OBJECTIVETo investigate clinicopathological features and prognostic factors of appendiceal neuroendocrine neoplasms(a-NEN).

METHODSClinical data of 20 patients diagnosed with a-NEN at Zhongshan Hospital of Fudan University between January 2000 and December 2016 were retrospectively analyzed. Pathological diagnosis was based on the WHO classification criteria of digestive system tumors (2010 edition). Based on the mitotic count and Ki-67 index, a-NENs were divided into grade 1 neuroendocrine tumor (NET G1), grade 2(G2) NET G2) and grade 3 (neuroendocrine carcinoma, NEC). Some special types of a-NEN (e.g. goblet cell carcinoid) and mixed adenoneuroendocrine neoplasms were classified as mixed adenoneuroendocrine carcinoma (MANEC). Follow-up was conducted by telephone or return visits. Univariate analysis was carried out using the Kaplan-Meier method, and the log-rank test was used to draw survival curves.

RESULTSOf 20 patients, 14 were male and 6 were female with median age of 54 years. Seventeen cases presented acute right lower quadrant abdominal pain, 1 chronic right lower quadrant abdominal pain, 1 persistent abdominal discomfort with outburst whole abdominal pain and 1 was found during body check without symptoms. Twenty cases comprised 8 G1 patients, 4 G2 patients, 3 G3 patients, and 5 MANEC patients. When diagnosed, there was 1 patient with liver metastasis, 1 patient with abdominal and pelvic metastases, and 2 patients with postoperative pathological findings of lymph node metastasis. Six patients underwent appendectomy, 12 underwent right hemicolectomy, 1 underwent right hemicolectomy plus small intestine resection, and 1 underwent partial hepatectomy plus right hemicolectomy. The follow-up time was 7-187 months(average, 36 months). The total 1- and 3-year survival rates were 94.7% and 60.2%, respectively. Univariate analysis showed that age >50 years (χ=7.036, P=0.008), pathology grade as MANEC (χ=5.297, P=0.021), and metastasis (χ=6.558, P=0.010) indicated lower 5-year survival rate.

CONCLUSIONSMost a-NEN patients have no typical symptoms, and the main complaint at consultation is acute right lower quadrant abdominal pain. Prognosis is poor for patients with age >50 years, MANEC pathology grade and metastasis.

PURPOSE: Inflammation-based prognostic scores including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR) are associated with oncologic outcomes in diverse malignancies. We evaluated the predictive value of pretreatment prognostic scores in differentiating nonmuscle invasive (NMIBC) and muscle invasive bladder cancer (MIBC). MATERIALS AND METHODS: Consecutive transurethral resection of bladder tumour (TURBT) cases from January 2011 to December 2013 were analysed retrospectively. Patient demographics, tumour characteristics and prognostic scores results were recorded. Receiver operating characteristics curves were used to determine prognostic score cutoffs. Univariate and multivariate binomial logistic regression analysis was performed to evaluate the association between variables and MIBC. RESULTS: A total of 226 patients were included, with 175 and 51 having NMIBC (stages Ta and T1) and MIBC (stage T2+) groups, respectively. Median age was 75 years and 174 patients were male. The NLR cutoff was 3.89 and had the greatest area under the curve (AUC) of 0.710, followed by LMR (cutoff<1.7; AUC, 0.650) and PLR (cutoff>218; AUC, 0.642). Full blood count samples were taken a median of 12 days prior to TURBT surgery. Multivariate logistic regression analysis identified tumour grade G3 (odds ration [OR], 32.848; 95% confidence interval [CI], 9.818-109.902; p=0.000), tumour size> or =3 cm (OR, 3.353; 95% CI, 1.347-8.345; p=0.009) and NLR> or =3.89 (OR, 8.244; 95% CI, 2.488-27.316; p=0.001) as independent predictors of MIBC. CONCLUSIONS: NLR may provide a simple, cost-effective and easily measured marker for MIBC. It can be performed at the time of diagnostic flexible cystoscopy, thereby assisting in the planning of further treatment.

PURPOSE: It is well known that testicular germ cell tumors arise with increased frequency in patients with cryptorchidism. In addition, intratubular germ cell neoplasia (ITGCN) is a precursor lesion to testicular germ cell tumor. Approximately 50% of patients with ITGCN will develop an invasive of testicular germ cell tumors within 5 years. Therefore, we evaluated that the incidence of ITGCN in postpubertal cryptorchidism. MATERIALS AND METHODS: Between January 2002 and August 2012, orchiectomy specimens from 31 postpubertalpatients (aged 12 or over) with cryptorchid testis were reviewed. The specimens were evaluated for ITGCN using immunohistochemical stains of placental-like alkaline phosphatase and Oct 3/4 with routine hematoxylin-eosin stain. Additionally, the degree of spermatogenesis was assessed using the Johnsen score. RESULTS: Mean age was 34 years (range, 17 to 74 years) at surgery. All patients were diagnosed as unilateral cryptorchidism. One patient (3.2%) of 20-year-old had ITGCN in surgical specimen with all positive markers. Histological assessment of spermatogenesis showed that mean Johnsen score was 3.42 (range, 1 to 9). Majority of patients (27 of 31) presented impaired spermatogenesis with low Johnsen score lesser than 5. CONCLUSIONS: Considering the risk of malignancy and low spermatogenesis, we should perform immunohistochemical stains and discuss preventative orchiectomy for the postpubertal cryptorchidism.

