RESUMO

OBJECTIVES: To assess whether there is a correlation between the length of a conization specimen and the length of the cervix measured by vaginal ultrasonography after the operation PATIENTS AND METHODS: Prospective observational study including patients less than 45 years with measurement of cervical length before and the day of the conization, and measuring the histological length of the specimen. RESULTS: Among the 40 patients enrolled, the average ultrasound measurements before conization was 26.9 mm (± 4.9 mm) against 18.1mm (± 4.4mm) after conization with a mean difference of 8.8mm (± 2.4mm) (difference statistically significant P<.0001). The extent of histological specimen was 9 mm (± 2.2mm) on average. A correlation between ultrasound and histological measurements with a correlation coefficient R=0.85 was found statistically significant (P<0.0001). Moreover, the rate of cervix length remove by loop-excision in our series is 33% (± 8.5%). DISCUSSION: A good correlation between the measurements of the specimen and the cervical ultrasound length before and after conization was found, as a significant reduction in cervical length after conization. The precise length of the specimen should be known in case of pregnancy and the prevention of prematurity due to conization rests on selected indications and efficient surgical technique.

RESUMO

PURPOSE: To evaluate the impact of dosimetry based on MAA SPECT/CT for the prediction of response, toxicity and survival, and for treatment planning in patients with hepatocellular carcinoma (HCC) treated with (90)Y-loaded glass microspheres (TheraSphere®). METHODS: TheraSphere® was administered to 71 patients with inoperable HCC. MAA SPECT/CT quantitative analysis was used for the calculation of the tumour dose (TD), healthy injected liver dose (HILD), and total injected liver dose. Response was evaluated at 3 months using EASL criteria. Time to progression (TTP) and overall survival (OS) were evaluated using the Kaplan-Meier method. Factors potentially associated with liver toxicity were combined to construct a liver toxicity score (LTS). RESULTS: The response rate was 78.8%. Median TD were 342 Gy for responding lesions and 191 Gy for nonresponding lesions (p < 0.001). With a threshold TD of 205 Gy, MAA SPECT/CT predicted response with a sensitivity of 100% and overall accuracy of 90%. Based on TD and HILD, 17 patients underwent treatment intensification resulting in a good response rate (76.4%), without increased grade III liver toxicity. The median TTP and OS were 5.5 months (2-9.5 months) and 11.5 months (2-31 months), respectively, in patients with TD <205 Gy and 13 months (10-16 months) and 23.2 months (17.5-28.5 months), respectively, in those with TD >205 Gy (p = 0.0015 and not significant). Among patients with portal vein thrombosis (PVT) (n = 33), the median TTP and OS were 4.5 months (2-7 months) and 5 months (2-8 months), respectively, in patients with TD <205 Gy and 10 months (6-15.2 months) and 21.5 months (12-28.5 months), respectively, in those with TD >205 Gy (p = 0.039 and 0.005). The median OS was 24.5 months (18-28.5 months) in PVT patients with TD >205 Gy and good PVT targeting on MAA SPECT/CT. The LTS was able to detect severe liver toxicity (n = 6) with a sensitivity of 83% and overall accuracy of 97%. CONCLUSION: Dosimetry based on MAA SPECT/CT was able to accurately predict response and survival in patients treated with glass microspheres. This method can be used to adapt the injected activity without increasing liver toxicity, thus defining a new concept of boosted selective internal radiation therapy (B-SIRT). This new concept and LTS enable fully personalized treatment planning with glass microspheres to be achieved.

RESUMO

INTRODUCTION: The treatment of locally advanced cervical carcinoma of uterine cervix is based on concurrent chemoradiotherapy (CCR). The role of laparoscopic lymphadenectomy before CCR and hysterectomy after CCR is not consensual. PATIENTS AND METHODS: Retrospective multicentric study on 102 patients treated for locally advanced carcinoma of uterine cervix between 1999 and 2008. Disease-free survival and overall survival (OS) were studied. RESULTS: Stages were: stage IB 42%, II 47% and stage III and IVA 11%. All patients received CCR. Eighty-one patients had associated brachytherapy. Sixty-two patients underwent laparoscopic lymphadenectomy before CCR and 31 patients had also para-aortic lymphadenectomy. Eighty-two patients had hysterectomy after CCR. Forty-seven percent (29/62) of patients had a histologically proven pelvic lymph node involvement and 58% (18/31) had a histologically proven para-aortic lymph node involvement. There is no predictor of the presence of residual tumor on hysterectomy. The lymph node involvement before treatment and the presence of residual tumor on hysterectomy were poor prognostic factors on relapse-free survival (SSR) and OS. It has not been shown to benefit from surgery pre- or post-CCR on survival. CONCLUSION: Surgery can provide major prognosis factor and especially lymphadenectomy before CCR can improve the therapeutic strategy but does not demonstrate significant survival benefit.

RESUMO

PURPOSE: This study aims to evaluate the sensibility and specificity of MRI in the detection and size measuring of residual breast cancer in patients treated with neoadjuvant chemotherapy before surgery. PATIENTS AND METHODS: This is a retrospective study of 32 women, who underwent breast MRI before and after neoadjuvant treatment. MRI has been confronted to surgical pathology results. RESULTS: The sensibility of MRI to assess pathologic Complete Response (no invasive residual tumor) was excellent (100%) but the specificity was low (55,5%). There was no false negative case and four false positive cases (Two ductal carcinomas in situ and two scars-like fibrosis). When MRI outcomes were compared with the presence or absence of invasive or in situ residual carcinoma, only one false negative case was noticed (one "in situ" residual tumor). The correlation between tumor size measured by MRI and histopathology was low (r=0,32). Underestimations of tumor size were due to non-continuous tumor regression or invasive lobular carcinoma or association of invasive carcinoma and intra ductal breast cancer. Over estimations of tumor size were due to chemotherapy-induced changes. CONCLUSION: MRI is a sensitive but poorly specific method to assess the pathological complete response after neoadjuvant chemotherapy. Estimation of tumor size and detection of isolated residual in situ carcinoma are fare. Therefore, surgical intervention remains necessary whatever the MRI outcomes.

RESUMO

INTRODUCTION: The cancer of the cervix annually occurs in 150 women in Brittany in the absence of organized screening. MATERIAL AND METHODS: Retrospective study concerning 191 patients treated for an invasive cancer of the uterine cervix between 2000 and 2005 analyzing their cytological past. The average age of the patients was 52 years (22-87 years). The socioeconomic level of the patients was recorded. The distribution of under histological types was: squamous, 73% (54 years average age) and adenocarcinoma, 22% (average age 47 years). All the stages were represented: stage I 46%, II 32%, III 9% and stage IV 13%. RESULTS: Cancer was symptomatic in 89% of the cases and 72% of the patients had not profited from cytological screening according to French recommendations (50% no follow-up, 22% follow-up between three and 10 years), while 28% of the patients had a smear in the three years. The socioeconomic level of the patients strongly influenced the participation in screening. The proportion of patients having an invasive adenocarcinom was 31% in the patients with a smear going back to less than three years (versus 22% in our total population) and this histological subtype was mainly represented in patients less than 35 years old (35%). Lastly, 2,6% of the patients were lost after realization of a pathological smear. CONCLUSION: The extension of screening and its organization remain a priority in our area. The average sensitivity of the smear is illustrated by the on-representation of the adenocarcinoma, in particular among young women.
