RESUMEN

INTRODUCTION: The COVID19 pandemic had a strong impact on the healthcare system, particularly in oncology. Brain tumor are usually revealed by acute and life threatening symptoms. We wanted to evaluate the possible consequences of the COVID19 pandemic in 2020 on the activity of neuro-oncology multidisciplinary tumor board in a Normandy region (France). METHODS: A descriptive, retrospective, multicenter study was conducted in the four referent centers (two universitary hospitals and two cancer centers). The main objective was to compare the average number of neuro-oncology patients presented per multidisciplinary tumor board per week between a pre-COVID19 reference period (period 1 from December 2018 to December 2019) and the pre-vaccination period (period 2 from December 2019 to November 2020). RESULTS: Across Normandy, 1540 cases were presented in neuro-oncology multidisciplinary tumor board in 2019 and 2020. No difference was observed between period 1 and 2: respectively 9.8 per week versus 10.7, P=0.36. The number of cases per week also did not significantly differ during the lockdown periods: 9.1/week versus 10.4 during the non-lockdown periods, P=0.26. The only difference observed was a higher proportion of tumor resection during the lockdown periods: 81.4% (n=79/174) versus 64.5% (n=408/1366), P=0.001. CONCLUSION: The pre-vaccination era of the COVID19 pandemic did not impact the activity of neuro-oncology multidisciplinary tumor board in the Normandy region. The possible consequences in terms of public health (excess mortality) due to this tumor location should now be investigated.

RESUMEN

BACKGROUND: Molecular factors influence relapse patterns in glioblastoma. The hotspot mutation located at position 289 of the extracellular domain of the epidermal growth factor receptor (EGFRA289mut) is associated with a more infiltrative phenotype. The primary objective of this study was to explore the impact of the EGFRA289 mutation on the pattern of relapse after chemoradiotherapy-based treatment of patients suffering from newly diagnosed glioblastoma. PATIENTS AND METHODS: An ancillary study from a prospective cohort of patients suffering from glioblastoma was conducted. All patients received radiotherapy and concomitant temozolomide. The population was divided into two groups according to EGFRA289 status (mutated versus wild-type). The primary endpoint was the overlap score (varying from 0 to 1) between the initial irradiated tumor volume (Vinit) and the relapse volume (Vr). Secondary endpoints explored the impact of EGFRA289mut on survival. RESULTS: One hundred twenty-eight patients were included and analyzed: 11% had EGFRA289mut glioblastoma (n = 14/128). EGFRA289mut glioblastomas had a relapse pattern that was more marginal than EGFRA289wt glioblastomas: a median overlap score Vinit/Vr of 0.96 was observed in the EGFRA289mut group versus 1 in the EGFRA289wt group (P = 0.05). Half of the population with EGFRA289mut tumor (n = 7/14) had a marginal relapse (i.e. overlap scoreVr/Vinit ≤ 0.95) compared to 23.7% (n = 27/114) in the EGFRA289wt group, P = 0.035. EGFRA289mut did not influence survival. CONCLUSION: We highlighted a link between the EGFRA289 mutation and the relapse pattern in glioblastoma. The independent role of EGFRA289mut and its clinical implication should now be explored in further studies.

RESUMEN

Molecular documentation at relapse of high-grade glioma is an urgent need for patient care. A prospective pilot study was conducted to assess the rate of mutation detection using targeted deep sequencing on circulating tumor DNA from cerebrospinal fluid (CSF) after chemo-radiotherapy based treatment. Fifteen patients were included: 13 patients with glioblastoma, 1 patient with gliosarcoma and 1 patient with anaplastic astrocytoma. At progression, 10/15 patients (67%) had detectable mutations in the CSF. Among them, 5/10 patients harbored at least one common mutation between initial tumor and ctDNA. CSF protein level and cfDNA concentration were higher, although not significant, in the ctDNA positive group versus ctDNA negative group (1.17g/L vs. 0.79g/L). Molecular documentation obtained from ctDNA in CSF at the time of relapse is informative in around two-thirds of the patients.

