investigate the sensitivity to change of the Swedish Self Evaluation of Communication Experiences after Laryngeal Cancer questionnaire (the S-SECEL, addressing communication dysfunction in patients treated for laryngeal cancer. Previous studies have highlighted the need for more specific questionnaires for this purpose. Methods 100 patients with Tis-T4 laryngeal cancer were included prior to treatment onset. Patients answered four questionnaires at six occasions during one year; the S-SECEL, the European Organisation for Research and Treatment of Cancer (EORTC Core Quality of Life Core Questionnaire (QLQ-C30 supplemented by the Head and Neck cancer module (QLQ-H&N35 and the Hospital Anxiety and Depression (HAD scale. In addition, performance status was assessed. Differences within groups were tested with the Wilcoxon paired signed ranks test and between-group analyses were carried out using the Mann-Whitney U test. Magnitude of group differences was analyzed by means of effect sizes. Results The S-SECEL was well accepted with a response rate of 76%. Communication dysfunction increased at 1 month, followed by a continuous decrease throughout the year. Changes were statistically significant at most measurement, demonstrating the sensitivity of the S-SECEL to changes in communication over time. The S-SECEL and the EORTC QLQ-C30 with the QLQ-H&N35 demonstrated similar results; however the S-SECEL was more sensitive regarding communication dysfunction. The largest changes were found in the most diagnose specific items concerning voice and speech. Conclusion The S-SECEL was investigated in the largest Scandinavian longitudinal study concerning health-related quality of life (HRQL in laryngeal cancer patients. The questionnaire was responsive to change and showed convergent results when compared to established HRQL questionnaires. Our findings also indicate that the S-SECEL could be a more

    Purpose: To determine the safety and radiation-enhancing effect of sodium glycididazole in laryngeal squamous cell carcinoma (stage T3-4,N0-3,M0) with conventional radiotherapy. Patients and methods: Patients with locoregional advanced laryngeal cancer (stage T3-4,N0-3,M0) were included: group 1(control, n = 30)were not administered of sodium glycididazole; group 2 (test, n = 30) received sodium glycididazole at a dose of 700 mg/m2 intravenous infusion 30 minutes before radiotherapy three times a week. Surrogate end-points of efficacy were tumor and nodal size. Safety parameters were vomiting, nausea, mucositis, laryngeal edema, esophagus and skin reaction, dysphagia, dyspnea, neurological deficit. Patients were evaluated weekly during treatment for 7 weeks and thereafter monthly for 3 months. Results: In the test, the overall response rate was 88.89% (95% CI, 71.00-97.00%) at 7 weeks and 92.59% (95% CI, 76.00 to 99.00%) at 1 month of follow-up. In the control, the overall response rate was 62.5% (95% CI, 41.00 to 81.00%) at 7 weeks and 58.33% (95% CI, 37.00 to 78.00%) at 1 month of follow-up. The short-term locoregional response rate was better in the test group at 7 weeks (p = 0.027) and at 1 month (p = 0.005) of follow-up. The test group had significantly more nausea and vomiting in weeks 1 (p = 0.047), 2 (p = 0.007), and 3 (p = 0.01) of treatment. Conclusions: The study indicates sodium glycididazole is an effective radiation-enhancing agent that improves short-term locoregional control and is well tolerated in patients with loco regionally advanced laryngeal cancer.

  18. The percentage of iNKT cells among other immune cells at various clinical stages of laryngeal cancer

    Directory of Open Access Journals (Sweden)

    Janusz Klatka

    2016-04-01

    Full Text Available Introduction: Invariant natural killer T (iNKT cells constitute a small population of immune cells that share functional and phenotypic characteristics of T lymphocytes and NK cells. Due to their involvement in specific and non-specific immune responses, iNKT cells may represent an important component of antitumor and anti-infectious immunity. Material and methods: Using flow cytometry, we analyzed the percentages of iNKT cells as well as T and B lymphocytes in peripheral blood of 50 laryngeal cancer patients at various clinical stages in comparison to healthy controls (n=15. Moreover, we determined the expression of CD25, CD69 and CD95 antigens on T lymphocytes.Results: The percentage of CD4+/CD3+ T lymphocytes in the controls was higher than in laryngeal cancer patients, both with early and late stages of the disease. The percentage of CD8+/CD3+ T lymphocytes in healthy controls was lower than in patients with early and late clinical stages of laryngeal cancer. Patients with advanced laryngeal cancer showed a lower percentage of iNKT cells and higher frequencies of T regulatory cells (Tregs than the controls. Advanced clinical stages of laryngeal cancer are associated with impaired activation of lymphocytes.Conclusions: Our study confirmed that laryngeal cancer cells exert a strong suppressor effect on the immune system of the host. This is reflected by a decrease in the percentage of iNKT cells that are capable of cancer cell elimination, and a concomitant increase in the percentage of Tregs. However, further studies are needed in order to explain the underlying mechanisms of immunosuppression and understand interactions between immune and cancer cells.

Pt. characteristics - 88% men, 12% women, age: 29-82 years, stages: T1-20%, T2 -34%, T3 -30%, T4 -16%, lymph node metastases: 27%. Complete response to treatment (CR) - 71% of cases. Loco-regional control after 2 years 52% (T1-T2 - 64%, T3 - T4 - 40%). Early reactions: pain on swallowing, confluent mucositis and moist skin reaction in 69%, 48% and 41 % of cases, respectively. Serious late complications - 19 patients. In a majority of these cases several forms of serious damage were observed. Patients with advanced disease (T3-T4) present a two times higher death risk as compared to patients in earlier stages of the disease (T1-T2). Patients with cervical node metastases also present a two times higher death risk as compared to N0 cases. Patients with performance status 1 or more had a respectively three or four times higher death risk than patients with performance status - 0. No significant influence of sex, histological differentiation, site, hemoglobin level and cigarette smoking, pulmonary and coronary diseases on treatment outcome has been found. The survival curves come down steeply three and more years after treatment completion due to causes other than local failure. The limited number of serious early and late reactions suggests the possibility of a total dose increase. (author)

    The authors analyse a retrospective series of 90 consecutive patients (pts) affected with locally advanced laryngeal carcinoma (T3-4, N0-3 - TNM, UICC 1978) who were radically irradiated from November 1979 to December 1986 at the Radiotherapy Department of the General Hospital of Varese. All the patients were treated with 60 Co and two opposed parallel lateral fields and progressive shrinkage: 66 conventional fractionation (2 Gy once a day, 5 times a week), 24 with an accelerated hyperfractionated regimen (1.5 Gy twice a day, 5 times a week). The median total dose delivered to the tumor and clinically involved nodes was 64 Gy (1678 reu, CRE). Median follow-up was 21 months (range: 3-113). The 5-year overall survival (Kaplan-Meier) was 40.5%. The 5-year disease-free survival, for 47 patients in complete remission at the end of radiotherapy, was 51.9% after irradiation alone and 56.7% with salvage surgery. There were no statistically significant differences in survival according to local spread (T3 vs T4), nodal status (N0 vs N1-3) and dose fractionation regimen (conventional vs accelerated hyper-fractionated). Isoeffect (CRE) values above 1751 reu obtained a 3-year loco-regional control rate was 33.3%. Relevant late sequelae were not observed. Our findings suggest that primary radiotherapy with salvage surgery in reserve could be considered as an effective choice for locally advanced laryngeal carcinoma, at least in selected groups of patients

    It has recently been suggested that reactive oxides produced by inflammation may result in cell injury, leading to mucositis and dermatitis. Azelastine hydrochloride suppresses the production of cytokines and reactive oxygen species, and some reports have documented its effectiveness in treating radiation mucositis and dermatitis. Therefore, we investigated the effectiveness of azelastine hydrochloride in preventing these diseases during radiation therapy for laryngeal cancer. Subjects were patients with laryngeal carcinomas who received curative radiation therapy. A close of 1 mg of azelastine hydrochloride was administered orally twice a day, from the start of the radiation therapy until one-four weeks after the completion of therapy. Chronological changes in the pharyngo-laryngeal cavity and the neck skin of the patients who received azelastine hydrochloride were compared with those of patients who did not. In the patients who received the azelastine hydrochloride, the onset of pharyngo-laryngeal mucositis and dermatitis was suppressed; symptoms were relieved earlier and were not exacerbated. No severe side effects were observed, and the effectiveness of the radiation therapy was not affected. The administration of azelastine hydrochloride concurrently with radiation therapy for laryngeal cancer suppressed the onset of pharyngo-laryngeal mucositis and dermatitis and alleviated the severity of these diseases.

    This study aimed to clarify the local immune status in the larynx in the presence of infection or carcinogenesis associated with human papilloma virus. Cytological samples (for human papilloma virus detection) and laryngeal secretions (for immunoglobulin assessment) were obtained from 31 patients with laryngeal disease, during microscopic laryngeal surgery. On histological examination, 12 patients had squamous cell carcinoma, four had laryngeal papilloma and 15 had other benign laryngeal disease. Cytological samples were tested for human papilloma virus DNA using the Hybrid Capture 2 assay. High risk human papilloma virus DNA was detected in 25 per cent of patients (three of 12) with laryngeal cancer. Low risk human papilloma virus DNA was detected only in three laryngeal papilloma patients. The mean laryngeal secretion concentrations of immunoglobulins M, G and A and secretory immunoglobulin A in human papilloma virus DNA positive patients were more than twice those in human papilloma virus DNA negative patients. A statistically significant difference was observed between the secretory immunoglobulin A concentrations in the two groups. Patients with laryngeal cancer had higher laryngeal secretion concentrations of each immunoglobulin type, compared with patients with benign laryngeal disease. The study assessed the mean laryngeal secretion concentrations of each immunoglobulin type in the 12 laryngeal cancer patients, comparing human papilloma virus DNA positive patients (n = 3) and human papilloma virus DNA negative patients (n = 9); the mean concentrations of immunoglobulins M, G and A and secretory immunoglobulin A tended to be greater in human papilloma virus DNA positive cancer patients, compared with human papilloma virus DNA negative cancer patients. These results suggest that the local laryngeal immune response is activated by infection or carcinogenesis due to human papilloma virus. The findings strongly suggest that secretory IgA has inhibitory activity

    Patients are increasingly using the internet to access health-related information. The purpose of this study was to assess the readability and quality of laryngeal cancer-related websites. Patient education materials were identified by performing an internet search using 3 search engines. Readability was assessed using Flesch Reading Ease Score (FRES), Flesch-Kincaid Grade Level (FKGL), and Gunning Fog Index (GFI). The DISCERN instrument was utilized to assess quality of health information. A total of 54 websites were included in the analysis. The mean readability scores were as follows: FRES, 48.2 (95% confidence interval [CI] = 44.8-51.6); FKGL, 10.9 (95% CI = 10.3-11.5); and GFI, 13.8 (95% CI = 11.3-16.3). These scores suggest that, on average, online information about patients with laryngeal cancer is written at an advanced level. The mean DISCERN score was 49.8 (95% CI = 45.4-54.2), suggesting that online information is of variable quality. Our study suggests much of the laryngeal cancer information available online is of suboptimal quality and written at a level too difficult for the average adult to read comfortably. © 2015 Wiley Periodicals, Inc.

    Full Text Available BACKGROUND: MicroRNA (miRNA is an emerging subclass of small non-coding RNAs that regulates gene expression and has a pivotal role for many physiological processes including cancer development. Recent reports revealed the role of miRNAs as ideal biomarkers and therapeutic targets due to their tissue- or disease-specific nature. Head and neck cancer (HNC is a major cause of cancer-related mortality and morbidity, and laryngeal cancer has the highest incidence in it. However, the molecular mechanisms involved in laryngeal cancer development remain to be known and highly sensitive biomarkers and novel promising therapy is necessary. METHODOLOGY/PRINCIPAL FINDINGS: To explore laryngeal cancer-specific miRNAs, RNA from 5 laryngeal surgical specimens including cancer and non-cancer tissues were hybridized to microarray carrying 723 human miRNAs. The resultant differentially expressed miRNAs were further tested by using quantitative real time PCR (qRT-PCR on 43 laryngeal tissue samples including cancers, noncancerous counterparts, benign diseases and precancerous dysplasias. Significant expressional differences between matched pairs were reproduced in miR-133b, miR-455-5p, and miR-196a, among which miR-196a being the most promising cancer biomarker as validated by qRT-PCR analyses on additional 84 tissue samples. Deep sequencing analysis revealed both quantitative and qualitative deviation of miR-196a isomiR expression in laryngeal cancer. In situ hybridization confirmed laryngeal cancer-specific expression of miR-196a in both cancer and cancer stroma cells. Finally, inhibition of miR-196a counteracted cancer cell proliferation in both laryngeal cancer-derived cells and mouse xenograft model. CONCLUSIONS/SIGNIFICANCE: Our study provided the possibilities that miR-196a might be very useful in diagnosing and treating laryngeal cancer.

    By collecting and analyzing the laryngeal cancer related genes and the miRNAs, to build a comprehensive laryngeal cancer-related gene database, which differs from the current biological information database with complex and clumsy structure and focuses on the theme of gene and miRNA, and it could make the research and teaching more convenient and efficient. Based on the B/S architecture, using Apache as a Web server, MySQL as coding language of database design and PHP as coding language of web design, a comprehensive database for laryngeal cancer-related genes was established, providing with the gene tables, protein tables, miRNA tables and clinical information tables of the patients with laryngeal cancer. The established database containsed 207 laryngeal cancer related genes, 243 proteins, 26 miRNAs, and their particular information such as mutations, methylations, diversified expressions, and the empirical references of laryngeal cancer relevant molecules. The database could be accessed and operated via the Internet, by which browsing and retrieval of the information were performed. The database were maintained and updated regularly. The database for laryngeal cancer related genes is resource-integrated and user-friendly, providing a genetic information query tool for the study of laryngeal cancer.

    Background: Recent studies have shown that BCCIP (BRCA2 and CDKN1A interacting protein) is essential for maintaining the transactivation activity of wild type p53. We analyzed the expression of BCCIP and p53 in a cohort of laryngeal cancer treated with radiotherapy and assessed whether BCCIP and p53, alone or in combination, would correlate with local control and overall survival. Methods: One hundred twenty-three patients treated between 1975 and 2000 for early stage (stages I and II) squamous cell carcinoma of the larynx were included in the study. Treatment consisted of radiation therapy (RT) with standard fields and fractionation to a median dose of 66 Gy. Tissue was collected from pre-RT biopsies and constructed in a tissue microarray, and BCCIP expression and p53 expression were determined using immunohistochemistry. Results: Loss of expression of BCCIP in combination with normal p53 (negative p53 staining) was associated with local recurrence (RR 2.04; 95% CI 0.99-4.56, p = 0.05) and poor overall survival (RR 2.09; 95% CI 1.21-4.00, p = 0.008) compared to patients who did express BCCIP. Expression of BCCIP or p53 alone was not found to be independently associated with benefits in local control or overall survival. Conclusions: This study provides clinical evidence that BCCIP contributes to outcomes in patients with laryngeal cancer treated with RT. This benefit may be a result of increased radiosensitivity in patients who have functional BCCIP and p53. These data may be used to identify sub-groups of laryngeal cancer patients who are more likely to be cured with radiotherapy

    Purpose: To determine quality of life (QOL) and health utility in irradiated laryngeal cancer survivors. Materials and Methods: Over 6 months, consecutive follow-up patients at a comprehensive cancer centre completed the QOL questionnaire FACT-H and N and the time trade-off (TTO) utility instrument. Results: Inclusion criteria were met by 339 patients, of whom 269 were eligible, 245 were approached, and 120 agreed to participate. Most participants were men (83%) who had received radiotherapy (97%) for Stage I disease (53%) of the glottis (75%); 7% had undergone total laryngectomy. Participants differed from nonparticipants only in being younger (mean age, 65 vs. 68 years, p = 0.0049) and having higher performance status (Karnofsky 88 vs. 84, p = 0.0012). The average scores for FACT-H and N and the TTO were 124/144 (SD, 14) and 0.90/1.0 (SD, 0.16) respectively. FACT-H and N score was more highly correlated with Karnofsky score (r = 0.43, p = 0.001) than with the TTO (r = 0.29, p = 0.002). Gender predicted QOL (means: M = 125, F 118), while natural speech, no relapses, and more time since initial treatment predicted higher utility. Conclusion: The QOL of irradiated laryngeal cancer survivors was reasonably high and independent of initial disease variables. The QOL questionnaire correlated more strongly with performance status than with utility, suggesting that QOL and utility measures may be perceived differently by patients

    Radiation therapy in those with head and neck malignancies often triggers painful mucositis poorly controlled by nonsteroidal antiinflammatory drugs (NSAIDs). To better understand how radiation-induced pain develops over time, we studied the numerical rating scale (NRS 0-5) pain scores from 32 persons undergoing radiation therapy of 60-72 Gy for newly diagnosed laryngeal cancer. The degree of mucositis was evaluated using Common Terminology Criteria for Adverse Events version3.0 (CTCAE v3.0). We divided the 32 into a conventional fractionation (CF) group of 14 and a hyperfractionation (HF) group of 18, and further divided laryngeal cancer into a small-field group of 23 and a large-field group of 9. The mucositis pain course was similar in CF and HF, but mucositis pain was severer in the HF group, which also required more NSAIDs. Those in the large-field group had severer pain and mucositis and required more NSAIDs than those in the small-field group. We therefore concluded that small/large-field radiation therapy, rather fractionation type, was related to the incidence of radiation-induced mucositis pain. (author)

    Full Text Available Squamous cell carcinoma of head and neck (SCCHN is often asymptomatic until it reaches the advanced stage. Currently, there are no available markers that can accurately predict the risk of progression of epithelial dysplasia to squamous cell carcinoma. The purpose of the study was to evaluate the feasibility of using the level of adenylyl cyclase-associated protein 1 (CAP-1 in the blood serum to identify groups of increased risk of cancer in patients with chronic laryngeal and hypopharyngeal hyperplasia associated with epithelial dysplasia. Material and methods. The blood serums from 45 patients with SCCHN (T1–4N0–3M0, 12 patients  with chronic inflammatory laryngeal and hypopharyngeal diseases and 15 heath subjects were examined. The blood analysis was performed using the CAP1 ELISA kit (Cusabio on the Biochrom Anthos 2020 Microplate IEA Reader. Results. The serum level of САР1 was higher by 75 % in patients with SCCHN (Т1N0M0 than in patients with chronic hyperplastic laryngitis. Moreover, differences in the serum level of САР1 were observed between healthy subjects and patients with chronic laryngeal hyperplasia. In SCCHN patients with regional metastases, CAP1 concentration in the blood serum was 2 times higher compared to that observed in SCCHN patients without regional metastases (p≤0.01. Conclusion. The study results showed the feasibility of using the level of CAP1 for distinguishing patients with chronic hyperplastic laryngitis from those with laryngeal cancer, as well as for early detection of SCCHN and the development of new method for prediction of disease.

    A case-control study of 47 laryngeal cancers in males of three counties of Washington State was conducted. Personal interview was used to obtain information on smoking, alcohol use, exposure to asbestos, and other substances, and x-rays of the head and neck area. Smoking and alcohol consumption were found to increase risk of laryngeal cancer independently, with a clear dose-response relationship. Neither asbestos exposure nor exposure to other substances was found to significantly increase the risk of laryngeal cancer, although the relative risk with asbestos exposure was 1.75. Lifetime history of exposure to dental x-rays on five or more occasions was associated with significantly increased risk of laryngeal cancer among heavy smokers but not among light smokers. The importance of tobacco and alcohol in the epidemiology of laryngeal cancer was re-affirmed, the importance of asbestos exposure was brought into question, and a possible relationship of laryngeal cancer with exposure to dental x-rays among heavy smokers was demonstrated

    Retrospective chart review. To determine the efficacy of adjuvant cryotherapy in the treatment of early glottic cancer and laryngeal papillomatosis. The use of cryotherapy in conjunction with traditional modalities has recently been proposed to improve voice outcomes in patients with early laryngeal cancer as compared to pretreatment conditions. This study investigates its utility in improving oncological outcomes and decreasing recurrences of laryngeal papillomatosis. Patients with either early glottic cancer or laryngeal papillomatosis that received cryotherapy as part of their surgical regimen were investigated. All patients were seen at a large tertiary care center within a 10-year window. Demographic data were collected and all postoperative notes were reviewed. Recurrences of the laryngeal cancer were noted, as was the duration of time between successive papillomatosis operations. The charts of 54 glottic cancer and 29 papillomatosis patients that received cryotherapy were reviewed. One patient from the papillomatosis cohort was excluded from statistical analysis due to lack of follow-up. Overall, 16 (30%) of the laryngeal cancer patient experienced a malignant recurrence. The overall 5-year survival of these patients was 98% and the 5-year disease-free survival was 74%. The use of adjuvant cryotherapy in the treatment of laryngeal papillomatosis extended the duration of time between surgeries by an average of 79 days (P=.23). The use of adjuvant cryotherapy in the treatment of early glottic cancer does not improve the rate of carcinoma recurrences. Additionally, cryotherapy does not result in a statistically significant increase in the duration of disease-free period for laryngeal papillomatosis patients, although the observed increase may be clinically important. © The Author(s) 2015.

    This article presents a review of the medical literature published between 1994 and 2014 with the use of the PubMed database concerning quality-of-life instruments for head and neck cancer patients used to assess general well-being of patients with laryngeal cancer. The PubMed database was searched for articles containing the keywords "quality of life", "laryngeal neoplasm" and "questionnaires". The resulting articles were reviewed and analyzed. After the identification of questionnaires, an additional search was performed. The articles and questionnaires were described and analyzed. In 43 articles, the authors used questionnaires specific to the head and neck regions in order to assess the quality of life in patients with laryngeal cancer. Four different questionnaires were identified. The European Organization for Research and Treatment of Cancer (EORTC) questionnaire is most commonly used to assess the quality of life in patients with laryngeal cancer. Questionnaires are generally used in order to select from a range of different treatment methods. There are a few head and neck cancer-related quality-of-life instruments which are widely used to assess the quality of life in patients with laryngeal cancer, but they are not dedicated to that region of the body. Today, there is much more attention paid to the quality of life; therefore, there is a real need to develop specific scales for different types of cancer.

    There are many methods of treating laryngeal cancers: definitive irradiation with or without concurrent chemotherapy, endoscopic laser surgery, partial surgery techniques, and total laryngectomy. Few studies have been reported on vocal function and quality of life of patients after the definitive treatment for laryngeal cancer, using single voice related QOL measures. The aim of this study was to examine voice related QOL in patients treated with various modalities using a Voice-Related Quality of Life (V-RQOL) questionnaire as well as Voice Handicap Index-10 (VHI-10) questionnaire. Between August 2006 and May 2007, survey data on voice utilizing the V-RQOL and VHI-10 were obtained from a total of 130 patients who had received definitive treatment for laryngeal cancers with follow-up at the Hokkaido University Hospital, and who were alive with no evidence of malignancy at the time of survey. Mean V-RQOL scores of the patients who received radiation therapy (n=63), chemoradiotherapy (n=29), laser resection (n=14) and total laryngectomy (n=27) as the final treatment for laryngeal cancer were 92.6, 92.9, 85.5, and 68.4, respectively. Mean VHI-10 values were 2.87, 2.34, 5.43, and 11.26. Such measures of quality of life are important endpoints to help judge the overall effectiveness of treatment options for laryngeal cancers.

    Swallowing is a complex neuromuscular process that requires anatomical indemnity and an adequate coordination of several organs. Laryngeal cancer treatment may cause swallowing disorders. Traditionally, a high frequency of this type of disorder after surgery has been reported, but no actual data concerning its incidence in patients undergoing radiotherapy for early laryngeal cancer has been published. Aim. To compare swallowing disorders frequency posterior to treatment in early laryngeal cancer patients. Material and Method. Two groups of early laryngeal cancer patients were transversally studied, one treated with vertical partial surgery (CP), and the other treated exclusively with radiotherapy. Each patient had otorhinolaryngological, nasofibroscopic and video fluoroscopic evaluations after treatment. Differences between groups were compared using the - square test. Results. Twenty patients per group were entered in this study, predominantly males of similar age. Both groups presented a high incidence of aspiration symptoms (55% in RT and 35% in CP). There were no significant differences between both groups. Discussion and Conclusion. A high incidence of swallowing disorders in patients treated for early laryngeal cancer was found. It should then be considered as a frequent alteration in this group of patients, either treated with RT or CP

    Laryngeal cleft is an anomaly of failed posterior closure of the larynx. Most cases are diagnosed and need treatment early in life due to respiratory and swallowing problems. We report an unusual case of a 66-year-old man with an asymptomatic laryngeal cleft until treatment for hypopharyngeal cancer. During concurrent chemoradiotherapy (CCRT), despite reduced tumor volume, he presented severe dysphagia and dyspnea, followed by severe pneumonia twice. Because CCRT had to be discontinued, a pharyngolaryngectomy was performed for the cancer treatment. The resected specimen showed total removal of the tumor and a total longitudinal cleft of the cricoid cartilage, classified as a type III laryngeal cleft by the Benjamin and Inglis' classification. A review of computed tomography images indicated that the redundant mucosa from bilateral edges closed the separation of the posterior cricoid cartilage and narrowed the laryngeal airway during CCRT. Adult presentations of laryngeal cleft are quite rare with only ten reported cases in English literature; the present case is of the oldest patient. Undiagnosed cases with laryngeal cleft may exist asymptomatically or without severe symptoms. The awareness of this condition may increase its diagnosis as a cause of diseases such as aspiration and recurrent pneumonia even in adult patients. Copyright © 2017 Elsevier B.V.

    Full Text Available A 37-year-old male athlete was diagnosed with primary tracheal adenoid cystic carcinoma following investigation for dyspnea, wheeze, and eventual stridor. Preoperative bronchoscopy revealed a highly vascular tumor 4 cm distal to the cricoid with no gross disease extending to the carina. Imaging revealed circumferential tracheal irregularity immediately inferior to the cricoid, with no definite cricoid invasion. Locoregional extension of disease was noted invading the thyroid and abutment of the carotid approximately 180°. Intraoperative findings identified tracheal mucosal disease extending distal to the carina and proximally at the cricothyroid joints where bilateral functional recurrent nerves were preserved. A decision made to preserve the larynx given the inability to fully resect distal tracheal disease. A 5 cm sleeve resection of the trachea was made with a cricotracheal anastomosis following suprahyoidal muscle release and laryngeal drop-down. The patient was treated with adjuvant radiotherapy including platinum based chemotherapy in an effort to maximise local control. PET scanning three months after therapy revealed no FDG uptake locally or distally.

    Prior studies suggest that history of allergy and infections early in life might be inversely associated with cancer. We explored the association between allergies, recent influenza infections and laryngeal cancer risk. We used data from a case-control study which included 229 cases of laryngeal cancer and 769 population controls matched for age and sex. History of a physician-diagnosed allergy, influenza-like infections in the past 5 years, smoking, alcohol consumption and occupational exposure to carcinogens were self-reported. Allergies were classified into two groups (Type I and Type IV), according to the underlying immunologic mechanism. Conditional logistic regression models were fitted using laryngeal cancer as the outcome, adjusting for smoking, alcohol consumption and occupational exposure and stratified for age and sex. Having any allergy was not associated significantly with laryngeal cancer. Although Type I and Type IV allergies were non-significantly associated with laryngeal cancer, Type IV allergies showed a strong inverse association after adjusting for smoking and alcohol (OR 0.50, 95 % CI 0.22-1.2). Participants who reported at least one influenza-like infection during the past 5 years were significantly less likely to have laryngeal cancer (OR 0.57, 95 % CI 0.39-0.81). After considering fever (≥38.5 °C) as a criterion for influenza infection, the association between influenza infection and laryngeal cancer was even stronger (OR 0.29, 95 % CI 0.13-0.63). We found no significant association between any allergy and laryngeal cancer, some indication of an inverse association between Type IV allergy and laryngeal cancer, whereas recent influenza infections were inversely associated with laryngeal cancer risk.

    Background: Patients treated with radiation therapy for laryngeal cancer often experience voice problems. The aim of this randomized controlled trial was to assess the efficacy of voice rehabilitation for laryngeal cancer patients after having undergone radiation therapy and to investigate whether differences between different tumor localizations with regard to rehabilitation outcomes exist. Methods and Materials: Sixty-nine male patients irradiated for laryngeal cancer participated. Voice recordings and self-assessments of communicative dysfunction were performed 1 and 6 months after radiation therapy. Thirty-three patients were randomized to structured voice rehabilitation with a speech-language pathologist and 36 to a control group. Furthermore, comparisons with 23 healthy control individuals were made. Acoustic analyses were performed for all patients, including the healthy control individuals. The Swedish version of the Self Evaluation of Communication Experiences after Laryngeal Cancer and self-ratings of voice function were used to assess vocal and communicative function. Results: The patients who received vocal rehabilitation experienced improved self-rated vocal function after rehabilitation. Patients with supraglottic tumors who received voice rehabilitation had statistically significant improvements in voice quality and self-rated vocal function, whereas the control group did not. Conclusion: Voice rehabilitation for male patients with laryngeal cancer is efficacious regarding patient-reported outcome measurements. The patients experienced better voice function after rehabilitation. Patients with supraglottic tumors also showed an improvement in terms of acoustic voice outcomes. Rehabilitation with a speech-language pathologist is recommended for laryngeal cancer patients after radiation therapy, particularly for patients with supraglottic tumors

    Full Text Available Background: Hypothyroidism is a well-documented complication after treatment of laryngeal cancer and is particularly significant among patients undergoing laryngectomy. We investigated the frequency of hypothyroidism in patients treated with total laryngectomy for laryngeal cancer. We also evaluated the effect of neck radiotherapy on thyroid function after total laryngectomy for laryngeal cancer. Methods: In a cross-sectional study, we evaluated 31 patients with laryngeal squamous cell carcinoma (mean age 53.6 years. Among these patients, 14 were treated with surgery only and 17 were treated with surgery plus radiotherapy. Laboratory evaluation included levels of thyroid stimulating hormone (TSH, free T4, free T3, and antithyroid antibodies both preoperatively and postoperatively at the first day, as well as one and six months after surgery. Results: All patients had normal thyroid function before treatment; however, after 6 months, five patients (16.1% were hypothyroid. Of these, three patients (9.6% had subclinical symptoms, including elevated thyroid-stimulating hormone with normal free T4, and two patients (6.5% showed clinical symptoms of hypothyroidism. Radiotherapy and neck dissection were significantly associated with higher incidences of hypothyroidism. Conclusion: Our data suggest that hypothyroidism occurs in a substantial proportion of patients undergoing surgery for laryngeal cancer. The results indicate that thyroid function studies should be routinely performed in the follow-up care of laryngeal cancer patients, especially if radiotherapy and neck dissection were part of the treatment. We suggest that this approach will improve the patient's quality of life and diminish the co-morbidity associated with this kind of surgery.

    Transoral laser microsurgery (TLM) for early to intermediate laryngeal squamous cell cancer (SCC) can be technically challenging when adequate exposure of the posterior laryngeal compartment is required due to the presence of the orotracheal tube. The goal of our study was to analyze the efficacy of high frequency jet ventilation (HFJV) in achieving appropriate laryngeal exposure and safe oncologic resection of lesions located in such a position. We reviewed the clinical records of 62 patients affected by Tis-T2 SCC of the posterior laryngeal compartment treated by TLM between 02/2012 and 12/2016. The cohort was divided into two groups according to the anesthesiologic technique used: Group A included patients treated using intraoperative infraglottic HFJV, while Group B encompassed patients treated by standard orotracheal intubation. The main outcome was postoperative surgical margin status. Group comparison analysis was performed. Significant difference in deep margin status was observed between the two groups: in Group A, the rate of negative deep margins was 86% compared to 56% in Group B ( p  = 0.04). A trend of better overall and superficial margin control was observed for patients treated using HFJV (Group A), although no statistical significance was achieved. Use of HFJV during TLM allows easier and safer management of patients affected by Tis-T2 SCC of the posterior laryngeal compartment, reducing the rates of positive superficial and deep surgical margins.

    Radiotherapy (RT) is considered as the best treatment for early laryngeal cancer in terms of survival and preservation of voice. Quality of life (QOL) must also be assessed after new treatments, such as laser treatment or laryngomicrosurgery. The QOL after RT was assessed in 61 patients (57 men and 4 women) with histologically proven laryngeal or hypopharyngeal cancer (glottis T1-2, 48 : supraglottis 11 : hypopharynx, 2). Cobalt-60 gamma rays were emitted via lateral opposed portals that included the glottis/larynx area. The delivered dose was 53 to 70 Gy/23 to 35 Fr (median, 60 Gy/30 Fr). Assessment was done by interview of physicians at periodic follow-up examinations of patients. The census period was June to December 1990. Patients' ages ranged from 37 to 82 years (median, 62 years) at treatment and 38 to 88 years (median, 68 years) at QOL assessment. Most patients enjoyed the similar daily activities and job status as before. Thirty-seven of 61 patients felt occasional hoarseness after RT, and 21 refrained from loud speech. All patients could use the telephone easily, except for one patient who had severe hearing loss. Many patients stopped smoking cigarettes, but most drank as before RT. There were no significant differences in lifestyle quality between less than and more than 5 years after RT. This QOL assessment is applicable to patients with laryngeal cancer. One half of patients treated by RT have symptoms compatible with chronic laryngitis. This study confirms that RT yields good QOL and voice quality for patients with laryngeal cancer. (author)

    Highlights: • PET/MRI is feasible and useful for primary staging of laryngeal cancer. • PET/MRI simultaneously provides morphological, metabolic and functional parameters of tumoral laryngeal lesions. • PET/MRI allows an appropriate tumoral staging in terms of lesion extension with significant impact on therapeutic strategies. - Abstract: Objectives: To evaluate the relationship between metabolic 18Fluoro-Deoxyglucose-Positron Emission Tomography (18FDG/PET) and morpho-functional parameters derived by Magnetic Resonance Imaging (MRI) in patients with histologically proven laryngeal cancer. To assess the clinical impact of PET/MRI examination on patient’s staging and treatment planning. Methods: 16 patients with histologically proven laryngeal cancer were enrolled and underwent whole body PET/CT followed by a dedicated PET/MRI of the head/neck region. Data were separately evaluated by two blinded groups: metabolic (SUV and MTV), diffusion (ADC) and perfusion (K trans , V e , k ep and iAUC) maps were obtained by positioning regions of interest (ROIs). Tumoral local extension assessed on PET/MRI was compared to endoscopic findings. Results: A good inter-observer agreement was found in anatomical location and local extension of PET/MRI lesions (Cohen’s kappa 0.9). PET/CT SUV measures highly correlate with ones derived by PET/MRI (e.g., p = 0.96 for measures on VOI). Significant correlations among metabolic, diffusion and perfusion parameters have been detected. PET/MRI had a relevant clinical impact, confirming endoscopic findings (6 cases), helping treatment planning (9 cases), and modifying endoscopic primary staging (1 case). Conclusions: PET/MRI is useful for primary staging of laryngeal cancer, allowing simultaneous collection of metabolic and functional data and conditioning the therapeutic strategies.

    Laryngeal radionecrosis is one of the most troublesome late complications of radiotherapy, because it is frequently resistant to treatment and laryngectomy is required in the worst case. Here, we report a case of laryngeal radionecrosis, successfully treated by use of hyperbaric oxygen (HBO) therapy, in which laryngectomy was avoided. A 67-year-old male received radical chemoradiotherapy (CRT) for mesopharyngeal cancer, which included radiotherapy with a total dose of 71.4 Gy/38 Fr and chemotherapy with CDDP + S-1. He developed dyspnea and throat pain 9 months after completion of CRT. Laryngoscopy revealed vocal cord impairment because of severe laryngeal edema. He was diagnosed as having laryngeal radionecrosis and initially received conservative therapy combined with antibiotics, steroids, and prostaglandins. Because his dyspnea was persistent despite this treatment, HBO therapy was administered 20 times, and resulted in complete remission of the dyspnea. HBO therapy, therefore, is regarded as an effective conservative therapeutic option for laryngeal radionecrosis. (author)

    Full Text Available Objective Laryngeal cancer is the most common type of cancer in the head and neck. Human papillomavirus (HPV represents a group of >150 related viruses. Infection with certain types of HPV can cause some types of cancer. This study aimed to evaluate the sociodemographic and histopathologic characters of squamous cell carcinoma of the larynx and its relationship to HPV subtype 16 (HPV-16. Study design Cross-sectional. Setting Tertiary university hospitals at 5 districts in Egypt (Minia, Cairo, Giza, Qaluobia, and Bani Seuif. Subjects and Methods This cross-sectional study was conducted on 50 adult patients with laryngeal cancer who were admitted at 5 tertiary care hospitals in Egypt from January 2014 through December 2014. All patients were subjected to a comprehensive preoperative assessment, histopathologic assessments of tumor biopsies, and immunohistochemical staining for HPV-16. Results HPV-16 immunostaining was positive in 9 patients (18%. A significant correlation between HPV-16 immunoreactivity and tumor grade ( P < .001 was detected, with no significant correlation between HPV-16 immunoreactivity and other clinical and pathologic variables. Conclusion The frequency of HPV-16 in laryngeal carcinoma is 18%, and there is significant correlation between HPV-16 and tumor grade.

    One hundred and twenty-nine patients have been interviewed 9 to 15 months following treatment for laryngeal cancer to determine the post treatment quality of voice and life. The patients were subdivided into 3 groups, successfully irradiated T1 and T2 patients, (89 patients), successfully irradiated T3 and T4 patients (24 patients) and those treated by surgery (16 patients). Ninety-three percent of T1 and T2 patients and 79% of T3 and T4 patients were working following treatment as compared to 44% of the surgery patients. Ninety-eight percent of the T1 and T2 and 87.5% of the T3 and T4 patients were able to use the telephone normally as compared to 12% of the surgery patients. Similarly major differences between the successfully irradiated patients and the surgically treated patients in terms of ability to live a normal social life have been noted. The patients also rated their voice in terms of volume, pitch, ability to communicate, quality, rate of speech, flow of speech and dry throat. In every parameter of rating of the voice, with the exception of dryness of the throat, the successfully irradiated patients in all stage groupings had better ratings than the surgery group. Since, in Toronto, survival in advanced glottic and supraglottic cancer is the same using radical radiation with surgery in reserve as survival with primary surgery, it is concluded in view of the superior quality of voice and life in the successfully irradiated patients that irradiation with surgery in reserve is the optimal treatment for these patients. We also concluded that the measurement of quality of life in patients with cancer of the larynx is of vital importance in determining optimal treatment and that further studies in this area are indicated

    The results of combined treatment of 98 laryngeal cancer patients followed up for 1.5-3 years were analysed. Of them 68 received a preoperative radiotherapy course conbined with the metronidazole. The drug was given in the form of a sugar syrup suspension at a dose of 100-150 mg/kg 2.5-3 hours before irradiation, at 5 Gy twice a week reaching a summary focal dose of 20 Gy. Thirty patients received radiation therapy without metronidazole. Altogether 4 preoperative radiotherapy methods were used. An analysis of the results showed a significant improvement of the cure rates for laryngeal cancer patients using metronidazole. A better healing of postoperative wounds was noted. The author proved the appropriateness of preoperative irradiation by mean fractions up to a summary focal dose of 20 Gy combined with metronidazole and subsequent (on the last or next day of irradiation) radical operation

    Endoscopic CO 2 laser surgery (ELS) is a widely accepted treatment modality for early laryngeal cancer. Commonly re- ported advantages of ELS are good oncologic results with low incidence of complications. Although less common if com- pared with open procedures, complications following ELS can be very serious, even with lethal outcome. They can range from intraoperative endotracheal tube fire accidents to early and late postoperative sequels that require intensive medical treatment, blood tra...

    The purpose of this study has been to establish the level of RCAS1 – a membrane protein expressed in various cancer cells and able to induce apoptosis of CTLs and NK cells in pharyngeal and laryngeal cancer and its clear surgical margin – with respect to clinicopathological features and to patient's follow up and evaluate its possible role in cancer relapse. A total of 122 tissue samples were obtained: 51 samples from laryngeal and pharyngeal squamous cell carcinoma, 51 samples from the clear surgical margins of these tumors, and 20 tissue samples derived from the healthy mucous membranes of the upper respiratory tract mucosa of patients without cancerous tumors. Patients were observed for a total of 4 years following surgical treatment. The level of RCAS1 expression was assessed by immunohistochemistry and Western blot. RCAS1 was identified in all laryngeal and pharyngeal carcinomas and in almost all the clear surgical margin samples. The level of RCAS1 expression was significantly higher in the cancerous samples than in the clear surgical margins and was determined to be related to the grade of the cancer and the presence of lymph node metastases. In cases of cancer relapse, significantly higher levels of RCAS1 expression were observed in the clear surgical margins. Selective cytotoxic immune cell suppression concomitant with tumor growth and associated with RCAS1 expression seems to be an important event connected with cancer relapse

    Observational studies have reported an inverse relationship between selenium status (blood or toenail) and the risk of laryngeal cancer; however, the impact of low serum selenium level on survival has not been evaluated. We conducted a prospective study of 296 patients diagnosed with laryngeal cancer in Szczecin, Poland. Serum selenium was measured at diagnosis and prior to treatment. Patients were followed from the date of diagnosis to death at five years. Vital status was obtained by linkage to the Polish National Death Registry. The five-year survival after diagnosis was 82.0% (95% CI: 68% to 91%) for individuals in the highest quartile of serum selenium (> 66.8 μg/L) and was 28.6% (95% CI 19% to 42%) for individuals in the lowest quartile (selenium, compared to those in the highest quartile. The corresponding multivariate HR was 3.07 (95% CI 1.59 to 5.94). This study suggests that a selenium level in excess of 70 μg/L is associated with improved outcome among patients undergoing treatment for laryngeal cancer. Further studies are needed to evaluate if selenium supplementation to achieve this level might improve overall prognosis.

    Background and purpose: Tumor volume (TV) is recognized as a prognostic factor of treatment outcome for head and neck tumors but is not routinely included in the treatment decision-making process. The purpose of the study was to define its prognostic role for patients with T2 laryngeal cancer. Material and methods: TV of 160 patients who underwent RT between 2002 and 2006 for T2 laryngeal squamous cell carcinoma were reviewed. The tumor was located in the glottis and epiglottis in 82 (51 %) and 78 (49 %) patients, respectively. TV was manually contoured on pretreatment, planning, contrast-enhanced CT scans and the volumetric measurement (cm 3 ) was calculated by the volume algorithm. Results: The median TV value was 2.01 cm 3 (range 0.15-21.68 cm 3 ). The median TV was significantly lower in patients with glottic tumors (p < 0.0001), N0 (p < 0.001), or well histopatologically differentiated tumors (p = 0.01). A significant correlation between TV, hemoglobin concentration (p < 0.01), and total dose (TD; p < 0.001) was observed. On univariate analyses, TV influenced local control (LC; p = 0.02) and overall survival (OS, p < 0.001). On multivariate analysis, both age (HR 1.038, p = 0.03) and TV (HR = 1.075, p = 0.01) remained significantly related to LC and OS (age: HR 1.038, p = 0.005; TV: HR 1.097, p = 0.0001). Conclusion: Large TV worsen prognosis of patients with T2 laryngeal cancer. A large TV is more common for supraglottic, poorly differentiated tumors and may suggest higher risk of nodal spread. The routine estimation of TV prior to therapy may be essential in order to select the best treatment option for patients with T2 laryngeal cancer. (orig.)

