PREMIUM: A French prospective multicenter observational study of factors impacting on efficacy and compliance to cetuximab treatment in first-line KRAS wild-type metastatic colorectal cancer.

BACKGROUND: Cetuximab improves progression-free survival (PFS) and overall survival (OS) in patients with KRAS wild type (wt) metastatic colorectal cancer (mCRC). Few data are available on factors impacting both efficacy and compliance to cetuximab treatment, which is, in combination with chemotherapy, a standard-of-care first-line treatment regimen for patients with KRAS wt mCRC. PATIENTS AND METHODS: PREMIUM is a prospective, French multicenter, observational study that recruited patients with KRAS wt mCRC scheduled to receive cetuximab, with or without first-line chemotherapy, as part of routine clinical practice, between October 28, 2009 and April 5, 2012 (ClinicalTrials.gov Identifier: NCT01756625). The main endpoints were the factors impacting on efficacy and compliance to cetuximab treatment. Predefined efficacy endpoints were PFS and safety. RESULTS: A total of 493 patients were recruited by 94 physicians. Median follow-up was 12.9 months. Median progression-free survival was 11 months [9.6-12]. In univariate analyses, ECOG performance status (PS), smoking status, primary tumor location, number of metastatic organs, metastasis resectability, surgery, folliculitis, xerosis and paronychia maximum grade, and acne preventive treatment were statistically significant. In multivariate analysis (Hazard Ratios of multivariate stepwise Cox models), ECOG PS, surgery, xerosis and folliculitis were positive prognostics factors for longer PFS. Among all patients, 69 (14%) were non-compliant. In multivariate analysis, no variables were statistically significant. The safety profile of cetuximab was consistent with previous studies. CONCLUSIONS: ECOG PS <2, surgical treatment performed, and maximum grade xerosis or folliculitis developed were predictive factors of cetuximab efficacy on KRAS wt mCRC patients. Unfortunately, we failed in identifying predictive factors for compliance in these patients.

Prognostic and predictive value of the Immunoscore in stage III colon cancer patients treated with oxaliplatin in the prospective IDEA France PRODIGE-GERCOR cohort study.

BACKGROUND: The Immunoscore (IS), which prognostically classifies stage I-III colon cancer (CC) patients, was evaluated in the International Duration Evaluation of Adjuvant Therapy (IDEA) France cohort study investigating 3 versus 6 months of oxaliplatin-based adjuvant chemotherapy in stage III CC patients. PATIENTS AND METHODS: Densities of CD3+ and CD8+ T cells in the tumor and invasive margin were determined by immunohistochemistry, quantified by digital pathology, and converted to IS. Mismatch repair status was determined by immunohistochemistry or by pentaplex PCR. Prediction of disease-free survival (DFS) by IS was analyzed by a multivariable Cox regression model in each study arm. Harrell's C-statistics were used to investigate the IS performance. RESULTS: Samples of 1322 patients were available. IS Low, Intermediate (Int), and High were observed in 43.6%, 47.0%, and 9.4% of patients, respectively. IS Low identified patients at higher risk of relapse or death compared with Int + High [hazard ratio (HR) = 1.54; 95% confidence interval (CI) 1.24-1.93, P = 0.0001]. The 3-year DFS was 66.80% (95% CI 62.23-70.94) for IS Low and 77.14% (95% CI 73.50-80.35) for IS Int + High. In multivariable analysis, IS remained significantly independently associated with DFS (P = 0.003) when adjusted for sex, histological grade, T/N stage, and microsatellite instability. For mFOLFOX6-treated patients (91.6% of the cohort), a statistical significant interaction was observed for the predictive value of IS for treatment duration (3 versus 6 months) in terms of DFS (P = 0.057). IS Int + High significantly predicted benefit of 6 months of treatment (HR = 0.53; 95% CI 0.37-0.75; P = 0.0004), including clinically low- and high-risk stage III CC (all P < 0.001). Conversely, patients with IS Low (46.4%) did not significantly benefit from the 6-month mFOLFOX6 versus the 3-month mFOLFOX6. CONCLUSIONS: The prognostic value of IS for DFS was confirmed in patients with stage III CC treated with oxaliplatin-based chemotherapy. Its predictive value for DFS benefit of longer duration of mFOLFOX6 adjuvant treatment was found in IS Int + High. These results will be validated in an external independent cohort. CLINICALTRIALS.

