[Management of bone metastasis in non-small cell lung cancer]. / Prise en charge des métastases osseuses du cancer pulmonaire non à petites cellules.

Lung cancer is notoriously known for its predisposition to metastasize to the bones. Diagnostic tools, including positron emission tomography coupled with computed tomography, offer increased sensitivity in detecting bone infiltration. Management strategies encompass a multidisciplinary approach, including pharmacological pain management, anti-resorptive therapy, radiotherapy, interventional techniques, and surgery. This article provides an in-depth analysis of the incidence and distribution of bone metastases, skeletal-related events (SRE), diagnostic imaging techniques, and contemporary therapeutic strategies to prevent SRE. Systemic anticancer therapy and pain management, although crucial for treating BM, are not discussed in this article.

Le cancer du poumon est notoirement connu pour sa prédisposition à métastaser dans les os. Les outils diagnostiques, notamment la tomographie par émission de positrons couplée à la tomodensitométrie, offrent une sensibilité accrue pour détecter l'infiltration osseuse. Les stratégies de prise en charge englobent une approche multidisciplinaire, comprenant le traitement médicamenteux de la douleur, la thérapie antirésorptive, la radiothérapie, les techniques interventionnelles ainsi que la chirurgie. Cet article propose une analyse approfondie de l'incidence et de la distribution des métastases osseuses (MO), des événements liés au squelette (SRE), des techniques d'imagerie diagnostique et des stratégies thérapeutiques contemporaines pour prévenir les SRE. Le traitement systémique anticancéreux et la gestion de la douleur, bien que cruciaux pour traiter les MO, ne sont pas discutés dans cet article.

Testing a Model of Care for Patients on Immune Checkpoint Inhibitors Based on Electronic Patient-Reported Outcomes: Protocol for a Randomized Phase II Controlled Trial.

BACKGROUND: Management of severe symptomatic immune-related adverse events (IrAEs) related to immune checkpoint inhibitors (ICIs) can be facilitated by timely detection. As patients face a heterogeneous set of symptoms outside the clinical setting, remotely monitoring and assessing symptoms by using patient-reported outcomes (PROs) may result in shorter delays between symptom onset and clinician detection. OBJECTIVE: We assess the effect of a model of care for remote patient monitoring and symptom management based on PRO data on the time to detection of symptomatic IrAEs from symptom onset. The secondary objectives are to assess its effects on the time between symptomatic IrAE detection and intervention, IrAE grade (severity), health-related quality of life, self-efficacy, and overall survival at 6 months. METHODS: For this study, 198 patients with cancer receiving systemic treatment comprising ICIs exclusively will be recruited from 2 Swiss university hospitals. Patients are randomized (1:1) to a digital model of care (intervention) or usual care (control group). Patients are enrolled for 6 months, and they use an electronic app to complete weekly Functional Assessment of Cancer Therapy-General questionnaire and PROMIS (PROs Measurement Information System) Self-Efficacy to Manage Symptoms questionnaires. The intervention patient group completes a standard set of 37 items in a weekly PROs version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) questionnaire, and active symptoms are reassessed daily for the first 3 months by using a modified 24-hour recall period. Patients can add items from the full PRO-CTCAE item library to their questionnaire. Nurses call patients in the event of new or worsening symptoms and manage them by using a standardized triage algorithm based on the United Kingdom Oncology Nursing Society 24-hour triage tool. This algorithm provides guidance on deciding if patients should receive in-person care, if monitoring should be increased, or if self-management education should be reinforced. RESULTS: The Institut Suisse de Recherche Expérimentale sur le Cancer Foundation and Kaiku Health Ltd funded this study. Active recruitment began since November 2021 and is projected to conclude in November 2023. Trial results are expected to be published in the first quarter of 2024 and will be disseminated through publications submitted at international scientific conferences. CONCLUSIONS: This trial is among the first trials to use PRO data to directly influence routine care of patients treated with ICIs and addresses some limitations in previous studies. This trial collects a wider spectrum of self-reported symptom data daily. There are some methodological limitations brought by changes in evolving treatment standards for patients with cancer. This trial's results could entail further academic discussions on the challenges of diagnosing and managing symptoms associated with treatment remotely by providing further insights into the burden symptoms represent to patients and highlight the complexity of care procedures involved in managing symptomatic IrAEs. TRIAL REGISTRATION: ClinicalTrials.gov NCT05530187; https://www.clinicaltrials.gov/study/NCT05530187. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/48386.

