Task: Question Generation
Input (English): To determine the incidence of parametrial involvement in a select group of patients with early cervical cancer.', 'We retrospectively reviewed the records of patients with cervical cancer and a maximum tumor diameter of 2 cm, infiltration depth<10 mm and negative pelvic lymph nodes who underwent a radical hysterectomy in two university hospitals. In addition, the literature was reviewed.', '103 patients were identified in our databases that met the abovementioned criteria. In two of these patients (1.94%), parametrial involvement was found. Both patients had LVSI. Literature review revealed 696 patients described in three studies that satisfied the selection criteria. Three (0.43%) of these patients had parametrial involvement. In patients with early stage cervical carcinoma, tumor size<2 cm, infiltration depth<10 mm, negative pelvic lymph nodes and absent LVSI the risk of parametrial involvement is 0.63%.
Output (English): Is the incidence of parametrial tumor involvement in select patients with early cervix cancer too low to justify parametrectomy?
