Second-line chemotherapy with pegylated liposomal doxorubicin and carboplatin is highly effective in patients with advanced ovarian cancer in late relapse: a GINECO phase II trial.

BACKGROUND: Platinum-based chemotherapy is standard second-line treatment of patients with advanced ovarian cancer (AOC) in late relapse. Pegylated liposomal doxorubicin (PLD) has significant single-agent activity in this setting. Therefore, we evaluated the use of PLD plus carboplatin in this patient population. PATIENTS AND METHODS: PLD 30 mg/m(2) followed by carboplatin at area under the curve (AUC) 5 mg.min/ml, repeated every 28 days for a maximum of nine cycles, was administered to 104 women with AOC relapsing >or=6 months after completion of first- or second-line therapy with platinum-taxane-based regimens. RESULTS: Overall response was 63%, with a 38% complete response, median progression-free survival of 9.4 months, and median overall survival (OS) of 32 months. Grade 3 or 4 neutropenia occurred in 51% of patients, but febrile neutropenia in only 3%. Nonhematologic toxic effects were primarily grades 1 and 2, with low rates of alopecia and neurotoxicity. CONCLUSIONS: PLD plus carboplatin is highly effective, prolongs OS, and is well tolerated in women with AOC in late relapse previously treated with both platinum and taxanes. Evaluation of this regimen in phase III trials is warranted.

A phase II trial of raltitrexed (Tomudex) in advanced pancreatic and biliary carcinoma.

PURPOSE: To evaluate the impact of raltitrexed (Tomudex) on the quality of life in a multicenter, phase II study in advanced pancreatic and biliary carcinomas. PATIENTS AND METHODS: Forty-six patients with advanced, histologically proven pancreatic (n = 37, 80.4%) or biliary (n = 9, 19.6%) carcinoma received 3 mg/m2 raltitrexed intravenously once every 3 weeks. For the quality of life assessments, EORTC QLQ-C30 was used, and the evaluation of the clinical benefit was performed according to the 4 criteria of the clinical benefit response. All patients were assessed for safety, and 41 patients were evaluable for objective response. RESULTS: Patients (63% male/37% female) had a mean age of 61.2 years, 71.7% had a PS of 0-1, 78.3% had metastatic disease, and 63% had at least 2 tumoral sites. A total of 176 cycles were administered with a mean of 4 cycles per patient (range 1-12). Three out of 43 patients evaluable for EORTC QLQ-C30 (7.0%; CI(95%) 1.4-19.0%) had a quality of life improvement. Thirty-two patients fulfilled the 4 criteria required to evaluate the clinical benefit response; 5 were responders (15.6%; CI(95%) 5.3-32.8%); 1 patient was a good responder based on both the EORTC questionnaire and the clinical benefit response. Forty-one patients were assessable for response, 3 responded to treatment (response rate: 6.5 %; CI(95%) 1.3-17.9%). Median survival was 4.6 months (CI(95%) 2.9-8.2 months), the 1-year survival rate was 21.8%. The most common grade 3-4 toxicities were neutropenia (8%), leukopenia (8%), thrombopenia (6%), anemia (6%), liver enzyme elevations (11%), asthenia (9%), vomiting (9%), abdominal pain (7%), and phlebitis (6%). One treatment-related death occurred (neutropenic sepsis). CONCLUSION: Raltitrexed appeared to be generally well tolerated and showed a clinical benefit response and/or quality of life improvement in a limited number of patients.

Patient preference for either the EORTC QLQ-C30 or the FACIT Quality Of Life (QOL) measures: a study performed in patients suffering from carcinoma of an unknown primary site (CUP).

The objective of this study was to examine and compare two core measures of Quality Of Life (QOL) used in cancer clinical trials: the European Organisation for Research and Treatment of Cancer QOL Core Questionnaire 30 (EORTC QLQ-30) and the Functional Assessment of Chronic Illness Therapy (FACIT), in order to identify which one patients have the strongest preference for using. 68 patients suffering from Carcinomas of an Unknown Primary site (CUP) were recruited in a multicentric study; all of them completed both questionnaires, administered in a randomised manner. The criteria were the percentage of preferences, and four indicators of acceptability. The results indicated that an equal proportion of patients preferred the QLQ-C30 (19%) and FACIT (19%). 54% of patients felt both questionnaires were acceptable. All the indicators of acceptability favoured the QLQ-C30. Analysis of open-ended questions shed light on the difficulties encountered by the patients. As no significant preference was observed for one of the questionnaires, the QLQ-C30 was chosen on the basis of its significantly better acceptability criteria.