    Full Text Available The thyroid gland is an important endocrine organ, which has a significant influence on human organism from the perinatal period and throughout the whole life, participating in the regulation of metabolism. The most common variant of thyroid dysfunction is hypothyroidism, which causes different disorders in various organs and systems, including psycho-emotional sphere. This can burden comorbidities and particularly malignant processes.Laryngeal cancer is the most common type of head and neck cancer. Despite the visual availability of this localization for diagnosis, more than 50% of cases stay timely unrecognized. Many cases are found out at stages III and IV, which requires expanded operations and causes traumatization because of disruption or loss of such important functions as breathing, swallowing, speech, causing long-term or permanent disability. This makes laryngeal cancer significant medical and social and economic problem.One of the leading treatments for cancer of the larynx is external beam radiotherapy. Thyroid gland gets into the radiation area and may take more than 50% of the total focal dose. The most common outcome of post-radiation inflammation is fibrosis of thyroid tissue due to lesions of the blood vessels and destruction of thyrocytes. It causes the development of hypothyroidism, which exacerbate stress caused by cancer and by aggressive antitumor therapy. Also, hypothyroidism adversely affects the patients’ condition during the postoperative period.Despite the fact that the diagnosis of hypothyroidism is pretty simple, and replacement therapy with L-thyroxine is cheap and available, many doctors don’t monitorthyroid function in cancer patients at all or don’t make all necessary tests.Thus, timely detection of hypothyroidism is extremely important during and after the treatment of laryngeal cancer. Early prescribing adequate treatment helps to reduce the incidence of complications.

    Laryngeal and hypopharyngeal cancer, in particular T4a disease associated with cartilage invasion and extralaryngeal spread, needs to be evaluated accurately because treatment can impact heavily on a patient's quality of life. Reliable imaging tools are therefore indispensible. CT offers high spatial and temporal resolution and remains the preferred imaging modality. Although cartilage invasion can be diagnosed with acceptable accuracy by applying defined criteria for combinations of erosion, lysis and transmural extralaryngeal spread, iodine-enhanced tumors and non-ossified cartilage are sometimes difficult to distinguish. MR offers high contrast resolution for images without motion artifacts, although inflammatory changes in cartilage sometimes resemble cartilage invasion. With dual-energy CT, combined iodine overlay images and weighted average images can be used for evaluation of cartilage invasion, since iodine enhancement is evident in tumor tissue but not in cartilage. Extralaryngeal spread can be evaluated from CT, MR or dual-energy CT images and the routes of tumor spread into the extralaryngeal soft tissue must be considered; (1) via the thyrohyoid membrane along the superior laryngeal neurovascular bundle, (2) via the inferior pharyngeal constrictor muscle, and (3) via the cricothyroid membrane. Radiologists need to understand the advantages and limitations of each imaging modality for staging of laryngeal and hypopharyngeal cancer

    Full Text Available Cutaneous metastasis from laryngeal carcinoma is a rare occurrence. A 55-year-old male patient with supraglottic cancer was treated with concurrent chemoradiation. Eighteen months later, he presented with ulceroproliferative growth on dorsum of the right hand. Biopsy revealed metastatic squamous cell carcinoma. Further investigations revealed underlying bone destruction with lung metastasis. In view of poor general condition and widespread dissemination of disease, palliative radiotherapy was delivered to the hand of the patient. He achieved satisfactory palliation in form of pain relief, control of bleeding, and discharge. The present report serves to emphasize the importance of properly diagnosing metastatic spread to unusual sites. Such metastasis is rare and is associated with a poor prognosis. Treatment is usually aimed at providing pain relief in these patients with limited life expectancy. Hence, we present a case of extensive cutaneous metastasis from laryngeal carcinoma with review of the literature.

    Purpose: To investigate the prognostic value of hemoglobin (Hb) concentration in patients with laryngeal cancer treated with postoperative radiotherapy (pRT). Methods and Materials: The records of 835 patients who underwent pRT between 1980 and 2003 were reviewed. Most patients (526 of 835 patients; 63%) were in advanced clinical stages (T3-T4) and 371 of 835 patients (44%) were node positive. Total laryngectomy had been performed in 676 of 835 patients (81%). Median Hb concentration before (Hb0) and after pRT (Hb1) was the same (13.3 g/dl). However, individual differences between Hb1 and Hb0 (dHb) varied within a broad range (-8.8; 5.0 g/dl). Univariate and multivariate analyses were performed to identify variables significantly associated with locoregional control (LRC), metastases-free survival, and overall survival. Results: Patients with dHb greater than 0 had significantly improved 5-year LRC compared with those with dHb of 0 or less (80% vs. 72%, p = 0.01). Conversely, when categorized, neither Hb0 nor Hb1 had a significant influence on LRC. In multivariate analysis, dHb remained a prognostic factor for LRC (p = 0.01) among the other variables, which included overall radiation treatment time and nodal status. None of the Hb-related variables significantly influenced metastases-free or overall survival. Conclusion: Individual change in Hb concentration during the course of pRT (dHb) rather than Hb level before or after pRT appeared as an independent prognostic factor for LRC in this set of patients

    The ways of medical and social-occupational rehabilitation after a course of radiotherapy in patients with respiratory system cancer have been determined. Medical rehabilitation in patients with lung cancer comprises expedient planning of radiotherapy by means of systematic medicamental treatment. It is shown that it is necessary to place the patients in special rehabilitation departments after radiotherapy of carry out the treatment of pneumonities

    To validate questionnaires on voice, speech, and swallowing among laryngeal cancer patients, to assess the need for and use of rehabilitation services, and to determine the association between voice, speech, and swallowing problems, and quality of life and distress. Laryngeal cancer patients at least three months post-treatment completed the VHI (voice), SHI (speech), SWAL-QOL (swallowing), EORTC QLQ-C30, QLQ-HN35, HADS, and study-specific questions on rehabilitation. Eighty-eight patients and 110 healthy controls participated. Cut off scores of 15, 6, and 14 were defined for the VHI, SHI, and SWAL-QOL (sensitivity > 90%; specificity > 80%). Based on these scores, 56% of the patients reported voice, 63% speech, and 54% swallowing problems. VHI, SHI, and SWAL-QOL scores were associated significantly with quality of life (EORTC QLQ-C30 global quality of life scale) (r = .43 (VHI and SHI) and r = .46 (SWAL-QOL)) and distress (r = .50 (VHI and SHI) and r = .58 (SWAL-QOL)). In retrospect, 32% of the patients indicated the need for rehabilitation at time of treatment, and 81% of these patients availed themselves of such services. Post-treatment, 8% of the patients expressed a need for rehabilitation, and 20% of these patients actually made use of such services. Psychometric characteristics of the VHI, SHI, and SWAL-QOL in laryngeal cancer patients are good. The prevalence of voice, speech, and swallowing problems is high, and clearly related to quality of life and distress. Although higher during than after treatment, the perceived need for and use of rehabilitation services is limited. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Purpose: To investigate the safety and efficacy of boron neutron capture therapy (BNCT) as a larynx-preserving treatment option for patients with recurrent laryngeal cancer. Methods and Materials: Six patients with locally recurrent squamous cell laryngeal carcinoma and 3 patients with persistent laryngeal cancer after prior treatment were treated with BNCT at the FiR1 facility (Espoo, Finland) in 2006 to 2012. The patients had received prior radiation therapy with or without concomitant chemotherapy to a cumulative median dose of 66 Gy. The median tumor diameter was 2.9 cm (range, 1.4-10.9 cm) before BNCT. Boron neutron capture therapy was offered on a compassionate basis to patients who either refused laryngectomy (n=7) or had an inoperable tumor (n=2). Boronophenylalanine-fructose (400 mg/kg) was used as the boron carrier and was infused over 2 hours intravenously before neutron irradiation. Results: Six patients received BNCT once and 3 twice. The estimated average gross tumor volume dose ranged from 22 to 38 Gy (W) (mean; 29 Gy [W]). Six of the 8 evaluable patients responded to BNCT; 2 achieved complete and 4 partial response. One patient died early and was not evaluable for response. Most common side effects were stomatitis, fatigue, and oral pain. No life-threatening or grade 4 toxicity was observed. The median time to progression within the target volume was 6.6 months, and the median overall survival time 13.3 months after BNCT. One patient with complete response is alive and disease-free with a functioning larynx 60 months after BNCT. Conclusions: Boron neutron capture therapy given after prior external beam radiation therapy is well tolerated. Most patients responded to BNCT, but long-term survival with larynx preservation was infrequent owing to cancer progression. Selected patients with recurrent laryngeal cancer may benefit from BNCT.

    Three-dimensional dose distributions were computed for the photon radiotherapy of laryngeal and hypopharyngeal cancers using a pair of opposing lateral beams in fixed positions. Treatment plans obtained under various irradiation conditions ( 60 Co gamma unit, photon beams from a 8 MeV and a 15 MeV linear accelerator) are analyzed and compared. The 8 MeV and 15 MeV plans are somewhat superior to the cobalt ones in all cases. Simulations show that extreme care is needed in positioning the isocentre: an accuracy of ±3 mm is required in the median sagittal plane. (author) 21 refs.; 11 figs

    Radiotherapy and chemo-radiotherapy are generally effective for early laryngeal cancer. However, the local pain due to the mucositis induced by the irradiation often prevents the completion of treatment. Since 2005, we have administrated an opioid to control a pain if necessary. We divided 40 early laryngeal cancer patients into 2 groups of 20 patients, and the influence of treatment with the opioid was investigated in the two groups. One group received the induction of the opioid, and patients were treated from 2008 to 2010. The others were treated before 2004 and did not receive the opioid. Both groups frequently used various painkillers, however, the time after the initiation of treatment when subjects began taking the painkiller was shorter for the after induction group than the before induction group. Ten percent of patients paused radiation treatment in the after induction group, and 70% had to temporarily stop treatment in the before induction group. Thus, the interruption of radiation was significantly less frequent in the after induction group than the before induction group. Our results indicate that the introduction of opioids for radiation patients improved the course of cancer treatment. (author)

  11. Epigenetic Dysregulation in Laryngeal Squamous Cell Carcinoma

    2012-01-01

    Full Text Available Laryngeal carcinoma is a common head and neck cancer with poor prognosis. Patients with laryngeal carcinoma usually present late leading to the reduced treatment efficacy and high rate of recurrence. Despite the advance in the use of molecular markers for monitoring human cancers in the past decades, there are still no reliable markers for use to screen laryngeal carcinoma and follow the patients after treatment. Epigenetics emerged as an important field in understanding the biology of the human malignancies. Epigenetic alterations refer to the dysregulation of gene, which do not involve the alterations of the DNA sequence. Major epigenetic changes including methylation imbalance, histone modification, and small RNA dysregulation could play a role in the development of human malignancies. Global epigenetic change is now regarded as a molecular signature of cancer. The characteristics and behavior of a cancer could be predicted based on the specific epigenetic pattern. We here provide a review on the understanding of epigenetic dysregulation in laryngeal carcinoma. Further knowledge on the initiation and progression of laryngeal carcinoma at epigenetic level could promote the translation of the knowledge to clinical use.

    The purpose of this study was to evaluate the laser-radiation combined therapy for T2N0M0 laryngeal-glottic cancer in order to preserve the larynx. The subjects consisted of 52 patients with T2N0M0 laryngeal-glottic cancer treated with laser-radiation combined therapy between 1980 and 1999. Patients ranged in age from 40-88 years, with a median of 70 years, and included 51 men and one woman. During this period, treatment was administered with different radiation devices ({sup 60}Co or 4 MV-X ray), and 40-72 Gy (median, 60Gy) of radiation therapy were administered. Tumor and treatment characteristics were correlated with local control at a median follow-up of 61 months (range 12-210 months). Concurrent chemotherapy was administered to 32 patients; 29 were treated with 5-FU and vitamin A (FAR), and 3 were treated with low-dose CDDP. Post treatment vocal function was examined in 37 patients. The voice was evaluated in terms of four parameters: maximum phonation time (MPT), mean air flow rate during phonation over a comfortable duration (MFR), fundamental frequency range of phonation (F0 range), and sound pressure level range of phonation (SPL range). The five-year cause-specific-survival rate was 98.0%, and the local control rate was 91.8%. Three of 4 patients who had locally relapsed were administered total laryngectomy as salvage therapy. One patient was administered the tracheostomy for late complication. The actuarial laryngeal preservation rate was 92.3%. We did not find any significant relationship between local relapse and extent of disease, subglottic extension, or anterior commissure involvement. Concurrent chemotherapy was not a significant prognostic factor. Laser debulking followed by radiation therapy did not change the voice significantly except the F0 range. We conclude that the laser-radiation combined therapy for T2N0M0 laryngeal-glottic cancer was effective therapy for not only preservation of the voice but also for vocal function. (author)

    Laryngeal cancer constitutes and important problem from the nutritional point of view, both due to the effect of the tumor itself as due to the aggressive treatment to which the majority of these patients are subjected. To evaluate the incidence of nutritional support on the morbid-mortality and on the number of hospitalization days, we compare a group A of 61 patients diagnosed with laryngeal squamous cell carcinoma, who received treatment from the Department of Nutrition, with another, similar group B, who received a standard diet. a complete evaluation of the nutritional status was done (anthropometric biochemical and immunological parameters) one day prior to the surgery and two weeks after. The differences of age (61 vs 63 years), cigarette smoking (31 vs 34), excessive alcohol ingestion (34 vs 29), location of the tumor and type of surgery, were not significant. The nutritional treatment used in group A was enteral nutrition by means of a 12-F polyurethane naso-gastric tube, while in group B it was the ground up culinary diet through a large caliber naso-gastric tube. There were no significant differences in the mortality (1/0) or in the surgical complications (9/10); nevertheless, the average number of hospital days was clearly lower in group A (18 days) compared to group B (24 days) (p < 0.005). The evolution of the evaluation parameters of the nutritional status was analyzed, as well as the administered dietary formulae, added medication, and the complications of the technique. Regulated nutritional support may contribute to the decrease of the hospitalization period of patients operated on for laryngeal cancer.

    Fifty-seven patients with hypopharyngeal cancer treated by irradiation at Kyushu University Hospital between 1985 and 1992 were analyzed retrospectively. They included 53 men and 4 women, and their ages ranged from 39 to 83 years (mean, 63 years). Two patients had stage I, 7 had stage II, 13 had stage III, and 35 had stage IV disease according to the Union Internationale Contre le Cancer (UICC) (1997) classification. Initially, they were irradiated in the conventional way with a dose of 30 Gy, and 17 patients with good response were irradiated to curative dose (more than 60 Gy), and 32 patients with poor response were operated immediately. Medically inoperable or unresectable patients were treated in a semiradical way (n=8). The 5-year overall and cause-specific survival rates were 46% and 51%, respectively. Five-year cause-specific survival rates were 88% for stages I and II (n=9), 67% for stage III (n=13), and 35% for stage IV (n=35). Five-year cause-specific survival according to treatment method was 58% for surgery and 51 % for curative radiotherapy. There was no statistically significant difference between the two rates. These results suggest that initial radiation response is an important factor in deciding on the following treatment method. Curative radiotherapy for hypopharyngeal cancer according to initial radiation response is a desirable treatment strategy. (author)

  16. Effect of radiotherapy on the immunocompetence in patients with bronchogenic carcinoma and laryngeal cancer

    1981-01-01

    We evaluated the immunocompetence of 80 patients with bronchogenic carcinoma and 17 patients with laryngeal cancer undergoing radiotherapy, using collectively many types of immunological parameters. In patients with bronchogenic carcinoma, no significant difference was seen with PHA and PPD skin tests, but the reactivity of PHA skin tests gradually decreased in the course of treatment. It was assumed that radiotherapy might not interfere with the recognition of antigen. Lymphocyte blastoid transformations with PHA, Con A and PWM were all inhibited significantly. Since these three mitogens can stimulate the different groups of lymphocyte, the inhibition to the proliferative function of lymphocyte due to radiotherapy would seem to cover a wide area, including T and B lymphocyte. Concerning the comparative radiosensitivity of T and B lymphocyte, no significant result was obtained. However, in the dose of 20Gy the percentage of T lymphocyte decreased, while the percentage of B lymphocyte increased. The percentage of early rosetts, one subset of T cell, decreased more sensitively than that of T cell, but there was no significant difference. Immunocompetence of cases in stage III, which was significantly high before treatment, decreased to the same level as those in stage IV according to the treatment. In patients with laryngeal cancer, lymphocyte counts and reactivity of PHA skin tests were not influenced by radiotherapy, and then reactivity of PPD skin tests and lymphocyte blastoid transformations with PHA and Con A tended to increase instead.

  17. Hyperspectral Imaging Using Flexible Endoscopy for Laryngeal Cancer Detection

    2016-08-01

    Full Text Available Hyperspectral imaging (HSI is increasingly gaining acceptance in the medical field. Up until now, HSI has been used in conjunction with rigid endoscopy to detect cancer in vivo. The logical next step is to pair HSI with flexible endoscopy, since it improves access to hard-to-reach areas. While the flexible endoscope’s fiber optic cables provide the advantage of flexibility, they also introduce an interfering honeycomb-like pattern onto images. Due to the substantial impact this pattern has on locating cancerous tissue, it must be removed before the HS data can be further processed. Thereby, the loss of information is to minimize avoiding the suppression of small-area variations of pixel values. We have developed a system that uses flexible endoscopy to record HS cubes of the larynx and designed a special filtering technique to remove the honeycomb-like pattern with minimal loss of information. We have confirmed its feasibility by comparing it to conventional filtering techniques using an objective metric and by applying unsupervised and supervised classifications to raw and pre-processed HS cubes. Compared to conventional techniques, our method successfully removes the honeycomb-like pattern and considerably improves classification performance, while preserving image details.

    Purpose: To investigate the flavopiridol effect on radiation-induced apoptosis and expression of apoptosisrelated genes of human laryngeal and lung cancer cells. Materials and Methods: A human laryngeal cancer cell line, AMC-HN3 and a human lung cancer cell line, NCI-H460, were used in the study. The cells were divided into four groups according to the type of treatment: 1) control groups; 2) cells that were only irradiated; 3) cells treated only with flavopiridol; 4) cells treated with flavopiridol and radiation simultaneously. The cells were irradiated with 10 Gy of X-rays using a 4 MV linear accelerator. Flavopiridol was administered to the media at a concentration of 100 nM for 24 hours. We compared the fraction of apoptotic cells of each group 24 hours after the initiation of treatment. The fraction of apoptotic cells was detected by measurement of the sub-G1 fractions from a flow cytometric analysis. The expression of apoptosis-regulating genes, including cleaved caspase-3, cleaved PARP (poly (ADP-ribose) polymerase), p53, p21, cyclin D1, and phosphorylated Akt (protein kinase B) were analyzed by Western blotting. Results: The sub-G1 fraction of cells was significantly increased in the combination treatment group, as compared to cells exposed to radiation alone or flavopiridol alone. Western blotting also showed an increased expression of cleaved caspase-3 and cleaved PARP expression in cells of the combination treatment group, as compared with cells exposed to radiation alone or flavopiridol alone. Treatment with flavopiridol down regulated cyclin D1 expression of both cell lines but its effect on p53 and p21 expression was different according to each individual cell line. Flavopiridol did not affect the expression of phophorylated Akt in both cell lines. Conclusion: Treatment with flavopiridol increased radiation-induced apoptosis of both the human laryngeal and lung cancer cell lines. Flavopiridol effects on p53 and p21 expression were different according

    2003-01-01

    In order to develop the national guide-lines for the standardization of radiotherapy we are planning to establish a web-based, on-line data-base system for laryngeal cancer. As a first step this study was performed to accumulate the basic clinical information of laryngeal cancer and to determine the items needed for the data-base system. We analyzed the clinical data of patients who were treated under the diagnosis of laryngeal cancer from January 1998 through December 1999 in the South-west area of Korea. Eligibility criteria of the patients are as follows: 18 years or older, currently diagnosed with primary epithelial carcinoma of larynx, and no history of previous treatments for another cancers and the other laryngeal diseases. The items were developed and filled out by radiation oncologist who are members of Korean Southwest Radiation Oncology Group. SPSS v10.0 software was used for statistical analysis, Data of forty-five patients were collected. Age distribution of patients ranged from 28 to 88 years (median, 61). Laryngeal cancer occurred predominantly in males (10: t sex ratio). Twenty-eight patients (62%) had primary cancers in the glottis and 17 (38%) in the supraglottis. Most of them were diagnosed pathologically as squamous cell carcinoma (44/45, 98%). Twenty-four of 28 glottic cancer patients (86%) had AJCC (American Joint Committee on Cancer) stage l/ll, but 50% (8/16) had in supraglottic cancer patients (p=0.02). Most patients (89%) had the symptom of hoarseness. Indirect laryngoscopy was done in all patients and direct laryngoscopy was performed in 43 (98%) patients. Twenty-one of 28 (75%) glottic cancer cases and 6 of 17 (35%) supraglottic cancer cases were treated with radiation alone, respectively. The combined treatment of surgery and radiation was used in 5 (18%) glottic and 8 (47%) supraglottic patients. Chemotherapy and radiation was used in 2 (7%) glottic and 3 (18%) supraglottic patients. There was no statistically significant difference in

    We aim to assess the correlation of tumor and nodal staging to survival in pT3N+ and T4aN0 laryngeal cancer with subgroup analysis within stage IVa (pT4N0 and pT3N2). Retrospective cohort study with systematic review of the literature. Hotel Dieu de France University Hospital (tertiary referral center). Laryngeal cancer patients' registries were reviewed from 1998 to 2012 selecting pT3N+ and pT4aN0 patients treated by primary total layngectomy. Overall survivals were compared using Log rank and Kaplan-Meier analysis. A systematic review was performed by 2 reviewers including all the articles reporting the outcome of these categories of patients. Online databases, including PubMed and EMBASE, were used. Reference sections of identified studies were examined for additional articles. Thirteen T3N+ patients and 19 T4aN0 patients treated by primary total laryngectomy were included. Five-year overall survival for T3N+, T3N2 and T4aN0 was respectively 33%, 32.1% and 73.7%. Due to the small sample, the difference was not significant. The systematic review revealed three articles reporting overall survival outcome for the T4N0 group and 6 articles for the T3N+. At 5years, the survival ranged from 62.5% to 73% in T4N0 and from 32.2% to 77% in T3N+. In advanced stage laryngeal cancer, T4aN0 tends toward a better survival than T3N+ especially when compared to T3N2 although they are grouped in the same TNM stage IVa. Copyright © 2015 Elsevier Inc.

    Three-dimensional dose distributions were computed for the photon radiotherapy of laryngeal and hypopharyngeal cancers using a pair of symmetrical wedges in a coaxial pair of opposing lateral beams in fixed positions. Treatment plans obtained with wedged and open fields under various irradiation conditions ( 60 Co gamma unit, photon beams from a 6 MeV and a 15 MeV linear accelerator) are analyzed and compared. The homogeneity of dose distribution for the target volume at cobalt gamma ray was moderately improved using wedges. The use of 6 MeV x-ray wedging slightly decreases the uniformity of the tumor dose distribution. At 15 MeV wedging produces no improvement on the homogeneity of the dose delivered to the target volume. Thus it seems that the application of wedges is not advantageous in this field of radiotherapy. (author) 8 refs.; 13 figs

    Background and purpose: The purpose of this retrospective study was to report on the efficacy of radiotherapy alone in patients with T4-stage laryngeal cancer and to establish the prognostic value of (a) the size and location of the extralaryngeal tumor extensions and (b) of emergency tracheostomy. Patients and methods: A group of 114 patients were treated with definitive radiotherapy between 1990 and 1996. The piriform recess was involved in 37 cases (33 %), the base of the tongue and glosso-epiglottic vallecula in 34 cases (30 %), and the hypopharyngeal wall in 10 cases (9 %). In 16 cases (14 %), emergency tracheostomy was performed before radiotherapy. The mean total dose was 68 Gy (range, 60-77.6 Gy). The mean treatment time was 49 days (range, 42-74 days). Results: Actuarial 3-year local control (LC) was noted in 42 % of patients, disease-free survival (DFS) in 35 %, and overall survival (OS) in 40 %. The best prognosis was for the lesion suspected of cartilage infiltration: 56 % 3-year LC. The worst results were noted in the cases with massive infiltrations spreading from the larynx through the hypopharynx: 13 % 3-year LC. Emergency tracheostomy before radiotherapy was significantly connected with the worst treatment results (p = 0.000): 3-year LC in patients with tracheostomy was 0 % vs. 48 % in patients without tracheostomy. Conclusion: Conventional radiotherapy of T4 laryngeal cancer is a method of treatment with limited effectiveness. The efficacy of radiotherapy is dependent on the location and extent of extralaryngeal infiltrations. Emergency tracheostomy is a prognostic factor connected with the worst prognosis. (orig.)

    Objective To evaluate the performance of narrow band imaging (NBI) for the diagnosis of laryngeal cancer and to compare the diagnostic value of NBI with that of white light endoscopy. Data Sources PubMed, Embase, Cochrane Library, and CNKI databases. Review Methods Data analyses were performed with Meta-DiSc. The updated Quality Assessment of Diagnostic Accuracy Studies-2 tool was used to assess study quality and potential bias. Publication bias was assessed with the Deeks's asymmetry test. The protocol used in this article has been published on PROSPERO and is in accordance with the PRISMA checklist. The registry number for this study is CRD42015025866. Results Six studies including 716 lesions were included in this meta-analysis. The pooled sensitivity, specificity, and diagnostic odds ratio for the NBI diagnosis of laryngeal cancer were 0.94 (95% confidence interval [95% CI]: 0.91-0.96), 0.89 (95% CI: 0.85-0.92), and 142.12 (95% CI: 46.42-435.15), respectively, and the area under receiver operating characteristics curve was 0.97. Among the 6 studies, 3 evaluated the diagnostic value of white light endoscopy, with a sensitivity of 0.81 (95% CI: 0.76-0.86), a specificity of 0.92 (95% CI: 0.88-0.95), and a diagnostic odds ratio of 33.82 (95% CI: 14.76-77.49). The evaluation of heterogeneity, calculated per the diagnostic odds ratio, gave an I 2 of 66%. No marked publication bias ( P = .84) was detected in this meta-analysis. Conclusion The sensitivity of NBI is superior to white light endoscopy, and the potential value of NBI needs to be validated in future studies.

    Background and purpose: Although patients with early stage (T1/T2) laryngeal cancer (LC) are thought to have a low incidence of malnutrition, severe weight loss is observed in a subgroup of these patients during radiotherapy (RT). The objective of this study was to evaluate weight loss and nutrition-related symptoms in patients with T1/T2 LC during RT and to select predictive factors for early identification of malnourished patients. Methods: Of all patients with T1/T2 LC, who received primary RT between 1999 and 2007, the following characteristics were recorded: sex, age, TNM classification, tumour location, radiation schedule, performance status, quality of life, weight loss, and nutrition-related symptoms. The association between baseline characteristics and malnutrition (>5% weight loss during RT) was investigated by Cox regression analysis. Results: The study population consisted of 238 patients. During RT, 44% of patients developed malnutrition. Tumour location, TNM classification, RT on the neck nodes, RT dose, nausea/vomiting, pain, swallowing, senses problems, trouble with social eating, dry mouth and the use of painkillers were all significantly associated with malnutrition. In the multivariate analysis, RTs on both the neck nodes (HR 4.16, 95% CI 2.62-6.60) and dry mouth (HR 1.72, 95% CI 1.14-2.60) remained predictive. Nevertheless, RT on the neck nodes alone resulted in the best predictive model for malnutrition scores. Conclusions: Patients with early stage laryngeal cancer are at risk of malnutrition during radiotherapy. Radiotherapy on the neck nodes is the best predictor of malnutrition during radiotherapy. Therefore, we suggest to offer nutritional counselling to all the patients who receive nodal irradiation.

    Highlights: •HIF-1α-regulated INPP4B enhances glycolysis. •INPP4B regulates aerobic glycolysis by inducing HK2 via Akt-mTOR pathway. •Blockage of INPP4B and HK2 sensitizes radioresistant laryngeal cancer cells to radiation and anticancer drug. •INPP4B is associated with HK2 in human laryngeal cancer tissues. -- Abstract: Inositol polyphosphate 4-phosphatase type II (INPP4B) was recently identified as a tumor resistance factor in laryngeal cancer cells. Herein, we show that INPP4B-mediated resistance is associated with increased glycolytic phenotype. INPP4B expression was induced by hypoxia and irradiation. Intriguingly, overexpression of INPP4B enhanced aerobic glycolysis. Of the glycolysis-regulatory genes, hexokinase 2 (HK2) was mainly regulated by INPP4B and this regulation was mediated through the Akt-mTOR pathway. Notably, codepletion of INPP4B and HK2 markedly sensitized radioresistant laryngeal cancer cells to irradiation or anticancer drug. Moreover, INPP4B was significantly associated with HK2 in human laryngeal cancer tissues. Therefore, these results suggest that INPP4B modulates aerobic glycolysis via HK2 regulation in radioresistant laryngeal cancer cells.

    The aim of this study was to analyze whether inhibition of cyclooxygenase-2 by celecoxib and the subsequent enhancement in the proliferation of natural killer T (NKT) cells could play a role in dendritic cell (DC)-based laryngeal cancer (LC) immunotherapy. Peripheral blood mononuclear cells were obtained from 48 male patients diagnosed with LC and 30 control patients without cancer disease. Neoplastic cell lysate preparations were made from cancer tissues obtained after surgery and used for in vitro DCs generation. NKT cells proliferation assay was performed based on 3 H-thymidine incorporation assay. An increased proliferation of NKT cells was obtained from control patients compared to NKT cells obtained from LC patients regardless of the type of stimulation or treatment. In the patient group diagnosed with LC, COX-2 inhibition resulted in a significantly enhanced proliferation of NKT cells when stimulated with autologous DCs than NKT cells stimulated with DCs without COX-2 inhibition. These correlations were not present in the control group. Higher proliferation rate of NKT cells was also observed in non-metastatic and highly differentiated LC, which was independent of the type of stimulation or treatment. COX-2 inhibition could be regarded as immunotherapy-enhancing tool in patients with LC. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

    Full Text Available Introduction. Currently, a great importance is being attached to improvement of the surgical component of combination treatment of locally advanced laryngeal cancer. New technological capabilities (transoral microsurgery of the larynx and robotic surgery offer great opportunities for early cancer stages. However, in some cases capabilities of endoscopic laser intervention are limited. Therefore, open laryngeal resection is still relevant as it serves as the only type of radical organ preservation treatment for stages Т2–Т3. But major laryngeal resection is associated with a problem of tissue defect closure.The article describes data on the use of biocompatible materials, their advantages and disadvantages. The study objective is to present experience of using a Russian allogenic bioimplant for plastic reconstruction of the opening of the larynx after laryngeal resection.Materials and methods. The authors present their experience of using a Russian bioimplant produced in collaboration with the Samara Tissue Bank of the Research Institute of Experimental Medicine and Biotechnology of the Samara State Medical University. The material was tested in anterolateral laryngeal resection with simultaneous reconstruction in 5 patients with stages Т2–Т3 laryngeal cancer and in a patient with chondrosarcoma.Conclusion. The Russian biocompatible implant served as a reliable, simple, cheap, and effective variant of plastic material for reconstruction of the larynx.

    To determine the value of CT(Computerized Tomography) in the diagnosis of laryngeal tuberculosis and to assess to what extent its characteristic findings different from those of laryngeal carcinoma. CT scans of twelve patients with laryngeal tuberculosis were reviewed and compared with those of fifteen patients with laryngeal cancer, retrospectively. Clinical symptoms, laryngoscopic examinations and the presence of pulmonary tuberculosis chest radiographs were also reviewed. In laryngeal tuberculosis, bilateral symmetric or asymmetric involvement was noted in nine(75%) patients, while unilateral involvement was seen in three(25%). This was significantly different from laryngeal cancer in which unilateral involvement was noted in twelve patients(80%). Diffuse thickening of the free margin of the epiglottis was a characteristic and frequent finding in tuberculosis(n=6, 50%). No deep submucosal infiltration of preepiglottic and paralaryngeal fat spaces is seen in tuberculosis in spite of large areas of involvement of laryngeal mucosa, while twelve patients(80%) with laryngeal cancer showed thickened deep infiltration which resulted in a submucosal mass. CT was useful in the diagnosis of laryngeal tuberculosis and its CT findings were characterized by bilateral involvement, thickening of the free margin of the epiglottis and good preservation of preepiglottic and paralaryngeal fat spaces in spite of large areas of involvement

    Multidrug resistance (MDR) poses a serious impediment to the success of chemotherapy for laryngeal cancer. To identify microRNAs and mRNAs associated with MDR of human laryngeal cancer Hep-2 cells, we developed a multidrug-resistant human laryngeal cancer subline, designated Hep-2/v, by exposing Hep-2 cells to stepwise increasing concentrations of vincristine (0.02-0.96'µM). Microarray assays were performed to compare the microRNA and mRNA expression profiles of Hep-2 and Hep-2/v cells. Compared to Hep-2 cells, Hep-2/v cells were more resistant to chemotherapy drugs (∼45-fold more resistant to vincristine, 5.1-fold more resistant to cisplatin, and 5.6-fold more resistant to 5-fluorouracil) and had a longer doubling time (42.33±1.76 vs 28.75±1.12'h, P<0.05), higher percentage of cells in G0/G1 phase (80.98±0.52 vs 69.14±0.89, P<0.05), increased efflux of rhodamine 123 (95.97±0.56 vs 12.40±0.44%, P<0.01), and up-regulated MDR1 expression. A total of 7 microRNAs and 605 mRNAs were differentially expressed between the two cell types. Of the differentially expressed mRNAs identified, regulator of G-protein signaling 10, high-temperature requirement protein A1, and nuclear protein 1 were found to be the putative targets of the differentially expressed microRNAs identified. These findings may open a new avenue for clarifying the mechanisms responsible for MDR in laryngeal cancer.

    This study compared the risk of fatal cerebrovascular accidents (CVAs) in patients with early-stage glottic laryngeal cancer receiving surgery or external beam radiation therapy (EBRT). Using a competing risks survival analysis, we compared the risk of death because of CVA among patients with early-stage glottic laryngeal cancer receiving surgery or EBRT in the Surveillance, Epidemiology, and End Results (SEER) database. The cumulative incidence of fatal CVA at 15 years was higher in patients receiving EBRT (2.8%; 95% confidence interval [CI], 2.3% to 3.4%) compared to surgery (1.5%; 95% CI, 0.8% to 2.3%; p = .024). In multivariable competing risks regression models, EBRT remained associated with an increased risk of fatal CVA compared to surgery (adjusted hazard ratio [HR], 1.75; 95% CI, 1.04-2.96; p = .037). Treatment for early-stage glottic laryngeal cancer with EBRT was associated with a small increase in the risk of late fatal CVA events relative to surgery. Copyright © 2013 Wiley Periodicals, Inc.

    The role of precautionary radiotherapy of the neck in laryngeal cancers (exept T1-T2 glottic and some T1 supraglottic cancers) NO at the clinical staging was investigated. Two-hundred and fifty-three patients were examined: 143 were irradiated only on T, and 110 also on the neck. Radiotherapy of the neck in the latter group was performed either by means of two large opposed fields of photon beams including T and N, or by means of fields of photon beams on T and electron beams (8x12 cm 2 average) on the neck, to quite exclude any risks for the spinal cord. The dose was 45-50 Gy (2 Gy/fraction/day; 5 fraction/week) in 4-5 weeks. A comparison of the results obtained in the two groups, in terms of survival-rate and relapse-free time, indicates that radiotherapy reduces the change of relapses on N (6.1% vs. 14.62% at 3 years; p=0.04) and improves the patient's survival chances (82.5% vs. 68.4% at 3 years; and 80.8% vs. 63.4% at 5 years). Our data were then compared with literature data on the importance of N field size in radiation treatment. As a rule, some authors enlarge the field to be treated to a total nodal neck irradiation, but their results are not significally different from those we obtained with 8x12 cm 2 field size

    The choices made by patients offered treatment for early laryngeal cancer with radiotherapy or transoral laser resection were reviewed. A prospective review was conducted of all patients diagnosed and treated for early laryngeal carcinoma from December 2002 to September 2009 at the Leeds Teaching Hospitals NHS Trust. A total of 209 patients with tumour stage T1 or T2 laryngeal cancer were treated; each new patient suitable for radiotherapy or transoral laser resection was seen jointly by the clinical (radiation) oncologist and head and neck surgeon, and offered the choice of treatment. Of the patients, 47.4 per cent were given a choice between radiotherapy and transoral laser resection; 51.2 per cent were advised to have radiotherapy, and there were no records for the remaining 1.4 per cent. From those given the choice, 59.6 per cent chose transoral laser resection (p < 0.02 (t-test)) and 35.4 per cent chose radiotherapy. When given the choice, a statistically significant majority of patients choose transoral laser resection rather than radiotherapy.

    Background: Installations that burn fossil fuels to generate power may represent a health problem due to the toxic substances which they release into the environment. Objectives: To investigate whether there might be excess mortality due to tumors of lung, larynx and bladder in the population residing near Spanish combustion installations included in the European Pollutant Emission Register. Methods: Ecologic study designed to model sex-specific standardized mortality ratios for the above three tumors in Spanish towns, over the period 1994-2003. Population exposure to pollution was estimated on the basis of distance from town of residence to pollution source. Using mixed Poisson regression models, we analyzed: risk of dying from cancer in a 5-kilometer zone around installations that commenced operations before 1990; effect of type of fuel used; and risk gradient within a 50-kilometer radius of such installations. Results: Excess mortality (relative risk, 95% confidence interval) was detected in the vicinity of pre-1990 installations for lung cancer (1.066, 1.041-1.091 in the overall population; 1.084, 1.057-1.111 in men), and laryngeal cancer among men (1.067, 0.992-1.148). Lung cancer displayed excess mortality for all types of fuel used, whereas in laryngeal and bladder cancer, the excess was associated with coal-fired industries. There was a risk gradient effect in the proximity of a number of installations. Conclusions: Our results could support the hypothesis of an association between risk of lung, laryngeal and bladder cancer mortality and proximity to Spanish combustion installations

    Docetaxel (DOC) has radiation-sensitizing effects because it synchronizes with the most radiation-sensitive G2/M phase of the cell cycle. From the results of concurrent radiotherapy with weekly DOC administrations in a phase I trial, dose-limiting toxicity (DLT) was mucositis and the recommended dose was 10 mg/m 2 , but the administration schedule was a problem. We planned concurrent radiation therapy in a bi-weekly DOC phase I trial to improve the larynx preservation rate and to determine which schedule and dosage of DOC would yield its inherent cytotoxic effects. We decided the maximum tolerated dose (MTD) and DLT to serve as an index of the appearance of adverse events. Patients with stage II or stage III T2N1 hypopharyngeal cancer or stage II or III laryngeal cancer were included in this study. DOC was administered on the days of initiation of bi-weekly radiation (day 1, day 15, day 29). Radiation was given (2 Gy/day: 5 days per week) for a total of 30 Fr, with a total of 60 Gy. The starting dose of DOC was 30 mg/m 2 (level 1) and the dosage was raised by 5 mg/m 2 at each level. DLT was observed due to mucositis and neutropenia at 40 mg/m 2 (level 3), the MTD was 40 mg/m 2 and the recommended dose (RD) was 35 mg/m 2 . Especially in hypopharyngeal cancer of Grade 3 or more, mucositis appeared, with swallowing difficulty in cases with a wide range of irradiation. At dosages of 35 mg/m 2 , the effectiveness was favorable and this was the suitable dosage recommended for the subsequent phase II trial. This clinical study was performed with permission of our IRB (Institutional Review Board). (author)

    To assess the environmental as well as dietary risk factors for the laryngeal and pharyngeal cancer (LPC) in patients treated at Liaquat University Hospital, Jamshoro. Methodology: Total 395 LPC patients and 550 healthy persons were interviewed through a standard questionnaire specially designed to study the risk factors for LPC disease. Significance level (p<0.05) was assessed with chi-squared test (95% confidence interval) and odds ratios were measured for associations of factors with LPC by logistic regression analysis. Results: The age range was 37.6 to 56.6 years with majority of males as compared to females. Majority of LPC patients were married, underweight and labor workers. Use of non-branded oil, smoking and illiteracy and sun exposure 1 hour were significantly positively associated with LPC. Mainpuri was observed at highest significant positive risk factor for LPC. Less vegetables, less fruit and less meat consumption as well as, deep fried/fried foods and more tea intake were found significantly positively associated with LPC disease. Conclusion: Labor work, Illiteracy, smoking, use of non-branded cooking oil, sun exposure 1 hour, manipuri, consumption of less vegetables, less fruit and less meat, deep fried/fried foods and more tea intake were found significantly positively associated risk factors of LPC.

    Laryngeal necrosis is a rare complication of radiotherapy for early-staged laryngeal or hypopharyngeal cancer. However, when it occurs, there is no definitive treatment and laryngectomy is frequently required. Here we present a case of advanced laryngeal necrosis (grade 4, Chandler classification) treated with hyperbaric oxygen (HBO) therapy. A 60-year-old woman received radiotherapy with 64.8 Gy for early-staged hypopharyngeal cancer in combination with three courses of cisplatin (40 mg/body/week). She developed pharyngeal pain and progressive dyspnea because of laryngeal edema 3 months after the completion of radiotherapy, and received an emergent tracheostomy. In order to differentiate radiation injury from cancer recurrence, biopsies were obtained under direct laryngoscopy and showed intense necrosis without malignancy. Since laryngeal radionecrosis was presumed, the patient received HBO therapy at 2 atmospheres absolute (ATA) with 100% O 2 for 2 hours per session. After 20 HBO treatments, laryngeal edema improved and her clinical symptoms including pharyngeal pain, swallowing pain and dysphagia, were ameliorated significantly. However, decannulation has not been achieved because of bilateral vocal cord fixation. We considered that HBO therapy was effective in the present case and that HBO therapy should be recommended as a therapeutic option whenever laryngeal necrosis occurs and there is a chance to save the larynx.

