Stromal invasion of the cervix can be excluded from the criteria for using adjuvant radiotherapy following radical surgery for patients with cervical cancer

The objective of this study was to evaluate the clinical efficacy of conservative laser therapy for early-stage cervical cancer. Seven hundred fifty-two and 271 patients with carcinoma in situ (CIS) and microinvasive squamous cell carcinoma (MIC), respectively, were treated by laser conization with vaporization. One hundred eighty-four patients with preclinical invasive diseases underwent radical surgery without conization. Their postoperative histologic findings and clinical outcomes were evaluated retrospectively. The cone specimens of 1023 cases were reported as showing that 54 had dysplasia, 663 had CIS, 239 had stage Ia1 without lymph vascular space invasion (LVSI), 14 had stage Ia1 with LVSI, 14 had stage Ia2, and 39 had stage Ib1 diseases. Incomplete excision occurred in 4 (7.4%) of 54 dysplasia, 48 (7.2%) of 663 CIS, and 16 (6.7%) of 239 stage Ia1 cases, but failure rates were only 1 (1.9%), 8 (1.2%), and 4 (1.7%), respectively. The other 67 of 1023 cases underwent abdominal operation. Final pathology results were analyzed for 67 and 184 cases with stages Ia1 to Ib1 receiving radical surgery with or without initial laser therapy. Lymph node metastasis was not observed in 154 Ia1 and 30 Ia2 with stromal invasion of under 4 mm in depth regardless of LVSI, but was detected in 2 of 16 Ia2 with stromal invasion of over 4 mm in depth and in 9 of 51 Ib1 cases. CIS and Ia1 disease without LVSI can be treated only by laser therapy. The limit of stromal invasion for conservative laser therapy in stage Ia cancer may be 4 mm in depth regardless of LVSI.

Abstract Objective We used National Cancer Institute’s Surveillance, Epidemiology and End Result database to assess the role of salvage radiotherapy for women with unanticipated cervical cancer after simple hysterectomy. Methods Patients with non-metastatic cervical cancer and meeting inclusion criteria were divided into three groups based on treatment strategy: simple hysterectomy, salvage radiotherapy after hysterectomy and radical surgery. Parallel propensity score-matched datasets were established for salvage radiotherapy group vs. simple hysterectomy group (matching ratio 1: 1), and salvage radiotherapy group vs. radical surgery group (matching ratio 1:2). The primary endpoint was the overall survival advantage of salvage radiotherapy over simple hysterectomy or radical surgery within the propensity score-matched datasets. Results In total, 2682 patients were recruited: 647 in the simple hysterectomy group, 564 in the salvage radiotherapy group and 1471 in the radical surgery group. Age, race, histology, grade, FIGO stage, insured and marital status and chemotherapy were comprised in propensity score-matched. Matching resulted in two comparison groups with neglectable differences in most variables, except for black race, FIGO stage III and chemotherapy in first matching. In the matched analysis for salvage radiotherapy vs. simple hysterectomy, the median follow-up time was 39 versus 32 months. In the matched analysis for salvage radiotherapy vs. radical surgery, the median follow-up time was 39 and 41 months, respectively. Salvage radiotherapy (HR 0.53, P = 0.046) significantly improved overall survival compared with simple hysterectomy, while salvage radiotherapy cannot achieve similar overall survival to radical surgery (HR 1.317, P = 0.045). Conclusions This is the largest study of the effect of salvage radiotherapy on overall survival in patients with unanticipated cervical cancer. Salvage radiotherapy can improve overall survival compared with hysterectomy alone, while cannot achieve comparable survival to radical surgery.
