AIMS: Osteoradionecrosis (ORN) is a serious toxicity of head and neck radiotherapy. It predominantly affects the mandible. Extra-mandibular ORN is rare. The aim of this study was to report the incidence and outcomes of extra-mandibular ORNs from a large institutional database. MATERIALS AND METHODS: In total, 2303 head and neck cancer patients were treated with radical or adjuvant radiotherapy. Of these, extra-mandibular ORN developed in 13 patients (0.5%). RESULTS: Maxillary ORNs (n = 8) were a consequence of the treatment of various primaries (oropharynx = 3, sinonasal = 2, maxilla = 2, parotid = 1)...

Radiotherapy of the head and neck can often lead to complications and side effects, including osteoradionecrosis and soft tissue necrosis. One relatively well-established method of treating osteoradionecrosis includes the PENTOCLO protocol, which consists of Pentoxyllifylline, Tocopherol, and Clodronate. Despite its success in the treatment of osteoradionecrosis, the effectiveness of components of the PENTOCLO protocol in treating soft tissue necrosis of the head and neck is underexplored. This case study reviews the successful treatment of a pyriform sinus ulcer that developed after the use of radiotherapy in treating a T3N2b squamous cell carcinoma...

INTRODUCTION: The Pentoxifylline, Tocopherol and Clodronate protocol (PENTOCLO) showed promising results for jaw osteoradionecrosis (ORN) management. However, the clinical and radiological improvements are often delayed, leading to unwanted long-term treatment, with potential loss of opportunity for more radical surgical treatments. Our objective was to assess the diagnosis performance of 18 F-FDG PET/CT to early predict ORN response to the PENTOCLO protocol. MATERIALS AND METHODS: All patients from our center who were treated with the PENTOCLO protocol and with a 18 F-FDG PET/CT performed at diagnosis and three months after the end of antibiotherapy were retrospectively included...

BACKGROUND: Treatment of osteoradionecrosis (ORN) is not a straightforward task, and it is unpredictable. However, a combination of pentoxifylline; an antioxidant drug, and tocopherol (vitamin E) works as a potent antifibrotic agent and have shown recently both significant and impressive results. AIMS: This scoping review aims to investigate the most prescribed regimen of pentoxifylline and tocopherol with/without clodronate for the management of ORN. METHODS: Ovid MEDLINE and EMBASE databases were used to retrieve eligible studies using planned search keywords...

AIMS: Medical management of osteoradionecrosis (ORN) via pentoxifylline, tocopherol (PENTO) and clodronate (PENTOCLO) has shown both promise and early positive outcomes. We aimed to determine clinical outcomes for patients with established ORN managed solely via PENTO or PENTOCLO. METHODS: The study retrospectively reviewed and collected data from the medical records of 169 patients diagnosed with ORN and treated via medical management. Patients that received any additional interventions such as surgery or hyperbaric oxygen were not included...

Radiation therapy is an important and commonly used treatment modality for head and neck cancers. Osteoradionecrosis (ORN) is a potential debilitating complication of treatment, which most commonly affects the mandible. Management strategies are tailored to the severity of disease. Medical management including oral rinses, irrigations, antibiotics, and pharmacological treatments is viable for mild-to-moderate ORN. More severe disease is best addressed with a combination of medical management and surgical intervention aimed at aggressively removing devitalized tissue until bleeding bone is encountered and reconstructing the soft tissue and bone defect...

PURPOSE: Radiation-induced (RI) plexopathy is a rare peripheral nerve injury after radiation therapy for cancer. No treatment has been shown to slow its progression. A pentoxifylline-vitamin E combination significantly reduced RI fibrosis, and its association with clodronate (PENTOCLO) allowed healing of osteoradionecrosis and reduction of neurologic symptoms in phase 2 trials. METHODS AND MATERIALS: A placebo-controlled, double-blind trial conducted in adults with RI limb plexopathy without cancer recurrence, randomized in 2 arms to PENTOCLO (pentoxifylline 800 mg, tocopherol 1000 mg, clodronate 1600 mg 5 days per week) or triple placebo...

PURPOSE: Calcinosis cutis is an anecdotal local injury seen long after irradiation in cancer survivors. Our purpose was to shed light on this little studied and potentially serious ulceration. CASES: We report two cases of severe perineal-sacral infection with hard lesions, one decade after anorectal cancer irradiation. CT-scans showed extensive calcification and soft tissue inflammation, but previous radiation therapy was overlooked and the diagnosis was not made for several months after various tests, including biopsy...

OBJECTIVES/HYPOTHESIS: PENTOCLO treatment, associating pentoxifylline, tocopherol, and clodronate, resolves radiation-induced fibrosis. The main aim of the present study was to prospectively assess efficacy in mandibular osteoradionecrosis (ORN). STUDY DESIGN: Prospective cohort study. METHODS: Twenty-seven patients with mandibular ORN were included in the Pentoclauvergne Study between January 2014 and February 2016. After an initial 28-day phase of antibiotic, antifungal, and corticosteroid therapy, they received the PENTOCLO association daily until cure or a maximum of 24 months...

