Palliative and supportive treatment A.Gonda Motto There is a limit to cure but no limit to care Statistics World: 7.0 Million Hungary: 33.457 (The need for palliation in the group of the patients is about 70 %) What is palliative medicine? Palliative medicine is a treatment form where the psycho-social and physical well-being should be considered PC is not organ-specific Goal of palliation Diagnosis Active treatment Palliation Death Active treatment and palliation is reciprocal. The philosophy of palliation Main goal: QoL Holistic treatment forms which mind the patient itself Treating family members Accepting patient’s mind Definition Palliation: Not the cause itself but symptoms are treated/altered (painkilling, rehydration, constipation etc.) Life expectancy is unimportant Supportation: treatment of the symptoms caused by anticancer treatment (hyperemesis, leukopenia, anaemia etc.) are treated Palliation cont. The two fundamental outcomes of any cancer therapy are prolongation of survival, and quality of life One of the challenges of palliation is that we do not expect to achive cure, nor necessarily complete resoluion of all cancer-associated symptoms The attitude of our health-care It is focusing on the disease instead of the patient Somatic symptoms are minded first of all Psycho-social issues are depressed Communication is insufficient Special aspects of palliative care PC does not necessarily end with the death of the patient Some surviving relatives may need support during bereavement period Those patients whose disease has been controlled need sometimes psycho-social support.

Globally at least 4 million people suffer from cancer pain It is necessary to accurately assess pain Mechanisms of cancer pain 1, nociceptive pain pain arising from somatic soft tissue (The tumor margins are often tender and hypersensitive, mediated by tumour products and host prostaglandines Compression of the host tissues Bone pain Visceral pain Caused by smooth muscle spasm or direct tumor infiltration with an inflammatory response The characteristics of nociceptive pain Pain that is difficult for the patient to localize It can be intense, episodic and associated with other autonomic effects such as sweating, pallor, and nausea Mechanisms of cancer pain cont. Neuropathic pain Nerve compression and infiltration by tumour will initially produce aching pain referred in the distribution of that nerve it may be associated with numbness or motor weakness It has qualities of burning, shooting, or stabbing and may have sudden crescendo episodes with no apparent precipitating cause Often does not respond well to opioid analgesics It is difficult to manage Other aspects of pain 1, Physical causes of pain Primary site of malignancy Metastatic sites 2, Emotional, psychological and social causes of pain Anxiety Stress (diagnosis, treatment etc.) Cancer pain should be considered as being influenced by many factors rather than only by the patient’s physical status. These influences can lower the threshold for pain Assessment of pain The detailed history The longer the patient has experienced pain, the more time is required to unravel the true cause of that pain Measurement of pain there is no overall acceptable way of measuring pain Measuring of pain from one day to the next is a way of establishing whether treatment is effective Visual analogue scales ( grade the pain from 1-10) Diagrams of facial expressions (children) Special problems relating to pain They may arise when the patient experiences severe, unexpected pain Panick attack, patient can be frightened or extremly anxious Background: Bone fracture, spinal cord compression, respiratory distress, intestinal obstruction, cardiac problems Management of cancer pain 1,Sysemic medication 2,Radiotherapy 3, Chemotherapy 4, Surgery 5,Embolisation 6,Ganglion blockade 7, psychotherapy The steps of pain relief strong opioids non-opioids III. step adjuvant medication persistant pain II. step light opioids + non-opioid adjuvant medicines persistant pain I. step non-opioids adjuvant medicines Medications in cancer pain management Non-opioids Light opioids paracetamol, metamizol, acetylsalycilsav, Strong opioids morfin, fentanyl, hydromorphon, oxycodon, methadon adjuvants antidepressants (TCA) antiepileptics neuroleptics anxiolytics steroids codein, dihydrocodein, tramadol, amitriptylin, imipramin, clomipramin carbamazepin, valproát, gabapentin, pregabalin, clonazepam haloperidol, chlorpromazin, levomepromazin alprazolam, diazepam, hydroxyzin dexamethason, methylprednisolon Opioids OPIOIDOK (MORFINSZERŰ HATÁSÚ GY ÓGY SZEREK ) GY ENGE OPIOIDOK (TRAMADOL, CODEIN) Hatás ERŐS OPIOIDOK (MORFIN, FENTANY L, METHADON) Hatás Dózis Dózis Light opioids codein dihydrocodein retard tramadol Side effects: constipation nausea vertigo Strong opioids I. morfin Morphinum HCL inj Sevredol M-Eslon caps MST Continus hydromorphon Palladone SR Jurnista Strong opioids II.