Docetaxel plus 5-fluorouracil in locally recurrent and/or metastatic squamous cell carcinoma of the head and neck: a phase II multicenter study.

This phase II study evaluated docetaxel-5-fluorouracil (5-FU) in locally recurrent and/or metastatic squamous cell carcinoma of the head and neck (SCCHN). Patients were divided into 2 cohorts--those previously treated with chemotherapy and those nonpretreated--that received docetaxel 75 mg/m2 (day 1) plus 5-FU 1,000 mg/m2/day (days 1-5 every 3 weeks). Of 63 patients entered, 20 (31.7%) were pretreated and 43 (68.3%) were nonpretreated. Fifty-nine patients (93.7%) had received prior radiotherapy. After inclusion of 20 patients, the 5-FU dose was reduced to 750 mg/m2/day due to unacceptable toxicity. The overall response rate (ORR) was 20.6% on radiologic review (22.2%, investigator assessment). Pretreated patients achieved an ORR of 25.0% versus 18.6% for nonpretreated patients. This unexpected finding was partly attributed to differences in patient characteristics between the groups. Overall major grade 3 to 4 toxicities comprised neutropenia (66.6%), febrile neutropenia (31.7%), and mucositis (31.7%). Grade 3 to 4 toxicities were lower at the reduced 5-FU dose (750 mg/m2/day): Febrile neutropenia declined from 40.0% to 27.9%; mucositis declined from 55.0% to 20.9%. Three treatment-related deaths occurred (2 with 5-FU 750 mg/m2/day, 1 with 5-FU 1,000 mg/m2/day). Docetaxel-5-FU appears active in locally recurrent and/or metastatic SCCHN with acceptable toxicity at the dose of 5-FU 750 mg/m2.

Phase II multicentre study of docetaxel plus 5-fluorouracil in patients with anthracycline-pretreated metastatic breast cancer.

The purpose of the study was to determine the efficacy and safety of docetaxel plus continuous infusion of 5-fluorouracil (5-FU) in patients with metastatic breast cancer previously treated with anthracyclines. A total of 41 patients with histologically proven metastatic breast cancer and performance status 0-2, who had received at least one anthracycline-containing regimen, received docetaxel 85 mg m(-2) followed by continuous infusion of 5-FU 750 mg m(-2) day(-1) for 5 days every 3 weeks for up to eight cycles. All patients received corticosteroid premedication, but there was no prophylactic colony-stimulating factor support. The most frequent metastatic sites were the liver (61%), bone (29%), and lung (29%). All 41 patients were assessable for toxicity and 30 were eligible and assessable for efficacy. The objective response rate was 70.0% (95% CI: 53.6-86.4%) for the per protocol group and 53.7% (95% CI: 38.4-68.9%) for the intent-to-treat (ITT) population. For the ITT population, median duration of response was 8.4 months (95% CI: 6.7-12.2 months), median time to progression was 6.7 months (95% CI 5.5-8.6 months), and median survival was 17 months (95% CI: 12.3-not recorded months). Grade 3/4 neutropenia occurred in 54% of patients, with febrile neutropenia in 24% of patients and 5% of cycles, but infections were rare. Stomatitis was frequent, grade 3 in 24% of patients and grade 4 in one patient (2%), but manageable. Diarrhoea was rare, grade 3 in 7% of patients and 1% of cycles. Other grade 3/4 nonhaematological toxicities were infrequent. In conclusion, this docetaxel/5-FU regimen is highly active and well tolerated in patients with anthracycline-pretreated metastatic breast cancer. The efficacy is particularly promising, as one-third of patients were either second-line and/or anthracycline-resistant/refractory.

[Pituitary germinoma presenting as a pseudotumoral lymphocytic hypophysitis in a man].

A 45-year-old man presented with headaches and extraocular muscle palsy due to a sellar mass extending into the right cavernous sinus. Hormonal determinations revealed a gonadotrophic insufficiency. A transsphenoidal surgical removal revealed a lymphocytic hypophysitis with fibrosis and necrosis. Rapid growth of the pseudotumor was noted despite a high dose steroid therapy (1 mg/kg/d) for a month. Further biological and histopathological investigations were performed. They showed a high cerebrospinal fluid (CSF) B-human chorionic gonadotropin (ss-HCG) level of 12 UI/L (normal<5 UI/L), normal plasma BHCG level, and undetectable CSF and plasma alpha-fetoprotein levels. The tumors cells showed a positive reactivity for placental alkaline phosphatase and for vimentin. These findings were consistent with an inflammatory lymphocytic process caused by an intrasellar germinoma. Chemotherapy was ill-tolerated and external radiotherapy was ineffective.

