Abstract No consensus exists regarding the role of radiotherapy in the management of gynecologic cancer in nonagenarian patients. We retrospectively reviewed the outcomes of 19 consecutive nonagenarian patients with gynecologic cancer (6 endometrial cancers, 6 cervical cancers, 4 vulvar cancers, and 3 vaginal cancers) who were treated with radiotherapy. Radiotherapy was performed mainly in a palliative setting (n = 12; 63.2%), with a median dose of 45 Gy (range, 6–76 Gy). Infrequent major acute or late toxicities were reported. Among 19 patients, 9 (47.4%) experienced tumor progression, 5 (26.3%) experienced complete response, 2 (10.5%) experienced stable disease and/or partial response. At last follow-up, 12 patients (63.2%) had died; most deaths (n = 9) occurred because of the cancer. These results suggest that radiotherapy is feasible in the treatment of nonagenarian patients with gynecologic cancer.

The number of nonagenarian people in the world is steadily growing. This phenomenon will increase in future years: in 2050, world population prospects estimate 71.16 million people aged 90 years or older. The two main causes of death among people aged 85 years or more in Europe in 2003 were cardiovascular and cerebrovascular diseases and cancers. However, the elderly are often excluded from clinical trials; they are underrepresented in clinical registries and especially nonagenarians. Care (medical, surgical, oncology) of these very elderly is currently insufficiently based on scientific recommendations. For the physician, the choice to treat or not to treat very elderly patients (for fear of side effects) is difficult. Oncology is particularly affected by this problem. Here we review these different fields of internal medicine management of nonagenarian patients with a special focus on oncology and on comprehensive geriatric assessment as a base for all care decision taking.

Abstract: There are only scarce data on the management of nonagenarians with breast cancer, and more particularly on the place of radiation therapy (RT). We report a retrospective study on patients aged 90 years old or older, with breast cancer, receiving RT. Records from RT departments from five institutions were reviewed to identify patients 90 years old of age and older undergoing RT over past decade for breast cancer. Tumors' characteristics were examined, as well treatment specificities and treatment intent. 44 patients receiving RT courses were identified, mean age 92 years. Treatment was given with curative and palliative intent in 72.7% and 27.3% respectively. Factors associated with a curative treatment were performance status (PS), place of life, previous surgery, and tumor stage. Median total prescribed dose was 40 Gy (23–66). Hypo fractionation was used in 77%. Most toxicities were mild to moderate. RT could not be completed in 1 patient (2.3%). No long-term toxicity was reported. Among 31 patients analyzable for effectiveness, 24 patients (77.4%) had their diseased controlled until last follow-up, including 17 patients (54.8%) experiencing complete response. At last follow-up, 4 patients (12.9%) were deceased, cancer being cause of death for two of them. The study shows that breast/chest RT is feasible in nonagenarians. Although the definitive benefit of RT could not be addressed here, hypofractionated therapy allowed a good local control with acceptable side effects. [Copyright &y& Elsevier]

Background and Purpose: We performed a cost-effectiveness analysis (CEA) comparing an adaptive radiotherapy (ART) strategy, based on weekly replanning, aiming to correct the parotid gland overdose during treatment and expecting therefore to decrease xerostomia, when compared to a standard IMRT., Materials and Methods: We conducted the ARTIX trial, a randomized, parallel-group, multicentric study comparing a systematic weekly replanning ART to a standard IMRT. The primary endpoint was the frequency of xerostomia at 12 months, measured by stimulating salivary flow with paraffin. The CEA was designed alongside the ARTIX trial which was linked to the French national health data system (SNDS). For each patient, healthcare consumptions and costs were provided by the SNDS. The reference case analysis was based on the primary endpoint of the trial. Sensitivity and scenario analyses were performed., Results: Of the 129 patients randomly assigned between 2013 and 2018, only 2 records were not linked to the SNDS, which provides a linkage proportion of 98.4%. All of the other 127 records were linked with good to very good robustness. On the intent-to-treat population at 12 months, mean total costs per patient were €41,564 (SD 23,624) and €33,063 (SD 16,886) for ART and standard IMRT arms, respectively (p = 0.033). Incremental cost effectiveness ratio (ICER) was €162,444 per xerostomia avoided. At 24 months, ICER was €194,521 per xerostomia avoided. For both progression-free and overall survival, ART was dominated by standard IMRT., Conclusion: The ART strategy was deemed to be not cost-effective compared with standard IMRT for patients with locally advanced oropharyngeal cancer., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

