Background

Pancreatic neuroendocrine tumours (PNETs) are rare neoplasms of the pancreas. Real-world treatment outcomes in Asia are seldom reported. The aim of this study was to provide the real-world treatment outcomes of PNETs at a single tertiary cancer centre in Hong Kong over an 18-year period.

Materials and methods

This was a retrospective cohort study that recruits patients with local or metastatic PNETs treated at Prince of Wales Hospital, Hong Kong between 2005 and 2023. Five-year overall survival (OS), progression-free survival (PFS), recurrence-free survival (RFS) of the surgical cohort, and survival outcomes in patients with metastatic disease were summarized.

Results

A total of 98 patients were recruited (median age: 59 years, 51% male). Among them, 18 patients (18.4%) had functioning tumours, of which majority were insulinoma (72.2%). Most tumours (64.8%) were classified as grade 1 disease. More than 80% of patients had early-stage disease on presentation, with only 14 patients presented with stage IV disease. Five-year OS for the entire cohort was 88.4% and the 5-year PFS was 73.7%. Older age [hazard ratio (HR) 1.06, 95% confidence interval (CI) 1.00-1.13, P = 0.04] and larger tumour size (HR 1.20, 95% CI 1.00-1.44, P = 0.05) were associated with worse OS, whereas patients with metastatic disease had a shorter PFS (HR 7.95, 95% CI 2.55-24.8, P < 0.001). In the cohort treated with curative surgery, metastatic disease (HR 7.49, 95% CI 1.40-40.0, P = 0.018) and tumour grade (HR 8.03, 95% CI 1.58-40.8, P = 0.012) were associated with worse RFS. Microscopic margin involvement did not influence RFS in patients treated with curative surgery. In the 20 patients who received systemic therapy, everolimus showed a trend towards improved PFS compared with chemotherapy (5-year PFS: 46.9% versus 16.7%).

Conclusion

Patients with PNETs in Hong Kong have early presentation and excellent prognosis with most patients being eligible for curative surgery reaching 90% of 5-year OS.

胰腺神经内分泌肿瘤（PNETs）是一种罕见的胰腺肿瘤。亚洲的实际治疗结果很少被报道。本研究的目的是提供PNETs在香港单一三级癌症中心18年期间的实际治疗结果。材料和方法本研究是一项回顾性队列研究，招募2005年至2023年间在香港威尔斯亲王医院接受治疗的局部或转移性PNETs患者。总结了手术队列的5年总生存期（OS）、无进展生存期（PFS）、无复发生存期（RFS）以及转移性疾病患者的生存结局。结果共纳入98例患者（中位年龄59岁，男性占51%）。其中功能性肿瘤18例（18.4%），以胰岛素瘤居多（72.2%）。大多数肿瘤（64.8%）被归类为1级疾病。超过80%的患者在就诊时为早期疾病，只有14例患者表现为IV期疾病。整个队列的5年OS为88.4%，5年PFS为73.7%。年龄较大[危险比（HR） 1.06, 95%可信区间（CI） 1.00-1.13, P = 0.04]和肿瘤大小较大（HR 1.20, 95% CI 1.00-1.44, P = 0.05）与较差的OS相关，而转移性疾病患者的PFS较短（HR 7.95, 95% CI 2.55-24.8, P < 0.001）。在接受根治性手术治疗的队列中，转移性疾病（HR 7.49, 95% CI 1.40-40.0, P = 0.018）和肿瘤分级（HR 8.03, 95% CI 1.58-40.8, P = 0.012）与较差的RFS相关。显微切缘受累不影响根治性手术患者的RFS。在接受全身治疗的20例患者中，与化疗相比，依维莫司显示出改善PFS的趋势（5年PFS: 46.9%对16.7%）。结论香港PNETs患者临床表现较早，预后较好，大多数患者的5年总生存率达到90%。