Efficacy and safety of docetaxel (Taxotere) in heavily pretreated advanced breast cancer patients: the French compassionate use programme experience.

The aim of this investigation was to assess retrospectively docetaxel safety and efficacy in advanced breast cancer patients in a French compassionate use programme. Patients had received > 1 prior chemotherapy regimen for advanced disease, were either anthracycline-resistant (that is progressed within 6 months after anthracycline-based chemotherapy) or had received the maximum cumulative dose. The recommended docetaxel dose was 100 mg/m2/cycle (75 mg/m2 in case of liver function impairment: transaminases > 1.5 x upper limit of normal (ULN), alkaline phosphatases > 3 x ULN). Between August 1993 and December 1995, 889 patients were treated in 67 French centres, of whom 870 were evaluable for safety and 825 were evaluable for patient and treatment characteristics and efficacy. 20.5% (of the 825 patients evaluable for baseline characteristics) had poor performance status (PS > or = 2), 49.3% liver metastasis and 9.6% biological liver dysfunction. 98.4% had been previously treated by anthracyclines, 50.8% had resistant disease and 37.1% had received > 2 prior palliative chemotherapy lines. The most frequent severe toxicity, febrile neutropenia (reported in 223/870 (25.6%) patients evaluable for safety), caused 10 deaths, 6 of these being patients with severe liver impairment before inclusion. Fluid retention syndrome and other common non-haematological toxicities were well tolerated. 3.1% (28/889) of all patients and 11.4% of those with liver dysfunction, died from treatment-related causes. The overall response rate in 825 assessable patients was 22.9% (95% confidence interval (CI): 20.2-26.2%). Median time to treatment failure was 4 months (95% CI: 3.6-4.3) and median survival was 9.8 months (95% CI: 8.8-10.7). This report on the largest series of unselected advanced breast cancer patients treated with docetaxel, supports previous phase II studies, confirming docetaxel's utility in patients relapsing after failing anthracycline-containing palliative chemotherapy.

Dose-finding study of docetaxel and doxorubicin in first-line treatment of patients with metastatic breast cancer.

PURPOSE: To determine the maximum tolerated dose (MTD), the dose-limiting toxicity (DLT) and the recommended dose of docetaxel in combination with doxorubicin, and to evaluate the activity in patients with advanced breast cancer. PATIENTS AND METHODS: Forty-two women with untreated metastatic breast cancer (79% with visceral metastases; 52% with prior adjuvant anthracycline therapy) were treated with doxorubicin (40-60 mg/m2) i.v. bolus followed one hour later by docetaxel (50-85 mg/m2) one-hour i.v. infusion every three weeks, without G-CSF support. RESULTS: The MTD occurred at the dose level combining 85 mg/m2 of docetaxel and 50 mg/m2 of doxorubicin, with the DLT being neutropenic sepsis. Neutropenia and/or its complications were manageable and no grade 3-4 or severe non-hematological toxicities were observed. Fluid retention was frequent but never severe. With a median cumulative dose of doxorubicin of 392 mg/m2 (240-559 mg/m2) and a median follow-up time of 29 months (9(+)-41), no congestive heart failure was observed. High activity was observed at all dose levels, particularly the last four, with a response rate of 81% (95% confidence interval (95% CI): 62.5-92.5). Median time to progression was 46 weeks (6(+)-62). Two-year survival was 66%, and median survival has not yet been reached. CONCLUSIONS: Docetaxel-doxorubicin is feasible, safe and highly active. The incidence of febrile neutropenia without G-CSF requires careful monitoring but is acceptable in this setting. There does not appear to be an increase in the cardiac toxicity of doxorubicin. The recommended doses is either docetaxel 75 mg/m2 and doxorubicin 50 mg/m2 or docetaxel 60 mg/m2 and doxorubicin 60 mg/m2, administered every three weeks.

Case-control study of the risk factors for age related macular degeneration. France-DMLA Study Group.

