RESUMEN

This study aimed to determine cancer prevalence occurring after the age of 75 in 45 French nursing homes (NH), as well as residents' characteristics and parameters associated with cancer-specific management. Descriptive retrospective study including 214 residents (mean age, 89.7 years) with cancer diagnosed after age 75. The studied parameters were sociodemographic, functional, nutritional and cognitive data; comorbidity assessment; date of tumoral diagnosis; cancer type; tumoral stage; treatment plan; multidisciplinary staff decision and oncologic follow-up. Our results showed that cancer prevalence in NH was 8.4 ± 1.1%, diagnosed before admission in 63% of cases. The most common tumoral sites were skin (26%), digestive tract and breast (18% for both); 12% had metastasis. Cognitive impairment was the most common comorbidity (42%), and 44% of the residents were highly dependent. Multivariate analysis showed that therapeutic decisions were associated with age. Older patients had less staging exploration (odd ratios [ORs], 0.90, 95% confidence interval [CI], 0.85-0.97) and underwent less cancer-specific treatment (ORs, 0.92; 95%CI, 0.86-0.99). Oncologic follow-up was more frequent in younger patients (ORs, 0.90; 95%CI, 0.81-0.99) and those with recent diagnosis (ORs, 0.37; 95%CI, 0.23-0.61). This study identified factors associated with substandard neoplastic management in elderly NH residents. It highlights needs for information, education and training in cancer detection to improve cancer consideration and care in NH.

RESUMEN

The anti-tumour and anti-metastatic properties of heparins have not been tested in patients with early stage cancer. Whether adjuvant low molecular weight heparin (LMWH) tinzaparin impacts the survival of patients with resected non-small cell lung cancer (NSCLC) was investigated.Patients with completely resected stage I, II or IIIA NSCLC were randomly allocated to receive subcutaneous tinzaparin 100 IU·kg-1 once a day for 12 weeks or no treatment in addition to standard of care. The trial was open-label with blinded central adjudication of study outcomes. The primary outcome was overall survival.In 549 patients randomised to tinzaparin (n=269) or control (n=280), mean±sd age was 61.6±8.9 years, 190 (34.6%) patients had stage II-III disease, and 220 (40.1%) patients received adjuvant chemotherapy. Median follow-up was 5.7 years. There was no significant difference in overall survival between groups (hazard ratio (HR) 1.24, 95% CI 0.92-1.68; p=0.17). There was no difference in the cumulative incidence of recurrence between groups (subdistribution HR 0.94, 95% CI 0.68-1.30; p=0.70).Adjuvant tinzaparin had no detectable impact on overall and recurrence-free survival of patients with completely resected stage I-IIIA NSCLC. These results do not support further clinical evaluation of LMWHs as anti-tumour agents.

RESUMEN

PURPOSE: Medical doctors' (MDs), but not patients', perception of supportive care in cancer (SCC) in France has been previously assessed in a national survey. This study evaluated MDs and patients' perceptions of the SCC organization and implementation in France. METHODS: The French SCC Association conducted two observational studies: study 1 (S1), containing a 30-point questionnaire sent to 2263 MDs, and study 2 (S2), containing a 40-point questionnaire sent to 2000 patients. RESULTS: Overall, 711 MDs completed S1 and 1562 patients completed S2. In S1, 81% of MDs reported relying on a SCC organization and 76% attended SCC multidisciplinary discussions. MDs considered palliative (98%), psychological (98%), and social care (98%) as the top 3 SCC areas of importance for patients. In contrast, patients' priorities were psychology (61%), nutrition (55%) and organization of intake consultations (55%). The concept of SCC was familiar to 34% of patients; according to MDs, this concept was introduced mainly by MDs (78%) and admission nurses (41%). Outpatients identified as professional resources for SCC information general practitioners (84%), nurses (58%), and pharmacists (52%). Patients reported supportive treatment being prescribed in 63% of cases, with 64% receiving information on the negative side-effects. Among MDs, 87% reported proposing palliative and 41% adjuvant SCC treatment. Furthermore, 72% of MDs recommended SCC treatment at the metastatic stage, and 36% immediately following diagnosis. DISCUSSION: Oncologists play a vital role in enhancing SCC efficacy. This can be increased by implementing a multidisciplinary integrated approach or by assuring the availability of patient information.

