RESUMO

INTRODUCTION: Cervicouterine cancer (CC) is a health problem worldwide and is the fourth most common cancer in women, with a greater proportion of individuals affected by advanced stages of the disease in developing countries. OBJECTIVE: To determine the sensitivity and specificity of the TruScreen™ opto-electronic device vs. conventional cytology in CC screenings. METHODOLOGY: This is a prospective observational study that included individuals who presented for the first time at the Dysplasia Clinic of the Instituto Nacional de Cancerología from March 1 through April 30, 2016, and those referred due to abnormal conventional cytology. The patients were evaluated with the TruScreen™ device, conventional cytology, colposcopy and, if necessary, cervical biopsy. The results were analyzed by descriptive statistics as well as the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the TruScreen™, using conventional cytology as the standard. RESULTS: Thirty-two patients were included who met the inclusion criteria. The average age of the patients was 40 years (range, 23-61 years). For the diagnosis of high-grade intraepithelial lesions, the TruScreen™ device showed a 43% sensitivity, a 92% specificity, a PPV of 60%, and a NPV of 85%, whereas evaluation via cervical biopsy exhibited a 33% sensitivity, an 86% specificity, a 33% PPV, and an 86% NPV. The Kappa agreement index of the TruScreen™ with the colposcopies was 0.70. CONCLUSIONS: TruScreen™ demonstrated low sensitivity and high specificity compared with conventional cytology, which had a high NPV.

RESUMO

BACKGROUND: The aim of the present study was to demonstrate that radical hysterectomy (RH) leads to improved survival outcomes in FIGO stage IB2-IIB cervical cancer when compared with standard brachytherapy (BCT) after identical external beam chemoradiation (EBRT-CT). PATIENTS AND METHODS: EBRT-CT treatment consisted of six courses of cisplatin at 40 mg/m² and gemcitabine at 125 mg/m² per week concurrent with 50.4 Gy of radiation. In the BCT arm, EBRT-CT was followed by BCT to reach a point A dose of 85 Gy, whereas in the experimental arm, a type III RH with bilateral pelvic lymph node dissection and para-aortic lymph node sampling (RH) was carried out within 4-6 weeks after EBRT-CT. RESULTS: Between May 2004 and June 2009, 211 patients were enrolled (BCT, 100 and RH, 111). At a median follow-up time of 36 months (3-80), progression-free survival (PFS) and overall survival (OS) rates were similar in both the arms. PFS rates were 74.8% and 71.7% in the BCT and RH arms [HR 0.6516 (95% confidence interval (CI) 0.3504-1.2116)], P = 0.186. OS rates were 76.3% in the BCT versus 74.5% in the surgical arm [HR 0.6981 (95% CI 0.3106-1.3439)], P = 0.236. No differences were observed in the pattern of local and systemic failures. CONCLUSIONS: This study failed to demonstrate that RH after EBRT-CT is superior to standard BCT.

