Purpose: Provision of general anaesthesia in areas remote from the operating room creates many difficult challenges especially if required for repeated radiotherapy in the prone position. This case illustrates these problems and some innovative solutions.
Clinical Features: A nine-year-old girl with medulloblastoma became extremely distressed whenever cobalt radiotherapy was attempted. Sedation with midazolam and high dose propofol infusion failed to achieve satisfactory conditions and caused concerns regarding airway management. The patient received a total of 37 endotracheal anaesthetics in the prone position using isoflurane in oxygen. Activated charcoal was used to scavenge anaesthetic vapors and adequate gas supplies were assured by connecting an "H' size tank to the oxygen pipeline inlet of the anaesthesia machine. Measurement of isoflurane in exhaust gases using gas chromatography confirmed the effectiveness of scavenging. No serious complications occurred related to repeated anaesthesia.
Conclusion: The methods and equipment described permitted safe delivery of repeated inhalation general anaesthesia for radiotherapy. The same methods could be applied to anaesthesia in other remote locations.

Purpose: Non-melanoma skin cancer (NMSC) is the most prevalent cancer worldwide, particularly affecting head and neck region. Surgical excision, especially Moh's microsurgery, is the gold standard for treatment. However, certain patients' factors, such as age, comorbidities, and tumor location, require alternative therapies.

Purpose: Pituitary neuroendocrine tumors (pitNETs) are benign tumors that may recur after surgical resection or persist following medical management. The objective of this study was to evaluate outcomes and toxicities of patients with pitNETs treated with stereotactic radiosurgery (SRS) at a single institution.
Methods: We completed a retrospective, single-institution study of patients with pitNETs treated with frame-based, single-fraction, cobalt-60 SRS between September 2005 and June 2023.

Primary treatment with brachytherapy for oral cancer is uncommon in large malignant lesions; however, it is preferred by radiation oncologists for initial and smaller-sized lesions in compromised anatomical locations. The purpose of this report is to introduce and discuss the fabrication of a customized brachytherapy applicator for a case of well differentiated squamous cell carcinoma (SCC) of the oral commissures using a radiotherapy thermoplastic mold (RTM). The RTM was molded into the shape of tongs and two acrylic wings were attached to these customized tongs to secure five high-dose radiotherapy catheter tubes.
