Abstract
Aspergillus fumigatus is the predominant fungal species causing pulmonary aspergillosis. The present-day anti-aspergillosis arsenal is limited, with a number of molecules occasioning severe side effects (amphotericin B) or provoking significant drug interactions (azole derivatives). Moreover, the recent emergence of azole-resistant A. fumigatus strains is a cause for concern. In this context, antimicrobial peptides (AMPs) are emerging as a promising therapeutic approach and alternative or complement to conventional antifungals.

A pan-genomic approach reveals novel Sulfurimonas clade in the ferruginous meromictic Lake Pavin. Mol Ecol Resour 2024; 24:e13923. [PMID: 38189173 DOI: 10.1111/1755-0998.13923] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Revised: 10/26/2023] [Accepted: 12/21/2023] [Indexed: 01/09/2024]
Abstract
The permanently anoxic waters in meromictic lakes create suitable niches for the growth of bacteria using sulphur metabolisms like sulphur oxidation. In Lake Pavin, the anoxic water mass hosts an active cryptic sulphur cycle that interacts narrowly with iron cycling, however the metabolisms of the microorganisms involved are poorly known. Here we combined metagenomics, single-cell genomics, and pan-genomics to further expand our understanding of the bacteria and the corresponding metabolisms involved in sulphur oxidation in this ferruginous sulphide- and sulphate-poor meromictic lake. We highlighted two new species within the genus Sulfurimonas that belong to a novel clade of chemotrophic sulphur oxidisers exclusive to freshwaters. We moreover conclude that this genus holds a key-role not only in limiting sulphide accumulation in the upper part of the anoxic layer but also constraining carbon, phosphate and iron cycling.

Abstract
Beyond classical palliative-intent irradiation schemes, there are increasing data suggesting a benefit for intensive locoregional treatments in metastatic gynecological cancers. Such approach aims at avoiding local symptoms related to tumor progression, but may also improve survival outcome by shrinking tumor burden to a microscopic state. This strategy is rarely considered upfront (in highly selected patients with very limited oligometastatic disease), but rather after systemic treatment. In case of tumor response (especially if complete response) of the metastatic sites, pelvic±para-aortic radiotherapy can be considered in combination with a brachytherapy boost to obtain long-term local control, in particular in cervical or vaginal cancer patients. Such approach seems particularly relevant when there is isolated persistence or progression of macroscopic disease within the pelvis. In parallel, there is also an increasing place for radiotherapy of oligo-metastatic sites. We review the literature on the place of radiotherapy in the management of cancers of the cervix and metastatic endometrial cancer.

Abstract
The incidence of primary renal cancer is increasing, particularly in elderly patients who may have comorbidities and/or a surgical contraindications. Stereotactic body radiotherapy has primarily been evaluated retrospectively to date. The most commonly used dose schedules are 40Gy in five fractions, 42Gy in three fractions, and 26Gy in one fraction. The results in terms of local control and toxicity are very encouraging. The advantages of stereotactic body radiotherapy compared to thermal ablative treatments are its non-invasive nature, absence of general anesthesia, ability to treat larger lesions, and those close to the renal hilum. Prospective evaluations are still necessary.

Abstract
Breast cancer is the first most common cancer worldwide, and radiation therapy has a major role to play in locoregional adjuvant treatment. In recent years, we have seen the emergence of adjuvant targeted systemic therapies improving the prognosis of patients at high risk of recurrence. Practices concerning combinations of targeted therapies and locoregional radiation therapy for non-metastatic breast cancers often remain heterogeneous due to the low level of evidence and lack of validated recommendations. This literature review covers immunotherapy, CDK 4/6 inhibitors, PARP inhibitors and anti-Her2 therapies. Combining these targeted systemic therapies with radiation therapy could potentiate local treatment. The optimal therapeutic sequence and fractionation for maximum synergistic effect remain to be defined. However, while efficacy may be enhanced, radiosensitization of healthy tissue may also lead to increased toxicity. It appears possible to continue immunotherapy, trastuzumab, pertuzumab, TDM-1 or lapatinib during locoregional breast and lymph node irradiation. PARP inhibitors and CDK4/6 inhibitors are still to be suspended, due to the lack of data in the adjuvant setting and their short half-life, which does not necessitate prolonged discontinuation. As with the new antibody-drug conjugates, prospective data are needed in conjunction with adjuvant radiation therapy.

