RESUMO

Gastric cancer is the fifth most common cancer and the fourth leading cause of cancer-associated death in the world. Endoscopic resection can be the treatment in selected cases of very early gastric cancer. Surgery is recommended for tumors that do not meet the criteria for endoscopic resection or for tumors with lymph node invasion but without distant metastases. Gastrectomy should include D2 lymphadenectomy without splenectomy. Perioperative or adjuvant chemotherapy improves survival and is recommended in locally advanced gastric cancer (>T1 and/or with lymph nodes positive). In locally advanced cancer with microsatellite instability (MSI), immunotherapy should be considered. Advanced unresectable or metastatic gastric cancer has a poor prognosis. The basis of the treatment is cytotoxic chemotherapy, with platinum and fluoropyrimidine doublet in the first line. Targeted therapies can be combined with chemotherapy. Trastuzumab (anti-HER2) is recommended in the first line in HER2-positive cancer. Ramucirumab (anti-VEGFR2) is recommended in the second line, in addition to paclitaxel chemotherapy. Zolbetuximab (anti-Claudine 18.2) should also be considered in the first line in Claudine 18.2-positive cancer. Immunotherapy can also be associated with chemotherapy in the first line of PD-L1-positive cancer. In HER2-positive and PD-L1-positive cancer, adjunction of trastuzumab and immunotherapy should be considered. In advanced and metastatic cancer with microsatellite instability (MSI), immunotherapy should be the first choice depending on its availability. Important progress has been made in recent years in the treatment of gastric cancer, especially due to a better understanding of molecular characteristics and heterogeneity of this disease. New targets and therapeutic approaches are being developed, which will very likely lead to changes in the management of gastric cancer.

RESUMO

Pancreatic adenosquamous carcinoma (PASC) account for <5% of pancreatic malignancies. The efficacy of modern chemotherapy regimens in patients with advanced PASC is unknown. Patients with advanced PASC from 2008 to 2021 were consecutively included in this retrospective multicenter study. Overall survival (OS) and progression-free survival (PFS) were evaluated by Kaplan-Meier method. Ninety-four PASC from 16 French centers were included (median age, 67.3 years; males, 56.4%; metastatic disease, 85.1%). The first-line treatment was chemotherapy for 79 patients (84.0%) (37 FOLFIRINOX (FX), 7 Gemcitabine-nab paclitaxel (GN) and 35 for all other regimen) or best supportive care (BSC) alone for 15 patients (16.0%). No significant difference was observed between FX and GN in terms of PFS (P = .67) or OS (P = .5). Modern regimens pooled together (FX and GN) as compared to all others chemotherapy regimens showed an improvement of overall response rate (39.5% and 9.7%, P = .002), PFS (median, 7.8 vs 4.7 months, P = .02) and OS (median, 12.7 vs 9.2 months, P = .35). This large study evaluating first-line treatment regimens in advanced PASC suggests that modern regimens as FX or GN may be preferable to all other chemotherapy regimens. These results deserve confirmation in prospective studies.

RESUMO

INTRODUCTION: Oxaliplatin-based regimens have shown promising antitumor activity in digestive neuroendocrine tumors (NETs); however, the available data are limited. Our aim was to assess the efficacy of FOLFOX (association of 5-fluorouracil with oxaliplatin) in a large series of patients with advanced digestive NETs. METHODS: All patients with advanced digestive well-differentiated NETs treated with at least 3 cycles of FOLFOX between January 2004 and December 2018 in 12 centers from the French Group of Endocrine Tumors were included. Tumor response rate according to Response Evaluation Criteria in Solid Tumors version 1.1 criteria, progression free survival (PFS), and overall survival, as well as prognostic factors, were analyzed retrospectively. RESULTS: One hundred fifty-five patients were included. Primary tumor locations were pancreas (n = 89), small intestine (n = 40), unknown with no evidence for lung primary (n = 13), stomach (n = 7), and rectum (n = 6). Median Ki-67 was 10%, and 65% of the tumors were grade 2. The partial response rate was 30% for pancreatic NETs, 12.5% for small intestine NETs, 38.5% for unknown primary NETs, 14% for gastric NETs, and 17% for rectal NETs. Significant prognostic factors for poor PFS after FOLFOX were progressive disease at the beginning of treatment (hazard ratio [HR] = 1.83, p = 0.007), hepatic involvement superior to 50% (HR = 2.67, p = 0.0001), and rectal primary tumor location (HR = 2.6, p = 0.0036). Among pancreatic NETs, insulinomas had a better median PFS (22 months) than other pancreatic NETs (9 months, p = 0.026) and showed a high rate (8/9) of serum glucose normalization. CONCLUSIONS: FOLFOX shows a promising antitumor activity in advanced digestive NETs. Rapid symptomatic response is observed in metastatic insulinomas.

