    To evaluate the role of curative radiotherapy and salvage surgery in patients with T1, T2 glottic cancer. Between June 1989 and December 1994, 23 patients with early glottic cancer, 18 with T1N0M0 and 5 with T2N0M0, were treated with radiotherapy at Gyeongsang University Hospital. All patients were male. Median follow-up period was 46 months, and 100% were observed for at least 3 years. Actuarial survival rates at 5 years were 84.3% for 23 patients. The 5-year actuarial survival rates were 94.4% for T1 and 53.3% for T2 (P=0.05). The 5-year local control rates was 70.0% for T1 and 60.0% for T2 (P=0.44). Of 8 patients with treatment failure, 6 patients (75.0%) were salvaged with surgery. After surgical salvage, the 5-year local control rates were 87.2% for T1 and 80.0% for T2 (p=0.55). In early stage (Stage I and II) glottic cancer, curative radiotherapy can be a treatment of choice and surgery reserved for salvage of radiotherapy failure. (author)

    Reported is the case of a 46-year-old male with hypothyroidism after radiotherapy for early glottic cancer, T1N0M0, Stage I. Six months after 60 Co irradiation 66 Gy with the radiation field size of 5 x 5 cm was given, the clinical signs of acute hypothyroidism was presented. Retrospective CT examinations proved that over 80% of the total dose was irradiated to about 10% of whole thyroid volume. Since laboratory examinations revealed high serum level of thyrogobrin antibody, we postulated immunological mechanism was associated with the onset of hypothyroidism. (author)

    The control of early glottic cancer is equally satisfactory with either surgical resection or radiation therapy; this last method gives the patient good functional results. During the period from 1/1978 to 12/1985, 73 patients with early glottic carcinoma (T1 N0 M0) were treated in the Institute of Radiotherapy L. Galvani, University of Bologna; 45 were stage T1a (tumor limited to one vocal cord) and 28 were stage T1b (tumor of both vocal cords or involving anterior commissure); radiation treatment utilized a 60 Co machine and 5x5 cm fields; the median dose was 67.2 Gy (range 50-76) with conventional fractionation. Ten patients had local recurrence; the median time of recurrence was 13.4 months; 9/10 were treated by surgery and 2/10 died, so the overall control by radiotherapy with surgery in reserve was 100% in T1a tumers and 90.6% in T1b ones. The 5-years disease free survival rate was 93.1% in T1a tumors and 69% in T1b; lesions involving anterior commissure had the worst prognosis, independent of the dose and time-dose factor (3/10 recurrences in the group treated with TDF less than 110 and 4/18 recurrences in the group with TDF more than 110)

    Full Text Available ObjectiveDysphonia is common among patients with early stage glottic cancer. 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.

    Background and purpose: In the majority of patients irradiated for early glottic cancer an abnormal voice was reported. The purpose of the study was to determine the factors influencing voice quality after radiotherapy for T1 glottic cancer. Methods: The voices of 75 male patients irradiated for T1 glottic carcinoma were assessed subjectively and objectively by acoustic analyses and aerodynamic measurements. The laryngeal function and morphology were evaluated by videolaryngostroboscopy. The data on smoking habits, the associated diseases influencing voice quality, the extent of the tumor, the type of biopsy, and the irradiation technique were collected from the medical records. The data on the factors influencing voice quality were compared for patients with a normal/near-normal voice and those with a hoarse voice. Results: Voice quality was at least slightly abnormal in 94.7% and 81.3% of patients, when assessed perceptively and objectively, respectively. Smoking after the completed treatment, more severe morphologic alterations of the vocal folds, dryness of the throat, incomplete closure of the vocal folds and functional voice disorders expressed as supraglottic activity adversely influenced the voice quality. A good correlation between the perceptive voice assessment and the acoustic analyses was established. Conclusions: After the successful irradiation for T1 glottic carcinoma, the great majority of the patients have at least a slightly hoarse voice. A better voice outcome could be achieved if radiotherapy was followed by the patient's cessation of smoking and the appropriate voice therapy.

    Purpose: After treatment for early glottic cancer, a considerable number of patients end up with voice problems interfering with daily life activities. A 5-item screening questionnaire was designed for detection of voice impairment. The purpose of this study is to assess psychometric properties of this questionnaire in clinical practice. Methods and Materials: The questionnaire was completed by 110 controls without voice complaints and 177 patients after radiotherapy or laser surgery for early glottic cancer. Results: Based on normative data of the controls, a score of 5 or less on at least 1 of the 5 questions was considered to state overall voice impairment. Reliability of the questionnaire proved to be good. Voice impairment was reported in 44% of the patients treated with radiotherapy vs. 29% of the patients treated with endoscopic laser surgery. Conclusions: The questionnaire proved to be a reliable, valid, and feasible method to detect voice impairment in daily life. The questionnaire is easy to fill in, and interpretation is straightforward. It is useful for both radiation oncologists and otorhinolaryngologists in their follow-up of patients treated for early glottic cancer

    Background This study compared the risk of fatal cerebrovascular accidents (CVA) in patients with early stage glottic larynx cancer receiving surgery or external beam radiation therapy (EBRT). Methods and Materials Using a competing risks survival analysis, we compared the risk of death due to CVA among patients with early stage glottic larynx cancer receiving surgery or EBRT in the SEER database. Results The cumulative incidence of fatal CVA at 15 years was higher in patients receiving EBRT (2.8 %; 95% CI 2.3%–3.4%) compared to surgery (1.5 %; 95% CI 0.8 %–2.3%, p= 0.024). In multivariable competing risks regression models, EBRT remained associated with an increased risk of fatal CVA compared to surgery (adjusted HR 1.75; 95% CI 1.04–2.96, p= 0.037). Conclusion Treatment of early stage glottic larynx cancer with EBRT was associated with a small increase in the risk of late fatal CVA events relative to surgery. PMID:23595858

    To compare the dose distribution between carotid sparing intensity modulated radiotherapy (IMRT) and opposed lateral field technique (LAFT), and to determine the effects of carotid sparing IMRT in early glottic cancer patients who have risk factors for atherosclerosis. Ten early glottic cancer patients were treated with carotid sparing IMRT. For each patient, the conventional LAFT plan was developed for comparison. IMRT and LAFT plans were compared in terms of planning target volume (PTV) coverage, conformity index, homogeneity index, and the doses to planning organ at risk volume (PRV) for carotid arteries, spinal cord and pharyngeal constrictor muscle. Recurrence was not observed in any patients during the follow-up period. V95% for PTV showed no significant difference between IMRT and LAFT plans, while V100% was significantly higher in the IMRT plan (95.5% vs. 94.6%, p = 0.005). The homogeneity index (11.6%) and conformity index (1.4) in the IMRT plan were significantly better than those in the LAFT plans (8.5% and 5.1, respectively) (p = 0.005). The median V5Gy (90.0%), V25Gy (13.5%), and V50Gy (0%) for carotid artery PRV in the IMRT plan were significantly lower than those in the LAFT plan (99.1%, 89.0%, and 77.3%, respectively) (p = 0.005). Our study suggests that carotid sparing IMRT can significantly decrease the dose to carotid arteries compared to LAFT, and it would be considered for early glottic cancer patient with high risk of atherosclerosis.

    Objectives: Laser cordectomy is very popular nowadays and become one of the treatments of choice for early glottis carcinoma. Transoral laser microsurgery has many advantages comparing conventional open surgery or radiation therapy. In this study, we examined the oncologic results of laser cordectomy for early glottic cancer and analyzed the prognostic impact on the survival of the several tumor-related and treatment-related factors. Methods: Patients who were diagnosed as early glottic squamous cell carcinoma, treated by laser cordectomy with curative intent were analyzed. Patients with preivous radiation therapy were included. From June 1988 to March 2005, 202 patients from five hospitals were analyzed (174 T1, 28 T2). Results: Five-year overall survival and disease-free survival were 98.4% and 84.9%. Twenty two patients developed local recurrence. Total laryngectomy was done in 6 patients and laryngeal preservation rate was 97%. Recurrence was higher in the patients with anterior commissure involvement (9/39) than without anterior commissure involvement (13/163). Recurrence was higher in T1b (4/15) than T1a (13/159). Previous radiation was also highly related to the recurrence (7/20 vs 15/182). Twenty patients with local recurrence after radiation therapy were treated by salvage laser cordectomy. Of them, 7 patients developed local recurrence and 5 year disease-free survival was 57%. Complication was rare with one case of hemorrhage. Tracheotomy was not necessary in all patients. Conclusions: Laser cordectomy for early glottic carcinoma showed high survival, laryngeal preservation rate and low complication rate. The prognostic factors were anterior commissure involvement, both vocal fold involvement and previous radiotherapy.

    Aims: To prospectively analyze the objective voice quality before and after radiotherapy (RT) for early glottic cancer and to evaluate the role of different factors that may affect it. Methods: Patients with T1-T2N0M0 glottic cancer underwent voice quality assessment before treatment and after radical RT. Post-RT voice quality was compared to the voice at diagnosis and the voice of healthy individuals used as controls. A comprehensive set of voice parameters were measured. The effects of age, smoking history, T stage, anterior commissure (AC) involvement, radiation dose, fractionation and volumes on pre-treatment and post-treatment voice quality were analyzed. Results: The voice quality data of 50 patients were analyzed. Following treatment, there was a significant improvement in the majority of measured parameters. However, perturbation and HNR remained inferior compared to controls. A history of smoking, AC involvement and larger RT volumes resulted in poorer voice parameters following RT. There was no significant impact of age alone. T2 tumors had an inferior voice quality before treatment, but did not remain inferior following RT. Hypofractionated RT did not show any negative impact. Conclusions: There is a considerable improvement of voice quality following RT. Several factors may have specific effects on pre-treatment and post-treatment voice

    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.

    T2 patients was observed (p = 0.003). In patients unsuitable for voice sparing operation, 87% of T1 and 50% of T2 patients in primary radiotherapy group finally had their larynx preserved. Conclusions: Stratification based on criteria of possibility for initial voice-sparing operation is important when comparing primary surgery with primary radiotherapy treatment in early glottic cancer. The detrimental effect of prolonged treatment time of irradiation resulted not only in inferior local control rate but also in worse final larynx preservation

    To compare post treatment quality of life (QoL) of patients treated by radiotherapy or endoscopic transoral endolaryngeal surgery using two quality of life scoring tools. From May 1998 to July 2005, 48 patients (11 women and 37 men) with early glottic cancer were treated with curative radiotherapy (18 patients) or laser cordectomy (30 patients), and retrospectively evaluated using QoL questionnaires; European Organization for Research and Treatment of Cancer (EORTC) - EORTC-QoL Core Questionnaire (QLQ-C30 version 2.0) and organ specific EORTC - QLQ, Head and Neck Module (QLQ-H and N35) at the University Hospital Motol, Czech Republic. Mean follow-up was 24 months. Only patients in complete remission were enrolled in the study. The overall score calculated separately for both questionnaires was not statistically different between both groups. Statistically significant differences were found only in specific group of questions focusing on saliva production (p=0.034) and sexuality performance (p=0.002). The majority of cases treated with cordectomy were Tis lesions. In the radiotherapy group, T1 lesions predominated (p=0.0001). Patients treated with radiotherapy were significantly older than those treated with cordectomy (p=0.027), which could explain the worsened score in sexuality questions. There were no significant differences found between genders allocated either to cordectomy or radiotherapy group. The overall QoL did not differ between patients treated with cordectomy or radiotherapy, despite the fact that patients treated with radiotherapy had more advanced disease and were older. There was significantly worse saliva and sexuality question score in the radiotherapy group. (author)

    Purpose: To evaluate the impact of pretreatment hemoglobin levels on the recurrence rate of patients with early stage glottic carcinoma treated with definitive radiotherapy. Materials and Methods: Between May 1972 and December 1992, one hundred three patients with stage I or II glottic carcinoma were treated with definitive radiotherapy. The records were reviewed and analyzed for the effects of pretreatment hemoglobin and hematocrit, stage, dose per fraction (180 vs 200 cGy), treatment interruptions, and differentiation of the tumor. The majority of stage I patients were treated to a total dose of 64 to 66 Gy, and stage II patients were treated to 68 to 70 Gy. Mean and median follow up were 85 and 75 months, respectively. Results: With mean follow up of 85 months, the recurrence rate for patients with hemoglobin ≤13 g/dL was 33.3%, and patients with hemoglobin >13 g/dL was 20% (p 0.19). For stage I (n = 84), the recurrence rate with hemoglobin ≤13 g/dL and >13 g/dL was 26% and 17%, respectively (p = 0.51). For stage II patients (n = 19) with hemoglobin ≤13 g/dL and >13 g/dL, the recurrence rate was 50% and 36%, respectively (p = 0.66). Using a Fisher's exact test, the only variables showing a statistically significant prognosis for recurrence were treatment interruption and stage. The recurrence rate with a treatment interruption was 40% compared with 15% if there was no interruption (p 0.0039). The recurrence rate for stage I was 19%, and for stage II was 42% (p = 0.067). Other factors showed no significant increase in recurrence; dose per fraction (p = 0.421), grade of differentiation (p = 0.740). Conclusion: While pretreatment hemoglobin levels below 13 g/dL do not significantly affect the recurrence rates for T1N0 and T2N0 glottic carcinomas, treatment interruptions are a significant factor in the failure of these patients

    Purpose: Comprehensive neck radiation therapy (RT) has been shown to increase cerebrovascular disease (CVD) risk in advanced-stage head-and-neck cancer. We assessed whether more limited neck RT used for early-stage (T1-T2 N0) glottic cancer is associated with increased CVD risk, using the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database. Methods and Materials: We identified patients ≥66 years of age with early-stage glottic laryngeal cancer from SEER diagnosed from 1992 to 2007. Patients treated with combined surgery and RT were excluded. Medicare CPT codes for carotid interventions, Medicare ICD-9 codes for cerebrovascular events, and SEER data for stroke as the cause of death were collected. Similarly, Medicare CPT and ICD-9 codes for peripheral vascular disease (PVD) were assessed to serve as an internal control between treatment groups. Results: A total of 1413 assessable patients (RT, n=1055; surgery, n=358) were analyzed. The actuarial 10-year risk of CVD was 56.5% (95% confidence interval 51.5%-61.5%) for the RT cohort versus 48.7% (41.1%-56.3%) in the surgery cohort (P=.27). The actuarial 10-year risk of PVD did not differ between the RT (52.7% [48.1%-57.3%]) and surgery cohorts (52.6% [45.2%-60.0%]) (P=.89). Univariate analysis showed an increased association of CVD with more recent diagnosis (P=.001) and increasing age (P=.001). On multivariate Cox analysis, increasing age (P<.001) and recent diagnosis (P=.002) remained significantly associated with a higher CVD risk, whereas the association of RT and CVD remained not statistically significant (HR=1.11 [0.91-1.37,] P=.31). Conclusions: Elderly patients with early-stage laryngeal cancer have a high burden of cerebrovascular events after surgical management or RT. RT and surgery are associated with comparable risk for subsequent CVD development after treatment in elderly patients

    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.

    The outcomes of 27 patients with glottic cancer extending into the subglottis (GCSE) who were treated by surgery and radiation (n=17) or radiation alone (n=10) during a 13-year period were retrospectively reviewed. Since this study was nonrandomized and retrospective, the patient groups were not equally matched with regard to age (p>0.05), gender (p>0.30), or disease stage (p>0.05). The locoregional failure rate was 18±(95% CI) 20% in patients who received combined therapy and 40±31% in persons treated by radiation alone (p=0.20); the corresponding survival rates at two years were 53±24% and 42±31% (p>0.50). These findings suggest that GCSE may be better managed by a combination of surgery and radiotherapy than by the use of radiotherapy alone. (author)

    Full Text Available Abstract Background In this study, we aim to gather information about the quality of life issues, functional outcomes and voice problems facing early glottic cancer patients treated with the surgical techniques such as laryngofissure cordectomy, fronto-lateral laryngectomy, or cricohyoidopexi. In particular, consistency of life and voice quality issues with the laryngeal tissue excised during surgery is examined. In addition, the effects of arytenoidectomy to the life and voice quality are also studied. Methods 29 male patients were enrolled voluntarily in the study. The average age was 53.9 years. Three out of 10 patients with laryngofissure cordectomy also had arytenoidectomy. 11 patients had fronto-lateral laryngectomy with Tucker reconstruction, two of which also had arytenoidectomy. There were eight patients with cricohyoidopexi and bilateral functional neck dissection. Three of these patients also had arytenoidectomy. In bilateral functional neck dissection cases, spinal accessory nerve was preserved and level V of the neck was not dissected. None of the patients had neither radiotherapy nor voice therapy. Cordectomy patients never had a temporary tracheotomy or were connected to a feeding tube. Data was collected for 13 months for the cordectomy group, 14 months for fronto-lateral laryngectomy and cricohyoidopexi groups on average post-operatively. Statistical analysis in this study was carried out using the one-way analysis of variance, and the Post-Hoc group comparisons were made after Bonferroni and Scheffé-procedures. In order to determine the effects of arytenoidectomy, a regression analysis is carried out to see if there are statistical differences in answers given to the survey questions among patients who were arytenoidectomized during their surgeries. Results There was a statistically significant difference between cordectomy and cricohyoidopexi group in answers to the University of Washington- Quality of Life- Revised survey

    We treat early glottic squamous cell carcinoma with chemoradiation and evaluate the effects of the chemoradiation at the dose of 30-40 Gy as an intermediate evaluation. To investigate the need for this intermediate evaluation, we retrospectively analyzed 97 patients, 92 men and 5 women aged 36 to 86 years, with glottic squamous cell carcinoma at stage I and II treated at our institution from January 2000 to May 2007. The three-year survival rate was 98% in all cases, 100% in T1a, 93% in T1b and 94% in T2. The three-year preservation rate of the larynx was 92% in all cases, 98% in T1a, 93% in T1b and 83% in T2. In the intermediate evaluation, complete response was 78% in T1a, 85% in T1b and 53% in T2. In cases of larynx preservation, the recurrence rate of the primary site was significantly higher in cases without complete response in the intermediate evaluation than in cases with complete response (p<0.05). It seemed that the not complete response case in the intermediate evaluation paid attention to a primary tumor recurrence in particular and needed careful follow-up. (author)

    was equal to 23%, with second tumor deaths being more frequent than larynx cancer deaths (67 of 831 vs. 46/831). Conclusion: The results of this study support the opinion, suggested by some international guidelines, that radiotherapy is standard treatment for T1 glottic cancer. Better results are obtained in patients with less extended disease and with 4-6 MV photon beams. The use of doses in excess of 65 Gy and of field sizes of 36-49 cm 2 is probably the best technical choice available. Late damage is infrequent, but careful follow-up is warranted to detect early not only relapses (because conservative salvage surgery is feasible), but also second malignant tumors, which constitute the main cause of death in these patients and are potentially curable

    Purpose: To retrospectively evaluate local control rates, late damage incidence, functional results, and second-tumor occurrence according to the different patient, tumor, and treatment features in a large bi-institutional series of T2 glottic cancer. Methods and Materials: A total of 256 T2 glottic cancer cases treated consecutively with radical intent at the Florence University Radiation Oncology Department (FLO) and at the Radiation Oncology Department of University of Brescia, Istituto del Radio 'O. Alberti' (BS) were studied. Cumulative probability of local control (LC), disease-specific survival (DSS), and overall survival (OS) rates were calculated and compared in the different clinical and therapeutic subgroups by both univariate and multivariate analysis. Types of relapse and their surgical salvage were evaluated, along with the functional results of treatment. Late-damage incidence and second-tumor cumulative probability (STP) were also calculated. Results: In the entire series, 3-year, 5-year, and 10-year OS rates were, respectively, 73%, 59%, and 37%. Corresponding values for cumulative LC probability were 73%, 73%, and 70% and for DSS, 89%, 86%, and 85%, taking into account surgical salvage of relapsed cases. Seventy-three percent of the patients were cured with function preserved. Main determinants of a worse LC at univariate analysis were larger tumor extent and impaired cord mobility. At multivariate analysis, the same factors retained statistical significance. Twenty-year STP was 23%, with second-tumor deaths less frequent than larynx cancer deaths (20 of 256 vs. 30 of 256). Incidence of late damage was higher in the first decade of accrual (22%) than in the last decade (10%, p = 0.03); the same was true for severe late damage (9% vs. 1.8%). Conclusion: Present-day radical radiotherapy can be considered a standard treatment for T2 glottic cancer. Better results are obtained in patients with less extended disease. Late damage is relatively

    Purpose: This population-based study describes the treatment of early glottic cancer in Ontario, Canada and assesses whether treatment variations were associated with treatment effectiveness. Methods and Materials: We studied 491 T1N0 and 213 T2N0 patients. Data abstracted from charts included age, sex, stage, treatment details, disease control, and survival. Results: The total dose ranged from 50 to 70 Gy, and the daily dose ranged from 1.9 to 2.8 Gy. In 90%, treatment duration was between 25 and 50 days. Field sizes, field reductions, beam arrangement, and beam energy varied. Late treatment breaks occurred in 13.6% of T1N0 and 27.1% of T2N0 cases. Local control was comparable to other reports for T1N0 (82% at 5 years), but was only 63.2% in T2N0. Variables associated with local failure in T1N0 were age less than 49 years (relative risk [RR], 3.21; 95% confidence interval [CI], 1.49-6.90) and >3 treatment interruption days (RR, 2.43; 95% CI, 1.00-5.91). In T2N0, these were field reduction (RR, 2.33; 95% CI, 1.23-4.42) and late treatment breaks (RR, 2.19; 95% CI, 1.09-4.41). Conclusion: Some aspects of treatment for early glottic cancer were associated with worse local control. Problems with protracted treatment are of particular concern, underscoring the need for randomized studies to intensify radiotherapy

    To analyze various parameters affect local control, we reviewed the results of radiotherapy for early glottic carcinoma. Between 1977 and 1997, 64 patients with untreated early glottic carcinoma and four patients with recurrent early glottic carcinoma were analyzed retrospectively. All tumors were classified as follows; T1 (n=56), T2 (n=12); well differentiated (n=33), moderately (n=25), poorly (n=1), unknown (n=9); very small tumor (VST) (n=46), small tumor (ST) (n=22). All patients were treated utilizing a cobalt-60 unit to a total dose that ranged from 56 Gy to 64 Gy (mean 60 Gy). The mean treatment time was 44 days (range 38-49). The local control rates at 2 years and 5 years for all patients were 85% and 78%, respectively. On univariate analysis, tumor size (p=0.0146) and recurrent or untreated tumor (p=0.0226) affected local control. On multivariate analysis, tumor size (p=0.0273) and recurrent or untreated tumor (p=0.0495) were also significant factors that affected local control. (author)

    The purpose of the present paper was to review the results of treating early stages glottic, squamous cell carcinoma by radiotherapy in the Department of Radiation Oncology, Prince of Wales Hospital, Sydney. A retrospective review was carried out of all patients seen in the department from 1967 to 1994, inclusive. To be eligible, patients had to have newly diagnosed cancer and to have been treated with curative intent by radiotherapy alone. Three hundred and sixty-nine patients satisfied the eligibility requirements. The mean follow-up time was 12.2 years (maximum: 28 years). At 5 years the actuarial local control rate was 80% (84% for stage T 1 and 72% for T 2 ). The ultimate local control rate was 96%. The overall survival rates at 5 and 10 years were 73% and 52%, respectively. The risk of nodal recurrence was much higher after persisting disease or local recurrence. Our results confirm the high cure rates achieved with this modality of treatment and are comparable with those reported in the literature. Copyright (1999) Blackwell Science Pty. Ltd

    Purpose: Treatment and disease-related factors were analyzed for their influence on the outcome of patients treated definitively with irradiation (RT) for early glottic carcinoma. Methods and Materials: One hundred two patients with stage T1 or T2 glottic carcinomas were treated definitively with RT from December 1983 through September 1993. Median follow-up time was 63 months. Factors analyzed for each patient included age, sex, stage, anterior commissure involvement, surgical alternative, histologic differentiation, field size, total dose, fraction size, and total treatment time. Survival analysis methods were employed to assess the effects of these factors on local control and complication rates. Results: The 5-year local control rates by stage were as follows: T1a, 92%; T1b, 80%; T2a, 94%; and T2b, 23%. By univariate analysis, factors found to have a significant impact on local control were stage, surgical alternative, fraction size, anterior commissure involvement, and overall treatment time. By multivariate analysis, stage, field size, and fraction size were the only significant factors that independently influenced local control. Conclusion: The inferior control rate for stage T2b lesions has implications for treatment. Our study supports the conclusion of reports in the literature showing that low fraction size negatively influences outcome in patients with early glottic cancer

    Purpose: To report, from a retrospective analysis of prospectively collected data, on the feasibility, outcome, toxicity, and voice-handicap index (VHI) of patients with T1a glottic cancer treated by a novel intensity modulated radiation therapy technique developed at our institution to treat only the involved vocal cord: single vocal cord irradiation (SVCI). Methods and Materials: Thirty patients with T1a glottic cancer were treated by means of SVCI. Dose prescription was set to 16 × 3.63 Gy (total dose 58.08 Gy). The clinical target volume was the entire vocal cord. Setup verification was done by means of an online correction protocol using cone beam computed tomography. Data for voice quality assessment were collected prospectively at baseline, end of treatment, and 4, 6, and 12 weeks and 6, 12, and 18 months after treatment using VHI questionnaires. Results: After a median follow-up of 30 months (range, 7-50 months), the 2-year local control and overall survival rates were 100% and 90% because no single local recurrence was reported and 3 patients died because of comorbidity. All patients have completed the intended treatment schedule; no treatment interruptions and no grade 3 acute toxicity were reported. Grade 2 acute dermatitis or dysphagia was reported in only 5 patients (17%). No serious late toxicity was reported; only 1 patient developed temporary grade 2 laryngeal edema, and responded to a short-course of corticosteroid. The VHI improved significantly, from 33.5 at baseline to 9.5 and 10 at 6 weeks and 18 months, respectively (P<.001). The control group, treated to the whole larynx, had comparable local control rates (92.2% vs 100%, P=.24) but more acute toxicity (66% vs 17%, P<.0001) and higher VHI scores (23.8 and 16.7 at 6 weeks and 18 months, respectively, P<.0001). Conclusion: Single vocal cord irradiation is feasible and resulted in maximal local control rate at 2 years. The deterioration in VHI scores was slight and temporary and

    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. We report here on a case of laryngeal amyloidosis in a 47-year-old man who suffered from progressive dyspnea

    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

    We analyzed the influence of various parameters on the results of radiotherapy for T1 glottic cancer by assessing the outcomes of 60 patients with this cancer who received definitive radiotherapy between 1985 and 1994. Seven patients were treated with a cobalt-60 unit, and the other 53 with a linear accelerator (26 patients at 3-MV, 10 at 6-MV, and 17 at 10-MV). Of the 17 patients treated at 10-MV, 4 also received part of their treatment with a cobalt-60 unit. The total radiation dose ranged from 56 Gy to 70 Gy (mean, 61 Gy). The total radiation dose of 51 patients (85%) was 60 Gy. The factors found to influence local control were the strength of the radiation beam energy and whether or not there was gross tumor invasion of the anterior commissure. The local control rate was 71% in the patients treated with a 10-MV linear accelerator, 56% in those treated with a 6-MV linear accelerator and, 97% in those treated with a cobalt-60 unit or a 3-MV linear accelerator (P=0.0173). The local control rate was 43% in the patients with gross anterior commissure invasion and 88% in those without (P=0.0075). We conclude that low energy photon beams are more suitable for the treatment of early glottic cancers, especially if the lesion grossly invades the anterior commissure. (author)

    From 1967 through 1985, 358 cases of early glottic carcinoma were treated with telecobalt therapy at the Department of Radiology, Osaka University Medical School. Among 278 cases treated with 2 Gy a day, the tumor response of 262 cases at 40, 50 and 60 Gy were evaluated by direct or indirect laryngoscope. The five-year local control rates of these evaluable cases of T1 and T2 glottic carcinoma were 79% and 70%, respectively. The local control rates of T1 glottic carcinoma with tumor clearance and persistence at 40 Gy were 83% (119/143) and 64% (43/67), and those of T2 cases were 86% (18/21) and 58% (18/31), respectively. The local control rates of the cases with tumor clearance and persistence at 40 Gy were same between T1 and T2 cases. The tumor clearance rates of T1 cases were significantly higher than those of T2 cases (p [de

    This report analyzes dose-time-volume factors in 112 patients with T3N0M0 glottic cancer who were treated with radical radiotherapy with surgery for salvage between 1963 and 1977. 55% of the patients are alive and well 5 years following treatment; 26% died of glottic cancer and 19% died of intercurrent disease. In the 1965 to 1969 time period, 31% died of tumor as compared to 16% in the 1975 to 1977 time period. Overall local control by radiotherapy was 51%; 2/3 of the failures were surgically salvaged. 44% were locally controlled by radiotherapy in the 1965 to 1969 time period and 57% in the 1975 to 1977 time period. Analysis of dose-time-volume factors reveals that the optimal dose is greater than 1700 ret and a minimal volume of 6 x 8 cm should be used. A dose-cure curve for T3 glottic cancer is constructed and compared with the dose complication curve for the larynx and the dose-cure curve for T1N0M0 glottic cancer. A comparison of cure rates between 112 patients treated with radical radiotherapy and surgery for salvage versus 28 patients treated with combined pre-operative irradiation and surgery reveals no difference in the proportion of patients who died of glottic cancer or in the number of patients alive at 5 years following treatment

    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)

    The aim of this study was to quantify the impact of initial tumor volume (TV) on radiotherapy (RT) outcome in patients with T2 glottic cancer. Initial TV was calculated for 115 consecutive patients with T2 glottic cancer who had been treated with definitive RT alone at a single institution. The results showed strong correlations of TV with 3-year local tumor control (LTC) and disease-free survival (DFS). For TV ≤ 0.7 cm 3 , 3-year LTC was 83 %; for TV 0.7-3.6 cm 3 this was 70 % and for TV 3.6-17 cm 3 44 %. Analysis of total dose vs. initial TV showed that larger T2 glottic tumors with a TV of around 5 cm 3 (2-2.5 cm in diameter with 10 10 cancer cells) need an extra 6.5 Gy to achieve similar 3-year LTC rates as for small tumors with a TV of 0.5 cm 3 (∝1 cm in diameter with 10 9 cancer cells). Although classification of tumors according to TV cannot replace TNM staging in daily practice, it could represent a valuable numerical supplement for planning the optimal dose fractionation scheme for individual patients.

    Purpose: To investigate the dosimetry and feasibility of carotid-sparing intensity-modulated radiotherapy (IMRT) for early glottic cancer and to report preliminary clinical experience. Methods and Materials: Digital Imaging and Communications in Medicine radiotherapy (DICOM-RT) datasets from 6 T1-2 conventionally treated glottic cancer patients were used to create both conventional IMRT plans. We developed a simplified IMRT planning algorithm with three fields and limited segments. Conventional and IMRT plans were compared using generalized equivalent uniform dose and dose-volume parameters for in-field carotid arteries, target volumes, and organs at risk. We have treated 11 patients with this simplified IMRT technique. Results: Intensity-modulated radiotherapy consistently reduced radiation dose to the carotid arteries (p < 0.05) while maintaining the clinical target volume coverage. With conventional planning, median carotid V35, V50, and V63 were 100%, 100%, and 69.0%, respectively. With IMRT planning these decreased to 2%, 0%, and 0%, respectively (p < 0.01). Radiation planning and treatment times were similar for conventional radiotherapy and IMRT. Treatment results have been excellent thus far. Conclusions: Intensity-modulated radiotherapy significantly reduced unnecessary radiation dose to the carotid arteries compared with conventional lateral fields while maintaining clinical target volume coverage. Further experience and longer follow-up will be required to demonstrate outcomes for cancer control and carotid artery effects.

    To compare oncological outcome and voice quality among a uniform and well-defined subset of patients with T1 glottic carcinoma. Patients, affected by laryngeal glottic carcinoma, treated by laser CO 2 surgery or radiotherapy, have been analyzed. Overall survival and disease-free survival were calculated. In order to verify differences in functional outcomes and voice quality, all patients were interviewed during their last follow-up visit during 2009 using the VHI (Voice Handicap Index) questionnaire. The data were analyzed using the MedCalc software. A total of 143 patients were analyzed: 73 underwent surgery and 70 underwent radiotherapy. No statistically significant differences were found between the two groups in terms of overall survival and disease-free survival; dividing patients into stages T1a and T1b also made no difference. In order to evaluate the differences in outcomes for surgery and radiotherapy, patients were interviewed using the VHI questionnaire. Better scores for each category in the VHI were found for patients receiving radiotherapy compared to surgery (physical: p = 0.0023; functional: p < 0.0001; environmental: p < 0.001). The median VHI score for radiotherapy patients was 4, while for surgical patients it was 18 (p < 0.0001). This study confirms the well-known knowledge that results from radiotherapy and surgery in early glottic cancer treatment are equivalent. Furthermore, the role of patient preference in the treatment modality choice and the value of a multidisciplinary approach for a detailed and multi-oriented discussion with the patient are outlined.

    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)

    Purpose: to assess the patterns of failure in the treatment of early-stage squamous cell carcinoma of the glottic larynx. Patients and methods: between 1983-2000, 122 consecutive patients treated for early laryngeal cancer (UICC T1N0 and T2N0) by radical radiation therapy (RT) were retrospectively studied. Male-to-female ratio was 106: 16, and median age 62 years (35-92 years). There were 68 patients with T1a, 18 with T1b, and 36 with T2 tumors. Diagnosis was made by biopsy in 104 patients, and by laser vaporization or stripping in 18. Treatment planning consisted of three-dimensional (3-D) conformal RT in 49 (40%) patients including nine patients irradiated using arytenoid protection. A median dose of 70 Gy (60-74 Gy) was given (2 Gy/fraction) over a median period of 46 days (21-79 days). Median follow-up period was 85 months. Results: the 5-year overall, cancer-specific, and disease-free survival amounted to 80%, 94%, and 70%, respectively. 5-year local control was 83%. Median time to local recurrence in 19 patients was 13 months (5-58 months). Salvage treatment consisted of surgery in 17 patients (one patient refused salvage and one was inoperable; total laryngectomy in eleven, and partial laryngectomy or cordectomy in six patients). Six patients died because of laryngeal cancer. Univariate analyses revealed that prognostic factors negatively influencing local control were anterior commissure extension, arytenoid protection, and total RT dose < 66 Gy. Among the factors analyzed, multivariate analysis (cox model) demonstrated that anterior commissure extension, arytenoid protection, and male gender were the worst independent prognostic factors in terms of local control. Conclusion: for early-stage laryngeal cancer, outcome after RT is excellent. In case of anterior commissure extension, surgery or higher RT doses are warranted. Because of a high relapse risk, arytenoid protection should not be attempted. (orig.)

    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)

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

    Early glottic carcinomas (T1 and T2) constitute only 2% of all laryngeal cancers in our data. Seventy patients were seen between 1985 and 1992. All patients were treated by cobalt-60 small field radiotherapy using a beam directed shell. The total dose delivered was 60-65Gy in 31 patients and 66-70Gy in 39 patients. The follow-up period ranged from 5 to 126 months, with a mean follow up of 37 months overall and 55 months in the surgical salvage group. Radiation therapy controlled disease in 71% (50 of 70) of patients overall; 75% with T1 and 67% with T2 lesions. Total laryngectomy as salvage surgery was performed in 70% (14 of 20) of patients whose disease recurred. Ultimate control including surgical salvage occurred in 64 (91 %) of 70 patients in the present study. The actuarial 5 year survival was 83 and 80% in T1 and T2 tumours, respectively (statistically insignificant). This report supports the policy of definitive irradiation, reserving surgical salvage for radiation failures in early laryngeal cancers. 17 refs., 2 tabs

    The existing predictive models of laryngeal cancer recurrence present limitations for clinical practice. Therefore, we constructed, internally validated and implemented in a mobile application (Android) a new model based on a points system taking into account the internationally recommended statistical methodology. This longitudinal prospective study included 189 patients with glottic cancer in 2004-2016 in a Spanish region. The main variable was time-to-recurrence, and its potential predictors were: age, gender, TNM classification, stage, smoking, alcohol consumption, and histology. A points system was developed to predict five-year risk of recurrence based on a Cox model. This was validated internally by bootstrapping, determining discrimination (C-statistics) and calibration (smooth curves). A total of 77 patients presented recurrence (40.7%) in a mean follow-up period of 3.4 ± 3.0 years. The factors in the model were: age, lymph node stage, alcohol consumption and stage. Discrimination and calibration were satisfactory. A points system was developed to obtain the probability of recurrence of laryngeal glottic cancer in five years, using five clinical variables. Our system should be validated externally in other geographical areas. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Purpose: We investigated the dosimetric benefit and treatment efficiency of carotid-sparing TomoHelical (TH) three-dimensional conformal radiotherapy (3DCRT) for early glottic cancer. Methods: Computed tomography (CT) simulation was performed for 10 patients with early-stage (T1N0M0) glottic squamous cell carcinoma. The clinical target volume, planning target volume (PTV), carotid artery (CA), and spinal cord (SP) were delineated for each CT data set. Two-field 3DCRT (2F-3DCRT), three-field intensity-modulated radiation therapy (IMRT) (3F-IMRT), TomoHelical-IMRT (TH-IMRT), and TH-3DCRT plans were generated, with a total prescribed dose of 67.5 Gy in 30 fractions to the PTV for each patient. In order to evaluate plan quality, dosimetric characteristics were compared in terms of the conformity index (CI) and homogeneity index (HI) for the PTV, V35, V50, and V63 for the CAs and in terms of the maximum dose for the SP. Additionally, treatment planning and delivery times were compared to evaluate treatment efficiency. Results: The CIs for 3F-IMRT (0.650±0.05), TH-IMRT (0.643±0.03), and TH-3DCRT (0.631±0.03) were much better than that for 2F-3DCRT (0.318±0.03). The HIs for TH-IMRT (1.053±0.01) and TH-3DCRT (1.055±0.01) were slightly better than those for 2F-3DCRT (1.062±0.01) and 3F-IMRT (1.091±0.007). 2F-3DCRT showed poor CA sparing in terms of the V35, V50, and V63 compared to 3F-IMRT, TH-IMRT, and TH-3DCRT (p<0.05), whereas there was no significant dose difference between 3F-IMRT, TH-IMRT, and TH-3DCRT (p>0.05). The maximum dose to the SP with all plans was below 45 Gy. The treatment planning times for 2F-3DCRT (5.9±0.66 min) and TH-3DCRT (7.32±0.94 min) were much lower than those for 3F-IMRT (45.51±2.76 min) and TH-IMRT (35.58±4.41 min), whereas the delivery times with all plans was below 3 minutes. Conclusion: TH-3DCRT showed excellent carotid sparing capability, comparable to that with TH-IMRT, with high treatment efficiency and short planning and

    Purpose/Objective: Recent reports have suggested that pretreatment hemoglobin (Hgb) is significantly associated with local control (LC) and overall survival (OS) in patients with T1 and T2 squamous cell carcinoma of the glottic larynx. This study evaluates the association of pretreatment Hgb level and other factors with outcome in patients limited to T1 squamous cell carcinoma of the glottic larynx treated with external beam radiation. Methods: One hundred fifty-eight patients with T1 squamous cell carcinoma of the glottic larynx were analyzed. Median follow-up was 5 years (range 2-22). Median pretreatment Hgb was 14.4 gm/dl (range 8.2-17.2). The following parameters were analyzed for their impact on LC, OS, and disease specific survival (DSS): age, gender, pretreatment Hgb, tumor grade, anterior commissure involvement, field size, total dose, dose per fraction, and overall treatment time. Results: Five year actuarial LC was 84%. Pretreatment Hgb was not a significant predictor for LC when assessed as a continuous variable (p=0.38). LC was 82% for patients with Hgb >13 vs 92% for Hgb ≤ 13 (p=0.13). No other factor was significant for LC. Five year actuarial OS was 74%. On univariate analysis, pretreatment Hgb ≤ 13 gm/dl was a significant factor for poorer OS (78% vs 68%, p=0.004), as were total dose 61 years (p=0.017). On multivariate analysis, only age >61 (p=0.014) and Hgb ≤ 13 (p=0.001) retained significance for OS. Five year actuarial DSS was 92%. Pretreatment Hgb was not a prognostic factor for DSS, nor were any other analyzed factors. Conclusion: Pretreatment Hgb is not a significant prognostic factor for LC in patients with T1 squamous cell carcinoma of the glottic larynx, but it does predict for a poorer OS without affecting DSS. This suggests that patients with lower pretreatment Hgb may have confounding medical problems which detract from their overall survival

    A Phase I/II study of S-1 combined radiation therapy was conducted in patients with Stage II (T2N0) glottic cancer. The purpose of the Phase I study was to identify the maximum tolerated dose, the recommended dose and the dose limiting toxicity. The objectives in the phase II study were to estimate the local control and the overall survival, and the incidence of adverse events. In Phase I, S-1 was administered orally in a split-course fashion as two doses of 40 mg/m 2 , for a total daily dose of 80 mg/m 2 . The course involved a 2-week rest after a 2-week administration (Level 1) and a 1-week rest after a 3-week administration (Level 2). Radiation therapy was administered in 2-Gy daily (total 60-Gy) standard fractionation. Seven patients were enrolled in the Phase I, and 19 in the Phase II study. Mucositis was the most common toxicity encountered. All 26 patients completed radiation therapy without delay. The overall response rate was 100% (26/26) with all patients showing a complete response. One patient developed a local recurrence 28 months after the treatment. The 3-year local control and overall survival rates were 94.7 and 85.4%, respectively (limited to 22 patients from Level 2). The use of S-1 at 80 mg/m 2 per day in a split-course with 1-week rest during the course of radiation therapy was safe and effective for Stage II glottic cancer. The treatment strategy employing orally available S-1 proved to be beneficial over the conventional injection of antitumor agents for maintaining the patients' quality of life. (author)

    Purpose: Pretreatment hemoglobin (Hb) level has been reported to be an important prognostic factor for local control and survival in various malignancies. However in many settings, the adverse effect of a low Hb may be related to more advanced disease and the purpose of this analysis was to assess the influence of pretreatment Hb on local control in a large series of patients with a localised cancer (T1/T2 glottic cancer, AJCC 1992) treated in a standard fashion. Materials and Methods: Between Jan 1981 and Dec 1989, 735 patients (median age 63, 657 males 78 females) with T1/T2 glottic cancer were treated with RT. The standard RT prescription was 50Gy in 20 fractions over 4 weeks (97% patients). Factors studied for prognostic importance for local failure included pretreatment Hb (assessed as a continuous variable) age, sex, T category, anterior commissure involvement, subglottic extension, tumour bulk (presence of visible tumour vs subclinical disease), treatment time and RT technique (Cobalt vs 6 MV). Results: With a median follow-up of 6.8 years (range 0.2 - 14.3), 131 patients have relapsed for an actuarial 5-year relapse free rate of 81.7%. The 5-year actuarial survival was 75.8%, cause specific survival - 92.4%. The median pretreatment hemoglobin level was 14.8 g/dl and was the same in all T categories. On multivariate analysis, using the Cox proportional hazards model, pretreatment Hb (p=0.001) predicted for local failure after RT. The relative risk (RR) for relapse was calculated for various Hb levels eg the RR for a Hb of 12 g/dl vs a Hb of 15 g/dl was 1.8, (95% C.I. 1.3 - 2.7). Previously noted factors including gender (p=0.0038), T category (p=0.007)) as well as tumour bulk (p=0.02) were also prognostically important for local control. Conclusions: This analysis, in a large number of similarly treated patients, indicates that pretreatment Hb is an independent prognostic factor for local control in patients with T1/T2 carcinoma of the glottis treated with

    The optimal treatment strategy for stage I-II glottic squamous cell carcinoma (SCC) is not well-defined. This study analyzed treatment results and prognostic factors. This is a single-institution retrospective analysis of 244 patients with T1-2 glottic SCC who underwent normofractionated radiotherapy (RT) and/or surgery between 1990 and 2013. The primary endpoint was relapse-free survival (RFS). Median age was 65 years (range: 36-92 years), the majority (82%) having stage I disease. Definitive RT was used in 82% (median dose: 68 Gy, 2 Gy per fraction). Median follow-up was 59 months. The 5-year RFS rates were 83 and 75% (p = 0.05) for stage I and 62 and 50% (p = 0.47) for stage II in the RT and surgery groups, respectively. Multivariate analyses indicate T1 vs. T2 and RT vs. surgery as independent prognostic factors for RFS, with hazard ratios of 0.38 (95% confidence interval, CI: 0.21-0.72) and 0.53 (95% CI: 0.30-0.99), respectively (p < 0.05). The 5-year overall and cause-specific survival rates in the whole cohort were 92 and 96%, respectively, with no significant differences between treatment groups. Anterior commissure involvement was neither a prognostic nor a predictive factor. The incidence of secondary malignancies was not significantly different between patients treated with and without RT (22 vs. 9% at 10 years, respectively, p = 0.18). Despite a possible selection bias, our series demonstrates improved RFS with RT over surgery in stage I glottic SCC. (orig.)

