Evaluation of the voluntary deep inspiration breath-hold reproducibility in left-sided breast radiotherapy.

PURPOSE: Voluntary deep inspiration breath hold (v-DIBH) reduces cardiac dose during left-sided breast irradiation. The purpose of this study is to evaluate the reproducibility and variability of breath-hold level (BHL) using breath-hold curves and lateral kV setup images together. MATERIAL/METHOD: A retrospective analysis of 30 left breast cancer patients treated using the v-DIBH technique in our department is performed. The BHL difference is measured from breath hold curves and lateral (LAT) kilo-Voltage (kV) setup images. The planning CT image and the selected treatment fraction data are collected. If the changes in BHL relate to the displacement of various bones in the kV setup, images are assessed. Furthermore, the maximum heart distance inside the treatment field is compared from LAT MV portal images. RESULTS: The median and mean values of the BHL are nearly identical in different fractions (good reproducibility). However, the mean BHL values between planning and all measured fractions are statistically different; 16.3 vs. 20.8 mm for the planning and measured fractions (p < 0.001), which indicates that the variability of BHL is significantly different. CONCLUSION: While reproducibility testing shows good agreement for inter-fractional breath-hold level, the variability between planning and fractions is relatively poor.

Effect of Transcutaneous Electrical Nerve Stimulation on Postoperative Pain and Patient Satisfaction.

BACKGROUND AND AIMS: This study was conducted to investigate the effect of transcutaneous electrical nerve stimulation on postoperative pain, changes in patients' vital signs, and patient satisfaction after inguinal herniorrhaphy. DESIGN: This study used a randomized controlled design. SETTING: A state hospital in the west of Turkey. PARTICIPANTS/SUBJECTS: The study was conducted on 52 patients who had inguinal herniorrhaphy between January and July 2015. METHODS: Patients were randomly divided into two groups (intervention and control). Intervention group patients received transcutaneous electrical nerve stimulation postoperatively five times for 30 minutes each. Electrodes in control group patients were placed, but the device was not started. At each transcutaneous electrical nerve stimulation session, the patients' vital signs and pain severity were recorded. A satisfaction scale was administered before discharge to assess patient satisfaction with nursing care. RESULTS: Pain scores of patients in the intervention group were lower than those in the control group (p < .05). No differences were found in pre-and post-transcutaneous electrical nerve stimulation in the vital signs. Satisfaction scores were higher in the intervention group than control group (p < .05). CONCLUSIONS: After inguinal herniorrhaphy, transcutaneous electrical nerve stimulation reduced postoperative pain without a negative impact on vital signs and increased patient satisfaction with nursing care.

Multimodality imaging with CT, MR and FDG-PET for radiotherapy target volume delineation in oropharyngeal squamous cell carcinoma.

BACKGROUND: This study aimed to quantify the variation in oropharyngeal squamous cell carcinoma gross tumour volume (GTV) delineation between CT, MR and FDG PET-CT imaging. METHODS: A prospective, single centre, pilot study was undertaken where 11 patients with locally advanced oropharyngeal cancers (2 tonsil, 9 base of tongue primaries) underwent pre-treatment, contrast enhanced, FDG PET-CT and MR imaging, all performed in a radiotherapy treatment mask. CT, MR and CT-MR GTVs were contoured by 5 clinicians (2 radiologists and 3 radiation oncologists). A semi-automated segmentation algorithm was used to contour PET GTVs. Volume and positional analyses were undertaken, accounting for inter-observer variation, using linear mixed effects models and contour comparison metrics respectively. RESULTS: Significant differences in mean GTV volume were found between CT (11.9 cm(3)) and CT-MR (14.1 cm(3)), p < 0.006, CT-MR and PET (9.5 cm(3)), p < 0.0009, and MR (12.7 cm(3)) and PET, p < 0.016. Substantial differences in GTV position were found between all modalities with the exception of CT-MR and MR GTVs. A mean of 64 %, 74 % and 77 % of the PET GTVs were included within the CT, MR and CT-MR GTVs respectively. A mean of 57 % of the MR GTVs were included within the CT GTV; conversely a mean of 63 % of the CT GTVs were included within the MR GTV. CT inter-observer variability was found to be significantly higher in terms of position and/or volume than both MR and CT-MR (p < 0.05). Significant differences in GTV volume were found between GTV volumes delineated by radiologists (9.7 cm(3)) and oncologists (14.6 cm(3)) for all modalities (p = 0.001). CONCLUSIONS: The use of different imaging modalities produced significantly different GTVs, with no single imaging technique encompassing all potential GTV regions. The use of MR reduced inter-observer variability. These data suggest delineation based on multimodality imaging has the potential to improve accuracy of GTV definition.