RESUMO

PURPOSE: The aim of this study was to explore the beliefs, perceptions and representations of patients in order to identify the determinants of oral anticancer drugs adherence and to take action in current practice to improve patient support in digestive oncology. METHODS: We constructed a semi-directed interview guide which aimed to explore the patient's relationship with medication, their health history, their experiences at the time of the announcement of treatment, their confidence, their fears, their motivations to adhere to their treatment and the constraints linked to their treatment. The data were analysed and discussed using a thematic approach. RESULTS: Seventeen patients agreed to participate in the study. The median age was 60 years. Ten patients had colorectal cancer, 3 patients had hepatocellular carcinoma, 3 patients had gastrointestinal stromal tumour and 1 patient had neuroendocrine pancreatic tumour. We identified five categories of factors influencing adherence: demographic and socioeconomic, disease-related, treatment-related, care system-related, and patient representation and pathways' factors. A majority of patients emphasised the importance of family support in the adherence process and the convenience of per os treatment compared to other intravenous treatments. However, several negative determinants emerged such as the toxicity of the treatment, fears of forgetting to take the medication, difficulties with the galenic formulation and negative beliefs of the family. CONCLUSION: This study demonstrates the need to address the different dimensions of the patient in order to understand his or her behaviour with regard to adherence and to identify the levers for improvement.

RESUMO

BACKGROUND & AIMS: Hepatocellular carcinoma (HCC) is a common complication of chronic liver disease with diverse underlying aetiologies. REACH/REACH-2 were global phase III studies investigating ramucirumab in advanced HCC (aHCC) following sorafenib treatment. We performed an exploratory analysis of outcomes by liver disease aetiology and baseline serum viral load. METHODS: Meta-analysis was conducted in patients with aHCC and alpha-fetoprotein (AFP) ≥400 ng/mL (N = 542) from REACH/REACH-2 trials. Individual patient-level data were pooled with results reported by aetiology subgroup (hepatitis B [HBV] or C [HCV] and Other). Pre-treatment serum HBV DNA and HCV RNA were quantified using Roche COBAS AmpliPrep/COBAS TaqMan. Overall survival (OS) and progression-free survival (PFS) were evaluated using the Kaplan-Meier method and Cox proportional hazard model (stratified by study). RESULTS: Baseline characteristics were generally balanced between arms in each subgroup (HBV: N = 225, HCV: N = 127, Other: N = 190). No significant difference in treatment effect by aetiology subgroup was detected (OS interaction P-value = .23). Median OS (ramucirumab vs placebo) in months was 7.7 versus 4.5 (HR 0.74, 95% CI 0.55-0.99) for HBV, 8.2 versus 5.5 (HR 0.82, 95% CI 0.55-1.23) for HCV and 8.5 versus 5.4 (HR 0.56, 95% CI 0.40-0.79) for Other. Ramucirumab showed similar overall safety profiles across subgroups. Worst outcomes were noted in patients with a detectable HBV load. Use of HBV antiviral therapy, irrespective of viral load, was beneficial for survival, liver function and liver-specific adverse events. CONCLUSIONS: Ramucirumab improved survival across aetiology subgroups with a tolerable safety profile, supporting its use in patients with aHCC and elevated AFP.