Background: Glioblastoma (GBM) systematically recurs after a standard 60 Gy radio-chemotherapy regimen. Since magnetic resonance spectroscopic imaging (MRSI) has been shown to predict the site of relapse, we analyzed the effect of MRSI-guided dose escalation on overall survival (OS) of patients with newly diagnosed GBM., Methods: In this multicentric prospective phase III trial, patients who had undergone biopsy or surgery for a GBM were randomly assigned to a standard dose (SD) of 60 Gy or a high dose (HD) of 60 Gy with an additional simultaneous integrated boost totaling 72 Gy to MRSI metabolic abnormalities, the tumor bed and residual contrast enhancements. Temozolomide was administered concomitantly and maintained for 6 months thereafter., Results: One hundred and eighty patients were included in the study between March 2011 and March 2018. After a median follow-up of 43.9 months (95% CI [42.5; 45.5]), median OS was 22.6 months (95% CI [18.9; 25.4]) versus 22.2 months (95% CI [18.3; 27.8]) for HD, and median progression-free survival was 8.6 (95% CI [6.8; 10.8]) versus 7.8 months (95% CI [6.3; 8.6]), in SD versus HD, respectively. No increase in toxicity rate was observed in the study arm. The pseudoprogression rate was similar across the SD (14.4%) and HD (16.7%) groups. For O(6)-methylguanine-DNA methyltransferase (MGMT) methylated patients, the median OS was 38 months (95% CI [23.2; NR]) for HD patients versus 28.5 months (95% CI [21.1; 35.7]) for SD patients., Conclusion: The additional MRSI-guided irradiation dose totaling 72 Gy was well tolerated but did not improve OS in newly diagnosed GBM., Trial Registration: NCT01507506; registration date: December 20, 2011. https://clinicaltrials.gov/ct2/show/NCT01507506?cond=NCT01507506&rank=1., (© The Author(s) 2023.

Background: There are only scarce data on the management of nonagenarians with lung cancer, and more particularly on the place of radiation therapy. The aim of the present study was to retrospectively evaluate the efficacy and tolerance of radiotherapy (RT) in nonagenarians with thoracic cancer., Patients and Methods: Records from RT departments from four institutions were reviewed to identify patients 90 years old of age and older undergoing RT over the past decade for thoracic cancer and more particularly lung cancer. Tumors' characteristics as well as treatment specificities and its intent were examined., Results: Thirteen patients receiving RT courses were identified, mean age 91.9 years. Treatment was given with curative and palliative intent in 15.4% and 84.6%, respectively. The median total prescribed dose was 30 Gy (4-70). The median number of fractions was equal to 10 (1-35). The median dose received for each fraction was 3 Gy (1.7-7). RT could not be completed in 2 patients (15.4%). At last follow-up, 11 patients (76.9%) were deceased, cancer being the cause of death for 90% of them. Most toxicities were grade 1 or 2. Two patients (15.4% of cases) have developed grade 2 toxicity during treatment. One patient (7.7% of cases) experienced an acute grade 3 toxicity., Conclusion: The study shows that RT for thoracic cancer is feasible in nonagenarians. Although the definitive benefit of RT could not be addressed here, hypofractionated therapy allowed a certain measure of control with acceptable side effects., Competing Interests: None

Background: Despite radiotherapy (RT) technical improvements, high salivary dysfunction rates are still reported in patients with head and neck squamous cell carcinoma (HNSCC). The purpose of the present study was to report salivary glands dosimetry with volumetric-modulated arc therapy (VMAT) and intensity-modulated RT (IMRT)., Methods: Dosimetry of consecutive patients receiving IMRT or VMAT for proven HNSCC between 2007 and 2013 were retrospectively reviewed., Results: Data of 609 patients were studied. Mean dose, mean maximum dose, and mean percentage of salivary gland volume receiving at least 26 Gy (V26) of the contralateral parotid were 24.50 Gy (range, 0-70.4 Gy), 39.08 Gy (range, 0.38-76.45 Gy), and 40.92% (range, 0% to 100%), respectively. Mean and maximum dose on contralateral submandibular gland were 48.18 Gy (range, 0.19-70.73 Gy), and 61.25 Gy (range, 0-75.8 Gy), respectively., Conclusion: Target volume coverage still has to be prioritized over organs at risk (OAR) sparing with new RT techniques. Submandibular glands are not sufficiently taken into account in guidelines. © 2016 Wiley Periodicals, Inc. Head Neck 38: 1028-1034, 2016., (© 2016 Wiley Periodicals, Inc.)