    Purpose/objective: To improve the local control rate while minimizing the complication rate in the treatment of T2 laryngeal cancer, we conducted a Phase II trial of twice-a-day fractionated radiotherapy (TDFR) and compared the results with those of historical control treated by conventional radiotherapy. Materials and Methods: Between 1966 and 1995, 126 cases with T2 laryngeal cancer were treated by radiotherapy in our department by Cobalt equipment. Median field sige was 42cm 2 . Since 1986, we started TDFR. Fifty-eight cases were treated by TDFR, among them there were 6 cases of supraglottic lesion, 49 cases of glottic, and 3 cases of subglottic. Their age ranged from 47 to 82 (mean 64), and all but 1 cases were male. They were irradiated with a fraction dose of 1.5 Gy twice a day at least 6 hours apart, 10 times a week to a total dosage of 66 - 78 Gy (mean 69Gy) in 30 to 53 days (median 43 days). Fifty-four (93 %) of the cases needed a split during radiotherapy for acute mucosal reaction. The other 68 cases were treated by conventional radiotherapy (control group). There were 8 cases of supraglottic lesion, 57 of glottic, and 3 of subglottic. Their age ranged from 33 to 86 (mean 62), and 62 cases (91 %) were male. They were irradiated with a fraction dose of 1.8 Gy (38 cases) or 2 Gy (30 cases) to a total dosage of 59 - 72Gy (mean 66 Gy) in 43 - 69 days (median 51 days). Thirteen (19 %) of the cases needed a split during radiotherapy. Acute and late reactions were graded into 4 grades and compared. Results: Five year actuarial local control rate was 79.0 % in the TDFR group and 75.6 % in the control group (n.s.). Five year actuarial survival rate was 79.7 % in the TDFR group and 77.7 % in the control group (n.s.). Five year actuarial cause-specific survival rate was 96.4 % in the TDFR group and 95.2 % in the control group (n.s.). Five year actuarial local control rate of glottic cases was 78.6 % in the TDFR group and 78.8 % in the control group (n.s.). As for

    Surgical complication rates of salvage laryngectomy after chemoradiotherapy (CRT) have been reported to be high. Wound complications after salvage laryngectomy following concurrent chemoradiotherapy (CCRT) were analyzed. Eighty-six patients who had undergone total laryngectomy for laryngeal cancer at Hokkaido University Hospital between 1990 and 2006 were divided into three groups according to preoperative treatments received: total laryngectomy (TL) group (n=35) without radiotherapy (RT) or CCRT, RT-TL group (n=17) with RT alone, CRT-TL group (n=34) with low-dose CCRT. Major wound complications were defined as major pharyngocutaneous fistulas which caused inpatient care for more than eight weeks or which were closed by surgery, bleeding that required surgical reintervention, and wound infection or skin necrosis that caused inpatient care for more than eight weeks. Minor complications were self-limited, managed with local wound care, and did not prolong inpatient care for more than eight weeks. We also analyzed wound complications of larynx preservation surgery after CCRT. Overall wound complications, both major and minor, were observed in 26% of the TL group, 35% of the RT-TL group, and 47% of the CRT-TL group. Major wound complications were observed in 11%, 18%, and 29%, respectively. A considerable but not statistically significant increase in the incidence of overall and major wound complications was observed between the TL and CRT-TL groups (p=0.082 and 0.078, respectively). Pharyngocutaneous fistulas were the most common complication, occurring in 14/86 (16%) of patients. Patients who developed pharyngocutaneous fistulas after CCRT tended to require surgical reintervention and longer periods before the initiation of oral intake. Wound complications were observed in 2/3 (67%) of patients who had undergone larynx preservation surgery. High incidences of wound complications and poor wound recovery in patients undergoing salvage laryngectomy following CCRT should

    The purpose of this study was to commission and clinically test a robotic stereotactic delivery system (CyberKnife, Sunnyvale, CA) to treat early-stage glottic laryngeal cancer. We enrolled 15 patients with cTis-T2N0M0 carcinoma of the glottic larynx onto an institutional review board (IRB)-approved clinical trial. Stereotactic body radiotherapy (SBRT) plans prescribed 45 Gy/10 fractions to the involved hemilarynx. SBRT dosimetry was compared with (1) standard carotid-sparing laryngeal intensity-modulated radiation therapy (IMRT) and (2) selective hemilaryngeal IMRT. Our results demonstrate that SBRT plans improved sparing of the contralateral arytenoid (mean 20.0 Gy reduction, p <0.001), ipsilateral carotid D{sub max} (mean 20.6 Gy reduction, p <0.001), contralateral carotid D{sub max} (mean 28.1 Gy reduction, p <0.001), and thyroid D{sub mean} (mean 15.0 Gy reduction, p <0.001) relative to carotid-sparing IMRT. SBRT also modestly improved dose sparing to the contralateral arytenoid (mean 4.8 Gy reduction, p = 0.13) and spinal cord D{sub max} (mean 4.9 Gy reduction, p = 0.015) relative to selective hemilaryngeal IMRT plans. This “phantom-to-clinic” feasibility study confirmed that hypofractionated SBRT treatment for early-stage laryngeal cancer can potentially spare dose to adjacent normal tissues relative to current IMRT standards. Clinical efficacy and toxicity correlates continue to be collected through an ongoing prospective trial.

    Background: DNA-dependent protein kinase catalytic subunit (DNA-PKcs) is known to function in several types of cancer. In this study, we investigated the expression and clinicopathologic significance of DNA-PKcs in laryngeal squamous cell carcinoma (LSCC). Methods: We conducted a retrospective study of 208 patients with advanced-stage LSCC treated at Sun Yat-sen University Cancer Center, Guangzhou, China. We assessed DNA-PKcs and p16INK4a (p16) status using immunohistochemistry. We examined the association between DNA-PKcs expression and clinicopathologic features and survival outcomes. To evaluate the independent prognostic relevance of DNA-PKcs, we used univariate and multivariate Cox regression models. We estimated overall survival (OS) and distant metastasis-free survival (DMFS) using the Kaplan-Meier method. Results: Immunohistochemical analyses revealed that 163/208 (78.4%) of the LSCC tissue samples exhibited high DNA-PKcs expression. High DNA-PKcs expression was significantly associated with survival outcomes ( P = 0.016) and distant metastasis ( P = 0.02; chi-squared test). High DNA-PKcs expression was associated with a significantly shorter OS and DMFS than low DNA-PKcs expression ( P = 0.029 and 0.033, respectively; log-rank test), and was associated with poor OS in the p16-positive subgroup ( P = 0.047). Multivariate analysis identified DNA-PKcs as an independent prognostic indicator of OS and DMFS in all patients ( P = 0.039 and 0.037, respectively). Conclusions : Our results suggest that patients with LSCC in whom DNA-PKcs expression is elevated have a higher incidence of distant metastasis and a poorer prognosis. DNA-PKcs may represent a marker of tumor progression in patients with p16-positive LSCC.

    The objective of the present study was to enhance the effectiveness of rehabilitation of the patients presenting with laryngeal cancer after the resection of the organ and laryngotomy with tracheoesophageal by-pass and endoprosthetics. Our experience in this field is based on the treatment of 102 patients. They were distributed by the nosological forms as follows: primary laryngeal cancer in 97 patients including T1NoMo - 8 (8.2%), T2NoMo - 63 (65%), T3NoMo - 18 (17.6%), T2N1Mo - 1 (0.9%), T4NoMo - 3 (2.9%), and T4N1M0 - 4 (3.9%), root of the tongue cancer spreading over the vestibular part of the larynx in one patient, laryngeal sarcoma in one patient, relapse of cancer following the full-dose radiotherapy and organ-sparing surgery in 3 patients. Laryngeal resection was performed in 83 patients; 19 patients underwent laryngectomy with tracheoesophageal by-pass and endoprosthetics using a domestically manufactured voice prosthesis. The systemic approach to the rehabilitation of the patients and the use of the proposed treatment algorithm made it possible to restore the function of the larynx by means of organ-sparing surgery in 79 (95.1%) of the 83 patients. The vocal function in the patients following laryngectomy with tracheoesophageal by-pass and endoprosthetics was restored in 18 (94.7%) of the 19 patients.

    Full Text Available Introduction: Leishmaniasis is classified into three clinical presentations: visceral, coetaneous and mucocutaneous. The latter is usually secondary to hematogenous spread after months or years of skin infection and can manifest as infiltrative lesions, ulcerated or vegetating in nose, pharynx, larynx and mouth, associated or not with ganglionics infarction. Laryngeal involvement is part of the differential diagnosis of lesions in this topography as nonspecific chronic laryngitis, granulomatosis and even tumors of the upper aerodigestive tract presenting atypical evolution. Sometimes it is difficult for the correct diagnosis of Leishmaniasis, with description of cases in the literature were conducted improperly. Objective: The objective of this study is to report a case of laryngeal Leishmaniasis addressing the difficulty of diagnosis, complications and treatment applied. Case Report: A patient with pain throat, dysphagia, odynophagia, dysphonia and weight loss, with no improvement with symptomatic medication. At telelaringoscopy, infiltrative lesion showed nodular supraglottis. He underwent a tracheotomy for airway obstruction and biopsy with immunohistochemical study for a definitive diagnosis of laryngeal Leishmaniasis. The patient was referred to the infectious diseases that initiated treatment with N-methylglucamine antimoniate with satisfactory response to therapy. Final Comments: Faced with a clinical suspicion of granulomatous diseases, it is essential to follow protocol laboratory evaluation associated with histological injury, to get a precise definition etiological without prolonging the time of diagnosis. Medical treatment for mucosal Leishmaniasis, recommended by the World Health Organization, was adequate in the case of laryngeal disorders, with complete resolution of symptoms.

    Recently, p16 has been included in the TNM guideline for oropharyngeal carcinomas. The role of HPV and p16 in hypopharyngeal and laryngeal carcinomas has not yet been established sufficiently. Hundred and thirty-four patients with hypopharyngeal and laryngeal carcinomas were included in this retrospective analysis. Only patients with known HPV status were eligible for the investigation. Survival probabilities were estimated for different risk factors. Eighty-five patients presented with laryngeal carcinoma and 49 patients with hypopharyngeal carcinoma. 8% were HPV positive (10.6% laryngeal, 4.1% hypopharyngeal carcinoma). Median follow-up time was 58 months. We observed a significantly better overall survival for patients with an early tumor stage compared to advanced carcinoma. One of the hypopharyngeal HPV positive carcinomas was also p16 positive and one was p16 negative. Of the nine HPV positive laryngeal carcinomas, four were p16 positive and five p16 negative. Neither patients who were HPV positive nor patients positive for p16 showed a significantly better outcome than HPV or p16 negative patients. In contrast, nicotine pack-years showed a highly significant correlation with survival in our patient collective. The data suggest that tumor stage and nicotine exposure seem to have the highest impact on survival in hypopharyngeal and laryngeal squamous cell carcinoma patients. There is no evidence for a better survival for p16 positive or HPV positive patients with hypopharyngeal or laryngeal squamous cell carcinoma. HPV seems to play a minor role in these entities of head and neck carcinoma.

    After concurrent chemoradiation for head and neck squamous cell cancer, patients with laryngeal incompetence may not recover function. We assessed variables predicting tracheostomy dependence as a measure of poor laryngeal function after chemoradiation. Retrospective Analysis of 109 patients treated with chemoradiation for locoregionally advanced laryngohypopharyngeal squamous cell cancers between 1992 and 2013. Median follow-up was 17.0 and 17.2 months for tracheostomy and nontracheostomy dependent patients, respectively. For all patients, multivariate analysis demonstrated persistent tracheostomy was associated with pretreatment tracheostomy, subglottic extension, three-dimensional conformal radiotherapy (3DCRT) and postradiotherapy lymphadenectomy. When analyzed by primary site, tracheostomy dependence was associated with pretreatment tracheostomy, subglottic extension, and 3DCRT in larynx primaries, and with pretreatment tracheostomy and feeding tube dependency in hypopharynx primaries. Tracheostomy dependence did not impact local control, progression-free survival or overall survival on univariate analysis. After curative chemoradiation, long-term tracheostomy was associated with pretreatment tracheostomy, subglottic extension, postradiotherapy lymphadenectomy, and 3DCRT but did not impact outcomes. These factors may inform treatment decision making regarding organ preservation approaches for locally advanced laryngeal and hypopharyngeal cancers. 4. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

    l-DOPA decarboxylase (DDC) plays an essential role in the enzymatic synthesis of dopamine and alterations in its gene expression have been reported in several malignancies. Our objective was to analyze DDC messenger RNA (mRNA) and protein expression in laryngeal tissues and to evaluate the clinical implication of this molecule in laryngeal cancer. In this study, total RNA was isolated from 157 tissue samples surgically removed from 100 laryngeal cancer patients. A highly sensitive real-time polymerase chain reaction methodology based on SYBR Green I fluorescent dye was developed for the quantification of DDC mRNA levels. In addition, Western blot analysis was performed for the detection of DDC protein. DDC mRNA expression was revealed to be significantly downregulated in primary laryngeal cancer samples compared with their nonmalignant counterparts (P = .001). A significant negative association was also disclosed between DDC mRNA levels and TNM staging (P = .034). Univariate analysis showed that patients bearing DDC-positive tumors had a significantly decreased risk of death (hazard ratio = 0.23, P = .012) and local recurrence (hazard ratio = 0.32, P =.006), whereas DDC expression retained its favorable prognostic significance in the multivariate analysis. Kaplan-Meier curves further demonstrated that DDC-positive patients experienced longer overall and disease-free survival periods (P = .006 and P = .004, respectively). Moreover, DDC protein was detected in both neoplastic and noncancerous tissues. Therefore, our results suggest that DDC expression status could qualify as a promising biomarker for the future clinical management of laryngeal cancer patients.

    Ling Feng

    Full Text Available Long non-coding RNA (lncRNA plays an important role in tumorigenesis. However, the expression pattern and function of lncRNAs in laryngeal squamous cell carcinoma (LSCC are still unclear. To investigate the aberrantly expressed lncRNAs and mRNAs in advanced LSCC, we screened lncRNA and mRNA expression profiles in 9 pairs of primary Stage IVA LSCC tissues and adjacent non-neoplastic tissues by lncRNA and mRNA integrated microarrays. Gene Ontology and pathway analysis were performed to find out the significant function and pathway of the differentially expressed mRNAs, gene-gene functional interaction network and ceRNA network were constructed to select core mRNAs, and lncRNA-mRNA expression correlation network was built to identify the interactions between lncRNA and mRNA. qRT-PCR was performed to further validate the expressions of selected lncRNAs and mRNAs in advanced LSCC. We found 1459 differentially expressed lncRNAs and 2381 differentially expressed mRNAs, including 846 up-regulated lncRNAs and 613 down-regulated lncRNAs, 1542 up-regulated mRNAs and 839 down-regulated mRNAs. The mRNAs ITGB1, HIF1A, and DDIT4 were selected as core mRNAs, which are mainly involved in biological processes, such as matrix organization, cell cycle, adhesion, and metabolic pathway. LncRNA-mRNA expression correlation network showed LncRNA NR_027340, MIR31HG were positively correlated with ITGB1, HIF1A respectively. LncRNA SOX2-OT was negatively correlated with DDIT4. qRT-PCR further validated the expression of these lncRNAs and mRNAs. The work provides convincing evidence that the identified lncRNAs and mRNAs are potential biomarkers in advanced LSCC for further future studies.

    2006-01-01

    Purpose: The impact of concurrent chemotherapy on the local control in patients with T2N0 laryngeal cancer who receive radiation therapy (RT) was evaluated. Methods and Materials: Sixty-three patients with T2N0 laryngeal cancer who were treated by definitive RT were analyzed. The primary site of the cancer was the glottis in 50 patients, the supraglottis in 9 patients, and the subglottis in 4 patients. Thirty-six patients were treated by RT alone and the remaining 27 patients received concurrent chemoradiotherapy (CRT). Results: Complete response (CR) was obtained in 92% of the patients who received RT alone and 100% of the patients who received CRT. Voice preservation in the group who received CRT (89%) was significantly higher than that in the group treated by RT alone (61%). The 5-year disease-free survival rates in those who received concurrent CRT was significantly superior to that in the patients who received RT alone, although no significant difference was seen in the cause-specific survival rate between the 2 groups. The multivariate analysis revealed that the treatment method (RT alone vs. CRT) was the most significant risk factor that predicted recurrence after RT.

    PURPOSE/OBJECTIVE: The time factor (γ/α) in the LQ model has been considered irrelevant for the late normal tissue injury (1). The failure of the LQ model to predict spinal cord injury in the CHART protocol questions the validity of this hypothesis. In this investigation, the incidence of radiation induced laryngeal edema was evaluated retrospectively in patients treated with different dose fractionation regimes for carcinoma of glottic cancer (2). The BED values of the LQ model calculated for different values of time factor (γ/α) were correlated with the incidence of radiation induced laryngeal edema. MATERIALS AND METHODS: A retrospective analysis was carried out for 208 patients T 1 and T 2 squamous cell cancer of the vocal cord treated with radical radiotherapy during 1975-80. There were 156 patients with T 1 lesions and the remaining 52 patients had T 2 lesions. All these patients were treated with three different fractionation regimens of 60.75 Gy/ 27 F/ 39 D, 60 Gy/24 F/34 D and 50 Gy/15 F/ 22 D, using fraction sizes 2.25 Gy, 2.5 Gy and 3.33 Gy, respectively. For the minimum follow up of 4 years, the incidence of laryngeal edema was related to fraction size (see table). To investigate the importance of the time factor (γ/α) of LQ model, BED values were calculated for different values of γ/α and ∞/β = 2.0 Gy. RESULTS: As shown in the table below, the incidence of radiation induced laryngeal edema was found in 17.2% of patients with 2.25 Gy/F compared to 44.4% using 3.33 Gy/F. The TDF model failed to correlate with the incidence of laryngeal edema. The BED values of LQ model also fails to show statistically significant correlation with the incidence of late complications. However, the BED values accounting for the time factor (particularly γ/α = 1.2 Gy/day) show significant improvement in correlation with incidence of laryngeal edema. CONCLUSION: For comparable TDF values the incidence of laryngeal edema varied from 17% to 44.4%. The analysis with

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

    The purpose of this study is to present the treatment results and to identify possible prognostic indicators in patients with locally advanced hypopharyngeal carcinoma. Materials and Methods: Between October 1985 to December 2000, 90 patients who had locally advanced stage IV hypopharyngeal carcinoma were studied retrospectively. Twelve patients were treated with radiotherapy alone, 65 patients were treated with a combination of chemotherapy and radiotherapy, and 13 patients were treated with surgery and postoperative radiotherapy with or without neoadjuvant chemotherapy. Total radiation dose ranged from 59.0 to 88.2 Gy (median 70 Gy) for radiotherapy alone. Most patients had ciplatin and 5-fluorouracil, and others had cisplatin and peplomycin or vincristin. Median follow-up period was 15 months. Kaplan-Meier method was used for survival rate and Cox proportional hazard model for multivariate analysis of prognostic factors. Results: Overall 3- and 5-year survival rates were 27% and 17%, respectively. The 2-year locoregional control rates were 33% for radiotherapy alone, 32% for combined chemotherapy and radiotherapy, and 81% for combined surgery and radiotherapy (p=0.006). The prognostic factors affecting overall survival were T stage, concurrent chemo radiation and treatment response. Overall 3- and 5-year laryngeal preservation rates in combined chemotherapy and radiotherapy were 26% and 22%, respectively. Of these, the 5-year laryngeal preservation rates were 52% for concurrent chemo radiation group (n=11), and 16% for neoadjuvant chemotherapy and radiotherapy (n=54, p=0.012). Conclusion: Surgery and postoperative radiotherapy showed better results than radiotherapy alone or with chemotherapy. Radiotherapy combined with concurrent chemotherapy is an effective modality to achieve organ preservation in locally advanced hypopharyngeal cancer. Further prospective randomized studies will be required

    The quantitative and qualitative changes occurring in the fungal flora of 22 patients with oral and 9 with laryngeal carcinoma were studied during and after radiation therapy. Each patient received 6000 rad of externally applied radiation in divided doses for 5 weeks. The fungal flora was isolated from the patients' oral cavity and irradiated skin sites during irradiation and 2 weeks and 4-6 months afterwards. The number and types of fungi increased in both groups of patients after the start of irradiation and persisted at high levels for at least 4-6 months after treatment. Candida albicans and C. tropicalis were the principal yeasts isolated throughout the period studied but seven other species were also identified. All the yeast isolates were sensitive in vitro to miconazole, ketoconazole, amphotericin B and nystatin. Any of these antifungal agents should be appropriate for therapy. (author)

    The study aimed to explore and analyze the effects of health education intervention on patients with laryngeal cancer and evaluate negative emotions and quality of life after receiving postoperative radiotherapy. Furthermore the relationship between health education intervention methods and its correlation to complications and relapse rates require greater understanding. Patients with aryngeal cancer receiving surgery and postoperative radiotherapy were randomly divided into observation and control groups. A quality of life questionnaire was used to evaluate patients' current life quality as well as negative emotions experienced. The collected data was evaluated using the Self-rating Anxiety Scale (SAS) as well as the Self-rating Depression Scale (SDS). At the time of discharge, patients' satisfaction on nursing and perception of health knowledge was assessed. Three and six months after discharge, patients were given follow-up visits and questionnaire surveys to evaluate their rehabilitation. This was done in relation with the Morningside Rehabilitation Stats Scale (MRSS), incidence of complications and recurrence. The scores of negative emotions, exhibited during the study, were lower in the observation group than in the control group. A month after discharge had a positive correlation to improved quality of life. This was highlighted in the observation group in comparison with the control group. The data collected following discharge revealed an improvement in quality of life, compared with that at the time of admission. Compared with the control group, the SAS and SDS scores in the observation group were decreased a month after discharge. Compared with the scores on admission, the SAS and SDS scores in both groups were decreased one month after discharge. The observation group had a lower incidence of complications than that of the control group. Six months after discharge, in the observation group, the MRSS score was lower than before discharge while in the

    To investigate the diagnostic value of dynamic magnetic resonance imaging (MRI) and positron emission tomography/computed tomography (PET/CT) for laryngeal cancers after inadequate CT results. The study comprised 45 patients investigated for primary laryngeal cancer or recurrence-residue in which CT was considered inadequate. A mass was found in 20 patients. Dynamic MRI and PET/CT were compared for diagnosis of mass, lymph node involvement, recurrence and residue. The dynamic curves formed in dynamic MRI were investigated for diagnostic contributions. The sensitivity and specificity of the dynamic MRI, for supraglottic, glottic and subglottic location, was 100%, 80%, and 92%; 100%, 85%, and 100%, respectively. In PET/CT the sensitivity and specificity were 100% for all of those localizations. For lymph node involvement, the sensitivity of dynamic MRI and PET/CT was 100%, the specificity was 100% and 93%, respectively. For recurrence-residue, the sensitivity and specificity of dynamic MRI were 86% and 67%, respectively, with 100% sensitivity and specificity in PET/CT. The sensitivity of type A curve for detection of malignancy was 40%, and specificity was 100%. When type A and B curves were included, the sensitivity was 100%. For patients investigated for laryngeal cancer in which CT is considered inadequate, dynamic MRI or PET/CT is useful

    Full Text Available PURPOSE: The study aims to assess the feasibility of Tomotherapy-based image-guided radiotherapy (IGRT to reduce the aspiration risk in patients with non-laryngeal and non-hypopharyngeal cancer. A retrospective review of 48 patients undergoing radiation for non-laryngeal and non-hypopharyngeal head and neck cancers was conducted. All patients had a modified barium swallow (MBS prior to treatment, which was repeated one month following radiotherapy. Mean middle and inferior pharyngeal dose was recorded and correlated with the MBS results to determine aspiration risk. RESULTS: Mean pharyngeal dose was 23.2 Gy for the whole group. Two patients (4.2% developed trace aspiration following radiotherapy which resolved with swallowing therapy. At a median follow-up of 19 months (1-48 months, all patients were able to resume normal oral feeding without aspiration. CONCLUSION AND CLINICAL RELEVANCE: IGRT may reduce the aspiration risk by decreasing the mean pharyngeal dose in the presence of large cervical lymph nodes. Further prospective studies with IGRT should be performed in patients with non-laryngeal and non-hypopharyngeal head and neck cancers to verify this hypothesis.

    Laryngeal cancers are rare, encompassing around one percent of all cancers. Suspicion should be raised if a patient presents with classical signs and symptoms; i.e. dysphonia, inspiratory stridor, dysphagia, odynophagia, neck mass, or persistent cough. Laryngeal chondrosarcoma is a rare form of laryngeal cancer, the diagnosis of which can be difficult. The case in question describes an unusual presentation of one such case, and its subsequent investigation, management and outcome.

    In order to identify the genetic factors associated with the radiation-resistant human laryngeal carcinoma cell line (SQ-20B), tumor cell DNA was transfected into NIH/3T3 cells. A high incidence (six out of six) of raf sequences was found in transfected NIH/3T3 clones and the tumorigenic potential of SQ-20B DNA could be linked to genomic fragments that represent most of the kinase domain of human c-raf-1. An apparently unaltered 3.5-kilobase pair (kb) human c-raf transcript was identified in SQ-20B cells but was not observed in the transfected NIH/3T3 cell clones. Two new transcripts (4.2 kb and 2.6 kb) were found in tumorigenic clones; the large transcript was missing in a very poorly tumorigenic clone. Cytogenetic analysis indicated that the normal autosomes of chromosome 3 were absent in SQ-20B karyotypes and had formed apparently stable marker chromosomes. Unlike the recipient NIH/3T3 cell line, 30% of the transformed clone-1 metaphases had minute and double-minute chromosomes representative of amplified DNA sequences. The frequency of the c-raf-1 identification by NIH/3T3 transfection of SQ-20B DNA suggests the presence of some genetic abnormality within this locus

    Review of the literature and report of a new case of laryngeal cancer after irradiation of a benign lesion of the neck. These cases obviously become rare since benign lesions are no longer irradiated. Today the risk of inducing a second carcinoma by a successful irradiation of the first tumor becomes more important. A study of 109 patients, irradiated for laryngeal carcinoma and surviving with no evidence of disease for a period of at least 5 years has been performed. 8 of these patients developed a second primary in the previously irradiated area after 7-15 years. These second carcinomas are not rare if one considers that most patients with laryngeal carcinoma are 60-70 years old and therefore the life expectance on an average is low. These facts should be taken into consideration when deciding between surgical or radiation therapy in younger patients with high life expectance. (orig.) [de

    Objectives It is unknown if preoperative tracheostomy for persistent/recurrent laryngeal squamous cell carcinoma (LSCC) plays a role in unrecognized local disease spread and disease recurrence after salvage laryngectomy. The goals of this study were to determine the effect of preoperative tracheostomy on disease-free survival (DFS) in patients with recurrent/persistent LSCC undergoing salvage laryngectomy. Study Design Retrospective case series derived from prospectively maintained database. Setting Tertiary care academic center. Subjects Patients with recurrent/persistent LSCC after radiation/chemoradiation (RT/CRT) who underwent salvage laryngectomy at the University of Michigan from 1997 to 2015. Methods Demographic, clinical, pathologic, and survival data were collected. Kaplan-Meier survival estimates were performed. Results DFS was worse for patients with tracheostomy prior to laryngectomy than patients without a tracheostomy (5 year: 39% vs 67%; P tracheostomy prior to RT/CRT compared to patients with tracheostomy after RT/CRT or patients without a tracheostomy had worse DFS (5-year: 25%, 49%, and 67%, respectively; P tracheostomy was associated with worse DFS. In multivariable analysis, presence of a preoperative tracheostomy had a worse DFS (hazard ratio, 1.63; 95% confidence interval, 1.00-2.67; P = .048). Conclusion Preoperative tracheostomy is associated with disease recurrence in patients with persistent/recurrent LSCC undergoing salvage laryngectomy, particularly in patients who had tracheostomy prior to completion of initial RT/CRT. Notably, preoperative tracheostomy as a causal factor vs marker for disease recurrence is difficult to ascertain. Nevertheless, clinicians should be aware of the increased risk of locoregional recurrence in patients with preoperative tracheostomy when counseling on surgical salvage and when considering the role of additional therapy.

Ultrasonography and computed tomography examinations revealed mass extending from the cricoid cartilage to the left lobe of thyroid gland and thyroid cartilage. Cytology revealed possibility of cartilaginous origin, which was proven to be chondrosarcoma (Grade 1) from the biopsy specimen obtained during panendosopy. She underwent one stage radical resection and immediate reconstruction of laryngeal skeleton defect by mucocartilaginous graft from the nasal septum. Her postoperative course was optimal with preservation of the laryngeal functions. Twenty-eight months postoperatively, she had to undergo total laryngectomy as a salvage procedure for the advanced local recurrence. We report on the relatively easy technique for functional reconstruction of the large laryngeal defect with the employment cartilage graft from the nasal septum. (author)

    Purpose: To compare volumetric modulated arc radiotherapy (VMAT) technique with fixed-gantry intensity-modulated radiotherapy (IMRT) technique for locally advanced laryngeal carcinoma. Methods: CT datasets of eleven patients were included. Dual-arc VMAT and 7-field IMRT plans, which were created based on the Eclipse treatment planning system, were compared in terms of dose-volume parameters, conformity index (CI) and homogeneity index (HI) of planning target volume (PTV), as well as organ-at-risk (OAR) sparing, planning time, monitor units (MUs) and delivery time. Results: Compared with the IMRT plans, the VMAT plans provided lower D2% and better CI/HI for the high-risk PTV (PTV1), and provided better CI and comparable HI for the low-risk PTV (PTV2). Concerning the OAR sparing, the VMAT plans demonstrated significantly lower Dmax of the spinal cord (planning OAR volume, PRV) and brainstem (PRV), as well as lower Dmean and V30Gy of the right parotid. No significant differences were observed between the two plans concerning the doses delivered to the thyroid, carotid, oral cavity and left parotid. Moreover, the VMAT planning (147 ± 18 min) consumed 213% more time than the IMRT planning (48 ± 10 min). The MUs of the VMAT plans (556 ± 52) were 64% less than those of the IMRT plans (1684 ± 409), and the average delivery time (2.1 ± 0.1 min) was 66% less than that of the IMRT plans (6.3 ± 0.7 min). Conclusion: Compared with the IMRT technique, the VMAT technique can achieve superior target dose distribution and better sparing of the spinal cord, brainstem and right parotid, with less MUs and less delivery time. It is recommended for the radiotherapy of locally advanced laryngeal carcinoma.

    Purpose: To report the acute toxicity profile and compliance from a randomized Phase III trial comparing accelerated radiotherapy (AR) with accelerated radiotherapy plus carbogen and nicotinamide (ARCON) in laryngeal cancer. Methods and Materials: From April 2001 to February 2008, 345 patients with cT2–4 squamous cell laryngeal cancer were randomized to AR (n = 174) and ARCON (n = 171). Acute toxicity was scored weekly until Week 8 and every 2–4 weeks thereafter. Compliance to carbogen and nicotinamide was reported. Results: Between both treatment arms (AR vs. ARCON) no statistically significant difference was observed for incidence of acute skin reactions (moist desquamation: 56% vs. 58%, p = 0.80), acute mucosal reactions (confluent mucositis: 79% vs. 85%, p = 0.14), and symptoms related to acute mucositis (severe pain on swallowing: 53% vs. 58%, p = 0.37; nasogastric tube feeding: 28% vs. 28%, p = 0.98; narcotic medicines required: 58% vs. 58%, p = 0.97). There was a statistically significant difference in median duration of confluent mucositis in favor of AR (2.0 vs 3.0 weeks, p = 0.01). There was full compliance with carbogen breathing and nicotinamide in 86% and 80% of the patients, with discontinuation in 6% and 12%, respectively. Adjustment of antiemesis prophylaxis was needed in 42% of patients. Conclusion: With the exception of a slight increase in median duration of acute confluent mucositis, the present data reveal a similar acute toxicity profile between both regimens and a good compliance with ARCON for clinical stage T2–4 laryngeal cancers. Treatment outcome and late morbidity will determine the real therapeutic benefit.

The platelet-derived growth factor (PDGF)/AKT signaling pathway plays complex roles in tumor suppression. However, the effect of PD on the PDGF/AKT signaling pathway in laryngeal cancer and HeLa cells has not been explored. MTT assay and flow cytometry showed that PD inhibited cell proliferation and induced apoptosis in Hep-2 and AMC-HN-8 cells. Western blot analysis indicated that PD inhibited the expression levels of PDGF-B and phosphorylated AKT (p-AKT) in both cells. Treatment of PDGF-B siRNA or PDGFR inhibitor found that after the PDGF signaling was inactivated, p-AKT expression was significantly decreased in Hep-2 cells. Tumor xenograft experiment in nude mice indicated PD significantly inhibited the growth of Hep-2 cells in vivo. In conclusion, PD inhibited cell proliferation and induced apoptosis in laryngeal cancer and HeLa cells via inactivation of the PDGF/AKT signaling pathway. © 2017 Wiley Periodicals, Inc.

    The objective of this study was to evaluate preservation of organ function in the treatment of superselective intra-arterial chemoradiotherapy for advanced head and neck cancers. Among 96 patients receiving concomitant radiation and intra-arterial docetaxel, systemic cisplatin and 5-fluorouracil (FU) chemotherapy, we identified laryngeal preservation rate, studied tracheostomy cases and gastrostomy cases, and evaluated videofluoroscopic examination and videoendoscopy. Laryngeal preservation rate of hypopharyngeal cancer is very high at 96.2%, and that of laryngeal cancer is high at 71.4%. Videofluoroscopic examination revealed improved swallowing function in 2 of 12, no change in 3, slightly worse in 5, and worse in 2 patients. Following treatment, the incidence of aspiration increased to 4 patients. Videoendoscopy revealed residual vallecula in a few cases. Only 7 patients (7.3%) required a tracheostomy and 4 patients (4.2%) required a gastrostomy. Most of the patients are able to swallow after chemoradiation. Our new chemoradiation protocol is as good as other treatment modalities for maintaining organ preservation and function. (author)

    The purpose of this work was to retrospectively determine the value of intensity-modulated radiotherapy (IMRT) in patients with laryngeal and hypopharyngeal squamous cell carcinoma (LHSCC), on outcome and treatment-related toxicity compared to 3-dimensional conformal radiotherapy (3D-CRT). A total of 175 consecutive patients were treated between 2007 and 2012 at our institution with curative intent RT and were included in this study: 90 were treated with 3D-CRT and 85 with IMRT. Oncologic outcomes were estimated using Kaplan-Meier statistics; acute and late toxicities were scored according to the Common Toxicity Criteria for Adverse Events scale v 3.0. Median follow-up was 35 months (range 32-42 months; 95% confidence interval 95 %). Two-year disease-free survival did not vary, regardless of the technique used (69 % for 3D-CRT vs. 72 %; for IMRT, p = 0.16). Variables evaluated as severe late toxicities were all statistically lower with IMRT compared with 3D-CRT: xerostomia (0 vs. 12 %; p < 0.0001), dysphagia (4 vs. 26 %; p < 0.0001), and feeding-tube dependency (1 vs 13 %; p = 0.0044). The rates of overall grade ≥ 3 late toxicities for the IMRT and 3D-CRT groups were 4.1 vs. 41.4 %, respectively (p < 0.0001). IMRT for laryngeal and hypopharyngeal cancer minimizes late dysphagia without jeopardizing tumor control and outcome. (orig.)

    Full Text Available The anti-inflammatory protein annexin A1 (ANXA1 has been associated with cancer progression and metastasis, suggesting its role in regulating tumor cell proliferation. We investigated the mechanism of ANXA1 interaction with formylated peptide receptor 2 (FPR2/ALX in control, peritumoral and tumor larynx tissue samples from 20 patients, to quantitate the neutrophils and mast cells, and to evaluate the protein expression and co-localization of ANXA1/FPR2 in these inflammatory cells and laryngeal squamous cells by immunocytochemistry. In addition, we performed in vitro experiments to further investigate the functional role of ANXA1/FPR2 in the proliferation and metastasis of Hep-2 cells, a cell line from larynx epidermoid carcinoma, after treatment with ANXA1(2-26 (annexin A1 N-terminal-derived peptide, Boc2 (antagonist of FPR and/or dexamethasone. Under these treatments, the level of Hep-2 cell proliferation, pro-inflammatory cytokines, ANXA1/FPR2 co-localization, and the prostaglandin signalling were analyzed using ELISA, immunocytochemistry and real-time PCR. An influx of neutrophils and degranulated mast cells was detected in tumor samples. In these inflammatory cells of peritumoral and tumor samples, ANXA1/FPR2 expression was markedly exacerbated, however, in laryngeal carcinoma cells, this expression was down-regulated. ANXA1(2-26 treatment reduced the proliferation of the Hep-2 cells, an effect that was blocked by Boc2, and up-regulated ANXA1/FPR2 expression. ANXA1(2-26 treatment also reduced the levels of pro-inflammatory cytokines and affected the expression of metalloproteinases and EP receptors, which are involved in the prostaglandin signalling. Overall, this study identified potential roles for the molecular mechanism of the ANXA1/FPR2 interaction in laryngeal cancer, including its relationship with the prostaglandin pathway, providing promising starting points for future research. ANXA1 may contribute to the regulation of tumor growth

    To determine the safety and outcomes of induction chemotherapy followed by dose-escalated intensity-modulated radiotherapy (IMRT) with concomitant chemotherapy in locally advanced squamous cell cancer of the larynx and hypopharynx (LA-SCCL/H). A sequential cohort Phase I/II trial design was used to evaluate moderate acceleration and dose escalation. Patients with LA-SCCL/H received IMRT at two dose levels (DL): DL1, 63 Gy/28 fractions (Fx) to planning target volume 1 (PTV1) and 51.8 Gy/28 Fx to PTV2; DL2, 67.2 Gy/28 Fx and 56 Gy/28 Fx to PTV1 and PTV2, respectively. Patients received induction cisplatin/5-fluorouracil and concomitant cisplatin. Acute and late toxicities and tumor control rates were recorded. Between September 2002 and January 2008, 60 patients (29 DL1, 31 DL2) with Stage III (41% DL1, 52% DL2) and Stage IV (52% DL1, 48% DL2) disease were recruited. Median (range) follow-up for DL1 was 51.2 (12.1-77.3) months and for DL2 was 36.2 (4.2-63.3) months. Acute Grade 3 (G3) dysphagia was higher in DL2 (87% DL2 vs. 59% DL1), but other toxicities were equivalent. One patient in DL1 required dilatation of a pharyngeal stricture (G3 dysphagia). In DL2, 2 patients developed benign pharyngeal strictures at 1 year. One underwent a laryngo-pharyngectomy and the other a dilatation. No other G3/G4 toxicities were reported. Overall complete response was 79% (DL1) and 84% (DL2). Two-year locoregional progression-free survival rates were 64.2% (95% confidence interval, 43.5-78.9%) in DL1 and 78.4% (58.1-89.7%) in DL2. Two-year laryngeal preservation rates were 88.7% (68.5-96.3%) in DL1 and 96.4% (77.7-99.5%) in DL2. At a mean follow-up of 36 months, dose-escalated chemotherapy-IMRT at DL2 has so far been safe to deliver. In this study, DL2 delivered high rates of locoregional control, progression-free survival, and organ preservation and has been selected as the experimental arm in a Cancer Research UK Phase III study.

    A case-control study was realized to 400 patients, 200 of them histologically confirmed as incident cases of larynx cancer by the National Institute for Oncology and Radiobiology of Havana, and the others 200 as controls, coming from another hospitals. A survey was applied to both groups, collecting every theirs worker histories with emphasis on occupational exposure, that were codified by an expert group taking into account the carcinogens present according to the guided code of the Epidemiological Units of Environmental Cancer and the Fields Studies and Intervention of International Agency for Research on Cancer (IARC). According to the results obtained, all the patients, cases and controls, presented 1 526 tasks in their labour histories, that represented an average greater than 3 tasks for each one of them. They main activities were in the agriculture, the defence and the sugar cane industry. The most predominant exposures were to the abrasive dusts, motor emissions, mists of mineral oils, gasoline/petroleum/diesel/kerosene and pesticides. In general, the valuation of the chemical risk was considered of low intensity, 1-5% of the real time to the exposure and all had the certain probability of the agent's aggressor presence.

    Gastric cancer is the fifth most common cancer worldwide. In "Western" countries, most people are either diagnosed at an advanced stage, or develop a relapse after surgery with curative intent. In people with advanced disease, significant benefits from targeted therapies are currently limited to HER-2 positive disease treated with trastuzumab, in combination with chemotherapy, in first-line. In second-line, ramucirumab, alone or in combination with paclitaxel, demonstrated significant survival benefits. Thus, systemic chemotherapy remains the mainstay of treatment for advanced gastric cancer. Uncertainty remains regarding the choice of the regimen. To assess the efficacy of chemotherapy versus best supportive care (BSC), combination versus single-agent chemotherapy and different chemotherapy combinations in advanced gastric cancer. We searched the Cochrane Central Register of Controlled Trials, MEDLINE and Embase up to June 2016, reference lists of studies, and contacted pharmaceutical companies and experts to identify randomised controlled trials (RCTs). We considered only RCTs on systemic, intravenous or oral chemotherapy versus BSC, combination versus single-agent chemotherapy and different chemotherapy regimens in advanced gastric cancer. Two review authors independently identified studies and extracted data. A third investigator was consulted in case of disagreements. We contacted study authors to obtain missing information. We included 64 RCTs, of which 60 RCTs (11,698 participants) provided data for the meta-analysis of overall survival. We found chemotherapy extends overall survival (OS) by approximately 6.7 months more than BSC (hazard ratio (HR) 0.3, 95% confidence intervals (CI) 0.24 to 0.55, 184 participants, three studies, moderate-quality evidence). Combination chemotherapy extends OS slightly (by an additional month) versus single-agent chemotherapy (HR 0.84, 95% CI 0.79 to 0.89, 4447 participants, 23 studies, moderate-quality evidence), which is

    Full Text Available Abstract. We have studied possible interrelationships between immune system state and efficiency of neoadjuvant chemoradiotherapy in patients with cancer of larynx and hypopharynx. The neoadjuvant treatment consisted of 2 courses of paclitaxel (175 mg/m2, carboplatin (AUC-6 in 3-4 weeks, followed by radiation therapy at a multifraction dose schedule (1.2 Gy 2 times daily in 4 h, total cumulated dose was estimated as isoeffective dose of 40 Gy. A better response to chemotherapy by paclitaxel and carboplatin in the patients with cancer of larynx and hypopharynx had been associated with higher percentage of CD56+ cells and IgM levels in peripheral blood, as measured before starting cancer treatment. After completing the neoadjuvant chemo- and radiotherapy, we noted an increase in total lymphocyte counts, CD4+, CD8+, CD56+ cell numbers and IgG levels in the patients with pronounced response to chemotherapy, thus suggesting some induction of immune response in cancer patients during cytostatic therapy. These data presume a relationship between the state of immune system in the patients with head-and-neck cancer, and their response to neoadjuvant chemo- and radiotherapy. On the basis of these findings, one may suggest that immunological mechanisms make take an important part in promotion of antitumor effects produced by standard cancer treatment.

    Precision cancer medicine, the use of genomic profiling of patient tumors at the point-of-care to inform treatment decisions, is rapidly changing treatment strategies across cancer types. Precision medicine for advanced prostate cancer may identify new treatment strategies and change clinical practice. In this review, we discuss the potential and challenges of precision medicine in advanced prostate cancer. Although primary prostate cancers do not harbor highly recurrent targetable genomic alterations, recent reports on the genomics of metastatic castration-resistant prostate cancer has shown multiple targetable alterations in castration-resistant prostate cancer metastatic biopsies. Therapeutic implications include targeting prevalent DNA repair pathway alterations with PARP-1 inhibition in genomically defined subsets of patients, among other genomically stratified targets. In addition, multiple recent efforts have demonstrated the promise of liquid tumor profiling (e.g., profiling circulating tumor cells or cell-free tumor DNA) and highlighted the necessary steps to scale these approaches in prostate cancer. Although still in the initial phase of precision medicine for prostate cancer, there is extraordinary potential for clinical impact. Efforts to overcome current scientific and clinical barriers will enable widespread use of precision medicine approaches for advanced prostate cancer patients.