    Purpose: Different radiotherapy fractionation schedules were used over a 10-year period to treat patients with early squamous cell carcinoma of the vocal cords at McGill University. A retrospective analysis was performed to study the effect of fraction size on local control in this group of patients. Methods and Materials: A total of 126 previously untreated patients with T1 invasive squamous cell carcinoma of the true vocal cords were irradiated between January 1978 and December 1988 in the Department of Radiation Oncology at McGill University. All patients received megavoltage irradiation, 94 patients received daily fractions > 2 Gy (64 patients received 50 Gy with once-daily 2.5-Gy fractions, and 30 received 65.25 Gy in 29 fractions of 2.25 Gy each), and 32 patients were treated to a dose of 66 Gy in 33 fractions with 2 Gy/fraction. Patients' characteristics of prognostic importance were equally distributed between the two fractionation groups. Results: At a median follow-up of 84 months, the 10-year disease-free survival and overall survival were 76% and 93%, respectively. Local control for patients treated with > 2 Gy fraction was 84%, compared to 65.6% for those treated with 2-Gy fractions (p = 0.026). Among the prognostic factors tested, such as gender, age, stage, anterior and posterior commissure involvement, smoking history, and fraction size, the latter was the only significant predictor of local control for the whole group of patients in univariate (p = 0.041) and multivariate (p = 0.023) analysis. There was no observed difference in the incidence of complications between the two fraction groups. Conclusions: From the results of this retrospective review of patients treated with radiotherapy for T1 true vocal cord cancer, and within the range of total doses and overall treatment times used in our patients, it was found that fractionation schedules using daily fraction size > 2 Gy are associated with a better local control than schedules delivering 2 Gy

    , macroscopic tumor, and neck diameter (p = 0.0038). Twenty-eight percent (SE 6%) of the patients who continued smoking had complications at 10 years, compared to about 13% (SE 4%) of those who stopped before or after RT. No evidence was found for any other relation between complications and patient or tumor factors. Severe edema and necrosis (grade III and IV) were not observed in the 2 Gy fraction schedules. A laryngectomy was performed in 36 patients: 30 for recurrence, 3 for complications (at 40, 161, and 272 months), and 3 for a second primary. The overall larynx preservation was 90% at 10 years, and for the different schedules it was 20 x 3.25 Gy: 97%; 20 x 3.1 Gy: 96%; 22 x 2.8 Gy: 92%; 25 x 2.4 Gy: 89%; 33 x 2 Gy: 78%; and 30 x 2 Gy: 80%. Conclusion: Overall treatment time is the most significant factor for locoregional control of T1 glottic cancer. A schedule of 25 x 2.4 Gy appeared to be the optimal treatment schedule considering both tumor control and long term toxicity. The complication rate was increased in patients who continued smoking

    A bibliographical analysis on the subject of early laryngeal cancer (neoplams staged as Tis, T1-T2 N0) was carried out through a bibliographic review of updated articles. The anatomy, epidemiology, generalities, clinical presentation and behavior of cancer were described. The biopsy, the clinical history, the physical examination and radiodiagnostic studies are used for a correct staging and according to the stage, to select the appropriate treatment. Treatment modalities and prescription dose for this type of cancer are compared and explained. The locoregional evaluation of glottic cancer is performed by Computed Axial Tomography (CAT), Nuclear Magnetic Resonance (NMR), Ultrasound (US) and Positron Emission Tomography-Computed Tomography (PET/CT). CAT and NMR have shown to be more accurate in the evaluation of glottic larynx cancer compared with clinical endoscopic examination alone. CAT, NMR, US and PET/CT were clearly more sensitive and specific in the assessment of the neck that only palpation. The preservation of the voice is an important parameter in choosing a therapeutic modality. Radiotherapy has proven to be the most used and known treatment. Radiation therapy with Cobalt 60 is commonly used in Costa Rica for the treatment of early larynx cancer [es

    Full Text Available Abstract Background To evaluate prognostic factors that may influence local control (LC of T1N0 glottic cancer treated by primary radiotherapy (RT with 6 MV photons. Methods We retrospectively reviewed the medical records of 433 consecutive patients with T1N0 glottic cancer treated between 1983 and 2005 by RT in our institution. All patients were treated with 6 MV photons. One hundred and seventy seven (41% patients received 52.5 Gy in 23 fractions with 2.5 Gy/fraction, and 256 (59% patients received 66 Gy in 33 fractions with 2 Gy/fraction. Results The median follow-up time was 10.5 years. The 10-year LC rates were 91% and 87% for T1a and T1b respectively. Multivariate analysis showed LC rate was adversely affected by poorly differentiated histology (Hazard Ratio [HR]: 7.5, p = 0.035; involvement of anterior commissure (HR: 2.34, p = 0.011; fraction size of 2.0 Gy (HR: 2.17, p = 0.035 and tumor biologically effective dose (BED 15 (HR: 3.38, p = 0.017. Conclusions The negative impact of anterior commissure involvement could be overcome by delivering a higher tumor BED through using fraction size of > 2.0 Gy.

    From 1971 through 1982, 442 patients with laryngeal carcinoma were seen at the Leiden University Hospital. They were treated either with radiotherapy alone, sandwich therapy (pre- and postoperative radiotherapy) or by surgery followed by postoperative irradiation. Three hundred and sixty-six patients with glottic or supraglottic tumours could be analysed with respect to two different treatments, complications of treatment and some prognostic factors. Two endpoints of analysis were used: disease-free interval and survival to cfancer death. In patients with glottic or supraglottic carcinoma, the survival of patients with advanced disease, treated with radiotherapy only, was worse as compared to the survival of the same category of patients who were treated with sandwich therapy (p<0.005). In small supraglottic tumours, the survival with both therapy policies was equal. There was no influence on prognosis of histological differentiation of the tumour. It appeared that interruption of radiotherapy for more tah two days had an adverse effect on survival in patients with glottic carcinoma (p=0.0001). (author). 16 refs.; 4 figs.;

    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.

    An unblinded retrospective analysis of prospectively collected data was carried out on 138 patients affected by glottic pT2 and selected pT3 squamous cell carcinomas (SCC) treated by transoral laser microsurgery (TLM). The entire cohort was divided into two groups: Group A included 78 "high-risk" patients (pT2 with impaired vocal cord mobility, pT3 for anterior paraglottic and/or pre-epiglottic space invasion, presence of angioembolization, perineural spread, and positive lymph nodes in the neck) who underwent postoperative surveillance by endoscopy and imaging (CT or MR), while Group B included 60 "low-risk" patients (pT2 with absence of the above-mentioned features) who underwent endoscopic follow-up alone. Aim of the present study was to assess the diagnostic gain in performing combined endoscopic and radiologic surveillance in the "high-risk" group compared to endoscopy alone in the "low-risk" one. There was no significant difference in terms of overall and disease-specific survivals between the two follow-up policies in spite of their different risk profiles. The same was true for organ preservation rate, which was 81% in the "high-risk" and 89% in the "low-risk" group. In contrast, the cumulative probability of disease-free survival was 54% for Group A and 65% for Group B (p = 0.0023). Therefore, our combined endoscopy and imaging surveillance protocol allowed increasing the submucosal recurrence detection rate in "high-risk" pT2-pT3 glottic SCC to 43%. An earlier detection of submucosal recurrences made salvage surgery by TLM feasible in at least half of cases, thus closing the gap between oncologic outcomes obtained in "high-"- vs. "low-risk" patients and leading to organ preservation rates that are favorably comparable to those obtained with open-neck partial laryngectomies and non-surgical organ preservation protocols.

    Transoral laser microsurgery (TLM) represents one of the most effective treatment strategies for Tis-T2 glottic squamous cell carcinomas (SCC). The prognostic influence of close/positive margins is still debated, and the role of narrow band imaging (NBI) in their intraoperative definition is still to be validated on large cohort of patients. This study analyzed the influence of margin status on recurrence-free survival (RFS) and disease-specific survival (DSS). We retrospectively studied 507 cases of pTis-T1b (Group A) and 127 cases of pT2 (Group B) glottic SCC. We identified the following margin status: negative ( n  = 232), close superficial ( n  = 79), close deep (CD) ( n  = 35), positive single superficial ( n  = 146), positive multiple superficial ( n  = 94), and positive deep ( n  = 48) and analyzed their impact on RFS and DSS. Close margins were defined by tumor-margin distance <1 mm. Pre-TLM margins were defined by white light in 323 patients, whereas NBI was employed in 311 patients. In Group A, DSS and RFS were reduced in positive multiple superficial and positive deep margins (DSS = 96.1 and 97%, both p  < 0.05; RFS = 72%, p  < 0.001 and 75.8%, p  < 0.01). In Group B, DSS was reduced in positive multiple superficial margins (82.4%, p  < 0.05). RFS was reduced in positive single superficial, positive multiple superficial, and positive deep margins (62.5, 41.2, and 53.3%, p  < 0.01). In the entire population, RFS was reduced in CD margins (77.1%, p  < 0.05). Use of NBI led to improvement in RFS and DSS. The study indicates that close and positive single superficial margins do not affect DSS. By contrast, all types of margin positivity predict the occurrence of relapses, albeit with different likelihood, depending on stage/margin type. CD margins should be considered as a single risk factor. Use of NBI granted better intraoperative margins definition.

    Histological diagnosis of laryngeal epithelial abnormalities may range from mucosal aberration, without risk of progressing into invasive neoplasm, to in situ or invasive carcinoma. Precise identification of epithelial abnormalities of laryngeal mucosa requires biopsy and microscopic evaluation. Random biopsies are frequently inadequate, since they are not representative for the entire lesion. Excisional Biopsy, allowing removal of lesion together with a rim of healthy tissue is ideal for both diagnosis and treatment. If completely removed, the cancer should not require further treatment; if the margins are not free of disease, re-excision or radiotherapy is considered as alternative options. Laser excision represents an extension of the clinical application of endoscopy, allowing the laryngologist to perform an accurate and bloodless surgery. Endoscopic laser treatment for selected glottic SCC (squamous cell carcinoma) has been shown to provide an excellent alternative to radiotherapy or open neck surgery in terms of cure rate and functional results. Preliminary results are presented with the purpose of stressing the role of EB with CO2 laser in diagnosis and treatment of selected glottic carcinoma. (author). 16 refs

    2013-01-01

    Background Malignant tumours of minor salivary glands are uncommon, representing only 2-4% of all head and neck cancers. In the larynx, minor salivary gland tumours rarely occur and constitute less than 1% of laryngeal neoplasm. Most of the minor salivary gland tumours arise in the subglottis; however, they can also occur in the supraglottis, in the false vocal cords, aryepiglottic folds and caudal portion of the epiglottis. The most common type of malignant minor salivary gland tumour is adenoid cystic carcinoma. Methods We present a unusual case of adenoid cystic carcinoma of glottic-subglottic region in a 61-year-old woman. Follow-up endoscopy and laryngeal magnetic resonance imaging (MRI) at three years after treatment showed no recurrence of the tumour. Results The diagnosis of glottic-subglottic adenoid cystic carcinoma should be considered in patients who are characterized by dyspnea, cough and stridor, but do not respond to pharmacologic approach. Conclusions Adenoid cystic carcinoma is usually a very slow growing cancer, invested by an apparently normal laryngeal mucosa, so that it can show no clear symptoms for a long time. For these reasons the increasing number of diagnostic mistakes or late diagnosis that may be fatal in some cases. PMID:24427787

  10. Early Detection Of Cancer

    Full Text Available Farly detection of cancer is based upon three fundamental assumptions, firstly that the trea'ment of benign and precancerous lesions reduces the incidence of cancer, secondly, that the treatment of in situ cancers is conducive to total cure and thirdly that early diagnosis and management of invasive cancer ensures be.ter survival. When patient seeks medical advice for vague symptoms, which could however be due to a possible malignant tumour at a particular site, the alert clinician should investigate the patient immediately to exclude cancer. At this stage cancer is usually not significantly advanced. Currently the U. I. C. C. (International Union for Cancer Control} is studying the epidemiology of cancers in various countries The importance of this is two folds : Firstly by focussing attention on a section of population vulnerable to a particular cancer an early detection is facilitated Secondly by changing the causative factors responsible to a particular cancer, the incidence of that cancer can be reduced e. g. reduction in lung cancer following campaigns against ciguette smoking and reductioi in breast cancer after campaigns for advocating breast feeding of infants, lowering fat consumption and encouraging self palpation of breast regularly. Indeed early diagnosis of cancer implies diagnosis of cancer in almost a symptomatic stage It involves motiva’ion of the population towards acquisitio : of knowledge, attitude and practice.. Epidemiologies and clinicians should be able to recognise high risk cases exposed to particular neoplasia and knowledge of alarming symptoms should be pro- pogated for wide publicity through common available media and means. Probable cases should have regular clhrcal examination periodically and relevant investigations including radiological, imaging techniques and Bio-Chemical examination should be undertaken as and when desired Suspicious lesions should be investigated by specific tests including smear cytology

    The problem is that current definitions of early gastric cancer allow the inclusion of regional lymph node metastases. The increasing use of endoscopic submucosal dissection to treat early gastric cancer is a concern because regional lymph nodes are not addressed. The aim of the study was thus to critically evaluate current evidence with regard to tumour-specific factors associated with lymph node metastases in "early gastric cancer" to develop a more precise definition and improve clinical management. A systematic and comprehensive search of major reference databases (MEDLINE, EMBASE, PubMed and the Cochrane Library) was undertaken using a combination of text words "early gastric cancer", "lymph node metastasis", "factors", "endoscopy", "surgery", "lymphadenectomy" "mucosa", "submucosa", "lymphovascular invasion", "differentiated", "undifferentiated" and "ulcer". All available publications that described tumour-related factors associated with lymph node metastases in early gastric cancer were included. The initial search yielded 1494 studies, of which 42 studies were included in the final analysis. Over time, the definition of early gastric cancer has broadened and the indications for endoscopic treatment have widened. The mean frequency of lymph node metastases increased on the basis of depth of infiltration (mucosa 6% vs. submucosa 28%), presence of lymphovascular invasion (absence 9% vs. presence 53%), tumour differentiation (differentiated 13% vs. undifferentiated 34%) and macroscopic type (elevated 13% vs. flat 26%) and tumour diameter (≤2 cm 8% vs. >2 cm 25%). There is a need to re-examine the diagnosis and staging of early gastric cancer to ensure that patients with one or more identifiable risk factor for lymph node metastases are not denied appropriate chemotherapy and surgical resection.

    The objective of this study was to determine if chemoradiotherapy improves local control of T2 glottic squamous cell carcinoma. From 1989 to 2003, 61 patients with T2 glottic cancer were treated with radiation alone or radiation in conjunction with various chemotherapy agents. Overall survival and local control rates for all 61 patients were 83.6% and 82.0%, respectively at five years. The addition of chemotherapy offered no survival benefit or improvement in local control rates compared to radiotherapy alone. Extending treatment duration lowered local control rates, however, no survival-related prognostic factors were identified. No treatment-related late toxicity was observed. The addition of chemotherapy in patients with T2 glottic cancer treated with radiation does not improve outcomes. This validates the use of radiotherapy alone as the standard of care for patients with this disease. (author)

    The therapy of early breast cancer has been changing during the last decennium. It requires a multi-disciplinary approach and in each of these disciplines improvements have been implemented. The result is that treatment schedules can now be adapted to specific subgroups. In this review early breast cancer is defined as operable disease, using the criteria set out by Haagensen. Emphasis is given to describing the new developments in prognostic criteria, since these form the basis for creating subgroups for specific treatment schedules. Distinction is made between the factors relating to growth rate and those relating to metastatic potential. Data on screening promises a beneficial effect of the implementation of screening in national health care programs. Important shifts are seen in treatment schedules; the place of postoperative radiotherapy after classic ablative treatment is being challenged, whereas it plays a major role in the new breast conserving therapy schedules. The data mentioned in the review suggest that a large proportion of 'operable' cases can be treated with breast conservation but details in the technique of breast conserving therapy are still under investigation. They form a major part of the coming prospective studies in breast cancer. Improvements in reconstruction techniques, creating better cosmetic results, make reconstruction more competitive with breast conserving therapy. The use of chemotherapy and endocrine manipulation in early breast cancer has now been clearly confirmed by the overview technique by the Peto-group, thanks to all efforts of individual trialists together.

    Purpose: Local control probabilities of T1,2 glottic laryngeal cancer were evaluated in relation to dose and fractionation of radiation therapy (RT). Materials and methods: Between 1975 and 1993, 96 T1N0M0 glottic cancers and 32 T2N0M0 glottic cancers were treated with definitive RT. Total RT dose was 60-66 Gy/2 Gy for most of the T1 and T2 tumors, although 10 T2 tumors were treated with hyperfractionation (72-74.4 Gy/1.2 Gy bid). Of the 128 patients, 90 T1 glottic tumors and 30 T2 glottic tumors were followed for >2 years after treatment. Multivariate analyses using the Cox proportional hazards model and a logistic regression analysis were performed to evaluate the significance of prognostic variables on local control. Results: The 5-year local control probability for T1 tumors was 85%, whereas that for T2 tumors was 71%. Multivariate analyses demonstrated that only overall treatment time (OTT) was a significant variable for local control. Total RT dose, normalized total doses at a fraction size of 2 Gy, and fraction size were not significant. Local control probability of T1 tumors with an OTT of 42-49 days was significantly higher than that of tumors with an OTT of >49 days (P < 0.02). Only a 1-week interruption of RT, due to holidays, significantly reduced the 5-year local control probability of T1 glottic tumors from 89 to 74% (P < 0.05). Conclusions: These results indicate that OTT is a significant prognostic factor for local control of T1 glottic tumors

     CO 2 laser transoral microsurgery for glottic carcinoma, when indicated, has the well-established advantages of low morbidity and positive oncological outcomes. The present study aims to determine how patient age, and tumor site could negatively impact prognosis; other variables such as the status of the margins of resection, tobacco and alcohol intake, and the grade of differentiation of the tumors have been evaluated. This was a retrospective analysis on 261 patients with a glottic carcinoma who underwent CO 2 laser transoral microsurgery. The impact of different variables was calculated using univariate and multivariate analyses. The study included 248 males and 13 females. The median follow-up period was 4.3 years. Five-year disease-specific survival, recurrence-free survival, local control with laser alone, overall laryngeal preservation, and overall survival rates were 99.4, 92.2, 93.8, 97.6, and 85.5%, respectively. Equivalent results were observed in young and elderly patients. Patients with positive margins after CO 2 laser transoral microsurgery showed a reduced local control with laser alone. T2 patients with true subglottic spreading and patients with anterior commissure involvement of grade 3 (Rucci's classification) experienced worse local control rates, despite free surgical margins confirmed by histology.  CO 2 laser transoral microsurgery is an effective and reproducible single-stage modality therapy for young and elderly patients with glottic carcinoma. Superficial close margins can be managed by a careful wait-and-see policy, while positive margins should undergo surgical enlargement. In our experience, undifferentiated tumors, true subglottic extension, and anterior commissure involvement of grade 3 were associated with worse outcomes.

    Early-stage cancer detection could reduce breast cancer death rates significantly in the long-term. The most critical point for best prognosis is to identify early-stage cancer cells. Investigators have studied many breast diagnostic approaches, including mammography, magnetic resonance imaging, ultrasound, computerized tomography, positron emission tomography and biopsy. However, these techniques have some limitations such as being expensive, time consuming and not suitable for young women. Developing a high-sensitive and rapid early-stage breast cancer diagnostic method is urgent. In recent years, investigators have paid their attention in the development of biosensors to detect breast cancer using different biomarkers. Apart from biosensors and biomarkers, microwave imaging techniques have also been intensely studied as a promising diagnostic tool for rapid and cost-effective early-stage breast cancer detection. This paper aims to provide an overview on recent important achievements in breast screening methods (particularly on microwave imaging) and breast biomarkers along with biosensors for rapidly diagnosing breast cancer.

    Full Text Available Vast numbers of studies and developments in the nanotechnology area have been conducted and many nanomaterials have been utilized to detect cancers at early stages. Nanomaterials have unique physical, optical and electrical properties that have proven to be very useful in sensing. Quantum dots, gold nanoparticles, magnetic nanoparticles, carbon nanotubes, gold nanowires and many other materials have been developed over the years, alongside the discovery of a wide range of biomarkers to lower the detection limit of cancer biomarkers. Proteins, antibody fragments, DNA fragments, and RNA fragments are the base of cancer biomarkers and have been used as targets in cancer detection and monitoring. It is highly anticipated that in the near future, we might be able to detect cancer at a very early stage, providing a much higher chance of treatment.

    1996-01-01

    Purpose: To evaluate the influence of fraction size and overall time on local control of T1 and T2 glottic carcinoma Methods and Materials: Between 1956 and 1995, 318 consecutive patients with early glottic carcinoma (250 T1, 68 T2) were treated with definitive megavoltage radiotherapy at UCSF. Treatment was delivered using conventional fractionation at one fraction/day, 5 days/week. Minimum tumor dose ranged from 50 to 81Gy (median: 61Gy). The fraction size was 200cGy. Conclusions: Risk of tumor recurrence increased with higher T-stage, smaller fraction size, and longer overall time. Our results suggest that for optimal local control, radiotherapy for early glottic carcinoma should be completed as soon as possible, preferably within 6 weeks, using a fraction size ≥ 225cGy. Our current policy is to treat T1 and T2 vocal cord carcinomas with 225cGy/fraction/day, 5 days/week to a total dose of 63-65Gy

    Full Text Available Background and Aims: Oropharyngeal colonisation followed by aspiration of contaminated secretions is the major cause for ventilator-associated pneumonia (VAP. Pooled secretions present in the sub-glottic area above inflated endotracheal tube cuff may be aspirated into the lower airways. It was hypothesised that intermittent suctioning of sub-glottic secretions would prevent VAP. Methods: Group I (n = 50 patients were intubated with HiLo Evac™ endotracheal (ET tube with facility for sub-glottic suctioning, and Group II (n = 50 patients were intubated with HiLo Contour™ ET tube without such facility. In the Group I, sub-glottic suctioning was performed every 2 h. Incidence of VAP, mean ventilator days, Intensive Care Unit (ICU stay and mortality were compared. Qualitative variables were reported as percentages and were compared by Chi-square test or unpaired two-tailed, Fisher′s exact test, as appropriate, to analyse the significance of difference between the two groups. Results: The two groups were similar with respect to demographic characteristics. VAP was seen in 6% of patients in Group I and 22% of patients in Group II (P = 0.021. Both early- and late-onset VAPs were significantly reduced in Group I.

    1988-01-01

    The incidence of colorectal cancer has been gradually increasing in Japan, and if the present rate of increase is maintained it has been estimated that it will become the most common of all malignant neoplasms by the year 2000. It has been proved that colorectal cancer can be completely cured, if it is treated in its early phase. Early cancer of the large bowel is defined as a cancer which is limited to the mucosal membrane or submucosal layer, regardless of lymph node and distant metastases. Detection of early cancer improves the overall curability of colorectal cancer. The greatest number of early cancers of the large bowel are polypoid lesions in their macroscopic form, and depressed lesions are rarely encountered. Accordingly, the first step in the detection of early cancer starts with the screening of polypoid lesion by radiology and endoscopy. This paper is concerned with diagnostic accuracy of radiology in the screening of colorectal cancer with endoscopic correlation

    A new one-stage approach for treatment of selected anterior glottic web has been successful. This case report illustrates its simplicity in microlaryngoscopy with complete lysis of the anterior glottic web by CO(2) laser. Then a small neck horizontal incision is made at the level of anterior commissure to gain exposure to thyroid cartilage. Absorbable suture is passed through the midline of thyroid cartilage below and above the anterior commissure. A knot is tied over thyroid ala. The suture acts as a tiny stent to prevent recurrence of the web. Copyright © 2012 The Voice Foundation. Published by Mosby, Inc. All rights reserved.

    A total of 110 patients with laryngeal cancer treated by radiotherapy during a period of 19 years between 1967 and 1985 were analyzed. Results were as follows; 1) Eighty-three patients (80 %) were irradiated curatively with doses given more than 40 Gy and 21 patients (20 %) were treated by postoperative irradiation. The mean age was 67.4 and the ratio of men to women was 8.1 : 1. 2) According to the primary site of laryngeal cancer undergoing a curative irradiation, glottic cancer was 70 % (58 patients), supraglottic cancer was 29 % (24 patients) and subglottic cancer was 1 % (1 patient). As for the stage classification, 22 patients was in stage I, 26 patients in stage II, 20 patients in stage III and 15 patients in stage IV. The rate of early stages (stages I and II) was 72 % in glottic cancer, but that of advanced stages (stages III and IV) was 79 % in supraglottic cancer. 3) The five-year survival rate of 21 patients who had treated by postoperative irradiation was 37 %, and that of 58 patients undergoing a curative irradiation was 32 %. The five-year survival rate of curatively irradiated patients with glottic cancer was 84 % in stage I, 48 % in stage II and 17 % in stage III and IV. In all of 21 patients with supraglottic cancer, the five-year survival rate was 15 %. 4) Eighteen patients survived more than 5 years ; 3 patients were postoperative irradiation and 15 were curative irradiation. In the curative irradiation, 12 patients were glottic cancer, and 3 were supraglottic cancer. (author)

  13. The radiology of early esophageal cancer

    Uematsu, S.

    1988-01-01

    The radiographic diagnosis of early esophageal cancer is described based on 25 cases in which depth of invasion was limited to not more than the submucosal layer. It is emphasized that double contrast radiography should be designed to delineate the subtle abnormalities of the esophageal mucosa and margins of lesions which are characteristic of early cancer, and that further investigation should be directed to improving the method of examination so that the detection of ep- and mm-cancer which has a better prognosis than sm cancer can be detected more readily. A macroscopic classification of early esophageal cancer (elevated, flat, depressed and mixed type) which is useful for both endoscopic and radiographic diagnosis is proposed. The 5-year survival rate of esophageal cancer which was limited to the submucosal layer or less (ep-, mm- and sm-cancer) was 50%

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

    Accumulating data suggest that metastatic dissemination often occurs early during tumour formation but the mechanisms of early metastatic spread have not yet been addressed. Here, we studied metastasis in a HER2-driven mouse breast cancer model and found that progesterone-induced signalling triggered migration of cancer cells from early lesions shortly after HER2 activation, but promoted proliferation in advanced primary tumour cells. The switch from migration to proliferation was regulated by elevated HER2 expression and increased tumour cell density involving miRNA-mediated progesterone receptor (PGR) down-regulation and was reversible. Cells from early, low-density lesions displayed more stemness features than cells from dense, advanced tumours, migrated more and founded more metastases. Strikingly, we found that at least 80% of metastases were derived from early disseminated cancer cells (DCC). Karyotypic and phenotypic analysis of human disseminated cancer cells and primary tumours corroborated the relevance of these findings for human metastatic dissemination. PMID:27974799

    Problems concerning diagnosis of early stomach cancer using X-ray and endoscopic investigation techniques are stated. Classification of early stomach cancer suggested by the Japan Endoscopy Society and division system of early stomach cancer into two main foms: depth (erosive-ulcerous) one and elevated (polypoid) one-is presented X-ray and endoscopic investigation techniques are shown to be high efficiency concerning revealingation of stomach mucous variations using biopsy, which allow to determine for certain whother the process is benign or malignant one

    Some potentialities of the X-ray and endoscopic methods in the recognition of early stomach cancer are analysed. Both methods are provided by a roentgenotogist. Of 396 operated patients with stomach cancer, early forms were detected in 78 which is equal to 8% of the detected number and 19.7% of the operated cancer pasients. Two macroscopic forms of early cancer were detected: cancer with ulceration (erosion-ulcerative form) and polypoidcancer. The first form is interpreted as primary-ulcerative cancer, malignant ulcers and cancer in the form of erosions, the second one as polyps, polypoid and patchlike cancer, malignant polyps. X-ray changes were detected in 80% of the patients, in the rest of 20% by the endoscopic method only. With the help of the roentgenological and endoscopic methods (without cytological examination) one cannot be sure of accurate differential diagnosis between malignant and benign variants of ulcerations and polypoid changes in early cancer. The potentialities of the X-ray method ir the detection of ulcerative and polypoid changes of the stomach make it possible to improve it, though under a strict condition of performing subsequent obligatory endoscopy and getting tissue specimens for biopsy. The organization of the common roentgenoendoscopic centers is found appropriate

    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.

    Full Text Available Total mesorectal excision is the “golden standard” of surgical treatment for rectal cancer. Development of endoscopic technologies allowed to implement the benefits of minimally invasive surgery in early rectal cancer treatment, decrease morbidity and mortality, improve functional outcome and quality of life. Oncological safety of this method is still a subject for discussion due to lack of lymph node harvest. Endoscopic operations for early rectal cancer are being actively implemented in daily practice, but lack of experience does not allow to include this method in national clinical prac-tice guidelines.

    Full Text Available Michael Untch1, Christian Jackisch21Interdisciplinary Breast Centre, Helios Klinikum Berlin-Buch, University Charité, Berlin, Germany; 2Department of Gynecology/Obstetrics, Klinikum Offenbach GmbH, Offenbach, GermanyAbstract: The adjuvant treatment of women with endocrine-sensitive early breast cancer has been dominated for the last 40 years by tamoxifen. However, the side-effects associated with this therapy have prompted a search for safer and biochemically more selective endocrine agents and led to the development of the third-generation aromatase inhibitors (AIs anastrozole, letrozole and exemestane. Promising results in advanced disease have paved the way for treating early breast cancer, and AIs are increasingly replacing tamoxifen in the adjuvant setting. Several large, randomized trials with AIs have been completed or are ongoing in women with early-stage breast cancer, documenting the significant impact that these drugs are making on the risk for recurrence of breast cancer. As a result, there is increasing and widespread use of AI therapy for the treatment of early-stage endocrine-responsive breast cancer. This review summarizes the data for exemestane in the adjuvant setting, showing that a switch to exemestane after 2 to 3 years of tamoxifen therapy is associated with a statistically significant survival benefit and is regarded as being sensitive by international and national experts.Keywords: early breast cancer, adjuvant setting, endocrine-sensitive, tamoxifen, aromatase inhibitor, exemestane, switch, IES 31, NSABP B-33, TEAM

    The barium enema has been a neglected tool in the diagnosis of early colon cancer. With appropriate attention to technical detail, the double contrast enema is capable of detecting the smallest malignant and pre-malignant lesions. Many of these early colon cancers are found in asymptomatic patients and these lesions are curable. The goal of a screening program should be to identify by history or by fecal occult blood testing patients at high risk for the development of colon cancer. These patients should be examined by high-quality double contrast enema in the search for these potentially lethal but curable lesions. In addition, we believe that any patient undergoing radiologic examination of the colon for whatever reason, should receive an examination of adequate quality to rule out an early colon cancer.

    2016-01-01

    Bisphosphonates have been studied in randomised trials in early breast cancer to investigate their ability to prevent cancer treatment-induced bone loss (CTIBL) and reduce the risk of disease recurrence and metastasis. Treatment benefits have been reported but bisphosphonates do not currently have...... regulatory approval for either of these potential indications. This consensus paper provides a review of the evidence and offers guidance to breast cancer clinicians on the use of bisphosphonates in early breast cancer. Using the nominal group methodology for consensus, a systematic review of the literature...... was augmented by a workshop held in October 2014 for breast cancer and bone specialists to present and debate the available pre-clinical and clinical evidence for the use of adjuvant bisphosphonates.

    Sputum cytology examination is the most effective method to detect early stage central type squamous cell carcinoma. As sputum-positive early stage lung cancer usually does not show any abnormal findings on chest X-ray film, fiberoptic bronchoscopy is subsequently performed for localization. However, sometimes cases do not show any abnormal findings of cancer endoscopically because they are very early stage cases. For the purpose of localization of invisible lesions the photodynamic reaction was employed in this study. Photodynamic reaction is achieved by transfer of energy of an excited photo-sensitizer induced by photoradiation of light. This phenomenon was already recognized in the beginning of this century. Study of tumor localization of the bronchial tree using hematoporphyrin derivative (HpD) and a mercury arc lamp was first performed in the Mayo Clinic in 1960s. In 1978, krypton laser was used first as a light source by Profio and Doiron. Authors have been doing research on early localization of such endoscopically occult early lung cancer since 1978. They recently developed an image processing system using an excimer dye laser for early localization of lung cancer. (author). 5 refs., 4 figs., 1 tab

    BACKGROUND: The optimal treatment for early prostate cancer has yet to be established. A well-tolerated hormonal therapy such as bicalutamide could be a useful treatment option in this setting, either as adjuvant or immediate therapy. A major collaborative clinical trials program was set up...... to investigate bicalutamide as a treatment option for local prostate cancer (localized or locally advanced disease). METHODS: The bicalutamide Early Prostate Cancer program comprises three randomized, double-blind, placebo-controlled trials of similar design that are being conducted in distinct geographical...... areas (North America; Australia, Europe, Israel, South Africa and Mexico; and Scandinavia). Men with T1b-4N0-1M0 (TNM 1997) prostate cancer have been randomized on a 1:1 basis to receive bicalutamide 150 mg daily or placebo. Recruitment to the program closed in July 1998, and follow-up is ongoing. Study...

    Use of brachytherapy with radioactive seeds in the management of early prostate cancer is commonly used in the United States. The early experience has been reported from the prostate treatment centers in Seattle for the last 10 years. In this manuscript we are reporting our early experience of 150 radioactive seed implantations in early stage prostate cancer using either Iodine 125 or Palladium 103 seeds. The average age of the patient is 66 years and the median Gleason score is 5.4 with a median PSA of 6. A brief description of the evolution of the treatment of prostate cancer as well as the preparation for the seed implantation using the volume study with ultrasound of the prostate, pubic arch study using CT scan of the pelvis and the complete planning using the treatment planning computers are discussed. We also have described the current technique which is used in our experience based on the Seattle guidelines. We plan a follow-up report with the results of the studies with longer follow-up.

    Abstract Pancreatic cancer (PC) is estimated to become the second leading cause of cancer death in the United States by 2020. Early detection is the key to improving survival in PC. Addressing this urgent need, the Kenner Family Research Fund conducted the inaugural Early Detection of Sporadic Pancreatic Cancer Summit Conference in 2014 in conjunction with the 45th Anniversary Meeting of the American Pancreatic Association and Japan Pancreas Society. This seminal convening of international representatives from science, practice, and clinical research was designed to facilitate challenging interdisciplinary conversations to generate innovative ideas leading to the creation of a defined collaborative strategic pathway for the future of the field. An in-depth summary of current efforts in the field, analysis of gaps in specific areas of expertise, and challenges that exist in early detection is presented within distinct areas of inquiry: Case for Early Detection: Definitions, Detection, Survival, and Challenges; Biomarkers for Early Detection; Imaging; and Collaborative Studies. In addition, an overview of efforts in familial PC is presented in an addendum to this article. It is clear from the summit deliberations that only strategically designed collaboration among investigators, institutions, and funders will lead to significant progress in early detection of sporadic PC.

    Full Text Available Abstract Background Current imaging techniques provide only limited information pertaining to the extent of infiltration of laryngeal carcinomas into vocal fold tissue layers. Therefore, it is needed to seek the contribute to the body of knowledge surrounding examination and characterization in laryngeal carcinoma infiltration. Methods Excised larynges were collected from 30 male laryngectomy patients with an average age of 43.5 years (ranging 36 to 55 years and history of smoking (≥10 years exhibiting T1, T2, or subglottal (normal vocal fold carcinomas. Vocal folds were preserved via freezing or immersion in paraffin. The depth of the mucosa, submucosa, and muscular layers in both normal vocal folds and tumor tissues of afflicted vocal folds was measured. Results The average depths of the mucosa, submucosa, and muscular layers in normal vocal folds were 0.15 ± 0.06 mm, 2.30 ± 0.59 mm, and 2.87 ± 0.88 mm, respectively. Infiltration measurements of T1 tumors showed a depth of 1.62 ± 0.51 mm and 1.32 ± 0.49 mm in frozen sections and paraffin-embedded samples, respectively. Similarly, T2 tumors showed a depth of 2.87 ± 0.68 mm and 2.58 ± 0.67 mm in frozen sections and paraffin-embedded samples, respectively. T1 and T2 tumors occupied 24.8 ± 10 and 48.5 ± 15 percent of the normal vocal fold depth, respectively. Conclusion This data provides a baseline for estimating infiltration of laryngeal carcinomas in vocal fold tissue layers, of particular interest to surgeons. This information may be used to assess typical depths of infiltration, thus allowing for more appropriate selection of surgical procedures based on individual patient assessment.

    Purpose: To report the treatment outcomes of definitive radiotherapy (RT) for early-stage squamous cell carcinoma (SCCA) of the glottic larynx. Methods and Materials: We retrospectively reviewed the medical records of 585 patients with T1N0 to T2N0 invasive SCCA of the glottic larynx treated between 1964 and 2006 with RT alone. All patients had at least 2 years of follow-up, had histologic diagnosis of invasive SCCA, and received continuous-course RT. None of these patients received chemotherapy or had elective nodal RT. The probabilities of local control (LC), ultimate LC, ultimate LC with larynx preservation, neck control, cause-specific survival (CSS), and overall survival (OS) were calculated by the Kaplan-Meier product-limit method. Results: The median follow-up for survivors was 12 years. Five-year LC rates were as follows: T1A, 94%; T1B, 93%; T2A, 80%; and T2B, 70%. Multivariate analysis revealed that overall treatment time greater than 41 days (p = 0.001) and poorly differentiated histology (p = 0.016) adversely affected LC. Five-year rates of ultimate LC with laryngeal preservation were: T1A, 95%; T1B, 94%, T2A, 81%; and T2B, 74%. Twenty-four (4%) of 585 patients failed in the neck; only 7 neck failures (1%) were isolated. Five-year CSS and OS rates were as follows: T1A, 97% and 82%; T1B, 99% and 83%; T2A, 94% and 76%; and T2B, 90% and 78%, respectively. Ten (1.7%) patients had severe and/or fatal complications. One patient died of a radiation-induced carotid artery angiosarcoma. Conclusion: Based on our study results, RT cures a high proportion of patients with T1N0 to T2N0 glottic SCCAs and has a low rate of severe complications.

    1988-01-01

    A literature review of 10 series using electrocoagulation, fulguration, or local excision demonstrates that about 70% of all patients had tumors smaller than 3 cm and the remainder had tumors measuring between 4 cm and 7 cm. Although primary tumor size in rectal cancer has little prognostic value per se, it is obviously important when determining the appropriateness of local therapy. Selecting patients for local therapy based on tumor size alone seems reasonable, since the recurrence and survival rates for the patients are similar to those achieved with radical surgery. Since patients treated with local excision alone have predominantly T1 or T2 tumors, a comparison with the data of others illustrates the prognostic utility of the degree of bowel penetration and shows five-year survival rates of 71% to 76% for patients with limited disease. In this chapter, the author describes an additional group of patients who also did well following postoperative radiotherapy after conservative surgical treatment

    Various radiotherapy planning methods for T1N0 laryngeal cancer have been proposed to decrease normal tissue toxicity. We compare helical tomotherapy (HT), linac-based intensity-modulated radiation therapy (IMRT), volumetric-modulated arc therapy (VMAT), and 3-D conformal radiotherapy (3D-CRT) techniques for T1N0 laryngeal cancer. Overall, 10 patients with T1N0 laryngeal cancer were selected and evaluated. Furthermore, 10 radiotherapy treatment plans have been created for all 10 patients, including HT, IMRT, VMAT, and 3D-CRT. IMRT, VMAT, and HT plans vs 3D-CRT plans consistently provided superior planning target volume (PTV) coverage. Similar target coverage was observed between the 3 IMRT modalities. Compared with 3D-CRT, IMRT, HT, and VMAT significantly reduced the mean dose to the carotid arteries. VMAT resulted in the lowest mean dose to the submandibular and thyroid glands. Compared with 3D-CRT, IMRT, HT, and VMAT significantly increased the maximum dose to the spinal cord It was observed that the 3 IMRT modalities studied showed superior target coverage with less variation between each plan in comparison with 3D-CRT. The 3D-CRT plans performed better at the D max of the spinal cord. Clinical investigation is warranted to determine if these treatment approaches would translate into a reduction in radiation therapy–induced toxicities.

    Full Text Available Breast cancer metastases to the stomach are very rare. As characteristics of breast cancer metastases to the stomach, metastases of lobular carcinoma, mainly with signet ring cells, are frequently observed, and they are often difficult to distinguish from a primary gastric cancer with signet ring cells. Moreover, because no characteristic symptoms are shown and they involve a submucosal lesion, it is difficult to make a radiographic diagnosis. However, if a gastric lesion is observed after breast carcinoma surgery, differentiation between a gastric primary lesion and a metastatic lesion is very important in order to determine treatment. We encountered a case that was diagnosed as early gastric cancer discovered using an endoscope 2 years after surgery and which was found to be breast cancer metastasis to the stomach by gross cystic disease fluid protein (GCDFP and cytokeratin (CK 7/20 immunostaining of the biopsy tissue. Here, we report our findings of this unique case.

    Abstract Innovation leading to significant advances in research and subsequent translation to clinical practice is urgently necessary in early detection of sporadic pancreatic cancer. Addressing this need, the Early Detection of Sporadic Pancreatic Cancer Summit Conference was conducted by Kenner Family Research Fund in conjunction with the 2014 American Pancreatic Association and Japan Pancreas Society Meeting. International interdisciplinary scientific representatives engaged in strategic facilitated conversations based on distinct areas of inquiry: Case for Early Detection: Definitions, Detection, Survival, and Challenges; Biomarkers for Early Detection; Imaging; and Collaborative Studies. Ideas generated from the summit have led to the development of a Strategic Map for Innovation built upon 3 components: formation of an international collaborative effort, design of an actionable strategic plan, and implementation of operational standards, research priorities, and first-phase initiatives. Through invested and committed efforts of leading researchers and institutions, philanthropic partners, government agencies, and supportive business entities, this endeavor will change the future of the field and consequently the survival rate of those diagnosed with pancreatic cancer.

    2016-03-01

    Esophageal cancer is one of the fastest rising forms of cancer in the Western world. Using High-Definition (HD) endoscopy, gastroenterology experts can identify esophageal cancer at an early stage. Recent research shows that early cancer can be found using a state-of-the-art computer-aided detection (CADe) system based on analyzing static HD endoscopic images. Our research aims at extending this system by applying Random Forest (RF) classification, which introduces a confidence measure for detected cancer regions. To visualize this data, we propose a novel automated annotation system, employing the unique characteristics of the previous confidence measure. This approach allows reliable modeling of multi-expert knowledge and provides essential data for real-time video processing, to enable future use of the system in a clinical setting. The performance of the CADe system is evaluated on a 39-patient dataset, containing 100 images annotated by 5 expert gastroenterologists. The proposed system reaches a precision of 75% and recall of 90%, thereby improving the state-of-the-art results by 11 and 6 percentage points, respectively.

