RESUMO

BACKGROUND AND PURPOSE: Radiotherapy (RT) is an essential treatment modality against cancer and becoming even more in demand due to the anticipated increase in cancer incidence. Due to the rapid development of RT technologies amid financial challenges, we aimed to assess the available RT facilities and the issues with achieving health equity based on current equipment compared to the previous reports from Iran. MATERIALS AND METHODS: A survey arranged by the Iran Cancer Institute's Radiation Oncology Research Center (RORC) was sent to all of the country's radiotherapy centers in 2022. Four components were retrieved: the reimbursement type, equipment, human resources, and patient load. To calculate the radiotherapy utilization rate (RUR), the Lancet Commission was used. The findings were compared with the previous national data. RESULTS: Seventy-six active radiotherapy centers with 123 Linear accelerators (LINACs) were identified. The centers have been directed in three ways. 10 (20 LINACs), 36 (50 LINACs), and 30 centers (53 LINACs) were charity-, private-, and public-based, respectively. Four provinces had no centers. There was no active intraoperative radiotherapy machine despite its availability in 4 centers. One orthovoltage X-ray machine was active and 14 brachytherapy devices were treating patients. There were 344, 252, and 419 active radiation oncologists, medical physicists, and radiation therapy technologists, respectively. The ratio of LINAC and radiation oncologists to one million populations was 1.68 and 4.10, respectively. Since 2017, 35±5 radiation oncology residents have been trained each year. CONCLUSION: There has been a notable growth in RT facilities since the previous reports and Iran's situation is currently acceptable among LMICs. However, there is an urgent need to improve the distribution of the RT infrastructure and provide more facilities that can deliver advanced techniques.

RESUMO

BACKGROUND: The most frequent physical finding in infertile men is varicocele, in which one of the mechanisms that can affect seminal parameters is oxidative stress. OBJECTIVE: Our study aimed, for the first time, to compare the efficacy of recombinant human follicle-stimulating hormone (rhFSH), human chorionic gonadotropin (HCG) and human menopausal gonadotropin (HMG) on sperm parameters and fertility after varicocelectomy. MATERIALS AND METHODS: 113 infertile men with varicocele were divided into four groups. Group A received HCG 5000 IU weekly, group B received HMG 75 IU three times a week, group C received rhFSH 75 IU three times a week and group D received no medical treatment after varicocelectomy. RESULTS: After three months, in group A sperm morphology improved (p=0.007), causing a 32% pregnancy rate. In group B, sperm motility (p=0.023) and morphology (p=0.014) improved, causing a 57% pregnancy rate. In group C, all of the investigated semen parameters increased (p<0.05), causing a 62.5% pregnancy rate. Only rhFSH improved sperm concentrations to >20×10(6) mL (p=0.027). In group D, sperm morphology increased (p=0.038), but other parameters remained unchanged and no pregnancies occurred. CONCLUSION: It can be concluded that drugs can reduce induction time for spermatogenesis and fertility in comparison with varicocelectomy alone. For these purposes, rhFSH is more effective than other drugs.
