Clinical outcome of FIGO 2018 stage IB3/IIA2 cervical cancer treated by neoadjuvant chemotherapy followed by radical surgery due to lack of radiotherapy equipment: A retrospective comparison with concurrent chemoradiotherapy.

This study aimed to assess neoadjuvant chemotherapy's clinical outcomes such as efficacy, toxicity, and survival outcomes followed by radical hysterectomy ((NACT-RS) among women with cervical cancer stage IB3 and IIA2, by comparing concurrent chemoradiotherapy (CCRT) and NACT-RS. The study retrospectively reviewed patients with (2018 FIGO) stage IB3 and IIA2 cervical cancer who received preoperative neoadjuvant chemotherapy followed by NACT-RS or concurrent chemoradiotherapy (CCRT). The outcome measures were the 5-year survival and complication rates between the two groups. The median follow-up was 75 months. In total, 218 patients had stage IIA2, 136 patients had stage IB3, 201 patients received CCRT, and 153 patients received preoperative NACT-RS. In the CCRT group, the incidence of early complications (myelosuppression, gastrointestinal and urinary) was higher compared with that in the NACT-RS group (76.1 vs. 26.1%; p < 0.001, respectively). There was no significant difference between the two study groups concerning late complications. Five-year PFS was 79.9% and 85.5% in the NACT-RS and CCRT groups, respectively (p = 0.093). Five-year OS was 86.9% and 85.5% in the NACT-RS and CCRT groups, respectively (p = 0.97). In the multivariate clinicopathologic characteristics analysis for OS, initial tumor size > 4.3 cm (HR 5.11; p < 0.001), AC/ASC (HR 1.89; p = 0.02), histologic grade 2-3 (HR 2.25; p = 0.04), and 2018 FIGO stage IIA2 (HR 8.67; p < 0.001) were independent risk factors. The survival of patients with stage IB3 and IIA2 cervical cancer treated with NACT-RS was similar to that of patients treated with CCRT without increasing side effects.

Chemotherapy initiation with single-course methotrexate alone or combined with dactinomycin versus multi-course methotrexate for low-risk gestational trophoblastic neoplasia: a multi-centric randomized clinical trial.

We aimed to evaluate the effectiveness and safety of single-course initial regimens in patients with low-risk gestational trophoblastic neoplasia (GTN). In this trial (NCT01823315), 276 patients were analyzed. Patients were allocated to three initiated regimens: single-course methotrexate (MTX), single-course MTX + dactinomycin (ACTD), and multi-course MTX (control arm). The primary endpoint was the complete remission (CR) rate by initial drug(s). The primary CR rate was 64.4% with multi-course MTX in the control arm. For the single-course MTX arm, the CR rate was 35.8% by one course; it increased to 59.3% after subsequent multi-course MTX, with non-inferiority to the control (difference -5.1%,95% confidence interval (CI) -19.4% to 9.2%, P = 0.014). After further treatment with multi-course ACTD, the CR rate (93.3%) was similar to that of the control (95.2%, P = 0.577). For the single-course MTX + ACTD arm, the CR rate was 46.7% by one course, which increased to 89.1% after subsequent multi-course, with non-inferiority (difference 24.7%, 95% CI 12.8%-36.6%, P < 0.001) to the control. It was similar to the CR rate by MTX and further ACTD in the control arm (89.1% vs. 95.2%, P =0.135). Four patients experienced recurrence, with no death, during the 2-year follow-up. We demonstrated that chemotherapy initiation with single-course MTX may be an alternative regimen for patients with low-risk GTN.

Efficacy of preoperative brachytherapy for controlling vaginal bleeding in early-stage cervical cancer: a retrospective study.

BACKGROUND: In our clinical study, 11% of the patients with early-stage cervical cancers had different degrees of vaginal bleeding, which required a preoperative intervention. We set to assess the efficacy and safety of preoperative high-dose rate vaginal ovoid brachytherapy (HDR-VOBT) for the treatment of vaginal bleeding in women with early cervical cancer. METHODS: We retrospectively identified and reviewed patients with vaginal bleeding and early-stage cervical carcinoma, treated between January 2011 and December 2014 (median follow-up of 69 months). Of the 116 patients, 59 received preoperative HDR-VOBT (a dose of 8 Gy at 0.5 cm from the tumor surface), and 57 received traditional vaginal packing with gauze alone, followed by radical hysterectomy and lymphadenectomy. Analysis of the clinical parameters was performed using the chi-square test. The outcome measures were the 3- and 5-year survival and the complication rate. RESULTS: From the 116 patients, 25 had stage IB1, 49 had stage IB2, and 42 had stage IIA1 cervical cancer. No differences were observed regarding the 5-year overall survival (OS) (91.5% vs. 91.2%) and disease-free survival (DFS) (76.3% vs. 86%) between the preoperative HDR-VOBT group and the vaginal packing with gauze group. The mean volume of blood loss due to vaginal bleeding after treatment was 83.4 (range: 30-150) mL: 56.8 (range: 30-80) mL in the preoperative HDR-VOBT group and 111.1 (range: 80-150) mL in the gauze packing group (P<0.001). The mean time to achieve hemostasis was 3.5 h in the preoperative HDR-VOBT group and 8.1 h in the vaginal packing with gauze group (P<0.001). There was no significant difference in postoperative risk factors, complications, and survival between the two groups. CONCLUSIONS: Preoperative HDR-VOBT with a dose of 8 Gy at 0.5 cm from the surface of the tumor has a better hemostatic effect than vaginal packing with gauze, with no additional complications and no need for adjuvant treatment after the operation.