    To review the history, current status, and future trends related to breast cancer screening. Peer-reviewed articles, web sites, and textbooks. Breast cancer remains a complex, heterogeneous disease. Serial screening with mammography is the most effective method to detect early stage disease and decrease mortality. Although politics and economics may inhibit organized mammography screening programs in many countries, the judicious use of proficient clinical and self-breast examination can also identify small tumors leading to reduced morbidity. Oncology nurses have exciting opportunities to lead, facilitate, and advocate for delivery of high-quality screening services targeting individuals and communities. A practical approach is needed to translate the complexities and controversies surrounding breast cancer screening into improved care outcomes. Copyright © 2017 Elsevier Inc. All rights reserved.

    A prospective evaluation of vocal changes in patients receiving radiation therapy for T1 and T2 (AJC) glottic carcinoma was undertaken in January 1987. Vocal analysis was performed prior to radiotherapy and at specific intervals throughout the radiation treatment program. The voicing ratio was extrapolated from a sustained vowel phonation using the Visipitch interfaced with the IBM-PC. Preliminary observations suggested three distinct patterns of vocal behavior: 1. reduced voicing ratio with precipitous improvement within the course of treatment, 2. high initial voicing ratio with reduction secondary to radiation induced edema, with rapid improvement in the voicing component after the edema subsided, and 3. fluctuating voicing ratio during and following treatment. Enrollment of new patients and a 2-year follow-up of current patients was undertaken

    Computer image processing was used to enhance gastric lesions in order to improve the detection of stomach cancer. Digitization was performed in 25 cases of early gastric cancer that had been confirmed surgically and pathologically. The image processing consisted of grey scale transformation, edge enhancement (Sobel operator), and high-pass filtering (unsharp masking). Grey scale transformation improved image quality for the detection of gastric lesions. The Sobel operator enhanced linear and curved margins, and consequently, suppressed the rest. High-pass filtering with unsharp masking was superior to visualization of the texture pattern on the mucosa. Eight of 10 small lesions (less than 2.0 cm) were successfully demonstrated. However, the detection of two lesions in the antrum, was difficult even with the aid of image enhancement. In the other 15 lesions (more than 2.0 cm), the tumor surface pattern and margin between the tumor and non-pathological mucosa were clearly visualized. Image processing was considered to contribute to the detection of small early gastric cancer lesions by enhancing the pathological lesions. (author)

Survival rates, failure patterns, complication rates and degrees of severity were analyzed according to several factors. Results : Overall 5 year survival rate and relapse free survival rate were 72.3%, and 72.8% respectively. Prognostic factors were stage, size, pathology, RT response and there was no significant survival difference among the reasons of radiotherapy choice. There were 19 cases of treatment failure, another 3 cases were not tumor related death, and most of treatment related failure occurred within 24 months. Late complication rate of bladder and rectum were 8.8%, 15% respectively, frequency and severity of complication were correlated with ICR fractionation dose and total dose. Conclusion : These results showed that survival rates of early stage radiation treated cervix cancer patients were comparable to surgical series, but more aggressive treatment methods needed for stage IIA poor prognostic patients, To decrease late complication, choice of proper ICR dose and meticulous vaginal packing is needed

    Full Text Available OBJECTIVE: The therapeutic effect of middle frontal horizontal partial laryngectomy (MFHPL in treating stage T1b squamous cell carcinoma of the glottic larynx involving anterior vocal commissure (AVC was compared with that of the anterior frontolateral vertical partial laryngectomy (AFVPL. The feasibility and practical significance of MFHPL in clinical application was discussed in the present study. METHODS: From January 1996 to January 2010, a total of 65 patients diagnosed with stage T1bN0M0 glottic laryngeal cancer were treated with MFHPL or AFVPL. The postoperative complications, glottic reconstruction, recurrence rate, voice quality and survival rates were evaluated and compared between two treatments. RESULTS: AFVPL and MFHPL were performed in 34 and 31 patients, respectively. Flexible fiberoptic laryngoscopy revealed that in the MFHPL-treated patients the reconstructed glottis was spacious and symmetric. In contrast, AFVPL treatment resulted in irregular glottic area with poor symmetry and tubular glottis. The incidence of postoperative laryngeal stenosis significantly differed between the MFHPL- and AFVPL-treated groups (P = 0.025. No significant difference was detected in the 3- and 5-year overall- or tumor-free survival rates between two treatments. The Voice Handicap Index (VHI and maximum phonation time (MPT after surgery were 51.0±12.99 and 12.42±3.44 sec in the AFVPL-treated group; while in the MFHPL-treated patients they were 31.81±7.48 and 7.65±1.98 sec, respectively. Both differences in VHI (P = 0.012 and MPT (P = 0.024 were significant between two treatments. CONCLUSIONS: MFHPL was comparable to AFVPL with respect to postoperative complications, recurrence rate and survival rates, but possessed advantages over AFVPL in terms of the incidence of laryngeal stenosis and voice quality. Our study indicated that MFHPL has a potential value in clinical practice of treating stage T1b squamous cell carcinoma of the

    The treatment of oral cancer requires an effective rehabilitation strategy such as an early intensive rehabilitation (EIR) program. The medical records and data of 41 patients who participated in an EIR program and 20 control group patients were analyzed. These patients all underwent surgical resection of the primary tumor followed by microsurgical reconstruction using free flaps. The length of stay (LOS) at the acute care hospital was compared between the two groups. Four indexes were used to evaluate the effectiveness of the EIR program. EIR patients stayed an average of 11.6 fewer days at the acute care hospital. All indexes showed significant improvements (p < 0.001). The Barthel Index (BI) and the Early Intensive Rehabilitation Barthel Index (EIR-BI) improved by 36.0 and 103.6 points, respectively. At discharge, the Bogenhausener Dysphagia Score (BODS) had improved to a score of 11.0 compared to the 13.9 at admission. EIR patients had a Work Ability Index (WAI) score of 25.7. Length of stay at the acute care hospital can be reduced using early intensive rehabilitation if patients are transferred to an intensive rehabilitation clinic early.

    Esteva, Francisco J; Hortobagyi, Gabriel N

    2004-01-01

    A multitude of molecules involved in breast cancer biology have been studied as potential prognostic markers. In the present review we discuss the role of established molecular markers, as well as potential applications of emerging new technologies. Those molecules used routinely to make treatment decisions in patients with early-stage breast cancer include markers of proliferation (e.g. Ki-67), hormone receptors, and the human epidermal growth factor receptor 2. Tumor markers shown to have prognostic value but not used routinely include cyclin D 1 and cyclin E, urokinase-like plasminogen activator/plasminogen activator inhibitor, and cathepsin D. The level of evidence for other molecular markers is lower, in part because most studies were retrospective and not adequately powered, making their findings unsuitable for choosing treatments for individual patients. Gene microarrays have been successfuly used to classify breast cancers into subtypes with specific gene expression profiles and to evaluate prognosis. RT-PCR has also been used to evaluate expression of multiple genes in archival tissue. Proteomics technologies are in development

    Currently, early colorectal cancer (ECC) constitutes only 10% of the total of diagnosed colorectal malignancy. This proportion is expected to show an important increase with the different screening protocols that are on the way, together with recent advances in diagnostic and therapeutic colonoscopy. We compare the histopathologic spectrum of ECC from the western and Japanese viewpoint, defining the anatomopathologic characteristics of this lesions, together with the natural history and new classification and staging systems; variables which are all oriented to establish the grade of local invasion and risk of nodal spread. The knowledge and integral analysis of the different biologic, clinical, histological and endoscopic characteristics of ECC, will determine the most rational individual therapeutic pathway from the prognostic point of view

    Decision about the administration of adjuvant therapy for early breast cancer depends on the evaluation of prognostic factors. Lymph node status, tumor size and grade of differentiation are classical variables in this regard, and can be complemented by hormonal receptor status and HER2 expression. These factors can be combined into prognostic indexes to better estimate the risk of relapse or death. Other factors are less important. Gene profiles have emerged in recent years to identify low-risk patients who can forgo adjuvant chemotherapy. A number of profiles are available and can be used in selected cases. In the future, gene profiling will be used to select patients for treatment with new targeted therapies. Copyright © 2015 Elsevier España, S.L.U. All rights reserved.

  20. Imaging in early phase childhood cancer trials

    Adamson, Peter C.

    2009-01-01

    Advances made in the treatment of childhood malignancies during the last four decades have resulted in overall cure rates of approximately 80%, but progress has slowed significantly during the last 10 years, underscoring the need for more effective and less toxic agents. Current research is focused on development of molecularly targeted agents, an era ushered in with the discovery of imatinib mesylate for the treatment of chronic myelogenous leukemia. Since imatinib's introduction into the clinic, an increasing number of tyrosine kinase inhibitors have been developed and entered into clinical trials and practice. Parallel to the initial advances made in molecularly targeted agents has been the development of a spectrum of novel imaging modalities. Future goals for imaging in childhood cancer research thus include (1) patient identification based on target identification or other biologic characteristics of the tumor, (2) assessing pharmacokinetic-pharmacodynamic (PK-PD) effects, and (3) predictive value with an early indication of patient benefit. Development and application of novel imaging modalities for children with cancer can serve to streamline development of molecularly targeted agents. (orig.)

    This paper describes the present state of radiotherapy (RT) of early stage cervical cancer involving the history, outcomes of clinical trials, procedure for each stage, irradiation methods, concurrent chemo-RT (CCRT), late adverse events, and QOL after RT. It has a history of >100 years from the brachytherapy with radium, but is not yet completely established even now. There are many RT trials hitherto. Retrospectively, no significant difference is seen in outcomes of radical RT and surgery: 80-90% efficacy for stage I and 60-80% for II in the former, respectively, and 80-96% and 65-80%, in the latter. Between RT and surgery, there is a report of randomized comparative study in Italy. In Japan, reported are comparative outcomes based on patients' choice for therapy, retrospective studies including authors' one, prospective multi-institutional cooperative trials by Japanese Radiation Oncology Study Group, and Treatment Guidelines for Cervical Cancer (2007). RT procedure depends on the stage defined by FIGO (International Federation of Gynecology and Obstetrics) and at stages I-II, intracavitary RT is major with optimal dose 29 Gy/5 fractions for I, and 23/4 Gy with external total pelvic radiation 50 Gy for II. In external radiation, the planning target volume includes the whole pelvic field with 1.8-2 Gy/5 weeks and optionally, the extended field when metastasis suspicious. Intracavitary RT with application device in the uterine is of significance for the cancer as 50% complete cure even in stage III is reported. CCRT brings about good prognosis, which is shown in a Japanese trial to compare postoperative RT alone and CCRT with CDDP and 5-FU. The late adverse events are seen mainly in the large bowel and studies of QOL, an important factor for choice of treatment, are now in progress. (T.T.)

    Childhood cancer survivors experience excessive weight gain early in treatment. Lifestyle interventions need to be initiated early in cancer care to prevent the early onset of obesity and cardiovascular disease (CVD). We reviewed the existing literature on early lifestyle interventions in childhood cancer survivors and consider implications for clinical care. Few lifestyle interventions focus on improving nutrition in childhood cancer survivors. A consistent effect on reducing obesity and CVD risk factors is not evident from the limited number of studies with heterogeneous intervention characteristics, although interventions with a longer duration and follow-up show more promising trends. Future lifestyle interventions should be of a longer duration and include a nutrition component. Interventions with a longer duration and follow-up are needed to assess the timing and sustainability of the intervention effect. Lifestyle interventions introduced early in cancer care are both safe and feasible.

    Background and purpose: The T-classification has shortcomings in the prediction of local outcome of glottic squamous cell carcinoma (SCC) treated by definitive radiation therapy. In this regard, the value of several CT-derived tumour parameters as predictors of local outcome was investigated. Materials and methods: The pretreatment CT studies of 119 patients with glottic SCC (T1, n=61; T2, n=40; T3, n=14; T4, n=4) treated with curative intent by radiation therapy were reviewed for tumoral involvement of specific laryngeal anatomic subsites (including laryngeal cartilages). Tumour volume was calculated with the summation-of-areas technique. Actuarial (life-table) statistical analysis was done for each of the covariates; multivariate analysis was performed using the Cox proportional hazards model.Results: In the actuarial analysis tumour volume was significantly correlated with local recurrence rate (P=0.0062). Involvement of the cricoid cartilage (P=0.0052), anterior commissure (P=0.0203), subglottis (P=0.0481) and preepiglottic space (P=0.0134) and degree of involvement of the true vocal cord (P=0.0441) and paraglottic space at the level of the true vocal cord (P=0.0002) were also significantly correlated with local recurrence rate. In the multivariate analysis, only degree of involvement of the paraglottic space (at the level of the true vocal cord) (P=0.0001) and preepiglottic space (P=0.02) were found to be independent predictors of local recurrence. The T-category was significantly correlated with local outcome in the actuarial analysis (P=0.0001), but not in the multivariate analysis (P=0.5915). Conclusions: Several CT-derived parameters are powerful predictors of local outcome in glottic cancer treated with radiation therapy; some of these parameters are stronger linked to the local control rate than the T-classification.

    With long-term follow-up, the DBCG 77B trial demonstrates that oral single-agent cyclophosphamide significantly reduces the risk of recurrence and mortality as compared with no systemic therapy in pre-menopausal patients with high-risk early breast cancer. DBCG 77B is the only randomised trial assessing single-agent cyclophosphamide; and a second comparison suggests that its benefits are comparable to what may be achieved by classic CMF. The lack of benefits from adding methotrexate and fluorouracil to cyclophosphamide paved the way for combining cyclophosphamide with anthracyclines and later taxanes. DBCG 89D showed an incremental benefit in DFS and OS from substituting methotrexate with epirubicin. The advantage of anthracycline-containing three-drug combinations over CMF was confirmed by others and in the individual-patient EBCTCG meta-analysis, while standard AC or EC for four cycles not was superior to classic CMF. A further reduction in breast cancer mortality appeared in the EBCTCG meta-analysis from the addition of a taxane to a standard AC, while the substitution of cycles or drugs with a taxane was not associated with a reduction in mortality. No apparent benefit was observed in an early analysis of the DBCG 82C evaluating the addition of CMF to tamoxifen in post-menopausal high-risk breast cancer patients. Apart from menopausal status, the two trials had identical selection criteria, and the differences in outcome warranted a long-term follow-up of the 82C trial. After ten years of follow-up, CMF in the DBCG 82C was associated with a significant improvement in DFS; but even with 24 years of follow-up, mortality was not significantly improved. The diversity in outcome from the 77C and the 82B trials triggered further studies. The 77B trial used classic CMF with oral cyclophospamide, while a four-weekly intravenous CMF regimen was used in the 82B and C trials, and a three-weekly CMF regimen was used in the succeeding 89B and D trials.

    Objective: To analyze clinico pathological presentation of tongue cancers and to calculate survival rates (SR) with disease free survival rates (DFSR) and recurrence rates (RR) in different treatment modalities and to compare the results of surgery alone and radiotherapy alone in stage I and stage II disease and to calculate better option of treatment in early tongue cancers. Design: A longitudinal study. Place and Duration of Study: Department of Otolaryngology and Head and Neck Surgery, Pakistan Institute of Medical Sciences, Islamabad (PIMS) from January 1987 to June 1998. Patients and Methods: Case histories of 67 patients were collected from departmental record. Clinical data included age at diagnosis, gender of patient, location of tumor, presenting symptoms and their duration, biopsy report, predominant histological pattern of tumor, nodal status, stage of tumor, treatment modality employed, tumor recurrence, metastasis and survival rates with disease-free survival rates after 2 years' follow-up. Results: Among 67 patients there were 31 males and 36 females. Mean age was 50 years (range 20 - 80 years). Sixty seven patients with primary cancer of tongue constituted 38.8% of oral cavity cancers during period of 1987 - 1998 in PIMS. Smoking, poor oro dental hygiene (POOH) and betel nuts chewing were the main risk factors. Odynophagia and painful ulcers on lateral border of tongue were the main clinical symptoms with average duration of 7 months. Regional lymph nodes were palpable in 32.8%, 5.5% was in stage I, 35.8% in stage II, 29.8% in stage III, and 28.3% was in stage IV. No patient was found to have distant metastasis. Histopathology in 94% of cases was squamous cell carcinoma (SCC). Recurrence and survival rates were determined in 49 patients. Average time of recurrence was 12.5 months. Recurrence was 100% loco regional (LR). It was 85.7% in patients treated with radiotherapy (RT) alone, 42.1% in patients treated with surgery alone and 31.2% in patients

    During the two year period from January 1985 to December 1986, 161 cases were confirmed as early gastric cancer by pathologic mapping at Seoul National University Hospital. Among them, the authors reviewed 104 cases of early gastric cancer for the evaluation of diagnostic value of double contrast upper gastrointestinal series. Early gastric cancer was most common in 5th and 6th decade (64%) and male to female ratio was 2:1. Double contrast upper GI series could detect 97 out of 104 cases (93%). Among them, 62 cases were diagnosed as early gastric cancer, 32 as advanced gastric cancer and 3 as benign lesion. Detection rate according to the size was 100% in lesion larger than 2cm and 87% in lesion smaller than 2cm. Predictability of early gastric cancer according to size was 66% in lesion smaller than 3cm and 43% in lesion larger than 3cm. Detection rate according to the location of the tumor was almost similar between gastric body (94%) and antrum (93%), however was very low in anterior wall lesion (70%). Predictability of early gastric cancer was 69% in gastric body lesion, 52% in gastric antral lesion and 44% in greater curvature lesion. Detection rate according to the type of macrospecimen was 100% in type I, III and IIc+III. Type IIb showed the lowest detection rate (75%). Predictability of early gastric cancer was high in type IIc (68%) and low in type I (20%)

    Cancer has been increasingly recognized as a global issue. This is especially true in countries like China, where cancer incidence has increased likely because of changes in environment and lifestyle. However, cancer is not a modern disease; early cases have been recorded in ancient medical books in the West and in China. Here, we provide a brief history of cancer, focusing on cancer of the breast, and review the etymology of ai, the Chinese character for cancer. Notable findings from both Western and Chinese traditional medicine are presented to give an overview of the most important, early contributors to our evolving understanding of human breast cancer. We also discuss the earliest historical documents to record patients with breast cancer.

    Recently, studies have reported that protein glycosylation plays an important role in the occurrence and development of cancer. Gastric cancer is a common cancer with high morbidity and mortality owing to most gastric cancers are discovered only at an advanced stage. Here, we aim to discover novel specific serum glycanbased biomarkers for gastric cancer. A lectin microarray with 50 kinds of tumor-associated lectin was used to detect the glycan profiles of serum samples between early gastric cancer and healthy controls. Then lectin blot was performed to validate the differences. The result of the lectin microarray showed that the signal intensities of 13 lectins showed significant differences between the healthy controls and early gastric cancer. Compared to the healthy, the normalized fluorescent intensities of the lectins PWA, LEL, and STL were significantly increased, and it implied that their specifically recognized GlcNAc showed an especially elevated expression in early gastric cancer. Moreover, the binding affinity of the lectins EEL, RCA-II, RCA-I, VAL, DSA, PHA-L, UEA, and CAL were higher in the early gastric cancer than in healthy controls. These glycan structures containing GalNAc, terminal Galβ 1-4 GlcNAc, Tri/tetraantennary N-glycan, β-1, 6GlcNAc branching structure, α-linked fucose residues, and Tn antigen were elevated in gastric cancer. While the two lectins CFL GNL reduced their binding ability. In addition, their specifically recognized N-acetyl-D-galactosamine structure and (α-1,3) mannose residues were decreased in early gastric cancer. Furthermore, lectin blot results of LEL, STL, PHA-L, RCA-I were consistent with the results of the lectin microarray. The findings of our study clarify the specific alterations for glycosylation during the pathogenesis of gastric cancer. The specific high expression of GlcNAc structure may act as a potential early diagnostic marker for gastric cancer.

    The performance of a room temperature mercuric iodide x-ray detector was investigated as a function of detector bias, amplifier time constant, and detector temperature. A Mn K/sub α/ line of 200 eV FWHM was obtained by using low noise electronics developed for Si(Li) detectors, including a cooled input FET. Measurements of the detector's resolution at various x-ray energies result in a Fano factor of 0.20. Fluorescence bronchoscopy with a violet laser and image intensifier has been developed for imaging the red fluorescence of a tumor-specific agent, hematoporphyrin derivative, that has been injected before the examination. The instrument was developed to localize carcinoma in situ and early, small bronchogenic tumors diagnosed by sputum cytology but invisible on chest x-ray and conventional bronchoscopy, in underground uranium miners and others at risk for lung cancer. In addition to the imaging devices, a video system including a processor and electronics for digital background image subtraction has been developed to enhance contrast. A ratio fluorometer and a rapid-scan spectrum analyzer have been designed for quantitative measurements of fluorescence intensity and dependence on dosage and time after injection of the fluorescent agent. Clinical trials demonstrate detection of carcinoma in situ, and the true positive rate should be improved by the new instrumentation and optimization of time delay and dosage

    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.

    Breast cancer is the most common female cancer and globally remains a major public health concern. The diagnosis and treatment of breast cancer continues to develop. Diagnosis is now more precise, surgery is less mutilating and women now have the option of breast conserving therapy with better cosmesis, and without sacrificing survival. Radiotherapy is more targeted and the selection of patients for adjuvant chemotherapy is based not only on prognostic and predictive factors, but also on newer molecular profiling that will ensure that chemotherapy is given to the patients who need and respond to it. These developments all provide a more tailored approach to the treatment of breast cancer. Management now involves a multidisciplinary team approach in order to provide the highest standard of care for patients throughout their cancer journey from diagnosis through treatment and into follow-up care.

    Different site specificity of second primary cancer following treatment for early stage squamous cell carcinoma of the head and neck was found in the analysis of post-treatment long-term follow up cases. The highest risk of second primary cancer was observed in the oro-hypo-pharynx cancer groups, and the lowest risks were observed in the epi-pharynx cancer and maxillary sinus cancer groups. Squamous cell carcinoma in the irradiated head and neck region with long latency periods could be included in the radiation induced cancer from comparison with post-irradiation cases for malignant lymphoma, benign diseases as well as breast cancers.

    Introduction of prostate cancer screening using PSA leads to a disproportional increase of cancer incidence. Most of those tumors are small and indolent in behavior. When diagnosed, they are usually managed by radical treatment modalities despite the growth of serious adverse events of such therapy. Active surveillance appears to be an alternative treatment approach for the majority of those patients. Author stresses on the particularities of the prostate cancer diagnosed in the PSA era. Show the importance of patient stratification and the utility of the use of nomograms in clinical praxis. The clinical importance of treatment choices based on life expectancy of patient, concomitant diseases on one side and cancer biological behavior in the other side is discussed. Critically discuss the new approach of radiation with proton beams advertising that it remains an experimental therapeutic choice. (author)

    The purpose of this study is to describe the radiologic findings of early colon cancer on double-contrast barium enema. We retrospectively reviewed the double-contrast barium enemas of eight patients (M:F = 6:2; mean age : 67 yrs; range : 48-77 yrs) who were pathologically proven to be early colon cancer. The location, size and gross morphology of lesions was evaluated using double-contrast barium enema, while depth of invasion, degree of differentiation, precancerous lesions and lymph node metastasis were evaluated histopathologically. Early colon cancer was found in the rectum (n=4), sigmoid colon (n=3) and ascending colon (n=1). The size of mass ranged from 2.3 ∼ 8.3 (mean, 4.6) cm. And the polypoid type was most common (n=7); this was subdivided into sessile (Is, n=5), semipedunculated (Isp, n=1) and pedunculated type (Ip, n=1). Another mass was a sessile polypoid combined with a flat depressed lesion. In eight cases, four cancers were confined to the mucosa, while the remaining four had infiltrated the submucosa. Most cancers arose from villous and villotubular adenoma. All cases were well-differentiated adenocarcinoma and no metastasis to lymph nodes had occurred. In early colon cancer, lesions were mainly polypoid and large. Most arose from villous and villotubular adenoma. (author). 19 refs., 1 tab., 3 figs

    It is well documented that cancer is disproportionately distributed in racial/ethnic minority groups and medically underserved communities. In addition, cancer prevention and early detection represent the key defenses to combat cancer. The purpose of this article is to showcase the comprehensive health education and community outreach activities at the H. Lee Moffitt Cancer Center and Research Institute (Moffitt) designed to promote and increase access to and utilization of prevention and early detection services among underserved populations. One of Moffitt's most important conduits for cancer prevention and early detection among underserved populations is through its community education and outreach initiatives, in particular, the Moffitt Program for Outreach Wellness Education and Resources (M-POWER). M-POWER works to empower underserved populations to make positive health choices and increase screening behaviors through strengthening collaboration and partnerships, providing community-based health education/promotion, and increasing access to care. Effective, empowering, and culturally and linguistically competent health education and community outreach, is key to opening the often impenetrable doors of cancer prevention and early detection to this society's most vulnerable populations.

    European experience in endoscopic mucosal resection (EMR) for early gastric cancer is still relatively low, since early stomach cancer is diagnosed at a much lower rate in Europe than in Japan and generally operable patients are referred to surgery for radical resection. Endoscopic mucosal resection or mucosectomy was developed as a promising technology to diagnose and treat mucosal lesions in the esophagus, stomach and colon. In contrast to surgical resection, EMR allows "early cancers" to be removed with a minimal cost, morbidity and mortality. We present the case of a patient with hepatic cirrhosis incidentally diagnosed with an elevated-type IIa early gastric cancer. Echoendoscopy was performed in order to assess the depth of invasion into the gastric wall confirming the only mucosal involvement. We performed an EMR using "cup and suction" method. After the procedure, the patient experienced an acute upper gastrointestinal bleeding from the ulcer bed requiring argon plasma coagulation. The histopathological examination confirmed an early cancer, without involvement of muscularis mucosae. The patient has had an uneventful evolution being well at six months after the procedure

    The aim of this study was to investigate the effectiveness and problems of concurrent radiotherapy with S-1 for T2 glottic carcinoma. The study included 48 patients (22 patients for radiotherapy alone (RT group), 26 patients for radiotherapy concurrent with S-1 (S-1 group) who underwent initial treatment as outpatients for T2 glottic carcinoma at Osaka Medical College. Six of the 26 patients of the S-1 group were suspected to have local recurrence, but 5 of them had necrosis and one had dysplasia. Three patients suffered bilateral vocal cord paralysis and underwent tracheostomy. On the other hand, 4 of the 22 patients of the RT group suffered local recurrence and one patient suffered unilateral vocal cord paralysis. The local control rate of the S-1 group was significantly higher than that of the RT group. In the S-1 group, 5 patients with laryngeal function disorder tended to develop upper and arytenoid cartilage. The local control rate of radiotherapy for T2 glottic carcinoma was improved by concurrent S-1. In the S-1 group, there was no local recurrence, but some cases suffered laryngeal dysfunction, so efforts should be made to preserve laryngeal function. (author)

    We sought to determine the outcomes of office-based autologous fat injection laryngoplasty in the treatment of patients under 50 years old with glottic insufficiency but without neurological problems or acquired organic lesions in the vocal fold. We conducted a retrospective chart review of consecutive patients under 50 years of age who underwent office-based autologous fat injection laryngoplasty for glottic insufficiency. None of the patients presented neurological problems or acquired organic lesions in the vocal fold. Videolaryngostroboscopic data, objective voice assessment, perceptual measurements of vocal quality, and subjective ratings of voice quality were evaluated before and after treatment. The 23 patients (7 men and 16 women) in this study presented significant improvements in phonatory function in terms of maximum phonation time, jitter, grade, asthenia, and Voice Handicap Index-10 (VHI-10) values at 3 months. Significant improvements in terms of jitter, noise-to-harmonic ratio, grade, roughness, breathiness, asthenia, and the VHI-10 values were also observed at 6 months. Glottic insufficiency in younger patients without neurological problems or acquired organic lesions in the vocal fold can be treated effectively using office-based autologous fat injection laryngoplasty. Significant improvements in phonatory function were observed even 6 months after surgery. Copyright © 2018 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

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

    To determine the effect of injection augmentation of the vocal folds on chronic cough symptoms in patients with glottic insufficiency. Medical records from 146 consecutive patients who underwent vocal fold injection augmentation by a fellowship-trained laryngologist between 2013 and 2015 were reviewed. Twenty-three patients (12 male) met inclusion criteria of a vocal fold augmentation injection, cough symptoms lasting more than 8 weeks, and glottic insufficiency as determined by shortened closed phase on stroboscopy. Exclusion criteria included lack of cough complaints, diagnosis of vocal fold immobility, previous history of vocal fold augmentation, and incomplete data sets. Data collected included age, gender, pre- and 1-month postinjection Cough Severity Index (CSI) scores, location of injection (unilateral or bilateral), and patient statement of percent change in symptoms that was recorded at 1-month postinjection visit. Paired t test indicated a significant decrease in CSI scores from pre- (m = 18.5) to 1-month postinjection (m = 12.1) (P = 0.004). Eighteen patients (78.2%) reported a 50% or greater improvement in cough symptoms at the 1-month postinjection visit. Injection augmentation of the vocal folds in the presence of glottic insufficiency appears to improve cough symptoms, as was reported by CSI in patients who are refractory to other medical and behavioral treatments. 4.

    This work is a retrospective analysis to investigate the critical risk factor for the therapeutic effect of endoscopic keel placement on anterior glottic web. Altogether, 36 patients with anterior glottic web undergoing endoscopic lysis and silicone keel placement were enrolled. Their voice qualities were evaluated using the voice handicap index-10 (VHI-10) questionnaire, and improved significantly 3 months after surgery (21.53 ± 3.89 vs 9.81 ± 6.68, P web recurrence during the at least 1-year follow-up. Therefore, patients were classified according to the Cohen classification or web thickness, and the recurrence rates were compared. The distribution of recurrence rates for Cohen type 1 ~ 4 were 28.6, 16.7, 33.3, and 40%, respectively. The difference was not statistically significant (P = 0.461). When classified by web thickness, only 2 of 27 (7.41%) thin type cases relapsed whereas 8 of 9 (88.9%) cases in the thick group reformed webs (P web thickness rather than the Cohen grades. Endoscopic lysis and keel placement is only effective for cases with thin glottic webs. Patients with thick webs should be treated by other means.

    Breast cancer is the most prevalent malignant tumor in women; the etiopathogenesis is unknown and it is associated with high rates of morbidity and mortality. In the fifties, different screening programs were developed for the early detection of breast cancer in the attempt to reduce the mortality attributed to this disease process. Mammography is one of the cornerstones of these programs because of its efficacy in the detection of subclinical tumors. We carried out a retrospective review of nine campaigns for the early detection of breast cancer, studying 11, 328 case reports; among these patients, there were 43 cases of breast cancer. Mammography was positive in 90.6% of these cases. Only in two patients did the image fail to reveal changes indicative of possible neoplasm; in both cases, the breasts involved were very dense.

    Full Text Available Background: Treatment effectiveness and clinical outcome of patients with cervical carcinoma FIGO stage IA1 and IA2 are analyzed in three different time period at the Department of Obstetrics and Gynecology Rijeka, Croatia. Method: Retrospective analysis of the hospital chart of all cervical cancer patients between 1991 and 2005 was conducted with five-year follow up. Results: Data on cervical cancer distribution by stage and five-year survival are presented. Separately analyzed age, histology type and treatment modalities in stage FIGO IA1 and IA2 during three consecutive five-year periods are presented. Conclusions: Conservative surgical approach – conization alone in stage IA1 of the squamous cell car- cinoma is reasonable and safe treatment option for reproductive active women. During observed periods conization became the most used surgical technique applied in almost two third of FIGO IA1 cervical cancer patients. Lymph vascular space invasion in stage IA1 lead to adjunct pelvic lymphadenectomy with unclear clinical benefit. In cervical cancer patients stage IA2 simple hysterectomy and pelvic lymphadenectomy could be accepted as a standard treatment. In these patients further studies are recommended to evaluate other less radical surgical techniques – simple and radical trachelectomy with or without pelvic lymphadenectomy. Radical hysterectomy in both stages IA1 and IA2, based on personal experience and literature data represents a surgical overtreatment and should be abandoned.

    The most significant feature of early carcinoma, be defined as the gastric carcinoma confined in mucosa and submucosal regardless of its size and shape, is its excellent prognosis; 5 year survival rate after operation in early stomach carcinoma amounts to 93 percent in comparison with around 25 percent in advanced carcinoma, and so the detection of this early stomach carcinoma is most important subject to minimize the mortality from stomach carcinoma at the present time. For the diagnosis of the early stomach carcinoma the radiographic study, cytology and gastroscopic examination are practised, and of those the radiographic study has been revealed commonly best results, but by usual method of upper G-I study it is often difficult to diagnose accurately. Therefore, we have been employed the barium and air double contrast method by insertion of the gastric tube. This method is simple and by this method, the adequate amount of air may introduced into the stomach for the best visualization of the mucosal pattern and gastric juice may also aspirated in a case of which the stomach wall could not be coated by barium because of excessive gastric juice. Summary of the results of this studies of early carcinoma detection at the department of radiology, Severance Hospital during 6 months since May 1969 are as followings; of 1407 cases taken upper G-I study with double contrast method, 17 cases were diagnosed as possible early stomach carcinoma radiographically, and then only 6 cases had surgical resection of stomach. Of these 2 cases were confirmed pathologically and one was considered as precancerots lesion

    Almost 100 years have passed since the seminal observations of Schöne showing that vaccination of animals with fetal tissue would prevent the growth of transplantable tumors. Many subsequent reports have affirmed the general idea that immunologic rejection of transplantable tumors, as well as prevention of carcinogenesis, may be affected by vaccination with embryonic/fetal material. Following a decade of intense research on this phenomenon during approximately 1964-1974, interest appears to have waned. This earlier experimental work may be particularly pertinent in view of the rising interest in so-called cancer stem cells. We believe that further work - perhaps involving the use of embryonic stem cells as immunogens - is warranted and that the results reviewed herein support the concept that vaccination against the appearance of cancers of all kinds is a real possibility.

    This study examined whether workplace support, sociodemographic factors and co-morbidity are associated with early retirement or non-employment due to other reasons among breast cancer survivors. We also compared quality of life and chronic symptoms (pain, fatigue, anxiety and depression) among employed, retired and other non-employed breast cancer survivors. We identified breast cancer survivors diagnosed between 1997 and 2002 from either a hospital or a cancer registry in Denmark, Finland, Iceland and Norway (NOCWO study). All patients had been treated with curative intent. Information on employment, co-morbidity and support was collected via a questionnaire. The sample included 1111 working-aged cancer-free survivors who had been employed at the time of diagnosis. We used multinomial logistic regression models to analyse the association of various determinants with early retirement and other non-employment (due to unemployment, subsidized employment or being a homemaker). Low education, low physical quality of life, co-morbidity and pain were associated with both early retirement and other non-employment after cancer. Other non-employed survivors also rated their mental quality of life as lower and experienced anxiety and fatigue more often than all the other survivors. Moreover, they reported a lower level of supervisor support after their diagnosis than the employed survivors. Retired survivors more often reported weak support from colleagues. Differences in ill health and functional status between various groups of non-employed cancer survivors need to be considered when planning policy measures for improving the labour market participation of this population and preventing their early withdrawal from working life.

    Lung cancer is the leading cause of cancer-related deaths among men. In this paper, we propose a pulmonary nodule detection method for early screening of lung cancer based on the improved AlexNet model. In order to maintain the same image quality as the existing B/S architecture PACS system, we convert the original CT image into JPEG format image by analyzing the DICOM file firstly. Secondly, in view of the large size and complex background of CT chest images, we design the convolution neural network on basis of AlexNet model and sparse convolution structure. At last we train our models on the software named DIGITS which is provided by NVIDIA. The main contribution of this paper is to apply the convolutional neural network for the early screening of lung cancer and improve the screening accuracy by combining the AlexNet model with the sparse convolution structure. We make a series of experiments on the chest CT images using the proposed method, of which the sensitivity and specificity indicates that the method presented in this paper can effectively improve the accuracy of early screening of lung cancer and it has certain clinical significance at the same time.

    Nearly one in four breast cancers is diagnosed before the age of 50, and many early-stage premalignant lesions are present but not yet diagnosed. Therefore, we review evidence to support the strategy that breast cancer prevention efforts must begin early in life. This study follows the literature review methods and format. Exposures during childhood and adolescence affect a woman's long-term risk of breast cancer, but have received far less research attention than exposures that occur later in life. Breast tissue undergoes rapid cellular proliferation between menarche and first full-term pregnancy, and risk accumulates rapidly until the terminal differentiation that accompanies first pregnancy. Evidence on childhood diet and growth in height, and adolescent alcohol intake, among other adolescent factors is related to breast cancer risk and risk of premalignant proliferative benign lesions. Breast cancer prevention efforts will have the greatest effect when initiated at an early age and continued over a lifetime. Gaps in knowledge are identified and deserve increase attention to inform prevention.

Conclusion Breast cancer prevention efforts will have the greatest effect when initiated at an early age and continued over a lifetime. Gaps in knowledge are identified and deserve increase attention to inform prevention. PMID:24820413

    In this treatise oral carcinogenesis is briefly discussed, particularly with regard to the number of cell divisions that is required before cancer reaches a measurable size. At that stage, metastatic spread may have already taken place. Therefore, the term "early diagnosis" is somewhat misleading.

    Discovery of disease biomarkers for cancer is a leading focus of early detection. The National Cancer Institute created a network of collaborating institutions focused on the discovery and validation of cancer biomarkers called the Early Detection Research Network (EDRN). Informatics plays a key role in enabling a virtual knowledge environment that provides scientists real time access to distributed data sets located at research institutions across the nation. The distributed and heterogeneous nature of the collaboration makes data sharing across institutions very difficult. EDRN has developed a comprehensive informatics effort focused on developing a national infrastructure enabling seamless access, sharing and discovery of science data resources across all EDRN sites. This paper will discuss the EDRN knowledge system architecture, its objectives and its accomplishments.

    Full Text Available Pancreatic cancer is a common malignant neoplasm of the pancreas with an extremely high mortality. Currently, the early diagnosis of pancreatic cancer is still not ideal. Attention should be paid to some clinical warning symptoms, such as unexplained abdominal and back pain, jaundice, and unexpected diabetes. Additionally, the combined use of CA19-9, CEA, and other tumor markers, the attention to biochemical indicators, the detection of mutation in KAI1 or p53 gene, and the exploration of the value of miRNA in clinical diagnosis are of great significance. On the other hand, ultrasound, CT, MRCP, ERCP, PET-CT, and other imaging methods, as well as effective collection of cytology specimens, should be performed. Thus, there is hope for the early diagnosis of pancreatic cancer.

    Health literacy, the degree to which individuals have the capacity to obtain, process, and understand health information and services needed to make health decisions, is an essential element for early adults (aged 18-44 years) to make informed decisions about cancer. Low health literacy is one of the social determinants of health associated with cancer-related disparities. Over the past several years, a nonprofit organization, a university, and a cancer center in a major urban environment have developed and implemented health literacy programs within healthcare systems and in the community. Health system personnel received extensive health literacy training to reduce medical jargon and improve their patient education using plain language easy-to-understand written materials and teach-back, and also designed plain language written materials including visuals to provide more culturally and linguistically appropriate health education and enhance web-based information. Several sustainable health system policy changes occurred over time. At the community level, organizational assessments and peer leader training on health literacy have occurred to reduce communication barriers between consumers and providers. Some of these programs have been cancer specific, including consumer education in such areas as cervical cancer, skin cancer, and breast cancer that are targeted to early adults across the cancer spectrum from prevention to treatment to survivorship. An example of consumer-driven health education that was tested for health literacy using a comic book-style photonovel on breast cancer with an intergenerational family approach for Chinese Americans is provided. Key lessons learned from the health literacy initiatives and overall conclusions of the health literacy initiatives are also summarized. Copyright © 2017 American Journal of Preventive Medicine.

    Oral cancer is an important health issue. The WHO predicts a continuing worldwide increase in the number of patients with oral cancer, extending this trend well into the next several decades. In the US the projected number of new cases of oral and oropharyngeal cancer will exceed 31,000 per year. Mortality due to cancers in this region exceeds the annual death rate is the US caused by either cutaneous melanoma or cervical cancer. Significant agents involved in the etiology of oral cancer in Western countries include sunlight exposure, smoking and alcohol consumption. Use of the areca or betel nut in many cultures is a major etiological factor outside of the USA. Other etiologic factors associated with oral squamous cell carcinoma, but far less significant statistically, include syphilis and sideropenic dysphagia. Recently, strong evidence for an etiological relationship between human papilloma virus and a subset of head and neck cancers has been noted. It is generally accepted that most sporadic tumors are the result of a multi-step process of accumulated genetic alterations. These alterations affect epithelial cell behavior by way of loss of chromosomal heterozygosity which in turn leads to a series of events progressing to the ultimate stage of invasive squamous cell carcinoma. The corresponding genetic alterations are reflected in clinical and microscopic pathology from hyperplasia through invasiveness. A wide range of mucosal alternations fall within the rubric of leukoplakia. Proliferative verrucous leukoplakia represents a relatively new type of leukoplakia that is separate from the more common or less innocuous form of this condition. Erythroplakia is particularly relevant considering its almost certain relationship with dysplasia or invasive carcinoma. Squamous cell carcinoma will develop from antecedent dysplastic oral mucosal lesions if an early diagnosis has not been made and treatment given. Early diagnosis within stages I and II correspond to a vastly

    Full Text Available Essentially, people’s diet and nutritional status has been changed substantially worldwide and several lines of evidence suggest that these changes are to the detriment of their health. Additionally, it has been well documented that unhealthy diet especially the fast foods, untraditional foods or bad-eating-habits influence the human gut microbiome. The gut microbiota shapes immune responses during human life and affects his/her metabolomic profiles. Furthermore, many studies highlight the molecular pathways that mediate host and symbiont interactions that regulate proper immune function and prevention of cancer in the body. Intriguingly, if cancer forms in a human body due to the weakness of immune system in detriment of microbiome, the removal of cancer stem cells can be carried out through early Calories Restriction with Annual Fasting (AF before tumor development or progress. Besides, fasting can b balance the gut microbiome for enhancement of immune system against cancer formation.

  14. Obesity in Childhood Cancer Survivors: Call for Early Weight Management.

    2015-09-01

    A high prevalence of obesity and cardiometabolic conditions has been increasingly recognized in childhood cancer survivors. In particular, survivors of pediatric acute lymphoblastic leukemia have been found to be at risk of becoming overweight or obese early in treatment, with increases in weight maintained throughout treatment and beyond. Nutrition plays an important role in the etiology of obesity and cardiometabolic conditions and is among the few modifiable factors that can prevent or delay the early onset of these chronic conditions. However, nutritional intake in childhood cancer survivors has not been adequately examined and the evidence is built on data from small cohorts of survivors. In addition, the long-term impact of cancer diagnosis and treatment on survivors' nutritional intake as well as how survivors' nutritional intake is associated with chronic health conditions have not been well quantified in large-scale studies. Promoting family-based healthy lifestyles, preferably at a sensitive window of unhealthy weight gain, is a priority for preventing the early onset of obesity and cardiometabolic conditions in childhood cancer survivors. © 2015 American Society for Nutrition.

    2004-01-01

    Background and purpose: to determine whether the blood hemoglobin concentration correlates with the prognosis of patients with early breast cancer and, if so, whether this is restricted to treatment modality. Patients and methods: data were collected retrospectively from patients with early breast cancer (T1,2 NO-2 MO) who underwent either breast-conserving surgery followed by adjuvant radiotherapy (BCS-RT; n = 96) or a modified radical mastectomy (MRM; n = 194). The effect of preoperative blood hemoglobin level, nodal status, histological grading and hormone receptor status on disease-free survival was determined for both treatment modalities using a cox regression model and visualized by kaplan-meier plots. Results: the blood hemoglobin concentration significantly correlated with disease-free survival of patients receiving BCS-RT (relative risk [RR]: 0.67 per g/dl; p = 0.007). This was independent of other known risk factors for breast cancer patients, as determined by multivariate analysis. By contrast, the blood hemoglobin level had no prognostic significance when patients were treated with MRM. Conclusion: blood hemoglobin concentration seems to affect the prognosis of patients with early breast cancer when a treatment schedule that includes radiotherapy is applied. Reduced radiosensitivity due to diminished tumor oxygenation may be the underlying cause. Confirmative trials and studies intended to elucidate the underlying mechanism are warranted. (orig.)