Abstract
Background and purpose The relevance of metastasis-directed stereotactic body radiation therapy (SBRT) remains to be demonstrated through phase III trials. Multiple SBRT procedures have been published potentially resulting in a disparity of practices. Therefore, the french society of urological radiation oncolgists (GETUG) recognized the need for joint expert consensus guidelines for metastasis-directed SBRT in order to standardize practice in trials carried out by the group. Materials and methods After a comprehensive literature review, 97 recommendation statements were created regarding planning and delivery of spine bone (SBM) and non-spine bone metastases (NSBM) SBRT. These statements were then submitted to a national online two-round modified Delphi survey among main GETUG investigators. Consensus was achieved if a statement received ≥ 75 % agreements, a trend to consensus being defined as 65-74 % agreements. Any statement without consensus at round one was re-submitted in round two. Results Twenty-one out of 29 (72.4%) surveyed experts responded to both rounds. Seventy-five statements achieved consensus at round one leaving 22 statements needing a revote of which 16 achieved consensus and 5 a trend to consensus. The final rate of consensus was 91/97 (93.8%). Statements with no consensus concerned patient selection (3/19), dose and fractionation (1/11), prescription and dose objectives (1/9) and organs at risk delineation (1/15). The voting resulted in the writing of step-by-step consensus guidelines. Conclusion Consensus guidelines for SBM and NSBM SBRT were agreed upon using a validated modified Delphi approach. These guidelines will be used as per-protocole recommendations in ongoing and further GETUG clinical trials.

Abstract
Plasmids are widely involved in the dissemination of characteristics within bacterial communities. Their genomic content can be assessed by high-throughput sequencing of the whole plasmid fraction of an environment, the plasmidome. In this study, we analyzed the plasmidome of a biofilm formed in the effluents of the teaching hospital of Clermont-Ferrand (France). Our analysis discovered >350 new complete plasmids, with a length ranging from 1219 to 40,193 bp. Forty-two plasmid incompatibility (Inc) groups were found among all the plasmid contigs. Ten large plasmids, described here in detail, were reconstructed from plasmid contigs, seven of which carried antibiotic resistance genes. Four plasmids potentially confer resistance to numerous families of antibiotics, including carbapenems, aminoglycosides, colistin, and chloramphenicol. Most of these plasmids were affiliated to Proteobacteria, a phylum of Gram-negative bacteria. This study therefore illustrates the composition of an environmental mixed biofilm in terms of plasmids and antibiotic resistance genes.

Abstract
The aim of this review is to present the specificities of clinical research in radiation oncology. Objectives are similar to all research in oncology: to improve the efficacy and to decrease toxic effects. Phase III trials remain the main methodology to demonstrate an improvement in efficiency, but phase I-II and registers are also important tools to validate an improvement in the therapeutic index with new technologies. In this article we discuss the special features of end-points, selection of population, and design for radiation oncology clinical trials. Quality control of delivered treatments is an important component of these protocols. Financial issues are also discussed, in the particular context of France.

