3.Medical Management of Intraductal Papillary Mucinous Neoplasm.
The Korean Journal of Gastroenterology 2008;52(4):214-219
Intraductal papillary mucinous neoplasm (IPMN) is frequently found recently and is a precancerous lesion. Main duct-type should be resected since it can easily progress to invasive IPMN, whereas branch duct-type (BD) usually remains silent without malignant transformation. BD-IPMN should be resected if it has mural nodule, thick wall or septum, or solid component which are the obvious risk factors for malignancy. If the cyst size of BD-IPMN is more than 3 cm in diameter without obvious risk factors, it can be followed-up regularly or can be treated either with surgical resection or endoscopic ultrasonography (EUS)-guided ethanol lavage. Small BD-IPMN less than 3 cm in size without risk factors can be followed up with sonography, CT scan or EUS annually.

OBJECTIVETo investigate the clinicopathological features, treatment, and prognosis of gastric neuroendocrine carcinoma and gastric carcinoma with neuroendocrine cell differentiation.
METHODSA total of 19 patients were treated for gastric neuroendocrine cancer or gastric cancer with neuroendocrine differentiation in the Beijing Cancer Hospital from January 1997 to December 2008. Clinical data were retrospectively analyzed.
RESULTSFourteen patients had neuroendocrine carcinoma in the gastric cardia (n=9) or gastric body(n=5), and 5 patients had gastric cancer with neuroendocrine differentiation in the gastric cardia(n=2), the antrum(n=2), and the entire stomach(n=1). According to the International Classification of Disease for Oncology(2000), patients were divided into gastric carcinoid type I((n=2, 10.5%), type III( sporadic gastric carcinoid (n=9, 47.4%), small cell carcinoma of the stomach(n=3,15.8%), and gastric cancer with neuroendocrine cell differentiation(n=5, 26.3%). Clinical manifestations were mostly non-specific. Diagnosis was based on pathological and immunohistochemical examination. Eighteen patients underwent surgery including radical subtotal gastrectomy and total gastrectomy, of whom 3 underwent simultaneous resection of the liver metastasis. The remaining one patient with small cell carcinoma of the gastric body received chemotherapy alone because of unresectable liver metastasis. The survival rate was 73.7% at 1 year and 38.6% at 3 years.
CONCLUSIONSGastric neuroendocrine carcinoma usually develops in the cardia and body of the stomach. Gastric carcinoma with neuroendocrine cell differentiation can occur in any locations of the stomach. Immunohistochemistry is important to the diagnosis. Radical resection is the main treatment.

OBJECTIVES:
To investigate the clinical and pathological features of patients with unilateral sinonasal disease (USD).
METHODS:
A retrospective analysis was completed on 376 adult patients with USD from January 2015 to December 2016. Their presenting symptoms, nasal endoscope, CT scanning, and pathology were analyzed respectively.
RESULTS:
Among the 267 (71.01%) patients with inflammatory disease, there were 4 pathological types. And there were 8 pathological types in 60 (15.96%) patients with benign tumor. Of the 49 patients with malignant tumor, there were 15 pathological types which included squamous carcinoma, malignant melanoma, and lymphoma, as well as myoepithelial carcinoma and Mesodermal mesoderm. The onset age of inflammation group was younger than that of benign (<0.05) or malignant tumor groups (<0.05). The misdiagnosis rate was 8.33% in benign tumor (5/60), and 10.20% in malignant tumor (5/49). Nasal polyps was the most common misdiagnosis in the groups of benign and malignant tumor.
CONCLUSIONS
The pathology of adult patients with USD is complicated, and no specific clinical feature was found for distinguishing between benign and malignant lesions. The tumor took a quite proportion in adult patients with USD. Therefore, careful consideration should be taken before diagnosing patients with USD in order to reduce misdiagnosis rate.

7.Clinical analysis of primary squamous cell carcinoma of the breast.
Chinese Journal of Surgery 2003;41(3):183-185
OBJECTIVETo study the clinicopathological features of primary squamous cell carcinoma (SCC) of breast and the diagnosis and treatment of the disease.
METHODSThe clinical, operative and pathological data from 7 cases of SCC of breast were retrospectively analysed.
RESULTSFive patients complained of painless mass and two of them were accompanied with local pain. All patients were diagnosed as having SCC by fine-needle aspiration before operation. Two patients underwent modified radical mastectomy, and the others received radical mastectomy. Pathological examination showed primary squamous cell carcinoma of the breast with metastasis to axlliary lymph nodes in one patient. Follow-up of four patients revealed that two patients are living well and two patients died. Three patients lost to follow up.
CONCLUSIONThe diagnosis of primary squamous cell carcinoma of the breast is dependent on pathological results. Radical mastectomy including modified radical mastectomy is most effective in the treatment of mammary SCC. Postoperative chemotherapy and radiation are necessary auxiliary therapy.

In recent years, series of driver genes, such as EGFR, KRAS/NRAS, BRAF, PIK3CA, ALK and ROS1 and so on, have been found in non-small cell lung cancer (NSCLC) one after another with the development of molecular detecting technology. Targeted drugs bring benefits for these NSCLC patients with driver gene variations. However, some NSCLC did not have any known driver gene variations; we called it pan-negative lung cancer. In this paper, we summarize the concept, clinical pathological characteristics, the epidemiological characteristics, treatment and prognosis of pan-negative NSCLC.

Dermatomyositis (DM) is an uncommon inflammatory myopathy with characteristic rash accompanying, or more often preceding, muscle weakness. There is a well-recognized association between DM and several cancers, such as ovarian cancer, breast cancer, melanoma, colon cancer, and non-Hodgkin lymphoma. We report the first case of cancer of unknown primary site associated with DM. A 62-yr-old woman presented to us with both shoulder painful swelling and facial edema. She was diagnosed previously as cancer of unknown primary site, histologically confirmed with squamous cell carcinoma in a pelvic mass. For the following days, she complained of erythematous face followed by progressive weakness of the proximal muscles of upper and lower limbs. The laboratory tests showed an increased muscle enzyme and acute phase reactants. The electromyogram showed the typical findings of DM. After the treatment with high dose steroid and methotrexate, the proximal motor weakness improved, and she received palliative radiation therapy.
