Abdominal radical trachelectomy in fertility-sparing treatment of early-stage cervical cancer.

Background: Abdominal radical trachelectomy (ART) is one of the fertility-sparing procedures in women with early-stage cervical cancer. In comparison with vaginal radical trachelectomy, the published results of ART are so far limited. Methods: Enrolled were women referred for ART either by laparoscopy or laparotomy. The main inclusion criterion was stage IA2 or IB1 with a cranial extent that allows for preservation of at least 1 cm of the endocervical canal. Results: A total of 24 women were referred for the procedure, but fertility could not be preserved in 7 (29%) of them. Four women underwent immediate completion of radical hysterectomy because of a positive cranial surgical margin (n = 2) or sentinel node macrometastasis (n = 2) on frozen section. We found no correlation between tumor volume and inability to preserve fertility. A positive sentinel node was identified in 4 patients (17%); there were no false-negative results. Of the 9 women (53%) who have tried to conceive so far, 6 (67%) have conceived and 5 given birth, 2 of which were premature deliveries. Conclusions: Fertility cannot be preserved because of positive cranial margins or involved lymph nodes in almost one third of patients originally referred for radical trachelectomy. The main criterion for the selection of suitable patients should be the cranial extent of the tumor. Abdominal radical trachelectomy allows for achievement of satisfactory obstetrical outcomes.

Late morbidity following nerve-sparing radical hysterectomy☆

OBJECTIVES Nerve-sparing (NS) modification of radical hysterectomy (RH) has been developed with the main purpose of improving the quality of life after radical surgical treatment of early-stage cervical cancer. Although the procedure has been discussed for almost 30 years, there are only limited data available on late morbidity. The aim of the study was to prospectively evaluate the morbidity of patients before and 6 months after NS RH and compare that with the morbidity in patients following different types of parametrectomy without nerve sparing. METHODS Multiple parameters were assessed prospectively using 20-item self-reported questionnaire, focusing on three main areas of morbidity: bladder, sexual, and anorectal functions. Excluded were patients treated with adjuvant radiotherapy. RESULTS Enrolled were women following NS RH (N=32), type C RH (N=19), and type D RH (N=21). Nine parameters significantly deteriorate in the whole group after the treatment: defecation straining (p=0.03), defecation regularity (p=0.0006), defecation frequency (p=0.02), need to use laxatives (p<0.001), flatulence incontinence (p<0.001), urinary incontinence (p<0.001), nocturia (p=0.002), loss of bladder sensation (p=0.04), and straining to void (p<0.001). There were significant differences (p<0.05) between groups following NS and type C or D RH in changes of following parameters: defecation regularity, receptivity to sexual activity, urinary incontinence, nocturia, and straining to void, while no differences were found between type C and D RH. Minimal changes were observed in any of 10 parameters of sexual functions. CONCLUSIONS Our results confirmed a significant negative impact of RH on bladder and anorectal functions. Autonomic nerve preservation significantly improved morbidity 6 months after treatment.

Sentinel node (SLN) biopsy in the management of locally advanced cervical cancer

OBJECTIVES Sentinel lymph node (SLN) biopsy can significantly contribute to the management of locally advanced cervical cancers with high risk of lymph node (LN) positivity. However, low detection rate and sensitivity were reported in larger tumors, albeit on a small number of cases. It was the aim of our study to verify the SLN reliability in large tumors, with modified dye application technique and a careful identification of side-specific lymphatic drainage. METHODS The study involved 44 patients with tumors 3 cm in diameter or larger, stages IB1 to IIA, or selected IIB. In cases where SLN could not be detected, systematic pelvic lymphadenectomy was performed on the respective side. Systematic pelvic lymphadenectomy was performed during the second step radical procedure if not already done. RESULTS Detection rate in the whole cohort reached 77% per patient and 59% bilaterally. No significant difference was found whether a blue dye or a combined method was used (75% vs 80%, and 55% vs 67%). Systematic pelvic lymphadenectomy was performed in cases with undetected SLN unilaterally in 8 and bilaterally in 10 women. A systematic pelvic lymphadenectomy was included in the second step radical procedure in 19 cases and no positive LN were found. There was no case of false-negative SLN result in patients who underwent surgical treatment. CONCLUSION Detection rate in locally advanced cervical cancer could be improved by a careful dye application technique. Low false-negative SLN rate could be achieved if pelvic lymphatic drainage is evaluated on a side-specific principle by performing systematic lymphadenectomy if SLN is not detected.

Local control after tailored surgical treatment of early cervical cancer

Background: It was the aim of our study to analyze oncological outcome and prognostic parameters in patients with early stages cervical cancer after tailored and well-standardized surgical treatment with an adequate follow-up. Methods: Oncological outcome and prognostic parameters were evaluated in a group of 192 patients with cervical cancer stages IA2 to 2B who had undergone radical hysterectomy (n = 171), radical parametrectomy (n = 12), or radical trachelectomy (n = 9). Procedures were classified as type B (n = 72), type C1 nerve sparing (n = 103), or type C2 (n = 17). Results: Event-free and overall 5-year survivals probabilities reached 92.7% (confidence interval, 89.5%-95.9 %) and 94.1% (confidence interval, 90.9%-97.3 %). There was only 1 isolated pelvic recurrence found of the total of 10 recurrences. Adjuvant radiotherapy was given to only 22% of patients. The most significant independent prognostic parameters in stage IB tumors were lymph node status, histological type, and tumor volume, whereas in stage II, the parameters included histological type and tumor volume, the latter being inversely related to the prognosis. Conclusions: We have shown an excellent prognosis, especially local control, after tailored surgical treatment of stages IA2 to IIB of cervical cancer, with low prevalence of adjuvant treatment. Different prognostic parameters were observed for stages IB1/IB2 and IIA/B.

