A study was conducted to evaluate the effect of external radiation therapy on hepatocellular carcinoma (HCC) and its metastatic lesions. A total of 33 patients with cytopathologically proven HCC were subjected to radiation therapy over a 4-year period, and treatment was discontinued in 8 cases due to jaundice, severe discomfort, or early mortality. Thus, 25 patients with 28 lesions underwent irradiation with a total dose ranging between 3000 and 5600. Of these, seven were irradiated for liver tumors, and the results showed that two lesions decreased in size, the symptoms improved in 1 case, and another patient maintained stable disease for 4 months. Among the 21 metastatic lesions treated, only 2 patients failed respond to the treatment. Nine subjects were irradiated for bone metastases, and the bone pain subsided in all but one case. The survival for bone metastasis was as long as 23 months when the primary tumor was treated effectively. Three of the four cases of irradiated skin nodules disappeared and had not recurred after 5 months, 1 year, and 4 years, respectively. Tumor shrinkage or symptoms of relief were noted for three abdominal lymph nodes, one neck lymph node, one pleural tumor, and one lung tumor. Clinical improvement associated with a stable lesion was observed in two patients with brain metastasis. Follow-up revealed regrowth of the tumor or recurrence of symptoms in most of the patients. However, none of the patients died as a direct result of a metastatic lesion. Although external radiation therapy is palliative in intent, it appears to be useful in the treatment of HCC and its metastatic lesions.

Alendronate, a bisphosphonate compound, lowers serum calcium in patients with cancer-associated hypercalcemia through its inhibitory effect on bone resorption and as a result symptoms associated with hypercalcemia improve. This study was carried out to investigate the effects of alendronate in patients with hypercalcemia due to bone metastasis of hepatocellular carcinoma (HCC). Two patients were evaluated. Their corrected serum calcium and alpha-fetoprotein (AFP) levels and their computed tomography (CT), bone scintigraphy and magnetic resonance imaging (MRI) findings were evaluated before and during alendronate treatment. After treatment, not only the corrected serum calcium levels but also AFP levels and bone pain decreased; in addition, the regression of the metastatic focus was noted in the MRI analysis. These tumor inhibitory effects of alendronate have not been reported in HCC before; and alendronate might serve to prevent bone metastases in patients with HCC. In conclusion, two patients who developed hypercalcemia associated with bone metastasis after surgery for HCC were treated with alendronate and they experienced alleviation of the pain due to bone metastasis, improvement of their quality of life and a marked decrease in AFP levels with tumor regression.

Pain from bone metastases limits mobility and may cause pathological fractures that can seriously impair the patient's quality of life. Conservative treatments such as orthopedic fixation, radiotherapy, and opioids sometimes fail to give satisfactory pain relief. Bisphosphonates have been reported to reduce the severity of pain from bone metastasis due to breast cancer, prostate cancer, and multiple myeloma. Recent clinical reports demonstrated the effectiveness of bisphosphonates in reducing pain from bone metastases in various malignancies. This study presents 3 cases of refractory pain from bone metastases due to thyroid, colorectal and hepatocellular carcinoma. Primary treatment included orthopedic fixation, radiotherapy, and/or parenteral opioids that failed to reduce bone pain. Bisphosphonate therapy was considered at the start of pain control treatment using opioids. All 3 cases showed gradual reduction in pain after i.v. pamidronate administration and allowed physicians to control further pain with opioids. In 1 case, the patient was successfully withdrawn from opioids. The role of bisphosphonates in painful bone metastases remains unclear. However, recent encouraging reports have indicated that bisphosphonate may become one of the adjuvant treatments available to control refractory bone pain from various malignancies.

