    This is often a sign that the plant needs more light. Plants will stretch in response to this. This article will give you more information on the care of these: https://www.gardeningknowhow.com/houseplants/dumb-cane/growing-dumbcane-dieffenbachia.htm

    Propagation of the leaf stem is unlikely. It has to have some of the stem tissue where it was attached to the main stem to propagate. But don't worry, this is a fast growing plant. It will need to have its main stem pruned back regularly. The top cuttings from pruning will root easily in water or damp soil or in the base of the plant.

    Long spindling stems would indicate that there is a lack of light to the plant. Rot would show, usually, as brown leaf tips, or black, brown, or yellow spots.

    This is common with too little light. You can try giving it just a small bit of direct light in the morning, or get a horticultural grade light to supplement. 100 watts will be plenty for the plant. They don't need much more than that.

    I think, initially, there was some nutrient deficiencies some shock due to the move, and that once the soil was changed it may have stayed a little too moist for too long. It seems to have a fungal infection at this point.

    I would add dolomitic lime and wettable sulfur to the soil. This can help keep the pH leveled out, as well as keeping fungal infections at bay, respectively.

    It seems that you have done well with the plant, since it has been around for so long. I just think that it was stressed very suddenly by many factors.

    Follow my recommendations, and you can see a recovery as long as the infection has not progressed too far. It will not be fast, and the old growth will not recover, but the new growth should come out looking more normal.

    Yes, it's normal for dieffenbachias to become large and unruly eventually, but you can prune them back. When pruning, you can remove up to 1/3 of the plant's total size at any one time. You can entirely remove individual stems, or you can cut a stem back part way to encourage more bushy growth close to the center of the plant.