RESUMEN

AIMS: Vinflunine (VFL) ditartrate, a novel tubulin-targeted inhibitor, is registered for the treatment of patients with advanced or metastatic urothelial transitional cell carcinoma. This phase I study assessed the effect of renal impairment on the pharmacokinetics and tolerability of VFL. METHODS: VFL was infused in patients with advanced/metastatic solid tumours once every 3 weeks with anticipated dose reduction on the first cycle stratified according to the creatinine clearance (CLcr ) values. Pharmacokinetic data were collected on the first two cycles in renally impaired patients (CLcr ≤ 60 ml min(-1) ) and were compared with a control cohort of patients (CLcr > 60 ml min(-1) ). RESULTS: Thirty-three patients (46-86 years) were treated, 13 in group 1 (40 ml min(-1) ≤ CLcr ≤ 60 ml min(-1) ) and 20 in group 2 (20 ml min(-1) ≤ CLcr < 40 ml min(-1) ). The renal dysfunction induced a mean decrease in VFL clearance of 12% in group 1 and 28% in group 2, compared with the control group. The anticipated dose reduction given in renally impaired patients (i.e. 280 mg m(-2) and 250 mg m(-2) in groups 1 and 2, respectively) yielded similar drug exposure to control patients. The tolerance profile of VFL in patients with renal dysfunction was similar to that observed in patients with CLcr > 60 ml min(-1) . CONCLUSION: In conclusion, the recommended doses of intravenous VFL administered once every 3 weeks in cancer patients with renal impairment are 280 mg m(-2) when CLcr is between 40 and 60 ml min(-1) and 250 mg m(-2) when CLcr is between 20 and <40 ml min(-1) .

RESUMEN

OBJECTIVE: We investigated the efficacy and safety of afatinib maintenance therapy in patients with head and neck squamous cell carcinoma (HNSCC) with macroscopically complete resection and adjuvant radiochemotherapy (RCT). METHODS: This French multicentric randomised phase III double-blind placebo-controlled study included adult patients with ECOG-PS≤2, normal haematological, hepatic and renal functions, and non-metastatic, histologically confirmed HNSCC of the oral cavity, oropharynx, larynx or hypopharynx, with macroscopically complete resection and adjuvant RCT (≥2 cycles of cisplatin 100 mg/m2 J1, J22, J43 and 66Gy (2Gy/fraction, 5 fractions/week, conventional or intensity modulated radiotherapy ≥60Gy). Randomised patients were planned to receive either afatinib (afa arm) or placebo (control arm (C)) as maintenance therapy for one year. Primary endpoint was disease free survival (DFS). A 15% improvement in DFS was expected at 2 years with afatinib (from 55 to 70%). RESULTS: Among the 167 patients with resected HNSCC included in 19 cancer centres and hospitals from Dec 2011, 134 patients were randomised to receive one-year maintenance afatinib or placebo (afa:67; C:67). Benefit/risk ratio was below assumptions and independent advisory committee recommended to stop the study in Feb 2017, the sponsor decided premature study discontinuation, with a 2-year follow-up for the last randomised patient. 2y-DFS was 61% (95% CI 0.48-0.72) in the afatinib group and 64% (95% CI 0.51-0.74) in the placebo group (HR 1.12, 95% CI 0.70-1.80). CONCLUSION: Maintenance therapy with afatinib compared with placebo following post-operative RCT in patients with HNSCC did not significantly improve 2y-DFS and should not be recommended in this setting outside clinical trials. CLINICALTRIALS: gov identifier NCT01427478.