Comparison of synchronisation and fertility after different modifications of the ovsynch protocol in cyclic dairy cows.

The objectives of this study were to evaluate the effects of (1) double doses of PGF2α administration or (2) an exogenous progesterone (CIDR) applied concurrently with, or (3) the day after, first GnRH of Ovsynch (GnRH-1), on synchronisation and fertility during the Ovsynch protocol. All cows (n = 378) received the Ovsynch protocol (GnRH-7d-PGF2α-56h-GnRH-18h-TAI). The 'OVS' group (n = 105) received only the Ovsynch protocol. The 'OVS-PGF' group (n = 118, GnRH-7d-PGF2α-12h-PGF2α-44h-GnRH-18h-TAI) received an extra dose of PGF2α 12 h later on Day 7. The 'OVS-7CIDR' group (n = 78, GnRH+CIDR-7d-PGF2α-56h-GnRH-18h-TAI) received a CIDR for 7 days between GnRH-1 and PGF2α. In the 'OVS-6CIDR' group (n = 77, GnRH-24h-CIDR-6d-PGF2α-56h-GnRH-18h-TAI), CIDR was applied one day after GnRH-1 and removed 6 days later. When all cows were evaluated, the responses to GnRH-2 were higher (P = 0.005) in cows that responded to GnRH-1 (95.4%) compared to the cows that did not respond (87.6%). The pregnancy rates at 31 and 62 days for each group were 48.6% and 42.9% in the OVS, 54.2% and 52.5% in the OVS-PGF, 52.6% and 48.7% in the OVS-7CIDR, and 55.8% and 49.3% in the OVS-6CIDR groups. Thus, none of the three different treatments has an effect on increasing the out-comes of the Ovsynch protocol in cyclic lactating dairy cows.

Real-world experiences in patients with Ewing sarcoma treated at a specialist centre in Turkey.

Objectives: The present study evaluates the clinical outcomes of children, adolescents and adults with Ewing sarcoma and identifies the prognostic factors. Methods: Included in the study were 222 pediatric and adult patients diagnosed with Ewing sarcoma (EwS) who were followed up between 1992 and 2019, and whose data were analyzed retrospectively. Results: The median age of 131 male and 91 female patients included in the study was 13 (1-64). The median follow-up duration of the survivors was 79 months (range, 11-182 months). The 3-year EFS rate of the 222 patients was 34 % (Confidence Interval (CI) (0.158-0.242 %) and the OS rate was 54 % (CI, 0.289-0.590 %). For the non-metastatic patients, the 3-year EFS rate was 47 % and the OS was 68 %, while for the metastatic patients the 3-year EFS rate was 13 % and the OS was 30 %. Of the patient sample, 81 (36, 5 %) survived, of whom 72 were continuously free of disease while the disease persisted in nine, and three developed a secondary neoplasm (2 of whom subsequently died while one survived disease-free). Of the 129 patients who relapsed with metastases and/or local recurrence, eight survived and are disease-free, nine are alive with uncontrolled disease; five were lost to follow-up and 107 died. Conclusion: The findings of the present study suggest metastatic disease at presentation and positive margins after surgery to be of prognostic significance in EwS. Disruptions in aggressive local treatments may reduce the chances of cure in EwS.

Comparison of transcutaneous electrical stimulation and suprascapular nerve blockage for the treatment of hemiplegic shoulder pain.

BACKGROUND: Hemiplegic shoulder pain (HSP) is a common morbidity of stroke. Different treatment modalities can be used for optimizing the results and limiting the possible side effects. This research compares the effects of two therapies used to reduce the pain and improve the quality of life of the patients with HSP. OBJECTIVE: This study aimed to compare the effects of transcutaneous electrical nerve stimulation (TENS) and suprascapular nerve blockage (SSNB) in patients with HSP. METHODS: In this clinical research, 24 patients with HSP who participated in a conventional rehabilitation program were randomized into TENS or SSNB treatment groups. A 100 mm visual analogue scale was used to assess the severity of pain. Passive range of motion (ROM) of the shoulder was measured. The Modified Ashworth Scale (MAS) was used to evaluate spasticity of the upper extremities, and the Modified Barthel Scale was used to assess activities of daily living (ADL). Quality of life was measured using the Stroke-specific Quality of Life (SS-QoL) questionnaire. RESULTS: The pain scores of the SSNB group decreased more significantly (p< 0.05) than in the TENS group. SS-QoL scores at the 3rd week in both groups were significantly higher than before treatment (p< 0.05). MAS scores and Barthel scores after treatment did not differ significantly between the groups. CONCLUSION: TENS and SSNB were beneficial in relieving pain and increasing passive shoulder ROM and ADL in all patients. The alleviating of pain was faster in patients who underwent SSNB.

