In order to study the usefulness of treatment with vinblastine (VLB) in the prevention of cancer metastasis in squamous cell lung cancer, 50 patients with locoregional disease were randomized to receive either locoregional RT alone (group A) or a weekly intravenous bolus injection of VLB (6 mg/m2) concurrently with and after locoregional radiotherapy (RT) (55 Gy in 6 weeks) until the appearance of metastases (group B). Neither the incidence of death with metastases, metastasis-free survival (MFS) nor overall survival (S) were significantly affected by treatment with the drug. However, due to the limited number of patients in each group, the power of the statistical test was such to allow only the detection of differences in MFS and S to or more than 80 per cent at the P = 0.05 level. Local tumor response was significantly superior in group B (P less than 0.05). Acute toxicity (dysphagia, myelosuppression) during RT was significantly worse in group B. During long-term therapy with VLB, mild polyneuropathy developed in the majority of patients in group B. Furthermore, seven patients discontinued treatment with VLB during maintenance due to compliance (4) and excessive neurotoxicity (3). This treatment schedule with VLB is not recommended for patients with locoregional squamous cell lung cancer as significant toxicity is present during and after RT and significant increase in MFS and S is lacking. Because of an apparent increase in local response, the combination of VLB and RT merits further investigation in those tumors where local tumor control is crucial.

PMID:Is adjuvant treatment with vinblastine effective in reducing the occurrence of distant metastasis in limited squamous cell lung cancer? A randomized study. 333 80

Approximately 50% of patients with primary lung cancer have distant metastasis at the time of their first visit, but gastric metastasis is a rare occurrence. Herein, we report a case of progressive dysphagia as the first symptom and the final diagnosis of primary lung squamous cell carcinoma metastasis. A 61-year-old man was diagnosed with a solitary left lower lobe tumor and a solitary carcinoma of gastric cardia suspected to be metastatic or malignant stromal tumors. After surgical resection, the final diagnoses were primary differentiated squamous cell lung cancer, metastatic squamous cell carcinoma of the stomach, and secondary lymph node metastasis. Gastrointestinal metastasis should be suspected in lung cancer patients with gastrointestinal symptoms. Gastric cancer metastasis from lung cancer is most likely the result of the aspiration of cancer cells containing sputum into the stomach.