    This article provides a thorough review of the literature highlighting the articles that have advanced our knowledge about the sensitivity of the larynx to allergens in the air or ones consumed. This area of inquiry requires continued interest and investigation. As the field of clinical laryngology changes, and more information is discovered about the possible causal association between allergy and vocal pathologies, practicing otolaryngologists, allergists, and other medical professionals may discover more comprehensive methods to evaluate and treat their allergic patients, particularly those who present with complaints of dysphonia, dysphagia, laryngopharyngeal reflux (LPR), and/or dyspnea. There continues to be epidemiological studies designed to describe the relationship of allergy to vocal symptoms and signs. Both population and smaller studies have recently attempted to link these two conditions. Unfortunately, the patient with chronic laryngeal complaints is often tagged by default with the diagnosis of LPR and treated with proton pump inhibitors, which are not always beneficial. The endoscopic assessment may not be as reliable to make the diagnosis of LPR as the examination is subjective and the inter-rater reliability is low. It has been demonstrated by direct laryngeal provocation studies that sticky-viscous endo-laryngeal mucous is the only reliable finding consistently associated with allergy potential allergic tissue reactivity. The interrelationship of allergic sensitivity and chronic laryngitis in certain individuals is becoming clearer because our knowledge of inquiry has increased and the available routine technology to diagnose these conditions has remarkably improved. Notwithstanding these advancements, much more research is needed on this subject to reduce the frequency of mis-diagnoses and mis-management of allergic patients.

    Purpose: To retrospectively analyze the outcomes, toxicity, quality of life, and voice quality of patients with T3 laryngeal cancer treated with radiotherapy and to identify subgroups of patients in whom the addition of chemotherapy to radiotherapy is necessary. Methods and Materials: Between March 1996 and November 2009, 170 consecutive patients with T3 tumor were treated with (chemo)radiotherapy. Endpoints of the study were local control (LC), locoregional control (LRC), disease-free survival (DFS), overall survival (OS), late toxicity, quality of life, and voice handicap index. Results: After a median follow-up time of 32 months (range, 7–172), the 3-year actuarial rates of LC, LRC, DFS, and OS were 73%, 70%, 64%, and 61%, respectively, and the 5-year figures were 68%, 65%, 60%, and 49%, respectively. At last follow-up, 84 patients (49.5%) were still alive, 65 of them (77.3%) without local progression. Laryngectomy was performed in 16 patients, leaving 49 patients with anatomic organ preservation, corresponding to an actuarial laryngectomy-free survival of 58.3% at 3 years. The figures for patients treated with chemoradiotherapy and radiotherapy alone were 76.8% and 53.5%, respectively (p = 0.001). Chemoradiotherapy was the only significant predictor for LC on multivariate analysis. The overall 5-year cumulative incidence of late Grade ≥2 toxicity was 28.2%. Chemoradiotherapy, compared with radiotherapy alone, resulted in slight increase in late toxicity and slight deterioration of quality of life and voice-handicap-index scores. However, the differences were statistically not significant. Conclusion: The addition of chemotherapy to radiotherapy in T3 laryngeal cancer significantly improved LC and laryngectomy-free survival without statistically significant increases in late toxicity or deterioration of quality of life or voice handicap index.

    The management of head and neck cancer has evolved into a multidisciplinary approach in which patients are evaluated before treatment and decisions depend on prospective multi-institutional trials, as well as retrospective outcome studies. The choice of one or more modalities to use in a given case varies with the tumor site and extent, as exemplified in the treatment of laryngeal squamous cell carcinomas. The goals of treatment include cure, laryngeal voice preservation, voice quality, optimal swallowing, and minimal xerostomia. Treatment options include transoral laser excision, radiotherapy (both definitive and postoperative), open partial laryngectomy, total laryngectomy, and neck dissection. The likelihood of local control and preservation of laryngeal function is related to tumor volume. Patients who have a relatively high risk of local recurrence undergo follow-up computed tomography scans every 3-4 months for the first 2 years after radiotherapy. Patients with suspicious findings on computed tomography might benefit from fluorodeoxyglucose positron emission tomography to differentiate post-radiotherapy changes from tumor

    Indications for thyroidectomy during laryngectomy are controversial. We examined whether clinicopathologic features can predict thyroid gland involvement, and the prognostic effect of thyroid gland involvement in patients undergoing total laryngectomy. The study set out to review preoperative assessment, operation findings, pathologic findings, and follow-up data. Thyroid gland involvement was found in 11 of 53 patients (21%) undergoing total laryngectomy and thyroidectomy. Preoperative work-up failed to predict thyroid gland involvement. Thyroid gland involvement was associated with salvage procedures (p = .025), paratracheal metastases (p = .003), and poor overall survival (hazard ratio = 2.74, p = .008). Thyroid gland involvement in patients undergoing total laryngectomy is frequent and is associated with poor prognosis. Preoperative assessment failed to predict thyroid gland involvement. We believe that thyroidectomy should be considered in cases with paratracheal lymphatic spread irrespective of tumor location within the larynx. Copyright © 2011 Wiley Periodicals, Inc.

  9. Photodynamic Cancer Therapy - Recent Advances

    The basic principle of the photodynamic effect was discovered over a hundred years ago leading to the pioneering work on PDT in Europe. It was only during the 1980s, however, when 'photoradiation therapy' was investigated as a possible treatment modality for cancer. Photodynamic therapy (PDT) is a photochemotherapeutic process which requires the use of a photosensitizer (PS) that, upon entry into a cancer cell is targeted by laser irradiation to initiate a series of events that contribute to cell death. PSs are light-sensitive dyes activated by a light source at a specific wavelength and can be classified as first or second generation PSs based on its origin and synthetic pathway. The principle of PS activation lies in a photochemical reaction resulting from excitation of the PS producing singlet oxygen which in turn reacts and damages cell organelles and biomolecules required for cell function and ultimately leading to cell destruction. Several first and second generation PSs have been studied in several different cancer types in the quest to optimize treatment. PSs including haematoporphyrin derivative (HpD), aminolevulinic acid (ALA), chlorins, bacteriochlorins, phthalocyanines, naphthalocyanines, pheophorbiedes and purpurins all require selective uptake and retention by cancer cells prior to activation by a light source and subsequent cell death induction. Photodynamic diagnosis (PDD) is based on the fluorescence effect exhibited by PSs upon irradiation and is often used concurrently with PDT to detect and locate tumours. Both laser and light emitting diodes (LED) have been used for PDT depending on the location of the tumour. Internal cancers more often require the use of laser light delivery using fibre optics as delivery system while external PDT often make use of LEDs. Normal cells have a lower uptake of the PS in comparison to tumour cells, however the acute cytotoxic effect of the compound on the recovery rate of normal cells is not known. Subcellular

    Objective: Due to the multiple physical, psychological, existential, and social symptoms involved, patients with advanced cancer often have a reduced quality of life (QoL), which requires specialized palliative care (SPC) interventions. The primary objective of the present systematic review...... was to review the existing literature about SPC and its effect on QoL, on physical and psychological symptoms, and on survival in adult patients with advanced cancer. Method: We utilized a search strategy based on the PICO (problem/population, intervention, comparison, and outcome) framework and employed....... The evidence in this field of study in general is still nascent, but there is growing support for the utilization of SPC to improve the quality of life of adult patients with advanced cancer. The evidence that SPC reduces physical and psychological symptoms is moderate, while the evidence that it prolongs...

    Prognosis of locally advanced esophageal cancer is poor. The greatest prognostic factor of locally advanced esophageal cancer is a local control. We experienced a case of T4 locally advanced thoracic esophageal cancer who was successfully resected without any combined resection after multimodality therapy. A male in 75-year-old. was diagnosed with type 3 locally advanced upper thoracic esophageal cancer whose metastatic right recurrent laryngeal lymph node invaded into the trachea. Definitive chemoradiation therapy(CRT)was performed, leading to a significant shrinkage of the main tumor, but T4 lesion remained. Next, adding DCF therapy(docetaxel, CDDP and 5-FU), a relief of T4 was finally obtained. Then, salvage surgery with subtotalesophagectomy and retrosternalesophagealreconstruction with gastric tube was performed, resulting in R0 resection without any combined resection. The postoperative course was uneventful, and the patient has been alive without recurrence for 1 year after surgery. In locally advanced cancer, focusing on T4 downstaging, it is significantly important in terms of safety, curativity and organ preservation to perform surgery after a sure sign of T4 relief by multimodality therapy.

    2011-09-01

    To discuss the important technological advances that have taken place in the planning and delivery of both external beam radiotherapy and brachytherapy for patients with locally advanced cervical cancer, and the implications for improved clinical outcomes. Technological advances in external beam radiation treatment and brachytherapy for patients with cervical cancer allow more precise targeting of tumour and relative sparing of surrounding normal organs and tissues. Early evidence is emerging to indicate that these advances will translate into improvements in tumour control and reduced side effects. However, there are patient, tumour and treatment-related factors that can detract from these benefits. Foremost among these is complex, unpredictable and sometimes dramatic internal tumour and normal organ motion during treatment. The focus of current research and clinical development is on tracking internal anatomic change in individual patients and adapting treatment plans as required to assure that optimal tumour coverage and normal tissue sparing is maintained at all times. The success of this approach will depend on clear definitions of target volumes, high resolution daily soft tissue imaging, and new software tools for rapid contouring, treatment planning and quality assurance. Radiation treatment of locally advanced cervical cancer is evolving rapidly, driven by advances in technology, towards more individualized patient care that has the potential to substantially improve clinical outcomes.

    Dramatic improvements in the outcomes of patients with rectal cancer have occurred over the past 30 years. Advances in surgical pathology, refinements in surgical techniques and instrumentation, new imaging modalities, and the widespread use of neoadjuvant therapy have all contributed to these improvements. Several questions emerge as we learn of the benefits or lack thereof for components of the current multimodality treatment in subgroups of patients with nonmetastatic locally advanced rectal cancer (LARC). What is the optimal surgical technique for distal rectal cancers? Do all patients need postoperative chemotherapy? Do all patients need radiation? Do all patients need surgery, or is a nonoperative, organ-preserving approach warranted in selected patients? Answering these questions will lead to more precise treatment regimens, based on patient and tumor characteristics, that will improve outcomes while preserving quality of life. However, the idea of shifting the treatment paradigm (chemoradiotherapy, total mesorectal excision, and adjuvant therapy) currently applied to all patients with LARC to a more individually tailored approach is controversial. The paradigm shift toward organ preservation in highly selected patients whose tumors demonstrate clinical complete response to neoadjuvant treatment is also controversial. Herein, we highlight many of the advances and resultant controversies that are likely to dominate the research agenda for LARC in the modern era. PMID:25918296

    External laryngeal trauma is a rare but potentially life-threatening situation in the acutely injured patient. Trauma mechanism and magnitude, maximum focus of the applied force, and patient related factors, such as age and ossification of the laryngeal cartilages influence the spectrum of observed injuries. Their correct diagnosis and prompt management are paramount in order to avoid patient death or long-term impairment of breathing, swallowing and speaking. The current review provides a comprehensive approach to the radiologic interpretation of imaging studies performed in patients with suspected laryngeal injury. It describes the key anatomic structures that are relevant in laryngeal trauma and discusses the clinical role of multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI) in the acute emergency situation. The added value of two-dimensional multiplanar reconstructions (2D MPR), three-dimensional volume rendering (3D VR) and virtual endoscopy (VE) for the non-invasive evaluation of laryngeal injuries and for treatment planning is discussed. The clinical presentation, biomechanics of injury, diagnostic pitfalls and pearls, common and uncommon findings are reviewed with emphasis of fracture patterns, involvement of laryngeal joints, intra- and extralaryngeal soft tissue injuries, and complications seen in the acute emergency situation. The radiologic appearance of common and less common long-term sequelae, as well as treatment options are equally addressed

    Laryngeal Adductor Reflex Background: A rapid closure of the vocal folds is necessary, whenever foreign materials or food particles penetrate into the larynx. Otherwise a passage of these particles into the trachea or the lower respiratory tract would be imminent. An aspiration could mechanically block the respiratory tract and cause severe dyspnoea or cause aspiration pneumonia. For this systematic review a selective literature research in PubMed and Scopus using the keywords "laryngeal adductor reflex" and "vocal fold closure" has been carried out. Apart from the oesophago-glottal and pharyngo-glottal closure reflexes, the laryngeal adductor reflex (LAR) has been investigated in particular. The LAR qualifies as a reflectory laryngeal adductor mechanism and involves early, presumably di- or oligosynaptic ipsilateral LAR1 as well as late polysynaptic ipsi- and contralateral LAR2 components. In clinical routine diagnostic settings of dysphagia, LAR is only assessed qualitatively and usually triggered by air pulses or tactile stimulation. Dysphagiologists often find that not only the laryngeal sensibility in general is impaired, but especially the protective laryngeal adduction mechanism, which results in a higher risk of aspiration. Thus, it appears mandatory to test the LAR not only qualitatively but also quantitatively. Unfortunately a valid and reliable method that can be employed in clinical practice has not yet been put forward. © Georg Thieme Verlag KG Stuttgart · New York.

    When radiation therapy is used for palliation of obstruction in patients with advanced esophageal carcinoma, an improvement in dysphagia can be expected in approximately 50% of patients. Major objective responses have rarely been quantitied but, in one study, were seen in 33% patients. Recurrence of dysphagia is usually seen within 2-6 months of treatment. Radiation toxicities and complications, even when used with palliative intent, can be substantial and include esophagitis, tracheoesophageal or esophageal-aortic fistula, mediastinitis, hemorrhage, pneumonitis, and myelosuppression

    2013-01-01

    Purpose: To investigate interfraction setup variations of the primary tumor, elective nodes, and vertebrae in laryngeal cancer patients and to validate protocols for cone beam computed tomography (CBCT)-guided correction. Methods and Materials: For 30 patients, CBCT-measured displacements in fractionated treatments were used to investigate population setup errors and to simulate residual setup errors for the no action level (NAL) offline protocol, the extended NAL (eNAL) protocol, and daily CBCT acquisition with online analysis and repositioning. Results: Without corrections, 12 of 26 patients treated with radical radiation therapy would have experienced a gradual change (time trend) in primary tumor setup ≥4 mm in the craniocaudal (CC) direction during the fractionated treatment (11/12 in caudal direction, maximum 11 mm). Due to these trends, correction of primary tumor displacements with NAL resulted in large residual CC errors (required margin 6.7 mm). With the weekly correction vector adjustments in eNAL, the trends could be largely compensated (CC margin 3.5 mm). Correlation between movements of the primary and nodal clinical target volumes (CTVs) in the CC direction was poor (r 2 =0.15). Therefore, even with online setup corrections of the primary CTV, the required CC margin for the nodal CTV was as large as 6.8 mm. Also for the vertebrae, large time trends were observed for some patients. Because of poor CC correlation (r 2 =0.19) between displacements of the primary CTV and the vertebrae, even with daily online repositioning of the vertebrae, the required CC margin around the primary CTV was 6.9 mm. Conclusions: Laryngeal cancer patients showed substantial interfraction setup variations, including large time trends, and poor CC correlation between primary tumor displacements and motion of the nodes and vertebrae (internal tumor motion). These trends and nonrigid anatomy variations have to be considered in the choice of setup verification protocol and

    In human cancers, podoplanin expression and its correlation with tumour invasive potential raise its possible role as a diagnostic and prognostic marker for cancer. To investigate the immunohistochemical expression of podoplanin in laryngeal Squamous Cell Carcinoma (SCC) and dysplasia. This study included a total of 60 archived, formalin fixed, paraffin embedded tissue blocks of 40 cases of laryngeal SCC and 20 cases of dysplastic lesions. The samples were immunohistochemically analysed for podoplanin expression. Podoplanin expression was significantly higher in laryngeal SCC (90%) than laryngeal dysplastic lesions (55%) (p-value=0.002). The expression of podoplanin was significantly increased with the higher grades of dysplasia (p-value=0.016). A significant positive correlation was detected between podoplanin expression in laryngeal SCC and depth of tumour invasion (p-value=0.035), and stage (p-value=0.026). The high expression of podoplanin in laryngeal SCC and its significant correlation with poor prognostic parameters recommends podoplanin as a prognostic marker in laryngeal SCC. In addition, increased podoplanin expression with higher grades of dysplasia, supports its role in malignant transformation and allows us to recommend its evaluation in premalignant lesions.

    1999-01-01

    Purpose: To determine if pre-radiotherapy (RT) and/or post-radiotherapy computed tomography (CT) can predict local failure in patients with laryngeal carcinoma treated with definitive RT. Methods and Materials: The pre- and post-RT CT examinations of 59 patients (T3 glottic carcinoma [n = 30] and T1-T4 supraglottic carcinoma [n = 29]) were reviewed. For each patient, the first post-RT CT study between 1 and 6 months after irradiation was used. All patients were treated with definitive hyperfractionated twice-daily continuous-course irradiation to a total dose of 6,720-7,920 cGy, and followed-up clinically for at least 2 years after completion of RT. Local control was defined as absence of primary tumor recurrence and a functioning larynx. On the pre-treatment CT study, each tumor was assigned a high-or low-risk profile for local failure after RT. The post-RT CT examinations were evaluated for post-treatment changes using a three-point post-RT CT-score: 1 = expected post-RT changes; 2 = focal mass with a maximal diameter of 1 cm, or < 50% estimated tumor volume reduction. Results: The local control rates at 2 years post-RT based on pre-treatment CT evaluation were 88% for low pre-treatment risk profile patients (95% CI: 66-96%) and 34% (95% CI: 19-50%) for high pre-treatment risk profile patients (risk ratio 6.583; 95% CI: 2.265-9.129; p = 0.0001). Based on post-treatment CT, the local control rates at 2 years post-RT were 94% for score 1, 67% for score 2, and 10% for score 3 (risk ratio 4.760; 95% CI: 2.278-9.950 p 0.0001). Post-RT CT scores added significant information to the pre-treatment risk profiles on prognosis. Conclusions: Pre-treatment CT risk profiles, as well as post-RT CT evaluation can identify patients, irradiated for laryngeal carcinomas, at high risk for developing local failure. When the post-RT CT score is available, it proves to be an even better prognosticator than the pre-treatment CT-risk profile

    Laryngeal papilloma is one of the most common non-malignant tumors of the larynx. In adult they are included to pre-cancerous diseases. In morphological examination, it is a solid tumor. Often it is possible to cure them during one surgical procedure. The disease is mostly localized on the anterior commissurae region, vocal fold, ventricules, and on the laryngeal surface of the epiglottis. If the malignant transformation is suspected, a large excision with margin has to be performed, completed by a histological evaluation. A case of a huge laryngeal papilloma with dyspnea is presented.

    Purpose: Radiotherapy (RT) combined with cisplatin or cetuximab is the standard of care for patients with locally advanced head/neck cancer (LA-HNC). The feasibility of radiochemotherapy with cisplatin and cetuximab, supported with amifostine, was herein investigated. Methods and Materials: Forty-three patients with LA-HNC were recruited. Conformal hypofractionated/accelerated RT with amifostine cytoprotection (2.7 Gy/fraction, 21 fractions in 4 weeks) was combined with cisplatin (30 mg/m 2 /week) and cetuximab (standard weekly regimen) therapy. The dose of amifostine was individualized according to tolerance. Results: A high daily amifostine dose (750-1,000 mg) was tolerated by 41.8% of patients, and a standard dose (500 mg) was tolerated by 34.9% of patients. A high amifostine dose was linked to reduced RT delays (p = 0.0003). Grade 3 to 4 (3-4) mucositis occurred in 7/43 (16.2%) patients, and fungal infections occurred in 18/43 (41.8%) patients. Radiation dermatitis was not aggravated. Interruption of cetuximab due to acneiform rash was necessary in 23.3% of patients, while amifostine-related fever and rash were not observed. Severe late radiation sequelae consisted of laryngeal edema (9% laryngeal cases) and cervical strictures (33% of hypopharyngeal cases). Good salivary function was preserved in 6/11 (54.5%) nasopharyngeal cancer patients. The complete response rate was 68.5%, reaching 77.2% in patients with minor radiotherapy delays. The 24-month local control and survival rates were 72.3% and 91%, respectively (median follow-up was 13 months.). Conclusions: In this feasibility study, weekly administration of cisplatin and cetuximab was safely combined with accelerated RT, supported with amifostine, at the cost of a high incidence of acneiform rash but a reduced incidence of amifostine-related fever/rash. A high daily dose of amifostine allows completion of therapy with minor delays.

    The term vocal fold nodules refers to bilateral thickening of the membranous folds with minimal impairment of the vibratory properties of the mucosa. Nodules are thought to be related to repetitive mechanical stress, associated with voice use patterns. Diagnosis is typically made in the office via either rigid or flexible laryngeal stroboscopy. Depending on the individual child, obtaining an optimal view of the larynx can be difficult if not impossible. Recent advances in high-frequency ultrasonography allows for transcervical examination of laryngeal structures. The goal of this project was to determine if laryngeal ultrasound (LUS) can be used to identify vocal fold nodules in dysphonic children. Prospective case-control study in which the patient acted as his or her own control. Forty-six pediatric patients were recruited for participation in this study; the mean age was 4.8 years. Twenty-three did not have any vocal fold lesions and 23 had a diagnosis of vocal fold nodules on laryngeal stroboscopy. Recorded LUSs were reviewed by two pediatric radiologists who were blinded to the nodule status. There was substantial inter-rater agreement (κ = 0.70, 95% confidence interval [CI]: 0.50-0.89) between the two radiologists regarding the presence of nodules. There was also substantial agreement (κ = 0.87, 95% CI: 0.72-1) between LUS and laryngeal stroboscopy. Sensitivity of LUS was 100% (95% CI: 85%-100%) and specificity was 87% (95% CI: 66%-97%). LUS can be used to identify vocal fold nodules in children with substantial agreement with laryngeal stroboscopy. 3b Laryngoscope, 127:676-678, 2017. © 2016 The American Laryngological, Rhinological and Otological Society, Inc.

    is therefore of great importance. In the first part of this review, we present current strategies in the drug delivery field, focusing on site-specific triggered drug release from liposomes in cancerous tissue. Currently marketed drug delivery systems lack the ability to actively release the carried drug......, none of them have yet led to marketed drugs and are still far from achieving this goal. The most advanced and prospective technologies are probably the prodrug strategies where nontoxic drugs are carried and activated specifically in the malignant tissue by overexpressed enzymes. In the second part......Tumor specific drug delivery has become increasingly interesting in cancer therapy, as the use of chemotherapeutics is often limited due to severe side effects. Conventional drug delivery systems have shown low efficiency and a continuous search for more advanced drug delivery principles...

    Patients with advanced lung cancers have bad prognosis and, many times, are submitted to prolonged and not always efficient treatments. We present a study where 51 patients were treated with hypo fractionated radiotherapy, based on two distinct schemes, according to the performance status and social conditions of each patient: continuous treatment: 30 Gy, 10 fractions of 3 Gy, 5 days/week (37 cases); weekly treatment: 30 Gy, 6 fractions of 5 Gy, once a week (14 cases). Symptoms relief and impact in survival were evaluated. In both groups, we observed improvement of symptoms in about 70% of the occurrences with a medium survival of three months. We conclude that hypo fractionation is an effective palliative treatment for lung cancers, in patients with short life-expectancy and must be considered as a option in advanced cases, in patients with short life-expectancy that deserve some kind of treatment.

    Full Text Available Negative emotions (distress are recognized as part of the psychological profile of patients diagnosed with advanced stage cancer. However, most patients are not accustomed to verbalize feelings towards their physician, and generally towards family and medical care personnel. The purpose of this paper is to analyze the expression of emotions by patients in advanced stages of cancer, respectively the means by which they get to express emotions. To this respect, we identified the most common types of emotions expressed, or metaphors used by patients to describe their emotions and topics that trigger emotions. Words and phrases most commonly used are in relation to: fear, anxiety, depression, guilt, negligence, concern. They are uttered in order to depict the network created between disclosed emotions and topics on health status, symptoms, adverse effects and therapeutic choice, patient privacy, and social and family issues.

    This study was conducted to evaluate quality of life (QOL) and functional outcome in patients with carcinomas of the larynx and hypopharynx treated with accelerated radiotherapy (RT). Between January 1991 and September 1996, 21 patients treated with accelerated concomitant boost RT schedule (69.9 Gy in 5. 5 weeks) for laryngeal (n = 10) or hypopharyngeal (n = 11) carcinomas and who remained free of disease at 1-year minimum follow-up were evaluated. The functional outcome was assessed by the subjective Performance Status Scale for Head and Neck cancer (PSSHN) and general QOL by the European Organization for Research and Treatment of Cancer Core QOL questionnaire (EORTC QLQ-C30). The median length of follow-up was 37 months (range, 13 to 75). The PSSHN scores were 89, 84, and 86, respectively, for eating in public, understandability of speech and normalcy of diet (100 = normal function). Significantly lower scores for understandability of speech were observed in patients with advanced and laryngeal carcinomas. Normalcy of diet was affected negatively by the severity of xerostomia. All mean functional scale scores of the EORTC QLQ-C30 module were 20% to 25% below the higher score. Most of these scale scores were significantly affected by the severity of xerostomia. Patients treated with concomitant boost RT for laryngeal and hypopharyngeal carcinomas appear to have similar QOL and functional outcome to those reported for patients treated with conventional or hyperfractionated RT. As expected, many QOL scales were affected by the severity of xero- stomia.

    Objective: To describe the experience at the National Cancer Institute (NCI) on the use of neoadjuvant chemotherapy as primary treatment for epithelial ovarian cancer among patients in stages IIIC and IV. Methods: We conducted a descriptive retrospective study (case series type) of patients diagnosed with epithelial ovarian cancer in stages IIIC and IV, treated at the NCI from January 1, 2003 to December 31,2006, who underwent neoadjuvant chemotherapy as primary treatment. Demographic characteristics and clinical outcomes are described. Results: Seventeen patients who fulfilled the above mentioned criteria were selected. Once neoadjuvant chemotherapy ended, 5 patients (29.4%) achieved complete or partial clinical response; 4 (23.8%) remained in stable condition, and 8 (47.6%) showed signs of progressive illness. Interval debulking surgery was performed on objective response patients. Maximum cytoreduction was achieved in 5 patients (100%); first relapse was reported at month 18 of follow-up; 2 disease-free survivors were identified in December, 2007; 8 (49%) reported some degree of non-severe chemotherapy-related toxicity. No mortality was related to chemotherapy, no post surgical complications were observed and no patient required advanced support management. Conclusions: Neoadjuvant chemotherapy, followed by optimal interval debulking surgery among selected patients, can be an alternative treatment for advanced epithelial ovarian cancer among women with irresecability or the critically ill. Further studies with improved design are required to confirm these findings.

    Full Text Available RF Kokelaar, MD Evans, M Davies, DA Harris, J Beynon Department of Colorectal Surgery, Singleton Hospital, Swansea, UK Abstract: Between 5% and 10% of patients with rectal cancer present with locally advanced rectal cancer (LARC, and 10% of rectal cancers recur after surgery, of which half are limited to locoregional disease only (locally recurrent rectal cancer. Exenterative surgery offers the best long-term outcomes for patients with LARC and locally recurrent rectal cancer so long as a complete (R0 resection is achieved. Accurate preoperative multimodal staging is crucial in assessing the potential operability of advanced rectal tumors, and resectability may be enhanced with neoadjuvant therapies. Unfortunately, surgical options are limited when the tumor involves the lateral pelvic sidewall or high sacrum due to the technical challenges of achieving histological clearance, and must be balanced against the high morbidity associated with resection of the bony pelvis and significant lymphovascular structures. This group of patients is usually treated palliatively and subsequently survival is poor, which has led surgeons to seek innovative new solutions, as well as revisit previously discarded radical approaches. A small number of centers are pioneering new techniques for resection of beyond-total mesorectal excision tumors, including en bloc resections of the sciatic notch and composite resections of the first two sacral vertebrae. Despite limited experience, these new techniques offer the potential for radical treatment of previously inoperable tumors. This narrative review sets out the challenges facing the management of LARCs and discusses evolving management options. Keywords: rectal cancer, exenteration, pelvic sidewall, sacrectomy

    2017-12-01

    Objective Laryngeal cysts may occur at any mucosa-lined location within the larynx and account for 5% to 10% of nonmalignant laryngeal lesions. A number of proposed classifications for laryngeal cysts exist; however, no previously published classification aims to guide management. This review analyzes contemporary laryngeal cyst management and proposes a framework for the terminology and management of cystic lesions in the larynx. Data Sources PubMed/Medline. Review Methods A primary literature search of the entire Medline database was performed for all titles of publications pertaining to laryngeal cysts and reviewed for relevance. Full manuscripts were reviewed per the relevance of their titles and abstracts, and selection into this review was according to their clinical and scientific relevance. Conclusion Laryngeal cysts have been associated with rapid-onset epiglottitis, dyspnea, stridor, and death; therefore, they should not be considered of little significance. Symptoms are varied and nonspecific. Laryngoscopy is the primary initial diagnostic tool. Cross-sectional imaging may be required, and future use of endolaryngeal ultrasound and optical coherence tomography may revolutionize practice. Where possible, cysts should be completely excised, and there is growing evidence that a transoral approach is superior to transcervical excision for nearly all cysts. Histology provides definitive diagnosis, and oncocytic cysts require close follow-up. Implications for Practice A new classification system is proposed that increases clarity in terminology, with the aim of better preparing surgeons and authors for future advances in the understanding and management of laryngeal cysts.

    Full Text Available OBJETIVO: Os tipos de câncer de pulmão, laringe e esôfago têm como um de seus principais fatores de risco o fumo. O objetivo do estudo foi avaliar o risco populacional atribuível ao fumo nesses tipos de câncer. MÉTODOS: A pesquisa baseou-se em três estudos de caso-controle em cidade de médio porte do Brasil. Analisaram-se casos incidentes hospitalares de câncer de pulmão, de laringe e de esôfago diagnosticados por biópsias; os controles foram pacientes hospitalizados por outros motivos, sem ser câncer ou doenças altamente relacionadas ao fumo. O fator de exposição foi o tabagismo medido em três níveis: não-fumantes, ex-fumantes e fumantes atuais, definidos por meio de questionários aplicados por entrevistadores treinados. Para a medida de efeito, foi utilizado o odds ratio obtendo-se, dessa forma, o "risco populacional atribuível" ao fumo com IC de 95%. RESULTADOS: Foram estudados 122 casos e 244 controles de câncer de pulmão, 50 casos de câncer de laringe e 48 casos de câncer de esôfago, com um grupo de 96 controles comum a ambos. A prevalência da exposição ao fumo utilizada para a análise foi de 34%, que corresponde à prevalência de fumo na população adulta da cidade. Os odds ratios para o cálculo do risco populacional atribuível foram obtidos por análises ajustadas para os fatores de confusão de cada um dos estudos. Para ex-fumantes com câncer de pulmão, o risco populacional atribuível foi de 63% (IC95%, 0,58-0,68 e, para fumantes, de 71% (IC95%, 0,65-0,77. Para câncer de laringe, o RPA foi de 74% (IC95%, 0,70-0,78 para ex-fumantes e de 86% (IC95%, 0,81-0,85 para fumantes. O câncer de esôfago mostrou um risco de 54% (IC95%, 0,46-0,62 para fumantes. CONCLUSÃO: Conclui-se que o fumo é um importante fator de risco e que a cessação do mesmo contribuiria para reduções significativas na incidência de câncer nesses três sítios.OBJECTIVE:Lung, laryngeal and esophageal cancers have smoking as one

    Laryngeal cancer is the second most frequent head and neck cancer in the Brazilian male population. For treatment, radiotherapy combined with chemotherapy is now used in substitution for total laryngectomy, becoming the standard treatment for advanced larynx cancer cases, with the aim of organ preservation. However, this method needs assessment of the side effects caused to normal tissue and organ functionality after treatment and the relation of these clinical factors to the individual characteristics of patients. Thus, the clinical characteristics of 229 patients with laryngeal cancer treated with radiotherapy were evaluated by medical records analysis in relation to normal tissue radiosensibility. Significant relations between smoking (p = 0.018) and combined chemoradiotherapy assistance (p = 0.03) were identified with high frequency of treatment suspension cases. The application of combined chemoradiotherapy also resulted in a higher incidence of oral mucositis (p = 0.04), xerostomia (p = 0.001) and treatment side effects to GIT (p = 0.04). Advanced clinical staging was associated with worse prognosis (p = 0.002) and a higher occurrence of treatment failure (p < 0.001). Radiotherapy was also less effective depending on the primary tumor location (p = 0.001). (author)

    The limitations of surgical treatment for advanced esophageal cancer have been clarified, although esophagectomy with extended lymph node dissection has been widespread in Japan. Preoperative adjuvant therapy has been investigated in Western countries, and recently preoperative chemoradiotherapy (CRT) has been introduced for the treatment of resectable esophageal cancer. There are several reports of randomized controlled trials (RCTs) comparing CRT followed by surgery and surgery alone. According to the results of a meta-analysis, preoperative CRT is considered to be the standard therapy in Western countries. However, problems in the clinical heterogeneity of meta-analyses include: small number of patients in each RCT; differences in stage grouping; presence of both squamous cell carcinoma and adenocarcinoma; various surgical techniques used; and differences in the amount of radiation administered. Preoperative CRT appears to be a promising method for the treatment of potentially resectable advanced esophageal cancer patients with nodal metastasis. Currently, phase I and II trials of new anticancer agents or molecular targeting agents are ongoing. However, since the surgical procedure in the Western method is still being debated, well-designed RCTs are necessary, especially in esophageal squamous cell carcinoma. The effectiveness of CRT followed by surgery should be clarified based on excellent Japanese surgical techniques. (author)

    Human head and neck cancer disease is the most common respiratory cancer that population suffering from its symptoms all over the world. This type of malignancy is connected with drinking alcohol and smoking tobacco beside other factors concerning the type of nutrition, age, gender as well as environmental factors such as ionizing radiation and toxic chemicals. These factors can lead to genetic changes in one or more tissue cells which begin to proliferate due to the inflammatory stimulus. The immune inflammatory state serves as a key mediator of the middle stages of tumor development. Cancer begins with a series of genetic changes that prompt group of cells which begin to over replicate and then invade surrounding tissues (metastases) and lately the malignancy spread to the blood and lymph nodes. Genetic changes which cause cancer can be considered as the match that lights the fire and the inflammation is the fuel that feed it. The antiinflammatory cancer therapy will prevent the premalignant cells from turning fully to cancerous or it will impede an existing tumor from spreading to other sites in the body. Chronic inflammation can play an important role in the progression of some types of tumors. So there is a close link between tumor and inflammation

    BACKGROUND: Merkel cell cancer (MCC) is an uncommon neuroendocrine skin cancer occurring predominantly in elderly Caucasians. It tends to metastasize to regional lymph nodes and viscera and is sensitive to chemotherapy but recurs rapidly. AIM: To report one such case, its response to chemotherapy and briefly review the literature. METHODS: A 73-year-old male with a fungating primary lesion on his left knee and ulcerated inguinal lymph nodes was diagnosed with MCC and treated with chemotherapy. The two largest case series and reviews of case reports were summarised. RESULTS: His ulcer healed after two cycles of carboplatin and etoposide with improvement in quality of life. Overall response rates of nearly 60% to chemotherapy are reported but median survival is only nine months with metastatic disease. CONCLUSIONS: Chemotherapy should be considered for fit elderly patients with MCC who have recurrent or advanced disease.

    Previous work suggests that parents of children with cancer can remain hopeful despite receiving prognostic information, but we know little about what hope means to such parents, or the extent to which parents can feel hopeful even while facing the child's impending death. We audiotaped conversations between clinicians and parents of 32 children with relapsed or refractory cancer, and then interviewed parents about their hopes and expectations for their child. Parent statements about prognosis in interviews mirrored those made by clinicians during discussions about the child's diagnosis with refractory or relapsed cancer. Clinicians used language referring to hope during these conversations but did not ask parents directly about their hopes. Parents expressed a range of hopes for their children, from hopes related to cure or treatment response, to quality of life, normalcy, and love and relationships for the child. For most parents, expectations about prognosis were not aligned with their hopes for the child; for example, many parents hoped for a cure and also reported that they did not believe cure was possible. Many parents were able to acknowledge this incongruence. Parents accurately conveyed the reality of their child's serious condition in the setting of advanced cancer, and yet maintained hope. Hopes were not limited to hope for cure/treatment response. Clinicians should be encouraged to engage in direct conversations about hope with parents as a means to elicit realistic hopes that can help to focus the most meaningful plans for the child and family.

    Background and purpose: To compare in a phase III study the loco-regional control, disease-free survival and overall survival induced by an accelerated regimen (AF) as compared with conventional regimen (CF) and to analyze the early and late post-radiation morbidity in both arms. Materials and methods: Patients with age≤75, WHO 0-1, suitable for a radical course of radiotherapy T1-T3, N0, M0, stage of glottic and supraglottic laryngeal cancer were randomized to either CF: 66Gy given in 33 fractions over 45 days or AF: 66Gy given in 33 fractions over 38 days (2 fractions every Thursday). A total of 395 patients were included from 05.1995 to 12.1998. Results. Early toxicity: At the end of radiotherapy patients treated with AF complained for more severe reactions than patients treated with CF. In 8 weeks after treatment completion patients treated with AF complained only for more severe pain on swallowing (P=0.027). In 4 months after treatment completion all types of toxicity except for skin teleangiectasia (P=0.001) were similar in the two groups. Loco-regional control: comparison between CF and AF showed no difference in terms of loco-regional control (P=0.37). Conclusions: The improvement in AF in terms of loco-regional control is estimated to be 3-5% in comparison with conventional regimen and is not significant. The intensity of reactions after 4 months was similar in both arms, what suggests the possibility of further shortening of the overall time by few days or enhancing the total dose within the limits of acceptable morbidity

    Full Text Available Abstract Background Concurrent platinum-based radiochemotherapy has been recommended as a standard of care in patients with locally advanced squamous cell head and neck carcinomas. Unfortunately, there is a lack of level one evidence on best treatment approach for advanced hypopharyngeal cancer. This report aims to summarize the results of our study on concurrent radiochemotherapy in patients with advanced hypopharyngeal cancer. Methods A retrospective analysis of 41 patients with stage III-IV hypopharyngeal cancer was performed. All patients were treated with three dimensional conformal radiotherapy and received 70 Gy in 35 fractions (2 Gy per fraction, 5 fractions per week. In dependence of the period when radiotherapy was realized, two different treatment techniques were used. Concurrent chemotherapy consisted of cisplatin 30 mg/m2 given on a weekly basis. Results The median age was 52 years (range 29-70. Stage IV disease was recognized in 73.2% of the patients. Complete response rates at the primary site and at the metastatic neck lymph nodes were 68.3% and 36.6%, respectively. A complete composite response was present in 27 patients (65.9%. Median follow-up was 13 months (range 7-36. Distant metastases as initial failure occurred in 7 patients (46.7%. The 2-year local relapse-free survival and regional relapse-free survival rates were 55.2% and 75.8%, respectively. The 2-year locoregional relapse-free survival rate was 51.3%. The 2-year disease-free survival and overall survival rates were 29.3% and 32.8%, respectively. Confluent mucositis was developed in 46.3% of patients. Leucopenia grade 1 was the most frequent hematological toxicity. The median weight loss at the end of treatment was 12% (range 5-21. The worst grade of late toxicity was most commonly pronounced in the skin and in the subcutaneous tissue. Conclusions Based on unsatisfactory results in our study we suggest that the use of sequential radiochemotherapy or chemotherapy

    Metallothioneins (MTs) are low molecular weight, cysteine-rich heavy metal-binding proteins which participate in the mechanisms of Zn homeostasis, and protect against toxic metals. MTs contain metal-thiolate cluster groups and suppress metal toxicity by binding to them. The aim of this study was to determine the − 5 A/G (rs28366003) single-nucleotide polymorphism (SNP) in the core promoter region of the MT2A gene and to investigate its effect on allele-specific gene expression and Cd, Zn and Cu content in squamous cell laryngeal cancer (SCC) and non-cancerous laryngeal mucosa (NCM) as a control. The MT2A promoter region − 5 A/G SNP was determined by restriction fragment length polymorphism using 323 SCC and 116 NCM. MT2A gene analysis was performed by quantitative real-time PCR. The frequency of A allele carriage was 94.2% and 91.8% in SCC and NCM, respectively, while G allele carriage was detected in 5.8% and 8.2% of SCC and NCM samples, respectively. As a result, a significant association was identified between the − 5 A/G SNP in the MT2A gene with mRNA expression in both groups. Metal levels were analyzed by flame atomic absorption spectrometry. The significant differences were identified between A/A and both the A/G and G/G genotypes, with regard to the concentration of the contaminating metal. The Spearman rank correlation results showed that the MT2A expression and Cd, Zn, Cu levels were negatively correlated. Results obtained in this study suggest that − 5 A/G SNP in MT2A gene may have an effect on allele-specific gene expression and accumulation of metal levels in laryngeal cancer. - Highlights: • MT2A gene expression and metal content in laryngeal cancer tissues • Association between SNP (rs28366003) and expression of MT2A • Significant associations between the SNP and Cd, Zn and Cu levels • Negative correlation between MT2A gene expression and Cd, Zn and Cu levels.

    Apoptosis in peripheral blood lymphocytes of healthy donors and cancer patients after γ-radiation with different doses is studied by the flow cytometry method. Wide intra- and interindividual variabilities of the lymphocyte radiosensitivity by different donors are observed. The radiosensitivity does not depend on the subpopulation composition of the lymphocyte pool. The persons with very low and high lymphocyte radiosensitivities are found significantly more often among the cancer patients than among the healthy donors. One can suggest that this method is useful to define risk groups with regard to radiogenic neoplasms and prognosis of radiotherapy efficiency [ru

    Preoperative concurrent chemoradiation therapy with 5-fluorouracil and cisplatin was applied for advanced rectal cancer. Eligible criteria were as follows: no previous treatment, more than hemicircular occupation, T 3 or more, invasion to adjacent organs or lymph node metastasis on CT scan, tumor fixation by digital examination. Eleven patients were enrolled with this regimen consisting of 5-FU; 500 mg/day x 5/w x 4, CDDP; 10 mg/day x 5/w x 4 and radiation; 2 Gy x 5/w x 4. As a toxicity, grade 2 leukopenia in 2 cases, grade 2 GI symptoms in one case and radiation dermatitis was observed in 8 cases. As a local response, there were PR in 10 cases and NC in 1 case. Surgical resection was performed on 8 patients. Histological responses in the resected specimens were grade 2, 5 cases; grade 1b, 1 case; and grade 1a, 2 cases. Operative radicalities were grade A, 3 cases; grade B, 3 cases; and grade C, 2 cases. Preoperative chemoradiation is one of the effective options in multimodal treatment for advanced rectal cancer.

    2018-01-01

    The main clinical challenge in the management of thyroid cancer is to avoid over-treatment and over-diagnosis in patients with lower-risk disease while promptly identifying those patients with more advanced or high-risk disease requiring aggressive treatment. In recent years, novel clinical and molecular data have emerged, allowing the development of new staging systems, predictive and prognostic tools, and treatment approaches. There has been a notable shift toward more conservative management of low- and intermediate-risk patients, characterized by less extensive surgery, more selective use of radioisotopes (for both diagnostic and therapeutic purposes), and less intensive follow-up. Furthermore, the histologic classification; tumor, node, and metastasis (TNM) staging; and American Thyroid Association risk stratification systems have been refined, and this has increased the number of patients in the low- and intermediate-risk categories. There is now a need for new, prospective data to clarify how these changing practices will impact long-term outcomes of patients with thyroid cancer, and new follow-up strategies and biomarkers are still under investigation. On the other hand, patients with more advanced or high-risk disease have a broader portfolio of options in terms of treatments and therapeutic agents, including multitarget tyrosine kinase inhibitors, more selective BRAF or MEK inhibitors, combination therapies, and immunotherapy.

