Primary mediastinal non-seminomatous germ cell tumors (PMNSGCT) are rare but life-threatening thoracic cancers. We report our experience from eight patients with peri-treatment adverse events. By analyzing changes in tumor extent, serum tumor markers, and pathologies between diagnosis and transfer, those events could be attributed to postbiopsy respiratory insufficiency, growing teratoma syndrome, secondary histiocytic malignancy, and PMNSGCT progression.

We validated an 18-gene classifier (GC) initially developed to predict local/regional recurrence after mastectomy in estimating distant metastasis risk. The 18-gene scoring algorithm defines scores as: <21, low risk; ≥21, high risk. Six hundred eighty-three patients with primary operable breast cancer and fresh frozen tumor tissues available were included.

Mediastinal nonseminomatous germ cell tumor (MNSGCT)-associated histiocytic proliferations are rare and rapidly fatal disorders. Standard treatment modalities have yet to be established.We report a case of MNSGCT-associated hemophagocytic syndrome that evolved into malignant histiocytosis/disseminated histiocytic sarcoma (MH/HS), which was initially treated with intravenous immunoglobulin, corticosteroids, and cyclosporine.

Background/aim: Estrogen is thought to play an important role in lung cancer carcinogenesis and progression. The incidence and survival of second primary lung cancer among breast cancer patients with and without anti-estrogen therapy were evaluated.

Patients And Methods: All women diagnosed with breast cancer and treated at the Sun Yat-Sen Cancer Center between January 2000 and December 2009 were included and followed-up for occurrence and/or death from lung cancer until December 2011.

Purpose: The objective of this study was to differentiate the magnetic resonance (MR) imaging appearance of benign peripheral nerve sheath tumors (PNSTs) from that of malignant PNSTs.

Materials And Methods: Twenty-six patients who underwent MR imaging and had a histologic diagnosis of benign (schwannoma, n=16; neurofibroma, n=1) or malignant (n=9) PNST were retrospectively reviewed. The size, location, shape, margin, and signal intensities of the tumors on precontrast and gadolinium-enhanced MR imaging were analyzed.

Objective: To investigate the magnetic resonance imaging (MRI) features of well-differentiated hepatocellular carcinoma (HCC).

Methods: We reviewed the MRI of 32 patients with 33 pathologically confirmed well-differentiated HCC. The MRI protocol included T2-weighted imaging with and without fat saturation, dual-phase T1-weighted imaging, and gadolinium-enhanced dynamic study.

Angiomatoid fibrous histiocytoma is a rare soft tissue tumor of low-grade malignancy. We present the case of a 32-year-old man who complained of soreness and numbness over his left arm and hand over the previous 2 months and of having a palpable mass over his left upper back for 4 years. Magnetic resonance imaging (MRI) showed an intramuscular soft tissue mass in the left scapular region.

A case of spontaneous regression of hepatocellular carcinoma is reported and compared with the reports published in the English literature. Spontaneous regression of a histologically proven hepatocellular carcinoma was observed in a 42-year-old male patient with chronic hepatitis B. The patient refused to receive any medical therapy.

Background And Purpose: 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) is a relatively new modality in the follow-up of patients with differentiated thyroid cancer (DTC) who have undergone total thyroidectomy and postoperative radioiodine therapy. The aim of this study was to assess the diagnostic value of FDG-PET, comparing it with 131I whole-body scan (WBS) and 201Tl WBS.

Methods: Fifteen selected patients with local invasive and/or aggressive DTC were included in this study.
