SIRs had been calculated for full disease and stratified centered on decades in the disease diagnosis, cancers brands and you can myositis–cancers intervals ( Tables 2 and you may step three ). 01 (dos.22, step 3.98) [cuatro.thirty-six (dos.62, 6.80) when you look at the men; dos.51 (step 1.seven, 3.59) in women; Desk 2 ]. Increased SIR is detailed in this 1 year regarding myositis prognosis [ (6.75, )] along with into the 2nd and you may third ages immediately after myositis medical diagnosis [3.18 (step one.17, 6.92)]. The most common cancer tumors is non-Hodgkin’s lymphoma (NHL), having good SIR regarding (9.twenty five, ). SIRs of oesophageal cancer [ (cuatro.86, )], multiple myeloma [MM, (dos.77, )], cancer of the lung [6.38 (dos.92, )] and you will adenocarcinoma from unknown first [ACUP, (6.99, )] was indeed including higher than from the general populace ( Dining table dos ).
a good Four cancer tumors times (a couple of cases of breast cancer and another instance all of tummy, uterine cervix and you will kidney cancer) identified anywhere between 1974 and you will 1998 had been excluded about SIR study due to insufficient Korean National Cancer tumors Registry data to have cancers incidence during this period.
b The latest observed level of cancer incidents from inside the Chat otherwise CNM was split because of the expected amount of disease incidents from inside the 281 myositis people. Ergo, the sum of the SIRs away from Chat and you can CNM stands for the complete cancer tumors chance inside the myositis patients.
The complete disease SIR (95% CI) on myositis cohort according to decades- and you can intercourse-coordinated some body regarding the general populace is step three
c The new period are determined by using the go out away from myositis medical diagnosis since a resource. ACUP: adenocarcinoma out-of not familiar pri: cancers concurrent which have productive myositis; socializzare atei CNM: disease non-concurrent which have productive myositis; NHL: non-Hodgkin’s lymphoma; SIR: standardized occurrence ratio.
a good Five cancers circumstances (one or two cases of cancer of the breast plus one situation each of tummy, uterine cervix and you may bladder malignant tumors) diagnosed anywhere between 1974 and you can 1998 was basically omitted on SIR investigation due to diminished Korean National Cancer tumors Registry analysis getting cancers occurrence during this time period.
b New noticed amount of cancer tumors situations inside the Chat otherwise CNM are split up by the requested number of cancer occurrences for the 281 myositis patients. Hence, the sum of the SIRs out-of Speak and CNM is short for the total cancer chance into the myositis clients.
The full cancers SIR (95% CI) on myositis cohort according to ages- and you can sex-paired anybody from the standard inhabitants is step three
c Brand new period are determined utilising the time away from myositis analysis because a guide. ACUP: adenocarcinoma off unknown pri: malignant tumors concurrent having effective myositis; CNM: malignant tumors low-concurrent having productive myositis; NHL: non-Hodgkin’s lymphoma; SIR: standard occurrence proportion.
a for your SIR try computed since observed amount of Cam otherwise CNM divided of the requested number of cancer occurrences from inside the 281 myositis people along side period from three-years in advance of so you’re able to three years after the prognosis away from myositis and/or last go after-right up day otherwise death. ACUP: adenocarcinoma away from not familiar pri: cancers concurrent having energetic myositis; CNM: cancer tumors non-concurrent which have productive myositis; NHL: non-Hodgkin’s lymphoma; SIR: standardized frequency proportion.
a when it comes to SIR was determined as seen amount of Talk or CNM split by questioned level of malignant tumors events for the 281 myositis clients along side months away from 36 months prior to to help you 36 months following prognosis of myositis or even the finally realize-upwards day or death. ACUP: adenocarcinoma off not familiar pri: malignant tumors concurrent that have energetic myositis; CNM: cancer low-concurrent with energetic myositis; NHL: non-Hodgkin’s lymphoma; SIR: standard chance ratio.
More detailed analysis of the cancer risk revealed a CAM SIR of 1.78 (1.19, 2.56) [2.98 (1.59, 5.10) in men; 1.34 (0.77, 2.18) in women] and a CNM SIR of 1.23 (0.75, 1.90) [1.38 (0.5, 2.99) in men; 1.17 (0.64, 1.97) in women] compared with the general population ( Table 2 ). Elevated SIRs were observed for oesophageal cancer [ (4.86, )], NHL [ (5.33, )] and ACUP [ (6.99, )] in CAM, but only for lung cancer in CNM [3.55 (1.15, 8.27); Table 2 ]. When stratified on age at cancer diagnosis, the greatest CAM risk occurred in the seventh decade of life [SIR of 2.61 (1.39, 4.46)], contrasting with CNM where the risk was greatest in the third decade of life [SIR of (4.69, )]. Notably, all three CNM cases occurring at the third decade age stratum were uterine cervical cancers found during periodic health screening at stage 0 (carcinoma in situ ) or 1. The mean interval between myositis and cancer diagnoses was 5.4 (9.0) months in patients with CAM and 71.6 (46.6) months in patients with CNM ( Fig. 1 , P < 0.001), with ?83.3% of CAM cases developing within 1 year of myositis diagnosis. When stratified by myositis–cancer diagnosis intervals, the CAM SIR within 1 year of myositis diagnosis was 9.94 (6.43, ), whereas no significant temporal relationship was found between myositis and CNM ( Table 2 ).