RESUMEN

The COVID-19 pandemic is changing the organization of healthcare and has a direct impact on digestive surgery. Healthcare priorities and circuits are being modified. Emergency surgery is still a priority. Functional surgery is to be deferred. Laparoscopic surgery must follow strict rules so as not to expose healthcare professionals (HCPs) to added risk. The question looms large in cancer surgery - go ahead or defer? There is probably an added risk due to the pandemic that must be balanced against the risk incurred by deferring surgery. For each type of cancer - colon, pancreas, oesogastric, hepatocellular carcinoma - morbidity and mortality rates are stated and compared with the oncological risk incurred by deferring surgery and/or the tumour doubling time. Strategies can be proposed based on this comparison. For colonic cancers T1-2, N0, it is advisable to defer surgery. For advanced colonic lesions, it seems judicious to undertake neoadjuvant chemotherapy and then wait. For rectal cancers T3-4 and /or N+, chemoradiotherapy is indicated, short radiotherapy must be discussed (followed by a waiting period) to reduce time of exposure in the hospital and to prevent infections. Most complex surgery with high morbidity and mortality - oesogastric, hepatic or pancreatic - is most often best deferred.

RESUMEN

OBJECTIVE: To evaluate the frequency of use, modalities and potential interest of locoregional irradiation (LRT) in patients with upfront metastatic head and neck squamous cell carcinoma (HNSCC). METHODS: Retrospective multicentric study. Were included all patients presenting an upfront metastatic HNSCC treated by platin-5FU- cetuximab based regimen, from 2008 to 2016. Patients with past history of cervical irradiation or HNSCC within the 5 years before metastasis diagnosis were excluded. RESULTS: 65 patients were included. 25 patients (38%) presented a response or stable disease with chemotherapy. Forty-one patients (63%) underwent a locoregional irradiation: 5 patients before chemotherapy (upfront RT), 13 patients with stable disease or response after chemotherapy (consolidation RT), and 23 patients with progressive disease. Median overall survival (OS) was 11.6 months, median progression free survival was 7.9 months. OS was significantly improved for patients who underwent LRT (median OS 16.1 vs 7.5 months, p < 0.01). Among patients who received LRT, OS trended to be better if LRT was performed as consolidation RT compared to upfront RT (median OS of 22.1 vs 15.5 months, p = 0.11). Among patients with stable disease or response after chemotherapy, there was a non-significant better OS for the 13 patients treated by LRT (median OS 22.1 vs 11.8 months, p = 0.21)). Radical dose was not associated with better locoregional control compared to palliative dose (p = 0.37). CONCLUSION: LRT is frequently performed during management of upfront metastatic HNSCC and associated with better OS. Non-progressive disease after firs-line chemotherapy seems a good way to select patients who would benefit from radical LRT.

RESUMEN

AIM OF THE STUDY: The optimal therapeutic strategy in patients with rectal cancer and synchronous unresectable metastases remains unknown. We evaluated the efficacy of FOLFIRINOX induction therapy in this setting. PATIENTS AND METHODS: Chemotherapy-naïve patients received at least 8 cycles of FOLFIRINOX. The primary end-point was the 4-month disease control (4 m DC) rate. Tumour responses were centrally reviewed and assessed by computed tomography scan for metastases (Response Evaluation Criteria in Solid Tumours criteria) and magnetic resonance imaging for rectal tumorus. With a Simon 2-stage design and a targeted (H1) 4 m DC > 75%, 65 patients were enrolled from July 2012 to February 2015: male, 78%; median age, 61 years; performance status, 0-1, 98%; liver metastases, 92%; ≥2 metastatic sites, 63%. RESULTS: Fifty-six (85%) of the 65 patients received the 8 planned FOLFIRINOX cycles. The primary objective was achieved (4 m DC rate: 94%; 95% confidence interval [CI], 86.3-97.8). Primary tumour symptoms decreased from 72% at baseline to 10% at 4 months. Response rate was 86%, and a >70% primary tumour volume decrease was seen in 63% of patients. Forty-four patients (68%) had at least one grade 3 side-effect; no toxic deaths occurred. Median follow-up was 35.0 months (95% CI, 31.3-43.7). Median progression-free survival and overall survival were 10.9 m (95% CI, 8.8-12.9) and 33.4 m (95% CI, 22.6-38.2), respectively. CONCLUSION: Upfront FOLFIRINOX is feasible and allows good local and distant control. It therefore offers the opportunity to choose the best therapeutic strategy for each patient and to personalise treatment according to the local and distant efficacy results of this induction step. TRIAL REGISTRATION: Clinicaltrials.gov, NCT01674309.

