A randomised clinical trial of two docetaxel regimens (weekly vs 3 week) in the second-line treatment of non-small-cell lung cancer. The DISTAL 01 study

Docetaxel (75 mg m(-2) 3-weekly) is standard second-line treatment in advanced non-small-cell lung cancer (NSCLC) with significant toxicity. To verify whether a weekly schedule (33.3 mg m(-2) for 6 weeks) improved quality of life (QoL), a phase III study was performed with 220 advanced NSCLC patients, < or =75 years, ECOG PS < or =2. QoL was assessed by EORTC questionnaires and the Daily Diary Card (DDC). No difference was found in global QoL scores at 3 weeks. Pain, cough and hair loss significantly favoured the weekly schedule, while diarrhoea was worse. DDC analysis showed that loss of appetite and overall condition were significantly worse in the 3-week arm in the first week, while nausea and loss of appetite were more severe in the weekly arm in the third week. Response rate and survival were similar, hazard ratio of death in the weekly arm being 1.04 (95% CI 0.77-1.39). A 3-weekly docetaxel was more toxic for leukopenia, neutropenia, febrile neutropenia and hair loss; any grade 3-4 haematologic toxicity was significantly more frequent in the standard arm (25 vs 6%). The weekly schedule could be preferred for patients candidate to receive docetaxel as second-line treatment for advanced NSCLC, because of some QoL advantages, lower toxicity and no evidence of strikingly different effect on survival.

Retrospective analysis of adverse drug reactions induced by gemcitabine treatment in patients with non-small cell lung cancer

Non-small cell lung cancer (NSCLC) is the leading cause of cancer death in the world. Traditional chemotherapy for advanced NSCLC is often considered excessively toxic. Recent clinical trials documented that gemcitabine may represent a good therapeutical option in patients with NSCLC. Aim of our research was to retrospectively evaluate the adverse effects induced by gemcitabine in patients with NSCLC from 1 January 1997 to 31 December 2002, in clinical records of Oncology Divisions of "S. Giovanni di Dio" Hospital of Crotone, "Ospedali Riuniti" Hospital of Reggio Calabria, Hospital of Paola, and in Pneumological Oncology Division of "Mariano Santo" Hospital of Cosenza, Italy. Clinical records of patients treated with gemcitabine (1000mgm(-2) on days 1 and 8) were reviewed and following data were obtained: sex and age of the patients, histologic diagnosis and disease stage, World Health Organisation (WHO) performance status and toxic effects induced by gemcitabine. We reported that 71.6% of NSCLC patients (age range 48-77 years; 135 males, 27 females; performance status 0=53, 1=109) were eligible for our study. Side effect of gemcitabine involved gastrointestinal system (nausea, vomiting and diarrhoea) and only in the last cycles (VIII-XI) emopoiethic system (leukopenia, neutropenia, thrombocytopenia and anemia). Grade IV vomiting occurred in three patients, thrombocytopenia in two. Grade III leukopenia was observed in three patients. Other toxicities were mild. None of the patients died during chemotherapy. In conclusion, these data showed that gemcitabine present a very good tolerability in patients with NSCLC. Therefore, it could be considered as a new therapeutic agents to use as first line therapy for this disease.

Prevalence and management of pain in Italian patients with advanced non-small-cell lung cancer

Pain is a highly distressing symptom for patients with advanced cancer. WHO analgesic ladder is widely accepted as a guideline for its treatment. Our aim was to describe pain prevalence among patients diagnosed with advanced non-small-cell lung cancer (NSCLC), impact of pain on quality of life (QoL) and adequacy of pain management. Data of 1021 Italian patients enrolled in three randomised trials of chemotherapy for NSCLC were pooled. QoL was assessed by EORTC QLQ-C30 and LC-13. Analgesic consumption during the 3 weeks following QoL assessment was recorded. Adequacy of pain management was evaluated by the Pain Management Index (PMI). Some pain was reported by 74% of patients (42% mild, 24% moderate and 7% severe); 50% stated pain was affecting daily activities (30% a little, 16% quite a bit, 3% very much). Bone metastases strongly affected presence of pain. Mean global QoL linearly decreased from 64.9 to 36.4 from patients without pain to those with severe pain (P<0.001). According to PMI, 616 out of 752 patients reporting pain (82%) received inadequate analgesic treatment. Bone metastases were associated with improved adequacy and worst pain with reduced adequacy at multivariate analysis. In conclusion, pain is common in patients with advanced NSCLC, significantly affects QoL, and is frequently undertreated. We recommend that: (i) pain self-assessment should be part of oncological clinical practice; (ii) pain control should be a primary goal in clinical practice and in clinical trials; (iii) physicians should receive more training in pain management; (iv) analgesic treatment deserves greater attention in protocols of anticancer treatment.

