RESUMO

PURPOSE: Malnutrition is a predictor of poor outcomes in patients with cancer. Little is known about the benefit of nutritional support in these patients. The purpose of this study was to assess the impact of home parenteral nutrition (HPN) on quality of life (Qol) in cancer patients. METHODS: We performed an observational prospective study to determine the impact of HPN on Qol in a population of patients with heterogeneous cancer. Physicians, patients and family members had to complete a questionnaire before HPN administration and 28 days after the course of HPN. Qol was evaluated using the self-administered questionnaire FACT-G. RESULTS: We included 767 patients with cancer of whom 437 ended the study. Mean patient age was 63±11.4 years and 60.5% were men. Primary gastrointestinal cancer was reported in 50% of patients and 65.3% were presenting metastases. Malnutrition was reported in 98.3%. After 28 days of HPN intake, significant improvement was observed in the Qol (49.95±5.82 vs. 48.35±5.01 at baseline, p<0.0001). The mean weight, serum albumin and the nutrition risk index had also improved significantly. Most patients (78%) had perceived a positive impact of the HPN. A significant improvement in patient's well-being was perceived also by family members and physicians. CONCLUSIONS: Our data suggest that preventing and correcting malnutrition using HPN in patients with cancer might have a significant benefit on their well-being. Randomized controlled studies are required to confirm this finding.

RESUMO

BACKGROUND: The purpose of this epidemiologic survey was to describe the management of second-line therapy for patients with stage IIIB-IV non-small cell lung carcinoma (NSCLC) following docetaxel-cisplatin as first-line therapy. METHODS: Between June 2003 and December 2004, 265 patients were enrolled. The data registered were the choice of cytotoxics, the safety profile, the efficacy and the clinical benefit. RESULTS: Two hundred and sixty one patients were treated with docetaxel-cisplatin as a first-line regimen and 181 received a second line. This second line was a single agent regimen in 58% of cases and a gemcitabine based treatment in 60.8%. The main criterion for the choice of second-line therapy was the safety profile in 34.3% of cases. The overall response rate was 16.6% after the second line and clinical benefit was reported in 43.6% of patients. CONCLUSION: In more than 2/3 of patients with NSCLC the docetaxel-cisplatin combination leaves the opportunity to give a second-line treatment, providing satisfying results in terms of clinical benefit. In this study gemcitabine was the most widely prescribed second-line treatment, mainly as a single agent.

RESUMO

PURPOSE: The pharmacokinetics (PK) of platinum was investigated and compared in patients with normal (NRF) and impaired renal function (IRF), after they had received oxaliplatin at the recommended dose and delivery modality. METHODS: Oxaliplatin was administered at 130 mg/m(2) as a 2-h infusion without hydration. Patients were recruited and classified according to their creatinine clearance (CrCl > or < 60 ml/min), calculated using the Cockcroft and Gault formula. Blood was taken for PK analysis during and after the infusion. Twenty-three patients were included in the PK analysis (13 NRF and 10 IRF). At inclusion, the median CrCls were 70.5 ml/min (range 63-136) for the NRF group and 42 ml/min (range 27-57) for the IRF group. Three patients underwent a second course of treatment and additional blood sampling for analysis. Platinum levels in the plasma, ultrafiltrate and red blood cells (RBCs) were measured using flameless atomic absorption spectrophotometry (FAAS). RESULTS: Following the administration of oxaliplatin, platinum binding to plasma proteins and RBCs was rapid and extensive; at the end of the 2-h infusion, 27% of the platinum in the plasma remained free (40% bound to RBCs, 33% bound to plasma proteins). Neither the mean maximal concentration (C(max)) of total platinum in the plasma, the mean C(max) of ultrafilterable platinum in the plasma, nor the maximal platinum content in the RBCs differed significantly between the two groups (2.59 vs 2.58 microg/ml, 1.09 vs 1.28 microg/ml and 2. 06 vs 2.17 microg/ml, respectively, for patients with NRF vs IRF). After the end of the infusion, levels of total and free (ultrafilterable) platinum in the plasma declined biexponentially. The plasma clearance of both total and free platinum as well as the area under the curve (AUC) of the free platinum fraction correlate with the calculated CrCl (P=9 x 10(-3), P=3.1 x 10(-5) and P=9 x 10(-6), respectively). After a single course of oxaliplatin, toxicities reported in the two groups of patients were similar. CONCLUSIONS: Our results are in agreement with the in vitro data concerning the extensive binding of oxaliplatin to plasma proteins and RBCs. They also reveal a strong negative correlation between free drug plasma availability and renal function, with a corresponding positive correlation between clearance of the plasmatic platinum and renal function. Thus, renal impairment entails a greater overall exposure to platinum in the plasma. However, this study failed to elicit any relationship between moderate renal impairment and the acute toxicity associated with oxaliplatin.

