Metastatic renal cell carcinoma (RCC) in the nose and paranasal sinuses is very rare. We report an unusual case of metastatic RCC that presented as recurrent epistaxis ten years after curative nephrectomy. The purpose of this report is to draw the attention of clinicians to the possibility of metastatic RCC in patients with recurrent epistaxis and nasal mass. We also discuss treatment options and review the relevant literature.

Multiple bone metastases are common manifestation of many malignant tumors such as lung cancer, breast cancer, prostate cancer and renal cell carcinoma. Bone metastasis is secondary cancer in the bone, and it can lead to bone pain, fracture, and instability of the weight bearing bones, all of which may profoundly reduce physical activity and life quality. Treatment for bone metastasis is determined by multiple factors including pathology, performance status, involved site, and neurologic status. Treatment strategies for bone metastasis are analgesics, surgery, chemotherapy and radiotherapy. External beam radiotherapy has traditionally been an effective palliative treatment for localized painful bone metastasis. However, in some cases such as multiple bone metastases, especially osteoblastic bone metastasis originated from breast or prostate cancer, the radiopharmaceutical therapy using (89)Sr, (186)Re, (188)Re, (153)Sm and (117m)Sn are also useful treatment option because of administrative simplicity (injection), few side effects, low risk of radiation exposure and high response rate. This article offers a concise explanation of the radiopharmaceutical therapy for multiple bone metastases.

BACKGROUNDSunitinib has been proved an effective new option for treatment of metastatic renal cell carcinoma (mRCC). Analysis of clinical data of 22 patients, who were exposed to sunitinib for at least 1 year, was conducted to evaluate the long-term efficacy and safety of sunitinib for the treatment of mRCC.

METHODSA total of 54 patients with mRCC were treated with sunitinib malate, 50 mg/d orally, on a 4-weeks-on and 2-weeks-off dosing schedule in Peking University First Hospital. Treatment continued until disease progression, unacceptable adverse events (AEs), or death. Among them, 22 patients continued treatment for at least 1 year. The clinical data of these 22 patients were prospectively collected for analysis. AEs were assessed according to the National Cancer Institute Common Terminology Criteria for Adverse Events, Version 3.0. Tumor response was evaluated in accordance with the Response Evaluation Criteria in Solid Tumors.

RESULTSMedian progression-free survival was 19.5 months until last follow-up. The best efficacy results achieved were complete response, partial response, and stable disease for 2, 9, and 11 patients, respectively. Objective response rate was 50%. The most common AEs were hand-foot syndrome (95%) and hypertension (91%). Other common AEs were thyroid-stimulating hormone elevation (82%), platelet decrease (77%), and loss of appetite (77%). Only one patient withdrew from treatment for cardiac infarction. Another nine patients experienced dose modifications or short-term suspensions.

CONCLUSIONLong-term exposure to sunitinib malate showed encouraging efficacy in the treatment of mRCC. At the same time, the tolerability was good.

Pituitary metastasis from renal cell carcinoma is rare and has never been reported for renal cell carcinoma primarily treated with sorafenib. Herein, we present a case of an advanced clear-cell renal cell carcinoma in which pituitary metastasis progressed but extracerebral metastases showed partial response to sorafenib treatment.

Unusual sites of metastases are recognized in patients with renal cell carcinoma (RCC). However, the prognostic implications of these sites are not well understood. We used the Memorial Sloan-Kettering Cancer Center (MSKCC) risk classification for metastatic RCC to evaluate 912 consecutive patients with RCC managed at the Singapore General Hospital between 1990 and 2009. Among these patients, 301 had metastases either at diagnosis or during the course of illness. Nasal metastases, all arising from clear cell RCC, were identified histologically in 4 patients (1.3% of those with metastasis). All 4 patients were classified as MSKCC poor prognosis by current risk criteria. Nasal metastases were significantly associated with lung and bone metastases. The frequency of nasal metastases in patients with metastatic RCC is about 1%, occurring predominantly in patients with clear cell RCC. Nasal metastases are associated with poor prognosis as estimated by the MSKCC risk classification, with attendant implications for selection of targeted therapy, and are usually associated with multi-organ dissemination, including concurrent lung and bone involvement.