RESUMEN

Glioblastoma (GBM) is the most malignant type of primary brain tumor with a very poor prognosis. The actual standard protocol of treatment for GBM patients consists of radiotherapy and concomitant temozolomide (TMZ). However, the therapeutic efficacy of this treatment is limited due to tumor recurrence and TMZ resistance. Recently isolated, glioma stem-like cells (GSCs) are thought to represent the population of tumorigenic cells responsible for GBM resistance and recurrence following surgery and chemotherapy. In addition, MGMT (O6-methylguanine-methyltransferase) methylation is considered as one of the principal mechanisms contributing to TMZ sensitivity of GBM. In this study we have isolated GSCs from 10 adult GBM patients and investigated the relationship between MGMT methylation status and Temozolomide (TMZ) sensitivity of these lines grown either in stem-like or differentiation promoting conditions. Sensitivity to TMZ was significantly associated with MGMT methylation status in cells committed to differentiation but not in stem-like cells. In addition, patients harboring highly methylated MGMT promoters had a longer overall survival. These results reveal the importance of the differentiation process when considering the predictive value of MGMT status in GSCs for clinical response to TMZ.

RESUMEN

Glioblastoma (GBM), the highest-grade form of gliomas, is the most frequent and the most aggressive. Recently, a subpopulation of cells with stem cells characteristics, commonly named "tumor-initiating stem cells" (TISCs) or "cancer stem cells" (CSCs) were identified in GBM. These cells were shown to be highly resistant to chemotherapeutic drugs and to ionizing radiations. Consequently, the knowledge of the signals that regulate the functions and survival of TISCs is crucial. In our work, we describe a neurosphere-initiating cell (NS-IC) assay to quantify TISC/CSCs from patients with GBM and show that these cells are tumorigenic in vivo. We demonstrate that the intracellular signal transducer and activator of transcription STAT3 is constitutively activated by phosphorylation preferentially on serine 727 in these cells. Moreover, we demonstrate that the selective inhibition of STAT3 by the chemical compound Stattic or by siRNA STAT3 abrogates TISC/CSC proliferation and NS-IC suggesting that self-renewal of GBM "stem-like" cells depends on the presence of STAT3 for their maintenance. Finally, we show that inhibition of STAT3 by Stattic sensitizes TISC/CSCs to the inhibitory action of Temozolomide with a strong synergistic effect of both drugs. Overall, these results suggest that strategies focused on STAT3 inhibition are efficient at the level of "stem-like" cells and could be of interest for therapeutic purposes in patients with malignant GBM.

RESUMEN

INTRODUCTION: Management of elderly patients with cancer is challenging worldwide. Improvement of their care pathway should focus on unplanned hospitalizations. This study aimed to compare the geriatric and oncologic profiles of elderly patients with cancer, hospitalized for an acute pathology either in medical oncology or acute geriatric medicine units. METHODS: Epidemiological, analytical, monocentric, transversal study performed in the geriatric and oncological short-stay units of the university hospital of Poitiers (France) from 07/01/2014 to 06/30/2015. Only patients with diagnosed cancer prior to hospitalization were included. The geriatric, oncological and hospitalization data were collected and analyzed. RESULTS: In total, 230 patients were included (156 in geriatrics, 74 in oncology). Alteration of the general condition was the most frequent reason for admission. In multivariate age-adjusted analyses, factors associated with admission to a geriatric unit were co-morbidities (OR=0.18 [95% CI: 0.07-0.46], P<0.01) and dependence (OR=0.07 [95% CI: 0.01-0.36], P<0.01). Ongoing antineoplastic treatment (OR=2.60 [95%CI: 1.14-5.89], P=0.02) and metastatic cancer (OR=2.63 [95%CI: 1.18-5.86], P=0.02) influenced hospitalization in the oncology unit. During the hospital stay there was more frequent psychological support in oncology (OR=45.59 [95%CI: 9.79-212.23], P<0.01) and social support in Geriatrics (OR=0.13 [95% CI: 0.04-0.40], P<0.01). CONCLUSION: This first comparative study showed a significant difference in profiles of elderly patients with cancer hospitalized for an acute problem, depending on the hospital unit. This finding paves the way of improvement of care pathway by formalizing links between these two departments to optimize care and referrals to the most appropriate care unit, according to patients condition, in case of unscheduled hospitalization.