Abstract
Adjuvant radiotherapy is an essential component of the treatment of breast cancer. After conservative surgery for an infiltrating carcinoma, radiotherapy must be systematically performed, regardless of the characteristics of the disease, because it decreases the rate of local recurrence and by this way, specific mortality. A boost dose over the tumour bed is required if the patient is younger than 50 years-old. Partial breast irradiation could be routinely proposed as an alternative to whole breast irradiation, but only in selected and informed patients. For ductal carcinoma in situ, adjuvant radiotherapy must be also systematically performed after lumpectomy. After mastectomy, chest wall irradiation is required for pT3-T4 tumours and if there is an axillary nodal involvement, whatever the number of involved lymph nodes. After neoadjuvant chemotherapy and mastectomy, in case of pN0 disease, chest wall irradiation is recommended if there is a clinically or radiologically T3-T4 or node positive disease before chemotherapy. Axillary irradiation is recommended only if there is no axillary surgical dissection and a positive sentinel lymph node. Supra- and infraclavicular irradiation is advised in case of positive axillary nodes. Internal mammary irradiation must be discussed case by case, according to the benefit/risk ratio (cardiac toxicity). Hypofractionation regimens (42.5Gy in 16 fractions, or 41,6Gy en 13 or 40Gy en 15) are equivalent to conventional irradiation and must prescribe after tumorectomy in selected patients. Delineation of the breast, the chest wall and the nodal areas are based on clinical and radiological evaluations. 3D-conformal irradiation is the recommended technique, intensity-modulated radiotherapy must be proposed only in specific clinical situations. Respiratory gating could be useful to decrease the cardiac dose. Concomitant administration of chemotherapy in unadvised, but hormonal treatment could be start with or after radiotherapy.

Abstract
Basal cell carcinomas and cutaneous squamous cell carcinomas are among the most common cancerous tumors in the world. Their treatment is most often based on surgery. Adjuvant radiotherapy may be indicated in case of risk factors for recurrence or as an alternative to surgery if surgery is not feasible due to the patient's advanced age and/or co-morbidities or as an alternative to potentially mutilating surgery. Radiotherapy is also part of the therapeutic arsenal for rarer skin tumors such as Merkel cell carcinoma, cutaneous lymphomas, Kaposi's disease and cutaneous adnexal carcinomas.

Abstract
BACKGROUND Histoplasmosis caused by Histoplasma capsulatum var. duboisii (Hcd) is a rare, but probably underestimated, endemic infection described in intertropical Africa. Therefore, the epidemiology of the infection remains unclear, and there is no consensus on therapeutic management. METHODS Using a comprehensive search on different Internet databases, we collected case reports of Hcd infection published from 1993 to 2019. Epidemiological and clinical charts and therapeutic strategies were analyzed. RESULTS We found 94 well-documented cases of Hcd infection, and 30.1% of the patients were under 18 years old. Symptoms occurred in some patients several decades after leaving the endemic area. Cutaneous/subcutaneous lesions, bone infections, and lymphadenopathies, both isolated and combined, were the most frequent presentations. The human immunodeficiency virus (HIV) coinfection rate was at 20.8%, with fever, lymphadenopathies, and an absence of bone infection being the differentiating elements from patients living without HIV. The rate of disseminated forms (60.6% in our review) significantly increased as compared to studies published before 1993, but without correlation with HIV infection. The global mortality rate was at 23.4% by the end of follow-up. The outcome was not correlated with the antifungal drug prescribed, nor with HIV serologic status, but was correlated with the initiation of an antifungal therapy. CONCLUSIONS Hcd histoplasmosis is a severe fungal infection for which the precise mode of acquisition remains to be determined. There is a need for affordable and more specific diagnostic tools. Itraconazole and amphotericin B are the best therapeutic alternatives and should be available in all low-income countries of the endemic area.

