About Oncology Treatments
Oncology treatments encompass a range of systemic therapies designed to halt the growth of malignant cells and, when possible, eradicate tumors. In Singapore, these medications are prescribed for solid tumours such as breast, lung, colorectal, and gastric cancers, as well as haematological malignancies including lymphomas and leukemias. The therapeutic arsenal includes cytotoxic chemotherapy, molecularly targeted agents that interfere with specific oncogenic pathways, and immunotherapies that enlist the patient’s immune system to attack cancer cells. Clinicians select a regimen based on cancer type, stage, molecular profile, patient performance status, and prior treatment history. Combination protocols often integrate agents from different classes to maximise tumouricidal activity while managing resistance. The goal of oncology treatment varies from curative intent in early-stage disease to disease control and symptom palliation in advanced cancer. Common therapeutic classes within this category are alkylating agents, antimetabolites, taxanes, tyrosine-kinase inhibitors, monoclonal antibodies, and checkpoint inhibitors.
Understanding Oncology Treatments
Oncology treatments refer to systemic drug therapies administered orally, intravenously, or subcutaneously to treat malignant disease. They address primary tumours, micrometastatic disease, and in many cases, recurrent cancer. The principal mechanisms are (1) direct DNA damage or mitotic disruption by cytotoxic chemotherapy, (2) inhibition of oncogenic signalling pathways via targeted therapy, and (3) modulation of immune checkpoints or activation of immune effector cells through immunotherapy. In Singapore, the Health Sciences Authority (HSA) classifies these agents as prescription-only medicines, requiring a licensed prescriber’s order and, for many targeted and immunologic agents, a documented indication on the national electronic health record.
The category spans several sub-domains. Chemotherapy includes traditional cytotoxics such as alkylating agents, antimetabolites, and microtubule inhibitors. Targeted therapy comprises small-molecule tyrosine-kinase inhibitors (TKIs) and monoclonal antibodies that block growth factor receptors or downstream signalling proteins. Immunotherapy features checkpoint inhibitors (PD-1/PD-L, CTLA-4 blockers) and newer cellular therapies. Treatment philosophy balances maximal tumour control against toxicity, aiming for complete remission when feasible, or durable disease stabilization with acceptable quality of life. Therapeutic goals are communicated through multidisciplinary tumour boards, ensuring that each regimen aligns with the patient’s overall care plan.
Common Medications in This Category
Major Therapeutic Subcategories
- Alkylating Agents (e.g., cyclophosphamide, ifosfamide): Form covalent bonds with DNA, causing cross-links that prevent replication and trigger apoptosis. Frequently combined with other cytotoxics in breast and lymphoma protocols.
- Antimetabolites (e.g., 5-fluorouracil, capecitabine, methotrexate): Mimic natural substrates required for DNA synthesis, halting tumour cell proliferation. Widely used in gastrointestinal and head-and-neck cancers.
- Taxanes (e.g., paclitaxel, docetaxel): Stabilise microtubules, obstructing mitotic spindle formation and leading to cell-cycle arrest. Integral to first-line regimens for lung and ovarian cancers.
- Tyrosine-Kinase Inhibitors (TKIs) (e.g., erlotinib, osimertinib, imatinib): Block intracellular enzymes that transmit growth signals from mutated receptors such as EGFR or BCR-ABL. Their oral administration permits chronic dosing for chronic myeloid leukaemia and selected non-small cell lung cancers.
- Monoclonal Antibodies (e.g., trastuzumab, bevacizumab): Bind extracellular domains of receptors like HER2 or VEGF, preventing ligand interaction and downstream signalling. Used in HER2-positive breast cancer and metastatic colorectal cancer, respectively.
- Checkpoint Inhibitors (e.g., pembrolizumab, nivolumab): Release the brakes on T-cell activity by blocking PD-1 or PD-L1, facilitating immune-mediated tumour destruction. Indicated for melanoma, renal cell carcinoma, and several refractory solid tumours.
