Abstract
INTRODUCTION Surface-guided radiation therapy (SGRT) has emerged as a powerful tool to improve patient setup accuracy in radiation therapy (RT). Combined with the goal of increasing RT accuracy is an ongoing effort to decrease RT side effects. The application of a prophylactic skin dressing to the treatment site is a well-documented method of reducing skin-related side effects from RT. This paper aims to investigate whether the application of Mepitel, a prophylactic skin dressing, has an impact on the accuracy of surface-guided patient setups in chest wall RT. METHODS A retrospective analysis of daily image-guided Online Corrections (OLCs) from patients undergoing chest wall irradiation with SGRT was performed. Translational (superior-inferior, lateral, and anterior-posterior) OLC magnitude and direction were compared between patients treated with Mepitel applied and those treated without. Systematic and random errors were calculated and compared between groups. RESULTS OLCs from 275 fractions were analysed. Mean OLCs were larger for patients with Mepitel applied in the superior_inferior axis (0.34 vs. 0.22 cm, P = 0.049) and for the combined translational vector (0.54 vs. 0.43 cm, P = 0.043). Combined translational systematic error was slightly larger for patients with Mepitel applied (0.15 vs. 0.09 cm). CONCLUSION Mepitel can impact the accuracy of SGRT patient-positioning in chest wall RT. The variation however is small and unlikely to have any clinical impact if SGRT is coupled with image guidance and appropriate PTV margins. Further investigation is required to assess the effect of Mepitel on SGRT accuracy in other treatment sites, as well as any potential dosimetric impacts.

Adv Radiat Oncol 2024; 9:101318. [PMID: 38260224 PMCID: PMC10801659 DOI: 10.1016/j.adro.2023.101318] [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: 03/26/2023] [Accepted: 07/13/2023] [Indexed: 01/24/2024] Open
Abstract
Purpose Moist desquamation (MD) is a concerning acute side effect of radiation therapy for breast cancer, often seen in skin folds for patients having large or pendulous breasts. In vivo skin dosimetry, clinical assessments, and patient-reported skin reactions were used to determine a relationship between dose-area metrics and the development of MD, to lend insight into skin tolerances and possibly guide future treatment planning dose constraints. Methods and Materials Skin dose was measured using GafChromic film on the inner surface of an early prototype carbon-fiber accessory for breast support to remove the inframammary fold in 20 patients at high risk of developing MD undergoing adjuvant whole breast radiation therapy. Prescribed doses were 42.5 Gray (Gy) in 16 fractions or 50 Gy in 25 fractions using 6 to 15 MV x-rays. To account for fraction size differences, analysis was performed using the equivalent dose in 2 Gy fractions using α/β = 11 (EQD211). MD was assessed out to 2 weeks post radiation therapy by trained therapists and by a patient-reported outcome questionnaire. Results Statistically significant differences in areas receiving 30 to 48 Gy (EQD211) were observed between patients who did and did not develop MD in the inframammary area. Patients receiving EQD211 maximum dose ≤ 46 Gy and ≥ 38 Gy to ≤ 50 cm2 of their breast skin did not develop MD. Conclusions The findings of this study offer insight into the relationship between skin toxicity and areas of skin irradiated to doses up to 50 Gy. Potential skin dose constraints to test in future studies to prevent MD are suggested.

Abstract
Radiotherapy is an important modality for cancer treatment. About 50% of cancer patients receive radiotherapy, and one-third of radiotherapy recipients were identified as having unmet psychosocial needs. The unmet psychosocial needs worsen the patient's quality of life and treatment effectiveness. This review aims to identify the psychosocial needs of post-radiotherapy cancer survivors and their direct caregivers. Systematic research of Embase, Scopus and PubMed was done and 17 studies were selected for analysis. The results show that patients encounter distress and fear due to treatment immobilization and unfamiliarity with procedures respectively. Information provision is a common need raised by patients and caregivers. Patients and caregivers report relationship problems due to affected sexual functions. To facilitate future studies, solutions to each identified psychosocial need are proposed in the discussion based on the 17 selected papers and other supporting literature. This review proposes art therapy to alleviate psychological distress, and pre-treatment information sessions to reinforce information delivery. Creative interventions such as a sexual rehabilitation program are recommended. Future studies are warranted to examine the interventions and thus improve the patients' and caregivers' well-being.

Front Oncol 2023; 13:1156619.

