    [Show abstract] [Hide abstract] ABSTRACT: Purpose: A cost-utility analysis was performed to assess the cost-utility of neoadjuvant chemotherapy regimens containing doxorubicin and cyclophosphamide (AC) versus paclitaxel and gemcitabine (PG) for locally advanced breast cancer patients in Iran. Materials and methods: This cross-sectional study in Namazi hospital in Shiraz, in the south of Iran covered 64 breast cancer patients. According to the random numbers, the patients were divided into two groups, 32 receiving AC and 32 PG. Costs were identified and measured from a community perspective. These items included medical and non-medical direct and indirect costs. In this study, a data collection form was used. To assess the utility of the two regimens, the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core30 (EORTC QLQ-C30) was applied. Using a decision tree, we calculated the expected costs and quality adjusted life years (QALYs) for both methods; also, the incremental cost-effectiveness ratio was assessed. Results: The results of the decision tree showed that in the AC arm, the expected cost was 39,170 US$ and the expected QALY was 3.39 and in the PG arm, the expected cost was 43,336 dollars and the expected QALY was 2.64. Sensitivity analysis showed the cost effectiveness of the AC and ICER=-5535 US$. Conclusions: Overall, the results showed that AC to be superior to PG in treatment of patients with breast cancer, being less costly and more effective.

    [Show abstract] [Hide abstract] ABSTRACT: Background: Radiotherapy plays an important role as adjuvant treatment in locally advanced breast cancer and in those patients who have undergone breast-conserving surgery. This study aimed to investigate the prognostic impact of adjuvant radiation on oncologic outcomes in elderly women with breast cancer. Materials and methods: In this retrospective study, we reviewed and analyzed the characteristics, treatment outcome and survival of elderly women (aged ≥ 60 years) with breast cancer who were treated and followed-up between 1993 and 2014. The median follow up for the surviving patients was 38 (range 3-207) months. Results: One hundred and seventy-eight patients with a median age of 74 (range 60-95) years were enrolled in the study. Of the total, 60 patients received postoperative adjuvant radiation (radiation group) and the remaining 118 did not (control group). Patients in the radiation group were significantly younger than those in the control group (P value=0.004). In addition, patients in radiation group had higher node stage (P value<0.001) and disease stage (P=0.003) and tended to have higher tumor grade (P=0.031) and received more frequent (P value <0.001) adjuvant and neoadjuvant chemotherapy compared to those in the control group. There was no statistically significant difference between two groups regarding the local control, disease-free survival and overall survival rates. Conclusions: In this study, we did not find a prognostic impact for adjuvant radiation on oncologic outcomes in elderly women with breast cancer.

    [Show abstract] [Hide abstract] ABSTRACT: Purpose: Despite advances in rectal cancer treatment over the last decade, local control and risk of late side effects due to external beam radiation therapy (EBRT) remain as concerns. The present study aimed to investigate the efficacy and the safety of low-dose-rate endorectal brachytherapy (LDRBT) as a boost to neoadjuvant chemoradiation for use in treating locally advanced distal rectal adenocarcinomas. Methods: This phase-II clinical trial included 34 patients (as the study arm) with newly diagnosed, locally advanced (clinical T3-T4 and/or N1/N2, M0) lower rectal cancer. For comparative analysis, 102 matched patients (as the historical control arm) with rectal cancer were also selected. All the patients were treated with LDRBT (15 Gy in 3 fractions) and concurrent chemoradiation (45-50.4 Gy). Concurrent chemotherapy consisted of oxaliplatin 130 mg/m(2) intravenously on day 1 plus oral capecitabine 825 mg/m(2) twice daily during LDRBT and EBRT. Results: The study results revealed a significant differences between the study arm and the control arm in terms in the pathologic tumor size (2.1 cm vs. 3.6 cm, P = 0.001), the pathologic tumor stage (35% T3-4 vs. 65% T3-4, P = 0.003), and the pathologic complete response (29.4% vs. 11.7%, P < 0.028). Moreover, a significantly higher dose of EBRT (P = 0.041) was found in the control arm, and a longer time to surgery was observed in the study arm (P < 0.001). The higher rate of treatment-related toxicities, such as mild proctitis and anemia, in the study arm was tolerable and easily manageable. Conclusion: A boost of LDRBT can optimize the pathologic complete response, with acceptable toxicities, in patients with distal rectal cancer.

