RESUMEN
Breast radiotherapy during pregnancy is a matter of debate as both the efficacy of treatment and the safety of the developing fetus should be considered. Currently there is not enough data to support the safety of in-utero exposure to radiation even with modern radiotherapy techniques. So it is highly recommended that breast radiotherapy is postponed to after delivery, though it might be considered in very selected patients according to risk-benefit assessment.

Purpose: This article aims to study the effect of Low-Level Laser Therapy (LLLT) on arm lymphedema in patients who have breast cancer. Methods and Materials: Twenty-three patients were selected in a nonrandomized phase-2 clinical trial. After measuring the circumference of the affected and unaffected limbs at 6-points, the volume of the limbs, the degree of mental symptoms on visual analog scale by the patient upon entering the study, and performing an ultrasound on the patient's axilla to locate the fibrotic areas, a low-level laser device at a therapeutic dose of 2 J/cm2 was used to treat the patients three times a week for 4 weeks, and after an 8-week gap, for another similar period. Measurement of circumference and volume of affected and unaffected limbs and mental symptoms were carried out at the end of the 4th week, the beginning of the 12th week, and the end of the 16th week, and the obtained results were compared with those before the treatment. Results: We noted that the average reductions in the circumference and volume of the affected limb, as compared with the unaffected limb, were about 16% and 21.7%, respectively, and improvement in the patient's mental symptoms was about 32%. Another notable observation was the great enthusiasm of most patients to continue their treatment, particularly from the second cycle onward. Conclusions: LLLT can, at least in association with current standard methods, be used for arm lymphedema to introduce further reductions in pain and volume.
RESUMEN
Background: Brachytherapy in treatment of endometrial cancer patients is growing and therefore, evaluation of more feasible schedule has become of great importance. The purpose of current study was to evaluate the complications of accelerated short course high dose rate intravaginal brachytherapy (HDR IVB), a new brachytherapy approach which is a more feasible treatment option in developing countries. Method: From 2017 to 2018, 54 patients diagnosed with endometrial cancer and FIGO stages IA to IIB who underwent total abdominal hysterectomy with a bilateral salpingo-oophorectomy were enrolled in present study. They were treated with a total dose of 25 Gy in 5 fractions which was prescribed daily. A dose of 5 Gy was prescribed at a depth of 0.5 cm in the upper third and middle third of vagina. Adverse effects related to organs at risk consist of bladder, vagina and rectum were documented based on the Common Terminology Criteria for Adverse Events v3.0 (CTCAE v3.0). Results: The accelerated short course HDR IVB was well tolerated and no grade 3 or higher toxicities was reported for patients during the follow up period. There were no chronic rectal toxicities and only one patient showed chronic urinary toxicities. However, the incidence rate of vaginal toxicities at the end of 4-month and 8-month follow up periods was higher than acute toxicities and significantly lower in elderly group compared to younger group. Conclusion: Overall, the accelerated HDR IVB was safe and was well tolerated in endometrial cancer patients and the incidence rate of undue complications were equal, if not less, in elderly patients compared to the younger ones.

PURPOSE: Radiation received by the testes in the course of radiotherapy for rectal cancer may cause oligospermia and azospermia. We sought to determine the dose to the scrotum and testes with thermoluminescence dosimetry (TLD), and compare it to the dose calculated by 3D planning software. METHODS: The TLDs were fixed to the scrotum in six points anteriorly and posteriorly in two fractions of radiotherapy. All patients received a 50-50.4â¯Gy total dose in prone position with 3D-planning. The average dose of TLD measurements was compared to the average of 6 relevant point doses calculated by the planning software. RESULTS: The mean scrotal dose of radiation in 33 patients as measured by TLD was 3.77â¯Gy (7.5% of the total prescribed dose), and the mean of point doses calculated by the planning software was 4.11â¯Gy (8.1% of the total dose), with no significant difference. A significant relationship was seen between the position of the inferior edge of the fields and the mean scrotal dose (Pâ¯=â¯.04). Also body mass index (BMI) was inversely related with the scrotal dose (Pâ¯=â¯.049). CONCLUSION: We found a dose of about 4â¯Gy received by the scrotum and testes from a total prescribed dose of 50â¯Gy in the radiotherapy of rectal carcinoma patients, with TLD measurements confirming testicular dose estimations by the planning software. This dose could be significantly harmful for spermatogenesis. Thus careful attention to the testicular dose in radiotherapy of rectal cancer for men desiring continued fertility is a necessity.