Abstract
In selected patients, intraoperative radiotherapy (IORT) offers an alternative to standard external beam radiotherapy (EBRT) while providing equivalent breast cancer control outcomes. After IORT, most patients do not require external beam radiotherapy and thus avoid the need to travel to and from a radiotherapy centre in the weeks after surgery. EBRT is associated with an increased risk of non-breast cancer mortality and poorer cosmetic outcomes while increasing patient travel time, emissions associated with travel and time spent in the hospital. Consequently, EBRT is associated with an overall reduction in quality of life compared to IORT. Patients with other on-going health conditions or clinical impairments are likely to be affected by the daily radiotherapy requirement. Should these patients be consulted during their pre-operative assessment as to options to undergo IORT? This paper describes a case of IORT and follow up in a functionally blind patient. Quality of life effects are elucidated and further support the use of IORT in selected breast cancer patients with health conditions or impairments.

Hyperbaric oxygen therapy for local late radiation toxicity in breast cancer patients: A systematic review. Breast 2022; 67:46-54. [PMID: 36587606 PMCID: PMC9982272 DOI: 10.1016/j.breast.2022.12.009] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Revised: 12/15/2022] [Accepted: 12/19/2022] [Indexed: 12/24/2022] Open
Abstract
PURPOSE This systematic review aims to provide an overview of the literature on the effect of hyperbaric oxygen therapy (HBOT) on symptoms of local late radiation toxicity (LRT) in patients treated for breast cancer. METHODS A systematic search was performed in September 2021. All studies with a sample size of ≥10 patients reporting the effect of HBOT for symptoms of LRT after radiotherapy of the breast and/or chest wall were included. The ROBINS-I tool was used for critical appraisal of methodological quality. The toxicity outcomes pain, fibrosis, lymphedema, necrosis/skin problems, arm and shoulder mobility, and breast and arm symptoms were evaluated. RESULTS Nine studies concerning a total of 1308 patients were included in this review. Except for one study, sample sizes were small. Most studies had inadequate methodology with a substantial risk of bias. Post-HBOT, a significant reduction of pain was observed in 4/5 studies, of fibrosis in 1/2 studies, and of lymphedema of the breast and/or arm in 4/7 studies. Skin problems of the breast were significantly reduced in 1/2 studies, arm- and shoulder mobility significantly improved in 2/2 studies, and breast- and arm symptoms were significantly reduced in one study. CONCLUSION This systematic review indicates that HBOT might be useful for reducing symptoms of LRT in breast cancer patients, however evidence is limited. A randomized controlled trial in a larger cohort of patients including a combination of patient- and clinician-reported outcome measures would be valuable to assess the effect of HBOT on symptoms of LRT.

Abstract
BACKGROUND Breast cancer is currently the world's most predominant malignancy. In cancer progression, angiogenesis is a requirement for tumor growth and metastasis.Alpinumisoflavone (AIF), a bioactive isoflavonoid, exhibited good binding affinity with the angiogenesis pathway's druggable target through molecular docking. OBJECTIVES To confirm AIF's angiogenesis inhibitory activity, cytotoxic potential toward breast cancer cells, and druggability. METHODS Antiangiogenic activity was evaluated in six pro-angiogenic proteins in vitro, duck chorioallantoic membrane (CAM) in ovo, molecular docking and druggability in silico. RESULTS Findings showed that AIF significantly inhibited (p = < 0.001) the HER2(IC50 = 2.96 µM), VEGFR-2(IC50 = 4.80 µM), MMP-9(IC50 = 23.00 µM), FGFR4(IC50 = 57.65 µM), EGFR(IC50 = 92.06 µM) and RET(IC50 = > 200 µM) activity in vitro.AIF at 25 µM-200 µM significantly inhibited (p = < 0.001) the total number of branch points (IC50 = 14.25 μM) and mean length of tubule complexes (IC50 = 3.52 μM) of duck CAM comparable (p = > 0.001) with the positive control 200 µM celecoxib on both parameters.AIF inhibited the growth of the estrogen-receptor-positive (ER +) human breast cancer cells (MCF-7) by 44.92 ± 1.79% at 100 µM while presenting less toxicity to human dermal fibroblast neonatal (HDFn) normal cells.The positive control 100 µM doxorubicin showed 86.66 ± 0.93% and 92.97 ± 1.27% inhibition with MCF-7 (IC50 = 3.62 μM) and HDFn, (IC50 = 27.16 μM) respectively.In docking, AIF has the greatest in silico binding affinity on HER2 (-10.9 kcal/mol) among the key angiogenic molecules tested. In silico rat oral LD50 calculation indicates that AIF is moderate to slightly toxic at 146.4 mg/kg with 1.1 g/kg and 20.1 mg/kg upper and lower 95% confidence limits. Lastly, it sufficiently complies with Lipinski's, Veber's, Egan's, Ghose's, and Muegge's Rule, supporting its oral drug-like property. CONCLUSION This study revealed that AIF possesses characteristics of a phytoestrogen compound with significant binding affinity, inhibitory activity against pro-angiogenic proteins, and cytotoxic potential against ER + breast cancer cells.The acceptable and considerable safety and drug-likeness profiles of AIF are worthy of further confirmation in vivo and advanced pre-clinical studies so that AIF can be elevated as a promising molecule for breast cancer therapy.