RESUMO

Mismatch repair-deficient (dMMR) and/or microsatellite instability-high (MSI) colorectal cancers (CRC) represent about 5% of metastatic CRC (mCRC). Prognosis and chemosensitivity of dMMR/MSI mCRC remain unclear. This multicenter study included consecutive patients with dMMR/MSI mCRC from 2007 to 2017. The primary endpoint was the progression-free survival (PFS) in a population receiving first-line chemotherapy. Associations between chemotherapy regimen and survival were evaluated using a Cox regression model and inverse of probability of treatment weighting (IPTW) methodology in order to limit potential biases. Overall, 342 patients with dMMR/MSI mCRC were included. Median PFS and overall survival (OS) on first-line chemotherapy were 6.0 and 26.3 months, respectively. For second-line chemotherapy, median PFS and OS were 4.4 and 21.6 months. Longer PFS (8.1 vs. 5.4 months, p = 0.0405) and OS (35.1 vs. 24.4 months, p = 0.0747) were observed for irinotecan-based chemotherapy compared to oxaliplatin-based chemotherapy. The association was no longer statistically significant using IPTW methodology. In multivariable analysis, anti-VEGF as compared to anti-EGFR was associated with a trend to longer OS (HR = 1.78, 95% CI 1.00-3.19, p = 0.0518), whatever the backbone chemotherapy used. Our study shows that dMMR/MSI mCRC patients experienced short PFS with first-line chemotherapy with or without targeted therapy. OS was not different according to the chemotherapy regimen used, but a trend to better OS was observed with anti-VEGF. Our study provides some historical results concerning chemotherapy in dMMR/MSI mCRC in light of the recent nonrandomized trials with immune checkpoint inhibitors.

RESUMO

INTRODUCTION: Surveillance of gastric precancerous lesions (GPL) is recommended, but the data on their clinical and endoscopic management in a "real-life" practice are limited. Our aim was to study the modalities of endoscopic management of patients with GPL in France. DESIGN: All the patients diagnosed with GPL in our center between 2000 and 2015 were grouped and analyzed according to the most severe GPL found, in the following order: atrophic gastritis only (AG), intestinal metaplasia (IM), low grade dysplasia (LGD), high grade dysplasia (HGD). RESULTS: Out of 16,764 patients having undergone upper endoscopy with gastric biopsies, 507 were identified with GPL (detection rate 3.2%). Overall, Helicobacter pylori infection was found in 41% of patients. IM was by far the most frequently found lesion (79%), followed by LGD (17%), HGD (2%), and AG only (2%). H. pylori infection rate was decreasing, while the age of the patients was increasing, together with the increasing severity of GPL (p = 0.005). Only 28% of the patients had at least one follow-up endoscopy. No correlation was found between the endoscopist's appreciation of the mucosa and histological results. CONCLUSION: In France, GPL can be expected in about 3% of patients undergoing upper endoscopy with gastric biopsies for any reason. The correlation between the endoscopic evaluation and histology is poor. Spreading of published guidelines should improve the management of patients with GPL in the future.

RESUMO

BACKGROUND: Perivascular epithelioid cell tumor, an extremely rare mesenchymal tumor, could be ubiquitous but rarely arises from pancreas. Surgery is considered the most appropriate treatment. Nevertheless, activation of mTOR pathway seems to be a common pathogenic event in PEComas paving the way to chemotherapy by mTOR inhibitor. METHOD: A 17 year-old man presented a hypervascular tumor of 55 mm, located in the head of pancreas without bile duct or pancreatic duct compression. RESULTS: Histopathology showed epithelioid cells with clear or focally granular eosinophilic cytoplasm with melanocytic (HMB-45, Melan-A) and myoid markers which confirmed diagnosis of PEComa. Given the absence of worrisome feature, we ruled out surgery and decided to initiate treatment with Sirolimus, an mTOR inhibitor. After 3.5 years, we showed a significant reduction in size of the tumor. CONCLUSION: This first case of pancreatic PEComa treated by mTOR inhibitor without surgery suggests a good efficiency of this therapy.

RESUMO

PURPOSE: In case reports or small studies, percutaneous endoscopic caecostomy (PEC) has been proposed as an alternative to the Malone intervention to perform antegrade colonic enemas. Our goal was to assess the feasibility, efficacy, and tolerance of PEC in a large group of patients with refractory colorectal functional disorders. METHODS: From September 2006 to April 2014, all patients undergoing PEC for constipation, fecal incontinence, and incontinence after rectal resection in two expert centers were studied. The PEC procedure consisted in anchoring the caecum to the abdominal wall (caecopexy) and placing a specifically designed tube in the colonic lumen to perform antegrade enemas. The quality of life (GIQLI), constipation (Kess), and incontinence (Cleveland) scores were assessed before PEC and at 3, 6, 12, and 24 months. RESULTS: A total of 69 patients were included. GIQLI scores were significantly improved in constipation group (n = 43), incontinence group (n = 19), and rectal resection group (n = 10). In the constipation group, Kess score decreased from 25.9 before PEC to 20.6 at 2 years (p = 0.01). In the incontinence and post-rectal resection groups, Cleveland scores decreased from 14.3 before PEC to 2.7 at 6 months (p = 0.01) and to 10.4 at 2 years (p = 0.04). Overall, PEC was considered successful by patients in 58%, 74%, and 90% of cases, in constipation, incontinence, and rectal resection groups, respectively. Chronic pain (52%) at the catheter site was the most frequent complication. CONCLUSIONS: Percutaneous endoscopic caecostomy for antegrade colonic enemas improves significantly the quality of life of patients with colorectal disorder refractory to medical treatment.

