Abstract
A 69-year-old man was treated with lenvatinib after three sessions of proton beam therapy (PBT) for hepatocellular carcinoma. Five months after administration of lenvatinib, a dermatitis with huge skin ulcer formed in the site of PBT irradiation. Lenvatinib was immediately withdrawn, but the skin ulcer continued growing until about 2 weeks later. With topical and antibiotic treatment, the skin ulcer resolved after about 4 months. After administration of lenvatinib, potential skin damage due to PBT at the irradiated site may have become apparent. This is the first report describing skin ulcer by the combination of lenvatinib administration and PBT.

Proton Beam Therapy and Photon-Based Magnetic Resonance Image-Guided Radiation Therapy: The Next Frontiers of Radiation Therapy for Hepatocellular Carcinoma. Technol Cancer Res Treat 2023; 22:15330338231206335. [PMID: 37908130 PMCID: PMC10621304 DOI: 10.1177/15330338231206335] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Revised: 08/21/2023] [Accepted: 09/21/2023] [Indexed: 11/02/2023] Open
Abstract
External beam radiation therapy (EBRT) has increasingly been utilized in the treatment of hepatocellular carcinoma (HCC) due to technological advances with positive clinical outcomes. Innovations in EBRT include improved image guidance, motion management, treatment planning, and highly conformal techniques such as intensity-modulated radiation therapy (IMRT) and stereotactic body radiation therapy (SBRT). Moreover, proton beam therapy (PBT) and magnetic resonance image-guided radiation therapy (MRgRT) have expanded the capabilities of EBRT. PBT offers the advantage of minimizing low- and moderate-dose radiation to the surrounding normal tissue, thereby preserving uninvolved liver and allowing for dose escalation. MRgRT provides the advantage of improved soft tissue delineation compared to computerized tomography (CT) guidance. Additionally, MRgRT with online adaptive therapy is particularly useful for addressing motion not otherwise managed and reducing high-dose radiation to the normal tissue such as the stomach and bowel. PBT and online adaptive MRgRT are emerging technological advancements in EBRT that may provide a significant clinical benefit for patients with HCC.

Abstract
Proton radiation therapy plays a central role in the treatment of hepatocellular carcinoma (HCC). Because of the near-zero exit dose and improved sparing of normal liver parenchyma, protons are being used even in challenging scenarios, including larger or multifocal liver tumors, and those associated with vascular tumor thrombus. There is a mounting level of evidence that suggests that protons are superior to photons in terms of survival and toxicity outcomes, specifically the progression to liver failure. A randomized controlled trial comparing protons to photons is currently underway to verify this hypothesis.

Abstract
PURPOSE There are many treatment choices for hepatocellular carcinoma (HCC), one of which is proton beam therapy (PBT). The purpose of this study was to compare surgical resection (SR) and PBT to clarify the prognostic factors for operable HCC based on a single institution's database. METHODS Patients with single primary nodular HCC ≤ 100 mm without vessel invasion on pretreatment imaging were divided into the SR group and PBT group. In the PBT group, the patients with unresectable HCC due to their liver function and/or performance status were excluded. RESULTS There were 314 and 31 patients who underwent SR and PBT, respectively. The median survival time in the SR group was significantly better than in the PBT group (104.1 vs. 64.6 months, p = 0.008). Regarding the relapse-free survival (RFS), there was no significant difference between the SR and PBT groups (33.8 vs. 14.0 months, p = 0.099). CONCLUSION The RFS was comparable between the PBT and SR groups. However, the PBT group had a significantly worse overall survival than the SR group. SR may therefore be favorable as an initial treatment for HCC compared to PBT.

Abstract
BACKGROUND Therapeutic evaluation of 3-dimensional conformal radiotherapy (3DCRT) is rarely reported for non-resectable hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT). The aim of this study was to determine the value of contrast-enhanced ultrasound (CEUS) in evaluating the therapeutic response of HCC with PVTT treated with 3DCRT. MATERIAL AND METHODS PVTT reduction rate in the study was determined after 3DCRT using time intensity curve (TIC) analysis software before and after radiotherapy. Seventy-nine HCC patients with PVTT treated with 3DCRT were studied. HCC and PVTT were performed by CEUS, before and after 3DCRT, over time. The parameters of blood flow, including arrival time (AT), time to peak (TTP), peak intensity (PI), washout time (WT), and area under the curve (AUC), were quantified and evaluated on still images by CEUS. RESULTS After 3DCRT, typing and staging of PVTT in 38 patients was decreased, the reduction rate was 48.1%. HCC was effective in 45 patients, the effective rate was 57%; No differences were found between the PVTT reduction rate and the HCC effective rate (χ2=2.96, P>0.05). In the effective group, the PI and AUC of HCCs and PVTTs after 3DCRT were significantly lower than before 3DCRT, while the other parameters of TIC were not significantly different before and after 3DCRT. CONCLUSIONS CEUS might be a useful monitoring option for the evaluation of HCC with PVTT treated with 3DCRT. CEUS might be useful as an important choice for monitoring and evaluation HCC with PVTT after 3DCRT. TIC parameters might provide quantitative data for efficacy evaluation, which helps to modify treatment strategies timely and accurately.

Abstract
Despite the conformality of modern X-ray therapy limiting high dose received by normal tissues the physical properties of X-rays make it impossible to avoid dose being delivered distal to the target. This "exit dose" is likely clinically significant especially for patients with gastrointestinal (GI) cancers when considering that even low dose received by the heart, lungs, bowel, and other radiosensitive structures can lead to morbidity and even may affect long-term tumor control. In contrast, proton beam therapy (PBT) delivers no "exit dose" and a growing body of literature suggests that this may improve clinical outcomes by reducing toxicity and even allowing for safe dose intensification to enhance tumor control. While there are not yet robust prospective data demonstrating the role of PBT for GI cancers, emerging retrospective data provide a strong rationale for continued study of how PBT may improve the therapeutic ratio for these patients. Here we review these data as well as discuss ongoing clinical trials of PBT for GI cancers.

Particle radiotherapy, a novel external radiation therapy, versus liver resection for hepatocellular carcinoma accompanied with inferior vena cava tumor thrombus: A matched-pair analysis. Surgery 2017; 162:1241-1249.

Abstract
BACKGROUND Hepatocellular carcinoma accompanied with inferior vena cava tumor thrombus carries a dismal prognosis, and the feasibility of local treatment has remained controversial. The present study aimed to compare the outcomes of particle radiotherapy and liver resection in patients with hepatocellular carcinoma with inferior vena cava tumor thrombus. METHODS Thirty-one and 19 patients, respectively, underwent particle radiotherapy and liver resection for hepatocellular carcinoma with inferior vena cava tumor thrombus. A matched-pair analysis was undertaken to compare the short- and long-term outcomes according to tumor stage determined using the tumor-node-metastasis classification. RESULTS Both stages IIIB and IV (IVA and IVB) patients were well-matched for 12 factors, including treatment policy and patient and tumor characteristics. The median survival time of matched patients with stage IIIB tumors in the particle radiotherapy group was greater than that in the liver resection group (748 vs 272 days, P = .029), whereas no significant difference was observed in the median survival times of patients with stage IV tumors (239 vs 311 days, respectively). There were significantly fewer treatment-related complications of grade 3 or greater in the particle radiotherapy group (0%) than in the liver resection group (26%). CONCLUSION Particle radiotherapy is potentially preferable in hepatocellular carcinoma patients with stage IIIB inferior vena cava tumor thrombus and at least equal in efficiency to liver resection in those with stage IV disease, while causing significantly fewer complications. Considering the relatively high survival and low invasiveness of particle radiotherapy when compared to liver resection, this approach may represent a novel treatment modality for hepatocellular carcinoma with inferior vena cava tumor thrombus.