Geriatric analysis from PRODIGE 20 randomized phase II trial evaluating bevacizumab + chemotherapy versus chemotherapy alone in older patients with untreated metastatic colorectal cancer.

BACKGROUND: Older patients have frailty characteristics that impair the transposition of treatment results found in younger patients. Predictive factors are needed to help with treatment choices for older patients. The PRODIGE 20 study is a randomized phase II study that evaluated chemotherapy associated with bevacizumab (BEV) or not (CT) in patients aged 75 years or older. PATIENTS AND METHODS: Patients underwent a geriatric assessment at randomization and at each evaluation. The predictive value of geriatric and oncologic factors was determined for the primary composite end-point assessing safety and efficacy of treatment (BEV or CT) simultaneously and also progression-free survival (PFS) and overall survival (OS). RESULTS: 102 patients were randomized (51 BEV and 51 CT; median age 80 years [range 75-91]). On multivariate analysis, baseline normal independent activity of daily living (IADL) score and no previous cardiovascular disease predicted the primary end-point. High (versus low) baseline Köhne score predicted short PFS and baseline Spitzer quality of life (QoL) score <8, albumin level ≤35 g/L, CA19.9 >2 LN levels above normal and high baseline Köhne score predicted short OS. Survival without deteriorated QoL and autonomy was similar with BEV and CT. On subgroup analyses, the benefit of bevacizumab seemed to be maintained in patients with baseline impaired IADL or nutritional status. CONCLUSION: Normal IADL score was associated with a good efficacy and safety of both BEV and CT. Köhne criteria may be relevant prognostic factors in older patients. Adding bevacizumab to chemotherapy does not impair patient autonomy or QoL.

Bevacizumab+chemotherapy versus chemotherapy alone in elderly patients with untreated metastatic colorectal cancer: a randomized phase II trial-PRODIGE 20 study results.

Background: Metastatic colorectal cancer frequently occurs in elderly patients. Bevacizumab in combination with front line chemotherapy (CT) is a standard treatment but some concern raised about tolerance of bevacizumab for these patients. The purpose of PRODIGE 20 was to evaluate tolerance and efficacy of bevacizumab according to specific end points in this population. Patients and methods: Patients aged 75 years and over were randomly assigned to bevacizumab + CT (BEV) versus CT. LV5FU2, FOLFOX and FOLFIRI regimen were prescribed according to investigator's choice. The composite co-primary end point, assessed 4 months after randomization, was based on efficacy (tumor control and absence of decrease of the Spitzer QoL index) and safety (absence of severe cardiovascular toxicities and unexpected hospitalization). For each arm, the treatment will be consider as inefficient if 20% or less of the patients met the efficacy criteria and not safe if 40% or less met the safety criteria. Results: About 102 patients were randomized (51 BEV and 51 CT), median age was 80 years (range 75-91). Primary end point was met for efficacy in 50% and 58% and for safety in 61% and 71% of patients in BEV and CT, respectively. Median progression-free survival was 9.7 months in BEV and 7.8 months in CT. Median overall survival was 21.7 months in BEV and 19.8 months in CT. The 36-month overall survival rate was 27% in BEV and 10.1% in CT. Severe toxicities grade 3/4 were mainly non-hematologic toxicities (80.4% in BEV, 63.3% in CT). Conclusion: Bevacizumab combined with CT was safe and efficient. Both arms met the primary safety and efficacy criteria.

Postoperative irinotecan in resected stage II-III rectal cancer: final analysis of the French R98 Intergroup trial†.

