Health-related quality of life of young women with breast cancer. Review of the literature.

PURPOSE: The purpose of the present article was to investigate the health related quality of life (QoL) of young women with breast cancer. METHODS: For the purposes of this article, we reviewed the literature via the electronic databases Pubmed, Scopus and Google Scholar. Key words used were breast cancer, young women, health related quality of life, and quality of life. RESULTS: Young women reported fatigue, pain in the breast and hand problems with lymphedema as the most frequent physical effects of treatment. Other physical problems were the not periodic and painful menses, vaginal dryness and loss of libido. Many young women had depressive symptoms such as depressed mood, helplessness, hopelessness, sleep loss, psychomotor retardation and disorders of appetite. There were often concerns about the health monitoring and self-image, while they were anxious if they will have a baby in the future or if they can nurture the existing ones. Many problems arose in the career of young women. They faced discrimination in the labor supply and/or layoff because they were considered unable to do their job effectively. In addition, they reported isolation problems and feeling different from other women of similar age. CONCLUSIONS: Young women consider that their healthrelated QoL is worse compared with older women. Young women worry about their future, with particular reference to their role as mothers and especially to children-bearing. The free screening and non-exclusion of young women is particularly important for breast cancer prevention and women's well-being.

A five split-field three dimensional conformal technique versus an anterior-posterior on in postoperative radiotherapy for gastric carcinoma: a multicenter comparative study using quality of life measurements as well as clinical and dosimetric parameters.

PURPOSE: Several adjuvant approaches are regarded as available options in the management of localized, resectable gastric cancer .The objective of our study was to evaluate multiple field and anteroposterior conformal technique. METHODS: Ninety-seven patients received three dimensional conformal (3DCRT) postoperative adjuvant radiation therapy for gastric carcinoma. Thirty-five patients received anteroposterior (AP/PA) fields (Group B), while 62 patients were irradiated with multifield technique (Group A). Their ages ranged between 29-85 years. The objective of the study was to evaluate the quality of life (QoL) for all patients after the completion of radiotherapy using the QLQ-C30 of the EORTC questionnaire (European Organization for Research and Treatment of Cancer) and to investigate any measurable differences between those two radiation techniques according to QUANTEC criteria and the radiotoxicity. RESULTS: In terms of QUANTEC criteria, the multifield technique was superior concerning the left kidney (p=0.025), right kidney (p<0.001), spinal cord (p<0.001) and planning target volume (PTV) coverage (p<0.001). According to EORTC/ RTOG toxicity criteria, the rate of diarrhea was higher in AP/ PA technique (p=0.028). In terms of QLQ-C30, the multifield technique was superior concerning appetite loss (p=0.022), diarrhea (p=0.046) and global QoL (p<0.001). CONCLUSION: On the basis of QLQ-C30 questionnaire, EORTC/ RTOG toxicity and dosimetric parameters, the present report has shown that the three dimensional multifield conformal radiotherapy is superior compared to AP-PA techniques.

Utilizing Yoga in Oncologic Patients Treated with Radiotherapy: Review.

PURPOSE: Several trials on noncancer population indicate that yoga is associated with meaningful clinical effects. This study evaluated the physical and psychosocial outcomes of yoga in oncologic patients treated with radiotherapy. METHODS: We focused on a research through Cochrane Register of Controlled Trials (CENTRAL), BioMed Central, and MEDLINE studies up to May 2017. RESULTS: Yoga was found to have a substantial benefit in cancer patients' distress, anxiety, and depression. It also demonstrated a moderate impact on fatigue and emotional function and a small and insignificant effect on functional well-being and sleep disturbances. As far as the effects on psychological outcomes are concerned, there was insufficient evidence. CONCLUSIONS: This systematic review of randomized controlled trials showed that yoga has strong beneficial effects on oncologic patients' quality of life. Results of the current review must be interpreted with caution due to the relative small sample sizes of most of the included studies, while a prospective randomized study stands in need for the confirmation of our results.

