RESUMO
Ovarian cancer is a leading cause of death from gynecological cancers worldwide. Platinum-based chemotherapy provides the cornerstone of the medical management. In first line and subsequent relapses, maintenance strategies are offered to prolong intervals between lines of chemotherapy. Current maintenance options involve bevacizumab and poly ADP-ribose polymerase inhibitors, but these lines of therapy can only be used once in the disease course. Patients in first or second platinum sensitive relapse after poly ADP-ribose polymerase inhibitors and bevacizumab represent an area of unmet medical need. This academic sponsored, international Phase II randomized trial is evaluating the combination of a therapeutic cancer vaccine (OSE2101) with anti-PD1 (pembrolizumab) as maintenance therapy, in patients with platinum-sensitive recurrence regardless of number of prior lines and no progression after platinum-based chemotherapy.Clinical Trial Registration: NCT04713514 (ClinicalTrials.gov).
Ongoing Phase II study randomizing vaccine OSE2101 +/- Pembrolizumab vs supportive care as maintenance in platinum-sensitive recurrent ovarian cancer.
RESUMO
BACKGROUND: Up to 70% of breast cancer patients report symptoms of insomnia during and after treatment. Despite the ubiquity of insomnia symptoms, they are under-screened, under-diagnosed and poorly managed in breast cancer patients. Sleep medications treat symptoms but are ineffective to cure insomnia. Other approaches such as cognitive behavioral therapy for insomnia, relaxation through yoga and mindfulness are often not available for patients and are complex to implement. An aerobic exercise program could be a promising treatment and a feasible option for insomnia management in breast cancer patients, but few studies have investigated the effects of such a program on insomnia. METHODS: This multicenter, randomized clinical trial evaluate the effectiveness of a moderate to high intensity physical activity program (45 min, 3 times per week), lasting 12 weeks, in minimizing insomnia, sleep disturbances, anxiety/depression, fatigue, and pain, and in enhancing cardiorespiratory fitness. Patients with breast cancer be recruited from six hospitals in France and randomly allocated to either the "training" or the "control" group. Baseline assessments include questionnaires [Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index questionnaire (PSQI), Hospital Anxiety Depression Scale (HADS), Epworth Sleepiness Scale (ESS)], home polysomnography (PSG), and 7-day actigraphy coupled with completion of a sleep diary. Assessments are repeated at the end of training program and at six-month follow-up. DISCUSSION: This clinical trial will provide additional evidence regarding the effectiveness of physical exercise in minimizing insomnia during and after chemotherapy. If shown to be effective, exercise intervention programs will be welcome addition to the standard program of care offered to patients with breast cancer receiving chemotherapy. TRIAL REGISTRATION: National Clinical Trials Number (NCT04867096).

BACKGROUND: PARP inhibitors (PARPi) have revolutionized the management of high-grade epithelial ovarian cancer (HGOC) treatment. However, a significant number of patients relapse or progress under PARPi, leading to the introduction of a new line of systemic therapy such as chemotherapy. In patients with a limited number of metastatic sites at progression, -referred to as an oligometastatic progression- a potential indication for local therapy followed by re-introduction or continuation of PARPi treatment rather than initiating a new line of chemotherapy could be proposed. However, the impact of such strategies on progression free survival (PFS) in these patients remains unknown. METHODS: This international multicenter retrospective study evaluated the efficacy of PARPi continuation or re-introduction in patients with HGOC after local treatment for oligometastatic progression. The main objective was to assess PFS under PARPi after local therapy (PFS post-LT). Secondary objectives included safety and overall survival (OS). RESULTS: 74 patients were identified in 20 centers between April 2020 and November 2021. 65% of patients were BRCA mutated and 92% had received ≥2 lines of prior systemic chemotherapy before the initial introduction of PARPi. Main progression sites were lymph nodes (42%), peritoneum (27%), liver (16%), other visceral (16%) and abdominal wall (4%). Local therapies included radiotherapy (45%), surgery (43%), both (7%), percutaneous thermal ablation (4%) or chemoembolization (1%). Median PFS post-LT was 11.5 months [95% CI 7.4; 17.2]. After a median follow up of 14.8 months, 6 patients (8.1%) discontinued PARPi due to toxicity. The 1-year overall survival rate was 90.7% [95% CI 79.1; 96.0]. CONCLUSIONS: With close to one year without progression or introduction of a new line of systemic therapy, this study reports the feasibility and potential benefit of this original strategy in patients with oligometastatic progression under PARPi.