Abstract
PURPOSE To explore and describe experiences of older patients with cancer throughout their radiotherapy treatment, from diagnosis until follow-up after treatment. METHODS Individual interviews were conducted to explore different phases of radiotherapy. Interviews were recorded and transcribed verbatim. Inductive content analysis was applied. Each interview was coded separately. Then to the codes were analyzed further, and an overall theme was developed. RESULTS Twelve older patients with cancer, (7 male, 5 female) aged ≥ 65 related their experiences from radiotherapy treatment. A main theme describes the essence of their experiences; Understanding "just enough". The theme comprises five main categories: Understandable, adapted information is crucial for trusting health services; Previous experiences influence patients' perception and understanding; Involvement of next of kin is crucial to patients' comprehension; Professional treatment decisions and well-organized treatment determines satisfaction and Experiences of cooperation and coordination of services affects dependability. CONCLUSIONS Findings from this study describe how understanding "just enough" - not too much nor too little - may assist older patients with cancer in participating in treatment decisions, preventing false beliefs, feeling reassured during treatment and in navigating the complex health care system. Next of kin are important assets for older patients with cancer in understanding "just enough". Cancer nurses may map comprehension of information, as well as reveal patients' previous experiences.

Abstract
Radiotherapy is used in the treatment for primary brain tumours. Radiotherapy causes acute and late toxicities where skin reactions are most common. The potential for misreporting of toxicity in specific cases may be significant. Oncologist-reported and patient-reported outcomes of skin reactions are crucial. A combination of PROs and oncologists’ assessments is most accurate.
Background Skin reaction is a common side-effect of radiotherapy and often only assessed as clinician-reported outcome (CRO). The aim was to examine and compare patient-reported outcome (PRO) of skin reactions with CRO for signs of acute skin reactions for patients with primary brain tumour receiving proton beam radiotherapy (PBT). A further aim was to explore patients’ experiences of the skin reactions. Methods Acute skin reactions were assessed one week after start of treatment, mid-treatment and end of treatment among 253 patients with primary brain tumour who underwent PBT. PRO skin reactions were assessed with the RSAS and CRO according to the RTOG scale. Fleiss’ kappa was performed to measure the inter-rater agreement of the assessments of skin reactions. Results The results showed a discrepancy between PRO and CRO acute skin reactions. Radiation dose was associated with increased skin reactions, but no correlations were seen for age, gender, education, occupation, other treatment or smoking. There was a poor agreement between patients and clinicians (κ = −0.016) one week after the start of PBT, poor (κ = −0.045) to (κ = 0.396) moderate agreement at mid treatment and poor (κ = −0.010) to (κ = 0.296) moderate agreement at end of treatment. Generally, patients’ symptom distress toward skin reactions was low at all time points. Conclusion The poor agreement between PRO and CRO shows that the patient needs to be involved in assessments of skin reactions for a more complete understanding of skin reactions due to PBT. This may also improve patient experience regarding involvement in their own care.

Abstract
The majority of patients receiving radiation therapy will experience a radiation skin reaction, ranging from mild erythema to severe moist desquamation. The anticipated skin reaction will vary by cancer diagnosis, dose of radiation, size of treatment field, and other treatment-and patient-related factors. Recently, research has dispelled long-held myths about avoiding skin care products prior to treatment, and the use of deodorant or antiperspirant during treatment for breast cancer and any potential for an increased skin dose with the use of skin care products. Patients no longer are restricted in using these products. Most of the research regarding skin reactions due to radiation has been conducted with women with breast cancer. No research has been found on the experience of a radiation skin reaction in patients with head and neck cancer (HNC), who often get the most severe skin reactions across all patient groups. Using the qualitative interpretive descriptive approach based on the methodological work by Thorne (1997), nine participants were interviewed about their experience of having a radiation skin reaction resulting from their treatment for HNC. Three themes emerged from the interviews, including 1) the symptom experience, 2) comparison to others, and 3) the experience of support and information. Implications include recommendations for practice and patient education.