Abstract
BACKGROUND Updating the pathogenesis of catheter-associated bacteriuria (CA-bacteriuria) in the intensive care unit (ICU) is needed to adapt prevention strategies. Our aim was to determine whether the main pathway of CA-bacteriuria in ICU patients was endoluminal or exoluminal. In a prospective study, quantitative urine cultures were sampled from catheter sampling sites, collector bags and the catheter outer surface near the meatus from days 1 to 15 after catheterization. The endoluminal pathway was CA-bacteriuria (defined as 102 CFU/mL) first in collector bags and then in catheters. The exoluminal pathway was CA-bacteriuria first in catheters, on day 1 in early cases and after day 1 in late cases. RESULTS Of 64 included patients, 20 had CA-bacteriuria. Means of catheterization days and incidence density were 6.81 days and 55.2/1000 catheter-days. Of 26 microorganisms identified, 12 (46.2%) were Gram positive cocci, 8 (30.8%) Gram negative bacilli and 6 yeasts. Three (11.5%) CA-bacteriuria were endoluminal and 23 (88.5%) exoluminal, of which 10 (38.5%) were early and 13 (50%) late. Molecular comparison confirmed culture findings. A quality audit showed good compliance with guidelines. CONCLUSION The exoluminal pathway of CA-bacteriuria in ICU patients predominated and surprisingly occurred early despite good implementation of guidelines. This finding should be considered in guidelines for prevention of CA-bacteriuria.

Patterns of practice of androgen deprivation therapy combined to radiotherapy in favorable and unfavorable intermediate risk prostate cancer. Results of The PROACT Survey from the French GETUG Radiation Oncology group. Cancer Radiother 2020; 24:892-897.

Abstract
PURPOSE The intermediate-risk (IR) prostate cancer (PCa) group is heterogeneous in terms of prognosis. For unfavorable or favorable IR PCa treated by radiotherapy, the optimal strategy remains to be defined. In routine practice, the physician's decision to propose hormonal therapy (HT) is controversial. The PROACT survey aimed to evaluate pattern and preferences of daily practice in France in this IR population. MATERIALS AND METHODS A web questionnaire was distributed to French radiotherapy members of 91 centers of the Groupe d'Etude des Tumeurs Uro-Genitales (GETUG). The questionnaire included four sections concerning: (i) the specialists who prescribe treatments and multidisciplinary decisions (MTD) validation; (ii) the definition of IR subsets of patients; (iii) radiotherapy parameters; (iv) the pattern of practice regarding cardiovascular (CV) and (iv) metabolic evaluation. A descriptive presentation of the results was used. RESULTS Among the 82 responses (90% of the centers), HT schedules and irradiation techniques were validated by specific board meetings in 54% and 45% of the centers, respectively. Three-fourths (76%) of the centers identified a subset of IR patients for a dedicated strategy. The majority of centers consider PSA>15 (77%) and/or Gleason 7 (4+3) (87%) for an unfavorable IR definition. Overall, 41% of the centers performed systematically a CV evaluation before HT prescription while 61% consider only CV history/status in defining the type of HT. LHRH agonists are more frequently prescribed in both favorable (70%) and unfavorable (98%) IR patients. Finally, weight (80%), metabolic profile (70%) and CV status (77%) of patients are considered for follow-up under HT. CONCLUSION To the best of our knowledge, this is the first survey on HT practice in IR PCa. The PROACT survey indicates that three-quarters of the respondents identify subsets of IR-patients in tailoring therapy. The CV status of the patient is considered in guiding the HT decision, its duration and type of drug.