Abstract
Charged particle therapy (proton beam therapy and carbon ion therapy) is a form of radiotherapy which has the unique characteristic of superior depth dose distribution, and has been used for the treatment of hepatocellular carcinoma (HCC) in a limited number of patients, especially in Japan. We undertook a systematic review to define the clinical utility of charged particle therapy for patients with HCC. We searched the MEDLINE database from 1983 to June 2016 to identify clinical studies on charged particle therapy for HCC. Primary outcomes of interest were local control, overall survival, and late radiation morbidities. A total of 13 cohorts from 11 papers were selected from an initial dataset of 78 papers. They included a randomized controlled trial comparing proton beam therapy with transarterial chemoembolization, 9 phase I or II trials and 2 retrospective studies. The reported actuarial local control rates ranged from 71.4-95% at 3 years, and the overall survival rates ranged from 25-42.3% at 5 years. Late severe radiation morbidities were uncommon, and a total of 18 patients with grade ≥3 late adverse events were reported among the 787 patients included in this analysis. Charged particle therapy for HCC was associated with good local control with limited probability of severe morbidities. The cost-effectiveness and the distinctive clinical advantages of charged particle therapies should be clarified in order to become a socially accepted treatment modality for HCC.

Abstract
Long-term efficacy of proton beam therapy (PBT) remains unclear for patients with previously untreated hepatocellular carcinoma (HCC). We aimed to study the long-term outcomes of PBT according to Barcelona Clinic Liver Cancer (BCLC) staging classifications in patients with previously untreated HCC. The major eligibility criteria of this observational study were an Eastern Cooperative Oncology Group performance status (PS) 0-2, Child-Pugh grade A or B, previously untreated HCC covered within an irradiation field, and no massive ascites. A total of 66.0-77.0 GyE was administered in 10-35 fractions. Local tumor control (LTC), defined as no progression in the irradiated field, progression-free survival (PFS), and overall survival (OS) were assessed according to BCLC staging. From 2002 to 2009 at our institution, 129 patients were eligible. The 5-year LTC, PFS, and OS rates were 94%, 28%, and 69% for patients with 0/A stage disease (n = 9/21), 87%, 23%, and 66% for patients with B stage disease (n = 34), and 75%, 9%, and 25% for patients with C stage disease (n = 65), respectively. The 5-year LTC and OS rates of 15 patients with tumor thrombi in major vessels were 90% and 34%, respectively. Multivariate analyses revealed that PS (0 versus 1-2) was a significant prognostic factor for OS. No grade 3 or higher adverse effects were observed. PBT showed favorable long-term efficacies with mild adverse effects in BCLC stage 0 to C, and can be an alternative treatment for localized HCC especially when accompanied with tumor thrombi. This study was registered with UMIN Clinical Trials Registry (UMIN000025342).

Abstract
AIM To investigate the factors that influence survival of hepatocellular carcinoma (HCC) patients with portal vein tumor thrombosis (PVTT) following transarterial chemoembolization (TACE). METHODS Retrospectively enrolled HCC patients with PVTT (n = 57). Patients received TACE, and the local tumor response was evaluated by modified response evaluation criteria in solid tumor (mRECIST). Overall survival and disease progression were evaluated using Kaplan-Meier survival curves. Prognostic factors were determined by multivariate Cox regression analysis. RESULTS Following TACE, the median survival times was 8.3 months in HCC patients with PVTT. The median survival time was 3.1 months for patients with progressive disease following TACE and was 11.3 months for patients with complete response or partial response. The one-year rate of survival for patients with progressive disease was 5.0% and was lower than in patients with complete response or partial response (20.0%, P < 0.001). Multivariate analysis indicated that the presence of ascites, arteriovenous fistula and TACE response were significant factors for prognosis. The presence of early (<2 weeks) or late (≥2 weeks) PVTT was not a prognostic factor. CONCLUSION Our study indicates that TACE is feasible and potentially efficacious in HCC patients with PVTT, and identifies factors that may predict the prognosis of these patients.

Abstract
Hepatocellular carcinoma (HCC) is the second most common cause of cancer-related death worldwide. Many treatment modalities were developed for HCC, including surgical resection, percutaneous ethanol injection, radiofrequency ablation, transarterial chemoembolization, liver transplantation, and sorafenib therapy. Our institution has shown that proton beam therapy (PBT) is also a safe, effective, and feasible treatment modality for HCC. The University of Tsukuba began to use PBT for HCC in 1983, and we have reported many findings during the past 3 decades. In this review, we will describe the history of PBT, our experience of using PBT for HCC, and its application based on tumor location, thrombosis, tumor size, and liver function.

Hepatic resection of hepatocellular carcinoma after proton beam therapy: A case report. Hepatol Res 2016; 46:483-8.

Abstract
Despite the widespread use of proton beam therapy (PBT) as locoregional therapy, there is currently a lack of histological evidence about the therapeutic effect of PBT for hepatocellular carcinoma (HCC). We present a case of hepatectomy and histological examination of HCC initially treated by PBT. A 76-year-old man with chronic hepatitis C underwent routine ultrasound surveillance, which revealed a 22-mm HCC in segment 4 of the liver. His hepatic reserve was adequate for surgical resection of the tumor; however, he chose to undergo PBT because of his cardiac disease. The patient received 66 Gy in 10 fractions with no toxicity exceeding grade 1. Six months after completion of PBT, contrast computed tomography showed that the tumor had increased in size to 27 mm, and the marginal part of the tumor, but not the central region, was enhanced. Additionally, two new hypervascular nodules were present in segments 5 and 6. The patient underwent surgical treatment 7 months after PBT. The operation and postoperative clinical course were uneventful. Nine months later, however, computed tomography demonstrated new, small, enhanced nodules in the remnant liver (segments 3, 5 and 6) and sacrum. In conclusion, PBT is a valuable treatment for HCC; however, it is difficult to evaluate therapeutic effect of HCC during the early post-irradiation period and provide an alternative treatment if PBT is not effective, especially in HCC cases with good liver function.

