Renal cell carcinoma(RCC) is one of the major malignant renal cell tumors. Although RCC can metastasize to almost every organ, the most common metastatic sites are the lung parenchyma, the bones, the liver, and the brain. Adrenal metastasis from RCC is extremely rare. Adrenal metastasis from RCC shows poor prognosis, with little benefit from chemotherapy, radiation therapy, hormone therapy or immunotherapy. In this report, we describe a case of an RCC patient who showed lung and adrenal metastasis. The patient underwent left nephrectomy and chemotherapy(sunitinib), which were not effective. He refused further conventional medical treatment, and instead started treatment with Traditional Korean Medicine using allergen-removed Rhus verniciflua Stokes. After about 3 months of this treatment, the size of the adrenal tumor had decreased significantly with good performance status. Further study will be needed to demonstrate the tumor regression effect of allergen-removed Rhus verniciflua Stokes on patients with metastatic renal cell carcinoma.

It is well known that fine needle aspiration biopsy(FNAB) is very useful and has a high accuracy rate in the diagnosis of renal neoplasms. Although there is some indecision to perform the FNAB for a rare possibility of tumor seeding along the biopsy needle tract, it tends to be used increasingly. As in the cytologic diagnosis of metastatic lesion through-out the body, renal cell carcinoma should nearly always be considered in the differential diagnosis, the precise understanding of cytologic features of renal cell carcinoma with various cell types and architectural patterns is necessarily required. In this report, we present three cases of primary renal cell tumors, two of renal cell carcinomas and one of oncocytoma, preponderantly emphasizing the cytologic differential points in the FNAB specimen.

Renal cell carcinoma is the most common histological type of renal malignancy, predominant in men and the primary treatment modality of this tumor is surgery. The role of diagnostic imaging in the management of this tumor is the evaluation of extent of disease as well as the detection and characterization of renal mass. US has long been a routine screening tool for kidney but tomographic imaging modalities such as CT and MRI begin to be also commonly used these days. On the other hand, the sensitivity of $^{18}F-FDG-PET$ in detection of renal mass is relatively low because of inherent limitation caused by FDG excretion pathway despite avid uptake of FDG to tumor cell per se. Many studies revealed FDG PET scan could play an important role in detection of metastatic lesions although the sensitivity for the detection of primary lesion is not so high. Furthermore, development of PET/CT scanner will make it possible to expand the indication of FDG PET scan in this malignancy.

The appearance of a tumor in the chest wall is rare compared to that in any other part of the body. It can be classified into benign and malignant types and can be located in the rib, clavicle, sternum, cartilage and soft tissues. Tumors that are metastatic are commonly located in the lung, breast, bone and pleura. But, the soft tissue mass of anterior chest wall is rarely metastasized from a distant organ that is not confined to the thoracic cavity. This and thus has rarely been described. A 68-year-old man was admitted to our hospital with a chief complaint of resting dyspnea. A huge non-tender mass of about $10{\times}15$ cm in size was visible on his left lower anterior chest wall. We pathologically confirmed that the mass was a metastatic renal cell carcinoma of clear cell type by incision biopsy. Through an incision biopsy, the mass was pathologically confirmed as a metastatic renal cell carcinoma of the clear cell type.

The perception of the 20 adverse events of targeted therapy for metastatic renal cell carcinoma was compared among medical professionals. Thirty-seven oncologists, 167 nurses and 79 pharmacists participated in the survey, and the response rate was 61.9%, 98.2%, 84.9%, respectively. Results showed that the most serious adverse event was GI perforation (8.83 points, 10 being the most serious), whereas the least serious was anemia (5.32 points). There were significant differences among oncologists, nurses and pharmacists especially for the moderately-serious adverse event such as wound-healing complication and lymphopenia. Adverse Events Composite Score (AECS) for each targeted therapy was calculated by multiplying adverse event incidence rate and seriousness score. Sunitinib had the highest score at 6.86 point and bevacizumab had the lowest at 2.1. Among professional groups oncologists showed the lowest AECS, whereas nurses had the highest. The gap on the perception of the adverse events among medical professionals needs to be reduced to get better outcomes of medical therapies for cancer patients.