RESUMEN

OBJECTIVE: To assess the prognostic value of clinical and biological features in patients treated with second-line targeted therapies (TT) for a metastatic renal cell carcinoma (mRCC). MATERIAL AND METHODS: A retrospective study was performed including 60 patients treated with second-line TT from 2006 to 2013. Clinical and biological features were collected, including TT-induced toxicities, Heng and MSKCC prognostic scores, and renal function. Overall survival (OS) and progression-free survival (PFS) were assessed using univariate and multivariate analysis. RESULTS: The median age was 61 years [39-81]. MSKCC and Heng scores were significantly prognostic for OS and PFS (P<0.05). Hypo-albuminemia, anemia and brain metastasis were associated with poorer OS and PFS (P<0.05). Severe induced toxicities had a prognostic impact with higher OS (26 months vs 10 months, P=0.003) and PFS (5 months vs 4 months, P=0.047). Renal function impairment at the initiation of the second line was also associated with higher survival (OS=24 months vs 9 months, P=0.035 and PFS=7 months vs 4 months, P=0.043). On multivariate analysis, induced toxicity was found as an independent factor of good prognosis for OS (HR=0.36; P=0.01). CONCLUSION: Our results suggested that renal function impairment and TT-induced toxicities in the second line of treatment for mRCC have a potential prognostic interest as it had previously been reported for the first line of TT. LEVEL OF EVIDENCE: 5.

RESUMEN

PURPOSE: We aimed to compare the complication rate between port catheters (PC) and peripherally inserted central catheters (PICC) for the administration of postoperative chemotherapy for breast cancer. METHODS: All patients treated from January 2010 to August 2012 at the Centre Henri Becquerel for early breast cancer requiring postoperative chemotherapy were retrospectively screened. The primary endpoint was the occurrence of a major complication related to the central venous catheter. Major complications were defined as any grade 3 event according to CTCAE 4.0, delay in chemotherapy >7 days, change of the device, life-threatening event, event requiring a hospitalization, or a prolongation of hospitalization. RESULTS: A total of 448 patients were included; 290 had a PC and 158 a PICC. Overall, 31 major complications related to the central venous catheter were observed: 13 for patients with a PC (4.5%) and 18 for patients with a PICC (11.4%). In univariate analysis, having a PICC was the only factor significantly associated with a higher risk of major complications (HR = 2.83, p = 0.0027). We observed a trend for a higher risk of major complications for patients older than 60 years or with BMI >25 (p = 0.06). In multivariate analysis, having a PICC was the only predictive factor of major complications (HR = 2.89, p = 0.004). CONCLUSIONS: In univariate and multivariate analysis, having a PICC instead of a PC was the only predictive factor of device-related major complication. If confirmed prospectively by the NCT02095743 ongoing trial, this result might modify the management of adjuvant chemotherapy administration.