Validity and reliability of the Greek version of the xerostomia questionnaire in head and neck cancer patients.

PURPOSE: Xerostomia after radiation therapy for head and neck (H&N) cancer has serious effects on patients' quality of life. The purpose of this study was to validate the Greek version of the self-reported eight-item xerostomia questionnaire (XQ) in patients treated with radiotherapy for H&N cancer. METHODS: The XQ was translated into Greek and administered to 100 XQ patients. An exploratory factor analysis was performed. Reliability measures were calculated. Several types of validity were evaluated. The observer-rated scoring system was also used. RESULTS: The mean XQ value was 41.92 (SD 22.71). Factor analysis revealed the unidimensional nature of the questionnaire. High reliability measures (ICC, Cronbach's α, Pearson coefficients) were obtained. Patients differed statistically significantly in terms of XQ score, depending on the RTOG/EORTC classification. CONCLUSION: The Greek version of XQ is valid and reliable. Its score is well related to observer's findings and it can be used to evaluate the impact of radiation therapy on the subjective feeling of xerostomia.

How can we effectively address the paraneoplastic dermatomyositis: Diagnosis, risk factors and treatment options.

PURPOSE: Dermatomyositis (DM) represents an auto-immune inflammatory myopathy. In this review, we analyzed the incidence of DM as a clinical manifestation highlighting the peculiar clinical and treatment characteristics of this disease when occurring in the context of different malignancies. METHODS: A systematic literature review was performed based on database search in PubMed/Medline and included English articles until December 2016. RESULTS: In up to 20% of cases DM appears as a paraneoplastic syndrome associated with multiple malignancies such as ovarian, breast, prostate, lung, nasopharyngeal and colorectal cancer, and non-Hodgkin lymphomas. It can be presented either before, in the time, or after cancer diagnosis. Systemic sclerosis and mixed connective-tissue disease represent common coinciding disorders. Particular caution should be given in the radiotherapy because the microvascular endothelial radiation damage and autoimmune inflammatory collagen vascular disease caused by DM may be additive. There is a higher risk of late toxicity in the presence of other concurrent vascular diseases, including diabetes, hypertension or administration of chemotherapy. Prednisone represents the first-line treatment option but immunosuppressive drugs such as azathioprine and methotrexate may also be incorporated in the therapeutic armamentarium especially when DM is associated with malignancy. Intravenous immunoglobulin could be a promising alternative in prednisone-resistant cases. The effectiveness of therapies with antigen-specific agents such as monoclonal antibodies is currently under investigation. CONCLUSIONS: Timely diagnosis coupled with a treatment plan focused on muscular endurance and improvement of skin lesions and other symptoms offer a favorable response to therapy along with the achievement of a higher quality of life for these patients.

Addressing the post-irradiation hypothalamic-pituitary endocrine abnormalities of brain tumors in pediatric patients.

PURPOSE: Hypothalamic-pituitary axis is susceptible to radiotherapy, causing endocrine disorders to childhood cancer survivors. We conducted a systematic review in order to assess the radiation-induced toxicity that leads to hormone secretion abnormalities and their severity in children with brain tumors. METHODS: The data were collected by relevant studies on PubMed and EMBASE. Articles up to December 2016 were included. We selected studies which focused on children patients (<18 yr old) with brain tumors treated with radiotherapy and the consequences for their endocrine system. RESULTS: Growth hormone (GH) deficiency was the most common post-irradiation abnormality among children cancer survivors, followed by gonadotrophin (GT), thyroid stimulating hormone (TSH), corticotropin (ACTH) and prolactin (PRL) disorders. CONCLUSIONS: The age of the patient, total radiotherapy dose, number of fractions, fraction size and the duration of treatment seem to determine the severity of these disturbances.

Stage-II thymoma and emergency coronary artery bypass. To irradiate or not to irradiate to avoid radiation induced vascular injury? Case report and literature review.