    Cancer may follow exposure to an environmental agent after many decades. The bacterium Helicobacter pylori, known to be acquired early in life, increases risk for gastric adenocarcinoma, but other factors are also important. In this study, we considered whether early-life family structure affects the risk of later developing gastric cancer among H. pylori+ men. We examined a long-term cohort of Japanese-American men followed for 28 y, and performed a nested case-control study among those carrying H. pylori or the subset carrying the most virulent cagA+ H. pylori strains to address whether family structure predicted cancer development. We found that among the men who were H. pylori+ and/or cagA+ (it is possible to be cagA+ and H. pylori- if the H. pylori test is falsely negative), belonging to a large sibship or higher birth order was associated with a significantly increased risk of developing gastric adenocarcinoma late in life. For those with cagA+ strains, the risk of developing gastric cancer was more than twice as high (odds ratio 2.2; 95% confidence interval 1.2-4.0) among those in a sibship of seven or more individuals than in a sibship of between one and three persons. These results provide evidence that early-life social environment plays a significant role in risk of microbially induced malignancies expressing five to eight decades later, and these findings lead to new models to explain these interactions.

    Full Text Available Background: In order to reduce the probability of later clinical involvement of the axilla and at establishing a sound basis for adjuvant treatment planning axillary dissection is an important operative procedure. So, partial axillary dissection has been applied to decrease the morbidity and postoperative axillary complications.Aim of the work was to study the reliability of partial axillary lymph node dissection in patients with breast carcinoma with clinically negative axilla. Methods: Eighteen patients underwent modified radical mastectomy, while the other two patients who were fulfilling the criteria for conservative breast surgery underwent lumpectomy. All patients did complete axillary lymph nodes dissection. Intraoperative leveling of the axilla was performed and level I axillary lymph nodes were identified according to their relation to pectoralis minor muscle; then they were subjected to intraoperative pathological examination by frozen section examination followed by complete axillary clearance. Then post operative histopathological examination of the tumor and all lymph nodes was done. Results: By intraoperative pathological examination; five patients (25% were found positive for malignant invasion, while 15 patients (75% were pathologically free. While paraffin section showed six patients (30% with malignant invasion, and 14 patients (70% were pathologically free. There was a false negative rate of 5% in level I axillary lymph nodes by intraoperative pathological examination which was positive for metastasis by paraffin section that revealed microinvasion in one lymph node out of 8 in level I. Only two cases out of 20 were found positive for metastasis in level II and III. Conclusion: Partial axillary lymph node dissection is a minimally invasive, feasible and sufficient technique that can predict the axillary lymph node status.

    Objective: To study the frequency of complications, particularly the lymphedema of the arm, after modified radical mastectomy in early breast cancer patients who have not been given post-operative radiotherapy to axilla. Design: Hospital based descriptive study. Results: Median age of these patients was 47 years with a range of 25-58 years. Majority of these patients were stage II (84%) and infiltrating ductal carcinoma was the most frequent type of cancer (88%). Fifty-six percent of these patients had high grade tumors. None of the patients received radiotherapy to axilla after modified radical mastectomy. Early complications documented from history and medical record revealed that seroma formation was the most frequent early complication seen after modified radical mastectomy (20%). Frequent late complications included anterior chest tightness (56%), shoulder dysfunction (36%), lymphedema (26%) and sensory loss (22%). Shoulder dysfunction included limited range of movement in all 18 patients. Gross multiple restrictions were seen in 11 (61.11%) of these patients. Conclusion: It is concluded from this study that lymphedema and shoulder dysfunction are the two major complications in patients of early breast cancer who have undergone modified radical mastectomy without post-operative axillary radiation.

    The incidence of early esophageal adenocarcinoma has been increasing significantly in recent decades. Prognosis depends greatly on the choice of treatment. Early cancers can be treated by endoscopic resection, whereas advanced carcinomas have to be sent for surgery. Esophageal resection is associated with high perioperative mortality (1-5%) even in specialized centers. Early diagnosis enables curative endoscopic treatment option. Patients with gastrointestinal symptoms and a familial risk for esophageal cancer should undergo upper gastrointestinal endoscopy. High-definition endoscopes have been developed with technical add-on that helps endoscopists to find fine irregularities in the esophageal mucosa, but interpreting the findings remains challenging. In this review we discussed novel and old diagnostic procedures and their values, as well as our own recommendations and those of the authors discussed for the diagnosis and treatment of early Barrett's carcinoma. Endoscopic resection is the therapy of choice in early esophageal adenocarcinoma. It is mandatory to perform a subsequent ablation of all residual Barrett's mucosa to avoid metachronous lesions. © 2015 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

    Despite advances in cancer therapy, treating cancer after it has metastasized remains an unmet clinical challenge. In this study we demonstrate that 100 nm liposomes target triple-negative murine breast-cancer metastases post intravenous administration. Metastatic breast cancer was induced in BALB/c mice either experimentally, by a tail vein injection of 4T1 cells, or spontaneously, after implanting a primary tumor xenograft. To track their biodistribution in vivo the liposomes were labeled with multi-modal diagnostic agents, including indocyanine green and rhodamine for whole-animal fluorescent imaging, gadolinium for magnetic resonance imaging (MRI), and europium for a quantitative biodistribution analysis. The accumulation of liposomes in the metastases peaked at 24 h post the intravenous administration, similar to the time they peaked in the primary tumor. The efficiency of liposomal targeting to the metastatic tissue exceeded that of a non-liposomal agent by 4.5-fold. Liposomes were detected at very early stages in the metastatic progression, including metastatic lesions smaller than 2 mm in diameter. Surprisingly, while nanoparticles target breast cancer metastasis, they may also be found in elevated levels in the pre-metastatic niche, several days before metastases are visualized by MRI or histologically in the tissue. This study highlights the promise of diagnostic and therapeutic nanoparticles for treating metastatic cancer, possibly even for preventing the onset of the metastatic dissemination by targeting the pre-metastatic niche.

    Gastric cancer is a frequent malignant tumor worldwide and its early detection is crucial for curing the disease and enhancing patients' survival rate. This study aimed to assess whether the multi-disciplinary team (MDT) can improve the detection rate of early gastric cancer (EGC). The detection rate of EGC at the Digestive Endoscopy Center, Affiliated Hospital, Zunyi Medical College, China between September 2013 and September 2015 was analyzed. MDT for the diagnosis of EGC in the hospital was established in September 2014. The study was divided into 2 time periods: September 1, 2013 to August 31, 2014 (period 1) and September 1, 2014 to September 1, 2015 (period 2). A total of 60,800 patients' gastroscopies were performed during the two years. 61 of these patients (0.1%) were diagnosed as EGC, accounting for 16.44% (61/371) of total patients with gastric cancer. The EGC detection rate before MDT (period 1) was 0.05% (16/29403), accounting for 9.09% (16/176) of total patients with gastric cancer during this period. In comparison, the EGC detection rate during MDT (period 2) was 0.15% (45/31397), accounting for 23% (45/195) of total patients with gastric cancer during this period (P cooperation with Department of Pathology (OR = 10.1, 95% CI 2.39-43.3, P < 0.05). MDT could improve the endoscopic detection rate of EGC.

    The incidence of breast cancer in the Netherlands and the methods of diagnosis and treatment are outlined. A systematic screening of the total female population would result in a number of breast cancers being found at a relatively early stage. The advantages and disadvantages of five methods of screening are discussed: breast self-examination by women, palpation by doctor or para-medical personnel, mammography, ultrasound and thermography. It is concluded that mammography currently appears to be the best method. The risk that the X-rays might cause cancer is negligible. Two large screening projects in the Netherlands are described and the preliminary results discussed. In the appendices, a number of aspects such as the current projects in the Netherlands, the risks of ionizing radiation, and the attitudes and response of women invited for screening, are elaborated upon. A discussion session between an advisory committee and a number of Dutch and foreign experts is also presented (in English). (Auth.)

    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.

    Breast cancer is one of the most common cancers in women, which if detected in early stage can be effectively treated and cured. Early detection is carried out by collecting a sentinel lymph node (SLN) and testing it for cancer. The surgical gamma probe is a hand-held device used in the localization of SLN. It enables the localization of the active node. Isotope Applications Division, BARC has developed indigenously a RIG Surgical Gamma Probe in consultation with the doctors from Rajiv Gandhi Cancer Institute and Research Centre, New Delhi. The system consists of microcomputer-based gamma counting system that displays the number of pulses detected by the probe in counts per second and has an audible signal in direct correlation with the count density. The detector probe is based on the scintillation detector housed in a stainless steel housing with lead collimator. The physical parameters are a high sensitivity of 5000 cps/MBq at probe tip with good spatial resolution. The performance of this probe was clinically evaluated on the basis of spatial resolution and accuracy to detect the active node. (author)

    Full Text Available Lung cancer continues to rank as the leading cause of cancer deaths worldwide. One of the most promising techniques for early detection of cancerous cells relies on sputum cell analysis. This was the motivation behind the design and the development of a new computer aided diagnosis (CAD system for early detection of lung cancer based on the analysis of sputum color images. The proposed CAD system encompasses four main processing steps. First is the preprocessing step which utilizes a Bayesian classification method using histogram analysis. Then, in the second step, mean shift segmentation is applied to segment the nuclei from the cytoplasm. The third step is the feature analysis. In this step, geometric and chromatic features are extracted from the nucleus region. These features are used in the diagnostic process of the sputum images. Finally, the diagnosis is completed using an artificial neural network and support vector machine (SVM for classifying the cells into benign or malignant. The performance of the system was analyzed based on different criteria such as sensitivity, specificity and accuracy. The evaluation was carried out using Receiver Operating Characteristic (ROC curve. The experimental results demonstrate the efficiency of the SVM classifier over other classifiers, with 97% sensitivity and accuracy as well as a significant reduction in the number of false positive and false negative rates.

    Full Text Available H Hameed, J CassidyBeatson West of Scotland Cancer Centre, Glasgow, Scotland, UKAbstract: Capecitabine (Xeloda®, Roche, Basel, Switzerland is a pro-drug of 5-fluorouracil (5-FU, and it is converted to 5-FU in the cancer cell by enzymatic degradation. The role of capecitabine in colorectal cancer has evolved in the last 15 years. In early trials in the metastatic setting, capecitabine has shown superior response rates compared with those achieved with 5-FU (Mayo Clinic regimen (26% vs 17%, with equivalent progression-free survival and overall survival. In the adjuvant setting, the Xeloda in Adjuvant Colon Cancer Therapy (X-ACT trial demonstrated that capecitabine as a single agent led to improvement in relapse-free survival (hazard ratio: 0.86, 95% confidence interval: 0.74–0.99, P = 0.04 and was associated with significantly fewer adverse events than 5-FU plus leucovorin (LV, folinic acid. On the basis of the X-ACT trial, capecitabine was approved by the United States Food and Drug Administration, the National Institute for Clinical Excellence, and the Scottish Medicines Consortium as monotherapy for the adjuvant treatment of stage III colon cancer. The next step was to incorporate capecitabine into combination therapy. The XELOXA trial studied the combination of capecitabine and oxaliplatin (XELOX vs 5-FU/LV and demonstrated 5-year disease-free survival of 66% for XELOX, compared with 60% for 5-FU/LV. The toxicity profile was also quite comparable in the two arms. So both the single agent use of capecitabine as well as in combination with oxaliplatin can be considered as part of the standard of care in management of early colon cancer in appropriately selected patient groups.Keywords: 5-fluorouracil, 5-FU, leucovorin, folinic acid, LV, XELOX, oxaliplatin, FOLFOX

    As the performance of early (H+1 to 4) and late (D1) lympho-scintigraphic images raises organisational problems in outpatient surgery for breast cancer, only early images are generally obtained. The present study evaluated whether two series of images are better than one and defined the advantages of both methodologies On hundred and eighteen patients with infiltrating breast carcinoma (T0, T1 and T2) were included in the study : 87 in group A (early and late images) and 31 in group B (only early images). All patients received two peritumoral injections of 99m Tc-sulphur colloid: 15-18 MBq (group A) and < 15 MBq (group B). During the operation, the patent blue technique was associated with radioactivity detection. The two groups were comparable for histological type and tumour size and localization. Successful localisation of sentinel-nodes on early lympho-scintigraphic images was significantly greater for group B. The sensitivity of early lymphoscintigraphy increased by 10% during the study. Sentinel node detection by the isotopic method alone or the two methods combined was comparable for both groups. In radioactivity detection, the count rate for sentinel nodes versus background (contralateral breast) was superposable for the two groups. During the learning phase, two series of images gave a definite advantage. Subsequently, lymphoscintigraphy performed at + 2 h was sufficient (the results for the two groups became superposable).

    Decision analysis was used to evaluate the results of treatment of T 2 N 0 M 0 glottic carcinoma as presented in the literature. Based on mean values for recurrence, salvage eligibility after recurrence and salvage success, the 5-year survival after radiotherapy and surgery proved to be almost identical, 85 and 86%. If the recurrence rates and the salvage rates were varied, a marginal advantage for surgery in small tumours and a major advantage in more extended tumours was seen if only survival is considered. To take the quality of speech into account, a utility analysis was performed. A utility scale was defined ranging from 0.0 as the value for death, to 1.0 for a successfully irradiated patient with preservation of normal speech. A utility of 0.99 or less for the laryngectomized patient would favour radiotherapy over surgery for all T 2 tumours. In patients with T 2b tumours and in extreme circumstances, e.g. if failure rates of radiotherapy are extremely low, an exact assessment of patient utilities may be pivotal. Under normal circumstances radiotherapy is preferred for T 2 N 0 M 0 glottic carcinoma if both survival and the quality of speech are taken into account. (author). 39 refs.; 5 figs.; 1 tab

    It is still undecided if endoscopic laser surgery or radiotherapy is the preferable treatment in extended T1 and limited T2 glottic tumors. Health utilities assessed from patients can aid in decision-making. Patients treated for extended T1 or limited T2 glottic carcinoma by laser surgery (n = 12) or radiotherapy (n = 14) assigned health utilities using a visual analog scale (VAS), time tradeoff (TTO) technique and scored their voice handicap using the Voice Handicap Index (VHI). VAS and TTO scores were slightly lower for the laser group compared to the radiotherapy group, however, not significantly so. The VHI showed a correlation with the VAS score, which was very low in both groups and can be considered (near) normal. Patients show no clear preference for the outcomes of laser surgery or radiotherapy from a quality of life (QOL) or voice handicap point of view. These data can now be incorporated into decision-making models. © 2017 Wiley Periodicals, Inc. Head Neck, 2017 © 2016 Wiley Periodicals, Inc.

    Full Text Available Cancer may follow exposure to an environmental agent after many decades. The bacterium Helicobacter pylori, known to be acquired early in life, increases risk for gastric adenocarcinoma, but other factors are also important. In this study, we considered whether early-life family structure affects the risk of later developing gastric cancer among H. pylori+ men.We examined a long-term cohort of Japanese-American men followed for 28 y, and performed a nested case-control study among those carrying H. pylori or the subset carrying the most virulent cagA+ H. pylori strains to address whether family structure predicted cancer development. We found that among the men who were H. pylori+ and/or cagA+ (it is possible to be cagA+ and H. pylori- if the H. pylori test is falsely negative, belonging to a large sibship or higher birth order was associated with a significantly increased risk of developing gastric adenocarcinoma late in life. For those with cagA+ strains, the risk of developing gastric cancer was more than twice as high (odds ratio 2.2; 95% confidence interval 1.2-4.0 among those in a sibship of seven or more individuals than in a sibship of between one and three persons.These results provide evidence that early-life social environment plays a significant role in risk of microbially induced malignancies expressing five to eight decades later, and these findings lead to new models to explain these interactions.

    Full Text Available Gastric carcinoma is one of the major causes of cancer-related mortality worldwide. Early detection and treatment leads to an excellent prognosis in patients with early gastric cancer (EGC, whereas the prognosis of patients with advanced gastric cancer (AGC remains poor. It is unclear whether EGCs and AGCs are distinct entities or whether EGCs are the beginning stages of AGCs. We performed whole exome sequencing of four samples from patients with EGC and compared the results with those from AGCs. In both EGCs and AGCs, a total of 268 genes were commonly mutated and independent mutations were additionally found in EGCs (516 genes and AGCs (3104 genes. A higher frequency of C>G transitions was observed in intestinal-type compared to diffuse-type carcinomas (P = 0.010. The DYRK3, GPR116, MCM10, PCDH17, PCDHB1, RDH5 and UNC5C genes are recurrently mutated in EGCs and may be involved in early carcinogenesis.

    Summary Exosomes are lipid bilayer-enclosed extracellular vesicles (EVs) that contain proteins and nucleic acids. They are secreted by all cells and circulate in the blood. Specific detection and isolation of cancer cell-derived exosomes in circulation is currently lacking. Using mass spectrometry analyses, we identified a cell surface proteoglycan, glypican-1 (GPC1), specifically enriched on cancer cell-derived exosomes. GPC1+ circulating exosomes (crExos) were monitored and isolated using flow cytometry from the serum of cancer patients and mice with cancer. GPC1+ crExos were detected in the serum of patients with pancreas cancer with absolute specificity and sensitivity, distinguishing healthy subjects and patients with a benign pancreas disease from patients with early and late stage pancreas cancer. Levels of GPC1+ crExos correlate with tumor burden and survival in patients pre- and post-surgical tumor resection. GPC1+ crExos from patients and from mice with spontaneous pancreas tumors driven by oncogenic KRAS contained RNA with specific KRAS mutation, and it emerges as a reliable biomarker for the detection of PanIN lesions despite negative signal by MRI in mice. GPC1+ crExos may serve as a potential non-invasive diagnostic and screening tool to detect early stages of pancreas cancer to facilitate possible curative surgical therapy. PMID:26106858

    Nipple discharge (ND) can be the earliest presenting symptom of breast cancer. We hereby present two cases of breast cancer with no palpable mass manifesting as isolated ND, which was whitish in color. In both cases, cytology of the discharge revealed highly pleomorphic cells indicating a high grade malignancy. Mammography showed diffuse, extensive microcalcifications. Simple mastectomy with axillary clearance was done. Histology in both cases revealed diffusely spreading intraductal carcinoma, with focus of microinvasion in one case. ND if scanty or not blood stained is often ignored by the patients and at times, the clinicians. This article highlights that ND can be an early warning sign of intraductal carcinomas that are non-invasive in early stage. Irrespective of the color or nature of the discharge, unilateral ND needs to be evaluated. Proper clinical assessment, cytological evaluation of the ND, and mammography ought to be performed in all such cases. Considering the low level of awareness in women regarding the warning signs of breast cancer, the current focus is to create “breast awareness.” Women should be sensitized to recognize any unusual changes in their breasts and report to their health care providers at the earliest.

    Full Text Available This review examines studies of radiofrequency ablation (RFA of nonsmall cell lung cancer (NSCLC and discusses the role of RFA in treatment of early-stage NSCLC. RFA is usually performed under local anesthesia with computed tomography guidance. RFA-associated mortality, while being rare, can result from pulmonary events. RFA causes pneumothorax in up to 63% of cases, although pneumothorax requiring chest drainage occurs in less than 15% of procedures. Other severe complications are rare. After RFA of stage I NSCLC, 31–42% of patients show local progression. The 1-, 2-, 3-, and 5-year overall survival rates after RFA of stage I NSCLC were 78% to 100%, 53% to 86%, 36% to 88%, and 25% to 61%, respectively. The median survival time ranged from 29 to 67 months. The 1-, 2-, and 3-year cancer-specific survival rates after RFA of stage I NSCLC were 89% to 100%, 92% to 93%, and 59% to 88%, respectively. RFA has a higher local failure rate than sublobar resection and stereotactic body radiation therapy (SBRT. Therefore, RFA may currently be reserved for early-stage NSCLC patients who are unfit for sublobar resection or SBRT. Various technologies are being developed to improve clinical outcomes of RFA for early-stage NSCLC.

    Mutations in the mitochondrial genome (mtgenome) have been associated with cancer and many other disorders. These mutations can be point mutations or deletions, or admixtures (heteroplasmy). The detection of mtDNA mutations in body fluids using resequencing microarrays, which are more sensitive than other sequencing methods, could provide a strategy to measure mutation loads in remote anatomical sites. We determined the mtDNA mutation load in the entire mitochondrial genome of 26 individuals with different early stage cancers (lung, bladder, kidney) and 12 heavy smokers without cancer. MtDNA was sequenced from three matched specimens (blood, tumor and body fluid) from each cancer patient and two matched specimens (blood and sputum) from smokers without cancer. The inherited wildtype sequence in the blood was compared to the sequences present in the tumor and body fluid, detected using the Affymetrix Genechip ® Human Mitochondrial Resequencing Array 1.0 and supplemented by capillary sequencing for noncoding region. Using this high-throughput method, 75% of the tumors were found to contain mtDNA mutations, higher than in our previous studies, and 36% of the body fluids from these cancer patients contained mtDNA mutations. Most of the mutations detected were heteroplasmic. A statistically significantly higher heteroplasmy rate occurred in tumor specimens when compared to both body fluid of cancer patients and sputum of controls, and in patient blood compared to blood of controls. Only 2 of the 12 sputum specimens from heavy smokers without cancer (17%) contained mtDNA mutations. Although patient mutations were spread throughout the mtDNA genome in the lung, bladder and kidney series, a statistically significant elevation of tRNA and ND complex mutations was detected in tumors. Our findings indicate comprehensive mtDNA resequencing can be a high-throughput tool for detecting mutations in clinical samples with potential applications for cancer detection, but it is

    Trastuzumab therapy given in combination with one of several chemotherapy regimens is currently considered the standard of care for the treatment of early-stage, human epidermal growth factor receptor-2 (HER2) -positive breast cancer. The treatment with trastuzumab is due to a significant impact on the survival part of the standard adjuvant treatment of patients with HER2-positive breast cancer. Patients treated with postoperative breast or chest wall irradiation receive trastuzumab concomitant with radiotherapy. In a small proportion of patients trastuzumab causes cardiotoxicity. Preclinical findings indicate a radiosensibilizing effect of trastuzumab in breast cancer cells, but it is not yet clear whether it radiosensibilizes cells of healthy tissues too. Special attention is required when left breast or left thoracic wall is irradiated in patient receiving trastuzumab, because long-term effects of the concurrent treatment with trastuzumab and radiotherapy are not yet known. In an era where more patients are surviving a diagnosis of breast cancer, better understanding and earlier detection of therapy-induced cardiac toxicity will be of paramount importance

    To evaluate changes in the serum levels of prostate specific antigen (PSA), %free PSA and -2proPSA biomarkers, and prostate health index (PHI) in the diagnostic algorithm of early prostate cancer. The Immunoanalytical Laboratory of the University Hospital in Pilsen examined sera from 263 patients being treated at the Hospital's Urology Department with suspected prostate cancer who had undergone biopsies and were divided into a benign and malignant group. The monitored biomarkers were measured using chemiluminescence. All statistical analyses were calculated using the SAS software. We found statistically significantly increased levels of -2proPSA, PHI and PSA and decreased levels of %freePSA in patients diagnosed with prostate cancer by prostate biopsy vs. patients with benign prostatic hypertrophy (median values: -2proPSA: 16 vs. 21 ng/l, PHI: 35 vs. 62, total PSA: 7.2 vs. 7.7 μg/l and %free PSA: 16.7 vs. 11.7%). Receiver operating characteristic curves showed the best performance for PHI compared to other markers. The assessment of -2proPSA and the calculation of PHI appear to be of great benefit for a more accurate differential diagnosis of benign hyperplasia and prostate cancer.

    We are developing micropreconcentrators based on micro/nanotechnology to detect trace levels of volatile organic compound (VOC) gases contained in human and canine exhaled breath. The possibility of using exhaled VOC gases as biomarkers for various cancer diagnoses has been previously discussed. For early cancer diagnosis, detection of trace levels of VOC gas is indispensable. Using micropreconcentrators based on MEMS technology or nanotechnology is very promising for detection of VOC gas. A micropreconcentrator based breath analysis technique also has advantages from the viewpoints of cost performance and availability for various cancers diagnosis. In this paper, we introduce design, fabrication and evaluation results of our MEMS and nanotechnology based micropreconcentrators. In the MEMS based device, we propose a flower leaf type Si microstructure, and its shape and configuration are optimized quantitatively by finite element method simulation. The nanotechnology based micropreconcentrator consists of carbon nanotube (CNT) structures. As a result, we achieve ppb level VOC gas detection with our micropreconcentrators and usual gas chromatography system that can detect on the order of ppm VOC in gas samples. In performance evaluation, we also confirm that the CNT based micropreconcentrator shows 115 times better concentration ratio than that of the Si based micropreconcentrator. Moreover, we discuss a commercialization idea for new cancer diagnosis using breath analysis. Future work and preliminary clinical testing in dogs is also discussed.

    Roentgenological findings of the fine reliefs in the non-cancerous portion were studied in 61 patients with early gastric cancer by double contrast examination. Incidence of the various types of the fine reliefs in the non-cancerous portion were as follows;verrucae 4 %, granularity 34 %, fine granularity 58 %, islet 24 %, network 17 % and irregular network 16 %, respectively. Fine granularity and network were observed in 61 % and 46 % of the cases with poorly differentiated adenocarcinoma, respectively. Granularity, fine granularity and irregular network were observed in 30 %, 55 % and 40 % of the cases with signet-ring cell carcinoma, respectively. Granularity, fine granularity and islet were observed in 41 %, 59 % and 30 % of the cases with tubular adenocarcinoma, respectively. These results suggest that fine reliefs in the non-cancerous portion of the stomach with early gastric cancer showed both findings those found in atrophic gastritis (verrucae, granularity, fine granularity and network) and those in gastric cancer (granularity, fine granularity, islet and irregular network).

    Although self-efficacy is considered a key psychological resource in adapting to chronic physical illness, this construct has received less attention among individuals coping with cancer. To examine changes in cancer self-efficacy over time among women with early stage breast cancer and associations between task-specific domains of self-efficacy and specific psychological, relationship, and functional outcomes. Ninety-five women diagnosed with early stage breast cancer completed surveys postsurgery and 1 year later. Cancer-related self-efficacy was relatively stable over 1 year, with only 2 domains of efficacy-(a) Activity Management and (b) Self-Satisfaction-evidencing significant increases over the 1-year time period. Cross-sectional findings were relatively consistent with predictions and suggested that specific domains of self-efficacy were more strongly related to relevant domains of adaptation. Longitudinal findings were not as consistent with the domain-specificity hypothesis but did suggest several predictive associations between self-efficacy and outcomes. Personal Management self-efficacy was associated with higher relationship satisfaction, higher Communication Self-Efficacy was associated with less functional impairment, and higher Affective Management self-efficacy was associated with higher self-esteem 1 year later. Specific domains of cancer-related self-efficacy are most closely related to relevant areas of adaptation when considered cross-sectionally, but further study is needed to clarify the nature of these relationships over time.

    The ends of eukaryotic linear chromosomes are protected from undesired enzymatic activities by a nucleoprotein complex called the telomere. Expanding evidence indicates that telomeres have central functions in human aging and tumorigenesis. While it is undoubtedly important to follow current advances in telomere biology, it is also fruitful to be well informed in seminal historical studies for a comprehensive understanding of telomere biology, and for the anticipation of future directions. With this in mind, I here summarize the early history of telomere biology and current advances in the field, mostly focusing on mammalian studies relevant to aging and cancer.

    B-cell leukemia 3 (Bcl-3) is a member of the inhibitor of κB family, which regulates a wide range of biological processes by functioning as a transcriptional activator or as a repressor of target genes. Elevated expression, sustained nuclear accumulation, and uncontrolled activation of Bcl-3 causes increased cellular proliferation or survival, dependent on the tissue and type of stimuli. We retrospectively reviewed patients who were diagnosed with colorectal cancer at Skåne University Hospital in Malmö between 1st of January 1990 and 31st of December 1991. Bcl-3 localization in colorectal cancer was assessed by immunohistochemistry on tissue microarray and freshly isolated colon from patients. Correlation between Bcl-3 localization and clinicopathological parameters of the cohort were evaluated using the Spearman rank-order correlation coefficient. In addition, Bcl-3 expression and localization in colon adenocarcinoma cells were analysed by western blot, immunohistochemistry and subcellular fractionation separately. We found that Bcl-3 was mainly localized in the cytoplasm in the tumour tissue isolated from colon cancer patients. Normal colon samples from the same patients showed Bcl-3 localization in the nucleus. In three out of six colon cancer cell lines, we detected elevated levels of Bcl-3. In these cell lines Bcl-3 was accumulated in the cytosol. We confirmed these findings by analysing Bcl-3 localization in a colon tissue micro array consisting of 270 cases. In these samples Bcl-3 localization correlated with the proliferation marker Ki-67, but not with the apoptotic marker Caspase 3. These findings indicate that analysis of the subcellular localization of Bcl-3 could be a potential-early diagnostic marker in colon cancer

    Full Text Available The results of photodynamic therapy (PDT for early central lung cancer are represented in the article. The study included 37 patients (52 tumor lesions. For 52 lesions pre-invasive cancer (carcinoma in situ was determined in 6 cases, squamous cell cancer with invasion within mucosal and submucosal layers of bronchial wall – in 46 cases. 51 tumors were primary lesion, 1 – residual after radiotherapy. 17 of 37 patients underwent previous surgical or combined modality treatment for cancer in other anatomical sites. For PDT we used photosensitizers photogem, photosens and radachlorine. The treatment response was assessed 1 months later by data of endoscopy and morphological study, CT, US and endosonography. Complete regression was achieved in 86,5% of cases, partial regression – in 13,5%. The efficacy of PDT was depended on tumor size. For lesion up to 1 cm in size complete regression was in 100% of cases, from 1.5 cm to 2.0 cm – in 28.6%, for tumors more than 2 cm the complete regression was not achieved. The recurrence of tumor was diagnosed in 2 patients in the period from 1 to 5 years with following successful repeated courses of PDT. Adverse effects included inflammation changes in mucosa at the PDT region with transient (up to 6-7 days local fibrinous endobronchitis with obturation of segmental bronchial lumen by fibrin membranes (7 patients, scar stenosis of segmental bronchus (2 patients. All patients had increased sensitivity to sun exposure, mild skin burns at exposed areas of body were in 2 patients. The results showed that method was highly efficient and applicable for pre-invasive central lung cancer and in patients with multiple primary bronchial lesions and high risk of surgical complications.

    Full Text Available The experience of photodynamic therapy for early gastric cancer is described in the article. The treatment results in 68 patients who were excluded for convenient surgical treatment because of advanced age or severe co-morbidity are represented. 63 patients had single tumor, 5 patients – 2 tumors. Four Russian agents: photogem, photosens, radaсhlorin and alasens, were used for photodynamic therapy. The treatment session was performed under local anesthesia during routine endoscopy with diode laser with wavelength consistent with photosensitizer (photogem – 630 nm, photosens – 670 nm, alasens-induced protoporphyrin IX – 635 nm, radaсhlorin – 662 nm. The short-term results were analyzed 1 month after treatment according to endoscopy, morphological study, CT, ultrasound or endosonography. For 73 lesions complete regression was observed in 53 (72.6% and partial regression in 20 tumors (27.4%. The efficacy of photodynamic therapy was shown to be directly associated with tumor size. Thus, for tumors up to 1 cm regression occurred in 100% of cases, up to 1.5 cm – in 70.8%, up to 3 cm – in 65.2%, up to 5 cm – in 58.3%. The median survival rates accounted for 7.31 years, 3-year survival – 83±5%, 5-year - 69±8%. The experience showed that the developed method of photodynamic therapy was promising in treatment for early gastric cancer as an alternative to surgery.

    Mortality rates for cervical cancer (CC) in Chile are higher than those of developed countries and it has an unequal socioeconomic distribution. The recognition of human papilloma virus (HPV) as the causal agent of cervical cancer in the early 80's changed the prevention paradigms. Current goals are to prevent HPV infection by vaccination before the onset of sexual activity and to detect HPV infection in women older than 30 years. This article reviews CC prevention and early detection methods, discusses relevant evidence to support a change in Chile and presents an innovation proposal. A strategy of primary screening based on HPV detection followed by triage of HPV-positive women by colposcopy in primary care or by cytological or molecular reflex testing is proposed. Due to the existence in Chile of a well-organized nationwide CC prevention program, the replacement of a low-sensitivity screening test such as the Papanicolau test with a highly sensitive one such as HPV detection, could quickly improve the effectiveness of the program. The program also has a network of personnel qualified to conduct naked-eye inspections of the cervix, who could easily be trained to perform triage colposcopy. The incorporation of new prevention strategies could reduce the deaths of Chilean women and correct inequities.

    Full Text Available Objective: to evaluate the effect of the metabolic antihypoxant cytoflavin on the course of early postanesthetic recovery in patients operated on for various cancers. Subjects and methods: Fifty-seven patients aged 30 to 65 years, operated on for gynecological cancer, were examined. The patients were divided into 2 groups: 1 28 patients who took cytoflavin and 2 29 who did not. At the end of an operation, the agent was intravenously injected in a dose of 10 ml in a mixture with an equal volume of 0.9% sodium chloride solution. Thiopental sodium was used for initial anesthesia; arduan was employed to maintain muscle relaxation. Neuroleptic analgesia with fentanyl and droperidol or ataralgesia (fentanyl + relanium was applied in both groups. The levels of hemoglobin, glucose, sodium, potassium, calcium, malonic dialdehyde (MDA (Andreyev’s test, antioxidative activity (AOA (Semenov’s test were measured to evaluate the functional state of patients. The rating system for determining the recovery of consciousness, respiration, and motor activity, proposed by Aldret and Kroulik [8], and Bidway’s psychological testing, blood oxygen saturation and cardiac performance monitoring (TRITON, Russia and some others were used to evaluate the efficacy of the drug in the early postanesthetic period. The results were statistically processed using Microsoft Excel and a package of Biostatistics 6.0. Results. The use of cytoflavin at the end of surgery has been established to have a beneficial effect on the early recovery period. This is manifested as shorter recovery of consciousness and respiration mainly in the ataralgesia group; fair oxygen saturation, lower MDA concentrations and higher AOA are revealed. Conclusion. Cytoflavin significantly reduces the recovery of consciousness and adequate respiration and the incidence of the fever, muscle tremor syndrome and fails to favor the occurrence of hypoglycemia.

    This paper describes the strategy for improving the poor prognosis of the pancreatic (P) cancer by its early imaging diagnosis followed by resection, based on recent findings on its high risk group. Epidemiological studies have revealed that patients with diabetes, chronic pancreatitis, intraductal papillary-mucious tumor, P cyst, familial history of P cancer, and hereditary P cancer syndrome are involved in the high risk group of P cancer. Imaging diagnosis with CT and/or endoscopic ultrasonography (EUS) followed by histological confirmation for resection can be a useful approach to improve the prognosis in those high risk, asymptomatic individuals with abnormal levels of P enzyme and tumor marker, and with US findings of P ductal dilation and cyst. The guideline 2006 for P cancer by Japan Pancreas Society shows the algorithm leading to the final diagnosis for the positive high risk group: firstly, CT and/or MRCP (MR cholangiopancreatography (CP)); or, in case of uncertainty, EUS and/or ERCP (E retrograde CP) and/or PET; and finally, cytological, histological diagnosis. The newer approach proposed recently for the group is: multi detector row (MD)-CT and EUS; then cytodiagnosis guided by ERCP and/or with fine needle aspiration by EUS, also a promising early diagnosis. As well, molecular biological approaches are supposedly useful for the future diagnosis. (R.T.)

    Full Text Available Ultrasonography (US is currently considered the first-line examination in the detection and characterization of breast lesions including the evaluation of breast cancer. Yet only few single-center cohort studies analyzing breast US in the framework of screening could be identified. In spite of mammography consider as the primary method for screening especially the noteworthy ability of microcalcifications detection. US is good in mass or mass- like lesion detection, especially in the dense breast population that proved by the study of ACRIN 6666. A lobular hypoechoic area; lesion with ductal extension and dilatation; and a hypoechoic nodular lesion with a dilated lactiferous duct leading to the retroareolar region, that were the common ultrasound findings in Ductal carcinoma in situ (DCIS and probably related to nuclear grade of cancer. Computer programs have been developed and approved for use in clinical practice, the application including CAD (computer aided/assisted detection/diagnosis, ABUS (automated breast US, elastography and microbubbles in contrast-enhanced ultrasound. Furthermore the standardized scanning; improving with computer technology implementation and familiar to the picture of DCIS is necessary for progress the competence of early breast cancer detection.

    This perspective on Boyd et al. (beginning on page 1398 in this issue of the journal) discusses recent published research examining the interplay between social stress and breast cancer. Cross-disciplinary studies using genetically defined mouse models and established neonatal and peripubertal paradigms of social stress are illuminating biological programming by diverse early-life experiences for the risk of breast cancer. Understanding the mechanisms underlying this programming can lead to the identification of risk factors and sensitive developmental windows, enabling improved prevention and treatment strategies for this devastating disease. ©2010 AACR.

    The purpose of this study is to evaluate the benefits of mammography in general and particularly as a screening method in the early detection of breast cancer in our hospital. All the cases of breast carcinoma registered in our section between 1989 and 1995 were reviewed retrospectively. The total number of carcinomas was 775, 168 (22%) of which were diagnosed solely on the basis of mammography. The percentage of carcinomas detected on the basis of mammography alone increased progressively (from 13% in 1989-1990 to 28% in 1994-1995), coinciding with a progressive rise in the volume of screening mammography. Early carcinomas, referring to those in stages O or I, represented 67% of those detected by mammography in general and 17% of those detected by palpation (p<0.001). The proportion was even greater among cases of carcinoma detected exclusively by screening mammography (78 versus 17%; p<0.001). Although mammography has been instrumental in increasing the rate of early detection of breast carcinoma in our center, a large number of patients still present with palpable lesions. Thus, a greater effort should be made to increase the practice of mammography in asymptomatic women. (Author) 13 refs

    In this paper, we describe the comparative study as to the immobilization of the portal skin with or without shell. From May 1982 through December 1982, patients with carcinoma of the pharynx or larynx were selected to investigate the immobilization during the treatment. They were treated with parallel opposing portals of 4MV X-ray (NELAC-1004) in supine position. In the group of patients without shell, 4 early glottic cancer patients were selected for the pilot study and 30 treatment data were available for comparison with the movement during the treatment. In the group of patients with shell, 4 patients with early glottic cancer were consecutively selected for this study and 44 data of the intratreatment movement were obtained. As to the pharyngeal cancer patients, 61 controlled data were obtained from 9 patients and 177 data from 21 patients treated with the use of shell. This work clearly indicates that better immobilization is obtained in the patients treated with the employment of shell (p<<0.001). To investigate the reproducibility of the treatment portals, the data were obtained from 240 sheets of verification film taken for the 28 patients with head and neck cancer throughout the course of radiotherapy. All of these patients were treated with above described shell and fixing device. Mean values of the error of reproducibility are from 1.87mm to 2.81mm with the range of 95% confidence limits from 1.49mm to 2.25mm and from 1.86. to 3.75mm, respectively. (J.P.N.)

    The Aim of this level 3 good clinical practice guideline is to help physicians, women and patients in decision making about the appropriate health care for early detection of breast cancer. The principle of early detection of breast cancer comprise the detection and diagnosis of premalignant breast tumors (stage 0, Carcinoma in situ), risk reduction of cancer development as well as the detection and diagnosis of breast cancer at an early stage (stage I), with a 90% chance of cure as shown by a large number of clinical trials. To establish a nation wide, comprehensive quality assuring program for the early detection of breast cancer the guideline summarized in the following paper offers the basis for a timely mortality reduction of breast cancer. The cure of early stage disease will be additionally possible by less invasive treatment allowing patients to maintain quality of life. The guideline leads to a major improvement of women's health care. (orig.) [de

    Early prostate cancer antigen is a nuclear matrix protein that was recently shown to be expressed in prostate adenocarcinoma and adjacent benign tissue. Previous studies have demonstrated early prostate cancer antigen expression in benign prostate tissue up to 5 years before a diagnosis of prostate carcinoma, suggesting that early prostate cancer antigen could be used as a potential predictive marker. We evaluated early prostate cancer antigen expression by immunohistochemistry using a polyclonal antibody (Onconome Inc., Seattle, Washington) on benign biopsies from 98 patients. Biopsies were obtained from 4 groups that included 39 patients with first time negative biopsy (group 1), 24 patients with persistently negative biopsies (group 2), 8 patients with initially negative biopsies who were subsequently diagnosed with prostate carcinoma (group 3) and negative biopsies obtained from 27 cases where other concurrent biopsies contained prostate carcinoma (group 4). Early prostate cancer antigen staining was assessed by 2 of the authors who were blind to the group of the examined sections. Staining intensity (range 0 to 3) and extent (range 1 to 3) scores were assigned. The presence of intensity 3 staining in any of the blocks of a biopsy specimen was considered as positive for early prostate cancer antigen for the primary outcome in the statistical analysis. In addition, as secondary outcomes we evaluated the data using the proportion of blocks with intensity 3 early prostate cancer antigen staining, the mean of the product of staining intensity and staining extent of all blocks within a biopsy, and the mean of the product of intensity 3 staining and extent. Primary outcome analysis revealed the proportion of early prostate cancer antigen positivity to be highest in group 3 (6 of 8, 75%) and lowest in group 2 (7 of 24, 29%, p=0.04 for differences among groups). A relatively higher than expected proportion of early prostate cancer antigen positivity was present in

    Results of large prospective trials, often based on selected series and optimal treatment techniques, indicate that breast conserving therapy is appropriate for most patients with early breast cancer. Questions remain regarding the therapeutic outcome in common practice. We report on a series of 206 consecutive, unselected patients treated with current radiotherapy procedures. The Kaplan-Meier evaluation showed 5- and 8-year survival rates (93%, 91%), distant disease-free survival rates (87%, 85%) and local relapse-free survival rates (90%, 88%) that were comparable to those of the conservative arms in reported randomised trials and to the data from retrospective studies reported by authoritative institutions. However, subanalysis according to prognostic factors such as menopausal status, age and axillary nodal status was of limited value, due to the small number of cases. (orig.)

    This study was performed to evaluate the cosmetic outcome of conservative treatment for early breast cancer and to analyze the factors influencing cosmetic outcome. From February 1992 through January 1997, 120 patients with early breast cancer were treated with conservative surgery and postoperative radiotherapy. The types of conservative surgery were quadrantectomy and axillary node dissection for 108 patients (90%) and lumpectomy or excisional biopsy for 10 patients (8.3%). Forty six patients (38%) received adjuvant chemotherapy (CMF or CAF). Cosmetic result evaluation was carried out between 16 and 74 months (median, 33 months) after surgery. The cosmetic results were classified into four categories, i.e., excellent, good, fair, and poor. The appearances of the patients' breasts were also analyzed for symmetry using the differences in distances from the stemal notch to right and left nipples. A logistic regression analysis was performed to identify independent variables influencing the cosmetic outcome. Cosmetic score was excellent or good in 76% (91/120), fair in 19% (23/120) and poor in 5% (6/ 120) of the patients. Univariate analysis showed that tumor size (T1 versus T2) (p=0.04), axillary node status (NO versus N1) (p=0.0002), extent of surgery (quadrantectomy versus lumpectomy or excisional biopsy) (p=0.02), axillary node irradiation (p=0.0005) and chemotherapy (p=0,0001) affected cosmetic score. Multivariate analysis revealed that extent of surgery (p=0.04) and chemotherapy (p=0.0002) were significant factors. For breast symmetry, univariate analysis confirmed exactly the same factors as above. Multivariate analysis revealed that tumor size (p=0.003) and lymph node status (p=0.007) affected breast symmetry. Conservative surgery and postoperative radiotherapy resulted in excellent or good cosmetic outcome in a large portion of the patients. Better cosmetic results were achieved generally in the group of patients with smaller tumor size, without axillary

The nutrition index, liver function, patient generated subjective global assessment (PG-SGA) score, the post-operation complications, the hospital stay and hospitalization expense of the postoperative patient after total gastrectomy, admitted to our Department of Surgery from May 2011 to May 2013 were analyzed retrospectively. A total of 72 patients including 37 cases in the EEN group and 35 cases in the TPN group were recruited. Hypoalbuminemia gradually improved in the EEN group about 3-5 days, but it did not increase until average 21 days in the TPN group. The body weight decreased in the EEN group during the first 2 weeks and recovered gradually in 21 days; body weight in the TPN group was significantly lower than the EEN group at 21 days (pnutrition indicators. The incidence of complications in the EEN group and TPN group were 8.1% and 25.7% respectively, with no significant differences (p>0.05).

