RESUMEN

BACKGROUND: Approximately 10-20% of patients with gastroesophageal adenocarcinoma (GE-ADK) have HER2-positive tumors. The addition of trastuzumab to chemotherapy improves OS in patients with advanced disease. We investigated the effect of perioperative trastuzumab on survival outcomes. METHODS: This French, multicenter, retrospective observational study included HER2-positive GE-ADK patients treated between January 2015 and December 2020. The primary endpoint was DFS at 18 months. Secondary endpoints were pathological complete response rate (pCR), R0 resection rate, OS, and toxicity. RESULTS: Forty-eight patients were included, and they received a median of 6 cycles of preoperative treatment, with grade III/IV adverse events occurring in 23%. Pathologic complete response (pCR) and major pCR according to Mandard system were achieved in 5/48 (10%) and 20/48 (42%) patients, respectively. Loss of HER2 expression was observed in 18/48 (38%) patients. Postoperative complications rate according to the Clavien Dindo classification (≥3) was 37.5%. After a median follow-up of 29 months, the 18-month DFS was 80.4% (95% CI 68.9-93.8) and the 2-year OS rate was 89.0%. Subgroup analysis showed a longer DFS for gastric tumor than gastro-esophageal junction tumor. CONCLUSIONS: This study suggests that perioperative chemotherapy with trastuzumab in patients with HER2-positive GE-ADK is feasible and safe with encouraging survival.

RESUMEN

Background: Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal cancer, and chemotherapy is a key treatment for advanced PDAC. Gemcitabine chemotherapy is still an important component of treatment; however, there is no routine biomarker to predict its efficacy. Predictive tests may help clinicians to decide on the best first-line chemotherapy. Methods: This study is a confirmatory study of a blood-based RNA signature, called the GemciTest. This test measures the expression levels of nine genes using real-time polymerase chain reaction (PCR) processes. Clinical validation was carried out, through a discovery and a validation phases, on 336 patients (mean 68.7 years; range, 37-88 years) for whom blood was collected from two prospective cohorts and two tumor biobanks. These cohorts included previously untreated advanced PDAC patients who received either a gemcitabine- or fluoropyrimidine-based regimen. Results: Gemcitabine-based treated patients with a positive GemciTest (22.9%) had a significantly longer progression-free survival (PFS) {5.3 vs. 2.8 months; hazard ratio (HR) =0.53 [95% confidence interval (CI): 0.31-0.92]; P=0.023} and overall survival (OS) [10.4 vs. 4.8 months; HR =0.49 (95% CI: 0.29-0.85); P=0.0091]. On the contrary, fluoropyrimidine-based treated patients showed no significant difference in PFS and OS using this blood signature. Conclusions: The GemciTest demonstrated that a blood-based RNA signature has the potential to aid in personalized therapy for PDAC, leading to better survival rates for patients receiving a gemcitabine-based first-line treatment.

RESUMEN

BACKGROUND: The optimal treatment strategy after first-line induction therapy in advanced HER2-positive oeso-gastric adenocarcinoma (OGA) remains challenging. METHODS: Patients treated with trastuzumab (T) plus platinum salts and fluoropyrimidine (F) as first-line chemotherapy between 2010 and 2020 for HER2-positive advanced OGA at 17 academic care centers in France, Italy, and Austria were included. The primary objective was the comparison of F + T vs T alone as maintenance regimen in terms of progression-free survival (PFS) and overall survival (OS) after a platinum-based chemotherapy induction + T. As secondary objective, PFS and OS between patients treated with reintroduction of initial chemotherapy or standard second-line chemotherapy at progression were assessed. RESULTS: Among the 157 patients included, 86 (55%) received F + T and 71 (45%) T alone as a maintenance regimen after a median of 4 months of induction chemotherapy. Median PFS from start of maintenance therapy was 5.1 months in both groups (95% CI 4.2-7.7 for F + T and 95% CI 3.7-7.5 for T alone; p = 0.60) and median OS was 15.2 (95% CI 10.9-19.1) and 17.0 months (95% CI 15.5-21.6) for F + T and T alone, respectively (p = 0.40). Of 112/157 patients (71%) receiving systemic therapy after progression under maintenance, 26/112 (23%) were treated with a reintroduction of initial chemotherapy + T and 86/112 (77%) with a standard second-line regimen. Here, median OS was significantly longer with the reintroduction (13.8 (95% CI 12.1-19.9) vs 9.0 months (95% CI 7.1-11.9); p = 0.007) as confirmed by multivariate analysis (HR 0.49; 95% CI 0.28-0.85; p = 0.01). CONCLUSION: No additional benefit of adding F to T monotherapy as a maintenance treatment could be observed. Reintroduction of initial therapy at first progression may be a feasible approach to preserve later treatment lines.

