Somatostatin, retinoids, melatonin, vitamin D, bromocriptine, and cyclophosphamide in chemotherapy-pretreated patients with advanced lung adenocarcinoma and low performance status.

BACKGROUND: We previously reported on an improvement in survival and quality of life in chemotherapy-naïve patients with advanced non-small-cell lung cancer and low performance status (PS) treated with a combination of biotherapeutical agents and cyclophosphamide. In this study, we assessed the survival, clinical status, and toxicity of this multidrug regimen in chemotherapy-pretreated patients with advanced lung adenocarcinoma and low PS. METHODS: Patients with stage IIIB or IV lung adenocarcinoma, who had progressed after prior standard chemotherapy, and with an Eastern Cooperative Oncology Group PS > or = 2, received a daily combination of somatostatin, retinoids, melatonin, vitamin D, bromocriptine, and cyclophosphamide. RESULTS: Twenty-three (23) patients were enrolled. The median age was 59 years (range, 42-75). The PS was 2 and 3 in 73.9% and 26.1% of patients, respectively. The median overall survival (intent-to-treat analysis) was 95 days (range, 19-214). The side-effects were mild, mostly consisting of diarrhea, nausea and vomiting, and drowsiness of Grade 1-2. There was an improvement in both respiratory and general symptoms, which was more evident in patients surviving more than 95 days. CONCLUSIONS: The combined regimen of somatostatin, retinoids, melatonin, vitamin D, bromocriptine, and cyclophosphamide is well tolerated and can improve disease-related symptoms in heavily pretreated patients with late-stage lung adenocarcinoma and poor PS.

Somatostatin, retinoids, melatonin, vitamin D, bromocriptine, and cyclophosphamide in advanced non-small-cell lung cancer patients with low performance status.

BACKGROUND: The prognosis of low performance status (PS) patients with advanced non-small-cell-lung cancer (NSCLC) is dismal. In these patients, we have determined the survival, clinical benefits, and toxicity of a multidrug regimen, based on cyclophosphamide and biotherapeutical agents. METHODS: Patients with a diagnosis of stage IIIB or stage IV NSCLC, no previous surgery or chemoradiotherapy, and an Eastern Cooperative Oncology Group (ECOG) PS equal to or greater than 2 received a daily combination of somatostatin, retinoids, melatonin, vitamin D, bromocriptine, and cyclophosphamide. RESULTS: Twenty-eight (28) patients were enrolled. The median age was 64 years (range, 35-74). The PS was 2 and 3 in 78.6% and 21.4% of patients, respectively. The median overall survival (intent-to-treat analysis) was 12.9 months (range, 1.5-33.5 months), The overall survival rates at 1 and 2 years were 51.2% and 21.1%, respectively. The side-effects were very mild, mostly consisting of diarrhoea, nausea/vomiting, and drowsiness of grade 1-2. Most patients experienced an improvement of both respiratory (cough and dyspnoea) and general (pain, fatigue, and insomnia) symptoms. CONCLUSIONS: Low PS patients with advanced NSCLC may benefit from a combination of somatostatin, retinoids, melatonin, vitamin D, bromocriptine, and cyclophosphamide, in terms of survival and quality of life, with very low side-effects.