Development of an eHealth-enhanced model of care for the monitoring and management of immune-related adverse events in patients treated with immune checkpoint inhibitors.

PURPOSE: The use of electronic patient-reported outcome (ePRO) data in routine care has been tied to direct patient benefits such as improved quality of care and symptom control and even overall survival. The modes of action behind such benefits are seldom described in detail. Here, we describe the development of a model of care leveraging ePRO data to monitor and manage symptoms of patients treated with immune checkpoint inhibitors. METHODS: Development was split into four stages: (1) identification of an underlying theoretical framework, (2) the selection of an ePRO measure (ePROM), (3) the adaptation of an electronic application to collect ePRO data, and (4) the description of an ePRO-oriented workflow. The model of care is currently evaluated in a bicentric longitudinal randomized controlled phase II trial, the IePRO study. RESULTS: The IePRO model of care is grounded in the eHealth Enhanced Chronic Care Model. Patients are prompted to report symptoms using an electronic mobile application. Triage nurses are alerted, review the reported symptoms, and contact patients in case of a new or worsening symptom. Nurses use the UKONS 24-hour telephone triage tool to issue patient management recommendations to the oncology team. Adapted care coordinating procedures facilitate team collaboration and provide patients with timely feedback. CONCLUSION: This report clarifies how components of care are created and modified to leverage ePRO to enhance care. The model describes a workflow that enables care teams to be proactive and provide patients with timely, multidisciplinary support to manage symptoms.

[Salivary gland cancer: new therapeutic approaches]. / Cancers des glandes salivaires : nouvelles approches thérapeutiques.

Salivary gland carcinomas are rare, characterized by a diversity of histological subtypes associated with variable clinical behavior and prognosis with usually a poor response to chemotherapy. In this context, molecular alterations have been identified and represent potential therapeutic targets: overexpression of human epidermal growth factor receptor 2 (HER2) and androgen receptors in salivary duct cancer, NOTCH mutations in adenoid cystic carcinoma, NTRK gene fusion in secretory carcinoma. Screening for these molecular alterations is mandatory in all patients with recurrent or metastatic salivary gland cancer as it may allow an individualized treatment.

Les carcinomes des glandes salivaires sont rares et se caractérisent par une grande diversité de sous-types histologiques associés à des comportements cliniques différents, à un pronostic variable et à une réponse habituellement médiocre à la chimiothérapie. Dans ce contexte, des altérations moléculaires ont été identifiées et représentent de nouvelles cibles thérapeutiques : surexpression du récepteur 2 du facteur de croissance épidermique humain (HER2) et des récepteurs aux androgènes dans le cancer des canaux salivaires, mutations activatrices de NOTCH dans le carcinome adénoïde kystique, fusion de gène NTRK dans le carcinome sécrétoire notamment. Ces altérations moléculaires doivent être recherchées chez tous les patients présentant un cancer des glandes salivaires récidivant ou métastatique et permettent d'individualiser sa prise en charge.

[Oncology: what's new in 2022]. / Oncologie : ce qui a changé en 2022.

The past year has brought several innovations in medical oncology, opening up promising new options for many solid tumors, both localized and metastatic. Immunotherapy, a real spearhead of emerging therapies in metastatic diseases, is seeing its use extend to adjuvant and neoadjuvant modalities, particularly in colon and lung cancers. 2022 also sees a great deal of focus on targeted therapies, as well as on antibody-drug conjugates, which creates new standards in both breast and lung cancers. Here we present the major advances in solid tumors.

L'année écoulée a apporté son lot d'innovations en oncologie médicale, ouvrant de nouvelles options prometteuses pour bon nombre de tumeurs solides, qu'elles soient localisées ou métastatiques. L'immunothérapie, véritable fer de lance des thérapies émergentes dans les maladies métastatiques, voit son usage s'étendre à des modalités adjuvantes et néoadjuvantes, notamment dans les cancers du côlon et du poumon. 2022 donne également la part belle aux thérapies ciblées mais aussi aux conjuguées anticorps-médicaments qui apportent de nouveaux standards tant pour les cancers du sein que du poumon. Nous vous présentons ici les avancées majeures concernant les tumeurs solides.