Although radiotherapy is highly effective in relieving bone pain from cancer invasion, the mechanism of pain relief remains unclear. To explore the mechanism of radiotherapy-induced analgesia, we have developed an animal model of bone pain resulting from cancer invasion. Using this animal model system, radiation-induced pain response and pain-related signals in the spinal cord were analyzed. The hind paw model of bone pain from cancer invasion was developed by injecting transplantable hepatocellular carcinoma, HCa-1, into the periosteal membrane of the foot dorsum in C3H/HeJ mice. Bony invasion from HCa-1 cells was confirmed by histopathological examinations. We also measured the development of pain-associated behaviors. In this model, changes in the objective level of pain response after irradiation of the tumor were analyzed. Expression of pain-related host signals in the spinal cord, such as calcitonin gene-related peptide (CGRP), substance P, and c-fos, was investigated with immunohistochemical staining. In the histopathological examinations, bone invasion from HCa-1 cells was seen from day 7 and was evident at day 14 after injection. Measurable pain-associated behaviors were developed from day 7. In this model, mice treated with radiotherapy showed decreased objective levels of pain with a higher threshold to graded mechanical stimulation than did control mice from day 3 after irradiation. After irradiation of tumors, significant decreases in the expression of CGRP were shown in the spinal cord, whereas neither substance P nor c-fos showed any alteration. We developed a novel hind paw model of bone pain from cancer invasion that was confirmed by histopathological examination and measurable pain-associated behaviors. Radiotherapy decreased the objective level of pain and the underlying mechanism involved in the alteration of pain-related host signal, CGRP, in the spinal cord.

For more than 50 years now, nuclear medicine has offered therapeutic procedures in oncology. These comprise bone pain palliation in bone metastases of prostate and breast cancer. For more than 20 years now, metaiodobenzylguanidine (mIBG) has been used to treat neuroendocrine tumors. Ten years ago, somatostatin analogues such as Y-90 Dotatoc became available for the treatment of somatostatin receptor-positive tumors. The intracavitary injection of radiocolloids has been well known for 5 decades now and can be used in malignant effusions. Invasive procedures such as intra-arterial injection of I-131 lipiodol may be applied in multifocal, nonresectable hepatocellular carcinoma. Beyond that, intratumoral injection of radioisotopes may be used in cutaneous metastases. Radioimmunotherapy using labeled tumor antibodies is now also available, especially in patients with non-Hodgkin's lymphoma.

Transcatheter arterial chemoembolization (TACE) has been used widely to treat patients with unresectable hepatocellular carcinoma. However, this method can induce various adverse events caused by necrosis of the tumor itself or damage to nontumor tissues. In particular, neurologic side effects such as cerebral infarction and paraplegia, although rare, may cause severe sequelae and permanent disability. Detailed information regarding the treatment process and prognosis associated with this procedure is not yet available. We experienced a case of paraplegia that occurred after conducting TACE through the intercostal artery to treat hepatocellular carcinoma that had metastasized to the rib. In this case, TACE was attempted to relieve severe bone pain, which had persisted even after palliative radiotherapy. A sudden impairment of sensory and motor functions after TACE developed in the trunk below the level of the sternum and in both lower extremities. The patient subsequently received steroid pulse therapy along with supportive care and continuous rehabilitation. At the time of discharge the patient had recovered sufficiently to enable him to walk by himself, although some paresthesia and spasticity remained.