PURPOSE: In an attempt to understand why cervical cancer (CC) survival is decreasing with diagnosis period among older women in France, this study aimed to estimate the effects of main prognostic factors on net survival in CC according to age. METHODS: French cancer registries databases were used to retrospectively analyze women diagnosed with CC in 2011-2012. Net survival was estimated with the Pohar-Perme method and prognostic factors (socio-demographic, clinical variables, stage at diagnosis, therapeutic management) were analyzed with Lambert and Royston's flexible parametric model. RESULTS: One thousand one hundred fifty three women with CC were identified. 30.4% were < 45, 41.4% 45-64, and 28.3% ≥ 65 years. Older women were diagnosed at a more advanced stage than younger women: 54.8% regional (FIGO IB2-IVA), 33.0% distant (IVB) in women ≥ 65 years vs 33.7% and 8.0%, respectively in women < 45 years. Half of women with regional stage of CC received recommended treatment; this rate decreased with increasing age (< 45: 66.1%, 45-64: 62.7%, ≥ 65: 29.2%). Older age was significantly associated with increased risk of death: hazard ratio 1.89 for age ≥ 65, as were regional stage (2.81), distant stage (15.99), and not receiving recommended treatment (2.26). CONCLUSION: Older women with CC diagnosed at advanced stage who do not receive standard of care are at markedly increased risk of death. Special attention to the management of older women is warranted in France, not only to diagnose cancer at an earlier stage (via gynecological follow-up in these menopaused women who remain at risk of CC), but also to ensure they receive standard of care, taking into account their overall state of health.

INTRODUCTION: Ovarian cancer (OC) is the most lethal gynecological cancer. Cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy appears to increase survival, and normothermic intraperitoneal chemotherapy (IPC) could improve overall survival (OS). Furthermore, intraperitoneal epinephrine could decrease the toxicity of chemotherapy by decreasing the systemic absorption of chemotherapy. The goal of this study was to assess the effects of CRS and IPC with intraperitoneal epinephrine, as first-line therapy, on the survival of patients with serous epithelial OC (EOC) with peritoneal metastases. METHODS: A prospective monocentric database was retrospectively searched for all patients with advanced serous EOC treated by interval or consolidative CRS plus IPC with intraperitoneal epinephrine after neoadjuvant chemotherapy. OS and disease-free survival (DFS), postoperative complications, and prognostic factors were analyzed. RESULTS: From January 2003 to December 2017, 124 patients with serous EOC were treated with interval (n = 58) or consolidative (n = 66) complete CRS plus IPC with intraperitoneal epinephrine. The median follow-up was 77.8 months, the median OS was 60.8 months, and the median DFS was 21.2 months. In our multivariate analysis, a higher Peritoneal Cancer Index (PCI) and positive lymph node status resulted in worse OS, while higher World Health Organization score, higher PCI score, and positive lymph node status were risk factors for worse DFS. Grade 3 or higher surgical morbidity occurred in 27.42% of cases; only 3.2% had grade 3 renal toxicity and mortality was 0.8%. CONCLUSION: CRS and IPC with intraperitoneal epinephrine in stage III EOC offer good OS and DFS with acceptable morbidity and mortality rates.

