PURPOSE: Image-guided adaptive brachytherapy (IGABT) is currently state of the art in the comprehensive treatment of patients with cervical cancer. Here, we report mature clinical data regarding IGABT of cervical cancer in a large patient sample, examining clinical outcomes, manifestations of late toxicities, and dosimetric findings. METHODS: Between May 2012 and October 2020, we performed a total of 544 uterovaginal IGABT applications in 131 consecutive patients with biopsy-proven cervical carcinoma not suitable for surgery. The median duration of follow-up was 43 months. RESULTS: The estimated 3‑, 4‑, and 5‑year LC rates were 88.3% (95% confidence interval [CI] 81.1-95.5), 86.9% (95% CI 78.5-95.3), and 85.5% (95% CI 76-95%), respectively. The 3‑, 4‑, and 5‑year OS estimates were 72.66% (95% CI 63.64-81.69%), 68.9% (95% CI 59.15-78.66%), and 63.96% (95% CI 52.94-74.97%), respectively. Patients who received ≥ 5 cycles of chemotherapy had statistically significantly better 3‑year recurrence-free survival (RFS) compared to patients who completed <5 cycles (79.07% [95% CI 60.81-97.34] vs. 58.10% [95% CI 47.22-68.98]; p = 0.0185). We recorded manifestations of genitourinary and gastrointestinal toxicity grade ≥3 in 6.9% and 5.3%, respectively. CONCLUSION: Our mature long-term data on the treatment patients with locally advanced cervical cancer show that excellent treatment outcomes can be achieved with MRI-based IGABT, as well as acceptable late morbidity.

Carcinoma showing thymus-like elements (CASTLE) is an extremely rare malignant tumor of the thyroid gland and soft tissues of the neck with favorable prognosis. Histological features of the CASTLE are similar to thymic carcinoma, and it is assumed that it arises from the ectopic thymic tissue or the remnants of branchial pouches. The optimal treatment strategy is still uncertain because of the rarity of the tumor. The mainstay of treatment is surgery. The role of other modalities is unclear. We present a case report of a patient with locally advanced CASTLE of the thyroid gland who was not suitable for surgery and underwent radical radiotherapy with subsequent achievement of complete remission. We also present a literature review.

Lymphangiosarcoma, or Stewart-Treves Syndrome (STS), is a very rare skin angiosarcoma with poor prognosis, which usually affects the upper limbs of patients who underwent breast cancer surgery, including axillary dissection followed by radiotherapy (RT). Cutaneous lymphangiosarcomas, which account for approximately 5% of all angiosarcomas, usually originate in the limb with chronic lymphedema. Lymphatic blockade is involved in the onset of STS. RT contributes indirectly to an increased risk of developing STS by causing axillary-node sclerosis and resulting in a lymphatic blockade and lymphedema. Chronic lymphedema causes local immunodeficiency, which indirectly leads to oncogenesis. Currently, axillary nodes are no longer routinely irradiated after axillary dissection, which is associated with a reduction in the incidence of chronic lymphedema from 40% to 4%. The use of sentinel lymph node biopsy technique is also widespread and the associated risk of lymphedema is further reduced. Thus, the incidence of STS decreased significantly with improved surgical and radiation techniques. The overall prognosis of STS patients is very poor. Only early radical surgical removal, including amputation or disarticulation of the affected limb, or wide excision at an early stage offers the greatest chance of long-term survival. Only a few case reports and series with a small number of patients with lymphangiosarcoma can be found in the literature. We present a case report of the first diagnosed STS at our department in an effort to highlight the need of the consideration of developing lymphangiosarcoma in patients with chronic lymphedema.
