Silicone Shell Breast Implants in Patients Undergoing Risk-Reducing Mastectomy With a History of Breast-Conserving Surgery and Adjuvant Radiotherapy: A Long-term Study.

BACKGROUND: Indications for breast-conserving surgery and adjuvant radiotherapy (BCSAR) in patients with breast carcinoma are increasing, as are indications for risk-reducing mastectomy (RRM) in healthy subjects. Most of these cases are reconstructed with silicone shell breast implants (SSBIs). OBJECTIVES: The aim of this work was to study complications of SSBIs in breast reconstruction in patients undergoing RRM with previous BCSAR. METHODS: A prospective cohort study was designed. The study group included cases of RRM reconstructed with SSBI in patients who had previously undergone BCSAR in the same breast. The control group consisted of patients with high-risk breast cancer who had undergone RRM and immediate SSBI reconstruction without previous BCSAR. RESULTS: There was a history of BCSAR in 15.8% of cases. The first SSBI used in immediate reconstruction after RRM was replaced in 51.5% of cases with a mean [standard deviation] survival of 24.04 [28.48] months. BCSAR was significantly associated with pathological capsular contracture (P = .00) with this first SSBI (37.5% vs 5.9%). Of the cases requiring the replacement of the first SSBI, 44.23% suffered failure of the second SSBI, with a mean survival of 27.95 [26.53] months. No significant association was found between the consecutive development of capsular contracture in the second SSBI and a previous history of BCSAR (P = .10). CONCLUSIONS: BCSAR prior to RRM reconstructed with an SSBI is associated with a significant increase in pathological capsular contracture. Patients should be warned of the high rate of SSBI complications and reconstruction failure. Polyurethane-coated implants may provide an alternative in cases in which alloplastic reconstruction is considered in patients with previous BCSAR.

A Pilot Study of Nutritional Supplementation in Soft Tissue Sarcoma Patients.

Background: Wound healing is particularly important for sarcoma patients who undergo neoadjuvant radiation therapy. Previous studies have demonstrated wound complications in this population approaching 35%. With this high rate of wound healing issues, identifying treatment modalities to minimize these complications is of paramount importance. Methods: All patients with high grade bone and soft tissue sarcoma received 15 days of twice daily amino acid supplementation starting in the immediate post-operative period. We documented the healing status of the surgical wound, the primary outcome, at all follow up appointments until six months after surgery. Non-healing wounds were defined as any wound requiring 1) a return visit to the OR for debridement, 2) IV antibiotics (ABX), and 3) unhealed wounds at 6 months post-operatively.1 For each patient, we collected biometrics with lean body mass analysis at preoperative appointment, and two and six weeks postoperatively. The proportion with non-healing wounds was compared with a historical patient cohort using the chi-square test. In a subgroup of participants with body composition measurements, we also compared changes in mean fat mass, lean mass, and psoas index from pre-operative baseline to 6 months post-operative using generalized linear models. Results: A total of 33 consecutive patients were supplemented with a branched chain amino acid (BCAA) formulation. The historical cohort included 146 participants from the previous 7 years (2010-2017). 26% of patients in the historical cohort experienced wound complications compared to 30% in the supplemented group. (p=0.72) When focusing specifically on lower extremity sarcomas treated with neoadjuvant radiation therapy, 46% of patients in the supplemented group experienced wound healing complications compared to 39% in the non-supplemented group (p=0.68). BCAA supplementation was found to be protective with regards to decreasing muscle wasting with no difference in psoas index measurements throughout the study period compared to a 20% muscle loss in the historical cohort (p=0.02). Conclusion: In our limited sample size, there was no difference in wound healing complications between sarcoma patients who received postoperative BCAA supplementation compared to a historical cohort who were not supplemented. Patients who did not receive supplementation had a significant decline in post-operative psoas index following operative sarcoma removal. Level of Evidence: III.

Acute skin toxicity of conventional fractionated versus hypofractionated radiotherapy in breast cancer patients receiving regional node irradiation: the real-life prospective multicenter HYPOBREAST cohort.