Hepatocellular carcinoma (HCC) is the most common primary liver cancer, with a rising global incidence. Prognosis in HCC remains poor, particularly in patients presenting with macrovascular invasion (MVI), which is associated with high rates of hepatic decompensation, diffuse disease progression, and a median survival of only 2-5 months without treatment. Management of HCC with MVI is complex, requiring multidisciplinary and multimodality approaches. While surgery and transplantation may be considered in select cases, systemic therapy with immunotherapy-based regimens currently represents standard of care. Limitations due to complications with MVI often makes optimal treatment challenging. Advances in modern radiotherapy, particularly stereotactic body radiotherapy (SBRT), have established it as a safe and effective local therapy capable of delivering ablative doses while sparing normal liver tissue. Retrospective series and prospective trials have demonstrated that SBRT provides high local control rates, objective response rates exceeding 50%, and survival benefits when combined with systemic or locoregional therapies alone. SBRT has also shown promise in improving liver function and palliating symptoms in patients with poor hepatic reserve. Emerging evidence suggests synergistic effects when combined with immunotherapy or transarterial therapies, with ongoing studies poised to clarify its role in modern treatment paradigms. Collectively, data support the use of SBRT as a crucial tool in the multidisciplinary management of HCC with MVI, offering durable local control, symptom relief, and the potential to enhance systemic therapy efficacy.

肝细胞癌（HCC）是最常见的原发性肝癌，全球发病率呈上升趋势。HCC的预后仍然很差，特别是出现大血管侵犯（MVI）的患者，这与肝功能失代偿率高、弥漫性疾病进展以及不治疗的中位生存期仅为2-5个月有关。肝细胞癌合并MVI的治疗是复杂的，需要多学科和多模式的方法。虽然在某些情况下可以考虑手术和移植，但目前以免疫治疗为基础的全身治疗是标准的治疗方案。由于MVI并发症的限制往往使最佳治疗具有挑战性。现代放射治疗的进展，特别是立体定向体放射治疗（SBRT），已使其成为一种安全有效的局部治疗，能够提供消融剂量，同时保留正常肝组织。回顾性系列和前瞻性试验表明，SBRT具有较高的局部控制率，客观缓解率超过50%，并且在与全身或局部治疗单独联合时具有生存益处。SBRT还显示出改善肝功能和缓解肝储备不良患者症状的希望。新出现的证据表明，与免疫治疗或经动脉治疗联合使用时具有协同作用，正在进行的研究准备阐明其在现代治疗范例中的作用。总的来说，数据支持将SBRT作为HCC合并MVI的多学科管理的关键工具，提供持久的局部控制，症状缓解，并有可能提高全身治疗的疗效。

Background

Zolbetuximab plus chemotherapy improves survival in patients with human epidermal growth factor receptor 2 (HER2)-negative, claudin 18 (CLDN18)-positive advanced gastric cancer (AGC), which is defined as ≥75% of tumor cells with moderate-to-strong membranous staining. Whether semiquantitative expression within this range influences treatment outcomes is unknown.

Patients and methods

This single-center retrospective study evaluated patients with AGC treated with zolbetuximab plus chemotherapy between July 2024 and September 2025. Tumors were independently reviewed by three pathologists and categorized as having moderate (75%-94%) or high (95%-100%) CLDN18 expression. Survival, response, and safety were compared across expression levels.

Results

Fifty-one patients were included in the study. Baseline characteristics were similar across the groups. The median progression-free survival was 6.7 months in both expression groups, and the median overall survival was not reached. The objective response rates were 62.5% and 71.4%, and the disease control rates were 87.5% and 85.7% in the moderate and high expression groups, respectively. The depth of response (−33.6% versus −45.8%) and early tumor shrinkage (43.8% versus 71.4%) differed modestly. The profile of treatment-related adverse events was similar across the expression groups. Specimen type (biopsy or surgical resection) had no apparent impact on treatment outcomes.

Conclusions

Within the approved CLDN18-positive threshold, the semiquantitative staining proportion showed no detectable differences in the efficacy or safety of zolbetuximab plus chemotherapy.

zolbetuximab联合化疗可提高人表皮生长因子受体2 （HER2）阴性，CLDN18 （CLDN18）阳性的晚期胃癌（AGC）患者的生存率，AGC定义为≥75%的肿瘤细胞具有中至强膜性染色。该范围内的半定量表达是否影响治疗结果尚不清楚。患者和方法本单中心回顾性研究评估了2024年7月至2025年9月期间接受唑仑妥昔单抗联合化疗的AGC患者。肿瘤由三位病理学家独立审查，并将其分类为中度（75%-94%）或高（95%-100%）CLDN18表达。在不同的表达水平上比较生存、反应和安全性。结果共纳入51例患者。各组的基线特征相似。两组患者的中位无进展生存期均为6.7个月，中位总生存期均未达到。中、高表达组的客观有效率分别为62.5%和71.4%，疾病控制率分别为87.5%和85.7%。反应深度（- 33.6%对- 45.8%）和早期肿瘤缩小（43.8%对71.4%）略有差异。治疗相关不良事件的概况在表达组之间相似。标本类型（活检或手术切除）对治疗结果无明显影响。结论在批准的cldn18阳性阈值内，半定量染色比例显示唑苯妥昔单抗联合化疗的疗效和安全性无明显差异。

