Objective: Tumor volume and regression after external beam radiotherapy have been shown to be accurate parameters to assess treatment response via magnetic resonance imaging (MRI). The aim of the study was to evaluate the prognostic value of tumor size reduction rate after external beam radiotherapy and chemotherapy prior to brachytherapy. Methods: Patients with locally advanced cervical cancer treated at two French comprehensive cancer centers between 1998 and 2010 were included. Treatment was pelvic external beam radiotherapy with platinum based chemotherapy followed by brachytherapy. Records were reviewed for demographic, clinical, imaging, treatment, and follow-up data. Anonymized linked data were used to ascertain the association between pre-external and post-external beam radiotherapy MRI results, and survival data. Results: 185 patients were included in the study. Median age at diagnosis was 45 years (range 26–72). 77 patients (41.6%) were International Federation of Gynecology and Obstetrics stage IB2-IIA disease and 108 patients (58.4%) were stage IIB-IVA. Median tumor size after external beam radiotherapy and chemotherapy was 2.0 cm (range 0.0–8.0) and median tumor size reduction rate was 62.4% (range 0.0–100.0%). Tumor size and tumor reduction rate at 45 Gy external beam radiotherapy MRI were significantly associated with local recurrence free survival (P<0.001), disease free survival, and overall survival (P<0.05). Tumor reduction rate ≥60% was significantly associated with a decreased risk of relapse and death (HR (95% CI) 0.21 (0.09 to 0.50), P=0.001 for local recurrence free survival; 0.48 (0.30 to 0.77) P=0.002 for disease free survival; and 0.51 (0.29 to 0.88), P=0.014 for overall survival). Conclusions: Tumor size reduction rate >60% between pre-therapeutic and post-therapeutic 45 Gy external beam radiotherapy with concurrent chemotherapy was associated with improved survival. Future studies may help to identify patients who may ultimately benefit from completion surgery, adjuvant chemotherapy, and closer follow-up. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the diagnostic accuracy of intraoperative laparoscopic imaging tools in reference to that of histopathology for detecting endometriotic lesions and to compare them with conventional white-light inspection by performing a systematic review with meta-analysis.Data Sources: We searched the MEDLINE, EMBASE, and CENTRAL databases in addition to citations and reference lists until the end of February 2019.Methods Of Study Selection: Two authors screened 1038 citations for eligibility. We included randomized controlled trials or prospective cohort studies published in English, assessing the accuracy of intraoperative imaging tools for diagnosing endometriosis during laparoscopy. We considered studies using histopathologic evaluation as a standard criterion.Tabulation, Integration, and Results: Seven studies were eligible, including 472 women and 1717 histopathologic specimens, and they involved study of the use of narrow-band imaging (2 studies), 5-aminolevulinic acid-induced fluorescence (2 studies), autofluorescence imaging (1 study), indocyanine green (1 study), and a 3-dimensional robotic laparoscopy (1 study). Two authors extracted data and assessed the validity of the included studies. Bivariate random-effects models and McNemar's test were used to compare the tests and evaluate sources of heterogeneity. Four studies were attributed a high risk of bias, and biopsies of normal-looking peritoneum were not performed to verify the results in 3 studies; both factors were identified as significant sources of heterogeneity, leading to the overestimation of the sensitivity and underestimation of the specificity of imaging tools. In all studies, additional endometriotic lesions were diagnosed with the enhanced imaging tool compared with white-light inspection alone. In the 4 studies that appropriately performed control biopsies (171 women, 448 specimens), enhanced imaging techniques were associated with a higher sensitivity and specificity compared with white-light inspection (0.84 and 0.89 compared with 0.75 and 0.76, respectively, p ≤.001). Adverse events were uncommon (n = 5) and reported only with the use of exogeneous photosensitizers. There were no reports of long-term changes in patient-reported outcomes arising from better detection of endometriosis lesions.Conclusion: Studies report that enhanced imaging allows for the detection of additional endometriotic lesions missed by conventional white-light laparoscopy. The benefits of finding these additional lesions using enhanced imaging compared with white-light inspection alone on long-term postoperative outcomes have not been determined, and these tools should be considered only in a research context at this time.
