Mandibular chronic osteomyelitis with diffuse osteosclerosis is recognized as an intractable infectious disease. We emplyed decortication and intraarterial infusion of antibiotics in 6 cases. Decortication on the affected mandible was performed with retrocatherization to the superficial temporal artery of affected side under general anesthesia. Antibiotics, IPM/CS or FOMX was used through the artery for 4-11 days. In addition, we administered FOMX, PIPC intravenously for 8-17 days. CT and MRI were taken postoperatively. The postoperative follow-up period ranged from 1 year and 6 months to 2 years and 5 months. Postoperative MR showed that bone marrow signal was recovered to approximately normal in 4 cases. High signal area of bone marrow and osteosclerosis image remained in 2 cases, but showed improvement. The results were satisfactory without recurrence in all of 6 cases.

A combination of 5-fluorouracil plus actinomycin D (5FU plus Act D) is the regimen that has been commonly administered to Chinese and Japanese gestational trophoblastic neoplasia patients as the first or second line of treatment with an excellent outcome. However, the efficacy of this regimen in a salvage setting was unclear. To evaluate the efficacy and safety of the 5 FU plus Act D regimen utilized in this condition, all GTN patients resistant to at least three previous chemotherapy regimens who received the 5 FU plus Act D regimen between August 2009 and January 2011 at Chiang Mai University Hospital were reviewed. There were five cases who met the criteria. Four of those patients were in FIGO stage III to IV with a WHO scoring of more than 12. The median number of cycles for each patient was two and only one case achieved remission while four of the cases were unresponsive. The toxicity was evaluated in 12 cycles. Common complications were uncomplicated myelosuppression and mucositis. In conclusion, this regimen revealed modest efficacy in a salvage setting with manageable toxicity.

A novel monoclonal antibody (mAb), known as AC10364, was identified from an antibody library generated by immunization of mice with human carcinoma cells. The mAb recognized proteins in lysates from multiple carcinoma cell lines. Cell cytotoxicity assays showed that AC10364 significantly inhibited cell growth and induced apoptosis in multiple carcinoma cell lines, including Bel/fu, KATO-III and A2780. Compared with mAb AC10364 or chemotherapeutic drugs alone, the combination of mAb AC10364 with chemotherapeutic drugs demonstrated enhanced growth inhibitory effects on carcinoma cells. These results suggest that mAb AC10364 is a promising candidate for cancer therapy.

Objectives: Advanced malignant melanoma (MM) has a poor prognosis, with an expected 2-year survival rate of 10 to 20%. It has long been recognized as an immunogenic tumor, and is worse for elderly patients. Many studies have suggested that herbal treatments improve immune functions, but few clinical studies have reported on this topic. Patients and History: We present two cases of female patients (72 and 77 years old, respectively) with advanced MM. The 72-year-old female patient was, at first, diagnosed with MM with multiple bone metastases. She received resection of the primary lesion, but refused further chemotherapy. The 77-year-old female patient was diagnosed with cutaneous MM of the left heel, with suspicion of sentinel node lymphadenopathy; however, she also refused any conventional treatment due to old age. Course of Therapy and Results: Both patients were exclusively treated with standardized allergen-removed Rhus verniciflua stokes (aRVS) extract combined with Bojungikki-tang (BT, Bu-Zhong-Yi-Qi-Tang in Chinese or Hochu-ekki-to in Japanese). Both patients are still alive and doing well (Feb. 2014), demonstrating that the 72-year-old patient has lived for 27 months and the 77-year-old patient has lived for 31 months without disease progression since the aRVS and BT administration. Conclusion: We suggest that the combination of aRVS extract and BT could be a candidate for overcoming the cancer's immunoediting process especially for elderly MM patients intolerant of conventional treatment.

The existence of primary branchiogenic carcinoma is controversial. In 1950, Martin et al. established four criteria for the diagnosis of primary branchiogenic carcinoma. In 1989, Khafif et al. proposed new modified criteria, which are currently most recognized in the literature. A 54-year-old woman presented the well-defined, fluctuant, painless mass on her left neck and underwent a complete excision under the clinical diagnosis of the branchial cleft cyst. The initial pathological impression was a branchiogenic squamous cell carcinoma. However, it did not coincide with a true primary branchiogenic carcinoma clinically. After the guided biopsy of suspicious areas found a squamous cell carcinoma of the tongue base, the patient was treated by combination chemotherapy with radiotherapy. Thus, we report this case with a review of the literature.

