Unlike other non-gynecologic solid tumors, such as breast cancer, lung cancer, metastasis to bone from endometrial carcinoma is rare, metastasis to extremity is extremely rare. We report a 51-year-old multiparous woman with FIGO Stage IVb Grade 2 endometrial adenocarcinoma which metastasized to left lower extremity bone. She received an amputation of left lower extremity below the knees, and a total abdominal hysterectomy and bilateral salpingo-oophorectomy, and followed by systemic chemotherapy, radiation therapy to the pelvis and progestational agent. She had a complete response to above treatments, and disease-free survival for 10 months. After recurrence, she received chemotherapy, radiotherapy and progestational agent once again. She had lived 56 months and is still alive by the time of report. Metastasis of endometrial carcinoma to extremity bone can rarely occur and should be considered when the patient with endometrial carcinoma complained of unexplained pain and swelling associated with extremity bone.

Follicular carcinoma of the thyroid rarely manifests itself as a distant metastatic lesion, and, when present, is usually found in flat bones. A soft tissue metastasis is extremely rare, and synchronous metastases to the bone and soft tissue is not reported in the literature so far. We report such a case of a 42-yr-old male, who presented with a goiter, scalp and forearm soft tissue swellings, and, fine needle aspiration cytology of all these swellings revealed a follicular neoplasm. A wide excision of the forearm swelling was carried out and the histopathology was consistent with features of metastatic follicular carcinoma of the thyroid. The main stay of treatment is surgical resection of the primary tumor. The various modalities of treatment of metastasis is discussed with a review of literature.

Mucinous tubular and spindle cell carcinoma (MTSCC) is a rare sub-type of renal cell carcinoma (RCC). It has been considered to be a kind of "indolent" tumor with low-grade fashion, weak invasive capacity and relatively favorable prognosis. However, in the current case, a 3.7 cm×2.8 cm spherical mass with contrast enhancement was found in the left kidney incidentally by computed tomography (CT) in a 60-year-old male patient. A lesion in the right humerus (2.1 cm×1.6 cm×3.1 cm) was found at the same time without any symptoms or sign of pathological fracture by magnetic resonance (MR) imaging. Further positron emission tomography (PET)/CT scan which was ordered immediately after admission suggested multiple bone destruction including skull, pelvis, sternum, right humerus and femur, left scapula, multiple vertebrae and libs. Pathological examination after radical nephrectomy and palliative resection with internal fixation of the lesion in the right humerus indicated that both renal (3.0 cm×3.0 cm×2.5 cm) and bone lesions were MTSCC with the features of high-grade ovoid epithelioid cells, cord-like spindle cells and mucinous matrix under light microscope. The diagnosis of renal MTSCC concurrent with multiple bone metastasis was made. This case report suggested the necessity of general evaluation, especially bone scan for possible distant metastasis, as MTSCC might present unexpected advanced behaviors without any orthopedic symptoms. The behavior of bone metastasis might be associated with male and elderly age. MTSCC has similar enhancement features to papillary RCC on CT scan. As results, attentions are needed to differentiate MTSCC from papillary RCC as they both tend to show lesser enhancement degrees than cortex. Rather than exhibiting a dedifferentiating appearance, the pathological characteristics of bone metastasis lesion were close to those of primary renal lesion. The reason of distant metastasis to the bone remained unclear, negative expression of cytokeratin (CK) 7 might be attributed to. Though immunotherapy, chemotherapy and target therapy could all be methods for systematic therapies, procedures to remove renal lesions and prevent skeletal related events are still highly recommended.

OBJECTIVETo investigate the risk factors of metachronous bone metastasis after radical resection of colorectal cancer within 5 years.

METHODSClinical data of 1 749 patients with colorectal cancer, of whom 50(2.8%) patients developed metastasis to bone after operation, in the Department of Colorectal Surgery, Changhai Hospital of The Second Military Medical University from January 2001 to December 2010 were analyzed retrospectively. Univariate and multivariate analysis were performed to find the risk factors of metachronous bone metastasis from colorectal cancer using Chi square test and Logistic regression, respectively.