Abstract
AIM Overtreatment is an actual problem in low risk localized prostate cancer (PC) management. Active surveillance (AS) is a solution to limit this problem, but eligibility criteria remained discussed. The aim was to assess possibilities of widening selection criteria for patient in AS, studying curative treatment free survival (CTFS) according to restricted or expanded eligibility criteria. METHODS We retrospectively studied patients beginning AS between 2008 and 2014, for Gleason 6 localized PC, PSA<15ng/ml,<cT3. The group "strict criteria" was defined:≤cT2a, PSA<10ng/ml, 2≤positive biopsies (PB+), total tumoral length≤3mm, tumoral invading≤50%, PSA density≤0,15ng/ml/cm3. MRI was performed at baseline and during follow-up. Radical treatment was proposed in case of biological, histological or clinical progression. Criteria associated with AS survival were analyzed by Cox regression. RESULTS One hundred eighty patients were included (follow-up 46 months). One hundred and eleven patients had "strict" criteria vs. 69 "expanded" criteria. Eighty-two patients (45%) were treated with median time of 18.2 months (CTFS was 71% at 2 years, 52% at 5 years.). The widening of the inclusion criteria was not associated with CTFS (65 vs 54% at 5 years, P=0.13). Factors significatively associated with discontinuation of AS were bilaterality (HR=2.12) and abnormal rectal digital examination cT2 (HR=2,07); MRI target (HR=2,48)) tended towards significance. CONCLUSION Our study concludes that curative treatment free survival is similar for patients included with expanded criteria compared with those included with strict criteria. However, high initial cancer volume) is associated with AS discontinuation. LEVEL OF EVIDENCE 3.

Mechanisms of late radio-induced lesions are the result of multiple and complex phenomena, with many entangled cellular and tissue factors. The biological continuum between acute and late radio-induced effects will be described, with firstly a break in homeostasis that leads to cellular redistributions. New insights into late toxicity will finally be addressed. Individual radiosensitivity is a primary factor for the development of late toxicity, and clinicians urgently need predictive tests to offer truly personalized radiation therapy. An update will be made on the various functional and genetic tests currently being validated. The management of radio-induced side effects remains a frequent issue for radiation oncologists, and an update will be made for certain specific clinical situations. Finally, an innovative management for patients with significant side effects after pelvic radiotherapy will be developed, involved mesenchymal stem cell transplantation, with the presentation of the "PRISME" protocol currently open to patients recruitment.

Abstract
Synchronous metastatic breast cancer accounts for 5 to 6% of all breast cancers in Western countries, which corresponds to nearly 2500 new cases per year in France. Irradiation of the primary tumour in cases of metastatic disease at diagnosis was historically reserved for palliative indications. However, progress in systemic treatments, a better understanding of the biological basis of metastatic dissemination, the genesis of the concept of oligometastatic disease and ablative treatments directed towards metastases are revolutionizing the management of patients with de novo stage IV breast cancer. Survival of these patients has improved markedly over the years, and several studies have investigated the carcinological benefit of local treatment of the breast tumour in patients with advanced diseases at diagnosis. This article provides an update on the role of irradiation of the primary tumour in breast cancer with synchronous metastases, and discusses its interest through published or ongoing trials.

Abstract
OBJECTIVE The aim of the Cancerology Committee of the French Association of urology (CCAFU) is to propose an update of the guidelines in the management of hormone-sensitive metastatic prostate cancer. METHODS A systematic review (Medline) of the literature from 2018 to 2020 was conducted by the CCAFU Findings. Several patterns can be defined at this stage depending on prognostic, metastatic volume, and whether metastases are synchronous or metachronous. Androgenic deprivation therapy (ADT) remains the mainstay of treatment at the metastatic stage. Docetaxel in combination with ADT improves overall survival in synchronous metastatic prostate cancer. In this situation, the combination of ADT with abiraterone is also a standard of care regardless of tumor volume. Recent data have led to the recommendation that ADT should be used in conjunction with a new generation hormone therapy (Apalutamide or Enzalutamide) in metastatic synchronous or metachronous patients, regardless of tumour volume. Local treatment of prostate cancer with radiotherapy improves survival in synchronous oligometastatic patients. Metastases-directed therapy is being evaluated. CONCLUSION This update of the French recommendations should help improve the management of patients with prostate cancer.