RESUMEN

AIMS: The aim of our study was to assess, with Continuous Glucose Monitoring (CGM), exhaustive information on the glucose profile in people with diabetes starting chemotherapy. We also evaluated the adaptation of glucose-lowering drugs following analysis of CGM recordings. METHODS: Eighty-five people with diabetes starting chemotherapy were included in the ONCODIAB study. A CGM was worn for up to fourteen days in blinded mode before and after the diabetologist's intervention to evaluate the impact of modifying the glucose-lowering drugs. RESULTS: Time spent in range was 67.2 ± 24.2%. Time below the target glucose range (TBR) (< 70 mg/dl) was 8.9% in all the study population. TBR was significantly higher in patients treated with at least one drug due to the risk of hypoglycemia compared to the others (11.5% vs. 4.4%, p = 0.009). Sixty-five patients had available sensor data for the two recordings. Forty-one patients (51.9%) saw a decrease in their antidiabetic treatment after the diabetologist's intervention guided by the first CGM recording. We observed a significant reduction in the time spent below the target glucose range (70-55 mg/dl) between the two CGM recordings (10.3 ± 14.6% vs. 6.3 ± 9.4%, p = 0.016 and 3.8 ± 8.4% vs. 1.2 ± 2.9%, p = 0.012, respectively). CONCLUSIONS: CGM use in blinded mode could be an interesting tool to reduce the risk of hypoglycemia in people with diabetes starting chemotherapy. Our findings fully support the recommendation that assessing hypoglycemia risk should be mandatory in patients with diabetes before starting chemotherapy.

RESUMEN

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.

RESUMEN

BACKGROUND: Small bowel cancer is not a single entity. Population-based studies taking into account histological diversity are scarce. The aim of this study was to report on their trends in incidence by histology in France over the past 20 years. METHODS: All patients with a small bowel cancer diagnosed in 15 French administrative areas covered by a registry from the network of French cancer registries (FRANCIM) were included. Age-standardized incidence rates were estimated using the world standard population. Incidence rates were calculated by gender, age group, histology, and 5-year period. RESULTS: The overall age-standardized incidence rates were 1.46/100,000 inhabitants in men and 0.9/100,000 inhabitants in women. Adenocarcinoma was the most common histological type (38%), followed by neuroendocrine tumors (35%), lymphoma (15%) and sarcoma (12%). Age at diagnosis and tumor location differed between adenocarcinoma and neuroendocrine tumors. The incidence of all four tumor types increased significantly over the 20-year period, with the exception of lymphoma in men. The annual percentage change for neuroendocrine tumors was 3.89% in men and 3.61% in women; for sarcoma, it was 3.38% and 4.08%, respectively. The incidence of adenocarcinoma and lymphoma also increased in women with an annual percentage change of 3.05% and 3.32%, respectively. CONCLUSION: Small bowel cancer incidence has increased over time. This increase occurred with different amplitudes and patterns in the four major histological types. The improvement in imaging techniques could partly explain this increase. It is necessary to determine whether predisposing conditions may contribute to this change.

RESUMEN

PURPOSE: Conditional net survival in recurrence-free patients (CNS-RF) provides relevant clinical information and has never been assessed yet in a non-selected colon cancer population. We aimed to estimate conditional 5-year net survival in recurrence-free patients with colon cancer in the population-based Digestive Cancer Registry of Burgundy (France). METHODS: CNS-RF was estimated in the 3736 patients resected for cure for primary colon cancer between 1976 and 2006, using a flexible parametric model of net survival for every additional year survived at diagnosis and from 1 to 5 years thereafter. RESULTS: The net probability of surviving 5 more years increased from 72% at diagnosis to 92% for recurrence-free patients who survived 5 years after diagnosis. CNS-RF was over 90% 3 years after diagnosis in patients aged 75 and below. CNS-RF was over 95% in patients diagnosed after 2000 who were recurrence-free 3, 4 or 5 years after diagnosis. CNS-RF was similar between patients with stage I and II disease from 2 years after diagnosis and patients with stage III disease from 5 years after diagnosis. The initial differences in net survival related to gross features, clinical presentation, number of harvested nodes in stage II, and number of involved nodes in stage III disappeared after 2 years. CONCLUSIONS: CNS-RF is a relevant measure of prognosis in patients who have already achieved a period of remission. Providing an updated estimation of prognosis in the years following diagnosis may improve the survivors' quality of life and access to credit or insurance.

