TNM staging of cancer is used to establish the treatment and prognosis for cancer patients, and also allows the assessment of screening programmes and hospital performance. Collection of staging data is becoming a cornerstone for cancer registries. The objective of the study was to assess the completeness of T, N, M and stage grouping registration for all cancers in the Mallorca Cancer Registry in 2006-2008 and to explore differences in T, N, M and stage grouping completeness by site, gender, age and type of hospital.
All invasive cancer cases during the period 2006-2008 were selected. DCO, as well as children's cancers, CNS, unknown primary tumours and some haematological cases were excluded. T, N, M and stage grouping were collected separately and followed UICC (International Union Against Cancer) 7th edition guidelines. For T and N, we registered whether they were pathological or clinical.
Ten thousand two hundred fifty-seven cases were registered. After exclusions, the study was performed with 9283 cases; 39.4 % of whom were women and 60.6 % were men. T was obtained in 48.6 % cases, N in 36.5 %, M in 40 % and stage in 37.9 %. T and N were pathological in 71 % of cases. Stage completeness exceeded 50 % in lung, colon, ovary and oesophagus, although T also exceeded 50 % at other sites, including rectum, larynx, colon, breast, bladder and melanoma. No differences were found in TNM or stage completeness by gender. Completeness was lower in younger and older patients, and in cases diagnosed in private clinics.
T, N, M and stage grouping data collection in population-based cancer registries is feasible and desirable.
癌症的TNM分期用于确定癌症患者的治疗方案和预后，还可用于评估筛查项目和医院绩效。分期数据的收集正成为癌症登记处的基石。本研究的目的是评估2006 - 2008年马略卡癌症登记处所有癌症的T、N、M分期及分期分组登记的完整性，并探讨按部位、性别、年龄和医院类型划分的T、N、M分期及分期分组完整性的差异。
选取2006 - 2008年期间所有侵袭性癌症病例。排除死亡原因不明（DCO）病例、儿童癌症、中枢神经系统肿瘤、原发灶不明肿瘤及部分血液系统病例。T、N、M分期及分期分组分别收集，并遵循国际抗癌联盟（UICC）第7版指南。对于T和N分期，我们记录其是病理分期还是临床分期。
共登记了12570例病例。排除相关病例后，对9283例病例进行了研究；其中39.4%为女性，60.6%为男性。48.6%的病例获得了T分期，36.5%的病例获得了N分期，40%的病例获得了M分期，37.9%的病例获得了分期。71%的病例T和N分期为病理分期。肺癌、结肠癌、卵巢癌和食管癌的分期完整性超过50%，尽管包括直肠癌、喉癌、结肠癌、乳腺癌、膀胱癌和黑色素瘤在内的其他部位T分期也超过了50%。TNM分期或分期完整性在性别上无差异。年轻和老年患者以及在私立诊所诊断的病例的完整性较低。
在基于人群的癌症登记处收集T、N、M分期及分期分组数据是可行且必要的。
