Partway through a course of chemotherapy, some people are told that from the next cycle onward one drug will be removed while the rest of the regimen continues. Oxaliplatin, a platinum-based drug widely used in gastrointestinal cancers such as stomach and colorectal cancer, is a common example. Its effects accumulate with each cycle, and along with that accumulation, peripheral neuropathy — tingling, cold sensitivity, or numbness in the fingers and toes — tends to build up as well. For that reason, it is not unusual for a care team to stop that single agent before the planned number of cycles is complete while continuing the other drugs, such as a fluoropyrimidine.
Hearing this can sound like treatment is being scaled back or given up on. The reasoning is usually closer to the opposite. Nerve symptoms from platinum drugs are closely related to cumulative dose, and beyond a certain point, recovery after treatment ends can be slow. Once someone is dropping chopsticks or utensils, struggling with buttons, or feeling unsteady because the soles of the feet have gone dull, that difficulty may persist for months after the last cycle. So teams often pause that agent before symptoms interfere with daily function, continue with the remaining drugs, and in some situations reintroduce it later — an approach often described as a stop-and-go strategy, which has been studied in several trials. 'Stopped because it was not working' and 'stopped to manage nerve toxicity' are entirely different situations, and only your own team can tell you which applies to you.
Decisions about dose reduction are based on function, not on how dramatic the sensation feels. Clinicians ask what you can no longer do. Keep a dated note of whether cold water causes a sharp sensation, whether buttons, keys, or utensils have become harder, whether you lose track of where your feet are in dim light, and whether you have stumbled on stairs. Nail changes, including lifting or loss of a toenail, are worth recording too.
A second common situation is having scans done at different facilities depending on scheduling. On CT, slice thickness, the timing of the scan after contrast, positioning, and the scanner itself can all change how a lesion appears. What matters for judging response is not only the current scan but whether it can be compared against the previous one under similar conditions. If a scan was done elsewhere, ask for the raw images (a DICOM disc or USB) as well as the written report, and check in advance whether the treating hospital can register and re-read outside images before your appointment. If a scan is done on a new machine with no prior comparison available, it effectively becomes a new baseline, and statements about 'no change' only become possible from the following scan onward.
'No visible disease on imaging' should also be understood with its boundaries. It means no lesion is identified by the tests used; it does not mean no cancer cells exist at a microscopic level. That is why treatment and surveillance continue, and why the interval to the next scan is set individually based on stage, response, and overall condition.
If you are returning to physical work while numbness remains, add safety to the plan. Reduced sensation means heat, sharp edges, and pressure register late, so burns and cuts can be noticed only after the fact. Use gloves around tools, blades, and heat sources; inspect your hands and feet visually after work rather than relying on feel; and if a toenail is damaged, choose shoes with room at the front and a non-slip sole. When foot sensation is dull, limit work that depends on balance, such as ladders and scaffolding, and avoid moving around in poor light. If the pedals feel different while driving, mention it at your next visit.
Three things are worth preparing for that visit: whether the drug was removed because of nerve symptoms or for another reason; how many cycles remain planned and what findings would change that plan; and where and when the next scan will be done and how to bring the previous images with you.