    Full Text Available Importance. Laryngeal cancer infrequently results in distant metastases, but metastasis to skeletal muscle is extremely uncommon. Observations. A 55-year-old male presenting with progressive dyspnea and hoarseness was found to have Stage IVA T4aN2cM0 laryngeal cancer and eventually underwent total laryngectomy. Before the patient could be started on adjuvant chemoradiation, the patient developed masses on both thighs. Biopsy revealed metastatic squamous cell carcinoma consistent with the primary laryngeal cancer. He was offered palliative chemotherapy; however, he developed new soft tissue masses to the left of his stoma and in the prevertebral area one week later. He also had new cervical and supraclavicular nodes and a pathological compression fracture of L3. Patient died within 4 months of diagnosis. Conclusions. Distant metastasis such as skeletal metastasis portends a poor prognosis. Further studies are required to determine the best course of treatment in these patients.

    To examine toxicity and outcomes for patients treated with preoperative chemoradiotherapy (CRT) for gastric cancer. Patients with gastroesophageal (GE) junction (Siewert type II and III) or gastric adenocarcinoma who underwent neoadjuvant CRT followed by planned surgical resection at Duke University between 1987 and 2009 were reviewed. Overall survival (OS), local control (LC) and disease-free survival (DFS) were estimated using the Kaplan-Meier method. Toxicity was graded according to the Common Toxicity Criteria for Adverse Events version 4.0. Forty-eight patients were included. Most (73%) had proximal (GE junction, cardia and fundus) tumors. Median radiation therapy dose was 45 Gy. All patients received concurrent chemotherapy. Thirty-six patients (75%) underwent surgery. Pathologic complete response and R0 resection rates were 19% and 86%, respectively. Thirty-day surgical mortality was 6%. At 42 months median follow-up, 3-year actuarial OS was 40%. For patients undergoing surgery, 3-year OS, LC and DFS were 50%, 73% and 41%, respectively. Preoperative CRT for gastric cancer is well tolerated with acceptable rates of perioperative morbidity and mortality. In this patient cohort with primarily advanced disease, OS, LC and DFS rates in resected patients are comparable to similarly staged, adjuvantly treated patients in randomized trials. Further study comparing neoadjuvant CRT to standard treatment approaches for gastric cancer is indicated

    The objective of the study was to evaluate the association between changes in laryngeal sensation and initiation of swallowing reflex or swallowing function before and after (chemo)radiotherapy. A prospective study was conducted in a tertiary referral university hospital. Thirteen patients who received (chemo)radiotherapy for treatment of laryngeal or hypopharyngeal cancer were included. Laryngeal sensation was evaluated at the tip of the epiglottis before and 1, 3 months, and 1 year after (chemo)radiotherapy. Videofluoroscopy was performed at the same time. Quantitative determinations included changes in laryngeal sensation, computed analysis of pharyngeal delay time, the distance and velocity of hyoid bone movement during the phase of hyoid excursion, and pharyngeal residue rate (the proportion of the bolus that was left as residue in the pharynx at the first swallow). Laryngeal sensation significantly deteriorated 1 month after (chemo)radiotherapy, but there was a tendency to return to pretreatment levels 1 year after treatment. Neither pharyngeal delay time nor displacement of the hyoid bone changed significantly before and after (chemo)radiotherapy. In addition, there was no significant difference in the mean velocity of hyoid bone movement and the amount of stasis in the pharynx at the first swallow before and after (chemo)radiotherapy. After (chemo)radiotherapy, laryngeal sensation deteriorated. But, in this study, videofluoroscopy showed that swallowing reflex and function were maintained.

    Full Text Available Breast cancer is the leading cause of cancer in females between the ages of 15 and 54, and the second leading cause of cancer death in women in the United States. Diagnosis begins with detection by breast examination (clinical breast exam or breast self-exam or by radiologic studies, like mammography. Many advances in the diagnosis of breast cancer have taken place in recent years. This article will review the history of radiologic advances in the diagnosis of breast cancer. Use of technological advancements in digital breast tomosynthesis, magnetic resonance imaging, and ultrasound in breast cancer diagnosis will be presented. Advantages and disadvantages of these diagnostic interventions when compared to older, traditional X-ray films will be discussed. It is important for all nurses, including radiology and oncology nurses, to be well informed about these varied diagnostic modalities, and appreciate the fact that advances in radiologic imaging technologies can yield improved outcomes for breast cancer patients.

    To investigate the role and significance of CD45RO in occurance and development in laryngeal squamous carcinoma, and to provide some valuable clues for searching new approaches to assess prognosis and theoretical basis for tumor biotherapy. The expression of CD45RO protein in 50 cases of laryngeal squamous carcinoma and 10 cases normal mucos was detected by immunohistochemical S-P method. The positive rate of CD45RO was 30% and 86% respectively in normal tissue and laryngeal squamous cell carcinoma tissue. The expresion of CD45RO was significantly and negatively associated with local metastatic of lymph nodes 0.713, P < 0.05) and tumor sites (r = -0.750, P < 0.05), but it have no notable difference with pathology differentiation, age, infiltrating depth and clinical stages in 50 cases of laryngeal squamous cell cancer. (1) The expresion of CD45RO in laryngeal squamous cell cancer is more than that in normal tissue. (2) It is possible that overexpresion of CD45RO in laryngeal squamous cell carcinoma cut local metastatic lymph nodes. (3) It is probable that overexpresion of CD45RO in laryngeal squamous cell cancer made for prognosis of patients. (4) Other than UICC-TNM stage, pathology differentiation, it provide valuable clues for searching new approaches to assess prognosis of laryngeal squamous cell carcinoma.

    Despite all the knowledge already gathered, the picture of somatic genetic changes in colorectal tumorigenesis is far from complete. Recently, germline and somatic mutations in the exonuclease domain of polymerase epsilon, catalytic subunit (POLE) gene have been reported in a small subset of microsatellite-stable and hypermutated colorectal carcinomas (CRCs), affecting the proofreading activity of the enzyme and leading to misincorporation of bases during DNA replication. To evaluate the role of POLE mutations in colorectal carcinogenesis, namely in advanced CRC, we searched for somatic mutations by Sanger sequencing in tumor DNA samples from 307 cases. Microsatellite instability and mutation analyses of a panel of oncogenes were performed in the tumors harboring POLE mutations. Three heterozygous mutations were found in two tumors, the c.857C>G, p.Pro286Arg, the c.901G>A, p.Asp301Asn, and the c.1376C>T, p.Ser459Phe. Of the POLE-mutated CRCs, one tumor was microsatellite-stable and the other had low microsatellite instability, whereas KRAS and PIK3CA mutations were found in one tumor each. We conclude that POLE somatic mutations exist but are rare in advanced CRC, with further larger studies being necessary to evaluate its biological and clinical implications. © 2017 The Authors.

    2016-11-01

    Full Text Available Immunotherapy is heralded as one of the most important advances in oncology. Until recently, only limited immunotherapeutic options were available in selected immunogenic cancers like melanoma and renal cell carcinomas. Nowadays, there is an improved understanding that anti-tumor immunity is controlled by a delicate balance in the tumor microenvironment between immune stimulatory and immune inhibitory pathways. Either by blocking the inhibitory pathways or stimulating the activating pathways that regulate cytotoxic lymphocytes, anti-tumor immunity can be enhanced leading to durable anti-tumor responses. Drugs which block the immune regulatory checkpoints namely the PD-1/PDL1 and CTLA 4 pathway have shown tremendous promise in a wide spectrum of solid and hematological malignancies, significantly improving overall survival in newly diagnosed and heavily pretreated patients alike. Hence there is renewed enthusiasm in the field of immune oncology with current research focused on augmenting responses to checkpoint inhibitors by combination therapy as well as studies looking at other immune modulators and adoptive T cell therapy. In this article, we highlight the key clinical advances and concepts in immunotherapy with particular emphasis on checkpoint inhibition as well as the future direction in this field.

    Nine patients with advanced head and neck cancer were treated by irradiation consisting of three fractions a day of 180 rad administered with intervals of 4 h. The total dose was 4860-5400 rad in an overall time of 11-12 days. The acute mucosal reactions produced by this multifractionated schedule were similar to those observed with conventional fractionation. The acute skin reactions were minimal. The period of acute reactions were shorter than is generally observed with conventional fractionation. In six patients with a follow-up time of six months or longer no late reactions were detected with the exception of one patient requiring permanent tracheostomy because of laryngeal oedema. In the whole group of patients loco-regional control of the disease was achieved. Six patients had maintained the full response for six months or longer. The results so far obtained with this multiple fractions a day schedule are encouraging. More patients have to be entered in this study in order to draw definitive conclusions. (author)

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

    Full Text Available Skin metastases from advanced colorectal cancer are relatively rare and occur most often when the cancer is advanced, following the spread to other organs. Cutaneous metastases occur in about 3% of advanced colorectal cancers. We present an extremely rare case of a 68-year-old woman with advanced ascending colon adenocarcinoma that presented with multiple rapidly progressing painless cutaneous metastatic lesions with no other distant metastases. Of all the tumors, breast cancer most commonly spreads as cutaneous metastasis is followed by lung, colorectal, renal, ovarian, and bladder cancers. Cutaneous metastases can present in a variety of clinical manifestations, such as a rapidly growing painless dermal or subcutaneous nodule with intact overlying epidermis or as ulcers. In cases where the cutaneous deposit is isolated, as in visceral metastasis, there is a role for radical management such as wide local excision and reconstruction. In our patient, since she had multiple cutaneous metastases she began treatment with palliative systemic combination chemotherapy.

    Although medical treatment has been shown to improve quality of life and prolong survival, no significant progress has been made in the treatment of advanced gastric cancer (AGC) within the last two decades. Thus, the optimum standard first-line chemotherapy regimen for AGC remains debatable, and most responses to chemotherapy are partial and of short duration; the median survival is approximately 7 to 11 months, and survival at 2 years is exceptionally > 10%. Recently, remarkable progress in tumor biology has led to the development of new agents that target critical aspects of oncogenic pathways. For AGC, many molecular targeting agents have been evaluated in international randomized studies, and trastuzumab, an anti-HER-2 monoclonal antibody, has shown antitumor activity against HER-2-positive AGC. However, this benefit is limited to only ~20% of patients with AGC (patients with HER-2-positive AGC). Therefore, there remains a critical need for both the development of more effective agents and the identification of molecular predictive and prognostic markers to select those patients who will benefit most from specific chemotherapeutic regimens and targeted therapies.

To challenge positivist–empiricist assumptions, I am seeking to develop a new theoretical framework that is grounded in the advanced cancer patient’s experience of activity. Aim: To gain an in-depth understanding of the experience of activity and quality of life in advanced cancer patients. Objectives: (1 To explore the meaning of activity for advanced cancer patients in the context of their day-to-day life, (2 to elicit advanced cancer patients’ perceptions of activity with respect to their quality of life, and (3 to elicit advanced cancer patients’ views of barriers and facilitators to activity in the context of their day-to-day life. Study Design: A two-phase, cross-sectional, qualitative study will be conducted through the postpositivist lens of subtle realism and informed by the principles of grounded theory methods. Study Methods: Advanced cancer patients will be recruited through the outpatient department of a tertiary cancer center. For Phase one, participants will wear an activPAL™ activity monitor and fill out a daily record sheet for seven days duration. For Phase two, the activity monitor output and daily record sheets will be used as qualitative probes for face-to-face, semistructured interviews. Concurrent coding, constant comparative analysis, and theoretical sampling will continue with the aim of achieving as close as possible to theoretical saturation. Ethics and Discussion: Ethical and scientific approval will be obtained by all local institutional review boards prior to study commencement. The findings will generate new mid-level theory about the experience of activity and quality of life in advanced cancer patients and aid in the development of a new theoretical framework for designing

    Full Text Available Laryngeal carcinoma is rarely associated with paraneoplastic syndrome. Inflammatory myopathy presenting as paraneoplastic event is commonly associated with carcinomas of ovary, lung, pancreas, stomach, colorectal, and non-Hodgkin′s lymphoma. We report a case of elderly male, who presented with proximal muscle weakness and found to be associated with laryngeal carcinoma. Diagnosis of polymyositis (PM was confirmed based on clinical features, laboratory test, and muscle biopsy. Exclusion of other commonly associated malignancies was done. This patient improved gradually after 6 months of immunosuppressive therapy and management of underlying cancer.

    To compare cardiac autonomic modulation in early- versus advanced-stage breast cancer patients before any type of cancer treatment and investigate associated factors. This cross-sectional study included women (30-69 years old) with primary diagnosis of breast cancer and women with benign breast tumors. We evaluated cardiac modulation by heart rate variability and assessed factors of anxiety, depression, physical activity, and other relevant medical variables. Patients were divided into three groups based on TNM staging of cancer severity: early-stage cancer (n = 42), advanced-stage cancer (n = 37), or benign breast tumors to serve as a control (n = 37). We analyzed heart rate variability in time and frequency domains. The advanced-stage cancer group had lower vagal modulation than early-stage and benign groups; also, the advance-stage group had lower overall heart rate variability when compared to benign conditions. Heart rate variability was influenced by age, menopausal status, and BMI. Heart rate variability seems to be a promising, non-invasive tool for early diagnosis of autonomic dysfunction in breast cancer and detection of cardiovascular impairments at cancer diagnosis. Cardiac autonomic modulation is inversely associated with breast cancer staging.

    Since the development of conservation laryngeal surgery and the advent of computed tomography (CT) scanners, a precise preoperative evaluation of the extent of laryngeal cancer has been of prime importance. Eight patients with known carcinoma of the larynx were examined with CT of the larynx prior to surgery, and whole-mount serial sections of the extirpated larynx were compared with the corresponding level of CT sections to evaluate the reliability of CT during my study abroad in Japan from Dec. 1985 through Dec. 1986. 1. The results indicated that CT scanning accurately delineates the anatomic location and pathologic extent of the tumor three-dimensionally in all cases examined. There is also good demonstration of the anterior commissure and preepiglottic, paraglottic and subglottic spaces which are sometimes poorly seen by laryngoscopy or by any other means. 2. Determination of invasion of the laryngeal cartilage by tumor proved to be very difficult to diagnose with CT. 3. The CT images obtained while the patient is breathing quietly, coupled with additional sections at the level of the vocal cord during slight valsalva maneuver afford good visualization of laryngeal tumors. 4. It should be emphasized that a thorough pathologic examination of extirpated specimens with serial sections is essential for laryngeal surgeons, because it is impossible to determine the patient's prognosis without microscopic demonstration of the degree of invasion.

  17. Advanced Breast Cancer as Indicator of Quality Mammography

    Gaona, Enrique

    2003-01-01

    Breast cancer is the most frequently diagnosed cancer and is the second leading cause of cancer death among women in the Mexican Republic. Mammography is the more important screening tool for detecting early breast cancer. Screening mammography involves taking x-rays from two views from each breast, typically from above (cranial-caudal view, CC) and from an oblique or angled view (mediolateral-oblique, MLO). The purpose of this study was to carry out an exploratory survey of the issue of patients with advanced breast cancer who have had a screening mammography. A general result of the survey is that 22.5% of all patients (102) with advanced breast cancer that participated in the study had previous screening mammography. But we should consider that 10% of breast cancers are not detected by mammography. Only 70% of the family doctors prescribed a diagnostic mammography when the first symptoms were diagnosed

  18. Section four: laryngitis and dysphonia.

    2013-12-01

    Acute laryngitis is most often caused by viral illnesses through direct inflammation of the vocal cords or from irritation due to postnasal drainage. Bacterial infections, such as acute epiglottitis, also can cause dysphonia but typically have other systemic symptoms as well as respiratory distress. Chronic laryngitis is characterized by symptoms lasting more than 3 weeks. Chronic vocal cord issues can be related to overuse or stress on the vocal cords resulting in nodules or polyps. Individuals in certain occupations, such as singers, school teachers, and chemical workers, are at greater risk of chronic laryngitis. The diagnostic approach to chronic laryngitis should include visualization of the vocal cords to rule out potential malignant lesions. For acute and chronic overuse symptoms, the best treatment is vocal rest. The use of antibiotics or decongestants should be discouraged.

    1984-01-01

    Computed tomography of the larynx represents a major advance in laryngology. Even in severe injury the larynx can be examined easily and conveniently by CT at the same time as the brain and facial structures without moving the patient, who need only lie down and breathe quietly during the study. Computed tomography permitted a much more detailed appraisal of laryngeal dysfunction in patients with blunt laryngeal trauma (3 cases) and strangulation injury (2 cases). Computed tomography of the larynx undoubtedly played a determinant role in patient management. Computed tomography was helpful in evaluating the laryngeal cartilages and deep spaces of the larynx which was difficult to examine by the laryngoscope. Follow-up computed tomography made it possible to evaluate the postoperative results

    2010-01-01

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

    2018-01-01

    Transoral laser microsurgery applies to the piecemeal removal of malignant tumours of the upper aerodigestive tract using the CO 2 laser under the operating microscope. This method of surgery is being increasingly popularised as a single modality treatment of choice in early laryngeal cancers (T1 and T2) and occasionally in the more advanced forms of the disease (T3 and T4), predominantly within the supraglottis. Thomas Kuhn, the American physicist turned philosopher and historian of science, coined the phrase 'paradigm shift' in his groundbreaking book The Structure of Scientific Revolutions. He argued that the arrival of the new and often incompatible idea forms the core of a new paradigm, the birth of an entirely new way of thinking. This article discusses whether Steiner and colleagues truly brought about a paradigm shift in oncological surgery. By rejecting the principle of en block resection and by replacing it with the belief that not only is it oncologically safe to cut through the substance of the tumour but in doing so one can actually achieve better results, Steiner was able to truly revolutionise the management of laryngeal cancer. Even though within this article the repercussions of his insight are limited to the upper aerodigestive tract oncological surgery, his willingness to question other peoples' dogma makes his contribution truly a genuine paradigm shift.

    Many studies have reported increased expression of S100 A7 (psoriasin) in neoplastic lesions. Among them are studies on breast carcinoma, bladder squamous cell carcinoma, skin tumors and oral cavity squamous cell carcinoma. The expression of S100 A7 has not been described for laryngeal cancer. This study aims to identify the expression of the calcium-binding protein S100 A7 and its correlation with squamous cell carcinomas of the larynx. Specimens from 63 patients were submitted to immunohistochemistry testing with antibody S100 A7. Results were classified and compared. The group with highly differentiated tumors had the highest treatment failure scores. Moderately differentiated tumors had higher treatment failure scores than poorly differentiated tumors. Higher scores were predominantly seen on stages I and II in moderately differentiated tumors, whereas score distribution was more homogeneous in advanced stage disease (III and IV). Regarding failure in treatment, the group scoring zero (3/4 complications: 75%) differed significantly from the remaining groups (13/59: 22%). S100 A7 marker was expressed in 93.7% of laryngeal cancer cases, with higher positive correlation rates in more differentiated tumors and significantly lower rates of treatment failure. Scores had no impact on survival rates.

    Colorectal cancer is the second most frequent malignant tumor in the United States and fourth most frequent tumor in Korea. Surgery has been used as a primary treatment modality but reported overall survivals after curative resection were from 20% to 50%. Local recurrence is the most common failure in the treatment of locally advanced colorectal cancer. Once recurrence has developed, surgery has rarely the role and the five year survival of locally advanced rectal cancer is less than 5%, this indicated that significant improvement of local control could be achieved. We performed 6 cases of IORT for locally advanced colorectal cancer which is he first experience in Korea. Patient's eligibility, treatment applicator, electron energy, dose distribution on the surface and depth within the treatment field and detailed skills are discussed. We hope that our IORT protocol can reduce local failure and increase the long term survival significantly

    2015-01-01

    Cancer is a leading cause of death worldwide; due to the lack of ideal cancer biomarkers for early detection or diagnosis, most patients present with late-stage disease at the time of diagnosis, thus limiting the potential for successful treatment. Traditional cancer treatments, including surgery, chemotherapy and radiation therapy, have demonstrated very limited efficacy for patients with late-stage disease. Therefore, innovative and effective cancer treatments are urgently needed for cancer patients with late-stage and refractory disease. Cancer immunotherapy, particularly adoptive cell transfer, has shown great promise in the treatment of patients with late-stage disease, including those who are refractory to standard therapies. In this review, we will highlight recent advances and discuss future directions in adoptive cell transfer based cancer immunotherapy. PMID:25524383

    Prostate cancer is the second most common cancer in the world, and the incidence of prostate cancer in China shows an upward trend. MRI has high soft tissue resolution and multi-dimensional imaging advantages, and it can better show the anatomy of the prostate and adjacent tissue structures. With the development of MR technique, it plays a more and more important role in prostate cancer diagnosis. This review starts from the imaging performance of routine MRI sequence of prostate cancer, and a variety of functional MRI applications in the diagnosis and differential diagnosis of prostate cancer are described in detail, such as MR perfusion-weighted imaging, MR spectroscopy, MR diffusion-weighted imaging, MR diffusion tensor imaging, intravoxel incoherent motion diffusion-weighted imaging, MR susceptibility-weighted imaging. Meanwhile this review introduces that functional MRI has more advantages and can provide more image information than routine MRI sequence. According to a series of semi-quantitative and quantitative data, functional MRI can further provide the blood perfusion of prostate cancer, water molecule diffusion and microcirculation state, metabolism and biochemical composition change information.

    Progressive, incurable cancer is associated with increased fatigue, increased muscle weakness, and reduced physical functioning, all of which negatively impact quality of life. Physical activity has demonstrated benefits on cancer-related fatigue and physical functioning in early-stage cancer patients; however, its impact on these outcomes in end-stage cancer has not been established. The aim of this systematic review is to determine the potential benefits, harms, and effects of physical activity interventions on quality of life outcomes in advanced cancer patients. A systematic review of peer-reviewed literature on physical activity in advanced cancer patients will be undertaken. Empirical quantitative studies will be considered for inclusion if they present interventional or observational data on physical activity in advanced cancer patients. Searches will be conducted in the following electronic databases: CINAHL; CIRRIE Database of International Rehabilitation Research; Cochrane Database of Systematic Reviews (CDSR); Database of Abstracts of Reviews of Effects (DARE); Cochrane Central Register of Controlled Trials (CENTRAL); EMBASE; MEDLINE; PEDro: the Physiotherapy Evidence Database; PQDT; PsycInfo; PubMed; REHABDATA; Scopus; SPORTDiscus; and Web of Science, to identify relevant studies of interest. Additional strategies to identify relevant studies will include citation searches and evaluation of reference lists of included articles. Titles, abstracts, and keywords of identified studies from the search strategies will be screened for inclusion criteria. Two independent reviewers will conduct quality appraisal using the Effective Public Health Practice Project Quality Assessment Tool for Quantitative Studies (EPHPP) and the Cochrane risk of bias tool. A descriptive summary of included studies will describe the study designs, participant and activity characteristics, and objective and patient-reported outcomes. This systematic review will summarize the current

    This systematic review synthesizes the complex literature on prognostic awareness in cancer. A total of 37 studies examining cancer patients' understanding of their prognosis were included. Prognostic awareness definitions and assessment methods were inconsistent across studies. A surprisingly high percentage of patients (up to 75%) were unaware of their poor prognosis, and in several studies, even their cancer diagnosis (up to 96%), particularly in studies conducted outside of North America. This review highlights surprisingly low rates of prognostic awareness in patients with advanced cancer as well as discrepancies in prognostic awareness assessment, suggesting the need for empirically validated measures of prognostic awareness. © The Author(s) 2013.

    2013-08-01

    We aimed to investigate the factors contributing to poor recruitment to the EaStER trial "Early Stage glottic cancer: Endoscopic excision or Radiotherapy" feasibility study. We performed a prospective qualitative assessment of the EaStER trial at three centres to investigate barriers to recruitment and implement changes. Methods used included semi-structured interviews, focus groups and audio-recordings of recruitment encounters. First, surgeons and recruiters did not all accept the primary outcome as the rationale for the trial. Surgeons did not always adhere to the trial eligibility criteria leading to variations between centres in the numbers of "eligible" patients. Second, as both treatments were considered equally successful, recruiters and patients focused on the pragmatics of the different trial arms, favouring surgery over radiotherapy. The lack of equipoise was reflected in the way recruiters presented trial information. Third, patient views, beliefs and preferences were not fully elicited or addressed by recruiters. Fourth, in some centres, logistical issues made trial participation difficult. This qualitative research identified several major issues that explained recruitment difficulties. While there was insufficient time to address these in the EaStER trial, several factors would need to be addressed to launch further RCTs in head and neck cancer. These include the need for clear ongoing agreement among recruiting clinicians regarding details in the study protocol; an understanding of the logistical issues hindering recruitment at individual centres; and training recruiters to enable them to explain the need for randomisation and the rationale for the RCT to patients.

    Neoadjuvant radiotherapy for breast cancer has rarely been reported. In the present study, we investigated the objective response and histopathological effects of neoadjuvant radiotherapy in patients with primary advanced or locally recurrent breast cancer. Between 1992 and 1997, a total of 11 patients with primary or recurrent breast cancer (5 primary advanced and 6 locally recurrent breast cancers) were treated with neoadjuvant radiotherapy before surgery. Six patients received radiotherapy alone and 5 received radiotherapy in combination with chemotherapy, and the objective response was assessed according to the criteria of the Japanese Society of Cancer Therapy. After neoadjuvant radiotherapy or radiochemotherapy, all patients underwent surgery or biopsy, and histopathological effects were assessed according to the criteria of the Japanese Research Society for Gastric Cancer Study. The overall objective response was 27% (3PR/11; 2PR in 5 primary cancers and 1PR in 6 recurrent cancers), and histopathological effects included 5 grade-3 or -2 responses (45%; 2 grade-3 and 1 grade-2 in primary cancers and 2 grade-2 in recurrent cancers). There were no correlations between total radiation dose and objective response or histopathological effects. The objective response rates were 40% (2/5) in the radiochemotherapy group and 17% (1/6) in the radiotherapy alone group, histopathological effects higher than grade-2 were seen in 60% (3/5) in the radiochemotherapy group and 33% (2/6) in the radiotherapy alone group, and a grade-3 response was seen only in the radiochemotherapy group. Neoadjuvant radiotherapy for breast cancer resulted in a high response rate and was more effective against primary cancer than recurrent cancer. Furthermore, chemotherapy may be beneficial in improving the efficacy of radiotherapy. (author)

Prognosis remains poor with most patients presenting with advanced or metastatic disease. A better understanding of angiogenesis has led to the investigation of drugs that inhibit the vascular endothelial growth factor (VEGF pathway including anti-VEGF antibody therapy (eg, bevacizumab, inhibitors of angiogenic receptor tyrosine kinases (eg, sunitinib, sorafenib, apatinib, regorafenib, and inhibitors of vascular endothelial growth factor receptors (VEGFRs (eg, ramucirumab. Ramucirumab, a VEGFR-2 inhibitor, is the first anti-angiogenic agent approved by the US Food and Drug Administration for use in the treatment of advanced gastric cancers. This review will focus on the clinical utility and potential use of ramucirumab in advanced gastric cancer.

    Radiation therapy combined with radiofrequency (RF) hyperthermia was performed on 5 advanced cancer patients. Included were one each with urinary bladder cancer, hepatoma with left axillary node metastasis, breast cancer, tongue cancer with left cervical metastasis, and mandibular cancer. All had large tumors, which were judged to be uncontrollable by radiotherapy alone. They were treated with irradiation (Linac: 10 MV X-ray 1.8 - 2.0 Gy/day, 5 days/week), followed within an hour by RF hyperthermia once or twice a week. Partial response was obtained in the urinary bladder cancer patient. Surface overheating around the margin of electrodes occurred in all but no severe complications were observed. (author)

    Full Text Available PURPOSE: To demonstrate the economical impact of surgical castration in comparison to the medical castration for patients with advanced prostate cancer. MATERIAL AND METHODS: Between January 2001 and December 2001, 32 patients with advanced prostate cancer underwent bilateral sub-capsular orchiectomy at our Hospital. The costs of this procedure were compared to the costs of medical castration with LH-RH analogues. RESULTS: The costs of the surgical procedure were extremely reduced when compared to published data on the medical treatment. Surgical castration did not have any stronger negative impact on the evolution of these patients when compared to medical castration. CONCLUSION: Surgical castration is an efficient and low cost treatment for advanced prostate cancer.

    Chemoradiotherapy is frequently applied as the first-line therapy for advanced hypopharyngeal cancer. However, organ-preserving therapy does not allow true pathological assessment of the effectiveness of the therapy. We therefore determined the following treatment modality for advanced hypopharyngeal cancer based on local findings upon the completion of radiotherapy at 40 Gy. Pathological assessments of 33 cases of advanced hypopharyngeal cancer who had undergone extended operation after chemoradiotherapy were performed. The pathological effects were 12 cases of Grade 1, 13 cases of Grade 2 and 8 cases of Grade 3. However, the rate of tumor-free cases was only 60% of the extended operation. In those cases, the local controlled lesions were well, however, distant metastases influenced the outcome; to control distant metastasis is a future issue. Additional studies to select a surgical approach will be needed. (author)

    Functional preservation is important in the treatment of advanced oral cancer in terms of patient's quality of life (QOL), therefore surgery is not ideal for advanced oral cancer. In order to ensure both curability and functional preservation, superselective intra-arterial chemoradiotherapy (SSIACRT), which is considered to be superior to conventional surgical treatment, has been conducted. Thirty-four patients with advanced oral cancer have been treated with SSIACRT with a combination of nedaplatin (CDGP) and docetaxel (DOC) since 2003. Complete response was achieved in 30 (89%) out of the 34 patients. Amongst the 25 patients with positive neck diseases, 23 (92%) were assessed as disease-free. The 5-year overall survival rate was 71.4%. Wide resection of both primary and neck lesions was avoidable and oral cavity function (swallowing, speech, mastication) after SSIACRT was satisfactory. A problem for SSIACRT is the development of late adverse events of xerostomia and osteoradionecrosis. (author)

    Nearly half of breast cancer patients in developing countries present with a locally advanced cancer. Treatment is centered on a multimodal approach based on chemotherapy, surgery and radiotherapy. The growing use of neoadjuvant chemotherapy has led to a more conservative surgical approach; nonetheless, it is not yet considered as a standard. There are no clear recommendations on the use of a radiotherapy boost in such situation. A Medline search was developed. Most articles are retrospective series. Survival free of locoregional relapse in patients treated with neoadjuvant chemotherapy, breast conserving surgery and radiotherapy is good. All articles described a boost administered to nearly all patients without regard to their prognostic factors, given that a locally advanced tumor is already considered as a poor prognostic factor. Even tough the poor level of evidence, a recommendation can be made: radiotherapy boost should be administered to all patients with locally advanced breast cancer treated with neoadjuvant chemotherapy and breast conserving surgery.

    Objective: To evaluate the clinical efficacy of intraarterial infusion chemotherapy in patients with advanced and/or recurrent breast cancer. Methods: From February 2000 to March 2003, 18 patients with advanced and/or recurrent breast cancer were treated with interaarterial chemotherapy (IAC). The Seldinger's technique was used in all patients. IAC was administered for 2-3 courses every 3-4 weeks for each patient. Results: The procedure was successfully performed in all 18 patients including one with a complete response, 12 of a partial response, none in 3, and with progression in 2. The overall response rate was 72.2%. The frequent adverse effects were fever, leukopenia, nausea, and vomiting but no severe complication occurred. Conclusion: Intraarterial infusion chemotherapy is a safe, simple, complication-free and effective in the patients with advanced and/or recurrent breast cancer. (authors)

    Renal transplantation is a standard procedure for end-stage renal disease today. Due to immunosuppressive drugs and increasing survival time after renal trans-plantation, patients with transplanted kidneys carry an increased risk of developing malignant tumors. In this case report, 3 patients with advanced rectal can-cer after renal transplantation for renal failure were treated with anterior resection or abdominoperineal resection plus total mesorectal excision, followed by adjuvant chemotherapy. One patient eventually died of metastasized cancer 31 mo after therapy, although his organ grafts functioned well until his death. The other 2 patients were well during the 8 and 21 mo follow-up periods after rectal resection. We therefore strongly argue that patients with advanced rectal cancer should receive standard oncology treatment, including opera-tion and adjuvant treatment after renal transplantation. Colorectal cancer screening in such patients appears justified.

    Aberrant expression of HGF/SF and its receptor, c-Met, often correlates with advanced prostate cancer. Our previous study showed that expression of c-Met in prostate cancer cells was increased after attenuation of androgen receptor (AR) signalling. This suggested that current androgen ablation therapy for prostate cancer activates c-Met expression and may contribute to development of more aggressive, castration resistant prostate cancer (CRPC). Therefore, we directly assessed the efficacy of c-Met inhibition during androgen ablation on the growth and progression of prostate cancer. We tested two c-Met small molecule inhibitors, PHA-665752 and PF-2341066, for anti-proliferative activity by MTS assay and cell proliferation assay on human prostate cancer cell lines with different levels of androgen sensitivity. We also used renal subcapsular and castrated orthotopic xenograft mouse models to assess the effect of the inhibitors on prostate tumor formation and progression. We demonstrated a dose-dependent inhibitory effect of PHA-665752 and PF-2341066 on the proliferation of human prostate cancer cells and the phosphorylation of c-Met. The effect on cell proliferation was stronger in androgen insensitive cells. The c-Met inhibitor, PF-2341066, significantly reduced growth of prostate tumor cells in the renal subcapsular mouse model and the castrated orthotopic mouse model. The effect on cell proliferation was greater following castration. The c-Met inhibitors demonstrated anti-proliferative efficacy when combined with androgen ablation therapy for advanced prostate cancer

    We studied the effects of a splenectomy in combination with immunotherapy on the survival of patients who had undergone a total gastrectomy. It was found that a splenectomy was not effective against advanced gastric cancer at stage III, and that the spleen should be retained for immunotherapy. Splenectomy for gastric cancer at terminal stage IV, particularly in combination with immunotherapy, produced not only augmentation of cellular immunity, but also increased survival.

    Cancer cells are highly dependent on metabolic pathways to sustain both their proliferation and adaption to harsh microenvironments. Thus, understanding the metabolic reprogramming that occurs in tumors can provide critical insights for the development of therapies targeting metabolism. In this review, we will discuss recent advancements in metabolomics and other multidisciplinary techniques that have led to the discovery of novel metabolic pathways and mechanisms in diverse cancer types.

    The cervical cancer is the third most common malignancy in women in the world. Despite advances in screening and treatment there are a relatively large number of patients who are diagnosed with advanced stage of disease, or who have inoperable recurrence. In this group of patients, the main aim of a treatment is palliative intent. The main cytotoxic agent is cisplatin, but the responses are also observed with other chemotherapy agents. Improved therapeutic results are observed with combined platinum-based chemotherapy regimens as compared to cisplatin monotherapy. Overall, however, the treatment results in advanced, persistent and recurrent cervical cancer are unfavorable and disease is considered to be relatively chemo resistant. The new treatment approaches are searched and a significant therapeutic benefit, as far as progression-free and overall survival, has been recently demonstrated when adding bevacizumab to systemic chemotherapy. The current article is a review of systemic treatment in advanced, persistent and recurrent metastatic carcinoma of the cervix. (author)

    Intraoperative radiotherapy (IORT) was performed on 20 patients with colorectal cancer. IORT with a single dose of 20 to 40 Gy was delivered to the residual tumor, tumor bed, and/or lymphnode regions. Although most of the patients had advanced lesions, local control was achieved in 67 % of the patients when IORT was combined with tumor resection, and 4 patients survived more than 5 years. There were no serious complications, except for contracture or atrophy of the psoas muscle seen in 2 patients. IORT combined with external beam radiotherapy should be a useful adjuvant therapy to surgery for locally advanced colorectal cancer. (author)

    During thyroidectomy and neck dissection surgery for advanced or recurrent metastatic thyroid cancer under intraoperative monitoring, we used the available technology to assess the feasibility of such an intervention to monitor those patients with phrenic nerves at risk. A retrospective review of patients operated on from January 2009 to December 2015 by a single surgeon (CSD) was conducted. Patients who had neck and mediastinal dissection, with or without total thyroidectomy, due to advanced or recurrent metastatic disease to the neck were selected. The procedures were done under intraoperative nerve monitoring using nerve monitoring systems (NIM 2.0 or 3.0; Medtronic, Jacksonville, FL, USA). A total of 19 patients were included in the study, with a mean age of 57.6 years ± 16.3 and a male/female ratio of 10:9. Overall, all patients had an intact phrenic nerve at the conclusion of the surgery. One patient had an aggressive tumor that precluded sacrifice of the left recurrent laryngeal nerve and ipsilateral thoracic duct. The procedure was complicated by a temporary impairment of the diaphragm contraction with intraoperative nerve monitoring as well as a chyle fistula. This was due to the manipulation of the tissue surrounding the phrenic nerve. Intraoperative nerve monitoring of the phrenic nerve offers the surgeon a "potential" method of ensuring phrenic nerve integrity in cases of advanced thyroid cancers with gross level IV metastatic disease. Further prospective studies are needed to assess the risks of this intervention and evaluate the method of recording diaphragm contraction movement.

    Clinical results of intraoperative radiotherapy (IOR) in carcinoma of the stomach and prostate, and malignant soft tissue tumors are reported. The 5-year survival rate was found to be increased by IOR in stages II-IV gastric cancer. From the analysis of the clinical results of prostatic cancer, a single dose of 3,500 rad was considered to be a potential curative dose for the tumor less than 3 cm in diameter. The local recurrence rate of patients with malignant soft tissue tumors who received a single dose ranging from 3,000 to 4,500 rad was 5.9 and the 5-year survival rate was 64.6 %.

    Mumps virus infection primarily affects the salivary glands and may incur various complications. Laryngeal edema is such a rare complication that few adult cases have been reported. We report the first known pediatric patient with mumps with laryngeal edema. An 8-year-old boy developed dyspnea after a rapidly progressive swelling of his face and neck. Laryngoscopy revealed edematous changes in the supraglottic and subglottic regions, and computed tomography confirmed significant laryngeal edema in addition to swelling of the cervical soft tissue and the salivary glands. Laboratory findings revealed a high serum amylase level and confirmed the diagnosis of mumps. Intravenous steroid administration alleviated the dyspnea, although the patient required temporary tracheal intubation to maintain airway patency. He did not need tracheotomy and did not experience any other complications. Laryngeal edema must be regarded as a rare, potentially life-threatening complication of mumps. When mumps is diagnosed with significant swelling of the neck, an emergency airway should be established to prevent airway obstruction.

    To investigate factors influencing response and survival for patients with squamous cell cancer of the esophagus. Forty-nine patients with squamous cell cancer of the esophagus, classified by guidelines for the clinical and pathologic studies on carcinoma of the esophagus published by the Japanese Society for Esophageal Disease, were treated by concurrent chemoradiotherapy using chemotherapy consisting of cisplatin and 5-fluorouracil with definitive irradiation of 60 Gy concurrently. Endoscopic findings and biopsy were used for evaluating the response. Nurse charts recording patient's feeding status were adopted to estimate severity of dysphagia. Complete response (CR) rate was 69.4%, median survival time (MST) was 12.3 months, and median local failure-free survival time 7.3 months. Patients in early stage (= 32.4 months, 20.4 months, 20.4 months, 15.7 months, respectively). Patients in A3 stage were often suffered from severe dysphagia both before and after treatment (81.5%, 70.4%), respectively. Concurrent chemoradiotherapy was effective treatment for esophageal cancer. Degree of dysphagia was considered to be a good prognosticator of patients' survival. (author)

    Conventional treatment of cervical cancer, such as radical hysterectomy with lymphadenectomy or pelvic exenteration, is limited to the pelvis. Standard radio-therapeutic treatment is a combination of external-beam radiotherapy to the pelvis and intracavitary applications. However, there is a group of patients for whom external radiotherapy alone has limitations. This group consists primarily of patients with large pelvic lymph nodes containing metastatic cancer, metastatically involved paraaortic lymph nodes outside the usual pelvic radiation field, or large central tumors with parametrial involvement. In patients with cancer of the cervix, the incidence of metastasis to paraaortic lymph nodes is high. Attempts to treat paraaortic nodes with external radiotherapy have resulted in high complication rates because the treatment field includes the highly sensitive gastrointestinal tract. External radiation therapy after retroperitoneal exploration of lymph nodes does not seem to improve survival. In an attempt to circumvent the morbidity and mortality associated with conventional external-beam irradiation, the authors initiated a pilot study of intraoperative electron-beam irradiation of the paraaortic nodes and of the large metastatic lymph nodes in the pelvis. The intraoperative boost was followed by conventional fractionated external-beam irradiation. The theoretical advantages of this procedure include a higher radiation tumor dose without a concomitant increase in treatment morbidity and mortality

    Cancer pharmacogenetics usually considers tumor-specific targets. However, hereditary genetic variants may interfere with the pharmacokinetics of antimetabolites and other anti-cancer drugs, which may lead to severe adverse events. Areas covered: Here, the impact of hereditary genes considered in drug labels such as thiopurine S-methyltransferase (TPMT), UDP-glucuronosyltransferase 1A1 (UTG1A1) and dihydropyrimidine dehydrogenase (DPYD) are discussed with respect to guidelines of the Clinical Pharmacogenetics Implementation Consortium (CPIC). Moreover, the association between genetic variants of drug transporters with the clinical outcome is comprehensively discussed. Expert opinion: Precision therapy in the field of oncology is developing tremendously. There are a number of somatic tumor genetic markers that are indicative for treatment with anti-cancer drugs. By contrast, for some hereditary variants, recommendations have been developed. Although we have vast knowledge on the association between drug transporter variants and clinical outcome, the overall data is inconsistent and the predictability of the related phenotype is low. Further developments in research may lead to the discovery of rare, but functionally relevant single nucleotide polymorphisms and a better understanding of multiple genomic, epigenomic as well as phenotypic factors, contributing to drug response in malignancies.

    Modern advances in computers have fueled advances in imaging technologies. The improvements in imaging have in turn allowed a higher level of complexity to be incorporated into radiotherapy treatment planning systems. As a result of these changes, the delivery of radiotherapy evolved from therapy designed based primarily on plain (two dimensional) X-ray images and hand calculations to three-dimensional X-ray based images incorporating increasingly complex computer algorithms. More recently, biologic variables based on differences between tumor metabolism, tumor antigens, and normal tissues have been incorporated into the treatment process. In addition, greater awareness of the challenges to the accuracy of the treatment planning process, such as problems with set-error and organ movement, have begun to be systematically addressed, ushering in an era of socalled four-dimensional radiotherapy.