BACKGROUND: Large-scale trials have shown that hypofractionated adjuvant breast radiotherapy was as effective in terms of survival and local control as conventional fractionated radiotherapy, and acute toxicity was reduced with hypofractionated radiotherapy. However, there is a lack of data about the toxicity of breast with regional nodal irradiation (RNI). The aim of this study was to assess the effect of fractionation on radiation-related acute skin toxicity in patients receiving RNI in addition to whole-breast or chest wall irradiation, using real-life data. METHODS: We conducted a prospective, multicenter cohort study with systematic computerized data collection integrated into Mosaiq®. Three comprehensive cancer centers used a standardized form to prospectively collect patient characteristics, treatment characteristics and toxicity. RESULTS: Between November 2016 and January 2022, 1727 patients were assessed; 1419 (82.2%) and 308 (17.8%) patients respectively received conventional fractionated and hypofractionated radiation therapy. Overall, the incidence of acute grade 2 or higher dermatitis was 28.4% (490 patients). Incidence was lower with hypofractionated than with conventional fractioned radiation therapy (odds ratio (OR) 0.34 [0.29;0.41]). Two prognostic factors were found to increase the risk of acute dermatitis, namely 3D (vs IMRT) and breast irradiation (vs chest wall). CONCLUSION: Using real-life data from unselected patients with regional nodal irradiation, our findings confirm the decreased risk of dermatitis previously reported with hypofractionated radiation therapy in clinical trials. Expansion of systematic data collection systems to include additional centers as well as dosimetric data is warranted to further evaluate the short- and long-term effects of fractionation in real life.

Automated coronary artery calcium scoring in patients with breast cancer to assess the risk of heart disease following adjuvant radiation therapy.

AIM: Validation of coronary artery calcium (CAC) scores as prognostic factors of acute coronary events (ACE) development in breast cancer patients are demanded. We investigated prognostic impact of CAC on ACE development with cardiac exposure to radiation. METHODS: We evaluated breast cancer patients with (n = 511) or without (n = 600) adjuvant radiotherapy (RT) between 2005 and 2013. CAC Agatston scores were analyzed using a deep-learning-based algorithm. Individual mean heart dose (MHD) was calculated, and no RT was categorized as 0 Gy. The primary endpoint was the development of ACE following breast surgery. RESULTS: In the RT and no-RT cohorts, 11.2% and 3.7% exhibited CAC >0, respectively. Over a 9.3-year follow-up period, the 10-year ACE rate was 0.7%. In the multivariate analysis, the CAC score was a significant risk factor for ACE (CAC >0 vs CAC = 0, 10-year 6.2% vs 0.2%, P < 0.001). In the subgroup with CAC >0, the 10-year ACE rates were 0%, 3.7%, and 13.7% for patients receiving mean heart doses of 0 Gy, 0-3 Gy, and >3 Gy, respectively (P = 0.133). Although CAC score was not predictive for non-ACE heart disease risk (P > 0.05), the 10-year non-ACE heart disease rates were 1.7%, 5.7%, and 7.1% for patients with CAC = 0 receiving MHD of 0 Gy, 0-3 Gy, and >3 Gy, respectively (P < 0.001). CONCLUSIONS: The CAC score was a significant predictor of ACE in patients with breast cancer. Although further studies are required, CAC score screening on simulation CT in patients undergoing breast RT can help identify those with high risk for ACE on a per-patient basis.

Dietary Antioxidant Capacity Promotes a Protective Effect against Exacerbated Oxidative Stress in Women Undergoing Adjuvant Treatment for Breast Cancer in a Prospective Study.