[Targeted therapies and non-small cell carcinomas : novelties]. / Thérapies ciblées et carcinomes non à petites cellules : nouveautés.

In recent years, new therapeutic strategies for non-small cell lung cancer (NSCLC) have been developed, stemming from a better understanding of oncogenic signaling pathways. The analysis of the alterations of genes involved in NSCLC oncogenesis is now an integral part of the diagnostic approach and opens the way to so-called "targeted" therapies. In this article, we will share the latest therapeutic advances by focusing on alterations of HER2, MET, EGFR and KRAS genes, for which new dedicated treatments have become available.

Au cours de ces dernières années, de nouvelles stratégies thérapeutiques pour le cancer du poumon non à petites cellules (CPNPC) se sont développées, découlant d'une meilleure compréhension des voies de signalisation oncogéniques. L'analyse des altérations de gènes impliqués dans le développement de ce sous-type de maladie oncologique fait désormais partie intégrante de la démarche diagnostique et ouvre la voie à des thérapies dites « ciblées ¼. Nous partagerons dans cet article les dernières avancées thérapeutiques en nous intéressant aux altérations des gènes HER2, MET, EGFR et KRAS, pour lesquelles de nouveaux traitements dédiés sont disponibles.

[Management of brain metastases in 2022]. / Prise en charge des métastases cérébrales en 2022.

Brain metastases (BM) are a common occurrence of systemic cancers. Technical improvements in neuroimaging offer additional tools for an early detection of BM, to target them precisely and differentiate these lesions from other cerebral pathologies. The therapeutic tools have also evolved from neurosurgery and whole brain therapy to include stereotactic radiosurgery, targeted and immune therapies. Given the numerous treatment options available, a multidisciplinary approach is essential to offer the patient a personalized approach to optimize the sequence and combination of treatments to offer the best outcome possible. This article aims to review key elements of diagnosis, risk stratification and modern treatment paradigms in the diagnosis and management of BM.

Les métastases cérébrales (MC) sont une manifestation fréquente des cancers systémiques. Les améliorations des techniques de radiologie offrent des options supplémentaires pour détecter de manière précoce les MC, les cibler avec précision et les différencier d'autres pathologies. Les outils thérapeutiques se sont également élargis pour inclure des techniques de radiothérapie stéréotaxiques, des thérapies ciblées et des immunothérapies. Au vu des nombreuses options de traitement pour les patients souffrant de MC, une approche multidisciplinaire doit impérativement être favorisée pour personnaliser le traitement de chaque patient et améliorer le pronostic. Cet article décrit les éléments clés du diagnostic, de la stratification du risque et les paradigmes modernes de la prise en charge et des traitements des patients avec MC.

[2021 Oncology update]. / Oncologie.

Despite COVID-19 pandemic, which is still deeply affecting world economy and global health, medical oncology specialists keep pursuing their effort for the identification of new therapeutic options to improve patients' life expectancy and quality of life. 2021 confirms the immunotherapy efficacy, alone or in combination with other modalities, across several indications.

Personalized Cytokine-Directed Therapy With Tocilizumab for Refractory Immune Checkpoint Inhibitor-Related Cholangiohepatitis.

INTRODUCTION: For patients with corticosteroid (CS)-refractory immune checkpoint inhibitor-related cholangiohepatitis (irCH), no consensus exists regarding treatment, and outcomes remain poor. We evaluated the possibility of personalized treatment according to the patient's cytokine profile and the immunohistopathologic assessment of the predominant immune infiltrate type of liver tissue. METHODS: NSCLCs with CS-refractory irCH were analyzed by immunohistochemistry of liver biopsy specimen, serum cytokine panel, and assessment of peripheral blood mononuclear cell immune cell monitoring by mass cytometry. RESULTS: A total of three consecutive patients with irCH were identified. We found a predominant T-cell infiltrate and an interferon-gamma or T helper 1 proinflammatory cytokine profile. Here, we report for the first time that a T-cell-targeted therapy with the interleukin (IL)-6 receptor-neutralizing antibody tocilizumab, which inhibits signaling downstream of interferon-gamma and several other Janus kinase-dependent cytokines, is an effective single cytokine-directed therapy for CS-refractory irCH. Three patients with severe, CS-refractory irCH who were treated with tocilizumab were found to have persistent clinical and biological remission. CONCLUSIONS: Dysregulation of the IL-6/T-cell axis may contribute to the pathogenesis of CS-refractory irCH. Our observations suggest that IL-6 blockade seems to have promise in the treatment of CS-refractory irCH. The results from our three patients need to be confirmed in a larger patient population.