PURPOSE: Skin cancers are the most common human malignancy with increasing incidence. Currently, surgery is standard of care treatment for non-melanoma skin cancers. However, brachytherapy is a growing modality in the management of skin cancers. Therefore, we aimed to assess the outcome of patients with non-melanoma skin cancers treated by high-dose-rate (HDR) brachytherapy with surface mold technique. MATERIAL AND METHODS: In this prospective study, we recruited patients with basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) of the skin who were candidates for definitive or adjuvant brachytherapy during 2013-2014. Alginate was used for making the individualized surface molds for each patient. Patients were treated with afterloading radionuclide HDR brachytherapy machine, with a total dose of 30-52 Gy in 10-13 fractions. Participants were followed for 2 years for radiation toxicity, cosmetic results, and local failures. RESULTS: A total of 60 patients (66.7% male; median age, 71 years) were included, of which 42 (70.0%) underwent definitive radiotherapy. Seventy-five percent of lesions were BCC. The mean total dose was 39.6 ± 5.4 Gy. Of patients in definitive group, 40/42 (95.2%) experienced complete clinical response after 3 months. The recurrence rate was 2/18 (11.11%) and 1/42 (2.38%) in adjuvant and definitive groups, respectively. The percentage of grade 3-4 acute (3-month post-treatment) and late toxicities (2 years post-treatment) was 6.7% and 0%, respectively. The cosmetic results were good/excellent in 96.2% of patients after 2 years of follow-up. CONCLUSIONS: With appropriate patient selection and choosing as lowest dose per fraction as possible, HDR brachytherapy with customized surface molds yields good oncological and cosmetic results for the treatment of localized skin BCC and SCC.
RESUMEN
Cervical cancer is one of the most common gynecological cancers in Iranian women. This study was initiated to assess whether the combination of paclitaxel and cisplatin with radiation might feasible for these patients. The aim was to assess tumor response and toxicity of weekly cisplatin and paclitaxel along with radiotherapy in the treatment of cervical cancer. Women with primary untreated squamous cell carcinoma of the cervix with FIGO stages IB2 to IIIB were treated with weekly injections of cisplatin 30 mg/m2 and paclitaxel 35 mg/m2 for 5-6 weeks along with radiotherapy. A total of 25 patients were enrolled in this study who completed the intended treatment. Disease was assessed prior to treatment by pelvic examination and contrast enhanced MRI of the abdomen and pelvis. Response was assessed 1 month after completion of treatment by physical examination and 3 months after also by MRI.Toxicity was assessed and was graded using RTOG grading. There was a complete response rate of 84% after 3 months. The major toxicity was grade 1 and 2 anemia (92%). The mean duration of treatment was 58 days. In conclusion, combination chemotherapy with cisplatin and paclitaxel along with radiotherapy in patients with locally advanced squamous cell carcinoma of cervixwas well tolerated, in contrast to other studies, but it seems that there was no increase in tumor response and progression free survival with this treatment regimen.

Bckground: Adjuvant radiation therapy is commonly administered following breast-conserving surgery for breast cancer patients. Hypofractionated radiotherapy can significantly reduce the waiting time for radiotherapy, working load on machines, patient visits to radiotherapy departments and medical costs. Material/Methods: Fifty-two patients with operable breast cancer (pT1-3pN0M0) who underwent breast conservation surgery in Tehran Cancer Institute during January 2011 to January 2012, were randomly assigned to undergo radiotherapy in two arms (hypofractionated radiotherapy arm with 30 patients, dose 42.5 Gy in 16 fractions; and conventional radiotherapy arm with 22 patients, dose 50 Gy in 25 fractions). W compared these two groups in terms of overall survival, locoregional control, late skin complications and cosmetic results. Results: At a median follow-up of 52.4 months (range: 064 months), the follow-up rate was 82.6%. Overall, after 60 months, there was no detectable significant differences between groups regarding cosmetic results (p = 0.857), locoregional control or survival. Conclusions: The results confirm that hypofractionated radiotherapy with a subsequent boost is as effective as conventional radiotherapy, is well-tolerated and can be used as an alternative treatment method following breast conservation surgery.
RESUMEN
OBJECTIVE: Invasive cervical cancer (ICC) is the fourth most common cancer among women worldwide. Cervical screening programs have reduced the incidence and mortality rates of ICC. We studied the cost-effectiveness of different cervical screening strategies in the Islamic Republic of Iran, a Muslim country with a low incidence rate of ICC. METHODS: We constructed an 11-state Markov model, in which the parameters included regression and progression probabilities, test characteristics, costs, and utilities; these were extracted from primary data and the literature. Our strategies included Pap smear screening and human papillomavirus (HPV) DNA testing plus Pap smear triaging with different starting ages and screening intervals. Model outcomes included lifetime costs, life years gained, quality-adjusted life years (QALY), and incremental cost-effectiveness ratios (ICERs). One-way sensitivity analysis was performed to examine the stability of the results. RESULTS: We found that the prevented mortalities for the 11 strategies compared with no screening varied from 26% to 64%. The most cost-effective strategy was HPV screening, starting at age 35 years and repeated every 10 years. The ICER of this strategy was $8,875 per QALY compared with no screening. We found that screening at 5-year intervals was also cost-effective based on GDP per capita in Iran. CONCLUSION: We recommend organized cervical screening with HPV DNA testing for women in Iran, beginning at age 35 and repeated every 10 or 5 years. The results of this study could be generalized to other countries with low incidence rates of cervical cancer.