  12. SWALLOWING IN PATIENTS WITH LARYNGITIS

    Directory of Open Access Journals (Sweden)

    Isabela MODA

    Full Text Available ABSTRACT BACKGROUND: Dysphagia is described as a complaint in 32% of patients with laryngitis. OBJECTIVE: The objective of this investigation was to evaluate oral and pharyngeal transit of patients with laryngitis, with the hypothesis that alteration in oral-pharyngeal bolus transit may be involved with dysphagia. METHODS: Videofluoroscopic evaluation of the swallowing of liquid, paste and solid boluses was performed in 21 patients with laryngitis, 10 of them with dysphagia, and 21 normal volunteers of the same age and sex. Two swallows of 5 mL liquid bolus, two swallows of 5 mL paste bolus and two swallows of a solid bolus were evaluated in a random sequence. The liquid bolus was 100% liquid barium sulfate and the paste bolus was prepared with 50 mL of liquid barium and 4 g of food thickener (starch and maltodextrin. The solid bolus was a soft 2.2 g cookie coated with liquid barium. Durations of oral preparation, oral transit, pharyngeal transit, pharyngeal clearance, upper esophageal sphincter opening, hyoid movement and oral-pharyngeal transit were measured. All patients performed 24-hour distal esophageal pH evaluation previous to videofluoroscopy. RESULTS: The evaluation of 24-hour distal esophageal pH showed abnormal gastroesophageal acid reflux in 10 patients. Patients showed longer oral preparation for paste bolus and a faster oral transit time for solid bolus than normal volunteers. Patients with laryngitis and dysphagia had longer preparation for paste and solid boluses, and a faster oral transit time with liquid, paste and solid boluses. CONCLUSION: A longer oral preparation for paste and solid boluses and a faster transit through the mouth are associated with dysphagia in patients with laryngitis.

    Dysphagia is described as a complaint in 32% of patients with laryngitis. The objective of this investigation was to evaluate oral and pharyngeal transit of patients with laryngitis, with the hypothesis that alteration in oral-pharyngeal bolus transit may be involved with dysphagia. Videofluoroscopic evaluation of the swallowing of liquid, paste and solid boluses was performed in 21 patients with laryngitis, 10 of them with dysphagia, and 21 normal volunteers of the same age and sex. Two swallows of 5 mL liquid bolus, two swallows of 5 mL paste bolus and two swallows of a solid bolus were evaluated in a random sequence. The liquid bolus was 100% liquid barium sulfate and the paste bolus was prepared with 50 mL of liquid barium and 4 g of food thickener (starch and maltodextrin). The solid bolus was a soft 2.2 g cookie coated with liquid barium. Durations of oral preparation, oral transit, pharyngeal transit, pharyngeal clearance, upper esophageal sphincter opening, hyoid movement and oral-pharyngeal transit were measured. All patients performed 24-hour distal esophageal pH evaluation previous to videofluoroscopy. The evaluation of 24-hour distal esophageal pH showed abnormal gastroesophageal acid reflux in 10 patients. Patients showed longer oral preparation for paste bolus and a faster oral transit time for solid bolus than normal volunteers. Patients with laryngitis and dysphagia had longer preparation for paste and solid boluses, and a faster oral transit time with liquid, paste and solid boluses. A longer oral preparation for paste and solid boluses and a faster transit through the mouth are associated with dysphagia in patients with laryngitis.

    We evaluated the efficacy of concurrent chemoradiotherapy (CRT) using cisplatin/nedaplatin and 5-fluorouracil (5-FU) for advanced esophageal cancer. Thirteen patients with locally advanced esophageal cancer (T4 cases) and 3 with recurrence of esophageal cancer were treated with radiotherapy (40-70 Gy) and 5-FU combined and cisplatin/nedaplatin concurrently. T4 patients who obtained down-staging by CRT also underwent esophagectomy. A complete response was obtained in one case, partial response in 8 cases, and no change in 7 cases. The overall response rate was 56.3%. A pathological complete response was obtained in one case in which curative resection was performed after CRT. Bone marrow suppression was observed in 68.8% and grade 3 and 4 bone marrow suppression was observed in 43.8%. Concurrent CRT using cisplatin/nedaplatin and 5-FU for advanced esophageal cancer has a high response rate and patients obtaining down-staging by CRT as a neoadjuvant therapy have a chance for long survival after curative resection in locally advanced cases.

    Incidence and mortality rates of cancer are currently on the top of disease pattern and the number is increasing and increasing worldwide. The impact of screening program for early diagnosis has been proved their important roles in the war against cancer because it helps increase the cure rates, decrease the mortality and morbidity rates, and therefore reduces the economic-social burden. Advances in diagnostic imaging techniques, especially the hybrid imaging (X-ray and Nuclear Medicine) such as PET/CT, SPECT/CT, PET/MRI, is important in accurate staging and these help choose the optimized treatment options to prolong survival while improve the quality of life. The treatment outcomes of cancer has certain remarkable advances based on variety of research to modify, promote and strengthen the traditional treatments (surgery-chemotherapy-radiation) such as laparoscopic surgery, combined chemo-regimens, intensity modulated radiation therapy, volumetric modulated arc therapy, stereotactic radiation therapy, radio surgery, PET/CT simulation, radioactive seeds implant, selective internal radiation therapy, intra-operative radiation therapy, etc. as well as the emerge of new methods such as targeted therapy, immune therapy, radio immunotherapy, proton therapy and heavy ion. Treatment of cancer is now the “individualized treatment” with the advances of biochemistry and histopathology. To achieve the most optimal outcomes, cancer should be approached by a multi professional team including biochemistry, immunology, histopathology, surgical oncology, medical oncology and radiation oncology.

    Thirteen cases of inoperable advanced breast cancer were treated with radiotherapy between 2002 to 2012 at Nara Prefectural Hospital. All cases were treated by radiotherapy and chemo-endocrine therapy. Patients received 60-81 Gy (median 60 Gy) to the primary breast tumor. Response of the breast tumors were complete response in 3 cases (23%), partial response in 8 cases (62%) and stable disease in 2 cases (15%) (response rate: 85%). All breast tumors had been controlled and skin troubles were reduced. Radiotherapy for breast cancer is useful for primary tumor control and improved quality of life (QOL). Radiotherapy should be considered to be useful modality in the treatment of advanced breast cancer. (author)

    Recently, attempts have made to use radiotherapy in combination with chemotherapy in various solid tumors including cervical cancer. Twenty-four patients with locally advanced cervical cancer were treated with concurrent Carboplatin (16-24 mg/m 2 /day) or Nedaplatin (20 mg/m 2 /week) and conventional radiotherapy. Of 13 evaluable patients, there were nine complete responders and four partial responders. There was no renal damage or grade 4 hematological toxicity. Gastrointestinal adverse reactions were mild. One patient had grade 3 dermatologic toxicity after delayed radiation therapy. This pilot study suggests that daily Carboplatin or weekly Nedaplatin administered with standard radiation therapy is safe, well-tolerated, and thus may be useful as a radiation sensitizer in the treatment of locally advanced cervical cancer.

    Locally advanced cervical cancer has a poor prognosis, poor survival rate, and high local failure rate. A number of questions regarding the optimal agents and schedule of concurrent chemoradiation remain unanswered. To improve the cure rate for advanced or recurrent cervix cancer, we studied intra-arterial infusion chemotherapy (IAIC) with or without radiotherapy. We analyzed 52 cases of advanced or recurrent cervical cancer treated by IAIC with or without radiotherapy. IAIC regimen was separated into two groups: group I consisted of 5-FU+MMC{+-}ADM (30 cases) and group II of CDDP+MMC{+-}5-FU (22 cases). The tip of the catheter was placed in the bifurcation of abdominal aorta or the bilateral internal iliac arteries (7 cases). The overall response rate (CR+PR) was 71%, 87% in patients receiving radiotherapy, 50% in those without radiotherapy, and 100% in primary cases. The five-year survival rate was 20% in primary cases, 14% in recurrent cases, 3% in group I and 38% in group II by chemotherapy regimen. Severe (more than grade III) hematological acute side effects were found in 48% of all cases, but recovered by interruption of drugs. In 7 cases in which the tip of the catheter was placed in internal iliac arteries, there were severe skin ulcers in 2 cases and severe pain of leg or gluteal region which need narcotics in 2 cases. These data suggest that IAIC mainly with cisplatin with or without radiotherapy is one of the effective treatments for advanced or recurrent cervical cancer. But we should check blood flow distribution periodically, and control the concentration of drugs. To improve the survival rate for advanced or recurrent cervical cancer, we should discuss neoadjuvant chemotherapy followed by chemoradiotherapy and maintenance systemic chemotherapy. (author)

    Hydronephrosis is frequently encountered in advanced stage cervical cancers, and may be associated with mortality. In the present study, we aimed to demonstrate the effect of hydronephrosis on survival in patients with inoperable advanced stage cervical cancer. The study data were acquired by retrospective analysis of the patient records belonging to 165 women with FIGO (International Federation of Gynecology and Obstetrics) stage-IIIB or more advanced cervical cancer, which were not surgical candidates. Parameters including patient age, pathological diagnosis, disease stage, pelvic sidewall extension, presence of hydronephrosis and administration of chemoradiation were analyzed. Further, the effects of these variables on survival were assessed. P values less than 0.05 were considered statistically significant. The distribution of the study patients according to disease stage was as follows: 131 (79.4%) had stage-IIIB, 18 (10.9%) had stage-IVB and 16 (% 9.7) patients had stage-IVA disease. Hydronephrosis was not evident in 91 (55.2%) of these patients, whereas 41 (24.8%) had unilateral and 33 (20%) patients had bilateral hydronephrosis. When compared to mean survival in patients who did not have hydronephrosis, survival was significantly shortened in patients who had bilateral and unilateral hydronephrosis (phydronephrosis (p>0.05). Although patient age, pathological type, pelvic involvement, and chemotherapy treatment rates were similar (p>0.05), radiotherapy requirement rate and disease stage were significantly different among the study groups (pHydronephrosis was found to be a significant predictor of poor survival in patients with advanced stage cervical cancer, irrespective of unilateral or bilateral involvement.While waiting for future studies with larger sample sizes, we believe that the FIGO stages in advanced cervical cancer could further be stratified into subgroups according to presence or absence of hydronephrosis.

  7. Beyond radioiodine: novel therapies in advanced thyroid cancer

    Haugen, Bryan R.

    2004-01-01

    Full text: Thyroid cancer is a relatively common endocrine malignancy. Fortunately, many patients do well with standard therapy including surgery and radioiodine. A minority of patients have poorly differentiated thyroid carcinoma that is unresponsive to radioiodine therapy. Redifferentiation agents that 'reprogram ' these tumors to concentrate radioiodine would be of great value in treating patients with advanced thyroid cancer. The retinoid isotretinoin is the most extensively studied of these agents. It appears that 20-40% of patients respond to isotretinoin treatment by concentration of radioiodine in metastatic tumors, but the clinical utility of this redifferentiation is still unclear. In vitro studies suggest that the retinoid receptors RARβ and RXRγ are required for this effect. Abnormal DNA methylation may be an early event in thyroid tumorigenesis and methylation of the sodium iodide symporter (NIS) may play a role in loss of iodine concentration in these tumors. Inhibitors of methylation (5-azacytidine, phenylacetate and sodium butyrate) have been shown to increase NIS expression and iodine uptake in cell culture models, but published trials in humans are not yet available. Histone acetylation is required for efficient transcription of genes necessary for differentiated function. Proteins that cause histone deacetylation inhibit gene transcription and differentiated function. Inhibitors of histone deacetylation (depsipeptide, trichostatin A) have been shown to increase NIS expression and iodine uptake in poorly differentiated and undifferentiated cell lines. Finally, commonly used agents such as thiazolidine diones (diabetes) and HMG-CoA reductase inhibitors (hypercholesterolemia) have shown promise in preliminary in vitro studies in advanced thyroid cancer cell lines. Our own work has focused on receptor-selective retinoids and thiazolidine diones as potential therapy in patients with advanced thyroid cancer based on nuclear hormone receptor

    Full Text Available Novel drugs, drug sequences and combinations have improved the outcome of prostate cancer in recent years. The latest approvals include abiraterone acetate, enzalutamide and apalutamide which target androgen receptor (AR signaling, radium-223 dichloride for reduction of bone metastases, sipuleucel-T immunotherapy and taxane-based chemotherapy. Adding abiraterone acetate to androgen deprivation therapy (ADT in order to achieve complete androgen blockade has proven highly beneficial for treatment of locally advanced prostate cancer and metastatic hormone-sensitive prostate cancer (mHSPC. Also, ADT together with docetaxel treatment showed significant benefit in mHSPC. Ongoing clinical trials for different subgroups of prostate cancer patients include the evaluation of the second-generation AR antagonists enzalutamide, apalutamide and darolutamide, of inhibitors of the phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K pathway, of inhibitors of DNA damage response, of targeted alpha therapy and of prostate-specific membrane antigen (PSMA targeting approaches. Advanced clinical studies with immune checkpoint inhibitors have shown limited benefits in prostate cancer and more trials are needed to demonstrate efficacy. The identification of improved, personalized treatments will be much supported by the major progress recently made in the molecular characterization of early- and late-stage prostate cancer using “omics” technologies. This has already led to novel classifications of prostate tumors based on gene expression profiles and mutation status, and should greatly help in the choice of novel targeted therapies best tailored to the needs of patients.

    Radical gastrectomy is main treatment of gastric cancer. We analyzed patients with stage III and IV stomach cancer who had radical operation and received postoperative radiation therapy combined with or without chemotherapy retrospectively. From March 1985 to June 1993, 68 patients treated with curative resection and received postoperative adjuvant radiotherapy with 36Gy or more were evaluated. Median age was 60years(range 28-66 yrs). Thirty seven patients had non signet ring adenocarcinoma, 29 signet ring cell, 2 other cell. Patients with stage IIIA, IIIB, IV disease were 19, 25 and 24 respectively. Chemotherapy was given to all patients except two. Five-year overall survival and disease-free survival rate were 36.6% and 33.6T, respectively. Recurrence was documented in 34 patients. High recurrence was seen in omentum and peritoneum with 23.5%, and remnant stomach, anastomosis site, A-loop and E-loop had also high recurrence with 13.2%. In field locoregional recurrence was 20.7% and total distant metastases were 39.7%. Total intraabdominal failure was 47.1% and extraabdominal failure was 13.2%. Treatment toxicity was considered to be acceptable. 22.1% of patients had grade 3 and only 1 patient had grade 4 leukopenia. Six patients(8.8%) had weigh loss more than 10%. Treatment toxicity was acceptable with combined treatment with chemotherapy and radiotherapy. Locoregional recurrence was relatively low compared to distant failure with addition of irradiation. Peritoneal and omental seeding was high. Five-year survival was increased with combined modality. Radiation may eradicate minimal residual disease and improve survival. Furthermore to reduce intraabdominal failure, role of intraabdominal chemotherapy in addition to combined chemotherapy plus radiation has to be explored. (author).

    Full Text Available Abstract Background Aim of this study is to thoroughly assess pretreatment organ function in advanced head and neck cancer through various clinical outcome measures and patients' views. Methods A comprehensive, multidimensional assessment was used, that included quality of life, swallowing, mouth opening, and weight changes. Fifty-five patients with stage III-IV disease were entered in this study prior to organ preserving (chemoradiation treatment. Results All patients showed pretreatment abnormalities or problems, identified by one or more of the outcome measures. Most frequent problems concerned swallowing, pain, and weight loss. Interestingly, clinical outcome measures and patients' perception did no always concur. E.g. videofluoroscopy identified aspiration and laryngeal penetration in 18% of the patients, whereas only 7 patients (13% perceived this as problematic; only 2 out of 7 patients with objective trismus actually perceived trismus. Conclusion The assessment identified several problems already pre-treatment, in this patient population. A thorough assessment of both clinical measures and patients' views appears to be necessary to gain insight in all (perceived pre-existing functional and quality of life problems.

    Purpose: To determine patterns of failure in laryngeal cancer treated with definitive IMRT by comparing two different methods for identifying the recurrence epicenter on follow-up PET/CT. Methods: We identified 20 patients treated for laryngeal squamous cell carcinoma with definitive IMRT who had loco-regional recurrence diagnosed on PET/CT. Recurrence PET/CT scans were co-registered with the original treatment planning CT using deformable image registration with the VoxAlign deformation engine in MIM Software. Recurrence volumes were delineated on co-registered follow-up scans using a semi-automatic PETedge tool and two separate methods were used to identify the recurrence point of origin: a) Finding the point within the recurrence volume for which the maximum distance to the surface of the surrounding recurrence volume is smaller than for any other point. b) Finding the point within the recurrence volume with the maximum standardized uptake value (SUVmax), without geometric restrictions.For each method the failure pattern was determined as whether the recurrence origin fell within the original high-dose target volumes GTV70, CTV70, PTV70 (receiving 70Gy), intermediate-risk PTV59 (receiving 59.4Gy) or low-risk PTV54 (receiving 54.1Gy), in the original treatment planning CT. Results: 23 primary/nodal recurrences from the 20 patients were analyzed. The three-dimensional distance between the two different origins was on average 10.5mm (std.dev. 10mm). Most recurrences originated in the high-dose target volumes for both methods with 13 (57%) and 11 (48%) in the GTV70 and 20 (87%) and 20 (87%) in the PTV70 for method a) and b), respectively. There was good agreement between the two methods in classifying the origin target volumes with 69% concordance for GTV70, 89% for CTV70 and 100% for PTV70. Conclusion: With strong agreement in patterns of failure between two separate methods for determining recurrence origin, we conclude that most recurrences occurred within the

    Hypoxia-inducible factors (HIF-1α, -2α -3α, and -β) are key factors that control hypoxia-induced carcinogenic pathways. HIF-1α is predominantly involved in the early stages of cancer, whereas HIF-2α is actively involved in the later stages; in addition, chronic (prolonged) rather than acute (short) hypoxia is a feature of metastasis and chemoresistance that occur during the later stages of cancer. Oncometabolites, onco-miRNAs, glucose deprivation, pseudohypoxia, cytokine/chemokine secretion, and some unique upstream proteins are involved in the signaling switch from HIF-1α to HIF-2α; thus, understanding this signaling switch is critical for the treatment of advanced cancer. In this review, we highlight data relating to HIF-2α rather than HIF-1α signaling in cancer pathways and discuss prospective drugs that target this important factor. Copyright © 2018 Elsevier Ltd.

    Compared to conventional treatments, gene therapy offers a variety of advantages for cancer treatment including high potency and specificity, low off-target toxicity, and delivery of multiple genes that concurrently target cancer tumorigenesis, recurrence, and drug resistance. In the past decades, gene therapy has undergone remarkable progress, and is now poised to become a first line therapy for cancer. Among various gene delivery systems, nanoparticles have attracted much attention because of their desirable characteristics including low toxicity profiles, well-controlled and high gene delivery efficiency, and multi-functionalities. This review provides an overview on gene therapeutics and gene delivery technologies, and highlight recent advances, challenges and insights into the design and the utility of nanoparticles in gene therapy for cancer treatment.

  17. Chemotherapy resistance mechanisms in advanced skin cancer

    Full Text Available Melanoma is a most dangerous and deadly type of skin cancer, and considered intrinsically resistant to both radiotherapy and chemotherapy. It has become a major public health concern as the incidence of melanoma has been rising steadily over recent decades with a 5-year survival remaining less than 5%. Detection of the disease in early stage may be curable, but late stage metastatic disease that has spread to other organs has an extremely poor prognosis with a median survival of less than 10 months. Since metastatic melanoma is unresponsive to therapy that is currently available, research is now focused on different treatment strategies such as combinations of surgery, chemotherapy and radiotherapy. The molecular basis of resistance to chemotherapy seen in melanoma is multifactorial; defective drug transport system, altered apoptotic pathway, deregulation of apoptosis and/or changes in enzymatic systems that mediate cellular metabolic machinery. Understanding of alterations in molecular processes involved in drug resistance may help in developing new therapeutic approaches to treatment of malignant melanoma.

    Cervical cancer has a major impact on the lives of Indian women with an estimated 122, 844 new cases of cervical cancer in the year 2012. About 80% of these cases present in a locally advanced stage leading to high morbidity and mortality. Because of lack of public awareness and infrastructure for screening and early detection in developing countries, this late presentation is likely to continue in the coming years. Radiation therapy has been the treatment of choice for patients with locally advanced cancer cervix. Many clinical trials and meta-analyses have shown a significant improvement in overall and progression-free survival with decreased local and distant recurrences with the use of concurrent chemotherapy with radiation. Most of these trials have been done in women from developed countries where the patient and disease profile are entirely different from ours. Recently, few trials from India have also shown promising results in locally advanced cancer cervix with concurrent chemoradiotherapy but toxicities remain a major concern. Further exploration is required for the use of concurrent chemo radiation prior to incorporating it into routine clinical practice.

    Although a randomized controlled trial for locally advanced pancreatic cancer (PC) has demonstrated a survival advantage for treatment with gemcitabine alone, chemoradiotherapy remains the treatment of choice for locally advanced disease in Japan. The aim of this study was to compare the survival benefits associated with gemcitabine and concurrent chemoradiotherapy in locally advanced unresectable PC. Seventy-seven patients with locally advanced unresectable PC were retrospectively enrolled from April 2001 to December 2006. All cases were histologically proven, and patients received gemcitabine chemotherapy (n=30) or concurrent chemoradiotherapy (based on 5-fluorouracil, n=28, or gemcitabine, n=19, as a radiosensitizer) at Aichi Cancer Center Hospital. Patients who received chemoradiotherapy had significantly better performance status than those who had chemotherapy. Tumor response was 0% for chemotherapy and 13% chemoradiotherapy, but survival benefit was similar among patients in the chemotherapy group (overall response (OS) 12 months; progression-free survival (PFS), 3 months) and those in the chemoradiotherapy group (OS, 13 months; PFS, 5 months). Two-year survival was 21% for chemotherapy patients and 19% for chemoradiotherapy patients. Severe toxicities (Grade 3-4 National Cancer Institute-Common Toxicity Criteria, version 3.0) were significantly more frequent for chemoradiotherapy than for chemotherapy. Gemcitabine chemotherapy showed similar survival benefit compared to 5-fluorouracil- and gemcitabine-based chemoradiotherapy. (author)

    Full Text Available Abstract Background The hedgehog pathway plays a critical role in the development of prostate. However, the role of the hedgehog pathway in prostate cancer is not clear. Prostate cancer is the second most prevalent cause of cancer death in American men. Therefore, identification of novel therapeutic targets for prostate cancer has significant clinical implications. Results Here we report that activation of the hedgehog pathway occurs frequently in advanced human prostate cancer. We find that high levels of hedgehog target genes, PTCH1 and hedgehog-interacting protein (HIP, are detected in over 70% of prostate tumors with Gleason scores 8–10, but in only 22% of tumors with Gleason scores 3–6. Furthermore, four available metastatic tumors all have high expression of PTCH1 and HIP. To identify the mechanism of the hedgehog signaling activation, we examine expression of Su(Fu protein, a negative regulator of the hedgehog pathway. We find that Su(Fu protein is undetectable in 11 of 27 PTCH1 positive tumors, two of them contain somatic loss-of-function mutations of Su(Fu. Furthermore, expression of sonic hedgehog protein is detected in majority of PTCH1 positive tumors (24 out of 27. High levels of hedgehog target genes are also detected in four prostate cancer cell lines (TSU, DU145, LN-Cap and PC3. We demonstrate that inhibition of hedgehog signaling by smoothened antagonist, cyclopamine, suppresses hedgehog signaling, down-regulates cell invasiveness and induces apoptosis. In addition, cancer cells expressing Gli1 under the CMV promoter are resistant to cyclopamine-mediated apoptosis. All these data suggest a significant role of the hedgehog pathway for cellular functions of prostate cancer cells. Conclusion Our data indicate that activation of the hedgehog pathway, through loss of Su(Fu or overexpression of sonic hedgehog, may involve tumor progression and metastases of prostate cancer. Thus, targeted inhibition of hedgehog signaling may have

    Full Text Available Brendan Corkery1,2, Norma O’Donovan2, John Crown1,21St. Vincent’s University Hospital, Dublin, Ireland; 2National Institute for Cellular Biotechnology, Dublin City University, Dublin, IrelandAbstract: Improved molecular understanding of breast cancer in recent years has led to the discovery of important drug targets such as HER-2 and EGFR. Lapatinib is a potent dual inhibitor of HER-2 and EGFR. Preclinical and phase I studies have shown activity with lapatinib in a number of cancers, including breast cancer, and the drug is well tolerated. The main known drug interactions are with paclitaxel and irinotecan. The most significant side-effects of lapatinib are diarrhea and adverse skin events. Rates of cardiotoxicity compare favorably with trastuzumab, a monoclonal antibody against HER-2. This paper focuses on lapatinib in advanced and metastatic breast cancer, which remains an important therapeutic challenge. Phase II and III studies show activity as monotherapy, and in combination with chemotherapy or hormonal agents. Results from these studies suggest that the main benefit from lapatinib is in the HER-2 positive breast cancer population. Combinations of lapatinib and trastuzumab are also being studied and show encouraging results, particularly in trastuzumab-refractory metastatic breast cancer. Lapatinib may have a specific role in treating HER-2 positive CNS metastases. The role of lapatinib as neoadjuvant therapy and in early breast cancer is also being evaluated.Keywords: HER-2, EGFR, erbB, lapatinib, Tykerb®, tyrosine kinase

    2004-06-01

    To report the incidence and prognostic implications of obstructive uropathy (OU) in patients with advanced prostate cancer receiving androgen deprivation therapy and to define the impact initial local therapy has on the development of OU in patients with prostate cancer who develop recurrence and begin androgen deprivation therapy. From a population of 260 patients with advanced prostate cancer diagnosed between 1986 and 2003, OU was identified in 51 patients. The OU treatment options included ureteral stent, percutaneous nephrostomy, transurethral resection of the prostate, Foley catheter placement, and urinary diversion. Overall survival and the factors that influenced survival were calculated using standard statistical methods. OU was diagnosed in 15 (16%) of 80 patients who received local therapy with curative intent and in whom local therapy subsequently failed and in 36 (19%) of 180 patients who had never received local therapy (P = 0.7, chi-square test). Of these 51 patients, 39 had bladder neck obstruction and 16 had ureteral obstruction. Overall survival was significantly worse for the men with OU compared with those without OU (41 versus 54 months). OU was associated with tumor stage and androgen-insensitive prostate cancer. OU results in significantly reduced survival in men with prostate cancer. In a select group of patients with prostate cancer with progression after local therapy (primarily radiotherapy), no statistically significant reduction in the development of OU was observed relative to patients matched for stage, grade, and pretreatment prostate-specific antigen level treated with androgen deprivation therapy alone. Aggressive advanced stage and hormone-insensitive disease are variables associated with OU.

    Increasing burden of cancer in Europe and socio-demographic trends imply that more cancer patients will face high levels of dependency. Care dependency is often perceived as a distressing experience by cancer patients who are concerned about becoming a burden to others. The experience of care dependence has been scarcely investigated in advanced cancer patients, especially in the hospital setting. This study aimed at describing advanced cancer patients' experiences of care dependence in hospital and of the factors perceived by them as contributing to decrease or increase this dependence. The study used a descriptive phenomenological approach based on Husserl's (1913) life world perspective. Data collection and analysis followed Giorgi's (1997) five basic methodological steps. Data were gathered by semi-structured interviews with thirteen advanced cancer adult inpatients of a teaching hospital. The interviews were audio-recorded and the recordings transcribed word for word. Three themes emerged: 'dependency discovers new meanings of life', 'active coping with dependency' and 'the care cures the dependent person'. The essential meaning of care dependency was the possibility to become aware of being a person as both an object and subject of care. Dependence appears as an experience with strong relational connotations, which enable patients to see differently their life, themselves, the world and others. Dependency is revealed as a natural experience, only partly in accordance with previous studies. Deeper insight into the meaning patients attach to care dependency can enable nurses to better meet the patient's needs, e.g. by improving caring relationships with patients.

    Laparoscopic distal gastrectomy has recently become accepted as a surgical option for early gastric cancer in the distal stomach, but laparoscopic total gastrectomy (LTG) has not become widespread because of technical difficulties of esophagojejunal anastomosis and splenic hilar lymphadenectomy. Splenic hilar lymphadenectomy should be employed in the treatment of advanced proximal gastric cancer to complete D2 dissection, but laparoscopically it is technically difficult even for skilled surgeons. Based on the evidence that prophylactic combined resection of spleen in total gastrectomy increased the risk of postoperative morbidity with no survival impact, surgeons have preferred laparoscopic spleen-preserving splenic hilar lymphadenectomy (LSPL) for advanced tumors without metastasis to splenic hilar nodes or invasion to the greater curvature of the stomach, and reports with LSPL have been increasing rather than LTG with splenectomy. In this paper, recent reports with laparoscopic splenic hilar lymphadenectomy were reviewed.

    Living with advanced cancer can present an overwhelming challenge. It may impact the everyday life of the individual with respect to an array of psychological, physical, social, and existential issues. We focus on ways in which people with advanced cancer experience and use their engagement in daily activities when confronting nearing death. Through a phenomenological analysis based on Heidegger's thinking, we illuminate the complexities of "being toward death" and the human striving for authentic being through engagement in daily living. The main findings demonstrate how sensory experiences support being through an appreciation of everyday aesthetics. Furthermore, the making of material things was identified as a means to express the value of self and others in relation to the involved individual's past, present, and future.

    Survival outcome of locally advanced pancreatic cancer has been poor and little is known about prognostic factors of the disease, especially in locally advanced cases treated with concurrent chemoradiation. This study was to analyze overall survival and prognostic factors of patients treated with concurrent chemoradiotherapy (CCRT) in locally advanced pancreatic cancer. Medical records of 34 patients diagnosed with unresectable pancreatic cancer and treated with definitive CCRT, from December 2003 to December 2012, were reviewed. Median prescribed radiation dose was 50.4 Gy (range, 41.4 to 55.8 Gy), once daily, five times per week, 1.8 to 3 Gy per fraction. With a mean follow-up of 10 months (range, 0 to 49 months), median overall survival was 9 months. The 1- and 2-year survival rates were 40% and 10%, respectively. Median and mean time to progression were 5 and 7 months, respectively. Prognostic parameters related to overall survival were post-CCRT CA19-9 (p = 0.02), the Eastern Cooperative Oncology Group (ECOG) status (p < 0.01), and radiation dose (p = 0.04) according to univariate analysis. In multivariate analysis, post-CCRT CA19-9 value below 180 U/mL and ECOG status 0 or 1 were statistically significant independent prognostic factors associated with improved overall survival (p < 0.01 and p = 0.02, respectively). Overall treatment results in locally advanced pancreatic cancer are relatively poor and few improvements have been accomplished in the past decades. Post-treatment CA19-9 below 180 U/mL and ECOG performance status 0 and 1 were significantly associated with an improved overall survival.

    2013-12-01

    Cancer is both highly feared and highly newsworthy, and there is a robust body of research documenting the content and effects of cancer news coverage on health behaviors and policy. Recent years have witnessed ongoing, transformative shifts in American journalism alongside rapid advances in communication technology and the public information environment. These changes create a pressing need to consider a new set of research questions, sampling strategies, measurement techniques, and theories of media effects to ensure continued relevance and adaptation of communication research to address critical cancer control concerns. This paper begins by briefly reviewing what we know about the role of cancer news in shaping cancer-related beliefs, attitudes, behaviors, and policies. We then outline challenges and opportunities, both theoretical and methodological, posed by the rapidly changing news media environment and the nature of audience engagement. We organize our discussion around three major shifts associated with the emerging news media environment as it relates to health communication: 1) speed and dynamism of news diffusion, 2) increased narrowcasting of media content for specialized audiences, and 3) broadened participation in shaping media content. In so doing, we articulate a set of questions for future theory and research, in an effort to catalyze innovative communication scholarship to improve cancer prevention and control.

    The aim of investigation is to improve surgical treatment of patients with locally advanced pelvic cancer. The basis of investigation is 186 patients with locally advanced pelvic cancer. The average age of patients is 65.2 ± 5.2 years (from 43.7 to 88.4 years). Among them are 112 women and 74 men. In the period from 2007 to 2015 they were carried out combined (101 patients) and expanded (85 patients) surgical intervention in the department of naval surgery of the Military medical academy after S.M.Kirov. Pelvic evisceration was performed in 63 cases. Both patients were performed isolated vascular hyperthermic chemical pelvic perfusion. Indications for plastic surgery of peritoneum pelvic were: total infralitoral pelvic evisceration (9 patients), dorsal infralitoral pelvic evisceration (11 cases) and expanded abdominoperineal rectum extirpation (34 patients). Plastic surgery with autogenouse tissues was performed to 43 patients, with reticulate explants--to 11 patients. The rate of postoperative complications was 40.2%. The rate of postoperative lethality was 8%. Expanded and combined operations of pelvic at patients with locally advanced cancer without absolute contra-indications can be performed irrespective of age. Plastic surgery of peritoneum pelvic after total and dorsal infralitoral pelvic evisceration and expanded abdominoperineal rectum extirpation indicated in all cases. The easiest method is plastic surgery with greater omentum or peritoneum pelvic. Plastic surgery with reticulate explants is performed when autoplastic is impossible.

    Nineteen patients with locally advanced pancreatic cancer and one patient with islet cell cancer were treated with 1700-1500 neutron rad alone or in combination with 5-fluorouracil to exploit the theoretic advantages of higher linear energy of transfer, and lower oxygen enhancement ratio of neutrons. Only 5 of 14 (36%) obtained partial tumor regression. The median survival for all patients with pancreatic cancer was 6 months, which is less than that reported with 5-fluorouracil and conventional photon irradiation. Gastrointestinal toxicity was considerable; hemorhagic gastritis in five patients, colitis in two and esophagitis in one. One patient developed radiation myelitis. We therefore, caution any enthusiasm for this modality of therapy until clear evidence of a therapeutic advantage over photon therapy is demonstrated in controlled clinical trials

High-intensity focused ultrasound (HIFU is becoming an emerging approach of noninvasively ablating solid tumor in clinics. A variety of solid tumors have been tried on thousands of patients in the last fifteen years with great success. The principle, mechanism, and clinical outcome of HIFU were introduced first. All 3022 clinical cases of HIFU treatment for the advanced pancreatic cancer alone or in combination with chemotherapy or radiotherapy in 241 published papers were reviewed and summarized for its efficacy, pain relief, clinical benefit rate, survival, Karnofsky performance scale (KPS score, changes in tumor size, occurrence of echogenicity, serum level, diagnostic assessment of outcome, and associated complications. Immune response induced by HIFU ablation may become an effective way of cancer treatment. Comments for a better outcome and current challenges of HIFU technology are also covered.

    To evaluate treatment outcome of patients with high risk locally advanced gastric cancer after postoperative chemoradiotherapy. Between May 2003 and May 2012, thirteen patients who underwent postoperative chemoradiotherapy for gastric cancer with resection margin involvement or adjacent structure invasion were retrospectively analyzed. Concurrent chemotherapy was administered in 10 patients. Median dose of radiation was 50.4 Gy (range, 45 to 55.8 Gy). The median follow-up duration for surviving patients was 48 months (range, 5 to 108 months). The 5-year overall survival rate was 42% and the 5-year disease-free survival rate was 28%. Major pattern of failure was peritoneal seeding with 46%. Loco-regional recurrence was reported in only one patient. Grade 2 or higher gastrointestinal toxicity occurred in 54% of the patients. However, there was only one patient with higher than grade 3 toxicity. Despite reported suggested role of adjuvant radiotherapy with combination chemotherapy in gastric cancer, only very small portion of the patients underwent the treatment. Results from this study show that postoperative chemoradiotherapy provided excellent locoregional control with acceptable and manageable treatment related toxicity in patients with high risk locally advanced gastric cancer. Thus, postoperative chemoradiotherapy may improve treatment result in terms of locoregional control in these high risk patients. However, as these findings are based on small series, validation with larger cohort is suggested.

    Locally advanced colon cancer with direct abdominal wall and skin invasion is an extremely rare finding with most data being derived from case reports, historical autopsy-based or single-center retrospective studies. We present a unique case of a colon cancer with direct cutaneous invasion and colocutaneous fistulization. Eighty-six year old Caucasian female with multiple comorbidities, referred to Surgical Consultation due to ulcerated skin lesion in the abdomen. She had a long-standing large umbilical hernia but with no previous episodes of incarceration or occlusive symptoms. She denied any digestive or constitutional symptoms. Physical examination showed a large non-reducible umbilical hernia, with an associated painless firm mass within the hernia sac and cutaneous ulcerated growth. Colonoscopy revealed transverse colon cancer (endoscopic biopsy of the tumor and skin punch biopsy confirmed adenocarcinoma of the colon). Computed tomography showed a tumoral mass within the umbilical hernia, with cutaneous infiltration and enlarged regional lymph nodes. Rapid local progression led to colocutaneous fistula with total fecal diversion. We performed an extended right hemicolectomy with en bloc excision of the hernia sac and infiltrating cutaneous mass. In the current era of widespread use of screening colonoscopies, initial diagnosis of locally advanced colon cancer is decreasing. However, this unique case presented an opportunity to recall the advantages of multivisceral resections.

    Full Text Available Active anticancer molecules have been searched from natural products; many drugs were developed from either natural products or their derivatives following the conventional pharmaceutical paradigm of drug discovery. However, the advances in the knowledge of cancer biology have led to personalized medicine using molecular-targeted agents which create new paradigm. Clinical benefit is dependent on individual biomarker and overall survival is prolonged through cytostatic rather than cytotoxic effects to cancer cell. Therefore, a different approach is needed from the single lead compound screening model based on cytotoxicity. In our experience, the Rhus verniciflua stoke (RVS extract traditionally used for cancer treatment is beneficial to some advanced cancer patients though it is herbal extract not single compound, and low cytotoxic in vitro. The standardized RVS extract's action mechanisms as well as clinical outcomes are reviewed here. We hope that these preliminary results would stimulate different investigation in natural products from conventional chemicals.

    Ovarian cancer is the sixth most common cancer among women. In addition to diagnosis and staging, primary surgery is performed to achieve optimal cytoreduction (surgical efforts aimed at removing the bulk of the tumour) as the amount of residual tumour is one of the most important prognostic factors for survival of women with epithelial ovarian cancer. An optimal outcome of cytoreductive surgery remains a subject of controversy to many practising gynae-oncologists. The Gynaecologic Oncology group (GOG) currently defines 'optimal' as having residual tumour nodules each measuring 1 cm or less in maximum diameter, with complete cytoreduction (microscopic disease) being the ideal surgical outcome. Although the size of residual tumour masses after surgery has been shown to be an important prognostic factor for advanced ovarian cancer, it is unclear whether it is the surgical procedure that is directly responsible for the superior outcome that is associated with less residual disease. To evaluate the effectiveness and safety of optimal primary cytoreductive surgery for women with surgically staged advanced epithelial ovarian cancer (stages III and IV).To assess the impact of various residual tumour sizes, over a range between zero and 2 cm, on overall survival. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2010, Issue 3) and the Cochrane Gynaecological Cancer Review Group Trials Register, MEDLINE and EMBASE (up to August 2010). We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field. Retrospective data on residual disease from randomised controlled trials (RCTs) or prospective and retrospective observational studies which included a multivariate analysis of 100 or more adult women with surgically staged advanced epithelial ovarian cancer and who underwent primary cytoreductive surgery followed by adjuvant platinum

    Full Text Available Introduction. Hemolytic uremic syndrome (HUS is characterized by endothelial dysfunction, consumption thrombocytopenia, microangiopathic hemolytic anemia, and acute renal failure. HUS generally has a dismal prognosis, except when associated with gastroenteritis caused by verotoxin-producing bacteria. Cancer associated HUS is uncommon, and there are only scarce reports on prostate cancer presenting with HUS. Case Presentation. A 72-year-old man presented to the emergency department with oliguria, hematuria, and hematemesis. Clinical evaluation revealed acute renal failure, hemolysis, normal blood-clotting studies, and prostate-specific antigen value of 1000 ng/mL. The patient was started on hemodialysis, ultrafiltration with plasma exchange, and androgen blockade with bicalutamide and completely recovered from HUS. The authors review the 14 published cases on this association. Conclusion. The association of HUS and prostate cancer occurs more frequently in patients with high-grade, clinically advanced prostate cancer. When readily recognized and appropriately treated, HUS does not seem to worsen prognosis in prostate cancer patients.

    Purpose: Capecitabine (Xeloda) is a new orally administered fluoropyrimidine carbamate that was rationally designed to exert its effect by tumor-selective activation. We attempted to evaluate the efficacy and toxicity of preoperative chemoradiation using capecitabine in locally advanced rectal cancer. Methods and Materials: Between July 1999 and March 2001, 45 patients with locally advanced rectal cancer (cT3/T4 or N+) were treated with preoperative chemoradiation. Radiation of 45 Gy/25 fractions was delivered to the pelvis, followed by a 5.4 Gy/3 fractions boost to the primary tumor. Chemotherapy was administered concurrent with radiotherapy and consisted of 2 cycles of 14-day oral capecitabine (1650 mg/m 2 /day) and leucovorin (20 mg/m 2 /day), each of which was followed by a 7-day rest period. Surgery was performed 6 weeks after the completion of chemoradiation. Results: Thirty-eight patients received definitive surgery. Primary tumor and node downstaging occurred in 63% and 90% of patients, respectively. The overall downstaging rate, including both primary tumor and nodes, was 84%. A pathologic complete response was achieved in 31% of patients. Twenty-one patients had tumors located initially 5 cm or less from the anal verge; among the 18 treated with surgery, 72% received sphincter-preserving surgery. No Grade 3 or 4 hematologic toxicities developed. Other Grade 3 toxicities were as follows: hand-foot syndrome (7%), fatigue (4%), diarrhea (4%), and radiation dermatitis (2%). Conclusion: These preliminary results suggest that preoperative chemoradiation with capecitabine is a safe, well-tolerated, and effective neoadjuvant treatment modality for locally advanced rectal cancer. In addition, this preoperative treatment has a considerable downstaging effect on the tumor and can increase the possibility of sphincter preservation in distal rectal cancer

    While tumour-initiating cells (TIC) have been reported across solid tumours, there is dearth of data regarding TICs and radiation response in cervical cancer. From October, 2013- July, 2015 patients with locally advanced cervical cancer were included. Pretreatment biopsy was obtained. IHC was performed for SOX-2,OCT-4, Nanog (ESC), CD44 and Podoplanin (TIC). Semiquantitative scoring was used for IHC. All patients received uniform concurrent chemoradiation and brachytherapy. On follow up, local control and distant relapse was recorded

    Dignity therapy is a psychosocial intervention that has been used primarily at the end of life to improve quality of life and other patient outcomes, but many individuals are unable to complete it due to health decline and death. The purpose of this study was to identify what individuals with advanced pancreatic or lung cancer with limited life expectancy, undergoing active cancer treatment describe during the dignity therapy intervention as important to them when not immediately facing end of life. Twenty patients undergoing chemotherapy for advanced cancer participated in a dignity therapy intervention study. Initial interviews were analyzed using descriptive content analysis. Family provided the overall context and background for emerging themes of defining events, accomplishments, and God's plan, which led to lessons learned, and resulted in messages of hope. Interviews were often autobiographical in nature and contained much reminiscence, consistent with dignity therapy's intent. Few participants spoke about their cancer diagnoses during the interview. This study adds unique insight into the use of dignity therapy for those still receiving active cancer treatment, different from work by others in which it was offered only at end of life. As part of supportive care, clinicians need to validate the importance of family to those with advanced cancer and to provide opportunities for patients to share what they have learned throughout life and to impart messages of hope to those closest to them.