Alveolar soft part sarcoma, named by Christopherson in 1952, is a very rare soft tissue sarcoma. It reportedly accounts for 0.5 to 1.0% of all soft tissue sarcoma and no established treatment principle assists it. The relative lack of symptoms makes it easily overlooked and consequently early diagnosis is frequently impossible. Often, the metastasis to the lung or the brain is the first manifestation of the disease. In some cases wide excision is not performed because it is misdiagnosed as a benign tumor. Authors experienced 7 cases of alveolar soft part sarcoma in 20 years and found the ultimate prognosis grave and the treatment not promising. Therefore, the authors recommend the following; 1. Early diagnosis and early treatment are important for successful management of alveolar soft part sarcoma. 2. Preoperative incisional biopsy is necessary for pathologic diagnosis. 3. The recommended treatment modality is a combination of wide excision, chemotherapy and radiotherapy.

Although adenoid cystic carcinoma (ACC) of the lacrimal gland is a rarely encountered orbital tumor, it invades intracranially more frequently than carcinomas of other glands in the head and neck. A 52-year-old man underwent orbital exenteration and resection of intracranially extended tumor via a fronto-orbito-zygomatic approach in combination with a transfacial approach. Histopathologically, the tumor showed perineural, vascular, and lymphatic invasion. Additionally, he received radiotherapy (60 Gy) and adjuvant systemic cisplatin and 5-fluorouracil chemotherapy due to residual tumor in the orbit and systemic metastases (lung, ribs, and spines). He was free of progression and recurrence at 6 months after treatment. The authors report a case of skull base invasion by an ACC of the lacrimal gland to remind neurosurgeons planning intervention that this disease shows a tendency to invade intracranially.

Extrarenal Wilms' tumor is a very exceptional tumor which is defined as Wilms' tumor found anywhere other than in the kidneys. Until now less than 60 cases have been reported in the English literature. The tumor can be located in the retroperitoneum, inguinal canal, uterus, cervix, testes, skin and even in the thorax. The diagnosis is almost always made after surgical intervention. Distant metastasis of this tumor has only been reported in the case of a 6-year-old girl who developed Wilms' tumor in the inguinal canal with lung involvement. In this paper we report a case of extrarenal Wilms' tumor in retroperitoneum with distant metastasis to lungs, ribs and pelvic bone in a 6-year old male. The tumor was successfully removed without tumor cell spillage. The patient was diagnosed as favorable histologic group, in which the tumor consists of epithelial, blastemal and mesenchymal components without teratomatous elements. He received combination chemotherapy according to NWTS-IV guidelines and radiation to involved lungs, and has been alive and well for the last 6 months without severe complication or relapse.

Kaiso is a Pox Virus and Zinc Finger (POZ-ZF) transcription factor with bi-modal DNA-binding specificity. Here, we demonstrated that Kaiso expression is inversely correlated with glucocorticoid receptor (GR) expression in breast carcinomas. Knockdown of Kaiso increased GR expression, while overexpression of Kaiso inhibited GR expression in breast cancer cells. Furthermore, Kaiso repressed GR proximal promoter-reporter activity in a dose-dependent manner. Remarkably, ChIP experiments demonstrated that endogenous Kaiso was associated with the GR promoter sequence in a methylation-dependent manner. Since glucocorticoids inhibit chemotherapyinduced apoptosis and have been widely used as a co-treatment of patients with breast cancer, we assessed the role of Kasio in GR-mediated anti-apoptotic effects. We found that overexpression of Kaiso attenuated the anti-apoptotic effects of glucocorticoids in breast cancer cells. Our findings suggest that GR is a putative target gene of Kaiso and suggest Kaiso to be a potential therapeutic target in GC-combination chemotherapy in breast cancer.

Multi-drug resistance (MDR) has been known as a major hurdle in cancer chemotherapy. One of the most clinically significant causes of MDR was the efflux of anticancer agents mediated by p-glycoprotein (p-gp) over-expressed in MDR cancer cells. To overcome MDR, there have been several strategies such as co-administration with p-gp inhibitors and encapsulation of anticancer drugs into drug delivery systems. In the present study, curcumin was evaluated for its potential as p-gp inhibitor and MDR reversal activity when combined with paclitaxel incorporated into lipid nanoparticles (PTX/LN). Western blot assay showed curcumin did not modulate the level of p-gp expression in MCF-7/ADR which is a MDR variant of human breast cancer cell line, MCF-7, and over-expresses p-gp. However, curcumin inhibited p-gp-mediated efflux of calcein in a dose-dependent manner even though it showed lower activity compared to verapamil, a well-known p-gp inhibitor. Incorporation of paclitaxel into lipid nanoparticles partially recovered the anticancer activity of paclitaxel in MCF-7/ADR. The combined use of curcumin and PTX/LN exhibited further full reversal of MDR, suggesting susceptibility of PTX/LN to the efflux system. In conclusion, combined approach of using p-gp inhibitors and incorporation of the anticancer agents into nano-delivery systems would be an efficient strategy to overcome MDR.