RESUMEN

PURPOSE: Both concurrent chemoradiotherapy (CT-RT) and cetuximab radiotherapy (cetux-RT) have been established as the standard of care for the treatment of locally advanced squamous cell carcinoma of the head and neck. It was not known whether the addition of induction chemotherapy before cetux-RT could improve outcomes compared with standard of care CT-RT. PATIENTS AND METHODS: The current trial was restricted to patients with nonmetastatic N2b, N2c, or N3 squamous cell carcinoma of the head and neck and fit for taxotere, cisplatin, fluorouracil (TPF). Patients were randomly assigned to receive three cycles of TPF followed by cetux-RT versus concurrent carboplatin fluorouracil and RT as recommended in National Comprehensive Cancer Network guidelines. The trial was powered to detect a hazard ratio (HR) of 0.66 in favor of TPF plus cetux-RT for progression-free survival at 2 years. The inclusion of 180 patients per arm was needed to achieve 80% power at a two-sided significance level of .05. RESULTS: Between 2009 and 2013, 370 patients were included. All patients and tumors characteristics were well balanced between arms. There were more cases of grade 3 and 4 neutropenia in the induction arm, and the induction TPF was associated with 6.6% treatment-related deaths. With a median follow-up of 2.8 years, 2-year progression-free survival was not different between both arms (CT-RT, 0.38 v TPF + cetux-RT, 0.36; HR, 0.93 [95% CI, 0.73 to 1.20]; P = .58). HR was 0.98 (95% CI, 0.74 to 1.3; P = .90) for locoregional control and 1.12 (95% CI, 0.86 to 1.46; P = .39) for overall survival. These effects were observed regardless of p16 status. The rate of distant metastases was lower in the TPF arm (HR, 0.54 [95% CI, 0.30 to 0.99]; P = .05). CONCLUSION: Induction TPF followed by cetux-RT did not improve outcomes compared with CT-RT in a population of patients with advanced cervical lymphadenopathy.

RESUMEN

Purpose To investigate the effect of adding concurrent chemotherapy (CT) to cetuximab plus radiotherapy (RT; CT-cetux-RT) compared with cetuximab plus RT (cetux-RT) in locally advanced squamous cell carcinoma of the head and neck (LA-SCCHN). Patients and Methods In this phase III randomized trial, patients with N0-2b, nonoperated, stage III or IV (nonmetastatic) LA-SCCHN were enrolled. Patients received once-daily RT up to 70 Gy with weekly cetuximab or with weekly cetuximab and concurrent carboplatin and fluorouracil (three cycles). To detect a hazard ratio (HR) of 0.64 for progression-free survival (PFS) with 85% power at a two-sided significance level of P = .05, 203 patients needed to be included in each arm. Results Four hundred six patients were randomly assigned to either CT-cetux-RT or cetux-RT. Patient and tumor characteristics were well balanced between arms, including p16 status. With a median follow-up of 4.4 years, the HR for PFS favored the CT-cetux-RT arm (HR, 0.73; 95% CI, 0.57 to 0.94; P = .015), with 3-year PFS rates of 52.3% and 40.5% and median PFS times of 37.9 and 22.4 months in the CT-cetux-RT and cetux-RT arms, respectively. The HR for locoregional control was 0.54 (95% CI, 0.38 to 0.76; P < .001) in favor of CT-cetux-RT. These benefits were observed regardless of p16 status for oropharynx carcinomas. Overall survival (HR, 0.80; P = .11) and distant metastases rates (HR, 1.19; P = .50) were not significantly different between the two arms. The CT-cetux-RT arm, compared with cetux-RT, had a higher incidence of grade 3 or 4 mucositis (73% v 61%, respectively; P = .014) and of hospitalizations for toxicity (42% v 22%, respectively; P < .001). Conclusion The addition of concurrent carboplatin and fluorouracil to cetux-RT improved PFS and locoregional control, with a nonsignificant gain in survival. To our knowledge, this is the first evidence of a clinical benefit for treatment intensification using cetux-RT as a backbone in LA-SCCHN.

