Purpose To describe outcomes of prospective trials of stereotactic body radiotherapy (SBRT) for hepatocellular carcinoma (HCC). Patients and Methods Two trials of SBRT for patients with active HCC unsuitable for standard locoregional therapies were conducted from 2004 to 2010. All patients had Child-Turcotte-Pugh class A disease, with at least 700 mL of non-HCC liver. The SBRT dose range was 24 to 54 Gy in six fractions. Primary end points were toxicity and local control at 1 year (LC1y), defined as no progressive disease (PD) of irradiated HCC by RECIST (Response Evaluation Criteria in Solid Tumors). Results A total of 102 patients were evaluable (Trial 1, 2004 to 2007: n = 50; Trial 2, 2007 to 2010: n = 52). Underlying liver disease was hepatitis B in 38% of patients, hepatitis C in 38%, alcohol related in 25%, other in 14%, and none in 7%. Fifty-two percent received prior therapies (no prior sorafenib). TNM stage was III in 66%, and 61% had multiple lesions. Median gross tumor volume was 117.0 mL (rang...

Sequential Phase I and II Trials of Stereotactic Body Radiotherapy for Locally Advanced Hepatocellular Carcinoma

The NCCN Guidelines for Hepatobiliary Cancers focus on the screening, diagnosis, staging, treatment, and management of hepatocellular carcinoma (HCC), gallbladder cancer, and cancer of the bile ducts (intrahepatic and extrahepatic cholangiocarcinoma). Due to the multiple modalities that can be used to treat the disease and the complications that can arise from comorbid liver dysfunction, a multidisciplinary evaluation is essential for determining an optimal treatment strategy. A multidisciplinary team should include hepatologists, diagnostic radiologists, interventional radiologists, surgeons, medical oncologists, and pathologists with hepatobiliary cancer expertise. In addition to surgery, transplant, and intra-arterial therapies, there have been great advances in the systemic treatment of HCC. Until recently, sorafenib was the only systemic therapy option for patients with advanced HCC. In 2020, the combination of atezolizumab and bevacizumab became the first regimen to show superior survival to sorafenib, gaining it FDA approval as a new frontline standard regimen for unresectable or metastatic HCC. This article discusses the NCCN Guidelines recommendations for HCC.

Hepatobiliary Cancers, Version 1.2017: Featured Updates to the NCCN Guidelines

Background. Since 2005, we have treated hepatocellular carcinoma (HCC) with stereotactic body radiotherapy (SBRT) uniformly at two dose levels, according to baseline liver function and normal liver dose. We retrospectively examined the outcomes for these patients. Material and methods. Between 2005 and 2012, 221 HCC patients were treated with SBRT. Eligibility criteria for SBRT included a single (either solitary or recurrent) HCC lesion; unfeasible, difficult or refusal to undergo other surgery or percutaneous ablative therapies; Child-Pugh Classification (CPC) A or B; tumors ≤ 5 cm; dose to the bowels < 25 Gy/5 fractions; curative intent. Patients followed up ≥ 6 months were eligible. The prescribed dose depended on liver function and liver dose: 40 Gy for CPC-A and 35 Gy for CPC-B, in 5 fractions, requiring a 5-Gy dose reduction if the proportion of the liver receiving ≥ 20 Gy exceeded 20%. Treatment outcomes and safety were analyzed. Results. A total of 185 patients (n = 48 in the 35-Gy group; ...

Stereotactic body radiotherapy for small hepatocellular carcinoma: a retrospective outcome analysis in 185 patients.

BACKGROUND:

The objective of this study was to evaluate the efficacy and safety of stereotactic body radiation therapy (SBRT) as a local salvage treatment after incomplete transarterial chemoembolization (TACE) for inoperable hepatocellular carcinoma (HCC).



METHODS:

The main eligibility criteria were a greatest tumor dimension (LD sum) <10 cm, inoperable HCC, and incomplete response after TACE. Prescribed SBRT doses were up to 60 gray (Gy) in 3 fractions, but doses were reduced until normal tissue constraints were allowed.