Determination of disodium clodronate in human plasma and urine using gas-chromatography–nitrogen-phosphorous detections: validation and application in pharmacokinetic study

We present a specific method for the determination of disodium clodronate in human plasma and urine using a gas-chromatographic system with nitrogen phosphorus detector (NPD). The compound was extracted from plasma and urine samples by an anion-exchange resin and derivatizated with bistrimethylsilyltrifluoroacetamide (BSTFA). Sodium bromobisphosphonate was used as internal standard. The calibration curves were linear in both plasma and urine, with a regression coefficient r > 0.9975 in plasma and r > 0.9977 in urine. The limit of quantitation was 0.3 microg/ml in plasma and 0.5 microg/ml in urine. The method was validated by intra-day assays at three concentration levels. During the study we carried out inter-day assays to confirm the feasibility of the method. The precision in plasma at 0.5, 15, and 45 microg/ml was 12.4, 0.2, and 6.5% (n = 40), respectively; in urine at 0.8, 8, and 40 microg/ml it was 8.6, 6.4, and 9.3% (n = 40), respectively. The method was accurate and reproducible, and was successfully applied to determine the pharmacokinetic parameters of clodronate in healthy volunteers after intravenous infusion and intramuscular injection of 200 mg of the compound. The Cmax after intravenous infusion and intramuscular injection was 16.1 and 12.8 microg/ml, respectively. AUC(0-48 h) after infusion administration and intramuscular injection was 44.2 +/- 18.0 and 47.5 +/- 12.4 h microg/ml, respectively. The elimination half-life in both administrations was 6.31 +/- 2.7 h.

Supportive care in patients with advanced non-small-cell lung cancer

The present study describes supportive care (SC) in patients with advanced non-small-cell lung cancer (NSCLC), evaluating whether it is affected by concomitant chemotherapy, patient's performance status (PS) and age. Data of patients enrolled in three randomised trials of first-line chemotherapy, conducted between 1996 and 2001, were pooled. The analysis was limited to the first three cycles of treatment. Supportive care data were available for 1185 out of 1312 (90%) enrolled patients. Gastrointestinal drugs (45.7%), corticosteroids (33.4%) and analgesics (23.8%) were the most frequently observed categories. The mean number of drugs per patient was 2.43; 538 patients (45.4%) assumed three or more supportive drugs. Vinorelbine does not produce substantial variations in the SC pattern, while cisplatin-based treatment requires an overall higher number of supportive drugs, with higher use of antiemetics (41 vs 27%) and antianaemics (10 vs 4%). Patients with worse PS are more exposed to corticosteroids (42 vs 30%). Elderly patients require drugs against concomitant diseases significantly more than adults (20 vs 7%) and are less frequently exposed to antiemetics (12 vs 27%). In conclusion, polypharmacotherapy is a relevant issue in patients with advanced NSCLC. Chemotherapy does not remarkably affect the pattern of SC, except for some drugs against side effects. Elderly patients assume more drugs for concomitant diseases and receive less antiemetics than adults.

[Evaluation of malnutrition risk in adult hospital patients]

BACKGROUND

The aim of the study was to evaluate the validity and reliability of a risk of malnutrition screening tool (MST) proposed by Ferguson et al. for adult hospital patients.

METHODS

The study included 207 consecutive patients admitted to a Hospital (118 males, 89 females, aged 61+/-16 years) including internal medicine (89), lung (60) and surgical (58) patients. The MST, consisting of three questions regarding appetite and recent unintentional weight loss, was applied to each patients. Peripheral lymphocytes and serum albumin considered as predictor of nutritional status were also evaluated.

RESULTS

Forty-two patients (20% of overall population) resulted malnourished at admission and nutrition support was rapidly established. Of the remaining, 141 (85%), according to the score of MST were not at risk of malnutrition, while 24 (15%) were classified at risk. Peripheral lymphocytes and serum albumin were unable to discriminate the risk in well-nourished patients.

CONCLUSIONS

The proposed MST is confirmed as strongly predictor of nutritional status. It is a simple, quick, reliable, valid tool and can be carried out nursing staff. Its routine application will consistently identify patients at risk of malnutrition so that nutrition care can be promptly started.

[Use of monofilament prosthesis in inguinal hernia treatment: cost-benefit ratio]

BACKGROUND

The authors aimed to demonstrate the real advantages in terms of cost and patient comfort of inguinal hernia surgery using monofilament prostheses.

METHODS

A retrospective survey was carried out on two groups of patients: the first group, consisting of 1032 patients who underwent inguinal hernia surgery under general anesthetic between 1985 and 1995 at the Institute of General Surgery at the University Polyclinic of Messina, included cases of both emergency and elective surgery that did not use monofilament prosthesis. The second group, consisting of 348 patients operated under local anesthesia between 1996 and 1999 at the IV Division of General Surgery at the University Polyclinic of Messina, included cases of both emergency and elective surgery using tension-free techniques and polypropylene mesh. The numbers of recidivations and complications were compared, together with the relative costs of the methods used in both groups.

