One hundred consecutive isolated limb perfusions with TNF-alpha and melphalan in melanoma patients with multiple in-transit metastases
OBJECTIVE: The aim of this study is to describe the experience with 100
TNF-based ILP for locally advanced melanoma and to determine prognostic
factors for response, time to local progression, and survival. METHODS:
One hundred TNF-based ILPs were performed between 1991 and 2003 in 87
patients for whom local control by surgery of in-transit melanoma
metastases was impossible. In total, 62 iliac, 33 femoral, and 5 axillary
ILPs were performed in mild hyperthermic conditions with 2 to 4 mg of TNF
and 10 to 13 mg of melphalan per liter of limb volume. RESULTS: Overall
response was 95%, with 69% complete response, 26% partial response, and 5%
no change. Complete response rate differed significantly for patients with
IIIA disease versus IIIAB and IV. Local and systemic toxicity was mild to
moderate in almost all cases, with no treatment-related death and one
treatment-related amputation. Five-year overall survival was 32%; local
progression occurred in 55% after a median of 16 months. In complete
response patients, 5-year survival was 42% with local progression in 52%
at a median of 22 months. Response rate and survival were significantly
influenced by stage of disease; (local progression free) survival was
influenced by response rate. CONCLUSIONS: TNF-based ILP results in
excellent response rates in this patient population with unfavorable
characteristics. Response on ILP predicts outcome in patients and reflects
aggressiveness of the tumor
Weekly high-dose cisplatin is a feasible treatment option: Analysis on prognostic factors for toxicity in 400 patients
In the present study we describe the toxicity of weekly high-dose (70-85 mg m-2) cisplatin in 400 patients (203 men, 197 women; median age 54 years) with advanced solid tumours treated in the period 1990-2001 who took part in phase I/II trials, investigating the feasibility and efficacy of weekly cisplatin alone, or in combination with paclitaxel or etoposide. Cisplatin was administered in 250 ml NaCl 3% over 3 h, for six intended administrations. The mean number of administrations was 53 (range, 1-6 administrations). Reasons not to complete six cycles were disease progression (7.5%), haematological toxicity (9%), nephrotoxicity (7%), ototoxicity (2.5%), neurotoxicity (1%), gastrointestinal toxicity (1%), cardiovascular complications (0.5%) or a combination of reasons including noncompliance and patient's request (5.5%). Logistic regression analysis was used to evaluate baseline parameters for prognostic value regarding toxicity. Leukopenia correlated with etoposide cotreatment, and thrombocytopenia with cisplatin dose and prior (platinum-based) chemotherapy. Risk factors for nephrotoxicity were older age, female gender, smoking, hypoalbuminaemia and paclitaxel coadministration. Neurotoxicity >grade I (11% of patients) was associated with prior chemotherapy and paclitaxel coadministration. Symptomatic hearing loss occurred in 15% with anaemia as the predisposing factor. We conclude that weekly high-dose cisplatin administered in hypertonic saline is a feasible treatment regimen
Measurement of hypoxia-related parameters in bronchial mucosa by use of optical spectroscopy.
RATIONALE: Tumor hypoxia has both prognostic and therapeutic consequences for solid tumors. We developed a novel noninvasive technique, differential path-length spectroscopy (DPS), which allows the measurement of hypoxia-related parameters in the superficial microvasculature of tissue. OBJECTIVES: The aim of this study was to measure the microvascular oxygenation of histologically normal endobronchial mucosa and of neoplastic lesions during bronchoscopy using DPS. METHODS: Sixty-four patients with known or suspected malignancies of the lung were studied. One hundred and five endobronchial lesions (38 histologically normal, 37 metaplastic/mild dysplastic lesions, and 30 invasive carcinomas) were detected by white and/or autofluorescence bronchoscopy and measured using DPS. RESULTS: We observed that bronchial tumors are characterized by a lower blood oxygen saturation and a higher blood content than normal mucosa. No differences were observed between normal and metaplastic/mild dysplastic mucosa. CONCLUSION: DPS is a new optical technique allowing the noninvasive study of endobronchial tumor hypoxia