Abstract
AIM Proton beam therapy is safe and more effective than conventional radiation therapy for the local control of nodular hepatocellular carcinoma (HCC). However, evaluating therapeutic response by imaging is not accurate during the early post-irradiation period. Therefore, we examined whether the histopathological study of biopsy specimens obtained at 3 weeks after irradiation can be used to more accurately assess therapeutic response. METHODS Fifteen HCC lesions from 13 patients were treated with proton beam irradiation. Tissue biopsy samples were obtained using abdominal ultrasound-guided percutaneous fine-needle aspiration from the center of the tumor before, 3 weeks after and 1 year post-proton therapy. The specimens were examined after staining with hematoxylin-eosin (HE) and a MIB-1 antibody. RESULTS MIB-1 labeling indices (LI) before treatment were 13.0 ± 8.5% (mean ± SD; range, 0.6-27.0), whereas those 3 weeks after proton therapy were significantly reduced to 3.2 ± 2.4% (range, 0.6-8.9) (P < 0.05). Although the tumor size was reduced, we did not observe a reduction in tumor blood flow by dynamic computed tomography or degenerative changes by HE. All lesions that displayed reduced MIB-1 LI at 3 weeks post-proton treatment were ultimately diagnosed as complete response at 1 year after treatment. In contrast, one case with increased MIB-1 LI at 3 weeks had significant tumor size progression at 1 year post-treatment. CONCLUSION The percutaneous fine-needle aspiration biopsy of HCC is a safe and useful tool that can be used to evaluate the response to proton irradiation. In particular, MIB-1 LI may provide additional information to assess the therapeutic response of HCC during the early post-irradiated period.

Abstract
Background Proton-beam radiotherapy (PBT) has been shown to be effective to hepatocellular carcinoma (HCC) as a nonsurgical local treatment option. However, HCC still remains as one of the most difficult cancers to be cured because of frequent recurrences. Thus, methods to inhibit the recurrence need to be explored. To prevent the HCC recurrence, we here report on a prospective phase I study of ‘in situ’ tumor vaccination using CalTUMP, a newly developed immunoadjuvant consisting of BCG extract bound to hydroxyapatite and microparticulated tuberculin, following local PBT for HCC. Methods Patients with locally advanced recurrent HCC, which had been heavily pretreated with various treatments, were enrolled. PBT was performed with the conventional method to the target HCC. Subsequently, CalTUMP was injected into the same irradiated-tumor three times at one-week intervals. Three dose-levels of CalTUMP (1/10, 1/3, and 1/1) were administered to 3 patients each. Vital signs, blood samples, ultrasound, and computed tomographic scans were monitored to evaluate the safety. Results Three intratumoral injections of CalTUMP following PBT (median dose: 72.6 GyE) were accomplished in 9 patients. Transient low-grade fever and minor laboratory changes were observed in 7 patients after CalTUMP injections. No other treatment-related adverse events were observed. Median progression-free survival was 6.0 months (range: 2.1-14.2) and 4 patients were progression-free for more than 1 year. Conclusions Intratumoral injection of CalTUMP following PBT was feasible and safe in patients with heavily pre-treated HCC. Further clinical studies to evaluate the efficacy of this in situ tumor vaccination are warranted.

Abstract
UNLABELLED Cholangiocarcinoma (CC) is an aggressive malignant tumor for which useful markers are not presently available for early and precise diagnosis. The aim of this study was therefore to identify a high-performance diagnostic marker with a special focus on glyco-alteration of glycoproteins. In the course of study, we found that Wisteria floribunda agglutinin (WFA) is the best probe to differentiate intrahepatic cholangiocarcinoma (ICC) lesions from normal bile duct epithelia (BDE) (P < 0.0001). The subsequent histochemical study confirmed ICC-specific WFA staining on 165 tissue specimens. On the other hand, the WFA staining was shown to be closely associated with that of MY.1E12 established previously against sialylated mucin 1 (MUC1) by double-staining experiments. Moreover, glyco-alteration of MUC1 could be verified by western blotting of WFA-captured bile samples from patients with CC patients. Thus, we attempted to construct an enzyme-linked immunosorbent assay system for more convenient CC diagnosis, where WFA-coated plates, the specific monoclonal antibody MY.1E12, and the bile specimens from CC including ICC (n = 30) and benign diseases (n = 38) were combined. As a result, CC was clearly distinguished from benign diseases with statistical scores (sensitivity = 90.0%, specificity = 76.3%, and area under the curve = 0.85). As a particular note, the obtained sensitivity is the highest score among those having been so far reported. CONCLUSION Our approach focusing significant glyco-alteration of a particular glycoprotein yielded a novel diagnostic system for CC with satisfactory clinical scores.

Abstract
BACKGROUND AND PURPOSE To compare the efficacy and toxicity of short-course carbon ion radiotherapy (C-ion RT) for patients with hepatocellular carcinoma (HCC) in terms of tumor location: adjacent to the porta hepatis or not. MATERIALS AND METHODS The study consisted of 64 patients undergoing C-ion RT of 52.8 GyE in four fractions between April 2000 and March 2003. Of these patients, 18 had HCC located within 2 cm of the main portal vein (porta hepatis group) and 46 patients had HCC far from the porta hepatis (non-porta hepatis group). We compared local control, survival, and adverse events between the two groups. RESULTS The 5-year overall survival and local control rates were 22.2% and 87.8% in the porta hepatis group and 34.8% and 95.7% in the non-porta hepatis group, respectively. There were no significant differences (P=0.252, P=0.306, respectively). Further, there were no significant differences in toxicities. Biliary stricture associated with C-ion RT did not occur. CONCLUSIONS Excellent local control was obtained independent of tumor location. The short-course C-ion RT of 52.8 GyE in four fractions appears to be an effective and safe treatment modality in the porta hepatis group just as in the non-porta hepatis group.

Abstract
BACKGROUND AND PURPOSE To examine whether liver volume changes affect prognosis and hepatic function in patients treated with carbon ion radiotherapy (CIRT) for hepatocellular carcinoma (HCC). MATERIAL AND METHODS Between April 1995 and March 2003, among the cases treated with CIRT, 43 patients with HCC limited to the right hepatic lobe were considered eligible for the study. The left lateral segment was defined as the non-irradiated region. Liver volume was measured using contrast CT at 0, 3, 6, and 12 months after CIRT. We examined serum albumin, prothrombin activity, and total bilirubin level as hepatic functional reserve. RESULTS After CIRT, the non-irradiated region showed significant enlargement, and enlarged volume of this region 3 months after CIRT 50 cm(3) was a prognostic factor. The 5-year overall survival rates were 48.9% in the larger enlargement group (enlarged volume of non-irradiated region 3 months after CIRT > or =50 cm(3)) and 29.4% in the smaller enlargement group (as above, <50 cm(3)). The larger enlargement group showed better hepatic functional reserve than the smaller enlargement group 12 months after CIRT. CONCLUSIONS This study suggests that compensatory enlargement in the non-irradiated liver after CIRT contributes to the improvement of prognosis.