    In the present study, we evaluated the relationship between nutritional status, disease stage and quality of life (QoL) in 100 patients recently diagnosed with gastric carcinoma. The patients' nutritional status was investigated with anthropometric, biochemical, inflammatory and functional variables; and we also evaluated the nutritional risk with the Nutritional Risk Screening 2002. Oncological staging was standard. QoL was evaluated using the Functional Assessment of Anorexia/Cachexia Therapy questionnaire. The statistical correlation between nutritional risk score (NRS) and oncological characteristics or QoL was evaluated using both univariable and multivariable analyses. Weight loss and reduction of food intake were the most frequent pathological nutritional indicators, while biochemical, inflammatory and functional variables were in the normal range. According to NRS, thirty-six patients were malnourished or at risk for malnutrition. Patients with NRS ≥ 3 presented a significantly greater percentage of stage IV gastric cancer and pathological values of C-reactive protein, while no correlation was found with the site of tumour. NRS was negatively associated with QoL (P gastric cancer malnutrition is frequent at diagnosis and this is likely due to reduction in food intake. Moreover, NRS is directly correlated with tumour stage and inversely correlated with QoL, which makes it a useful tool to identify patients in need of an early nutritional intervention during oncological treatments.

    In Uruguay, breast cancer incidence is 76.41 per 100.000, and death rate is 25.22 per 100.000. Since 1998, there is a National Programme of breast cancer early detection for females over forty years of age. We studied the state of the mammography facilities throughout the country. There are 657.000 female over forty and 51 mammography X-ray equipment. The Programme includes 2 mammography X-ray equipment in mobile units in the capital and 18 in hospitals all around the country. There are taken 120.000 mammographic exams per year, 15.000 of them belong to women who had participated in the Programme. We found that no mammography facility has established Quality Assurance Programmes. Despite the results of this study showed that is suitable the number and age of the mammography X-ray equipment, the lack of Quality Assurance Programmes will produce, in a short time, a negative cost-benefit balance. The consequences will be serious social, human an economical damages. (author)

    In the 1950s, approximately 20,000 Israeli children received scalp irradiation as treatment for tinea capitis (ringworm of the scalp). To evaluate the necessity and feasibility of early screening of these individuals for thyroid cancer, a small pilot program was undertaken. The examination consisted of a thorough palpation of the thyroid gland and the surrounding area. A sup(99m)Tc thyroid scan and thyroid function tests were performed on individuals in whom palpation suggested a nodular abnormality. A multidisciplinary committee then made a recommendation for or against surgery. A total of 443 persons were screened, and nodular abnormalities of the thyroid were detected in 24 (5.4%). Of these persons, nine displayed symptomatology or reported knowledge of a thyroid condition; despite this, three of them were not receiving treatment. This left 18 subjects - 15 new cases and 3 previously untreated patients - needing follow-up care. Altogether nine persons were recommended for surgery, but one refused. All eight of the excised lesions were benign: four colloid nodules and four adenomas. While the screening program was feasible, the fact that no cancers were detected suggested that in a population exposed to a very low dose of radiation, thyroid screening may not be justified on a large scale.

    Objectives/hypothesis: Sarcomatoid carcinoma of head and neck mucosal sites is a rare malignancy surrounded with much controversy. One factor consistently reported yet not well supported throughout the literature is their relative radioresistance and a general belief that surgery is the treatment of choice. Our objective was to determine if patients treated with radiation for early glottic carcinoma with this histologic diagnosis had worse outcomes than typical squamous cell carcinoma of similar stage. Materials and Methods: Twenty-eight cases of early stage sarcomatoid carcinoma of the larynx treated with definitive doses of megavoltage irradiation between 1969 and 1995 at the University of Texas M.D. Anderson Cancer Center form the cohort for this analysis. All pathologic material was reviewed to confirm the diagnosis. Follow-up ranged from 1.5 - 24 years (median, 10 years). Results: Twenty-one patients were staged T1 and 7 patients had stage T2 disease. Sixteen tumors had the more typical polypoid morphology of sarcomatoid carcinoma. All patients were treated with small laryngeal fields, median size 20 cm2, and to a median dose of 65 Gy. Four patients (14%) had local disease recurrence. All 4 patients had salvage total laryngectomies and remained free of local disease. Only one patient manifested regional and distant disease. The 10-year actuarial survival rate was 63%. Conclusions: Patients with early staged sarcomatoid carcinoma of the glottis treated with radiation had similar control rates to irradiated patients with similar volume disease with the more typical squamous cell carcinoma. We do not believe that the histologic diagnosis of sarcomatoid carcinoma by itself should influence the decision to not treat a patient with early staged glottic disease with irradiation

    We report the case of a male patient, 80 years old, with a history of dyspepsia and no family history of neoplasias. In the upper digestive endoscopy in the distal esophagus, a flat depressed lesion with the appearance of early carcinoma, type IIC of Paris classification, was diagnosed by biopsy as a squamous carcinoma in situ, infiltrating, moderately differentiated non-keratinizing grade II carcinoma. He underwent submucosal endoscopic dissection without complications. Histopathology concluded: carcinoma of squamous cells, predominantly in situ of distal esophagus, measuring 0.6 cm, with focus of 0.1 cm of infiltration in the own lamina; absence of angiolymphatic or perineural invasion. The histopathology specimen had margins of surgical resection free of neoplasia. Stage pT1a. Three months later, in the endoscopy control with biopsy of the area, there was no evidence of carcinoma. We present the case because it is still a challenge to establish the diagnosis of esophageal cancer at an early stage, especially in patients without symptoms, highlighting the importance of chromoendoscopy and a good endoscopic examination to reach the diagnosis. Submucosal endoscopy dissection could be considered as a safe and effective alternative treatment to radical surgery.

    Objective The goal of this study is to determine the effect of primary surgery vs radiotherapy (RT) on overall survival (OS) in patients with early stage oral cavity squamous cell carcinoma (OCSCC). In addition, this study attempts to identify factors associated with receiving primary RT. Study Design Retrospective cohort study. Setting National Cancer Database (NCDB, 2004-2013). Subjects and Methods Reviewing the NCDB from 2004 to 2013, patients with early stage I to II OCSCC were identified. Kaplan-Meier estimates of survival, Cox regression analysis, and propensity score matching were used to examine differences in OS between primary surgery and primary RT. Multivariable logistic regression analysis was performed to identify factors associated with primary RT. Results Of the 20,779 patients included in the study, 95.4% (19,823 patients) underwent primary surgery and 4.6% (956 patients) underwent primary RT. After adjusting for covariates, primary RT was associated with an increased risk of mortality (adjusted hazard ratio [aHR], 1.97; 99% confidence interval [CI], 1.74-2.22). On multivariable analysis, factors associated with primary RT included age ≥70 years, black race, Medicaid or Medicare insurance, no insurance, oral cavity subsite other than tongue, clinical stage II disease, low-volume treatment facilities, and earlier treatment year. Conclusion Primary RT for early stage OCSCC is associated with increased mortality. Approximately 5% of patients receive primary RT; however, this percentage is decreasing. Patients at highest risk for receiving primary RT include those who are elderly, black, with public insurance, and treated at low-volume facilities.

  16. Methylation of Breast Cancer Predisposition Genes in Early-Onset Breast Cancer: Australian Breast Cancer Family Registry.

    Full Text Available DNA methylation can mimic the effects of both germline and somatic mutations for cancer predisposition genes such as BRCA1 and p16INK4a. Constitutional DNA methylation of the BRCA1 promoter has been well described and is associated with an increased risk of early-onset breast cancers that have BRCA1-mutation associated histological features. The role of methylation in the context of other breast cancer predisposition genes has been less well studied and often with conflicting or ambiguous outcomes. We examined the role of methylation in known breast cancer susceptibility genes in breast cancer predisposition and tumor development. We applied the Infinium HumanMethylation450 Beadchip (HM450K array to blood and tumor-derived DNA from 43 women diagnosed with breast cancer before the age of 40 years and measured the methylation profiles across promoter regions of BRCA1, BRCA2, ATM, PALB2, CDH1, TP53, FANCM, CHEK2, MLH1, MSH2, MSH6 and PMS2. Prior genetic testing had demonstrated that these women did not carry a germline mutation in BRCA1, ATM, CHEK2, PALB2, TP53, BRCA2, CDH1 or FANCM. In addition to the BRCA1 promoter region, this work identified regions with variable methylation at multiple breast cancer susceptibility genes including PALB2 and MLH1. Methylation at the region of MLH1 in these breast cancers was not associated with microsatellite instability.

    Body size in early life is inversely associated with adult breast cancer (BC) risk, but it is unclear whether the associations differ by tumor characteristics. In a pooled analysis of two Swedish population-based studies consisting of 6731 invasive BC cases and 28,705 age-matched cancer-free controls, we examined the associations between body size in early life and BC risk. Self-reported body sizes at ages 7 and 18 years were collected by a validated nine-level pictogram (aggregated into three categories: small, medium and large). Odds ratios (OR) and corresponding 95% confidence intervals (CI) were estimated from multivariable logistic regression models in case-control analyses, adjusting for study, age at diagnosis, age at menarche, number of children, hormone replacement therapy, and family history of BC. Body size change between ages 7 and 18 were also examined in relation to BC risk. Case-only analyses were performed to test whether the associations differed by tumor characteristics. Medium or large body size at age 7 and 18 was associated with a statistically significant decreased BC risk compared to small body size (pooled OR (95% CI): comparing large to small, 0.78 (0.70-0.86), P trend <0.001 and 0.72 (0.64-0.80), P trend <0.001, respectively). The majority of the women (~85%) did not change body size categories between age 7 and 18 . Women who remained medium or large between ages 7 and 18 had significantly decreased BC risk compared to those who remained small. A reduction in body size between ages 7 and 18 was also found to be inversely associated with BC risk (0.90 (0.81-1.00)). No significant association was found between body size at age 7 and tumor characteristics. Body size at age 18 was found to be inversely associated with tumor size (P trend  = 0.006), but not estrogen receptor status and lymph node involvement. For all analyses, the overall inferences did not change appreciably after further adjustment for adult body mass index. Our data

    Seven cases of delayed airway stenosis after radiotherapy for early staged head and neck cancers during 1989 and 1999 were evaluated (aged 54-77 yrs, 6 male and a female). The cases included five glottic laryngeal cancers (T1a, T1b, and three T2), a subglottic laryngeal cancer, and an unknown origin, but strongly suspected laryngeal cancer, with neck metastasis. Radio injury was found from 3 months to 47 months after radiotherapy. {sup 60}Co for radiotherapy was used in all seven cases, although {sup 60}Co radionuclide was changed to Liniac in 1997. The total dose was 60 Gy for 3 cases, and 70 Gy for 4 cases. Tracheostomy was performed in 3 cases due to bilateral vocal cord impairment. Background, treatment, and response to radiotherapy were compared to those of 90 patients of a control group with early staged laryngeal cancer who did not fail radiation injury during the same period. As a result, radionuclide ({sup 60}Co), total dose, cervical surgery, antiinflammatory drugs, laryngeal edema during radiotherapy were risk factors. The intensity and the period of mucositis by radiotherapy was important for indicating delayed airway stenosis. (author)

    Following recent improvements in the curability of oral cancer, chronological shifts and changes in the causes of death after treatment have been observed. We conducted a review of the post-treatment causes of death following radiotherapy for oral cancers. The medical records of 966 patients with early-stage (stage I and II) oral cancer treated at our institute between 1980 and 2001 were reviewed, and the chronological shifts and changes in the causes of death after radiotherapy were assessed. Of the 966 patients enrolled in this study, 365 have died to date. Two hundred and eleven patients died of their primary malignancy; 193 of these deaths occurred within 5 years of treatment for the primary oral cancer. The second most frequent cause of death was second primary cancer (n = 90). Twenty-three patients with head and neck cancers and 18 patients with esophageal cancers died within 10 years of radiotherapy, and six patients with lung cancers died after more than 10 years. Within the first 5 years following treatment, the major cause of death was the primary oral cancer. After 5-10 years, a second primary cancer, such as head and neck cancer or esophageal cancer, became the leading cause of death. Over a 10-year period, the proportion of deaths from a second primary cancer in the lung was significant. We have demonstrated that there are chronological shifts and changes in the causes of death following treatment for early-stage oral cancer.

    Cancer patient needs less diagnosis but an effective therapy. The systemic nature of cancer, often right from its inception, requires systemic therapy with cancer-affine radiopharmaceuticals which contain radionuclide species recognizing both the primary and secondary cancers which have generally different biochemical properties. Cancers may be classified into two groups: I. CATIONIC COMPLEX-AFFINE TUMOURS; Lung cancer, thyroid cancer, primary breast cancer, renal cell carcinoma, bone metastases from anionic complex-affine cancers, ...; II. ANIONIC COMPLEX-AFFINE TUMOURS; Primary prostate cancer, melanoma, hepatocellular carcinoma, osteosarcoma, Ewing's sarcoma, bone metastases from cationic complex-affine cancer. With cancer-affine citratogallate-67 complexes we have diagnosed and followed up, and with citratoyttrate-90 complexes we have treated advanced breast, prostate, renal cell cancer patients. The patient preparation by advising to avoid cancer risk factors and to take cancer preventing and radiopharmaceutical stabilizing diets during diagnosis and therapy have given better results. Friendliness, caring visits and telephone calls from the therapist group help to obtain better outcomes of the diagnosis, and mainly of the therapy. The complexes of these radionuclides with other chelating agents EDTA and DPTA are expected to give better images and cure of advanced cancer patients. Cancer-affine formulations of Tc-99m(V), Re-186(V) and Re-188(V)-DMSA are being studied for their future use in early diagnosis and follow-up, and for the systemic therapy of cancer which will show affinity for them.

    The Prevent Cancer Foundation Lung Cancer Workshop XI: Tobacco-Induced Disease: Advances in Policy, Early Detection and Management was held in New York, NY on May 16 and 17, 2014. The two goals of the Workshop were to define strategies to drive innovation in precompetitive quantitative research on the use of imaging to assess new therapies for management of early lung cancer and to discuss a process to implement a national program to provide high quality computed tomography imaging for lung cancer and other tobacco-induced disease. With the central importance of computed tomography imaging for both early detection and volumetric lung cancer assessment, strategic issues around the development of imaging and ensuring its quality are critical to ensure continued progress against this most lethal cancer.

    To analyze the recurrent rate, time of recurrence, type of recurrence and the relationship between recurrence and histopathologic findings after radical gastrectomy for early gastric cancer and evaluate the usefulness of follow up abdominal computed tomography after surgery. We retrospectively evaluated 617 abdominal computed tomographic examinations of 144 patients (101 male, 43 female, mean age, 53 years) who underwent radical subtotal gastrectomy for early gastric cancer between July 1994 and July 1997. Follow-up abdominal CT scans were reviewed by three abdominal radiologists for detection of recurrence of early gastric cancer, and endoscopic and pathologic findings were correlated. We also reviewed the surgical pathologic reports for location, size, cell type and depth of invasion of early gastric cancer and lymph node invasion. We analyzed the recurrent rate, time and type of recurrence, and relationship between recurrence rate and pathologic characteristics of early gastric cancer. The recurrent rate was 4.2% (6/144) during 5-7 years after radical subtotal gastrectomy for early gastric cancer. The recurrence was detected on 2-5 years after operation. The types of recurrence were lymph node metastasis (n=5), liver metastasis (n=4), recurrence in the residual stomach or anastomotic site (n=3), adrenal metastasis (n=1), and lung metastasis (n=1). Relationship between recurrence and location, size, depth of invasion and cell type of early gastric cancer and lymph node metastasis was non significant statistically (p>0.4). The recurrence rate of early gastric cancer after radical subtotal gastrectomy is very low and occurs after two years. The follow up-CT scans can detect all recurrence of early gastric cancer, so regular follow=up abdominal CT examination is useful

    The purpose of this study is to investigate the esophagographic findings of early esophageal cancer (EEC), and to compare these with the pathologic results, and to thus determine the most useful method of esophagography for detection of EEC. We examined 18 patients (M:F=16:2) with pathologically proven EEC; 17 cases were squamous cell carcinoma and one was adenocarcinoma. Tumor size, shape and location were evaluated by esophagography and the findings were compared with the pathologic results. The tumors were 0.5 - 7 cm in size; all except two were smaller than 4 cm. Twelve were located in the middle esophagus, five cases in the lower esophagus and one case in the upper esophagus; in ten cases, the margin was ill-defined. Esophagography showed that eight cases were of the superficial depressed type, seven were the superficial elevated type, and three were the tumorous type. All 18 cases were detected by double contrast study, but mucosal relief study and barium filling study revealed only ten and eight cases, respectively; for the detection of EEC double contrast study was thus the most useful. EEC was commonly demonstrated in the middle esophagus with an ill-defined margin; it was of the superficial depressed or elevated type. For the detection of EEC, double contrast study was the most useful. (author). 14 refs., 1 tab., 5 figs

    Early breast cancer treatment is based on a multimodality approach with the application of clinical and histological prognostic factors to determine locoregional and systemic treatments. The entire scientific community is strongly involved in the management of this disease: radiologists for screening and early diagnosis, gynecologists, surgical oncologists and radiation oncologists for locoregional treatment, pathologists and biologists for personalized characterization, genetic counselors for BRCA mutation history and medical oncologists for systemic therapies. Recently, new biological tools have established various prognostic subsets of breast cancer and developed predictive markers for miscellaneous treatments. The aim of this article is to highlight the contribution of biological tools in the locoregional management of early breast cancer

    Objective: Present the results of the 1995 World Overview which will be held in Oxford England two weeks before ASTRO. Discuss the interpretation and application of these results. Review current research topics on the use of adjuvant endocrine and chemotherapy for early breast cancer. The survival benefits from adjuvant chemotherapy in premenopausal women and adjuvant tamoxifen in postmenopausal women are well established. Each will reduce the annual odds of death by about 25% resulting in a 10 year survival difference of 8-10%. By the time of this presentation, the results of the 1995 Adjuvant Therapy Overview should be with 10+ years of follow-up, and if possible these will be summarized. Current efforts to improve on previous results are focused on the following areas: Optimal chemotherapy dose. Decreasing dose will compromise patient survival. It is not as certain that increasing dose will have as much impact in improving survival. The NSABP was unable to demonstrate an improvement in survival by modestly increasing the dose of cyclophosphamide alone. However, recent results of a Canadian study of CEF (cyclophosphamide, epidoxorubicin, and 5-fluorouracil) and an Intergroup trial of an intense 16 week polychemotherapy program keep alive the possibility that dose escalation is still a very important question. An NSABP trial evaluating even greater cyclophosphamide dose escalation, an Intergroup evaluation of different doxorubicin doses, and two Intergroup trials evaluating very high dose chemotherapy and bone marrow transplantation should provide definitive evidence regarding the importance of dose. Drug sequence. A study from Milan suggests that initial treatment with single agent doxorubicin followed by CMF will be superior to alternating doxorubicin and CMF. This has not been confirmed yet, and the reason for increased benefit from such a sequence is not entirely clear. This concept is being explored further in an Intergroup trial comparing four cycles of

    Full Text Available Background. Nearly 70% of women diagnosed with breast cancer in Ghana are in advanced stages of the disease due especially to low awareness, resulting in limited treatment success and high death rate. With limited epidemiological studies on breast cancer in Ghana, the aim of this study is to assess and understand the pattern of breast cancer distribution for enhancing early detection and treatment. Methods. We randomly selected and screened 3000 women for clinical palpable breast lumps and used univariate and bivariate analysis for description and exploration of variables, respectively, in relation to incidence of breast cancer. Results. We diagnosed 23 (0.76% breast cancer cases out of 194 (6.46% participants with clinically palpable breast lumps. Seventeen out of these 23 (0.56% were premenopausal (<46.6 years with 7 (0.23% being below 35 years. With an overall breast cancer incidence of 0.76% in this study, our observation that about 30% of these cancer cases were below 35 years may indicate a relative possible shift of cancer burden to women in their early thirties in Ghana, compared to Western countries. Conclusion. These results suggest an age adjustment for breast cancer screening to early twenties for Ghanaian women and the need for a nationwide breast cancer screening to understand completely the pattern of breast cancer distribution in Ghana.

    Lymph node metastasis occurs in approximately 10% of early gastric cancer. Preoperative or intra-operative identification of lymph node metastasis in early gastric cancer is crucial for surgical planning. The purpose of this study was to evaluate the feasibility of using carbon nanoparticles to show sentinel lymph nodes (SLNs) in early gastric cancer. A multicenter study was performed between July 2012 and November 2014. Ninety-one patients with early gastric cancer identified by preoperative endoscopic ultrasonography were recruited. One milliliter carbon nanoparticles suspension, which is approved by Chinese Food and Drug Administration, was endoscopically injected into the submucosal layer at four points around the site of the primary tumor 6-12 h before surgery. Laparoscopic radical resection with D2 lymphadenectomy was performed. SLNs were defined as nodes that were black-dyed by carbon nanoparticles in greater omentum and lesser omentum near gastric cancer. Lymph node status and SLNs accuracy were confirmed by pathological analysis. All patients had black-dyed SLNs lying in greater omentum and/or lesser omentum. SLNs were easily found under laparoscopy. The mean number of SLNs was 4 (range 1-9). Carbon nanoparticles were around cancer in specimen. After pathological analysis, 10 patients (10.99%) had lymph node metastasis in 91 patients with early gastric cancer. SLNs were positive in 9 cases and negative in 82 cases. In pathology, carbon nanoparticles were seen in lymphatic vessels, lymphoid sinus, and macrophages in SLNs. When SLNs were positive, cancer cells were seen in lymph nodes. The sensitivity, specificity, and accuracy of black-dyed SLNs in early gastric cancers were 90, 100, and 98.9 %, respectively. No patient had any side effects of carbon nanoparticles in this study. It is feasible to use carbon nanoparticles to show SLNs in early gastric cancer. Carbon nanoparticles suspension is safe for submucosal injection.

  19. Genome-wide association scan for variants associated with early-onset prostate cancer.

    Full Text Available Prostate cancer is the most common non-skin cancer and the second leading cause of cancer related mortality for men in the United States. There is strong empirical and epidemiological evidence supporting a stronger role of genetics in early-onset prostate cancer. We performed a genome-wide association scan for early-onset prostate cancer. Novel aspects of this study include the focus on early-onset disease (defined as men with prostate cancer diagnosed before age 56 years and use of publically available control genotype data from previous genome-wide association studies. We found genome-wide significant (p<5×10(-8 evidence for variants at 8q24 and 11p15 and strong supportive evidence for a number of previously reported loci. We found little evidence for individual or systematic inflated association findings resulting from using public controls, demonstrating the utility of using public control data in large-scale genetic association studies of common variants. Taken together, these results demonstrate the importance of established common genetic variants for early-onset prostate cancer and the power of including early-onset prostate cancer cases in genetic association studies.

    Ovarian cancer is the leading cause of gynecologic cancer mortality, due to the difficulty of early detection. Current screening methods lack sufficient accuracy, and it is still challenging to propose a new early detection method that improves patient outcomes with less-invasiveness. Although many studies have suggested the utility of circulating microRNAs in cancer detection, their potential for early detection remains elusive. Here, we develop novel predictive models using a combination of 8 circulating serum miRNAs. This method was able to successfully distinguish ovarian cancer patients from healthy controls (area under the curve, 0.97; sensitivity, 0.92; and specificity, 0.91) and early-stage ovarian cancer from patients with benign tumors (0.91, 0.86 and 0.83, respectively). This method also enables subtype classification in 4 types of epithelial ovarian cancer. Furthermore, it is found that most of the 8 miRNAs were packaged in extracellular vesicles, including exosomes, derived from ovarian cancer cells, and they were circulating in murine blood stream. The circulating miRNAs described in this study may serve as biomarkers for ovarian cancer patients. Early detection and subtype determination prior to surgery are crucial for clinicians to design an effective treatment strategy for each patient, as is the goal of precision medicine. PMID:29163790

    Few clinical issues have polarized the oncology community as much as screening for prostate cancer, with advocates of prostate-specific antigen (PSA) testing vocal on one side and skeptics just as vocal on the other. At the NCCN 19th Annual Conference, Dr. Peter R. Carroll and Dr. Andrew J. Vickers tackled the controversy surrounding early detection of prostate cancer, focusing attention on the randomized trial results at the heart of the matter; over-detection (the Achilles' heel of screening); and the rationale behind the new, streamlined 2014 NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Prostate Cancer Early Detection, which emphasize selective early detection and treatment and are tightly aligned with the NCCN Guidelines for Prostate Cancer.

    To determine whether triple negative (TN) early stage breast cancers have poorer survival rates compared with other molecular types. Between August 2000 and July 2006, patients diagnosed with stage I, II early stage breast cancers, in whom all three markers (estrogen receptor, progesterone receptor, and human epidermal growth factor receptor [HER]-2) were available and treated with modified radical mastectomy or breast conserving surgery followed by radiotherapy, were retrospectively reviewed. Of 446 patients, 94 (21.1%) were classified as TN, 57 (12.8%) as HER-2 type, and 295 (66.1%) as luminal. TN was more frequently associated with young patients younger than 35 years old (p = 0.002), higher histologic grade (p 0.05). We found that patients with TN early stage breast cancers had no difference in survival rates compared with other molecular subtypes. Prospective study in homogeneous treatment group will need for a prognosis of TN early stage breast cancer.

    Although recent trends in laparoscopic procedures have been toward minimizing the number of incisions, four or five ports are normally required to complete laparoscopic gastrectomy because of the complexity of this procedure. Multi-channel ports, such as the SILS port (Covidien, JAPAN), are now available and are crucial for performing single-incision laparoscopic surgery (SILS) or reduced port surgery (RPS). We carried out reduced port distal gastrectomy (RPDG) using a dual-port method with a SILS port. Ten patients who were diagnosed as early stage gastric cancer were offered the RPDG. Mean age and body mass index (BMI) were 68.1 and 21.4, respectively. No distant metastasis or regional lymph node swelling was seen in any case. A 5-mm flexible scope (Olympus, JAPAN) and SILS port were used and a nylon ligature with a straight needle, instead of a surgical instrument, was available to raise the gastric wall. The average operative time was 266.9 ± 38.3 min and blood loss was 37.8 ± 56.8 ml. Patients recovered well and experienced no complications after surgery. All patients could tolerate soft meals on the first day after surgery and the average hospital stay was 8.1 days. Past conventional LAG cases were evaluated to compare the short-term outcome and no difference was seen in the mean operative time or operative blood loss. The length of hospital stay after surgery was shorter for the RPDG group than the conventional operation group (p < 0.0001). Interestingly, the trend of serum CRP elevation after surgery was lower in the RPDG group than the conventional LAG group (p = 0.053). Although the benefits of RPS have not been established, this type of surgery may be expected to have some advantages. Cosmetic benefits and shorter hospital stays are clear advantages. Less invasiveness can be expected according to the trend of serum CRP elevation after RPDG.

    Abstract Although endoscopic ultrasonography (EUS) is the first-choice imaging modality for predicting the invasion depth of early gastric cancer (EGC), the prediction accuracy of EUS is significantly decreased when EGC is combined with ulceration. The aim of present study was to compare the accuracy of EUS and conventional endoscopy (CE) for determining the depth of EGC. In addition, the various clinic-pathologic factors affecting the diagnostic accuracy of EUS, with a particular focus on endoscopic ulcer shapes, were evaluated. We retrospectively reviewed data from 236 consecutive patients with ulcerative EGC. All patients underwent EUS for estimating tumor invasion depth, followed by either curative surgery or endoscopic treatment. The diagnostic accuracy of EUS and CE was evaluated by comparing the final histologic result of resected specimen. The correlation between accuracy of EUS and characteristics of EGC (tumor size, histology, location in stomach, tumor invasion depth, and endoscopic ulcer shapes) was analyzed. Endoscopic ulcer shapes were classified into 3 groups: definite ulcer, superficial ulcer, and ill-defined ulcer. The overall accuracy of EUS and CE for predicting the invasion depth in ulcerative EGC was 68.6% and 55.5%, respectively. Of the 236 patients, 36 patients were classified as definite ulcers, 98 were superficial ulcers, and 102 were ill-defined ulcers, In univariate analysis, EUS accuracy was associated with invasion depth (P = 0.023), tumor size (P = 0.034), and endoscopic ulcer shapes (P = 0.001). In multivariate analysis, there is a significant association between superficial ulcer in CE and EUS accuracy (odds ratio: 2.977; 95% confidence interval: 1.255–7.064; P = 0.013). The accuracy of EUS for determining tumor invasion depth in ulcerative EGC was superior to that of CE. In addition, ulcer shape was an important factor that affected EUS accuracy. PMID:27472672

    Breast cancer is worldwide the second most common type of cancer after lung cancer. Traditional mammography and Tissue Microarray has been studied for early cancer detection and cancer prediction. However, there is a need for more reliable diagnostic tools for early detection of breast cancer. This can be a challenge due to a number of factors and logistics. First, obtaining tissue biopsies can be difficult. Second, mammography may not detect small tumors, and is often unsatisfactory for younger women who typically have dense breast tissue. Lastly, breast cancer is not a single homogeneous disease but consists of multiple disease states, each arising from a distinct molecular mechanism and having a distinct clinical progression path which makes the disease difficult to detect and predict in early stages. In the paper, we present a Support Vector Machine based on Recursive Feature Elimination and Cross Validation (SVM-RFE-CV) algorithm for early detection of breast cancer in peripheral blood and show how to use SVM-RFE-CV to model the classification and prediction problem of early detection of breast cancer in peripheral blood.The training set which consists of 32 health and 33 cancer samples and the testing set consisting of 31 health and 34 cancer samples were randomly separated from a dataset of peripheral blood of breast cancer that is downloaded from Gene Express Omnibus. First, we identified the 42 differentially expressed biomarkers between "normal" and "cancer". Then, with the SVM-RFE-CV we extracted 15 biomarkers that yield zero cross validation score. Lastly, we compared the classification and prediction performance of SVM-RFE-CV with that of SVM and SVM Recursive Feature Elimination (SVM-RFE). We found that 1) the SVM-RFE-CV is suitable for analyzing noisy high-throughput microarray data, 2) it outperforms SVM-RFE in the robustness to noise and in the ability to recover informative features, and 3) it can improve the prediction performance (Area Under

    As an organized screening program, the national Breast and Cervical Cancer Early Detection Program (BCCEDP) was launched in the early 1990s to improve breast cancer outcomes among underserved women. To analyze the impact of the BCCEDP on breast cancer outcomes in Ohio, this study compared cancer stages and mortality across BCCEDP participants, Medicaid beneficiaries, and "all others." This study linked data across the Ohio Cancer Incidence Surveillance System, Medicaid, the BCCEDP database, death certificates, and the US Census and identified 26,426 women aged 40 to 64 years who had been diagnosed with incident invasive breast cancer during the years 2002-2008 (deaths through 2010). The study groups were as follows: BCCEDP participants (1-time or repeat users), Medicaid beneficiaries (women enrolled in Medicaid before their cancer diagnosis [Medicaid/prediagnosis] or around the time of their cancer diagnosis [Medicaid/peridiagnosis]), and all others (women identified as neither BCCEDP participants nor Medicaid beneficiaries). The outcomes included advanced-stage cancer at diagnosis and mortality. A multivariable logistic and survival analysis was conducted to examine the independent association between the BCCEDP and Medicaid status and the outcomes. The percentage of women presenting with advanced-stage disease was highest among women in the Medicaid/peridiagnosis group (63.4%) and lowest among BCCEDP repeat users (38.6%). With adjustments for potential confounders and even in comparison with Medicaid/prediagnosis beneficiaries, those in the Medicaid/peridiagnosis group were twice as likely to be diagnosed with advanced-stage disease (adjusted odds ratio, 2.20; 95% confidence interval, 1.83-2.66). Medicaid/peridiagnosis women are at particularly high risk to be diagnosed with advanced-stage disease. Efforts to reduce breast cancer disparities must target this group of women before they present to Medicaid. Cancer 2017;123:3097-106. © 2017 American Cancer Society

    Occurrence of metastatic cancer to the stomach is rare, particularly in patients with prostate cancer. Gastric metastasis generally presents as a solitary and submucosal lesion with a central depression. We describe a case of gastric metastasis arising from prostate cancer, which is almost indistinguishable from the undifferentiated-type gastric cancer. A definitive diagnosis was not made until endoscopic resection. On performing both conventional and magnifying endoscopies, the lesion appeared to be slightly depressed and discolored area and it could not be distinguished from undifferentiated early gastric cancer. Biopsy from the lesion was negative for immunohistochemical staining of prostate-specific antigen, a sensitive and specific marker for prostate cancer. Thus, false initial diagnosis of an early primary gastric cancer was made and endoscopic submucosal dissection was performed. Pathological findings from the resected specimen aroused suspicion of a metastatic lesion. Consequently, immunostaining was performed. The lesion was positive for prostate-specific acid phosphatase and negative for prostate-specific antigen, cytokeratin 7, and cytokeratin 20. Accordingly, the final diagnosis was a metastatic gastric lesion originating from prostate cancer. In this patient, the definitive diagnosis as a metastatic lesion was difficult due to its unusual endoscopic appearance and the negative stain for prostate-specific antigen. We postulate that both of these are consequences of hormonal therapy against prostate cancer.

    Geographic barriers and limited availability of cancer specialists may influence early prostate cancer treatment options for rural men. This study compares receipt of different early prostate cancer treatments between rural and urban patients. Using 2004-2006 SEER Limited-Use Data, 51,982 early prostate cancer patients were identified (T1c, T2a, T2b, T2c, T2NOS; no metastases) who were most likely to benefit from definitive treatment (rural-urban residence overall, and for different sociodemographic and cancer characteristics, and different states based on logistic regression analyses, using general estimating equation methods to account for clustering by county. Adjusted definitive treatment rates were lower for rural (83.7%) than urban (87.1%) patients with early-stage prostate cancer (P ≤ .01). Rural men were more likely than urban men to receive non-definitive surgical treatment and no initial treatment. The lowest definitive treatment rates were among rural subgroups: 70 to 74 years (73.9%), African Americans (75.6%), American Indians/Alaska Natives (77.8%), single/separated/divorced (76.8%), living in New Mexico (69.3%), and living in counties with persistent poverty (79.6%). Between 2004 and 2006, this adjusted analysis found that men who were living in rural areas were less likely to receive definitive treatment for their early-stage prostate cancer than those living in urban areas. Certain rural patient groups with prostate cancer need particular attention to ensure their access to appropriate treatment. Rural providers, rural health care systems, and cancer advocacy and support organizations should ensure resources are in place so that the most vulnerable rural groups (men between 60 and 74 years of age; African American men; men who are single, separated, or divorced; and men living in rural New Mexico) can make informed prostate cancer treatment choices based on their preferences.

    This study presents a method to identify early esophageal cancer within endoscope using hyperspectral imaging technology. The research samples are three kinds of endoscopic images including white light endoscopic, chromoendoscopic, and narrow-band endoscopic images with different stages of pathological changes (normal, dysplasia, dysplasia - esophageal cancer, and esophageal cancer). Research is divided into two parts: first, we analysis the reflectance spectra of endoscopic images with different stages to know the spectral responses by pathological changes. Second, we identified early cancerous lesion of esophagus by principal component analysis (PCA) of the reflectance spectra of endoscopic images. The results of this study show that the identification of early cancerous lesion is possible achieve from three kinds of images. In which the spectral characteristics of NBI endoscopy images of a gray area than those without the existence of the problem the first two, and the trend is very clear. Therefore, if simply to reflect differences in the degree of spectral identification, chromoendoscopic images are suitable samples. The best identification of early esophageal cancer is using the NBI endoscopic images. Based on the results, the use of hyperspectral imaging technology in the early endoscopic esophageal cancer lesion image recognition helps clinicians quickly diagnose. We hope for the future to have a relatively large amount of endoscopic image by establishing a hyperspectral imaging database system developed in this study, so the clinician can take this repository more efficiently preliminary diagnosis.

    Full Text Available BACKGROUND: Metabolic syndrome and/or its components have been demonstrated to be risk factors for several cancers. They are also found to influence survival in breast, colon and prostate cancer, but the prognostic value of metabolic syndrome in gastric cancer has not been investigated. METHODS: Clinical data and pre-treatment information of metabolic syndrome of 587 patients diagnosed with early stage gastric cancer were retrospectively collected. The associations of metabolic syndrome and/or its components with clinical characteristics and overall survival in early stage gastric cancer were analyzed. RESULTS: Metabolic syndrome was identified to be associated with a higher tumor cell differentiation (P=0.036. Metabolic syndrome was also demonstrated to be a significant and independent predictor for better survival in patients aged >50 years old (P=0.009 in multivariate analysis or patients with proximal gastric cancer (P=0.047 in multivariate analysis. No association was found between single metabolic syndrome component and overall survival in early stage gastric cancer. In addition, patients with hypertension might have a trend of better survival through a good control of blood pressure (P=0.052 in univariate analysis. CONCLUSIONS: Metabolic syndrome was associated with a better tumor cell differentiation in patients with early stage gastric cancer. Moreover, metabolic syndrome was a significant and independent predictor for better survival in patients with old age or proximal tumors.

    2001-01-01

    The relationship of breast cancer to early reproductive development and height suggests that fetal and childhood nutrition may be important in its aetiology. Caloric restriction sufficient to reduce adult height may reduce breast cancer risk. During World War II (WWII) there was a marked reduction in average caloric intake in Norway that resulted in greater nutritional diversity. We hypothesized that a positive association between height and risk of breast cancer would be stronger among women...

    1995-01-01

    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.

    In its early stage, cancer of the larynx is treated mainly by irradiation. A clinical and histological study of the radiation-resistant cancer of the larynx is reported. From 1958 to 1976, 1190 patients with squamous cell carcinoma of the larynx were treated at the Department of Otolaryngology, Osaka University Hospital. Among them, 597 patients (50.2%) were treated by radiation therapy. In 180 patients who had developed local recurrence after initial irradiation, partial or total laryngectomies were performed and 5-year crude survival rates were 71.3%. Gross examination of the specimens and histological studies were performed on these cases, as well as microangiography. The majority of recurrent glottic cancers were located at the anterior commissure and had some subglottic extention. In the supraglottic cancers, marked invasion to the pre-epiglottic space, perichondritis, and edema of the arytenoids were observed. These findings suggested that the unsuccessful radiation therapy was due to the diagnostic failure of the tumor extention. Fixation of the affected vocal cords and ulcer formation were also observed. Histologically, cancer cells invaded deeply the surrounding tissues as scattered cancer nests with marked hypoxic stromal reaction. This study suggests that radiation therapy should be the initial but non-repetitive treatment of choice for earlystage laryngeal cancers.

    The results were analyzed of 175 patients with glottic squamous cell carcinomas who were treated with curative purposes (1970-1986). Overall 10-year local control rates were 74% for the surgical series and 69% for the cases treated by radiation therapy. After salvage therapy 10-year survival rates were 83% and 76% respectively. The analysis of the results showed no statistically significant difference. In the group treated by radical surgery 80% local control was observed, versus 66% in the cases treated with conservative surgery. 10-year survival rate was higher in the latter group (89% versus 81%) because of better results of salvage therapy: 7 of 10 recurrences were salvaged with the second treatment. Several prognostic factors were evaluated-i.e., T extent, anterior commissure involvement, subglottic invasion, vocal cord mobility impairment, and ventricular involvement. Anterior commissure involvement was the main factor affecting out-come in the surgical series: in the presence of this factor, 64% 10-year local control was observed versus 85% in the patients without commissure involvement. This factor proved more important in the patients treated with conservative surgery (10-year control: 42 versus 88%) than in those undergoing radical surgery (78% versus 85%). Anterior commissure involvement and the number of involved subsites were found to worsen prognosis in the serial treated by radiation therapy: cases with anterior commissure involvement had 59% 10-year local control versus 83%. The cases with a deeper spread had 60% local control versus 75%. Vocal cord mobility impairment was a less important prognosis factor in both series. Our results suggest radiation therapy as a valuable method in a treatment of the small T2 laryngeal cancers which are not suitable for conservative surgery

    The results of a mammography screening programme launched by the American Cancer Society and the National Cancer Institute are discussed. Twenty-seven Breast Cancer Detection Demonstration Projects (BCDDP) screened 280,000 women annually for 5 years. During the first 2 screenings, 1810 cancers were detected. An increased rate of discovery in all age groups was achieved. The radiation risk of mammography is also discussed. The results of the BCDDP were evaluated by a review panel. Of the 1810 cancers detected, 45% had been detected by mammography alone, 47% by mammography and physical examination and only 7% by physical examination alone. 592 of the cancers were < 1 cm in diameter. Two-thirds of these lesions were considered to be in-situ carcinoma and one-third invasive cancer. In 66 instances, the tissue first presented was considered not to be cancerous; these cases were further studied clinically and pathologically. It is concluded that, in the experience of the BCDDP, mammography proved to be an excellent method of detection, but it does have a small theoretical risk. As a widely used approach to detection, mammography is probably not practical due to the number of experts necessary for image evaluation. (UK)

    Endometrial cancer is the most frequent cancer of female genital tract. Metro- and menorrhagia or postmenopausal bleeding results in its early presentation. It allows radical treatment. However, controversies remain on surgery coverage or adjuvant therapies in early endometrial women cancer. Optimal management should minimize intervention instead of aggressive approach, as showed by recent studies. There is a role for brachytherapy as an adjuvant irradiation. Crucial publications including PORTEC-1, GOG 99, MRC ASTEC, ASTEC/EN.5, PORTEC-2 or Italian lymphadenectomy trial are discussed. Moreover, there is attention paid on adjuvant vaginal brachytherapy analyses for the past fifteen years.

    The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides breast and cervical cancer screening and diagnostic services to low-income and underserved women through a network of providers and health care organizations. Although the program serves women 40-64 years old for breast cancer screening and 21-64 years old for cervical cancer screening, the priority populations are women 50-64 years old for breast cancer and women who have never or rarely been screened for cervical cancer. From 1991 through 2011, the NBCCEDP provided screening and diagnostic services to more than 4.3 million women, diagnosing 54,276 breast cancers, 2554 cervical cancers, and 123,563 precancerous cervical lesions. A critical component of providing screening services is to ensure that all women with abnormal screening results receive appropriate and timely diagnostic evaluations. Case management is provided to assist women with overcoming barriers that would delay or prevent follow-up care. Women diagnosed with cancer receive treatment through the states' Breast and Cervical Cancer Treatment Programs (a special waiver for Medicaid) if they are eligible. The NBCCEDP has performance measures that serve as benchmarks to monitor the completeness and timeliness of care. More than 90% of the women receive complete diagnostic care and initiate treatment less than 30 days from the time of their diagnosis. Provision of effective screening and diagnostic services depends on effective program management, networks of providers throughout the community, and the use of evidence-based knowledge, procedures, and technologies.