INTRODUCTION: Routine Electronic Monitoring of Health-Related Quality of Life (HRQoL) (REMOQOL) in clinical care with real-time feedback to physicians could help to enhance patient-centered care. We evaluated the feasibility of REMOQOL in the French context in the QOLIBRY study. The primary objective was to assess the patients' compliance with REMOQOL. METHODS: The QOLIBRY study was a single-center, prospective study conducted in the University Hospital of Besançon (France). Eligible patients were those treated with systemic therapies for breast, lung or colorectal cancer at any stage. Patients were invited to complete the EORTC QLQ-C30 questionnaire and cancer-site-specific modules before each visit on tablets and/or computers in the hospital or at home. During the consultation, physicians had real-time access to visual summaries of HRQoL scores. Compliance was assessed as adequate if at least 66% of HRQoL assessments were completed during the 4 months of follow-up. RESULTS: Between March 2016 and October 2018, 177 patients were included in the QOLIBRY study. Median age was 64 years (IQR 54-71). The proportion of patients with an adequate compliance rate was 95.5% (n = 63) in the breast cancer cohort, 98.2% (n = 55) in the colorectal cancer cohort, and 90.9% (n = 50) in the lung cancer cohort. The physicians checked the HRQoL results in 73.1% of visits and prescribed supportive care and adapted patient management in 8.3% and 5.2% of visits, respectively. CONCLUSION & PERSPECTIVES: The results of QOLIBRY study suggest that REMOQOL is feasible in the French context. However, information about HRQoL monitoring, training of the physicians in the use of the software, and recommendations for using HRQoL results to guide care are essential and must be improved.

mTOR pathway inhibitors such as rapalogs represent a promising tool to induce functional memory CD8 T cells. In our study, we investigated the combination of temsirolimus with anticancer vaccines. Using various designs of cancer vaccines (short and long peptides or the B subunit of Shiga toxin as an antigen delivery vector) and tumor models (melanoma, lung and colon cancer), we showed that the administration of temsirolimus efficiently decreased tumor growth and enhanced tumor-specific CD8 T-cell responses induced by vaccination. Furthermore, tumor-specific CD8 T cells induced by the bi-therapy (vaccine + temsirolimus) exhibit phenotypic characteristics of central memory (CD127+ CD62L+ ) CD8 T cells compared to vaccination alone. We demonstrated that regulatory CD4 T cells (Tregs ) expansion in vivo limits the efficacy of the bi-therapy by altering the antitumor CD8 T-cell responses. Finally, the use of a small molecule CCR4 antagonist to prevent Tregs induction considerably improved the efficacy of the bi-therapy by enhancing CD8 T cells-mediated antitumor immunity. Taken together, our study highlights the potential interest of combining cancer vaccines with drugs that promote memory CD8 T cells and inhibit Tregs .

Telomerase is a prototype-shared tumor Ag and represents an attractive target for anticancer immunotherapy. We have previously described promiscuous and immunogenic HLA-DR-restricted peptides derived from human telomerase reverse transcriptase (hTERT) and referred as universal cancer peptide (UCP). In nonsmall cell lung cancer, the presence of spontaneous UCP-specific CD4 T cell responses increases the survival of chemotherapy-responding patients. However, the precise mechanisms of hTERT's uptake, processing, and presentation on MHC-II molecules to stimulate CD4 T cells are poorly understood. In this work, by using well-characterized UCP-specific CD4 T cell clones, we showed that hTERT processing and presentation on MHC-II involve both classical endolysosomal and nonclassical cytosolic pathways. Furthermore, to our knowledge, we demonstrated for the first time that hTERT's internalization by dendritic cells requires its interaction with surface heparan sulfate proteoglycans. Altogether, our findings provide a novel mechanism of tumor-specific CD4 T cell activation and will be useful for the development of novel cancer immunotherapies that harness CD4 T cells.

OBJECTIVES: The goal of this study was to determine the benefit in terms of time disease control (TDC) achieved by the succession of chemotherapy beyond the third line in patients treated for recurrent epithelial ovarian cancer. Secondary objectives were to identify patients who benefited from treatments beyond 3 lines and to estimate overall survival and disease-free progression lengths. MATERIALS AND METHODS: The cohort of 122 patients was identified from a pharmacy database of patients treated with chemotherapy between 1992 and 2010. The evaluation of benefit obtained by each line was based on TDC duration, defined as the interval between the beginning of the treatment and the date of progressive disease or death. RESULTS: Median TDC durations was 4.15 (0-54.7), 4 (0-21.7), 3.34 (0-29.6), 4.97 (0-29.2), and 3.13 months (0-15) for the fourth to eighth lines, respectively. Time to disease control was longer than 6 months in 34% to 40% of patients treated by lines 4 to 8. The most important factor influencing TDC length beyond the third line was the TDC duration observed in the 2 previous lines of therapy. Median overall survival after the third line was 15.3 months (95% confidence interval, 12-20 months). Factors associated with longer overall survival after 3 lines were performance status lower than 2 (P = 0.0058), no hepatic metastasis (P = 0.0098), no pulmonary metastasis (P = 0.0003), and platinum sensitivity (P = 0.04) CONCLUSIONS: These results may justify the administration of chemotherapy beyond the third line, in particular when the 2 previous lines are effective and resulted in disease control longer than 6 months.