Breast cancer (Bca) is the most common type of cancer among women worldwide, and oxidative stress caused by adjuvant treatment may be decreased by antioxidant intake. The aim of this study is to investigate the associations between Dietary antioxidant Capacity (DaC) and oxidation and antioxidant biomarkers in women undergoing adjuvant treatment (AT) for Bca. This prospective study had a sample of 70 women (52.2 ± 10.7 y). DaC (mmol/g) was calculated using nutritional data obtained from a Food Frequency Questionnaire, and blood was collected to measure the oxidation and antioxidant biomarkers at baseline (T0), and after AT (T1). Carbonylated protein levels were inversely associated with DaC at T1 (p = 0.004); women showed an increased risk of having increment on lipid hydroperoxides and thiobarbituric acid reactive substances (TBARS), and decrement on ferric reducing antioxidant power (FRAP) and reduced glutathione after AT, in response to lowered DaC (p < 0.05). Carbonylated proteins, TBARS and FRAP levels remained stable between the periods for women at the 3rd DaC tertile at T1, differentiating them from those at the 1st tertile, who showed negative changes in these biomarkers (p < 0.04). DaC may be beneficial for women undergoing AT for Bca, since it promoted a reduction in oxidative stress.

Emotional Problems Prior to Adjuvant Radiation Therapy for Breast Cancer.

BACKGROUND/AIM: Being scheduled for radiotherapy can cause emotional distress. This study aimed to identify risk factors in 338 patients assigned to radiotherapy for breast cancer. PATIENTS AND METHODS: Nineteen potential risk factors including the COVID-19 pandemic were investigated for associations with the six emotional problems included in the National Comprehensive Cancer Network Distress Thermometer. RESULTS: Worry and fears were significantly associated with age ≤60 years; sadness with age and Karnofsky performance score (KPS) <90; depression with KPS and Charlson Comorbidity Index ≥3; loss of interest with KPS. Trends were found for associations between sadness and additional breast cancer/DCIS, Charlson Index and chemotherapy; between depression and additional breast cancer/DCIS, treatment volume and nodal stage N1-3; between nervousness and additional breast cancer/DCIS, mastectomy and triple-negativity; between loss of interest and Charlson Index, family history of breast cancer/DCIS, invasive cancer, chemotherapy, and treatment volume. The COVID-19 pandemic did not increase emotional problems. CONCLUSION: Several risk factors for emotional problems were identified. Patients with such factors should receive psychological support well before radiotherapy.

Why Concurrent CDDP and Radiotherapy Has Synergistic Antitumor Effects: A Review of In Vitro Experimental and Clinical-Based Studies.

Chemo-radiotherapy, which combines chemotherapy with radiotherapy, has been clinically practiced since the 1970s, and various anticancer drugs have been shown to have a synergistic effect when used in combination with radiotherapy. In particular, cisplatin (CDDP), which is often the cornerstone of multi-drug combination cancer therapies, is highly versatile and frequently used in combination with radiotherapy for the treatment of many cancers. Therefore, the mechanisms underlying the synergistic effect of CDDP and radiotherapy have been widely investigated, although no definitive conclusions have been reached. We present a review of the combined use of CDDP and radiotherapy, including the latest findings, and propose a mechanism that could explain their synergistic effects. Our hypothesis involves the concepts of overlap and complementation. "Overlap" refers to the overlapping reactions of CDDP and radiation-induced excessive oxidative loading, which lead to accumulating damage to cell components, mostly within the cytoplasm. "Complementation" refers to the complementary functions of CDDP and radiation that lead to DNA damage, primarily in the nucleus. In fact, the two concepts are inseparable, but conceptualizing them separately will help us understand the mechanism underlying the synergism between radiation therapy and other anticancer drugs, and help us to design future radiosensitizers.

Adjuvant radiotherapy and radioiodine treatment for locally advanced differentiated thyroid cancer: systematic review and meta-analysis.

BACKGROUND: Treatment for locally advanced differentiated thyroid cancer is surgery followed by radioiodine while the role of adjuvant external beam radiotherapy (EBRT) is debated. METHODS: The panel of the Italian Association of Radiotherapy and Clinical Oncology developed a clinical recommendation on the addition of EBRT to radioiodine after surgery for locally advanced differentiated thyroid cancer by using the Grades of Recommendation, Assessment, Development, and Evaluation methodology and the Evidence to Decision framework. A systematic review with meta-analysis about this topic was conducted with a focus on outcome of benefits and toxicity. RESULTS: Locoregional control was improved by EBRT while no considerable toxicity impact was reported. CONCLUSION: The panel judged uncertain the benefit/harms balance; final recommendation was conditional both for EBRT + radioiodine and radioiodine alone in the adjuvant setting.

