Should molecular testing be required for diagnosing synovial sarcoma?
Molecular testing was not required if the diagnosis of SS was certain or probable on the basis of clinical, histologic, and immunohistochemical evaluation. However, it proved to be very helpful or necessary when the diagnosis of SS was only possible and was challenged by other tumor types, mainly other spindle cell sarcomas, round cell sarcomas, carcinomas, myoepitheliomas, and epithelioid fibrosarcomas.
Sarcopenia may be a predictor of pulmonary complications after esophagectomy. Further analysis is needed to clarify whether nutritional intervention improves skeletal muscle mass and thus contributes to reducing postoperative respiratory complications in sarcopenic patients.