BACKGROUND: The Oncotype DX recurrence score (RS) assay has been validated for prediction of 10-year risk of distant recurrence and likelihood of benefit from chemotherapy in patients with estrogen receptor (ER)-positive, HER2-negative early breast cancer. Patients with high RS tumors have substantial benefit, and patients with low RS tumors have minimal if any benefit from chemotherapy. Tumor size is used as a key parameter when selecting patients for neoadjuvant chemotherapy. The aim of this study was to assess the distribution of RS in patients selected for neoadjuvant chemotherapy primarily according to tumor size. PATIENTS AND METHODS: Patients with ER-positive and HER2-negative tumors that were node-negative or had no more than 1 positive node from three trials were included in this study. Oncotype DX was performed at Genomic Health, Inc., blinded to the clinical data. Descriptive statistics were calculated for distribution of RS for all cases. RESULTS: Of 277 patients, 96 met eligibility criteria, and 81 had sufficient material for analysis. Median tumor size was 40 mm (interquartile range [IQR], 30-50 mm). Grade I, II, and III were observed in 13, 49, and 17 cases, respectively. There was a wide distribution of RS with a median of 21.4 (IQR, 16.05-26.75). In total, 23 (28.3%) had high, 28 (34.6%) intermediate, and 30 (37%) low RS results. CONCLUSION: The RS may provide relevant information for neoadjuvant treatment decisions in select patients both in clinical practice and in studies. Inclusion of low RS disease patients in neoadjuvant trials will likely only dilute the ability to look at treatment effects.

CONTEXT AND AIMS: Eribulin is used in taxane and anthracycline refractory HER2-negative metastatic breast cancers (MBC). Patients treated in pivotal clinical trials achieved low survival rates, therefore, the identification of prognostic criteria for long progression-free survival (PFS) is still an unmet medical need. In this study, we sought to determine potential prognostic criteria for long-term eribulin response in HER2-negative MBC. METHODS: Our retrospective cohort includes female patients with HER2-negative MBC treated with eribulin in Franche-Comté, France. We defined a long-term response as at least 6 months of eribulin treatment. The primary endpoint was the analysis of criteria that differ according to the progression-free survival. Secondary outcomes concerned overall survival and response rate. RESULTS: From January 2011 to April 2020, 431 patients treated with eribulin were screened. Of them, 374 patients were included. Median PFS was 3.2 months (2.8-3.7). Eighty-eight patients (23.5%) had a long-term response to eribulin. Four discriminant criteria allowed to separate PFS in 2 arms (PFS < 3 months or > 6 months) with a 78% positive predictive value: histological grade, absence of meningeal metastasis, response to prior chemotherapy, and OMS status. We have developed a nomogram combining these 4 criteria. Median overall survival was 8.5 months (7.0-9.5). CONCLUSION: Eribulin response in MBC can be driven by clinical and biological factors. Application of our nomogram could assist in the prescription of eribulin.
RESUMO
BACKGROUND: The primary aim of this retrospective study was to investigate intraindividual correlation of estrogen receptor (ER) status, progesterone receptor (PR) status, and HER2 status between primary breast cancer and metastatic breast cancer (mBC). Secondary aims included patients' characteristics, overall survival, feasibility of histopathological evaluation in the metastatic setting, and predictive factors associated with receptors status discordance. METHODS: Patients with either biopsy of metastatic relapse or surgery of metastasis were identified. Demographics, tumor characteristics, treatment characteristics, and ER, PR, and HER2 statuses were retrospectively obtained in patients' reports. Receptors statuses were assessed by immunohistochemistry with a positivity cutoff of more than 10% for ER and PR. HER2 was considered as positive if overexpression was scored at 3+ in immunohistochemistry or if amplification ratio was >2 in fluorescent in situ hybridization. RESULTS: From a cohort of 489 patients with mBC, 269 patients had histopathological samples of metastatic relapse. Histopathological analysis of the specimen confirmed the diagnosis of mBC in 235 patients. Discordance in one or more receptors between primary breast cancer and mBC was found in 99 patients (42%). A switch in receptor status was identified for ER in 17% of tumors (p = 4 × 10(-3)), PR in 29% of cancers (p < 4 × 10(-4)), and HER2 in 4% of lesions (p = .16). Exposure to chemotherapy and to anthracycline-based chemotherapy was statistically associated with switches in ER status. Seven (2%) second malignancies and three benign diseases (1%) were diagnosed. CONCLUSIONS: This study confirms that discordance in ER and PR receptor expression between the primary breast tumor and the corresponding metastatic lesions is high, whereas HER2 status remains relatively constant. Chemotherapy, and specifically anthracycline-based chemotherapy, was associated with switch in ER status. These results were obtained in a selected population of patients; further studies are warranted to confirm these data and to determine the interest of systematic rebiopsy in the metastatic setting.