Background: To evaluate our results in terms of response, survival and toxicity profile of sunitinib among Egyptian patients with metastatic renal cell carcinoma. Materials and Methods: Between January 2010 and December 2013, 44 patients with metastatic renal cell carcinoma who received sunitinib at an oncology center of Cairo university hospitals were enrolled in this retrospective analysis. Results: The median age of the patients was 53 years, 22 (50%) having localized disease at presentation, while the remaining half of the patients presented with metastasis. At a median follow up of 19 months, 9 (21%) patients achieved partial remission, while disease was reported stable in 20 cases (45%) and progressive in 7 (16%), 4 (9%) being lost to follow up, and 4 (9%) had discontinued therapy due to toxicity. The median overall survival was 23 months (95%CI 15.2 - 30.9), while progression free survival was 12 months (95%CI 11.6 - 12.3). The most commonly reported non hematological grade 3 adverse events included mucositis (15.9%), hand-foot syndrome (13.6%), and fatigue (9%), while the predominant grade 3 or 4 laboratory abnormalities were neutropenia (6.8%), followed by anemia in 4.5% of patients. Conclusions: Our efficacy data were comparable to the published literature in terms of progression free survival and overall survival, while toxicity profile is different from Asian and western countries. However, sunitinib adverse events were manageable and tolerable in most of our Egyptian patients.

Purpose: Anti-cancer activity evaluation of aqueous extract of CRUEL (herbomineral formulation) capsules on renal cell carcinoma cell lines, and exploration of mechanisms of cell death. Materials and Methods: To detect the cytotoxic dose concentration in renal cell carcinoma (RCC) cells, MTT assays were performed and morphological changes after treatment were observed by inverted microscopy. Drug effects against RCC cell lines were assessed with reference to cell cycle distribution (flow cytometry), anti-metastatic potential (wound healing assay) and autophagy(RT-PCR). Results: CRUEL showed anti-proliferative effects against RCC tumor cell lines with an IC50 value of ${\approx}4mg/mL$ in vitro., while inducing cell cycle arrest at S-phase of cell cycle and inhibiting wound healing. LC3 was found to be up-regulated after drug treatment in RT-PCR resulting in an autophagy mode of cell death. Conclusions: This study provides the experimental validation for antitumor activity of CRUEL.

Background: Metastatic renal cell carcinoma (mRCC) status as poor prognosis improved with the introduction of tyrosine-kinase inhibitors, especially sunitinib. There is sparse data reporting from our region on use of sunitinib in metastatic RCC. Thus the present study explores sunitinib usage at our institute. Materials and Methods: An unselected population of patients with metastatic RCC receiving sunitinib was analyzed with respect to patient characteristics, response, toxicity, and outcomes. Results: Fourty-nine patients with a median age of 50.5 years (range 21-71 years) were included. Most were male (61.2%). Twenty‑one (42.9%) had metastatic disease at presentation. Sunitinib was first line therapy in 45. Conventional clear cell carcinoma was the most common pathology present (39 patients; 79.59 %). The most common site of metastasis was the lung (75.5%). Most patients (30) were started at a dose of 50 mg once a day for 4 weeks and then 2 weeks rest. Clinical benefit rate was 73.5% (n= 36), and 22.5% (n= 11) demonstrated progressive disease at first imaging evaluation within the first 3-6 months. The following objective response performed for patients was 48.9% (n=24) and progression at 24.5 % (n=12). The median follow‑up was 16 months (range, 4-34 months), the overall estimated median PFS was 9 months and the estimated median OS was 15 months. Conclusions: This study demonstrated sunitinib is tolerable and effective in advanced/metastatic RCC Egyptian patients and indicates we should further seek second and third lines to increase survival equivalence as reported in the worldwide literature.

Most common metastatic tumors of the thyroid gland are squamous cell carcinoma of head and neck region, adenocarcinoma of breast and lung, malignant melanoma, and renal cell carcinoma of kidney in order of frequency. Metastasis from gastrointestinal tract to the thyroid gland rarely occurs. We experienced a case of fine needle aspiraton cytology of metastatic adenocarcinoma of both thyroid glands from the colon. Cytologic smears showed picket-fence like arrangement of nuclei of carcinoma cells and syncytial type of tissue fragments with acinar pattern on necrotic or mucoid background.

Renal cell carcinoma (RCC) is likely to metastasize to other organs, and is often resistant to conventional chemotherapies. Thymoquinone (TQ), a phytochemical derived from the seeds of Nigella sativa, has been shown to inhibit migration and metastasis in various cancers. In this study, we assessed the effect of TQ on the migratory activity of human RCC Caki-1 cells. We found that treatment with TQ reduced the proteolytic activity of matrix metalloproteinase-9 (MMP-9) in Caki-1 cells. TQ significantly repressed prostaglandin E2 (PGE2) production, its EP2 receptor expression as well as the activation of Akt and p38, the wellknown upstream signal proteins of MMP-9. In addition, treatment with butaprost, a PGE2 agonist, also induced MMP-9 activity and migration/invasion in Caki-1 cells. Moreover, pharmacological inhibitors of PI3K/Akt and p38 remarkably attenuated butaprost-induced Caki-1 cell migration and invasion, implying that activation of PI3K/Akt and p38 is a bridge between the PGE2-EP2 axis and MMP-9-dependent migration and invasion. Taken together, these data suggest that TQ is a promising anti-metastatic drug to treat advanced and metastatic RCC.