PURPOSE: The purpose of this study was to present the controversial role of adjuvant radiotherapy to a 72-year-old male patient with Masaoka stage II thymoma and coronary artery bypass and to review the relevant literature. METHODS: The data were collected by relevant studies on PubMed and EMBASE. Articles up to March 2017 were included. RESULTS: Although the radiation-induced vascular injury to the internal thoracic artery and its suitability for grafting in a patient who is candidate for coronary artery bypass is documented, the possible catastrophic effect of adjuvant radiotherapy to existing grafts in a patient with prior bypass surgery has not been fully investigated. CONCLUSION: The application of radiotherapy in a patient with R0 stage II thymoma is currently considered of 2B level of evidence but its potential occlusive effect to an underlying coronary graft may dramatically affect the survival of the patient and accordingly drop the level of evidence of its use.

Carcinoembryonic antigen and carbohydrate antigen 19-9 serum levels in non-small cell lung cancer.

PURPOSE: Τo investigate the potential diagnostic and prognostic role of carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA 19-9) serum levels in non-small cell lung cancer (NSCLC). METHODS: One hundred consecutive patients with newly diagnosed primary NSCLC were included in this study (88 men and 12 women). Blood was drawn before any kind of treatment and the collected serum was processed using chemiluminescence in order CEA and CA 19-9 levels to be measured. RESULTS: No significant associations between CEA or CA 19-9 levels and any tested clinical and pathological parameter were detected. Moreover, CEA levels did not seem to affect survival. On the other hand, patients with high CA 19-9 values (≥37 IU/ml) (median survival: 8 months) had a shorter overall survival than patients with low CA 19-9 values (<37 IU/ml) (median survival: 13 months) (p=0.026). However, CA 19-9 levels did not remain an independent prognostic factor in the multivariate survival analysis (p=0.114). CONCLUSION: CEA and CA 19-9 serum levels do not seem to have any diagnostic role in NSCLC. With regard to their prognostic role, CEA values do not seem to affect the prognosis in NSCLC. However, high CA 19-9 values are associated with worse prognosis.

Primary extramammary invasive Paget's vulvar disease: what is the standard, what are the challenges and what is the future for radiotherapy?

BACKGROUND: Primary invasive Extramammary Paget's vulvar disease is a rare tumor that is challenging to control. Wide surgical excision represents the standard treatment approach for Primary invasive Extramammary Paget's vulvar disease. The goal of the current study was to analyze the appropriate indications of radiotherapy in Primary invasive Extramammary Paget's vulvar disease because they are still controversial. DISCUSSION: We searched the Cochrane Gynecological Cancer Group Trials Register, Cochrane Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE database up to September 2015. Radiotherapy was delivered as a treatment in various settings: i) Radical in 28 cases (range: 60-63 Gy), ii) Adjuvant in 25 cases (range: 39-60 Gy), iii) Salvage in recurrence of 3 patients (63 Gy) and iv) Neoadjuvant in one patient (43.3 Gy). A radiotherapy field that covered the gross tumor site with a 2-5 cm margin for the microscopic disease has been used. Radiotherapy of the inguinal, pelvic or para-aortic lymph node should be considered only for the cases with lymph node metastases within these areas. Radiotherapy alone is an alternative therapeutic approach for patients with extensive inoperable disease or medical contraindications. Definitive radiotherapy can be used in elderly patients and/or with medical contraindications. Adjuvant radiotherapy may be considered in presence of risk factors associated with local recurrence as dermal invasion, lymph node metastasis, close or positive surgical margins, perineal, large tumor diameter, multifocal lesions, extensive disease, coexisting histology of adenocarcinoma or vulvar carcinoma, high Ki-67 expression, adnexal involvement and probably in overexpression of HER-2/neu. Salvage radiotherapy can be given in inoperable loco-regional recurrence and to those who refused additional surgery.

Splenic irradiation as palliative treatment for symptomatic splenomegaly due to secondary myelofibrosis: a multi-institutional experience.