RESULTSOf 50 colorectal cancer cases with bone metastasis, 29 were male and 21 were female. The age was ≥ 60 years old in 28 cases. Tumors of 36 cases were located in the rectum and of 14 cases located in the colon. Pathology examination showed 43 cases were adenocarcinomas, 7 cases were mucinous adenocarcinoma. Forty-two cases had T3-4 stage lesions, 30 cases had lymph node metastasis, 14 cases had pulmonary metastasis, and 5 cases had liver metastasis. Univariate Chi square test indicated that factors associated with the metachronous bone metastasis of colorectal cancer within 5 years were tumor site (χ=4.932, P=0.026), preoperative carbohydrate antigen 199 (CA199) level (χ=4.266, P=0.039), lymph node metastasis (χ=13.054, P=0.000) and pulmonary metastasis(χ=35.524, P=0.000). The incidence of bone metastasis in patients with rectal cancer (3.6%, 36/991) was higher compared to those with colon cancer (1.8%, 14/758). The incidence of bone metastasis in patients with higher(> 37 kU/L) preoperative serum CA199 level (4.9%, 12/245) was higher compared to those with lower serum CA199 level (2.5%, 38/1504). The incidence of bone metastasis in patients with lymph node metastasis(4.8%,30/627) and pulmonary metastasis (11.6%, 14/121) was significantly higher compared to those without lymph node metastasis (1.8%, 20/1122) and pulmonary metastasis(2.2%, 36/1628), respectively. Logistic multivariate analysis showed that rectal cancer(OR:0.508, 95%CI:0.268 to 0.963, P=0.038), lymph node metastasis (OR:2.291, 95%CI:1.273 to 4.122, P=0.006) and metachronous pulmonary metastasis(OR:4.796, 95%CI:2.473 to 9.301, P=0.000) were the independent risk factors of metachronous bone metastasis of colorectal cancer within 5 years.

CONCLUSIONPatients with rectal cancer, lymph node metastasis and metachronous pulmonary metastasis are high risk groups of metachronous bone metastasis after radical resection of colorectal cancer within 5 years.

OBJECTIVETo improve the life quality of cancer patients with metastasis to long bone and to select suitable surgical treatment.

METHODSFifty two patients with metastasis 27 men and 25 women, were treated from 1990 to 1999. Their average age was 56.8 years (33 - 74). In 16 patients with multiple lesions, underwent surgery at bone shaft (29 patients) and bone epiphysis (26). Thirty patients were treated for pathologic fracture and the rest for impending fracture. Operations included limb-salvage (51 patients) and amputation (4) Limb salvage consisted of intralesional curettage (3 patients), intramedullary nailing reconstruction (29), endoprosthesis (18), and temporary spacer (1). 21 patients accepted postoperative chemotherapy or radiotherapy.

RESULTSFollow-up of 52 patients for a mean of 28.2 months (2 - 122 months) showed pain relief (41 patients), (75%) and full or part weight-bearing stability (36) 69%. Local tumor recurrence occurred in 11 patients.

CONCLUSIONSSurgical treatment can effectively improve the life quality of patients with metastasis to long bone. The metastatic lesions should be resected with wide or radical margin for the patients with kidney, breast, prostate and thyroid cancer.

OBJECTIVETo retrospectively review the experience with different surgical procedures for periacetabular metastasis.

METHODSThe data of 43 patients with periacetabular metastasis between July 2000 and July 2007 was reviewed. There were 21 patients with primary malignant tumors at the beginning, and 10 patients diagnosed metastasis by preoperative biopsy. The other 12 patients presented skeletal involved as initial manifestations of metastasis prior to the pathological diagnosis of the primary tumor. Twelve patients had solitary metastasis, and the others had multiple bone metastasis. The surgical procedure included curettage (35 cases) and en-blot excision (8 cases). The techniques of reconstruction of acetabular defect included total hip replacement (THR) with cemented components or titanium acetabular reconstruction cup (12 cases), THR with partial pelvis replacement with Candal Hook (16 cases), THR with Steinmann pins and cement augmented or titanium cup reconstruction (7 cases), and modular hemipelvic prosthesis reconstruction (8 cases).

RESULTSAll the patients received successful operations. The average score for preoperative pain of 7.2 was assessed. Forty-one patients (95.4%) were evaluated for relief of pain and resumption of walking, and the pain score improved to 3.5 after surgery. The average functional score was 24.5 postoperatively. Six of 32 patients had local recurrence. Fourteen patients died of diseases. The average blood loss during the operation was 1600 ml in 43 patients and the bleeding exceeded 3000 ml was in 3 patients with renal carcinomas. Major complications included two superficial wound infections, one multiple organ failure and two dislocations.

CONCLUSIONSAlthough surgery will not typically cure patients of their metastatic disease, surgery that is well planned and well executed can help many people by relieving their suffering and improving their quality of life.