Radionuclide therapy (RNT) based on the concept of delivering cytotoxic levels of radiation to disease sites is one of the rapidly growing fields of nuclear medicine. Unlike conventional external beam therapy, RNT targets diseases at the cellular level rather than on a gross anatomical level. This concept is a blend of a tracer moiety that mediates a site specific accumulation followed by induction of cytotoxicity with the short-range biological effectiveness of particulate radiations. Knowledge of the biochemical reactions taking place at cellular levels has stimulated the development of sophisticated molecular carriers, catalyzing a shift towards using more specific targeting radiolabelled agents. There is also improved understanding of factors of importance for choice of appropriate radionuclides based on availability, the types of emissions, linear energy transfer (LET), and physical half-life. This article discusses the applications of radionuclide therapy for treatment of cancer as well as other diseases. The primary objective of this review is to provide an overview on the role of radionuclide therapy in the treatment of different diseases such as polycythaemia, thyroid malignancies, metastatic bone pain, radiation synovectomy, hepatocellular carcinoma (HCC), neuroendocrine tumors (NETs), non-Hodgkin's lymphoma (NHL) and others. In addition, recent developments on the systematic approach in designing treatment regimens as well as recent progress, challenges and future perspectives are discussed. An examination of the progress of radionuclide therapy indicates that although a rapid stride has been made for treating hematological tumors, the development for treating solid tumors has, so far, been limited. However, the emergence of novel tumor-specific targeting agents coupled with successful characterization of new target structures would be expected to pave the way for future treatment for such tumors.

Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide, and is advanced by severe viral hepatitis B or C (HBV or HCV) as well as alcoholic liver disease. Many patients with early disease are asymptomatic therefore HCC is frequently diagnosed late requiring costly surgical resection or transplantation. The available non-invasive detections systems are based on the clinical utility of alpha fetoprotein (AFP) measurement, together with ultrasound and other more sensitive imaging techniques. The hallmark of liver disease and its propensity to develop into fully blown HCC is depended on several factors including the host genetic make-up and immune responses. While common symptoms involve diarrhea, bone pain, dyspnea, intraperitoneal bleeding, obstructive jaundice, and paraneoplastic syndrome, the evolution of cell and immune markers is important to understand viral induced liver cancers in humans. The circulating miRNA, cell and immune based HCC biomarkers are imperative candidates to successfully develop strategies to restrain liver injury. The current molecular genetics and proteomic analysis have lead to the identification of number of key biomarkers for HCC for earlier diagnosis and more effective treatment of HCC patients. In this review article, we provide latest updates on the biomarkers of HBV or HCV-associated HCC and their co-evolutionary relationship with liver cancer.

The incidence of bone metastases (BMs) from hepatocellular carcinoma (HCC) is relatively low compared to those of other cancers, but it has increased recently, especially in Asian countries. Typically, BMs from HCC appear radiologically as osteolytic, destructive, and expansive components with large, bulky soft-tissue masses. These soft-tissue masses are unique to bone metastases from HCC and often replace the normal bone matrix and exhibit expansive growth. They often compress the peripheral nerves, spinal cord, or cranial nerves, causing not only bone pain but also neuropathic pain and neurological symptoms. In patients with spinal BMs, the consequent metastatic spinal cord compression (MSCC) causes paralysis. Skull base metastases (SBMs) with cranial nerve involvement can cause neurological symptoms. Therefore, patients with bony lesions often suffer from pain or neurological symptoms that have a severe, adverse effect on the quality of life. External-beam radiotherapy (EBRT) can effectively relieve bone pain and neurological symptoms caused by BMs. However, EBRT is not yet widely used for the palliative management of BMs from HCC because of the limited number of relevant studies. Furthermore, the optimal dosing schedule remains unclear, despite clinical evidence to support single-fraction radiation schedules for primary cancers. In this review, we outline data describing palliative EBRT for BMs from HCC in the context of (1) bone pain; (2) MSCC; and (3) SBMs.

Palliation of bone metastases in hepatocellular carcinoma (HCC) is sometimes difficult. Systemic pharmaceuticals have been successfully used for the palliation of bone metastasis for many years. Safety of these agents in HCC is not known completely. We presented a male patient with decompensated liver cirrhosis with HCC. Multifocal bone metastases developed in this patient and he had refractory bone pain. We treated this patient with Sm-153 (samarium) after obtaining patient's consent. Two days after treatment, he experienced dyspnea and we detected a massive hemorrhagic pericardial effusion. He died due to this unexpected bleeding. We should use this radiopharmaceutical treatment cautiously in these cytopenic cirrhotic patients.