These classes form the backbone of modern oncology practice, offering clinicians a toolkit to tailor treatment to molecular diagnostics and patient tolerance.

Express shipping delivers within approximately seven days; standard shipping arrives within three weeks. Temperature-controlled containers are employed for agents requiring refrigeration, ensuring therapeutic integrity upon arrival.
Treatment Considerations & Safety
Oncology medications demand careful medical supervision because of narrow therapeutic windows and potential for severe adverse effects. Baseline assessments-including complete blood counts, liver and renal function tests, and, where applicable, profiling-guide dosing and monitoring. Common interaction patterns involve cytochrome P450 substrates; for example, many TKIs are metabolised by CYP3A4, so co-administration with strong inhibitors or inducers can alter plasma concentrations. Contraindications frequently include pregnancy, uncontrolled infections, or pre-existing organ dysfunction.
Treatment duration varies: curative protocols may span several cycles over months, while maintenance immunotherapy can continue for years if disease remains controlled. Regular imaging and laboratory monitoring detect early toxicity, allowing dose adjustments or supportive interventions such as growth-factor support for neutropenia. Patient education on symptom reporting-fever, mucositis, neuropathy-is essential to prevent complications.
Frequently Asked Questions
-
What determines the choice between chemotherapy, targeted therapy, and immunotherapy? Selection hinges on tumour histology, stage, molecular markers, and previous treatment exposure. Molecular testing may reveal actionable mutations that make targeted agents preferable, while immunotherapy is considered when tumours express high PD-L1 or exhibit microsatellite instability.
-
Can oral targeted agents replace intravenous chemotherapy? In certain cancers, oral TKIs have become standard first-line options, offering comparable efficacy with the convenience of home administration. However, many solid tumours still require intravenous cytotoxics for maximal tumour reduction.
-
How are chemotherapy doses calculated? Dosing commonly uses body surface area (BSA) derived from height and weight, or based on renal function for agents cleared renally. Precision dosing minimizes toxicity while preserving antitumour activity.
-
Do immunotherapy drugs work for all cancer types? Response rates differ markedly across tumour types. checkpoint inhibitors show high activity in melanoma and Hodgkin lymphoma, moderate activity in lung and renal cancers, and limited efficacy in colorectal cancers lacking mismatch repair deficiency.
-
What are the most of TKIs? Dermatologic rash, diarrhoea, and mild elevations in liver enzymes are frequent. Some agents cause hypertension or cardiac QT prolongation, necessitating periodic ECG and blood pressure monitoring.
-
Is it safe to take supplements while receiving oncology treatment? Certain supplements, such as high-dose antioxidants or St. John’s wort, can interfere with drug metabolism or diminish therapeutic effect. Always disclose any over-the-counter products to the treating oncologist.
-
How does the body recover after a chemotherapy cycle? Hematologic recovery typically occurs within 7-14 days, during which white blood cells and platelets rebound. Supportive care, including anti-emetics and hydration, aids tissue healing and reduces infection risk.
-
Can pregnancy be safely managed while on targeted therapy? Most targeted agents are teratogenic and contraindicated during pregnancy. Effective contraception is required for women of childbearing potential throughout treatment and for a defined washout period after cessation.
-
What lifestyle adjustments improve outcomes with immunotherapy? Maintaining a balanced diet, regular moderate exercise, and adequate sleep support immune function. Avoiding smoking and limiting alcohol intake further reduce immune suppression.
-
Do I need to stay at the hospital for infusion therapies? Intravenous chemotherapy and immunotherapy are usually administered in outpatient infusion centres. Observation periods range from 30 minutes to several hours, depending on the drug’s infusion-related reaction profile.
-
How often should imaging be performed to assess treatment response? Radiologic evaluation is typically scheduled every 2-3 months for solid tumours, aligning with treatment cycles. Response criteria such as RECIST guide decisions on continuing, modifying, or switching therapy.