Gender-specific aspects of epidemiology, molecular genetics and outcome: lung cancer.

Lung cancer remains the leading cause of cancer-related deaths worldwide in women and men. In incidence, lung cancer ranks second, surpassed by breast cancer in women and prostate cancer in men. However, the historical differences in mortality and incidence rate between both sexes have changed in the last years. In the last decades, we have also witnessed an increased number of lung cancer in female never-smokers. These disparities have grown our interest in studying the impact of the gender and sex in the presentation of lung cancer. The aetiology is yet to be fully elucidated, but the data are clear so far: there is a growing divide between lung cancer presentation in women and men that will change our management and study of lung cancer. This article aims to review the sex and gender differences in lung cancer.

[Small-cell lung cancer: management and novelties]. / Cancer du poumon à petites cellules†: prise en charge et nouveautés.

Small cell lung cancer is a recalcitrant malignancy with 5-year survival rates of less than 20%. In the majority of cases, patients have metastatic disease at diagnosis despite the new screening method by low-dose CT-scan. The high throughput sequencing has deepened our understanding of its biology. While the treatment of localized disease has changed little, the arrival of immune checkpoint inhibitors have revolutionized the management of extensive disease. At the same time, new strategies involving certain potential genetic targets are being analyzed on a large scale that could become valuable therapeutic alternatives in the future. Radiation therapy remains a very useful therapeutic modality in all stages of the disease. This article aims to review the epidemiology, molecular pathology, management and innovative therapies in small-cell lung cancer.

Le cancer pulmonaire à petites cellules (CPPC) est une tumeur récalcitrante avec une survie à 5 ans de moins de 20 %. Il est fréquemment découvert à un stade métastatique malgré le nouveau dépistage par computed tomography scan low-dose. Le séquençage à haut débit a permis d'approfondir notre compréhension de sa biologie. Bien que le traitement du CPPC localisé ait peu évolué, l'immunothérapie par inhibiteurs des points de contrôle a révolutionné la prise en charge de la maladie métastatique. Parallèlement, de nouvelles stratégies impliquant certaines cibles génétiques potentielles sont en cours d'évaluation et pourraient se révéler précieuses à l'avenir. La radiothérapie reste très utile à tous les stades de la maladie. Cet article passe en revue l'épidémiologie, la pathologie moléculaire, la prise en charge et les thérapies novatrices dans le CPPC.

[Advances in Oncology 2019]. / Oncologie.

Driven by highly specialized medicine, research and the quest for personalization of treatments, oncology witnessed substantial advances in 2019. This year numerous treatments have consolidated their importance and broadened their indications. Multiple innovative treatments, currently under study, brought hope for future advances, while biomarkers, such as PD-L1, microsatellite instability (MSI), tumor mutational burden (TMB), BRCA1/2 gene mutations, and homologous recombination deficiency (HRD) allowed better selection and customization of available treatments. This article provides an overview of this year's advances in oncology.

Sous l'égide de la médecine hautement spécialisée, de la personnalisation des traitements et secondée par une recherche énergique, l'oncologie a connu en 2019 des avancées considérables. Cette année, de nombreux traitements ont consolidé leur importance et élargi leurs indications. L'annonce d'une pléthore de traitements novateurs, en étude, est source d'espoir pour l'avenir. Des biomarqueurs simples ou composites, tels que l'expression PD-L1, l'instabilité de microsatellite (MSI), la charge mutationnelle tumorale (TMB), les mutations des gènes BRCA1/2 ou un déficit du mécanisme de la recombinaison homologue des bases (HRD) permettent une meilleure sélection et personnalisation des traitements disponibles. Le but du présent article est de rassembler les avancées oncologiques de l'année.

[The new management options for lung cancer in the immunotherapy era]. / Nouvelles options thérapeutiques du cancer pulmonaire à l'ère de l'immunothérapie.

