Abstract
Background:
Pre-operative tumor grade influences the type of surgery planned for endometrial cancer, while the final grade affects the adjuvant therapy.
Aims and Objectives:
To predict whether pre surgery tumour grade can predict tlymph node dissection and adjuvant therapy in endometriod endometrial cancer.
Methods:
Retrospective observational study. Data was obtained from electronic hospital medical records system. All women with a diagnosis of endometrioid endometrial cancer who attended TMC, Kolkata between September 2011 and June 2015 included. Review of the histology was asked in all patients and MDT was planned for all patients. Most of the patients operated in TMC underwent standard pre-operative imaging work up like MRI pelvis and CT upper abdomen and chest evaluation. Staging/completion surgery included total hysterectomy, BSO, pelvic +/- para aortic lymphadenectomy +/- Omental biopsy. The surgico-pathological evaluation included histology, grade, myometrial invasion, adnexal involvement and nodal involvement.
Results:
155 patients had both initial and final histology. Of total 67 patients with initial grade 1 histology, 8 (12%) were upgraded to G2 and 1 (1.5%) was upgraded to G3. 35 patients with G2 disease 2 (5.7%) were upgraded to G3. Among 8 patients with G3, 7 continued to be G3. Of the 67 patients with initial grade 1, > 50% invasion was seen in 25 (37.3%). Of 35 patients with initial G2, > 50% myometrial invasion was seen in 13 (37.1%) patients. Among 8 initial G3 patients, > 50% invasion was seen in 3 (37.5%) patients. Of these 67 patients with grade 1, pelvic lymph nodes were involved in 4 (6%) patients. None of the grade 2 tumors had pelvic lymph node involvement. One (12.5%) out of 8 patients with initial G3 tumor had pelvic lymph node involvement. Recurrence was seen in 3/67 (4.5%) of G1 patients, 7/35 (20%) with G2 cases and 1/8 (12.5%) with G3 cases.
Conclusion:
Patients with initial G1 disease, about 13% were upgraded. Recurrence rate increased with G2 patients. For all initial grade tumors the mymetrial involvement > 50% was 37%. For initial G1 patients the pelvic lymph node involvement was found to be 6%. For G3 tumor the pelvic lymph node involvement was 12.5%.
