Lung carcinoma

Biological Activity. The maytansinoids possess antitumor activity, particulady against P 388 lymphocytic leukemia, B 16 melanocarcinoma, and Lewis lung carcinoma. A number of semisynthetic esters of maytansinol have been prepared and exhibit good antileukemic activity (52,255). The maytansides lack antitumor activity, indicating that the ester at C-3 is a requirement for activity (50,52). The carbinolamide also appears to be necessary for...

Poly(DL-lactide) was used as the excipient in microspheres of CCNU, a nitrosourea, prepared by a solvent evaporation procedure (96,97). PLA-CCNU microspheres 3.0 pm in diameter were injected i.v. and leukemia cell survival was determined by spleen colony assay. A 100-fold decrease in leukemia cell survival was observed with the microspheres in both spleen and liver compared to untreated controls. Promising results were also obtained with Lewis lung carcinoma in mice. These studies showed that 2- to 4-ym microspheres were preferentially targeted to the lungs. 

A cytotoxic alkaloid has been isolated from the filamentous species Hapalosi-phon forUinalis strain V-3-1. This isolate was made from soil samples collected in the Marshall Islands in 1981. This strain produces the lipophilic compound hapalindole A, which has a broad range of antialgal and antimycotic activity (9). OscUlatoria acutissima strain B-1, isolated from a freshwater pond in Oahu, was found to produce two novel macrolide compounds termed acutiphycin and 20, 21-didehydroacutiphycin. These macrolides show cytotoxicity (KB and NIH/3T3) and antitumor activity (Murine Lewis lung carcinoma) (10). 

ACTH-secreting non-pituitary tumors (ectopic ACTH syndrome)—15% of cases of endogenous Cushing s syndrome usually from small cell lung carcinoma, bronchial carcinoids, pheochromocytoma, or thymus, pancreatic, ovarian, or thyroid tumor. The tumor is usually disseminated (difficult to localize).