Abstract
We report a 48-year-old man with hepatocellular carcinoma (HCC) treated with hepatic arterial infusion (HAI) chemotherapy followed by proton beam therapy. The HCC lesion in this patient was 88 mm in diameter, with portal vein tumor thrombosis in the right lobe of the liver. He was first treated with 5-fluorouracil, cisplatin, and isovorin, administered by HAI, combined with interferon-alpha, and he was subsequently treated with epirubicin and mitomycin-C administered by HAI. However, no definite efficacy of either of these treatments was observed. Then, after 3 weeks' continuous administration of irinotecan by HAI, the tumor size decreased to 68 mm in diameter. However, 3 months after reduction of the tumor, the tumor had become enlarged to 100 mm in diameter and intrahepatic metastases were prominent. Angiographic findings indicated that the HCC was fed not only from the right hepatic artery but also from the left gastric and right and left subphrenic arteries. After rearrangement of the arteries, and 3 months' continuous HAI chemotherapy with irinotecan, plus hyperthermia, the tumor size had decreased to 50 mm in diameter. The reduction rate of the main tumor according to the Response Evaluation Criteria in Solid Tumors was 43%; therefore, the efficacy of this treatment was judged as a partial response. Two months after reduction of the tumor, the patient's serum alpha-fetoprotein (AFP) level was elevated, and so docetaxel was administered by HAI instead of irinotecan. The liver tumors showed gradual enlargement during the administration of docetaxel, although the AFP level was suppressed. Proton beam therapy was instituted and the liver tumors showed necrosis after this therapy. The patient died of hepatic failure and distant metastases 6 years after the onset of HCC. As far as we know, this is the first case report of HCC treated effectively with irinotecan administered by HAI followed by proton beam therapy in which tumor suppression and the long-term survival of the patient were observed.

Abstract
A group of Swedish oncologists and hospital physicists have estimated the number of patients in Sweden suitable for proton beam therapy. The estimations have been based on current statistics of tumour incidence, number of patients potentially eligible for radiation treatment, scientific support from clinical trials and model dose planning studies and knowledge of the dose-response relations of different tumours and normal tissues. In gastrointestinal cancers, it is assessed that at least 345 patients, mainly non-resectable rectal cancers, oesophageal and liver cancers, are eligible. Great uncertainties do however exist both in the number of patients with gastrointestinal cancers suitable for radiation therapy, and in the proportion of those where proton beams may give sufficiently better results.

Abstract
Background and Purpose: Hepatocellular carcinoma (HCC) patients with severe cirrhosis are usually treated with supportive care because of their poor prognosis. However, the survival of severe cirrhotic patients has recently improved due to advanced treatments. The aim of this study was to define the role of proton beam therapy for HCC patients with severe cirrhosis. Patients and Methods: 19 HCC patients with Child-Pugh class C cirrhosis received proton beam therapy. The hepatic tumors were solitary in 14 patients and multiple in five, and the tumor size was 25–80 mm (median 40 mm) in maximum diameter. No patient had regional lymph node or distant metastasis. Total doses of 50–84 Gy (median 72 Gy) in ten to 24 fractions (median 16) were delivered to the tumors. Results: Of the 19 patients, six, eight and four died of cancer, liver failure and intercurrent diseases, respectively, during the follow-up period of 3–63 months (median 17 months) after treatment. A remaining patient was alive with no evidence of disease 33 months after treatment. All but one of irradiated tumors were controlled during the follow-up period. Ten patients had new intrahepatic tumors outside the irradiated volume. The overall and progression-free survival rates were 53% and 47% at 1 year, respectively, and 42% each at 2 years. Performance status and Child-Pugh score were significant prognostic factors for survival. Therapy-related toxicity of grade 3 or more was not observed. Conclusion: Proton beam therapy for HCC patients with severe cirrhosis was tolerable. It may improve survival for patients with relatively good general condition and liver function.

Abstract
Three patients with hepatocellular carcinoma (HCC) and inferior vena cava tumor thrombus (IVCTT) were treated using proton beam therapy at the University of Tsukuba, Japan. A total dose of 50-70 Gy in 10-35 fractions was given to the primary tumor and IVCTT. All the patients survived for more than 1 year from the beginning of proton beam therapy (13-55 months) and no treatment-related toxicity of grade 3 or higher was observed. These cases suggest that proton beam therapy is safe and effective for patients with HCC associated with IVCTT.

Abstract
The prognosis of patients with hepatocellular carcinoma (HCC) accompanied by portal vein tumor thrombus (PVTT) is generally poor if left untreated: a median survival time of 2.7-4.0 mo has been reported. Furthermore, while transcatheter arterial chemoembolization (TACE) has been shown to be safe in selected patients, the median survival time with this treatment is still only 3.8-9.5 mo. Systemic single-agent chemotherapy for HCC with PVTT has failed to improve the prognosis, and the response rates have been less than 20%. While regional chemotherapy with low-dose cisplatin and 5-fluorouracil or interferon and 5-fluorouracil via hepatic arterial infusion has increased the response rate, the median survival time has not exceeded 12 (range 4.5-11.8) mo. Combined treatment consisting of radiation for PVTT and TACE for liver tumor has achieved a high response rate, but the median survival rates have still been only 3.8-10.7 mo. With hepatic resection as monotherapy, the 5-year survival rate and median survival time were reportedly 4%-28.5% and 6-14 mo. The most promising results were reported for combined treatments consisting of hepatectomy and TACE, chemotherapy, or internal radiation. The reported 5-year survival rates and median survival times were 42% and 31 mo for TACE followed by hepatectomy; 36.3% and 22.1 mo for hepatectomy followed by hepatic arterial infusion chemotherapy; and 56% for chemotherapy or internal radiation followed by hepatectomy.

Abstract
BACKGROUND The authors conducted a retrospective review to define the usefulness of proton beam therapy for patients who had hepatocellular carcinoma (HCC) with limited treatment options. METHODS Twenty-one patients with HCC for whom other treatment modalities either were contraindicative or were unfeasible because of coexisting diseases and unfavorable conditions received proton beam therapy. Four patients had renal failure, 2 patients had severe heart disease, 9 patients had severe cirrhosis, 1 patient had aplastic anemia, 1 patient had a dissecting abdominal aortic aneurysm before treatment, and 4 patients had bleeding tendency or unresectable tumors. Moreover, 2 of the latter 4 patients were allergic to iodine, and 2 other patients were unable to be catheterized for transcatheter arterial chemoembolization. Hepatic tumors were solitary in 14 patients and multiple in 7 patients, and the tumors ranged in greatest dimension from 25 mm to 100 mm (median, 40 mm). No patient had regional lymph node or distant metastasis. Total doses of 63 grays (Gy) to 84 Gy (median, 73 Gy) in 13 to 27 fractions (median, 18 fractions) were used for tumor treatments. RESULTS All but 1 of the irradiated tumors were controlled at a median follow-up of 3.3 years. The objective response rate was 81%, and the primary site-control rate was 93% at 5 years. Eleven patients had intrahepatic recurrences, and 2 patients had distant metastases in the lungs. Four of 11 patients with intrahepatic recurrences received a second course of proton beam therapy, and all recurrent tumors were controlled. The overall and cause-specific survival rates were 62% and 82% at 2 years, respectively, and 33% and 67% at 5 years, respectively. Grade > or =3 therapy-related toxicities were not observed. CONCLUSIONS Proton beam therapy was safe and effective for a variety of patients with HCC. The current results suggested that this method was tolerable and effective, even for patients with HCC who had limited treatment options.

