Predictive factors of depressive symptoms of elderly patients with cancer receiving first-line chemotherapy.

BACKGROUND: Depression is the most common psychiatric disorder in geriatrics and oncology. For elderly cancer patients, it has a significant impact on quality of life, morbidity, and mortality. Nevertheless, depression is under-diagnosed and under-treated. Cancer management is key in improving the quality of care in this population. We aim to identify sociodemographic, clinical, and treatment-related factors of depression in elderly patients during chemotherapy, thus allowing early detection of patients in need of specific treatment. Further, we investigate whether chemotherapy efficacy and safety are associated with depression. PATIENTS AND METHODS: A prospective multicenter cohort composed of incident cases of cancer diagnosed in patients 70 years and older, receiving first-line chemotherapy. Depressive symptoms were measured by the Geriatric Depression Scale at baseline and after four chemotherapy cycles. Associations between depressive symptoms during chemotherapy and patients' clinical and treatment characteristics were identified by logistic regression. RESULTS: Among 344 patients measured for depression before chemotherapy, 260 had a second assessment at the fourth treatment cycle. At baseline, 45.4% were depressed, and 44.6% were depressed after the fourth cycle. Independent factors of depression were depressive symptoms at baseline (odds ratio (OR) = 6.7, p < 0.001), malnutrition (OR = 5.1, p = 0.014), and risk of malnutrition (OR = 1.6, p = 0.014). After controlling for missing data, effective chemotherapy was associated with a lower risk of depression (OR = 0.4, p = 0.018). CONCLUSION: We highlight the role of depressive symptoms and nutritional status at baseline, on the occurrence of depressive symptoms during chemotherapy. These factors should be taken into account in any pre-treatment consultation and appropriate nutritional and psychiatric preventative measures established. Copyright © 2016 John Wiley & Sons, Ltd.

Radiofrequency ablation is a valid treatment option for lung metastases: experience in 566 patients with 1037 metastases.

BACKGROUND: Minimal invasive methods are needed as an alternative to surgery for treatment of lung metastases. PATIENTS AND METHODS: The prospective database of two cancer centers including all consecutive patients treated with radiofrequency ablation (RFA) for lung metastasis over 8 years was reviewed. RFA was carried out under general anesthesia, with computed tomography guidance using a 15-gauge multitined expandable electrodes RF needle. RESULTS: Five hundred sixty-six patients including 290 men (51%), 62.7 ± 13.2 years old with primary tumor to the colon (34%), rectum (18%), kidney (12%), soft tissue (9%) and miscellaneous (27%) received 642 RFA for 1037 lung metastases. Fifty-three percent of patients had 1 metastasis, 25% had 2, 14% had 3, 5% had 4 and 4% had 5-8. Metastases were unilateral (75%), or bilateral (25%). The median diameter [extremes] of metastases was 15 mm (4-70). Twenty-two percent of patients had extrapulmonary disease amenable to local therapy including 49 liver, 16 bone and 60 miscellaneous metastases. Median follow-up was 35.5 months. Median overall survival (OS) was 62 months. Four-year local efficacy was 89%. Four-year lung disease control rate was 44.1%, with patient retreated safely up to four times. Primary origin, disease-free interval, size and number of metastases were associated with OS in multivariate analysis. Progression at RFA site was associated with poor OS [P = 0.011, hazard ratio (HR): 1.69 (95% confidence interval 1.13-2.54)]. In the 293 colorectal cancer metastases, size >2 cm (HR = 2.10, P = 0.0027) and a number of metastases ≥3 (HR = 1.86, P = 0.011) remained significantly associated with OS. A prognostic score made of three groups based on the four above-mentioned prognostic factors demonstrated 3-year OS rates of respectively 82.2%, 69.5% and 53.6% (log-rank test, P ≤ 0.0001) among the three groups in the overall population, and of 81.3%, 72.8% and 57.9% (log-rank test, P = 0.005) in the colorectal cancer patients. CONCLUSION: Radiofrequency is an option for treatment of small size lung metastases, namely the ones below 2-3 cm.

[Mediastinal sarcoidosis in an oncologic context: role of endoscopic ultrasound-guided fine needle aspiration]. / Sarcoïdose médiastinale dans un contexte oncologique : apport de la ponction aspiration guidée par échoendoscopie.

