Geldof NI, van Hulst RA, Ridderikhof ML, Teguh DN. Hyperbaric oxygen treatment for late radiation-induced tissue toxicity in treated gynaecological cancer patients: a systematic review. Radiat Oncol 2022; 17:164. [PMID: 36203216 PMCID: PMC9540739 DOI: 10.1186/s13014-022-02067-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2022] [Accepted: 05/06/2022] [Indexed: 11/10/2022] Open
Abstract
Purpose The aim of this study was to investigate the result of hyperbaric oxygen therapy (HBOT) in women with treated gynaecological malignancies who suffer from late radiation-induced tissue toxicity (LRITT). Moreover, which symptoms of LRITT benefit most from HBOT was evaluated as well. Material and Methods An online literature search was conducted using PubMed; Embase and the Cochrane Library. Studies were included if the study examined gynaecological cancer patients who had been treated with radiotherapy, who suffered from LRITT and who subsequently received HBOT. In addition, the outcome measures were based on examining the effects of HBOT. Results Twenty-one articles were included. The study investigating proctitis reported an improvement and three out of four studies investigating cystitis reported decreased complaints in women treated for gynaecological malignancies. In addition, all studies reported improvement in patients with wound complications and fifty percent of the studies reported better Patient Reported Outcome Measurements (PROMS) in women with gynaecological malignancies. Finally, all studies, except one related to pelvic malignancies reported reduced prevalence of symptoms for cystitis and proctitis and all studies reported better PROMS. However, only eleven studies reported p-values, nine of which were significant. Conclusion This study demonstrated that HBOT has a positive effect in women with gynaecological LRITT. Within the included patient group, gynaecological cancer patients with wound complications seem to benefit most from this treatment compared to other late side effects of LRITT.

Hyperbaric Oxygen Therapy for Suburethral Vaginal Mucosal Necrosis after Interstitial Irradiation for Recurrent Cervical Cancer. Case Rep Obstet Gynecol 2021; 2021:1737975. [PMID: 34540299 PMCID: PMC8448613 DOI: 10.1155/2021/1737975] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2021] [Accepted: 08/25/2021] [Indexed: 11/27/2022] Open
Abstract
Patients with gynecological malignancies can develop radiation injuries, such as cystitis, proctitis, and soft tissue necrosis which have approved indications for hyperbaric oxygen therapy (HBOT). A 76-year-old Japanese woman with vaginal recurrence of cervical cancer was treated with the high-dose rate interstitial brachytherapy. Twenty-one months after the irradiation, she developed radiation necrosis on the external urethral opening. Two cycles of HBOT were performed. HBOT consisted of delivering 100% oxygen for 60 minutes at 2.4 atmospheres absolute. Pressure exposure was performed once daily, 5 days a week for 6 weeks. Eventually, the necrotic mucosa was completely replaced by the normal mucosa. No adverse effects were observed. We successfully treated a case of late adverse events of radiation therapy with HBOT. It was noninvasive and appears to be a useful treatment option which should be considered standard treatment practice.

Abstract
Background and objectives Sarcomas are commonly managed by surgical resection combined with radiotherapy. Sarcoma treatment is frequently complicated by chronic wounds and late radiation tissue injury (LRTI). This study aims to gain insight in the use and results of hyperbaric oxygen therapy (HBOT) for radiation-induced complications following sarcoma treatment. Methods All sarcoma patients treated between 2006 and 2017 in one of the five centers of the Institute for Hyperbaric Oxygen in the Netherlands were included for retrospective analysis. Results Thirty patients were included, 18 (60.0%) patients were treated for chronic wounds and 12 (40.0%) for LRTI. Two patients with chronic wounds were excluded from analysis as HBOT was discontinued within five sessions. In 11 of 16 (68.8%) patients treated for chronic wounds, improved wound healing was seen. Nine of 12 (75.0%) patients treated for LRTI reported a decline in pain. Reduction of fibrosis was seen in five of eight patients (62.5%) treated for LRTI. Conclusions HBOT is safe and beneficial for treating chronic wounds and LRTI in the sarcoma population. Awaiting further prospective results, we recommend referring to HBOT centers more actively in patients experiencing impaired wound healing or symptoms of delayed radiation-induced tissue injury following multimodality sarcoma treatment.

Abstract
OBJECTIVE To evaluate the clinical value of endoscopic fibrin glue (FG) application therapy in treating hemorrhagic radiation cystitis (HRC). PATIENTS AND METHODS This is a single-cohort, prospective pilot study. We collected data from patients with HRC who were treated at our urology unit from May 2014 to December 2016. Patients with grade ≥2 HRC for whom conventional therapy and transurethral endoscopic electrocoagulation had failed were treated with endoscopic intravesical FG. The mean follow-up was 26.2 ± 9.78 months. Our analysis included data on patient demographics, pelvic malignancies, radiotherapy regimens, total dose of radiation received, time of onset and severity of hematuria, and previous intravesical management. Following FG intervention, patients' clinical status was defined as: (1) clinical response; absence of dysuria, urgency, and frequency; discontinuation of analgesic medication; and Foley catheter removal, but with ongoing hematuria grade <2; (2) complete response, clinical response, and no further hematuria; or (3) no response, no clinical response, and sustained hematuria. RESULTS A total of 20 patients (12 women and 8 men; mean age, 69 ± 7.5 years) were treated with 12 mL FG intravesically, using endoscopic application. Of the 20 patients, 16 (80%) had a complete response and 4 (20%) had a clinical response. In the case of four patients (20%), treatment was carried out twice. Mean hospital stay was 6 ± 2.5 days. The intervention showed good tolerability in all patients. No major adverse events were reported. Bladder spasms were the only minor adverse events reported in six patients (30%). CONCLUSION Application of FG is an effective, practical, affordable, and repeatable procedure for the treatment of grade ≥2 HRC.