Chemo-immunotherapy is the first-line standard of care for patients with PD-L1 positive metastatic triple-negative breast cancer (mTNBC). SYNERGY (NCT03616886) is a dose-finding phase I and a randomized phase II, open-label trial evaluating if targeting the immunosuppressive adenosine pathway can enhance the antitumor activity of chemo-immunotherapy. The phase I part included 6 patients with untreated locally-advanced or mTNBC to determine the safety and recommended phase II dose of the anti-CD73 antibody oleclumab in combination with the anti-PD-L1 durvalumab and 12 cycles of weekly carboplatin and paclitaxel. In the phase II part, 127 women were randomized 1:1 to receive chemo-immunotherapy, with (arm A) or without (arm B) oleclumab. The primary endpoint was the clinical benefit rate at week 24, defined as stable disease, partial or complete response per RECIST v1.1. Secondary endpoints included objective response rate, duration of response, survival outcomes (progression-free survival and overall survival), and safety. The trial did not meet its primary endpoint, as the 24-week clinical benefit rate was not significantly improved by adding oleclumab (43% vs. 44%, p = 0.61). Exploratory median progression-free survival was 5.9 months in arm A as compared to 7.0 months in arm B (p = 0.90). The safety profile was manageable in both arms.

Background: Trastuzumab is used, alone or in conjunction with standard chemotherapy, to treat HER2-positive breast cancer (BC). Although it improves cancer outcomes, trastuzumab. can lead to cardiotoxicity. Physical exercise is a safe and effective supportive therapy in the management of side effects, but the cardioprotective effects of exercise are still unclear. Objectives: The primary aim of this study was to test whether trastuzumab-induced cardiotoxicity [left ventricular ejection fraction (LVEF) under 50%, or an absolute drop in LVEF of 10%] was reduced after a supervised exercise program of 3 months in patients with HER2-positive breast cancer. Secondary endpoints were to evaluate (i) cardiotoxicity rates using other criteria, (ii) cardiac parameters, (iii) cardiorespiratory fitness and (iv) whether a change in LVEF influences the cardiorespiratory fitness. Methods: 89 women were randomized to receive adjuvant trastuzumab in combination with a training program (training group: TG; n = 46) or trastuzumab alone (control group: CG; n = 43). The primary and secondary endpoints were evaluated at the end of the supervised exercise program of 3 months (T3). Results: After exercise program, 90.5 % of TG patients and 81.8% of CG patients did not exhibit cardiotoxicity. Furthermore, whatever the used criterion, percentage of patients without cardiotoxicity were greater in TG (97.6 and 100% respectively) than in CG (90.9 and 93.9% respectively). LVEF and GLS values remained stable in both groups without any difference between the groups. In contrast, at T3, peak VO2 (+2.6 mL.min-1.kg-1; 95%CI, 1.8 to 3.4) and maximal power (+21.3 W; 95%CI, 17.3 to 25.3) increased significantly in TG, whereas they were unchanged in CG (peak VO2: +0.2 mL.min-1.kg-1; 95%CI, -0.5 to 0.9 and maximal power: +0.7 W, 95%CI, -3.6 to 5.1) compared to values measured at T0. No correlation between LVEF changes and peak VO2 or maximal power was observed. Conclusion: A 12-week supervised exercise regimen was safe and improved the cardiopulmonary fitness in particular peak VO2, in HER2-positive BC patients treated with adjuvant trastuzumab therapy. The study is under powered to come to any conclusion regarding the effect on cardiotoxicity. Clinical trial registration: www.ClinicalTrials.gov, identifier: NCT02433067.
RESUMO
