Irradiation to treat head and neck cancer, causing chronic tissue damage, is associated with the development of vascular disease. Interest has risen over the effects of radiotherapy on major vessels, due to its high morbidity and mortality rate. However, small-vessel disease has been poorly studied and described.

Case Report:

We present a case of a patient with bilateral necrosis of the anterior third of the tongue, occurring 3 years after chemoradiotherapy treatment for squamous cell carcinoma of the floor of the mouth. Contrast-enhanced CT scan showed multiple areas of stenosis concerning both external carotid arteries and their branches, and total opacification of lingual arteries. Conservative management was performed, with auto-amputation on the fifth day, which allowed healing by secondary intention.

Necrosis of the tongue appears as a rare late complication of radiotherapy, possibly due to its acceleration effect on the atherosclerosis process. Following small-vessel disease, one can assume a higher potential risk of major-vessel disease, highlighting the importance of a routine assessment and prophylaxis of thrombotic events.

Recent Developments in cancer treatment could provide a better survival rate for Acute Lymphoblastic Leukemia (ALL) patients. Survivors faced different long term complication after treatment, for instance cardiac, neurologic and kidney complications. Assessment of the late complications could be useful in the optimization of treatment protocols. The objective of this study was to evaluate the late kidney complications, renal function in ALL patients after therapy.Material &

In this study, we used 46 children. The treatment preformed based on ICBFM protocol. The mean age at the start of the treatment was 53±23 and the mean follow up time was 48±11 months. The tubular damage in these patients was evaluated by urinary NGAL level and the renal function was assessed by GFR.

in this study 56.7% of the patients were male. The NGAL level shows abnormally high in 8.9% of patients and the mean urine NGAL was 63±113ng/mL. Also, the mean GFR at the time of the diagnosis and at the time of the start of the follow up were 102.8 ±25.6 mL/min/1.73 m2 and 93.6 ±29.1 mL/min/1.73 m2, respectively. The study indicated GFR were less than 60 mL/min/1.73 m2 in 13.3% of patients.

this study indicated the long term follow up of the ALL survivors for kidney disorders are an important manner. The urinary NGAL level shows that 8.9% of the patients are tubular damage by using this treatment protocol. The study concluded that ICBFM protocol is a safe protocol with little long term damage.

Hematopoietic stem cell transplantation (HSCT) is currently the only curative treatment for acute leukemia. As HSCT improves the long-term survival, it is necessary to assess the late-onset complications affecting the quality of life following HSCT.
Subjects and The study included 122 patients (65 male, 57 female) with leukemia (72 AML and 50 ALL) who received transplants from fully- matched siblings, unrelated donors and unrelated cord blood donors between February 2013 and August 2014 in Shariati Hospital. All study participants were over 18 years of age and had the minimum and maximum survival of 2 and 5 years, respectively. Patients who received HLA-haploidentical SCT were excluded from the study. All allogeneic recipients received busulfan and cyclophosphamide as conditioning regimen. Nobody received TBI-based conditioning regimen in this study.
Patients were evaluated for cardiovascular, vision, psychological, endocrine, fertility problems and secondary malignancies one year after transplantation.
Data were analyzed using SPSS 15.0. Mitral and tricuspid regurgitation (TR/MR) were the most common cardiac complications (n=12, 10.5%).Thirty-nine percent of patients had psychological problems, especially depression (34%). Cataract was observed in 13% of patients and 34% complained of dry eye. Symptomatic pulmonary changes were found in 13 patients (10.6%). None of the HSCT survivors had experienced fertility before study entry. According to LH and FSH levels, 15% and 9% of females had ovarian failure, respectively. Testosterone level was less than normal in 49(84%) men and, according to their FSH and LH level, 20 (41%) had secondary hypogonadism and 29 (59%) had primary gonadal dysfunction.
The results showed that patients who received Bu/Cy conditioning regimen experienced fewer late side effects such as cataract formation and hypothyroidism, compared to previous studies using TBI-based conditioning regimen.
