H.-J. Senn Adjuvant Chemotherapy (ACT) of breast melanoma has now emerged as one of many arguable su):>jects in medical and in addition experimental oncology. pushed by means of growing to be frustration approximately stagnating therapy charges in breast melanoma [1,4] and encouraged through stylish demonstration of hugely healing results of adjuvant systemic remedy in animal types [6, eleven] and in numerous early life neoplasias [15], researchers brought ACT to the first therapy of breast melanoma with nice desire a few 15 years in the past. After a primary wave of remoted "historic" trials with commonly restricted yet in a single case notable good fortune [5, 9], a moment new release of ACT experiences used to be initiated by way of NSABP investigators and oncology facilities in Europe [2, 6, 13]. those trials have been good carried out statistically and diagnostically, and all within the early Seventies integrated a surgical regulate arm. Early and intermediate helpful results on relapse-free survival (RFS) after 2-3 years median commentary time then triggered an entire sequence of ACT stories in breast melanoma. those "third-gener­ ation" reports often seemed a few optimistic impression of ACT as a given truth, losing surgical regulate regimens and evaluating diverse ACT regimens, optimistically in a potential, randomized manner 1984 Fig. 1. The mushrooming of adjuvant experiences in breast melanoma XII creation [reviews in three, 14]. The "mushrooming" of ACT reports in breast melanoma over the past 10 and particularly five years is established in Fig. 1, and it will get fairly bulky even for the insider to maintain on best of the multitude of occasionally conflicting data.

Example text

Both pre- and postnatal brain cells are , however , deficient with regard to the enzymatic removal of 0 6-alkyldGuo from DNA [60, 73]. It appears , therefore , that in this cell system malignant transformation (or some as yet undefined stage of the process of malignant transformation preceding the ultimate development oftumorigenic phenotypes) is associated with the activation of 06-alkyldGuo repair. Since these 06-alkyldGuo repair-proficient neuroectodermal tumor cells were maintained and analyzed in cell culture , it should , however , also be investigated whether the expression of DNA repair enzymes may be modified by the continuous cultivation of (malignant) cells on plastic surfaces .

Follow-up data have not yet been reported even though, as noted, the program began in 1973. There were 4,443 breast carcinoma recorded at the Data Management Center as of September 1981 (3,557 carcinomas were detected by the BCDDP and 886 were detected outside the project). Carcinomas were detected in 1,082 (32%) women who had not reached the age of 50. Of the cancers detected, 782 were noninfiltrating (in situ carcinoma); 371 were infiltrating and measured less than 1 cm in diameter. The rest were infiltrating carcinomas equal to or greater than 1 cm in diameter, or their size was not recorded.

Basically we remain confronted with the fact that no form of cytocidal chemical treatment can at present be targeted exclusively to the malignant cells contained within the large number of normal cells in the organism (~ 109 malignant cells in 1 g of tumor tissue vs ~ 5 X 1013 normal cells, in the adult). This limits the applicable dose of a cytotoxic agent to a level compatible with the survival of sufficient numbers of (stem) cells of the most critical normal-cell systems (hemopoietic and immune system, intestinal epithelia).
