SURGICAL EMERGENCIES IN CANCER MANAGEMENT PROFESSOR V.K. GOLAKAI BSc, MD, ChM, FWACS, FICS, DSc(Med) PRINCESS MARINA HOSPITAL
OBJECTIVES OF PRESENTATION • Overview of tumour emergencies • Common cancer emergencies • Summary of approach to care • Outline basic clinical protocols • Set simple protocols for care • Empower management planning • Establish SOP’s for management
DEFINITION A surgical cancer emergency: • Onset is acute or progressive; • Chief complaint is grave in nature; • Manifestation is cancer-related, • May need urgent surgical care.
FEATURES OF CANCER EMERGENCIES • Aetiology is cancer-related • Condition is a complication of cancer • Hx + PE usually suggest primary cause • Diagnostic delays worsen outcome • Diagnostic tests merely confirmatory • Surgery should not be delayed • A surgical cancer emergency is not a diagnosis, but a disorder with features implicating malignant disease. • Symptom complex or syndrome suggestive and/ applicable to many conditions
DECISION-MAKING IN CANCER EMERGENCIES • Is special admission warranted? • Early vs. delayed intervention • Focused vs. general investigations • ABC’s / Resus before intervention • Consider observation – how long? • Palliative vs. definitive intervention • Resources and methods for management • Prognostication (outcome, counselling)
PILLARS OF DIAGNOSIS • Presenting complaints(1o / 2o) • Signs & symptoms (local, systemic) • Relevant history • Local findings • Systemic status • Fitness for surgical intervention • Timing of intervention • Type and extent of surgical intervention
EPIDEMIOLOGY • Prevalence in elderly > young • More in > 40 (80%), less in < 20 (<5%) • Presentation progressive < acute • Patient in often in distress / toxic • Patient usually very ill / life-threatening • C/S/S confined to cavities (>90%) • Prognosis poor (survival days - < 6/12)
PRESENTING COMPLAINTS/SIGNS 2. Secondary findings / complaints • Pain (gradual onset) – 80% • Confined to abdomen (60%) • Secondary lesions (HIV-A, KS, mets) • Progressive weight loss / cachexia • Anaemia (95% microcytic / hypochromic) • Dysphagia/Dyspnoea/Dysphonia/Distension • Haemoptosis / bloody pleural effusion • Advanced malnutrition (PEM)
PRESENTING COMPLAINTS/SIGNS (2) 1. Recent abdominal distension • Fluid collections (ascites, effusion, blood) • Mass (palpable+/-, mobile, fixed) • Gaseous distension(peristalsis +/-, pain +/-) • Haemoperitoneum (bloody, tinged) • Obstruction vs ileus Perforation • Vomiting (blood, food, bile, faeces) • Recent change in excretory function (BM, urinary incontinence / obstruction)
PRESENTING COMPLAINTS/SIGNS (3) • Haemorrhage (Recent, Overt, Occult) • Upper (Haematemesis, haemoptosis) • Lower (Melena, Haematochezia) • Massive (Burgundy red, clots) • Combined (Mixed colour, liquid/clots) • Haematuria (Initial, mid-stream, terminal) • Haematocolpus • Disseminated intravasc. coagulopathy
PRESENTING COMPLAINTS/SIGNS (4) 4 Miscellaneous signs/symptoms • Met. disorder (80% Acidosis, 20%Alkalosis) • Single / Multi-organ failure Renal 60%, Pulm 20%, CHF 10%, Liver 5%, Pancreas 3%, Skin 2%, CNS 1%) • Malignant lymphoedema Primary – breast, Pemhhigus Secondary – KS, mets • Personality changes (distress, stress anxiety, fear, facies, morbus extremis)
MANAGEMENT APPROACH • High index suspicion (Age, Gender, Hx) • Judicious interpretation of findings • Expeditious diagnosis / management • Basic diagnostics (CXR, AXR, SXR, USG, CT-scan, ECG, Haematology, Biochemistry, Function tests, BGA’s) • Prompt resuscitation (ABC’s, Vasc. access, IVF, Transfusion., Correction of BE/BD) • Maintenance of optimal functional vital signs • Assuring fitness for intervention
MANAGEMENT APPROACH (2) • Management co-existent disease (HTN, DM, CHF, Pulm. / Renal failure, S/MOFs) • Prompt / expeditious timely intervention • Temporary relief symptoms / distress Preparatory for definitive intervention Damage control – “salvage procedure” Diagnostics intervention Comfort • Emergency definitive surgery • Planned delayed definitive surgery
MANAGEMENT APPROACH (3) • Post-operative care/management • Planned re-intervention (2nd look) • Counselling (pre, post, perspective) • Prognosis (< 15% 5YR SR) • Adjuvant care (CT, RT, Combined) • Final rites (dying patient, relatives) • Post mortem and Certificatyion
COMMON DIFFERENTIAL DIAGNOSIS • CA OESOPHAGUS • Laryngeal CA • Lung CA • Gastric CA • Pancreas • Liver / Gallbladder / CBD
COMMON DIFFERENTIAL DIAGNOSIS (2) • CA colon (Lt, Rt, Tr, closed loop) • CA rectum / anus • Musculo-skeletal (SA, Melanoma, KS) • Central Nervous system / Spinal cord • Mets (ascites, haemorrhage, effusion)
COMMON COMPLICATIONS • Haemorrhage (CA, UC, Diverti. dis.) • Peroration (TB, colitis, obstruction) • Intestinal obstruction (ileus, mech.) • Jaundice (stones, inflam. Medical) • Gynae. (ovarian, uterus, cervix) • Fluid collections (ascites, effusions)
COMMON COMPLICATIONS (2) • Lymphoedema (DVT, abscess) • Malnutrition / Cachexia • Pulm. (pneumonia, oedema) • HIVA conditions (KS, TB, Mets) • Peritonitis (1st, 2nd, PID) • Periton. collectn (blood, ascites, pus)
TYPES OF MALIGNANT SURGICAL EMERGENCIES • Acute GIT(>55% of cases) • Acute gynae. (20% of cases) • Acute GUT (10% of cases) • HIVA conditions (8% of cases) • Acute Lung / pulm. (3% of cases) • CNS /spine (2% cases) • Skin / Musculo-skeletal (2% cases) • Mixed / combined (2% cases)
Management outcome • Outcome depends on cancer type • Duration of symptoms and signs • Condition at presentation • Pre-existing / co-morbidities • Age and general physical status • Success of swift management • Type of intervention or none at all • Skill and experience of care-giver
