OBJECTIVETo report the MRI features of intracranial metastases of lung cancer.

METHODSA total of 858 patients with history of primary lung cancer suspicious of brain metastases was retrospectively reviewed with MRI.

RESULTS1. Of the 858 patients, 393 (45.8%) had brain metastases on MRI. The primary tumor was lung adenocarcinoma in 117 (29.8%), small cell lung cancer in 110 (28.0%), squamous cell cancer in 52 (13.2%), adenosquamous cancer in 16 (4.1%), large cell carcinoma in 2 (0.5%) and carcinoid in 1 (0.3%). The histopathological types of the primary tumor were unknown in 95 (24.2%). 2. Meningeal metastasis was found in 19 patients with lung cancer. The primary tumor was of adenocarcinoma lung in 6, small cell lung cancer in 5, squamous cell carcinoma in 4 and the remaining 4 were of unknown histopathological type. 3. Edema around the lesion: in 120 cases, there was no obvious edema; the edema was slight in 98 cases, moderate in 70, serious in 86.

CONCLUSIONThe brain metastasis of lung cancer is of common occurrence. MRI with enhancement is very helpful in the establishment of diagnosis.

A 61-year-old man with no history of malignancy presented with a rapidly expanding left periorbital mass, first noticed one month prior to presentation. The mass was firm, and a pus-like discharge drained spontaneously from the center of the lesion. A biopsy was performed, and histopathology confirmed squamous cell carcinoma. Systemic evaluation revealed that the patient had a primary esophageal squamous cell carcinoma with multiple metastases. The prognosis of orbital metastasis is generally poor, and this patient expired after one month of conservative treatment.

OBJECTIVE: To describe computed tomography (CT) features of metastatic gallbladder (GB) tumors (MGTs) from various primary tumors and to determine whether there are differential imaging features of MGTs according to different primary tumors. MATERIALS AND METHODS: Twenty-one patients who had pathologically confirmed MGTs and underwent CT were retrospectively enrolled. Clinical findings including presenting symptoms, type of surgery, and interval between primary and metastatic tumors were recorded. Histologic features of primary tumor and MGTs including depth of invasion were also reviewed. Imaging findings were analyzed for the location and morphology of MGTs, pattern and degree of enhancement, depth of invasion, presence of intact overlying mucosa, and concordance between imaging features of primary and metastatic tumors. Significant differences between the histologies of MGTs and imaging features were determined. RESULTS: The most common primary tumor metastasized to the GB was gastric cancer (n = 8), followed by renal cell carcinoma (n = 4) and hepatocellular carcinoma (n = 3). All MGTs (n = 21) manifested as infiltrative wall thickenings (n = 15) or as polypoid lesions (n = 6) on CT, similar to the features of primary GB cancers. There were significant differences in the morphology of MGTs, enhancement pattern, enhancement degree, and depth of invasion according to the histology of primary tumors (p < 0.05). Metastatic adenocarcinomas of the GB manifested as infiltrative and persistently enhancing wall thickenings, while non-adenocarcinomatous metastases usually manifested as polypoid lesions with early wash-in and wash-out. CONCLUSION: Although CT findings of MGTs are similar to those of primary GB cancer, they are significantly different between the various histologies of primary tumors.

INTRODUCTIONPenile cancer is an uncommon disease affecting only about one in 100,000 men worldwide in a year. The diagnosis of the condition is frequently delayed, and the disease and its treatment frequently result in significant morbidity in patients.

METHODSWe herein describe seven cases of penile tumours: six cases of squamous cell carcinomas and one case of B-cell lymphoma that presented to our hospital's urology department between March 2011 and October 2012. We reviewed the literature to discuss the clinical presentation, natural history and current management of penile cancer.

RESULTSThe patients were followed up for 1-24 months. They were managed according to their disease stage and lymph node status. Four out of seven patients showed disease progression during the follow-up period.

CONCLUSIONThe accurate staging of inguinal nodes in cases of low-risk disease is important to prescribe appropriate surgery for the inguinal nodes. Aggressive management of inguinal and pelvic lymph nodes remains the cornerstone in the treatment of high-risk disease cases.

OBJECTIVETo investigate the clinical characteristics and prognostic factors for patients with stage Ia-IIb cervical cancer with pulmonary metastasis (CCMP).

METHODSClinical information of 106 patients with stage Ia-IIb cervical cancer with lung metastases admitted in the Chinese Academy of Medical Sciences Cancer Hospital from January 1999 to June 2013 was collected. The efficacy of different therapeutic methods for lung metastases was compared and relevant prognostic factors were analyzed.

RESULTSPulmonary metastases were detected in 89 (83.9%) out of a total of 106 patients within 2 years after initial treatment of cervical cancer. The median disease-free interval (DFI) of the 106 patients was 13 months. The median survival after CCMP was 18 months, with 2-year and 5-year survival rates of 37.7% and 7.5%, respectively. Metastases were mainly distributed in the inferior lobe of right lung. The surgical treatment was proven to be clinically effective in both unilateral and bilateral CCMP. The response rate was 60.2% in patients choosing non-operative treatment. The univariate analysis showed that pathological type of cervix carcinoma, low degree of differentiation, scope of pulmonary metastasis and whether CCMP simultaneously accompanied with other parts of recurrence were closely related to the prognosis, while the differentiation of cervical tumor was an independent prognostic factor drawn from multivariate regression analysis.

CONCLUSIONSRegular CT lung screening is recommended for patients with stage Ia-IIb cervical cancer during their follow-up period. Both operative and non-operative treatments are feasible therapeutic methods for CCMP. But surgical resection is strictly restricted to certain operative indications. Ia-IIb stage cervical cancer of low differentiation has poorer prognosis after lung metastasis.
