Investigating the levels of depression, anxiety, sexual disorders, and other influencing factors in breast cancer patients: Turkish radiation oncology integrative group study (12-05).

The fear of death associated with cancer and the side effects of its treatments can have a detrimental psychological impact on breast cancer patients. Early detection and support services play a crucial role in alleviating the expected symptoms of depression, anxiety, and sexual dysfunction. The objective of our study is to assess the levels of depression, anxiety, and sexual dysfunction in breast cancer patients, as well as identify the factors that influence these conditions. The study involved 329 voluntarily participating breast cancer patients who had undergone surgery and were in the follow-up stage. Data were collected from 8 different centers after obtaining ethical approval. The assessment utilized tools such as the Sociodemographic Information Form, Beck Depression and Anxiety Scale, and Arizona Sexual Experiences Scale. Data analysis was performed using SPSS 20. The study included 329 breast cancer patients in the follow-up stage post-surgery. Their average age was 52.7 years (range: 27-83). Results indicated that 33.1% experienced moderate to severe depression, 18.2% reported severe anxiety, and 82.7% scored above 11 on the sexual scale. Factors linked to higher scores were mastectomy, surgical dissatisfaction, insufficient information on sexual side effects, and comorbidities like smoking and diabetes. The study emphasizes the importance of closely monitoring anxiety, depression levels, and sexual side effects in breast cancer treatment. It underscores the need to focus not only on reducing mortality rates but also on supporting patients' psychological and sexual well-being, ultimately improving their overall quality of life.

Dosimetric evaluation of different radiotherapy techniques in mastectomized left-sided breast cancer.

CONTEXT: Inclusion of internal mammary lymph nodes in mastectomized left breast cancer radiotherapy may lead to high dose receiving risk of the heart, lung, and contralateral breast. AIM: The aim of this study is to compare the dosimetric differences of field-in-field (FIF), volumetric-modulated arc therapy (VMAT), seven-field intensity-modulated radiotherapy (7F-IMRT), and helical tomotherapy (HT) planning techniques for mastectomized left breast cancer. MATERIALS AND METHODS: Computed tomography images of ten patients treated with the FIF technique were used to compare four different treatment planning techniques. Planning target volume (PTV) included chest wall and regional lymph nodes. The heart, left anterior descending coronary artery (LAD), left and whole lung, thyroid, esophagus, and contralateral breast were identified as organs-at-risks (OARs). Except for HT, a single isocenter in PTV and bolus of thickness 0.3 cm on the chest wall was used. Complete and directional blocks were applied in HT, and the dosimetric parameters of PTV and OARs for four different techniques were analyzed using the Kruskal-Wallis test. RESULTS: 7F-IMRT, VMAT, and HT were superior to the FIF technique in providing homogeneous dose distribution covering the PTV (P < 0.0001). Mean doses (Dmean) of the contralateral breast and esophagus, lung, and body-PTV V5 (volume receiving 5 Gy) were reduced in FIF, whereas in the HT, Heart Dmean, LAD Dmean , Dmax, healthy tissue (body-PTV) Dmean , heart and left lung V20, and thyroid V30 were significantly reduced (P < 0.0001). CONCLUSIONS: FIF and HT techniques were found to be significantly advantageous over 7F-IMRT and VMAT for OARs. Using those three multiple-beam techniques reduced high-dose volumes of healthy tissues and organs in mastectomized left breast cancer radiotherapy but also increased low-dose volumes and contralateral lung and breast doses. Complete and directional blocks applied in HT reduce heart, lung, and contralateral breast doses.

Effects of hyaluronic acid and chondroitin sulfate on acute radiation proctitis in rats.

BACKGROUND: This study was designed to investigate the prophylactic and therapeutic effects of hyaluronic acid and chondroitin sulfate combination (HA/CS) on a model of acute radiation proctitis. METHODS: Rats were divided into five groups: SHAM; irradiation (IR) + saline (1 mL for 5th and 10th day); IR + HA/CS (1 mL for 5th and 10th day). A single fraction of 17.5 Gy was delivered to each rat. HA/CS was administered rectally each day after irradiation. Each rat was observed daily for signs of proctitis. Irradiated rats were euthanized on days 5 and 10. The mucosal changes were evaluated macroscopically and pathologically. RESULTS: According to the clinical findings, five rats in the irradiation + saline group showed grade 3-4 symptoms on the 10th day. No significant difference in the macroscopic finding scores on the 5th day was observed between the irradiation + saline and irradiation + HA/CS groups. In the pathological examination, radiation-induced mucosal damage was the most prominent finding 10 days after irradiation in saline-treated rats. On the 10th day, the irradiation + HA/CS group showed mild inflammation and slight crypt changes, which corresponded to grade 1-2 pathological findings. CONCLUSION: We think that HA/CS used in radiation cystitis can be beneficial for radiation proctitis.