Abstract
Diseases of companion animals are shifting from infectious diseases to neoplasms (cancer), and since radiation therapy is one of the effective choices available for cancer treatment, the application of radiotherapy in veterinary medicine is likely to increase. However tumor tissues have different radiosensitivities, and therefore it is important to determine the intrinsic radiosensitivity of tumors in individual patients in advance of radiotherapy. We have studied the relationship between the surviving cell fraction measured by a clonogenic assay and DNA double strand breaks detected by a comet assay under neutral conditions in three canine tumor cell lines, after gamma-ray and carbon ion irradiation. In all the cell lines, cell death assessed by the clonogenic assay was much higher following irradiation with carbon ions than with gamma-rays. The initial and residual (4 hr) DNA damage due to gamma-ray and carbon ion irradiation were higher in a radiosensitive cell line than in a radioresistant cell line. The surviving cell fraction at 2 Gy (SF2) showed a tendency for correlation with both the initial and residual DNA damage. In particular, the residual damage per Gy was significantly correlated with SF2, regardless of the type of radiation. This indicates that cellular radiosensitivity can be predicted by detection of radiation-induced residual DNA damage.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common tumors globally, with varying prevalence based on endemic risk factors. In high-risk populations, including those with hepatitis B or C or with cirrhosis, serum alpha-fetoprotein (AFP) and screening ultrasound have improved detection of resectable HCC. Treatment options, including surgical resection, for patients with HCC must be selected based on the number and size of hepatic tumors, underlying hepatic function, patient condition, and available resources. An approach, which has been summarized shows the corresponding treatment choices under given clinical circumstances. For cirrhotic patients with less than three tumor nodules of a size less than 3 cm or a solitary HCC less than 5 cm, liver transplantation offers long-term survival similar to that observed in patients transplanted for nonmalignant disease. Ablative treatment using either chemical or thermal techniques provides locally effective tumor destruction. Transcatheter arterial chemoembolization (TACE) is commonly used for palliation of unresectable tumors as well as an adjunct to surgical resection, treatment of tumors before transplant, and in conjunction with other ablative therapies in a multimodality approach. Regional approaches to chemotherapy have produced more encouraging results than systemic chemotherapy, although both remain ineffective for long-term tumor control. Several newer treatment modalities are under investigation, including gene therapy, tagged antibodies, isolated perfusion, and novel radiotherapy techniques.

Abstract
AIM To clarify the efficacy and safety of three-dimensional conformal radiotherapy (3-D CRT) for this disease and to specify patient subgroups suitable for this treatment. METHODS Fifty-two patients with HCC received PVI-targeted radiation therapy from January 1995 through December 2003. Portal venous invasion (PVI) was found in the second or lower order branches of the portal vein in 6 patients, in the first branch in 24 patients and in the main trunk in 22 patients. Child classifications of liver function before radiation therapy were A, B, and C for 19, 24 and 2 patients, respectively. All patients received three-dimensional conformal radiotherapy with a total dose ranging from 39 to 60 Gy (57.0 Gy in average). RESULTS Overall survival rates at 1, 2, 3, 4, and 5 years were 45.1%, 25.3%, 15.2%, 10.1%, and 5.1%, respectively. Univariate analysis revealed that Child status, the number of tumor foci, tumor type, transcatheter arterial embolization (TAE) after radiation therapy were statistically significant prognostic factors. Multivariate analysis showed that the number of tumor foci and TAE after radiation therapy were statistically significant. CONCLUSION The results of this study strongly suggest the efficacy of 3-D CRT as treatment for PVI in HCC. 3-D CRT is recommended in combination with post-radiation TAE for PVI of HCC with 5 tumor foci or less in the liver and with Child A liver function.

Abstract
BACKGROUND Treatment modalities for patients with hepatocellular carcinoma (HCC) who have portal vein tumor thrombus (PVTT) are limited and controversial; furthermore, the prognosis for these patients is extremely poor. The authors conducted a retrospective review to determine the role of proton beam therapy in the treatment of patients who had HCC with PVTT. METHODS Twelve patients with HCC who had tumor thrombus in the main trunk or major branches of the portal vein (clinical T3-T4N0M0) were treated with proton beam therapy. At the time they received proton beam irradiation, patients ranged in age from 42 years to 80 years (median, 62 years), and their tumors ranged in size from 40 mm to 110 mm (median, 60 mm) in greatest dimension. A total dose of 50-72 gray (Gy) (median, 55 Gy) in 10-22 fractions was delivered to the tumors, including PVTT. RESULTS All tumors that were treated with proton beam therapy remained controlled at a median follow-up of 2.3 years (range, 0.3-7.3 years). Among 12 patients, 10 patients had new liver tumors outside the irradiated volume 0.1-2.4 years after proton beam therapy, and 3 patients also had distant metastases; consequently, 8 patients died of disease, and 2 patients were salvaged by further therapies. The remaining two patients were alive with no evidence of disease 4.3 years and 6.4 years after proton beam therapy. The progression-free survival rates were 67% at 2 years and 24% at 5 years. The median progression-free survival was 2.3 years. According to the Acute Radiation Morbidity Scoring Criteria (Radiation Therapy Oncology Group), therapy-related toxicity > or = Grade 3 was not observed. CONCLUSIONS Proton beam therapy for patients with HCC who had PVTT was feasible and effective. It appeared to improve survival and local control significantly for these patients.

Abstract
PURPOSE We present results of patients with hepatocellular carcinoma (HCC) treated with proton beam therapy. EXPERIMENTAL DESIGN We reviewed 162 patients having 192 HCCs treated from November 1985 to July 1998 by proton beam therapy with or without transarterial embolization and percutaneous ethanol injection. The patients in the present series were considered unsuitable for surgery for various reasons, including hepatic dysfunction, multiple tumors, recurrence after surgical resection, and concomitant illnesses. The median total dose of proton irradiation was 72 Gy in 16 fractions over 29 days. RESULTS The overall survival rate for all of the 162 patients was 23.5% at 5 years. The local control rate at 5 years was 86.9% for all 192 tumors among the 162 patients. The degree of impairment of hepatic functions attributable to coexisting liver cirrhosis and the number of tumors in the liver significantly affected patient survival. For 50 patients having least impaired hepatic functions and a solitary tumor, the survival rate at 5 years was 53.5%. The patients had very few acute reactions to treatments and a few late sequelae during and after the treatments. CONCLUSIONS Proton beam therapy for patients with HCC is effective, safe, well tolerable, and repeatable. It is the useful treatment mode for either cure or palliation for patients with HCC irrespective of tumor size, tumor location in the liver, insufficient feeding of the tumor with arteries, presence of vascular invasion, impaired hepatic functions, and coexisting intercurrent diseases.

Abstract
PURPOSE To present the results of proton beam therapy for patients with esophageal cancer. METHODS AND MATERIALS This study reviewed 46 patients with esophageal cancer who were treated between 1985 and 1998 using proton beams with or without X-rays. All patients had locoregionally confined disease; all but one had squamous cell carcinoma. Of the 46 patients, 40 received combinations of X-rays (median, 48 Gy) and protons (median, 31.7 Gy) as a boost. The median total dose of combined X-ray and proton radiation for the 40 patients was 76.0 Gy (range, 69.1-87.4 Gy). The remaining 6 patients received only proton beam therapy (median, 82.0 Gy; range, 75-89.5 Gy). RESULTS The 5-year actuarial survival rate for the 46 patients, patients with T1 (n = 23), and those with T2-T4 (n = 23) was 34%, 55%, and 13%, respectively. The 5-year disease-specific survival rate for the 46 patients, those with T1, and those with T2-T4 was 67%, 95%, and 33%, respectively. The 5-year local control rate for patients with T1 and T2-T4 lesions was 83% and 29%, respectively. The site of the first relapse was locoregional for 16 patients and distant organs for 2 patients. CONCLUSION The results suggest that proton beam therapy is an effective treatment for patients with locally confined esophageal cancer. Additional studies are required to determine the optimal total dose, fractionation schedule, and best combinations of protons and conventional X-rays with or without chemotherapy.

