Introduction:Introduced in 1992, the Shimodaira-Taniguchi conization procedure addresses the disadvantages of the loop electrosurgical excision procedure by relying on a high frequency current of 150 W and a triangular probe with a 0.25-mm linear excision electrode to extract a single informative specimen. We conducted a retrospective study to evaluate Shimodaira-Taniguchi conization as a conservative therapy for cervical intraepithelial neoplasia (CIN) and microinvasive cancer of the cervix.Methods:Subjects were 455 patients who underwent Shimodaira-Taniguchi conization for CIN, carcinoma in situ, adenocarcinoma in situ, or stage IA microinvasive cervical carcinoma at our hospital from January 2005 to December 2008. Patient follow-up ranged from 13 to 60 months. Clinical data were obtained and evaluated.Results:Mean operation time was 11 minutes, and average blood loss was 9.9 mL. Margins were positive in 178 (39.1%) cases. Postsurgical complications occurred in 61 patients, with secondary hemorrhage occurring in 46 patients. None required transfusion. None were lost to follow-up, and there was no disease-related death. Disease recurred in 6 (1.3%) patients: 4 with a positive excision margin and 2 with a negative margin. Cervical stenosis occurred in 15 (3.3%) patients, 3 of whom suffered cervical obstruction, including 1 with dysmenorrhea who underwent hysterectomy. In most cases (n = 357, 78%), a single adequate specimen was extracted.Conclusions:As a conservative treatment for CIN and microinvasive cervical cancer, Shimodaira-Taniguchi conization is useful. It is easy, provides adequate histologic specimens (often singular), and results in few postoperative complications.

Aims: To evaluate the treatment outcome and acceptance of LEEP in precancerous cervical lesions.Methods: This is a descriptive study performed in Gynecology Department of Civil Service Hospital, from August 2014 - December 2015 in 28 cases that underwent LEEP forCIN. LEEP was performed as day care procedure under intravenous anesthesia and patient was sent home six hours after procedure. Follow up and further treatment was done after final histopathological reports.Results: Highest percentage ofCIN, 32.14% (9) was seen among 30-39 years age with 16 (57.14%) of parity three and more. 17 (60.71%) presented clinic with symptoms (lower abdominal, backpain, pervaginal discharge) while 11 (39.28%) were diagnosed from routine Pap test. Histopathology revealed four (14.28%)CIN1, eight (28.57%)CIN2, 11(39.28%)CIN3, two adenocarcinoma in situ, one of invasive squamous cell carcinoma, chronic cervicitis and atrophic change with no dysplasia. Margins were negative (satisfactory) in 20 (71.42%) and positive in eight (28.57%) with endocervical involvement in two that required second LEEP while one underwent radical hysterectomy for final diagnosis of invasive squamous cell carcinoma.Conclusions: Hysterectomy is a radical procedure for preinvasive cervical lesions that can be treated with simple procedure like LEEP that saves time and financial resources.

Abstract Objectives To assess whether modified hysterectomy can improve locoregional control compared to the standard extrafascial hysterectomy for cervical high grade intraepithelial neoplasia 3 (CIN3)/adenocarcinoma in situ (AIS) patients. Methods A total of 135 CIN3/AIS patients from May 2014 to March 2018 were enrolled and randomized to different hysterectomy group and finally 128 patients were eligible for analysis, in which 60 patients received standard extrafascial hysterectomy and 68 patients received modified hysterectomy by removing extra 1.5cm of vagina. Intra-operative variables including operative time, estimated amount of blood loss, urinary catheter time, hospital stay time and postoperative complications, most importantly the postoperative recurrence and disease free survival (DFS) were compared and analyzed. Results Age, BMI and histology grade were comparable between these two groups. No significant differences were found at median surgical times, blood loss and postoperative hospital stay neither laparoscopicly nor abdominally, and neither was found about the incidences of fistulas, or other surgical complications. No incidences of prolonged urinary retention were found in both groups. With a median follow-up of 47.3 months (range 11–64 months), the modified hysterectomy group and had a significantly improved in DFS rate compared to the standard extrafascial hysterectomy group (P = 0.026). No disease related death occurred in the follow-up time. Conclusion With similar intra-operative variables operative time, modified hysterectomy appeared to provide the most reliable specimens and significantly reduced the postoperative vaginal recurrence rate for CIN3/AIS patients who choose remove their uterus when compared with standard extrafascial hysterectomy.