    Choroidal metastasis from colorectal cancer is rare, and there have been no reported cases of such metastasis from early colorectal cancer. We report a case of choroidal metastasis from early rectal cancer. A 61 year-old-man experienced myodesopsia in the left eye 2 years and 6 months after primary rectal surgery for early cancer, and was diagnosed with left choroidal metastasis and multiple lung metastases. Radiotherapy was initiated for the left eye and systemic chemotherapy is initiated for the multiple lung metastases. The patient is living 2 years and 3 months after the diagnosis of choroidal metastasis without signs of recurrence in the left eye, and continues to receive systemic chemotherapy for multiple lung metastases. Current literatures have few recommendations regarding the appropriate treatment of choroidal metastasis from colorectal cancer, but an aggressive multi-disciplinary approach may be effective in local regression. This is the first report of choroidal metastasis from early rectal cancer. We consider it important to enforce systemic chemotherapy in addition to radiotherapy for choroidal metastasis from colorectal cancer. Copyright © 2014 The Authors. Published by Elsevier Ltd..

    To evaluate the long-term results of exclusive chemotherapy for T1-T3N0M0 glottic squamous cell carcinoma complete clinical responders after induction chemotherapy. Between 1985 and 2000, 69 patients with glottic squamous cell carcinoma complete clinical responders after induction chemotherapy were managed with exclusive chemotherapy at our department. Chemotherapy associated platinum and fluorouracil. This retrospective analysis evaluated actuarial survival, treatment morbidity, oncologic events and laryngeal preservation. Various independent factors were tested for potential correlation with survival and local recurrence. The 5-year Kaplan-Meier actuarial survival, local control, lymph node control estimate were 83,6%, 64,8%, 98,6% respectively. Chemotherapy never resulted in death. The 10-year actuarial metachronous second primary tumors estimate was 32%. The overall laryngeal preservation rate was 98,6%. Altogether our data and the review of the literature suggest that in patients achieving a complete clinical response after and induction based chemotherapy regimen, the completion of an exclusive chemotherapy regimen appears to be a valid alternative to the conventional use of radiotherapy or chemo-radiation protocols.

    The purpose of this study was to determine the prognostic factors affecting local outcomes for patients with T2N0 glottic carcinoma treated by definitive radiotherapy. A total of 48 patients with T2N0 squamous cell carcinoma treated by definitive radiotherapy between 1992 and 2005 were studied. Cumulative probability of overall survival, cause-specific survival, local control and larynx-preserving were calculated according the Kaplan-Meier method, and the prognostic significance of patient's age, number of subsites involved, impaired cord mobility, anterior commisure involved, total dose and overall treatment time were analyzed using the log-rank test in univariate analysis and Cox regression in multivariate analysis. Follow-up ranged from 13 to 141 months (median, 62 months). Five-year survivals were: overall, 95.3%; cause-specific, 97.9% and five years rates were local control, 61.4%; larynx-preserving, 76.4%. Multivariate analyses of the six parameters showed that overall treatment time significantly influenced the probability of local control, and impaired mobility and overall treatment time affected the probability of larynx-preserving. Our study showed that longer overall treatment time significantly worsened the percentage of local control and larynx-preserving for patients with T2N0 glottic carcinoma treated with definitive radiotherapy. Therefore, we suggest treating, the patients in a shorter treatment course. (author)

    Oral cancer is the 11th most common cancer worldwide, especially in a male adult. The median age of death in oral cancer was 55 years, 10-20 years earlier than other cancers. Presently, oral cancer is often found in late stage, because the lesion is often flat in early stage and is difficult to diagnose under traditional white light imaging. The only definitive method for determining cancer is an invasive biopsy and then using histology examination. How to detect precancerous lesions or early malignant lesions is an important issue for improving prognosis of oral cancer. Optical coherence tomography (OCT) is a new optical tool for diagnosing early malignant lesions in the skin or gastrointestinal tract recently. Here we report a new method for detecting precancerous or early malignant oral lesions by using swept source polarization-sensitive optical coherence tomography (PS-OCT) with center-wavelength 1310 nm, bandwidth 110 nm and 100 kHz swept rate. We used all single-mode fiber design to detect the change of birefringence information in the epithelium structure. This system has an advantage that enables measurement of backscattered intensity and birefringence simultaneously with only one A-scan per transverse location. In preliminary result, we computed the slope of the every A-scan signal in tissue part using a linear-curve fitting in backscattered intensity and birefringence on the enface. In this research, we used an oral cancer mice model for observing the change of structure and birefringence properties in different stages of oral cancer mice. We presented the parametric enface imaging that can detect the early oral malignant lesions.

    To investigate levels of TSGF,CA125 and CEA as a panel for early diagnosis of overian cancer, the levels of three tumor markers(TSGF,CA125 and CEA) in serum were determined in 85 patients with ovarian cancer, 54 patients with benign tumor and 76 healthy control. The results showed that the levels of three tumor markers in ovarian cancer patients were significantly higher than those in benign tumor patients and controls(P<0.05). Combined detection of the three markers may greatly improve the diagnostic accuracy of overian cancer. (authors)

    Screening of prostate cancer with PSA is a challenge for the aid to decision. Beside the rather mediocre characteristics of the screening test, there the additional problem of the peculiar biology of this cancer, with its late development and its ability to remain latent for a prolonged period. On the other hand, the treatment (surgery, irradiation) is associated with important side-effects: impotence and urinary leakage. Several studies, which appear to be a form of aid to information than aid to shared decision, have been carried out to analyse the effect of various modes of information on the behaviour of potential candidates to screening of prostate cancer, with the following results: better knowledge of the problem, lower rate of acceptance of PSA testing and trend towards watchful waiting rather than surgery in case of discovery of cancer.

    Breast cancer is the most common type of cancer in women throughout the world. However, in comparison with Western women, it presents relatively early in women of Asian ethnicity. Early menarche, late menopause, use of OCP's, family history of benign or malignant breast disease, exposure to radiation and BMI in the under-weight range are well known risk factors for the development of breast cancer in premenopausal women. Early detection with the use of breast self-examination (BSE) and breast cancer screening programs can lead to a reduction in the mortality rates due to breast cancer. The aim of our study was to assess the risk factors for breast cancer among young women and to emphasize the importance of early screening among them. We conducted a cross-sectional study among women aged 18 to 25 using a self- administered questionnaire. Data was collected over a period of 6 months from June to December, 2014. A total of 300 young women selected randomly from Dow Medical College and various departments of Karachi University successfully completed the survey. Respondents were 18-25 years of age (mean age=21.5). Out of the 300 young females, 90 (30%) had at least one risk factor, 90 (30%) had two, 40 (13%) had three, 8 (2.7%) had four, 2 (0.7%) had five while one female was found to have six positive risk factors for breast cancer. Some 66 women (22%) experienced symptoms of breast cancer such as non-cyclical pain and lumps. While 222 women (74%) had never performed breast self-examination, 22 (7.3%) had had a breast examination done by a health professional while 32 (10.7%) had participated in breast screening programs. A total of 223 (74.3%) women considered breast cancer screening important for young women. The percentage of young women with risk factors for breast cancer was found to be alarmingly high. Therefore, screening for breast cancer should start at an early age especially in high risk groups. Awareness about breast self-examination should be emphasized

    A diagnosis of pancreatic cancer is devastating owing to its poor prognosis, with a 5-year survival rate of only 9%. Currently, most individuals are diagnosed at a late stage when treatment options are limited. Early detection of pancreatic cancer provides the greatest hope for making substantial improvements in survival. The Kenner Family Research Fund in partnership with the American Pancreatic Association has sponsored a series of fora to stimulate discussion and collaboration on early detection of pancreatic cancer. At the first forum in 2014, "Early Detection of Sporadic Pancreatic Cancer Summit Conference," a strategic plan was set forth by an international group of interdisciplinary scientific representatives and subsequently The Strategic Map for Innovation was generated. The current conference report is the third forum in the series, "Early Detection of Pancreatic Cancer: The Role of Industry in the Development of Biomarkers," which was held in Boston, Massachusetts, on October 27, 2016. This report provides an overview of examples of innovative initiatives by industry and confirms the critical need for collaboration among industry, government, research institutions, and advocacy groups in order to make pancreatic cancer more easily detectable in its earlier stages, when it is more treatable.

    Early cancer (high-grade dysplasia [HGD] and intramucosal carcinoma [ImCa]) associated with Barrett's esophagus (BE) may have a circumferential spatial predilection. To describe the esophageal circumferential location of early cancer in BE. Retrospective study, single tertiary referral center. One hundred nineteen patients were referred for endoscopic eradication therapy for early cancer associated with BE. Endoscopic images and reports and pathology were reviewed. Circumferential location designation of early cancer in BE by using a clock-face orientation. One hundred nineteen of 131 patients referred for endoscopic eradication therapy had a location designation for their advanced histology (91.9%). There were a total of 57 patients (47.9%) with HGD and 62 patients (52.1%) with ImCa. There was a significantly higher rate of early cancer (HGD or ImCa) in the right hemisphere (12 to 6 o'clock location) compared with the left hemisphere (84.9% vs 15.1%, P cancer was found in the 12 to 3 o'clock quadrant (64.7%); 71.9% of HGD and 58.1% of ImCa lesions were located in the 12 to 3 o'clock quadrant. Retrospective design, single center. Early cancer associated with BE is far more commonly found in the right hemisphere of the esophagus (12 to 6 o'clock) with the highest rate in the 12 to 3 o'clock quadrant. These findings support enhanced scrutiny of the right hemisphere of the esophagus during surveillance and endoscopic treatment of patients with BE.

    2006-01-01

    Background. Overall bad prognosis of lung cancer is mostly due to too late detection of early lung cancer, which may be treated with good success. Therefore, different diagnostic methods are developing for more efficient detection of early lung cancer: besides modern radiological, bronchoscopic methods with additional fluorescence techniques, quantitative cytological investigations, also histological and molecular investigations are included. Histology may reveal early preinvasive lung cancer lesions, associated early during multistep lung carcinogenesis with molecular genetic changes. Patients and methods. Preinvasive epithelial lung cancer lesions we searched in two groups of patients. In the first group of 316 patients from the period March 2003 - August 2006, 498 bronchial and transbronchial biopsies were examined for squamous metaplasia and dysplasia, carcinoma in situ, and invasive tumours. In the second group of 238 patients from the period January 2004 - August 2006, resected primary lung tumours were analysed for preinvasive and invasive neuroendocrine tumours and atypical adenomatous hyperplasia. Results. The most frequent changes in bronchial and transbronchial biopsies were squamous metaplasia (46.5%), simple or goblet cell hyperplasia of the bronchial epithelium (44.3%), malignant tumours (20.66%) and squamous dysplasia (16.1%), but rare carcinoma in situ (0.63%). Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia was found in 15 (6.3%) cases in the vicinity of 238 resected lung cancer specimens, carcinoid in 12 patients (5%), and mostly combined large cell neuroendocrine cancer in 21 patients (8.8%). Atypical adenomatous hyperplasia was found in 2 patients. Conclusions. Classical histological analysis should be focused on detection of early preinvasive epithelial lung cancer lesions. Additional available molecular investigations may reveal gradual genetic changes characteristic for a series of the preinvasive epithelial histological changes

  11. Computer-aided detection of early cancer in the esophagus using HD endoscopy images

    Esophageal cancer is the fastest rising type of cancer in the Western world. The recent development of High-Definition (HD) endoscopy has enabled the specialist physician to identify cancer at an early stage. Nevertheless, it still requires considerable effort and training to be able to recognize these irregularities associated with early cancer. As a first step towards a Computer-Aided Detection (CAD) system that supports the physician in finding these early stages of cancer, we propose an algorithm that is able to identify irregularities in the esophagus automatically, based on HD endoscopic images. The concept employs tile-based processing, so our system is not only able to identify that an endoscopic image contains early cancer, but it can also locate it. The identification is based on the following steps: (1) preprocessing, (2) feature extraction with dimensionality reduction, (3) classification. We evaluate the detection performance in RGB, HSI and YCbCr color space using the Color Histogram (CH) and Gabor features and we compare with other well-known features to describe texture. For classification, we employ a Support Vector Machine (SVM) and evaluate its performance using different parameters and kernel functions. In experiments, our system achieves a classification accuracy of 95.9% on 50×50 pixel tiles of tumorous and normal tissue and reaches an Area Under the Curve (AUC) of 0.990. In 22 clinical examples our algorithm was able to identify all (pre-)cancerous regions and annotate those regions reasonably well. The experimental and clinical validation are considered promising for a CAD system that supports the physician in finding early stage cancer.

    Compared with careful attention to the physical (eg, urinary, bowel, sexual) dysfunction that may follow treatment, little attention has been given to the behavioral, emotional, and interpersonal changes that the diagnosis of early prostate cancer and subsequent physical dysfunction may bring. To construct patient-centered measures of the outcomes of treatment for early prostate cancer. Qualitative study followed by survey of early prostate cancer patients and group of comparable patients with no history of prostate cancer. Analysis of focus groups identified relevant domains of quality of life, which were represented by Likert scale items included in survey questionnaires. Psychometric analyses of survey data defined scales evaluated with respect to internal consistency and validity. Qualitative analysis identified three domains: urinary control, sexuality, and uncertainty about the cancer and its treatment. Psychometric analysis defined 11 scales. Seven were generically relevant to most older men: urinary control (eg, embarrassment with leakage), sexual intimacy (eg, anxiety about completing intercourse), sexual confidence (eg, comfort with sexuality), marital affection (eg, emotional distance from spouse/partner), masculine self esteem (eg, feeling oneself a whole man), health worry (eg, apprehensiveness about health changes), and PSA concern (eg, closely attending to one's PSA). Four scales were specific to the treatment experience: perceived cancer control, quality of treatment decision making, regret of treatment choice, and cancer-related outlook. The scales provide definition and metrics for patient-centered research in this area. They complement measures of physical dysfunction and bring into resolution outcomes of treatment that have gone unnoticed in previous studies.

    Lung cancer is the leading cause of cancer deaths, with an overall survival of 15% at five years. Biomarkers that can sensitively and specifically detect lung cancer at early stage are crucial for improving this poor survival rate. Sputum has been the target for the discovery of non-invasive biomarkers for lung cancer because it contains airway epithelial cells, and molecular alterations identified in sputum are most likely to reflect tumor-associated changes or field cancerization caused by smoking in the lung. Sputum-based molecular biomarkers include morphology, allelic imbalance, promoter hypermethylation, gene mutations and, recently, differential miRNA expression. To improve the sensitivity and reproducibility of sputum-based biomarkers, we recommend standardization of processing protocols, bronchial epithelial cell enrichment, and identification of field cancerization biomarkers.

    Adolescence is a highly susceptible period for mammary carcinogenesis, but few prospective studies have examined the role of adolescent diet in breast cancer risk. Reduced rank regression has previously been used to identify a dietary pattern associated with markers of inflammation (C-reactive protein, IL6, and TNFα receptor 2). We investigated whether an adolescent and early adulthood inflammatory dietary pattern was associated with breast cancer among 45,204 women in the Nurses' Health Study II using reduced rank regression. Participants completed a food frequency questionnaire in 1998 about their high school diet (HS-FFQ) and a FFQ in 1991 when they were ages 27-44 years. Among women who completed the HS-FFQ, 1,477 cases of breast cancer were diagnosed during 22 years of follow-up. An adolescent and early adulthood dietary pattern characterized by inflammation was associated with an increased incidence of premenopausal but not postmenopausal breast cancer. Women in the fifth quintile of the inflammatory pattern score had multivariable adjusted HRs for premenopausal breast cancer of 1.35 for adolescent diet [95% confidence interval (95% CI), 1.06-1.73; P trend = 0.002] and 1.41 for early adulthood diet (95% CI, 1.11-1.78; P trend = 0.006) compared with women in the first quintile. The corresponding RRs for postmenopausal breast cancer were 0.84 (95% CI, 0.60-1.17) for adolescent and 0.76 (95% CI, 0.54-1.06) for adult intake. Overall, our findings support the notion that an adolescent and early adulthood diet characterized by high intake of sugar-sweetened and diet soft drinks, refined grains, red and processed meat, and margarine, and low intake of green leafy vegetables, cruciferous vegetables, and coffee may increase the incidence of premenopausal breast cancer.

    This longitudinal study was designed to assess patients' desire for early retirement and investigate which cancer-related and psychosocial characteristics are associated with early retirement. We assessed 750 cancer patients at the beginning (t 0 ) and end (t 1 ) of, and 12 months after (t 2 ) inpatient cancer rehabilitation. At t 0 , 22% had a desire to retire early. These patients reported significantly longer sick leave periods, less favourable workplace environments, lower work ability, higher psychological distress and lower quality of life than other patients. At t 2 , 12.5% of patients received temporary or permanent early retirement pensions. Of all patients with a desire for early retirement at t 0 , 43% had returned to work at t 2 . This subgroup had a significantly lower physical quality of life than other patients returning to work. The most influential predictors of early retirement were being on sick leave (OR = 6.50, 95% CI = 1.97-21.47) and a desire for early retirement (OR = 5.61, 95% CI = 2.73-11.52). Inverse predictors of early retirement were cancer remission (OR = 0.23, 95% CI = 0.10-0.53), perceived productivity (OR = 0.38, 95% CI = 0.18-0.83), work satisfaction (OR = 0.36, 95% CI = 0.17-0.77) and mental quality of life (OR = 0.94, 95% CI = 0.91-0.98). This underlines the need for cancer-specific multi-professional rehabilitation and occupational therapy programmes. © 2016 John Wiley & Sons Ltd.

    Little is known about the balance between work demands and treatment plans for >4.3 million working-age cancer survivors in the USA. To describe changes in work status for gynaecological cancer survivors during the first 6 months following diagnosis and their experience with their employers' programmes and policies. One hundred and ten gynaecological cancer survivors who were working at the time of their cancer diagnosis completed a survey. Case record reviews documented their clinical characteristics and treatment details. Ninety-five women (86%) had surgery; 81 (74%) received chemotherapy, radiotherapy or both in addition to surgery. Nine per cent of women said that they changed their treatment plan because of their jobs; in contrast, 62% of women said that they changed their work situation to accommodate their treatment plan. Overall, the most common month for women to stop working was Month 1 (41%), to decrease hours was Month 2 (32%) and to increase hours was Month 6 (8%). Twenty-eight per cent of women were aware of employer policies that assisted the return to work process; 70% of women were familiar with the Family and Medical Leave Act (FMLA) and 56% with the Americans with Disabilities Act (ADA). Only 26% completed a formal request for work accommodations. After 6 months, 56 of 83 women (67%) remained working or had returned to work. Work patterns varied for these gynaecological cancer survivors over the first 6 months following diagnosis. Opportunities exist to improve communication about work and treatment expectations between cancer survivors, occupational health professionals, employers and treating clinicians.

    We investigated changes in the gene expression profile in colon cancer in order to identify gene markers that may be useful in the management of this disease. The Cancer Genome Anatomy Project was used to detect differences in gene expression between normal and cancer tissue. The overexpression of dipeptidase-1 (DPEP1) in cancer tissue was confirmed in a sample of 76 patients by real-time PCR. To identify the function of DPEP1, RNA interference (RNAi) was used to inactivate this gene in the colon cancer cell line. Immunohistochemical analysis was performed to characterize the pattern of DPEP1 expression in colon cancer. DPEP1 expression in cancer was significantly higher than that in normal tissue. However, DPEP1 expression decreased with pathological differentiation, lymph-node and distant metastasis. Patients with tumors with decreased DPEP1 expression showed a poorer prognosis, and this was also true of patients with tumors who are treated with curative intent. RNAi-mediated DPEP1 reduction in the colon cancer cell line did not result in cell proliferation or apoptosis, but was associated with an increased invasive ability. DPEP1 protein was observed on the apical side of the cancer cells, and is expressed in the early stages of carcinogenesis, even in adenomas of both sporadic colorectal cancer and familial adenomatous polyposis patients. DPEP1 expression in normal colonic mucosa is very low, but it is highly expressed in colorectal adenoma and cancer specimens and is negatively correlated with parameters of pathological aggressiveness and poor prognosis. DPEP1 is expressed in the early stages of colon carcinogenesis and affects cancer cell invasiveness.

    The inhibitor of apoptosis (IAP) protein Survivin and its splice variants are differentially expressed in breast cancer tissues. Our previous work showed Survivin is released from tumor cells via small membrane-bound vesicles called exosomes. We, therefore, hypothesize that analysis of serum exosomal Survivin and its splice variants may provide a novel biomarker for early diagnosis of breast cancer. We collected sera from forty breast cancer patients and ten control patients who were disease free for 5 years after treatment. In addition, twenty-three paired breast cancer tumor tissues from those same 40 patients were analyzed for splice variants. Serum levels of Survivin were analyzed using ELISA and exosomes were isolated from this serum using the commercially available ExoQuick kit, with subsequent Western blots and immunohistochemistry performed. Survivin levels were significantly higher in all the breast cancer samples compared to controls (p < 0.05) with exosome amounts significantly higher in cancer patient sera compared to controls (p < 0.01). While Survivin and Survivin-∆Ex3 splice variant expression and localization was identical in serum exosomes, differential expression of Survivin-2B protein existed in the exosomes. Similarly, Survivin and Survivin-∆Ex3 proteins were the predominant forms detected in all of the breast cancer tissues evaluated in this study, whereas a more variable expression of Survivin-2B level was found at different cancer stages. In this study we show for the first time that like Survivin, the Survivin splice variants are also exosomally packaged in the breast cancer patients’ sera, mimicking the survivin splice variant pattern that we also report in breast cancer tissues. Differential expression of exosomal-Survivin, particularly Survivin-2B, may serve as a diagnostic and/or prognostic marker, a “liquid biopsy” if you will, in early breast cancer patients. Furthermore, a more thorough understanding of the role of this

    Gastric cancer is the second cause of cancer-related death in the world, and it remains difficult to cure because it has been in late-stage once that is found. Early gastric cancer detection becomes an effective approach to decrease the gastric cancer mortality. Bioluminescence tomography (BLT) has been applied to detect early liver cancer and prostate cancer metastasis. However, the gastric cancer commonly originates from the gastric mucosa and grows outwards. The bioluminescent light will pass through a non-scattering region constructed by gastric pouch when it transports in tissues. Thus, the current BLT reconstruction algorithms based on the approximation model of radiative transfer equation are not optimal to handle this problem. To address the gastric cancer specific problem, this paper presents a novel reconstruction algorithm that uses a hybrid light transport model to describe the bioluminescent light propagation in tissues. The radiosity theory integrated with the diffusion equation to form the hybrid light transport model is utilized to describe light propagation in the non-scattering region. After the finite element discretization, the hybrid light transport model is converted into a minimization problem which fuses an l1 norm based regularization term to reveal the sparsity of bioluminescent source distribution. The performance of the reconstruction algorithm is first demonstrated with a digital mouse based simulation with the reconstruction error less than 1mm. An in situ gastric cancer-bearing nude mouse based experiment is then conducted. The primary result reveals the ability of the novel BLT reconstruction algorithm in early gastric cancer detection.

    S100A9 was originally discovered as a factor secreted by inflammatory cells. Recently, S100A9 was found to be associated with several human malignancies. The purpose of this study is to investigate S100A9 expression in gastric cancer and explore its role in cancer progression. S100A9 expression in gastric tissue samples from 177 gastric cancer patients was assessed by immunohistochemistry. The expression of its dimerization partner S100A8 and the S100A8/A9 heterodimer were also assessed by the same method. The effect of exogenous S100A9 on motility of gastric cancer cells AGS and BGC-823 was then investigated. S100A9 was specifically expressed by inflammatory cells such as macrophages and neutrophils in human gastric cancer and gastritis tissues. Statistical analysis showed that a high S100A9 cell count (> = 200) per 200x magnification microscopic field in cancer tissues was predictive of early stage gastric cancer. High S100A9-positive cell count was negatively correlated with lymph node metastasis (P = 0.009) and tumor invasion (P = 0.011). S100A9 was identified as an independent prognostic predictor of overall survival of patients with gastric cancer (P = 0.04). Patients with high S100A9 cell count were with favorable prognosis (P = 0.021). Further investigation found that S100A8 distribution in human gastric cancer tissues was similar to S100A9. However, the number of S100A8-positive cells did not positively correlate with patient survival. The inflammatory cells infiltrating cancer were S100A8/A9 negative, while those in gastritis were positive. Furthermore, exogenous S100A9 protein inhibited migration and invasion of gastric cancer cells. Our results suggested S100A9-positive inflammatory cells in gastric cancer tissues are associated with early stage of gastric cancer and good prognosis

    Purpose: To evaluate the relationship of patient, hospital, and cancer characteristics with the adoption of hypofractionation in a national sample of patients diagnosed with early-stage breast cancer. Methods and Materials: We performed a retrospective study of breast cancer patients in the National Cancer Data Base from 2004-2011 who were treated with radiation therapy and met eligibility criteria for hypofractionation. We used logistic regression to identify factors associated with receipt of hypofractionation (vs conventional fractionation). Results: We identified 13,271 women (11.7%) and 99,996 women (88.3%) with early-stage breast cancer who were treated with hypofractionation and conventional fractionation, respectively. The use of hypofractionation increased significantly, with 5.4% of patients receiving it in 2004 compared with 22.8% in 2011 (P<.001 for trend). Patients living ≥50 miles from the cancer reporting facility had increased odds of receiving hypofractionation (odds ratio 1.57 [95% confidence interval 1.44-1.72], P<.001). Adoption of hypofractionation was associated with treatment at an academic center (P<.001) and living in an area with high median income (P<.001). Hypofractionation was less likely to be used in patients with high-risk disease, such as increased tumor size (P<.001) or poorly differentiated histologic grade (P<.001). Conclusions: The use of hypofractionation is rising and is associated with increased travel distance and treatment at an academic center. Further adoption of hypofractionation may be tempered by both clinical and nonclinical concerns.

    The impact of early enteral nutrition (EEN) on clinical outcomes of gastric cancer patients was investigated. Three hundred pa-tients undergoing gastric cancer surgery from July 2010 to May 2014 were randomly divided into experimental and control groups (n = 150/group). Experimental group patients received enteral nutrition in water during the early postoperative period. Control group patients received conventional perioperative treatment. Patients' clinical outcomes, post-operative immune function, and nutritional statuses were compared, which revealed that the postoperative fever duration (80.2 ± 6.0 vs 88.1 ± 8.1 h, P 0.05]. At postoperative days 3 and 7, the CD3(+), CD4(+), natural killer cell, albumin, and prealbumin levels and CD4(+)/CD8(+) ra-tio were significantly higher in the experimental group than the control group (all P nutritional status and immune function and promote early recovery of intestinal function in patients with gastric cancer.

    Full Text Available Objective. To analyze the perception in relation to when and how to perform actions for the early detection of breast and cervical cancer among women and health care providers in communities with a high percentage of indigenous population in Morelos, Mexico. Materials and methods. Ten health providers and 58 women users of health services were interviewed which have a first level of attention in five communities. The analysis was developed under the approach of the Grounded Theory. Results. Providers are poorly informed about current regulations and specific clinical indications for the detection of cervical and breast cancer. Few propitiate health literacy under intercultural sensitization. The users have imprecise or wrong notions of the early detection. Conclusions. The need for training in adherence to norms is evident. It is urgent to assume a culturally relevant approach to enable efficient communication and promote health literacy for early detection of these two cancers.

    We report an experimental study of the possibility of enhancing early bladder cancer diagnosis with fluorescence-image-guided endoscopic optical coherence tomography (OCT). After the intravesical instillation of a 10% solution of 5-aminolevulinic acid, simultaneous fluorescence imaging (excitation of 380-420 nm, emission of 620-700 nm) and OCT are performed on rat bladders to identify the photochemical and morphological changes associated with uroepithelial tumorigenesis. The preliminary results of our ex vivo study reveal that both fluorescence and OCT can identify early uroepithelial cancers, and OCT can detect precancerous lesions (e.g., hyperplasia) that fluorescence may miss. This suggests that a cystoscope combining 5-aminolevulinic acid fluorescence and OCT imaging has the potential to enhance the efficiency and sensitivity of early bladder cancer diagnosis.

    The endoscopic and radiographic findings of 45 gastric adenomas in 39 patients were followed for 6 months to 13 years and compared with type IIa early gastric cancer observed in 9 patients. Difficulties in the diffential diagnosis of these disorders were evaluated. The following features were suggestive of gastric adenomas: clustered lesions; protuberance with gentle slope; smooth surface; and relatively young patients. Discrimination of adenoma from type IIa early gastric cancer is often difficult by visual observation alone; biopsy was essential in most patients. A group III adenoma verified on biopsy should be followed closely because the lesion may harbor a cancer (so-called carcinoma-in-adenoma) or a cancer may later develop. (orig.)

    Breast cancer has become a major cause of death among women. The lifetime risk of a woman developing this disease has been established as one in eight. The most useful way to reduce breast cancer death is to treat the disease as early as possible. The existing methods of early diagnostics of breast cancer are mainly based on screening mammography or Magnetic Resonance Imaging (MRI) periodically conducted at medical facilities. In this paper the authors proposing a new approach for simple breast cancer detection. It is based on skin stimulation by sound waves, illuminating it by laser beam and tracking the reflected secondary speckle patterns. As first approach, plastic balls of different sizes were placed under the skin of chicken breast and detected by the proposed method.

    Full Text Available The endoscopic treatment of cancerous and precancerous lesions in the gastrointestinal (GI tract has experienced major breakthroughs in the past years. Endoscopic mucosal resection (EMR is a simple and efficient method for the treatment of most benign lesions in the GI tract. However, with the introduction of endoscopic submucosal dissection (ESD and endoscopic full-thickness resection (EFTR, the scope of lesions eligible for endoscopic treatment has been widened significantly even in the colon. These methods are now being used routinely not just for the treatment of benign lesions but also in the curative en bloc resection of early colorectal cancers. The quick, efficient, and noninvasive character of these endoscopic procedures make them not just an alternative to surgery but, in many cases, the methods of choice for the treatment of most early colon cancers and some rectal cancers.

    2015-11-01

    Full Text Available Background/Aims: Early parity reduces breast cancer risk, whereas, late parity and nulliparity increase breast cancer risk. Despite substantial efforts to understand the protective effects of early parity, the precise molecular circuitry responsible for these changes is not yet fully defined. Methods: Here, we have conducted the first study assessing protein expression profiles in normal breast tissue of healthy early parous, late parous, and nulliparous women. Breast tissue biopsies were obtained from 132 healthy parous and nulliparous volunteers. These samples were subjected to global protein expression profiling and immunohistochemistry. GeneSpring and MetaCore bioinformatics analysis software were used to identify protein expression profiles associated with early parity (low risk versus late/nulliparity (high risk. Results: Early parity reduces expression of key proteins involved in mitogenic signaling pathways in breast tissue through down regulation of EGFR1/3, ESR1, AKT1, ATF, Fos, and SRC. Early parity is also characterized by greater genomic stability and reduced tissue inflammation based on differential expression of aurora kinases, p53, RAD52, BRCA1, MAPKAPK-2, ATF-1, ICAM1, and NF-kappaB compared to late and nulli parity. Conclusions: Early parity reduces basal cell proliferation in breast tissue, which translates to enhanced genomic stability, reduced cellular stress/inflammation, and thus reduced breast cancer risk.

  1. Coping with Cancer: A Web-based Educational Program for Early and Middle Adolescents

    2010-01-01

    Educating patients is a primary responsibility of all nurses, however due to time constraints and staff shortages, pediatric oncology nurses are often unable to adequately prepare patients for cancer treatment. Instead, patients frequently rely on the Internet as a source of information about cancer, some of which can be outdated and inaccurate. Adolescents regard the Internet to be a valuable source of health information as it is easily accessible, less threatening and confidential. Considering the need for accurate, readily available information for adolescents with cancer, the purpose of this study was to develop and validate an innovative, interactive web-based educational program to prepare early and middle adolescents for cancer treatment. Entitled Coping with Cancer, this program was developed by the investigator after conducting in-depth interviews of adolescent cancer survivors and their parents. Based on the Transactional Model of Coping, the program focuses on enhancing the adolescent’s knowledge of cancer, cancer treatment, and healthy coping strategies. Coping with Cancer can be an effective resource for pediatric oncology nurses in providing ongoing education for adolescents with cancer. PMID:19448133

    This study aims (1) to estimate percentages of partnered women who are sexually active over the first 2 years post-breast cancer diagnosis; (2) to identify factors related to sexual inactivity; and (3) to evaluate separately, among both sexually active and inactive survivors, the relation between sexual problems and treatment-related variables, symptoms, and psychosocial factors. Longitudinal observational study of breast cancer survivors recruited within 8 months of cancer diagnosis and followed for 18 months. The main outcome measures were (1) being sexually active/inactive in the past month and (2) sexual problems assessed with the four-item sexual problem domain of the Quality of Life in Adult Cancer Survivors (QLACS) scale. At baseline, 52.4% of women reported being sexually active in the past month. This percentage increased to 60.7% 18 months later. In multivariable repeated-measures analyses, age, past chemotherapy, depressive symptoms, and lower perceived attractiveness were related to inactivity. Sexually inactive women reported more problems on the QLACS than sexually active women. In stratified multivariable analyses, depressive symptoms were related to greater sexual problems for both sexually active and inactive women, as was vaginal dryness. Among the sexually active women, younger age at diagnosis, less illness intrusiveness, and lower perceived attractiveness were related to more problems. Research has shown that sexual functioning/sexual health are key aspects of quality of life for many cancer survivors, and are often not addressed by health care providers. Future studies should examine how such topics are handled by clinicians in their interactions with survivors.

    In Malawi, routine breast cancer screening is not available and little is known about women's preferences regarding early detection services. Discrete choice experiments are increasingly used to reveal preferences about new health services; however, selecting appropriate attributes that describe a new health service is imperative to ensure validity of the choice experiment. To identify important factors that are relevant to Malawian women's preferences for breast cancer detection services and to select attributes and levels for a discrete choice experiment in a setting where both breast cancer early detection and choice experiments are rare. We reviewed the literature to establish an initial list of potential attributes and levels for a discrete choice experiment and conducted qualitative interviews with health workers and community women to explore relevant local factors affecting decisions to use cancer detection services. We tested the design through cognitive interviews and refined the levels, descriptions, and designs. Themes that emerged from interviews provided critical information about breast cancer detection services, specifically, that breast cancer interventions should be integrated into other health services because asymptomatic screening may not be practical as an individual service. Based on participants' responses, the final attributes of the choice experiment included travel time, health encounter, health worker type and sex, and breast cancer early detection strategy. Cognitive testing confirmed the acceptability of the final attributes, comprehension of choice tasks, and women's abilities to make trade-offs. Applying a discrete choice experiment for breast cancer early detection was feasible with appropriate tailoring for a low-income, low-literacy African setting.

    Background: Carcinogenic exposure in early life may be critical for subsequent breast cancer risk. Dairy consumption was examined during adolescence and early adulthood in relation to incident breast cancer in the Nurses' Health Study II cohort. Methods: For the analyses of early adulthood dairy consumption, we included 90,503 premenopausal women ages 27 to 44 years in 1991 who reported dairy consumption using a validated food-frequency questionnaire. From 1991 to 2013, 3,191 invasive breast cancer cases were identified. In 1998, 44,264 women recalled adolescent dairy consumption. This subgroup of women was followed up from 1998 to 2013; 1,318 invasive breast cancer cases were identified. Multivariate hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using the Cox proportional hazard regression. Results: Adolescent and early adulthood total dairy consumption was not associated with overall breast cancer risk (each serving/day during adolescence, total dairy HR = 1.02, 95% CI, 0.97-1.07; for early adulthood total dairy HR = 1.01, 95% CI, 0.97-1.04), as were intakes of calcium, vitamin D, and lactose. Adolescent consumption of total and high-fat dairy was associated with higher risk of estrogen and progesterone receptor negative (each serving/day: total dairy HR = 1.11, 95% CI, 1.00-1.24; high-fat dairy HR = 1.17, 95% CI, 1.04-1.31). However, higher adolescent high-fat dairy consumption was associated with lower risk of estrogen and progesterone receptor positive tumors (each serving/day HR = 0.91, 95% CI, 0.86-0.97). Conclusions: Our results suggest no overall association between dairy consumption during adolescence or early adulthood and breast cancer risk, but the findings may differ by hormone receptor status of tumors. Impact: Dairy consumption in adolescence or early adulthood may not be a significant predictor of breast cancer incidence.

    Background. Surfaced-enhanced laser desorption-ionization-time of flight mass spectrometry (SELDI-TOF-MS) technology plays an important role in the early diagnosis of ovarian cancer. However, the raw MS data is highly dimensional and redundant. Therefore, it is necessary to study rapid and accurate detection methods from the massive MS data. Methods. The clinical data set used in the experiments for early cancer detection consisted of 216 SELDI-TOF-MS samples. An MS analysis method based on probabilistic principal components analysis (PPCA) and support vector machine (SVM) was proposed and applied to the ovarian cancer early classification in the data set. Additionally, by the same data set, we also established a traditional PCA-SVM model. Finally we compared the two models in detection accuracy, specificity, and sensitivity. Results. Using independent training and testing experiments 10 times to evaluate the ovarian cancer detection models, the average prediction accuracy, sensitivity, and specificity of the PCA-SVM model were 83.34%, 82.70%, and 83.88%, respectively. In contrast, those of the PPCA-SVM model were 90.80%, 92.98%, and 88.97%, respectively. Conclusions. The PPCA-SVM model had better detection performance. And the model combined with the SELDI-TOF-MS technology had a prospect in early clinical detection and diagnosis of ovarian cancer.

    Compelling evidence suggests that early life exposures can affect lifetime cancer risk. In 2014, the Centers for Disease Control and Prevention’s (CDC’s) Cancer Prevention Across the Lifespan Workgroup hosted a series of virtual meetings with select experts to discuss the state of the evidence linking factors during the prenatal period and early childhood to subsequent risk of both pediatric and adult cancers. In this article, we present the results from a qualitative analysis of the meeting transcripts and summarize themes that emerged from our discussions with meeting participants. Themes included the state of the evidence linking early life factors to cancer risk, research gaps and challenges, the level of evidence needed to support taking public health action, and the challenges of communicating complex, and sometimes conflicting, scientific findings to the public. Opportunities for collaboration among public health agencies and other stakeholders were identified during these discussions. Potential next steps for the CDC and its partners included advancing and building upon epidemiology and surveillance work, developing and using evidence from multiple sources to inform decision-making, disseminating and communicating research findings in a clear and effective way, and expanding collaborations with grantees and other partners. As the science on early life factors and cancer risk continues to evolve, there are opportunities for collaboration to translate science into actionable public health practice. PMID:27940972

    Despite the advances in the treatment of HER2-positive breast cancer, resistance to actual chemotherapeutic regimens eventually occurs. Neratinib, an orally available pan-inhibitor of the ERBB family, represents an interesting new option for early-stage HER2-positive breast cancer. Areas covered: In this article, the development of neratinib, with a special focus on its potential value in the treatment of early-stage HER2-positive breast cancer, has been reviewed. For this purpose, a literature search was conducted, including preclinical studies, early-phase trials in advanced cancer with neratinib in monotherapy and in combination, and phase II and large phase III trials in the early setting. Management of neratinib-induced toxicity, future perspectives for the drug, and ongoing trials are also discussed in this review. Expert commentary: Neratinib is emerging as a promising oral drug for the treatment of HER2-positive breast cancer. Although FDA and EMA approval is derived from the extended adjuvant treatment, this setting may not be the ideal scenario to obtain the beneficial effects of neratinib. Confirmatory data in the neoadjuvant setting and subgroup analysis from the ExTENET trial might bring some light into the best setting for neratinib therapy. Data from confirmatory trials in the metastatic setting are also required.

    To investigate the causes of gastric wall shortening in early gastric cancer, upper gastrointestinal study was correlated with pathologic findings. We evaluated 41 cases (M:F = 1.7:1, average age = 49) of early gastric cancer, retrospectively. The gastric wall shortening were classified as Grade I; none, Grade II; intermediate, and Grade III; prominent. Pathologic findings such as size of lesions, depth of tumor invasion, degree of the submucosal fibrosis, degree of thickness of the submucosa and muscularis propria, and morphologic patterns of lesions including conversing mucosal folds were correlated with the degree of gastric wall shortening on upper gastrointestinal series. Submucosal fibrosis was present in 4 cases in Grade I (n = 21), 4 cases in Grade II (n = 6) and 8 cases in Grade III (n = 10). Positive conversing mucosal folds were seen in 5 cases in Grade I (n = 17), 0 case in Grade II (n = 2) and 9 cases in Grade III (n = 9). Gastric wall shortening was significantly associated with submucosal fibrosis and conversing mucosal folds of early gastric cancer. (ρ = 0.0001, and ρ = 0.02, respectively) Upper gastrointestinal finding of gastric wall protrusion in patients with early gastric cancer should not misinterprete as advanced gastric cancer since the finding could be a result of submucosal fibrosis

    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

    To identify and compare levels of distress and sources of problems among patients with breast cancer in early survivorship. Descriptive, cross-sectional. A National Cancer Institute-designated comprehensive cancer center. 100 breast cancer survivors were selected to represent four time points in the cancer trajectory. Distress was self-reported using the Distress Thermometer and its 38-item problem list. Analysis of variance and chi-square analyses were performed as appropriate. Distress scores, problem reports, and time groups. Participants scored in range of the cutoff of more than 4 (range = 4.1-5.1) from treatment through three months post-treatment. At six months post-treatment, distress levels were significantly lower. Significant differences were found between groups on the total problem list score (p = 0.007) and emotional (p = 0.01) and physical subscale scores (p = 0.003). Comparison of groups at different points in the cancer trajectory found similar elevated levels from diagnosis through three months. Distress remained elevated in early survivorship but significantly decreased at six months post-treatment. Interventions to reduce or prevent distress may improve outcomes in early survivorship.

    To elucidate the clinicopathological characteristics of clinically early gastric cancer in the upper-third stomach and to clarify treatment precautions. A total of 683 patients with clinical early gastric cancer were enrolled in this retrospective study, 128 of whom had gastric cancer in the upper-third stomach (U group). All patients underwent a double contrast barium examination, endoscopy, and computed tomography (CT), and were diagnosed preoperatively based on the findings obtained. The clinicopathological features of these patients were compared with those of patients with gastric cancer in the middle- and lower-third stomach (ML group). We also compared clinicopathological factors between accurate-diagnosis and under-diagnosis groups in order to identify factors affecting the accuracy of a preoperative diagnosis of tumor depth. Patients in the U group were older (P = 0.029), had a higher ratio of males to females (P = 0.015), and had more histologically differentiated tumors (P = 0.007) than patients in the ML group. A clinical under-diagnosis occurred in 57 out of 683 patients (8.3%), and was more frequent in the U group than in the ML group (16.4% vs 6.3%, P cancer recurrence was not detected in the U group in the present study. Clinical early gastric cancer in the upper-third stomach has distinguishable characteristics that increase the risk of a clinical under-diagnosis, especially in patients with larger or undifferentiated tumors.

