2.Sentinel lymph notes in female reproductive tract cancer.
Acta Academiae Medicinae Sinicae 2003;25(4):377-380
To reduce extensive radical procedures and decrease morbidity in gynecologic malignancies, much effort is being focused on implementing less aggressive interventions. Two different approaches such as lymphatic mapping and lymphoscintigraphy are currently used to identify sentinel lymph nodes. In vulvar and cervical carcinomas, metastatic spread of disease commonly follows stepwise progressive drainage. Thus, sentinel lymph node identification may significantly reduce the number of patients undergoing unnecessary, extensive lymphadenectomy in the absence of metastatic disease. The addition of novel techniques, such as histopathologic ultrastaging, step sectioning, and immunohistochemistry staining, will help increase the accuracy and rate of detection of the disease. Any definitive statements can be made to the validity of sentinel lymphadenectomy until we got data with long-term follow-up.

In 2014, 9 topics were selected as major advances in clinical research for gynecologic oncology: 2 each in cervical and corpus cancer, 4 in ovarian cancer, and 1 in breast cancer. For cervical cancer, several therapeutic agents showed viable antitumor clinical response in recurrent and metastatic disease: bevacizumab, cediranib, and immunotherapies including human papillomavirus (HPV)-tumor infiltrating lymphocytes and Z-100. The HPV test received FDA approval as the primary screening tool of cervical cancer in women aged 25 and older, based on the results of the ATHENA trial, which suggested that the HPV test was a more sensitive and efficient strategy for cervical cancer screening than methods based solely on cytology. For corpus cancers, results of a phase III Gynecologic Oncology Group (GOG) 249 study of early-stage endometrial cancer with high-intermediate risk factors are followed by the controversial topic of uterine power morcellation in minimally invasive gynecologic surgery. Promising results of phase II studies regarding the effectiveness of olaparib in various ovarian cancer settings are summarized. After a brief review of results from a phase III study on pazopanib maintenance therapy in advanced ovarian cancer, 2 outstanding 2014 ASCO presentations cover the topic of using molecular subtypes in predicting response to bevacizumab. A review of the use of opportunistic bilateral salpingectomy as an ovarian cancer preventive strategy in the general population is presented. Two remarkable studies that discussed the effectiveness of adjuvant ovarian suppression in premenopausal early breast cancer have been selected as the last topics covered in this review.

OBJECTIVETo study the clinicopathologic features and histogenesis of calcifying fibrous tumor (CFT).
METHODSThe clinical manifestations, histopathologic characteristics and immunophenotype were analyzed in 11 cases of CFT.
RESULTSThe male-to-female ratio was 5:6, with a mean age of 38 years and age range of 25 to 52 years. The sites of involvement included abdominopelvic cavity (n=6), soft tissue (n=4) and scrotum (n=1). Most patients presented with a gradually enlarging and painless mass. Nearly half of the cases were associated with other diseases or history of inflammation, trauma or surgical intervention. One third of the tumors represented incidental findings and showed no recurrence after resection. Imaging revealed a solitary solid soft tissue mass or multiple nodules with clear borders and associated high-density calcifications. Macroscopically, the tumors were well-circumscribed but non-encapsulated. They ranged from 0.5 to 20.0 cm in diameter and were tan-greyish, round to oval, lobulated or irregular and solid with rubbery consistency. The cut surface was whitish to tan-yellowish, gritty and showed scattered spotty yellowish discoloration corresponding to the foci of dystrophic calcifications. Histologically, CFT was composed of hyalinized fibrous tissue and thickened vessel walls with interspersed bland spindly fibroblastic cells, scattered psammomatous calcifications, dystrophic calcification and lymphoplasmacytic infiltration. In addition, focal cloak-like polymorph infiltration at the tumor periphery and entrapment of adipocytes and nerves were demonstrated in some cases. Foci resembling solitary fibrous tumor, fibromatosis, keloid or inflammatory myofibroblastic tumor were observed. Immunohistochemical study showed that the tumor cells were diffusely positive for vimentin and focally positive for CD34, factor VIII-related antigen and beta-catenin. The admixed plasma cells were notably IgG positive, with more than 50% being IgG4 positive.
CONCLUSIONSCFT has characteristic histopathologic manifestations and shows morphologic and immunohistochemical overlaps with known IgG4-related sclerosing diseases. It is possible that CFT may represent another example of IgG4-related diseases. It often runs a benign clinical course, with rare recurrence after surgical resection. Previous inflammation and trauma may be the precipitating factors of CFT.