The effect of lower urinary tract substructure doses on side effects of cervical cancer image-guided adaptive brachytherapy.

OBJECTIVE: Image-Guided Adaptive Brachytherapy (IGABT) provides a survival advantage in locally advanced cervical cancer (LACC). Although side effects are seen less with this technique, dose parameters that cause urinary side effects are still questionable. We aim to investigate whether the radiotherapy doses of the lower urinary tract substructures (LUSS) affect the urinary system side effects (USSE) of cervical cancer external beam radiotherapy (EBRT) and the IGABT. METHODS: LUSS (bladder, trigone, bladder neck, and urethra) doses were calculated in 40 patients diagnosed with LACC and receiving primary EBRT, IGABT, and concomitant chemotherapy. D0.1cc, D2cc, and D50% values were examined by contouring the bladder, trigone, bladder neck, and urethra from the intracavitary BT planning computed tomography (CT) images taken every 4 BT fractions, retrospectively. Besides, late USSE (urgency, dysuria (recurrent), frequency, obstruction, incontinence, hematuria, fistula, cystitis) were queried and categorized according to Common Toxicity Criteria for Adverse Events version 5.0. STATISTICAL ANALYSIS USED: The Chi-square and Fisher's exact tests, Mann-Whitney U-test. RESULTS: For the whole study population, for both incontinence and dysuria, trigone (D50%), urethra (D50%, D0.1cc,), and bladder neck (D50%, D0.1cc, D2cc) volume and hot spot doses remained significant. For cystitis, urethra (D50%, D0.1cc,) and bladder neck doses (D0.1cc, D50%, D2cc) are worth investigating. CONCLUSIONS: Although USSE is less common in the intensity-modulated radiation therapy and IGABT era, it may be meaningful to take the doses of LUSS into account when planning IGABT. In addition, delineation of LUSS using only CT seems feasible. More proof is needed to determine delineation technique and dose constraints for LUSS for IGABT.

The validity and reliability of the Turkish version of the University of Washington Quality of Life Questionnaire for patients with head and neck cancer.

PURPOSE: The University of Washington Quality of Life Questionnaire (UW-QOL) is an English-language survey used to assess the quality of life of patients with head and neck cancer. The present study aimed to translate this widely used questionnaire into Turkish according to international guidelines and to statistically determine its validity and reliability by administering it to native Turkish-speaking patients. MATERIALS AND METHODS: This prospective study was performed at Hacettepe University, Faculty of Medicine, Turkey. The study included patients newly diagnosed as having head and neck cancer. Translation and cultural adaptation of the questionnaire were performed first. Then, the translated version was tested on a consecutive series of patients seen in the department of otorhinolaryngology head and neck surgery and the department of radiation oncology between September 2006 and February 2008. The patients were asked to complete 3 sets of questionnaires. The first set was completed 1 day before the beginning of treatment, the second 3 months after the completion of treatment, and the third 10 days after the second questionnaire was completed. The first and second sets included the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire-Turkish version and UW-QOL-Turkish version. The third set included the Turkish UW-QOL only. Performance status was assessed and rated by a physician using the Karnofsky and ZEW (Zubrod/The Eastern Cooperative Oncology Group (ECOG)/World Health Organization) performance scales, synchronous with the first and second sets of questionnaires. RESULTS: The original English version of UW-QOL was carefully translated into Turkish, and a final Turkish version of UW-QOL was developed in an iterative fashion. To determine its validity and reliability, 67 patients were included in the study. Internal consistency (Cronbach α = .757) was adequate, and test-retest reliability (interclass correlation coefficient, 0.941) was excellent. The composite scores of the translated UW-QOL were compared statistically with the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire scores, Karnofsky and ZEW performance scales, T stage of the disease, and UW-QOL global questions scores to support the scale's construct validity, and statistically significant associations were observed. CONCLUSIONS: The Turkish UW-QOL appears to be a valid and reliable tool for use with Turkish patients with head and neck cancer; it can also be used in clinical investigations and routine clinical practice in Turkey.