INTRODUCTION: Sarcoidosis and sarcoid reactions have been previously reported in association with cancer. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is a minimally invasive test for investigating mediastinal lymph nodes PATIENTS AND METHODS: We conducted a retrospective review of 54 patients undergoing EUS-FNA in a cancer institute for suspected metastatic mediastinal lymph nodes showed by CT-imaging or positron emission tomography (PET). Patients with non-caseating granuloma identified by EUS-FNA were included RESULTS: EUS-FNA identified non-caseating granuloma in seven out of the 54 included patients. Most of them had positive PET. One patient had a prior history of sarcoidosis before the diagnosis of cancer. Another patient developed micrometastasis associated with sarcoid-like reaction. There was no adverse outcome associated with the EUS-FNA procedure CONCLUSIONS: Sarcoidosis must be included in the differential diagnosis of patients with a history of malignancy who develop mediastinal lymphadenopathy. EUS-FNA is a safe and minimally invasive test to obtain tissue diagnosis.

Screening older cancer patients: first evaluation of the G-8 geriatric screening tool.

BACKGROUND: Development of a geriatric screening tool is necessary to identify elderly cancer patients who would benefit from comprehensive geriatric assessment (CGA). We develop and evaluate the G-8 screening tool against various reference tests. PATIENTS AND METHODS: Analyses were based on 364 cancer patients aged>70 years scheduled to receive first-line chemotherapy included in a multicenter prospective study. The G-8 consists of seven items from the Mini Nutritional Assessment (MNA) questionnaire and age. Our primary reference test is based on a set of seven CGA scales: Activities Daily Living (ADL), Instrumental ADL, MNA, Mini-Mental State Exam, Geriatric Depression Scale, Cumulative Illness Rating Scale-Geriatrics, and Timed Get Up and Go. We considered the presence of at least one questionnaire with an impaired score as an abnormal reference exam. Additional reference exams are also discussed. RESULTS: The prevalence of being at risk varied from 60% to 94% according to the various definitions of the reference test. When considering the primary reference test, a cut-off value of 14 for the G-8 tool provided a good sensitivity estimate (85%) without deteriorating the specificity excessively (65%). CONCLUSION: The G-8 shows good screening properties for identifying elderly cancer patients who could benefit from CGA.

[Radiofrequency ablation in the treatment of liver and lung tumors]. / Traitement par radiofréquence des tumeurs hépatiques et pulmonaires.

Radiofrequency (RF) ablation is a technique of thermotherapy which emerged over the last fifteen years in the field of oncology. RF directed toward a specific tumor mass is known to be very effective (over 90%) for treating tumors less than 2.5 cm. RF is used for patients with early-stage lung or liver cancers who are not surgical candidates, With improvements in systemic therapy, increasing interest in the use of local therapy for metastases has arisen. Eradication of residual metastases via local therapies has a sense in patients with stabilized disease. Nonsurgical alternative like RF has become popular because it is less invasive than surgery and has demonstrated great efficiency. Nevertheless prospective randomized trials to compare RF with surgery are difficult to achieve, prospective studies are needed to better evaluate the technique.

Pharmacokinetic and pharmacogenetic determinants of the activity and toxicity of irinotecan in metastatic colorectal cancer patients.

This study aims at establishing relationships between genetic and non-genetic factors of variation of the pharmacokinetics of irinotecan and its metabolites; and also at establishing relationships between the pharmacokinetic or metabolic parameters and the efficacy and toxicity of irinotecan. We included 49 patients treated for metastatic colorectal cancer with a combination of 5-fluorouracil and irinotecan; a polymorphism in the UGT1A1 gene (TA repeat in the TATA box) and one in the CES2 gene promoter (830C>G) were studied as potential markers for SN-38 glucuronidation and irinotecan activation, respectively; and the potential activity of CYP3A4 was estimated from cortisol biotransformation into 6beta-hydroxycortisol. No pharmacokinetic parameter was directly predictive of clinical outcome or toxicity. The AUCs of three important metabolites of irinotecan, SN-38, SN-38 glucuronide and APC, were tentatively correlated with patients' pretreatment biological parameters related to drug metabolism (plasma creatinine, bilirubin and liver enzymes, and blood leukocytes). SN-38 AUC was significantly correlated with blood leukocytes number and SN-38G AUC was significantly correlated with plasma creatinine, whereas APC AUC was significantly correlated with plasma liver enzymes. The relative extent of irinotecan activation was inversely correlated with SN-38 glucuronidation. The TATA box polymorphism of UGT1A1 was significantly associated with plasma bilirubin levels and behaved as a significant predictor for neutropoenia. The level of cortisol 6beta-hydroxylation predicted for the occurrence of diarrhoea. All these observations may improve the routine use of irinotecan in colorectal cancer patients. UGT1A1 genotyping plus cortisol 6beta-hydroxylation determination could help to determine the optimal dose of irinotecan.

Comparison of hepatic recurrences after resection or intraoperative radiofrequency ablation indicated by size and topographical characteristics of the metastases.