Abstract
Objective This study aimed to investigate the impact of bladder volume on treatment planning and clinical outcomes of radiotherapy for patients with cervical cancer. Materials and methods One hundred and sixty-six patients with locally advanced cervical cancer were selected in this retrospective study. The patients were divided into four groups according to their average bladder volume during radiotherapy (external beam radiation therapy and intracavitary brachytherapy): group A: V<100 mL, group B: 100 mL≤V≤150 mL, group C: 150 mL<V≤200 mL, group D: V>200 mL. The bladder volume and the cumulative dose to planning target (D90), bladder (D2cc), rectum (D2cc), and sigmoid (D2cc) were calculated using the treatment planning system. Treatment outcomes including late adverse events (the maximum grade of radiation-induced proctitis and cystitis), the objective response rate of tumor and lymph node, overall survival (OS), and progression-free survival (PFS) were collected. Additionally, the correlation between bladder volume and the irradiated dose of organs at risk and treatment outcomes was analyzed. Results The median follow-up time was 28 months. The D90 and D2cc of the rectum in group A were the highest (P<0.05). The D2cc of the bladder in group D was the highest (P<0.05). There was no significant difference in the tumor and lymph node regression rate, OS, and PFS among the groups. The difference in the late radiation-induced proctitis and cystitis maximum grade among the four groups was statistically significant (P<0.001, P=0.022, respectively), with group A the most serious and group B the mildest. Conclusion For patients with cervical cancer, the bladder volume significantly affected the delivered dose to target, rectum, and bladder. When the bladder volume range was 100–150 mL, the rate of late radiation-induced proctitis and cystitis was low and the degree of reaction was mild. This is thought to be the optimum bladder volume for patients with cervical cancer during radiotherapy.

Abstract
The aim of the present study was to investigate the safety and efficacy of mesalazine suppository in the treatment of refractory ulcerative chronic radiation proctitis (CRP). In total, 10 refractory ulcerative CRP patients who did not respond to previous medical treatments were recruited for the present study and were treated with mesalazine suppository (0.5 g) twice daily for 24 weeks. For each patient, the severity of clinical symptoms and endoscopic appearance was assessed before and after the treatment. For symptom scoring, the reductions in the mean total symptom score (pre- vs. post-treatment, 8.20 vs. 0.90; P<0.01), rectal bleeding score (2.40 vs. 0.30; P<0.01), rectal pain score (2.00 vs. 0.50; P<0.01), stool frequency score (2.00 vs. 0.10; P<0.01) and tenesmus score (1.80 vs. 0.00; P<0.01) were all statistically significant. For mucosal damage scoring, there was a reduction in the mean scores for total scores (9.22 vs. 5.22; P<0.01), telangiectasia (2.78 vs. 1.89; P=0.009), edema (2.89 vs. 1.78; P=0.001) and ulceration (2.44 vs. 0.89; P=0.003). However, statistically reductions in the median symptom scores were not observed for stenosis (0.78 vs. 0.67; P=0.347) and necrosis (0.33 vs. 0.00; P=0.081). Furthermore, no adverse events were observed during and after the treatment. The topical mesalazine suppository may be a safe and effective treatment for CRP, particularly for patients with deep ulcers. Adequately randomized controlled trials are required to confirm the results of the present study.

Abstract
The effects of hyperbaric oxygen (HBO) on mouse skin two-stage chemical carcinogenesis were examined. Six-week-old inbred CD-1 female mice were divided into the following five groups: group 1, normoxia and application of 25 nmol 7,12-dimethylbenz[a]anthracene (DMBA) and 8.5 nmol 12-O-tetradecanoylphorbol-13-acetate (TPA) (n=19); group 2, HBO and DMBA/TPA (n=21); group 3, HBO and DMBA/acetone (n=3); group 4, normoxia and acetone (n=3); and group 5, non-treatment group (n=5). HBO was started at the same time as DMBA. Mice were euthanized at 23 weeks after the start of the experiment. Mice in group 2 showed the occurrence of tumors at 8 weeks after the beginning of the experiment, while the occurrence of tumors in mice in group 1 was observed beginning at 9 weeks. There was a difference in occurrence among low-grade papillomas, high-grade papillomas and SCCs in both groups 1 and 2 by the χ (2)-test at end of the experiment (p<0.05). The Ki-67 labeling indices of tumors revealed that the percentages of positive cells in low-grade papillomas in groups 1 and 2 were 15.27 ± 2.54% and 29.67 ± 2.82%, respectively (p<0.01). The results suggested that the tumors in group 2, which was treated with HBO, were more progressive than those in group 1, which was not treated with HBO. In this study, HBO accelerated tumor cell proliferation and advanced tumor progression in skin carcinogenesis by DMBA/TPA.