Angiotensin-Converting Enzyme Inhibitor Reduces Radiation-Induced Periprosthetic Capsular Fibrosis.

BACKGROUND: The capsular contracture is one of the main complications after radiotherapy in patients with implant-based reconstruction. The aim of this study is to evaluate the efficacy of ramipril for the prevention of radiation-induced fibrosis around the silicone implant. MATERIALS AND METHODS: Thirty Wistar rats in 5 groups were used. Group 1: implant; group 2: implant + radiation; group 3: ramipril + implant; group 4: ramipril + implant + radiation; group 5: sham. Ramipril treatment was started 5 d before surgery and continued for 12 wk after surgery. A mini silicone implant was placed in the back of the rats. A single fraction of 21.5 Gy radiation was applied. Tissues were examined histologically and immunohistochemically (TGF-ß1, MMP-2, and TIMP-2 expression). The alteration of plasma TGF-ß1 levels was examined before and after the experiment. RESULTS: After applying implant or implant + radiation, capsular thickness, percentage of fibrotic area, tissue and plasma TGF-ß1 levels significantly increased, and MMP-2/TIMP-2 ratio significantly decreased compared with the sham group. In ramipril-treated groups, the decrease in capsular thickness, fibrosis, TGF-ß1 positivity, and an increase in MMP-2/TIMP-2 ratio were found significant. In the ramipril + implant + radiation group, the alteration values of TGF-ß1 dramatically decreased. CONCLUSIONS: Our results show that ramipril reduces radiation-induced fibrosis and contracture. The results of our study may be important for the design of the clinical trials required to investigate the effective and safe doses of ramipril, which is an inexpensive and easily tolerated drug, on humans.

An easy way to determine bone mineral density and predict pelvic insufficiency fractures in patients treated with radiotherapy for cervical cancer.

PURPOSE: The aim of this study was to investigate whether bone mineral density (BMD) as measured in planning computed tomographies (CTs) by a new method is a risk factor for pelvic insufficiency fractures (PIF) after radio(chemo)therapy (R(C)T) for cervical cancer. METHODS: 62 patients with cervical cancer who received definitive or adjuvant radio(chemo)therapy between 2013 and 2017 were reviewed. The PIF were detected on follow-up magntic resonance imaging (MRI). The MRI of the PIF patients was registered to the planning CT and the PIF contoured. On the contralateral side of the fracture, a mirrored structure of the fracture was generated (mPIF). For the whole sacral bone, three lumbar vertebrae, the first and second sacral vertebrae, and the PIF, we analyzed the BMD (mg/cm3), V50Gy, Dmean, and Dmax. RESULTS: Out of 62 patients, 6 (9.7%) had a fracture. Two out of the 6 patients had a bilateral fracture with only one of them being symptomatic. PIF patients showed a significantly lower BMD in the sacral and the lumbar vertebrae (p < 0.05). The BMD of the contoured PIF, however, when comparing to the mPIF, did not reach significance (p < 0.49). The difference of the V50Gy of the sacrum in the PIF group compared to the other (OTH) patients, i.e. those without PIF, did not reach significance. CONCLUSION: The dose does not seem to have a relevant impact on the incidence of PIF in our patients. One of the predisposing factors for developing PIF after radiotherapy seems to be the low BMD. We presented an easy method to assess the BMD in planning CTs.

Bone health and osteoporosis screening in gynecologic cancer survivors.