AIM: A case-control study was initiated to determine the risk factors for the development of age related macular degeneration (AMD). METHODS: Study participants, who were all white, aged 50-85 years, and were recruited from private ophthalmology practices. Each practitioner enrolled patients with bilateral AMD, who were then matched with controls for sex and age. Environmental factors and systemic and ocular histories were screened. All patients had bilateral red-free fundus photographs and fluorescein angiography. Photographs were classified into pigment epithelium alterations, drusen, geographic atrophy, and exudative AMD. Statistical analysis included the identification of risk factors for AMD. A multivariate analysis was performed at the end of the study. Analysis included the entire study population and was carried out for each stage of AMD. RESULTS: 1844 controls were compared with 1844 patients with AMD. Mean age was 71 years for controls and 72 for cases. Logistic regression identified six major risk factors for AMD (whole population): arterial hypertension (odds ratio (OR) = 1.28), coronary disease (OR = 1.31), hyperopia (OR = 1.33), light coloured irises (OR = 1.22), and lens opacities or previous cataract surgery (OR = 1.55). The significance of vascular risk factors was increased for late stages of AMD, especially the atrophic forms (coronary disease, OR = 3.19). CONCLUSIONS: This large case-control study confirms some of the risk factors previously identified and may contribute to the determination of methods for prevention of AMD.

Mitomycin-vinorelbine as second line chemotherapy in metastatic breast cancer

Fourty-six patients (41 evaluable) were treated in second line chemotherapy of metastatic breast cancer (MBC) by an association of mitomycin (M), vinorelbine (V) (M 8 mg/m2 D1, V 25 mg/m2 D1 and DI 8 every 4 weeks). Median age was 58 years (36-78), median performance status 1 (0-3). Thirty-seven per cent of the tumors were estrogen receptors positive and 17% progesterone receptors positive.eventeen patients received an adjuvant chemotherapy and 39 a first line chemotherapy with anthracyclin (A). The median number of metastatic sites was 2 (1-4) and 27 patients (67%) had visceral metastases. Twelve patients were refractory to anthracyclins and 5 resistant. No toxic death nor hemolytic uremic syndrom were observed.even (3,7%) febrile neutropenias happened responsible for 4 hospitalizations. A grade 3 or 4 neutropenia was noted in 34% of the cycles but no other clinic toxicity nor grade 3 or 4 thrombopenia. The rate of objective response (OR) was 37,5% with 2 complete responses (CR) and 13 partial responses (PR).even patients had stable disease and 18 progressed. The rate of hepatic OR was 31%. Five (40%) A-refractory patients responded but no resistant patient. Median OR time was 10 weeks (8-12) and median OR duration was 5 months (3-6). Median survival was 11,5 months. MV association is well tolerated and effective in second line chemotherapy for MBC even with hepatic metastasis and in patients refractory to anthracyclins.

Taxoids in combination chemotherapy for metastatic breast cancer.

The rationale for the development of new drug combinations is to combine optimal doses of drugs with single agent activity which are not cross-resistant and have non-overlapping toxicities. Anthracyclines are widely accepted as the agents of choice for first-line treatment of metastatic breast cancer and have been tested in combination with the taxoids, docetaxel (Taxotere) and paclitaxel (Taxol). Toxicity problems have emerged using anthracyclines and paclitaxel, with sequence- and schedule-dependent toxic effects including dose-limiting typhlitis and mucositis, as well as febrile neutropenia and, in one study, cardiomyopathy. The dose-limiting toxicities of the combination of docetaxel and doxorubicin are neutropenia and infection, and preliminary results indicate a response rate of 89%. There is a need to develop a combination treatment regimen which is non-cross-resistant with anthracyclines. Vinorelbine (Navelbine) has single agent activity against metastatic breast cancer and has been used in combination with taxoids. The dose-limiting toxicities of the vinorelbine-paclitaxel combination are febrile neutropenia, pelvic pain, fatigue and paraesthesias. The dose-limiting toxicities of the combination of docetaxel and vinorelbine are febrile neutropenia and mucositis. The overall response rate for this combination was 67% and studies are ongoing.

Antioxidant activity of plasma from subjects with and without senile cataract.

The relationship between overall plasma antioxidant activity and senile cataract was examined in 148 subjects aged 37-90 years. Antioxidant activity of plasma from 52 control and 96 patients with senile cataract was determined by a method which measures the capacity of plasma to inhibit auto-oxidation of bovine brain homogenate. In contrast to previous studies which demonstrated a relationship between decreased levels of antioxidant components in blood and the occurrence of lens opacities, the present study does not show any significant difference between subjects with and without senile cataract.

[Ocular complications of intracarotid chemotherapies with nitrosourea agents].

The authors report ocular complications in intracarotid chemotherapy with Nitrosyl-urea on 39 patients with intracerebral malignant tumor (anaplastic astrocytoma). Internal carotid infusion catheter was in infra-ophthalmic position. They also report 13 ocular complications (33% of cases) as arterial retinal occlusions essentially, ipsilateral to catheter site. Their study and literature revue emphasize five ocular toxicity factors; intracarotid catheter position, type of drug, its quantity, its solubility and solvent, the rate of infusion.
