Diagnosis of HCC ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Required to determine the extent of the disease The lesions could be find incidentally or on screeening ultrasound The sequence of tests used to diagnose HCC depends on the size of the lesion
Mass on surveillance ultrasound in a cirrhotic liver Repeat US at 3-4 month interval Two dynamic imaging studies One dynamic imaging technique Typical vascular pattern with one technique Coincidental typical vascular pattern on dynamic imaging Atypical vascular pattern with both techniques Typical vascular pattern on dynamic imaging or AFP > 200 ng/ml Atypical vascular pattern Biopsy Stable over 18-24 months Enlarging Return to standard surveillance protocol (6-12 monthly) Proceed according to lesion size Treat as hepatocellular carcinoma Diagnostic of HCC Non diagnostic Other diagnosis Repeat biopsy or imaging follow-up Change in size/profile Repeat imaging and/or biopsy Negative Positive < 1 cm 1 – 2 cm > 2 cm Suggested algorithm for investigation of a nodule found on ultrasound during screening or surveillance

Factors contributing to early phase (<2 years) recurrence Risk Factors Contributing to HCC  Intrahepatic Recurrence after Hepatectomy Imamura H et al J Hepatol 2003;38:200-207 Hazard ratio 95% CI Microscopic vascular invasion 2.36 1.62 – 3.45 Serum AFP value  ≥ 32 ng/ml 1.83 1.25 – 2.68 Non anatomical resection 1.65 1.13 – 2.40
Is resection only a palliation? Yamamoto et al, Ann Surg 2004 The survival rate of patients with early HCC undergoing Liver Resection decreases 5 years after surgery. This phenomenon is explained by occurrence of second primary HCCs that should be prevented 186 patients with HCC    2 cm treated with curative hepatectomy Early HCC Small advanced HCC

Editor's Notes

  1. La diagnosi di HCC viene generalmente posta sulla base di tecniche di imaging , biopsia e test di laboratorio (livelli di AFP). La scelta e la sequenza degli esami dipende della grandezza della lesione. Per pazienti affetti da epatite B o cirrosi da altra eziologia una massa evidenziata incidentalmente o nel corso di uno screening ecografico ha un’elevata probabilità di rappresentare un HCC. Bruix J, Sherman M. Hepatology 2005 ; 42(5): 1208-1236
  2. Depositato presso AIFA in data 28 ottobre 2009; AN n° IT/ONC/2009/10/0306
  3. Lo schema di trattamento BCLC propone differenti opzioni terapeutiche in base allo stadio del tumore. I pazienti in stadio 0 (HCC molto precoce) sono candidati ideali alla resezione. I pazienti in stadio A presentano tumori in stadio precoce asintomatici e sono idonei a trattamenti radicali (resezione, trapianto, trattamenti percutanei, quali alcolizzazione o radiofrequenza). Lo stadio B (HCC intermedio) include pazienti con HCC multinodulare asintomatico che possono trarre beneficio dalla chemioembolizzazione. Nello stadio C (HCC avanzato) sono inclusi pazienti con tumori sintomatici e/o con invasione vascolare/disseminazione extraepatica. Questa categoria di pazienti è idonea al trattamento con sorafenib. I pazienti appartenenti allo stadio D presentano una prognosi molto sfavorevole, per loro si suggerisce un trattamento sintomatico. Llovet JM et al.

  4. Fra i trattamenti curativi, la resezione chirurgica del tumore consente di ottenere buoni risultati, in termini di sopravvivenza, in pazienti accuratamente selezionati. In questi casi la sopravvivenza a 5 anni può raggiungere il 70%. Un aspetto negativo è rappresentato dall’elevato tasso di ricorrenza, pari al 70% a 5 anni. Bruix J et al .