BACKGROUD: The R98 trial explores the addition of irinotecan to a 5-fluorouracil (5-FU) plus leucovorin (5-FU/LV) adjuvant regimen in optimally resected stages II-III rectal cancers. We report the updated long-term results. Disease-free survival (DFS) was the primary end point. PATIENST AND METHODS: Between March 1999 and December 2005, 357 patients were randomized: 178 in 5-FU/LV and 179 in LV5-FU2 + irinotecan arm. The trial was stratified by control arm: Mayo Clinic regimen or LV5-FU2 regimen. RESULTS: Three hundred and fifty-seven randomized patients were evaluable for efficacy. With a follow-up of 156 months, the DFS was in favour of experimental arm but did not reach statistical significance [hazard ratio (HR) = 0.80, P = 0.154]. The same was observed for overall survival (OS) (HR = 0.87, P = 0.433). The 5-year DFS was 58% in the control arm and 63% in the experimental arm. The 5-year OS was 74% in the control arm and 75% in the experimental arm. Patients allocated to the experimental arm had more grade 3-4 neutropenia when compared with the LV5-FU2 arm (33% versus 6%, P = 0.03), but not when compared with the Mayo Clinic arm (33% versus 36%, P = 0.84). Grade 3-4 diarrhoea tended to be higher in the experimental arm, but analyses stratified by control arm or by radiotherapy failed to show significant differences across strata (test for interaction P = 0.44). CONCLUSION: Even though a benefit of irinotecan in subgroups of patients cannot be excluded, due to early termination and lack of power, the study does not support the addition of irinotecan to 5-FU/LV in routine in patients with resected stage II-III rectal cancer.

FOLFOX4 versus sequential dose-dense FOLFOX7 followed by FOLFIRI in patients with resectable metastatic colorectal cancer (MIROX): a pragmatic approach to chemotherapy timing with perioperative or postoperative chemotherapy from an open-label, randomized phase III trial.

BACKGROUND: Perioperative FOLFOX4 (oxaliplatin plus 5-fluorouracil/leucovorin) chemotherapy is the current standard in patients with resectable metastases from colorectal cancer (CRC). We aimed to determine whether a sequential chemotherapy with dose-dense oxaliplatin (FOLFOX7) and irinotecan (FOLFIRI; irinotecan plus 5-fluorouracil/leucovorin) is superior to FOLFOX4. The chemotherapy timing was not imposed, and was perioperative or postoperative. PATIENTS AND METHODS: In this open-label, phase III trial, patients with resectable or resected metastases were randomly assigned either to 12 cycles of FOLFOX4 (oxaliplatin 85 mg/m(2)) or 6 cycles of FOLFOX7 (oxaliplatin 130 mg/m(2)) followed by 6 cycles of FOLFIRI (irinotecan 180 mg/m(2)). Randomization was done centrally, with stratification by chemotherapy timing, type of local treatment (surgery versus radiofrequency ablation with/without surgery), and Fong's prognostic score. The primary end point was 2-year disease-free survival (DFS). RESULTS: A total of 284 patients were randomized, 142 in each treatment group. Chemotherapy was perioperative in 168 (59.2%) patients and postoperative in 116 (40.8%) patients. Perioperative chemotherapy was preferentially proposed for synchronous metastases, whereas postoperative chemotherapy was more frequently used for metachronous metastases. Two-year DFS was 48.5% in the FOLFOX4 group and 50.0% in the FOLFOX7-FOLFIRI group. In the multivariable analysis, more than one metastasis [hazard ratio (HR) = 2.15] and synchronous metastases (HR = 1.63) were independent prognostic factors for shorter DFS. Five-year overall survival (OS) rate was 69.5% with FOLFOX4 versus 66.6% with FOLFOX7-FOLFIRI. CONCLUSIONS: FOLFOX7-FOLFIRI is not superior to FOLFOX4 in patients with resectable metastatic CRC. Five-year OS rates observed in both groups are the highest ever reported in this setting, possibly reflecting the pragmatic approach to chemotherapy timing. CLINICAL TRIALS NUMBER: NCT00268398.