Introduction: For patients with cervical cancer, intensity-modulated radiation therapy (IMRT) improves target coverage and allows dose escalation while reducing the radiation dose to organs at risk (OARs). In this study, we compared dosimetric parameters among 3-dimensional conformal radiotherapy (3D-CRT), "step-and-shoot" IMRT, and volumetric intensity-modulated arc radiotherapy (VMAT) in a series of patients with cervical cancer receiving definitive radiotherapy. Computed tomography (CT) scans of 10 patients with histologically proven cervical cancer treated with definitive radiation therapy (RT) from December 2008 to March 2010 at our department were selected for this study. The gross tumor volume (GTV) and clinical target volume (CTV) were delineated following the guidelines of the Gyn IMRT consortium that included cervix, uterus, parametrial tissues, and the pelvic nodes including presacral. The median age was 57 years (range: 30 to 85 years). All 10 patients had squamous cell carcinoma with Federation of Gynecology and Obstetrics (FIGO) stage IB-IIIB. All patients were treated by VMAT. OAR doses were significantly reduced for plans with intensity-modulated technique compared with 3D-CRT except for the dose to the vagina. Between the 2 intensity-modulated techniques, significant difference was observed for the mean dose to the small intestine, to the benefit of VMAT (p < 0.001). There was no improvement in terms of OARs sparing for VMAT although there was a tendency for a slightly decreased average dose to the rectum: - 0.65Gy but not significant (p = 0.07). The intensity modulation techniques have many advantages in terms of quality indexes, and particularly OAR sparing, compared with 3D-CRT. Following the ongoing technologic developments in modern radiotherapy, it is essential to evaluate the intensity-modulated techniques on prospective studies of a larger scale., (Copyright © 2016 American Association of Medical Dosimetrists.

Background: There are only scarce data on the management of patients aged 90years or older with cancer, and more particularly on the place of radiation therapy (RT). We report the first large study on patients (pts) aged 90years or older receiving RT., Methods and Materials: Records from RT departments from five institutions were reviewed to identify pts 90years of age and older who underwent RT for various malignant tumours treated between 2003 and 2012. Tumours' characteristics were examined, as well as treatment specificities and treatment intent., Results: 308 pts receiving 318 RT courses were identified, mean age was 93.2years (standard deviation 2.8). Treatment was given with curative and palliative intent in 44% and 56%, respectively. Factors associated with a curative treatment were performance status (PS), place of life, previous surgery and tumour stage. Median total prescribed dose was 36Gy (4-76Gy). Hypofractionation and split course were used in 88% and 7.3%, respectively. Most toxicities were mild to moderate. RT could not be completed in 23 pts (7.5%). No long-term toxicity was reported. Median overall survival was 22.9months (95CI: 15.5-42.7months). Cancer was the cause of death in 8.7% and 46% of pts treated with curative and palliative intent, respectively., Conclusion: This study shows that RT is feasible for patients aged 90years or more. PS, place of life and tumour stage were factors of the therapeutic decision. There is no reason to withdraw pts with good general health condition from potentially curative RT, provided that careful attention is paid to factors of toxicity and to geriatric vulnerabilities., (Copyright © 2014 Elsevier Ltd.