Abstract
L’étalement est un facteur important de récidive locale et indirectement d’évolution à distance, notamment, en cas de durée de traitement allongée. La pandémie actuelle a un impact sur les patients en cours de radiothérapie qui doivent interrompre leur traitement de manière parfois prolongée du fait de la nécessité de soins respiratoires induits par le COVID-19. Les modèles utilisés de compensation de la dose totale en cas d’interruption prolongée de la radiothérapie sont connus, mais il nous a semblé important de synthétiser afin que chaque oncologue radiothérapeute puisse proposer un traitement le plus optimal possible tant en termes de risque de récidive locale que de protection des tissus sains. L’objectif de ce type de recommandation est d’homogénéiser les pratiques de l’ensemble de la discipline.

Abstract
INTRODUCTION Sarcopenia evaluated from the measurement of skeletal muscle index (SMI) has been evaluated as a predictive factor of morbidity and mortality after surgery. The objective of this study was to evaluate whether it was predictive of morbidity and mortality in patients managed by cystectomy or tri-modality therapy (TMT), combining radiotherapy and chemotherapy after endoscopic resection of the tumour, for localized muscle-invasive bladder cancer. MATERIALS AND METHODS In all, 146 consecutive patients from 2 university hospital centres treated by cystectomy between January 2012 and April 2017 or TMT between October 2008 and October 2014 were included. The SMI was measured on axial computed-tomography at the level of the transverse process of L3, before treatment. Sarcopenia was assessed in two ways: either by SMI without muscle mass adjustment or according to the definition by Martin and al. based on gender and patient BMI, then called "adjusted sarcopenia". The primary endpoint was overall survival (OS) for sarcopenia. The secondary endpoints were OS, progression-free survival (PFS) and survival without re-admission (SRH) for the total population and for each treatment group. Survival analyses were performed using the Cox model. The association between sarcopenia and complications has been investigated by the Chi2 test. RESULTS The characteristics of sarcopenic (n=67) and non-sarcopenic (n=79) patients were comparable except for 2 criteria: older patients in the sarcopenic group and a higher proportion of neo-adjuvant chemotherapy in non-sarcopenic patients. Sarcopenia was not significantly associated with any type of survival. Sarcopenia was not associated with the proportion or severity of complications. CONCLUSION Unlike unadjusted SMI, sarcopenia was not associated with survival or complications. LEVEL OF EVIDENCE 3.

Abstract
Along with the surgeon, the gastroenterologist and the general practitioner, the radiation oncologist is involved in the follow-up of patients with rectal cancer treated by radiation. Post-treatment follow-up is recommended by major professional expert groups and consists of clinical examination, monitoring of carcinoembryonic antigen, colonoscopy and computed tomography of the abdomen and pelvis. Three recent large phase III randomized trials demonstrated a lack of survival benefit from intensive follow-up strategies in comparison with minimal follow-up. However, a follow-up program is not only important for the detection of an early disease relapse but it can be also used for the identification and the management of long-term toxicity and sequalae related to rectal cancer treatment.

Abstract
Fractionation was established more than fifty years ago as the best way to obtain a differential effect between tumors and normal tissues. However, new technologies allowed today to spare critical organs from the radiation fields. And so protracted courses of irradiation are no longer required. Hypofractionation have clear practical advantages over classical fractionation: it saves the patient time; it saves money for public health system; it reduces pressure on radiotherapy units. In several localization, it has proved to be as efficient as classical fractionation without increasing late effects. In prostate cancer, some radiobiological considerations argue in favor of a better efficiency, but clinical trials did not demonstrated differences in biological control. In conclusion, for all diseases where hypofractionation was demonstrated efficient, it must be fully implemented. Invoice procedures must be adapted to maintain a sufficient level of reimbursement of radiotherapy centers.

