But the analysis suggested that, for a large percentage of these patients—those whose cancer was considered to be at low risk of recurrence—3 months of adjuvant chemotherapy may be enough.

How long can you delay chemo?

Short, planned delays in chemotherapy for good-risk GCT patients (less than or equal to 7 days per cycle) appear to be acceptable since they may prevent serious toxicity in this curable patient population. Delays of longer than 7 days are strongly discouraged except in extraordinary life-threatening circumstances.