We report the rare case of a patient with advanced renal cell carcinoma (RCC) who initially presented to the hospital with symptoms of cardiac failure. Preoperative cardiac studies did not reveal any underlying ischemia. After resection of a large 14-cm left renal tumor, cardiac function was noted to improve dramatically. We discuss this case of concomitant RCC and nonischemic cardiomyopathy.

OBJECTIVE: To evaluate the prognostic implication of human papillomavirus (HPV) viral load in cervical cancer patients who underwent radical hysterectomy. METHODS: We conducted a retrospective review of patients with stage IA2 through stage IIIA cervical carcinoma who underwent radical hysterectomy at Sun Yat-sen University Cancer Center between January 2005 and December 2009. Patients who had undergone preoperative hybrid capture 2 testing to detect HPV DNA were included. A total of 346 patients positive for HPV DNA were enrolled and stratified into two groups according to the median HPV viral load. RESULTS: HPV viral load was significantly correlated with lymphovascular space invasion (p=0.026) and deep stromal invasion (p=0.024). However, other factors, such as age, stage, histologic grade, histologic type, lymph node metastasis, and tumor size, were not significantly associated with viral load. Low HPV viral load was correlated with poor disease-free survival in univariate analysis (p=0.037) and multivariate analysis (p=0.027). There was no significant difference in overall survival with regard to initial HPV viral load. CONCLUSION: Low initial HPV viral load may be a poor prognostic factor for cervical cancer patients who have undergone radical hysterectomy.

PURPOSE: To report clinical characteristics of thyroid-associated ophthalmopathy (TAO) in patients who previously underwent total thyroidectomy for thyroid cancer or a benign mass of the thyroid. MATERIALS AND METHODS: Of the patients who were diagnosed with TAO from March 2008 to March 2012, we performed a retrospective chart review on those who had undergone total thyroidectomy for thyroid cancer or a benign mass of the thyroid before the occurrence of ophthalmopathy. RESULTS: Of the 206 patients diagnosed with TAO, seven (3.4%) met the inclusion criteria. The mean age of the subjects was 47.4 years, and all were female. Six patients were diagnosed with papillary thyroid cancer, and one was diagnosed with a benign mass. The duration between total thyroidectomy and onset of TAO ranged from 3-120 months (median 48 months). Ophthalmic manifestations varied among cases. Except for the patient who was diagnosed with a benign mass, all patients showed hyperthyroid status and were under Synthroid hormone treatment at the time of TAO development. Five of these six patients had positive levels of thyroid-stimulating hormone (TSH) receptor autoantibodies. CONCLUSION: TAO rarely develops after total thyroidectomy, and the mechanism of TAO occurrence is unclear. However, most patients showed abnormalities in thyroid function and TSH receptor autoantibodies.

OBJECTIVETo evaluate and compare the value of stair climbing tests and conventional pulmonary function tests in the prediction of postoperative cardiopulmonary complications in non-small cell lung cancer patients underwent surgery.

METHODSFrom April 1, 2010 to Jan. 30, 2012, a total of 162 patients with thoracic carcinoma underwent stair climbing test (SCT) and conventional pulmonary function tests (PFT) preoperatively. The correlation of postoperative cardiopulmonary complications with the SCT and PFT parameters were analyzed retrospectively using chi-square test, independent sample t test and binary logistic regression analysis.

RESULTSOf the 162 patients, 19 without operation were excluded, due to an advanced stage (9 cases), poor cardiopulmonary function (5 cases), rejecting operation (4 cases) and exploration alone (1 case). 143 cases were eligible and evaluated eventually. Forty-one of the 143 patients (28.7%) had postoperative cardiopulmonary complications, but no death occurred. The patients were stratified into groups based on the time of stair climbing 5 stories (18.36 m, t, <92 s, ≥ 92 s). Exercise oxygen desaturation (EOD) during the stair climbing test (<5%, ≥ 5%) and the difference between the pulse at resting state and the pulse at end of stair climbing test (ΔP, <55 beats/min, ≥ 55 beats/min), respectively. The rate of postoperative cardiopulmonary complications was significantly higher in the group with t ≥ 92 s, EOD ≥ 5% and ΔP < 55 beats/min (38.5%, 42.0% and 35.1%, respectively) than that in the group with t<92 s, EOD<5% and ΔP ≥ 55 beats/min (16.9%, 21.5% and 18.2%, respectively). Binary logistic regression analysis showed that postoperative cardiopulmonary complications were independently correlated with EOD and lung function which did not meet the requirement of the lung resection operation mode.