Background

The findings of the prospective, real-world REFINE trial supported the safety and efficacy of regorafenib reported in the phase III RESORCE study, in a broader population of patients with unresectable hepatocellular carcinoma (HCC). This post hoc analysis evaluated patient subgroups based on liver function, liver cancer stage, and prior treatment.

Patients and methods

Patients were analyzed by subgroups based on liver function [Child–Pugh (CP)–B/B7], prior treatment [prior orthotopic liver transplant (pOLT), transarterial chemoembolization (TACE)/transarterial radioembolization (TARE)], and Barcelona Clinic Liver Cancer (BCLC) stage. The primary objective was to evaluate the safety of regorafenib. Secondary objectives included effectiveness endpoints of overall survival (OS) and duration of treatment. All analyses were descriptive with no adjustment for confounders.

Results

A total of 1005 patients were evaluable (overall population). In patients with CP–B (n = 123) compared with the overall population, the incidence of grade ≥3 (28% versus 27%) and serious drug-related treatment-emergent adverse events (TEAEs) was similar (11% versus 9%), whereas TEAEs leading to permanent discontinuation of regorafenib were more common (28% versus 16%). In patients with prior TACE (n = 584), the incidence of TEAEs was generally similar to patients without prior TACE (n = 421) and the overall population (92%, 91%, and 92%, respectively). Median OS was 12.3-19.3 months across all subgroups except CP–B/B7 (6.4/6.7 months).

Conclusions

This subgroup analysis of REFINE provides further evidence on the safety and effectiveness of regorafenib demonstrated in RESORCE, in underrepresented subgroups (CP–B, BCLC stage B/C, pOLT) and in those previously treated with TACE/TARE.

前瞻性、现实世界的REFINE试验结果支持reorafenib在更广泛的不可切除肝细胞癌（HCC）患者人群中的安全性和有效性。这项事后分析评估了基于肝功能、肝癌分期和既往治疗的患者亚组。患者和方法根据肝功能[Child-Pugh (CP) -B /B7]、既往治疗[既往原位肝移植（pOLT）、经动脉化疗栓塞(TACE)/经动脉放射栓塞（TARE）]和巴塞罗那临床肝癌（BCLC）分期进行亚组分析。主要目的是评估瑞非尼的安全性。次要目标包括总生存期（OS）和治疗时间的有效性终点。所有的分析都是描述性的，没有对混杂因素进行调整。结果1005例患者（总体）可评估。在CP-B患者（n = 123）中，与总体人群相比，≥3级（28%对27%）和严重药物相关治疗不良事件（teae）的发生率相似（11%对9%），而导致瑞非尼永久停药的teae更为常见（28%对16%）。在有TACE病史的患者（n = 584）中，teae的发生率与没有TACE病史的患者（n = 421）和总体人群（分别为92%、91%和92%）大致相似。除CP-B /B7（6.4/6.7个月）外，所有亚组的中位OS为12.3-19.3个月。REFINE的亚组分析进一步证明了reorafenib在resource、代表性不足的亚组（CP-B、BCLC B/C期、pOLT）和先前接受过TACE/TARE治疗的患者中的安全性和有效性。

Early- and advanced-stage MSI-H non-colorectal cancers: best management and challenges in 2025 早期和晚期MSI-H非结直肠癌：2025年的最佳管理和挑战

ESMO Gastrointestinal Oncology

Pub Date : 2026-01-22 DOI: 10.1016/j.esmogo.2025.100296

R. Fazio, M. Ambrosini, A. Raimondi, C.C. Pircher, C. Leli, C. Sciortino, S. Marchesi, C. Damonte, C. Villa, C. Silvestri, F. Manoni, G. Gronchi, F. Pietrantonio