RESUMEN

BACKGROUND: The optimal treatment for oesophageal cancer is a matter of debate. The aim of this study was to describe patterns of care and survival in a well-defined population for squamous cell carcinoma (SCC) and adenocarcinoma (AC) of the oesophagus. DESIGN: Data were provided by the Digestive Cancer Registry of Burgundy (France). Recurrence, excess mortality and net survival were calculated. RESULTS: Among non-metastatic patients, the proportion of patients resected for cure decreased between 2004 and 2013 from 16% to 9% for SCC and 48% to 22% for AC. The administration of chemoradiation increased from 45 to 53% for SCC and 21 to 30% for AC. A complete clinical response to chemoradiation was reported in 40% of the patients. Five-year net survival did not vary according to histology. It was 55% in the selected group of patients resected for cure, 44% in patients treated with chemoradiation with a complete clinical response. In multivariate analysis, treatment modality only was associated with survival. In metastatic patients, 3-year net survival was 14% for those treated with chemoradiation. CONCLUSION: Chemoradiation has become the most frequently administered treatment. Cancelling or postponing surgery after chemoradiation with complete response should be assessed by a randomized clinical trial.

RESUMEN

Actually, pancreatic cancer is a major challenge in digestive oncology. Its prognosis remains very poor with a five-year net survival less than 10%. Although if pancreatic cancer incidence was low, data from French digestive cancer registries show a dramatic increase in recent years, more marked in women (annual variation of +3.6% between 1982 and 2012) than in men (+2.3%). The currently recognized risk factors like tobacco or obesity cannot explain this evolving epidemiology. Moreover, progress in understanding pancreatic carcinogenesis is still insufficient. Except for familial aggregation, systematic screening couldn't be proposed.

RESUMEN

BACKGROUND: Postoperative mortality after resection of colorectal cancer is an important issue. The aim of this study was to assess early postoperative mortality in a well-defined French population. METHODS: Data on 30- and 90-day postoperative mortality after resection for colorectal cancer were extracted from the digestive cancer registry of Burgundy. Time trends of postoperative mortality between 1989 and 2013 were described for the large population. Case-control studies (death within 30 or 90 days = cases, alive at 90 days = controls) focused on the association between postoperative mortality and surgical approach, obesity and other comorbidities over the last [2010-2013] period, using conditional logistic regressions. RESULTS: Among the 11,448 concerned patients, 30- and 90-day postoperative mortalities were 4.9 and 7.2%. Thirty-day operative mortality decreased from 7.2% (1989-1993) to 4.4% (2010-2013; p < 0.001) for colon cancer and from 4.2 to 3.3% for rectal cancer (NS). Diagnosis before 1997, male gender, advanced age, emergency surgery and palliative resection were associated with a significantly higher 30- and 90-day mortality rate. The univariate risk of mortality was two to three times higher for conventional open laparotomy and conversion than for laparoscopy-assisted surgery. The surgical approach was no longer significant in multivariate analysis. Emergency surgery and comorbidities were associated with higher 30- and 90-day postoperative mortality, whereas obesity was not specific. CONCLUSION: Postoperative mortality after colorectal resection decreased over time. Surgical approach had no influence on early mortality. Improvement in the management of the elderly and patients with comorbidities is a challenge to reduce postoperative mortality in the future.

RESUMEN

Background: Pancreatic cancer is one of the most lethal. Most countries have exhibited a stable or decreasing incidence over time. The aim of this study was to provide updated French temporal trends in pancreatic cancer incidence and mortality over the past three decades. Methods: Incidence was estimated using the French National Network of Cancer Registries (FRANCIM) and mortality using the French Mortality Statistics Office. World age-standardized incidence and mortality were modelled by age-period-cohort models. The net cumulative risk of developing pancreatic cancer by birth cohort was calculated, as were annual percentage changes (APCs) in incidence and mortality. Results: Between 1982 and 2012, age-standardized incidence increased from 4.8 in 1980 to 9.6 per 100 000 in men and from 2.3 to 6.8 in women. The mean APC was 2.3% (2.1-2.6) and 3.6% (3.3-3.9), respectively. The cumulative risk of developing pancreatic cancer before age 75 rose from 0.62% for males born around 1920 to 1.17% for those born around 1950. It was respectively 0.31% and 0.86% for women. Mortality did not vary in men (8.1 per 100 000). It slightly increased in women from 4.0 in 1982 to 5.4 in 2012. Conclusion: Pancreatic cancer incidence and mortality exhibited diverging trends. Incidence increased over the last 30 years in France whereas mortality did not vary in men and moderately increased in women. Incidence remained lower than mortality up to 2002. One cannot exclude the possibility that a similar trend may appear in other countries. Etiological studies are required to further explain this increase.