  • [Show abstract] [Hide abstract] ABSTRACT: Background: In intracavitary brachytherapy for gynecological cancers, various techniques are used to locate the anterior rectal wall nearest to the sources but there is no consensus on the best method to do so. This study aimed to compare a technique used routinely in some centers that employs a wire marker to locate the position of the maximum rectal dose point, versus the method recommended by the ICRU Report 38. Materials and Methods: In a preliminary prospective study on 34 intracavitary insertions for patients with cervical or endometrial cancer, treated at our center based on the Manchester system, the dose distributions were obtained from a treatment planning system following the input of scanned orthogonal anteroposterior and lateral radiographs. For each case, an in-house marked wire was inserted in the rectal lumen and the doses were calculated on several points along the wire seen on the radiographs, to obtain the maximum dose. For the same insertions, the ICRU method was also applied by considering the rectal wall hot spot as a point 0.5 cm posterior to the posterior vaginal wall (visualized on the radiographs by vaginal packing material containing contrast medium). Results: Averaged over all insertions, mean rectal wall hot spot dose calculated using the positional information obtained by the wire technique was lower by 28.6% than that given by the ICRU method (P < 0.001). Conclusion: Our initial results add evidence to the suggestion that the wire technique underestimates the rectal wall hot spot dose significantly compared to the ICRU method.

    [Show abstract] [Hide abstract] ABSTRACT: Background: Thymomas are rare epithelial tumors arising from thymus gland. This study aims at investigating the clinical presentation, prognostic factors and treatment outcome of forty five patients with thymoma and thymic carcinoma. Methods: Forty-five patients being histologically diagnosed with thymoma or thymic carcinoma that were treated and followed-up at a tertiary academic hospital during January 1987 and December 2008 were selected for the present study. Twelve patients were solely treated with surgery, 14 with surgery followed by adjuvant radiotherapy, 12 with sequential combined treatment of surgery, radiotherapy and/or chemotherapy and 7 with non-surgical approach including radiotherapy and/or chemotherapy. Tumors were classified based on the new World Health Organization (WHO) histological classification. Results: There were 18 women and 27 men with a median age of 43 years. Twelve patients (26.7%) had stage I, 7 (17.8%) had stage II, 23 (51%) had stage III and 2 (4.5%) had stage IV disease. Tumors types were categorized as type A (n=4), type AB (n=10), type B1 (n=9), type B2 (n=10), type B3 (n=5) and type C (n=7). In univariate analysis for overall survival, disease stage (P=0.001), tumor size (P=0.017) and the extent of surgical resection (P<0.001) were prognostic factors. Regarding the multivariate analysis, only the extent of the surgical resection (P<0.001) was the independent prognostic factor and non-surgical treatment had a negative influence on the survival. The 5-year and 10-year overall survival rates were 70.8% and 62.9%, respectively. Conclusion: Complete surgical resection is the most important prognostic factor in patients with thymic epithelial tumors.

    [Show abstract] [Hide abstract] ABSTRACT: Paratesticular sarcomas have happened rarely. Due to the infrequency of this malignant disease and its diverse histopathologic subtypes, no standard treatment would be available. Multiple treatments have reported in literature with different results. We have reported a 55 years old man with a 30 years history of paratesticular mass. After multiple operations, radical orchiectomy has revealed liposarcoma. The patient has been receiving 50 Gy radiation to the scrotum and inguinal area. After 18 months follow up, the patient was well and disease free. He has shown good response to surgery and radiotherapy, so we have reported the disease and its clinical course.

