[show abstract] [hide abstract]
ABSTRACT: To assess the clinical feasibility of 3-dimensional (3D) proton magnetic resonance spectroscopy (MRS) of ovarian masses at 1.5 T. We prospectively evaluated 16 patients with 23 ovarian masses using contrast-enhanced magnetic resonance imaging and 3D chemical shift imaging MRS (time of reception/time of echo = 700/135 ms, number of excitations = 6, interpolated voxel = 5 × 5 × 5 mm(3), water and fat suppression). Spectral editing consisted of water reference, filtering, zero-filling, Fourier transformation, frequency shift, automatic baseline and phase correction, and curve fitting. The volume of interest was placed to encompass both solid and cystic tumor components as well as apparently healthy pelvic tissues. The presence of a choline peak at 3.14 to 3.34 ppm was considered as a marker of malignancy. All patients underwent surgery and histopathological evaluation. Of 23 masses, 19 were malignant and the remaining 4 benign lesions were a fibrothecoma, an endometriosis, a cyst, and a cystadenofibroma. A choline peak was detected in 17/19 malignant tumors (sensitivity 89%), absent in 2 G1 tumors. It was visible in 16 solid components of 19 malignant tumors (in one of them, a choline peak was detected only in the cystic component, in 6 in both solid and cystic components). The choline peak was absent in 20/21 apparently healthy pelvic tissues, with a very low choline peak being detected in one intraperitoneal fluid collection with malignant cells at cytologic analysis; 3/4 benign tumors showed a choline peak (overall specificity 21/25 = 84%). A significant difference between the mean choline peak integral detected within the solid component and that within the cystic component was observed (P = 0.002). No correlation between the choline peak integral and the tumor size was found (r = 0.120, P = 0.615). 3D MRS of ovarian masses is clinically feasible at 1.5 T. This opens new research strategies for early diagnosis of ovarian cancer.Investigative radiology 04/2011; 46(6):377-82. · 4.85 Impact Factor -
Article: Class III NSRH: oncological outcome in 170 cervical cancer patients.
[show abstract] [hide abstract]
ABSTRACT: To analyze local recurrence rate (LRR), morbidities and oncologic outcome of class III nerve-sparing radical hysterectomy. 170 consecutive class III NSRH cases were performed. Nineteen patients were addressed directly to surgery whilst neoadjuvant chemotherapy was administered in 151 patients. The majority of patients had SCC (75%). The median follow-up was 31 months. The mean age was 50 [27-78] years. Mean post-operative hospital stay was 7 [3-16] days. 2 intraoperative complications occurred. Operating time and blood loss was similar to the state-of-the-art of conventional radical hysterectomy. Overall G3-4 complication rate was 8.2 % (14/170). Early G3-4 complication rate was 3.5% (6/170). Late G3-4 complication rate was: 4.7%. (8/170). Positive pelvic nodes were noted in 31 patients (18.2%). Vagina and parametrial involvement were present in 38 (22%) and 27 (15.8%) patients, respectively. LRR was 10% (17/170). The sites of relapse were: 12 pelvic, 5 vaginal. There were 9 patients DOD. The 2-year and 5-year DFS rates were 89% and 81%, respectively. Univariate and multivariate analysis identified vagina involvement and postoperative treatment as significant prognostic factors. The oncologic results of NSRH were similar to the state-of-the-art of conventional radical hysterectomy. Two years DFS in relation to FIGO stage of disease was 92.3, 89.2 and 86.1 % respectively for IB1, IB2, IIB comparable to literature data. The early and late complications rate related to autonomic injury was significantly lower. The nerve-sparing technique should be considered in all cervical cancer patients addressed to surgery.Gynecologic Oncology 11/2010; 119(2):192-7. · 3.89 Impact Factor -
Article: Quality of life and sexual, bladder, and intestinal dysfunctions after class III nerve-sparing and class II radical hysterectomies: a questionnaire-based study.