Background: There is a strong rational of using anti-programmed cell death protein-1 and its ligand (anti-PD-1/L1) antibodies in human papillomavirus (HPV)-induced cancers. However, anti-PD-1/L1 as monotherapy induces a limited number of objective responses. The development of novel combinations in order to improve the clinical efficacy of an anti-PD-1/L1 is therefore of interest. Combining anti-PD-1/L1 therapy with an antitumor vaccine seems promising in HPV-positive (+) cancers. UCPVax is a therapeutic cancer vaccine composed of two separate peptides derived from telomerase (hTERT, human telomerase reverse transcriptase). UCPVax is being evaluated in a multicenter phase I/II study in NSCLC (non-small cell lung cancer) and has demonstrated to be safe and immunogenic. The aim of the VolATIL study is to evaluate the combination of atezolizumab (an anti-PD-L1) and UCPVax vaccine in a multicenter phase II study in patients with HPV+ cancers. Methods: Patients with HPV+ cancer (anal canal, head and neck, and cervical or vulvar), at locally advanced or metastatic stage, and refractory to at least one line of systemic chemotherapy are eligible. The primary end point is the objective response rate (ORR) at 4 months. Patients will receive atezolizumab every 3 weeks at a fixed dose of 1,200 mg in combination with the UCPVax vaccine at 1 mg subcutaneously. Discussion: Anti-cancer vaccines can restore cancer-immunity via the expansion and activation of tumor-specific T cells in patients lacking pre-existing anti-tumor responses. Moreover, preclinical data showed that specific TH1 CD4 T cells sustain the quality and homing of an antigen-specific CD8+ T-cell immunity. In previous clinical studies, the induction of anti-hTERT immunity was significantly correlated to survival in patients with advanced squamous anal cell carcinoma. Thus, there is a strong rational to combine an anti-cancer hTERT vaccine and an immune checkpoint inhibitor to activate and promote antitumor T-cell immunity. This pivotal proof of concept study will evaluate the efficacy and safety of the combination of a telomerase-based TH1 inducing vaccine (UCPVax) and an anti-PD-L1 (atezolizumab) immunotherapy in HPV+ cancers, as well as confirming their synergic mechanism, and settling the basis for a new combination for future clinical trials.

RESUMO
Breast cancers expressing high levels of Ki67 are associated with poor outcomes. Oncotype DX test was designed for ER+/HER2- early-stage breast cancers to help adjuvant chemotherapy decision by providing a Recurrent Score (RS). RS measures the expression of 21 specific genes from tumor tissue, including Ki67. The primary aim of this study was to assess the agreement between Ki67RNA obtained with Oncotype DX RS and Ki67IHC. Other objectives were to analyze the association between the event free survival (EFS) and the expression level of Ki67RNA; and association between RS and Ki67RNA. Herein, we report a low agreement of 0.288 by Pearson correlation coefficient test between Ki67IHC and Ki67RNA in a cohort of 98 patients with early ER+/HER2- breast cancers. Moreover, Ki67RNAhigh tumors were significantly associated with the occurrence of events (p = 0.03). On the other hand, we did not find any association between Ki67IHC and EFS (p = 0.26). We observed a low agreement between expression level of Ki67RNA and Ki67 protein labelling by IHC. Unlike Ki67IHC and independently of the RS, Ki67RNA could have a prognostic value. It would be interesting to better assess the prognosis and predictive value of Ki67RNA measured by qRT-PCR. The Ki67RNA in medical routine could be a good support in countries where Oncotype DX is not accessible.