    [Show abstract] [Hide abstract] ABSTRACT: Background: This two-arm, randomized clinical study aimed to compare efficacy between topical Alpha ointment and topical hydrocortisone cream (1%) in the healing of radiation-induced dermatitis in breast cancer patients. Methods: The inclusion criteria comprised newly pathologically proven, locally advanced breast cancer (treated with modified radical mastectomy followed by sequential adjuvant treatments, including chest wall radiotherapy [45-50.4 Gy]) and grade 2 and/or 3 chest wall dermatitis. The exclusion criteria were comprised of any underlying disease or medications interfering with the wound healing process, previous history of chest wall radiotherapy, and concurrent use of chemotherapy. Sixty eligible patients were randomly assigned to use either topical Alpha ointment (study arm, n=30) or topical hydrocortisone cream (1%) (control arm, n=30) immediately after receiving a total dose of 45-50 Gy chest wall radiotherapy. Results: The mean radiation dose was 49.1 Gy in the control arm and 48.8 Gy in the study arm. The mean dermatitis area was 13.54 cm2 in the control arm and 17.02 cm2 in the study arm. Topical Alpha ointment was more effective on the healing of radiation-induced dermatitis than was topical hydrocortisone cream (1%) (P=0.001). This effect was significant in the second week (P=0.007). In addition, Alpha ointment decreased the patients’ complaints such as pain (P<0.001), pruritus (P=0.009), and discharge (P=0.010) effectively and meaningfully. Conclusion: Topical Alpha ointment was more effective on the healing of radiation-induced dermatitis than was topical hydrocortisone cream (1%) in our patients with breast cancer.

    [Show abstract] [Hide abstract] ABSTRACT: Introduction. This study aimed to report the characteristics, prognostic factors, and treatment outcomes of 54 patients with primary gastric lymphoma. Materials and Methods. This retrospective study was carried out by reviewing the medical records of 54 adult patients diagnosed at a tertiary academic hospital. All the patients were treated with curative intent. Forty-four patients (81.5%) underwent gastrectomy followed by adjuvant chemotherapy and/or radiotherapy, whereas 10 ones (18.5%) were treated with chemotherapy alone or with radiotherapy. Results. The study was conducted on 25 males and 29 females with the median age of 50 years. Diffuse large B-cell lymphoma (DLCL) (67%) and Mucosa Associated Lymphoid Tissue (MALT) lymphoma (26%) were the most common histologic types. Besides, 36 (59%), 16 (30%), 5 (9%), and 1 (2%) patients were in stages I, II, III, and IV, respectively. The 5-year disease-free survival and overall survival were 64.7% and 67%, respectively. In univariate analysis for overall survival, International Prognostic Index (IPI) (), the WHO performance status (), Ann Arbor stage (), age (), and LDH serum level () were the prognostic factors. Conclusion. Gastric lymphoma tends to present in early stage of the disease and has a favorable outcome.

    [Show abstract] [Hide abstract] ABSTRACT: This study aimed to investigate local control and survival rates following abdominoperineal resection (APR) compared with low anterior resection (LAR) in lower and middle rectal cancer. In this retrospective study, 153 patients with newly histologically proven rectal adenocarcinoma located at low and middle third that were treated between 2004 and 2010 at a tertiary hospital. The tumors were pathologically staged according to the 7th edition of the American Joint Committee on Cancer (AJCC) staging system. Surgery was applied for 138 (90%) of the patients, of which 96 (70%) underwent LAR and 42 were (30%) treated with APR. Total mesorectal excision was performed for all patients. In addition, 125 patients (82%) received concurrent (neoadjuvant, adjuvant or palliative) pelvic chemoradiation, and 134 patients (88%) received neoadjuvant, adjuvant or concurrent chemotherapy. Patients' follow-up ranged from 4 to 156 (median 37) months. Of 153 patients, 89 were men and 64 were women with a median age of 57years. One patient (0.7%) was stage 0, 15 (9.8%) stage I, 63 (41.2%) stage II, 51 (33.3%) stage III and 23 (15%) stage IV. There was a significant difference between LAR and APR in terms of tumor distance from anal verge, disease stage and combined modality therapy used. However, there was no significant difference regarding 5-year local control, disease free and overall survival rates between LAR and APR. LAR can provide comparable local control, disease free and overall survival rates compared with APR in eligible patients with lower and middle rectal cancer.