RESUMO

BACKGROUND: Hepatocholangiocarcinoma (cHCC-ICC) is a rare liver tumour for which no data on chemosensitivity exist. The aims of this multicentre study were to evaluate overall survival (OS), progression-free survival (PFS), and prognostic factors in cHCC-ICC treated by gemcitabine plus platinum as first-line. METHODS: Unresectable cHCC-ICC treated by gemcitabine plus platinum-based chemotherapy between 2008 and 2017 were retrospectively analysed. Diagnosis was based on histology or, in case of ICC or HCC histology, on discordant computerised tomography scan enhancement patterns associated with discordant serum tumour marker elevation suggesting the alternative tumour. OS and PFS were evaluated by Kaplan-Meier method and prognostic factors by Log-rank test and Cox model. RESULTS: Among 30 patients included, cHCC-ICC was histologically proven in 22 (73.3%). 18 (60%) received gemcitabine plus oxaliplatin (GEMOX), 9 (30%) GEMOX plus bevacizumab, and 3 (10%) gemcitabine plus cisplatin. RECIST criteria were reported in 28 patients: 8 (28.6%) showed partial response, 14 (50%) stable disease, and 6 (21.4%) tumour progression at first evaluation. Median PFS and OS were 9.0 and 16.2 months, respectively. Serum bilirubin ⩾30 µmol l-1 (P=0.001) and positive serology for HBV and/or HCV (P=0.014) were independent poor prognostic factors for OS. CONCLUSIONS: Gemcitabine plus platinum-based chemotherapy is effective as first-line for advanced cHCC-ICC.

RESUMO

Gastric cancer is the third leading cause of cancer-related death worldwide, but the mechanisms of gastric carcinogenesis are not completely understood. Recently, the role of cholinergic neuronal pathways in promoting this process has been demonstrated. Our aim was to extend these studies and to evaluate, using an in vitro model of tumorspheres, the effect of acetylcholine on human gastric cancer cells, and the role of acetylcholine receptors and of the nitric oxide pathway, in this effect. The gastric cancer cell line MKN-45 of the diffuse type of gastric cancer was cultured in the presence of acetylcholine, or different agonists or inhibitors of muscarinic and nicotinic acetylcholine receptors, or nitric oxide donor or inhibitor of the nitric oxide pathway, and the number and size of tumorspheres were assessed. The expression of cancer stem cell markers (CD44 and aldehyde dehydrogenase) was also evaluated by immunofluorescence and quantitative reverse transcription polymerase chain reaction. We showed that acetylcholine increased both the number and size of tumorspheres and that this effect was reproduced with both muscarinic and nicotinic acetylcholine receptors agonists and was inhibited by both receptor antagonists. The nitric oxide donor stimulated the tumorsphere formation, while the nitric oxide synthesis inhibitor inhibited the stimulatory effect of acetylcholine. Moreover, acetylcholine increased the expression of stem cell markers on gastric cancer cells. These results indicate that acetylcholine induces the stem cell properties of gastric cancer cells and both muscarinic and nicotinic receptors and a nitrergic pathway might be involved in this effect.

