    • Neoadjuvant therapy involves the preemptive application of chemotherapy prior to the primary treatment, often surgery. The strategic objective is to diminish tumor size or limit the extent of cancer, thereby enhancing the efficacy of subsequent interventions.

    • Adjuvant therapy signifies the administration of chemotherapy subsequent to the primary treatment, such as surgery or radiation. Its purpose is to eradicate residual cancer cells and mitigate the risk of recurrence, thereby augmenting the overall efficacy of the primary treatment.

    • Palliative care assumes a pivotal role, particularly for individuals with advanced or incurable cancer. The emphasis here is on symptom management and the enhancement of overall quality of life, prioritizing comfort over curative intent.

Administration and Timing

 The administration and timing of chemotherapy involve a precise orchestration of infusion methods, durations, and cycles.

Infusion Methods:

Infusion methods encompass the techniques employed for delivering chemotherapy into the patient’s bloodstream. This administration route ensures systemic distribution  and common approaches include intravenous (IV) infusions and in specific cases  subcutaneous infusions.

Continuous, Short, and Intermittent Infusions:

Chemotherapy administration involves varied infusion durations. Continuous infusions entail a steady, uninterrupted delivery of the medication, whereas short infusions are brief, concentrated administrations. Intermittent infusions involve periodic but discontinuous delivery, allowing for recovery between doses.

Multi-day Infusions:

Multi-day infusions extend the administration of chemotherapy over several consecutive days. This method is tailored to specific treatment protocols and ensures a sustained exposure to the therapeutic agents.

Cycles and Timing:

Chemotherapy is often organized into cycles, with each cycle comprising a treatment period followed by a rest period. The timing and duration of these cycles are meticulously determined, considering factors such as the type of cancer, the drugs used, and the patient’s response. This structured approach aims to optimize the therapeutic efficacy while minimizing adverse effects.