Abstract
PURPOSE To evaluate clinical results of proton beam therapy for patients with skull base chordoma. METHODS AND MATERIALS Thirteen patients with skull base chordoma who were treated with proton beams with or without X-rays at the University of Tsukuba between 1989 and 2000 were retrospectively reviewed. A median total tumor dose of 72.0 Gy (range, 63.0-95.0 Gy) was delivered. The patients were followed for a median period of 69.3 months (range, 14.6-123.4 months). RESULTS The 5-year local control rate was 46.0%. Cause-specific, overall, and disease-free survival rates at 5 years were 72.2%, 66.7%, and 42.2%, respectively. The local control rate was higher, without statistical significance, for those with preoperative tumors <30 mL. Partial or subtotal tumor removal did not yield better local control rates than for patients who underwent biopsy only as the latest surgery. CONCLUSION Proton beam therapy is effective for patients with skull base chordoma, especially for those with small tumors. For a patient with a tumor of <30 mL with no prior treatment, biopsy without tumor removal seems to be appropriate before proton beam therapy.

Abstract
Successful cancer patient survival and local tumor control from hadron radiotherapy warrant a discussion of potential secondary late effects from the radiation. The study of late-appearing clinical effects from particle beams of protons, carbon, or heavier ions is a relatively new field with few data. However, new clinical information is available from pioneer hadron radiotherapy programs in the USA, Japan, Germany and Switzerland. This paper will review available data on late tissue effects from particle radiation exposures, and discuss its importance to the future of hadron therapy. Potential late radiation effects are associated with irradiated normal tissue volumes at risk that in many cases can be reduced with hadron therapy. However, normal tissues present within hadron treatment volumes can demonstrate enhanced responses compared to conventional modes of therapy. Late endpoints of concern include induction of secondary cancers, cataract, fibrosis, neurodegeneration, vascular damage, and immunological, endocrine and hereditary effects. Low-dose tissue effects at tumor margins need further study, and there is need for more acute molecular studies underlying late effects of hadron therapy.

Abstract
PURPOSE To evaluate the toxicity and antitumor effect of carbon ion radiotherapy for hepatocellular carcinoma within a Phase I-II trial. METHODS AND MATERIALS Between June 1995 and February 1997, 24 patients with histopathologically proven hepatocellular carcinoma were treated to 15 fractions within 5 weeks in a step-wise dose-escalation study. The disease stage was Stage II in 10, IIIA in 6, and IVA in 8 patients. The Common Toxicity Criteria, Radiation Therapy Oncology Group/European Organization for the Research and Treatment of Cancer criteria, and Child-Pugh score were used to evaluate toxicity. The antitumor effect was evaluated by the tumor response, cumulative local control, and survival rates. RESULTS During a median follow-up of 71 months (range, 63-83 months), no severe adverse effects and no treatment-related deaths occurred. The Child-Pugh score did not increase by >2 points after the start of therapy. In 78% and 75% of all patients, the score did not increase by >1 point in the early and late phase, respectively. The overall tumor response rate was 71%. The local control and overall survival rate was 92% and 92%, 81% and 50%, and 81% and 25% at 1, 3, and 5 years, respectively. CONCLUSION Carbon ion radiotherapy appears safe and effective for patients with hepatocellular carcinoma. Additional clinical studies using a larger subject group are required to confirm the therapeutic efficacy.

Abstract
PURPOSE To analyze the radioresponse of hepatocellular carcinomas (HCC), using accurate measurements of the tumor size in extrahepatic lymph node metastasis, and to obtain information for the future treatment of primary intrahepatic lesions. MATERIALS AND METHODS Fifty-one extrahepatic lymph node metastases from primary HCCs, which could be treated by external radiotherapy alone, were included in this study. The radiation dose ranged from 30 to 51 Gy with fraction sizes of 2.0 approximately 3.0 Gy. Responses were determined by measuring the areas on CT scans 0, 1 and 3 months after the completion of radiotherapy. The median follow-up period of the surviving patients was 10 months. RESULTS The overall response rate was 76%, and the important factors were; total dose of radiation, time dose fractionation (TDF) value and the biologically effective dose (BED). A dose of 45 Gy or higher showed an objective response rate of 93%, and if the TDF value was higher than 90, a similar result was observed. In about half (47%) of the patients the maximum response was observed at 3 months or later. The response duration was observable in 14 patients surviving 12 months or longer. Regrowth of irradiated lesions were observed in 4 (66.7%) patients among those who received less than 45 Gy, and in 4 (50%) among those who were treated with 45 Gy or more. There was a statistically significant difference in the survivals between the responders and non-responders (p=0.008). Gastrointestinal bleeding or ulceration was observed in 8 patients, including 3 with NCI common toxicity criteria grade III or higher. CONCLUSION Radiotherapy was an effective palliative modality for extrahepatic metastasis in HCCs. A radiation dose of 45 Gy or higher (or a TDF value >or=90), was required for a major response.

Abstract
PURPOSE The human liver is known to be a relatively radiosensitive organ that develops clinically relevant late radiation hepatitis subsequent to whole liver treatment with total doses above 30 Gy in conventional fractionation. Experimental data, as well as clinical series, have demonstrated that hyperthermia of solid tumors in addition to radiotherapy enhances tumor growth inhibition and tumor control probability. We therefore developed an experimental model for combined radiotherapy and hyperthermia of the liver in transplantable rat Morris hepatoma 3924A. METHODS AND MATERIALS A cube of approximately 8 mm(3) was implanted subcapsularly into the middle liver lobe of 59 male syngenic ACI rats weighing approximately 180-200 g. On Day 16 after tumor implantation, irradiation of the tumor-bearing liver with either 0 Gy/25 Gy/35 Gy/45 Gy total dose in 10 fractions +/- hyperthermia (target temperature 40-42 degrees C) twice a week was initiated. Energy deposition was monitored by temperature probes in the liver and esophagus of the rats. Determination of tumor volume with magnetic resonance imaging was performed 2 to 5 weeks after the end of therapy. The tumor growth rates could be estimated for 44 rats. If the growth rate was positive (37 rats), the inverse of the growth rate was interpreted as the time to 10-fold tumor volume. Otherwise the maximum observation time was considered as a censored value in a parametric survival analysis. RESULTS Intrahepatic temperature probes showed a temperature plateau of greater than 40 degrees C after 5 to 8 min subsequent to initiation of hyperthermia. The target temperatures could be maintained for at least 22 min > or =40 degrees C and 10 min > or =41 degrees C, respectively. Median plateau temperature in liver, esophagus, and epicutaneously was 41.2 degrees C (standard deviation [SD] 0.7 degrees C; range 38.2 to 43.3 degrees C), 40.4 degrees C (SD 1.08 degrees C; range 38.9 to 41.8 degrees C), and 40.8 degrees C (SD 0.8 degrees C; range 38.2 to 42.7 degrees C), respectively. Elevation of the temperature in the esophagus correlated with intrahepatic temperatures in the range of 39-42 degrees C, r = 0.957. The increase in time to 10-fold tumor volume for each step of irradiation dosage was by 34% (95% confidence interval [CI] 20% to 49%) without hyperthermia and by 60% (95% CI 47% to 80%) with hyperthermia (p < 0.0001). CONCLUSION Treatment outcome after experimental percutaneous thermoradiotherapy in intrahepatically implanted Morris hepatoma 3924A was related to total dose of irradiation and concurrently administered regional hyperthermia. An increased radiosensitivity due to hyperthermia (<42 degrees C) has to be assumed.