  7. Le liste di attesa per il trapianto sono lunghe e comportano una crescita del tumore e un relativo aumento delle controindicazioni al trapianto (invasione vascolare, diffusione extraepatica). Negli Stati Uniti viene promosso l’uso del MELD ( Model for End-Stage Liver Disease ) che dovrebbe consentire di priorizzare il trapianto in base al rischio di mortalità di ciascun paziente affetto da patologia epatica dovuta ad abuso di alcol o di origine virale. Tuttavia, inizialmente è stata data priorità troppo elevata a pazienti affetti da HCC, sfavorendo i pazienti non affetti da tumore. Inoltre 1/5 dei pazienti in lista come affetti da HCC, in realtà, non presentavano HCC nel fegato espiantato. Per tale motivo i criteri di eleggibilità sono stati modificati. Il più potente fattore predittivo di ricorrenza del tumore, in assenza di diffusione extraepatica, è l’invasione vascolare macro e microscopica. La possibilità che questo si verifichi è direttamente proporzionale alle dimensioni e al numero del tumore. Bruix J, Sherman M.

  8. L’ablazione percutanea comporta il trattamento diretto delle lesioni dell’HCC attraverso la cute. È la tecnica più utilizzata nei pazienti con HCC in stadio precoce, non idonei alla resezione o al trapianto. La distruzione delle cellule tumorali può avvenire mediante iniezione di sostanze chimiche (etanolo, acido acetico, soluzione salina bollente) o per modificazione della temperatura (radiofrequenza, microonde, laser, crioterapia). L’efficacia della terapia viene valutata mediante TAC dinamica 1 mese dopo la terapia. L’iniezione percutanea di etanolo (PEI) viene eseguita mediante guida ecografica e comporta l’iniezione di etanolo direttamente nel tumore, determinando necrosi. I pazienti possono ricevere più trattamenti in giorni diversi, raramente accompagnata da necrosiin tumori maggiori di 3 cm. La PEI è principalmente impiegata nei pazienti con tumori di piccole dimensioni con presenza di cirrosi. In pazienti con lesioni uniche, di piccole dimensioni (&lt;3 cm) e buona funzione epatica sono stati riportati tassi di sopravvivenza a 5 anni del 40-50%, con tassi di ricadute simili a quelli osservati nei pazienti sottoposti a resezione chirurgica di piccoli tumori. La PEI dovrebbe rappresentare lo standard verso il quale confrontare i nuovi approcci terapeutici. L’ablazione da radiofrequenza (RFA) comporta l’introduzione di una sonda all’interno del tumore (guidata mediante ecografia) per indurre necrosi. Per tumori di diametro &lt; 2 cm ha un’efficacia pari alla PEI, ma richiede un numero inferiore di cicli di trattamento. L’efficacia in tumori di dimensioni &gt; 2 cm è superiore a quella della PEI, tuttavia, presenta costi superiori e un tasso maggiore di eventi avversi (effusione pleurica, sanguinamento peritoneale).

  10. Poor Prognosis for Patients with Advanced HCC Because of its asymptomatic nature, early HCC is difficult to detect and many patients (70% to 80%) present with intermediate or advanced disease at diagnosis 1 These patients have poor prognoses and treatment options are solely palliative Even in patients who undergo potentially ‘curative’ surgery, recurrence rates are high, and 30% to 50% of these patients go on to die from their disease within 5 years 2 Overall survival has been shown to decrease with advancing stage of disease 1,2 Fewer than 10% of patients with advanced HCC can expect to live longer than 5 years 2,3 References 1.

  13. Before the introduction of sorafenib, no survival benefits had been demonstrated for systemic treatments in patients with advanced HCC. No improvements in survival outcome have been demonstrated for hormonal agents such as tamoxifen 1,2 or octreotide. 3 Doxorubicin and cisplatin have some activity when used as single agents; 4 however, recent RCTs of combination chemotherapy have failed to demonstrate efficacy in this population. 5 – 7 This lack of effective systemic therapies for advanced HCC patients represented a considerable unmet medical need. Additional information Loco-regional therapies such as transarterial chemoembolization (TACE) have been shown to prolong survival in patients with unresectable HCC. 8 However, TACE is only suitable for patients with no vascular invasion or extrahepatic spread.