Evaluation in usual practice of the bevacizumab-FOLFIRI combination for the first-line treatment of patients with unresectable metastatic colorectal cancer treated in 2006: focus on resected patients and oncogeriatrics: AVASTIN OUEST cohort of the Observatory of Cancer of the Brittany and Pays de la Loire Areas (Observatoire dédié au Cancer Bretagne / Pays de la Loire).

BACKGROUND: In 2006, bevacizumab, a targeted therapy agent was combined with FOLFIRI for the firstline treatment of patients with unresectable metastatic colorectal cancer. METHODS/RESULTS: A study on a homogenous series of 111 patients from the Brittany and Pays de la Loire areas who received bevacizumab-FOLFIRI as first-line treatment in 2006 showed the following results: 51 responses, 29 stabilisations, 21 progressions and 10 cases of toxicity prior to assessment. Median overall survival (OS) was 25.1 months and median progression-free survival was 10.2 months. Surgery secondary to treatment tripled median OS which reached 59.2 months in resected patients versus 18.8 months in unresected patients. Comparison of patients aged more or less than 70 years showed no differences in terms of benefits or risks. CONCLUSION: Bevacizumab-FOLFIRI could be administered as part of a routine care protocol to elderly patients previously evaluated by a geriatric assessment and validated by a multidisciplinary staff.

En 2006, bevacizumab-FOLFIRI représente la thérapie ciblée administrable dès la première ligne chez les patients porteurs d'un cancer colorectal métastatique non opérable. Une série homogène de 111 patients colligés en région Bretagne et Pays de la Loire ayant reçu du bevacizumab- FOLFIRI en première ligne en 2006 révèle les résultats suivants: 51 réponses, 29 stabilités, 21 progressions et 10 toxicités avant évaluation. La médiane de survie globale (OS) est de 25,1 mois et la médiane de survie sans progression (PFS) de 10,2 mois. Dans le cas d'une chirurgie secondaire, l'OS médian triple de 18,8 mois chez les patients non réséqués versus 59,2 mois ceux réséqués. En comparant les sujets âgés de plus et de moins de 70 ans, aucune différence n'a été mise en évidence en termes de bénéfice ou de risque. Bevacizumab-FOLFIRI pourrait être administré en pratique courante chez les personnes âgées sous couvert d'une évaluation gériatrique et d'une approche multidisciplinaire.

Epidemiological and prognostic factors involved in upper gastrointestinal bleeding: results of a French prospective multicenter study.

BACKGROUND AND STUDY AIMS: The mortality rate from upper gastrointestinal bleeding (UGIB) remains high, at 5 % - 10 %. The aim of the current study was to describe the epidemiological characteristics, prognostic factors, and actual practice in a cohort of patients with UGIB admitted to French general hospitals. METHODS: From March 2005 to February 2006, a prospective multicenter study was conducted at 53 French hospitals. A total of 3298 patients admitted for UGIB were enrolled consecutively. Patient data were collected up to the date of discharge from hospital. RESULTS: Data were available for 2130 men and 1073 women (mean age 63 ± 18 years), one-third of whom were taking drugs that would increase the risk of UGIB. The two main causes of bleeding were peptic ulcers (38 %) and esophagogastric varices (EGV) or portal hypertensive gastropathy (24.5 %). Mean Rockall score was 5.0 ± 2.3. Endoscopy was performed on 96 % of patients (within 24 hours in 79 %), and 66 % of those with ulcers and 62.5 % of the EGV patients underwent hemostatic therapy when indicated. Rebleeding occurred in 9.9 % of the patients, and 8.3 % died. Independent predictors of rebleeding were: need for transfusion (odds ratio [OR] 19.1; 95 % confidence interval [95 %CI] 10.1 - 35.9); hemoglobin < 10 g/dL (OR: 1.7; 95 %CI 1.1 - 3.3); Rockall score (OR: 1.4 for each 1 point score increase; 95 %CI 1.0 - 1.9), systolic blood pressure < 100 mmHg (OR: 1.9; 95 %CI 1.4 - 2.5), and signs of recent bleeding (OR: 2.4; 95 %CI 1.7 - 3.5). Independent predictors of mortality were: Rockall score (OR: 2.8; 95 %CI 2.0 - 4.0), co-morbidities (OR: 3.6 for each additional co-morbidity; 95 %CI 2.0 - 6.3), and systolic blood pressure < 100 mmHg (OR: 2.1; 95 %CI 1.8 - 2.8). Rockall score, blood pressure and co-morbidities were taken as continuous variables meaning that the OR was 1.4 for every point increase, it was the same for blood pressure. CONCLUSION: UGIB still occurs mainly as a result of peptic ulcers and portal hypertension in France, and causes significant rates of mortality. There is scope for improvement via better prevention (better use of UGIB-facilitating drugs), endoscopic therapy, and management of co-morbidities.