Abstract Context. Atypical glandular cell (AGC) Papanicolaou (Pap) test interpretations are challenging. Most biopsy findings are benign, but AGC results may also reflect highly significant noninvasive neoplastic and malignant histologic outcomes. High-risk human papillomavirus (hrHPV) test use with AGC Pap test results is evolving. Objective. To further evaluate the utility and limitations of hrHPV testing with AGC Pap tests. Design. Hospital records were searched for AGC Pap tests results from June 1, 2005, to August 31, 2007. Cases of AGC with hrHPV tests and histopathologic follow-up were included. Results. Of the 662 women with AGC Pap test results and follow-up analyzed, hrHPV results were available for 309 (46.7%) and were positive in 75 cases (24.3%). Among the 75 cases with hrHPV+ AGC results, 13 (17.3%) had cervical intraepithelial neoplasia grades 2/3, 10 (13.3%) had adenocarcinoma in situ, and 3 (4.0%) had cervical invasive adenocarcinoma, whereas for 234 women with hrHPV− results, 1 (0.4%) had cervical intraepithelial neoplasia grades 2/3, 1 (0.4%) had adenocarcinoma in situ, 1 each (0.4%) had cervical adenocarcinoma and ovarian carcinoma, and 8 (3.4%) had endometrial carcinoma. Conclusions. Positive hrHPV AGC results were most strongly associated with cervical intraepithelial neoplasia grades 2/3 and adenocarcinoma in situ in women younger than 50 years. Positive hrHPV AGC results were also present in all 3 cases of invasive cervical adenocarcinoma in women younger than 50 years. Of note, hrHPV− AGC results were present in 10 of 13 carcinomas (76.9%) detected after AGC Pap tests, all in women 40 years or older with endometrial adenocarcinomas (n  =  8), ovarian carcinoma (n  =  1), and cervical adenosquamous carcinoma in a woman (n  =  1) in her 50s. Testing for hrHPV after AGC Pap testing was most helpful in the detection of cervical intraepithelial neoplasia grades 2/3, adenocarcinoma in situ, and invasive cervical adenocarcinomas in women younger than 50 years.

Slow Growing

Bowen’s disease, also known as intraepithelial neoplasia, is a very slow-growing carcinoma in situ. It can progress to an invasive squamous cell cancer and infiltrate mucosa or skin in 3 to 5% of cases. The anal localization of this disease is very rare. Surgical resection is the standard of treatment. Radiotherapy keeps its place in recurrent or unresectable cases. We report a case of Bowen’s anal canal disease in order to verify the effectiveness of Radiotherapy. He is a 59-years-old patient diagnosed with Bowen’s anal canal disease at the National Institute of Oncology in Rabat. He was treated with exclusive radiotherapy at a dose of 60 Gray in 30 fractions over 49 days. The evolution was marked by a complete clinical and radiological response and preservation of the anal sphincter with an 18 months follow-up.

Introduction. The purpose of this study was to evaluate the role of renal cryoablation in patients with solitary kidneys with the goals of tumor destruction and maximal renal parenchymal preservation.Methods. Eleven patients with single tumors were treated with cryoablation, of which 10 patients had solitary kidneys and 1 had a nonfunctioning contralateral kidney. All procedures were performed via an open extraperitoneal approach; ten tumors were treated with in-situ cryoablation and 1 tumor was treated with cryo-assisted partial nephrectomy.Results. Cryoablation was successfully performed without any preoperative complications. Mean patient age was 62.4 years (range 49–79), tumor location included: 6 (upper pole), 2 (mid-kidney), 3 (lower pole). The mean and median tumor size was 2.6 cm and 2.8 cm (range 1.2–4.3 cm), mean operative time 205 minutes (range 180–270 minutes), blood loss 98.5 ml (range 40–250 ml), and hospitalization 4.6 days (range 3–8 days). Creatinine values included: preoperative 1.43 mg/dL (range 1.2–1.9), postoperative 1.67 mg/dL (range 1.5–2.5), and nadir 1.57 mg/dL (range 1.3–2.1). All patients were followed postoperatively with magnetic resonance imaging for surveillance. At a median follow-up of 43 months, 9 patients had no evidence of recurrence, 1 patient has an enhancing indeterminate area, and 1 patient was lost to follow-up.Conclusion. Intermediate-term results suggest that renal cryoablation offers a feasible alternative for patients that require a maximal nephron-sparing effort with preservation of renal function and minimal risk of tumor recurrence.

ObjectivesSuperficially invasive stage IA squamous vulvar cancer (VSCC) is defined as a single lesion measuring ≤2 cm with a depth of invasion of ≤1.0 mm (FIGO stage IA). This article examines the natural course and prognosis of superficially invasive VSCC.MethodsThis is a retrospective case series of 46 patients (median age 58 years) with superficially invasive stage IA VSCC receiving wide local excision between January 1996 and November 2014 in the University Medical Center Hamburg-Eppendorf.ResultsMedian tumor size was 4 mm. In 39/46 (84.8%) patients peri-tumoral high-grade intraepithelial neoplasia (HSIL) and/or lichen sclerosus (LS) of the vulva were histologically detected: 34 (74.0%) usual type high-grade vulvar intraepithelial neoplasia (uVIN, HSIL), 4 (8.7%) LS with simultaneous VIN (3 uVIN, 1 differentiated VIN (dVIN)), 1 (2.2%) with LS only. 37/46 (80.4%) patients had a R0 resection; in 2 (4.3%) a high-grade VIN was detected in the margin and in 7 (15.2%) the resection status was unknown. The mean follow-up was 58 (range 10–185) months. Four patients (8.7%) suffered from an invasive recurrence after 4, 17, 40, and 54 months, three in the vulva and one in the groin. All local recurrences occurred in women with LS in a combination with high-grade VIN (3 uVIN, 1 dVIN). Two were treated surgically again including inguino-femoral lymphadenectomy (ifLAE) (no regional lymph node metastasis histologically) as invasion depth exceeded 1 mm. The third patient refused treatment. Inguinal recurrence was treated with a bilateral ifLAE, revealing one positive lymph node, followed by adjuvant radiotherapy (groins, pelvis). None of these patients had experienced further recurrences at last follow-up.ConclusionsSuperficially invasive VSCC is characterized by having a very good prognosis. Sole surgical therapy is highly effective. Patients with LS might benefit additionally from intensified surveillance and adequate maintenance therapy in specialized centers.