RESULTS:

Between May 2008 and February 2011, 50 patients were enrolled in this phase 2 trial, of which 47 patients were evaluable. Forty-one patients had Child-Pugh class A disease (A5/A6 were 32/9), 6 patients had class B7 disease, and 5 patients had portal vein tumor thrombosis. All patients underwent TACE 1 to 5 times before SBRT. SBRT doses ranged from 42 to 60 Gy in 3 fractions (median dose, 57 Gy), and the median LD sum was 29 mm (range, 13-78 mm). Eighteen patients (38.3%) achieved complete remission within 6 months of completing of SBRT, and 18 patients (38.3%) had a partial response. The 2-year local control rate was 94.6%, the overall survival rate was 68.7%, and the progression-free survival rate was 33.8%. Three patients (6.4%) experienced grade 3 gastrointestinal toxicity, and 2 patients (4.3%) experienced grade 4 gastric ulcer perforation.



CONCLUSIONS:

This trial demonstrated that SBRT after incomplete TACE for inoperable HCC achieves promising rates of response and local control. On the basis of these study results, a modified, multi-institutional, phase 2 trial to reduce gastrointestinal toxicity is recommended. Cancer 2012. © 2012 American Cancer Society.

Stereotactic body radiation therapy for inoperable hepatocellular carcinoma as a local salvage treatment after incomplete transarterial chemoembolization

PURPOSE To report the results of stereotactic body radiotherapy (SBRT) for unresectable primary or recurrent cholangiocarcinoma. MATERIALS AND METHODS From January 2005 through August 2013, 58 patients with unresectable primary (n = 28) or recurrent (n = 30) cholangiocarcinoma treated by SBRT were retrospectively analyzed. The median prescribed dose was 45 Gy in 3 fractions (range, 15 to 60 Gy in 1-5 fractions). Patients were treated by SBRT only (n = 53) or EBRT + SBRT boost (n = 5). The median tumor volume was 40 mL (range, 5 to 1,287 mL). RESULTS The median follow-up duration was 10 months (range, 1 to 97 months). The 1-year, 2-year overall survival rates, and median survival were 45%, 20%, and 10 months, respectively. The median survival for primary group and recurrent group were 5 and 13 months, respectively. Local control rate at 1-year and 2-year were 85% and 72%, respectively. Disease progression-free survival rates at 1-year and 2-year were 26% and 23%, respectively. In univariate analysis, ECOG performance score (0-1 vs. 2-3), treatment volume ( 12 months interval from surgery to recurrence showed statistically significant higher overall survival rate than those with ≤12 months (p = 0.026). Six patients (10%) experienced ≥grade 3 complications. CONCLUSION SBRT can be considered as an effective local modality for unresectable primary or recurrent cholangiocarcinoma.

Outcomes of stereotactic body radiotherapy for unresectable primary or recurrent cholangiocarcinoma.

Transduodenal ampullectomy (TDA) is the treatment of choice for large premalignant lesions of the ampulla of Vater (AoV). With the development of surgical techniques, various methods, including the open, laparoscopic, and robotic approaches, for performing TDA have emerged. Herein, we report four consecutive cases treated with open, laparoscopic, and robotic TDA, with technical pitfalls and future perspectives of TDA in treating premalignant lesions of the AoV. The surgical techniques and principles for TDA were the same regardless of the surgical approaches. After surgery, none of the patients showed any abnormal findings or complications, except for digestive problems. All these surgical approaches are appropriate for patients requiring TDA; however, minimally invasive TDA, particularly the robotic approach is ideal. Considering the surgical complexity of TDA, the robotic approach is considered to be effective.

Most familial adenomatous polyposis (FAP) patients undergo total colectomy, but duodenal polyposis develops in up to 90% of patients with FAP and a 4% to 18% risk of duodenal and ampullary cancer remains. Laparoscopic pancreas-preserving near total duodenectomy is thought to be a potential option and can be an effective approach to preserve the pancreas. A 48-year-old male patient, who underwent laparoscopic total colectomy with end ileostomy because of FAP with colorectal cancer, was diagnosed with a 20 mm-sized duodenal adenoma in the second to the third portion. The operation was performed on December 27, 2021. Near total duodenectomy was done and type II Billroth gastrojejunostomy was done. Laparoscopic pancreas-sparing duodenectomy is shown to be safe, with favorable short-term oncologic outcome compared to laparoscopic pancreatoduodenectomy in terms of less blood loss, faster recovery time, and much less total cost.