Imaging features of radiation-induced lung disease and its relationship with clinical and dosimetric factors in breast cancer patients.

Aim: The aim is to extensively evaluate imaging features of radiation induced lung disease in breast cancer patients and to determine the relationship of imaging alterations with dosimetric parameters and patient related characteristics. Materials and Methods: A total of 76 breast cancer patients undergoing radiotherapy (RT) were studied retrospectively by case notes, treatment plans, dosimetric parameters, and chest computed tomography (CT) scans. Time intervals, that chest CT scans were acquired, were grouped as 1-6 months, 7-12 months, 13-18 months and more than 18 months after RT. Chest CTs (one or more for each patient) were assessed for the presence of ground glass opacity, septal thickening, consolidation/patchy pulmonary opacity/alveolar infiltrates, subpleural air cyst, air bronchogram, parenchymal bands, traction bronchiectasis, pleural/subpleural thickening and pulmonary volume loss. These alterations were scored by applying a system devised by Nishioka et al. Nishioka scores were analyzed for the relationship with clinical and dosimetric factors. Statistical Analysis Used: IBM SPSS Statistics for Windows, version 22.0 (IBM Corp., Armonk, N.Y., USA) was used to analyze data. Results: Median follow-up time was 49 months. Advanced age and aromatase inhibitor intake were correlated with higher Nishioka scores for 1-6 months' period. However, both were found nonsignificant in multivariate analysis. Nishioka scores of CT scans acquired more than 12 months after RT were positively correlated with mean lung dose, V5, V20, V30, and V40. Receiver operating characteristic analysis revealed that V5 for ipsilateral lung was the most robust dosimetric parameter predicting chronic lung injury. V5 >41% indicates the development of radiological lung changes. Conclusions: Keeping V5 ≤41% for ipsilateral lung could provide avoiding chronic lung sequelae.

Role of vaginal brachytherapy boost following adjuvant external beam radiotherapy in cervical cancer: Turkish Society for Radiation Oncology Gynecologic Group Study (TROD 04-002).

OBJECTIVE: There are a limited number of studies supporting vaginal brachytherapy boost to external beam radiotherapy in the adjuvant treatment of cervical cancer. The aim of this study was to assess the impact of the addition of vaginal brachytherapy boost to adjuvant external beam radiotherapy on oncological outcomes and toxicity in patients with cervical cancer. METHODS: Patients treated with post-operative external beam radiotherapy ± chemotherapy ± vaginal brachytherapy between January 2001 and January 2019 were retrospectively evaluated. The treatment outcomes and prognostic factors were analyzed in patients treated with external beam radiotherapy with or without vaginal brachytherapy. RESULTS: A total of 480 patients were included in the analysis. The median age was 51 years (range 42-60). At least two intermediate risk factors were observed in 51% of patients, while 49% had at least one high-risk factor. The patients in the external beam radiotherapy + vaginal brachytherapy group had worse prognostic factors than the external beam radiotherapy alone group. With a median follow-up time of 56 months (range 33-90), the 5-year overall survival rate was 82%. There was no difference in 5-year overall survival (87% vs 79%, p=0.11), recurrence-free survival (74% vs 71%, p=0.49), local recurrence-free survival (78% vs 76%, p=0.16), and distant metastasis-free survival (85% vs 76%, p=0.09) rates between treatment groups. There was no benefit of addition of vaginal brachytherapy to external beam radiotherapy in patients with positive surgical margins. In multivariate analysis, stage (overall survival and local recurrence-free survival), tumor histology (recurrence-free survival, local recurrence-free survival and distant metastasis-free survival), parametrial invasion (recurrence-free survival and distant metastasis-free survival), lymphovascular space invasion (recurrence-free survival), and lymph node metastasis (distant metastasis-free survival) were found as negative prognostic factors. CONCLUSION: Adding vaginal brachytherapy boost to external beam radiotherapy did not provide any benefit in local control or survival in patients with cervical cancer.

Paraganglioma of the head and neck region, treated with radiation therapy, a Rare Cancer Network study.

BACKGROUND: Paraganglioma of the head and neck (HNPGL) are rare often benign tumors. Surgery and radiation therapy (RT) are the main treatment choices. We present an analysis of outcome and toxicity after RT from 13 institutions of the Rare Cancer Network. METHODS: Data were collected using a questionnaire concerning patients' characteristics, treatment, and outcome. A total of 81 patients with 82 HNPGL were analyzed. RESULTS: The median follow-up was 48 months (1-456). Sixty-two lesions were treated with conventional RT and 20 lesions with stereotactic RT. Local control (LC) was achieved in 69 out of 77 lesions. Late toxicity occurred in 17 patients. Patients treated with stereotactic RT experienced neither disease progression nor late toxicity. Four patients with a follow-up longer than 20 years experienced disease progression. CONCLUSION: RT for HNPGL offered good local control with acceptable toxicity. Stereotactic RT might offer better results. Long-term follow-up is required.