Gastrointestinal malignancies account for the vast majority of tumours within the microsatellite instability-high (MSI-H)/mismatch repair-deficient (dMMR) phenotype. Over the past decade, evidence on the prognostic and predictive role of MSI-H/dMMR status has steadily accumulated, and immune checkpoint inhibitors (ICIs) are now considered the cornerstone of treatment for all patients with advanced MSI-H/dMMR cancers. However, in non-colorectal tumours the available evidence is less robust, raising important challenges, such as defining the optimal therapeutic regimen across different treatment lines and establishing the appropriate duration of therapy. More recently, the efficacy of ICIs has also been demonstrated in localized disease, prompting new questions regarding their integration into curative-intent strategies, such as the risk of overtreatment given the favourable prognosis of early-stage tumours, the role of nonoperative management, the optimal treatment regimen, and schedule. In this review, we summarize the available literature and the evidence supporting treatment strategies for patients with early- and advanced-stage MSI-H/dMMR non-colorectal cancers.

胃肠道恶性肿瘤占绝大多数微卫星不稳定性高(MSI-H)/错配修复缺陷（dMMR）表型的肿瘤。在过去的十年中，关于MSI-H/dMMR状态的预后和预测作用的证据不断积累，免疫检查点抑制剂（ICIs）现在被认为是所有晚期MSI-H/dMMR癌症患者治疗的基石。然而，在非结直肠肿瘤中，现有的证据不太有力，提出了重要的挑战，例如确定不同治疗线的最佳治疗方案和确定适当的治疗持续时间。最近，ICIs在局部疾病中的疗效也得到了证实，这引发了关于将其纳入治疗意图策略的新问题，例如，鉴于早期肿瘤预后良好，过度治疗的风险、非手术治疗的作用、最佳治疗方案和时间表。在这篇综述中，我们总结了支持早期和晚期MSI-H/dMMR非结直肠癌患者治疗策略的现有文献和证据。

Background

Gastric or gastroesophageal junction (GEJ) cancers are usually diagnosed at advanced stages with poor prognoses and 5-year survival rates. Standard-of-care first-line treatment of human epidermal growth factor receptor 2 (HER2)-positive locally advanced or metastatic disease is chemotherapy and trastuzumab, plus pembrolizumab for programmed death-ligand 1 (PD-L1)-positive [combined positive score (CPS) ≥1] tumors. Trastuzumab deruxtecan (T-DXd) 6.4 mg/kg monotherapy is approved as second-line treatment for patients with HER2-positive gastric or GEJ cancer. DESTINY-Gastric03 (NCT04379596) showed that first-line T-DXd 5.4 mg/kg plus chemotherapy with or without pembrolizumab in the advanced setting had manageable safety and promising efficacy in HER2-positive gastric or GEJ cancer.

Aim

To investigate a first-line T-DXd plus platinum-free chemotherapy with pembrolizumab treatment approach for patients with HER2-positive gastric or GEJ cancer.

Trial design

DESTINY-Gastric05 (NCT06731478) is a global, multicenter, open-label, randomized, phase III trial to evaluate the efficacy and safety of first-line T-DXd 5.4 mg/kg plus 5-fluorouracil or capecitabine and pembrolizumab versus platinum-based chemotherapy with trastuzumab and pembrolizumab in patients with unresectable, locally advanced or metastatic, centrally confirmed HER2-positive (immunohistochemistry 3+ or immunohistochemistry 2+/in situ hybridization positive) gastric or GEJ cancer with a PD-L1 CPS ≥1. An exploratory cohort is to evaluate T-DXd plus 5-fluorouracil or capecitabine in patients with PD-L1 CPS <1.