RESUMEN

BACKGROUND: Little is known about the epidemiology of early gastric cancer (EGC) in Western countries. The aim of this study was to analyze trends in the incidence, management, and survival of EGC in a well-defined population over a 30 year period. METHODS: Data were obtained from the population-based cancer Registry of Burgundy (France). Incidence rates were calculated by sex, age, and 10 year period of diagnosis. Net survival rates were calculated and a multivariate relative survival analysis performed. RESULTS: EGC represented 6.7 % of gastric cancer diagnosed between 1982 and 2011. Age-standardized incidence rates were higher in men (0.79/100,000) than in women (0.40/100,000). Between the periods 1982-1991 and 2002-2011, it decreased from 0.97 to 0.53 per 100,000 in men and from 0.44 to 0.30 per 100,000 in women. Overall, 19 % of the tumors were limited to the mucosa, 69 % to the submucosa, and 15 % invaded lymph nodes. Node invasion and male sex were the only significant prognostic factors. Five-year net survival was 50 % in node-positive patients and 85 % in node-negative patients (p < 0.001). In multivariate analysis, the relative risk of death in men compared to women was 2.3 and was 10.4 in patients with positive nodes compared to patients with negative nodes. CONCLUSIONS: EGCs are rare in France. The prognosis is favorable, except for node-positive cancers, which may benefit from the recently developed adjuvant chemotherapy for gastric cancer.

RESUMEN

The haemoglobin concentration measured by faecal immunochemical tests (FIT) may be decreased in cases of delayed sample return or high temperature. It is an issue of great importance. The aim of this study was to investigate the effects of sample return time and of season on the performance of an FIT (FOB-Gold) with a new buffer. The study included 20 371 participants involved in the French organized colorectal cancer (CRC) screening programme. The probability of a positive screening test, detection rates and positive predictive values for CRC and advanced adenoma were analysed according to sample return time and season of screening. A sample of positive FIT was stored for 7 days in an incubator at 20°C or 30°C. The positivity rate was 4.1% for a sample return time of up to 3 days, 4.1% for 4-5 days and 4.6% for 6-7 days (P=0.25). In multivariate analysis, there was no association between positivity rates, detection rates and positive predictive values for CRC and advanced adenoma and the sample return time or the season of screening. At a constant temperature of 20°C, there was a decrease in the haemoglobin concentration of 5.1% after 7 days. The decrease reached 20.5% at a temperature of 30°C. It was only 4.5% during the first 4 days of storage in the incubator. With the new buffer, delay in sample return or season did not affect the clinical outcome. When temperatures reach 30°C, the faecal sample must be returned promptly.

RESUMEN

Colorectal cancer, incidence has increased by more than 50% over the past 30 years. On the other hand, over the same period, the number of deaths remained stable, which reflects major therapeutic progress. Around 75% of patients may benefit from surgical resection with curative intent. Among them, nearly 30% of stage II and more than 55% of stage III patients present a loco-regional or distant recurrence or a metachronous cancer within 5 years after initial treatment. This high risk of recurrence raises the question of postoperative monitoring in order to detect early recurrences and metachronous cancers at a curable stage. The annual incidence of adenomas is low and the cumulative risk of endoluminal recurrences or metachronous cancer is very low. Therefore intensive endoscopic monitoring is not useful. Postoperative monitoring of distant recurrences is poorly codified. However, despite their limits, recent trials and meta-analysis suggest that survival is increased thanks to clinical monitoring combined with hepatic and pulmonary imaging. CEA measurement usefulness remains debated. A large randomised trial of monitoring strategy ended recently and should provide answers. This report focused on the monitoring mode after curative resection.

RESUMEN

BACKGROUND: Traditionally, survival estimates have been reported as survival from the time of diagnosis. A patient's probability of survival changes according to time elapsed since the diagnosis and this is known as conditional survival. The aim was to estimate 5-year net conditional survival in patients with colorectal cancer in a well-defined French population at yearly intervals up to 5 years. METHODS: Our study included 18,300 colorectal cancers diagnosed between 1976 and 2008 and registered in the population-based digestive cancer registry of Burgundy (France). We calculated conditional 5-year net survival, using the Pohar Perme estimator, for every additional year survived after diagnosis from 1 to 5 years. RESULTS: The initial 5-year net survival estimates varied between 89% for stage I and 9% for advanced stage cancer. The corresponding 5-year net survival for patients alive after 5 years was 95% and 75%. Stage II and III patients who survived 5 years had a similar probability of surviving 5 more years, respectively 87% and 84%. For survivors after the first year following diagnosis, five-year conditional net survival was similar regardless of age class and period of diagnosis. CONCLUSIONS: For colorectal cancer survivors, conditional net survival provides relevant and complementary prognostic information for patients and clinicians.