Abstract
BACKGROUND The therapeutic results of nonsurgical treatment for patients with hepatocellular carcinoma (HCC) have been poor, and improved treatments are needed. The authors recently developed a new technique called angiographic subsegmentectomy for the treatment of patients with small HCC. METHODS The technique includes confirming the diagnosis of small HCC using a helical computed tomography (CT) scan combined with an angiography system for identifying the tumor-feeding subsegmental hepatic artery, injecting lipiodol containing farmorubicin until it enters the portal vein in sufficient amounts, and injecting sponge particles into the hepatic artery for embolization. Occlusion of the hepatic artery with gel particles and occlusion of the portal vein by lipiodol induce infarction necrosis, which encompasses the entire tumor and the surrounding liver parenchyma. RESULTS The treatment was given to 23 patients with 30 HCC tumors that measured < 20 mm in greatest dimension. It was successful in all 23 patients. Serum alanine aminotransferase levels were elevated to a significant level in the majority of patients after treatment, mild ascites developed in three patients, and the patients complained of pain and fever posttreatment that were controlled readily. No patients developed hepatic failure. Only one patient developed recurrent disease posttreatment at 1.5 years, for a recurrence rate of 5% at 1 year and 6.6% at 1.5 years, a rate that has never been achieved with other treatment modalities. CONCLUSIONS Angiographic subsegmentectomy is a novel treatment for patients with small HCC. The results indicated that it is equivalent to undergoing small resection and is superior to conventional arterial chemoembolization.

Abstract
PURPOSE Dose escalation using three-dimensional conformal radiotherapy (3D-CRT) is based on the hypothesis that increasing the dose can enhance tumor control. This study aimed to determine whether a dose-response relationship exists in local radiotherapy for primary hepatocellular carcinoma (HCC). METHODS AND MATERIALS One hundred fifty-eight patients were enrolled in the present study between January 1992 and March 2000. The exclusion criteria included the presence of an extrahepatic metastasis, liver cirrhosis of Child class C, tumors occupying more than two-thirds of the entire liver, and a performance status on the Eastern Cooperative Oncology Group scale of more than 3. Radiotherapy was given to the field, including the tumor, with generous margin using 6- or 10-MV X-rays. The mean radiation dose was 48.2 +/- 7.9 Gy in daily 1.8-Gy fractions. The tumor response was assessed based on diagnostic radiologic examinations, including a computed tomography scan, magnetic resonance imaging, and hepatic artery angiography 4-8 weeks after the completion of treatment. Liver toxicity and gastrointestinal complications were evaluated. RESULTS An objective response was observed in 106 of 158 (67.1%) patients. Statistical analysis revealed that the total dose was the most significant factor associated with the tumor response. The response rates in patients treated with doses <40 Gy, 40-50 Gy, and >50 Gy were 29.2%, 68.6%, and 77.1%, respectively. Survivals at 1 and 2 years after radiotherapy were 41.8% and 19.9%, respectively, with a median survival time of 10 months. The rate of liver toxicity according to the doses <40 Gy, 40-50 Gy, and >50 Gy was 4.2%, 5.9%, and 8.4%, respectively, and the rate of gastrointestinal complications was 4.2%, 9.9%, and 13.2%, respectively. CONCLUSIONS The present study showed the existence of a dose-response relationship in local radiotherapy for primary HCC. Only the radiation dose was a significant factor for predicting an objective response. The results of this study showed that 3D-CRT can theoretically be used for treating primary HCC.

Abstract
Transcatheter arterial chemoembolization (TACE) is used in the treatment of hepatocellular carcinoma; however, it has limited effect on portal vein tumor thrombus (PVTT). The purpose of this study was to assess the feasibility and efficacy of radiotherapy targeting the PVTT after TACE for the tumor in the hepatic parenchyma. TACE was performed using epirubicin hydrochloride, iodized poppy seed oil, and gelatin sponge particles. Radiotherapy was performed targeting the PVTT to a total dose of 50 Gy in 25 fractions during 5 weeks. Twenty consecutive patients were treated with this combined treatment. Sixteen of 20 patients could complete the planned radiotherapy. Partial response was observed in 10, no change in 4, and progression in 6. The response rate was 50% (95% CI 28-72%). The 1-year overall survival rate was 25% (95% CI 6-44%), and the median survival time was 5.3 months. It was difficult to determine the late toxicities because of disease progression and additional TACE, and only one patient died without disease progression. Radiotherapy after TACE is feasible for patients with hepatocellular carcinoma and PVTT. The survival figure, however, is still dismal, and further investigation is needed to establish the best combination of treatment modalities.

Abstract
Primary hepatocellular cancer is a disease with a poor prognosis for which there is little consensus on treatment and a paucity of comparative trials. The coexistence of cancer with cirrhosis complicates treatment, and also confers a high risk for the development of further tumours. Surgery, either by hepatic resection or orthotopic liver transplantation, is only a feasible option in a minority of patients. This article surveys the non-surgical approaches to the treatment of hepatocellular cancers-local ablation techniques, arterial embolization with and without chemotherapy, conventional chemotherapy and hormonal modulation, and targeted and external irradiation.

Abstract
Treatment options have largely been selected according to empirical criteria, such as the presence or absence of cirrhosis, number and size of tumors, and degree of hepatic deterioration and taking into account the local technological and economic resources. There are virtually no controlled studies comparing the efficacy of the available treatments, and the substantial heterogeneity of survival between control groups does not allow us to obtain therapeutic evaluation by comparing results of separate trials. The reassessment of treatment outcomes on the basis of intention-to-treat analysis yielded less encouraging figures. Hepatic resection is the primary option for the few patients with a hepatocellular carcinoma arising in a normal liver with well-preserved hepatic function and for patients with a single tumor, compensated cirrhosis and low portal hypertension who are not candidable to liver transplantation. The latter is the best treatment modality for patients with a solitary tumor <5 cm in diameter or patients with less than three tumors <3 cm, resulting in a 5-year survival of 75%. Locoregional ablative treatments are curative options for patients with a "resectable" tumor who cannot be offered transplantation or hepatic resection. The 5-year survival is approximately 50% but it copes with a high risk of tumor recurrence. Patients with advanced tumor disease cannot be offered curative treatments but only symptomatic treatments.

