Laparoscopic ovarian transposition prior to pelvic radiation for gynecologic cancer
Bibliographic record
Abstract
This study evaluates a novel technique of laparoscopic ovarian transposition performed by Gynecologic Oncologists prior to pelvic radiation for gynecologic cancer. A retrospective review was completed of all patients that underwent laparoscopic ovarian transposition from February 2007 to June 2017 at one tertiary care cancer. The technique involves salpingectomy, followed by retroperitoneal dissection to move the ovaries lateral to the hepatic and splenic flexures of the colon. Normal ovarian function was defined by the absence of vasomotor symptoms, FSH and menstrual history (if menstruating). The radiation dose to the ovary was calculated through dose volume histograms from three-dimensional image planning. Ten patients had laparoscopic ovarian transposition, of which, eight patients received post-operative external beam radiation to the pelvis (45-59.4 Gy). Four had additional brachytherapy (35.5-40 Gy). Median age and follow up were 29 years (18-37), and 20 months (6-103). Nine patients had cervical and one had vaginal cancer. Four patients were treated with primary radiation, three had radical trachelectomy with adjuvant radiation, and three had radical hysterectomy with one of three receiving adjuvant radiation. No patients developed vasomotor symptoms (0/8 (95% CI 0-19%)). FSH was normal in 2/2 patients. Menses continued post-radiation in 5/7 women who retained their uterus. The median radiation dose to the right and left ovary was 0.51 (0.23-1.1) Gy and 0.53 (0.23-1.1) Gy, respectively. Laparoscopic ovarian transposition with mobilization to the hepatic and splenic flexures of the colon achieves preservation of ovarian function in women prior to pelvic radiation.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