RESUMO

BACKGROUND: Obesity is associated with a risk of gastroesophageal reflux disease. The pharmacodynamic efficacy of proton pump inhibitors has not been specifically evaluated in obese subjects. The aim of this study was to compare the antisecretory response to a single oral dose of 20 mg rabeprazole, 20 mg omeprazole and placebo in obese subjects. METHODS: Gastric pH was monitored for 24 hours on three separate occasions in eighteen H. pylori-negative, asymptomatic obese subjects. Subjects were given omeprazole, rabeprazole or placebo in a randomized order and in a double-blind fashion. The main analysis criterion was 24-h percent of time post dose with intragastric pH above 3; secondary criteria were percentage of time above pH 4, median pH, [H+] concentrations and nocturnal acid breakthrough (NAB). Results were analyzed using linear mixed models and Wilks test comparing variances. RESULTS: 24-h median [IQ] percentages of time with gastric pH above 3 and 4 were higher with rabeprazole than omeprazole (46 [37-55] vs. 30 [15-55] %, 9 [5-11] % for placebo) but the differences did not reach statistical significance (p = 0.11 and 0.24, respectively). Median acid concentrations were significantly lower with rabeprazole than with omeprazole and placebo (22 [14-53] vs. 54 [19-130] and 95 [73-170] mmoles/l, p < 0.01) for all periods. The number of NAB was significantly lower with rabeprazole than with omeprazole (median 1 [1,2] vs. 2 [1-3], p = 0.04). Variances of 24-h data (pH above 3 and 4, median pH, [H+] concentrations) were significantly lower with rabeprazole than with omeprazole (p < 0.0001). CONCLUSIONS: In asymptomatic obese subjects the gastric antisecretory response to a single dose of rabeprazole and omeprazole was strong and not significantly different between drugs despite a significantly more homogeneous response with rabeprazole.

RESUMO

Hepatocellular carcinoma (HCC) is a disease with a poor prognosis, often diagnosed at an advanced stage. Therapeutic options have developed considerably in recent years, particularly with trans-arterial treatments. Systemic treatments have also evolved significantly, with the rise of immune checkpoint inhibitors (ICI) as first-line treatment for advanced HCC. The combination of loco-regional treatments and ICI is opening up new prospects and is the subject of numerous clinical trials. Recently, two global phase 3 trials investigating ICI-based adjuvant combinations have demonstrated improvements in recurrence-free survival or progression-free survival in patients treated with resection, ablation, or trans-arterial chemoembolization. However, mature data and overall survival results are still awaited but will be difficult to interpret. We are at the start of a new era of combinations of loco-regional treatments and immunotherapy. The identification of the best therapeutic strategies and predictive biomarkers is a crucial issue for future standards in clinical practice.

RESUMO

A solitary bone plasmacytoma is a rare tumor. Intrahepatic cholangiocarcinoma is the second most common primary liver cancer after hepatocellular carcinoma. We present the case of a 48-year-old female patient who consulted for recent back pain, with a final diagnosis of T10 solitary plasmacytoma and synchronous intrahepatic cholangiocarcinoma. Imaging suggested cholangiocarcinoma with bone metastasis. The patient underwent neurosurgical management with laminectomy, arthrodesis, and arthrectomy, with biopsies revealing monotypic kappa plasmacytic proliferation. Liver biopsies revealed an adenocarcinoma with expression of cytokeratin 19, cytokeratin 7, N-cadherin, and high expression of carbonic anydrase IX. The plasmacytoma was treated with external radiotherapy. The cholangiocarcinoma was treated with selective internal radiation therapy and concomitant systemic treatment with combinations of cisplatin and durvalumab, with capecitabine during radiotherapy, switched for gemcitabine after completion of irradiation. One year after initial management, imaging revealed a partial metabolic response of the intrahepatic cholangiocarcinoma, and a complete metabolic response of the plasmacytoma. This case illustrates the importance of not ignoring two primary tumors and the management of two concomitant treatments exploiting potential therapeutic synergies and limiting expected toxicities.

RESUMO

PURPOSE: Managing hepatocellular carcinoma (HCC) in patients with a transjugular intrahepatic portosystemic shunt (TIPS) is becoming increasingly common. This study aimed to evaluate the safety and efficacy of percutaneous thermal ablation for treating HCC in patients with TIPS. METHODS: This retrospective longitudinal study was conducted at Nantes University Hospital. The main inclusion criteria were patients undergoing percutaneous thermal ablation for HCC. Patients with a pre-existing TIPS were included in the 'TIPS group'. A 1:1 control group without TIPS, the 'n-TIPS group', was created for this case-control study. The primary endpoints were overall survival and progression-free survival over 12 months. Safety was assessed by comparing complications between the groups. RESULTS: Between 2008 and 2020, 371 patients underwent percutaneous thermal ablation for HCC. The 'TIPS group' included 34 patients (66 nodules), while 34 patients (84 nodules) were randomly assigned to the 'n-TIPS group.' Overall survival rates at 1 year were 97% and 94% respectively (p = 0.52). The progression-free survival rate was 68% and 57% respectively (p = 0.35). No deaths occurred within 30 days post-procedure. There were 3 immediate complications in the TIPS group and 4 in the n-TIPS group (p = 1), none of which were related to the TIPS, including thrombosis. CONCLUSION: Percutaneous thermal ablation for HCC in patients with TIPS appears to be as safe and effective as in TIPS-naïve patients. These results suggest that the presence of a TIPS should not be considered a contraindication for percutaneous thermal ablation in treating HCC.