    Early detection of recurrent can improve prognosis and survival of patients with cancer. 18 F- fluorodeoxyglucose( 18 F-FDG) PET can detect metabolic changes before structural changes. The fused imaging provided by PET-CT can precisely localize the foci and demonstrate the complementary roles of functional and anatomic assessments in the diagnosis of cancer recurrence. In addition to the accurate diagnosis and definition of the whole extent of recurrent cancer, 18 F-FDG PET and PET-CT can impact patients management. (authors)

However, the association between APC methylation and the initiation and progression of EC is poorly understood. Purpose and methods: The current study systematically reviewed studies on abnormal methylation of APC in EC and quantitatively synthesized 18 studies by meta-analysis involving 1008 ECs, 570 Barrett’s esophagus (BE, and 782 controls. Results: Our results showed higher methylation of APC in EC (OR = 23.33, P < 0.001 and BE (OR = 9.34, P < 0.001 than in normal controls. Whereas APC methylation in EC was similar to that in BE (P = 0.052, it was not associated with tumor stage (P = 0.204. Additionally, APC methylation was not significantly associated with overall survival (OS and relapse-free survival (RFS in patients with EC. The performance of APC methylation for the detection of EC and BE achieved areas under the receiver operating characteristic curves of 0.94 and 0.88, respectively. Conclusion: Our results imply that APC methylation detection is a potential diagnostic biomarker for EC and BE. Keywords: esophageal cancer, Barrett’s esophagus, methylation, APC

    Urinary cytology is employed in diagnostic guidelines of bladder cancer in anatomo-pathological laboratories mostly for its ability to diagnose non detectable cancers using cystoscopy, but also because it is a non-invasive and non-constraining technique for a regular follow-up of the more exposed populations. The impossibility to detect such cancers is mainly due to their localization either in the bladder or in the upper urinary tract and the prostate. However, urinary cytology lacks sensitivity, especially for the detection of low grade low stage tumors due to inherent limitation of morphological criteria to distinguish low grade tumor cells from normal urothelial cells. For this purpose, we developed, in addition to urinary cytology, an original screening of these cytological slides by using spectrally-resolved and time-resolved fluorescence as a contrast factor, without changing any parameters in the cytological slide preparation. This method takes advantage of a femtosecond Ti:sapphire laser, continuously tunable in the spectral range 700-950 nm allowing the observation of most endogenous cellular chromophores by biphotonic excitation. A commercial confocal microscope was also used in the measurements allowing an excitation of the samples between 458 nm and 633 nm. We observed that the fluorescence emission is differentially distributed in normal and pathological urothelial cells. Spectral- and time-resolved measurements attested this difference over about one hundred cases which have been tested to confirm the high accuracy of this non-invasive technique.

  8. EARLY RECURRENCE OF WELL-DIFFERENTIATED ENDOMETRIAL CANCER (A CASE REPORT

    2017-01-01

    Full Text Available Endometrial cancer is the 6-th most common malignancy in women worldwide, accounting for about 4.8 % of all female cancers. The treatment of recurrent endometrial cancer remains a major challenge. Some endometrial cancer recurrences, for example vaginal stump recurrence, are reported to be effectively treated with surgical resection and radiation therapy. Early recurrence of early-stage well-differentiated endometrial cancer is uncommon. Case report. Herein we report a rare case of recurrent well-differentiated endometrial cancer in a 65-year-old woman. The patient had recurrence 10 months after laparoscopic hysterectomy with bilateral salpingo-oophorectomy. Recurrent endometrial tumor with extension into the rectosigmoid colon, urinary bladder and the right ureter manifested itself clinically with severe pain requiring the use of opioids. The recurrent tumor was removed. Resection of the bladder, left ureter and upper ampular rectum was followed by anastomosis. The patient received multiple cycles of chemotherapy. Conclusion. Compliance with the principles of ablastics during the laparoscopic or laparotomic surgery helps to avoid recurrence in patients with prognostically favorable cancer. In case of recurrence, combined operations are the only possible chance of improving survival of patients with locally advanced or recurrent tumors, which are insensitive to chemoradiotherapy.

    Standard of care treatment for most stage I rectal cancers is total mesorectal excision (TME). Given the morbidity associated with TME, local excision (LE) for early-stage rectal cancer has been explored. This study examines practice patterns and overall survival (OS) for early-stage rectal cancer. All patients in the National Cancer Data Base diagnosed with rectal cancer from 1998 to 2010 were initially included. Use of LE versus proctectomy and use of adjuvant radiation therapy were compared over time. Adjusted Cox proportional hazards models were used to compare OS based on treatment. LE was used to treat 46.5% of patients with T1 and 16.8% with T2 tumors. Use of LE increased steadily over time (P OS than those treated with proctectomy alone or multimodality therapy. Guideline-concordant adoption of LE for treatment of low-risk stage I rectal cancer is increasing. However, use of LE is also increasing for higher-risk rectal cancers that do not meet guideline criteria for LE. Treatment with LE alone is associated with poorer long-term OS. Additional studies are warranted to understand the factors driving increased use of LE.

    Full Text Available Abstract Background The Comprehensive Geriatric Assessment (CGA is an analytical tool increasingly implemented in clinical practice. Breast cancer is primarily a disease of older people; however, most evidence-based research is aimed at younger patients. Methods A systematic review of literature was carried out to assess the use of CGA in older breast cancer patients for clinical decision making. The PubMed, Embase and Cochrane databases were searched. Results A total of nine useful full text article results were found. Only five of these were exclusively concerned with early breast cancer; thus, studies involving a variety of cancer types, stages and treatments were accepted, as long as they included early breast cancer.The results comprised a series of low sources of evidence. However, all results shared a common theme: the CGA has a use in determining patient suitability for different types of cancer treatment and subsequently maximizing the patient’s quality of life. Conclusions There is not yet sufficient high level evidence to instate CGA guidelines as a mandatory practice in the management of breast cancer, due to the heterogeneity of available studies. More studies need to be conducted to cement current work on the benefits of the CGA. An area of particular interest is with regard to treatment options, especially surgery and chemotherapy, and identifying patients who may be suitable for these treatments.

    Most women with breast cancer who undergo breast-conserving surgery receive whole-breast irradiation. We examined whether the addition of regional nodal irradiation to whole-breast irradiation improved outcomes. We randomly assigned women with node-positive or high-risk node-negative breast cancer who were treated with breast-conserving surgery and adjuvant systemic therapy to undergo either whole-breast irradiation plus regional nodal irradiation (including internal mammary, supraclavicular, and axillary lymph nodes) (nodal-irradiation group) or whole-breast irradiation alone (control group). The primary outcome was overall survival. Secondary outcomes were disease-free survival, isolated locoregional disease-free survival, and distant disease-free survival. Between March 2000 and February 2007, a total of 1832 women were assigned to the nodal-irradiation group or the control group (916 women in each group). The median follow-up was 9.5 years. At the 10-year follow-up, there was no significant between-group difference in survival, with a rate of 82.8% in the nodal-irradiation group and 81.8% in the control group (hazard ratio, 0.91; 95% confidence interval [CI], 0.72 to 1.13; P=0.38). The rates of disease-free survival were 82.0% in the nodal-irradiation group and 77.0% in the control group (hazard ratio, 0.76; 95% CI, 0.61 to 0.94; P=0.01). Patients in the nodal-irradiation group had higher rates of grade 2 or greater acute pneumonitis (1.2% vs. 0.2%, P=0.01) and lymphedema (8.4% vs. 4.5%, P=0.001). Among women with node-positive or high-risk node-negative breast cancer, the addition of regional nodal irradiation to whole-breast irradiation did not improve overall survival but reduced the rate of breast-cancer recurrence.

    The heterogeneity of breast cancer makes identifying effective therapies challenging. The I-SPY 2 trial, a multicenter, adaptive phase 2 trial of neoadjuvant therapy for high-risk clinical stage II or III breast cancer, evaluated multiple new agents added to standard chemotherapy to assess the effects on rates of pathological complete response (i.e., absence of residual cancer in the breast or lymph nodes at the time of surgery). We used adaptive randomization to compare standard neoadjuvant chemotherapy plus the tyrosine kinase inhibitor neratinib with control. Eligible women were categorized according to eight biomarker subtypes on the basis of human epidermal growth factor receptor 2 (HER2) status, hormone-receptor status, and risk according to a 70-gene profile. Neratinib was evaluated against control with regard to 10 biomarker signatures (prospectively defined combinations of subtypes). The primary end point was pathological complete response. Volume changes on serial magnetic resonance imaging were used to assess the likelihood of such a response in each patient. Adaptive assignment to experimental groups within each disease subtype was based on Bayesian probabilities of the superiority of the treatment over control. Enrollment in the experimental group was stopped when the 85% Bayesian predictive probability of success in a confirmatory phase 3 trial of neoadjuvant therapy reached a prespecified threshold for any biomarker signature ("graduation"). Enrollment was stopped for futility if the probability fell to below 10% for every biomarker signature. Neratinib reached the prespecified efficacy threshold with regard to the HER2-positive, hormone-receptor-negative signature. Among patients with HER2-positive, hormone-receptor-negative cancer, the mean estimated rate of pathological complete response was 56% (95% Bayesian probability interval [PI], 37 to 73%) among 115 patients in the neratinib group, as compared with 33% among 78 controls (95% PI, 11 to 54

    To clarify the biological impact and molecular pathogenesis of cellular phenotype in differentiated-type gastric cancers (DGCs), we investigated cell kinetics and genetic instabilities in early stage of DGCs. A total of 43 early gastric cancers (EGCs) were studied. EGCs were divided into 3 phenotypic categories: gastric (G type, n = 11), ordinary (O type, n = 20), and complete intestinal (CI type, n = 12) based on the combination of HGM, ConA, MUC2, and CD10. Proliferative index (PI), apoptotic index (AI), and p53 overexpression were investigated by immunohistochemical staining with anti-Ki-67, the terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labeling method, and p53 antibody, respectively. Using a high-resolution fluorescent microsatellite analysis system, microsatellite instability (MSI) and loss of heterozygosity (LOH) were examined. Frameshift mutation analysis of transforming growth factor-beta type II receptor (TGF-betaRII) and bcl-2-associated X (BAX) in cancers with MSI was also performed. The mean AI/PI ratio values were 0.04 for G-type, 0.10 for O-type, and 0.13 for CI-type cancers--significantly lower in G type than in O and CI types (P = 0.02 and P = 0.001, respectively). No difference in the incidence of MSI and LOH was seen among the 3 cellular phenotypes. However, the major pattern of MSI, which showed drastic and widely dispersed changes and is related to an increased risk for cancer, was significantly higher in G and O types than in CI type (P cancers. These results indicate that G-type cancers are likely to show more aggressive behaviors than CI-type cancers, and that O-type cancers show the intermediate characteristics of both types. However, the molecular pathogenesis of each phenotypic cancer is not associated with microsatellite alterations. Copyright 2003, Elsevier Science (USA). All rights reserved.

  14. Multianalyte Tests for the Early Detection of Cancer: Speedbumps and Barriers

    Full Text Available It has become very clear that a single molecular event is inadequate to accurately predict the biology (or pathophysiology of cancer. Furthermore, using any single molecular event as a biomarker for the early detection of malignancy may not comprehensively identify the majority of individuals with that disease. Therefore, the fact that technologies have arisen that can simultaneously detect several, possibly hundreds, of biomarkers has propelled the field towards the development of multianalyte-based in vitro diagnostic early detection tests for cancer using body fl uids such as serum, plasma, sputum, saliva, or urine. These multianalyte tests may be based on the detection of serum autoantibodies to tumor antigens, the presence of cancer-related proteins in serum, or the presence of tumor-specific genomic changes that appear in plasma as free DNA. The implementation of non-invasive diagnostic approaches to detect early stage cancer may provide the physician with evidence of cancer, but the question arises as to how the information will affect the pathway of clinical intervention. The confirmation of a positive result from an in vitro diagnostic cancer test may involve relatively invasive procedures to establish a true cancer diagnosis. If in vitro diagnostic tests are proven to be both specific, i.e. rarely produce false positive results due to unrelated conditions, and sufficiently sensitive, i.e. rarely produce false negative results, then such screening tests offer the potential for early detection and personalized therapeutics using multiple disease-related targets with convenient and non-invasive means. Here we discuss the technical and regulatory barriers inherent in development of clinical multianalyte biomarker assays.

    To investigate the value of circulating miR-152 in the early prediction of postoperative biochemical recurrence of prostate cancer. Sixty-six cases of prostate cancer were included in this study, 35 with and 31 without biochemical recurrence within two years postoperatively, and another 31 healthy individuals were enrolled as normal controls. The relative expression levels of circulating miR-152 in the serum of the subjects were detected by qRT-PCR, its value in the early diagnosis of postoperative biochemical recurrence of prostate cancer was assessed by ROC curve analysis, and the correlation of its expression level with the clinicopathological parameters of the patients were analyzed. The expression of circulating miR-152 was significantly lower in the serum of the prostate cancer patients than in the normal controls (t = -5.212, P = 0.001), and so was it in the patients with than in those without postoperative biochemical recurrence (t = -5.727, P = 0.001). The ROC curve for the value of miR-152 in the early prediction of postoperative biochemical recurrence of prostate cancer showed the area under the curve (AUC) to be 0.906 (95% CI: 0.809-0.964), with a sensitivity of 91.4% and a specificity of 80.6%. The expression level of miR-152 was correlated with the Gleason score, clinical stage of prostate cancer, biochemical recurrence, and bone metastasis (P 0.05). The expression level of circulating miR-152 is significantly reduced in prostate cancer patients with biochemical recurrence after prostatectomy and could be a biomarker in the early prediction of postoperative biochemical recurrence of the malignancy.

    Objective To examine the prevalence of, and risk factors for, depression and anxiety in women with early breast cancer in the five years after diagnosis. Design Observational cohort study. Setting NHS breast clinic, London. Participants 222 women with early breast cancer: 170 (77%) provided complete interview data up to either five years after diagnosis or recurrence. Main outcome measures Prevalence of clinically important depression and anxiety (structured psychiatric interview with standardised diagnostic criteria) and clinical and patient risk factors, including stressful life experiences (Bedford College life events and difficulties schedule). Results Nearly 50% of the women with early breast cancer had depression, anxiety, or both in the year after diagnosis, 25% in the second, third, and fourth years, and 15% in the fifth year. Point prevalence was 33% at diagnosis, falling to 15% after one year. 45% of those with recurrence experienced depression, anxiety, or both within three months of the diagnosis. Previous psychological treatment predicted depression, anxiety, or both in the period around diagnosis (one month before diagnosis to four months after diagnosis). Longer term depression and anxiety, were associated with previous psychological treatment, lack of an intimate confiding relationship, younger age, and severely stressful non-cancer life experiences. Clinical factors were not associated with depression and anxiety, at any time. Lack of intimate confiding support also predicted more protracted episodes of depression and anxiety. Conclusion Increased levels of depression, anxiety, or both in the first year after a diagnosis of early breast cancer highlight the need for dedicated service provision during this time. Psychological interventions for women with breast cancer who remain disease free should take account of the broader social context in which the cancer occurs, with a focus on improving social support.

    The incidence of new primary cancers was evaluated in 3538 postmenopausal patients who had received surgical treatment for primary breast cancer. Of these patients, 1828 with a low risk of recurrence received no further treatment. High-risk patients were randomly assigned to one of two groups. The first group (n = 846) received postoperative radiotherapy, while the second group (n = 864) received radiotherapy plus tamoxifen at a dose of 30 mg given daily for 48 weeks. The median observation time was 7.9 years. In comparison with the number of new cancers in the general population, the number of new cancers in the three groups was elevated mostly due to a high number of cancers of the contralateral breast and of colorectal cancers in the high-risk groups. The cumulative risk of nonlymphatic leukemia was increased among patients who received postoperative radiotherapy (P = .04). Cancer incidence in the high-risk tamoxifen-treated group relative to that in the high-risk group not treated with tamoxifen was not significant (1.3). No protective effect of tamoxifen on the opposite breast was seen (rate ratio for breast cancer = 1.1), but a tendency to an elevated risk of endometrial cancer was observed (rate ratio = 3.3; 95% confidence interval = 0.6-32.4). Continued and careful follow-up of women treated with tamoxifen is necessary to clarify the potential cancer-suppressive or cancer-promoting effects of this drug

Discrete choice experiments are increasingly used to reveal preferences about new health services; however, selecting appropriate attributes that describe a new health service is imperative to ensure validity of the choice experiment.Objective: To identify important factors that are relevant to Malawian women’s preferences for breast cancer detection services and to select attributes and levels for a discrete choice experiment in a setting where both breast cancer early detection and choice experiments are rare.Methods: We reviewed the literature to establish an initial list of potential attributes and levels for a discrete choice experiment and conducted qualitative interviews with health workers and community women to explore relevant local factors affecting decisions to use cancer detection services. We tested the design through cognitive interviews and refined the levels, descriptions, and designs.Results: Themes that emerged from interviews provided critical information about breast cancer detection services, specifically, that breast cancer interventions should be integrated into other health services because asymptomatic screening may not be practical as an individual service. Based on participants’ responses, the final attributes of the choice experiment included travel time, health encounter, health worker type and sex, and breast cancer early detection strategy. Cognitive testing confirmed the acceptability of the final attributes

    The treatment of primary breast cancer usually consists of surgery often followed by adjuvant therapy (radiotherapy, chemotherapy, hormonal treatment, etc.) to reduce the risk of recurrence. The cancer diagnosis and the treatments may have significant impact on the patients' quality of life. This thesis deals with scientific aspects and clinical results of a study aimed at assessing the impact of breast cancer (and its treatment) on the patients' quality of life. Studies such as this assessing the problems and symptoms experienced by the patients are often referred to as health-related quality of life (HRQL) research. HRQL research deals with subjective experiences and raises challenging, scientific questions. Therefore, much attention was directed towards methodological issues in this clinically motivated project. The study was a prospective, longitudinal, questionnaire-based investigation of women with newly diagnosed breast cancer registered in the Danish Breast Cancer Co-operative Group's DBCG 89 Program. The patients were sub-divided into low-risk and high-risk patients. High-risk patients were offered randomisation in one of three randomised adjuvant therapy trials involving chemotherapy, ovarian ablation, and endocrine therapy. After a literature study and interviews with breast cancer patients, a questionnaire was composed that included two widely used standard questionnaires (EORTC QLQ-C30 and Hospital Anxiety and Depression (HAD) Scale) and a DBCG 89 Questionnaire developed for this study. A total of 1,898 eligible patients were invited by post to participate in the study involving six assessments over a 2-year period, and 1,713 patients (90%) completed the first questionnaire. Furthermore, a questionnaire was sent to 872 women selected at random from the general population; 608 (70%) responded. The multi-item scales of the two standard questionnaires were analysed for so-called differential item functioning (DIF) in order to investigate whether the

    Purpose: 1) To define the incidence of isolated lung events in a cohort of women treated with conservative surgery (CS) and radiation therapy (RT) for early stage breast cancer. 2) Among such patients, to define the relative distribution of primary lung cancer, metastatic breast cancer, and indeterminate lesions; and to identify any predictors for a diagnosis of lung vs metastatic breast cancer. 3) To examine the cohort with respect to whether a higher than expected incidence of lung cancer is seen following breast irradiation. Materials and Methods: Between 1968 and 1986, 1865 patients with clinical stage I-II breast cancer were treated with CS and RT; the median follow-up for surviving patients is 129 months. The study population was limited to patients who developed a subsequent isolated lung event as the first site of distant disease. Isolated lung event was defined as disease limited to the thoracic cavity, without evidence of either uncontrolled local breast disease or metastatic disease elsewhere. Diagnosis of the lung event as a primary lung cancer, a metastatic breast lesion, or an indeterminate lesion was documented from the viewpoint of 1) the pathologic analysis and 2) the clinical impression at the time of the lung event. Results: Sixty six of the 1865 patients (3.5%) developed an isolated lung event. The relative distribution of the pathologic and clinical diagnoses is shown below: The 66 lung events were characterized either as a solitary pulmonary nodule (27), multiple nodules (23), pleural effusion alone (10), unknown (2), or miscellaneous other findings (4). Among the 47 patients for whom pathology was available, the diagnosis remained indeterminate for 24 (51%). For patients with a definitive pathologic diagnosis, 69% ((9(13))) of smokers had a new lung cancer compared to 20% ((2(10))) of non-smokers (p=0.036), and 67% ((10(15))) of patients with a solitary pulmonary nodule had lung cancer compared to 14% ((1(7))) for other lung presentations (p

    The diagnosis and subsequent treatment for early stage breast cancer is stressful for partners. Little is known about the role of cognitive and social processes predicting the longitudinal course of partners' psychosocial adaptation. This study evaluated the role of cognitive and social processing in partner psychological adaptation to early stage breast cancer, evaluating both main and moderator effect models. Moderating effects for meaning making, acceptance, and positive reappraisal on the predictive association of searching for meaning, emotional processing, and emotional expression on partner psychological distress were examined. Partners of women diagnosed with early stage breast cancer were evaluated shortly after the ill partner's diagnosis (N=253), 9 (N=167), and 18 months (N=149) later. Partners completed measures of emotional expression, emotional processing, acceptance, meaning making, and general and cancer-specific distress at all time points. Lower satisfaction with partner support predicted greater global distress, and greater use of positive reappraisal was associated with greater distress. The predicted moderator effects for found meaning on the associations between the search for meaning and cancer-specific distress were found and similar moderating effects for positive reappraisal on the associations between emotional expression and global distress and for acceptance on the association between emotional processing and cancer-specific distress were found. Results indicate several cognitive-social processes directly predict partner distress. However, moderator effect models in which the effects of partners' processing depends upon whether these efforts result in changes in perceptions of the cancer experience may add to the understanding of partners' adaptation to cancer.

    Early diagnosis is very important to improve the survival rate of patients with gastric cancer and to understand the biology of cancer. In order to meet the clinical demands for early diagnosis of gastric cancer, we developed a disposable easy-to-use electrochemical microfluidic chip combined with multiple antibodies against six kinds of biomarkers (carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9), Helicobacter pylori CagA protein (H.P.), P53oncoprotein (P53), pepsinogen I (PG I), and PG-II). The six kinds of biomarkers related to gastric cancer can be detected sensitively and synchronously in a short time. The specially designed three electrodes system enables cross-contamination to be avoided effectively. The linear ranges of detection of the electrochemical microfluidic chip were as follows: 0.37-90 ng mL-1 for CEA, 10.75-172 U mL-1 for CA19-9, 10-160 U L-1 for H.P., 35-560 ng mL-1 for P53, 37.5-600 ng mL-1 for PG I, and 2.5-80 ng mL-1for PG II. This method owns better sensitivity compared with enzyme-linked immunosorbent assay (ELISA) results of 394 specimens of gastric cancer sera. Furthermore, we established a multi-index prediction model based on the six kinds of biomarkers for predicting risk of gastric cancer. In conclusion, the electrochemical microfluidic chip for detecting multiple biomarkers has great potential in applications such as early screening of gastric cancer patients, and therapeutic evaluation, and real-time dynamic monitoring the progress of gastric cancer in near future.

  3. Apolipoprotein E Allelic Frequency Altered in Women with Early-onset Breast Cancer

    Full Text Available Among women, the most prevalent type of cancer is breast cancer, affecting 1 out of every 8 women in the United States; in Puerto Rico, 70 out of every 100,000 will develop some type of breast cancer. Therefore, a better understanding of the potential risk factors for breast cancer could lead to the development of early detection tools. A gene that has been proposed as a risk factor in several populations around the world is Apolipoprotein E (apoE. ApoE functions as a mechanism of transport for lipoproteins and cholesterol throughout the body, with 3 main isoforms present in humans (apoE2, apoE3, and apoE4. Whether or not apoE4 is a risk factor for breast cancer remains controversial. Previous studies have either included test subjects of all ages (20–80 or have focused on late-onset (after age 50 breast cancer; none has concentrated specifically on early-onset (aged 50 and younger breast cancer. The objectives of this study was to examine (in a Puerto Rican population the differences in the relative frequency of occurrence of apoE4 in non-breast cancer versus breast cancer patients and to examine, as well, the potential differences of same in early- versus late-onset patients. We found an increased frequency of apoE4 (odds ratio 2.15 only in early-onset breast cancer survivors, which is similar to the findings of those studies that combined or adjusted for age as well as for an association between apoE4 and decreased tumor size. ApoE is also a potential risk factor for long-term cognitive effects after chemotherapy and affects response to hormone replacement. Our data supports the theory that knowing the apoE genotype of women who are at risk of developing breast cancer may be beneficial, as such knowledge would aid in the prediction of tumor size and the development of treatment regimens.

    Our objective is to evaluate the mental status of primary early breast cancer survivors according to DSM-IV criteria, distinguishing new psychiatric diagnosis, which started after the cancer diagnosis from relapse. A comparative study of 144 breast cancer survivors and 125 women without previous history of cancer was carried out. Neuropsychiatric symptomatology was assessed retrospectively using standardized psychiatric examinations (Mini International Neuropsychiatric Interview, Watson's Post-Traumatic Stress Disorder Inventory) over three successive periods, 'before cancer' (from childhood to 3 years before the interview), 'around the cancer event' (the last 3 years including the time of diagnosis and treatment), and 'currently' (the last 2 weeks). Increased rates of anxiety and mood disorders were observed following a diagnosis of breast cancer compared with controls (generalized anxiety disorder (GAD) and major depressive disorder (MDD); 10.4 vs 1.6% and 19.4 vs 8.8%, respectively). The cancer disease promoted the development of dysthymia (n=4 new cases/6 two-year prevalent cases) and PTSD (7/7) and the re-emergence of MDD (n=21 relapses/28 three-year prevalent cases) and GAD (10/15). No improvement in serious mood disorders such as MDD (16.0 vs 7.2%) and dysthymia (4.2 vs 0%) was reported at the time of interview, more than 1.75 years (median time) after the cancer surgery, the prevalence being 2-4 times greater in breast cancer survivors than in controls. Despite significant advances in treatment, a diagnosis of breast cancer is highly associated with various forms of psychopathology, regardless of psychiatric history, with symptoms persisting after treatment. These results may assist clinicians in planning mental healthcare for women with breast cancer.

    The hypermethylation of APC gene is observed in various cancers, including esophageal cancer (EC). However, the association between APC methylation and the initiation and progression of EC is poorly understood. The current study systematically reviewed studies on abnormal methylation of APC in EC and quantitatively synthesized 18 studies by meta-analysis involving 1008 ECs, 570 Barrett's esophagus (BE), and 782 controls. Our results showed higher methylation of APC in EC (OR = 23.33, P APC methylation in EC was similar to that in BE ( P = 0.052), it was not associated with tumor stage ( P = 0.204). Additionally, APC methylation was not significantly associated with overall survival (OS) and relapse-free survival (RFS) in patients with EC. The performance of APC methylation for the detection of EC and BE achieved areas under the receiver operating characteristic curves of 0.94 and 0.88, respectively. Our results imply that APC methylation detection is a potential diagnostic biomarker for EC and BE.

    Full Text Available In India, the oral cancers are usually presented in advanced stage of malignancy. It is critical to ascertain the diagnosis in order to initiate most advantageous treatment of the suspicious lesions. The main hurdle in appropriate treatment and control of oral cancer is identification and risk assessment of early disease in the community in a cost-effective fashion. The objective of this research is to design a data mining model using probabilistic neural network and general regression neural network (PNN/GRNN for early detection and prevention of oral malignancy. The model is built using the oral cancer database which has 35 attributes and 1025 records. All the attributes pertaining to clinical symptoms and history are considered to classify malignant and non-malignant cases. Subsequently, the model attempts to predict particular type of cancer, its stage and extent with the help of attributes pertaining to symptoms, gross examination and investigations. Also, the model envisages anticipating the survivability of a patient on the basis of treatment and follow-up details. Finally, the performance of the PNN/GRNN model is compared with that of other classification models. The classification accuracy of PNN/GRNN model is 80% and hence is better for early detection and prevention of the oral cancer.

    In India, the oral cancers are usually presented in advanced stage of malignancy. It is critical to ascertain the diagnosis in order to initiate most advantageous treatment of the suspicious lesions. The main hurdle in appropriate treatment and control of oral cancer is identification and risk assessment of early disease in the community in a cost-effective fashion. The objective of this research is to design a data mining model using probabilistic neural network and general regression neural network (PNN/GRNN) for early detection and prevention of oral malignancy. The model is built using the oral cancer database which has 35 attributes and 1025 records. All the attributes pertaining to clinical symptoms and history are considered to classify malignant and non-malignant cases. Subsequently, the model attempts to predict particular type of cancer, its stage and extent with the help of attributes pertaining to symptoms, gross examination and investigations. Also, the model envisages anticipating the survivability of a patient on the basis of treatment and follow-up details. Finally, the performance of the PNN/GRNN model is compared with that of other classification models. The classification accuracy of PNN/GRNN model is 80% and hence is better for early detection and prevention of the oral cancer.

    To use health economics methodology to assess the screening program on gastric cancer in Zhuanghe, China, so as to provide the basis for health decision on expanding the program of early detection and treatment. The expense of an early detection and treatment program for gastric cancer in patients found by screening, and also costs of traditional treatment in a hospital of Zhuanghe were assessed. Three major techniques of medical economics, namely cost-effective analysis (CEA), cost-benefit analysis (CBA) and cost-utility analysis (CUA), were used to assess the screening program. RESULTS from CEA showed that investing every 25, 235 Yuan on screening program in Zhuanghe area, one gastric cancer patient could be saved. Data from CUA showed that it was cost 1, 370 Yuan per QALY saved. RESULTS from CBA showed that: the total cost was 1,945,206 Yuan with a benefit as 8,669,709 Yuan and an CBR of 4.46. The early detection and treatment program of gastric cancer appears economic and society-beneficial. We suggest that it should be carry out in more high risk areas for gastric cancer.

    Breast cancer is a major health problem that affects one in eight women worldwide. As such, detecting breast cancer at an early stage anticipates better disease outcome and prolonged patient survival. Extensive research has shown that microRNA (miRNA) are dysregulated at all stages of breast cancer. miRNA are a class of small noncoding RNA molecules that can modulate gene expression and are easily accessible and quantifiable. This review highlights miRNA as diagnostic, prognostic and therapy predictive biomarkers for early breast cancer with an emphasis on the latter. It also examines the challenges that lie ahead in their use as biomarkers. Noteworthy, this review addresses miRNAs reported in patients with early breast cancer prior to chemotherapy, radiotherapy, surgical procedures or distant metastasis (unless indicated otherwise). In this context, miRNA that are mentioned in this review were significantly modulated using more than one statistical test and/or validated by at least two studies. A standardized protocol for miRNA assessment is proposed starting from sample collection to data analysis that ensures comparative analysis of data and reproducibility of results.

    The purpose of this study was to assess the cardiac side effects, primarily the occurrence of ischemic heart disease, in symptom-free patients with early breast cancer treated with radiotherapy. Thirty-seven survivors of a former randomized study of early breast cancer were examined. Twenty patients irradiated pre- or postoperatively for left sided disease (study group patients) were compared with 17 controls who were either treated for right sided disease, or were nonirradiated patients. Radiotherapy was randomized in the original study; either tangential field 60 Co, or electron-therapy was delivered. Echocardiography and bicycle ergometry stress test with 99m Tc SestaMIBI myocardial perfusion scintigraphy were carried out and the patients' major risk factors for ischemic heart disease were also listed. Our results showed a significant difference between the scintigraphic findings of the two groups. Five of the 20 study group patients (25%), while none of the 17 controls exhibited some kind of significant defects on scintigraphy, indicating ischemic heart disease (p < 0.05). No deterioration in left ventricular systolic and/or diastolic function could be detected by echocardiography. Radiotherapy for left sided breast cancer with the mentioned treatment technique may present as an independent risk factor in the long-term development of ischemic heart disease, while left ventricular dysfunction could not be related to the previous irradiation. The authors emphasize the need to optimize adjuvant radiotherapy for early breast cancer by considering the dose both to the heart as well as the cancer. 39 refs., 4 tabs

    Mammography is at present one of the available method for early detection of masses or abnormalities which is related to breast cancer.The calcifications. The challenge lies in early and accurate detection to overcome the development of breast cancer that affects more and more women throughout the world. Breast cancer is diagnosed at advanced stages with the help of the digital mammogram images. Masses appear in a mammogram as fine, granular clusters, which are often difficult to identify in a raw mammogram. The incidence of breast cancer in women has increased significantly in recent years. This paper proposes a computer aided diagnostic system for the extraction of features like mass lesions in mammograms for early detection of breast cancer. The proposed technique is based on a four-step procedure: (a) the preprocessing of the image is done, (b) regions of interest (ROI) specification, (c) supervised segmentation method includes two to stages performed using the minimum distance (M D) criterion, and (d) feature extraction based on Gray level Co-occurrence matrices GLC M for the identification of mass lesions. The method suggested for the detection of mass lesions from mammogram image segmentation and analysis was tested over several images taken from A L-llwiya Hospital in Baghdad, Iraq.The proposed technique shows better results.

    Early cancer detection and treatment is an emerging and fascinating field of plasmonic nanobiosensor research. It paves to enrich a life without affecting living cells leading to a possible survival of the patient. This review describes a past and future prospect of an integrated research field on nanostructured metamaterials, microwave transmission, surface plasmonic resonance, nanoantennas, and their manifested versatile properties with nano-biosensors towards early cancer detection to preserve human health. Interestingly, (i) microwave transmission shows more advantages than other electromagnetic radiation in reacting with biological tissues, (ii) nanostructured metamaterial (Au) with special properties like size and shape can stimulate plasmonic effects, (iii) plasmonic based nanobiosensors are to explore the efficacy for early cancer tumour detection or single molecular detection and (iv) nanoantenna wireless communication by using microwave inverse scattering nanomesh (MISN) technique instead of conventional techniques can be adopted to characterize the microwave scattered signals from the biomarkers. It reveals that the nanostructured material with plasmonic nanobiosensor paves a fascinating platform towards early detection of cancer tumour and is anticipated to be exploited as a magnificent field in the future.

    Early detection of metastasis can be aided by circulating tumor cells (CTC), which also show potential to predict early relapse. Because of the limited CTC numbers in peripheral blood in early stages, we investigated CTCs in pulmonary vein blood accessed during surgical resection of tumors. Pulmonary vein (PV) and peripheral vein (Pe) blood specimens from patients with lung cancer were drawn during the perioperative period and assessed for CTC burden using a microfluidic device. From 108 blood samples analyzed from 36 patients, PV had significantly higher number of CTCs compared with preoperative Pe ( P ontology analysis revealed enrichment of cell migration and immune-related pathways in CTC clusters, suggesting survival advantage of clusters in circulation. Clusters display characteristics of therapeutic resistance, indicating the aggressive nature of these cells. Thus, CTCs isolated from early stages of lung cancer are predictive of poor prognosis and can be interrogated to determine biomarkers predictive of recurrence.

    Wilkes, L; Withnall, J; Harris, R; White, K; Beale, B; Hobson, J; Durham, M; Kristjanson, L

    2001-06-01

    Sixty articles in five Australian women's magazines were analyzed for journalistic qualities, metaphors, narrative features and accuracy of clinical facts related to risk, early detection and treatment of breast cancer. The stories were features, news features or soft news stories. The stories reflected the 'good news' editorial style of women's magazines. A dominant theme in the stories was that early detection of breast cancer is crucial and equals survival. While there were few inaccuracies in the stories, there was little detail of treatment modalities, an emphasis on lifestyle as a risk factor and a prevailing message that a genetic history of breast cancer means you will get it. A major implication of the findings is that nurses, who provide information to women, must be aware of the goals of journalists and the educational power of narrative logic of stories in women's magazines.

  18. Multiparametric MRI of the prostate. Method for early detection of prostate cancer?

    International Nuclear Information System (INIS)

    Schlemmer, Heinz-Peter

    2010-01-01

    Current approaches for the early detection of prostate cancer are controversially discussed because the disease is characterized by a high incidence rate with a relatively low morbidity rate, availability of only limited prognostic markers, and continued therapy-related morbidity. Conventional morphological MRI does not play a role in early detection since small tumor foci cannot be delineated. However, if there is clinical suspicion for prostate cancer, multiparametric MRI is currently the most accurate method for detecting and characterizing suspicious lesions in the prostate. The potential to identify the so-called 'index lesion', i.e., the tumor area that is most aggressive and determines treatment, is particularly important. This information can increase the accuracy of prostate biopsy and serve as a biomarker for follow-up during active surveillance. The method may considerably contribute to the urgently required separation of clinically significant from clinically insignificant prostate cancers. (orig.)

    By the help of successes achieved in Japan in the control of gastrocarcinoma, tasks, possibilities and limits in X-ray diagnostics are outlined, strategically holding hitherto a key position in the recording of patients with early carcinoma of the stomach. X-ray symptoms, the classification of tumor-finding, X-ray examination-methods, their relation to gastroscopy as well as the radiation dose and problems of economy of X-ray examinations are discussed. On account of the achieved recognition prophylactic examinations are to be concentrated to risk groups (anaemia perniciosa, polyposis ventriculi, late state after gastrectomy, ulcus ventriculi).

    The number of lymph nodes found to be involved in an axillary dissection is among the most powerful prognostic factors in breast cancer, but it is confounded by the number of lymph nodes that have been examined. We investigate an idea that has surfaced recently in the literature (since 1999), namely that the proportion of node-positive lymph nodes (or a function thereof) is a much better predictor of survival than the number of excised and node-positive lymph nodes, alone or together. The data were abstracted from 83,686 cases registered in the Surveillance, Epidemiology, and End Results (SEER) program of women diagnosed with nonmetastatic T1–T2 primary breast carcinoma between 1988 and 1997, in whom axillary node dissection was performed. The end-point was death from breast cancer. Cox models based on different expressions of nodal involvement were compared using the Nagelkerke R 2 index (R 2 N ). Ratios were modeled as percentage and as log odds of involved nodes. Log odds were estimated in a way that avoids singularities (zero values) by using the empirical logistic transform. In node-negative cases both the number of nodes excised and the log odds were significant, with hazard ratios of 0.991 (95% confidence interval 0.986–0.997) and 1.150 (1.058–1.249), respectively, but without improving R 2 N . In node-positive cases the hazard ratios were 1.003–1.088 for the number of involved nodes, 0.966–1.005 for the number of excised nodes, 1.015–1.017 for the percentage, and 1.344–1.381 for the log odds. R 2 N improved from 0.067 (no nodal covariate) to 0.102 (models based on counts only) and to 0.108 (models based on ratios). Ratios are simple optimal predictors, in that they provide at least the same prognostic value as the more traditional staging based on counting of involved nodes, without replacing them with a needlessly complicated alternative. They can be viewed as a per patient standardization in which the number of involved nodes is standardized

    As a kind of malignant tumor in the male genitourinary system, prostate cancer exhibits significantly increased occurrence. Prostate-specific antigen (PSA) expression can be seen in the prostate cancer, prostatitis, and other diseases, therefore, lack of diagnostic specificity. The miR-155 expression is abnormally increased in the tumors. Therefore, this study aims to explore the clinical significance of PSA combined miR-155 detection in the early diagnosis of prostate cancer. A total of 86 patients diagnosed with prostate cancer were enrolled in this study. PSA and miR-155 gene expression in tumor tissue were detected by using Real-time PCR. The serum levels of PSA were measured by using enzyme-linked immunosorbent assay (ELISA). The correlation of PSA and miR-155 expression with age, body mass index (BMI), tumor volume, tumor-node-metastasis (TNM) stage, lymph node metastasis (LNM), and other clinicopathological features were analyzed, respectively. Serum PSA expression and PSA gene in tumor tissue were significantly higher compared to that in adjacent tissues (pPSA gene and protein increased significantly with the clinical stage of TNM and decreased following the increase of grade (pPSA and miR-155 expressions were positively correlated with TNM stage, tumor volume, and LNM, and negatively correlated with grade (pPSA and miR-155 were closely related to the clinicopathological features of prostate cancer. Combined detection is helpful for the early diagnosis of prostate cancer.

  3. [Laparoscopic Proximal Gastrectomy as a Surgical Treatment for Upper Third Early Gastric Cancer].

    2017-09-25

    Recently, the incidence of upper third gastric cancer has increased, and with it the number of endoscopic submucosal dissection (ESD) procedures performed has been increasing. However, if ESD is not indicated or non-curable, surgical treatment may be necessary. In the case of lower third gastric cancer, it is possible to preserve the upper part of the stomach; however, in the case of upper third gastric cancer, total gastrectomy is still the standard treatment option, regardless of the stage. This is due to the complications associated with upper third gastric cancer, such as gastroesophageal reflux after proximal gastrectomy rather than oncologic problems. Recently, the introduction of the double tract reconstruction method after proximal gastrectomy has become one of the surgical treatment methods for upper third early gastric cancer. However, since there has not been a prospective comparative study evaluating its efficacy, the ongoing multicenter prospective randomized controlled trial (KLASS-05) comparing laparoscopic proximal gastrectomy with double tract reconstruction and laparoscopic total gastrectomy is expected to be important for determining the future of treatment of upper third early gastric cancer.

    Difficulties in coping with cancer, and the accompanying anxious and depressive symptoms, have been shown to affect the mood and the quality of life in breast cancer patients. 5-Hydroxytryptamine Transporter Gene-linked Polymorphic Region (5-HTTLPR) functional polymorphism of serotonin transporter has been shown to influence the adaptation to stressful life events. The aim of this prospective study was therefore to examine the association of 5-HTTLPR with the mental adaptation to cancer diagnosis and treatment. Forty eight consecutive patients with early mammary carcinoma were evaluated at enrolment and at follow up after one and three months. The patients were characterized psychometrically using the Hospital Anxiety and Depression Scale (HADS) and the Mini-Mental Adjustment to Cancer Scale (Mini-MAC); 5-HTTLPR allelic variants were determined using PCR-based techniques. In women with early breast cancer, the mental adaptation to the disease was associated with high scores of avoidance and anxious preoccupation of Mini-MAC, which decreased with time at follow up. Anxious preoccupation decreased with time less in patients with the S/S and S/L genetic variant of 5-HTTLPR as compared with the L/L carriers (p=0.023), indicating gene - environment interactions. These results indicate that the characterization of 5-HTTLPR allows the identification of breast cancer patients in greater risk of mental suffering, for which specific intervention may be focused; in case of drug therapy, they provide indications for the choice of most appropriate agent in a pharmacogenetic perspective

    Full Text Available Context: Data regarding health-related quality of life in breast cancer patients in the Middle East are limited with fatigue and sleep disturbance being the most distressing symptoms reported by patients treated for early breast cancer. Aims: The aim of this study was to examine the prevalence and incidence of insomnia among patients with early-stage breast cancer patients treated with chemotherapy. Subjects and Methods: This was a prospective cohort study. We enrolled patients with stage I-III breast cancer patients treated with chemotherapy at the American University of Beirut Medical Center. At three different time points (prior to, during, and following chemotherapy, we assessed the severity of sleep disturbances using the Pittsburgh Sleep Quality Index and the Insomnia Severity Index. The Institution Review Board approved the study. Results: Fifty-two patients were recruited. There was a significant increase in sleep disturbances during chemotherapy which improved to below baseline levels on completion of therapy. Prior to chemotherapy, 36% of patients reported poor sleep versus 58% during chemotherapy. The percentage of patients reporting clinical insomnia rose from 11% pretreatment to 36% during chemotherapy reflecting a significant symptomatic burden that is poorly documented and managed in routine clinical practice. Conclusions: Patients with nonmetastatic breast cancer experience an increase in sleep disturbances during the treatment phase. Physicians should be aware of the need to routinely screen for sleep disturbance in breast cancer patients undergoing chemotherapy.

    Epigenetic gene regulation has influence over a diverse range of cellular functions, including the maintenance of pluripotency, differentiation, and cellular identity, and is deregulated in many diseases, including cancer. Whereas the involvement of epigenetic dysregulation in cancer is well documented, much of the mechanistic detail involved in triggering these changes remains unclear. In the current age of genomics, the development of new sequencing technologies has seen an influx of genomic and epigenomic data and drastic improvements in both resolution and coverage. Studies in cancer cell lines and clinical samples using next-generation sequencing are rapidly delivering spectacular insights into the nature of the cancer genome and epigenome. Despite these improvements in technology, the timing and relationship between genetic and epigenetic changes that occur during the process of carcinogenesis are still unclear. In particular, what changes to the epigenome are playing a driving role during carcinogenesis and what influence the temporal nature of these changes has on cancer progression are not known. Understanding the early epigenetic changes driving breast cancer has the exciting potential to provide a novel set of therapeutic targets or early-disease biomarkers or both. Therefore, it is important to find novel systems that permit the study of initial epigenetic events that potentially occur during the first stages of breast cancer. Non-malignant human mammary epithelial cells (HMECs) provide an exciting in vitro model of very early breast carcinogenesis. When grown in culture, HMECs are able to temporarily escape senescence and acquire a pre-malignant breast cancer-like phenotype (variant HMECs, or vHMECs). Cultured HMECs are composed mainly of cells from the basal breast epithelial layer. Therefore, vHMECs are considered to represent the basal-like subtype of breast cancer. The transition from HMECs to vHMECs in culture recapitulates the epigenomic

    Cancer cachexia is a multifactorial syndrome characterized by body weight loss, atrophy of adipose tissue (AT) and systemic inflammation. However, there is limited information regarding the mechanisms of immunometabolic response in AT from cancer cachexia. Male Wistar rats were inoculated with 2 × 10 7 of Walker 256 tumor cells [tumor bearing (TB) rats]. The mesenteric AT (MeAT) was collected on d 0, 4, 7 (early stage), and 14 (cachexia stage) after tumor cell injection. Surgical biopsies for MeAT were obtained from patients who had gastrointestinal cancer with cachexia. Lipolysis showed an early decrease in glycerol release in TB d 4 (TB4) rats in relation to the control, followed by a 6-fold increase in TB14 rats, whereas de novo lipogenesis was markedly lower in the incorporation of glucose into fatty acids in TB14 rats during the development of cachexia. CD11b and CD68 were positive in TB7 and TB14 rats, respectively. In addition, we found cachexia stage results similar to those of animals in MeAT from patients: an increased presence of CD68 + , iNOS2 + , TNFα + , and HSL + cells. In summary, translational analysis of MeAT from patients and an animal model of cancer cachexia enabled us to identify early disruption in Adl turnover and subsequent inflammatory response during the development of cancer cachexia.-Henriques, F.