RESUMEN

OBJECTIVE: To assess the prognostic value of clinical and biological variables in the era of targeted therapies, especially induced toxicity in patients treated for metastatic renal cell carcinoma (RCC). PATIENTS AND METHODS: A retrospective single-center study was performed in patients treated in our center from 2006 to 2012. The clinical and biological variables and toxicity data were retrospectively collected. Survival rates were calculated using the Kaplan-Meier method and compared by the Log-Rank test. Multivariate analysis was also performed using the Cox model. RESULTS: One hundred and two patients were included, with a median follow-up of 20 months. The median overall survival (OS) was 21 months, and 6 months for the progression free survival (PFS). As expected, the variables included in the Mozter prognostic score had a significant impact on OS (P < 0.0001) and PFS (P < 0.0001). However, hypoalbuminemia (P < 0.0001), brain metastasis (P = 0.003) and the absence of nephrectomy (P < 0.0001) were found as poor prognosis factors for OS. In addition, severe toxicity (grade 3-4) was significantly associated with higher OS (P < 0.0001) and PFS (P = 0.0003) and appeared as an independent factor in multivariate analysis for OS (P = 0.02) and PFS (P = 0.01). CONCLUSION: Severe toxicity induced by targeted therapies was found as a prognostic factor increasing significantly the survival. Further studies are needed to assess the real value of this factor in the development of sequential therapies for the treatment of RCC.

RESUMEN

BACKGROUND: Small bowel adenocarcinoma (SBA) is a rare tumour with a poor prognosis. Molecular biology data on SBA carcinogenesis are lacking. METHODS: Expression of HER2, ß-catenin, p53 and mismatch repair (MMR) protein was assessed by immunohistochemistry. KRAS, V600E BRAF mutations and microsatellite instability were investigated. RESULTS: We obtained samples from 63 SBA patients (tumour stages: I-II: 30%; III: 35%; IV: 32%; locally advanced: 3%). HER2 overexpression (3+) was observed in 2 out of 62 patients, overexpression of p53 in 26 out of 62, abnormal expression of ß-catenin in 12 out of 61, KRAS mutation in 21 out of 49, BRAF V600E mutation in 1 out of 40 patients, MMR deficiency (dMMR) in 14 out of 61 and was consistent with Lynch syndrome in 9 out of 14 patients. All of the dMMR tumours were in the duodenum or jejunum and only one was stage IV. Median overall survival (OS) was 36.6 months (95% CI, 26.9-72.2). For all patients, in univariate analysis, stages I-II (P<0.001), WHO PS 0-1 (P=0.01) and dMMR phenotype (P=0.02) were significantly associated with longer OS. In multivariate analysis, disease stage (P=0.01) and WHO PS 0-1 (P=0.001) independently predicted longer OS. For stage IV patients, median OS was 20.5 months (95% CI: 14.6; 36.6 months). In multivariate analysis, WHO PS 0-1 (P=0.0001) and mutated KRAS status (P=0.02) independently predicted longer OS. CONCLUSION: This large study suggests that molecular alterations in SBA are closer to those in colorectal cancer (CRC) than those in gastric cancer, with low levels of HER 2 overexpression and high frequencies of KRAS mutations. The seemingly higher frequency of dMMR than in CRC may be explained by the higher frequency of Lynch syndrome in SBA patients. A dMMR phenotype was significantly associated with a non-metastatic tumour (P=0.02). A trend for a good prognosis and a duodenum or jejunum primary site was associated with dMMR.

RESUMEN

BACKGROUND AND OBJECTIVES: Definitive chemoradiotherapy (CRT) is considered curative intent treatment for locally advanced esophageal squamous cell carcinoma. Data concerning the usefulness of definitive CRT in patients with esophageal adenocarcinoma (ADC) are lacking. The aim of the study was to compare the results of definitive CRT versus surgery in patients with an ADC. METHODS: All consecutive patients with a non-metastatic ADC treated between 1994 and 2008 were retrospectively assessed. Patients were divided into two groups: surgery group (±pre-operative treatment) versus definitive CRT group. RESULTS: In surgery and definitive CRT groups, 67 and 79 patients were evaluated, respectively. A complete resection was achieved in 92.5% of patients in surgery group and a clinical complete response was observed in 49.4% of patients in definitive CRT group. Overall survival was 36.2 ± 2.0 months in surgery group versus 16.5 ± 0.8 months in definitive CRT group (P = 0.02). The predictive factors of survival were age (P < 0.01), stage (P = 0.04), WHO performance status (P < 0.01), initial weight loss (P < 0.01), and the treatment group (P < 0.01). CONCLUSIONS: The results of the study do not support definitive CRT as an alternative to surgery in esophageal ADC treatment. Definitive CRT should be reserved for patients with a major operative risk.

