级别III:T1a-T3b,N1,M0或T3a-T3c,N0,M0。这一级别包含很多T和N类别的组合,包括任何一个只传播给邻近淋巴结而未传播给其它器官的肿瘤。级别III还包括未传播给淋巴结或远处器官,但已扩散到肾上腺、肾周围脂肪组织的肿瘤,和(或者)已经在连接肾和心脏的大静脉(腔静脉)中滋生的肿瘤。 级别IV:T4,N0-N1,M0,或...
1. 分期——T1 a 粘膜层含有大量的腺体分泌细胞,包括上皮层和粘膜肌层,如果肿瘤侵及粘膜层的话分期为Tla。 就是说粘膜层内也含有少量的肌纤维,经常有人把粘膜肌层误认为固有肌层,这样就容易给患者误导,T1分期误认为是T2分期。 2. 分期——T1 b 第二层为粘膜下层,是介入粘膜层和固有肌层之间,内有大量的淋...
T1:肿瘤已经生长到粘膜下层。 T2:肿瘤已经发展成为肌层,一层更厚,更厚的肌肉,使肌肉受到侵袭。 T3:肿瘤通过肌层生长并进入浆膜层,是大肠某些部分外层下方的结缔组织的薄层,或者已经生长到结肠或直肠周围的组织中。 T4a:肿瘤已经生长到内脏腹膜的表面,这意味着它已经穿透结肠的所有层生长。 T4b:肿瘤已经生长或附着...
第一,西方人群约75%的肿瘤为不良分化,弥漫播散,需要广泛切除以保证阴性切缘。第二,淋巴结受累在T1a,T1b和T2肿瘤中发生率约10%,34%和44%。第三,近端胃切除时,损坏迷走神经分支可能使患者发生严重的慢性反流。最后,为保证足够的D2淋巴结切除,需要行解剖性切除,不清楚更局限的切除是否对肿瘤结局产生不利影响。

For the majority of samples, the tumour was confined to the prostate (6.5% T1, 53.0% T2, 40.0% T3, 0.5% T4). The mean tumour coverage was 73.1x ± 20.6x (median ± standard deviation); the mean non-tumour coverage was 44.1x ± 13.4x. Median clinical follow-up ...
For T1/T2 tumors, the omentum more than 3 cm away from the gastroepiploic artery may be preserved (CQ6). A clinical trial confirming the non-inferiority of omentum preservation to omentectomy for T3 or deeper tumors (JCOG1711) is now underway. Bursectomy Bursectomy for tumors penetrating ...
