Basidiobolus ranarum is known to cause subcutaneous mycoses; however, rare cases of hepatic and gastrointestinal involvement by basidiobolomycosis have been reported. Hepatic basidiobolomycosis may be confused with a carcinoma on imaging, and histological examination and fungal culture can help distinguish between these two. We report a rare case of basidiobolomycosis in a 16-year-old male with liver and gastrointestinal involvement.
Recently, the superiority of atezolizumab plus bevacizumab (AteBeva) over sorafenib was proven in the IMbrave150 trial, and AteBeva became the first-line systemic treatment for untreated, unresectable hepatocellular carcinoma (HCC). While the results are encouraging, more than half of patients with advanced HCC are still being treated in a palliative setting. Radiotherapy (RT) is known to induce immunogenic effects that may enhance the therapeutic efficacy of immune checkpoint inhibitors. Herein, we report the case of a patient with advanced HCC with massive portal vein tumor thrombosis treated with a combination of RT and AteBeva, who showed near complete response in tumor thrombosis and favorable response to HCC. Although this is a rare case, it shows the importance of reducing the tumor burden via RT to combination immunotherapy in patients with advanced HCC.

There are various methods for treating advanced hepatocellular carcinoma with portal vein invasion, such as systemic chemotherapy, transarterial chemoembolization, transarterial radioembolization, and concurrent chemoradiotherapy. These methods have similar clinical efficacy but are designed with a palliative aim. Herein, we report a case that experienced complete remission through “associating liver partition and portal vein ligation for staged hepatectomy (ALPPS)” after concurrent chemoradiotherapy and hepatic artery infusion chemotherapy. In this patient, concurrent chemoradiotherapy and hepatic artery infusion chemotherapy induced substantial tumor shrinkage, and hypertrophy of the nontumor liver was sufficiently induced by portal vein ligation (stage 1 surgery) followed by curative resection (stage 2 surgery). Using this approach, long-term survival with no evidence of recurrence was achieved at 16 months. Therefore, the optimal use of ALPPS requires sufficient consideration in cases of significant hepatocellular carcinoma shrinkage for curative purposes.

Treatment options for advanced hepatocellular carcinoma (HCC) have been rapidly evolving. Herein, we describe a patient with advanced HCC and portal vein tumor thrombosis (PVTT) who responded decisively to a multidisciplinary approach. The patient had an ill-defined infiltrative HCC (diffuse subtype), with several intrahepatic metastasis and tumor invasion of left portal vein. Concurrent use of transarterial radioembolization (TARE) and systemic therapeutics (atezolizumab + bevacizumab) ultimately proved successful. There was marked reduction in tumor volume after TARE and an additional three cycles of atezolizumab plus bevacizumab. This concurrent treatment was well tolerated, without adverse events during immunotherapy. The impressive results achieved suggest that concurrent TARE and combination atezolizumab/bevacizumab is a promising treatment approach for advanced HCC with PVTT.