Abstract
PURPOSE The purpose of this study was to determine the efficacy of salvage cryotherapy for intra-prostatic and local extraprostatic recurrences after curative treatment of prostate adenocarcinoma. MATERIAL AND METHOD Twenty-eight men (mean age, 69±6 [SD] years; range: 51-82 years) treated with cryoablation for prostatic (N=21) or extraprostatic (N=7) recurrent prostate cancer after radiotherapy with or without associated prostatectomy were included. Technical success, complication and recurrences were reported. Biological recurrence was defined as an elevation ≥2ng/mL of prostate specific antigen (PSA) serum level after the treatment. RESULTS The mean follow-up was 18 months. Among the 21 patients with intraprostatic recurrence, 14 had successful cryotherapy with a mean decrease in serum prostate-specific antigen (PSA) levels of -5.7±2.6 (SD) ng/mL (range: -2.1 to -16.9ng/mL). Four patients (19%) had early progression and three patients (14%) had delayed biological recurrence (mean time: 15 months). Among the 7 patients with extraprostatic recurrence, 2/7 (291%) had successful cryotherapy with a decrease in PSA serum level of -2.7±1.6 (SD) ng/mL (range: -0.5--5.5ng/mL) and 4/7 (57%) had early biological recurrence after cryotherapy that required androgen deprivation therapy, whereas 1/7 (4%) was lost to follow-up. No major complications were observed for both intra- and extraprostatic recurrence. CONCLUSION Salvage cryoablation of locally recurrent prostate cancer after curative treatment is feasible and safe when the half prostate is treated. It could delay initiation of androgen deprivation therapy in these patients.

Abstract
BACKGROUND Early assessment of response to neoadjuvant chemoradiotherapy (CRT) is crucial in determining the most suitable treatment strategy in locally advanced oesophageal cancer (LAEC). AIMS We evaluated the impact of early metabolic response during CRT on overall survival (OS) and histological response. METHODS Patients with biopsy-proven oesophageal carcinoma underwent FDG PET/CT with evaluation of the standardized uptake value (SUV) before any treatment and during CRT after 20 Gy. RESULTS 116 patients (Male: 66.4%, Median age: 63; squamous cell carcinomas (SCC): 70%) met inclusion criteria. Median OS was 21.7 months. There was a significant positive correlation between interim metabolic response and OS. In multivariate analysis, only metabolic response using the 50% cut-off value remained significantly associated with OS (IC95% = 0.28-0.73; p = 0.001). In this statistical analysis, surgery (p = 0.007) and T stage (p = 0.023) were also correlated with OS. There was a significant correlation between early metabolic response and local recurrence (Chi-squared test p = 0.0001). CONCLUSIONS Early metabolic response using FDG PET/CT is associated with better OS, disease-free survival, local control and pathological response in patients treated by CRT for LAEC.

Abstract
The purpose of this study was to assess efficacy and tolerance of anti-programmed death (PD)-1 immunotherapy in combination with sequential involved-site radiotherapy in heavily pretreated refractory Hodgkin lymphoma. In this case series, we reported the outcome of four heavily pretreated patients with refractory Hodgkin lymphoma treated by anti-PD-1 immunotherapy and involved site radiation therapy. After a median follow-up of 13-month, all patients were alive with complete metabolic response. After radiotherapy, all four patients experienced lung toxicity, which was resolved after antibiotherapy with or without corticosteroid treatment. Anti-PD-1 immunotherapy followed by involved-site radiotherapy is feasible and showed very encouraging results in heavily pretreated patients.

Abstract
If the indications of sentinel lymph node biopsy and axillary lymph node dissection have been the subject of many trials, the indications of radiotherapy, in the absence of axillary lymph node dissection are a matter of debate. We reviewed the available literature on this topic and tried to draw some practical applications. In case of negative result of a sentinel lymph node biopsy, patients could be viewed as having pN0 disease and indications of adjuvant radiotherapy based on this paradigm. However, when the result of a sentinel lymph node biopsy was positive and no axillary lymph node dissection performed, indications of adjuvant radiotherapy are not so clear. For example, micrometastases could indicate a nodal irradiation as in the AMAROS trial, or not as in the IBCSG trial. Indications of postmastectomy radiotherapy are also not clearly defined in this setting. In the end, a clinical proposal was designed, emphasizing the unanswered questions.