Cost-minimisation analysis in first-line treatment of metastatic colorectal cancer in France: XELOX versus FOLFOX-6.

OBJECTIVE: In a recent randomized study, we demonstrated that XELOX (oxaliplatin + oral capecitabine) was well tolerated and not inferior in terms of efficacy to the infusional FOLFOX-6 regimen in first-line treatment of metastatic colorectal cancer (mCRC). The objective of this additional analysis was to compare the cost of XELOX and FOLFOX-6. METHODS: This cost-minimisation study took into account costs related to drug acquisition, hospital care for chemotherapy administration and for serious adverse event management. Hospital care costs were based on French 'diagnosis-related group' tariffs. Drug acquisition costs were drawn from French official sources. Analysis was performed from the French health insurance perspective. RESULTS: Baseline characteristics of the 282 patients included (143 XELOX, 139 FOLFOX-6) were well balanced. Patients reported less and shorter hospitalisations (day and overnight hospital care) with XELOX: 6.4 ± 2.2 hospitalisations versus 9.7 ± 3.1 (p < 0.001); 11.4 ± 10.6 days versus 17.7 ± 11.8 (p < 0.001). Mean disease management cost per patient was significantly lower with XELOX (EUR 12,918 ± 5,075 vs. EUR 17,229 ± 8,665, p < 0.001). CONCLUSION: In the perspective of our analysis, taking into account hospitalisation and drug acquisition costs, the treatment of mCRC patients with XELOX in comparison to FOLFOX-6 significantly decreased the costs, as well as the mean overall hospitalisation length of stay.

Quality-of-life findings from a randomised phase-III study of XELOX vs FOLFOX-6 in metastatic colorectal cancer.

BACKGROUND: A phase-III trial showed the non-inferiority of oral capecitabine plus oxaliplatin (XELOX) vs 5-fluorouracil/leucovorin plus oxaliplatin (FOLFOX-6) in terms of efficacy in first-line treatment of metastatic colorectal cancer. A secondary objective was to compare the quality of life (QoL) and health-care satisfaction of patients. METHODS: Patients were randomised to receive XELOX (n=156) or FOLFOX-6 (n=150) for 6 months. Quality of life and satisfaction were assessed by the Quality of Life Questionnaire-C30 (QLQ-C30) and Functional Assessment of Chronic Illness Therapy Chemotherapy Convenience and Satisfaction Questionnaire (FACIT-CCSQ), respectively. Patients completed questionnaires at baseline, at Cycle3 (C3) and Cycle (C6) (XELOX) or at C4 and C8 visits (FOLFOX-6) and at their final visit. RESULTS: A total of 245 and 225 patients were assessed using QLQ-C30 and FACIT-CCSQ, respectively. The completion rates were >80%. Global QoL scores did not differ significantly between groups during the study. According to FACIT-CCSQ, XELOX seemed more convenient (C3/C4, P<0.001; C6/C8, P=0.009) and satisfactory to patients (C6/C8, P=0.003) than FOLFOX-6. At the final visit, XELOX patients spent fewer days on hospital visits (3.3 vs 5.3 days, P=0.045) and lost fewer hours of work/daily activities (10.2 vs 37.1 h lost, P=0.007). CONCLUSION: XELOX has a similar QoL profile, but seemed to be more convenient in terms of administration at certain time points and reduced time lost for work or other activities compared with FOLFOX-6.