CONCLUSIONS

In the light of these experimental results, it is clear that the use of biocompatible alloplastic materials in monofilament considerably reduces the risks of recidivation, without no significant increase in the number of dehiscences, infections or postoperative complications. Moreover, there was a striking reduction in costs linked not only to the shorter hospitalisation of patients and the reduced use of painkillers, but also a fall in the number of future hospital admissions owing to recidivation.

[Carcinoma of the gastric stump]

After having emphasized that carcinoma of the gastric stump represents a "major" risk in patients undergoing gastric resection, the authors describe the physiopathology of the new anatomical and functional status of the gastroenteric apparatus and underline the probable etiopathogenetic stages attributable to carcinogenesis. They then describe the treatment of this neoplasia with a marked aggressive character and conclude with the affirmation that the surgeon's efforts must be focused on the correct execution of gastroresection and the follow-up of gastro-resected patients in order to allow the early identification of precancerous conditions and therefore the commencement rational oncological prophylaxis.

Cisplatin-vindesine-mitomycin (MVP) vs cisplatin-ifosfamide-vinorelbine (PIN) vs carboplatin-vinorelbine (CaN) in patients with advanced non-small-cell lung cancer (NSCLC): a FONICAP randomized phase II study. Italian Lung Cancer Task Force (FONICAP)

In the present multicentre randomized phase II trial, the activity and toxicity of three platinum-based combination regimens for the treatment of advanced non-small-cell lung cancer (NSCLC) were evaluated. The three regimens were: MVP (mitomycin-C 6 mg m(-2) on day 1, vindesine 3 mg m(-2) on days 1 and 15, and cisplatin 80 mg m(-2) on day 1 every 28 days), PIN (cisplatin 80 mg m(-2) day 1, ifosfamide 3 g m(-2) day 1 and vinorelbine 25 mg m(-2) day 1 and 8 every 21 days) and CaN (carboplatin 350 mg m(-2) day 1 and vinorelbine 25 mg m(-2) days 1 and 8 every 28 days). A total of 140 chemotherapy-naive patients entered the study; 49 patients were treated with MVP, 48 with PIN and 43 with CaN. Sixty-seven per cent of the patients had stage IV disease. Response rates, calculated on an 'intention to treat' basis, were as follows: MVP, 14.3% (95% CI 5.94-27.2%); PIN, 16.7% (95% CI 7.4-30.2%); and CaN, 14% (95% CI 5.3-27.9%). The overall median survivals were 256, 269 and 243 days for patients treated with MVP, PIN and CaN respectively. Myelosuppression was the most frequent toxicity: grade 3-4 leucopenia was observed in 14.3%, 25% and 18.6% of patients treated with MVP, PIN and CaN respectively. This multicentre phase II randomized trial shows that MVP, PIN and CaN can be administered on an outpatient basis with acceptable toxicities. Unfortunately, the three regimens showed an activity significantly lower than that reported in previous single-institution phase II trials.

[Breast cancer today]

Authors, after a short dissertation about evolution, trough out the years, of the diagnosis and the therapy of the mammary carcinoma, specify the leading role of primary prevention. Self palpation and the mammography reduce of about 30% the mortality. Modern pharmacology and radiotherapy allow a surgical preservative approach, produce better esthetic and functional results. Preservative therapy (QUART) also warrants a good quality of life, and allows the excellent control of primary disease.

[Development of a teleradiology system]

PURPOSE

the development of a cost-effective diagnostic system for transmitting high-resolution images on normal phone lines.

MATERIALS AND METHODS

A 486 PC with super VGA screen, 16,800-band external modem and graphic software.

RESULTS

the graphic software allows the PC to be connected to the video output of MRI, CT or US units, or to a video camera as in the case of X-ray units. Image spatial resolution is as high as 1,024 x 768 lines. Transmission times are lower than 45 seconds, corresponding to files of 50-80 kbytes. In 6 months, more than 130 Megabytes (500 images) were transmitted between our diagnostic center and our consultants in northern Italy, France and California.

CONCLUSIONS

this cost-effective teleradiology system allows real-time image transmissions between diagnostic centers all over the world for scientific updating and quick reference purposes. Portable units can be developed.

Neonatal rhabdomyolysis as a presentation of muscular dystrophy

We report a unique presentation of X-linked recessive dystrophy as neonatal rhabdomyolysis. There was induration of the proximal musculature in an otherwise well neonate and striking CK elevation, without myoglobinuria. Muscle biopsy at age 1 year showed dystrophic alterations, and X chromosome analysis showed a deletion within or adjacent to the Duchenne/Becker locus.