Cancer treatment-induced bone loss is a known side effect of cancer therapy that increases the risk of osteoporosis and bone fracture. Women with gynecologic cancer are at increased risk of bone loss secondary to the combined effect of oophorectomy and adjuvant therapies. Data regarding bone loss in women with gynecologic cancers are overall lacking compared to other cancer populations. Consequently, guidelines for osteoporosis screening in women with cancer are largely based on data generated among non-gynecologic cancer survivors. This article reviews current available data of bone health in women with gynecologic cancer, summarizes best-available guidelines for screening for osteoporosis in women with cancer, and provides guidance for osteoporosis screening in women with gynecologic cancers based on best available evidence.

Design of the PROstate cancer follow-up care in Secondary and Primary hEalth Care study (PROSPEC): a randomized controlled trial to evaluate the effectiveness of primary care-based follow-up of localized prostate cancer survivors.

BACKGROUND: In its 2006 report, From cancer patient to cancer survivor: lost in transition, the U.S. Institute of Medicine raised the need for a more coordinated and comprehensive care model for cancer survivors. Given the ever increasing number of cancer survivors, in general, and prostate cancer survivors, in particular, there is a need for a more sustainable model of follow-up care. Currently, patients who have completed primary treatment for localized prostate cancer are often included in a specialist-based follow-up care program. General practitioners already play a key role in providing continuous and comprehensive health care. Studies in breast and colorectal cancer suggest that general practitioners could also consider to provide survivorship care in prostate cancer. However, empirical data are needed to determine whether follow-up care of localized prostate cancer survivors by the general practitioner is a feasible alternative. METHODS: This multicenter, randomized, non-inferiority study will compare specialist-based (usual care) versus general practitioner-based (intervention) follow-up care of prostate cancer survivors who have completed primary treatment (prostatectomy or radiotherapy) for localized prostate cancer. Patients are being recruited from hospitals in the Netherlands, and randomly (1:1) allocated to specialist-based (N = 195) or general practitioner-based (N = 195) follow-up care. This trial will evaluate the effectiveness of primary care-based follow-up, in comparison to usual care, in terms of adherence to the prostate cancer surveillance guideline for the timing and frequency of prostate-specific antigen assessments, the time from a biochemical recurrence to retreatment decision-making, the management of treatment-related side effects, health-related quality of life, prostate cancer-related anxiety, continuity of care, and cost-effectiveness. The outcome measures will be assessed at randomization (≤6 months after treatment), and 12, 18, and 24 months after treatment. DISCUSSION: This multicenter, prospective, randomized study will provide empirical evidence regarding the (cost-) effectiveness of specialist-based follow-up care compared to general practitioner-based follow-up care for localized prostate cancer survivors. TRIAL REGISTRATION: Netherlands Trial Registry, Trial NL7068 (NTR7266). Prospectively registered on 11 June 2018.

Randomised comparison of 1.1 GBq and 3.7 GBq radioiodine to ablate the thyroid in the treatment of low-risk thyroid cancer: a 13-year follow-up.

Purpose: The optimal activity of radioiodine (I-131) administered for ablation therapy in papillary and follicular thyroid cancer after thyroidectomy remains unknown in a long-term (> 10 year) follow-up. Some, shorter follow-up studies suggest that activities 1.1 GBq and 3.7 GBq are equally effective. We evaluated the long-term outcomes after radioiodine treatment to extend current knowledge about the optimal ablative dose of I-131.Methods: One hundred and sixty consecutive adult patients (129 females, 31 males; mean age 46 ± 14 y, range 18-89 y) diagnosed with histologically confirmed differentiated thyroid cancer, were randomised in a prospective, phase III, open-label, single-centre study, to receive either 1.1 GBq or 3.7 GBq of I-131 after thyroidectomy. At randomisation, patients were stratified according to the histologically verified cervical lymph node status and were prepared for ablation using thyroid hormone withdrawal. No uptake in the whole-body scan with I-131 and serum thyroglobulin concentration less than 1 ng/mL at 4-8 months after treatment was considered successful ablation.Results: Median follow-up time was 13.0 years (mean 11.0 ± 4.8 y; range 0.3-17.1 y). Altogether 81 patients received 1.1 GBq with successful ablation in 45 (56%) patients. In the original study, thirty-six patients (44%) needed one or more extra administrations to replete the ablation. Of these, 4 (8.9%) and 5 (14%) patients relapsed during the follow-up, respectively. Of the 79 patients treated with 3.7 GBq 45 (57%) had successful ablation after one administration of radioiodine and 34 (43%) needed several treatments. Of these, 2 (4.4%) and 9 (26.5%) patients relapsed, respectively. The groups did not differ in the proportion of patients relapsing (p = .591).Conclusion: During follow-up of median 13 years, 3.7 GBq is not superior to 1.1 GBq in the radioiodine treatment after thyroidectomy in papillary and follicular thyroid cancer.