Abstract
AIM The aim of this study was to examine the effectiveness and toxicity of radiation therapy in combination with transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) with extensive portal vein tumor thrombus (PVTT). METHODS The combined therapy was performed in 24 HCC patients with extensive PVTT. External radiation targeted for PVTT (50 Gy in 2 Gy fractions) was performed in combination with repetitive TACE for intralobar lesions using 30-60 mg epirubicin every 3 months, and associations of the following variables with the survival rate were evaluated: gender, age, viral etiology, Child's class, performance status, extrahepatic metastasis, size and number of HCC, and location of PVTT. RESULTS The local response confined to PVTT was complete response (CR) in four patients, partial response (PR) in eight patients, no change (NC) in eight patients, and progressive disease (PD) in four patients. By using the stepwise Cox's regression analysis, only Child's class was associated with the survival rate. The survival rates after 1 and 2 years were 73 and 21% in Child's A, 10 and 0% in Child B or C, and 61 and 21% in patients in whom the local response was CR or PR, and 19 and 9% in those in whom the local response was NC or PD, respectively. By using the multiple logistic regression analysis, Child's class was the only factor associated with the local response (P = 0.006). CONCLUSIONS The combined therapy is feasible and may be useful to reverse PVTT in patients with good hepatic function reserve.

Abstract
The objective of this study was to assess the value of MR imaging in the differentiation between a recurrent hepatocellular carcinoma (HCC) and a radiation-induced hepatic injury. Nine male patients with suspected recurrence after radiotherapy for HCC underwent T(2)-, T(1)-weighted imaging and Gd-DTPA enhanced dynamic studies. T(2) relaxation times, signal intensity ratios in T(1)-weighted images (WI) and the relative enhancement of the dynamic study were calculated. Recurrent tumors and the irradiated area showed similar image characteristics: hypointense in T(1)-WI and hyperintense in T(2)-WI. T(2) values and signal intensity ratios in the T(1)-WI were not significantly different. In the gadolinium-enhanced dynamic study, a recurrent HCC showed early enhancement, followed by a rapid washout. However, the irradiated liver parenchyma showed hyperintensity from an early phase, and contrast enhancement tended to be more prominent and prolonged at the end of the dynamic studies. The characteristic findings of the dynamic MR study enable us to distinguish between a recurrent HCC and a radiation-induced hepatic injury.

Abstract
OBJECTIVE We assessed the role of dynamic CT in the evaluation of the efficacy of transarterial chemoembolization with iodized oil for hepatocellular carcinoma. MATERIALS AND METHODS We examined 41 hepatocellular carcinoma lesions (mean diameter, 5.0 cm) in 40 patients (mean age, 60.6 years) who underwent transarterial injection of iodized oil alone (n = 3) or emulsion of iodized oil and doxorubicin hydrochloride (n = 10) followed by gelatin sponge particles (n = 27) and subsequent hepatectomy. On dynamic CT performed within 3 weeks before oily transarterial chemoembolization and within 4 weeks before surgery, we calculated the rate of necrosis on the basis of the assumption that the portion that retained iodized oil represented necrosis. We also calculated the reduction rate of the tumor. CT findings were compared with pathologic findings of resected specimens. RESULTS Pathologic specimens and the necrosis rate measured on CT showed a good correlation (r = 0.83) when the portion of tumor that retained iodized oil was considered necrosis. No correlation existed if the portion that retained iodized oil was considered viable. We noted no significant correlation (r = 0.38) between the reduction rate of the tumor and necrosis rate. Also, we noted no correlation (r = 0.52) between the interval between transarterial oily chemoembolization and surgery and the reduction rate of the tumor. CONCLUSION CT is suitable for the evaluation of the efficacy of oily chemoembolization for hepatocellular carcinoma on the basis of the assumption that the portion of tumor that retains iodized oil is necrotic. The rate of tumor size reduction measured on CT did not correlate with the therapeutic effect of chemoembolization.

Abstract
PURPOSE The purpose of this study was to investigate the efficacy of local radiotherapy (RT) as a salvage treatment for unresectable hepatocellular carcinoma (HCC) patients who failed with transcatheter arterial chemoembolization (TACE). METHODS AND MATERIALS Patients with unresectable HCC who had been treated with and eventually failed with TACE were eligible. The judgment of TACE failure was based on incomplete tumor filling of lipiodol-adriamycin mixture on either angiography or computed tomography (CT) scan. From January 1993 to December 1997, 27 patients were entered into this study. They had UICC Stage III (17) or IVA (10) disease, with a mean tumor size of 7.2 +/- 2.9 cm. Local RT was done, with a mean tumor dose of 51.8 +/- 7.9 Gy, in daily 1.8-Gy fractions using a 10- or 6-MV linear accelerator. Survival was calculated from both the diagnosis and the start of RT using the Kaplan-Meier method. RESULTS An objective response was observed in 16 of 24 patients (66.7%) including 1 CR. Intrahepatic metastasis was noted outside the RT field in 10 patients (37.0%). Extrahepatic distant metastasis occurred in 4 patients. Survival rates at 1, 2, and 3 years were 85. 2%, 58.1%, and 33.2%, respectively, from the diagnosis and 55.9%, 35. 7%, and 21.4%, respectively, from the start of RT. The median survivals were 26 months from the diagnosis and 14 months from the start of RT. Acute toxicity involved alteration in liver function test (13 patients) and thrombocytopenia (2 patients). Subacute and chronic toxicity involved gastroduodenal ulcer (3 patients) and duodenitis (2 patients). There was no treatment-related death. CONCLUSION In unresectable HCC patients who failed with TACE, local RT induced a substantial tumor response of 66.7%, with a 3-year survival rate of 21.4% and a median survival time of 14 months. Toxicity was significant but manageable. Although we do not know if there is survival benefit through this treatment, local RT in these patients seems to be valuable as a salvage for TACE-failed HCC.

Abstract
The objective of this study was to describe magnetic resonance (MR) findings with a 1.5T imager for hepatic parenchymal changes after proton beam radiotherapy. Thirty-two patients who received proton radiotherapy with doses of 50-87 Gy underwent MR imaging 1-75 months (mean 22 months) after the start of irradiation. Axial T(2), T(1)-weighted imaging, and a dynamic study after a gadolinium injection were performed. The irradiated areas showed hypointense in T(1)-weighted images, hyperintense in T(2)-weighted images, and intense and prolonged enhancement on the dynamic study (maximum relative enhancement 441.8%+/-263.3 vs. surrounding liver 145.6%+/-67.7, p<0.0001). T(2) values of the irradiated areas were 50.6 to 65.8 msec greater than in the surrounding liver (p<0.005). The values increased with time, being significantly greater 13 months or longer after the beginning of the therapy than after a period of less than 3 months (p<0.05). Pathologic examinations (n = 3) indicated that the irradiated areas were composed of collapsed lobules with hepatic small vein occlusions, and rich extracellular matrices which retained extracellular fluid. MR imaging can demonstrate hepatic parenchymal changes after proton beam radiotherapy, and show the changes are irreversible.