RESUMEN

BACKGROUND: In advanced renal cell carcinoma (RCC), sunitinib and sorafenib tyrosine kinase inhibitors (TKI) are associated with several clinical side effects, with no definitive established data concerning their clinical impact. METHODS: From June 2006 to June 2008, main clinical TKI-induced toxicities, including digestive, cardiac, dermatologic and asthenia were retrospectively collected using the NCI-CTC version 3.0 in patients treated with TKI for an RCC. RESULTS: The median overall survival was significantly improved in patients with grade 3-4 clinical toxicities (36 vs 12 months, P=0.009). In multivariate analysis, the Memorial Sloan-Kettering Cancer Center risk groups (good vs intermediate or poor) and clinical toxicities (grade 3-4 vs 1-2) were identified as independent prognostic factors of better survival (P=0.002 and P=0.02, respectively). The Charlson comorbidity index score (>7 vs <7) was identified as independent predictive factor of severe clinical TKI-induced toxicities (P=0.02). CONCLUSION: In this unselected patients of RCC, clinical TKI-related severe toxicities were more frequent in patients with comorbidities and were associated with better survival.

RESUMEN

Chemotherapy does not increase the survival time of patients treated for rectal cancer. Chemotherapy given concomitantly to radiotherapy and combined before or after radiation significantly reduces the risk of local recurrence. The sterilization of the tumour (complete pathological response) by chemotherapy is a favourable prognostic factor. New trials on optimisation of pathological complete response rates are based on using drugs effective on metastatic colorectal cancer, given prior to chemoradiotherapy and followed by a resection at least 8 weeks after the end of the radiotherapy. The level of evidence for postoperative chemotherapy is low due to lack of specific study. The indication of postoperative chemotherapy depends on the disease extent after preoperative treatment.

RESUMEN

To date, Lugol chromo-endoscopy is the reference technique to detect an esophageal neoplasia in patients with prior esophageal squamous-cell carcinoma (ESCC), but is not easy to perform without general anesthesia, which can limit its use in routine practice. The objective of this study were to compare the accuracy of white light, narrow band imaging (NBI), and Lugol to detect esophageal neoplasia in patients with a history of cured ESCC, in a prospective study. Thirty patients were prospectively included between June 2006 and June 2009. They all had a history of cured ESCC. Esophageal mucosa was examined first using white light, second NBI, and third after Lugol staining. Histology was obtained in all abnormalities detected by white light, NBI, and/or Lugol. Five neoplastic lesions in five different patients were identified at histology, four cancers, and one high-grade dysplasia. NBI and Lugol both detected all esophageal neoplastic lesions, whereas white light detected the four cancers but missed the high-grade dysplasia. In this feasibility study, NBI and Lugol both detected all identified esophageal neoplasia in very high-risk patients of ESCC. This result suggests that NBI could be used instead of Lugol to detect an esophageal neoplasia in patients with high risk of ESCC, but needs to be confirmed in a larger study.