RESUMEN

BACKGROUND AND AIMS: Data concerning the risk of long-term liver metastasis following surgery of colorectal cancer in the general population are scarce. The 10-year incidence and prognosis of metachronous liver metastases remain unknown. METHODS: Among 4584 patients resected for cure for colorectal cancer recorded in two French digestive population-based cancer registries between 1985 and 2000, 602 presented metastases including liver metastases. RESULTS: The cumulated incidence of liver metastasis was 15% at 5 years and 17% at 10 years, and was mainly related to stage at diagnosis. The 10-year cumulative incidence was 6% for stage I and 30% for stage III. The hazard ratio was 3.2 [2.4-4.3] for stage II and 6.9 [5.1-9.2] for stage III compared with stage I. Among survivors with no recurrence five years after diagnosis, 2.2% developed liver metastasis between 5 and 10 years. Resection for cure of liver metastases was performed in 35% of patients aged under 75 years and in 10% of patients over 75 (P < 0.001). After resection for cure, 10-year relative survival improved from 21% during the period 1985-1997 to 34% during the period 1998-2011 (P = 0.023). Survival in patients with liver metastasis diagnosed between six and 12 months after surgery was less than half that in patients with metastasis diagnosed later (HR: 0.6 [0.4-1.0]). CONCLUSION: Liver metastases from colorectal cancer remain a substantial problem and continue to occur long after five years. This study furnishes unbiased figures that can be used as a reference. Liver metastases that appear late have a better prognosis.

RESUMEN

AIM: To provide trends in incidence, management and survival of cancer of the ampulla of Vater in a well-defined French population. METHODS: Data were obtained from the population-based digestive cancer registry of Burgundy over a 34-year period. Age-standardized incidence rates were computed using the world standard population. Average annual variations in incidence rates were estimated using a poisson regression. A univariate and multivariate relative survival analysis was performed. RESULTS: Age-standardized incidence rates were 0.46 and 0.30 per 100000 inhabitants for men and women, respectively. Incidence rate increased from 0.26 (1976-1984) to 0.58 (2003-2009) for men and remained stable for women. Resection for cure was performed in 48.3% of cases. This proportion was stable over the study period. Among cases with curative resection, pancreatico-duodenectomy was performed in 94.0% of cases and ampullectomy in 6.0% of cases. A total of 50.8% of cancers of the ampulla of Vater were diagnosed at an advanced stage. Their proportion remained stable throughout the study period. The overall 1- and 5-year relative survival rates were 60.2% and 27.7%, respectively. Relative survival did not vary over time. Treatment and stage at diagnosis were the most important determinants of survival. The 5-year relative survival rate was 41.5% after resection for cure, 9.5% after palliative surgery and 6.7% after symptomatic treatment. In multivariate analysis, only stage at diagnosis significantly influenced the risk of death. CONCLUSION: Cancer of the ampulla of Vater is still uncommon, but its incidence increased for men in Burgundy. Diagnosis is often made at an advanced stage, dramatically worsening the prognosis.

RESUMEN

BACKGROUND: Epidemiological data on synchronous and metachronous metastatic colon cancer are scarce. We assessed epidemiological characteristics and survival in synchronous and metachronous metastatic colon cancer in a French population. METHODS: Our study included 932 cases of metastatic colon cancer diagnosed in 1999-2010 and registered in a population-based cancer registry; 758 were synchronous colon metastases and 174 metachronous metastases from resected primary colon cancers diagnosed in 1999-2005. Univariate relative survival was calculated and a multivariate model with proportional hazard applied to net survival by interval was used. RESULTS: Mean age at diagnosis was 71.1 years for patients with metachronous metastasis and 71.4 years for those with synchronous metastasis (p=0.818). Patients with metachronous metastasis were more likely to have R0 resection (Odds Ratio: 3.05 [1.96-4.76], p<0.001) than patients with synchronous metastasis. Five-year relative survival was 7.2% for synchronous metastasis and 17.6% for metachronous metastasis (p<0.001), but did not differ significantly for patients with R0 resection (47.3% and 61.5% respectively, p=0.120). For patients not receiving chemotherapy risk of death was significantly lower in the metachronous metastasis group (Hazard Ratio=0.44 [0.32-0.60], p<0.001). CONCLUSIONS: On a population basis, synchronous metastasis is an independent poor prognostic factor in colon cancer. Chemotherapy and resection of all metastatic sites significantly improved the outcome in patients with synchronous metastasis.