AIMS: Intraoperative use of radiofrequency ablation (IRFA) to treat liver metastases is controversial. The aim of this study was to compare local recurrence rate and survival after IRFA versus resection. METHODS: Three groups from 99 patients were consecutively operated on for 307 liver metastases with 2years of follow up: group 1, IRFA alone (n=34); group 2, IRFA plus resection (n=28); group 3, resection alone (n=37). The choice of IRFA or resection was made on the basis of the sizes and topographies of the metastases with the goal of achieving R0 treatment. RESULTS: Mortality was zero; morbidity was 9%, 11% and 11% in the three groups respectively. Median follow-up after surgery was 30months. Total hepatic recurrences occurred in 59 (60%) patients. Median survival without hepatic recurrence was 17months with no difference between the three groups (P=0.474). Total local recurrence occurred in 4 (12%) patients in group 1, in 2 (8%) patients in group 2, and in 2 (6%) patients in group 3. Survival at 2years was no different in the three groups. CONCLUSION: Assessing IRFA indications by size and the topographical characteristics of the liver metastases yields identical local recurrence rates to resection after 2years of follow up.

Surgical treatment of liver metastases by radiofrequency ablation, resection, or in combination.

AIMS: Radiofrequency ablation (RFA) has a role in the treatment of unresectable liver metastases either percutaneously or in open surgery. The aim of this study was to determine the feasibility and value using RFA, resection or in combination to cure liver metastases of colorectal or other origin. METHODS: Fifty-two consecutive patients were operated on with the intention to treat their liver metastases using both techniques of RFA and resection in the same curative intent. A CT scan was performed 2 months postoperatively and then every 4 months. RESULTS: Fifty patients with 137 metastases could be treated: 55 lesions were resected and 82 were ablated. Curative treatment of 13 patients could only be achieved by using RFA combined with resection. Morbidity was 16% and local treatment proved insufficient in three cases. Estimated 1-year survival probabilities were, respectively, 0.85 in the colorectal group and 0.80 in the non-colorectal group. CONCLUSIONS: RFA increased resectability of liver metastases and reduced the morbidity. Respective indications of both techniques were complementary and depend on the size and the topography of the lesion to be treated.

Phase II trial of bimonthly leucovorin, 5-fluorouracil and gemcitabine for advanced pancreatic adenocarcinoma (FOLFUGEM).

BACKGROUND: Gemcitabine alone or 5-fluorouracil (5-FU) according to several schedules are used for palliation of metastatic and locally advanced (LA) pancreatic adenocarcinoma. This study was designed to test the efficacy of the leucovorin 5-FU and gemcitabine combination. PATIENTS AND METHODS: This phase II trial combined a simplified bimonthly LV5FU2 with gemcitabine: leucovorin 400 mg/m2 in a two-hour infusion, followed by 5-fluorouracil 400 mg/m2 bolus and 2 or 3 g/m2 continuous infusion over 46 hours; gemcitabine 1 g/m2 was infused over 30 min on day 3 after 5-FU. Treatment was repeated every two weeks. Gemcitabine dose could be increased (250 mg/m2 every two cycles up to 1500 mg/m2) in the absence of NCI-CTC toxicity > 2. RESULTS: Among the 62 patients included in this study, 22 had LA and 40 had metastatic disease. Objective response rate for the 54 patients with measurable disease was 25.9% (95% confidence interval (CI): 14%-37.8%) and 22.6% (95% CI: 12%-33.2%) in the intent-to-treat population: the clinical benefit rate for the 59 assessable patients was 49.2%. Median progression-free survival and median overall survival were 4.8 and 9 months, respectively, with 32.3% of patients alive at 1 year. The most frequent toxicity (grade 3-4) was neutropenia (56.5%) usually asymptomatic (1.1% febrile neutropenia), but requiring decreases of 5-FU and gemcitabine doses. Unexpected complete alopecia occurred in 97% of patients. CONCLUSIONS: Palliative effects, response rate and survival observed in this multicenter study seem to be superior to those obtained with gemcitabine or 5-FU alone, despite a limiting hematological toxicity.

[Contribution of gemcitabine in the treatment of advanced pancreatic cancer]. / Apport de la gemcitabine dans le traitement du cancer du pancréas avancé.

INTRODUCTION: Pancreatic cancer is one of the most common tumor of the gastrointestinal tract. CURRENT KNOWLEDGE AND KEY POINTS: Because this malignancy is usually diagnosed at an advanced stage, its prognosis is poor, and patients are generally considered incurable at diagnosis. The traditional palliative approach to management of this tumor is chemotherapy. The most widely used agent is 5-FU, alone or in combination. Benefits of the treatment are still poor: the overall survival time rarely exceeds 5 months, and no study has shown a response rate greater than 20%. FUTURE PROSPECTS AND PROJECTS: Gemcitabine, a new antinucleoside agent, has led to promising results, as several phase II and III studies have demonstrated an increase in survival as compared with 5-FU, the overall 1-year survival rates being 18% and 2%, respectively (p < 0.002). Furthermore, even if only discrete results in terms of objective response rate have been achieved, gemcitabine decreases disease-related symptoms, thus benefiting to the patient's quality of life. The concept of clinical benefit therefore appears to be an important judgement criteria in the assessment of chemotherapy efficacy, and will certainly be extended to other malignant neoplasms.