Adjuvant radiotherapy for uterine carcinosarcoma: A retrospective assessment of treatment outcomes.

OBJECTIVES: The objective of the study is to understand the impact of adjuvant radiotherapy (RT) and prognostic factors for patients diagnosed with uterine carcinosarcoma. MATERIALS AND METHODS: The records of 31 patients receiving adjuvant RT between the dates of September 2003-January 2013 in our clinic were evaluated retrospectively. Surgery was performed in 27 (87%) patients as staging laparotomy, for 4 patients as total abdominal hysterectomy and bilateral salpingo-oophorectomy. Pelvic external beam radiotherapy (EBRT) was 4500-5040 cGy in 25-28 fractions. In addition, 23 patients received brachytherapy following EBRT, 12 patients received adjuvant, and 1 patient received neoadjuvant chemotherapy (CT). RESULTS: The median age was 63 (between 30 and 78). The stage distribution of the patients was as follows: Stage I, 20 (64%); Stage II, 7 (23%), and Stage III, 4 (13%) patients. Five-year locoregional control (LRC) rate was 100%, disease-free survival (DFS) and overall survival (OS) rates were 65.5% and 66.2%, respectively. Stage I or II patients have a tendency for better 5-year OS and DFS rates than Stage III patients (73.1% vs. 42.9% and 72.7% vs. 42.9%; P = 0.065 and 0.051). Regarding lymph node dissection was performed or not, 5-year OS (64.7% vs. 75.0%) was not statistically different between groups (P = 0.77). Five-year OS and DFS rates were 69.2% and 61.5% for patients receiving CT (adjuvant or neoadjuvant) versus 63.7% and 68.8% for patients not receiving CT; P = 0.63 and P = 0.89, respectively. Based on the analysis of peritoneal washings, 5-year OS was 0% for patients with malignant or suspicious cytology whereas 89% for patients with benign cytology (P = 0.000). A negative correlation was observed between mitotic count of sarcomatous component and DFS time (rs = -0.812 and P = 0.05). CONCLUSIONS: Surgery and adjuvant RT seem beneficial for excellent LRC rate. However, survival rates are low due to distant metastases. Thus, there is a great need for better systemic therapies.

Evaluation of unusual and highly aggressive variant of endometrium cancer: nonendometrioid endometrium carcinoma of the uterus.

AIMS: To evaluate the survival and treatment outcomes of patients with nonendometrioid endometrium carcinoma after postoperative radiotherapy. METHODS: The records of 94 patients treated with postoperative radiotherapy (RT) between January 2005 and December 2011 were retrospectively reviewed. Postoperative RT was delivered with a dose of 45-50.4 Gy with 1.8 Gy daily fractions and brachytherapy was added to external RT for 62 patients with a dose of 3 × 6 Gy. Median follow-up time was 35 months (range 6-95 months). RESULTS: Median age was 63 years (range 43-83 years) and lymph node metastasis (LNM) was positive in 15 (16.0%) patients. The stage distribution of the patients was as follows: stage I, 58 (61.7%); stage II, 16 (17.0%); stage III, 18 (19.1%); stage IV, 2 (2.2%). Five-year locoregional control (LRC), disease-free survival (DFS), and overall survival (OS) rates were 92.3%, 68.2%, and 78.6%, respectively. In univariable analysis, it was determined that the factors affecting OS rates were stage (p = 0.003), presence of LNM (p = 0.003), and presence of lymphovascular space invasion (LVSI) (p = 0.007); factors affecting DFS rates were stage (p = 0.019), presence of LVSI (p = 0.002), and having LNM (p = 0.049); and the factor affecting LRC rates was tumor size (>5 cm) (p = 0.011). In subgroup analyses, among all stage I patients, the DFS rates were lower for those with histologic grade 3 tumors and more than ½ myometrial invasion. CONCLUSIONS: Due to its rarity, the prognostic factors and outcomes of nonendometioid endometrium carcinoma are not fully understood. In our analysis, stage, LNM, and presence of LVSI were found to be the most important prognostic factors. In order to tailor the optimal treatment strategy, prospective studies are needed.

Treatment results and prognostic factors of patients with vulvar cancer treated with postoperative or definitive radiotherapy.