Lumbar vertebral osteoradionecrosis: a rare case report with 10-year follow-up and brief literature review.

BACKGROUND: Osteoradionecrosis (ORN) is a complication that occurs after radiotherapy for head or neck malignancies. ORN of the spine is rare, with only few cases affecting the cervical spine reported to date. To our knowledge, no case of lumbar ORN has been reported. We report a rare case of ORN in the lumbar spine that occurred 2 years after radiotherapy and perform a literature review. CASE PRESENTATION: We present a case of lumbar ORN that occurred 2 years after radiotherapy for gallbladder carcinoma. The patient was successfully treated conservatively and followed up for > 10 years. CONCLUSIONS: ORN of the spine is a rare complication of radiotherapy. Spinal ORN is clinically described as a chronic disease with a slow onset. The most common presenting symptom of spinal ORN is pain. However, as ORN progresses, spinal kyphosis and instability can lead to neurological compression and thus to induced myelopathy or radiculopathy. Treatment of spinal ORN is comprehensive, including orthosis, medication, hyperbaric oxygen therapy, surgery, and new treatment combinations of pentoxifylline and tocopherol. The surgical rate for spinal ORN is relatively high.

Genetic Variability of Antioxidative Mechanisms and Cardiotoxicity after Adjuvant Radiotherapy in HER2-Positive Breast Cancer Patients.

BACKGROUND: Breast cancer treatment is associated with the occurrence of various cardiac adverse events. One of the mechanisms associated with cardiotoxicity is oxidative stress, against which cells are protected by antioxidative enzymes. Genetic variability of antioxidative enzymes can affect enzyme activity or expression, which modifies the ability of cells to defend themselves against oxidative stress and could consequently contribute to the occurrence of treatment-related cardiotoxicity. Our aim was to evaluate the association of common polymorphisms in antioxidative genes with cardiotoxicity after adjuvant radiotherapy (RT) in HER2-positive breast cancer patients. METHODS: Our retrospective study included 101 HER2-positive early breast cancer patients who received trastuzumab and adjuvant RT. We isolated DNA from buccal swabs and used competitive allele-specific PCR for genotyping of PON1 rs854560 and rs662, GSTP1 rs1138272 and rs1695, SOD2 rs4880, CAT rs1001179, and HIF1 rs1154965 polymorphisms. N-terminal pro B-type natriuretic peptide (NT-proBNP), left ventricular ejection fraction, and NYHA class were used as markers of cardiotoxicity. We used logistic regression to evaluate the association of genetic factors with markers of cardiotoxicity. RESULTS: Carriers of at least one polymorphic PON1 rs854560 allele were less likely to have increased NT-proBNP (OR = 0.34; 95% CI = 0.15-0.79; P = 0.012), even after adjustment for age (OR = 0.35; 95% CI = 0.15-0.83; P = 0.017). Carriers of at least one polymorphic PON1 rs662 allele were more likely to have increased NT-proBNP (OR = 4.44; 95% CI = 1.85-10.66; P = 0.001), even after adjustment for age (OR = 5.41; 95% CI = 2.12-13.78; P < 0.001). GSTP1 rs1695 was also associated with decreased NT-proBNP in the multivariable analysis (P = 0.026), while CAT rs1001179 was associated with NYHA class in the univariable (P = 0.012) and multivariable analysis (P = 0.023). CONCLUSION: In our study, polymorphisms PON1 rs662 and rs854560, CAT rs1001179, and GSTP1 rs1695 were significantly associated with the occurrence of cardiac adverse events after adjuvant RT and could serve as biomarkers contributing to treatment personalization.