Phase II study of UFT with leucovorin and irinotecan (TEGAFIRI): first-line therapy for metastatic colorectal cancer.

This phase II trial was performed to evaluate the efficacy and tolerability of oral tegafur-uracil (UFT) with leucovorin (LV) combined with intravenous (i.v.) irinotecan every 3 weeks (TEGAFIRI) as first-line treatment for patients with metastatic colorectal cancer (mCRC). Patients received oral UFT 250 mg m(-2) day(-1) and LV 90 mg day(-1) in three divided daily doses for 14 days followed by a 1-week rest and i.v. irinotecan 250 mg m(-2) as a 90-min infusion every 3 weeks. Tumour responses, assessed every two cycles using RECIST criteria, were reviewed by an independent review committee. In 52 evaluable patients, the best overall response rate was 33% (95% confidence intervals (CI) 20-47%; 1 complete and 16 partial responses). The median time to progression was 5.4 months (95% CI 3.02-7.52 months) and median overall survival was 14.9 months (11.73-17.97 months). A total of 307 cycles were administered, with a median number of five cycles per patient (range: 1-10). The most common grade 3/4 toxicities were neutropenia (25% of patients), diarrhoea (22%), vomiting (11%) and anaemia (11%). The TEGAFIRI regimen is a feasible, well-tolerated and convenient treatment option for patients with non-resectable mCRC.

Gemcitabine in combination with oxaliplatin compared with gemcitabine alone in locally advanced or metastatic pancreatic cancer: results of a GERCOR and GISCAD phase III trial.

PURPOSE: Gemcitabine (Gem) is the standard treatment for advanced pancreatic cancer. Given the promising phase II results obtained with the Gem-oxaliplatin (GemOx) combination, we conducted a phase III study comparing GemOx with Gem alone in advanced pancreatic cancer. PATIENTS AND METHODS: Patients with advanced pancreatic cancer were stratified according to center, performance status, and type of disease (locally advanced v metastatic) and randomly assigned to either GemOx (gemcitabine 1 g/m2 as a 100-minute infusion on day 1 and oxaliplatin 100 mg/m2 as a 2-hour infusion on day 2 every 2 weeks) or Gem (gemcitabine 1 g/m2 as a weekly 30-minute infusion). RESULTS: Three hundred twenty-six patients were enrolled; 313 were eligible, and 157 and 156 were allocated to the GemOx and Gem arms, respectively. GemOx was superior to Gem in terms of response rate (26.8% v 17.3%, respectively; P = .04), progression-free survival (5.8 v 3.7 months, respectively; P = .04), and clinical benefit (38.2% v 26.9%, respectively; P = .03). Median overall survival (OS) for GemOx and Gem was 9.0 and 7.1 months, respectively (P = .13). GemOx was well tolerated overall, although a higher incidence of National Cancer Institute Common Toxicity Criteria grade 3 and 4 toxicity per patient was observed for platelets (14.0% for GemOx v 3.2% for Gem), vomiting (8.9% for GemOx v 3.2% for Gem), and neurosensory symptoms (19.1% for GemOx v 0% for Gem). CONCLUSION: These results confirm the efficacy and safety of GemOx, but this study failed to demonstrate a statistically significant advantage in terms of OS compared with Gem. Because GemOx is the first combined treatment to be superior to Gem alone in terms of clinical benefit, this promising regimen deserves further development.