RESUMO

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) has a poor prognosis. The POLO trial showed that olaparib (PARP inhibitor) improved progression-free survival (PFS) but not overall survival (OS), when used as maintenance therapy after ≥ 16 weeks of disease control with first-line platinum-based chemotherapy in patients with germline (g) BRCA 1 or 2 pathogenic variants (PV) metastatic PDAC. However, real-world data on the effectiveness of olaparib are missing. METHODS: Patients with unresectable PDAC associated with somatic (s) or (g)BRCA1/2 and (g)non-BRCA-HRD PV (i.e. other homologous recombination deficiency/HRD genes) who were treated with olaparib between 2020-2023 were included. The primary objective was to describe treatment patterns. Secondary exploratory objectives included OS and PFS in patients treated with olaparib according to the POLO trial or not, OS and PFS in patients with (g)HRD PV-associated PDAC versus (s)PVs, olaparib safety profile and factors associated with olaparib poor outcomes. RESULTS: Among 85 patients, 45.9 % received olaparib as defined by the POLO trial. No difference in OS and PFS was observed between patients who received olaparib according to the POLO trial versus not. Patients with (g)HRD PV-associated PDAC had better OS compared to others (22.3 versus 10.5 months, p = 0.038). Factors associated with olaparib poor outcomes included a high neutrophil-to-lymphocyte ratio and the use of olaparib outside the recommendations of the POLO trial. Few grade ≥ 3 adverse events were reported (9.4 %). CONCLUSION: Patients with (g)HRD PV-associated PDAC had longer OS than those with (s)HRD PV. Olaparib use beyond the scope of the POLO trial was associated with poor outcomes.

RESUMO

BACKGROUNDS: Caregivers are essential in the care of a patient with digestive cancer. Considering their experience and needs is crucial. OBJECTIVES: To explore the experience of caregivers of patients with digestive cancer and to compare the perspectives of patients and caregivers. METHODS: A mixed-methods study with a cross-sectional prospective and a comprehensive qualitative dimension was performed in a medical oncology unit in a French tertiary hospital. Dyads made of patients with digestive cancer and their caregiver were recruited. The Caregiver Reaction Assessment (CRA) and the Supportive Care Needs Survey for Partners and Caregivers (SCNS-PC) questionnaires were distributed to caregivers. The CRA was used to measure the caregiver burden and the SCNS-PC was used to identify the unmet supportive care needs of caregivers. Semi-structured interviews with the dyads were conducted. Qualitative interviews addressed various dimensions of the caregiver's experience from each dyad's member perspective. RESULTS: Thirty-two caregivers completed the questionnaires. Responses showed high self-esteem, schedule burden, and a need for care and information services. Ten dyads participated in the interviews. Three themes emerged from the caregiver's interviews: illness is an upheaval; loneliness and helplessness are experienced; caring is a natural role with positive outcomes. Four themes emerged from patient's interviews: the caregiver naturally assumes the role and gets closer; he is the patient's anchor; his life is disrupted; anxiety and guilt accompany the desire to protect him. In comparing patient and caregiver data, the main theme of disagreement was their relationship. CONCLUSIONS: Caregiver care does not appear to be optimal, particularly in terms of their need for information. Patients have a fairly good representation of their experience, but the caregivers' opinion need to be considered.