    Full Text Available The majority of pancreatic cancer diagnoses are made at the advanced stage and when metastasis has already occurred, and the 1- and 5-year survival rates are extremely low. Cemcitabine remains the most frequently applied treatment option, yet the most effective chemotherapeutic agents and combinations with multiple agents and/or radiotherapy only marginally improve patient survival and may even establish an environment conducive to cancer cells with stem cell-like characteristics. An alternative treatment modality, cryoablation, is available and has been applied at our institute to patients with unresectable pancreatic cancer since 2001. In this article, we present our collective experience with patient outcome using cryoablation, alone or combined with other treatment modalities such as brachytherapy (125iodine seed implantation. The overall outcomes have been encouraging, suggesting that comprehensive therapy including cryoablation may prolong the survival of patients with advanced or metastatic pancreatic cancer, and we are achieving particular success with a novel combination of percutaneous cryoablation, cancer microvascular intervention with 125iodine seed implantation, and combined immunotherapy (3C applied using an individualized patient strategy (P. The 1- through 10-year survival rates of 145 patients treated with the so-called “3C+P model” are presented in support of this new strategy as a promising new treatment for advanced and metastatic cancer

    Over 3 years, concurrent chemoradiotherapy was performed in 16 patients with advanced esophageal cancer (clinical Stage IV) and suspected noncurative resection. The subjects were {>=}A3 or N3, or were stage IV with distant metastasis on preoperative diagnosis. Two courses of 5FU and CDDP were given with concurrent radiotherapy. The predominant side effects were nausea, vomiting and anorexia. Mild or moderate leukopenia also occurred. The response was complete remission (CR) in two patients, partial remission (PR) in eight, minor response (MR) in two, no change (NC) in two and progressive disease (PD) in two. The overall response rate was 62.5%. Esophagectomy was performed in four patients (histological stage II in one, stage III in one, and stage IV in two). Two of 4 resected patients are alive (33.8 months), while the other died of unrelated causes. One of the 6 non-resected PR patients has survived for 18 months, but all other patients died of cancer within nine months of starting treatment. The survival rate of 16 patients undergoing chemoradiotherapy was 16.7% at one and two years. Thus, chemoradiotherapy may improve the prognosis of advanced esophageal cancer with suspected noncurative resection by increasing the response rate and the curative resection rate. (author)

    Full Text Available Breast cancer (BC is the most common malignancy in women. It is classified into a few major molecular subtypes according to hormone and growth factor receptor expression. Over the past few years, substantial advances have been made in the discovery of new drugs for treating BC. Improved understanding of the biologic heterogeneity of BC has allowed the development of more effective and individualized approach to treatment. In this review, we provide an update about the current treatment strategy and discuss the various emerging novel therapies for the major molecular subtypes of BC. A brief account of the clinical development of inhibitors of poly(ADP-ribose polymerase, cyclin-dependent kinases 4 and 6, phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin pathway, histone deacetylation, multi-targeting tyrosine kinases, and immune checkpoints for personalized treatment of BC is included. However, no targeted drug has been approved for the most aggressive subtype—triple negative breast cancer (TNBC. Thus, we discuss the heterogeneity of TNBC and how molecular subtyping of TNBC may help drug discovery for this deadly disease. The emergence of drug resistance also poses threat to the successful development of targeted therapy in various molecular subtypes of BC. New clinical trials should incorporate advanced methods to identify changes induced by drug treatment, which may be associated with the upregulation of compensatory signaling pathways in drug resistant cancer cells.

    The Asia-Pacific Colorectal Screening (APCS) score based on age, gender, family history, and smoking is useful to predict advanced colorectal neoplasia (ACN) in asymptomatic Asian subjects. To evaluate the factors in addition to those of APCS associated with ACN colonoscopic findings. Data from 5,220 asymptomatic subjects aged between 50 and 70 years who underwent screening colonoscopy in a community center between 2008 and 2012 were analyzed. One binary logistic regression analysis was conducted in 2013 with the presence of ACN or cancer as the outcome, controlling for APCS score, alcohol consumption, BMI, hypertension, and other chronic diseases as independent variables. The average participant age was 57.7 years (SD=4.9) and 47.5% were men. Advanced neoplasms or cancers were identified at colonoscopy in 5.6% of all screening participants. From multivariate regression analysis, APCS score≥4 (adjusted OR [AOR]=1.74, 95% CI=1.34, 2.25, pstatistic of APCS score alone was 0.560 (95% CI=0.524, 0.595, p=0.001) and that of APCS score plus BMI, hypertension, and alcohol consumption was 0.613 (95% CI=0.578, 0.648, p<0.001). Alcohol consumption, hypertension, and BMI are independent predictors of ACN, which could be incorporated into the APCS for prioritizing Asian asymptomatic subjects for colorectal cancer screening.

    The laryngeal functions in patients with laryngeal or hypopharyngeal cancer treated with concurrent chemoradiotherapy (CCRT) were evaluated. We reviewed the records of 32 patients with resectable stage II to IV squamous cell carcinoma of the larynx or hypopharynx treated with CCRT as a initial treatment between October 1998 and September 2003. A questionnaire survey and measurements of maximum phonation time, GRBAS and range of voice/speaking fundamental frequency were performed, and the method of food intake in the swallowing ability scale and the presence of tracheostoma were assessed for evaluating laryngeal functions after CCRT. After CCRT for laryngeal or hypopharyngeal cancer, the phonatory functions appeared to be preserved in 75% of the patients in terms of sustainability; however, there were some cases presenting hoarseness and narrowed range of voice. Oral intake was possible in most cases (97%) without a history of aspiration pneumonia. In 2 cases, permanent tracheostoma had to be retained. It was concluded that laryngeal functions could be preserved in most cases after CCRT, though the tracheostoma might not be closed in some patients with laryngeal cancer. (author)

    Many physicians avoid advance care planning (ACP) discussions because they worry such conversations will lead to psychological distress. To investigate whether engaging in ACP using online planning tools adversely affects hope, hopelessness, or anxiety among patients with advanced cancer. Patients with advanced cancer and an estimated survival of two years or less (Intervention group) and a Control group were recruited at a tertiary care academic medical center (2007-2012) to engage in ACP using an online decision aid ("Making Your Wishes Known"). Pre/post and between-group comparisons were made, including hope (Herth Hope Index), hopelessness (Beck Hopelessness Scale), and anxiety (State Trait Anxiety Inventory). Secondary outcomes included ACP knowledge, self-determination, and satisfaction. A total of 200 individuals completed the study. After engaging in ACP, there was no decline in hope or increase in hopelessness in either the Control or Intervention group. Anxiety was likewise unchanged in the Control group but decreased slightly in the Intervention group. Knowledge of ACP (% correct answers) increased in both the groups, but more so in the Intervention group (13% increase vs. 4%; P<0.01). Self-determination increased slightly in both groups, and satisfaction with the ACP process was greater (P<0.01) in the Intervention than Control group. Engaging in ACP with online planning tools increases knowledge without diminishing hope, increasing hopelessness, or inducing anxiety in patients with advanced cancer. Physicians need not avoid ACP out of concern for adversely affecting patients' psychological well-being. Copyright © 2015 American Academy of Hospice and Palliative Medicine.

    The aim of this outcome study was to evaluate the management of advanced pancreatic cancer in a real-world clinical practice; few such experiences have been reported in the literature. A retrospective analysis was performed of all consecutive patients with advanced pancreatic ductal adenocarcinoma followed at our medical oncology unit between January 2003 and December 2013. We evaluated 78 patients, mostly with metastatic disease (64.1%). Median follow-up was 10.77 months, by which time 74 patients (94.9%) had died. Median overall survival was 8.29 months. Median age was 67 years. In univariate analysis, pain at onset (p = 0.020), ECOG performance status (p<0.001), stage (p = 0.047), first-line chemotherapy (p<0.001), second-line chemotherapy (p<0.001) and weight loss at diagnosis (p = 0.029) were factors that had an impact on overall survival. In multivariate analysis, the presence of pain at onset (p = 0.043), stage (p = 0.003) and second-line chemotherapy (p = 0.004) were confirmed as independent prognostic factors. Our data, derived from daily clinical practice, confirmed advanced pancreatic cancer as an aggressive malignant disease with a very short expected survival. Second-line treatment seems to provide an advantage in terms of overall survival in patients who showed a partial response as their best response to first-line treatment.

    Laryngeal reconstruction is needed to preserve laryngeal function in patients who have undergone extensive vertical or frontal partial laryngectomy. However, the procedure remains a difficult challenge. Several reconstruction techniques have been described, but these techniques pose risks of complications such as laryngeal stenosis. This study aimed to evaluate the postoperative course and functional outcomes of a new technique that combined a muscle-pedicle hyoid bone and a thyrohyoid flap during laryngeal reconstruction after tumor resection. Four patients underwent extensive vertical partial or frontal partial laryngectomy for cancer. After tumor resection, laryngeal reconstruction was performed using the proposed technique. Postoperative recovery time, complications, and oncologic results were evaluated. The four patients were successfully treated with the proposed technique. No dyspnea, dysphagia, or death occurred during the postoperative course. Decannulation was performed after a median of 3 days. The average postoperative hospital stay was 7 days. Short-term postoperative functional recovery was normal. No laryngeal stenosis or tumor recurrence was observed in any of the four patients after a follow-up period of more than 24 months. The combination of the muscle-pedicle hyoid bone and the thyrohyoid flap is a reliable procedure for laryngeal reconstruction after extensive vertical partial or frontal partial laryngectomy

    Full Text Available Objectives: The purpose of this study is to report a case series of advanced cancer patients whose cancer pain was relieved by using autonomic nerve pharmacopuncture (ANP treatment. ANP is a subcutaneous injection therapy of mountain ginseng pharmacopuncture (MGP along the acupoints on the spine (Hua-Tuo-Jia-Ji-Xue; 0.5 cun lateral to the lower border of the spinous processes of vertebrae to enhance the immune system and to balance autonomic nerve function. Methods: Patients with three different types of cancer (gastric cancer, lung cancer, colon cancer with distant metastases with cancer pain were treated with ANP. 1 mL of MGP was injected into the bilateral Hua-Tuo-Jia-Ji-Xue on the T1-L5 sites (total 12 ─ 20 mL injection of each patient’s dorsum by using the principle of symptom differentiation. During ANP treatment, the visual analogue scale (VAS for pain was used to assess their levels of cancer pain; also, the dosage and the frequency of analgesic use were measured. Results: The cancer pain levels of all three patients improved with treatment using ANP. The VAS scores of the three patients decreased as the treatment progressed. The dosage and the frequency of analgesics also gradually decreased during the treatment period. Significantly, no related adverse events were found. Conclusion: ANP has shown benefit in controlling cancer pain for the three different types of cancer investigated in this study and in reducing the dosage and the frequency of analgesics. ANP is expected to be beneficial for reducing cancer pain and, thus, to be a promising new treatment for cancer pain.

    We assess the clinical utility of a unique simultaneous fingerprint (FP) (i.e., 800-1800 cm−1) and high-wavenumber (HW) (i.e., 2800-3600 cm−1) fiber-optic Raman spectroscopy for in vivo diagnosis of laryngeal cancer at endoscopy. A total of 2124 high-quality in vivo FP/HW Raman spectra (normal = 1321; cancer = 581) were acquired from 101 tissue sites (normal = 71; cancer = 30) of 60 patients (normal = 44; cancer = 16) undergoing routine endoscopic examination. FP/HW Raman spectra differ significantly between normal and cancerous laryngeal tissue that could be attributed to changes of proteins, lipids, nucleic acids, and the bound water content in the larynx. Partial least squares-discriminant analysis and leave-one tissue site-out, cross-validation were employed on the in vivo FP/HW tissue Raman spectra acquired, yielding a diagnostic accuracy of 91.1% (sensitivity: 93.3% (28/30); specificity: 90.1% (64/71)) for laryngeal cancer identification, which is superior to using either FP (accuracy: 86.1%; sensitivity: 86.7% (26/30); specificity: 85.9% (61/71)) or HW (accuracy: 84.2%; sensitivity: 76.7% (23/30); specificity: 87.3% (62/71)) Raman technique alone. Further receiver operating characteristic analysis reconfirms the best performance of the simultaneous FP/HW Raman technique for laryngeal cancer diagnosis. We demonstrate for the first time that the simultaneous FP/HW Raman spectroscopy technique can be used for improving real-time in vivo diagnosis of laryngeal carcinoma during endoscopic examination.

    Full Text Available The broad application of low-dose computed tomography screening has resulted in the detection of many more cases of early lung cancer than ever before in modern history. Recent advances in the management of early-stage non-small cell lung cancer have focused on making therapy less traumatic, enhancing recovery, and preserving lung function. In this review, we discuss several new modalities associated with minimally invasive surgery for lung cancer. Firstly, less lung parenchyma resection via sublobar resection has become an acceptable alternative to lobectomy in patients with tumors less than 2 cm in size or with poor cardiopulmonary reserve. Secondly, thoracoscopic surgery using a single-portal or needlescopic approach to decrease chest wall trauma is becoming common practice. Thirdly, less invasive anesthesia, using nonintubated techniques, is feasible and safe and is associated with fewer intubation- and ventilator-associated complications. Fourthly, preoperative or intraoperative image-guided localization is an effective modality for identifying small and deep nodules during thoracoscopic surgery.

    Full Text Available Modern oncotherapy approaches are based on inducing controlled apoptosis in tumor cells. Although a number of apoptosis-induction approaches are available, site-specific delivery of therapeutic agents still remain the biggest hurdle in achieving the desired cancer treatment benefit. Additionally, systemic treatment-induced toxicity remains a major limiting factor in chemotherapy. To specifically address drug-accessibility and chemotherapy side effects, oncolytic virotherapy (OV has emerged as a novel cancer treatment alternative. In OV, recombinant viruses with higher replication capacity and stronger lytic properties are being considered for tumor cell-targeting and subsequent cell lysing. Successful application of OVs lies in achieving strict tumor-specific tropism called oncotropism, which is contingent upon the biophysical interactions of tumor cell surface receptors with viral receptors and subsequent replication of oncolytic viruses in cancer cells. In this direction, few viral vector platforms have been developed and some of these have entered pre-clinical/clinical trials. Among these, the Vesicular stomatitis virus (VSV-based platform shows high promise, as it is not pathogenic to humans. Further, modern molecular biology techniques such as reverse genetics tools have favorably advanced this field by creating efficient recombinant VSVs for OV; some have entered into clinical trials. In this review, we discuss the current status of VSV based oncotherapy, challenges, and future perspectives regarding its therapeutic applications in the cancer treatment.

    The aim of the present study was to retrospectively evaluate the incidence of hypothyroidism in locally advanced head and neck cancer patients who received radiotherapy (RT) either with or without neck dissection. From January 2000 to December 2005, 115 patients with locally advanced head and neck cancer and who received definitive RT or postoperative RT including standard anterior low-neck field were recruited to be part of this study. Nineteen patients had undergone ipsilateral neck dissection, whereas, 18 patients underwent bilateral neck dissection, and 78 patients were received RT alone. Patients' ages ranged from 28 to 85 years (median, 59 years) and there were a total of 73 male and 42 female patients. The primary tumor sites were the oral cavity, oropharynx, hypopharynx, larynx, and other sites in 18, 40, 28, 22 and 7 patients, respectively. Radiation dose to the thyroid gland ranged from 44 Gy to 66 Gy with a median dose of 50 Gy. Follow-up time ranged from 2 to 91 months, with a median of 29 months. The 1- and 3- year incidence of hypothyroidism was 28.7% (33 patients) and 33.0% (38 patients), respectively. The median time to detection of hypothyroidism was 8.5 months (range, 0 to 36 months). A univariate analysis revealed that neck node dissection was a risk factor for hypothyroidism (p=0.037). However, no factor was statistically significant from the results of a multivariate analysis. Patients treated for advanced head and neck cancer with radiotherapy with or without neck dissection will develop hypothyroidism. It is important to check the thyroid function periodically in these patients especially with the risk factor of neck node dissection.

    The aim of the present study was to retrospectively evaluate the incidence of hypothyroidism in locally advanced head and neck cancer patients who received radiotherapy (RT) either with or without neck dissection. From January 2000 to December 2005, 115 patients with locally advanced head and neck cancer and who received definitive RT or postoperative RT including standard anterior low-neck field were recruited to be part of this study. Nineteen patients had undergone ipsilateral neck dissection, whereas, 18 patients underwent bilateral neck dissection, and 78 patients were received RT alone. Patients' ages ranged from 28 to 85 years (median, 59 years) and there were a total of 73 male and 42 female patients. The primary tumor sites were the oral cavity, oropharynx, hypopharynx, larynx, and other sites in 18, 40, 28, 22 and 7 patients, respectively. Radiation dose to the thyroid gland ranged from 44 Gy to 66 Gy with a median dose of 50 Gy. Follow-up time ranged from 2 to 91 months, with a median of 29 months. The 1- and 3- year incidence of hypothyroidism was 28.7% (33 patients) and 33.0% (38 patients), respectively. The median time to detection of hypothyroidism was 8.5 months (range, 0 to 36 months). A univariate analysis revealed that neck node dissection was a risk factor for hypothyroidism (p=0.037). However, no factor was statistically significant from the results of a multivariate analysis. Patients treated for advanced head and neck cancer with radiotherapy with or without neck dissection will develop hypothyroidism. It is important to check the thyroid function periodically in these patients especially with the risk factor of neck node dissection.

    The aim of this study is to examine the therapeutic effects and adverse events of preoperative chemoradiation therapy (CRT) for locally advanced rectal cancer in different radiation doses and fractions. A total of 142 consecutive patients with locally advanced (cT3-4 and/or cN1-2) adenocarcinoma of the rectum were treated with preoperative CRT and were operated radically. 121 patients with resectable cT3 or N1-2 rectal adenocarcinoma were assigned to receive pelvic radiation with single fractions of 2.5 Gy twice daily to a total dose of 25 Gy (Short CRT). Surgery was undergone within two weeks. 21 patients with clinical unresectable or marginally resectable cT4 rectal cancer were assigned to receive preoperative pelvic radiation therapy 45 to 50.4 Gy at 1.8 Gy per day. Surgery was performed 6 to 8 weeks after completion of neoadjuvant therapy (Long CRT). We examined retrospectively the preoperative therapeutic effect and adverse event of Short CRT and Long CRT. Short CRT; Overall R0 resection rate was 98%. Anus preserving rate was 95%. pCR rate was 5%. Median follow-up was 62 months. The actuarial 5-year-local-control rate was 94%. Overall survival for 5 years was 92%. Long neoadjuvant chemoradiation therapy (NCRT); Overall R0 resection rate was 90%. Anus preserving rate was 86%. pCR rate was 24%. Median follow-up was 60 months. The actuarial 5-year-local-control rate was 88%. Overall survival rate for 5 years was 88%. Radiation related adverse event such as pelvic infection and skin trouble was significantly higher in the long CRT group. Local control in primarily resectable rectal cancer after short chemoradiation was excellent. Long chemoradiation for unresectable or marginal cT4 rectum cancer was higher response ratio, but induced more radiation related adverse event than short course CRT. (author)

    Cytoreductive surgery and chemotherapy are the mainstay for the treatment of advanced epithelial ovarian cancer. In order to minimize the tumour burden before chemotherapy, cytoreductive surgery is usually performed first. The importance of the amount of residual disease as the main prognostic factor for patients suffering from advanced disease has been almost universally accepted even in the absence of prospective randomized trials addressing the benefit of cytoreductive surgery. In the last decade, the value of debulking surgery after induction chemotherapy - interval debulking surgery, IDS - has been widely debated, especially after the completion of a prospective randomized study from the EORTC addressing the introduction of a surgical procedure with debulking intent preceded and followed by cytoreductive chemotherapy. The rationale of such a strategy in the context of the primary treatment of advanced ovarian cancer lies in a higher cytoreductibility to the 'optimal' status forwarded, and possibly facilitated, by chemotherapy. The results demonstrated a prolongation of both progression-free survival and median survival in favour of patients randomized to IDS (5 and 6 months, respectively). Multivariate analysis revealed IDS to be an independent prognostic factor which reduced the risk of death by 33% at 3 years and by 48% in subsequent re-evaluation after more than 6 years of observation. Despite the above, results have been questioned by many, leading the GOG to perform a similar study which has been concluded very recently. Nevertheless, the main concern regarding the application of IDS in all instances relates to the morbidity of two major surgical procedures integrated within a short period during which cytotoxic chemotherapy is also administered. Neoadjuvant chemotherapy has been recently proposed to avoid a non-useful surgical procedure in patients considered 'optimally unresectable' after diagnosis of advanced ovarian cancer.

    Full Text Available Definitive radiochemotherapy is the standard treatment for many patients with locally advanced nonsmall cell lung cancer (NSCLC. Treatment outcomes have improved over the last decades. Several treatment regimens have been shown effective and safe. This review summarises the results of significant studies between 1996 and 2015 on concomitant and sequential radiochemotherapy regimens and radiation dose per fraction. Beside therapy regimens, optimised radiotherapy planning is indispensable to improve outcome and minimise radiation-induced toxicity. An insight into the rationale of radiotherapy planning for stage III NSCLC is also provided.

    Photodynamic therapy (PDT) based upon the use of light and photosensitizers (PSs) has been used as a novel treatment approach for a variety of tumors. It, however, has several major limitations in the clinic: poor water solubility, long-term phototoxicity, low tumor targeting efficacy, and limited light penetration. With advances in nanotechnology, materials science, and clinical interventional imaging procedures, various smart-PSs have been developed for improving their cancer-therapeutic efficacy while reducing the adverse effects. Here, we briefly review state-of-the-art smart-PSs and discuss the future directions of PDT technology.

    Chyle fistula (CF) is a rare but challenging condition for the surgeon and the patient's health. A retrospective review of single surgeon's case load in a 12-year period is presented, reviewing the case of those patients presenting with a CF. Three patients were found during this study period from more than 1,050 surgeries performed due to thyroid cancer. Patients underwent extensive lymph node dissection for advanced, metastatic and infiltrative disease. In all patients, a long hospital stay and surgical re-interventions were required. A description of the management of CF is presented along with a review of current Literature.

    Full Text Available Migratory venous thrombosis is a manifestation of the rare paraneoplastic syndrome in patients with malignant neoplasms. The paper describes successful surgical treatment in a young patient with a colon tumor associated with Trousseau’s syndrome. The latter manifesting itself as ischemia forced urgent surgeons to amputate the lower third of the left leg. Locally advanced transverse colon cancer spreading to the great vessels was subsequently diagnosed. All paraneoplastic manifestations disappeared after tumor removal. The patient was professionally given surgical, anesthesiological, and resuscitative aids that not only improved his quality of life, but also gave the chance to prolong it.

    Laryngeal myasthenia gravis is a relatively rare variant of myasthenia gravis. A vast portion of patients with initial laryngeal myasthenia gravis develop involvement of ocular and/or extra-ocular muscles during the years after symptom onset although a minority of laryngeal myasthenia gravis patients continues to have isolated laryngeal muscle involvement for several years. We present a 58-year-old woman with recurrent episodic isolated dysphonia (associated with diffuse bilateral vocal cord paresis on laryngoscopy) since the age of 32. Dysphonia became permanent since 6 months. A diagnosis of laryngeal myasthenia gravis was made based on abnormal single-fiber electromyography and spectacular response to pyridostigmine treatment. Repetitive nerve stimulation was normal and anti-acetylcholine receptor and anti-muscle specific tyrosine kinase antibodies were absent. This case shows that laryngeal myasthenia gravis can be isolated during 26 years of follow-up. We propose that even when myasthenia gravis seems unlikely as underlying mechanism of isolated dysphonia (because of lack of antibodies, normal repetitive nerve stimulation, and absence of extra-laryngeal involvement after years of follow-up), single-fiber electromyography should be performed and myasthenia gravis treatment should be tried.

    Purpose People frequently present to voice clinics with complaints of irritating laryngeal sensations. Clinicians attempt to reduce the irritating sensations and their common sequela, coughing and throat clearing, by advocating for techniques that remove the irritation with less harm to the vocal fold tissue. Despite the prevalence of patients with these complaints, it is not known if the less harmful techniques recommended by clinicians are effective at clearing irritating laryngeal sensations or that irritating laryngeal sensations are, in fact, more frequent in people with voice disorders than people without voice disorders. Method Assessments of participant reported laryngeal sensation, pre- and post- clearing task, were obtained from 22 people with and 24 people without a voice disorder. Six clearing tasks were used to preliminarily evaluate the differing effects of tasks believed to be deleterious and ameliorative. Results People with and without voice disorders reported pre-clear laryngeal sensation at a similar rate. Post-clear sensation was less likely to be completely or partially removed in people with voice disorders than in the non-voice disordered group. Hard throat clear and swallow with water were the most effective techniques at removing laryngeal sensation. Conclusions The findings provide initial evidence for some of the clinical practices common to treating patients with voice disorders and chronic clearing such as advocating for swallowing a sip of water as a replacement behavior instead of coughing or throat clearing. However, the findings raise questions about other practices such as associating irritating laryngeal sensation with a voice disorder. PMID:22717491

    The effects of hyperfractionation radiation therapy, such as the failure pattern and survival, on the treatment results in advanced stage head and neck cancer were studied. Between September 1990 and October 1998, 24 patients with advanced stage (III, IV) head and neck cancers, were treated using hyperfractionation radiation therapy in the Department at Radiation Oncology at the Keimyung University Dongsan Medical Center. The male to female ratio was 7 ; 1, and the age range from 38 to 71 years with the median of 56 years. With regard to the TNM stage, 11 patients were stage III and 13 were stage IV. The sites of primary cancer were the nasopharynx in six, the hypopharynx in 6, the larynx in five, the oropharynx in three, the maxillary sinus in three, and the oral cavity in one patient. The radiotherapy was delivered by 6 MV X-ray, with a fraction size of 1.2 Gy at two fractions a day, with at least 6 hours inter-fractional interval. The mean total radiation doses was 72 Gy, (ranging from 64.4 to 76.8 Gy). Fallow-up periods ranged between 3 and 136 months, with the median of 52 months. The overall survival rates at 3 and 5 years in all patients were 66.7% and 52.4%. The disease-free survival rates at 3 and 5 years (3YDFS, 5YDFS) in all patients Were 66.7% and 47.6%. The 3YDFS and 5YDFS in stage III patients were 81.8% and 63.6%, and those in stage IV patients were 53.8% and 32.3%. Ten patients were alive with no local nor distant failures at the time of analyses. Six patients (25%) died due to distant metastasis and 12.5% died due to local failure. Distant metastasis was the major cause of failure, but 2 patients died due to unknown failures and 3 of other diseases. The distant metastasis sites were the lung (3 patients), the bone (1 patient), and the liver (2 patients). One patient died of second esophageal cancer. There were no severe late complications, with the exception of 1 osteoradionecrosis of the mandible 58 months after treatment. Although this study was

    1995-01-01

    Purpose: To discuss both general and specific indications for radiation following surgery for patients with cancers of the head and neck. Patients with advanced cancers of the head and neck are often not suitable candidates for treatment with definitive radiation, and are treated with surgery. Frequently these patients fail by recurring in either the primary sites or in the necks. Adjuvant radiation is therefore often a critical component in the management of these patients. While radiation can be done either prior to or after surgery, most centers prefer the postoperative setting. This refresher course will review general concepts of postoperative irradiation for the patient with head and neck cancer and apply these concepts to specific situations. The course will begin with a broad review of the indications for postoperative irradiation as not all patients undergoing surgery for cancers of the head and neck require additional treatment. We will also review the concept of using postoperative radiation to allow for more conservative surgery with preservation of function. The second portion of the course will focus on general techniques of postoperative irradiation. We will review concepts of patient setup and treatment portal design and describe how specific techniques are practiced at MDACC. Controversial topics, including field matching, total dose and fractionation, and the timing of postoperative radiation will be discussed. The final section of the course will review the results of postoperative irradiation as applied to the head and neck in general as well as to specific subsites. In addition to results for the common scenarios of squamous cell carcinomas of the oral cavity, pharynx and larynx, we will review results of postoperative irradiation for skin cancers of the head and neck, paranasal sinuses, and salivary glands

    The recent development of helical (spiral) computed tomography allows collection of volumetric data to obtain high quality three-dimensional (3D) reconstructed images. The authors applied the 3D CT endoscopic imaging technique to asses normal and pathologic laryngeal structures. The latter included trauma, vocal fold atrophy, cancer of the larynx and recurrent nerve palsy. This technique was able to show normal laryngeal structures and characteristic findings of each pathology. The 3D CT endoscopic images can be rotated around any axis, allowing optimal depiction of pathologic lesion. The use of 3D CT endoscopic technique provides the display of the location and extent of pathology and affords accurate therapeutic planning. (author)

    Chemotherapy has been shown to be most effective when delivered concurrently with radiation for patients with untreated advanced-stage tumors. We conducted a concurrent chemoradiation protocol using systemic infusion of Cisplatin (CDDP) and 5-Fluorouracil (FU), followed by radical surgery. Thirty-six patients with advanced hypopharyngeal (n=28) or cervical esophageal cancer (n=8) received intravenous administration of CDDP (100 mg/m 2 ), followed by a 120-hour continuous infusion of 5-FU (1000 mg/m 2 /day), and concomitant radiotherapy (200 cGy/day x 20-35 fractions). One patient died of aspiration pneumonia. The rate of grade 3-4 hematological chemotoxicity was 27.8% (10/36). Pharyngo-laryngo-cervical esophagectomies were performed in 23 patients, one received partial resection of the hypopharynx, and one received radical neck dissection. Ten remaining patients refused radical surgery. In the resected specimens, 11 out of 24 (46%) were confirmed as complete response (CR). The median length of follow-up was 74.5 weeks. The projected 5-year survival was 39.7%. When the patients who had refused radical surgery for residual tumor were excluded, the 5-year survival rate rose up to 70.0% in the patients with hypopharyngeal cancer. Concurrent chemoradiotherapy can be safely and effectively applied. Preliminary pathological results indicate the possibility in improving the rate of organ preservation. (author)

  4. Differentiating laryngeal carcinomas from precursor lesions by diffusion-weighted magnetic resonance imaging at 3.0 T: a preliminary study.

    Directory of Open Access Journals (Sweden)

    De-Sheng Shang

    Full Text Available BACKGROUND: Diffusion-weighted magnetic resonance imaging (DWI has been introduced in head and neck cancers. Due to limitations in the performance of laryngeal DWI, including the complex anatomical structure of the larynx leading to susceptibility effects, the value of DWI in differentiating benign from malignant laryngeal lesions has largely been ignored. We assessed whether a threshold for the apparent diffusion coefficient (ADC was useful in differentiating preoperative laryngeal carcinomas from precursor lesions by turbo spin-echo (TSE DWI and 3.0-T magnetic resonance. METHODS: We evaluated DWI and the ADC value in 33 pathologically proven laryngeal carcinomas and 17 precancerous lesions. RESULTS: The sensitivity, specificity, and accuracy were 81.8%, 64.7%, 76.0% by laryngostroboscopy, respectively. The sensitivity, specificity, and accuracy of conventional magnetic resonance imaging were 90.9%, 76.5%, 86.0%, respectively. Qualitative DWI analysis produced sensitivity, specificity, and accuracy values of 100.0, 88.2, and 96.0%, respectively. The ADC values were lower for patients with laryngeal carcinoma (mean 1.195±0.32×10(-3 mm(2/s versus those with laryngeal precancerous lesions (mean 1.780±0.32×10(-3 mm(2/s; P<0.001. ROC analysis showed that the area under the curve was 0.956 and the optimum threshold for the ADC was 1.455×10(-3 mm(2/s, resulting in a sensitivity of 94.1%, a specificity of 90.9%, and an accuracy of 92.9%. CONCLUSIONS: Despite some limitations, including the small number of laryngeal carcinomas included, DWI may detect changes in tumor size and shape before they are visible by laryngostroboscopy. The ADC values were lower for patients with laryngeal carcinoma than for those with laryngeal precancerous lesions. The proposed cutoff for the ADC may help distinguish laryngeal carcinomas from laryngeal precancerous lesions.

    2003-01-01

    AIM: To evaluate results of pre-operative radiochemotherapy followed by surgery for 15 patients with locally advanced un-resectable rectal cancer.METHODS: 15 patients with advanced non-resectable rectal cancer were treated with pre-operative irriadiation of 40-46 Gy plus concomitant chemotherapy (5-FU+LV and 5′-DFuR) (RCS group). For comparison, 27 similar patients,treated by preoperative radiotherapy (40-50 Gy) plus surgery were served as control (RS group).RESULTS: No radiochemotherapy or radiotherapy was interrupted and then was delayed because of toxicities in both groups. The radical resectability rate was 73.3% in the RCS group and 37.0% (P=0.024) in RS group. Sphincter preservation rates were 26.6% and 3.7% respectively (P=0.028). Sphincter preservation rates of lower rectal cancer were 27.3 % and 0.0 % respectively (P=0.014). Response rates of RCS and RS groups were 46.7 % and 18.5 %(P=0.053). The tumor downstage rates were 8 (53.3%)and 9 (33.3%) in these groups (P=0.206). The 3-year overall survival rates were 66.7 % and 55.6% (P=0.485), and the disease free survival rates were 40.1% and 33.2%(P=0.663). The 3-year local recurrent rates were 26.7%and 48.1% (P=0.174). No obvious late effects were found in either groups.CONCLUSION: High resectability is possible following preoperative radiochemotherapy and can have more sphincters preserved. It is important to improve the quality of the patients′ life even without increasing the survival or local control rates. Preoperative radiotherapy with concomitant full course chemotherapy (5-Fu+LV and 5′-DFuR) is effective and safe.

    To assess the efficacy of the use of accelerated hyperfractionated radiotherapy (AHRT) for locally advanced uterine cervix cancers. Between May 2000 and September 2002, 179 patients were identified with FIGO stage IIB, IIIB, and IVA cancers. Of the 179 patients, 45 patients were treated with AHRT (AHRT group) and 134 patients were treated with conventional radiotherapy (CRT group), respectively. Patients undergoing the AHRT regimen received a dose of 30 Gy in 20 fractions (1.5 Gyx2 fractions/day) to the whole pelvis. Subsequently, with a midline block, we administered a parametrial boost with a dose of 20 Gy using 2 Gy fractions. Patients also received two courses of low-dose-rate brachytherapy, up to a total dose of 85∼90 Gy to point A. In the CRT group of patients, the total dose to point A was 85∼90 Gy. The overall treatment duration was a median of 37 and 66 days for patients that received AHRT and CRT, respectively. Statistical analysis was calculated by use of the Kaplan-Meier method, the log-rank test, and Chi-squared test. For patients that received cisplatin-based concurrent chemotherapy and radiotherapy, the local control rate at 5 years was 100% and 79.2% for the AHRT and CRT group of patients, respectively (p=0.028). The 5-year survival rate for patients with a stage IIB bulky tumor was 82.6% and 62.1% for the AHRT group and CRT group, respectively (p=0.040). There was no statistically significant difference for severe late toxicity between the two groups (p=0.561). In this study, we observed that treatment with AHRT with concurrent chemotherapy allows a significant advantage of local control and survival for locally advanced uterine cervix cancers

    Full Text Available Serial serum Carcinoembryonic antigen (CEA levels were measured in 150 individuals (50 patients with breast cancer, 50 benign breast diseases and 50 other controls. These levels were correlated with clinicopathological parameters and follow-up information. Serum CEA levels were independent of the primary tumor status, their histology, lymphoreticular response and the patients′ characteristics as well as the age, sex and the menstrual status. However, the nodal status, number of involved nodes and the grade of the tumors had significant influence on the level of serum CEA. Breast cancer patients especially those with metastasis had significantly higher serum CEA levels as compared to the controls and those with localised disease, irrespective of the site of metastasis. These levels were lowered appreciably by the disease regression and were raised or stable during the disease progression. Receiver operating characteristic (ROC curve showed metastasis to be more frequent in patients with pretreatment serum CEA levels above 25 ng/ml and persistent post treatment CEA levels above 15 ng/ml. Serum CEA level was found to be a valuable prognostic indicator for advanced breast cancer and serial serum CEA levels provided an average lead time of about 3.9 months before the clinical appearance of metastasis.

    We performed a pilot study to evaluate the safety and tolerability of bendamustine in patients with advanced hilar bile duct cancer and impaired liver function. Six patients with histologically proven, unresectable adenocarcinoma of the hilar bile duct were treated with bendamustine 140 mg/m intravenously on day 1 of the first cycle and with bendamustine 100 mg/m on days 1 and 2 of the second to fourth cycle. Treatment cycles were repeated every 21 days. Primary endpoint was the safety and tolerability of the treatment; secondary endpoints were response rate, time to progression and overall survival. Transient lymphopenia grade 3 occurred in all six patients. No other grade 3 or 4 toxicities were present. The most common nonhematologic toxicity was mouth dryness grade 2 in six patients. Three patients had stable disease. No partial or complete responses were observed. Median time to progression was 3.3 months; median overall survival was 6 months. Our study demonstrates that bendamustine can be safely administered in patients with hilar bile duct cancer and impaired liver function. A potential role of bendamustine in combination therapies for bile duct cancer will be a subject of further trials.

    With the newly-developed techniques of SEM cinematography, surface ultrastructures of the human normal and pathological laryngeal mucosa were demonstrated. The high specialization of the laryngeal mucosa with its marked regional differences stresses the fact that even the squamous epithelium and nonciliated epithelium may play a role of utmost importance. All specimens were obtained after laryngectomy from 10 patients affected by laryngeal cancer which had been treated with or without preoperative irradiation of Lineac in total doses of 3,500-4,500 rad. Special attention was paid to the occurrence of microvilli and microplicae in the normal and pathological mucosa of the larynx, and their morphological and physiological significances were discussed briefly.

    Pretreatment tables for the prediction of pathologic stage have been published and validated for localized prostate cancer (PCa). No such tables are available for locally advanced (cT3a) PCa. To construct tables predicting pathologic outcome after radical prostatectomy (RP) for patients with cT3a PCa with the aim to help guide treatment decisions in clinical practice. This was a multicenter retrospective cohort study including 759 consecutive patients with cT3a PCa treated with RP between 1987 and 2010. Retropubic RP and pelvic lymphadenectomy. Patients were divided into pretreatment prostate-specific antigen (PSA) and biopsy Gleason score (GS) subgroups. These parameters were used to construct tables predicting pathologic outcome and the presence of positive lymph nodes (LNs) after RP for cT3a PCa using ordinal logistic regression. In the model predicting pathologic outcome, the main effects of biopsy GS and pretreatment PSA were significant. A higher GS and/or higher PSA level was associated with a more unfavorable pathologic outcome. The validation procedure, using a repeated split-sample method, showed good predictive ability. Regression analysis also showed an increasing probability of positive LNs with increasing PSA levels and/or higher GS. Limitations of the study are the retrospective design and the long study period. These novel tables predict pathologic stage after RP for patients with cT3a PCa based on pretreatment PSA level and biopsy GS. They can be used to guide decision making in men with locally advanced PCa. Our study might provide physicians with a useful tool to predict pathologic stage in locally advanced prostate cancer that might help select patients who may need multimodal treatment.

    Full Text Available Xiaowen Zhang,1 Nan Wu2 1Medical Research Center, Shengjing Hospital of China Medical University, Shenyang, China; 2The Core Laboratory for Public Health Science and Practice, The First Affiliated Hospital of China Medical University, Shenyang, China Background: Rho-kinase signal pathway is a new target for cancer therapy. Fasudil, a selective Rho-kinase inhibitor, is found to exert antitumor effects on several types of cancer, but whether fasudil has antitumor effects on laryngeal carcinoma is still unknown. The aim of this study was to determine the effects of fasudil on laryngeal carcinoma and explore the underlying molecular mechanisms in this process. Methods: After treatment with fasudil, changes in biological behaviors, including the growth, proliferation, clone formation, apoptosis, and migration of human laryngeal carcinoma cells (Hep-2 cells were observed. The influences on apoptotic protease activity factor-1 (APAF-1-mediated apoptosis pathway and the activities of matrix metalloproteinases (MMP-2 and MMP-9 were measured by Western blotting and gelatin zymography assay. Results: Half-maximal inhibitory concentration of fasudil to Hep-2 cells was ~3.40×103 µM (95% CI: 2.53–4.66×103 µM. Moreover, fasudil treatment significantly decreased the ability of growth, proliferation, clone formation, and migration of Hep-2 cells, while remarkably increased the apoptosis rate. Furthermore, the expressions of APAF-1, caspase-9, and caspase-3 significantly increased in fasudil treatment group. Meanwhile, fasudil led to a remarkable decrease in the expressions and activities of MMP-2 and MMP-9. Conclusion: Our findings first demonstrate that fasudil not only inhibits the proliferation of laryngeal carcinoma cells through activating APAF-1-mediated apoptosis pathway, but also prevents migration by inhibiting the activities of MMP-2 and MMP-9. Therefore, fasudil is an attractive antitumor drug candidate for the treatment of laryngeal carcinoma

    Dry mouth (xerostomia) is one of the commonest symptoms in cancer patients and can adversely affect quality of life. The aim of this review was to determine the effectiveness of pharmacological and non-pharmacological interventions in treating xerostomia in adult advanced cancer patients. The literature search was performed in February 2014 using databases including EMBASE, MEDLINE, CINAHL, BNI and Cochrane library. The search was carried out using standard MeSH terms and was limited to adult population and English language. Studies investigating xerostomia secondary to head and neck cancer treatment and autoimmune disease were excluded. Titles and abstracts were screened and reviewed for eligibility. Only studies involving primary research were included in the analysis. Six studies met the eligibility criteria for review: three randomized controlled trials and three prospective studies. The quality assessment and reporting was performed using PRISMA, Jadad and STROBE. These studies compared acupuncture, pilocarpine, Saliva Orthana and chewing gum with each other or with placebo. All interventions were considered effective in treating xerostomia. However, effectiveness versus placebo could not be demonstrated for Saliva Orthana. Meta-analysis could not be performed due to heterogeneity of the study type and intervention. Limited published data exists reporting the effectiveness of measures in the treatment of xerostomia in cancer patients. Based on primary research of low quality, firm conclusions cannot be drawn. However, pilocarpine, artificial saliva, chewing gum and acupuncture can be tried based on the available data. This highlights the explicit need to improve our evidence base. Properly constructed randomized controlled trials demonstrating effectiveness of pharmacological and non-pharmacological interventions for dry mouth are required.

  18. The matrix metalloproteinase in larynx cancer

    Full Text Available One of the most common carcinoma occurring in the head and neck is laryngeal cancer. Despite the rapid scientific advances in medicine the prognosis for patients with such type of disease is not satisfying. In the last few years matrix metalloproteinases ‑ MMPs and their tissue inhibitors – TIMPs, mostly MMP‑2 and MMP‑9, arouses a great interest, especially in the process of carcinogenesis. It seems that their impact in the formation and development of laryngeal cancer is significant. MMPs a group of zinc‑ and calcium‑ dependent endopeptidases play crucial role extracellular matrix collagen degradation. That are enzymes, that degrade and the basement membrane by facilitating tumor growth, cell migration and tumor invasion. They are implicated in metastasis and angiogenesis potentiate within the tumor. Clear tendency was observed towards the higher MMPs and TIMPs expression in larynx cancer than in the stroma. Recent studies show correlations between increased MMP‑2 gene expression in the tumor tissue and clinical status, histopathological grading and metastases occurrence. The similar MMP2 over expression dependence were found on tumor recurrence and survival. Many authors pointed out, significant higher MMP‑2 expression as a potential marker of tumor invasiveness and worse prognosis in patients with larynx cancer. However, association of MMP 9 gene expression with laryngeal cancer clinicopathological features and survival of patients are ambiguous. Although, numerous researches show that this relationship does exists. Similar correlations could be found in TIMPs, but further studies are necessary because of small amount of literature.