A Case of Hypopharyngeal Cancer Associated With Fanconi Anemia: A Helical Tomotherapy Experience.

Fanconi anemia (FA) is a disease that could be accompanied by multiple abnormalities, such as growth retardation, bone marrow abnormalities, and cancer susceptibility. Among the FA patients, head and neck squamous cell cancer (HNSCC) is the most observed solid cancer. The life expectancy of patients with FA has increased with recent medical advances. Furthermore, HNSCC is diagnosed in 3% of FA patients, and half of these patients die because of their HNSCC. The median age of HNSCC patients with FA is 31, and according to the literature HNSCC incidence of FA, patients is more than 700-fold of the normal population. Here, we reported the treatment details and challenges we faced during hypopharyngeal cancer treatment in a FA patient.

Lung stereotactic ablative radiotherapy (SABR): dosimetric considerations for chest wall toxicity.

OBJECTIVE: To investigate chest wall pain in patients with peripheral early stage lung cancer treated with stereotactic ablative radiotherapy (SABR), and to identify factors predictive of Common Terminology Criteria of Adverse Events Grade 2 + chest wall pain. METHODS: Patients who received 55 Gy in five fractions were included. A chest wall structure was retrospectively defined on planning scans, and chest wall dosimetry and tumour-related factors recorded. Logistic regression was performed to identify factors predictive of ≥Grade 2 chest wall pain. RESULTS: 182 patients and 187 tumours were included. There were 20 (10.9%) episodes of ≥Grade 2 chest wall pain. Multivariate logistic regression demonstrated that the maximum dose received by 1 cm(3) of chest wall (Dmax1 cm(3)) and tumour size were significant predictors of ≥Grade 2 chest wall pain [Dmax1 cm(3) odds ratio : 1.104, 95% confidence interval : 1.012-1.204, p = 0.025; tumour size (mm) odds ratio : 1.080, 95% confidence interval : 1.026-1.136, p = 0.003]. This model was an adequate fit to the data (Hosmer and Lemeshow test non-significant) and a fair discriminator for chest wall pain (area under receiver-operating characteristic curve: 0.74). Using the multivariate logistic regression model, parameters for Dmax1 cm(3) are provided, which predict <10% and <20% risks of ≥Grade 2 chest wall pain for different tumour sizes. CONCLUSION: Grade 2+ chest wall pain is an uncommon side effect of lung SABR. Larger tumour size and increasing Dmax1 cm(3) are significant predictors of ≥Grade 2 chest wall pain. When planning lung SABR, it is prudent to try to avoid hot volumes in the chest wall, particularly for larger tumours. ADVANCES IN KNOWLEDGE: This article demonstrates that Grade 2 or greater chest wall pain following lung SABR is more common when the tumour is larger in size and the Dmax1 cm(3) of the chest wall is higher. When planning lung SABR, the risk of chest wall pain may be reduced if maximum doses are minimized, particularly for larger tumours.

Whole Brain Radiotherapy Combined with Stereotactic Radiosurgery versus Stereotactic Radiosurgery Alone for Brain Metastases.

BACKGROUND: The aim of this study was to evaluate the effect of whole brain radiotherapy (WBRT) combined with streotactic radiosurgery versus stereotactic radiosurgery (SRS) alone for patients with brain metastases. MATERIALS AND METHODS: This was a retrospective study that evaluated the results of 46 patients treated for brain metastases at Dr. Abdurrahman Yurtaslan Ankara Oncology Training and Research Hospital, Radiation Oncology Department, between January 2012 and January 2015. Twenty-four patients were treated with WBRT+SRS while 22 patients were treated with only SRS. RESULTS: Time to local recurrence was 9.7 months in the WBRT+SRS arm and 8.3 months in SRS arm, the difference not being statistically significant (p= 0.7). Local recurrence rate was higher in the SRS alone arm but again without significance (p=0,06). CONCLUSIONS: In selected patient group with limited number (one to four) of brain metastases SRS alone can be considered as a treatment option and WBRT may be omitted in the initial treatment.