RESUMO

The aim of this multicentric study was to prospectively compare 68Ga-DOTANOC PET/CT versus somatostatin receptor scintigraphy (SRS) with SPECT/CT, combined with multiphasic CT scan and MRI in patients with grade 1 or 2 gastroenteropancreatic neuroendocrine tumors (GEP-NET). Patients with histologically proven grade 1 or 2 GEP-NET with suspicion of recurrence or progression, or with typical aspects of GEP-NET on morphological imaging, were explored with conventional imaging (CI): SRS with SPECT/CT, multiphasic CT scan and/or liver MRI followed by 68Ga-DOTANOC PET/CT. The gold standard was based on histology and imaging follow-up. The data of 105 patients (45 woman and 60 men; median age) were analyzed. 68Ga-DOTANOC PET/CT sensitivity was significantly higher than CI sensitivity in per-patient (98.9% vs. 88.6%, p = 0.016) and per-region (97.6% vs. 75.6%, p < 0.001) analyses, in the detection of the primary (97.9% vs. 78.7%; p = 0.016), peritoneal carcinomatosis (95% vs. 30%, p < 0.001), and bone metastases (100% vs. 33.3%, p = 0.041). 68Ga-DOTANOC PET/CT had an impact on the therapeutic management of 41.9% (44/105) patients compared to decisions based on CI explorations. Our data confirm the superiority of 68Ga-DOTANOC PET/CT over CI in the detection of peritoneal carcinomatosis and bone metastasis, as well as its strong therapeutic impact on the management of patients with grade 1-2 GEP-NETs.

RESUMO

BACKGROUND: Prognostic factors of metastatic rectal cancer are not well known. AIM: The objective of this study was to identify prognostic factors of overall survival (OS) in a cohort of patients with non-resectable synchronous metastatic rectal cancer. METHODS: Patients were retrospectively enrolled from 18 French centres. Univariate and multivariate analyses were performed to identify prognostic factors for OS. A simple score was derived from this a development cohort RESULTS: A total of 243 patients with metastatic rectal cancer were included in the study. Median OS was 24.4 months, 95% CI [19.4-27.2]. Among patients with non-resected metastases (n=141), six independent prognostic factors associated with better OS were identified in multivariate analysis: primary tumour surgery, WHO score 0-1, middle or upper rectal tumour, lung metastases only, systemic chemotherapy and targeted agent in first line. A prognostic score individualized three groups, each factor counting for one point in the score (<3, = 3 et > 3). Their median OS were respectively 27.9 months, 95% CI [21.7-35.1], 17.1 months [11.9-19.7] (HR2/1=2.08, 95%, CI [1.31-3.30], p2/1=0.002) and 9.1 months [4.9-11.7] (HR3/2=2.32, 95% CI [1.38-3.92], p3/2=0.001). CONCLUSION: A prognostic score for non-resectable synchronous metastatic rectal cancer can be proposed to classify patients in three prognostic groups.

RESUMO

Background & Aims: Transcatheter arterial chemoembolisation (TACE) is recommended for patients with hepatocellular carcinoma devoid of macrovascular invasion or extrahepatic spread but not eligible for curative therapies. We compared the efficacy and safety of the combination of a single TACE and external conformal radiotherapy (CRT) vs. classical TACE. Methods: TACERTE was an open-labelled, randomised controlled trial with a 1:1 allocation rate to two or three TACE (arm A) or one TACE + CRT (arm B). Participants had a mean age of 70 years, and 86% were male. The aetiology was alcohol in 85%. The primary endpoint was liver progression-free survival (PFS) in the intention-to-treat population. The typical CRT schedule was 54 Gy in 18 sessions of 3 Gy. Results: Of the 120 participants randomised, 64 were in arm A and 56 in arm B; 100 participants underwent the planned schedule and defined the 'per-protocol' group. In intention-to-treat participants, the liver PFS at 12 and 18 months were 59% and 19% in arm A and 61% and 36% in arm B (hazard ratio [HR] 0.69; 95% CI 0.40-1.18; p = 0.17), respectively. In the per-protocol population, treated liver PFS tended to be better in arm B (HR 0.61; 95% CI 0.34-1.06; p = 0.081) than in arm A. Liver-related grade III-IV adverse events were more frequent in arm B than in arm A. Median overall survival reached 30 months (95% CI 23-35) in arm A and 22 months (95% CI 15.7-26.2) in arm B. Conclusions: Although TACE + CRT tended to improve local control, this first Western randomised controlled trial showed that the combined strategy failed to increase PFS or overall survival and led more frequently to liver-related adverse effects. Impact and implications: Hepatocellular carcinoma is frequently treated by arterial embolisation of the tumour and more recently by external radiotherapy. We tried to determine whether combination of the two treatments (irradiation after embolisation) might produce interesting results. Our results in this prospective randomised study were not able to demonstrate a beneficial effect of combining embolisation and irradiation in these patients. On the contrary, we observed more adverse effects with the combined treatment. Clinical Trials Registration: NCT01300143.