RESUMEN

PURPOSE: Onycholysis and skin toxicity occur in approximately 30% of patients treated with docetaxel. We investigated the efficacy and safety of an Elasto-Gel (84400 APT Cedex, Akromed, France) frozen glove (FG) for the prevention of docetaxel-induced onycholysis and skin toxicity. PATIENTS AND METHODS: Patients receiving docetaxel 75 mg/m2 alone or in combination chemotherapy were eligible for this case-control study. Each patient wore an FG for a total of 90 minutes on the right hand. The left hand was not protected and acted as the control. Onycholysis and skin toxicity were assessed at each cycle by National Cancer Institute Common Toxicity Criteria and documented by photography. Wilcoxon matched-pairs rank test was used. RESULTS: Between August 2002 and September 2003, 45 patients were evaluated. Onycholysis and skin toxicity were significantly lower in the FG-protected hand compared with the control hand (P = .0001). Onycholysis was grade (G) 0 in 89% v 49% and G1 to 2 in 11% v 51% for the FG-protected hand and the control hand, respectively. Skin toxicity was G0 in 73% v 41% and G1 to 2 in 27% v 59% for the FG-protected and the control hand, respectively. Median time to nail and skin toxicity occurrence was not significantly different between the FG-protected and the control hand, respectively (106 v 58 days for nail toxicity; 57 v 58 days for skin toxicity). Five patients (11%) experienced discomfort due to cold intolerance. CONCLUSION: FG significantly reduces the nail and skin toxicity associated with docetaxel and provides a new tool in supportive care management to improve a patient's quality of life.

RESUMEN

PURPOSE: This outpatient multicenter trial tested the hypothesis that subcutaneous administration of an interleukin-2 (IL-2)/interferon alfa (IFN alpha) combination produces a response rate greater than 20% in patients with renal cell carcinoma (RCC). PATIENTS AND METHODS: Patients with metastatic RCC received a 12-week induction treatment with subcutaneous IL-2 (5 days/wk, 9 and 18 million U/d)/IFN alpha (3 days/wk, 6 million U/d). After evaluation, patients with objective response or stable disease were randomly assigned to maintenance treatment or short consolidation treatment. RESULTS: Lack of benefit was shown at the 12th sequential analysis, and the trial was closed. At the end of the induction period, 26 (21%) of 122 patients had objective responses (including six complete responses). Thirty-three patients (27%) developed severe toxicity requiring dose reductions, delayed treatment, or treatment termination. Survival rates at one, two, and four years were 63%, 38%, and 17%, respectively. Three-year survival was 20% in patients with two poor prognosis factors and 37% in patients with one or no poor prognosis factors (P =.016). Three-year survival was significantly better (P < 10-3) in patients with erythrocyte sedimentation rate less than 35 mm (43%) compared with those with 1-hour sedimentation rate greater than 35 mm (19%). CONCLUSION: This study confirms the importance of prognostic factors when initiating cytokine immunotherapy in patients with metastatic RCC and underlines the prognostic value of erythrocyte sedimentation rate before treatment initiation. Nonetheless, this subcutaneous IL-2/IFN alpha combination does not improve response rate or survival compared with subcutaneous IL-2 alone, although a definitive conclusion cannot be drawn in the absence of a randomized study comparing the two treatments.