OBJECTIVETo study the clinicopathologic characteristics of perivascular epithelioid cell tumor (PEComa), not otherwise specified (NOS) and to evaluate the diagnostic criteria for malignancy.
METHODSThe clinical and pathologic features of 31 cases of PEComa-NOS were reviewed. The follow-up data available were analyzed.
RESULTSThere were a total of 24 females and 7 males. The age of the patients ranged from 13 to 66 years (mean = 40 years). The site of tumor occurrence included gynecologic organs (n = 12), intraabdominal/peritoneal soft tissue (n = 10), gastrointestinal tract (n = 4), thigh (n = 2), mediastinum (n = 1), left groin (n = 1) and urinary bladder (n = 1). None of the cases was associated with tuberous sclerosis complex. Histologic examination showed that 23 cases (74%) were clear cell sugar tumor-like, 4 cases (13%) were clear cell myomelanocytic tumor-like and 4 cases (13%) were of mixed epithelioid-spindled morphology. According to the classification system proposed by Folpe et al, 19 cases (61%) were classified as malignant, 7 cases (23%) as PEComa of uncertain malignant potential and 5 cases (16%) as benign. The expression rates of HMB45, smooth muscle actin and desmin in tested cases were 100% (31/31), 67% (14/21) and 6/18, respectively. Follow-up data (1 to 56 months) were available in 23 cases (74%). Amongst the 16 cases of malignant PEComa, 7 patients were still alive with no evidence of disease, 6 patients were alive with unresectable or recurrent/metastatic disease and 3 patients died of the disease. The local recurrence and metastasis in those 16 cases were 6 cases and 5 cases, respectively. One of the 4 patients with PEComa of uncertain malignant potential died, while the remaining 3 patients and all of the patients with benign PEComa had an uneventful clinical course.
CONCLUSIONSThe classification system of PEComas proposed by Folpe et al. is reliable in routine practice. Correlation with the clinical and radiologic findings however is prudent when dealing with core biopsy specimens or sampling from exploration laparotomy. Owing to the histologic heterogeneity of this entity, thorough understanding of the morphologic spectrum is essential in arriving at a correct diagnosis.

OBJECTIVETo study the clinicopathologic features of primitive neuroectodermal tumor (PNET) in female genital tract.
METHODSSix cases of PNET arising in female genital tract were retrospectively reviewed. The clinicopathologic features, immunohistochemical findings and EWS gene translocation study results were analyzed.
RESULTSThe age of patients ranged from 10 to 27 years (mean = 20 years). The sites of involvement included ovary (1 case), uterus (1 case), vulva (2 cases) and vagina (2 cases). The greatest diameter of the tumor ranged from 2 to 10 cm (mean = 5.4 cm). The tumor had nodular appearance and showed grayish-pink fleshy cut surface, accompanied by foci of hemorrhage and necrosis. Histologically, the tumor was composed of malignant small round cells with indistinct cell borders, hyperchromatic nuclei, dense chromatin, tiny nucleoli and scanty cytoplasm. The tumor cells were arranged in sheets or lobules. Homer-Wright rosettes were identified in 1 case. Immunohistochemical study showed that the tumor cells were positive for CD99, FLI-1 and CD56 (6/6). Focal expression of vimentin (5/6), NSE (5/6), nestin (4/6), synaptophysin (4/6), S-100 protein (2/6) and chromogranin A (1/6) was also demonstrated. EWS gene translocation was detected in 5 cases studied. Follow-up information was available in 2 patients (7 and 17 months of follow up, respectively). One of them died of tumor metastasis 17 months after diagnosis. The other patient was still alive.
CONCLUSIONSPNET arising in female genital tract is rare. It mainly involves ovary, uterus, vulva and vagina. Immunohistochemical study using a panel of antibodies and fluorescence in-situ hybridization play an important role in definitive diagnosis of this rare malignancy.

Radiotherapy plays a major role in the treatment of cervical cancer. A successful radiotherapy program integrates both external beam and brachytherapy components. The principles of radiotherapy are strongly based on the anatomy of the organ and patterns of local and nodal spread. However, in patients with distorted anatomy, several practical issues arise in the delivery of optimal radiotherapy, especially with brachytherapy. Müllerian duct anomalies result in congenital malformations of the female genital tract. Though being very commonly studied for their deleterious effects on fertility and pregnancy, they have not been recognized for their potential to interfere with the delivery of radiotherapy among patients with cervical cancer. Here, we discuss the management of cervical cancer among patients with Müllerian duct anomalies and review the very sparse amount of published literature on this topic.

OBJECTIVE: A number of new techniques have been developed to prevent lymphocele formation after pelvic lymphadenectomy in gynecologic cancers. We assessed whether the electrothermal bipolar vessel sealing device (EBVSD) could decrease the incidence of postoperative lymphocele secondary to pelvic lymphadenectomy. METHODS: A total of 321 patients with gynecologic cancer underwent pelvic lymphadenectomy from 2005 to 2011. Pelvic lymphadenectomy without EBVSD was performed in 134 patients, and pelvic lymphadenectomy with EBVSD was performed in 187 patients. We retrospectively compared the incidence of lymphocele and symptoms between both groups. RESULTS: Four to 8 weeks after operation, 108 cases of lymphocele (34%) were detected by computed tomography scan examination. The incidence of lymphocele after pelvic lymphadenectomy was 56% (75/134) in the tie ligation group, and 18% (33/187) in the EBVSD group. We found a statistically significant difference in the incidence of lymphocele between both groups (p<0.01). To detect the independent risk factor for lymphocele development, we performed multivariate analysis with logistic regression for three variables (device, number of dissected lymph nodes, and operation time). Among these variables, we found a significant difference (p<0.001) for only one device. CONCLUSION: Use of the EBVSD during gynecological cancer operation is useful for preventing the development of lymphocele secondary to pelvic lymphadenectomy.