PURPOSE: To evaluate the impact of splenic irradiation as a palliative treatment for symptomatic splenomegaly due to secondary myelofibrosis. METHODS: Seventeen patients with chronic myelogenous leukemia and 3 with idiopathic polycythaemia presented with splenomegaly, splenic pain and anemia. Due to symptomatic splenomegaly, despite first-line treatment, the patients underwent splenic irradiation. Two patients received two different schedules of external radiotherapy (580 cGy in 5 fractions and 600 cGy in 6 fractions). Eight patients received 980 cGy in 14 fractions. Ten patients received two courses of 360 cGy in 6 fractions, 3 months apart. Median follow-up was 12 months post irradiation. RESULTS: The patients showed excellent response to treatment one month post-radiotherapy, while treatment was well tolerated without severe toxicity. The dimensions of the spleen decreased significantly. Pain-related Visual Analogue Score (VAS) regressed after completion of irradiation. During 12-month follow-up all patients maintained the benefit of radiotherapy. CONCLUSION: This study indicates that splenic irradiation could be a safe and effective palliative treatment for symptomatic splenomegaly due to secondary myelofibrosis.

The impact of intermediate time between chemotherapy and hypofractionated radiotherapy to the radiation induced skin toxicity for breast adjuvant treatment.

To evaluate the impact of intermediate time between chemotherapy and radiotherapy (ITCR) to skin toxicity for a hypofractionated irradiation schedule. Forty-four patients with stage I-II invasive breast cancer receiving postoperative radiotherapy (RT) after lumpectomy and axillary dissection were studied. All patients received RT with 6 MV linear accelerator (LINAC) with a total tumor dose of 53 Gy (Equivalent dose-EQD2- 60 Gy), 2.65 Gy per fraction, in 20 fractions. All patients received six cycles of cyclophosphamide methotrexate fluorouracil chemotherapy i.v. every 21 days. Acute and late effects and cosmetic results were assessed using the European Organization for Research and Treatment of Cancer and Radiation Therapy Oncology Group (EORTC/RTOG) Rating System. The mean follow-up was 7 years. The spearman rho test showed that there was a significant correlation between short ITCR and acute skin toxicity 3 months post RT, by means of acute radiation induced morbidity. None of the related late-toxicity parameters was correlated with the ITCR. However, there was significantly higher acute toxicity when the ITCR was less than 20 days (p < 0.05). We may suggest that when a hypofractionated irradiation schedule is used for breast cancer patients, then the ITCR should be more than 20 days from chemotherapy.

Otto Hahn (1879-1968): pioneer in radiochemistry and discoverer of radiotherapeutic mesothorium.

Otto Hahn was a German innovative chemist. He had discovered various radioactive elements, as well as the nuclear fission. He finally received the Nobel Prize for his participation in the atomic energy project, which Hahn and others considered that could be a factor used for peaceful means like cheap electricity and cheap industrial products. His greatest discovery though in oncology was mesothorium, a radioactive element that had been used to treat all cancer types at the beginning of the 20th century.

Does adaptive radiotherapy for head and neck cancer favorably impact dosimetric, clinical, and toxicity outcomes?: A review.

PURPOSE: The current review aims to summarize the international experience of the impact of adaptive radiotherapy on dosimetry and clinical and toxicity outcomes. Additionally, it might trigger Radiation Oncologists to use ART and evaluate whether ART improves target volume coverage and/or normal tissue sparing and, consequently, therapeutic results. MATERIALS AND METHODS: We conducted an electronic literature search of PubMed/MEDLINE and ScienceDirect from January 2007 to January 2023. The search adhered to the PRISMA guidelines and employed keywords such as ART, HNC, parotid gland, and target volume. Furthermore, we examined the reference lists for studies pertinent to the present review. This study included both retrospective and prospective studies that were considered for inclusion. CONCLUSION: ART replanning appears to be a sustainable strategy to minimize toxicity by improving normal tissue sparing. Furthermore, it can enhance target volume coverage by correctly determining the specific dose to be delivered to the tumor. In conclusion, this review confirmed that ART benefits dosimetric, clinical/therapeutic, and toxicity outcomes.

