[Episode-based bundled payment model: evaluation of medical costs for early operable breast cancer]. / Financement à l'épisode de soins : évaluation du coût d'une chirurgie première pour cancer du sein précoce.

INTRODUCTION: Episode-based bundled payment model is actually opposing to fee-for-service model, intending to incentivize coordinated care. The aims of these study were to determine episode-based costs for surgery in early breast cancer patients and to propose a payment model. METHODS: OPTISOINS01 was a multicenter prospective study including early breast cancer patients from diagnosis to one-year follow up. Direct medical costs, quality and patient reported outcomes were collected. RESULTS: Data from 604 patients were analyzed. Episode-based costs for surgery were higher in case of: planned radical surgery (OR=9,47 ; IC95 % [3,49-28,01]; P<0,001), hospitalization during more than one night (OR=6,73; IC95% [2,59-17,46]; P<0,001), home hospitalization (OR=11,07 ; IC95 % [3,01-173][3,01-54][3,01-543][3,01-54,33]; P<0,001) and re-hospitalization (OR=25,71 ; IC95 % [9,24-89,17; P<0,001). The average cost was 5 268 € [2 947-18 461] when a lumpectomy was planned and 7408 € [4 222-22 565] in case of radical mastectomy. Bootstrap method was applied for internal validation of the cost model showing the reliability of the model with an area under the curve of 0,83 (95 % CI [0,80-0,86]). Care quality and patient reported outcomes were not related to the costs. DISCUSSION: This is the first report of episode-based costs for breast cancer surgery. An external validation will be necessary to validate our payment model.

Laterally Extended Endopelvic Resection of Recurrent Epithelioid Trophoblastic Tumor by Laparoscopy.

We report the resection of a recurrent epithelioid trophoblastic tumor by laparoscopic laterally extended endopelvic resection (LEER). The LEER technique was developed to resect en bloc multiple visceral compartments involving the lateral pelvic wall with negative margins for local control of advanced and recurrent malignancies. Described by Höckel, this procedure is usually performed by a midline laparotomy. Our patient had undergone prior laparotomic surgery including hysterectomy, partial bladder resection, and a right ureteral reimplantation for an epithelioid trophoblastic tumor without adjuvant treatment. She presented a recurrent tumor infiltrating the bladder, the ureter, and the right pelvic wall as well as the internal and external iliac vessels. A vascular surgeon first performed a femorofemoral bypass by bilateral groin incisions with a subcutaneous tunnel. The surgery was then exclusively performed by laparoscopy using the LEER technique including resection of both external and internal iliac vessels and the pelvic wall through the lateral pelvic muscles and iterative bladder resection associated with a ureteral reimplantation using the psoas hitch bladder technique. The patient experienced Clavien-Dindo classification grade II postoperative complications. Histology showed a margin-free resection (R0).
