Traditionally, resections in the abdomen and chest are performed as separate surgical procedures. The aim of this study was to compare a simultaneous versus a sequential approach to residual mass resections. METHODS: A retrospective review was performed of all patients who underwent both retroperitoneal and thoracic resection of post chemotherapy residual masses at the Princess Margaret Cancer Centre between 2002 and 2018. Patients were divided into two groups: Group 1- Simultaneous (Combined Retroperitoneal and Thoracic resections at the same sitting) Group 2: Sequential (Retroperitoneal and Thoracic resections at separate dates). RESULTS: During the study period, 35 simultaneous and 17 sequential resections were performed. The mean age of patient at surgery was 28 years (Range 16-61). The mean follow up from final surgery was 48.3 months (Range 1-239). Histology revealed teratoma in 38 (73.1%) patients, necrosis in 8 (15.4%) and viable tumor in 6 (11.5%). Discordant pathology findings between thoracic and abdominal resections were noted in 16 (30.8%) patients. There was no difference in overall mean length of operating time (mins) between the two groups (635 mins vs 405 mins + 218 mins, p=0.77). There was no difference in overall blood loss (mls) between the two groups (1904 mls vs 2258mls + 301mls, p=0.39). There was no difference in overall mean length of stay (days) between the two groups (14.8 days vs 9.5 days + 8.2days, p=0.72). Patients who underwent sequential surgeries had a longer time from consent to completion of completion of surgery (8.4 months vs 2.1 months, p=0.0001). Overall, there was a recurrence rate of 30.8% (n=16). Two patients have died of testicular cancer. CONCLUSIONS: Simultaneous resection of retroperitoneal and thoracic post chemotherapy metastases is a feasible and safe approach. It does entail multidisciplinary co-operation and a longer primary procedure. Source of Funding: None.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