CONCLUSIONSA symptom-limited stair climbing test is a safe, simple and low-cost method to evaluate the cardiopulmonary function preoperatively. It can predict the occurrence of postoperative cardiopulmonary complications in non-small cell lung cancer patients. Conventional pulmonary function tests and stair-climbing test can be recommended to be routinely performed in all patients with non-small cell lung cancer before thoracic surgery.

OBJECTIVETo study the clinicopathologic characteristics of parathyroid carcinoma (PTC).

METHODSEleven cases of PTC encountered during the period from 1994 to 2012 were enrolled into the study. Forty cases of parathyroid adenoma (PA) were also retrieved for comparison. The clinical manifestations, laboratory results and pathologic features were analyzed, with literature review.

RESULTSThe main clinical manifestations of PTC included neck mass (11/11), hypercalcemia (11/11) and hyperparathyroidism (11/11). Most patients also had osteoporosis (10/11). In contrast, PA often manifested as hypercalcemia (40/40) and hyperparathyroidism (40/40). Histologic examination of PTC showed that the tumor cells contained clear to eosinophilic cytoplasm and separated by dense bands of fibrosis. The tumor mass was surrounded by thick fibrous capsule. Foci of capsular invasion and vascular permeation were identified at the tumor periphery in all cases. Cellular atypia was not conspicuous but mitotic figures and coagulative necrosis were easily identified. On the other hand, PA were composed of tumor cells with clear to eosinophilic cytoplasm, forming glands, trabeculae or nests. Most of them (35/40) had intact fibrous capsule. Mitotic figures were rarely encountered and tumor necrosis was absent. Immunohistochemical study showed that the tumor cells in PTC were positive for CK19 (11/11), chromogranin A (9/11), synaptophysin (7/11) and parathyroid hormone (11/11). They were negative for thyroglobulin, TTF-1 and calcitonin. The Ki-67 index was less than 10% (range = 2% to 9%). In contrast, the tumor cells in PA were positive (40/40) for CK19, chromogranin A, synaptophysin and parathyroid hormone. They were negative for thyroglobulin, TTF-1 and calcitonin. The Ki-67 index was less than 3%. Follow up-data were available in 9 cases of PTC (duration of follow up = 11 months to 224 months) and 7 of the patients were still alive. Follow up of all PA cases showed no evidence of recurrence.

CONCLUSIONSPTC is a rare malignant endocrine tumor presenting as neck mass. Histologic features suggestive of malignant behavior include presence of coagulative tumor necrosis and capsular/vascular invasion. It needs to be distinguished from other entities such as parathyroid adenoma, papillary thyroid carcinoma and medullary thyroid carcinoma.

OBJECTIVETo study the clinicopathologic features, histologic diagnosis and differential diagnosis of primary mucosal tuberculosis (TB) in the head and neck region.

METHODSForty-seven cases of primary mucosal TB of the head and neck region were studied by hematoxylin-eosin and Ziehl-Neelsen stains. The clinical and pathologic features were analyzed with review of the literature.

RESULTSThe patients included 26 male and 21 female, with mean age 47.1 years (range 14-84 years). There were three sinonasal TB, 19 nasopharyngeal TB, two oropharyngeal TB, 18 laryngeal TB, four middle ear TB, one salivary gland TB and one laryngeal TB complicating laryngeal cancer. The initial symptoms were nasal obstruction, mucopurulent rhinorrhea, epistaxis, snoring, hoarseness, dysphagia, odynophagia, serous otitis, hearing loss, tinnitus, and otalgia. Physical examination result was variable, from an apparently normal mucosa, to an evident mass, or a mucosa with an adenotic or swollen appearance, ulcers, leukoplakic areas, and various combinations thereof. CT and MRI findings included diffuse thickening, a soft-tissue mass, calcification within the mass and bone destruction resembling malignancy. Histologic examination showed granulomas with a central necrotic focus surrounded by epithelioid histiocytes and multinucleated Langhan's giant cells. Acid-fast bacilli were difficult to demonstrate but found in 13/45 cases. Follow-up data were available in 42 patients.

CONCLUSIONSPrimary TB arising in the head and neck mucosa is rare. It may mimic or co-exist with other conditions. The characteristic histopathology is a granuloma with central caseous necrosis and Langhans'giant cells. Identification of acid-fast bacilli and bacteriologic culture confirm the diagnosis of mycobacterial disease.