RESUMEN

Since 2004, the clinical impact of monoclonal antibodies (mAbs) targeting the epidermal growth factor receptor (EGFR) on patients with metastatic colorectal cancer (MCRC) has been clearly established. The combination of these biological agents with conventional chemotherapy has led to a significant improvement in response rate, progression-free survival and overall survival in first-line as well as in second- or third-line treatment of MCRC. However, the high variability of response and outcome in MCRC patients treated with these anti-EGFR mAbs has highlighted the need of identifying clinical and/or molecular predictive markers to ensure appropriate use of targeted therapies. The presence of somatic KRAS mutations has been clearly identified as a predictive marker of resistance to anti-EGFR in MCRC, and the use of anti-EGFR mAbs is now restricted to patients with no detectable KRAS mutation. Several studies have indicated that amplification of EGFR, overexpression of the EGFR ligands and inactivation of the anti-oncogene TP53 are associated with sensitivity to anti-EGFR mAbs, whereas mutations of BRAF and PIK3CA and loss of PTEN expression are associated with resistance. Besides these somatic variations, germline polymorphisms such as those affecting genes involved in the EGFR pathway or within the immunoglobulin receptors may also modulate response to anti-EGFR mAbs. Until now, all these markers are not completely validated and only KRAS genotyping is mandatory in routine practice for use of the anti-EGFR mAbs in MCRC.

RESUMEN

Desmoplastic small round cell tumor (DSRCT) is a very rare but aggressive malignancy. It is usually observed in males during adolescent and early adulthood. The tumor primarily affects the intra-abdominal serosal and is characterized by distinctive histological and immunophenotypic features and by the specific reciprocal translocation EWS-WT1. Prognosis is mainly poor with a mean survival approximately of 2.5 years. However, long-term survivals have been reported using aggressive multimodal therapy based on complete surgical excision, systemic chemotherapy and radiotherapy. The addition of hyperthermic intraperitoneal chemotherapy in the multimodal approach has been reported in very few cases but no effect on survival has been clearly demonstrated. We report a case of a 51-year old adult patient presenting with a DSRCT treated with aggressive therapy based on systemic chemotherapy, complete cytoreductive surgery associated with hyperthermic intraperitoneal chemotherapy, resulting in a long term survival of 4 years.

RESUMEN

The management of patients with advanced or localized colorectal cancer (CRC) remains to date exclusively based on clinical, radiological and pathologic data. In CCR, KRAS mutations are detected in approximately 30-40% of tumours. In patients with a localized CRC, the prognostic role of KRAS mutation is not yet demonstrated with contradictory results in literature. For patients with metastatic CCR, KRAS mutations are a prognosis value for patients treated by anti-EGFR antibody. Indeed, despite the use of monoclonal antibodies against epidermal growth factor receptor (EGFR) in metastatic CRC, the detection of molecular alterations in tumours is not integrated in the routine practice for patient decision-making. In patients treated with anti-EGFR Abs for a metastatic CRC, the detection of KRAS mutations on tumour DNA is now mandatory since several recent studies have clearly demonstrated that the presence of KRAS mutations confer a resistance to these therapies. Considering the lack of sufficient data, the detection of KRAS mutations is not recommended in other clinical setting.

RESUMEN

OBJECTIVE: The optimal treatment strategy for rectal cancer (RC) with synchronous metastases remains an issue of debate. The aim of this study was to evaluate the impact of surgery and radiation on the control of pelvic symptoms in this setting. METHODS: Consecutive patients with RC and synchronous metastases were retrospectively assessed and divided into four treatment groups: surgical resection of rectal tumor (S); radiotherapy with/without chemotherapy followed by surgery (CRTS); chemoradiotherapy (CRT); and chemotherapy only (CT). Each group was evaluated in terms of duration of pelvic symptom-free periods (relative to overall survival). RESULTS: A total of 96 patients were evaluated: S: n=30; CRTS: n=21; CRT: n=27; and CT: n=18. After treatment, pelvic symptoms persisted in 14.7% patients (S=0%, CRTS=7.1%, CRT=31.8%, CT=25%; P=0.01). The relative pelvic symptom-free periods were 93.0% in the S group, 83.1% in the CRTS group, 53.0% in the CRT group and 53.2% in the CT group (P<0.01). On multivariate analysis, only surgical treatment correlated with a significant relative pelvic symptom-free period (P<0.01), with an adjusted hazards ratio of 2.80 [95% CI: 1.79-4.39]. CONCLUSION: Our results suggest that rectal resection was the most effective therapeutic procedure in selected patients with RC and synchronous metastases, offering the patients the longest pelvic symptom-free periods.
