Purpose: A prospective study was carried out to compare the efficacy of liquid-based cytology (ThinPrep) with the conventional Pap smear using a split-sample design in a Turkish university hospital outpatient gynecology clinic., Methods: 4,322 consecutive patients were recruited for the study between 2002 and 2003. All the patients underwent conventional Pap tests followed by a ThinPrep test for screening of cervical cancer. The results were evaluated in terms of the Bethesda III classification. All the patients with abnormal tests underwent colposcopy and directed biopsy., Results: While 2.3% of the specimens were unsatisfactory for evaluation in the conventional Pap test group, this rate was 1.7% for the ThinPrep group. Epithelial cell abnormalities were observed in 42 (1.0%) patients in the conventional Pap test group and in 36 (0.8%) patients in the ThinPrep group. ASCUS was observed in 26 patients in the conventional Pap test group whereas the ThinPrep group had 20 cases of ASCUS as the leading cause of abnormal cytology. Biopsy of these cases revealed CIN 1 in two CIN 2-3 in three and cervical/endometrial adenocarcinoma in three patients. The ThinPrep application led to diagnoses of one additional case of CIN 2-3 and one case of adenocarcinoma among the negative or unsatisfactory for evaluation categories of the conventional Pap test group., Conclusion: Despite an adverse bias introduced by the split-sample study design, application of ThinPrep showed an improved rate of specimen adequacy and increased sensitivity for more significant cervical precursor lesions over the conventional Pap test.

Since malignant transformation in a dermoid cyst is extremely rare, the clinicopathological characteristics of patients with squamous carcinoma arising in dermoid cyst are evaluated in the hope of offering a more rational therapy. Our first patient was lost to follow-up after surgery. In the second patient, with a gross stage III disease, after extensive surgery and multiagent chemotherapy we were able to achieve a remission period of 42 months. In the third patient with pelvic lymph node metastases, adjuvant radiation and chemotherapy was administered following surgical staging. She was free of disease 6 months after surgery. Malignant transformation in a dermoid cyst is a rare complication observed especially in older age groups. Thus, a frozen section in these decades may improve detection of this complication allowing a more accurate staging. Although poor prognosis is reported, an aggressive approach with cisplatinum based chemotherapy and radiation and even with secondary cytoreduction, long-term remission may be achieved.

This study includes 39 patients with squamous carcinoma of the vulva subjected to radical surgery. Stage, tumor description, cell type, lesion localization, lesion size, depth of invasion, grade, lymphovascular space invasion, number of mitoses, degree of stromal inflammatory reaction, and tumors in surgical margins were analyzed for groin metastasis. Of the factors analyzed, stage (P = 0.018), grade (P = 0.007) and depth of invasion (P = 0.001) were found to be the most important predictors of node metastasis. While a combination of factors permitted to define a low-risk group with 0% node metastasis, it seems hard to identify preoperatively those patients with no risk of nodal metastasis.

This study includes 110 patients treated surgically for stage I squamous cell carcinoma of the cervix. The prognostic significances of mitotic activity, stromal inflammatory and eosinophilic reactions were studied. The 5-year survival rate varied from 75.0% to 93.3% and pelvic lymph node metastases (PLNM) varied from 23.0% to 31.2% according to degree of these variables. None of these pathological parameters was found to be a significant predictor of pelvic lymph node metastases and 5-year survival.

This study includes 15 patients with invasive cervical cancer found at the time of standard hysterectomy for benign conditions. All patients underwent laparotomy and were subjected to peritoneal cytology, radical parametriectomy, bilateral pelvic and para-aortic lymphadenectomy. Residual disease was found in 10 of the 15 patients (66.7%). The 3-year survival of patients with and without residual disease were 80% and 100%, respectively. Following secondary radical surgery, five patients without evidence of residual disease were identified and spared the risks of radiation therapy. Furthermore, two patients with para-aortic lymph node metastases, who would otherwise have been overlooked, were thus treated completely. One patient died of complications of secondary surgical procedure.

This study includes 194 patients with stage I cervical cancer subjected to surgical therapy. Of 14 pathological factors analyzed, microscopic parametrial involvement (P = 0.001), depth of invasion (P = 0.001), and lymphovascular space invasion (P = 0.029) were found to be the most significant factors for positive pelvic lymph nodes. Combination of significant factors permitted categorization of patients into risk groups with pelvic lymph node metastases ranging from 0.0% to 90.9%.