背景：胃或胃食管交界处（GEJ）癌通常在晚期诊断，预后差，5年生存率低。人类表皮生长因子受体2 （HER2）阳性的局部晚期或转移性疾病的标准护理一线治疗是化疗和曲妥珠单抗加派姆单抗治疗程序性死亡配体1 （PD-L1）阳性[联合阳性评分(CPS)≥1]的肿瘤。Trastuzumab deruxtecan (T-DXd) 6.4 mg/kg单药疗法被批准作为her2阳性胃癌或GEJ癌患者的二线治疗。DESTINY-Gastric03 （NCT04379596）显示，在晚期治疗中，一线T-DXd 5.4 mg/kg加化疗加或不加派姆单抗治疗her2阳性胃癌或GEJ癌具有可控的安全性和良好的疗效。目的探讨一线T-DXd +无铂化疗联合派姆单抗治疗her2阳性胃癌或GEJ癌的方法。宿命- gastric05 （NCT06731478）是一项全球性、多中心、开放标签、随机III期试验，旨在评估一线T-DXd 5.4 mg/kg加5-氟尿嘧啶或卡培他滨和派姆单抗与曲妥珠单抗和派姆单抗联合铂基化疗在不可切除、局部晚期或转移性、中心证实her2阳性（免疫组织化学3+或免疫组织化学2+/原位杂交阳性）胃癌或胃癌，PD-L1 CPS≥1。一项探索性队列研究旨在评估T-DXd联合5-氟尿嘧啶或卡培他滨对PD-L1 CPS患者的治疗效果。

Background

Human epidermal growth factor receptor 2 (HER-2) overexpression/amplification is a known prognostic and predictive biomarker in breast and gastric cancer. However, its role in metastatic colorectal cancer (mCRC) is still debated.

Patients and methods

We conducted an exploratory analysis to investigate the role of HER-2 amplifications/mutations in patients with RAS/BRAF^V600 wild type (WT), microsatellite stable (MSS) mCRC enrolled in the CAPRI-2 GOIM trial, who received FOLFIRI/cetuximab as first-line therapy. At baseline, plasma and tumor tissue samples were collected for comprehensive genomic profiling using the FoundationOne CDx assay. HER-2 positive tumors were defined in case of HER-2 mutations or gene amplification, defined by using a gene copy number cut-off of ≥4.

Results

Patients with HER-2 negative tumors had numerically higher objective response rates [78% versus 60%; odd-ratio, 1.95, 95% confidence interval (CI): 0.47-8; P = 0.4] compared with HER-2 positive tumors. Patients with HER-2 positive mCRC had worse median progression-free survival (PFS) [(7.54 months; 95% CI:4.99-Not evaluable (NE) versus 13.47 months (95% CI: 11.76-16.3); hazard ratio (HR): 2.47; 95% CI: 1.27-4.65; P = 0.007] as well as worse median overall survival [16.4 months (95% CI:9.4-NE) versus 33.4 (30.36-NE); HR: 2.54; 95% CI: 1.09-5.93; P = 0.031] compared with patients with HER-2 negative tumors. Of note, 6/7 cases with HER-2 mutations exhibited limited benefit from treatment with FOLFIRI plus cetuximab with PFS inferior to 8 months.

Conclusion

Taken together, these results highlight the need to test HER-2 gene alterations for patients with RAS/BRAF^V600 WT, MSS mCRC, who are candidates for anti-epidermal growth factor receptor therapies.

人表皮生长因子受体2 （HER-2）过表达/扩增是已知的乳腺癌和胃癌预后和预测性生物标志物。然而，其在转移性结直肠癌（mCRC）中的作用仍存在争议。患者和方法我们进行了一项探索性分析，研究HER-2扩增/突变在CAPRI-2 GOIM试验中纳入的RAS/BRAFV600野生型（WT）、微卫星稳定型（MSS） mCRC患者中的作用，这些患者接受FOLFIRI/西图昔单抗作为一线治疗。基线时，收集血浆和肿瘤组织样本，使用FoundationOne CDx检测进行全面的基因组分析。HER-2阳性肿瘤定义为HER-2突变或基因扩增，以基因拷贝数截止值≥4为标准。结果HER-2阴性肿瘤患者的客观有效率更高[78%比60%；奇比为1.95,95%置信区间（CI）： 0.47- 48；P = 0.4]与HER-2阳性肿瘤比较。HER-2阳性mCRC患者的中位无进展生存期（PFS）较差(7.54个月，95% CI:4.99-不可评估（NE）， 13.47个月（95% CI: 11.76-16.3）；风险比（HR）： 2.47；95% ci: 1.27-4.65；P = 0.007]以及更差的中位总生存期[16.4个月（95% CI:9.4-NE）对33.4个月（30.36-NE）；人力资源:2.54;95% ci: 1.09-5.93；P = 0.031]与HER-2阴性肿瘤患者相比。值得注意的是，6/7的HER-2突变患者使用FOLFIRI加西妥昔单抗治疗的获益有限，PFS低于8个月。综上所述，这些结果强调了在RAS/BRAFV600 WT、MSS mCRC患者中检测HER-2基因改变的必要性，这些患者是抗表皮生长因子受体治疗的候选者。

Biliary tract cancer and pancreatic cancer are aggressive malignancies, typically diagnosed in patients >50 years of age. Lately, <50 years of age has been rising, presenting unique challenges and clinical features that distinguish them from late-onset cases.