A new role of PET/CT for target delineation for radiotherapy treatment planning for head and neck carcinomas.

Fluorine-18-fluorodeoxyglucose- positron emission tomography ((18)F-FDG PET) in head and neck cancer patients is useful for staging, identification of macroscopic disease, detection of invaded lymph nodes and distant metastases, delineation of radiotherapy target volume and assessment of treatment response. This brief review addresses the potential role of PET in radiotherapy planning as compared to MRI and CT scan. Positron emission tomography is considered by radiation oncologists a useful test for the identification of the specific target volume for treatment. In addition, a number of hypoxia-related PET radiopharmaceuticals such as the fluorine-18-fluoromisonidazole ((18)F-FMISO) and the fluorine-18-fluoroazomycin arabinoside ((18)F-FAZA) are now available in order to identify hypoxic tumor subvolumes helping to implement new radiotherapy techniques. Magnetic resonance imaging (MRI) has the advantage to discriminate the soft tissue contrast from the tumor, against computerized tomography (CT), but PET/CT scans have the additional advantage to incorporate the metabolic imaging for improving the delineation of variable and hypoxic tumor tissue in the head and neck region. Regardless of the method used for determining the gross tumor volume, clinical examination remains irreplaceable. In conclusion, PET/CT offers complementary information for the delineation of the primary tumor and the corresponding lymph nodes compared to the use of MRI and CT and can support the use of modern radiotherapy techniques, having fewer toxicities.

Vaginal dilator use to promote sexual wellbeing after radiotherapy in gynecological cancer survivors.

ABSTRACT: This study investigated the efficacy of a vaginal dilator (VD) for the treatment of radiation-induced vaginal stenosis (VS) and the effect of a VD on sexual quality of life.Fifty three patients with endometrial or cervical cancers participated in this prospective observational study. All participants were treated with radical or adjuvant external beam radiotherapy and/or brachytherapy. They were routinely examined 4 times after radiotherapy (RT) and were also asked to complete a validated sexual function-vaginal changes questionnaire. SPSS version 20 and Minitab version 16 were used for the statistical analysis. The statistical significance was set at P < .05.The VS grading score decreased and the comfortably insertable VD size gradually increased throughout a year of VD use; all patients with initial grade 3 showed a VS of grade 2 after 12 months of VD use and 65.8% of the patients with initial grade 2 demonstrated a final VS of grade 1, while 77.8% of the participants who started with the first size of VD reached the third size after 12 months. Starting VD therapy ≤3 months after the end of RT was associated with a significant decrease in VS. A total of 60.9% of participants reported that they did not feel their vaginas were too small during intercourse after 12 months of dilation, whereas only 11.5% gave the same answer before starting dilation. Furthermore, 47.17% rated their satisfaction with their sexual life 5 out of 7 and only 3.77% gave a score of 3 after 12 months of dilation.Endometrial and cervical cancer survivors are encouraged to use VD to treat VS and for sexual rehabilitation after RT. This study recommends starting vaginal dilation no more than 3 months after treatment at least 2 to 3 times a week for 10 to 15 minutes over 12 months. However, larger, well-designed randomized clinical trials should be conducted to develop specific guidelines for VD use and efficacy in VS and sexual sexual quality of life after RT.

Is Locally Advanced Head-Neck Cancer One More Candidate for Accelerated Hypofractionation?