  14. 7 5 5 902 pazienti (pazienti arruolati) sono stati sottoposti a screening; di questi, 602 pazienti rispondevano ai criteri di eligibilità e sono stati randomizzati a sorafenib (n=299) o placebo (n=303). I rimanenti pazienti sono stati esclusi dalla fase di screening a perchè non rispondevano ai criteri di inclusione, per ritiro del consenso informato, per eventi avversi, mancato follow-up , morte. Tra i 602 pazienti randomizzati, 297 e 302 hanno ricevuto almeno una dose di sorafenib o placebo, rispettivamente. Sono state previste due analisi ad interim (170 e 300 eventi) e una finale. La seconda analisi ad interim è stata condotta a ottobre 2006 (321 eventi; 143 per sorafenib e 178 per placebo); sulla base dei risultati ottenuti a febbraio 2007 il DMC ha raccomandato l’interruzione dello studio.

  15. In contrast with most tumor types, risk factors for the development of HCC have been defined. While most predominant risk factor for the development of HCC is cirrhosis, infection with hepatitis viruses B or C is common among patients with HCC. The distribution of hepatitis virus types varies with geographic region, with HBV infection being more predominant among patients from Asia (except Japan) and Africa, and HCV more common among patients from Europe, North America, and Japan. 1 The SHARP trial enrolled patients with risk factors for the development of HCC, including infection with HCV (29%/27%) or HBV (19%/19%) and alcohol use (26%/26%). 2 Depositato presso AIFA in data 28 ottobre 2009; AN n° IT/ONC/2009/10/0306 1.

  18. The SHARP study enrolled primarily patients with advanced HCC (Barcelona Clinic Liver Cancer stage C [BCLC C]; n=497); however, some BCLC B (intermediate) patients (n=105) were also included in the trial. This slide shows the results of a subgroup analysis of the SHARP study in which the overall survival (OS) and time to tumour progression (TTP) were determined according to stage of disease (BCLC B vs. BCLC C) The hazard ratios (HRs) for OS and TTP for sorafenib compared with placebo in each of the subgroups are presented. 1 The results demonstrate that the survival benefit with sorafenib is maintained regardless of stage of HCC, HRs were similar for patients with BCLC B (HR 0.72, 95% CI 0.38, 1.38) and BCLC C (HR 0.70; 95% CI 0.56, 0.89) HRs were consistent with that shown in the overall SHARP population (HR 0.69; 95% CI 0.55, 0.87). 2 As was the case for OS, the prolongation of TTP with sorafenib compared with placebo in the overall SHARP study population was maintained independent of BCLC stage. 1 Median TTP for sorafenib vs. placebo was: 1 BCLC B: 6.9 vs. 4.4 months (HR=0.47; 95% CI: 0.23, 0.96). BCLC C: 4.9 vs. 2.8 months (HR=0.59; 95% CI: 0.45, 0.77). The incidence of adverse events was comparable across BCLC stages and was consistent with that reported for the overall SHARP population. 1,2 Additional information Patients presenting with intermediate (BCLC B) HCC have significantly better OS than patients with advanced disease (BCLC C) The 3-year survival rate for intermediate HCC patients has been reported as 50% versus 8% for advanced HCC patients. 3 References 1.

  22. L’incidenza globale di eventi avversi correlati al trattamento è stata pari all’80% per i pazienti trattati con sorafenib e al 52% per i pazienti trattati con placebo. Gli eventi avversi più frequenti sono risultati sovrapponibili a quelli riscontrati nei precedenti studi di fase II nell’HCC. Gli eventi avversi riportati dai pazienti trattati con sorafenib erano prevalentemente di grado 1 o 2 e comprendevano eventi gastrointestinali, sintomi costituzionali e di natura dermatologica. Gli eventi avversi più rilevanti di grado 3 sono stati diarrea a sindrome mano-piede; non è stato riscontrato alcun evento di grado 4 correlato all’impiego di sorafenib. Llovet JM et al.