RESUMEN

PURPOSE: This is a phase I, escalating-dose trial targeting exclusively patients with non-small cell lung cancer (NSCLC), investigating pemetrexed and fixed-dose cisplatin concurrently administered with high-dose radiotherapy (RT) after induction chemotherapy (CT). Primary objective was to determine the maximum tolerated dose and recommended phase II dose of pemetrexed. PATIENTS AND MATERIALS: Patients with unresected stage III NSCLC, planned V20 ≤ 35%, and FEV ≥ 1.3 L, were treated every 21 days for 2 cycles (pemetrexed 500 mg/m2; cisplatin 75 mg/m2), followed by 2 cycles of concurrent CT-RT: pemetrexed starting dose was 400 mg/m2, escalated up to 800 mg/m2 per 100mg/m2 dose level (DL), cisplatin at 75 mg/m2 and RT at fixed dose of 66 Gy/33 fractions. RESULTS: Nine of 10 enrolled patients (age range 46-68 years; 6 men; ECOG PS 0 [6 patients], PS 1 [4]; stage IIIA [1], IIIB [9]; 6 adenocarcinomas, 3 squamous cell carcinomas, 1 large cell carcinoma) were entered on 3 DLs. Dose escalation of pemetrexed was conducted up to 600 mg/m2 based on the independent safety monitoring board recommendation. One dose-limiting toxicity occurred at DL3: Grade 4 septic shock. Grade 3 related toxicities: 2 neutropenia at DL3, 2 lymphopenia per DL (3 recurrent), 2 leukopenia (1 recurrent) at DL3, 1 gastric pain (DL3), 1 nausea and 1 recurrent vomiting (DL2). No Grade 3/4 radiation-related toxicities were observed. No toxic death was observed. Disease control rate was 77.7% (1 CR, 4 PR, 2 SD). One-year survival rate was 90%. CONCLUSIONS: This phase I report of pemetrexed is dedicated to NSCLC with induction therapy and fixed high-dose RT. Pemetrexed at 500 mg/m2, concurrently given with cisplatin and RT was well tolerated and appears to be the only third-generation agent that can likely be recommended safely at full dose in future trials with concurrent RT.

RESUMEN

It is now well established that metastatic colorectal cancer patients without KRAS mutation (codon 12) benefit from treatment with an epidermal growth factor receptor monoclonal antibody (anti-EGFR mAb). Recently, EFGR and KRAS mutations have been shown to exist in patients who developed resistance to anti-EGFR mAb. We analyzed KRAS, BRAF V600E and EGFR S492R mutations in 37 post-anti-EGFR mAb tumor samples from 23 patients treated with chemotherapy plus anti-EGFR mAb. No EGFR S492R mutation was detected. A KRAS mutation was found after anti-EGFR mAb in only one tumor. Our results suggest that acquired EGFR S492R and KRAS mutations do not constitute the main mechanism of resistance to anti-EGFR mAb in combination with chemotherapy.