(opioid rotation) Nutritional care When we are ill and our appetite may be poor, food and drink can be a source of conflict and take on a greater importance Giving patients the feeling that they can help with their own well-being through what they eat and drink is important Cachexia A characteristic feature of advanced malignacy is cachexia It presents the clinical picture of weight loss anorexia weakness It leads to progressive loss of mobility, mental apathy and shortened survival Paraneoplastic manifestation which is the result of a host responce to the presence of tumor Symptoms of tumour induced cachexia BMI decrease Asthenia Anorexia Decreased sensitivity to CT and RT Decreased effectiveness of any anticancer treatment Metabolic characteristics of cachexia Negative energy balance While reduced intake is very important, the underlying program lies in the profound changes seen in protein, lipid and carbohydrate metablism as a result of cancer. Increased protein syntesis in the liver (acute phase proteins) Fat stores are progressively depleted Tumor-derived lipolytic factor may be partly responsible for fat breakdown Anaerobic glycolysis in tumor tissue produces lactic acid Increased gluconeogenesis in the liver Reduced insulin response Other factors in cancer malnutrition Dysphagia Gastrointestinal obstruction Nausea Vomiting Mucositis Enteritis Treatment of tumour induced cachexia Steroid Megestrol acetate NSAID Thalidomide Canabinoids Loss of 30 % of body weight could be fatal Nausea and vomiting Affecting 40-70% of patients It can be very distressing It may be difficult to control Nausea Associated with autonomic symptoms (cold sweats, pallor, salivation, tachycardia,) Often more unpleasant than vomiting Features of vomiting Concomitant nausea Nature of vomit Timing of vomit Abdominal distension Constipation Urinary symptoms Headache on waking Dyspepsia Simple „non-drug” measures Avoidance of food smells or unpleasant odors Relaxation Acupressure Acupuncture Causes of vomiting Gastrointestinal Upper: sore tongue, candidal infection, difficulty expectorating, oesophagitis, carcinoma of the oesophagus Mid: peptic ulcer, gastritis, carcinoma of the stomach, pancreas tumor, gall bladder disease, bowel obstruction Lower: constipation, bowel obstruction Hepatic disease Causes of vomiting cont.

Improving WBC with using colony stimulants (GMCSF, GCSF) Transfusions-erythropoetins Thrombopoetins Antibiotics Wound healing Aphtosis, mucositis Nausea, vomiting CSF GCSF: Neupogen, Neulasta WBC count will be enhanced in 2-3 days Should be delivered if WBC is less than 200/ul Cease it if WBC is more than 1500/ul Advantage : shorter improves WBC count than Leucomax Disadvantage: No influence on PLT count and RBC count CSF Could be delivered preventively, but ! 1. Chemotherapy 2. CSF on day 2. Dosage. 5ug/kg/day Antibiotics in a preventive way ? Erythropoetins Causes of anaemia : bleeding, haemolysis, decrease of EPO – level Treatment forms : transfusions vs EPO EPO binds to receptor like IL-2, GCSF and other cytokines Erythropoetins There are 2 preparations, ie. alfa and beta S.c. and iv. forms – both effective Initial dosage : 100 U/kg or 5000 U / day or 40.000 U / week Indications : cancer related anaemia , CT induced anaemia, Adverse effects : Blood pressure elevations, seizures Thrombopoetins 2 forms : in clinical trials Increases the size and number of megakaryocytes, stimulates nucleic polyploidy, upregulates platelet markers Dosing : not yet defined Indication : thrombopenia, bone narrow transplant Adverse events: few side effects, cardiorespiratory disease? Nausea and vomiting Variations : Acut emesis – in the first 24 hour of treatment Delayed emesis – between 2-7 days of treatment Anticipatory vomiting – before treatment – reflexogen activitiy Treatment forms : HT3 blockers, steroids, anxiolytics, psychomimetics During palliation Do not overtreat the patient! Holistic treatment is necessary Improve the quality of life Do not prolong suffering Help the family members