Abstract
PURPOSE The purpose of this paper was to provide an evidence-based evaluation of the safety and effectiveness of hyperbaric oxygen therapy (HBOT) for the treatment of non-neurological soft tissue radiation-related injuries (STRI). METHODS Systematic searches of medical bibliographic databases, the Internet, and lists of references were conducted in December 2010 and April 2013 to identify relevant primary studies. Inclusion and classification of papers was resolved through the application of a predetermined protocol. Information on both the safety and effectiveness of HBOT was analyzed. RESULTS Forty-one articles were included, with 11 comparing HBOT to a regimen without HBOT. Comparative evidence varied considerably in methodological quality, and numerous limitations were identified. Absolute data showed that serious adverse events after HBOT were rare, while more common adverse events were minor and self-limiting. Compared to observation, conventional, or sham therapies, evidence of benefit in clinical outcomes was shown for HBOT for radiation proctitis and wounds in irradiated soft tissue of the head and neck, but not for postirradiation soft tissue edema or radiation cystitis. Clinical outcomes differed little between HBOT and argon plasma coagulation for radiation proctitis and between HBOT and hyaluronic acid for radiation cystitis. CONCLUSIONS HBOT is a safe intervention which may offer clinical benefits to patients suffering from radiation proctitis and non-neurological STRI of the head and neck. However, differing clinical responses across STRI demonstrate a need for further well-designed clinical trials to validate the use of HBOT for individual STRI, both as an adjunct to conventional treatments and relative to definitive treatments.

Abstract
Psoriasis is a chronic inflammatory skin disease resulting from immune dysregulation. Regulatory T cells (Tregs) are important in the prevention of psoriasis. Traditionally, reactive oxygen species (ROS) are known to be implicated in the progression of inflammatory diseases, including psoriasis, but many recent studies suggested the protective role of ROS in immune-mediated diseases. In particular, severe cases of psoriasis vulgaris have been reported to be successfully treated by hyperbaric oxygen therapy (HBOT), which raises tissue level of ROS. Also it was reported that Treg function was closely associated with ROS level. However, it has been only investigated in lowered levels of ROS so far. Thus, in this study, to clarify the relationship between ROS level and Treg function, as well as their role in the pathogenesis of psoriasis, we investigated imiquimod-induced psoriatic dermatitis (PD) in association with Treg function both in elevated and lowered levels of ROS by using knockout mice, such as glutathione peroxidase-1−/− and neutrophil cytosolic factor-1−/− mice, as well as by using HBOT or chemicals, such as 2,3-dimethoxy-1,4-naphthoquinone and N-acetylcysteine. The results consistently showed Tregs were hyperfunctional in elevated levels of ROS, whereas hypofunctional in lowered levels of ROS. In addition, imiquimod-induced PD was attenuated in elevated levels of ROS, whereas aggravated in lowered levels of ROS. For the molecular mechanism that may link ROS level and Treg function, we investigated the expression of an immunoregulatory enzyme, indoleamine 2,3-dioxygenase (IDO) which is induced by ROS, in PD lesions. Taken together, it was implied that appropriately elevated levels of ROS might prevent psoriasis through enhancing IDO expression and Treg function.

Abstract
BACKGROUND Acute radiation proctitis is a common complication of pelvic radiation and management of acute radiation proctitis is under evaluation. The beneficial effects of ozonated olive oil (OzOO) have already been shown in the treatment of chronic wounds. Thus, this study was designed to evaluate the therapeutic effects of topical OzOO on acute radiation proctitis. AIMS To evaluate the therapeutic effects of topical OzOO on acute radiation proctitis. STUDY DESIGN Animal experimentation. METHODS RATS WERE DIVIDED INTO THREE GROUPS: control; irradiation+saline (1 mL); and irradiation +OzOO (1 mL). A single fraction of 17.5 Gy was delivered to each rat. The OzOO was administered rectally each day after irradiation. Each rat was observed daily for signs of proctitis. Irradiated rats were euthanised on days 5 and 10. The mucosal changes were evaluated macroscopically and pathologically. RESULTS According to the clinical findings, five rats in the irradiation+saline group showed Grade 4 symptoms on the 10(th) day. Macroscopic finding scores on the 10(th) day in the irradiation+saline and irradiation+OzOO groups were statistically significantly different. On pathological examination, radiation-induced mucosal damage was the most prominent 10 days after irradiation in saline-treated rats. On the 10(th) day, the irradiation+OzOO group showed mild inflammation and slight crypt change, which corresponded to Grade 1 pathological findings. CONCLUSION OzOO attenuates macroscopic and pathological findings of acute radiation proctitis in rats.
