RESUMEN

BACKGROUND: Infections with human papillomavirus (HPV) types 16 and 18 account for ~70% of invasive cervical cancers but the degree of protection from naturally acquired anti-HPV antibodies is uncertain. We examined the risk of HPV infections as defined by HPV DNA detection and cervical abnormalities among women >25 years in the Human Papilloma VIrus Vaccine Immunogenicity ANd Efficacy trial's (VIVIANE, NCT00294047) control arm. METHODS: Serum anti-HPV-16/18 antibodies were determined at baseline and every 12 months in baseline DNA-negative women (N = 2687 for HPV-16 and 2705 for HPV-18) by enzyme-linked immunosorbent assay (ELISA) from blood samples. HPV infections were identified by polymerase chain reaction (PCR) every 6-months, and cervical abnormalities were confirmed by cytology every 12 months. Data were collected over a 7-year period. The association between the risk of type-specific infection and cervical abnormalities and serostatus was assessed using Cox proportional hazard models. RESULTS: Risk of newly detected HPV-16-associated 6-month persistent infections (PI) (hazard ratio [HR] = 0.56 [95%CI:0.32; 0.99]) and atypical squamous cells of undetermined significance (ASC-US+) (HR = 0.28 [0.12; 0.67]) were significantly lower in baseline seropositive vs baseline seronegative women. HPV-16-associated incident infections (HR = 0.81 [0.56; 1.16]) and 12-month PI (HR = 0.53 [0.24; 1.16]) showed the same trend. A similar trend of lower risk was observed in HPV-18-seropositive vs -seronegative women (HR = 0.95 [0.59; 1.51] for IIs, HR = 0.43 [0.16; 1.13] for 6-month PIs, HR = 0.31 [0.07; 1.36] for 12-month PIs, and HR = 0.61 [0.23; 1.61] for ASC-US+). CONCLUSIONS: Naturally acquired anti-HPV-16 antibodies were associated with a decreased risk of subsequent infection and cervical abnormalities in women >25 years. This possible protection was lower than that previously reported in 15- to 25-year-old women.

RESUMEN

INTRODUCTION: The Wertheim's radical abdominal hysterectomy (RAH) has been the traditional surgical approach for operable Stage IB cervical cancer in Singapore whereas total laparoscopic radical hysterectomy (TLRH) was introduced only in 2009. In this study, we aimed to compare the long-term surgical outcome between the two routes of surgery in our center. METHODS: This is a prospective study performed in a single large tertiary institution in Singapore. Inclusion criteria included surgically fit patients with early cervical cancer and no radiological evidence of regional or distant metastases. RESULTS: From November 2009 to December 2014, 51 TLRHs and 85 RAHs were performed. Median blood loss in the TLRH group was significantly lower than in the RAH group (300 vs. 500 mL; P = 0.002) as was median hospital stay (5 vs. 6 days; P = 0.001). Operative time was significantly higher in the TLRH group (262 vs. 228 min; P < 0.001). There was no significant difference in bladder recovery. Intraoperative complications were encountered in 2 (3.9%) TLRH patients and 1 (1.2%) RAH patient. Postoperative complications occurred in 3 (5.9%) TLRH patients and 8 (9.4%) RAH patients. With a median follow-up of 117 (range 1.6-314.6) weeks in the TLRH group and 143.3 (range 0.4-304.7) weeks in the RAH group, 9 (17.6%) TLRH patients and 7 (8.2%) RAH patients had recurrence. There was no significant difference in the overall 3-year survival between the TLRH group and the RAH group for tumor size ≤2 cm (100.0% vs. 97.0%; P = 0.37). However, there was a trend toward lower survival for the TLRH group for tumor size >2 cm (61.9% vs. 85.4%; P = 0.06). CONCLUSION: The results of our study suggest that with appropriate patient selection, TLRH can be a safe and effective procedure for the management of early cervical cancer in Singapore, especially in women with small tumors ≤2 cm but should be used with caution in women with larger tumors.