Associations of telomerase reverse transcriptase rs10069690 and rs2736100 polymorphisms with papillary thyroid carcinoma.

Papillary thyroid carcinoma is one of the most common endocrine malignancies. Telomerase reverse transcriptase rs10069690 and rs2736100 polymorphisms have been studied in thyroid carcinomas with different ethnicity, but the results were inconsistent. Therefore, we evaluated the relationship between rs10069690 and rs2736100 polymorphisms and papillary thyroid carcinoma risk and furtherly investigated the associations of these polymorphisms with stimulated thyroglobulin (sTg) positivity and adverse reactions of I treatment in papillary thyroid carcinoma. Four hundred thirty-six papillary thyroid carcinoma patients and 345 controls of Chinese Han population were included in our study. Rs10069690 and rs2736100 were genotyped using improved multiple ligase detection reactions. Analysis of inheritance model was performed using the unconditional logistic regression. In our study, rs10069690 and rs2736100 were associated with papillary thyroid carcinoma risk, especially in females over 45 years of age (P = 0.002 and P = 0.032, respectively). Rs10069690 was associated with sTg positivity and with an rs10069690-related occurrence risk order of thyroglobulin antibody (Tg-Ab)(+) + Tg(+) > Tg-Ab(+) + sTg(-) > Tg-Ab(-) + sTg(+). Patients with the homozygous TT genotype of rs10069690 had an increased risk of neck discomfort (P = 0.033), while the homozygous CC genotype of rs2736100 had a decreased risk of gastrointestinal toxicity (P = 0.048). Our data demonstrated that rs10069690 and rs2736100 might be bio-indicators related to papillary thyroid carcinoma risk in females over 45 years of age and I treatment-related toxicity. In addition, rs10069690 may be a predictor of bad clinicopathological features and poor prognosis from a serological point of view.

Mepitel Film and Mepilex Lite for the prophylaxis and treatment of skin toxicities from breast radiation.

Despite the prevalence of radiation dermatitis in breast cancer patients, current practice guidelines for its treatment are limited. We aimed to discuss the quality of evidence for the barrier-forming Mepitel Film for prophylaxis of radiation dermatitis, and argue for further investigation into evidence-based management of skin toxicities. Two studies assessing Mepitel Film were critically evaluated. Both reported that Mepitel Film decreased radiation dermatitis; moreover, patient-reported outcomes significantly favoured Mepitel Film. However, there has not been global adoption of barrier-forming films such as Mepitel, in part due to the absence of multi-centred randomised trials and the heterogeneity of study designs.

Return to work after breast cancer: The role of treatment-related side effects and potential impact on quality of life.

For breast cancer survivors return to work (RTW) is important from an economic, societal and personal perspective. Thus, we investigated the impact of side effects and other factors on RTW. Five years post-diagnosis 135 disease-free breast cancer survivors below retirement age who were employed pre-diagnosis recorded their current and previous working status and reasons for impaired RTW. Patient-reported outcomes were prospectively reported over the cancer continuum. One year post-surgery 57% of survivors worked the same and 22% with reduced working time compared to pre-diagnosis. Logistic regression revealed significant associations of depressive symptoms, arm morbidity, lower education and younger age with impaired RTW after 1 year, and persisting physical fatigue and living with partner with impaired RTW after 5 years. Major self-reported reasons included fatigue and cognitive problems. Temporal patterns of general quality of life (QoL), physical, cognitive and role function, and financial problems were significantly worse among women with no RTW compared to those working again. In conclusion, cessation of work after breast cancer seems associated with worse QoL. Fatigue, psychological and cognitive problems as well as arm morbidity seemed to hinder RTW. Thus, a better management of these problems might help women to stay in working life.