Objective: Report and discuss the management of the primitive vaginal cancer in elderly adults at a single institute., Patients and Methods: Data from patients more than 70 year-old treated for a primitive vaginal cancer at the Institut de Cancérologie de la Loire Lucien-Neuwirth was retrospectively collected., Results: From August 1999 to January 2009, 9/24 patients treated for a primitive vaginal cancer had more than 70 year-old. The median age was 81 years (7-94 years). Most patients had a performance status less or equal to 1 (n=6), a squamous cell carcinoma (n=7) and a FIGO stage less or equal to II (n=6). All patients were treated with 3D external beam radiation, 3 received concurrent chemotherapy, 3 had a supplementary brachytherapy, and 6 had a colpohysterectomy. Among 7 evaluable patients, there were 4 complete responses, 2 partial responses and one progression. Main acute toxicities were gastrointestinal (n=5), urinary (n=3), general (n=3) and cutaneous (n=2). Three patients experienced late toxicities. Four patients had a local recurrence after a mean delay of 10.8 months. At last news, 4 patients were still alive and 4/5 deaths were related to the cancer. All (n=3) patients who received the combination of radiotherapy - brachytherapy were alive and disease-free. Median overall survival was 18 months., Discussion and Conclusions: Primitive vaginal cancers are rare and aggressive tumours. Our results suggested the feasibility of the combination of radiotherapy and brachytherapy for elderly patients. Prospective trials remain needed to better define and validate the optimal strategy, especially in elderly adults., (Copyright © 2013 Elsevier Masson SAS. All rights reserved.)

Radiation oncologist often faced cancer pain, regardless the stage of cancer. Given the high prevalence of cancer pain, and its potential for profound adverse consequences, all patients with active malignancy should be routinely screened and treated for pain. Using a questionnaire developed by the pain center of the Institut de cancérologie de la Loire, we questioned in a routine day 154 patients receiving radiation in our department. On 154 assessed patients, 92% (n = 143) were treated with curative intent and 8% (n = 11) with analgesic intent. Sixty-seven (44%) and 14 (9%) declared to feel pain outside and during radiotherapy, respectively. Using the visual analogic scale, 39, 41 and 20% rated their pain between 1 and 3, 4 and 6 and more than 7, respectively. One third of patients suffering from pain had no analgesic treatment and 55% of patients felt inadequately relieved. Almost all (97%) of these noted an impact on their quality of life. Half of them (54%) were aware of a specific consultation for pain. A pain consultation was offered to 19% of respondents and 26% of patients were referred for a specialized consultation at the end of the investigation. Despite the existence of a pain center in the Institute, the pain seems insufficiently assessed and supported for patients receiving radiation therapy. Better communication between caregivers and better information should enable a more comprehensive assessment and specific treatment for cancer-pain related.

The purpose of this study is to measure the impact of an educational program to raise awareness of the increased spending energy in two different population of patients with breast cancer by using the questionnaire POPAQ (Population Physical Activity Questionnaire). This is a prospective study including two groups of 15 consecutive breast cancer patients (≤ 50 years Group 1 and Group 2 > 50 and < 70 years) followed in the department of radiotherapy at the Institute of Cancer of the Loire from January to July 2011. A questionnaire of physical activity assessment was used at two different times before the diagnosis/treatment of breast cancer (t0) and at 6 months (t6) to measure the impact of the awareness method. Comparison of different measures of daily energy expenditure (t0) between groups 1 and 2 was statistically significant (1,1803 and 9434 kJ/24 h, respectively, p = 0.0005). Daily energy expenditure of professional activity was statistically different between the two groups (1437 and 457 kJ/24 h, in groups 1 and 2, respectively; p = 0.003). Between t0 and t6, we observed a significant decrease in total energy consumption in group 1 (1,1803 to 1,0876 kJ/24 h) while there was no significant change between the group 2, except energy expended at rest (basal metabolism). There were differences in daily energy expenditure based on age may influence behavioral patterns deal with energy expenditure in physical activities. Tomorrow's challenges are to provide re-entrainment programs tailored to targeted populations.