PURPOSE: Vulvar cancer is a relatively uncommon type of gynecologic cancer. The aim of this study is to analyze the treatment results and prognostic factors of vulvar cancer. METHODS: Forty-four vulvar cancer patients treated between 2000 and 2011 at the Department of Radiation Oncology, Ege University Faculty of Medicine, were retrospectively reviewed. External radiotherapy (RT) was applied with 6-18 MV linear accelerators with 1.8 Gy daily fractions with a median total dose of 50.4 Gy (45-59.4 Gy) for postoperative cases and 64.8 Gy (range 54-66 Gy) for definitive cases. Statistical analyses were performed with SPSS 13.0. RESULTS: Among 44 patients with a median age of 68 years (range 28-86), 14 (31.8%) were treated with curative and 30 (68.2%) were treated with postoperative RT or radiochemotherapy (RCT). According to International Federation of Gynecology and Obstetrics staging, 11 (25%) had stage IB, 10 (22.7%) had stage II, 6 (13.6%) had stage IIIA, 5 (11.4%) had stage IIIB, and 12 (27.3%) had stage IVA disease. Within a median of 24 months (range 6-135) of follow-up, 11 (27.3%) patients had local recurrence, 8 had regional recurrence, 2 had both local and regional recurrence, and 6 had distant metastases. Five-year locoregional, disease-free, and overall survival rates were 45%, 40%, and 54%, respectively. Older age, poor tumor differentiation, positive surgical margin, and lymphovascular space invasion were found to be important prognostic factors for disease-related outcomes. CONCLUSIONS: Prognosis of vulvar cancer remains poor even with a multidisciplinary approach. Molecular prognostic factors need to be defined for individualized treatment options to achieve better treatment results.

Adverse effects of endocrine therapy in breast cancer: single institute experience.

AIM OF THE STUDY: The main purpose of this study is to assess the known adverse effects of adjuvant endocrine therapy for non-metastatic breast cancer patients and to present our single center experience with light of literature. MATERIAL AND METHODS: The breast cancer patients treated with adjuvant radiotherapy in Medical School of Ege University between January 2007 and December 2009 were evaluated for this trial after obtaining their acceptance. Vital findings, bone mineral densitometry, endometrium thickness measured with trans-vaginal ultrasonography, biochemical results including liver function tests and blood lipid profile (total cholesterol, HDL, LDL, VLDL, triglyceride) were recorded for each controls. Socio-demographic data, financial statuses, medical history, co-morbid diseases were obtained from first controls. Patients were followed without any local recurrence and distant metastases until June 2011. RESULTS: Endometrium thickness was not seen in AI using patients. As compared with tamoxifen group, lack of thickness in AI group was statistically significant (p = 0.000). When compared the values before AI, the number of patients who had osteoporosis was gradually increasing. The decrease was seen in the number of patients with osteopenia. The number of patients with normal lipid profile was gradually increasing up to the second evaluation for tamoxifen group (p = 0.000). On the other hand, the number of patients with hyperlipidemia was increasing for AIs group in follow-up period statistically (p = 0.006). CONCLUSIONS: With the aid of careful patient follow and effective disease management strategies, the negative effect over the QoL can be minimized and also the greatest benefit from endocrine therapy can be obtained.

Quality of life assessment in women with breast cancer: a prospective study including hormonal therapy.

PURPOSE: Evaluating the effect of hormonal treatment on quality of life (QoL) in breast cancer patients by using the Functional Assessment of Cancer Treatment (FACT) questionnaire is the main purpose of this trial. METHODS: Breast cancer patients treated with adjuvant between January 2007 and December 2009 were evaluated. The first survey was done after patients completed their whole adjuvant treatment except for the hormonal therapy and this was as 'basal assessment.' The second survey was done 6 to 12 months after the basal surveys during their routine policlinic controls. The last survey was done within the last 18 to 24 months of the follow-up period. RESULTS: The effect of marital status, number of pregnancies, residence in the village or city, hemoglobin levels, chemotherapy and hormonal therapy for any other reason except for breast cancer on the QoL could not be seen. Endocrine subscale scores were detected to be higher in patients aged >60 years than in younger ones. The other dimension scores were low in the elderly patient group. There was a statistically significant relationship between being >30 years old and improvement in the social well-being score (p=0.028). The functional well-being scores were found to be significantly higher in the patient group that had no comorbid disease (p=0.018). Endocrine subscale scores were statistically worse in patients who had psychiatric disease (p=0.057) but the general QoL data were similar with others. It was shown that all QoL scores for all dimensions had statistically significant changes (p<0.001) in terms of hormonal regimes. CONCLUSION: The diagnosis of breast cancer was found to be an independent factor that affects social well-being and social life in a negative way. We must give attention to complaints including complaints about sexual life and hormonal status in order to ensure compliance of patients with the required hormonal regimens. By the help of future research, we can improve the prognosis of this disease through increased treatment adherence and belief of patients.