The Prognostic Role of the Neutrophil-to-Lymphocyte Ratio in Oropharyngeal Carcinoma Treated with Chemoradiotherapy.

BACKGROUND: The aim of the study is to investigate the prognostic role of pre-treatment of markers of the systemic inflammatory response (neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and albumin) in patients with oropharyngeal carcinoma treated with chemoradiotherapy. METHODS: A total of 251 patients with oropharyngeal squamous cell cancer treated with chemoradiotherapy between 2004 and 2010 were retrospectively identified. NLR, PLR, and albumin were recorded from baseline blood parameters. NLR threshold of >5 and PLR thresholds of ≤150, >150 and ≤300, and >300 were used for analysis. RESULTS: Median follow-up was 46 months (range 9-98). The 3 year overall survival, local control, regional control, and distant control were 70%, 85%, 87%, and 87%, respectively. On multivariate analysis, locoregional control was associated with T stage (HR 3.3 (95% CI 1.5-6.9), P = 0.002) and NLR (HR 2.1 (95% CI 1.1-3.9), P = 0.023). Overall survival was associated with T stage (HR 2.47 (95% CI 1.45-4.2), P = 0.001) and grade (HR 0.61 (95% CI 0.38-0.99), P = 0.048). PLR and albumin were not significantly associated with disease outcomes or survival. CONCLUSIONS: The NLR is an independent prognostic factor for locoregional control in oropharyngeal cancer treated with chemoradiotherapy.

Scrotal skin metastasis from rectum adenocarcinoma.

Cutaneous metastases of rectal adenocarcinoma is a rare phenomenon. We present a 65 year-old man with a painless nodule on the scrotal skin. Excisional biopsy of the nodules revealed a metastasis from rectum adenocarcinoma. Afterwards, the left scrotum was treated with a radiation therapy and the patient also received a salvage chemotherapy. The patient is still alive without any distant metastasis after the therapy, which was initiated 12 months ago.

Optic nerve glioma treatment with fractionated stereotactic radiotherapy.

In the current report, the authors present a case of optic nerve glioma treated with fractionated stereotactic radiotherapy (FSRT). An 11-year-old girl was referred to our clinic with increasing proptosis over a 1-year period. At that time orbital MRI revealed a 20 × 17-mm mass in the right retroorbital lipomatous tissue, and FSRT was delivered to the tumor using the CyberKnife. During the 1.5-year follow-up, ophthalmological examinations did not indicate any treatment-related severe toxicity, and posttreatment MRI demonstrated marked regression of the lesion to 13 × 10 mm. Given the scarcity of reports on this subject, the authors support more extended studies of the CyberKnife for the effective treatment of this relatively common childhood tumor.

Outcomes following chemoradiotherapy for N3 head and neck squamous cell carcinoma without a planned neck dissection.

OBJECTIVES: The optimal management of the N3 neck in head and neck squamous cell carcinoma (HNSCC) remains controversial. We report the outcomes of patients with N3 disease treated with a strategy of concurrent chemo-radiotherapy (CRT)±induction chemotherapy (ICT) without a planned neck dissection. MATERIALS AND METHODS: Forty patients with HNSCC N3 disease treated between January 2004 and December 2010 were retrospectively identified. Inclusion criteria for the study were: non-nasopharyngeal HNSCC, N3 nodal disease, intention to treat with CRT±ICT. RESULTS: Median age was 60 (range 39-74). Median follow up was 32 months (range 8-88). 34 (85%) of patients received ICT. 35 patients received cisplatin-CRT, 4 carboplatin-CRT and 1 patient was treated with radiotherapy alone due to ICT toxicity. 27 (67.5%) patients had a complete response (CR) to CRT. 5 (12.5%) patients had an incomplete response in both the primary and nodal sites. 8 (20%) patients had a CR in the primary site but incomplete in the nodal regions. The crude rate of regional failure following a CR was 3/27 (11.2%). Isolated regional failure occurred in 1/27 (3.7%) patients who had achieved a CR post-CRT. 3 year overall survival, disease free survival, locoregional control, local control and regional control in the whole cohort were 51.4%, 49.6%, 65.7%, 77.3%, 69.3%, and in patients with a CR were 73.3%, 70.0%, 86.6%, 90.5% and 91.7% respectively. CONCLUSION: Isolated regional nodal failure is rare following a complete response to CRT for N3 HNSCC managed without a planned neck dissection.