RESUMO

BACKGROUND: Many patients with advanced NHL ultimately relapse and require salvage treatment. Oxaliplatin, a diaminocyclohexane (DACH) platinum, has shown a differential spectrum of cytotoxicity with cisplatin, with activity in primary or secondary cisplatin-resistant solid tumors (colon and ovarian cancer). We report the tolerance/activity of this platinum derivate in previously-treated NHL patients. PATIENTS AND METHODS: From July 1988 to February 1994, 22 patients (11 men, 11 women) with recurrent NHL received single-agent oxaliplatin (100-130 mg/m2 i.v. over two hours with antiemetic premedication, q three weeks). All had been previously treated (median number of prior chemotherapy regimens 2, range 1-7) > or = 1 alkylating agent: 22 patients, anthracyclines: 18 patients, cisplatin: four patients, and radiation: 11 patients. Fourteen patients (63%) had progressive disease as best response to their last chemotherapy, and were considered treatment-refractory. All histologies were centrally reviewed in accord with the R.E.A.L. Classification; they were: eight follicular, five MCL, three diffuse large cell, two MALT, one lymphoplasmocytoid, and three other. RESULTS: A total of 144 cycles were administered for a median number of 6 (range 1-30) per patient. The objective response rate was 40% (95%, CI: 21-64), including one CR (MCL) and eight PRs (four follicular, two MCL, two MALT). The median response duration was 27 months (range 5-44). Treatment-related toxicity was limited to grade 1-2 nausea/vomiting and reversible grade 1-2 peripheral neuropathy in most of the patients. CONCLUSION: Oxaliplatin is an active agent in relapsed/refractory NHL, including the MCL type. Its safety profile makes this agent a good candidate for the development of combined salvage regimens. Further phase II studies are needed to confirm these preliminary results.

RESUMO

BACKGROUND: The combination of 5-fluorouracil (5-FU), leucovorin (LV), and oxaliplatin (I-OHP) was shown to be both more active against metastatic colorectal carcinoma and better tolerated if the drug delivery rate was chronomodulated according to circadian rhythms rather than constant. This allowed the authors to intensify the three-drug chronotherapy regimen and to assess its activity as the initial treatment of metastatic colorectal carcinoma patients in ten centers from four countries. METHODS: Patients with previously untreated and inoperable measurable metastases from colorectal carcinoma received a daily administration of chronomodulated 5-FU (700 mg/m2/day, peak delivery rate at 04:00 hours), LV (300 mg/m2/day, peak delivery rate at 04:00 hours), and 1-OHP (25 mg/m2/day, peak delivery rate at 16:00 hours) for 4 days every 14 days. Intrapatient escalation of 5-FU dose was performed if toxicity was less than World Health Organization (WHO) Grade 2. RESULTS: Of 90 enrolled patients, 35 had a WHO performance status of 1 or 2; 49 had metastases in > or = 2 organs. The liver was involved in 79 patients, 30 of whom had clinical hepatomegaly. The main dose-limiting toxicities were WHO modified Grade 3 or 4 diarrhea (41% of patients, 8.2% of courses), stomatitis (30% of patients, 5.1% of courses), and Grade 2 cumulative peripheral sensory neuropathy (19% of patients after 12 courses). Two patients died with severe gastrointestinal toxicity. Using the intent-to-treat method, the overall objective response rate was 66% (95% confidence limits, 56-76%). Surgical removal of previously inoperable metastases was successful in 31 patients (34%). Histologic necrosis of metastases was >90% in 7 patients and complete in 1 patient. The median progression free survival and survival durations were 8.4 months (range, 5.9-10.9 months) and 18.5 months (range, 13.2-23.8 months), respectively, with 38% of the patients alive at 2 years of follow-up. CONCLUSIONS: The objective response rate appeared to be approximately 3-fold as high as that achieved with current 5-FU-based regimens and translated into an approximately 50% increase in median survival. The hypothesis that this intensified, ambulatory, chronotherapy regimen can increase survival currently is being investigated in a multicenter randomized study conducted by the European Organization for Research and Treatment of Cancer Chronotherapy Study Group.
