The purpose of this study is to assess the likelihood of detecting stage T1a and T1b cancer in transurethral prostatectomy specimens during the PSA era. Comparison was made of transurethral ...

Researchers examine survival and cancer recurrence in patients with glottic carcinomas receiving one of two treatments.

Key Results. Of the 24,679 patients identified, 15,186 had T1a disease and 9493 had T1b disease. T1a/b prostate cancer represented 3.5% of all prostate cancer without a change in incidence over time.

If T1a/T1mic N0, or if T1b and G1, no adjuvant therapy is recommended, although endocrine therapy can be considered. If T1b N0 and grade 2 to 3, then adjuvant endocrine therapy is recommended if ER ...

The researchers found that for T1a diagnoses, participating pathologists' concordance with the consensus reference diagnosis increased from 44% with AJCC 7 criteria to 54% with AJCC 8 criteria.

Prognosis in women with small (T1mic,T1a,T1b) node-negative operable breast cancer by immunohistochemically selected subtypes.. JCO 29 , 546-546 (2011). DOI: 10.1200/jco.2011.29.15_suppl.546 ...

It’s divided into T1a, T1b and T1c. T1a means that the cancer is in less than 5% of the removed tissue. T1b means that the cancer is in 5% or more of the removed tissue. Your surgeon might find a T1a ...

Of 5670 patients with T1a RCC undergoing surgery in Ontario during the years 1995 to 2014, 2503 (44%) had PN and 3167 (56%) had radical nephrectomy (RN). During a median follow-up period of 6.4 ...

There was also an improvement in intraobserver reproducibility of diagnoses, increasing from 59 to 64% and from 74 to 77% for T1a and T1b or greater invasive melanoma cases, respectively.