BACKGROUND/AIM: Hypofractionated accelerated radiotherapy (HypoAR) is widely applied for the treatment of early laryngeal cancer. Its role in locally advanced head-neck cancer (LA-HNC) is unexplored. PATIENTS AND METHODS: We present results of a prospective trial on 124 patients with LA-HNC, treated with radio-chemotherapy with three different HypoAR fractionations (3.5 Gy/day × 14-15 fractions, 2.7 Gy/day × 20-21 fractions, and 2.5 Gy/day × 21-22 fractions). RESULTS: Protraction of the overall treatment time due to oropharyngeal mucositis was enforced in 18/57 laryngeal, 6/19 nasopharyngeal, and 15/48 cancer patients with other tumors. Regarding late toxicities, laryngeal edema grade 3 was noted in 5/57 patients with laryngeal cancer, while severe dysphagia was noted in 4/124 and tracheoesophageal fistula formation in 1/124 patients. The complete response rates obtained were 73%, 84%, and 67% in patients with laryngeal, nasopharyngeal, and other tumors, respectively. The 3-year locoregional progression-free survival was 58%, 73%, and 55%, respectively. CONCLUSION: HypoAR chemoradiotherapy is feasible, with acceptable early and late radiotherapy toxicities, response rates and LPFS.

Modern radiopharmaceuticals for lung cancer imaging with positron emission tomography/computed tomography scan: A systematic review.

INTRODUCTION: In this study, we evaluated the use and the contribution of radiopharmaceuticals to the field of lung neoplasms imaging using positron emission tomography/computed tomography. METHODS: We conducted review of the current literature at PubMed/MEDLINE until February 2020. The search language was English. RESULTS: The most widely used radiopharmaceuticals are the following:Experimental/pre-clinical approaches: (18)F-Misonidazole (18F-MISO) under clinical development, D(18)F-Fluoro-Methyl-Tyrosine (18F-FMT), 18F-FAMT (L-[3-18F] (18)F-Fluorothymidine (18F-FLT)), (18)F-Fluoro-Azomycin-Arabinoside (18F-FAZA), (68)Ga-Neomannosylated-Human-Serum-Albumin (68Ga-MSA) (23), (68)Ga-Tetraazacyclododecane (68Ga-DOTA) (as theranostic agent), (11)C-Methionine (11C-MET), 18F-FPDOPA, ανß3 integrin, 68Ga-RGD2, 64Cu-DOTA-RGD, 18F-Alfatide, Folate Radio tracers, and immuno-positron emission tomography radiopharmaceutical agents.Clinically approved procedures/radiopharmaceuticals agents: (18)F-Fluoro-Deoxy-Glucose (18F-FDG), (18)F-sodium fluoride (18F-NaF) (bone metastases), and (68)Ga-Tetraazacyclododecane (68Ga-DOTA). The quantitative determination and the change in radiopharmaceutical uptake parameters such as standard uptake value, metabolic tumor volume, total lesion glycolysis, FAZA tumor to muscle ratio, standard uptake value tumor to liver ratio, standard uptake value tumor to spleen ratio, standard uptake value maximum ratio, and the degree of hypoxia have prognostic and predictive (concerning the therapeutic outcome) value. They have been associated with the assessment of overall survival and disease free survival. With the positron emission tomography/computed tomography radiopharmaceuticals, the sensitivity and the specificity of the method have increased. CONCLUSION: In terms of lung cancer, positron emission tomography/computed tomography may have clinical application and utility (a) in personalizing treatment, (b) as a biomarker for the estimation of overall survival, disease free survival, and (c) apply a cost-effective patient approach because it reveals focuses of the disease, which are not found with the other imaging methods.

Acute Leriche Syndrome in Pancreatic Adenocarcinoma: A Case Report.