Lung cancer is the leading cause of cancer related deaths worldwide. Since the advent of immunotherapy, survival has significantly improved. Though encouraging treatment results, initially only some patients used to benefit significantly and specifically from immunotherapy administered alone. Recently, different combinations of immunotherapy treatments with cytotoxic chemotherapy and anti-angiogenic treatments were tested in order to improve the results. Six immunotherapy treatment strategies are currently approved in Switzerland for the treatment of advanced lung cancer, either in first or later line of treatment, alone or in combination with other cytotoxic treatments. In this paper we will review the results of the latest clinical trials testing immunotherapy that led to change of the standard of care for non-small cell lung cancer, and will mention the latest perspectives of the treatment for locally advanced cancers and for small cell lung cancer.

Le carcinome pulmonaire représente la première cause de mortalité par cancer dans le monde. Ces dernières années, depuis l'avènement de l'immunothérapie, la survie a été significativement améliorée. Malgré des résultats encourageants, seule une minorité de patients bénéficiaient spécifiquement et significativement du traitement par immunothérapie administré en monothérapie. Récemment, plusieurs combinaisons entre différents traitements d'immunothérapie ou avec d'autres traitements cytotoxiques et anti-angiogéniques ont été testées en vue d'améliorer ces résultats. Six stratégies d'immunothérapie sont maintenant approuvées en Suisse pour le traitement du cancer pulmonaire avancé, en première ligne ou en ligne tardive, en monothérapie ou en association avec d'autres traitements cytotoxiques. Cet article se propose de passer en revue les résultats des dernières études cliniques qui ont changé les standards thérapeutiques, testant l'immunothérapie dans le traitement du carcinome pulmonaire non à petites cellules de stade avancé, et évoquer les perspectives pour les tumeurs précoces et le cancer à petites cellules.

[High grade serous ovarian cancer 2018 : advances and controversies]. / Le cancer séreux de haut gradede l'ovaire en 2018 : avancéeset controverses.

The primary treatment of ovarian cancer consists in a complete surgical debulking followed by adjuvant chemotherapy combining platinum with taxanes. Despite this treatment, patient survival has remained stable over the last 20 years. Recently, advances in the sequence, regimens, and route of administration of treatment have enhanced effectiveness and reduced toxicity. Targeted anti-angiogenic therapy and recently PARP inhibitors are now complementing standard treatment and have improved patient progression-free survival. The development of immunotherapy, alone or in combination, brings new perspectives for the future treatment of ovarian cancer.

Le traitement initial du cancer de l'ovaire consiste en une cytoréduction chirurgicale maximale, associée à une chimiothérapie adjuvante combinant les sels de platine aux taxanes. Malgré ce traitement, la survie sans récidive des patientes est restée stable ces 20 dernières années. Récemment, les avancées dans la séquence, les schémas et la voie d'administration des traitements ont permis d'optimiser leur efficacité et réduire leur toxicité. Les traitements ciblés anti-angiogéniques et récemment les inhibiteurs PARP (poly-ADP-ribose-polymérase) sont venus compléter les traitements standards et ont permis l'amélioration de la survie sans progression des patientes. Le développement de l'immunothérapie, seule ou en association avec d'autres traitements, ouvre des nouvelles perspectives pour le traitement du cancer de l'ovaire.

mRNA expression levels and genetic status of genes involved in the EGFR and NF-κB pathways in metastatic non-small-cell lung cancer patients.

BACKGROUND: Metastatic non-small-cell lung cancer (NSCLC) has a dismal prognosis. EGFR is overexpressed or mutated in a large proportion of cases. Downstream components of the EGFR pathway and crosstalk with the NF-κB pathway have not been examined at the clinical level. We explored the prognostic significance of the mRNA expression of nine genes in the EGFR and NF-κB pathways and of BRCA1 and RAP80 in patients in whom EGFR and K-ras gene status had previously been determined. In addition, NFKBIA and DUSP22 gene status was also determined. METHODS: mRNA expression of the eleven genes was determined by QPCR in 60 metastatic NSCLC patients and in nine lung cancer cell lines. Exon 3 of NFKBIA and exon 6 of DUSP22 were analyzed by direct sequencing. Results were correlated with outcome to platinum-based chemotherapy in patients with wild-type EGFR and to erlotinib in those with EGFR mutations. RESULTS: BRCA1 mRNA expression was correlated with EZH2, AEG-1, Musashi-2, CYLD and TRAF6 expression. In patients with low levels of both BRCA1 and AEG-1, PFS was 13.02 months, compared to 5.4 months in those with high levels of both genes and 7.7 months for those with other combinations (P=0.025). The multivariate analysis for PFS confirmed the prognostic role of high BRCA1/AEG-1 expression (HR, 3.1; P=0.01). Neither NFKBIA nor DUSP22 mutations were found in any of the tumour samples or cell lines. CONCLUSIONS: The present study provides a better understanding of the behaviour of metastatic NSCLC and identifies the combination of BRCA1 and AEG-1 expression as a potential prognostic model.