The purpose of this study was to analyze and revisit toxicity related to chest chemoradiotherapy and to correlate these side effects with dosimetric parameters obtained using analytical anisotropic algorithm (AAA) in locally unresectable advanced lung cancer. We retrospectively analyzed data from 47 lung cancer patients between 2005 and 2008. All received conformal 3D radiotherapy using high-energy linear accelerator plus concomitant chemotherapy. All treatment planning data were transferred into Eclipse 8.05 (Varian Medical Systems, Palo Alto, CA) and dosimetric calculations were performed using AAA. Thirty-three patients (70.2%) developed acute pneumopathy after radiotherapy (grades 1 and 2). One patient (2.1%) presented with grade 3 pneumopathy. Thirty-one (66%) presented with grades 1-2 lung fibrosis, and 1 patient presented with grade 3 lung fibrosis. Thirty-four patients (72.3%) developed grade 1-2 acute oesophagic toxicity. Four patients (8.5%) presented with grades 3 and 4 dysphagia, necessitating prolonged parenteral nutrition. Median prescribed dose was 64 Gy (range 50-74) with conventional fractionation (2 Gy per fraction). Dose-volume constraints were respected with a median V20 of 23.5% (maximum 34%) and a median V30 of 17% (maximum 25%). The median dose delivered to healthy contralateral lung was 13.1 Gy (maximum 18.1 Gy). At univariate analysis, larger planning target volume and V20 were significantly associated with the probability of grade ≥2 radiation-induced pneumopathy (p = 0.022 and p = 0.017, respectively). No relation between oesophagic toxicity and clinical/dosimetric parameters could be established. Using AAA, the present results confirm the predictive value of the V20 for lung toxicity as already demonstrated with the conventional pencil beam convolution approach., (Copyright © 2012 American Association of Medical Dosimetrists.

Radiation therapy plays an essential role in the treatment of invasive breast cancer. However, prophylactic treatment of supra- and infraclavicular lymph nodes is not consensual, with different treatment depending on the centres and practitioners. Clinical indications for radiotherapy of the supra- and infraclavicular lymph nodes are often the subject of a consensus. Nevertheless, radiotherapy induces some toxicity. Various techniques have been developed. To date, conformal radiotherapy allows an accurate assessment of doses to target volumes and organs at risk, but at the cost of a sometime complex delineation. This article reviews the literature on radiation of supra- and infraclavicular lymph nodes, with a special focus on technical aspects in delineation and its potential toxicity., (Copyright © 2012 Société française de radiothérapie oncologique (SFRO).

Place of axillary radiotherapy in the management of patients with breast cancer remains debated. While the prognostic value of axillary lymph node extension has been largely demonstrated, the benefit of axillary treatment is more uncertain. Large clinical trials having demonstrated the benefit of adjuvant radiotherapy in advanced breast cancer comprised large nodal irradiation, including axillary area. Analyzing the true benefit of axillary radiotherapy is rendered difficult by heterogeneity of series, particularly when focusing on the extent of lymph node dissection. Although adjuvant axillary radiotherapy is usually recommended in patients with insufficient lymph node dissection or with bulky axillary involvement, the prognosis in these patients remains poor by metastatic evolution and such strategy exposes to increased toxicity and functional sequels. Further assessments should better define the optimal indications and the true benefit of axillary radiotherapy.

Purpose: To assess the benefits of magnetic resonance imaging (MRI) in the dosimetric treatment planning for prostate radiotherapy., Patients and Methods: Ten consecutive patients have been enrolled. They were treated for a low risk prostate adenocarcinoma. A rigid superimposition was performed between MRI and scan slides obtained at time of virtual simulation, then prostate volume was delineated by four to five physicians, on TDM slides and on MRI/TDM superimposition. For each treatment plan, we assessed the impact of MRI in terms of planned treatment volume (PTV) position, individual variability of prostate delineation and doses delivered to the critical organs. The prescribed dose was 74 Gy in 37 fractions to the PTV., Results: PTV delineated on TDM (V(TDM)) were 1.15 (SD 3.71) larger than volumes delineated on MRI. Prostate apex was 4.6 mm (SD 2.87) lower on TDM than on MRI. Posterior limit of the prostate was in mean 4 mm more posterior on TDM. The variability between physicians in terms of prostate delineation was lower using MRI. For apex, these variations were 6.8 mm using TDM, versus 3.3 mm using MRI. Mean rectal dose was 8 % lower with MRI, compared to delineation using TDM., Conclusion: Superimposition TDM/MRI improves accuracy, decreases delineation variability, and allows to spare anterior part of the rectum from irradiation. It remains unknown whether this strategy translates into clinical benefit., (Copyright © 2011 Elsevier Masson SAS. All rights reserved.)