RESUMEN

A 41-yr-old lady with abnormal uterine bleeding underwent total abdominal hysterectomy. Histologic assessment revealed an endometrial stromal sarcoma (ESS) with minimal cytologic atypia and low mitotic count (up to 7/10 high-power fields) with only focal myxoid areas, morphologically corresponding to a low-grade ESS. Immunohistochemical stains showed cyclin D1 and CD10 positivity, and negative staining for CD117 and progesterone receptor. This tumor was clinically aggressive and recurred 6 mo later. The patient died 19 mo following initial diagnosis. Molecular analysis revealed a ZC3H7B (exon 10)-BCOR (exon 7) gene fusion. Subsequent BCOR immunohistochemistry was weakly positive. ESS with ZC3H7B-BCOR gene fusion is classified as a low-grade ESS in some classification schemes, and is also characterized as being typically myxoid. This report supports emerging evidence that ESS with ZC3H7B-BCOR gene fusion may have an aggressive clinical course in spite of its low-grade histology. This report further expands the morphologic spectrum of ZC3H7B-BCOR fusion ESS to include nonmyxoid histology. Finally, this report underlines the value of molecular analysis in the proper classification of this aggressive tumor with deceptive low-grade histology.

RESUMEN

OBJECTIVE: Gynecologic cancer is associated with long-term effects that can be both physical and emotional. We examined symptom prevalence and body image disturbance in patients with gynecologic cancer and their association with quality of life. Predictors of clinically-relevant body image disturbance were examined. METHODS: A sample of patients in Singapore (n = 104) was assessed for symptom prevalence, quality of life, and body image dissatisfaction. Clinical factors were extracted from medical records. RESULTS: The most frequently reported symptoms were fatigue, abdominal bloatedness, weight gain, constipation, hot flashes, and pelvic pain. Approximately one quarter patients reported feeling less physically attractive and dissatisfied with their body. Ordinary least squares regression indicated that symptom prevalence alone predicted physical well-being, b = -1.09, P < .001, 95% CI, -1.45 to -0.73, and functional well-being, b = -0.88, P < .001, 95% CI, -1.32 to -0.45. Body image dissatisfaction alone significantly predicted emotional well-being, b = -0.21, P < .01, 95% CI, -0.35 to -0.06. Younger age was a significant risk factor for clinically-relevant score of body image distress, OR = 0.95 per year older, 95% CI, 0.92 to 0.99, P = .02. CONCLUSIONS: Symptom prevalence and body image dissatisfaction were associated with different domains of quality of life. Emotional well-being of patients was better explained by body image, rather than extent of symptoms experienced. Patients who are younger appear particularly susceptible to body image disturbance.

RESUMEN

Proximal-type epithelioid sarcoma (PES) of the vulva is an exceedingly rare soft tissue tumor with an unpredictable symptom pattern and frequent recurrences. Information on management is limited. This report describes a 51-year-old woman with proximal-type epithelioid sarcoma of the vulva which was resected surgically and reviewed the current medical literature regarding the diagnosis and management of this disease.

RESUMEN

PURPOSE: To describe the initial experience of laparoscopic hand-assisted Miami pouch in a group of patients undergoing pelvic exenterations for pelvic malignancies. MATERIALS AND METHODS: Thirteen female patients underwent laparoscopic-assisted pelvic exenteration in our center between September 2000 and November 2007. Six of them had the Miami pouch created for urinary diversion. The continent diversion was created extracorporeally through a right iliac fossa minilaparotomy. RESULTS: The mean total operative time for the laparoscopic-assisted exenteration and reconstruction was 382 minutes (range, 270-480 minutes), but specifically for the Miami pouch, it took a mean time of 106 minutes (range, 90-130 minutes). Four patients (66.7%) had postoperative urinary tract infection that resolved with antibiotics. One patient had a ureteral stenosis requiring stenting and one had a Miami pouch cutaneous fistula that required a fistulectomy. The mean follow-up was 23 months (range, 9-48 months). All patients were continent and were able to self-catheterize approximately 3 to 6 times/d. CONCLUSIONS: It is technically feasible to incorporate the creation of the Miami continent urinary pouch through a minilaparotomy during laparoscopic pelvic exenteration without compromising the benefits of laparoscopic surgery.