INTRODUCTION: Coexistance of pancreatic carcinoma and Leriche syndrome is an extremely rare pathological condition. Leriche syndrome is defined as occlusion of the distal aorta at the bifurcation into the common iliac arteries. CASE REPORT: We report the case of a 57-year old male patient with a locally advanced pancreatic tumor that during chemotherapy presented Leriche syndrome. Four months after the diagnosis and although the initial staging by MRI had only revealed a few atheromatic lesions of the abdominal aorta, the patient complained about claudication of the legs and hypoesthesia. Angiography with multi-detector computed tomography (MDCTA) was performed using aortography protocol and three-dimensional reconstruction of the images followed, demonstrating the relationship between pancreatic carcinoma and Leriche syndrome. CONCLUSION: Review of the literature revealed that acute abdominal thrombosis is rare in cancer patients. To our knowledge, complete occlusion of the aorta in a patient with pancreatic cancer has not been reported yet.

Differential Diagnosis of Behavioral Variant and Semantic Variant of Frontotemporal Dementia Using Visual Rating Scales.

BACKGROUND: Frontotemporal dementia (FTD) represents the second most frequent early onset of dementia in people younger than 65 years. The main syndromes encompassed by the term FTD are behavioral variant of Frontotemporal dementia (bvFTD), non-fluent variant primary progressive aphasia (nfvPPA) and semantic variant (SD). AIMS: To assess the bvFTD and SD, which represent the most common subtypes of FTD, using visual rating scales. METHODS: Brain MRI exams of 77 patients either with bvFTD (n=43) or SD (n=34) were evaluated. The rating scales used were: Global cortical atrophy (GCA), Fazekas Scale: periventricular (PV) and white matter (WM) changes, Koedam rating scale and visual scales regarding specific cortical regions: dorsofrontal (DF), orbitofrontal (OF), anterior cingulate (AC), basal ganglia (BG), anterior- temporal (AT), insula, lateral-temporal (LT), entorhinal (ERC), perirhinal (PRC), anterior fusiform( AF), anterior hippocampus (AHIP) and posterior hippocampus (PHIP). Both Left (L) and Right (R) hemispheres were evaluated. RESULTS: R-OF (p=0.059), L-OF (p<0.0005), L-AT (p=0.047) and L-AHIP (p=0.007) have a statistically significant effect on the variable occurrence of SD compared to bvFTD. The indicators with the highest value of the area under the curve (AUC) were R-AC (0.829), L-OF (0.808), L-AC (0.791) and L-AF (0.778). Highest sensitivity was achieved by R-OF (97%) and L-AF (75%). Highest specificity was achieved by L-OF (95%), L-AT (91%) followed by R-AC (84%). Best combination of sensitivity and specificity was achieved by L-AF (74%-79%), L-OF (56%-95%) and R-OF (97%-42%). Best combination of PPV and NPV was achieved by L-OF (90%-73%), LAT (83%-72%) and R-AC (77%-77%). CONCLUSION: Visual rating scales can be a practical diagnostic tool in the characterization of patterns of atrophy in FTLD and may be used as an alternative to highly technical methods of quantification.

Evaluation of the Irradiated Volume of the Heart and Cardiac Substructures After Left Breast Radiotherapy.

Backround/Aim: Adjuvant radiotherapy in patients with cancer of the left breast may lead to impaired cardiac function. The aim of our prospective study is to evaluate (i) doses to the irradiated volume of the heart and its substructures and (ii) determine whether their correlation with changes in strain echo measurements contribute to the prediction of subclinical heart morbidity. PATIENTS AND METHODS: Twenty-five patients were enrolled in our study. We retrospectively assessed the radiation doses to the whole heart, left anterior descending artery (LAD) and left ventricle (LV). RESULTS: The mean heart dose (MHD) was 152 cGy (SD=50.56 cGy) and the range was 74-279 cGy. The LAD was the most exposed structure, with a mean dose of 448.91 cGy (SD=490.53 cGy) and range of 120-2,057cGy. Finally, the mean LV dose was 149.12 cGy (SD=69.57) with a range of 63-317 cGy. CONCLUSION: The early results of our study showed low radiation exposure of the whole heart and left ventricle, and higher exposure of the LAD. The data that will emerge from the evaluation of strain echo parameters should show whether these associations might be useful in clinical practice for the prediction of early subclinical cardiac changes.
