Abstract

Background: To date, different kinds of treatment methods have been proposed for radiotherapy of cancer patients. Choosing the kind of treatment method affects the quality of the patient's treatment. This study aims to investigate the effect of the number of radiation treatment sessions on the dose received by the patient and the distribution of tumor dose and dose received by organs at risk in breast cancer radiation therapy. These results help us to select the appropriate treatment schedules for the treatment of left breast patients.
Methods: This prospective cross-sectional study was performed on the treatment plans of 35 patients with left breast cancer who referred to Isfahan Milad Hospital between July 2019 and April 2020. They were candidates for left breast radiation therapy. Also, these patients had no history of surgery or chemotherapy, and no supraclavicular or axillary lymph nodes were involved. Patients were treated with a conventional fraction regimen (CF) or hypofractionated (HF) treatment schedule. Different dosimetry parameters for the target and organ at risks such as conformity index, homogeneity index and mean dose were obtained from the dose-volume histogram plot. Finally, the results of both plans were compared with each other.
Results: The data obtained from this study indicate a decrease in the average dose of all organs in the hypo fractionated regimens compared to conventional plans. The differences between two plans were statistically significant for tumor, lung, and skin (P=0.0). Moreover, the maximum dose for the skin was also reduced when hypofractionated regimens were used. However, the values of the homogeneity index and conformity index of tumor in the two methods did not show a significant difference (P were 0.99 and 0.86, respectively).
Conclusion: In general, the results of the current study indicate that the hypofractionated regimen leads to a reduction in dosimetric factors compared to conventional fraction plans. It seems that this method can be used as an alternative treatment plan for breast cancer radiation therapy due to the reduced duration of the treatment period.

Background: With 6,020 new cases and 1,150 deaths annually in the United States, vulvar cancer is uncommon, resulting in age-adjusted incidence rates of 2.8 and 1.7 per 100,000 in white and black women, respectively. Vulvar cancer represents about 4% to 6% of malignancies of the female genital tract and 0.6% of all cancers in women. Vulvar cancer predominantly affects postmenopausal women, and it is the most common anogenital cancer in women with more than 70 years of age. HPV infection is associated with a significant number of vulvar cancers. Bartholin Gland carcinoma is a rare form of vulvar malignancy that accounts for less than 5% of all vulvar cancers and 0.001% of all genital cancers. The aim of this study was to report a rare case of Bartholin's cancer in a young patient.
Case Report: The patient was a 37-year-old woman p2l2 (history of two pregnancy and two delivery) who had complains of severe pain in perineal area and was referred to the gynecology emergency clinic, Ghaem Hospital, Mashhad University of Medical Sciences, Mashhad, Iran, in June 2020. In past medical history she had no previous history of medical illnesses or surgical interventions. She had swelling and pain in perineal area since one year ago. Bartholin Gland abscess was diagnosed and she received some oral antibiotics, but did not improve. On the last examination under anesthesia, a firm mass of about 3 cm was palpated in the third distal part of posterior vagina which was at the site of Bartholin Gland and was necrotic. The pathologic report of the mass biopsy confirmed the diagnosis of squamous cell carcinoma. The patient was underwent chemo radiation therapy. At a follow up visit about 5 month later she was cured completely and there was not any symptom of recurrence or metastasis.
Conclusion: In dealing with any patient with diagnosis of Bartholin Gland abscess, in the case of resistance to medical treatment, further evaluation and biopsy of the mass should be considered to rule out Bartholin's gland cancer.