Here, we review the clinical, biological, and molecular characteristics of early-onset biliary tract cancer and pancreatic cancer and compare them with their late-onset counterparts. We also examine treatment patterns, efficacy, and the potential role of targeted therapies, as well as the potential psychological and social effects on younger patients, with particular emphasis on fertility. We therefore offer insights into the unique challenges and therapeutic strategies in managing early-onset disease.

胆道癌和胰腺癌是侵袭性恶性肿瘤，通常在50岁以上的患者中诊断出来。最近，50岁的患者人数不断上升，呈现出独特的挑战和临床特征，使其与晚发病例区分开来。在这里，我们回顾了早发性胆道癌和胰腺癌的临床、生物学和分子特征，并将它们与晚发性胆道癌进行了比较。我们还研究了治疗模式、疗效和靶向治疗的潜在作用，以及对年轻患者的潜在心理和社会影响，特别强调生育能力。因此，我们提供了独特的挑战和治疗策略，在管理早发性疾病的见解。

Background

First-line treatment strategies for (very) early-stage hepatocellular carcinoma (HCC) include liver transplantation, surgical resection and thermal ablation. Stereotactic body radiotherapy (SBRT) has recently been included in the European Association for the Study of the Liver Clinical Practice Guidelines on the management of hepatocellular carcinoma as an alternative ablative strategy. We aimed to carry out a systematic review and meta-analysis on oncological outcomes and toxicity of SBRT focused on early-stage HCC treatment.

Materials and methods

We carried out a systematic literature search in PubMed, Embase, and the Cochrane Library from inception throughout October 2022. Studies of SBRT targeting treatment-naive (very) early-stage HCC (BCLC 0/A) patients were included.

Results

One prospective and 15 retrospective studies were included in this review. In aggregate, SBRT in 1249 patients resulted in a 1-, 2-, and 3-year local control rate of 94% (95% CI 92%-97%), 89% (95% CI 85%-93%), and 79% (95% CI 68%-90%), respectively. The pooled results of the 1-, 2-, and 3-year overall survival rate were 90% (95% CI 85%-94%), 75% (95% CI 63%-87%), and 59% (95% CI 45%-73%), respectively. Grade ≥3 toxicity was observed in 2% of patients (95% CI 0%-4%).

Conclusion

This systematic review and meta-analysis showed that SBRT is an effective and safe treatment modality for treatment-naive patients with early-stage HCC. The data support incorporation of SBRT as a treatment option in the treatment algorithms for (very) early-stage HCC.

背景：（极）早期肝细胞癌（HCC）的一线治疗策略包括肝移植、手术切除和热消融。立体定向放射治疗（SBRT）最近被纳入欧洲肝脏临床实践研究协会关于肝细胞癌管理的指导方针，作为一种替代消融策略。我们的目的是对早期HCC治疗的SBRT的肿瘤预后和毒性进行系统回顾和荟萃分析。材料和方法从2022年10月开始，我们在PubMed、Embase和Cochrane图书馆进行了系统的文献检索。纳入了针对未接受治疗（极）早期HCC （BCLC 0/A）患者的SBRT研究。结果本综述纳入1项前瞻性研究和15项回顾性研究。总的来说，1249例SBRT患者的1年、2年和3年局部控制率分别为94% （95% CI 92%-97%）、89% （95% CI 85%-93%）和79% （95% CI 68%-90%）。1年、2年和3年总生存率的汇总结果分别为90% （95% CI 85%-94%）、75% （95% CI 63%-87%）和59% （95% CI 45%-73%）。在2%的患者中观察到≥3级毒性（95% CI 0%-4%）。结论本系统综述和荟萃分析显示，SBRT是一种有效且安全的治疗方式，适用于未接受治疗的早期HCC患者。数据支持将SBRT作为一种治疗方案纳入（非常）早期HCC的治疗算法。
