Neoplastic invasion of the connective stalks in transitional cell papillary tumors (TCPT) of the bladder

Abstract: Neoplastic invasion into the connective stalks of transitional cell papillary tumors of the bladder was assessed in TUR specimens from new cases. There were 21 G1 cases, none of which showed invasion of the connective tissue stalk; this compared with definite invasion in 19 of 77 G2 cases (25%) and in 16 of 17 G3 cases (94%). During a 5 year follow-up period more of the stalk invasive cases had an unfavorable course (fatal outcome or total cystectomy) than of the stalk non-invasive cases; this was statisticall… Show more

“…These invasive cells and tumour nests are still confined within the exophytic tumour component at a significant distance from the proper bladder wall and associated deeper vasculature, and are thus less likely to spread and progress than tumours invading the PUC base. The significance of separating stalk‐invasive tumours was recognized earlier in a few studies, a systematic approach and strict selection criteria were lacking . For instance, studies by Hermann and Tommasini‐Degna included in their cohorts cases with associated CIS, thus increasing the numbers of patients but potentially affecting outcomes.…”

For instance, studies by Hermann and Tommasini‐Degna included in their cohorts cases with associated CIS, thus increasing the numbers of patients but potentially affecting outcomes. The pT1 tumours were substaged into: pT1a—invasion of the tumour stalk without involvement of the LP under the stalk; pT1b—LP invasion under the tumour stalk but superficial to the MM; and pT1c—invasion into or deeper than the MM without involvement of the muscularis propria .…”