[Multicenter prospective study of prognostic factors of gastroduodenal ulcer hemorrhages. Reevaluation of clinical and endoscopic factors in the era of endoscopic hemostasis]. / Etude prospective multicentrique des facteurs pronostiques des hémorragies ulcéreuses gastroduodénales. Réévaluation des facteurs cliniques et endoscopiques à l'ère de l'hémostase endoscopique.

AIM: To evaluate in a prospective study the prognostic factors of recurrent bleeding and mortality in patients presenting with high risk peptic ulcer bleeding routinely treated by endoscopic hemostasis. PATIENTS AND METHODS: A multicenter study was carried out in 8 Western French hospitals in 144 patients with gastrointestinal bleeding peptic from ulcer type I or IIa, b as defined by Forrest classification. Thirty four and 38 parameters were studied respectively in order to predict recurrent bleeding and death. Significant predictive factors (P < 0.1) in univariate analysis were entered in a multivariate logistic regression analysis. RESULTS: Endoscopic hemostasis was performed in 108 of 144 cases (75%). Recurrent bleeding and death occurred in 39 (28%) and 22 cases (15%), respectively. By multivariate analysis, the only predictor of rebleeding was hypovolemia at admission. Predictors of death were ASA score, cardiovascular Goldman score and recurrent bleeding. In this study, prevalence of Helicobacter pylori infection was low (41%) but was not a predictive factor. CONCLUSIONS: In a selected population of peptic ulcer bleeding patients with high risk of rebleeding, prevalence of recurrent bleeding and death remains rather high, despite routine endoscopic hemostasis. In the era of endoscopic hemostasis, clinical parameters remain the best prognostic factors of peptic ulcer bleeding outcome.

[Black esophagus. Three new cases]. / L'oesophage noir. Trois nouveaux cas.

We report three cases of "black esophagus" defined as a diffuse or patchy black color of the esophagus on endoscopy, associated with mucosa necrosis at histologic examination. Ischemia was invocated in two cases and alcaline reflux seemed to be likely in the third case. These observations are compared with the seven others cases previously reported in the literature.

[Surgical treatment of chronic pancreatitis. Indications and results. An experience of 246 cases]. / Traitement chirurgical de la pancréatite chronique. Indications et résultats--Expérience de 246 cas.

Between 1972 and 1986, 246 patients, mainly alcoholic, with a mean age of 44 years, underwent a total of 270 laparotomies. Parenchymal resections were carried out in 99 patients and drainage and diversion procedures were carried out in 159. Pain was the principal symptom and led to surgery in 60% of cases; biliary or duodenal obstruction was present in 40 and 23.5% of cases respectively. Operative mortality was 9% for resections and 5.8% for other forms of surgery. In the long term, the best results were obtained in patients in whom a Whipple procedure was performed.

Hepatic artery injection of I-131-labeled lipiodol. Part II. Preliminary results of therapeutic use in patients with hepatocellular carcinoma and liver metastases.

Internal radiation therapy with transarterial injection of iodine-131-labeled iodized oil (Lipiodol Ultra-Fluide [LUF]) was evaluated in 15 patients with hepatocellular carcinoma and eight with hepatic metastases. Five patients with hepatocellular carcinoma received more than one injection. Treatment tolerance was excellent, as assessed clinically and by means of liver function tests. An analgesic effect was noted in the two patients with painful hepatocellular carcinomas. Serum alpha 1-fetoprotein levels dropped rapidly in 11 of the 12 patients with elevated basal values. An average reduction in tumor size of 50% was observed in the nine cases followed up with computed tomography. After 5-12 months of follow-up, six of the 15 patients with hepatocellular carcinoma were alive. Two of them had undergone liver transplantation. Histologic examination of one of the livers, removed 3 months after a third injection, revealed microscopic features highly suggestive of radiation effect in LUF-containing areas. In the group with widespread hepatic metastases, no objective response was noted, except for an analgesic effect in three cases.