Treatment of hepatitis C virus-related cirrhosis: a randomized, controlled trial of interferon alfa-2b versus no treatment.

To examine the effects of interferon (IFN) therapy on clinical, biochemical, and histological features in patients with compensated hepatitis C virus (HCV)-related cirrhosis, we have conducted a randomized, controlled trial of IFN therapy versus observation. Eight centers included a total of 99 patients with biopsy-proven cirrhosis. IFN-alpha2b, 3 million units three times per week, or no antiviral therapy was given for 48 weeks. Twenty-three patients dropped out. End-of-treatment biochemical response was not observed in any of the 39 controls but was observed in 6 of the 47 treated patients (P <.02); sustained biochemical response was obtained in only 2 treated patients. Controls and treated patients did not significantly differ with regard to the changes in serum level of albumin, bilirubin, alpha-fetoprotein, in plasma prothrombin, in histological activity, or liver collagen content. During trial or follow-up (160 +/- 57 weeks), hepatocellular carcinoma developed in 9 controls and 5 treated patients (NS); decompensation of cirrhosis occurred in 5 controls and 7 treated patients. Seven controls and 10 treated patients died. In conclusion, in patients with compensated HCV-related cirrhosis, a 48-week course of IFN therapy is safe and is able to induce end-of-treatment biochemical response in a significant proportion of patients. However, a 48-week course of IFN therapy usually fails to achieve sustained response and, within the limit of this study, did not significantly improve the 3-year outcome. Therefore, a longer course of IFN therapy or combination therapy with ribavirin should be evaluated in patients with HCV-related cirrhosis.

Dacarbazine, fluorouracil, and leucovorin in patients with advanced neuroendocrine tumors: a phase II trial.

Chemotherapy of neuroendocrine tumors must be improved. The most widely used regimen, which combines streptozotocin with fluorouracil, commonly obtains poor results. The best response rate that has been reported for carcinoid tumors is 33%. From July 1991 through September 1994, 18 patients who had advanced neuroendocrine tumors-including nine carcinoid tumors, seven neuroendocrine tumors of unknown primary site, one insulinoma, and one paraganglioma-were treated with a regimen of dacarbazine, 400 mg/m2/day, plus fluorouracil, 1 g/m2/day, with leucovorin, 200 mg/m2/day, for 2 days every 21 days (DTIC-LVFU2 protocol). The results were assessed according to the World Health Organization criteria of toxicity and response. Toxicity was moderate. The most severe side effects were grade 3 vomiting in two patients, grade 3 leukopenia in three patients, and grade 3 mucositis in one patient. The overall response rate was 27%, with only one partial response for carcinoid tumors but one complete and three partial responses for the other tumor types. Efficacy was insufficient in patients who had carcinoid tumors but the combination of dacarbazine with fluorouracil and leucovorin could be an effective regimen for the treatment of neuroendocrine tumors of unknown primary site.

State of hepatitis B virus DNA in hepatocytes of patients with hepatitis B surface antigen-positive and -negative liver diseases.

Using the Southern blot technique and cloned hepatitis B virus (HBV) DNA as a probe, we studied the state of HBV DNA in the liver of 13 patients with hepatocellular carcinoma, 17 patients with chronic hepatitis, and 2 patients with acute hepatitis. The hybridization results were compared with the serological and immunohistological data. Integration of HBV DNA in cellular DNA of the liver from patients with hepatocellular carcinoma was demonstrated. In two patients from which tumorous and nontumorous liver tissue samples were available the integration patterns were different. In one patient with hepatitis B e antigen (HBeAg)-positive early hepatocellular carcinoma, free viral DNA was present in the liver. In some patients with HBeAg-negative chronic hepatitis, without tumor, integration of HBV DNA in cellular DNA was also demonstrated. This suggests that HBV is not the only factor involved in the development of a tumor. In patients with HBeAg-positive chronic hepatitis, free viral DNA was detected in the liver. In the two acute hepatitis patients analyzed, the restriction endonuclease patterns strongly suggested HBV DNA integration. Therefore, viral DNA integration seems to occur early in infection. Whatever the form of the disease, discrete bands were observed, suggesting the existence of limited and specific integration sites in host cellular DNA. The presence of integrated or free DNA sequences has implications for antiviral therapy. In addition, detection of HBV DNA in the liver is another sensitive viral marker that could be useful for diagnostic purposes.