    Our survey assessed the use of advanced radiotherapy technologies at the designated cancer care hospitals in Japan, and we identified several issues to be addressed. We collected the data of 397 designated cancer care hospitals, including information on staffing in the department of radiation oncology (e.g. radiation oncologists, medical physicists and radiation therapists), the number of linear accelerators and the implementation of advanced radiotherapy technologies from the Center for Cancer Control and Information Services of the National Cancer Center, Japan. Only 53% prefectural designated cancer care hospitals and 16% regional designated cancer care hospitals have implemented intensity-modulated radiotherapy for head and neck cancers, and 62% prefectural designated cancer care hospitals and 23% regional designated cancer care hospitals use intensity-modulated radiotherapy for prostate cancer. Seventy-four percent prefectural designated cancer care hospitals and 40% regional designated cancer care hospitals employ stereotactic body radiotherapy for lung cancer. Our multivariate analysis of prefectural designated cancer care hospitals which satisfy the institute's qualifications for advanced technologies revealed the number of radiation oncologists (P=0.01) and that of radiation therapists (P=0.003) were significantly correlated with the implementation of intensity-modulated radiotherapy for prostate cancer, and the number of radiation oncologists (P=0.02) was correlated with the implementation of stereotactic body radiotherapy. There was a trend to correlate the number of medical physicists with the implementation of stereotactic body radiotherapy (P=0.07). Only 175 (51%) regional designated cancer care hospitals satisfy the institute's qualification of stereotactic body radiotherapy and 76 (22%) satisfy that of intensity-modulated radiotherapy. Seventeen percent prefectural designated cancer care hospitals and 13% regional designated cancer care hospitals

    Advance directives are a sensitive issue among traditional Chinese people, who usually refrain from mentioning this topic until it is imperative. Medical decisions for cancer patients are made by their families, and these decisions might violate patients' personal will. This study aimed to examine the acceptance of advance directives among Chinese cancer patients and their families and patient participation in this procedure and, finally, to analyze the moral risk involved. While 246 patients and their family members refused official discussion of an advance directive, the remaining 166 patients and their families accepted the concept of an advance directive and signed a document agreeing to give up invasive treatment when the anti-cancer treatment was terminated. Of these, only 24 patients participated in the decision making. For 101 patients, anti-cancer therapy was ended prematurely with as many as 37 patients not told about their potential loss of health interests. Participants were 412 adult cancer patients from 9 leading hospitals across China. An advance directive was introduced to the main decision makers for each patient; if they wished to sign it, the advance directive would be systematically discussed. A questionnaire was given to the oncologists in charge of each patient to evaluate the interaction between families and patients, patients' awareness of their disease, and participation in an advance directive. Advance directives were not widely accepted among Chinese cancer patients unless anti-cancer therapy was terminated. Most cancer patients were excluded from the discussion of an advance directive.

    2017-03-01

    Full Text Available BACKGROUND Malignancies of larynx are an increasing global burden with a distribution of approximately 2-5% of all malignancies with an incidence of 3.6/1,00,000 for men and 1.3/1,00,000 for women with a male-to-female ratio of 4:1. Smoking and alcohol are major established risk factors. More than 90-95% of all malignancies are squamous cell type. Three main subsite of laryngeal malignancies are glottis, supraglottis and subglottis. Improved surgical techniques and advanced chemoradiotherapy has increased the overall 5 year survival rate. The above study is statistical analysis of laryngeal malignancies at our institution for a period of one year and analysis of pattern of distribution, aetiology, sites and subsites and causes for recurrence. MATERIALS AND METHODS Based on the statistical data available in the institution for the period of one year from January 2016-December 2016, all laryngeal malignancies were analysed with respect to demographic pattern, age, gender, site, subsite, aetiology, staging, treatment received and probable cause for failure of treatment. Patients were followed up for 12 months period during the study. RESULTS Total number of cases studied are 27 (twenty seven. Male cases are 23 and female cases are 4, male-to-female ratio is 5.7:1, most common age is above 60 years, most common site is supraglottis, most common type is moderately-differentiated squamous cell carcinoma, most common cause for relapse or recurrence is advanced stage of disease and poor differentiation. CONCLUSION The commonest age occurrence at the end of the study is above 60 years and male-to-female ratio is 5.7:1, which is slightly above the international standards. Most common site is supraglottis and not glottis. The relapse and recurrences are higher compared to the international standards.

    Targeted therapies have improved the survival of patients with advanced colorectal cancer (CRC). However, further improvements in patient outcomes may be gained by the development of predictive biomarkers in order to select individuals who are most likely to benefit from treatment, thus personalizing treatment. Using the epidermal growth-factor receptor (EGFR) pathway, we discuss the existing and potential predictive biomarkers in clinical development for use with EGFR-targeted agents in metastatic CRC. The data and technological issues surrounding such biomarkers as expression of EGFR or its family members or ligands, KRAS-, NRAS-, and BRAF-mutation status, PI3K/PTEN expression, and imaging and clinical biomarkers, such as rash and hypomagnesemia, are summarized. Although the discovery of KRAS mutations has improved patient selection for EGFR-targeted treatments, further biomarkers are required, especially for those patients who exhibit KRAS mutations rather than the wild-type gene

    The aim of this study was to investigate oral yeast carriage amongst patients with advanced cancer. Oral rinse samples were obtained from 120 subjects. Yeasts were isolated using Sabouraud's dextrose agar and CHROMagar Candida, and were identified using a combination of the API 20 C AUX yeast identification system, species-specific PCR and 26S rDNA gene sequencing. Oral yeast carriage was present in 66% of subjects. The frequency of isolation of individual species was: Candida albicans, 46%; Candida glabrata, 18%; Candida dubliniensis, 5%; others, yeast carriage was associated with denture wearing (P = 0.006), and low stimulated whole salivary flow rate (P = 0.009). Identification of these risk factors offers new strategies for the prevention of oral candidosis in this group of patients.

    In the past 5 years, quality-of-life (QOL) assessment measures such as the McGill, McMaster, Global Visual Analogue Scale, Assessment of QOL at the End of Life, Life Evaluation Questionnaire, and Hospice QOL Index have been devised specifically for patients with advanced cancer. The developers of these instruments have tried to respond to the changing needs of this specific population, taking into account characteristics including poor performance status, difficulty with longitudinal study, rapidly deteriorating physical condition, and change in relevant issues. Emphasis has been placed on patient report, ease and speed of completion, and the existential domain or meaning of life. Novel techniques in QOL measurement have also been adapted for palliative care, such as judgment analysis in the Schedule for the Evaluation of Individual Quality of Life. It is generally agreed that a single tool will not cover all QOL assessment needs.

    Background: Loss of phosphatase and tensin homologue deleted in chromosome 10 (PTEN) function in advanced colorectal cancer (CRC) may represent one of the resistance mechanisms to cetuximab by interfering with the epidermal growth factor receptor signal transduction pathway. Methods: PTEN expression tested by indirect immunofluorescence was evaluated both on primary (n=43) and on metastatic (n=24) sites in CRC patients treated with cetuximab. Results: The loss of PTEN expression tested on metastatic sites was negatively associated with response (100% progressive disease (PD) in PTEN-negative cases vs 30% PD in PTEN-positive cases; P<0.05), PFS (0.8 vs 8.2 months; P<0.001) and OS (2.9 vs 14.2 months; P<0.001). Conclusion: A potential role of PTEN in the anti-tumour activity of cetuximab could be hypothesised. PMID:19953097

    The results of two studies looking at the place of neo-adjuvant chemotherapy in the treatment of locally advanced cervical cancer being treated with radiotherapy are presented. Between August 1990 and January 1992, 184 patients with squamous cell carcinoma of the cervix, FIGO stage II B IVA were randomised (study 1) to receive either two cycles of bleomycin, ifosfamide-mesna and cisplatin (BIP) chemotherapy (CT) followed by radiotherapy (RT). Three patients died of CT toxicity - two in study 1 and one in study 2. Cystitis, proctitis and local skin reaction after RT occurred equally in the two groups in both the studies. The neo-adjuvant chemotherapy prior to radiotherapy demonstrated a high response rate, but this did not translate into improved overall survival compared to those patients receiving radiotherapy alone

    A total of 83 patients with locally advanced bladder cancer (T1, n=5; T2, n=28; T3a, n=21; T3b, n=21; T4, n=8) were treated with intra-arterial (i.a.) cisplatin and adriamycin (or epirubicin) chemotherapy. In 51 of the 83 cases, we combined this treatment with radiotherapy. The pathological complete response (CR) rate was 68% for all patients, 84% for i.a. chemotherapy combined with radiotherapy and only 41% for i.a. chemotherapy. The 5-year survival rate was 57% for all patients, 71% for i.a. chemotherapy combined with radiotherapy and only 44% for i.a. chemotherapy. The 5-year survival as a function of the clinical stage was 82% for T1+T2, 66% for T3a, 28% for T3b, 25% for T4 (T1+T2 vs. T3b: p<0.001, T1+T2 vs. T4: p<0.0001, T3a vs. T3b: p<0.0263, T3a vs. T4: p<0.0214, T3b vs. T4: p<0.029). In 46% of all patients, we succeeded in preserving the bladder; especially noteworthy, is that in 65% of the patients undergoing i.a. chemotherapy combined with radiotherapy, we succeeded in preserving the bladder. These results demonstrate that i.a. chemotherapy combined with radiotherapy is a useful method for locally advanced bladder cancer which may make preservation of the bladder function feasible.

    Endoscopy is essential for the diagnosis and treatment of cancers derived from the larynx. However, a laryngoscope with conventional white light (CWL) has technical limitations in detecting small or superficial lesions on the mucosa. Narrow band imaging especially combined with magnifying endoscopy (ME) is useful for the detection of superficial squamous cell carcinoma (SCC) within the oropharynx, hypopharynx, and oral cavity. A total of 3675 patients who have come to the outpatient clinic and complained of inspiratory stridor, dyspnea, phonation problems or foreign body sensation, were enrolled in this study. We describe the glottic conditions of the patients. All 3675 patients underwent laryngoscopy equipped with conventional white light (CWL) and NBI system. 1149 patients received a biopsy process. And 1153 lesions were classified into different groups according to their histopathological results. Among all the 1149 patients, 346 patients (312 males, 34 females; mean age 62.2±10.5 years) were suspected of having a total of 347 precancerous or cancerous (T1 or T2 without lymphnode involvement) lesions of the larynx under the CWL. Thus, we expected to attain a complete vision of what laryngeal lesions look like under the NBI view of a laryngoscope. The aim was to develop a complete description list of each laryngeal conditions (e.g. polyps, papilloma, leukoplakia, etc.), which can serve as a criteria for further laryngoscopic examinations and diagnosis.

    The large body of empirical research suggesting that patients' spiritual and existential experiences influence the disease process has raised the need for health care professionals to understand the complexity of patients' spiritual pain and distress. The current study explores the multidimensional nature of spiritual pain, in patients with end-stage cancer, in relation to physical pain, symptom severity, and emotional distress. The study combines a quantitative evaluation of participants' intensity of spiritual pain, physical pain, depression, and intensity of illness, with a qualitative focus on the nature of patients' spiritual pain and the kinds of interventions patients believed would ameliorate their spiritual pain. Fifty-seven patients with advanced stage cancer in a palliative care hospital were interviewed by chaplains. Overall, 96% of the patients reported experiencing spiritual pain, but they expressed it in different ways: (1) as an intrapsychic conflict, (2) as interpersonal loss or conflict, or (3) in relation to the divine. Intensity of spiritual pain was correlated with depression (r = 0.43, p spiritual pain did not vary by age, gender, disease course or religious affiliation. Given both the universality of spiritual pain and the multifaceted nature of pain, we propose that when patients report the experience of pain, more consideration be given to the complexity of the phenomena and that spiritual pain be considered a contributing factor. The authors maintain that spiritual pain left unaddressed both impedes recovery and contributes to the overall suffering of the patient.

    Background. Local progression of advanced gastric cancer often manifests as bleeding, dysphagia/obstruction, or pain. We evaluated the magnitude and durability of palliation with radiotherapy (RT). Material and methods. From 1996 to 2004, 37 gastric cancer patients were treated with palliative RT (median dose 35Gy in 14 fractions). Nearly two-thirds of all patients received concurrent chemoradiation therapy (CRT). Index pre-treatment symptoms were gastric bleeding, dysphagia/obstruction, and pain in 54%, 43%, and 19% of patients, respectively. Results. The rates of control for bleeding, dysphagia/obstruction, and pain were 70% (14/20), 81% (13/16), and 86% (6/7), respectively. These symptoms were controlled without additional interventions for a median of 70%, 81%, and 49% of the patient's remaining life, respectively. Patients receiving CRT had a trend towards better median overall survival than those receiving RT alone (6.7 vs. 2.4 months, p=0.08). Lower (<41 Gy) biologically effective dose (BED, assuming an alpha/beta ratio of 10 for early responding tissues) predicted for poorer local control (6-month local control 70% vs. 100%, p=0.05) while T4 tumors had a trend towards inferior local control (6-month LC 56% vs. 100%, p=0.06). Discussion. Palliative RT controls symptoms for most of the remaining life in the majority of gastric cancer patients. The role of a higher dose of RT (BED >= 41 Gy), especially in patients with T4 tumors, remains to be established. In order to accurately define the role for radiotherapy in palliation of these symptoms, prospective randomized studies need to be conducted.

    To determine the pathologic effectiveness of preoperative chemoradiotherapy (CRT) in patients with advanced rectal carcinoma, we reviewed clinical records of 76 patients who received preoperative pelvic radiation +/- chemotherapy. Since 2 patients refused operation and 2 died before surgery, 72 patients underwent operation with a mean delay of 19.9 days after completion of irradiation. Pathologic tumor regression grade (Grade 0-3) was determined by the amount of viable tumor versus necrosis and fibrosis. Grade 0, 1a, 1b, 2, and 3 (pCR) were observed in 0%, 25.0%, 38.9%, 27.8% and 2.8% of patients, respectively. The pathologic response (PR) rate was 75.0% when PR was defined as greater than grade 1b (tumor regression more than 1/3). Downstaging was observed in 35.8% of patients, in which 5-year overall survival was significantly better than in patients without downstaging (90.0% vs. 50.1%, p<0.05). No correlation could be observed between PR and downstaging. CRT is a useful tool with a high PR rate in patients with advanced rectal cancer. More accurate and careful clinical staging is important to select adequate candidates for CRT. Multi-institutional clinical trials as well as standardizing the surgical procedure including lymph node (LN) dissection are required to validate the advantages of CRT for Japanese patients.

    We performed a retrospective non-randomized clinical study of locally advanced rectal cancer, to evaluate the anal sphincter preservation rates, down staging rates and survival rates of preoperative chemoradiotherapy. From January 2002 to December 2005, patients with pathologically confirmed rectal cancer with clinical stage T2 or higher, or patients with lymph node metastasis were enrolled in this study. A preoperative staging work-up was conducted in 36 patients. All patients were treated with preoperative chemoradiotherapy, and curative resection was performed for 26 patients at Hallym University Sacred Heart Hospital. Radiotherapy treatment planning was conducted with the use of planning CT for all patients. A total dose of 45.0 {approx} 52.2 Gy conventionally fractionated three-dimensional radiotherapy was delivered to the whole pelvis. Chemotherapy was given at the first and fifth week of radiation therapy with continuous infusion i.v. 5-FU (Fluorouracil) and LV (Leucovorine). Surgical resection was performed 2 to 4 weeks after the completion of the chemoradiotherapy regimen. The complete resection rate with negative resection margin was 100% (26/26). However, a pathologically complete response was not seen after curative resection. Surgery was done by LAR (low anterior resection) in 23 patients and APR (abdomino-perineal resection) in 3 patients. The sphincter preservation rate was 88.5% (23/26), down staging of the tumor occurred in 12 patients (46.2%) and down-sizing of the tumor occurred in 19 patients (73%). Local recurrence after surgical resection developed in 1 patient, and distant metastasis developed in 3 patients. The local recurrence free survival rate, distant metastasis free survival rate, and progression free survival rate were 96.7%, 87% and 83.1%, respectively. Treatment related toxicity was minimal except for one grade 3, one grade 4 anemia, one grade 3 leukopenia, and one grade 3 ileus. Preoperative concurrent chemoradiotherapy for locally

    Secondary pneumothorax with advanced lung cancer is an intractable and serious pathosis, which directly aggravates patients' Quality of Life (QOL) and prognosis. We first select the intrapleural administration of fibrin glue for secondary pneumothorax with advanced lung cancer. From April 2009 to May 2012, we encountered 5 patients who developed secondary pneumothorax during treatment for advanced lung cancer. Their average age was 60.8 years old, and 4 of them had squamous cell carcinoma, 1 had adenocarcinoma, and all had unresectable advanced lung cancer. In 4 of them, the point of air leakage could be detected by pleurography, and leakage could be stopped by the intrapleural administration of fibrin glue. All of them could receive chemotherapy or radiotherapy after treatment for secondary pneumothorax. The intrapleural administration of fibrin glue may be an effective and valid treatment for intractable secondary pneumothorax with advanced lung cancer. (author)

    Despite early detection of breast cancer and the progress of treatment modalities, metastasis-specific symptoms continue to impact women's functional status and daily living. The aim of this study was to explore the experience of altered functional status and social roles of women with advanced breast cancer. Using qualitative descriptive methodology, semi-structured interviews were conducted with 10 women diagnosed with advanced breast cancer and altered functional status attending a tertiary care cancer centre. Results illustrated the adaptive experience of women living with their illness as they reshaped their social roles to fit with their altered functional status and advanced disease. These findings highlight the opportunity for supportive care nursing interventions to facilitate the behavioural and cognitive transitions that are experienced by women with advanced breast cancer and altered functional status. These results may have implications for women with other advanced chronic diseases, though more research is required.

    Objective: To investigate the expressions of Fra -1 and HMGA 1 in laryngeal squamous cell carcinoma and their correlation . Methods: Immunohistochemistry and reverse transcription-polymer chain reaction (RT-PCR) were used to detect the expressions of HMGA 1 and Fra -1 in laryngeal squamous carcinoma tissues in 47 cases and para - carcinoma tissues in 21 cases ( the First Hospital of Shijiazhuang ). The relationship between the gene expressions in carcinoma tissues and clinopathological parameters such as pathological grade, clinical stage, lymph metastasis, age and anatomic site and the relevance of the two gene expressions were analyzed . SPSS 13.0 software was used to analyze the data . Results: The positive expression rates of Fra-1 and HMGA1 proteins in laryngeal squamous cancer tissue were 48.9% and 53.2%, which were respectively higher than the rates of 19.0% for Fra-1 (χ(2)=5.416, P 0.05). The expression of HMGA 1 gene was correlation with pathological grade, clinical stage, lymph metastasis and age (t values were -1.112, -1.065, -1.009 and -1.066, all P0.05). The expressions of Fra -1 and HMGA 1 gene were positively correlation (r=0.672, P<0.05). Conclusions: In laryngeal squamous cancer, Fra -1 and HMGA 1 are excessive expression, with a positive correlation between the expressions of both genes .

    Full Text Available An 81-year-old male with early-stage laryngeal carcinoma had been treated with 60 Gy curative radiotherapy. He complained of a sore throat, foul odor in the mouth, progressive dyspnea, and fever 2 months after the completion of radiotherapy. Direct laryngoscopy revealed narrowing of the glottis with diffuse ulcerative necrotic tissue. Biopsies at multiple sites and pathology revealed intense coagulation necrosis with complete denudation of covering epithelium without any malignancy. Since laryngeal radionecrosis was suspected, the patient received hyperbaric oxygen (HBO therapy 40 times for 1 hour of 100% O2 at 2 atm absolute pressure. His clinical symptoms gradually improved and repeated endolaryngeal biopsies were undertaken near the end of HBO therapy and again 6 months later. The patient's larynx healed completely with diffuse fibrosis and no malignant cells were found on pathology. Radionecrosis must be differentiated from cancer recurrence following curative radiotherapy for early laryngeal cancer. HBO therapy could be a useful treatment adjunct for laryngeal radionecrosis.

    A hypermutated subtype of advanced prostate cancer was recently described, but prevalence and mechanisms have not been well-characterized. Here we find that 12% (7 of 60) of advanced prostate cancers are hypermutated, and that all hypermutated cancers have mismatch repair gene mutations and microsatellite instability (MSI). Mutations are frequently complex MSH2 or MSH6 structural rearrangements rather than MLH1 epigenetic silencing. Our findings identify parallels and differences in the mechanisms of hypermutation in prostate cancer compared with other MSI-associated cancers.

    Gastric cancer is one of the leading causes of cancer-related deaths in both sexes worldwide, especially in Eastern Asia. This study aimed to estimate the economic burden of advanced gastric cancer (AGC) in Taiwan. The costs of AGC in 2013 were estimated using resource use data from a chart review study (n = 122 with AGC) and national statistics. Annual per-patient costs, where patients' follow-up periods were adjusted for, were estimated with 82 patients who had complete resource use data. The costs were composed of direct medical costs, direct non-medical costs (healthcare travel and caregiver costs), morbidity costs, and mortality costs. Relevant unit costs were retrieved mainly from literature and national statistics, and applied to the resource use data. A broad definition of morbidity and mortality costs was employed to value the productivity loss in patients with unpaid employment, economically inactive and unemployed as well as the life years after the age of retirement. Their narrow definitions were also used in sensitivity analyses, using age- and/or sex-specific employment rates. Forgone future earnings/productivity loss were discounted at 3%. Annual per-patient costs were projected to estimate the total costs of AGC at the national level with an estimated number of patients with AGC (N = 2611) in Taiwan in 2013. The mean age of the 82 patients was 59.3 (SD: 11.9) years, and 67.1% were male. Per-patient costs were US$26,431 for direct medical costs, US$4669 for direct non-medical costs, US$5758 for morbidity costs, and US$145,990 for mortality costs (per death). These per-patient costs were projected to incur total AGC costs of US$423 million at the national-level. Mortality costs accounted for 77.3% of the total costs, followed by direct medical costs (16.3%), morbidity costs (3.6%), and direct non-medical costs (2.9%). AGC was found to exert a significant economic burden in Taiwan, incurring US$423 million in 2013. This represents about 0.08% of

  20. Treatment of locally advanced/locally recurrent breast cancer and inflammatory breast cancer

    2000-01-01

    This paper summarizes the treatment of locally advanced breast cancer, inflammatory breast cancer, and locally recurrent breast cancer. A multidisciplinary approach considering subclinical distant metastases is needed to treat these types of breast cancer. Subclinical distant metastasis is observed in about 80% of case of locally advanced cancer, and treatment of subclinical distant metastases, e.g., by endocrinotherapy and chemotherapy, is therefore essential to improving the prognosis. The standard therapy for unresectable locally advanced breast cancer consists of induction chemotherapy with anthracyclines and local treatment with mastectomy or irradiation. Previous reports have stated that induction chemotherapy was effective in 60-80% of the primary lesions or lymph node metastasis, and the CR rates were in the 10-20% range. Combination therapy with induction chemotherapy clearly improved the outcome over local treatment alone. The usual irradiation dose is 50 to 60 Gy/5 to 7 weeks to the whole breast or the thoracic wall. Boost irradiation at a dose of 10 to 25 Gy is performed in unresectable cases. The boost irradiation dose to the lymph node area is usually 45 to 50 Gy/5 to 6 weeks in cases without gross lesions and 10 to 15 Gy in cases with gross lesions. Combination therapy consisting of conservative pectoral mastectomy and postoperative adjuvant chemo- endocrino-therapy (i.e., adjuvant therapy) has become the standard regimen for treating resectable locally advanced breast cancer, because it significantly improves the recurrence rate and survival rate compared to local treatment alone. Some clinical have studies indicated that neoadjuvant therapy (i.e., induction chemotherapy + surgery/radiation therapy) is comparable or superior to adjuvant therapy in terms of improving the prognosis. However, the efficacy and most appropriate method of breast-conserving therapy after induction chemotherapy are still unclear. More clinical trials are needed. It has been

    Full Text Available Background and Aim: Reflux laryngitis is extremely common among patients with voice disorder. Medical therapy approaches are not efficient enough. The main goal of this study is to assess the acoustic and laryngeal characteristics of patients with dysphonia before and after medical or voice therapy, and to evaluate the effectiveness of each.Methods: In this retrospective study, 16 reflux laryngitis patients were assessed. Five received complete voice therapy, tow ceased voice therapy and nine received medication. Perceptual voice evaluation was performed by a speech-language pathologist, the severity of voice problem was calculated, based on the affected acoustic and laryngeal characteristics pre- and post-treatment.Results: Post-treatment evaluation in patients who received complete voice therapy indicates 80 percent improvement in the severity of disorder and 100 percent improvement in the perceptual voice evaluation. After medical therapy, we observed that voice disorder and perceptual voice evaluation are improved 44 and 66 percent respectively. The improvement was statistically significant in both treatment approaches: complete voice therapy (P=0.039 and medical therapy (p=0.017.Conclusion: In patients with reflux laryngitis, most acoustic and laryngeal characteristics were normal and satisfying after the treatment. It can be concluded that the proficiency of voice therapy in improving the acoustic and laryngeal characteristics is comparable to medical therapy

    The standard therapy is not yet established for the unresectable advanced gallbladder cancer (AGC). Here described is the outcome of authors' therapeutic protocol for AGC during the time Jan., 1989-Dec., 2008. Subjects are 73 patients (M 32/F 41, average age 65 y) with AGC of Stage IV. One shot arterial infusion (AI) of EEP regimen (etoposide (VP16)/4'epiadriamycin (EPIR)/cisplatin (CDDP)) is conducted via hepatic artery proper or common at the first angiography and one week later, external radiation therapy (RT), with about 30-50 Gy/6 fractions (actually, 12-61.6 Gy). AI is weekly done with FP regimen (CDDP/5-fluorouracil (FU)) through the reservoir indwelled in the gastroduodenal artery for 6 months where a metal stent for the stegnosis of bile duct is used if necessary after RT, and in recent days, additionally with biweekly CDDP/gemcitabin (GEM) regimen depending on patient's state after FP. As a result, RT is conducted to 62 cases (RT alone 8 cases), AI, 64 (alone, 10), and RT+AI, 54. Response is found to be 49% (CR 7 cases and PR, 28). Survivals 1- and 3-year are 39 and 6%, respectively, and average survival time, 408 days. Survival rate in (RT+AI) is significantly superior to that in AI alone and in RT alone. Prognosis in patients with jaundice, hepatic or duodenal invasion is significantly inferior to those without the symptom, and in non-responded cases, to responded cases. Complications like hepatic abscess are seen in 4 cases at 6 months after treatment. Four actual case-reports are presented in details with their images. Combination of RT+AI is suggested to be of utility for AGC, of which multi-center trial is awaited with addition of newer anti-cancers developed recently. (K.T.)

  4. Concept and viability of androgen annihilation for advanced prostate cancer.

    2014-09-01

    There remains no standard of care for patients with a rising prostate-specific antigen level after radical prostatectomy or radiotherapy but who have no radiographic metastases, even though this is the second largest group of patients with prostate cancer (CaP) in the United States. Androgen deprivation therapy (ADT) may cure some men with advanced CaP based on single-institution series and a randomized clinical trial of immediate versus delayed ADT for men found to have pelvic lymph node metastasis at the time of radical prostatectomy. ADT may be more effective when initiated for minimal disease burden, which can be detected using PSA after radical prostatectomy or radiotherapy, and if more complete disruption of the androgen axis using newer agents decreases the chance that androgen-sensitive cells survive to adapt to a low-androgen environment. Androgens may be "annihilated" simultaneously using a luteinizing hormone-releasing hormone antagonist or agonist to inhibit testicular production of testosterone, a P45017A1 (CYP17A1) inhibitor to diminish metabolism of testosterone via the adrenal pathway and dihydrotestosterone (DHT) via the backdoor pathway, a 5α-reductase (SRD5A) inhibitor to diminish testosterone reduction to DHT and backdoor metabolism of progesterone substrates to DHT, and a newer antiandrogen to compete better with DHT for the androgen receptor ligand-binding domain. Early initiation of androgen annihilation for induction as part of planned intermittent ADT should be safe, may reduce tumor burden below a threshold that allows eradication by the immune system, and may cure many men who have failed definitive local therapy. © 2014 American Cancer Society.

    Understanding the complexity of cancer biology requires extensive information about the cancer proteome over the course of the disease. The recent advances in mass spectrometry-based proteomics technologies have led to the accumulation of an incredible amount of such proteomic information. This information allows us to identify protein signatures or protein biomarkers, which can be used to improve cancer diagnosis, prognosis and treatment. For example, mass spectrometry-based proteomics has been used in breast cancer research for over two decades to elucidate protein function. Breast cancer is a heterogeneous group of diseases with distinct molecular features that are reflected in tumour characteristics and clinical outcomes. Compared with all other subtypes of breast cancer, triple-negative breast cancer is perhaps the most distinct in nature and heterogeneity. In this review, we provide an introductory overview of the application of advanced proteomic technologies to triple-negative breast cancer research.

    We performed the retrospective analysis to find the outcome of external beam radiotherapy alone in advanced esophageal cancer patients. One hundred and six patients treated with external beam radiotherapy alone between July 1990 and December 1996 were analyzed retrospectively. We limited the site of the lesions to the thoracic esophagus and cell type to the squamous cell carcinoma. Follow-up was completed in 100 patients (94%) and ranged from 1 month to 92 months (median; 6 months). The median age was 62 years old and male to female ratio was 104:2. Fifty-three percent was the middle thorax lesion and curative radiotherapy was performed in 83%. Mean tumor dose delivered with curative aim was 58.6 Gy (55-70.8 Gy) and median duration of the radiation therapy was days. The median survival of all patients was 6 months and 1-year and 2-year overall survival rate was 27% and 12%, respectively. Improvement of dysphagia was obtained in most patients except for 7 patients who underwent feeding gastrostomy. The complete response rate immediately after radiation therapy was 32% (34/106). The median survival and 2-year survival rate of the complete responder was 14 months and 30% respectively, while those of the nonresponder was 4 months and 0% respectively (p=0.000). The median survival and 2-year survival rate of the patients who could tolerate regular diet was 9 months and 16% while those of the patients who could not tolerate regular diet was 3 months and 0%, respectively (p=0.004). The survival difference between the patients with 5 cm or less tumor length and those with more than 5 cm tumor length was marginally statistically significant (p=0.06). However, the survival difference according to the periesophageal invasion or mediastinal lymphadenopathy in the chest CT imaging study was not statistically significant in this study. In a multivariate analysis, the statistically significant covariates to the survival were complete response to radiotherapy, tumor, length, and

    To see the relationship between the response to chemotherapy and the final outcome of neoadjuvant chemotherapy and radiotherapy in patients with locally advanced hypopharyngeal cancer. A retrospective analysis was done for thirty-two patients with locally advanced hypopharyngeal cancer treated in the Seoul National University Hospital with neoadjuvant chemotherapy and radiotherapy from August 1979 to July 1997. The patients were treated with Co-60 teletherapy unit or 4MV or 6MV photon beam produced by linear accelerator. Daily fractionation was 1.75 to 2 Gy, delivered five times a week. Total dose ranged from 60.8 Gy to 73.8 Gy. Twenty-nine patients received continuous infusion of cisplatin and 5-FU. Other patients were treated with cisplatin combined with bleomycin or vinblastin. Twenty-four (75%) patients received all three prescribed cycles of chemotherapy delivered three weeks apart. Six patients received two cycles, and two patients received only one cycle. The overall 2-year and 5-year survival rates are 65.6% and 43.0, respectively. 5-year local control rate is 34%. Organ preservation for more than five years is achieved in 12 patients (38%). After neoadjuvant chemotherapy, 24 patients achieved more than partial remission (PR); the response rate was 75% (24/32). Five patients had complete remission (CR), 19 patients PR, and 8 patients no response (NR). Among the 19 patients who had PR to chemotherapy, 8 patients achieved CR after radiotherapy. Among the 8 non-responders to chemotherapy, 2 patients achieved CR, and 6 patients achieved PR after radiotherapy, There was no non-responder after radiotherapy. The overall survival rates were 60% for CR to chemotherapy group, 35.1 % for PR to chemotherapy group, and 50% for NR to chemotherapy group. respectively (p=0.93). There were significant difference in five-year overall survival rates between the patients with CR and PR after neoadjuvant chemotherapy and radiotherapy (73.3% vs. 14.7%, p< 0.01). The prognostic

We evaluated the efficacy and safety of a partially completed chemoradiation regimen prescribed for locally advanced carcinoma of the cervix. Methods: Medical records of 156 patients with locally advanced cervical cancer stage IIB–IVA who received chemoradiation with cisplatin (40 mg/m2 and 5-fluorouracil (500 mg/m2 from October 2006 to October 2008 were collected. The treatment protocol called for two cycles of chemotherapy. External beam radiation therapy was administered using a 10-MeV electron beam. Local control, disease free survival, overall survival, and toxicities were evaluated. Results: With a median follow-up of 37.5 months, 89 patients (57% completed the planned protocol. Sixty seven patients (43% completed fewer than two cycles. The 3-year local control rate was significantly better in the patient group that completed the prescribed plan (92.1% compared to 80.6%; P = 0.033. No statistical significance was observed between the groups that completed or did not complete the two cycle protocol with regard to disease free survival (80.9% and 73.2%, respectively; P = 0.250, overall survival (84.3% and 79.1%; P = 0.405, and progression survival (3.4% and 3.0%; P = 0.892. Differences in acute hematologic toxicity and subcutaneous toxicity were observed between the two groups. Conclusions: Completion of two cycles of 5-fluorouracil and cisplatin with radiotherapy was effective, safe, and responsible for better local control

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

    The anatomical characteristic of the pediatric larynx allows physicians to better understand the incidence of symptomatic and severe presentations of acute laryngitis, which are frequent pediatric emergencies. Subglottis laryngitis and epiglottitis must be distinguished from each other. These two diseases are absolutely different: the first one is essentially viral and usually moderate, even though acute respiratory distress can occur. The other (epiglottitis) is bacterial, essentially caused by Haemophilus influenza B (Hi-B), and can be life threatening. The anti Hi-B vaccine leads to a decrease of frequency but does not make them disappear. Moreover, even if a child has a history of the Hi-B vaccine, diagnosis of epiglottitis can not to be ruled out. Lastly, in case of acute laryngeal dyspnea in a child, one must think about a foreign body.

    Full Text Available This study describes preliminary laryngeal electromyography (LEMG data and botulinum toxin treatment in patients with dysphonia due to movement disorders. Twenty-five patients who had been clinically selected for botulinum toxin administration were examined, 19 with suspected laryngeal dystonia or spasmodic dysphonia (SD, 5 with vocal tremor, and 1 with Gilles de la Tourette syndrome (GTS. LEMG evaluations were performed before botulinum toxin administration using monopolar electrodes. Electromyography was consistent with dystonia in 14 patients and normal in 5, and differences in frequency suggesting essential tremor in 3 and Parkinson tremors in 2. The different LEMG patterns and significant improvement in our patients from botulinum toxin therapy has led us to perform laryngeal electromyography as a routine in UNICAMP movement disorders ambulatory.

  12. New developments in chemotherapy of advanced breast cancer.

    Anthracyclines and taxanes are the two most active classes of chemotherapy for the treatment of advanced breast cancer. Recent studies have investigated combination therapy including doxorubicin (Dox) and paclitaxel. The efficacy of this combination has been established in a phase III study conducted by ECOG, comparing Dox/paclitaxel versus Dox versus paclitaxel. The combination is superior to Dox or paclitaxel with respect to response rate and time to disease progression, indicating that the combination provides a new standard for the first line treatment of metastatic breast cancer [1]. Phase II studies using higher doses of Dox and using shorter infusions of paclitaxel have suggested the combination can be further optimized; Gianni reported a 94% objective response rate using Dox 60 mg/m2 followed by paclitaxel 175 mg/m2 given over three hours [2]. The more active regimens are associated with enhanced cardiotoxicity; this toxicity can be avoided, however, by limiting the exposure to doxorubicin. The newer regimens have now been moved into phase III studies. Future progress for this disease will depend on the introduction of new agents. Two novel drugs are currently being investigated in randomised phase III trials as potentiators of Dox and/or paclitaxel. One is a monoclonal antibody from Genentech (Herceptin, trastuzumab) directed at the HER-2/neu oncogene, which is overexpressed in > 25% of breast cancers [3]. Recent results indicate that Herceptin in combination with paclitaxel (or with a Dox plus cyclophosphamide regimen) induces a higher response rate (RR) and prolongs the time to disease progression when compared to chemotherapy alone. The second agent N,N-diethyl-2[4-(phenylmethyl)-phenoxy] ethanamine.HCl (DPPE, BMS-217380-01), when combined with Dox, was associated with a higher RR than previously observed with Dox alone [4]. A randomized trial of Dox versus Dox plus DPPE is ongoing. The possible mechanisms underlying chemo-potentiation by these agents

    The purpose of this pilot study was to investigate the palliative potential of home-based yoga sessions provided to women with advanced cancer. Personalised 45-minute yoga sessions were offered to three women with advanced cancer by an experienced yoga teacher. Each woman took part in a one-to-one interview after the completion of the yoga programme and was asked to describe her experiences of the programme's impact. The personalised nature of the yoga sessions resulted in similar positive physical and psychosocial effects comparable to those demonstrated in other studies with cancer patients. Participants described physical, mental, and emotional benefits as well as the alleviation of illness impacts. The enhancement of mind-body and body-spirit connections were also noted. Personalised home-based yoga programmes for people with advanced cancer may produce similar benefits, including palliation, as those institutionally-based programmes for people with non-advanced cancer.

    Uncontrolled pain, especially in patients with advanced cancer, affects quality of life negatively and causes negative physical and psychological conditions. The aim of this study was to explore the pain experiences of patients with advanced cancer and how they manage with pain, and to present a view of pain management approaches of nurses from the perspectives of the patients. This was a qualitative descriptive study of sixteen hospitalized patients with advanced cancer. Data were collected using semi-structured interviews with patients. Data were analysed by Colaizzi's phenomenological method. This study found that patients with advanced cancer who had pain experienced anxiety, helplessness, hopelessness and many restrictions in daily life as well as inability to manage with pain. Most of the patients with advanced cancer were not satisfied with their nursing care with regard to pain management. The themes that emerged were pain perception and experiences, effects of pain on daily life, pain management and management strategies and the patients' perspectives about nursing approaches to pain. This study demonstrated the difficulties of patients with advanced cancer who experienced pain in their daily lives, yet lack pain management strategies. Furthermore, nurses' caring approaches to patients with advanced cancer who experienced pain was found inadequate. Oncology nurses should provide educational interventions in order to enhance knowledge and skills about pain assessment and non-pharmacologic and pharmacologic strategies used in pain management.

    Pancreatic cancer is one of the most lethal cancers among all malignances, with a median overall survival of cancers harbor a variety of genetic alternations that render it difficult to treat even with targeted therapy. Recent studies revealed that pancreatic cancers are highly enriched with a cancer stem cell (CSC) population, which is resistant to chemotherapeutic drugs, and therefore escapes chemotherapy and promotes tumor recurrence. Cancer cell epithelial to mesenchymal transition (EMT) is highly associated with metastasis, generation of CSCs, and treatment resistance in pancreatic cancer. Reviewed here are the molecular biology of pancreatic cancer, the major signaling pathways regulating pancreatic cancer EMT and CSCs, and the advancement in current clinical and experimental treatments for pancreatic cancer.

    Acyl ghrelin is an orexigenic peptide. Active ghrelin ratio, the ratio of acyl ghrelin to total ghrelin, has an important role in physiological functions and gastrointestinal symptoms. However, low active ghrelin ratio-related characteristics, gastrointestinal symptoms, and chemotherapy-induced gastrointestinal toxicity in patients with advanced pancreatic cancer have not been previously evaluated. The goal of this study was to identify low active ghrelin ratio-related factors in treatment-naïve advanced pancreatic cancer patients. Patients with treatment-naïve advanced pancreatic cancer were eligible for inclusion in this study. Active ghrelin ratio and clinical parameters of patients were prospectively recorded. Factors correlated with low active ghrelin ratio and survival were analyzed. In total, 92 patients were analyzed. Low active ghrelin ratio-related factors were advanced age (P advanced pancreatic cancer.

    The last 20 years have seen significant improvements in the analytical capabilities of biological mass spectrometry (MS). Studies using advanced MS have resulted in new insights into cell biology and the etiology of diseases as well as its use in clinical applications. This review discusses recent developments in MS-based technologies and their cancer-related applications with a focus on proteomics. It also discusses the issues around translating the research findings to the clinic and provides an outline of where the field is moving. Expert commentary: Proteomics has been problematic to adapt for the clinical setting. However, MS-based techniques continue to demonstrate potential in novel clinical uses beyond classical cancer proteomics.

    Neurofibromatosis (NF) is a genetically inherited, autosomal dominant disease, characterized by multiple cafe au lait spots, cutaneous neurofibromas and "Lisch nodules." Neurofibromatosis can develop from a neural source at any age. However, neurofibroma of the larynx is extremely rare and is usually manifested by obstructive airway symptoms. We encountered a 5-year-old child presenting with stridor and dyspnea, who had a diagnosis of laryngeal plexiform neurofibroma. The purpose of our report is the consideration of laryngeal NF in the differential diagnosis of dyspnea in infants and children.

    Laryngeal cartilaginous framework tumors are very rare. Chondroma and chondrosarcoma are the most common types of these tumors. A 27-year-old man with a history of intubation presented with exercise-induced dyspnea. A computed tomography scan of larynx showed a rounded and circumscribed mass without infiltration of the adjacent structures which obstructs 75% of airway. Histopathological investigation of the mass revealed the chondroma of the larynx. The patients' history of intubation trauma with the subsequent progressive onset of clinical symptoms demonstrates the relationship between these 2 entities. Clinicians should consider laryngeal chondroma in the differential diagnosis of dyspnea after endotracheal intubation.

    Full Text Available A child suspected of exercise-induced laryngeal obstruction and asthma is examined by laryngoscopy and respiratory resistance (Rrs after exercise challenge. Immediately at exercise cessation, the visualized adduction of the larynx in inspiration is reflected in a paroxystic increase in Rrs. While normal breathing has apparently resumed later on during recovery from exercise, the pattern of Rrs in inspiration is observed to reoccur following a deep breath or swallowing. The procedure may thus help diagnosing the site of exercise-induced obstruction when laryngoscopy is not available and identify re-inducers of laryngeal dysfunction.

    The rising popularity of surgery involving the laryngeal framework (surgical medialization of immobile vocal folds, vocal fold tightening, pitch variation, etc.) has resulted in increasing case experience. Little has appeared in the literature regarding complications or long-term results of this type of surgery. Several years' experience in a major referral center with various types of laryngeal framework surgery has led to a small number of complications. These have included late extrusion of the prosthesis and delayed hemorrhage. A review of these complications and recommendations for modification of technique to minimize them in the future are discussed.