[show abstract] [hide abstract]
ABSTRACT: To compare quality of life and bladder, intestinal, and sexual dysfunctions in 2 groups of patients undergoing different types of radical hysterectomies (RHs). Patients with cervical cancer who underwent RH have been enrolled in a questionnaire-based study. Quality of life (QoL) and bladder, intestinal, and sexual dysfunctions were evaluated with the Functional Assessment of Cancer Therapy-Cervix (FACT-Cx). Patients were grouped according to the type of RH: group 1, class II RH and group 2, class III nerve-sparing RH (NSRH). Of 157 women included in the study, 127 filled out the questionnaire. Overall, QoL score assessed with the FACT questionnaire did not differ significantly between the 2 groups. The FACT subscales assessing physical, functional, emotional, and social well-being did not differ significantly between the 2 groups, whereas the FACT-Cx subscales assessing disease-related symptoms in group 2 patients showed a significantly worse score (72 vs 66; P = 0.03). Evaluating singularly the 15 items of the Cx subscales assessing disease-related symptoms, we did not find any significant difference between the 2 groups, but only Cx1 ("I am bothered by discharge or bleeding from my vagina") was significantly worse in group 2 patients. At univariate analysis, we found that NSRH and adjuvant radiotherapy (RT) impact negatively on the FACT-Cx subscales regarding pelvic visceral function. However, at multivariate analysis, only adjuvant RT impact negatively. Patients submitted to class III NSRH did not present worse QoL and pelvic visceral dysfunctions when compared with class II RH. The RT seems to be a factor impacting negatively on bladder and sexual function.International Journal of Gynecological Cancer 08/2009; 19(5):953-7. · 1.65 Impact Factor -
Article: Nerve-sparing radical vaginectomy: two case reports and description of the surgical technique.
[show abstract] [hide abstract]
ABSTRACT: Radical vaginectomy (RV) is related to significant bladder dysfunctions. We describe 2 cases of RV with nerve-sparing technique (NSRV). A 58-year-old woman with a diagnosis of locally advanced cervical cancer underwent neoadjuvant chemotherapy with local and nodal progression of disease. The patient underwent NS radical hysterectomy plus NSRV, with prompt recovery of bladder function. A 14-year-old adolescent girl with a diagnosis of recurrent embryonal-botryoidal rhabdomyosarcoma was referred to us. She underwent 6 courses of chemotherapy with persistent disease. She then underwent NSRV. Two months after the surgical procedure, she was able to void the bladder. These are the first 2 cases of NSRV reported in literature. This new surgical technique is feasible, with prompt recovery of bladder function.International Journal of Gynecological Cancer 06/2009; 19(4):794-7. · 1.65 Impact Factor -
Article: Hysteroscopy in endometrial cancer: new methods to evaluate transtubal leakage of saline distension medium.
[show abstract] [hide abstract]
ABSTRACT: This study was undertaken to evaluate transtubal fluid leakage after low pressure office saline solution hysteroscopy. Forty stage I/II endometrial cancer patients were submitted to office hysteroscopy at the National Cancer Institute of Milan. Uterine cavity was distended by a 1000-mL saline solution bag, placed 50 cm above the patient's plane. After visualization of uterine cavity, a radiotracer (technetium Tc 99m) and patent blue dye were injected subendometrially. During the staging surgery peritoneal free fluid was analyzed to detect patent blue dye, technetium Tc 99m or free cancer cell by cytologic examination. Technetium Tc 99m and patent blue dye were detected on the peritoneal surface and in the peritoneal fluid in 2 patients. In 1 of these peritoneal cytology was negative for cancer cells. Peritoneal cytology was positive in 2 cases. The risk of transtubal fluid leakage during hysteroscopy is absent when performed with intrauterine pressure less than 40 mm Hg. Transtubal fluid leakage is not a synonym of cancer cell dissemination.American journal of obstetrics and gynecology 03/2008; 198(2):214.e1-4. · 3.28 Impact Factor -
Article: Incidental diagnosis of primary vaginal adenocarcinoma of intestinal type: a case report and review of the literature.
[show abstract] [hide abstract]
ABSTRACT: Primary vaginal adenocarcinoma of intestinal type is a rare malignant gynecologic disease. A 53-year-old woman was admitted to our institution with a diagnosis of endometrial adenocarcinoma. A physical examination revealed a 2-cm polypoid lesion of the vagina. The patient underwent surgery for endometrial cancer and wedge resection of the vaginal lesion. The diagnosis of primary vaginal adenocarcinoma of intestinal type was obtained after standard and immunohistochemical analyses of the specimen. No endometrial cancer was detected in the specimen. Radiological investigations excluded metastasis from the gastrointestinal tract. Subsequently, the patient underwent concomitant chemoradiation. At present, 32 months later, she is well and disease-free. Extensive radiological investigations and careful immunohistochemical analysis of the specimen are needed for a correct diagnosis of vaginal adenocarcinoma of intestinal type. Concomitant chemoradiation, as a primary treatment, should be considered.International Journal of Gynecological Pathology 11/2007; 26(4):490-3. · 1.45 Impact Factor -
Article: Nerve-sparing radical hysterectomy in cervical cancer: evolution of concepts.
