Gemcitabine-Dacarbazine
Administration
• Administered intravenously (IV, meaning through the veins), once every 2 weeks, typically in a hospital setting or chemotherapy day unit.
• Different delivery methods, including cannulas, central lines, PICC lines, or implantable ports, are tailored to individual patient needs.
• A multidisciplinary team, including a cancer doctor, chemotherapy nurse, and specialist pharmacist, oversees the administration.
• Before treatment, a blood sample is taken to ensure safe blood cell levels for chemotherapy.
• You may receive oral or IV drugs prior and after the infusion to prevent nausea.
• It is possible that a subcutaneous injection is required following each cycle. Given at home or at the clinic, it will help boost the immune system.
• Imaging is usually repeated every 4-6 cycles to determine the response.
• The number of cycles of treatment will depend on your tolerance to treatment and your response.
Potential Side Effects & Management
While treatment is being given:
• Allergic Reactions: Signs include feeling hot, itching, rash, dizziness, or swelling. Prompt identification and treatment are crucial.
• Extravasation: Drug leakage outside the vein is critical for sarcoma patients. It can impact surrounding tissues, warranting urgent intervention. Immediate reporting of stinging, pain, redness, or swelling around the vein is essential.
• Pain along the vein: Treatment may cause pain at the infusion site. Promptly inform your nurse or doctor for assessment. Adjustments in drug administration speed or dilution may alleviate pain.
• Facial Flushing: A temporary warm, red sensation during drug administration.
• Flu-like symptoms: Feeling hot, cold, or shivery; headache; aching. These symptoms may last few hours. If severe, contact the hospital.
• Breathlessness: Mild breathlessness after gemcitabine is common and usually improves on its own. Inform your nurse or doctor if you experience this.
Common Side Effects:
• Infection Risk: Given sarcoma treatments’ intensity, reduced white blood cell counts heighten infection risks, necessitating vigilance and timely medical intervention. If you have a fever over 38.3°C, you should advise your medical team or go to the emergency department.
• Bruising and Bleeding: Reduced platelets due to treatment can lead to easy bruising, nosebleeds, or blood in urine/stool. Platelet transfusion might be necessary.
• Anemia: Reduced red blood cells due to treatment can cause anemia. If severe, blood transfusion might be necessary.
• Nausea: Managing this side effect can significantly impact quality of life during treatment.
• Loss of Appetite: Treatment can impact appetite temporarily. Dietary changes may be suggested.
• Diarrhea: Increased bowel activity; more common if you have a stoma.
• Constipation: inability to pass stools as often as usual. Management includes drinking a lot of fluids, increasing fiber consumption, light exercise, and in severe cases, laxatives may be prescribed.
• Effects on Kidneys and Liver: Blood tests monitor kidney and liver function. Maintain hydration and report any unusual symptoms.
• Effects on the Lungs: Notify your doctor of any respiratory symptoms like coughing or breathlessness.
• Fluid build-up: Weight gain or swelling; improves after treatment.
• Sore Mouth & Throat: Treatment may cause sore mouth and throat which can potentially lead to mouth ulcers and increased risk of infection. Maintain oral hygiene; contact your healthcare team for mouthwash or medicines if needed.
• Skin Changes: Rash, sensitivity, discoloration; moisturizing and protective measures are recommended.
• Headache, Muscle or Joint Pain: Post-treatment pain in head, muscles or joints may arise; notify your doctor for pain relief, especially if persistent.
• Feeling tired and sleepy: Common towards the end of treatment; pace yourself. If you’re feeling drowsy, avoid driving or operating machinery.
- Less Common Side Effects:
• Effects on the Brain: Gemcitabine treatment rarely poses a risk of posterior reversible encephalopathy syndrome (PRES), characterized by symptoms like persistent headache, drowsiness, confusion, visual changes, or seizures. Immediate medical attention is crucial, and a full recovery is possible with prompt diagnosis and treatment.
• Effects on the Heart: Regular heart function tests are conducted. Report chest pain, breathlessness, or dizziness to your doctor.
• Sensitivity to the sun: During and after this treatment, individuals should take precautions such as wearing protective clothing, using sunscreen, and avoiding midday sun exposure to reduce sensitivity and risk of sunburn.
Precautionary Measures for Sarcoma Patients
• Blood clot risk: Report symptoms like swelling, breathlessness, or sharp chest pain immediately.
• Communication: Always prioritize informing your healthcare team about ongoing sarcoma treatments, ensuring coordinated care and potential adjustments.
• Vaccinations: Sarcoma patients should be aware of vaccination recommendations, especially considering treatment impacts on immune responses.
• Sex and Contraception: This treatment may impact fertility; discuss and plan contraception strategies with your oncologists.
• Breastfeeding: Avoid while having treatment.