Normofractionated radiotherapy is standard for adjuvant management of patients treated with breast conservative surgery for breast cancer. However, many elderly patients are not eligible to such strategy, either because of concurrent diseases, or because the tumor is inoperable. Several protocols of exclusive radiotherapy have been reported in the literature, frequently using hypofractionated radiotherapy and endocrine therapy. We report a case of a patient treated with exclusive endocrine and radiotherapy and address the state of the art on hypofractionated schemes for the management of elderly breast cancer patients. While hypofractionated radiotherapy does not compromise the oncologic or cosmetic outcome, there is no prospective data that assesses the place of radiotherapy for the exclusive treatment of elderly patients. This strategy should be further assessed in clinical randomized trial., (Copyright © 2011 Société française de radiothérapie oncologique (SFRO). Published by Elsevier SAS. All rights reserved.)

Objective: The purpose is to assess the physical activity of breast cancer patients using a questionnaire, the Population Physical Activity Questionnaire (POPAQ) and to compare the data with those from two female populations: one healthy population and one with a previous history of cardiovascular disease., Patients and Methods: This prospective study included 104 consecutive breast cancer patients who were addressed at the radiation oncology department, Institut de cancérologie de la Loire from March to July 2010. A questionnaire using factorial method was used for assessment of physical activity., Results: In the study population, the rest energetic expenditures of physical energy related to both rest activity and low intensity activity were higher than in the healthy patients (5,292±1,376 versus 5,520±1,248 kJ/24 h, P<0.05 and 2,583±681 versus 2,494±558 kJ/24 h, P<0.05, respectively). Conversely, the energetic expenditures of physical energy related to both high physical activity and intensive physical activity were lower than in the healthy population (882±441 versus 1,560±868 kJ/24 h, P<0.05 et 210±274 versus 340±621 kJ/24 h, P<0.05, respectively)., Conclusion: The POPAQ allows quantifying the daily physical activity and seems feasible in clinical routine in breast cancer patients. In our study, it was found that the physical activity of those patients was significantly different from that of a healthy population. Further investigations are necessary for better defining the true impact of such differences in terms of incidence and prognostic for mammary carcinoma.

Purpose: Temozolomide has significantly improved the outcome of patients with glioblastoma. However, the optimal duration of continuation treatment after chemoradiation remains uncertain. This retrospective analysis aims at assessing the feasibility, the tolerance, and the potential benefit of prolonging adjuvant temozolomide more than six months, which is the reference protocol., Patients and Methods: Forty-six patients were included in the analysis. Median age at diagnosis was 61 years old (range 40 to 77). Forty-five patients received a conformal external beam radiation with concurrent temozolomide-based chemotherapy. Then, 37 patients received adjuvant chemotherapy with temozolomide. The treatment was continued until progression or toxicity., Results: During the adjuvant phase, no treatment discontinuation for toxicity was necessary. Eight patients required dose adaptation because of toxicity. Thirty-two patients presented tumor progression during the adjuvant phase. Overall median survival was 12.3 months (range 11-13.2 months) and progression-free survival (PFS) was 7.6 months (range 5.6-9.6 months)., Conclusion: These results suggest feasibility of delivering temozolomide beyond the six months of the standard protocol, with mild toxicity and survival data at least comparable to those from literature. Prospective assessments are ongoing., (Copyright © 2011 Société française de radiothérapie oncologique (SFRO). Published by Elsevier SAS. All rights reserved.)

Radiation therapy has a major role in the management of infiltrative breast cancers. However, there is no consensus for the prophylactic treatment of the internal mammary chain (IMC), with strategies that show strong differences according to centers and physicians. Indications for internal mammary chain radiotherapy are debated, since this treatment significantly increases the dose delivered to the heart and leads to potential technical difficulties. Important prospective data recently suggested that internal mammary chain radiotherapy would not be necessary, even in cases of internal or central tumor locations, or in patients with positive axillary lymph nodes. Although these data warrant confirmation by two other prospective trials, there is evidence that the indications for internal mammary chain radiotherapy should be careful and that high quality techniques should be used for decreasing the dose delivered to the heart. This review of literature presents the state of art on the radiotherapy of internal mammary chain, with special focus on the indications, techniques, and potential toxicity., (Copyright © 2010 Société française de radiothérapie oncologique (SFRO).