    Early electrocardiogram (ECG) changes after breast cancer radiotherapy (RT) have been reported, but their characteristics and associated factors are largely unknown. This study aimed to explore early RT-induced ECG changes and to compare them with echocardiography changes. Sixty eligible patients with chemotherapy-naïve left-sided and 20 with right-sided breast cancer were evaluated with echocardiography, blood samples and ECG before and after RT. RT-induced ECG changes in the anterior leads. T-Wave changes were most frequent. T-Wave decline was associated independently with patient age (β=-0.245, p=0.005), mean heart radiation dose (β=1.252, p=0.001) and global systolic strain rate change (β=7.943, p=0.002). T-Wave inversion was associated independently with mean heart radiation dose (β=0.143, pECG changes were prevalent and associated with functional and structural changes in echocardiography. ECG could be used for post-RT cardiac screening. Copyright© 2018, International Institute of Anticancer Research (Dr. George J. Delinasios), All rights reserved.

    Background Men with familial prostate cancer (PCA) and African American men are at risk for developing PCA at younger ages. Genetic markers predicting early-onset PCA may provide clinically useful information to guide screening strategies for high-risk men. We evaluated clinical information from six polymorphisms associated with early-onset PCA in a longitudinal cohort of high-risk men enrolled in PCA early detection with significant African American participation. Methods Eligibility criteria include ages 35–69 with a family history of PCA or African American race. Participants undergo screening and biopsy per study criteria. Six markers associated with early-onset PCA (rs2171492 (7q32), rs6983561 (8q24), rs10993994 (10q11), rs4430796 (17q12), rs1799950 (17q21), and rs266849 (19q13)) were genotyped. Cox models were used to evaluate time to PCA diagnosis and PSA prediction for PCA by genotype. Harrell’s concordance index was used to evaluate predictive accuracy for PCA by PSA and genetic markers. Results 460 participants with complete data and ≥1 follow-up visit were included. 56% were African American. Among African American men, rs6983561 genotype was significantly associated with earlier time to PCA diagnosis (p=0.005) and influenced prediction for PCA by the PSA (p<0.001). When combined with PSA, rs6983561 improved predictive accuracy for PCA compared to PSA alone among African American men (PSA= 0.57 vs. PSA+rs6983561=0.75, p=0.03). Conclusions Early-onset marker rs6983561 adds potentially useful clinical information for African American men undergoing PCA risk assessment. Further study is warranted to validate these findings. Impact Genetic markers of early-onset PCA have potential to refine and personalize PCA early detection for high-risk men. PMID:22144497

    Full Text Available Biomarkers for the early detection of cancer in the general population have to perform with high sensitivity and specificity in order to prevent the costs associated with over-diagnosis. There are only a few current tissue or blood markers that are recommended for generalized cancer screening. Despite the recognition that combinations of multiple biomarkers will likely improve their utility, biomarker panels are usually limited to a single class of molecules. Tissues and body fluids including plasma and serum contain not only proteins, DNA and microRNAs that are differentially expressed in cancers but further cancer specific information might be gleaned by comparing different classes of biomolecules. For example, the level of a certain microRNA might be related to the level of a particular protein in a cancer specific manner. Proteins might have cancer-specific post-translational modifications (e.g., phosphorylation or glycosylation or lead to the generation of autoantibodies. Most currently approved biomarkers are glycoproteins. Autoantibodies can be produced as a host’s early surveillance response to cancer-specific proteins in pre-symptomatic and pre-diagnostic stages of cancer. Thus, measurement of the level of a protein, the level of its glycosylation or phosphorylation and whether autoantibodies are produced to it can yield multi-dimensional information on each protein. We consider specific proteins that show consistent cancer-specific changes in two or three of these measurements to be “hybrid markers”. We hypothesize these markers will suffer less variation between different individuals since one component can act to “standardize” the other measurement. As a proof of principle, a 180 plasma sample set consisting of 120 cases (60 colon cancers and 60 adenomas and 60 controls were analyzed using our high-density antibody array for changes in their protein, IgG-complex and sialyl-Lewis A (SLeA modified proteins.

    To investigate clinicopathological features of early stage gastric cancer with enteroblastic differentiation (GCED). We retrospectively investigated data on 6 cases of early stage GCED and 186 cases of early stage conventional gastric cancer (CGC: well or moderately differentiated adenocarcinoma) who underwent endoscopic submucosal dissection or endoscopic mucosal resection from September 2011 to February 2015 in our hospital. GCED was defined as a tumor having a primitive intestine-like structure composed of cuboidal or columnar cells with clear cytoplasm and immunohistochemical positivity for either alpha-fetoprotein, Glypican 3 or SALL4. The following were compared between GCED and CGC: age, gender, location and size of tumor, macroscopic type, ulceration, depth of invasion, lymphatic and venous invasion, positive horizontal and vertical margin, curative resection rate. Six cases (5 males, 1 female; mean age 75.7 years; 6 lesions) of early gastric cancer with a GCED component and 186 cases (139 males, 47 females; mean age 72.7 years; 209 lesions) of early stage CGC were investigated. Mean tumor diameters were similar but rates of submucosal invasion, lymphatic invasion, venous invasion, and non-curative resection were higher in GCED than CGC (66.6% vs 11.4%, 33.3% vs 2.3%, 66.6% vs 0.4%, 83.3% vs 11% respectively, P < 0.01). Deep submucosal invasion was not revealed endoscopically or by preoperative biopsy. Histologically, in GCED the superficial mucosal layer was covered with a CGC component. The GCED component tended to exist in the deeper part of the mucosa to the submucosa by lymphatic and/or venous invasion, without severe stromal reaction. In addition, Glypican 3 was the most sensitive marker for GCED (positivity, 83.3%), immunohistochemically. Even in the early stage GCED has high malignant potential, and preoperative diagnosis is considered difficult. Endoscopists and pathologists should know the clinicopathological features of this highly malignant type

    Directory of Open Access Journals (Sweden)

    Full Text Available For early-stage breast cancers mastectomy is an aggressive form of treatment. Therefore, there is a need for new treatment strategies that can enhance the use of lumpectomy by eliminating residual cancer cells with limited side effects to reduce local recurrence. Although, various radiotherapy-based methods have been developed, residual cells are found in 20-55% of the time at the first operation. Furthermore, some current treatment methods result in poor cosmesis. For the last decade, the authors have been exploring the use of polymeric composite materials in single and multi-modal implantable biomedical devices for post-operative treatment of breast cancer. In this paper, the concept and working principles of the devices, as well as selected results from experimental and numerical investigations, are presented. The results show the potential of the biomedical implants for cancer treatment.

    To assess the diagnostic accuracy of the double contrast upper gastrointestinal series (UGI), we have done a retrospective analysis of pathologically proven 92 cases of early gastric cancer (EGC) during the period between March 1981 and February 1986. The results were as follows: 1. The diagnostic accuracy of EGC was 66% on UGI and 62% on fiberscopy. 2. The radiological diagnosis (UGI) of 92 cases was EGC in 61 cases, advanced cancer in 15 cases, cancer invaded in the muscle layer in 7 cases (PM cancer), benign ulcer in 8 cases and polyp in 1 case. 3. The commonest type was type IIc (40%), and the second commonest type was IIc + III. As many EGC's present with ulceration, any ulcerating lesion should be carefully evaluated keeping the possibility of EGC in mind. 4. The rate of lymph node metastasis was 7%, and higher in EGC's with submucosal invasion, in depressed and large lesions

    1996-01-01

    Purpose: This study was initiated to determine the maximum tolerable dose of hyperfractionated radiation in patients with locally advanced prostate cancer. Materials and Methods: Forty-nine patients with locally advanced prostate cancer (T3-T4 Nx, 0, 1 M0 and/or Gleason Score ≥ 8) were treated on the first two steps of a prospective dose-escalation study using hyperfractionated conformal radiotherapy. The first 25 patients received a minimum dose of 78Gy to the clinical tumor volume (CTV) including the prostate, seminal vesicle and a 5mm margin at 1.3Gy b.i.d. The second group (24 patients) received a minimum dose to the CTV of 82.8Gy at 1.15Gy b.i.d. Twenty eight patients received neo-adjuvant hormonal therapy in conjunction with their radiation (8 of 25 patients at 78Gy and 20 of 24 patients at 82.8Gy). Toxicity was scored according to the RTOG grading scale. Efficacy was evaluated by PSA levels and ultrasound guided biopsies. Median follow up was 36 and 18 months for the 78Gy and 82.8Gy dose levels, respectively. Results: No grade 3 or 4 gastrointestinal (GI) or genitourinary (GU) toxicity was noted. At 36 months, the actuarial probability of Grade 2 GI and GU toxicity were 16 and 20%, respectively. Twelve to 18 months following radiation, 41 patients (86%) underwent ultrasound guided biopsy. At 78Gy, 60% of 20 patients had a biopsy which was negative or showed a marked therapeutic effect. At 82.8Gy, these combined rates were 95% in the 21 patients who had biopsies. Nine patients (50%) who did not receive neo-adjuvant hormones had positive biopsies. No patient who received neo-adjuvant hormones plus 78Gy (5 patients) or 82.8Gy (18 patients) had a positive biopsy. Conclusion: Proceeding to the next dose level (87.4Gy) was justified by the lack of severe chronic toxicity. However, in view of the high rate of histologic sterilization when hyperfractionated irradiation was given in conjunction with neo-adjuvant hormonal therapy, it was felt to be unethical to

    Full Text Available INTRODUCTION Mortality and morbidity associated with head and neck cancers have decreased to a great extent in many developed countries of the world due to early diagnosis and treatment with advances in surgical techniques and better availability of radiotherapist and oncologists. But the situation in developing countries like India is quite different. AIMS AND OBJECTIVES This study was conducted amongst the patients attending the Otolaryngology department of a teaching hospital in Kolkata to find the incidence of various types and sites of head and neck cancer, to assess time delay from the date of onset of symptom to the final disease confirmation in relation to patients’ demographic profile, to assess time delay in histopathological diagnosis after reaching a tertiary care setup and also to correlate tobacco consumption and alcohol intake as risk factors for head and neck cancer and to note the reasons for late presentation, as described by the patient. MATERIALS AND METHODS The descriptive study was conducted at a tertiary level teaching hospital, in the Department of Otorhinolaryngology for a period from August 2013 to August 2015 with a study population of 133.  OBSERVATIONS  An average time lag from the onset of symptom to final diagnosis as malignancy was found to be 6 months to one year in nearly 72% of cases. Most of the patients were uneducated males of more than 50 years of age, hailing from rural areas. Cancer larynx was found to be the commonest of all head and neck cancers (31.6%. More than 65% of the patients were addicted to tobacco chewing or smoking or consumption of alcohol.  DISCUSSION  Poverty, lack of education, poor communication, lack of health care infrastructure in rural areas, community awareness about various risk factors, lack of effective health policy to achieve early diagnosis of head neck cancer were common factors related to delay in diagnosis.  CONCLUSION  Tobacco use and alcohol intake are the

    Early-onset baldness has been linked to prostate cancer; however, little is known about this relationship in African-Americans who are at elevated prostate cancer risk. We recruited 219 African-American controls and 318 African-American prostate cancer cases. We determined age-stratified associations of baldness with prostate cancer occurrence and severity defined by high stage (T3/T4) or high grade (Gleason 7+.) Associations of androgen metabolism genotypes (CYP3A4, CYP3A5, CYP3A43, AR-CAG, SRD5A2 A49T, and SRD5A2 V89L), family history, alcohol intake, and smoking were examined by baldness status and age group by using multivariable logistic regression models. Baldness was associated with odds of prostate cancer [OR = 1.69; 95% confidence interval (CI), 1.05-2.74]. Frontal baldness was associated with high-stage (OR = 2.61; 95% CI, 1.10-6.18) and high-grade (OR = 2.20; 95% CI, 1.05-4.61) tumors. For men diagnosed less than the age of 60 years, frontal baldness was associated with high stage (OR = 6.51; 95% CI, 2.11-20.06) and high grade (OR = 4.23; 95% CI, 1.47-12.14). We also observed a suggestion of an interaction among smoking, median age, and any baldness (P = 0.02). We observed significant associations between early-onset baldness and prostate cancer in African-American men. Interactions with age and smoking were suggested in these associations. Studies are needed to investigate the mechanisms influencing the relationship between baldness and prostate cancer in African-American men. African-American men present with unique risk factors including baldness patterns that may contribute to prostate cancer disparities.

    Early lung cancers associated with cystic airspaces are increasingly being recognized as a cause of delayed diagnoses-owing to data gathered from screening trials and encounters in routine clinical practice as more patients undergo serial imaging. Several morphologic subtypes of cancers associated with cystic airspaces exist and can exhibit variable patterns of progression as the solid elements of the tumor grow. Current understanding of the pathogenesis of these malignancies is limited, and the numbers of cases reported in the literature are small. However, several tumor cell types are represented in these lesions, with adenocarcinoma predominating. The features of cystic airspaces differ among cases and include emphysematous bullae, congenital or fibrotic cysts, subpleural blebs, bronchiectatic airways, and distended distal airspaces. Once identified, these cystic lesions pose management challenges to radiologists in terms of distinguishing them from benign mimics of cancer that are commonly seen in patients who also are at increased risk of lung cancer. Rendering a definitive tissue-based diagnosis can be difficult when the lesions are small, and affected patients tend to be in groups that are at higher risk of requiring biopsy or resection. In addition, the decision to monitor these cases can add to patient anxiety and cause the additional burden of strained departmental resources. The authors have drawn from their experience, emerging evidence from international lung cancer screening trials, and large databases of lung cancer cases from other groups to analyze the prevalence and evolution of lung cancers associated with cystic airspaces and provide guidance for managing these lesions. Although there are insufficient data to support specific management guidelines similar to those for managing small solid and ground-glass lung nodules, these data and guidelines should be the direction for ongoing research on early detection of lung cancer. © RSNA, 2018.

    Full Text Available Dietary energy restriction may protect against cancer. In parts of The Netherlands, mostly in larger cities, periods of chronically impaired nutrition and even severe famine (Hunger Winter 1944-1945 existed during the 1930s and World War II (1940-1945. We studied the association between energy restriction during childhood and early adulthood on the risk of ovarian cancer later in life. In 1986, the Netherlands Cohort Study was initiated. A self-administered questionnaire on dietary habits and other cancer risk factors was completed by 62,573 women aged 55-69 years at baseline. Follow-up for cancer was established by record linkage to the Netherlands Cancer Registry. After 16.3 years of follow-up, 364 invasive epithelial ovarian cancer cases and 2220 subcohort members (sampled from the total cohort directly after baseline with complete information confounders were available for case-cohort analyses. In multivariable analysis, ovarian cancer risk was lower for participants with an unemployed father during the 1930s (Hazard Ratio (HR, 0.70; 95% Confidence Interval (CI, 0.47-1.06 compared to participants with an employed father as well as for participants living in a city during World War II (HR, 0.69; 95% CI, 0.54-0.90 compared to participants living in the country-side. Residence in a Western City during the famine (Hunger Winter was not associated with a decreased risk. Our results show a relation between proxy variables for modest energy restriction over a longer period of time during childhood or early adulthood and a reduced ovarian cancer risk.

    Results of the National Program of Breast Cancer Early Detection in Brod-Posavina County during the 2006-2012 period are presented. Response rate in two National Program cycles, cancers detected according to factors such as first and last menstruation, age at cancer detection, deliveries and mammography findings according to the Breast Imaging Reporting and Data System (BI-RADS) before diagnosis verification were analyzed. Data were obtained from the software connecting Public Health Institutes via Ministry of Health server and questionnaires filled out by the women presenting for screening and processed by the method of descriptive statistics. Mammography findings were classified according to the BI-RADS classification. In two National Program cycles during the 2006-2012 period, women aged 50-69 were called for mammography screening. In the first cycle, the response rate in Brod-Posavina County was 53.2%, with 71 cancers detected at a mean age of 61.3 years. In the second cycle, the response rate was 57.0%, with 44 cancers detected at a mean age of 62.5 years. In the first and second cycles, there were 21.1% and 14.3% of mammography findings requiring additional work-up (BI-RADS 0), respectively. Particular risk factors such as early menarche, late menopause, parity, positive family history and presence of benign breast lesions were not demonstrated in women with verified cancer. There was no increase in the incidence of breast cancer per 100,000 inhabitants in the Brod-Posavina County following implementation of the National Program. In conclusion, efforts should be focused on increasing public health awareness, ensuring appropriate professional staff engaged in screening, and improving medical care in order to reduce the time elapsed from establishing suspicion to confirming the diagnosis of breast cancer.

    Most colorectal cancers show either microsatellite or chromosomal instability. A subset of colorectal cancers, especially those diagnosed at young age, is known to show neither of these forms of genetic instability and thus might have a distinct pathogenesis. Colorectal cancers diagnosed at young age are suggestive for hereditary predisposition. We investigate whether such early-onset microsatellite and chromosomally stable colorectal cancers are a hallmark of a genetic susceptibility syndrome. The ploidy status of microsatellite stable (familial) colorectal cancers of patients diagnosed before age 50 (n = 127) was analyzed in relation to the histopathological characteristics and family history. As a control the ploidy status of sporadic colorectal cancer, with normal staining of mismatch repair proteins, diagnosed at the age of 69 years or above (n = 70) was determined. A diploid DNA content was used as a marker for chromosomal stability. Within the group of patients with (familial) early onset microsatellite stable colorectal cancer the chromosomally stable tumors did not differ from chromosomally unstable tumors with respect to mean age at diagnosis, fulfillment of Amsterdam criteria or pathological characteristics. Segregation analysis did not reveal any family with microsatellite and chromosomally stable colorectal cancer in 2 relatives. The prevalence of microsatellite and chromosomally stable colorectal cancer was not significantly different for the early and late onset group (28 and 21%, respectively). We find no evidence that early-onset microsatellite and chromosomally stable colorectal cancer is a hallmark of a hereditary colorectal cancer syndrome. (c) 2007 Wiley-Liss, Inc.

    In 1982 a prospective, multicentre randomized trial of breast preserving surgery for invasive histopathological stage I breast cancer was started in the Uppsala-Oerebro health care region in Sweden. After identical preoperative investigation and surgical treatment, patients are randomly allocated to receive postoperative radiation with 54 Gy to the remaining breast for five weeks, or to serve as controls. The primary aim of the trial is to determine whether a standardized surgical technique aiming at local tumour radicality can reduce the rate of local recurrence to an acceptable level without postoperative radiotherapy. In December 1987 a second trial was initiated, with an almost identical design but including women with tumours mammographically 21-30 mm in diameter and with histopathologically negative nodes. The first trial is near the termination of patient accrual. Studies of the cosmetic result and of the psychosocial adjustment after breast conserving therapy as compared with mastectomy have been coupled to the trials. Among 263 patients who answered a questionnaire, 96.5% found the new appearance of the treated breast good or acceptable. The psychosocial adjustment was assessed in semi-structured interviews 4 and 13 months postoperatively in 99 women, 37 of whom underwent breast conserving surgery and the remainder modified radical mastectomy. There was a consistent but statistically non-significant tendency for the conservatively treated women to adjust better. Overall 5% of the women in the conservatively treated group and 22% of the mastectomized women are still suffering substantial psychosocial disturbance after 13 months. (orig.)

    Cancer-induced muscle wasting, which commonly occurs in cancer cachexia, is characterized by impaired quality of life and poor patient survival. To identify an appropriate treatment, research on the mechanism underlying muscle wasting is essential. Thus far, studies on muscle wasting using cancer cachectic models have generally focused on early cancer cachexia (ECC), before severe body weight loss occurs. In the present study, we established models of ECC and late cancer cachexia (LCC) and compared different stages of cancer cachexia using two cancer cachectic mouse models induced by colon-26 (C26) adenocarcinoma or Lewis lung carcinoma (LLC). In each model, tumor-bearing (TB) and control (CN) mice were injected with cancer cells and PBS, respectively. The TB and CN mice, which were euthanized on the 24th day or the 36th day after injection, were defined as the ECC and ECC-CN mice or the LCC and LCC-CN mice. In addition, the tissues were harvested and analyzed. We found that both the ECC and LCC mice developed cancer cachexia. The amounts of muscle loss differed between the ECC and LCC mice. Moreover, the expression of some molecules was altered in the muscles from the LCC mice but not in those from the ECC mice compared with their CN mice. In conclusion, the molecules with altered expression in the muscles from the ECC and LCC mice were not exactly the same. These findings may provide some clues for therapy which could prevent the muscle wasting in cancer cachexia from progression to the late stage.

    There are no reliable blood biomarkers to detect early lung cancer. We used a novel strategy that allows discovery of differentially present proteins against a complex and variable background. Mass spectrometry analyses of paired pulmonary venous-radial arterial blood from 16 lung cancer patients were applied to identify plasma proteins potentially derived from the tumor microenvironment. Two differentially expressed proteins were confirmed in 64 paired venous-arterial blood samples using an immunoassay. Twenty-eight pre- and postsurgical resection peripheral blood samples and two independent, blinded sets of plasma from 149 participants in a lung cancer screening study (49 lung cancers and 100 controls) and 266 participants from the National Heart Lung and Blood Institute Lung Health Study (45 lung cancer and 221 matched controls) determined the accuracy of the two protein markers to detect subclinical lung cancer. Connective tissue-activating peptide III (CTAP III)/ neutrophil activating protein-2 (NAP-2) and haptoglobin were identified to be significantly higher in venous than in arterial blood. CTAP III/NAP-2 levels decreased after tumor resection (P = .01). In two independent population cohorts, CTAP III/NAP-2 was significantly associated with lung cancer and improved the accuracy of a lung cancer risk prediction model that included age, smoking, lung function (FEV(1)), and an interaction term between FEV(1) and CTAP III/NAP-2 (area under the curve, 0.84; 95% CI, 0.77 to 0.91) compared to CAPIII/NAP-2 alone. We identified CTAP III/NAP-2 as a novel biomarker to detect preclinical lung cancer. The study underscores the importance of applying blood biomarkers as part of a multimodal lung cancer risk prediction model instead of as stand-alone tests.

    Breast cancer is the most common malignancy in women and affects approximately 1 out of 8 females in the US. Risk of developing breast cancer is strongly influenced by genetic factors. Germ-line mutations in BRCA1 and BRCA2 genes are associated with 5-10% of breast cancer incidence. To reduce the risk of developing cancer and to increase the likelihood of early detection, carriers of BRCA1 or BRCA2 mutations are offered surveillance programs and effective preventive medical interventions. Identification of founder mutations of BRCA1/2 in high risk communities can have a significant impact on the management of hereditary cancer at the level of the national healthcare systems, making genetic testing more affordable and cost-effective. BRCA1 and BRCA2 mutations in breast cancer patients have not been characterized in the Uzbek population. This pilot study aimed to investigate the contribution of BRCA1 and BRCA2 mutation to early onset and familial cases of breast cancer in Uzbekistan. A total of 67 patients with breast cancer and 103 age-matched disease free controls were included in this study. Utilizing SYBR Green based real-time allele-specific PCR, we have analyzed DNA samples of patients with breast cancer and disease free controls to identify the following BRCA1 and BRCA2 mutations: BRCA1 5382insC, BRCA1 4153delA, BRCA1 185delAG, BRCA1 300T>G, BRCA2 6174delT. Three unrelated samples (4.5%) were found to be positive for the heterozygous 5382insCBRCA1 mutation, representing a possible founder mutation in the Uzbek population, supporting the need for larger studies examining the contribution of this mutation to breast cancer incidence in Uzbekistan. We did not find BRCA1 4153delA, BRCA1 185delAG, BRCA1 300T>G, and BRCA2 6174delT mutations. This preliminary evidence suggests a potential contribution of BRCA1 5382insC mutation to breast cancer development in Uzbek population. Taking into account a high disease penetrance in carriers of BRCA1 mutation, it seems

    Approximately 5-10% of breast cancers are attributable to genetic susceptibility. Mutations in the BRCA1 and BRCA2 genes are the best known genetic factors to date. The goal of this study was to determine the structure and distribution of haplotypes of the BRCA1 and BRCA2 genes in early-onset breast cancer patients. We enrolled 70 patients diagnosed with early-onset breast cancer. A total of 21 SNPs (11 on BRCA1 and 10 on BRCA2) and 1 dinucleotide deletion on BRCA1 were genotyped using nested allele-specific PCR methods. Linkage disequilibrium (LD) analysis was conducted, and haplotypes were deduced from the genotype data. Two tightly linked LD blocks were observed on each of the BRCA1 and BRCA2 genes. Variant-free haplotypes (TAT-AG for BRCA1 and ATA-AAT for BRCA2) were observed at a frequency of more than 50% on each gene along with variable frequencies of derived haplotypes. The variant 3'-subhaplotype CGC displayed strong LD with 5'-subhaplotypes GA, AA, and GG on BRCA1 gene. Haplotypes ATA-AGT, ATC-AAT, and ATA-AAC were the variant haplotypes frequent on BRCA2 gene. Although the clinical significance of these derived haplotypes has not yet been established, it is expected that some of these haplotypes, especially the less frequent subhaplotypes, eventually will be shown to be indicative of a predisposition to early-onset breast cancer.

    Breast cancer is one of the main causes of women death worldwide. Breast tumor is an early stage of cancer that locates in cells of a human breast. As there is no remedy, early detection is crucial. Towards this, Ultra-Wideband (UWB) is a prominent candidate. It is a wireless communication technology which can achieve high bandwidth with low power utilization. UWB is suitable to be used for short range communication systems including breast cancer detection since it is secure, non-invasive and human health friendly. This paper presents the low-cost and non-invasive early breast cancer detection strategy using UWB sensor (or antenna). Emphasis is given here to detect breast tumor in 2D and 3D environments. The developed system consisted of hardware and software. Hardware included UWB transceiver and a pair of home-made directional sensor/antenna. The software included feed-forward back propagation Neural Network (NN) module to detect the tumor existence, size and location along with soft interface between software and hardware. Forward scattering technique was used by placing two sensors diagonally opposite sides of a breast phantom. UWB pulses were transmitted from one side of phantom and received from other side, controlled by the software interface in PC environment. Collected received signals were then fed into the NN module for training, testing and validation. The system exhibited detection efficiency on tumor existence, location (x, y, z), and size were approximately 100%, (78.17%, 70.66%, 92.46%), 85.86% respectively. The proposed UWB based early breast cancer detection system could be more practical with low-cost, user friendly and non-harmful features. This project may help users to monitor their breast health regularly at their home.

    The presence of axillary lymph node metastases is an important prognostic factor in breast cancer. Sentinel lymph node biopsy (SLNB) is an emerging method for the staging of the axilla. It is hoped that with SLNB, the morbidity from axillary lymph node dissection (ALND) can be avoided without compromising the staging and management of early breast cancer. However, only patients found to be SLNB negative benefit from this procedure, as those with positive SLNB may still require ALND. Our objective is to study the various clinico-pathological factors to find predictive factors for axillary lymph node involvement in early breast cancer. It is hoped that with these factors, we will be better able to identify groups of patients most likely to benefit from SLNB. A retrospective study of 380 early breast cancer cases (stage T1 and T2, N0, N1, M0) in women treated in the Department of General Surgery, Tan Tock Seng Hospital, between January 1999 and August 2002, was conducted. Incidence of nodal metastases was correlated with clinico-pathological factors, and analysed by univariate and multivariate analyses. Approximately 35 percent of the 380 cases of early breast cancer had nodal metastases. Multivariate analyses revealed four independent predictors of node positivity: tumour size (p-value equals 0.0001), presence of lymphovascular invasion (p-value is less than 0.0001), tumours with histology other than invasive ductal or lobular carcinoma (p-value equals 0.04), and presence of progesterone receptors (p-value equals 0.05). We have found independent preoperative predictive factors in our local population for the presence of nodal metastases. This information can aid patient selection for SLNB and improve patient counselling.

    A key design consideration in developing contrast agents is obtaining distinct, multiple signal changes in diseased tissue. Plasmonic gold nanoparticles (Au NPs) have been developed as contrast agents due to their strong surface plasmon resonance (SPR). This study aims to demonstrate that stimuli-responsive plasmonic Au nanoclusters (Au NCs) can be used as a contrast agent for optical coherence tomography (OCT) in detecting early-stage cancer. Au NPs were clustered via acid-cleavable linkers to synthesize Au NCs that disassemble under mildly acidic conditions into individual Au NPs, simultaneously diminishing SPR effect (quantified by scattering intensity) and increasing Brownian motion (quantified by Doppler variance). The acid-triggered morphological and accompanying optico-physical property changes of the acid-disassembling Au NCs were confirmed by TEM, DLS, UV/Vis, and OCT. Stimuli-responsive Au NCs were applied in a hamster check pouch model carrying early-stage squamous carcinoma tissue. The tissue was visualized by OCT imaging, which showed reduced scattering intensity and increased Doppler variance in the dysplastic tissue. This study demonstrates the promise of diagnosing early-stage cancer using molecularly programmable, inorganic nanomaterial-based contrast agents that are capable of generating multiple, stimuli-triggered diagnostic signals in early-stage cancer.[Figure not available: see fulltext.

    Investigation of clinicians' understanding of early menopause diagnosis/management in women with breast cancer. A cross-sectional study of 176 randomly recruited Australian clinicians (35 gynecologists, 35 endocrinologists, 36 oncologists, 35 breast surgeons and 35 general practitioners (GPs)) involved in the care of women with breast cancer. This questionnaire study utilized an index case to assess understanding of early menopause diagnosis and management. Analysis involved descriptive statistics, χ² tests and Student's t-test. Significant differences between clinician groups regarding diagnostic criteria for early menopause were observed; gynecologists, endocrinologists and GPs selected amenorrhea > 12 months, whereas oncologists and breast surgeons selected elevated serum follicle stimulating hormone level (p breast surgeons (57%), gynecologists (54%) and endocrinologists (49%) compared to oncologists (28%) or GPs (9%) (p = 0.0001). Exercise (63%) and nutrition (66%) were selected by most gynecologists for treatment of hot flushes, whereas endocrinologists (91%), oncologists (94%), breast surgeons (69%) and GPs (63%) prescribed venlafaxine. Hormone therapy was mainly prescribed by breast surgeons (43%) compared to other groups (p = 0.001). Most clinicians reported that the main problem with menopausal therapies was failure to resolve hot flushes. Exercise, lifestyle and stress management were recommended by all clinician groups for treatment of anxiety/depression. This exploratory study demonstrated a lack of consensus between clinician groups in their investigation, diagnosis and management of early menopause in women with breast cancer, with implications for both diagnosis and treatment.

    Innovation leading to significant advances in research and subsequent translation to clinical practice is urgently necessary in early detection of sporadic pancreatic cancer. Addressing this need, the Early Detection of Sporadic Pancreatic Cancer Summit Conference was conducted by Kenner Family Research Fund in conjunction with the 2014 American Pancreatic Association and Japan Pancreas Society Meeting. International interdisciplinary scientific representatives engaged in strategic facilitated conversations based on distinct areas of inquiry: Case for Early Detection: Definitions, Detection, Survival, and Challenges; Biomarkers for Early Detection; Imaging; and Collaborative Studies. Ideas generated from the summit have led to the development of a Strategic Map for Innovation built upon 3 components: formation of an international collaborative effort, design of an actionable strategic plan, and implementation of operational standards, research priorities, and first-phase initiatives. Through invested and committed efforts of leading researchers and institutions, philanthropic partners, government agencies, and supportive business entities, this endeavor will change the future of the field and consequently the survival rate of those diagnosed with pancreatic cancer.

    Optimal therapy for adenocarcinoma of the prostate is controversial. Numerous options are available, however, comparison of results is difficult in view of the insufficiency of phase III randomized trials comparing alternative treatment strategies. These options include such strategies as no curative therapy (so-called watchful waiting), radiotherapy (external and/or internal), cryotherapy, or radical prostatectomy. Clearly, a broad spectrum of clinical approaches. When reported experiences involving radiation therapy and radical prostatectomy are compared, surgical patients tend to be younger, of earlier stage, of higher performance status, and have lower pre-therapy PSA. These prognostic factors influence the probability of disease control, and since patient selection can have a profound impact on results reporting, these issues need to be carefully controlled. A review of patients who are potentially candidates for surgery at the University of Michigan treated with conformal therapy external beam treatment, indicates that these relatively early patients are doing well. These issues will be elaborated upon further during the presentation

    Lung cancer is one of the most abundant causes of the cancerous deaths worldwide. It has low survival rate mainly due to the late diagnosis. With the hardware advancements in computed tomography (CT) technology, it is now possible to capture the high resolution images of lung region. However, it needs to be augmented by efficient algorithms to detect the lung cancer in the earlier stages using the acquired CT images. To this end, we propose a two-step algorithm for early detection of lung cancer. Given the CT image, we first extract the patch from the center location of the nodule and segment the lung nodule region. We propose to use Otsu method followed by morphological operations for the segmentation. This step enables accurate segmentation due to the use of data-driven threshold. Unlike other methods, we perform the segmentation without using the complete contour information of the nodule. In the second step, a deep convolutional neural network (CNN) is used for the better classification (malignant or benign) of the nodule present in the segmented patch. Accurate segmentation of even a tiny nodule followed by better classification using deep CNN enables the early detection of lung cancer. Experiments have been conducted using 6306 CT images of LIDC-IDRI database. We achieved the test accuracy of 84.13%, with the sensitivity and specificity of 91.69% and 73.16%, respectively, clearly outperforming the state-of-the-art algorithms.

    Objective: To study the efficacy and toxicity of the cyberknife in the treatment of medically inoperable patients with early stage lung cancer. Methods: From September 2006 to July 2007,17 patients with clinical stage I a-I b lung cancer were treated with cyberknife at Tianjin Cancer Hospital. Of the 11 patients receiving CT guided biopsy, 3 were squamous cell cancer and 8 were adenocarcinoma. Six patients refused intrusive operation and were diagnosed by PET-CT scan. All patients were medically inoperable evaluated by a thoracic surgeon. The PTV=GTV + 3-5 mm, and the median volume of PTV was 36 cm 3 (6-82 cm 3 ). The median total prescription dose was 50 Gy(45-60 Gy) at 3-5 fractions. Results: The median follow-up time was 7 months(3-11 months). All the patients finished the treatment and were alive by the last follow-up. Slight fatigue was the most common complain. Evaluated by CT scan, 13 were complete response and 4 were partial response. No recurrence, progression or distant metastasis occurred. There were 3 patients with grade I granulocytopenia, 3 grade I pneumonitis and 1 grade II pneumonitis. Conclusions: The cyberknife radiosurgery treatment in early stage lung cancer shows a high rate of local control and minimal toxicity. Long time follow-up is necessary to evaluate the survival data and late toxicity. (authors)

    Colorectal cancer is treatable and curable when detected at early stages. However there is a lack of less invasive and more specific screening and diagnosis methods which would facilitate its prompt identification. Blood circulating autoantibodies which are immediately produced by the immune system at tumor appearance have become valuable biomarkers for preclinical diagnosis of cancer. In this work, we present the rapid and label-free detection of colorectal cancer autoantibodies directly in blood serum or plasma using a recently developed nanoplasmonic biosensor. Our nanoplasmonic device offers sensitive and real-time quantification of autoantibodies with excellent selectivity and reproducibility, achieving limits of detection around 1 nM (150-160 ng mL(-1)). A preliminary evaluation of clinical samples of colorectal cancer patients has shown good correlation with ELISA. These results demonstrate the reliability of the nanobiosensor strategy and pave the way towards the achievement of a sensitive diagnostic tool for early detection of colorectal cancer.

    In Mexico, a woman dies of cervical-uterine cancer every 2 hours, indicating a low impact by the national program for early detection of this cancer, principally because of problems related to quality and coverage. Through a qualitative study, we identified the principal barriers to use of the detection program from the point of view of actual and potential program users. Four focus groups were organized in standard conditions in Mexico City (urban, developed) and in the southern state of Oaxaca (rural, economically disadvantaged area). Participants were either women with at least one previous Papanicolaou (Pap) test or women who had never had the test. Barriers to Pap test use included (1) lack of knowledge about cervical-uterine cancer etiology, (2) not knowing that the Pap test exists, (3) the conception that cancer is an inevitably fatal disease, (4) problems in doctor/medical institution-patient relationships, (5) giving priority to unmet needs related to extreme poverty, (6) opposition by the male sexual partner, (7) rejection of the pelvic examination, (8) long waits for sample collection and receiving results, and (9) perceived high costs for care. To increase coverage of the early detection program for cervical-uterine cancer in Mexico, the needs, perceptions, and beliefs of women and their partners must be taken into account when developing policy and planning, given the role these factors play in the decision-making process that leads to their participation or nonparticipation in this program.

    With early detection, five year survival rates for ovarian cancer are over 90%, yet no effective early screening method exists. Emerging consensus suggests that perhaps over 50% of the most lethal form of the disease, high grade serous ovarian cancer, originates in the Fallopian tube. Cancer changes molecular concentrations of various endogenous fluorophores. Using specific excitation wavelengths and emissions bands on a Multispectral Fluorescence Imaging (MFI) system, spatial and spectral data over a wide field of view can be collected from endogenous fluorophores. Wavelength specific reflectance images provide additional information to normalize for tissue geometry and blood absorption. Ratiometric combination of the images may create high contrast between neighboring normal and abnormal tissue. Twenty-six women undergoing oophorectomy or debulking surgery consented the use of surgical discard tissue samples for MFI imaging. Forty-nine pieces of ovarian tissue and thirty-two pieces of Fallopian tube tissue were collected and imaged with excitation wavelengths between 280 nm and 550 nm. After imaging, each tissue sample was fixed, sectioned and HE stained for pathological evaluation. Comparison of mean intensity values between normal, benign, and cancerous tissue demonstrate a general trend of increased fluorescence of benign tissue and decreased fluorescence of cancerous tissue when compared to normal tissue. The predictive capabilities of the mean intensity measurements are tested using multinomial logistic regression and quadratic discriminant analysis. Adaption of the system for in vivo Fallopian tube and ovary endoscopic imaging is possible and is briefly described.

    The esophageal cancer has a tendency to transfer to another part of the body and the surgical operation itself sometimes gives high risk in vital function because many delicate organs exist near the esophagus. So the esophageal cancer is a disease with a high mortality. So, in order to lead a higher survival rate five years after the cancer's treatment, the investigation of the diagnosis methods or techniques of the cancer in an early stage and support the therapy are required. In this study, we performed the ex vivo experiments to obtain the Raman spectra from normal and early-stage tumor (stage-0) human esophageal sample by using Raman spectroscopy. The Raman spectra are collected by the homemade Raman spectrometer with the wavelength of 785 nm and Raman probe with 600-um-diameter. The principal component analysis (PCA) is performed after collection of spectra to recognize which materials changed in normal part and cancerous pert. After that, the linear discriminant analysis (LDA) is performed to predict the tissue type. The result of PCA indicates that the tumor tissue is associated with a decrease in tryptophan concentration. Furthermore, we can predict the tissue type with 80% accuracy by LDA which model is made by tryptophan bands.

    Currently, limited literature addresses Arab American women's responses to the impact of breast cancer and its treatments. The objective of the study was to understand the experience of being diagnosed with and undergoing surgical treatment for early-stage breast cancer among Arab American women. A qualitative interpretive phenomenological research design was used for this study. A purposive sample of 10 Arab American women who were surgically treated for early-stage breast cancer in the United States was recruited. Data were collected using individual interviews and analyzed using the Heideggerian hermeneutical methodology. Arab American women accepted breast cancer diagnosis as something in God's hands that they had no control over. Although they were content with God's will, the women believed that the diagnosis was a challenge that they should confront. The women confronted this challenge by accessing the healthcare system for treatment, putting trust in their physicians, participating when able in treatment decisions, using religious practices for coping, maintaining a positive attitude toward the diagnosis and the treatment, and seeking information. Arab American women's fatalistic beliefs did not prevent them from seeking care and desiring treatment information and options when diagnosed with breast cancer. It is important that healthcare providers encourage patients to express meanings they attribute to their illness to provide them with appropriate supportive interventions. They should also individually assess patients' decision-making preferences, invite them to participate in decision making, and provide them with tailored means necessary for such participation without making any assumptions based on patients' ethnic/cultural background.

In particular, the overexpression of the human epidermal growth factor receptor 2 (HER2 by tumor cells provided a specific target in these HER2-positive tumors. The development of the monoclonal antibody trastuzumab, and its approval in 1998 for the treatment of patients with metastatic disease, radically changed the natural history of this aggressive subtype of breast cancer. These findings provided strong support for the continuous research in targeting the HER2 pathway and implementing the development of new anti-HER2 targeted agents. Besides trastuzumab, a series of other anti-HER2 agents have been developed and are currently being explored for the treatment of breast cancer patients, including those diagnosed with early-stage disease. Among these agents, neratinib, an oral tyrosine kinase inhibitor that irreversibly inhibits HER1, HER2, and HER4 at the intracellular level, has shown promising results, including when administered to patients previously exposed to trastuzumab-based treatment. This article aims to review the available data on the role of the HER2 pathway in breast cancer and on the different targeted agents that have been studied or are currently under development for the treatment of patients with early-stage HER2-positive disease with a particular focus on neratinib.

    Validation of early detection cancer biomarkers has proven to be disappointing when initial promising claims have often not been reproducible in diagnostic samples or did not extend to prediagnostic samples. The previously reported lack of rigorous internal validity (systematic differences between compared groups) and external validity (lack of generalizability beyond compared groups) may be effectively addressed by utilizing blood specimens and data collected within well-conducted cohort studies. Cohort studies with prediagnostic specimens (eg, blood specimens collected prior to development of clinical symptoms) and clinical data have recently been used to assess the validity of some early detection biomarkers. With this background, the Division of Cancer Control and Population Sciences (DCCPS) and the Division of Cancer Prevention (DCP) of the National Cancer Institute (NCI) held a joint workshop in August 2013. The goal was to advance early detection cancer research by considering how the infrastructure of cohort studies that already exist or are being developed might be leveraged to include appropriate blood specimens, including prediagnostic specimens, ideally collected at periodic intervals, along with clinical data about symptom status and cancer diagnosis. Three overarching recommendations emerged from the discussions: 1) facilitate sharing of existing specimens and data, 2) encourage collaboration among scientists developing biomarkers and those conducting observational cohort studies or managing healthcare systems with cohorts followed over time, and 3) conduct pilot projects that identify and address key logistic and feasibility issues regarding how appropriate specimens and clinical data might be collected at reasonable effort and cost within existing or future cohorts. © Published by Oxford University Press 2015.

    Radiotherapy is an important component in the treatment of breast cancer. (1) Many women with an early stage of breast cancer are candidates for a breast conservation therapy, which combines both conservative surgery and radiotherapy. (2) According to the data from some series, an estimated 90% of the patients treated with radiotherapy for breast cancer will develop a degree of radiation-induced dermatitis. (3) The severity of the skin reactions during and following the breast irradi