Abstract
La majorité des patients recevant de la radiothérapie auront une réaction cutanée radio-induite allant d’un érythème léger à une desquamation humide étendue. Les réactions cutanées attendues varieront en fonction du diagnostic de cancer, de la dose et de la taille du champ d’irradiation ainsi que d’autres facteurs liés au traitement et au patient. Récemment, la recherche a dissipé les mythes longtemps entretenus sur les produits pour le soin de la peau qui auraient été à éviter avant le traitement, tout comme le déodorant et l’antisudorifique durant les traitements contre le cancer du sein (on craignait une surdose accrue pour la peau causée par l’utilisation de ces produits). Cette limitation a été levée. Or, la plupart des recherches sur les réactions cutanées radio-induites ont été menées auprès de femmes atteintes d’un cancer du sein; aucune n’a été trouvée sur les patients atteints de cancer de la tête et du cou, alors que de tous les groupes de patients, ce sont très souvent ceux-ci qui présentent les réactions cutanées les plus graves. Nous avons fait appel à la méthode descriptive interprétative qualitative basée sur le travail méthodologique de Thorne (1997) pour interroger neuf participants sur leurs réactions cutanées par suite de radiations pour leur cancer de la tête et du cou. Trois thèmes sont ressortis des entretiens : 1) l’expérience des symptômes; 2) la comparaison avec d’autres; 3) l’expérience du soutien et de l’information. Les implications comprennent des recommandations pour la pratique et l’éducation des patients.

Abstract
Fatigue in breast cancer patients undergoing radiotherapy has been studied less comprehensively than fatigue from chemotherapy. The aim of this study was to test the impact of psycho-social factors on the fatigue among breast cancer patients undergoing radiotherapy. This was a cross-sectional correlational study and participants were 210 breast cancer patients currently undergoing radiotherapy in an outpatient setting in Korea. Data collection was carried out from 22 July to 30 September 2019. The results of this study showed that symptom assessment, anxiety and depression, uncertainty, and perceived stress had a direct effect on the fatigue of breast cancer patients receiving radiotherapy, while social support had an indirect effect. These factors explained 67.2% of the fatigue among the participants. This study confirmed that various interventions for symptom assessment, anxiety and depression, uncertainty, and stress reduction need to be developed to reduce fatigue of breast cancer patients receiving radiotherapy. The present results form the basis for developing such interventions.

Abstract
In this study, an in-depth analysis of weight management experiences of breast cancer patients treated with tamoxifen is conducted, thereby providing basic data to help develop a multidimensional strategy to reduce recurrence and increase the survival rate of breast cancer patients. Study participants included nine breast cancer patients who were treated with tamoxifen at Kosin University Hospital and Saegyero Hospital in Busan Metropolitan City, Korea. This study employed the photovoice methodology. Participants described the need for family support and cooperation with weight management, provision of personalized weight management programs by medical institutions, provision of information on weight management programs by the community, and financial support for the weight management programs for breast cancer patients at the national level. This study emphasized the importance of weight management for breast cancer patients treated with tamoxifen and collected and analyzed vivid opinions of these patients using photos taken by them.

Abstract
PURPOSE Acute skin toxicity in the form of radiation dermatitis (RD) or skin hyperpigmentation (SH) is a common problem experienced by patients undergoing breast irradiation. Proton radiation has been thought to deliver higher doses to skin compared with photon radiation because of differences in the physical properties between photons and protons; however, limited literature exists directly comparing toxicity outcomes. METHODS AND MATERIALS The highest recorded grades of acute RD and SH were analyzed in 86 patients undergoing adjuvant radiation therapy to the breast with or without regional lymph nodes after lumpectomy (breast-conserving surgery) or mastectomy with either proton pencil-beam scanning (n = 39) or photon (n = 47) radiation therapy within a single institution to analyze differences in severity of acute skin reactions. For 34 of 47 photon and 33 of 39 proton patients, a "skin" contour was retroactively created in our treatment planning systems, and multiple dosimetric parameters were calculated to quantify objective radiation doses received by skin. RESULTS On χ2 analysis, the highest reported grade of RD was significantly higher in women undergoing proton radiation compared with photon radiation; grade ≥2 RD was present in 69.2% versus 29.8% of patients receiving proton and photon therapy, respectively (P = .002). Rates of grade 3 RD were 5.1% versus 4.3% for proton versus photon radiation, respectively (P = .848). Overall, there were no significant differences in rates of SH between modalities. There were no grade 4 to 5 toxicities in either cohort. CONCLUSIONS In a comparison with patients receiving photon radiation, a significantly higher rate of grade ≥2 RD was observed in patients undergoing proton radiation, with very low rates of grade 3 toxicity in both groups. Rates of SH did not differ significantly between modalities. Women should be counseled regarding the possibility of increased grade 2 toxicities, although this might present a dosimetric advantage for physicians when treating patients in the postmastectomy setting or when skin was involved on presentation.