OBJECTIVETo study the morphologic features, immunophenotypes, differential diagnoses and prognosis of histiocytic sarcoma (HS).

METHODSThe clinical and pathologic findings of 6 cases of HS were reviewed. Immunohistochemical assay (Elivision staining) was also performed. Follow-up information was available in 4 patients.

RESULTSThere were altogether 3 males and 3 females. The age of patients ranged from 12 to 81 years old (median = 54.6 years). The sites of involvement included lymph node (number = 2 cases) and skin or soft tissue (number = 4 cases). The tumor was composed of sheets of large epithelioid cells with abundant eosinophilic cytoplasm, oval to irregular nuclei, vesicular chromatin and large nucleoli. Binucleated form was not uncommon. Two of the cases showed increased pleomorphism with multinucleated tumor giant cell formation. Focal cytoplasmic with foamy appearance was identified in 3 cases. One case demonstrated foci of spindly sarcomatoid appearance. Hemophagocytosis was identified in 2 cases. Mitotic figures were readily identified. The tumor cells were often accompanied by various numbers of inflammatory cells. Immunohistochemical study showed that all cases were diffusely positive for leukocyte common antigen, CD4, CD68 and CD163. Four of the 5 cases studied also expressed lysozyme. Amongst the 4 patients with follow-up information available, 3 died of the disease at 6 to 11 months interval after diagnosis. One patient, whose lesion was localized at the skin and soft tissue, survived for 3 years, with no evidence of tumor recurrence.

CONCLUSIONSAccurate diagnosis of the HS is based on the combination of morphologic examination and immunohistochemical assay. HS often presents with clinically advanced disease and pursues an aggressive clinical course, with a poor response to therapy. However, a subset of cases presenting with clinically localized lesion may carry a relatively favorable long-term outcome.

OBJECTIVEPancreatic metastasis from renal cell carcinoma (RCC) is a rare event and has not been reported in our country. We report a series of 3 patients with metastatic RCC to the pancreas after radical nephrectomy at our institution. The published reports in the literature were reviewed, and the diagnosis, treatment as well as prognosis of this rare event were discussed.

METHODSThe data of 3 RCC patients with metastasis to the pancreas were reviewed retrospectively, including radical nephrectomy, metastatic interval, the second and third surgical removal. Survival of the three patients was analyzed and the reports in the literature were compared as well.

RESULTSThe average interval from radical nephrectectomy to the comfirmed pancreatic metastasis was 6.6 years (range, 1.2 to 12 years). The pathological stage revealed T2N0M0 (n = 2) or T3N0M0 (n = 1), with right-sided tumor in 2 patients and left side in 1. One patient was asymptomatic, while the other two cases were symptomatic at presentation, including upper abdominal pain, weight loss, slight xanthochromia of the skin and titillation, clay stool (n = 1); irregular fever, weight loss and jaundice (n = 1). All pancreatic metastases were hypervascular on arterial stage of CT imaging. One patient had only a solitary pancreatic metastasis (n = 1), the another showed two metastatic lesions (n = 1), the third one had multiple lesions (n = 1). Surgical removal was accomplished in 2 patients: including pylorus-preserving pancreaticoduodenectomy in one, and pylorus-preserving pancreaticoduodenectomy together with partial tail resection in another one. The third one only received interventional therapy due to widespread extrapancreatic metastasis, and died of disseminated disease 11 months after the therapy. One of the above two surgically treated patients underwent the second removal due to local recurrence 2.5 years after the first removal of pancreatic metastasis. These two patients were still alive after follow-up of 8.6 years and 16.1 years, respectively.

CONCLUSIONRenal cell carcinoma is an unpredictable tumor that may demonstrate very delayed metastasis even from early-stage of the disease. The pancreas is a rare site of metastasis from renal cell carcinoma. We advocate careful long-term follow-up of patients with a history of RCC. Aggressive surgical management of pancreatic metastatic lesions may provide a chance of long-term survival.