Osteoradionecrosis of the jaws (ORNJ) is a late complication of head and neck irradiation estimated at around 3% of irradiated patients. The PENTO protocol (Pentoxyfilline and Tocopherol), with the eventual adjunction of Clodronate (PENTOCLO), showed interesting results even in advanced ORNJ. The current literature does not describe the long-term outcomes and particularly after the completion of the protocol. The PENTO or PENTOCLO protocol should be prescribed as a life-long treatment or the outcome should be monitored at least as long as the duration of the protocol after its end...

INTRODUCTION: Osteoradionecrosis (ORN) of the mandible is a painful and debilitating condition occurring after radiotherapy to the head and neck to treat cancer. For decades, hyperbaric oxygen (HBO) has formed the mainstay of the early management of ORN. Literature about the efficacy of HBO is contentious. Recently, Oral and Maxillofacial surgical units in France and UK have trialled a combination of medications to treat ORN, also known as PENTOCLO (PENtoxifylline+TOcopherol±CLOdronate)...

A significant complication of radiotherapy to the head and neck for cancer treatment is osteoradionecrosis (ORN) of the jaws. The management of ORN can be complex and often requires a multimodality approach. Nonsurgical treatments with or without adjunct measures and surgical interventions have all been employed on the basis of staging of the disease process. New theories on the pathophysiology of ORN have led to the identification of novel treatment modalities, including pharmacologic management using pentoxifylline, tocopherol, and clodronate (together referred to as "Pentoclo")...

BACKGROUND: Osteoradionecrosis (ORN) of the temporal bone is a complication of radiation therapy that is extremely challenging to manage. METHODS: We report the case of a patient treated at our institution and present a review of the literature. RESULTS: A 52-year-old woman presented with ORN of the temporal bone 20 years after radiation therapy for an ipsilateral parotid tumor. She failed conservative management, including serial debridements, oral and topical antibiotics/antifungals, and aural lavage...

INTRODUCTION: Osteoradionecrosis (ORN) is a severe, generally irreversible complication of radiotherapy due to failure of healing. The pentoxifylline-tocopherol combination decreases the superficial fibrosis induced by radiotherapy. Potentiation by Clodronate (PENTOCLO) appears to be effective in ORN of the mandible. The objectives of this study were to evaluate the efficacy and safety of PENTOCLO to treat osteoradionecrosis of the mandible. METHODS: Retrospective study of 27 patients with a mean age of 65±12 years, managed for ORN of the mandible secondary to irradiation for head and neck cancer, treated by the PENTOCLO protocol between January 2010 and March 2011...

INTRODUCTION: Because of the improvement of cancer prognosis, long-term damages of treatments become a medical and public health problem. Among the iatrogenic complications, neurological impairment is crucial to consider since motor disability and pain have a considerable impact on quality of life of long cancer survivors. However, radiation-induced neuropathies have not been the focus of great attention. The objective of this paper is to provide an updated review about the radiation-induced lesions of the peripheral nerve system...

PURPOSE: Osteoradionecrosis (ORN) is a nonhealing wound of the bone that is difficult to manage. Combined treatment with pentoxifylline and vitamin E reduces radiation-induced fibrosis and ORN with a good prognosis. We previously showed that the combination of pentoxifylline and vitamin E with clodronate (PENTOCLO) is useful in healing sternocostal and some mandibular ORN. Is PENTOCLO effective in ORN of poor prognosis? METHODS: 54 eligible patients previously irradiated for head and neck cancer (among 72 treated) a mean 5 years previously received exteriorized refractory mandibular ORN for 1...

Postoperative fibrosis (POF) is a rare, localized, and irreversible delayed effect of surgery, described in numerous tissues and organs. Is this fibrotic process amenable to therapeutic intervention? A synthesis of various clinical and histopathological aspects, and of cellular and molecular process regulation is described. In summary, there exists a prefibrotic chronic inflammatory phase, a constituted and cellular phase, and lastly a matricial densification and remodelling phase. The respective phases and the roles played over time by the main protagonists, namely myofibroblasts, extracellular matrix and growth factor (TGFbeta1) are clarified...

Radiation-induced (RI) peripheral neuropathy is a rare and severe delayed complication of radiotherapy that is spontaneously irreversible, with no standard of treatment. We previously developed a successful antioxidant treatment in RI fibrosis and necrosis. Two patients with progressive worsening RI lumbosacral polyradiculopathy experienced over several years a significant clinical improvement in their neurological sensorimotor symptoms with long-term pentoxifylline-tocopherol-clodronate treatment, and good safety...