RESUMEN

PURPOSE: To compare the efficacy and safety of induction chemotherapy (ICT) followed by chemoradiotherapy (CRT) or bioradiotherapy (BRT) for larynx preservation (LP). PATIENTS AND METHODS: Previously untreated patients with stage III to IV larynx/hypopharynx squamous cell carcinoma received three cycles of ICT-docetaxel and cisplatin 75 mg/m(2) each on day 1 and fluorouracil 750 mg/m(2) per day on days 1 through 5. Poor responders (< 50% response) underwent salvage surgery. Responders (≥ 50% response) were randomly assigned to conventional radiotherapy (RT; 70 Gy) with concurrent cisplatin 100 mg/m(2) per day on days 1, 22, and 43 of RT (arm A) or concurrent cetuximab 400 mg/m(2) loading dose and 250 mg/m(2) per week during RT (arm B). Primary end point was LP at 3 months. Secondary end points were larynx function preservation (LFP) and overall survival (OS) at 18 months. RESULTS: Of the 153 enrolled patients, 116 were randomly assigned after ICT (60, arm A; 56, arm B). Overall toxicity of both CRT and BRT was substantial following ICT. However, treatment compliance was higher in the BRT arm. In an intent-to-treat analysis, there was no significant difference in LP at 3 months between arms A and B (95% and 93%, respectively), LFP (87% and 82%, respectively), and OS at 18 months (92% and 89%, respectively). There were fewer local treatment failures in arm A than in arm B; salvage surgery was feasible in arm B only. CONCLUSION: There is no evidence that one treatment was superior to the other or could improve the outcome reported with ICT followed by RT alone (French Groupe Oncologie Radiothérapie Tête et Cou [GORTEC] 2000-01 trial [Induction CT by Cisplatin, 5FU With or Without Docetaxel in Patients With T3 and T4 Larynx and Hypopharynx Carcinoma]). The protocol that can best compare with RT alone after ICT is still to be determined.

RESUMEN

OBJECTIVE: Vinflunine (VFL) (Javlor(®)), a novel fluorinated semisynthetic vinca alkaloid has shown significant antitumor activity in advanced non-small cell lung cancer (NSCLC). We propose to define the recommended dose (RD) of VFL in combination with carboplatin in advanced NSCLC patients. METHODS: This phase I and pharmacokinetic study was designed to determine the maximum tolerated dose and to establish the RD of VFL in combination with carboplatin. Twenty-one chemonaive patients with advanced NSCLC were treated with a first-line chemotherapy of VFL and carboplatin both given on day 1 every 3 weeks with 3 dose levels. RESULTS: Five patients experienced a dose limiting toxicity consisting of constipation in 2 patients and febrile neutropenia in 2 patients. One patient experienced grade 3 abdominal pain concurrent with grade 4 neutropenia. The combination of VFL (320 mg/m(2)) and carboplatin AUC6 was defined as the maximum tolerated dose. The RD was established at the dose of VFL (320 mg/m(2)) combined with carboplatin AUC5. At the RD, 12 patients received a median number of 3 cycles of the combination. Neither VFL nor carboplatin seemed to be influencing the pharmacokinetics of the other. Among 19 patients evaluable for tumor response, 7 had a partial response and 7 experienced stable disease. CONCLUSIONS: The combination of VFL (320 mg/m(2)) and carboplatin AUC 5 given once every 3 weeks is established as the RD of the combination, which was shown to be active in these chemonaive NSCLC patients.

RESUMEN

BACKGROUND: The risks of chemoradiotherapy in elderly patients with rectal cancer have not yet been well-characterised. METHODS: We retrospectively reviewed the charts of patients with rectal cancer over 70 years old who were treated with chemoradiotherapy in two French university hospitals. RESULTS: A total of 125 patients were evaluated. Mean age was 75.1 ± 4.1 years and ranged from 70 to 90 years. Adverse effects ≥ grade 2 were observed in 32% of the patients and adverse effects ≥ grade 3 in 15%. Dose reduction for toxicity was performed in 18% of the patients and chemoradiotherapy discontinuation was necessary in 9%. Postoperative morbidity was 16% with two treatment-related deaths. Two-year survival rate was 84%. No variables had any influence on treatment-related adverse events. CONCLUSIONS: In selected elderly patients, chemoradiotherapy is well-tolerated, without any significant increase in adverse events, and the results are similar to those recorded in younger patients.

