Assessment of Improved Organ at Risk Sparing for Advanced Cervix Carcinoma Utilizing Precision Radiotherapy Techniques

Abstract

Proton beam RT has significant potential to improve treatment related side effects in the bowel compared to photon beam RT in patients with advanced cervix carcinoma.

Neoadjuvant radiochemotherapy and surgery for advanced rectal cancer

“…One patient suffered delayed wound healing. Four patients (7%) reported some form of fecal incontinence, 6 patients complained about perianal pain, 1 patient about erectile dysfunction, and 3 patients had chronic diarrhea [5,7,8].…”

Simultaneous chemoradiation with cisplatin in a patient with recurrent cervical cancer undergoing hemodialysis

“…Radiation treatment consisted of five weekly fractions at 1.8 Gy for a total dose of 50.4 Gy (a total of 28 fractions) were given to the pelvic lymph nodes and former tumor region with a 7-field IMRT plan generated in order to decrease the dose to the small bowel [5]. A boost was given to the clipmarked region +3 mm margins with five weekly fractions of 1.8 Gy to a total of 16.2 Gy with a stereotactic technique [21].…”

Investigations on Parotid Gland Recovery after IMRT in Head and Neck Tumor Patients

“…The latter is driven by inverse planning approaches and computerized optimization modules which require certain input data [2,5,10,12,13,18,19,29,30,34,35]. Parotid gland sparing is one main motivation for IMRT in the head-and-neck region.…”
