The association between the lymphovascular invasion in the transurethral resection pathology and recurrence, progression, and metastasis of the disease in patients with t1 bladder cancer

Objective: Our study aimed to assess the relationship between lymphovascular invasion (LVI) on transurethral resection of bladder carcinoma (TURB) pathology and disease progression, recurrence and development of metastasis in patients with T1 bladder cancers. Material and Methods: The clinical records of patients having undergone TURB in our clinic were retrospectively reviewed. Newly diagnosed pT1 patients with urothelial bladder cancer were included in the study. Of the patients; sex, age, initial diagnosis or recurrence, tumor size, tumor number, grade, presence of Cis, presence of intravesical treatment, follow up times, recurrence, progression, metastasis and lymphovascular invasion were recorded. Patients were divided into two groups according to LVI status and compared in terms of recurrence, progression and metastasis. Results: Ninety three patients with pT1 urothelial bladder cancer were enrolled. The mean age of the patients was 63.96 ± 9.94 (36-84). The mean tumor size was 4.29 ± 2.54 cm (1-10 cm) and the mean number of tumors was 2.46 ± 1.48 (1-5). LVI was detected in 27 patients (29%). Of the 51 patients with recurrence, 18 had LVI and 33 had no LVI (p> 0.05). Of the 22 patients with progression, 14hadLVIand8hadnoLVI(p<0.01).Ofthe15 patients with metastasis, 11 had LVI and 4 had no LVI (p <0.01). Conclusion: In the patients with T1 bladder cancer, LVI after TURB is associated with the progression and metastasis of disease. Therefore, it is a prognostic factor that can be used when planning the follow-up and treatment of the disease. When planning the treatment of patients with superficial bladder tumors with LVI, we think that they should be more careful and aggressive than non-LVI patients