RESUMEN

INTRODUCTION: Vinflunine (Javlor) has shown significant antitumour activity in advanced non-small cell lung cancer (NSCLC). We propose to define the recommended dose of vinflunine in combination with gemcitabine for treatment of advanced NSCLC in chemonaive patients. METHODS: A phase I and pharmacokinetic study was conducted to determine the maximum tolerated dose and to establish the recommended dose of vinflunine (VFL) administered on day 1 every 21 days combined with gemcitabine given on days 1 and 8 every 3 weeks. RESULTS: Nineteen patients were included in this study. Three patients experienced a dose limiting toxicity, with constipation in one patient, hypertension in one patient, and constipation and febrile neutropenia in one patient. The combination of VFL 320 mg/m² and gemcitabine 1250 mg/m² was defined as the maximum tolerated dose. The recommended dose was established at the dose of VFL 320 mg/m² combined with gemcitabine 1000 mg/m². Neither VFL nor gemcitabine seemed to be influencing the pharmacokinetics of each other. All patients were evaluable for tumor response. Seven presented a partial response and eight experienced a stable disease. CONCLUSIONS: The combination of VFL 320 mg/m² administered on day 1 combined with gemcitabine 1000 mg/m² given on days 1 and 8 every 3 weeks is established as the RD and was shown to be active in these chemonaive NSCLC patients.

RESUMEN

Temozolomide (TMZ) is a second-generation alkylating agent that has recently shown some efficacy in stage IV melanoma. The purpose of this study was to test the efficacy and safety of combination therapy with TMZ and cisplatin (CDDP) in patients with metastatic melanoma. Chemo-naive patients with metastatic cutaneous melanoma were included in a phase II study of combined therapy with TMZ (200 mg/m/day), days 1-5, and CDDP (75 mg/m/day) on day 1. The treatment was given every 28 days, for up to six cycles. The primary endpoint was the overall response rate and the secondary endpoints were progression-free survival, probability of survival, and tolerance. Thirty patients were enrolled into this study. Median age was 59 years. A total of 126 cycles were administered. Grade 3 and 4 hematological toxicity was observed in 14 patients (46.6%) and clinical toxicity in seven patients (23.3%). No complete response was observed among the 30 included patients. Five patients (16.7%) achieved a partial response. An additional six patients (20%) showed disease stabilization and 17 patients (56.6%) revealed progressive disease. Median survival and median response duration were 8 and 7.2 months, respectively. One- and 2-year survivals were 36.7 and 13.3%. One- and 2-year progression-free survivals were 13.3 and 3.3%. Our results suggest that concurrent adjunction of CDDP to TMZ regimen increases toxicity according to this schedule and does not improve the outcome of stage IV melanoma. The objective response rate is close to response rates observed with single-agent chemotherapy.

RESUMEN

PURPOSE: The aim of this study was to assess clinical, laboratory, and subjective (patient's preferences) prognostic factors in hospitalized patients with advanced solid tumors. PATIENTS AND METHODS: This prospective study surveyed 177 patients from two French hospitals who had not reached the stage of active dying but had an estimated survival of less than 6 months (median survival, 58 days). RESULTS: Univariate analysis showed that 10 of the 13 clinical and laboratory factors reported in the literature affected survival at 2 months. Poor prognostic factors were number of metastatic sites, cerebral metastasis, low Karnofsky index, dyspnea at rest, anorexia, edema, confusion, low serum albumin, extremely high leukocyte counts, and high lactate dehydrogenase (LDH) levels. The patient's desire to continue curative treatment was also associated with survival. The multivariate analysis selected four independent criteria: Karnofsky index (in three classes: or= 70%), number of metastatic sites (>or= two or < two), low serum albumin (in three classes: or= 33 g/L), and LDH concentration (>or= 600 IU or < 600 IU). The combination of these four criteria assessed prognosis better than the Karnofsky index alone, producing three prognostic profiles: one with short survival (< 2 months: no patient survived to 4 months); one with an expectation of intermediate survival (25% were alive at 4 months), and a final group surviving for several months (80% were alive at 4 months). CONCLUSION: The prognostic profiles defined by combinations of these four factors may be potentially useful but need further validation before their application in the daily practice.