RESUMO

BACKGROUND: Our aim was to evaluate the efficacy and safety of neoadjuvant chemotherapy followed by radical hysterectomy and adjuvant radiation concurrent with weekly cisplatin for locally advanced cervical carcinoma. PATIENTS AND METHODS: Forty-three patients staged as IB2-IIIB were treated with three 21-day courses of carboplatin (area under the time-concentration curve 6 mg.min/ml) and paclitaxel at 175 mg/m(2) by 3-h infusion both on day 1 followed by radical type III hysterectomy and adjuvant radiation concurrent with 6-weekly doses of cisplatin at 40 mg/m(2). Response rate, resectability, toxicity and survival were evaluated. RESULTS: From December 2000 to June 2001, 43 patients were recruited. All were evaluated for response and toxicity to neoadjuvant chemotherapy. A total of 129 courses were administered. Clinical responses were seen in 41 patients (95%) [95% confidence interval (CI) 89.2% to 100%] with four (9%) complete and 37 (86%) partial. Forty-one patients underwent surgery (resectability 95%); pathologically complete or near-complete responses were seen in seven (17%) and eight (20%), respectively, positive surgical margins in five (12%), and positive pelvic lymph nodes in eight (20%). Twenty-six patients were scheduled for adjuvant chemoradiation. External radiation was delivered for 42.8 days (range 33-61), with a mean dose of 49.3 Gy (range 46-56), and a median of five cisplatin courses (two to six). The mean dose of brachytherapy was 32 Gy (range 25.5-35.6). Neoadjuvant therapy was well-tolerated with neutropenia grade 3 and 4 in 12% and 3% of the courses, respectively. Toxicity to adjuvant chemoradiation was mainly hematological and gastrointestinal, mostly grades 1/2. A total of 39 patients completed all scheduled treatment. At a median follow-up of 21 months (range 3-26), the projected overall survival in the intention-to-treat analysis was 79% (95% CI 62% to 88%). CONCLUSIONS: The triple modality of neoadjuvant chemotherapy followed by radical hysterectomy and adjuvant radiation concurrent with cisplatin is a highly active treatment for locally advanced cervical carcinoma with acceptable toxicity.

RESUMO

BACKGROUND: Randomized studies comparing induction chemotherapy followed by surgical resection with radiation alone found that the neoadjuvant approach produces better results. So far, this latter modality has not been compared with standard concomitant chemoradiation. The objective of this report was to compare the results of two consecutive phase II studies: neoadjuvant chemotherapy followed by surgery or chemoradiation for the unresectable cases versus standard cisplatin-based chemoradiation. PATIENTS AND METHODS: From February 1999 to July 1999, 41 patients with cervical carcinoma, stages IB2-IIIB, were treated with neoadjuvant chemotherapy. Treatment consisted of three 21-day courses of cisplatin 100 mg/m(2) on day 1 and gemcitabine 1000 mg/m(2) on days 1 and 8, followed by either surgery or concomitant chemoradiation for the non-operable cases. From August 1999 to December 1999, an equal number of patients having comparable clinicopathological characteristics were treated with six weekly courses of cisplatin 40 mg/m(2) during standard pelvic radiation. RESULTS: A total of 82 patients were analyzed. Both groups were similar with regard to age, histology, International Federation of Gynecology and Obstetrics (FIGO) stage, tumor size, pretreatment hemoglobin levels, parametrial infiltration and performance status. In the neoadjuvant arm the overall response rate to induction chemotherapy was 95% (95% confidence interval 88% to 100%). Twenty-three patients had surgery and 14 underwent chemoradiation. In the definitive chemoradiation study, 38 patients completed treatment, the median number of cisplatin courses was six for a dose intensity of 33 mg/m(2)/week. Doses to points A and B were 85 Gy (range 68-95) and 55 Gy (range 51-65), respectively. Chemoradiation was delivered in 44.6 (range 28-113) days. Complete response rates after all treatment were similar: 97% and 87% in the neoadjuvant and chemoradiation groups, respectively. At a median follow-up of 28 (range 2-33) and 24 (range 3-30) months, respectively, there were no differences in overall survival. To date, 15 and 13 patients in the neoadjuvant and chemoradiation groups, respectively, have died of disease (P = 0.8567). CONCLUSIONS: The results of this non-randomized comparison suggest that induction chemotherapy followed by surgery or chemoradiation is at least as effective in terms of response and survival as standard cisplatin-based chemoradiation. A randomized study is needed to confirm these findings.

RESUMO

The incidence of developing malignancy in a mature cystic teratoma of the ovary is 1-2%. Most of the reported cases occur in postmenopausal women. This paper reports two cases of squamous cell carcinoma arising in a mature cystic teratoma of the ovary of which one occurred in a young woman. In the other case we could support the fact that the carcinomatous component has its origin in the columnar epithelium and epidermis of the teratomatous tissues.