We treated 34 radiation-induced superficial fibrotic lesions with pentoxifylline and vitamin E for 3 months. Mean surface area of the lesions decreased from 112 to 65 cm(2) after treatment (P<0.001). A subgroup of 21 fibrotic lesions received the medications for 6 months, in which surface area decreased from 80 to 27 cm(2) (P<0.001). Pentoxifylline-vitamin E combination improved radiation-induced fibrosis.

BACKGROUND: Cervical cancer is the fourth most common cancer among women worldwide. Organized cervical screening and vaccination against human papilloma virus (HPV) have been successful interventions for prevention of invasive cervical cancer (ICC). Because of cultural and religious considerations, ICC has low incidence in Iran and many other Muslim countries. There is no organized cervical screening in these countries. Therefore, ICC is usually diagnosed in advanced stages with poor prognosis in these countries. We performed a priority setting exercise and suggested priorities for prevention of ICC in this setting. METHODS: We invited experts and researchers to a workshop and asked them to list important suggestions for ICC prevention in Iran. After merging similar items and removing the duplicates, we asked the experts to rank the list of suggested items. We used a strategy grid and Go-zone analysis to determine final list of priorities for ICC prevention in Iran. RESULTS: From 26 final items suggested as priorities for prevention of ICC, the most important priorities were developing national guidelines for cervical screening and quality control protocol for patient follow-up and management of precancerous lesions. In addition, we emphasized considering insurance coverage for cervical screening, public awareness, and research priorities, and establishment of a cervical screening registry. CONCLUSION: A comprehensive approach and implementation of organized cervical screening program is necessary for prevention of ICC in Iran and other low incidence Muslim countries. Because of high cost for vaccination and low incidence of cervical cancer, we do not recommend HPV vaccination for the time being in Iran.

BACKGROUND: We performed a cross-sectional multicentre study to assess the prevalence of lymphedema after breast cancer treatment in Iran. PATIENTS AND METHODS: All female breast cancer patients who attended our follow-up clinics four or more years after their surgery with no sign of disease were asked to participate in this study. Lymphedema was defined as an increase of 10% in the circumference of the arm on the involved side compared to the opposite arm. RESULTS: The total number of patients participating in this study was 355. The prevalence of lymphedema in the study patients was 17.5%, with the rate varying significantly (between 4 and 21%) among the three study centres (p = 0.007). The mean number of months post surgery was larger for patients with lymphedema (84 months) than for those without (79 months), though this was not statistically significant (p > 0.1). The relationships of various treatment factors and the education levels of the patients to the presence of lymphedema were also evaluated. None of the observed differences were statistically significant aside from those for the type of surgery (mastectomy vs. conservative surgery, p = 0.055), treatment with radiotherapy (p = 0.099), and prescription of a supraclavicular radiation field (p = 0.057), which were only just significant. CONCLUSION: The rate of lymphedema in our patients was 17.5%, ranging from 4 to 21% in different study centres. Time post surgery, treatment with radiotherapy and the technique used, and nodal radiation seem to be factors that are related to this large variation.

INTRODUCTION: Objective cutaneous metastasis from carcinoma of the uterine cervix is an uncommon occurrence. The outcome of patients with skin metastasis is usually poor as they are often associated with locoregional recurrence. This metastasis impairs the quality of life and shortens survival. Consequently, physicians should be aware of the possible existence of skin metastasis in cervical cancer. Clinical suspicion should lead to a careful additional evaluation whenever a cutaneous nodule presents in the course of the disease. CASE REPORT: We report a rare case of metastasis from squamous cell carcinoma of cervix to the umbilicus. The patient was diagnosed with stage IIB FIGO. Four months after chemoradiation patient presented with a nodule in the umbilical region. Biopsy performed and metastatic squamous cell carcinoma was diagnosed. Patient underwent salvage therapy with paclitaxel and carboplatin. CONCLUSION: To the best of our knowledge, this is a rare reported occurrence of umbilical metastasis in cervical cancer without prior laparotomy or laparoscopy. This metastatic lesion has a grave prognosis and the mean survival is about 3 months like our case.