[show abstract] [hide abstract]
ABSTRACT: This paper reviews the evolution of concepts concerning the nerve-sparing radical hysterectomy (NSRH) in cervical cancer. Research studies published between 1991 and 2006 were reviewed. Significant progress has been made in understanding the neuroanatomy and the neurophysiology of autonomic pelvic plexus. The ideal surgical management of cervical cancer patients should be tailored on the basis of prognostic factors and quality of life. Within the discussion concerning the optimal level of radicality of hysterectomy, which is still controversial, the new concept of NSRH has to be considered in order to reduce morbidity without compromising the oncological disease control. Surgical strategies have been developed to spare the autonomic functions with promising results. To date, there is a growing body of data about NSRH in cervical cancer. However, there is not yet a consensus concerning to which part of uterine support ligaments a NS approach should be directed.Gynecologic Oncology 11/2007; 107(1 Suppl 1):S119-21. · 3.89 Impact Factor -
Article: Type II versus Type III nerve-sparing radical hysterectomy: comparison of lower urinary tract dysfunctions.
[show abstract] [hide abstract]
ABSTRACT: According to our previous experience, Type III Nerve-sparing Radical hysterectomy (NSRH) for cervical cancer presented an acceptable urologic morbidity, without compromising radicality. The aim of this study was to compare Type NSRH with other types of RH in terms of incidence of early bladder dysfunctions and perioperative complications. One hundred and ten patients with cervical cancer were submitted to Type II RH (group 1), Type III NSRH (group 2) and Type III RH (group 3). We assessed the postoperative early bladder function and complications. The follow-up period was 3 months. Group 1 had a significantly shorter duration of the surgery, minor mean blood loss and shorter mean length of postoperative stay when compared to groups 2 and 3. No intraoperative complications were reported in either of the groups. The groups did not differ significantly in terms of GIII/IV morbidity (group 1 = 10%, group 2 = 10% and group 3 = 15%, chi(2), P value: 0.65). Not even they differed in terms of urologic GI-IV morbidity (group 1 = 13%, group 2 = 15% and group 3 = 10%, chi(2), P value = 0.88). Groups 1 and 2 presented a prompt recover of bladder function, significantly different from that of group 3. There was a significant difference between the groups regarding the number of patients discharged with self-catheterism (group 1 = 0; group 2 and group 3 = 11; chi(2), P value < 0.05). The Type III NSRH seems to be comparable to Type II RH and superior to Type III RH in terms of early bladder dysfunctions.Gynecologic Oncology 09/2006; 102(2):256-62. · 3.89 Impact Factor -
Article: Clinical and pathological prognostic factors in squamous cell carcinoma of the vulva.
[show abstract] [hide abstract]
ABSTRACT: The objective of this study was the prognostic analysis of clinicopathologic variables related to primary tumor and to lymph node metastases. We retrospectively analyzed 389 cases of squamous cell carcinoma of the vulva. The following variables were studied: patients' age, diameter and location of the tumor, clinical tumor characteristics, depth of invasion, grade, lymphovascular space involvement (LVSI) and lymph node status. In the subset of 110 node positive patients, we evaluated number of positive nodes, laterality, extension of node dissection, lymph node chains involved, presence of extracapsular spread and rate of lymph node replacement. All variables with P value < 0.2 by the univariate analysis were successively subjected to multivariate analysis (Cox proportional hazard model). Among all the tumor-related variables age, clinical tumor characteristics, LVSI and lymph node status were found to be statistically significant predictors of survival for the log-rank test. On the basis of multivariate analysis, the nodal status was the most significant independent prognostic factor (hazard rate [HR]: 2.06; confidence interval [CI] 95%: 1.57-12.07) followed by LVSI (HR: 3.47; CI95%: 1.85-7.85). The independent prognostic factors among the variables relative to positive nodes were the percentage of nodal replacement (HR: 6.99; CI95%: 3.51-16.14) and the extracapsular spread (HR: 4.88; CI95%: 2.96-10.14). Lymph node status and nodal features, such as extracapsular spread and nodal replacement rate, were shown to be independent factors. These factors should be considered to identify high risk patients and in planning further adjuvant therapy.Gynecologic Oncology 08/2006; 102(2):333-7. · 3.89 Impact Factor -
Article: Nerve-sparing radical hysterectomy: a surgical technique for preserving the autonomic hypogastric nerve.