    [Show abstract] [Hide abstract] ABSTRACT: This study aimed to report the characteristics, prognostic factors and treatment outcome of 223 patients with glioblastoma multiforme (GBM). This retrospective study was carried out by reviewing the medical records of 223 adult patients diagnosed at a tertiary academic hospital between 1990 and 2008. Patients' follow up ranged from 1 to 69months (median 11months). Surgery was attempted in all patients in whom complete resection in 15 patients (7%), subtotal resection in 77 patients (34%), partial resection in 73 patients (33%) and biopsy alone in 58 patients (26%) were done. In addition, we performed a literature review of PubMed to find out and analyze major related series. In all, we collected and analyzed the data of 33 major series including more than 11,000 patients with GBM. There were 141 men and 82 women. The median progression free- and overall survival were 6 (95% CI=5.711-8.289) and 11 (95% CI=9.304-12.696) months respectively. In univariate analysis for overall survival, age (P=0.003), tumor size (P<0.013), performance status (P<0.001), the extent of surgical resection (P=0.009), dose of radiation (P<0.001), and adjuvant chemotherapy (P<0.001) were prognostic factors. However, in multivariate analysis, only radiation dose, extent of surgical resection, and adjuvant chemotherapy were independent prognostic factors for overall survival. The prognosis of adult patients with GBM remains poor; however, complete surgical resection and adjuvant treatments improve progression-free and overall survival.

    [Show abstract] [Hide abstract] ABSTRACT: Background Breast cancer is the most common cancer and the leading cause of cancer death among the women worldwide. The risk of local and distant recurrence is the highest during the first two years following the initial treatment. Very late relapse (after 12 years) is uncommon in breast cancer survivors. Methods Herein, we report the characteristics and outcomes of 6 such cases of breast cancer. Results The mean age of the patients was 40.1 years (range 30-57) and the mean disease free survival was 19.6 years. Conclusion Late relapse is not so common in breast cancer but can occur in any stage. Therefore, we suggest life-time follow up for every patient with breast cancer.

    [Show abstract] [Hide abstract] ABSTRACT: BACKGROUND: Since the advent of magnetic resonance imaging, metal artifacts have posed an important diagnostic problem in different fields of medicine. However, this has not been systematically studied in patients undergoing surgery for brain tumors. OBJECTIVE: This study was planned to assess whether metal artifacts can occur in patients undergoing brain surgery without metallic implants. METHODS: Of 40 individuals who could be included because of having a pre- and postoperative MRI and a postoperative computed tomography (CT) scan or a conventional skull X-ray for the detection of metallic artifacts, 26 patients agreed to participate in this study and gave informed consent. RESULTS: Twenty-six subjects, 12 males and 14 females, with an age range of 12 to 54 years, were included in the study. Four patients were found to have gross metal particles in their postoperative brain CTs and were excluded. Of the remaining 22 subjects, 7 patients (31.8%) had metallic artifacts. CONCLUSION: Our study showed that simple bone drilling or chiseling during surgical manipulation of skull bones may result in separation of very tiny metal particles which can remain in the surgical site and cause artifacts in postoperative MRIs. This finding appeared to be independent of factors such as age, sex, tumor/incision site, tumor size, pathologic tumor type, total radiation dose, operation-MRI time interval and sequence of MRI.