BACKGROUND: Cancer patients are considered highly vulnerable to the COVID-19 pandemic. However, delaying cancer-specific therapies could have a deleterious effect on survival. The potential suppressive effects of chemotherapies or cancer-related microenvironment raised the question on how cancer patients' immune system responds to SARS-CoV-2 virus. METHODS: We have started a prospective monocentric trial entitled COV-CREM (NCT04365322) in April 2020. The primary objective of the trial was to assess specific immune response's intensity and diversity to SARS-CoV-2 in infected patients. RESULTS: In this study, we showed that cancer patients (28 solid tumours, 11 haematological malignancies) exposed to SARS-CoV-2 produced a high rate of specific antibodies, as observed in patients without a cancer history (n = 29). However, our results highlight a lack in the generation of T-cell responses against CoV-N, M and S proteins from the SARS-CoV-2 virus, suggesting that cancer patients failed to mount a protective T-cell immunity. Nevertheless, SARS-CoV-2 infection did not impair established immune memory since specific responses against common viruses were not hampered in cancer patients. CONCLUSION: Given the severity and the unknown evolution of the ongoing COVID-19 pandemic, it is of fundamental importance to integrate cancer patients in vaccination programs.

Adaptive Immune responses generated by SARS-CoV-2 virus in convalescent patients according to disease severity remain poorly characterized. To this end, we designed a prospective study (NCT04365322) that included 60 COVID-19 convalescent patients (1-month post infection) in two cohorts respectively entitled mild illness and severe pneumonia. The monitoring of peripheral immune responses was performed using IFNᵧ ELISpot assay. The serology index of each patient was investigated at the same time. Patients with severe pneumonia were older and had more comorbidities than patients with mild illness. T-cell responses in term of frequency and intensity were clearly distinct between mild illness and severe pneumonia patients. Furthermore, our results demonstrated that recent history of COVID-19 did not hamper viral memory T-cell pool against common viruses (Cytomegalovirus, Epstein-Barr-virus and Flu-virus). The presence of potent adaptive immunity even in patients who underwent severe pneumonia sustain the rationale for the development of protective therapeutics against SARS-CoV-2.

The impacts of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic on cancer care are multiple, entailing a high risk of death from coronavirus disease 2019 (COVID-19) in patients with cancer treated by chemotherapy. SARS-CoV-2 vaccines represent an opportunity to decrease the rate of severe COVID-19 cases in patients with cancer and also to restore normal cancer care. Patients with cancer to be targeted for vaccination are difficult to define owing to the limited contribution of these patients in the phase III trials testing the different vaccines. It seems appropriate to vaccinate not only patients with cancer with ongoing treatment or with a treatment having been completed less than 3 years ago but also household and close contacts. High-risk patients with cancer who are candidates for priority access to vaccination are those treated by chemotherapy. The very high-priority population includes patients with curative treatment and palliative first- or second-line chemotherapy, as well as patients requiring surgery or radiotherapy involving a large volume of lung, lymph node and/or haematopoietic tissue. When possible, vaccination should be carried out before cancer treatment begins. SARS-CoV-2 vaccination can be performed during chemotherapy while avoiding periods of neutropenia and lymphopenia. For organisational reasons, vaccination should be performed in cancer care centres with messenger RNA vaccines (or non-replicating adenoviral vaccines in non-immunocompromised patients). Considering the current state of knowledge, the benefit-risk ratio strongly favours SARS-CoV-2 vaccination of all patients with cancer. To obtain more data concerning the safety and effectiveness of vaccines, it is necessary to implement cohorts of vaccinated patients with cancer.

Corticosteroids are among the most prescribed drugs in oncology. The indications range from cancer-related indications for refractory symptoms, anti-cancer effects mainly in hematology, supportive measures for cancer-specific treatments and more recently immune-related adverse events induced by modern immunotherapies. In oncological emergencies, corticosteroids are common first-line treatments because of their rapid effect and wide variety of actions. In the last 5 years, with the advance of immune checkpoint inhibitors, corticosteroids are becoming routinely used to manage immune-related adverse effects. Preclinical studies suggested that corticosteroid-induced immunosuppression might dampen the activity of immunotherapies. Prospective clinical studies show that corticosteroid use is a prognostic marker for the cancer outcome in metastatic setting but does not significantly alter the patient's response to immunotherapies per se. Here, we review the state of the art on corticosteroid use in oncology, with a focus on the drugs' potential impact on immunotherapy activity. The comprehensive pharmacological characteristics of corticosteroid drugs, clinical indications, modality of administration and associated precautions for use are discussed in this article.