[show abstract] [hide abstract]
ABSTRACT: Recently, a nerve-sparing radical hysterectomy has been proposed for cervical cancer to reduce morbidity. The aim of this study is (i) to describe the surgical anatomy of the autonomic nervous system, (ii) to describe a new nerve-sparing technique for Piver III radical hysterectomy (RH) using the CUSA, in which greater attention was paid to the autonomic nervous pathway, and (iii) to assess the feasibility and the impact of this nerve-sparing technique on the incidence of early bladder dysfunctions. Twenty-three patients with cervical cancer were submitted to nerve-sparing Piver III RH with pelvic lymphadenectomy. Postoperative assessment of bladder function consisted draining the bladder for 3 days using Foley catheterization. Then, we started draining the bladder every 3 h with a no. 10 French catheter to register the onset of spontaneous voiding and to assess the postvoid residual urine volume (PVR). The nerve-sparing technique were performed satisfactorily in all cases. The mean operating time was 219 min (range: 150-270). The mean blood loss was 489 ml (range: 200-800). The average period of hospitalization was 10 days (range: 5-16). Two (9%) patients were discharged with self-catheterization, and one of them recovered the ability to void her bladder spontaneously by the time of her first visit to the outpatient clinic. This nerve-sparing RH technique using the CUSA proved feasible, with promising results in terms of preventing early bladder dysfunction. The average time between surgery and the onset of spontaneous voiding was acceptable. Further prospective controlled studies are needed to confirm our data.Gynecologic Oncology 06/2004; 93(2):307-14. · 3.89 Impact Factor -
Article: Gemcitabine combined with oxaliplatin (GEMOX) as second-line chemotherapy in patients with advanced ovarian cancer refractory or resistant to platinum and taxane.
[show abstract] [hide abstract]
ABSTRACT: The aim of this multicenter feasibility study was to determine the toxicity profile and antitumor activity of the gemcitabine plus oxaliplatin combination as second-line treatment in platinum plus paclitaxel resistant/refractory advanced ovarian cancer. Twenty patients received a 30-60-min infusion of gemcitabine a week for 2 weeks, followed by 120-180 min infusion of oxaliplatin every 3 weeks. The doses used were 1,000 and 130 mg/m(2), respectively. Seventeen cases (85% of the total) were platinum resistant and 3 (15%) were platinum refractory. Grade 3/4 thrombocytopenia occurred in 14/20 of cases (70%); there were no symptomatic cases. 2 patients required platelet transfusion and 8 patients received hydrocortisone. The dose- limiting toxicity was thrombocytopenia. Combined grade 3/4 neutropenia was observed in 8/20 (40%) of cases (no sepsis was registered). Five patients were treated with recombinant erythropoietin because of grade 3 anemia and 4 cases received G-CSF prophylactically from the first cycle. The overall response rate of the combination in terms of antitumor activity was 26% (95% CI = 9-51%). A combination of gemcitabine and oxaliplatin using this schedule gave rise to a moderate/severe toxicity profile and would be feasible only if growth factors were used and/or gemcitabine were administered at lower doses. The antitumor activity of the combination was insufficient reward for the resultant toxicity profile. However, equivalent to that of other drugs used in platinum refractory and resistant patients.Oncology 02/2004; 67(5-6):376-81. · 2.27 Impact Factor -
Article: Microinvasive squamous cell cervical carcinoma.
[show abstract] [hide abstract]
ABSTRACT: Several histologic tumor-related features are the key factors for further treatment planning in microinvasive cervical cancer (MIC) after conization. To better define the indications for conservative treatment of MIC we conducted a literature review for prognostic factors for MIC and we carried out a prospective observational study evaluating most important pathologic factors and the relationships between tumor and edges of the cone and incidence of recurrences. In our experience seven recurrences were observed. Two distinct groups of patients were identified with a clearance lower or higher of 10 and 8 mm for apical and lateral margin respectively. Depth of infiltration and even lymph-vascular involvement have been confirmed as the most important histologic parameters to be evaluated. Apical and lateral clearance of the tumor are significantly correlated with the recurrence rate. If an adequate lateral border of healthy tissue is present on the specimen, conization may be considered as definitive treatment of MIC.Critical Reviews in Oncology/Hematology 01/2004; 48(3):251-61. · 4.41 Impact Factor