Predicting response to chemotherapy with early-stage lung cancer.

A recent meta-analysis of 11,107 patients with non-small cell lung cancer who had undergone surgical resection showed that the 5-year survival benefit of adjuvant chemotherapy was 4%, and that of adjuvant chemoradiotherapy was 5%. Two trials have shown a trend toward improved survival with adjuvant paclitaxel plus carboplatin. However, the benefit of adjuvant treatment remains suboptimal. We must distinguish between patients who will not relapse-and who can thus be spared adjuvant treatment-and those who will-for whom adjuvant treatment must be personalized. Several gene expression signatures, generally containing nonoverlapping genes, provide similar predictive information on clinical outcome, and a model combining several signatures did not perform better than did each of the signatures separately. The invasiveness gene signature, containing 186 genes, includes genes involved in the nuclear factor κB pathway, the RAS-mitogen-activated protein kinase pathway, and epigenetic control of gene expression. A 15-gene signature has identified JBR.10 patients who are more sensitive to adjuvant chemotherapy.

Soporte nutricional durante el tratamiento con radiaciones ionizantes en pacientes con tumores de cabeza y cuello en estadios avanzados / Nutritional supplement during the treatment with ionizing radiations in patients with head and neck tumors in advanced stages

La desnutrición en el paciente con cáncer avanzado favorece la inmunosupresión e implica un bajo índice de Karnofsky, pobre tolerancia y respuesta a los tratamientos oncoespecíficos, ya sea con intención curativa o paliativa, alta susceptibilidad a las infecciones y, por tanto, disminuye la calidad de vida. Los pacientes con tumores localizados en cabeza y cuello en etapas avanzadas (III-IV), constituyen uno de los grupos de alto riesgo de malnutrición por la reducción de ingresos de nutrientes, la anorexia, alteraciones del mecanismo de la deglución, obstrucción mecánica de las vías digestivas superiores, entre otras. Numerosos estudios demuestran la conveniencia del soporte nutricional en estos pacientes durante el tratamiento oncoespecífico. Se realizó un estudio prospectivo que incluyó 15 pacientes con neoplasias localizadas en cabeza y cuello en etapas avanzadas, clínicamente con signos de malnutrición, para evaluar el aporte calórico-energético adicional; a todos se les administró un soporte nutricional oral (Adn-22 %) durante el tratamiento radiante para evaluar la posibilidad de mejoría en cuanto a la tolerancia y respuesta al tratamiento. De los 15 casos estudiados, 13 presentaron complicaciones al tratamiento, pero en su mayoría de ligera intensidad, sin afectar de forma significativa el tiempo de duración y la dosis total de tratamiento, con respuesta favorable en relación con el tumor.

Malnutrition in the patient with advanced cancer favors immunosuppresion and implies a low Karnofsky index, poor tolerance and response to the oncospecific curative or palliative treatments, high susceptibility to infections and, as a result, a decline of the quality of life. Patients with head and neck tumors in advanced stages (III-IV) are one of the groups of high risk for malnutrition due to the reduction of the intake of nutrients, anorexia, alterations of the deglution mechanism, and mechanical obstruction of the upper digestive tract, among other causes.Numerous studies show the convenience of the nutritional supplement in these patients during the oncospecific treatment. A prospective study that included 15 patients with head and neck neoplasias in advanced stages, and with clinical signs of malnutrition, was conducted in order to evaluate the necessary calorie-energy supplement. All of them were administered an oral nutritional supplement (Adn-22 %) during the radiation treatment to assess the possibility of improving their tolerance and response to the treatment. Of the 15 studied cases, 13 presented complications in connection with the treatment, but most them were mild, and they did not affect in a significant way the time of duration and the total dose of treatment. There was a favorable response in relation to the tumor.