High-risk human papillomavirus DNA in the primary tumor, sentinel, and nonsentinel pelvic lymph nodes in patients with early-stage cervical cancer: a correlation with histopathology.

Introduction: Metastatic involvement of pelvic lymph nodes is the most important prognostic parameter in early-stage cervical cancer. Still, approximately 15% of patients with negative pelvic nodes experience recurrence, most of them in the pelvis. The presence of human papillomavirus (HPV) DNA in histologically negative pelvic nodes is considered a subclinical metastatic spread. Methods: Patients with early-stage cervical cancer referred for surgical treatment were enrolled in the study. Cytobrush technique was used for sample collection from the fresh tissue to avoid any loss of material for histology. Results: Altogether, 49 patients were enrolled in the study. High-risk (HR) HPV DNA was identified in the tumor in 91.8% patients and in the sentinel node or other pelvic nodes in 49.9% patients. Among the 10 HR HPV genotypes detected, HPV 16 was the most frequently represented in both the tumor and the lymph nodes (66.7% and 71.4%, respectively). All metastatic lymph nodes were HR HPV positive. Conclusions: The presence of HR HPV DNA in a sentinel node had a 100% positive predictive value for metastatic involvement of pelvic lymph nodes in our study. This could be considered a sign of an early subclinical metastatic spread; however, the prognostic value has to be evaluated through a longer follow-up.

6.1 months (range 3–30 months), speed growth rate was recorded before a further conservative surgery. Conclusion: TVUS is the most effective procedure in the correct identification of all tumor recurrences and allows further sparingfertility surgery in young patients. In selected cases an observational longitudinal follow-up of recurrences is allowed given their low growth rate, in order to well define time and type of a further conservative minimally invasive surgical approach.

High-risk human papillomavirus DNA in paraaortic lymph nodes in advanced stages of cervical carcinoma

BACKGROUND Paraaortic lymph nodes represent the second level in the lymphatic spread of cervical cancer. Recent studies have confirmed the association of HPV DNA in pelvic lymph nodes in early-stage disease with metastatic involvement and a less favourable prognosis. OBJECTIVE The aim of our study was to detect 13 high-risk genotypes of HPV in paraaortic nodes harvested from patients with FIGO IB2-IIIB tumours and correlate findings with histopathology. STUDY DESIGN The study involved patients with advanced cervical cancer who had undergone low paraaortic lymphadenectomy. The cytobrush technique was used for perioperative sample collection from the tumour and fresh lymphatic tissue. Patients with non-HPV related cancers were used as a control group. RESULTS The study involved 24 cervical cancer patients. High-risk HPV DNA was found in the primary tumour of all cases and in PALN in 16 (67%) cases. The most frequent genotype was HPV 16, both in the tumour and in the paraaortic lymph nodes (83% and 54%, respectively). Metastatic involvement of paraaortic lymph nodes was identified in 8 cases (33%), which all were also HPV DNA positive. No HPV DNA was detected in PALN in any of 22 control group cases. CONCLUSIONS Using the cytobrush technique, the presence of at least one HR HPV genotype in the primary tumour was identified in all the patients. The metastatically involved paraaortic lymph nodes always contained the DNA of at least one HPV genotype present in the primary tumour. Determination of clinical significance of HR HPV DNA presence in histologically negative lymph nodes requires further follow-up of the cohort.

were then calculated. All suspected recurrences underwent surgery and a definitive histological diagnosis was always obtained. Results: Recurrence of BOT was found in 6/44 women (five seropapillary and one mucinous). A unilocular solid cystic aspect was detected in every case; only one papillary projection was found in three cases and two papilla in three cases. The mean height of these projections was 6 (4–7) mm and mean volume 0.50 (0.17–1.34) mL. No blood flow was observed in the solid components and in the cystic wall. Mean papillary MG was 84.2 (68.5–96.6). Mean diameter of relapses was 15.8 (10–28) mm and mean volume 5.89 (0.84–14.5) mL. The ratio between papillary volume and cystic volume was 15.81 (4.8–27)%. Conclusions: Early ultrasound patterns of recurrent BOT seem to be a small unilocular solid cyst with well represented solid components without detectable blood flow. The knowledge of these features may avoid late diagnosis of recurrences or misdiagnosis with functional ovarian cysts in fertile women.

(p < 0.05). Post-operative survival was better in the prenatal group (p < 0.05). At long-term follow up re-intervention-free survival was longer in the prenatal group (p < 0.04). Overall survival at maximum follow up was 92% in the prenatal compared to 84% in the postnatal group (p < 0.18). Conclusions: Prenatal detection of isolated congenital heart defects improves the short and longterm prognosis of the affected children.
