    Abstract:
    OBJECTIVE: We studied the clinical patterns and outcome of patients with FIGO (1985) Stage 1b cervical cancer. In particular, looking at the clinico-pathological characteristics in relation with disease recurrence. PATIENTS & METHODS: Ninety-nine Asian patients were managed at (the former) K K Hospital, Singapore, from 1987 to 1991. The mean and median follow-up periods were 67 and 60 months respectively. This study was performed in 1995. RESULTS: The majority of the patients (81%) was treated by radical hysterectomy with or without adjuvant radiotherapy/chemotherapy while 15% were treated by radical pelvic radiotherapy alone and 4% of patients had pelvic radiotherapy following the diagnosis of cervical cancer after a simple hysterectomy. Thirteen patients developed tumour recurrence (13.1%). In these patients, there was a greater proportion of adenocarcinomas (31% vs 13%, p = 0.1065), lymph node metastases (45% vs 20%, p = 0.09) and surgical margins involvement (45% vs 7%) 7%, p = 0.004) while there seemed to be no difference in histological sub-types, vascular space involvement and cytological grading. The relative risks of developing tumour recurrence in patients with adenocarcinoma was 2.5 times (95% CI: 0.88-7.05), lymph-node metastasis: 2.3 times (95% CI: 0.96-4.93) and involved surgical margins; 5.9 times (95% CI: 2.27-15.5). The mean time to recurrence were 21.7 months with all of them detected within 36 months following primary therapy. All of them had abnormal physical findings while routine follow-up Pap smear was positive in only one patient (8%). In general, the outcome of salvage treatment was poor. CONCLUSIONS: In our group of patients with FIGO Stage lb cervix cancer, majority had radical surgery performed initially. Thirteen percent had disease recurrence, in which there were greater proportions of patients with adenocarcinoma, lymph-node metastasis, and involved surgical margins. The mean time-to-recurrence was 21.7 months with all detected by 36 months. Routine follow-up Pap smear seemed to be a poor indicator of disease status.
